The ethical plausibility of the ‘Right To Try’ laws

This is the author accepted manuscript. The final version is available from Elsevier via the DOI in this record.‘Right To Try’ (RTT) laws originated in the USA to allow terminally ill patients to request access to early stage experimental medical products directly from the producer, removing the oversight and approval of the Food and Drug Administration. These laws have received significant media attention and almost equally unanimous criticism by the bioethics, clinical and scientific communities. They touch indeed on complex issues such as the conflict between individual and public interest, and the public understanding of medical research and its regulation. The increased awareness around RTT laws means that healthcare providers directly involved in the management of patients with life-threatening conditions such as cancer, infective, or neurologic conditions will deal more frequently with patients’ requests of access to experimental medical products. This paper aims to assess the ethical plausibility of the RTT laws, and to suggest some possible ethical tools and considerations to address the main issues they touch.This paper was funded by the European School of Oncology

Effect of body mass and physical activity at younger age on the risk of prostatic enlargement and erectile dysfunction : Results from the 2018 #Controllati survey

Objective: Overweight and low physical activity (PA) increase the risk of prostatic enlargement and erectile dysfunction (ED). Less clear is the role of these factors at young age on the lifelong risk. Materials and methods: During June 2018 the Italian Society of Urologists organized the month of Male Urologic Prevention "#Controllati". Men aged 18 years or more were invited to attend urologic centers for a visit and counselling about urologic/andrologic conditions. Each participating man underwent a physical examination and was asked about urologic symptoms, sexual activity and possible related problems. Results: We analyzed data from 2786 men, aged 55.1 years (SD 10.9, range 19-97). A total of 710 (25.5%) subjects had a diagnosis of prostatic enlargement and 632 (22.7%) of DE. Overweight/obese men were at increased risk of prostatic enlargement and ED with corresponding odds ratio (0R) in comparison with normal or underweight men, being respectively 1.18 (95% Confidence Interval (CI) 1.00-1.44) and 1.69 (95% CI 1.39-2.05). The OR of prostatic enlargement in comparison with men reporting at age 25 a BMI < 25.0 was 1.22 (95% CI 1.01-1.51) for men with a BMI at 25 years of age 65 25; the corresponding OR value for ED was 1.17 (0.92- 1.48). Considering total PA at diagnosis, the OR of prostatic enlargement in comparison with no or low PA, was 0.69 (95%CI 0.55-0.86) for men reporting moderate PA and 0.75 (95%CI 0.58-0.98) for those reporting intense PA. When we considered PA at 25 years of age, the OR of subsequent diagnosis of prostatic enlargement, in comparison with men reporting no/low PA at 25 years of age was 0.81 (95%CI 0.63-1.04) for men reporting moderate PA and 0.70 (95%CI 0.52-0.99) for those reporting intense PA. Conclusions: These findings underline the utility of encouraging healthy lifestyle habits among young men in order to reduce the subsequent risk of prostatic enlargement and ED

Effect of 2 sex-sorting time schedules on SIT facility management

Improvements are needed in mosquito mass-rearing to effectively implement the sterile insect technique (SIT). However, managing this technique is challenging and resource intensive. SIT relies on mass rearing, sterilization, and release of adult males to reduce field populations. Maintaining an acceptable level of female presence, who can transmit viruses through biting, is crucial. Females are also essential for facility sustainability. Sex sorting plays a vital role in the production process, and our current mechanical sorting approach aims to obtain a high number of adult males with minimal female contamination within 24 h of pupation. Utilizing protandry helps control female contamination. While the 24-h sorting period achieves desired contamination levels, it may not yield enough females to sustain breeding lines, leading to increased labor costs that impact project sustainability. By delaying the sorting procedure to 48 h, we obtained sufficient females to sustain breeding lines, achieving a balance between male production and female contamination using the automatic version of the Fay-Morlan device as the sorting tool

Suitability of aquatic mosses for biomonitoring micro/meso plastics in freshwater ecosystems

Abstract Background Mesoplastics (5–25 mm) and microplastics (0.001–5 mm) are emerging pollutants of great concern. However, reliable methods of monitoring these types of plastic in river ecosystems have not yet been established. The goal of this work was to evaluate, for the first time, the suitability of Fontinalis antipyretica as a biomonitor of meso- and micro-plastics in rivers. With this aim, native samples of the moss and devitalized moss clones, held inside the bags, were compared for the uptake of fluorescent polystyrene particles under laboratory conditions, and for retention of plastic debris in the field, in sites close to wastewater treatment plants. Results In the laboratory experiment, the moss retained smaller microplastics, and a higher number of polystyrene meso and microplastics was counted in the moss bags than in the native moss. In the field study, the moss retained plastic debris chiefly in the form of fibres regardless of the capacity and flow rate of the wastewater treatment plants affecting each sampling site. The uniform morphology of moss clone seems to affect the retention of this type of pollutant. The FTIR analysis confirmed the particles entrapped by the moss bags as plastic, specifically polyethylene and polyamide type 6, among the most common plastic polymers detected in rivers. Conclusions The study findings highlighted the value of using uniform material, as the clone exhibited a greater accumulation efficiency with respect to the native moss. The mesh bags could act as selective filters and/or prevent the loss of adhering plastics. In the field, the bags favour plastic fibres retention despite the river flow. Finally, although FTIR is useful for the identification of plastic type, it is not very sensitive when small quantities of ground samples are used

Aedes albopictus Sterile Male Production: Influence of Strains, Larval Diet and Mechanical Sexing Tools

The sterile insect technique (SIT) is a biologically based method of pest control, which relies on the mass production, sterilization, and release of sterile males of the target species. Since females can transmit viruses, it is important to develop a mass rearing system to produce a large number of males with a low presence of females. We evaluated the effects of different strains, larval diets and sexing tools on male productivity and residual female presence for the application of SIT against Aedes albopictus. Strains coming from Italy, Germany, Greece, and Montenegro, with different levels of colonization, were reared with three larval diets: IAEA-BY, BLP-B and SLP-BY. Developed pupae were sexed using two different mechanical methods: sieve or Fay-Morlan separator. The results proved that adoption of the Fay-Morlan separator increased the productivity and limited the female presence. The IAEA-BY diet showed the lowest female contamination. Strains with a high number of breeding generations showed a decreased productivity and an increased female presence. Increased female presence was found only in extensively reared strains and only when the sorting operation was conducted with sieves. We hypothesize that extensive colonization may determine a size reduction which limits the sexing tool efficiency itself

Peyronie’s disease may negatively impact the sexual experience of a couple and female sexual function: A single center study

Background: Peyonie’s disease (PD) mostly affects males in the fifth decade of life, with a prevalence in the general population ranging between 0.5% and 20.3%. The pathology of PD is characterized by fibrosis of the tunic albuginea of the cavernous bodies of the penis, with the presence of pain in the erection and penile deformity. This is associated with decreased sexual function for both participants. The objective of the study was to investigate the influence of PD pathology on both male patients’ and their female partners’ sexual spheres, and analyze changes in sexual function and perception following penile correction surgery. Methods: Prospective study, we included male patients with PD and their female partner sexually active. Patients underwent corporoplasty with multiple plications. The male and female sexuality was evaluated before surgery and three months after male treatment by the Female sexual Function Index (FSFI); International Index of Erectile Function (IIEF); Visual Analogical Scale (VAS). Results: From January 2018 to November 2019 we included 35 couple. The female subjects before partner’s surgery presented dyspareunia, loss of sexual desire, inability to achieve orgasm, and sexual dissatisfaction. At three months after surgical treatment there was an improvement of sexual function in both male patients and female partners (desire P<0.0001, arousal P<0.0001, lubrification P<0.0001, orgasm P<0.0001, satisfaction P<0.0001, pain P<0.0001). As regarding male patients the pain decreased significantly (VAS score from 6 to 2.5), while there was no statistically significant improvement in erectile function (P=0.05). Conclusions: Our findings suggest that a viable approach to treatment of PD patients that involves their partners could lead to better functional and psychological results
