Arryhthmias can afflict any heart, even in the absence of disease. Given that Cardiac Output (CO) is a product of heart rate and stroke volume, the end-result of brady- and tachy-arrhythmias is the same: low CO with symptoms of low-output state. In bradyarrhythmias, myocardial inotropy operates maximally but the product of stroke volume and slow heart rate yields a low CO. In tacharryhthmias, myocardial inotropy is redundant because the product of low stroke volume arising from low Diastolic Filling Time (DFT) and heart rate also yields a low CO. The hallmark of extrasystole is the duplex of symptoms: dizziness followed by palpitation.

Mortality Rates and Forensic Causes after Hip Fracture: A Retrospective Observational Study.
Arch Bone Jt Surg
January 2024
Özel Medicabil Hastanesi, Bursa.
Objectives: Despite the widely recognised high mortality rate among patients with hip fracture, the variation in death rates by gender and cause has been less explored. This study aimed to investigate mortality rates and causes of death in patients who underwent hip fracture surgery, and to compare them with those of the general population. A secondary objective was to compare the results of Internal Fixation versus Arthroplasty in these patients.

Background: Autonomic dysfunction plays an essential role in dementia, however, it is not known whether electrocardiogram autonomic dysfunction-related indicators are associated with the severity of dementia. In this study, we attempted to investigate whether these indicators are correlated in patients with vascular dementia and Alzheimer's disease compared with normal health individuals. For this purpose, we measured and analyzed the predictive value of heart rate deceleration capacity (DC), heart rate deceleration runs (DRs), heart rate acceleration capacity (AC) along with the plasma levels of lipoprotein-associated phospholipase A2 (Lp-PLA2).

Institute of General Practice, Friedrich-Alexander University Erlangen, Nuernberg, Germany.
Objective: HAPpEN aims to implement and evaluate a holistic general practitioner-centered, interdisciplinary obesity management strategy in rural Germany, focusing on feasibility, health outcomes, and economic benefits.
Methods: HAPpEN is a 12-month, pragmatic single-arm, multicenter trial, informed by a formative survey, and initiated in April 2023 with 98 obese participants (body mass index, BMI ≥ 30 kg/m) in Kulmbach, Germany. The program integrates nutritional counseling, physical activity, and behavior change techniques, including smartphone-based self-monitoring.
Prediction of delirium occurrence using machine learning in acute stroke patients in intensive care unit.

Introduction: Delirium, frequently experienced by ischemic stroke patients, is one of the most common neuropsychiatric syndromes reported in the Intensive Care Unit (ICU). Stroke patients with delirium have a high mortality rate and lengthy hospitalization. For these reasons, early diagnosis of delirium in the ICU is critical for better patient prognosis.

Background: Identifying asymptomatic patients with atrial fibrillation (AF) poses a challenge, and their optimal management is less certain, despite similar outcomes to symptomatic AF patients. The 'Atrial fibrillation Better Care' (ABC) pathway has been recently proposed as a holistic or integrated care approach for the comprehensive management of symptomatic patients with AF. We aimed to determine the use of the ABC pathway on clinical outcomes in asymptomatic patients with AF.
