Objective: This study aimed to validate the effects of a simplified, gentle form of t'ai chi chuan in patients with type 2 diabetes and who are also obese. Design: The study was designed to be a randomized controlled trial. Setting: This study was conducted in the department of metabolism and endocrinology at Cheng Ching Hospital, in Taichung, Taiwan. Subjects: The study subjects were hospital-based patients with type 2 diabetes and who were also obese (ages 40–70, with a body–mass index [BMI] range of 30–35). The patients were randomly selected and grouped into t'ai chi exercise (TCE) and conventional exercise (CE) groups. Interventions: After receiving instruction in t'ai chi, the TCE group and the CE group practiced three times per week, including one practice session lasting up to 1 hour, for 12 weeks. Outcome measures: Hemoglobin A1C, serum lipid profile, serum malondialdehyde, and C-reactive protein were measured. Physical parameters of body weight and BMI were also measured. Diet and medications of participants were monitored carefully while biochemical and physical conditions were analyzed. Results: After 12 weeks, hemoglobin A1C values of the TCE group did not decrease (8.9 ± 2.7% : 8.3 ± 2.2%; p = 0.064). BMI (33.5 ± 4.8 : 31.3 ± 4.2; p = 0.038) and serum lipids, including triglyceride (214 ± 47 mg/dL : 171 ± 34 mg/dL; p = 0.012) and high density lipoprotein cholesterol (38 ± 16 mg/dL : 45 ± 18 mg/dL; p = 0.023) had significant improvements. Serum malondialdehyde tended to decrease from baseline (2.66 ± 0.78 μmol/L : 2.31 ± 0.55 μmol/L; p = 0.035), and C-reactive protein also decreased (0.39 ± 0.19 mg/dL : 0.22 ± 0.15 mg/dL; p = 0.014). No improvements occurred in BMI, lipids, and oxidative stress profiles in the CE group. Conclusions: T'ai chi exercise practiced by patients who are obese and have type 2 diabetes is efficient and safe when supervised by professionals and helps improve parameters, such as BMI, lipid profile, C-reactive protein, and malondialdehyde. Periodic monitoring of blood glucose, blood pressure, heart rate, breathing, physical fitness, and symptoms of discomfort of patients who exercise helps prevent injury. Simple, gentle TCE can be applied as regular daily exercise for patients with type 2 diabetes even when such patients are obese.

Objectives Self-rated health (SRH) is an assessment and predictor of health based on an individual’s general condition; however, evidence of the value of SRH for predicting frailty remains scarce for older Asian adults. This study aimed to evaluate the relationship between SRH score trajectory and frailty among older individuals in Taiwan. Design An 8-year retrospective cohort study. Setting Data were retrieved from the Taiwan Longitudinal Study on Aging from 1999 to 2007. Participants Respondents aged 53–69 years old who were not frail or disabled in 1999 (n=1956). Primary and secondary outcome measures Frailty was defined using the Fried criteria. The group-based trajectory modelling technique was used to estimate SRH trajectories. Logistic regression analysis was used to examine the associations between changes in SRH and frailty. Results Four SRH trajectory classes were identified across the 8-year follow-up: 232 participants (11.9%) were classified into the constantly poor SRH group, 1123 (57.4%) into the constantly fair SRH group, 335 (17.1%) into the constantly good SRH group and 266 (13.6%) into the good-to-fair SRH group. After adjusting for gender, age, level of education, income, social participation, health behaviours and major comorbidities, it was found that age, poor income satisfaction, without job and constantly poor SRH were associated with increased risk of frailty, while constantly good SRH (OR 0.04, 95% CI (0.01 to 0.32)) and good-to-fair SRH (OR 0.19, 95% CI (0.06 to 0.63)) were associated with reduced risks of frailty. Conclusions Constantly poor SRH was associated with an increased risk of frailty in older age. SRH in older adults should be recognised as a predictive tool for future frailty. Diet and exercise interventions may help to prevent frailty among high-risk older individuals with constantly low SRH.

From June to September 2011, a total of 305 ertapenem-nonsusceptible Enterobacteriaceae isolates (MICs of ertapenem ≥ 1 μg/ml) were collected from 11 hospitals in different parts of Taiwan. The MICs of 12 antimicrobial agents against these isolates were determined using the broth microdilution method, and genes for carbapenemases were detected using PCR. Genotypes of isolates possessing carbapenemase genes were identified by pulsed-field gel electrophoresis (PFGE) and multilocus sequence typing. The ertapenem-nonsusceptible Enterobacteriaceae isolates included Klebsiella pneumoniae ( n = 219), Escherichia coli ( n = 64), Enterobacter cloacae ( n = 15), and other species ( n = 7). Seven (2.3%) of the ertapenem-nonsusceptible Enterobacteriaceae isolates exhibited colistin MICs of >4 μg/ml, and 24 (7.9%) were not susceptible to tigecycline (MICs > 2 μg/ml). A total of 29 (9.5%) isolates carried genes encoding carbapenemases, namely, K. pneumoniae carbapenemase-2 (KPC-2) in 16 (7.3%) isolates of K. pneumoniae (KPC-2-KP) and IMP-8 in 5 (2.3%) isolates of K. pneumoniae , 5 (33.3%) isolates of E. cloacae , 1 isolate of E. coli , 1 isolate of Klebsiella oxytoca , and one isolate of Citrobacter freundii . The 16 KPC-2-KP isolates were isolated from patients at four different hospitals in northern Taiwan. All 16 of the KPC-2-KP isolates were susceptible to amikacin and colistin and had a similar pulsotype (pulsotype 1) and the same sequence type (sequence type 11). Infections due to KPC-2-KP mainly occurred in severely ill patients in the intensive care unit ( n = 14, 88%). Four patients with infections due to KPC-2-KP died within 14 days of hospitalization. The findings are the first to demonstrate intrahospital and interhospital dissemination of KPC-2-KP in northern Taiwan.

In addition to increasing the mortality among older adults, spousal death (SD) increases their risk of depression. This study explored the factors affecting depression among widowed older adults to provide health care strategies for successful aging. A total of 710 adults older than 60 years completed a questionnaire before and after their spouses’ deaths. The survey data included age, sex, ethnic group, education level, financial station socioeconomic status, SD (including time point), smoking status, alcohol consumption, self-rated health status, Center for Epidemiologic Studies Depression Scale score, mobility, and degree of support from relatives and friends. The proportion of participants with depression after SD was 1.7 times that of before SD (p < 0.0001). Worsened mobility (odds ratio [OR] = 1.3, p < 0.01), low self-rated health status (OR = 0.5, p < 0.01), and a high degree of support from relatives and friends (OR = 1.5, p < 0.01) had a significant positive correlation with depression after SD. The proportion of depression that occurred within 6 months after SD was 6.0 times higher than that of depression before SD. Participants who lived alone after losing their spouses who were healthy before their deaths exhibited a significantly increased proportion of depression after their spouses’ deaths. Male sex, spouse’s health, and the period of 6 months after SD are risk factors for depression in older adults. The maintenance of mobility, positive self-rated health status, and a shorter period of depression after a spouse’s death result in more favorable adaptability among women. Social workers or family members should focus on older adults whose spouses died unexpectedly or within the last 6 months. Living with family members after SD can alleviate depression in older adults.
