Latent tuberculosis infection status among freshmen in boarding middle schools in Longgang District of Shenzhen City / 中国学校卫生

Objective@#To analyze the current status of latent tuberculosis infection (LTBI) among freshmen in boarding middle schools in Longgang District, Shenzhen, so as to provide reference for formulating tuberculosis prevention and control strategies in the next stage.@*Methods@#Data for tuberculosis health examination conducted among primary and secondary school students in Longgang District of Shenzhen in September 2022 to May 2023 were utilized to analyze the latent tuberculosis infection rate, and to explore the differences in latent tuberculosis infection rate among different grades, school nature, school categories and school levels.@*Results@#The latent tuberculosis infection rate among freshmen in boarding secondary schools in Longgang District, Shenzhen in 2022 was 2.45%. The infection rate among full middle school (6.45%) and high school (3.37%) were higher than that in boarding junior high school (0.28%), nine year education school (0) and twelve year education school (1.00%) ( P <0.01). Moreover, the infection rate of high school freshmen (2.68%) was higher than that of bording junior high school (0.33%), and the rate of public schools (2.87%) and municipal schools (3.24%) were higher than those of private schools (1.78%) and distric-level schools (2.13%) respectively, with statistical significance observed for all differences( χ 2=43.58, 25.15, 22.69, P <0.01).@*Conclusions@#The latent tuberculosis infection rate among new boarding secondary students is relatively low in Longgang District of Shenzhen. However, the infection rate is higher in high school, public and municipal school. School should fully guarantee sports participation of students, enhance students awareness of tuberculosis through health knowledge lectures, and reduce the incidence of tuberculosis among students.

Strategies in activating lymphatic system on symptom distress and health-related quality of life in patients with heart failure: secondary analysis of a pilot randomized controlled trial.

Background: Abnormal interstitial fluid accumulation remains the major cause for patients with heart failure (HF) to endure a myriad of distressing symptoms and a decline in their health-related quality of life (HRQoL). The lymphatic system is essential in regulating fluid balance within the interstitial compartment and has recently been recognized as an important target for the prevention and mitigation of congestion. This study aimed to investigate the effects of exercises in activating lymphatic system on symptom distress and HRQoL among patients with HF. Methods and results: This was a pre-determined, secondary analysis of the TOLF-HF [The-Optimal-Lymph-Flow for Heart Failure (TOLF-HF)] study, a two-arm pilot randomized controlled trial evaluating the preliminary effects of the lymphatic exercise intervention in enhancing interstitial decongestion among patients with HF. Participants were randomized to receive either a four-week TOLF-HF program in addition to standard care or standard care alone. The Chinese version of the Minnesota Living with Heart Failure Questionnaire (MLHFQ) was employed to measure symptom distress and HRQoL before and after the intervention. Data analyses included descriptive statistics, the independent sample t-test, Pearson's chi-square test, the Mann-Whitney U test, and covariance analysis. Of the 66 patients enrolled, 60 completed the study. The study results exhibited that the TOLF-HF intervention were effective in alleviating both physical and psychological symptom distress. The intervention group yielded significantly lower MLHFQ total scores in comparison to the control group. The odd ratio of achieving meaningful improvement in HRQoL in TOLF-HF group was 2.157 times higher than those in the control group. Conclusions: The TOLF-HF program focusing on activating lymphatic system was effective in alleviating physical and psychological symptom distress as well as improving HRQoL for patients with HF. The tolerability, feasibility, and effectiveness of the TOLF-HF intervention make it a promising intervention for patients to manage HF.

Exercises in activating lymphatic system on fluid overload symptoms, abnormal weight gains, and physical functions among patients with heart failure: A randomized controlled trial.

Background: Fluid overload remains a vexing problem in management of heart failure. The lymphatic system that plays the central role in fluid homeostasis has recently been explored as a potential target to counteract tissue fluid overload. The goal of the study was to evaluate the preliminary effects of exercises in activating lymphatic system on fluid overload symptoms, abnormal weight gains, and physical functions for patients with heart failure. Methods and results: A pilot, pre- and post-test, randomized clinical trial was conducted to recruit a total of 66 patients who were randomized to receive either a 4-week The-Optimal-Lymph-Flow for Heart Failure (TOLF-HF) program or usual care alone. The primary outcome was the prevalence and burden of the fluid overload symptoms. Findings of the trial showed that the TOLF-HF intervention was effective in reducing the prevalence or burden of the majority of fluid overload symptoms. TOLF-HF intervention also demonstrated significant improvement in the outcomes of abnormal weight gains (MD: -0.82; 95% CI: -1.43 to -0.21; P = 0.010) and physical functions (F = 13.792, P < 0.001). Conclusions: The TOLF-HF program focusing on activating lymphatic system through the performance of therapeutic lymphatic exercises holds the promise as an adjuvant therapy for patients with heart failure to manage fluid overload symptoms, reduce abnormal weight gains, and improve physical functions. Future larger-scale study with longer duration of follow-up is needed. Clinical Trial Registration: http://www.chictr.org.cn/index.aspx, identifier ChiCTR2000039121.

Relationship of Earthquake Exposure, Locus of Control, Coping Strategy, and Posttraumatic Stress Disorder Among Adolescent Survivors.

A cross-sectional study was performed to examine the incidence of posttraumatic stress disorder (PTSD) among adolescent survivors 2 years after the 2017 Jiuzhaigou earthquake, and to identify risk factors and their interaction effects. A total of 4,131 adolescents were recruited. PTSD was assessed using the PTSD Checklist-Civilian Version, and locus of control (LOC) and coping strategy were assessed using the Internality, Powerful Others and Chance Scale and Coping Styles Scale, respectively. The prevalence of PTSD was 5% and the relationship between external LOC and PTSD and negative coping and PTSD seemed moderated by environmental factors. These factors should be considered along with external LOC, especially among adolescents with high levels of earthquake exposure. Positive coping strategies may help adolescents manage stress after a severe earthquake. [Journal of Psychosocial Nursing and Mental Health Services, 60(11), 41-47.].

Effect of nurse-led hospital-to-home transitional care interventions on mortality and psychosocial outcomes in adults with heart failure: a meta-analysis.

AIMS: To determine the effectiveness and dose-response of nurse-led hospital-to-home transitional care interventions (TCIs) on patient mortality and psychosocial outcomes of health-related quality of life (HRQoL), self-care behaviours, and emotional well-being in adults hospitalized with heart failure (HF) and to recognize pertinent characteristics that potentially affect the overall effectiveness. METHODS AND RESULTS: Relevant studies were identified through electronic database searches, including MEDLINE, Embase, CINAHL, and Cochrane Library from January 2000 until January 2021. Two independent authors performed study selection, data abstraction, and risk-of-bias assessment. When appropriate, we used random-effects meta-analysis to derive pooled effect estimates, investigated dose-response relationships, and ran meta-regressions to locate the source of heterogeneity. A total of 27 studies with 7635 participants were included. Our findings revealed that nurse-led hospital-to-home TCIs reduced the risk of all-cause mortality by 21% [risk ratio = 0.79; 95% confidence interval (CI) 0.68-0.92; P = 0.003] and improved HRQoL (mean difference = -3.29; 95% CI -6.51 to -0.07; P = 0.04) compared to usual care, but non-significant effects were found for emotional well-being. The narrative summary of evidence for self-care behaviours showed positive intervention effects. Meta-regression did not find any covariates that were significantly related to mortality or HRQoL. Dose-response analysis showed that mortality risk was reduced with increased intensity and complexity of the nurse-led TCIs. CONCLUSION: Generally, nurse-led hospital-to-home TCIs may play a beneficial role in decreasing mortality, and improving HRQoL and self-care behaviours for adults with HF. Additional studies are warranted to characterize the optimal nurse-led TCIs for HF management.

Effects of nurse-led transitional care interventions for patients with heart failure on healthcare utilization: A meta-analysis of randomized controlled trials.

BACKGROUND: Heart failure (HF) imposes a substantial burden on patients and healthcare systems. Hospital-to-home transitional care, involving time-limited interventions delivered predominantly by nurses, was introduced to lighten this burden. This study aimed to examine the effectiveness and dose-response of nurse-led transitional care interventions (TCIs) on healthcare utilization among patients with HF. METHODS: Health-related databases were systematically searched for articles published from January 2000 to June 2020. We included randomized controlled trials (RCTs) that compared nurse-led TCIs with usual care for adults hospitalized with HF and reported the following healthcare utilization outcomes: all-cause readmissions, HF-specific readmissions, emergency department visits, or length of hospital stay. Random-effects meta-analysis, meta-regression analysis, and dose-response analysis were performed to estimate the treatment effects and explain the heterogeneity. RESULTS: Twenty-five RCTs including 8422 patients with HF were included. Nurse-led TCIs for patients with HF resulted in a mean 9% (RR = 0.91; 95% CI = 0.82 to 0.99; p = 0.04; I2 = 46%) and 29% (RR = 0.71; 95% CI = 0.60 to 0.84; p < 0.0001; I2 = 0%) reduction in all-cause and HF-specific readmission risks respectively compared to usual care. The interventions were also effective in shortening the length of hospital stay (MD = -2.37; 95% CI = -3.16 to -1.58; p < 0.0001; I2 = 14%). However, no significant reduction was found for emergency department visits (RR = 0.96; 95% CI = 0.84 to 1.10; p = 0.58; I2 = 0%). The effect of meta-regression coefficients on all-cause and HF-specific readmissions was not statistically significant for any prespecified trial-level characteristic. Dose-response analysis revealed that the HF-specific readmission risk decreased in a dose-dependent manner with the complexity and intensity of nurse-led TCIs. CONCLUSIONS: Nurse-led TCIs were effective in decreasing all-cause and HF-specific readmission risks, as well as in reducing the length of hospital stay; however, the interventions were not effective in reducing the frequency of emergency department visits.

The Effectiveness of Transitional Care Interventions on Health Care Utilization in Patients Discharged From the Hospital With Heart Failure: A Systematic Review and Meta-Analysis.

OBJECTIVES: Heart failure (HF) heavily burdens the global health system. Transitional care interventions attempt to streamline the hospital-to-home transition to ease the burden. This systematic review and meta-analysis aimed to evaluate the effectiveness of transitional care interventions on health care utilization after hospitalization for HF. DESIGN: Systematic review and meta-analysis including dose-response relationship. SETTING AND PARTICIPANTS: Randomized controlled trials (RCTs) of transitional care interventions vs usual care in older patients discharged from the hospital with HF. METHODS: Electronic databases including MEDLINE, Embase, Cochrane Library, and CINAHL, were systematically searched from January 2009 to October 2019 to locate relevant systematic reviews or meta-analyses. The original RCTs included in the review articles were identified, and an additional search for recently published RCTs was performed from January 2014 to June 2020. This systematic review focused on health care utilization outcomes, including hospital readmissions for HF or any cause, emergency department (ED) visits, and length of hospital stay (LOS). RESULTS: Data were summarized from 38 RCTs covering 10,871 patients. Pooled evidence suggested a mean 11% [risk ratio (RR) 0.89, 95% confidence interval (CI) 0.82, 0.97] and 22% (RR 0.78, 95% CI 0.68, 0.89) risk reduction on all-cause and HF-specific readmissions, but no significant reduction (RR 0.94, 95% CI 0.83, 1.07) on ED visits. Findings were mixed for LOS. Subgroup analysis by different types of transitional care interventions indicated that multidisciplinary interventions currently have the best evidence for reducing readmissions up to 6 months post the index HF hospitalization. In addition, we observed an inverse linear dose-response relationship between intervention intensity (ie, frequency and duration of interventions) and complexity (ie, number of intervention components) and the risk of HF readmissions. CONCLUSIONS AND IMPLICATIONS: Transitional care interventions for hospitalized patients with HF reduced all-cause and HF-specific readmissions, but did not decrease ED visits. Multidisciplinary interventions are highly recommended if adequate resources are available.
