Sliding mode control algorithms for wheel slip control of road vehicles

Sliding mode control approaches are presented in this paper for the wheel slip control of road vehicles. The major design requirement for the controllers is to make the wheel slip ratio follow a desired value, while guaranteeing that the sliding mode control is stabilizing. Its robustness in front of matched and unmatched uncertainties and data transmission delays is assessed in simulation. In the present paper different algorithms of first and second order type and integral or non integral nature are discussed. Simulation results are reported and analyzed, putting into evidence the superior performance, in the considered automotive context, of the integral sliding mode control

© 2022 Published by Elsevier Ltd on behalf of International Society for the Study of Emerging Drugs. This is an open access article under the CC-BY-NC-ND license (http://creativecommons.org/licenses/by-nc-nd/4.0/)Introduction: Somatic symptom disorder (SSD) is a mental disorder that involves one or more physical symptoms (e.g. palpitations, dizziness, diarrhoea, limb weakness, pain, and pseudo neurological symptoms) accompanied by one or more thoughts, feelings, and/or behaviours related to the somatic symptom(s) resulting in significant distress and/or dysfunction lasting for more than 6 months. At now the SSD can be refractory to psychiatric intervention including antidepressants, antiepileptics, and antipsychotics as well as the effectiveness of many of these treatments is limited. The objective of this study was to report the effectiveness of a third-generation antipsychotic drug brexpiprazole for treatment of a case of SSD together with the serotonin selective reuptake inhibitor (SSRI) fluvoxamine. Methods: A single case study of a 59-year-old female with SSD was here performed. Findings: After 4 weeks of treatment brexpiprazole, together with lamotrigine and fluvoxamine, was here effective in decreasing both depressive and anxiety symptoms, normalising previous unusual thought contents and of related behaviours. The patient reported an overall good response and started to function again in important domains of life. No adverse events occurred. Conclusion: To our knowledge, this is the first case showing Brexpiprazole effective for the treatment of a case of SSD as add-on to other drugs.Peer reviewedFinal Published versio

Could Cariprazine Be a Possible Choice for High Functioning Autism? A Case Report

© 2023 by the authors. Licensee MDPI, Basel, Switzerland. This is an open access article distributed under the terms of the Creative Commons Attribution License (CC BY), https://creativecommons.org/licenses/by/4.0/This case report was conducted by searching for the following keywords on PubMed: High Functioning Autism, Autism Spectrum Disorder, cariprazine, aripiprazole, partial agonist antipsychotic, DRD2/DRD3. High Functioning Autism (HFA) is a neurodevelopmental disorder characterized by the core symptoms of autism spectrum disorder (ASD) with average intellectual abilities, behavioral symptoms such as irritability, hyperactivity, aggressiveness and mood symptoms. HFA is not a term used in the Diagnostic and Statistical Manual of mental disorders (DSM), but it is commonly used to identify patients diagnosed with Autistic Disorder (AD) or Pervasive Developmental Disorder-Not Otherwise Specified (PDD-NOS) with average or above average intellectual abilities. Several factors are involved in HFA development, including environmental and genetic factors. In particular, over the last several decades, dopaminergic signaling system dysfunction has been highlighted as being responsible for behavioral patterns. Nowadays, symptoms of ASD lack a specific pharmacological treatment. The only medications approved by the Food and Drug Administration (FDA) for symptoms associated with ASD, in particular the irritability, are risperidone and aripiprazole. According to the hypothesis that dopamine receptor DRD2 and DRD3 might be involved in impulsive behavior, stereotypy, repetitive behaviors and language impairment, cariprazine could be a therapeutic option. This molecule is primarily characterized by DRD3 partial agonism and serotonin 5-HT1A partial agonism, with a lower ability to activate DRD2 than other third-generation antipsychotics, such as aripiprazole. We have reported here a case study of treatment of HFA with cariprazinePeer reviewe

The benzydamine experience: a systematic review of benzydamine abuse

Submitted 25 August 2020. Revised 14 December 2020. Accepted 19 December 2020. Abstract published online 13 January 2021. Full Article 19 November 2021.Background: Both prescription and over-the-counter (OTC) drugs recently emerged among novel psychoactive substances (NPS) being reported as ingested for recreational purposes. Among them, benzydamine (BZY), normally prescribed as an OTC anti-inflammatory drug, is reportedly being diverted and recreationally used. Objective: The aim of this study was to investigate how the misuse of BZY has been reported, illustrating its psychotropic molecular mechanism, and studying its psychopathological effects. Methods: We firstly conducted a systematic review of the literature concerning the abuse of BZY and its effects. For data gathering purposes, both PRISMA and PROSPERO guidelines were followed. All research methods were approved by PROSPERO (identification code CRD42020187266). Second, we analysed BZY-related data from the European Monitoring Agency (EMA) Adverse Drug Reactions (ADRs) database recorded during 2005-2020 regarding its abuse. Results: Eleven articles, published during 1997-2019, were included in our systematic review, including five case reports, four surveys, and two retrospective case series analyses. While nine articles dealt with a recreational use of BZY, two described an oral overdose of the drug. When specified, dosages of BZY consumed ranged from 500 to 1500mg. The EMA dataset contained three cases of BZY abuse. Conclusion: Results from the systematic review showed BZY might be diverted for typical hallucinogenic properties which occur at high dosages. Healthcare professionals should be warned about a possible misuse/abuse of a commonly prescribed anti-inflammatory drug and be vigilant when prescribing it. Physicians working in emergency units should know that psychotic symptoms may be related to BZY abuse.Peer reviewe

Recreational Drug Misuse and Its Potential Contribution to Male Fertility Levels’ Decline: A Narrative Review

© 2022 by the authors. Licensee MDPI, Basel, Switzerland. This article is an open access article distributed under the terms and conditions of the Creative Commons Attribution (CC BY) license (https://creativecommons.org/licenses/by/4.0/)Recreational drug intake may be associated with a range of medical untoward consequences, including male infertility. However, as the related evidence is still limited, the main outcome of this review is to provide a better understanding of the existence of any association between recreational drug misuse and male fertility levels’ decline. Whilst searching the MEDLINE/PubMed, a comprehensive overview of the literature regarding male infertility and substances of abuse (e.g., phytocannabinoids, opiates/opioids, stimulants, ‘herbal highs’, psychedelics, and ‘novel psychoactive substances) was here undertaken. Due to the paucity of robust, high-quality, empirical, human studies, a narrative strategy was here preferred over a systematic approach. Relevant data are qualitatively analyzed and presented in a table. Although most available evidence is in support of a detrimental role of cannabis on human spermatogenesis, a few remaining studies failed to document any effect of this drug on seminal quality, and it is not clear to which extent this drug impacts fertility rates/time to pregnancy. The current understanding of the impact of opiate-, cocaine- and amphetamine/stimulant-misuse on human reproduction is widely unknown, and most studies dealing with this matter represent only an extrapolation of data derived from specific clinical circumstances. Although the message of ‘no smoking, no alcohol and no street drugs’ should always be offered as good health advice to all patients seeking medical help for fertility issues, robust scientific clinical evidence in support of a direct detrimental impact of recreational drugs on spermatogenesis is scant to date.Peer reviewe

New Psychoactive Substances and Suicidality: A Systematic Review of the Current Literature

Submitted 23 April 2021. Minor revisions requested 31 May 2021. Revisions submitted 3 June 2021. Accepted 3 June 2021. Epub 6 June 2021.Background and Objectives: Over the past twenty years a large number of New Psychoactive Substances (NPS) has entered and modified the recreational drug scene. Their intake has been associated with health-related risks, and especially so for vulnerable populations such as people with severe mental illness, who might be at higher risk of suicidality or self- injurious behaviour. This paper aims at providing an overview of NPS abuse and effects on mental health and suicidality issues, performing a literature review of the current related knowledge, thereby identifying substances that more than others are linked to suicidal behaviours. Materials and Methods: A comprehensive and updated overview of the literature regarding suicidality and NPS categories has been provided. An electronic search was performed, including all papers published up to March 2021, using the following keywords "NPS" OR "new psychoactive substances" OR "novel psychoactive substances" OR "synthetic cannabinoids" OR "phenethylamines" OR "synthetic cathinones" OR “tryptamines” OR “piperazines” OR “new synthetic opioids” OR “designer benzodiazepines”) AND ("suicide" OR "suicidality") NOT review NOT animal on the PubMed, Cochrane Library, and Web of Science online databases. Results: Suicidality and self-injurious behaviour appear to be frequently associated with some NPS such as cathinones, synthetic cannabinoids, and new synthetic opioids. Results are organised according to substances recorded. Conclusion: The growing use of NPS has become a significant clinical issue, posing increasing concern and challenges for clinicians working in both mental health and emergency departments. Thus, considering the associations between NPS and suicidality or self-injurious behaviours, areas where suicide-prevention efforts and strategies might be focused are the early detection, monitoring and restriction of NPS.Peer reviewe

Focus on Over-the-Counter Drugs' Misuse: A Systematic Review on Antihistamines, Cough Medicines, and Decongestants

© 2021 Schifano, Chiappini, Miuli, Mosca, Santovito, Corkery, Guirguis, Pettorruso, Di Giannantonio and Martinotti. This is an open-access article distributed under the terms of the Creative Commons Attribution License (CC BY). https://creativecommons.org/licenses/by/4.0/Background: Over the past 20 years or so the drug misuse scenario has seen the emergence of both prescription-only and over-the-counter (OTC) medications being reported as ingested for recreational purposes. OTC drugs such as antihistamines, cough/cold medications and decongestants, are reportedly the most popular in being diverted and misused. Objective: Whilst the current related knowledge is limited, the aim was here to examine the published clinical data on OTC misuse, focusing on: antihistamines (e.g., diphenhydramine, promethazine, chlorpheniramine, and dimenhydrinate); dextromethorphan (DXM)- and codeine-based cough medicines; and the nasal decongestant pseudoephedrine. Methods: A systematic literature review was carried out with the help of Scopus; Web of Science databases; and the related grey literature. For data gathering purposes, both the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) and PROSPERO guidelines were followed (PROSPERO identification code CRD42020209261). Results: After completion of the selection, eligibility and screening phases, some 92 articles were here taken into consideration; case reports, surveys, and retrospective case series analyses were included. Findings were organised according to the specific OTC recorded. Most articles focussed here on DXM (n=54) and diphenhydramine (n=12). When specified, dosages, route(s) of administration, toxicity symptoms (including both physical and psychiatric ones), and outcomes were here reported. Conclusion: Results from the systematic review showed that the OTC misusing issues are both widespread worldwide and popular; vulnerable categories include adolescents and young adults, although real prevalence figures remain unknown, due to a lack of appropriate monitoring systems. Considering the potential, and at times serious, adverse effects associated with OTC misusing issues, healthcare professionals should be vigilant and ad hoc preventative actions should be designed and implemented.Peer reviewe

Therapeutic Potentials of Ketamine and Esketamine in Obsessive–Compulsive Disorder (OCD), Substance Use Disorders (SUD) and Eating Disorders (ED): A Review of the Current Literature

The obsessive–compulsive spectrum refers to disorders drawn from several diagnostic categories that share core features related to obsessive–compulsive disorder (OCD), such as obsessive thoughts, compulsive behaviors and anxiety. Disorders that include these features can be grouped according to the focus of the symptoms, e.g., bodily preoccupation (i.e., eating disorders, ED) or impulse control (i.e., substance use disorders, SUD), and they exhibit intriguing similarities in phenomenology, etiology, pathophysiology, patient characteristics and clinical outcomes. The non-competitive N-methyl-D-aspartate receptor (NMDAr) antagonist ketamine has been indicated to produce remarkable results in patients with treatment-resistant depression, post-traumatic stress disorder and OCD in dozens of small studies accrued over the past decade, and it appears to be promising in the treatment of SUD and ED. However, despite many small studies, solid evidence for the benefits of its use in the treatment of OCD spectrum and addiction is still lacking. Thus, the aim of this perspective article is to examine the potential for ketamine and esketamine in treating OCD, ED and SUD, which all involve recurring and intrusive thoughts and generate associated compulsive behavior. A comprehensive and updated overview of the literature regarding the pharmacological mechanisms of action of both ketamine and esketamine, as well as their therapeutic advantages over current treatments, are provided in this paper. An electronic search was performed, including all papers published up to April 2021, using the following keywords (“ketamine” or “esketamine”) AND (“obsessive” OR “compulsive” OR “OCD” OR “SUD” OR “substance use disorder” OR “addiction” OR “craving” OR “eating” OR “anorexia”) NOT review NOT animal NOT “in vitro”, on the PubMed, Cochrane Library and Web of Science online databases. The review was conducted in accordance with preferred reporting items for systematic reviews and meta-analyses (PRISMA) guidelines. The use and efficacy of ketamine in SUD, ED and OCD is supported by glutamatergic neurotransmission dysregulation, which plays an important role in these conditions. Ketamine’s use is increasing, and preliminary data are optimistic. Further studies are needed in order to better clarify the many unknowns related to the use of both ketamine and esketamine in SUD, ED and OCD, and to understand their long-term effectiveness.Peer reviewedFinal Published versio

An Italian survey of opioids misuse: Epidemiological and psychopathological aspects

© 2021 Published by Elsevier Ltd on behalf of International Society for the Study of Emerging Drugs. This is an open access article under the CC BY-NC-ND license, http://creativecommons.org/licenses/by-nc-nd/4.0/Objective Opioid abuse is a worrying reality especially in the US. The increase in the prescription of opioids in Europe poses the risk of a possible increase in the number of abusers also in Italy. The aim of the study is to evaluate the abuse of opioids in the youth population and to evaluate possible correlations with some psychopathological aspects. Methods A survey, conducted from July 2019 to March 2020, about the use of opioids was spread to a group of subjects aged between 18 and 40 years. A socio-demographical investigation and psychometric scales evaluating internet game addiction, gaming online, quality of life and general psychometric features were administrated. Results Nine-hundred and thirteen subjects completed the survey. Seventeen-five subjects (8.21%) have used one opioid at least once in their lifetime. Weak correlations were found between codeine and morphine intensity of use and sleep disturbance, cigarette smoked per day, while codeine correlates with the number of coffees taken per day and somatization. Conclusion Although the data of this survey do not show high percentages of use in Italy (8.21% of the sample have used one of the listed opioids at least once in their lifetime), the correlations founded confirm the literature data already present highlighting the need for constant monitoring of this phenomenon.Peer reviewedFinal Published versio
