Cost-effectiveness of tyrosine kinase inhibitor treatment strategies for chronic myeloid leukemia in South Africa.

Background: The treatment of chronic myeloid leukemia through tyrosine kinase inhibitors (TKIs) has achieved promising efficacy and safety outcomes, however the costs are associated with a substantial economic burden. The objective of this study was to develop a Markov model with a 20-year time horizon to assess the cost effectiveness of TKIs from a public healthcare system perspective in South Africa.

Methods: We constructed a Markov model to compare three strategies in which treatment was initiated with either imatinib, nilotinib, or dasatinib.

A role for qualitative methods in researching Twitter data on a popular science article's communication.

Big Data communication researchers have highlighted the need for qualitative analysis of online science conversations to better understand their meaning. However, a scholarly gap exists in exploring how qualitative methods can be applied to small data regarding micro-bloggers' communications about science articles. While social media attention assists with article dissemination, qualitative research into the associated microblogging practices remains limited.

An assessment of compliance with proposed regulations to restrict on-package marketing of packaged foods to improve nutrition in South Africa.

Background: Ultra-processed products (UPPs), high in sugar, fat and sodium, contribute to increasing burdens of obesity and non-communicable diseases in South Africa (SA). Increased consumption and acceptability of UPPs is driven, in part by aggressive marketing. Front of package labelling laws, particularly warning labels (WLs) coupled with marketing restrictions, have been recommended to improve consumer awareness of unhealthy products, incentivise reformulation and underpin other interventions.

Theoretical impact of a bedside decision-making tool on antibiotic use for suspected neonatal healthcare-associated infection: an observational study.

Background And Objectives: Healthcare-associated infections (HAI) are a leading contributor to morbidity and mortality in hospitalised neonates. Diagnosing neonatal HAI is challenging owing to non-specific symptoms and lack of definitive diagnostic markers, contributing to high rates of inappropriate antibiotic use. This study evaluated the theoretical impact of implementing a bedside tool for decision-making on antibiotic length of therapy (LOT).

An in silico analysis of heart rate impact on wall shear stress hemodynamic parameters in aortic coarctation.

This study examines how heart rate (HR) affects hemodynamics in a South African infant with Coarctation of the Aorta. Computed tomography angiography segments aortic coarctation anatomy; Doppler echocardiography derives inlet flow waveforms. Simulations occur at 100, 120, and 160 beats per minute, representing reduced, resting, and elevated HR levels.

Understanding gender inequities in antimicrobial resistance: role of biology, behaviour and gender norms.

Antimicrobial resistance (AMR) poses a critical public health threat, with gendered implications that are often overlooked. Key drivers of bacterial AMR include the misuse of antibiotics, inadequate water, sanitation and hygiene infrastructure and poor infection control practices. Persistent gender discrimination exacerbates these issues, resulting in disparities in healthcare access and outcomes.

Small intra-tropical long-distance migratory birds track rainy seasons across hemispheres.

The main features of long-distance migration are derived from landbirds breeding in the Northern Hemisphere. Little is known about migration within the tropics, presumably because tropical species typically move opportunistically and over shorter distances. However, such generalizations are weakened by a lack of solid data on spatial, temporal and behavioural patterns of intra-tropical migrations.

Platelet aggregation and thromboelastometry monitoring in women with preeclampsia: a prospective observational study.

Background: Thrombocytopenia affects 12-20% of women with preeclampsia and a low platelet count impairs coagulation. Women with preeclampsia have an increased risk of both cerebral hemorrhage, thromboembolism, and postpartum hemorrhage. Studies of platelet function and coagulation in women with preeclampsia show conflicting results.

Mycobacterium tuberculosis resisters despite HIV exhibit activated T cells and macrophages in their pulmonary alveoli.

Natural resistance to Mycobacterium tuberculosis (Mtb) infection in some people with HIV (PWH) is unexplained. We performed single cell RNA-sequencing of bronchoalveolar lavage cells, unstimulated or ex vivo stimulated with Mtb, for 7 PWH who were TST & IGRA positive (called LTBI) and 6 who were persistently TST & IGRA negative (called resisters). Alveolar macrophages (AM) from resisters displayed a baseline M1 macrophage phenotype while AM from LTBI did not.

Optimising Instrumented Mouthguard Data Analysis: Video Synchronisation Using a Cross-correlation Approach.

Purpose: Head acceleration events (HAEs) are a growing concern in contact sports, prompting two rugby governing bodies to mandate instrumented mouthguards (iMGs). This has resulted in an influx of data imposing financial and time constraints. This study presents two computational methods that leverage a dataset of video-coded match events: cross-correlation synchronisation aligns iMG data to a video recording, by providing playback timestamps for each HAE, enabling analysts to locate them in video footage; and post-synchronisation event matching identifies the coded match event (e.

The trade of illicit cigarettes in Ghana: Insights from a policy synthesis and qualitative study.

The illicit trade of tobacco products trade continues to challenge tobacco control efforts in several African countries, including Ghana. Ghana recently ratified the Framework Convention for Tobacco Control (FCTC) Protocol to Eliminate Illicit Trade in Tobacco Products ('the Protocol'). This Protocol aims to eliminate all kinds of illicit tobacco.

Advances in the awareness of tuberculosis-associated chronic obstructive pulmonary disease.

Tuberculosis (TB) significantly increases the risk of developing chronic obstructive pulmonary disease (COPD), positioning TB-associated COPD (TB-COPD) as a distinct category within the spectrum of respiratory diseases prevalent, especially in low- and middle-income countries. This condition results from the body's immune response to TB, leading to prolonged inflammation and consequent persistent lung damage. Diagnostic approaches, particularly post-bronchodilator spirometry, are vital for identifying airflow obstruction and confirming TB-COPD.

Background: Numerous studies have been conducted on barriers to cervical cancer screening in low resourced settings. Few have however explored the factors that motivate women to make the decision for screening. This study therefore aimed at identifying strategies that could strengthen the utilisation of screening services, with the goal of informing the development of context for enhancing cervical cancer programmes in Gwanda district, Zimbabwe.

Early onset neonatal bloodstream infections in South African hospitals.

Background: Neonatal sepsis is a leading cause of death in low- and middle- income countries (LMIC). Increasing antibiotic resistance in early onset (< 72 h of life) bloodstream infection (EO-BSI) pathogens in LMIC has reduced the effectiveness of the recommended empiric antibiotic regimen (ampicillin plus gentamicin).

Methods: We retrospectively analysed blood culture-confirmed EO-BSI episodes at nine neonatal units from three central and six peripheral hospitals in the Western Cape Province, South Africa between 1 January 2017 and 31 December 2018.

Can a novel computer vision-based framework detect head-on-head impacts during a rugby league tackle?

Background: Head-on-head impacts are a risk factor for concussion, which is a concern for sports. Computer vision frameworks may provide an automated process to identify head-on-head impacts, although this has not been applied or evaluated in rugby.

Methods: This study developed and evaluated a novel computer vision framework to automatically classify head-on-head and non-head-on-head impacts.

Estimating Trends in Cardiovascular Disease Risk for the EXPOSE (Explaining Population Trends in Cardiovascular Risk: A Comparative Analysis of Health Transitions in South Africa and England) Study: Repeated Cross-Sectional Study.

Background: Cardiovascular diseases (CVDs) are the leading cause of death globally. Demographic, behavioral, socioeconomic, health care, and psychosocial variables considered risk factors for CVD are routinely measured in population health surveys, providing opportunities to examine health transitions. Studying the drivers of health transitions in countries where multiple burdens of disease persist (eg, South Africa), compared with countries regarded as models of "epidemiologic transition" (eg, England), can provide knowledge on where best to intervene and direct resources to reduce the disease burden.

"She tells me the HIV is eating my brains": barriers and facilitators to antiretroviral therapy adherence among Eswatini adolescents living with HIV.

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 ALHIV and on ART in Eswatini in December 2023.
