Patients with posttraumatic stress disorder (PTSD) exhibit smaller regional brain volumes in commonly reported regions including the amygdala and hippocampus, regions associated with fear and memory processing. In the current study, we have conducted a voxel-based morphometry (VBM) meta-analysis using whole-brain statistical maps with neuroimaging data from the ENIGMA-PGC PTSD working group.

T1-weighted structural neuroimaging scans from 36 cohorts (PTSD n = 1309; controls n = 2198) were processed using a standardized VBM pipeline (ENIGMA-VBM tool). We meta-analyzed the resulting statistical maps for voxel-wise differences in gray matter (GM) and white matter (WM) volumes between PTSD patients and controls, performed subgroup analyses considering the trauma exposure of the controls, and examined associations between regional brain volumes and clinical variables including PTSD (CAPS-4/5, PCL-5) and depression severity (BDI-II, PHQ-9).

PTSD patients exhibited smaller GM volumes across the frontal and temporal lobes, and cerebellum, with the most significant effect in the left cerebellum (Hedges’ g = 0.22, pcorrected = .001), and smaller cerebellar WM volume (peak Hedges’ g = 0.14, pcorrected = .008). We observed similar regional differences when comparing patients to trauma-exposed controls, suggesting these structural abnormalities may be specific to PTSD. Regression analyses revealed PTSD severity was negatively associated with GM volumes within the cerebellum (pcorrected = .003), while depression severity was negatively associated with GM volumes within the cerebellum and superior frontal gyrus in patients (pcorrected = .001).

PTSD patients exhibited widespread, regional differences in brain volumes where greater regional deficits appeared to reflect more severe symptoms. Our findings add to the growing literature implicating the cerebellum in PTSD psychopathology.

Despite advances in antiretroviral treatment (ART), human immunodeficiency virus (HIV) can detrimentally affect everyday functioning. Neurocognitive impairment (NCI) and current depression are common in people with HIV (PWH) and can contribute to poor functional outcomes, but potential synergies between the two conditions are less understood. Thus, the present study aimed to compare the independent and combined effects of NCI and depression on everyday functioning in PWH. We predicted worse functional outcomes with comorbid NCI and depression than either condition alone.

PWH enrolled at the UCSD HIV Neurobehavioral Research Program were assessed for neuropsychological performance, depression severity (≤minimal, mild, moderate, or severe; Beck Depression Inventory-II), and self-reported everyday functioning.

Participants were 1,973 PWH (79% male; 66% racial/ethnic minority; Age: M = 48.6; Education: M = 13.0, 66% AIDS; 82% on ART; 42% with NCI; 35% BDI>13). ANCOVA models found effects of NCI and depression symptom severity on all functional outcomes (ps < .0001). With NCI and depression severity included in the same model, both remained significant (ps < .0001), although the effects of each were attenuated, and yielded better model fit parameters (i.e., lower AIC values) than models with only NCI or only depression.

Consistent with prior literature, NCI and depression had independent effects on everyday functioning in PWH. There was also evidence for combined effects of NCI and depression, such that their comorbidity had a greater impact on functioning than either alone. Our results have implications for informing future interventions to target common, comorbid NCI and depressed mood in PWH and thus reduce HIV-related health disparities.

Developing integrated mental health services focused on the needs of children and young people is a key policy goal in England. The THRIVE Framework and its implementation programme, i-THRIVE, are widely used in England. This study examines experiences of staff using i-THRIVE, estimates its effectiveness, and assesses how local system working relationships influence programme success.

This evaluation uses a quasi-experimental design (10 implementation and 10 comparison sites.) Measurements included staff surveys and assessment of ‘THRIVE-like’ features of each site. Additional site-level characteristics were collected from health system reports. The effect of i-THRIVE was evaluated using a four-group propensity-score-weighted difference-in-differences model; the moderating effect of system working relationships was evaluated with a difference-in-difference-in-differences model.

Implementation site staff were more likely to report using THRIVE and more knowledgeable of THRIVE principles than comparison site staff. The mean improvement of fidelity scores among i-THRIVE sites was 16.7, and 8.8 among comparison sites; the weighted model did not find a statistically significant difference. However, results show that strong working relationships in the local system significantly enhance the effectiveness of i-THRIVE. Sites with highly effective working relationships showed a notable improvement in ‘THRIVE-like’ features, with an average increase of 16.41 points (95% confidence interval: 1.69–31.13, P-value: 0.031) over comparison sites. Sites with ineffective working relationships did not benefit from i-THRIVE (−2.76, 95% confidence interval: − 18.25–12.73, P-value: 0.708).

The findings underscore the importance of working relationship effectiveness in the successful adoption and implementation of multi-agency health policies like i-THRIVE.

Accurate diagnosis of bipolar disorder (BPD) is difficult in clinical practice, with an average delay between symptom onset and diagnosis of about 7 years. A depressive episode often precedes the first manic episode, making it difficult to distinguish BPD from unipolar major depressive disorder (MDD).

We use genome-wide association analyses (GWAS) to identify differential genetic factors and to develop predictors based on polygenic risk scores (PRS) that may aid early differential diagnosis.

Based on individual genotypes from case–control cohorts of BPD and MDD shared through the Psychiatric Genomics Consortium, we compile case–case–control cohorts, applying a careful quality control procedure. In a resulting cohort of 51 149 individuals (15 532 BPD patients, 12 920 MDD patients and 22 697 controls), we perform a variety of GWAS and PRS analyses.

Although our GWAS is not well powered to identify genome-wide significant loci, we find significant chip heritability and demonstrate the ability of the resulting PRS to distinguish BPD from MDD, including BPD cases with depressive onset (BPD-D). We replicate our PRS findings in an independent Danish cohort (iPSYCH 2015, N = 25 966). We observe strong genetic correlation between our case–case GWAS and that of case–control BPD.

We find that MDD and BPD, including BPD-D are genetically distinct. Our findings support that controls, MDD and BPD patients primarily lie on a continuum of genetic risk. Future studies with larger and richer samples will likely yield a better understanding of these findings and enable the development of better genetic predictors distinguishing BPD and, importantly, BPD-D from MDD.

To understand healthcare workers’ (HCWs) beliefs and practices toward blood culture (BCx) use.

Cross-sectional electronic survey and semi-structured interviews.

Academic hospitals in the United States.

HCWs involved in BCx ordering and collection in adult intensive care units (ICU) and wards.

We administered an anonymous electronic survey to HCWs and conducted semi-structured interviews with unit staff and quality improvement (QI) leaders in these institutions to understand their perspectives regarding BCx stewardship between February and November 2023.

Of 314 HCWs who responded to the survey, most (67.4%) were physicians and were involved in BCx ordering (82.3%). Most survey respondents reported that clinicians had a low threshold to culture patients for fever (84.4%) and agreed they could safely reduce the number of BCx obtained in their units (65%). However, only half of them believed BCx was overused. Although most made BCx decisions as a team (74.1%), a minority reported these team discussions occurred daily (42.4%). A third of respondents reported not usually collecting the correct volume per BCx bottle, half were unaware of the improved sensitivity of 2 BCx sets, and most were unsure of the nationally recommended BCx contamination threshold (87.5%). Knowledge regarding the utility of BCx for common infections was limited.

HCWs’ understanding of best collection practices and yield of BCx was limited.

There is emerging evidence that people with schizophrenia (SCH) struggle to form romantic relationships and are often dissatisfied with their sex lives. Intimate relationships are perceived as normalizing and related to a person’s recovery and better medication adherence. Nevertheless, this area remains scientifically unaddressed, and patients with SCH generally do not feel adequately supported in terms of their sexual health.

The study aims to assess whether challenges in establishing sexual relationships could be connected to: a) decreased salience of sexual intimacy and/or b) compromised ability to detect, recognize, and react to signals of sexual interest.

Forty-three patients with SCH (29 males and 14 females) and a control group of twenty-four participants (11 males and 13 females) were exposed to our first experiment, the Circular attention task. This task was designed to evaluate the salience of erotic stimuli compared to neutral ones. At the beginning of each trial, a black fixation circle appeared in the middle of the screen. When a fixation of 250 ms or longer was detected within the circular area of interest (AOI) around the fixation circle, the fixation circle disappeared, and a pair of erotic/neutral pictures appeared. During the experiment, the eye movements were measured using the eye-tracking device Eyelink 1000plus. For data analysis, we used Wilcoxon signed-rank test to assess the differences between the mean latency to first fixation, mean duration of first fixation, and mean proportion of time spent gazing at the stimulus both for sexual and neutral pictures in the whole sample regardless of sex and patient status. More detailed analysis was performed using 2 (sex: male, female) x 2 (status: patient, control) two-way ANOVA.

Considering the whole sample there was a significant difference in mean latency to first fixation (W = 707, p = 0.007, rrb = -0.379) and mean duration of first fixation (W = 1923, p < 0.001, rrb = 0.739). There was a shorter latency to first fixations towards sexual pictures (M = 952.33 ms) than to neutral pictures (M = 1005.30 ms). First fixations were longer for sexual pictures (M = 280.96 ms) than for neutral pictures (M = 243.73 ms). There was an effect overall in the sample towards the sexual pictures, but it was not different for participants based on their sex or patient status.

Findings revealed that interest in explicit sexual stimuli does not differ based on sex or patient status. Patients with SCH appear to find explicit erotic signals sexually salient, suggesting their interest in sexual intimacy. Our study will further investigate whether persons with SCH are able to interpret, recognize and respond to signals of sexual interest. Based on our results, the guidelines for sexological remediation will be developed.

The COVID-19 pandemic has led to a rise in psychological disorders among adolescents and young adults. There is an increase in the prevalence of likely anxiety and likely depression among the subscribers of MoreGoodDays supportive text message program, reflecting the impact of the COVID-19 pandemic on this cohort.

To assess the prevalence, severity, and correlates of likely generalized anxiety disorder (GAD) and likely major depressive disorder (MDD) among subscribers of MoreGoodDays program.

This study used a cross-sectional design. An online survey questionnaire was used to collect sociodemographic and clinical information from subscribers of MoreGoodDays program, a daily supportive text message program co-designed with adolescents and young adults for their peers in Alberta. Validated instruments, the Generalized Anxiety Disorder GAD-7 and Patient Health Questionnaire-9 PHQ-9 were used to collect information on likely GAD and likely major depressive disorder (MDD), respectively. Data was analyzed with SPSS version 25 using chi-squared tests and binary logistic regression analysis.

343 subscribers of MoreGoodDays participated in the survey. Overall, 117 (56.0%) respondents had a likely MDD and 97 (46.6%) had a likely GAD. Participants who would like to receive mental health counselling were 27 times more likely to experience GAD (OR = 27; 95% CI: 3.09–250.00) and 40 times more likely to experience MDD (OR = 40.03; 95% CI: 4.43–361.51) than those who did not. Respondents who had received mental health counselling in the past were 18.5 times more likely to experience MDD compared with those who had not (OR = 18.52; 95% CI: 1.55–200.00). Demographic variables, including age, education, employment, and relationship status, and clinical variables, such as history of anxiety, depression, obsessive-compulsive disorder, ADHD, and adverse childhood experience, did not independently the predict presence of likely GAD or MDD in subscribers of MoreGoodDays.

The prevalence of anxiety and depression was relatively high among subscribers of MoreGoodDays, indicating the long-term effect of the COVID-19 pandemic. This finding has significant implications in the broader context of mental health research and emphasizes the need for more research into innovative mental health support for this cohort. The desire to receive counselling was predictive of both anxiety and depression and is a positive sign of the openness of this cohort to receive psychological intervention. Since this group is mostly adapted to mobile text technology, government agencies and policymakers should prioritize and implement readily accessible interventions such as supportive text messages to support their psychological well-being.

Auditory verbal hallucinations (AVHs) in schizophrenia have been suggested to arise from failure of corollary discharge mechanisms to correctly predict and suppress self-initiated inner speech. However, it is unclear whether such dysfunction is related to motor preparation of inner speech during which sensorimotor predictions are formed. The contingent negative variation (CNV) is a slow-going negative event-related potential that occurs prior to executing an action. A recent meta-analysis has revealed a large effect for CNV blunting in schizophrenia. Given that inner speech, similar to overt speech, has been shown to be preceded by a CNV, the present study tested the notion that AVHs are associated with inner speech-specific motor preparation deficits.

The present study aimed to provide a useful framework for directly testing the long-held idea that AVHs may be related to inner speech-specific CNV blunting in patients with schizophrenia. This may hold promise for a reliable biomarker of AVHs.

Hallucinating (n=52) and non-hallucinating (n=45) patients with schizophrenia, along with matched healthy controls (n=42), participated in a novel electroencephalographic (EEG) paradigm. In the Active condition, they were asked to imagine a single phoneme at a cue moment while, precisely at the same time, being presented with an auditory probe. In the Passive condition, they were asked to passively listen to the auditory probes. The amplitude of the CNV preceding the production of inner speech was examined.

Healthy controls showed a larger CNV amplitude (p = .002, d = .50) in the Active compared to the Passive condition, replicating previous results of a CNV preceding inner speech. However, both patient groups did not show a difference between the two conditions (p > .05). Importantly, a repeated measure ANOVA revealed a significant interaction effect (p = .007, ηp2 = .05). Follow-up contrasts showed that healthy controls exhibited a larger CNV amplitude in the Active condition than both the hallucinating (p = .013, d = .52) and non-hallucinating patients (p < .001, d = .88). No difference was found between the two patient groups (p = .320, d = .20).

The results indicated that motor preparation of inner speech in schizophrenia was disrupted. While the production of inner speech resulted in a larger CNV than passive listening in healthy controls, which was indicative of the involvement of motor planning, patients exhibited markedly blunted motor preparatory activity to inner speech. This may reflect dysfunction in the formation of corollary discharges. Interestingly, the deficits did not differ between hallucinating and non-hallucinating patients. Future work is needed to elucidate the specificity of inner speech-specific motor preparation deficits with AVHs. Overall, this study provides evidence in support of atypical inner speech monitoring in schizophrenia.

Health Psychology is aggregated to clinical studies providing physicians, nurses, and psychotherapists with psychodynamics of sick persons, facilitating interpersonal relationships and greater adherence to treatments. How do people deal with illness and treatment from what they symbolize in experiences of becoming ill? Watch & Wait Protocol for patients with rectal cancer is an active surveillance as an alternative approach in surgical medical management. Patients are followed with physical examinations, endoscopy, and imaging. Observation carried out through periodic examinations aims to avoid surgery stage while rectal cancer is maintained.

To interpret emotional meanings attributed by patients, after adhering to the W&W protocol for rectal cancer, to life experiences of watching and waiting for the disease course.

Clinical-Qualitative Method (Turato. Portuguese Psychos. J, 2000 2(1): 93-108). For data collection, the first author used Semi-Directed Interview with Open-ended Questions In-Depth and Field Notes, after acculturation. Sample closed by information saturation (Fontanella et al. Cad Saude Publica. 2008; 24(1): 17-27). Interviews conducted by the first author, a female psychologist. We employed the Seven Steps of the Clinical-Qualitative Content Analysis (Faria-Schützer et al. Cien Saude Colet. 2021; 26(1): 265-274) to construct categories. Theoretical framework was the Balintian Medical Psychology. Findings were validated by peer reviewers from Lab of Clinical-Qualitative Research.

Sample had 10 patients, 3 female and 7 male, from 52 to 77 years. Interviews carried out from October 2022 to March 2023. We constructed 03 categories: 1) Fate out of hands - “I get sick just coming in here.” There is an apprehension experienced in each medical evaluation to check the clinical condition because the symbol of waiting is not having the own destiny in the hands. 2) Psychic defence - “Sometimes I even thought if I had to live on a grant for the rest of my life or die!” Imagining the worst is a psychic defence because if this probability occurs, the mind has already begun its elaboration. 3) Life upside down - “I was going to have the surgery, use a bag, my life was going to be upside down.” Anxiety generated by waiting is a mental disorganizing.

Attitudes of observing and waiting carry different symbolisms to those who work with scientific thinking and who experience the observation of their own disease and the wait for what conduct they will receive. Observing oneself in illness requires acceleration of changes in ego identity. Waiting in front of illness asks the ego to think the worst. It is not a volitional choice. Preparing for the worst is a defensive necessity in the emotional sphere to avoid surprises that take to mental rupture.
