Diet Pattern Analysis in Alzheimer's Disease Implicates Gender Differences in Folate-B12-Homocysteine Axis on Cognitive Outcomes.

BACKGROUND & AIMS: Low plasma B12 and folate levels or hyperhomocysteinemia are related to cognitive impairment. This study explores the relationships among diet pattern, blood folate-B12-homocysteine levels, and cognition measurement in Alzheimer's disease (AD) while exploring whether a gender effect may exist. METHODS: This cross-sectional study enrolled 592 AD patients (246 males, 346 females) and the demographic data, blood biochemical profiles, Mini-Mental State Examination (MMSE), and a Food Frequency Questionnaire (FFQ) for quantitative assessment of dietary frequency were collected. Structural Equation Modeling (SEM) was employed to explore the associations among dietary patterns, blood profiles, and cognition. A least absolute shrinkage and selection operator regression model, stratified by gender, was constructed to analyze the weighting of possible confounders. RESULTS: Higher MMSE scores were related to higher frequencies of coffee/tea and higher educational levels, body mass index, and younger age. The SEM model revealed a direct influence of dietary frequencies (skimmed milk, thin pork, coffee/tea) and blood profiles (homocysteine, B12, and folate) on cognitive outcomes. At the same time, the influence of dietary pattern on cognition was not mediated by folate-B12-homocysteine levels. In males, a direct influence on the MMSE is attributed to B12, while in females, homocysteine is considered a more critical factor. CONCLUSIONS: Dietary patterns and blood profiles are both associated with cognitive domains in AD, and there are gender differences in the associations of dietary patterns and the levels of B12 and homocysteine. To enhance the quality of dietary care and nutritional status for individuals with dementia, our study results still require future validations with multi-center and longitudinal studies.

A Biomarker of Stress and Self-reported Caregiving Distress Predict Poor Quality of Life in Family Caregivers of Patients With Heart Failure.

BACKGROUND: Family caregivers are at a high risk for low quality of life due to caregiving-related stress. Caregivers' stress is commonly assessed using self-reported measures, which reflect relatively subjective and long-term stress related to caregiving, but objective biological markers of stress are rarely used for caregivers. The purposes of this study were (1) to determine whether caregiver characteristics were associated with stress assessed using a stress biomarker (serum cortisol) and a self-reported caregiving distress measure (Caregiver Burden Inventory) and (2) to determine the predictability of both stress measures for quality of life in caregivers of patients with heart failure. METHODS: Taiwanese family caregivers (N = 113; mean age, 54.5 years; 70.8% female) of patients with heart failure completed surveys including caregiving distress and quality of life measured by the Caregiver Burden Inventory and the Short Form-36 (physical and psychological well-being subscales), respectively, and provided blood samples for serum cortisol. Independent t tests, correlation, and hierarchical regression were conducted. RESULTS: Single caregivers had higher serum cortisol levels than married caregivers (P = .002). Men had significantly higher serum cortisol levels than women (P = .010), but men reported lower caregiving distress than women (P = .049). Both serum cortisol (ß = -0.32, P = .012) and caregiving distress (ß = -0.29, P = .018) were significant predictors of quality of life in the physical well-being scale while controlling for caregivers' characteristics and depressive symptoms. Serum cortisol (ß = -0.28, P = .026) and caregiving distress (ß = -0.25, P = .027) also predicted quality of life in the psychological well-being scale. CONCLUSIONS: Serum cortisol and self-reported caregiving distress have similar predictability for quality of life in family caregivers of patients with heart failure. Reducing stress and caregiving distress is critical to improving quality of life in this population.

Relationships between Willingness to Participate in the Nursing Clinical Ladder Program and Its Related Factors among Clinical Nurses.

The professional nursing competence ladder system can effectively inspire nurses' work morale, improve quality of life, and avoid the issue of senior staff leaving the clinical setting. The aim of this study was to explore the willingness to participate in the professional nursing competence ladder system and its related factors among nurses. A cross-sectional study design with a structured questionnaire was used. Purposive sampling was employed, and 696 nurses who qualified to be promoted as N2 were recruited from a medical center in southern Taiwan. The results showed most nurses were willing to participate in the nursing ladder system. There were significant differences between willingness to participate in the ladder system and age, education level, as well as promotion experience. This study emphasizes the importance of intensifying internal encouraging factors and strengthening external encouraging factors to improve participation rates. Healthcare institutions could provide instruction on case report writing to increase nurses' willingness to participate in the clinical ladder program.

Musculoskeletal disorders, psychosocial stress and associated factors among home-based migrant care workers.

BACKGROUND: Prevalence of musculoskeletal disorders (MSDs) and psychological stress in home-based female migrant care workers (MCWs) remain unknown. OBJECTIVE: To 1) investigate the prevalence of MSDs and psychological stress and associations between subjective questionnaires on MSDs/psychological stress and biomedical examinations, and 2) identify the risk factors related to MSDs and psychological stress. METHODS: This study recruited 85 MCWs. Data was collected using questionnaires, urine analysis and X-ray examinations. Correlations between subjective questionnaires and biomedical examinations were investigated. Multivariable logistic regression analyses were used to explore risk factors. RESULTS: The prevalence of MSDs and psychological stress were 70.6% and 37.6%, respectively. MSDs were commonly reported over the neck, lower back, shoulders, and upper back. There was a moderate correlation between MSDs and abnormal X-ray findings. Risk factors associated with MSDs included higher education level, frequent transferring and bedside care activities, lacking caregiver training in Taiwan, inadequate sleep, and drinking tea or coffee. Risk factors associated with psychological stress included inadequate salary, lacking caregiver training in Taiwan, and insufficient knowledge of body mechanics techniques. CONCLUSIONS: MSDs and psychological stress were common among home-based female MCWs. Educational level, frequent transferring and bedside care activities, and lack of caregiver training in Taiwan, were the most dominant risk factors.

Adjunctive Hyperbaric Oxygen Therapy for Healing of Chronic Diabetic Foot Ulcers: A Randomized Controlled Trial.

PURPOSE: The purpose of this study was to compare the effect of standard wound care with adjunctive hyperbaric oxygen therapy (HBOT) to standard wound care alone on wound healing, markers of inflammation, glycemic control, amputation rate, survival rate of tissue, and health-related quality of life in patients with diabetic foot ulcers (DFUs). DESIGN: Prospective, randomized, open-label, controlled study. SUBJECTS AND SETTING: The sample comprised 38 patients with nonhealing DFUs who were deemed poor candidates for vascular surgery. Subjects were randomly allocated to an experimental group (standard care plus HBOT, n = 20) or a control group (standard care alone, n = 18). The study setting was a medical center in Kaohsiung City, Taiwan. METHODS: Hyperbaric oxygen therapy was administered in a hyperbaric chamber under 2.5 absolute atmospheric pressure for 120 minutes; subjects were treated 5 days a week for 4 consecutive weeks. Both groups received standard wound care including debridement of necrotic tissue, topical therapy for Wagner grade 2 DFUs, dietary control and pharmacotherapy to maintain optimal blood glucose levels. Wound physiological indices were measured and blood tests (eg, markers of inflammation) were undertaken. Health-related quality of life was measured using the Medical Outcomes Study 36-Item Short Form. RESULTS: Complete DFU closure was achieved in 5 patients (25%) in the HBOT group (n = 20) versus 1 participant (5.5%) in the routine care group (n = 18) (P = .001). The amputation rate was 5% for the HBOT group and 11% for the routine care group (χ = 15.204, P = .010). The HBOT group showed statistically significant improvements in inflammation index, blood flow, and health-related quality of life from pretreatment to 2 weeks after the last therapy ended (P < .05). Hemoglobin A1c was significantly lower in the HBOT group following treatment (P < .05) but not in the routine care group. CONCLUSIONS: Adjunctive HBOT improved wound healing in persons with DFU. Therapy also reduced the risk of amputation of the affected limb. We assert that at least 20 HBOT sessions are required to be effective.

A Decade of Changes in Family Caregivers' Preferences for Life-Sustaining Treatments for Terminally Ill Cancer Patients at End of Life in the Context of a Family-Oriented Society.

CONTEXT: Temporal changes in different family caregiver cohorts' preferences for life-sustaining treatments (LSTs) at end of life (EOL) have not been examined nor have the concept of whether caregivers' LST preferences represent a homogeneous or heterogeneous construct. Furthermore, LST preferences are frequently assessed from multiple treatments, making clinical applications difficult/infeasible. OBJECTIVES: To identify parsimonious patterns and changes in the pattern of LST preferences for two independent cohorts of family caregivers for terminally ill Taiwanese cancer patients. METHODS: Preferences for cardiopulmonary resuscitation, intensive care unit care, cardiac massage, intubation with mechanical ventilation, intravenous nutritional support, tube feeding, and dialysis were assessed among 1617 and 2056 family caregivers in 2003-2004 and 2011-2012, respectively. Patterns and changes in LST preferences were examined by multigroup latent class analysis. RESULTS: Five distinct classes were identified: uniformly preferring, uniformly rejecting, uniformly uncertain, and favoring nutritional support but rejecting or uncertain about other treatments. Class probability significantly decreased from 29.3% to 23.7% for the uniformly rejecting class, remained largely unchanged for the uniformly preferring (16.9%-18.6%), and favoring nutritional support but rejecting (37.1%-37.5%) or uncertain about other treatments (8.0%-10.4%) classes, but significantly increased from 7.0% to 11.5% for the uniformly uncertain class over time. CONCLUSION: Family caregivers' LST preferences for terminally ill cancer patients are a heterogeneous construct and shifted from uniformly rejecting all LSTs toward greater uncertainty. Surrogate EOL-care decision making may be facilitated by earlier and thorough assessments of caregivers' LST preferences and tailoring interventions to the unique needs of caregivers in each class identified in this study.

[The use of music intervention in nursing practice for elderly dementia patients: a systematic review].

BACKGROUND: Although music therapy is now applied widely as an intervention for elderly dementia patients, the effectiveness of this therapy is not yet well understood. PURPOSE: This study conducts a systematic review of clinical studies that address the effectiveness of music therapy in elderly dementia patients. METHODS: Databases including MEDLINE, Cochrane Library, ProQuest, EBMR, CINAHL, and CEPS were searched for relevant articles published between 2004 and 2013 using the key words "music" or "music therapy" with "dementia". An initial 272 original articles were identified. Applying inclusion criteria and excluding duplications left 18 articles that used randomized controlled trials to assess the effectiveness of music therapy in elderly participants for further analysis and synthesis. RESULTS: Music therapy was found effective at improving cognitive functions, mental symptoms, and eating problems. However, this therapy was not found effective at improving irritable behavior. Type of music and method of presentation were the most important factors affecting results. Most studies (61.1%) used songs familiar to ÷ favored by the participants; most studies delivered 30-minute interventions twice weekly; and most studies used a therapy duration of 6 hours. Finally, most studies (77.8%) had music therapy sessions performed by either music therapists or trained healthcare providers. CONCLUSIONS / IMPLICATIONS FOR PRACTICE: This study supports that music therapy is an effective nursing intervention for elderly dementia patients. The authors hope that findings are a helpful reference for clinical nurses to develop practical music therapy procedures and protocols.

[Factors of influence on willingness to participate in the N3 nursing clinical ladder program].

BACKGROUND: The professional nursing clinical ladder program can effectively enhance the professional morale of nursing staff and help retain the best senior nurses in clinical settings. Hence, it is important to explore factors that influence nurse staff intentions to participate in the clinical ladder. PURPOSE: This study examined factors that affect nurse staff intention to participate in the N3 nurse clinical ladder program. METHODS: We used a cross sectional study design and a structured questionnaire survey. We employed purposive sampling to recruit 389 nurse staffs qualified for promotion to the N3 level from a medical center in southern Taiwan. RESULTS: Findings showed: (1) Nearly two-thirds (233, 59.9%) of participants intended to participate in clinical ladder; (2) The factors of age, years of nursing experience, years in current position, project/research experience, promotion experience, and intention all significantly affected intent to participate in the ladder; (3) A significant difference between willingness to participate in the ladder program and each of the following variables--motivation, satisfaction, professional capacity, and sense of achievement; (4) Logistic regression analysis identified only motivation as a valid predictor of willingness to participate the ladder program (95% CI: 1.21-3.78). CONCLUSION/IMPLICATIONS FOR PRACTICE: Results provide a useful reference to nursing administrators for planning on-the-job training and increasing nurse staff participation in the ladder. The authors hope results can help promote better human resource management and achievements.
