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.

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.

Postpartum depression (PPD), now referred to as perinatal depression, is a prevalent and debilitating mood disorder that reduces health-related quality of life (HRQoL) and psychosocial functioning. Esketamine, which is efficacious in adults with treatment-resistant depression and individuals with depression and suicidality, is also analgesic in pain management during childbirth labour. Herein, we investigate the efficacy of prophylactic esketamine in reducing the incidence of PPD.

We performed a systematic review (i.e., PubMed, Scopus, and Ovid databases; inception to January 22, 2024) of randomized controlled trials that investigated the use of esketamine for PPD. We delimited our search to studies that prespecified the prevention of PPD with esketamine as the primary outcome. A meta-analysis was performed on PPD incidence rates using a random effects model.

Our analysis consisted of seven studies that met our eligibility criteria. We found that esketamine was significantly associated with a decreased incidence of PPD diagnosis within one week of childbirth (OR = 0.30, 95% CI = [0.15, 0.60], p = 0.0047). We also observed that esketamine was significantly associated with a decreased incidence of PPD diagnosis between 4 to 6 weeks post-delivery (OR = 0.33, 95% CI = [0.18, 0.59], p = 0.0034).

Our results indicate that esketamine may have preventive antidepressant effects during the postpartum period. The aforementioned points have both mechanistic and clinically meaningful implications for the treatment of PPD.

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.

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.

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.

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.

Sleep pattern alteration is a core feature of bipolar disorder (BD), often challenging to treat and affecting clinical outcomes. Suvorexant, a hypnotic agent that decreases wakefulness, has shown promising results in treating primary insomnia. To date, data on its use in BD are lacking. This study evaluated the efficacy and tolerability of adjunctive suvorexant for treatment-resistant insomnia in BD patients.

Thirty-six BD outpatients (19 BDI, 69.4% female, 48.9 [±15.2] years) were randomized for 1 week to double-blind suvorexant (10–20 mg/day) versus placebo. Then, all subjects who completed the randomized phase were offered open suvorexant for 3 months. Subjective total sleep time (sTST) and objective total sleep time (oTST) were assessed.

During the randomized control trial (RCT) phase, an overall increase in the oTST emerged, which was statistically significant for the Cole–Kripke algorithm (p = 0.035). The comparison between the suvorexant and placebo groups was limited by significant differences between measurements at baseline. During the open phase, no significant improvement was detected relative to either sTST and oTST. No adverse events nor major intolerances were reported.

Efficacy results are inconsistent. During the RCT phase, only a small increase in the objective oTST emerged, while during the open phase, no significant improvement was detected. While this is the first ever study of suvorexant in BD-related insomnia, the limitation of the small sample and the high rate of dropouts limits the generalizability of these findings. Larger studies are needed to assess suvorexant in treating BD-related insomnia.

Scientific literature has highlighted the link between autism spectrum disorder (ASD) and anxiety disorders, but few studies have delved into the relationship between ASD and panic-agoraphobic disorders. The aim of this study is to investigate the relationship between autism spectrum and panic-agoraphobic symptoms, examining whether and which autistic domains are predictive of the presence of specific panic-agoraphobic symptoms.

Forty-five adult subjects with ASD and 50 healthy controls (HCs) were evaluated through the Structured Clinical Interview for DSM-5, Research Version and assessed with the Adult Autism Subthreshold Spectrum (AdAS Spectrum) and the Panic-Agoraphobic – Short Version (PAS-SV) questionnaires. Statistical analyses included Mann–Whitney U test, chi-square test, and a set of linear and logistic regression analyses.

The PAS-SV total and domain scores were significantly higher in the ASD group than in the HC group. A higher AdAS total score appeared to be predictive of a higher PAS-SV total score. The AdAS domain Restricted Interests and Rumination would increase the risk of obtaining higher PAS-SV total and domain scores. Conversely, the AdAS Spectrum domain Inflexibility and Adherence to Routine would predict lower total PAS-SV score.

This study revealed a greater representation of panic-agoraphobic symptoms in adults with ASD, as well as an increased risk of showing such symptoms in the presence of significant autistic traits. Restricted interests and ruminative thinking emerged as predominant risk factors for panic-agoraphobic manifestations.
