    Introduction Children living with parents who harmfully consume alcohol might experience more life events, in particular negative, than children living with parents who do not harmfully consume alcohol. They also primarily use less adaptive coping styles and often demonstrate lower resilience. No studies evaluated whether coping styles or psychological well-being might influence the risk of life events occurrence in children living with parents who harmfully consume alcohol. Methods Forty-five children living with parents who harmfully consume alcohol and 45 children living with parents who do not harmfully consume alcohol, matched for sex and age, were assessed via the Appendix Life Events of the Minnesota Multiphasic Personality Inventory-Adolescent, the Coping Inventory for Stressful Situations, and the Psychological Well-Being scales. Results Children living with parents who harmfully consume alcohol had more life events in the 6-month period before the assessment, mostly negative and neutral, and lower levels of psychological well-being than children living with parents who do not harmfully consume alcohol. The risk of having experienced at least one negative or neutral life event was higher in children living with parents who harmfully consume alcohol than in their peers and in those with lower psychological well-being. The risk of having had a positive life event was not related to parents' consumption of alcohol but to avoidant coping and low self-acceptance behaviours. Conclusions Children living with parents who harmfully consume alcohol need interventions aimed at improving psychological well-being to protect them from life events, especially from negative ones

    Phthalic acid esters (PAEs) are recognized endocrine disruptors. Detection of PAEs in semen from idiopathic infertile males suggests possible direct mechanisms of sperm toxicity. In this study we aimed to correlate sperm function with semen levels of PAEs. Semen samples were obtained from 100 male patients attending the Unit of Andrology and Reproductive Medicine, University Hospital of Padova, (Italy), 22 of which having a recognized history of idiopathic infertility. Compared to fertile subjects, infertile patients showed reduced levels of acrosome reaction (AR), evaluated by CD46 staining upon progesterone (P4) triggering (p < 0.001). Subjects showing positive detection of PAEs in semen, evaluated by liquid chromatography-mass spectrometry (LC-MS), were significantly more represented in those reporting an history of infertility (13 out of 22), compared to fertile subjects (25 out of 78, P = 0.0266). In vitro sperm exposure to PAEs showed that lipophilic PAE representative Di-n-octyl phthalate (DNOP) had higher cell accumulation and inhibition of P4-induced AR than less lipophilic PAE representative Dibutyl phthalate (DBP). Computer-based binding analysis and fluorimetric inhibition assay, showed that both DNOP and DBP had similar Phospholipase-A2 (PLA2) inhibitory activity (respectively: 3.98 nM and 5.52 nM). However, only DNOP showed a significant inhibition of PLA2-mediated AR, triggered by A23187 calcium ionophore. Incubation with PLA2-related product arachidonic acid restored AR. Our data are suggestive of a novel mechanistic model of PAEs interference on sperm function, through the inhibition of PLA2-mediated signaling. According to this hypothesis, the inhibitory efficacy of the specific PAE is possibly linked to the corresponding cell accumulation

    A rapid decline of Apis mellifera, a keystone pollinator of wild plant species and agricultural crops, was recorded worldwide in recent years. The massive use of pesticides in agriculture associated with pollution generated by other human activities and presence of parasites, can cause toxicological effects in bees including a decrease of the immune defenses, leading to collapse of the colonies. In order to adequately monitor these pollinating organisms, it is necessary to develop and apply highly sensitive and integrated ecotoxicological investigation methods. The aim of this study was to develop and apply a set of ecotoxicological biomarkers to study the effects of environmental contaminants on bees. In a first phase we investigated in the laboratory the effects of EMS, cadmium and a commercial fungicide (Amistar®xtra) in adult honey bees, evaluating eventual variation in glutathione S-transferase (GST) and acetylcholinesterase (AChE) activities, erythrocyte nuclear abnormalities (ENA) assay and differential haemocytes count (DHC). Genotoxic effects as well alteration of the immune system were found in bees treated with EMS, cadmium or the fungicide. Cadmium and Amistar®xtra also inhibited AChE activity, GST was induced by the fungicide and by EMS. In a second phase adult honey bees were collected from apiaries located in four environments characterized by different chemical input: a wooded environment (low input), an urban site, an orchard and a cultivated countryside site. ENA assay showed that bees taken from the countryside and the orchard had a greater number of abnormalities compared to the forest, confirming the presence of genotoxic substances in agricultural environments compared to control environments. GST was induced in bees from the urban environment, AChE was found to be inhibited in the countryside compared to the forest, suggesting the presence of substances with neurotoxic effect in this environment

    Cutaneous Melanoma and Hormones: Focus on Sex Differences and the Testis

    Cutaneous melanoma, the most aggressive type of skin cancer, remains one the most represented forms of cancer in the United States and European countries, representing, in Australia, the primary cause of cancer-related deaths. Recently, many studies have shown that sex disparities previously observed in most cancers are particularly accentuated in melanoma, where male sex is consistently associated with an increased risk of disease progression and a higher mortality rate. The causes of these sex differences rely on biological mechanisms related to sex hormones, immune homeostasis and oxidative processes. The development of newer therapies, such as immune checkpoint inhibitors (ICIs) (i.e., anti–PD-1 and anti–CTLA-4 monoclonal antibodies) has dramatically changed the treatment landscape of metastatic melanoma patients, though ICIs can interfere with the immune response and lead to inflammatory immune-related adverse events (irAEs). Recently, some studies have shown a potential adverse influence of this immunotherapy treatment also on male fertility and testicular function. However, while many anticancer drugs are known to cause defects in spermatogenesis, the effects of ICIs therapy remain largely unknown. Notwithstanding the scarce and conflicting information available on this topic, the American Society of Clinical Oncology guidelines recommend sperm cryopreservation in males undergoing ICIs. As investigations regarding the long-term outcomes of anticancer immunotherapy on the male reproductive system are still in their infancy, this review aims to support and spur future research in order to understand a potential gonadotoxic effect of ICIs on testicular function, spermatogenesis and male fertility

    Human papillomavirus (HPV) infection is the most common sexually transmitted disease worldwide and is associated with negative reproductive outcomes because of which it is recommended to postpone medically assisted reproduction (MAR). This raises major concerns for elder infertile couples. We showed that a hyaluronidase-based sperm washing (IALu) procedure blunted the HPV viral load in semen. Here, were report two cases of couples with long-term idiopathic infertility, ascribed to persistent semen HPV detection, finding a beneficial outcome from the use of IALu protocol applied to intra-uterine insemination (IUI). Case 1: A Caucasian couple (female aged 32, male aged 35), complained of having been attempting pregnancy for 4 years. HPV-DNA (genotypes 51 and 54) was detected on sperms. After a first unsuccessful IUI cycle attempt, using standard swim-up selection of spermatozoa, a second IUI cycle using the IALu procedure was associated with a pregnancy and a successful trimester of gestation. Case 2: A Caucasian couple (female aged 43, male aged 52) complained of having been attempting pregnancy for 3 years and showed the detection of HPV-DNA (genotype 66) on sperms. After a first unsuccessful standard IUI cycle attempt, two further IUI cycles using IALu procedure were pursued. The last cycle was associated with a pregnancy and a successful trimester of gestation. Although preliminary, the IALu procedure is a promising approach for straightforward fertility treatments in cases of recurrent HPV-DNA semen detection, avoiding critical latencies
