Is Atorvastatin Associated with New Onset Diabetes or Deterioration of Glycemic Control? Systematic Review Using Data from 1.9 Million Patients.

BACKGROUND: Current evidence indicates that statins increase the risk of new onset diabetes mellitus (NOD) and also deteriorate the glycemic control in patients with known diabetes mellitus (DM) after high-dose statin therapy. AIMS: The aim of this review was to explore the effect of atorvastatin in causing NOD or deteriorating glycemic control in patients with DM. METHODS: Two independent reviewers conducted the literature search, through PubMed database searching for articles published in English until April 2015, and only primary studies were included. RESULTS: Of the 919 articles identified in our original search, 33 met the criteria for this review encompassing 1,951,113 participants. Twenty articles examined dysregulation of DM due to atorvastatin. Half of them showed that there was no significant change in glycemic control in patients treated with atorvastatin. Other studies showed that fasting plasma glucose and HbA1c levels were increased by atorvastatin. Thirteen articles examined if atorvastatin causes NOD. The majority of these articles showed that patients who used atorvastatin had a higher dose-dependent risk of developing NOD. CONCLUSION: This systematic review suggests that there is an association between atorvastatin treatment and NOD. Moreover, it showed that atorvastatin in high dose causes worsening of the glycemic control in patients with DM

Humor appreciation of captionless cartoons in obsessive-compulsive disorder

Background: It seems that the core neural regions and cognitive processes implicated in obsessive-compulsive disorder (OCD) pathophysiology may overlap with those involved in humor appreciation. However, to date, there have been no studies that have explored humor appreciation in OCD. The purpose of the present work was to investigate humor appreciation in a group of patients with OCD.Methods: We examined 25 patients with OCD and 25 healthy controls, matched by age, education, and gender. We administered Penn's Humor Appreciation Test (PHAT), a computerized test comprising captionless cartoons by Mordillo. Each set of stimuli consisted of two almost identical drawings, one of which was funny due to the alteration of a detail in the cartoon, whereas the other was not funny. Severity of psychopathology was evaluated with the Yale-Brown Obsessive Compulsive Scale (Y-BOCS).Results: No significant effect for group, gender or group × gender interaction was found on the PHAT scores. In OCD patients, humor appreciation was not significantly associated with age of onset, duration of illness, and obsessions, but correlated significantly with compulsions.Conclusions: Humor appreciation, based on captionless cartoons in OCD, does not seem to be deficient compared to healthy subjects but may be related to illness characteristics. © 2011 Bozikas et al; licensee BioMed Central Ltd

Molecular assessment of Podarcis sicula populations in Britain, Greece and Turkey reinforces a multiple-origin invasion pattern in this species

Biological invasions are a challenge to conservation and constitute a threat to biodiversity worldwide. The Italian wall lizard Podarcis sicula has been widely introduced, and seems capable of adapting to most of the regions where it is established and to impact on native biota. Here we construct a phylogenetic framework to assess the origin of the introduced populations in the United Kingdom, Greece and Turkey comparing cytochrome-b gene sequences of lizards from five locations to published sequences from the native range and other non-native locations. The results support an origin from central Italy for the United Kingdom population, from the Adriatic region for the Greek population and from Calabria for the population from Turkey. These results emphasise the multiple-source pattern of introduction of this species identified in previous studies. The improvement in the knowledge of the origin and pathways by which invaders arrive in new areas, as well as the monitoring of their populations, are crucial for successful strategies to deal with exotic species

FOXN1 forms higher-order nuclear condensates displaced by mutations causing immunodeficiency

The transcription factor FOXN1 is a master regulator of thymic epithelial cell (TEC) development and function. Here, we demonstrate that FOXN1 expression is differentially regulated during organogenesis and participates in multimolecular nuclear condensates essential for the factor’s transcriptional activity. FOXN1’s C-terminal sequence regulates the diffusion velocity within these aggregates and modulates the binding to proximal gene regulatory regions. These dynamics are altered in a patient with a mutant FOXN1 that is modified in its C-terminal sequence. This mutant is transcriptionally inactive and acts as a dominant negative factor displacing wild-type FOXN1 from condensates and causing athymia and severe lymphopenia in heterozygotes. Expression of the mutated mouse ortholog selectively impairs mouse TEC differentiation, revealing a gene dose dependency for individual TEC subtypes. We have therefore identified the cause for a primary immunodeficiency disease and determined the mechanism by which this FOXN1 gain-of-function mutant mediates its dominant negative effect

The additional value of patient-reported health status in predicting 1-year mortality after invasive coronary procedures: A report from the Euro Heart Survey on Coronary Revascularisation

Objective: Self-perceived health status may be helpful in identifying patients at high risk for adverse outcomes. The Euro Heart Survey on Coronary Revascularization (EHS-CR) provided an opportunity to explore whether impaired health status was a predictor of 1-year mortality in patients with coronary artery disease (CAD) undergoing angiographic procedures. Methods: Data from the EHS-CR that included 5619 patients from 31 member countries of the European Society of Cardiology were used. Inclusion criteria for the current study were completion of a self-report measure of health status, the EuroQol Questionnaire (EQ-5D) at discharge and information on 1-year follow-up, resulting in a study population of 3786 patients. Results: The 1-year mortality was 3.2% (n = 120). Survivors reported fewer problems on the five dimensions of the EQ-5D as compared with non-survivors. A broad range of potential confounders were adjusted for, which reached a p<0.10 in the unadjusted analyses. In the adjusted analyses, problems with self-care (OR 3.45; 95% CI 2.14 to 5.59) and a low rating (≤ 60) on health status (OR 2.41; 95% CI 1.47 to 3.94) were the most powerful independent predictors of mortality, among the 22 clinical variables included in the analysis. Furthermore, patients who reported no problems on all five dimensions had significantly lower 1-year mortality rates (OR 0.47; 95% CI 0.28 to 0.81). Conclusions: This analysis shows that impaired health status is associated with a 2-3-fold increased risk of all-cause mortality in patients with CAD, independent of other conventional risk factors. These results highlight the importance of including patients' subjective experience of their own health status in the evaluation strategy to optimise risk stratification and management in clinical practice

Temporal responses of soil invertebrate communities to draught stress in two semiarid ecosystems of the Mediterranean

The soil invertebrate community of two Mediterranean ecosystems was studied on Milos Island, in the Aegean Sea: one a Mediterranean-type ecosystem and the other a dune ecosystem. Sampling of macrofauna was carried out for 19 months using pitfall traps. For mesofauna, 25 × 25 cm samples of litter were collected and processed in Berlese-Tullgern funnels. Specimens were identified to class or order level except for Coleoptera and Hymenoptera Formicidae, which were identified to family level, and the slugs, which included a number of families. Some taxa were identified to species level. Environmental data were also collected. The dominant groups were beetles, ants, and spiders. Diversity and evenness were low in spring and summer and high in autumn and winter in the dune site, and more or less at the same level throughout the year in the Mediterranean-type site. The three most common phenological patterns in both sites were a spring, a summer, and an autumn and winter peak. The composition of the fauna seemed to change along two large seasons, spring/summer vs. autumn/winter. Possible responses of the soil community to drought stress include lower diversity, especially in the dry season, short transitional periods between the dry and humid seasons, disappearance from the surface during the dry season, dispersal when favorable conditions appear, rapid development of juveniles and short life span of adults of the thermophilous species, longer development of juveniles and life span &quot;tuned&quot; to the end of the favorable season for the psychrophilous species, and horizontal movements within a site

Diet of a lacertid lizard (Podarcis milensis) in an insular dune ecosystem

This study reports on the seasonal, sex, and age differences in the diet composition of a population of the lacertid lizard Podarcis milensis inhabiting an arid sand dune on Milos Island (Aegean Archipelago, Greece). Stomach contents of 191 animals were analyzed and compared with prey availability data. The most important prey types were Hemiptera, Coleoptera (other than Tenebrionidae), spiders, and ants. Other prey items included plant material and insect larvae, both constantly consumed throughout the year. Differences in the taxonomic composition of the diet were found between males and females and between juveniles and all other classes. The greatest similarity of diet composition between the sexes and ages examined was during summer. The foraging patterns observed are discussed within the context of the specific study system: an insular, low productivity, sand dune ecosystem
