Background: Understanding the association of tobacco product use with subclinical markers is essential in evaluating health effects to inform regulatory policy. This is particularly relevant for noncigarette products (eg, cigars, pipes, and smokeless tobacco), which have been understudied because of their low prevalence in individual cohort studies.
Methods: This cross-sectional study included 98 450 participants from the Cross-Cohort Collaboration-Tobacco data set.
Abdominal wall endometriosis (AWE) is a clinical disorder with unknown pathogenesis with an incidence between 0.03% and 1% in women affected by cutaneous/scar endometriosis. We investigated the pathological, molecular cytogenetic and cell proliferation features of a primary AWE developed in rectus abdominis muscle in a patient without co-existing pelvic endometriosis.

Using a computational approach, we designed variants of SARS-CoV-2 RBDs and selected 7 natural sarbecovirus RBDs, each predicted to fold properly and abrogate antibody responses to variable epitopes. RBDs were attached to 60-mer nanoparticles to make immunogens displaying two (mosaic-2s), five (mosaic-5), or seven (mosaic-7) different RBDs for comparisons with mosaic-8b, which elicited cross-reactive antibodies and protected animals from sarbecovirus challenges.

How sensitization in the first pregnancy influences this phenomenon in a subsequent pregnancy is unclear. Accordingly, this study determined whether maternal-newborn ABO blood group incongruence in a first pregnancy further modifies the risk of serious infection in a subsequent pregnancy marked by ABO incongruency.

To assess the effects of a microscale/nanoscale (MN) topography, this study compared the effects of MN-modified, anodized, and smooth Ti6Al4V surfaces on MSC response, and for the first time, directly contrasted MN-induced osteoblast differentiation with culture on tissue culture polystyrene (TCPS) in osteogenic medium (OM). Surface characterization revealed distinct differences in microroughness, composition, and topography among the Ti6Al4V substrates.

Objectives: This work aimed to study the genetic etiology causing absence of spontaneous pubertal development, hypergonadotropic hypogonadism, and primary amenorrhea in 2 sisters.
Methods: Whole-exome sequencing was performed on DNA extracted from peripheral lymphocytes of 2 Palestinian sisters born to consanguineous parents.
Background: We developed a United States-based real-world data resource to better understand the continued impact of the coronavirus disease 2019 (COVID-19) pandemic on immunocompromised patients, who are typically underrepresented in prospective studies and clinical trials.
Methods: The COVID-19 Real World Data infrastructure (CRWDi) was created by linking and harmonizing de-identified HealthVerity medical and pharmacy claims data from 1 December 2018 to 31 December 2023, with severe acute respiratory syndrome coronavirus 2 virologic and serologic laboratory data from major commercial laboratories and Northwell Health; COVID-19 vaccination data; and, for patients with cancer, 2010 to 2021 National Cancer Institute Surveillance, Epidemiology, and End Results registry data.
Results: The CRWDi contains 4 cohorts: patients with cancer; patients with rheumatic diseases receiving pharmacotherapy; noncancer solid organ and hematopoietic stem cell transplant recipients; and people from the general population including adults and pediatric patients.
Objectives: International guidelines recommend integrase strand-transfer inhibitor (INSTI)-based regimens as initial and switch therapy in people with HIV. As novel INSTIs become available, understanding how emergence of resistance at virological failures and seroconversions affects subsequent treatment options is needed. For the latest approved INSTI, cabotegravir, resistance patterns comprising Q148K/R, N155H, R263K, G118R, E138A/K and G140A/S (alone or in combination) have been documented in virological failures and seroconversions.

Objective: To compare quality and efficiency measures under 2 payment models: at-risk MA and fee-for-service (FFS) MA.
The field of artificial intelligence (AI) has entered a new cycle of intense opportunity, fueled by advances in deep learning, including generative AI. Applications of recent advances affect many aspects of everyday life, yet nowhere is it more important to use this technology safely, effectively, and equitably than in health and health care. Here, as part of the National Academy of Medicine's Vital Directions for Health and Health Care: Priorities for 2025 initiative, which is designed to provide guidance on pressing health care issues for the incoming presidential administration, we describe the steps needed to achieve these goals.

If their transcatheter heart valve degenerates later in life, most will hope to undergo redo-TAVR. However, if redo-TAVR is not feasible, some may have to undergo surgical explantation of their transcatheter heart valve (TAVR-explant).

The metabolic work-up was significant for an elevated bone fraction of alkaline phosphatase isoenzymes, and high bone turnover markers, including fasting C- telopeptide (CTX). A diagnosis of Paget's disease of bone (PDB) was considered.

Background: Food and Drug Administration-mandated postmarket studies for transcatheter aortic valve replacement in low-risk populations plan to use passively collected registry data linked to claims for long-term follow-up out to 10 years. Therefore, it is critically important to understand the validity of these claims-based end points. We sought to evaluate the ability of administrative claims with () codes to identify trial-adjudicated end points and reproduce treatment comparisons of aortic valve replacement in the Evolut Low Risk Trial.

In this study, we evaluated safety outcomes in 783 patients over more than 2,200 total patient-years of observation from 38 T cell therapy trials. The trials employed integrating gammaretroviral or lentiviral vectors to deliver engineered receptors to target HIV-1 infection or cancer.

Most LHSs operate within a specific healthcare system, typically hospital-based, under a common electronic health record (EHR) and management structure. The Early Psychosis Intervention Network in Texas (EPINET-TX) is a novel case study of a developing LHS across 16 independent community mental health clinics operating state-funded coordinated specialty care (CSC) programs for early psychosis.

Methods: ETNA-VTE Europe is a prospective, noninterventional, post-authorization study in unselected patients with VTE treated with edoxaban in eight European countries for up to 18 months. Recurrent VTE, major bleeding, and all-cause death were the primary study outcomes.
Emotions play a significant role in well-being and interpersonal relationships. The presence of others is indispensable in facilitating the regulation of an individual's emotions. Despite extensive research on intrinsic emotion regulation strategies, the specific strategies employed during extrinsic emotion regulation (EER), particularly among individuals with depression, remain underexplored.

AHSCT after failure of high-efficacy DMT in aggressive forms of relapsing-remitting MS is a generally accepted indication, yet the optimal placement of this approach in the treatment sequence is not universally agreed upon. Uncertainties also remain with respect to other indications, such as in rapidly evolving, severe, treatment-naive MS, progressive MS, and neuromyelitis optica spectrum disorder (NMOSD).

Methods: Patients with newly diagnosed CD were recruited and followed prospectively. MED adherence was assessed by repeated food frequency questionnaires (FFQ), using a predefined IBDMED score, alongside validated MED adherence screeners.
Background: The clinical course of myelin oligodendrocyte glycoprotein (MOG) antibody-associated disease (MOGAD) is variable. However, robust markers of poor outcome and/or relapse risk are still missing.
Objective: To evaluate the frequency of cerebrospinal fluid-restricted oligoclonal bands (CSF-OCB) in a national cohort of adult MOGAD patients and to assess their prognostic value for the risk of relapse and severity.
Background: Sepsis-associated encephalopathy (SAE) may be worsened by early systemic insults. We aimed to investigate the association of early systemic insults with outcomes of critically ill patients with severe SAE.
Methods: We performed a retrospective analysis using data from the French OUTCOMEREA prospective multicenter database.

Purpose: Intravitreal injections of anti-VEGF agents are considered as safe, with a very low rate of intraocular inflammations (IOI). Faricimab is a novel intravitreal bispecific antibody targeting both VEGF-A and angiopoietin-Tie2 independently. Despite a safe profile in randomized clinical trials, several real-life studies have reported cases of IOI.
