Sexual Harassment in Academic Anesthesiology: A Survey of Prevalence, Sources, Impact, and Recommendations.

Background: A report by the American Association of Medical Colleges (AAMC) showed that academic anesthesiology has the highest prevalence of sexual harassment among specialties for both men and women. We aimed to explore the prevalence, sources, and impact of sexual harassment on anesthesiologists in academic centers in the United States and Canada. We also sought recommendations for its mitigation.

Incorporating Economic Evidence in Clinical Guidelines: A Framework From the Clinical Guidelines Committee of the American College of Physicians.

In recognition of accelerating health care spending and alignment with the American College of Physicians (ACP) principles of promoting high-value care, the ACP Clinical Guidelines Committee (CGC) developed a framework to standardize its approach to identifying, appraising, and considering economic evidence in the development of ACP clinical guidelines. This article presents the CGC's process for incorporating economic evidence, which encompasses cost-effectiveness analyses, economic outcomes in randomized controlled trials, and resource utilization (intervention cost) data. Economic evidence is one component of ACP recommendations.

Development of a physical performance summary score in middle age: Findings from the CARDIA Function study.

Few physical performance batteries exist that appropriately evaluate physical limitations in middle-aged adults. We aimed to develop a physical performance summary score that is appropriate for use in epidemiology studies of middle-aged adults using data from the Coronary Artery Risk Development in Young Adults (CARDIA) Function study, which assessed self-reported function (PROMIS-SF20a) and physical performance measures (gait speed, balance, lower-body strength, grip strength, and cardiovascular endurance). The CARDIA Physical Performance (CAPP) score was developed using sex-specific quartiles, assigning points based on these quartiles (0 for not attempted, 1-4 for each quartile), and summing points across all performance measures (0-20, higher scores reflect greater performance).

Updating probability of pathogenicity for RYR1 and CACNA1S exon variants in individuals without malignant hyperthermia after exposure to triggering anesthetics.

Objectives: We aimed to classify genetic variants in RYR1 and CACNA1S associated with malignant hyperthermia using biobank genotyping data in patients exposed to triggering anesthetics without malignant hyperthermia phenotype.

Methods: We identified individuals who underwent surgery and were exposed to triggering anesthetics without malignant hyperthermia phenotype and who had RYR1 or CACNA1S genotyping data available in our biobank. We classified all variants in the cohort using a Bayesian framework of the American College of Medical Genetics and Genomics and the Association of Molecular Pathologists guidelines for variant classification and updated the posterior probabilities from this model with the new information from our biobank cohort.

A Borenium-Borane Composite for Exhaustive Reduction of Oxo-Chemicals.

Borenium ions have attracted significant attention in organic transformations due to their strong Lewis acidity. The reported borenium ions are often stabilized by sterically demanding substituents and strong coordination bonds. Herein, we have synthesized a small steric borenium-equivalent NHBHOTf and subjected it to the exhaustive reduction of a carboxylic functional group to a methyl group, which shows broad functional group tolerance.

Assessing chest radiographic quality and the influence of COVID-19 pathology: the Australian experience.

Introduction: Quality assurance (QA) in medical imaging ensures consistently high-quality images at acceptable radiation doses. However, the applicability of the chest X-ray (CXR) QA tool in images with pathology, particularly infectious diseases like COVID-19, has not been explored. This study examines the utility of the European Guidelines for image quality in QA of CXRs with varying severity and types of infectious disease.

Metabolomics survey of uropathogenic bacteria in human urine.

Introduction: Urinary tract infections (UTIs) are one of the most prevalent infections in North America and are caused by a diverse range of bacterial species. Although uropathogenesis has been studied extensively in the context of macromolecular interactions, the degree to which metabolism may contribute to infection is unclear. Currently, most of what is known about the metabolic capacity of uropathogens has been derived from genomics, genetic knockout studies or transcriptomic analyses.

On the gold(I)-catalyzed enantioselective addition of indole to diphenylallene via anion-binding catalysis.

Neutral dual hydrogen bond donors (HBDs) are effective catalysts that enhance the electrophilicity of substrates or the Lewis/Brønsted acidity of reagents through an anion-binding mechanism. Despite their success in various enantioselective organocatalytic reactions, their application to transition metal catalysis remains rare. Herein, we report the activation of gold(I) precatalysts by chiral ureas, leading to enantioselective hydroarylation of allenes with indoles.

Establishing the African region monitoring vaccine effectiveness (AFRO-MoVE) network for respiratory pathogens.

Population-level vaccination with newly developed vaccines to respond to the COVID-19 pandemic created a need to monitor vaccine effectiveness (VE) in the context of emerging SARS-CoV-2 variants and changing epidemiology. WHO and partners launched the African Region Monitoring Vaccine Effectiveness (AFRO-MoVE) Network in March 2021 to assess the performance of COVID-19 vaccines in real-world conditions in Africa. The Network aimed to facilitate and support comparable COVID-19 vaccine effectiveness studies in the African region, to provide a platform of scientific expertise and infrastructure, encourage the use of robust similar study designs to enable pooling to produce regional VE estimates and to build a sustainable network of hospitals, institutions, and experts to evaluate vaccines against pandemic and endemic respiratory pathogens.

Transamniotic Delivery of Hematopoietic Stem Cells Genetically Modified to Carry a Human Hemoglobin Subunit Beta Gene (HBB) in a Healthy Rodent Model.

Background: We sought to determine whether transamniotic stem cell therapy (TRASCET) could be a viable alternative for the fetal administration of genetically modified hematopoietic stem cells (HSCs) carrying a human hemoglobin subunit beta gene (hHBB) in a healthy syngeneic rat model.

Methods: Time-dated pregnant Lewis dams underwent volume-matched intra-amniotic injections in all their fetuses (n = 61) of a suspension of donor HSCs genetically modified with either both a hHBB gene and a firefly luciferase reporter gene (n = 42) or the firefly luciferase reporter gene alone to control for HBB-derived protein interspecies homology (n = 19) on gestational day 17 (E17; term = E21). Donor HSCs consisted of syngeneic cells phenotyped by flow cytometry with successful hHBB transduction confirmed by ELISA prior to administration in vivo.

A fucose-binding superlectin from Enterobacter cloacae with high Lewis and ABO blood group antigen specificity.

Bacteria frequently employ carbohydrate-binding proteins, so-called lectins, to colonize and persist in a host. Thus, bacterial lectins are attractive targets for the development of new antiinfectives. To find new potential targets for antiinfectives against pathogenic bacteria, we searched for homologs of Pseudomonas aeruginosa lectins and identified homologs of LecA in Enterobacter species.

A physico-chemical rationale for the varied catalytic efficiency in RNase J paralogues.

Paralogues of the bifunctional nuclease, Ribonuclease J (RNase J) demonstrate varied catalytic efficiencies despite extensive sequence and structural similarity. Of the two S. aureus RNase J paralogues, RNase J1 is substantially more active than RNase J2.

Transcription factor clusters as information transfer agents.

Deciphering how genes interpret information from transcription factor (TF) concentrations within the cell nucleus remains a fundamental question in gene regulation. Recent advancements have revealed the heterogeneous distribution of TF molecules, posing challenges to precisely decoding concentration signals. Using high-resolution single-cell imaging of the fluorescently tagged TF Bicoid in living embryos, we show that Bicoid accumulation in submicrometer clusters preserves the spatial information of the maternal Bicoid gradient.

Atorvastatin-Induced Liver Injury With Concurrent Rhabdomyolysis After a Positive Rechallenge.

Statin-induced liver injury has been widely described. However, cases of clinically significant liver injury are rare. We present a 56-year-old woman who developed atorvastatin-induced grade III acute liver injury with concurrent rhabdomyolysis that worsened after rechallenging, which highlighted the need for pharmacovigilance with statins.

Facile and Highly Selective Deprotection of Aryl Propionates/Acetates Using a Supported Lewis Acid Catalyst (20% InCl/MCM-41).

The selective deprotection of substituted aryl esters like acetates and propionates in the presence of different electron-donating and -withdrawing functional groups to the corresponding phenols in good yields was reported using the Lewis acid supported solid acid catalyst 20 InCl/MCM-41 prepared by the wet impregnation method. The textural and microscopic properties of the catalyst were studied, which revealed a high degree of dispersion of InCl over MCM-41, promising quantification of Lewis acidity, and well-ordered honeycomb structure. The methodology was further explored for the selective deprotection of acetates and propionates in the presence of substituted amides that remain unaltered.

State Medicaid Policies Governing Access to Medications for Opioid Use Disorder (MOUD) and MOUD Treatment Use in a Large Sample of People Who Inject Drugs in 20 U.S. States.

Background: People who inject drugs (PWID) are especially vulnerable to harms from opioid use disorder (OUD). Medications for OUD (MOUD) effectively reduce overdose and infectious disease transmission risks.

Objective: We investigate whether state Medicaid coverage for methadone and buprenorphine is related to past-year MOUD use among PWID using cross-sectional, multilevel analyses with individual-level data on PWID from the Centers for Disease Control and Prevention's 2018 National HIV Behavioral Surveillance.

Kisspeptin Retards Tumor Growth of Lewis Lung Carcinoma Cells Through p38 MAPK-mediated Senescence.

Background/aim: Kisspeptin has multifaceted roles in both normal and pathological conditions. Although lung cancer is a leading cause of cancer worldwide, the role of kisspeptin in lung cancer remains poorly understood. Thus, this study aimed to investigate the effects of kisspeptin on lung cancer.

Current concepts of fourth-generation minimally invasive and open hallux valgus surgery.

Hallux valgus (HV) presents as a common forefoot deformity that causes problems with pain, mobility, footwear, and quality of life. The most common open correction used in the UK is the Scarf and Akin osteotomy, which has good clinical and radiological outcomes and high levels of patient satisfaction when used to treat a varying degrees of deformity. However, there are concerns regarding recurrence rates and long-term outcomes.

TPC2 controls MITF expression and metastasis in melanoma.

Recent findings by Abrahamian et al. (2024) provides new insights into the relationship between Two Pore Channel 2 (TPC2) activity and the development and progression of melanoma. Melanocyte inducing transcription factor (MITF) is a critical regulator of both melanocyte and melanoma behavior.

Synaptic alterations in pyramidal cells following genetic manipulation of neuronal excitability in monkey prefrontal cortex.

The dorsolateral prefrontal cortex (DLPFC) plays a crucial role in primate cognition, integrating multimodal information to generate top-down signals for cognitive control. During cognitive tasks, the DLPFC displays activity patterns of exceptional complexity and duration not observed in other cortical areas or species. These activity patterns are likely associated with the unique physiological and morphological properties of primate DLPFC pyramidal neurons (PNs).

Copper(II)-Catalyzed Enantioselective Addition of Aryl Amines to Isatin-Derived -Boc-Ketimines for the Synthesis of Acyclic ,'-Ketals.

Here, we demonstrated a copper(II)-catalyzed enantioselective addition of aryl amines to isatin-derived -Boc-ketimines using chiral O-N-N tridentate ligands derived from BINOL and proline. Generally, the chiral acyclic ,'-ketals were obtained in high yields (up to 98%) and excellent ee values (up to 98%). Various aryl amines could be tolerated and a gram-scale reaction was also possible.
