Caregiving experiences, challenges and needs of mothers for their young children who are HIV exposed and uninfected from Worcester, South Africa – A qualitative exploration through the nurturing care …
In high HIV prevalence settings, pregnancy and early childhood can be stressful periods for mothers with HIV, due to fear of HIV transmission, breastfeeding concerns, poor health and socio-economic challenges. Not much is known about how mothers of young children who are HIV exposed and uninfected (HEU) experience caregiving before and beyond the confirmation of their HIV-negative status. Using the Nurturing Care Framework for early childhood dev…
Modelling correlates of adolescent and young people viral suppression pathway in Zambia
This study aimed to look into the correlates of viral suppression in HIV-infected adolescents by utilizing Markov renewal multi-state survival models based on the Bayesian Approach, which use a deterministic posterior approximation. We developed a patient-level viral suppression transition framework to quantify the prognostic factors influencing viral suppression. The results showed that HIV-infected adolescents had higher risk of attaining viral…
“She tells me the HIV is eating my brains”
Despite the successful rollout of antiretroviral therapy (ART) and positive ART outcomes in the Kingdom of Eswatini, adolescents still present poor ART outcomes including low viral load suppression and suboptimal ART adherence. The aim of the study was to explore the perceptions of adolescents living with HIV (ALHIV) on the barriers and facilitators to ART adherence in Eswatini. We conducted a qualitative study using in-depth interviews among 29 …
Caring for a young child who is HIV exposed and whose HIV status is not yet known
Living with HIV can affect mothers' wellbeing, functioning, and experiences of caregiving. Most research about caregiving in the context of HIV comes from studies of dyads where both mother and child are living with HIV. Less is known about how mothers experience caregiving when their children are HIV exposed, but their HIV-status is not yet known. We conducted a scoping review to map out existing evidence on this topic. Systematic database searc…
The prevalence and correlates of common mental disorders among adolescents and young adults in rural South Africa
Depression and anxiety are among the most common mental disorders (CMDs) affecting adolescents and young adults (AYA). CMDs often emerge during adolescence and young adulthood, yet are frequently diagnosed in adulthood. Understanding the burden and correlates of CMDs is essential for informing public mental health interventions. However, limited research incorporates the perspectives of AYA with lived experience of mental health conditions. This …
Structural barriers and facilitators to accessing HIV services for marginalized working populations
Farm workers are vulnerable working populations who face significant inequalities in accessing health services, including those for human immunodeficiency virus (HIV) prevention, treatment and care. This descriptive phenomenological study aimed to explore farm workers’ experiences when accessing HIV services and was conducted in Limpopo province, South Africa. Eighteen in-depth interviews were conducted in four health facilities from two district…
Emergence of highly resistant Candida auris in the United Arab Emirates
Introduction The Centers for Disease Prevention and Control lists Candida auris , given its global emergence, multidrug resistance, high mortality, and persistent transmissions in health care settings as one of five urgent threats. As a new threat, the need for surveillance of C. auris is critical. This is particularly important for a cosmopolitan setting and global hub such as the United Arab Emirates (UAE) where continued introduction and emerg…
Factors associated with high HIV-related stigma among commuter populations in Johannesburg, South Africa
Stigma remains an important barrier to seeking and staying in care among individuals infected with Human Immunodeficiency Virus (HIV). Despite continued widespread information, education and communication campaigns to raise awareness about the infection. The aim of the study was to identify factors related to HIV stigma among a commuter population in the inner-city Johannesburg. A self-administered closed-ended questionnaire was loaded onto perso…
Global, regional, and national burden of neurological disorders, 1990–2016
BACKGROUND: Neurological disorders are increasingly recognised as major causes of death and disability worldwide. The aim of this analysis from the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2016 is to provide the most comprehensive and up-to-date estimates of the global, regional, and national burden from neurological disorders. METHODS: We estimated prevalence, incidence, deaths, and disability-adjusted life-years (DALYs;…
Global, regional, and national age-sex-specific mortality and life expectancy, 1950–2017
BACKGROUND: Assessments of age-specific mortality and life expectancy have been done by the UN Population Division, Department of Economics and Social Affairs (UNPOP), the United States Census Bureau, WHO, and as part of previous iterations of the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD). Previous iterations of the GBD used population estimates from UNPOP, which were not derived in a way that was internally consistent wit…
Global, regional, and national age-sex-specific mortality for 282 causes of death in 195 countries and territories, 1980–2017
BACKGROUND: Global development goals increasingly rely on country-specific estimates for benchmarking a nation's progress. To meet this need, the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2016 estimated global, regional, national, and, for selected locations, subnational cause-specific mortality beginning in the year 1980. Here we report an update to that study, making use of newly available data and improved methods. GBD …
Global, regional, and national comparative risk assessment of 84 behavioural, environmental and occupational, and metabolic risks or clusters of risks for 195 countries and territories, 1990–2017
BackgroundThe Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2017 comparative risk assessment (CRA) is a comprehensive approach to risk factor quantification that offers a useful tool for synthesising evidence on risks and risk–outcome associations. With each annual GBD study, we update the GBD CRA to incorporate improved methods, new risks and risk–outcome pairs, and new data on risk exposure levels and risk–outcome associatio…
Global, regional, and national disability-adjusted life-years (Dalys) for 359 diseases and injuries and healthy life expectancy (Hale) for 195 countries and territories, 1990–2017
BACKGROUND: How long one lives, how many years of life are spent in good and poor health, and how the population's state of health and leading causes of disability change over time all have implications for policy, planning, and provision of services. We comparatively assessed the patterns and trends of healthy life expectancy (HALE), which quantifies the number of years of life expected to be lived in good health, and the complementary measure o…
Measuring progress from 1990 to 2017 and projecting attainment to 2030 of the health-related Sustainable Development Goals for 195 countries and territories
BACKGROUND: Efforts to establish the 2015 baseline and monitor early implementation of the UN Sustainable Development Goals (SDGs) highlight both great potential for and threats to improving health by 2030. To fully deliver on the SDG aim of "leaving no one behind", it is increasingly important to examine the health-related SDGs beyond national-level estimates. As part of the Global Burden of Diseases, Injuries, and Risk Factors Study 2017 (GBD 2…
Global, regional, and national incidence, prevalence, and years lived with disability for 354 diseases and injuries for 195 countries and territories, 1990–2017
BACKGROUND: The Global Burden of Diseases, Injuries, and Risk Factors Study 2017 (GBD 2017) includes a comprehensive assessment of incidence, prevalence, and years lived with disability (YLDs) for 354 causes in 195 countries and territories from 1990 to 2017. Previous GBD studies have shown how the decline of mortality rates from 1990 to 2016 has led to an increase in life expectancy, an ageing global population, and an expansion of the non-fatal…
A roadmap for the implementation of mHealth innovations for image-based diagnostic support in clinical and public-health settings
BACKGROUND: Diagnostic support for clinicians is a domain of application of mHealth technologies with a slow uptake despite promising opportunities, such as image-based clinical support. The absence of a roadmap for the adoption and implementation of these types of applications is a further obstacle. OBJECTIVES: This article provides the groundwork for a roadmap to implement image-based support for clinicians, focusing on how to overcome potentia…
Factors Influencing Delayed Health Care Seeking Among Pulmonary Tuberculosis Suspects in Rural Communities in Ntcheu District, Malawi
