The efficacy of a mindfulness-based exercise program in older residents of a long-term care facility in Taiwan.

Older people living in long-term care facilities remain largely inactive, and therefore promoting exercise in this population is necessary. This study evaluated the efficacy of a mindfulness-based exercise program in older residents of a long-term care facility in Taiwan. A convenience sample of 72 older residents of a long-term care facility were recruited and assigned to either an experimental group or a control group. The experimental group (n = 36) participated in an 8-week mindfulness-based exercise program, and the control group (n = 36) received routine care. The generalized estimating equation showed significantly larger improvements in a fear of falling, exercise self-efficacy, dynamic balance, and muscle strength in the experimental group than in the control group from baseline to the end of the intervention and 3 months after the end of the intervention. This study provides a reference for how to improve exercise practice in older people living in long-term care facilities.

[Application of Mindfulness-Based Health-Promotion Behavior in People With Chronic Diseases: SMILE Strategy].

Chronic diseases often impact the quality of life of the patient, causing complications and increased mortality and medical costs. The World Health Organization proposed applying mindfulness as an important strategy to help transform the situation faced by chronic disease cases and to promote their mental flexibility and adaptability. The author reviewed the related literature on mindfulness and introduces the "SMILE" strategy in this article. This strategy includes several stages, including 1) Starting where I am, 2) Motivating patients to become self-aware of the experience of self and internal and external environment interactions, 3) Developing individual health beliefs, 4) Learning mindfulness-based health-promotion behaviors, 5) Evaluating the efficacy of mindfulness-based health-promotion behaviors and self-regulation. SMILE is a powerful strategy with the potential to promote patient wellbeing, acceptance of the need to coexist with chronic disease, and freedom. Mindfulness is an abstract concept. This article provides a reference on mindfulness intervention for healthcare providers.

The Prophylactic Effect of Proton Pump Inhibitors Combined with Enteral Nutrition for Preventing Gastrointestinal Hemorrhage after Cardiovascular Surgery in High-Risk Patients.

BACKGROUND: Gastrointestinal hemorrhage (GH) is one of the most serious complications after cardiovascular surgery. The aim of the study was to provide an optimal therapeutic strategy for preventing postoperative GH in high-risk patients. METHODS: This retrospective case-control study included 188 adult patients at high risk of postoperative GH. These patients were divided into two groups based on a strategy for preventing postoperative GH: Group A (n = 97) received continuous intravenous infusion of proton-pump inhibitor (PPI) combined with early enteral nutrition, and Group B (n = 91) received a bolus intravenous infusion of PPI combined with late enteral nutrition. The clinical features of the groups were examined. RESULTS: The incidence of postoperative GH in the patients of group A was significantly lower than the patients in group B. The duration from the end of surgery to eating for the first time in the patients of group A was significantly shorter than in the patients of group B. A descending trend in 30-day mortality was observed in the patients of group A compared with group B, but no significant difference was found between the two groups. CONCLUSION: Continuous intravenous infusion of PPI combined with early enteral nutrition could effectively prevent GH and reduce 30-day mortality after cardiovascular surgery in high-risk patients.

Efficacy of a horticultural activity program for reducing depression and loneliness in older residents of nursing homes in Taiwan.

Promoting psychological health in older populations is important. This study evaluated a horticultural activity program for reducing depression and loneliness in older residents of nursing homes in Taiwan. A convenience sample of 150 older residents of three nursing homes were recruited and randomly assigned to either an experimental group or a control group. The experimental group (n = 75) participated in an 8-week horticultural activity program. The control group (n = 75) received routine care. Generalized estimating equations analyses revealed significant time by treatment interaction effects for depression (p < .001) and loneliness (p < .001). This study provides a reference for improving psychological health in older people.

Lifestyle in Visually Impaired or Blind Massage Therapists: A Preliminary Study.

BACKGROUND: Lifestyle is among the most important factors affecting individual health status. Limited access to health information may limit the ability of people with visual impairment or blindness to practice healthy lifestyles. However, no studies have investigated how lifestyle practices affect health specifically in visually impaired and blind populations. PURPOSE: The aim of this study was to investigate the lifestyle behaviors of visually impaired and blind massage therapists (VIBMTs) in Taiwan. METHODS: This exploratory study used a purposive sampling technique to recruit 50 VIBMTs who were employed at massage stations in southern Taiwan. All of the participants completed the Health-Promoting Lifestyle Profile II (HPLP-II) and a survey of demographic characteristics. Descriptive and inferential statistical tests, including the Mann-Whitney U test and the Kruskal-Wallis H test, were used. Statistical significance was defined as p < .05 in two-tailed tests. RESULTS: Fifty participants completed both the HPLP-II and the demographic survey. The mean subscale score for the HPLP-II was 2.52 ± 0.37. The lowest scores were on the physical activity (2.09 ± 0.67) and nutrition (2.35 ± 0.39) subscales, and the highest scores were on the spiritual growth (2.89 ± 0.56) and interpersonal relations (2.79 ± 0.46) subscales. Scores on the stress management and physical activity subscales were significantly higher in men than in women (p < .05). In addition, mean HPLP-II scores were significantly higher in VIBMTs who exercised regularly compared with those who did not (p < .05). Compared with nonsmokers, current smokers had significantly higher scores on the stress management subscale (p < .05). CONCLUSIONS/IMPLICATIONS FOR PRACTICE: The low physical activity scores in this population may be improved by developing physical activity programs for the home and workplace and by establishing community recreational and exercise facilities for visually impaired populations. The low scores for nutrition may be improved by establishing nutrition education programs that are designed specifically for VIBMTs to increase their consumption of fresh produce and other healthy foods and by requiring food manufacturers to use labels that may be easily read or understood by visually impaired populations.

Curcumin Induces p53-Null Hepatoma Cell Line Hep3B Apoptosis through the AKT-PTEN-FOXO4 Pathway.

OBJECTIVE: Curcumin (diferuloylmethane) is a yellow-colored polyphenol with antiproliferative and proapoptotic activities to various types of cancer cells. This study explored the mechanism by which curcumin induces p53-null hepatoma cell apoptosis. RESULTS: AKT, FOXO1, and FOXO3 proteins were downregulated after curcumin treatment. Conversely, PTEN was upregulated. Subcellular fractionations revealed that the FOXO4 protein translocated from cytosol into the nucleus after curcumin treatment. Overexpression of FOXO4 increases the sensitivity of Hep3B cells to curcumin. Knockdown of the FOXO4 gene by siRNA inhibits the proapoptotic effects of curcumin on Hep3B cell. CONCLUSIONS: This study revealed the AKT/PTEN/FOXO4 pathway as a potential candidate of target for treatment of p53-null liver cancers.

Anti-tumor effect of Radix Paeoniae Rubra extract on mice bladder tumors using intravesical therapy.

Radix Paeoniae Rubra (RPR) is the dried root of Paeonia lactiflora Pallas and Paeonia veitchii Lynch, and is a herbal medicine that is widely used in traditional Chinese medicine for the treatment of blood-heat and blood-stasis syndrome, similarly to Cortex Moutan. The present study identified the same three components in RPR and Cortex Moutan extracts. In addition, it has been reported that RPR has an anti-cancer effect. Bladder cancer is the seventh most common type of cancer worldwide. Due to the high recurrence rate, identifying novel drugs for bladder cancer therapy is essential. In the present study, RPR extract was evaluated as a bladder cancer therapy in vitro and in vivo. The present results revealed that RPR extract reduced the cell viability of bladder cancer cells with a half maximal inhibitory concentration of 1-3 mg/ml, and had an extremely low cytotoxic effect on normal urothelial cells. Additionally, RPR decreased certain cell cycle populations, predominantly cells in the G1 phase, and caused a clear sub-G increase. In a mouse orthotopic bladder tumor model, intravesical application of RPR extract decreased the bladder tumor size without altering the blood biochemical parameters of the mice. In summary, the present results demonstrate the anti-proliferative properties of RPR extract on bladder cancer cells, and its anti-bladder tumor effect in vivo. Compared to Cortex Moutan extract, RPR extract may provide a more effective alternative therapeutic strategy for the intravesical therapy of superficial bladder cancer.

Oroxylin a, but not vasopressin, ameliorates cardiac dysfunction of endotoxemic rats.

The mortality in septic patients with myocardial dysfunction is higher than those without it. Beneficial effects of flavonoid oroxylin A (Oro-A) on endotoxemic hearts were evaluated and compared with that of arginine vasopressin (AVP) which is used to reverse hypotension in septic patients. Endotoxemia in rats was induced by one-injection of lipopolysaccharides (LPS, 10 mg/kg, i.p.), and hearts were isolated 5-hrs or 16-hrs later. Isolated hearts with constant-pressure or constant-flow mode were examined by Langendorff technique. Rate and force of contractions of isolated atrial and ventricular strips were examined by tissue myography. Isolated endotoxemic hearts were characterized by decreased or increased coronary flow (CF) in LPS-treated-for-5hr and LPS-treated-for-16-hr groups, respectively, with decreased inotropy in both groups. Oro-A-perfusion ameliorated while AVP-perfusion worsened the decreased CF and inotropy in both preparations. Oro-A and AVP, however, did not affect diminished force or rate of contraction of atrial and ventricular strips of endotoxemic hearts. Oro-A-induced CF increase was not affected following coronary endothelium-denudation with saponin. These results suggest that Oro-A ameliorates LPS-depressed cardiac functions by increasing CF, leading to positive inotropy. In contrast, AVP aggravates cardiac dysfunction by decreasing CF. Oro-A is a potentially useful candidate for treating endotoxemia complicated with myocardial dysfunction.

Asymmetric dimethylarginine induces TNF-alpha production via ROS/NF-kappaB dependent pathway in human monocytic cells and the inhibitory effect of reinioside C.

Asymmetric dimethylarginine (ADMA), an endogenous nitric oxide synthase (NOS) inhibitor, has been implicated in vascular inflammation through induction of reactive oxygen species (ROS) and proinflammatory genes in endothelial cells. However, relatively few attentions have been paid to the effect of ADMA on monocytes, one of the important cells throughout all stages of atherosclerosis. In the present study, we found that reinioside C, the main component extracted from Polygala fallax Hemsl., dose-dependently inhibited tumor necrosis factor-alpha (TNF-alpha) production induced by ADMA in monocytes, Furthermore, reinioside C attenuated ADMA-induced generation of reactive oxygen species and activation of nuclear factor-kappaB (NF-kappaB) activity in monocytes in a dose-dependent manner, this effect was inhibited by l-arginine (NOS substrate) and PDTC (inhibitor of NF-kappaB). These data suggest that reinioside C could attenuate the increase of TNF-alpha induced by exogenous ADMA through inhibition ROS/NF-kappaB pathway in monocytes.

The effectiveness of hospital-based diabetes case management: an example from a northern Taiwan regional hospital.

The aim of this study was to design, implement and evaluate disease outcomes at a regional hospital- based case management program of care for patients with type 2 diabetes. A medical team and practice guidelines were established in line with the health insurance strategy of Taiwan's Bureau of National Health Insurance (BNHI) and American Diabetes Association (ADA) Standards of Care for Diabetes (2003 edition). Also, a set of self-care booklets was designed suitable for use by the subject group. The study was prospective and followed the patients from enrollment to one year. Patient outcomes were determined based on laboratory examinations and recorded self-care behavior. Data were collected at enrollment and over 4 follow-up times within a one year period. Generalized Estimating Equation (GEE) multiple linear regression and logistic regression were used for repeated measurements and adjustments of the effects of specific prognostic factors. Sixty subjects diagnosed with type 2 diabetes (mean duration 3.25 years) were recruited. All participants were married with a mean age of 52.5 years. A majority (58.3%) was male and 65% were ethnic Hakka. Self-care knowledge and behavior accomplishment rates were: taking medications by oneself, 91.3% (knowing medicines, 25.4%); hypoglycemia management, 23.3%; monitoring blood sugar, 46.7%; exercise, 35.8%; diet management, 51.7% and foot care, 92.8%. Significantly improved ADA diabetes care standard items included HbA1C (p< .0001), fasting glucose (p< .01) and triglycerides (p< .05). The study incorporated evidence-based guidelines, public health insurance strategies and self-care booklets into a protocol to provide comprehensive care. The implemented diabetes program achieved diabetes care goals and improved patient self-care.

[A clinical study of pelvic floor electrical stimulation in treatment of overactive bladder].

OBJECTIVE: To observe the efficacy of electrical stimulation in treatment of overactive bladder (OAB). METHODS: Patients (n = 60) with overactive bladder were randomly divided into 2 groups. Electrical stimulation group (n = 35) used an instrument for electrical stimulation through a special vagina or rectum probe transfer current (8-70 mA), for 20 min, qd, for 20-30 times. Medical group (n = 25) received oral tolterodine 2 mg, bid, for 2-4 weeks. RESULTS: The total effective rate and cure rate were 74%, 37% in electrical stimulation group and 76%, 40% in medical group, respectively, showing no significant difference between two groups (P > 0.05). While patients' satisfactory rate was significantly higher in electrical stimulation group than in medical group (P < 0.05). Side effects were more commonly seen with tolterodine. CONCLUSIONS: Electrical nerve stimulation is effective and safe for overactive bladder. Further studies are needed to show the long term efficacy and cost-effectiveness.
