Association of unmet discharge needs on readmission or mortality among acute respiratory failure survivors during the COVID-19 pandemic: The Addressing Post-Intensive Care Syndrome (APICS-COVID) multicenter prospective cohort study

Background: Survivors of acute respiratory failure (ARF) often face long-term impairments known as Post-Intensive Care Syndrome. These impairments, coupled with fragmented healthcare, contribute to high rates of readmission and mortality. The COVID-19 pandemic challenged healthcare systems, providing an important opportunity to evaluate healthcare fragmentation before and during the pandemic. Methods: From December 2020 to July 2022, this prospective multicenter study (APICS-COVID) enrolled ARF...

Visual outcomes and headache in intracranial hypertension following cerebral venous sinus thrombosis: A retrospective cohort study

Intracranial hypertension is a frequent complication of cerebral venous sinus thrombosis (CVT), posing a risk for permanent visual impairment. However, long-term visual outcomes have not been systematically assessed using objective neuro-ophthalmic measures. We retrospectively evaluated consecutive adults presenting to a single-center tertiary intracranial hypertension clinic between 2019 and 2025 with intracranial hypertension following CVT. Visual outcomes were assessed using best-corrected vi...

Protocol for investigating the association between Helicobacter pylori exposure, antigen-specific serological responses, and resistant versus non-resistant hypertension in a South African cohort

Background: Hypertension is a leading contributor to cardiovascular morbidity and mortality, with poor control in low- and middle-income countries. Helicobacter pylori (H. pylori) has been associated with hypertension through inflammatory, endothelial, metabolic and immune pathways, but data from sub-Saharan Africa, particularly in resistant hypertension, are limited. Methods: This cross-sectional observational study will enrol 200 adults aged ≥18 at a tertiary academic hospital in Cape Town, So...

HIF-1α/PPAR-γ/SIRT1 axis drives astrocyte senescence and regulates endothelial function via GDNF/NRTN in diabetic retinopathy

Background: Diabetic retinopathy (DR) is a leading cause of blindness in working-age populations. Astrocyte senescence is highly prevalent in DR, but the underlying regulatory mechanism remains unclear. This study aims to investigate the role of the HIF-1α/PPAR-γ/SIRT1 axis in regulating retinal astrocyte senescence and endothelial function in DR. Methods: Mouse retinal astrocytes were exposed to high glucose (30 mM) to mimic diabetic conditions. Senescence was evaluated by β-galactosidase stain...

Cardiovascular disease risk prediction models for people living with HIV in Sub-Saharan Africa: A scoping review protocol

Background: The landscape of Human Immunodeficiency Virus (HIV) care has dramatically shifted with the advent of effective antiretroviral therapy (ART), transforming HIV from a rapidly fatal illness into a chronic, manageable disease. This success, however, has unveiled new challenges, primarily the increased prevalence of non-AIDS-related comorbidities, with non-communicable diseases (NCDs) such as cardiovascular disease (CVD) emerging as a critical concern for people living with HIV (PLWH). CV...

Development of a village health worker care model to reduce cardiovascular risk in areas of armed conflict: Qualitative results from a participatory planning process in Myanmar

Cardiovascular disease (CVD) is the leading cause of death in Myanmar, but care models are lacking to deliver evidence-based treatments to reduce CVD risks in areas of armed conflict. Village health workers (VHWs) play a key role in bridging communities and clinics, but their role in CVD prevention and management in conflict-affected settings has not been clearly defined. This study aimed to describe the system for CVD care and to elicit perspectives on how VHWs might contribute to a village-bas...

Calibration of a fully closed-loop lumped-parameter cardiovascular model with baroreflex in response to induced central hypovolemia

Calibration of cardiovascular models is essential to their clinical utility. We provide a full description of the calibration of a non-linear, dynamic model using global optimisation methods. Specifically, we consider an experimental cohort response in a closed-loop, baro-regulated cardiovascular model, in the setting of induced central hypovolemia.We propose a framework for simplifying calibration of dynamic, regulated models. We perform global sensitivity analysis and orthogonality analysis of...

Commonly expressed key driver genes in the pathogenesis of viral and non-viral liver cancer

Background: Hepatocellular carcinoma (HCC) is a common and lethal liver cancer primarily associated with viral infections like hepatitis B virus (HBV) and hepatitis C virus (HCV), as well as non-viral causes. Understanding the molecular mechanisms of these subtypes is essential for identifying potential biomarkers and therapeutic targets. Methods: In this study, an integrated bioinformatics approach was used to analyze publicly available datasets related to HBV-associated, HCV-associated, and no...

Male breast cancer in Northern Tanzania: Clinicopathology and predictors of two-year survival (2016–2022)

Background: Male breast cancer (BC) is rare, accounting to approximately 1% of all breast cancers worldwide. Patients often present with advanced disease, contributing to poor outcomes. This study aimed to estimate two-year overall survival (OS) and identify clinicopathological and health-system–related predictors of survival among men with breast cancer treated at Kilimanjaro Christian Medical Centre (KCMC). Methods: A retrospective cohort study was conducted among 55 histologically confirmed m...

Uncovering the immune microenvironmental atlas of breast cancer molecular subtypes based on single-cell transcriptomics

Breast cancer progression is closely linked to immune cells within the tumor microenvironment (TME), but the immune landscape differences across HER2-positive (HER2+), triple-negative (TNBC), and ER-positive (ER+) subtypes have yet to be systematically characterized. In this study, we characterized immune landscape differences across HER2-positive (HER2+), triple-negative (TNBC), and ER-positive (ER+) breast cancers using single-cell RNA sequencing data, focusing on T cells, macrophages, and B c...

Transcriptome- and methylome-wide association studies prioritized lung cancer genes in East Asian populations

The relationship between gene expression, DNA methylation, and lung cancer remains elusive in East Asian (EAS) populations. Transcriptome- and methylome-wide association studies (TWAS/MWAS) help uncover gene–trait associations by integrating multi-omics data, yet models trained mainly on European references limit cross-population generalizability. To address this, we developed EAS-specific gene expression and DNA methylation prediction models using whole-blood data from over 800 and 4,300 indivi...

Development, validation, and testing of an agriculture support exoskeleton in adjunct to conventional physiotherapy for farm labourers with chronic low back pain: A two-phase, mixed-methods, quasi-experimental pilot study protocol

Background: Low back pain (LBP) affects 619 million people globally, with projections reaching 843 million by 2050. Farm labourers exhibit markedly higher prevalence than the general population, with lifetime (70–85%), 12-month (15–45%), and point (approximately 30%) prevalences driven by sustained trunk flexion, repetitive manual handling, and limited access to ergonomic or rehabilitative interventions. While conventional physiotherapy is the cornerstone of chronic LBP (CLBP) management, its ef...
