Assessment of SARS-CoV-2 RNA shedding in semen of 36 males with symptomatic, asymptomatic, and convalescent infection during the first and second wave of COVID-19 pandemic in Italy.

The severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) receptor, angiotensin-converting enzyme 2 (ACE2), has been identified in the human testis, but the risk of transmission of SARS-CoV-2 through sexual intercourse still needs to be defined. The goal of our study was to determine if SARS-CoV-2 is detectable in the semen of patients suffering or recovering from coronavirus disease-19 (COVID-19), still testing positive at nasopharyngeal swabs but showing mild or no symptoms at the time of sampling. Detection of SARS-CoV-2 RNA in semen was performed by real-time reverse transcriptase-polymerase chain reaction (RT-PCR) and nested PCR targeting open reading frame (ORF) 1ab.

Recombinant GII.P16 genotype challenges RT-PCR-based typing in region A of norovirus genome.

Objectives: In latest years GII.4[P16] and GII.2[P16] noroviruses have become predominant in some temporal/geographical settings.

Automatic detection and measurement of nuchal translucency.

In this paper we propose a new methodology to support the physician both to identify automatically the nuchal region and to obtain a correct thickness measurement of the nuchal translucency. The thickness of the nuchal translucency is one of the main markers for screening of chromosomal defects such as trisomy 13, 18 and 21. Its measurement is performed during ultrasound scanning in the first trimester of pregnancy.

[Transient left ventricular apical ballooning with dynamic outflow tract obstruction complicated by persistent hypotension].

The pathogenesis of tako-tsubo syndrome remains, nowadays, unclear: it is likely that the relevance of the different proposed mechanisms differs among specific clinical contexts. In this paper, we describe the case of a 61-year-old woman admitted to the intensive cardiac care unit for pre-syncope and persistent hypotension. Clinical and echocardiographic data were suggestive of tako-tsubo syndrome with severe dynamic left ventricular outflow tract (LVOT) obstruction and severe mitral regurgitation.
