Prognostic Factors for Mortality, Activity of Daily Living, and Quality of Life in Taiwanese Older Patients within 1 Year Following Hip Fracture Surgery.

BACKGROUND: Hip fractures among older adults are a major public health concern worldwide. This study investigated the potential clinical factors that predict postoperative 1-year activities of daily living (ADL), quality of life (QoL), and mortality in Taiwanese older adults following hip fracture. METHODS: This is a prospective cohort study enrolling older adults (≥60 years) who had undergone hip fracture surgery in a single medical center. The comprehensive clinical history of each patient was examined. QoL, ADL, and mortality events were recorded consecutively at 3, 6, and 12 months after operation. The multiple logistic regression model and the generalized estimating equation (GEE) were adopted to identify contributing factors for mortality and postoperative ADL and QoL prognosis, respectively. RESULTS: Among 377 participants with hip fracture, 48 died within 1 year of the index operation. ADL and QoL considerably decreased at 3 months following hip surgery. Old age, high Charlson Comorbidity Index, and American Society of Anesthesiologists grading were crucial predictors for mortality at the 1-year follow-up. The generalized estimating equation analysis indicated that the length of postoperative follow-up time, serum albumin level, patient cognitive status, and handgrip strength were considerably associated with QoL and ADL recovery prognosis in the Taiwanese older adults following hip fracture. CONCLUSIONS: Hip fractures have long-lasting effects on the older adults. Our data imply several prognosis predicting parameters that may assist clinicians in accounting for an individual's personalized risks in order to improve functional outcomes and reduce mortality.

The association between weight gain at different stages of pregnancy and risk of gestational diabetes mellitus.

AIMS/INTRODUCTION: Women with excessive gestational weight gain (GWG) are at a higher risk for complications during pregnancy, such as preeclampsia. However, the association between excessive GWG and gestational diabetes mellitus (GDM) remains unclear. MATERIALS AND METHODS: We retrospectively reviewed 8,352 women from our obstetric database with singleton pregnancies who gave birth after 28 completed weeks of gestation between January 1, 2012, and December 31, 2016, excluding pregnancies complicated by fetal anomalies, fetal death, and overt diabetes. Diagnosis of GDM was based on the criteria recommended by the International Association of Diabetes and Pregnancy Study Groups. We used two classification methods to define excessive GWG: a weight gain above the 90th percentile of the population, or exceeding the upper range recommended by the Institute of Medicine, stratified by pre-pregnancy body mass index. Statistical analysis was performed using multiple logistic regression to determine the association between excessive GWG and the risk of GDM. RESULTS: Overall, 1,129 women (13.5%) were diagnosed with GDM. There was no difference in GWG between women with and without GDM in the first trimester and before GDM screening. Women with GDM had significantly less GWG in the second trimester, after GDM screening, and throughout the whole gestation than women without GDM. No correlation was found between excessive GWG in the first and second trimesters, before GDM screening, and the later development of GDM. CONCLUSIONS: Our results indicate that excessive GWG prior to GDM screening is not associated with an increased risk of GDM.

Lowered obesity indicator cutoff points more effectively predict 5-year incidence of hypertension in premenopausal women.

OBJECTIVE: To compare proposed new cutoff points for four obesity indicators-waist-to-height ratio (WHtR), waist circumference (WC), waist-to-hip ratio (WHR) and body mass index (BMI)-with their current cutoff points to determine which are better standards predicting 5-year incidence of hypertension (HT) and diabetes mellitus (DM) among premenopausal women. DESIGN: Data were obtained from the 2002 and 2007 Survey on the Prevalence of HT, Hyperglycemia and Hyperlipidemia in Taiwan conducted by the Ministry of Health and Welfare, Taiwan. Premenopausal women were grouped based on the proposed cutoff points versus reference cutoff points for obesity indicators. PARTICIPANT: A total of 1466 premenopausal women aged between 20 and 57 years old were recruited. MAIN OUTCOME MEASURE: Five-year incidence of HT and DM. RESULTS: Our new obesity indicator cutoff points-WHtR 0.49, WC 74.7 cm, WHR 0.79 and BMI 22.3 kg/m2-were better predictors for 5-year HT incidence in premenopausal women compared with those of current standards, but were not significantly different for DM. Among the four obesity indicators, WHtR and WC were optimal for their 5-year predictive ability for HT and DM in premenopausal women. CONCLUSIONS: To avoid too many cutoff points for practitioners to adopt and memorize, the proposed new cutoff points were recommended preferentially to prevent the incidence of HT and DM in premenopausal women.

Risk factors for gestational diabetes mellitus among women screened with the two-step and one-step methods: A before-and-after study.

OBJECTIVE: To compare the risk profiles for gestational diabetes mellitus (GDM) using a one-step and two-step screening method and diagnostic criteria. MATERIALS AND METHODS: A retrospective cohort study was conducted among women screened using Carpenter and Coustan's (C&C) criteria (two-step method) and the International Association of the Diabetes and Pregnancy Study Groups (IADPSG) criteria (one-step method). All deliveries after 28 weeks of gestation, except for pregnancies complicated by pre-pregnancy diabetes mellitus, were analyzed. Multiple logistic regression was used to assess the associations between GDM and various potential risk factors. RESULTS: Risk factors for C&C-defined GDM were pre-pregnancy body mass index >24.2 kg/m2 (adjusted odds ratio [OR] 2.49, 95% confidence interval [CI] 1.92-3.23), maternal age at delivery >34 years (adjusted OR 2.46, 95% CI 1.96-3.09), history of fetal death (adjusted OR 2.56, 95% CI 1.37-4.78), and chronic hypertension (adjusted OR 3.66, 95% CI 1.50-8.91). In addition to these factors, conception assisted by reproductive technology (adjusted OR 1.64, 95% CI 1.19-2.25) and genetic amniocentesis (adjusted OR 1.19, 95% CI 1.03-1.38) were IADPSG-defined GDM risk factors. CONCLUSION: Risk factors for GDM differ with the diagnostic criteria used. This information is important when changing GDM screening strategies from the two-step approach to the one-step approach.

Lowered cutoff points of obesity indicators are better predictors of hypertension and diabetes mellitus in premenopausal Taiwanese women.

INTRODUCTION: In previous study, we found that in order to prevent MS in women aged <65 years, the cutoff points of obesity indicators should be lowered. OBJECTIVE: To investigate whether our proposed cutoff points of obesity indicators predict the occurrence of hypertension (HT), diabetes mellitus (DM), and hyperlipidemia in premenopausal women with greater sensitivity and specificity compared to reference cutoff points of obesity that are currently being used. METHODS: Using the database of the "2002 Survey on the Prevalence of Hypertension, Hyperglycemia and Hyperlipidemia in Taiwan" provided by the Bureau of Health Promotion, Taiwan as research material, data from 2270 premenopausal women aged 20-65 years were used for the analyses. The receiver-operating characteristic curves (ROC) of the body-mass index (BMI), waist circumference (WC), waist-to-hip ratio (WHR), and waist-to-height ratio (WHtR) were used to predict HT, DM, and hyperlipidemia. RESULTS: Obesity is not a good predictor of the occurrence of hyperlipidemia in premenopausal women aged <65 years. However, our proposed cutoff points had greater sensitivity and specificity than did the reference cutoff points. To prevent the risk of HT and DM in premenopausal women, the cutoff points of obesity indicators should be reduced. The proposed values are as follows: a WHR of 0.79; a WC of 74.7 cm; a WHtR of 0.49; and a BMI of 22.3 kg/m(2).

Low predictability of anthropometric indicators of obesity in metabolic syndrome (MS) risks among elderly women.

While diagnostic criteria for MS may vary depending on ethnicity, obesity remains a key risk factor in its development. In Taiwan, the incidence of obesity and MS among women has been increasing; however cut-off values for defining obesity for the diagnosis of MS among different groups of women have not been clearly established. The goal of this research was to examine the suitability of various anthropometric indicators of obesity in predicting the presence of MS criteria and to determine appropriate cut-off values of these indicators for women of different age and menstrual status. The sample was derived from the 2002 "Taiwan Three High Prevalence Survey" database. Women were divided into three groups based on age and menstrual status. Receiver-operating characteristic (ROC) curves was applied to the anthropometric indicators of obesity including, body mass index (BMI), waist circumference (WC), waist-to-hip ratio (WHR), waist-to-height ratio (WHtR), to ascertain its value in predicting MS. 2848 cases were included. It was found that most MS component values were worse with age and following menopause. Obesity indicators showed poor predictability for MS risks in post-menopausal women over 65 years, but good predictability in women under 65 years; our study revealed the following as ideal cut-off values for non-menopausal female: WHtR<0.49, WC<78 cm, WHR<0.79, BMI<24 kg/m(2); for menopausal women, WHtR<0.54, WC<83 cm, WHR<0.84, BMI<24.4 kg/m(2). It was concluded that obesity alone is not a reliable predictor of MS risks in women over the age of 65, and cut-off values for obesity indicators need to be further reduced in non-menopausal women.

Empowering: the experiences of exercise among heart transplantation patients in Taiwan.

AIM: To explore the experiences of exercise among Taiwanese heart transplant patients on the basis of a grounded theory. BACKGROUND: Although studies conducted around the world have proven how important exercise is to heart transplant patients, little information was found about heart transplant patients' exercise experience. In addition, because of different cultural backgrounds, people in Taiwan do not care about 'regular exercise' as much as Americans and Europeans do. Therefore, it is very important to find ways so that they can value 'regular exercise.' METHODS: In-depth interviews were undertaken with a purposive sample of eight heart transplant patients. Data was analysed by repeated verification. RESULTS: Eight valid cases were separately and thoroughly interviewed while they were exercising at a sports medical centre. The results revealed that 'empowering the new heart' is the core reason for their exercise. During the exercise training process, every participant felt that his or her new heart was filled with power or energy. The 'hardness and endurance' in terms of feeling discomfort in the body was identified at the beginning of post-surgical exercise training. Throughout the process of empowerment, patients experienced the following five interactive behaviour categories: 'self-protection', 'sharing', 'being watched and cared for', 'being aware of the benefits', and 'strengthening the new heart'. CONCLUSIONS: Exercise can empower the new heart. After the exercise training, all patients felt that their new hearts were empowered with energy and vigour, and thus were willing to continue exercising. They even expanded their regimen to include folk therapies such as Tai Chi and breathing exercises.
