HTE-Enabled Development of an Ene-Reductase-Catalyzed Desymmetrization: Remote Control of All-Carbon Quaternary γ-Centers.

We report the remote stereocontrol of all-carbon quaternary γ-centers via an ene-reductase (ERED)-catalyzed desymmetrization of prochiral cyclohexadienones. By leveraging high-throughput experimentation (HTE) protocols, we were able to rapidly identify EREDs capable of desymmetrizing both spirocyclic cyclohexadienones and non-spirocyclic 2,6-disubstituted cyclohexadienone substrates in up to 85% yield with excellent levels of stereoselectivity (up to >99% ee and >20:1 dr) under mild reaction conditions.

Minimally invasive type A aortic dissection repair: aortic valve resuspension with neomedia creation and the Ascyrus Medical Dissection Stent.

Type A aortic dissection is a life-threatening condition that requires immediate surgical intervention. The goal of traditional approaches is to treat the disease promptly, regardless of invasiveness, in order to achieve the quickest surgical outcome. This strategy has been shown to be associated with significant morbidity, extended recovery and postoperative complications.

Sex differences in response to COVID-19 mRNA vaccines in Italian population.

Since the beginning of mass vaccination campaign for COVID-19 in Italy (December 2020) and following the rapidly increasing vaccine administration, sex differences have been emphasized. Nevertheless, incomplete and frequently incoherent sex-disaggregated data for COVID-19 vaccinations are currently available, and vaccines clinical studies generally do not include sex-specific analyses for safety and efficacy. We looked at sex variations in the COVID-19 vaccine's effectiveness against infection and severe disease outcomes.

Case-time series study on the short-term impact of meteorological factors on West Nile Virus incidence in Italy at the local administrative unit level, 2012 to 2021.

Introduction: West Nile Virus (WNV) is a significant public health concern in southern Europe, with meteorological, climatic, and environmental factors playing a critical role in its transmission dynamics. This study aims to assess the short-term effects of meteorological variables on the incidence of WNV in five Italian regions in Northern Italy from 2012 to 2021.

Methods: Linking epidemiological data from the national surveillance system and local meteorological data, we conducted a Case-Time Series analysis to examine the association between WNV incident cases and temperature, humidity, and precipitation recorded up to ten weeks before case occurrence at the local administrative unit level.

Impact of the 2023/24 autumn-winter COVID-19 seasonal booster campaign in preventing severe COVID-19 cases in Italy (October 2023-March 2024).

We assessed the impact of the 2023/2024 COVID-19 vaccination campaign in Italy by estimating the number of averted COVID-19 severe cases (i.e. COVID-19 associated hospitalisations or deaths) between October 2023 and March 2024, in those aged ≥60 years.
