Background: A decline in adolescent health holds significant repercussions for public health. Promoting exercise is essential to improve physical and mental health among youth. This study aimed to explore the effect of CrossFit training programs on the physical health and sociogenic somatic anxiety of adolescents. Methods: In March 2023, 100 adolescents were openly recruited from eight middle schools in Jinhua, China. The participants, were divided equally into control and experimental groups, experienced either traditional or CrossFit training, respectively, over nine weeks. Evaluation measures included the analysis of social physique anxiety, body esteem, physical self-efficacy, and general physical health before and after the exercise program. Results: Post-intervention data demonstrated marked reductions across all facets of the social physique anxiety scale, including worries about public scrutiny, anxiety from social comparison, and discomfort related to one’s physical self-image, more so in the experimental group (P<0.05). Likewise, assessments of the physical self-perception profile and physical self-efficacy scale were enhanced, again with the experimental cohort displaying more pronounced improvements (P<0.05). Results from biophysical function evaluations indicated significant health improvements post-intervention, with noted advancements in lung capacity, aerobic fitness by the standing long jump, and muscular endurance as assessed by grip strength, sit-up, and push-up counts, primarily in the experimental group (P<0.05). Conclusion: CrossFit training offered considerable advantages by reducing social physique anxiety and enhancing adolescents’ body esteem and physical self-efficacy. The program stimulated improvements in body composition, cardiorespiratory fitness, muscle strength, and flexibility.

Background: Cesarean section (CS) is one of the most important pregnancy concerns in the world. Increased inflammation is associated with increased risk factors for cesarean section. Diet plays a major role in reducing inflammation. This study aimed to investigate the relationship between dietary inflammatory index (DII) and the risk of Cesarean section in Tehranian women. Methods: This case-control study included 390 pregnant women in Tehran, Iran between 2020 and 2021 at their initial visit to pregnancy clinics, selected by a cluster sampling method. Dietary intakes were determined using valid reliable questionnaires and DII was calculated. Weight, height, and waist circumference were also measured. Results: The mean age of the subjects was 28.5 yr (± 5.02) and weight, body mass index (BMI) and waist circumference (WC) in the case group with a higher DII were higher. Odds ratio (OR) of cesarean section in DII quartiles was statistically significant. Confounding factors including age, BMI and total energy intake were adjusted in the first model and weight, waist circumference, physical activity and supplements in the second model and the relationship remained significant (P<0.001). Conclusion: High scores of dietary inflammatory index, possibly through an increase in inflammatory factors, can increase the chances of having a cesarean section.

Background: Asthma and allergic diseases are common chronic non-communicable conditions that can negatively impact the quality of life of patients. Psychological factors play a role in both the onset and progression of these conditions. The purpose of this study was to examine the relationship between handedness and emotion regulation and cognitive emotion regulation strategies in patients with asthma and allergies in Isfahan, central Iran. Methods: We employed a causal-comparative research design. The study population consisted of all patients visiting Asthma and Allergy Clinic in Isfahan. One hundred participants were selected through probability sampling. Data were collected using the Emotion Regulation Questionnaire and the Cognitive Emotion Regulation Strategies Questionnaire, and were analyzed using univariate analysis of variance (ANOVA). Results: Cognitive emotion regulation was significantly different between right-handed and left-handed patients with asthma and allergies (P=0.0001). A significant difference was also observed between the two groups in their emotion regulation strategies (P=0.031). The rate of positive and negative cognitive regulation strategies was higher in left-handed individuals with asthma and allergies, compared to right-handed individuals. Conclusion: Overall, handedness has a significant impact on the behavior and mental health of patients suffering from asthma and allergies. Therefore, handedness should be taken into consideration in interventions for emotion regulation.

Background: Neck circumference (NC) measurement has been recently developed as a simple and time-saving anthropometric method for predicting cardiovascular risk. Asymptomatic hyperuricemia is known as one of the cardiovascular risk factors. This study investigated the association between NC and asymptomatic hyperuricemia among the general population of Korea. Methods: This cross-sectional study examined data from 7,629 participants in the 2019–2020 Korea National Health and Nutrition Examination Survey. Multivariable logistic regression analysis was used to identify the factors associated with hyperuricemia. Results: Approximately 10% of participants corresponded to hyperuricemia group who were likely to be male, have more comorbidities, poorer habits, and larger NC. Multivariable regression analysis revealed that NC was significantly associated with hyperuricemia in women (OR 1.17; 95% CI 1.06-1.30), but not in men (OR 1.04; 95% CI 0.96-1.12). Conclusion: A large NC is independently correlated with hyperuricemia among Korean women.
背景：颈围（NC）测量是最近发展起来的一种预测心血管风险的简单、省时的人体测量方法。众所周知，无症状高尿酸血症是心血管风险因素之一。本研究调查了韩国普通人群中颈围与无症状高尿酸血症之间的关系。研究方法这项横断面研究研究了 2019-2020 年韩国国民健康与营养调查中 7629 名参与者的数据。采用多变量逻辑回归分析来确定与高尿酸血症相关的因素。结果显示约10%的参与者属于高尿酸血症组，他们可能是男性、合并症较多、生活习惯较差和NC较大。多变量回归分析显示，女性的 NC 与高尿酸血症有显著相关性（OR 1.17；95% CI 1.06-1.30），但男性的 NC 与高尿酸血症无显著相关性（OR 1.04；95% CI 0.96-1.12）。结论在韩国女性中，NC过大与高尿酸血症有独立的相关性。

Background: We analyzed the effects of psychological capital on organizational commitment and turnover intention among flight attendants at a Korean airline and the mediating effect of organizational commitment. Methods: Data were collected through a 2022 survey of Korean flight attendants, yielding 297 responses. Model reliability and validity were assessed to confirm hypotheses. Results: Hope had a significant negative effect on turnover intention P<0.05), whereas optimism and resilience did not have significant effects on turnover intention. Additionally, hope had a significant positive effect on normative and continuance commitment, unlike optimism and resilience, which did not have significant effects on normative commitment or continuance commitment. Both normative commitment and continuance commitment negatively influenced turnover intention. Organizational commitment mediated the relationship between psychological capital and turnover intention, reinforcing the positive impact of psychological capital on reducing turnover intention. Conclusion: This study underscores the significance of psychological capital in shaping organizational commitment and reducing turnover intention among Korean flight attendants. Strengthening psychological capital and fostering organizational commitment can bolster airline stability, competitiveness, and service quality.

Background: The increasing accumulation of plastic waste is the most serious threat to the marine ecosystem. People who still have the habit of disposing of solid waste, especially plastic-type waste, in the marine environment have led to the discovery of microplastic content in various marine biota such as fish and shellfish. We aimed to assess the environmental health risks of microplastics due to consumption of marine life in the coastal area. Methods: We used an observational method with the Environmental Health Risk Assessment (EHRA) design to analyze the health risks of humans consuming fish and shellfish containing microplastics. This research was conducted in the coastal area of Takalar Regency, Indonesia in 2022. The samples used consisted of human (n = 30) and marine biota (fish, n=20; shellfish, n=20) samples. The data were obtained from observations, physical measurements of biota, laboratory tests, polymer type identification by Fourier Transform Infrared (FTIR) spectroscopy, and microscopy. Results: The average concentration of microplastics containing styrene compounds in shellfish was 2.01 mg/kg. The abundance of MPs in the fish and shellfish samples was 0.01 particles/g or 10 particles/kg in fish and 7 particles/individual in shellfish. The MPs were found in line, fragment, film, and pellet forms, with different size and color variations. The average MPs exposure risk level (RQ value) for both fish and shellfish was 0.02. Conclusion: All samples had RQ values < 1, which means that the microplastic-containing tofu shellfish were still safe for consumption by people living in the Takalar coastal area.

Background: Diabetes mellitus (DM) has different prevalence by region. This study aimed to identify the differences in the effects of obesity and depression on DM in South Korean adults by region. Methods: The participants were 14,343 adults (≥30 yr) from Ulsan (regions with the lowest prevalence of DM) and Jeonbuk (regions with the highest prevalence of DM), and data were extracted from the Community Health Survey 2019. We applied a complex sampling design analysis to reflect the stratified, clustering and weights. The data were analyzed using the unweighted frequencies, weighted percentage, mean, standard error, Chi-Square test and multiple logistic regression analysis (SPSS 25.0). Results: Regarding the main result for Ulsan, the odds ratio of DM increased by 1.94, 2.52,1.57, and 4.87 times for obesity(25-29.9kg/m²), high obesity(≥30kg/m²), depression, and receipt of psychological counseling for depression, respectively. In Jeonbuk, the odds ratio of DM increased by 1.79, 2.84, and 3.59 times for obesity, high obesity, and unmet medical experience, respectively. On the other hand, depression-related variables were found to not influence DM Conclusion: We provided the rationale for conducting a health project that interventions for obesity and depression should be included in DM management programs differently in Ulsan and Jeonbuk regions

Background: Occupational hearing loss of workers exposed to impulse noise and workers exposed to steady noise for a long time may have different clinical characteristics. Methods: As of May 2019, all 92 servicemen working in a weapon experimental field exposed to impulse noise for over 1 year were collected as the impulse noise group. As of Dec 2019, all 78 servicemen working in an engine working experimental field exposed to steady noise for over 1 year were collected as the steady noise group. The propensity score matching (PSM) model was used to eliminate the imbalance of age and working time between the two groups of subjects. After propensity score matching, 51 subjects in each group were finally included in the study. The machine learning model is constructed according to pure tone auditory threshold, and the performance of the machine learning model is evaluated by accuracy, sensitivity, specificity, and AUC. Results: Subjects in the impulse noise group and the steady noise group had significant hearing loss at high frequencies. The hearing of the steady noise group was worse than that of the impulse noise group at speech frequency especially at the frequency of 1 kHz. Among machine learning models, XGBoost has the best prediction and classification performance. Conclusion: The pure tone auditory threshold of subjects in both groups decreased and at high frequency. The hearing of the steady noise group at 1 kHz was significantly worse than that of the impulse noise group. XGBoost is the best model to predict the classification of our two groups. Our research can guide the prevention of damage caused by different types of noises.

Methods: A total of 300 diabetic patients and essential hypertension admitted to the Second Affiliated Hospital of Dalian Medical University, Dalian, China from January 2021 to December 2022 were selected. They were divided into an observation group and a control group using a random number table method. The control group was treated with conventional antihypertensive drugs, hypoglycemic drugs, and lipid-lowering drugs. The observation group was supplemented with liraglutide based on the control group. Blood pressure, blood glucose and blood lipid of the two groups were compared at the initial stage of medication and after 4 weeks and half a year, and the influencing factors of patients with persistent hypertension were further analyzed through Logistic regression. Results: After 4 weeks and 6 months of medication, inter group comparisons showed that systolic blood pressure (SBP), diastolic blood pressure (DBP), fasting blood glucose (FBG) and glycated hemoglobin (HbA1c), as well as total cholesterol (TC), triacylglycerol (TG), and plasma arteriosclerosis index (AIP) in the observation group were significantly lower than those in the control group (Ρ<0.05). Multivariate Logistic regression model analysis showed that age, smoking history, drinking history, taking conventional antihypertensive drugs, taking hypoglycemic drugs, taking lipid-lowering drugs, BMI, FBG, HbA1c and LDL-C were independent influencing factors for persistent hypertension (Ρ<0.05). Conclusion: GLP-1RAs could effectively improve the indexes including blood pressure, blood glucose and blood lipid in diabetic patients with hypertension.

Background: We aimed to evaluate the performance of the current algorithm the HIV diagnosis that has been performed for four years. Results of HIV Ag/Ab tests, anti-HIV 1/2 confirmatory tests, HIV-1 RNA tests and the time for official results to be approved were evaluated. Methods: The relationship of HIV Ag/Ab tests, anti-HIV 1/2 confirmation tests and HIV-1 RNA PCR tests, their result times and suitability to the algorithm were examined at Izmir Dokuz Eylül University between May 2017 and June 2021. Results: HIV Ag/Ab ELISA was reactive repetitively in 165/54628 (0.30%) serum samples. Anti-HIV 1/2 confir-mation test was reactive in 54.42% (80/147) of samples. The most common pattern (18.2%) in the con-firmation tests was the positivity of the antibodies against gp160 - gp41 envelope glycoproteins together. The mean reporting time of the confirmation test result was 3h 50 min after the ELISA test. The mean reporting time of the HIV-1 RNA PCR was 12.79 d (±10.22) after the ELISA test and 12.63 (± 10.12) day after the confirmation test. In ROC analysis, the estimated rate of the ELISA test for the confirmation test was highest when S/CO was >13.16 (sensitivity: 97.59 %, specificity: 97.59%). Conclusion: The confirmation test in the current algorithm enabled the rapid test results, early diagnosis of HIV and early antiretroviral therapy. To use the new algorithm effectively, decentralization of the validation tests would be appropriate.
背景：我们的目的是评估已实施四年的现行艾滋病诊断算法的性能。我们对 HIV Ag/Ab 检测结果、抗 HIV 1/2 确证检测结果、HIV-1 RNA 检测结果以及正式结果获得批准的时间进行了评估。方法在 2017 年 5 月至 2021 年 6 月期间，在伊兹密尔 Dokuz Eylül 大学对 HIV Ag/Ab 检测、抗 HIV 1/2 确认检测和 HIV-1 RNA PCR 检测的关系、结果时间和算法的适用性进行了研究。结果显示在 165/54628 份（0.30%）血清样本中，HIV Ag/Ab ELISA 呈重复反应。54.42% （80/147）的样本中，抗 HIV 1/2confir-mation检测呈反应性。确证试验中最常见的模式（18.2%）是 gp160 - gp41 包膜糖蛋白抗体同时阳性。确认检测结果的平均报告时间为 ELISA 检测后 3 小时 50 分钟。HIV-1 RNA PCR 的平均报告时间为 ELISA 检测后 12.79 天（±10.22）和确认检测后 12.63 天（±10.12）。在 ROC 分析中，当 S/CO >13.16 时，ELISA 检测用于确认检测的估计比率最高（灵敏度：97.59%，特异性：97.59%）。结论现行算法中的确证试验能够快速得出检测结果，及早诊断出艾滋病病毒，并及早进行抗逆转录病毒治疗。为有效使用新算法，应分散进行确认检验。
