Impact of COVID-19 pandemic on medical education in Greece: A cross-sectional study.

BACKGROUND: Medical education was widely affected by the Coronavirus disease 2019 (COVID-19) pandemic. Long-distance learning was implemented over the traditional educational paradigm. Clinical clerkships were canceled, and evaluation methods were altered. This study aims to assess this multifaceted impact on the Greek undergraduate medical community. METHODS: A cross-sectional survey study was conducted. All undergraduate medical students at Greek Universities were addressed using social media. The data were post-stratified according to the population's male-to-female ratio and underwent descriptive and inferential statistical analysis. Associations were determined using chi-square and Fisher's exact test. A linear regression model was developed to investigate the factors that contributed to the overall impact of the pandemic on medical education. RESULTS: A total of 905 responses were analyzed, representing 9.8 % of Greece's medical students. Most reported decreased duration of laboratory (n =711, 78.5 %) and clinical (n =526, 96.7 %) practice. The majority stated that their ability to perform practical skills was affected negatively (n =805, 89.0 %). The impact on student's education was positively associated with their psychological impact. Therefore, a more negative effect on the student's education was observed on those whose psychology was affected more negatively [ß =0.49, 95 % confidence interval (CI): 0.40, 0.58, p <0.001). Additionally, the pandemic's overall impact on medical education was much more unfavorable for the clinical than the pre-clinical students (ß =-0.30, 95 % CI: -0.40, -0.20, p <0.001). CONCLUSIONS: This study's findings agree that the COVID-19 pandemic has severely impacted the education and personal life of medical students, especially in the advanced years. An insight into their specific needs to overcome the impact on their education is provided. The necessity of future mitigating actions is underlined. Emphasis should be given to clinical skills and enhancing the students' adaptive behavior to attenuate the consequences on their psychology, social life, and future healthcare provider careers.

Food insecurity and Mediterranean diet adherence among Greek university students.

AIM: To assess Mediterranean diet (MD) adherence and food insecurity (FI) among university students in Greece. METHODS AND RESULTS: A non-probability sample of 236 students was recruited from Athens and Thessaloniki during 2016. FI was assessed with the Household Food Insecurity Access Scale and MD adherence with the MEDAS questionnaire. Mean MEDAS score of the sample was 6.4 ± 1.9, with women demonstrating greater MD adherence compared to men (p = 0.016) and Dietetics students exhibiting increased score compared to the rest (p ≤ 0.001). A low proportion of participants were food-secure (17.8%), 45.3% were severely food-insecure, 22.0% experienced moderate FI and the remaining 14.8% had low FI. Participants studying in the city they grew up exhibited lower FI compared to those studying in other cities (p = 0.009), while, additionally, a trend was noted for increased FI among students with an unemployed family member (p = 0.05). Students working night shifts had lower MD adherence and increased FI compared to the rest (p = 0.004 and p = 0.003, respectively). The same pattern was observed among participants who smoked (p = 0.003 for MD adherence and p = 0.009 for FI, respectively). Multivariate regression analyses did not reveal any connections between FI categories, waist circumference or BMI, but showed an inverse relationship between severe FI and MD adherence. CONCLUSIONS: The majority of the surveyed university students from Greece demonstrate some degree of FI, with a great proportion being severely food-insecure. Increased FI is inversely associated with MD adherence.

Edmonton obesity staging system among pediatric patients: a validation and obesogenic risk factor analysis.

PURPOSE: The Edmonton Obesity Staging System for Pediatrics (EOSS-P) is a useful tool, delineating different obesity severity tiers associated with distinct treatment barriers. The aim of the study was to apply the EOSS-P on a Greek pediatric cohort and assess risk factors associated with each stage, compared to normal weight controls. METHODS: A total of 361 children (2-14 years old), outpatients of an Athenian hospital, participated in this case-control study by forming two groups: the obese (n = 203) and the normoweight controls (n = 158). Anthropometry, blood pressure, blood and biochemical markers, comorbidities and obesogenic lifestyle parameters were recorded and the EOSS-P was applied. Validation of EOSS-P stages was conducted by juxtaposing them with IOTF-defined weight status. Obesogenic risk factors' analysis was conducted by constructing gender-and-age-adjusted (GA) and multivariate logistic models. RESULTS: The majority of obese children were stratified at stage 1 (46.0%), 17.0% were on stage 0, and 37.0% on stage 2. The validation analysis revealed that EOSS-P stages greater than 0 were associated with diastolic blood pressure and levels of glucose, cholesterol, LDL and ALT. Reduced obesity odds were observed among children playing outdoors and increased odds for every screen time hour, both in the GA and in the multivariate analyses (all P < 0.05). Although participation in sports > 2 times/week was associated with reduced obesity odds in the GA analysis (OR = 0.57, 95% CI = 0.33-0.98, P linear = 0.047), it lost its significance in the multivariate analysis (P linear = 0.145). Analogous results were recorded in the analyses of the abovementioned physical activity risk factors for the EOSS-P stages. Linear relationships were observed for fast-food consumption and IOTF-defined obesity and higher than 0 EOSS-P stages. Parental obesity status was associated with all EOSS-P stages and IOTF-defined obesity status. CONCLUSIONS: Few outpatients were healthy obese (stage 0), while the majority exhibited several comorbidities. Since each obesity tier entails different impacts to disease management, the study herein highlights modifiable factors facilitating descend to lower stages, and provides insight for designing tailored approaches tackling the high national pediatric obesity rates.

Characteristics of patients with allergic rhinitis in an outpatient clinic: a retrospective study.

BACKGROUND: Allergic rhinitis affects a significant proportion of the European population. Few surveys have investigated this disorder in Greek adults. Our objective was to describe the characteristics of patients with allergic rhinitis in an adult outpatient clinic in Thessaloniki, Greece. METHODS: We studied the medical records of adult patients referred to a Clinical Immunology outpatient clinic from 2001 to 2007. The diagnostic procedure was not changed during the whole study period, including the same questionnaire used at the time of diagnosis, skin prick tests, and serum specific IgE. RESULTS: A total of 1851 patient files with diagnosed allergies were analysed and allergic rhinitis was confirmed in 711 subjects (38.4%). According to ARIA classification, persistent allergic rhinitis was more prevalent than intermittent (54.9% vs. 45.1%), while 60.8% of subjects suffered from moderate/severe disease. In multivariable analysis, factors associated with allergic rhinitis were age (for every 10 years increase, OR: 0.84, 95% CI: 0.77-0.91; p<0.001); working in school environment (teachers or students) (OR: 1.46, 95% CI: 1.05-2.02; p=0.023); parental history of respiratory allergy (OR: 2.41, 95% CI: 1.69-3.43; p<0.001); smoking (OR: 0.71, 95% CI: 0.55-0.91; p=0.007); presence of allergic conjunctivitis (OR: 6.16, 95% CI: 4.71-8.06; p<0.001); and asthma (OR: 2.17, 95% CI: 1.57-3.01; p<0.001). Analysis after multiple imputation corroborated the complete case analysis results. CONCLUSIONS: Allergic rhinitis was documented in 38.4% of studied patients and was frequently characterised by significant morbidity. Factors associated with allergic rhinitis provide insight into the epidemiology of this disorder in our region. Further studies on the general population would contribute to evaluating allergic rhinitis more comprehensively.

Prevalence of thrombophilic mutations in patients with unprovoked thromboembolic disease. A comparative analysis regarding arterial and venous disease.

BACKGROUND: Thromboembolic disease (TED) represents one of the main reasons of morbitity and mortality in Western World. Venous and arterial thrombotic disorders have long been viewed as separate pathophysiological entities. However, in recent times the separate nature of arterial and venous thrombotic events has been challenged. Although inherited thrombophilia's predominant clinical manifestation is venous thrombosis, its contribution to arterial thrombosis remains controversial. Purpose  of  the  study  was  to  evaluate  the  prevalence  of  the  most common  thrombophilic  mutations, FV Leiden G1691A-FVL and FII G20210A-PTM and to assess  the  differences between venous, arterial and mixed thrombotic events. Testing  for polymorphism MTHFR C677T and  antithrombin,  protein  C  and  protein  S was also performed. Correlations with  dyslipidemia, smoking, obesity, homocysteine and antiphospholipid antibodies were made. METHODS: 515 patients with unprovoked TED, 263 males, median age 44 years, were studied. Patients were divided into three groups: 258 with venous thrombosis (group A), 239 with arterial (group B) and 18 with mixed episodes (group C). All patients were interviewed regarding family history of TED, origin, smoking and dyslipidemia. Body mass index (BMI) had been calculated. Molecular assessment of the FVL, PTM and MTHFR C677T was performed. Antithrombin, protein C, protein S, APCR, homocysteine, antiphospholipid antibodies and lipid profile were also measured. RESULTS: The population studied was homogenous among three groups as regards age (p=0.943), lipid profile (p=0.271), BMI (p=0.506), homocysteine (p=0.177), antiphospholipid antibodies (p=0.576), and positive family history (p=0.099). There was no difference in the prevalence of FVL between venous and arterial disease (p=0.440). Significant correlation of PTM with venous TED was found (p=0.001). The number of positive and negative for MTHFR presented statistically significant difference with a support in arterial disease (p=0.05). Moreover, a 2-fold increase in the risk of venous thrombosis in FVL positive patients (odds ratio: 2.153) and a positive correlation of homocysteine levels with MTHFR C677T (p<0.001) was found. CONCLUSIONS: Correlation of PTM with venous thrombosis was established. Analysis showed no difference in prevalence of FVL between venous and arterial thrombosis, indicating that FVL might be a predisposing factor for arterial disease. A significant increase in MTHFR C677T prevalence in arterial disease was found. In conclusion, young patients with unprovoked arterial disease should undergo evaluation for thrombophilic genes. Identification of these mutations is important in the overall assessment and management of patients at high risk. Findings will influence the decisions of stratified approaches for antithrombotic therapy either primary or secondary thromboprophylaxis, the duration of therapy, the potential for avoiding clinical thrombosis by risk factor modification and the genetic counselling of family members. However, further studies are needed to clarify the nature of the association regarding venous and arterial thrombotic events.

Euthanasia in Greece: moral and ethical dilemmas.

Euthanasia as a concept and a practice has led to enormous debate in Greece, as well as in other countries. In this study, we examined the views of the public and of professionals on the issue of euthanasia. A self-administered questionnaire of 28 items was completed by 417 subjects, and provided information about attitudes towards the moral and ethical problems of euthanasia. Psychiatric speculations which arose during the approach of this issue were seen in the majority of the responses (88.3%). Psychodynamic unconscious processes reinforced and violated mechanisms and motives in favour of, or against euthanasia. Of the respondents, 44.3% were against life extension with mechanical devices. Putative main risk factors for suicidal ideation and the desire for death were: pain 66.2%, despair 60.2%, depression 59.7%, and psychopathology 38.6%. This study thus revealed that apart from pain, psychosocial factors play a key role in leading people to ask for euthanasia. On the other hand, the knowledge of the public and professionals regarding this issue is not sufficient, and thus discussion of euthanasia by Medical Societies is needed and necessary.
