Objective:To explore the mediating role of dietary health beliefs in the relationship between family functioning and the frequency of sugar-containing food intake among adolescents with dental caries, in order to clarify the underlying mechanism through which dietary health beliefs influence caries-related dietary behaviors via family factors.Methods:Using convenience sampling method, we selected adolescents patients diagnosed with dental caries and their parents who visited the Affiliated Stomatological Hospital of Nanjing Medical University from July to September 2023 as the research subjects. Conducted a cross-sectional survey using a general information questionnaire, Family Functioning Scale, Adolescent Dietary Health Belief Scale, and Sugar-Sweetened Diet Intake Frequency Scale. Mediation analysis was conducted.Results:A total of 475 questionnaires were distributed, and 460 valid responses were obtained, yielding a valid response rate of 96.84%. Among the 460 adolescent patients, 306 were female and 154 were male, with a mean age of (13.42 ± 1.17) years old. The mother's age was (40.28 ± 4.24) years old, and the father's age was (42.12 ± 4.48) years old. The score for the frequency of sugar-containing food intake was 15.95 ± 5.34, the dietary health belief score was 75.57 ± 18.62, and the family functioning score was 174.24 ± 25.39. Family functioning was positively correlated with dietary health beliefs ( r = 0.428, P<0.05), and negatively correlated with the frequency of sugar-containing food intake ( r = -0.225, P<0.05). Dietary health beliefs were negatively correlated with the frequency of sugar-containing food intake ( r = -0.332, P<0.05). The mediating effect of dietary health beliefs on the relationship between family functioning and sugar-containing food intake frequency was -0.332, accounting for 43.92% of the total effect. Conclusions:Dietary health beliefs play a partial mediating role between family function and the frequency of sugary diet intake. It is suggested that family function construction should be strengthened to improve adolescents' health beliefs and reduce the incidence of dental caries.

Objective:To assess the effectiveness of a 6-month Ba Duan Jin exercise program in improving the balance of community-dwelling older adults.Methods:A two arms, parallel-group, cluster randomized controlled trial was conducted in 1 028 community residents aged 60-80 years in 40 communities in 5 provinces of China. Participants in the intervention group (20 communities, 523 people) received Ba Duan Jin exercise 5 days/week, 1 hour/day for 6 months, and three times of falls prevention health education, and the control group (20 communities, 505 people) received falls prevention health education same as the intervention group. The Berg balance scale (BBS) score was the leading outcome indicator, and the secondary outcome indicators included the length of time of standing on one foot (with eyes open and closed), standing in a tandem stance (with eyes open and closed), the closed circle test, and the timed up to test.Results:A total of 1 028 participants were included in the final analysis, including 731 women (71.11%) and 297 men (28.89%), and the age was (69.87±5.67) years. After the 3-month intervention, compared with the baseline data, the BBS score of the intervention group was significantly higher than the control group by 3.05 (95% CI: 2.23-3.88) points ( P<0.001). After the 6-month intervention, compared with the baseline data, the BBS score of the intervention group was significantly higher than the control group by 4.70 (95% CI: 4.03-5.37) points ( P<0.001). Ba Duan Jin showed significant improvement ( P<0.05) in all secondary outcomes after 6 months of exercise in the intervention group compared with the control group. Conclusions:This study showed that Ba Duan Jin exercise can improve balance in community-dwelling older adults aged 60-80. The longer the exercise time, the better the improvement.

Prone position ventilation(PPV)is a lung protective ventilation strategy widely used in patients with acute respiratory distress syndrome(ARDS)to improve ventilation and oxygenation of the lungs by changing the patient's position.During PPV treatment,patients may face a variety of complications and risks,such as pressure injury,brachial plexus injury,corneal injury and unplanned extubation,which aggravate the patient's pain,increase medical costs and affect the prognosis of the disease.To this end,medical staff at Zhongda Hospital Southeast University jointly designed a PPV patient care kit pillow and obtained a National Utility Model Patent of China(patent number:ZL 202221128961.7).The PPV patient care kit pillow is composed of head pad,chest pad,hip pad and lower limb pad,with gel on its surface,which can reduce friction force and shear force;grooves are set on the middle of head pad,two sides above chest pad,middle of chest pad,middle of hip pad and lower limb pad,which can effectively avoid compression of corresponding parts and reduce the risk of pressure injury;and air bags are set on both sides below head pad,hip pad and lower limb pad,which can be inflated unilaterally or bilaterally at the same time and used for deflecting or elevating the body;in addition,a tube limiting groove is set on the outside of head pad,which can effectively fix the tracheal tube and reduce the risk of tube displacement and unplanned extubation.The overall structure of the pillow of this PPV patient care kit conforms to the angle of human mechanics and has strong versatility,which can improve the comfort,safety and effectiveness of PPV therapy for patients and reduce the work burden of medical staff,and has good application value.

Objective: Depression was common during coronavirus disease-2019 (COVID-19) pandemic, while the association of perceived stress with depression among vaccinated healthcare workers has not been investigated. This study aimed to address this issue. Methods: We included a total of 898 fully vaccinated healthcare workers during the outbreak of severe acute respiratory syndrome coronavirus 2 Delta variant in Nanjing, 2021. Depression was ascertained by Patient Health Questionnaire-9, with a cut-off score of ≥5 indicative of mild-to-severe depression. Perceived stress, resilience, and compassion fatigue were assessed by Perceived Stress Scale-10, Resilience Scale-25, and Professional Quality of Life Scale version-5, respectively. Logistic regression analyses were used to estimate the odds ratio (OR) and 95% confidence interval (CI), along with subgroup and mediation analyses. Results: The prevalence of mild-to-severe depression was 41.1% in vaccinated healthcare workers. The odd of mild-to-severe depression was increased with higher perceived stress. Compared with vaccinated healthcare workers with the lowest tertile of perceived stress, those with the highest tertile had increased odds of mild-to-severe depression by 120% (OR 2.20, 95% CI 1.46 to 3.31) after multivariable-adjustment. However, perceived stress was not associated with mild-to-severe depression in vaccinated healthcare workers with strong resilience, but was in those with weak resilience (pinteraction=0.004). Further analysis showed that compassion fatigue mediated the relationship between perceived stress and mild-to-severe depression, with a mediating effect of 49.7%. Conclusion Perceived stress was related to an increased odd of mild-to-severe depression in vaccinated healthcare workers during COVID-19 pandemic, and this relationship might be explained by compassion fatigue.

Chronic heart failure is a serious stage of various cardiovascular diseases.It has the characteristics of high morbidity, high fatality rate, and high rehospitalization rate, which leads to a decrease in the quality of life of patients.The theory of health ecology points out that the factors affecting individual health are multi-level. The theory uses systematic indicators to evaluate the prognosis of patients with chronic heart failure and scientifically analyze the complex factors behind the disease which can provide patients with professionalism, standardization and individualized high-quality medical resources and provide a reference for effectively improving the quality of life.

A standardized training evaluation system for novice nurses based on Mini-CEX was established which includes 8 first-level dimensions and 66 subclauses. Conclusions The standardized training evaluation system for novice nurses based on Mini-CEX built through Delphi expert consultation is scientific and reliable, and can provide evidence for the evaluation method of standardized training for novice nurses in China.

Objective? To investigate the correlation between post traumatic growth, social support and resilience in patients with breast cancer, and to provide reference for intervention programme on enhancing positive psychological quality. Methods? Totally 180 patients with breast cancer from 4 ClassⅢ Grade A hospitals in Jiangsu Province were selected by convenience sampling method from June to October in 2018. They were investigated with General Information Questionnaire, Post Traumatic Growth Inventory (PTGI), Social Support Rating Scale (SSRS), and Connor-Davidson Resilience Scale (CD-RISC). Results? In breast cancer patients, the total scores of PTGI, SSRS and CD-RISC were (62.52±17.59), (35.15±9.29) and (56.51±18.33) scores. Correlation analysis showed that the total scores of PTGI and its each dimension were positively correlated with the total scores of SSRS, as well as the total scores of CD-RISC and its each dimension (P＜0.01); the total scores of SSRS and its each dimension were positively correlated with the total scores of CD-RISC and its each dimension (P＜ 0.01). Multivariate linear regression analysis showed that resilience, methods of disease detection, and treatment plans were independent influencing factors of PTG in patients with breast cancer. Both social support and resilience could positively predict PTG, whose path coefficients were 0.493 and 0.302, respectively. Resilience was a mediator of social support and PTG. The indirect effect was 0.080. Conclusions? Resilience plays an important role in mediating between social support and PTG in patients with breast cancer. The resilience training could promote patients' PTG ability .
