Post-traumatic stress disorder (PTSD) is a debilitating condition, which generates an extensive burden. We aimed to investigate in a huge metropolitan area, the prevalence of traumatic experiences, the development of PTSD, and its predictors.
Traumatic experiences and PTSD were assessed in 5037 adult individuals of the general population. Cross-tabulations method assessed the prevalence of traumatic events and PTSD. Logistic regression models investigated predictors of lifetime and 12-month odds of PTSD and the conditional probability of developing PTSD for specific traumas.
Lifetime and 12-month diagnoses of PTSD were found in 3.2% and 1.6% of the sample. 'Witnessing anyone being injured or killed, or unexpectedly seeing a dead body' (35,7%) and 'being mugged or threatened with a weapon' (34.0%) were the two most reported traumas. The commonest events before PTSD onset were 'sudden unexpected death of a loved one' (34.0%), 'interpersonal violence' (31.0%), and 'threats to the physical integrity of others' (25.0%). Experiences related to "interpersonal violence" presented the highest conditional probability for PTSD (range 2.2-21.2%). Being 'sexually assaulted or molested' (21.2% total; 22.3% women; 0.0% men) and being 'raped' (18.8% total; 18.4% women; 20.1% men) were the two experiences with the highest odds for PTSD. While being female was a predictor of less exposure to any event (OR=0.69), females were more prone to develop lifetime PTSD after exposure to an event (OR=2.38).
Traumatic events are frequent in the general population and a small group of traumatic events accounts for most cases of subsequent PTSD.

Suicide attempters (SA) are more vulnerable to social stress and show disturbed cortisol response in stressful conditions compared with psychiatric and healthy controls. Recent data suggest that this dysregulation might be related to impulsivity traits. However, little is known about the emotional consequences of social stress in SA exposed to stress.
The aim of our study was to evaluate the cortisol and emotional responses to social stress in patients with depression with and without suicide attempt, by taking into account impulsivity traits and depression severity.
67 adult women (41 SA and 26 affective controls (AC,i.e. without suicide attempt history)) with lifetime history of major depressive episode were included. Patients performed the Trier Social Stress Test (TSST), a well-validated social stress task. Patients provided seven saliva samples, to measure the cortisol response, and filled in questionnaires to assess psychological pain, positive and negative mood, and anxiety at different time pointy in stress conditions. Impulsivity traits might help to differentiate patients at risk of suicide who are highly sensitive to stress when depression level is low. Higher impulsiveness may increase the sensitivity to emotional distress that translates into inadequate physiological responses.There is a lack of consensus on whether routine brain magnetic resonance imaging (MRI) should be recommended as part of the initial assessment in patients with psychosis. No study so far has qualitatively assessed brain MRI in patients with early-onset psychosis (EOP), in whom neurodevelopmental factors may play a stronger role. We aimed to determine the prevalence of brain MRI findings in patients with EOP compared to healthy controls, and assess whether these findings were clinically relevant. Retrospective clinical chart review of all patients with EOP in whom a brain MRI scan was acquired during admission to an inpatient child and adolescent psychiatry unit during January 2013-December 2017, compared to age and biologically assigned gender matched healthy controls. Between group analyses tested differences in rates of qualitatively abnormal MRI scans and changes in clinical management as a result of radiological findings. A total of 256 individuals were included (128 patients with EOP and 128 healthy controls). Patients with EOP presented with a significantly higher rate of abnormal MRI scans relative to healthy controls (21.9% vs 11.7%, p = .030; OR = 2.11, [95% CI1.06-4.17]). Radiological findings in the EOP group triggered clinical referral for further evaluation or management more often than in the healthy control group (7.0% vs 1.6%, p = .030; OR = 4.76, [95% CI1.01-22.50]). MRI scans in youth with EOP may be characterized by an increased number of radiological abnormalities than in controls. The rates of MRI findings requiring clinical referral suggests that routine MRI acquisition may need to be considered in patients with EOP.We conducted two studies to investigate the links between perceived social support, problematic pornography use (PPU) and compulsive sexual behavior disorder (CSBD). In Study 1 (n=807, convenience sample recruited via social media) we collected preliminary data and in Study 2 (n=1526) we checked whether the results replicate in a sample representative of the Polish adult population. In both studies participants completed the Brief Pornography Screen, Compulsive Sexual Behavior Disorder Scale and Multidimensional Scale of Perceived Social Support. In Study 1 and 2, general social support was a weak protective factor against CSBD (β = -0.15 and β = -0.10) and PPU (β = -0.12 and β = -0.09 respectively, all p values ≤ .001) adjusting for gender, age, sexual orientation and relationship status. The results for three domains of social support (from friends, significant other and family), however, largely differed between the two studies. In Study 1, perceived friends' support weakly protected against PPU and CSBD symptoms. In Study 2 higher support from friends weakly predicted lower CSBD symptoms among men; and stronger family support predicted lower PPU. Support from a significant other was weakly related to lower CSBD for women in Study 1. The conducted studies provided evidence that perceived social support is a protective factor against problematic sexual behavior; however, its predictive power is limited and further studies are needed to assess the importance of various domains of social support in the development of CSBD and PPU symptoms.Cognitive function during an ECT care pathway is mainly investigated at the group level by analyzing mean cognitive test scores over time. However, there are important inter-individual differences, with some patients experiencing residual invalidating cognitive deficits. This study provides a nuanced examination of cognitive functioning during and after ECT by combining three approaches for data analysis. A cognitive test battery was assessed in seventy-three ECT-treated patients with a Major Depressive Episode (MDE) at up to five time points (baseline, immediately prior to the third session and 1 week, 3 months and 6 months after completion of the index course). Group-level changes in cognitive function were investigated using linear mixed models and individual-level changes were examined using Reliable Change Indices (RCI). L(+)-Monosodium glutamate monohydrate supplier The presence of patient subgroups with similar cognitive trajectories was explored using Latent Class Growth Analysis (LCGA). At the group level, there was a temporary deterioration in processing speed, verbal memory and retrograde amnesia during and after index course of ECT. Individual-level analyses revealed considerable variability in cognitive effects of ECT. Three patient classes with a similar cognitive trajectory could be identified, all with a rather parallel courses over time, thus mainly differing in terms of pre-ECT cognitive functioning.SelenoproteinK (SelK), an endoplasmic reticulum (ER) - resident protein, possesses the property of mediate oxidation resistance and ER - associated protein degradation (ERAD) in several tissues. Here, we found that increased SelK markedly promotes fatty acid translocase (CD36) subcellular trafficking and aggravates lipid accumulation in hepatocytes. We demonstrated that SelK is required for the assembly of COPII vesicles and accelerates transport of palmitoylated-CD36 from the ER to Golgi, thus facilitating CD36 plasma membrane distribution both in vivo and in vitro. The mechanism is that SelK increases the stability of Sar1B and triggers CD36-containing nascent COPII vesicle formation, consequently, promotes CD36 subcellular trafficking. Furthermore, we verified that the intervention of SelK SH3 binding domain can inhibit the vesicle formation and CD36 subcellular trafficking, significantly ameliorates NAFLD in mice. Collectively, our findings disclose an unexpected role of SelK in regulating NAFLD development, suggesting that targeting the SelK of hepatocytes may be a new therapeutic strategy for the treatment of NAFLD.Sulfane sulfur species such as hydropersulfides (RSSH), polysulfides (RSnR), and hydrogen polysulfides (H2Sn) are critically involved in sulfur-mediated redox signaling, but their detailed mechanisms of action need further clarification. Therefore, there is a need to develop selective and sensitive sulfane sulfur detection methods to gauge a better understanding of their functions. This review summarizes current detection methods that include cyanolysis, chemical derivatization and mass spectrometry, proteomic analysis, fluorescent probes, and resonance synchronous/Raman spectroscopic methods. The design principles, advantages, applications, and limitations of each method are discussed, along with suggested directions for future research on these methods. The development of robust detection methods for sulfane sulfur species will help to elucidate their mechanisms and functions in biological systems.Electrochemiluminescence (ECL) is a powerful electrochemical technique for the detection and quantification of molecules, both synthetic and biological in origin. Traditional ECL luminophores are based on organic or organometallic compounds, however nanoparticle-based materials offer the benefits of tuneable wavelengths and narrow emission profiles. Materials based on cadmium have been the most extensively studied for ECL nanoparticles to date. Cadmium based nanoparticles exhibit high levels of toxicity thereby impacting their suitability for mass produced sensing applications. As such, alternative materials with reduced toxicities are required. This review focuses on the innovations and applications of low toxicity semi-conductor quantum dots (SCQDs) utilised as ECL luminophores within biosensors. These materials include silver, copper, zinc, tin, silicon and germanium. This contribution presents an evaluative overview of these materials for use as ECL luminophores in terms of toxicity, tunability of emission, potential for amplification, and water dispersibility. Capacity for functionalisation and multiplexing potential are also explored.
To examine the association between comorbid mental disorders and cardiovascular disease (CVD) risk among patients with type 2 diabetes.
This retrospective cohort study was conducted using the claims data of 2,227,394 South Korean patients with type 2 diabetes. We analyzed the occurrence of CVD including myocardial infarction (MI) and ischemic stroke, CVD-specific mortality, and all-cause mortality according to comorbid mental disorders including depressive disorders, bipolar and related disorders, schizophrenia spectrum disorders, insomnia, and anxiety disorders.
Among the patients, 9.1% had a comorbid mental disorder. The adjusted hazard ratios (aHR) for MI, ischemic stroke, CVD-specific mortality, and all-cause mortality in patients with any mental disorder were 1.20 (95% CI, 1.17-1.24), 1.13 (95% CI, 1.11-1.16), 1.16 (95% CI, 1.12-1.20), and 1.21 (95% CI, 1.19-1.23), respectively. Each mental disorder increased the risk of all outcomes, particularly bipolar and related disorders and schizophrenia spectrum disorders.
