What impact can hospitalization environment produce on the ANS functioning in patients with Unresponsive Wakefulness Syndrome? - 24-hour monitoring.

Objectives: Studies showed that the recovery of patients with Unresponsive Wakefulness Syndrome (UWS) is also correlated to the recovery of circadian rhythms. In this study, we observed the correlations between patients with UWS biometrical and ambient parameters. Methods: A dedicated monitoring system was realized to record and correlate the level of noise and luminosity with biometric Heart Rate (HR), Heart Rate Variability (HRV) and Breath Rate (BR) parameters. Eleven patients with UWS were recruited and monitored for 13 ± 7 days. Correlation of ambient and biometric parameters was analyzed by Spearman's test. Wilcoxon's test was used to compare the biometric parameters in two different moments of daily activity in the rehabilitation unit (night and day). Patients showed a moderate negative or positive correlation between biometric and ambient parameters. Results: Significant differences between night and morning (0.0001 < p ≤ 0.001) were found for HR, HRV and BR in seven, five and four patients, respectively, at Wilcoxon's test. HR and BR were higher during the night while HRV was lower. Conclusion: In patients with UWS, lower HRV and higher HR and BR during the night might be indicative of interference in sleep/wake cycles. The modifications of the environment surrounding the patient due to the unit procedures of the staff and/or some interaction modalities of the relatives may have an effect on residual endogenous mechanisms of self-regulation. However, differences between night and day in the biometrical parameters are not necessarily linked to the changes in the environment care unit.

New Italian guidelines for malaria prophylaxis in travellers to endemic areas.

BACKGROUND AND METHODS: As a consequence of the rapid evolution of malaria prophylaxis recommendations throughout the world, the Italian Society of Tropical Medicine (SIMET-Società Italiana di Medicina Tropicale) has set up a working group in charge of preparing a new national guideline. Other scientific societies interested in the topic were also involved in the project. RESULTS AND CONCLUSIONS: The group stated that awareness about malaria risk and characteristics, as well as protection from mosquito bites, are recommended for all travellers visiting malaria-endemic countries. The risk and benefit of malaria chemoprophylaxis must be carefully balanced before prescribing drugs: the disease-related risk must outweigh the possibility of drugs' side effects. As a general rule, malaria pills are the first choice for travellers to high-risk areas, such as sub-Saharan Africa, Eastern India, Myanmar, Eastern Indonesia, Papua New Guinea and, with some limitations, South-East Asia, and the Amazon part of Venezuela, Guyana and French Guyana. However, several other factors, such as itinerary, season, duration of trip, availability of insect bite protection, pre-existing conditions and compliance, must be taken into account. In low-risk areas, stand-by emergency treatment is the first option. In minimal-risk areas and in Plasmodium vivax areas, a prompt diagnosis only is advised (Central America, South America outside the Amazon basin, Middle East, China, Thailand, Nepal). Recommendations may be modified when particular groups of travellers are concerned, such as long-term residents, visiting friends and relatives, patients with pre-existing conditions, pregnant women and children.

Access to medically-assisted procreation: the withdrawal of paternal consent in the maze of law n. 40/2004.

Abstract: The law (No.40/2004) stipulates that consent to Medically Assisted Procreation (MAP) remains irrevocable post ovum fertilization. Cryo-preservation introduces complexities, enabling embryo implantation requests after a couple's separation and the dissolution of the original parenthood plan. Constitutional Court Ruling No.161 in 2023 affirmed that the prohibition of revoking consent to MAP aligns with the Italian Constitution and the jurisprudence of the European Court of Human Rights. This delicate equilibrium of conflicting interests upholds human freedom, allowing consent revocation prior to ovocyte fertilization. Permitting revocation until implantation could inflict more significant harm: the infertile woman can in fact miss the opportunity to become a mother, impacting her psychophysical well-being and freedom of self-determination. Moreover, the embryo loses the chance to live, remaining in cryopreservation, which violates its dignity. Addressing this issue requires thorough communication by medical profession-als to inform couples about the limitations on consent revocation. An element of objectivity in terms of standards and evidence-based guidelines, from which norms must originate, is of utmost importance. Relying on broadly shared rules, especially at the international level, is vital in light of the unremitting scientific advances in MAP, as in other areas of medicine, which will open up new opportunities for which current legal/regulatory frameworks are inadequate.

Consequences of COVID-19 restrictions on adolescent mental health and drug abuse dynamics.

The COVID-19 pandemic has hit elderly people the hardest in terms of severity and mortality. However, it is also evident that children and adolescents have been significantly impacted and experienced major disruptions in their lives. The psychological, mental, and developmental repercussions have been major and have led to a reshaping of drug abuse dynamics and substance addiction. The authors have outlined a narrative review of the major issues affecting adolescents and their mental well-being by clarifying the lingering effects and pandemic aftermath, especially on drug abuse, developmental aspects, and behavioral addiction. The unique traits of adolescent risk factors have been outlined, in order to identify areas to be prioritized for future strategies. Possible repercussions on juvenile crime linked to social estrangedness and disrupted interactions have been briefly explored as well. All such aspects are highly meaningful and relevant from a medicolegal perspective as well. The looming mental health crisis involving youngsters will have to be confronted by fine-tuning and optimizing mental health care services, building on current experiences, raising awareness, and eliminating the stigma that often comes with mental issues. Healthcare systems should look at the current scenario as an opportunity to improve care delivery to eliminate access inequalities and stigmatization of mental issues and raise awareness for the benefit and well-being of all. Similarly, law enforcement, lawmakers, and the judiciary will have to account for such factors, too, as will economic policy-makers. In that regard, a set of defining criteria has been framed in order to provide a degree of objectivity when meeting the unique challenges of the pandemic for youth mental health, in a comprehensive and tailored fashion.

Experience of vaccination against invasive bacterial diseases in Veneto region (north east Italy).

The goal of this study was to describe and comment the experience of the Veneto Region in the bacterial invasive disease. Vaccination coverage was 93% against pneumococcus and 95% against haemophilus influenzae type B. Regard to meningococcus C the coverage rate was 90.1% In children, 81% at 6 years of age and 78.2% at 15 years. The preliminary data of an active surveillance of invasive bacterial diseases show that the Streptoccoccus pneumoniae was the main agent involved and that its consequences were particularly serious in elderly subjects. With regard to Neisseria meningitidis, we observed a substantial reduction in the number of cases due to serogroup C and a concomitant rise in the percentage of cases due to serogroup B. The suspension of mandatory vaccination should be maintained, the monitoring of vaccination coverage and the active surveillance proved to be a very good assessment tools.

[Increasing childhood immunization coverage by establishing structured relationships with pediatricians and family practitioners]. / Aumentare le coperture vaccinali in età pediatrica creando rapporti strutturali con la pediatria di famiglia.

An immunization strategy can take advantage of various tools, among which the pediatrician and family practitioner These figures, have been assigned the role of accompanying the child and his/her family throughout development. One of the objectives of this role is also to take a major part in the support of immunization coverage of infants, especially in light of the sospension of required immunizations in the Veneto Region. For this reason it is necessary to open dialogue on immunizations together with pediatricians and family physicians. In addition, training of these professional figures, together with healtcare operators who work in the immunization clinics, has allowed the formation and standardization of the network, as the persons who attend the immunization clinics are no longer passive users but persons who require information exchange in order to make an informed choice about immunizations for their children. Surveillance of vaccination coverage is a useful tool for evaluating the trend in vaccination refusals, and in particular it takes into consideration the motivation behind the refusal to adhere to the polio vaccine recommendations even if for now the coverage is maintained above 95%. Concluding, another strong point for the immunization program is "Genitori Più" which finds its continuity with the Regional Prevention Plan.

Identity and reproductive rights of transgenders: are current legal and ethical frameworks soon to be outdated? Medicolegal implications of potentially life-changing decisions.

Abstract: The level of recognition that transgender individuals (i.e. those whose gender does not match the sex assigned at birth) enjoy in our societies has certainly made giant strides. Still, there is no denying that the far-reaching ramifications arising from choices about one's gender expression do affect vital aspects of identity in school, workplaces, and the community, and should be clearly defined and addressed by laws and policies. One of the arguments most commonly used by supporters of transgender rights relies on the concept of inalienable human rights, including the rights to live safely, freely, and without fearing discrimination. The authors have set out to succinctly outline and elaborate on the dynamics that have been shaping the legal reco-gnition of transgender individuals in light of the unique legal, social and ethical complexities that such an evolution entails. Moreover, as assisted reproduction technologies make considerable progress and innovations open up new horizons for fertility preservation and restoration, it is worth exploring how such advance can play a role in upholding the reproductive rights of transgender patients who wish to achieve parenthood, and how counseling ought to be implemented taking into account the psychological traits of transgender patients and the implications of every choice they make.

The evolution of European legislation on doping: new challenges in the age of NPS.

The fight against doping in sport, formally started in 1960 with the constitution of the International Olympic Committee (IOC) and culminated in 1999 with the birth of the World Anti-Doping Agency (WADA), commissioned to chair various activities, including the publication of the annual list of prohibited substances and methods for doping. In Europe, as early as 1967, the Committee of Ministers of the Council of Europe adopted a resolution to stigmatise the intake of substances foreign to the body for the sole purpose of artificially and unfairly influencing sports performance. In 2002, the Council of Europe adopted an Additional Protocol to the 1989 Strasbourg Convention against Doping to ensure mutual recognition of doping controls and to strengthen the enforcement of the Convention. In Italy, the Law of 14 December 2000 n. 376 "Discipline of the health protection of sports activities and the fight against doping", defines doping as "the administration or intake of drugs or biologically or pharmacologically active substances and the adoption or submission to medical practices not justified by pathological conditions and suitable to modify the psychophysical or biological conditions of the organism in order to alter the athletic performance of athletes". The same law regulates the use of drugs or biologically or pharmacologically active substances and update an annual list in agreement with WADA. The article aims to analyse the legislation from a national perspective, offering as complete a view as possible of the current situation.

Research on supernumerary embryos: the challenge of recon- ciling opposing interests and fast-evolving technologies.

ABSTRACT: The paper addresses the issue of the legality and ethical admissi-bility of invasive experiments on embryos and the correlated one of the degree of legal protection and dignity to be recognized for human embryos, particularly in light of the growing importance that scientific research on embryonic stem cells has been gaining from the clinical and biomedical standpoints in the therapeutic treatments of diseases so far considered incurable, in the interest of public health. Furthermore, the issue of experimentation on cryopreserved supernumerary human embryos is still extremely polarizing, which makes it harder to arrive at shared solutions. The author hopes for a broad-ranging debate at the international level, for the ultimate purpose of achieving shared regulatory frameworks.

The issue of infertility in times of COVID-19: what do we know about it?

ABSTRACT: Couple infertility constitutes a major source of concern and even distress for those involved, affecting roughly 50-80 million people in the world, according to World Health Organization data. There is no denying that medical and technological advancements in the field of as-sisted reproductive technology (ART) are among the greatest and most beneficial achievements of modern medicine. Countless couples have been able to achieve parenthood who in the past could not have, thanks to ART. Infertility itself used to be deemed insurmountable, especially when arising from uterine conditions (referred to as absolute uterine factor infertility, AUFI), neoplastic conditions or major complications affecting reproductive organs during previous pregnancies. The inability to have children is often considered by couples as a failure severely impacting their relationships, due to the unfulfilled biological potential in regard to parenting. However, in addition to its significance as a social problem, infertility is a medical issue which requires a strict and clearly defined path of diagnosis and treatment, particularly in times of COVID-19, when access to essential care has often been delayed with potentially harmful repercussions for patients seeking to achieve parenthood or to keep their fertility.

The Traveller's Risk Perception (TRiP) questionnaire: pre-travel assessment and post-travel changes.

BACKGROUND: Travellers' risk perception is a key component of travel risk assessment because it influences the adequate implementation of safety precautions. The aims of this study are to validate a tool to analyse travellers' risk perception to identify which factors can influence it and how it changes upon return. METHODS: The Traveller's Risk Perception (TRiP) questionnaire was developed and administered to outpatients before and after travel in three travel clinics. A principal component analysis (PCA) was performed to validate the questionnaire and multivariate regression analysis was used to evaluate the effect of travellers' characteristics on the risk scores. RESULTS: A total of 1020 travellers completed the questionnaire. PCA identified two latent factors: 'generic-disseminated risks' and 'specific-circumstantial risks'. Cronbach's α was acceptable (0.76 and 0.70, respectively). The 'generic-disseminated risks' dimension scored higher than the 'specific-circumstantial risks' (p<0.001). The items with the highest scores were insect bites, gastrointestinal disorders and malaria. The mean scores were significantly lower after the travel for all items but one. CONCLUSIONS: The TRiP questionnaire is a valid and reliable tool for rating travellers' perceptions. Staff in travel clinics should be trained to systematically assess travellers' risk perception in order to tailor the consultation according to specific information needs.

Where is West Nile fever? Lessons learnt from recent human cases in northern Italy.

West Nile disease in humans has been detected for the first time in Italy in two regions, Emilia-Romagna and Veneto. We conclude that also West Nile fever cases should be specifically targeted by surveillance.

[Overcoming mandatory vaccination policy: first steps]. / Il superamento dell'obbligo vaccinale: prime esperienze.

Steps toward overcoming mandatory vaccination policy follow two main tracks: scientific and administrative. Scientific course checks starting conditions of the project in Veneto Region and monitors the effects of policy. Thanks to sensibilization regional programs and partecipation to national campaigns of vaccination, Veneto Region has achieved high coverage for all actively promoted vaccinations. Specific projects has been implemented in order to improve vaccination system quality, particularly with regard to infectious diseases and vaccine adverse events surveillance, training workers and informatization. On 23rd March 2007 Veneto Region passed the regional law number 7 called "Sospensione dell'obbligo vaccinale per l'età evolutiva" becoming in force for children born since January 1st 2008. The law provides for the institution of a scientific committee having the task of monitoring both vaccination coverage and preventable infectious diseases incidence after overcoming mandatory vaccination policy.

An observational study on the epidemiology of respiratory tract bacterial pathogens and their susceptibility to four injectable beta-lactam antibiotics: piperacillin, piperacillin/tazobactam, ceftazidime and ceftriaxone.

Bacterial infections of the respiratory tract account for a large proportion of total medical consultations in general practice. In recent years, antibiotic resistance has increased alarmingly in a number of bacterial species that are common causes of these infections. The aim of this observational study was to determine the antibiotic resistance of microbial agents isolated from patients with acute or acutely exacerbated respiratory infections. Subjects recruited as potential sources of bacteria were either outpatients seen in a number of specialized clinics and hospital practices, or hospitalized patients. Overall, 648 consecutive patients (67% male, mean age 48.1+/-27.0 years) with infection of the upper or lower respiratory tract were observed during a 13-month period. A total of 551 pathogenic microbial strains were isolated and tested for their in vitro susceptibility to piperacillin, piperacillin/tazobactam, ceftazidime, and ceftriaxone. Among all isolates, the four most frequent pathogens were Pseudomonas aeruginosa (132 isolates, 24%), Streptococcus pyogenes (99 isolates, 18%), Staphylococcus aureus (93 isolates, 17%), and Klebsiella pneumoniae (46 isolates, 8%). The susceptibility of gram-positive isolates ranged from 97.5% to 95.1%, and no remarkable difference was found in the antibacterial activity of tested b-lactam antibiotics. The susceptibility of gram-negative isolates to piperacillin and piperacillin/tazobactam was also similar: 96.5% and 97.1%, respectively. In contrast, differences were found between piperacillin (or piperacillin/tazobactam) and either ceftazidime (p=0.003) or ceftriaxone (p<0.0003) in gram-negative isolates. We conclude that, despite the extensive use of beta-lactam antibiotics (piperacillin, ceftazidime, and ceftriaxone) in medical practice during the past three decades, the susceptibility of the most common pathogens involved in the etiology of upper and lower respiratory tract infections to these antibiotics is still high. In particular, bacterial resistance developed by gram-positive organisms against piperacillin is negligible and not alarming.

Effect of atrial natriuretic factor on arterial baroreceptor control of heart rate and blood pressure in conscious rats.

The effects of atrial natriuretic factor (ANF) on arterial baroreceptor control of heart rate and of blood pressure were examined in conscious normotensive rats chronically instrumented with arterial and venous catheters, by measuring (1) the pulse interval responses to four intravenous boluses of phenylephrine and four intravenous boluses of nitroprusside, reflex sensitivity being calculated as the slope of the linear relationship between pulse interval and mean arterial pressure (nine rats); (2) the pressor response to right common carotid occlusion (balloon-in-cuff occluder) in eight rats with aortic and left carotid baroreceptor denervation. The study was performed before and during a non-hypotensive infusion of ANF. Atrial natriuretic factor increased the bradycardic responses to phenylephrine by 90% but reduced the tachycardic response to nitroprusside by 67% (P less than 0.01 for both) and left the pressor response to carotid occlusion unaffected (-7%, NS). It is concluded that ANF modulates the arterial baroreceptor reflex in a complex fashion, with opposite responses to arterial baroreceptor stimulation and deactivation, and different responses for the cardiac and vascular component of the reflex.
