3-chloromethcathinone (3-CMC) is a synthetic cathinone that gained relevance, having been involved in a large number of seizures and poisoning reports. Despite this, literature currently lacks information on its pharmaco-toxicological effects. This study aims to investigate the acute sensorimotor and physiological effects of 3-CMC (0.1–30 mg/kg; i.p.) in male and female CD-1 mice and its effects (1 and 10 mg/kg) on Prepulse Inhibition (PPI). Furthermore, we describe a series of 3-CMC (or CMC)-related human intoxications (Italy, 2014–2025) registered by the PCC–National Toxicology Information Centre. Finally, we predicted the ADMET properties of 3-CMC compared to 2-CMC, 4-CMC, 2-MMC, and two 3-CMC metabolites. 3-CMC induced in mice locomotor stimulation in mice, relevant tachypnoea and hypothermia, sensorimotor, and PPI alterations were observed only at high doses, with minor sex differences. All intoxications were non-fatal and involved male patients showing psychomotor agitation, psychosis, aggressiveness, CNS depression, but also cardiac arrhythmias, thoracic pain, and tachypnea. N-dealkylation, N-hydroxylation, and phenyl hydroxylation were the main predicted reactions. Drug–drug interaction potential and cardiotoxicity were suggested for all compounds. This interdisciplinary study elucidates 3-CMC effects and its associated risks, opening new objectives for future studies on CMC compounds to provide critical information to clinicians and the toxicological field.

Dementia is a progressive condition that affects cognitive and functional abilities. Psycho-motor agitation represents a frequent and challenging manifestation in People Living with Dementia (PLwD). This behavior contributes to heightened distress and increased risk of harm for patients, while posing a significant burden for caregivers, who must navigate the complexities of managing unpredictable and potentially harmful agitation episodes. Accurately predicting and promptly responding to agitation events is thus critical for enhancing the safety and well-being of PLwD. Leveraging artificial intelligence, tools can be used to monitor behavioral patterns and alert healthcare providers about potential agitation to facilitate timely and effective interventions. Despite the link between poor sleep quality and the likelihood of agitation, there remains a gap in utilizing sleep parameters for predictive analytics in this domain. This study explores the potential of integrating sleep and associated physiological data to predict the risk of agitation in dementia patients the next day, leveraging the Technology Integrated Health Management (TIHM) dataset. Our analysis reveals that the LightGBM model, enhanced with combined feature sets, delivers superior performance, achieving a weighted F1 score of 93.6% compared to standard baseline models. The findings underscore the value of incorporating sleep data into automated models and advocate for continued efforts to develop long-term agitation prediction methods. Full article

Background: The COVID-19 pandemic has had a profound impact on pediatric mental health, contributing to a global surge in psychiatric emergencies among children and adolescents. This study aimed to evaluate trends in pediatric emergency department (PED) visits for three key psychiatric conditions—anxiety disorders (ADs), self-injury behaviors (SIBs), and psychomotor agitation (PMA)—before and after the onset of the COVID-19 pandemic. Methods: We conducted a retrospective observational study at a tertiary pediatric hospital in Italy, analyzing all psychiatric presentations to the PED from 1 January 2018 to 31 December 2024. The data were divided into pre-COVID and post-COVID periods and included patient demographics, recurrence of visits, clinical features, hospital admissions, and pharmacological management. Diagnoses were confirmed by chart review. Results: Of 233,867 total PED visits, 1082 were due to primary psychiatric concerns. A marked increase in visits was observed postCOVID: SIB incidence rose from 3.6 to 15.1 per 10,000 visits (p < 0.0001), PMA from 9.4 to 17.8 (p < 0.0001), and AD from 17.7 to 21.6 (p = 0.018). SIB cases showed increased recurrence (from 3.4% to 27.4%, p = 0.004) and greater pharmacological intervention, whereas PMA was associated with a rise in heteroaggression (from 14.3% to 39.8%, p < 0.0001). Pharmacological treatment remained largely consistent, with benzodiazepines and neuroleptics most frequently used. The emerging use of intranasal ketamine was noted in select cases. Conclusions: This study highlights the increasing burden of pediatric psychiatric emergencies in the wake of the COVID-19 pandemic. The findings underscore the urgent need to implement standardized emergency care protocols, strengthen outpatient mental health services, and develop pediatric-specific pharmacological guidelines to improve outcomes in this vulnerable population.

Introduction: Psychomotor agitation represents a complex medical emergency, particularly challenging in prehospital settings. Since March 2020, the incidence of psychomotor agitation has significantly increased. Rationale: Emergency Medical Services (EMS) frequently serve as the first point of contact, bearing the critical responsibility of effectively managing these situations. Objective: This was to assess the feasibility and suitability of the intranasal route for administering pharmacological therapy in the prehospital management of patients experiencing psychomotor agitation. Materials and Methods: An integrative review of the literature was conducted to evaluate the use of the intranasal route for drug administration in patients with psychomotor agitation in prehospital settings. The review was carried out between September 2022 and July 2024. A total of 454 articles were identified, 15 of which met the inclusion criteria. These were supplemented by an additional 10 records, resulting in the analysis of 25 studies. Results: Seventeen studies outlined protocols for managing agitated patients, five described the correct technique for intranasal drug administration, and eleven identified drugs suitable for this route. Conclusions: The intranasal route is a safe, rapid, and accessible method for the pharmacological containment of agitated patients in prehospital settings, particularly for individuals who are uncooperative.

In this report, we document and analyze a case in which the Irkut virus (IRKV) (Mononegavirales: Rhabdoviridae) caused a fatal human case following a bat bite in June 2021. Unfortunately, the available data did not permit a detailed taxonomic classification of the carrier bat (Chiroptera). The event occurred in the southwestern part of the Sikhote-Alin mountain region (Russian Far East) covered by the Ussuri taiga forest. The symptoms of the illness began with the following: fever; pronounced psychomotor and motor agitation; tremor of the lower jaw and tongue; aphasia; dyslexia; and dysphagia. These rapidly developed, leading to a severe and fatal encephalitis. The patient was not vaccinated for rabies and did not receive rabies immunoglobulin. Using brain sections prepared from the deceased, molecular diagnostics were performed: immunofluorescence (polyclonal anti-rabies immunoglobulin) indicating the presence of the lyssavirus antigen; and RT-PCR indicating traces of viral RNA. Sectional material (brain) was used for whole-genome sequencing, resulting in a near-complete sequence of the lyssavirus genome. The obtained genomic sequence was identified as the Irkut virus. A comparative analysis of the new sequence and other currently available IRKV sequences (NCBI) revealed differences. Specifically, amino acid differences between antigenic sites in the isolate and those of the rabies vaccine strain used regionally were noted. The patient history and subsequent analysis confirm human IRKV infection following bat contact. Like other fatal cases of IRKV infection described earlier, this case occurred in the southern part of the Russian Far East. Two have occurred in the southwestern part of the Sikhote-Alin mountain region. This indicates the possible existence of an active, natural viral focus. Full article

Background: Autism spectrum disorder (ASD) is a persistent neurodevelopmental disorder frequently co-occurring with attention-deficit/hyperactivity disorder (ADHD) and behavior-related disorders. While behavioral therapy is the first-line option to manage the core symptoms of ASD, pharmacological therapy is sometimes needed to treat acute problems, such as agitation and aggressive behaviors. Recent guidelines recommend the use of neuroleptics to reduce psychomotor agitation in patients with ASD. However, as children with ASD are often drug-resistant, alternative treatments are often justified. Reports from the literature have indicated that intravenous valproate (IV-VPA) can be effective in reducing agitation in psychiatric patients, with a lower frequency of adverse events compared to conventional treatments. However, as the related findings are occasionally inconsistent, IV-VPA is not yet an approved option in the context of clinical psychiatry. We aim to improve knowledge of the IV-VPA treatment option for emergency psychiatric treatment in pediatric patients. Methods: We report the case of an 11-year-old boy suffering from a complex neurodevelopmental condition who experienced a psychotic episode with severe aggressive and disruptive behaviors and was successfully treated with IV-VPA. Furthermore, we provide an updated literature review on this topic. Conclusion: In our case, first-line therapies proved to be ineffective. To the contrary, IV-VPA led to safe and prompt clinical success, which is in line with other reports. Based on our literature review, IV-VPA can be highly effective and reduces the risk of adverse events that frequently occur with the use of high-dose standard medications in emergency psychiatry.

Due to their susceptibilities, neonates and infants face unique SARS-CoV-2 challenges. This retrospective study will compare the illness course, symptoms, biomarkers, and lung damage in neonates and infants with SARS-CoV-2 infection from February 2020 to October 2023. This study was conducted at two hospitals in Timisoara, Romania, using real-time multiplex PCR to diagnose and lung ultrasonography (LUS) to assess lung involvement. Neonates had a more severe clinical presentation, an increased immune response, and greater lung involvement. Neonates had more PCR-positive tests (p = 0.0089) and longer hospital stays (p = 0.0002). In neonates, LDH, CRP, and ferritin levels were higher, indicating a stronger inflammatory response. Reduced oxygen saturation in neonates indicates respiratory dysfunction. The symptoms were varied. Infants had fever, cough, and rhinorrhea, while neonates had psychomotor agitation, acute dehydration syndrome, and candidiasis. This study emphasizes individualized care and close monitoring for neonatal SARS-CoV-2 infections. Newborn lung ultrasonography showed different variances and severity levels, emphasizing the need for targeted surveillance and therapy. Newborns have high lung ultrasound scores (LUSS), indicating significant lung involvement. Both groups had initial lung involvement, but understanding these modest differences is crucial to improving care for these vulnerable populations. Full article

Aggressive behaviors of people with dementia pose a significant challenge to employees in nursing homes and aged care facilities. Aggressive behavior is a result of psychomotor agitation in dementia (BPSD). Globally, psychotropic interventions are the preferred treatment for BPSD. However, it is still unclear which psychotropic should be prescribed. The purpose of this systematic review is to compare pharmacological interventions for psychomotor agitation and psychosis symptoms. Method: The studies were extracted from databases, such as PubMed, OVID, and Cochrane, with a date restriction from 2000 to present, and in English. PRISMA steps were used to refine the extracted data. The RCTs extracted for this systematic review compared active ingredient medications to one another or to a placebo. Results: PRISMA was used to assess all selected trials comprehensively. Four trials are being conducted on quetiapine, two on haloperidol, one on olanzapine, three on risperidone, one on brexpiprazole, one on pimavanserin, and two on aripiprazole. Compared to typical antipsychotics, quetiapine showed tolerable adverse effects and did not worsen parkinsonism. Psychosis symptoms and behavioral improvements can be improved with haloperidol. Among elderly patients with psychosis, risperidone reduces angriness, paranoia, and aggression, as well as improves global functioning. As compared with other antipsychotics, aripiprazole provides a lower risk of adverse effects and demonstrated improvement in agitation, anxiety, and depression associated with psychosis. While olanzapine improves hostile suspiciousness, hallucinations, aggression, mistrust, and uncooperativeness, it worsens depression symptoms. Psychosis was treated effectively with pimavanserin without adverse effects on motor functions. Psychosis symptoms are well tolerated by brexpiprazole, but insomnia, headache, and urinary tract infections are common side effects. Conclusions: In this systematic review, we provide an overview of how to choose the correct antipsychotics and dosages for the management of BPSD and emphasize the importance of safe and conservative use of these drugs.

The restriction measures adopted to limit population movement in order to contain the COVID-19 pandemic contributed to a global public health system crisis. This retrospective study aimed at identifying changes in psychiatric admissions to Accident and Emergency Departments (A&Es) in a province in southern Italy during the first two years of the pandemic and was characterized by two different restriction levels (phases 2 and 3) compared to the pre-pandemic period (phase 1). We also investigated the role of socioeconomic deprivation (DI) on psychiatric admissions. The total number of patients admitted to the A&Es was 291,310. The incidence of admission for a psychiatric disorder (IPd) was 4.9 per 1000 admissions, with a significant younger median age of 42 [IQR 33–56] compared to non-psychiatric patients (54 [35–73]). The type of admission and type of discharge were factors related to the psychiatric admission to A&E, and their relationship was modified by the pandemic. In the first year of the pandemic, patients with psychomotor agitation increased compared to the pre-pandemic period (72.5% vs. 62.3%). In the period preceding the spread of SARS-CoV-2, the IPd was equal to 3.33 ± 0.19; after the pandemic started, there was an increase in the IPd: 4.74 ± 0.32 for phase 2 and 3.68 ± 0.25 for phase 3. The IPd was higher for psychiatric admissions from areas with a very low DI compared to areas with a low DI; however, during phase 2, this difference was reduced. In conclusion, an increase in admissions for psychiatric disease was observed during the initial spread of SARS-CoV-2. Patients who lived in the most deprived municipalities generally came to the A&Es less than others, probably because the patients and their families had less awareness of their mental health. Therefore, public health policies to address these issues are needed to reduce the pandemic’s impact on these conditions. Full article

Using Poland as an example, it was shown that 41.6% of the requests for intervention in 2016–2021 by Environmental Protection Inspections were related to odour nuisance. Further analysis of the statistical data confirmed that approximately 5.4% of wastewater treatment plants in the group of municipal facilities were subject to complaints. Detailed identification of the subject of odour nuisance at wastewater treatment plants identified hydrogen sulphide (H₂S), ammonia (NH₃) and volatile organic compounds (VOCs) as the most common malodorous substances within these facilities. Moreover, the concentrations of hydrogen sulphide and ammonia exceed the reference values for some substances in the air (0.02 mg/m³ for H₂S and 0.4 mg/m³ for NH₃). A thorough assessment of the properties of these substances made it clear that even in small concentrations they have a negative impact on the human body and the environment, and their degree of nuisance is described as high. In the two WWTPs analysed in Poland (WWTP 1 and WWTP 2), hydrogen sulphide concentrations were in the range of 0–41.86 mg/m³ (Long-Term Exposure Limit for H₂S is 7.0 mg/m³), ammonia 0–1.43 mg/m³ and VOCs 0.60–134.79 ppm. The values recognised for H₂S cause lacrimation, coughing, olfactory impairment, psychomotor agitation, and swelling of the cornea with photophobia. Recognition of the methods used in practice at WWTPs to reduce and control malodorous emissions indicates the possibility of protecting the environment and human health, but these solutions are ignored in most facilities due to the lack of requirements specified in legislation.

(1) Background: To systematically review evidence on the safety and efficacy of psychopharmacological treatments available for psychomotor agitation (PA) in children and adolescents. (2) Methods: Studies assessing the safety and efficacy of psychopharmacological treatments for acute PA in children and adolescents that were published between January 1984 and June 2022 on PubMed were systematically reviewed. We included: (i) papers that presented a combination of the search terms specified in the “Search strategy” sub-paragraph; (ii) manuscripts in English; (iii) original papers; (iv) prospective or retrospective/observational studies and experimental or quasi-experimental reports. The exclusion criteria were: (i) review papers; (ii) non-original studies including editorials and book reviews; (iii) studies not specifically designed and focused on the selected topic. (3) Results: We selected 42 papers: 11 case series (11/42, 26.19%), 8 chart reviews (8/42, 19.05%), 8 case reports (8/42, 19.05%), 6 double-blind placebo-controlled randomized studies (6/42, 14.29%), 4 double-blind controlled randomized studies (4/42, 9.52%), 4 open-label trials (4/42, 9.52%) and 1 case control (1/42, 2.38%). (4) Conclusions: The drugs most frequently used to treat agitation in children and adolescents were ziprasidone, risperidone, aripiprazole, olanzapine and valproic acid. Further studies are needed to evaluate the efficacy/safety ratio, considering the limited number of observations in this field. Full article

Psychomotor agitation is characterised by an increase in psychomotor activity, restlessness and irritability. People with psychomotor agitation respond by over-reacting to both intrinsic and extrinsic stimuli, experiencing stress and/or altered cognition. The objective of this study is to assess the clinical and sociodemographic profile of psychomotor agitation in patients with severe mental disorders. The study was carried out in Spain by means of multicentre cross-sectional convenience sampling involving 140 patients who had been admitted to psychiatric hospital units and had experienced an episode of psychomotor agitation between 2018 and 2021.Corrigan’s Agitated Behaviour Scale was used to assess psychomotor agitation. The results show that the predominant characteristic in psychomotor agitation is aggressiveness, which is also the most reported factor in patients with severe mental disorder. Patients who also have anxiety develop psychomotor agitation symptoms of moderate/severe intensity. The clinical and sociodemographic profile found in our study is consistent with other studies on the prevalence of psychomotor agitation. Full article

Emergence delirium (ED) is a postoperative complication in pediatric anesthesia characterized by perception and psychomotor disorder and has a negative impact on morbidity in the form of maladaptive behavior, which can last weeks after anesthesia. Patients with developed ED present with psychomotor anxiety, agitation, and are at higher risk of unintentional extraction of an intravenous cannula, self-harm and nausea and vomiting. The described incidence of ED varies between 25–80%, with a higher prevalence among children younger than 6 years of age. We aimed to determine the incidence of ED in pediatric patients (>1 month) after general anesthesia in the post-anesthesia care unit (PACU), using Paediatric Anaesthesia Emergence Delirium (PAED) score, Watcha score and Richmond agitation and sedation scale (RASS). The incidence of ED was the highest in the PAED score with cutoff ≥10 points (89.0%, n = 1088). When using PAED score >12 points, ED incidence was 19.3% (n = 236). The lowest incidence was described by Watcha and RASS scores, 18.8% (n = 230) vs. 18.1% (n = 221), respectively. The threshold for PAED ≥10 points seems to give false-positive results, whereas the threshold >12 points is more accurate. RASS scale, although intended primarily for estimation of the depth of sedation, seems to have a good predictive value for ED. Full article

The aim of this study is to examine the relationship between chronotype, classroom behaviour and school performance in 140 healthy school-age children attending various levels of education during the 1st cycle during 2021 in Portugal. In this cross-sectional and quantitative study, the Chronotype Questionnaire for Children (to assess the chronotype) and the Conners Scale—a reduced version was presented to the teachers (to assess behaviours such as excessive movement, inattention and oppositional behaviours)—were used. The methodology of this study followed a comparative method since the independent variables were not controlled, and therefore, it was still possible to compare the differences between the morning and evening groups. Statistical methods were used such as multivariate analyses, inter-item correlations and reliability tests, and descriptive tests were used for the percentile analysis. The sample was divided into three groups based on the identification of the chronotype—morning, intermediate and evening types—to further study the relationship between these chronotypes, their academic performance and classroom behaviour were studied. A multivariate analysis of variance revealed that there was a higher rate of oppositional behaviour in the morning type and no differences in the school performance during the two semesters (covering all of the school periods) regarding the chronotype effect, even with the analysis of regression parameters and covariates. On the other hand, the morning-type children showed a greater amount of motor agitation and impulsivity after controlling for the gender covariate. Age had an effect on the chronotype, after controlling for the covariate parental education. This study highlights the need for further research on the chronotype of the morning children in order to regulate their behaviour. The data that were obtained raise questions that have not been yet considered in the literature in the area of education and infant development. Full article

People with dementia are more likely to develop delirium. We conducted a brief literature search and give a pragmatic overview of the key issues. Making rational and safe prescribing decisions is highly influenced by organisational culture and embedded staff practices. Comprehensive assessment for unmet physical, psychological, and social needs is an important intervention in itself. Taking a broad overview of possible pharmacological interventions should include stopping inappropriate medications and prescribing for key drivers of the underlying causes of delirium. Prescribing psychotropic medications may be indicated where there is significant distress or risk to the person with dementia and risk to those around them. It is vital to consider the dementia subtype and, where possible, involve family and friend carers in the decision-making process. Medications should be prescribed at the lowest possible dose for the least amount of time after carefully weighing risks versus benefits and documenting these. While these cases are challenging for staff and families, it can be rewarding to improve the quality of life and lessen distress for the person with dementia. There are also opportunities for informing family and friend carers, educating the wider multidisciplinary team, and promoting organisational change. Full article
