Effect of yoga on musculoskeletal complaints in women during endocrine treatment for breast cancer: protocol of the randomised controlled COBRA trial

Introduction Approximately 40% of women stop endocrine therapy for hormone-receptor-positive breast cancer within the first 5 years of prescribed treatment because of side effects. Musculoskeletal complaints are among the most frequently reported side effects. The Cancer Of the BReast Asanas (COBRA) study examines the effect of an 18-week yoga programme on endocrine therapy-associated musculoskeletal complaints in women with breast cancer. Methods and analysis In total, 140 women will be randomised in a 1:1 ratio to the intervention or waitlist control group. The intervention programme…

Continuation of first-line therapy with radiotherapy for oligoprogression versus early switch to second-line therapy in oligoprogressive hepatocellular carcinoma (CROSS): study protocol of a multicentre, randomised, controlled, open-label, phase III trial

Introduction Treatment options remain limited for patients with advanced hepatocellular carcinoma (HCC) who experience oligoprogression during first-line systemic therapy (FLST), especially given the modest efficacy and restricted availability of second-line systemic therapy (SLST). This trial aims to evaluate whether continuing FLST combined with radiotherapy (RT) to oligoprogressive lesions can improve progression-free survival (PFS) compared with an early switch to SLST in patients with oligoprogressive HCC while maintaining an acceptable safety profile. Methods and analysis The…

HIV self-testing for partners of postpartum women to facilitate HIV pre-exposure prophylaxis and antiretroviral therapy uptake: a protocol to adapt and pilot an intervention via a pilot randomised controlled trial in South Africa

Introduction South African women are vulnerable to HIV acquisition during the postpartum period which can result in perinatal transmission via breastfeeding; many male partners do not know their HIV status. Biomedical approaches to preventing HIV for postpartum women include pre-exposure prophylaxis (PrEP) and antiretroviral treatment for male partners with HIV. Gaps in implementation include low uptake of PrEP among postpartum women and infrequent testing of men who may be motivated to test for HIV to protect the health of their infant. Methods and analysis We will conduct a randomised pilot…

Design Retrospective, multicentre, non-interventional observational cohort study. Setting Region-wide public healthcare system data (primary and secondary care) from Andalusia (Spain), 2016–2022. Participants All adult patients meeting inclusion criteria with a recorded diagnosis of hypercholesterolaemia between 1 January 2016 and 31 December 2022 (n=557 034; 227 834 men and 329 200 women)…

Transcutaneous auricular vagus nerve stimulation for moderate to severe chronic prostatitis/chronic pelvic pain syndrome (TASC-P) in China: study protocol for a randomised controlled trial

Introduction Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) affects around 35%–50% of men during their lifetime. The efficacy of current oral medication for CP/CPPS remains limited. Recent studies demonstrated that vagus nerve stimulation may improve chronic pelvic and abdominal pain. Accordingly, transcutaneous auricular vagus nerve stimulation (taVNS) might represent a promising, non-invasive therapeutic approach for the clinical management of CP/CPPS. Methods and analysis The trial of Transcutaneous Auricular vagus nerve Stimulation for moderate to severe Chronic…

Catering to patients with Parkinsons disease: a survey on self-perceived competence and barriers of speech and language pathologists in Malaysia

Objective Referrals to speech and language pathology are infrequent for people with Parkinson’s disease (PD), despite speech and communication being often affected and greatly impacting their quality of life. This study investigated the knowledge, self-competence and challenges faced by speech and language pathologists (SLPs) in Malaysia when managing PD cases. Design Participants self-administered an online-survey in a cross-sectional study design. The survey consisted of 14 questions on current practices of SLPs with their patients with PD, self-perceived competence when assessing and…

Threats and deprivations as predictors of IPV perpetration: a cross-sectional analysis of a nationally representative sample of Bangladeshi young adults

Purpose Intimate partner violence (IPV) is a major public health concern in Bangladesh, where approximately two-thirds of women report experiencing partner violence and over half of young men admit to perpetrating it. While adverse childhood experiences (ACEs) are among the strongest predictors of IPV, existing research has relied on cumulative ACE scores, overlooking how distinct dimensions of childhood adversity may differentially predict violence. This study examines the relationship between two dimensions of ACEs, threat (eg, exposure to violence) and deprivation (eg, lack of emotional or…

Prediction of ICU length of stay, hospital discharge outcomes and discharge location among ICU-admitted patients diagnosed with viral hepatitis using machine learning: a retrospective cohort study of the MIMIC-IV database

Background Hepatitis, a disease characterised by inflammation of the liver, is a leading global health challenge that contributes to over 1.3 million deaths annually, with hepatitis B and C accounting for many of these fatalities. Intensive care unit (ICU) management of patients is particularly challenging due to the complex clinical care and resource demands. Despite advancements in ICU predictive analytics, limited research has specifically addressed hepatitis patients, creating a gap in optimising care for this population. Methods This study focuses on predicting ICU length of stay (LoS)…

Feasibility of a community-based intervention for the diagnosis and management of hypertension in two rural populations in Kenya and The Gambia: IMPLEMENT-IHCoR feasibility study protocol

Introduction Hypertension is the leading global risk factor for mortality, causing over 10 million deaths annually. In sub-Saharan Africa, hypertension prevalence is high, particularly in rural areas, where it is less likely to be diagnosed, treated or controlled effectively. This results in a high burden of complications, including heart failure, stroke and kidney disease. Community-centred approaches using community health workers (CHWs), risk-based approaches and simplified treatment regimens have shown promise in improving hypertension management. However, there is limited evidence on the…
