Lateralization in reverse shoulder arthroplasty (RSA) refers to moving the reconstructed center of rotation, humeral articulation, or both laterally relative to the markedly medialized Grammont-style design. It may be produced on the glenoid side, the humeral side, or through combined bipolar modification. Lateralization is intended to reduce scapular notching and impingement, improve external rotation and residual rotator-cuff mechanics, restore soft-tissue tension, and enhance stability. Comparative evidence generally supports reduced notching and improved external rotation with lateralized constructs, although improvements in elevation, internal rotation, patient-reported outcomes, and stability are less consistent. The principal disadvantages include increased deltoid and joint-reaction forces, greater glenoid baseplate loading, possible over-tensioning, and increased acromial or scapular-spine stress. Because implant geometry, component position, scapular anatomy, and soft-tissue status substantially influence outcomes, no universal amount or location of lateralization has been established.

Read the full reviewDifferences between potassium measured on a blood-gas analyzer and potassium measured in serum in patients with chronic kidney disease (CKD) may reflect preanalytical factors, specimen-matrix differences, analytical variation, or genuine biological changes. Blood-gas analysis generally uses rapidly analyzed, heparinized whole blood, whereas serum potassium is measured after clotting, transport, centrifugation, and analysis on a chemistry platform. Hemolysis, delayed processing, temperature, transport, clotting-related potassium release, thrombocytosis, leukocytosis, sampling location, and analyzer methodology may therefore produce discordant results. CKD-related impairment of potassium excretion and associated acid–base or treatment changes can also cause genuine temporal variation. The supplied evidence does not directly establish a CKD-specific bias, conversion factor, or quantitative comparison between blood-gas and serum potassium. Unexpected discrepancies should consequently be evaluated with attention to specimen quality, blood counts, timing, sampling conditions, acid–base status, dialysis, and medications.
Question: Causes of differences between blood gas potassium and serum potassium in chronic kidney disease patients
Read the full reviewEvidence directly evaluating agreement between point-of-care (POC) or blood-gas potassium and central laboratory serum or plasma potassium in chronic kidney disease (CKD) is limited, heterogeneous, and concentrated in patients receiving hemodialysis. Available studies generally indicate good concordance and low systematic bias, supporting POC testing as a rapid assessment when urgent decisions are required. However, important exceptions include clinically meaningful individual differences, incomplete reporting of method-comparison statistics, uncertainty regarding specimen types and analyzers, and limited evaluation across CKD stages and marked hyperkalemia. POC results that are unexpected, markedly abnormal, or treatment-critical should therefore be confirmed by central laboratory measurement, with interpretation accounting for hemolysis, collection technique, specimen matrix, and processing delays.

Read the full reviewBroiler ascites, also termed pulmonary hypertension syndrome (PHS), is a multifactorial cardiopulmonary and metabolic disorder arising when oxygen demand exceeds the functional capacity of the cardiopulmonary system. Rapid growth, high metabolic rate, limited pulmonary vascular capacity, environmental stress, vascular remodeling, and genetic susceptibility can increase pulmonary vascular resistance and pulmonary arterial pressure. The resulting right-ventricular hypertrophy and failure produce venous congestion and fluid accumulation in the abdominal cavity. Evidence indicates that modern production traits, cold exposure, hypoxia, inadequate ventilation, high stocking density, ammonia, and other conditions contribute to disease expression. Prevention combines controlled growth, appropriate nutrition and temperature management, effective ventilation, and genetic selection for resistance.

Read the full reviewLow bone mineral density (BMD) is common after spinal cord injury (SCI), but the prevalence of BMD below the expected range for age in younger adults remains uncertain. In a retrospective study of 63 adults aged 18–50 years, 38.1% had a DXA Z-score of ≤ −2.0. Other studies used T-scores, absolute BMD thresholds, or comparisons with age-matched controls, limiting direct synthesis. Bone loss is predominantly regional, with the femoral neck, total hip, distal femur, and proximal tibia more affected than the lumbar spine. Associated factors include longer time since injury, early immobilization, complete or severe neurological injury, lower body mass index, reduced muscle mass, poorer fitness, limited mechanical loading, smoking, and increased bone turnover. Fracture risk is not fully captured by DXA-defined BMD and may also reflect mobility, falls, spasticity, muscle mass, and bone quality. Larger prospective studies using standardized age-adjusted Z-scores and consistent hip and knee measurement sites are needed.

Read the full reviewAutonomous AI agents can plan and execute multistep tasks, access data and external tools, modify software or models, coordinate with other agents, and act in high-impact environments. These capabilities require governance that is risk-proportionate, capability-based, lifecycle-oriented, and sensitive to context. The supplied evidence supports a layered framework combining agentic profiling, bounded authority, least-privilege access, sandboxing, meaningful human oversight, transparency, validation, continuous monitoring, incident response, privacy and security controls, and clearly assigned accountability. Governance should address not only initial deployment but also tool use, memory, adaptation, self-correction, self-improvement, model and code modification, and changing operating contexts. Because autonomy can produce cascading errors, unauthorized actions, unclear responsibility, and behavior that changes after deployment, increasing autonomy should be matched by stronger authorization, traceability, verification, supervision, and rollback or shutdown capacity. In high-stakes settings, autonomous systems should augment rather than replace qualified human judgment.

Read the full reviewBroiler ascites, also called pulmonary hypertension syndrome, pulmonary arterial hypertension syndrome, or right-sided heart failure, is a multifactorial disorder characterized by pulmonary hypertension, right-ventricular remodeling, venous congestion, and accumulation of protein-containing fluid in the abdominal cavity. Its development reflects an imbalance between the high oxygen requirements of rapidly growing broilers and the capacity of their pulmonary and cardiovascular systems to deliver oxygen. Limited pulmonary vascular capacity, hypoxic pulmonary vasoconstriction, vascular remodeling, altered blood rheology, respiratory impairment, myocardial injury, environmental stress, and genetic susceptibility all contribute to disease expression. Hypoxia, cold exposure, inadequate ventilation, high altitude, and nutritional strategies that promote excessive growth can increase risk. Genetic variation is substantial, supporting selection for resistance, while management approaches that moderate growth and maintain oxygen availability can reduce incidence, although potential effects on production performance must be considered.

Read the full reviewMedical–legal risk in gastroenterology is expanding beyond diagnostic error, procedural complications, informed consent, documentation, supervision, and follow-up to include artificial intelligence (AI), privacy, cybersecurity, algorithmic bias, vendor accountability, and institutional governance. AI is increasingly used in colonoscopy, pathology and imaging support, clinical documentation, triage, patient communication, research, and quality improvement. However, current evidence remains limited by insufficient real-world validation, incomplete assessment of fairness and calibration, uncertain long-term outcomes, and variable clinical generalizability (PMID: 39405325). AI should therefore generally function as clinician-supervised decision support rather than autonomous diagnosis or treatment. A defensible framework for UC Irvine requires approved tools, local validation, meaningful human oversight, transparent documentation, closed-loop follow-up, privacy protection, equity monitoring, explicit trainee supervision, and continuous reassessment. The supplied evidence does not verify any specific bill signed or vetoed by Governor Newsom on September 30, 2026, or any change in California or UC Irvine awards; those claims require confirmation through official sources.

Read the full reviewImpella is a catheter-based microaxial-flow device that provides temporary mechanical circulatory support by moving blood from the left ventricle into the ascending aorta. Direct ventricular unloading can reduce left-ventricular workload, wall stress, and myocardial oxygen demand while increasing mean arterial pressure and systemic perfusion. Its principal applications include cardiogenic shock, high-risk percutaneous coronary intervention, selected cases of venoarterial extracorporeal membrane oxygenation, ventricular tachycardia ablation, and increasingly high-risk cardiac surgery. The Impella 2.5 and Impella CP have been used extensively in acute coronary syndrome-associated cardiogenic shock, whereas the Impella 5.5 has broadened options for prolonged support and bridging to recovery, transplantation, or durable ventricular assist devices. Observational studies demonstrate meaningful hemodynamic support and potential bridging benefits, but mortality remains substantial and complications—including bleeding, vascular injury, limb ischemia, hemolysis, thrombocytopenia, and valvular or aortic injury—are important. Randomized evidence has demonstrated a survival benefit with Impella CP in selected patients with ST-elevation myocardial infarction and cardiogenic shock, although at the cost of increased major bleeding, hemolysis, and vascular complications. Current evidence therefore supports individualized use, careful timing, intensive monitoring, and continued evaluation of patient selection, support duration, and complication prevention.

Read the full reviewLa prevención y el control de la fiebre amarilla selvática requieren un enfoque integrado de salud humana, animal y ambiental. La vacunación sostenida y de alta cobertura constituye la intervención principal, mientras que la vigilancia de casos humanos, primates no humanos, mosquitos vectores y condiciones ecológicas permite detectar tempranamente la circulación viral. La confirmación diagnóstica, la búsqueda activa de casos, la investigación de epizootias, el análisis espacial y temporal, la comunicación comunitaria y la respuesta rápida son componentes esenciales. La evidencia disponible también resalta la necesidad de diferenciar los ciclos selvático y urbano, reducir los retrasos operativos y priorizar territorios y poblaciones susceptibles según indicadores epidemiológicos, entomológicos y ambientales.
