Abstract
Peripheral artery disease (PAD) is an atherosclerotic occlusive disease of the lower extremities and is associated with an increased risk of amputation and cardiovascular events. The interplay between diabetes and PAD is complex, influenced by shared risk factors such as hypertension, dyslipidemia, and smoking. High rates of undiagnosed diabetes, coupled with barriers to accessing care, contribute to the complexity of managing PAD. Unique to the Sub-Sahara region is associations with communicable diseases such as human immunodeficiency virus and tuberculosis which further complicates the epidemiological landscape. Comprehensive management strategies, including lifestyle modifications, pharmacological interventions, and revascularization procedures, are essential. However, the region faces challenges such as inadequate healthcare infrastructure and high costs of treatment. This narrative review highlights the epidemiology of PAD in people with diabetes, the risk factors associated with PAD, the impact of PAD on the morbidity and mortality of individuals with diabetes, as well as the management of PAD in individuals with diabetes, with attention geared toward Sub-Saharan Africa These insights are critical for developing effective strategies to mitigate the burden of PAD in diabetes, especially in Sub-Saharan Africa. Further research is essential to understand the associations between diabetes and other diseases in the region.

Abstract
Type 1 diabetes is an autoimmune condition resulting in insulin deficiency and eventual loss of pancreatic β cell function requiring lifelong insulin therapy. Since the discovery of insulin more than 100 years ago, vast advances in treatments have improved care for many people with type 1 diabetes. Ongoing research on the genetics and immunology of type 1 diabetes and on interventions to modify disease course and preserve β cell function have expanded our broad understanding of this condition. Biomarkers of type 1 diabetes are detectable months to years before development of overt disease, and three stages of diabetes are now recognized. The advent of continuous glucose monitoring and the newer automated insulin delivery systems have changed the landscape of type 1 diabetes management and are associated with improved glycated hemoglobin and decreased hypoglycemia. Adjunctive therapies such as sodium glucose cotransporter-1 inhibitors and glucagon-like peptide 1 receptor agonists may find use in management in the future. Despite these rapid advances in the field, people living in under-resourced parts of the world struggle to obtain necessities such as insulin, syringes, and blood glucose monitoring essential for managing this condition. This review covers recent developments in diagnosis and treatment and future directions in the broad field of type 1 diabetes.

Abstract
Background The burden of cardiovascular diseases (CVDs) and response to health systems vary widely at the subnational level in India. Our study aimed to assess the variation in state-level access to medicines for CVDs by comparing the essential medicines lists (EMLs) at the national and subnational levels in India and by rapid appraisal of the existing policies and processes of drug procurement. Methods We assessed the inclusion of six classes of medicines for CVDs in the recent and publicly available national and subnational EMLs from July to September 2018 in the states of Telangana and Madhya Pradesh. We examined the drug procurement and distribution policies and processes using documentary review and five key informant interviews between March and June 2018. Results The WHO's EML, India's national EML, and 21 of 28 publicly available (75%) Indian state and Union Territory EMLs included all six classes of essential medicines for CVDs. However, some medicines were not included in the policy packages of essential medicines meant for primary health centres. Both the states used centralized tendering and decentralized distribution as part of the public sector drug procurement process. The requirement was based on the previous year's consumption. The approximate time between procurement planning and distribution was 7-8 months in both the states. Conclusion Substantial variation exists in the selection of drugs for CVDs in EMLs at the subnational level in India. Improving forecasting techniques for requirement of medicines and reducing time lags between forecasting and distribution to health facilities may allow for better access to essential medicines.

Abstract
Diabetes is a non-communicable ailment that has adverse effects on the individual's overall well-being and productivity in society. The main objective of this study was to examine the empirical literature concerning the association between diabetes and poverty and the accessibility and utilization of medical care services among diabetic patients. The diabetes literature was explored using a literature review approach. This review revealed that diabetes is an ailment that affects all individuals irrespective of socioeconomic status; however, its pre-valence is high in low-income countries. Hence, despite the higher prevalence of diabetes in developing countries compared with developed countries, diabetes is not a poor man's ailment because it affects individuals of all incomes. While the number of diabetic patients that access and utilize diabetes medical care services has increased over the years, some personal and institutional factors still limit patients' access to the use of diabetes care. Also, there is a lacuna in the diabetes literature concerning the extent of utilization of available healthcare services by diabetic patients.

Abstract
Non-governmental organizations play a vital part in the achievement of the Sustainable Development Goals as defined by the United Nations. These Goals also include targets related to noncommunicable diseases. However, non-governmental organizations have played a limited role in this area despite such diseases causing the bulk of morbidity and mortality worldwide. Through their activities, non-governmental organizations should aim to strengthen health systems, yet they often only support these for a single disease. Mali, like many other low- and middle-income countries, is facing an increasing burden of diabetes and a health system not adapted to address this challenge. Santé Diabète, a non-governmental organization based in Mali since 2003, has been working specifically on diabetes, and has developed a wide range of activities to improve the national health system. This paper describes changes in the diabetes environment in Mali between 2004 and 2018 based on two health system assessments carried out using a Rapid Assessment Protocol. Over this period, the health system was strengthened with regard to financing and access to medical products. Leadership and governance, service delivery and health workforce were all improved but still partially rely on sustained support from Santé Diabète. The key lesson from this study is that to be effective in changing the management of noncommunicable diseases in a low- and middle-income country, non-governmental organizations need to play a variety of roles, many of which may change over time.

Abstract
INTRODUCTION Survival from type 1 diabetes Mellitus is low in lower-income countries with underdeveloped health systems. Support programs from partners like life for a child (LFAC) and changing diabetes in children (CDiC) were implemented in Tanzania in 2005 to provide diabetes care to children and youth. No evaluation of survival has been done since their implementation. OBJECTIVE To assess the survival of children and youth living with diabetes mellitus (CYLDM) in Tanzania. METHODS A retrospective data collection from 39 clinics of CYLDM was done by extracting data from the diabetes registry between 1991 and 2019. Three cohort were analyzed (1) Cohort 1991-2004 (pre-implementation), (2) Cohort 2005-2010 (during implementation), and (3) 2011-2019 (after the implementation of LFAC/CDiC). Data were analyzed using STATA-version 14. RESULTS A total of 3822 data of CYLDM were extracted, mean age at diagnosis was 13.8 (±5) years. Approximately fifty-one percent (50.8%) were male. The total observation time was 28 years, and the Median duration of diabetes of 5 (IQR2, 8) years. Total death was 95 (3%), with a mean age at death of 17.7 (SD 4.7) years. The last cohort (2011-2019) had more diagnosis 2353 (72.7%), as compared to the <2005 cohort with only 163(5%). The survival improved from 59% before 2005 to 69% in the last cohort (2011-2019). CONCLUSION The implemented programs have facilitated the diagnosis and retention of CYLDM in the health care system. In doing so, it has also increased the survival probability in Tanzania compared to the early 90s.

Abstract
BACKGROUND Despite significant achievements in the prevention and control of NCDs in Iran, these conditions are still the biggest challenges to Iran's healthcare system and are estimated to account for 78.1 percent of all deaths. Therefore, this study aimed to reflect on the potential challenges standing in the way to implement the relevant policies, empower the dimensions of governance, and react in an effective and timely manner by Iran's healthcare system to NCDs. METHODS This study was conducted with a qualitative approach using the conventional content analysis method. A total of 46 senior managers involved in the prevention and control of NCDs at the medical sciences universities across Iran were recruited through the purposive sampling method and were interviewed via semi-structured interviews. Graneheim and Lundman's approach was utilized to analyze the data. RESULTS According to the analysis of the senior managers' viewpoints, current challenges to implement the program for the prevention and control of NCDs in Iran could be placed into six main categories, including financing, human resources, infrastructure and inputs, legal, executive, administrative, as well as inter-sectoral collaboration, and management and policy-making challenges with their own sub-categories. CONCLUSION The results revealed that financing was the biggest challenge to successfully implementing the program for the prevention and control of NCDs in Iran. However, strengthening Iran's healthcare system in the field of the prevention of NCDs demanded more innovative measures and strategies, such as the empowerment of human resources, the effective use of intra- and inter-sectoral collaboration, and non-governmental organizations and charities, along with the exploitation of evidence-based studies during policy-making and decision-making processes, with no need for financial resources.

Abstract
OBJECTIVE Contemporary data on the attainment of optimal diabetes treatment goals and the burden of diabetes complications in adult populations with type 2 diabetes in Africa are lacking. We aimed to document the current status of attainment of three key indicators of optimal diabetes care and the prevalence of five diabetes complications in adult African populations with type 2 diabetes. METHODS We systematically searched Embase, PubMed and the Cochrane library for published studies from January 2000 to December 2020. Included studies reported any information on the proportion of attainment of optimal glycated haemoglobin (HbA1c), blood pressure (BP) and low-density lipoprotein cholesterol (LDLC) goals and/or prevalence of five diabetes complications (diabetic peripheral neuropathy, retinopathy, nephropathy, foot ulcers and peripheral arterial disease). Random effect model meta-analysis was performed to determine the pooled proportion of attainment of the three treatment goals and the prevalence of five diabetes complications. RESULTS In total, 109 studies with a total of 63 890 participants (53.3% being females) were included in the meta-analysis. Most of the studies were conducted in Eastern African countries (n=44, 40.4%). The pooled proportion of attainment of an optimal HbA1c, BP and LDLC goal was 27% (95% CI 24 to 30, I2=94.7%), 38% (95% CI 30 to 46, I2=98.7%) and 42% (95% CI 32 to 52, I2=97.4%), respectively. The pooled prevalence of diabetic peripheral neuropathy, retinopathy, diabetic nephropathy, peripheral arterial disease and foot ulcers was 38% (95% CI 31 to 45, I2=98.2%), 32% (95% CI 28 to 36, I2=98%), 31% (95% CI 22 to 41, I2=99.3%), 19% (95% CI 12 to 25, I2=98.1%) and 11% (95% CI 9 to 14, I2=97.4%), respectively. CONCLUSION Attainment of optimal diabetes treatment goals, especially HbA1c, in adult patients with type 2 diabetes in Africa remains a challenge. Diabetes complications, especially diabetic peripheral neuropathy and retinopathy, are highly prevalent in adult populations with type 2 diabetes in Africa.

Global incidence, prevalence, and mortality of type 1 diabetes in 2021 with projection to 2040: a modelling study. Lancet Diabetes Endocrinol 2022; 10:741-760. [PMID: 36113507 DOI: 10.1016/s2213-8587(22)00218-2] [Citation(s) in RCA: 411] [Impact Index Per Article: 137.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/22/2022] [Revised: 07/15/2022] [Accepted: 07/15/2022] [Indexed: 10/14/2022]
Abstract
BACKGROUND Accurate data on type 1 diabetes prevalence, incidence, associated mortality and life expectancy are crucial to inform public health policy, but these data are scarce. We therefore developed a model based on available data to estimate these values for 201 countries for the year 2021 and estimate the projected prevalent cases in 2040. METHODS We fitted a discrete-time illness-death model (Markov model) to data on type 1 diabetes incidence and type 1 diabetes-associated mortality to produce type 1 diabetes prevalence, incidence, associated mortality and life expectancy in all countries. Type 1 diabetes incidence and mortality data were available from 97 and 37 countries respectively. Diagnosis rates were estimated using data from an expert survey. Mortality was modelled using random-forest regression of published type 1 diabetes mortality data, and life expectancy was calculated accordingly using life tables. Estimates were validated against observed prevalence data for 15 countries. We also estimated missing prevalence (the number of additional people who would be alive with type 1 diabetes if their mortality matched general population rates). FINDINGS In 2021, there were about 8·4 (95% uncertainty interval 8·1-8·8) million individuals worldwide with type 1 diabetes: of these 1·5 million (18%) were younger than 20 years, 5·4 million (64%) were aged 20-59 years, and 1·6 million (19%) were aged 60 years or older. In that year there were 0·5 million new cases diagnosed (median age of onset 39 years), about 35 000 non-diagnosed individuals died within 12 months of symptomatic onset. One fifth (1·8 million) of individuals with type 1 diabetes were in low-income and lower-middle-income countries. Remaining life expectancy of a 10-year-old diagnosed with type 1 diabetes in 2021 ranged from a mean of 13 years in low-income countries to 65 years in high-income countries. Missing prevalent cases in 2021 were estimated at 3·7 million. In 2040, we predict an increase in prevalent cases to 13·5-17·4 million (60-107% higher than in 2021) with the largest relative increase versus 2021 in low-income and lower-middle-income countries. INTERPRETATION The burden of type 1 diabetes in 2021 is vast and is expected to increase rapidly, especially in resource-limited countries. Most incident and prevalent cases are adults. The substantial missing prevalence highlights the premature mortality of type 1 diabetes and an opportunity to save and extend lives of people with type 1 diabetes. Our new model, which will be made publicly available as the Type 1 Diabetes Index model, will be an important tool to support health delivery, advocacy, and funding decisions for type 1 diabetes.

Barriers and Facilitators in Access to Diabetes, Hypertension, and Dyslipidemia Medicines: A Scoping Review. Public Health Rev 2022; 43:1604796. [PMID: 36120091 PMCID: PMC9479461 DOI: 10.3389/phrs.2022.1604796] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/25/2022] [Accepted: 07/27/2022] [Indexed: 12/03/2022] Open
Abstract
Objective: Identify barriers and facilitators in access to medicines for diabetes, hypertension, and dyslipidemia, considering patient, health provider, and health system perspectives. Methods: Scoping review based on Joanna Briggs methodology. The search considered PubMed, Cochrane Library, CINAHL, Academic Search Ultimate, Web of Science, SciELO Citation Index, and grey literature. Two researchers conducted screening and eligibility phases. Data were thematically analyzed. Results: The review included 219 documents. Diabetes was the most studied condition; most of the evidence comes from patients and the United States. Affordability and availability of medicines were the most reported dimension and specific barrier respectively, both cross-cutting concerns. Among high- and middle-income countries, identified barriers were cost of medicines, accompaniment by professionals, long distances to facilities, and cultural aspects; cost of transportation emerges in low-income settings. Facilitators reported were financial accessibility, trained health workers, medicines closer to communities, and patients' education. Conclusion: Barriers and facilitators are determined by socioeconomic and cultural conditions, highlighting the role of health systems in regulatory and policy context (assuring financial coverage and free medicines); providers' role bringing medicines closer; and patients' health education and disease management.

Abstract
AIMS To describe and compare the health system responses for type 1 diabetes in Kyrgyzstan, Mali, Peru and Tanzania. METHODS The Rapid Assessment Protocol for Insulin Access, a multi-level assessment of the health system, was implemented in Kyrgyzstan, Mali, Peru and Tanzania using document reviews, site visits and interviews to assess the delivery of care and access to insulin. RESULTS Despite the existence of noncommunicable or diabetes strategies and Universal Health Coverage policies including diabetes-related supplies, this has not necessarily translated into access to insulin or diabetes care for all. Insulin and related supplies were often unavailable and unaffordable. Across the four countries test strips and insulin, when paid for by the individual, represented respectively 48-82% and 25-36% of total costs. Care was mainly delivered at tertiary-level hospitals by specialists. Only Kyrgyzstan had data collection systems integrated into the Ministry of Health structure. In addition, issues with healthcare worker training and education and empowerment of people with diabetes were present in these health systems. CONCLUSIONS People with type 1 diabetes in these countries face different barriers, including the cost of insulin and care. Given the renewed attention to diabetes on the global health agenda tailored health system responses for type 1 diabetes are needed. Insulin should be prioritized as it is the foundation of type 1 diabetes care, but other elements of care and support need to be fostered by different actors.

Abstract
AIMS The focus of health system interventions for noncommunicable diseases and diabetes focus mainly on primary health care responses. However, existing interventions are not necessarily adapted for the complex management of type 1 diabetes (T1DM). We aimed to identify and describe health system interventions which have been developed to improve the management of T1DM globally. METHODS We conducted a scoping review by searching MEDLINE, Embase, and Global Health using OVID for peer-review articles published in either English, Spanish, Portuguese or French in the last 10 years. We classified the intervention strategies according to the Effective Practice and Organization of Care (EPOC) taxonomy for health system interventions and the World Health Organization (WHO) health system building blocks. RESULTS This review identified 159 health system interventions to improve T1DM management. Over half of the studies focused only on children or adolescents with type 1 diabetes. Only a small fraction of the studies were conducted in low-and-middle income countries (LMICs). According to the EPOC taxonomy, the most frequently studied category was delivery arrangement interventions, while implementation strategies and financial arrangements were less frequently studied. Also, governance arrangements domains were not studied. The most common combination of intervention strategies included self-management with either telemedicine, use of information and smart home technologies. CONCLUSIONS There is a need to expand potential interventions to other EPOC strategies to assess their potential effect on health outcomes in people with T1DM, as well as to involve more LMIC settings as the impact may be greater in these settings.

Access to Insulin Products in Pakistan: A National Scale Cross-Sectional Survey on Prices, Availability, and Affordability. Front Pharmacol 2022; 13:820621. [PMID: 35431962 PMCID: PMC9010947 DOI: 10.3389/fphar.2022.820621] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/23/2021] [Accepted: 03/03/2022] [Indexed: 12/16/2022] Open
Abstract
Background: Diabetes is among the top ten most prevalent diseases in Pakistan, and the availability of medicines to treat the disease is vital for a great percentage of the country’s population. Insulin was discovered a century ago; however, its access in several parts of the globe remains an issue. This study aims to evaluate prices, availability, and affordability (access components) of insulin and five comparator medicine access in Pakistan. Methods: A nationwide cross-sectional survey was conducted to evaluate the access to insulin and some comparator medicines in eight cities of Pakistan, using a modified WHO/HAI methodology. The survey included 80 medicine outlets, i.e., 40 private pharmacies and 40 public hospitals. Data for every unique insulin product available in the Pakistani market were obtained, including five comparator medicines. Percentage availability, median unit prices (MUPs), and affordability (the number of days’ wages (NDWs) required for a month’s course by the lowest-paid unskilled government worker) of all products were calculated, including originator brands (OBs) and biosimilar (BS) products. Results: Of all insulin products surveyed (n = 320), 87.5% were manufactured by foreign multinational companies (MNCs). None of the insulin products had an ideal availability of 80% in any of the surveyed health facilities. In the public sector, none of the insulin products had an availability of more than 50%. In the public sector, the overall availability of human insulin was 70% (including OB and BS). While in the private sector, the overall availability of human insulin was 90% and that of analog insulin was 62.5%. The analog insulin products were 72.8% costlier than the human insulin products. The median prices of BS insulin were 25.4% lower than the OB products, indicating that almost one-fourth of the cost could be saved by switching to BS human insulin from OB human insulin. All oral anti-diabetic medicines were found to be affordable, whereas none of the insulin was affordable. The NDWs for human and analog insulin were 1.38 and 5.06. Conclusion: In Pakistan, the insulin availability falls short of the WHO’s benchmark of 80%. Insulin continues to be unaffordable in both private and government sectors. To increase insulin access, the government should optimize insulin procurement at all levels, promote local production, enforce biosimilar prescribing, and provide financial subsidies for these products.

[PMID: 34774146 DOI: 10.1016/s0140-6736(21)02247-9] [Citation(s) in RCA: 17] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/16/2021] [Revised: 10/04/2021] [Accepted: 10/05/2021] [Indexed: 12/11/2022]
Abstract
Type 1 diabetes is on the rise globally; however, the burden of mortality remains disproportionate in low-income and middle-income countries (LMICs). As 2021 marks 100 years since the discovery of insulin, we revisit progress, global burden of type 1 diabetes trends, and understanding of the pathogenesis and management practices related to the disease. Despite much progress, inequities in access and availability of insulin formulations persist and are reflected in differences in survival and morbidity patterns related to the disease. Some of these inequities have also been exacerbated by health-system challenges during the COVID-19 pandemic. There is a clear opportunity to improve access to insulin and related essential technologies for improved management of type 1 diabetes in LMICs, especially as a part of universal health coverage. These improvements will require concerted action and investments in human resources, community engagement, and education for the timely diagnosis and management of type 1 diabetes, as well as adequate health-care financing. Further research in LMICs, especially those in Africa, is needed to improve our understanding of the burden, risk factors, and implementation strategies for managing type 1 diabetes.

Inequalities in the Global Burden of Chronic Kidney Disease Due to Type 2 Diabetes Mellitus: An Analysis of Trends from 1990 to 2019. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2021; 18:ijerph18094723.

Abstract
The prevalence of type 2 diabetes mellitus (T2DM) and the burden of complications are increasing worldwide. Chronic kidney disease (CKD) is one serious complication. Our aim was to investigate the trends and inequalities of the burden of CKD due to T2DM between 1990 and 2019. Data were obtained from the Global Health Data Exchange database. Age-standardized incidence, mortality, and DALYs rates of CKD were used to estimate the disease burden across the Human Development Index (HDI). Joinpoint regression was performed to assess changes in trend, and the Gini coefficient was used to assess health inequality. A higher incidence was observed in more developed countries (p < 0.001), while higher mortality and DALYs rates were experienced in low and middle HDI countries in 2019 (p < 0.001). The trend of incidence has increased since 1990 (AAPC: 0.9–1.5%), while slight decrease was observed in low HDI countries in mortality (APC: −0.1%) and DALYs (APC: −0.2%). The Gini coefficients of CKD incidence decreased from 0.25 in 2006 to 0.23 in 2019. The socioeconomic development was associated with disease burden. Our findings indicate that awareness of complications should be improved in countries with high incidence, and cost-effective preventive, diagnostic, and therapeutic tools are necessary to implement in less developed regions.

[PMID: 33879174 PMCID: PMC8056633 DOI: 10.1186/s12939-021-01442-1] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/22/2020] [Accepted: 04/01/2021] [Indexed: 11/16/2022] Open
Abstract
BACKGROUND The rising prevalence of type 2 diabetes results in a worldwide public healthcare crisis, especially in low- and middle-income countries (LMICs) with unprepared and overburdened health systems mainly focused on infectious diseases and maternal and child health. Studies regarding type 2 diabetes in LMICs describe specific interventions ignoring a comprehensive analysis of the local factors people see influential to their health. This study aims to meet this research gap by exploring what people with type 2 diabetes in Bolivia need to maintain or improve their health, how important they perceive those identified needs and to what extent these needs are met. METHODS From March until May 2019, 33 persons with type 2 diabetes from three periurban municipalities of the department of Cochabamba participated in this study. The concept mapping methodology by Trochim, a highly structured qualitative brainstorming method, was used to generate and structure a broad range of perspectives on what the participants considered instrumental for their health. RESULTS The brainstorming resulted in 156 original statements condensed into 72 conceptually different needs and resources, structured under nine conceptual clusters and four action domains. These domains illustrated with vital needs were: (1) self-management with use of plants and the possibility to measure sugar levels periodically; (2) healthcare providers with the need to trust and receive a uniform diagnosis and treatment plan; (3) health system with opportune access to care and (4) community with community participation in health and safety, including removal of stray dogs. CONCLUSIONS This study identifies mostly contextual factors like low literacy levels, linguistic problems in care, the need to articulate people's worldview including traditional use of natural remedies with the Bolivian health system and the lack of expertise on type 2 diabetes by primary health care providers. Understanding the needs and structuring them in different areas wherein action is required serves as a foundation for the planning and evaluation of an integrated people centred care program for people with type 2 diabetes. This participative method serves as a tool to implement the often theoretical concept of integrated people centred health care in health policy and program development.

Abstract
Diabetic ketoacidosis (DKA) is an acute complication of diabetes mellitus that can be associated with increased morbidity and mortality, particularly if it is diagnosed late and not treated appropriately. The management of DKA includes careful clinical evaluation, correction of metabolic abnormalities with intravenous fluids, insulin and electrolyte replacement with frequent monitoring of the patients' clinical and laboratory findings and also identification and treatment of the precipitating condition. There are special populations where features, management and outcome may differ from the usual patient with diabetes. Data on management of DKA in such special populations such as chronic kidney disease and pregnancy are sparse and recommendations are based mainly on small case series and expert opinion. Clinicians need to recognize and manage euglycaemic DKA in patients prescribed sodium-glucose cotransporter inhibitors. DKA is particularly a major health concern due to high rates of hospital admissions and mortality in resource-limited settings due to financial constraints, limiting the adequate provision of insulin and access to health care systems, and dysfunctional health systems. We review the challenges of diagnosis and management of DKA in these specific groups and provide recommendations on optimal patient care.

African Cuisine-Centered Insulin Therapy: Expert Opinion on the Management of Hyperglycaemia in Adult Patients with Type 2 Diabetes Mellitus. Diabetes Ther 2021; 12:37-54. [PMID: 33169346 PMCID: PMC7843662 DOI: 10.1007/s13300-020-00958-z] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/27/2020] [Accepted: 10/23/2020] [Indexed: 12/17/2022] Open
Abstract
The prevalence of diabetes in sub-Saharan Africa (SSA) is growing rapidly, and a steadily increasing number of adults are estimated to be living with type 2 diabetes mellitus (T2DM). Insulin therapy is the treatment of choice in patients who present with severe hyperglycaemia and in most of those who do not achieve target goals on oral hypoglycaemic agents. Initiating treatment with the appropriate type of insulin based on the meal patterns and lifestyle of the individual patient is a strategy that is more likely than others to improve glycaemic control and adherence. African cuisine typically has a high carbohydrate load. Given these predominantly carbohydrate-rich food habits, it is essential to modify this dietary pattern whilst at the same time ensuring that insulin therapy is initiated, titrated and maintained in a timely manner, as needed to suit the patient's habits. To date, there are no published clinical guidelines to guide practitioners and patients on tailoring insulin to match the high carbohydrate content in African cuisine. To address this gap, we have reviewed current insulin therapy practices and propose a patient-centric guide to insulin therapy based on African cuisine. A literature search was conducted for studies published in English up to November 2019 that focused on the choice of insulin and its dosing in relation to African foods. All articles extracted were reviewed by an expert group. The recommendation of the expert group was that basal-bolus and premix insulin regimens are best suited to manage post-meal glycaemia in African cuisine. The timing and constituents of the meal, portion sizes, glycaemic load and glycaemic index of meals should be considered when choosing the type of insulin and insulin regimen. Assessment of individual preferences and comorbidities should be prioritised and form an integral part of diabetes management.

A systematic analysis on prevalence and sub-regional distribution of undiagnosed diabetes mellitus among adults in African countries. J Diabetes Metab Disord 2020; 19:1931-1941. [PMID: 33553047 PMCID: PMC7843872 DOI: 10.1007/s40200-020-00635-9] [Citation(s) in RCA: 13] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/23/2020] [Accepted: 09/13/2020] [Indexed: 12/13/2022]
Abstract
BACKGROUND Despite the high prevalence of diabetes in Africa, the extent of undiagnosed diabetes in the region is still poorly understood. This systematic review and meta-analysis was designed to determine the pooled prevalence of undiagnosed diabetes mellitus among adults in Africa. METHODS We conducted a systematic desk review and electronic web-based search of PubMed, Google Scholar, EMBASE, and the World Health Organization's Hinari portal (which includes the SCOPUS, African Index Medicus, and African Journals Online databases), identifying peer-reviewed research studies on the prevalence of undiagnosed diabetes among adult individuals using pre-defined quality and inclusion criteria. We ran our search from June 1, 2018 to Jun 14, 2020. We extracted relevant data and presented descriptive summaries of the studies in tabular form. The I2 test was used to assess heterogeneity across studies. A random effects model was used to estimate the pooled prevalence of undiagnosed diabetes mellitus at a 95% confidence interval (CI). Funnel plot asymmetry and Egger's tests were used to check for publication bias. The final effect size was determined by applying a trim and fill analysis in a random-effects model. RESULTS Our search identified 1442 studies amongst which 23 articles were eligible for inclusion in the final meta-analysis. The average pooled prevalence of undiagnosed diabetes mellitus among adults was 3.85 (95% CI: 3.10-4.60). The pooled prevalence of undiagnosed diabetes mellitus based on geographic location was 4.43 (95% CI: 3.12-5.74) in Eastern Africa; 4.72 (95% CI: 2.64-6.80) in Western Africa; 4.27 (95% CI: 1.77-6.76) in Northern Africa and 1.46 (95%CI: 0.57-2.34) in southern Africa respectively. CONCLUSION Our findings indicate a high prevalence of undiagnosed diabetes in Africa and suggest that it may be more prevalent in Western Africa than the rest of the regions. Given the high levels of undiagnosed diabetes in the Africa region, more attention should be paid to incorporating diabetes screening and treatment services into existing diabetes related programs to reduce the prevalence of undiagnosed cases.

Abstract
BACKGROUND Young people with type 1 diabetes in low-and-middle income countries face many challenges in accessing care, with various essential supplies needed for survival and long-term health.
AIM To study insulin delivery devices and glycated haemoglobin (HbA1c) testing.
METHODS A survey was conducted in 2019 of leading diabetes centres in 41 countries supported by the Life for a Child Program. The survey covered numerous aspects concerning availability and costs at all levels of the health system, local usage patterns and attitudes, obstacles, and other aspects.
RESULTS Thirty-seven countries returned the survey (90.2% response rate). Key findings included: Syringe use was most common (83.1%), followed by insulin pens (16.7%) and pumps (0.2%). 48.6% of public health systems did not provide syringes, even with a co-payment. Use of suboptimal syringe/needle combinations was common. Needles were generally reused in almost all countries (94.3%, n = 35). Aside from donated supplies, there was variable access to HbA1c testing within public health facilities, and, when available, patients often had to cover the cost. Provision was further compromised by numerous problems including stock-outs, and challenges with understanding the test, equipment maintenance, and refrigeration.
CONCLUSION Large gaps exist for adequate access to appropriate insulin delivery devices and HbA1c testing. Public health systems in low-and-middle income countries should increase affordable provision. There are also needs for specific health professional training and diabetes education; elimination of customs duties and taxes; development of inexpensive, robust HbA1c testing methods that do not require refrigeration of testing supplies; differential pricing schemes; and other solutions.

Costs and outcomes of "intermediate" vs "minimal" care for youth-onset type 1 diabetes in six countries. Pediatr Diabetes 2020; 21:628-636.

Abstract
OBJECTIVE Data are needed to demonstrate that providing an "intermediate" level of type 1 diabetes (T1D) care is cost-effective compared to "minimal" care in less-resourced countries. We studied these care scenarios in six countries. METHODS We modeled the complications/costs/mortality/healthy life years (HLYs) associated with "intermediate" care including two blood glucose tests/day (mean HbA1c 9.0% [75 mmol/mol]) in three lower-gross domestic product (GDP) countries (Mali, Tanzania, Pakistan), or three tests/day (mean HbA1c 8.5% [69 mmol/mol]) in three higher-GDP countries (Bolivia, Sri Lanka, Azerbaijan); and compared findings to "minimal" care (mean HbA1c 12.5% [113 mmol/mol]). A discrete time Markov illness-death model with age and calendar-year-dependent transition probabilities was developed, with inputs of 30 years of complications and Standardized Mortality Rate data from the youth cohort in the Pittsburgh Epidemiology of Diabetes Complications Study, background mortality, and costs determined from international and local prices. RESULTS Cumulative 30 years incidences of complications were much lower for "intermediate care" than "minimal care", for example, for renal failure incidence was 68.1% (HbA1c 12.5%) compared to 3.9% (9%) and 2.4% (8.5%). For Mali, Tanzania, Pakistan, Bolivia, Sri Lanka, and Azerbaijan, 30 years survival was 50.1%/52.7%/76.7%/72.5%/82.8%/89.2% for "intermediate" and 8.5%/10.1%/39.4%/25.8%/45.5%/62.1% for "minimal" care, respectively. The cost of a HLY gained as a % GDP/capita was 141.1%/110.0%/52.3%/41.8%/17.0%/15.6%, respectively. CONCLUSIONS Marked reductions in complications rates and mortality are achievable with "intermediate" T1D care achieving mean clinic HbA1c of 8.5% to 9% (69-75 mmol/mol). This is also "very cost-effective" in four of six countries according to the WHO "Fair Choices" approach which costs HLYs gained against GDP/capita.

Abstract
Background Africa is experiencing a rapid increase in morbidity and mortality related to diabetes mellitus (DM). Contemporary data are needed to guide efforts to improve prevention and treatment for microvascular complications in children and adolescents in Africa. This study was conducted to assess prevalence of diabetic microvascular complications in northwestern Tanzania, including nephropathy, retinopathy, and neuropathy, as well as associated risk factors. Objectives 1) To determine the prevalence of microvascular complications and the overlap of nephropathy, retinopathy and neuropathy and 2) to determine factors associated with the development of microvascular complications. Methods This cross-sectional study included 155 children and adolescents with DM consecutively attending all three health centers providing diabetes care for children in the Mwanza region of Tanzania. Participants were examined for microvascular complications and possible risk factors. Results Fifty-one of 155 participants (age: 5-19 years) had diabetic nephropathy (32.9%), 16 had diabetic retinopathy (10.3%), and 21 had diabetic neuropathy (13.6%). Risk factors for development of a microvascular complication included age, duration of DM, and poor glycemic control. Of the participants, 107 had poor levels of glycemic control (69%) with HbA1C levels >10%. Conclusion The prevalence of microvascular complications, especially that of nephropathy, was disturbingly high. Risk factors for microvascular complications were similar to other studies from Africa and included poor glycemic control, older age, and longer duration of DM. Innovative, locally appropriate systems for optimizing glycemic control are urgently needed.

Abstract
Objectives To explore availability, prices and affordability of essential medicines for diabetes and hypertension treatment in private pharmacies in three provinces of Zambia. Methods A cross-sectional survey was conducted in 99 pharmacies across three Zambian provinces. Methods were based on a standardized methodology by the World Health Organization and Health Action International. Availability was analysed as mean availability per pharmacy and individual medicine. Median prices were compared to international reference prices and differences in price between medicine forms (original brand or generic product) were computed. Affordability was assessed as number of days’ salaries required to purchase a standard treatment course using the absolute poverty line and mean per capita provincial household income as standard. An analysis identifying medicines considered both available and affordable was conducted. Results Two antidiabetics and nine antihypertensives had high-level availability (≥80%) in all provinces; availability levels for the remaining surveyed antidiabetics and antihypertensives were largely found below 50%. Availability further varied markedly across medicines and medicine forms. Prices for most medicines were higher than international reference prices and great price variations were found between pharmacies, medicines and medicine forms. Compared to original brand products, purchase of generics was associated with price savings for patients between 21.54% and 96.47%. No medicine was affordable against the absolute poverty line and only between four and eleven using mean per capita provincial incomes. Seven generics in Copperbelt/Lusaka and two in Central province were highly available and affordable. Conclusions The study showed that the majority of surveyed antidiabetic and antihypertensive medicines was inadequately available (<80%). In addition, most prices were higher than their international reference prices and that treatment with these medicines was largely unaffordable against the set affordability thresholds. Underlying reasons for the findings should be explored as a basis for targeted policy initiatives.

Abstract
AIMS Global governments have committed to achieve Universal Health Coverage (UHC), ensuring access to quality and affordable healthcare for all. This is fundamental for those with type 1 diabetes mellitus, who require daily access to both insulin and blood glucose test strips to survive. This group risks being left behind by global initiatives that fail to consider these particular needs. METHODS A questionnaire was distributed to key informants in 37 less-resourced countries. Seven high-income countries were also included for comparison. We drew on a WHO framework developed to assess progress towards UHC to create scales on three dimensions: population covered, services provided and direct costs. A fourth dimension, availability, was added. Results were grouped into six patterns and visually displayed with radar graphs. RESULTS 65% of the less-resourced national health systems provided insulin, with medians of 67% for service provision (equating to Human Regular and NPH), 55% direct costs covered, and 75% availability. Test strips were only provided in 14% of the less-resourced systems, with medians 42% (less than two strips per day), 76%, and 88% respectively. Six patterns of provision were identified. Progress correlated with income level, yet some low-income countries are achieving provision for insulin and test strips for those enrolled in health insurance schemes. CONCLUSION No less-resourced country had even near-complete coverage for insulin, and coverage was worse for test strips. This study demonstrates the utility of this framework which could be developed as a means of tracking progress in meeting the needs of people with diabetes.

Abstract
Diabetes is a chronic non-communicable disease (NCD) presenting growing health and economic burdens in sub-Saharan Africa (SSA). Diabetes is unique due to its cross-cutting nature, impacting multiple organ systems and increasing the risk for other communicable and non-communicable diseases. Unfortunately, the quality of care for diabetes in SSA is poor, largely due to a weak disease management framework and fragmented health systems in most sub-Saharan African countries. We argue that by synergizing disease-specific vertical programs with system-specific horizontal programs through an integrated disease-system diagonal approach, we can improve access, quality, and safety of diabetes care programs while also supporting other chronic diseases. We recommend utilizing the six World Health Organization (WHO) health system building blocks - 1) leadership and governance, 2) financing, 3) health workforce, 4) health information systems, 5) supply chains, and 6) service delivery - as a framework to design a diagonal approach with a focus on health system strengthening and integration to implement and scale quality diabetes care. We discuss the successes and challenges of this approach, outline opportunities for future care programming and research, and highlight how this approach can lead to the improvement in the quality of care for diabetes and other chronic diseases across SSA.

Abstract
OBJECTIVES Verbal autopsy (VA) is a useful tool to ascertain cause of death where no other mechanisms exist. We aimed to assess the utility of VA data to ascertain deaths due to uncontrolled hyperglycaemia and to develop a weighted score (WS) to specifically identify cases. Cases were identified by a study or site physician with training in diabetes. These diagnoses were also compared with diagnoses produced by a standard computer algorithm (InterVA-4). SETTING This study was done using VA data from the Health and Demographic Survey sites in Agincourt in rural South Africa. Validation of the WS was done using VA data from Karonga in Malawi. PARTICIPANTS All deaths from ages 1 to 49 years between 1992 and 2015 and between 2002 and 2016 from Agincourt and Karonga, respectively. There were 8699 relevant deaths in Agincourt and 1663 in Karonga. RESULTS Of the Agincourt deaths, there were 77 study physician classified cases and 58 computer algorithm classified cases. Agreement between study physician classified cases and computer algorithm classified cases was poor (Cohen's kappa 0.14). Our WS produced a receiver operator curve with area under the curve of 0.952 (95% CI 0.920 to 0.985). However, positive predictive value (PPV) was below 50% when the WS was applied to the development set and the score was dominated by the necessity for a premortem diagnosis of diabetes. Independent validation showed the WS performed reasonably against site physician classified cases with sensitivity of 86%, specificity of 99%, PPV of 60% and negative predictive value of 99%. CONCLUSION Our results suggest that widely used VA methodologies may be missing deaths due to uncontrolled hyperglycaemia. Our WS may offer improved ability to detect deaths due to uncontrolled hyperglycaemia in large populations studies where no other means exist.

Abstract
Introduction There is an increasing commitment in the African Region towards diabetes care, following acknowledgement that it is an important public health issue which needs to be addressed in order to improve population health. We conducted a situational analysis of diabetes care in Guinea Bissau in order to identify the main issues faced in the management of the disease in this country. Methods The study design was qualitative and data collection was done using semi directive interviews and focus groups with participants involved in primary diabetes care and management in Guinea Bissau (health care professionals, non-governmental organization staff, traditional healers) and patients. The data was analyzed using the five-phase approach of the thematic analysis framework. Results The major themes identified included: the lack of specialists and properly trained healthcare personnel; no standardized care protocol for diagnosis, treatment, follow up and proper management for diabetic patients; resources poor primary health care settings; no validated epidemiological dataset on prevalence and the lack of awareness about diabetes (in general population and also in medical staff). Conclusion This first situational analysis can serve as a baseline to develop an action plan to address the main issues identified.

Glob Health Action 2019; 12:1605704. [PMID: 31116677 PMCID: PMC6534215 DOI: 10.1080/16549716.2019.1605704] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 11/12/2022] Open
Abstract
Background: The Base of the Pyramid (BoP) project is a public–private partnership initiated by Novo Nordisk that aims to facilitate access to diabetes care for people at the base of the economic pyramid in low- and middle-income countries (LMICs). In Kenya, the BoP, through a partnership model, aims to strengthen five pillars of diabetes care: increased awareness of diabetes; early diagnosis of diabetes; access to quality care by trained professionals; stable and affordable insulin supply; and improved self-management through patient education. Objectives: This study evaluates the extent to which BoP Kenya is scalable and sustainable, whether stakeholders share in its value, and whether BoP Kenya has improved access to diabetes care. Method: The Rapid Assessment Protocol for Insulin Access (RAPIA), an approach developed to provide a broad situational analysis of diabetes care, was used to examine health infrastructure and diabetes care pathways in Kenya. At the national level, the RAPIA was applied in a SWOT analysis of the BoP through in-depth interviews with key stakeholders. At individual and county health system levels, RAPIA was adapted to explore the impact of the BoP on access to diabetes care through a comparison of an intervention and control county. Results: The BoP was implemented in 28 of 47 counties in Kenya. Meru, a county where BoP was implemented, had 35 of 62 facilities (56%) participating in the BoP. Of the five pillars of the BoP, most notable progress was made in achieving the fourth (stable and affordable insulin supply). A price ceiling of 500KSh (US$5) per vial of insulin was established in the intervention county, with greater fluctuation and stock-outs in the non-intervention county. Despite reduced insulin costs, many patients with diabetes could not afford the additive expenses of monitoring, medicines, and travel. Less progress was made over the other pillars, which also faced challenges to sustainability and scalability. Conclusion: In the context of the rising prevalence of non-communicable diseases in LMICs, cross-sector approaches to improving access to care are increasingly needed. Public–private partnerships such as the BoP are necessary but not sufficient to ensure access to health care for people with diabetes at the base of the economic pyramid in Kenya.

Abstract
Introduction Globally, one in two people needing insulin lack access. High prices and poor availability are thought to be key contributors to poor insulin access. However, few studies have assessed the availability, price and affordability of different insulin types in low-income and middle-income countries in a systematic way. Methods In 2016, 15 insulin price and availability surveys were undertaken (using an adaptation of the WHO/Health Action International medicine price and availability measurement methodology) in Brazil, China (Hubei and Shaanxi Provinces), Ethiopia, Ghana, India (Haryana and Madhya Pradesh States), Indonesia, Jordan, Kenya, Kyrgyzstan, Mali, Pakistan, Russia (Kazan Province) and Uganda. Data were collected in three sectors (public, private pharmacies and private hospitals/clinics) in three regions per survey. Insulin prices were standardised to 10 mL 100 IU/mL in US dollars ($). Data were also collected for four comparator medicines. Results Mean availability was higher for human (55%–80%) versus analogue insulins (55%–63%), but only short-acting human insulin reached 80% availability (public sector). Median government procurement prices were $5 (human insulins) and $33 (long-acting analogues). In all three sectors, median patient prices were $9 for human insulins. Median patient prices for analogues varied between the public sector ($34) and the two private sectors ($44). Vials were cheaper than pens and cartridges. Biosimilars, when available, were mostly cheaper than originators. A low-income person had to work 4 and 7 days to buy 10 mL human and analogue insulin, respectively. For isophane human insulin, only three countries meet the WHO target of 80% availability of affordable essential medicines for non-communicable diseases in any sector. Conclusion Improving insulin availability and affordability needs to be addressed through national and global actions, including prioritising the supply of more affordable human insulin, increasing competition through the use of lower priced quality-assured biosimilars, negotiating lower prices from manufacturers and improving distribution systems.

Abstract
Diabetes mellitus is an increasing public health problem in sub-Saharan Africa with a substantial socioeconomic burden. Although laboratory medicine has been recognized as one of the six key public health functions, there are still gaps in strengthening of laboratory services in developing countries. In the last decades, a lot of progress has been made in the diagnostic field of infectious diseases, whereas the diagnosis of noncommunicable diseases is still insufficient and uneven. This article analyses the challenges encountered in diagnosing and monitoring of diabetes mellitus in sub-Saharan Africa and explores new alternative diagnostic tools.

Abstract
The management of type 1 diabetes (T1DM) includes setting up organised follow-up clinics. A programme for establishing such clinics in Uganda commenced in 2009. The clinics were established along the chronic care model and were integrated into the health structure of other chronic diseases. Web-based electronic medical records were utilised to establish a centralised registry. All children with diabetes below 18 years of age were encouraged to enrol into the programme by attending the nearest established T1DM clinic. At the commencement of the programme, there were 178 patients with T1DM receiving care in various health facilities but without organised follow-up T1DM clinics. These patients were subsequently enrolled into the programme and as of June 30, 2018, the programme had a total of 32 clinics with 1187 children; 3 with neonatal diabetes. Challenges encountered included difficulties in timely diagnosis, failure to provide adequate care in the remote rural areas and failure to achieve pre-defined glycated haemoglobin (HbA1c) goals. Despite these challenges, this observational study demonstrates that healthcare delivery for T1DM organised along the chronic care model and supported by web-based electronic medical records is achievable and provides care that is sustainable. Addressing the encountered challenges should result in improved outcomes for T1DM.

Abstract
Background As Mozambique faces a double burden of diseases, with a rise of Non Communicable Diseases (NCD) superimposed to uncontrolled communicable diseases (CD), routine disease surveillance system does not include NCD. The objectives of our study were to i) upgrade of the current surveillance system by adapting the data collection tools to NCD; ii) describe the occurrence and profile of selected NCD using these data collection tools. Methods Workshops were implemented in a first referral urban hospital of Mozambique to train clinical staff, administrative workers and nurses on NCD surveillance, as well as select conditions to be prioritized. Based on the WHO Global Action Plan and Brazaville Declaration for NCD prevention and control, we selected arterial hypertension, diabetes, stroke, chronic respiratory diseases, mental illness and cancers. Data collection tools used for CD were changed to include age, gender, outcome and visit type. Between February/2014 and January/2015 we collected data at an urban hospital in Mozambique’s capital. Results Over 12 months 92,018 new patients were assisted in this hospital. Data was missing or diagnosis was unreadable in 2637 (2.9%) thus only 89,381 were used for analysis; of these 6423 (median age 27 years; 58.4% female) had at least one selected NCD as their primary diagnosis: arterial hypertension (2397;37.31%), mental illness (1497;23.30%), asthma (1495;23.28%), diabetes (628;9.78%), stroke (299;4.66%), chronic obstructive pulmonary disease 61 (0.95%) and cancers 46 (0.72%). Emergency transfers were needed for 76 patients (1.2%), mainly due to hypertensive emergencies (31; 40.8%) and stroke (18;23.7%). Twenty-four patients died at entry points (0.3%); 10 of them had hypertensive emergencies. Conclusion Changes in existing surveillance tools for communicable diseases provided important data on the burden and outcomes of the selected NCD helping to identify priority areas for training and health care improvement. This information can be used to design the local NCD clinics and to strengthen the health information system in resource-limited settings in a progressive and sustainable way.

Abstract
Optimal care for children and adolescents with type 1 diabetes is well described in guidelines, such as those of the International Society for Pediatric and Adolescent Diabetes. High-income countries can usually provide this, but the cost of this care is generally prohibitive for lower-income countries. Indeed, in most of these countries, very little care is provided by government health systems, resulting in high mortality, and high complications rates in those who do survive. As lower-income countries work toward establishing guidelines-based care, it is helpful to describe the levels of care that are potentially affordable, cost-effective, and result in substantially improved clinical outcomes. We have developed a levels of care concept with three tiers: "minimal care," "intermediate care," and "comprehensive (guidelines-based) care." Each tier contains levels, which describe insulin and blood glucose monitoring regimens, requirements for hemoglobin A1c (HbA1c) testing, complications screening, diabetes education, and multidisciplinary care. The literature provides various examples at each tier, including from countries where the life for a child and the changing diabetes in children programs have assisted local diabetes centres to introduce intermediate care. Intra-clinic mean HbA1c levels range from 12.0% to 14.0% (108-130 mmol/mol) for the most basic level of minimal care, 8.0% to 9.5% (64-80 mmol/mol) for intermediate care, and 6.9% to 8.5% (52-69 mmol/mol) for comprehensive care. Countries with sufficient resources should provide comprehensive care, working to ensure that it is accessible by all in need, and that resulting HbA1c levels correspond with international recommendations. All other countries should provide Intermediate care, while working toward the provision of comprehensive care.

Abstract
A rational design approach is proposed for a multifunctional enzyme reagent for point-of-care diagnostics. The biomaterial reduces downstream isolation steps and eliminates immobilization coupling chemicals for integration in a diagnostic platform. Fusion constructs combined the central functional assay protein (e.g. monomeric sarcosine oxidase, mSOx, horseradish peroxidase, HRP), a visualizing protein (e.g. mCherry) and an in-built immobilization peptide (e.g. R5). Monitoring protein expression in E.coli was facilitated by following the increase in mCherry fluorescence, which could be matched to a color card, indicating when good protein expression has occurred. The R5 peptide (SSKKSGSYSGSKGSKRRIL) provided inbuilt affinity for silica and an immobilization capability for a silica based diagnostic, without requiring additional chemical coupling reagents. Silica particles extracted from beach sand were used to collect protein from crude protein extract with 85-95% selective uptake. The silica immobilized R5 proteins were stable for more than 2 months at room temperature. The Km for the silica-R52-mCh-mSOx-R5-6H was 16.5 ± 0.9 mM (compared with 16.5 ± 0.4 mM, 16.3 ± 0.3 mM, and 16.1 ± 0.4 mM for R52-mCh-mSOx-R5-6H, mSOx-R5-6H and mSOx-6H respectively in solution). The use of the "silica-enzymes" in sarcosine and peroxide assays was shown, and a design using particle sedimentation through the sample was examined. Using shadowgraphy and particle image velocimetry the particle trajectory through the sample was mapped and an hourglass design with a narrow waist shown to give good control of particle position. The hourglass biosensor was demonstrated for sarcosine assay in the clinically useful range of 2.5-10 μM in both a dynamic and end point measurement regime.

[PMID: 30072234 DOI: 10.1016/s2213-8587(18)30074-3] [Citation(s) in RCA: 47] [Impact Index Per Article: 7.8] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/20/2017] [Revised: 02/13/2018] [Accepted: 02/20/2018] [Indexed: 12/23/2022]
Abstract
Blood glucose meters and test strips for self-monitoring of blood glucose (SMBG) are often inaccessible to, and infrequently used by, people with diabetes in countries with limited resources for health care. Supplies for measuring blood glucose can also be scarce in health facilities, despite being needed in a myriad of clinical settings at all levels of the health system. Numerous studies and international guidelines emphasise the value of SMBG in diabetes care, particularly in people with type 1 diabetes. In this Review, we assess global access to blood glucose meters and test strips, collating published information on cost, availability, system accuracy, competitive bidding, technological trends, and non-financial barriers. We also provide new information on global market share data and prices, taxes and tariffs, and product availability. Blood glucose meters and test strips should be viewed similarly to essential medicines, with issues of access prioritised by relevant international agencies. Efforts are needed to reduce tariffs and taxes and to create unified global system accuracy requirements and accountable post-marketing evaluations. Preferential pricing arrangements, pooled procurement, and best-purchasing practices could help to lower direct costs. SMBG supplies should also be included in national health insurance schemes. Enhanced diabetes education of health professionals and patients is crucial to ensure effective use of SMBG. Finally, as technology advances for people who can afford new interstitial fluid glucose monitoring systems, blood glucose meters and test strips must remain available and become more affordable in low-resource settings.

Abstract
BACKGROUND Access to essential medicines in pediatric endocrinology and diabetes is limited in resource-limited countries. The World Health Organization (WHO) maintains two non-binding lists of essential medicines (EMLs) which are often used as a template for developing national EMLs. METHODS We compared a previously published master list of medicines for pediatric endocrinology and diabetes with the WHO EMLs and national EMLs for countries within the WHO African region. To better understand actual access to medicines by patients, we focused on diabetes and surveyed pediatric endocrinologists from 5 countries and assessed availability and true cost for insulin and glucagon. RESULTS Most medicines that are essential in pediatric endocrinology and diabetes were included in the national EMLs. However, essential medicines, such as fludrocortisone, were present in less than 30% of the national EMLs despite being recommended by the WHO. Pediatric endocrinologists from the 5 focus countries reported significant variation in terms of availability and public access to insulin, as well as differences between urban and rural areas. Except for Botswana, glucagon was rarely available. There was no significant relationship between Gross National Income and the number of medicines included in the national EMLs. CONCLUSIONS Governments in resource-limited countries could take further steps to improve EMLs and access to medicines such as improved collaboration between health authorities, the pharmaceutical industry, patient groups, health professionals, and capacity-building programs such as Paediatric Endocrinology Training Centres for Africa.

Abstract
Background Nepal is facing an increasing burden of diabetes and relies almost entirely on insulin imported through India. Methods We employed a modified version of the WHO/Health Action International standard survey to assess insulin availability and prices, along with qualitative interviews with insulin retailers (pharmacists) and wholesalers in the Kathmandu Valley, Nepal. Results The mean availability of the two human insulins listed on the 2011 Nepal Essential Medicine List were 14.3% and 42.85% in the surveyed private- and public-sector pharmacies, respectively, compared with the WHO target of 80% availability. The median consumer price of human insulin cartridges, analogue insulin cartridges and pens was, respectively, 2.1, 4.6 and 5.3 times that of human insulin vials (US$5.54). The insulin cartridges made in India were less expensive (p<0.001) than those made elsewhere. The lowest-paid worker would need to spend between 3 and 17 days' wages to purchase a monthly insulin supply out of pocket. Conclusion Insulin access is limited in Kathmandu owing to low availability and the highly unaffordable price. Insulin access could improve with the government exploring additional suppliers, pooling insulin tenders, auditing insulin utilization and developing independent prescribing guidelines. Furthermore, there is a need to educate physicians and develop a consensus statement on insulin initiation to curb the growing analogue use and promote rational use.

Abstract
BACKGROUND Sub-Saharan Africa continues to face the highest rate of mortality from diabetes in the world due to limited access to quality diabetes care. We assessed the quality of diabetes care in a rural diabetes clinic in western Kenya. METHODS To provide a comprehensive assessment, a set of clinical outcomes, process, and structure metrics were evaluated to assess the quality of diabetes care provided in the outpatient clinic at Webuye District Hospital. The primary clinical outcome measures were the change in HbA1c and point of care blood glucose. In assessing process metrics, the primary measure was the percentage of patients who were lost to follow up. The structure metrics were assessed by evaluating different facets of the operation of the clinic and their accordance with the International Diabetes Federation (IDF) guidelines. RESULTS A total of 524 patients were enrolled into the diabetes clinic during the predefined period of evaluation. The overall clinic population demonstrated a statistically significant reduction in HbA1c and point of care blood glucose at all time points of evaluation after baseline. Patients had a mean baseline HbA1C of 10.2% which decreased to 8.4% amongst the patients who remained in care after 18 months. In terms of process measures, 38 patients (7.3%) were characterized as being lost to follow up as they missed clinic visits for more than 6 months. Through the assessment of structural metrics, the clinic met at least the minimal standards of care for 14 out of the 19 domains recommended by the IDF. CONCLUSION This analysis illustrates the gains made in various elements of diabetes care quality which can be used by other programs to guide diabetes care scale up across the region.

Abstract
PURPOSE OF REVIEW The purpose of this review is to highlight the key issues with regard to the value, affordability, and availability of diabetes treatments. RECENT FINDINGS Many of the medicines needed to manage diabetes are available as generics and, if purchased appropriately, can be made affordable to many individuals and systems. With new treatments for diabetes, additional costs to individuals and systems need to be assessed in terms of added clinical benefit and financial impact. As healthcare finances are limited, increased spending on diabetes medicines means fewer resources for other areas of diabetes care or for the population as a whole. This increased expenditure is driven by rising prevalence as well as the cost of newer treatments. With an increasing burden of disease and changing patterns of medicines in the market, we stress the need to focus attention on ensuring access for individuals to essential medicines. Universal health care offers unique opportunity to address the issue of access to medicines and the wider issues surrounding access to diabetes care, but this will require concerted action bringing together governments, civil society and the private sector.

Abstract
BACKGROUND There is a paucity of evidence on access to services for mental health and psychosocial support for conflict-affected populations in low- and middle-income countries. In the Republic of Georgia, rates of utilization of mental health services among internally displaced people with mental disorders are low. We set out to identify the health system barriers leading to this treatment gap. METHODS We used rapid appraisal methods (collection and triangulation of multiple data sources) to investigate barriers to accessing mental health care services among adult IDPs in Georgia. Data collection included review of existing policy documents and other published data, as well as semi-structured interviews with 29 key informants including policy makers, NGO staff, health professionals and patients. RESULTS The following factors emerged as important barriers affecting access to mental health care services among IDPs in Georgia: inadequate insurance coverage of mental disorders and poor identification and referral systems, underfunding, shortage of human resources, poor information systems, patient out-of-pocket payments and stigmatization. CONCLUSION While rapid appraisal methods cannot control for potential biases or achieve representativeness, triangulation supports internal validity and reliability of the data collected, allowing data to be used to inform health care interventions. The appropriateness and potential effectiveness of policy interventions such as insurance coverage of a wider range of mental disorders, integration of services for these at the primary health care level, and community-based approaches in this context should be explored.

Int J Epidemiol 2018; 47:887-898.

Abstract
BACKGROUND In high-income settings, body mass index (BMI) and measures of central adiposity, such as waist-to-hip ratio (WHR) are associated with cardiometabolic risk, but evidence from low-income settings, particularly sub-Saharan Africa (SSA), is limited. We assessed whether there are differences between central and general adiposity in their associations with fasting glucose, diabetes, systolic and diastolic blood pressures and hypertension, and whether these associations differ with gender or rural/urban setting in Malawi. METHODS We used data from a population-based study of 27 880 Malawian adults aged ≥18 years, from both rural and urban areas. We used age-standardized z-scores of the means of BMI and WHR to directly compare their associations with glycaemic and blood pressure outcomes. RESULTS Mean fasting glucose and blood pressure values and odds of hypertension increased linearly across fifths of BMI and WHR, with stronger associations with BMI. For both BMI and WHR, the associations with outcomes were stronger in urban versus rural residents. The association with diabetes was stronger in women than men, whereas for blood-pressure related outcomes a stronger association was seen in men. CONCLUSIONS BMI is more strongly associated with cardiometabolic risk in SSA, and might be a more useful measure than WHR, in this population. The greater positive association of adiposity with cardiometabolic outcomes in urban residents (where rates of overweight/obesity are already high) highlights the particular importance of addressing obesity within urban SSA populations.

Abstract
Background Effective health systems are needed to care for the coming surge of diabetics in sub-Saharan Africa (SSA). Objective We conducted a systematic review of literature to determine the capacity of SSA health systems to manage diabetes. Methodology We used three different databases (Embase, Scopus, and PubMed) to search for studies, published from 2004 to 2017, on diabetes care in SSA. Results Fifty-five articles met the inclusion criteria, covering the different aspects related to diabetes care such as availability of drugs and diagnostic tools, the capacity of healthcare workers, and the integration of diabetes care into HIV and TB platforms. Conclusion Although chronic care health systems in SSA have developed significantly in the last decade, the capacity for managing diabetes remains in its infancy. We identified pilot projects to enhance these capacities. The scale-up of these pilot interventions and the integration of diabetes care into existing robust chronic disease platforms may be a feasible approach to begin to tackle the upcoming pandemic in diabetes. Nonetheless, much more work needs to be done to address the health system-wide deficiencies in diabetes care. More research is also needed to determine how to integrate diabetes care into the healthcare system in SSA.
