Background And Aims: Exploring the effect of different isometric resistance training (IRT) on improving blood pressure, so as to provide important reference for the design of aerobic exercise prescription for IRT to improve blood pressure.
Methods: Forty eight overweight or obese college students with irregular exercise habits were randomly divided into four groups and underwent exercise intervention three times a week for a total of 6 weeks. Cardiovascular changes were evaluated before the first and 18th exercise sessions, as well as 0, 30, and 60 min after exercise.
Results: Heart rate (HR) of equal distance wall squat group (ISG) and whole body equal length exercise group (WIG) increased significantly immediately after exercise, but long-term IRT intervention significantly decreased systolic blood pressure (SBP), diastolic blood pressure (DBP) and mean arterial pressure (MAP) of WIG and ISG, SBP, and MAP of equal grip strength group (IHG), and DBP and MAP of equal curl up group (ICG); In the first exercise, ICG, ISG, and WIG significantly increased SBP and DBP immediately after exercise, ISG significantly increased MAP immediately after exercise, while in the 18th exercise, IHG, ISG, and WIG significantly increased SBP immediately after exercise, ISG significantly increased DBP and MAP immediately after exercise.
Conclusion: IRT is a safe and easy to implement exercise mode. Long-term intervention can effectively control blood pressure, and will not cause excessive cardiovascular pressure response after a single exercise.

Cardiorespiratory fitness, cardiac morphology and function, and cardiovascular risk factors in long-term breast cancer survivors compared with non-cancer controls.
Cardiooncology

ProCardio Center for Innovation, Department of Cardiology, Oslo University Hospital, Oslo, Norway.
Background: Although anthracycline-related cardiotoxicity is widely studied, only a limited number of echocardiographic studies have assessed cardiac function in breast cancer survivors (BCSs) beyond ten years from anthracycline treatment, and the knowledge of long-term cardiorespiratory fitness (CRF) in this population is scarce. This study aimed to compare CRF assessed as peak oxygen uptake (V̇O), cardiac morphology and function, and cardiovascular (CV) risk factors between long-term BCSs treated with anthracyclines and controls with no history of cancer.
Methods: The CAUSE (Cardiovascular Survivors Exercise) trial included 140 BCSs recruited through the Cancer Registry of Norway, who were diagnosed with breast cancer stage II to III between 2008 and 2012 and had received treatment with epirubicin, and 69 similarly aged activity level-matched controls.
The expression of MALAT1, plasma brain natriuretic peptide, and Tei index in sepsis-induced myocardial injury.

Emergency and Critical Care Center, Renmin Hospital, Hubei University of Medicine, Shiyan, Hubei, China.
Purpose: We sought to investigate the expression of MALAT1, plasma brain natriuretic peptide, and Tei index in sepsis-induced myocardial injury.
Methods: The current retrospective analysis focused on 146 sepsis patients admitted to our hospital from February 2021 to March 2023. Based on the presence or absence of myocardial injury, the patients were divided into two groups: the sepsis group (n = 80) and the sepsis-induced myocardial injury group (n = 66).
Norepinephrine titration in patients with sepsis-induced encephalopathy: cerebral pulsatility index compared to mean arterial pressure guided protocol: randomized controlled trial.

Department of Anesthesia, Surgical Intensive Care and Pain Medicine, Faculty of Medicine, Tanta University Hospitals, Tanta, Gharbya, Egypt.
Background: Although surviving sepsis campaign (SSC) guidelines are the standard for sepsis and septic shock management, outcomes are still unfavourable. Given that perfusion pressure in sepsis is heterogeneous among patients and within the same patient; we evaluated the impact of individualized hemodynamic management via the transcranial Doppler (TCD) pulsatility index (PI) on mortality and outcomes among sepsis-induced encephalopathy (SIE) patients.
Methods: In this prospective, single-center randomized controlled study, 112 patients with SIE were randomly assigned.
Long-term efficacy of Mirabegron-anticholinergic combination in paediatric neurogenic bladder.

Department of Women and Children's Health, School of Life Course Sciences, Kings College London, London, UK; Children's Bladder Service, Evelina London Children's Hospital, Westminster Bridge Road, London, SE1 7EH, UK.
Introduction: The Mirabegron-anticholinergic (MAC) combination has proven effective as a step-up strategy in managing paediatric neurogenic bladder following anticholinergic medication and botulinum toxin (BTX) therapy. This study assesses the long-term efficacy of MAC in children with neurogenic bladder.
Patients And Methods: A retrospective chart review was conducted from 2015 to 2023, including consecutive paediatric patients receiving Mirabegron (25/50 mg) with an anticholinergic agent (solifenacin 16, tolterodine 7, oxybutynin 7, trospium 1).
Impact of sodium-glucose cotransporter 2 inhibitors on catheter ablation for atrial fibrillation in heart failure patients without type-2 diabetes.

Background: Sodium-glucose cotransporter 2 inhibitors (SGLT2is) reportedly decreased the new-onset atrial arrhythmias in patients with type-2 diabetes (T2DM) or heart failure (HF). This study examined the impact of SGLT2is on catheter ablation for atrial fibrillation (AF) in HF patients without T2DM.
Methods: Persistent AF (PeAF) and HF (N-terminal prohormone of brain natriuretic peptide, NT-proBNP ≥400 pg/ml) patients without T2DM undergoing catheter ablation were prospectively enrolled (n = 102).
