Evaluation of teaching-in-English reform in five-year clinical tropical medicine program–Case analysis of curriculum reform of clinical medicine in Hainan Medical University

Objective: To investigate the model, quality as well as effect of teaching-in-English in five-year clinical medicine program of Hainan Medical University.Methods: The questionnaire was carried out among clinical medicine undergraduates of2012–2015 grades in Hainan Medical University, to investigate studying time, studying habits and the impact of teaching in English. Additionally results of CET-4, CET-6 and overseas internship from undergraduates of 2012–2015 grade, as well as the result of phased medical licensing examination and post-graduate entrance examination from undergraduates of 2012 were accordingly collected from the Teaching Management Department.Results: For the Chinese students in international classes, the average time of self-study was 161.49 min, 58.3% had preview before classes, and 90.7% had habit of review after classes. Thus the first time pass rate, total pass rate, first time excellent rate and total excellent rate of CET-4 and CET-6 of international classes were significantly higher than those of regular classes. The result of post-graduate entrance examination in 2016 showed that the score, pass rate and acceptance rate of international classes of 2012 grade were significantly higher those of regular classes(P < 0.01).Conclusions: Teaching-in-English reform in Hainan Medical University has achieved initial success. Chinese students from international classes are superior to those from regular classes in many aspects. However, there are still many problems, and effective measures should be implemented to promote teaching quality continuously.

Risk Factors for Geo-Helminthiasis in Children Aged 6 - 36 Months in a Rural Health District in Cameroon

Introduction and Objectives: Soil-Transmitted-Helminthiasis (STH) is a public health problem in Cameroon. The control strategies currently in place, particularly chemoprevention, has shortcomings linked to the target population, which are school-age children. The objective was to determine the prevalence and the risk factors associated with geo-helminthiasis in children aged 0 to 3 years in a rural health district. Method: From December 2020 to May 2021, a descriptive and analytical cross-sectional study of 376 children between 6 and 36 months was carried out in the Akonolinga health district. This was a cluster sampling in 4 health areas. Stool samples were collected and analysed using the mini-FLOTAC method. The results expressed as the number of eggs per gram of stool. A questionnaire on socio-demographic and lifestyle data was administered to the parents. The Chi-squared test was used to measure the association between geo-helminth infection and the data collected. A multivariate analysis using logistic regression was performed (p 0.05). Results: The prevalence of STH was 19.4% (Ascaris lumbricoides: 16% and Trichuris trichiura: 8%). Risk factors were: consumption of contaminated water (AOR = 1.93 [1.03 - 3.6];p = 0.040), early contact of the child with the ground (before age of 4 months) (AOR = 4.9 [2.1 - 11.37];p .001), habit of walking barefoot (AOR = 2.91 [1.1 - 7.97];p = 0.038), and living in a habitat with unpaved ground (AOR = 7.4 [1.55 - 35.7];p = 0.012). Conclusion: The prevalence of STHs in infants was high. Preventive chemotherapy should be extended to this age-group, and other measures intensified.

Verifying the Effects of an Education Program Leveraging Information Technology to Promote Cervical Cancer Screening in Women Aged 20 - 29—A One-Year Longitudinal Study

The purpose of this research is to implement an IT-based education program in order to promote cervical cancer screenings for women aged 20 - 29 years, as well as to examine the results of said program. This is a longitudinal/comparative study of two groups, one for which the program was implemented (the intervention group), and the other for which it was not (the control group). The program consisted of attending a health lecture and encouragement to be screened one month, six months, and one year later sent through IT-based methods. The target was unmarried women aged 20 - 29 who had neither previously given birth nor had been screened for cervical cancer in a period one year prior. They were divided into two groups, the intervention group (n = 142) and control group (n = 145). The effectiveness of the program was assessed via an initial survey and further surveys six months and one year later. Results were based on the Japanese version of the Health Belief Model Scale for Cervical Cancer and the Pap Smear Test (HBMSCCPST), knowledge scores in the categories of Healthy Lifestyles, Cervical Cancer, Cervical Cancer Screening, and screening behavior. A two-way ANOVA of the HBMSCCPST subscales and knowledge scores in the initial, six-month, and one-year surveys was performed, showing interaction in Cervical Cancer (p = 0.00). Main effects were observed in Cervical Cancer Screening (p = 0.00) and Healthy Lifestyles (p = 0.00). Regarding the amount of change from the initial survey, knowledge scores in the Cervical Cancer (p = 0.027) and Cervical Cancer Screening (p = 0.016) categories were significantly higher in the intervention group than in the control group. There was no significant difference in cervical cancer screening rates (p = 0.26) between the two groups. However, a small-degree effect size was observed for Benefits, Seriousness, and Susceptibility subscales in both examinees and non-examinees. Although the educational program of this study was effective in improving the knowledge of women in their twenties, there was little improvement in HBMSCCPST and it did not lead to the promotion of cervical cancer screening. In order to raise interest in cervical cancer screening, it is necessary to consider useful content to guide women to consult with healthcare professionals, a long-term population approach, and organizational structure of consultation.

Pivotal role of long non-coding ribonucleic acid-X-inactive specific transcript in regulating immune checkpoint programmed death ligand 1 through a shared pathway between miR-194-5p and miR-155-5p in hepatocellular carcinoma

BACKGROUND Anti-programmed death therapy has thrust immunotherapy into the spotlight.However,such therapy has a modest response in hepatocellular carcinoma(HCC).Epigenetic immunomodulation is a suggestive combinatorial therapy with immune checkpoint blockade.Non-coding ribonucleic acid(ncRNA)driven regulation is a major mechanism of epigenetic modulation.Given the wide range of ncRNAs that co-opt in programmed cell-death protein 1(PD-1)/programmed death ligand 1(PD-L1)regulation,and based on the literature,we hypothesized that miR-155-5p,miR-194-5p and long non-coding RNAs(lncRNAs)X-inactive specific transcript(XIST)and MALAT-1 are involved in a regulatory upstream pathway for PD-1/PD-L1.Recently,nutraceutical therapeutics in cancers have received increasing attention.Thus,it is interesting to study the impact of oleuropein on the respective study key players.AIM To explore potential upstream regulatory ncRNAs for the immune checkpoint PD-1/PD-L1.METHODS Bioinformatics tools including microrna.org and lnCeDB software were adopted to detect targeting of miR-155-5p,miR-194-5p and lncRNAs XIST and MALAT-1 to PD-L1 mRNA,respectively.In addition,Diana tool was used to predict targeting of both aforementioned miRNAs to lncRNAs XIST and MALAT-1.HCC and normal tissue samples were collected for scanning of PD-L1,XIST and MALAT-1 expression.To study the interaction among miR-155-5p,miR-194-5p,lncRNAs XIST and MALAT-1,as well as PD-L1 mRNA,a series of transfections of the Huh-7 cell line was carried out.RESULTS Bioinformatics software predicted that miR-155-5p and miR-194-5p can target PDL1,MALAT-1 and XIST.MALAT-1 and XIST were predicted to target PD-L1 mRNA.PD-L1 and XIST were significantly upregulated in 23 HCC biopsies compared to healthy controls;however,MALAT-1 was barely detected.MiR-194 induced expression elevated the expression of PD-L1,XIST and MALAT-1.However,overexpression of miR-155-5p induced the upregulation of PD-L1 and XIST,while it had a negative impact on MALAT-1 expression.Knockdown of XIST did have an impact on PD-L1 expression;however,following knockdown of the negative regulator of X-inactive specific transcript(TSIX),PD-L1 expression was elevated,and abolished MALAT-1 activity.Upon co-transfection of miR-194-5p with siMALAT-1,PD-L1 expression was elevated.Co-transfection of miR-194-5p with siXIST did not have an impact on PD-L1 expression.Upon co-transfection of miR-194 with siTSIX,PD-L1 expression was upregulated.Interestingly,the same PD-L1 expression pattern was observed following miR-155-5p cotransfections.Oleuropein treatment of Huh-7 cells reduced the expression profile of PD-L1,XIST,and miR-155-5p,upregulated the expression of miR-194-5p and had no significant impact on the MALAT-1 expression profile.CONCLUSION This study reported a novel finding revealing that opposing acting miRNAs in HCC,have the same impact on PD-1/PD-L1 immune checkpoint by sharing a common signaling pathway.

Prevalence and Years Lived with Disability for Dental Caries among Children Aged 0-14 Years in China, 1990-2016

The estimate of dental caries among Chinese children at the microscale level using standard methodology remains unclear. In this study, we assessed and analyzed the disease burden of childhood dental caries in China by extracting data from the Global Burden of Disease, Injuries, and Risk Factors Study 2016 （GBD 2016）. In 2016, the number of cases, prevalence, years lived with disability （YLD）, and age-standardized YLD rate of dental caries was 93.0 million, 43.0%, 32,200 person years, and 14.8 per 100,000, respectively. Across 33 provincial units, the disease burden was highest in Hubei （YLD rate 28.6 per 100,000）, lowest in Macao （9.1 per 100,000）, while geographical clustering was not observed. Compared with 1990, the prevalence in 2016 decreased from 46.8% to 43.0%, and the YLD rate decreased from 16.5 per 100,000 to 14.8 per 100,000. Given the slight decrease in dental caries burden, the prevalence and disease burden remained high among Chinese children. Strategies for addressing the spatial inequity of childhood dental caries require geographical targeting.

Factors Influencing Preventive Behaviors of Mothers for Diarrhea in Children Aged 1-5 Years in Buol District, Indonesia

This study aims to determine the factors related with mothers＇ behaviors in preventing diarrhea in children aged 1-5 years inBuol District. This was a cross-sectional survey design with health belief model as the conceptual framework. A total of 300mothers were selected by using purposive sampling method based on criteria. Mothers were interviewed by using astructured questionnaire during October to November 2015. A chi-square （X^2） test was used to determine a significantassociation between independent variables and dependent variable. The finding showed that 68.3% of mothers hadgood behaviors in preventing diarrhea. The factors significantly related to mothers＇ behaviors included perceivedsusceptibility to diarrhea, perceived severity of diarrhea, perceived benefits of diarrhea prevention behaviors, and perceivedbarriers of diarrhea prevention behaviors CP 〈 .01, p 〈 .01, p 〈 .01, and p 〈 .01 respectively）. Further, mothers had highperception to comply with diarrhea prevention behaviors. Those who perceived that diarrhea prevention behaviors werehighly beneficial to their children had good behaviors in preventing diarrhea. However, taking certain actions must considernegative aspects.

Energy Balance-related Behaviors Are Related to Cardiometabolic Parameters and Predict Adiposity in 8-14-year-old Overweight Chinese Children One Year Later

To identify target energy balance-related behaviors（ERBs）,baseline data from 141overweight or obese schoolchildren（aged 8-14years old）was used to predict adiposity[body mass index（BMI）and fat percentage]one year later.The ERBs included a modified Dietary Approach to Stop Hypertension diet score（DASH score）,leisure-time physical activity（PA,days/week）,and leisure screen time（minutes/day）.Several cardiometabolic variables were measured in the fasting state, including systolic blood pressure （SBP）, diastolic blood pressure （DBP）, blood glucose （GLU）, total cholesterol （TC）, triglycerides （TG）, low-density lipoprotein （LDL-C）, and high-density lipoprotein （HDL-C）.

Pesticide Residue Control in the Years 1983-1985

Levels of organochlorinated, organophosphate, dithiocarbamic, benzimidazolic, and phthalimidic compounds, as well as some other pesticide residues obtained from Regional Laboratories in the years 1983-1985, were assembled and presented as a part of a study aimed at evaluating food contamination. Approximately 2000 samples of vegetables, fruits, cereals, and food of animal origin were analyzed by local laboratories during the years 1983, 1984, and 1985. Samples were randomly obtained from the market, at production levels, or sometimes at custom sites. Approximately 10,000 determinations of single compounds or classes of compounds were carried out. The analytical results are presented and compared with the Italian maximum residue limits. In the majority of the samples analyzed, either there were no residues or the residues were below the permitted level for the specific pesticide in each commodity. High levels of residues were present in a few cases, mainly with respect to some fungicides in fruits and vegetables and chlorinated compounds in some animal products. (c)1989 Academic Press, Inc.

Pesticide Residue Control in the Years 1986-1987

Results of analytical surveys on pesticide residue levels in foods for the years 1986-1987 are presented. Analytical data obtained from regional laboratories are tabulated in terms of various commodity groups (vegetables, fruit, cereals, processed or derived foodstuffs, other commodities, legumes, environmental samples, others) and are compared with maximum legal tolerances established by the ministerial ordinance (Italian Ministry of Health) 6.6. 1985.On a total number of 4715 determinations of classes of compounds or of single compounds made on 1601 commodities samples, only N 53 (1.1 %) violative results appeared. No residue was found at levels exceeding regulatory limits or found in commodities where a tolerance had not been established for a specific pesticide/commodity combination.

Pesticide Residue Control in the Years 1988-1989 in Italy

The paper reports the monitoring for pesticide residue contamination of foodstuffs carried out in the years 1988-1989 by the Italian peripheral laboratories officially commissioned for the task. The tables show the analytical data for each class of substrate versus the limits in force at the time. 2506 food samples and 555 samples from the environment were analysed and a total of 16259 determinations made.The residues were absent in 90% of the cases; the percentage of irregularities was 1.52%. These results confirm the data obtained in previous years, which is particularly significant considering the much larger number of analytical determinations performed this time.It has been deemed convenient to survey specific types of foodstuffs (for example, cereals and animal products) by examining a larger number of samples.

Uptake of Two Doses of HPV Vaccines in Nakuru County, Kenya: A Case of Rongai and Nakuru West Sub-Counties

Background: HPV vaccines were introduced globally as one of the most effective strategies to prevent cervical cancer. HPV vaccines were rolled out in Kenya in 2019 targeting girls aged 10 - 14 years, but the uptake has not been satisfactory. The Purpose of the Study: The aim of the study was to assess the level of HPV uptake among girls aged 10 - 14 years in Rongai and Nakuru West Sub-Counties in Nakuru County. Method: This was a cross-sectional study where data on HPV uptake was retrieved from all the public health facilities located in Rongai and Nakuru West Sub-Counties, Nakuru County, entered into Microsoft Excel then transferred to SPSS version 26 for analysis of HPV vaccine uptake since the year 2019 to June 2022. Data Analysis: Descriptive statistics were used where tables and graphs were generated to represent the percentages and trends of HPV vaccine uptake. Results: The average percentage of HPV uptake in Nakuru West Sub-County since the rollout of vaccination was 17% while that of Rongai Sub-County was 15%. In 2019, HPV 1 uptake was generally low for both Sub-Counties, the results show no HPV 2 vaccines were administered during that year. In 2020, Nakuru West reported an increase in HPV 1 uptake, while Rongai reported a drop in HPV 1 uptake. Both Sub-Counties reported an increase in HPV 2 in 2020 as compared to the previous year. The highest HPV 1 & 2 uptakes were reported in 2021 in both Sub-Counties. The uptake of both HPV 1 & 2 kept increasing subsequently. Conclusion: The overall uptake of HPV vaccines for Doses 1 and 2, in both Rongai and Nakuru West Sub-Counties, is low. However, there has been a consistent increase in uptake of the two doses in the two Sub-Counties since 2019. Therefore, raising public awareness of the importance of HPV vaccination could improve uptake.
