Estimate prevalence of cognitive problems due to hypoxic brain injury in out-of-hospital cardiac arrest (OHCA) survivors referred for cardiac rehabilitation and association with quality of life as well as autonomy and participation. Prospective cohort study. Consecutive OHCA patients. The Mini-Mental State Examination (MMSE), Cognitive Failures Questionnaire (CFQ) and Informant Questionnaire on Cognitive Decline in the Elderly (IQCODE) were administered 4 weeks after the OHCA. Cognitive problems were defined if MMSE <28, CFQ >32 or IQCODE >3.6. The Impact on Participation and Autonomy Questionnaire (IPAQ) (participation/autonomy), the SF-36 Health Survey (SF-36) (quality of life) and the Hospital Anxiety Depression Scale (HADS) (anxiety/depression) were administered. Correlations between cognitive problems and participation/autonomy and quality of life were calculated. 63 of 77 patients were male (82%), median age 59 years (range 15-84). MMSE median 29 (interquartile range 28-30), CFQ mean 20.9 (SD 9.4) and IQCODE mean 3.1 (SD 0.2). Eighteen patients (23%) scored positive for cognitive problems. Significant correlations were found between MMSE and IPAQ: autonomy inside (r = -0.38), family role (r = -0.26), autonomy outside (r = -0.32), social relations (r = -0.38) and social functioning (r = 0.32). MMSE was related to SF-36: social functioning (r = 0.32). The CFQ was related to IPAQ: autonomy outdoors (r = 0.29) and SF-36: bodily pain (r = -0.37), vitality (r = -0.25), mental health (r = -0.35) and role emotional (r = -0.40). The IQCODE was related to IPAQ: autonomy indoors (r = 0.26) and to SF-36: vitality (r = -0.33) and social functioning (r = -0.41). Twenty-three percent of the patients referred for cardiac rehabilitation showed cognitive problems. Associations were found between cognitive problems and several aspects of participation/autonomy and perceived quality of life. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

Heart failure is one of the major chronic diseases that affect health related quality of life. The objective of this study was to evaluate the quality of life in patients with New York Heart Association functional class I-III using the SF-36 on a cohort of survivors of the EPICOUR Study Group and compare the quality of life with the general Spanish population of the same sex and age group. A cohort study, observational, and prospective study was conducted on survivors of the EPICOUR Study Group, on whom a clinical-progression-outcome review was performed along with the SF-36. The quality of life was studied in 50 patients (60% male). The average age of men was 64.8 years and women 68.3. When analyzing the SF-36, it was observed that the results were lower in the physical dimensions than in the mental dimensions. The quality of life worsened with increasing functional class (statistically significant differences for scales of physical functioning, social functioning and borderline significance in mental health scale). When comparing patients with the general population of the same age and sex, patients with heart failure showed lower scores on all scales (significant differences in physical functioning, body pain, vitality, and social role for men, and physical function and emotional role for women). Heart failure causes a negative impact on quality of life, physical functioning, as well as psychosocial function, with the impairment becoming worse with increased functional class.

Although the relationship of obsessive-compulsive symptoms (OCSs) with both cognition and social functioning (SF) has already been the focus of research in schizophrenia, the moderation of the relationship of OCSs with SF by cognition has not been explored to date. We investigated the association of OCSs with SF and its interaction with cognition in schizophrenia. We recruited 110 schizophrenia patients and assessed OCSs (Yale-Brown Scale), schizophrenia symptoms (Positive and Negative Syndrome Scale), SF (Strauss-Carpenter Scale) and cognition. 51 patients had one obsessive-compulsive symptom or more, whereas 59 patients had no obsessive compulsive-symptom, according to the Yale-Brown Scale. We mainly investigated: a) the predictive effect of OCSs on SF, controlling for cognition, illness duration and symptoms' severity and b) the moderating effect of cognition on the OCSs-SF relationship. The mean score of OCSs for patients having at least one symptom was 13.43 (SD=8.32). Higher OCSs predicted increased SF (B=0.98, t=2.41, df=88, p=0.018). This relationship was driven by the association of compulsions with job functioning (B=0.074, t=2.029, df=88, p=0.046). Patients without OCSs demonstrated worse functioning compared with those having at least one obsessive-compulsive symptom (mean difference=2.496, t=3.732, df=88, p<0.001). We failed to find evidence that cognition moderates the effect of OCSs on SF. There may be a beneficial effect of OCSs on SF in patients with schizophrenia which is independent of their cognitive performance. Copyright © 2016 Elsevier Inc. All rights reserved.

To examine the responsiveness of Functional Assessment of Cancer Therapy-Prostate (FACT-P) and Short Form-12 Health Survey version 2 (SF-12 v2) in prostate cancer patients because there is a lack of evidence to support their responsiveness in this patient population. One hundred sixty-eight subjects with prostate cancer were surveyed at baseline and at 6 months using the SF-12 v2 and FACT-P version 4. Internal responsiveness was assessed using paired t test and generalized estimating equation. External responsiveness was evaluated using receiver operating characteristic curve analysis. The internal responsiveness of the FACT-P and SF-12 v2 to detect positive change was satisfactory. The FACT-P and SF-12 v2 could not detect negative change. The FACT-P and the SF-12 v2 performed the best in distinguishing between improved general health and worsened general health. The FACT-P performed better in distinguishing between unchanged general health and worsened general health. The SF-12 v2 performed better in distinguishing between unchanged general health and improved general health. Positive change detected by these measures should be interpreted with caution as they might be too responsive to detect "noise," which is not clinically significant. The ability of the FACT-P and the SF-12 v2 to detect negative change was disappointing. The internal and external responsiveness of the social well-being of the FACT-P cannot be supported, suggesting that it is not suitable to longitudinally monitor the social component of HRQOL in prostate cancer patients. The study suggested that generic and disease-specific measures should be used together to complement each other.

Abstracts Background: Arm lymphedema after breast cancer surgery affects women both from physical and psychological points of view. Lymphedema leads to adipose tissue deposition. Liposuction and controlled compression therapy (CCT) reduces the lymphedema completely. Methods and Results: Sixty female patients with arm lymphedema were followed for a 1-year period after surgery. The 36-item short-form health survey (SF-36) was used to assess health-related quality of life (HRQoL). Patients completed the SF-36 questionnaire before liposuction, and after 1, 3, 6, and 12 months. Preoperative excess arm volume was 1365 ± 73 mL. Complete reduction was achieved after 3 months and was sustained during follow-up. The adipose tissue volume removed at surgery was 1373 ± 56 mL. One month after liposuction, better scores were found in mental health. After 3 months, an increase in physical functioning, bodily pain, and vitality was detected. After 1 year, an increase was also seen for social functioning. The physical component score was higher at 3 months and thereafter, while the mental component score was improved at 3 and 12 months. Compared with SF-36 norm data for the Swedish population, only physical functioning showed lower values than the norm at baseline. After liposuction, general health, bodily pain, vitality, mental health, and social functioning showed higher values at various time points. Conclusions: Liposuction of arm lymphedema in combination with CCT improves patients HRQoL as measured with SF-36. The treatment seems to target and improve both the physical and mental health domains. PMID:28135120

This phase 3 study evaluated quality of life, functioning, and productivity after treatment with extended-release (ER) hydrocodone formulated with CIMA ® Abuse-Deterrence Technology platform. Patients with chronic pain were rolled over from a 12-week placebo-controlled hydrocodone ER study or were newly enrolled. Hydrocodone ER doses were titrated (15 to 90 mg every 12 hours) to an analgesic dose, and patients received up to 52 weeks of open-label treatment. Assessments included Clinician Assessment of Patient Function (CAPF), Patient Assessment of Function (PAF), Brief Pain Inventory-Short Form (BPI-SF), 36-item Short-Form Health Survey (SF-36), Sheehan Disability Scale (SDS), and World Health Organization Health and Work Performance Questionnaire-Short Form (HPQ-SF). Of 330 enrolled patients, 291 composed the full analysis population. By week 4, ≥ 50% of patients showed improvement from baseline in all 5 CAPF domains (general activities, walking, work/daily living, relationships, and enjoyment of life) and 6 of 7 PAF domains (work attendance, work performance, walking, exercise, socializing, and enjoying life). Mean decreases from baseline of 2 to 3 points were noted for BPI-SF pain interference questions from week 4 through endpoint. Mean improvements from baseline to endpoint in SF-36 subscales ranged from 3.3 to 22.3, and SDS scores improved from moderate (4.8 to 5.1) to mild (2.5 to 2.8) disruptions in work/school, social life, and family life. At endpoint, mean HPQ-SF absolute absenteeism scores decreased from 13.6 to 10.0 hours lost/month and absolute presenteeism scores improved from 67.0 to 77.1. Patients receiving hydrocodone ER showed early numeric improvements in functioning that continued throughout this 12-month study. © 2016 World Institute of Pain.

We examined the relationship between the swallowing function and the health-related QOL (quality of life) among community-dwelling dependent elderly persons. The subjects included 191 community-dwelling dependent elderly persons. Data were collected via questionnaires, including information regarding age, gender, the level of care required, post-cerebrovascular disease, the health-related QOL and the swallowing function. We used the SF-8 to measure the health-related QOL and the DRACE (Dysphagia Risk Assessment for the Community-dwelling Elderly) to evaluate the swallowing function. The average DRACE score was 4.29±3.81. In addition, the swallowing risk was found to be related to the SF (social functioning) and MH (mental health) subscales of the SF-8. Our results suggest that the swallowing function is significantly related to the health-related QOL among community-dwelling dependent elderly persons.

The high emotional burden of physicians working in emergency departments may affect their quality of life perception. To evaluate health related quality of life among resident physicians performing shifts at an emergency department. Seventy one physicians aged 26,3 ± 1,7 years (47 women), working as residents in an emergency department, answered the short version of the Short-Form Health Survey Questionnaire (SF-36®). This questionnaire analyses eight domains: physical function, body pain, general health, vitality, social function, emotional role and mental health. Women had a significantly worse perception than a reference population in four dimensions of the SF-36, especially mental health and social functioning. Men had scores similar to the reference population. Among women, vitality is the best predictor of mental health and social functioning. Women working as residents in an emergency department have a worse perception of their quality of life than men performing the same job.

In brain tumor (BT) patients, the association between health-related quality of life (HRQoL) and psychological characteristics remains largely unknown. We evaluated the association of personality traits, clinical factors, psychological distress symptoms, and cognitive state with HRQoL in BT patients. On admission for BT surgery, 200 patients (69 % women; age 55.8 ± 14.5 years) were evaluated for HRQoL (SF-36 scale), Big-Five personality traits (Ten-Item Personality Inventory), psychological distress symptoms (Hospital Anxiety and Depression Scale or HADS), cognitive function (Mini-Mental State Examination or MMSE) and clinical characteristics, including functional status (Barthel index or BI). The most common BT diagnoses were meningioma (39 %) and high-grade glioma (18 %). Only factors significantly associated with SF-36 domains in univariable regression analyses were included in their respective multivariable models and predicted from 6 %-49 % of the total variance of SF-36 scores. Greater TIPI emotional stability score was independently associated with greater SF-36 emotional well-being (β = 0.23, p < 0.001) and general health (β = 0.18, p = 0.01) scores, and greater TIPI consciousness score, with greater SF-36 emotional well-being score (β = 0.13, p = 0.02). HADS-anxiety and HADS-depression scores were the strongest independent determinants of all, except physical functioning, SF-36 scores (β-values range from 0.14 to 0.56; p values ≤ 0.03). BI score was the strongest independent determinant of SF-36 physical functioning score (β = 0.36, p < 0.001). MMSE score was associated with all but emotional well-being and social functioning SF-36 scores. Consciousness and emotional stability should be considered important personality-related determinants of HRQoL in BT patients. Psychological distress, functional disability, and cognitive impairment are also important predictors of HRQoL.

Few studies have examined the association between social support and health-related quality of life (HRQOL) among nursing home residents and whether the sense of coherence (SOC) modifies the effect of social support on health-related quality of life. The main aims of this study were to determine the relationship between social support and HRQOL and to investigate whether the SOC modifies the effect of social support on HRQOL. A cross-sectional, descriptive, correlational design. All 30 nursing homes in Bergen in western Norway. Two hundred and twenty-seven mentally intact long-term nursing home residents 65 years and older. Data were obtained through face-to-face interviews using the SF-36 Health Survey, Social Provisions Scale and Sense of Coherence Scale. Possible relationships between the Social Provisions Scale and the eight SF-36 subdimensions were analysed using multiple linear regression while controlling for age, sex, marital status, education and comorbid illness. Interactions between the Sense of Coherence Scale and Social Provisions Scale were investigated. Attachment affected the mental health subdimension (p=0.001), opportunity for nurturance affected social functioning (p=0.003) and reassurance of worth affected vitality (p=0.001) after adjustment for demographic variables and comorbid illness. After the analysis included the sense of coherence, nurturance still significantly affected social functioning and reassurance of worth still significantly affected vitality. No interaction with sense of coherence was found, and sense of coherence significantly affected all SF-36 subdimensions. The opportunity to provide nurturance for others appears to be important for social functioning, and sense of competence and sense of self-esteem appear to be important for vitality. Further, the residents' relationships with significant others comprise an important component of mental health. Finally, independent of the level of sense of coherence, social support is an important resource for better health-related quality of life. Clinical nurses should recognize that social support is associated with health-related quality of life and pay attention to the importance of social support for the residents in daily practice.

Lifestyle moderate-intensity physical activity can lower the risk of over twenty chronic health conditions, whilst inactivity reduces daily functioning and physical health of individuals living with schizophrenia. This study conducted in 2014 examines the effect of structured walking participation on QOL, psychosocial functioning and symptoms in Hospital Permai, one of the largest psychiatry institution in Asia Chronic patients with schizophrenia (n=104) who met inclusion criteria were randomised to either a 3-month structured walking intervention or a treatment-as-usual arm. The Positive and Negative Syndrome Scale (PANSS), global functioning (PSP) and QOL (SF-36) were measured at baseline and after the 3-month interval. At 3 month follow-up, there were significant within group differences in QOL (SF-36), psychiatric symptoms (PANSS), and personal and social performance (PSP). There were statistically significant increase in the median SF-36 scores, with increases shown in physical functioning (p<.001), physical role limitations (p<.05), social functioning (p<.01) in the intervention group compared to treatment-as-usual group. Statistically significant reduction of median PANSS score of the intervention group were noted in positive (p<0.001) and negative (p<0.01) symptom, and general psychopathology (p<0.01) scales. Statistically significant increase in the median PSP score (p<0.01) was found in the intervention group compared with the treatment-as-usual group. Between-group differences at post intervention (favouring Intervention) were significant for PANSS positive and SF36 Physical In long stayed chronic inmates, a simple but consistent, organized walking intervention has the potential to bring improvement in functioning, reduction in psychiatric symptoms and quality of Life. The emphasis of rehabilitation should target at lifestyle redesign intervention.

The dimensional personality disorders model in the Diagnostic and Statistical Manual (DSM)-5 section III conceptually differentiates impaired personality functioning (criterion A) from the presence of pathological traits (criterion B). This study is the first to specifically address the measurement of criterion A in older adults. Moreover, the convergent/divergent validity of criterion A and criterion B will be compared in younger and older age groups. The Severity Indices of Personality Functioning - Short Form (SIPP-SF) was administered in older (N = 171) and younger adults (N = 210). The factorial structure was analyzed with exploratory structural equation modeling. Differences in convergent/divergent validity between personality functioning (SIPP-SF) and pathological traits (Personality Inventory for DSM-5; Dimensional Assessment of Personality Pathology-Basic Questionnaire) were examined across age groups. Identity Integration, Relational Capacities, Responsibility, Self-Control, and Social Concordance were corroborated as higher order domains. Although the SIPP-SF domains measured unique variation, some high correlations with pathological traits referred to overlapping constructs. Moreover, in older adults, personality functioning was more strongly related to Psychoticism, Disinhibition, Antagonism and Dissocial Behavior compared to younger adults. The SIPP-SF construct validity was demonstrated in terms of a structure of five higher order domains of personality functioning. The instrument is promising as a possible measure of impaired personality functioning in older adults. As such, it is a useful clinical tool to follow up effects of therapy on levels of personality functioning. Moreover, traits were associated with different degrees of personality functioning across age groups.

Background: Early-onset major depressive disorder (MDD) (EOD) is often particularly malignant due to its special clinical features, accompanying impaired social function, protracted recovery time, and frequent recurrence. This study aimed to observe the effects of age onset on clinical characteristics and social function in MDD patients in Asia. Methods: In total, 547 out-patients aged 18–65 years who were from 13 study sites in five Asian countries were included. These patients had MDD diagnose according to the Diagnostic and Statistical Manual of Mental Disorders, 4th Edition criteria. Clinical features and social function were assessed using Symptom Checklist-90-revised (SCL-90-R) and Sheehan Disability Scale (SDS). Quality of life was assessed by a 36-item Short-form Health Survey (SF-36). Analyses were performed using a continuous or dichotomous (cut-off: 30 years) age-of-onset indicator. Results: Early-onset MDD (EOD, <30 years) was associated with longer illness (P = 0.003), unmarried status (P < 0.001), higher neuroticism (P ≤ 0.002) based on the SCL-90-R, and more limited social function and mental health (P = 0.006, P = 0.007) based on the SF-36 and SDS. The impairment of social function and clinical severity were more prominent at in-patients with younger onset ages. Special clinical features and more impaired social function and quality of life were associated with EOD, as in western studies. Conclusions: EOD often follows higher levels of neuroticism. Age of onset of MDD may be a predictor of clinical features and impaired social function, allowing earlier diagnosis and treatment. PMID:25758278

The aim of this study was to evaluate the association between baseline body mass index (BMI) and treatment outcome after a brief interdisciplinary fibromyalgia treatment program. Subjects (n = 477) with fibromyalgia participated in the fibromyalgia treatment program. They completed the Fibromyalgia Impact Questionnaire (FIQ) and the Short Form-36 Health Status Questionnaire (SF-36) at baseline and 6 to 12 mos after the fibromyalgia treatment program. Posttreatment changes in FIQ and SF-36 scores were compared after stratifying participants into four BMI groups: nonobese, overweight, moderately obese, and severely obese. All BMI groups achieved significant improvement in the FIQ total score; the FIQ subscales feel good, pain, fatigue, and morning tiredness; and the SF-36 subscales pain index, vitality, social functioning, and mental health index. Posttreatment changes in mean scores for each subscale generally did not differ significantly across BMI groups after adjusting for age and baseline scores. However, the SF-36 subscale scores of physical functioning and role-emotional were significantly less improved in the severely obese compared with the nonobese. Baseline BMI did not affect response to the fibromyalgia treatment program, as measured by the FIQ total score or SF-36 physical and mental component summary scores. However, the severely obese group showed less improvement compared with the nonobese group in the SF-36 physical functioning and role-emotional subscales.

Social outcomes and quality of life (QOL) of childhood cancer survivors (CCSs) remain unknown in Japan. We investigated these outcomes in young adult CCSs compared to those of their siblings in Japan, and analyzed the association between social outcome and SF-36 health survey subscale scores. Between 2007 and 2009, we performed a cross-sectional survey using self-rating questionnaires. We estimated social outcomes and health-related QOL by performing the SF-36 in each group: CCSs with or without stem cell transplantation (SCT)/radiotherapy (RT) and their siblings. Adjusted odds ratios for outcomes of interest were estimated using logistic regression analysis. Questionnaires from 185 CCSs and 72 CCS's siblings were analyzed. There were no differences in educational attainment or annual income. The SF-36 subscale scores of CCSs with SCT and RT were significantly lower than those of siblings in physical functioning (PF) (p < 0.001 and 0.003, respectively) and general health (GH) (both p = 0.001). Lower PF scores correlated with recurrence (p = 0.041) and late effects (p = 0.010), and poor GH scores with late effects (p = 0.006). The CCSs had made efforts to attain educational/vocational goals; however, a significant proportion of CCSs who had experienced late effects remain at increased risk of experiencing diminished QOL.

Patients with hyperventilation syndrome (HVS) report severe symptom-related suffering and often complain from insufficient medical attention. However, quality of life data in this context are scarce. We aimed at assessing the health-related quality of life (HRQoL) of HVS patients. Twenty-one HVS patients with extensive cardiorespiratory workup including cardiopulmonary exercise testing (CPET) filled in the generic SF-36 questionnaire and the results were compared to French normal values. Correlations between SF36 dimensions and clinical and functional data were established. All SF-36 scores were markedly decreased in HVS patients compared to healthy subjects: Physical Functioning: 44 ± 24, Social Functioning: 57 ± 27, Role Physical: 21 ± 32, Role Emotional: 48 ± 42, Mental Health: 51 ± 27, Vitality: 34 ± 20, Body Pain: 41 ± 21, General Health: 42 ± 21. These figures were all significantly lower in the HVS patients respective to the normal reference population. They were also lower than corresponding values published in patients with asthma or chronic obstructive pulmonary disease (COPD). "Vitality" and "Physical Functioning" scores were correlated with Nijmegen score (r = -0.594, p = 0.047) and peak respiratory frequency during CPET (r = -0.644, p = 0.019). The SF-36 Social Functioning score was correlated with the ventilatory threshold (r = 0.629, p = 0.034), peak V'E/V'CO2 (ventilation/CO2 production) (r = 0.650, p = 0.016) and peak PaCO2 (r = -0.664, p = 0.027). In conclusion, this study shows that HRQoL can be severely impaired in patients with HVS, which is one more reason to take this condition seriously. Copyright © 2013 Elsevier Ltd.

Older people at risk of social isolation (n = 393) completed the EQ-5D and the SF-12. Multiple regression analyses were performed to examine the relationship between levels of social isolation and health status/HRQL, controlling for demographic/clinical characteristics. The agreement between EQ-5D and SF-6D (SF-12) scores was explored using descriptive psychometric techniques. Health status and health state values were much lower than UK general population age-matched norms. After controlling for depression, physical co-morbidities, age, gender, living alone status, employment and accommodation, social isolation was significantly associated, to a degree that was clinically relevant, with EQ-5D DSI, SF-6D (SF-12) and SF-12 MCS scores. The potential for ceiling effects on the EQ-5D with this population was identified. This work highlights the burden that social isolation may have on the health and well-being of older people. The potential HRQL gains from addressing social isolation may be considerable, with those at risk of social isolation also a key target group.

Alzheimer's disease has a destructive drawbacks on the patient and his/her entire family as this disease badly af fects the behavior, cognition and abilities to do activities of daily living (ADL). The physical and mental benefits of exercise are widely known but seldom available to persons suffering from Alzheimer's disease. The aim of this study was to measure quality of life, systemic inflammation and psychological well-being response to aerobic exercises in Alzheimer's. Forty Alzheimer elderly subjects were enrolled in two groups; the first group received treadmill aerobic exercise, while the second group was considered as a control group and received no training intervention for two months. Assessment of tumor necrosis factor-alpha (TNF-α), interleukin-6 (IL-6), Rosenberg Self-Esteem Scale (RSES),Beck Depression Inventory (BDI), Profile of Mood States(POMS) and SF-36 health quality of life (SF-36 HRQL) were taken before and at the end of the study. There was a 25.2%, 19.4%, 23.5%, 21.3%, 17.7% , 11.7%, 12.5% and 10.1 % reduction in mean values of TNF-α, IL-6, BDI, POMS, health transition SF-36 subscale, bodily pain SF-36 subscale, role functioning: emotional SF-36 subscale and mental health SF-36 subscale respectively in addition to 15.7%, 13.1%, 12.6%, 11.1%, 13.2% and 11.2 % increase in mean values of RSES, physical functioning SF-36 subscale, role functioning:physical SF-36 subscale, general health SF-36 subscale, Vitality SF-36 subscale and Social functioning SF-36 subscale respectively in group (A) received aerobic exercise training, so that there was a significant reduction in the mean values of TNF-α, IL-6, BDI & POMS and increase in the mean values of SF-36 HRQL subscale scores, RSES in group (A) as a result of aerobic exercise training, while the results of group (B) who received no training intervention were not significant. Also, there were significant differences between mean levels of the investigated parameters in group (A) and group (B) at the end of the study (P<0.05). Treadmill walking exercise training is an effective treatment policy to improve quality of life, systemic inflammation and psychological wellbeing in Alzheimer's.

The study aimed to examine the relationship between environmental barriers and social participation among individuals with spinal cord injury (SCI). Individuals admitted to regional centers of the Model Spinal Cord Injury System in the United States due to traumatic SCI were interviewed and included in the National Spinal Cord Injury Database. This cross-sectional study applied a secondary analysis with a mixed effect model on the data from 3,162 individuals who received interviews from 2000 through 2005. Five dimensions of environmental barriers were estimated using the short form of the Craig Hospital Inventory of Environmental Factors-Short Form (CHIEF-SF). Social participation was measured with the short form of the Craig Handicap Assessment and Reporting Technique-Short Form (CHART-SF) and their employment status. Subscales of environmental barriers were negatively associated with the social participation measures. Each 1 point increase in CHIEF-SF total score (indicated greater environmental barriers) was associated with a 0.82 point reduction in CHART-SF total score (95% CI: -1.07, -0.57) (decreased social participation) and 4% reduction in the odds of being employed. Among the 5 CHIEF-SF dimensions, assistance barriers exhibited the strongest negative association with CHART-SF social participation score when compared to other dimensions, while work/school dimension demonstrated the weakest association with CHART-SF. Environmental barriers are negatively associated with social participation in the SCI population. Working toward eliminating environmental barriers, especially assistance/service barriers, may help enhance social participation for people with SCI.

To assess the quality of life among children and adolescents with thalassemia major. This cross-sectional study used the Pediatric Quality of Life Inventory (PedsQL). Children and adolescents with beta-thalassemia major who attended the Day Care Unit at King Abdulaziz University Hospital, Jeddah, Saudi Arabia from October 2012 to February 2013 were surveyed. The questions highlighted 4 health status scales, namely physical functioning (PF), emotional functioning (EF), school performance (SC), and social functioning (SF). Scores were calculated for each patient and data were analyzed using the Statistical Package for Social Sciences. We recruited 46 children (60.9% males). The median age of the sample was 12 years (range, 2-18 years). Most patients (84.8%) had 3 weekly blood transfusions. The mean+/-SD physical functioning (PF) score was 57.2+/-25.9; the EF score was 74.1+/-20.3, SF score was 78.5+/-24, and SC score was 54.3+/-24.2. The PF score was significantly lower in patients with a family history of thalassemia (p=0.003), and in those whose families had low incomes (p=0.049). Conversely, the SF score was significantly higher in school-educated patients (p=0.01). The quality of life of thalassemic children is affected by multiple factors, such as family income and a family history of thalassemia. Education appeared to increase patient functionality. Supportive measures could improve the quality of life in thalassemic patients.

To compare health-related quality of life (HRQoL) in children with prune-belly syndrome (PBS) and their caregivers to healthy controls, as children and adolescents with PBS face numerous potential physical and psychosocial challenges. Study participants completed the Pediatric Quality of Life Inventory Generic Core Scales (PedsQL) 4.0 generic core scales (children) or Quality of Life Enjoyment and Satisfaction Questionnaire Short Form (Q-LES-Q-SF) (caregivers) in an online, anonymous format. The PedsQL 4.0 is a 23-item, age-adjusted, validated questionnaire that assesses physical, emotional, social, and school functioning in pediatric patients. The Q-LES-Q-SF is a validated, self-report measure that assesses various areas of daily functioning in adults. PedsQL 4.0 was completed by 32 children with PBS. Individual physical (66.3 ± 20 vs 84.4 ± 17.3; P < .0001), emotional (68.4 ± 23.4 vs 80.9 ± 19.6; P < .01), social (63.1 ± 21.3 vs 87.4 ± 17.2; P  <  .0001), and school (53 ± 21.7 vs 78.6 ± 20.5; P < .0001) functioning scales were all significantly lower than in healthy children. Nineteen caregivers completed the Q-LES-Q-SF. Caregivers had a mean raw score of 54.8 ± 9.6, which was significantly lower (P  =  .02) than the comparative healthy adult cohort (59.8 ± 11.3). PBS profoundly impacts HRQoL in children, negatively affecting physical, emotional, social, and school functioning. Caregivers of PBS patients also report an overall lower quality of life, highlighting the challenges that families with chronically ill children often face. Copyright © 2015 Elsevier Inc.

Patient-reported outcomes like health-related quality of life (HRQL) have become increasingly important for full assessment of patients with chronic liver diseases (CLD). To explore the relative impact of different types of liver disease on HRQL as well as predictors of HRQL domains in CLD. Our HRQL databases with Short-Form 36 (SF-36) data were used. Scores for each of SF-36 scales (PF - physical functioning, RP - role functioning, BP - bodily pain, GH - general health, VT - vitality, SF - social functioning, RE - role emotional and MH - mental health, MCS - mental component score, PCS - physical component score) were compared between different types of CLD as well as other variables. Complete data were available for 1103 CLD patients. Demographic and clinical data included: age 54.2 +/- 12.0 years, 40% female, 761 (69%) with cirrhosis. Analysis revealed that age correlated significantly (P < 0.05) with worsening HRQL on every scale of the SF-36. Female patients had more HRQL impairments in PF, RP, BP, GH, VT and MH scales of SF-36 (Delta scale score: 6.6-10.7, P < 0.05). Furthermore, cirrhotic patients had more impairment of HRQL in every scale of SF-36 (Delta scale score: 6.6-43.0, P < 0.05). In terms of diagnostic groups, non-alcoholic fatty liver disease patients showed more impairment of HRQL. Analysis of this large CLD cohort suggests that a number of important clinicodemographic factors are associated with HRQL impairment. These findings contribute to the full understanding of the total impact of CLD on patients' health.

Abstract Introduction: Positive mental health is increasingly recognized as an important focus for public health policies and programs. In Canada, the Mental Health Continuum— Short Form (MHC-SF) was identified as a promising measure to include on population surveys to measure positive mental health. It proposes to measure a three-factor model of positive mental health including emotional, social and psychological well-being. The purpose of this study was to examine whether the MHC-SF is an adequate measure of positive mental health for Canadian adults. Methods: We conducted confirmatory factor analysis (CFA) using data from the 2012 Canadian Community Health Survey (CCHS)—Mental Health Component (CCHS-MH), and cross-validated the model using data from the CCHS 2011–2012 annual cycle. We examined criterion-related validity through correlations of MHC-SF subscale scores with positively and negatively associated concepts (e.g. life satisfaction and psychological distress, respectively). Results: We confirmed the validity of the three-factor model of emotional, social and psychological well-being through CFA on two independent samples, once four correlated errors between items on the social well-being scale were added. We observed significant correlations in the anticipated direction between emotional, psychological and social well-being scores and related concepts. Cronbach’s alpha for both emotional and psychological well-being subscales was 0.82; for social well-being it was 0.77. Conclusion: Our study suggests that the MHC-SF measures a three-factor model of positive mental health in the Canadian population. However, caution is warranted when using the social well-being scale, which did not function as well as the other factors, as evidenced by the need to add several correlated error terms to obtain adequate model fit, a higher level of missing data on these questions and weaker correlations with related constructs. Social well-being is important in a comprehensive measure of positive mental health, and further research is recommended. PMID:28402801

Allergic rhinitis, asthma or the atopic eczema/dermatitis syndrome (AEDS) may independently impair quality of life in patients. However, although many allergic patients may suffer from more than one disorder, the effect of concomitant disease -- in particular, the impact of AEDS -- is largely unknown. As part of a large multicenter clinical trial on the efficacy of mattress casings in house-dust mite (HDM) allergy, generic quality of life in a mixed population of 224 subjects with rhinitis (n = 198) and/or asthma (n = 111) and/or AEDS (n = 64) was studied. The study aimed to estimate quality of life impairment in these atopic patients and to address the question/issue of whether one atopic disorder goes beyond other existing allergic diseases, thereby causing further impairment to quality of life. Generic quality of life was assessed by SF-36. Quality of life in the atopic group was compared with a Dutch norm population. Multiple linear regression was used to determine the effects of disease (i.e. the presence of allergic rhinitis, asthma or AEDS) or disease severity, as assessed by visual analog scores (VAS) for asthma, rhinitis, VAS sleeplessness and VAS itching being considered as major symptoms in AEDS on SF-36 domains. Compared to the norm group, atopic patients were impaired in: physical functioning; role physical functioning; general health; vitality; and social functioning. The diagnosis of asthma was negatively associated with the SF-36 subscales for physical functioning (P = 0.02), and general health (P < 0.01). In line with these findings, asthma severity (VAS asthma) was negatively associated with physical functioning (P < 0.01), role physical functioning (P < 0.01), general health (P < 0.0.1), social functioning (P = 0.01), emotional functioning (P = 0.01), and vitality (P = 0.01). VAS sleeplessness had significant negative effect on role physical functioning (P < 0.01), bodily pain (P < 0.01), General health (P = 0.01), mental health (P < 0.01), social functioning (P < 0.01), and vitality (P < 0.01). In contrast, neither the diagnosis of allergic rhinitis or AEDS, nor VAS itching as an outcome parameter of AEDS, exerted additional effects on the SF-36 domains. Patients with atopic disease based on HDM allergy may have impaired quality of life. The majority of these patients have allergic rhinitis. The (co)existence of asthma, expressed in terms of diagnostic criteria or symptom severity, or the presence of sleep disorders as a consequence of AEDS, may further impair quality of life.

To translate, validate and assess the reliability of kidney disease quality of life - short form (KDQOL-SF-36) in Urdu, national language of Pakistan. Amulticentric descriptive cross-sectional study. Department of Nephrology, Mayo Hospital, Lahore, from February to July 2015. Patients of end-stage renal disease (ESRD) on maintenance hemodialysis (MHD) for more than three months, were included in the study. Patients of ESRD not on dialysis, and those with acute renal failure were excluded. The English version of KDQOL-SF-36 was translated in Urdu and then translated back in English; further validation was done by a senior professor of Punjab University, Lahore. One hundred and thirty patients were included in the study. Fifty patients were from Mayo Hospital, 35 from Shalamar Hospital and 50 from Shaikh Zayed Hospital, Lahore. The internal consistency reliability coefficient for overall scale was 0.84. Twelve sub-scales (symptoms, effect of kidney disease, burden of kidney disease, cognitive function, quality of social interaction, sexual function, social support, physical functioning, role physical, pain, emotional well-being and role emotional) had more than 0.70 internal consistency reliability coefficient. Overall mean score of the domains i.e kidney disease component score (KDCS), physical component score (PCS), and mental component score (MCS) was 60.62 ±17.61, 43.12 ±19.54, and 49.27 ±14.52, respectively. Asignificant positive relationship was observed between KDCS and MCS domains, KDCS and PCS domains, PCS, and MCS domains. The Urdu version of KDQOL-SF-36 is a reliable and valid version to measure QOLin kidney disease patients on dialysis in Pakistan.

To document the changes in self-reported health-related quality of life and knee function in a cohort of young female athletes who have sustained a knee injury. Prospective cohort. An outpatient sports medicine clinic and university student health service. A convenience sample of 255 females (age = 17.4 ± 2.4 years) who injured their knee participating in sport or recreational activities. Injuries were categorized as anterior cruciate ligament tears, anterior knee pain, patellar instability, meniscus tear, collateral ligament sprain, and other. Knee function was assessed with the 2000 International Knee Documentation Committee (IKDC) knee survey. Health-related quality of life was assessed with the SF-12 version 2.0 (acute) survey (SF-12). Dependent variables included the paired differences in the 2000 IKDC and SF-12 subscales, and composite scores from preinjury to diagnosis. Paired differences were assessed with paired t tests (P < 0.05) reported as the mean ± SD. International Knee Documentation Committee scores at diagnosis were significantly lower than preinjury scores (P < 0.001). SF-12 scores were lower (P < 0.001) at diagnosis for each subscale (physical functioning, role physical, bodily pain, general health, vitality, social function, role emotional, and mental health) as well as the physical and mental composite scores. In addition to negatively affecting knee function, sport medicine providers should be aware that knee injuries can negatively impact the health-related quality of life in these athletes immediately after injury.

To investigate the quality-of-life (QoL) and social participation of patients with traumatic brain injury (TBI) living in the community in Japan. A mixed-methods study of 29 post-TBI patients and 12 family members was conducted. Objective scales were used to evaluate QoL (Short Form Health Survey SF-36), depression (Zung Self-rating Depression Scale) and psychosocial function (Sydney Psychosocial Reintegration Scale, 2 nd edition). Subjective views of changes in social functioning, participation and suitability of family support were obtained by a semi-structured interview. Participants were classified into 'change' and 'no-change' groups for social participation and between-group comparisons of QoL and determinant factors of QoL were evaluated. The SF-36 social role component was significantly associated with the suitability of family support, followed by their understanding. However, QoL was not significantly associated with changes in social participation. Social participation was particularly influenced by the absence of rehabilitation support for low-skill labourers and housewives, whether they lost their employment or not. Advances in rehabilitation services are required, particularly to meet the specific needs of housewives and low-skill labourers. Families should receive sufficient education and short- and long-term strategies for providing suitable support to patients and their families should be implemented.

Objectives The aim of this study was to test the psychological and behavioural patterns of stigma (self-esteem and social participation) and their relationship to self-stigma, patient activation for engaging in self-care and glycaemic control among patients with type 2 diabetes mellitus (T2DM). Design A cross-sectional study. Setting 2 tertiary-level hospitals and 2 secondary-level hospitals in Japan. Participants A consecutive sample of 209 outpatients with T2DM. Inclusion criteria were as follows: presence of T2DM, age 20–74 years, no diagnosis of dementia and/or psychosis, and no need for urgent medical procedures. Outcome measures Study measures included a self-administered questionnaire to assess the Rosenberg Self-Esteem Scale (SES), the 3 subscales of 36-question Short Form Health Survey (SF-36; Social Function, Role Physical, Role Emotional), Self-Stigma Scale and Patient Activation Measure (PAM-13). Glycated haemoglobin was obtained from same day blood work. In our previous qualitative study, we found that psychological and behavioural patterns of stigma varied according to patients' levels of illness-related self-esteem as well as attitudes towards social participation. For quantitative consistency, we used the SES scale to measure self-esteem and the SF-36 subscales to measure social participation. We then divided participants into 4 groups by exhibited psychological and behavioural patterns: group A (high SES/high SF-36), group B (high SES/low SF-36), group C (low SES/high SF-36) and group D (low SES/low SF-36). Results Using analysis of covariance after controlling for age and sex, there was a significant difference in self-stigma levels between the four groups (F[3203]=15.70, p<0.001). We observed the highest mean self-stigma levels in group D. Group D also had significantly lower PAM-13 scores than those of groups A (p<0.001) and B (p=0.02). Conclusions The psychological and behavioural pattern of group D was found to be associated with higher levels of self-stigma and poorer patient activation for self-care. PMID:28360238

The Short Form-8 (SF-8) questionnaire is a commonly used 8-item instrument of health-related quality of life (QOL) and provides a health profile of eight subdimensions. Our aim was to examine the psychometric properties of the Japanese version of the SF-8 instrument using methodology based on nominal categories model. Using data from an adjusted random sample from a nationally representative panel, the nominal categories modeling was applied to SF-8 items to characterize coverage of the latent trait (theta). Probabilities for response choices were described as functions on the latent trait. Information functions were generated based on the estimated item parameters. A total of 3344 participants (53%, women; median age, 35 years) provided responses. One factor was retained (eigenvalue, 4.65; variance proportion of 0.58) and used as theta. All item response category characteristic curves satisfied the monotonicity assumption in accurate order with corresponding ordinal responses. Four items (general health, bodily pain, vitality, and mental health) cover most of the spectrum of theta, while the other four items (physical function, role physical [role limitations because of physical health], social functioning, and role emotional [role limitations because of emotional problems] ) cover most of the negative range of theta. Information function for all items combined peaked at -0.7 of theta (information = 18.5) and decreased with increasing theta. The SF-8 instrument performs well among those with poor QOL across the continuum of the latent trait and thus can recognize more effectively persons with relatively poorer QOL than those with relatively better QOL.

As the number of survivors of Hodgkin's lymphoma (HL) increases, there has been a growing interest in long-term treatment-related side effects and their impact on the quality of life (QoL). The aim of this study was to assess the association of social network and social support with the QoL and fatigue among long-term HL survivors. A total of 200 HL survivors were included. The generic Short Form-12 (SF-12) questionnaire, the QoL cancer survivor's questionnaire (QOL-CS), and the Multidimensional Fatigue Inventory were used to assess QoL and fatigue. Social network and social support were evaluated with the Social Support Survey. Social network and all social support measures were favorably associated with two or more SF-12 scales, mainly with physical functioning and the mental health scales. Social network and social support dimensions were also associated with better QOL-CS scores. Affective support, informational support, positive interaction, and emotional support were associated with less fatigue. Both social network and social support are associated with better QoL and lower levels of fatigue in HL survivors. This information may be useful to health professionals and community organizations in implementing effective interventions to improve these patients' quality of life.

The aim of this study was to assess whether outcomes from excision of acoustic neuroma vary among patients and have a material impact on their quality of life (QOL). A questionnaire concerning postoperative symptoms and the Short Form 36 (SF-36) QOL instrument were mailed to 97 consecutive patients who had undergone acoustic neuroma surgery via the translabyrinthine approach. The survey response rate was 78% and the symptomatology was consistent with other reports, supporting the representativeness of the sample. The respondents' QOL was rated significantly below published norms and their work capacity was reportedly reduced. Specifically, the following SF-36 dimensions were reduced: physical functioning and role-physical, together with vitality, general health, and social functioning. Greater numbers of postoperative symptoms and larger tumors were associated with a worse rating of physical functioning. More severe balance problems were associated with lower ratings of social functioning. The disparity between the patient's self-estimate and self-measurement and the clinician's assessment of the patient's facial functioning raises doubts about the validity of subjective reports and assessment. The present study supports the use of generic QOL measures to assess outcome and to draw comparisons between different populations.

In a 9-month prospective cohort multicentre study, patients with gout self-reported race, dichotomized as Caucasian or African American (others excluded). We calculated HRQOL/function scores adjusted for age, study site and college education for Short Form-36 (SF-36; generic HRQOL), Gout Impact Scale (GIS; disease-specific HRQOL) and HAQ-disability index (HAQ-DI; functional ability). Longitudinally adjusted scores were computed using multivariable mixed-effect regression models with a random patient effect and fixed sequential visit effect (3-monthly visits). Results. Compared with Caucasians (n = 107), African Americans (n = 60) with gout were younger (61.1 vs 67.3 years) and had higher median baseline serum urate (9.0 vs 7.9 mg/dl) (P < 0.01). African Americans with gout had worse HRQOL scores on three SF-36 domains, the mental component summary (MCS) and two of the five GIS scales than Caucasians [mean (s.e.); P ⩽ 0.02 for all]: SF-36 mental health, 39.7 (1.1) vs 45.2 (0.9); SF-36 role emotional, 42.1 (4.2) vs 51.4 (4.2); SF-36 social functioning, 36.0 (1.1) vs 40.0 (0.9) (P = 0.04); SF-36 MCS, 43.2 (3.1) vs 50.0 (3.2); GIS unmet treatment need, 37.6 (1.6) vs 31.5 (1.4); and GIS concern during attacks, 53.3 (3.7) vs 47.4 (3.7). Differences between the respective HAQ-DI total scores were not statistically significant; 0.98 (0.1) vs 0.80 (1.0) (P = 0.11). Racial differences in SF-36 mental health, role emotional and MCS scales exceeded, and for HAQ-DI approached, the minimal clinically important difference thresholds. Conclusions. African Americans with gout have significantly worse HRQOL compared with Caucasians. Further research is necessary in the form of studies targeted at African Americans on how best to improve these outcomes. PMID:28028159

Purpose Prior research has shown a significant relationship between six minute walking distances (6MWD) and health related quality of life (HRQL) in patients with chronic obstructive pulmonary disease (COPD). However, few have examined this relationship above and below the 350 meters (m) threshold that prognosticates survival. We further investigated whether serum biomarkers could provide insight into the causes of quality of life differences above and below this threshold. Methods Measures of lung function, 6MWD, HRQL (SGRQ and SF-36) were compared in patients with COPD. Differences in HRQL domains and serum biomarkers were compared in patients whose 6MWD were > or < 350m. Results In patients walking <350m, scores in the physical domains of the SF-36 and SGRQ were significantly different than their counterparts with greater 6MWD. However, there was no association between any biomarkers and the physical domains of the SF-36 and the SGRQ. In patients walking <350m, only the Il-8 levels were associated with lower scores in SF-36 domains of emotional role, pain, vitality and mental health (average r=−0.702, p=0.01). In contrast, in patients walking >350m, surfactant protein D (SP-D) levels were associated with higher SF-36 scores in general pain, vitality and social functioning (average r = 0.42, p=0.04). Conclusions In COPD, there is an association between 6MWD and the physical domains of the SF-36 and SGRQ in those patients walking < 350m. The physical differences between patients walking less or more than 350m are not related to systemic inflammation. The association between IL-8 with nonphysical domains in patients with 6MWD < 350m suggests that inflammation may play a larger role in the perceptive domain than previously recognized.

To examine the associations of mental health functioning (SF-36) and work and family related psychosocial factors with intentions to retire early. Cross sectional survey data (n = 5037) from the Helsinki Health Study occupational cohort in 2001 and 2002 were used. Intentions to retire early were inquired with a question: "Have you considered retiring before normal retirement age?" Mental health functioning was measured by the Short Form 36 (SF-36) mental component summary (MCS). Work and family related psychosocial factors included job demands and job control, procedural and relational justice, conflicts between work and family, and social network size. Multinomial regression models were used to analyse the data. Poor mental health functioning, unfavourable psychosocial working conditions, and conflicts between work and family were individually related to intentions to retire early. After adjustments for all work and family related factors the odds ratio for low mental health functioning was halved (from OR = 6.05 to 3.67), but nevertheless the association between poor mental health functioning and strong intentions to retire early remained strong. These findings highlight not only the importance of low mental health and unfavourable working conditions but also the simultaneous impact of conflicts between work and family to employees' intentions to retire early.

To develop and test functions for predicting the preference-based SF-6D index scores from the SF-8 health survey. This study was a secondary analysis of data collected in a population health survey in which respondents (n = 7,529) completed both the SF-36 and the SF-8 questionnaires. We examined seven ordinary least-square estimators for their performance in predicting SF-6D scores from the SF-8 at both the individual and the group levels. In general, all functions performed similarly well in predicting SF-6D scores, and the predictions at the group level were better than predictions at the individual level. At the individual level, 42.5-51.5% of prediction errors were smaller than the minimally important difference (MID) of the SF-6D scores, depending on the function specifications, while almost all prediction errors of the tested functions were smaller than the MID of SF-6D at the group level. At both individual and group levels, the tested functions predicted lower than actual scores at the higher end of the SF-6D scale. Our study developed functions to generate preference-based SF-6D index scores from the SF-8 health survey, the first of its kind. Further research is needed to evaluate the performance and validity of the prediction functions.

Narcolepsy patients report lower health-related quality of life (HRQoL) than the general population, as measured by the Short Form-36 Health Survey (SF-36). This analysis evaluated whether changes in SF-36 correlated with physician-rated Clinical Global Impression of Change (CGI-C). Data were from 209 of 228 narcolepsy patients participating in an 8-week clinical trial of sodium oxybate. Changes from baseline for SF-36 subscales (Physical Functioning, Role Physical, Bodily Pain, General Health, Vitality, Social Functioning, Role Emotional, and Mental Health) and the summary scores were evaluated for correlation with CGI-C overall and by treatment group. Correlations were calculated using the Pearson product-moment correlation coefficient (r). Correlations described an inverse relationship in scores, but a direct relationship in improvement; lower CGI-C scores (i.e., better) were associated with higher SF-36 subscale scores (i.e., improved HRQoL). Moderate and significant correlations were observed for Vitality (r = -0.464; P < 0.0001) and Role Physical (r = -0.310; P < 0.0001) subscales, but weak correlations were observed with other subscales including summary scores. Correlations were stronger at higher sodium oxybate doses for most SF-36 subscales. Some aspects of HRQoL, measured by the SF-36, may be associated with narcolepsy. In particular, Vitality (indicative of energy and tiredness) and Role Physical (impact of physical function on daily roles) moderately correlated with overall change in status observed by clinicians. However, lack of strong correlations between SF-36 and CGI-C indicates differences in patient and clinician perspectives of disease, and suggest a need for broader assessment of the impact of narcolepsy and its treatment on patients.

To evaluate the effectiveness of magnetotherapy in the treatment of hand osteoarthritis (HO). In this randomized controlled single-blind follow-up study, patients with HO were randomly assigned into 2 groups (G1 and G2). The subjects in G1 (n=25) received 25Hz, 450 pulse/s, 5-80G, magnetotherapy of totally 10 days and 20 min/day combined with active range of motion/strengthening exercises for the hand. G2 (n=25) received sham-magnetotherapy for 20 min/day for the same duration combined with the same hand exercises. Outcome measures were pain and joint stiffness evaluation, handgrip and pinchgrip strength (HPS), Duruöz and Auscan Hand Osteoarthritis Indexes (DAOI) and Short Form-36 Health Questionnaire (SF-36) administered at baseline, immediately after treatment and at the follow up. When the groups were compared with each other, improvement observed in SF-36 Pain (p<0.001), SF-36 Social Function (p=0.030), SF-36 Vitality (p=0.002), SF-36 General Health (p=0.001), Pain at rest (p<0.001), Pain at motion (p<0.001), Joint stiffness (p<0.001), DAOI (p<0.001) were in favor of G1. Changes in pain, function and quality of life scores showed significant advantage in favor of the applied electromagnetic intervention in patients with HO. Copyright © 2013 Elsevier Ltd.

To evaluate and compare the effectiveness of a 16-week multidisciplinary (exercise plus psychological therapy) and biodanza intervention in women with fibromyalgia. Thirty-eight women with fibromyalgia were distributed to a 16-week multidisciplinary (3-times/week) intervention (n=21) or Biodanza (1-time/week) intervention (n=17). We assessed tender point, body composition, physical fitness and psychological outcomes (Fibromyalgia Impact Questionnaire, the Short-Form Health Survey 36 questionnaire (SF-36), the Hospital Anxiety and Depression Scale, Vanderbilt Pain Management Inventory (VPMI), Rosenberg Self-Esteem Scale and General Self-Efficacy Scale). We observed a significant group*time interaction effect for the scales of SF-36 physical role (P=0.038) and social functioning (P=0.030) and for the passive coping scale in VPMI (P=0.043). Post hoc analysis revealed a significant improvement on social functioning (P=0.030) in the multidisciplinary group whereas it did not change in the Biodanza group. Post hoc analysis revealed a reduction in the use of passive coping (positive) (P less than 0.001) in the multidisciplinary group. There was no significant interaction or time effect in body composition and physical fitness. 16 weeks of multidisciplinary intervention induced greater benefits than a Biodanza intervention for social functioning and the use of passive coping strategies in women with fibromyalgia.

Patients with severe chronic obstructive pulmonary disease (COPD) have impaired quality of life, but the relationship between their nutritional status and quality of life has not been established. The aim of this study was to determine the relationship between quality of life and nutritional status in hospitalized COPD patients. Demographic data, quality of life and nutritional status of 90 inpatients with a mean age of 68.76 ± 10.85 years were enrolled in the study. The Nutritional Risk Screening 2002 (NRS-2002) tool was used to evaluate their nutritional status. The quality of life was assessed using the Short Form-36 (SF-36) questionnaire. The correlation analysis was used for the relationship between SF-36 subscales and nutritional status variables. Of the 90 COPD patients included in the study, 54.4 % were men, and 45.6 % were women. Moderate, severe, and very severe COPD were detected in 37.8 %, 38.9 %, and 23.3 % of the patients, respectively. At risk of malnutrition were 55.6 % of the 90 COPD patients, whereas 44.4 % were not. The scores for physical function, physical role functioning, pain, general health, emotional role functioning, vitality, social function, and mental function subscales were lower in the patients at risk of malnutrition (p <0.001). There was a statistically significant negative correlation between malnutrition score and the subscores of SF-36 related to physical function, physical role functioning, pain, general health, emotional role functioning, vitality, social function, and mental function (p <0.001). COPD patients were found to have a high risk of malnutrition that adversely affects their quality of life. Therefore, the evaluation of the nutritional status of COPD patients should be an integral part of their clinical treatment plans aiming towards improving their quality of life.

Integrative strategy of health services delivery has been proven to be effective in economically developed countries, where the healthcare systems have enough qualified primary care providers. However rural China lacks such providers to act as gatekeeper, besides, Chinese rural hypertensive patients are usually of old age, more likely to be exposed to health risk factors and they experience a greater socio-economic burden. All these Chinese rural setting specific features make the effectiveness of integrative strategy of health services in improving health related quality of life among Chinese rural hypertensive patients uncertain. In order to assess the impact of integrative strategy of health services delivery on health related quality of life among Chinese rural hypertensive patients, a two-year quasi-experimental trial was conducted in Chongqing, China. At baseline the sample enrolled 1006 hypertensive patients into intervention group and 420 hypertensive patients into control group. Physicians from village clinics, town hospitals and county hospitals worked collaboratively to deliver multidisciplinary health services for the intervention group, while physicians in the control group provided services without cooperation. The quality of life was studied by SF-36 Scale. Blood pressures were reported by town hospitals. The Difference-in-Differences model was used to estimate the differences in SF-36 score and blood pressure of both groups to assess the impact. The study showed that at baseline there was no statistical difference in SF-36 scores between both groups. While at follow-up the intervention group scored higher in overall SF-36, Role Physical, Body Pain, Social Functioning and Role Emotional than the control group. The Difference-in-Differences result demonstrated that there were statistical differences in SF-36 total score (p = 0.011), Role Physical (p = 0.027), Social Functioning (p = 0.000), Role Emotional (p = 0.002) between both groups. Integrative services delivery improved the score of SF-36 by 4.591 ± 1.794, and also improved the score in domains of Role Physical, Social Functioning and Role Emotional by 8.289 ± 3.753, 9.762 ± 2.019 and 12.534 ± 4.083, respectively. Patients in the intervention group obtained lower systolic blood pressure and diastolic blood pressure. Integrative strategy of health services delivery improved health related quality of life and blood pressure control among rural Chinese hypertensive patients.

The reliability, validity, and feasibility of the routine use of a generic health status instrument, the Short-Form-36 Health Survey (SF-36), were examined in a psychiatric outpatient clinic of a general hospital. The sample comprised 411 patients referred to an outpatient psychiatry department between April 1994 and March 1995. They filled out the SF-36 along with their admission forms. Scores and reports were generated, and the results were returned to the charts and used at weekly clinical conference discussions. Feasibility was evaluated using subjective and objective data on administration of the instrument, its psychometric properties, and costs. Results from the outpatient psychiatry patients were compared with those from patients scheduled for elective surgery and a healthy normative sample. Routine administration of the SF-36 was successfully achieved with minimal resistance from staff and patients. The SF-36 provided reliable and valid data. As predicted, patients with emotional disorders scored lower, indicating more impairment, on scales measuring mental health than did the elective surgery patients and the normative sample. However, the psychiatric patients' scores on the physical health scale were lower than clinicians expected. Compared with the elective surgery patients, the psychiatric patients were less impaired on only the physical functioning and bodily pain scales; no difference was found between the two groups in role functioning due to physical problems. Routine use of the SF-36 in a general hospital psychiatric outpatient clinic was feasible, and the results were reliable, valid, and helpful to clinicians. Psychiatric patients' significantly lower scores in physical health and social and role functioning provided additional information about their difficulties.

There is growing interest in health related quality of life (HRQoL) as an outcome measure in international trials. However, there might be differences in the conceptualization of HRQoL across different socio-cultural groups. The objectives of current study were: (I) to compare HRQoL, measured with the short form (SF)-36 of Dutch and Chinese traumatic brain injury (TBI) patients 1 year after injury and; (II) to assess whether differences in SF-36 profiles could be explained by cultural differences in HRQoL conceptualization. TBI patients are of particular interest because this is an important cause of diverse impairments and disabilities in functional, physical, emotional, cognitive, and social domains that may drastically reduce HRQoL. A prospective cohort study on adult TBI patients in the Netherlands (RUBICS) and a retrospective cohort study in China were used to compare HRQoL 1 year post-injury. Differences on subscales were assessed with the Mann-Whitney U-test. The internal consistency, interscale correlations, item-internal consistency and item-discriminate validity of Dutch and Chinese SF-36 profiles were examined. Confirmatory factor analysis was performed to assess whether Dutch and Chinese data fitted the SF-36 two factor-model (physical and mental construct). Four hundred forty seven Dutch and 173 Chinese TBI patients were included. Dutch patients obtained significantly higher scores on role limitations due to emotional problems (p < .001) and general health (p < .001), while Chinese patients obtained significantly higher scores on physical functioning (p < .001) and bodily pain (p = .001). Scores on these subscales were not explained by cultural differences in conceptualization, since item- and scale statistics were all sufficient. However, differences among Dutch and Chinese patients were found in the conceptualization of the domains vitality, mental health and social functioning. One year after TBI, Dutch and Chinese patients reported a different pattern of HRQoL. Further, there might be cultural differences in the conceptualization of some of the SF-36 subscales, which has implications for outcome evaluation in multi-national trials.

Students seeking degrees in healthcare in Ecuador participate in community improvement projects and provide free health services under the supervision of faculty health professionals. The aim of this study is to determine the impact of a community-based intervention delivered by nursing students on health-related quality of life (HRQoL) and perceived social support of a rural population in Ecuador. A quasi-experimental non-equivalent control group design study was conducted in two rural communities in Tumbaco, Ecuador. Families from one rural community were invited to participate in the intervention, receiving 8 weekly home visits from nursing students. Families from a neighboring community were similarly recruited as wait-list controls. One member of each family was consented into the study; the final sample included 43 intervention participants and 55 control participants. HRQoL and perceived social support were assessed before and after the intervention in both groups. The SF-12 was used to measure HRQoL, including eight domain scores and two composite scores, and the Interpersonal Support Evaluation List was used as an indicator of perceived social support. Difference-in-differences (DD) analyses were conducted to mitigate the effects of any baseline differences in the non- equivalent control group design. When compared to the control group, the intervention group realized significant improvements in the physical component summary score of the SF-12 (4.20, p < 0.05) and the physical function domain of the SF-12 (4.92, p < 0.05). There were no statistically significant differences for any other components of the SF-12 or in the measure of perceived social support. Nursing students completing their rural service rotation have the potential to improve the health-related quality of life of rural residents in Ecuador. Future research should continue to examine the impact of service-based learning on recipient populations.

The aim of this study was to test the psychological and behavioural patterns of stigma (self-esteem and social participation) and their relationship to self-stigma, patient activation for engaging in self-care and glycaemic control among patients with type 2 diabetes mellitus (T2DM). A cross-sectional study. 2 tertiary-level hospitals and 2 secondary-level hospitals in Japan. A consecutive sample of 209 outpatients with T2DM. Inclusion criteria were as follows: presence of T2DM, age 20-74 years, no diagnosis of dementia and/or psychosis, and no need for urgent medical procedures. Study measures included a self-administered questionnaire to assess the Rosenberg Self-Esteem Scale (SES), the 3 subscales of 36-question Short Form Health Survey (SF-36; Social Function, Role Physical, Role Emotional), Self-Stigma Scale and Patient Activation Measure (PAM-13). Glycated haemoglobin was obtained from same day blood work. In our previous qualitative study, we found that psychological and behavioural patterns of stigma varied according to patients' levels of illness-related self-esteem as well as attitudes towards social participation. For quantitative consistency, we used the SES scale to measure self-esteem and the SF-36 subscales to measure social participation. We then divided participants into 4 groups by exhibited psychological and behavioural patterns: group A (high SES/high SF-36), group B (high SES/low SF-36), group C (low SES/high SF-36) and group D (low SES/low SF-36). Using analysis of covariance after controlling for age and sex, there was a significant difference in self-stigma levels between the four groups (F[3203]=15.70, p<0.001). We observed the highest mean self-stigma levels in group D. Group D also had significantly lower PAM-13 scores than those of groups A (p<0.001) and B (p=0.02). The psychological and behavioural pattern of group D was found to be associated with higher levels of self-stigma and poorer patient activation for self-care.

The aim of this study is to report normative data for the Short-Form 36 version 2 (SF-36v2) for assessing health-related quality of life, in the Singapore general population. Data for English and Chinese-speaking participants of the Singapore Prospective Study Programme were analysed. The SF-36v2 scores were norm-based with the English-speaking Singapore general population as reference and reported by age (in decades), gender and ethnicity as well as for the 5 most prevalent chronic medical conditions. Scores were reported separately for the English and Chinese language versions. A total of 6151 English-speaking (61.5% Chinese and 19.2% Malay) and 1194 Chinese-speaking participants provided complete data. Mean (SD) age of all participants was 49.6 (12.58) years with 52.4% being women. In both languages, women reported lower scores than men on all scales. Among the chronic medical conditions, stroke had the largest impact on all English SF-36v2 scales and on 3 Chinese SF-36v2 scales (role-physical, general health and social functioning). We have provided detailed normative data for the Singapore English and Chinese SF-36v2, which would be valuable in furthering HRQoL research in Singapore and possibly the region.

To compare the health-related quality of life (HRQOL) and the functional ability by race in patients with gout. In a 9-month prospective cohort multicentre study, patients with gout self-reported race, dichotomized as Caucasian or African American (others excluded). We calculated HRQOL/function scores adjusted for age, study site and college education for Short Form-36 (SF-36; generic HRQOL), Gout Impact Scale (GIS; disease-specific HRQOL) and HAQ-disability index (HAQ-DI; functional ability). Longitudinally adjusted scores were computed using multivariable mixed-effect regression models with a random patient effect and fixed sequential visit effect (3-monthly visits). Compared with Caucasians (n = 107), African Americans (n = 60) with gout were younger (61.1 vs 67.3 years) and had higher median baseline serum urate (9.0 vs 7.9 mg/dl) (P < 0.01). African Americans with gout had worse HRQOL scores on three SF-36 domains, the mental component summary (MCS) and two of the five GIS scales than Caucasians [mean (se); P ⩽ 0.02 for all]: SF-36 mental health, 39.7 (1.1) vs 45.2 (0.9); SF-36 role emotional, 42.1 (4.2) vs 51.4 (4.2); SF-36 social functioning, 36.0 (1.1) vs 40.0 (0.9) (P = 0.04); SF-36 MCS, 43.2 (3.1) vs 50.0 (3.2); GIS unmet treatment need, 37.6 (1.6) vs 31.5 (1.4); and GIS concern during attacks, 53.3 (3.7) vs 47.4 (3.7). Differences between the respective HAQ-DI total scores were not statistically significant; 0.98 (0.1) vs 0.80 (1.0) (P = 0.11). Racial differences in SF-36 mental health, role emotional and MCS scales exceeded, and for HAQ-DI approached, the minimal clinically important difference thresholds. African Americans with gout have significantly worse HRQOL compared with Caucasians. Further research is necessary in the form of studies targeted at African Americans on how best to improve these outcomes.

Abstract Objective This individual patient data (IPD) meta‐analysis aimed to evaluate the effects of psychosocial interventions (PSI) on quality of life (QoL), emotional function (EF), and social function (SF) in patients with cancer, and to study moderator effects of demographic, clinical, personal, and intervention‐related characteristics. Methods Relevant studies were identified via literature searches in 4 databases. We pooled IPD from 22 (n = 4217) of 61 eligible randomized controlled trials. Linear mixed‐effect model analyses were used to study intervention effects on the post‐intervention values of QoL, EF, and SF (z‐scores), adjusting for baseline values, age, and cancer type. We studied moderator effects by testing interactions with the intervention for demographic, clinical, personal, and intervention‐related characteristics, and conducted subsequent stratified analyses for significant moderator variables.Results: PSI significantly improved QoL (β = 0.14,95%CI = 0.06;0.21), EF (β = 0.13,95%CI = 0.05;0.20), and SF (β = 0.10,95%CI = 0.03;0.18). Significant differences in effects of different types of PSI were found, with largest effects of psychotherapy. The effects of coping skills training were moderated by age, treatment type, and targeted interventions. Effects of psychotherapy on EF may be moderated by cancer type, but these analyses were based on 2 randomized controlled trials with small sample sizes of some cancer types. Conclusions PSI significantly improved QoL, EF, and SF, with small overall effects. However, the effects differed by several demographic, clinical, personal, and intervention‐related characteristics. Our study highlights the beneficial effects of coping skills training in patients treated with chemotherapy, the importance of targeted interventions, and the need of developing interventions tailored to the specific needs of elderly patients.

To examine ethnic differences in the relationship between depressive symptoms and specific aspects of heath-related quality of life in people with type 2 diabetes. Cross-sectional data from 190 people with type 2 diabetes of Native Hawaiian (50%), Filipino (16%), Japanese (18%), and mixed-ethnic (16%) ancestries from the rural community of North Kōhala, Hawai'i were examined in this study. Depressive symptoms were measured with the Center for Epidemiological Studies-Depression (CES-D) scale. Health-related quality of life was measured with the Short Form-36 Health Survey (SF-36). Eight health-related quality of life constructs were examined: Physical Functioning, Role-Physical Functioning, Role-Emotional Functioning, Social Functioning, Bodily Pain, Vitality, General Health, and Health Transition. Hierarchical regression analyses of the interaction between ethnicity and the SF-36 subscales of Physical Functioning, Role-Emotional Functioning, Bodily Pain, Vitality, and General Health indicated statistically significant associations with CES-D scores after controlling for sociodemographic factors, glycemic status, and social support. Ethnicity moderated the relationship between depressive symptoms and the health-related quality of life aspects of physical and role-emotional functioning, bodily pain, vitality, and general health perception in people with type 2 diabetes. This relationship was strongest for Filipinos followed by Native Hawaiians and people of mixed-ethnic ancestries.

The Mental Health Continuum-Short Form (MHC-SF) is a brief scale measuring positive human functioning. The study aimed to examine the factor structure and to explore the cross-cultural utility of the MHC-SF using bifactor models and exploratory structural equation modelling. Using multigroup confirmatory analysis (MGCFA) we examined the measurement invariance of the MHC-SF in 38 countries (university students, N = 8,066; 61.73% women, mean age 21.55 years). MGCFA supported the cross-cultural replicability of a bifactor structure and a metric level of invariance between student samples. The average proportion of variance explained by the general factor was high (ECV = .66), suggesting that the three aspects of mental health (emotional, social, and psychological well-being) can be treated as a single dimension of well-being. The metric level of invariance offers the possibility of comparing correlates and predictors of positive mental functioning across countries; however, the comparison of the levels of mental health across countries is not possible due to lack of scalar invariance. Our study has preliminary character and could serve as an initial assessment of the structure of the MHC-SF across different cultural settings. Further studies on general populations are required for extending our findings. © 2018 Wiley Periodicals, Inc.

The amygdala is a complex structure with distinct subregions and dissociable functional networks. The laterobasal subregion of the amygdala is hypothesized to mediate the presentation and severity of autism symptoms, although very little data are available regarding amygdala dysfunction at the subregional level. In this study, we investigated the relationship between abnormal amygdalar intrinsic connectivity, autism symptom severity, and anxiety and depressive symptoms. We collected resting state fMRI data on 31 high functioning adolescents and adults with autism spectrum disorder and 38 typically developing (TD) controls aged 14-45. Twenty-five participants with ASD and 28 TD participants were included in the final analyses. ASD participants were administered the Autism Diagnostic Interview-Revised and the Autism Diagnostic Observation Schedule. Adult participants were administered the Beck Depression Inventory II and the Beck Anxiety Inventory. Functional connectivity analyses were conducted from three amygdalar subregions: centromedial (CM), laterobasal (LB) and superficial (SF). In addition, correlations with the behavioral measures were tested in the adult participants. In general, the ASD group showed significantly decreased connectivity from the LB subregion and increased connectivity from the CM and SF subregions compared to the TD group. We found evidence that social symptoms are primarily associated with under-connectivity from the LB subregion whereas over-connectivity and under-connectivity from the CM, SF and LB subregions are related to co-morbid depression and anxiety in ASD, in brain regions that were distinct from those associated with social dysfunction, and in different patterns than were observed in mildly symptomatic TD participants. Our findings provide new evidence for functional subregional differences in amygdala pathophysiology in ASD.

Quality of life is one of the parameters to check the improvement of hemodialysis treatment among hemodialysed patients. Those patients will be dealing with this treatment in long term if this treatment is the only way for them to replace their kidney function and this thing will affect their quality of life. To evaluate the quality of life patients on hemodialysis using kidney disease quality of life-short term 24 (KDQoL-SF24) Malaysian Version. Cohort observational study was conducted in this study. The study included 78 hemodialysed patients in HD center Penang, Malaysia. There were 9 components which had the lower of the mean and standard deviation (SD) than the standard form; work status (15.01 ± 35.57), cognitive function (75.66 ± 13.75), quality of life social interaction (76.32 ± 16.11), sleep (55.86 ± 15.30), social support (59.61 ± 22.08), patient satisfaction (43.24 ± 15.32), physical functioning (50.06 ± 42.81), general health (29.62 ± 25.56), and role emotional (54.27 ± 49.92). In this HD center, the group of patient's age who had the lower mean ± SD from the KDQoL-SF Manual Standard were the first and the sixth groups of patient's age (≤20 and 61-70). The study conducted in HD center, Penang, Malaysia showed that the scoring of work status, cognitive function, quality of social interaction, sleep, social support, patient satisfaction, physical functioning, general health, and role emotional were low than standard form.

We aimed to evaluate the measurement properties of the Singapore English and Chinese versions of the Short-Form 36 version 2 (SF-36v2) Questionnaire, an improved version of the widely used SF-36, for assessing health-related quality of life (HRQoL) in a multi-ethnic urban Asian population in Singapore. SF-36v2 scores and data on medical history, demographic and lifestyle factors from the Singapore Prospective Study Programme were analyzed. Convergent and divergent validity, internal consistency, floor and ceiling effects, known group validity and factor structure of the SF-36v2 were assessed for the English and Chinese versions, respectively. Complete data for 4,917 participants (45.8 %) out of 10,747 eligible individuals were analyzed (survey language: 4,115 English and 802 Chinese). Item-scale correlations exceeded 0.4 for all items of the English SF-36v2 and for all except one item of the Chinese SF-36v2 (bathe and dress: item-scale correlation: 0.36). In the English SF-36v2, Cronbach's alpha exceeded 0.70 for all scales. In the Chinese SF-36v2, Cronbach's alpha exceeded 0.7 on all scales except social functioning (Cronbach's alpha: 0.68). For known groups validity, respondents with chronic medical conditions expectedly reported lower SF-36v2 score on most English and Chinese SF-36v2 scales. In confirmatory factor analysis, the Singapore three-component model was favored over the United States two-component and Japan three-component models. The English and Chinese SF-36v2 are valid and reliable for assessing HRQoL among English and Chinese-speaking Singaporeans. Test-retest reliability and responsiveness of the English and Chinese SF-36v2 in Singapore remain to be evaluated.

Spasmodic dysphonia (SD), a disabling focal dystonia involving the laryngeal musculature, is most commonly treated by the intramuscular injection of botulinum toxin (BTX). Although the treatment is well tolerated and generally produces clinical voice improvement, it has never been statistically shown to alter the patient's perception of voice quality or general health. Declining resources for medical care mandate that treatment outcomes be documented. A prospective analysis of the effects of BTX on the patient's perception of voice and general health was undertaken. The Voice Handicap Index (VHI) and Short Form 36 (SF-36) surveys were administered to patients before treatment and 1 month after. Pretreatment and posttreatment scores were analyzed with a Student's t-test. On the VHI, improvements in the patients' perception of their functional, physical, and emotional voice handicap reached statistical significance (p < or = .0005). On the SF-36, patients had statistically significant improvements in mental health (p < or = .03) and social functioning (p < or = .04). Treatment of SD with BTX significantly lessened the patients' perception of dysphonia. In addition, it improved their social functioning and their perception of their mental health. These outcome measures justify the continued treatment of SD with BTX.

According to Antonovsky's salutogenic concept, a strong sense of coherence is associated with physical and psychological health. The goal of this study was to analyze the association of Antonovsky's sense of coherence with physical and psychosocial health components in patients with hip and knee osteoarthritis before and after in- and outpatient rehabilitation. Prospective cohort study with 335 patients, 136 (41%) with hip and 199 (59%) with knee osteoarthritis. The outcome was measured by Short Form-36 (SF-36), Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) and the Sense of Coherence (SOC-13). Baseline scores of the SF-36 and WOMAC scales and the observed effect sizes after rehabilitation were correlated with the baseline SOC-13. These correlations of the SF-36 scales were compared to the Factor Score Coefficients for the Mental Component Summary of SF-36, which quantify the factor load on the psychosocial dimension. Predictive impact of the baseline SOC-13 for the SF-36 and WOMAC scales (baseline scores and effect sizes) was then determined by multivariate linear regression controlled for possible confounders. At baseline, the SOC-13 correlated with the WOMAC scores between r = 0.18 (stiffness) and r = 0.25 (pain) and with the SF-36 scores between r = 0.10 (physical functioning) and r = 0.53 (mental health). The correlation of these SF-36 correlation coefficients to the Factor Score Coefficient of the SF-36 Mental Component Summary was r = 0.95. The correlations for the effect sizes (baseline → discharge) with the baseline SOC-13 global score were all negative and varied between r = 0.00 (physical functioning) and r = -0.19 (social functioning). In the multivariate linear regression model, the explained variance of the SF-36 scores by the baseline SOC-13 increased continuously from physical to psychosocial health dimensions (from 12.9% to 29.8%). This gradient was consistently observed for both the baseline scores and the effect sizes. The results of the WOMAC were consistent with the physical health scales of SF-36. The sense of coherence was associated with psychosocial health dimensions but hardly with physical health. The higher the load of a scale on the psychosocial dimension the higher was its correlation to the sense of coherence. This is in contrast to the idea of Antonovsky who predicted high associations with both mental and physical health.

Background The 12-item Short Form Health Survey (SF-12) as a shorter alternative of the SF-36 is largely used in health outcomes surveys. The aim of this study was to validate the SF-12 in Iran. Methods A random sample of the general population aged 15 years and over living in Tehran, Iran completed the SF-12. Reliability was estimated using internal consistency and validity was assessed using known groups comparison and convergent validity. In addition, the factor structure of the questionnaire was extracted by performing both exploratory factor analysis (EFA) and confirmatory factor analysis (CFA). Results: In all, 5587 individuals were studied (2721 male and 2866 female). The mean age and formal education of the respondents were 35.1 (SD = 15.4) and 10.2 (SD = 4.4) years respectively. The results showed satisfactory internal consistency for both summary measures, that are the Physical Component Summary (PCS) and the Mental Component Summary (MCS); Cronbach's α for PCS-12 and MCS-12 was 0.73 and 0.72, respectively. Known-groups comparison showed that the SF-12 discriminated well between men and women and those who differed in age and educational status (P < 0.001). In addition, correlations between the SF-12 scales and single items showed that the physical functioning, role physical, bodily pain and general health subscales correlated higher with the PCS-12 score, while the vitality, social functioning, role emotional and mental health subscales more correlated with the MCS-12 score lending support to its good convergent validity. Finally the principal component analysis indicated a two-factor structure (physical and mental health) that jointly accounted for 57.8% of the variance. The confirmatory factory analysis also indicated a good fit to the data for the two-latent structure (physical and mental health). Conclusion In general the findings suggest that the SF-12 is a reliable and valid measure of health related quality of life among Iranian population. However, further studies are needed to establish stronger psychometric properties for this alternative form of the SF-36 Health Survey in Iran. PMID:19758427

Objective To examine 3-year quality-of-life (QOL) outcomes among United States adults with Diagnostic and Statistical Manual of Mental Disorders – Fourth Edition (DSM-IV) antisocial personality disorder (ASPD), syndromal adult antisocial behavior without conduct disorder (CD) before age 15 (AABS, not a DSM-IV diagnosis), or no antisocial behavioral syndrome at baseline. Method Face-to-face interviews (n= 34,653). Psychiatric disorders were assessed using the Alcohol Use Disorder and Associated Disabilities Interview Schedule – DSM-IV Version. Health-related QOL was assessed using the Short-Form 12-Item Health Survey, version 2 (SF-12v2). Other outcomes included past-year Perceived Stress Scale-4 (PSS-4) scores, employment, receipt of Supplemental Security Income (SSI), welfare, and food stamps, and participation in social relationships. Results ASPD and AABS predicted poorer employment, financial dependency, social relationship, and physical health outcomes. Relationships of antisociality to SSI and food stamp receipt and physical health scales were modified by baseline age. Both antisocial syndromes predicted higher PSS-4, AABS predicted lower SF-12v2 Vitality, and ASPD predicted lower SF-12v2 Social Functioning scores in women. Conclusion Similar prediction of QOL by ASPD and AABS suggests limited utility of requiring CD before age 15 to diagnose ASPD. Findings underscore the need to improve prevention and treatment of antisocial syndromes. PMID:22375904

Objectives To investigate whether life event stress was associated with greater psychological distress and poorer quality of life in older individuals with chronic obstructive pulmonary disease (COPD), in comparison with their counterparts without COPD. Design Cross-sectional study. Participants A population-based sample (N=497) of individuals aged 65 and above with COPD (postbronchodilatation FEV1/FVC<0.70, N=136) and without COPD (N=277). Measurements We measured life event stress, depressive symptoms (GDS, Geriatric Depression Scale), cognitive symptoms and function (CFQ, Cognitive Failures Questionnaire and MMSE, Mini-Mental State Examination), and physical and mental health functional status (SF36-PCS, Physical Health Component Summary and SF36-MCS, Mental Health Component Summary) in participants with and without COPD. Results In two-way analysis of variance controlling for potential confounders, life event stress was associated with significant main effects of worse GDS (p<0.001), SF36-PCS (p=0.008) and SF36-MCS scores (p<0.001), and with significant interaction effects on GDS score (p<0.001), SF36-PCS (p=0.045) and SF36-MCS (p=0.034) in participants with COPD, more than in non-COPD participants. The main effect of COPD was found for postbronchodilator FEV1 (p<0.001) and cognitive symptoms (p=0.02). Conclusions Our findings indicate that life event stress was associated with more depressive symptoms and worse quality of life in individuals with COPD, much more than in those without COPD. Further studies should explore the role of cognitive appraisal of stress, coping resources and psycho-social support in this relationship. PMID:23166130

Most studies regarding to air pollution were focused on forecasting Air Pollutant Index (API). Yet, there were no studies that conducted in Malaysia focused on Health-Related Quality of Life (HRQoL). The aim of this study was to investigate the HRQoL in two urban cities, which are Shah Alam and Putrajaya with different air pollution index. In doing so, SF36v2 questionnaire has been utilized to elicit data on HRQoL domains measured using eight domains (Physical Functioning, Role-Physical, Bodily Pain, General Health, Vitality, Social Functioning, Role-Emotional and Mental Health). A cross-sectional study was conducted and residents were selected using simple random sampling from Shah Alam and Putrajaya. The SF36v2 questionnaire with socio demographic information was distributed to the residents. A total of 266 participated in the study, of which 133 samples per groups. The statistical methods employed were descriptive analyses, independent samples t-test and MANOVA to analyze the HRQoL data. There was no difference in perceptions on HRQoL for Role Physical, Vitality, Social Functioning and Mental Health between residents in Shah Alam and residents in Putrajaya. However, there was difference in perception on HRQoL for Physical Functioning, Bodily Pain, General Health and Role Emotional.

To investigate associations among depression severity, painful physical symptoms (PPS), and social and occupational functioning impairment in patients with major depressive disorder (MDD) who had achieved complete remission (CR) or partial remission (PR) after acute treatment. This was a 12-week, multicenter, prospective, observational study. Patients with MDD treated with an antidepressant medication for the previous 12 weeks (±3 weeks) who had achieved CR (defined as a 17-item Hamilton Rating Scale for Depression [HAM-D17] score ≤7) or PR (HAM-D17 score ≥8 and ≤18) were enrolled. Depression severity, PPS, and impairment in social and occupational functioning were assessed using the HAM-D17, the Brief Pain Inventory (Short Form) (BPI-SF), and the Social and Occupational Functioning Assessment Scale (SOFAS), respectively, at enrollment (Week 12) and after 12 weeks (Week 24). Overall, 323 Japanese patients with MDD were enrolled (CR n=158, PR n=165) and 288 patients completed the study (CR n=139, PR n=149). HAM-D17 and SOFAS scores were strongly and negatively correlated at enrollment (Week 12; P <0.0001) and Week 24 ( P <0.0001). A weak negative correlation between the BPI-SF and SOFAS was observed at Week 24 ( P =0.0011), but not at enrollment ( P =0.164). Remission status at enrollment (CR or PR) was associated with achieving normal social and occupational functioning (SOFAS score ≥80) at Week 24 in patients who had not achieved normal social and occupational functioning (SOFAS score <80) at enrollment (CR vs PR, OR=0.05 [95% CIs 0.01-0.18], P <0.0001). A greater proportion of patients with CR and no PPS at enrollment achieved SOFAS scores ≥80 at Week 24 than those with CR and PPS. Our results suggest that treating both depressive symptoms and PPS is important for achieving a normal level of functioning on a long-term basis in patients with MDD.

To compare parameters of attention in healthy people and patients with neoplasms in different regions of the cerebral cortex and to evaluate quality of life (QoL) indices with regard to impairment of different attention systems. Twenty patients with oncological lesions of the brain (mean age 56.5±8.8 years) who did not undergo surgery were studied. Tumor localization was confirmed using contrast-enhanced computed tomography, the tumor type was histologically verified. A control group included 18 healthy people matched for age, sex and education level. To determine attention system functions, we developed a computed version of the Attention Network Test. Error rate and reaction time for correct responses to the target stimulus, displayed along with neutral, congruent and incongruent signals, were the indicators of the efficacy of selective processes. QoL indices were assessed using SF-36 health survey questionnaire. The readiness to respond to incoming stimuli was mostly impaired in patients with brain tumors. Efficacy of executive attention, assessed as the increase in the number of errors in selection of visual stimuli, was decreased while temporary parameters of the functions of this system were not changed in patients compared to controls. The SF-36 total score was stable in patients with marked reduction in scores on the Role and Emotional Functioning scales. The most severe health impairment measured on the SF-36 scales of role/social emotional functioning and viability was recorded in patients with the lesions of frontal cortical areas compared to temporal/parietal areas. The relationship between SF-36 Health self-rating and attention systems was found. This finding puts the question of the importance of attention characteristics and QoL for survival prognosis of patients with brain tumors.

Purpose: Erectile dysfunction is one of the most concerning toxicities for patients in the treatment of prostate cancer. The inconsistent evaluation of sexual function (SF) and limited follow-up data have necessitated additional study to clarify the rate and timing of erectile dysfunction after external beam radiotherapy (EBRT) for prostate cancer. Methods and Materials: A total of 143 men completed baseline data on SF before treatment and at the subsequent follow-up visits. A total of 1187 validated SF inventories were analyzed from the study participants. Multiple domains of SF (sex drive, erectile function, ejaculatory function, and overall satisfaction) were analyzed formore » <=8 years of follow-up. Results: The median follow-up was 4.03 years. The strongest predictor of SF after EBRT was SF before treatment. For all domains of SF, the only statistically significant decrease in function occurred in the first 24 months after EBRT. SF stabilized 2 years after treatment completion, with no statistically significant change in any area of SF >2 years after the end of EBRT. Conclusion: These data suggest that SF does not have a continuous decline after EBRT. Instead, SF decreases maximally within the first 24 months after EBRT, with no significant changes thereafter.« less

Urinary incontinence (UI) has been associated with chronic respiratory symptoms, and it affects quality of life. This study evaluated the quality of life of asthmatic patients from the Assistance Program for Asthmatic Patients (PAPA) with and without UI. This is an analytical descriptive cross-sectional study using a sample of 358 women with asthma. Data were collected via the International Consultation Incontinence Questionnaire-Simplified Form (ICIQ-SF), Quality of Life in Asthma Questionnaire (QLAQ-ASTHMA) and Short Form 36 Health Survey (SF-36). We found a general prevalence of UI of 55.3%. Overall quality of life scores in the SF-36 and QLAQ-ASTHMA were not related to the presence of UI. However, the amount of urine lost was significantly correlated with the subdomains physical aspects, general health, social functioning and mental health of the SF-36 and with socioeconomic and psychosocial domains of the QLAQ-ASTHMA. Urinary incontinence may affect a large proportion of older women with asthma. This study demonstrates the importance of routinely evaluating the occurrence of UI in order to improve the quality of life of asthmatic patients.

To examine the associations of mental health functioning with intentions to retire early among ageing municipal employees. Cross-sectional survey data (n = 7,765) from the Helsinki Health Study in 2000, 2001, and 2002 were used. Intentions to retire early were sought with a question: "Have you considered retiring before normal retirement age?" The dependent variable was divided into three categories: 1 = no intentions to retire early; 2 = weak intentions; 3 = strong intentions. Mental health functioning was measured by the Short Form 36 (SF-36) mental component summary (MCS). Other variables included age, sex, physical health functioning (SF-36), limiting longstanding illness, socioeconomic status, and spouse's employment status. Multinomial regression analysis was used to examine the association of mental health functioning with intentions to retire early. Employees with the poorest mental health functioning were much more likely to report strong intentions to retire early (OR 6.09, 95% CI 4.97-7.47) than those with the best mental health functioning. Adjustments for physical health, socioeconomic status, and spouse's employment status did not substantially affect this association. The findings highlight the importance of mental health for intentions to retire early. Strategies aimed at keeping people at work for longer should emphasize the importance of mental well-being and the prevention of poor mental health. More evidence is needed on why mental problems among ageing baby-boomer employees are giving rise to increasing social consequences, although the overall prevalence of mental problems has not increased.

To describe the prevalence and control of diabetes in the adult population served by the Instituto Mexicano del Seguro Social according to data from the National Health Survey 2000 (ENSA-2000). The data for adults from the National Health Survey 2000 was used to estimate and describe the prevalence of diabetes in the population that belongs to the social security system in Mexico. Criteria used to define diabetes mellitus were the medical diagnosis of the disease (MDDM) and the glucose measurement from capillary blood (>126 mg/dL fasting sample and 200 mg/dL in casual blood sample). If diabetes was confirmed only through blood sample, the diabetes case was define as survey finding (SF). Prevalences were estimated for both groups, while means and medians were estimated for the four possible combination groups (SF+, MDDM+, SF+, MDDM-, SF-, MDDM+, SF-, MDDM-). Sampling results were adjusted for population estimates according to the methods established in the ENSA-2000. Diabetes is described according to age, sex, education level, geographic region, background of diabetes in the family, body mass index (BMI), abdominal perimeter. A logistic regression method was used to estimate potential associations with different risk factors. Overall prevalence was 8.7%; for MDDM, it was 7.1%, and for SF, only 1.5%. Glycemia was highest in SF+ and MDDM-, median 292 mg/dL and in MDDM+ but SF-, median 289 mg/dL. Major risk factors were background of diabetes in both parents, abdominal obesity, low educational level age (coef. = 0.5943 per decade) and BMI (coef. = 0.0133). Diabetes in social security population is higher than in the rest of the population, while genetic background, age, educational level, high BMI and abdominal perimeter have important influences in diabetes prevalence in this population. Glucose control is suboptimal even in patients under medical supervision.

Objective The current review describes how the health status profile of people with fibromyalgia (FM) compares to that of people in the general population and patients with other health conditions. Methods A review of 37 studies of FM that measured health status with the 36-item Medical Outcomes Study Short-Form Health Survey (SF-36) or the 12-item Short-Form Health Survey (SF-12). Results Studies performed worldwide showed that FM groups were significantly more impaired than people in the general population on all eight health status domains assessed. These domains include physical functioning, role functioning difficulties caused by physical problems, bodily pain, general health, vitality (energy vs. fatigue), social functioning, role functioning difficulties caused by emotional problems and mental health. FM groups had mental health summary scores that fell 1 standard deviation (SD) below the general population mean, and physical health summary scores that fell 2 SD below the general population mean. FM groups also had a poorer overall health status compared to those with other specific pain conditions. FM groups had similar or significantly lower (poorer) physical and mental health status scores compared to those with rheumatoid arthritis, osteoarthritis, osteoporosis, systemic lupus erythematosus, myofacial pain syndrome, primary Sjögren's syndrome and others. FM groups scored significantly lower than the pain condition groups mentioned above on domains of bodily pain and vitality. Health status impairments in pain and vitality are consistent with core features of FM. Conclusions People with FM had an overall health status burden that was greater in magnitude compared to people with other specific pain conditions that are widely accepted as impairing. Review Criteria Studies in this review were identified through a search of electronic databases (MEDLINE: 1990–2006; EMBASE: 1990–2006). Search terms included: ‘fibromyalgia’, ‘health status’, ‘quality of life’, ‘SF-36’ and ‘SF-12’. Reference lists from published articles were also searched. Studies were selected if they were published in the English language between 1990 and (March) 2006 and assessed health status with a validated version of the SF-36 or the SF-12. Message for the Clinic Although FM is a controversial construct, studies performed worldwide showed that the health status profile of people with FM was remarkably consistent. People with FM had significant impairments in both mental and physical health status domains. People with FM had a poorer overall health status than people with specific pain conditions that are widely accepted as impairing. PMID:18039330

Self-reported health status measures, like the Short Form 36-item Health Survey (SF-36), can provide rich information about the overall health of a population and its components, such as physical, mental, and social health. However, differential item functioning (DIF), which arises when population sub-groups with the same underlying (i.e., latent) level of health have different measured item response probabilities, may compromise the comparability of these measures. The purpose of this study was to test for DIF on the SF-36 physical functioning (PF) and mental health (MH) sub-scale items in a Canadian population-based sample. Study data were from the prospective Canadian Multicentre Osteoporosis Study (CaMos), which collected baseline data in 1996-1997. DIF was tested using a multiple indicators multiple causes (MIMIC) method. Confirmatory factor analysis defined the latent variable measurement model for the item responses and latent variable regression with demographic and health status covariates (i.e., sex, age group, body weight, self-perceived general health) produced estimates of the magnitude of DIF effects. The CaMos cohort consisted of 9423 respondents; 69.4% were female and 51.7% were less than 65 years. Eight of 10 items on the PF sub-scale and four of five items on the MH sub-scale exhibited DIF. Large DIF effects were observed on PF sub-scale items about vigorous and moderate activities, lifting and carrying groceries, walking one block, and bathing or dressing. On the MH sub-scale items, all DIF effects were small or moderate in size. SF-36 PF and MH sub-scale scores were not comparable across population sub-groups defined by demographic and health status variables due to the effects of DIF, although the magnitude of this bias was not large for most items. We recommend testing and adjusting for DIF to ensure comparability of the SF-36 in population-based investigations.

The diagnosis of chronic kidney disease (CKD) in elderly individuals has been increasing. The objective of this study was to evaluate physical, mental and social aspects in longevous elderly patients with CKD. Eighty patients with CKD (stage 4 and 5, not on dialysis) and 60 longevous elderly (≥ 80 years) paired by gender and age living in the community were evaluated. Physical, cognitive, social and quality of life aspects were analyzed according to the following scales: Charlson comorbidity index, Medical Outcomes Study Short Form 36-Item (SF-36), Medical Outcomes Study, Boston Naming Test, verbal fluency test (animal naming), sit-to-stand test, gait speed, and the Mini-Mental state examination. Compared to the control group, the CKD group had a higher mean in the comorbidities index (3.5 ± 1.2 vs. 1.0 ± 1, respectively, p < 0.001). In the multivariate analysis, the CKD group presented worse performance in the SF-36 dimensions: 'physical functioning,' 'general health,' 'emotional functioning,' 'vitality,' and physical component summary. On the other hand, they presented better results for the 'mental health' dimension, in addition to lower  social support, worse verbal fluency and worse results on the sit-to-stand test. Longevous patients with stage 4 or 5 CKD presented worse evaluation in several domains of physical and emotional functioning, lower social support and evidence of worse cognitive performance. These aspects should be taken into account in order to improve the care provided to these patients, improve their quality of life and prevent their morbidity.

To assess prospectively the effects of perceived non-reciprocity of exchange in three different types of social engagement on health functioning in early old age. In the frame of the prospective French GAZEL cohort study, data on reciprocity in three types of role-related social engagement (principal regular activity in everyday life, marital role relationship, trusting relationships in civic life) were collected from 8679 men and 2742 women (mean age: 60.4 years) in 2005. Two years later, health functioning was assessed using the SF-36 mental and physical component scores, as well as self-perceived health. Multivariate regressions were calculated, controlling for important confounders including baseline self-perceived health. Consistent effects of perceived non-reciprocity in all three types of social exchange on mental and physical health functioning were observed. After adjustment for relevant confounders including baseline self-perceived, health effects were attenuated, but largely remained significant. Findings underline the importance of the quality of social exchange (reciprocity vs. non-reciprocity) for health functioning in early old age.

Our aim in the present study was to determine whether a disease-specific self-management program for primary care patients with osteoarthritis (OA) of the knee (the Osteoarthritis of the Knee Self-Management Program (OAK)) implemented by health care professionals would achieve and maintain clinically meaningful improvements in health-related outcomes compared with a control group. Medical practitioners referred 146 primary care patients with OA of the knee. Volunteers with coexistent inflammatory joint disease or serious comorbidities were excluded. Randomisation was to either a control group or the OAK group. The OAK group completed a 6-week self-management program. The control group had a 6-month waiting period before entering the OAK program. Assessments were taken at baseline, 8 weeks and 6 months. The primary outcomes were the results measured using the Western Ontario and McMaster Universities Arthritis Index (WOMAC) Pain and Function subscales on the Short Form 36 version 1 questionnaire (SF-36) Secondary outcomes were Visual Analogue Scale (VAS) pain, Timed Up & Go Test (TUG), knee range of motion and quadriceps and hamstring strength-isometric contraction. Responses to treatment (responders) and minimal clinically important improvements (MCIIs) were determined. In the OAK group, VAS pain improved from baseline to week 8 from mean (SEM) 5.21 (0.30) to 3.65 (0.29) (P ≤ 0.001). During this period, improvements in the OAK group compared with the control group and responses to treatment were demonstrated according to the following outcomes: WOMAC Pain, Physical Function and Total dimensions, as well as SF-36 Physical Function, Role Physical, Body Pain, Vitality and Social Functioning domains. In addition, from baseline to week 8, the proportion of MCIIs was greater among the OAK group than the control group for all outcomes. For the period between baseline and month 6, WOMAC Pain, Physical Function and Total dimensions significantly improved in the OAK group compared to the control group, as did the SF-36 Physical Function, Role Physical, Body Pain, Vitality and Social Functioning domains, as well as hamstring strength in both legs. During the same period, the TUG Test, range of motion extension and left-knee flexion improved compared with the control group, although these improvements had little clinical relevance. We recorded statistically significant improvements compared with a control group with regard to pain, quality of life and function for participants in the OAK program on the basis of WOMAC and SF-36 measures taken 8 weeks and 6 months from baseline.

We report the findings of a randomized controlled trial to determine the effectiveness of a multidisciplinary Stroke Education Program (SEP) for patients and their informal carers. Two hundred four patients admitted with acute stroke and their 176 informal carers were randomized to receive an invitation to the SEP or to receive conventional stroke unit care. The SEP consisted of one 1-hour small group educational session for inpatients followed by six 1-hour sessions after discharge. The primary outcome measure was patient- and carer-perceived health status (SF-36) at 6 months after stroke. Knowledge of stroke, satisfaction with services, emotional outcome, disability, and handicap and were secondary outcome measures. Only 51 of 108 (47%) surviving patients randomized to the SEP completed the program, as did 20 of 93 (22%) informal carers of surviving patients. Perceived health status (Short Form 36 [SF-36] health survey) scores were similar for SEP patients and controls. Informal carers in the control group scored better on the social functioning component of the SF-36 than the SEP group (P=0.04). Patients and informal carers in the SEP group scored higher on the stroke knowledge scale than controls (patients, P=0.02; carers, P=0. 01). Patients in the SEP group were more satisfied with the information that they had received about stroke (P=0.004). There were no differences in emotional or functional outcomes between groups. Although the SEP improved patient and informal carer knowledge about stroke and patient satisfaction with some components of stroke services, this was not associated with an improvement in their perceived health status. Indeed, the social functioning of informal carers randomized to the SEP was less than in the control group.

To test psychometrics of the Short Form 36 Health Survey version 2 (SF-36v2) and the Quality of Life Scale for Drug Addicts (QOL-DAv2.0) in Chinese mainland patients with methadone maintenance treatment (MMT). A total of 1,212 patients were recruited from two MMT clinics in Xi'an, China. Reliability was estimated with Cronbach's α and intra-class correlation (ICC). Convergent and discriminant validity was assessed using multitrait-multimethod correlation matrix. Sensitivity was measured with ANOVA and relative efficiency. Responsiveness was evaluated by pre-post paired-samples t-test and standardized response mean based on the patients' health status changes following 6-month period. Cronbach's α of the SF-36v2 physical and mental summary components were 0.80 and 0.86 (eight scales range 0.73-0.92) and the QOL-DAv2.0 was 0.96 (four scales range: 0.80-0.93). ICC of the SF-36v2 two components were 0.86 and 0.85 (eight scales range: 0.72-0.87) and the QOL-DAv2.0 was 0.94 (four scales range: 0.88-0.92). Convergent validity was lower between the two instruments (γ <0.70) while discriminant validity was acceptable within each instrument. Sensitivity was satisfied in self-evaluated health status (both instruments) and average daily methadone dose (SF-36v2 physical functioning and vitality scales; QOL-DAv2.0 except psychology scale). Responsiveness was acceptable in the improved health status change (SF-36v2 except vitality scale; QOL-DAv2.0 except psychology and symptoms scales) and deteriorated health status change (SF-36v2 except vitality, social functioning and mental health scales; QOL-DAv2.0 except society scale). The SF-36v2 and the QOL-DAv2.0 are valid tools and can be used independently or complementary according to different emphases of health-related quality of life evaluation in patients with MMT.

Sexual function (SF) is an important component of patient-focused health related quality of life (HRQoL), but it has not been well studied in spine surgery. This study aims to assess SF after cervical spine surgery and identify predictors of SF. This single-center retrospective study evaluates SF of adults who underwent cervical spine surgery 2007-2012. Predictor variables included demographics, medical/surgical history, operative information, HRQoL measures (Neck Disability Index, SF-12), validated SF surveys [Female Sexual Function Index (FSFI) and Brief Sexual Function Inventory (BSFI) for males], and a study-specific SF questionnaire. 59 patients (31M, 28F; mean age=56±8.4) had significantly lower SF scores compared to age-matched peers: average BSFI = 2.26±1.22 (vs. 06±0.74), average FSFI=13.05±11.42 (<26.55 indicating sexual dysfunction). In men, lower mental SF-12 and higher NDI, back pain, and number of operated levels were associated with lower BSFI scores (all p<0.05). In women, higher total number of medications and pain medications were associated with lower FSFI scores (both p<0.05). 46% of patients reported difficulty performing a sexual position after surgery that they had previously enjoyed. 39% of men had difficulty on top during intercourse, and 32% of participants reported difficulty performing oral sex. 39% of patients reported worse SF, while only 5% reported an improvement in postoperative SF. Men and women who underwent cervical spine surgery had lower SF scores than age-matched peers, likely attributable to general mental health, regional neck disability, back pain, and medications. A large portion of patients reported subjectively worsened SF after surgery. Copyright © 2016 Elsevier Ltd. All rights reserved.

Depression and pain frequently occur together. The objective of this study was to investigate the effects of depression and pain on the impairment of daily functioning and quality of life (QOL) of depressed patients. We enrolled 131 acutely ill inpatients with major depressive disorder. Depression, pain, and daily functioning were assessed using the 17-item Hamilton Depression Rating Scale, the Short-Form 36 (SF-36) Body Pain Index, and the Work and Social Adjustment Scale. Health-related QOL was assessed using three primary domains of the SF-36: social functioning, vitality, and general health perceptions. Pearson׳s correlation and structural equation modeling were used to examine relationships among the study variables. Five models were proposed. In all, 129 patients completed all the measures. Model 5, both depression and pain impaired daily functioning and QOL, was the most fitted structural equation model (χ(2)=9.2, df=8, p=0.33, GFI=0.98, AGFI=0.94, TLI=0.99, CFI=0.99, RMSEA=0.03). The correlation between pain and depression was weak (r=-0.27, z=-2.95, p=0.003). This was a cross-sectional study with a small sample size. Depression and pain exert a direct influence on the impairment of daily functioning and QOL of depressed patients; this impairment could be expected regardless of increased pain, depression, or both pain and depression. Pain had a somewhat separate entity from depression. Copyright © 2014. Published by Elsevier B.V.

Due to the multilineage differentiation ability and paracrine role of adipose-derived stem cells (ASCs) for bladder defect repair, various scaffolds have been applied in combination with ASCs to promote bladder regeneration and restore bladder function. However, the low survival rate of ASCs and the difficulty of promoting bladder functional recovery are still unsolved. To explore these problems, we investigated the feasibility of a novel scaffold seeded with ASCs in a rat model of bladder augmentation. A novel autologous myofibroblast (AM)-silk fibroin (SF) scaffold was harvested after subcutaneously prefabricating the bladder acellular matrix grafts (BAMG) and SF by removing the BAMG. The AM-SF scaffolds were then seeded with ASCs (AM-SF-ASCs). Fifty percent supratrigonal cystectomies were performed followed by augmenting the cystectomized defects with AM-SF scaffolds or AM-SF-ASCs. The histological and functional assessments of bladders were performed 2, 4, and 12 weeks after surgery while the ASCs were tracked in vivo. For bladder tissue regeneration, immunofluorescence analysis revealed that AM-SF-ASCs (the experimental group) promoted better morphological regeneration of the urothelium, vessels, bladder smooth muscle, and nerve than AM-SF scaffolds (the control group). Regarding functional restoration, the AM-SF-ASC group exhibited higher bladder compliance and relatively normal micturition pattern compared to the AM-SF group. In addition, a certain number of surviving ASCs could be found in vivo 12 weeks after implantation, and some of them had differentiated into smooth muscle cells. The AM-SF scaffolds with ASCs could rapidly promote bladder morphological regeneration and improved bladder urinary function. In addition, the bag-shaped structure of the AM-SF scaffold can improve the survival of ASCs for at least 12 weeks. This strategy of AM-SF-ASCs has a potential to repair large-scale bladder defects in the clinic in the future.

More knowledge is needed about men with sex chromosome aneuploidies (SCA). We present self-reported data from 53 men with SCA (M age = 36.8 years, SD = 12.3, range 19-67). The Health Survey-Short Form (SF-36) measured eight health domains (physical functioning, role-physical, role-emotional, vitality, emotional health, social functioning, pain, general health). The Pittsburgh Sleep Quality Index measured sleep problems. The Personal Wellbeing Index measured satisfaction with eight life domains. Compared to norms, SCA reported poorer health (mean d = -0.80) and more sleep problems (mean d = -0.85). Differences between SCA and norms on personal well-being were small, except lower health satisfaction in SCA (d = -1.06). Seven of eight regression models predicting the SF-36 domains from life satisfaction and sleep problems were significant (explained variance 12.2% to 46.2%), except physical functioning (ns). Clinical assessment/intervention for a broad range of health and sleep problems is indicated for men with SCA.

Health-Related Quality of Life in Men with Erectile Dysfunction

OBJECTIVE To assess health-related quality of life (HRQOL) in men with erectile dysfunction. DESIGN Descriptive survey with general and disease-specific measures. The instrument contained three established, validated HRQOL measures, a validated comorbidity checklist, and sociodemographics. The RAND 36-Item Health Survey 1.0 (SF-36) was used to assess general HRQOL. Sexual function and sexual bother were assessed using the UCLA Prostate Cancer Index. The marital interaction scale from the Cancer Rehabilitation Evaluation System Short Form (CARES-SF) was used to assess each patient's relationship with his sexual partner. SETTING Urology clinics at a university medical center and the affiliated Veterans Affairs (VA) Medical Center. PARTICIPANTS Thirty-five (67%) of 54 consecutive university patients presenting for erectile dysfunction and 22 (42%) of 52 VA patients who were awaiting a previously prescribed vacuum erection device participated. MAIN RESULTS The university respondents scored slightly lower than population normals in social function, role limitations due to emotional problems, and emotional well-being. The VA respondents scored lower than expected in all eight domains. Scores for the VA population were significantly lower than those for the university population in physical function, role limitations due to physical problems, bodily pain, and social function. A significant correlation was seen between marital interaction and sexual function (r = −.33, p = .01) but not between marital interaction and sexual bother (r = −.15, p = .26) in the total sample. Sexual function also correlated significantly with general health perceptions (r = .34, p = .01), role limitations due to physical problems (r = .29, p = .03), and role limitations due to emotional problems (r = .30, p = .03). Sexual bother did not correlate with any of the general HRQOL domains. Affluent men reported better sexual function (p = .03). CONCLUSIONS The emotional domains of the SF-36 are associated with more profound impairment than are the physical domains in men with erectile dysfunction. Erectile dysfunction and the bother it causes are discrete domains of HRQOL and distinct from each other in these patients. With increased attention to patient-centered medical outcomes, greater emphasis has been placed on such variables as HRQOL. This should be particularly true for a patient-driven symptom, such as erectile dysfunction. PMID:9541372

Differential regulation of cellular functions by the C-termini of transmembrane 4 L six family proteins in 2- or 3-dimensional environment.

The transmembrane 4 L six family proteins TM4SF1, TM4SF4, and TM4SF5 share 40-50% overall sequence identity, but their C-terminus identity is limited. It may be likely that the C-termini of the members are important and unique for own regulatory functions. We thus examined how the TM4SF5 C-terminus affected cellular functions differentially from other family members. Using colon cancer cells expressing wildtype (WT), C-terminus-deleted, or chimeric mutants, diverse cellular functions were explored in 2-dimensional (2D) and 3-dimensional (3D) condition. The C-termini of the proteins were relatively comparable with respect to 2D cell proliferation, although each C-terminal-deletion mutant exhibited increased proliferation relative to the WT. Using chimeric constructs, we found that the TM4SF5 C-terminus was critical for regulating the diverse metastatic functions of TM4SF5, and could positively replace the C-termini of other family members. Replacement of the TM4SF1 or TM4SF4 C-terminus with that of TM4SF5 increased spheroids growth, transwell migration, and invasive dissemination from spheroids in 3D collagen gels. TM4SF5-mediated effects required its extracellular loop 2 linked to the C-terminus via the transmembrane domain 4, with causing c-Src activation. Altogether, the C-terminus of TM4SF5 appears to mediate pro-migratory roles, depending on a structural relay from the second extracellular loop to the C-terminus.

To examine the effect of multidisciplinary ALS care on the quality-of-life (QoL) in patients with ALS and their caregivers. In a cross-sectional study, 208 patients with ALS and their caregivers were interviewed. QoL was assessed using the 36-item Short Form Health Survey (SF-36) and two visual analogue scales (VAS). Criteria for multidisciplinary ALS care were: an ALS team headed by a consultant in rehabilitation medicine and consisting of at least a physical therapist, occupational therapist, speech pathologist, dietician and a social worker; use of the Dutch ALS consensus guidelines for ALS care; and at least six incident ALS patients per year. Clinical characteristics and functional loss of the 133 patients receiving multidisciplinary ALS care and the 75 patients receiving general ALS care were similar. The percentage of patients with adequate aids and appliances was higher in those with multidisciplinary ALS care (93.1 vs 81.3%, p = 0.008), whereas the number of visits to professional caregivers was similar in both groups. Patients in the multidisciplinary ALS care group had a better mental QoL on the SF-36 Mental Summary Score than those in the general care group (p = 0.01). The difference in QoL was most pronounced in the domains of Social Functioning and Mental Health, and was independent of the presence of aids and appliances. No significant differences were found in the SF-36 Physical Summary Score, VAS, or in QoL of caregivers of patients with ALS. High standard of care improves mental quality-of-life in patients with ALS.

Population studies demonstrate that attending cultural events is conducive to improved health when baseline health, income, education, and health habits are taken into account. Animal experiments suggest possible mechanisms. We studied the link in humans between attending cultural events and health in a randomized controlled trial. Members of the local government officers' union in the health services in Umeå, Sweden, were invited to the experiment and 101 people registered for fine arts visits once a week for 8 weeks. They chose films, concerts, or art exhibitions visits, or singing in a choir and were then randomized into 51 cases, starting at once, and 50 controls starting after the trial. Health was assessed before randomization and after the experimental period using the instrument for perceived health, short form (SF)-36, and tests of episodic memory, saliva-cortisol and immunoglobulin. The results were analyzed using a mixed design analysis of variance. The SF-36 Composite Score called physical health improved in the intervention group and decreased among controls during the experiment (F(1,87) = 7.06, p = .009). The individual factor of the SF-36 called social functioning, improved more in the intervention group than among controls (F(1,98) = 8.11, p = .005) as well as the factor vitality (F(1,98) = 5.26, p = .024). The six other factors and the Mental Health Composite Score, episodic memory, cortisol and immunoglobulin levels did not change otherwise than among controls. Mechanisms are left to be identified. Fine arts stimulations improved perceived physical health, social functioning, and vitality.

The aim of this study was to analyze the patient demographics, etiology of limb loss as well as reporting SF-36 scores for microprocessor prosthesis users in Turkish population. We reviewed 72 patients (61 male and 11 female; mean age: 37.7 ± 10.7) with uni-lateral, above knee amputation and a history of regular and microprocessor prosthesis use. All patients were called back for a last follow-up and they were asked to fill a self-administered general health status questionnaire (SF-36). According to the SF-36 results; physical component score (PCS) score was 46 ± 7.3 and mental components summary (MCS) score was 46.5 ± 9.1. These scores have statistical similarity with Turkish healthy controls, except SF (social functioning) sub-dimension. PCS score for women microprocessor users were significantly lower than men (43.3 vs. 48.7, p = 0.03), but MCS scores were similar in between genders (46 vs. 48.2, p = 0.13). Conventional prostheses usage time was positively correlated with physical function (PF) scores (r = 0.322, p = 0.010). Microprocessor prosthesis usage time was negatively correlated with role limitations due to emotional problem (RE) scores (r = -0,313, p = 0.009). The quality of life surveys were showed that the loss of an extremity have higher physical and psychological impact on women's physical scores. Overall, SF-36 results were similar in microprocessor using amputee's and Turkish normal controls. Level IV, therapeutic study. Copyright © 2017 Turkish Association of Orthopaedics and Traumatology.

Levomilnacipran extended-release (ER) is an FDA-approved serotonin norepinephrine reuptake inhibitor (SNRI) for treating major depressive disorder (MDD). SF-36v2 Health Survey outcomes from a Phase III, randomized, double-blind, placebo-controlled study (NCT00969709) were evaluated. Prospective and post hoc analyses of SF-36 Mental and Physical Component Summaries (MCS, PCS), and individual domains compared pooled levomilnacipran ER doses (40, 80, 120 mg/day) with placebo. Patients (18-65 years) had MDD, depressive episode ≥ 8 weeks, and Montgomery-Åsberg Depression Rating Scale total score ≥ 30. SF-36 score changes from baseline to Week 8 were analyzed using ANCOVA and the observed cases approach (Intent-to-Treat [ITT] Population). Minimally important differences (MID) evaluated clinical relevance. Baseline MCS scores reflected marked mental deficits in the ITT Population (levomilnacipran ER = 529; placebo = 175). MCS change at Week 8 was significantly greater for levomilnacipran ER than placebo (LSMD [SE] = 4.8 [1.5]; P = 0.0011); MID exceeded the 3-point threshold. Baseline PCS scores suggested minimal physical deficits; no between-group difference at Week 8 was noted. LSMD was nominally statistically significant (P < 0.05) for levomilnacipran ER versus placebo in 5 domains (General Health [2.44; P = 0.0010], Vitality [2.48; P = 0.0307], Social Functioning [3.25; P = 0.0097], Role-Emotional [3.38; P = 0.0078], Mental Health [4.34; P = 0.0005]); changes in Vitality, Social Functioning, and Mental Health exceeded MID. The trial was limited by short duration; analyses were post hoc and adjustments were not made for multiplicity. Statistically significant and clinically meaningful improvement on the MCS and several individual domains suggest overall and dimensional improvement in health-related functioning for patients with MDD treated with levomilnacipran ER versus placebo.

Maher, Colleen; Mendonca, Rochelle J

We evaluated the impact of a 1-wk activity program on the health, quality of life (QOL), and occupational performance of community-living women diagnosed with cancer. A one-group pretest-posttest repeated-measures design was used. Participants completed a functional health measure (36-Item Short Form Health Survey [SF-36]), a QOL measure (World Health Organization Quality of Life-Brief version [WHOQOL-BREF]), and an occupational performance and satisfaction measure (Canadian Occupational Performance Measure [COPM]) before and 6 wk after program completion. The COPM was also administered on Day 5. Paired t tests for the SF-36 and WHOQOL-BREF showed no significant differences, except for the WHOQOL-BREF's Social Relationships subscale (p < .008). Repeated-measures analyses of variance showed a significant difference in COPM performance and satisfaction scores (p < .001). The activity program effectively improved occupational performance and satisfaction and social relationships of community-living women diagnosed with cancer.

The 12-item medical outcomes study short form health survey version 2.0 (SF-12v2): a population-based validation study from Tehran, Iran

PubMed Central

2011-01-01

Background The SF-12v2 is the improved version of the SF-12v1. This study aimed to validate the SF-12v2 in Iran. Methods A random sample of the general population aged 18 years and over living in Tehran, Iran completed the instrument. Reliability was estimated using internal consistency and validity was assessed using known-groups comparison and convergent validity. In addition the factor structure of the questionnaire was extracted by performing both exploratory and confirmatory factor analyses (EFA and CFA). Results In all, 3685 individuals were studied (1887male and 1798 female). Internal consistency for both summary measures was satisfactory. Cronbach's α for the Physical Component Summary (PCS-12) was 0.87 and for the Mental Component Summary (MCS-12) it was 0.82. Known-groups comparison showed that the SF-12v2 discriminated well between men and women and those who differed in age and educational status (P < 0.05). Furthermore, as hypothesized the physical functioning, role physical, bodily pain and general health subscales correlated higher with the PCS-12, while the vitality, social functioning, role emotional and mental health subscales correlated higher with the MCS-12. Finally the exploratory factor analysis indicated a two-factor structure (physical and mental health) that jointly accounted for 59.9% of the variance. The confirmatory factory analysis also indicated a good fit to the data for the two-latent structure (physical and mental health). Conclusion Although the findings could not be generalized to the Iranian population, overall the findings suggest that the SF-12v2 is a reliable and valid measure of health related quality of life among Iranians and now could be used in future health outcome studies. However, further studies are recommended to establish its stability, responsiveness to change, and concurrent validity for this health survey in Iran. PMID:21385359

To examine the relationship between Short Form (SF)-36 physical functional health-related quality of life and incident stroke. A total of 13,615 men and women participating in the European Prospective Investigation into Cancer-Norfolk who were free of stroke, myocardial infarction, and cancer at baseline were included in the study. Participants completed a health and lifestyle questionnaire and attended a health examination during 1993 to 1997. Self-reported physical functional health was assessed using physical component summary scores of SF-36 18 months later. Stroke incidence was ascertained by death certification and hospital record linkage up to 2005. There were 244 incident strokes (total person years = 99,191). People who reported better physical functional health had significantly lower risk of incident stroke. Using Cox proportional hazard models adjusting for age, sex, body mass index, systolic blood pressure, cholesterol, smoking, diabetes, physical activity, social class, alcohol consumption, and respiratory function, men and women who were in the top quartile of SF-36 physical component summary scores had half the risk of stroke (RR = 0.50 [0.31, 0.78]) compared to the people in the bottom quartile. The relationships remained unchanged after excluding strokes occurring within the first 2 years of follow-up. Physical functional health-related quality of life measured as Short Form-36 predicts subsequent stroke risk independently of known risk factors in a general population. Poor physical functional health may indicate a high-risk population for stroke who may benefit most from targeted preventive interventions such as management of known risk factors.

Reliability of well-known instruments was examined in 202 people with severe mental illness participating in a multisite vocational study. We examined interrater reliability of the Positive and Negative Syndrome Scale (PANSS) and the internal consistency and test-retest reliability of the PANSS, the Rosenberg Self-Esteem Scale, the Medical Outcomes Study Short Form-36 (SF-36), and the Quality of Life Interview. Most scales had good levels of reliability, with intraclass correlation coefficients (ICCs) and coefficient alphas above .70. However, the SF-36 scales were generally less stable over time, particularly Social Functioning (ICC = .55). Test-retest reliability was lower among less educated respondents and among ethnic minorities. We recommend close monitoring of psychometric issues in future multisite studies.

Chronic heart failure (CHF), a major public health problem worldwide, seriously limits health-related quality of life (HRQOL). How to evaluate HRQOL in older patients with CHF remains a problem. To evaluate the reliability and validity of the Chinese version of the Medical Outcomes Study Short Form version 2 (SF-36v2) in CHF patients. From September 2012 to June 2014, we assessed QOL using the SF-36v2 in 171 aging participants with CHF in four cardiology departments. Convergent and discriminant validity, factorial validity, sensitivity among different NYHA classes and between different age groups, and reliability were determined using standard measurement methods. A total of 150 participants completed a structured questionnaire including general information and the Chinese SF-36v2; 132 questionnaires were considered valid, while 21 patients refused to take part. 25 of the 50 participants invited to complete the 2-week test-retest questionnaires returned completed questionnaires. The internal consistency reliability (Cronbach's α) of the total SF-36v2 was 0.92 (range 0.74-0.93). All hypothesized item-subscale correlations showed satisfactory convergent and discriminant validity. Sensitivity was measured in different NYHA classes and age groups. Comparison of different NYHA classes showed statistical significance, but there was no significant difference between age groups. We confirmed the SF-36v2 as a valid instrument for evaluating HRQOL Chinese CHF patients. Both reliability and validity were strongly satisfactory, but there was divergence in understanding subscales such as "social functioning" because of differing cultural background. The reliability, validity, and sensitivity of SF-36v2 in aging patients with CHF were acceptable.

The interpretation of studies on quality of life (QoL) after lung surgery is often difficult owing to the use of multiple instruments with inconsistent scales and metrics. Although a more standardized approach would be desirable, the most appropriate instrument to be used in this setting is still largely undefined. The aim of the study was to assess the respective ability of two validated QoL instruments (European Organization for Research and Treatment of Cancer (EORTC) QLQ-C30/L13 and Short Form (36) Health Survey (SF-36)) to detect perioperative changes in QoL of patients submitted to pulmonary resection for non-small-cell lung cancer (NSCLC). A prospective study on 33 consecutive patients (May 2009-December 2009) was submitted to pulmonary resection. All patients completed both EORTC QLQ-C30 with lung module 13 and SF-36 pre- and postoperatively (3 months). Preoperative changes of all SF-36 and EORTC scales were assessed by using the Cohen's effect-size method. External convergence between different instruments (SF-36 vs EORTC) was assessed by measuring the correlation of scales evaluating the same concepts (physical, psychosocial, and emotional). The correlation coefficients between standardized perioperative changes (effect sizes) of objective functional parameters (forced expiratory volume in 1s (FEV1) and diffusion lung capacity for carbon monoxide (DLCO)) and SF-36 or EORTC scales were also investigated. A poor correlation (r < 0.5) was detected between most of the scales of the two instruments measuring the same QoL concepts, indicating that they may be complementary in investigating different aspects of QoL. Only the SF-36 and EORTC social functioning scales and the SF-36 mental health and EORTC emotional functioning scales had a correlation coefficient >0.5. In general, EORTC was more sensitive in detecting physical or emotional declines but was more conservative in detecting improvements. Both SF-36 and EORTC showed poor correlations (r < 0.5) between perioperative changes in QoL and FEV1 or DLCO, confirming that objective parameters cannot be surrogates to the subjective perception of QoL. In particular, there was a poor correlation between perceived changes in dyspnea and objective changes in FEV1 or DLCO. EORTC behaved similarly to SF-36 in assessing perioperative changes in generic QoL scales, but, with the use of its lung module, provided a more detailed evaluation of specific symptoms. For this reason, EORTC should be regarded as the instrument of choice for measuring QoL in the thoracic surgery setting. Copyright © 2010 European Association for Cardio-Thoracic Surgery.

The transmembrane 4 L six family proteins TM4SF1, TM4SF4, and TM4SF5 share 40-50% overall sequence identity, but their C-terminus identity is limited. It may be likely that the C-termini of the members are important and unique for own regulatory functions. We thus examined how the TM4SF5 C-terminus affected cellular functions differentially from other family members. Using colon cancer cells expressing wildtype (WT), C-terminus-deleted, or chimeric mutants, diverse cellular functions were explored in 2-dimensional (2D) and 3-dimensional (3D) condition. The C-termini of the proteins were relatively comparable with respect to 2D cell proliferation, although each C-terminal-deletion mutant exhibited increased proliferation relative to the WT. Using chimeric constructs, we found that the TM4SF5 C-terminus was critical for regulating the diverse metastatic functions of TM4SF5, and could positively replace the C-termini of other family members. Replacement of the TM4SF1 or TM4SF4 C-terminus with that of TM4SF5 increased spheroids growth, transwell migration, and invasive dissemination from spheroids in 3D collagen gels. TM4SF5-mediated effects required its extracellular loop 2 linked to the C-terminus via the transmembrane domain 4, with causing c-Src activation. Altogether, the C-terminus of TM4SF5 appears to mediate pro-migratory roles, depending on a structural relay from the second extracellular loop to the C-terminus. PMID:28129652

The purpose of this study was to determine the influence of annual income, Medicare status, and demographic variables on the health-related quality of life (HQoL) of renal transplant recipients. A cross-sectional survey was mailed to 146 Georgia renal transplant recipients who had functional grafts. Data were collected using the SF-12 Health Survey (version 2), a demographics survey, and 2003 tax documents. One-way ANOVAs and Pearson's R correlations were used to examine relationships between annual income, Medicare status, demographic variables and SF-12 scores. Significant variables were included in stepwise multiple regression analyses. Data from 130 participants (89% response rate) were collected. Recipients with no Medicare coverage had significantly higher scores on the Physical Functioning and Role Physical SF-12 scales (p = 0.005) compared to recipients with Medicare. Annual income was positively correlated with General Health (p < 0.05). Age and race were significant predictors of Vitality (p = 0.004) and Physical Component Summary (p < 0.001) scores. Age, race, and Medicare status were significant predictors of Physical Functioning and Role Physical scores (p < 0.001). Age, annual income, race, and years post-transplant were significant predictors of General Health score (p < 0.001). Age was the sole predictor of Bodily Pain score (p = 0.002), and marital status was the sole predictor of Social Functioning score (p = 0.005). Interventions designed to offset financial barriers may be needed to bolster renal transplant recipients' HQoL.

Exercise therapy is an effective component of fibromyalgia (FM) treatment. However, it is important to know the effects and specificities of the different types of exercise: muscle stretching and resistance training. To verify and compare the effectiveness of muscle stretching exercise and resistance training for symptoms and quality of life in FM patients. Randomized controlled trial. Physical therapy service, FM outpatient clinic. Forty-four women with FM (79 screened). Patients were randomly allocated into a stretching group (n=14), resistance group (n=16), and control group (n=14). Pain was assessed using the visual analog scale, pain threshold using a Fischer dolorimeter, FM symptoms using the Fibromyalgia Impact Questionnaire (FIQ), and quality of life using the Medical Outcomes Study 36-item Short- Form Health Survey (SF-36). The three intervention groups continued with usual medical treatment. In addition, the stretching and resistance groups performed two different exercise programs twice a week for 12 weeks. After treatment, the stretching group showed the highest SF-36 physical functioning score (p=0.01) and the lowest bodily pain score (p=0.01). The resistance group had the lowest FIQ depression score (p=0.02). The control group had the highest score for FIQ morning tiredness and stiffness, and the lowest score for SF-36 vitality. In clinical analyses, the stretching group had significant improvement in quality of life for all SF-36 domains, and the resistance group had significant improvement in FM symptoms and in quality of life for SF-36 domains of physical functioning, vitality, social function, emotional role, and mental health. Muscle stretching exercise was the most effective modality in improving quality of life, especially with regard to physical functioning and pain, and resistance training was the most effective modality in reducing depression. The trial included a control group and two intervention groups, both of which received exercise programs created specifically for patients with FM. In clinical practice, we suggest including both of these modalities in an exercise therapy program for FM.

To explore the psychometric performances and applicability of SF-36v2 in assessment quality of life among urban residents in Chengdu. During Oct. to Dec., 2012, 2 186 adult urban residents with clear mind and well self-express were recruited in the study by multistage stratified cluster sampling method in Chengdu urban area. The survey questionnaires included general health condition and quality of life, which was adopted the SF-36v2. Internal consistency reliability, test-retest reliability and construct validity were all analyzed as indicators of the psychometric performance. The survey released 2 186 questionnaires, with 2 182 ones returned and 2 178(99.8%) met the data standard. The scores of 8 scales in SF-36v2, including physical function (PF), role-physical (RP), bodily pain (BP), general health (GH), vitality (VT), social function (SF), role-emotion (RE) and mental health (MH), were 89.15 ± 17.56, 85.18 ± 22.52, 76.64 ± 17.80, 64.13 ± 19.56, 70.39 ± 17.31, 86.43 ± 17.35, 87.79 ± 19.24 and 80.61 ± 13.49, respectively; the floor effects were 0.28%, 0.41%, 0.23%, 0.28%, 0.09%, 0.05%, 0.14% and 0.23%, respectively; and the ceiling effects were 51.38%, 60.60%, 58.08%, 0.83%, 2.94%, 50.32%, 64.00% and 3.95%, respectively. The item-convergent validities were all achieved the standard (r = 0.40) except the item MH5 (Have you been happy?), and the total scaling success rate of item-convergent validity was 97.14%. The scales' success rates of item-discriminant validities for the SF, VT and MH scales were 93.75%, 56.25% and 97.50% respectively, while the rates of others were 100.00% and the total success rate was 96.43%. The internal reliability ranged from 0.724 to 0.974 across all the scales, except for SF (r = 0.603) and VT (r = 0.697). The two-week test-retest reliability ranged from 0.610 to 0.845. Within factor analysis, two common factors were confirmed, separately representing physical health and mental health, altogether contributing 64.4% of the total variance. As a revised version of SF-36v1, the SF-36v2 seemed to be more preferable in layout for questions and answers and could reduce the ceiling and floor effect. Additionally, it also showed comparatively well reliability and validity. And thereby we believed the SF-36v2 could be applied to assess the life quality among urban residents in Chengdu.

To study the effects of a 3-month multidisciplinary intervention based on exercise and psychological therapy on symptomatology and quality of life in women with fibromyalgia. Seventy-five women with fibromyalgia volunteered to participate and were allocated to a 3-month (3-times/week) multidisciplinary (pool, land-based and psychological session based on the Acceptance and Commitment Therapy) intervention (n=41), or to a usual care group (n=34). Sixty-five women with fibromyalgia completed the study protocol (n=33 multidisciplinary intervention, aged 51.4±7.4 years and n=32 usual care group, aged 50.0±7.3 years). The outcomes variables were Fibromyalgia Impact Questionnaire (FIQ), Short Form Health Survey 36 (SF-36), Hospital Anxiety and Depression Scale, Vanderbilt Pain Management Inventory and Rosenberg Self-Esteem Scale. We observed a significant interaction effect (group*time) for the FIQ total score, the subscales fatigue, stiffness, anxiety and depression, and the subscales of SF-36 physical role, bodily pain, vitality and social functioning. Post-hoc analysis revealed significant improvements in total score of FIQ (p<0.001), fatigue (p=0.001), stiffness (p<0.001), anxiety (p=0.011), depression (p=0.008), physical role (p=0.002), bodily pain (p<0.001), vitality (p<0.001) and social functioning (p<0.001) in the intervention group, whereas in the control group, there was a significant worsening in the subscale depression (p=0.006) and social functioning (p=0.019). A 3-month low-moderate intensity multidisciplinary intervention improved fibromyalgia symptomatology and quality of life in women with fibromyalgia.

Velanovich, Vic

Gastroparesis can be a difficult problem with patients suffering from nausea, vomiting, bloating, and pain intractable to medical management. Gastric neurostimulation has been developed as an adjunctive treatment for patients with diabetic and idiopathic gastroparesis unresponsive to pharmacologic and dietary treatment. The purpose of this study is to report symptomatic and quality-of-life response to gastric neurostimulation. This study was approved by the institutional review board, and patients had informed consent. The gastric neurostimulation device (Enterra therapy, Medtronic, Inc., Minneapolis, MN, USA) is approved by the Food and Drug Administration under the Humanitarian Device Exemption. Candidates for placement were patients with either idiopathic or diabetic gastroparesis who had symptomatic failure to dietary changes and to prokinetic and antiemetic drugs. Before placement, the patients' symptoms were recorded, and patients completed the Gastrointestinal Symptom Rating Scale (GSRS, three domains: dyspeptic syndrome, indigestion syndrome, and bowel dysfunction syndrome) and the Short Form-36 (SF-36, eight domains: physical functioning, role-physical, role-emotional, bodily pain, vitality, mental health, social functioning, general health, plus a health transition item). The device was surgically placed using a hybrid laparoscopic/open technique. Patients were followed and adjustments made on the device until satisfactory symptom control was achieved. At that time, patients completed both the GSRS and SF-36, and comparisons were made to preoperative values. Forty-two patients had the device placed, 29 women, aged 41 (SD +14) years, 24 diabetic patients, 17 idiopathic patients, one postgastrectomy patient. Median follow-up was 12 months (range 1-42 months). There was a 2% immediate postoperative morbidity rate and 7% long-term morbidity rate (device extrusion). Thirty-one patients (74%) responded to gastric neurostimulation of variable degrees. Eleven patients had no response or had worsening symptoms. Of the patients who responded, there were statistically significant improvements in all three domains of the GSRS. Median scores (with interquartile ranges): dyspeptic syndrome, 9 (7-11.5) to 4 (2.5-6), p = 0.02; indigestion syndrome, 5 (2-7) to 4 (0-5), p = 0.05; bowel dysfunction syndrome, 3 (2-3) to 1 (0-1), p = 0.01. In the SF-36, there were statistically significant improvement in the health transition item, 4 (4-5) to 1.5 (1-3), p = 0.01; and social functioning domain, 25 (12.5-62.5) to 75 (50-87.5), p = 0.03. Three quarters of gastroparesis patients responded to gastric neurostimulation to variable degrees. Gastrointestinal-specific symptoms are improved in responders. Patients felt that there health and social functioning (SF) improved, although there was no significant difference in the other domains. These results are encouraging considering that these patients had intractable symptoms with no other effective treatments available.

Sensory hyperreactivity (SHR) is one explanation for airway symptoms induced by chemicals and scents. Little is known about health-related quality of life (HRQOL) and coping, in this group of patients. A study was done in patients with SHR to (1) compare the Nottingham Health Profile (NHP) and the Short-Form 36 Health Survey (SF-36) in regard to their suitability, validity, reliability, and acceptability; (2) evaluate how the patients cope with the illness; (3) assess whether there are differences between women and men with respect to HRQOL and coping; and (4) assess whether there are differences between patients and normative data with respect to HRQOL and coping. A total of 115 patients (91 women) with SHR were asked to answer five questionnaires: a study-specific questionnaire, the Chemical Sensitivity Scale for Sensory Hyperreactivity (CSS-SHR), the NHP, the SF-36, and the Jalowiec Coping Scale-60. Eighty-three patients (72%; 70 women) completed all questionnaires. The SF-36 scores were less skewed and more homogeneously distributed and showed fewer floor and ceiling effects than the NHP scores. The SF-36 was also discriminated better between patients with high and low CSS-SHR scores. The reliability standard for both questionnaires was satisfactory. There were no gender differences in HRQOL. Patients with SHR had significantly lower HRQOL scores than the normative data in comparable domains of the NHP and the SF-36: emotional reactions/mental health, energy/vitality, physical mobility/functioning, and pain/bodily pain. In social isolation/functioning, the results were different; the NHP scores were similar to the normative data and the SF-36 scores were lower. The most commonly used coping styles were optimistic, self-reliant, and confrontational. Women used optimistic coping more than men. Compared with the normative group, patients with SHR used confrontational and optimistic coping more and emotive coping less. The current findings showed that both the NHP and the SF-36 were reliable instruments; but the results suggest that the SF-36 is a more sensitive instrument than the NHP for elucidating HRQOL in patients with SHR. Patients with SHR experienced a poor HRQOL and they followed the Western tradition of preferring problem-focused coping strategies to palliative and emotive strategies.

Women with premature ovarian failure (POF) often manifest complaints involving different aspects of sexual function (SF), regardless of using hormone therapy. SF involves a complex interaction between physical, psychological, and sociocultural aspects. There are doubts about the impact of different complaints on the global context of SF of women with POF. To evaluate the percentage of influence of each of the sexuality domains on the SF in women with POF. Cross-sectional study with 80 women with POF, matched by age to 80 women with normal gonadal function. We evaluated SF through the "Female Sexual Function Index" (FSFI), a comparison between the POF and control groups using the Mann-Whitney test. Component exploratory factor analysis was used to assess the proportional influence of each domain on the composition of the overall SF for women in the POF group. SF was evaluated using FSFI. Exploratory Factor Analysis for components was used to evaluate the role of each domain on the SF of women with POF. The FSFI score was significantly worse for women with POF, with a decrease in arousal, lubrication, orgasm, satisfaction, and dyspareunia. Exploratory factor analysis of SF showed that the domain with greater influence in the SF was arousal, followed by desire, together accounting for 41% of the FSFI. The domains with less influence were dyspareunia and lubrication, which together accounted for 25% of the FSFI. Women with POF have impaired SF, determined mainly by changes in arousal and desire. Aspects related to lubrication and dyspareunia complaints have lower determination coefficient in SF. These results are important in adapting the approach of sexual disorders in this group of women. © 2014 International Society for Sexual Medicine.

Cardiopulmonary exercise training is beneficial to people with coronary artery disease (CAD). Nevertheless, the correlation between aerobic capacity, and functional mobility and quality of life in elderly CAD patients is less addressed. The purpose of the current study is to investigate the beneficial effects of exercise training in elderly people with CAD, integrating exercise stress testing, functional mobility, handgrip strength, and health-related quality of life. Elderly people with CAD were enrolled from the outpatient clinic of a cardiac rehabilitation unit in a medical center. Participants were assigned to the exercise training group (N = 21) or the usual care group (N = 15). A total of 36 sessions of exercise training, completed in 12 weeks, was prescribed. Echocardiography, exercise stress testing, the 6-minute walking test, Timed Up and Go test, and handgrip strength testing were performed, and the Short-Form 36 questionnaire (SF-36) was administered at baseline and at 12-week follow-up. Peak oxygen consumption improved significantly after training. The heart rate recovery improved from 13.90/minute to 16.62/minute after exercise training. Functional mobility and handgrip strength also improved after training. Significant improvements were found in SF-36 physical function, social function, role limitation due to emotional problems, and mental health domains. A significant correlation between dynamic cardiopulmonary exercise testing parameters, the 6-minute walking test, Timed Up and Go test, handgrip strength, and SF-36 physical function and general health domains was also detected. Twelve-week, 36-session exercise training, including moderate-intensity cardiopulmonary exercise training, strengthening exercise, and balance training, is beneficial to elderly patients with CAD, and cardiopulmonary exercise testing parameters correlate well with balance and quality of life.

Benzodiazepines (BZD) are among the most widely prescribed drugs in developed countries. Since BZD can produce tolerance and dependence even in a short time, their use is recommended for a very limited time. However, these recommendations have been largely disregarded. The chronic use of BZD causes a number of serious side effects, i.e., cognitive impairment, falls, traffic accidents, dependence and tolerance. The aim of the present study was to evaluate quality of life (QoL) in a cohort of 62 consecutive high-dose BZD-dependent patients seeking a BZD detoxification. Patients seeking BZD detoxification were evaluated using the General Health Questionnaire (GHQ-12) and the short form-36 questionnaire (SF-36). Patients showed a significant reduction of QoL as measured by either SF-36 or GHQ-12. In particular, the greater impairment was observed in the items exploring physical and emotional status. Physical functioning was the item more influenced by the length of BZD abuse. Female patients showed a greater reduction of QoL compared to male, at least in some of the explored items. Social functioning scores were greatly reduced. The present study shows for the first time that high-doses BZD dependent patients have a reduced QoL and a reduced social functioning, along with high levels of psychological distress.

The aim of the present prospective and descriptive study was to assess the impact of facial aesthetic and reconstructive surgeries on quality of life. Ninety-one patients, of whom 43 had aesthetic surgery and 48 had reconstructive surgery, were analysed. The data were collected using the patient information form, body cathexis scale, and short form (SF)-36 quality of life scale. There were significant differences between before and after the surgery in both groups in terms of body cathexis scale and quality of life (p < 0.05 for both). It was observed that problems regarding the body image perception were encountered more, and the quality of life was poorer in both aesthetic and reconstructive surgery patients before the surgery. However, the problems were decreased, and the quality of life was enhanced after the surgery. Among the parameters of SF-36 quality of life scale, particularly the mean scores of social functioning, physical role functioning, emotional role functioning, mental health, and vitality/fatigue were found low before the surgery, whereas the mean scores were significantly improved after the surgery. The results revealed that facial aesthetic and reconstructive surgical interventions favourably affected the body image perception and self-esteem and that positive reflections in emotional, social, and mental aspects were effective in enhancing self-confidence and quality of life of the individual.

BACKGROUND/PURPOSE: To determine the relation between visual impairment, visual functioning, and the global quality of life in patients with glaucoma. METHODS: Visual impairment, defined with the American Medical Association Guides to the Evaluation of Permanent Impairment; visual functioning, measured with the VF-14 and the Field Test Version of the National Eye Institute-Visual Functioning Questionnaire (NEI-VFQ); and the global quality of life, assessed with the Medical Outcomes Study 36-Item Short Form Health Survey (SF-36), were determined in 147 consecutive patients with glaucoma. RESULTS: None of the SF-36 domains demonstrated more than a weak correlation with visual impairment. The VF-14 scores were moderately correlated with visual impairment. Of the twelve NEI-VFQ scales, distance activities and vision specific dependency were moderately correlated with visual impairment. Of the twelve NEI-VFQ scales, distance activities and vision specific dependency were moderately correlated with visual field impairment; vision specific social functioning, near activities, vision specific role difficulties, general vision, vision specific mental health, color vision, and driving were modestly correlated; visual pain was weakly correlated; and two were not significantly correlated. Correcting for visual actuity weakened the strength of the correlation coefficients. CONCLUSIONS: The SF-36 is unlikely to be useful in determining visual impairment in patients with glaucoma. Based on the moderate correlation between visual field impairment and the VF-14 score, this questionnaire may be generalizable to patients with glaucoma. Several of the NEI-VFQ scales correlate with visual field impairment scores in patients with a wide range of glaucomatous damage. PMID:8981717

Background Weather is a potentially important determinant of physical activity. Little work has been done examining the relationship between weather and physical activity, and potential modifiers of any relationship in older people. We therefore examined the relationship between weather and physical activity in a cohort of older community-dwelling people. Methods We analysed prospectively collected cross-sectional activity data from community-dwelling people aged 65 and over in the Physical Activity Cohort Scotland. We correlated seven day triaxial accelerometry data with daily weather data (temperature, day length, sunshine, snow, rain), and a series of potential effect modifiers were tested in mixed models: environmental variables (urban vs rural dwelling, percentage of green space), psychological variables (anxiety, depression, perceived behavioural control), social variables (number of close contacts) and health status measured using the SF-36 questionnaire. Results 547 participants, mean age 78.5 years, were included in this analysis. Higher minimum daily temperature and longer day length were associated with higher activity levels; these associations remained robust to adjustment for other significant associates of activity: age, perceived behavioural control, number of social contacts and physical function. Of the potential effect modifier variables, only urban vs rural dwelling and the SF-36 measure of social functioning enhanced the association between day length and activity; no variable modified the association between minimum temperature and activity. Conclusions In older community dwelling people, minimum temperature and day length were associated with objectively measured activity. There was little evidence for moderation of these associations through potentially modifiable health, environmental, social or psychological variables. PMID:24497925

The Glasgow Outcome Scale Extended (GOSE) is the established functional outcome scale to assess disability following traumatic brain injury (TBI), however does not capture the patient's subjective perspective. Health-related quality of life (HRQL) does capture the individual's perception of disability after TBI, and has therefore been recognized as an important outcome in TBI. In contrast to GOSE, HRQL enables comparison of health outcome across various disease states and with healthy individuals. We aimed to assess functional outcome, HRQL, recovery, and predictors of 6 and 12-month outcome in a comprehensive sample of patients with mild, moderate or severe TBI, and to examine the relationship between functional impairment (GOSE) and HRQL. A prospective cohort study was conducted among a sample of 2066 adult TBI patients who attended the emergency department (ED). GOSE was determined through questionnaires or structured interviews. Questionnaires 6 and 12 months after ED treatment included socio-demographic information and HRQL measured with Short-Form Health Survey (SF-36; reflecting physical, mental and social functioning) and Perceived Quality of Life Scale (PQoL; measuring degree of satisfaction with functioning). 996 TBI survivors with mild, moderate or severe TBI completed the 6-month questionnaire. Functional outcome and HRQL after moderate or severe TBI was significantly lower than after mild TBI. Patients with moderate TBI showed greatest improvement. After one year, the mild TBI group reached outcomes comparable to population norms. TBI of all severities highly affected SF-36 domains physical and social functioning, and physical and emotional role functioning. GOSE scores were highly related to all SF-36 domains and PQoL scores. Female gender, older age, co-morbidity and high ISS were strongest independent predictors of decreased HRQL at 6 and 12 months after TBI. HRQL and recovery patterns differ for mild, moderate and severe TBI. This study indicates that GOSE, although clinically relevant, fails to capture the subjective perspective of TBI patients, which endorses the use of HRQL as valuable addition to established instruments in assessing disability following TBI. Influence of TBI severity on recovery, together with female gender, older age, co-morbidity and high ISS should be considered in long-term follow-up and intervention programs.

Considering the importance of sport activity for enhancing quality of life, the aim of this study was to investigate the effects of regular sport activity on quality of life of kidney transplant recipients. Health-related quality of life (HRQoL) was assessed with the use of the SF-36 questionnaire on a group of 118 active kidney transplant patients (AKTPs) practicing different sports at low to moderate intensity (5±4 h/wk). Scores were compared with those of 79 sedentary kidney transplant patients (SKTPs) and with 120 active healthy control subjects (AHCs). AKTPs reported higher scores than SKTPs in the SF-36 scales of Physical Functioning (P<.05), Role Limitations due to Physical Problems (P<.05), General Health (P<.01), Vitality (P<.05), Social Functioning (P<.05), Role Limitations due to Emotional Problems (P<.05), and Mental Health (P<.01). AKTPs obtained higher scores than AHCs on the Mental Health (P<.01) and Social Functioning scales (P<.01) and similar scores (P>.05) on all the other scales. The effect of quantity of sport activity was significant on the General Health (P<.01; η2=0.05), and Role Physical scales (P=.04; η2=0.03), with higher sport activity associated with higher HRQoL. The effect of sex was significant for Bodily Pain (P=.05; η2=0.02), Vitality (P=.08; η2=0.06), Social Functioning (P=.08; η2=0.05), and Mental Health (P=.05; η2=0.02), with male participants scoring higher than female participants. This study indicates that regular sport activity significantly improves different dimensions of HRQoL among kidney transplant recipients. The benefits of sport activity go beyond its impact on physical health to involve psychologic and social components of quality of life. Spontaneous and low to moderate sport activity may play an important role after kidney transplantation that has been largely underestimated in the literature. Copyright © 2014 Elsevier Inc.

This study assessed the extent to which alcohol consumption in a military group differed from the general population, and how alcohol affected the military group's health and social functioning. A cross sectional survey of military personnel (n = 5311) collected self-reported data on alcohol use (AUDIT scale) and general health, role limitations because of physical health problems (role physical), and social functioning scores (SF36 subscales). Logistic regression was used to compare drinking behaviours between the military sample and a general population sample, using the categories risky drinkers (>2 units per day), low risk drinkers (≤2 standard drinks per day) and abstainers. Groups in the military sample with the highest levels of alcohol misuse (harmful drinking AUDIT ≥ 16, alcohol dependence AUDIT ≥ 20, and binge drinking) were also identified. Linear regression models were then used to assess the association between alcohol misuse and SF36 scores. There were fewer risky drinkers in the military sample than in the general population sample. There were also fewer abstainers, but more people who drank at a lower risk level (≤2 standard drinks per day), than in a sample of the general population. Harmful drinking and alcohol dependence were most commonly observed in men, younger age groups, non-commissioned officers and lower ranks as well as reserve and ex-serving groups. Alcohol misuse was clearly associated with poorer general health scores, more role limitations because of physical health problems, and lower social functioning. Although risky drinking was lower in the military group than in the general population, drinking was associated with poorer health, more limitations because of physical health problems, and poorer social functioning in Defence members. These results highlight the potential benefits for Defence forces in reducing alcohol use among members, in both those groups identified at highest risk, and across the military workforce as a whole.

Background Measuring health status in a population is important for the evaluation of interventions and the prediction of health and social care needs. Quality of life (QoL) studies are an essential complement to medical evaluation but most of the tools available in this area are in English. In order to evaluated QoL in rural and urban areas in Lebanon, the short form 36 health survey (SF-36) was adapted into Arabic. Methods SF-36 was administered in a cross-sectional study, to collect sociodemographic and environmental variables as well as self reported morbidity. We analysed a representative sample containing 1632 subjects, from whom we randomly picked 524 subjects aged 14 years and over. The translation, cultural adaptation and validation of the SF-36 followed the International Quality of Life Assessment methodology. Multivariate analysis (generalized linear model) was performed to test the effect of habitat (rural on urban areas) on all domains of the SF-36. Results The rate of missing data is very low (0.23% of items). Item level validation supported the assumptions underlying Likert scoring. SF-36 scale scores showed wide variability and acceptable internal consistency (Cronbach's alpha >0.70), factor analysis yielded patterns of factor correlation comparable to that found in the U.S.A and France. Patients resident in rural areas had higher vitality scores than those in urban areas. Older people reported more satisfaction with some domains of life than younger people, except for physical functioning. The QoL of women is poorer than men; certain symptoms and morbidity independently influence the domains of SF-36 in this population. Conclusion The results support the validity of the SF-36 Arabic version. Habitat has a minor influence on QoL, women had a poor QoL, and health problems had differential impact on QoL. PMID:12952543

Transmembrane 4 L Six Family Member 5 (TM4SF5)-Mediated Epithelial-Mesenchymal Transition in Liver Diseases.

2015-01-01

The membrane protein TM4SF5, a member of the transmembrane 4L six family, forms a tetraspanin-enriched microdomain (TEM) on the cell surface, where many different membrane proteins and receptors form a massive protein-protein complex to regulate cellular functions including transdifferentiation, migration, and invasion. We recently reported that TM4SF5 causes epithelial-mesenchymal transition (EMT), eventually contributing to aberrant multilayer cellular growth, drug resistance, enhanced migration, invasion, its circulation in the blood, tumor initiation for successful metastasis, and muscle development in zebrafish. In this review, I summarize the information on the role of TM4SF5 in EMT-related functions at TM4SF5-enriched microdomain (T5EM) on cell surface, where proteins such as TM4SF5, CD151, CD44, integrins, and epidermal growth factor receptor (EGFR) can form numerous protein complexes. TM4SF5-mediated EMT contributes to diverse cellular functions, leading to fibrotic phenotypes and initiating and maintaining tumors in primary and/or metastatic regions, in addition to its role in muscle development in zebrafish. Anti-TM4SF5 strategies for addressing the protein networks can lead to regulation of the fibrotic, tumorigenic, and tumor-maintaining functions of TM4SF5-positive hepatic cells. This review is for us to (re)consider the antifibrotic or antitumorigenic (i.e., anti-EMT-related diseases) strategies of dealing with protein networks that would be involved in cross-talks to regulate various cellular functions during TM4SF5-dependent progression from fibrotic to cancerous hepatic cells.

Studies have shown that spiritual/religious beliefs are associated with mental health and health-related quality of life (HRQoL). However, few studies evaluated how spiritual/religious coping (SRC) could affect hemodialysis patients. The present study investigated the role of SRC behaviors on HRQoL and depressive symptoms in hemodialysis patients. This was cross-sectional study with 184 patients. Patients completed the Beck Depression Inventory, Brief SRC Scale, Medical Outcomes Study 36-Item Short-Form Health Survey (SF-36), and a Sociodemographic and Health Characterization Questionnaire. From 218 patients, 184 (84.4%) were included (53.8% male with a median age of 55.9 years). Negative SRC, but not positive SRC, was associated with depressive symptoms. Positive SRC presented significant effects in SF-36 pain and physical and social functioning. On the other hand, negative SRC exhibited significant effects in SF-36 role emotional, energy/fatigue, pain, and physical functioning. SRC influences the mental health and HRQoL in Brazilian hemodialysis patients in two distinct ways. If used positively, it may have positive outcomes. However, if used negatively, it may lead to dysfunctional consequences such as greater depressive symptomatology and affect HRQoL. Health professionals must be aware of these "two sides of the same coin."

To determine and compare the sensitivity to change of the condition-specific cervical Northern American Spine Society (NASS) and the generic Short Form 36 (SF-36). Prospective cohort study. One hundred and seventy five patients after whiplash injury. Four-week inpatient interdisciplinary pain management programme. MAIN MEASURES, ANALYSIS: Responsiveness of the NASS and the SF-36 was quantified by effect size and standardized response mean and compared within the same construct by the modified Jacknife test. Ability to detect improvement was compared using sensitivities determined from receiver operating characteristics curves. In pain, the NASS was comparable responsive to the SF-36 at the one-month follow-up (n = 175): effect sizes: 0.62 (NASS) versus 0.61 (SF-36), P = 0.914. The NASS was less responsive than the SF-36 in function: 0.23 versus 0.63, P < 0.001 and in pain+function: 0.35 versus 0.58 (P = 0.001). These relationships remained consistent using standardized response means, at the six-month follow-up (n = 103), and in the comparison of the sensitivities. Sensitivities at one month, pain: 70% (NASS) versus 62% (SF-36), P = 0.234; function: 65% versus 80%, P = 0.002; pain+function: 68% versus 78%, P = 0.035. The six-month data were similar. The generic SF-36 was more responsive in function and equally responsive in pain when compared to the condition-specific NASS. The SF-36 can be recommended as a responsive instrument for measurement of pain and function in chronic whiplash syndrome.

Patients with schizophrenia (SCZ) tend to sample less information when making a decision, jumping to conclusions (JTC) without sufficient evidence. This "JTC bias" may be a trait marker of the disease and may not improve with antipsychotic treatment. We conducted a double-blind, placebo-controlled trial to test whether intranasal oxytocin could reduce JTC in stable, medicated patients with SCZ and healthy controls (HCs). We also explored whether striatal volume, clinical symptoms, and baseline social functioning (SF) was related to JTC performance. Forty-three male, medicated SCZ patients (Mean Age: 40.81±11.44) and sixteen HCs (Mean Age: 30.38±9.85) participated in a double-blind, placebo-controlled, cross-over study. Participants completed the Beads Task on two separate visits (minimum 20days apart). Participants were randomized to receive either intranasal oxytocin (50IU in solution) or intranasal placebo (saline). Twenty of the SCZ patients and all sixteen HCs also provided T1 MRIs (3-T). Patients with SCZ took fewer draws to decision (DTD) than HCs (t(57)=2.78, p=0.007). Oxytocin did not significantly change DTD in patients (t(42)=-1.11, p=0.27), nor in HCs (t(15)=-0.62, p=0.55). Exploratory analyses found ventral caudate volumes were negatively correlated with DTD (r(18)=-0.50, p=0.03) in patients. Moreover, oxytocin was more likely to improve JTC in patients with lower baseline SF. However, these exploratory findings did not survive correction for multiple comparisons. We replicate increased JTC in SCZ. However, acute intranasal oxytocin did not modify JTC. Future studies with larger samples should explore how brain morphology and SF are related to JTC performance in patients with SCZ. Copyright © 2017 Elsevier Ltd. All rights reserved.

The Computerized Adaptive Test of Personality Disorder-Static Form (CAT-PD-SF) is a self-report inventory developed to assess pathological personality traits. The current study explored the reliability and higher order factor structure of the Norwegian version of the CAT-PD-SF and the relationships between the CAT-PD traits and domains of personality functioning in an undergraduate student sample ( N = 375). In addition to the CAT-PD-SF, the short form of the Severity Indices of Personality Problems and the Brief Symptom Inventory were administered. The results showed that the Norwegian CAT-PD-SF has good score reliability. Factor analysis of the CAT-PD-SF scales indicated five superordinate factors that correspond to the trait domains of the alternative DSM-5 model for personality disorders. The CAT-PD traits were highly predictive of impaired personality functioning after controlling for psychological distress. It is concluded that the CAT-PD-SF is a promising tool for the assessment of personality disorder traits.

The baculovirus Autographa californica multiple nucleopolyhedrovirus (AcMNPV) possesses a gene, ac-pcna or ac49, which encodes a protein with similarity to proliferating cell nuclear antigen (PCNA). Homologs of this gene code for DNA polymerase processivity factors and are essential in the DNA replication systems. But the function of ac-pcna still remains unclear. To define the function of Ac-pcna in AcMNPV and Sf-pcna in host Sf9 cells, Bac-to-Bac baculovirus expression system was used to generate two recombinant baculoviruses: AcMNPV-Ac-pcna-EGFP and AcMNPV-Sf-pcna-EGFP. Results indicated that AcMNPV-mediated overexpression of Ac-PCNA and Sf-PCNA could stimulate replication of AcMNPV genome in the host Sf9 cells. Meanwhile, either AcMNPV-Ac-pcna-EGFP or AcMNPV-Sf-pcna-EGFP had a significant stimulating effect on Sf9 genome replication during infection. We also found that Ac-PCNA and Sf-PCNA could promote the production of budded virus. Ac-PCNA could improve the transcription level of ie2 gene dramatically and further improved the transcription of late gene, for example 38 K and vp39, at 12 h p.i.. Moreover, insecticidal potency test showed that the larvae of Beet armyworm in the AcMNPV-Ac-pcna-EGFP and AcMNPV-Sf-pcna-EGFP groups had a higher mortality rate (83.33 and 91.67%), a lower pupation rate (16.67 and 8.33%), and a lower emergence rate (6.67 and 3.33%), compared with those in AcMNPV-EGFP group. The function of Ac-PCNA and Sf-PCNA was confirmed in this study, which provided the theoretical foundation for using and modifying AcMNPV.

Sf9, a cell line derived from Spodoptera frugiperda, is an ideal model organism for studying insect apoptosis. The first notable study that attempted to identify the apoptotic pathway in Sf9 was performed in 1997 and included the discovery of Sf-caspase-1, an effector caspase of Sf9. However, it was not until 2013 that the first initiator caspase in Sf9, SfDronc, was discovered, and the apoptotic pathway in Sf9 became clearer. In this study, we report another caspase of Sf9, SfDredd. SfDredd is highly similar to insect initiator caspase Dredd homologs. Experimentally, recombinant SfDredd underwent autocleavage and exhibited different efficiencies in cleavage of synthetic caspase substrates. This was attributed to its caspase activity for the predicted active site mutation blocked the above autocleavage and synthetic caspase substrates cleavage activity. SfDredd was capable of not only cleaving Sf-caspase-1 in vitro but also cleaving Sf-caspase-1 and inducing apoptosis when it was co-expressed with Sf-caspase-1 in Sf9 cells. The protein level of SfDredd was increased when Sf9 cells were treated by Actinomycin D, whereas silencing of SfDredd reduced apoptosis and Sf-caspase-1 cleavage induced by Actinomycin D treatment. These results clearly indicate that SfDredd functioned as an apoptotic initiator caspase. Apoptosis induced in Sf9 cells by overexpression of SfDredd alone was not as obvious as that induced by SfDronc alone, and the cleavage sites of Sf-caspase-1 for SfDredd and SfDronc are different. In addition, despite sharing a sequence homology with initiator caspases and possessing weak activity on initiator caspase substrates, SfDredd showed strong activity on effector caspase substrates, making it the only insect caspase reported so far functioning similar to human caspase-2 in this aspect. We believe that the discovery of SfDredd, and its different properties from SfDronc, will improve the understanding of apoptosis pathway in Sf9 cells. PMID:26977926

We sought to evaluate the long term health-related quality of life (HRQOL) in patients survived severely extensive burn and identify their clinical predicting factors correlated with HRQOL. A cross-sectional study was conducted in 20 patients survived more than 2 years with extensive burn involving ≥70% total body surface area (TBSA) between 1997 and 2009 in a burn center in Shanghai. Short Form-36 Medical Outcomes Survey (SF-36), Brief Version of Burn Specific Health Scale (BSHS-B) and Michigan Hand Outcome Questionnaire (MHQ) were used for the present evaluation. SF-36 scores were compared with a healthy Chinese population, and linear correlation analysis was performed to screen the clinical relating factors predicting physical and mental component summary (PCS and MCS) scores from SF-36. HRQOL scores from SF-36 were significantly lower in the domains of physical functioning, role limitations due to physical problems, pain, social functioning and role limitations due to emotional problems compared with population norms. Multiple linear regression analysis demonstrated that only return to work (RTW) predicted improved PCS. While age at injury, facial burns, skin grafting and length of hospital stay were correlated with MCS. Work, body image and heat sensitivity obtained the lowest BSHS-B scores in all 9 domains. Improvements of HRQOL could still be seen in BSHS-B scores in domains of simple abilities, hand function, work and affect even after a quite long interval between burns and testing. Hand function of extensive burn patients obtained relatively poor MHQ scores, especially in those without RTW. Patients with extensive burns have a poorer quality of life compared with that of general population. Relatively poor physical and psychological problems still exist even after a long period. Meanwhile, a trend of gradual improvements was noted. This information will aid clinicians in decision-making of comprehensive systematic regimens for long term rehabilitation and psychosocial treatment. Copyright © 2011 Elsevier Ltd and ISBI.

The fusion of the pelvic joints in patients with severe pelvic girdle pain (PGP) is a controversial and insufficiently studied procedure. The aims of this study were to evaluate physical function and pain after sacroiliac joint (SIJ) fusion. A single-subject research design study with repeated measurements was conducted; pre-operatively and at 3, 6 and 12 months post-operatively. The outcome measures considered were the Oswestry disability index (ODI), visual analogue scale (VAS), and SF-36. Eight patients with severe PGP received open-accessed unilateral anterior SIJ fusion and fusion of the pubic symphysis. Seven patients reported positive results from the surgery. At 1 year post-operation, significant (p < 0.001) reductions in ODI (54 to 37) and VAS (82 to 57) were reported. The physical functioning, bodily pain, and social functioning scores in the SF-36 were also improved. Positive and significant changes in disability and pain at 1 year after SIJ fusion were observed. Despite these positive results, open accessed anterior fusion of the SIJ was associated with adverse events and complications such as infection and nerve damage.

The purpose of this study was to examine the prevalence of voice disorders in college students and their effect on the students as shown by quality-of-life indicators. A cross-sectional survey was completed by 545 college students in 2012. The survey included 10 questions from the Voice-Related Quality of Life (V-RQOL), selected voice symptoms, and quality-of-life indicators of functional health and well-being based on the Short Form 36-item Health Survey (SF-36). Twenty-nine percent of the college students (mean age, 22.7 years) reported a history of a voice disorder. Hoarseness was the most prevalent voice symptom, but was not correlated with V-RQOL scores. A wobbly or shaky voice, throat dryness, vocal fatigue, and vocal effort explained a significant amount of variance on the social-emotional and physical domains of the V-RQOL index (p < 0.05). Voice symptoms limited emotional and physical functioning as indicated by SF-36 scores. Voice disorders significantly influence psychosocial and physical functioning in college students. These findings have important implications for voice-care services in this population.

The orphan nuclear receptor steroidogenic factor 1 (SF-1) regulates the differentiation and function of endocrine glands. Although SF-1 is constitutively active in cell-based assays, it is not known whether this transcriptional activity is modulated by ligands. Here, we describe the 1.5 {angstrom} crystal structure of the SF-1 ligand binding domain in complex with an LXXLL motif from a coregulator protein. The structure reveals the presence of a phospholipid ligand in a surprisingly large pocket ({approx}1600 {angstrom}{sup 3}), with the receptor adopting the canonical active conformation. The bound phospholipid is readily exchanged and modulates SF-1 interactions with coactivators. Mutations designed tomore » reduce the size of the SF-1 pocket or to disrupt hydrogen bonds with the phospholipid abolish SF-1/coactivator interactions and significantly reduce SF-1 transcriptional activity. These findings provide evidence that SF-1 is regulated by endogenous ligands and suggest an unexpected relationship between phospholipids and endocrine development and function.« less

Background. There is very little data describing the long-term health impacts of meditation. Aim. To compare the quality of life and functional health of long-term meditators to that of the normative population in Australia. Method. Using the SF-36 questionnaire and a Meditation Lifestyle Survey, we sampled 343 long-term Australian Sahaja Yoga meditation practitioners and compared their scores to those of the normative Australian population. Results. Six SF-36 subscales (bodily pain, general health, mental health, role limitation—emotional, social functioning, and vitality) were significantly better in meditators compared to the national norms whereas two of the subscales (role limitation—physical, physical functioning) were not significantly different. A substantial correlation between frequency of mental silence experience and the vitality, general health, and especially mental health subscales (P < 0.005) was found. Conclusion. Long-term practitioners of Sahaja yoga meditation experience better functional health, especially mental health, compared to the general population. A relationship between functional health, especially mental health, and the frequency of meditative experience (mental silence) exists that may be causal. Evidence for the potential role of this definition of meditation in enhancing quality of life, functional health and wellbeing is growing. Implications for primary mental health prevention are discussed. PMID:22611427

For assessing influence of social factors on life quality of workers in coal extraction enterpirses of Kemerovo region, the authors used questionnaire SF-36. Life quality parameters of workers engaged into coal extraction in Kemerovo region appeared to lower with age from 20 to 64 years. Life quality parameters on scales of pain, physical functioning and general health are invertedly correlated with age and length of service in hazardous work conditions for coal extraction workers. Life quality of the miners is influenced by the following factors: marital status, educational level and income level of the workers.

The effects of the enforcement of a smoke-free workplace policy on health-related quality of life (HRQOL) among a healthy population are poorly understood. The present study was undertaken to examine the effects of the enforcement of a smoke-free school policy on HRQOL among healthy non-smoking schoolteachers with respect to their exposure to passive smoke. Two self-reported questionnaire surveys were conducted, the first before and the second after the enforcement of a total smoke-free public school policy in Nara City. A total of 1534 teachers were invited from 62 schools, and their HRQOL was assessed using six domains extracted from the Medical Outcomes Survey Short Form-8 questionnaire (SF-8): general health perception (GH), role functioning-physical (RP), vitality (VT), social functioning (SF), mental health (MH), and role functioning-emotional (RE). The participants were divided into two groups according to their exposure to environmental tobacco smoke (ETS) at baseline: participants not exposed to ETS at school (non-smokers), and participants exposed to ETS at school (passive smokers). Changes in each SF-8 score were evaluated using paired t-tests for each group, and their inter-group differences were evaluated using multiple linear regression analyses adjusted for sex, age, school type, managerial position, and attitude towards a smoke-free policy. After ineligible subjects were excluded, 689 teachers were included in the analyses. The number of non-smokers and passive smokers was 447 and 242, respectively. Significant changes in SF-8 scores were observed for MH (0.9; 95% confidence interval [CI], 0.2-1.5) and RE (0.7; 95% CI, 0.0-1.3) in non-smokers, and GH (2.2; 95% CI, 1.2-3.1), VT (1.8; 95% CI, 0.9-2.7), SF (2.7; 95% CI, 1.6-3.8), MH (2.0; 95% CI, 1.0-2.9), and RE (2.0; 95% CI, 1.2-2.8) in passive smokers. In the multiple linear regression analyses, the net changes in the category scores of GH (1.8; 95% CI, 0.7-2.9), VT (1.4, 95% CI, 0.3-2.5), SF (2.5; 95% CI, 1.1-3.9), MH (1.2; 95% CI, 0.1-2.4) and RE (1.6; 95% CI, 0.5-2.7) in passive smokers significantly exceeded those in non-smokers. A smoke-free school policy would improve the HRQOL of healthy non-smoking teachers who are exposed to ETS.

This study aimed to examine the role of social support and depression in predicting the quality of life among the elderly living in a rural Federal Land Development Authority (FELDA) community in Malaysia. A total of 162 elderly settlers of FELDA Sungai Tengi, aged 60 years and above, were selected by universal sampling method in this cross-sectional study. Three standardized instruments - the 12-item Short Form (SF-12), 15-item Geriatric Depression Scale (GDS-15) and Medical Outcome Study Social Support (MOS-Social Support) - were used to assess for quality of life, depression and social support. Quality of life of the elderly people in this community was high, especially in terms of physical components as compared to mental components. The mean scores for emotional role in the SF-12 was relatively the highest (90.74 ± 21.59) with social functioning being the lowest (30.35 ± 22.29). The results also showed that the mean value was higher for physical component summary (74.40) as compared to mental component summary (51.51). Approximately 23.5% suffered mild depression and only 2.5% had severe depression. This study showed that the elderly FELDA settlers have a high quality of life, mainly on the physical components of life and low rate of severe depression, a positive indicator of their psychological well-being. Social support in the form of emotional/informational support, and depression were significant factors related to their good quality of life. Copyright © 2013 Wiley Publishing Asia Pty Ltd.

Nausea and vomiting are troublesome symptoms occurring in the first trimester of pregnancy. The aim of this study was to describe the impact these symptoms have on women in early pregnancy by interviewing, using a structured questionnaire, 593 pregnant women presenting with nausea and vomiting in the first trimester of pregnancy. The women were asked to complete the Rhodes index of nausea and vomiting and the MOS 36 Short Form Health Survey (SF-36). Symptoms of nausea and vomiting started early in pregnancy. Nausea was the most troublesome symptom experienced by women, both in its duration and intensity. Low scores for the SF-36 were found for all items, particularly physical functioning, energy and social functioning. The women described substantial effects on working, household duties and parenting activities. Findings from this study suggest nausea and vomiting in early pregnancy has a profound impact on women's general sense of well-being and day to day life activities.

Although a score of less than 7 for the 17-item Hamilton Depression Rating Scale (HAM-D17) has been widely adopted to define remission of depression, a full recovery from depression is closely related to the patient's quality of life as well. Accordingly, we re-evaluated this definition of remission using HAM-D17 in comparison with the corresponding score for health-related quality of life (HRQOL) measured by the SF-36. Using the data for depressive patients reported by GlaxoSmithKline K.K. (Study No. BRL29060A/863) in a post-marketing observational study of paroxetine, with a sample size of n = 722, multivariate logistic regression was performed with the HAM-D17 score as a dependent variable and with each of the eight domain scores of HRQOL (from the SF-36) transformed into a binominal form according to the national standard value for Japan. Then, area under curve of receiver operating characteristic analyses were conducted. Based on the obtained results, a multivariate analysis was performed using the HAM-D17 score in a binomial form with HAM-D17 as a dependent variable and with each of the eight HRQOL domain scores (SF-36) as binominalized independent variables. A cutoff value for the HAM-D17 score of 5 provided the maximum ROC-AUC at "0.864." The significantly associated scores of the eight HRQOL domains (SF-36) were identified for the HAM-D17 cutoff values of ≥5 and ≤4. The scores for physical functioning (odds ratio, 0.473), bodily pain (0.557), vitality (0.379), social functioning (0.540), role-emotion (0.265), and mental health (0.467) had a significant negative association with the HAM-D17 score (p < 0.05), and HRQOL domain scores for HAM-D17 ≥ 5 were significantly lower compared with those for HAM-D17 ≤ 4. A cutoff value for HAM-D17 of less than or equal to 4 was the best candidate for indicating remission of depression when the recovery of HRQOL is considered. Restoration of social function and performance should be considered equally important in assessing the adequacy of treatment for patients with depression.

Familial Mediterranean fever is an auto-inflammatory disorder. Long term complications of the disease include decreased quality of life. The measurement of quality of life in the patients with chronic disease has become an important research topic during the last years. We aimed to evaluate life quality of the FMF patients by SF-36, and examine its relationship with the disease parameters. One hundred voluntary patients (69 female, 31 male) admitted to the rheumatology clinic were included in the study. The control group consisted of 100 healthy individuals. All subjects in the study were asked to complete SF-36 questionnaire. Age of onset of FMF, age at diagnosis, age at the beginning of colchicine therapy, number of attacks per month, family history of FMF and dialysis were inquired of patients with FMF. Disease severity was determined using the FMF severity score. The mean age of the patient group was 31±12 and that of the control group was 29±9. Sixty-nine patients (69%) were female, and 31 patients were male (31%) in both groups. The mean scores of the physical function, physical role function, emotional role function, mental health, and general health parameters of the patients were statistically significantly lower than those of healthy volunteers (p < 0.05). The difference in social function and vitality between two groups was found to be insignificant (p > 0.05). We have shown that FMF had a negative impact on SF-36. FMF reduces quality of life both in physical and mental dimensions.

The purpose of this study is to assess if diagnosis of type 2 diabetes affected health-related quality of life (HRQoL) among participants in the Diabetes Prevention Program/Diabetes Prevention Program Outcome Study and changes with treatment or diabetes duration. 3,210 participants with pre-diabetes were randomized to metformin (MET), intensive lifestyle intervention (ILS), or placebo (PLB). HRQoL was assessed using the SF-36 including: (1) 8 SF-36 subscales; (2) the physical component (PCS) and mental component summary (MCS) scores; and (3) the SF-6D. The sample was categorized by diabetes free versus diagnosed. For diagnosed subgroup, mean scores in the diabetes-free period, at 6 months, 2, 4 and 6 years post-diagnosis, were compared. PCS and SF-6D scores declined in all participants in all treatment arms (P < .001). MCS scores did not change significantly in any treatment arm regardless of diagnosis. ILS participants reported a greater decrease in PCS scores at 6 months post-diagnosis (P < .001) and a more rapid decline immediately post-diagnosis in SF-6D scores (P = .003) than the MET or PLB arms. ILS participants reported a significant decrease in the social functioning subscale at 6 months (P < .001) and two years (P < .001) post-diagnosis. Participants reported a decline in measures of overall health state (SF-6D) and overall physical HRQoL, whether or not they were diagnosed with diabetes during the study. There was no change in overall mental HRQoL. Participants in the ILS arm with diabetes reported a more significant decline in some HRQoL measures than those in the MET and PLB arms that developed diabetes.

ILS participants reported a greater decrease in PCS scores at 6 months post-diagnosis (P <.001) and a more rapid decline immediately post-diagnosis in SF-6D scores (P = .003) than the MET or PLB arms. ILS participants reported a significant decrease in the social functioning subscale at 6 months (P <.001) and two years (P <.001) post-diagnosis. Conclusions Participants reported a decline in measures of overall health state (SF-6D) and overall physical HRQoL, whether or not they were diagnosed with diabetes during the study. There was no change in overall mental HRQoL. Participants in the ILS arm with diabetes reported a more significant decline in some HRQoL measures than those in the MET and PLB arms that developed diabetes. PMID:23709097

Ankylosing Spondylarthritis (AS) involves by its frequency and its repercussion on the functional capacity an important handicap and deterioration of the patients quality of life. To evaluate the handicap and the quality of life during the AS and to seek the predictive factors of the deterioration of this quality of life. A prospective study relating to 50 patients recruited in the Department of Rheumatology of F. B. Hospital of Monastir during 6 months period (Mars to September 2008). The studied parameters were the quality of life evaluated by a specific sore (ASQOL) and a generic score (SF-12). Also the physical, social and economic felt handicap was evaluated using a qualitative scale. Predictive factors (clinical, biological and radiological) of the quality of life were carried out. Our patients are divided in 42 men and 8 women with an average age of 38.9 ± 10.7 years. The average duration of AS is of 11.9 ± 7.6 years. The average of ASQOL is of 11.9 ± 4 (extremes: 0- 17). The average of physical SF12 is of 29.8 ± 6 (21.7-53.2) and of mental SF-12 of 35.3 ± 6.6 (22.5-55.8). The physical, social and economic felt handicap was considered to be average or important in respectively 88%, 72% and 86% of the cases. The predictive factors of a high ASQOL (faded quality of life) are absence of occupation, high BASMI, a high number of painful articulations and high BASFI, BASDAI, BASG, BASRI and EVA total pain. The factors associated to the alteration of the quality of life according to SF-12'S are male sex, professional statute, high number of painful articulations and high BASDAI, BASFI and BASRI. Our study shows the important deterioration of the quality of life in AS patients. The existence of the predictive factors of quality of life primarily related to the functional capacity of the patients and to the disease activity implicates an early and adequate disease management in order to decrease this repercussion.

To explore the quality of life in patients treated medically during the acute phase of pancreatitis as well as at 2 and 12 months after discharge from the hospital. 40 patients were studied. The etiology of the pancreatitis was biliary causes in 31 patients and non-biliary causes in 9; mild disease was present in 29 patients and severe disease in 11. 30 patients completed the two surveys at 2 and 12 months after hospital discharge. The SF-12 and EORTC QLQ-C30 questionnaires were used for the purpose of the study. The two physical and mental component summaries of SF-12, all the domains of EORTC QLQ-C30 (except for physical functioning and cognitive functioning) and some symptom scales of EORTC QLQ-C30 (fatigue, nausea/vomiting, pain, and constipation) were significantly impaired during the acute phase of pancreatitis. There was a significant improvement in the SF-12 physical component summary, and global health, role functioning, social functioning, nausea/vomiting, pain, dyspnea, and financial difficulties (EORTC QLQ-C30) at 2 months after discharge as compared to the basal evaluation. Similar results were found after 12 months except for the mental component score at 12-month evaluation, which was significantly impaired in acute pancreatitis patients in comparison to the norms. The physical functioning of the EORTC QLQ-C30 at basal evaluation was significantly impaired in patients with severe pancreatitis in comparison to patients with mild pancreatitis. Two different patterns can be recognized in the quality of life of patients with acute pancreatitis: physical impairment is immediately present followed by mental impairment which appears progressively in the follow-up period.

The aim of this study was to determine the emotional and sociodemographic characteristics of patients with ankylosing spondylitis (AS) and to investigate the impact of the disease on their social life and quality of life (QOL). This study included 101 patients with the diagnosis of AS. All patients filled in a questionnaire comprising their sociodemographic and emotional status and their self-rating on the disease and completed the 36-item Short Form Health Survey (SF-36). The impact of the disease on work status, sexuality, and family relations was measured on a Likert scale. The impact of the disease on employment, family and sexual relations, work life as well as SF-36 was investigated. Therefore, the effect of educational level, employment, social security, and sexual relations with spouse, etc. on QOL were assessed. More than half of the patients had no knowledge about the disease and half of them were not under a physician's control. Thirty-two percent of the previously working patients quit their jobs because of the disease. Quitting a job due to the disease was more frequent in the first 10 years of the disease. The most affected domains of the SF-36 were physical role power, general health, and pain. Patients unemployed due to the disease had lower SF-36 scores compared with employed ones. Unemployed patients without social insurance had lower values on SF-36 subscales (p<0.05). A higher education level had positive influences on disease impact. The level of anxiety was high and was associated with sexual relations (p<0.05). Our results show that the disease affects patients' work and social life. Work disability affects QOL. Educating the patients about the disease may play an important role in improving his/her life quality and coping with the disease. Thus, the socioeconomic burden of the disease on the person and on society can be diminished.

How infants shape their own development has puzzled developmentalists for decades. Recent models suggest that infant dispositions, particularly negative reactivity and regulation, affect outcome by determining the extent of parental effects. Here, we used a microanalytic experimental approach and proposed that infants with varying levels of negative reactivity will be differentially impacted by parent-infant synchrony in predicting physiological and behavioral regulation of increasing social stress during an experimental paradigm. One hundred and twenty-two mother-infant dyads (4-6 months) were observed in the face-to-face still face (SF) paradigm and randomly assigned to three experimental conditions: SF with touch, standard SF, and SF with arms' restraint. Mother-infant synchrony and infant negative reactivity were observed at baseline, and three mechanisms of behavior regulation were microcoded; distress, disengagement, and social regulation. Respiratory sinus arrhythmia baseline, reactivity, and recovery were quantified. Structural equation modeling provided support for our hypothesis. For physiological regulation, infants high in negative reactivity receiving high mother-infant synchrony showed greater vagal withdrawal, which in turn predicted comparable levels of vagal recovery to that of nonreactive infants. In behavioral regulation, only infants low in negative reactivity who received high synchrony were able to regulate stress by employing social engagement cues during the SF phase. Distress was reduced only among calm infants to highly synchronous mothers, and disengagement was lowest among highly reactive infants experiencing high mother-infant synchrony. Findings chart two pathways by which synchrony may bolster regulation in infants of high and low reactivity. Among low reactive infants, synchrony builds a social repertoire for handling interpersonal stress, whereas in highly reactive infants, it constructs a platform for repeated reparation of momentary interactive "failures" and reduces the natural tendency of stressed infants to disengage from source of distress. Implications for the construction of synchrony-focused interventions targeting infants of varying dispositions are discussed.

Background A systematic review was conducted to identify and characterize self-reported sexual function (SF) measures administered to women with a history of cancer. Methods Using 2009 PRISMA guidelines, we searched electronic bibliographic databases for quantitative studies published January 2008–September 2014 that used a self-reported measure of SF, or a quality of life (QOL) measure that contained at least one item pertaining to SF. Results Of 1,487 articles initially identified, 171 were retained. The studies originated in 36 different countries with 23% from U.S.-based authors. Most studies focused on women treated for breast, gynecologic, or colorectal cancer. About 70% of the articles examined SF as the primary focus; the remaining examined QOL, menopausal symptoms, or compared treatment modalities. We identified 37 measures that assessed at least one domain of SF, eight of which were dedicated SF measures developed with cancer patients. Almost one-third of the studies used EORTC QLQ modules to assess SF, and another third used the Female Sexual Function Inventory. There were few commonalities among studies, though nearly all demonstrated worse SF after cancer treatment or compared to healthy controls. Conclusions QOL measures are better suited to screening while dedicated SF questionnaires provide data for more in depth assessment. This systematic review will assist oncology clinicians and researchers in their selection of measures of SF and encourage integration of this quality of life domain in patient care. PMID:25997102

To study whether the luxury goods make older people feel in better health and whether this association is similar in higher and lower social classes. SMILE consists of a Dutch general population consisting of 2.637 men and women aged 60 years and older in 2007. The SF-36 was used to measure health-related functioning. In the lower social class, having many luxury goods was related to feeling in better physical (OR 2.06, 95% CI 1.39-3.07) and mental health (OR 1.79, 95% CI 1.21-2.64), but not in the higher social class. There might be a health benefit of keeping up appearances, snobbism, and "conspicuous consumption" in older people from lower social classes.

Although psychosocial distress has been evaluated well in cancer entities like breast or prostate cancer, its impact on melanoma patients still needs to be characterized. The objectives of this study were to (i) evaluate psychosocial distress in melanoma patients using an expert rating instrument [basic documentation for psycho-oncology short version (PO-Bado SF)]; (ii) determine associated demographic and clinical variables; and (iii) assess the acceptance of using PO-Bado SF as a routine procedure in a skin cancer unit. A cross-sectional group of 696 melanoma patients was recruited. During the routine contact, doctors assessed the patients subjective distress using PO-Bado SF. Sociodemographic data, tumour data, treatment and the course of the disease were extracted from the patients' charts. PO-Bado SF was completed in 688 of 696 (99%) participating patients, revealing a high acceptance. In 51 (7%) patients, the PO-Bado SF cut-off score indicated the potential need of psychosocial support. Patients with previous or ongoing radiotherapy, a history of major surgery due to organ metastases, younger age and shorter time since diagnosis were considered significantly more distressed than patients without these criteria. Patients were most distressed by suffering from anxiety/worries and/or tensions. In younger patients emotional variables and other problems like social or family problems were deemed more relevant while functional limitations in daily living were reasons for higher distress in older patients. PO-Bado SF is a useful, well-accepted, practical and economic screening tool to identify distressed melanoma patients. Although most melanoma patients seem to cope well with their disease, special attention should be given to young patients in the first years after initial diagnosis and to patients with advanced disease, radiotherapy and major surgery due to their disease. Combination of expert rating tools with self-report screening instruments could further characterize the specific sources of distress to optimize psychosocial support. © 2014 European Academy of Dermatology and Venereology.

The purpose of this study was to investigate the changes in selected biomechanical variables in 80-m maximal sprint runs while imposing changes in step frequency (SF) and to investigate if these adaptations differ based on gender and training level. A total of 40 athletes (10 elite men and 10 women, 10 intermediate men and 10 women) participated in this study; they were requested to perform 5 trials at maximal running speed (RS): at the self-selected frequency (SF s ) and at SF ±15% and ±30%SF s . Contact time (CT) and flight time (FT) as well as step length (SL) decreased with increasing SF, while k vert increased with it. At SF s , k leg was the lowest (a 20% decrease at ±30%SF s ), while RS was the largest (a 12% decrease at ±30%SF s ). Only small changes (1.5%) in maximal vertical force (F max ) were observed as a function of SF, but maximum leg spring compression (ΔL) was largest at SF s and decreased by about 25% at ±30%SF s . Significant differences in F max , Δy, k leg and k vert were observed as a function of skill and gender (P < 0.001). Our results indicate that RS is optimised at SF s and that, while k vert follows the changes in SF, k leg is lowest at SF s .

Severe mental disorders are associated with social distance from the general population, but there is lack of data on the stigma reported by individuals with common mental disorders. To identify the correlates and the impact of stigma among individuals with common mental disorders. Cross-sectional, household interview survey of 8796 representing the non-institutionalized adults of Belgium, France, Germany, Italy, the Netherlands and Spain. Two perceived stigma questions (embarrassment and discrimination) were asked to respondents with significant disability. Health-related quality of life measured by the SF-12, work and activity limitation and social limitation were also assessed. Among the 815 participants with a 12-month mental disorder and significant disability, 14.8% had perceived stigma. Stigma was significantly associated with low education, being married/living with someone and being unemployed. Perceived stigma was associated with decreased quality of life (SF-12 PCS score -4.65; p<0.05), higher work and role limitation and higher social limitation. Individuals with mental disorders are more likely to report stigma if they have lower education, are married, or are unemployed. Perceived stigma is associated with considerably decrease in quality of life and role functioning. Health professionals and society at large must be aware of these findings, which suggest that fighting stigma should be a public health priority.

The objective of this study was to investigate the effects of depression relief and pain relief on the improvement in daily functioning and quality of life (QOL) for depressed patients receiving a 6-week treatment of fluoxetine. A total of 131 acutely ill inpatients with major depressive disorder (MDD) were enrolled to receive 20mg of fluoxetine daily for 6 weeks. Depression severity, pain severity, daily functioning, and health-related QOL were assessed at baseline and again at week 6. Depression severity, pain severity, and daily functioning were assessed using the 17-item Hamilton Depression Rating Scale, the Short-Form 36 (SF-36) Body Pain Index, and the Work and Social Adjustment Scale. Health-related QOL was assessed by three primary domains of the SF-36, including social functioning, vitality, and general health perceptions. Pearson's correlation and structural equation modeling were used to examine relationships among the study variables. Five models were proposed. In model 1, depression relief alone improved daily functioning and QOL. In model 2, pain relief alone improved daily functioning and QOL. In model 3, depression relief, mediated by pain relief, improved daily functioning and QOL. In model 4, pain relief, mediated by depression relief, improved daily functioning and QOL. In model 5, both depression relief and pain relief improved daily functioning and QOL. One hundred and six patients completed all the measures at baseline and at week 6. Model 5 was the most fitted structural equation model (χ(2) = 8.62, df = 8, p = 0.376, GFI = 0.975, AGFI = 0.935, TLI = 0.992, CFI = 0.996, RMSEA = 0.027). Interventions which relieve depression and pain improve daily functioning and QOL among patients with MDD. The proposed model can provide quantitative estimates of improvement in treating patients with MDD. © 2013 Elsevier Inc. All rights reserved.

CUS2, a Yeast Homolog of Human Tat-SF1, Rescues Function of Misfolded U2 through an Unusual RNA Recognition Motif

PubMed Central

Yan, Dong; Perriman, Rhonda; Igel, Haller; Howe, Kenneth J.; Neville, Megan; Ares, Manuel

1998-01-01

A screen for suppressors of a U2 snRNA mutation identified CUS2, an atypical member of the RNA recognition motif (RRM) family of RNA binding proteins. CUS2 protein is associated with U2 RNA in splicing extracts and interacts with PRP11, a subunit of the conserved splicing factor SF3a. Absence of CUS2 renders certain U2 RNA folding mutants lethal, arguing that a normal activity of CUS2 is to help refold U2 into a structure favorable for its binding to SF3b and SF3a prior to spliceosome assembly. Both CUS2 function in vivo and the in vitro RNA binding activity of CUS2 are disrupted by mutation of the first RRM, suggesting that rescue of misfolded U2 involves the direct binding of CUS2. Human Tat-SF1, reported to stimulate Tat-specific, transactivating region-dependent human immunodeficiency virus transcription in vitro, is structurally similar to CUS2. Anti-Tat-SF1 antibodies coimmunoprecipitate SF3a66 (SAP62), the human homolog of PRP11, suggesting that Tat-SF1 has a parallel function in splicing in human cells. PMID:9710584

This study aimed to investigate the effect of temperament and character traits on perceived social support and quality of life in patients with epilepsy (PWE). Fifty-two PWE and 54 healthy controls were included in this study. Demographics and clinical data were recorded. Temperament and Character traits were investigated using Temperament and Character Inventory (TCI), Perceived Social Support was evaluated by Multidimensional Scale of Perceived Social Support Scale (MSPSS), and quality of life was assessed using a 36-Item Short-Form Health Survey (SF-36). Participants also completed the Hospital Anxiety Depression Scale (HADS). TCI and MSPSS scores showed no significant difference between the groups (p>0.05). Mental and physical subscales of SF-36 were significantly lower in PWE than the controls (p=0.012, p=0.020, respectively). Multiple linear regression analysis indicated that Reward Dependence and Cooperativeness were independent predictors for perceived social support, and Persistence score was an independent predictor for the physical subscale of SF-36 even after adjustment for confounding background variables (p<0.05, for all). Temperament and character traits may affect perceived social support and quality of life in PWE. Thus, an evaluation of temperament and character traits may play a significant role in preventing negative effects on perceived social support and quality of life in PWE.

Women with hirsutism have reported imparied health and health-related quality of life (HRQoL). Social support is a factor that might increase HRQoL in chronic diseases, but little is known about this association among women with hirsutism. The aim of the study was to describe social support and explore its association with HRQoL among women with hirsutism. A further aim was to compare HRQoL in women with hirsutism with a Swedish normal population. A questionnaire including socio-demographic questions, Short-Form Health Survey (SF-36), the Multidimensional Scale of Perceived Social Support (MSPSS), and a self-estimation of hairiness using the Ferriman-Gallway scale (F-G scale) was answered by 127 women with hirsutism. Multiple regression analyses showed significant associations between social support and all health dimensions in the SF-36, also after the model was adjusted for age, hairiness and body mass index. Compared to the normal Swedish population, women with hirsutism reported significantly lower HRQoL in all dimensions of the SF-36 (p < 0.01). There is a significant positive association between social support and HRQoL, demonstrating its importance for the ability to adapt to problems associated with hirsutism. As women with hirsutism reported poorer HRQoL compared to the normal population, social support may be a factor to consider in clinical practice.

Chronic liver disease secondary to hepatitis C virus (HCV) infection is a common clinical problem. HCV is likely to adversely affect the quality of life (QoL) of the patient. This effect is said to be disproportionate to the severity of the disease. The aim of our study was to evaluate QoL in HCV-positive patients focusing both on health status and subjective satisfaction. Twenty-four patients with combined HCV and alcoholic liver disease (ETOH-HCV) were enrolled in the study. We adopted two generic tools: SF-36 (a health status questionnaire) and SAT-P (a satisfaction profile) for psychological assessment of the patients. SF-36 and SAT-P scores of ETOH-HCV patients were compared with scores of 23 patients with alcoholic liver disease (ETOH). The scores obtained from the study groups were also compared with the reference scores of the healthy Italian population. Both the groups were comparable with respect to age, histological and clinical severity of liver disease (as assessed by MELD and Child Pugh scores). Patients with ETOH-HCV scored less in the vitality and role emotional status domains of the SF-36 scores and the psychological function, social function and free time domains of the satisfaction profile. These results show a significant impact of HCV infection on health status and subjective satisfaction. Copyright © 2011 S. Karger AG, Basel.

Quality of Life (QoL) is an important outcome measure in health care and pharmacological trials. The trend towards multinational clinical trials may be problematic because it is unclear as to whether, or to what extent, QoL-measures are comparable across cultures. This study compared QoL between English and German adolescents with Cystic Fibrosis (CF) and their healthy peers. The study comprised a cross-sectional design. The English subjects formed two groups; 58 adolescents with CF and 49 healthy controls. The German subjects consisted of 26 adolescents with CF and 75 healthy controls. Quality of life was measured using the English and German versions of the SF-36. Demographic (age and gender) and clinical data (FEV1% predicted and BMI) were also recorded. The English and German CF groups had similar age-adjusted lung function and body mass index. Both the English CF and control groups reported a poorer quality of life than their respective German counterparts across several domains of the SF-36. These were limitations in activities due to physical health problems and emotional difficulties, social functioning, energy and vitality and pain. The differences in quality of life between English and German adolescents with CF appear to be either culturally determined or due to idiosyncrasies in the translations of the SF-36. rather than a consequence of their disease or its management.

Interferon α (IFN-alpha) is widely used in the treatment of viral infections, including hepatitis C. Unfortunately depression is a common side effect of IFN-alpha therapy. The presence of depressive symptoms is important because they have an adverse effect on the course of the illness and reduce the quality of life and the treatment adherence. The current prospective study examines the effects of IFN-alpha on the development of depressive disorders, on cognitive functioning and on quality of life. A total of 25 patients with chronic hepatitis C infection were investigated. All patients were treated in the Department of Gastroenterology and Hepatology, University of Medicine of Graz, Austria. Psychometric observer rating and self-rating scales were administered 1 month and 3 months after the beginning of the antiviral treatment to evaluate depressive symptoms [Beck Depression Inventory (BDI); Hamilton Depression Scale]. The data on life satisfaction before therapy and health-related quality of life were obtained from the Fragebogen zur Lebenszufriedenheit (FLZ) and the SF-36 (Health Status Questionnaire). Cognitive function was based on the SKT (Syndrom Kurztest). All patients completed the Social Support Questionnaire (SSS), a multidimensional self-report measure of social support. Three months after the initial IFN-alpha administration in the whole sample significant impairments in health-related quality of life were found in the health-related domains "physical functioning", "role physical", "role emotional", "social functioning" and "vitality". The whole sample showed cognitive impairments. No changes in social support were recorded. Three months after the first INF-alpha administration, 48% (n=12) of the sample suffered from moderate clinical depression. In comparison to patients without pathological affective findings, patients with INF-alpha-induced clinical depression showed decreased life satisfaction before the initial antiviral therapy. Impairments in health-related quality of life (SF-36) were found in the sample with clinical depression in the health-related domains "general health", "social functioning", "role emotional", "vitality" and "mental health". Hepatitis C is associated with an increased prevalence of psychiatric disorders, particularly depression. INF-alpha patients having low levels of life satisfaction in the domains "self-concept" (skills, appearance, self-confidence, vitality …), "employment" and "physical health and constitution" seem to face a major risk of depression.

To determine the psychological and social effects of kidney donation on kidney donors by using the short-form 36-item health survey (SF-36) as the quality-of-life questionnaire. A total of 104 living donor nephrectomies have been performed at Kobe University Hospital and Nishinomiya Prefectural Hospital. We mailed the questionnaires to donors or handed them out directly at the outpatient clinic. The first part of the questionnaire consisted of the SF-36 (limitations on physical functioning because of health problems) and the second part consisted of 15 questions about donation-related stress, expenses incurred, physical changes, and pre-existing factors such as relationship to the recipients. The SF-36 and the questionnaire about donor satisfaction were completed by 69 donors (48 women and 21 men; mean age 52.1 +/- 8.2 years), only 6 of whom (9%) reported minor complications with the donor operation. The SF-36 scores of our donors were not significantly different from that of the general U.S. population and U.S. donors. In some categories (physical functioning, role-physical, bodily pain, general health, vitality, and mental health), our donors scored slightly higher than the U.S. general population. Although 97% of the donors would make the same choice again, 3% believed that donating had had a negative impact on their health, and 16% reported negative financial consequences. The quality of life for kidney donors was not affected by donor nephrectomy. Living kidney transplantation seems to be suitable for the rescue of patients with end-stage renal disease. Better psychological and technical preparation for surgery and more consistent follow-up may reduce the negative outcomes even further.

Objective The evidence on the effect of secondhand smoke (SHS) on Health Related Quality of Life (HRQoL) is limited. We examined the relation between SHS and HRQoL among Chinese in Hong Kong. Methods Adult never smokers from a probability sample of three cross-sectional waves (2010, 2012, 2013) of The Hong Kong Family and Health Information Trends Survey who completed the Cantonese-version of Short-Form 12 Health Survey Questionnaire (SF12v2) were included in the data analysis conducted in 2014. Models were used to examine associations of SHS with SF12 domains and summary scores of Physical (PCS12) and Mental Component (MCS12) with subgroups analysis by SHS locations. Results After adjustments, SHS was associated with lower scores on all SF12 domains except physical functioning. PCS12 (regress coefficient=−0.76, 95% CI −1.34 to −0.17) and MCS12 (regress coefficient=−1.35, 95% CI −2.06 to −0.64) were lower in those with SHS exposure than those non-exposed. Those exposed to SHS in outdoor public places had lower scores on most SF12 domains and PSC12 and MCS12. SHS exposure in one's home and workplace was associated with lower scores on role physical, body pain and role emotional while SHS exposure in friends’ homes was additionally associated with lower social functioning and mental health scores. Lower MCS12 was associated with SHS exposure at all locations except one's home. Conclusions Our study showed that SHS exposure, particularly in outdoor public places, was associated with decreased HRQoL. It can provide new evidence for stronger smoke-free policies on public places and promoting smoke-free homes. PMID:26338682

The progressive deterioration of patients with spinocerebellar ataxia (SCA) has a major impact on their health-related quality of life (HRQOL). This study evaluates HRQOL in a sample of patients diagnosed with SCA and aims to estimate the predictive ability of a set of sociodemographic variables for the different dimensions of the General Health Questionnaire. A total of 80 patients diagnosed with SCA were assessed using a sociodemographic questionnaire and the SF-36 General Health Questionnaire. The sociodemographic variables studied were sex, age, presence of a carer, employment status, and time elapsed from diagnosis of the disease. The 8 subscales of the SF-36 show positive and significant correlations to one another. Mean scores obtained on each SF-36 subscale differ between women and men, although this difference is significant only on the general health subscale, with men scoring higher than women. We found significant age differences on the vitality and social function subscales, with higher scores among younger patients (< 34 years). The variable 'presence of a carer' accounts for most of the total variance of the questionnaire. The SF-36 is a valid and useful instrument for evaluating HRQOL in patients diagnosed with SCA. Presence of a carer seems to be a determinant of self-perceived quality of life in these patients. Copyright © 2015 Sociedad Española de Neurología. Publicado por Elsevier España, S.L.U.

We used social attraction methods (decoys and electronic call systems) to attract Caspian terns and snowy plovers to these seven modified islands, and conducted surveys between March and September 2015 to evaluate nest numbers, nest density, and productivity. Results from the 2015 nesting season indicate that island modifications and social attraction measures were successful in establishing Caspian tern breeding colonies at Ponds A16 and SF2 of DENWR. Caspian terns nested on three of the five islands modified for Caspian terns (1 island in Pond A16 and 2 islands in Pond SF2). Caspian terns initiated at least 224 nests, fledged at least 174 chicks, and exhibited a breeding success rate of 0.78 fledged chicks/breeding pair. These results are promising considering it was the first year of the study and there was no prior history of Caspian terns nesting at Ponds A16 and SF2. In contrast, snowy plovers did not attempt to nest on any island in Ponds A16 and SF2. These results demonstrate the potential of social attraction measures to help establish tern nesting colonies in San Francisco Bay. Social attraction measures similar to those used in this study, but targeting other species such as Forster’s terns and American avocets, may help to establish waterbird breeding colonies at wetlands enhanced as part of the SBSP Restoration Project.

We evaluated the validity and responsiveness of three instruments: the numeric rating scale (NRS) pain score, the 8-item Short-Form Health Survey (SF-8), and the 40-item Quality of Recovery from Anesthesia (QoR) Survey in 154 outpatients undergoing anterior cruciate ligament reconstruction (ACLR). The objective was to provide a robust psychometric basis for outcome survey selection for surgical outpatients undergoing regional anesthesia without general anesthesia. Patients undergoing ACLR with a standardized spinal anesthesia plan were randomized to receive a perineural catheter with either placebo injection-infusion, or injection-infusion with levobupivacaine. Patients completed the NRS, SF-8, and QoR instruments for four postoperative days to evaluate pain, physical function, and mental function. Regarding pain, neither the NRS nor the QoR offered advantages over the SF-8. Regarding physical function, the QoR physical independence composite offered no advantage over the SF-8 physical component summary. The QoR physical comfort composite assessed short-term changes in treatment-related side effects, and thus provided information not covered by the SF-8. Regarding mental function, the SF-8 mental component summary and QoR emotional state composite showed little change over the four days, although the latter measure showed higher responsiveness to change. For ACLR outpatients receiving regional anesthesia, the SF-8 is sufficient to assess postoperative pain and physical function. Adding the QoR physical comfort composite will help assess short-term side effects.

The Forgotten Joint Score (FJS) is a newly developed health-related quality of life (HRQoL) questionnaire designed to evaluate the awareness after total knee arthroplasty (TKA). This study cross-culturally adapted and psychometrically validated a simplified Chinese version of the FJS (SC-FJS). Cross-cultural adaptation was performed according to the internationally recognized guidelines. One-hundred and fifty participants who underwent primary TKA were recruited in this study. Cronbach's α and intra-class correlations were used to determine reliability. Construct validity was analyzed by evaluating the correlations between SC-FJS and the Knee Injury and Osteoarthritis Outcome Score (KOOS) and the short form (36) health survey (SF-36). Each of the 12 items was properly responded and correlated with the total items. SC-FJS had excellent reliability [Cronbach's α = 0.907, intra-class correlation coefficient (ICC) = 0.970, 95% CI 0.959-0.978). Elimination of any one item in all did not result in a value of Cronbach's α of <0.80. SC-FJS had a high correlation with symptoms (0.67, p < 0.001) and pain (0.60, p < 0.001) domains of KOOS and social functioning (0.66, p < 0.001) domain of SF-36, and it also moderately correlated with function in daily living (0.53, p < 0.001) and function in sport and recreation (0.40, p < 0.001) domains of KOOS, and physical subscale of SF-36 (0.49-0.53, p < 0.001) but had a low (r = 0.20) or not significant (p > 0.05) correlation with mental subscale of SF-36. SC-FJS demonstrated excellent acceptability, internal consistency, reliability, and construct validity, which can be recommended for patients who underwent joint arthroplasty in Mainland China.

The Oswestry Disability Index v2.0 (ODI), SF36 Physical Function Domain (SF-36 PFD), and PROMIS Physical Function CAT v1.2 (PF CAT) questionnaires were prospectively collected from 1607 patients complaining of back or leg pain, visiting a university-based spine clinic. All questionnaires were collected electronically, using a tablet computer. The aim of this study was to compare the psychometric properties of the PROMIS PF CAT with the ODI and SF36 Physical Function Domain in the same patient population. Evidence-based decision-making is improved by using high-quality patient-reported outcomes measures. Prior studies have revealed the shortcomings of the ODI and SF36, commonly used in spine patients. The PROMIS Network has developed measures with excellent psychometric properties. The Physical Function domain, delivered by Computerized Adaptive Testing (PF CAT), performs well in the spine patient population, though to-date direct comparisons with common measures have not been performed. Standard Rasch analysis was performed to directly compare the psychometrics of the PF CAT, ODI, and SF36 PFD. Spearman correlations were computed to examine the correlations of the three instruments. Time required for administration was also recorded. One thousand six hundred seven patients were administered all assessments. The time required to answer all items in the PF CAT, ODI, and SF-36 PFD was 44, 169, and 99 seconds. The ceiling and floor effects were excellent for the PF CAT (0.81%, 3.86%), while the ceiling effects were marginal and floor effects quite poor for the ODI (6.91% and 44.24%) and SF-36 PFD (5.97% and 23.65%). All instruments significantly correlated with each other. The PROMIS PF CAT outperforms the ODI and SF-36 PFD in the spine patient population and is highly correlated. It has better coverage, while taking less time to administer with fewer questions to answer. 2.

The electron drift velocity, electron energy distribution function (EEDF), density-normalized effective ionization coefficient and density-normalized longitudinal diffusion velocity are calculated in SF6-O2 and SF6-Air mixtures. The experimental results from a pulsed Townsend discharge are plotted for comparison with the numerical results. The reduced field strength varies from 40 Td to 500 Td (1 Townsend=10-17 V·cm2) and the SF6 concentration ranges from 10% to 100%. A Boltzmann equation associated with the two-term spherical harmonic expansion approximation is utilized to gain the swarm parameters in steady-state Townsend. Results show that the accuracy of the Boltzmann solution with a two-term expansion in calculating the electron drift velocity, electron energy distribution function, and density-normalized effective ionization coefficient is acceptable. The effective ionization coefficient presents a distinct relationship with the SF6 content in the mixtures. Moreover, the E/Ncr values in SF6-Air mixtures are higher than those in SF6-O2 mixtures and the calculated value E/Ncr in SF6-O2 and SF6-Air mixtures is lower than the measured value in SF6-N2. Parametric studies conducted on these parameters using the Boltzmann analysis offer substantial insight into the plasma physics, as well as a basis to explore the ozone generation process.

Changes in the SF-8 scores among healthy non-smoking school teachers after the enforcement of a smoke-free school policy: a comparison by passive smoke status

2010-01-01

Background The effects of the enforcement of a smoke-free workplace policy on health-related quality of life (HRQOL) among a healthy population are poorly understood. The present study was undertaken to examine the effects of the enforcement of a smoke-free school policy on HRQOL among healthy non-smoking schoolteachers with respect to their exposure to passive smoke. Methods Two self-reported questionnaire surveys were conducted, the first before and the second after the enforcement of a total smoke-free public school policy in Nara City. A total of 1534 teachers were invited from 62 schools, and their HRQOL was assessed using six domains extracted from the Medical Outcomes Survey Short Form-8 questionnaire (SF-8): general health perception (GH), role functioning-physical (RP), vitality (VT), social functioning (SF), mental health (MH), and role functioning-emotional (RE). The participants were divided into two groups according to their exposure to environmental tobacco smoke (ETS) at baseline: participants not exposed to ETS at school (non-smokers), and participants exposed to ETS at school (passive smokers). Changes in each SF-8 score were evaluated using paired t-tests for each group, and their inter-group differences were evaluated using multiple linear regression analyses adjusted for sex, age, school type, managerial position, and attitude towards a smoke-free policy. Results After ineligible subjects were excluded, 689 teachers were included in the analyses. The number of non-smokers and passive smokers was 447 and 242, respectively. Significant changes in SF-8 scores were observed for MH (0.9; 95% confidence interval [CI], 0.2-1.5) and RE (0.7; 95% CI, 0.0-1.3) in non-smokers, and GH (2.2; 95% CI, 1.2-3.1), VT (1.8; 95% CI, 0.9-2.7), SF (2.7; 95% CI, 1.6-3.8), MH (2.0; 95% CI, 1.0-2.9), and RE (2.0; 95% CI, 1.2-2.8) in passive smokers. In the multiple linear regression analyses, the net changes in the category scores of GH (1.8; 95% CI, 0.7-2.9), VT (1.4, 95% CI, 0.3-2.5), SF (2.5; 95% CI, 1.1-3.9), MH (1.2; 95% CI, 0.1-2.4) and RE (1.6; 95% CI, 0.5-2.7) in passive smokers significantly exceeded those in non-smokers. Conclusions A smoke-free school policy would improve the HRQOL of healthy non-smoking teachers who are exposed to ETS. PMID:20426833

The aim of this study is to confirm the four-dimensional structure and other measurement properties of the Drinking Motives Questionnaire Revised Short Form (DMQ-R SF) among young Hungarian adults in a recreational setting. In a 'Health Tent' at Europe's biggest music and cultural festival, 390 attendees (mean age 23.6, SD = 4.4) completed the DMQ-R SF and answered other alcohol-related questions. Data were analysed by confirmatory factor analysis, repeated measures anova and structural equation modelling. The results confirmed the good measurement properties of the DMQ-R SF in terms of factor loadings, model fit and internal consistency. These statistics were similar for men and women. For both genders, social motives were the most frequently indicated motivational dimension, followed by coping, conformity and enhancement. Social motives were consistently related to drinking, and coping to alcohol-related problems. It seems that the DMQ-R SF is a useful instrument for measuring the motivation to engage in drinking in recreational settings, such as parties, clubs and festivals, where hard-to-reach target groups vulnerable to risky drinking behaviour are present, but time for filling out questionnaires is restricted. © 2010 Australasian Professional Society on Alcohol and other Drugs.

Pelvic joint fusion in patients with severe pelvic girdle pain – a prospective single-subject research design study

PubMed Central

2014-01-01

Background The fusion of the pelvic joints in patients with severe pelvic girdle pain (PGP) is a controversial and insufficiently studied procedure. The aims of this study were to evaluate physical function and pain after sacroiliac joint (SIJ) fusion. Methods A single-subject research design study with repeated measurements was conducted; pre-operatively and at 3, 6 and 12 months post-operatively. The outcome measures considered were the Oswestry disability index (ODI), visual analogue scale (VAS), and SF-36. Eight patients with severe PGP received open-accessed unilateral anterior SIJ fusion and fusion of the pubic symphysis. Results Seven patients reported positive results from the surgery. At 1 year post-operation, significant (p < 0.001) reductions in ODI (54 to 37) and VAS (82 to 57) were reported. The physical functioning, bodily pain, and social functioning scores in the SF-36 were also improved. Conclusion Positive and significant changes in disability and pain at 1 year after SIJ fusion were observed. Despite these positive results, open accessed anterior fusion of the SIJ was associated with adverse events and complications such as infection and nerve damage. PMID:24629145

Measures of health related quality of life (HRQoL) in patients with α1-antitrypsin deficiency (AATD) can help to determine the impact of the disease and provide an important insight into the intervention outcomes. There is few data regarding this issue in the literature. The aim of this study is to assess the relationship between HRQoL and gender, functional parameters and history of hospitalizations in patients with AATD. This is a cross-sectional study of 26 patients with severe AATD recruited in the pulmonology outpatient clinic at a tertiary care medical center. Social-demographic, clinical and functional parameters were recorded and HRQoL was assessed with the Portuguese version of the medical outcome study short form-36 (SF-36) self-administered questionnaire. Older patients, females and patients with at least one hospitalization in the previous year due to respiratory disease had statistical lower scores in some dimensions of the SF-36 questionnaire. Superior FEV1 and higher distance mark in the 6-min walking test distance influenced positively several dimensions of the questionnaire. Higher scores in the mMRC scale influenced negatively the HRQoL. These data suggests that older and female patients with AATD have worse HRQoL. Hospitalizations and functional markers of respiratory disease progression influenced negatively the HRQoL, suggesting that the SF-36 questionnaire could be useful as an outcome for AATD patients with lung involvement.

To evaluate the quality of life among doctors, nurses, and occupational safety and health technologists (OSHT). Cross-sectional study was undertaken in a population of healthcare workers in 10 Italian regions. The Italian version of short form-36 (SF-36) was anonymously and voluntarily self-administered by participants to assess the perceived health-related quality of life (HRQOL). The HRQOL scores for the sample and the Italian population were compared. A multiple linear regression was performed to assess the influence of age, gender, role, socializing time, working time, years spent in healthcare and years spent in the specific department on the SF-36 score. The sample included 324 healthcare workers [57.1% women, mean age 39.0 (standard deviation 10.2) years]: 52.6% were medical doctors, 36.8% were nurses and 10.5% were OSHTs. Workers with a career of >15 years achieved a general health score lower than that of workers with a shorter career, while those who spent more time in socializing activities achieved a higher mental health score. The multivariate analysis showed that increasing age is positively related to role emotional levels (β = 0.243; P = 0.002), while it appears to be inversely related to general health (β = -0.218; P = 0.007) and physical function (β = -0.246; P = 0.001). Nurses had lower scores for bodily pain (β = -0.214; P < 0.001), social function (β = -0.242; P = 0.001) and role emotional (β = -0.211; P = 0.006) compared with doctors. Compared with the general Italian population, healthcare workers had higher scores for general health, physical function, role physical, bodily pain and mental health, and lower scores for vitality, social function and role emotional. Healthcare workers have different levels of HRQOL related to their professional role. In particular, nurses have lower quality of life. These results may help to identify the main roles and attitudes that could cause frustration, dissatisfaction and emotional stress in healthcare workers.

Ellert, U; Lampert, T; Ravens-Sieberer, U

2005-12-01

The SF-8, a relatively new instrument for measuring health-related quality of life, was used in the German National Telephone Health Survey 2003. The SF-8 provides results which are comparable to those of the SF-36, the instrument most commonly used internationally. The German National Telephone Health Survey provides nationally representative data for the residential population in Germany aged 18 and older. In addition to the measurement of health-related quality of life, comprehensive information on chronic illnesses and complaints, health care needs, utilisation of health care, risk factors, risk behaviour and social status is also collected, making differentiated analyses possible. According to the data collected, men rate their quality of life in all dimensions higher than women. With increasing age, quality of life for both men and women decreases in the physical dimensions, while increasing in the mental health dimensions. Apart from chronic disease and pain having a negative impact on health-related quality of life, social differences are also observable, in that worse health-related quality of life is reported by respondents with lower socioeconomic status.

2017-04-01

The Social Problem Solving Inventory-Revised Short-Form (SPSI-R:SF) has been used in several countries to identify problem-solving deficits among clinical and general populations in order to guide cognitive-behavioural interventions. Yet, very few studies have evaluated its psychometric properties. Three language versions of the questionnaire were administered to a general population sample comprising 1000 participants (771 English-, 178 Afrikaans- and 101 Xhosa-speakers). Of these participants, 210 were randomly selected to establish test-retest reliability (70 in each language). Principal component analysis was performed to examine the applicability of the factor structure of the original questionnaire to the South African data. Supplementary psychometric analyses were performed, including internal consistency and test-retest reliability. Collectively, results provide initial evidence of the reliability and validity of the SPSI-R:SF for the assessment of problem solving deficits in South Africa. Further studies that explore how the Afrikaans language version of the SPSI-R:SF can be improved and that establish the predictive validity of scores on the SPSI-R:SF are needed. © 2015 International Union of Psychological Science.

This study sought to evaluate the association between the impact of oral disorders in terms of physical/psychosocial dimensions and quality of life among the elderly. It involved a cross-sectional study conducted among the elderly (65-74 years) in 2008/2009. The social impact was assessed using the Oral Health Impact Profile (OHIP 14) and the quality of life using the SF 12 Short-Form Health Survey. Descriptive, univariate and multivariate (logistic regression) analysis was conducted with correction for the design effect, using SPSS(r)18.0 software. Of the 800 individuals approached, 736 elderly individuals participated (TR = 92%), with a mean age of 67.77 years, the majority of whom showed no impact based on the measurement of the prevalence of OHIP. The functional limitation dimension of the OHIP was associated with the physical domain of the SF12, irrespective of the other variables investigated. However, the seriousness of OHIP and its psychological discomfort and disability dimensions was associated with the mental domain of the SF12. The conclusion reached is that some impacts of oral disorders were associated with unsatisfactory quality of life in the physical and mental domains.

Telephone vs. mail survey gives different SF-36 quality-of-life scores among cancer survivors.

Buskirk, Trent D; Stein, Kevin D

2008-10-01

To assess whether SF-36 quality-of-life (QOL) subscale scores varied across two survey modes controlling for cancer type and diagnosis cohort. Stratified random samples of 720 cancer survivors from six cancer types and three time-since diagnosis cohorts were selected from two state cancer registries. Selected survivors were randomly assigned to mail, telephone, or choice of these for survey administration. This study analyzes completed questionnaires obtained from 140 and 155 survivors who were assigned to telephone and mail, respectively. A significant multivariate effect for survey mode was noted. Mean levels for each subscale controlling for age and accounting for cancer type were higher for telephone compared to mail respondents; significant differences were noted for vitality, role physical, and mental health. The impact of cancer type on QOL subscales was not significant, and the effect of mode was consistent across cancer type. Previous findings in mode effects for the SF-36 are reproduced here among cancer survivors who may feel more comfortable revealing physical and emotional deficits via mail rather than by telephone. For cancer survivors, it may be that "social desirability" favors responses implying more functioning be it perceived, mental, or physical.

This single-blind, randomized controlled trial evaluated the impact of the Transcendental Meditation program plus standard care as compared with standard care alone on the quality of life (QOL) of older women (>or=55 years) with stage II to IV breast cancer. One hundred and thirty women (mean age = 63.8) were randomly assigned to either experimental (n = 64) or control (n = 66) groups. Functional Assessment of Cancer Therapy-Breast (FACT-B), Functional Assessment of Chronic Illness Therapy- Spiritual Well-Being (FACIT-SP), and Short-Form (SF)-36 mental health and vitality scales were administered every 6 months over an average 18-month intervention period. Significant improvements were found in the Transcendental Meditation group compared with controls in overall QOL, measured by the FACT-B total score (P = .037), emotional well-being (P = .046), and social well-being (P = .003) subscales, and SF-36 mental health ( P = .017). It is recommended that this stress reduction program, with its ease of implementation and home practice, be adopted in public health programs.

Functional domains of the human splicing factor ASF/SF2.

Zuo, P; Manley, J L

1993-01-01

The human splicing factor ASF/SF2 displays two predominant activities in in vitro splicing assays: (i) it is an essential factor apparently required for all splices and (ii) it is able to switch utilization of alternative 5' splice sites in a concentration-dependent manner. ASF/SF2 is the prototype of a family of proteins typified by the presence of one or two RNP-type RNA binding domains (RBDs) and a region highly enriched in repeating arginine-serine dipeptides (RS regions). Here we describe a functional analysis of ASF/SF2, which defines several regions essential for one, or both, of its two principal activities, and provides insights into how this type of protein functions in splicing. Two isoforms of the protein, which arise from alternative splicing, are by themselves inactive, but each can block the activity of ASF/SF2, thereby functioning as splicing repressors. Some, but not all, mutations in the RS region prevent ASF/SF2 from functioning as an essential splicing factor. However, the entire RS region can be deleted without reducing splice site switching activity, indicating that it is not absolutely required for interaction with other splicing factors. Experiments with deletion and substitution mutants reveal that the protein contains two related, but highly diverged, RBDs, and that both are essential for activity. Each RBD by itself retains the ability to bind RNA, although optimal binding requires both domains. Images PMID:8223481

Lower physical and social functioning in pregnancy has been linked to an increased risk of preterm delivery and low birth weight infants, butt few studies have examined racial differences in pregnant women's perception of their functioning. Even fewer studies have elucidated the demographic and clinical factors contributing to racial differences in functioning. Our objective was to determine whether there are racial differences in health-related quality of life (HRQoL) in early pregnancy; and if so, to identify the contributions of socio-demographic characteristics, depression symptoms, social support and clinical factors to these differences. Cross-sectional study of 175 women in early pregnancy attending prenatal clinics in urban setting. In multivariate analysis, we assessed the independent relation of black race (compared to white) to HRQoL scores from the eight domains of the Medical Outcomes (SF-36) SURVEY: Physical Functioning, Role-Physical, Bodily Pain, Vitality, General Health, Social Functioning, Role-Emotional, and Mental Health. We compared socio-demographic and clinical factors and depression symptoms between black and white women and assessed the relative importance of these factors in explaining racial differences in physical and social functioning. Black women comprised 59% of the sample; white women comprised 41%. Before adjustment, black women had scores that were 14 points lower in Physical Function and Bodily Pain, 8 points lower in General Health, 4 points lower in Vitality and 7 points lower in Social Functioning. After adjustment for depression symptoms, social support and clinical factors, black women still had HRQoL scores that were 4 to 10 points lower than white women, but the differences were no longer statistically significant. Level of social support and payment source accounted for most of the variation in Physical Functioning, Bodily Pain and General Health. Social support accounted for most of the differences in Vitality and Social Functioning. Payment source and social support accounted for much of the racial differences in physical and social function scores. Efforts to reduce racial differences might focus on improving social support networks and Socio-economic barriers.

The purpose of this study was to examine the characteristics of elderly subjects who had objectionable levels of volatile sulfur compound (VSC). In 2002, a total of 115 85-year-old persons in Japan were subjected to oral examinations, tongue coat collections, measurements of VSCs levels inside the mouth using a portable gas chromatography (Oral Chroma, Abilit, Japan), and assessments of quality of life (QOL) using an SF-36 questionnaire. Sixty-six of the subjects were edentulous and 49 were dentulous. They were divided into two groups by VSC levels, those with oral malodor (both H2S > 112 ppb and CH3SH > 26 ppb; subjects with oral malodor, OM group; n = 7) and those without (n = 108). Our results showed that tongue coat deposit amounts and proportion of dentulous subjects were significantly higher in the OM group. Further, in an analysis of QOL, the SF-36 scores for vitality, social functioning and mental health were significantly higher in OM. We found that elderly subjects with oral malodor tended to be dentulous and had large deposits of tongue coating. However, oral malodor in the OM group subjects did not appear to cause a disadvantage in their social lives.

Developing the environment-friendly insulation gases to replace sulfur hexafluoride (SF 6 ) has attracted considerable experimental and theoretical attentions but without success. A computational methodology was presented herein for prediction on dielectric strength and boiling point of arbitrary gaseous molecules in the purpose of molecular design and screening. New structure-activity relationship (SAR) models have been established by combining the density-dependent properties of the electrostatic potential surface, including surface area and the statistical variance of the surface potentials, with the molecular properties including polarizability, electronegativity, and hardness. All the descriptors in the SAR models were calculated using density functional theory. The substitution effect of SF 6 by various functional groups was studied systematically. It was found that CF 3 is the most effective functional group to improve the dielectric strength due to the large surface area and polarizability. However, all the substitutes exhibit higher boiling points than SF 6 because the molecular hardness decreases. The balance between E r and T b could be achieved by minimizing the local polarity of the molecules. SF 5 CN and SF 5 CFO were found to be the potent candidates to replace SF 6 in view of their large dielectric strengths and low boiling points. © 2017 Wiley Periodicals, Inc. © 2017 Wiley Periodicals, Inc.

This study aims to evaluate the quality of life (QOL) of patients who underwent resection of oral cancer and reconstruction by free anierolateral thigh perforator flaps (ALTF). A total of 32 patients with oral and maxillofacial malignancies who had undergone the resection of oral cancer and reconstruction by ALTF were retrospectively analyzed. At 12 months postoperatively, the QOL of these patients was assessed by using the 14-item oral health impact profile (OHIP-14) and the medical outcome study short form-36 (SF-36) questionnaires. A total of 32 questionnaires were collected. In SF-36, the highest scoring domains were bodily pain (78.58 ± 14.82), physical functioning (72.08 ± 27.86), and the role of physical (60.00 ± 42.63), whereas the lowest scoring domains were role-emotional (41.67 ± 39.62), followed by mental health (50.75 ± 13.07) and health transition (54.17 ± 21.75). In OHIP-14, the lowest scoring domains were social disability (34.50 ± 11.32) and handicap (36.04 ± 12.05), indicating the functional recovery was better; and the highest scoring domains were physical pain (73.50 ± 18.96) and psychological discomfort (60.17 ± 20.66), indicating the functional recovery was worse. The ALTF is an ideal selection for the reconstruction of oral defects after cancer resection. In using this flap, the basic social need of patients after surgery can be satisfied. Moreover, the appearance and the functions of chewing, deglutition, and speech can be restored in varying degrees. Thus, ALTF can improve the patients' QOL.

To compare a specialized interprofessional team approach to community-based stroke rehabilitation with usual home care for stroke survivors using home care services. Randomized controlled trial of 101 community-living stroke survivors (<18 months post-stroke) using home care services. Subjects were randomized to intervention (n=52) or control (n=49) groups. The intervention was a 12-month specialized, evidence-based rehabilitation strategy involving an interprofessional team. The primary outcome was change in health-related quality of life and functioning (SF-36) from baseline to 12 months. Secondary outcomes were number of strokes during the 12-month follow-up, and changes in community reintegration (RNLI), perceived social support (PRQ85-Part 2), anxiety and depressive symptoms (Kessler-10), cognitive function (SPMSQ), and costs of use of health services from baseline to 12 months. A total of 82 subjects completed the 12-month follow-up. Compared with the usual care group, stroke survivors in the intervention group showed clinically important (although not statistically significant) greater improvements from baseline in mean SF-36 physical functioning score (5.87, 95% CI -3.98 to 15.7; p=0.24) and social functioning score (9.03, CI-7.50 to 25.6; p=0.28). The groups did not differ for any of the secondary effectiveness outcomes. There was a higher total per-person costs of use of health services in the intervention group compared to usual home care although the difference was not statistically significant (p=0.76). A 12-month specialized, interprofessional team is a feasible and acceptable approach to community-based stroke rehabilitation that produced greater improvements in quality of life compared to usual home care.

A Systems Biology Approach to Synovial Joint Lubrication in Health, Injury, and Disease

PubMed Central

Hui, Alexander Y.; McCarty, William J.; Masuda, Koichi; Firestein, Gary S.; Sah, Robert L.

2013-01-01

The synovial joint contains synovial fluid (SF) within a cavity bounded by articular cartilage and synovium. SF is a viscous fluid that has lubrication, metabolic, and regulatory functions within synovial joints. SF contains lubricant molecules, including proteoglycan-4 and hyaluronan. SF is an ultrafiltrate of plasma with secreted contributions from cell populations lining and within the synovial joint space, including chondrocytes and synoviocytes. Maintenance of normal SF lubricant composition and function are important for joint homeostasis. In osteoarthritis, rheumatoid arthritis, and joint injury, changes in lubricant composition and function accompany alterations in the cytokine and growth factor environment and increased fluid and molecular transport through joint tissues. Thus, understanding the synovial joint lubrication system requires a multi-faceted study of the various parts of the synovial joint and their interactions. Systems biology approaches at multiple scales are being used to describe the molecular, cellular, and tissue components and their interactions that comprise the functioning synovial joint. Analyses of the transcriptome and proteome of SF, cartilage, and synovium suggest that particular molecules and pathways play important roles in joint homeostasis and disease. Such information may be integrated with physicochemical tissue descriptions to construct integrative models of the synovial joint that ultimately may explain maintenance of health, recovery from injury, or development and progression of arthritis.

Internationally there is a growing interest in the mental wellbeing of young people. However, it is unclear whether mental wellbeing is best conceptualized as a general wellbeing factor or a multidimensional construct. This paper investigated whether mental wellbeing, measured by the Mental Health Continuum-Short Form (MHC-SF), is best represented by: (1) a single-factor general model; (2) a three-factor multidimensional model or (3) a combination of both (bifactor model). 2220 young Australians aged between 16 and 25 years completed an online survey including the MHC-SF and a range of other wellbeing and mental ill-health measures. Exploratory factor analysis supported a bifactor solution, comprised of a general wellbeing factor, and specific group factors of psychological, social and emotional wellbeing. Confirmatory factor analysis indicated that the bifactor model had a better fit than competing single and three-factor models. The MHC-SF total score was more strongly associated with other wellbeing and mental ill-health measures than the social, emotional or psychological subscale scores. Findings indicate that the mental wellbeing of young people is best conceptualized as an overarching latent construct (general wellbeing) to which emotional, social and psychological domains contribute. The MHC-SF total score is a valid and reliable measure of this general wellbeing factor. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

This study examined the association between emotional intelligence (EI), anxiety, depression, and mental, social, and physical health in university students. The sample was made up of 184 university students (38 men and 146 women). El was evaluated by the Trait Meta-Mood Scale (Salovey, Mayer, Goldman, Turvey, and Palfai, 1995), which evaluates the three dimensions (Attention, Clarity, and Mood Repair). Anxiety was evaluated with the Trait Anxiety Questionnaire (Spielberger, Gorsuch, Lushene, Vagg, and Jacobs, 1983) and depression with the Beck Depression Inventory (Beck, Rush, Shaw, and Emery, 1979). Mental, social, and physical health were evaluated with the SF-12 Health Survey (Ware, Kosinski, and Keller, 1996). Results showed that high Emotional Attention was positively and significantly related to high anxiety, depression, and to low levels of Role Emotional, Social Functioning, and Mental Health. However, high levels of emotional Clarity and Mood Repair were related to low levels of anxiety and depression, high Role Physical, Social Functioning, Mental Health, Vitality, and General Health. This study confirmed the predictive value of Attention, Clarity and Mood Repair regarding the levels of anxiety, depression, and areas related to mental, social, and physical health in university students.

Obesity is a stigmatizing condition associated with adverse psychosocial consequences. The relative importance of weight stigma in reducing health utility or the value a person places on their current health state is unknown. We conducted a telephone survey of patients with obesity. All were seeking weight loss surgery at two bariatric centers (70 % response rate). We assessed patients' health utility (preference-based quality life measure) via a series of standard gamble scenarios assessing patients' willingness to risk death to lose various amounts of weight or achieve perfect health (range 0 to 1; 0 = death and 1 = most valued health/weight state). Multivariable models assessed associations among quality of life domains from the Short-form 36 (SF-36) and Impact of Weight on Quality of Life-lite (IWQOL-lite) and patients' health utility. Our study sample (n = 574) had a mean body mass index of 46.5 kg/m(2) and a mean health utility of 0.87, reflecting the group's average willingness to accept a 13 % risk of death to achieve their most desired health/weight state; utilities were highly variable, however, with 10 % reporting a utility of 1.00 and 27 % reporting a utility lower than 0.90. Among the IWQOL-lite subscales, Public Distress and Work Life were the only two subscales significantly associated with patients' utility after adjustment for sociodemographic factors. Among the SF-36 subscales, Role Physical, Physical Functioning, and Role Emotional were significantly associated with patients' utility. When the leading subscales on both IWQOL-lite and SF-36 were considered together, Role Physical, Public Distress, and to a lesser degree Role Emotional remained independently associated with patients' health utility. Patients seeking weight loss surgery report health utilities similar to those reported for people living with diabetes or with laryngeal cancer; however, utility values varied widely with more than a quarter of patients willing to accept more than a 10 % risk of death to achieve their most valued health/weight state. Interference with role functioning due to physical limitations and obesity-related social stigma were strong determinants of reduced health utility.

To evaluate health related quality of life (HRQOL) in TEACH, a phase III randomized placebo controlled trial of 12 months of adjuvant lapatinib in HER2 positive (HER2+) early breast cancer which demonstrated marginal benefit in disease-free survival. Women on TEACH completed the Short Form 36-item health survey (version2; SF-36v2) at the baseline, six and 12 months after therapy initiation and six monthly thereafter. Mean changes were compared between treatment groups for two summary measures (Physical and Mental Component Summary scores; PCS and MCS) and eight domain measures (physical functioning, role physical, bodily pain, general health, vitality, social functioning, role emotional and mental health), and in patients discontinuing therapy. A five-point change was deemed a Minimally Clinically Important Difference (MCID). Response analysis compared the proportion of patients demonstrating a MCID in HRQOL, and a regression analysis identified predictors of worsening HRQOL. 3074 (97%) subjects completed baseline SF-36v2. During the initial 12 months, summary SF-36v2 scores decreased in both arms but did not reach Minimally Clinically Important Difference (MCID) despite significant incidences of diarrhoea and rash in lapatinib treated patients. At six months, women receiving lapatinib had more significant reductions (p < 0.01 versus placebo) in social functioning. Early treatment discontinuations were more frequent on lapatinib (32% versus 18%), and were associated with more substantial decrements of HRQOL in both arms. For those discontinuing primarily due to adverse events, decrements in HRQOL reached MCID in Mental Summary scores (MCS) only. Lower baseline HRQOL was a significant predictor of worsening HRQOL (p < 0.05). Despite frequent but usually mild toxicities, adjuvant lapatinib is not associated with clinically significant decreases in overall HRQOL. These placebo-controlled results may also help to inform physicians and patients using lapatinib in metastatic HER2 positive breast cancer. GlaxoSmithKline.

Why and when social support predicts older adults' pain-related disability: a longitudinal study.

PubMed

Matos, Marta; Bernardes, Sónia F; Goubert, Liesbet

2017-10-01

Pain-related social support has been shown to be directly associated with pain-related disability, depending on whether it promotes functional autonomy or dependence. However, previous studies mostly relied on cross-sectional methods, precluding conclusions on the temporal relationship between pain-related social support and disability. Also, research on the behavioral and psychological processes that account for such a relationship is scarce. Therefore, this study aimed at investigating the following longitudinally: (1) direct effects of social support for functional autonomy/dependence on pain-related disability, (2) mediating role of physical functioning, pain-related self-efficacy, and fear, and (3) whether pain duration and pain intensity moderate such mediating processes. A total of 168 older adults (Mage = 78.3; SDage = 8.7) participated in a 3-month prospective design, with 3 moments of measurement, with a 6-week lag between them. Participants completed the Formal Social Support for Autonomy and Dependence in Pain Inventory, the Brief Pain Inventory, the 36-SF Health Survey, behavioral tasks from the Senior Fitness Test, the Pain Self-Efficacy Questionnaire, and the Tampa Scale for Kinesiophobia. Moderated mediation analyses showed that formal social support for functional dependence (T1) predicted an increase in pain-related disability (T3), that was mediated by self-reported physical functioning (T2) and by pain-related self-efficacy (T2) at short to moderate pain duration and at low to moderate pain intensity, but not at higher levels. Findings emphasized that social support for functional dependence is a risk factor for pain-related disability and uncovered the "why" and "when" of this relationship. Implications for the design of social support interventions aiming at promoting older adults' healthy aging despite chronic pain are drawn.

Physical, cognitive and psychosocial functioning are frequently impaired in dialysis patients and impairment in these domains relates to poor outcome. The aim of this analysis was to compare the prevalence of impairment as measured by the Kidney Disease Quality of Life- Short Form (KDQOL-SF) subscales between the different age categories and to assess whether the association of these subscales with mortality differs between younger and older dialysis patients. This study included data from 714 prevalent hemodialysis patients, from 26 centres, who were enrolled in the CONvective TRAnsport STudy (CONTRAST NCT00205556, 09-12-2005). Baseline HRQOL domains were evaluated for patients <65 years, 65-74 years and over 75 years. Multivariable Cox proportional hazards analyses were performed to assess the relation between the separate domains and 2-year mortality. Emotional health was higher in patients over the age of 75 compared to younger patients (mean level 71, 73 and 77 for increasing age categories respectively, p = 0.02), whilst physical functioning was significantly lower in older patients (mean level 60, 48 and 40, p < 0.01). A low level of physical functioning (Hazard Ratio (HR) 1.72 [95%Confidence Interval (CI) 1.02-2.73]), emotional health (HR 1.85 [95% 1.30-2.63]), and social functioning (HR 1.59 [95% CI 1.12-2.26]), was individually associated with an increased 2-year mortality within the whole population. The absence of effect modification suggests no evidence for different relations within the older age groups. In dialysis patients, older age is associated with lower levels of physical functioning, whilst the level of emotional health is not associated with age. KDQOL-SF domains physical functioning, emotional health and social functioning are independently associated with mortality in prevalent younger and older hemodialysis patients.

There is controversy and ongoing interest on the measurement of functionality in the personal and social level. (1) to validate the Greek version of the World Health Organization Disability Assessment Schedule (WHO DAS II) and (2) to determine its added value to the physical and psychological health subscales of the Short Form 36 (SF-36). In a cross-sectional design, data were collected between December 2014 and March 2015 by using three questionnaires (WHO DAS II, SF-36, PSS-14) in a sample of people with disabilities (n = 101) and without disabilities (n = 109) in Athens, Greece. WHO DAS II internal consistency, construct and criterion-related validity were assessed by Cronbach alpha, exploratory factor analysis and correlations; its added value by multivariable linear regression. Cronbach Alpha's were satisfactory for the WHO DAS II, PSS-14 and SF-36 (0.85, 0.88 and 0.96 respectively). Exploratory factor analysis confirmed the existence of one or two factors in people with or without disabilities, respectively. WHO DAS II score showed significant negative correlation with the physical and mental health scale of SF-36 score, especially strong for physical health while was positively related to PSS-14 score. In multivariate analysis mental health appraisal was related to perceived stress in both groups. This study support the validity of the Greek version of WHO DAS II and warranted its use in assessment and follow up of people with disabilities, contributing to the development of suitable policies to cover their needs and providing comparable data with other surveys using the same instrument.

Genome-wide association studies have identified a locus on chromosome 19 associated with plasma triglyceride (TG) concentration and nonalcoholic fatty liver disease. However, the identity and functional role of the gene(s) responsible for these associations remain unknown. Of 19 expressed genes contained in this locus, none has previously been implicated in lipid metabolism. We performed gene expression studies and expression quantitative trait locus analysis in 206 human liver samples to identify the putative causal gene. Transmembrane 6 superfamily member 2 (TM6SF2), a gene with hitherto unknown function, expressed predominantly in liver and intestine, was identified as the putative causal gene. TM6SF2 encodes a protein of 351 amino acids with 7–10 predicted transmembrane domains. Otherwise, no other protein features were identified which could help to elucidate the function of TM6SF2. Protein subcellular localization studies with confocal microscopy demonstrated that TM6SF2 is localized in the endoplasmic reticulum and the ER-Golgi intermediate compartment of human liver cells. Functional studies for secretion of TG-rich lipoproteins (TRLs) and lipid droplet content were performed in human hepatoma Huh7 and HepG2 cells using confocal microscopy and siRNA inhibition and overexpression techniques. In agreement with the genome-wide association data, it was found that TM6SF2 siRNA inhibition was associated with reduced secretion of TRLs and increased cellular TG concentration and lipid droplet content, whereas TM6SF2 overexpression reduced liver cell steatosis. We conclude that TM6SF2 is a regulator of liver fat metabolism with opposing effects on the secretion of TRLs and hepatic lipid droplet content. PMID:24927523

Expression of TM4SF10, a Claudin/EMP/PMP22 family cell junction protein, during mouse kidney development and podocyte differentiation.

Cell junctions in the nephron are highly specialized to perform specific and distinct filtration and reabsorption functions. The mature kidney forms complex cell junctions including slit diaphragms that prevent the passage of serum proteins into the filtrate, and tubule cell junctions that regulate specific paracellular ion reuptake. We have investigated the expression of TM4SF10 (Trans-Membrane tetra(4)-Span Family 10) in mouse kidneys. TM4SF10 is the vertebrate orthologue of Caenorhabditis elegans VAB-9, a tetraspan adherens junction protein in the PMP22/EMP/Claudin family of proteins. We found that TM4SF10 localizes at the basal-most region of podocyte precursors before the capillary loop stage, at some tubule precursors, and at the ureteric bud junction with S-shaped bodies. Overall expression of TM4SF10 peaked at postnatal day 4 and was virtually absent in adult kidneys. The very limited expression of TM4SF10 protein that persisted into adulthood was restricted to a few tubule segments but remained localized to the basal region of lateral membranes. In undifferentiated cultured podocytes, TM4SF10 localized to the perinuclear region and translocated to the cell membrane after Cadherin appearance at cell-cell contacts. TM4SF10 colocalized with ZO1 and p120ctn in undifferentiated confluent podocytes and also colocalized with the tips of actin filaments at cell contacts. Upon differentiation of cultured podocytes, TM4SF10 protein disappeared from cell contacts and expression ceased. These results suggest that TM4SF10 functions during differentiation of podocytes and may participate in the maturation of cell junctions from simple adherens junctions to elaborate slit diaphragms. TM4SF10 may define a new class of Claudin-like proteins that function during junctional development.

Noncoding Subgenomic Flavivirus RNA Is Processed by the Mosquito RNA Interference Machinery and Determines West Nile Virus Transmission by Culex pipiens Mosquitoes.

Flaviviruses, such as Zika virus, yellow fever virus, dengue virus, and West Nile virus (WNV), are a serious concern for human health. Flaviviruses produce an abundant noncoding subgenomic flavivirus RNA (sfRNA) in infected cells. sfRNA results from stalling of the host 5'-3' exoribonuclease XRN1/Pacman on conserved RNA structures in the 3' untranslated region (UTR) of the viral genomic RNA. sfRNA production is conserved in insect-specific, mosquito-borne, and tick-borne flaviviruses and flaviviruses with no known vector, suggesting a pivotal role for sfRNA in the flavivirus life cycle. Here, we investigated the function of sfRNA during WNV infection of Culex pipiens mosquitoes and evaluated its role in determining vector competence. An sfRNA1-deficient WNV was generated that displayed growth kinetics similar to those of wild-type WNV in both RNA interference (RNAi)-competent and -compromised mosquito cell lines. Small-RNA deep sequencing of WNV-infected mosquitoes indicated an active small interfering RNA (siRNA)-based antiviral response for both the wild-type and sfRNA1-deficient viruses. Additionally, we provide the first evidence that sfRNA is an RNAi substrate in vivo Two reproducible small-RNA hot spots within the 3' UTR/sfRNA of the wild-type virus mapped to RNA stem-loops SL-III and 3' SL, which stick out of the three-dimensional (3D) sfRNA structure model. Importantly, we demonstrate that sfRNA-deficient WNV displays significantly decreased infection and transmission rates in vivo when administered via the blood meal. Finally, we show that transmission and infection rates are not affected by sfRNA after intrathoracic injection, thereby identifying sfRNA as a key driver to overcome the mosquito midgut infection barrier. This is the first report to describe a key biological function of sfRNA for flavivirus infection of the arthropod vector, providing an explanation for the strict conservation of sfRNA production. Understanding the flavivirus transmission cycle is important to identify novel targets to interfere with disease and to aid development of virus control strategies. Flaviviruses produce an abundant noncoding viral RNA called sfRNA in both arthropod and mammalian cells. To evaluate the role of sfRNA in flavivirus transmission, we infected mosquitoes with the flavivirus West Nile virus and an sfRNA-deficient mutant West Nile virus. We demonstrate that sfRNA determines the infection and transmission rates of West Nile virus in Culex pipiens mosquitoes. Comparison of infection via the blood meal versus intrathoracic injection, which bypasses the midgut, revealed that sfRNA is important to overcome the mosquito midgut barrier. We also show that sfRNA is processed by the antiviral RNA interference machinery in mosquitoes. This is the first report to describe a pivotal biological function of sfRNA in arthropods. The results explain why sfRNA production is evolutionarily conserved. Copyright © 2016, American Society for Microbiology. All Rights Reserved.

Objective Assess quality of life in patients with systemic lupus erythematosus (SLE) presenting with neuropsychiatric symptoms (neuropsychiatric SLE, NPSLE). Methods Quality of life was assessed using the Short-Form 36 item Health Survey (SF-36) in patients visiting the Leiden NPSLE clinic at baseline and at follow-up. SF-36 subscales and summary scores were calculated and compared with quality of life of the general Dutch population and patients with other chronic diseases. Results At baseline, quality of life was assessed in 248 SLE patients, of whom 98 had NPSLE (39.7%). Follow-up data were available for 104 patients (42%), of whom 64 had NPSLE (61.5%). SLE patients presenting neuropsychiatric symptoms showed a significantly reduced quality of life in all subscales of the SF-36. Quality of life at follow-up showed a significant improvement in physical functioning role ( p = 0.001), social functioning ( p = 0.007), vitality ( p = 0.023), mental health ( p = 0.014) and mental component score ( p = 0.042) in patients with neuropsychiatric symptoms not attributed to SLE, but no significant improvement was seen in patients with NPSLE. Conclusion Quality of life is significantly reduced in patients with SLE presenting neuropsychiatric symptoms compared with the general population and patients with other chronic diseases. Quality of life remains considerably impaired at follow-up. Our results illustrate the need for biopsychosocial care in patients with SLE and neuropsychiatric symptoms.

The purpose of this study was to elucidate determinants of quality of life (QOL) in anorexia nervosa (AN) patients. Twenty-one female patients with AN participated in the study. QOL was assessed with the 36-Item Short Form Health Survey (SF-36), and cognitive function was evaluated using the Wisconsin Card Sorting Test Keio version, the Rey Complex Figure Test, and the Social Cognition Screening Questionnaire. Clinical symptoms were evaluated with the Beck Depression Inventory-II, the State-Trait Anxiety Inventory-Form JYZ (STAI-JYZ), and the Maudsley Obsessive Compulsive Inventory. The Difficulty Maintaining Set score of the Wisconsin Card Sorting Test Keio version was negatively correlated to the SF-36 Physical Component Summary. Scores of the Beck Depression Inventory-II and the STAI-JYZ State and Trait were negatively correlated to the SF-36 Mental Component Summary (MCS), and the Central Coherence Index 30-min Delayed Recall score of the Rey Complex Figure Test was positively correlated with the MCS. Stepwise regression analysis showed that the Difficulty Maintaining Set score was an independent predictor of the Physical Component Summary and scores for Central Coherence Index 30-min Delayed Recall and the STAI-JYZ Trait-predicted MCS. These results suggest that not only trait anxiety but also poor central coherence and impaired ability to maintain new rule worsen AN patients' QOL. © 2016 The Authors.

Using representative survey data of Filipino Americans in Honolulu and San Francisco (SF) (N = 2,259), we examined the roles of emotional support and instrumental support on gambling participation. With considerable difference in gambling environments between two regions, we conducted two sets of hierarchical regression analyses for Honolulu sample, which has restricted gambling laws, and SF sample, which has legal gambling environment, and compared the effects of two types of social support on gambling participation. The results indicated that emotional support was positively and instrumental support was negatively associated with gambling participation among Filipino Americans in Honolulu. However, neither type of social support was significantly associated with gambling participation among Filipino Americans living in SF. This study highlights the differing roles and effects of instrumental and emotional support on gambling where gambling is restricted. It also suggests that gambling behaviors of Filipino Americans are subject to situation- and environment-specific factors.

The objective of this study was to explore social functioning in schizophrenic patients who have suffered child sexual abuse (CSA) in comparison with those who have not suffered from it in a Spanish sample of 50 patients with schizophrenia or schizoaffective disorder. The Quality of Life (QOL) Scale, the Childhood Trauma Questionnaire (CTQ-SF), and the NEO Five Factor Inventory (NEO-FFI) were administered in this study. We found a CSA prevalence of 22% in our sample. Results showed that QOL global scores reduced by 9.34% at a statistically significant level ( p = .037) in sexually abused patients in comparison with those who did not report experiencing sexual abuse. Regression analysis in the QOL scales showed no differences in intrapsychic foundation scores or in the social relations scale. Scores in the instrumental role scale were reduced by 4.42 points in patients with CSA ( p = .009). Neither neuroticism nor extraversion results differ between the trauma group and those who did not suffer trauma. Clinical implications of these results are discussed.

Star fruit (SF) is a commonly available fruit produced and eaten in tropical and subtropical countries. Since 1993, various reports have described neurotoxicity after eating SF, but this clinical condition remains unfamiliar. We aimed to describe this clinical entity, the role of renal dysfunction in this disorder, treatment strategies, and prognosis of patients with SF intoxication. We conducted a search of PubMed and Google Scholar databases from 1993 to 2016. We included reports describing patients with a clear history of SF ingestion with acute symptoms. We described the demographic characteristics, reported SF intake, treatments used, and outcomes. We reviewed totally 126 patients (male:female = 1.5:1) from 33 articles with mean age 54.4 ± 11 (range: 30-84). The most common symptom was hiccups (65%), whereas confusion and seizure were the most common symptoms associated with mortality (42% and 61%, respectively). Pre-intoxication renal function also affected mortality. While there was no mortality in patients with normal renal function (NRF), the mortality of patients among reported cases with chronic renal insufficiency and end-stage renal disease undergoing dialysis were 36% and 27%, respectively. With the inclusion of patients reported to have NRF, the overall mortality was 24%. Consistently, the number of SF consumed was substantially higher in the patients with NRF than those with renal functional impairment. The most common treatment strategy was hemodialysis (59%). Patients with impaired renal function were at higher risks of SF intoxication. Severe neurologic symptoms mandate immediate medical intervention because of the association between their occurrence and high mortalities. Toxin removal through dialysis, rather than symptomatic relief, seems to be beneficial to patient survival. Early and continuous dialysis appears to alleviate severe symptoms and prevent symptom rebounds.

Despite numerous publications regarding nontoxic goiter (NTG) treatment and an increasing interest in patients' quality of life, few studies present the outcome of 131-I treatment from the patients' perspective. Our study's main aim was to verify whether there is any improvement in life quality following 131-I treatment. Thirty-five patients with NTG qualified to participate in the study. All patients completed a Thyroid-Related Health-Related Quality of Life (Thy-R-HRQoL) questionnaire created by us and the Medical Outcomes Study 36-item Short Form (SF-36), right before and 1 year after 131-I. We observed an improvement in six out of eight SF-36 and three out of seven Thy-R-HRQoL domains. In comparison with the control group, we observed worse results in two out of eight, prior to treatment, and one out of eight SF-36 afterward, as well as in all Thy-R-HRQoL domains. We did not find any correlation between improvement of Thy-R-HRQoL and SF-36 and goiter size reduction, except for Bodily Pain. There was also no correlation between improvement of SF-36 and Thy-R-HRQoL domains, and goiter size before treatment. The older the patient, the less noticeable improvement was observed in Physical and Social Functioning, and Vitality in SF-36, but age had no influence on the assessment by Thy-R-HRQoL. Radioiodine treatment improves life quality in patients with NTG. Use of the Health-Related Quality of Life questionnaire should be taken into consideration when evaluating life quality of patients with NTG. Relentless pursuit of maximal goiter size reduction in 131-I treatment is worth consideration. In our study, life quality improvement did not depend directly on the goiter size reduction. Life quality improvement after 131-I might not depend on initial goiter size, and for certain domains of SF-36 might be less clearly expressed in older patients.

The goal of this study was to evaluate the potential suitability of an artificial membrane composed of silk fibroin (SF) functionalized by different ratios of chitosan (CS) as a substrate for the stroma of the cornea. Keratocytes were cultured on translucent membranes made of SF and CS with different ratios. The biophysical properties of the silk fibroin and chitosan (SF/CS) membrane were examined. The SF/CS showed tensile strengths that increased as the CS concentration increased, but the physical and mechanical properties of chitosan-functionalized silk fibroin scaffolds weakened significantly compared with those of native corneas. The resulting cell scaffolds were evaluated using western blot in addition to light and electron microscopy. The cell attachment and proliferation on the scaffold were similar to those on a plastic plate. Keratocytes cultured in serum on SF/CS exhibited stellate morphology along with a marked increase in the expression of keratocan compared with identical cultures on tissue culture plastics. The biocompatibility was tested by transplanting the acellular membrane into rabbit corneal stromal pockets. There was no inflammatory complication detected at any time point on the macroscopic level. Taken together, these results indicate that SF/CS holds promise as a substrate for corneal reconstruction.

the purpose was to investigate how the obese person perceives their health in different areas of their life. the SF-36 instrument, which measures various dimensions (social and physical functioning, mental and physical health, bodily pain, limitations due to physical and/or emotional problems, vitality and general health), was applied to 224 patients. It was analyzed whether there were differences between gender, which were channeled to the treatment (surgical and nonsurgical) and the degree of obesity (overweight, obesity and morbid obesity). A descriptive analysis, Student t test, Anova and Tukey t test were used. significant differences (p < 0.05) were found in some dimensions, like tendency to feel tired, exhausted and feeling that their health has been and will continue to deterioration. Women had a worse social and emotional functioning than men; patients with gastric bypass reported more fatigue than patients with gastric band; in regards to the degree of obesity, those who had morbid obesity showed less physical functioning, more pain and worse overall health than those who were just obese. the perception of the obese patients was that their health had deteriorated. Women were more affected in social and emotional functioning than men.

Women are overrepresented among the group people suffering from long-term illness. In addition to their illness, suffering long-term sick leave leads to economical restraints as well social distress. There are gaps in our understanding of the challenges these women face. There is also lack of knowledge about how these challenges can be effectively addressed in rehabilitation. This deficiency is problematic from an ethical, justice and a caring perspective. In this study, changes in health-related quality of life (HRQoL) among women on long-term sick leave were investigated during and after participating in a rehabilitation programme combining two validated methods, Garden Therapy and Supported Employment (SE). The study also discusses difficulties in realising research related to vulnerable under-privileged people. From a population of 329 women who had reported their interest to participate, 245 were randomised to the programme. Of these 144 accepted participation in the research project and of these 123 women accepted to answer the SF-36 questionnaire. The participants were between 21 and 62 years with poor physical and mental health. They had received public financial support from <1 year to >10 years. The SF-36 measurement was carried out at baseline, after completion of Garden Therapy and after completion of SE. The results are based on data of respondents who participated at all the three occasions (n = 52). When comparing HRQoL baseline with the following occasions, the participants' General Health (GH), Vitality (VT), Social Functioning (SF) and mental health had improved significantly. The Four Leaf Clover (FLC) programme could be an appropriate method for reducing socially induced suffering. However, to conduct intervention studies where vulnerable persons are involved, it is off vital importance to consider whether the participants have the strength to complete the intervention. © 2015 Nordic College of Caring Science.

Cross-sectional relationships between physical activity and health have been explored extensively, but less is known about how physical activity changes with time in older people. The aim of this study was to assess baseline predictors of how objectively measured physical activity changes with time in older people. Longitudinal cohort study using data from the Physical Activity Cohort Scotland. A sample of community-dwelling older people aged 65 and over were recruited in 2009-2011, then followed up 2-3 years later. Physical activity was measured using Stayhealthy RT3 accelerometers over 7 days. Other data collected included baseline comorbidity, health-related quality of life (SF-36), extended Theory of Planned Behaviour Questionnaire and Social Capital Module of the General Household Survey. Associations between follow-up accelerometer counts and baseline predictors were analysed using a series of linear regression models, adjusting for baseline activity levels and follow-up time. Follow up data were available for 339 of the original 584 participants. The mean age was 77 years, 185 (55%) were female and mean follow up time was 26 months. Mean activity counts fell by between 2% per year (age < =80, deprivation decile 5-10) and 12% per year (age > 80, deprivation decile 5-10) from baseline values. In univariate analysis age, sex, deprivation decile, most SF-36 domains, most measures of social connectedness, most measures from the extended Theory of Planned Behaviour, hypertension, diabetes mellitus, chronic pain and depression score were significantly associated with adjusted activity counts at follow-up. In multivariate regression age, satisfactory friend network, SF-36 physical function score, and the presence of diabetes mellitus were independent predictors of activity counts at follow up after adjustment for baseline count and duration of follow up. Health status and social connectedness, but not extended Theory of Planned Behaviour measures, independently predicted changes in physical activity in community dwelling older people.

TM4SF5-Mediated Roles in the Development of Fibrotic Phenotypes

PubMed Central

Ryu, Jihye

2017-01-01

Transmembrane 4 L six family member 5 (TM4SF5) can form tetraspanin-enriched microdomains (TERMs) on the cell's surface. TERMs contain protein-protein complexes comprised of tetraspanins, growth factor receptors, and integrins. These complexes regulate communication between extracellular and intracellular spaces to control diverse cellular functions. TM4SF5 influences the epithelial-mesenchymal transition (EMT), aberrant multilayer cellular growth, drug resistance, enhanced migration and invasion, circulation through the bloodstream, tumor-initiation property, metastasis, and muscle development in zebrafish. Here, current data on TM4SF5's roles in the development of fibrotic phenotypes are reviewed. TM4SF5 is induced by transforming growth factor β1 (TGFβ1) signaling via a collaboration with epidermal growth factor receptor (EGFR) activation. TM4SF5, by itself or in concert with other receptors, transduces signals intracellularly. In hepatocytes, TM4SF5 expression regulates cell cycle progression, migration, and expression of extracellular matrix components. In CCl4-treated mice, TM4SF5, α-smooth muscle actin (α-SMA), and collagen I expression are observed together along the fibrotic septa regions of the liver. These fibrotic phenotypes are diminished by anti-TM4SF5 reagents, such as a specific small compound [TSAHC, 4′-(p-toluenesulfonylamido)-4-hydroxychalcone] or a chimeric antibody. This review discusses the antifibrotic strategies that target TM4SF5 and its associated protein networks that regulate the intracellular signaling necessary for fibrotic functions of hepatocytes.

To investigate whether aerobic capacity explains the level of self-reported physical activity, physical functioning, and participation and autonomy in daily living in persons with multiple sclerosis-related fatigue. A cross-sectional study. Sixty-two participants with multiple sclerosis-related fatigue. Aerobic capacity was measured with a leg ergometer and was expressed as maximal oxygen uptake (VO2max, in ml/kg/min). Physical activity was measured with the Physical Activity Scale for Individuals with Physical Disabilities (PASIPD), physical functioning with the Short Form 36 - physical functioning (SF36-pf), and participation and autonomy in daily living with the Impact on Participation and Autonomy questionnaire (IPA). Multiple regression analyses were performed, adjusted for potential confounders (gender, age, body mass index, educational level, and employment status). Mean maximal oxygen uptake (VO2max) was 23.9 ml/kg/min (standard deviation (SD) 6.3 ml/kg/min). There was no significant relationship between VO2max and physical activity (PASIPD): β = 0.320, 95% confidence interval (95% CI) = -0.109 to 0.749, R2 = 10.8%. Higher VO2max correlated with better physical functioning (SF36-pf): β = 1.527, 95% CI = 0.820-2.234, R2 = 25.9%, and was significantly related to IPA domains "autonomy indoors" (β = -0.043, 95% CI = -0.067 to -0.020, R2 = 20.6%), "autonomy outdoors" (β = -0.037, 95% CI = -0.062 to -0.012, R2 = 18.2%) and "social life and relationships" (β=-0.033, 95% CI = -0.060 to -0.007, R2 = 21.3%). Maximum aerobic capacity was severely reduced in persons with multiple sclerosis-related fatigue. This partly explains the limited physical functioning and restrictions in participation and autonomy indoors, outdoors and in social life and relationships in these persons.

Little is known about the independent associations of reward and stress within specific roles with multiple measures of mental health in an ethnically diverse community sample of midlife women. The objective of this study is to examine if (1) role reward (within each role and across roles) contributes directly to mental health and buffers the negative impact of role stress and (2) associations among role occupancy, role stress, and role reward and mental health vary by race/ethnicity. With separate logistic regression analysis, we investigated cross-sectional relationships between role stress and role reward with presence/absence of high depressive symptoms (Center for Epidemiologic Studies Depression Scale [CES-D≥16]), anxiety symptoms (feeling tense or nervous, irritable or grouchy, fearful for no reason, and heart pounding or racing total score≥4), or low social functioning (bottom 25th percentile of the Short-Form-36 [SF-36] social functioning subscale) in 2549 women participating in the third visit of the Study of Women's Health Across the Nation (SWAN), a longitudinal population-based study of menopause. High reward across roles attenuated the negative impact of role stress on social functioning but not on anxiety or depression. High reward marriage buffered the impact of marital stress on depression, and high reward mothering buffered the effect of maternal stress on depression and social functioning. Compared to Caucasians, Hispanics and Chinese with high stress across roles had better social functioning, and African American mothers had lower odds of high depressive symptoms. Role reward buffers the negative impact of stress on social functioning and depression, but not on anxiety. Minorities may respond to role stress by seeking social support.

Exposure to multiple disasters, both natural and technological, is associated with extreme stress and long-term consequences for older adults that are not well understood. In this article, we address age differences in health-related quality of life in older disaster survivors exposed to the 2005 Hurricanes Katrina and Rita and the 2010 BP Deepwater Horizon oil spill and the role played by social engagement in influencing these differences. Participants were noncoastal residents, current coastal residents, and current coastal fishers who were economically affected by the BP oil spill. Social engagement was estimated on the basis of disruptions in charitable work and social support after the 2005 hurricanes relative to a typical year before the storms. Criterion measures were participants' responses to the SF-36 Health Survey which includes composite indexes of physical (PCS) and mental (MCS) health. The results of logistic regressions indicated that age was inversely associated with SF-36 PCS scores. A reduction in perceived social support after Hurricane Katrina was also inversely associated with SF-36 MCS scores. These results illuminate risk factors that impact well-being among older adults after multiple disasters. Implications of these data for psychological adjustment after multiple disasters are considered. (Disaster Med Public Health Preparedness. 2017;11:90-96).

Effects of creative and social activity on the health and well-being of socially isolated older people: outcomes from a multi-method observational study.

Depression and social isolation affect one in seven people over 65 and there is increasing recognition that social isolation adversely affects long-term health. Research indicates that interventions, which promote active social contact, which encourage creativity, and which use mentoring, are more likely to positively affect health and well-being. The purpose of this study was to evaluate a complex intervention for addressing social isolation in older people, embodying these principles: The Upstream Healthy Living Centre. Mentors delivered a series of individually-tailored activities, with support tailing off over time. Two hundred and twenty-nine participants were offered the Geriatric Depression Scale, SF12 Health Quality of Life, and Medical Outcomes Social Support scale at baseline, then 6 months and 12 months post intervention. Semi-structured interviews were conducted with 26 participants, five carers and four referring health professionals to provide a deeper understanding of outcomes. Data were available for 172 (75%) participants at baseline, 72 (53% of those eligible) at 6 months and 51 (55%) at 12 months. Baseline scores indicated social isolation and high morbidity for mental and physical health. The intervention was successful in engaging this population (80% of referrals were engaged in some form of activity). At 6 months, there were significant improvements in SF12 mental component, and depression scores, but not in perceived physical health or social support. At 12 months, there were significant improvements in depression and social support and a marginally significant improvement in SF12 physical component (p = 0.06), but the SF12 mental component change was not maintained. The qualitative data showed that the intervention was well-received by participants. The data indicated a wide range of responses (both physical and emotional), including increased alertness, social activity, self-worth, optimism about life, and positive changes in health behaviour. Stronger, 'transformational' changes were reported by some participants. Individual tailoring seemed to be a key mediator of outcomes, as was overcoming barriers relating to transport and venues. Key processes underlying outcomes were the development of a positive group identity, and building of confidence/self-efficacy. The Upstream model provides a practical way of engaging socially isolated elderly people and generating social networks. The data suggest a range of psychosocial and physical health benefits. Although there are limitations in attributing causality in uncontrolled studies, the data seem to indicate a reversal of the expected downward trends in some aspects of participants' health, and suggest that this approach is worth further investigation.

Cornea endothelial cells (CEnCs) tissue engineering is a great challenge to repair diseased or damaged CEnCs and require an appropriate biomaterial to support cell proliferation and differentiation. Biomaterials for CEnCs tissue engineering require biocompatibility, tunable biodegradability, transparency, and suitable mechanical properties. Silk fibroin-based film (SF) is known to meet these factors, but construction of functionalized graft for bioengineering of cornea is still a challenge. Herein, lysophosphatidic acid (LPA) is used to maintain and increase the specific function of CEnCs. The LPA and SF composite film (LPA/SF) was fabricated in this study. Mechanical properties and in vitro studies were performed using a rabbit model to demonstrate the characters of LPA/SF. ATR-FTIR was characterized to identify chemical composition of the films. The morphological and physical properties were performed by SEM, AFM, transparency, and contact angle. Initial cell density and MTT were performed for adhesion and cell viability in the SF and LPA/SF film. Reverse transcription polymerase chain reactions (RT-PCR) and immunofluorescence were performed to examine gene and protein expression. The results showed that films were designed appropriately for CEnCs delivery. Compared to pristine SF, LPA/SF showed higher biocompatibility, cell viability, and expression of CEnCs specific genes and proteins. These indicate that LPA/SF, a new biomaterial, offers potential benefits for CEnCs tissue engineering for regeneration. PMID:29710848

Major depressive disorder remains one of the leading causes of disability in developed countries despite pharmacological and psychological treatments. Patients with major depression have poorer health-related quality of life than persons of the general population, or patients with chronic somatic illness. Improvement of health-related quality of life in depression is thus a pertinent treatment objective. Both high-frequency repetitive transcranial magnetic stimulation (rTMS) over the left dorsolateral prefrontal cortex and low-frequency rTMS over the right dorsolateral prefrontal cortex have shown their effectiveness in medication-resistant depression. However, the Health-related Quality of Life questionnaire remains under-utilized to assess the effectiveness of rTMS in research or in a routine clinical setting. Our study aims to investigate in an open label trial the efficacy of low-frequency rTMS over the right dorsolateral prefrontal cortex on health-related quality of life and clinical outcomes in medication-resistant depression. In a naturalistic trial, 33 unipolar and bipolar patients with medication-resistant depression were treated with daily low-frequency rTMS over the right dorsolateral prefrontal cortex for 4 weeks. Health-related quality of life was assessed using the SF-36 questionnaire. The SF-36 is a generic, self-administered, and worldwide-used questionnaire, consisting of 36 items describing eight health dimensions: physical functioning, social functioning, role-physical problems, role-emotional problems, mental health, vitality, bodily pain, and general health. Physical component summary and mental component summary scores were then obtained. Depression severity was assessed using the 21-item self-report Beck Depression Inventory. Anxiety severity was assessed using the State-Trait Anxiety Inventory. The SF-36, the Beck Depression Inventory and the State-Trait Anxiety Inventory were assessed before and after low-frequency rTMS. The effect of rTMS treatment on the SF-36 and the clinical outcome was evaluated for significance with the Wilcoxon two-tailed signed-rank test. The reliable change index (RCI) was calculated to determine clinically significant change in the eight dimension and composite scores of the SF-36 from pre-intervention to post-intervention, at the level of individual patients. Effect size (r) was then calculated, r values from 0.1 to 0.29, 0.3 to 0.49 and from 0.5 were considered as indicating small, medium and large effect sizes, respectively. Correlations between improvement in Health-related Quality of Life and improvement in the other rating scale scores were calculated using Spearman's correlation test. There were significant improvements of 37.6% in the mental health (P=0.018), 130 % in the role-emotional problem (P=0.045), 15.5% in the physical functioning (P=0.008), 110.6% in the role-physical problem (P=0.002), 22.4% in the bodily pain (P=0.013) dimensions, 6.1% in the Physical Component Score (P=0.043), and 22,5 % in the Beck Depression Inventory (P=0.002). Eighteen patients (54%) showed clinically significant improvement in one of the two composite scores after RCI calculation. Seven out of the eight SF-36 dimension scores and the two composite scores showed effect sizes ranging from 0.12 to 0.38, indicating small to moderate effect. Significant correlations were found between improvement in the Beck Depression Inventory and improvement in the Mental Component Score, the social functioning, the mental health, the general health, the vitality and the physical functioning dimensions.

Although Short Form (SF)-12 × 2® has been extensively studied and used as a valid measure of health-related quality of life in a variety of population groups, no systematic studies have described the reliability of the measure in patients with behavioral conditions or serious mental illness (SMI). We assessed the internal consistency, split-half reliability and annual test-retest correlations in a sample of 1587 participants with either a combination of physical and behavioral conditions or SMI. The Mosier's alpha was 0.70 for the Physical Composite Scale (PCS) and 0.69 for the Mental Health Composite Scale (MCS), indicating good internal consistency. We observed strong correlations between physical functioning, physical role and body pain scales (r = 0.55-0.56), and between social functioning, emotional role, and mental health (r = 0.53-0.58). We calculated split-half reliabilities to be 0.74 for physical functioning, 0.75 for physical role, 0.73 for emotional role and 0.65 for mental health respectively. We assessed the annual test-retest correlation using intraclass correlation (ICC) and found an ICC of 0.61 for PCS and 0.57 for MCS composite scores, adjusting for age, sex, race/ethnicity, and CRG. We found no decline in the correlations between baseline and the following study years until year 3. Our results encourage using SF-12v2® to assess health-related quality of life in the Medicaid population with combined physical and behavioral conditions or similar cohorts. The WIN study was registered with clinicaltrials.gov on April 22, 2015. NCT02440906 . Retrospectively registered.

To investigate the role of perceived neighborhood characteristics, socioeconomic status (SES) and rural residency in influencing the health status outcome of Egyptian patients with systemic lupus erythematosus (SLE). Eighty patients affected with SLE were consecutively included in this a single-center cross-sectional study from July, 2011 to July, 2013. Outcome measures included the Systemic Lupus Activity Questionnaire (SLAQ) score, the Medical Outcomes Study Short Form-36 Health Survey physical functioning score and Center for Epidemiologic Studies-Depression (CES-D score of ≥ 19 points). Multivariate logistic regression analyses were conducted. Results from multivariate logistic regression analyses, a separate adjusted model of each perceived neighborhood characteristic, indicate associations of worse perceived social cohesion with higher SLAQ scores (P < 0.01) and associations of worse perceived neighborhood aesthetics and safety with lower SF-36 physical functioning scores after adjusting for covariates (P < 0.01). Regarding the association of socioeconomic status and rural residency with health status outcomes, the results found association of poor socioeconomic status with the three health status outcome measures and association between rural residency and depression symptoms. Individuals had increased odds of depressive symptoms if they perceived worse neighborhood social cohesion (odds ratio [OR]: 2.14; CI: 1.42-2.80), if they perceived worse neighborhood safety (OR: 1.64; CI: 1.02-2.40) and if they perceived worse neighborhood aesthetic characteristics (OR: 2.79; CI: 1.84-3.38). Study findings indicate that poor socioeconomic status, rural residency and perceived neighborhood characteristics are associated with depression; worse perceived neighborhood aesthetics and safety are associated with lower SF-36 physical functioning, and worse neighborhood social cohesion is associated with higher disease activity among patients with SLE. © 2014 Asia Pacific League of Associations for Rheumatology and Wiley Publishing Asia Pty Ltd.

Although a number of validated health-related quality of life (HR-QOL) instruments exist for critical care populations, a standardised approach to assessing the HR-QOL of out-of-hospital cardiac arrest (OHCA) survivors has not been developed. We sought to compare the responses of 12-month OHCA survivors to three HR-QOL and functional recovery instruments, and assess instrument validity. The Victorian Ambulance Cardiac Arrest Registry invited 12-month OHCA survivors to participate in telephone follow-up between January 2011 and December 2015. Responders provided answers to the 12 Item Short Form Health Survey (SF-12), Three-Level EuroQol-5D (EQ-5D-3L) and the Glasgow Outcome Scale-Extended (GOSE). The SF-12 was also used to derive the SF-6D. Responses were used to assess the interpretability and construct validity of the instruments. A total of 1188 patients and proxies responded. Large ceiling effects were observed for the EQ-5D-3L (patients=46%, proxies=23%). Substantial variability was also observed in SF-6D responses for patients who reported full health according to the EQ-5D-3L. For patient responders, the strongest correlations were observed between the EQ-5D-3L index score and SF-6D (ρ=0.65, p<0.001), and between the SF-6D and SF-12 physical component (ρ=0.69, p<0.001). The distribution of the SF-6D and EQ-5D-3L differed significantly for patients reporting a lower or upper moderate GOSE outcome and lower or upper good recovery (p<0.001 for all comparisons). The EQ-5D-3L demonstrated limited interpretability due to the presence of ceiling effects. However, the measurement properties of the SF-12, SF-6D and GOSE suggest that these may be useful measures of HR-QOL and functional recovery in OHCA survivors. Copyright © 2016 Elsevier Ireland Ltd.

Socially anxious and control participants engaged in a social interaction with a confederate and then wrote about themselves or the other person (i.e., self-focused post-event processing [SF-PEP] vs. other-focused post-event processing [OF-PEP]) and completed several questionnaires. One week later, participants completed measures concerning their evaluation of their performance in the social interaction and the degree to which they engaged in post-event processing (PEP) during the week. Socially anxious individuals evaluated their performance in the social interaction more poorly than control participants, both immediately after and 1 week later. Socially anxious individuals assigned to the SF-PEP condition displayed fewer positive feelings about their performance compared to the socially anxious individuals in the OF-PEP condition as well as controls in either condition. Also, the trait tendency to engage in PEP moderated the effect of social anxiety on participants' evaluation of their performance in the interaction, such that high socially anxious individuals with high trait PEP scores evaluated themselves in the interaction more negatively at the later assessment. These results suggest that PEP and other self-evaluative processes may perpetuate the cycle of social anxiety. Copyright © 2011. Published by Elsevier Ltd.

Health-Related Quality of Life Among Chinese Patients With Rheumatoid Arthritis: The Predictive Roles of Fatigue, Functional Disability, Self-Efficacy, and Social Support.

PubMed

Gong, Guilan; Mao, Jing

2016-01-01

Health-related quality of life (HRQoL) is an important outcome measure in chronic diseases like rheumatoid arthritis (RA). However, there is a paucity of literature from mainland China on HRQoL and factors that influence it in people with RA. The aim of this study was to assess HRQoL and to determine which factors, based on the Wilson and Cleary model, contribute to the prediction of HRQoL among persons with RA in mainland China. A cross-sectional design was used. Persons with RA (N = 207) were recruited from the outpatient clinics of a university-affiliated hospital in central China. Participants responded to a demographic data questionnaire, the Medical Outcomes Study 36-Item Short Form Health Survey (SF-36), the Multidimensional Fatigue Inventory, the Health Assessment Questionnaire-Disability Index, the eight-item Arthritis Self-Efficacy Scale, and the Medical Outcomes Study Social Support Survey. Structural equation modeling was used to estimate the effects of factors from the Wilson and Cleary model on HRQoL. Scores on all SF-36 subscales were significantly lower in patients with RA compared with a general Chinese sample. Lower self-efficacy, greater fatigue, greater functional disability, lower social support, being unemployed, higher disease activity, more comorbidities, lower income level, being female, living in rural settings, and being older were directly or indirectly significantly and negatively associated with HRQoL; 67% of the total variance of HRQoL scores was explained. Patients with RA in mainland China experience impaired physical and mental health. Targeted and culturally sensitive interventions should be strengthened to improve the HRQoL of this population. Essentials in improving the HRQoL are enhancing self-efficacy, relieving fatigue, delaying the onset of disabilities, increasing social support, and controlling disease activity.

To investigate health anxiety and depressive symptoms in patients with fibromyalgia syndrome (FMS). Patients with FMS and healthy control subjects were recruited. All participants completed the Health Anxiety Inventory Short Form (HAI-SF) and Beck Depression Inventory (BDI). Pain was assessed in patients with FMS using the Fibromyalgia Impact Questionnaire (FIQ) and Visual Analogue Scale (VAS). This study involved 95 patients with FMS (15 male) and 95 healthy controls (17 male). Mean ± SD HAI-SF and BDI scores were significantly higher in patients with FMS = than in controls=. HAI-SF scores were 23.50 ± 10.78 and 9.38 ± 4.24 respectively; BDI scores were 18.64 ± 10.11 and 6.21 ± 4.05 respectively. There were highly significant correlations between FIQ and HAI-SF, FIQ and BDI, and HAI-SF and BDI. Patients with FMS had significantly higher HAI-SF and BDI scores than healthy controls. Psychiatric support is essential for patients with FMS. Treatment should include biological, psychological and social approaches. © The Author(s) 2015.

Yoga classes designed for women with premenstrual syndrome are available, but their efficacy is unclear. We investigated the effects of 12 weeks' yoga exercise (yoga intervention) on premenstrual symptoms in menstruating females in Taiwan. Sixty-four subjects completed the yoga intervention, and before and after the intervention filled out a structured self-report questionnaire about their demographics, personal lifestyle, menstrual status, baseline menstrual pain scores, premenstrual symptoms, and health-related quality of life. Of 64 subjects, 90.6% reported experiencing menstrual pain during menstruation. After the yoga intervention, subjects reported decreased use of analgesics during menstruation (p = 0.0290) and decreased moderate or severe effects of menstrual pain on work (p = 0.0011). The yoga exercise intervention was associated with the improvement of the scale of physical function (p = 0.0340) and bodily pain (p = 0.0087) of the SF-36, and significantly decreased abdominal swelling (p = 0.0011), breast tenderness (p = 0.0348), abdominal cramps (p = 0.0016), and cold sweats (p = 0.0143). Menstrual pain mitigation after yoga exercise correlated with improvement in six scales of the SF-36 (physical function, bodily pain, general health perception, vitality/energy, social function, mental health). Employers can educate female employees about the benefits of regular exercise such as yoga, which may decrease premenstrual distress and improve female employee health.

This study evaluated the correlations between spiritual beliefs and health-related quality of life (HRQOL) of hemodialysis (HD) patients in Taiwan. Participants had to complete two questionnaires: the 36-item Short Form Health Survey Questionnaire and the Royal Free Interview for Spiritual and Religious Beliefs. They were then divided into three groups according to their strength of spiritual beliefs-having no, weak, or strong beliefs. Demographic, clinical, and laboratory data among groups were compared. Correlations between spiritual beliefs and HRQOL were then determined by the analysis of covariance and the post hoc Scheffe tests. Six hundred thirty-three patients completed the study. There were more women in the group of patients with strong beliefs (P = 0.005) and more less-educated patients in the group of patients with weak beliefs (P = 0.005). Patients with no or with strong spiritual beliefs had higher role physical (P = 0.01) and social functioning (SF) (P = 0.001) scores than patients with weak beliefs. After adjustment for gender, age, marital status, education, comorbidities, and time on dialysis, patients with no or with strong spiritual beliefs were found to have higher SF scores (P = 0.02) than patients with weak beliefs. HD patients with no or strong spiritual beliefs had higher SF HRQOL than those with weak spiritual beliefs.

District policies were recently put into place in Indonesia prohibiting smoking in public spaces. This study sought to (1) assess participants' general knowledge of secondhand smoke (SHS) dangers; (2) assess participants' awareness of and specific knowledge of smoke-free (SF) policies; and (3) assess the extent to which such policies are socially enforced and gather examples of successful social enforcement. Qualitative in-depth interviews and focus group discussions were conducted in Bogor and Palembang cities with both community members and key informants such as government officials, non-government agency staff, religious leaders and health workers. Participants in both Palembang and Bogor find SF policy important. Although there was awareness of SHS dangers and SF policies, accurate knowledge of the dangers and an in-depth understanding of the policies varied. There was a high level of support for the SF policies in both cities among both smokers and non-smokers. Many participants did have experience asking a smoker not to smoke in an area where it was restricted, even if their comfort in doing so varied. There was, however, a higher level of comfort in telling smokers to stop or to move away from pregnant women and children. Hesitation to socially enforce the policies was especially present when asking men of status and/or community leaders to stop smoking, but overall participants felt they could comfortably ask someone to obey the law. Palembang and Bogor may be evolving towards creating social norms in support of prohibiting smoking in public spaces. If provided with more support from government and law officials, such as government officials themselves promoting the policies and demonstrating compliance, and renewed efforts to promote and enforce policies in general were made, Indonesians in these cities may feel more confident protecting non-smokers from SHS.

Nagasaka, Shinya; Iwasaki, Takumi; Okano, Tomoko

We analyzed the phenotype and function of bone marrow-derived dendritic cells (DCs) induced in vitro without using any serum during the late stage of cultivation. These 'serum-free' DCs (SF-DCs) possessed the ability to induce T cell proliferation as well as antibody responses, indicating that they were functional DCs. Surprisingly, the SF-DCs akin to semi-mature DCs in terms of both phenotypic and functional characteristics. The SF-DCs did not produce IL-12 but produced large amounts of IL-23 following lipopolysaccharide stimulation. The antigen-specific production of IL-17 by CD4{sup +} T cells co-cultured with OVA-loaded SF-DCs was significantly higher than that with OVA-loaded conventionalmore » DCs. These results suggest that SF-DCs tend to produce IL-23 and can consequently induce the IL-17 producing CD4{sup +} T cells. The semi-mature DC-like cells reported here will be useful vehicles for DC immunization and might contribute to studies on the possible involvement of semi-mature DCs in Th17 cell differentiation.« less

Drosophila I-R hybrid dysgenesis is associated with catastrophic meiosis and abnormal zygote formation.

PubMed

2010-10-15

The Drosophila I-R type of hybrid dysgenesis is a sterility syndrome (SF sterility) associated with the mobilization of the I retrotransposon in female germ cells. SF sterility results from a maternal-effect embryonic lethality whose origin has remained unclear since its discovery about 40 years ago. Here, we show that meiotic divisions in SF oocytes are catastrophic and systematically fail to produce a functional female pronucleus at fertilization. As a consequence, most embryos from SF females rapidly arrest their development with aneuploid or damaged nuclei, whereas others develop as non-viable, androgenetic haploid embryos. Finally, we show that, in contrast to mutants affecting the biogenesis of piRNAs, SF egg chambers do not accumulate persistent DNA double-strand breaks, suggesting that I-element activity might perturb the functional organization of meiotic chromosomes without triggering an early DNA damage response.

This study aims to evaluate published randomized controlled trials (RCTs) of Chinese Herbal Medicine (CHM) improving health-related quality of life (HRQL) in hypertensive patients that employ the Short-Form 36-Item Health questionnaire (SF-36) as an outcome measure. Five electronic databases were searched up to October 2013 to identify RCTs of CHM for hypertension. The primary outcome was SF-36. Trial selection, data extraction, methodological quality assessment, and data analyses were conducted according to the Cochrane handbook. Eleven RCTs with total of 1043 participants were identified. The majority of the included trials were assessed to be of poor methodological quality and high clinical heterogeneity. Meta-analysis shows a significant improvement both in physical component summary (PCS) measure and mental component summary (MCS) measure of SF-36, with physical functioning (WMD=8.54[5.34, 11.74], p<0.001), role physical (WMD=13.32[7.03, 19.61], p<0.001), bodily pain (WMD=10.53[6.46, 14.60], p<0.001), general health (WMD=-5.56[2.09, 9.02], p<0.001), vitality (WMD=6.84[4.33, 9.53], p<0.001), social functioning (WMD=7.50[2.63, 12.36], p<0.001), role emotional (WMD=12.06[4.45, 19.68], p<0.001) and mental health (WMD=-5.68[2.90, 8.47], p<0.001). CHM can also decrease systolic blood pressure (WMD=-4.45 [-6.71, -2.19], p<0.001) and relieve symptoms related to hypertension. CHM appears to have beneficial effects on improvement of HRQL in hypertensive patients. However, the findings should be interpreted with caution due to the poor methodological quality and high clinical heterogeneity of the included trials. Further clinical trials should be carried out to provide more reliable evidence. Copyright © 2015 Elsevier Ltd. All rights reserved.

The evidence on the effect of secondhand smoke (SHS) on Health Related Quality of Life (HRQoL) is limited. We examined the relation between SHS and HRQoL among Chinese in Hong Kong. Adult never smokers from a probability sample of three cross-sectional waves (2010, 2012, 2013) of The Hong Kong Family and Health Information Trends Survey who completed the Cantonese-version of Short-Form 12 Health Survey Questionnaire (SF12v2) were included in the data analysis conducted in 2014. Models were used to examine associations of SHS with SF12 domains and summary scores of Physical (PCS12) and Mental Component (MCS12) with subgroups analysis by SHS locations. After adjustments, SHS was associated with lower scores on all SF12 domains except physical functioning. PCS12 (regress coefficient=-0.76, 95% CI -1.34 to -0.17) and MCS12 (regress coefficient=-1.35, 95% CI -2.06 to -0.64) were lower in those with SHS exposure than those non-exposed. Those exposed to SHS in outdoor public places had lower scores on most SF12 domains and PSC12 and MCS12. SHS exposure in one's home and workplace was associated with lower scores on role physical, body pain and role emotional while SHS exposure in friends' homes was additionally associated with lower social functioning and mental health scores. Lower MCS12 was associated with SHS exposure at all locations except one's home. Our study showed that SHS exposure, particularly in outdoor public places, was associated with decreased HRQoL. It can provide new evidence for stronger smoke-free policies on public places and promoting smoke-free homes. Published by the BMJ Publishing Group Limited.

To investigate the prevalence of musculoskeletal pain and its impact on health-related quality of life (HRQoL) in workers of Fort Prajaksilapakom Hospital. A cross-sectional study was conducted. Participants completed self-reported questionnaires requesting demographic data and report ofpain symptoms occurring within the last one month. In addition, the HRQoL questionnaire (Thai SF-36v2) was used to study the SF-36v2 score. Musculoskeletal pain was divided into five groups: (1) no pain, 2) pain at one site, 3) pain at two sites, 4) pain at three sites and 5) pain at four sites. The association between the SF-36v2 score and mnusculoskeletal pain was evaluated using multivariable linear regression analysis. Of 726 hospital workers, 485 (66.8%) participated in the present study. The majority of participants were female (65.3%) and comprised non-health care providers (56.3%) with a mean age of 37 +/- 11.5 years (range: 20-59). The prevalence of musculoskeletal pain during the last one month was 77.0%. Musculoskeletal pain was mostly reported at the lower extremities (50.8%),followed by low back (48.2), the neck (40.5%) and the upper extremities (33.0%). Multiple sites pain (pain at more than one site) was 51%. Each subscale score of the Thai SF-36v2 was significantly lower in participants with pain than in those without pain (physical functioning; p<0.001, physical role; p = 0.001, bodily pain; p<0.001, general health; p<0.001, vitality; p<0.001, social functioning; p = 0.02, emotion role; p = 0.003 and mental health; p<0.001). Multiple pain sites were more likely to be associated with lower HRQoL. The present study showed the high prevalence of musculoskeletal pain and negative impact on HRQoL in workers ofFort Prajaksilapakom Hospital. The number of sites of musculoskeletal pain was associated with a reduction in the quality oflife.

An examination of structure-function claims in dietary supplement advertising in the U.S.: 2003-2009.

PubMed

Avery, Rosemary J; Eisenberg, Matthew D; Cantor, Jonathan H

2017-04-01

Dietary supplement advertising cannot claim a causal link between the product and the treatment, prevention, or cure of a disease unless manufacturers seek approval from the FDA for a health claim. Manufacturers can make structure-function (S-F) claims without FDA approval linking a supplement to a body function or system using words such as "may help" or "promotes." These S-F claims are examined in this study in order to determine whether they mimic health claims for which the FDA requires stricter scientific evidence. Data include S-F claims in supplement advertisements (N=6179) appearing in US nationally circulated magazines (N=137) from 2003 to 2009. All advertisements were comprehensively coded for S-F claims, seals of approval, and other claims of guarantee. S-F claims associate supplements with a wide variety of health conditions, many of which are serious diseases and/or ailments. A significant number of the specific verbs used in these S-F claims are indicative of disease treatment/cure effects, thereby possibly mimicking health claims to the average consumer. The strength of the clinical associations made are largely unsubstantiated in the medical literature. Claims that a product is "scientifically proven" or "guaranteed" were largely unsubstantiated by clinical literature. Ads carrying externally validating seals of approval were highly prevalent. S-F claims that strongly mimic FDA-prohibited health claims are likely to create confusion in interpretation and possible public health concerns are discussed. Copyright © 2017 Elsevier Inc.

LUMINOSITY FUNCTIONS OF SPITZER-IDENTIFIED PROTOSTARS IN NINE NEARBY MOLECULAR CLOUDS

DOE Office of Scientific and Technical Information (OSTI.GOV)

Kryukova, E.; Megeath, S. T.; Allen, T. S.

2012-08-15

We identify protostars in Spitzer surveys of nine star-forming (SF) molecular clouds within 1 kpc: Serpens, Perseus, Ophiuchus, Chamaeleon, Lupus, Taurus, Orion, Cep OB3, and Mon R2, which combined host over 700 protostar candidates. These clouds encompass a variety of SF environments, including both low-mass and high-mass SF regions, as well as dense clusters and regions of sparsely distributed star formation. Our diverse cloud sample allows us to compare protostar luminosity functions in these varied environments. We combine near- and mid-infrared photometry from the Two Micron All Sky Survey and Spitzer to create 1-24 {mu}m spectral energy distributions (SEDs). Usingmore » protostars from the c2d survey with well-determined bolometric luminosities, we derive a relationship between bolometric luminosity, mid-IR luminosity (integrated from 1-24 {mu}m), and SED slope. Estimations of the bolometric luminosities for protostar candidates are combined to create luminosity functions for each cloud. Contamination due to edge-on disks, reddened Class II sources, and galaxies is estimated and removed from the luminosity functions. We find that luminosity functions for high-mass SF clouds (Orion, Mon R2, and Cep OB3) peak near 1 L{sub Sun} and show a tail extending toward luminosities above 100 L{sub Sun }. The luminosity functions of the low-mass SF clouds (Serpens, Perseus, Ophiuchus, Taurus, Lupus, and Chamaeleon) do not exhibit a common peak, however the combined luminosity function of these regions peaks below 1 L{sub Sun }. Finally, we examine the luminosity functions as a function of the local surface density of young stellar objects. In the Orion molecular clouds, we find a significant difference between the luminosity functions of protostars in regions of high and low stellar density, the former of which is biased toward more luminous sources. This may be the result of primordial mass segregation, although this interpretation is not unique. We compare our luminosity functions to those predicted by models and find that our observed luminosity functions are best matched by models that invoke competitive accretion, although we do not find strong agreement between the high-mass SF clouds and any of the models.« less

Teleaudiology: efficacy assessment of an online social network as a support tool for parents of children candidates for cochlear implant.

To assess the efficacy of an online social network as a support for parents of children with hearing impairment. Twenty-two mothers, randomly divided into experimental (n=11) and control (n=11) groups, filled in an online form containing the Parental Stress Index - Short Form (PSI-SF). Only the experimental group had access to the "Babies' Portal" social network. Both groups filled in the online form once again 3 months after the first assessment, for evaluating the use and participation in the social network. The posts on the social network were rated by two independent raters regarding themes and mechanisms of self-help. No difference was observed in mean PSI-SF scores between the groups for both assessments. Intragroup analysis showed no difference for total and subscale results of PSI-SF between the two data collected for both groups except for the "Defensive Response" subscale, in which a decrease was observed in the score for the control group. The most frequent posting themes were related to personal information and expressions of religious beliefs. Regarding self-help mechanisms, a higher frequency of exchanging experiences and gratitude expressions was observed. Participants in the experimental group stated they would have liked to participate more frequently in the social network as they considered this tool important because of the exchange of information and experience with other mothers and hearing health-care professionals. The posts and the assessment of participants indicated the potential of this network to support parents of children with hearing impairment.

Pandemic is a typical spreading phenomenon that can be observed in the human society and is dependent on the structure of the social network. The Susceptible-Infective-Recovered (SIR) model describes spreading phenomena using two spreading factors; contagiousness (β) and recovery rate (γ). Some network models are trying to reflect the social network, but the real structure is difficult to uncover. We have developed a spreading phenomenon simulator that can input the epidemic parameters and network parameters and performed the experiment of disease propagation. The simulation result was analyzed to construct a new marker VRTP distribution. We also induced the VRTP formula for three of the network mathematical models. We suggest new marker VRTP (value of recovered on turning point) to describe the coupling between the SIR spreading and the Scale-free (SF) network and observe the aspects of the coupling effects with the various of spreading and network parameters. We also derive the analytic formulation of VRTP in the fully mixed model, the configuration model, and the degree-based model respectively in the mathematical function form for the insights on the relationship between experimental simulation and theoretical consideration. We discover the coupling effect between SIR spreading and SF network through devising novel marker VRTP which reflects the shifting effect and relates to entropy.

Abstract The aim of this study was to investigate if discrete wavelet decomposition provides additional insight into resting-state processes through the analysis of functional connectivity within specific frequency ranges within the default mode network (DMN) that may be affected by mild traumatic brain injury (mTBI). Participants included 32 mTBI patients (15 with postconcussive syndrome [PCS+] and 17 without [PCS−]). mTBI patients received resting-state functional magnetic resonance imaging (rs-fMRI) at acute (within 10 days of injury) and chronic (6 months postinjury) time points and were compared with 31 controls (healthy control [HC]). The wavelet decomposition divides the time series into multiple frequency ranges based on four scaling factors (SF1: 0.125–0.250 Hz, SF2: 0.060–0.125 Hz, SF3: 0.030–0.060 Hz, SF4: 0.015–0.030 Hz). Within each SF, wavelet connectivity matrices for nodes of the DMN were created for each group (HC, PCS+, PCS−), and bivariate measures of strength and diversity were calculated. The results demonstrate reduced strength of connectivity in PCS+ patients compared with PCS− patients within SF1 during both the acute and chronic stages of injury, as well as recovery of connectivity within SF1 across the two time points. Furthermore, the PCS− group demonstrated greater network strength compared with controls at both time points, suggesting a potential compensatory or protective mechanism in these patients. These findings stress the importance of investigating resting-state connectivity within multiple frequency ranges; however, many of our findings are within SF1, which may overlap with frequencies associated with cardiac and respiratory activities.

A multi-centre randomised controlled trial of rehabilitation aimed at improving outdoor mobility for people after stroke: Study protocol for a randomised controlled trial

PubMed Central

2012-01-01

Background Up to 42% of all stroke patients do not get out of the house as much as they would like. This can impede a person’s quality of life. This study is testing the clinical effectiveness and cost effectiveness of a new outdoor mobility rehabilitation intervention by comparing it to usual care. Methods/design This is a multi-centre parallel group individually randomised, controlled trial. At least 506 participants will be recruited through 15 primary and secondary care settings and will be eligible if they are over 18 years of age, have had a stroke and wish to get out of the house more often. Participants are being randomly allocated to either the intervention group or the control group. Intervention group participants receive up to 12 rehabilitation outdoor mobility sessions over up to four months. The main component of the intervention is repeated practice of outdoor mobility with a therapist. Control group participants are receiving the usual intervention for outdoor mobility limitations: verbal advice and provision of leaflets provided over one session. Outcome measures are being collected using postal questionnaires, travel calendars and by independent assessors. The primary outcome measure is the Social Function domain of the SF36v2 quality of life assessment six months after recruitment. The secondary outcome measures include: functional ability, mobility, the number of journeys (monthly travel diaries), satisfaction with outdoor mobility, mood, health-related quality of life, resource use of health and social care. Carer mood information is also being collected. The mean Social Function score of the SF-36v2 will be compared between treatment arms using a multiple membership form of mixed effects multiple regression analysis adjusting for centre (as a fixed effect), age and baseline Social Function score as covariates and therapist as a multiple membership random effect. Regression coefficients and 95% confidence intervals will be presented. Discussion This study protocol describes a pragmatic randomised controlled trial that will hopefully provide robust evidence of the benefit of outdoor mobility interventions after stroke for clinicians working in the community. The results will be available towards the end of 2012. Trial registration ISRCTN58683841 PMID:22721452

Obstructive sleep apnea syndrome (OSAS) is a common disorder defined by repeated episodes of airflow cessation (apneas)leading to arterial hypoxemia and sleep disruption. OSAS has been associated with increased morbidity, mortality and diminished quality of life so far. This cross-sectional study aimed to assess the impact of OSAS on patients' Quality of Life, as measured by the Medical Outcomes Study Short Form-36 (SF-36). Two hundred and forty five subjects referred to the sleep laboratory and underwent full polysomnography overnight. Prior to sleep study onset, we registered height and weight, medical history, smoking habit, drug consumption. Afterwards, each patient completed the SF-36. Eighty subjects not diagnosed with sleep apnea [apnea hypopnea index (AHI < 5)] were excluded. Therefore, 165 subjects (121 male and 44 female) remained. Statistical analysis revealed that in patients with respiratory disturbance index (RDI) ≥ 15, (n = 115), RDI was independently associated with lower performance in role limitations due to physical problems (p = 0.005). Additionally, RDI was the only factor associated with decreased vitality (p = 0.014) and mental health scores (p = 0.047). In the same patient subgroup, body mass index (BMI) and age were associated with poorer scores in physical functioning (p < 0.001 and p = 0.003, respectively). BMI was an independent clinical predictor of worse scores in bodily pain (p = 0.006) general health (p = 0.006), social functioning (p = 0.025) and role limitations due to emotional problems (p = 0.004).

The interfacial shear strength between different layers in multilayered structures of layer-by-layer (LbL) microcapsules is a crucial mechanical property to ensure their robustness. In this work, we investigated the interfacial shear strength of modified silk fibroin ionomers utilized in LbL shells, an ionic-cationic pair with complementary ionic pairing, (SF)-poly-l-glutamic acid (Glu) and SF-poly-l-lysine (Lys), and a complementary pair with partially screened Coulombic interactions due to the presence of poly(ethylene glycol) (PEG) segments and SF-Glu/SF-Lys[PEG] pair. Shearing and adhesive behavior between these silk ionomer surfaces in the swollen state were probed at different spatial scales and pressure ranges by using functionalized atomic force microscopy (AFM) tips as well as functionalized colloidal probes. The results show that both approaches were consistent in analyzing the interfacial shear strength of LbL silk ionomers at different spatial scales from a nanoscale to a fraction of a micron. Surprisingly, the interfacial shear strength between SF-Glu and SF-Lys[PEG] pair with partially screened ionic pairing was greater than the interfacial shear strength of the SF-Glu and SF-Lys pair with a high density of complementary ionic groups. The difference in interfacial shear strength and adhesive strength is suggested to be predominantly facilitated by the interlayer hydrogen bonding of complementary amino acids and overlap of highly swollen PEG segments.

The objective of this study was twofold: 1) to confirm the hypothetical eight scales and two-component summaries of the questionnaire Short Form 36 Health Survey (SF-36), and 2) to evaluate the performance of two alternative measures to the original physical component summary (PCS) and mental component summary (MCS). We performed principal component analysis (PCA) based on 35 items, after optimal scaling via multiple correspondence analysis (MCA), and subsequently on eight scales, after standard summative scoring. Item-based summary measures were planned. Data from the European Community Respiratory Health Survey II follow-up of 8854 subjects from 25 centers were analyzed to cross-validate the original and the novel PCS and MCS. Overall, the scale- and item-based comparison indicated that the SF-36 scales and summaries meet the supposed dimensionality. However, vitality, social functioning, and general health items did not fit data optimally. The novel measures, derived a posteriori by unit-rule from an oblique (correlated) MCA/PCA solution, are simple item sums or weighted scale sums where the weights are the raw scale ranges. These item-based scores yielded consistent scale-summary results for outliers profiles, with an expected known-group differences validity. We were able to confirm the hypothesized dimensionality of eight scales and two summaries of the SF-36. The alternative scoring reaches at least the same required standards of the original scoring. In addition, it can reduce the item-scale inconsistencies without loss of predictive validity.

Association between wellness coaching and changes in health-related quality of life over 1 year and 2 years was assessed. Difference-in-differences analysis of covariance assessed association between coaching and change in 8-item short-form health survey (SF-8) summary scores. Ordered logistic models assessed coaching and change in SF-8 individual domain scores. This was a case-control study. Participants in at least one coaching program were more likely to have increases in social functioning after 1 year and less likely to have increases in role physical after 2 years. Participants in nutrition coaching had more positive change in mental component summary scores after 1 year. Participants in stress management had more negative change in mental component summary scores after 1 year and after 2 years and had more negative change in physical component summary scores after 2 years. Findings were mixed regarding association between coaching and change in health-related quality of life.

The objective of this study is to compare the efficacy of mature mud pack and hot pack therapies on patients with knee osteoarthritis. This study was designed as a prospective, randomized-controlled, and single-blinded clinical trial. Twenty-seven patients with clinical and radiologic evidence of knee osteoarthritis were randomly assigned into two groups and were treated with mature mud packs (n 15) or hot packs (n=12). Patients were evaluated for pain [based on the visual analog scale (VAS)], function (WOMAC, 6 min walking distance), quality of life [Short Form-36 (SF-36)], and serum levels of tumor necrosis factor-alpha (TNF-α), interleukin-6 (IL-6), and insulin-like growth factor-1 (IGF-1) at baseline, post-treatment, and 3 and 6~months after treatment. The mud pack group shows a significant improvement in VAS, pain, stifness, and physical function domains of WOMAC. The difference between groups of pain and physical activity domains is significant at post-treatment in favor of mud pack. For a 6 min walking distance, mud pack shows significant improvement, and the difference is significant between groups in favor of mud pack at post-treatment and 3 and 6 months after treatment. Mud pack shows significant improvement in the pain subscale of SF-36 at the third month continuing until the sixth month after the treatment. Significant improvements are found for the social function, vitality/energy, physical role disability, and general health subscales of SF-36 in favor of the mud pack compared with the hot pack group at post-treatment. A significant increase is detected for IGF-1 in the mud pack group 3 months after treatment compared with the baseline, and the difference is significant between groups 3 months after the treatment. Mud pack is a favorable option compared with hotpack for pain relief and for the improvement of functional conditions in treating patients with knee osteoarthritis.

A systematic study of stacking fault energy (γ(SF)) resulting from induced alias shear deformation has been performed by means of first-principles calculations for dilute Ni-base superalloys (Ni(23)X and Ni(71)X) for various alloying elements (X) as a function of temperature. Twenty-six alloying elements are considered, i.e., Al, Co, Cr, Cu, Fe, Hf, Ir, Mn, Mo, Nb, Os, Pd, Pt, Re, Rh, Ru, Sc, Si, Ta, Tc, Ti, V, W, Y, Zn, and Zr. The temperature dependence of γ(SF) is computed using the proposed quasistatic approach based on a predicted γ(SF)-volume-temperature relationship. Besides γ(SF), equilibrium volume and the normalized stacking fault energy (Γ(SF) = γ(SF)/Gb, with G the shear modulus and b the Burgers vector) are also studied as a function of temperature for the 26 alloying elements. The following conclusions are obtained: all alloying elements X studied herein decrease the γ(SF) of fcc Ni, approximately the further the alloying element X is from Ni on the periodic table, the larger the decrease of γ(SF) for the dilute Ni-X alloy, and roughly the γ(SF) of Ni-X decreases with increasing equilibrium volume. In addition, the values of γ(SF) for all Ni-X systems decrease with increasing temperature (except for Ni-Cr at higher Cr content), and the largest decrease is observed for pure Ni. Similar to the case of the shear modulus, the variation of γ(SF) for Ni-X systems due to various alloying elements is traceable from the distribution of (magnetization) charge density: the spherical distribution of charge density around a Ni atom, especially a smaller sphere, results in a lower value of γ(SF) due to the facility of redistribution of charges. Computed stacking fault energies and the related properties are in favorable accord with available experimental and theoretical data.

The actions of prolactin (PRL) are mediated by both long (LF) and short isoforms (SF) of the PRL receptor (PRLR). Here, we report on a genetic and functional analysis of the porcine PRLR (pPRLR) SF. Three single nucleotide polymorphisms (SNPs) within exon 11 of the pPRLR-SF give rise to four amino acid haplotypes of the intracellular domain. We identified the dimorphic insertion of a short interspersed repetitive DNA element (PRE-1) along with 32 SNPs and four other insertion/deletion sites within the 3' untranslated region (UTR) of pPRLR-SF. The PRE-1 element reduced protein translation in vitro by 75%, whereas the combination of 10 SNPs and one insertion/deletion decreased translation by 50%. Full-length cDNAs for all four haplotypes of pPRLR-SF were cloned behind the elongation factor 1-alpha promoter and functionally analyzed in vitro. None of the haplotypes could initiate transcription from the ß-casein promoter, whereas all four were dominant negatives against PRL-activation of the pPRLR-LF. Two of the haplotypes completely inhibited pPRLR-LF activity at a four-fold excess, whereas the others required a six-fold excess to impart the same effect. The ligand binding affinities of the pPRLR-SF haplotypes did not differ. Expression of the pPRLR-SF increased linearly during gestation in the endometrium and was hormonally regulated in a tissue-specific manner in the mammary glands and uterus. In conclusion, we identified a PRE-1 and other SNPs in the pPRLR-SF 3' UTR that reduce protein expression and four haplotypes of the pPRLR-SF that suppress pPRLR-LF signaling and may differentially impact the phenotypic effects of PRL in vivo. © 2013 Stichting International Foundation for Animal Genetics.

Different equation-of-motion coupled cluster methods with different reference functions: The formyl radical

The doublet and quartet excited states of the formyl radical have been studied by the equation-of-motion (EOM) coupled cluster (CC) method. The Sz spin-conserving singles and doubles (EOM-EE-CCSD) and singles, doubles, and triples (EOM-EE-CCSDT) approaches, as well as the spin-flipped singles and doubles (EOM-SF-CCSD) method have been applied, subject to unrestricted Hartree-Fock (HF), restricted open-shell HF, and quasirestricted HF references. The structural parameters, vertical and adiabatic excitation energies, and harmonic vibrational frequencies have been calculated. The issue of the reference function choice for the spin-flipped (SF) method and its impact on the results has been discussed using the experimental data and theoretical results available. The results show that if the appropriate reference function is chosen so that target states differ from the reference by only single excitations, then EOM-EE-CCSD and EOM-SF-CCSD methods give a very good description of the excited states. For the states that have a non-negligible contribution of the doubly excited configurations one is able to use the SF method with such a reference function, that in most cases the performance of the EOM-SF-CCSD method is better than that of the EOM-EE-CCSD approach.

The performance of the second-order spin-flip constricted variational density functional theory (SF-CV(2)-DFT) for the calculation of the exchange coupling constant (J) is assessed by application to a series of triply bridged Cu(II) dinuclear complexes. A comparison of the J values based on SF-CV(2)-DFT with those obtained by the broken symmetry (BS) DFT method and experiment is provided. It is demonstrated that our methodology constitutes a viable alternative to the BS-DFT method. The strong dependence of the calculated exchange coupling constants on the applied functionals is demonstrated. Both SF-CV(2)-DFT and BS-DFT affords the best agreement with experiment for hybrid functionals.

This study was aimed to investigate the effects of an exercise trial on self-esteem, self-concept and quality of life in patients with fibromyalgia and to evaluate whether improvements in psychological distress were related to changes in physical functioning. Twenty-eight women with a primary diagnosis of fibromyalgia were randomized to a usual care control group or to a 12-week supervised training programme consisting of 3 weekly sessions of aerobic, strengthening and flexibility exercises. Outcomes were physical functioning (Fibromyalgia Impact Questionnaire (FIQ), lower-body strength and flexibility) and psychological functioning (SF-36, Rosenberg self-esteem scale and Erdmann self-concept scale). Outcomes were measured at study entry and at the end of the intervention. Compared to the control group, statistically significant improvements in self-esteem, self-concept, FIQ, physical functioning, role physical, bodily pain, vitality, role emotional, social functioning, mental health, isometric strength, muscular endurance and flexibility were evident in the exercise group at the end of treatment. Self-esteem and self-concept scores were correlated positively with role emotional, mental health and the mental component summary of SF-36 and were negatively correlated to FIQ scores. No significant correlation existed between self-esteem or self-concept and isometric strength, muscular endurance or flexibility. Our results highlight the need for a broader array of physical and mental outcomes and the importance of examining patient's perceptions in future research therapies.

The present research aimed at studying the psychometric properties of the Mental Health Continuum–Short Form (MHC–SF; Keyes, 2005) in a sample of 1,300 Argentinean adults (50% males; 50% females). Their mean age was 40.28 years old (SD = 13.59). The MHC–SF is a 14 item test that assesses three components (i.e., emotional, social, and psychological) of well-being. Convergent and divergent evidence of construct validity was assessed by conducting confirmatory factor analysis, cross-validation, factorial invariance, and correlations with external criteria. Internal consistency was studied using Cronbach’s alphas. Results indicated an adequate fit of a three-dimensional model. This structure was also confirmed, and was invariant throughout sex and age. The emotional well-being scores converged with life satisfaction and positive affect measures; the psychological well-being scale had a positive association with the presence of meaning in life; and the social well-being scores showed a positive and strong correlation with an external measure of well-being. Also, all scores were negatively associated with negative affect, search of meaning in life, and presence of depression symptoms. Internal consistency was .89 for the MHC–SF. Furthermore, the findings supported the two - continua model of mental health. PMID:28344677

Many factors have been suggested to contribute to sexual dysfunction (SD) in multiple sclerosis (MS) patients, but the research on their impact on sexual functioning (SF) and sexual quality of life (SQoL) remains scant. The aim of this study was to investigate correlates of SF and SQoL in MS patients, as well as possible gender differences. 204 MS patients were interviewed, completed the questionnaires, and underwent neurological assessment. Primary outcome measures included the International Index of Erectile Function, the Female Sexual Function Questionnaire, the Sexual Quality of Life Questionnaire, the Beck Depression Inventory, and the Expanded Disability Status Scale. The course and duration of the disease did not predict patients' SF. Negative correlations were found for brainstem symptoms with orgasmic function and overall satisfaction in men and between cognitive functioning and the partner domain in women. Interestingly, brainstem symptoms correlated positively with the arousal domain in women. More than half (52.1%) of patients fulfilled Beck Depression Inventory criteria for depression, and these patients showed more SD than nondepressive individuals. The strongest negative correlations with depressive symptoms were found for desire, erectile function, and overall satisfaction with sexual life in men and for orgasm and sexual enjoyment in women. Deterioration in particular domains of SF was clearly related with diminished SQoL. The main gender difference was a strong influence of decreased desire on SQoL in women and no such correlation in men. Negative assessment of the relationship with partner significantly affected all domains of SF and SQoL in MS women and the desire domain in MS men. Several correlates of SF in MS patients were found. The role of brainstem symptoms needs further investigation. Clinicians should pay close attention to depressive symptoms and relationship factors in MS patients who suffer from SD. © 2014 International Society for Sexual Medicine.

Open repair for infra-renal abdominal aortic and iliac artery aneurysms (AAAs) is a robust treatment. On the other hand, endovascular aneurysm repair (EVAR) has been widespread because of its less invasiveness. However, patients after EVAR frequently require postoperative radiographic examinations and may feel anxiety for their endoleaks. We prospectively evaluated Health-related Quality of Life of the patients with these two fashions using the 8-item Short Form (SF-8). From 2011 to 2013, 89 consecutive elective cases of AAAs were treated. They were prospectively divided into EVAR and open repair groups but not randomly. The exclusion criteria were as follows: perioperative status for other surgeries, infectious aneurysm, severely deteriorated conditions, and patients who cannot answer for these questionnaire or show their consent. The SF-8 questionnaire was completed through interviews preoperatively, and at 1, 3, 6, and 12 months after treatment. The SF-8 questionnaire was completed for 55 cases [EVAR group (ER): 25, open repair group (OR): 30]. There was no significant difference between these groups regarding patients' characteristics except congestive heart disease. The preoperative scores of the SF-8 were similar in both groups except physical function and social function, which were lower in ER (p < 0.05). There was no operative death in both groups. Operative duration and hospital stay in EVAR were significantly shorter than those in OR (p < 0.05). Follow-up rate at 1, 3, 6, and 12 months was 100, 100, 68.0, and 64.0% in ER, and 100, 90.0, 80.0, and 66.6% in OR, respectively. During follow-up, both groups had no AAAs associated death. Regarding changes of the SF-8 scales, there were some trends at physical component summary score (PCS) and mental component summary score (MCS) in ER. The PCS decreased at 1 month, gradually increased at 3 months, and levelled off until 12 months. The MCS increased at 1 and 3 months, but gradually went down and almost stayed at the same level as preoperative one at 12 months. In OR, PCS and MCS decreased at 1 month and after that increased gradually at 3 and 6 months, and stayed the same at 12 months. The MCS recovered to preoperative score earlier than the PCS. In this study, EVAR did not show any significant mental disturbance based on the SF-8 for 1-year comparing to open repair.

Noncoding Subgenomic Flavivirus RNA: Multiple Functions in West Nile Virus Pathogenesis and Modulation of Host Responses

Flaviviruses are a large group of positive strand RNA viruses transmitted by arthropods that include many human pathogens such as West Nile virus (WNV), Japanese encephalitis virus (JEV), yellow fever virus, dengue virus, and tick-borne encephalitis virus. All members in this genus tested so far are shown to produce a unique subgenomic flavivirus RNA (sfRNA) derived from the 3' untranslated region (UTR). sfRNA is a product of incomplete degradation of genomic RNA by the cell 5'–3' exoribonuclease XRN1 which stalls at highly ordered secondary RNA structures at the beginning of the 3'UTR. Generation of sfRNA results in inhibition of XRN1 activity leading to an increase in stability of many cellular mRNAs. Mutant WNV deficient in sfRNA generation was highly attenuated displaying a marked decrease in cytopathicity in cells and pathogenicity in mice. sfRNA has also been shown to inhibit the antiviral activity of IFN-α/β by yet unknown mechanism and of the RNAi pathway by likely serving as a decoy substrate for Dicer. Thus, sfRNA is involved in modulating multiple cellular pathways to facilitate viral pathogenicity; however the overlying mechanism linking all these multiple functions of sfRNA remains to be elucidated.

The goal of this study was to determine the influence of chronic obstructive pulmonary disease (COPD) on health-related quality of life (HRQL) independent of comorbidity. Patients with COPD in general practice, >/=40 years, were selected. To recruit controls, a random sample of persons without COPD and >/=40 years, was taken. HRQL was assessed with the SF-36 and comorbidity was determined by questionnaire. The influence of COPD on HRQL independent of comorbidity (represented by adjusted regression coefficients) was significant for physical functioning (-27.6), role functioning due to physical problems (-21.6), vitality (-14.4), and general health (-25.7), and was minor and not significant for social functioning (-5.6), mental health (-1.3), role functioning due to emotional problems (-2.7), and bodily pain (-2.5). Comorbidity contributed significantly to the HRQL of all domains (-7.6 to -27.1). COPD patients can be impaired in all domains of HRQL. However, impairments in physical functioning, vitality, and general health are related to COPD and to some extent to comorbidity, while impairments in social and emotional functioning do not seem to be related to COPD, but only to comorbidity.

Childhood trauma has long-term adverse effects on physical and psychological health. Previous studies demonstrated that suicide and mental disorders were related to childhood trauma. In China, there is insufficient research available on childhood trauma in patients with mental disorders. Outpatients were recruited from a psychiatric hospital in southern China, and controls were recruited from local communities. The demographic questionnaire, the Childhood Trauma Questionnaire-Short Form (CTQ-SF), and the Social Support Rating Scale (SSRS) were completed by all participants, and the Self-rating Idea of Suicide Scale (SIOSS) were completed only by patients. Prevalence rates of childhood trauma were calculated. Kruskal-Wallis test and Dunnett test were used to compare CTQ-SF and SSRS scores between groups. Logistic regression was used to control demographic characteristics and examine relationships between diagnosis and CTQ-SF and SSRS scores. Spearman's rank correlation test was conducted to analyze relationships between suicidal ideation and childhood trauma and suicidal ideation and social support. The final sample comprised 229 patients with depression, 102 patients with bipolar, 216 patient with schizophrenia, and 132 healthy controls. In our sample, 55.5% of the patients with depression, 61.8% of the patients with bipolar disorder, 47.2% of the patients with schizophrenia, and 20.5% of the healthy people reported at least one type of trauma. In patient groups, physical neglect (PN) and emotional neglect (EN) were most reported, and sexual abuse (SA) and physical abuse (PA) were least reported. CTQ-SF and SSRS total scores, and most of their subscale scores in patient groups were significantly different from the control group. After controlling demographic characteristics, mental disorders were associated with higher CTQ-SF scores and lower SSRS scores. CTQ-SF scores and number of trauma types were positively correlated with the SIOSS score. Negative correlations existed between SSRS scores and the SIOSS score. Our sample may not be sufficiently representative. Some results might have been interfered by demographic characteristics. The SIOSS was not completed by controls. Data from self-report scales were not sufficiently objective. In southern China, childhood trauma is more severe and more prevalent in patients with mental disorders (depression, bipolar disorder and schizophrenia) than healthy people. Among patients with mental disorders in southern China, suicidal ideation is associated with childhood trauma and poor social support. Copyright © 2017 Elsevier B.V. All rights reserved.

The aim of the study was to determine the impact of etonogestrel (ENG)-implant used for contraceptive purpose on Quality of life (QoL) and on sexual function (FSF) of healthy Italian women. The Female Sexual Function Index (FSFI) questionnaire and the Short Form-36 (SF-36) validated questionnaire were administered at baseline, 3 and 6 months after insertion of Nexplanon. The implant seems to have a positive impact on QoL after the first three months of therapy. Users showed an improved general health status and physical role status. The implant did not show negative effects on libido and on sexual function. In the first three months of treatment, users experienced a temporary reduction of vitality, mental health, social functioning and emotional role functioning, which seem to disappear after six months of therapy.

The suicide risk among young adults is related to multiple factors; therefore, it is difficult to predict and prevent suicidal behavior. We conducted the present study to reveal the most important factors relating to suicidal ideation in Japanese university students with major depressive episodes (MDEs) of major depressive disorder (MDD). The subjects were 30 Japanese university students who had MDEs of MDD, and were aged between 18 and 26 years old. They were divided into two groups - without suicide risk group (n=15), and with suicide risk group (n=15) - based on the results of the Mini-International Neuropsychiatric Interview. Additionally, healthy controls were recruited from the same population (n=15). All subjects completed the self-assessment scales including the Beck Depression Inventory 2nd edition (BDI-II), the Beck Hopelessness Scale (BHS), Rosenberg's Self-Esteem Scale (RSES), and SF-36v2™ (The Medical Outcomes Study 36-item short-form health survey version 2), and they were all administered a battery of neuropsychological tests. The RSES score of the suicide risk group was significantly lower than the RSES score of the without suicide risk group, whereas the BDI-II score and the BHS score were not significantly different between the two groups. The mean social functioning score on the SF-36v2 of the with suicide risk group was significantly lower than that of the without suicide risk group. The individual's self-esteem and social functioning may play an important role in suicide risk among young adults with MDEs of MDD.

Transplantation in Japan still depends on living donors even after the new revised law. We must pay attention to protect living donors. Perioperative qualities of life after living donation for liver transplantation were assessed with questionnaires including the Medical Outcomes Study 36-Item Short-Form Health Survey version 2 (SF36-v2). Nonparametric Mann-Whitney tests were used to determine statistical significance. P values<.05 were considered significant. Thirty-one among 33 donors answered questionnaires (93.9%). The 15 men and 16 women of average age of 39.7 years had a median hospital stay of 16 days and median duration after surgery of 78 months. Ten of 33 (35.7%) donors considered themselves to be the only possibility. The decision to a donor was established prior to informed consent in 23 donors (74.1%). Six months were required for them to experience a full recovery after donor surgery. Hamilton depression/anxiety score was significantly increased among donors who considered themselves to be the only possibility or those who had decided prior to informed consent. SF36-v2 revealed a significant decrease in social functioning among donors who did not have sufficient time to decide before surgery. General health was significantly decreased among donors who required more than 6 months for full recovery. Perioperative management of pain influenced general health, physical role, bodily pain, and physical functioning. We must pay attention to depression and anxiety among living donors. More care should be focused on pain control and sharing of information of postoperative courses. Copyright © 2012 Elsevier Inc. All rights reserved.

Objective Although clinical studies have documented that specific anxiety disorders are associated with impaired psychosocial functioning, little is known regarding their comparative effects on health-related quality of life within a general population. The current analysis compares health-related quality of life in a U.S. community-dwelling sample of adults with DSM-IV social anxiety disorder (SAD), generalized anxiety disorders (GAD), panic disorder (PD), and specific phobia (SP). Method Face-to-face survey of a U.S. nationally representative sample of over 43,000 adults aged 18 years and older residing in households and group quarters. Prevalence of DSM-IV anxiety disorders and relative associations with health-related quality of life indicators were examined. Results Roughly 9.8% of respondents met diagnostic criteria for at least one 12-month DSM-IV anxiety disorder which, relative to the non-anxiety-disordered general population, were each associated with lower personal income, increased rates of 12-month physical conditions, and greater numbers of Axis I and Axis II DSM-IV psychiatric conditions. After adjusting for socio-demographic and clinical correlates including other anxiety disorders, GAD was associated with significant decrements in the SF-12 Mental Component Summary score. In similar models, GAD and to a lesser extent PD were significantly associated with impairment in social functioning, role emotional, and mental health SF subscales. Conclusion GAD, followed by PD, appears to exact significant and independent tolls on health-related quality of life. Results underscore the importance of prompt and accurate clinical identification and improving access to effective interventions for these disorders. PMID:20816036

The aim of this study was to investigate whether social structure is associated with cancer pain and quality of life using the Social Structure and Personality Research Framework. This study was a secondary analysis of data from 480 cancer patients. The measurements included socioeconomic variables, self-reported cancer pain using the McGill Pain Questionnaire-Short Form (MPQ-SF), and quality of life measured using the Functional Assessment of Cancer Therapy Scale (FACT-G). The data were analyzed using moderated multiple regression. Cancer pain and quality of life differed significantly with income. The associations between income and pain and quality of life were significant only for the high education group (≥ partial college), and these associations were greater for Caucasians than for their counterparts ( p < .05). When developing interventions, nurses should consider the influence of socioeconomic variables on pain and quality of life while considering possible moderating factors such as education.

Urinary and sexual outcomes in long-term (5+ years) prostate cancer disease free survivors after radical prostatectomy

2009-01-01

Background After long term disease free follow up (FUp) patients reconsider quality of life (QOL) outcomes. Aim of this study is assess QoL in prostate cancer patients who are disease-free at least 5 years after radical prostatectomy (RP). Methods 367 patients treated with RP for clinically localized pCa, without biochemical failure (PSA ≤ 0.2 ng/mL) at the follow up ≥ 5 years were recruited. Urinary (UF) and Sexual Function (SF), Urinary (UB) and Sexual Bother (SB) were assessed by using UCLA-PCI questionnaire. UF, UB, SF and SB were analyzed according to: treatment timing (age at time of RP, FUp duration, age at time of FUp), tumor characteristics (preoperative PSA, TNM stage, pathological Gleason score), nerve sparing (NS) procedure, and hormonal treatment (HT). We calculated the differences between 93 NS-RP without HT (group A) and 274 non-NS-RP or NS-RP with HT (group B). We evaluated the correlation between function and bother in group A according to follow-up duration. Results Time since prostatectomy had a negative effect on SF and a positive effect SB (both p < 0.001). Elderly men at follow up experienced worse UF and SF (p = 0.02 and p < 0.001) and better SB (p < 0.001). Higher stage PCa negatively affected UB, SF, and SB (all: p ≤ 0.05). NS was associated with better UB, SF and SB (all: p ≤ 0.05); conversely, HT was associated with worse UF, SF and SB (all: p ≤ 0.05). More than 8 years after prostatectomy SF of group A and B were similar. Group A subjects (NS-RP without HT) demonstrated worsening SF, but improved SB, suggesting dissociation of the correlation between SF and SB over time. Conclusion Older age at follow up and higher pathological stage were associated with worse QoL outcomes after RP. The direct correlation between UF and age at follow up, with no correlation between UF and age at time of RP suggests that other issues (i.e: vascular or neurogenic disorders), subsequent to RP, are determinant on urinary incontinence. After NS-RP without HT the correlation between SF and SB is maintained for 7 years, after which function and bother appear to have divergent trajectories. PMID:19912640

Benign paroxysmal positional vertigo (BPPV) is a common cause of dizziness within the geriatric population causing disability. The diagnosis is established by the position-induced rotatory nystagmus, related to the involved ear, demonstrated by the Dix-Hallpike test (DHT). Although the Epley's modified manoeuvre, or particle respositioning manoeuvre (PRM), is an effective treatment for this disorder, its impact on health outcome in patients over 60 years old is unknown. To assess BPPV health-related quality of life in elderly individuals using the Medical Outcomes Study 36-Item Short Form Health Survey (SF-36) and the Dizziness Handicap Inventory Short Form (DHI-S). A prospective study including new cases of BPPV in patients older than 60 years was carried out. The diagnosis was based on the history of recurrent sudden crises of vertigo and a typical positional-induced nystagmus during the DHT. All patients were treated by a single PRM and relapses were investigated a the 30th post-treatment day. DHT was found negative in 82% (23/28) individuals at 30 days. The eight scales of the SF-36 have a good internal consistency reliability in patients with BPPV (Cronbach's alpha > 0.7). The average standardized score for each SF-36 scale was compared with the reference population normative data, showing differences with norms for role physical, body pain, social function, role emotional and mental health. After PRM, patients restored scores to norms, showing a significant increase in role physical (p < 0.05), body pain (p < 0.04), vitality (p < 0.02), social function (p < 0.003) and mental health scores (p < 0.005). DHI-S total score significantly decreased from 17.19 +/- 9.06 (mean +/- SD) at the first day to 9.70 +/- 10.13 at 30 days (p < 0.001). BPPV has a significant impact on health-related quality of life in elderly patients on their emotional and physical states compared to those unaffected. The PRM can restore health-related quality of life in elderly patients with BPPV. Copyright 2004 S. Karger AG, Basel

To examine the relation of age with symptom severity and quality of life (QOL) in patients with fibromyalgia, and to compare physical and mental health of our female patients with those of the US female general population. We studied 978 patients with fibromyalgia from May 1, 2001 through April 30, 2004, and divided them into age groups of young (≤39 years), middle-aged (40-59 years), and older (≥60 years). They completed the Fibromyalgia Impact Questionnaire and the Short Form-36 Health Status Questionnaire (SF-36). Standardized SF-36 physical and mental health summary scores were compared with those of the US female general population of similar age. One-way analysis of variance and post hoc paired t test analyses were performed to detect differences across age groups. Pairwise comparison found young and middle-aged patients having worse fibromyalgia symptoms in all subscales except the anxiety subscale compared with older patients (P≤.01). Similarly, these young and middle-aged patients had worse QOL in the SF-36 mental component summary, as well as SF-36 general health perceptions, vitality, social functioning, and mental health index, compared with older patients (all P<.001). When the QOL of our female patients was compared with that of the US female general population of similar age with standardized SF-36 scores, all age groups had lower QOL in physical, as well as mental, health, with more reduction in physical health, particularly in young patients. Our study shows that symptom severity and QOL differ across age groups in patients with fibromyalgia, with young and middle-aged patients having poorer QOL and worse fibromyalgia symptoms than do older patients. QOL in physical health was reduced more than in mental health, particularly in young patients, compared with the general population.

Military personnel deployed abroad could be exposed to more risk factors that adversely affect quality of life. In this study, we examined psychiatric symptoms and quality of life in Turkish Armed Forces deployed to Afghanistan. A total of 289 Turkish military personnel working in Afghanistan enrolled in this study. They completed two surveys containing questions about socio-demographic characteristics. Data were collected and analyzed from 258 of the participants. The general symptom scores (GSI) were above 1 in 20.8 Percent (n=54) of the participants. The lowest SF-36 scores by the sub-groups were mental health (59.14 ± 18.56) and vitality (59.25 ± 21.17). The highest score was in the physical function subscale (84.42 ± 19.53). All Quality of Life Questionnaire Short Form (SF-36)subscale scores were lower in the GSI above 1 group than the GSI below 1 group. In the GSI above 1 group: education level and depression affected SF-36 physical functioning; paranoid ideation and somatization affected SF-36 role limitations due to physical health; age and somatization affected SF-36 pain; age affected SF-36 general health; phobic anxiety affected SF-36 vitality; age, tenure of occupation, tenure abroad; and phobic anxiety affected SF-36 mental health. The negative effects of psychiatric symptoms on the quality of life were similar to those in the general population and in specific disease groups. These results should be considered when evaluating the mental health of military personnel deployed abroad.

In these last years, there has been an increasing use of the Structure from Motion (SfM) techniques applied to Cultural Heritage. The accessibility of SfM software can be especially advantageous to users in non-technical fields or to those with limited resources. Thanks to SfM using, everyone can make with a digital camera a 3D model applied to an object of both Cultural Heritage, and physically Environment, and work arts, etc. One very interesting and useful application can be envisioned into museum collection digitalization. In the last years, a social experiment has been conducted involving young generation to live a social museum using their own camera to take pictures and videos. Students of university of Catania and Palermo were involved into a national event #digitalinvasion (2015-2016 editions) offering their personal contribution: they realized 3D models of the museums collection through the SfM techniques. In particular at the National Archaeological Museum Salinas in Palermo, it has been conducted an organized survey to recognize the most important part of the archaeological collection. It was a success: in both #digitalinvasion National Event 2015 and 2016 the young students of Engineering classes carried out, with Photoscan Agisoft, more than one hundred 3D models some of which realized by phone camera and some other by reflex camera and some other with compact camera too. The director of the museum has been very impressed from these results and now we are going to collaborate at a National project to use the young generation crowdsourcing to realize a semi-automated monitoring system at Salinas Archaeological Museum.

Silk fibroin (SF) is a natural polymer widely used and studied for diverse applications in the biomedical field. Recently, genetically modified silks, particularly fluorescent SF fibers, were reported to have been produced from transgenic silkworms. However, they are currently limited to textile manufacturing. To expand the use of transgenic silkworms for biomedical applications, a solution form of fluorescent SF needed to be developed. Here, we describe a novel method of preparing a fluorescent SF solution and demonstrate long-term fluorescent function up to one year after subcutaneous insertion. We also show that fluorescent SF labeled p53 antibodies clearly identify HeLa cells, indicating the applicability of fluorescent SF to cancer detection and bio-imaging. Furthermore, we demonstrate the intraoperative use of fluorescent SF in an animal model to detect a small esophageal perforation (0.5 mm). This study suggests how fluorescent SF biomaterials can be applied in biotechnology and clinical medicine. Copyright © 2015 Elsevier Ltd. All rights reserved.

Health related quality of life (HRQOL) over course of the disease was ascertained in SLE patients from LUMINA, a multiethnic US cohort, using the SF-36-derived utility measure, the SF-6D. All available visits were examined to predict HRQOL using either variables from the baseline or enrollment visits or from the preceding visits. The physical and mental component summary (PCS and MCS, respectively) measures of the SF-36 were also examined. A total of 2662 visits from 588 SLE patients were included; 90% of the patients were women, 19% Hispanic-Texans, 17% Hispanic-Puerto Ricans, 35% African Americans and 29% Caucasians. The patients' mean (SD) SF-6D was 0.6 (0.1). In multivariable analyses, Hispanic-Texan ethnicity and higher levels of social support were predictors of HRQOL whereas older age, poverty, greater disease activity and damage and higher levels of fatigue, helplessness and abnormal illness-related behaviors were negative predictors. Prior SF-6D was the strongest variable predictive of subsequent HRQOL, when included. The analyses in which the PCS and MCS were examined as end-points were, overall, consistent with the SF-6D results. We conclude that the SF-6D index provides an adequate measure of self-perceived HRQOL and that patients' self-perception of HRQOL is influenced by disease and non-disease related factors.

A new sulfone derivatized acceptor (n-type) polyphenylenevinylene "SF-PPV" with nano meter sizes and functional terminals has been synthesized and characterized. The SF-PPV-I that contains hydrocarbon alkyl-sulfone moieties has a strong photoluminescence in both solution and in solid thin film states. In dichloromethane, the 5-10 nm sized SF-PPV has a maximum emission at about 530 nm with excitation maximum at about 490 nm. UV-VIS shows a absorption peak onsite at about 500 nm. Optical spectroscopy and electrochemical studies revealed that the SF-PPV-I has an LUMO level at about -3.6 eV (relative to vacuum), and an HOMO level at about -6.1 eV. The average size (length) of SF-PPV-I can be controlled on the nano meter scale via synthetic means. The SF-PPV has the potential in developing polymer based supramolecular opto-electronic semiconductor devices.

To assess the responsiveness of one generic questionnaire, Medical Outcomes Study Short Form-36 (SF-36), and one region-specific outcome measure, Lower Extremity Functional Scale (LEFS), in patients with traumatic injuries of lower extremities. A prospective and observational study of patients after traumatic injuries of lower extremities. Assessments were performed at baseline and 3 months later. In-patients and out-patients in two university hospitals in Taiwan. A convenience sample of 109 subjects were evaluated and 94 (86%) were followed. Not applicable. Assessments of responsiveness with distribution-based approach (effect size, standardized response mean [SRM], minimal detectable change) and anchor-based approach (receiver's operating curve analysis, ROC analysis). LEFS and physical component score (PCS) of SF-36 were all responsive to global improvement, with fair-to-good accuracy in discriminating between participants with and without improvement. The area under curve gained by ROC analysis for LEFS and SF-36 PCS was similar (0.65 vs. 0.70, p=0.26). Our findings revealed comparable responsiveness of LEFS and PCS of SF-36 in a sample of subjects with traumatic injuries of lower limbs. Either type of functional measure would be suitable for use in clinical trials where improvement in function was an endpoint of interest. Copyright © 2014 Elsevier Ltd. All rights reserved.

Yoga classes designed for women with premenstrual syndrome are available, but their efficacy is unclear. We investigated the effects of 12 weeks’ yoga exercise (yoga intervention) on premenstrual symptoms in menstruating females in Taiwan. Sixty-four subjects completed the yoga intervention, and before and after the intervention filled out a structured self-report questionnaire about their demographics, personal lifestyle, menstrual status, baseline menstrual pain scores, premenstrual symptoms, and health-related quality of life. Of 64 subjects, 90.6% reported experiencing menstrual pain during menstruation. After the yoga intervention, subjects reported decreased use of analgesics during menstruation (p = 0.0290) and decreased moderate or severe effects of menstrual pain on work (p = 0.0011). The yoga exercise intervention was associated with the improvement of the scale of physical function (p = 0.0340) and bodily pain (p = 0.0087) of the SF-36, and significantly decreased abdominal swelling (p = 0.0011), breast tenderness (p = 0.0348), abdominal cramps (p = 0.0016), and cold sweats (p = 0.0143). Menstrual pain mitigation after yoga exercise correlated with improvement in six scales of the SF-36 (physical function, bodily pain, general health perception, vitality/energy, social function, mental health). Employers can educate female employees about the benefits of regular exercise such as yoga, which may decrease premenstrual distress and improve female employee health. PMID:27438845

Catquest questionnaire was originally developed in Swedish to measure patients' self-assessed visual function to evaluate the benefit of cataract surgery. The result of the Rasch analysis leading to the creation of the nine-item short form of Catquest, (Catquest-9SF), and it had been translated and validated in English. The aim is therefore to evaluate the translated Catquest-9SF questionnaire in Malay and Chinese (Mandarin) language version for measuring patient-reported visual function among cataract population in Malaysia. The English version of Catquest-9SF questionnaire was translated and back translated into Malay and Chinese languages. The Malay and Chinese translated versions were self-administered by 236 and 202 pre-operative patients drawn from a cataract surgery waiting list, respectively. The translated Catquest-9SF data and its four response options were assessed for fit to the Rasch model. The Catquest-9SF performed well in the Malay and Chinese translated versions fulfilling all criteria for valid measurement, as demonstrated by Rasch analysis. Both versions of questionnaire had ordered response thresholds, with a good person separation (Malay 2.84; and Chinese 2.59) and patient separation reliability (Malay 0.89; Chinese 0.87). Targeting was 0.30 and -0.11 logits in Malay and Chinese versions respectively, indicating that the item difficulty was well suited to the visual abilities of the patients. All items fit a single overall construct (Malay infit range 0.85-1.26, outfit range 0.73-1.13; Chinese infit range 0.80-1.51, outfit range 0.71-1.36), unidimensional by principal components analysis, and was free of Differential Item Functioning (DIF). These results support the good overall functioning of the Catquest-9SF in patients with cataract. The translated questionnaire to Malay and Chinese-language versions are reliable and valid in measuring visual disability outcomes in the Malaysian cataract population.

There is a dearth of literature dealing with the impact of the severity of posttraumatic symptoms and of comorbid mental disorders on the health-related quality of life (HRQOL) of victims of civilian violence with a primary diagnosis of PTSD. To investigate the influence of the severity of posttraumatic symptoms and of presence of comorbid mental disorders on the HRQOL of treatment-seeking outpatients with PTSD. A sample of 65 PTSD patients was recruited in a specialized outpatient clinic. The volunteers had the diagnoses of PTSD and of comorbid mental disorders established with the Structured Clinical Interview for DSM-IV Axis I Disorders (SCID-I). The severity of posttraumatic, depression and anxiety symptoms was measured with the PCL-C, BDI and BAI, respectively. HRQOL was assessed by means of the SF-36, a 36-item self-administered scale that measures eight domains of quality of life: vitality, physical functioning, bodily pain, general health perceptions, physical role functioning, emotional role functioning, social role functioning, and mental health. Multiple linear regression models were fitted to investigate the relationship between the severity of posttraumatic, mood, and anxiety symptoms; the presence of specific current comorbid disorders and of psychotic symptoms, and the number of current comorbid conditions for each of the eight domains of HRQOL, after adjusting for the effect of sociodemographic characteristics. The severity of PTSD symptoms predicted worse HRQOL in all eight domains of SF-36, even after controlling for the severity of depression and anxiety symptoms, the presence of panic disorder, OCD, specific and social phobia, psychotic symptoms, and the number of comorbid disorders. The strongest negative association between PTSD symptoms severity and HRQOL was found in the Social Functioning domain. Although the inclusion of the depressive symptoms in the models led to a reduction of the magnitude of the negative association between the severity of PTSD symptoms and the HRQOL domain scores, the former still accounted for most of the explained variance of the latter. We found that even in the presence of comorbid mental disorders, the severity of posttraumatic symptoms remained the strongest predictor for impaired HRQOL in PTSD outpatients. Our results suggest that improvement of HRQOL should be considered a therapeutic objective and an essential outcome measure in the treatment of PTSD. Copyright © 2015 Elsevier Inc.

The still-face paradigm (SFP) was designed to assess infant expectations that parents will respond to infant communicative signals. During the still-face (SF) episode, the parent ceases interaction and maintains a neutral expression. Original, qualitative descriptions of infant behavior suggested changes within the SF episode: infants decrease bidding and disengage from their impassive parent. Research has documented changes in mean levels of infant behavior between episodes of the SFP. The hypothesis that infant behavior changes within the SF episode has not been empirically tested. In this study, hierarchical linear modeling indicated that infant gazing at the parent, smiling, and social bidding (smiling while gazing at the parent) decreased with time in the SF episode, while infant cry-face expressions increased. Changes in infant behaviors within the SF episode were associated with infant attachment and infant internalizing problems. The dynamic still-face effect quantifies infant initiation of interaction in the face of parental unresponsiveness and is a potential predictor of individual differences in development.

Receptor tyrosine kinases (RTKs) have been the subject of intense investigation due to their widespread deregulation in cancer and the prospect of developing targeted therapeutics against these proteins. The Ron RTK has been implicated in tumor aggressiveness and is a developing target for therapy, but its function in tumor progression and metastasis is not fully understood. We examined Ron activity in human breast cancers and found striking predominance of an activated Ron isoform known as short-form Ron (sfRon), whose function in breast tumors has not been explored. We found that sfRon plays a significant role in aggressiveness of breast cancer in vitro and in vivo. sfRon expression was sufficient to convert slow-growing, nonmetastatic tumors into rapidly growing tumors that spontaneously metastasized to liver and bones. Mechanistic studies revealed that sfRon promotes epithelial-mesenchymal transition, invasion, tumor growth, and metastasis through interaction with p85, the regulatory subunit of phosphoinositide 3-kinase (PI3K). Inhibition of PI3K activity, or introduction of a single mutation in the p85 docking site on sfRon, completely eliminated the ability of sfRon to promote tumor growth, invasion, and metastasis. These findings reveal sfRon as an important new player in breast cancer and validate Ron and PI3K as therapeutic targets in this disease. PMID:22207901

Elucidation of the spaceflight (SF) effects on the adult stem and progenitor cells is an important goal in space biology and medicine. A unique opportunity for this was provided by project "BION-M1". The purpose of this study was to evaluate the effects of 30-day SF on biosatellite, 7-day recovery (SFR), and subsequent ground control (GC) experiment on the mononuclear cells (MNCs) from C57/BI/6N murine tibia bone marrow. Also, hematopoietic and stromal precursor functions were characterized ex vivo. There was no significant difference in the total MNC number between experimental groups. After SF, immunophenotyping revealed an increase of large-sized CD45 + MNCs corresponded to committed hematopoietic progenitors. The total hematopoietic colony-forming unit (CFU) number decreased after SF and did not restore after 7 day of recovery due to predominant reduction of bi- and multipotent CFUs and primitive burst-forming units in favor of unipotent CFUs. Functional activity of stromal precursors in vitro was only slightly altered. SF cells displayed the enhanced expression of alkaline phosphatase. The data of the GC experiment demonstrated the preservation of the functional activity of progenitor cells from mice bone marrow. The activation of erythropoiesis in expense of burst-forming units of erythrocytes elevation was detected. After 7 days of recovery, the number of colony-forming units of fibroblast (CFUs-f) was similar to the vivarium control, while the proliferative activity of bone marrow stromal precursors decreased. The present study demonstrated that certain hematopoietic progenitors are susceptible to SF factors, while the stromal precursors displayed a certain degree of resistance. These data indicate mild and reversible alterations of bone marrow progenitors after SF.

Catquest-9SF is a 9-item visual disability questionnaire developed for evaluating patient-reported outcome measures after cataract surgery. The aim of this study was to use Rasch analysis to determine the responsiveness of Catquest-9SF for corneal transplant patients. Patients who underwent corneal transplantation primarily to improve vision were included. One group (n = 199) completed the Catquest-9SF questionnaire before corneal transplantation and a second independent group (n = 199) completed the questionnaire 2 years after surgery. All patients were recorded in the Swedish Cornea Registry, which provided clinical and demographic data for the study. Winsteps software v.3.91.0 (Winsteps.com, Beaverton, OR) was used to assess the fit of the Catquest-9SF data to the Rasch model. Rasch analysis showed that Catquest-9SF applied to corneal transplant patients was unidimensional (infit range, 0.73-1.32; outfit range, 0.81-1.35), and therefore, measured a single underlying construct (visual disability). The Rasch model explained 68.5% of raw variance. The response categories of the 9-item questionnaire were ordered, and the category thresholds were well defined. Item difficulty matched the level of patients' ability (0.36 logit difference between the means). Precision in terms of person separation (3.09) and person reliability (0.91) was good. Differential item functioning was notable for only 1 item (satisfaction with vision), which had a differential item functioning contrast of 1.08 logit. Rasch analysis showed that Catquest-9SF is a valid instrument for measuring visual disability in patients who have undergone corneal transplantation primarily to improve vision.

We have recently developed a methodology for the calculation of exchange coupling constants J in weakly interacting polynuclear metal clusters. The method is based on unrestricted and restricted second order spin-flip constricted variational density functional theory (SF-CV(2)-DFT) and is here applied to eight binuclear copper systems. Comparison of the SF-CV(2)-DFT results with experiment and with results obtained from other DFT and wave function based methods has been made. Restricted SF-CV(2)-DFT with the BH&HLYP functional yields consistently J values in excellent agreement with experiment. The results acquired from this scheme are comparable in quality to those obtained by accurate multi-reference wave function methodologies such as difference dedicated configuration interaction and the complete active space with second-order perturbation theory. © 2011 American Institute of Physics

Can Preoperative Patient-reported Outcome Measures Be Used to Predict Meaningful Improvement in Function After TKA?

Despite the overall effectiveness of total knee arthroplasty (TKA), a subset of patients do not experience expected improvements in pain, physical function, and quality of life as documented by patient-reported outcome measures (PROMs), which assess a patient's physical and emotional health and pain. It is therefore important to develop preoperative tools capable of identifying patients unlikely to improve by a clinically important margin after surgery. The purpose of this study was to determine if an association exists between preoperative PROM scores and patients' likelihood of experiencing a clinically meaningful change in function 1 year after TKA. A retrospective study design was used to evaluate preoperative and 1-year postoperative Knee injury and Osteoarthritis Outcome Score (KOOS) and SF-12 version 2 (SF12v2) scores from 562 patients who underwent primary unilateral TKA. This cohort represented 75% of the 750 patients who underwent surgery during that time period; a total of 188 others (25%) either did not complete PROM scores at the designated times or were lost to follow-up. Minimum clinically important differences (MCIDs) were calculated for each PROM using a distribution-based method and were used to define meaningful clinical improvement. MCID values for KOOS and SF12v2 physical component summary (PCS) scores were calculated to be 10 and 5, respectively. A receiver operating characteristic analysis was used to determine threshold values for preoperative KOOS and SF12v2 PCS scores and their respective predictive abilities. Threshold values defined the point after which the likelihood of clinically meaningful improvement began to diminish. Multivariate regression was used to control for the effect of preoperative mental and emotional health, patient attributes quantified by SF12v2 mental component summary (MCS) scores, on patients' likelihood of experiencing meaningful improvement in function after surgery. Threshold values for preoperative KOOS and SF12v2 PCS scores were a maximum of 58 (area under the curve [AUC], 0.76; p < 0.001) and 34 (AUC, 0.65; p < 0.001), respectively. Patients scoring above these thresholds, indicating better preoperative function, were less likely to experience a clinically meaningful improvement in function after TKA. When accounting for mental and emotional health with a multivariate analysis, the predictive ability of both KOOS and SF12v2 PCS threshold values improved (AUCs increased to 0.80 and 0.71, respectively). Better preoperative mental and emotional health, as reflected by a higher MCS score, resulted in higher threshold values for KOOS and SF12v2 PCS. We identified preoperative PROM threshold values that are associated with clinically meaningful improvements in functional outcome after TKA. Patients with preoperative KOOS or SF12v2 PCS scores above the defined threshold values have a diminishing probability of experiencing clinically meaningful improvement after TKA. Patients with worse baseline mental and emotional health (as defined by SF12v2 MCS score) have a lower probability of experiencing clinically important levels of functional improvement after surgery. The results of this study are directly applicable to patient-centered informed decision-making tools and may be used to facilitate discussions with patients regarding the expected benefit after TKA.

Despite effective treatment for recent hepatitis C (HCV) infection, side-effects and adherence concerns limit its use among people who inject drugs (PWID). This study evaluated health-related quality of life (HRQoL) and social functioning following infection and during recent HCV treatment. The Australian Trial of Acute Hepatitis C studied the natural history and treatment of recent HCV infection. HRQoL (SF-12v2) and social functioning (Opiate Treatment Index score) were measured over 48 weeks and their impact on treatment uptake, adherence and virological response were assessed. Of 163 participants, 111 received treatment (HCV n = 74, SVR 55%; HCV/HIV n = 37, SVR 74%). 116 (71%) were male, 124 (76%) ever injected drugs, with 55 (36%) injecting recently and 28/55 (51%) reported needle/syringe sharing. At baseline, median physical and mental HRQoL was 54 units (IQR 46-58) and 46 (35-54) (reference median: 50), respectively, and median social functioning score was 11 units (7-17). Higher social function (<10 vs ≥15) predicted increased treatment uptake (AOR 3.43, 95%CI 1.01-11.6, p = 0.048) and higher SVR (AOR 5.11, 95%CI 1.30-20.15, p = 0.020). After adjustment, treated participants had lower physical (-4.90 units, 95%CI -6.33 to -3.48, p<0.001) and mental HRQoL (-3.7 units, 95%CI -5.55 to -1.86, p<0.001) at on-treatment visits, but HRQoL returned to baseline levels during follow-up. Social functioning can predict recent HCV treatment uptake and SVR. Efforts to maximise social stability may improve treatment response. Pegylated-interferon treatment is associated with reduced HRQoL on-treatment in an already vulnerable population of PWID that would be better served by interferon-free regimens particularly in treated target at PWID to prevent transmission.

Modifications to Langley 0.3-m TCT adaptive wall software for heavy gas test medium, phase 1 studies

NASA Technical Reports Server (NTRS)

Murthy, A. V.

1992-01-01

The scheme for two-dimensional wall adaptation with sulfur hexafluoride (SF6) as test gas in the NASA Langley Research Center 0.3-m Transonic Cryogenic Tunnel (0.3-m TCT) is presented. A unified version of the wall adaptation software has been developed to function in a dual gas operation mode (nitrogen or SF6). The feature of ideal gas calculations for nitrogen operation is retained. For SF6 operation, real gas properties have been computed using the departure function technique. Installation of the software on the 0.3-m TCT ModComp-A computer and preliminary validation with nitrogen operation were found to be satisfactory. Further validation and improvements to the software will be undertaken when the 0.3-m TCT is ready for operation with SF6 gas.

To compare the psychometric properties of 2 heart failure (HF)-specific quality of life questionnaires and the Medical Outcomes Study 36-Item Short-Form Health Survey (SF-36) in patients with HF. A methodological study based on 3-month follow-up data for evaluating psychometric properties of health-related quality of life (HRQOL) questionnaires. Cardiac rehabilitation center at a cardiovascular research institute. Eligible patients with HF (N=60). Exercise training in cardiac rehabilitation. The SF-36, the MacNew Heart Disease questionnaire, and the Minnesota Living With Heart Failure Questionnaire (MLHFQ) and New York Heart Association functional classification. Items from the MLHFQ and the MacNew questionnaire had acceptable correlations (r>.30, P<.05). Internal consistency and test-retest reliability were adequate at ≥0.7 for the MLHFQ subscales. Correlations for the MLHFQ and the MacNew with SF-36 similar items ranged from .28 to .50 and from .26 to .60, respectively. Similar scales from the MacNew and MLHFQ showed strong correlations at baseline and follow-up, supporting the convergent validity. Improvement in HRQOL was significant for all MLHFQ subscales (P<.001) and the MacNew emotional (P<.05) and social (P<.001) subscales. The MLHFQ demonstrated the most responsiveness to changes and discriminated disease severity the best. The follow-up scores for all MLHFQ and 2 MacNew subscales were significantly greater in patients who improved compared with those who showed no change or deteriorated. The MLHFQ was more responsive to changes of HRQOL than the MacNew questionnaire over time in patients with HF. The MacNew questionnaire was more responsive to changes than the SF-36.

Understanding individual factors associated with return to work (RTW) post-injury is an important goal of compensation systems research. The aim of the present study was to determine factors associated with time to return to work following acute unintentional injuries. A prospective cohort study was conducted in Victoria, Australia. The cohort comprised 133 persons who were employed at the time they were admitted to one of three study hospitals. Baseline health status data was obtained retrospectively at one-week post-injury and participants were further surveyed at 1, 6, 12, 26 and 52 weeks post-injury to measure recovery. Multivariate Cox proportional hazards regression analysis was used to examine the association between potential prognostic factors and time to RTW during the 12 month study. At the end of 12 months follow-up, 81.2% of the study cohort had returned to work. Older age, increased injury severity, self reported symptomatic pain and poor mental health at 1 week post-injury were associated with extended time to RTW. A significant statistical interaction between the receipt of compensation and high social functioning as measured by the SF-36 or strong social relationships as measured by the Assessment of Quality of Life was associated with earlier RTW. Participants reporting strong social relationships and high social functioning at 1 week post-injury and entitled to injury compensation returned to work 2.05 and 3.66 times earlier respectively, than similar participants with no entitlement to compensation. Both injury-related and psychosocial factors were associated with the duration of time to RTW following acute unintentional injuries. This study replicated previously reported findings on social functioning and compensation from an independent acute trauma sample. Programs or policies to improve social functioning early post-injury may provide opportunities to improve the duration of time to RTW following injury.

The performance of daily activities is a major challenge for people with chronic obstructive pulmonary disease (COPD). The Functional Performance Inventory (FPI) was developed based on an analytical framework of functional status and qualitative interviews with COPD patients describing these difficulties. The 65-item FPI was reduced to a 32-item short form (SF) through a systematic process of qualitative and quantitative item reduction and formatted for greater clarity and ease of use. This study examined the content validity of the reduced, reformatted form of the instrument, the FPI-SF. Qualitative cognitive interviews were conducted with COPD patients recruited from three geographically diverse pulmonary clinics in the United States. Interviews were designed to assess respondent interpretation of the instrument, evaluate clarity and ease of completion, and identify any new activities participants found important and difficult to perform that were not represented by the existing items. Twenty subjects comprised the sample; 12 (60%) were male, 14 (70%) were Caucasian, the mean age was 63.0 ± 11.3 years, 12 (60%) were retired, the mean forced expiratory volume in 1 second (FEV(1)) was 1.5 ± 0.5 L, and the mean percent predicted FEV(1) was 48.4% ± 13.1%. Participants understood the FPI-SF as intended, including instructions, items, and response options. Two minor formatting changes were suggested to improve clarity of presentation. Participants found the content of the FPI-SF to be comprehensive, with items covering activities they felt were important and often difficult to perform. These results, together with its development history and previously tested quantitative properties, suggest that the FPI-SF is content valid for use in clinical studies of COPD.

This study investigated whether the Health Assessment Questionnaire (HAQ) can be used as an instrument to assess the need for social support measures that address activity limitations and participation issues in patients with rheumatoid arthritis (RA). This multicenter observational study included patients with RA and disease duration of at least one year, consulting their rheumatologist for routine evaluation of disease activity. In the single study visit data on demographics, disease history and current treatment were collected. DAS28 values were collected to evaluate current RA disease activity. Patients were asked to fill out the HAQ and SF-36 questionnaires. Receiver Operator Characteristics (ROC) curves were constructed to evaluate the performance of the HAQ, SF-36 and DAS28 in predicting the need for nine supporting measures available for chronically ill patients in the Belgian social security system. The expert opinion of the treating rheumatologist was used as a reference. The study included 316 patients with a mean age of 59.8 ± 12.6 years, disease duration of 11.4 ± 9.3 years, mean DAS28 values of 2.83 ± 1.17. Mean HAQ score was 0.95 ± 0.73, mean SF-36 score 56.5 ± 21.3. HAQ scores >1 were observed in 39.4% of patients. The area under the HAQ ROC curve was consistently >0.7 and higher for the HAQ than for SF-36 or DAS28 for all support measures. Rheumatologists on average recommended 3.67 support measures. The HAQ score was found to be a good predictor of the need for social support measures in patients with RA.

The aim of this study was to investigate the effects of the quality of life and psychological condition of female patients with fibromyalgia and their spouses on sexual function. A total of 32 female patients diagnosed with fibromyalgia and their spouses were analyzed. Thirty married couples were included in the study as the control group. The demographic data of the fibromyalgia patients were recorded, a visual analog scale was used to evaluate the level of pain, and the Fibromyalgia Impact Questionnaire was used to evaluate the impact of the symptoms on the quality of life of the patients. The quality of life of both the patients and the control group were evaluated using the Short Form 36 (SF-36), and psychological variables were evaluated using the Beck Depression Inventory (BDI) and Beck Anxiety Inventory. Sexual function was assessed using the Female Sexual Function Index for female participants and the International Index of Erectile Function (IIEF) for male participants. The IIEF erectile dysfunction scores were significantly lower in the spouses of female patients with fibromyalgia than in the control group (p < 0.05), and the BDI scores were significantly higher in the spouses of the female patients with fibromyalgia (p < 0.05). Among the SF-36 scores, the emotional and physical roles were significantly lower in the spouses of the female patients with fibromyalgia (p = 0.003 and p = 0.004, respectively). In all spouses of FMS patients and controls, there was a significantly negative correlation between erectile function, the BDI score, and to be married with FMS patient and positive correlations between erectile function and emotional role, social function, mental health, SF-36 pain score, and general health (p < 0.05 for all). In a linear regression model, BDI, to be married with FMS patient and general health were found to affect erectile function (beta regression coefficient = -0.572, SE = 0.082, p = 0.001; beta regression coefficient = -0.332, SE = 1.619, p = 0.007; beta regression coefficient = 0.445, SE = 0.065, p = 0.005, respectively). Being a spouse of a patient with fibromyalgia might significantly interfere with quality of life and lead to a high rate of sexual dysfunction. Spouses of patients with fibromyalgia might also be investigated for sexual dysfunction and quality of life. Treatment programs for this group should be considered.

To improve the clinical utility of the Moorong Self-Efficacy Scale (MSES) by reexamining its factor structure and comparing its performance against a measure of general self-efficacy in persons with spinal cord injury (SCI). Cross-sectional survey design. Community. Adults with SCI (N=161; 118 men and 43 women) recruited from Australia (n=82) and the United States (n=79), including 86 with paraplegia and 75 with tetraplegia. None. Confirmatory factor analysis deriving fit indices on reported 1-, 2-, and 3-factor structures for the MSES. Exploratory factor analysis of MSES using principal component analysis with promax oblique rotation and structure validation, with correlations and multiple regression using cross-sectional data from the Sherer General Self-Efficacy Scale and Medical Outcomes Study 36-Item Short-Form Health Survey (SF-36). The MSES was confirmed to have a 3-factor structure, explaining 61% of variance. Two of the factors, labeled social function self-efficacy and personal function self-efficacy, were SCI condition-specific, whereas the other factor (accounting for 9.7% of variance) represented general self-efficacy, correlating most strongly with the Sherer General Self-Efficacy Scale. Correlations and multiple regression analyses between MSES factors, Sherer General Self-Efficacy Scale total score, SF-36 Physical and Mental Component Summary scores, and SF-36 domain scores support validity of this MSES factor structure. No significant cross-cultural differences existed between Australia and the United States in total MSES or factor scores. The findings support a 3-factor structure encompassing general and SCI domain-specific self-efficacy beliefs and better position the MSES to assist SCI rehabilitation assessment, planning, and research.

Depression and diminished health status are common in adults with diabetes, but few studies have investigated associations with socio-economic environment. The objective of this manuscript was to evaluate the relationship between neighborhood-level SES and health status and depression. Individual-level data on 1010 participants at baseline in Look AHEAD (Action for Health in Diabetes), a trial of long-term weight loss among adults with type 2 diabetes, were linked to neighborhood-level SES (% living below poverty) from the 2000 US Census (tracts). Dependent variables included depression (Beck Inventory), and health status (Medical Outcomes Study (SF-36) scale). Multi-level regression models were used to account simultaneously for individual-level age, sex, race, education, personal yearly income and neighborhood-level SES. Overall, the % living in poverty in the participants' neighborhoods varied, mean =11% (range 0-67%). Compared to their counterparts in the lowest tertile of neighborhood poverty (least poverty), those in the highest tertile (most poverty) had significantly lower scores on the role-limitations(physical), role limitations(emotional), physical functioning, social functioning, mental health, and vitality sub-scales of the SF-36 scale. When evaluating SF-36 composite scores, those living in neighborhoods with more poverty had significantly lower scores on the physical health (beta-coefficient [beta]= -1.90 units, 95% CI: -3.40,-0.039), mental health (beta= -2.92 units, -4.31,-1.53) and global health (beta= -2.77 units, -4.21,-1.33) composite scores. In this selected group of weight loss trial participants, lower neighborhood SES was significantly associated with poorer health status. Whether these associations might influence response to the Look AHEAD weight loss intervention requires further investigation.

Despite the widespread use of percutaneous closure of patent foramen ovale (PFO) in patients after a cryptogenic stroke, little is known about its impact on health-related quality of life (HRQoL). The aim of this study was to assess HRQoL in these patients compared to PFO patients not considered candidates for percutaneous closure, and to a normal population. A total of 402 patients with cryptogenic stroke or transient ischaemic attack (TIA) who had been referred to our center for PFO closure were invited to a long-term clinical follow-up (mean follow-up 5.5 years; range 3-13 years). HRQoL was assessed using the SF-36 Health Survey and data were compared with an age- and gender-matched reference group from the Swedish SF-36 normative database. Fifteen patients had died and 43 did not answer the SF-36. Of the remaining 344 patients, 208 had undergone PFO closure, and 136 had not. The closure group and reference group reported similar HRQoL levels. However, the non-closure group showed significantly lower HRQoL in role limitation - physical, vitality, general health, mental health (p < 0.05) and social functioning (p = 0.05) than the reference group and also had significantly lower scores than the closure group, correcting for age differences, on physical functioning, role limitation - physical, vitality and general health (p < 0.05). Non-closure patients had lower HRQoL than their counterparts in the normal population and the closure group. Percutaneous PFO closure is associated with a favorable quality of life.

: To assess the effects of premenstrual disorders on health-related quality of life (HR-QOL), hobbies and social activities, and relationships with others in the multinational IMPACT study. : Women aged 15-45 years were screened for suspected premenstrual dysphoric disorder (PMDD) and premenstrual syndrome (PMS) and invited to participate in this web-based study. Based on the Daily Record of Severity of Problems (DRSP), prospectively assessed over two observational cycles, participants were grouped into two categories: no perceived symptoms/mild PMS or moderate-to-severe PMS/PMDD. HR-QOL was assessed retrospectively at baseline using the SF-12. : Overall, 1477 women started the study. Of these, 822 (56%) completed the DRSP and SF-12 questionnaires as planned. Moderate-to-severe PMS/PMDD was associated with a reduction in HR-QOL compared with no perceived symptoms/mild PMS for both mental component scores (34.5 ± 8.7 vs 39.0 ± 9.5) and physical component scores (48.9 ± 7.9 vs 51.1 ± 7.2). Women with moderate-to-severe PMS/PMDD experienced a significantly greater mean number of days with at least moderate interference with hobbies or social activities (5.6 vs 1.1 day; p < 0.05, t-test), and relationships with others (5.4 vs 1.1 day) than those with no perceived symptoms/mild PMS. : Moderate-to-severe PMS/PMDD has a negative impact on HR-QOL, hobbies and social activities, and relationships with others. Studies with a confirmatory design are needed to confirm these results.

To evaluate the health-related quality of life in Hong Kong Chinese patients with chronic non-cancer pain. Prospective cross-sectional survey. Regional public hospitals, Hong Kong. Patients attending out-patient pain management clinics between 1 July 2002 and 28 February 2003 were approached to complete a set of standardised questionnaires. Demographic profiles, treatment modality, litigation, compensation, social welfare status, Hospital Anxiety Depression Scale, and Medical Outcomes Survey short-form health survey (SF36). Data from 166 patients were analysed. The median numeric pain rating score was 6 (interquartile range, 2-10). Work-related injury occurred in 34.3% of patients, while another 34% were involved in pain-related litigation and 32% were receiving disability or unemployment benefit. Sixty-four percent of patients were managed by three or more disciplines, while 54.8% were also receiving complimentary alternative medical treatment, mainly traditional Chinese medicine (49.7%). The Hospital Anxiety Depression Score indicated clinical anxiety or depression in 71.1% of patients. All SF36 subscale scores were lower than the local population norm. Unemployed patients had higher depression scores (P = 0.005), while students or retirees had lower physical functioning scores (P = 0.004). Patients who were single had higher role emotion scores than those who were married or separated/widowed (P = 0.011). Logistic regression analysis showed that younger age (odds ratio = 0.95), being married (6.62), work-related injury (15.63) or higher general scores (1.03) were more likely to be associated with litigation. Social welfare benefit was associated with unemployment (3.39) and a lower level of physical functioning (0.98). There was a high prevalence of clinical anxiety, depression, and severe impairment in the health-related quality of life in Hong Kong Chinese patients with chronic non-cancer pain. Specific factors affected the health-related quality of life, likelihood of litigation, and social benefit.

Inadequate studies have been conducted in China to examine quality of life in family caregivers. Quality of life in family caregivers for elderly people with chronic diseases was evaluated, and the demographic and characteristic factors of both elderly people and their caregivers were explored. The 36-Item Short Form Health Survey (SF-36) was used to assess health-related quality of life in 407 family caregivers caring for elderly people with chronic diseases in six communities on the Mainland China. The explanatory variables included family caregivers' demographic and other caregiving variables related to eldercare. Descriptive statistics and multiple linear regression analysis were used in the data analysis, performed via SPSS 17.0. Mean SF-36 and physical and mental component scores were 66.14 ± 17.50, 70.06 ± 16.49, and 62.22 ± 18.51, respectively. The scores of caregivers' physical function and bodily pain were significantly higher, while the scores of caregivers' role limitations due to physical problems, general health, vitality, social function, mental health and role limitations due to emotional problems were significantly lower. Caregivers' ages, comorbidity, the perceived effects of caregiving on caregivers' social lives and elderly individuals' ages, marital status and Activities of Daily Living scores were significantly associated with the physical component score. In addition, caregivers' age, the affordability of the elderly person's healthcare expenses, the perceived effects of caregiving on caregivers' social lives, and elderly people's marital status and ADL scores were significantly associated with the mental component score. Family caregivers for elderly people with chronic diseases showed poorer mental and better physical well-being. Factors of both elderly people and their caregivers impact the caregivers' quality of life. These findings highlight the importance of addressing mental health of family caregivers, and of providing economical support and psychological care for them.

Cancer germline (CG) genes are normally expressed in germ cells and aberrantly expressed in a variety of cancers; their immunogenicity has led to the widespread development of cancer vaccines targeting these antigens. BORIS/CTCFL is an autosomal CG antigen and promising cancer vaccine target. BORIS is the only known paralog of CTCF, a gene intimately involved in genomic imprinting, chromatin insulation, and nuclear regulation. We have previously shown that BORIS is expressed in epithelial ovarian cancer (EOC) and that its expression coincides with promoter and global DNA hypomethylation. Recently, 23 different BORIS mRNA variants have been described, and have been functionally grouped into six BORIS isoform families (sf1–sf6). In the present study, we have characterized the expression of BORIS isoform families in normal ovary (NO) and EOC, the latter of which were selected to include two groups with widely varying global DNA methylation status. We find selective expression of BORIS isoform families in NO, which becomes altered in EOC, primarily by the activation of BORIS sf1 in EOC. When comparing EOC samples based on methylation status, we find that BORIS sf1 and sf2 isoform families are selectively activated in globally hypomethylated tumors. In contrast, CTCF is downregulated in EOC, and the ratio of BORIS sf1, sf2, and sf6 isoform families as a function of CTCF is elevated in hypomethylated tumors. Finally, the expression of all BORIS isoform families was induced to varying extents by epigenetic modulatory drugs in EOC cell lines, particularly when DNMT and HDAC inhibitors were used in combination.

A new type of surface-functionalized porous clay heterostructures (SF-PCH) was synthesized via carbonization of the template agents with sulfuric acid. The converted carbons deposited on the porous surface of the SF-PCH samples and changed their surface chemical properties. The composites possessed a maximum carbon content of 5.35%, a large specific surface area of 428 m2/g and micropore volume of approximately 0.2 cm3/g. The layered and porous structure of SF-PCH was retained after carbonization and calcination when sulfuric acid solution with a mild concentration was used. Analysis by XPS confirmed that the carbonaceous matter in the pore channels was functionalized with various organic groups, including carbonaceous, nitrogenous, and sulfated groups. Both the surface chemical property and structural characteristic of adsorbents have effects on the adsorption properties of SF-PCH for toluene. The SF-PCH samples exhibited a stronger adsorption affinity to toluene compared with untreated PCH in the low pressure region, which is more valuable in the practical applications. These results demonstrate that carbonization of soft-template is a feasible process for the surface modification of PCH, enabling the resulting composites to become promising candidates for application in toluene emission control.

Critical Race Theory and the Limits of Relational Theory in Social Work with Women.

The authors present a conceptual framework for expanding the use of relational theory with African-American women. Relational theory (RT) informs practice with women but is inadequate in addressing all aspects of culture and identity. RT presumes that all women desire or are able to make therapeutic connections, yet race, gender, and cultural experiences influence their ability to do so. Successful practice with minority women must address racism and its impact. Critical race theory (CRT) that incorporates a solution-focused (SF) approach is well-suited to address the limits of RT. This overview of a CRT/SF approach describes treatment for diverse women that extends RT and enhances effective social work practice to provide culturally sensitive treatment to women.

This pilot study examined the relationship between smoking, alcohol intake, depressive symptoms and quality of life (QoL) in head and neck cancer patients. A questionnaire on smoking, alcohol, depressive symptoms and QoL was distributed to head and neck cancer patients (N=81). Over one-third (35%) of the respondents had smoked within the last 6 months, 46% had drunk alcohol within the last 6 months and 44% screened positive for significant depressive symptoms. About one-third (32%) of smokers were interested in smoking cessation services and 37% of patients with depressive symptoms were interested in depression services. However, only 9% of those who drank alcohol expressed interest in alcohol services. Smoking was negatively associated with five scales of the SF-36V including Physical Functioning, General Health, Vitality, Social Functioning, and Role-Emotional Health. Depressive symptoms were negatively associated with all eight scales on the SF-36V and all four scales of the Head and Neck Quality of Life instrument. Surprisingly, alcohol was not found to be associated with any of the QoL scales. While smoking, alcohol intake and depression may be episodically treated, standardized protocols and aggressive intervention strategies for systematically addressing these highly prevalent disorders are needed in this population.

Objective This was a comparative analysis on the quality of life of patients who underwent hemiarthroplasty of the hip, assessed before the operation and 3 and 6 months after the operation, by means of the SF-36 questionnaire (Medical Outcomes Study 36-Item Short Form health survey). Methods A prospective study was conducted on 12 patients with femoral neck fractures who underwent partial hip arthroplasty between June 2013 and July 2014. Female patients predominated (58.3%). The mean age was 83 years and, in 91.7%, the fracture was due to falling from a standing position. The SF-36 questionnaire was applied before the operation and 3 and 6 months after the operation. Results With regard to physical health, the patients presented low scores for functional capacity and physical aspects. They had good scores for the subitem of general state and high scores regarding pain. Vitality, social aspect and mental health had moderate scores and emotional aspects had a low score. Conclusion With the sample analyzed here, we can say that the hip hemiarthroplasty procedure for cases of unstable femoral neck fractures, in patients with low functional demands analyzed over a postoperative period of 6 months, does indeed allow quality of life to be maintained.

Studies have shown that Mindfulness Based Stress Reduction (MBSR) has positive effect on physical and psychological dimensions of chronic illnesses. In this study for the first time we examine the effect of this new technique on quality of life and pulmonary function in chemically pulmonary injured veterans who have chronic pulmonary problem, psychological problems and low quality of life. Forty male pulmonary injured veterans were randomly replaced in two groups with 20 participants (MBSR and control Wait List (WL)). Then MBSR group received 8-weekly sessions intervention. We evaluate quality of life (used SF-36 questionnaire) and Spirometry parameters two times; before and after intervention in two group. We used "mixed factorial analyses of variance" test for analyzing data in each dependent variables. Then if we have significant interactional effect, we used -paired- sample t-test" for comparing before and after intervention data of each group, and "Independent-Sample t-test" for comparing after intervention data of two groups. The MBSR compare to WL group improved SF-36 total score, (F (1, 38) =12.09, P=0.001), "Role limitations due to physical problems"(F(1,38)= 6.92, P=0.01), "Role limitations due to emotional problems"(F(1,38)= 7.75, P=0.008), "Social functioning"(F(1,38)= 9.89, P=0.003), "Mental health"(F(1,38)= 15.93, P=0), "Vitality"(F(1,38)= 40.03, P≤0.001), and "Pain"(F(1,38)= 27.60, P≤0.001). MBSR had no significant effect on "FEV1" (F (1, 38) = 0.03, P=0.85),"FVC" (F (1, 38) = 0.16, P=0.69) and "FEV1/FVC" (F (1, 38) = 2.21, P=0.14). MBSR can improve individual's quality of life but not lung function in chemically pulmonary injured veterans.

SF-1 a key player in the development and differentiation of steroidogenic tissues

Val, Pierre; Lefrançois-Martinez, Anne-Marie; Veyssière, Georges; Martinez, Antoine

2003-01-01

Since its discovery in the early 1990s, the orphan nuclear receptor SF-1 has been attributed a central role in the development and differentiation of steroidogenic tissues. SF-1 controls the expression of all the steroidogenic enzymes and cholesterol transporters required for steroidogenesis as well as the expression of steroidogenesis-stimulating hormones and their cognate receptors. SF-1 is also an essential regulator of genes involved in the sex determination cascade. The study of SF-1 null mice and of human mutants has been of great value to demonstrate the essential role of this factor in vivo, although the complete adrenal and gonadal agenesis in knock-out animals has impeded studies of its function as a transcriptional regulator. In particular, the role of SF-1 in the hormonal responsiveness of steroidogenic genes promoters is still a subject of debate. This extensive review takes into account recent data obtained from SF-1 haploinsufficient mice, pituitary-specific knock-outs and from transgenic mice experiments carried out with SF-1 target gene promoters. It also summarizes the pros and cons regarding the presumed role of SF-1 in cAMP signalling. PMID:14594453

Perceived social support and hearing handicap were assessed in adults with and without hearing loss who lived in different geographical regions of Alabama. The Hearing Handicap Inventory for Adults (HHIA) assessed emotional and social consequences of hearing loss. The Medical Outcomes Study (MOS) Social Support Survey and the Social Functioning, Role Emotional and Mental Health scales of the SF-36 were administered. Data were collected from 71 study participants with hearing loss and from 45 adults without hearing loss. Degree of hearing loss and outcomes from the HHIA did not differ between adults who lived in rural or urban settings. Tangible support was poorer for adults with hearing loss who lived in rural settings compared to those who lived in urban settings. For adults without hearing loss, residency was not associated with tangible support. For these adults, income was associated with other types of social support (i.e. informational support, affection, positive social interaction). Adults with hearing loss living in rural areas had poor perceived tangible support. The provision of support to address a hearing loss could be worse for these adults compared to adults who lived in urban settings.

Characterization of street food consumption in palermo: possible effects on health

PubMed Central

2011-01-01

Background Street Food (SF) consists of out-of-home food consumption and has old, historical roots with complex social-economic and cultural implications. Despite the emergence of modern fast food, traditional SF persists worldwide, but the relationship of SF consumption with overall health, well-being, and obesity is unknown. Methods This is an observational, cross-sectional study. The study was performed in Palermo, the largest town of Sicily, Italy. Two groups were identified: consumers of SF (n = 687) and conventional restaurant food (RES) consumers (n = 315). Study subjects answered a questionnaire concerning their health conditions, nutritional preferences, frequency of consumption of SF and a score relative to SF consumption ranging from 0 to 20 was calculated. Results Body mass index (BMI, kg/m2) was significantly and independently correlated with the score of street food consumption (r = 0,103; p < 0.002). The prevalence of different diseases, including hypertension and type 2 diabetes, and the use of medications did not differ between the two groups. Milza (a sandwich stuffed with thin slice of bovine spleen and lung) consumers had a significantly higher prevalence of hypertension (12.2% vs 6.2% in non consumers; p < 0.005) and in this subgroup the use of anti-hypertensive drugs was inversely correlated with the frequency of milza consumption (r = 0.11; P = 0.010). Conclusions This study suggests that SF consumption in Palermo is associated with a higher BMI and higher prevalence of hypertension in milza consumers. Further studies should evaluate whether frequent SF consumers have unfavourable metabolic and cardiovascular profile. PMID:22034903

Steroidogenic factor-1 (SF-1, NR5A1) and human disease

2011-01-01

Steroidogenic factor-1 (SF-1, Ad4BP, encoded by NR5A1) is a key regulator of adrenal and reproductive development and function. Based upon the features found in Nr5a1 null mice, initial attempts to identify SF-1 changes in humans focused on those rare individuals with primary adrenal failure, a 46,XY karyotype, complete gonadal dysgenesis and Müllerian structures. Although alterations affecting DNA-binding of SF-1 were found in two such cases, disruption of SF-1 is not commonly found in patients with adrenal failure. In contrast, it is emerging that variations in SF-1 can be found in association with a range of human reproductive phenotypes such as 46,XY disorders of sex development (DSD), hypospadias, anorchia, male factor infertility, or primary ovarian insufficiency in women. Overexpression or overactivity of SF-1 is also reported in some adrenal tumors or endometriosis. Therefore, the clinical spectrum of phenotypes associated with variations in SF-1 is expanding and the importance of this nuclear receptor in human endocrine disease is now firmly established.

A short version of the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) function scale has recently been developed to enhance the applicability of the scale in routine practice and clinical research for patients with hip and knee osteoarthritis. The goal of the present study was to validate this short form. We conducted a prospective 4-week cohort study of 1,036 outpatients. Performance on the WOMAC function long form (LF) and short form (SF) was compared. Agreement between responses on the 2 forms was examined according to a Bland-Altman plot. Responsiveness to change (by standardized response mean [SRM]), reproducibility (intraclass correlation coefficient [ICC]), and internal consistency (Cronbach's alpha) were computed for both forms. Construct validity was assessed based on functional impairment as measured on a numerical rating scale. At baseline, 24% of patients who completed the WOMAC LF had missing data for at least 1 item as compared with only 6% of patients who completed the WOMAC SF. The mean WOMAC SF score was greater than the mean WOMAC LF score (mean +/- SD difference -4.3 +/- 4.8 on a 0-100 scale). SRMs were 0.61 and 0.73, ICCs were 0.76 and 0.68, and Cronbach's alphas were 0.93 and 0.85 for the WOMAC LF and SF, respectively. The 2 forms had comparable correlation with functional impairment. The WOMAC function short form has a low rate of missing data and is a responsive, reproducible, and valid measure. The mean SF score was 4 points higher than the mean LF score.

A systematic review of reviews was conducted to identify and appraise brief measures of health-related quality of life (HRQoL) that have been used in peer-reviewed research with people living with HIV. The review was conducted in two stages: 1) search of electronic databases to identify systematic reviews of tools used to measure HRQoL in adults living with HIV, published since the year 2000; 2) selection of HRQol scales from those identified in the reviews. Inclusion criteria included scales that could be self-administered in 10 min or less, covering at least 3 domains of quality of life (physical function, social/role function and mental/emotional function). For generic scales, inclusion criteria included the availability of normative data while for HIV-specific scales, patient input into the development of the scale was required. Ten reviews met the inclusion criteria. Nine generic scales met the inclusion criteria: the EuroQol five dimensions questionnaire (EQ-5D); Health Utilities Index; McGill Quality of Life questionnaire; Medical Outcomes Study (MOS) Short Form (SF)-12; SF-36; World Health Organisation Quality of Life (WHOQOL- BREF), Questions of Life Satisfaction (FLZM) and SF-20. Available psychometric data supported the EQ-5D and SF-36. Seven HIV-specific scales met the inclusion criteria: the AIDS Clinical Trials Group (ACTG)-21; HIV-QL-31; MOS-HIV; Multidimensional Quality of Life Questionnaire for Persons with HIV/AIDS (MQOL-HIV), PROQOL-HIV, Symptom Quality of Life Adherence (HIV-SQUAD) and the WHOQOL-HIV BREF. Of the HIV -specific measures, the MOS-HIV was considered to have the most well-established psychometric properties, however limitations identified in the reviews included insufficient input from people living with HIV in the development of the scale, cross-cultural relevance and continued applicability. Two relatively new measures, the WHOQOL-HIV BREF and PROQOL-HIV, were considered to have promising psychometric properties and may have more relevance to people living with HIV. The findings highlight the need for further validation of HRQoL measures in people living with HIV. The choice of one measure over another is likely to be influenced by the purpose of the quality of life assessment and the domains of HRQoL that are most relevant to the specific research or clinical question.

Which is the best method for human ovarian tissue cryopreservation: slow freezing/rapid thawing (SF/RT) or vitrification/warming (V/W)? The conventional SF/RT protocol used in this study seems to better preserve the morpho-functional status of human cryopreserved ovarian tissue than the used open carrier V/W protocol. Cryopreservation of human ovarian tissue is generally performed using the SF/RT method. However, reduction in the follicular pool and stroma damage are often observed. An emerging alternative procedure is represented by V/W which seems to allow the maintenance of the morphological integrity of the stroma. This is a retrospective cohort study including six patients affected by oncological diseases and enrolled from January to December 2014. Ovarian tissue was laparoscopically harvested from the right and left ovaries and was cryopreserved using a routinary SF/RT protocol or a V/W method, involving tissue incubation in two solutions (containing propylene glycol, ethylene glycol and sucrose at different concentrations) and vitrification in an open system. For each patient, three pieces from each ovary were collected at the time of laparoscopy (fresh tissue) and after storage (SF/RT or V/W) and processed for light microscopy (LM) and transmission electron microscopy (TEM), to assess the morphological and ultrastructural features of follicles and stroma, and for laser scanning confocal microscopy (LSCM), to determine the functional energetic/redox stroma status. The preservation status of SF/RT and V/W ovarian tissues was compared with that of fresh ones, as well as between them. By LM and TEM, SF/RT and V/W samples showed cryodamage of small entity. Interstitial oedema and increased stromal cell vacuolization and chromatin clumping were observed in SF/RT samples; in contrast, V/W samples showed oocyte nuclei with slightly thickened chromatin and irregular shapes. The functional imaging analysis by LSCM revealed that the mitochondrial activity and intracellular reactive oxygen species levels were reduced both in SF/RT and in V/W samples compared with fresh samples. The study also showed progressive dysfunction of the mitochondrial activity going from the outer to the inner serial section of the ovarian cortex. The reduction of mitochondrial activity of V/W samples compared with fresh samples was significantly higher in the inner section than in the outer section. The results report the bioenergetic and oxidative status assessment of fresh and cryopreserved human ovarian tissue by LSCM, a technique recently applied to tissue samples. The use of LSCM on human ovarian tissues after SF/RT or V/W is a new application that requires validation. The procedures for mitochondrial staining with functional probes and fixing are not yet standardized. Xenografting of the cryopreserved ovarian tissue in severe combined immunodeficient mice and in vitro culture have not yet been performed. The identification of a cryopreservation method able to maintain the morpho-functional integrity of the ovarian tissue and a number of follicles comparable with those observed in fresh tissue might optimize results in clinical practice, in terms of recovery, duration of ovarian function and increased delivery outcomes after replanting. The SF/RT protocol allowed better morpho-functional tissue integrity than the V/W procedure. Funding was provided by Fondazione del Monte di Bologna e Ravenna, Italy.

As a contribution to the functionality of nerve guide conduits (NGCs) in nerve tissue engineering, here we report a conduit processing technique through introduction and evaluation of topographical, physical and chemical cues. Porous structure of NGCs based on freeze-dried silk/single walled carbon nanotubes (SF/SWNTs) has shown a uniform chemical and physical structure with suitable electrical conductivity. Moreover, fibronectin (FN) containing nanofibers within the structure of SF/SWNT conduits produced through electrospinning process have shown aligned fashion with appropriate porosity and diameter. Moreover, fibronectin remained its bioactivity and influenced the adhesion and growth of U373 cell lines. The conduits were then implanted to 10 mm left sciatic nerve defects in rats. The histological assessment has shown that nerve regeneration has taken places in proximal region of implanted nerve after 5 weeks following surgery. Furthermore, nerve conduction velocities (NCV) and more myelinated axons were observed in SF/SWNT and SF/SWNT/FN groups after 5 weeks post implantation, indicating a functional recovery for the injured nerves. With immunohistochemistry, the higher S-100 expression of Schwann cells in SF/SWNT/FN conduits in comparison to other groups was confirmed. In conclusion, an oriented conduit of biocompatible SF/SWNT/FN has been fabricated with acceptable structure that is particularly applicable in nerve grafts. PMID:24098649

Whether the short-term effect of cardiac rehabilitation (CR) in elderly patients with heart failure (HF) is influenced by nutritional status is uncertain, so the present study investigated the effect of nutritional status on functional recovery after CR in elderly HF inpatients.Methods and Results:We enrolled 145 patients admitted for treatment of HF who were aged ≥65 years and had a low functional status defined as a Barthel index (BI) score ≤85 points at the commencement of CR. Nutritional status was assessed by the Mini Nutritional Assessment Short Form (MNA-SF) and total energy intake per day. The primary endpoint was functional status determined by the BI score at discharge. The median CR period was 20 days (interquartile range: 14-34 days), and 87 patients (60%) were functionally dependent (BI score ≤85) at discharge. Multivariate logistic regression analysis showed that MNA-SF score (odds ratio [OR]: 0.76, P=0.02) and total energy intake at the commencement of CR (OR: 0.91, P=0.02) were independent predictors of functional dependence after CR. MNA-SF score ≤7 and total energy intake ≤24.5 kcal/kg/day predicted functional dependence at discharge with moderate sensitivity and specificity. MNA-SF score and total energy intake at the commencement of CR are novel predictors of the extent of functional recovery of elderly HF inpatients after in-hospital CR.

The genome of Spodoptera frugiperda multiple nucleopolyhedrovirus (NPV) was inserted into a bacmid (Sfbac) and used to produce a mutant lacking open reading frame 29 (Sf29null). Sf29null bacmid DNA was able to generate an infection in S. frugiperda. Approximately six times less DNA was present in occlusion bodies (OBs) produced by the Sf29null bacmid in comparison to viruses containing this gene. This reduction in DNA content was consistent with fewer virus particles being packaged within Sf29null bacmid OBs, as determined by fractionation of dissolved polyhedra and comparison of occlusion-derived virus (ODV) infectivity in cell culture. DNA from Sfbac, Sf29null, or Sf29null-repair, in which the gene deletion had been repaired, were equally infectious when used to transfect S. frugiperda. All three viruses produced similar numbers of OBs, although those from Sf29null were 10-fold less infectious than viruses with the gene. Insects infected with Sf29null bacmid died ∼24 h later than positive controls, consistent with the reduced virus particle content of Sf29null OBs. Transcripts from Sf29 were detected in infected insects 12 h prior to those from the polyhedrin gene. Homologs to Sf29 were present in other group II NPVs, and similar sequences were present in entomopoxviruses. Analysis of the Sf29 predicted protein sequence revealed signal peptide and transmembrane domains, but the presence of 12 potential N-glycosylation sites suggest that it is not an ODV envelope protein. Other motifs, including zinc-binding and threonine-rich regions, suggest degradation and adhesion functions. We conclude that Sf29 is a viral factor that determines the number of ODVs occluded in each OB. PMID:18550678

Currently, several fatigue measurement instruments are available to evaluate and measure cancer-related fatigue. Amongst them, Multidimensional Fatigue Syndrome Inventory-Short Form (MFSI-SF) is a self-reported instrument and a multidimensional scale that aims to capture the global, somatic, affective, cognitive and behavioural symptoms of fatigue. This study examines the psychometric properties and measurement equivalence of the English and Chinese versions of MFSI-SF in breast cancer and lymphoma patients in Singapore. Patients were recruited from National Cancer Centre Singapore. Validity, reliability and responsiveness of MFSI-SF were evaluated in this study. Convergent validity was evaluated by correlating total and subscales of MFSI-SF to known related constructs in EORTC QLQ-C30. Known group validity was assessed based on patients' cancer stage, pain, insomnia and depression symptoms. Reliability was evaluated by Cronbach's α. Responsiveness analyses were performed with patients who have undergone at least one cycle of chemotherapy. Multiple regression was used to compare the total and subscale scores of MSFI-SF between the two language versions. Data from 246 (160 English and 86 Chinese version) breast cancer and lymphoma patients were included in the study. Moderate to high correlations were observed between correlated MFSI-SF subscales and EORTC QLQ-C30 domains (|r| = 0.524 to 0.774) except for a poor correlation (r = 0.394) observed between MFSI-SF vigour subscale and EORTC QLQ-C30 role functioning subscale. Total MFSI-SF scores could differentiate between patients with higher depression, pain and insomnia status. Internal consistency of MFSI-SF was also high (α = 0.749 to 0.944). Moderate correlation was observed between change in total MFSI-SF score and change in fatigue symptom scale score and global QoL score on EORTC QLQ-C30 (|r| = 0.478 and 0.404 respectively). Poor correlations were observed between change in scores of hypothesised subscales (|r| = 0.202 to 0.361) except for a moderate correlation between change in MFSI-SF emotional fatigue score and change in EORTC QLQ-C30 emotional functioning domain score. Measurement equivalence was established for all subscales and total MFSI-SF score except for the emotional and vigour subscales. This study supports the use of MFSI-SF as a reasonably valid scale with good internal consistency for measuring fatigue levels in the Singapore cancer population.

We aimed to assess quality of life (QOL) among Saudi hemodialysis (HD) patients and the impact on the QOL of a certain demographic and clinical factors. The QOL was assessed using an Arabic version of Kidney Disease Quality of Life Instrument Short Form (KDQOL-SF). Mean scores were compared for individual domain scores and for the three composite summary scores, namely the mental component score (MCS), the physical component score (PCS) and kidney-disease component score (KDCS). The study included one hundred chronic HD patients from King Abdulaziz Medical City, Riyadh. The overall mean score was 60.4. Domains with very low scores were "cognitive function", "role-emotional", "role-physical" and "work status". Domains with high scores were "patient satisfaction", "dialysis staff encouragement" and "quality of social interaction". The mean scores for "KDCS", "MCS" and "PCS" were 59.7, 54.2 and 52.7 respectively. KDC scores were higher among males and the married group. PCS scores were higher among males, patients aged < 40 years, and the higher income group. MCS scores were higher among males and the higher income groups. There was a positive correlation between "KDCS" and "MCS"(r=0.62, P=0.0001); and between "KDCS" and "PCS" (r=0.65, P=0.0001). The current study provides a detailed description of the QOL scores of a group of Saudi HD patients and the impact of certain factors on their QOL. Low scores were seen in the "work status", "cognitive function", "role-physical" and "role-emotional" while high scores were seen in "patient satisfaction", "dialysis staff encouragement" and "quality of social interaction" domains.

The object of this study was to examine the effect of population-based disease management and case management on resource use, self-reported health status, and member satisfaction with and retention in a Medicare Plus Choice health maintenance organization (HMO). Study design consisted of a prospective, randomized controlled open trial of 18 months' duration. Participants were 8504 Medicare beneficiaries aged 65 and older who had been continuously enrolled for at least 12 months in a network model Medicare Plus Choice HMO serving a contiguous nine-county metropolitan area. Members were care managed with an expert clinical information system and frequent telephone contact. Main outcomes included self-reported health status measured by the Medical Outcomes Study 36-Item Short-Form Health Survey (SF-36), resource use measured by admission rates and bed-days per thousand per year, member satisfaction, and costs measured by paid claims. More favorable outcomes occurred in the intervention group for satisfaction with the health plan (P < .01) and the social function domain as measured by SF-36 (P = .04). There was no difference in member retention or mortality between groups. Use of skilled nursing home services was significantly lower in the intervention group than in the control (616 vs 747 days per thousand members per year, P = .02). This reduction, however, did not lead to lower mean total expenditures in the intervention group compared with the control (6828 dollars per member for 18 months vs 7001 dollars, P = .61). Population-based disease management and case management led to improved self-reported satisfaction and social function but not to a global net decrease in resource use or improved member retention.

The aim of this paper is to review the literature on the effect of lower urinary tract symptoms (LUTS) on sexual function and dysfunction. At the International Consultation on Incontinence-Research Society (ICI-RS) in 2015, a multidisciplinary group presented a literature search of what is known about the effect of lower urinary tract dysfunction (LUTD) on sexual function (SF) in men and women. Wider discussions regarding knowledge gaps and ideal research methodology ensued. A body of evidence supports associations between LUTS/urinary incontinence on SF in both men and women, but the true prevalence of the impact of LUTD on SF remains largely unknown. There is still reluctance among health care professionals (HCP's) to discuss SF with patients and often patients who are not asked will not volunteer their problems. A significant knowledge gap in this area remains. Education among HCP's on assessment and treatment of sexual dysfunction and communication skills are essential to encourage, and engage patients with HCP's. Neurourol.

Traditional patient-reported physical function instruments often poorly differentiate patients with mild-to-moderate disability. We describe the development and psychometric evaluation of a generic item bank for measuring everyday activity limitations in outpatient populations. Seventy-two items generated from patient interviews and mapped to the International Classification of Functioning, Disability and Health (ICF) domestic life chapter were administered to 1128 adults representative of the Dutch population. The partial credit model was fitted to the item responses and evaluated with respect to its assumptions, model fit, and differential item functioning (DIF). Measurement performance of a computerized adaptive testing (CAT) algorithm was compared with the SF-36 physical functioning scale (PF-10). A final bank of 41 items was developed. All items demonstrated acceptable fit to the partial credit model and measurement invariance across age, sex, and educational level. Five- and ten-item CAT simulations were shown to have high measurement precision, which exceeded that of SF-36 physical functioning scale across the physical function continuum. Floor effects were absent for a 10-item empirical CAT simulation, and ceiling effects were low (13.5%) compared with SF-36 physical functioning (38.1%). CAT also discriminated better than SF-36 physical functioning between age groups, number of chronic conditions, and respondents with or without rheumatic conditions. The Rasch assessment of everyday activity limitations (REAL) item bank will hopefully prove a useful instrument for assessing everyday activity limitations. T-scores obtained using derived measures can be used to benchmark physical function outcomes against the general Dutch adult population.

End-stage chronic kidney disease (CKD) requiring dialysis affects the quality of life sometimes more severely than other chronic diseases, such as rheumatoid arthritis, heart failure, coronary artery disease, and chronic obstructive pulmonary disease, exerting a negative effect on the energy and vitality levels, limiting social interactions, and hindering psychic health. To evaluate the quality of life of patients with CKD on hemodialysis in a public Brazilian Amazonian hospital. Data were collected through interview based on the Brazilian version of the SF-36 questionnaire. The study was conducted on 50 patients (mean age, 48 ± 16 years; mean hemodialysis time, 3 ± 2.9 years). The most affected domain was role limitations due to physical health, with a mean score of 36 ± 36, and 58% of the patients in the lowest quartile, while mental health and social functioning were relatively preserved, with most patients in the highest quartile. Men obtained poorer scores than women did for role limitations due to physical health and vitality. Age correlated negatively with physical functioning. Patients on hemodialysis for more than one year had better scores in the social functioning domain, with a positive correlation between dialysis time and physical functioning. The domains assessed were globally impaired in the population studied, especially regarding role limitations due to physical health, suggesting that chronic disease with prolonged treatment has a negative influence on those domains.

The aims of this study were to estimate covariance components for BW at 270 d (BW270) and carcass and ham quality traits in heavy pigs using models accounting for social effects and to compare the ability of such models to fit the data relative to models ignoring social interactions. Phenotypic records were from 9,871 pigs sired by 293 purebred boars mated to 456 crossbred sows. Piglets were born and reared at the same farm and randomly assigned at 60 d of age to groups (6.1 pigs per group on average) housed in finishing pens, each having an area of 6 m(2). The average additive genetic relationship among group mates was 0.11. Pigs were slaughtered at 277 ± 3 d of age and 169.7 ± 13.9 kg BW in groups of nearly 70 animals each. Four univariate animal models were compared: a basic model (M1) including only direct additive genetic effects, a model (M2) with nonheritable social group (pen) effects in addition to effects in M1, a model (M3) accounting for litter effects in addition to M2, and a model (M4) accounting for social genetic effects in addition to effects in M3. Restricted maximum likelihood estimates of covariance components were obtained for BW270; carcass backfat depth; carcass lean meat content (CLM); iodine number (IOD); and linoleic acid content (LIA) of raw ham subcutaneous fat; subcutaneous fat depth in the proximity of semimembranosus muscle (SFD1) and quadriceps femoris muscle (SFD2); and linear scores for ham round shape (RS), subcutaneous fat (SF), and marbling. Likelihood ratio tests indicated that, for all traits, M2 fit the data better than M1 and that M3 was superior to M2 except for SFD1 and SFD2. Model M4 was significantly better than M3 for BW270 (P < 0.001) and CLM, IOD, RS, and SF (P < 0.05). The contribution of social genetic effects to the total heritable variance was large for CLM and BW270, ranging from 33.2 to 35%, whereas the one for ham quality traits ranged from 6.8 (RS) to 11.2% (SF). Direct and social genetic effects on BW270 were uncorrelated, whereas there was a negative genetic covariance between direct and social effects on CLM, IOD, RS, and SF, which reduced the total heritable variance. This variance, measured relative to phenotypic variance, ranged from 21 (CLM) to 54% (BW270). Results indicate that social genetic effects affect variation in traits relevant for heavy pigs used in dry-cured hams manufacturing. Such effects should be exploited and taken into account in design of breeding programs for heavy pigs.

Few epidemiologic studies have assessed health-related quality of life (HRQL) of asthma patients from a general population and it is unclear which instrument is best suitable for this purpose. We investigated the validity of the Asthma Quality of Life Questionnaire (AQLQ) and the SF-36 completed by individuals with asthma from the population-based SAPALDIA (Swiss study on air pollution and lung diseases in adults) cohort. The study included 258 participants with a physician-diagnosed asthma who had completed the AQLQ and SF-36. We assessed floor and ceiling effects, internal consistency reliability and cross-sectional validity with a priori hypotheses that correlations between the specific HRQL domains (e.g. "symptoms" or "physical functioning") and the corresponding external validation measures (respiratory symptoms, need for doctor visits, limitation in activities due to asthma and lung function) would capture similar aspects and be correlated moderately (> or = 0.3) to strongly (> or = 0.5), whereas non-corresponding domains be correlated weakly with each other (<0.3). The AQLQ showed pronounced ceiling effects with all median domain scores above 6 (scores varied from 1-7). For the SF-36, ceiling effects were present in 5 out of 8 domains. Cronbach's alpha was >0.7 for all AQLQ and SF-36 domains. Correlations between the AQLQ domains "respiratory symptoms", "activity limitation" and "environmental exposure", and the validation measures ranged from 0.29-0.57. Correlations between the "emotional function" domain and the validation measures were also in this range (0.31-0.55) and not as low as we hypothesized. For the SF-36, correlations between "physical functioning" and "role physical", and the validation measures ranged from 0.25-0.56, whereas "role emotional" and "mental health" correlated with these measures from 0.01-0.23. The AQLQ and the SF-36 showed fairly good internal consistency. Both instruments are limited by ceiling effects, but they appear less pronounced in the SF-36, which also shows a better discrimination between different aspects of HRQL. The SF-36 may therefore be a more valid measure of HRQL than the AQLQ when applied to individuals with asthma from the general population.

Background Chronic sleep fragmentation (SF) increases cancer aggressiveness in mice. Exosomes exhibit pleiotropic biological functions, including immune regulatory functions, antigen presentation, intracellular communication and inter-cellular transfer of RNA and proteins. We hypothesized that SF-induced alterations in biosynthesis and cargo of plasma exosomes may affect tumor cell properties. Results SF-derived exosomes increased tumor cell proliferation (~13%), migration (~2.3-fold) and extravasation (~10%) when compared to exosomes from SC-exposed mice. Similarly, Pre exosomes from OSA patients significantly enhanced proliferation and migration of human adenocarcinoma cells compared to Post. SF-exosomal cargo revealed 3 discrete differentially expressed miRNAs, and exploration of potential mRNA targets in TC1 tumor cells uncovered 132 differentially expressed genes that encode for multiple cancer-related pathways. Methods Plasma-derived exosomes from C57/B6 mice exposed to 6 wks of SF or sleep control (SC), and from adult human patients with obstructive sleep apnea (OSA) before (Pre) and after adherent treatment for 6 wks (Post) were co-cultured with mouse lung TC1 or human adenocarcinoma tumor cell lines, respectively. Proliferation, migration, invasion, endothelial barrier integrity and extravasation assays of tumor cells were performed. Plasma mouse exosomal miRNAs were profiled with arrays, and transcriptomic assessments of TC1 cells exposed to SF or SC exosomes were conducted to identify gene targets. Conclusions Chronic SF induces alterations in exosomal miRNA cargo that alter the biological properties of TC1 lung tumor cells to enhance their proliferative, migratory and extravasation properties, and similar findings occur in OSA patients, in whom SF is a constitutive component of their sleep disorder. Thus, exosomes could participate, at least in part, in the adverse cancer outcomes observed in OSA. PMID:27419627

Depressive disorders have a large impact on psychosocial functioning. Since lower functioning predicts recurrence of a depressive episode, insight into the post-morbid course of psychosocial functioning of persons with different depressive disorders may facilitate recurrence prevention. Data were derived from NEMESIS, an epidemiologic survey in the adult population in the Netherlands. Respondents, who met the CIDI criteria of major depression (MDD; n=102), dysthymic disorder (Dysth; n=66) or double depression (DD; n=73) at baseline, and recovered during three year follow-up, were included; as was a control group without any diagnosis (NoDiag, n=4140). Functioning was assessed using the Groningen Social Disability Schedule (GSDS) and the SF-36 physical health summary-scale. Linear Mixed Models were conducted to compare 3-year trajectories of functioning across depressive groups and with NoDiag group. Compared to NoDiag, all depressed groups were significantly impaired on social and physical functioning. Dysth and DD had a lower level of post-morbid physical functioning compared to MDD (after 1 and 3 years respectively: Dysth: B=-13.8, p=.002 and B=-8.11, p=.09; DD: B=-8.9, p=.03 and B=-9.1, p=.05). Determinants for impaired social functioning (neuroticism) and for impaired physical functioning (age, comorbid somatic disorders and neuroticism) were identified. Attrition was higher among persons with a depression. Inclusion of the drop-outs would most likely have resulted in stronger associations, since we expect lower functioning among the drop-outs. This study indicates the long-term debilitating effects of psychopathology, even after recovery of depressive disorders. Duration of the index symptoms appears to be associated with impaired functioning, since especially those with Dysthymia (either with or without a MDD) showed slower and less recovery of functioning.

Transsexualism is the most extreme form of gender identity disorder and most transsexuals eventually pursue sex reassignment surgery (SRS). In transsexual women, this comprises removal of the male reproductive organs, creation of a neovagina and clitoris, and often implantation of breast prostheses. Studies have shown good sexual satisfaction after transition. However, long-term follow-up data on physical, mental and sexual functioning are lacking. To gather information on physical, mental, and sexual well-being, health-promoting behavior and satisfaction with gender-related body features of transsexual women who had undergone SRS. Fifty transsexual women who had undergone SRS >or=6 months earlier were recruited. Self-reported physical and mental health using the Dutch version of the Short-Form-36 (SF-36) Health Survey; sexual functioning using the Dutch version of the Female Sexual Function Index (FSFI). Satisfaction with gender-related bodily features as well as with perceived female appearance; importance of sex, relationship quality, necessity and advisability of gynecological exams, as well as health concerns and feelings of regret concerning transition were scored. Compared with reference populations, transsexual women scored good on physical and mental level (SF-36). Gender-related bodily features were shown to be of high value. Appreciation of their appearance as perceived by others, as well as their own satisfaction with their self-image as women obtained a good score (8 and 9, respectively). However, sexual functioning as assessed through FSFI was suboptimal when compared with biological women, especially the sublevels concerning arousal, lubrication, and pain. Superior scores concerning sexual function were obtained in those transsexual women who were in a relationship and in heterosexuals. Transsexual women function well on a physical, emotional, psychological and social level. With respect to sexuality, they suffer from specific difficulties, especially concerning arousal, lubrication, and pain.

Patients with inflammatory bowel disease (IBD) are at risk for psychiatric disorders that impact symptom experience and health-related quality of life (HRQOL). Therefore, comprehensive biopsychosocial assessments should be considered in ambulatory care settings. Patient-Reported Outcomes Measurement Information System (PROMIS) measures created by the National Institutes of Health have shown construct validity in a large IBD internet-based cohort, but their validity in ambulatory settings has not been examined. We sought to validate PROMIS patient-reported measures of HRQOL, functioning, and psychiatric symptom severity at a tertiary IBD clinic. Adult patients (n = 110) completed the PROMIS Global Health scale, PROMIS-29, SF-12, and WHODAS 2.0. Pearson's correlation coefficients (r) determined the relationships between scores to validate the PROMIS Global Health Physical and Mental metrics, compared with the SF-12 and WHODAS 2.0. We compared these measures by disease subtype of Crohn's disease or ulcerative colitis. PROMIS measures were highly correlated (r range = 0.64-0.82) with standard measures of HRQOL and functioning. On the PROMIS Global Health measures, 20.9% had impaired physical health, and 13.7% had impaired mental health. Impairments were reported in pain interference (20% of patients), anxiety (18.2%), satisfaction with social role (15.5%), physical functioning (10.9%), fatigue (10%), depression (7.3%), and sleep disturbance (5.5%). Patients with Crohn's disease had worse scores than those with ulcerative colitis on measures of the global physical health (P = 0.027), physical functioning (P = 0.047), and pain interference (P = 0.0009). PROMIS instruments provide valid assessment of HRQOL and functioning in ambulatory adults with IBD. Of note, patients with Crohn's disease demonstrated significantly worse impairments than those with ulcerative colitis.

Science fiction (SF) is often perceived as a ‘fringe’ form of entertainment that excites the socially challenged. This misperception detracts from the critical, scientific and interpretive nature of the genre which can be directed into science teaching at school and university levels as an innovative way of exploring the cultural background, politics, leitmotif and themes of society, science and their operation. One example is the ‘alien’ theme in SF; it is perceptually one of the driving factors in the search for extraterrestrial intelligence (SETI). Such a topic can become an introduction to current technology, the motives and politics of science and the sociological implications inherent in a confrontation with the ideal of man's uniqueness in the cosmos. When applied to the SETI, SF engenders a constructive convergence in studies such as biological determinism, the evolution of life, communication, interstellar travel and methods of contact, thus enriching the consideration of possible life in the cosmos. Adopting elements of SF in lifelong learning therefore enables informed, imaginative reflection and debate that educates, trains and instructs, broadening the potential of students and their future roles by invoking an analysis of vital public, scientific and humanistic fields.

OBJECTIVE—To compare the responsiveness of the condition-specific Western Ontario and McMaster Universities osteoarthritis (OA) index (WOMAC) and the generic Short Form-36 (SF-36) in patients with OA of the legs undergoing a comprehensive inpatient rehabilitation intervention.
METHODS—A prospective follow up study of consecutively referred inpatients of a rehabilitation clinic was made. The patients included fulfilled the American College of Rheumatology criteria for knee or hip OA and underwent both passive and, particularly, active physical therapy for three to four weeks. Responsiveness assessment was performed using the standardised response mean (SRM), effect size, and Guyatt's responsiveness statistic between admission and discharge (end of rehabilitation) and then again between admission and three months later. For pain and function the SRMs were stratified by sex and OA joint. Effects were tested by the t test and SRMs of different scales were compared by the jack knife test.
RESULTS—At the three month follow up, complete data were obtained for 223 patients. In general, the three responsiveness statistics showed a similar order of responsiveness. For both instruments, the pain scales were more responsive than the function scales. The responsiveness of the pain scale of both instruments was comparable (SRM=0.723 for WOMAC and SRM=0.528 for SF-36 at the end of rehabilitation; SRM=0.377 for WOMAC and SRM=0.468 for SF-36 at the three month follow up). In the measurement of function, the WOMAC was significantly more responsive than the SF-36 (SRMs, end of rehabilitation: 0.628 v 0.249; three month follow up: 0.235 v −0.001). Responsiveness tended to be higher in women and in knee OA than in men and hip OA.
CONCLUSIONS—Both instruments, the WOMAC and the SF-36, capture improvement in pain in patients undergoing comprehensive inpatient rehabilitation intervention. Functional improvement can be detected better by the WOMAC than by the SF-36. All the other scales of both instruments were more weakly responsive.

Pseudobulbar affect (PBA) is characterized by involuntary and uncontrollable laughing and/or crying episodes, occurring secondary to neurological disease or injury. The impact of PBA on social and occupational function, health status, quality of life (QOL), and quality of relationships (QOR) is not well studied. This US survey conducted by Harris Interactive compared health status and daily function of patients with and without PBA. Eligible respondents were Harris Panel Online registrants previously diagnosed with stroke, multiple sclerosis, Parkinson's disease, Alzheimer's disease, traumatic brain injury, or amyotrophic lateral sclerosis, or primary, nonpaid caregivers for such patients who were too debilitated to participate. PBA was identified by a Center for Neurologic Study lability scale score of 13 or greater. Measures included the 36-item short form health survey (SF-36), the work productivity and impairment (WPAI) questionnaire, visual analog scales (VAS) for impact of PBA symptoms on QOL and QOR, and customized questions related to burden and impact of involuntary laughing/crying episodes on patients' lives. Survey responses were weighted to adjust for the relative proportion of the primary neurological conditions in the overall population and between group differences in patient age and gender. PBA and non-PBA group responses were compared using two-tailed t tests adjusted for severity of the primary neurological conditions. The 1,052 respondents included 399 PBA group participants and 653 controls. The PBA group showed significantly worse scores versus non-PBA controls on component and summary SF-36 scores (P<0.05 for all), VAS scores (P<0.05 for both), and WPAI scores (P<0.05). Among PBA group respondents, PBA contributed a great deal to or was the main cause of patients becoming housebound for 24% and being moved to supervised living placement for 9% of respondents. PBA is associated with considerable burden incremental to that of the underlying neurological conditions, affecting QOL, QOR, health status, and social and occupational functioning.

The outbreak of Zika virus (ZIKV) and associated fetal microcephaly mandates efforts to understand the molecular processes of infection. Related flaviviruses produce noncoding subgenomic flaviviral RNAs (sfRNAs) that are linked to pathogenicity in fetal mice. These viruses make sfRNAs by co-opting a cellular exonuclease via structured RNAs called xrRNAs. We found that ZIKV-infected monkey and human epithelial cells, mouse neurons, and mosquito cells produce sfRNAs.

Shigella flexneri is a Gram-negative anaerobic bacterium that causes highly infectious bacterial dysentery in humans. Here, we solved the crystal structure of SF216, a hypothetical protein from the S. flexneri 5a strain M90T, at 1.7 Å resolution. The crystal structure of SF216 represents a homotrimer stabilized by intersubunit interactions and ion-mediated electrostatic interactions. Each subunit consists of three β-strands and five α-helices with the β-β-β-α-α-α-α-α topology. Based on the structural information, we also demonstrate that SF216 shows weak ribonuclease activity by a fluorescence quenching assay. Furthermore, we identify potential druggable pockets (putative hot spots) on the surface of the SF216 structure by computational mapping. © 2017 Federation of European Biochemical Societies.

Cross-sectional. To measure fear of movement/reinjury levels and determine the association with function at different timeframes during anterior cruciate ligament (ACL) reconstruction rehabilitation. We hypothesized that fear of movement/reinjury would decrease during rehabilitation and be inversely related with function. Fear of movement/reinjury can prevent return to sports after ACL reconstruction, but it has not been studied during rehabilitation. Demographic data and responses on the shortened version of Tampa Scale for Kinesiophobia (TSK-11), 8-Item Short-Form Health Survey (SF-8), and International Knee Documentation Committee (IKDC) subjective form were extracted from a clinical database for 97 patients in the first year after ACL reconstruction. Three groups were formed: group 1, less than or equal to 90 days; group 2, 91 to 180 days; group 3: 181 to 372 days post-ACL reconstruction. Group differences in TSK-11 score, SF-8 bodily pain rating, and IKDC scores were determined. Hierarchical linear regression models were created for each group, with IKDC score as the dependent variable and demographic factors, SF-8 bodily pain rating, and TSK-11 score as independent variables. TSK-11 score was higher in group 1 than in group 3 (P < .05). Across the groups, SF-8 bodily pain rating decreased (P < .001) and IKDC score increased (P < .001). SF-8 bodily pain rating was a significant factor in the regression model for all groups, whereas TSK-11 score only contributed to the regression model in group 3 (partial correlation, -0.529). Pain was consistently associated with function across the timeframes studied. Fear of movement/reinjury levels appear to decrease during ACL reconstruction rehabilitation and are associated with function in the timeframe when patients return to sports. Prognosis, level 4.

The relationship between traits optimism and anxiety and health-related quality of life in patients hospitalized for chronic diseases: data from the SATISQOL study

Background The impact of psychological factors is often taken into account in the evaluation of quality of life. However, the effect of optimism and trait anxiety remains controversial and they are rarely studied simultaneously. We aimed to study the effect of this factor on health-related quality of life (HRQOL) of patients after a hospitalization in relation with their chronic disease. Methods Using cross-sectional data from the SATISQOL cohort, we conducted a multicentric study, including patients hospitalized for an intervention in connection with their chronic disease. Six months after hospitalization, patients completed a generic HRQOL questionnaire (SF-36), and the STAI and LOT-R questionnaires to evaluate optimism and trait anxiety. We studied the effect of each trait on HRQOL separately, and simultaneously, taking account of their interaction in 3 models, using an ANOVA. Results In this study, 1529 patients were included in three participating hospitals and there existed wide diversity in the chronic diseases in our population. The HRQOL score increased for all dimensions of SF36 between 15,8 and 44,5 when the level of anxiety decreased (p < 0.0001) for the model 1, assessing the effect of anxiety on HRQOL and increased for all dimensions of SF36 between 3.1 and 12.7 with increasing level of optimism (< 0.0001) in the model 2 assessing the effect of optimism on HRQOL. In the model 3, assessing the effect of both anxiety and optimism on HRQOL, and their interaction, the HRQOL score for all dimensions of the SF36 increased when the level of anxiety decreased (p < 0.0001). It increased with increasing level of optimism (p < 0.006) in the model for all dimensions of SF36 except the Role Physical dimension. In this model, interaction between anxiety and optimism was significant for the Social Functioning dimension (p = 0.0021). Conclusions Optimism and trait anxiety appeared to be significantly correlated with HRQOL. Furthermore, an interaction existed between the trait anxiety and optimism for some dimensions of SF36. Contrary to optimism, it seems essential to evaluate trait anxiety in future studies about HRQOL, since it could represent a confounding factor. PMID:23914779

In Brazil, despite the growing use of SF-36 in different research environments, most of the psychometric evaluation of the translated questionnaire was from studies with samples of patients. The purpose of this paper is to examine if the Brazilian version of SF-36 satisfies scaling assumptions, reliability and validity required for valid interpretation of the SF-36 summated ratings scales in the general population. 12,423 individuals and their spouses living in 8,048 households were selected from a stratified sample of all permanent households along the country to be interviewed using the Brazilian SF-36 (version 2). Psychometric tests were performed to evaluate the scaling assumptions based on IQOLA methodology. Data quality was satisfactory with questionnaire completion rate of 100%. The ordering of the item means within scales clustered as hypothesized. All item-scale correlations exceeded the suggested criteria for reliability with success rate of 100% and low floor and ceiling effects. All scales reached the criteria for group comparison and factor analysis identified two principal components that jointly accounted for 67.5% of the total variance. Role emotional and vitality were strongly correlated with physical and mental components, respectively, while social functioning was moderately correlated with both components. Role physical and mental health scales were, respectively, the most valid measures of the physical and mental health component. In the comparisons between groups that differed by the presence or absence of depression, subjects who reported having the disease had lower mean scores in all scales and mental health scale discriminated best between the two groups. Among those healthy and with one, two or three and more chronic illness, the average scores were inverted related to the number of diseases. Body pain, general health and vitality were the most discriminating scales between healthy and diseased groups. Higher scores were associated with individuals of male sex, age below 40 years old and high schooling. The Brazilian version of SF-36 performed well and the findings suggested that it is a reliable and valid measure of health related quality of life among the general population as well as a promising measure for research on health inequalities in Brazil.

Context Human NR5A1/SF-1 mutations cause 46,XY disorder of sex development (DSD) with broad phenotypic variability, and rarely cause adrenal insufficiency although SF-1 is an important transcription factor for many genes involved in steroidogenesis. In addition, the Sf-1 knockout mouse develops obesity with age. Obesity might be mediated through Sf-1 regulating activity of brain-derived neurotrophic factor (BDNF), an important regulator of energy balance in the ventromedial hypothalamus. Objective To characterize novel SF-1 gene variants in 4 families, clinical, genetic and functional studies were performed with respect to steroidogenesis and energy balance. Patients 5 patients with 46,XY DSD were found to harbor NR5A1/SF-1 mutations including 2 novel variations. One patient harboring a novel mutation also suffered from adrenal insufficiency. Methods SF-1 mutations were studied in cell systems (HEK293, JEG3) for impact on transcription of genes involved in steroidogenesis (CYP11A1, CYP17A1, HSD3B2) and in energy balance (BDNF). BDNF regulation by SF-1 was studied by promoter assays (JEG3). Results Two novel NR5A1/SF-1 mutations (Glu7Stop, His408Profs*159) were confirmed. Glu7Stop is the 4th reported SF-1 mutation causing DSD and adrenal insufficiency. In vitro studies revealed that transcription of the BDNF gene is regulated by SF-1, and that mutant SF-1 decreased BDNF promoter activation (similar to steroid enzyme promoters). However, clinical data from 16 subjects carrying SF-1 mutations showed normal birth weight and BMI. Conclusions Glu7Stop and His408Profs*159 are novel SF-1 mutations identified in patients with 46,XY DSD and adrenal insufficiency (Glu7Stop). In vitro, SF-1 mutations affect not only steroidogenesis but also transcription of BDNF which is involved in energy balance. However, in contrast to mice, consequences on weight were not found in humans with SF-1 mutations. PMID:25122490

Abnormal Size-Dependent Modulation of Motion Perception in Children with Autism Spectrum Disorder (ASD).

Excitation/Inhibition (E/I) imbalance in neural networks is now considered among the core neural underpinnings of autism psychopathology. In motion perception at least two phenomena critically depend on E/I balance in visual cortex: spatial suppression (SS), and spatial facilitation (SF) corresponding to impoverished or improved motion perception with increasing stimuli size, respectively. While SS is dominant at high contrast, SF is evident for low contrast stimuli, due to the prevalence of inhibitory contextual modulations in the former, and excitatory ones in the latter case. Only one previous study (Foss-Feig et al., 2013) investigated SS and SF in Autism Spectrum Disorder (ASD). Our study aimed to replicate previous findings, and to explore the putative contribution of deficient inhibitory influences into an enhanced SF index in ASD-a cornerstone for interpretation proposed by Foss-Feig et al. (2013). The SS and SF were examined in 40 boys with ASD, broad spectrum of intellectual abilities (63 < IQ < 127) and 44 typically developing (TD) boys, aged 6-15 years. The stimuli of small (1°) and large (12°) radius were presented under high (100%) and low (1%) contrast conditions. Social Responsiveness Scale and Sensory Profile Questionnaire were used to assess the autism severity and sensory processing abnormalities. We found that the SS index was atypically reduced, while SF index abnormally enhanced in children with ASD. The presence of abnormally enhanced SF in children with ASD was the only consistent finding between our study and that of Foss-Feig et al. While the SS and SF indexes were strongly interrelated in TD participants, this correlation was absent in their peers with ASD. In addition, the SF index but not the SS index correlated with the severity of autism and the poor registration abilities. The pattern of results is partially consistent with the idea of hypofunctional inhibitory transmission in visual areas in ASD. Nonetheless, the absence of correlation between SF and SS indexes paired with a strong direct link between abnormally enhanced SF and autism symptoms in our ASD sample emphasizes the role of the enhanced excitatory influences by themselves in the observed abnormalities in low-level visual phenomena found in ASD.

For men with high-volume or high-grade prostate cancer, wide excision of the ipsilateral neurovascular bundle is commonly performed. The concept of nerve reconstruction is intriguing as a feasible approach to preserve sexual function (SF). We sought to evaluate the functional, pathologic, and oncologic outcomes of men who underwent robot-assisted sural-nerve graft (SNG) interposition. Between February 2003 and May 2007, 1175 consecutive men underwent robot-assisted laparoscopic radical prostatectomy (RLRP). Database analysis identified 27 men who had SNG: 4 bilateral (BL) and 23 unilateral (UL). SF was prospectively evaluated preoperatively and at 1, 3, 6, 12, and 24 months postoperatively using validated questionnaires. Positive surgical margins (PSMs), biochemical recurrence (BCR), and potency were evaluated. Compared with RLRP patients without SNG, patients with SNG were younger (57.2 v 61.8 years, P=0.02), had a higher Gleason score (P=0.02), and had a higher clinical and pathologic stage (P<0.001 for both). Mean surgical time was significantly longer (349 v 195 min, P<0.001) in patients with SNG. With a mean follow-up of 26.1 months, 11 (47.8%) patients with UL-SNG and zero men with BL-SNG regained potency. No significant difference in SF was observed between UL nerve sparing and no SNG (56%) compared with UL nerve sparing with UL-SNG (P=0.44). Rates of return-to-baseline SF (RTB-SF) at 6, 12, and 24 months were 11%, 36% and 45% for UL-SNG, respectively, which were also comparable to UL nerve sparing only (P>0.05). No patient (0%) in the BL-SNG group ever achieved RTB-SF status at any time point. PSMs were observed in 37% (10/27) of all patients. BCR occurred in nine patients (33.3%), seven of whom had PSM (78%); treatment failure occurred within 6 months of surgery, necessitating androgen deprivation therapy. Despite optimism regarding SNG, long-term functional outcomes have been disappointing, particularly for BL nerve interposition. UL-SNG functional outcomes do not appear to improve outcomes when compared with men with UL nerve preservation. With the greater risk of PSM and BCR in patients who are considered candidates for SNG, newer treatment modalities are needed to cure their disease while preserving SF.

We performed a review of the literature reporting on the effects of pelvic floor muscle training (PFMT) on female sexual function (SF). Pubmed (from 1946 to December 2014), Ovid Medline (from 1946 to December 2014), CINAHL (from 1937 to December 2014), PsycINFO (from 1805 to December 2014), Scopus and Cochrane Central Register of Controlled Trials were searched by two independent reviewers. Randomised controlled trials (RCTs) investigating the impact of PFMT on women's SF published in English were included. Methodological quality was scored using the PEDro scale. Data were analysed qualitatively and interpreted. A total of 1341 women were included in the eight RCTs covered by this review. The studies were published between 1997 and 2014. Methodological scores were between 4 and 7. The sample included derived from heterogeneous populations of women. In only one study was SF the primary outcome measure. Pelvic floor dysfunction was an inclusion criterion in the majority of studies. Most studies reported a significant improvement in SF score after PFMT between control and intervention groups. Although most studies indicated an improvement of at least one sexual variable in women with pelvic floor dysfunction, and one study demonstrated an improvement in SF in postpartum women selected independently of their continence status, the results need to be interpreted with caution. High-quality RCTs specifically designed to investigate the impact of PFMT on women's SF are required.

Inflammatory arthritis impairs participation in societal roles. Role overload arises when the demands by a given role set exceed the resources; time and energy, to carry out the required tasks. The present study examines the association between role overload and disease outcomes in early inflammatory arthritis (EIA). Patients (n = 104) of 7.61 months mean duration of inflammatory arthritis completed self-report questionnaires on sociodemographics, disease characteristics and role overload. Pain was assessed using the Short Form McGill Pain Questionnaire (MPQ) and physical functioning was measured with the Medical Outcomes Study Short Form 36 (SF-36) physical functioning score. Role overload was measured by the Role Overload Scale. Patients indicated the number of social roles they occupied from a total of the three typical roles; marital, parental and paid work. Participants' mean age was 56 years and 70.2% were female. Role overload was not correlated to the number of social roles, however, it was positively associated with pain (p = 0.004) and negatively associated with physical functioning (p = 0.001). On multivariate analysis, role overload was negatively associated with physical functioning after controlling for the relevant sociodemographic variables. This study identifies a possible reciprocal relationship between role overload and physical functioning in patients with EIA.

Stellar Content and Star Formation in Young Clusters Influenced by Massive Stars

Star Formation (SF) in extreme environment is always challenging and can be significantly different from that in quiet environments. This study presents the comprehensive multi-wavelength (optical, NIR, MIR and radio) observational analysis of three Galactic starforming regions associated with H II regions/young clusters and located at > 2 kpc, which are found to be evolving under the influence of massive stars within their vicinity. The candidate massive stars, young stellar objects, their mass, age, age spread, the form of K-band Luminosity Function (KLF), Initial Mass Function (IMF) and a possible formation history of each region are studied. The major results on Sh2-252, an extended H II region that appears to be undergoing multiple episodes of SF, are highlighted. Our analysis shows that all the regions are undergoing complex SF activity and the new generation of stars in each region seem to be an outcome of the influence by the presence of massive stars within them. SF process in these regions are likely to be multi-fold and the results suggest that multiple modes of triggering mechanism and hierarchial modes of SF are a common phenomena within young clusters.

Human equilibrative nucleoside transporter-1 (hENT1) is the major plasma membrane transporter involved in transportation of natural nucleosides as well as nucleoside analog drugs, used in anti-cancer and anti-viral therapies. Despite extensive biochemical and pharmacological studies, little is known about the structure-function relationship of this protein. The major obstacles to purification include a low endogenous expression level, the lack of an efficient expression and purification protocol, and the hydrophobic nature of the protein. Here, we report protein expression, purification and functional characterization of hENT1 from Sf9 insect cells. hENT1 expressed by Sf9 cells is functionally active as demonstrated by saturation binding with a Kd of 1.2±0.2nM and Bmax of 110±5pmol/mg for [(3)H]nitrobenzylmercaptopurine ribonucleoside ([(3)H]NBMPR). We also demonstrate purification of hENT1 using FLAG antibody affinity resin in lauryl maltose neopentyl glycol detergent with a Kd of 4.3±0.7nM. The yield of hENT1 from Sf9 cells was ∼0.5mg active transporter per liter of culture. The purified protein is functionally active, stable, homogenous and appropriate for further biophysical and structural studies. Copyright © 2015 Elsevier Inc. All rights reserved.

Cohort study. To evaluate the responsiveness of common pain and disability measures in a cohort of patients with chronic whiplash. Pain and disability are routinely measured in clinical practice and clinical research. However, to date, a head-to-head comparison of competing measures for whiplash patients has not been performed. Pain (pain intensity, bothersomeness, and SF-36 bodily pain score) and disability (Patient Specific Functional Scale, Neck Disability Index, Functional Rating Index, Copenhagen Scale, and SF-36 physical summary) measures were completed by 132 patients with chronic whiplash at baseline and then again after 6 weeks together with an 11-point global perceived effect scale. Internal responsiveness was evaluated by calculating effect sizes and standardized response means, and external responsiveness by correlating change scores with global perceived effect scores and by ROC curves. The ranking of responsiveness was consistent across the different analyses. Pain bothersomeness was more responsive than pain intensity, which was more responsive than the SF-36 pain measure. The Patient Specific Functional Scale was the most responsive disability measure, followed by the spine-specific measures, with the SF-36 physical summary measure the least responsive. Pain bothersomeness and the Patient Specific Functional Scale provide the most responsive measures of pain and disability, respectively, in patients with chronic whiplash.

This study investigates the effect of gender role and the psychosocial work environment on the psychological well-being of hospital staff in two general hospitals in the province of Valencia (Spain). A cross-sectional survey was carried out among 313 workers by means of a self-answered questionnaire. The outcome variable (psychological well-being) was evaluated with four dimensions of the "SF-36 Health Survey" (mental health, vitality, limitations in the emotional role and limitations in the social function). The explanatory variables were: characteristics related to gender role, professional characteristics and the psychosocial working environment evaluated according to Karasek and Johnson's demand-control-support model. The adjusted odds ratios (ORs) and their 95% confidence intervals were calculated by logistical regression. Those who have very good marital relationship have less risk of presenting bad mental health, OR 0.43 (0.24-0.78), and limitation in the social function, OR 0.43 (0.24-0.77), and in the emotional role, OR 0.35 (0.16-0.74). Those who dedicate more than 30 h a week to domestic chores have a higher risk of limitation of social function, OR 2.48 (1.16-5.31). Those exposed to high psychological demands present a higher probability of having bad mental health, OR 1.77 (1.04-3.00). Those exposed to low job social support have a higher risk of bad mental health, OR 1.86 (1.09-3.19), low vitality, OR 2.21 (1.30-3.77), and limitation in the social function, OR 1.88 (1.10-3.22). Gender role and psychosocial work environment have a negative influence on the psychological well-being of hospital staff.

In most types of cancer, the disease and its treatment can result in altered sexual function (SF). Oncology nurses are strategically placed to address SF since they have frequent patient interaction. Our aim was to establish their knowledge about and attitudes to SF in oncology care and identify their perceived barriers to addressing the subject. A 37-item questionnaire was administered during the 2012 Dutch Oncology Nursing Congress and mailed to 241 Dutch oncology nursing departments. The majority of 477 nurses (87.6%) agreed that discussing SF is their responsibility. Discussing SF routinely is performed by 33.4% of these nurses, consultations mainly consisted of mentioning treatment side-effects affecting SF (71.3%). There were significant differences depending on experience, knowledge, age, academic degree and department policy. Nurses ≤44 years old (p < 0.001), with <10 years oncology experience (p = 0.001), insufficient knowledge (p < 0.001), no academic degree (p < 0.001), and in whose department policy was lacking or inadequate (p < 0.001), were less comfortable discussing SF. Barriers included lack of training, presence of a third party and no angle or motive for initiating discussion. Findings suggest oncology nurses consider counselling on sexual issues to be an important responsibility, in line with discussing other side-effects caused by the disease or its treatment. Nevertheless, cancer patients may not routinely be receiving a sexual health evaluation by oncology nurses. Results emphasize the potential benefit of providing knowledge, including practical training and a complete department protocol. Copyright © 2015 Elsevier Ltd. All rights reserved.

OBJECTIVE The object of this study was to determine the percentage of high-dose (1800-2600 cGy) single-fraction stereotactic radiosurgery (SF-SRS) treatments to the spine that result in peripheral nervous system (PNS) injury. METHODS All patients treated with SF-SRS for primary or metastatic spine tumors between January 2004 and May 2013 and referred to the Rehabilitation Medicine Service for evaluation and treatment of neuromuscular, musculoskeletal, or functional impairments or pain were retrospectively identified. RESULTS Five hundred fifty-seven SF-SRS treatments in 447 patients resulted in 14 PNS injuries in 13 patients. All injures resulted from SF-SRS delivered to the cervical or lumbosacral spine at 2400 cGy. The overall percentage of SF-SRS treatments resulting in PNS injury was 2.5%, increasing to 4.5% when the thoracic spine was excluded from analysis. The median time to symptom onset following SF-SRS was 10 months (range 4-32 months). The plexus (cervical, brachial, and/or lumbosacral) was affected clinically and/or electrophysiologically in 12 (86%) of 14 cases, the nerve root in 2 (14%) of 14, and both in 6 (43%) of 14 cases. All patients experienced pain and most (93%) developed weakness. Peripheral nervous system injuries were CTCAE Grade 1 in 14% of cases, 2 in 64%, and 3 in 21%. No dose relationship between SF-SRS dose and PNS injury was detected. CONCLUSIONS Single-fraction SRS to the spine can result in PNS injury with major implications for function and quality of life.

Infection with Autographa californica multiple nucleopolyhedrovirus (AcMNPV) mutants lacking a functional p35 gene can induce host cell apoptosis, which provides the possibility to use the potential of these viruses in the biological control of pest insects. Nonetheless, the proteomics or the protein changes of Spodoptera frugiperda (Sf9) cells infected with p35 knockout AcMNPV have not yet been studied. To further improve the use of AcMNPV, we set out to analyze the protein composition and protein changes of Sf9 cells of different infection stages by isobaric tag for relative and absolute quantification (iTRAQ) techniques. A total of 4004 sf9 proteins were identified by iTRAQ. After comparation of the significantly expressed 483 proteins from p35koAcMNPV-infected Sf9 cells and the significantly expressed 413 proteins from wtAcMNPV-infected Sf9 cells, we found that 226 proteins were specific to p35koAcMNPV-infected Sf9 cells. The 226 proteins were categorized according to GO classification for insects and were categorized into: biological processes, molecular functions and cellular components. Of interest, the most up-regulated proteins related to Epstein-Barr virus infection, RNA transport, Calcium signaling pathway, cGMP-PKG signaling pathway, oxidative phosphorylation and N-Glycan biosynthesis. Determination of the protein changes in p35 knockout AcMNPV-infected Sf9 cells would facilitate the better use of this virus-host cell interaction in pest insect control and other related fields.

The Social Role Participation Questionnaire (SRPQ) assesses the influence of health on 11 specific roles and 1 general role along 4 dimensions. In this study, a shortened version of the SRPQ (s-SRPQ) was developed in patients with ankylosing spondylitis (AS) to facilitate data collection in clinical studies and practice. Using data from 246 patients with AS and population controls, the fit of each role to the different participation dimensions, the contribution of each role to the measurement precision, and the correlation between dimensions were evaluated using item response theory. Representation of the 3 participation chapters of the International Classification of Functioning, Disability, and Health was ensured. Reliability of each dimension of both versions of the SRPQ was compared by correlating scores to the Medical Outcomes Study Short Form-36 (SF-36) and the Satisfaction With Life Scale (SWLS), and by comparing ability to discriminate between patients and controls and between patients with low and high disease activity (Bath Ankylosing Spondylitis Disease Activity Index ≥ 4). The s-SRPQ, which assesses participation across 6 social roles along 2 dimensions (physical difficulty and satisfaction with performance), was proposed. Both dimensions of the s-SRPQ were highly reliable (r ≥ 0.86) and were shown to have construct validity as indicated by a similar pattern of correlations with the SF-36 and SWLS as the original SRPQ dimensions. Both versions discriminated well between patients and controls and between patients with high versus low disease activity (relative validity ≥ 0.72). The s-SRPQ retains the measurement properties of the original SRPQ and seems useful for measuring the effect of AS on participation.

The objective of this study is to assess the quality of life (QOL) of cancer patients and their family members over 1-year period post therapy. We evaluated QOL in cancer patients (N = 161) (Short Form-8 Health Survey (SF-8), European Organization for Research and Treatment of Cancer 30- Item Core Quality of Life Questionnaire (EORTC QLQ-C30)), their partners (N = 110) (SF-8), and their children (N = 115) (KIDSCREEN-27) using a longitudinal design (t1: post therapy, t2: 6 months after t1, t3: 12 months after t1). Multiple regression models were employed to examine factors related to QOL. After cancer therapy, impairments in the patients' QOL were found primarily in emotional and social areas and also in role functions. We found the highest symptom burden in fatigue (M = 45.21), sleep disturbances (M = 41.04), and financial difficulties (M = 39.2). Partners had lower mental QOL compared with the general population at each assessment point (p < 0.05). No significant difference was found in physical QOL between partners and the general population (p > 0.05). Social support, full-time employment, tumor stage 0-2, time since diagnosis <1 year, and lower levels of anxiety and depression were associated with better QOL in patients. Full-time employment, social support, and lower levels of anxiety and depression had a significant impact on the partners' QOL. Higher levels of anxiety and depression in patients (p = 0.006) adversely influenced children's QOL. Family members' QOL is overall stable over time indicating the need for professional psychosocial support for those family members with low QOL. For the children, new measures are needed to better examine the experience with parental cancer. Copyright © 2014 John Wiley & Sons, Ltd.

Functional evaluation of upper limb is not only based on clinical findings but requires self-administered questionnaires to address patients' perspective. The Hand Function Sort (HFS©) was only validated in English. The aim of this study was the French cross cultural adaptation and validation of the HFS© (HFS-F). 150 patients with various upper limbs impairments were recruited in a rehabilitation center. Translation and cross-cultural adaptation were made according to international guidelines. Construct validity was estimated through correlations with Disabilities Arm Shoulder and Hand (DASH) questionnaire, SF-36 mental component summary (MCS),SF-36 physical component summary (PCS) and pain intensity. Internal consistency was assessed by Cronbach's α and test-retest reliability by intraclass correlation. Cronbach's α was 0.98, test-retest reliability was excellent at 0.921 (95 % CI 0.871-0.971) same as original HFS©. Correlations with DASH were-0.779 (95 % CI -0.847 to -0.685); with SF 36 PCS 0.452 (95 % CI 0.276-0.599); with pain -0.247 (95 % CI -0.429 to -0.041); with SF 36 MCS 0.242 (95 % CI 0.042-0.422). There were no floor or ceiling effects. The HFS-F has the same good psychometric properties as the original HFS© (internal consistency, test retest reliability, convergent validity with DASH, divergent validity with SF-36 MCS, and no floor or ceiling effects). The convergent validity with SF-36 PCS was poor; we found no correlation with pain. The HFS-F could be used with confidence in a population of working patients. Other studies are necessary to study its psychometric properties in other populations.

The aim of this study was to analyze the correlation of vitamin D levels with clinical parameters, bone mineral density (BMD), quality of life (QoL) and nailfold capillaroscopy (NC) in patients with diffuse systemic sclerosis (SSc). Thirty-eight female patients with diffuse SSc were analyzed regarding 25-hydroxyvitamin D (25OHD) serum levels. At inclusion, organ involvement, autoantibodies, modified Rodnan skin score (mRSS), Medsger Disease Severity Index (MDSI), body mass index (BMI), BMD, NC, Short-Form-36 Questionnaire (SF-36), and Health Assessment Questionnaire (HAQ), were performed through a standardized interview, physical examination and electronic chart review. Mean 25OHD serum level was 20.66±8.20ng/mL. Eleven percent of the patients had 25OHD levels ≤10ng/mL, 50% ≤20ng/mL and 87% ≤30ng/mL. Vitamin D serum levels were positively correlated with BMI (r=0.338, p=0.038), BMD-total femur (r=0.340, p=0.037), BMD-femoral neck (r=0.384, p=0.017), SF-36-Vitality (r=0.385, p=0.017), SF-36-Social Function (r=0.320, p=0.050), SF-36-Emotional Role (r=0.321, p=0.049) and SF-36-Mental Health (r=0.531, p=0.0006) and were negatively correlated with HAQ-Reach (r=-0.328, p=0.044) and HAQ-Grip Strength (r=-0.331, p=0.042). A negative correlation with NC-diffuse devascularization (p=0.029) and NC-avascular area (p=0.033) was also observed. The present study provides novel evidence demonstrating that low levels of 25OHD have a negative impact in diffuse SSc QoL and further studies are needed to define whether vitamin D supplementation can improve health related QoL in these patients. The additional observation of a correlation with severe NC alterations suggests a possible role of 25OHD in the underlying SSc vascular involvement. Copyright © 2016 Elsevier Editora Ltda.

Although social franchising has been shown to enhance the quality of reproductive health services in developing countries, its effect on nutrition services remains unexamined. This study assessed the effects of incorporating elements of social franchising on shaping the quality of infant and young child feeding (IYCF) counselling facilities and services in Vietnam. Process-related data collected 12 months after the launch of the first franchises were used to compare randomly assigned Alive & Thrive-supported health facilities (AT-F, n = 20) with standard facilities (SF, n = 12) across three dimensions of service quality: 'structure', 'process' and 'outcome' that capture the quality of facilities, service delivery, and client perceptions and use, respectively. Data collection included facility assessments (n = 32), staff surveys (n = 96), counselling observations (n = 137), client exit interviews (n = 137) and in-depth interviews with mothers (n = 48). Structure: AT-F were more likely to have an unshared, well-equipped room for nutrition counselling than SF (65.0% vs 10.0%). Compared with SF providers, AT-F staff had better IYCF knowledge (mean score 9.9 vs 8.8, range 0-11 for breastfeeding; mean score 3.6 vs 3.2, range 0-4 for complementary feeding). AT-F providers also demonstrated significantly better interpersonal communication skills (score 9.6 vs 5.1, range 0-13) and offered more comprehensive counselling sessions. Overall utilization of franchises was low (10%). A higher proportion of pregnant women utilized franchise services (48.9%), compared with mothers with children 6-23.9 months (1.4%). There was no quantitative difference in client satisfaction with counselling services between AT-F and SF, but franchise users praised the AT-F for problem solving related to child feeding. Incorporating elements of social franchising significantly enhances the quality of IYCF counselling services within government primary healthcare facilities, particularly their structural and process attributes. Provided that service utilization is improved through demand generation, this model has the potential to impact IYCF practices and child nutrition.

In the era of life-prolonging antiretroviral therapy, chronic fatigue is one of the most prevalent and disabling symptoms of people living with HIV/AIDS, yet its measurement remains challenging. No instruments have been developed specifically to describe HIV-related fatigue. We assessed the reliability and construct validity of the HIV-Related Fatigue Scale (HRFS), a 56-item self-report instrument developed through formative qualitative research and designed to measure the intensity and consequences of fatigue as well as the circumstances surrounding fatigue in people living with HIV. The HRFS has three main scales, which measure fatigue intensity, the responsiveness of fatigue to circumstances and fatigue-related impairment of functioning. The functioning scale can be further divided into subscales measuring impairment of activities of daily living, impairment of mental functioning and impairment of social functioning. Each scale demonstrated high internal consistency (Cronbach’s alpha=0.93, 0.91 and 0.97 for the intensity, responsiveness and functioning scales, respectively). The HRFS scales also demonstrated satisfactory convergent validity when compared to other fatigue measures. HIV-Related Fatigue Scales were moderately correlated with quality of nighttime sleep (rho = 0.46, 0.47 and 0.35) but showed only weak correlations with daytime sleepiness (rho = 0.20, 0.33 and 0.18). The scales were also moderately correlated with general mental and physical health as measured by the SF-36 Health Survey (rho ranged from 0.30 to 0.68 across the 8 SF-36 subscales with most >0.40). The HRFS is a promising tool to help facilitate research on the prevalence, etiology and consequences of fatigue in people living with HIV. PMID:18608084

A number of ergonomic, workplace and individual psychosocial factors and health behaviors have been associated with the onset, exacerbation and/or maintenance of low back pain (LBP). The functional impact of these factors may be influenced by how a worker approaches problems in general. The present study was conducted to determine whether problem-solving orientation was associated with physical and mental health outcomes in fully employed workers (soldiers) reporting a history of LBP in the past year. The sample consisted of 475 soldiers (446 male, 29 female; mean age 24.5 years) who worked in jobs identified as high risk for LBP-related disability and reported LBP symptoms in the past 12 months. The Social Problem-Solving Inventory and the Standard Form-12 (SF-12) were completed by all subjects. Hierarchical multiple regression analyses were used to predict the SF-12 physical health summary scale from interactions of LBP symptoms with each of five problem-solving subscales. Low scores on positive problem-solving orientation (F(1,457)=4.49), and high scores on impulsivity/carelessness (F(1,457)=9.11) were associated with a steeper gradient in functional loss related to LBP. Among those with a longer history of low-grade LBP, an avoidant approach to problem-solving was also associated with a steeper gradient of functional loss (three-way interaction; F(1,458)=4.58). These results suggest that the prolonged impact of LBP on daily function may be reduced by assisting affected workers to conceptualize LBP as a problem that can be overcome and using strategies that promote taking an active role in reducing risks for LBP. Secondary prevention efforts may be improved by addressing these factors.

Population aging is escalating in numerous countries worldwide; among them is Taiwan, which will soon become an aged society. Thus, aging successfully is an increasing concern. One of the factors for achieving successful aging (SA) is maintaining high physical function. The purpose of this study was to determine the physical fitness factors associated with SA in Taiwanese older adults (OAs), because these factors are intervenable. Community-dwelling OAs aged more than 65 years and residing in Northern Taiwan were recruited in this study. They received a comprehensive geriatric assessment, which includes sociodemographic data, health conditions and behaviors, activities of daily living (ADL) and instrumental ADL (IADL) function, cognitive and depressive status, and quality of life. Physical fitness tests included the grip strength (GS), 30-second sit-to-stand (30s STS), timed up-and-go (TUG), functional reach (FR), one-leg standing, chair sit-and-reach, and reaction time (drop ruler) tests as well as the 6-minute walk test (6MWT). SA status was defined as follows: complete independence in performing ADL and IADL, satisfactory cognitive status (Mini-Mental State Examination ≥ 24), no depression (Geriatric Depression Scale < 5), and favorable social function (SF subscale ≥ 80 in SF-36). Adjusted multiple logistic regression analyses were performed. Among the total recruited OAs (n = 378), 100 (26.5%) met the aforementioned SA criteria. After adjustment for sociodemographic characteristics and health condition and behaviors, some physical fitness tests, namely GS, 30s STS, 6MWT, TUG, and FR tests, were significantly associated with SA individually, but not in the multivariate model. Among the physical fitness variables tested, cardiopulmonary endurance, mobility, muscle strength, and balance were significantly associated with SA in Taiwanese OAs. Early detection of deterioration in the identified functions and corresponding intervention is essential to ensuring SA.

Survival prospects for adults with repaired tetralogy of Fallot (TOF) are now excellent. Attention should therefore shift to assessing and improving functional health status and quality of life. We aimed to assess late functional health status of adults surviving TOF repair by matched comparison to their healthy siblings. All 1,693 TOF repairs performed at our institution between 1946 and 1990 were reviewed. A matched comparison was undertaken whereby presumed survivors and their healthy sibling were contacted and asked to complete the Ontario Health Survey 1990 and the 36-Item Short Form Health Survey (SF-36) questionnaire. Both questionnaires were completed by 224 adult survivors and their sibling closest in age. Adults with repaired TOF had lower scores for self-perceived general health status (p < 0.001), were less likely to rate their health as good or excellent (p < 0.001), and had lower SF-36 scores for physical functioning and general health (p = 0.001) than their siblings. However, patients reported similar satisfaction with their lives, similar levels of social participation and support, and were as likely to be in long-term partnerships. Worse physical and mental health scores were associated with older age at surgery and at time of questionnaire completion and recent requirement for noncardiac medication. Although reporting lower functional health status then their siblings, quality of life and life satisfaction for adults who underwent surgery for TOF during childhood is comparable to that of their siblings without heart defects. Follow-up of younger adults is required to understand current health outcomes attributable to improvements in the management of TOF. Copyright © 2012 The Society of Thoracic Surgeons.

Dating groundwater with trifluoromethyl sulfurpentafluoride (SF 5CF3), sulfur hexafluoride (SF6), CF 3Cl (CFC-13), and CF2Cl2 (CFC-12)

2008-01-01

[1] A new groundwater dating procedure using the transient atmospheric signal of the environmental tracers SF5CF3, CFC-13, SF6, and CFC-12 was developed. The analytical procedure determines concentrations of the four tracers in air and water samples. SF 5CF3 and CFC-13 can be used to date groundwaters in some environments where the CFCs and SF6 have previously failed because these new tracers have increasing atmospheric input functions, no known terrigenic source, and are believed to be stable under reducing conditions. SF5CF3 has a dating range from 1970 to modern; the mixing ratio (mole fraction) in North American air has increased from the detection limit of 0.005 parts per trillion (ppt) to the 2006 mole fraction of about 0.16 ppt. No evidence was found for degradation of SF5CF3 in laboratory anaerobic systems. The solubility of SF5CF3 was measured in water from 1 to 35??C. Groundwater samples that contained large amounts of terrigenic SF6 did not contain terrigenic SF 5CF3. CFC-13 is a trace atmospheric gas with a dating range in groundwater of about 1965 to modem. CFC-13 has been used primarily in very low-temperature refrigeration; thus groundwater environments are less likely to be contaminated with nonatmospheric sources as compared to other widely used CFCs. Because of the low solubility of SF5CF3 and CFC-13 in water, an excess air correction must be applied to the apparent ages. The new dating procedure was tested in water samples from wells and springs from Maryland, Virginia, and West Virginia.

Correlations between Transmembrane 4 L6 Family Member 5 (TM4SF5), CD151, and CD63 in Liver Fibrotic Phenotypes and Hepatic Migration and Invasive Capacities

Transmembrane 4 L6 family member 5 (TM4SF5) is overexpressed during CCl4-mediated murine liver fibrosis and in human hepatocellular carcinomas. The tetraspanins form tetraspanin-enriched microdomains (TEMs) consisting of large membrane protein complexes on the cell surface. Thus, TM4SF5 may be involved in the signal coordination that controls liver malignancy. We investigated the relationship between TM4SF5-positive TEMs with liver fibrosis and tumorigenesis, using normal Chang hepatocytes that lack TM4SF5 expression and chronically TGFβ1-treated Chang cells that express TM4SF5. TM4SF5 expression is positively correlated with tumorigenic CD151 expression, but is negatively correlated with tumor-suppressive CD63 expression in mouse fibrotic and human hepatic carcinoma tissues, indicating cooperative roles of the tetraspanins in liver malignancies. Although CD151 did not control the expression of TM4SF5, TM4SF5 appeared to control the expression levels of CD151 and CD63. TM4SF5 interacted with CD151, and caused the internalization of CD63 from the cell surface into late lysosomal membranes, presumably leading to terminating the tumor-suppressive functions of CD63. TM4SF5 could overcome the tumorigenic effects of CD151, especially cell migration and extracellular matrix (ECM)-degradation. Taken together, TM4SF5 appears to play a role in liver malignancy by controlling the levels of tetraspanins on the cell surface, and could provide a promising therapeutic target for the treatment of liver malignancies.

The signaling phospholipid PIP 3 creates a new interaction surface on the nuclear receptor SF-1

DOE PAGES

Blind, Raymond D.; Sablin, Elena P.; Kuchenbecker, Kristopher M.; ...

2014-10-06

We previously reported that lipids PI(4,5)P 2 (PIP 2) and PI(3,4,5)P 3 (PIP 3) bind NR5A nuclear receptors to regulate their activity. Here, the crystal structures of PIP 2 and PIP 3 bound to NR5A1 (SF-1) define a new interaction surface that is organized by the solvent-exposed PIPn headgroups. We find that stabilization by the PIP 3 ligand propagates a signal that increases coactivator recruitment to SF-1, consistent with our earlier work showing that PIP 3 increases SF-1 activity. This newly created surface harbors a cluster of human mutations that lead to endocrine disorders, thus explaining how these puzzling mutationsmore » cripple SF-1 activity. Finally, we propose that this new surface acts as a PIP 3-regulated interface between SF-1 and coregulatory proteins, analogous to the function of membrane-bound phosphoinositides.« less

The purpose of this investigation was to assess muscle fiber size, composition, and in vivo contractile characteristics of the calf muscle of four male crew members during a 17-day spaceflight (SF; Life and Microgravity Sciences Spacelab Shuttle Transport System-78 mission) and eight men during a 17-day bed rest (BR). The protocols and timelines of these two investigations were identical, therefore allowing for direct comparisons between SF and the BR. The subjects' age, height, and weight were 43 +/- 2 yr, 183 +/- 4 cm, and 86 +/- 3 kg for SF and 43 +/- 2 yr, 182 +/- 3 cm, and 82 +/- 4 kg for BR, respectively. Calf muscle strength was examined before SF and BR; on days 2, 8, and 12 during SF and BR; and on days 2 and 8 of recovery. Muscle biopsies were obtained before and within 3 h after SF (gastrocnemius and soleus) and BR (soleus) before reloading. Maximal isometric calf strength and the force-velocity characteristics were unchanged with SF or BR. Additionally, neither SF nor BR had any effect on fiber composition or fiber size of the calf muscles studied. In summary, no changes in calf muscle strength and morphology were observed after the 17-day SF and BR. Because muscle strength is lost during unloading, both during spaceflight and on the ground, these data suggest that the testing sequence employed during the SF and BR may have served as a resistance training countermeasure to attenuate whole muscle strength loss.

Silk fibroin (SF) from Bombyx mori has received increasing interest in biomedical fields, because of its slow biodegradability, good biocompatibility, and low immunogenicity. Although SF-based hydrogels have been studied intensively as a potential matrix for tissue engineering, weak gelation performance and low mechanical strength are major limitations that hamper their widespread applicability. Therefore, searching for new strategies to improve the SF gelation property is highly desirable in tissue engineering research. Herein, we report a facile approach to induce rapid gelation of SF by a small peptide gelator (e.g., NapFF). Following the simple mixing of SF and NapFF in water, a stable hydrogel of SF was obtained in a short time period at physiological pH, and the minimum gelation concentration of SF can reach as low as 0.1%. In this process of gelation, NapFF not only can behave itself as a gelator for supramolecular self-assembly, but also can trigger the conformational transition of the SF molecule from random coil to β-sheet structure via hydrophobic and hydrogen-bonding interactions. More importantly, for the generation of a scaffold with favorable cell-surface interactions, a new peptide gelator (NapFFRGD) with Arg-Gly-Asp (RGD) domain was applied to functionalize SF hydrogel with improved bioactivity for cell adhesion and growth. Following encapsulating the vascular endothelial growth factor (VEGF), the SF gel was subcutaneously injected in mice, and served as an effective matrix to trigger the generation of new blood capillaries in vivo.

Background Patients with depressive disorders have limitations in physical and emotional functioning comparable to patients with chronic medical conditions. Personality disorders (PDs) are also known to be associated with functional impairment. Aims To determine the effects of PDs on the functioning and well-being of patients with major depressive disorder (MDD). Method In the Collaborative Longitudinal Personality Disorders Study, 668 patients who met criteria for schizotypal, borderline, avoidant, or obsessive-compulsive PDs or for MDD and no PD were assessed with semi-structured interviews at baseline, 6, 12, 24, and 36 months. In this study, 151 patients who met criteria for current MDD at the 36-month follow-up were compared on the basis of the presence (n = 118) or absence (n = 33) of persistent PD. Physical and social/emotional functioning and well-being were assessed using the Medical Outcomes Study (MOS) Short-Form Health Survey (SF-36). These results were compared with those of a sample of patients with MDD seen in the mental health specialty sector who were followed in the Medical Outcomes Study. Results Patients with MDD and co-occurring PD had significantly more impairment on scales measuring role limitations due to emotional problems, social functioning, and general health perceptions than patients with MDD and no PD. Although patients with MDD and no PD were found to have levels of functioning and well-being that were lower in several domains than those previously reported in depressed patients recruited from mental health settings, patients with MDD and co-occurring PD were found to have much lower levels of functioning in all areas than reported samples. Conclusions Co-occurring PDs contribute significantly to impairment in social and emotional functioning and reduced well-being in patients with MDD. PMID:16304504

The sampling and analytical methods are described more fully in Sturges et al. (2000). In summary, air samples were pumped from consolidated deep snow (firn) at Dome Concordia (eastern Antarctica) in December 1998 and January 1999, from the surface to a depth of approximately 100 m. Air samples were analyzed with a gas chromatograph - mass spectrometer, with a detection limit of about 0.001 parts per trillion (ppt). A diffusive transport model was used to calculate the age of samples as a function of depth. Measurements of SF6 were used to determine the mean age of the firn air by comparison with extrapolated measurements from Cape Grim, Tasmania combined with estimates from industrial emissions (Maiss and Brenninkmeijer 1998, adapted by Sturges et al. 2000). Dates for SF5CF3 are different than for SF6 due to the lower diffusivity of SF5CF3: the SF6 ages were multiplied by the ratio of the free-air diffusion coefficient of SF5CF3 to that of SF6 (1.18). Free-air diffusion coefficients were determined by a semi-empirical formula based on molecular volumes (Fuller et al. 1966). Note that mean ages represent a very wide distribution of probable ages spanning many years, with an increasing spread of ages at increasing depth

Steroidogenic Factor-1 and Human Disease

Steroidogenic factor-1 (SF-1) (Ad4BP, NR5A1) is a nuclear receptor that plays a key role in adrenal and reproductive development and function. Deletion of the gene encoding Sf-1 (Nr5a1) in mice results in severe developmental defects of the adrenal gland and gonad. Consequently, initial work on the potential effects of SF-1 disruption in humans focused on individuals with primary adrenal failure, a 46,XY karyotype, complete gonadal dysgenesis, and Müllerian structures. This is a rare phenotype, but has been reported on two occasions, because of alterations that affect key DNA-binding domains of SF-1. Attention then turned to a potential wider role of SF-1 in human adrenal and reproductive disorders. Although changes in SF-1 only very rarely cause isolated adrenal failure, it is emerging that variations in SF-1 are a surprisingly frequent cause of reproductive dysfunction in humans. In 46,XY disorders of sex development, a spectrum of phenotypes has been reported including severe and partial forms of gonadal (testicular) dysgenesis, hypospadias, anorchia with microphallus, and even male factor infertility. In 46,XX females, alterations in SF-1 are associated with primary ovarian insufficiency. Thus, SF-1 seems be a more significant factor in human reproductive health than was first envisioned, with implications for adults as well as children. PMID:23044873

This study aims to examine the subjective functional outcomes of patients 70 years or older who sustained distal radius fractures through the use of the Disability of the Arm, Shoulder, and Hand (DASH) and Short Form-8 Health (SF-8) surveys. Patients at least 70 years old with a distal radius fracture between 2000 and 2004 were identified and their charts reviewed. They were contacted to answer the DASH and SF-8 surveys. The radiographic injury parameters examined were articular stepoff greater than 2 mm, dorsal tilt on the lateral radiograph, ulnar variance, and presence of an ulnar styloid fracture. Fifty-eight patients answered the DASH and SF-8 surveys. The mean age at the time of injury in the survey group was 78 years old (range 70-94 years). Mean follow-up period was 33 months (range 13-65 months). Average DASH and SF-8 scores were 22.3 (SD 22.4) and 31.5 (SD 6.9), respectively. DASH scores were inversely correlated with SF-8 scores (R = -0.65, p < 0.01). Patients who sustained an associated ulnar styloid fracture demonstrated worse DASH scores than those without an ulnar styloid fracture (presence of ulnar styloid fracture: mean DASH 26.2, no ulnar styloid fracture: mean DASH 12.9, p = 0.04). There were no significant differences in functional outcome for any other radiographic parameters assessed. Males had statistically better DASH scores than the females (males: mean DASH 6.9, females: mean DASH 24.4, p = 0.003). No difference was found in functional outcome scores among different treatment groups. In elderly patients with distal radius fractures, the only radiographic parameter we found that affects functional outcome is an associated ulnar styloid fracture. Additionally, females had worse functional outcomes than males.

A comparison of the sensitivity of EQ-5D, SF-6D and TTO utility values to changes in vision and perceived visual function in patients with primary open-angle glaucoma

PubMed Central

2012-01-01

Background Economic viability of treatments for primary open-angle glaucoma (POAG) should be assessed objectively to prioritise health care interventions. This study aims to identify the methods for eliciting utility values (UVs) most sensitive to differences in visual field and visual functioning in patients with POAG. As a secondary objective, the dimensions of generic health-related and vision-related quality of life most affected by progressive vision loss will be identified. Methods A total of 132 POAG patients were recruited. Three sets of utility values (EuroQoL EQ-5D, Short Form SF-6D, Time Trade Off) and a measure of perceived visual functioning from the National Eye Institute Visual Function Questionnaire (VFQ-25) were elicited during face-to-face interviews. The sensitivity of UVs to differences in the binocular visual field, visual acuity and visual functioning measures was analysed using non-parametric statistical methods. Results Median utilities were similar across Integrated Visual Field score quartiles for EQ-5D (P = 0.08) whereas SF-6D and Time-Trade-Off UVs significantly decreased (p = 0.01 and p = 0.001, respectively). The VFQ-25 score varied across Integrated Visual Field and binocular visual acuity groups and was associated with all three UVs (P ≤ 0.001); most of its vision-specific sub-scales were associated with the vision markers. The most affected dimension was driving. A relationship with vision markers was found for the physical component of SF-36 and not for any dimension of EQ-5D. Conclusions The Time-Trade-Off was more sensitive than EQ-5D and SF-6D to changes in vision and visual functioning associated with glaucoma progression but could not measure quality of life changes in the mildest disease stages.

A putative novel rhabdovirus (SfRV) was previously identified in a Spodoptera frugiperda cell line (Sf9 cells [ATCC CRL-1711 lot 58078522]) by next generation sequencing and extensive bioinformatic analysis. We performed an extensive analysis of our Sf9 cell bank (ATCC CRL-1711 lot 5814 [Sf9L5814]) to determine whether this virus was already present in cells obtained from ATCC in 1987. Inverse PCR of DNA isolated from Sf9 L5814 cellular DNA revealed integration of SfRV sequences in the cellular genome. RT-PCR of total RNA showed a deletion of 320 nucleotides in the SfRV RNA that includes the transcriptional motifs for genes X and L. Concentrated cell culture supernatant was analyzed by sucrose density gradient centrifugation and revealed a single band at a density of 1.14 g/ml. This fraction was further analysed by electron microscopy and showed amorphous and particulate debris that did not resemble a rhabdovirus in morphology or size. SDS-PAGE analysis confirmed that the protein composition did not contain the typical five rhabdovirus structural proteins and LC-MS/MS analysis revealed primarily of exosomal marker proteins, the SfRV N protein, and truncated forms of SfRV N, P, and G proteins. The SfRV L gene fragment RNA sequence was recovered from the supernatant after ultracentrifugation of the 1.14 g/ml fraction treated with diethyl ether suggesting that the SfRV L gene fragment sequence is not associated with a diethyl ether resistant nucleocapsid. Interestingly, the 1.14 g/ml fraction was able to transfer baculovirus DNA into Sf9L5814 cells, consistent with the presence of functional exosomes. Our results demonstrate the absence of viral particles in ATCC CRL-1711 lot 5814 Sf9 cells in contrast to a previous study that suggested the presence of infectious rhabdoviral particles in Sf9 cells from a different lot. This study highlights how cell lines with different lineages may present different virosomes and therefore no general conclusions can be drawn across Sf9 cells from different laboratories.

This study aimed at validating an existing health-related quality of life questionnaire for patients with facial palsy for implementation in the Dutch language and culture. The Facial Clinimetric Evaluation Scale was translated into the Dutch language using a forward-backward translation method. A pilot test with the translated questionnaire was performed in 10 patients with facial palsy and 10 normal subjects. Finally, cross-cultural adaption was accomplished at our outpatient clinic for facial palsy. Analyses for internal consistency, test-retest reliability, construct validity and responsiveness were performed. Ninety-three patients completed the Dutch Facial Clinimetric Evaluation Scale, the Dutch Facial Disability Index, and the Dutch Short Form (36) Health Survey. Cronbach's α, representing internal consistency, was 0.800. Test-retest reliability was shown by an intraclass correlation coefficient of 0.737. Correlations with the House-Brackmann score, Sunnybrook score, Facial Disability Index physical function, and social/well-being function were -0.292, 0.570, 0.713, and 0.575, respectively. The SF-36 domains correlate best with the FaCE social function domain, with the strongest correlation between the both social function domains (r = 0.576). The FaCE score did statistically significantly increase in 35 patients receiving botulinum toxin type A (P = 0.042, Student t test). The domains 'facial comfort' and 'social function' improved statistically significantly as well (P = 0.022 and P = 0.046, respectively, Student t-test). The Dutch Facial Clinimetric Evaluation Scale shows good psychometric values and can be implemented in the management of Dutch-speaking patients with facial palsy in the Netherlands. Translation of the instrument into other languages may lead to widespread use, making evaluation and comparison possible among different providers.

To investigate the effect of social class and gender on self perceived health status for those recovering from an acute myocardial infarction. A longitudinal survey design was used, collecting both qualitative and quantitative data. Quantitative data are reported in this article, obtained by questionnaire over the first year after the event. SF-36 and EQ-5D (EuroQol) were used to measure self perceived health status. Community based study in a city in the north of England. A consecutive sample of 229 people discharged from hospital after acute myocardial infarction. Overall gain in health status was found to be statistically significant over the year. Improvements were greatest in domains relating to role fulfillment and pursuit of normal and social activities. When analysed by gender, women showed poorer improvement than men, particularly in the domains relating to physical and social functioning. Analysed by social class, those without educational qualifications showed poorer improvement in pain experience and vitality. Access to a car was significant in avoiding physical limitations and promoting general health. Existing gradients between the health of women and men, and between the social classes, are maintained and probably exacerbated by the experience of acute illness, and health professionals need to be made aware of social groups who are at risk of poor rehabilitation.

Cognitive behaviour therapy (CBT) reduces fatigue and disability in chronic fatigue syndrome (CFS). However, outcomes vary between studies, possibly because of differences in patient characteristics, treatment protocols, diagnostic criteria and outcome measures. The objective was to compare outcomes after CBT in tertiary treatment centres in the Netherlands (NL) and the United Kingdom (UK), using different treatment protocols but identical outcome measures, while controlling for differences in patient characteristics and diagnostic criteria. Consecutively referred CFS patients who received CBT were included (NL: n=293, UK: n=163). Uncontrolled effect sizes for improvement in fatigue (Chalder Fatigue Questionnaire), physical functioning (SF-36 physical functioning subscale) and social functioning (Work and Social Adjustment Scale) were compared. Multiple regression analysis was used to examine whether patient differences explained outcome differences between centres. Effect sizes differed between centres for fatigue (Cohen's D NL=1.74, 95% CI=1.52-1.95; UK=0.99, CI=0.73-1.25), physical functioning (NL=0.99, CI=0.81-1.18; UK=0.33, CI=0.08-0.58) and social functioning (NL=1.47, CI=1.26-1.69; UK=0.61, CI=0.35-0.86). Patients in the UK had worse physical functioning at baseline and there were minor demographic differences. These could not explain differences in centre outcome. Effectiveness of CBT differed between treatment centres. Differences in treatment protocols may explain this and should be investigated to help further improve outcomes.

X-ray fluctuation timescale and Black Hole mass relation in AGN

NASA Astrophysics Data System (ADS)

Wandel, Amri; Malkan, Mathew

We analyze the fluctuations in the X-ray flux of 20 AGN (mainly Seyfert 1 galaxies) monitored by RXTE and XMM-Newton with a sampling frequency ranging from hours to years, using structure function (SF) analysis. We derive SFs over four orders of magnitude in the time domain (0.03-300 days). Most objects show a characteristic time scale, where the SF flattens or changes slope. For 10 objects with published power-spectral density (PSD) the break time scales in the SF and PSD are similar and show a good correlation. We also find a significant correlation between the SF timescale and the mass of the central black hole, determined for most objects by reverberation mapping.

Informal caregivers of patients with Alzheimer's disease (AD) have a poor health-related quality of life (HRQOL). HRQOL is an increasingly common user-focused outcome measure. We have evaluated HRQOL longitudinally in caregivers of AD patients at baseline and at 12 months. Ninety-seven patients diagnosed with AD according to the NINCDS-ADRDA (National Institute of Neurological and Communicative Disorders and Stroke, and Alzheimer's Disease and Related Disorders Association) and their 97 respective primary caregivers were included in the study. We analysed the following data at the baseline visit: sociodemographic data of both patients and carers, patients' clinical variables, and data related to the healthcare provided to patients by carers. HRQOL of caregivers was measured with the SF-36 questionnaire at baseline and 12 months later. At 12 months, primary caregivers scored lower in the 8 subscales of the SF-36 questionnaire; differences were statistically significant in all dimensions except for 'physical function' and 'social function'. Baseline scores in our sample were lower than those of the general population. 'Vitality' is the dimension that presented the lowest scores. HRQOL in caregivers of patients with Alzheimer's disease deteriorates over time and is poorer than that of the age- and sex-matched general population.

To examine the potential effectiveness of a multimodal rehabilitation program including an acceptance-oriented cognitive-behavioral therapy for highly distressed patients with rheumatic diseases. An observational study employing a one-group pre-post test design (N=25). The primary outcome was psychological distress. Secondary outcomes were quality of life, illness acceptance, and coping flexibility. Group pre-to-post and pre-to-12 months follow-up treatment changes were evaluated by paired-samples t-tests and Cohen's effect sizes (d). Individual changes were evaluated by the reliable change index (RCI) and clinically significant change (CSC) parameters. Significant effects were found post-treatment and maintained at 12 months in psychological distress (d>0.80), illness acceptance (d=1.48) and the SF-36 subscales role physical, vitality, and mental health (d ≥ 0.65). No significant effects were found for coping flexibility and the SF-36 subscales physical functioning, bodily pain, social functioning, and role emotional. Both a reliable (RCI) and clinically significant (CSC) improvement was observed for almost half of the highly distressed patients. The patients enrolled in the multimodal rehabilitation program showed improved psychological health status from pre to post-treatment. A randomized clinical trial is needed to confirm or refute the added value of an acceptance-oriented cognitive-behavioral therapy for highly distressed patients in rehabilitation.

Skill-related physical fitness versus aerobic fitness as a predictor of executive functioning in children with intellectual disabilities or borderline intellectual functioning.

PubMed

Hartman, Esther; Smith, Joanne; Houwen, Suzanne; Visscher, Chris

2017-05-01

Children with intellectual disabilities (ID) or borderline intellectual disabilities (BIF) often demonstrate impairments in executive functioning (EF). Studies in typically developing children show that aerobic fitness (AF) is positively related with EF. Skill-related physical fitness (SF) might, however, be a stronger predictor of EF than AF, as cognitive challenges are inherent in application of these skills. In this study, AF and SF were examined simultaneously in relationship with domains of EF in children with ID or BIF. Seventy-three children (age range 8-11; 51 boys) with ID (IQ range 56-79) or BIF (IQ range 71-79) were measured annually over a period of 4 years on AF (20-m endurance shuttle run test) and SF (plate tapping and 10×5m run). EF was measured with the Stroop Color-Word test (inhibition), Trailmaking and Fluency test (cognitive flexibility), Self-ordered pointing task (working memory) and the Tower of London (planning). Multilevel models showed that SF was significantly associated with inhibition and both measures of cognitive flexibility, but in the same models no significant associations between AF and EF were found. In addition, age was significantly related to working memory and cognitive flexibility, favouring the older children. In children with ID or BIF, SF is of greater importance than AF in relationship with core domains of EF. Copyright © 2017 Elsevier Ltd. All rights reserved.

To determine the relationship between maternal attachment, perceived social support and breast-feeding sufficiency. Descriptive correlational design. A state hospital and two family health centers in Sakarya, Turkey, between June to December 2011. The sample was 122 voluntary mothers who had healthy babies of 1 - 2 months old. The data were collected by a Personal Information Form, Maternal Attachment Inventory (MAI), Multidimensional Scale of Perceived Social Support (MSPSS) and Breast-feeding Self-Efficacy Scale-Short Form (BSES-SF). The data collected were analysed by percentage distribution, mean square, independent sample t-test, Mann-Whitney U, Kruskall-Wallis and Pearson correlation. The mean age of the mothers was 25.01 ± 2.2 years, and 48.4% of them were primary school graduates. BSESSF was 61.02 ± 8.44 (16 - 70), MAI was 99.07 ± 7.19 (56 - 100) and MSPSS was 66.40 ± 13.58 (37 - 84). There was a positive, medium level, significant relationship between the total scores of BSES-SF and MAI (r=0.370, p < 0.001). There was a positive, medium level, significant relationship between the total score of BSES-SF and the score from family subdimension of MSPSS (r=0.255, p < 0.01).There was a positive, medium level, significant relationship between the total score of MAI and the total score of family subdimension of MSPSS (r=0.339, p < 0.001). Successful maternal attachment and familial support positively affected the breast-feeding sufficiency of the mother.

Direct modification and regulation of a nuclear receptor-PIP2 complex by the nuclear inositol-lipid kinase IPMK

PubMed Central

Blind, Raymond D.; Suzawa, Miyuki; Ingraham, Holly A.

2012-01-01

Phosphatidylinositol (4,5)-bisphosphate (PIP2) is best known as a plasma membrane-bound regulatory lipid. While PIP2 and phosphoinositide-modifying enzymes coexist in the nucleus, their roles in the nucleus remain unclear. Here we show that the nuclear inositol polyphosphate multikinase (IPMK), which functions both as an inositol- and a PI3-kinase, interacts with the nuclear receptor SF-1 (NR5A1) and phosphorylates its bound ligand, PIP2. IPMK failed to recognize SF-1/PIP2 after blocking or displacing PIP2 from SF-1’s large hydrophobic pocket. In contrast to IPMK, p110 catalytic subunits of type 1 PI3-kinases were inactive on SF-1/PIP2. These and other in vitro analyses demonstrated specificity of IPMK for the SF-1/PIP2 protein/lipid complex. Once generated, SF-1/PIP3 is readily dephosphorylated by the lipid phosphatase PTEN. Importantly, decreasing IPMK or increasing PTEN expression greatly reduced SF-1 transcriptional activity. This ability of lipid kinases and phosphatases to alter the activity and directly remodel a non-membrane protein/lipid complex such SF-1/PIP2, establishes a new pathway for promoting lipid-mediated signaling in the nucleus.

Sulforaphane absorption and excretion following ingestion of a semi-purified broccoli powder rich in glucoraphanin and broccoli sprouts in healthy men.

PubMed

Cramer, Jenna M; Jeffery, Elizabeth H

2011-01-01

Sulforaphane (SF) is a chemopreventive isothiocyanate (ITC) derived from the myrosinase-catalyzed hydrolysis of glucoraphanin, a thioglucoside present in broccoli. Broccoli supplements often contain glucoraphanin but lack myrosinase, putting in question their ability to provide dietary SF. This study compared the relative absorption of SF from air-dried broccoli sprouts rich in myrosinase and a glucoraphanin-rich broccoli powder lacking myrosinase, individually and in combination. Subjects (n=4) each consumed 4 meals consisting of dry cereal and yogurt with 2 g sprouts, 2 g powder, both, or neither. Blood and urine were analyzed for SF metabolites. The 24 h urinary SF recovery was 74%, 49%, and 19% of the dose ingested from broccoli sprouts, combination, and broccoli powder meals, respectively. Urinary and plasma ITC appearance was delayed from the broccoli powder compared to the sprouts and combination. A liver function panel indicated no toxicity from any treatment at 24 h. These data indicate a delayed appearance in plasma and urine of SF from the broccoli powder relative to SF from myrosinase-rich sprouts. Combining broccoli sprouts with the broccoli powder enhanced SF absorption from broccoli powder, offering the potential for development of foods that modify the health impact of broccoli products.

This study tested the measurement invariance of the Drinking Motives Questionnaire-Revised Short Form (DMQ-R-SF) in undergraduates across 10 countries. We expected the four-factor structure to hold across countries, and for social motives to emerge as the most commonly endorsed motive, followed by enhancement, coping and conformity motives. We also compared individualistic and collectivistic countries to examine potential differences in the endorsement of drinking motives when countries were divided according to this broad cultural value. A sample of 8478 undergraduate drinkers from collectivistic (Portugal, Mexico, Brazil, Spain; n = 1567) and individualistic (Switzerland, Hungary, Canada, the Netherlands, the UK and Ireland, and the USA; n = 6911) countries completed the DMQ-R-SF. Countries were classified as individualistic or collectivistic based on world-wide norms. Using multigroup confirmatory factor analysis, the 4-factor model of the DMQ-R-SF showed configural and metric invariance across all 10 countries. As predicted, the rank order of undergraduates' drinking motive endorsement was identical across countries (social > enhancement > coping > conformity), although a mixed model analysis of variance revealed a significant interaction where undergraduates from individualistic countries more strongly endorsed social and enhancement motives relative to undergraduates from collectivistic countries. There was broad cross-cultural consistency in the factor structure and mean patterns of drinking motives. Undergraduate students appear to drink mainly for positive reinforcement (i.e. for social and enhancement reasons), although this tendency is particularly pronounced among those from more individualistic countries.

2011-06-01

The Interpersonal Relationship Inventory-Short Form (IPRI-SF) has demonstrated psychometric consistency across several demographic and clinical populations; however, it has not been psychometrically tested in a military population. The purpose of this study was to psychometrically evaluate the reliability and component structure of the IPRI-SF in active duty United States Army female service members (FSMs). The reliability estimates were .93 for the social support subscale and .91 for the conflict subscale. Principal component analysis demonstrated an obliquely rotated three-component solution that accounted for 58.9% of the variance. The results of this study support the reliability and validity of the IPRI-SF for use in FSMs; however, a three-factor structure emerged in this sample of FSMs post-deployment that represents "cultural context."

We investigated the nutritional, cognitive and functional status in residents of two service-flat (SF) complexes and the effects of a nutrition education programme for care staff. Controlled nonrandomised study. Two SF complexes, that is community-assisted accommodation. Of 115 eligible SF residents, 80 subjects participated (age 83+/-7 y, 70% women). The nutritional status was assessed using body mass index (BMI, kg/m(2)), subjective global assessment (SGA), serum concentrations of albumin, insulin-like growth factor-I (IGF-I) and vitamin B(12). Cognitive and functional status were evaluated using the Mini Mental State Examination (MMSE, 0-30 points, <24 points indicates impaired cognition) and the Katz activities of daily living (ADL) index, respectively. Two assessments were made with a 5-month interval. At the start, a 12-h education programme was given to the staff at one of the SF complexes. At baseline, the means of BMI and the biochemical nutritional indices were normal, whereas one-third had BMI <22 kg/m(2) and one-fourth had lost > or =10% of previous weight. According to SGA, 30% demonstrated possible or serious malnutrition. The median MMSE was 23 points (19.5-26.5, 25-75th percentile). Nearly 70% were ADL-independent. At the 5-month follow-up there were no differences in the nutritional and cognitive status of the residents. The nutritional knowledge of the staff improved slightly (P<0.05) at both SF complexes (NS between groups). Around one-third of SF residents appeared to be at nutritional risk. Five months after a 12-h staff nutrition education programme, no objective changes were seen in the nutritional status of the SF residents.

CA150 represses RNA polymerase II (RNAPII) transcription by inhibiting the elongation of transcripts. The FF repeat domains of CA150 bind directly to the phosphorylated carboxyl-terminal domain of the largest subunit of RNAPII. We determined that this interaction is required for efficient CA150-mediated repression of transcription from the α4-integrin promoter. Additional functional determinants, namely, the WW1 and WW2 domains of CA150, were also required for efficient repression. A protein that interacted directly with CA150 WW1 and WW2 was identified as the splicing-transcription factor SF1. Previous studies have demonstrated a role for SF1 in transcription repression, and we found that binding of the CA150 WW1 and WW2 domains to SF1 correlated exactly with the functional contribution of these domains for repression. The binding specificity of the CA150 WW domains was found to be unique in comparison to known classes of WW domains. Furthermore, the CA150 binding site, within the carboxyl-terminal half of SF1, contains a novel type of proline-rich motif that may be recognized by the CA150 WW1 and WW2 domains. These results support a model for the recruitment of CA150 to repress transcription elongation. In this model, CA150 binds to the phosphorylated CTD of elongating RNAPII and SF1 targets the nascent transcript. PMID:11604498

One important aggression to human biology is constituted by metallic mercury intoxication, mainly expressed by neuropsychiatric disorders. To explore interaction between the domains of Quality of Life (QoL.) and neuro-muscular evidences in intoxicated people by the metal within an urban-industrial environment. 47 patients have been assessed, through SF36 application and semiological tests. Multiple regression was performed and, to test parameters estimated in adjustments, Student t test was used. Although there are low scores present in the instrument, there have been noticed good results in physical capacities. Muscular strength seems to be an influencing variable on physical and social functioning and mental health (p<0.05). Motor coordination influence on Vitality (p <0.05) was also remarked. As to equilibrium, it presents a negative interaction (p <0.03) with social functioning. Neuropsychiatric disorders influence negatively QoL perception, making people to subestime their motor performances. Complementarily, it is distinguished strength as physical capacity that presents positive interaction with the subjective perception of QV.

Data on the temporal relationships between duration of depression and recovery and functional disability are sparse. These relationships were examined in subjects from the general population (n = 250) with newly originated episodes of DSM-III-R major depression. The Netherlands Mental Health Survey and Incidence Study is a prospective epidemiological survey in the adult population (n = 7076), using the Composite International Diagnostic Interview (CIDI). Duration of depression and duration of recovery over 2 years were assessed with a life chart interview. Functional disabilities were assessed with the MOS-SF-36 and with absence days from work. Functional disabilities and absence days in depressed individuals were not found to be associated with duration of depression. Functioning in daily activities improved with longer duration of recovery but social functioning not. Functioning deteriorates by actual depressive symptomatology and comorbid anxiety but not by longer duration of depression. After symptomatic recovery, functioning improves to premorbid level, irrespective of the length of the depression. Improvements in daily activities and work can be expected with longer duration of recovery.

Isolation, characterization and comparative genomics of bacteriophage SfIV: a novel serotype converting phage from Shigella flexneri

PubMed Central

2013-01-01

Background Shigella flexneri is the major cause of shigellosis in the developing countries. The O-antigen component of the lipopolysaccharide is one of the key virulence determinants required for the pathogenesis of S. flexneri. The glucosyltransferase and/or acetyltransferase genes responsible for the modification of the O-antigen are encoded by temperate serotype converting bacteriophage present in the S. flexneri genome. Several serotype converting phages have previously been isolated and characterized, however, attempts to isolate a serotype converting phage which encodes the modification genes of serotypes 4a strain have not been successful. Results In this study, a novel temperate serotype converting bacteriophage SfIV was isolated. Lysogenisation of phage SfIV converted serotype Y strain to serotype 4a. Electron microscopy indicated that SfIV belongs to Myoviridae family. The 39,758 bp genome of phage SfIV encompasses 54 open reading frames (orfs). Protein level comparison of SfIV with other serotype converting phages of S. flexneri revealed that SfIV is similar to phage SfII and SfV. The comparative analysis also revealed that SfIV phage contained five proteins which were not found in any other phages of S. flexneri. These proteins were: a tail fiber assembly protein, two hypothetical proteins with no clear function, and two other unknown proteins which were encoded by orfs present on a moron, that presumably got introduced in SfIV genome from another species via a transposon. These unique proteins of SfIV may play a role in the pathogenesis of the host. Conclusions This study reports the isolation and complete genome sequence analysis of bacteriophage SfIV. The SfIV phage has a host range significantly different from the other phages of Shigella. Comparative genome analysis identified several proteins unique to SfIV, which may potentially be involved in the survival and pathogenesis of its host. These findings will further our understanding on the evolution of these phages, and will also facilitate studies on development of new phage vectors and therapeutic agents to control infections caused by S. flexneri.

The study Pesquisa Dimensões Sociais das Desigualdades (PDSD) (Social Dimensions of Inequalities) involves 12,423 randomly selected Brazilian men and women aged 18 years old or more from urban and rural areas of the five Brazilian regions, and the information collected included the SF-36 as a measure of health-related quality of life. This provided a unique opportunity to develop age and gender-adjusted normative data for the Brazilian population. Brazilian men scored substantially higher than women on all eight domains and the two summary component scales of the SF-36. Brazilians scored less than their international counterparts on almost all of SF-36 domains and both summary component scales, except on general health status (US), pain (UK) and vitality (Australia, US and Canada). The differences in the SF-36 scores between age groups, genders and countries confirm that these Brazilian norms are necessary for comparative purposes. The data will be useful for assessing the health status of the general population and of patient populations, and the effect of interventions on health-related quality of life.

Pure silk fibroin (SF) hydrogel and polycarbazole/silk fibroin (SF/PCZ) hydrogels were fabricated by solvent casting technique to evaluate electromechanical responses, dielectric properties, and cantilever deflection properties as functions of electric field strength, SF concentration, glutaraldehyde concentration, and PCZ concentration in the blends. Electromechanical properties were characterized in oscillatory shear mode at electric field strengths ranging from 0 to 600V/mm and at a temperature of 27°C. For both the pristine SF and SF/PCZ hydrogels, the storage modulus response (ΔG') and the storage modulus sensitivity (ΔG'/G'0) increased dramatically with increasing electric field strength. The pristine hydrogel possessed the highest storage modulus sensitivity value of 5.87, a relatively high value when compared with other previously studied electroactive polymers. With the addition of conductive PCZ in SF hydrogel, the storage modulus sensitivity and the relative dielectric constant decreased; the conductive polymer thus provided the softening effect under electric field. In the deflection response, the dielectrophoresis force and deflection distance increased monotonically with electric field strength, where the pure SF hydrogel showed the highest deflection distance and dielectrophoresis force.

Singlet fission (SF), the spontaneous down-conversion of a singlet exciton into two triplet excitons residing on neighboring molecules, is a promising route to improve organic photovoltaic (OPV) device efficiencies by harvesting two charge carriers from one photon. However, only a few materials have been discovered that exhibit intermolecular SF in the solid state, most of which are acene derivatives. Recently, there has been a growing interest in rylenes as potential SF materials. We use many-body perturbation theory in the GW approximation and the Bethe-Salpeter equation to investigate the possibility of intermolecular SF in crystalline perylene and quaterrylene. A new method is presented for determining the percent charge transfer (%CT) character of an exciton wave-function from double-Bader analysis. This enables relating exciton probability distributions to crystal packing. Based on comparison to known and predicted SF materials with respect to the energy conservation criterion (ES-2ET) and %CT, crystalline quaterrylene is a promising candidate for intermolecular SF. Furthermore, quaterrylene is attractive for OPV applications, thanks to its high stability and narrow optical gap. Perylene is not expected to exhibit SF; however, it is a promising candidate for harvesting sub-gap photons by triplet-triplet annihilation.

The outbreak of Zika virus (ZIKV) and associated fetal microcephaly mandates efforts to understand the molecular processes of infection. Related flaviviruses produce noncoding subgenomic flaviviral RNAs (sfRNAs) that are linked to pathogenicity in fetal mice. These viruses make sfRNAs by co-opting a cellular exonuclease via structured RNAs called xrRNAs. We found that ZIKV-infected monkey and human epithelial cells, mouse neurons, and mosquito cells produce sfRNAs. The RNA structure that is responsible for ZIKV sfRNA production forms a complex fold that is likely found in many pathogenic flaviviruses. Mutations that disrupt the structure affect exonuclease resistance in vitro and sfRNA formationmore » during infection. The complete ZIKV xrRNA structure clarifies the mechanism of exonuclease resistance and identifies features that may modulate function in diverse flaviviruses.« less

The Human Splicing Factor ASF/SF2 can Specifically Recognize Pre-mRNA 5' Splice Sites

NASA Astrophysics Data System (ADS)

Zuo, Ping; Manley, James L.

1994-04-01

ASF/SF2 is a human protein previously shown to function in in vitro pre-mRNA splicing as an essential factor necessary for all splices and also as an alternative splicing factor, capable of switching selection of 5' splice sites. To begin to study the protein's mechanism of action, we have investigated the RNA binding properties of purified recombinant ASF/SF2. Using UV crosslinking and gel shift assays, we demonstrate that the RNA binding region of ASF/SF2 can interact with RNA in a sequence-specific manner, recognizing the 5' splice site in each of two different pre-mRNAs. Point mutations in the 5' splice site consensus can reduce binding by as much as a factor of 100, with the largest effects observed in competition assays. These findings support a model in which ASF/SF2 aids in the recognition of pre-mRNA 5' splice sites.

Introduction Delayed notification and lack of early information hinder timely hospital based activations in large scale multiple casualty events. We hypothesized that Twitter real-time data would produce a unique and reproducible signal within minutes of multiple casualty events and we investigated the timing of the signal compared with other hospital disaster notification mechanisms. Methods Using disaster specific search terms, all relevant tweets from the event to 7 days post-event were analyzed for 5 recent US based multiple casualty events (Boston Bombing [BB], SF Plane Crash [SF], Napa Earthquake [NE], Sandy Hook [SH], and Marysville Shooting [MV]). Quantitative and qualitative analysis of tweet utilization were compared across events. Results Over 3.8 million tweets were analyzed (SH 1.8 m, BB 1.1m, SF 430k, MV 250k, NE 205k). Peak tweets per min ranged from 209–3326. The mean followers per tweeter ranged from 3382–9992 across events. Retweets were tweeted a mean of 82–564 times per event. Tweets occurred very rapidly for all events (<2 mins) and represented 1% of the total event specific tweets in a median of 13 minutes of the first 911 calls. A 200 tweets/min threshold was reached fastest with NE (2 min), BB (7 min), and SF (18 mins). If this threshold was utilized as a signaling mechanism to place local hospitals on standby for possible large scale events, in all case studies, this signal would have preceded patient arrival. Importantly, this threshold for signaling would also have preceded traditional disaster notification mechanisms in SF, NE, and simultaneous with BB and MV. Conclusions Social media data has demonstrated that this mechanism is a powerful, predictable, and potentially important resource for optimizing disaster response. Further investigated is warranted to assess the utility of prospective signally thresholds for hospital based activation. PMID:28982201

LRH-1 May Rescue SF-1 Deficiency for Steroidogenesis: An in vitro and in vivo Study.

Steroidogenic factor 1 (NR5A1/SF-1) mutations usually manifest in 46,XY individuals with variable degrees of disordered sex development and in 46,XX women with ovarian insufficiency. So far, there is no genotype-phenotype correlation. The broad spectrum of phenotype with NR5A1 mutations may be due to a second hit in a gene with similar function to NR5A1/SF-1. Liver receptor homologue-1 (LRH-1/NR5A2) might be a good candidate. We performed in vitro studies for the interplay between SF-1, LRH-1 and DAX-1, expression profiles in human steroidogenic tissues, and NR5A2 genetic studies in a cohort (11 patients, 8 relatives, 11 families) harboring heterozygote NR5A1/SF-1 mutations. LRH-1 isoforms transactivate the CYP17A1 and HSD3B2 promoters similarly to SF-1 and compensate for SF-1 deficiency. DAX-1 inhibits SF-1- and LRH-1-mediated transactivation. LRH-1 is found expressed in human adult and fetal adrenals and testes. However, no NR5A2/LRH-1 mutations were detected in 14 individuals with heterozygote NR5A1/SF-1 mutations. These findings demonstrate that in vitro LRH-1 can act like SF-1 and compensate for its deficiency. Expression of LRH-1 in fetal testis suggests a role in male gonadal development. However, as we found no NR5A2/LRH-1 mutations, the 'second genetic hit' in SF-1 patients explaining the broad phenotypic variability remains elusive. © 2015 S. Karger AG, Basel.

To determine whether demographic factors and coping strategies are related to quality of life in heart transplant candidates. Participants were 50 inpatients being evaluated for heart transplant. Coping was measured using the COPE Inventory (1) (J Pers Soc Psychol, 56, 1989, 267). Quality of life was assessed using the SF-36 (2) (Health Survey: Manual and Interpretation Guide, Quality Metric Inc, Lincoln, RI, 2000). Higher education and less seeking of social support were independently associated with better physical functioning. Higher use of denial was associated with poorer mental health functioning. In patients with significant physical limitations, years of education appears to be protective. Less seeking of social support was associated with better physical functioning perhaps because individuals who feel better physically do not feel the need to elicit support. Alternatively, the tendency to not seek assistance could stem from personality characteristics such as avoidance or optimism. Denial was associated with worse mental health functioning. Denying the existence of a stressor may be a high risk coping strategy for patients who are pre-transplant and even more dangerous for those who are post-transplant given the need to be alert to symptoms. Proactive identification of patients at risk for poorer quality of life will allow for more timely psychosocial interventions, which could impact post-transplant outcomes.

Steroidogenic Factor-1 (SF-1, Ad4BP, NR5A1) and Disorders of Testis Development

PubMed Central

Lin, L.; Achermann, J.C.

2009-01-01

Steroidogenic factor-1 (SF-1) (Ad4BP, NR5A1) is a nuclear receptor that regulates many aspects of adrenal and reproductive development and function. Consequently, deletion of the gene (Nr5a1) encoding Sf-1 in XY mice results in impaired adrenal development, complete testicular dysgenesis with Müllerian structures, and female external genitalia. Initial efforts to identify NR5A1 changes in humans focused on 46,XY individuals with combined adrenogonadal failure and Müllerian structures. Although this combination of clinical features is rare, 2 such patients harboring NR5A1 mutations have been described within the past decade. More recently, however, it has emerged that heterozygous loss of function mutations in NR5A1 can be found relatively frequently in children and adults with 46,XY disorders of sex development (DSD) but with apparently normal adrenal function. The phenotypic spectrum associated with these changes ranges from complete testicular dysgenesis with Müllerian structures, through individuals with mild clitoromegaly or genital ambiguity, to severe penoscrotal hypospadias or even anorchia. Furthermore, a non-synonymous polymorphism in NR5A1 may be associated with micropenis or undescended testes within the population. Taken together, these reports suggest that variable loss of SF-1 function can be associated with a wide range of reproductive phenotypes in humans. PMID:18987494

Silk proteins are natural biopolymers that have extensive structural possibilities for chemical and mechanical modifications to facilitate novel properties, functions, and applications in the biomedical field. The versatile processability of silk fibroins (SF) into different forms such as gels, films, foams, membranes, scaffolds, and nanofibers makes it appealing in a variety of applications that require mechanically superior, biocompatible, biodegradable, and functionalizable biomaterials. There is no doubt that nature is the world's best biological engineer, with simple, exquisite but powerful designs that have inspired novel technologies. By understanding the surface interaction of silk materials with living cells, unique characteristics can be implemented through structural modifications, such as controllable wettability, high-strength adhesiveness, and reflectivity properties, suggesting its potential suitability for surgical, optical, and other biomedical applications. All of the interesting features of SF, such as tunable biodegradation, anti-bacterial properties, and mechanical properties combined with potential self-healing modifications, make it ideal for future tissue engineering applications. In this review, we first demonstrate the current understanding of the structures and mechanical properties of SF and the various functionalizations of SF matrices through chemical and physical manipulations. Then the diverse applications of SF architectures and scaffolds for different regenerative medicine will be discussed in detail, including their current applications in bone, eye, nerve, skin, tendon, ligament, and cartilage regeneration.

As a contribution to the functionality of scaffolds in tissue engineering, here we report on advanced scaffold design through introduction and evaluation of topographical, mechanical and chemical cues. For scaffolding, we used silk fibroin (SF), a well established biomaterial. Biomimetic alignment of fibers was achieved as a function of the rotational speed of the cylindrical target during electrospinning of a SF solution blended with polyethylene oxide. Seeding fibrous SF scaffolds with human mesenchymal stem cells (hMSC) demonstrated that fiber alignment could guide hMSC morphology and orientation demonstrating the impact of scaffold topography on the engineering of oriented tissues. Beyond currently established methodologies to measure bulk properties, we assessed the mechanical properties of the fibers by conducting extension at breakage experiments on the level of single fibers. Chemical modification of the scaffolds was tested using donor/acceptor fluorophore labeled fibronectin. Fluorescence resonance energy transfer imaging allowed to assess the conformation of fibronectin when adsorbed on the SF scaffolds, and demonstrated an intermediate extension level of its subunits. Biological assays based on hMSC showed enhanced cellular adhesion and spreading as a result of fibronectin adsorbed on the scaffolds. Our studies demonstrate the versatility of SF as a biomaterial to engineer modified fibrous scaffolds and underscore the use of biofunctionally relevant analytical assays to optimize fibrous biomaterial scaffolds.

Reading laterally: the cerebral hemispheric use of spatial frequencies in visual word recognition.

2013-01-04

It is generally accepted that the left hemisphere (LH) is more capable for reading than the right hemisphere (RH). Left hemifield presentations (initially processed by the RH) lead to a globally higher error rate, slower word identification, and a significantly stronger word length effect (i.e., slower reaction times for longer words). Because the visuo-perceptual mechanisms of the brain for word recognition are primarily localized in the LH (Cohen et al., 2003), it is possible that this part of the brain possesses better spatial frequency (SF) tuning for processing the visual properties of words than the RH. The main objective of this study is to determine the SF tuning functions of the LH and RH for word recognition. Each word image was randomly sampled in the SF domain using the SF bubbles method (Willenbockel et al., 2010) and was presented laterally to the left or right visual hemifield. As expected, the LH requires less visual information than the RH to reach the same level of performance, illustrating the well-known LH advantage for word recognition. Globally, the SF tuning of both hemispheres is similar. However, these seemingly identical tuning functions hide important differences. Most importantly, we argue that the RH requires higher SFs to identify longer words because of crowding.

Abnormal Size-Dependent Modulation of Motion Perception in Children with Autism Spectrum Disorder (ASD)

2017-01-01

Excitation/Inhibition (E/I) imbalance in neural networks is now considered among the core neural underpinnings of autism psychopathology. In motion perception at least two phenomena critically depend on E/I balance in visual cortex: spatial suppression (SS), and spatial facilitation (SF) corresponding to impoverished or improved motion perception with increasing stimuli size, respectively. While SS is dominant at high contrast, SF is evident for low contrast stimuli, due to the prevalence of inhibitory contextual modulations in the former, and excitatory ones in the latter case. Only one previous study (Foss-Feig et al., 2013) investigated SS and SF in Autism Spectrum Disorder (ASD). Our study aimed to replicate previous findings, and to explore the putative contribution of deficient inhibitory influences into an enhanced SF index in ASD—a cornerstone for interpretation proposed by Foss-Feig et al. (2013). The SS and SF were examined in 40 boys with ASD, broad spectrum of intellectual abilities (63 < IQ < 127) and 44 typically developing (TD) boys, aged 6–15 years. The stimuli of small (1°) and large (12°) radius were presented under high (100%) and low (1%) contrast conditions. Social Responsiveness Scale and Sensory Profile Questionnaire were used to assess the autism severity and sensory processing abnormalities. We found that the SS index was atypically reduced, while SF index abnormally enhanced in children with ASD. The presence of abnormally enhanced SF in children with ASD was the only consistent finding between our study and that of Foss-Feig et al. While the SS and SF indexes were strongly interrelated in TD participants, this correlation was absent in their peers with ASD. In addition, the SF index but not the SS index correlated with the severity of autism and the poor registration abilities. The pattern of results is partially consistent with the idea of hypofunctional inhibitory transmission in visual areas in ASD. Nonetheless, the absence of correlation between SF and SS indexes paired with a strong direct link between abnormally enhanced SF and autism symptoms in our ASD sample emphasizes the role of the enhanced excitatory influences by themselves in the observed abnormalities in low-level visual phenomena found in ASD.

The splicing factor SF3B1 is the most commonly mutated gene in the myelodysplastic syndrome (MDS), particularly in patients with refractory anemia with ring sideroblasts (RARS). We investigated the functional effects of SF3B1 disruption in myeloid cell lines: SF3B1 knockdown resulted in growth inhibition, cell cycle arrest and impaired erythroid differentiation and deregulation of many genes and pathways, including cell cycle regulation and RNA processing. MDS is a disorder of the hematopoietic stem cell and we thus studied the transcriptome of CD34(+) cells from MDS patients with SF3B1 mutations using RNA sequencing. Genes significantly differentially expressed at the transcript and/or exon level in SF3B1 mutant compared with wild-type cases include genes that are involved in MDS pathogenesis (ASXL1 and CBL), iron homeostasis and mitochondrial metabolism (ALAS2, ABCB7 and SLC25A37) and RNA splicing/processing (PRPF8 and HNRNPD). Many genes regulated by a DNA damage-induced BRCA1-BCLAF1-SF3B1 protein complex showed differential expression/splicing in SF3B1 mutant cases. This is the first study to determine the target genes of SF3B1 mutation in MDS CD34(+) cells. Our data indicate that SF3B1 has a critical role in MDS by affecting the expression and splicing of genes involved in specific cellular processes/pathways, many of which are relevant to the known RARS pathophysiology, suggesting a causal link.

N-acetylglucosaminyltransferase I (GNT-I) contributes to branch point intermediate production and can potentially reverse the FDL trimming reaction. However, there has been no concerted effort to evaluate the relationships among these three enzymes in any single insect system. Hence, we extended our previous studies on Spodoptera frugiperda (Sf) FDL to include GNT-I and -II. Sf-GNT-I and -II cDNAs were isolated, the predicted protein sequences were analyzed, and both gene products were expressed and their acceptor substrate specificities and intracellular localizations were determined. Sf-GNT-I transferred N-acetylglucosamine to Man(5)GlcNAc(2), Man(3)GlcNAc(2), and GlcNAc(β1-2)Man(α1-6)[Man(α1-3)]ManGlcNAc(2), demonstrating its role in branch point intermediate production and its ability to reverse FDL trimming. Sf-GNT-II only transferred N-acetylglucosamine to Man(α1-6)[GlcNAc(β1-2)Man(α1-3)]ManGlcNAc(2), demonstrating that it initiates complex N-glycan production, but cannot use Man(3)GlcNAc(2) to produce hybrid or complex structures. Fluorescently tagged Sf-GNT-I and -II co-localized with an endogenous Sf Golgi marker and Sf-FDL co-localized with Sf-GNT-I and -II, indicating that all three enzymes are Golgi resident proteins. Unexpectedly, fluorescently tagged Drosophila melanogaster FDL also co-localized with Sf-GNT-I and an endogenous Drosophila Golgi marker, indicating that it is a Golgi resident enzyme in insect cells. Thus, the substrate specificities and physical juxtapositioning of GNT-I, GNT-II, and FDL support the idea that these enzymes function at the N-glycan processing branch point and are major factors determining the net outcome of the insect cell N-glycosylation pathway.

The use of tracheoesophageal speech with voice prosthesis (T-E speech) after total laryngectomy has increased recently as a method of vocalization following laryngeal cancer. Previous research has not investigated the relationship between quality of life (QOL) and phonatory function in those using T-E speech. This study aimed to demonstrate the relationship between phonatory function and both comprehensive health-related QOL and QOL related to speech in people using T-E speech. The subjects of the study were 20 male patients using T-E speech after total laryngectomy. At a visit to our clinic, the subjects underwent a phonatory function test and completed three questionnaires: the MOS 8-Item Short-Form Health Survey (SF-8), the Voice Handicap Index-10 (VHI-10), and the Voice-Related Quality of Life (V-RQOL) Measure. A significant correlation was observed between the physical component summary (PCS), a summary score of SF-8, and VHI-10. Additionally, a significant correlation was observed between the SF-8 mental component summary (MCS) and both VHI-10 and VRQOL. Significant correlations were also observed between voice intensity in the phonatory function test and both VHI-10 and V-RQOL. Finally, voice intensity was significantly correlated with the SF-8 PCS. QOL questionnaires and phonatory function tests showed that, in people using T-E speech after total laryngectomy, voice intensity was correlated with comprehensive QOL, including physical and mental health. This finding suggests that voice intensity can be used as a performance index for speech rehabilitation.

Awake craniotomy pursues a balance between extensive tumor resection and preservation of postoperative language function. A dilemma exists in patients whose tumor resection is restricted due to signs of language impairment observed during awake craniotomy. In order to determine the degree to which recovery of language function caused by tumor resection can be achieved by spontaneous neuroplasticity, the change in postoperative language function was compared to quantified intraoperative linguistic performance. The modified, short-form Boston Diagnostic Aphasia Examination (sfBDAE) was used to assess pre- and postoperative language functions; visual object naming (DO 80) and semantic-association (Pyramid and Palm Tree Test, PPTT) tests assessed intraoperative linguistic performance. DO 80 and PPTT were performed alternatively during subcortical functional monitoring while performing tumor resection and sfBDAE was assessed 1-week postoperatively. Most patients with observed language impairment during awake surgery showed improved language function postoperatively. Both intraoperative DO 80 and PPTT showed significant correlation to postoperative sfBDAE domain scores (p < 0.05), with a higher correlation observed with PPTT. A linear regression model showed that only PPTT predicted the postoperative sfBDAE domain scores with the adjusted R 2 ranging from 0.51 to 0.89 (all p < 0.01). Receiver operating characteristic analysis showed a cutoff value of PPTT that yielded a sensitivity of 80% and specificity of 100%. PPTT may be a feasible tool for intraoperative linguistic evaluation that can predict postoperative language outcomes. Further studies are needed to determine the extent of tumor resection that optimizes the postoperative language following neuroplasticity.

Patients with progressive multiple sclerosis (MS) often have cognitive impairment in addition to physical impairment. The burden of cognitive and physical impairment progresses over time, and may be major determinants of quality of life. The aim of this study was to assess to which degree quality of life correlates with physical and cognitive function in progressive MS. This is a retrospective study of 52 patients with primary progressive ( N  = 18) and secondary progressive MS ( N  = 34). Physical disability was assessed using the Expanded Disability Status Scale, Timed 25 Foot Walk (T25FW) test and 9-Hole Peg Test (9HPT). Cognitive function was assessed using Symbol Digit Modalities Test (SDMT), Paced Auditory Serial Addition Test, and Trail Making Test B (TRAIL-B). In addition, quality of life was assessed by the Short Form 36 (SF-36) questionnaire. Only measures of cognitive function correlated with the overall SF-36 quality of life score and the Mental Component Summary score from the SF-36. The only physical measure that correlated with a measure of quality of life was T25FW test, which correlated with the Physical Component Summary from the SF-36. We found no other significant correlations between the measures of cognitive function and the overall physical measures but interestingly, we found a possible relationship between the 9HPT score for the nondominant hand and the SDMT and TRAIL-B. Our findings support inclusion of measures of cognitive function in the assessment of patients with progressive MS as these correlated closer with quality of life than measures of physical impairment.

Urease from Helicobacter pylori is inactivated by sulforaphane and other isothiocyanates

Infections by Helicobacter pylori are very common, causing gastroduodenal inflammation including peptic ulcers, and increasing the risk of gastric neoplasia. The isothiocyanate (ITC) sulforaphane [SF; 1-isothiocyanato-4-(methylsulfinyl)butane] derived from edible crucifers such as broccoli is potently bactericidal against Helicobacter, including antibiotic-resistant strains, suggesting a possible dietary therapy. Gastric H. pylori infections express high urease activity which generates ammonia, neutralizes gastric acidity, and promotes inflammation. The finding that SF inhibits (inactivates) urease (jack bean and Helicobacter) raised the issue of whether these properties might be functionally related. The rates of inactivation of urease activity depend on enzyme and SF concentrations and show first order kinetics. Treatment with SF results in time-dependent increases in the ultraviolet absorption of partially purified Helicobacter urease in the 280–340 nm region. This provides direct spectroscopic evidence for the formation of dithiocarbamates between the ITC group of SF and cysteine thiols of urease. The potencies of inactivation of Helicobacter urease by isothiocyanates structurally related to SF were surprisingly variable. Natural isothiocyanates closely related to SF, previously shown to be bactericidal (berteroin, hirsutin, phenethyl isothiocyanate, alyssin, and erucin), did not inactivate urease activity. Furthermore, SF is bactericidal against both urease positive and negative H. pylori strains. In contrast, some isothiocyanates such as benzoyl-ITC, are very potent urease inactivators, but are not bactericidal. The bactericidal effects of SF and other ITC against Helicobacter are therefore not obligatorily linked to urease inactivation, but may reduce the inflammatory component of Helicobacter infections.

Previous studies suggested that pre-operative comorbidity was a risk factor for worse outcomes after TKA. To our knowledge, studies have not examined whether postoperative changes in comorbidity impact pain and function outcomes longitudinally. Our objective was to examine if increasing comorbidity postoperatively is associated with worsening physical function and pain after primary total knee arthroplasty (TKA). We performed a retrospective chart review of veterans who had completed Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) and Short Form-36 (SF36) surveys at regular intervals after primary TKA. Comorbidity was assessed using a variety of scales: validated Charlson comorbidity index score, and a novel Arthroplasty Comorbidity Severity Index score (Including medical index, local musculoskeletal index [including lower extremity and spine] and TKA-related index subscales; higher scores are worse ), at multiple time-points post-TKA. We used mixed model linear regression to examine the association of worsening comorbidity post-TKA with change in WOMAC and SF-36 scores in the subsequent follow-up periods, controlling for age, length of follow-up, and repeated observations. The study cohort consisted of 124 patients with a mean age of 71.7 years (range 58.6-89.2, standard deviation (SD) 6.9) followed for a mean of 4.9 years post-operatively (range 1.3-11.4; SD 2.8). We found that post-operative worsening of the Charlson Index score was significantly associated with worsening SF-36 Physical Function (PF) (beta coefficient (ß) = -0.07; p < 0.0001), SF-36 Bodily Pain (BP) (ß = -0.06; p = 0.002), and WOMAC PF subscale (ß = 0.08; p < 0.001; higher scores are worse) scores, in the subsequent periods. Worsening novel medical index subscale scores were significantly associated with worsening SF-36 PF scores (ß = -0.03; p = 0.002), SF-36 BP (ß = -0.04; p < 0.001) and showed a non-significant trend for worse WOMAC PF scores (ß = 0.02; p = 0.11) subsequently. Local musculoskeletal index subscale scores were significantly associated with worsening SF-36 PF (ß = -0.05; p = 0.001), SF-36 BP (ß = -0.04; p = 0.03) and WOMAC PF (ß = 0.06; p = 0.01) subsequently. None of the novel index subscale scores were significantly associated with WOMAC pain scores. TKA complications, as assessed by TKA-related index subscale,  were not significantly associated with SF-36 or WOMAC domain scores. Increasing Charlson index as well as novel medical and local musculoskeletal index subscale scores (from novel Arthroplasty  Comorbidity Severity Index) post-TKA correlated with subsequent worsening of physical function and pain outcomes post-TKA. Further studies should examine which comorbidity management could have the greatest impact on these outcomes.

Biochemical analysis of the biosynthetic pathway of an anticancer tetracycline SF2575.

SF2575 1 is a tetracycline polyketide produced by Streptomyces sp. SF2575 and displays exceptionally potent anticancer activity toward a broad range of cancer cell lines. The structure of SF2575 is characterized by a highly substituted tetracycline aglycon. The modifications include methylation of the C-6 and C-12a hydroxyl groups, acylation of the 4-(S)-hydroxyl with salicylic acid, C-glycosylation of the C-9 of the D-ring with D-olivose and further acylation of the C4'-hydroxyl of D-olivose with the unusual angelic acid. Understanding the biosynthesis of SF2575 can therefore expand the repertoire of enzymes that can modify tetracyclines, and facilitate engineered biosynthesis of SF2575 analogues. In this study, we identified, sequenced, and functionally analyzed the ssf biosynthetic gene cluster which contains 40 putative open reading frames. Genes encoding enzymes that can assemble the tetracycline aglycon, as well as installing these unique structural features, are found in the gene cluster. Biosynthetic intermediates were isolated from the SF2575 culture extract to suggest the order of pendant-group addition is C-9 glycosylation, C-4 salicylation, and O-4' angelylcylation. Using in vitro assays, two enzymes that are responsible for C-4 acylation of salicylic acid were identified. These enzymes include an ATP-dependent salicylyl-CoA ligase SsfL1 and a putative GDSL family acyltransferase SsfX3, both of which were shown to have relaxed substrate specificity toward substituted benzoic acids. Since the salicylic acid moiety is critically important for the anticancer properties of SF2575, verification of the activities of SsfL1 and SsfX3 sets the stage for biosynthetic modification of the C-4 group toward structure-activity relationship studies of SF2575. Using heterologous biosynthesis in Streptomyces lividans, we also determined that biosynthesis of the SF2575 tetracycline aglycon 8 parallels that of oxytetracycline 4 and diverges after the assembly of 4-keto-anhydrotetracycline 51. The minimal ssf polyketide synthase together with the amidotransferase SsfD produced the amidated decaketide backbone that is required for the formation of 2-naphthacenecarboxamide skeleton. Additional enzymes, such as cyclases C-6 methyltransferase and C-4/C-12a dihydroxylase, were functionally reconstituted.

Functional outcomes after ileal bladder substitution reflect the expectations of future patients at a particular centre. The aim of this study was to use validated questionnaires and a pad-weighing test to investigate functional outcomes after neobladder reconstruction at long-term follow-up in patients at a single centre. During 2005 - 2015, 75 patients received a Studer ileal bladder substitute at the Department of Urology, Malmö. Forty-six of these patients were alive for follow-up and were evaluated using the pad-weighing test and the International Consultation on Incontinence Questionnaire-Urinary Incontinence Short Form (ICIQ-UI-SF), the Female Sexual Function Index (FSFI) and the International Index of Erectile Function (IIEF). Five of 37 evaluable patients (14%) were considered fully continent, reporting a pad-weighing test result of 0 g and an ICIQ-UI-SF score of 0. The median ICIQ-UI-SF score was 8 [interquartile range (IQR) 3-11], and seven patients (17%) were continent according to the ICIQ-UI-SF score only. In the pad-weighing test, 28 out of 37 patients (76%) reported 0 g day-time leakage whereas only 12 out of 37 patients (32%) reported 0 g night-time leakage. At follow-up, nine out of 39 (23%) of evaluable male patients were potent. The median ICIQ-UI-SF score was significantly lower during the second half of the study period [4 (IQR 0-8) vs 10 (IQR 6-14); p = .003]. The inverse applied to the median IIEF score [5 (IQR 3-12) vs 2 (IQR 1-4); p = .02]. Functional outcomes at long-term follow-up after radical cystectomy and Studer ileal bladder substitute were at best modest in this series. Better outcomes during the second half of the study period might be explained by improved patient selection and a refined surgical technique, but possibly also by longer follow-up of patients during the first half of the period resulting in a more pronounced time-dependent decline in functional outcomes.

Obesity is a critical social and health issue, adversely impacting life expectancy, quality of life, and mental health. Minorities are disproportionately impacted by obesity with African Americans experiencing the highest prevalence among minority groups. The aim of this study was to determine if a lifestyle program that integrated chair exercises, nutrition and educational counseling, and scripture readings would help under-served obese African American women make lifestyle changes that would positively impact their quality of life, especially mental health. A repeated measures intervention study was conducted (24-weeks). Weeks 1-12 involved meeting twice a week for a total of 4h with participants engaged in chair exercises, educational counseling, and scripture readings. During weeks 13-24, the participants were "on their own" but were encouraged to exercise and eat healthy. Focus groups were held at 12 and 24-weeks. Participants were recruited from a nurse managed center and a primary care clinic for the uninsured. Mental health data were collected at baseline, 12, and 24-weeks. The Medical Outcomes Study Short Form Version 2 (SF-36v2) was used to measure changes in mental health. Higher scores indicate better perceived health status. Group scores less than 47 indicate impaired functioning. 55 women had complete data for all three data collection points, with a mean age of 50 and a mean BMI of 41.2. Repeated ANOVAs detected significant differences on the mental component summary of the SF-36v2: this score improved from baseline (M=44.1) to 12-weeks (M=50.7) but decreased at 24-weeks (M=47.9) (p=.000). The four domains (vitality, social functioning, role emotional, mental health) were also significantly different over the three data collection points. The findings have significant implications for psychiatric nurses in terms of education, clinical practice, and future research. The study contributed to the participants' mental health through the various group activities including scripture readings, socialization with "like minded" women and structured exercises. These findings offer psychiatric nurses additional tools for effective care. Copyright © 2014 Elsevier Inc. All rights reserved.

This study presents an instrument, the health-related quality of life (HRQOL) profile for independent elderly, to measure the health-related quality of life of the functionally independent elderly assisted in the outpatient setting, based on the adaptation of four validated scales: Short-Form Health Survey (SF-36), Duke-UNC Health Profile (DUHP), Sickness Impact Profile (SIP), and Nottingham Health Profile (NHP). The study also evaluates the instrument's reliability based on its use by two different observers with a 15-day interval. The instrument includes five dimensions (health perception, symptoms, physical function, psychological function, and social function) and 45 items. Reliability evaluation of the QUASI instrument was based on interviews with 142 elderly outpatients in the city of Rio de Janeiro, Brazil. Prevalence-adjusted kappa statistic was used to assess all 45 items. Correlation was also calculated between overall scores and scores on individual dimensions. In the reliability evaluation, 39 of the 45 items showed prevalence-adjusted kappa greater than 0.60.

The aim was to investigate the prevalence of restless legs syndrome (RLS), fatigue and daytime sleepiness in a large cohort of patients affected by post polio syndrome (PPS) and their impact on patient health-related quality of life (HRQoL) compared with healthy subjects. PPS patients were evaluated by means of the Stanford Sleepiness Scale and the Fatigue Severity Scale (FSS). The Short Form Health Survey (SF-36) questionnaire was utilized to assess HRQoL in PPS. RLS was diagnosed when standard criteria were met. Age and sex matched healthy controls were recruited amongst spouses or friends of PPS subjects. A total of 66 PPS patients and 80 healthy controls were enrolled in the study. A significantly higher prevalence of RLS (P < 0.0005; odds ratio 21.5; 95% confidence interval 8.17-57) was found in PPS patients (PPS/RLS+ 63.6%) than in healthy controls (7.5%). The FSS score was higher in PPS/RLS+ than in PPS/RLS- patients (P = 0.03). A significant decrease of SF-36 scores, including the physical function (P = 0.001), physical role (P = 0.0001) and bodily pain (P = 0.03) domains, was found in PPS/RLS+ versus PPS/RLS- patients. Finally, it was found that PPS/RLS+ showed a significant correlation between International Restless Legs Scale score and FSS (P < 0.0001), as well as between International Restless Legs Scale score and most of the SF-36 items (physical role P = 0.0018, general health P = 0.0009, vitality P = 0.0022, social functioning P = 0.002, role emotional P = 0.0019, and mental health P = 0.0003). Our findings demonstrate a high prevalence of RLS in PPS, and that RLS occurrence may significantly influence the HRQoL and fatigue of PPS patients. A hypothetical link between neuroanatomical and inflammatory mechanisms in RLS and PPS is suggested. © 2014 EAN.

Using structural equation modeling to detect response shifts and true change in discrete variables: an application to the items of the SF-36.

The structural equation modeling (SEM) approach for detection of response shift (Oort in Qual Life Res 14:587-598, 2005. doi: 10.1007/s11136-004-0830-y ) is especially suited for continuous data, e.g., questionnaire scales. The present objective is to explain how the SEM approach can be applied to discrete data and to illustrate response shift detection in items measuring health-related quality of life (HRQL) of cancer patients. The SEM approach for discrete data includes two stages: (1) establishing a model of underlying continuous variables that represent the observed discrete variables, (2) using these underlying continuous variables to establish a common factor model for the detection of response shift and to assess true change. The proposed SEM approach was illustrated with data of 485 cancer patients whose HRQL was measured with the SF-36, before and after start of antineoplastic treatment. Response shift effects were detected in items of the subscales mental health, physical functioning, role limitations due to physical health, and bodily pain. Recalibration response shifts indicated that patients experienced relatively fewer limitations with "bathing or dressing yourself" (effect size d = 0.51) and less "nervousness" (d = 0.30), but more "pain" (d = -0.23) and less "happiness" (d = -0.16) after antineoplastic treatment as compared to the other symptoms of the same subscale. Overall, patients' mental health improved, while their physical health, vitality, and social functioning deteriorated. No change was found for the other subscales of the SF-36. The proposed SEM approach to discrete data enables response shift detection at the item level. This will lead to a better understanding of the response shift phenomena at the item level and therefore enhances interpretation of change in the area of HRQL.

HOOS was developed as an extension of the Western Ontario and McMaster Universities' Osteoarthritis Index questionnaire for measuring symptoms and functional limitations related to the hip(s) of patients with osteoarthritis. To determine the validity and reliability of the Thai version of the Hip disability and Osteoarthritis Outcome Score (HOOS) vis-à-vis hip osteoarthritis, the original HOOS was translated into a Thai version of HOOS, according to international recommendations. Patients with hip osteoarthritis (n = 57; 25 males) were asked to complete the Thai version of HOOS twice: once then again after a 3-week interval. The test-retest reliability was analyzed using the intraclass correlation coefficient (ICC). Internal consistencies were analyzed using Cronbach's alpha, while the construct validity was tested by comparing the Thai HOOS with the Thai modified SF-36 and calculating the Spearman's rank correlation coefficients. The Thai HOOS produced good reliability (i.e., the ICC was greater than 0.9 in all five subscales). All of the Cronbach's alpha showed that the Thai HOOS had high internal consistency (Cronbach's alpha greater than 0.8), especially for the pain and ADL subscales (0.89 and 0.90, respectively). The Spearman's rank correlation for all five subscales of the Thai HOOS had moderate correlation with the Bodily Pain subscale of the Thai SF-36. The pain subscale of the Thai HOOS had a high correlation with the Vitality and Social Function subscales of the Thai SF-36 (r = 0.55 and 0.54)-with which the symptom subscale had a moderate correlation. The Thai version of HOOS had excellent internal consistency, excellent test-retest reliability, and good construct validity. It can be used as a reliable tool for assessing quality of life for patients with hip osteoarthritis in Thailand.

Malnutrition is common in patients with hip fractures, and elderly patients with hip fractures lose functional independence and often fail to recover previous functional status. The aim of this study was to determine whether pre-fracture nutritional status predicts functional status of patients with hip fracture at discharge from acute hospitals. In the present multicenter prospective cohort study, pre-fracture nutritional status was assessed using the Mini Nutritional Assessment Short-Form (MNA-SF). At discharge from acute hospitals, functional status was evaluated using a functional independent measurement instrument (FIM). Subsequently, multiple regression analyses were performed using FIM as the dependent variable and MNA-SF as the independent variable. Among the 204 patients analyzed in the present study, the mean length of hospital stay was 26.2 ± 12.6 days, and according to MNA-SF assessments, 51 (25.0%) patients were malnourished, 98 (48.0%) were at risk of malnutrition, and 55 (27.0%) were well-nourished before fracture. At discharge, FIM scores were higher in patients who were well-nourished than in those who were malnourished or were at risk of malnutrition (p < 0.01). After adjustment for confounding factors, multiple regression analyses showed that MNA-SF was a significant independent predictor for FIM at discharge (well-nourished vs. malnourished, β = -0.86, p < 0.01). Pre-fracture nutritional status was a significant independent predictor for functional status at discharge during the acute phase, warranting early assessment of nutritional status and early intervention for successful postoperative rehabilitation.

The aim was to evaluate the cross-cultural validity of the Lupus Impact Tracker (LIT) in five European countries and to assess its acceptability and feasibility from the patient and physician perspectives. A prospective, observational, cross-sectional and multicentre validation study was conducted in clinical settings. Before the visit, patients completed LIT, Short Form 36 (SF-36) and care satisfaction questionnaires. During the visit, physicians assessed disease activity [Safety of Estrogens in Lupus Erythematosus National Assessment (SELENA)-SLEDAI], organ damage [SLICC/ACR damage index (SDI)] and flare occurrence. Cross-cultural validity was assessed using the Differential Item Functioning method. Five hundred and sixty-nine SLE patients were included by 25 specialists; 91.7% were outpatients and 89.9% female, with mean age 43.5 (13.0) years. Disease profile was as follows: 18.3% experienced flares; mean SELENA-SLEDAI score 3.4 (4.5); mean SDI score 0.8 (1.4); and SF-36 mean physical and mental component summary scores: physical component summary 42.8 (10.8) and mental component summary 43.0 (12.3). Mean LIT score was 34.2 (22.3) (median: 32.5), indicating that lupus moderately impacted patients' daily life. A cultural Differential Item Functioning of negligible magnitude was detected across countries (pseudo- R 2 difference of 0.01-0.04). Differences were observed between LIT scores and Physician Global Assessment, SELENA-SLEDAI, SDI scores = 0 (P < 0.035) and absence of flares (P = 0.004). The LIT showed a strong association with SF-36 physical and social role functioning, vitality, bodily pain and mental health (P < 0.001). The LIT was well accepted by patients and physicians. It was reliable, with Cronbach α coefficients ranging from 0.89 to 0.92 among countries. The LIT is validated in the five participating European countries. The results show its reliability and cultural invariability across countries. They suggest that LIT can be used in routine clinical practice to evaluate and follow patient-reported outcomes in order to improve patient-physician interaction. © The Author 2017.

Allogeneic hematopoietic stem-cell transplantation (alloHSCT) is physically and psychosocially demanding. Among transplant recipients, adolescent and young adults (AYA) represent a special group, as disease occurs early in life, resulting in the prospect of long survival time and high burden of alloHSCT sequelae. However, data focusing on AYA undergoing alloHSCT are rare. Data resulting from a prospective multicenter trial initially focusing on graft-versus-host disease (GvHD) after alloHSCT were reused to analyse the differences between AYA and elderly patients. In total, data of 205 alloHSCT recipients were evaluated. Patients completed the FACT-BMT, HAP, SF-36, 24-AM, LOT-R, BSSS, HADS, and GvHD questionnaires. Median age of AYA and non-AYA patients was 29 and 52 years. Using 24-AM-Test, evaluating personality traits, non-AYA reported to be more conscientious (p = 0.033). However, AYA described higher quality of life regarding physical role functioning (p = 0.001), physical functioning (p = 0.002), bodily pain (p = 0.023), and emotional role function (p = 0.027) in the SF-36. General health perception, vitality, social role functioning, and mental health were comparable among both groups. On HAP scale, AYA reported higher maximum (p = 0.003) and adjusted activity scores (p = 0.002), but showed similar restrictions regarding activity, self-supply, and self-determination. AYA represent a particular group characterized by higher physical well-being and activity scores, and significantly vary from non-AYA patients in psychosocial aspects. Studies covering distinctive features of AYA undergoing alloHSCT are warranted to improve awareness of the special needs of this group.

The aim of this study was to explore the relation between mothers' parenting stress and the functioning of the hypothalamic-pituitary-adrenal axis (HPAA), as expressed by daily salivary cortisol concentrations, in their children diagnosed with attention deficit hyperactivity disorder (ADHD). Seventy-five children aged 6-11 years diagnosed with ADHD predominant hyperactive-impulsive/combined (ADHD-HI/C, N = 49) and inattentive symptoms (ADHD-I, N = 26) and 45 healthy peers and their mothers participated in the study. Μothers completed measures assessing their children's ADHD status, perceived parenting stress (Parenting Stress Index - Short Form, PSI-SF), mothers' symptoms of psychopathology, social support and socioeconomic status. Children's salivary cortisol samples were collected at six different time points on a single day. Mothers of children with ADHD-HI/C reported higher levels of parenting stress than mothers of children with ADHD-I and controls. All PSI-SF subscales showed significant associations with children's cortisol awakening response (CAR) in both ADHD groups, with the exception of the parental distress subscale in the ADHD-I group. In both ADHD groups, the parent-child dysfunctional interaction subscale, the difficult child subscale and the PSI total score were significantly associated with children's CAR. An interrelation is revealed between mothers' high levels of parenting stress and HPAA functioning in children with ADHD. In this population, CAR has been identified as a sensitive peripheral measure of HPAA functioning in children. Lay summaryThis study showed that in families of children diagnosed with ADHD, there is a complex relation between the mothers' high levels of parenting stress and children's atypical hypothalamic-pituitary-adrenal axis functioning.

Objectives LupusPRO has shown good measurement properties as a disease-specific patient-reported outcome tool in systemic lupus erythematosus (SLE). For the purpose of clinical trials, the version 1.7 (v1.7) domain of Pain-Vitality was separated into distinct Pain, Vitality and Sleep domains in v1.8, and the psychometric properties examined. Methods A total of 131 consecutive SLE patients were self-administered surveys assessing fatigue (FACIT, SF-36), pain (Pain Inventory, SF-36), insomnia (Insomnia Severity Index), emotional health (PHQ-9, SF-36) and quality of life (SF-36, LupusPRO) at routine care visits. Internal consistency reliability (ICR) for each domain was obtained using Cronbach's alpha. The convergent construct validity of LupusPRO domains with corresponding SF-36 domains or tools were tested using Spearman correlation. Varimax rotations were conducted to assess factor structures of the LupusPRO v1.8. Results Mean (SD) age was 40.04 (14.10) years. Scores from the LupusPRO-Sleep domain strongly correlated with insomnia scores, while LupusPRO-Vitality correlated strongly with fatigue (FACIT) and SF-36 vitality. The LupusPRO-Pain domain correlated strongly with pain (SF36 Bodily-Pain, Pain Inventory) scores. Similarly, the LupusPRO domains of Physical and Emotional Health had significant correlations with corresponding SF-36 domains. The ICR for HRQoL and non-HRQoL were 0.96 and 0.81. LupusPRO (domains HRQoL and QoL) scores correlated with disease activity. Principal component analysis included seven factor loadings presenting for the HRQOL subscales (combined Sleep, Vitality, and Pain), and three factors for the NHRQoL (Combined Coping and Social Support). Conclusions LupusPRO v1.8 (including its Sleep, Vitality, and Pain domains) has acceptable reliability and validity. Use of LupusPRO as an outcome measure in clinical trials would facilitate responsiveness assessment.

The LupusQoL© questionnaire is a disease-specific health related quality of life (HRQOL) instrument for adults with systemic lupus erythematosus (SLE). The Short Form-36 (SF-36) is a generic instrument that captures the physical, psychological, and social impact. We conducted a descriptive study of women aged ≥ 18 years attending our Lupus Clinic. HRQOL was assessed by applying the LupusQoL© and SF-36. Lupus activity was measured using the Mexican Systemic Lupus Erythematosus Disease Activity Index (Mex-SLEDAI) and chronic damage using the Systemic Lupus Collaborative Clinics Damage Index (SDI). Data were analyzed using descriptive statistics, the chi-square test and Pearson's product moment correlation coefficient. A total of 127 patients were included with a mean age of 40.5 ± 12.6 years. The mean disease duration was 8.2 ± 5.6 years, the mean disease activity score was 2.4 ± 3.0, and the mean SDI score 0.77 ± 1.06. The mean SF-36 score was 58.1 ± 21.1 and the mean LupusQoL© score was 69 ± 22.7. The correlation between global scores of the SF-36 and LupusQoL© was rho = 0.73 (p < 0.001). The correlation between lupus disease activity and the SF-36 and the LupusQoL© was -0.26 (p = 0.003) and -0.25 (p = 0.004), respectively. The correlation between the SDI and the SF-36 and the LupusQoL© was -0.28 (p = 0.001) and -0.38 (p < 0.0001), respectively. In conclusions: both LupusQoL© and SF-36 were useful instruments in assessing HRQOL in Mexican lupus female patients. The usefulness of the LupusQoL© should be evaluated in lupus patients with moderate to severe disease activity.

In epidemiological surveillance of mental health there is good reason to also include scales that measure the presence of well-being rather than merely symptoms of ill health. The Mental Health Continuum-Short Form (MHC-SF) is a self-reported scale to measure emotional, psychological and social well-being and conduct categorical diagnosis of positive mental health. This particular instrument includes the three core components of the World Health Organization's definition of mental health and had previously not been psychometrically evaluated on adolescents in China. In total 5,399 students (51.1% female) from schools in the urban areas of Weifang in China were included in the study (mean age = 15.13, SD = 1.56). Participants completed a comprehensive questionnaire with several scales, among them the MHC-SF. Statistical analyses to evaluate reliability, structural validity, measurement invariance, presence of floor and ceiling effects and to some extent external validity of the MHC-SF were carried out. The Cronbach's α coefficients for sub-scales as well as the total scale were all above 0.80 indicating good reliability. Confirmative factor analysis confirmed the three-dimensional structure of the Chinese version of MHC-SF and supported the configural and metric invariance across gender and age. Noteworthy ceiling effects were observed for single items and sub-scales although not for the total scale. More importantly, observed floor effects were negligible. The stronger correlation found between MHC-SF and Minneapolis-Manchester Quality of Life Instrument (as measure of positive mental health) than between MHC-SF and Hospital Anxiety Depression Scale (as measure of mental illness and distress) yielded support for external validity. In conclusion, the main findings of this study are in line with studies from other countries that evaluated the psychometric properties of the MHC-SF and show that this instrument, that includes the three core components of the WHO definition of mental health, is useful in assessing positive adolescent mental health also in China.

We report new Herschel observations of 25 z {approx_equal} 4.8 extremely luminous optically selected active galactic nuclei (AGNs). Five of the sources have extremely large star-forming (SF) luminosities, L{sub SF}, corresponding to SF rates (SFRs) of 2800-5600 M{sub Sun} yr{sup -1} assuming a Salpeter initial mass function. The remaining sources have only upper limits on their SFRs, but stacking their Herschel images results in a mean SFR of 700 {+-} 150 M{sub Sun} yr{sup -1}. The higher SFRs in our sample are comparable to the highest observed values so far at any redshift. Our sample does not contain obscured AGNs,more » which enables us to investigate several evolutionary scenarios connecting supermassive black holes and SF activity in the early universe. The most probable scenario is that we are witnessing the peak of SF activity in some sources and the beginning of the post-starburst decline in others. We suggest that all 25 sources, which are at their peak AGN activity, are in large mergers. AGN feedback may be responsible for diminishing the SF activity in 20 of them, but is not operating efficiently in 5 others.« less

Breath in the technoscientific imaginary

PubMed Central

Rose, Arthur

2016-01-01

Breath has a realist function in most artistic media. It serves to remind the reader, the viewer or the spectator of the exigencies of the body. In science fiction (SF) literature and films, breath is often a plot device for human encounters with otherness, either with alien peoples, who may not breathe oxygen, or environments, where there may not be oxygen to breathe. But while there is a technoscientific quality to breath in SF, especially in its attention to physiological systems, concentrating on the technoscientific threatens to occlude other, more affective aspects raised by the literature. In order to supplement the tendency to read SF as a succession of technoscientific accounts of bodily experience, this paper recalls how SF texts draw attention to the affective, non-scientific qualities of breath, both as a metonym for life and as a metaphor for anticipation. Through an engagement with diverse examples from SF literature and films, this article considers the tension between technoscientific and affective responses to breath in order to demonstrate breath's co-determinacy in SF's blending of scientific and artistic discourses.

Modeling galaxy formation and evolution is critically depending on star formation (SF). Since cosmological and galaxy-scale simulations cannot resolve the spatial and density scales on which SF acts, a large variety of methods are developed and applied over the last decades. Nonetheless, we are still in the test phase how the choice of parameters affects the models and how they agree with observations.As a simple ansatz, recipes are based on power-law SF dependences on gas density as justified by gas cooling and collapse timescales. In order to prevent SF spread throughout the gas, temperature and density thresholds are also used, although gas dynamical effects, like e.g. gas infall, seem to trigger SF significantly.The formed stars influence their environment immediately by energetic and materialistic feedback. It has been experienced in numerical models that supernova typeII explosions act with a too long time delay to regulate the SF, but that winds and ionizing radiation by massive stars must be included. The implementation of feedback processes, their efficiencies and timescales, is still in an experimental state, because they depend also on the physical state of the surrounding interstellar medium (ISM).Combining a SF-gas density relation with stellar heating vs. gas cooling and taking the temperature dependence into account, we have derived an analytical expression of self-regulated SF which is free of arbitrary parameters. We have performed numerical models to study this recipe and different widely used SF criteria in both, particle and grid codes. Moreover, we compare the SF behavior between single-gas phase and multi-phase treatments of the ISM.Since dwarf galaxies (DGs) are most sensitive to environmental influences and contain only low SF rates, we explore two main affects on their models: 1. For external effects we compare SF rates of isolated and ram-pressure suffering DGs. Moreover, we find a SF enhancement in tidal-tail DGs by the compressive tidal field. 2. Because of locally low SF rates we compare the stellar feedback of a mostly assumed but only fractionally occupied stellar initial mass function with a bottom-heavy one.

To assess the health status of patients before and after breast reduction surgery and to make comparisons with the health status of women in the general population. Postal questionnaire survey sent to patients before and six months after surgery. The three plastic surgery departments in the Oxford Regional Health Authority, during April to August 1993. 166 women (over the age of 16 years) referred for breast reduction; scores from the "short form 36" (SF-36) health questionnaire completed by women in the 1991-2 Oxford healthy life survey. Health status of breast reduction patients before and after surgery as assessed by the SF-36, the 28 item general health questionnaire, and Rosenberg's self esteem scale; comparisons between the health status of breast reduction patients and that of women in the general population; outcome of surgery as assessed retrospectively by patients. Differences between the health status of breast reduction patients and that of women in the general population were detected by the SF-36 both before and after surgery. Breast reduction surgery produced substantial change in patients' physical, social, and psychological function. The proportion of cases of possible psychiatric morbidity according to the general health questionnaire fell from 41% (22/54) before surgery to 11% (6/54) six months after treatment. Eighty six per cent (50/58) of patients expressed great satisfaction with the surgical result postoperatively. The study provides empirical evidence that supports the inclusion of breast reduction surgery in NHS purchasing contracts.

Introduction: This article describes the procedures used in the PROMIS® Smoking Initiative for the development and evaluation of item banks, short forms (SFs), and computerized adaptive tests (CATs) for the assessment of 6 constructs related to cigarette smoking: nicotine dependence, coping expectancies, emotional and sensory expectancies, health expectancies, psychosocial expectancies, and social motivations for smoking. Methods: Analyses were conducted using response data from a large national sample of smokers. Items related to each construct were subjected to extensive item factor analyses and evaluation of differential item functioning (DIF). Final item banks were calibrated, and SF assessments were developed for each construct. The performance of the SFs and the potential use of the item banks for CAT administration were examined through simulation study. Results: Item selection based on dimensionality assessment and DIF analyses produced item banks that were essentially unidimensional in structure and free of bias. Simulation studies demonstrated that the constructs could be accurately measured with a relatively small number of carefully selected items, either through fixed SFs or CAT-based assessment. Illustrative results are presented, and subsequent articles provide detailed discussion of each item bank in turn. Conclusions: The development of the PROMIS smoking item banks provides researchers with new tools for measuring smoking-related constructs. The use of the calibrated item banks and suggested SF assessments will enhance the quality of score estimates, thus advancing smoking research. Moreover, the methods used in the current study, including innovative approaches to item selection and SF construction, may have general relevance to item bank development and evaluation.

Light chain (AL) amyloidosis is a rare disease associated with significant, irreversible organ dysfunction and high case fatality. An observational study was conducted to assess health-related quality of life (HRQoL) in patients treated for AL amyloidosis between 1994 and 2014 with both high dose melphalan and stem cell transplantation (HDM/SCT) or non-SCT chemotherapy regimens. The SF-36v1 ® Health Survey (SF-36) was administered to assess HRQoL during clinic visits. Analysis of variance was used to compare pre- and post-treatment HRQoL within each treatment group to an age- and gender-adjusted general population (GP) normative sample. Cox proportional hazard models were fit to examine associations between pre-treatment levels of HRQoL and mortality within 1 and 5 years after initiating specific treatment regimens (HDM/SCT: n = 402; non-SCT chemotherapy regimens: n = 172). Among patients who received HDM/SCT, there were significant improvements following treatment in vitality, social functioning, role-emotional and mental health. Worse pre-treatment SF-36 physical component scores were associated with a greater risk of mortality in both treatment groups and follow-up periods (P ≤ 0·005 for both). [Correction added on 20 October 2017, after first online publication: This P value has been corrected]. Using HRQoL assessments in every physician visit or treatment may provide valuable insights for treating rare conditions like AL amyloidosis. © 2017 The Authors.

To evaluate the impact of a lifetime history of anorexia nervosa (AN) on current quality of life (QoL) and eating disorder (ED) symptomatology. 3,034 participants from a randomly selected sample of households in the Australian population were interviewed for current ED symptoms and QoL (SF-36). 89 participants (2.9 %) reported a history of AN, 73 of whom were female. These participants scored lower on six of the eight subscales on the SF-36, including all of the mental health subscales, and were more likely to report binge eating and extreme weight or shape concerns than participants who did not report a history of AN. On the other hand, participants who reported a history of AN were less likely to be overweight. None of the participants who reported a history of AN met current criteria for AN; however, one met criteria for bulimia nervosa non-purging subtype and four met criteria for binge eating disorder. The endorsement of current ED symptoms was found to moderate the impact of a history of AN on scores of the social functioning and role limitations due to emotional health SF-36 subscales, such that participants who reported a history of AN scored lower on these subscales if they also reported current ED symptoms. A history of AN has a deleterious impact on current QoL, despite remittance from the disorder. This may be explained in part by the presence of certain ED symptoms, including objective binge eating and the persistence of extreme weight and shape concerns.

The present project has been developed because of the desire to unify the research lines in the A.S.I. ‘Medicine & Biotechnology’ area into one research line that could satisfy the interests of all of the collaborative groups and at the same time could pursue a relevant social goal. A 6 month feasibility study (SF) called MoMa was carried out in the ASI framework. During the SF the know-how and the tools already available in the national scientific community have been assessed, selected and evaluated even with the important contribution of Small and Medium-size Enterprises (SME) and of Italian industries already involved in Space Research. As result of the SF MoMa, all of the participants decided to combine all the efforts together and define, with all the know-how and the available technologies, one strategic topic, the “Aging” with a special attention to the Quality of Life (QoL). The space environment is a unique laboratory to study the reaction of living organisms (especially humans) to microgravity and cosmic radiation. The study of the effects of these two variables at the molecular and cellular levels will shed light on the response of cells and living organisms to adverse stimulations that are always present even on Earth and will help us able to develop the best strategies to protect the organisms from the progressive structural and functional decline related to Aging. Relevant spin-offs on Earth and also relevant industrial applications are the expected outputs of this project.

This study was planned to investigate the relationship between musculoskeletal problems, depression, and quality of life in students preparing for university entrance exams. A total of 180 students were included in the study, 104 were female (57.77%), and 76 were male (42.22%). Students were reached through the cram schools ("dershane") in Denizli. Musculoskeletal system problems, depression status, and quality of life were determined with the Musculoskeletal-Postural Discomfort Scale (MDS), Boratav Depression Screen Scale (Bordepta), and Short Form-36 (SF-36), respectively. Demographic data, daily study, and sleep duration were also recorded. Students have moderate musculoskeletal discomfort. Musculoskeletal disorders and depressive symptoms are more observed in female students than male students ( P = 0.000). The SF-36 results were significantly negatively correlated with the MDS and Bordepta scores. A significant positive correlation was found between musculoskeletal disorders and depression status (r = 0.351, P = 0.000). Sleep duration was negatively correlated with the MDS and Bordepta (r = -0.209, P = 0.005; r = -0.148, P = 0.047, respectively) and positively correlated with the SF-36 role limitation/emotional and social functioning subscales (r = 0.225, P = 0.002 and r = 0.191, P = 0.010 respectively). Musculoskeletal problems and depression status negatively affects general health status especially in female students who are preparing for university entrance examinations. Students should be informed about musculoskeletal problems by healthcare professionals and the study room, tables, and chairs should be arranged ergonomically. Further studies might be determined that why musculoskeletal disorders and depression status are more widely among female students.

The number of patients receiving total knee arthroplasty (TKA) has been rising every year due to the aging population and the obesity epidemic. Post-operative rehabilitation is important for the outcome of TKA. A series of 34 patients who underwent primary unilateral TKA was retrospectively collected and divided into either exercise group (n = 16) and control group (n = 18). The exercise group underwent a 24-week course of circuit training beginning 3 months after total knee arthroplasty (TKA). The effect of circuit training on TKA patients in terms of motion analysis, muscle strength testing, Knee injury and Osteoarthritis Outcomes Score (KOOS) questionnaire and patient-reported outcome measurement Short-Form Health Survey (SF-36) at the pre-operation, pre-exercise, mid-exercise, and post-exercise. Motion analysis revealed the stride length, step velocity, and excursion of active knee range of motion significantly improved in the exercise group when compared to those in the control group. KOOS questionnaire showed a greater improvement in pain, ADL, and total scores in the exercise group. The SF-36 questionnaire revealed a significant improvement in general health, bodily pain, social function, and physical components score in the exercise group. The post-operative circuit training intervention can facilitate recovery of knee function and decrease the degree of pain in the TKA and might be considered a useful adjunct rehabilitative modality. The ultimate influence of circuit training on TKA needs further a prospective randomized clinical trial study and long-term investigation. NCT02928562.

Some treatment modalities may cause losses in patients' life comfort because of the treatment process. Our aim is to determine the effects of thoracic surgery operations on patients' quality of life. This is a multicenter and prospective study. A hundred patients, who had undergone posterolateral thoracotomy (PLT) and/or lateral thoracotomy (LT), were included in the study. A quality of life questionnaire (SF-36) was used to determine the changes in life comfort. SF-36 was performed before the operation, on the first month, third month, sixth month and twelfth month after the operation. Seventy-two percent (n = 72) of the patients were male. PLT was performed in 66% (n = 66) of the patients, and LT was performed in 34% (n = 34) of the patients. The types of resections in patients were pneumonectomy in four patients, lobectomy in 59 patients and wedge resection in 11 patients. No resection was performed in 26 patients. Thoracotomy caused deteriorations in physical function (PF), physical role (RP), bodily pain (BP), health, vitality and social function scores. The deteriorations observed in the third month improved in the sixth and twelfth months. The PF, RP, BP and MH scores of the patients with lung resection were much more worsened compared with the patients who did not undergo lung resection. Thoracic surgery operations caused substantial dissatisfaction in life comfort especially in the third month postoperatively. The worsening in physical function, physical role, pain and mental health is much more in patients with resection compared with the patients who did not undergo resection. © 2014 John Wiley & Sons Ltd.

Quantification of quality of life (QoL) related to disease severity is important in patients with atopic eczema (AE), because the assessment provides additional information to the traditional objective clinical scoring systems. To measure health-related QoL (HRQoL) in patients with AE; to analyse discriminant, divergent and convergent validity by examining the association between various QoL methods; and to examine the association between disease severity assessed by an objective Severity Scoring of Atopic Dermatitis (SCORAD) and QoL. HRQoL was assessed at two visits at a 6-monthly interval in 101 patients with AE and 30 controls with one dermatology-specific questionnaire [Dermatology Life Quality Index (DLQI) or Children's DLQI (CDLQI)], one generic instrument (SF-36) and three visual analogue scales (VASs) of severity and pruritus. Objective SCORAD was used to measure disease severity. Patients with AE had significantly lower QoL than healthy controls and the general population. DLQI /CDLQI, pruritus, and patient and investigator overall assessment of eczema severity were significantly (P < 0.0001) and positively correlated with SCORAD, while the generic questionnaire showed only poor correlation. A gender difference was found for the mental component score of SF-36 (P = 0.019). AE has an impact on HRQoL. Patients' mental health, social functioning and role emotional functioning seem to be more affected than physical functioning. A simple VAS score of patients' assessment of disease severity showed the highest and most significant correlations with most of the HRQoL methods used. There is evidence to support the ability of patients with AE to make an accurate determination of their disease severity and QoL.

Superfamily 1 and Superfamily 2 helicases, two of the largest helicase protein families, play vital roles in many biological processes including replication, transcription and translation. Study of helicase proteins in the model microorganisms of archaea have largely contributed to the understanding of their function, architecture and assembly. Based on a large phylogenomics approach, we have identified and classified all SF1 and SF2 protein families in ninety five sequenced archaea genomes. Here we developed an online webserver linked to a specialized protein database named ARCPHdb to provide access for SF1 and SF2 helicase families from archaea. ARCPHdb was implemented using MySQL relational database. Web interfaces were developed using Netbeans. Data were stored according to UniProt accession numbers, NCBI Ref Seq ID, PDB IDs and Entrez Databases. A user-friendly interactive web interface has been developed to browse, search and download archaeal helicase protein sequences, their available 3D structure models, and related documentation available in the literature provided by ARCPHdb. The database provides direct links to matching external databases. The ARCPHdb is the first online database to compile all protein information on SF1 and SF2 helicase from archaea in one platform. This database provides essential resource information for all researchers interested in the field. Copyright © 2016 Elsevier Ltd. All rights reserved.

The objective of this study is to compare the quality of life (QOL) outcomes between laparoscopic radical prostatectomy (LRP) and robot-assisted radical prostatectomy (RARP). Between July 2007 and July 2013, 229 patients with localized prostate cancer underwent LRP while 105 patients with localized prostate cancer underwent RARP between December 2012 and August 2014. We evaluated their QOL using the 8-item Short-Form Health Survey (SF-8) and Expanded Prostate Cancer Index of Prostate (EPIC) questionnaires at preoperative and at postoperative 3, 6 and 12 months. In the LRP and RARP groups, over 80 and 90% of patients answered questionnaires at each follow-up time, respectively. At baseline QOL of EPIC and SF-8, there was no significant difference between LRP and RARP groups. At postoperative 3 months, Physical and Mental Components of SF-8 and Urinary Summary (U), all Urinary Subscales, Sexual Function and Bowel Function of EPIC showed significantly better scores in RARP group than in LRP group. At postoperative 6 and 12 months, there were no differences between LRP and RARP groups in terms of all QOL scores. RARP group showed better scores in SF-8 as well as urinary and sexual function of EPIC at postoperative-3 months. These differences disappeared at postoperative 6 and 12 months.

The GRB2-associated binder 1 (GAB1) docking/scaffold protein is a key mediator of the MET-tyrosine kinase receptor activated by hepatocyte growth factor/scatter factor (HGF/SF). Activated MET promotes recruitment and tyrosine phosphorylation of GAB1, which in turn recruits multiple proteins and mediates MET signaling leading to cell survival, motility, and morphogenesis. We previously reported that, without its ligand, MET is a functional caspase target during apoptosis, allowing the generation of a p40-MET fragment that amplifies apoptosis. In this study we established that GAB1 is also a functional caspase target by evidencing a caspase-cleaved p35-GAB1 fragment that contains the MET binding domain. GAB1 is cleaved by caspases before MET, and the resulting p35-GAB1 fragment is phosphorylated by MET upon HGF/SF binding and can interact with a subset of GAB1 partners, PI3K, and GRB2 but not with SHP2. This p35-GAB1 fragment favors cell survival by maintaining HGF/SF-induced MET activation of AKT and by hindering p40-MET pro-apoptotic function. These data demonstrate an anti-apoptotic role of caspase-cleaved GAB1 in HGF/SF-MET signaling. PMID:22915589

A major challenge in the diagnosis and treatment of brain tumors is tissue heterogeneity leading to mixed treatment response. Additionally, they are often difficult or at very high risk for biopsy, further hindering the clinical management process. To overcome this, novel advanced imaging methods are increasingly being adapted clinically to identify useful noninvasive biomarkers capable of disease stage characterization and treatment response prediction. One promising technique is called functional diffusion mapping (fDM), which uses diffusion-weighted imaging (DWI) to generate parametric maps between two imaging time points in order to identify significant voxel-wise changes in water diffusion within the tumor tissue. Here we introduce serial functional diffusion mapping (sfDM), an extension of existing fDM methods, to analyze the entire tumor diffusion profile along the temporal course of the disease. sfDM provides the tools necessary to analyze a tumor data set in the context of spatiotemporal parametric mapping: the image registration pipeline, biomarker extraction, and visualization tools. We present the general workflow of the pipeline, along with a typical use case for the software. sfDM is written in Python and is freely available as an open-source package under the Berkley Software Distribution (BSD) license to promote transparency and reproducibility.

Immunoglobulin superfamily proteins in Caenorhabditis elegans.

PubMed

Teichmann, S A; Chothia, C

2000-03-10

The predicted proteins of the genome of Caenorhabditis elegans were analysed by various sequence comparison methods to identify the repertoire of proteins that are members of the immunoglobulin superfamily (IgSF). The IgSF is one of the largest families of protein domain in this genome and likely to be one of the major families in other multicellular eukaryotes too. This is because members of the superfamily are involved in a variety of functions including cell-cell recognition, cell-surface receptors, muscle structure and, in higher organisms, the immune system. Sixty-four proteins with 488 I set IgSF domains were identified largely by using Hidden Markov models. The domain architectures of the protein products of these 64 genes are described. Twenty-one of these had been characterised previously. We show that another 25 are related to proteins of known function. The C. elegans IgSF proteins can be classified into five broad categories: muscle proteins, protein kinases and phosphatases, three categories of proteins involved in the development of the nervous system, leucine-rich repeat containing proteins and proteins without homologues of known function, of which there are 18. The 19 proteins involved in nervous system development that are not kinases or phosphatases are homologues of neuroglian, axonin, NCAM, wrapper, klingon, ICCR and nephrin or belong to the recently identified zig gene family. Out of the set of 64 genes, 22 are on the X chromosome. This study should be seen as an initial description of the IgSF repertoire in C. elegans, because the current gene definitions may contain a number of errors, especially in the case of long sequences, and there may be IgSF genes that have not yet been detected. However, the proteins described here do provide an overview of the bulk of the repertoire of immunoglobulin superfamily members in C. elegans, a framework for refinement and extension of the repertoire as gene and protein definitions improve, and the basis for investigations of their function and for comparisons with the repertoires of other organisms.

Role overload, pain and physical dysfunction in early rheumatoid or undifferentiated inflammatory arthritis in Canada

PubMed Central

2012-01-01

Background Inflammatory arthritis impairs participation in societal roles. Role overload arises when the demands by a given role set exceed the resources; time and energy, to carry out the required tasks. The present study examines the association between role overload and disease outcomes in early inflammatory arthritis (EIA). Methods Patients (n = 104) of 7.61 months mean duration of inflammatory arthritis completed self-report questionnaires on sociodemographics, disease characteristics and role overload. Pain was assessed using the Short Form McGill Pain Questionnaire (MPQ) and physical functioning was measured with the Medical Outcomes Study Short Form 36 (SF-36) physical functioning score. Role overload was measured by the Role Overload Scale. Patients indicated the number of social roles they occupied from a total of the three typical roles; marital, parental and paid work. Results Participants’ mean age was 56 years and 70.2% were female. Role overload was not correlated to the number of social roles, however, it was positively associated with pain (p = 0.004) and negatively associated with physical functioning (p = 0.001). On multivariate analysis, role overload was negatively associated with physical functioning after controlling for the relevant sociodemographic variables. Conclusion This study identifies a possible reciprocal relationship between role overload and physical functioning in patients with EIA. PMID:22554167

To measure health-related and olfaction-related quality of life (QoL) in patients with permanent, severe hyposmia or functional anosmia. A case study in a university ENT department of patients with severe olfactory dysfunction defined by Sniffin' Sticks olfactory test kit with a score for odor threshold, discrimination, and identification (TDI) < 20 and a dysfunction lasting longer than 6 months. Assessment of QoL by using the SF-36 Health Survey questionnaire and the Questionnaire for Olfactory Dysfunction (QOD). A total of 958 patients were tested for smell disturbances from 1999 to 2009. Surveys were mailed to 527 patients who fulfilled the inclusion criteria; 280 (53%) returned completed surveys. All SF-36 domains in severely hyposmic and anosmic patients were lower than in the German normal population. Lower SF-36 QoL was found for some domains in female patients, older patients, and hyposmic patients (P < .05 for all groups). Based on the QOD, women showed more parosmia, and anosmic patients had more olfactory-related impairment (P < .05 for both); in general, higher olfactory impairment and higher parosmia score measured by QOD correlated with lower TDI values (all P < .05). Multivariate analysis revealed, for SF-36 domains, the following independent risk factors: female sex was a risk factor for bodily pain; higher age was a risk factor for physical functioning and role, bodily pain, and general health; hyposmia was a risk factor for bodily pain and mental health; QOD QoL was a risk factor for all SF-36 scales; and QOD parosmia was a risk factor for physical role (all P < .05). QoL is severely impaired in patients with chronic severe hyposmia or anosmia. The QOD allows a more olfaction-specific assessment of QoL than the SF-36 instrument.

Health-related quality of life (HRQOL) in patients with fibromyalgia (FM) is lower than in patients with other chronic diseases and the general population. Although various factors affect HRQOL, no study has examined a structural equation model of HRQOL as an outcome variable in FM patients. The present study assessed relationships among physical function, social factors, psychological factors, and HRQOL, and the effects of these variables on HRQOL in a hypothesized model using structural equation modeling (SEM). HRQOL was measured using SF-36, and the Fibromyalgia Impact Questionnaire (FIQ) was used to assess physical dysfunction. Social and psychological statuses were assessed using the Beck Depression Inventory (BDI), the State-Trait Anxiety Inventory (STAI), the Arthritis Self-Efficacy Scale (ASES), and the Social Support Scale. SEM analysis was used to test the structural relationships of the model using the AMOS software. Of the 336 patients, 301 (89.6%) were women with an average age of 47.9±10.9 years. The SEM results supported the hypothesized structural model (χ2 = 2.336, df = 3, p = 0.506). The final model showed that Physical Component Summary (PCS) was directly related to self-efficacy and inversely related to FIQ, and that Mental Component Summary (MCS) was inversely related to FIQ, BDI, and STAI. In our model of FM patients, HRQOL was affected by physical, social, and psychological variables. In these patients, higher levels of physical function and self-efficacy can improve the PCS of HRQOL, while physical function, depression, and anxiety negatively affect the MCS of HRQOL.

2017-10-01

Healthcare professional schools across the world are implementing near-peer tutoring (NPT) programs owing to numerous benefits to both tutors and tutees. This study determined whether higher attendance at NPT sessions led to improvements in course grades for high and low performing students. Fourth-year medical students used the USMLE Step 1 question format to tutor first-year medical students during the second half of the Structure and Function (SF) module, i.e., SF2. Attendance was recorded and students were accordingly divided into three groups: high, moderate, and low-no attendance. Students' performances in SF1 and SF2 were compared using Student's t-test. Differences among the three groups were analyzed using ANOVA and Scheffé post hoc test (P< 0.05). Students who earned 70-79% (C) in SF1 were further examined on the basis of their attendance rate and performance in SF2. Those who attended three or more sessions completed a survey evaluating the NPT program. Course grades were significantly higher in SF2 than SF1 for all students, regardless of attendance rate. However, students who received a C grade in SF1 and had high or moderate attendance improved significantly in their SF2 course grade. Most students agreed that the NPT program was valuable and they evaluated the tutors highly. They also agreed that NPT prepared them for course exams and Step 1, but did not reduce anxiety and stress about Step 1. The positive effect of the NPT program resulted in its expansion to include all first-year modules. Clin. Anat. 30:922-928, 2017. © 2017 Wiley Periodicals, Inc. © 2017 Wiley Periodicals, Inc.

There is a paucity of research in the area of social support and psychological well-being among people with gender dysphoria. The present study aimed to investigate levels of social support among individuals with gender dysphoria compared with a matched control group. It also aimed to examine the relationship between social support and psychological well-being. Participants were 103 individuals diagnosed with gender dysphoria (according to ICD-10 criteria) attending a national gender identity clinic and an age- and gender-matched nonclinical control group recruited via social networking websites. All participants completed measures of social support (Multidimensional Scale of Perceived Social Support, MSPSS), psychopathology (Symptom Checklist 90 Revised, SCL), quality of life (Short Form 36 version 2, SF), and life satisfaction (Personal Wellbeing Index, PWI). Trans women reported significantly lower MSPSS total and MSPSS family scores compared with control women, although these differences in levels of social support were no longer significant when SCL depression was controlled for. No significant differences were found between trans men and any other group. MSPSS scores did not significantly predict SCL subscales but did predict both SF subscales and PWI total scores. Trans women perceived themselves to be lacking social support. Given that social support is beneficial to quality of life and life satisfaction in those with gender dysphoria, this is of great concern. Though these findings have been derived from correlational results, extended research may highlight the value of clinicians helping trans women to seek out and maintain social support. Additionally, efforts could be made to educate and challenge attitudes of nontrans people towards those with gender dysphoria. © 2014 International Society for Sexual Medicine.

The Memorial Symptom Assessment Scale Short Form (MSAS-SF) is a widely used symptom assessment instrument. Patients who self-complete the MSAS-SF have difficulty following the two-part response format, resulting in incorrectly completed responses. We describe modifications to the response format to improve useability, and rational scoring rules for incorrectly completed items. The modified MSAS-SF was completed by 311 women in our Peer and Nurse support Trial to Assist women in Gynaecological Oncology; the PeNTAGOn study. Descriptive statistics were used to summarise completion of the modified MSAS-SF, and provide symptom statistics before and after applying the rational scoring rules. Spearman's correlations with the Functional Assessment for Cancer Therapy-General (FACT-G) and Hospital Anxiety and Depression Scale (HADS) were assessed. Correct completion of the modified MSAS-SF items ranged from 91.5 to 98.7%. The rational scoring rules increased the percentage of useable responses on average 4% across all symptoms. MSAS-SF item statistics were similar with and without the scoring rules. The pattern of correlations with FACT-G and HADS was compatible with prior research. The modified MSAS-SF was useable for self-completion and responses demonstrated validity. The rational scoring rules can minimise loss of data from incorrectly completed responses. Further investigation is recommended.

Migraine headaches have been shown to have substantial personal and societal implications. Health-related quality of life (HRQOL) assessments of migraineurs have been used to monitor and evaluate patient- and population-based outcomes, and to evaluate effectiveness and responsiveness to treatment. In this paper, we test a new, even shorter generic health survey, the SF-8 Health Survey (SF-8), an alternate form that uses one question to measure each of the eight SF-36 Health Survey (SF-36) domains, in a sub-sample of migraine sufferers. Data from 7557 participants surveyed via the Internet and mail were used to document the burden of migraine on HRQOL and to compare the relative burden of migraine with other chronic conditions using the SF-8. Migraineurs' HRQOL is similar to those with congestive heart failure, hypertension and diabetes, and is better than those with depression. Migraine sufferers experience better physical health and worse mental health (MH) than those with osteoarthritis. Results support prior research indicating that the burden of migraine on functional health and well-being is considerable and comparable to other chronic conditions known to have substantial impact on HRQOL. The SF-8 may provide a more practical and efficient method to describe the burden of migraine in population studies.

This study used variables proposed in social cognitive career theory (SCCT) to focus the evaluation of a research curriculum at the Cleveland Clinic Lerner College of Medicine of Case Western Reserve University (CCLCM). Eight cohorts of CCLCM medical students completed a web-based version of the six-scale Clinical Research Appraisal Inventory-Short Form (CRAI-SF) items at matriculation (n = 128) or graduation (n = 111) during 2009-2013. Parametric statistics were used to compare CRAI-SF scales to domains proposed in SCCT: trainees' characteristics (gender, training level, advanced degree), career interests, career intentions (medical specialty), and performance (peer-reviewed publications and required thesis topic). A number of lessons emerged in using theory to frame the evaluation of a complex educational program. Graduates rated their research self-efficacy significantly higher on all six CRAI-SF scales with large effect sizes (>.90) on five scales (Conceptualizing a Study, Study Design and Analysis, Responsible Research Conduct, Collaborating with Others, and Reporting a Study). Women and men did not have significantly different scores on CRAI-SF scales (p > .05), suggesting that the research program provides adequate supports for women students. Most thesis projects addressed clinical (36.9 %, n = 41) or translational (34.2 %, n = 38) research topics. The CRAI-SF discriminated between medical school matriculates and graduates, suggesting that research self-efficacy increases with mastery experiences. No significant relationships occurred between CRAI-SF scores and graduates' thesis topics or chosen clinical specialty. Correlations demonstrated significant relationships between graduates' perceptions of research self-efficacy and their interest in clinical research careers.

The present investigation aimed to assess the health-related QoL (HRQoL) of elderly people living in two settings: (i) rural community and (ii) homes for the elderly in a district of South India. The data are drawn from elderly (>60 years of age) sampled from both settings. The short form 36-item health survey (SF-36) was administered to all respondents. The average scores for several domains, including total physical health, total mental health and overall health (total SF-36 score) were around 50, which can be interpreted as a moderate level of health-related QoL. Residents living in a home for the elderly scored better in all domains except for role-physical and role-emotional. Though univariate analysis revealed some associations between characteristics of elderly SF-36 scores, the multiple regression analysis indicated that working status yields a significant but negative coefficient for total SF-36 score among community dwelling elderly. The elderly report that their lives are better when they are staying in homes for the elderly. Hence, despite the socio-economic conditions, provision of a better and conducive environment by setting up more charity-based homes for the elderly may be one of the options for relative betterment of the QoL of the elderly, particularly those who are socially and economically deprived. Finally, the study warrants the need of normative values of SF-36 for various population groups in India.

Urease from Helicobacter pylori is inactivated by sulforaphane and other isothiocyanates.

PubMed

Fahey, Jed W; Stephenson, Katherine K; Wade, Kristina L; Talalay, Paul

2013-05-24

Infections by Helicobacter pylori are very common, causing gastroduodenal inflammation including peptic ulcers, and increasing the risk of gastric neoplasia. The isothiocyanate (ITC) sulforaphane [SF; 1-isothiocyanato-4-(methylsulfinyl)butane] derived from edible crucifers such as broccoli is potently bactericidal against Helicobacter, including antibiotic-resistant strains, suggesting a possible dietary therapy. Gastric H. pylori infections express high urease activity which generates ammonia, neutralizes gastric acidity, and promotes inflammation. The finding that SF inhibits (inactivates) urease (jack bean and Helicobacter) raised the issue of whether these properties might be functionally related. The rates of inactivation of urease activity depend on enzyme and SF concentrations and show first order kinetics. Treatment with SF results in time-dependent increases in the ultraviolet absorption of partially purified Helicobacter urease in the 260-320 nm region. This provides direct spectroscopic evidence for the formation of dithiocarbamates between the ITC group of SF and cysteine thiols of urease. The potencies of inactivation of Helicobacter urease by isothiocyanates structurally related to SF were surprisingly variable. Natural isothiocyanates closely related to SF, previously shown to be bactericidal (berteroin, hirsutin, phenethyl isothiocyanate, alyssin, and erucin), did not inactivate urease activity. Furthermore, SF is bactericidal against both urease positive and negative H. pylori strains. In contrast, some isothiocyanates such as benzoyl-ITC, are very potent urease inactivators, but are not bactericidal. The bactericidal effects of SF and other ITC against Helicobacter are therefore not obligatorily linked to urease inactivation, but may reduce the inflammatory component of Helicobacter infections.

The transcription factor SF-1 (steroidogenic factor-1) is a master regulator of steroidogenesis. Previously, we have found that SF-1 induces the differentiation of mesenchymal stem cells into steroidogenic cells. To elucidate the molecular mechanisms of SF-1-mediated functions, we attempted to identify protein components of the SF-1 nuclear protein complex in differentiated cells. SF-1 immunoaffinity chromatography followed by MS/MS analysis was performed, and 24 proteins were identified. Among these proteins, we focused on C/EBPβ (CCAAT/enhancer-binding protein β), which is an essential transcription factor for ovulation and luteinization, as the transcriptional mechanisms of C/EBPβ working together with SF-1 are poorly understood. C/EBPβ knockdown attenuated cAMP-induced progesterone production in granulosa tumour-derived KGN cells by altering STAR (steroidogenic acute regulatory protein), CYP11A1 (cytochrome P450, family 11, subfamily A, polypeptide 1) and HSD3B2 (hydroxy-δ-5-steroid dehydrogenase, 3β- and steroid δ-isomerase 2) expression. EMSA and ChIP assays revealed novel C/EBPβ-binding sites in the upstream regions of the HSD3B2 and CYP11A1 genes. These interactions were enhanced by cAMP stimulation. Luciferase assays showed that C/EBPβ-responsive regions were found in each promoter and C/EBPβ is involved in the cAMP-induced transcriptional activity of these genes together with SF-1. These results indicate that C/EBPβ is an important mediator of progesterone production by working together with SF-1, especially under tropic hormone-stimulated conditions.

Objective To explore the role of patients’ beliefs in their likelihood of recovery from severe physical trauma. Methods We developed and validated an instrument designed to capture the impact of patients’ beliefs on functional recovery from injury; the Somatic Pre-occupation and Coping (SPOC) questionnaire. At 6-weeks post-surgical fixation, we administered the SPOC questionnaire to 359 consecutive patients with operatively managed tibial shaft fractures. We constructed multivariable regression models to explore the association between SPOC scores and functional outcome at 1-year, as measured by return to work and short form-36 (SF-36) physical component summary (PCS) and mental component summary (MCS) scores. Results In our adjusted multivariable regression models that included pre-injury SF-36 scores, SPOC scores at 6-weeks post-surgery accounted for 18% of the variation in SF-36 PCS scores and 18% of SF-36 MCS scores at 1-year. In both models, 6-week SPOC scores were a far more powerful predictor of functional recovery than age, gender, fracture type, smoking status, or the presence of multi-trauma. Our adjusted analysis found that for each 14 point increment in SPOC score at 6-weeks (14 chosen on the basis of half a standard deviation of the mean SPOC score) the odds of returning to work at 1-year decreased by 40% (odds ratio = 0.60; 95% CI = 0.50 to 0.73). Conclusion The SPOC questionnaire is a valid measurement of illness beliefs in tibial fracture patients and is highly predictive of their long-term functional recovery. Future research should explore if these results extend to other trauma populations and if modification of unhelpful illness beliefs is feasible and would result in improved functional outcomes.

Aquaporins are membrane channels that facilitate the flow of water across biological membranes. Two conserved regions are central for selective function: the dual asparagine-proline-alanine (NPA) aquaporin signature motif and the aromatic and arginine selectivity filter (SF). Here, we present the crystal structure of a yeast aquaporin at 0.88 angstrom resolution. We visualize the H-bond donor interactions of the NPA motif's asparagine residues to passing water molecules; observe a polarized water-water H-bond configuration within the channel; assign the tautomeric states of the SF histidine and arginine residues; and observe four SF water positions too closely spaced to be simultaneously occupied. Strongly correlated movements break the connectivity of SF waters to other water molecules within the channel and prevent proton transport via a Grotthuss mechanism.

The aims were to investigate how the body image is affected in fibromyalgia syndrome (FMS) in comparison to healthy people, as well as to explore the relationship of the body image with the level of pain, functional status, severity of depression, and quality of life (QoL). Demographic variables, symptoms of fibromyalgia, and number of fibromyalgia tender points for 51 patients with FMS and 41 control subjects were recorded. All patients were asked to mark the level of pain on visual analogue scale (VAS). Six-minute walking test was recorded for functional assessment. The impact of the disease was evaluated by fibromyalgia impact questionnaire (FIQ). All patients were asked to complete body image scale (BIS), Beck depression inventory (BDI), and short form-36 (SF-36). There were no differences between groups with regard to demographic variables (p>0.05). Mean VAS was 7.5±1.4 for the patients with FMS and 0.3±0.4 for control subjects (p<0.05). Mean FIQ was 70.8±13.2 and 8.2±9.6 for the FMS and control groups, respectively (p<0.05). Mean BIS and BDI were 106.5±24.0 and 20.2±11.2 for FMS group and 66.3±23.4 and 3.4±4.0 for control group, respectively (p<0.05). SF-36 subscores were found to be significantly lower in patients with FMS than control subjects (p<0.05), except for the social function subscore. BIS score had significant relationships both with VAS (r=0.843) and FIQ (r=0.290) in patients with FMS (p<0.05). There were significant relationships between BIS scores and SF-36 pain (r= -0.288), energy/vitality (r= -0.519), mental health (r= -0.442), and general health (r= -0,492) subscores (p<0.05). Body image was associated with VAS in the multivariate linear regression analysis. The results of the present study indicate that body image is disturbed in patients with FMS compared to control subjects. For the evaluation of the level of pain, impact of the disease, and QoL in patients with FMS, it would be useful to consider the relationship of the body image disturbance with these parameters.

Membrane proteins sense extracellular cues and transduce intracellular signaling to coordinate directionality and speed during cellular migration. They are often localized to specific regions, as with lipid rafts or tetraspanin-enriched microdomains; however, the dynamic interactions of tetraspanins with diverse receptors within tetraspanin-enriched microdomains on cellular surfaces remain largely unexplored. Here, we investigated effects of tetraspan(in) TM4SF5 (transmembrane 4 L6 family member 5)-enriched microdomains (T 5 ERMs) on the directionality of cell migration. Physical association of TM4SF5 with epidermal growth factor receptor (EGFR) and integrin α5 was visualized by live fluorescence cross-correlation spectroscopy and higher-resolution microscopy at the leading edge of migratory cells, presumably forming TM4SF5-enriched microdomains. Whereas TM4SF5 and EGFR colocalized at the migrating leading region more than at the rear, TM4SF5 and integrin α5 colocalized evenly throughout cells. Cholesterol depletion and disruption in TM4SF5 post-translational modifications, including N -glycosylation and palmitoylation, altered TM4SF5 interactions and cellular localization, which led to less cellular migration speed and directionality in 2- or 3-dimensional conditions. TM4SF5 controlled directional cell migration and invasion, and importantly, these TM4SF5 functions were dependent on cholesterol, TM4SF5 post-translational modifications, and EGFR and integrin α5 activity. Altogether, we showed that TM4SF5 dynamically interacted with EGFR and integrin α5 in migratory cells to control directionality and invasion.-Kim, H.-J., Kwon, S., Nam, S. H., Jung, J.

To assess and compare the validity of six physical function measures in people awaiting hip or knee joint replacement. Eighty-two people awaiting hip or knee replacement were assessed using six physical function measures including the WOMAC Function scale, SF-36 Physical Function scale, SF-36 Physical Component Summary scale, Patient Specific Functional Scale, 30-second chair stand test, and 50-foot timed walk. Validity was assessed using a head-to-head comparison design. Convergent validity was demonstrated with significant correlations between most measures (Spearman's rho 0.22 to 0.71). The Patient Specific Functional Scale had the lowest correlations with other measures of physical function. Discriminant validity was demonstrated with low correlations between mental health and physical function scores (Spearman's rho -0.12 to 0.33). Only the WOMAC Function scale, 30-second chair stand test, and 50-foot timed walk demonstrated known groups validity when scores for participants who walked with a gait aid were compared with those who did not. Standardized response means and Guyatt's responsiveness indexes indicated that the SF-36 was the least responsive measure. For those awaiting joint replacement surgery of the hip or knee, the current investigation found that the WOMAC Function scale, 30-second chair stand test, and 50-foot timed walk demonstrated the most evidence of validity. The Patient Specific Functional Scale might complement other measures by capturing a different aspect of physical function.

Phosphorylation and Intramolecular Stabilization of the Ligand Binding Domain in the Nuclear Receptor Steroidogenic Factor 1

Steroidogenic factor 1 (SF-1) is an orphan nuclear receptor with no known ligand. We showed previously that phosphorylation at serine 203 located N′-terminal to the ligand binding domain (LBD) enhanced cofactor recruitment, analogous to the ligand-mediated recruitment in ligand-dependent receptors. In this study, results of biochemical analyses and an LBD helix assembly assay suggest that the SF-1 LBD adopts an active conformation, with helices 1 and 12 packed against the predicted alpha-helical bundle, in the apparent absence of ligand. Fine mapping of the previously defined proximal activation function in SF-1 showed that the activation function mapped fully to helix 1 of the LBD. Limited proteolyses demonstrate that phosphorylation of S203 in the hinge region mimics the stabilizing effects of ligand on the LBD. Moreover, similar effects were observed in an SF-1/thyroid hormone LBD chimera receptor, illustrating that the S203 phosphorylation effects are transferable to a heterologous ligand-dependent receptor. Our collective data suggest that the hinge together with helix 1 is an individualized specific motif, which is tightly associated with its cognate LBD. For SF-1, we find that this intramolecular association and hence receptor activity are further enhanced by mitogen-activated protein kinase phosphorylation, thus mimicking many of the ligand-induced changes observed for ligand-dependent receptors.

Objective People with chronic pain and depression have worse health outcomes than those with chronic pain alone. Little is known about the effectiveness of depression treatment for this population. We examined the effect of depression treatment on medical and social outcomes for individuals with chronic pain and depression Methods Propensity score weighted analyses using both waves (1997-1998 and 2000-2001) of the National Survey of Alcohol, Drug, and Mental Health Problems were used to examine the effect of (1) any depression treatment and (2) minimally adequate depression treatment on persistence of depression symptoms, depression severity, pain severity, overall health, mental health status, physical health status, social functioning, employment status, and number of work days missed. Analyses were limited to those who met CIDI-SF criteria for major depressive disorder, reported having at least one chronic pain condition, and completed both interviews (n=553). Results Receiving any depression treatment was associated with higher scores on the mental component summary of the MOS SF-12, indicating better mental health (difference = 2.65 points, p=0.002) and less interference of pain on work (OR=0.57, p=0.02). Among those receiving treatment, minimal adequacy of treatment was not significantly associated with better outcomes. Conclusions Depression treatment improves mental health and reduces the effects of pain on work among those with chronic pain and depression. Understanding the effect of depression treatment on outcomes for this population is important for employers, healthcare providers treating this population, and policymakers working in this Decade of Pain Control and Research to improve care for chronic pain sufferers.

Quality of life (QOL) is one of the health indexes for which many efforts have been made to define and measure during the last four decades of the 20(th) century in many countries. This paper is aimed at studying the QOL in relation to socioeconomic status of the general population of Isfahan in 1390. We applied a descriptive-analytical and sectional method. In this research, 385 women and men over 15 years of age from 14 regions of Isfahan's municipality were studied using multi-stage quota sampling. We examined QOL using the SF-36 standard questionnaire, along with two domains of mental and physical health and eight subscales within the validity domain of 65-90%. Social (81%) and economical (70%) status was also measured by the questionnaire instrument in both objective and subjective domains after confirming the validity and reliability of the instruments. The given data were analyzed by SPSS 17 software and using descriptive and statistical tests. The indicators of QOL showed that a score deviation of the SF-36 questionnaire in physical health (SD = 2.31) and mental health (SD = 3.22) domains was obtained from the population. Of the eight subscales, bodily pains and limitations on functioning as physical and mental had an inverse relationship with socioeconomic status. However, physical health, mental health, social activities, public health, and vitality had a significant positive relationship, including different strengths and weaknesses, with socioeconomic status. Also, sexuality and housing status had no relationship with QOL. There is a direct and significant relationship between quality of life and socioeconomic status variables in Isfahan.

The aim of this study was to (1) translate the Gastrointestinal Tract Instrument (GIT) 2.0 from English to Chinese and (2) validate both versions in a multi-ethnic systemic sclerosis cohort in Singapore (SCORE). The English GIT2.0 was translated to Chinese using a standard forward-backward translation approach. Psychometric evaluation of the GIT2.0 included internal consistency reliability (using Cronbach's alpha), test-retest reliability (using intra-class correlation coefficient (ICC)), scale level factor analysis, and construct validity (using Spearman correlation) against the modified Scleroderma Health Assessment Questionnaire (S-HAQ) and the SF-36 v2. Most of the patients were females (88.6%) and Chinese (78.2%), with mean (SD) age of 51.0 (13.0) years and median disease duration of 4.5 years. We administered English (n = 146) and Chinese (n = 74) GIT2.0. The mean (SD) total GIT score was 0.29 (0.37). There was good internal consistency (Cronbach's alpha >0.70 for all subscales) and good test-retest reliability for the scale and all subscales (ICC 0.71-0.92) except for "diarrhoea" (ICC = 0.54). Our hypothesised a priori construct validity was supported by moderate correlations between the total GIT score and S-HAQ GI subscale (r = 0.446), and the social functioning subscale and SF36v2 role-social domain (r = 0.337), and weak-to-moderate correlation between the emotional subscale and SF-36v2 role-emotional (r = 0.295) and mental health (r = 0.298) domains and mental component summary (r = 0.356). Exploratory factor analysis of the seven subscales yielded a two-factor solution explaining 69.63% of the total variance. This study provides evidence for the reliability and validity of the English and Chinese GIT2.0 to be used in Singapore for research and routine practice.

A two-stage case-control study was conducted to examine the association between six candidate U2-depedent spliceosome genes (SRSF1, SRSF2, SF3A1, SF3B1, SF1 and PRPF40B) and pancreatic cancer (PC). Subjects with one or two T alleles at rs2074733 in SF3A1 had a lower risk of PC compared to those with two C alleles in combined two populations (OR: 0.59, 95% confidence interval: 0.48-0.73, False discovery rate (FDR)-P = 1.5E-05). Moreover, the presence of the higher-risk genotype at rs2074733 plus smoking or drinking had synergic effects on PC risk. These findings illustrate that RNA splicing-related genes appear to be associated with the occurrence of PC, and show synergic interactions with smoking and drinking in the additive model. In the future, our novel findings should be further confirmed by functional studies and independent large-scale population studies.

The survival functions (SF) during acute exposures to cadmium, zinc or low pH were examined for amphipods exhibiting variation at three loci. Significant differences were observed in eight of nine locus/toxicant combinations. Two general types of survival curve patterns were identified when genotype-related SF differences were observed. In the first pattern, the survival differences between genotypes were immediately apparent with two SF curves separated at the beginning of exposure with little or no overlap. For the second pattern, both genotypes had similar SF for a period of time, during which the two survival curves crossed or overlapped. After this period, the survival probability of one genotype dropped sharply relative to the other. While SF was related to genotype, it was not related to heterozygosity. Genetic distance analysis showed that exposure to cadmium, zinc or low pH each resulted in directional selection, suggesting the potential use of genetic distance as a bioindicator.

Function and horizontal transfer of the small terminase subunit of the tailed bacteriophage Sf6 DNA packaging nanomotor

Bacteriophage Sf6 DNA packaging series initiate at many locations across a 2 kbp region. Our in vivo studies that show that Sf6 small terminase subunit (TerS) protein recognizes a specific packaging (pac) site near the center of this region, that this site lies within the portion of the Sf6 gene that encodes the DNA-binding domain of TerS protein, that this domain of the TerS protein is responsible for the imprecision in Sf6 packaging initiation, and that the DNA-binding domain of TerS must be covalently attached to the domain that interacts with the rest of the packaging motor. The TerS DNA-binding domain is self-contained in that it apparently does not interact closely with the rest of the motor and it binds to a recognition site that lies within the DNA that encodes the domain. This arrangement has allowed the horizontal exchange of terS genes among phages to be very successful. PMID:23562538

To compare the effects of exergames (EGs) using the Xbox Kinect™ device and home exercise (HE) on balance, functional mobility, and quality of life of individuals aged 65 years or older. One hundred participants who met the inclusion criteria were randomized to the EG or HE group. The EG group took part in a 6-week programme using the Xbox360Kinect™ device, and the HE group took part in a 6-week balance exercise programme at home 5 days a week. The Berg Balance Scale (BBS) was used to assess balance, the Timed Up and Go (TUG) test was used to evaluate functional walking, and the Short Form 36 (SF-36) was used to assess quality of life. Forty-eight participants in the EG group and 42 participants in the HE group completed the study. The groups were similar in terms of age, sex, and pretreatment values of BBS, TUG, and SF-36. Although the BBS scores of both groups improved significantly (all p<0.05), the post-treatment scores of the EG group were better than those of the HE group. The TUG scores improved only in the EG group (p<0.05). The increase in the BBS scores and decrease in the TUG test scores were significant only in the EG group (all p<0.05). A significant improvement was also observed in the quality of life parameters of physical functioning, social role functioning, physical role restriction, general health perceptions, and physical component scores in the post-exercise evaluations of the EG group. The participants commented that they found the EG programme very entertaining. The EG can be considered a safe, entertaining and sustainable alternative to HE programmes, and it may have positive effects on balance, functional walking and quality of life in geriatric subjects.

To analyse the effect of a 24-week physical training programme in water and on land on women with fibromyalgia. A controlled study was conducted from December 2009 to May 2010. Seventy-two women with fibromyalgia (age: 51.79±7.87 years) were assigned to an exercise group (3 sessions/week, 2 sessions in water, 1 session on land) (n=42) and to a control group (n=30). The variables analysed were: number of tender points, visual analogue scale (VAS) of pain, algometer score, functional capacity (leg strength, hand-grip dynamometry, flexibility, agility, balance, aerobic endurance, heart response), body composition (body mass index, fat mass index, skeletal muscle mass index and percentage of body fat) and psychological variables (Fibromyalgia Impact Questionnaire [FIQ] and Short Form Health Survey 36 [SF-36]). The exercise group improved in the algometer score (p<0.001), positive tender points (p=0.005), VAS (p<0.001) and FIQ (p<0.001). Improvements were also detected in functional capacity (leg strength, p=0.001; hand-grip dynamometry, p=0.001; flexibility, p<0.001; balance, p=0.006; 6-minute walk test, p<0.001; mean heart rate, p=0.031; maximum heart rate, p<0.001 and VO2 max, p<0.001). There was a decrease in the percentage of body fat (p=0.040). There was also an improvement in the subscales of the SF-36; vitality (p=0.004), mental health (p=0.001) social role functioning (p=0.020) and general health functioning (p=0.002). The findings of this study show that a 24-week physical training programme (3 sessions/week, of which 2 sessions are in water and 1 session is on land) reduces pain and disease impact and improves functional capacity in women with fibromyalgia.

Given the multifaceted nature of this inherited neurodegenerative condition, typically affecting adults in mid-life, it is perhaps not surprising that studies indicate poorer Health Related Quality of Life (HrQoL) in those with the gene-expansion and, by association, in their families. This study aimed to extend the current literature by exploring specific life domains, including at an earlier disease stage than usually reported in the HRQoL literature, and in a subgroup of gene-negative partners. 355 participants from the TRACK-HD cohort (120 Controls, 118 Pre-HD and 117 early-HD) completed standardised self-report measures of HrQoL (SF36 and QoLI), underwent clinical assessments of capacity and motor function (UHDRS), semi structured interviews assessing neuropsychiatric symptoms (PBA-s), completed paper and computerized cognitive tasks and assessment of behaviours associated with damage to frontal brain circuits (FrSBe). Each gene-expanded group scored statistically significantly lower than gene-negative sibling controls on the SF36 General Health subscale; neuropsychiatric symptoms and executive dysfunction were associated with reduced HrQoL. Those with Stage II disease reported statistically significantly lower HrQoL than gene-negative controls across physical, emotional and social life domains. Those partnered with manifest participants reported lower HrQoL in the social domain compared to those partnered with at-risk participants furthest from disease onset; and perseverative symptoms in manifest partners were found to be related to lower HrQoL in their gene-negative partners. HrQoL in gene-negative partners of pre-manifest individuals was associated with pre-manifest individuals' neuropsychiatric and cognitive function. Understanding the nature and timing of disruption to the HrQoL in people who are pre-manifest and diagnosed with HD, and their gene-negative partners, can inform the development of appropriate strategies and interventions.

The increasing prevalence of treated end-stage renal disease and low transplant rates in Africa leads to longer durations on dialysis. Dialysis should not only be aimed at prolonging lives but also improve quality of life (QOL). Using mixed methods, we investigated the QOL of patients on chronic haemodialysis (HD) and peritoneal dialysis (PD). We conducted a cross-sectional study at Tygerberg Hospital in Cape Town, South Africa. All the PD patients were being treated with continuous ambulatory peritoneal dialysis. The KDQOL-SF 1.3 questionnaire was used for the quantitative phase of the study. Thereafter, focus-group interviews were conducted by an experienced facilitator in groups of HD and PD patients. Electronic recordings were transcribed verbatim and analysed manually to identify emerging themes. A total of 106 patients completed questionnaires and 36 of them participated in the focus group interviews. There was no difference between PD and HD patients in the overall KDQOL-SF scores. PD patients scored lower with regard to symptoms (P = 0.005), energy/fatigue (P = 0.025) and sleep (P = 0.023) but scored higher for work status (P = 0.005) and dialysis staff encouragement (P = 0.019) than those on HD. Symptoms and complications were verbalised more in the PD patients, with fear of peritonitis keeping some housebound. PD patients were more limited by their treatment modality which impacted on body image, sexual function and social interaction but there were less dietary and occupational limitations. Patients on each modality acknowledged the support received from family and dialysis staff but highlighted the lack of support from government. PD patients had little opportunity for interaction with one another and therefore enjoyed less support from fellow patients. PD patients experienced a heavier symptom burden and greater limitations related to their dialysis modality, especially with regards to social functioning. The mixed-methods approach helped to identify several issues affecting quality of life which are amenable to intervention.

Background Treatment objectives for dyspepsia include improvements in both symptoms and health-related quality of life (HRQoL). There is a lack of disease-specific instruments measuring HRQoL in South East Asian dyspeptics. Objectives To validate English and locally translated version of the Short-Form Nepean Dyspepsia Index (SF-NDI) in Malaysian patients who consult for dyspepsia. Methods The English version of the SF-NDI was culturally adapted locally and a Malay translation was developed using standard procedures. English and Malay versions of the SF-NDI were assessed against the SF-36 and the Leeds Dyspepsia Questionnaire (LDQ), examining internal consistency, test-retest reliability and construct validity. Results Pilot testing of the translated Malay and original English versions of the SF-NDI in twenty subjects did not identify any cross-cultural adaptation problems. 143 patients (86 English-speaking and 57 Malay speaking) with dyspepsia were interviewed and the overall response rate was 100% with nil missing data. The median total SF-NDI score for both languages were 72.5 and 60.0 respectively. Test-retest reliability was good with intraclass correlation coefficients of 0.90 (English) and 0.83 (Malay), while internal consistency of SF-NDI subscales revealed α values ranging from 0.83 – 0.88 (English) and 0.83 – 0.90 (Malay). In both languages, SF-NDI sub-scales and total score demonstrated lower values in patients with more severe symptoms and in patients with functional vs organic dyspepsia (known groups validity), although these were less marked in the Malay language version. There was moderate to good correlation (r = 0.3 – 0.6) between all SF-NDI sub-scales and various domains of the SF-36 (convergent validity). Conclusion This study demonstrates that both English and Malay versions of the SF-NDI are reliable and probably valid instruments for measuring HRQoL in Malaysian patients with dyspepsia.

Social support has been considered one of the most important factors of health-related quality of life (HRQoL) evaluations among different populations; however, few studies have explored the relationships of both received and perceived social support to HRQoL among patients undergoing methadone maintenance treatment (MMT). Thus, the purpose of this cross-sectional study was to clarify these relationships. Participants were patients admitted at the two largest privately and publicly funded MMT clinics in Xi'an. The main explanatory variable was social support, both received (i.e., social network support and professional support services) and perceived (Multidimensional Scale of Perceived Social Support). The outcome was HRQoL, which was evaluated using the Short-Form 36 Health Survey version 2 (SF-36v2) and the Quality of Life Scale for Drug Addicts (QOL-DAv2.0). We carried out independent samples t-tests and multiple linear regression analysis to examine the relationships between received and perceived social support and HRQoL. The study findings revealed that patients with good social support had significantly higher scores on the SF-36v2 and QOL-DAv2.0 (p < 0.05). After controlling for individual characteristics, the significant factors predicting HRQoL were good family relationships, usually communicating with others, a convenient service time, appropriate treatment charges, and good perceived social support (p < 0.05). Our results suggest that received and perceived social support influences HRQoL among individuals receiving MMT. Thus, these variables should be considered during health management efforts and interventions directed at this patient population.

The present study was aimed to validate two normalised short-form (SF) Mini-Nutritional Assessments (MNA) that contained either BMI (Taiwan version 1, T1) or calf circumference (CC; Taiwan version 2, T2) for rating the nutritional status of elderly Taiwanese. Both versions adopted Taiwanese anthropometric cut-offs, but T2 further had the BMI item replaced by CC. We compared the ability of the two SF in rating the nutritional status of 2674 elderly Taiwanese in the 1999 ‘Taiwan Longitudinal Survey on Aging’ with their respective full versions. We evaluated the agreement between the SF and full scales with weighted κ and performed Cox regression analysis for the follow-up 4-year mortality according to nutritional status rated at baseline. The results showed that the agreements between the respective SF and the full MNA were good (weighted κ: 0·679 for T1 and 0·667 for T2). Both SF performed well in predicting follow-up 4-year mortality relative to the full MNA. In conclusion, MNA-T1-SF and -T2-SF have good consistency with the full MNA and have quite comparable abilities in rating the nutritional status of elderly Taiwanese. Both SF versions appear appropriate for functioning as stand-alone units for rating the nutritional status of the elderly in community-living settings or the general population.

The effects of using different approaches to scoring the SF-12 summary scales of physical and mental health were examined with a view to informing the design and interpretation of community-based survey research. Data from a population-based study of 7485 participants in three cohorts aged 20-24, 40-44 and 60-64 years were used to examine relationships among measures of physical and mental health calculated from the same items using the SF-12 and RAND-12 approaches to scoring, and other measures of chronic physical conditions and psychological distress. A measure of physical health constructed using the RAND-12 scoring showed a monotonic negative association with psychological distress as measured by the Goldberg depression and anxiety scales. However, a non-monotonic association was evident in the relationship between SF-12 physical health scores and distress, with very high SF-12 physical health scores corresponding with high levels of distress. These relationships highlight difficulties in interpretation that can arise when using the SF-12 summary scales in some analytical contexts. It is recommended that community surveys that measure physical and mental functioning using the SF-12 items generate summary scores using the RAND-12 protocol in addition to the SF-12 approach. In general, researchers should be wary of using factor scores based on orthogonal rotation, which assumes that measures are uncorrelated, to represent constructs that have an actual association.

We examined the psychometric qualities of the Short Form of the Coopersmith Self-Esteem Inventory (SF-CSEI) in a large sample of French adolescents and young adults. A 25-item French version was administered to 1,362 participants (561 aged below 16 years and 801 aged 16-25 years). Participants also completed other scales to measure construct validity (e.g., Rosenberg Self-Esteem Scale, Hospital Anxiety and Depression Scale, and General Health Questionnaire). Factorial analysis yielded evidence for a structure with three first-order factors for the SF-CSEI: personal, social, and family-derived self-esteem. The internal consistency of the questionnaire's different dimensions was satisfactory (Cronbach's α = .68-.77). Pearson's correlation coefficients showed that the SF-CSEI had moderate to high correlations with convergent measures (r = .19-.73) and constructs related to self-esteem (r = -.23-.65). Psychiatric patients (n = 67) scored significantly lower than a control group. Test-retest reliability was good for some of the factors, especially at 5 weeks and 1 year (r = .29-.79). The French version of the SF-CSEI appears to be a useful instrument, with a cross-culturally stable factorial structure. © The Author(s) 2015.

While symptoms of deficient emotional self-regulation (DESR) such as low frustration tolerance, temper outbursts, emotional impulsivity, and mood lability are commonly associated with attention deficit hyperactivity disorder (ADHD), little is known about their nature. The main aim of this post hoc study was to examine the correlates of DESR in a large sample of adults with and without ADHD. Subjects were 206 adults with ADHD and 123 adults without ADHD from a family study of ADHD. Emotional impulsivity was operationalized using items from the Barkley Current Behavior Scale. Subjects were comprehensively assessed for psychiatric comorbidity using structured diagnostic interview methodology. We used the Quality of Life, Enjoyment, and Satisfaction Questionnaire-Short Form (QLES-Q-SF) and Social Adjustment Scale-Self-report (SAS-SR) to assess quality of life and psychosocial functioning. DESR was more common among ADHD compared with non-ADHD adults, and 55 % of adults with ADHD reported extreme DESR of greater severity than 95 % of control subjects. The association of ADHD and DESR was not entirely accounted for by either current or lifetime comorbid disorders. DESR was also associated with significant functional impairment as evaluated by the QLES-Q-SF and SAS-SR, and with reduced marital status, as well as higher risk for traffic accidents and arrests. DESR adversely impacts quality of life in adults with ADHD. More work is needed to further evaluate DESR in clinical and investigational studies of subjects with ADHD. PMID:23413201

Various researchers have shown that the health level, performance status, and quality of life (QOL) are often less than expected especially in hemodialysis (HD) patients. This study aimed to determine the effect of the two methods of educational programs on health- related QOL (HRQOL) in Iranian HD patients. In this quasi-experimental, pretest-posttest interventional study, we employed each subject as his/her own control. The study was conducted at the dialysis units in three major general hospitals affiliated with Ahvaz Jundishapur University of Medical Sciences. A total of 90 HD patients were randomly allocated to two 45-patient groups of oral and video education programs, respectively. The educational programs included dietary and fluid regimens, the care of fistula and skin, and stress management. HRQOL was assessed in both groups using a Farsi version of the Short Form Health Survey (SF-36) before and after the educational programs. Repeated measures analysis of variance and ANOVA were used for data analysis through SPSS. SF-36 domains of physical functioning (P < 0.021), role physical (P < 0.031), social functioning (P < 0.001) and mental health (P < 0.001) were significantly increased in both oral and vide education groups after the interventions. There was no difference in the effectiveness of the two educational programs. Appropriate interventions may potentially lead to improvement in the HRQOL of these patients. Therefore, video education as an effective, inexpensive, simple, and attractive method is recommended for HD patients.

Spine and spinal cord injury in motor vehicle crashes: a function of change in velocity and energy dissipation on impact with respect to the direction of crash.

To examine the effect of change in velocity (DeltaV) and energy dissipation (IE) on impact, above and below the test levels for Federal MVC Safety Standards, on the incidence of spine fractures (SF), spinal cord injury (SCI)), SF mortality and the associated injury patterns in Frontal (F) and Lateral (L) MVCs. Comparison of 214 patients with SF or SCI with 938 patients who did not have SF or SCI. 1152 MVC adult drivers or front-seat passengers (701 F & 451 L) evaluated at 10 Level I CIREN study Trauma Centers together with vehicle and crash scene engineering reconstruction. Patient seat belt (SB) and/or airbag (AB) use correlated with clinical, or autopsy findings. The relationship between DeltaV and IE rose exponentially as DeltaV increased. Of the 1152 patients, all with AIS> or =3 injuries, there were 214 patients with spine fractures of AIS > or =2. In FMVCs there were more SF patients with Cervical SF than in LMVCs (68F versus 64 L) and more Thoracic (35F versus 21L) and Lumbar (39F versus 16L) SF. However, the incidence of spinal cord injury was greatest in the Cervical SF (33%), compared with the Thoracic SF (18%), or Lumbar SF (2%). Most important, in FMVCs 49% of SF, 47% of SCI and 71% of the SF deaths (p < 0.05) occurred at > mean of 47.4 kph. In contrast, in LMVCs 51% of SF, 52% of SCI and 67% of the SF deaths occurred at DeltaV > mean of 35.3 kph. However, 80% of all deaths in SCI occurred in Cervical SF cases, in these 74% also had a brain injury. In contrast, the deaths in Thoracic SF were due to combinations of brain (45%), thorax (95%) or associated pelvic fracture injuries (50%). Airbag (AB), or Seat belt (SB) restraints appeared to protect FMVC SF patients from SCI at lower DeltaV, but 84% of Cervical SCI patients at DeltaV > 47 kph had AB protection and in a few cases the AB appeared responsible for the SCI. In contrast, 82% of Lumbar SF patients had SB, but in FMVCs where jackknifing due to backloading occurred, improper SB positioning may have contributed to the SF. The implication for SCI in both front seat drivers and passengers in either FMVC or LMVC crashes above their respective DeltaV means is that improved spine fracture protection is necessary at higher DeltaV levels. More effective safety systems to prevent Cervical SCIs should be developed using two-level frontal and side AB & SB+pretensioner devices, which protect against SF at DeltaV both at and 1SD above the FMVC (47 & 72 kph = 30 & 45 mph) and LMVC (35 & 54 kph =22 & 34 mph) means.

'Stress' and 'health-related quality of life' (HRQoL) are two important theoretical constructs for modern therapy evaluation with clinical relevance. Eurythmy therapy (EYT) is a mind-body-therapy derived from anthroposophic medicine with promising effects on heart rate variability (HRV), HRQoL and disease scores. The purpose of this study was to investigate the impact of EYT on stress coping strategies (SCS) and HRQoL in a controlled study with moderately stressed participants. 68 healthy, moderately stressed adults (mean age: 42.2; SD: 8.2) performed 10h of EYT in a group setting over a period of six weeks. A non-randomised control group of 22 healthy adults (mean age: 43.6; SD: 13.7) received no intervention and did only complete the questionnaires at the same data points. Outcomes were measured before and after the intervention (AVEM & SF-36). A significant impact on SCS was found in seven AVEM scales (MANOVA, F (1/74)=4.59; p=.04). With regard to changes in risk pattern affiliation (AVEM), 24% of the participants receiving EYT (n=55) changed over time from a risky stress coping pattern to a healthier pattern. Concerning the HRQoL four normally distributed scales of the SF-36 ('vitality', 'social functioning', 'mental health' and 'physical functioning') showed a significant group×time interaction favouring the EYT group (MANOVA, F (1/74)=17.26; p<.001). Statistically and clinically relevant mean differences over time of at least eight scale points were found for 'role physical', 'bodily pain', 'vitality' and 'mental health', and of at least 15 scale points for 'role emotional' and 'social functioning'. A six-week period of EYT training can result in a significant reduction of stress and consequently improve QoL. Because a significant proportion of participants had high levels of stress at baseline the results suggest a health-enhancing benefit of EYT that may have clinical potential for prevention of stress and associated disorders in healthy individuals and possibly in patients with chronic diseases, for example.

To investigate the effect and mechanism of sodium ferulate (SF) on reversing erectile dysfunction in diabetes mellitus (DM) rats. Forty-four male adult Sprague-Dawley rats were induced for diabetes by an intraperitoneal injection of streptozotocin. Then the successful models were randomly divided into DM + SF group and DM group (22 rats each respectively). The rats in DM +SF group were treated with sodium ferulate (100 mg x kg(-1) x d(-1)) through a daily gastric lavage. At Week 12, the erectile function of all rats was evaluated and serum samples were harvested. The SOD, CAT, NOS, MDA and NO levels in corpus cavernosum and serum were all measured. The pathologic change in penile cavernous body was observed microscopically. The diabetic rat models were successfully established. The erectile function was much better in normal control group and DM + SF group than that in DM group. And the penile erection rates in three groups were 100%, 66% and 22% respectively. The activity levels of SOD, CAT and NOS were markedly decreased in DM group as compared to those in normal control group and DM + SF group (P < 0.01). The NO content was approximately equal in normal control group and DM + SF group (112 +/- 28) nmol/ml vs (137 +/- 25) nmol/ml. But both were much higher than that in DM group (56 +/- 10) nmol/ml, both P < 0.01. The MDA content was markedly increased in DM group as compared to those in normal control group and DM + SF group (both P < 0.01). Microscopically, muscle fibers in penile cavernous body arranged disorderly, muscular mantle damaged and desmoplasia scattered among muscle fibers in DM group. Sodium ferulate may play interventional roles in reversing diabetic erectile dysfunction through metabolic regulation of free radicals, antagonism of oxidative insults and enhancement of NO production.

Few studies have prospectively assessed the impact of breast cancer (BC) on women's sexual lives. Therefore, this study examines the determinants of quality of sexual life (QOSL), sexual functioning (SF), and sexual enjoyment (SE) at 6 and 12 months after surgical treatment. All participants completed a measure of QOSL (The World Health Organization Quality of Life assessment instrument-100 (WHOQOL-100)-facet Sexual Activity) before diagnosis (Time-1), and 1 (Time-2), 3 (Time-3), 6 (Time-4) and 12 months (Time-5) after surgical treatment. At Time-1, women also completed questionnaires on personality (The State Trait Anxiety Inventory-trait, NEO-FFI), body image and self-esteem (WHOQOL-100), depressive symptoms (Center for Epidemiological Studies-Depression Scale), and fatigue (Fatigue Assessment Scale). Furthermore, SF and SE (The European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire Breast Cancer module) were measured from Time-2 onwards. At baseline, the analysis included 223 women with early stage BC. Clinical factors did not predict QOSL, SF or SE. In the final analyses, trait anxiety predicted QOSL and SF at Time-4 (p's<0.01). At Time-5, agreeableness predicted QOSL and SE (p's<0.05). Having a partner and age predicted SF, while SE was predicted by educational level (Time-4). In addition, fatigue predicted SE at Time-4 (p<0.05). In general, QOSL diminished across time, while SF improved. However, women with a mastectomy did not differ from women with breast conserving therapy. Mainly personality and psychological factors affect patients' sexuality after surgical treatment. Clinical factors did not predict QOSL, SF or SE. More knowledge in this field will help professionals to identify women who are at risk of experiencing sexual problems and consequently will contribute to provide adequate support.

Field-effect transistor (FET)-based biosensors have a wide range of applications, and a bio-FET odorant sensor, based on insect (Sf21) cells expressing insect odorant receptors (ORs) with sensitivity and selectivity, has emerged. To fully realize the practical application of bio-FET odorant sensors, knowledge of the cell-device interface for efficient signal transfer, and a reliable and low-cost measurement system using the commercial complementary metal-oxide semiconductor (CMOS) foundry process, will be indispensable. However, the interfaces between Sf21 cells and sensor devices are largely unknown, and electrode materials used in the commercial CMOS foundry process are generally limited to aluminium, which is reportedly toxic to cells. In this study, we investigated Sf21 cell-device interfaces by developing cross-sectional specimens. Calcium imaging of Sf21 cells expressing insect ORs was used to verify the functions of Sf21 cells as odorant sensor elements on the electrode materials. We found that the cell-device interface was approximately 10 nm wide on average, suggesting that the adhesion mechanism of Sf21 cells may differ from that of other cells. These results will help to construct accurate signal detection from expressed insect ORs using FETs.
