Effect of artificial natural light on the development of myopia among primary school-age children in China:a three-year longitudinal study

AIM:To assess the efficacy of artificial natural light in preventing incident myopia in primary school-age children.METHODS:This is a prospective,randomized control,intervention study.A total of 1840 students from 39 classes in 4 primary schools in Foshan participated in this study.The whole randomization method was adopted to include classes as a group according to 1:1 randomized control.Classrooms in the control group were illuminated by usual light,and classrooms in the intervention group were illuminated by artificial natural light.All students received uncorrected visual acuity and best-corrected visual acuity measurement,non-cycloplegic autorefraction,ocular biometric examination,slit lamp and strabismus examination.Three-year follow-up,the students underwent same procedures.Myopia was defined as spherical equivalent refraction≤-0.50 D and uncorrected visual acuity<20/20.RESULTS:There were 894 students in the control group and 946 students in the intervention group with a mean±SD age of 7.50±0.53y.The three-year cumulative incidence rate of myopia was 26.4%(207 incident cases among 784 eligible participants at baseline)in the control group and 21.2%(164 incident cases among 774 eligible participants at baseline)in the intervention group[difference of 5.2%(95%CI,3.7%to 10.1%);P=0.035].There was also a significant difference in the three-year change in spherical equivalent refraction for the control group(-0.81 D)compared with the intervention group[-0.63 D;difference of 0.18 D(95%CI,0.08 to 0.28 D);P<0.001].Elongation of axial length was significantly different between in the control group(0.77 mm)and the intervention group[0.72 mm;difference of 0.05 mm(95%CI,0.01 to 0.09 mm);P=0.003].CONCLUSION:Artificial natural light in the classroom of primary schools can result in reducing incidence rate of myopia during a period of three years.

Factors Associated with HPV Vaccine Uptake among Girls Aged 9 - 14 in the Langue de Barbarie Area of Saint-Louis, Senegal in 2024

Introduction: The HPV vaccine was included in the Expanded Programme on Immunisation in Senegal in 2018. However, vaccination coverage is still low among targeted girls. The aim of this research was to study the factors associated with vaccine uptake among girls aged 9 - 14 years in the Langue de Barbarie area of Saint-Louis, Senegal. Methodology: This was a descriptive and analytical cross-sectional study. The sample size was calculated using the Schwartz formula and distributed proportionally to the size of the population in the neighborhoods. Data were collected from 2nd to 19th January 2024 from mothers or guardians of girls aged 9 to 14 using anonymous questionnaires configured on tablets with Survey 123 software and analysed using R software. Results: A total of 799 people were interviewed. The average age of the respondents was 35.67 years, with a standard deviation of 7.08 and a range of 17 and 49 years. Reported vaccination coverage was 41.9%. Factors positively correlated with vaccination included: attendance at primary school or daara (OR = 2.50 [CI: 1.43 - 4.48] and OR = 2.05 [CI: 1.09 - 3.94]), information about vaccination (OR = 6.64 [CI: 4.59 - 9.72]), history of cervical cancer screening among mothers or guardians (OR = 6.64 [CI: 4.59 - 9.72]). Conclusion: Identifying the factors associated with HPV vaccination is necessary to assess and improve the vaccination strategy in order to improve vaccination coverage among targeted girls.

Study on the Knowledge of Mothers or Guardians of Girls Aged 9 - 14 from the Langue de Barbarie in Saint-Louis, Senegal about Cervical Cancer and Its Relationship to HPV Vaccination in 2024

Introduction: The relationship between knowledge of HPV and vaccination has been established. The aim of this study was to investigate the knowledge of mothers or guardians of girls aged 9 - 14 about cervical cancer and their attitudes to HPV vaccination. Methodology: This was a descriptive cross-sectional survey. The sample size was calculated using the Schwartz formula and distributed proportionally to the size of the neighbourhood population. Data was collected between 2nd to 19th January 2024 using anonymous questionnaires configured on tablets with Survey 123 software and analysed using R software. Results: A total of 799 people were interviewed. The average age of the respondents was 35.67 years, with a standard deviation of 7.08 and a range of 17 and 49 years. The information channels for cervical cancer were the media (82.8%), health facilities (47.7%) and community intermediaries (23.3%). Only 53.7% had information about the vaccine and 25.5% about the vaccination strategy. The main reason for accepting the vaccine was awareness of the seriousness of cervical cancer (55.1%). Conclusion: It is essential to take stock of knowledge about cervical cancer and attitudes to vaccination to assess the impact of interventions and redirect strategies to improve vaccination coverage. .

Gaze and Oppositional Gaze in Mr. Tang’s Girls

The gaze is a means of power that can flow through family relationships.It has intense regulatory overtones.In her short story Mr.Tang’s Girls,Malaysian-Chinese Anglophone diasporic writer Shirley Geok-lin Lim shows the conflict between Eastern and Western cultures and the resistance of women under the oppression of patriarchy through the portrayal of the father,Ah Kong,and the eldest daughter,Kim Li.Based on Foucault’s discipline gaze and Hooks’oppositional gaze,this article analyzes the power operation in the story from the following three aspects:the male gaze,discipline and self-discipline,and the oppositional gaze.Kim Li’s subjective image of breaking free from male ownership control has been presented.It suggests the difficulties encountered by female groups in their rebellion against the male gaze and their pursuit of freedom and emancipation.It also reflects the tragedy of awakening women’s destinies under the dual oppression of patriarchy and the East-Westen cultural conflict.

Research Progress in Integrated Chinese and Western Medicine Health Management for School-Age Children with Asthma

Objective:The purpose of this study is to investigate the application of Chinese and Western medicine in the health management of school-age children with asthma and its research progress,with a view to providing a more comprehensive and effective management strategy for the clinic.Methods:Using the method of literature review,this study systematically searched and analyzed the relevant studies on the combination of Chinese and Western medicine in the health management of school-aged children with asthma in recent years,focusing on Chinese medicine treatment,Western medicine treatment,and the combined health management of Chinese and Western medicine.Results:Chinese medicine treatment,Western medicine treatment,and the health management mode of combining Chinese and Western medicine showed unique advantages in school-age asthmatic children.Through the comprehensive use of Chinese medicine’s diagnosis and treatment,Chinese medicine conditioning,Chinese medicine characteristic therapy,and Western medicine’s modern medical methods,it not only effectively relieved asthma symptoms but also significantly improved the quality of life of the children.At the same time,this management mode also focuses on the psychological guidance and family care of the children,forming an all-round and multi-level health management system.Conclusion:The health management strategy of combining Chinese and Western medicine has a broad application prospect in school-age asthmatic children,and its specific interventions and mechanisms of action should be further studied to provide more scientific and systematic guidance for clinical practice.

Improving school physical education to increase physical activity and promote healthy growth of Chinese school-aged children Time for action

Throughout its more than 5000-year history, China has a long tradition of encouraging active engagement in physical and sport activities This enduring tradition, however, has been facing some major headwinds as China continues to expe- rience demographic and environmental changes related to aging, urbanization, and lifestyle shifts.

Step it up： Promoting physical activity in school-aged children and adolescents in China

In this special issue of the Journal of Sport and Health Science, a series of articles describe the results of the 2016 Physical Activity and Fitness in China--The Youth Study. The results show a relatively high prevalence of sedentary behaviors, unhealthy weight, lower fitness levels, and lower levels of engagement in physical exercise and fitness activities than antici- pated.

The Neurocognitive Assessment of HIV-Infected School-Aged Nigerian Children

Objective: Studies available on cognitive function among school-aged HIV-infected African and in particular Nigerian children are few. The purpose of the study was to assess the neurocognitive function of a group of HIV-infected schoolaged (6 - 15 years) children using the Raven’s Standard Progressive Matrices (RPM). Method: Cognitive assessments of 69 HIV positive children and 69 age- and sex-matched apparently healthy HIV negative control children were performed using the Raven’s Standard Progressive Matrices (RPM). The children were subdivided (Piaget’s developmental staging) into two sub-groups: the concrete operation stage (6 - 11 years) and the formal operation stage (12 - 15 years) for analysis. Result: The mean RPM score for the HIV positive children was 18.2 (8.0 - 47.0, SD 9.8) which was significantly lower than the score of 27.2 (8.0 - 52.0, SD 13.8) for the HIV negative children (p < 0.001). On the RPM grading and using the HIV negative children as the standard, 56.5% of the HIV positive children had cognitive performance at below average to intellectually defective range. Conclusion: School-aged HIV positive children had significantly lower cognitive scores compared with age and gender-matched HIV negative children. Routine neuropsychological evaluation of all school-aged HIV-infected children is recommended. Early detection of cognitive impairment will help in planning appropriate interventions.

Prevalence and Risk Factors Associated with Tungiasis among School-Aged Children in the City of Port Gentil, Ogooué-Maritime Province, Gabon in Central Africa

Background: Tungiasis is a skin infestation caused by the female sand flea called Tunga penetrans. Associated with a significant morbidity, this ectoparasite is present in all tropical regions, such as Gabon. Unfortunately, in this country, no study has ever been undertaken on this disease. However, in both urban and rural areas of this country, it causes disfigurement and mutilation of the feet or hands in infested persons, and is sometimes responsible for the school dropout of many children. It is in this context that this timely and relevant research was conducted to assess the prevalence and risk factors associated with Tungiasis in school-aged children in the city of Port Gentil, Ogooué-Maritime province, Gabon in Central Africa. Materials and Methods: This prospective and cross-sectional study took place from May 22 to August 18, 2022, in two popular and underprivileged neighborhoods of the city of Port Gentil. It consisted of a physical diagnosis of the participants, and with the help of a questionnaire submitted to their parents/guardians, numerous data were collected. Entered into an Excel 2016 spreadsheet, the data were exported to the R software in its R Commander interface, for two types of analyses. A univariate and a multivariate analysis, using logistic regression, first on socio-demographic characteristics and then on habitual and environmental behavioral characteristics, was performed and the variables in this analysis reported odds ratios and their 95% confidence intervals. The results were statistically significant at p Results: A total of 637 school-aged children with a mean age of 12.73 years and a standard deviation of 5.44, were registered and examined for this study. Among them, Tunga penetrans infestation was found in 242 children, indicating an overall prevalence of 37.99% (95% CI [0.34 - 0.41]). Univariate and multivariate analyses, using logistic regression, first according to socio-demographic characteristics and then according to risk factors indicated that, the age groups of 5 to 9 years (Adjusted Odds Ratio = 9.27;95% CI: [6.66 - 12. 91]) and 10 - 14 years (Adjusted Odds Ratio = 0.16;95% CI: [0.10 - 0.25]), Eshira ethnicity (Adjusted Odds Ratio = 7.46;95% CI: [2.97 - 18.76]), child’s primary education level (Adjusted Odds Ratio = 0.008;95% CI: [0.006 - 0.011]), Father’s/Guardian’s education level (Adjusted Odds Ratio = 0.22;95% CI: [0.13 - 0.35]), homemaker status (Adjusted Odds Ratio = 4.89;95% CI: [3.51 - 6. 79]) and risk factors such as: promiscuity with dogs, cats or other animals around the house (Adjusted Odds Ratio = 38.30;95% CI: [22.13 - 66.26]), wearing shoes a few times (Adjusted Odds Ratio = 0.02;95% CI [0.01 - 0.03]), walking sometimes barefoot, on land or sand (Adjusted Odds Ratio = 0.28;95% CI: [0.18 - 0.42]), having other sources of water consumed than the tap (Adjusted Odds Ratio = 0.25;95% CI: [0.16 - 037]), living in a dwelling with soil or sand (Adjusted Odds Ratio = 6.8;95% CI: [4.58 - 10.09]), having average housing conditions (Adjusted Odds Ratio = 46.8;95% CI [24.29 - 90.16]), and the number of people living in the family that was greater than or equal to 6 (Adjusted Odds Ratio = 0.1;95% CI [0.07 - 0.13]), were significantly associated with the prevalence of Tungiasis. Conclusion: The results of this study will inform control programs and water and sanitation interventions for the Tunga penetrans epidemic in Port Gentil, Gabon.

The Prevalence of Congenital Heart Disease among School-Age Children in China:A Meta-Analysis and Systematic Review

Objectives:To estimate the prevalence of Congenital Heart Disease(CHD)in school-age children,to identify the extent to which altitude affects the prevalence of the disease,and to examine trends in prevalence over time in China.Methods:Seven databases were systematically searched and last retrieved on September 10,2021 for all studies reporting the prevalence of CHD in children after 1970 in China,which were then divided into high and low altitude regions based on 2500 meters above sea level.The random-effected model was used to combine prevalence data and subgroups analysis.The baseline data of all cases and individuals were used for comparison to calculate the odds ratio(OR)for overall and different altitude prevalence.Results:A total of 12,926,083 individuals(aged 3-18 years),with 31,835 cases from 86 studies,were included in the analysis.The pooled CHD prevalence of total children was 4.69[95%confidence interval(CI):4.10 to 5.29]per 1000 children.Overall,temporal trends analysis indicated that the prevalence of CHD in children continuously decreased with time,from 6.19(95%CI:4.50 to 7.88)per 1000 children in 1976-1985 to 3.30(95%CI:2.49;4.38)per 1000 children in 2016-2021.The OR for the prevalence of CHD in children from high and low altitudes with baseline data was 2.84(95%CI:2.48 to 3.27)and 1.31(95%CI:1.13 to 1.53)(χ^(2)=53.89,p<0.01),respectively.The OR of the prevalence of CHD in male children compared to females was 0.60(95%CI:0.53 to 0.68)at high altitudes and 0.79(95%CI:0.71 to 0.89)at low altitudes.Among the seven most common subtypes,patent ductus arteriosus was the most common at high altitudes,while atrial septal defects were the most common at low altitudes.Conclusion:This study provides valuable insights for further disease prevention and etiological exploration.The overall decreasing trend in the prevalence of CHD in children over time may indicate a positive effect of perinatal management and treatment during infancy.

Persistent Congenital Paraurethral Cyst, a Rare Cause of Dysuria in a Girl

Congenital paraurethral cyst rarely occurs. Its natural history is spontaneous regression, leading to conservative management adoption. We report an exceptional case of a 13-year-old female with a persistent congenital paraurethral cyst, leading to dysuria. We surgically excised the cyst, and the outcomes were unremarkable 20 months postoperatively.

Clinical efficacy of leprerelin acetate with different dosage forms in central precocious puberty girls

Objective:To observe the clinical efficacy of different dosage forms of lepraline acetate(LA)in the treatment of girls with central precocious puberty(CPP).Methods:72 CPP girls treated in the Department of Pediatrics of Huai'an First People's Hospital from February 2021 to August 2022 were included as subjects and divided into two groups:3-month LA group(n=34)and 1-month LA group(n=38).Both group girls were treated for 6 months.Serum hormone levels,body mass index(BMI),bone age/chronological age(BA/CA)and pelvic color ultrasound were detected at 0 and 6 months after treatment,and the changes of various indexes were compared before and after treatment.Results:1)There were no significant differences in baseline data between the two groups before treatment(P>0.05).2)After 6 months of treatment,BA/CA decreased,growth rate slowed down,and predicted adult height increased in both groups(P<0.05),but there were no significant differences between groups(P>0.05).3)After 6 months of treatment,there waere no significant differences in luteinizing hormone(LH)inhibition ratio between the 3 month and 1 month dosage groups(P>0.05).After treatment,the peak value of serum LH and FSH,estradiol level,uterine volume,bilateral ovarian volume,maximum follicle diameter and the number of follicles 4mm were significantly decreased in the two groups,but there were no significant differences between the two groups(P>0.05).4)There were no significant differences in the levels of thyroid hormone,fasting blood glucose and triglyceride between the two groups before and after treatment(P>0.05).Total cholesterol levels were increased after treatment(P<0.05),but there was no significant difference between groups(P>0.05).5)No serious adverse reactions occurred during the treatment of the two dosage forms of LA,but the 3-month dosage form of LA reduced the treatment cost and improved the treatment compliance.Conclusion:The short-term efficacy of 3-month LA in the treatment of CPP in girls is similar to that of 1-month LA.The 3-month dosage form LA is a safe,effective,and economical method for the treatment of CPP in girls.
