Uncontrolled ingestion of alcohol has dramatic consequences on the entire organism that are also associated with the oxidation process induced by alcohol and elevate radical oxygen species. Resveratrol, a nonflavonoid phenol, shows well-documented antioxidant properties. We investigated the potential antioxidant ability of this natural compound in a mouse model of alcohol addiction.We administered (per os) for 60 d 10 mg · kg-1 · d-1 of resveratrol in alcoholic adult male mice. Oxidative stress was evaluated by measuring serum-free oxygen radicals defense and free oxygen radical levels. Resveratrol metabolites were measured in the serum of mice that were administered with resveratrol. Finally, the effect of resveratrol on the alcohol-induced alteration of brain-derived neurotrophic factors (BDNF) in the liver was investigated.Prolonged consumption of resveratrol strongly counteracts serum radical oxygen species formation caused by chronic alcohol intake without effects on natural, free oxygen radical defense. The presence of resveratrol metabolites in the serum only of animals supplemented with resveratrol potentiates the evidence that the antioxidant effect observed is due to the ingestion of the natural compound. Moreover, resveratrol supplementation can counteract alcohol-induced BDNF elevation in the liver, which is the main target of organ alcohol-induced damage.The consumption of resveratrol through metabolite formation may play a protective role by decreasing free radical formation and modulating the BDNF involved in hepatic disruption induced by chronic alcohol consumption. Further investigation into the mechanism underlying the protective effect could reinforce the potential use of resveratrol as a dietary supplement to prevent damage associated with chronic alcohol abuse.

The number of children living in socio-economically disadvantaged neighborhoods in developed countries is constantly growing, resulting in important implications for children's development, physical and psychological health and increased future disparities. In this study, we explored several key elements of children living in poor neighborhoods, such as demographic characteristics, access to public health assistance and school, and availability of housing and basic hygienic conditions.The study included 711 children aged 0-17 years referring to primary care services in the suburbs of the city of Rome, Italy.Most children were born in Italy, while almost none of their parents were. Nearly 60% of the children did not have access to basic pediatric care, causing possible misdiagnosis and delayed treatment for acute and chronic conditions. A smaller percentage of the children did not have access to basic housing (8%) and hygienic facilities, such as heating, running water, and refrigerator (3.2%), leading to malnutrition, isolation and poor physical and psychological development.This study confirms a critical condition for children living in disadvantaged neighborhoods, whose vulnerability is further worsened by the limited access to paediatric health assistance and, in some cases, to basic facilities with a severe impact on their physical and psychological development.

Introduction: The number of migrants living in Europe is growing rapidly. The PROTECT project is a national study conducted among refugees and migrants in the Lazio region, Italy from February 2018 to September 2021 to evaluate their otolaryngological, dental, and ophthalmic health status. This article reports the results of this study with a special focus on otolaryngological conditions and diseases. Materials and methods: A total of 3023 participants were included in the project. Data on the participants’ demographic factors, migration status, and otolaryngological history were collected using a questionnaire. Each patient underwent clinical ear, nose, and throat examination, and the main otolaryngological conditions and diseases were noted. Results: nearly two-thirds of participants were males (68.1%). The mean age was 31.6 ± 13.1. Most of the participants were born in Nigeria, followed by Bangladesh, Pakistan, Somalia, Mali, and Gambia. The prevalence of chronic noise exposure was 5.2%. Unilateral hearing loss was reported by 6.5% of the subjects, and bilateral hearing loss by 3.6%. The most frequent symptoms reported in the questionnaire were snoring (10.4%), nasal obstruction (5.9%), vertigo (5.0%), otalgia (4.5%), and tinnitus (4.2%). At the clinical examination, the most frequent findings were nasal septum deviation (25.2%), ear wax (6.5%), hypertrophic palatine tonsils (5.3%), and tympanic membrane perforation (1.3%). Conclusions: the PROTECT project allowed for the evaluation of otolaryngological, dental, and ophthalmological conditions in over 3000 migrants, giving them the possibility to access specialist care.

Binge drinking is associated with several adverse effects in multiple organs. This study aimed at evaluating the effects of a binge-like-drinking on the vestibulo-oculomotor reflex (VOR) using the video Head Impulse Test (vHIT) and the functional Head Impulse Test (fHIT).Eleven healthy men (age range 32-35 years) with moderate drinking habits and no history of vestibular dysfunction were enrolled. A preliminary assessment of breath alcohol concentration (BrAC) to check for zero alcohol value and a pre-intake evaluation of VOR using the vHIT and the fHIT were carried on. Then, the subjects were asked to take drinks with different alcohol content (8-40% ethanol by volume) according to their choice, consuming at least 5 standard drinks. Volunteers stopped drinking after 3 h. After a further 30 min, post-intake BrAC measurements and VOR analysis were repeated.After alcohol intake, vHIT recorded an overall significant reduction of VOR gain (0.82 ± 0.07 on both sides) although the outcomes were below the normal range only in the four subjects with the highest blood alcohol levels. The post-intake fHIT outcomes were substandard in 9 participants, with a significant deterioration in performance (% of exact answers = 84.54 ± 11.05% on the left, 83.18 ± 14.53 on the right).Binge drinking severely affects VOR; fHIT seems more sensitive than vHIT in the assessment of VOR function for complex vestibular lesions, such as those determined by ethanol, suggesting that fHIT could support vHIT in vestibular dysfunction assessment.

Ethanol exposure during gestation is an early life stressor that profoundly dysregulates structure and functions of the embryonal nervous system, altering the cognitive and behavioral development. Such dysregulation is also achieved by epigenetic mechanisms, which, altering the chromatin structure, redraw the entire pattern of gene expression. In parallel, an oxidative stress response at the cellular level and a global upregulation of neuroendocrine stress response, regulated by the HPA axis, exist and persist in adulthood. This neurobehavioral framework matches those observed in other psychiatric diseases such as mood diseases, depression, autism; those early life stressing events, although probably triggered by specific and different epigenetic mechanisms, give rise to largely overlapping neurobehavioral phenotypes. An early diagnosis of prenatal alcohol exposure, using reliable markers of ethanol intake, together with a deeper understanding of the pathogenic mechanisms, some of them reversible by their nature, can offer a temporal "window" of intervention. Supplementing a mother's diet with protective and antioxidant substances in addition to supportive psychological therapies can protect newborns from being affected.

Midwives are multifaceted healthcare professionals whose competence spectrum includes a large variety of knowledge and skills going from antenatal care to education and research. The aim of this review is to suggest the future challenges midwives are going to face in the upcoming decade of this Century. COVID-19 and other infections will reasonably impact healthcare workers all over the world. Midwives are frontline healthcare professionals who are constantly at risk of contagion as their job implies close contact with women, physical support and hand touch. Also, menstruation waste plays a large role in the pollution of waters, severely impacting hygiene in the developing countries and fueling climate change. Appropriate disposal of used menstrual material is still insufficient in many countries of the world especially because of lack of sanitary education on girls. As educators, midwives will be more involved into preventing inappropriate disposal of menstrual hygiene devices by educating girls around the world about the green alternatives to the commercial ones. Despite the evidences about the fertility decrement that occurs with aging, women keep postponing reproduction and increasing their chance being childless or suffering complications related to the advanced maternal age. Teen pregnancies are as well an important issue for midwives who will be called to face more age-related issues and use a tailored case to case approach, enhancing their family planning skills. Another crucial role of midwifery regards the information about the risk of drinking alcohol during gestation. Alcohol assumption during pregnancy is responsible for serious damage to the fetus causing a wide range of pathological conditions related to Fetal Alcoholic Spectrum Disorder, leading cause of mental retardation in children of western countries. On the whole, midwives have demonstrated their willingness to expand their practice through continuing professional development, and through specialist and advanced roles especially in preventive and educational positions.

Vulnerability, as a phenomenon of analysis, has long been the subject of extensive social and economic policy reflections, aimed at planning social welfare interventions to support the areas most exposed to the effects of the economic crisis, especially with reference to the presence of potentially weaker segments of the population [...]
