Extensive difficulties in reaching functional milestones characterize schizophrenia and related psychotic disorders. These impairments are in part explained by lower social cognitive abilities, cognitive impairment, and current psychopathology. The present study aims to model dynamic associations among social cognition, neurocognition, psychopathology, social skills, functional capacity, and functional outcomes in schizophrenia using network analysis in order to identify those factors that are most central to functioning.

The sample consisted of 408 patients with schizophrenia spectrum disorders who were drawn from the SCOPE project. Participants completed a complex battery of state-of-the-art measures of social cognition, neurocognition, and functional outcomes. Gaussian Graphical Modeling was used for estimation of the network structure. Accuracy of the network was evaluated using the Bootstrap method.

Data supported the importance of functional capacity and social skills, which are prerequisites to real - world outcomes. These variables were among the most central in the network. Social cognition was related to functional capacity, social skills, and real - world functioning. Negative symptoms were connected to functional capacity, social skills, and real - world functioning.

Predictors of functional outcomes are complexly associated with each other. Functional capacity, social - skills, working memory, negative symptoms, mentalizing, and emotion recognition were central nodes that support their importance as potential targets of personalized intervention.

However, the magnitude of the effect appears to be attenuated in first-episode populations. Furthermore, how mismatch negativity amplitudes are related to brain connectivity in this population is unclear. In this study, we used high-density EEG to record duration-deviant MMN from 22 patients with first-episode psychosis (FEP) and 23 age-matched controls (HC). Consistent with past work, we found decreased MMN amplitude in FEP over a large area of the frontal scalp. Meclofenamate Sodium molecular weight We also found decreased latency over the occipital scalp. MMN amplitude was negatively correlated with antipsychotic dose. We used Granger causality to investigate directional connectivity between frontal, midline, left, and right scalp during MMN and found reduced connectivity in FEP compared to HC and following deviant stimuli compared to standard stimuli. FEP participants with smaller decreases in connectivity from standard to deviant stimuli had worse disorganization symptoms. On the other hand, connectivity from the front of the scalp following deviant stimuli was relatively preserved in FEP compared to controls. Our results suggest that a relative imbalance of bottom-up and top-down perceptual processing is present in the early stages of psychotic disorders.

To examine the time-trends in hospitalizations and the factors associated with outcomes of hospitalizations with cocaine use disorder (CocUD).

This study used the U.S. National Inpatient Sample (NIS) data from 1998 to 2014 to examine the time-trends in hospitalization rates and the predictors of healthcare utilization (total hospital charges, discharge destination, length of hospital stay) and in-hospital mortality for CocUD-hospitalization. We used multivariable-adjusted logistic regression analyses to assess the association of patient demographics (age, sex, race/ethnicity, household income), comorbidity (Deyo-Charlson index), insurance payer (Medicare, Medicaid, private, self-pay or other), and hospital characteristics (location/teaching status; hospital bed size; and region) with outcomes with healthcare utilization and in-hospital mortality for CocUD-hospitalizations.

There were 6,454,775 weighted hospitalizations with CocUD in the U.S. 1998-2014. The population was predominantly black (38%), 45 yeociated with healthcare utilization outcomes and mortality outcomes of hospitalizations with CocUD.Intimate partner violence (IPV) is a global health problem that often results in a variety of mental health detriments, including trauma-related distress and depressive symptoms. According to the trauma literature, IPV victims may develop strong bonds with their perpetrators - a phenomenon known as identification with the aggressor (IWA) - in order to survive the abuse. Yet, this defensive reaction may endure after the abuse has ended, and may adversely affect victims' mental health. Nevertheless, research exploring these suppositions is lacking. Filling this void, this study investigated IWA in light of current versus past IPV as well as the relations between IWA, trauma-related distress, and depressive symptoms among a convenience sample of 297 women. Of them, 68 and 229 participants reported being subjected to IPV at present or in the past, respectively. Results indicated that whereas participants who reported current IPV had elevated trauma-related distress and depressive symptoms compared to participants who reported past IPV, no differences were found in IWA levels between the groups. link2 Identification with the aggressor was related to trauma-related distress and depressive symptoms. Furthermore, IWA had a unique contribution in explaining trauma-related distress and depressive symptoms above and beyond background characteristics and IPV features. The findings of the current study suggest that IWA may mirror the unique relational dynamics that characterize IPV, which continue to exist even after the abuse ends, and may be implicated in IPV survivors' psychological distress.Literature data did not show univocal evidence in discriminating which form of attachment insecurity is involved in obsessive-compulsive disorder (OCD) both anxiety and avoidance was related to OCD symptomatology. No study used the Attachment Style Questionnaire (ASQ) that allows for investigation of differentiated facets of attachment anxiety and of avoidance. We investigated (1) whether individuals with OCD differed from controls in the facets of attachment security (anxiety and avoidance), (2) which attachment facets predicted a diagnosis of OCD, controlling for socio-demographics and obsessive beliefs, (3) which attachment facets predicted specific OCD symptoms, controlling for socio-demographics and obsessive beliefs. Two hundred seventy participants (135 OCD patients and 135 matched controls) completed the Obsessive-Compulsive Inventory-Revised, Obsessive Beliefs Questionnaire-46 and ASQ. OCD patients reported respectively lower and higher levels on confidence and attachment anxiety than controls. Higher need of approval was the most important predictor of OCD diagnosis beyond the other attachment facets, and even of the obsessive beliefs. Using multivariate generalised linear models, the two facets of attachment anxiety, the need for approval (that predicted higher levels of obsessing and ordering symptoms), and preoccupation with relationships (that predicted higher hoarding symptoms) seemed to explain variance over and above OCD-related beliefs and socio-demographics. Discomfort with closeness contributed to the predictions of ordering symptoms. In conclusion, the interpersonal dynamics related to attachment in OCD patients should be carefully considered during assessment and treatment of OCD patients in clinical practice.Besides classical semen parameters, semen stress tests (SSTs) are helpful tools to assess the fertilizing capacity of sperm. However, valid studies on SSTs in relation to fertility are rare because several corrections of common fertility parameters for female and male effects are required. Therefore, over a one-year period, we analyzed semen parameters of 260 ejaculates obtained from 130 Pietrain boars aged between 8 and 9 months in one AI center as well as 1521 corresponding insemination records for these ejaculates. Two consecutive ejaculates (4th and 5th) were collected from each boar and extended in DiluPorc™ BTS. In addition to routine semen evaluation, sperm motility was assessed after heat-resistance test (300 min incubation at 38 °C after seven days storage at 16 °C, HRT) and cold-resistance test (10 min incubation at 38 °C after three days storage at 6 °C, CRT). Generalized linear models (GLMs) were applied to analyze effects for the following predictors of farrowing rate (FR), number of total born (on in NTB and 7% of the total variation in NLB. Only 14.2% (n = 37) of the samples were both cold- and heat-resistant (≥65% of motile sperm). Cold- and heat-resistance were dependent factors (Chi-square, P = 0.001) and sperm motility after CRT and HRT showed a moderate positive correlation (rs = 0.40, P less then 0.001, Spearman's rho). Finally, ROC curves demonstrated that neither SST can be used as a sole test for predicting the fertilizing capacity of boar ejaculates.A large amount of literature has demonstrated that Perceived Criticism (PC)-that is, how critical a person believes a given relative is of him or her-is associated with negative clinical outcomes in a broad range of psychiatric disorders (e.g., relapse or recurrence of symptoms). link3 A possible mechanism behind the predictive value of PC might be its association with the stress regulation process. This is the first study to investigate differences in the psychophysiological response to a social stress task in young women (mean age = 21.66, SD = 4.33) with high (n = 40) and low (n = 39) PC. The physiological response was investigated by measuring two markers of sympathetic activity mediated by acetylcholine (skin conductance levels; SCL) and adrenaline (pre-ejection period; PEP) levels, respectively, and one marker of the vagally-mediated parasympathetic system (heart rate variability; HRV). Moreover, we investigated the anticipation and perception of social threat, in the form of criticism, during the stressor. No differences in HRV and SCL were observed. However, individuals high in PC mobilized fewer cardiovascular resources to deal with the stressor, reflected in an attenuated beta-adrenergic response (i.e., lower PEP response). Women high in PC also expected and perceived more criticism during the stress task. Together, our results indicate that women high in PC make heightened social threat anticipation and interpretations, and they tend to engage in less active coping when exposed to socially evaluated stressful events. Our findings indicate that PC is associated with underlying stress-related psychobiological vulnerabilities that may contribute to its association with negative clinical outcomes.Nitrogen (N) from anthropogenic sources has been identified as a major pollutant of the Great Barrier Reef (GBR), Australia. We developed a conceptual framework to synthesise and visualise the fate and transport of N from the catchments to the sea from a literature review. The framework was created to fit managers and policymakers' requirements to reduce N in the GBR catchments. We used this framework to determine the N stocks and transformations (input, sources, and outputs) for ecosystems commonly found in the GBR rainforests, palustrine wetlands, lakes, rivers (in-stream), mangroves and seagrasses. We included transformations of N such as nitrogen fixation, nitrification, denitrification, mineralisation, anammox, sedimentation, plant uptake, and food web transfers. This model can be applied to other ecosystems to understand the transport and fate of N within and between catchments. Importantly, this approach can guide management actions that attenuate N at different scales and locations within the GBR ecosystems.
