α-Catenin force-sensitive binding and sequestration of LZTS2 leads to cytokinesis failure.

Epithelial cells can become polyploid upon tissue injury, but mechanosensitive cues that trigger this state are poorly understood. Using an Madin Darby Canine Kidney (MDCK) cell knock-out/reconstitution system, we show that α-catenin mutants that alter force-sensitive binding to F-actin or middle (M)-domain promote cytokinesis failure and binucleation, particularly near epithelial wound-fronts. We identified Leucine Zipper Tumor Suppressor 2 (LZTS2), a factor previously implicated in abscission, as a conformation sensitive proximity partner of α-catenin.

The association between maternal depression and anxiety symptoms during pregnancy and child sleep patterns at age 3 years.

Background: Childhood sleep problems are common and impact physical and emotional health. Prior work suggests that prenatal maternal depression and anxiety associate with disturbed child sleep in infancy. The current study evaluated whether these same associations extend to children at 3 years of age, and if so, whether the timing of symptoms in pregnancy is relevant.

Association Between Early Immunosuppression Center Variability and One-Year Outcomes After Pediatric Liver Transplant.

Background: Despite the existence of institutional protocols, liver transplant centers often have variability in early immunosuppression practices. We aimed to measure within-center variability in early immunosuppression after pediatric liver transplant (LT) and examine its association with one-year outcomes.

Methods: We analyzed pediatric LTs from 2013 to 2018 in the United Network for Organ Sharing registry, with data aggregated by center.

Endoscopic techniques for the diagnosis of pancreatic cystic lesions.

Pancreatic cysts are mostly incidental findings on computed tomography or magnetic resonance imaging scans, with few patients presenting with abdominal pain or other symptoms. The accurate diagnosis of cysts is important as management depends on the type (neoplastic or non-neoplastic). Cross-sectional imaging is fast being replaced with endoscopic ultrasound (EUS) and various techniques based on that such as EUS-guided fine needle aspiration, EUS-guided needle confocal laser endomicroscopy, EUS-through-the-needle biopsy, and contrast-enhanced EUS.

Chronic viral mimicry induction following p53 loss promotes immune evasion.

Epigenetic therapies facilitate transcription of immunogenic repetitive elements that cull cancer cells through 'viral mimicry' responses. Paradoxically, cancer-initiating events also facilitate transcription of repetitive elements. Contributions of repetitive element transcription towards cancer initiation, and the mechanisms by which cancer cells evade lethal viral mimicry responses during tumor initiation remain poorly understood.

Maintenance therapy with a P2Y12 receptor inhibitor after cangrelor in patients with acute coronary syndrome. The ELECTRA-SIRIO 2 investigators' viewpoint.

According to the ESC guidelines, cangrelor may be considered in P2Y12-inhibitor-naïve acute coronary syndrome (ACS) patients undergoing percutaneous coronary intervention (PCI). The aim of this review is to summarize available evidence on the optimal maintenance therapy with P2Y12 receptor inhibitor after cangrelor. Transitioning from cangrelor to a thienopyridine, but not ticagrelor, can be associated with a drug-drug interaction (DDI); therefore, a ticagrelor loading dose (LD) can be given any time before, during, or at the end of a cangrelor infusion, while a LD of clopidogrel or prasugrel should be administered at the time the infusion of cangrelor ends or within 30 minutes before the end of infusion in the case of a LD of prasugrel.

Comparative outcomes of Palmer, Umbilical Veress needle, and open entry techniques in robotic-assisted surgery: a propensity-matched analysis of 9482 patients.

Robotic-assisted surgery offers several advantages over traditional methods, such as reduced blood loss and fewer complications. Establishing pneumoperitoneum is a critical step, with two primary techniques: the Veress needle (closed) and the Hasson (open) technique. Despite extensive studies in laparoscopic surgery, limited data exist regarding their use in robotic surgery.

Catheter Ablation in Atrial Fibrillation: Recent Advances.

Atrial fibrillation (AF) is the leading cause of arrhythmia-related morbidity and mortality. Recurrent symptoms, hospitalizations, and cost burden to patients have necessitated treatments beyond antiarrhythmic drugs (AADs) for patients with AF. Catheter ablation has proven to be effective over medical therapy alone; however the recurrence rates for atrial tachyarrhythmias post-ablation remain significant, particularly in patients with persistent and long-standing persistent AF.

Patterns of Brain Injury and Clinical Outcomes Related to Trauma from Collisions Involving Motor Vehicles.

: Despite improvements in technology and safety measures, injuries from collisions involving motor vehicles (CIMVs) continue to be prevalent. Therefore, our goal is to investigate the different patterns of head injuries associated with CIMVs. : This is a single-center, retrospective study of patients with motor vehicle-related trauma between 1 January 2016-31 December 2023.

Effect of Skin-to-Skin Care on the Day of Birth on Skin Colonization in Preterm Infants: A Pre- and Post-Implementation Study.

Background/objectives: Maternal skin-to-skin contact (MSSC) in neonates has been shown to reduce nosocomial infections. In preterm infants, exposure to maternal skin commensals within the first 24 h may prevent colonization by hospital-acquired pathogens. However, the impact of early MSSC on skin colonization in preterm infants is unknown.

Lactate Is a Strong Predictor of Poor Outcomes in Patients with Severe Traumatic Brain Injury.

Lactate is a byproduct of glycolysis, often linked to oxygen deprivation. This study aimed to examine how lactate levels (LLs) affect clinical outcomes in patients with severe TBI, hypothesizing that higher LLs would correlate with worse outcomes. : This is a level 1 single-center, retrospective study of patients with severe TBI between 1 January 2020 and 31 December 2023, inclusive.

The Phenotype Changes of Astrocyte During Different Ischemia Conditions.

Objectives: Dementia is becoming a major health problem in the world, and chronic brain ischemia is an established important risk factor in predisposing this disease. Astrocytes, as one major part of the blood-brain barrier (BBB), are activated during chronic cerebral blood flow hypoperfusion. Reactive astrocytes have been classified into phenotype pro-inflammatory type A1 or neuroprotective type A2.

Birth weight and head circumference for 22-29 weeks gestation neonates from an international cohort.

Objective: Size at birth is a key indicator of in utero growth. Our objective was to generate sex-specific percentiles for birth weight and head circumference in neonates born between 22 and 29 weeks gestation from pregnancies without hypertension or diabetes and assess differences between vaginal and caesarean births and between singletons and twins.

Methods: We used data from 12 countries participating in the International Network for Evaluating Outcomes in Neonates database from 2007 to 2021.

Oxytocin versus carbetocin at elective Cesarean delivery in parturients with class III obesity: a double-blind randomized controlled noninferiority trial.

Purpose: Class III obesity (body mass index [BMI] ≥ 40 kg·m) is associated with high rates of Cesarean deliveries and postpartum hemorrhage, with increased maternal and fetal morbidity. The doses of oxytocin and carbetocin are two to four times higher at Cesarean delivery in patients with class III obesity. We sought to investigate the efficacy of carbetocin 80 µg iv compared with oxytocin 1 IU iv (plus infusion) at elective Cesarean delivery in parturients with class III obesity.

The patient was diagnosed with a right-sided hemorrhagic synovial cyst at the C7-T1 level.

The doctor will polygraph you now.

Artificial intelligence (AI) methods have been proposed for the prediction of social behaviors that could be reasonably understood from patient-reported information. This raises novel ethical concerns about respect, privacy, and control over patient data. Ethical concerns surrounding clinical AI systems for social behavior verification can be divided into two main categories: (1) the potential for inaccuracies/biases within such systems, and (2) the impact on trust in patient-provider relationships with the introduction of automated AI systems for "fact-checking", particularly in cases where the data/models may contradict the patient.

Objective: To evaluate the worldwide use of FIGO's two systems for the classification of causes and contributors to nongestational abnormal uterine bleeding in the reproductive years by obstetrics and gynecology professionals worldwide, to identify knowledge gaps, and explore barriers to implementation.

Methods: An electronic survey was developed by members of FIGO's Menstrual Disorders and Related Health Impacts (MDRHI) Committee to assess knowledge of abnormal uterine bleeding (AUB) and the two FIGO AUB systems among obstetricians and gynecologists. The survey was conducted online from February 28 to June 30, 2023, and comprised demographic questions, educational content inquiries, and a knowledge assessment.

Patellar Instability after Total Knee Arthroplasty.

Patellar instability following total knee arthroplasty (TKA) is a rare, yet serious complication, potentially requiring revision surgery or resulting in chronic dysfunction. When encountered, it is paramount to understand the etiologies, diagnostic approaches, treatment options, and outcomes of the selected treatment. The most common cause of patella instability is improper positioning of components, leading to lateral maltracking of the patella.
