Seipin Deficiency Leads to Energy Dyshomeostasis via Inducing Hypothalamic Neuroinflammation and Aberrant Expression of Neuropeptides.

Seipin is a key regulator of lipid metabolism, the deficiency of which leads to severe lipodystrophy. Hypothalamus is the pivotal center of brain that modulates appetite and energy homeostasis, where Seipin is abundantly expressed. Whether and how Seipin deficiency leads to systemic metabolic disorders via hypothalamus-involved energy metabolism dysregulation remains to be elucidated. In the present study, we demonstrated that Seipin-deficiency induced hypothalamic inflammation, reduction of anorexigenic pro-opiomelanocortin (POMC), and elevation of orexigenic agonist-related peptide (AgRP). Importantly, administration of rosiglitazone, a thiazolidinedione antidiabetic agent, rescued POMC and AgRP expression, suppressed hypothalamic inflammation, and restored energy homeostasis in Seipin knockout mice. Our findings offer crucial insights into the mechanism of Seipin deficiency-associated energy imbalance and indicates that rosiglitazone could serve as potential intervening agent towards metabolic disorders linked to Seipin.

The experiences of nursing students participating in a student death doula service-learning program in palliative care settings: A qualitative study.

Nursing students desire more training and experience in palliative care due to a need for more skills and knowledge. This descriptive qualitative study explored nursing students' experiences in participating in a student death doula service-learning program in palliative care settings. Fourteen final-year undergraduate nursing students participated in semi-structured focus group discussions via Zoom. Four focus group discussions were conducted. Six themes with 19 subthemes were developed: (1) initial feelings of fear and uncertainty, (2) death doula training and orientation, (3) palliative wards being a happier place than expected, (4) experience of watching their patients deteriorate over time, (5) benefits of participating in service-learning in palliative care settings, and (6) improving the service-learning experience. The program was well received by the nursing students, who recommended incorporating it into the nursing curriculum to enhance palliative nursing education. Additional refinements were proposed to better support nursing students during service-learning.

Targeting autophagy with natural products as a potential therapeutic approach for diabetic microangiopathy.

As the quality of life improves, the incidence of diabetes mellitus and its microvascular complications (DMC) continues to increase, posing a threat to people's health and wellbeing. Given the limitations of existing treatment, there is an urgent need for novel approaches to prevent and treat DMC. Autophagy, a pivotal mechanism governing metabolic regulation in organisms, facilitates the removal of dysfunctional proteins and organelles, thereby sustaining cellular homeostasis and energy generation. Anomalous states in pancreatic ß-cells, podocytes, Müller cells, cardiomyocytes, and Schwann cells in DMC are closely linked to autophagic dysregulation. Natural products have the property of being multi-targeted and can affect autophagy and hence DMC progression in terms of nutrient perception, oxidative stress, endoplasmic reticulum stress, inflammation, and apoptosis. This review consolidates recent advancements in understanding DMC pathogenesis via autophagy and proposes novel perspectives on treating DMC by either stimulating or inhibiting autophagy using natural products.

Causal association of obesity with epigenetic aging and telomere length: a bidirectional mendelian randomization study.

BACKGROUND: In observational studies, there exists an association between obesity and epigenetic age as well as telomere length. However, varying and partially conflicting outcomes have notably arisen from distinct studies on this topic. In the present study, two-way Mendelian randomization was used to identify potential causal associations between obesity and epigenetic age and telomeres. METHODS: A genome-wide association study was conducted using data from individuals of European ancestry to investigate bidirectional Mendelian randomization (MR) regarding the causal relationships between obesity, as indicated by three obesity indicators (body mass index or BMI, waist circumference adjusted for BMI or WCadjBMI, and waist-to-hip ratio adjusted for BMI or WHRadjBMI), and four epigenetic age measures (HannumAge, HorvathAge, GrimAge, PhenoAge), as well as telomere length. To assess these causal associations, various statistical methods were employed, including Inverse Variance Weighted (IVW), Weighted Median, MR Egger, Weighted Mode, and Simple Mode. To address the issue of multiple testing, we applied the Bonferroni correction. These methods were used to determine whether there is a causal link between obesity and epigenetic age, as well as telomere length, and to explore potential bidirectional relationships. Forest plots and scatter plots were generated to show causal associations between exposures and outcomes. For a comprehensive visualization of the results, leave-one-out sensitivity analysis plots, individual SNP-based forest plots for MR analysis, and funnel plots were included in the presentation of the results. RESULTS: A strong causal association was identified between obesity and accelerated HannumAge, GrimAge, PhenoAge and telomere length shrinkage. The causal relationship between WCadjBMI and PhenoAge acceleration (OR: 2.099, 95%CI: 1.248-3.531, p = 0.005) was the strongest among them. However, only the p-values for the causal associations of obesity with GrimAge, PhenoAge, and telomere length met the criteria after correction using the Bonferroni multiple test. In the reverse MR analysis, there were statistically significant causal associations between HorvathAge, PhenoAge and GrimAge and BMI, but these associations exhibited lower effect sizes, as indicated by their Odds Ratios (ORs). Notably, sensitivity analysis revealed the robustness of the study results. CONCLUSIONS: The present findings reveal a causal relationship between obesity and the acceleration of epigenetic aging as well as the reduction of telomere length, offering valuable insights for further scientific investigations aimed at developing strategies to mitigate the aging process in humans.

Development of Artificial Intelligence-Teaching Assistant System for Undergraduate Nursing Students: A Field-Testing Study.

Keeping students engaged and motivated during online or class discussion may be challenging. Artificial intelligence has potential to facilitate active learning by enhancing student engagement, motivation, and learning outcomes. The purpose of this study was to develop, test usability of, and explore undergraduate nursing students' perceptions toward the Artificial Intelligence-Teaching Assistant System. The system was developed based on three main components: machine tutor intelligence, a graphical user interface, and a communication connector. They were included in the system to support contextual machine tutoring. A field-testing study design, a mixed-method approach, was utilized with questionnaires and focus group interview. Twenty-one undergraduate nursing students participated in this study, and they interacted with the system for 2 hours following the required activity checklist. The students completed the validated usability questionnaires and then participated in the focus group interview. Descriptive statistics were used to analyze quantitative data, and thematic analysis was used to analyze qualitative data from the focus group interviews. The results showed that the Artificial Intelligence-Teaching Assistant System was user-friendly. Four main themes emerged, namely, functionality, feasibility, artificial unintelligence, and suggested learning modality. However, Artificial Intelligence-Teaching Assistant System functions, user interface, and content can be improved before full implementation.

Associations between dyadic communication and dyadic coping of patients with cervical cancer and their spouses: a study utilizing the actor-partner interdependence model.

There is a growing focus on exploring dyadic interactions and outcomes between couples undergoing cervical cancer (CC). The purpose of this cross-sectional study was to figure out how dyadic communication influences both CC patients' and spouses' coping abilities. A sample of 286 CC dyads completed questionnaires assessing dyadic communication and dyadic coping. The actor-partner interdependence model was used to analyze the interaction effect between the dyads. Dyadic communication among cervical cancer (CC) patients has a predictive effect on their own negative dyadic coping (ß = - 0.141, P = 0.034) and on their spouses' delegated dyadic coping (ß = 0.133, P = 0.044). In contrast, dyadic communication among CC spouses is negatively associated with their own supportive dyadic coping (ß = - 0.237, P < 0.001), delegated dyadic coping (ß = - 0.156, P = 0.018), common dyadic coping (ß = - 0.148, P = 0.026) and also with CC patients' supportive dyadic coping (ß = - 0.153, P = 0.022). Dyadic communication between CC patients and their spouses affect their own and each other's dyadic coping. Exploring interventions focused on the CC couples' communication strategies to enhance their positive dyadic coping should be considered.

Nursing students' perspectives and learning experiences of participating in a palliative and end-of-life care simulation programme: A qualitative study.

BACKGROUND: Simulation-based learning has become an integral part of the nursing curriculum, allowing students to acquire clinical knowledge and relevant skills and apply them to real-life clinical encounters. However, little is known about the best practices in palliative and end-of-life care simulations. OBJECTIVE: To explore the perspectives and learning experiences of undergraduate nursing students participating in a newly developed advanced practice nurse-led palliative and end-of-life care simulation program. DESIGN: A descriptive qualitative study based on focus group discussions. SETTINGS: A healthcare simulation centre at a university in Singapore. PARTICIPANTS: A purposive sample of 75 third-year undergraduate nursing students who had attended a palliative and end-of-life care simulation program. METHODS: Eight face-to-face focus group discussions were conducted and audio recorded. Data were analysed using inductive thematic analysis. RESULTS: Four themes encompassing 12 subthemes were derived: (1) Patient, family and caregiver needs during palliative and end-of-life care, (2) Nursing competencies in palliative and end-of-life care, (3) Experience of palliative and end-of-life care simulations and (4) Suggestions for future palliative and end-of-life simulations. The students expressed their support for including advanced practice nurses as facilitators and suggested the use of other simulation modalities such as virtual simulations to enable the participation of all students and provide a wider range of simulated scenarios. CONCLUSIONS: Simulation-based learning plays a crucial role in the palliative care curriculum. Clinical experts should be involved as facilitators to provide essential insights. It is also vital to consider students' prior experiences with death and dying, which may positively or negatively influence their palliative and end-of-life care competencies. RECOMMENDATIONS: Nursing schools should utilise clinical experts and other simulation modalities to improve students' learning experiences, provide more simulation experiences and overcome resource constraints such as limited curriculum time.

Risk of death and readmission among individuals with heart failure and HIV: A systematic review and meta-analysis.

The association between human immunodeficiency virus (HIV) status and readmissions and death outcomes in patients with established heart failure (HF) remains unclear. We conducted a systematic search of PubMed, EMBASE, Cochrane Library, and Web of Science up to March 1st, 2023, for cohort studies of adult patients (≥18 years) diagnosed with HF and recorded HIV status at baseline. Our analysis included 7 studies with 10,328 HF patients living with HIV and 48,757 HF patients without HIV. Compared to HF patients without HIV, those with HIV had a higher risk of all-cause deaths (HR: 1.20, 95% CI: 1.15-1.25). HIV infection was also associated with increased risks of HF-associated readmission (HR: 1.34, 95% CI: 1.03-1.75) and all-cause readmission (HR: 1.27, 95% CI: 1.10-1.46). Our study highlights the independent association between HIV and poor HF outcomes, emphasizing the need for improved management in individuals living with HIV.

[Potential targets for traditional Chinese medicine treatment of chronic inflammation in obesity: macrophage polarization].

Obesity has been identified as a chronic low-grade systemic inflammation and a key risk factor for diseases such as diabetes, hypertension, and malignancies, and has become an urgent global health burden. Adipose tissue macrophages play a significant role in adipose immune homeostasis and inflammatory responses. Under different conditions, they can be polarized into pro-inflammatory M1 phenotype or anti-inflammatory M2 phenotype. In obese individuals, there is abnormal polarization of macrophages in adipose tissue, leading to an imbalance in the M1/M2 phenotype dynamic equilibrium and the development of pathological inflammation. Therefore, restoring the balance of M1/M2 macrophage polarization is an important potential target for the treatment of chronic inflammation in obesity. Studies have shown that traditional Chinese medicine(TCM) can positively modulate macrophage polarization and produce beneficial effects on obesity. Based on existing evidence, this paper systematically reviewed the potential mechanisms of TCM in improving chronic inflammation in obesity from the perspective of macrophage polarization, in order to provide evidence for the clinical diagnosis and treatment of chronic inflammation in obesity with TCM and offer new insights for related research design and the development of new TCM.

Relationships of person-related, problem-related, and environment-related factors to self-care behaviours and the mediating role of self-confidence among patients with heart failure: Cross-sectional analysis of structural equation modelling.

BACKGROUND: Promoting self-care behaviours in heart failure management is an important goal and challenge for healthcare systems worldwide. Using the situation-specific theory of heart failure self-care, this study examined the relationships of person-related, problem-related, and environment-related factors to self-care behaviours and the mediating role of self-care confidence in these relationships. METHOD: We analysed the baseline data from a previous randomised controlled trial study involving 213 patients with heart failure. Structural equation modelling was used to test our hypothesised model that included age, income, education, depression, anxiety, number of comorbidities, social support, self-care confidence, and self-care behaviours. Depression and anxiety were measured by the Hospital Anxiety and Depression Scale. Social support was measured by the Short Form of the Social Support Questionnaire satisfaction subscale. The Self-Care of Heart Failure Index (version 6.2) was used to assess self-care confidence and self-care behaviours (i.e., self-care maintenance and self-care management). RESULT: The final model included age, depression, social support, and self-care confidence as independent variables. Age had a direct relationship with self-care maintenance (ß = 0.235, p < 0.001) but not self-care management (ß = 0.067, p = 0.179); better social support was directly associated with higher levels of self-care confidence (ß = 0.267, p < 0.001); and higher levels of self-care confidence were associated with better self-care maintenance (ß = 0.573, p < 0.001) and self-care management (ß = 0.683, p < 0.001). The result showed an indirect relationship between social support and self-care maintenance through the mediator of self-care confidence (ß = 0.153, p < 0.001), as well as an indirect relationship between social support and self-care management through self-care confidence (ß = 0.182, p < 0.001). CONCLUSION: Satisfactory social support can increase self-care confidence, thereby increasing self-care maintenance and management. The findings of this study also implied that self-care maintenance can increase with increasing age. Future interventions directly targeting assessment and management of self-care confidence, available social support, and the age of patients may help enhance their heart failure self-care behaviours.

Diagnostic and prognostic value of galactose-deficient IgA1 in patients with IgA nephropathy: an updated systematic review with meta-analysis.

Objectives: Galactose-deficient IgA1 (Gd-IgA1) is a critical effector molecule in the pathogenesis of IgA nephropathy (IgAN), a leading renal disease without noninvasive assessment options. This updated systematic review aimed to determine the diagnostic and prognostic value of Gd-IgA1 assessment in biological fluids in patients with IgAN. Methods: PRISMA guidelines were followed in this review. We searched PubMed, Embase, Cochrane Library, China National Knowledge Infrastructure, China Biology Medicine disc, VIP Information/China Science and Technology Journal Database, and WANFANG for studies published between database inception and January 31, 2023. Eligible studies that evaluated aberrant IgA1 glycosylation in IgAN patients relative to controls were identified, and random effects meta-analyses were used to compare Gd-IgA1 levels in different groups. The quality of the evidence was assessed using the Newcastle-Ottawa Scale. This study was registered on PROSPERO (CRD42022375246). Findings: Of the 2727 records identified, 50 were eligible and had available data. The mean Newcastle-Ottawa Scale score was 7.1 (range, 6-8). Data synthesis suggested that IgAN patients had higher levels of blood and/or urine Gd-IgA1 compared with healthy controls (standard mean difference [SMD]=1.43, 95% confidence interval [CI]=1.19-1.68, P<0.00001), IgA vasculitis patients (SMD=0.58, 95% CI=0.22-0.94, P=0.002), and other kidney disease patients (SMD=1.06, 95% CI=0.79-1.33, P<0.00001). Moreover, patients with IgAN had similar levels of serum Gd-IgA1 compared to first-degree relatives (SMD=0.38, 95% CI= -0.04-0.81, P=0.08) and IgA vasculitis with nephritis patients (SMD=0.12, 95% CI= -0.04-0.29, P=0.14). In addition, ten studies demonstrated significant differences in serum Gd-IgA1 levels in patients with mild and severe IgAN (SMD= -0.37, 95% CI= -0.64--0.09, P=0.009). Conclusions: High serum and urine Gd-IgA1 levels suggest a diagnosis of IgAN and a poor prognosis for patients with this immunological disorder. Future studies should use more reliable and reproducible methods to determine Gd-IgA1 levels.

Predicting the dyadic coping through self-esteem among infertile couples undergoing in vitro fertilization and embryo transfer: An actor-partner interdependence model.

Background: The population of infertile couples receiving in vitro fertilization and embryo transfer in China is increasing gradually. The association of self-esteem and dyadic coping of infertile couples undergoing in vitro fertilization and embryo transfer has not been reported. This investigation aimed to examine the predictive effect of self-esteem of infertile couples undergoing in vitro fertilization and embryo transfer on coping strategies at the dyadic level. Methods: A cross-sectional study involving 283 infertile couples was conducted at the Reproductive Center of Northwest Women and Children's Hospital in China. Participants were asked to complete two self-administered questionnaires, to assess self-esteem (Rosenberg Self-Esteem Scale) and dyadic coping (Dyadic Coping Inventory). Paired t-test and Pearson correlation were used to analyze the difference and correlation of variables between wife and husband. The actor-partner interdependence model was used to test the predictive effect of each individual's self-esteem on their own and their partners' dyadic coping. Results: Infertile couples' self-esteem and dyadic coping are in the medium range. The self-esteem of wives and husbands can fully predict their own dyadic coping. Meanwhile, the husband's self-esteem can predict the wife's stress communication (ß = 0.135, p = 0.025), support dyadic coping (ß = 0.142, p = 0.019), and negative dyadic coping (ß = 0.133, p = 0.024), and the wife's perceived partners' supportive dyadic coping (ß = 0.147, p = 0.014) and negative dyadic coping (ß = 0.144, p = 0.016). Similarly, the wife's self-esteem can predict the husband's supportive dyadic coping (ß = 0.195, p < 0.001), and the husband's perceived partners' stress communication (ß = 0.184, p = 0.003) and supportive dyadic coping (ß = 0.180, p = 0.002). Conclusion: The actor-partner analyses revealed insight into how infertile couples undergoing in vitro fertilization and embryo transfer interact and highlighted the importance of self-esteem in dyadic coping styles. Future psychological interventions can enhance self-esteem as an effective way to improve dyadic coping of infertile couples.

The quality of verbal feedback given by nursing near-peer tutors: A qualitative study.

BACKGROUND: Students' acceptance of peer feedback (PF) in health professions education has been mixed because of doubts about its quality and accuracy. Providing peer tutor (PT) training in giving effective feedback may increase the quality of PF. OBJECTIVES: To analyse the (1) quality and (2) accuracy of near-PF provided to first-year nursing students after simulated practice and (3) evaluate the discrepancies between what faculty, PTs and clinical staff teach about certain nursing skills by analysing PT-student feedback discussions. DESIGN: Qualitative study using content analysis. SETTINGS: This study was conducted in a simulation centre in a Singapore university during first-year undergraduate nursing students' laboratory lessons. PARTICIPANTS: Near-PT (second- to fourth-year undergraduate nursing students). METHODS: Near-PTs received virtual training on providing structured feedback. They provided in-person PF to first-year nursing students after simulated practice of a technical nursing skill. PF was audio recorded. Quality was determined by PTs' adherence to the proposed PF structure and the Debriefing Assessment for Simulation in Healthcare-Rater Version Short Form (DASH-RV-Short) scores. Directed content analyses were also conducted to qualitatively evaluate PF quality based on DASH-RV-Short, PF accuracy and discrepancies in content taught for each nursing skill. RESULTS: Most PTs evaluated the skill chronologically or focused on the mistakes made instead of following the PF structure. DASH-RV-Short scores were 'good' for most elements because PTs gave specific suggestions and justified them, ensured students' psychological safety, and used effective verbal communication. PF was mostly accurate, but expectations relating to each nursing skill differed among the PTs, faculty and clinical staff. CONCLUSIONS: With training, senior nursing students can provide specific and detailed feedback to their juniors, which may fill the gap for timely and specific feedback in health professions education. Future PT training programmes should clarify common variations and mistakes in skills performance to ensure PTs and faculty tutors agree on what students should learn.

[Network Meta-analysis of Qi-supplementing and Yin-nourishing Chinese patent medicines in treatment of early diabetic nephropathy].

This study aimed to evaluate the efficacy of Qi-supplementing and Yin-nourishing Chinese patent medicine in the treatment of early diabetic nephropathy(DN) by network Meta-analysis to explore the Chinese patent medicine with optimal efficacy and provide references for preventing renal deterioration and delaying the progression of early DN. Eight databases, including CNKI, Wanfang, VIP, SinoMed, PubMed, EMbase, Cochrane Library, and Web of Science, were searched for clinical randomized controlled trial(RCT) of Qi-supplementing and Yin-nourishing Chinese patent medicines in the treatment of early DN. After the literature mee-ting the inclusion criteria was screened, the quality of the literature was evaluated using the Cochrane risk-of-bias tool, and network Meta-analysis was performed using the BUGSnet package in R 4.2.1. Seventy-two research articles with a sample size of 6 344 cases were included, involving eight Chinese patent medicines and seven outcome indicators. The results of the network Meta-analysis showed that(1)in terms of improving urinary albumin excretion rate(UAER), Chinese patent medicines combined with conventional treatment were superior to conventional treatment, and Qiyao Xiaoke Capsules + conventional treatment was optimal.(2)In terms of reducing serum crea-tinine(Scr), Bailing Capsules + conventional treatment had superior efficacy.(3)In terms of reducing 24-hour urine total protein(24hUTP), Shenyan Kangfu Tablets + conventional treatment and Jinshuibao Capsules + conventional treatment had equivalent efficacy, and Shenyan Kangfu Tablets + conventional treatment was superior.(4)In terms of improving fasting blood glucose(FBG), Shenyan Kangfu Tablets + conventional treatment had superior efficacy.(5)In terms of improving total cholesterol(TC), Qiyao Xiaoke Capsules +conventional treatment had superior efficacy.(6)In terms of reducing triglyceride(TG), Bailing Capsules + conventional treatment had superior efficacy.(7)In terms of safety, the occurrence of adverse reactions was reported in seven interventions, but due to the large clinical heterogeneity, the quantitative analysis could not be performed. Overall, Qi-supplementing and Yin-nourishing Chinese patent medicines combined with conventional treatment were superior to conventional treatment alone in the treatment of early DN. The results showed that Qi-supplementing and Yin-nourishing Chinese patent medicines combined with conventional treatment had good clinical efficacy, and they could significantly reduce renal function indicators such as UAER, Scr, and 24hUTP, and reduce blood sugar and blood lipid, which can provide evidence-based support for the treatment of early DN. However, due to the differences in the quantity and quality of the included research articles, large-sample, multi-center, high-quality studies are still needed for further verification.

Aloe-emodin inhibits African swine fever virus replication by promoting apoptosis via regulating NF-κB signaling pathway.

African swine fever (ASF) is an acute infectious haemorrhagic fever of pigs caused by African swine fever virus (ASFV). Aloe-emodin (Ae) is an active ingredient of Chinese herbs with antiviral, anticancer, and anti-inflammatory effects. We investigated the antiviral activity and mechanism of action of Ae against ASFV using Real-time quantitative PCR (qPCR), western blotting, and indirect immunofluorescence assays. Ae significantly inhibited ASFV replication. Furthermore, transcriptomic analysis revealed that ASFV infection activated the NF-κB signaling pathway in the early stage and the apoptosis pathway in the late stage. Ae significantly downregulated the expression levels of MyD88, phosphor-NF-κB p65, and pIκB proteins as well as the mRNA levels of IL-1ß and IL-8 in porcine alveolar macrophages (PAMs) infected with ASFV, thereby inhibiting the activation of the NF-κB signaling pathway induced by ASFV. Flow cytometry and western blot analysis revealed that Ae significantly increased the percentage of ASFV-induced apoptotic cells. Additionally, Ae promoted apoptosis by upregulating the expression levels of cleaved-caspase3 and Bax proteins and downregulating the expression levels of Bcl-2 proteins. This suggests that Ae promotes apoptosis by inhibiting the NF-κB pathway, resulting in inhibition of ASFV replication. These findings have further improved therapeutic reserves for the prevention and treatment of ASF.

Sleep quality, social rhythms, and depression among people living with HIV: a path analysis based on social zeitgeber theory.

Background: People living with HIV frequently report sleep disturbances. The social zeitgeber theory, which proposes that stressful life events can interfere with sleep and even depression by destabilizing daily routines, provides new insights into identifying predictors of sleep disturbances and improving sleep in people living with HIV. Objective: To explain the pathways affecting sleep quality in people living with HIV based on social zeitgeber theory. Methods: A cross-sectional study was conducted to assess sleep quality, social rhythms, depression, social support, and coping styles from December 2020 to February 2021. The hypothetical model was tested and respecified by performing path analysis and a bias-corrected bootstrapping method using IBM AMOS 24 software. The report of this study followed the STROBE checklist. Results: A total of 737 people living with HIV participated in the study. The final model presented a good fit (goodness of fit = 0.999, adjusted goodness of fit index = 0.984, normed fit index = 0.996, comparative fit index = 0.998, Tucker-Lewis index = 0.988, root mean square error of approximation = 0.030, chi-squared/degree of freedom = 1.646), explaining 32.3% of the variance in sleep quality among people living with HIV. Lower social rhythm stability was directly associated with poorer sleep quality, and depression mediated the relationship between social rhythms and sleep quality. Social support and coping styles affected sleep quality through social rhythms and depression. Limitation: The cross-sectional study design precludes making assumptions about causality among factors. Conclusion: This study validates and extends the applicability of the social zeitgeber theory in the HIV context. Social rhythms have direct and indirect effects on sleep. Social rhythms, sleep, and depression is not simply linked in a cascading sequence but is theoretically linked in a complex way. More studies are needed to explore the predictors of social rhythms, and interventions for stabilizing social rhythms have the potential to alleviate sleep disturbances and depression in people living with HIV.

Patient decision support interventions for candidates considering elective surgeries: a systematic review and meta-analysis.

BACKGROUND: The increase in elective surgeries and varied postoperative patient outcomes has boosted the use of patient decision support interventions (PDSIs). However, evidence on the effectiveness of PDSIs are not updated. This systematic review aims to summarize the effects of PDSIs for surgical candidates considering elective surgeries and to identify their moderators with an emphasis on the type of targeted surgery. DESIGN: Systematic review and meta-analysis. METHODS: We searched eight electronic databases for randomized controlled trials evaluating PDSIs among elective surgical candidates. We documented the effects on invasive treatment choice, decision-making-related outcomes, patient-reported outcomes, and healthcare resource use. The Cochrane Risk of Bias Tool version 2 and Grading of Recommendations, Assessment, Development, and Evaluations were adopted to rate the risk of bias of individual trials and certainty of evidence, respectively. STATA 16 software was used to conduct the meta-analysis. RESULTS: Fifty-eight trials comprising 14 981 adults from 11 countries were included. Overall, PDSIs had no effect on invasive treatment choice (risk ratio=0.97; 95% CI: 0.90, 1.04), consultation time (mean difference=0.04 min; 95% CI: -0.17, 0.24), or patient-reported outcomes, but had a beneficial effect on decisional conflict (Hedges' g =-0.29; 95% CI: -0.41, -0.16), disease and treatment knowledge (Hedges' g =0.32; 95% CI: 0.15, 0.49), decision-making preparedness (Hedges' g =0.22; 95% CI: 0.09, 0.34), and decision quality (risk ratio=1.98; 95% CI: 1.15, 3.39). Treatment choice varied with surgery type and self-guided PDSIs had a greater effect on disease and treatment knowledge enhancement than clinician-delivered PDSIs. CONCLUSIONS: This review has demonstrated that PDSIs targeting individuals considering elective surgeries had benefited their decision-making by reducing decisional conflict and increasing disease and treatment knowledge, decision-making preparedness, and decision quality. These findings may be used to guide the development and evaluation of new PDSIs for elective surgical care.

Using peer feedback to enhance nursing students' reflective abilities, clinical competencies, and sense of empowerment: A mixed-methods study.

AIM: To assess the use of a framework to provide structured peer feedback and compare the effects of peer video feedback, peer verbal feedback versus faculty feedback on nursing students and peer tutors' learning outcomes and experiences BACKGROUND: Peer feedback has been utilized widely in health professions education to fill the gap for timely feedback, but some students were concerned with its quality, leading to perceptions that peer feedback may not be useful. DESIGN: Sequential explanatory mixed-methods study METHODS: The study took place from January to February 2022. In phase 1, a quasi-experimental pretest-posttest design was used. First-year nursing students (n = 164) were allocated to peer video feedback, peer verbal feedback or faculty feedback arms. Senior nursing students (n = 69) were recruited to be peer tutors or the control group. The Groningen Reflective Ability Scale was used by first-year students to assess their reflective abilities, while the Simulation-based Assessment Tool was used by peer or faculty tutors to evaluate nursing students' clinical competence of a nursing skill during the simulation. The Debriefing Assessment for Simulation in Healthcare-Student Version was used by students to assess their peer/faculty tutors' feedback quality. Senior students' empowerment levels were measured using the Qualities of an Empowered Nurse scale. In phase 2, six semi-structured focus group discussions with peer tutors (n = 29) were conducted and thematically analyzed. RESULTS: Peer video feedback and peer verbal feedback significantly improved students' reflective abilities but not in the faculty feedback arm. Students' clinical competence in a technical nursing skill significantly improved in all three arms. Improvements were significantly larger in those receiving peer video feedback and peer verbal feedback than faculty feedback, with no significant differences between peer video feedback and peer verbal feedback. Debriefing Assessment for Simulation in Healthcare-Student Version scores were not significantly different among the 3 arms. Empowerment levels of peer tutors significantly improved after providing peer feedback but not those in the control group. Seven themes were generated from the focus group discussions. CONCLUSIONS: Although peer video feedback and peer verbal feedback were similarly effective in improving clinical competencies, peer video feedback was more time-consuming and stressful to students. The use of structured peer feedback improved peer tutors' feedback practices and were comparable to quality of faculty feedback. It also significantly increased their sense of empowerment. Peer feedback was widely supported by peer tutors who agreed that it should supplement faculty teaching.

Circadian rhythms and sleep quality among undergraduate students in China: The mediating role of health-promoting lifestyle behaviours.

BACKGROUND: Poor sleep quality have become one of the most pressing public health problems for undergraduate students. The aim of this cross-sectional study was to investigate the relationship between circadian rhythms and sleep quality and the meditating role of health-promoting lifestyles in the relationship of Chinese undergraduate students. METHODS: A total of 3423 students participated. The online survey consisted of the reduced Morningness-Evening Questionnaire (rMEQ), the Pittsburgh Sleep Quality Index (PSQI) and Health-Promoting Lifestyle Profile-II (HPLP-II). Logistic regression models were employed. RESULTS: The prevalence of poor sleep quality is 43.03 %. The total mean scores of HPLP - II, PSQI, and rMEQ are 96.94 ± 17.26, 5.20 ± 2.70 and 14.83 ± 2.10, respectively. A significant negative correlation exists between the rMEQ and PSQI scores (r = -0.262, p < 0.001), but a positive correlation exists between the rMEQ and HPLP scores (r = 0.232, p < 0.001). The total and sub-domain scores of HPLP are also negatively correlated with the PSQI scores (r = -[0.166, 0.291], p < 0.001). Mediation analysis demonstrates the mediation of HPLP (indirect effect = -0.036, p < 0.001) on the effect of the rMEQ on PSQI scores that accounts for 13.30 % of the total effect. LIMITATIONS: Cross-sectional design and recall bias in data collection. CONCLUSIONS: The effect of circadian rhythm on sleep quality is partially mediated by the health-promoting lifestyle. In addition to maintaining a normal circadian rhythm, helping undergraduate students develop a healthy lifestyle is also an effective measure to improve sleep quality.

Nursing students' experiences with patient death and palliative and end-of-life care: A systematic review and meta-synthesis.

AIM: To synthesise the experiences of nursing students encountering patient death and caring for patients under palliative care or at end-of-life and their families in clinical settings BACKGROUND: Nurses are pivotal in caring for dying patients and families. It has been reported that nursing students feel unprepared in caring for dying patients and handling patient death. Understanding their experiences would better inform how palliative care education can be improved and how students can be better supported in clinical settings. DESIGN: A qualitative systematic review and meta-synthesis METHODS: PubMed, Embase, CINAHL, PsycINFO, ProQuest and Google Scholar were searched for peer-reviewed articles and theses/dissertations published between 1 January 2012-25 Feb 2023. Qualitative studies of any design reporting nursing students' experiences of patient death, caring for patients under palliative care, at end-of-life, or with time-limiting diseases in clinical settings in English were included. Study quality was evaluated using the Critical Appraisal Skills Programme tool. Data were synthesised using Sandelowski and Barroso's 2-step framework through a meta-summary using thematic analysis, which were then integrated into meta-syntheses using an event timeline. RESULTS: The review included 71 studies from 26 countries (n = 1586 nursing students). The meta-summary contained 8 themes and 23 subthemes: (1) Communication experience with patients and families, (2) Satisfaction with care provided to patients and families, (3) Impact of the COVID-19 pandemic on death and dying, (4) Perceptions of death and dying, (5) Impact of death, (6) Nursing education on palliative end-of-life care, (7) Support systems and coping methods, (8) Learning outcomes. The meta-synthesis depicted nursing students' experiences before, during and after encountering dying patients, families and patient death. Suggestions for nursing faculty and clinical staff on how they could equip students with necessary skills and knowledge and support them in clinical settings were also provided. CONCLUSIONS: While caring for dying patients and families was beneficial to nursing students' learning and professional development, they encountered many challenges. Governments, clinical and academic nursing leaders must prioritise the integration of palliative care content into the curricula across nursing schools in face of increasing palliative and end-of-life care needs in patients. Nursing schools should ensure that students are adequately prepared by designing culturally and socioeconomically relevant curricula, integrating theoretical and experiential learning and offering students a thorough understanding of palliative and end-of-life care. Clinical staff and nursing instructors should support students emotionally and guide them in patient care.
