A major goal of healthy aging is to prevent declining resilience and increasing frailty, which are associated with many chronic diseases and deterioration of stress response. Here, we propose a loss-or-gain survival model, represented by the ratio of cumulative stress span to life span, to quantify stress resilience at organismal level. As a proof of concept, this is demonstrated by reduced survival resilience in Caenorhabditis elegans exposed to exogenous oxidative stress induced by paraquat or with endogenous proteotoxic stress caused by polyglutamine or amyloid-β aggregation.

Background: Management of comorbidities of people living with HIV (PLHIV) involves different care models, including providing diabetes care and HIV care by the same infectious diseases physician (IDP) ("consolidated care") or providing diabetes care by the physicians other than IDP ("shared care"). The impact of diabetes care model on PLHIV with diabetes mellitus (DM) has not been well-evaluated.
Methods: A nationwide cross-sectional sample in the Taiwan National Health Insurance Research Database was used to compare the performance rates of seven guideline-recommended tests provided by the different subspecialists.
Objective: This study explored the rejuvenation mechanisms of Thai polyherbal medicines using different approaches, including in vitro methods, as well as a well-defined nematode model, Caenorhabditis elegans.
Methods: THP-R-SR012 decoction was selected from 23 polyherbal medicines, based on metal-chelating and chain-breaking antioxidant capacities. The influences of this extract on the survival and some stress biomarkers of C.
Background: Most studies on the physician code creep (i.e., changes in case mix record-keeping practices to improve reimbursement) have focused on episodes (inpatient hospitalizations or outpatient procedures).

Methods: Drowning mortality data of 61 countries were extracted from the World Health Organization Mortality Database. We calculated the percentage change (PC) in age-standardized drowning mortality rates and percentage of drowning deaths reported with unspecified codes between 2004 and 2005 and 2014-2015.
Background: Several studies have hypothesized that the pattern of health care utilization among maltreated children differ from others without the experience. However, the conclusions have not been consistent.
Objective: The study aims to examine whether the pattern of health care utilization among children 0-5 years old with maltreatment different from their counterparts without maltreatment in Taiwan.
Objective: To examine changes in the number and causes of maternal deaths after the introduction of pregnancy checkbox on the death certificate in January 2014 in Taiwan.
Materials And Methods: We first used the cause-of-death (COD) mortality data for years 2010 through 2017 to examine the number of deaths by item of pregnancy checkbox. We then compared the distribution of the causes of maternal deaths before and after the introduction of pregnancy checkbox.
Objective: To investigate regional variation in the registration of births (still+live) as live born for birth weight <500 g and the impact on the city/county ranking of neonatal mortality rate (NMR) in Taiwan.
Design: Population-based cross-sectional ecological study.
Setting: 20 cities/counties in Taiwan.
The moderator effect of retention in care on late presenters in HIV patients has not been well evaluated. A nationwide cohort study focusing on HIV-infected patients with new engagement in care was conducted by using the Taiwan National Health Insurance Research Database. Retention in care was defined based on the healthcare utilization in the first year after engaging in HIV care.

Paeoniflorin has been previously shown to attenuate cognitive damage inflicted by exogenous Aβ protein. Using transgenic Caenorhabditis elegans models expressing human Aβ, we demonstrate here that paeoniflorin can delay progressive paralysis caused by endogenous Aβ expression and reduce the amount of toxic Aβ oligomers in vivo, although it has no effect on Aβ aggregation in vitro.

The outcomes of implantation, clinical pregnancy, multiple pregnancy and miscarriage, between groups with and without sHLA-G in embryo culture media, were analysed. Fifteen studies with a total of 6170 cases were included.

Design: This study had a case-control design nested within a cohort of 1 million people from the general population, which was followed from 2005 to 2010. The odds of prior clinical visits for DHSs, namely carpal tunnel syndrome (CTS), flexor tenosynovitis, limited joint mobility and Dupuytren's disease, were estimated for cases and controls.
Background: Population-based data for diabetic hand syndrome (DHS) are limited. The aim of the present epidemiological study was to estimate the overall and cause-specific prevalence and rate ratio (RR) of DHS in patients with diabetes.
Methods: The present study was a cross-sectional study based on a random sample of 57 093 diabetics and matched controls, both identified from Taiwan National Health Insurance claims in 2010.
The aim of this study was to assess the overall and cause-specific incidences of diabetic hand syndromes (DHS) in patients with diabetes mellitus (DM) by using age and sex stratifications.The DM and control cohorts comprised 606,152 patients with DM and 609,970 age- and sex-matched subjects, respectively, who were followed up from 2000 to 2008. We estimated the incidence densities (IDs) of overall and cause-specific DHS, namely carpal tunnel syndrome (CTS), stenosing flexor tenosynovitis (SFT), limited joint mobility (LJM), and Dupuytren disease (DD), and calculated the hazard ratios (HRs) of DHS in relation to DM by using a Cox proportional hazards model with adjustment for potential confounders.

The aim of this study was to use cluster analysis to define COPD phenotypes and validate them by assessing their relationship with mortality.
Methods: Male subjects with COPD were recruited to identify and validate COPD phenotypes.
The case-control study is a simple and an useful method to characterize the effect of a gene, the effect of an exposure, as well as the interaction between the two. The control-free case-only study is yet an even simpler design, if interest is centered on gene-environment interaction only. It requires the sometimes plausible assumption that the gene under study is independent of exposures among the non-diseased in the study populations.

Objective: Genetic studies of complex human diseases rely heavily on the epidemiologic association paradigm, particularly the population-based case-control designs. This study aims to compare the matching effectiveness in terms of bias reduction between exposure matching and stratum matching.
Study Design And Setting: Formulas for population stratification bias were derived.
The case-only study is a convenient approach and provides increased statistical efficiency in detecting gene-environment interactions. The validity of a case-only study hinges on one well-recognized assumption: The susceptibility genotypes and the environmental exposures of interest are independent in the population. Otherwise, the study will be biased.

In all dogs, anesthesia was induced with an intravenous injection of propofol following premedication with acepromazine or diazepam. As a result, 58 dogs anesthetized with propofol-TIVA showed slower but smoother recovery than 91 dogs anesthetized with isoflurane anesthesia.

The case-control study design is popular for genetic association studies of complex human diseases. However, case-control studies may suffer from bias due to population stratification. In this paper, the authors present simple formulas that can set a limit to the havoc population stratification bias can wreak (the lower and upper bounds of the confounding rate ratio and the upper bound of the type I error rate).
