Immunohematological Parameters of Ectothermal Amphibians of the Fauna of the Middle Urals: Siberian Salamander Salamandrella Keyserlingii Dybovsky, 1870 (Caudata) and Lake Frog Pelophylax Ridibundus Pallas, 1771 (Anura).

A comparative analysis of hematological parameters was for the first time performed in two ectothermal amphibians of the Middle Ural fauna, the Siberian salamander Salamandrella keyserlingii and lake frog Pelophylax ridibundиs. Species specificity of immune defense was demonstrated with respect to granulocyte and agranulocyte counts (p < 0.001). A high lymphocyte content (73.3-76.1%) of provides for the activation of acquired adaptive immunity mechanisms in the thermophilic lake frog. The Siberian salamander is adapted to low negative temperatures and has a set of nonspecific leukocytes (39.3-44.4%). Innate immunity is better developed in the Siberian salamander compared with the lake frog.

Amino Acid Spectrum in the Blood of the Endemic and Invasive Amphibian Species in the Fauna of the Ural.

For the first time, the results of a comparative analysis of free amino acids in the blood plasma of amphibians of the Ural fauna are presented: an endemic species (Siberian salamander (Salamandrella keyserlingii Dybovsky, 1870)) and an invasive species (marsh frog (Pelophylax ridibundus Pallas, 1771)). The species diversity of adaptive strategies of thermoresistant amphibionts both to negative and positive temperatures is shown.

Hidradenitis suppurativa and schizophrenia: a nationwide cohort study.

BACKGROUND: Hidradenitis suppurativa (HS) is a chronic, debilitating, dermatological disease that causes substantial psychosocial impediments with increased suicidal risk. Yet data on psychiatric comorbidity in HS have not been sufficiently elucidated in population-based studies. The current study sought to investigate the association between HS and schizophrenia, a major psychiatric disease, in a nationwide population-based study in Israel. METHODS: Data mining was performed on the database of Clalit Health Services (CHS), the largest managed healthcare company in Israel. Patients diagnosed with HS (n = 4191) were examined and compared to age- and sex-matched controls (n = 20 941). The association between HS and schizophrenia was assessed via multivariate binary logistic regression, adjusting for demographic factors and smoking status. RESULTS: The analysis revealed a tenfold increase in the prevalence of schizophrenia in HS patients compared to controls (1.4% and 0.4%, respectively, P < 0.001). In multivariate analysis, HS was found to be associated with schizophrenia (OR 1.44, 95% CI 1.01-2.07, P < 0.05). CONCLUSIONS: Hidradenitis suppurativa is associated with schizophrenia. Screening for severe mental illness during the assessment of patients with HS is of great importance, as comorbid psychiatric disorders may affect treatment outcomes.
