Association of dietary iron intake with diabetic kidney disease among individuals with diabetes.

PURPOSE: The current study investigated the correlation between dietary iron intake and diabetic kidney disease among diabetic adults. METHODS: This cross-sectional study enrolled 8118 participants who suffered from diabetes from the National Health and Nutrition Examination Survey (NHANES) 1999-2018. Dietary iron intake was obtained from 24 h recall interviews, and diabetic kidney disease was defined as eGFR < 60 mL/min per 1.73 m2 or albumin creatinine ratio (ACR) ≥ 30 mg/g. Three weighted logistic regression models were utilized to investigate odd ratio (OR) and 95% CIs for diabetic kidney disease. Stratified analyses were performed by gender, age, BMI, HbA1c, hypertension status, and smoking status, and diabetes types. RESULTS: Among 8118 participants (51.6% male, mean age 61.3 years), 40.7% of participants suffered from diabetic kidney disease. With the adjustment of potential covariates, we found that ≥ 12.59 mg of dietary iron was related to a lower risk of diabetic kidney disease (OR = 0.78, 95% CI: 0.63 to 0.96; OR = 0.79, 95% CI: 0.63 to 0.98). In stratified analyses, higher iron intake was negatively related to diabetic kidney disease, especially among those who were male, < 60 years, those with hypertension, those with HbA1c < 7.0%, and those who were ex-smokers. The result remained robust in sensitivity analyses. CONCLUSION: We found that ≥ 12.59 mg of dietary iron is associated with a lower risk of diabetic kidney disease, especially in those who were male, younger, heavier weight, have better blood sugar control, and those who were ex-smokers.

Efficacy of recombinant human epidermal growth factor in pressure injury healing: evidence from Chinese randomized controlled trials.

OBJECTIVE: To evaluate the efficacy of recombinant human epidermal growth factor (rhEGF) in healing pressure injuries (PIs). METHODS: A meta-analysis was conducted of randomized controlled trials (RCTs) involving rhEGF in the treatment of PIs that were identified in PubMed, Web of Science, the Cochrane Library, and China National Knowledge Infrastructure (CNKI). The population, intervention, comparison, outcomes, study design (PICOS) strategy was applied to determine analysis eligibility. The Cochrane risk of bias tool was used, and statistical analysis, including sensitivity analysis, was performed of 3 outcomes indicators: the primary outcome was total efficacy of rhEGF in treating PIs, and the secondary outcomes were the proportion of complete healing and the time to complete healing. Total efficacy refers to the proportion of cases that have been cured, obviously effective, or effective. Complete healing refers to cases where the wound has healed, scabbed, and the scab has sloughed off. RESULTS: Sixteen RCTs were included, comprising a total of 1,206 patients. Study and control group size varied by outcomes. The total effective healing rate in rhEGF group was 97.18%, which was significantly higher than 83.38% in control group (OR: 5.69, [95% CI: 3.61, 8.97], z=7.49, P < .001). The proportion of complete healing in the rhEGF group was 73.30%, which was higher than 39.52% in control group (OR: 3.88, [95% CI: 3.01, 5.01], z=10.39, P < .001). Furthermore, the healing time using rhEGF was shorter (SMD: -2.14 days, [95% CI: -2.60, -1.67], z=9.07, P < .001). Sensitivity analyses indicated that the results were robust. CONCLUSIONS: The meta-analysis indicated that rhEGF was effective in healing PIs with few negative effects. Further research beyond Chinese populations involving larger studies and studies that distinguish between results found in using rhEGF alone or in combination are recommended.

Mortality of children and adolescents co-infected with tuberculosis and HIV: a systematic review and meta-analysis.

OBJECTIVE: Children and adolescents with HIV infection are well known to face a heightened risk of tuberculosis. However, the exact mortality rates and temporal trends of those with HIV-tuberculosis (TB) co-infection remain unclear. We aimed to identify the overall mortality and temporal trends within this population. METHODS: PubMed, Web of Science, and Embase were employed to search for publications reporting on the mortality rates of children and adolescents with HIV-TB co-infection from inception to March 2, 2024. The outcome is the mortality rate for children and adolescents with HIV-TB co-infection during the follow-up period. In addition, we evaluate the temporal trends of mortality. RESULTS: During the follow-up period, the pooled mortality was 16% [95% confidence interval (CI) 13-20]. Single infection of either HIV or TB exhibit lower mortality rates (6% and 4%, respectively). We observed elevated mortality risks among individuals aged less than 12 months, those with extrapulmonary TB, poor adherence to ART, and severe immunosuppression. In addition, we observed a decreasing trend in mortality before 2008 and an increasing trend after 2008, although the trends were not statistically significant ( P  = 0.08 and 0.2 respectively). CONCLUSIONS: Children and adolescents with HIV-TB co-infection bear a significant burden of mortality. Timely screening, effective treatment, and a comprehensive follow-up system contribute to reducing the mortality burden in this population.

Non-pharmacological interventions for preventing suicide attempts: A systematic review and network meta-analysis.

Suicide attempts can cause serious physical harm or death. It would be crucial to gain a better understanding of the comparative efficacy of non-pharmacological interventions. We aimed to identify which non-pharmacological interventions are more effective in preventing suicide attempts. PubMed, Web of Science, and EMBASE databases were searched systematically from their inception until 3 April 2023. To be eligible for inclusion, randomized controlled trials (RCTs) had to meet the following criteria: Participants were individuals who had suicidal ideation or a history of severe self-harm or attempted suicide. A network meta-analysis was performed using a random effects model to estimate the treatment effect of various non-pharmacological interventions. (PROSPERO registration number: CRD42023411393). We obtained data from 54 studies involving 17,630 participants. Our primary analysis found that Cognitive therapy (CT) (OR=0.19, 95%CI =0.04-0.81), Dialectical Behavior Therapy (DBT) (OR=0.37, 95%CI =0.13-0.97), Cognitive-behavioral therapy (CBT) (OR=0.42, 95%CI =0.17-0.99), and Brief intervention and contact (BIC) (OR=0.65, 95%CI=0.44-0.94) were superior to TAU (within the longest available follow-up time) in preventing suicide attempts, while other intervention methods do not show significant advantages over TAU. Secondary analysis showed that the two intervention measures (CT and BIC) were effective when follow-up time did not exceed 6 months, but there was no effective intervention measure with longer follow-up times. CT, DBT, CBT, and BIC have a better effect in preventing suicide attempts than other non-pharmacological interventions. Additional research is necessary to validate which interventions, as well as which combinations of interventions, are the most effective.

Effect of Socioeconomic Disparities on Suicide Risk in Patients With Prostate Cancer During 2005 to 2020: A Population Study.

PURPOSE: To determine whether socioeconomic disparities have an impact on the likelihood of suicide among prostate cancer patients. METHODS: Data were extracted from the Surveillance, Epidemiology, and End Results (SEER) database for patients diagnosed with malignant prostate cancer between 2005 and 2020. The socioeconomic disparities of the patients were evaluated by median household income (MHI) and ethnicity. Ethnicity included Spanish-Hispanic-Latino and non-Spanish-Hispanic-Latino. A Cox proportional risk model was utilized. Using the Kaplan-Meier approach, the cumulative incidence of suicide mortality was measured. RESULTS: A total of 857,418 US population with prostate cancer were included. In the multivariate analysis, individuals with MHI over $75,000 had a lower risk of suicide mortality than those with MHI between $54,999 and $74,999 in all patients (aHRs: 0.693, 95 CI%: 0.603-0.797). Spanish-Hispanic-Latino displayed lower overall suicide mortality in all patients (aHRs: 0.426, 95% CI: 0.323-0.561). In the subgroup analysis of different ages, individuals with MHI over $75,000 had a lower risk of suicide than those with MHI between $54,999 and $74,999 in patients 60 to 79 years (aHRs: 0.668, 95% CI: 0.562-0.794) and individuals with MHI below $54,999 had higher suicide risk than those with MHI between $54,999 and $74,999 in patients 80+ years (aHRs: 1.786, 95% CI: 1.100-2.902). Hispanic-Latino individuals had lower overall suicide mortality in 00 to 59 years (aHRs: 0.420, 95% CI: 0.240-0.734), 60 to 79 years (aHRs: 0.445, 95% CI: 0.319-0.621), 80+ years (aHRs: 0.363, 95% CI: 0.133-0.988). CONCLUSION: Socioeconomic disparities, including MHI and ethnicity, are important factors strongly related to suicide risk in prostate cancer patients. The lower MHI individuals and non-Spanish-Hispanic-Latino individuals were associated with higher suicide risk.

Adverse perinatal pregnancy outcomes in women with schizophrenia: A systematic review and meta-analysis.

INTRODUCTION: Schizophrenia is a severe mental illness that affects a significant proportion of the global population, particularly those of childbearing age. Several studies have attempted to find an association between schizophrenia and obstetric complications, with varying results. OBJECTIVE: The primary objective of this systematic review and meta-analyses was to summarize the relationship between maternal schizophrenia and perinatal pregnancy outcomes. DATA SOURCES: PubMed, Web of Science and Ovid EMBASE were searched from January 2001 to September 2022 using keywords related to pregnancy, women, schizophrenia. STUDY SELECTION: A total of 23 independent studies across 21,253 individuals with schizophrenia were identified and included in the analysis. DATA EXTRACTION: The following data were extracted: author, year of publication, country/continent of data collection, study design, demographic characteristics, diagnoses criteria, related complications. Data were analyzed using random-effects pairwise meta-analysis and were reported as prevalence and odd ratios (OR). Statistical heterogeneity was quantified with the I2 statistic. RESULTS: The prevalence of adverse perinatal pregnancy outcomes was represented in descending order: cesarean section (26.0 %); labor induction (24.0 %); small for gestational age (10.5 %); gestational diabetes mellitus (9.2 %); preterm birth (9.1 %); low birth weight (7.8 %); preterm rupture of membranes (6.1 %); 1-Minute Apgar Score < 7 (5.6 %); large for gestational age (5.5 %); birth defect (5.4 %); antepartum hemorrhage (4.4 %);preeclampsia/eclampsia (4.8 %); postpartum hemorrhage (3.9 %); 5-Minute Apgar Score < 7 (3.6 %); gestational hypertension (3.3 %); placental abruption (1.0 %); placenta previa (0.6 %); thromboembolic disease (0.4 %); neonatal mortality (0.3 %) (P ≤ 0.05). There was a higher risk of adverse outcomes including gestational diabetes mellitus, preeclampsia/eclampsia, placental abruption, thromboembolic disease, preterm birth, birth defect, 1-Minute Apgar score < 7, small for gestational age, low birth weight and neonatal mortality compared with non-schizophrenia population (P ≤ 0.05). CONCLUSIONS: Women with schizophrenia are at higher risk of adverse perinatal pregnancy outcomes. It is imperative that research efforts continue to focus on the reproductive safety of women with schizophrenia during their childbearing years.

The connection between six common air pollution particles and adult brain tumors: a meta-analysis of 26,217,930 individuals.

Environmental air pollutants (black carbon (BC), nitrogen oxides (NOx), particulate matter with diameter < 2.5 µm (PM2.5), nitrogen dioxide (NO2), particulate matter with diameter <10 µm (PM10), and ozone (O3)) are one of the major menaces to mankind's health globally. This analysis reviews the association between exposure to these air pollutants and the chance of developing brain tumors in adults (total brain tumors, malignant brain tumors, and benign brain tumors). Studies published by April 2022 were searched. Raw effect sizes were converted to standardized effect sizes per 10 µg/m3 increase. Random effect models were applied to calculate combined effect size and 95% confidence intervals (CIs) were computed. A total of 8 articles were included for meta-analysis. The pooled effect size (ES) for per 10 µg/m3 BC intake was 1.67 (95% CI: 1.25, 2.22), P = 0.449. For every 10 µg/m3 rise in NO2 concentration, ES was 1.03 (95% CI: 1.01, 1.05), P = 0.319. Meanwhile, there was a boundary association between NOx and adult brain tumors (ES and 95% CI: 1.01; 1.00, 1.01/10 µg/m3; P = 0.716). While there was no conjunction between PM2.5, PM10, O3 (PM2.5: ES and 95% CI: 1.04; 0.99, 1.08/10 µg/m3; P = 0.834; PM10: ES and 95% CI: 1.01; 0.97, 1.04/10 µg/m3; P = 0.627; O3: ES and 95% CI: 0.97; 0.94, 1.00/10 µg/m3; P = 0.253). This research shows testimony of a significant link between air pollutants and brain tumors in adults, especially when exposed to BC, NO2, and NOx. This evidence emphasizes the importance of improving air quality as part of a comprehensive approach to prevent the occurrence and deterioration of brain tumors.

Impact of the National Nursing Development Plan on nursing human resources in China: An interrupted time series analysis for 1978-2021.

BACKGROUND: Shortages of nurses and unequal distribution of nursing staff have been huge challenges for global health services. OBJECTIVES: The aim of our study was to evaluate the impact of the National Nursing Development Plan on nursing human resources in China. METHODS: An interrupted time series design was used in this study. The data for this study were extracted from the National Health Statistics Yearbook from 1978 to 2021. The Ministry of Health issued the National Nursing Development Plan (2005-2010) in July 2005. Subsequently, the strategic plan was issued every 5 years: the National Nursing Development Plan (2011-2015), the National Nursing Development Plan (2016-2020), and the National Nursing Development Plan (2021-2025). This study used five indicators including 1) the number of registered nurses (RNs) in China, 2) the number of RNs per 1000 population in China, 3) the proportion of RNs in health technical personnel in China, 4) the doctor-nurse ratio and 5) the number of nurses working in primary medical institutions to evaluate the changing trend of nursing human resources in China from 1978 to 2021. RESULTS: Interrupted time series analysis showed that after the implementation of the National Nursing Development Plan (2005-2010), the building of nurses in China was gradually strengthening, and the number of RNs in China increased by 0.198 million per year (95%CI 0.174-0.223; P < 0.001); the number of RNs per 1000 population (Coefficient = 0.139; 95%CI 0.123-0.154; P < 0.001); the proportion of RNs in the total number of health professionals in China has increased from 29.6 % to 44.6 % (Coefficient = 0.010; 95%CI 0.009-0.010; P < 0.001); in China, the doctor-nurse ratio increased by 0.024 (95%CI 0.019-0.029; P < 0.001). In 2021, the number of RNs working in primary medical institutions increased by approximately 0.86 million compared with that in 2005, and the proportion of RNs in the country increased by 1.4 %. The development of nurses is especially tilted to the primary level to meet the health and nursing needs of the primary level. CONCLUSIONS: The implementation of the National Nursing Development Plan has greatly expanded the scale of nursing human resources in China and significantly optimized the efficiency of allocation. The implementation of the National Nursing Development Plan (2011-2015) and the National Nursing Development Plan (2016-2020) well continued the strategic plan from 2005 to 2010, further expanded the nursing workforce and further optimized the allocation efficiency. TWEETABLE ABSTRACT: The implementation of the National Nursing Development Plan has greatly expanded the scale of nursing human resources in China and significantly optimized the efficiency of allocation.

Socioeconomic status on survival outcomes in patients with colorectal cancer: a cross-sectional study.

BACKGROUND: Colorectal cancer (CRC) is widely acknowledged as a prevalent malignancy and the second most common cause of cancer-related mortality worldwide. The aim of this study was to examine the independent impact of Median Household Income (MHI) on prognosis and survival outcomes in patients with CRC. METHODS: Data from 17 cancer registries of the United States Surveillance, Epidemiology, and End Results program, with follow-up extended until November 2022 was analyzed. A Cox proportional hazards regression analysis was conducted to evaluate the influence of different levels of MHI on survival outcomes among patients with CRC. A total of 761,697 CRC patient records were retrieved from the SEER database. RESULTS: The Cox regression analysis results indicated that patients with higher MHI exhibited improved overall survival outcomes when compared to those with lower MHI (MMHI: P < 0.001; HMHI: P < 0.001). Regardless of the specific tumor location, gender, stage of CRC, or treatment method, higher MHI is consistently linked to improved survival outcomes. However, this association was not found to be statistically significant among American Indian/Alaska Native (MMHI: P = 0.017; HMHI: P = 0.081), Asian or Pacific Islander (MMHI: P = 0.223; HMHI: P = 0.002) and unmarried or domestic partner patients (MMHI: P = 0.311; HMHI: P = 0.011). CONCLUSION: These results emphasize the importance of considering socioeconomic factors, such as income level, in understanding and addressing disparities in survival outcomes of CRC patients.

Insight into the regulatory mechanism of dynamic chromatin 3D interactions during cardiomyocyte differentiation in human.

Cardiogenesis is an extremely complicated process involved with DNA regulatory elements, and trans factors regulate gene expression pattern spatiotemporally. Enhancers, as the well-known DNA elements, activate target gene expression by transcription factors (TFs) occupied to organize dynamic three-dimensional (3D) interactions, which when affected or interrupted might cause heart defects or diseases. In this study, we integrated transcriptome, 3D genome, and regulatome to reorganize the global 3D genome in cardiomyogenesis, showing a gradually decreased trend of both chromatin interactions and topological associating domains (TADs) during cardiomyocyte differentiation. And almost all of the chromatin interactions occurred within the same or between adjacent TADs involved with enhancers, indicating that dynamical rewiring of enhancer-related chromatin interactions in the continuous expansive TADs is closely correlated to cardiogenesis. Moreover, we found stage-specific interactions activate stage-specific expression to be involved within corresponding biological functions, and the stage-specific combined regulations of enhancers and binding TFs form connected networks to control stage-specific expression and biological processes, which promote cardiomyocyte differentiation. Finally, we identified markers based on regulatory networks, which might drive cardiac development. This study demonstrates the power of enhancer interactome combined with active TFs to reveal insights into transcriptional regulatory networks during cardiomyogenesis.

Incidence, prevalence and risk factors of device-related pressure injuries in adult intensive care unit: A meta-analysis of 10,084 patients from 11 countries.

Device-related pressure injuries (DRPIs) prevail in the intensive care unit (ICU) and have much to do with medical devices and patients' conditions. This meta-analysis aims to systematically assess the incidence, prevalence and risk factors related to DRPIs among adults in ICU. Web of Science, Cochrane Library, MEDLINE, PubMed and CINAHL were searched from inception to March 2023. Observational studies were included, and the Newcastle-Ottawa scale (NOS) was used to assess literature quality. The primary outcomes were the incidence, prevalence and risk factors regarding DRPIs among adults in ICU. The 19 studies conformed to the criteria for inclusion in the review. The estimated pooled incidence of DRPIs was 14.7% (95% CI: 9.7%-19.6%) in 10 studies (4866 participants). The estimated pooled prevalence of DRPIs was 19.0% (95% CI: 13.6%-24.3%) in 9 studies (5218 participants). The most significant risk factor for DRPIs was using mechanical ventilation. The pooled analysis of the four studies showed that DRPIs were more likely to occur in patients who required mechanical ventilation compared with patients who did not use mechanical ventilation (OR: 9.67, 95% CI: 5.03-18.61, p < 0.001) and using vasopressors, age, length of ICU stays, APACHE II score, Braden score, fever, sex, oedema, diabetes and number of medical devices, SOFA score was also related to pressure injuries risk. The incidence and prevalence of DRPIs in adult ICU were high, and the most significant risk factor for DRPIs was using mechanical ventilation. It is imminent to identify patients of increased risk with DRPIs early.

QTc prolongation in patients with schizophrenia taking antipsychotics: Prevalence and risk factors.

BACKGROUND: QTc prolongation is one of the possible complications in patients with schizophrenia taking antipsychotics, which leads to malignant cardiac arrhythmia. No meta-analysis has been reported assessing the prevalence and correlated risk factors for QTc prolongation. METHODS: This meta-analysis aimed to assess the evidence for the prevalence of QTc prolongation and correlated risk factors in patients with schizophrenia taking antipsychotics. Web of Science and PubMed were searched according to preset strategy. The quality of research was assessed by the Newcastle-Ottawa Scale (NOS). RESULTS: In all, 15 studies covering 15,540 patients with schizophrenia taking antipsychotics were included. Meta-analysis showed that the prevalence of QTc prolongation in patients with schizophrenia taking antipsychotics was about 4.0% (95% confidence interval (CI): 3.0%-5.0%, p < 0.001). The prevalence was about 4.0% in Asia (95%CI: 3.0%-6.0%, p < 0.001), about 5.0% in Europe (95%CI: 2.0%-7.0%, p < 0.001), and about 2.0% in America (95%CI: 1.0%-3.0%, p < 0.001). Sensitivity analyses indicated the robustness of the result. Publication bias analysis reported a certain publication bias (t = 3.37, p = 0.012). Meta-regression suggested that female and elderly patients were clinically associated with a higher prevalence of QTc prolongation. According to included studies, smoking, comorbidity of cardiovascular disease, and abnormal levels of high-density lipoprotein/low-density lipoprotein might be related to QTc prolongation in patients with schizophrenia taking antipsychotics. CONCLUSIONS: The prevalence of QTc prolongation in patients with schizophrenia taking antipsychotics was about 4.0%. Female and elderly patients were more likely to experience QTc prolongation. Close electrocardiogram monitoring was suggested in these at-risk populations.

Gender differences in suicide among patients with bipolar disorder: A systematic review and meta-analysis.

OBJECTIVE: To examine gender differences in suicidal ideation, suicide attempts, and suicide deaths in patients with bipolar disorder. METHODS: PubMed, Web of Science, and Embase were systematic searched from inception to March 7, 2023. Two reviewers extract data independently. Demographic data, the number of males and females with bipolar disorder, and the number of individuals with suicidal ideation, suicide attempts, and suicide deaths among participants were extracted. RESULTS: The pooled prevalence of suicidal ideation in males and females was 48.0 % and 44.0 %, respectively, and the overall male-to-female ratios present a statistically insignificant result (OR = 0.95, 95%CI = 0.75-1.21) among patients with bipolar disorder. The pooled prevalence of suicide attempts in males and females was 6.7 % and 9.3 %, respectively, and there was a statistically significant lower prevalence among male patients with bipolar disorder (OR = 0.71, 95%CI = 0.67-0.75). However, the pooled prevalence of suicide deaths in males and females was 0.7 % and 0.3 % respectively, and there was a statistically significant higher prevalence among male patients with bipolar disorder (OR = 1.86, 95%CI = 1.63-2.13). LIMITATIONS: The included studies were from mainly middle- and high-income countries and used inconsistent measurement tools. Thus, there is a potential for bias in our results. CONCLUSIONS: Among patients with bipolar disorder, females were found to have a higher prevalence of suicide attempts, while males have a higher prevalence of suicide deaths. However, there is no significant gender difference in suicidal ideation. Efforts to optimize recognition, treatment, and administration in males and females may reduce gender differences.

CERS6-derived ceramides aggravate kidney fibrosis by inhibiting PINK1-mediated mitophagy in diabetic kidney disease.

During diabetic kidney disease (DKD), ectopic ceramide (CER) accumulation in renal tubular epithelial cells (RTECs) is associated with interstitial fibrosis and albuminuria. As RTECs are primarily responsible for renal energy metabolism, their function is intimately linked to mitochondrial quality control. The role of CER synthesis in the progression of diabetic renal fibrosis has not been thoroughly investigated. In this study, we observed a significant upregulation of ceramide synthase 6 (Cers6) expression in the renal cortex of db/db mice, coinciding with increased production of CER (d18:1/14:0) and CER (d18:1/16:0) by Cer6. Concurrently, the number of damaged mitochondria in RTECs rose. Cers6 deficiency reduced the abnormal accumulation of CER (d18:1/14:0) and CER (d18:1/16:0) in the kidney cortex, restoring the PTEN-induced kinase 1 (PINK1)-mediated mitophagy in RTECs, and resulting in a decrease in damaged mitochondria and attenuation of interstitial fibrosis in DKD. Automated docking analysis suggested that both CER (d18:1/14:0) and CER (d18:1/16:0) could bind to the PINK1 protein. Furthermore, inhibiting PINK1 expression in CERS6 knockdown HK-2 cells diminished the therapeutic effect of CERS6 deficiency on DKD. In summary, CERS6-derived CER (d18:1/14:0) and CER (d18:1/16:0) inhibit PINK1-regulated mitophagy by possibly binding to the PINK1 protein, thereby exacerbating the progression of renal interstitial fibrosis in DKD.NEW & NOTEWORTHY This article addresses the roles of ceramide synthase 6 (CERS6) and CERS6-derived ceramides in renal tubular epithelial cells of diabetic kidney disease (DKD) associated interstitial fibrosis. Results from knockdown of CERS6 adjusted the ceramide pool in kidney cortex and markedly protected from diabetic-induced kidney fibrosis in vivo and in vitro. Mechanically, CERS6-derived ceramides might interact with PINK1 to inhibit PINK1/Parkin-mediated mitophagy and aggravate renal interstitial fibrosis in DKD.

The Relationship Between Loneliness and Internet or Smartphone Addiction Among Adolescents: A Systematic Review and meta-Analysis.

Background: Loneliness is a common public health problem that influences people's physical and mental health. There is a high incidence of loneliness in adolescents. Some research suggested that smartphone or Internet addiction (SA or IA) may be a factor. But the relationship between loneliness and SA or IA is not completely clear among adolescents. We aim to estimate the correlation coefficient r between them. Methods: Databases, consisting of PubMed and Web of Science, were retrieved systematically for studies of the association between adolescents' loneliness and SA or IA. The Newcastle-Ottawa Scale was chosen as an assessment tool in this analysis. We estimated the correlation coefficient r between loneliness and SA or IA and drew a forest plot. Moreover, moderator analyses were also conducted to explore what leads to heterogeneity in our study. Results: 21 studies were finally included in our analysis with 27,843 samples. The pooled correlation coefficient r was 0.252 (95% confidence interval: [0.173, 0.329]; p < 0.001) with low heterogeneity (I2 = 0.000%; Q = 23.616; p < 0.001), indicating a moderate positive association. The funnel plot indicated small publication bias. A one-study removal sensitivity analysis indicated there was no significant difference between these studies. Meta-regression indicated no significant difference between the results and age (Q = 11.94, df = 18, p = 0.8504). Conclusions: Our analysis indicated a moderate positive association between loneliness and SA or IA. The results may attract the attention of some experts who study adolescent psychological problems and behavioral problems and may provide ideas for their research in the future.

Global prevalence of nursing burnout syndrome and temporal trends for the last 10 years: A meta-analysis of 94 studies covering over 30 countries.

AIMS AND OBJECTIVES: To determine the global prevalence of nursing burnout syndrome and time trends for the last 10 years. BACKGROUND: The prevalence of burnout syndrome varied greatly in different regions in the last 10 years, so the average prevalence and time trends of nursing burnout syndrome for the last 10 years were not completely clear. DESIGN: A meta-analysis conducted in the PRISMA guidelines. METHODS: CINAHL, Web of Science, and PubMed were searched for trials on the prevalence of nursing burnout syndrome from 2012 to 2022 systematically. Hoy's quality assessment tool was used to evaluate the risk of bias. The global prevalence of nursing burnout syndrome was estimated, and subgroup analysis was used to explore what caused heterogeneity. Time trends for the last 10 years were evaluated by meta-regression using Stata 11.0. RESULTS: Ninety-four studies reporting the prevalence of nursing burnout were included. The global prevalence of nursing burnout was 30.0% [95% CI: 26.0%-34.0%]. Subgroup analysis indicated that the specialty (p < .001) and the region (p < .001) and the year (p < .001) were sources of the high heterogeneity. Meta-regression indicated that it tended to increase gradually for the last 10 years (t = 3.71, p = .006). The trends increased in Europe (t = 4.23, p = .006), Africa (t = 3.75, p = .006) and obstetrics (t = 3.66, p = .015). However, no statistical significance was found in ICU (t = -.14, p = .893), oncology (t = -0.44, p = .691) and emergency department (t = -0.30, p = .783). CONCLUSIONS: A significant number of nurses were found to have moderate-high levels of burnout syndrome for the last 10 years. The meta-analysis also indicated an increased trend over time. Therefore, more attention to the prevalence of nursing burnout syndrome is urgently required. RELEVANCE TO CLINICAL PRACTICE: High prevalence of nursing burnout may attract more attention from the public. This analysis may serve as an impetus for relevant policy to change nurses' working conditions and reduce the occurrence of burnout.

COVID-19 pandemic increases the occurrence of nursing burnout syndrome: an interrupted time-series analysis of preliminary data from 38 countries.

AIM: To evaluate the trends in nursing burnout rates before and during the coronavirus 2019 restrictions. METHOD: Meta-analysis was used to extract the data on global nursing burnout from 1 Jan. 2010-15 Dec. 2022. An interrupted time-series analysis using segmented ordinary least squares (OLS) regression models was used to explore if the nursing burnout were affected by the epidemic. Newey-West standard error was used to adjust for autocorrelation and heteroskedasticity. RESULTS: Before the epidemic (April 2020), the nursing burnout rate rose with 0.0007497 (95% CI: 0.0000316, 0.0014677, t = 2.07, P = 0.041) per month. The trend of nursing burnout rate has increased by 0.0231042 (95 CI%:0.0086818, 0.0375266, t = 3.18, P = 0.002). The increasing trend of nursing burnout rate after the COVID-19 restrictions is 0.0007497 + 0.0231042 = 0.0238539 per month. CONCLUSION: The study indicated that the Covid-19 restrictions had an impact on nursing burnout, increasing the occurrence of nursing burnout syndrome.

Clinical outcomes of the severe acute respiratory syndrome coronavirus 2 Omicron and Delta variant: systematic review and meta-analysis of 33 studies covering 6 037 144 coronavirus disease 2019-positive patients.

BACKGROUND: Although the SARS-CoV-2 Omicron variant is considered to induce less severe disease, there have been no consistent results on the extent of the decrease in severity. OBJECTIVES: To compare the clinical outcomes of COVID-19-positive patients with Omicron and Delta variant infection. DATA SOURCES: Searches were implemented up to 8 November 2022 in PubMed, Web of Science, BioRvix, and MedRvix. STUDY ELIGIBILITY CRITERIA: Eligible studies were cohort studies reporting the clinical outcomes of COVID-19-positive patients with Omicron and Delta variant infection, including hospitalization, intensive care unit (ICU) admission, receiving invasive mechanical ventilation (IMV), and death. PARTICIPANTS: COVID-19-positive patients with Omicron and Delta variant infection. ASSESSMENT OF RISK OF BIAS: Risk of bias was assessed employing the Newcastle-Ottawa Scale. METHODS OF DATA SYNTHESIS: Random-effect models were employed to pool the ORs and 95% CIs to compare the risk of clinical outcome. I2 was employed to evaluate the heterogeneity between studies. RESULTS: A total of 33 studies with 6 037 144 COVID-19-positive patients were included in this meta-analysis. In the general population of COVID-19-positive patients, compared with Delta, Omicron variant infection resulted in a decreased risk of hospitalization (10.24% vs. 4.14%, OR = 2.91, 95% CI = 2.35-3.60), ICU admission (3.67% vs. 0.48%, OR = 3.64, 95% CI = 2.63-5.04), receiving IMV (3.93% vs. 0.34%, OR = 3.11, 95% CI = 1.76-5.50), and death (2.40% vs. 0.46%, OR = 2.97, 95% CI = 2.17-4.08). In the hospitalized patients with COVID-19, compared with Delta, Omicron variant infection resulted in a decreased risk of ICU admission (20.70% vs. 12.90%, OR = 1.63, 95% CI = 1.32-2.02), receiving IMV (10.90% vs. 5.80%, OR = 1.65, 95% CI = 1.28-2.14), and death (10.72% vs. 7.10%, OR = 1.44, 95% CI = 1.22-1.71). CONCLUSIONS: Compared with Delta, the severity of Omicron variant infection decreased.

Network meta-analysis of mineralocorticoid receptor antagonists for diabetic kidney disease.

Diabetic kidney disease (DKD) is one of the major causes of end-stage renal disease (ESRD). To evaluate the efficacy and safety of different types of mineralocorticoid receptor antagonists (MRAs) in diabetic kidney disease patients, we conducted this network meta-analysis by performing a systematic search in PubMed, MEDLINE, EMBASE, Web of Science, the Cochrane Library, and Clinicaltrials.gov. A total of 12 randomized clinical trials with 15,492 patients applying various types of MRAs covering spironolactone, eplerenone, finerenone, esaxerenone, and apararenone were included. The efficacy outcomes were the ratio of urine albumin creatine ratio (UACR) at posttreatment vs. at baseline, change in posttreatment estimated glomerular filtration (eGFR) vs. at baseline, and change in posttreatment systolic blood pressure (SBP) vs. at baseline. The safety outcome was the number of patients suffering from hyperkalemia. High-dose finerenone (MD -0.31, 95% CI: -0.52, -0.11), esaxerenone (MD -0.54, 95% CI: -0.72, -0.30), and apararenone (MD -0.63, 95% CI: -0.90, -0.35) were associated with a superior reduction in proteinuria in patients with DKD. Regarding the change in eGFR, the results of all drugs were similar, and finerenone may have potential superiority in protecting the kidney. Compared with placebo, none of the treatments was associated with a higher probability of controlling systolic blood pressure during treatment. Moreover, spironolactone, esaxerenone, and 20 mg of finerenone presented a higher risk of hyperkalemia. This Bayesian network meta-analysis was the first to explore the optimal alternative among MRAs in the treatment of DKD and revealed the superiority of 20 mg of finerenone among MRAs in treating DKD.
