Summary: This study identifies critical exposure windows of maternal air pollution exposures associated with low birth weight (LBW) in offspring using a novel method. Through a case-control study based on birth data and air quality monitoring data in Texas, the study identifies ten chemicals and seventeen critical exposure windows where strong air pollutant-LBW associations are detected. The novel method reveals a number of critical time windows of maternal exposure to these chemicals that are positively associated with LBW in offspring.

Summary: The study found associations between heat, PM2.5 exposure, and lower term birth weight, with pregnant women being more susceptible to these exposures towards the end of pregnancy. Heat sensitivity was higher in the initial weeks of pregnancy as well. These findings suggest critical windows of susceptibility that could be communicated to pregnant women during routine prenatal visits to increase awareness and target interventions to reduce exposures.

Summary: Using the method of analyzing mixed exposures, this study found that the combined exposure of air pollutants and pregnancy-related anxiety (PrA), particularly during the first trimester, is associated with a decrease in birth weight for gestational age z-score (BWz). This supports the view that prenatal exposure to chemical and non-chemical stressors has an impact on fetal growth.

Summary: This study explores the association between maternal exposure to ambient air pollutants and the risk of very low birth weight (VLBW), and identifies the sensitive exposure time window. The results suggest that high levels of PM2.5, PM10, NO2, and O3 during pregnancy may increase the risk of VLBW, especially during the first and second trimester. Therefore, reducing the risk of early maternal exposure to ambient air pollution is necessary.

Summary: This article focuses on establishing reference case methods for expert elicitation to inform health care decision making. Methods choices for elicitation lack empirical evidence supporting recommendations, but reference case methods have been determined for health technology assessment. The reference methods prioritize experts with substantive knowledge, eliciting quantities directly observed by experts, and individual elicitation of beliefs. Further applied examples and experimental evidence comparing methods are recommended.

Summary: Time-to-event data can be right-truncated, leading to biased distribution towards shorter times in the sample compared to the population. This article reviews statistical methods to address this bias, particularly in the context of infectious disease epidemics like COVID-19. Issues of identifiability, estimation of time-to-event distribution, and the effects of covariates are discussed, with an illustration using data on individuals who died with coronavirus disease by April 5, 2020.

Summary: This study investigates the risks of hospital admission, death without hospital admission, and recovery without admission for people with symptomatic COVID-19 in Milan, Italy. The results show that the risk of death without hospital admission was higher during the severe burden on the healthcare system, especially for care home residents. The outcomes improved as the first wave of the pandemic waned, community healthcare resources were reinforced, and testing became more widely available.

Summary: This study investigated the potential mediating factors, including lung function, pulmonary exacerbations, and nutritional status, through which cystic fibrosis-related diabetes (CFRD) affects the composite outcome of mortality or transplant in adult cystic fibrosis (CF) patients. The results showed that pulmonary exacerbations were the strongest mediator of the effect, attributing to a significant proportion of the total effect. Other factors may also contribute to the influence of CFRD on patient survival.

Summary: This study reveals time-varying differences in the hazard of all-cause mortality after liver transplantation between hepatocellular carcinoma (HCC) recipients and non-HCC recipients. It also provides evidence that some HCC patients have extra-hepatic spread at the time of transplantation, which has implications for post-transplant surveillance protocols.

Summary: This study analyzed the impact of modern glucose-monitoring strategies on glycemic and patient-related outcomes in individuals with type 2 diabetes (T2D) and recent myocardial infarction (MI). The results showed that compared with self-monitoring of blood glucose (SMBG), intermittently scanned continuous glucose monitoring (isCGM) marginally increased time in range and significantly reduced hypoglycemic exposure in T2D individuals with MI, while equally improving HbA(1c). These findings explain the cost effectiveness of isCGM.

Summary: Multimorbidity, characterized by the coexistence of multiple chronic conditions, is a rising public health concern. This study utilized electronic primary care records from England to examine the associations between sociodemographic characteristics and the rate of disease progression. The findings indicate strong associations between social deprivation, gender, and age with disease diagnosis, which tend to attenuate with an increase in the number of preexisting conditions.
