Article Synopsis
  • The study investigates CP symmetry violation in the decay of D^{+} particles into K^{-}K^{+}π^{+} using data from proton-proton collisions at a high energy of 13 TeV.
  • A unique model-independent method was employed to analyze the phase-space distributions of D^{+} and D^{-} particles, correcting for any instrumental biases using D_{s}^{+} decays.
  • The findings indicate no significant evidence of CP violation, with a p value of 8.1%, and measure specific CP asymmetry observables, marking this study as the most sensitive search of its kind in multibody decays.

Cognitive control develops throughout adolescence, a high-risk period for bipolar disorders (BD) onset. Despite neurobehavioral abnormalities in adults with BD, there is minimal research investigating deviations in cognitive control in adolescents with BD. Cognitive control involves numerous processes.

The epidemiological data regarding mortality rates of adults with sarcoidosis and non-ischemic cardiovascular disease (CVD) are limited. A retrospective observational analysis was conducted to identify trends and disparities related to sarcoidosis and non-ischemic cardiovascular disease mortality among the adult US population from 1999 to 2022. We used the Centers for Disease Control and Prevention (CDC) WONDER database to extract death certificate data for the adult US population (≥25 years).

Despite the significant advances made involving the additive manufacturing (AM) of metals, including those related to both materials and processes, challenges remain in regard to the rapid qualification and insertion of such materials into applications. In general, understanding the process-microstructure-property interrelationships is essential. To successfully understand these interrelationships on a process-by-process basis and exploit such knowledge in practice, leveraging monitoring, modeling, and statistical analysis is necessary.

Background: Veno-venous extracorporeal membrane oxygenation (VV-ECMO) is a supportive therapy for acute respiratory failure with increased risk of packed red blood cells (PRBC) transfusion. Blood cell salvage (BCS) aims to reduce blood transfusion, but its efficacy is unclear. This study aimed to estimate the effect of BCS at the time of removal of the ECMO circuit (ECMO decannulation) on PRBC transfused.

Background: Respiratory syncytial virus (RSV) is the leading cause of acute lower respiratory illness among young children. Human immunodeficiency virus (HIV)-exposed, uninfected (HEU) children experience a higher burden of RSV disease and have immune abnormalities that may influence their responses to live-attenuated RSV vaccines.

Methods: In a pooled analysis of clinical trials of 7 live-attenuated, intranasal RSV vaccines conducted by the IMPAACT Network among children 6 to <25 months of age with serum RSV-neutralizing titers of <1:40, the infectivity and immunogenicity of these vaccines were compared among HEU and HIV-unexposed, uninfected (HUU) children.

Article Synopsis
  • Replication forks encountering unrepaired single-strand breaks (SSBs) can lead to both single-ended (seDSBs) and double-ended double-strand breaks (deDSBs), which are significant in cancer development.
  • The study reveals that in fission yeast, SSBs typically result in deDSBs repaired by homologous recombination, but can also initiate break-induced replication (BIR).
  • The occurrence of BIR is more frequent when DNA replication fork convergence is delayed and the Ku70 protein, involved in non-homologous end joining, is absent.

Background: Echocardiography, cardiac magnetic resonance and cardiac fluorodeoxyglucose positron emission tomography (FDG-PET) imaging play key roles in the diagnosis and management of cardiac sarcoidosis (CS), but the relative value of each modality in predicting outcomes has yet to be determined. This study sought to determine the prognostic importance of multimodality imaging data over and above demographic characteristics and left ventricular ejection fraction (LVEF).

Methods: Consecutive patients newly diagnosed with CS were included.

Background: Cardiac Resynchronisation Therapy (CRT) has demonstrated short and long-term benefit in heart failure with reduced ejection fraction (HFrEF), including ischaemic (ICM) and non-ischaemic cardiomyopathy. However, there is a paucity of evidence regarding its role in cardiac sarcoidosis (CS).

Methods: Consecutive CS patients with CRT and baseline left ventricle ejection fraction (LVEF)≤40 referred to one specialist hospital in London between November 2008-March 2023 were retrospectively reviewed.

Aims: In cardiac sarcoidosis (CS) patients, the benefit of cardiac resynchronization therapy (CRT) remains unclear. We sought to assess the short-term and long-term effects of CRT in CS patients with a range of left ventricular (LV) ejection fractions (LVEFs).

Methods: Consecutive CS patients with heart failure with reduced ejection fraction (HFrEF; LVEF ≤ 40%), mildly reduced ejection fraction (HFmrEF; LVEF 41%-49%) and preserved ejection fraction (HFpEF; LVEF ≥ 50) treated with CRT under the care of a tertiary UK centre between 2008 and 2023 were reviewed.

Metabolic Syndrome (MS) is a cluster of metabolic risk factors, characterized by abdominal obesity, dyslipidemia, hypertension, insulin resistance, among others. The purpose of the study was to evaluate the astaxanthin (AXT) effects extracted from freshwater crab (Dilocarcinus pagei) at the Paraná Basin on lipotoxicity, lipid peroxidation and oxidative stress in the kidney of rats fed with a sucrose-rich diet (SRD). We hypothesized that daily administration of AXT prevents kidney damage by reducing lipotoxicity, lipid peroxidation, and reactive oxygen species (ROS), and by improving antioxidant enzyme defenses and crosstalk between NrF2 and NF-ĸB transcription factors.

  • The Obstetric Bleeding Study UK (OBS UK) is a randomized controlled trial aimed at addressing postpartum hemorrhage, initially developed in Wales, which has noted improved maternal outcomes but faces limitations in generalizability due to demographic homogeneity in the Welsh sample.* -
  • To enhance the diversity and inclusivity of the trial, maternity units across the UK were selected based on their representation of various ethnic and socioeconomic profiles, with a focus on ensuring results are applicable to a broader population.* -
  • An interactive dashboard was created using census data to visualize and compare the demographics of each participating maternity unit, confirming that the trial sites reflect the wider UK's ethnic and socioeconomic diversity, despite some inconsistencies in data availability across different locations.*

Article Synopsis
  • This review talks about how the liver helps protect the body and what happens when it doesn't work right, especially in diseases.
  • It explains how the liver can normally stay calm and not cause problems, but can get confused and become reactive in chronic liver diseases.
  • The review will also look at liver transplants, why the body might reject a new liver, and how autoimmune diseases can make the liver attack itself.

Globally, there has not been a standardised approach to ensure that the growing number of people who are not licensed clinicians but are delivering psychological interventions and mental health services have the competencies to deliver those interventions and services safely. Therefore, WHO and UNICEF developed Ensuring Quality in Psychosocial and Mental Health Care (EQUIP). EQUIP is a free resource with a digital platform that can be used to guide competency assessment.

Multivariate machine learning techniques are a promising set of tools for identifying complex brain-behavior associations. However, failure to replicate results from these methods across samples has hampered their clinical relevance. Here we aimed to delineate dimensions of brain functional connectivity that are associated with child psychiatric symptoms in two large and independent cohorts: the Adolescent Brain Cognitive Development (ABCD) Study and the Generation R Study (total n = 6935).
