Abstract
Mitochondria are cytoplasmic organelles having a fundamental role in the regulation of neural stem cell (NSC) fate during neural development and maintenance.During embryonic and adult neurogenesis, NSCs undergo a metabolic switch from glycolytic to oxidative phosphorylation with a rise in mitochondrial DNA (mtDNA) content, changes in mitochondria shape and size, and a physiological augmentation of mitochondrial reactive oxygen species which together drive NSCs to proliferate and differentiate. Genetic and epigenetic modifications of proteins involved in cellular differentiation (Mechanistic Target of Rapamycin), proliferation (Wingless-type), and hypoxia (Mitogen-activated protein kinase)-and all connected by the common key regulatory factor Hypoxia Inducible Factor-1A-are deemed to be responsible for the metabolic shift and, consequently, NSC fate in physiological and pathological conditions.Both primary mitochondrial dysfunction due to mutations in nuclear DNA or mtDNA or secondary mitochondrial dysfunction in oxidative phosphorylation (OXPHOS) metabolism, mitochondrial dynamics, and organelle interplay pathways can contribute to the development of neurodevelopmental or progressive neurodegenerative disorders.This review analyses the physiology and pathology of neural development starting from the available in vitro and in vivo models and highlights the current knowledge concerning key mitochondrial pathways involved in this process.

Abstract
Benzodiazepine (BDZ) addiction is a widespread and multifaceted phenomenon. For many patients, especially females, the concomitant use of other drugs also increases their risk of QTc prolongation, possibly leading to complications such as seizures and even sudden death. However, the relationship between BDZ use and QTc prolongation is currently unclear. The present study aims to examine patterns of polysubstance use among a sample of Italian adults with BDZ dependence in relation with their QTc prolongation risk. We used Latent Class Analysis (LCA) on data collected from 251 inpatients of the Addiction Medicine Unit in Verona to group patients into three classes according to their substance use and their QTc prolongation risk. Results showed no significant relationship between QTc prolongation and BDZ use in any of the classes considered. We conclude that BDZs, even if used long-term and at high dosages, can be considered safe in terms of cardiovascular complications for patients.

Abstract
Nicotine addiction is a widespread, worldwide epidemic, causing six million deaths per year. A large variety of treatments for smoking cessation are currently available, including Cytisine, which is a promising drug due to its low cost and high safety levels. Notwithstanding the important amount of research on tobacco addiction treatments, smoking remains one of the most difficult substance use disorders to treat, probably also due to the fact that pharmacological treatment often overlooks other maintaining factors in this addiction, such as sensory impact and cue reactivity. To address this gap in both treatment protocols and scientific literature, we propose a study protocol in which we will compare the effects of combining Cytisine with Nirdosh, a herbal tobacco substitute, to Cytisine only in two groups of patients (C + N and C) who will also undergo exposure to four different virtual reality settings that will assess the importance of environmental cues. We will further assess mood and craving in the two samples, and include a control group taken from the general population. We expect the C + N group to report a more positive mood and a lower sensitivity to tobacco-related environmental cues.

Abstract
Abstract
Background
The Academic Research Consortium High Bleeding Risk (ARC-HBR) criteria have been proposed to stratify the bleeding risk of patients undergoing percutaneous coronary intervention (PCI). While most criteria were established, 4 criteria have been proposed on a de novo basis.
Purpose
We assessed the prevalence and prognosis of new ARC-HBR criteria in a contemporary, prospective, multicenter, quality-improvement registry of all-comers patients with acute coronary syndromes.
Methods
Between 2016 and 2020, consecutive subjects were enrolled; baseline characteristics and medications were prospectively collected, and patients were followed-up at 1 year. All clinical events (including bleeding) were adjudicated by an independent committee. All 17 ARC-HBR criteria were individually evaluated by reviewing patients' charts.
Results
Of the 2804 patients enrolled, 782 (28.0%) met the ARC-HBR definition and 47 (6%) of them experienced a major BARC 3 or 5) bleeding at 1-year. HBR patients had a significantly higher risk of BARC 3–5 bleedings (HR for: 3.07; 95% CI: 2.02–4.67; p<0.0001; Fig. 1A), BARC 2–5 (HR: 1.845; 95% CI: 1.4–2.42; p<0.0001). Fig. 1B indicates the proportion of patients meeting each criterion. Age, (moderate or severe) chronic kidney disease, (moderate or severe) anemia and oral anticoagulant therapy included 88% of HBR patients.
The 4 new ARC-HBR criteria, all together, were present in only 1.7% of our population: 1.0% was planned for major surgery while on dual antiplatelet therapy, 0.5% had a recent intracranial hemorrhage/ictus or brain arteriovenous malformations, 0.1% had hepatic cirrhosis with portal hypertension and 0.1% had a recent surgery or trauma. In a multivariable Cox regression analysis including individual ARC-HBR criteria, only CKD (major and minor criteria), anemia (major and minor criteria) and cancer were the independent predictors of BARC 3–5 events with a concordance-index for this model of 0.698 (p<0.001). In a second model including only CKD (major criterion), anemia (major criterion), age and oral anticoagulation therapy, all these criteria were independent predictors of BARC 3–5 events with a concordance index of 0.674 (pmodel<0.001 for the model) (Fig. 2).
Conclusion
Almost one third of contemporary ACS patients was at HBR according to the ARC-HBR definition and these patients presented a significantly higher risk of bleedings at 1-year. The most common 4 criteria (age, CKD, anemia, and oral anticoagulant therapy) allowed the identification of 88% of HBR patients. The newly proposed HBR criteria were extremely rare and therefore challenging to validate and of uncertain clinical utility. These data may inform and simplify clinical decision making and provide priority for future directions of HBR definitions.

Abstract
Abstract
Background
Sodium-glucose transporter 2 inhibitors (SGLT2-i) have demonstrated substantial improvement in clinical outcomes for patients with heart failure (HF) and chronic kidney disease (CKD) with or without diabetes mellitus (DM). Prescription patterns and outcome of SGLT2-i candidates in patients hospitalized for an acute coronary syndrome (ACS) are less well established.
Purpose
We aimed to assess the proportion of candidates to SGLT2-i and to characterize their clinical outcome in a contemporary, prospective, multicenter, quality-improvement study of all-comers patients with ACS. We also aimed to ascertain prescriptions of SGLT2-i at discharge.
Methods
Between 2018 and 2020, subjects were enrolled in the study; baseline characteristics and medications were prospectively collected, and patients were followed-up at 1 year. Subjects were considered candidates to SGLT2-i if any of the following were: (i) known (medically treated) or new (HbA1c >6.5%) diagnosis of type 2 DM; (ii) left ventricular systolic dysfunction (LVSD; new or known left ventricular ejection fraction <40%) or clinical HF; (iii) CKD (estimated glomerular filtration rate 25–74 mL/min/m2, according to DAPA-CKD trial eligibility).
Results
Of the 2804 consecutive ACS patients enrolled, 798 (28.5%) had new or known DM and only 10 were already on SGLT2-I at baseline. Additionally, 1,098 (39.2%) patients qualified for SGLT2-i prescription as having known or new LVSD or HF, and 803 (28.6%) as having CKD. (Fig. 1A) Overall, these 1,767 (63.1%) SGLT2-i candidates had substantially higher hazard of death as compared to no candidate (Hazard Ratio [HR] at 1-year: 6.82; 95% Confidence Interval: 4.32–10.8; p<0.001; Fig. 1B) and each indication to SGLT2-i independently predicted death at 1 year (HR: 2.30/2.11/3.06; 95% CI: 1.78–2.97/1.62–2.74/2.35–3.97; all p<0.0001; for DM, HF, CKD, respectively; Fig. 2). At discharge, only 18 (1.0% of the candidates) were prescribed with SGLT2-i and, of those with DM, having a diabetological consultation before discharged modestly but significantly increased the likelihood of being discharged with SGLT2-i (4.3% vs. 6.6%; p=0.0015).
Conclusion
Most (two out of three) contemporary ACS patients are candidates to SGLT2-i therapy, and they have a significant and substantial higher risk of mortality at 1-year as compared to no candidates. Current prescription rates are still extremely low (1%) and highlight opportunity for quality improvement and multidisciplinary decision-making.

Abstract
Young adults exhibit greater sensitivity than adults to nicotine reinforcement, and Attention Deficit Hyperactivity Disorder (ADHD) increases the risk for early-onset smoking. We investigated the correlation between ADHD Self-Report Scale (ASRS) scores and smoking, evaluated the prevalence of ADHD symptomatology (not diagnoses) in smokers and non-smokers and its comorbidity with benzodiazepine and gambling addictions. A total of 389 young adults from 14 schools in Northern Italy fill out a survey and the Adult ADHD Self-Report Scale (ASRS). A total of 15.2% of subjects tested positive at the ASRS, which correlated with smoking; moreover, smokers had twice the probability of testing positive at the ASRS. ADHD symptomatology, especially when comorbid with tobacco abuse, is an important condition to monitor because early nicotine exposure could be a gateway for other addictive behaviors.

Abstract
BACKGROUND The COVID-19 pandemic and control measures may have had an impact on unpleasant emotions experimented during the lockdown (LD). This may have increased the number of hours spent online and could have impacted the quality of the enacted behavior, in terms of loss of control of Internet use. In this online survey, we were interested in measure how much loss of control was perceived regarding online gambling, online shopping, the fruition of online pornographic content and web navigation. DESIGN AND METHODS The online survey was carried out during the COVID-19 pandemic in the post-lockdown and 1232 subjects participated in the survey. In the participating sample, healthcare workers (HW) were 43.1% of the sample, of which 18.7% were directly involved in the Coronavirus emergency, and 52.3% of the sample is not a HW. Only 0.6% of the sample gambled online and 37.5% of those reported losing control of their gambling mode. Most of the sample shopped online during the LD (70.1%), but only 7.2% of those lost control by buying and/or spending more than what they had set themselves. RESULTS Significant data emerged showing that those who lost control while online shopping also lost control regarding the amount of time spent online (p<0.001); 21.6% of the sample, reported making use of online pornographic material during LD, 4.7% of them stated that the frequency increased and 5.1% reported losing control by having spent more money or more time than what was intended. Finally, 44.7% of the sample have experienced loss of control during the web navigation. Furthermore, during the LD 67.8% of the sample reports having experienced unpleasant emotions. Of these, 8.4% state that they enacted behaviors such as online gambling, online shopping, online pornographic material viewing and web navigation to counter their negative emotions. Interestingly, we found a correlation between loss of control during web navigation and online shopping and the emotional states "upset", "scared" and "restless" (p<0.05). CONCLUSION To conclude, there was no significant increase in potentially addictive behaviors, nor an increase in loss of control of these behaviors when enacted online. However, the loss of control in online shopping and web navigation was significantly correlated to the unpleasant emotional states of nervousness, fear and restlessness, whereas those who reported feeling strong and able to handle the situation experienced a lower loss of control in their web navigation. These correlations may suggest that these online behaviors may act as modulators of unpleasant emotional states.

Abstract
The considerable prominence of internet addiction (IA) in adolescence is at least partly explained by the limited knowledge thus far available on this complex phenomenon. In discussing IA, it is necessary to be aware that this is a construct for which there is still no clear definition in the literature. Nonetheless, its important clinical implications, as emerging in recent years, justify the lively interest of researchers in this new form of behavioral addiction. Over the years, studies have associated IA with numerous clinical problems. However, fewer studies have investigated what factors might mediate the relationship between IA and the different problems associated with it. Ours is one such study. The Italian version of the SCL-90 and the IAT were administered to a sample of almost 800 adolescents aged between 16 and 22 years. We found the presence of a significant association between IA and two variables: somatization (β = 7.80; p < 0.001) and obsessive-compulsive symptoms (β = 2.18; p < 0.05). In line with our hypothesis, the results showed that somatization predicted the relationship between obsessive-compulsive symptoms and IA (β = -2.75; t = -3.55; p < 0.001), explaining 24.5% of its variance (ΔR 2 = 1.2%; F = 12.78; p < 0.01). In addition, simple slopes analyses revealed that, on reaching clinical significance (+1 SD), somatization showed higher moderation effects in the relationship between obsessive-compulsive symptoms and IA (β = 6.13; t = 7.83; p < 0.001). These results appear to be of great interest due to the absence of similar evidence in the literature, and may open the way for further research in the IA field. Although the absence of studies in the literature does not allow us to offer an exhaustive explanation of these results, our study supports current addiction theories which emphasize the important function performed by the enteroceptive system, alongside the more cited reflexive and impulsive systems.

Abstract
The pharmacokinetics of the extemporaneous combination of low doses of ketamine and propofol, known as 'ketofol', frequently used for emergency procedures in humans to achieve safe sedation and analgesia was studied in cats. The study was performed to assess propofol, ketamine and norketamine kinetics in six female cats that received ketamine and propofol (1:1 ratio) as a loading dose (2 mg/kg each, IV) followed by a continuous infusion (10 mg/kg/h each, IV, 25 min of length). Blood samples were collected during the infusion period and up to 24 h afterwards. Drug quantification was achieved by HPLC analysis using UV-visible detection for ketamine and fluorimetric detection for propofol. The pharmacokinetic parameters were deduced by a two-compartment bolus plus infusion model for propofol and ketamine and a monocompartmental model for norketamine. Additional data were derived by a noncompartmental analysis. Propofol and ketamine were quantifiable in most animals until 24 and 8 h after the end of infusion, respectively. Propofol showed a long elimination half-life (t(1/2λ2) 7.55 ± 9.86 h), whereas ketamine was characterized by shorter half-life (t(1/2λ2) 4 ± 3.4 h) owing to its rapid biotransformation into norketamine. The clinical significance of propofol's long elimination half-life and low clearance is negligible when the drug is administered as short-term and low-dosage infusion. The concurrent administration of ketamine and propofol in cats did not produce adverse effects although it was not possible to exclude interference in the metabolism.

Abstract
The pharmacokinetics of teicoplanin were evaluated in 10 healthy sheep. After intravenous injection it showed monophasic behaviour, with a short mean (sd) elimination half-life (5 [0.24] hours). After intramuscular injection its bioavailability was 100 per cent but it was absorbed slowly; its elimination half-life was satisfactorily slow (9.23 [0.74] hours). Its efficacy was evaluated in 26 crossbreed sheep with milk positive to strains of Staphylococcus aureus, coagulase-negative staphylococci and Streptococcus agalactiae, and clinical signs of disease. In 19 of them a single intramuscular dose of 6 mg/kg bodyweight resulted in a complete resolution of the clinical signs, and no microorganisms were detected in milk by the fifth day; in the other seven sheep, with more severe intramammary infections, three consecutive daily intramuscular doses of 6 mg/kg bodyweight were necessary. There were no local or systemic side effects and no relapses during 30 days after the treatments in any of the sheep.

Abstract
PRIMARY OBJECTIVE The study aimed at developing a new valid measure of disability in TBI outpatients. RESEARCH DESIGN AND METHODS The Rasch model (Winsteps 3.45 software, 2005) was adopted to achieve a linear measure, unidimensional and reliable. The predictive capacity with respect to return to school or job was also tested (logistic regression, STATA 8.0 software, 2004). EXPERIMENTAL INTERVENTIONS Either tests of Attention, Memory and Verbal Fluency or the FIM were administered to 160 TBI ambulatory outpatients (52 women, age 14-72, 2-117 months after trauma, 111 cases with coma > or = 1 week). Fifty of them (31%) had returned to school or job. MAIN OUTCOMES AND RESULTS A new scale called MINDFIM could be successfully developed. It includes three cognitive and four FIM motor items (Grooming, Upper Body Dressing, Bathing and Tub/Shower Transfer). The scale raises the ceiling affecting existing instruments. The summated scores are predictive of return to community (74% correct classification). CONCLUSIONS MINDFIM is valid and useful measure of disability in TBI outpatients.

Abstract
REASONS FOR PERFORMING STUDY The selective COX-2-inhibitor nimesulide is used extra-label in equine veterinary practice as an anti-inflammatory agent. However, there are no data on which to base the rational use of the drug in this species. OBJECTIVES To determine the effective COX selectivity of nimesulide in the horse, and suggest a suitable dosing schedule. METHODS The pharmacokinetics of nimesulide in the horse after oral administration (1 mg/kg bwt), and oral and i.v. administration (1.5 mg/kg bwt) were investigated, effects of feeding status on bioavailability determined, and plasma protein binding of the drug and its principal metabolites measured. Compartmental and noncompartmental pharmacokinetic analyses were performed. The plasma concentration-time profile was used, together with in vitro literature data on nimesulide inhibition of COX isoforms, to determine the effective COX selectivity of nimesulide in the horse, and suggest a suitable dosing schedule. RESULTS AND CONCLUSIONS The findings suggest that 1.5 mg/kg bwt may produce adequate clinical effects, and the dosing interval should be 12-24 h depending on condition severity. However, at that dose, the concentration in the animal exceeds the in vitro IC50 for both isoforms, so that COX-1/COX-2 selectivity is lost and side-effects due to COX-1 inhibition are a possibility. Nimesulide should therefore be used with caution in equine clinical practice.
