Harmful use of alcohol causes more deaths in Sub-Saharan Africa than in any other region. In Tanzania, where alcohol use disorders rates are twice the overall African average, harmful alcohol consumption is a public health concern. Given the lack of a contemporary overview of the alcohol policy landscape, we conducted a mixed-methods review of key alcohol-related policies, implementers, and initiatives in Tanzania.

Article Synopsis
  • Methamphetamine (MA) use is prevalent in south east Nigeria, with a reported prevalence of 21.8% among surveyed adolescents and adults, primarily driven by depression and commonly administered through inhalation.
  • The study utilized a descriptive cross-sectional survey with 371 respondents and analyzed data using various statistical methods to identify factors associated with MA use.
  • Key control measures identified included self-control, parental monitoring, drug education, and legal oversight, while users were characterized by aggressive behavior and living off-campus, which correlated with lower MA use likelihood.

Introduction: Equitable inclusion of low-income and middle-income country (LMIC) researchers and women in research authorship is a priority. A review of progress in addressing WHO-identified priorities provided an opportunity to examine the geographical and gender distribution of authorship in herpes simplex virus type-2 (HSV-2) research.

Methods: Publications addressing five areas prioritised in a WHO workshop and published between 2000 and 2020 were identified.

Introduction: Reviewing and updating research priorities is essential to assess progress and to ensure optimal allocation of financial and human resources in research. In 2001, WHO held a research priority setting workshop for herpes simplex virus type 2 (HSV-2) research in low-income and middle-income countries (LMICs). This study aimed to describe progress between 2000 and 2020 in three of the five key research priority areas outlined in the workshop: HSV-2/HIV interactions, HSV-2 control measures and HSV-2 mathematical modelling.

Introduction: Low-income and middle-income countries (LMICs) have a high burden of herpes simplex virus type 2 (HSV-2) infection, which has been strongly associated with HIV. In 2001, the WHO hosted a workshop to set research priorities for HSV-2 in LMICs. Periodic re-evaluation of research priorities is essential to ensure effective allocation of resources.

Heavy alcohol use amongst adolescent boys is a major public health concern in many countries. It is associated with a range of negative physical and mental health outcomes and predicts alcohol-related problems in adulthood. In Kilimanjaro Region, adolescent boys' alcohol use is widespread, and higher than other regions in Tanzania.

Background: Recruitment in sexual health research is challenging. This study explores the potential of a Consent for Contact system (C4C) - generic consent for research contact - to improve participant recruitment and engagement in sexual health research. Our objectives were to understand patient and staff understanding of research, their views on a separate C4C system, and their preferences for its acceptability in a sexual health clinic setting.

Introduction: Previous studies have reported numerous clinico-pathologic risk factors associated with increased risk of leaked repair following omental patch for perforated peptic ulcer disease (PPUD). This study aimed to analyze the risk factors associated with leaked repair of omental patch and document the management and outcome of established cases of leaked repair in a resource-poor setting.

Methods: This is a multicenter cross-sectional study of leaked repair after omental patch of PPUD between January 2016 to December 2022.

HIV testing among HIV-exposed infants (HEI) in Malawi is below global targets and, affected by low utilisation of health services after birth. We conducted a mixed methods evaluation of the implementation of services for early infant diagnosis (EID) of HIV against national guidelines in Blantyre, Malawi, to inform the development of strategies to improve EID services uptake. We estimated coverage of HEI enrolment in HIV care and HIV testing at 6 weeks through a retrospective data review.

Introduction: Poor mental health in adolescence is associated with mental, physical and social problems in later life. Adolescence is, therefore, a critical time for promoting mental well-being and preventing mental illness, particularly in sub-Saharan Africa, where adolescents are exposed to a multitude of risk factors for poor mental health. This review aimed to map the current use, effectiveness and cultural sensitivity of promotive/preventive adolescent mental health interventions in the region.

Background: In sub-Saharan Africa, the origins of asthma and high prevalence of abnormal lung function remain unclear. In high-income countries (HICs), associations between birth measurements and childhood asthma and lung function highlight the importance of antenatal and early life factors in the aetiology of asthma and abnormal lung function in children. We present here the first study in sub-Saharan Africa to relate birth characteristics to both childhood respiratory symptoms and lung function.

Issues: Globally, adolescent drinking is a major public health concern. Alcohol measurements are influenced by local consumption practices, patterns and perceptions of alcohol-related harm. This is the first review to examine what tools are used to measure alcohol consumption, or screen for or assess harmful use in African adolescents, and how these tools take into account the local context.

Background: Although 1 billion people live in informal (slum) settlements, the consequences for respiratory health of living in these settlements remain largely unknown. This study investigated whether children living in an informal settlement in Nairobi, Kenya are at increased risk of asthma symptoms.

Methods: Children attending schools in Mukuru (an informal settlement in Nairobi) and a more affluent area (Buruburu) were compared.

Introduction: The incidence of major trauma in older people is increasing. Frailty is likely to be a factor that influences the outcomes of trauma. We conducted a systematic review aiming to investigate whether frailty affects major trauma outcomes in older people and whether it is more predictive than age.

Early infant diagnosis of HIV (EID-HIV) is key to reducing paediatric HIV mortality. Traditional approaches for diagnosing HIV in exposed infants are usually unable to optimally contribute to EID. Point-of-care testing such as Cepheid Xpert HIV-1 Qual assay-1 (XPertHIV) are available and could improve EID-HIV in resource constrained and high HIV burden contexts.

Background: Over 500 million people live with chronic respiratory diseases globally and approximately 4 million of these, mostly from the low- and middle-income countries including sub-Saharan Africa, die prematurely every year. Despite high CRD morbidity and mortality, only very few studies describe CRDs and little is known about the economic, social and psychological dimensions of living with CRDs in sub-Saharan Africa. We aimed to gain an in-depth understanding of the social, livelihood and psychological dimensions of living with CRD to inform management of CRDs in Sudan and Tanzania.

Background: Research integrity is central to good research practice yet it is under-researched in global health.

Aim: To identify and explore factors which promote or constrain adherence to research integrity principles in global health research partnerships, specifically at a UK higher education institution (HEI) and its low-to-middle-income country (LMIC) partners.

Methods: Qualitative study using key informant interviews among researchers at a HEI and a number of its LMIC partners exploring their understanding of the principles of research integrity and experience of its implementation in relation to research.

Article Synopsis
  • * A qualitative study in Kenya, Malawi, Sudan, Tanzania, and Uganda involved interviews with 109 healthcare workers and policy stakeholders to understand the barriers to diagnosing and managing CRD effectively.
  • * Findings revealed that poor data collection, inadequate funding for essential services, and a neglect of CRD in healthcare policies lead to underdiagnosis and underreporting, creating a cycle of invisibility that hampers effective health responses.
