Sleep Disturbances and Suicidality in Posttraumatic Stress Disorder: An Overview of the Literature

A causal relationship between sleep disturbances and suicidal behavior has been previously reported. Insomnia and nightmares are considered as hallmarks of posttraumatic stress disorder (PTSD). In addition, patients with PTSD have an increased risk for suicidality. The present article gives an overview about the existing literature on the relationship between sleep disturbances and suicidality in the context of PTSD. It aims to demonstrate that diagnosing and treating sleep problems as still underestimated target symptoms may provide preventive strategies with respect to suicidality. However, heterogeneous study designs, different samples and diverse outcome parameters hinder a direct comparison of studies and a causal relationship cannot be shown. More research is necessary to clarify this complex relationship and to tackle the value of treatment of sleep disturbances for suicide prevention in PTSD

Основной целью настоящей работы является определение возможности применения анализа добычи для получения параметров скважины и пласта, как дополнения гидродинамическим исследованиям на неустановившихся режимах фильтрации. В процессе работы в ПК Topaze был произведен анализ добычи нескольких скважин нефтяного месторождения "ХХХ", определены параметры работы системы "скважина – пласт", сделано сравнение полученных результатов адаптации с имеющимися характеристиками объектов, и на основе опытов выдано заключение о возможности применения данного исследования как альтернативы стандартным ГДИС.The main purpose of this paper is to determine the feasibility of applying Production Analysis to obtain well and reservoir parameters, as a supplement to hydrodynamic studies on unsteady filtration regimes. During the work in the Kappa Topaze PC, the Production Analysis of several wells of the "XXX" oil field was made, the parameters of the well-to-layer system were determined, the obtained adaptation results were compared with the available characteristics of the objects. On the basis of the experiments, a conclusion was made about the possibility of using this study as alternatives to standard well tests

Влияние способа обработки поверхности на сорбцию водорода титановым сплавом ВТ1-0

Объектом исследований являлся титановый сплав ВТ1-0 с различным состоянием поверхности. С помощью автоматизированного комплекса Gas Reaction Controller LP было определено влияние состояния поверхности на взаимодействие водорода с титановым сплавом.

Prevalence and psychopathological characteristics of depression in consecutive otorhinolaryngologic inpatients

<p>Abstract</p> <p>Background</p> <p>High prevalence of depression has been reported in otorhinolaryngologic patients (ORL). However, studies using a semi-structured interview to determine the prevalence of depression in ORL are lacking. Therefore the present study sought to determine the depression prevalence in ORL applying a semi-structured diagnostic interview and to further characterize the pathopsychological and demographic characteristics of depression in these patients.</p> <p>Methods</p> <p>One-hundred inpatients of the otorhinolaryngologic department of a German university hospital participated voluntarily (age M = 38.8 years, SD = 13.9; 38.0% female). Depression was assessed using a clinical interview in which the International Diagnostic Checklist for depression (IDCL) was applied. Patients completed the Brief Symptom Inventory (BSI) which constitutes three composite scores and nine symptom scales and the Beck Depression Inventory (BDI). Multivariate analyses of variance, correlations and effect sizes were conducted.</p> <p>Results</p> <p>A prevalence of depression of 21.0% was determined, 38.0% of the depressed patients were female. Depressed patients showed higher scores on the BSI-scales "interpersonal sensitivity", "depression", "anxiety", "phobic anxiety" and "psychoticism" with medium effect sizes.</p> <p>Conclusions</p> <p>High prevalence of depression was found which is in accordance with results of prior studies. Depressed patients showed higher psychological distress as compared to non-depressed patients. The results call for carrying on in engaging in depression research and routine depression screening in ORL.</p

Mismatch negativity generation in the human 5HT2A agonist and NMDA antagonist model of psychosis

RATIONALE: Many studies have reported deficits of mismatch negativity (MMN) in schizophrenic patients. Pharmacological challenges with hallucinogens in healthy humans are used as models for psychotic states. Previous studies reported a significant reduction of MMN after ketamine (N-methyl-D-aspartate acid [NMDA] antagonist model) but not after psilocybin (5HT2A agonist model). OBJECTIVES: The aim of the present study was to directly compare the two models of psychosis using an intraindividual crossover design. MATERIALS AND METHODS: Fifteen healthy subjects participated in a randomized, double-blind, crossover study with a low and a high dose of the 5HT2A agonist dimethyltryptamine (DMT) and the NMDA antagonist S-ketamine. During electroencephalographic recording, the subjects were performing the AX-version of a continuous performance test (AX-CPT). A source analysis of MMN was performed on the basis of a four-source model of MMN generation. RESULTS: Nine subjects completed both experimental days with the two doses of both drugs. Overall, we found blunted MMN and performance deficits in the AX-CPT after both drugs. However, the reduction in MMN activity was overall more pronounced after S-ketamine intake, and only S-ketamine had a significant impact on the frontal source of MMN. CONCLUSIONS: The NDMA antagonist model and the 5HT2A agonist model of psychosis display distinct neurocognitive profiles. These findings are in line with the view of the two classes of hallucinogens modeling different aspects of psychosis
