BackgroundThe etiology of pre-eclampsia (PE) is not yet fully understood, though current literature indicates an upregulation of inflammatory mediators produced by the placenta as a potential causal mechanism. Vitamin D is known to have anti-inflammatory properties and there is evidence of an inverse relationship between dietary calcium intake and the incidence of PE. Evidence of the role of vitamin D status and supplementation in the etiology and prevention of PE is reviewed in this article along with identification of research gaps to inform future studies.MethodsWe conducted a structured literature search using MEDLINE electronic databases to identify published studies until February 2015. These sources were retrieved, collected, indexed, and assessed for availability of pregnancy-related data on PE and vitamin D.ResultsSeveral case-control studies and cross-sectional studies have shown an association between vitamin D status and PE, although evidence has been inconsistent. Clinical trials to date have been unable to show an independent effect of vitamin D supplementation in preventing PE.ConclusionsThe included clinical trials do not show an independent effect of vitamin D supplementation in preventing PE; however, issues with dose, timing, and duration of supplementation have not been completely addressed.Electronic supplementary materialThe online version of this article (doi:10.1186/s12884-017-1408-3) contains supplementary material, which is available to authorized users.
IntroductionLipodystrophy is a term used to describe a metabolic complication of fat loss, fat gain, or a combination of fat loss and gain, which is associated with some antiretroviral (ARV) therapies given to HIV-infected individuals. There is limited research on lipodystrophy in low- and middle-income countries, despite accounting for more than 95% of the burden of HIV/AIDS. The objective of this review was to evaluate the prevalence, pathogenesis and prognosis of HIV-related lipoatrophy, lipohypertrophy and mixed syndrome, to inform clinical management in resource-limited settings.MethodsWe conducted a structured literature search using MEDLINE electronic databases. Relevant MeSH terms were used to identify published human studies on HIV and lipoatrophy, lipohypertrophy, or mixed syndrome in low-, low-middle- and upper-middle-income countries through 31 March 2014. The search resulted in 5296 articles; after 1599 studies were excluded (958 reviews, 641 non-human), 3697 studies were extracted for further review. After excluding studies conducted in high-income settings (n=2808), and studies that did not meet inclusion criteria (n=799), 90 studies were included in this review.Results and DiscussionOf the 90 studies included in this review, only six were from low-income countries and eight were from lower middle-income economies. These studies focused on lipodystrophy prevalence, risk factors and side effects of antiretroviral therapy (ART). In most studies, lipodystrophy developed after the first six months of therapy, particularly with the use of stavudine. Lipodystrophy is associated with increased risk of cardiometabolic complications. This is disconcerting and anticipated to increase, given the rapid scale-up of ART worldwide, the increasing number and lifespan of HIV-infected patients on long-term therapy, and the emergence of obesity and non-communicable diseases in settings with extensive HIV burden.ConclusionsLipodystrophy is common in resource-limited settings, and has considerable implications for risk of metabolic diseases, quality of life and adherence. Comprehensive evidence-based interventions are urgently needed to reduce the burden of HIV and lipodystrophy, and inform clinical management in resource-limited settings.
Background The prevalence of hypertension in low‐ and middle‐income countries is rapidly increasing, with most cases undiagnosed and many poorly controlled among those diagnosed. Medication reconciliation studies from high‐income countries have demonstrated a high occurrence of antihypertensive medication errors and a strong association between medication errors and inadequate blood pressure control, but data from low‐ and middle‐income countries are lacking. Methods and Results We conducted a cross‐sectional study from April to October 2018 of adult patients on pharmacologic management for known hypertension at 7 public health facilities in Kweneng East District, Botswana. Our aims included to evaluate the frequency of uncontrolled hypertension, the frequency and type of medication errors causing discrepancies between patient‐reported and prescribed antihypertensive medications, and the association between medication errors and uncontrolled hypertension. Descriptive analyses and multivariable logistic regression were used. The prevalence of uncontrolled hypertension was 55% among 280 enrolled adult patients, and 95 (34%) had ≥1 medication error. The most common errors included patients taking medications incorrectly (11.1%; 31/280), patients omitting medications (7.9%; 22/280), and unfilled prescriptions caused by pharmacy stock outs (7.5%%; 21/280). Uncontrolled hypertension was significantly associated with having ≥1 medication error compared with no errors (adjusted odds ratio, 3.26; 95% CI, 1.75–6.06; P <0.001). Conclusions Medication errors are strongly associated with poor blood pressure control in this setting. Further research is warranted to assess whether medication reconciliation and other low‐cost interventions addressing root causes of medication errors can improve the control of hypertension and other chronic conditions in low‐ and middle‐income countries.
The coronavirus disease 2019 (COVID-19) pandemic has disrupted health systems worldwide, gravely threatening continuity of care for non-communicable diseases (NCDs), particularly in low-resource settings. We describe our efforts to maintain the continuity of care for patients with NCDs in rural western Kenya during the COVID-19 pandemic, using a five-component approach: 1) Protect: protect staff and patients; 2) Preserve: ensure medication availability and clinical services; 3) Promote: conduct health education and screenings for NCDs and COVID-19; 4) Process: collect process indicators and implement iterative quality improvement; and 5) Plan: plan for the future and ensure financial risk protection in the face of a potentially overwhelming health and economic catastrophe. As the pandemic continues to evolve, we must continue to pursue new avenues for improvement and expansion. We anticipate continuing to learn from the evolving local context and our global partners as we proceed with our efforts.
IntroductionAn epidemic of non-communicable diseases (NCDs) in India is fueling a growing demand for primary care and hospitalization services. Difficulties in coordinating inpatient and outpatient care create significant barriers to providing high-quality medical care. In this paper, we describe patient experiences, perceptions, and expectations of doctor-patient relationships in a secondary-level private hospital in Karnataka, India.MethodsWe conducted a cross-sectional, mixed-method needs assessment with surveys and in-depth interviews at Dr. TMA Pai Hospital (TMAPH), a secondary-level, private sector hospital in Karnataka, India. Inclusion criteria included all adults over 18 years old hospitalized at TMAPH in the past year. Patients were consecutively recruited from August 2019-October 2019 and asked to rate aspects of their relationship with their primary care provider (PCP). Descriptive statistics and multivariable logistic regression were used to analyze predictors of the doctor-patient relationship. Patients were interviewed regarding their perceptions of care coordination and doctor-patient relationships. General Thematic Analysis was utilized to analyze qualitative data and develop themes. Quantitative and qualitative findings were then merged to interpret the various dimensions of doctor-patient relationships.ResultsA total of 150 patients (47.3% male) enrolled. Ten patients underwent qualitative interviews. The median patient age was 67 years (IQR 56–76). 112 (74.7%) of patients identified a PCP either at or outside of TMAPH. 89% had diabetes and/or hypertension. Compared to patients without a PCP, having a PCP led to a significantly higher adjusted odds of always spending optimal time with their doctors (aOR 2.7, 95% CI 1.1–6.8, p = 0.04), and always receiving clear instructions on managing their medical conditions (aOR 2.5, 95% CI 1.0–6.1, p = 0.04). The following themes were developed from patient interviews: (1) patients trusted and respected their PCP believing they were receiving high quality care; and (2) despite perceived fragmentation in care, patients spoke favorably of their relationships with their doctors.ConclusionsAmong a sample of recently hospitalized patients, those with a PCP reported more positive doctor-patient relationships, though rates of dissatisfaction with doctors were still high. Further research and strategies are required to optimize continuity of care and doctor-patient relationships across the entire continuum of outpatient and inpatient care.
Background Social and demographic changes in Botswana are resulting in an increased prevalence of cardiovascular disease (CVD). Providers, mostly nurses, in this setting have limited training in managing CVD risk and few opportunities for continued medical education. We aimed to evaluate providers' perceived confidence in managing CVD risk factors and describe management of patients with hypertension at public-sector clinics in a rural district of Botswana. MethodsIn this cross-sectional study, we invited public-sector health-care providers in 11 ambulatory clinics in the Kweneng East district of Botswana to complete an anonymous questionnaire survey. We used descriptive statistics to evaluate providers' confidence in managing CVD risk (a Likert scale from 1 [low confidence] to 5 [high confidence]). We used t tests to compare confidence levels between groups of providers and specific risk factors. Additionally, we interviewed patients and did chart reviews to assess how CVD risk factors were managed in 275 hypertensive patients at seven of the 11 sites surveyed. Uncontrolled hypertension was defined as ≥140/90 mm Hg (or ≥130/80 mm Hg in patients with diabetes) for an average of two blood pressure readings and CVD risk was defined using WHO guidelines. FindingsOf 88 health care providers invited to participate, 44 registered nurses (80%), four family nurse practitioners (7%), and seven doctors (13%) completed the survey. Providers reported feeling significantly more comfortable managing hypertension than they did diabetes (3•73 vs 3•15; p<0•0001) and had lowest confidence with a mean Likert rating of 1•95 (95% CI 1•58-2•31), 2•27 (95% CI 1•93-2•62), and 2•13 (95% CI 1•75-2•51) for prescribing aspirin, statins, and adjusting insulin, respectively. Of the 275 patients with hypertension, 55% (152) had uncontrolled hypertension, and 45% (69) of those with uncontrolled hypertension had no changes to their medications over the course of a year. Of 53 patients who also had diabetes, 51% (27) had uncontrolled disease and an additional 15% (8) had no recent blood glucose check. Of 52 patients with 10-year CVD risk of more than 10%, 55•7% (29) were prescribed aspirin and 15% (8) a statin.Interpretation Public sector health-care providers in rural Botswana have low confidence in managing CVD risk factors. Although reported confidence was higher for management of hypertension than for diabetes, there were significant lapses in management of both diseases. CVD and diabetes account for 22% of all adult deaths in Botswana and it is imperative that training in management of these diseases is improved. To address low provider confidence and gaps in guideline-driven CVD prevention, we plan to implement an integrative training programme for health workers in the Kweneng East district of Botswana.
