Cardiac valve calcification (CVC), characterized by the accumulation of calcium in the heart valves, is highly prevalent among patients undergoing dialysis. This meta-analysis aimed to provide an updated summary of recent studies on the prognostic value of CVC in patients undergoing dialysis. We conducted a search of PubMed, Embase, and Web of Science to identify observational studies investigating cardiovascular or all-cause mortality associated with CVC in dialysis patients until March 2023.

A fast evolution within mitochondria genome(s) often generates discords between nuclear and mitochondria, which is manifested as cytoplasmic male sterility (CMS) and fertility restoration (Rf) system. The maize CMS-C trait is regulated by the chimeric mitochondrial gene, atp6c, and can be recovered by the restorer gene ZmRf5. Through positional cloning in this study, we identified the nuclear restorer gene, ZmRf5, which encodes a P-type pentatricopeptide repeat (PPR) family protein.

Narrowing down to a single putative target gene behind a leaf senescence mutant and constructing the regulation network by proteomic method. Leaf senescence mutant is an important resource for exploring molecular mechanism of aging. To dig for potential modulation networks during maize leaf aging process, we delimited the gene responsible for a premature leaf senescence mutant els5 to a 1.

Although recent medical studies have found a significant correlation between betel quid chewing and oral cancer, some Taiwanese aboriginal people continue the traditional betel quid culture. Using the transtheoretical model framework, we conducted a qualitative study to examine the stages of behavioral change in betel quid chewing in the Paiwan sociocultural context. We conducted in-depth interviews with 20 aboriginal chewers of betel quid.

The aim of this study was to explore how hemodialysis patients' quality of life is related to sociodemographic data and depression as predicting variables, and how it is affected by fatigue as a mediating variable. Participants were 405 patients who has been receiving hemodialysis treatment regularly. SPSS Amos path analysis was used to explore the causal relationship and the mediating effect of fatigue among the variables of sociodemographic characteristics, depression, and quality of life.

Numerous epidemiological studies have shown that male patients with uric acid nephrolithiasis outnumber female patients. To our knowledge, no research exists evaluating the reasons gender affects the development of uric acid nephrolithiasis. We hereby used a novel application of structural equation modeling to analyze the mediators of the effects of gender on uric acid nephrolithiasis.

Background: The impact of pay-for-performance (P4P) programs on long-term mortality for chronic illnesses, especially diabetes mellitus, has been rarely reported. Several studies described the favorable impact of P4P for diabetes mellitus on medical utilizations or intermediate outcomes. Therefore, this study aimed to investigate the impact of a P4P program on mortality in patients with type 2 diabetes.

Background: There are few published studies addressing multiple substance uses and their effects on subsequent cessation of betel quid (BQ) chewing in the Asia Pacific region.

Objectives: This study aims to investigate the usage patterns of BQ chewing, cigarette smoking, and alcohol drinking, and their correlates with subsequent BQ cessation among a male inmate population.

Methods: Data from 473 male inmates with a history of BQ use who were incarcerated in Taiwan Kaohsiung Prison was used for this analysis.
