Summary: The obesity paradox refers to the phenomenon where obese individuals have better life expectancy or fewer cardiovascular events in certain diseases. Collider bias is a plausible explanation, but its controversy remains. The use of appropriate analytical techniques is crucial in unraveling the nature of the obesity bias.

Summary: The obesity paradox refers to the observation that certain chronic diseases show a protective association between body mass index (BMI) and clinical outcomes. However, this association may be influenced by factors such as limitations of BMI, unintended weight loss due to chronic illness, different phenotypes of obesity, and cardiorespiratory fitness levels. Recent evidence suggests that cardioprotective medications, obesity duration, and smoking status also play a role in the obesity paradox.

Summary: There is a paradoxical relationship between obesity and cardiovascular disease where obese individuals may have a more favorable prognosis in certain cardiovascular conditions. Factors such as cardiorespiratory fitness, increased lean mass, and adipose tissue acting as a metabolic reserve may help explain this phenomenon.

Summary: Evidence suggests a strong link between maternal obesity and poorer cardiovascular health in offspring throughout life, from infancy into adulthood. While underlying mechanisms remain unclear, targeted maternal obesity prevention measures are supported to promote cardiovascular health in offspring.

Summary: In this meta-analysis, an inverse association between circulating AGEs and body mass index among adults was observed, while the association between dietary AGEs and body mass index was inconclusive. Individuals with obesity had lower levels of circulating AGEs compared to those without obesity. The type of AGEs may contribute to the heterogeneity observed.

Summary: This article explores the issue of Simpson's paradox in offline evaluation of recommendation systems and proposes a novel evaluation methodology based on stratified sampling to address the confounding factor. The proposed evaluation methodology shows significant improvements compared to the standard evaluation in reflecting the true ranking of systems with an open loop evaluation.

Summary: This study aims to determine the role of physical fitness in the obesity paradox in women with ischaemic heart disease (IHD). The findings suggest that physical fitness plays a role in the association between obesity and cardiovascular outcomes in women. Overweight and obese women with good physical fitness had lower long-term all-cause mortality, while normal weight women with poor physical fitness had higher risk of major adverse cardiovascular events (MACE).

Summary: Obesity has become a serious public health problem and brings a heavy burden of cardiovascular disease. Whether individuals with metabolically healthy obesity (MHO) have a lower cardiovascular risk remains controversial. This study aimed to define MHO using a new criterion and assess its predictive value for cardiovascular events and death, while comparing it with the traditional criterion.

Summary: This study demonstrated that patients with biopsy-proven NAFLD have a significantly higher risk of major adverse cardiovascular events, including ischemic heart disease, stroke, congestive heart failure, and cardiovascular mortality, compared to matched population controls. The risk of such events increases progressively with worsening NAFLD severity.

Summary: Obesity paradox exists in acute coronary syndrome (ACS) patients, where obese patients have better clinical outcomes compared to underweight and normal weight patients. Over a 2-decade period, the rates of major cardiovascular events (MACE) and mortality have decreased among overweight and obese ACS patients, while remaining consistently high in underweight patients.

Summary: This study found that among Taiwanese adults, the ADH1B rs1229984 TC + CC genotype and alcohol consumption of at least 150 ml/week may increase the risk of developing hemorrhagic stroke. The ALDH2 rs671 genotype was not associated with hemorrhagic or ischemic stroke among alcohol drinkers.

Summary: Globally, the point prevalence and death rates of other musculoskeletal disorders increased in 2017, with higher estimates among females and increasing prevalence with age. The data suggests a need for specific disease information within this category for future global burden of disease estimates to inform resource allocation and interventions.

Summary: Medicine has evolved from a mystical healing art to a mature science of human health through a rigorous process of quantification, experimentation, and evaluation. Folkloric traditions, such as race- and ethnic-specific medicine will fade from use as we become increasingly critical of outdated and irrational clinical practices and replace these with personalized, evidenced-based tests, algorithms, and procedures that privilege patients' individual humanity over obsolete and misleading labels.

Summary: This study provides a comprehensive report on the levels and trends of 13 cancers attributable to excess body weight (EBW) from 1990 to 2019 in 204 countries and territories. The findings suggest that the burden of EBW-attributable cancers has been increasing globally over the past three decades. There are significant variations between countries and regions, highlighting the need for tailored preventive interventions.

Summary: The study investigated the association between changes in long-term residential exposure to ambient fine particulate matter (PM2.5) and premature mortality in Canada. The results showed that decreases in PM2.5 were associated with lower mortality, while increases in PM2.5 were associated with higher mortality, particularly in relation to deaths from cardiometabolic causes. Overall, the findings support the continuous improvement of air quality.

Summary: Alcohol consumption is associated with various cancers, and it places a higher burden on males, the elderly, and developed regions. Despite recent decreases, significant numbers of cancer deaths and DALYs are still attributable to alcohol consumption.

Summary: This study found that ambient PM2.5 concentrations in Canada decreased from 2001 to 2016, but disadvantaged communities with lower income, education, and higher proportions of aboriginal population did not benefit equally. This highlights the need to address environmental injustice in air pollution policies.

Summary: Reducing anthropogenic contributions to PM2.5 could lead to significant health benefits, even in a country like Canada where PM2.5 levels are already low. A 10% annual reduction in PM2.5 contributions from transportation and power generation sources could prevent a substantial number of deaths per million by 2016.

Summary: This study investigates the mediation effect of diabetes and cardiovascular diseases on the relationship between long-term exposure to PM2.5 and mortality. The results suggest that a significant portion of the effect of PM2.5 on deaths can be attributed to its impact on diabetes and cardiovascular diseases, emphasizing the importance of PM2.5 on cardiovascular health deterioration.

Summary: This article provides an overview of regression-based causal mediation analysis in the field of traumatic stress and offers guidance on conducting mediation analysis using the R package regmedint. The authors discuss the causal interpretations of the estimated quantities in causal mediation analysis, including total, direct, and indirect effects, especially when there is an interaction between exposure and mediator. They also discuss the necessary assumptions and suitable study designs for valid estimation of these causal quantities, as well as the differences between causal mediation analysis and traditional methods of mediation. By using data from a published longitudinal study, the authors illustrate how to conduct and interpret mediation analysis using regmedint and compare the results to those obtained using traditional methods, highlighting the importance of accounting for exposure-mediator interaction.

Summary: The COVID-19 pandemic has had a significant impact on cancer mortality rates and place of death in Brazil, Chile, and Peru. The implementation of lockdown measures resulted in a decrease in overall cancer mortality rates and an increase in at-home deaths, with a corresponding decrease in hospital deaths observed only in Chile.

Summary: The increasing caregiving needs for family members are creating pressure on prime-age workers. This, combined with the ageing population, means more of the workforce may need to consider caring needs. Informal caregivers provide care without payment and usually have a close relationship with the recipient, making them a preferred option in meeting support needs.
