Background :The profile of “frequent visitors” at the psychiatric emergencies (PE) has not been sufficiently investigated in Greece.
In this study we aimed to investigate the prevalence and relevant parameters of frequent PE visits in a Greek University Psychiatric Hospital for the year 2017.
In a retrospective study, we analyzed data of patients who presented in the PE of Eginition University Hospital in Athens during 2017. Frequent visitors were grouped under this category if they had at least five visits per year. Clinical and sociodemographic data of the patients were further related to number of visits.
84 patients were characterized as frequent visitors carrying out 9.8% of the total number of visits. 50% were women and 70% of them were living with family members. Anxiety, depressive and psychotic symptoms were the most frequent major complaints at the time of their visit, whereas psychosocial problems were associated with increased number of visits. Moreover, in terms of the underlying diagnosis substance use disorders significantly related to more frequent visits
Psychosocial problems and the diagnosis of substance use disorders significantly correlated to the number of visits at the PE of a university hospital setting in Greece for 2017.
We describe transmission of Klebsiella pneumoniae carbapenemase-producing Escherichia coli sequence type (ST) 1193 in a group home. E. coli ST1193 is an emerging multidrug-resistant clone not previously shown to carry carbapenemases in the United States. Our investigation illustrates the potential of residential group homes to amplify rare combinations of pathogens and resistance mechanisms.
Premorbid adjustment (PA) abnormalities in psychotic disorders are associated with an earlier age at onset (AAO) and unfavorable clinical outcomes, including treatment resistance. Prior family studies suggest that familial liability, likely reflecting increased genetic risk, and socioeconomic status (SES) contribute to premorbid maladjustment. However, their joint effect possibly indicating gene–environment interaction has not been evaluated.
We examined whether family history of psychosis (FHP) and parental SES may predict PA and AAO in unrelated cases with first-episode psychosis (n = 108) and schizophrenia (n = 104). Premorbid academic and social functioning domains during childhood and early adolescence were retrospectively assessed. Regression analyses were performed to investigate main effects of FHP and parental SES, as well as their interaction. The relationships between PA, AAO, and response to antipsychotic medication were also explored.
Positive FHP associated with academic PA difficulties and importantly interacted with parental SES to moderate social PA during childhood (interaction p = 0.024). Positive FHP and parental SES did not predict differences in AAO. Nevertheless, an earlier AAO was observed among cases with worse social PA in childhood (β = −0.20; p = 0.005) and early adolescence (β = −0.19; p = 0.007). Further, confirming evidence emerged for an association between deficient childhood social PA and poor treatment response (p = 0.04).
Familial risk for psychosis may interact with parental socioeconomic position influencing social PA in childhood. In addition, this study supports the link between social PA deviations, early psychosis onset, and treatment resistance, which highlights premorbid social functioning as a promising clinical indicator.
Anxiety and Depression have often been associated in literaure, with the course of the Inflammatory Bowel Diseases(IBD):Crohn's Disease (CD) and Ulcerative Colitis (UC). The chronic character of the disease influences Quality of Life (QoL) of affected patients.
To measure Anxiety, Depression and Qol in IBD patients through psychometric tools and correlate these results with the presence or absence of the inducible form of Heat Shock Protein 70 (HSP70i) in the histologic examination of the same patients. The HSPs are cellular proteins with ubiquitus presence in humans, known to exert cytoprotecive functions when induced under conditions of cellular stress ( heat, hypoxia, etc as well as psychophysiological stress).
The study was conducted between 2005 and 2008 in two general state hospitals in the broader area of Athens, Greece.
59 IBD patients hospitalized for the endoscopic investigation of a possible relapse of their disease participated in the study(37 UC, 21 CD, 1 Intermediate Colitis).
A cross-sectional study was conducted through administration of the inventories and the comparison of their values with the presence of HSP70i in the histologic examination of each patient.
b. Zung Depression Scale;
c. STAI (State Trait Anxiety Inventory);
d. Нospital Anxiety Depression Scale;
e. SPA-810 Antigen for HSP70i (Stressgen, Canada).
The X2 distribution for nominal data showed that the presence of the inducible form of HSP70 in the lymphoid tissue, the neutrophiles and the monocytes of IBD patients’ histologic examination is not the same (not homogeneous) regarding depression, anxiety and quality of life, suggesting its possible psychosomatic character (X2>6.635,d.f.=1,p< 0.01).
Early childhood aggressive behaviour is a predictor of future violence. Therefore, identifying risk factors for children’s aggressive behaviour is important in understanding underlying mechanisms. Maternal postpartum depression is a known risk factor. However, little research has focused on the influence of paternal behaviour on early childhood aggression and its interaction with maternal postpartum depression.
This study was performed in two cohorts: the Fathers Project, in the United Kingdom (n = 143) and the Generation R Study, in The Netherlands (n = 549). In both cohorts, we related paternal antisocial personality (ASP) traits and maternal postpartum depressive (PPD) symptoms to childhood aggressive behaviour at age two (Fathers Project) and age three (Generation R Study). We additionally tested whether the presence of paternal ASP traits increased the association between maternal PPD–symptoms and early childhood aggression.
The association between paternal ASP traits and early childhood aggressive behaviour, corrected for maternal PPD-symptoms, was similar in magnitude between the cohorts (Fathers Project: standardized β = 0.12, p = 0.146; Generation R: β = 0.14, p = 0.001), although the association was not statistically significant in the Fathers Project. Strikingly, and in contrast to our expectations, there was evidence of a negative interaction between paternal ASP traits and maternal PPD-symptoms on childhood aggressive behaviour (Fathers Project: β = −0.20, p = 0.020; Generation R: β = −0.09, p = 0.043) in both studies. This meant that with higher levels of paternal ASP traits the association between maternal PPD-symptoms and childhood aggressive behaviour was less and vice versa.
Our findings stress the importance of including both maternal and paternal psychopathology in future studies and interventions focusing on early childhood aggressive behaviour.
According to the EU 28/2009 directive, member states are mandated to substitute 10% of fossil fuels used in transportation with biofuels by the year 2020. Bioethanol production is expected to contribute significantly towards fulfilling Greece's obligations. First-generation bioethanol, produced from amylaceous and sugar crops, is the most important biofuel globally. Maize (Zea mays L.) is the main feedstock for production worldwide, while sweet sorghum (Sorghum bicolor L. Moench), although a promising raw material source, has not yet enjoyed substantial commercial exploitation due to the high seasonality of the crop. Sustainability criteria set by the EU constitute a key factor in the characterization and future use of biofuels. A 3-year study including 20 maize and 4 sweet sorghum varieties was conducted in order to compare these two crops in terms of emitted greenhouse gases (GHG) during the cultivation phase as well as regarding emission savings by substituting bioethanol for petrol/gasoline. Both crops demonstrated promising bioethanol yields reaching 5235·7 and 6443·7 l/ha/yr for maize and sweet sorghum, respectively, and showed that they could be employed towards first-generation bioethanol production in Greece. Sweet sorghum varieties produced higher bioethanol yields per hectare coupled with lower emissions during the cultivation phase and better overall GHG savings compared to maize.
Sunflower (Helianthus annuus L.) and rapeseed (Brassica napus L.) are considered as the most suitable crops for biodiesel production in the Mediterranean basin. Soybean (Glycine max L.) could also be used, under certain conditions. In Greece, the farming practice adopted in each region varies significantly, leading to significant differences in the levels of emitted greenhouse gases (GHG). Greenhouse gas emissions were estimated during the cultivation phase as grams of carbon dioxide equivalents (g CO2e) per megajoule (MJ), followed by emission savings (%) estimation when fossil fuels are replaced by biodiesel. Crop and region comparisons provided important information towards promoting sustainability. Overall, sunflower demonstrated the lowest average emissions, 53·8 g CO2e/MJ, followed by rapeseed and soybean. Furthermore, rapeseed achieved the lowest emission saving level required by European legislation in most cases studied, with an average value of 37%. Irrigation and nitrogen fertilization were the operations mostly contributing to the total quantity of GHG emissions. More specifically, the highest GHG emissions were found for soybean irrigation (34%) and rapeseed nitrogen fertilization (68%).
We report the synthesis of photoreactive and light-emitting liquid crystals which can be patterned photolithographically to form polymer networks for use in organic light-emitting diodes. The resolution capability of the photopatterning is investigated using a phase mask of period one micron to spatially modulate the irradiance of ultraviolet light incident to the monomer thin film. A surface relief grating of the same period and depth 85 nm is formed on exposure and washing. An OLED incorporating a novel green light-emitting liquid-crystal has a luminous efficiency of 4.3 lm W-1 at 100 cd m-2 and gives a luminance of 990 cd m-2 at an operating voltage of 10 V.
