Previous research suggests that an eyewitness credibility bias can arise when mock jurors are informed of a child's disability diagnosis. The aim of the present study was to examine mock jurors' lie-detection accuracy and credibility perceptions when assessing eyewitness testimonies provided by children diagnosed with an intellectual disability. Adult mock jurors (N = 217; half informed of the child's disability status) read four transcriptions from interviews with children (ages 10 to 15) diagnosed with an intellectual disability before evaluating the credibility and truthfulness of each eyewitness report.

Background: Myeloproliferative neoplasms (MPNs) are a group of chronic disorders of the bone marrow characterised by the overproduction of clonal myeloid stem cells. The most common driver mutation found in MPNs is a point mutation on exon 14 of the JAK2 gene, JAK2. Various studies have suggested that measuring the variable allele frequency (VAF) of JAK2 may provide useful insight regarding diagnosis, treatment, risks and outcomes in MPN patients.

Article Synopsis
  • The study aimed to investigate whether the quality of hospitals before the pandemic influenced the survival rates of Medicare patients hospitalized with COVID-19.
  • Researchers analyzed in-hospital and 30-day mortality rates in relation to pre-pandemic hospital quality, finding that better-rated hospitals had significantly lower mortality rates.
  • Results showed that patients in lower-rated hospitals, specifically those with one star, faced much higher odds of dying either during their hospital stay or within 30 days of discharge compared to those in five-star hospitals.

In 2018, the Food and Drug Administration expanded the age of eligibility for the human papillomavirus (HPV) vaccine to 27 to 45 years. However, it is unclear if there are racial/ethnic disparities in HPV vaccine uptake for this age-group following this expanded recommendation. We aimed to identify any disparities in HPV vaccine in 27 to 45 year-olds based on sociodemographic factors.

Importance: Accurate risk prediction of morbidity and mortality in patients with heart failure with preserved ejection fraction (HFpEF) may help clinicians risk stratify and inform care decisions.

Objective: To develop and validate a novel prediction model for clinical outcomes in patients with HFpEF using routinely collected variables and to compare it with a biomarker-driven approach.

Design, Setting, And Participants: Data were used from the Dapagliflozin Evaluation to Improve the Lives of Patients With Preserved Ejection Fraction Heart Failure (DELIVER) trial to derive the prediction model, and data from the Angiotensin Receptor Neprilysin Inhibition in Heart Failure With Preserved Ejection Fraction (PARAGON-HF) and the Irbesartan in Heart Failure With Preserved Ejection Fraction Study (I-PRESERVE) trials were used to validate it.

Background: Rapidly accelerated fibrosarcoma B-type (BRAF) and mitogen-activated extracellular signal-regulated kinase (MEK) inhibitors have revolutionized treatment for patients with BRAF-mutated melanoma. Although left ventricular systolic dysfunction associated with these therapies has been reported in clinical trials, the real-world incidence is poorly defined, as are risk factors for its development.

Objectives: This study sought to characterize the incidence, time course, and risk factors for cancer therapy-related cardiac dysfunction (CTRCD) in patients with melanoma receiving BRAF and MEK inhibitors.

Aims: Neuropeptide Y (NPY) is the most abundant neuropeptide found in the heart and is released alongside norepinephrine following prolonged sympathetic activation, a process that is implicated in the pathophysiology of heart failure (HF). In patients with severely impaired left ventricular ejection fraction (LVEF) undergoing cardiac resynchronization therapy, higher levels of NPY measured in coronary sinus blood, are associated with poorer outcome. The aim was to examine the association of peripheral venous NPY levels and outcomes in a HF population with a range of LVEF, using a highly sensitive and specific assay.

Purpose: Object naming requires visual decoding, conceptualization, semantic categorization, and phonological encoding, all within 400 to 600 ms of stimulus presentation and before a word is spoken. In this study, we sought to predict semantic categories of naming responses based on prearticulatory brain activity recorded with scalp EEG in healthy individuals.

Methods: We assessed 19 healthy individuals who completed a naming task while undergoing EEG.

Article Synopsis
  • * In the PARAGON-HF study, patients with left ventricular ejection fraction of ≥45% were analyzed, showing that higher RDW levels were linked to worse clinical outcomes, including increased hospitalizations and cardiovascular deaths.
  • * The study found that sacubitril/valsartan reduced RDW more effectively than valsartan over 48 weeks, adding valuable prognostic information to existing predictors without changing the effects based on initial RDW levels.

The Child Asthma Risk Assessment Tool (CARAT) identifies risk factors for asthma morbidity. We hypothesized that CARAT-identified risk factors (using a CARAT adapted for inpatient use) would be associated with future healthcare utilization and would identify areas for intervention. We reviewed CARAT data collected during pediatric asthma admissions from 2010-2015, assessing for risk factors in environmental, medical, and social domains and providing prompts for inpatient (specialist consultation or social services engagement) and post-discharge interventions (home care visit or home environmental assessment).

Aims: It is uncertain how much candidate biomarkers improve risk prediction when added to comprehensive models including routinely collected clinical and laboratory variables in heart failure.

Methods And Results: Aldosterone, cystatin C, high-sensitivity troponin T (hs-TnT), galectin-3, growth differentiation factor-15 (GDF-15), kidney injury molecule-1, matrix metalloproteinase-2 and -9, soluble suppression of tumourigenicity-2, tissue inhibitor of metalloproteinase-1 (TIMP-1) and urinary albumin to creatinine ratio were measured in 1559 of PARADIGM-HF participants. We tested whether these biomarkers, individually or collectively, improved the performance of the PREDICT-HF prognostic model, which includes clinical, routine laboratory, and natriuretic peptide data, for the primary endpoint and cardiovascular and all-cause mortality.
