BACKGROUND: High-risk emergency department (ED) revisit is considered an important quality indicator that may reflect an increase in complications and medical burden. However, because of its multidimensional and highly complex nature, this factor has not been comprehensively investigated. This study aimed to predict high-risk ED revisit with a machine-learning (ML) approach. METHODS: This 3-year retrospective cohort study assessed adult patients between January 2019 and December 2021 from National Taiwan University Hospital Hsin-Chu Branch with high-risk ED revisit, defined as hospital or intensive care unit admission after ED return within 72 hours...

BACKGROUND: This study investigated morphological, cardiovascular and neuromuscular profiles among asymptomatic sedentary men performing the Islamic prayer (Salaah). This study emphasised the need for an inquiry into unique sedentary populations who perform Islamic prayer as physical activity. METHODS: An experimental study was conducted among male participants (n=20). Resting heart rate (RHR), resting systolic blood pressure (SBP), resting diastolic blood pressure (DBP), body mass index (BMI) and percentage body fat (BF%) were measured before a timed Salaah simulation activity...

BACKGROUND: Although bronchiectasis is reported to be associated with cardiovascular disease, evidence for an association with cardiovascular events (CVEs) is lacking. METHODS: A territory-wide retrospective cohort study was conducted in Hong Kong involving all patients who had bronchiectasis diagnosed in public hospitals and clinics between 1 January 1993 and 31 December 2017 were included. Patients were allocated to be exacerbator or non-exacerbator group based on hospitalzied bronchiecsis history and CVEs over the next 5 years determined...

INTRODUCTION: Supervised exercise training is among the first-line therapies for patients with peripheral artery disease (PAD). Current recommendations for exercise include guidance focusing on claudication pain, programme and session duration, and frequency. However, no guidance is offered regarding exercise training intensity. This study aims to compare the effects of 12-week-long supervised walking exercise training (high-intensity interval training (HIIT) vs moderate-intensity exercise (MOD)) in patients with chronic symptomatic PAD...

OBJECTIVE: Patients with congenital heart disease (CHD) have an increased cancer risk. The aim of this study was to determine cancer-related mortality in CHD patients compared with non-CHD controls, compare ages at cancer diagnosis and death, and explore the most fatal cancer diagnoses. DESIGN: Registry-based cohort study. SETTING AND PARTICIPANTS: CHD patients born between 1970 and 2017 were identified using Swedish Health Registers. Each was matched by birth year and sex with 10 non-CHD controls...

We present the case of an elderly man with a history of diastolic congestive heart failure, severe aortic stenosis and atrial fibrillation, who presented with fatigue, weakness, coffee ground emesis and black tarry stool. Haemoglobin was 68 g/L. Lactate dehydrogenase was elevated at 1038. Evaluation by cardiology and gastroenterology specialists revealed reflux oesophagitis and a mild hiatal hernia on oesophagogastroduodenoscopy, normal colonoscopy and small bowel series without obstruction. Capsule endoscopy identified angiodysplasia in the small intestine...

OBJECTIVE: To investigate risks of multiple adverse outcomes associated with use of antipsychotics in people with dementia. DESIGN: Population based matched cohort study. SETTING: Linked primary care, hospital and mortality data from Clinical Practice Research Datalink (CPRD), England. POPULATION: Adults (≥50 years) with a diagnosis of dementia between 1 January 1998 and 31 May 2018 (n=173 910, 63.0% women)...

OBJECTIVES: To examine how the lifetime risks of atrial fibrillation and of complications after atrial fibrillation changed over time. DESIGN: Danish, nationwide, population based cohort study. SETTING: Population of Denmark from 1 January 2000 to 31 December 2022. PARTICIPANTS: 3.5 million individuals (51.7% women and 48.3% men) who did not have atrial fibrillation at 45 years of age or older were followed up until incident atrial fibrillation, migration, death, or end of follow-up, whichever came first...

INTRODUCTION: Nigeria is committed to reducing industrial trans- fatty acids (iTFA) from the food supply, but the potential health gains, costs and cost-effectiveness are unknown. METHODS: The effect on ischaemic heart disease (IHD) burden, costs and cost-effectiveness of a mandatory iTFA limit (≤2% of all fats) for foods in Nigeria were estimated using Markov cohort models. Data on demographics, IHD epidemiology and trans- fatty acid intake were derived from the 2019 Global Burden of Disease Study...

BACKGROUND: Globally, cardiovascular disease (CVD) remains the leading cause of death, warranting effective management and prevention measures. Risk prediction tools are indispensable for directing primary and secondary prevention strategies for CVD and are critical for estimating CVD risk. Machine learning (ML) methodologies have experienced significant advancements across numerous practical domains in recent years. Several ML and statistical models predicting CVD time-to-event outcomes have been developed...

OBJECTIVE: To investigate the risk of cardiovascular events associated with commonly used dual and triple therapies of evogliptin, a recently introduced dipeptidyl peptidase-4 inhibitor (DPP4i), for managing type 2 diabetes in routine clinical practice. DESIGN: A retrospective cohort study. SETTING: Korean Health Insurance Review and Assessment database. PARTICIPANTS: Patients who initiated metformin-based dual therapy and metformin+sulfonylurea-based triple therapy in South Korea from 2014 to 2018...

OBJECTIVE: Estimate the incremental costs and benefits of scaling up hypertension care in adults in 24 select countries, using three different systolic blood pressure (SBP) treatment cut-off points-≥140, ≥150 and ≥160 mm Hg. INTERVENTION: Strengthening the hypertension care cascade compared with status quo levels, with pharmacological treatment administered at different cut-points depending on the scenario. TARGET POPULATION: Adults aged 30+ in 24 low-income and middle-income countries spanning all world regions...

BACKGROUND: Autism spectrum disorder (ASD) is one of the most complex neurodevelopmental disorders. It affects almost all human physiological systems. Individuals with ASD often display dysregulation in their autonomic nervous system (ANS), which may elicit differing effects across age groups. Also, studying the ANS missed several important parameters related to ANS. Studying the ANS is crucial in developing adaptive behavioural strategies and maintaining communication abilities and social behaviours...

Artificial intelligence (AI) has developed greatly and is now at the centre of technological advancements. Current and recent military conflicts have highlighted the evolving complexity of warfare with rapid technological change at the heart of it. AI aims to understand and design systems that show signs of intelligence and are able to learn by deriving knowledge from data. There have been multiple AI-related developments in the medical field in areas such as diagnostics, triage, wearable technology and training with direct translations that may benefit UK Defence healthcare...

Catecholamine surge and haemodynamic derangements are normally expected during the surgery for pheochromocytoma and benign functioning adrenal tumours. This male patient in his 50s underwent radical nephrectomy for renal cell carcinoma. The patient had no comorbidities. Three hours into the surgery, during electrocauterisation of the upper pole of the kidney, the patient's blood pressure unexpectedly spiked to 180/110 mm Hg, which was immediately followed by a decrease in heart rate to 35-38 beats/min...
