To find support for risk-modifying genes in breast cancer, a haplotype GWAS in sporadic breast cancer cases was undertaken. The results were compared with the results from previous analyses in familial cases and all cases from the same Swedish cohort. In total, 2550 women with sporadic invasive breast cancer and 5021 healthy controls were included in a sliding-window haplotype GWAS using PLINK 1.

Introduction: Understanding the health risks associated with extreme weather events is needed to inform policies to protect vulnerable populations. To address this need, we estimated heat and cold wave related mortality risks in a cohort of veteran patients with chronic obstructive pulmonary disease (COPD) and explored disparities among strata of comorbidities, tobacco exposure, and urbanicity.

Methods: We designed a time stratified case-crossover study among deceased patients with COPD between 2016 to 2021 in the Veterans Health Administration system.

  • Severe asthma can be exacerbated by specific environmental conditions, particularly during thunderstorms with high pollen, known as 'thunderstorm asthma.'
  • A study in Minneapolis-St. Paul analyzed emergency department visits for asthma during these events, revealing that while overall risk increased by 6%, children under 18 showed no heightened risk compared to adults ages 18-44 and those 45 and older, who had a higher relative risk of asthma-related visits.
  • The findings emphasize the need for more awareness and tailored clinical treatments based on varying susceptibility to thunderstorm asthma across different age and sex groups, highlighting it as an important environmental health issue.

Article Synopsis
  • Studies show that different subgroups (based on sex, race, etc.) experience varying disease courses and outcomes, and current analysis methods fail to consider this diversity.* -
  • The authors propose a new statistical approach called Heterogeneity in Integration and Prediction (HIP) that combines multiple data types while factoring in subgroup differences to identify shared and unique molecular signatures.* -
  • HIP has been applied to investigate COPD, revealing important proteins and genes linked to sex differences in the disease, and offers tools for broader research applications in health disparities.*

Introduction: Since 2007, the classification of ethanol under the Biocidal Products Regulation has paradoxically remained unresolved due to conflicting views among experts and authorities. Initially, there was a discussion about classifying ethanol as carcinogenic. The current proposal to extend its harmonized classification includes, among other things, categorizing it as reproductive toxicity category 2 ("suspected to have CMR potential for humans"; carcinogenic, mutagenic, reprotoxic).

Individuals living in rural areas in the United States experienced disparities in COVID-19 incidence and mortality rates, and people with chronic obstructive pulmonary disease (COPD) are at high risk of poor outcomes. We sought to determine whether veterans with COPD living in rural areas experienced different perceptions and practices of COVID-19 mitigation strategies, access to care, and health disparities during the COVID-19 pandemic, compared to their urban-living counterparts. We performed a one-time survey of veterans with COPD, collecting COVID-19-related information including individual perceptions and practice of mitigation strategies, COVID-19 vaccination status, access to care, and respiratory symptoms stratified by rural-urban status.

The extent of loneliness differs internationally. Especially in the developed welfare states of Northern Europe, loneliness levels in the population are comparatively low. However, the increase in loneliness in many countries shows that existing concepts are not sufficient to provide effective protection against loneliness.

This study investigated whether chronic undernutrition alters the mitochondrial structure and function in renal proximal tubule cells, thus impairing fluid transport and homeostasis. We previously showed that chronic undernutrition downregulates the renal proximal tubules (Na+K)ATPase, the main molecular machine responsible for fluid transport and ATP consumption. Male rats received a multifactorial deficient diet, the so-called Regional Basic Diet (RBD), mimicking those used in impoverished regions worldwide, from weaning to a juvenile age (3 months).

Article Synopsis
  • * Analysis of data from over 55,000 breast cancer patients showed that co-observation of variants in BRCA1, BRCA2, and PALB2 with other breast cancer genes occurred less frequently than expected, suggesting a potential correlation with pathogenicity.
  • * The findings indicate that identifying a variant of uncertain significance alongside a known pathogenic variant supports evidence against the variant's pathogenicity, which could improve variant classification in clinical settings and for other genetic conditions.

Integrative factorization methods for multi-omic data estimate factors explaining biological variation. Factors can be treated as covariates to predict an outcome and the factorization can be used to impute missing values. However, no available methods provide a comprehensive framework for statistical inference and uncertainty quantification for these tasks.

Airway microbiota are known to contribute to lung diseases, such as cystic fibrosis (CF), but their contributions to pathogenesis are still unclear. To improve our understanding of host-microbe interactions, we have developed an integrated analytical and bioinformatic mass spectrometry (MS)-based metaproteomics workflow to analyze clinical bronchoalveolar lavage (BAL) samples from people with airway disease. Proteins from BAL cellular pellets were processed and pooled together in groups categorized by disease status (CF vs.
