The aim of the current study is to evaluate the prevalence of overweight and obesity in children.
Material and methods: Two thousand three hundred and seventy-four pupils in primary education were considered for the study (1206 boys and 1168 girls).
Results: In the population-based study, the proportion of overweight children was 23.9%, of obese children 7.3%, and of those with central obesity 35.5%.
The boys were obese in a higher percentage than the girls (9.2% vs. 5.3%, p < 0.05). The obesity rates were gradually reduced as the children were growing older. The nutritional habits which were identified to have a positive association with obesity were the following: skipping breakfast, not consuming fruits and vegetables, and consuming bread and soft drinks. Children’s healthy nutrition in school was related to lower rates of generalised and central obesity, while the hours spent watching TV were positively associated with all types of obesity.
Conclusions: Results from the study suggest that a high proportion of children are overweight or obese. Therefore, it is important to adhere to a healthy lifestyle which emphasizes healthy food choices and habits, regular physical activity, and limiting screen time.

A significant number of healthcare professionals suffer from some kind of mental illness, and sometimes a very serious one. The aim of the present study was to investigate the risk of psychiatric morbidity among the medical and nursing staff of a public medium-sized general hospital. Methods: One medium-sized local general hospital took part in the study. A total number of 201 medical and nursing professionals aged 21-58 years comprised the sample of the study. A research protocol was submitted to the scientific committee of the Hospital, which in its turn granted approval. A questionnaire that investigates psychiatric morbidity, its Greek standardized version that is, was used as our instrument of choice and it was tested for validity and reliability which were found to be satisfactory (Cronbach's a= 0.883). Strict anonymity was observed. The SPSS 16.0 was used for the statistical analysis. Results: Psychiatric morbidity can have an impact on people's quality of life; elements of anxiety are the main risk factor in all four quality of life Domains included in the WHOQOL-BREF instrument. Somatization is also a risk factor regarding Domain 1 (physical health and level of independence). Elements of stress and distress are nothing but common in the medical/nursing staff that participated in this study. Conclusions: All relevant studies eventually aim at developing appropriate psychosocial interventions, both preventive and supportive, for this particular group of professionals.

Furthermore, Single Photon Emission Computed Tomography (SPECT) and Positron Emission Tomography (PET) brain studies provide information in early diagnosis, differential diagnosis, development of new drugs, and monitoring the response to therapeutic management. SPECT and PET brain imaging require the use of radiopharmaceuticals that cross the intact Blood Brain Barrier (BBB). Such radiotracers have been used in regional Cerebral Blood Flow (rCBF) SPECT and PET imaging and brain metabolism imaging with PET; these are well established methods in the diagnosis and management of various cerebral vascular diseases (e.g. stroke, dementia, epilepsy). Advances in radiotracer chemistry have resulted in the development of molecular imaging which represents the molecular and cellular processes of neuropsychiatric diseases. SPECT and PET molecular imaging has become available for the study of acetylcholinergic, dopaminergic and serotonergic systems, as well as for benzodiazepine and opioid receptors, with promising results. More studies are needed to validate the role of molecular imaging in the clinical practice of neuropsychiatric disorders.

Ghrelin has a crucial role in the regulation of food intake and energy homeostasis, and adiponectin is secreted by adipocytes, and it has been proposed to mediate obesity-related insulin resistance. Both they are playing a critical role in a variety of physiological processes including endocrine, metabolic, cardiovascular, and other actions. Furthermore, other potential clinical applications of ghrelin include the treatment of patients with diabetes mellitus and infections, likewise adiponectin plays an important role in diagnosis of cardiovascular disease. Conclusions: Further studies need to specify the accurate results and the action mechanisms of adiponectin in order to facilitate the clinical practice; as well as to clarify the role of these adding a new knowledge in international scientific community.

METHOD Patients with DM were recruited from the diabetic outpatient departments of hospitals in the Attica region and Korinthos, 164 in total, 72 men and 92 women, with a mean of age 66.9±11.53 years. The tools that were used were the scale of self-assessment of depression of Zung (ZDRS) and a structured questionnaire covering demographic data, body measurements and information concerning the course of the disease. Statistical analysis was performed using Statistical Package for Social Sciences (SPSS) v. 18.0. RESULTS Regarding the somatometric status, 57.3% of patients were overweight and 30.5% obese, with high rates of central obesity (83.3% in the men and 92.4% in the women). A high body mass index [r=0.309, p=0.001] and central obesity [t(162)=4.773, p=0.001] were significantly associated with depression ...
