Background: The study of ADHD has predominantly focused on individual-level risk-factors, and less is known about contextual factors that promote adaptive functioning.

Aims: The present study is the first to evaluate the longitudinal association between five dimensions of school climate (academic expectations, student engagement, disciplinary structure, respect for students, willingness to seek help) and student outcomes, and whether ADHD symptom severity moderates those associations.

Methods And Procedures: Participants included 274 adolescents (45 % female) who completed assessments in 8th (T1) and 10th (T2) grades.

Lyme disease is the most common vector-borne disease in the United States. Recent environmental and socioecological changes have led to an increased incidence of Lyme and other tick-borne diseases, which enhances the urgency of identifying and mitigating adverse outcomes of Lyme disease exposure. Lyme disease during pregnancy, especially when untreated, may lead to adverse pregnancy and neonatal outcomes; however, long-term child outcomes following utero exposure to Lyme disease have not yet been systematically assessed.

Neuropeptide FF (NPFF) is an endogenous octapeptide that was originally isolated from the bovine brain. It belongs to the RFamide family of peptides that has a wide range of physiological functions and pathophysiological effects. NPFF and its receptors, NPFFR1 and NPFFR2, abundantly expressed in rodent and human brains, participate in cardiovascular regulation.

Ultrasound modulation of melatonin release from pineal glands in vitro.

Ultrasonics

January 2025

Department of Biomedical Engineering, The George Washington University, 800 22 nd St. NW Suite 5000, Washington, DC 20052, United States of America. Electronic address:

Objectives: In this study, we aim to investigate whether therapeutic ultrasound can modulate the release of melatonin from the pineal gland-either increasing or decreasing its levels-and to assess the safety of this technique. This research could address a significant clinical need by providing a noninvasive method to potentially regulate sleep and circadian rhythms through the targeted modulation of melatonin.

Methods: Rat pineal glands were placed in a well with a Krebs Ringer Buffer solution.

Metoprolol vs diltiazem for atrial fibrillation with rapid ventricular rate: Systematic review and meta-analysis of adverse events.

Am J Emerg Med

December 2024

Department of Emergency Medicine, University of Maryland School of Medicine, Baltimore, MD, USA; Departments of Pharmacy and Emergency Medicine, University of Rochester Medical Center, Rochester, New York, USA. Electronic address:

Background: Intravenous (IV) diltiazem and metoprolol are commonly used to achieve rate control for atrial fibrillation with RVR (Afib with RVR), and are both recommended as first-line by current guidelines. While prior studies investigated the efficacy of these medications, there is little evidence available regarding the risk of adverse events (AEs) with their use.

Methods: We identified randomized controlled trials (RCT) and observational studies reporting rates of AEs following administration of IV diltiazem and metoprolol for Afib with RVR by searching PubMed, SCOPUS, EMBASE, and Cochrane Library.

Background: Lebrikizumab monotherapy significantly improved signs and symptoms in patients with moderate-to-severe atopic dermatitis (AD) in phase 3 Advocate1 and ADvocate2 studies.

Objective: To evaluate improvements in patient-reported symptoms and quality-of-life (QoL) measures by Eczema Area and Severity Index (EASI) response categories using pooled Advocate1 and ADvocate2 data (post hoc analysis).

Methods: In the 52-week (W) (16-W induction + 36-W maintenance) double-blind, placebo-controlled ADvocate1 and ADvocate2 studies, patients were randomized (2:1) to receive subcutaneous lebrikizumab 250 mg or placebo every 2 weeks.

Cervical synovial cysts are rare, especially hemorrhagic cervical synovial cysts. The patient was a 58-year-old male with a five-month history of tingling in his right shoulder region, radicular pain in his right arm, and increased pain on the right chest wall that worsened with lying supine down. The patient was diagnosed with a right-sided hemorrhagic synovial cyst at the C7-T1 level.

Purpose: Continuous EEG (cEEG) monitoring is increasingly used in the management of neonates with seizures. There remains debate on what clinically relevant information can be gained from cEEG in neonates with suspected seizures, at high risk for seizures, or with definite seizures, as well as the use of cEEG for prognosis in a variety of conditions. In this guideline, we address these questions using American Clinical Neurophysiology Society structured methodology for clinical guideline development.

Background: Febrile young infants are at risk of invasive bacterial infections (IBIs; bacteremia or bacterial meningitis). American Academy of Pediatrics (AAP) guidelines recommend that when procalcitonin testing is unavailable, C-reactive protein (CRP), absolute neutrophil count (ANC) and temperature should be used to identify low-risk infants. We sought to determine the optimal combination of these inflammatory markers to predict IBI when procalcitonin is unavailable.

Article Synopsis
  • The study analyzes the envelope (E) protein of SARS-CoV-2, highlighting its importance in viral assembly, release, and overall virulence, while assessing the conservation and mutation patterns across different variants of concern (VOCs).
  • Mutations were identified in various strains, notably B.1.351 and Omicron, that could compromise the effectiveness of current diagnostic RT-PCR assays by altering the E protein's stability.
  • The research underscores the need for ongoing surveillance of viral mutations to enhance diagnostic strategies and understand the evolving nature of SARS-CoV-2.

Genetic variants of accessory proteins and G proteins in human genetic disease.

Crit Rev Clin Lab Sci

January 2025

Institute of Metabolism and Systems Research (IMSR), University of Birmingham, Birmingham, West Midlands, UK.

We present a series of three articles on the genetics and pharmacogenetics of G protein- coupled receptors (GPCR). In the first article, we discuss genetic variants of the G protein subunits and accessory proteins that are associated with human phenotypes; in the second article, we build upon this to discuss "G protein-coupled receptor (GPCR) gene variants and human genetic disease" and in the third article, we survey "G protein-coupled receptor pharmacogenomics". In the present article, we review the processes of ligand binding, GPCR activation, inactivation, and receptor trafficking to the membrane in the context of human genetic disease resulting from pathogenic variants of accessory proteins and G proteins.
