Sichtbare Entfremdung: Der Blick auf Russland im Sicherheitsradar 2022
Der "Security Radar 2022: Navigating the Disarray of European Security" ist eine Studie der Friedrich-Ebert-Stiftung, die auf einer repräsentativen Bevölkerungsumfrage in 14 OSZE-Staaten basiert und kurz vor Kriegsausbruch erschienen ist. Die "Unordnung" in der europäischen Sicherheit ist in dieser Analyse an vielen Dimensionen und Fragen erkennbar. Im Folgenden sollen vor allem vier relevante Aspekte aus der Studie diskutiert werden, um einen Überblick über die sicherheitspolitischen Einstellungen in Russland vor Kriegsausbruch zu bekommen: Zugehörigkeit zu Europa, Rückgang der Wahrnehmung von Interdependenzen, die Perzeption des Konflikts und Statusunzufriedenheit. Denn auch in autokratischen Systemen kann die politische Führung nicht losgelöst von der Öffentlichkeit solche schicksalhafte Entscheidungen treffen
Diagnostic Clinical and Laboratory Findings in Response to Predetermining Bacterial Pathogen: Data from the Meningitis Registry
BACKGROUND: Childhood meningitis continues to be an important cause of mortality in many countries. The search for rapid diagnosis of acute bacterial meningitis has lead to the further exploration of prognostic factors. This study was scheduled in an attempt to analyze various clinical symptoms as well as rapid laboratory results and provide an algorithm for the prediction of specific bacterial aetiology of childhood bacterial meningitis. METHODOLOGY AND PRINCIPAL FINDINGS: During the 32 year period, 2477 cases of probable bacterial meningitis (BM) were collected from the Meningitis Registry (MR). Analysis was performed on a total of 1331 confirmed bacterial meningitis cases of patients aged 1 month to 14 years. Data was analysed using EPI INFO (version 3.4.3-CDC-Atlanta) and SPSS (version 15.0-Chicago) software. Statistically significant (p<0.05) variables were included in a conditional backward logistic regression model. A total of 838 (63.0%) attributed to Neisseria meningitidis, 252 (18.9%) to Haemophilus influenzae, 186 (14.0%) to Streptococcus pneumoniae and 55 (4.1%) due to other bacteria. For the diagnosis of Meningococcal Meningitis, the most significant group of diagnostic criteria identified included haemorrhagic rash (OR 22.36), absence of seizures (OR 2.51), headache (OR 1.83) and negative gram stain result (OR 1.55) with a Positive Predictive Value (PPV) of 96.4% (95%CI 87.7-99.6). For the diagnosis of Streptococcus pneumoniae, the most significant group of diagnostic criteria identified included absence of haemorrhagic rash (OR 13.62), positive gram stain (OR 2.10), coma (OR 3.11), seizures (OR 3.81) and peripheral WBC > or = 15000/microL (OR 2.19) with a PPV of 77.8% (95%CI 40.0-97.2). For the diagnosis of Haemophilus influenzae, the most significant group of diagnostic criteria included, absence of haemorrhagic rash (OR 13.61), age > or = 1 year (OR 2.04), absence of headache (OR 3.01), CSF Glu < 40 mg/dL (OR 3.62) and peripheral WBC < 15,000/microL (OR 1.74) with a PPV of 58.5% (95%CI 42.1-73.7). CONCLUSIONS: The use of clinical and laboratory predictors for the assessment of the causative bacterial pathogen rather than just for predicting outcome of mortality seems to be a useful tool in the clinical management and specific treatment of BM. These findings should be further explored and studied
Prognostic factors related to sequelae in childhood bacterial meningitis: Data from a Greek meningitis registry
<p>Abstract</p> <p>Background</p> <p>Bacterial meningitis (BM) is a life-threatening disease, often related with serious complications and sequelae. Infants and children who survive bacterial meningitis often suffer neurological and other sequelae.</p> <p>Methods</p> <p>A total of 2,477 patients aged 1 month to 14 years old hospitalized in a Children's Hospital in Greece diagnosed with acute bacterial meningitis were collected through a Meningitis Registry, from 1974 to 2005. Clinical, laboratory and other parameters (sex, age, pathogen, duration of symptoms before and after admission) were evaluated through univariate and multivariate analysis with regard to sequelae. Analysis of acute complications were also studied but not included in the final model.</p> <p>Results</p> <p>The rate of acute complications (arthritis and/or subdural effusion) was estimated at 6.8% (152 out of 2,251 patients, 95%CI 5.8-7.9) while the rate of sequelae (severe hearing loss, ventriculitis, hydrocephalus or seizure disorder) among survivors was estimated at 3.3% (73 out of 2,207 patients, 95%CI 2.6-4.2). Risk factors on admission associated with sequelae included seizures, absence of hemorrhagic rash, low CSF glucose, high CSF protein and the etiology of meningitis. A combination of significant prognostic factors including presence of seizures, low CSF glucose, high CSF protein, positive blood culture and absence of petechiae on admission presented an absolute risk of sequelae of 41.7% (95%CI 15.2-72.3).</p> <p>Conclusions</p> <p>A combination of prognostic factors of sequelae in childhood BM may be of value in selecting patients for more intensive therapy and in identifying possible candidates for new treatment strategies.</p
Immunogenicity of the BNT162b2 mRNA Covid-19 vaccine in elderly people over 85 years of age in Greece: the GREVAXIMO study.
BACKGROUND
Elderly people aged over 85 years were among the first groups to receive the BNT162b2 mRNA Covid-19 vaccine in Greece according to the national priority assignment policy.
AIM
The aim of this study was to provide useful insight into the antibody generation taking place post-immunization in elderly individuals aged over 85.
METHODS
In the first phase of our study, antibody levels were monitored in a total of 400 participants, while our final sample consisted of 297 subjects. Humoral immune responses were recorded in 69.75% (95% CI 65.25-74.25) of vaccinees post-first dose and in 98.99% (95% CI 97.85-100) post-second dose.
RESULTS
Overall, a remarkable 40-fold change in IgG levels was observed between the two doses. Subjects displaying low antibody levels after the first dose had significantly higher IgG fold changes than vaccinees whose initial antibody levels were high.
CONCLUSION
Taken together, our findings highlighted the high fold change (41.18) recorded in the titers of neutralizing antibodies after the second dose suggesting the need for its timely administration to elderly individuals
Prevalence and Risk Factors of Overweight and Obesity among Adolescents and Their Parents in Central Greece (FETA Project)
The increasing obesity trend in adolescence is a public health concern. The initial phase of Feeding Exercise Trial in Adolescents (FETA) aimed in investigating the prevalence of overweight and obesity in adolescents and their parents and in identifying associated factors among parents’ and adolescents’ demographics, eating habits, and parental style. The sample consisted of 816 adolescents, aged 12–18 years old, and their parents from 17 middle and high schools in Larissa, central Greece. During school visits, anthropometric measurements were performed along with examination of blood pressure. The students completed the study tool that comprised of demographics and the modified versions of Parental Authority Questionnaire (PAQ), the Parent-Initiated Motivational Climate Questionnaire-2 (PIMCQ-2) and the Family Eating and Activity Habits Questionnaire (FEAHQ). Their parents completed a questionnaire with demographics, anthropometrics and FEAHQ. Normal Body Mass Index was found in 75.2% of the adolescents, 2.6% of the adolescents were underweight, 18% overweight and 4.2% obese. Regarding the parents, 76.3% of the fathers and 39.2% of the mothers were overweight or obese. The logistic regression analysis revealed that, overweight or obesity in adolescence was associated with gender (boy), maternal overweight or obesity, lower maternal educational level, eating without feeling hungry, eating in rooms other than kitchen and having a father that motivates by worrying about failing. A significant proportion of adolescents and their parents are overweight or obese. Future interventions should focus both on the parents and children, taking into account the role of parental authority style, in preventing adolescents’ obesity
Knowledge, Attitudes, and Practices about the Prevention of Mosquito Bites and Zika Virus Disease in Pregnant Women in Greece
A survey among 573 pregnant women in Greece was conducted through self-completion of a questionnaire in July 2016. Traveling abroad the last six months was declared by 10.5% and 13.0% of pregnant women and their male sex partners, respectively, while 77.4% (441/570) had heard about Zika virus disease (ZVD). A lack of knowledge about sexual transmission of ZVD was identified in 63.3% of pregnant women, and 24.1% of responders did not know the risks to the fetus and baby. Approximately 73% of responders believed that the mosquito bites can affect their fetus and baby and 18% did not take measures to prevent mosquito bites routinely. Multivariable logistic regression models showed that traveling abroad the last six months by pregnant women correlated with correctly answering the question about the transmission of ZVD through bites of infected mosquitoes (Odds Ratio, OR = 10.47, 95% CI = 1.11–98.41). Traveling abroad with a male sex partner over the last six months correlated (OR = 2.05, 95% CI = 0.99–4.23) with responding correctly to the four key questions about the transmission of ZVD through mosquito bites, the risk of microcephaly, and the risks of traveling to the affected countries. A score of ≥5 for the nine responses given to questions of knowledge and attitudes was associated with a Bachelor of Science degree (OR = 1.54, 95% CI = 1.09–2.18), antenatal care at a public hospital (OR = 2.26, 95% CI = 1.28–3.98), being a civil servant as occupation (OR = 1.96, 95% CI = 1.10–3.48), and having gotten information about ZVD from the public health sector (OR = 2.04, 95% CI = 1.05–3.98). In conclusion, we found considerable knowledge gaps related to ZVD among Greek pregnant women. These study results are useful in targeting pregnant women for the prevention of potential Zika virus infections
<i>Legionella</i> Colonization of Hotel Water Systems in Touristic Places of Greece: Association with System Characteristics and Physicochemical Parameters
This study aimed to assess the colonization of hotel water systems in central Greece and Corfu by Legionella, and to investigate the association between physicochemical parameters and Legionella colonization. Standardized hygiene inspection was conducted in 51 hotels, and 556 water samples were analyzed for Legionella spp. Free chlorine concentration, pH, hardness, conductivity, and trace metals were defined in cold water samples. The results of inspections and chemical analyses were associated with the microbiological results using univariate and logistic regression analysis. According to the score of the checklist used for the inspections, 17.6% of the hotels were classified as satisfactory, 15.7% as adequate, and 66.7% as unsatisfactory. Moreover, 74.5% of the hotels were colonized by Legionella spp. and 31.4% required remedial measures according to the European guidelines. Legionella spp. were isolated in 28% of the samples. Unsatisfactory results of inspections were associated with Legionella presence (relative risk (RR) = 7.67, p-value = 0.043). In hot-water systems, <50 °C temperatures increased the risk of Legionella colonization (RR = 5.36, p-value < 0.001). In cold-water systems, free chlorine concentration <0.375 mg/L (odds ratio (OR) = 9.76, p-value = 0.001), pH ≥ 7.45 (OR = 4.05, p-value = 0.007), and hardness ≥321 mgCaCO3/L (OR = 5.63, p-value = 0.003) increased the risk, whereas copper pipes demonstrated a protective role (OR = 0.29, p-value = 0.0024). The majority of the hotels inspected were colonized with Legionella. Supplementary monitoring of the risk factors that were identified should be considered
A Case-Control Study on the Risk Factors for Meningococcal Disease among Children in Greece.
The aim of this study was to identify environmental or genetic risk factors that are associated with invasive meningococcal disease (IMD) in children in Greece.A case-control study was performed in 133 children (44 cases and 89 controls) aged between 0-14 years, who were hospitalized in a children's hospital in Athens. Demographics and possible risk factors were collected by the use of a structured questionnaire. To investigate the association of mannose binding lectin (MBL) with IMD, a frequency analysis of the haplotypes of the MBL2 gene and quantitative measurement of MBL serum protein levels were performed using Nanogen NanoChipR 400 technology and immuno-enzyme techniques, respectively.The multivariate analysis revealed that changes in a child's life setting (relocation or vacation, OR = 7.16), paternal smoking (OR = 4.51), upper respiratory tract infection within the previous month (OR = 3.04) and the density of people in the house/100m2 (OR = 3.16), were independent risk factors associated with IMD. Overall 18.8% of patients had a MBL2 genotype with low functionality compared to 10.1% of healthy controls, but this was not statistically significant (p = 0.189).Prevention strategies aimed at reducing parental smoking and other risk factors identified in this study could decrease the risk of IMD among children in Greece
Prevalence and determinants of current cigarette smoking and secondhand smoking among Greek adolescents: the Global Youth Tobacco Survey (GYTS) 2013 study
Objectives Smoking prevalence in Greece is considered high within the
European Union and the collection of evidence on tobacco use among
adolescents is of vital importance in order to develop effective smoking
prevention and cessation programmes.
Design Cross-sectional.
Setting Greece.
Primary and secondary outcome measures Global Youth Tobacco Survey
(GYTS) is a national representative, paper-and-pencil, cross-sectional,
school-based study of students at ages 13-15 years. The survey employed
a multistage cluster sample design with schools selected proportional to
enrolment size. Finally, 4618/5127 students aged 13-15 years
participated in the survey. The school response rate was 98.1%, the
student response rate was 90.1% and the overall response rate was
88.4%.
Results The prevalence of current cigarette smoking was estimated at
10.1% (10.4% in GYTS 2005) and of exposure to secondhand smoking in
public places at 67.4% (94.1% in GYTS 2005). The vast majority of the
adolescents (82.1%) supported the banning of smoking inside enclosed
public places. Most of the current smokers (90.8%) were not
prevented/refused purchase because of their age according to existing
law. Multivariate analysis showed that peer influence (OR=48.32; 95% CI
36.2 to 64.48), pocket money (OR=2.63; 95% CI 1.28 to 3.41), increasing
age (OR=2.35; 95% CI 1.63 to 3.39) and low educational level of father
(OR=2.82; 95% CI 1.7 to 4.68) were risk factors independently
associated with current cigarette smoking.
Conclusions Despite the existence of strict laws related to tobacco
control, exposure to secondhand smoking among Greek students remained
high even when compared with GYTS in 2005. This is likely a result of
weak enforcement, what is really missing is the enforcement of the
related legislation
