Using Mendelian randomization and observational analyses, Qian Yang and colleagues investigate the associations between insomnia and stillbirth, miscarriage, gestational diabetes, hypertensive disorders of pregnancy, perinatal depression, preterm birth, and low and high birth weight.
L-carnitine is emerging as an item of interest for cardiovascular disease (CVD) prevention and treatment, but controversy exists. To examine the effectiveness and safety of l-carnitine, we assessed how genetically different levels of l-carnitine are associated with CVD risk and its risk factors. Given higher CVD incidence and l-carnitine in men, we also examined sex-specific associations. We used Mendelian randomization to obtain unconfounded estimates. Specifically, we used genetic variants to predict l-carnitine, and obtained their associations with coronary artery disease (CAD), ischemic st...
To quantitatively assess the impact of the onset-to-diagnosis interval (ODI) on severity and death for coronavirus disease 2019 (COVID-19) patients. This retrospective study was conducted based on the data on COVID-19 cases of China over the age of 40 years reported through China’s National Notifiable Infectious Disease Surveillance System from February 5, 2020 to October 8, 2020. The impacts of ODI on severe rate (SR) and case fatality rate (CFR) were evaluated at individual and population levels, which was further disaggregated by sex, age and geographic origin. As the rapid d...
Tuberculosis (TB) poses a severe public health challenge in China and worldwide. This study evaluated the effects of age, period, and birth cohort on reported incidence trends of TB based on population and refined the characteristics of high-risk groups. Aggregate data that reported pulmonary tuberculosis (PTB) cases from China Tuberculosis Management Information System (TBIMS) from 2006 to 2020 were used to analyze effect coefficients through the age–period–cohort (APC) model based on intrinsic estimator (IE) method, and converted them into relative risk (RR) to estimate trends. A...
Xinge Zhang and colleagues estimate remaining lifetime risk of diabetes and life years spent with diabetes in Chinese people with normoglycaemia and prediabetes.
