Influencing factors of two-way social support for the old adults in China: A cross-sectional study.

This study aims to investigate the status and influencing factors of two-way social support among old adults. A cross-sectional study of 408 convenient samples of old adults was conducted using socio-demographic questionnaire, Brief 2-Way Social Support Scale, Modified Barthel index, General Well-being Schedule, Family APGAR Index, and Lubben Social Network Scale 6. The two-way social support score for old adults in China was (43.74±7.86), with the receiving and giving social support scoring (22.80±4.06) and (20.94±4.52), respectively. The multiple linear regression analysis revealed that family care, residence place, socioeconomic status, and social network were associated with both receiving and giving social support. Chronic diseases and religious beliefs were related to receiving social support, while gender, general well-being, and residence form were related to giving social support. Tailored interventions based on the distinct influencing factors are needed to enhance old adults' social support both as recipients and providers.

Adaptation and validation of the Abrams geriatric self-neglect assessment scale among older Chinese people admitted to the hospital.

OBJECTIVES: Elder self-neglect is a global public health problem, and older people admitted to the hospital may have a higher risk of self-neglect due to their deteriorating health conditions. This study aimed to translate, adapt and validate the Abrams geriatric self-neglect assessment scale (AGSS) among older Chinese people admitted to the hospital. METHODS: Data were derived from a cross-sectional survey of a convenience sample of 452 older people admitted to a general hospital. Exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) were used to examine the structural validity of the AGSS. Content validity, criterion validity, internal consistency reliability, and test-retest reliability were also conducted to assess the psychometric properties of the scale. RESULTS: EFA yielded a 6-item one-factor model, which was supported by CFA and explained 44.74% of the total variance. The internal consistency was acceptable (Cronbach α = 0.740), and the test-retest reliability with a 14-day interval was good (intraclass correlation coefficient, ICC = 0.966). Significantly positive correlations with the caregiver-rated elder self-neglect assessment scale (r = 0.648) supported the concurrent validity of the scale. Significant differences in scores between respondents with different ages, marital statuses, educational levels and numbers of chronic diseases demonstrated the discriminative validity. CONCLUSION: The Chinese version of the AGSS is an easy-to-use, reliable and valid measure with satisfactory psychometric properties. Future studies should recruit a more representative sample of older people in China to verify the applicability of the scale. IMPLICATIONS FOR PRACTICE: The Chinese version of the AGSS enables clinical staff to accurately screen for and assess elder self-neglect upon hospital admission, which can inform the development of specific interventions and assignment of additional guardianship to those at risk of elder self-neglect.

The Role of Socioeconomic Status, Family Resilience, and Social Support in Predicting Psychological Resilience Among Chinese Maintenance Hemodialysis Patients.

Objectives: Evidence regarding the possible influence of social factors on psychological resilience among maintenance hemodialysis patients is scarce. The aim of this study was to explore the relationship among socioeconomic status, family resilience, and social support, and psychological resilience among Chinese maintenance hemodialysis patients. Methods: This cross-sectional study was conducted in the hemodialysis centers of three comprehensive hospitals in China from September to December 2020 using convenience sampling. Two hundred fifty-eight patients receiving maintenance hemodialysis were investigated using a sociodemographic questionnaire, the Chinese version of the Medical Outcomes Study-Social Support Survey (MOS-SSS), Chinese Family Resilience Assessment Scale (C-FRAS), and Chinese version of the Conner and Davidson resilience scale (CD-RISC). Results: Maintenance hemodialysis patients reported a low level of physical resilience, with a score of (58.92 ± 15.27). Hierarchical linear regression analysis showed that education level (ß = 0.127, p = 0.018), maintenance of a positive outlook by the family (ß = 0.269, p = 0.001), positive social interaction support from the family (ß = 0.233, p = 0.002), and tangible support (ß = -0.135, p = 0.037) were significantly associated with psychological resilience. Conclusion: SES, family resilience and social support may be potential predictive factors of psychological resilience. Interventions to improve the family resilience and social support may be beneficial to promote the psychological resilience of Chinese maintenance hemodialysis patients.

Hmox1 promotes osteogenic differentiation at the expense of reduced adipogenic differentiation induced by BMP9 in C3H10T1/2 cells.

Mesenchymal stem cells (MSCs) are multipotent progenitors that can differentiate into a variety of cell types under proper stimuli. Bone morphogenetic protein 9 (BMP9) is able to simultaneously induce both adipogenic and osteogenic differentiation of MSCs although the regulatory molecules involved remain to be fully identified and characterized. Heme oxygenase 1 (Hmox1) plays an essential role not only in fat metabolism, but also in bone development. In the present study, we investigated the functional role of Hmox1 in BMP9-induced osteogenic/adipogenic differentiation in MSCs line C3H10T1/2 and probed the possible mechanism involved. We found that BMP9 promoted the endogenous expression of Hmox1 in C3H10T1/2 cells. Overexpression of Hmox1 or cobalt protoporphyrin (CoPP), an inducer of Hmox1, increased BMP9-induced osteogenic differentiation in vitro. Subcutaneous stem cell implantation in nude mice further confirmed that Hmox1 potentiated BMP9-induced ectopic bone formation in vivo. In contrast, Hmox1 reduced BMP9-induced adipogenic differentiation in C3H10T1/2 cells. Although had no obvious effect on BMP9-induced Smad1/5/8 phosphorylation, Hmox1 enhanced phosphorylation of p38, and AKT, while decreased phosphorylation of ERK1/2. Furthermore, Hmox1 increased total ß-catenin protein level, and promoted the nuclear translocation of ß-catenin in C3H10T1/2 cells. Taken together, our study strongly suggests that Hmox1 is likely to potentiate osteogenic differentiation and yet decrease adipogenic differentiation induced by BMP9 possibly through regulation of multiple signaling pathways.
