    Kurzfassung: The first direct gravitational‐wave detection was made by the Advanced Laser Interferometer Gravitational Wave Observatory on September 14, 2015. The GW150914 signal was strong enough to be apparent, without using any waveform model, in the filtered detector strain data. Here, features of the signal visible in the data are analyzed using concepts from Newtonian physics and general relativity, accessible to anyone with a general physics background. The simple analysis presented here is consistent with the fully general‐relativistic analyses published elsewhere, in showing that the signal was produced by the inspiral and subsequent merger of two black holes. The black holes were each of approximately , still orbited each other as close as ∼350 km apart and subsequently merged to form a single black hole. Similar reasoning, directly from the data, is used to roughly estimate how far these black holes were from the Earth, and the energy that they radiated in gravitational waves.

    Kurzfassung: People who inject drugs (PWID) constitute the largest reservoir of hepatitis C virus (HCV). Although effective medications are available and access to care is universal in Italy, the proportion of PWID receiving appropriate care remains low. Design and Methods To identify the major barriers for PWID to HCV treatment we surveyed a large sample of practitioners working in outpatient addiction centres (SerDs). The survey was conducted in two stages and involved 30.3% of SerDs operating in Italy. In the first, SerD physicians completed a questionnaire designed with a Delphi structure. In the second, SerD practitioners completed a targeted questionnaire to identify barriers to four SerD services in HCV management: screening, referral, treatment and harm reduction. Results The first‐stage questionnaire, in which a Delphi and RAND‐UCLA method was used, revealed a lack of agreement among the physicians about barriers to health care. The more detailed second‐stage questionnaire indicated the barriers to delivering specific SerD services. As regarded the delivery of all four services, the major reasons for treating 〈 50% of patients were: physician and nurse understaffing, technical, economic and logistic issues. In contrast, the practitioners who responded that they follow protocol recommendations often deliver all four services to 〉 50% of patients. Discussion and Conclusions HCV treatment remains out of reach for many PWID attending a drug treatment centre in Italy. To meet the World Health Organisation (WHO) target, there is a need to increase economic, technical and staff support at treatment centres using the protocols and the universal health care already in place.

    Kurzfassung: Risk factors established during adolescence affect health outcomes in adulthood, although little is known about how adolescent health risk behaviours ( HRB s) affect testicular development and reproductive health. Objectives To assess prevalence of HRB s among last year high school students; to describe the most prevalent andrological disorders in this cohort; to explore HRB s associated with andrological disorders and investigate factors possibly associated with impaired testicular development in puberty. Materials and methods The Amico‐Andrologo Survey is a permanent nationwide surveillance programme conducted by the Italian Society of Andrology and Sexual Medicine and supported by the Ministry of Health. A nationally representative survey of final‐year male high school students was conducted using a validated structured interview ( n  = 10124) and medical examination ( n  = 3816). Results Smoking (32.6%), drinking (80.6%) and use of illegal drugs (46.5%) are common in adolescence. 16.6% of subjects were overweight, 3.1% were underweight and 2.3% were obese. Among sexually active students (60.3%), unprotected sex was very common (48.3%). Only 11.6% had been treated for andrological disorders, despite an abnormal clinical examination in 34.6%. Bilateral testicular hypotrophy (14.0%), varicocoele (27.1%) and phimosis (7.1%) were the most prevalent disorders; 5.1% complained of premature ejaculation and 4.7% had an STI . Underweight and heavy alcohol or drug use were associated with testicular hypotrophy. HRB s emerged as significant predictors of testicular hypotrophy, explaining up to 9.6% of its variance. Limitations include risk of selection bias for voluntary physical examination and recall bias for the self‐compiled questionnaire. Discussion There is an emerging global adverse trend of HRB s in male high school students. A significant proportion of adolescent males with unsuspected andrological disorders engage in behaviours that could impair testicular development. Conclusion Greater attention to the prevention of andrological health in adolescence is needed.
