Dose‒Response Effects of Patient Engagement on Anxiety and Depression in a Cognitive-Behavioral Intervention: Secondary Analysis of a Pilot Randomized Controlled Trial and a Clinical Controlled Trial.

Understanding the dose‒response relationship between patient engagement in cognitive behavioral therapy (CBT) and health outcomes is critical for developing and implementing effective CBT programs. In studies of CBT interventions, patient engagement is measured only at a single time point, and outcomes are typically assessed before and after the intervention. Examination of the dose‒response relationship between patient engagement in CBT and outcomes is limited. It is unclear whether a dose‒response relationship exists between patient engagement in on-site CBT intervention and anxiety and depression in people living with HIV (PLWH). If present, does this dose‒response relationship occur early or later in the intervention? This study aimed to address this gap by examining the dose‒response relationships between patient engagement and anxiety and depression in CBT interventions among PLWH. Utilizing data from a pilot randomized trial (10 participants) and a clinical controlled trial (70 participants), our secondary analysis spans baseline, 3-month, and 6-month assessments. Both trials implemented the nurse-led CBT intervention. Cluster analysis identified two groups based on on-site attendance and WeChat activity. Patients with good adherence (6-10 times) of on-site attendance exhibited significantly lower anxiety and depression scores at 3 months (ß = 1.220, P = 0.047; ß = 1.270, P = 0.019), with no significant differences observed at 6 months. WeChat activity did not significantly influence anxiety or depression scores. The findings highlight a significant short-term dose‒response relationship, endorsing nurse-led CBT interventions for mental health in PLWH. Organizational strategies should focus on incentivizing and facilitating patient engagement, particularly through enhancing WeChat features.

Phenotypic characteristics and immune response of Procypris merus following challenge with aquatic isolate of Klebsiella pneumoniae.

Currently, aquaculture is a relatively mature industry; however, disease problems are continuously threatening the industry and hindering its development to a certain extent. Klebsiella pneumoniae is one of the zoonotic bacteria widely present in different hosts and has caused some degree of harm to the aquaculture industry, posing a potential threat to the water environment and indirectly also affecting human food safety issues. In this study, K. pneumoniae was isolated from the aquaculture environment, named as ELD, and subjected to pathogenic and immunological related studies. The results of the study showed that the strain carries at least four virulence-related genes, magA, wabG, ureA and uge, and has developed resistance to at least seven antibacterial drugs, such as amoxicillin, doxycycline, rifampicin, and so on. Moreover, the strain is highly pathogenic and is capable of causing systemic clinical foci in Procypris merus. In addition, after infection with K. pneumoniae, the expression of IL-1ß, IL-8, HSP70 and C2 was upregulated in P. merus as a whole, whereas the expression of TNF-α did not change significantly in any of the tissues, which might be a kind of immune response of P. merus against K. pneumoniae infection. This study provides an important theoretical basis for the in-depth exploration of the pathogenic mechanism of K. pneumoniae in fish and the immune response that occurs after the disease is contracted in fish, as well as theoretical support for the development of effective preventive and therapeutic strategies against K. pneumoniae-infected aquatic animals in the future.

CST2 promotes cell proliferation and regulates cell cycle by activating Wnt-ß-catenin signalling pathway in serous ovarian cancer.

BACKGROUND: Cystatin SA (CST2) plays multiple roles in different types of malignant tumours; however, its role in serous ovarian cancer (SOC) remains unclear. Therefore, we aimed to investigate the expression levels, survival outcomes, immune cell infiltration, proliferation, cell cycle, and underlying molecular mechanisms associated with the CST2 signature in SOC. METHODS: The Cancer Genome Atlas database was used to acquire clinical information and CST2 expression profiles from patients with SOC. Wilcoxon rank-sum tests were used to compare CST2 expression levels between SOC and normal ovarian tissues. A prognostic assessment of CST2 was conducted using Cox regression analysis and the Kaplan-Meier method. Differentially expressed genes were identified using functional enrichment analysis. Immune cell infiltration was examined using a single-sample gene set enrichment analysis. Cell cycle characteristics and proliferation were assessed using a colony formation assay, flow cytometry, and a cell counting kit-8 assay. Western blots and quantitative reverse transcription PCR analyses were employed to examine CST2 expressions and related genes involved in the cell cycle and the Wnt-ß-catenin signalling pathway. RESULTS: Our findings revealed significant upregulation of CST2 in SOC, and elevated CST2 expression was correlated with advanced clinicopathological characteristics and unfavourable prognoses. Pathway enrichment analysis highlighted the association between the cell cycle and the Wnt signalling pathway. Moreover, increased CST2 levels were positively correlated with immune cell infiltration. Functionally, CST2 played vital roles in promoting cell proliferation, orchestrating the G1-to-S phase transition, and driving malignant SOC progression through activating the Wnt-ß-catenin signalling pathway. CONCLUSIONS: The elevated expression of CST2 may be related to the occurrence and progression of SOC by activating the Wnt-ß-catenin pathway. Additionally, our findings suggest that CST2 is a promising novel biomarker with potential applications in therapeutic, prognostic, and diagnostic strategies for SOC.

Serous ovarian cancer is a type of gynecological malignant tumour with high mortality rates. Understanding this disease is crucial for improving treatments and enhancing patient survival. In our study, we investigated a protein called CST2 and its role in serous ovarian cancer. We found that CST2 levels vary among patients and are associated with the progression of cancer and the prognosis of the patient, which could be valuable for future diagnosis and treatment strategies. However, further research is needed to validate these findings. Despite its limitations, our findings suggest that CST2 holds promise as a potential biomarker for detecting serous ovarian cancer and as a therapeutic target in the management of patients with this type of cancer.

Identification of ISG15 in golden pompano, Trachinotus ovatus, and its role in virus and bacteria infections.

Interferon (IFN)-stimulated gene product 15 (ISG15) is a ubiquitin-like protein critical for the control of microbial infections. Golden pompano, Trachinotus ovatus is one of the precious marine economic fish in the southern coast of China, always suffering from viruses, bacteria, and parasite infections. To date, the roles of golden pompano genes involved in viral and bacterial infections, especially IFN-related genes remained largely unknown. To identify the interferon system genes of golden pompano and explore their function, in this study, the ISG15 homolog (ToISG15) was cloned from golden pompano, and its role in response to grouper iridovirus (SGIV), nervous necrosis virus (NNV), and Aeromonas hydrophila infection was investigated. The whole ORF of ToISG15 was composed of 465 bp and encoded a polypeptide of 154 amino acids with different identity with the known ISG15 homologs from other fish species. Two conserved ubiquitin-like (UBL) domains and an Ub-conjugation domain (LRGG) were found in ToISG15 sequence. Expression analysis showed that ToISG15 was located mainly in the cytoplasm of golden pompano cells, and dramatically induced following SGIV, Aeromonas hydrophila, or poly I:C treatment, but little change was observed when NNV infection. Overexpression of ToISG15 in vitro significantly inhibited the replication of SGIV and NNV. Interestingly, ToISG15 possessed the ability to restrain the growth of Aeromonas hydrophila. Furthermore, To-ISG15 overexpression enhanced the expression of IFNc, IFNh, IRF3, IRF7, and viperin genes as well as, to a lesser extent, the IL-6 gene. Taken together, our results demonstrated the antiviral and antibacterial effect of To-ISG15, shedding light on the evolutionary conservation of ISG15 in the immune response to microbial infection.

Omics analysis revealed the possible mechanism of streptococcus disease outbreak in tilapia under high temperature.

High temperature is a main cause to result in the outbreak of tilapia streptococcal disease. However, the underlying mechanisms are not well understood. In this study, we first confirmed that tilapia infected with Streptococcus agalactiae (S. agalactiae) had a higher mortality at high temperature (35 °C) than that at normal temperature (28 °C). Subsequently, the effects of high temperature on gene expression pattern of S. agalactiae and intestinal microbiota of tilapia were respectively detected by RNA-seq and 16S rDNA sequencing. RNA-seq identified 357 differentially expressed genes (DEGs) in S. agalactiae cultured at 28 °C and 35 °C. GO and KEGG analysis showed that these DEGs were highly involved in metabolic processes, including glucose, lipid and amino acid metabolisms, which indicates that S. agalactiae have stronger vitality and are likely to be more infectious under high temperature. Microbiota analysis revealed that high temperature could influence the bacterial community composition of tilapia intestine, accompanied by changes in intestinal structure. Compared to feed at 28 °C, the total bacterial species as well as pathogens, such as norank_f__Rhizobiales_Incertae_Sedis, Pseudorhodoplanes, Ancylobacter, in tilapia intestine were significantly increased at 35 °C, which may weaken the immune resistance of tilapia. Taken together, our results suggest that high temperature evoked tilapia susceptible to S. agalactiae should be the combined effect of enhanced S. agalactiae metabolism and dysregulated tilapia intestinal microbiota.

Usability Evaluation of a Knowledge Graph-Based Dementia Care Intelligent Recommender System: Mixed Methods Study.

BACKGROUND: Knowledge graph-based recommender systems offer the possibility of meeting the personalized needs of people with dementia and their caregivers. However, the usability of such a recommender system remains unknown. OBJECTIVE: This study aimed to evaluate the usability of a knowledge graph-based dementia care intelligent recommender system (DCIRS). METHODS: We used a convergent mixed methods design to conduct the usability evaluation, including the collection of quantitative and qualitative data. Participants were recruited through social media advertisements. After 2 weeks of DCIRS use, feedback was collected with the Computer System Usability Questionnaire and semistructured interviews. Descriptive statistics were used to describe sociodemographic characteristics and questionnaire scores. Qualitative data were analyzed systematically using inductive thematic analysis. RESULTS: A total of 56 caregivers were recruited. Quantitative data suggested that the DCIRS was easy for caregivers to use, and the mean questionnaire score was 2.14. Qualitative data showed that caregivers generally believed that the content of the DCIRS was professional, easy to understand, and instructive, and could meet users' personalized needs; they were willing to continue to use it. However, the DCIRS also had some shortcomings. Functions that enable interactions between professionals and caregivers and that provide caregiver support and resource recommendations might be added to improve the system's usability. CONCLUSIONS: The recommender system provides a solution to meet the personalized needs of people with dementia and their caregivers and has the potential to substantially improve health outcomes. The next step will be to optimize and update the recommender system based on caregivers' suggestions and evaluate the effect of the application.

Research misconduct knowledge and associated factors among nurses in China: A national cross-sectional survey.

AIM: To measure the knowledge level of research misconduct and explore its associated factors among nurses. BACKGROUND: Engagement in research misconduct by nurses may transfer to professional misconduct in the clinical setting, thereby jeopardizing the quality of patient care. We still know little about the research misconduct situation among nurses. Previous attempts also hardly reflected participants' real knowledge level of research misconduct. METHODS: We applied multistage sampling (province, hospital, and participants) in this cross-sectional survey, and recruited 4112 nurses from 200 tertiary hospitals in 25 provinces. RESULTS: The average knowledge score of the participants was 15.99 ± 5.79. Associated factors of scientific misconduct knowledge score included career situation, educational level, fertility status, research activities index, and perceived consequences for research misconduct. CONCLUSION: It is urgent and necessary to design continuing research integrity training for nurses. Hospital managers and policy-makers should pay more attention to key trainees, including newcomers, nurses from less developed groups and institutions, and those from clinical departments. Training designers should also consider how to help nurses with offspring balance their family and work, and should not neglect the training for nurses with extensive research experience. In addition to conveying knowledge and information, the training can integrate cognitive education of research misconduct to improve the effect.

Assessing psychological symptom networks related to HIV-positive duration among people living with HIV: a network analysis.

This study aims to explore and visualize relationships among multiple psychological symptoms among people living with HIV (PLWH) with different HIV-positive durations and to compare centrality indices and densities of psychological symptom networks. We used subsets of data collected from five designated HIV/AIDS hospitals in China. Networks were constructed among 16 psychological symptoms. Centrality properties, including strength and closeness, were adopted to describe relationships among symptoms. The results showed that PLWH with longer HIV-positive durations had denser emotional networks, which indicated that they had more emotional neuroticism than their newly diagnosed counterparts. Sadness, self-abasement, and self-loathing were the most central psychological symptoms across different HIV-positive durations. Our study suggests the need to provide psychosocial support services targeting PLWH according to changing symptom severity and neuroticism trajectories. Interventions should focus on increasing empathy for PLWH and enhancing the ability to consider the situation from different perspectives to avoid the development of neuroticism in long-term survivors.

Psychometric properties of self-reported measures of health-related quality of life in people living with HIV: a systematic review.

OBJECTIVE: To identify and assess the psychometric properties of patient-reported outcome measures (PROMs) of health-related quality of life (HRQoL) in people living with HIV (PLWH). METHODS: Nine databases were searched from January 1996 to October 2020. Methodological quality was assessed by using the Consensus-based Standards for the Selection of Health Measurement Instruments (COSMIN) Risk of Bias Checklist. We used the COSMIN criteria to summarize and rate the psychometric properties of each PROM. A modified Grading, Recommendations, Assessment, Development, and Evaluation (GRADE) system was used to assess the certainty of evidence. RESULTS: Sixty-nine studies reported on the psychometric properties of 30 identified instruments. All studies were considered to have adequate methodological quality in terms of content validity, construct validity, and internal consistency. Limited information was retrieved on cross-cultural validity, criterion validity, reliability, hypothesis testing, and responsiveness. High-quality evidence on psychometric properties was provided for the Medical Outcomes Study HIV Health Survey (MOS-HIV), the brief version of the World Health Organization's Quality of Life Instrument in HIV Infection (WHOQoL-HIV-BREF), 36-Item Short Form Survey (SF-36), Multidimensional Quality of Life Questionnaire for Persons with HIV/AIDS (MQoL-HIV), and WHOQoL-HIV. CONCLUSIONS: The findings from the included studies highlighted that among HIV-specific and generic HRQoL PROMs, MOS-HIV, WHOQoL-HIV-BREF, SF-36, MQoL-HIV, and WHOQoL-HIV are strongly recommended to evaluate HRQoL in PLWH in research and clinics based on the specific aims of assessments and the response burden for participants.

Sleep satisfaction and cognitive complaints in Chinese middle-aged and older persons living with HIV: the mediating role of anxiety and fatigue.

Middle-aged and older persons living with HIV (PLWH) suffer from sleep distress and cognitive disorders due to HIV infection and aging. We aim to explore the relationship between sleep satisfaction and cognitive complaints, and the mediating role of anxiety and fatigue in this relationship among middle-aged and older PLWH. We used data from a multicenter cross-sectional study in China (Shanghai, Kunming, Nanning, Hengyang, and Changning) conducted in 2017. The data analysis included 435 PLWH aged 45 years and over. Multiple linear regression models showed that worse sleep satisfaction was significantly associated with lower cognitive complaints after controlling for anxiety, fatigue, demographic variables, and clinical variables (ß = -0.246, p < 0.01). Both anxiety and fatigue were significant partial mediators in the relationship between sleep satisfaction and cognitive complaints. The serial multiple mediation models of sleep satisfaction-anxiety (M1)-fatigue (M2)-cognitive complaints were supported and the alternative model of sleep satisfaction-fatigue (M2)-anxiety (M1)-cognitive complaints were both supported. Our study indicates that it is important to improve sleep quality to promote cognitive function among Chinese middle-aged and older PLWH. Prevention and treatment programs for sleep satisfaction and cognitive function should include the assessment and reduction of fatigue and anxiety.

Perceived discrimination and mental health symptoms among persons living with HIV in China: the mediating role of social isolation and loneliness.

Perceived discrimination is significantly associated with mental health symptoms among persons living with HIV (PLWH). However, little is known about the factors mediating this relationship. We aimed to examine the mediating role of social isolation and loneliness in the association between perceived discrimination and mental health symptoms among PLWH. A multicenter (Shanghai, Kunming, Nanning, Hengyang, and Changning in China) cross-sectional study was conducted in 2017. Data from 883 PLWH were used for statistical analysis. Perceived discrimination, mental health symptoms, loneliness and social isolation were assessed through self-report questionnaires. Structural equation modeling (SEM) showed a satisfactory model fit (CMIN/DF = 2.676, GFI = 0.998, CFI = 0.997, NFI = 0.995, TLI = 0.985, RMSEA = 0.044 [0.000, 0.090]) and a significant total indirect effect (ß = 0.058, SE = 0.009, Z = 6.444, p < 0.01). Both loneliness (ß = 0.042, SE = 0.008, Z = -5.250, p < 0.01) and social isolation (ß = 0.016, SE = 0.004, Z = -4.000, p < 0.01) were determined to be significant mediators of the association between perceived discrimination and mental health symptoms. Interventions that combat loneliness and social isolation may help ameliorate the adverse consequences of perceived discrimination on mental health.

Experience of chronic noncommunicable disease in people living with HIV: a systematic review and meta-aggregation of qualitative studies.

BACKGROUND: An increasing number of people living with HIV (PLWH) have had chronic noncommunicable diseases (NCDs) over the last 5 years. However, robust evidence regarding the perception and challenges of having NCDs among PLWH is limited. Therefore, this study aimed to synthesize qualitative evidence regarding the experiences of PLWH with NCDs. METHODS: We used a meta-aggregation approach to synthesize qualitative studies. Peer-reviewed and gray literature published in English and Chinese from 1996 to November 2020 was searched using electronic databases. Two reviewers independently appraised the methodological quality and extracted data from the included studies. The Joanna Briggs Institute (JBI) meta-aggregation approach was used to synthesize the findings. RESULTS: In total, 10,594 studies were identified in the initial database search. Fourteen eligible studies were included in the meta-synthesis. Among these studies, nine synthesized findings regarding the following topics were identified: fragmented healthcare systems, care continuity, manifestations of multiple conditions, financial hardship, stigma and discrimination, polypharmacy burden and adherence, reciprocal relationships between HIV and NCDs, and coping strategies. CONCLUSIONS: In recent years, attempts have been made to institutionalize NCD preventive and control services in HIV long-term care. However, considering the growing problem of HIV and NCD comorbidity globally, integrated primary health care systems are needed to address the problems of PLWH with NCDs. Healthcare professionals should help PLWH develop strategies to better monitor their polypharmacy burden and adherence, stigma and discrimination, financial hardship, and manifestations of multiple conditions to achieve high levels of care continuity.

A polysaccharide from Dictyophora indusiata inhibits the immunosuppressive function of cancer-associated fibroblasts.

Reversing the function of cancer-associated fibroblasts (CAFs) may improve the efficacy of cancer therapy. Here, we isolated a novel polysaccharide from Dictyophora indusiata (ZSP4) and examined its effects on the function of prostate CAFs. The supernatant of prostate CAFs can stimulate the proliferation of immune cells and inhibit the growth of CD4+/CD8+ T cells. However, after ZSP4 stimulation, the functions of prostate CAFs were inhibited. The mechanism experiment shows that ZSP4 can stimulate prostate CAFs by down-regulating the expression of α-smooth muscle actin. Polysaccharides extracted from Dictyophora indusiata stimulate the proliferation of immune cells and reverse the immune-suppressive functions of prostate CAFs, shedding new light on the development of novel anticancer strategies. The endocrine therapy used to treat prostate cancer aims to eliminate androgenic activity from prostatic tissue; these therapies are painful and of poor therapeutic effect. In this study, we found that polysaccharides extracted from Dictyophora indusiata may affect the micro-environment of tumours and inhibit the growth of the tumours. Our results suggest that polysaccharides may modulate negative immune regulation and enhance antitumour immunity, which is important for clinical therapy.

Psychological profiles among people with HIV: A latent profile analysis and examination of the relationship with interpersonal personality.

People living with HIV (PWH) often experience an increased vulnerability to psychiatric disorders as a result of social stigma and discrimination. This study utilized latent profile analysis on a sample of 3040 Chinese PWH to identify distinct psychological profiles. Furthermore, the study investigated the relationships between these profiles with interpersonal personalities, demographic characteristics, social variables and disease-related variables using a three-step regression (R3STEP). The findings from the latent profile analysis revealed that the psychological symptoms of PWH can be categorized into three distinct classes. Multinomial logistic regression analysis indicated that interpersonal personalities, region, sex, age, religious beliefs, marital status, occupation, monthly income, time of HIV infection diagnosis and transmission route were significant factors associated with the psychological profiles of PWH. These findings provide valuable insights for the development of individualized management strategies for PWH and contribute to a deeper understanding of the mechanisms underlying psychological symptoms of PWH.

Psychometric and Circumplex Properties Evaluation of the International Personality Item Pool-Interpersonal Circumplex (IPIP-IPC) in Chinese People Living with HIV (PLWH).

Background and Purpose: With the improved life expectancy of people living with HIV (PLWH) due to widespread use of antiretroviral therapy (ART), there is a greater emphasis on enhancing long-term well-being and overall quality of life for PLWH. Understanding interpersonal personalities of PLWH can gain further insight into how to improve the overall quality of life in this population. The International Personality Item Pool-Interpersonal Circumplex (IPIP-IPC) scale has been developed to assess interpersonal personalities of individuals, and this scale has been translated into Chinese. However, the Chinese version of IPIP-IPC has not been tested among PLWH in China. In this study, we aimed to test the psychometric properties and circumplex structure of this scale. Methods: This study was based on cross-sectional, multi-center, large sample data. We employed the Chinese version of IPIP-IPC scale on 3040 PLWH from April 2022 to April 2023 in China to test its psychometric as well as circumplex properties. The structural summary method (SSM) was employed to analyze the circumplex structure of the scale. Results: The total scale exhibited a Cronbach's alpha of 0.85 and McDonald's omega of 0.91. Out of the 288 possible relationships, 275 relationships satisfy the circular properties hypothesis. The scale demonstrates good reliability and validity, meeting the requirements of psychometrics. Conclusion: Our findings demonstrate that the Chinese version of the IPIP-IPC scale is a reliable tool for evaluating interpersonal personalities in this population. These results highlight the validity and applicability of the IPIP-IPC scale specifically in the Chinese context, providing valuable insights into the intricacies of interpersonal traits among PLWH.

Psychometric properties of stigma and discrimination measurement tools for persons living with HIV: a systematic review using the COSMIN methodology.

BACKGROUND: The development of antiretroviral therapy broadly extends the life expectancy of persons living with HIV (PLHIV). However, stigma and discrimination are still great threat to these individuals and the world's public health care system. Accurate and reproducible measures are prerequisites for robust results. Therefore, it is essential to choose an acceptable measure with satisfactory psychometric properties to assess stigma and discrimination. There has been no systematic review of different stigma and discrimination tools in the field of HIV care. Researchers and clinical practitioners do not have a solid reference for selecting stigma and discrimination measurement tools. METHODS: We systematically searched English and Chinese databases, including PubMed, EMBASE, CINAHL, Web of Science, PsycINFO, ProQuest Dissertations and Theses, The Cochrane Library, CNKI,, and Wanfang, to obtain literature about stigma and discrimination measurement tools that have been developed and applied in the field of HIV. The search period was from 1st January, 1996 to 22nd November 2021. The COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) guideline (2018 version) was applied to assess the risk of bias for each involved study and summarize the psychometric properties of each tool. The modified version of the Grading of Recommendations Assessment, Development, and, Evaluation (GRADE) method was used to grade the evidence and develop recommendations. RESULTS: We included 45 studies and 19 PROMs for HIV/AIDS-related stigma and discrimination among PLHIV. All studies had sufficient methodological quality in content validity, structural validity, internal consistency, and the hypothesis testing of structural validity. Limited evidence was found for cross-cultural validity, stability, and criterion validity. No relevant evidence was found concerning measurement error and responsiveness. The Internalized AIDS-related Stigma Scale (IARSS), Internalized HIV Stigma Scale (IHSS), and Wright's HIV stigma scale (WHSS) are recommended for use. CONCLUSIONS: This study recommends three PROMs for different stigma and discrimination scenarios, including IARSS for its good quality and convenience, IHSS for its broader range of items, higher sensitivity, and greater precision, and WHSS for its comprehensive and quick screening. Researchers should also consider the relevance and feasibility of the measurements before putting them into practice. SYSTEMATIC REVIEW REGISTRATION: PROSPERO CRD42022308579.

Exploring the experiences of peer support participation for HIV peer volunteers: A meta-synthesis of qualitative research.

BACKGROUND: Gaining insights and feedback from HIV peer volunteers about their peer support practice is crucial for optimizing and enhancing the effectiveness and sustainability of peer support for people with HIV. There is a dearth of systematic reviews that explore the experiences of HIV peer volunteers about their peer support experience. This study aims to consolidate qualitative research on the experiences of peer support participation for HIV peer volunteers, to provide inspiration and reference for HIV peer support practice. METHODS: A meta-aggregation approach was employed to synthesize qualitative studies. Electronic databases were searched for peer-reviewed and gray literature published in English and Chinese between 1996 and September 2022. Two independent reviewers assessed the methodological quality and extracted data from the included studies. The meta-aggregation approach developed by the Joanna Briggs Institute (JBI) was utilized to synthesize the findings. RESULTS: A total of 2610 studies were initially identified through the database search, and twenty-two eligible studies were included in the meta-synthesis. Among the included studies, five presented synthesized findings on the following topics: firstly, taking people with HIV as HIV peer volunteers shows specific motivations and advantages when engaging in peer support practice. Secondly, HIV peer volunteers reinforce the connections between people with HIV and medical institutions, ensuring continuity of care and compensating for the limited availability of medical resources. Thirdly, HIV peer volunteers are capable of providing people with HIV with a higher level of support. Additionally, participating in peer support practice can also yield personal benefits for HIV peer volunteers. Finally, HIV peer support programs face both opportunities and challenges. CONCLUSION: It is necessary to take more flexible and effective approaches to address resource allocation and social support for people with HIV. Peer support presents a mutually beneficial option that holds significant implications for public health systems, clinical healthcare providers, people with HIV, and HIV peer volunteers. It is imperative to develop effective models for HIV peer support practice. Collaborative efforts between relevant departments and personnel, alongside HIV peer volunteers, should be undertaken to formulate support strategies. Additionally, efforts should be made to identify and guide people with HIV into the healthcare system, facilitating comprehensive treatment and care continuity. These measures aim to further reduce HIV transmission, improve the quality of life for people with HIV, and advance the "normalization" of HIV.

The development and evaluation of a social media-based HIV knowledge dissemination platform in China.

Objective: This study aimed to introduce the development of a social media-based HIV knowledge dissemination platform and evaluate its dissemination effects, users' feedback, and preferences. Methods: A social media-based HIV knowledge dissemination platform ("Lihui Space") was developed as a WeChat Official Account (WOA) to disseminate HIV-related information and knowledge to the public and answer subscribers' questions. A cross-sectional study was conducted on 784 platform subscribers between July 2021 and September 2021 to evaluate users' experiences with and preferences for the platform. This platform included three content levels about HIV-related information and knowledge: individual level (health self-management), community level (social function), and society level (news and policy), and dissemination information through texts, pictures, videos, and websites. A descriptive analysis was conducted to estimate the dissemination effects of the platform and evaluation scores. Results: As of September 16, 2021, this platform's WeChat Communication Index (WCI) score was 923.60, the total number of users was 100,008, and the total views in one month was more than 724,000. Participants reported a high level of satisfaction with this platform in terms of overall evaluation (23.36 ± 3.06), readability (18.46 ± 2.63), function evaluation (13.93 ± 1.92), design and structure (22.96 ± 3.36), and interactivity (12.56 ± 2.69). Conclusion: This social media-based platform is currently available in the WeChat application. It is a promising tool for HIV knowledge dissemination and addressing disparities in accessing health care resources.

Social isolation, loneliness and accelerated tooth loss among Chinese older adults: A longitudinal study.

OBJECTIVE: Social isolation and loneliness have been linked to numerous determinants of health and well-being. However, the effects of social isolation and loneliness on oral health remain unclear. The purpose of this study was to examine the effects of social isolation and loneliness on the number of remaining teeth and the rate of tooth loss over time among Chinese older adults. METHODS: We used three waves of data (2011/2012, 2014 and 2018) from the Chinese Longitudinal Healthy Longevity Survey with 4268 older adults aged 65 and older who were interviewed in at least two waves. The number of remaining teeth was first evaluated at baseline and then subsequently at follow-up visits. Mixed-effects Poisson regression was used to examine the associations between social isolation, loneliness, and both the number of remaining teeth and the rate of tooth loss. RESULTS: Social isolation was associated with fewer remaining teeth (ß = -.06, 95% CI = -0.13 to 0.00, p < .05) and accelerated tooth loss (ß = -.02, 95% CI = -0.02 to -0.01, p < .01) after adjusting for sociodemographic covariates, lifestyle and oral hygiene behaviours, physical and cognitive health, and loneliness. Loneliness was neither associated with the number of remaining teeth (ß = .15, 95% CI = -0.01 to 0.30, p = .06) nor with the rate of tooth loss (ß = -.01, 95% CI = -0.02 to 0.00, p = .16) after adjusting for all other factors. CONCLUSIONS: This study provides strong evidence that social isolation was associated with fewer remaining teeth and accelerated tooth loss among Chinese older adults. These findings expand our knowledge about the impact of social disconnection on tooth loss. More future studies are needed to further examine the associations between social connections and oral conditions using longitudinal cohort studies and intervention studies.
