Mitochondrial uncouplers inhibit oncogenic E2F1 activity and prostate cancer growth.

Mitochondrial uncouplers dissipate proton gradients and deplete ATP production from oxidative phosphorylation (OXPHOS). While the growth of prostate cancer depends on OXPHOS-generated ATP, the oncogenic pathway mediated by the transcription factor E2F1 is crucial for the progression of this deadly disease. Here, we report that mitochondrial uncouplers, including tizoxanide (TIZ), the active metabolite of the Food and Drug Administration (FDA)-approved anthelmintic nitazoxanide (NTZ), inhibit E2F1-mediated expression of genes involved in cell cycle progression, DNA synthesis, and lipid synthesis.

Placental alkaline phosphatase (PLAP): Is it exclusively placental?

Background: Adverse pregnancies outcomes present a clinical dilemma in Perinatal medicine. This is partly due to lack of accuracy of current biomarkers to predict high-risk pregnancies at an earlier stage. The placental alkaline phosphatase (PLAP) carrying extracellular vesicles (EVs), and their cargo have been reported as a source of biomarkers for placental health and an indication of pre-eclampsia progression.

Country economic status is strongly associated with burn survival - validation of the (modified) ABSI.

Background: Predicting burn-related mortality is vital for family counseling, triage, and resource allocation. Several of the burn-specific mortality prediction scores have been developed, including the Abbreviated Burn Severity Index (ABSI) in 1982. However, these scores are not tested for accuracy to support contemporary estimates of the global burden of burn injury.

Impact of kidney disease in patients undergoing catheter directed interventions for intermediate to high-risk pulmonary embolism.

Background: Catheter-directed interventions (CDIs) for pulmonary embolism (PE) continue to evolve. However, due to the paucity of data, their use has been limited in patients with underlying kidney disease.

Methods: The National Readmission Database (2016-2020) was utilized to identify intermediate to high-risk PE (IHR-PE) patients requiring CDI (thrombectomy, thrombolysis, and ultrasound-assisted thrombolysis).

Global Epidemiology of Alcohol-Related Liver Disease, Liver Cancer, and Alcohol Use Disorder, 2000-2021.

Background/aims: Alcohol represents a leading burden of disease worldwide, including alcohol use disorder (AUD) and alcohol-related liver disease (ALD). We aim to assess the global burden of AUD, ALD, and alcohol-attributable primary liver cancer between 2000-2021.

Methods: We registered the global and regional trends of AUD, ALD, and alcohol-related liver cancer using data from the Global Burden of Disease 2021 Study, the largest and most up-to-date global epidemiology database.

Ferumoxytol-enhanced MRI of retroplacental clear space disruption in placenta accreta spectrum.

Introduction: Placenta accreta spectrum (PAS) occurs when the placenta is pathologically adherent to the myometrium. An intact retroplacental clear space (RPCS) is a marker of normal placentation. In this study, we investigate use of the FDA-approved iron supplement ferumoxytol for contrast-enhanced MRI of the RPCS in mouse models of normal pregnancy and PAS.

Application of Reverse Sural Flaps in Pediatric Patients: A Systematic Review.

Introduction: The reverse sural flap (RSF) is a random-type, pedicled flap based on sural artery perforators indicated for traumatic lower-extremity wounds. The RSF has demonstrated comparable results to free flap placement in the adult population for reconstruction of distal third defects, but few reports describe its application and outcomes in the pediatric population.

Methods: We investigated RSF application in pediatric patients (<18 years of age) through systematic review and meta-analysis.

Patient Characteristics and Outcomes by Sex and Smoking Status in Pulmonary and Cardiac Rehabilitation.

Introduction: Those with established symptomatic cardiopulmonary disease should attend secondary prevention programs. Attendance at these programs is known to differ by sex and by smoking status, with females and those who smoke being less likely to attend. However, little is known about whether the risk factors of being female and smoking are cumulative, and how outcomes from secondary prevention differ by these subgroups.

Outcomes of catheter ablation in cardiac sarcoidosis patients with ventricular tachycardia: a propensity score-matched retrospective analysis.

Background: Ventricular tachycardia (VT) in patients with cardiac sarcoidosis (CS) can lead to sudden cardiac death. The role of ventricular tachycardia ablation (VTA) in CS has been investigated in a few small, single-center, and larger observational studies, but the evidence still needs to be provided. This study aimed to investigate the clinical outcomes of VTA in patients with CS admitted with a diagnosis of VT.

Expert Rater Agreement for Symptoms and Diagnosis of Bipolar Disorder in Youth.

The diagnosis of bipolar disorder (BD) in young children has been a topic of debate, in part owing to varied interpretation of manic-like symptoms. We examined how expert academic clinicians participating in the pediatric bipolar biobank varied in their interpretation and application of Diagnostic and Statistical Manual of Mental Disorders (DSM) criteria and diagnoses. Study co-investigators reviewed 12 standardized narratives and for each marked a visual analog scale with their confidence in the presence of manic episodes and criteria.

E-cigarettes increase the risk of adenoma formation in murine colorectal cancer model.

E-cigarettes (E.cigs) cause inflammation and damage to human organs, including the lungs and heart. In the gut, E.

Role and Prognostic Implications of Venous Outflow Assessment in Acute Ischemic Stroke.

Introduction: The venous outflow profile (VOP) is a crucial yet often overlooked aspect affecting stroke outcomes. It plays a major role in the physiopathology of acute cerebral ischemia, as it accounts for both the upstream arterial collaterals and cerebral microperfusion. This enables it to circumvent the limitations of various arterial collateral evaluation systems, which often fail to consider impaired autoregulation and its impact on cerebral blood flow at the microcirculatory levels.

Safety and efficacy of three alternative regimens against relapsing Plasmodium vivax malaria in glucose 6-phosphate dehydrogenase deficient patients in the Brazilian Amazon (ALTPRIM).

Background: Daily primaquine-induced hemolysis is a common cause of complications during Plasmodium vivax malaria treatment in individuals with glucose 6-phosphate dehydrogenase deficiency (G6PDd). Alternative regimens balancing safety and efficacy are needed.

Methods: G6PDd participants with P.

Cohort and Gender Differences in Stability Over Five Years Among Mexican-Origin Caregivers to Older Adults Living With Cognitive Impairment.

The current study examines cohort (i.e., Generation X, Baby Boomers, and Silent Generation) and gender differences in the stability of Mexican-origin family caregivers over time.

Gene signatures derived from transcriptomic-causal networks stratify colorectal cancer patients for effective targeted therapy.

Background: Gene signatures derived from transcriptomic-causal networks offer potential for tailoring clinical care in cancer treatment by identifying predictive and prognostic biomarkers. This study aimed to uncover such signatures in metastatic colorectal cancer (CRC) patients to aid treatment decisions.

Methods: We constructed transcriptomic-causal networks and integrated gene interconnectivity into overall survival (OS) analysis to control for confounding genes.

Developing an Annual Review of the Literature.

Many national meetings and speaker series feature an "Annual Review of the Literature" (ARL) session in which an individual or team presents a sampling of articles, selected and prepared because they represent important current topics or new ideas in the discipline of interest. Despite this, there is little in the medical literature describing how to thoughtfully and systematically develop these sessions. We identify best practices that we have developed and used in the United States Clerkship Directors of Internal Medicine (CDIM) over many years.

Local flap guidance for scalp reconstruction following Mohs micrographic surgery.

Keratinocyte carcinomas (KCs) are commonly located on the scalp and often treated with excision with peripheral and deep en face margin assessment (PDEMA), with Mohs micrographic surgery (MMS) being the most frequently used method. Resection of these malignancies results in wounds with a wide variety of sizes, ranging from small, sub-centimeter defects, to extensive, nearly complete scalp defects. MMS is often the preferred treatment for tumor resection and margin clearance, as it allows for maximal healthy tissue preservation and has the lowest recurrence rates.

Oral cavity and oropharyngeal cancers in Texas: examining incidence rates in dental health professional shortage areas.

Purpose: Oral cavity (OC) and oropharyngeal (OP) cancer rates have increased annually rising in the U.S. and Texas.

Nanoscopy reveals integrin clustering reliant on kindlin-3 but not talin-1.

Background: Neutrophils are the most abundant leukocytes in human blood, and their recruitment is essential for innate immunity and inflammatory responses. The initial and critical step of neutrophil recruitment is their adhesion to vascular endothelium, which depends on G protein-coupled receptor (GPCR) triggered integrin inside-out signaling that induces β2 integrin activation and clustering on neutrophils. Kindlin-3 and talin-1 are essential regulators for the inside-out signaling induced β2 integrin activation.

Methods: The RPA-LF assays were tested at different temperatures and reaction times, using DNA from cultured L. braziliensis and L.

Single-nucleus RNA sequencing reveals distinct pathophysiological trophoblast signatures in spontaneous preterm birth subtypes.

Spontaneous preterm birth (sPTB) poses significant challenges, affecting neonatal health and neurodevelopmental outcomes worldwide. The specific effects of placental trophoblasts on the pathological development of sPTB subtypes-preterm premature rupture of fetal membranes (pPROM) and spontaneous preterm labor (sPTL)-are not fully understood, making it crucial to uncover these impacts for the development of effective therapeutic strategies. Using single-nucleus RNA sequencing, we investigated transcriptomic and cellular differences at the maternal-fetal interface in pPROM and sPTL placentas.
