Brain doping: stimulants use and misuse among a sample of Italian college students

Introduction. The non-medical use of prescription stimulants (NMUPS) has become of great interest for its diffusion among university students, engaged in NUMPS to cope with the increasing load of academic stress. This consumption has been more throughoutly investigated in the U.S. due to its increasing trend. However, NMUPS has been reported also in Europe. The aim of this cross-sectional study was to examine stimulants misuse in an Italian area, identifying possible developments of the phenomenon in Italy.Methods.To evaluate academic and extra-academic NMUPS (Methylphenidate and Amphetamines), an anonymous multiple-choice questionnaire was administrated to a representative sample of Bachelor’s and Master’s degrees students attending a University of North of Italy.Data elaboration and Confidence Interval 95% were performed with Excel software 2013, while Fisher's exact tests with GraphPad INSTAT software.Results. Data from 899 correctly compiled questionnaires were analyzed in this study.11.3% of students reported NMUPS with an apparent greater use by students aged 18-22 years (73.5%) and without any gender predominance (p: n.s.). 57,8% of students used stimulants at most five times in six months, while the most frequent academic and extra-academic motives for use were respectively to improve concentration while studying (51.0%) and sports performance (25.5%). NMUPS was higher among working students than non-working ones (p <0.05), suggesting a stimulants use to cope with stress by the first ones.Conclusion. These data suggest that NMUPS is quite relevant in the North of Italy, requiring preventive and monitoring measures, besides future analysis with a longitudinal multicenter study

Working Memory abilities, attachment relationships and learning process in children of primary school age: an empirical research

Several studies underline a definite link between “working memory†(WM) and the learning process (deficit and learning disorder in children). WM abi-lities mainly affect written language learning and arithmetic learning. According to studies related to the Attachment Theory, it is possible to rationalize that child with a secure attachment to the caregiver and/or to the teacher have higher skills in school adaptability. In this study—based on previous pilot study (Del Villano, Ce-cere, Sapuppo, & Caviglia., 2011)—the relationship between: cognitive test (WM measurement test), learning test and the student’s attachment style (both with his caregivers and his teacher) have been empirically evaluated. This pilot study was performed in several of the primary schools in Campania Italy between 2009 and 2011. The selected sample was composed of 80 children 6-7 years old (38 Female and 42 Male) who, after parental and school consent, were tested by the tools de-scribed in the main body of this research paper. The pilot study shows an absence of linguistic deficit, and a relationship between cognitive abilities and the learning le-vel achieved in reading and mathematical calculation, furthermore it has shown a modulation effect of the attachment on the relationship between the WM ability and MT calculation and reading tests. This modulation effect is more evident if we consider the unsecure or disorganized attachment, especially if we consider the data accumulated with reference to the attachment to the teacher. Our research was conducted with the sole intention to widen the sample and make the outcomes more valid and reliable. The recruited sample was composed of 130 children age 6-7 who, after parenentalt and school consent, were tested with the TVL -Linguistic As-sessment Test , the short version of AWMA (Automated Working Memory As-sessment), the SAT-Separation Anxiety Test, both family and school versions, and the Reading Trials MT -AC-MT 6-11- Calculation Ability Assessment Test. The re-sults underline the absence of deficit or malfunctions in the subjects’ linguistic de-velopment, a significant connection between the learning performances and the verbal and visual-spatial trials assessed with the AWMA, and a moderating effect of the attachment style upon the connection itself

Real-world clinical and psychosocial outcomes among people with mild or moderate haemophilia A treated on-demand in the Italian CHESS II cohort: a real-world data analysis

© 2024 Giancarlo Castaman et al., published by SciendoBackground: The burden of severe haemophilia A (HA) has been studied extensively owing to the higher bleeding frequency and associated treatment requirements, leaving a clear unmet need for research focused on the burden of mild and moderate HA. Aims: This study sought to characterise the clinical and psychosocial burden of mild and moderate HA in the Italian cohort of the CHESS II study. Methods: This was a retrospective analysis of clinical and psychosocial outcomes in a cohort of male adults (≥18 years old) with mild or moderate HA who participated in the cross-sectional CHESS II study (October 2019-November 2020). Treatment patterns, acute and chronic clinical outcomes and mental health indicators were collected via physician-completed forms. Psychosocial outcomes related to impact of HA on social activities, exercise, opportunities, and lifestyle were collected via a participant self-complete questionnaire. All results were reported descriptively. Results: A total of 113 people with haemophilia A (PwHA) were included, 79 (70%) with moderate HA and 34 (30%) with mild HA, with mean age of 41.4 and 36.6 years, respectively. No one in the sample was receiving a prophylaxis at the time of data capture, with factor VIII use in the 12 months prior reported in 30% and 29% of moderate and mild PwHA, respectively. Ninety-one PwHA (81%) experienced ≥1 bleeding event in the preceding 12 months. People with moderate HA had higher mean annual bleed rate (2.9 vs. 1.1, respectively) and higher prevalence of chronic pain (74% vs. 35%), anxiety (20% vs. 12%), and/or depression (15% vs. 3%). Target joints were reported in 22% and 12% of moderate and mild PwHA, and problem joints in 51% and 12%, respectively. Of 113 participants, 44 (39%) completed the self-complete form (moderate HA, 57%; mild HA, 43%). Overall, 40% vs. 10% of those with moderate vs mild HA reported reducing or giving up social activities, 44% vs. 21% reducing or giving up exercise, 36% vs. 26% missing out on opportunities, and 48% vs. 26% reported HA impacted their lifestyle. Conclusion: Moderate PwHA from the Italian CHESS II cohort appeared to have greater clinical morbidity and lifestyle impact than mild PwHA. Psychosocial outcomes were also worse among moderate PwHA, but significant burden was also observed among mild PwHA. These findings, and the absence of prophylactic treatment in the sample examined, highlight that improving management for potentially undertreated mild/moderate PwHA may aid the avoidance long-term clinical morbidity and negative psychosocial impact.Acknowledgements: This paper reports a retrospective study in which no human participants or animals are directly involved.

Managing a Mass CO Poisoning: Critical Issues and Solutions From the Field to the Hyperbaric Chamber

Carbon monoxide acute intoxication is a common cause of accidental poisoning in industrialized countries and sometimes it produces a real mass casualty incident. The incident described here occurred in a church in the province of Verona, when a group of people was exposed to carbon monoxide due to a heating system malfunction. Fifty-seven people went to the Emergency Department. The mean carboxyhemoglobin (COHb) level was 10.1\ub15.7% (range: 3-25%). The clinicians, after medical examination, decided to move 37 patients to hyperbaric chambers for hyperbaric oxygen (HBO) therapy. This is the first case report that highlights and analyses the logistic difficulties of managing a mass carbon monoxide poisoning in different health care settings, with a high influx of patients in an Emergency Department and a complex liaison between emergency services. This article shows how it is possible to manage a complex situation with good outcome. (Disaster Med Public Health Preparedness. 2016;page 1 of 5)

Stress biology:Complexity and multifariousness in health and disease

Preserving and regulating cellular homeostasis in the light of changing environmental conditions or developmental processes is of pivotal importance for single cellular and multicellular organisms alike. To counteract an imbalance in cellular homeostasis transcriptional programs evolved, called the heat shock response, unfolded protein response, and integrated stress response, that act cell-autonomously in most cells but in multicellular organisms are subjected to cell-nonautonomous regulation. These transcriptional programs downregulate the expression of most genes but increase the expression of heat shock genes, including genes encoding molecular chaperones and proteases, proteins involved in the repair of stress-induced damage to macromolecules and cellular structures. Sixty-one years after the discovery of the heat shock response by Ferruccio Ritossa, many aspects of stress biology are still enigmatic. Recent progress in the understanding of stress responses and molecular chaperones was reported at the 12th International Symposium on Heat Shock Proteins in Biology, Medicine and the Environment in the Old Town Alexandria, VA, USA from 28th to 31st of October 2023.</p

Search for dark matter produced in association with bottom or top quarks in √s = 13 TeV pp collisions with the ATLAS detector

A search for weakly interacting massive particle dark matter produced in association with bottom or top quarks is presented. Final states containing third-generation quarks and miss- ing transverse momentum are considered. The analysis uses 36.1 fb−1 of proton–proton collision data recorded by the ATLAS experiment at √s = 13 TeV in 2015 and 2016. No significant excess of events above the estimated backgrounds is observed. The results are in- terpreted in the framework of simplified models of spin-0 dark-matter mediators. For colour- neutral spin-0 mediators produced in association with top quarks and decaying into a pair of dark-matter particles, mediator masses below 50 GeV are excluded assuming a dark-matter candidate mass of 1 GeV and unitary couplings. For scalar and pseudoscalar mediators produced in association with bottom quarks, the search sets limits on the production cross- section of 300 times the predicted rate for mediators with masses between 10 and 50 GeV and assuming a dark-matter mass of 1 GeV and unitary coupling. Constraints on colour- charged scalar simplified models are also presented. Assuming a dark-matter particle mass of 35 GeV, mediator particles with mass below 1.1 TeV are excluded for couplings yielding a dark-matter relic density consistent with measurements

Measurement of the dependence of transverse energy production at large pseudorapidity on the hard-scattering kinematics of proton-proton collisions at √s=2.76 TeV with ATLAS

The relationship between jet production in the central region and the underlying-event activity in a pseudorapidity-separated region is studied in 4.0 pb-1 of s=2.76 TeV pp collision data recorded with the ATLAS detector at the LHC. The underlying event is characterised through measurements of the average value of the sum of the transverse energy at large pseudorapidity downstream of one of the protons, which are reported here as a function of hard-scattering kinematic variables. The hard scattering is characterised by the average transverse momentum and pseudorapidity of the two highest transverse momentum jets in the event. The dijet kinematics are used to estimate, on an event-by-event basis, the scaled longitudinal momenta of the hard-scattered partons in the target and projectile beam-protons moving toward and away from the region measuring transverse energy, respectively. Transverse energy production at large pseudorapidity is observed to decrease with a linear dependence on the longitudinal momentum fraction in the target proton and to depend only weakly on that in the projectile proton. The results are compared to the predictions of various Monte Carlo event generators, which qualitatively reproduce the trends observed in data but generally underpredict the overall level of transverse energy at forward pseudorapidity

Measurements of the charge asymmetry in top-quark pair production in the dilepton final state at s √ =8 TeV with the ATLAS detector

Measurements of the top-antitop quark pair production charge asymmetry in the dilepton channel, characterized by two high-pT leptons (electrons or muons), are presented using data corresponding to an integrated luminosity of 20.3  fb−1 from pp collisions at a center-of-mass energy s√=8  TeV collected with the ATLAS detector at the Large Hadron Collider at CERN. Inclusive and differential measurements as a function of the invariant mass, transverse momentum, and longitudinal boost of the tt¯ system are performed both in the full phase space and in a fiducial phase space closely matching the detector acceptance. Two observables are studied: AℓℓC based on the selected leptons and Att¯C based on the reconstructed tt¯ final state. The inclusive asymmetries are measured in the full phase space to be AℓℓC=0.008±0.006 and Att¯C=0.021±0.016, which are in agreement with the Standard Model predictions of AℓℓC=0.0064±0.0003 and Att¯C=0.0111±0.0004
