Gamma oscillations and excitation/inhibition imbalance: parallel effects of N-methyl D-aspartate receptor antagonism and psychosis.

Background: Auditory steady-state response (ASSR) abnormalities in the 40-Hz (gamma band) frequency have been observed in schizophrenia and rodent studies of N-methyl D-aspartate glutamate receptor (NMDAR) hypofunction. However, the extent to which 40-Hz ASSR abnormalities in schizophrenia resemble deficits in 40-Hz ASSR induced by acute administration of ketamine, an NMDAR antagonist, is not yet known.

Methods: To address this knowledge gap, we conducted parallel EEG studies: a crossover, placebo-controlled ketamine drug challenge study in healthy subjects (Study 1) and a comparison of patients with schizophrenia and healthy controls subjects (Study 2).

Changes in weight and physical function for older African American women in Take Off Pounds Sensibly (TOPS): Study protocol for a randomized clinical trial.

Breastfeeding Among First-Time Mothers Reporting Housing Insecurity and Food Insecurity.

Despite health benefits to both infants and mothers, many are not breastfeeding as recommended by national guidelines. Prior studies examining the effects of housing insecurity and food insecurity on breastfeeding intention and duration have been limited and yielded mixed findings. To assess the relationship among housing insecurity, food insecurity, and breastfeeding, we conducted a secondary analysis of a cohort of nulliparous U.

Palatal segment contributions to midfacial anterior-posterior growth.

Anterior-posterior (A-P) elongation of the palate is a critical aspect of integrated midfacial morphogenesis. Reciprocal epithelial-mesenchymal interactions drive secondary palate elongation that is coupled to the periodic formation of signaling centers within the rugae growth zone (RGZ). However, the relationship between RGZ-driven morphogenetic processes, the differentiative dynamics of underlying palatal bone mesenchymal precursors, and the segmental organization of the upper jaw has remained enigmatic.

Multi-Institutional Analysis of Pancreatoduodenectomy for Nonfamilial Periampullary Adenoma: A Novel Risk Score to Guide Shared Decision-Making.

Introduction: Pancreatoduodenectomy (PD) may occasionally be indicated for complete removal of periampullary (duodenal and ampullary) adenomas (PAs). As compared with malignant indications, PD for benign or pre-malignant disease is often associated with increased morbidity. While the Spigelman classification assesses malignancy risk for familial adenomatous polyposis (FAP)-related duodenal adenomas, no malignancy risk score (MRS) exists for non-FAP related PAs.

Facilitators and barriers of alcohol goals for Latinx men hospitalized with alcohol use disorder seen by an Addiction Consult Team.

Introduction: Latinx individuals are disproportionately affected by alcohol use disorder (AUD). Understanding Latinx individuals' barriers and facilitators to reach AUD-related goals can help implement culturally and linguistically concordant interventions to improve alcohol-related outcomes.

Methods: We conducted semi-structured qualitative interviews with Latinx, Spanish-speaking men with AUD within 20 weeks of hospital discharge who were seen by an addiction consult team during hospitalization in an urban, safety-net hospital in San Francisco.

Engineered initiator tRNAs can effectively start translation at non-AUG start codons and diversify N-terminal amino acids for mRNA Display.

mRNA display is an effective tool to identify high-affinity macrocyclic binders for challenging protein targets. The success of an mRNA display selection is dependent on generating highly diverse libraries with trillions of peptides. While translation elongation can canonically accommodate the 61 proteinogenic triplet codons, translation initiation is restricted to the native start codon AUG.

Consensus Recommendations for the Management of Neurosarcoidosis: A Delphi Survey of Experts Across the United States.

Background And Objectives: Neurosarcoidosis poses a diagnostic and management challenge due to its rarity, phenotypic variability, and lack of randomized controlled studies to guide treatment selection. Recommendations for management based on expert opinion are useful in clinical practice and provide a framework for designing prospective studies.

Methods: In this Delphi survey study, specialists with experience in managing patients with neurosarcoidosis were invited to anonymously complete 2 surveys about key elements of evaluation, diagnosis, treatment, monitoring, and long-term management of neurosarcoidosis.

De novo and inherited dominant variants in U4 and U6 snRNAs cause retinitis pigmentosa.

The U4 small nuclear RNA (snRNA) forms a duplex with the U6 snRNA and, together with U5 and ~30 proteins, is part of the U4/U6.U5 tri-snRNP complex, located at the core of the major spliceosome. Recently, recurrent variants in the U4 RNA, transcribed from the gene, and in at least two other genes were discovered to cause neurodevelopmental disorder.

Artificial Intelligence in Pancreatic Intraductal Papillary Mucinous Neoplasm Imaging: A Systematic Review.

Background: Based on the Fukuoka and Kyoto international consensus guidelines, the current clinical management of intraductal papillary mucinous neoplasm (IPMN) largely depends on imaging features. While these criteria are highly sensitive in detecting high-risk IPMN, they lack specificity, resulting in surgical overtreatment. Artificial Intelligence (AI)-based medical image analysis has the potential to augment the clinical management of IPMNs by improving diagnostic accuracy.

Longitudinal Measures of Cardiovascular Risk Factors Are Associated with Subfertility in the Coronary Artery Risk Development in Young Adults (CARDIA) Study.

Introduction: Previous reports have noted associations between subfertility in women and increased risk of cardiovascular disease (CVD) events in later life. However, reports conflict regarding the associations between subfertility and CVD risk factors. Using data from a population-based cohort of Black and White women, we examined the association between longitudinal assessments of CVD risk factors and subfertility.

Inequalities in access to health care: an exploration of the cascade of care for in-transit migrants and asylum seekers, and the general population in Mexico.

Background: All over the world, migrants experience inequalities in access to health care. While this issue has been amply explored among immigrants and refugees in high-income countries, there is a dart of information on the situation of in-transit migrants and asylum seekers (IMAS) in low- or middle-income countries. Since these are the main recipient countries for this population, it is important to document inequalities in access to care in this context, especially for countries such as Mexico, in which IMAS are entitled to health care in par with the general population.

A gut pathobiont regulates circulating glycine and host metabolism in a twin study comparing vegan and omnivorous diets.

Metabolic diseases such as type 2 diabetes and obesity pose a significant global health burden. Plant-based diets, including vegan diets, are linked to favorable metabolic outcomes, yet the underlying mechanisms remain unclear. In a randomized trial involving 21 pairs of identical twins, we investigated the effects of vegan and omnivorous diets on the host metabolome, immune system, and gut microbiome.

Beyond Size and Class Balance: Alpha as a New Dataset Quality Metric for Deep Learning.

In deep learning, achieving high performance on image classification tasks requires diverse training sets. However, the current best practice-maximizing dataset size and class balance-does not guarantee dataset diversity. We hypothesized that, for a given model architecture, model performance can be improved by maximizing diversity more directly.
