Objectives: The objectives of this study were to analyze trends in prostate cancer incidence, incidence, mortality, and disability-adjusted life years (DALYs) from 1990 to 2021 via data from the Global Burden of Disease (GBD) study in South Asia. Additionally, the study projects future prostate cancer incidence rates up to 2031 to inform public health interventions in South Asia.

Methods: Data covering South Asian countries such as Bangladesh, Bhutan, India, Nepal, and Pakistan were obtained from the GBD 2021 portal.

Background: The effect of a liberal red-cell transfusion strategy as compared with a restrictive strategy in patients during the critical care period after an aneurysmal subarachnoid hemorrhage is unclear.

Methods: We randomly assigned critically ill adults with acute aneurysmal subarachnoid hemorrhage and anemia to a liberal strategy (mandatory transfusion at a hemoglobin level of ≤10 g per deciliter) or a restrictive strategy (optional transfusion at a hemoglobin level of ≤8 g per deciliter). The primary outcome was an unfavorable neurologic outcome, defined as a score of 4 or higher on the modified Rankin scale (range, 0 to 6, with higher scores indicating greater disability) at 12 months.

Folate and vitamin B status, through their critical involvement in DNA synthesis and methylation, may be causally related to the risk of schizophrenia. However, associations with blood status measures may reflect reverse causation or inadequate control for confounders. We aimed to synthesize evidence on the possible causal link between folate/vitamin B status and schizophrenia using genetic variants as instrumental variables.

Article Synopsis
  • Muscular strength, particularly measured by handgrip strength (HGS), is an important indicator of health and a predictor of age-related diseases, but no international benchmarks exist for HGS across different ages and sexes.
  • The study systematically analyzed data from over 2.4 million adults across 69 countries to establish sex- and age-specific norms for HGS, identifying a peak in strength between ages 30 and 39 before a gradual decline.
  • Findings revealed that while absolute and body size-normalized HGS improves slightly in early adulthood, a more significant drop occurs from middle to late adulthood, with males generally experiencing a faster decline than females.

Electronic address:

Social media use (SMU) has rapidly increased among children and adolescents in the past decade, and has been linked with poorer mental health. However, moderate SMU can facilitate connectedness among peers, which may have positive impacts for well-being - these associations are underexplored. This study examined the associations between SMU and several indicators of PMH in a nationally representative sample of 13,113 adolescents in grades 6 to 10 from the 2017/2018 cycle of the Canadian Health Behavior in School-aged Children (HBSC) study.

Background: The study aims to explore the burden and trends of prostate cancer (PC) in India at the state level from 1990 to 2021, using data from the Global Burden of Disease (GBD) 2021 study.

Methods: The health metrics including age-standardised incidence rates (ASIR), prevalence rates (ASPR), disability-adjusted life years (ASDR), and mortality rates (ASMR) per 100,000 for PC were analysed across Indian states and union territories. Join point regression analysis was employed to identify significant changes in these metrics over time.

Objectives: Refine the administrative data definition of sepsis in hospitalized patients, including less severe cases.

Design And Setting: For each of 1928 infection and 108 organ dysfunction codes used in Canadian hospital abstracts, experts reached consensus on the likelihood that it could relate to sepsis. We developed a new algorithm, called AlgorithmL, that requires at least one infection and one organ dysfunction code adjudicated as likely or very likely to be related to sepsis.

Article Synopsis
  • The outbreak of Monkeypox (Mpox), especially the clade 1b variant, has become a significant global health issue, particularly in Africa, which is experiencing ongoing epidemics that require urgent attention and study.
  • This research analyzes data from the most affected African countries, using time series techniques to predict Mpox trends and assess the growth in new cases from August 2023 to August 2024.
  • Results indicate a worrying upward trend in Mpox cases, with projections suggesting nearly 6,923 cumulative cases in about 65 weeks, highlighting the need for ongoing monitoring and tailored public health responses to manage the outbreak effectively.

  • * Both male and female schizophrenia patients faced higher risks of all-cause mortality, suicide, and natural causes, but no significant differences were found between the sexes in these risks.
  • * Young females (<40) showed a notably higher mortality risk compared to older females, while males faced a much greater risk of dying from neurological disorders than females, indicating a need for better healthcare interventions.

  • West Nile Virus (WNV) poses a significant global health risk, expanding into new regions due to climate change enhancing mosquito activity, leading to year-round virus transmission.
  • Recent advancements in genomic technologies have improved understanding of WNV's behavior and potential treatment options, yet the lack of an approved vaccine means management relies heavily on supportive care for severe cases.
  • There is a pressing need for innovative vector control methods and adaptive public health strategies that integrate research, policy, and community efforts to effectively combat WNV's evolving challenges.

Open science is a movement that fosters research transparency, reproducibility, and equity. Open science has been put forward by numerous stakeholders in the research ecosystem as a key science policy goal, with the United Nations Educational, Scientific, and Cultural Organization creating recommendations on open science and aligning these with UN Sustainability Goals. Open science practices are not standard to epidemiology despite their potential value to the field and especially during disease outbreaks.

Review of non-invasive biomarkers as a tool for exposure characterization in human health risk assessments.

J Toxicol Environ Health B Crit Rev

February 2025

Risk Sciences International, Ottawa, Canada.

Blood and urine are historically the most frequent matrices used for measuring chemical levels in human biomonitoring studies. As biomonitoring programs are refreshed, consideration of specific priority substances and specific population targets provide opportunities for inclusion of alternative non- or minimally invasive matrices. This review describes methods used in health risk assessment to characterize exposure and risk based upon biomarkers from noninvasive matrices other than urine or blood, including human milk, hair, fingernails, toenails, exhaled breath, deciduous teeth, sweat, semen, meconium, and feces.
