Objective: To explore the correlation among picky eating levels in preschool children, parental self-efficacy and parenting stress. Methods: A convenience sampling method was employed to conduct an electronic questionnaire survey among 459 children aged 3-6 years and their parents from five kindergartens in Urumqi in November 2023. The survey included a general information questionnaire, the Children s Eating Behavior Questionnaire (CEBQ), the Parenting Sense of Competence Scale (PSOC), and the Parenting Stress Index-Short Form (PSI-SF). The Mann-Whitney U-test was used for twogroup comparisons, and the Kruskal-Wallis H-test was applied for multi-group comparisons. Spearman correlation analysis was conducted to examine the relationships between children s picky eating levels and parenting selfefficacy as well as parenting stress. Results: The picky eating score of preschool children was 10.00 (4.00), and the parenting self-efficacy score was 58.00 (12.00), both indicating a moderate level. The parenting stress score was 75.00 (16.00), reflecting a moderately low level. Spearman correlation analysis showed that children s picky eating levels were negatively correlated with the total score of parenting self-efficacy ( r =-0.28) and positively correlated with the total score of parenting stress( r =0.25)( P <0.01). Conclusions Picky eating levels of preschool children are closely associated with parenting self-efficacy and parenting stress. Picky eating behaviors in children can be reduced by implementing various effective measures to enhance parenting self-efficacy and alleviate parenting stress.

Volatile organic compounds (VOCs) and semi-volatile organic compounds (SVOCs) are common organic compounds in indoor and outdoor air, and enter the human body primarily through the respiratory tract and directly damage the respiratory system. Previous studies have suggested that exposure to VOCs/SVOCs may associate with the prevalence, incidence, and progression of asthma, but the extent of the associations is still vague. Furthermore, biomarkers for efficient and simple asthma diagnosis, typing, and attack prediction remain unclear at this stage. From the perspective of the collection and detection methods of VOCs/SVOCs, this paper summarized the epidemiological associations and underlying biological mechanisms between VOCs/SVOCs exposure and the prevalence, incidence, and progression of asthma in children/adults. It also demonstrated the application of VOCs/SVOCs in recent years in assisting asthma diagnosis, such as distinguishing asthma patients from the healthy population, differentiating different asthma phenotypes, and predicting asthma acute exacerbations, aiming to provide a scientific basis for improving current asthma management.

ObjectiveTo evaluate the efficacy and safety of Xiaoji Hufei Formula in protecting children with close contact exposure to influenza， and to provide reference and evidence-based support for better clinical prevention and treatment of influenza in children. MethodsA multicenter， prospective， non-randomized， parallel， controlled trial was conducted from October 2021 to May 2022 in five hospitals， including Dongfang Hospital of Beijing University of Chinese Medicine. Confirmed influenza cases and influenza-like illness （ILI） cases were collected， and eligible children with close contact exposure to these cases were recruited in the outpatient clinics. According to whether the enrolled close contacts were willing to take Xiaoji Hufei formula for influenza prevention， they were assigned to the observation group （108 cases） or the control group （108 cases）. Follow-up visits were conducted on days 7 and 14 after enrollment. The primary outcomes were the incidence of ILI and the rate of laboratory-confirmed influenza. Secondary outcomes included traditional Chinese medicine （TCM） symptom score scale for influenza， influenza-related emergency （outpatient） visit rate， influenza hospitalization rate， and time to onset after exposure to influenza cases. ResultsA total of 216 participants were enrolled， with 108 in the observation group and 108 in the control group. Primary outcomes： （1） Incidence of ILI： The incidence was 12.0% （13/108） in the observation group and 23.1% （25/108） in the control group， with the observation group showing a significantly lower incidence （χ²=4.6， P<0.05）. （2） Influenza confirmation rate： 3.7% （4/108） in the observation group and 4.6% （5/108） in the control group， with no statistically significant difference. Secondary outcomes： （1） TCM symptom score scale： after onset， nasal congestion and runny nose scores differed significantly between the two groups （P<0.05）， while other symptoms such as fever， sore throat， and cough showed no significant differences. （2） Influenza-related emergency （outpatient） visit rate： 84.6% （11 cases） in the observation group and 96.0% （24 cases） in the control group， with no significant difference. （3） Time to onset after exposure： The median onset time after exposure to index patients was 7 days in the observation group and 4 days in the control group， with a statistically significant difference （P<0.05）. ConclusionIn previously healthy children exposed to infectious influenza cases under unprotected conditions， Xiaoji Hufei formula prophylaxis significantly reduced the incidence of ILI. Xiaoji Hufei Formula can be recommended as a specific preventive prescription for influenza in children.

OBJECTIVE: To investigate the characteristics of gut microbiota changes in patients with acute myeloid leukemia (AML) undergoing induction chemotherapy and to explore the relationship between infectious complications and gut microbiota. METHODS: Fecal samples were collected from 37 newly diagnosed AML patients at four time points: before induction chemotherapy, during chemotherapy, during the neutropenic phase, and during the recovery phase. Metagenomic sequencing was used to analyze the dynamic changes in gut microbiota. Correlation analyses were conducted to assess the relationship between changes in gut microbiota and the occurrence of infectious complications. RESULTS: During chemotherapy, the gut microbiota α-diversity (Shannon index) of AML patients exhibited significant fluctuations. Specifically, the diversity decreased significantly during induction chemotherapy, further declined during the neutropenic phase (P < 0.05, compared to baseline), and gradually recovered during the recovery phase, though not fully returning to baseline levels.The abundances of beneficial bacteria, such as Firmicutes and Bacteroidetes, gradually decreased during chemotherapy, whereas the abundances of opportunistic pathogens, including Enterococcus, Klebsiella, and Escherichia coli, progressively increased.Analysis of the dynamic changes in gut microbiota of seven patients with bloodstream infections revealed that the bloodstream infection pathogens could be detected in the gut microbiota of the corresponding patients, with their abundance gradually increasing during the course of infection. This finding suggests that bloodstream infections may be associated with opportunistic pathogens originating from the gut microbiota.Compared to non-infected patients, the baseline samples of infected patients showed a significantly lower relative abundance of Bacteroidetes (P < 0.05). Regression analysis indicated that Bacteroidetes abundance is an independent predictive factor for infectious complications (P < 0.05, OR =13.143). CONCLUSION During induction chemotherapy in AML patients, gut microbiota α-diversity fluctuates significantly, and the abundance of opportunistic pathogens increase, which may be associated with bloodstream infections. Patients with lower baseline Bacteroidetes abundance are more prone to infections, and its abundance can serve as an independent predictor of infectious complications.

Objective:To understand the uptake of post-exposure prophylaxis (PEP) and related factors among male sex workers (MSW) and provide references for the promotion of PEP.Methods:A cross-sectional study was conducted using convenience sampling to recruit MSW participants with the help of a community-based organization in October 2023, in Wuxi City, Jiangsu Province. The sample size was estimated at 340 people. A self-administered questionnaire was used to collect their social demographic characteristics, sexual behaviors, knowledge, beliefs, and uptake of PEP. A logistic regression model was used to analyze factors associated with the uptake of PEP in MSW. The SPSS 26.0 software was used for statistical analysis.Results:A total of 357 participants were recruited, mainly aged 18-20 (55.7%,199/357), unmarried (94.4%,337/357), and having an education background of junior high school or below (50.1%,179/357). Among 357 participants, 64.4% (230/357) knew about PEP, 51.0% (182/357) believed in the efficacy of PEP, and 13.4% (48/357) had experience of using PEP. Among 68 respondents having high-risk sexual behaviors in the past 3 months, 17.6% (12/68) have had uptake of PEP. Multivariable logistic regression analysis showed that group sex with men in the past 3 months (a OR=7.51, 95% CI: 1.37-41.09), HIV testing in the past 3 months (a OR=2.89, 95% CI: 1.16-7.16), the experience of using pre-exposure prophylaxis (a OR=30.18,95% CI: 12.60-72.24) and believing in the efficacy of PEP (a OR=2.94, 95% CI: 1.04-8.29) were the associated factors with the uptake of PEP in MSW. Conclusions:Although the overall uptake rate of PEP in MSW was high, the proportion of using PEP was still low among participants having high-risk sexual behaviors in the past 3 months. Therefore, it is necessary to strengthen HIV risk awareness education considering their characteristics and promote timely uptake of PEP to interrupt HIV transmission.

Anthropometric indexes play a crucial role in identifying obesity. However, as an internationally commonly used indicator of obesity diagnosis, BMI has limitations in distinguishing lean body mass from fat mass. The weight-adjusted waist index (WWI), a novel anthropometric index, assesses adiposity through standardized waist circumference for weight, which presents an excellent capacity to predict the morbidity and mortality risks of various diseases. However, research on WWI is still in the exploratory stage, and there is a lack of unified standards for using this indicator to determine obesity. In addition, its potential application in children and adolescents also urgently needs to be explored. Therefore, this article comprehensively summarizes and compares the distinctive characteristics between WWI and other obesity-related anthropometric indexes. Bibliometric methods are used to analyze the hotspots and trends of WWI-related research, and we focus on discussing the value of WWI in predicting adverse health outcomes, including cardiovascular disease, diabetes, liver and kidney diseases. We aim to promote the application of WWI in a broader field and fully demonstrate its important public health significance and broad application prospects.

Objective To compare and analyze the application value of domestic Octoparms and imported Celect inferior vena cava filter(IVCF)in the interventional treatment of venous thromboembolism(VTE).Methods Forty patients with VTE were randomly divided into Octoparms group(experimental group)and Celect group(control group)according to the double-blinded method of the central random system.All the patients underwent filter placement,catheter-directed thrombolysis and filter retrieval.The primary end point was the success of filter placement and retrieval,and the secondary end point included indwelling complications such as the occurrence of pulmonary embolism(PE)and filter tilt and migration.Results Forty patients were enrolled in this study,22 patients and 18 patients were divided into the experimental group and the control group,respectively.Among them,11 cases were identified with right lower extremity deep vein thrombosis,29 cases with left lower extremity deep vein thrombosis,17 cases with PE,and 6 cases with inferior vena cava thrombosis.The success rate of IVCF placement was 100%in all participants.Immediately after filter place-ment,the angle of filter tilt was(3.8±2.3)° in the experimental group and(4.9±2.8)° in the control group(t=1.44,P=0.16).Filter retrieval was successful in 21 cases(21/22,95.5%)of the experimental group and 17 cases(17/18,95.5%)of the control group.There was no significant difference between the two groups(t=0.14,P=0.89).The mean indwelling time of filter was(8.0±2.1)days in the experimental group and(9.7±3.1)days in the control group(t=0.73,P=0.47).The angle of filter tilt was(5.3±3.4)° in the experimental group and(5.7±7.7)° in the control group(t=0.19,P=0.85).There was no significant difference for filter placement and retrieval between the two groups(t=0.48 and 2.00,P=0.06 and 0.64,respectively).There were no complications of filter migration,strut penetration or new PE in both groups.Conclusion The application value of domestic Octoparms and impor-ted Celect IVCF is similar in interventional treatment of VTE.

Objective:To evaluate the effect of nursing specialist nurses′ assistance on the ability of nursing home nurses to maintain venous catheter under the vision of combination of medical care and nursing care, providing reference for carrying out specialized nursing assistance work in grassroots hospitals.Methods:This study was an experimental study. According to Miller′s pyramid theory, a model of specialist nurse assistance was established with specialized technology as the core. From January to December 2021, three nursing hospitals in Suzhou were assisted. Convenience sampling method was used to investigate the ability of intravenous catheter maintenance, the incidence of central venous catheter maintenance defects, the incidence of central venous catheter complications and unplanned extubation, and the satisfaction of doctors and patients before and after help.Results:Totally 86 nurses were included, aged (33.17 ± 2.31) years old. After the help, the theoretical and operational skill scores of nurses in the nursing home were (89.77 ± 2.11) and (92.75 ± 1.62) points, respectively, which were significantly higher than those before the help (60.84 ± 2.71) and (79.81 ± 1.68) points, and the differences were statistically significant ( t=-84.96, -52.12, both P<0.05). Among the maintenance defects of central venous catheter in nursing homes, incomplete labeling, film wrapping, blood seepage, catheter discounting, non-standard film fixing, and incomplete information of extended care were 9.95% (21/211), 8.53% (18/211), 2.84% (6/211), 6.16% (13/211), 4.74% (10/211), 2.37% (5/211) after help, all lower than 50.57% (89/176), 43.18% (76/176), 14.20% (25/176), 25.57% (45/176), 18.18% (32/176), 11.93% (21/176) before help. The differences were statistically significant ( χ2 values were 14.00 to 77.81, all P<0.05). The incidence of medical adhesive related skin injury, catheter obstruction complications and unplanned extubation were 4.44% (4/90), 3.33% (3/90) and 2.22% (2/90), respectively, which were lower than 20.51% (16/78), 15.38% (12/78) and 11.54% (9/78) before help. The differences were statistically significant ( χ2=8.81, 6.06, 4.50, all P<0.05). Doctors′ satisfaction with nurses and patients′ satisfaction with nursing work were 96.43%(27/28) and 93.75%(45/48), respectively, both higher than 71.43%(20/28) and 72.73%(32/44) before help, and the differences were statistically significant respectively ( χ2=4.77, 5.97, both P<0.05). Conclusions:From the perspective of combination of medical care and nursing care, the maintenance and assistance of intravenous catheters by the team of intravenous therapy nurses in nursing hospitals can effectively reduce the incidence of central venous catheter complications and unplanned extubation, improve the maintenance ability of intravenous catheters of nurses in nursing hospitals, and help to improve the quality of nursing care in nursing hospitals.
