Objective: To understand the association of maternal emotional symptoms and parent-child relationship with emotional and behavioral problems (EBPs) in primary school students, so as to provide a reference for the prevention of EBPs in primary school students. Methods: In May 2023, a convenient cluster sampling method was used to select 1 324 students from two primary schools in Hefei City, Anhui Province as the study subjects. The Generalized Anxiety Disorder-7 (GAD-7), Patient Health Questionnaire (PHQ-9), Family Adaptation and Cohesion Evaluation ScalesⅡ (FACES Ⅱ), and Strengths and Difficulties Questionnaire (SDQ) of parental version were used to investigate maternal emotional symptoms, parent-child relationship, and EBPs of primary school students, respectively. Multivariate Logistic regression analysis model was used to analyze the association of different maternal emotional symptoms and parent-child relationship with EBPs of primary school students. Results: The abnormal detection rates of emotional symptoms, conduct problems, hyperactivity disorder, peer problems, prosocial behavior and total difficulties in primary school students were 13.6%, 19.4%, 20.2%, 36.5%, 20.9% and 51.9%, respectively. Multivariate Logistic regression analysis showed that the detection rates of EBPs in primary school students whose mothers had anxiety and depression symptoms with low level of parent-child relationship increased ( OR=1.52-6.97, P <0.01). The combined effect of mothers who had anxiety and depression symptoms with low level of parent-child relationship increased the risk of EBPs in all dimensions of primary school students ( OR=4.07-10.14, P <0.01). After gender stratification, the combined effect of mothers who had anxiety and depression symptoms with low level of parent-child relationship increased the risk of EBPs in all dimensions of boys and girls ( OR=3.71- 10.95 , P <0.01). Conclusions Maternal emotional symptoms and parent-child relationship are associated with EBPs in primary school students. Reducing maternal anxiety and depression symptoms, and improving parent-child relationship are beneficial to reduce the incidence of EBPs problems in primary school students.

Objective To investigate the nutritional status of the elderly population in an elderly care institution in Jiangning District of Nanjing City, and analyze the relevant influencing factors, and to provide theoretical guidance for the prevention and control of malnutrition in the elderly population. Methods A total of 1 040 elderly individuals who were admitted to the Nanjing Jiangning Muchun Garden Nursing Home from September 2019 to December 2023 were included as the study subjects. According to the evaluation scores using the Mini Nutrition Assessment Short Form (MNA-SF), the elderly people were divided into a normal nutrition group, a malnutrition risk group , and a malnutrition group . The differences in general condition, dietary intake or elderly syndromes such as anxiety, depression , and activity ability among the three groups of study subjects were compared and analyzed . Results The incidence of malnutrition in the elderly was 15.87%. There were differences in the incidence of malnutrition among the elderly population with different educational levels, marital status, and pre-retirement occupations. The frequency of intake of fresh fruits, fresh vegetables, and dairy products in the malnutrition group of the elderly population was lower than that in the normal nutrition group. The proportion of elderly people with malnutrition and poor sleep quality was higher than that of those with normal nutrition. In addition, the proportion of elderly people with malnutrition, moderate or above depression, and moderate action dependence was also higher than that of those with normal nutrition (P<0.05). The logistic regression results showed that an increase in educational level, a decrease in dairy product intake, and an exacerbation of depression and disability levels were risk factors for malnutrition in the elderly population (OR>1), while good sleep quality was protective factor for malnutrition in the elderly population (OR<1). Conclusion The incidence of malnutrition among elderly people in a nursing home in Nanjing is relatively high. Low frequency of dairy intake, depression, and disability are independent influencing factors for malnutrition among elderly people in this nursing home.

Objective:To investigate the incidence of postoperative complications in Chinese patients with gastric or colorectal cancer, and to evaluate the risk factors for postoperative complications.Methods:This was a national, multicenter, prospective, registry-based, cohort study of data obtained from the database of the Prevalence of Abdominal Complications After Gastro- enterological Surgery (PACAGE) study sponsored by the China Gastrointestinal Cancer Surgical Union. The PACAGE database prospectively collected general demographic characteristics, protocols for perioperative treatment, and variables associated with postoperative complications in patients treated for gastric or colorectal cancer in 20 medical centers from December 2018 to December 2020. The patients were grouped according to the presence or absence of postoperative complications. Postoperative complications were categorized and graded in accordance with the expert consensus on postoperative complications in gastrointestinal oncology surgery and Clavien-Dindo grading criteria. The incidence of postoperative complications of different grades are presented as bar charts. Independent risk factors for occurrence of postoperative complications were identified by multifactorial unconditional logistic regression.Results:The study cohort comprised 3926 patients with gastric or colorectal cancer, 657 (16.7%) of whom had a total of 876 postoperative complications. Serious complications (Grade III and above) occurred in 4.0% of patients (156/3926). The rate of Grade V complications was 0.2% (7/3926). The cohort included 2271 patients with gastric cancer with a postoperative complication rate of 18.1% (412/2271) and serious complication rate of 4.7% (106/2271); and 1655 with colorectal cancer, with a postoperative complication rate of 14.8% (245/1655) and serious complication rate of 3.0% (50/1655). The incidences of anastomotic leakage in patients with gastric and colorectal cancer were 3.3% (74/2271) and 3.4% (56/1655), respectively. Abdominal infection was the most frequently occurring complication, accounting for 28.7% (164/572) and 39.5% (120/304) of postoperative complications in patients with gastric and colorectal cancer, respectively. The most frequently occurring grade of postoperative complication was Grade II, accounting for 65.4% (374/572) and 56.6% (172/304) of complications in patients with gastric and colorectal cancers, respectively. Multifactorial analysis identified (1) the following independent risk factors for postoperative complications in patients in the gastric cancer group: preoperative comorbidities (OR=2.54, 95%CI: 1.51-4.28, P<0.001), neoadjuvant therapy (OR=1.42, 95%CI:1.06-1.89, P=0.020), high American Society of Anesthesiologists (ASA) scores (ASA score 2 points:OR=1.60, 95% CI: 1.23-2.07, P<0.001, ASA score ≥3 points:OR=0.43, 95% CI: 0.25-0.73, P=0.002), operative time >180 minutes (OR=1.81, 95% CI: 1.42-2.31, P<0.001), intraoperative bleeding >50 mL (OR=1.29,95%CI: 1.01-1.63, P=0.038), and distal gastrectomy compared with total gastrectomy (OR=0.65,95%CI: 0.51-0.83, P<0.001); and (2) the following independent risk factors for postoperative complications in patients in the colorectal cancer group: female (OR=0.60, 95%CI: 0.44-0.80, P<0.001), preoperative comorbidities (OR=2.73, 95%CI: 1.25-5.99, P=0.030), neoadjuvant therapy (OR=1.83, 95%CI:1.23-2.72, P=0.008), laparoscopic surgery (OR=0.47, 95%CI: 0.30-0.72, P=0.022), and abdominoperineal resection compared with low anterior resection (OR=2.74, 95%CI: 1.71-4.41, P<0.001). Conclusion:Postoperative complications associated with various types of infection were the most frequent complications in patients with gastric or colorectal cancer. Although the risk factors for postoperative complications differed between patients with gastric cancer and those with colorectal cancer, the presence of preoperative comorbidities, administration of neoadjuvant therapy, and extent of surgical resection, were the commonest factors associated with postoperative complications in patients of both categories.

Objective:To provide evidence-based recommendations for the prevention and management of lower limb ischemia in veno-arterial extracorporeal membrane oxygenation (VA-ECMO) patients during treatment according to search, evaluate, and summarize the best evidence on the prevention and management of lower limb ischemia in patients with VA-ECMO.Methods:Based on the PIPOST framework (population, intervention, professional, outcome, setting, and type of evidence), an evidence-based question was formulated. A systematic search was conducted according to the "6S" evidence pyramid model in both domestic and international databases, as well as professional association websites, for all evidence related to the prevention and management of lower limb ischemia in VA-ECMO patients (aged ≥18 years). The types of evidence included clinical decisions, guidelines, expert consensus, systematic reviews, evidence summaries, and original studies. The search was conducted from the construction of the databases to February 2024. Two researchers independently conducted a literature quality evaluation, extracted and summarized evidence from the studies that met the quality criteria.Results:A total of 13 articles were included, consisting of 3 clinical decisions, 3 guidelines, 3 expert consensus, 3 systematic reviews, and 1 randomized controlled trial. A total of 18 pieces of evidence in 7 dimensions were summarized, including risk factors of VA-ECMO lower limb ischemia, evaluation before catheterization, evaluation and monitoring during treatment, prevention of lower limb ischemia, treatment of lower limb ischemia, management of distal perfusion catheter (DPC), and monitoring after VA-ECMO weaning.Conclusion:This evidence summary provides evidence-based recommendations for the prevention and management of lower limb ischemia in VA-ECMO patients, aiming to assist clinical healthcare professionals in developing tailored strategies for the prevention and management of lower limb ischemia based on during VA-ECMO support.

Objective To explore the mediating effect of positive coping styles on the relationship between resilience and vicarious trauma in nurses in Intensive Care Unit (ICU). Methods Nurses in ICU were recruited through convenience sampling and surveyed by the general information questionnaire, the Disaster Relief Vicarious Trauma Scale, the Resilience Scale, and the Simplified Coping Style Questionnaire. Results For the 242 nurses in ICU, the mean score of vicarious trauma was (85.02±19.54), the mean score of resilience was (65.47±16.37), and the mean scores of positive and negative coping styles were (25.10±6.52) and (13.65±5.29) respectively. Vicarious trauma was negatively correlated with resilience and positive coping styles (r=-0.49, -0.41, P < 0.01), while resilience was positively correlated with both positive and negative coping styles (r=0.62, 0.35, P < 0.01). Bootstrap test results showed that positive coping styles mediated 24.5% of the total effect between resilience and vicarious trauma. Conclusion Nurses in ICU have a high level of vicarious trauma, and their positive coping styles partially mediate the relationship between resilience and vicarious trauma. Clinical nursing managers should emphasize enhancing ICU nurses' resilience and positive coping abilities, implementing strategies to prevent vicarious trauma, and improving their physical and mental health.

Objective:To evaluate the outcome of laser coagulation under fetoscope for placental chorioangioma (CA).Methods:The clinical data of three pregnant women with giant CA treated by laser coagulation under fetoscope in Peking University Third Hospital from January 2018 to December 2020 were analyzed retrospectively. Relevant articles up to September 2022 were retrieved from Wanfang Database, China National Knowledge Infrastructure and PubMed, and the clinical data of all patients were retrospectively summarized. Indications and intervention effects of fetoscopic laser therapy were analyzed. Descriptive statistics was used to describe the data.Results:Thirteen patients were involved in this study including 10 cases retrieved from the databases. The average age of the pregnant women was (30.3±6.2) years old. There were 12 cases of single pregnancy and one case of twin pregnancy (monochorionic diamnionic twin pregnancy). Except for cases for which data were not available in the literatures, at the diagnosis of CA, the average gestational age was (19.9±4.5) weeks ( n=7) and the average maximum diameter of the mass was (6.1±4.1) cm ( n=6). The patients underwent fetoscopic laser therapy at an average gestational age of (25.0±2.0) weeks ( n=13) with the average maximum tumor diameter of (7.6±2.8) cm ( n=9). After treatment, the amniotic fluid volume of three cases decreased to normal. In one case, the amniotic fluid volume decreased but was still above the upper limit of the normal range. Moreover, the maximum tumor diameter decreased in four cases; the peak systolic velocity of the fetal middle cerebral artery decreased to normal in one case; fetal heart function became normal in two cases and fetal edema was relieved in one case. Among the three patients treated in our hospital, the blood supply of CA disappeared after treatment. Intrauterine fetal death occurred in two cases. The other 11 patients gave birth to live babies at the gestational age of (36.6±3.8) weeks with five through cesarean section (5/11), five through vaginal delivery (4/11) and two not reported. The birth weight of the neonates was (2 712±1 023) g and all of them survived. The gender of five neonates were reported and all were females, two of them were monochorionic diamnionic twins. No abnormality was found in the three neonates delivered in our hospital during a six-month follow-up. No abnormality was reported in the other neonates during ten days to six months of follow-up. Conclusions:Fetoscopic laser coagulation may help reduce the size of CA, decrease complications and improve pregnancy outcomes.

Objective    To investigate the feasibility of magnamosis rings designed based on magnetic compression technique in esophageal anastomosis reconstruction. Methods    According to the anatomical characteristics of esophagus in SD rats, the esophageal magnamosis rings were designed. SD rats were used as animal models (n=10, 5 males and 5 females) to complete the magnetic anastomosis reconstruction of the cervical esophagus using magnamosis rings, and the operation time, animal survival, postoperative complications, magnetic rings excretion time were recorded. Two weeks after operation, the rats were killed, and the esophageal anastomotic specimens were obtained. The blasting pressure of the anastomotic site was measured and the formation of the anastomotic site was observed with naked eyes. Results    Esophageal magnamosis was successfully performed in 10 SD rats, and the median operation time was 11 (8-13) min. All rats survived without anastomotic leakage, anastomotic stenosis, or magnetic rings incarceration. The magnetic rings were discharged after 8 (5-10) days and the burst pressure was higher than 300 mm Hg. Visual observation showed that the anastomotic muscle healed well and the mucosa was smooth. Conclusion    The magnetic compression technique  can be used for anastomosis reconstruction of esophagus, which has the advantages of simple operation and reliable anastomosis effect, and has clinical application prospect.

Objective:To investigate the status of self-perceived burden (SPB) in renal transplant recipients and analyze its related influencing factors.Methods:From June to November 2021, the convenient sampling was used to select 203 recipients of kidney transplantation donated by citizens after death in University Town Hospital of Guangdong Provincial Hospital of Chinese Medicine. The general condition questionnaire, self-perceived burden, social support and self-efficacy questionnaire were used for measurement. Univariate analysis and multiple linear stepwise regression were used to analyze the influencing factors of SPB.Results:The SPB score of 203 renal transplant recipients was 20.00 (14.00, 28.00) and 53.2% (108/203) of renal transplant recipients had varying degrees of SPB. Univariate analysis showed that there were significant differences in SPB scores among renal transplant recipients with different ages, marital status, occupational status and family monthly income ( P<0.01) , SPB were negatively correlated with social support and self-efficacy ( P<0.01) . Multiple linear stepwise regression analysis showed that age, family monthly income and self-efficacy had negative predictive effects on SPB ( P<0.01) , which could explain 27.1% of the variation of SPB in renal transplant recipients ( F=26.043, P<0.01) . Conclusions:More than half of renal transplant recipients have different degrees of SPB. The level of SPB is higher in young recipients, low-income recipients and low self-efficacy recipients. Nursing staff should adopt specific strategies to improve the level of SPB in renal transplant recipients.
