Several theoretical models have been occasionally proposed to account for the involvement of psychological factors in cancer genesis. Family environment and relations as well as certain personality traits were correlated to cancer onset. However, little is known in the case of acute leukemia. The present study examined family environment, state-trait anxiety, hostility and the direction of hostility as well as alexithymia in 41 acute leukemia patients and their first degree relatives (70). In accordance with previous findings, the present results showed that family cohesion, conflict and organization as well as guilt, state anxiety and alexithymia were significant risk factors for the development of the disease.

Antioxidant intake changes have been implicated with the increase in asthma and allergies outcomes, but no clear association has been revealed. In this cross sectional study, the overall effect of antioxidants on asthma and allergic diseases was studied. Data from the cohorts of the phase II ISAAC survey (2023 children 9-10 years old) in two metropolitan Greek cities were analysed. Using a semi-quantitative food frequency questionnaire, an Antioxidant Eating Index (AEI, range 0-6) was created with the pro-antioxidant (vegetables, fruits, fresh juice, fish) and the non-antioxidant (meat, burgers) food intake and was evaluated with allergic diseases. Higher values of the score suggest closer to an "antioxidant" and lesser to a "saturated fatty" diet. Prevalence of lifetime and current asthma, current rhinitis and sensitisation were higher in Thessaloniki compared to Athens. The AEI score of the entire cohort was 4.2±1.2 (median 4.0) and was higher in Athens compare...

Glutathione sulfur transferases (GSTs) is a group of enzymes involved in the detoxification process of carcinogens and other substances. The genes encoding isoenzymes M1 and T1 are polymorphic in humans and the phenotypic absence of enzyme activity (null genotype) may have an effect on the risk of chronic lymphoblastic leukemia (CLL). Our purpose was to examine whether the GSTM1 and GSTT1 homozygous null genotypes altered the risk of CLL. DNA was extracted from the peripheral blood of 27 patients with CLL and 147 cancer-free controls; both groups originated from a defined population (residents of the Ioannina region, northwestern Greece) and were similar with regard to mean age, race and sex; GSTM1 and GSTT1 were simultaneously analyzed by a multiplex polymerase chain reaction (PCR) method and Fisher's exact test was used for comparisons between the two groups. A significantly increased incidence of the GSTM1 null genotype was found in the group of patients compared to the controls (74.07 versus 34.69%, P = 0.0002). Additionally, the incidence of the GSTT1 null genotype was comparable in patients and controls (25.92 versus 10.20%, P = 0.05). The frequency of the combined GSTM1 null/T1 null genotype was significantly different between patients and controls (14.81 versus 2.04%, P = 0.012). However, there was no relationship between the advanced stage of the disease and the GSTs status. Individuals with the GSTM1 and GSTT1 null genotypes may have enhanced susceptibility to CLL.

Background: Allergic rhinitis (AR), an IgE mediated inflammatory disease, significantly impacts quality of life of a considerable proportion of the general population. Omalizumab, a humanized monoclonal antibody against IgE, has been evaluated for both seasonal and perennial AR. We aimed to assess the efficacy and safety of omalizumab in randomized controlled trials (RCTs) in inadequately controlled AR. Methods: We conducted a systematic literature search of RCTs evaluating the safety and efficacy of omalizumab in AR. We synthesized evidence for clinical improvement of AR symptoms, quality of life, reduction of the use of rescue medication, and adverse events. Results: The systematic search returned 289 articles, of which 12 RCTs were eligible for data extraction and meta-analysis. Omalizumab reduced the Daily Nasal Symptom Severity Score (DNSSS) by a summary standardized mean difference of -0.41 points with large heterogeneity; omalizumab significantly reduced the DNSSS both in the...
