The Use of Nutritional Supplements Among Recreational Athletes in Athens, Greece

Although the use of nutritional supplements by professional athletes and the benefits thereof have been extensively studied, information on recreational athletes' use of supplements is limited. This study investigated the consumption of nutritional supplements, source of information and supply of supplements, and level of awareness with regard to the relevant legislation among individuals who undertake regular exercise in Athens, Greece. A closed-ended, anonymous questionnaire was answered by 329 subjects (180 men, 149 women), age 30.6 +/- 12.1 yr, from 11 randomly selected gym centers. Preparations declared as anabolic agents by the users were submitted to a gas chromatographic analyzer coupled to a mass spectrometric detector. Consumption of nutritional supplements was reported by 41% of the study population, with proteins/amino acids and vitamins being the most popular. Age (r = .456, p = .035), sex (chi(2) = 14.1, df = 1, p < .001), level of education (chi(2) = 14.1, df = 3, p < .001), and profession (chi(2) = 11.4, df = 4, p = .022) were associated with the subjects' decision to consume nutritional supplements. Most (67.1%) purchased products from health food stores. Only 17.1% had consulted a physician or nutritionist, and one third were aware of the relevant legislation. Two preparations were detected containing synthetic anabolic steroids not stated on the label. In conclusion, use of nutritional supplements was common among recreational athletes in Athens, Greece. A low level of awareness and low involvement of health care professionals as sources of information and supply were observed

Assessment of self-reported self-esteem in healthy and diabetic children and adolescents in Greece

Background: The aim of the present study was to evaluate any possible negative effect of diabetes on the self-esteem of children and adolescents with diabetes. Methods: Self-esteem was evaluated using the Culture-Free Self-Esteem Inventory (CFSEI-2) in 144 patients with Type 1 diabetes mellitus (T1DM; 7-18 years of age) treated in a diabetes center and compared against that of 136 healthy children and adolescents. Results: Self-esteem was correlated with age (P = 0.017), but not with diabetes (P = 0.886). The median CFSEI-2 score for both healthy and diabetic children was 22. There was no significant correlation between self-esteem and sex, body mass index (BMI), physical exercise, HbA1c or parental educational level. According to Spearman&apos;s rank correlation coefficient (rs), there was a significant association between age and self-esteem (rs = -0.15). Conversely, although BMI (rs = -0.09) and treatment duration (rs = -0.107) had a slight negative effect on self-esteem and the duration of physical exercise (rs = 0.11) and parental education (rs = 0.07) seemed to have a positive effect, the associations did not reach statistical significance. Conclusions: Self-esteem in diabetic children is mainly affected by their age, level of physical activity and level of family support. These findings emphasize the need to discriminate between glycemic control and diabetic adjustment. © 2010 Ruijin Hospital, Shanghai Jiaotong University School of Medicine and Blackwell Publishing Asia Pty Ltd

Hepatitis a among refugees, asylum seekers and migrants living in hosting facilities, Greece, April to December 2016

An increased number of hepatitis A cases among refugees, asylum seekers and migrants residing in hosting facilities in Greece were recorded between April and December 2016. In total, 177 laboratory-confirmed symptomatic cases were reported; of these, 149 (84%) occurred in hosting camps mostly among Syrian children under 15 years. All cases reported symptom onset after their entry into the country. Public health interventions focused on hygiene measures and vaccination. © European Centre for Disease Prevention and Control (ECDC). All rights reserved

Resistant Shigella strains in refugees, August-October 2015, Greece

Shigellosis is endemic in most developing countries and thus a known risk in refugees and internally displaced persons. In 2015, a massive influx of refugees into Greece, due to the political crisis in the Middle East, led to the development of appropriate conditions for outbreaks of communicable diseases as shigellosis. We present a cluster of 16 shigellosis cases in refugees, detected by the implementation of a syndromic notification system in one transit centre in Athens, between 20 August and 7 October 2015. Both Shigella flexneri (n = 8) and S. sonnei (n = 8) were identified, distributed in various serotypes. All tested isolates (n = 13) were multidrug resistant; seven were CTX-M-type extended-spectrum β-lactamase producers. Our results indicate lack of a potential common source, although pulsed-field gel electrophoresis typing results revealed small clusters in isolates of the same serotype indicating possible limited person-to-person transmission without identifying secondary community cases related to the refugees. To prevent the spread of shigellosis, empirical antibiotic treatment as well as environmental hygiene measures were implemented. The detection of multi-drug resistance is important for determining the appropriate empirical antibiotic treatment for the more severe cases, while at the same time real-time typing is useful for epidemiological investigation and control measures. © Cambridge University Press 2016

Vasovagal reactions in blood donors during or immediately after blood donation

SUMMARY. The aim of the study was to estimate the type, incidence and causes of donor adverse reactions during and after blood donation in a Greek Blood Bank, where medical staff is responsible for donor selection. 12 173 blood donors were studied for adverse reactions. One-hundred and seven (0Á87%) donors had a vasovagal reaction during or after blood donation. Donors who gave blood occasionally had a significant greater incidence of reactions compared with volunteer donors (1Á15 versus 0Á53%) (P &lt; 0Á001). There was no significant difference between men and women (0Á85 versus 0Á95%). First-time donors (1Á7 versus 0Á68%) and those under 30 years (1Á15 versus 0Á71%] had a significant greater possibility to have a reaction (P &lt; 0Á001). Twenty-two of 107 (20Á5%) donors had a syncopal reaction. There was not a causative correlation of haematocrit, haemoglobin, systolic and diastolic blood pressure, pulse rate and weight in women (except weight in men) in developing a reaction. The stressing experience of phlebotomy was the reason for the higher frequency of a reaction. The incidence of reactions in our donors is lower than in other studies, and the possible reason for this is that only physicians are responsible for the selection of donors and trained personnel are careful of them during the donation process

A severe gastroenteritis outbreak of Salmonella enterica serovar Enteritidis PT8, with PFGE profile XbaI.0024 and MLVA profile 2-9-7-3-2 following a christening reception, Greece, 2016

In June 2016, a Salmonella enterica serovar Enteritidis outbreak (n = 56) occurred after a christening reception in Central Greece, mainly affecting previously healthy adults; one related death caused media attention. Patients suffered from profuse diarrhoea, fever and frequent vomiting episodes requiring prolonged hospitalisation and sick leave from work, with a 54% hospital admission rate. The majority of cases experienced serious illness within &lt;12 h of attending the party. We investigated the outbreak to identify the source(s) of infection and contributing factors to the disease severity. From the retrospective cohort study, the cheesy penne pasta was the most likely vehicle of infection (relative risk 7.8; 95% confidence interval 3.6-16.8), explaining 79% of the cases. S. enterica ser. Enteritidis isolates were typed as phage-type PT8, pulsed-field gel electrophoresis type XbaI.0024, multiple locus variable-number tandem repeat analysis-type 2-9-7-3-2. The strain did not share the single-nucleotide polymorphism address of the concurrent European S. enterica ser. Enteritidis PT8 outbreak clusters. Following five consecutive years with no documented S. enterica ser. Enteritidis outbreaks in Greece, this outbreak, likely associated with a virulent strain, prompted actions towards the enhancement of the national Salmonella molecular surveillance and control programmes including the intensification of training of food handlers for preventing similar outbreaks in the future. Advanced molecular techniques were useful in distinguishing unrelated outbreak strains. Copyright © 2017 Cambridge University Press

Diversity of cyanobacterial phylotypes in a Mediterranean drinking water reservoir (Marathonas, Greece)

The structure of the cyanobacterial community in a large drinking water reservoir (Marathonas, Greece) was investigated in October 2007 and September 2008. Cyanobacteria-specific primers were used for the PCR amplification of cyanobacterial 16S rDNAs from three water column sites and the water collection tank. In total, 199 clones were sequenced representing 52 unique cyanobacterial, including chloroplast-related, and 11 non-cyanobacterial phylotypes. All cyanobacterial phylotypes belonged to the order Chroococcales. Cluster analysis showed that the cyanobacterial communities in 2007 in the three water column sites showed high similarity between the stations and low diversity (H = 1.17 - 1.44), due to the occurring common phylotypes, while all sites in 2008 had very low similarities between them and higher diversity (H = 1.56 - 2.40). Some of the most abundant phylotypes were closely related (>98%) to members of the genus Gloeocapsa and a potentially toxin-producing strain of Microcystis aeruginosa. The non-cyanobacterial phylotypes were either unaffiliated or belonged to the Verrucomicrobia, and were related with sequences originating from lake water habitats
