Genome-wide association study identifies DRAM1 associated with Tourette syndrome in Taiwan.

BACKGROUND: Tourette syndrome (TS) is a neurodevelopmental disorder characterized by motor and vocal tics. Several susceptibility loci associated with TS have been identified previously in populations of European descent using genome-wide association studies (GWAS). However, the exact pathogenic mechanism underlying TS is unknown; additionally, the results of previous GWAS for TS were based on Western populations, which may not translate to other populations. Therefore, we conducted a GWAS in Taiwanese patients with TS and chronic tic disorders (CTDs), with an aim to elucidate the genetic basis and potential risk factors for TS in this population. METHODS: GWAS was performed on a Taiwanese TS/CTDs cohort with a sample size of 1,007 patients with TS and 25,522 ancestry-matched controls. Additionally, polygenic risk score was calculated and assessed. RESULTS: Genome-wide significant locus, rs12313062 (p=1.43 × 10-8) and other 9 single nucleotide polymorphisms, were identified in chromosomes 12q23.2, associated with DRAM1 and was a novel susceptibility locus identified in TS/CTDs group. DRAM1, a lysosomal transmembrane protein regulated by p53, modulates autophagy and apoptosis, with potential implications for neuropsychiatric conditions associated with autophagy disruption. CONCLUSIONS: This study conducted the first GWAS for TS in a Taiwanese population, identifying a significant locus on chromosome 12q23.2 associated with DRAM1. These findings provide novel insights into the neurobiology of TS and potential directions for future research in this area.

Lesson learned from assessing teachers' and students' perspectives regarding the quality of e-learning in medical education during the pandemic: a mixed-methods study.

BACKGROUND: The evaluation of e-learning systems ensures the provision of quality training. The goal was to identify the perspectives of teachers and students on e-learning in medical education during the COVID-19 pandemic at Shiraz University of Medical Sciences (SUMS), Iran. METHODS: This study utilized a convergent mixed methods research design with a two-phase approach to collect and analyze data between June and August 2022. In the first stage, a cross-sectional descriptive study was conducted to evaluate the quality of e-learning systems from the perspective of 400 students. In the second stage, semi-structured interviews were conducted with 10 virtual education professors and 10 student representatives to identify the strengths, weaknesses, opportunities, and threats of virtual education. A validated questionnaire was administered to assess the quality of the e-learning system, and data were analyzed using SPSS-21. Qualitative data were subjected to content analysis. RESULTS: Our findings revealed that the student support system, the course structure, and the infrastructure and technology subscales' mean scores were significantly higher than the average level (P < 0.001). However, the professors' methods of teaching and learning strategies were unsatisfactory. The results of the present study showed that the evaluation mean score was significantly higher among, younger, female, and undergraduate students. Virtual education has strengths and weaknesses, and innovative approaches are needed to enhance student engagement. The lack of appropriate infrastructure and virtual teaching tools for teachers and students is a significant challenge that needs to be addressed. Blended learning is effective in medical education, and the shift from teacher-centered to learner-centered teaching approaches is an opportunity to explore innovative teaching approaches. CONCLUSION: From the perspective of students, the quality of eLearning systems at the universities was moderate. Virtual education offers both benefits and drawbacks, and there is a requirement for innovative solutions to enhance student engagement and lessen boredom.

Identification of the efficacy of parentage testing based on bi-allelic autosomal single nucleotide polymorphism markers in Taiwanese population.

Parentage testing is crucial for forensic DNA analysis, using short tandem repeats (STRs). Single nucleotide polymorphisms (SNPs) with high minor allele frequency (MAF) are promising for human identification. This study aimed to develop SNP markers for parentage testing in the Taiwanese population and compare their accuracy with STRs. The TPMv1 SNP microarray (714,457 SNPs) was used to screen 180,000 Taiwanese individuals and analyze the SNP data using PLINK. After quality control, allelic distribution, and MAF considerations, a set of SNPs with significant inheritance information was selected. Parentage testing was conducted on 355 single parent-child pairs using both STRs and SNPs, employing three kinship algorithms: identity by descent, kinship-based inference for genome-wide association studies, and the combined paternity index/probability of paternity (CPI/PP). An Affymetrix signature probe for kinship testing (ASP) was also used. Based on the quality control and selection criteria, 176 SNPs with MAF > 0.4995 were selected from the Taiwanese population. The CPI/PP results calculated using SNPs were consistent with the STR results. The accuracy of the SNPs used in the single-parent-child parentage testing was > 99.99%. The set of 176 SNPs had a higher identification rate in the single parent-child parentage test than in the ASP. The CPI/PP value calculated using 176 SNPs was also more accurate than that calculated using ASP. Our findings suggest that these 176 SNPs could be used for single-parent-child parentage identification in the Taiwanese population.

Impact of Medical School on the Relationship between Nutritional Knowledge and Sleep Quality-A Longitudinal Study of Students at Wroclaw Medical University in Poland.

The aim of this study was to investigate the impact of the first year of medical school on the relationship between nutritional knowledge and sleep. To achieve this, first-year medical students at Wroclaw Medical University were invited to participate in the study during both the initial and final months of their first academic year. The study included 570 students in the initial period and 705 in the latter. The research questionnaire comprised the KomPAN, assessing nutritional knowledge, and the Pittsburgh Sleep Quality Index (PSQI), evaluating sleep quality. The majority of students demonstrated at least sufficient nutritional knowledge, while approximately two-thirds of students experienced poor sleep in both periods. Notably, sleep quality further deteriorated in the second period (PSQI total score: 6.86 vs. 7.38, p = 0.0157). This change was influenced mainly by a decrease in sleep duration and an increase in the use of sleep medications (both p < 0.0001). The significant difference in overall sleep quality between different nutritional knowledge levels emerged only in the second semester, where students with the highest nutritional knowledge slept the best, while those with the lowest slept the worst (p = 0.0001). Crucially, in both periods, the use of sleep medications was highest among individuals with insufficient nutritional knowledge. Throughout the academic year, the usage increased for all except those with the highest nutritional knowledge, who exhibited the best sleep (p < 0.0001). The escalating use of sleep medications among medical students warrants greater attention, and leveraging the relationship between nutritional knowledge and sleep could prove beneficial, as positive habits in one domain may positively influence the other.

[Welcoming learners, a DEPHI on the DMU!] / L'accueil des apprenants, un DEPHI sur le DMU !

The reception of learner-caregivers is a challenge for the care sectors in the context of clinical training, moreover in view of the current situation in connection with the health of our hospitals. Remember that internship periods represent 50 % of apprenticeship time in training institutes. So how does a Medical-University Department of Hematology and Immunology try to implement a policy of welcoming and supporting trainees, taking into account their level of training and promoting interest and emulation for future professionals health?

Relation between Guillain-Barré syndrome and Covid-19: Case-Series.

Approximately two-thirds of the Guillain-Barré syndrome (GBS) cases are preceded by upper respiratory tract infection or enteritis. There has been previous documentation of a clear association between Covid-19 and GBS. Covid-19 can affect the nervous tissue either through direct damage or through triggering a host immune response with subsequent development of autoimmune diseases such as GBS. Covid-19 can affect the host`s immune system through the activation and interaction of the T-and B-lymphocytes with subsequent production of antibodies that cross-react with the gangliosides. Depending on the nature of the neuronal autoimmune destruction, the affected individual may have either a demyelinating or axonal subtype of GBS. These subtypes differ not only in symptoms but also in the likelihood of recovery. This report presents two cases of GBS that developed after the respiratory symptoms of Covid-19. Their neurological features indicated demyelination, axonal damage, irritation of spinal nerve roots, and impaired sensory and motor transmission with additional facial nerve palsy in the second-studied case. This case report highlights the relationship between GBS and Covid-19 infection.

Knowledge of HPV and HPV Vaccination among Polish Students from Medical and Non-Medical Universities.

Human papillomavirus (HPV) is a common sexually transmitted infection that can cause both benign and malignant lesions. HPV vaccines, preferably administered before the onset of sexual activity, have demonstrated remarkable efficacy in preventing HPV-related cancers. The impact of a healthcare provider's recommendation on HPV vaccine acceptance is substantial. Therefore, medical students must undergo thorough training in this domain. This study compares fundamental understanding and viewpoints regarding HPV and anti-HPV vaccines among Polish students pursuing medical and non-medical sciences. This study was based on the authors' questionnaire, and the results were statistically analyzed. The participants in this study were 1025 students (medical sciences students-520 respondents in total; and non-medical sciences students-505 respondents in total). According to the results, medical students' knowledge about the consequences of HPV infection and vaccination against HPV was significantly greater. To date, numerous publications have investigated the understanding of particular social, gender, parental, etc., groups about vaccination, but the knowledge of students at different universities-medical and other-has not been compared. Social awareness is still insufficient, even in groups of medical students. There is much to be done to educate and encourage preventive behavior in those not receiving primary prevention in early childhood.

[The higher level of anxiety as a significant risk factor in evaluating health and social self-feeling in students of medical university].

The success of adaptation of students to conditions of educational process in Medical University is determined by complex of accompanying socio-psychological factors. The level of personal anxiety determines severity of impact of these factors on psychosomatic state of student. The high level of anxiety among students in conditions of educating in Medical University can significantly and multi-componently impact their physical organism, success in teaching and social well-being. The purpose of the study is to determine prevalence of high levels of anxiety and their impact on health and social well-being of students of different genders, periods of study on budgetary and commercial basis. There is significant prevalence of high levels of personal anxiety among students of first year of education (57.0%), which tends to increase by fourth year (75.5%). The increased anxiety has significant impact on morbidity (correlation with anxiety levels τ=0.69 and τ=0.40 for men and women, respectively) and social well-being of students, their behavior and lifestyle. The female students are the most affected by anxiety factor. The belonging of students with high level of anxiety to budget or commercial group determines specificity their response to conditions of education in the Medical University. The obtained results should be used to improve efficiency of adaptation and psychological support of students in the process of education in Medical University. The high level of anxiety in students should be taken into account in preventive activities of preserving health of students as separate factor, impacting similarly with strong health risk factor on their physical organism and social well-being, considering gender and period of study on budgetary or commercial basis.

The chain mediating role of psychological resilience and neuroticism between intolerance of uncertainty and perceived stress among medical university students in Southwest China.

BACKGROUND: Medical university students are confronted with unprecedented uncertainty and stress compared with their peers. Research has explored the effect of intolerance of uncertainty on perceived stress, but little attention was paid to investigate the mediating mechanisms behind this relationship, especially among medical university students. The aim of this study was to examine whether psychological resilience and neuroticism played a mediating role between medical university students' intolerance of uncertainty and perceived stress. METHODS: A total of 717 medical university students from Chongqing in Southwest China were recruited to participate in our study and completed demographic information, Intolerance of Uncertainty Scale Short Version (IUS-12), Chinese Version of Perceived Stress Scale (CPSS), Connor-Davidson Resilience Scale-10 (CD-RISC-10) and Eysenck Personality Questionnaire (EPQ). RESULTS: (1) Significant correlations between intolerance of uncertainty, perceived stress, psychological resilience and neuroticism were found. (2) Intolerance of uncertainty affected medical university students' perceived stress via three paths: the mediating effect of psychological resilience, the mediating effect of neuroticism, and the chain mediating effect of both psychological resilience and neuroticism. CONCLUSIONS: Intolerance of uncertainty could directly affect the perceived stress of medical university students, and also affected perceived stress through the mediating roles of psychological resilience and neuroticism, as well as through the chain mediating role of these two variables.

Support for affirmative actions to increase inclusivity of intersex* persons at an Austrian medical university.

BACKGROUND: Since the ruling handed down by the Austrian Constitutional Court in 2018 intersex variation has been recognized under Austrian law as a "third sex". In order to ensure that people with intersex variation are not discriminated against based on their group membership affirmative actions (i.e., proactive practices to avert discrimination) can be implemented. The current study explored whether students and employees at an Austrian medical university know about intersex variation. Furthermore, the study investigated what affirmative actions are practiced at the medical university to be inclusive for intersex persons and students' and employees' support for such affirmative actions. METHODS: All students and employees of a medical university in Austria were invited by e-mail to participate at the current study that included a self-constructed knowledge test on intersex variation with ten true-false questions. On five-point Likert scales participants reported for each of twelve listed affirmative actions whether they had seen a certain affirmative action at their university and how important they thought the implementation of an affirmative action was. Finally, participants' gender, age, sexual orientation, highest level of education, and nationality was assessed. A cluster analysis was performed to determine groups of people with different degrees of support for affirmative actions for intersex persons. RESULTS: 220 students (62% cisgender women, 38% cisgender men) and 200 employees (72% cisgender women, 28% cisgender men) participated. Participants responded correctly to three out of ten knowledge test questions. The cluster analysis revealed that participants could be clustered as heterosexual cisgender women (Cluster 1; 55%), heterosexual cisgender men (Cluster 2; 30%), or sexual minority cisgender women and men (Cluster 3; 15%). Sexual minority persons knew more about intersex variation than did heterosexual participants. On average, affirmative actions for the inclusivity of intersex people have not been encountered (M = 1.5, SD = 0.4) at the studied university. Participants, especially those in Cluster 3, believed that the listed actions are moderately important. CONCLUSIONS: At the medical university many actions should be taken to increase inclusivity for intersex people. Increasing the knowledge of university staff and students concerning intersex might help increase their support for such actions.

Medical Education in Armenia: An Overview.

This article serves to describe the medical education system of Armenia, a country located in the cross-section of Europe and Asia. Similar to other countries in the region, its medical education system is structured into undergraduate (6 years), postgraduate (1-4 years), and continuing education components. Its largest medical university, Yerevan State Medical University (YSMU), is the predominant institute for medical education and has enrollment of not only Armenian citizens, but also international students from India, Iran, Russia, and other countries. According to publication metrics, research activity at YSMU is increasing. Finally, the unique relationship between the country and its global diaspora has facilitated collaborative efforts in not only medical education, but also the delivery of care and capacity building. Significant challenges remain for each stage of medical education, such as the lack of standardized licensing or board examinations and oversight of the number of resident physicians per specialty.

[The rise of attractiveness of specialty "General Practice" for graduates of medical universities].

The choice of specialty by graduate of medical university can be promoted by particular social, demographic and personal characteristics. Purpose of the study is to investigate demographic, social and personal characteristics of students in residency on specialty "General Medical Practice" in the Russian Federation. The sociological, statistical and analytical methods are applied. The sampling for survey consisted of 81 respondents. The specialty "General Medical Practice" is chosen mainly by women residing in city, non-married and without children. They are not characterized by participation in public life and they are characterized by the presence of hobbies (hobbies). The choice is conditioned by multidisciplinary nature of medical care and scope of professional horizons. They are attracted by treatment work and are less interested in pedagogy and science. In perspective, 80% of female respondents are going to get another specialty. More than 70% of respondents plan to work in out-patient conditions and predominantly in state sector of health care. For women, main goals of further professional training are improvement in main and adjoining specialties and career promotion. And in educational program, internal diseases are of greatest interest. The preferred forms of training are internships and e-learning. The main direction of improving educational process is increasing of scope of practical training. The comparative analysis of study results with data of previous publications was implemented. The factors influencing commitment to specialty are revealed. The proposals increasing attractiveness of general medical practice for graduates of medical universities and keeping in specialty after residency are formulated.

History and Metamorphosis of Hand Surgery India.

The advent of hand surgery in India reads like a fortuitous saga, a continuum of the hand deformity correction on leprosy patients pioneered by Dr. Paul Wilson Brand at the Christian Medical College (CMC) Vellore, Madras State (Tamil Nadu [TN]), in 1948. The "Hand Research Unit," established in 1951, became the largest repository for hand reconstructive surgeries and with its head-start drew in most hand dysfunctions in the country. Early industrialization and disorderly road traffic generated hand injuries that threatened workforce in India. Propitiously, a hand injury service was opened in 1971 at the Government Stanley Medical College Hospital, Chennai. The inexorable growth of hand surgery continued and incorporated the gamut of conditions that required hand care and rehabilitation, including brachial plexus injuries. Continuing Medical Education programs, Hand Surgery workshops, Indian Society for Surgery of the Hand meetings, Hand Fellowships, etc., increased the number of "hand surgery" practitioners, which drew the attention of the Medical Council of India to commence a postgraduate Hand Surgery program that it eventually gazetted. The sagacity of the members of the Board of Studies of TN Medical University honored the historical role of CMC Vellore in hand surgery and allowed it to commence the first Master of Chirurgiae Hand Surgery course in India in 2015. An intuitive understanding of 70 years of hand surgery accomplishments that redesigned and restored deformed and injured hands and protected livelihoods have made young surgeons increasingly take hand surgery as a career.

A novel prediction model of the risk of pancreatic cancer among diabetes patients using multiple clinical data and machine learning.

INTRODUCTION: Pancreatic cancer is associated with poor prognosis. Considering the increased global incidence of diabetes cases and that individuals with diabetes are considered a high-risk subpopulation for pancreatic cancer, it is critical to detect the risk of pancreatic cancer within populations of person living = with diabetes. This study aimed to develop a novel prediction model for pancreatic cancer risk among patients with diabetes, using = a real-world database containing clinical features and employing numerous artificial intelligent approach algorithms. METHODS: This retrospective observational study analyzed data on patients with Type 2 diabetes from a multisite Taiwanese EMR database between 2009 and 2019. Predictors were selected in accordance with the literature review and clinical perspectives. The prediction models were constructed using machine learning algorithms such as logistic regression, linear discriminant analysis, gradient boosting machine, and random forest. RESULTS: The cohort consisted of 66,384 patients. The Linear Discriminant Analysis (LDA) model generated the highest AUROC of 0.9073, followed by the Voting Ensemble and Gradient Boosting machine models. LDA, the best model, exhibited an accuracy of 84.03%, a sensitivity of 0.8611, and a specificity of 0.8403. The most significant predictors identified for pancreatic cancer risk were glucose, glycated hemoglobin, hyperlipidemia comorbidity, antidiabetic drug use, and lipid-modifying drug use. CONCLUSION: This study successfully developed a highly accurate 4-year risk model for pancreatic cancer in patients with diabetes using real-world clinical data and multiple machine-learning algorithms. Potentially, our predictors offer an opportunity to identify pancreatic cancer early and thus increase prevention and invention windows to impact survival in diabetic patients.

Using medical university websites for health education about COVID-19; an effective solution for public education during a pandemic.

BACKGROUND: Medical universities use their websites to teach, research, and promote a culture of health. Therefore, this study aimed to evaluate the performance of medical universities in terms of health information and education regarding COVID-19 by surveying the website of Iranian medical universities. METHODS: This descriptive-analytical study was conducted in June to August 2020 on the websites of medical universities in three categories of universities (type 1, type 2 and type 3). The information of this study was collected from medical universities located in the east, west, north, south and center of Iran. Data were collected according to a checklist. The checklist contained 3 sections; the first part with 8 components regarding general information of the university websites, the second part with 11 components regarding the information and news related to the coronavirus and the third part with 12 components regarding the content of personal health education and environmental health for the prevention of coronavirus. To determine the status of each website in the two areas of health information and education, websites were divided into three categories based on scores (poor, average and good). Data were analyzed by chi-square. RESULTS: In this study, 1118 web pages related to 48 Iranian universities of medical sciences were reviewed, where 19 were type 1 universities, 21 type 2 universities, and 8 type 3 universities. The mean scores of the websites regarding the information and news related to the coronavirus (8.54 ± 1.750) and the mean scores of the websites regarding the personal and environmental health education related to coronavirus (10.96 ± 1.148) were in a favorable and positive condition. The ranking of medical universities by type showed that the scores in the two areas of health information and education about the coronavirus were in good condition and none of the universities were in bad condition. Chi-square showed that the information status and news related to the coronavirus had a significantly positive relationship with the type of medical universities (χ2 = 10.343, p = 0.006). CONCLUSIONS: The results of this study showed that type1 and type 2 and 62.5% of type 3 medical universities were in good condition in terms of total scores in the two areas of health information and education about coronavirus and none of the universities were in a bad situation. It is suggested that the website of medical universities can serve as a reliable and appropriate source of information not only for academics and students but also for the general public.
