Enhancing the value of mortality data for health systems: adding Circumstances Of Mortality CATegories (COMCATs) to deaths investigated by verbal autopsy.

Half of the world's deaths and their causes pass unrecorded by routine registration systems, particularly in low- and middle-income countries. Verbal autopsy (VA) collects information on medical signs, symptoms and circumstances from witnesses of a death that is used to assign likely medical causes. To further contextualise information on mortality, understanding underlying determinants, such as logistics, barriers to service utilisation and health systems responses, is important for health planning.

Investigation of physical and functional impairments experienced by people with active tuberculosis infection: A feasibility pilot study.

Background: Tuberculosis (TB) remains a significant healthcare problem. Understanding physical and functional impairments that patients with active TB present with at the time of diagnosis and how these impairments change over time while they receive anti-TB therapy is important in developing appropriate rehabilitation programmes to optimise patients' recovery.

Objectives: The aim of this study was to assess the acceptability, implementation and practicality of conducting a prospective, observational and longitudinal trial to describe physical and functional impairments of patients with active TB.

Completeness of obstetric referral letters/notes from subdistrict to district level in three rural districts in Greater Accra region of Ghana: an implementation research using mixed methods.

Objective: To assess the completeness of obstetric referral letters/notes at the district level of healthcare.

Design: An implementation research within three districts in Greater Accra region using mixed methods. During baseline and intervention phases, referral processes for all obstetric referrals from lower level facilities seen at the district hospitals were documented including indications for referrals, availability and completeness of referral notes/forms.

Prevalence and Associations, by Age Group, of IPV Among AGYW in Rural South Africa.

The prevalence of intimate partner violence (IPV) is alarmingly high among South African adolescent girls and young women (AGYW). Limited data exist exploring how IPV prevalence and its risk factors differ by age. Study data were from the baseline visit of HPTN 068, a randomized controlled trial (RCT) conducted from 2011 to 2015 in Mpumalanga, South Africa.

Assessing trauma care health systems in low- and middle-income countries, a protocol for a systematic literature review and narrative synthesis.

Background: Trauma represents a major global health problem projected to increase in importance over the next decade. The majority of deaths occur in low- and middle-income countries (LMICs) where survival rates are lower than their high-income country (HIC) counterparts. Health system level changes in care for injured patients have been attributed to significant improvements in care quality and outcomes in HIC settings.

HIV treatment cascade for older adults in rural South Africa.

Objectives: The HIV treatment cascade is a powerful framework for understanding progress from initial diagnosis to successful treatment. Data sources for cascades vary and often are based on clinical cohorts, population cohorts linked to clinics, or self-reported information. We use both biomarkers and self-reported data from a large population-based cohort of older South Africans to establish the first HIV cascade for this growing segment of the HIV-positive population and compare results using the different data sources.

External injuries, trauma and avoidable deaths in Agincourt, South Africa: a retrospective observational and qualitative study.

Objective: Injury burden is highest in low-income and middle-income countries. To reduce avoidable deaths, it is necessary to identify health system deficiencies preventing timely, quality care. We developed criteria to use verbal autopsy (VA) data to identify avoidable deaths and associated health system deficiencies.

An integrated approach to processing WHO-2016 verbal autopsy data: the InterVA-5 model.

Background: Verbal autopsy is an increasingly important methodology for assigning causes to otherwise uncertified deaths, which amount to around 50% of global mortality and cause much uncertainty for health planning. The World Health Organization sets international standards for the structure of verbal autopsy interviews and for cause categories that can reasonably be derived from verbal autopsy data. In addition, computer models are needed to efficiently process large quantities of verbal autopsy interviews to assign causes of death in a standardised manner.

A comparison of all-cause and cause-specific mortality by household socioeconomic status across seven INDEPTH network health and demographic surveillance systems in sub-Saharan Africa.

Background: Understanding socioeconomic disparities in all-cause and cause-specific mortality can help inform prevention and treatment strategies.

Objectives: To quantify cause-specific mortality rates by socioeconomic status across seven health and demographic surveillance systems (HDSS) in five countries (Ethiopia, Kenya, Malawi, Mozambique, and Nigeria) in the INDEPTH Network in sub-Saharan Africa.

Methods: We linked demographic residence data with household survey data containing living standards and education information we used to create a poverty index.

Pharmacokinetic Profile of Prolonged-Release Tacrolimus When Administered via Nasogastric Tube in De Novo Liver Transplantation: A Sub-Study of the DIAMOND Trial.

BACKGROUND For patients unable to swallow during the immediate post-transplant period, immunosuppressant therapy may be initiated by administering prolonged-release tacrolimus as a suspension via a nasogastric tube. MATERIAL AND METHODS In this sub-study of the DIAMOND randomized controlled trial of prolonged-release tacrolimus in de novo liver transplant recipients, we investigated the pharmacokinetic (PK) profile of prolonged-release tacrolimus when administered via nasogastric tube immediately post-transplant. PK analyses were performed on whole-blood samples collected on Day 1 of tacrolimus administration and on Day 3 post-transplantation.

Needs must: living donor liver transplantation from an HIV-positive mother to her HIV-negative child in Johannesburg, South Africa.

The world's first living donor liver transplant from an HIV-positive mother to her HIV-negative child, performed by our team in Johannesburg, South Africa (SA) in 2017, was necessitated by disease profile and health system challenges. In our country, we have a major shortage of donor organs, which compels us to consider innovative solutions to save lives. Simultaneously, the transition of the HIV pandemic, from a death sentence to a chronic illness with excellent survival on treatment required us to rethink our policies regarding HIV infection and living donor liver transplantation .

Institutionalising the evaluation function: A South African study of impartiality, use and cost.

Purpose: This article explores the implications of outsourcing the evaluation function in South Africa, a context where there is a mismatch between evaluation supply and demand. It unpacks the tradeoffs between internal and external evaluation, and challenges some commonly held assumptions about both.

Approach: Based on experiences as an internal evaluator, external evaluator, evaluation manager, and building evaluation capacity, the author explores how each role changes when evaluation is a scarce skill, and looks at implications outsourcing has for both the organization, and the evaluation.

Clinical Practice Recommendations on the Routine Use of Eversense, the First Long-Term Implantable Continuous Glucose Monitoring System.

The use of real-time continuous glucose monitoring (rtCGM) systems has proved to positively impact the management of type 1 diabetes with the potential to lower HbA1c, reduce frequency and time spent in hypoglycemia, and lower glycemic variability. Nevertheless, the acceptance of rtCGM remains below expectations and the dropout rate within the first year has been reported to be 27%. Besides financial reasons due to limited reimbursement, reasons include the need for frequent sensor replacement, the discomfort of wearing a sensor, the presence of adverse skin reactions, or privacy.

Relationship between children's cognitions and later educational progress in rural South Africa: a longitudinal study.

Background: Children in low-income and middle-income countries (LMICs) who remain in school have better health and employment outcomes. South Africa, like many LMICs, has a secondary school completion rate under 50%, leaving room for improvement if we can identify factors that affect educational attainment. This is the first longitudinal study to examine the effects of childhood mental health and cognitions on educational outcomes in LMIC.

International Consensus on Guiding Recommendations for Management of Patients with Nonsteroidal Antiinflammatory Drugs Induced Gastropathy-ICON-G.

Introduction: Nonsteroidal anti-inflammatory drugs (NSAIDs), one of the most commonly used medications worldwide, are frequently associated with gastrointestinal adverse events. Primary care physicians often face the challenge of achieving adequate pain relief with NSAIDs, while keeping their adverse events to a minimum. This is especially true when long-term use of NSAIDs is required such as in patients with osteoarthritis and rheumatoid arthritis.

Friendships Among Young South African Women, Sexual Behaviours and Connections to Sexual Partners (HPTN 068).

Friends could be influential on young women's sexual health via influences on sexual behaviours and as connections to sexual partners, but are understudied in sub-Saharan Africa. We cross-sectionally surveyed 2326 13-20 year-old young women eligible for grades 8-11 in rural South Africa about their sexual behaviour and up to three sexual partners. Participants each described five specific but unidentified friends and the relationships between them in an 'egocentric' network analysis design.

A rare case of concomitant bilateral nipple and vulval condyloma accuminatum.

In this case study, we have presented a rare case of concomitant human papillomavirus condylomata lesions of both breast nipples and giant vulval warts in an HIV-positive woman on antiretroviral therapy. The woman underwent successful surgical excision and reconstruction for both breast nipple condylomata and vulval warts. Histology of the excised breast nipple and vulval tissue confirmed low-risk human papillomavirus infection.

What is the minimum number of specialist anaesthetists needed in low-income and middle-income countries?

Introduction: The number of specialist anaesthetists in most low-income and middle-income countries is below what is needed to provide a safe quality anaesthesia service. There are no estimates of the optimal number; therefore, we estimated the minimum density of specialist anaesthetists to achieve a reasonable standard of healthcare as indicated by the maternal mortality ratio (MMR).

Methods: Utilising existing country-level data of the number of physician anaesthesia providers (PAPs), MMR and Human Development Index (HDI), we developed best-fit curves to describe the relationship between MMR and PAPs, controlling for HDI.

International survey on growth indices and impacting factors in children with food allergies.

Background: Elimination diets required for the management of food allergies increase the risk for poor growth in children. Currently, no worldwide data exist on this topic and limited published data exist on the impact of atopic comorbidity, type of allergy and foods eliminated on growth. We therefore set out to perform a worldwide survey on growth and impacting factors in food allergic children.

Opportunities and challenges for evidence-informed HIV-noncommunicable disease integrated care policies and programs: lessons from Malawi, South Africa, Swaziland and Kenya.

Introduction: Countries in sub-Saharan Africa (SSA) are recognizing the growing dual burden of HIV and noncommunicable diseases (NCDs). This article explores the availability, implementation processes, opportunities and challenges for policies and programs for HIV/NCD integration in four SSA countries: Malawi, Kenya, South Africa and Swaziland.

Methods: We conducted a cross-sectional analysis of current policies and programs relating to HIV/NCD care integration from January to April 2017 using document review and expert opinions.

Alternative assembly processes from trait-mediated co-evolution in mutualistic communities.

Ecological and evolutionary dynamics observed in mutualistic communities can be shaped by several mechanisms, including ecological interactions and their co-evolutionary consequences. Here we explore how intra and interspecific competition, together with mutualistic interactions, can affect community assembly through their effects on adaptive diversification and the emergence of biodiversity. To capture both ecological and evolutionary processes simultaneously, we used the adaptive dynamics approach based on a Lotka-Volterra framework and simulated the ecological dynamics of populations as well as the evolutionary dynamics of phenotypic traits.

Cross-sectional relationship between haemoglobin concentration and measures of physical and cognitive function in an older rural South African population.

Background: Age cohort differences in haemoglobin concentrations and associations with physical and cognitive performance among populations of lower income and middle-income countries have not previously been described. We examined the association between these factors among older men and women in rural South Africa.

Methods: We analysed cross-sectional data from a population-based study of rural South African men and women aged 40 and over (n=4499), with data drawn from questionnaire responses, a cognitive battery, objective physical function tests and blood tests.

HIV and the histopathologist.

The practicing histopathologist is often a forgotten link in the management of HIV patients. This article aims to highlight the unique challenges faced by anatomical pathologists as well as focusing on the valuable contribution they can make to ensure prompt and accurate diagnoses that will ultimately benefit the patient.

Photosensitive disorders in HIV.

Photosensitive disorders are common, affecting up to 5% of HIV-positive patients. HIV itself induces photosensitivity but photoaggravated drug reactions, porphyria cutanea tarda and nutritional disorders such as pellagra are also more common in patients with HIV. In South Africa, actinic lichenoid leukomelanoderma of HIV is a unique photosensitive disorder which is associated with advanced HIV.
