Conservative Interventions for Urinary Incontinence on Postpartum Women: A Systematic Review and Meta-Analysis.

INTRODUCTION: Urinary incontinence (UI) is common in postpartum women and can lead to a reduced quality of life and withdrawal from fitness and exercise activities. Conservative management interventions such as pelvic floor muscle training (PFMT), use of vaginal cones, and biofeedback have been recommended as first-line treatment. We aimed to explore the effects of conservative interventions on UI rate, severity, and incontinence-specific quality of life in postpartum women with UI. METHODS: Nine databases were searched from inception to August 2022: PubMed, EMBASE, Web of Science, Cochrane Central Register of Controlled Trials, CINAHL, Wanfang, China National Knowledge Infrastructure, China Biological Medicine, and VIP Journal Integration Platform. Randomized controlled trials examining the effects of conservative interventions on postpartum UI were included. RESULTS: Initial searches produced 1839 results, of which 17 studies were eligible. All included studies had a low to moderate risk of bias. Supervised PFMT and use of a vaginal cone were more effective than individual PFMT in decreasing rates of UI (odds ratio, 0.29; 95% CI, 0.14-0.61). Individual PFMT combined with acupuncture (mean difference, -1.91; 95% CI, -2.46 to -1.37) or electroacupuncture and supervised PFMT combined with moxibustion were more effective than individual supervised PFMT alone in improving the severity of symptoms. Furthermore, electrical stimulation and biofeedback combined with acupoint stimulation or core training were more effective than electrical stimulation and biofeedback alone. For improving the incontinence-specific quality of life, supervised PFMT was more efficacious than individual PFMT; electrical stimulation and biofeedback plus core training were more beneficial than electrical stimulation and biofeedback alone. DISCUSSION: Supervised PFMT and use of a vaginal cone were more beneficial in decreasing rates of UI compared with individual PFMT. Superior effects in decreasing UI severity may be achieved by combining PFMT or electrical simulation and biofeedback with other therapies. Electrical stimulation and biofeedback plus core training, as well as supervised PFMT, are most effective in improving incontinence-specific quality of life. Further research is required to provide more evidence on the efficacy of these therapies.

A scale for measuring nursing digital application skills: a development and psychometric testing study.

BACKGROUND: The adoption of digitization has emerged as a new trend in the advancement of healthcare systems. To ensure high-quality care, nurses should possess sufficient skills to assist in the digital transformation of healthcare practices. Suitable tools have seldom been developed to assess nurses' skills in digital applications. This study aimed to develop the Nursing Digital Application Skill Scale (NDASS) and test its psychometric properties. METHODS: The Nursing Digital Application Skill Scale was developed in three phases. In Phase 1, an item pool was developed based on previous literature and the actual situation of nursing work. Phase 2 included 14 experts' assessment of content validity and a focus group interview with 30 nurses to pretest the scale. In phase 3, 429 registered nurses were selected from March to June 2023, and item analysis, exploratory factor analysis, and confirmatory factor analysis were used to refine the number of items and explore the factor structure of the scale. Additionally, reliability was determined by internal consistency and test-retest reliability. RESULTS: The final version of the NDASS consisted of 12 items. The content validity index of NDASS reached 0.975 at an acceptable level. The convergent validity test showed that the average variance extracted value was 0.694 (> 0.5) and the composite reliability value was 0.964 (> 0.7), both of which met the requirements. The principal component analysis resulted in a single-factor structure explaining 74.794% of the total variance. All the fitting indices satisfied the standard based upon confirmatory factor analyses, indicating that the single-factor structure contributed to an ideal model fit. The internal consistency appeared high for the NDASS, reaching a Cronbach's alpha value of 0.968. The test-retest reliability was 0.740, and the split-half coefficient was 0.935. CONCLUSION: The final version of the NDASS, which possesses adequate psychometric properties, is a reliable and effective instrument for nurses to self-assess digital skills in nursing work and for nursing managers in designing nursing digital skill training.

Nasal oxidative stress mediating the effects of colder temperature exposure on pediatric asthma symptoms.

BACKGROUND: Colder temperature exposure is a known trigger for pediatric asthma exacerbation. The induction of oxidative stress is a known pathophysiologic pathway for asthma exacerbation. However, the role of oxidative stress in linking colder temperature exposure and worsened pediatric asthma symptoms is poorly understood. METHODS: In a panel study involving 43 children with asthma, aged 5-13 years old, each child was visited 4 times with a 2-week interval. At each visit, nasal fluid, urine, and saliva samples were obtained and measured for biomarkers of oxidative stress in the nasal cavity (nasal malondialdehyde [MDA]), the circulatory system (urinary MDA), and the oral cavity (salivary MDA). Childhood Asthma-Control Test (CACT) was used to assess asthma symptoms. RESULTS: When ambient daily-average temperature ranged from 7 to 18 °C, a 2 °C decrement in personal temperature exposures were significantly associated with higher nasal MDA and urinary MDA concentrations by 47-77% and 6-14%, respectively. We estimated that, of the decrease in child-reported CACT scores (indicating worsened asthma symptoms and asthma control) associated with colder temperature exposure, 14-57% were mediated by nasal MDA. CONCLUSION: These results suggest a plausible pathway that colder temperature exposure worsens pediatric asthma symptoms partly via inducing nasal oxidative stress. IMPACT: The role of oxidative stress in linking colder temperature exposure and worsened asthma symptoms is still poorly understood. Lower temperature exposure in a colder season was associated with higher nasal and systemic oxidative stress in children with asthma. Nasal MDA, a biomarker of nasal oxidative stress, mediated the associations between colder temperature exposures and pediatric asthma symptoms. The results firstly suggest a plausible pathway that colder temperature exposure worsens pediatric asthma symptoms partly via inducing oxidative stress in the nasal cavity.

Key oncogenic signaling pathways affecting tumor-infiltrating lymphocytes infiltration in hepatocellular carcinoma: basic principles and recent advances.

The incidence of hepatocellular carcinoma (HCC) ranks first among primary liver cancers, and its mortality rate exhibits a consistent annual increase. The treatment of HCC has witnessed a significant surge in recent years, with the emergence of targeted immune therapy as an adjunct to early surgical resection. Adoptive cell therapy (ACT) using tumor-infiltrating lymphocytes (TIL) has shown promising results in other types of solid tumors. This article aims to provide a comprehensive overview of the intricate interactions between different types of TILs and their impact on HCC, elucidate strategies for targeting neoantigens through TILs, and address the challenges encountered in TIL therapies along with potential solutions. Furthermore, this article specifically examines the impact of oncogenic signaling pathways activation within the HCC tumor microenvironment on the infiltration dynamics of TILs. Additionally, a concise overview is provided regarding TIL preparation techniques and an update on clinical trials investigating TIL-based immunotherapy in solid tumors.

Altered gray matter volume and functional connectivity in adolescent borderline personality disorder with non-suicidal self-injury behavior.

BACKGROUND AND OBJECTIVES: Non-suicidal self-injury (NSSI) behavior is one of the characteristics of borderline personality disorder (BPD) in adolescents. Prior studies have shown that adolescents with BPD may have a unique pattern of brain alterations. The purpose of this study was to investigate the alterations in brain structure and function including gray matter volume and resting-state functional connectivity in adolescents with BPD, and to assess the association between NSSI behavior and brain changes on neuroimaging in adolescents with BPD. METHODS: 53 adolescents with BPD aged 12-17 years and 39 age-gender matched healthy controls (HCs) were enrolled into this study. Brain magnetic resonance imaging (MRI) was acquired with both 3D-T1 weighted structural imaging and resting-state functional imaging. Voxel-based morphometry (VBM) analysis for gray matter volume and seed-based functional connectivity (FC) analysis were performed for assessing gray matter volume and FC. Clinical assessment for NSSI, mood, and depression was also obtained. Correlative analysis of gray matter alterations with self-injury or mood scales were performed. RESULTS: There were reductions of gray matter volume in the limbic-cortical circuit and default mode network in adolescents with BPD as compared to HCs (FWE P < 0.05, cluster size ≥ 1000). The diminished gray matter volumes in the left putamen and left middle occipital gyrus were negatively correlated with NSSI in adolescents with BPD (r = - 0.277 and P = 0.045, r = - 0.422 and P = 0.002, respectively). Furthermore, there were alterations of FC in these two regions with diminished gray matter volumes (voxel P < 0.001, cluster P < 0.05, FWE corrected). CONCLUSIONS: Our results suggest that diminished gray matter volume of the limbic-cortical circuit and default mode network may be an important neural correlate in adolescent BPD. In addition, the reduced gray matter volume and the altered functional connectivity may be associated with NSSI behavior in adolescents with BPD.

A qualitative study exploring partner involvement in the management of gestational diabetes mellitus: The experiences of women and partners.

AIMS: The aims of the study were to explore the experiences of women with gestational diabetes mellitus (GDM) and their partners and examine the factors influencing partner involvement in GDM management, seeking to inform a targeted couple-based intervention. DESIGN: A descriptive qualitative study. METHODS: We conducted semi-structured interviews with 14 women with GDM and their partners. Participants were recruited through convenience sampling from a tertiary hospital in Xi'an, China. Data were analysed using thematic analysis. RESULTS: Three themes and 12 subthemes were identified. Theme I: Women's expectations of their partner's involvement in GDM management-practical support and emotional support. Theme II: Partner involvement in GDM management-constructive involvement, unhelpful involvement with good intentions and insufficient involvement. Theme III: Factors that influence partner involvement in GDM-knowledge of GDM, GDM risk perception, health consciousness, attitudes towards the treatment plan, couple communication regarding GDM management, family roles and appraisal of GDM management responsibility. CONCLUSION: Women desired practical and emotional support from partners. The types of partner involvement in GDM management varied. Some partners provided constructive support, while some partners' involvement was limited, non-existent or actively unhelpful. By combining these results with the factors influencing partner involvement, our findings may help healthcare professionals develop strategies to involve partners in GDM care and enhance women's ability to manage GDM. IMPLICATIONS FOR THE PROFESSION AND PATIENT CARE: Partner involvement in GDM care may help them understand and better attend to women's needs, thus improving their experience and potential outcomes. This study highlights novel factors that need to be considered in developing couple-based interventions for this population. REPORTING METHOD: The reporting follows the COREQ checklist. PATIENT OR PUBLIC CONTRIBUTION: Some patients were involved in data interpretation. There is no public contribution.

Effects of Psychological Nursing Combined with Comprehensive Nursing on Gastrointestinal Bleeding and Nutritional Status in Cirrhosis.

Objective: Cirrhosis of the upper GIB is a surgical emergency, PN and CN can reduce the risk of gastrointestinal bleeding, but there is a lack of analysis on PN combined with CN in Cirrhotic patients. This work explored the effects of psychological nursing (PN) combined with comprehensive nursing (CN) on gastrointestinal bleeding (GIB) and nutritional status of patients with cirrhosis. Methods: Total 80 patients with GIB and cirrhosis who received emergency treatment in the Affiliated Hospital of Shaoxing University from October 2019 to October 2022 were randomly rolled into two groups. Patients in the control group (Ctrl group) received CN (n = 40 cases), and those in the experimental group (Exp group) received PN combined CN (n = 40 cases). The Model for end-stage liver disease (MELD) score, self-rating anxiety scale (SAS), self-rating depression scale (SDS), SCL-90, complication rate, and nursing satisfaction of patients from different groups were analyzed and compared. MELD score effectively predicts short - and medium-term mortality in end-stage liver disease. SAS consisted of 20 questions related to anxiety symptoms, four-level scoring method was adopted. The SCL-90 scale included four aspects: somatic symptoms, interpersonal relationships, psychological emotions, and psychological needs. Results: The results disclosed that after nursing intervention, SAS, SDS, and MELD scores in the Exp group were remarkably lower than those in the Ctrl group (P < .05). The scores of SCL-90 somatic symptoms, interpersonal relationships, psychological emotion, and psychological needs of participants in the Exp group were much lower than those in the Ctrl group (P < .05). The complication rate was significantly lower in the Exp (30.0%) than in the Ctrl groups (72.5%) (P < .05). The total nursing satisfaction was increased, and it is significan higher in the Exp group (97.5%) than control group (87.5% ) (P < .05). Conclusions: In conclusion, PN combined with CN could effectively reduce the incidence of complications in patients with GIB and cirrhosis and improve nursing satisfaction. Therefore, such a method was worth promoting, which provides a reference for the clinical diagnosis and treatment of patients with GIB and cirrhosis.

Associations between personal apparent temperature exposures and asthma symptoms in children with asthma.

Ambient temperature and relative humidity can affect asthma symptoms. Apparent temperature is a measure of temperature perceived by humans that takes into account the effect of humidity. However, the potential link between personal exposures to apparent temperature and asthma symptoms has not been investigated. We conducted a panel study of 37 asthmatic children, aged 5-11 years, during an early spring season (average daily ambient temperature: 14°C, range: 7-18°C). Asthma symptoms were measured 4 times for each participant with a 2-week interval between consecutive measurements using the Childhood Asthma-Control Test (C-ACT). Average, minimum, and maximum personal apparent temperature exposures, apparent temperature exposure variability (TV), and average ambient temperature were calculated for the 12 hours, 24 hours, week, and 2 weeks prior to each visit. We found that a 10°C lower in 1-week and 2-week average & minimum personal apparent temperature exposures, TV, and average ambient temperature exposures were significantly associated with lower total C-ACT scores by up to 2.2, 1.4, 3.3, and 1.4 points, respectively, indicating worsened asthma symptoms. Our results support that personal apparent temperature exposure is potentially a stronger driver than ambient temperature exposures for the variability in asthma symptom scores. Maintaining a proper personal apparent temperature exposure could be an effective strategy for personalized asthma management.

Associations between home environmental factors and childhood eczema and related symptoms in different cities in China.

Previous studies have shown significant associations between home environmental factors and childhood eczema. However, few studies have compared how associations differ in different regions. This study investigated associations between home environmental factors and childhood eczema ever, and related symptoms including itchy rash (IR) and being awakened by itchy rash at night (awake by IR) in 4 cities located in different regions of China, based on cross-sectional investigations during 2010-2012. We used two-step analysis to explore the associations between influencing factors and eczema/related symptoms: first, group Least Absolute Shrinkage and Selection Operator (LASSO) was conducted to identify important factors among a list of candidates; then, the associations in total study population and in each city were estimated using logistic regression. We found these home environmental factors to be risk factors for eczema or related symptoms: large residence size, shared room, air cleaner at home, abnormal smell, perceived dry air, visible mold or damp stains, cooking with coal or wood, painted wall, incense, mice, new furniture during pregnancy, abnormal smell at birth, window condensation at birth and environmental tobacco smoke at birth. Environmental protective factors were rural house location and window ventilation. Associations of factors with eczema/related symptoms differed across cities. For example, air conditioning was protective for eczema in Beijing and awakening by IR in Shanghai with ORs of 0.70 (95%CI: 0.52, 0.95) and 0.33 (95%CI: 0.14, 0.81) respectively, but not significant in other cities. Our results have implications for improving home environments to reduce the risk of childhood eczema/related symptoms in different regions of China.

The burden of disease attributable to indoor air pollutants in China from 2000 to 2017.

BACKGROUND: High-level exposure to indoor air pollutants (IAPs) and their corresponding adverse health effects have become a public concern in China in the past 10 years. However, neither national nor provincial level burden of disease attributable to multiple IAPs has been reported for China. This is the first study to estimate and rank the annual burden of disease and the financial costs attributable to targeted residential IAPs at the national and provincial level in China from 2000 to 2017. METHODS: We first did a systematic review and meta-analysis of 117 articles from 37 231 articles identified in major databases, and obtained exposure-response relationships for the candidate IAPs. The exposure levels to these IAPs were then collected by another systematic review of 1864 articles selected from 52 351 articles. After the systematic review, ten IAPs with significant and robust exposure-response relationships and sufficient exposure data were finally targeted: PM2·5, nitrogen dioxide, sulphur dioxide, ozone, carbon monoxide, radon, formaldehyde, benzene, toluene, and p-dichlorobenzene. The annual exposure levels in residences were then evaluated in all 31 provinces in mainland China continuously from 2000 to 2017, using the spatiotemporal Gaussian process regression model to analyse indoor originating IAPs, and the infiltration factor method to analyse outdoor originating IAPs. The disability-adjusted life-years (DALYs) attributable to the targeted IAPs were estimated at both national and provincial levels in China, using the population attributable fraction method. Financial costs were estimated by an adapted human capital approach. FINDINGS: From 2000 to 2017, annual DALYs attributable to the ten IAPs in mainland China decreased from 4620 (95% CI 4070-5040) to 3700 (3210-4090) per 100 000. Nevertheless, in 2017, IAPs still ranked third among all risk factors, and their DALYs and financial costs accounted for 14·1% (95% CI 12·3-15·6) of total DALYs and 3·45% (3·01-3·82) of the gross domestic product. Specifically, the rank of ten targeted IAPs in order of their contribution to DALYs in 2017 was PM2·5, carbon monoxide, radon, benzene, nitrogen dioxide, ozone, sulphur dioxide, formaldehyde, toluene, and p-dichlorobenzene. The DALYs attributable to IAPs were 9·50% higher than those attributable to outdoor air pollution in 2017. For the leading IAP, PM2·5, the DALYs attributable to indoor origins are 18·3% higher than those of outdoor origins. INTERPRETATION: DALYs attributed to IAPs in China have decreased by 20·0% over the past two decades. Even so, they are still much higher than those in the USA and European countries. This study can provide a basis for determining which IAPs to target in various indoor air quality standards and for estimating the health and economic benefits of various indoor air quality control approaches, which will help to reduce the adverse health effects of IAPs in China. FUNDING: The National Key Research and Development Program of China and the National Natural Science Foundation of China.

The effects of a couple-based gestational diabetes mellitus intervention on self-management and pregnancy outcomes: A randomised controlled trial.

AIMS: To estimate the effectiveness of the Couples Coping with Gestational Diabetes Mellitus (GDM) Programme on GDM self-management and pregnancy outcomes. METHODS: A randomised controlled trial among pregnant women with suboptimal GDM self-management and their partners was undertaken. Couples recruited from three hospitals in China were randomly allocated to either intervention (n = 70) or control (n = 70) conditions. Couples in the intervention group underwent the couple-based intervention (GDM education, shared illness appraisals, initiation of collaborative action and consolidation of collaborative action). Women in the control group received individual GDM education. Data were analysed using the independent samples t-test, chi-square test, and generalised estimating equations. RESULTS: GDM knowledge for the women and their partners and GDM self-management significantly improved in both the intervention and control groups, with stronger improvement in the intervention group. Women in the intervention group gained significantly less weight than those in the control group (11.2 kg ± 2.8 kg vs 13.1 kg ± 2.6 kg, p = 0.008). Infant birth weights were significantly lower in the intervention group (3.2 kg ± 0.3 kg vs 3.4 kg ± 0.4 kg, p = 0.008). There were no significant differences in other pregnancy outcomes. CONCLUSIONS: The Couples Coping with GDM Programme was associated with improvements in GDM knowledge of women and their partners and in women's self-management, and with lower gestational weight gain and infant birth weight.

Adaptation and validation of the Evidence-based Practice Profile Questionnaire (EBP2Q) for clinical postgraduates in a Chinese context.

BACKGROUND: Evidence-based practice (EBP) is an essential approach of optimizing patient outcomes and driving progress in clinical practice. As an important reserve talent of medical staff and researchers, the clinical postgraduates are expected to become the backbones of supporting the implementation of EBP in clinical units after graduation. The assessment of their EBP learning outcomes is an important issue, yet few tools have been developed specifically in Mainland China. The purpose of this study is to adapt the Evidence-Based Practice Profile Questionnaire (EBP2Q) to Mainland China's cultural context and to evaluate the psychometric properties of the Chinese EBP2Q in clinical postgraduates. METHODS: Cross-cultural modification, including translating the original EBP2Q into Chinese was implemented according to established guidelines. A pilot study was carried out in Mainland China among 30 clinical postgraduates. A subsequent validation study was conducted among 633 clinical postgraduates majoring in clinical medicine, stomatology and nursing from Mainland China. Construct validity was assessed by exploratory factor analysis (n = 313), together with confirmatory factor analysis (n = 320). Reliability was determined by internal consistency and test-retest reliability. RESULTS: The Chinese EBP2Q consisted of 40 items. The content validity index of the Chinese EBP2Q achieved 0.938 at an acceptable level. Principal component analysis resulted in a four-factor structure explaining 61.586% of the total variance. All fitting indices satisfied the standard based upon confirmatory factor analyses, indicating that the four-factor structure contributed to an ideal model fit. The internal consistency appeared high for the Chinese EBP2Q, reaching a Cronbach's alpha value of 0.926. Test-retest reliability was 0.868 and the split-half coefficient was 0.925. CONCLUSION: Chinese version of EBP2Q possesses adequate validity, test-retest reliability and internal consistency. It is a promising questionnaire to be adopted by Chinese medical educators in designing their course and curriculum, or by clinical postgraduates for self-assessment of EBP learning.

An integrated non-targeted and targeted analysis approach for identification of semi-volatile organic compounds in indoor dust.

Household dust contains a wide variety of semi-volatile organic compounds (SVOCs) that may pose health risks. We developed a method integrating non-targeted analysis (NTA) and targeted analysis (TA) to identify SVOCs in indoor dust. Based on a combined use of gas and liquid chromatography with high-resolution mass spectrometry, an automated, time-efficient NTA workflow was developed, and high accuracy was observed. A total of 128 compounds were identified at confidence level 1 or 2 in NIST standard reference material dust (SRM 2585). Among them, 113 compounds had not been reported previously, and this suggested the value of NTA in characterizing contaminants in dust. Additionally, TA was done to avoid the loss of trace compounds. By integrating data obtained from the NTA and TA approaches, SVOCs in SRM 2585 were prioritized based on exposure and chemical toxicity. Six of the top 20 compounds have never been reported in SRM 2585, including melamine, dinonyl phthalate, oxybenzone, diheptyl phthalate, drometrizole, and 2-phenylphenol. Additionally, significant influences of analytical instruments and sample preparation on NTA results were observed. Overall, the developed method provided a powerful tool for identifying SVOCs in indoor dust, which is necessary to obtain a more complete understanding of chemical exposures and risks in indoor environments.

Magnetic resonance imaging findings of intracranial extraventricular ependymoma: A retrospective multi-center cohort study of 114 cases.

BACKGROUND: Intracranial extraventricular ependymoma (IEE) is an ependymoma located in the brain parenchyma outside the ventricles. IEE has overlapping clinical and imaging characteristics with glioblastoma multiforme (GBM) but different treatment strategy and prognosis. Therefore, an accurate preoperative diagnosis is necessary for optimizing therapy for IEE. METHODS: A retrospective multicenter cohort of IEE and GBM was identified. MR imaging characteristics assessed with the Visually Accessible Rembrandt Images (VASARI) feature set and clinicopathological findings were recorded. Independent predictors for IEE were identified using multivariate logistic regression, which was used to construct a diagnostic score for differentiating IEE from GBM. RESULTS: Compared to GBM, IEE tended to occur in younger patients. Multivariate logistic regression analysis identified seven independent predictors for IEE. Among them, 3 predictors including tumor necrosis rate (F7), age, and tumor-enhancing margin thickness (F11), demonstrated higher diagnostic performance with an Area Under Curve (AUC) of more than 70% in distinguishing IEE from GBM. The AUC was 0.85, 0.78, and 0.70, with sensitivity of 92.98%, 72.81%, and 96.49%, and specificity of 65.50%, 73.64%, and 43.41%, for F7, age, and F11, respectively. CONCLUSION: We identified specific MR imaging features such as tumor necrosis and thickness of enhancing tumor margins that could help to differentiate IEE from GBM. Our study results should be helpful to assist in diagnosis and clinical management of this rare brain tumor.

Effect of the physical rehabilitation program based on self-care ability in patients with acute ischemic stroke: a quasi-experimental study.

Introduction: It is the most practical goal of limb rehabilitation for stroke patients to make the upper limb, trunk, and lower limb joints link together as a whole and restore the ability to self-care. However, many previous studies focused on the single joint or single muscle group movement of stroke patients and did not integrate self-care ability training into the whole process of rehabilitation, which lacks accuracy, integrity, and systematization. Methods: A quasi-experimental study was conducted in a tertiary hospital. Eligible patients were recruited according to the inclusion criteria and exclusion criteria and then divided into an experimental group (n = 80) and a control group (n = 80) by the medical district. The control group received the routine physical rehabilitation intervention. The experimental group adopted the physical rehabilitation program based on self-care ability led by the nurses specializing in stroke rehabilitation to carry out the multi-joint coordinated exercise based on the control group. The training time and frequency were the same in both groups (45 min per session, one session per day for three consecutive months). The primary outcome was myodynamia. Secondary outcomes were the modified Barthel Index (MBI) and Stroke Specific Quality of Life Scale (SS-QOL). The primary and secondary outcomes were assessed before the intervention and at 1 and 3 months of intervention. In this study, the TREND checklist was followed for non-randomized controlled trials. Results: A total of 160 participants completed the study. The physical rehabilitation program based on self-care ability was better than the routine rehabilitation program. With the prolongation of intervention time, all outcomes improved gradually in the experimental group (P < 0.05), and the myodynamia of lower limbs recovered faster than that of upper limbs. In the control group, the myodynamia of the affected limb was not significantly improved (P > 0.05), with only a small increase in MBI and SS-QOL scores (P < 0.05). Conclusion: The physical rehabilitation program based on self-care ability after stroke was beneficial for acute ischemic stroke patients and improved the patient's myodynamia, quality of life, and self-care ability within the third month.

Analysis of the influential factors of the emotional health of patients with cancer based on the structural equation model: the role of social media and emotional support.

PURPOSE: To explore the mental health status of patients with cancer and related influential factors and provide a scientific basis to reduce serious emotional problems, improve the quality of life of cancer survivors and adopt targeted interventions. METHODS: A total of 517 patients who attended the oncology departments of six grade-A tertiary hospitals from July 2022 to September 2022 were selected by convenience sampling. The effects of emotional support, social media, patient-centred communication, health self-efficacy and cancer beliefs on the emotional well-being of patients with cancer were analysed based on the structural equation model. RESULTS: A Spearman correlation analysis showed a significant positive correlation among the six latent variables (P<0.01). The structural equation model path analysis showed that health self-efficacy (ß=0.374, P<0.001), cancer belief (ß=0.214, P=0.003) and emotional support (ß=0.104, P=0.031) all had positive effects on emotional health. The mediating effect results showed that cancer beliefs had a mediating effect on mental health in social media use (ß=0.106, P=0.001), emotional support (ß=0.028, P=0.002) and patient-centred communication (ß=0.050, P=0.002). Further, health self-efficacy had mediating effects on mental health in emotional support (ß=0.084, P=0.001) and patient-centred communication (ß=0.098, P=0.001). CONCLUSION: By constructing structural equation models, this study found that emotional support, cancer beliefs and health self-efficacy showed a positive effect on the emotional well-being of patients with cancer. Further, it found a mediating role of health cancer beliefs on the impact of emotional support, social media use and patient-centred communication on mental health. Additionally, health self-efficacy has a mediating role regarding the effects of emotional support and patient-centred communication on mental health.

Childhood pneumonia in Beijing: Associations and interactions among selected demographic and environmental factors.

Among infectious diseases, pneumonia is the greatest cause of mortality in children less than 5 years old. Approximately 27% of Beijing's 3-8 year-old children have had pneumonia at least once. The sole reservoir of pneumonia pathogens is the human nasopharynx. We investigated associations and interactions among two kinds of environmental risk factors: i) airborne pathogens, namely closed bedroom window and shared bedroom and ii) pollutants, namely traffic pollution and environmental tobacco smoke (ETS). We evaluated breastfeeding's (BF) protective value against childhood pneumonia. The database consists of responses to a questionnaire in a cross-sectional study. Crude and adjusted Odds Ratios were assessed independently for each risk factor. Combinations of the studied risk factors were analyzed using multivariate logistic regression. Risk factors were evaluated for interactions on the additive scale using the metrics Relative Excess Risk due to Interaction (RERI), Attributable Proportion (AP) and Synergy Index (S). All independent risk factors were significant for children's pneumonia. We also found evidence of possible synergistic interaction between pairs of risk factors that was stronger when one of the risk factors was a closed bedroom window. Remarkably, window opening was associated with reduced risk of pneumonia for children living near heavy traffic pollution. Longer duration BF was more protective than shorter, and exclusive BF was more protective than partial BF against childhood pneumonia. In conclusion, low ventilation (closed bedroom windows), shared bedroom, ETS, and traffic exposure were associated with increased risk of pneumonia. Exclusive BF for more than six months had the greatest protective value against pneumonia.

Student close contact behavior and COVID-19 transmission in China's classrooms.

Classrooms are high-risk indoor environments, so analysis of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) transmission in classrooms is important for determining optimal interventions. Due to the absence of human behavior data, it is challenging to accurately determine virus exposure in classrooms. A wearable device for close contact behavior detection was developed, and we recorded >250,000 data points of close contact behaviors of students from grades 1 to 12. Combined with a survey on students' behaviors, we analyzed virus transmission in classrooms. Close contact rates for students were 37 ± 11% during classes and 48 ± 13% during breaks. Students in lower grades had higher close contact rates and virus transmission potential. The long-range airborne transmission route is dominant, accounting for 90 ± 3.6% and 75 ± 7.7% with and without mask wearing, respectively. During breaks, the short-range airborne route became more important, contributing 48 ± 3.1% in grades 1 to 9 (without wearing masks). Ventilation alone cannot always meet the demands of COVID-19 control; 30 m3/h/person is suggested as the threshold outdoor air ventilation rate in a classroom. This study provides scientific support for COVID-19 prevention and control in classrooms, and our proposed human behavior detection and analysis methods offer a powerful tool to understand virus transmission characteristics and can be employed in various indoor environments.

Validation and application of the 2019 International Working Group on the Diabetic Foot risk stratification for diabetic foot in Chinese patients.

AIMS/INTRODUCTION: The purpose of the present study was to evaluate the validation and application of the 2019 International Working Group on the Diabetic Foot (IWGDF) risk stratification system among Chinese patients with diabetes. MATERIALS AND METHODS: A retrospective cohort study was carried out with 254 patients with diabetes, but without an active diabetic foot (DF) ulcer. Patients hospitalized from January to May 2017 were enrolled, and the follow-up period was from January to May 2020. Patients were stratified into four risk groups based on the 2019 IWGDF risk stratification system. RESULTS: Of the 254 patients, four of 31 patients at risk 1 were diagnosed with DF within 3 years, whereas 12 of 26 patients at risk 2 and 16 of 20 patients at risk 3 developed DF. The area under the curve was 0.919 (P < 0.01, 95% confidence interval 0.893-0.945). Because DF risk 2 and greater (risk 2 + risk 3) was the optimal cut-off point, we simplified the risk stratification system by using two tiers, namely, low risk (risk 0 + 1) and high risk (risk 2 + 3). For the simplified risk stratification system, the sensitivity, specificity, positive likelihood ratio, percent agreement, positive predictive value and negative predictive value were 87.5%, 91.8%, 10.607, 91.3%, 60.8% and 98.1%, respectively. The χ2 -test showed that the odds ratio of the high-risk group (risk 2 + 3) was 29.33-fold that of the low-risk group (risk 0 + 1). CONCLUSIONS: The 2019 IWGDF risk stratification system showed high validity and primary screening value in Chinese patients with diabetes. Thus, a simplified, two-tiered IWGDF stratification might be more efficient and cost-effective for predicting DF ulcers.
