Saving money and spending carefully are generally considered good financial habits. But what happens when they turn into obsessive extremes? Radhika Sanghani speaks to people whose money fears have taken over their lives

Virtual reality (VR) is increasingly used for assessment in educational and clinical settings. However, users’ immersive competence (IC)—the ability to navigate and operate VR systems—may introduce bias unrelated to clinical skills or patient functioning. In this randomized controlled trial, 88 medical students received either general IC training, general+specific IC training, or no structured training before completing a VR-based assessment scenario. Multimodal data were collected, including electrodermal activity, cognitive-load ratings, procedural efficiency, and usability barriers. Specific IC training improved performance compared with control (28.3% ± 10.3% vs. 21.2% ± 10.8%, p = 0.010, d = 0.67), moderated by procedural efficiency and increased cognitive load. Prior 3D experience did not predict performance in the control group, likely due to a floor effect, but did in the specific training group. These findings indicate that IC is a causal, modifiable factor in VR-based assessments and should be considered to ensure fair and valid evaluations.

Ignoring a chronic cough can lead to numerous complications. In particular, chronic coughing can result in pain in your throat, muscle pain in your chest, headaches, lack of sleep, and feelings of fatigue. In some cases, chronic coughing may lead to vomiting or rupture of small blood vessels located behind your eyes.

Air pollution is a major environmental health risk, yet its cognitive impact remains under-recognised. Evidence links short- and long-term fine particulate matter (PM2.5) exposure to reduced cognitive performance and intelligence quotient (IQ). We estimate global PM2.5-related IQ losses of 65 billion points, disproportionately affecting low- and lower-middle-income countries. Current air quality standards may not protect neurological health; this threat to global intellect requires nuanced regulation, targeted mitigation, and cross-sectoral policy.

AIOCD directive comes at a time when semaglutide, one of the global blockbuster GLP-1 drug sold by Danish drug major Novo Nordisk under brand names such as Ozempic and Wegovy, is going off patent in India later this month.

Multiple myeloma (MM) is a plasma cell malignancy frequently complicated by renal impairment, which substantially worsens prognosis. Although therapeutic advances have improved MM survival, renal failure remains a major contributor to adverse outcomes. This study examined long-term trends and demographic disparities in mortality among U.S. decedents with MM listed as the underlying cause of death and renal failure listed as a contributing cause. Mortality data for adults aged ≥ 45 years from 1999 to 2023 were obtained from the CDC Wide-ranging Online Data for Epidemiologic Research (WONDER) database. Deaths were identified using ICD-10 codes, with MM (C90.0) as the underlying cause and renal failure (N17–N19) as a contributing cause. Age-adjusted mortality rates (AAMRs) and crude mortality rates (CMRs) were calculated by sex, race/ethnicity, region, age group, and urbanization level. Temporal trends were evaluated using Joinpoint regression to estimate annual percent change (APC) and average annual percent change (AAPC). Overall mortality declined from 1999 to 2023, with the AAMR decreasing from 2.39 to 1.60 per 100,000 population (AAPC: −1.30). Despite this improvement, substantial disparities persisted. Males consistently exhibited higher AAMRs than females. Non-Hispanic Black individuals had the highest race-specific mortality rates. Residents of nonmetropolitan areas and those living in the Midwest experienced persistently higher mortality. Age-stratified analyses showed declining trends in most age groups, while adults aged ≥ 85 years demonstrated a modest recent increase. Mortality among U.S. adults with MM listed as the underlying cause of death and renal failure as a contributing cause declined between 1999 and 2023. However, persistent disparities by sex, race/ethnicity, region, urbanization, and age remain. These findings highlight the need for targeted strategies to reduce the burden of renal complications among high-risk MM populations.

Health - Antenatal Care: The Science of Preventing Problems Before They Become Emergencies

Hepatitis B virus (HBV) infections are associated with an increased risk of B-cell lymphomas, including follicular lymphoma (FL). Chronic HBV infection and shifts in infection status following treatment can influence lymphomagenesis and immune reprogramming, potentially affecting clinical outcomes. Using the CosMx Spatial Molecular Imaging, after integrated with dynamic HBV infection states and duration of overt infection, this refines four recurrent patterns, especially memory B cell-like malignant cells (MBLM) subtype (PTPRCAP + ) that is traced with atypical features and latent indolence, and virus protein transport-related follicular dendritic cell (FDC) which shows interplay with MBLM. Except for virus-induced immune exhaustion, distinct contributions to POD24 occurrence from malignant cells and immunosuppressive cell communities under distinct HBV infection states are discerned such as through CCL21/CCR7 signaling pathway. Taken together, our spatial multicellular dynamics reveal an increased prevalence of MBLM and variable FDC phenotypes which is associated with POD24 occurrence in HBV-related FL tumors. Spatial Molecular Imaging illustrated memory B cell-like malignant cells subtype (PTPRCAP + ) that was interacted with virus protein transport-related follicular dendritic cell acted as culprit for the early-relapsed follicular lymphoma.
