Moreover, P adsorbed by the chemical reaction in form of iron hydrogen phosphate can be solubilized by a phosphate-solubilizing microorganism of Pseudomonas aeruginosa, with the total solubilized P amount of 3.045 mg g-1 at the end of an incubation of 20 days. This study indicated that the iron-rich sludge-derived biochar could be used as a novel and beneficial functional material for P recovery from the liquid phase of anaerobic digestate. The recovered P with biochar can be re-utilized in garden soil as an efficient P-fertilizer, thus increasing the added values of both the liquid phase of anaerobic digestate and the iron-rich sludge. INTRODUCTION Social isolation in older adults is associated with high rates of adverse health outcomes. Older adults who have had a recent significant health event are likely to be at risk of social isolation following hospitalization. This study aims to identify risk factors amongst older adults at hospital discharge that are associated with social isolation at three months post-hospitalization. METHODS Older adults were surveyed at hospital discharge and three months post-hospitalization. Baseline data including demographics, self-reported quality of life, physical activity and capacity levels, lifestyle factors, symptoms of depression and anxiety were collected at discharge. Social isolation was measured using the Friendship Scale at the three-month follow-up. Regression analyses were used to examine the relationship between baseline characteristics and social isolation at three months post-hospitalization. RESULTS Older adults (n = 311) participated in the baseline survey, of whom 241 (78 %) completed the three-month survey. Higher depressive and anxiety symptoms at hospital discharge, comorbidity of cancer, history of cigarette smoking, prior access to community and respite service, and arrangement for shopping assistance post-discharge were factors independently associated with an increased risk of social isolation at three months post-hospitalization. DISCUSSION This study identified risk factors for social isolation that are unique to older post-hospitalized adults. These findings can help clinicians identify individuals at risk of social isolation and to target interventions that address these risk factors for the prevention of social isolation in older adults after hospitalization. OBJECTIVE The aims of this study were to examine the effects of dance intervention on frailty in pre-frail and frail older persons. DESIGN This is a quasi-experimental, two-group trial. SETTING Older adults living nursing home. PARTICIPANTS Participants aged ≥ 60 years with low physical activity (mean age was 81.8 years; 71 % were female) (N = 66). METHODS Participants allocated to the dance group attended 40 min dance sessions in a nursing home, three times a week for 12-weeks. Participants allocated to the control group maintained their normal daily activities. Assessments were conducted at baseline, 6 weeks, and 12 weeks by researchers blinded to the allocation. Frailty was measured based on Fried criteria. https://www.selleckchem.com/products/pd-1-pd-l1-inhibitor-1.html Estimates of frailty between groups over time were calculated using the generalized estimating equations (GEE) and mixed effects models. RESULTS The prevalence of frailty decreased over time in the dance group compared to the control group (P = 0.002). The mean frailty scores decreased 0.69 at 6 weeks and 1.06 at 12 weeks. Compared to the control group, the prevalence of slowness (p = 0.002), weakness (p = 0.005), and low physical activity (p less then 0.001) significantly decreased in the dance group. CONCLUSIONS Dance intervention may reduce the presence and severity of frailty in older adults. Slowness and low physical activity improve following 12 weeks of dance intervention. This research synthesis explored whether major personality dimensions relate to body dissatisfaction. A comprehensive literature search identified 26 studies (37 independent samples) that met inclusion criteria (364 effect sizes; n = 39,109). Data were analyzed using inverse-variance weighted random effects meta-analysis. Mean effect sizes from 30 individual meta-analyses provided evidence that neuroticism (r = .30), extraversion (r = -.17) and conscientiousness (r = -.16), and to a lesser extent openness (r = -.10) and agreeableness (r = -.08), relate to body dissatisfaction. Effect sizes were smaller in models that controlled for body mass index, with non-significant effects for openness and agreeableness. There was some evidence of publication bias and substantial heterogeneity in computed averages. Random effects meta-regression showed that the association between neuroticism and body dissatisfaction decreased as the sample age increased. Measurement was the most important moderator across personality dimensions, with measures of appearance evaluation and body appreciation often showing smaller associations than other measures of body dissatisfaction. Effect sizes were not moderated by sample sex or world-region. Overall, findings show that higher levels of neuroticism, and lower levels of extraversion and conscientiousness, are associated with a greater risk of body dissatisfaction in men and women irrespective of actual body weight. Social media (SM) can create a climate of social comparison and preoccupation with appearance, which can pose risks for emotional problems, such as depression and social anxiety. In this study, 763 adolescents and young adults reported time spent and intensity of social media use and preoccupation with both general and appearance-related (AR) social media activities and content. Associations were investigated with markers of depression and social anxiety symptoms and appearance sensitivities - appearance anxiety and appearance rejection sensitivity (appearance-RS). Social media use was positively associated with symptoms of depression, social anxiety, appearance anxiety, and appearance-RS. General and AR preoccupation had unique and positive associations with depression and social anxiety symptoms and with appearance sensitivities. AR preoccupation was also found to strengthen the relationship between time spent on social media and appearance-RS. Although there were gender differences on all measures, with young women scoring higher on all measures, there was no evidence that gender moderated the effects of AR social media preoccupation.
