Study Question: What is the prevalence and trend of infertility among individuals of childbearing age at global, regional, and national levels by sex and socio-demographic index (SDI) across 21 regions and 204 countries and territories?
Summary Answer: Our findings reveal a growing prevalence of infertility among individuals aged 15-49 years worldwide from 1990 to 2021, with an expected continued increase through 2040.
What Is Known Already: Infertility is a persistent global reproductive health issue, leading to significant societal and health consequences. No study has specifically described the current prevalence of infertility, its secular trend, or the variations between regions or countries with different SDI levels.
Background: The fat mass and obesity-associated protein (FTO) has been showed to be involved in the pathogenesis and progression of coronary artery disease (CAD). However, the effects of FTO variants on CAD risk remain poorly understood. We herein genotyped three SNPs (rs1121980, rs72803657, and rs4783818) in FTO to investigate the influence of FTO polymorphisms on individual susceptibility to CAD.

However, the underlying mechanisms of these functions remain elusive. Here, utilizing a metabolic clustered regularly interspaced short palindromic repeats (CRISPR)-Cas9 knockout library screen, we observe that the loss of glutamate-cysteine ligase modifier subunit (GCLM), a rate-limiting enzyme in glutathione biosynthesis, noticeably increases the sensitivity of colorectal cancer (CRC) cells to platinum-based chemotherapy.

The aim of this study was to assess the relationship between nutritional risk on admission and in-hospital mortality, and explore the best Nutritional Risk Status Screening 2002 (NRS2002) threshold for predicting in-hospital mortality of older inpatients in China.
Method: The elderly inpatients were recruited from a hospital in Hunan Province, China.
