Purpose To quantify and compare the peak force applied on the glottis during endotracheal intubation across five laryngoscopy techniques, two intubation conditions (standard and simulated laryngospasm), and two operator experience levels, and to assess the effects of stylet use and operator anthropometric characteristics on applied force. Methods This prospective, manikin-based experimental study enrolled 50 operators (30 experienced, 20 less experienced). Each performed endotracheal intubation ...

Background: Cesarean section is one of the most commonly performed surgical procedures worldwide and is frequently associated with moderate to severe postoperative pain. While overall pain after cesarean delivery is well described, evidence comparing pain intensity and analgesic use between primary and repeat cesarean sections remains limited. Objective: To compare postoperative pain severity and total analgesic consumption within the first 24 hours among women undergoing primary versus repeat c...

BackgroundPropofol dosing guidelines recommend age-based reductions because hypnotic sensitivity increases in older adults. Most real-world evaluations of induction practice, however, have relied on total weight-normalized dose (mg/kg) rather than estimating cerebral exposure using pharmacokinetic models. Because age-related pharmacokinetic changes alter the relationship between administered dose and peak effect-site concentration (Ce,max), mg/kg surrogates may misrepresent true age-dependent ex...

ObjectiveTo compare the efficacy and safety of etomidate versus ketamine as induction agents for rapid sequence intubation in critically ill adults, focusing on 28-day mortality and post-intubation hypotension. Data SourcesPubMed, Embase, and the Cochrane Library were systematically searched from inception to January 2026. Reference lists of included studies were also manually screened. Study SelectionWe included randomized controlled trials (RCTs) comparing single-dose intravenous ketamine ve...

INTRODUCTIONRisks for postoperative cognitive dysfunction remain poorly understood. Traditional cognitive screening tools such as the Montreal Cognitive Assessment (MoCA) and the Mini-Mental State Examination (MMSE) are used for perioperative cognitive evaluation but have limited scope, whereas comprehensive in-person testing poses problems for long-term follow up. METHODSThis prospective cohort study assesses the feasibility of using a remotely performed comprehensive neurocognitive test batte...

Rapid prediction of the severity of acute coronary syndrome (ACS) is crucial for appropriate intervention in emergency department. Neutrophils (Neu), lymphocytes (Lym) and monocytes (Mon) and their ratios (Neu/Lym, NLR; Mon/Lym, MLR NeuxMon/Lym, SIRI) are acknowledged to be associated with the prediction of the severity and adverse outcome of ACS patients. Here, we analysed retrospectively eosinophils (Eos) and Eos-derived novel ratios (Neu/Eos, NER; Mon/Eos, MER; Neu x Mon/Eos, SIII; Neu/Eos x ...

BackgroundThere is disparity between the incidence of malignant hyperthermia (MH) reactions and the prevalence of variants in the RYR1 gene associated with susceptibility to MH (where susceptibility is determined by in vitro contracture tests). Our aims were to use clinical and genetic data from the UK to explain this disparity and to examine if these data are consistent with the clinical risk of MH being inherited as an autosomal dominant trait. MethodsClinical MH and genotyping data were extr...

BackgroundPostoperative delirium (POD) is a common complication of surgery. It is associated with a number of detrimental effects, including mortality and healthcare costs. We sought to determine whether common comorbidity indices are predictors of POD. MethodsUsing the Medical Information Mart for Intensive Care (MIMIC)-IV database, we identified 8022 abdominal surgery procedures across 7212 adult patients. We calculated both the Charlson comorbidity index (CCI) and the Elixhauser comorbidity ...

Background and AimsThe prognosis of interstitial lung diseases (ILDs) other than idiopathic pulmonary fibrosis (IPF) has not been studied as extensively as IPF. This study aimed to evaluate baseline factors associated with mortality in non-IPF ILD, including demographic characteristics, respiratory function test (RFT), comorbidities, and ILD subtypes. MethodsThis retrospective cohort study analysed prospectively collected data of patients with non-IPF ILD at a single tertiary centre in Malaysia...

BackgroundAlthough ST-segment elevation myocardial infarction (STEMI) and non-STEMI (NSTEMI) are very similar regarding pathophysiology and clinical treatments, especially NSTEMI comprises a much more heterogenic group of patients and underlying diseases. We therefore aimed to assess the treatments and outcomes of both entities in a large contemporary cohort. MethodsPatients with STEMI and NSTEMI between 01/2010 to 12/2018 were identified from the largest German Health Insurance (AOK, {approx}2...

BackgroundBronchiectasis is a debilitating respiratory condition characterized by chronic cough with expectoration of thick sputum. It accounts for significant morbidity and mortality, especially when associated with exacerbations. Assessing the health-related quality of life (HR-QoL) of patients with bronchiectasis is important to ascertain the impact of the disease on day-to-day life, as well as to gauge the effect of targeted interventions. Conventionally used methods for assessing HR-QoL suc...

Drug-induced liver injury (DILI) is an acute inflammatory liver disease caused not only by prescription and over-the-counter medications but also by health foods and dietary supplements. Typically, DILI patients recover once the causative substance is identified and discontinued. In contrast, autoimmune hepatitis (AIH) results from the immune-mediated destruction of hepatocytes due to a breakdown of self-tolerance mechanisms. Patients presenting with acute-onset AIH often lack characteristic cli...

AimsThis study aimed to examine the prevalence of malnutrition and its associations with functional capacity and quality of life (QoL) in AL and ATTR cardiac amyloidosis patients. Methods and ResultsThis cross-sectional pilot study included 29 patients with confirmed CA (14 AL, 15 ATTR). Data were collected between January 2020 and September 2021. Nutritional status was assessed using body mass index (BMI), anthropometric measures, and the Subjective Global Assessment (SGA). Functional capacity...

IntroductionRecent evidence has shown that vitamin C has analgesic properties in immediate postoperative context. However, while a clinical trial is currently underway to evaluate vitamin C for reducing opioid consumption in acute musculoskeletal (MSK) injuries emergency department (ED) patients, its direct analgesic effect in this population has not yet been established. This pilot study evaluated the feasibility of conducting a randomized placebo-controlled trial to determine the analgesic eff...

BackgroundArthroscopic rotator cuff repair (RCR) is a common surgical intervention used to address rotator cuff-related pain after other conservative interventions have been exhausted. With a continuing increase in procedures, evidence-based outcomes research is needed to identify key parameters of postoperative rehabilitation planning. ObjectiveWe aim to identify rehabilitation planning factors leading to better outcomes while also providing clinicians with reference data to describe the magni...

RationaleCardiopulmonary resuscitation (CPR) aims to provide oxygen to vital organs through chest compressions and ventilations, until return of spontaneous circulation (ROSC) is achieved. A major barrier to effective oxygenation during CPR is atelectasis, which impairs gas exchange and results in hypoxemia--a condition strongly associated with decreased rates of ROSC and worsened neurological outcomes. Positive end-expiratory pressure (PEEP) is routinely used in critical care to prevent atelec...

BackgroundPostoperative delirium is a common complication in surgical patients, and is associated with a multitude of negative outcomes, including mortality, dementia, and increased healthcare costs. Therefore, a better understanding of what factors contribute to postoperative delirium, especially those that can be easily obtained, is important. MethodsWe conducted a retrospective cohort study using patients from the Medical Information Mart for Intensive Care (MIMIC)-IV database. Adult patient...

BackgroundArthroscopic release for elbow stiffness is considered a minimally invasive and effective treatment. However, the extent to which each intraoperative step contributes to improvement in range of motion (ROM) has not been well investigated. PurposeTo sequentially evaluate the relationship between intraoperative surgical steps and changes in elbow ROM during arthroscopic release for severe elbow stiffness, and to identify the key procedural stage contributing most significantly to ROM im...
