A double-blind, randomized, active-controlled, parallel-group, noninferiority trial (NCT03345342) demonstrated that paliperidone palmitate once-every-6-months (PP6M) was noninferior to paliperidone palmitate once-every-3-months (PP3M) in preventing relapse in clinically stable adults with schizophrenia. This post hoc analysis assessed efficacy and safety following transition to PP6M from paliperidone once-monthly (PP1M) versus PP3M.

Adults with schizophrenia who were clinically stable on moderate/high doses of PP1M or PP3M were randomly assigned 1:2 to dorsogluteal PP3M or PP6M treatment for 12 months. The primary efficacy measure was time to relapse during the 12-month DB phase. Secondary endpoints included change from DB baseline to endpoint in Positive and Negative Syndrome Scale (PANSS) total and subscale scores, Clinical Global Impression-Severity (CGI-S) scale score, and Personal and Social Performance (PSP) scale score. Safety was assessed by treatment-emergent adverse events (TEAEs), vital signs, and clinical laboratory tests.

Of 702 patients in the study, 231 transitioned from PP1M to PP6M and 247 transitioned from PP3M to PP6M. Low relapse rates for PP6M were observed regardless of transition pathway (PP1M/PP6M: 7.8%; PP3M/PP6M: 7.3%). Changes from DB baseline to endpoint in PANSS total, PSP, and CGI-S scores were similar between transition groups. In the DB phase, ≥1 TEAE was observed in 61.0% and 63.2% of patients in the PP1M/PP6M and PP3M/PP6M, groups, respectively.

Adults with schizophrenia who transitioned to PP6M from either PP1M or PP3M experienced similarly low relapse rates. Additionally, symptom and functionality scores supported the primary analysis and, along with TEAE incidences, were comparable between transition groups.

Hoarding disorder studies are primarily based on persons who seek treatment and demonstrate good insight. The aim of the present study is to evaluate whether there are differences between community and treatment-seeking samples of individuals with hoarding disorder (HD).

Fourteen people with HD from the community and twenty treatment-seeking people with HD were assessed by a battery of instruments to evaluate HD features and other associated characteristics.

Compared to the treatment-seeking sample, the HD community sample was older, had poorer insight, and had a lower prevalence of comorbid obsessive-compulsive disorder (OCD). There were no differences in gender, education, presence of psychiatric comorbidities, quality of life, and hoarding behavior characteristics between the samples. The final logistic regression model with the Dimensional Obsessive-Compulsive Scale (DOCS) as the single predictor of treatment-seeking status was statistically significant, indicating that it was able to distinguish between the two samples. The model explained between 20.7% and 27.9% of the variance of subjects, and correctly classified 67.6% of cases.

Our results indicate that there appear to be few differences between the treatment-seeking and community samples of individuals with HD. The presence of comorbid OCD in treatment-seeking groups seems to be more frequent than in HD community samples.

Cognitive and psychiatric symptoms have been increasingly reported after severe acute respiratory syndrome coronavirus 2 infection, developing soon after infection and possibly persisting for several months. We aimed to study this syndrome and start implementing strategies for its assessment.

Consecutive patients, referred by the infectious disease specialist because of cognitive complaints after COVID-19, were neurologically evaluated. Neurological evaluation included a cognitive screening test (Montreal Cognitive Assessment, MoCA). Moreover, patients were invited to fill out a general symptom questionnaire and a self-administered multidimensional assessment of psychiatric symptoms, followed by a full psychiatric assessment if scores were above validated cutoffs.

Of 144 referred patients, 101 (mean age 55.2±13.1, 63.4% females) completed the cognitive screening and the self-administered psychiatric questionnaire. Acute infection severity was low for most patients and the most common persisting symptoms were fatigue (92%), sleep problems (69.5%), and headache (52.4%). MoCA outlined cognitive deficits in ≥1 cognitive domain in 34% of patients, mainly in memory and attention. About 60% of patients presented depressive, anxiety, or stress-related symptoms. Psychiatric scale scores significantly correlated with overall symptom burden and MoCA score. No significant correlation was found between MoCA scores and overall symptom burden.

We hypothesize that persistent cognitive complaints after COVID-19 might reflect a concomitant or reactive psychopathological condition, possibly coupled with an infection-related impact on cognitive functions. The application of a combined neurological and psychiatric assessment seems crucial to appraise the nature of post-COVID-19 condition.

People with mental illness are overrepresented throughout the criminal justice system. In Italy, the Judicial Psychiatric Hospitals are now on the edge of their closure in favor of small-scale therapeutic facilities (REMS). Therefore, when patients end their duty for criminal behaviors, their clinical management moves back to the outpatient psychiatric centers. Elevated risks of rule-violating behavior are not equally shared across the spectrum of psychiatric disorders. To broaden the research in this area, we analyzed sociodemographic, clinical, and forensic variables of a group of psychiatric patients with a history of criminal behaviors, attending an outpatient psychiatric service in Milan, focusing on substance use disorder (SUD).

This is a cross-sectional single center study, conducted from 2020. Seventy-six subjects with a history of criminal behaviors aged 18 years or older and attending an outpatient psychiatric service were included. Demographic and clinical variables collected during clinical interviews with patients were retrospectively retrieved from patients’ medical records. Appropriate statistical analyses for categorical and continuous variables were conducted.

Data were available for 76 patients, 51.3% of them had lifetime SUD. Lifetime SUD was significantly more common in patients with long-acting injectable antipsychotics therapy, a history of more than 3 psychiatric hospitalizations, and a history of previous crimes, particularly economic crimes. Additionally, this last potential correlation was confirmed by logistic regression.

Data emerging from this survey provide new information about offenders with lifetime SUD attending an Italian mental health service. Our preliminary results should be confirmed in larger sample sizes.

This study examined children at the onset of tic disorder (tics for less than 9 months: NT group), a population on which little research exists. Here, we investigate relationships between the baseline shape and volume of subcortical nuclei, diagnosis, and tic symptom outcomes.

187 children were assessed at baseline and a 12-month follow-up: 88 with NT, 60 tic-free healthy controls (HC), and 39 with chronic tic disorder/Tourette syndrome (TS), using T1-weighted MRI and total tic scores (TTS) from the Yale Global Tic Severity Scale to evaluate symptom change. Subcortical surface maps were generated using FreeSurfer-initialized large deformation diffeomorphic metric mapping. Linear regression models correlated baseline structural shapes with follow-up TTS while accounting for covariates, with relationships mapped onto structure surfaces.

We found that the NT group had a larger right hippocampus compared to HC. Surface maps illustrate distinct patterns of inward deformation in the putamen and outward deformation in the thalamus for NT compared to controls. We also found patterns of outward deformation in almost all studied structures when comparing the TS group to controls. The NT group also showed consistent outward deformation compared to TS in the caudate, accumbens, putamen, and thalamus. Subsequent analyses including clinical symptoms revealed that a larger pallidum and thalamus at baseline correlated with less improvement of tic symptoms at follow-up.

These observations constitute some of the first prognostic biomarkers for tic disorders and suggest that these subregional shape and volume differences may be associated with the outcome of tic disorders.

War participation risks mental disorders. Ukrainian combatants in Anti-Terrorist Operation/Joint Forces Operation since 2014 receive psychiatric care. Some show unique symptoms, not fitting recognized disorders, termed post-combat delayed response (tension) syndrome. The aim of this study was to establish diagnostic criteria and develop a scale of differential diagnosis of post-combat delayed response (tension) syndrome.

This was a clinical retrospective study conducted on the basis of Zaporizhzhia Military Hospital and Zaporizhzhia and State Medical University, Ukraine, in the period from 2015 to 2021. Combatants of Ukraine—members of Anti-Terrorist Operation/Joint Forces Operation were involved in the study. In total, 426 male combatants were surveyed from whom those suffering from post-traumatic stress disorder (n = 24), neurasthenia (n = 35), and post-combat delayed response (tension) syndrome (n = 46) were selected.

The key symptoms of post-combat delayed response (tension) syndrome were selected and ranked in order of their differential diagnostic value. The diagnostic scale for post-combat delayed response (tension) syndrome was developed, which consists of 12 points.

The received anamnestic information is important for classifying patients at risk of post-combat delayed response (tension) syndrome.

The World Health Organization (WHO) has defined Post-COVID-19 Condition (PCC) as the onset of symptoms within three months after resolution of an acute SARS-CoV-2 infection, wherein symptoms persist for at least two months and cannot be explained by another medical/psychiatric condition. Persons living with PCC report debilitating symptoms including, but not limited to, depressive symptoms and motivational deficits. The aim of this post-hoc analysis was to evaluate the association between depressive symptoms and motivation in adults with PCC.

We conducted a post-hoc analysis of an 8-week, double-blind, randomized, placebo-controlled trial evaluating adults (18 years or older) in Canada with WHO-defined PCC and cognitive symptoms. This post-hoc analysis is comprised of baseline data that evaluates the association between depressive symptom severity measured by the 16-item Quick Inventory of Depressive Symptomatology-Self Report (QIDS-SR-16) and motivational systems measured by the Behavioral Inhibition System/Behavioral Activation System Questionnaire (BIS/BAS).

There was a statistically significant association between depressive symptoms and BIS (β = -0.041 95% CI [-0.066, -0.016], p<0.05), BAS reward responsiveness (β = 0.043 95% CI [0.012, 0.074], p<0.05), sex (β = -0.137 95% CI [-0.266, -0.008], p<0.05), and confirmed COVID-19 infection (β = 0.196 95% CI [0.061, 0.332], p<0.05).

Depressive symptoms were associated with motivational deficits in persons living with PCC. Optimizing treatment for depressive symptoms may potentially improve aspects of motivational impairment amongst persons with PCC. All patients presenting with MDD and a history of COVID-19 infection should be assessed for the presence of PCC.

Dextromethorphan/bupropion (DXM/BUP) received Food and Drug Administration (FDA) approval for the treatment of adults with major depressive disorder (MDD) in August 2022. This combination is not known to have abuse liability and is not currently scheduled by the Drug Enforcement Administration (DEA). Notwithstanding, dextromethorphan is a drug of abuse. Herein, we sought to determine whether DXM/BUP has alcohol and/or substance misuse liability.

We evaluated spontaneous reports of terms such as “alcohol problem, alcoholism, alcohol abuse, substance dependence, substance use disorder (SUD), substance abuse, drug dependence, drug use disorder and drug abuse” in the FDA Adverse Event Reporting System (FAERS). The FAERS is a spontaneous reporting database of adverse events submitted to the FDA.

We performed a comparative assessment of the alcohol and/or substance misuse liability of DXM/BUP since its market authorization in August 2022, using acetaminophen as the control. Dextromethorphan served as the upper-bound reference point. Our findings showed that, since August 2022, dextromethorphan had a significant reporting odds ratio (ROR) for “drug abuse.” In contrast, DXM/BUP did not have a significant ROR for any of the categories of alcohol and/or substance misuse evaluated. Limitations of our findings derive largely from the limitations of the FAERS and its data capture method.

The absence of alcohol or substance misuse reported to the FAERS with DXM/BUP accords with the lack of evidence of abuse liability prior to FDA approval and its non-scheduling by the DEA.

The hikikomori phenomenon has recently gained growing global interest, and evidences of its association with other psychopathological dimensions are slowly but steadily emerging. We aimed to evaluate the presence and correlates of hikikomori tendencies in an Italian University population, focusing on its relationships with autism spectrum, pathological computer gaming, and eating disorders. In particular, to our knowledge, no study has yet systematically evaluated the latter association, using psychometric instruments tailored to assess eating disorder symptoms.

2574 students were recruited via an online survey. All participants were assessed with the Hikikomori Questionnaire-25 (HQ-25), the Adult Autism Subthreshold Spectrum Questionnaire (AdAS Spectrum), the Eating Attitude test-26 (EAT-26), and the Assessment of Internet and Computer Game Addiction (AICA-S).

The results outlined how hikikomori risk was significantly correlated to autistic dimensions, altered eating behaviors, and videogame addiction. The closest relationship was detected with the autism spectrum. Interestingly, pathological computer gaming, most autistic dimensions, and EAT-26 oral control emerged as significant predictors of a greater risk for hikikomori, while the proneness to inflexibility and adherence to routine emerged as negative predictors.

Our findings support the association among hikikomori, autism spectrum, pathological computer game use, and eating disorder symptoms.

Deep brain stimulation (DBS) of the subthalamic nucleus (STN) improves motor outcomes in Parkinson’s disease (PD) but may have adverse long-term effects on specific cognitive domains. The aim of this study was to investigate the association between total electrical energy (TEED) delivered by DBS and postoperative changes in verbal fluency.

Seventeen PD patients undergoing bilateral STN-DBS were assessed with the Alternate Verbal Fluency Battery (AVFB), which includes phonemic (PVF), semantic (SVF), and alternate verbal fluency (AVF) tests, before surgery (T0) and after 6 (T1) and 12 months (T2). Bilateral TEED and average TEEDM were recorded at T1 and T2. For each AVFB measurement, changes from T0 to T1 (Δ-01) and from T0 to T2 (Δ-02) were calculated.

At T1, PVF (p = 0.007) and SVF scores (p = 0.003) decreased significantly. TEED measures at T1 and T2 were unrelated to Δ-01 and Δ-02 scores, respectively. However, an inverse, marginally significant association was detected between the TEEDM and Δ-01 scores for the AVF (p = 0.041, against an αadjusted = 0.025).

In conclusion, the present reports provide preliminary evidence that TEED may not be responsible or only slightly responsible for the decline in VF performance after STN-DBS in PD.

Antidepressants are commonly prescribed for mood disorders. Epidemiological studies suggest antidepressant use may be associated with cataracts and glaucoma. We aim to investigate the association between antidepressants and cataracts and glaucoma.

Data was collected from the United States Food and Drug Administration Adverse Event Reporting System. Reporting odds ratio (ROR) and Bayesian information components (IC025) were calculated for antidepressants (ie, selective serotonin reuptake inhibitors [SSRIs], selective norepinephrine reuptake inhibitors [SNRIs], serotonin-norepinephrine-dopamine reuptake inhibitors, serotonin modulators and stimulators, serotonin antagonists and reuptake inhibitors [SARIs], norepinephrine reuptake inhibitors, norepinephrine-dopamine reuptake inhibitors, tricyclic antidepressants [TCAs], tetracyclic antidepressants [TeCAs], and monoamine oxidase inhibitors [MAOIs]). The reference agent was acetaminophen.

TeCAs and MAOIs were significantly associated with a decreased risk of cataracts (ROR = 0.11-0.65 and 0.16-0.69, respectively). TCAs, brexanolone, esketamine, and opipramol reported an increased cataract risk (ROR = 1.31-12.81). For glaucoma, SSRIs, SNRIs, SARIs, TCAs, MAOIs, and other investigated antidepressants reported significant RORs ranging from 1.034 to 21.17. There was a nonsignificant association of angle closure glaucoma (ACG) and open angle glaucoma (OAG) with the investigated antidepressants.

For adverse event cases, multiple suspected product names are listed, and as cases are not routinely verified, there may be a possibility of duplicate reports and causality cannot be established.

Most of the investigated antidepressants were associated with a lower risk of cataract reporting. TCAs, brexanolone, esketamine, and opipramol were associated with greater odds of cataract. For most antidepressants, there was an insignificant increase in reports of ACG and OAG.

Improving functioning in adults with major depressive disorder (MDD) and bipolar disorder (BD) is a priority therapeutic objective.

This retrospective post hoc secondary analysis evaluated 108 patients with MDD or BD receiving the antidepressants vortioxetine, ketamine, or infliximab. The analysis aimed to determine if changes in objective or subjective cognitive function mediated the relationship between depression symptom severity and workplace outcomes. Cognitive function was measured by the Perceived Deficits Questionnaire (PDQ-5), the Digit Symbol Substitution Test (DSST), and the Trail Making Test Part B (TMT-B). Depression symptom severity was measured by the Montgomery–Åsberg Depression Rating Scale (MADRS). Workplace function was measured by the Sheehan Disability Scale (SDS) work–school item.

When co-varying for BMI, age, and sex, the association between MADRS and SDS work scores was partially mediated by PDQ-5 total scores and DSST total scores, but not DSST error scores and TMT-B time.

This study was insufficiently powered to perform sub-group analyses to identify distinctions between MDD and BD populations as well as between antidepressant agents.

These findings suggest that cognitive impairment in adults with MDD and BD is a critical mediator of workplace function and reinforces its importance as a therapeutic target.

Cognitive and psychiatric symptoms are frequently reported after SARS-CoV-2 infection, but their interplay has been only partially explored. We investigated frequency and severity of psychiatric symptoms in patients with persistent cognitive complaints after COVID-19.

We conducted a cross-sectional study. Neurologists assessed 101 patients reporting cognitive symptoms after COVID-19. Patients were invited to fill a screening battery with self-reported psychometric scales (Depression Anxiety Stress Scales-21, Impact of Event Scale-Revised, Insomnia Severity Index). Patients scoring above validated cut-offs in ≥1 scale were referred to psychiatrists who administered the Mini-International Neuropsychiatric Interview (M.I.N.I.), Hamilton Anxiety (HAM-A), and Hamilton Depression (HAM-D) rating scales and asked to complete the Personality Inventory for DSM-5-Brief Form (PID-5-BF).

Out of the 57 referred patients, 38 (64.4%) accepted to undergo the psychiatric examination. Among these, 18 (47.4%) were diagnosed with adjustment disorder (23.7%), anxiety disorder (10.5%), major depressive disorder (7.9%), and post-traumatic stress disorder (2.6%). Pharmacologic treatment before post-COVID condition (present in 12 patients, 31.6%) was associated with a score above cut-off on the HAM-A and HAM-D scales. A longer duration of untreated psychiatric illness after COVID-19 was associated with worse scores on the same scales. Patients with a higher PID-5-BF total score had a higher probability of receiving a psychiatric diagnosis.

Almost half of patients with post-COVID-19 conditions reporting cognitive symptoms were found to suffer from a psychiatric condition after psychiatric evaluation. The application of a psychiatric screening in a population suffering from long-term effects of COVID-19 can lead to early diagnosis and timely treatment.

In VIVRE (NCT04448431), vortioxetine was associated with significantly higher rates of symptomatic and functional remission, better daily and social functioning, and greater treatment satisfaction than desvenlafaxine in patients with major depressive disorder (MDD) and partial response to selective serotonin reuptake inhibitor (SSRI) therapy. This analysis further explored the relative improvement in patient functioning with vortioxetine versus desvenlafaxine.

VIVRE was a randomized, double-blind study of vortioxetine (10 or 20 mg/day) versus desvenlafaxine (50 mg/day) in adults with MDD and partial response to initial SSRI monotherapy. Mean percentage changes from baseline to week 8 in Functioning Assessment Short Test (FAST) total and domain scores were analyzed by treatment group in the overall population and in working patients.

In the overall population, the mean reduction in FAST total score from baseline after 8 weeks of treatment was 37.2% in vortioxetine-treated patients versus 31.8% in desvenlafaxine-treated patients (P = 0.04). Significantly greater improvements versus desvenlafaxine were seen in vortioxetine-treated patients for FAST autonomy, cognitive functioning, and interpersonal-relationships scores (all P < 0.05). In working patients, the mean reduction in FAST total score from baseline at week 8 was 38.7% versus 32.1% in the vortioxetine and desvenlafaxine groups, respectively (P = 0.04). Significant correlations were seen between absolute changes in patient functioning, and those in depression severity and health-related quality of life.

Vortioxetine was significantly better than desvenlafaxine in improving overall functioning as well as daily, social, and cognitive functioning in patients with MDD with inadequate response to prior SSRI therapy.

To describe and compare the prevalence of psychosocial and psychiatric disorders among veterans with multiple sclerosis (MS) and a propensity-score-matched group of veterans without MS, and to identify sociodemographic and clinical characteristics associated with comorbid psychosocial and psychiatric problems among veterans with MS.

Data were linked and extracted from the Veterans Affairs (VA) Homeless Operations Management and Evaluation System and the Corporate Data Warehouse. The total sample comprised 27,342 veterans in the VA healthcare system between January 1, 2022, and June 30, 2023, who met eligibility criteria for an MS diagnosis (n=13,671) and 1:1 propensity-score-matched sample of veterans who did not have MS (n=13,671). MS diagnosis, substance use disorder (SUD), mental illness, and homelessness were defined using standard ICD-10 codes. Covariates included sex, age, Charlson Comorbidity Index (CCI), and VA service-connected disability rating.

A higher prevalence of mental illness among veterans with MS (33%) was found compared with those without MS (31%). Multivariable logistic regression models indicated MS was negatively associated with diagnoses of alcohol use disorder, stimulant use disorders, posttraumatic stress disorder, and schizophrenia/schizoaffective disorder but positively associated with diagnoses of cannabis use disorder and major depressive disorder. MS was not significantly related to homelessness. Disparities in psychosocial and psychiatric disorders among veterans with MS are described.

This study provides novel insights regarding rates of homelessness, SUD, and mental illnesses among veterans with MS. Interdisciplinary approaches to identification and management of mental illness, SUD, and homelessness among veterans with MS are critically needed.

This study aimed to investigate the effects of esketamine (Esk) combined with dexmedetomidine (Dex) on postoperative delirium (POD) and quality of recovery (QoR) in elderly patients undergoing thoracoscopic radical lung cancer surgery.

In this prospective, randomized, and controlled study, 172 elderly patients undergoing thoracoscopic radical lung cancer surgery were divided into two groups: the Esk + Dex group (n = 86) and the Dex group a (n = 86). The primary outcome was the incidence of POD within 7 days after surgery and the overall Quality of Recovery−15 (QoR − 15) scores within 3 days after surgery. Secondary outcomes included postoperative adverse reactions, extubation time, PACU stay, and hospitalization time. Serum levels of IL-6, IL-10, S100β protein, NSE, CD3+, CD4+, and CD8+ were detected from T0 to T5.

Compared with the Dex group, the incidence of POD in the Esk + Dex group was significantly lower at 7 days after surgery (14.6% vs 30.9%; P = 0.013). The QoR − 15 score was significantly increased 3 days after surgery (P < 0.01). Levels of IL-6 and CD8+ were significantly decreased, and IL − 10 levels were significantly increased at T1-T2 (P < 0.05). At T1-T4, NSE levels were significantly decreased, while CD3+ and CD4+/CD8+ values were significantly increased (P < 0.01). At T1-T5, serum S100β protein concentration decreased significantly, and CD4+ value increased significantly (P < 0.01). The incidence of nausea/vomiting and hyperalgesia decreased significantly 48 hours after surgery (P < 0.01). The duration of extubation, PACU stay, and postoperative hospitalization were significantly shortened.

Esketamine combined with dexmedetomidine can significantly reduce the POD incidence and improve the QoR in patients undergoing thoracoscopic radical lung cancer surgery, which may be related to the improvement of cellular immune function.
