The Childbearing sense of coherence scale (CSOC-scale): development and validation.

BACKGROUND: the salutogenic theory is essential to explain an individual's ability to maintain health during the perinatal period. While previous studies mainly focused on the perspectives from a family-level orientation and a global orientation, the purpose of the present study was to develop and validate a scale, the childbearing sense of coherence scale (CSOC-scale) from the individual's perceptions of the stresses, resources, and meaningfulness of childbearing. METHODS: A total of 3 separate studies contributed to the development of the CSOC-scale between July 2022 and February 2023. In study 1, the initial item pool based on the conceptual framework of the childbearing sense of coherence and the salutogenic theory was developed. Delphi expert consultation was conducted to revise and improve items. Studies 2 and 3 were cross-sectional studies. In study 2, item analysis and explore factor analysis (EFA) (N = 351 for women, N = 256 for men) were used to screen items. In study 3, confirmatory factor analysis (CFA) and reliability analysis (N = 366 for women, N = 308 for men) were used to test the fit indices and reliability of the final scale. RESULTS: final analysis suggested the CSOC-scale includes three factors, consisting of 13 items. Confirmatory factor analysis demonstrated good model fit (χ2 = 157.448, df = 62, χ2/ df = 2.539, RMSEA = 0.065, CFI = 0.974, TLI = 0.968, SRMR = 0.029 for women; χ2 = 181.363, df = 62, χ2/ df = 2.925, RMSEA = 0.079, CFI = 0.968, TLI = 0.960, SRMR = 0.033 for men) and high factor loadings (from 0.751 to 0.929 for women; from 0.746 to 0.947 for men). Internal consistency (Cronbach's α ranging from 0.895 to 0.933 for women and 0.881 to 0.945 for men in three dimensions; Cronbach's α was 0.919 for women and 0.821 for men in the entire instrument) and split-half reliability (Spearman-Brown coefficients ranging from 0.876 to 0.921 for women and 0.841 to 0.937 for men in three dimensions; Spearman-Brown coefficient was 0.744 for women and 0.785 for men in the entire instrument) were excellent. CONCLUSIONS: the CSOC-scale has robust psychometric properties. It is reliable and valid in evaluating the childbearing sense of coherence in women and men during pregnancy. Utilisation of this scale can help healthcare professionals understand the health maintenance competencies of couples during the transition of parenthood and provide health promotion services from a salutogenic perspective.

Infertility psychological distress in women undergoing assisted reproductive treatment: A grounded theory study.

BACKGROUND: While there exists an ample body of research in international contexts focused on the characterization and quantification of infertility psychological distress, the level of scholarly scrutiny directed towards this phenomenon within the context of China remains scant. AIMS AND OBJECTIVES: To investigate the formation and developmental processes of psychological distress associated with infertility and infertility treatment among women within the Chinese cultural context and to construct a theoretical framework that elucidates this phenomenon. DESIGN: Qualitative approach with grounded theory methodology. METHODS: This study was conducted within the reproductive medicine department of a tertiary-level hospital located in central China from May to August 2023. Twenty-seven women who experienced infertility and underwent assisted reproductive treatment (ART) were interviewed. The interview sessions spanned durations ranging from 20 min to 1 h and 35 min. Data analysis included open coding, axial coding and selective coding. The study is reported using the COREQ checklist. RESULTS: The infertility psychological distress experienced by women undergoing ART is a socially constructed phenomenon influenced by a dynamic interplay of forces that construct and conciliate it. The formation and progression of infertility psychological distress are rooted in the process of self-construction. A Middle-Ranged Theory titled 'self-reconstruction under the dome of infertility and infertility treatment' (SUDIT theory) was developed to explain this phenomenon. Within this framework, infertility psychological distress manifests across three distinct phases under the gambling of the constructive force and conciliative force: (1) distress of disrupting the former self; (2) distress linked to the struggling present self; and (3) the renewed-self harmonized with distress. CONCLUSIONS: It is imperative for healthcare professionals and policymakers to acknowledge the socially constructed nature of infertility psychological distress, and proactively implement measures aimed at ameliorating it. PATIENT OR PUBLIC CONTRIBUTION: No patient or public contribution.

Development and validation of the Perceived Benefits of Team-Interaction Training Questionnaire (PBTITQ) among undergraduates.

BACKGROUND: The effectiveness of team-interaction training has been proven. However, there is a lack of objective and accurate evaluation tools for the impact and benefits of team-interaction training on participants. This study aims to develop and validate a tool for exploring undergraduates' perception of benefits in team-interaction. It can further insight into the perceived benefits of team-interaction training for undergraduates and evaluates the effectiveness of the course, and provides a reference point for the development of university team-interaction training courses. METHODS: This study was conducted in three stages. Phase 1 consisted of item generation: A theoretical framework was crafted based on social cognitive theory, self-efficacy theory, and sports performance models. Fifty-two items were generated based on the theoretical framework, participant interviews, and literature review. After Delphi consultation and pilot tests, 39 items moved on to Phase 2. Phase 2 consisted of forming a preliminary questionnaire: the contents to be included were selected through item analysis and exploratory factor analysis (EFA). A total of 40 classes were selected for EFA. After EFA, a three-factor structure with 25 items was formed. The third stage tested psychometric properties through confirmatory factor analysis (CFA), test-retest reliability, criterion-related validity, and internal consistency. RESULTS: The final PBTITQ consisted of 23 items, each rated from "1" (fully disagree) to "5" (fully agree). EFA and CFA supported the three-factor structure of PBTITQ, which included Cohesion, Communication, and Efficiency. The Cronbach's alpha of the PBTITQ was 0.90, the test-retest reliability was 0.88, and the split-half reliability was 0.81. PBTITQ significantly correlated with the GEQ (r = 0.808, p < 0.05) and the TDM (r = 0.796, p < 0.05). CONCLUSION: The PBTITQ is an effective tool for assessing the perceived benefits of team-interaction training among undergraduates.

The unmet needs of older adults living in nursing homes in Mainland China: a nation-wide observational study.

BACKGROUND: The unmet needs of older adults in nursing homes could result in their poor health status physically and psychologically. The aim of this study was to understand the characteristics of unmet needs of older adults residing in nursing homes in China, and to probe into the contributing factors. METHODS: In this cross-sectional design, the demographic and health status questionnaire, Modified Barthel Index, the Numerical Rating Scale for pain assessment, Geriatric Depression Scale, Camberwell Assessment of Need for the elderly were employed to survey older adults living in 38 nursing homes in 13 cities in China from July 2017 to June 2018 through a multi-stage, stratified sampling scheme. The Short Portable Mental Status Questionnaire was adopted to exclude participants with severe cognitive impairment. Aside from descriptive analysis, a raft of hierarchical logistic regression models were run by sequentially controlling for the independent variables at 5 levels (demographic characteristics, health status, pain, ADL, and depression), aiming to identify the influencing factors of the unmet needs of the residents. RESULTS: The effective sample size involved 2063 older adults (63.4% female versus 36.6% male), with a response rate of 98.5%. The median and inter-quartile range of the total needs and unmet needs of the sample was 3(1, 4) and 0(0, 1) respectively, with 122 older participants having more than 3 unmet needs (high unmet need category) versus 1922 older ones having ≤ 3 unmet needs (low unmet need category). The unmet needs of older adults in nursing homes mainly fell into social domains. Gender, religion, educational background, marital status, living condition before admission, room type, incomes, staffing, number of diseases, pain, Barthel Index, and depression were contributive to unmet needs of older adults in long-term care facilities in the final model that was adjusted for all levels of variables (all p < 0.05). CONCLUSION: Understanding the influencing factors of the unmet needs of older adults in long term care provides clues for healthcare professionals to offer better care for this population. System-level support to nursing homes and training of staff are highlighted. Plus, taking measures to beef up social connections for the older adults to meet their social needs was suggested.

Factors associated with child delivery expenditure during the transition to the national implementation of the two-child policy in China.

BACKGROUND: This study aimed to analyze the status of birthrates and the characteristics of child delivery expenditure under the Chinese two-child policy's transition period. We evaluated the socioeconomic factors associated with child delivery and provide evidence for decisions relating to health support for childbirth. METHODS: Child delivery expense data were obtained from 2015 to 2017 in Dalian, China. A total of 13,535 obstetric records were enrolled using stratified random sampling and the proportional probability to size method. First, we calculated the current curative expenditure of child delivery and health financing in childbirth costs based on the System of Health Accounts 2011 (SHA 2011). Second, univariate analysis of variance and generalized linear modeling were performed to examine factors associated with child delivery expenditure. Third, we classified the included hospitals into the county, district, and municipal hospitals and compared maternal characteristics between these categories. RESULTS: Overall, out-of-pocket payments accounted for more than 35% of the total expenditure on child delivery. Median (interquartile range) delivery expenditure at the county and district level hospitals [county-level: 5128.50 (3311.75-5769.00) CNY; district-level: 4064.00 (2824.00-6599.00) CNY] was higher than that at the municipal level hospitals: 3824.50 (2096.50-5908.00) CNY. The increase of child delivery expenditure was associated with an increased ratio of reimbursement, admissions to county and district level hospitals, cesarean sections, and length of stay, as well as a decline in average maternal age (p < 0.05). CONCLUSIONS: Health financing for childbirth expenditure was not rational during the transition period of the family planning policy in China. Higher delivery expenditure at county and district level hospitals may indicate variations in medical professionalism. Poorly managed hospitalization expenditure and/or nonstandard medical charges for childbirth, all of which may require the development of appropriate public health policies to regulate such emerging phenomena.

Multi-Step Phase Transitions of Mn3 O4 During Galvanostatic Lithiation: An In Situ Transmission Electron Microscopic Investigation.

For study of electrochemical reaction mechanisms at nanoscale, in situ electrochemical transmission electron microscopy (EC-TEM) exceeds many other methods due to its high temporal and spatial resolution. However, the limited amount of active materials used in previous in situ TEM studies prevents the model EC cells to operate in the constant-current (galvanostatic) charge/discharge mode that is required for accurate control of electrochemical processes. Herein, a new in situ EC-TEM technique is developed to investigate multi-step phase transitions of Mn3 O4 electrodes under the galvanostatic charge/discharge mode and constant-voltage discharge mode. In galvanostatic mode, the lithiation of Mn3 O4 undergoes multi-step phase transitions following a reaction pathway of Mn3 O4 + Li+ → LiMn3 O4 + Li+ → MnO + Li2 O → Mn + Li2 O. It is also found that lithium ions prefer to enter Mn3 O4 along the {101} direction to form LiMn3 O4 with the help of transitional boundary phase of Lix Mn3 O4 . These results are in sharp contrast to that obtained under a constant-voltage discharge mode, where only a single-step lithiation process of Mn3 O4 + Li+ → Mn + Li2 O is observed.

CD4(+) T cells from food allergy model are resistant to TCR-dependent apoptotic induction.

BACKGROUND: CD4(+) T cell polarization plays a critical role in the pathogenesis of allergy. How to modulate the skewed CD4(+) T cell polarization is less clear. The specific immunotherapy (SIT) is the only specific remedy for the treatment of allergic diseases; the therapeutic effect is to be improved. OBJECTIVES: This study aims to investigate the role of interleukin (IL)-18 in enhancing the therapeutic effect of SIT. METHODS: A peanut allergy mouse model was developed and treated with SIT or/and IL-18. CD4(+) T cell apoptosis was assessed by flow cytometry. The expression of Fas ligand (FasL) was observed by quantitative real time RT-PCR and Western blotting. Interferon-γ in the culture medium was determined by enzyme-linked immunosorbent assay. The fasL gene promoter methylation in CD4(+) T cells was assessed by methylation specific PCR. RESULTS: The results showed that lower levels of IL-18 were detected in allergic mice; administration of IL-18 significantly enhanced the therapeutic effect of SIT on suppressing the allergic inflammation in the mouse intestine. In the cell culture studies, IL-18 increased the TCR-dependent CD4(+) T cell apoptosis, the expression of FasL in CD4(+) T cells, the production of Interferon-γ and the demethylation of the FasL promoter in CD4(+) T cells. CONCLUSIONS: Administration of IL-18 enhances the effect of SIT on suppressing allergic inflammation in the mouse intestine via enhancing the TCR-dependent CD4(+) T cell apoptosis.

Nocardamine mitigates cellular dysfunction induced by oxidative stress in periodontal ligament stem cells.

BACKGROUND: The role of periodontal ligament stem cells (PDLSCs) in repairing periodontal destruction is crucial, but their functions can be impaired by excessive oxidative stress (OS). Nocardamine (NOCA), a cyclic siderophore, has been shown to possess anti-cancer and anti-bacterial properties. This study aimed to investigate the protective mechanisms of NOCA against OS-induced cellular dysfunction in PDLSCs. METHODS: The cytotoxicity of NOCA on PDLSCs was assessed using a CCK-8 assay. PDLSCs were then treated with hydrogen peroxide (H2O2) to induce OS. ROS levels, cell viability, and antioxidant factor expression were analyzed using relevant kits after treatment. Small molecule inhibitors U0126 and XAV-939 were employed to block ERK signaling and Wnt pathways respectively. Osteogenic differentiation was assessed using alkaline phosphatase (ALP) activity staining and Alizarin Red S (ARS) staining of mineralized nodules. Expression levels of osteogenic gene markers and ERK pathway were determined via real-time quantitative polymerase chain reaction (RT-qPCR) or western blot (WB) analysis. ß-catenin nuclear localization was examined by western blotting and confocal microscopy. RESULTS: NOCA exhibited no significant cytotoxicity at concentrations below 20 µM and effectively inhibited H2O2-induced OS in PDLSCs. NOCA also restored ALP activity, mineralized nodule formation, and the expression of osteogenic markers in H2O2-stimulated PDLSCs. Mechanistically, NOCA increased p-ERK level and promoted ß-catenin translocation into the nucleus; however, blocking ERK pathway disrupted the osteogenic protection provided by NOCA and impaired its ability to induce ß-catenin nuclear translocation under OS conditions in PDLSCs. CONCLUSIONS: NOCA protected PDLSCs against H2O2-induced OS and effectively restored impaired osteogenic differentiation in PDLSCs by modulating the ERK/Wnt signaling pathway.

How heavy is the medical expense burden among the older adults and what are the contributing factors? A literature review and problem-based analysis.

In recent years, the aging population and increasing medical expenses among the older adults have emerged as significant public health concerns. National governments must conduct medical expense accounting and implement measures to reduce the burden of medical costs on the older population. However, limited studies have focused on total medical expenditure from a macro perspective, with many researches exploring individual medical expenses from different perspectives. This review introduces the trend of population aging and its impact on health cost change, reviews research on the medical expense burden of the older population and contributing factors, and points out underlying problems and limitations of current studies. Based on the present studies, the review emphasizes the necessity of medical expense accounting and analyzes the medical expense burden of the older population. Future studies should explore the impacts of medical insurance funds and health service system reforms on reducing medical expenses and developing a supporting medical insurance reform plan.

Deficiency of NARFL increases transcription of NADPH oxidases and ROS production impairing the function of endothelial cells.

AIMS: Nuclear prelamin A recognition factor-like (NARFL) is involved in cytosolic iron­sulfur (FeS) protein biogenesis and cellular defense against oxidative stress. Previous study reported that increased oxidative stress and subintestinal vessel (SIV) malformation in narfl knockout zebrafish. However, the underlying mechanism of oxidative stress caused by NARFL deficiency remains unclear. The present study was sought to investigate the function of NARFL in endothelial cells. METHODS: NARFL knockdown assay was performed in two cell lines and NADPH oxidase (Nox) were measured using Western blotting. Nox inhibitors were selected for assessing the potential sources of reactive oxygen species (ROS) generation. Cell migration was detected using wound healing assay and transwell assay. Cell cycle was analyzed using flow cytometry. Promoter activity assay and Chromatin immunoprecipitation (ChIP) assay were chosen for investigating the molecular mechanism of Nox transcription. RESULTS: NARFL deficiency resulted in upregulated expressions of Nox2, Nox4, and p47phox and increased ROS levels in endothelial cells. Nox2 knockdown reversed the effects and improved endothelial dysfunctions caused by NARFL deficiency. ChIP experiments revealed that NARFL knockdown increased the recruitment of RNA polymerase II and modification of histones at the promoter sites of Nox2 and Nox4. CONCLUSION: NARFL knockdown induced the transcriptional activation of Nox2 and Nox4, which resulted in increased ROS levels and impaired endothelial functions.

Medical expenditure of women during pregnancy, childbirth and puerperium at the beginning of China's universal two-child policy enactment: a population-based retrospective study.

OBJECTIVES: To describe and explore women's medical expenditures during pregnancy, childbirth and puerperium at the beginning of the universal two-child policy enactment in China. DESIGN: Population-based retrospective study. SETTING: Dalian, China. PARTICIPANTS: Under the System of Health Accounts 2011 framework, the macroscopic dataset was obtained from the annual report at the provincial and municipal levels in China. The research sample incorporated 65 535 inpatient and outpatient records matching International Classification of Diseases, 10th Revision codes O00-O99 in Dalian city from 2015 through 2017. PRIMARY AND SECONDARY OUTCOME MEASURES: The study delineates women's current curative expenditure (CCE) during pregnancy, childbirth and puerperium at the beginning of the universal two-child policy in China. The temporal changes of medical expenditure of women during pregnancy, childbirth and puerperium at the beginning of China's universal two-child policy enactment were assessed. The generalised linear model and structural equation model were used to test the association between medical expenditure and study variables. RESULTS: Unlike the inverted V-shaped trend in the number of live newborns in Dalian over the 3 studied years, CCE on pregnancy, childbirth and puerperium dipped slightly in 2016 (¥260.29 million) from 2015 (¥263.28 million) and saw a surge in 2017 (¥288.65 million). The ratio of out-of-pocket payment/CCE reduced year by year. There was a rapid increase in CCE in women older than 35 years since 2016. Length of stay mediated the relationship between hospital level, year, age, reimbursement ratio and medical expenditure. CONCLUSIONS: The rise in CCE on pregnancy, delivery and puerperium lagged 1 year behind the surge of newborns at the beginning of China's universal two-child policy. Length of stay acted as a crucial mediator driving up maternal medical expenditure. Reducing medical expenditure by shortening the length of stay could be a feasible way to effectively address the issue of cost in women during pregnancy, childbirth and puerperium.

Screening of Anti-Inflammatory Components of Qin Jin Hua Tan Tang by a Multivariate Statistical Analysis Approach for Spectrum-Effect Relationships.

Qing Jin Hua Tan Tang (QJHTT) exerts therapeutic effects in patients with chronic obstructive pulmonary disease (COPD) by alleviating inflammation. However, the anti-inflammatory components of QJHTT have not yet been reported. Our study aimed to screen the active anti-inflammatory components of QJHTT using a multivariate statistical analysis approach for spectrum-effect relationships. Different polar fractions of QJHTT were prepared using ethanol, ethyl acetate, and n-butanol to analyze the phytochemical components. Phytochemical fingerprints were generated using ultrahigh-performance liquid chromatography. In total, 24 peaks were observed in ten batches of QJHTT extracts. The anti-inflammatory activity was evaluated using a xylene-induced ear-swelling mouse model. Additionally, the spectrum-effect relationship between the relative areas of the 24 peaks and pharmacological activity was investigated using multivariate statistical analysis. The potential anti-inflammatory ingredients obtained from the screening (multivariate statistical analysis) will be validated for their anti-inflammatory effects and mechanisms utilizing a lipopolysaccharide-induced macrophage inflammation model. QJHTT ethanol extract 1 exhibited good anti-inflammatory activity. Peaks 11, 12, 13, 14, and 16, which were closely correlated with anti-inflammatory activity, were identified as meranzin, baicalin, baicalein, chrysin-7-O-ß-D-glucuronide, and wogonoside, respectively. The anti-inflammatory activities of meranzin, baicalin, baicalein, and wogonoside were verified in vitro. These four bioactive components significantly inhibited the secretion of inflammatory factors in the lipopolysaccharide-stimulated macrophage cell line. This research successfully screened the QJHTT anti-inflammatory active ingredient group. Meranzin, baicalin, baicalein, chrysin-7-O-ß-D-glucuronide, and wogonoside were predicted to be the anti-inflammatory active ingredient groups of QJHTT.

Specific Ag-guiding nano-vaccines attenuate neutrophil-dominant allergic asthma.

Polymorphonuclear neutrophils (PMN) are one fraction of the major inflammatory cells in allergic asthma (asthma, in short); the role of PMN in the asthma pathogenesis is not fully understood yet. This study aims to investigate the effects of specific Ag-guiding exosomes on suppressing the neutrophil-dominant airway inflammation. In this study, BALB/c mice were immunized with ovalbumin plus complete Freund adjuvant to induce an asthma model featured with neutrophil-dominant lung inflammation. The Ag specific PMN (sPMN)-targeting exosomes (tExo), that were exosomes carrying a complex of specific Ag/anti-CD64 Ab and Fas ligand, were constructed to be used to alleviate neutrophilic asthma in mice. We found that sPMNs were the major cellular component in bronchoalveolar lavage fluid (BALF) in asthma mice, while less than 3% PMNs in naive control mice. The sPMNs expressed higher levels of CD64, which formed complexes with Ag-specific IgG (sIgG). The sIgG/CD64 complex-carrying PMNs could be activated upon exposing to specific Ags. Exposure to tExos induced Ag-specific PMNs apoptosis. Administration of tExos efficiently suppressed experimental asthma. We conclude that a fraction of sPMN was identified in the airway of asthma mice. The sPMNs could be activated upon exposure to specific Ags. tExos could induce sPMNs apoptosis, that show the translational potential in the treatment of asthma.

Interpretation of China's 2017 health expenditure: a latent profile analysis of panel data.

OBJECTIVE: To explore the latent structure of health financing and the institutional distribution of health expenditure (focused on hospital expenditure) in provinces, autonomous regions and municipalities of mainland China, and to examine how these profiles may be related to their externalising and internalising characteristics. STUDY DESIGN: The study used panel data harvested from the China National Health Accounts Report 2018. METHODS: Mainland China's provincial data on health expenditure in 2017 was studied. A latent profile analysis was conducted to identify health financing and hospital health expenditure profiles in China. Additionally, rank-sum tests were used to understand the difference of socioeconomic indicators between subgroups. RESULTS: A best-fitting three-profile solution for per capita health financing was identified, with government health expenditure (χ2=10.137, p=0.006) and social health expenditure (χ2=6.899, p=0.032) varying significantly by profiles. Health expenditure in hospitals was subject to a two-profile solution with health expenditure flow to urban hospitals, county hospitals and community health service centres having significant differences between the two profiles (p<0.001). CONCLUSIONS: Per capita health financing and health expenditure spent in hospitals have discrepant socioeconomic characteristics in different profiles, which may be attributed to macroeconomic factors and government policies. The study provided new and explicit ideas for health financing and health policy regulation in China.

Epidemiological analysis of the early 38 fatalities in Hubei, China, of the coronavirus disease 2019.

BACKGROUND: Since the emergence of coronavirus disease 2019 (COVID-19) in Hubei province of China by the end of 2019, it has burned its way across the globe, resulting in a still fast-growing death toll that far exceeded those from severe acute respiratory syndrome (SARS) in less than two months. As there is a paucity of evidence on which population is more likely to progress into severe conditions among cases, we looked into the first cluster of death cases, aiming to add to current evidence and reduce panic among the population. METHODS: We prospectively collected the demographic and clinical data of the first 38 fatalities whose information was made public by the Health Commission of Hubei province and the official Weibo account of China Central Television news center, starting from 9 January through 24 January 2020. The death cases were described from four aspects (gender and age characteristics, underlying diseases, the time course of death, symptoms at the incipience of illness and hospital admission). RESULTS: Among the 38 fatalities, 71.05% were male, and 28.95% were female, with the median age of 70 years (interquartile range (IQR) = 65-81). Persons aged 66-75 made up the largest share. Twenty-five cases had a history of chronic diseases. The median time between the first symptoms and death was 12.50 days (IQR = 10.00-16.25), while the median time between the admission and death was 8.50 (IQR = 5.00-12.00) days. In persons aged over 56 years, the time between the first symptoms and death decreased with age, and so did the time between the admission and death, though the latter increased again in persons aged over 85 years. The major first symptoms included fever (52.63%), cough (31.58%), dyspnea (23.68%), myalgia and fatigue (15.79%). CONCLUSIONS: Among the death cases, persons with underlying diseases and aged over 65 made up the majority. The time between the first symptoms and death decreased with the advanced age. In all the age groups, males dominated the fatalities.

Nurses' Perceptions of Factors Influencing Elder Self-neglect: A Qualitative Study.

PURPOSE: Elder self-neglect is a global public health issue and should be taken seriously at large. Nurses, usually working directly with elderly patients, have a better understanding of what factors may cause elder self-neglect. In this qualitative study, we explored the influencing factors of elder self-neglect from the perception of nurses in the context of Chinese culture. METHODS: Face-to-face, in-depth interviews were conducted from November 2018 to December 2018. Purposive sampling was used. Twenty one participants recruited from eight geriatric wards of a general hospital located in Wuhan were interviewed. A content analysis of qualitative nature was performed to analyze the data. RESULTS: Our conceptual model illustrated the findings based on the three themes of the conflict between personal recognition and social judgment, the choice between current needs and individual beliefs, as well as the compromise between insufficient abilities and limited resources. CONCLUSION: Nurses together with family members and social workers can help older adults improve their awareness of self-neglect to bridge the gap with social judgment, learn to focus on their own needs, as well as seek as much support as possible. Nurses should also respect the autonomy and self-determination of elder self-neglecters because self-neglect is related to older adults' values. Furthermore, larger studies are needed to quantitatively test and refine the model.

Effect of pain on depression among nursing home residents: Serial mediation of perceived social support and self-rated health. A cross-sectional study.

AIM: The aim of this study was to investigate how perceived social support and self-rated health together could mediate the relationship between pain and depression among Chinese nursing home residents with pain. METHODS: The study was conducted in 38 nursing homes in 13 cities in China. A convenience sample of 2154 older adults responded to the questionnaire survey. A mediation analysis was performed on the data of 990 participants with pain. The data were collected by a questionnaire consisting of socio-economic and demographic characteristics, the Geriatric Depression Scale-15, the Multidimensional Scale of Perceived Social Support, Self-rated Health Scale and the Numerical Rating Scale of pain. The sample was subdivided by sex. Descriptive analysis, t-tests, chi-squared tests, Mann-Whitney U-tests, Spearman correlation analyses and the bootstrap method were used to analyze data. RESULTS: The prevalence rate of pain and depression among nursing home residents were 46.0% and 20.7% respectively. Pain, perceived social support and self-rated health were all significantly correlated with depression (r = 0.217, P < 0.01; r = -0.216, P < 0.01; r = 0.385, P < 0.01, respectively). Perceived social support and self-rated health independently and in series partly explained the relationship between pain and depression. CONCLUSIONS: The results of the study showed that pain was associated with low perceived social support first, and then poor self-rated health, which was in turn related to the development of depression among nursing home residents with pain. For nursing home residents, perceived social support and self-rated health as an internal resource can affect the ability to overcome the suffering of pain and reduce the level of depression.

Inhibition of Bcl2L12 Attenuates Eosinophilia-Related Inflammation in the Heart.

Background: The eosinophilic inflammation plays a critical role in myocarditis (Mcd); its underlying mechanism remains to be further elucidated. This study aims to investigate the role of Bcl2-like protein 12 (Bcl2L12) in inducing the defects of apoptosis in eosinophils (Eos) of the heart tissues. Methods: Human explant heart samples were collected. Eosinophilia and myocarditis (Mcd)-like inflammation were induced in the mouse heart by immunizing with murine cardiac α-myosin heavy chain (MyHCα) peptides. Results: Markedly more Eos were observed in heart tissues from patients with Mcd than those from patients with dilated cardiomyopathy. Eos isolated from Mcd hearts showed the signs of apoptosis defects. The Eo counts in the Mcd heart tissues were positively correlated with the Bcl2L12 expression in Eos isolated from the heart tissues. Exposure to interleukin 5 in the culture induced the expression of Bcl2L12 in Eos. Bcl2L12 bound c-Myc, the transcription factor of Fas ligand (FasL), to prevent c-Myc from binding to the FasL promoter, to restrict the FasL gene transcription in Eos. Inhibition of Bcl2L12 prevented the induction of eosinophilia and Mcd-like inflammation in the mouse heart. Conclusions: The Bcl2L12 expression contributes to apoptosis defects in Eos of the Mcd heart. Blocking Bcl2L12 prevents the eosinophilia induction and alleviates Mcd-like inflammation in mice.

Expression Levels of MicroRNA-125b in Serum Exosomes of Patients with Asthma of Different Severity and its Diagnostic Significance.

BACKGROUND: This study aimed to investigate the expression levels of microRNA (miRNA)-125b in serum exosomes and its diagnostic efficacy for asthma severity. METHODS: The study included 80 patients with untreated asthma and 80 healthy volunteers. The patients were divided into 4 groups according to disease severity: 20 with the intermittent state, 20 with the mildly persistent state, 20 with the moderately persistent state, and 20 with the severely persistent state. The expression levels of miRNA-125b in serum exosomes of each group were detected using a quantitative polymerase chain reaction and compared. The Spearman correlation analysis was used to study the correlation between the expression levels of miRNA-125b in serum exosomes and asthma severity. The diagnostic efficacy of the expression levels of miRNA-125b in exosomes for asthma severity was evaluated using the Receiver Operating Characteristic (ROC) curve. RESULTS: The expression levels of miRNA-125b in serum exosomes of patients with intermittent, mildly persistent, moderately persistent, and severely persistent asthma were all higher than those in the healthy control group, with statistically significant differences. The expression levels of miRNA-125b were also statistically significantly different among patients in each group. The Spearman correlation analysis showed a positive correlation of the relative expression of miRNA-125b in serum exosomes with asthma severity. The area under the ROC curve of the diagnostic efficacy of miRNA-125b in serum exosomes for patients with intermittent, mildly, moderately, and severely persistent asthma was 0.7770, 0.8573, 0.9111, and 0.9995, respectively. CONCLUSION: The expression levels of miRNA-125b in serum exosomes had a high diagnostic efficacy and might serve as a noninvasive diagnostic marker for asthma severity.
