Upgrading skin barrier Protection: Addition of active ingredients to a Gelatin/Tannic Acid-Based hydrogel patch for treating skin lesions related to Personal protective Equipment.

Prolonged use of Personal Protective Equipment, like surgical masks, can cause skin issues such as acne ("maskne") and rosacea flare-ups due to pressure and moisture. While dressings can protect the skin, they often reduce mask effectiveness and lack pharmaceuticals to treat common skin lesions. This study introduces an innovative dual-function gelatin/tannic acid-based hydrogel patch incorporating metronidazole (1% w/w) or salicylic acid (2% w/w) to offer both skin protection and treatment.

Characterization of SARS-CoV-2 nucleocapsid protein oligomers.

Oligomers of the SARS-CoV-2 nucleocapsid (N) protein are characterized by pronounced instability resulting in fast degradation. This property likely relates to two contrasting behaviors of the N protein: genome stabilization through a compact nucleocapsid during cell evasion and genome release by nucleocapsid disassembling during infection. In vivo, the N protein forms rounded complexes of high molecular mass from its interaction with the viral genome.

Regional Disparities in the Impact of Human Papillomavirus-Induced Lesions after 10 Years of HPV Vaccination Program in Brazil.

Background And Objective: Human papillomavirus (HPV) causes almost all cases of cervical cancer and its prevalence can be significantly reduced by vaccines. This study aimed to compare the prevalence of preneoplastic and neoplastic uterine cervix lesions in the cytology of Brazilian women aged 20-24 yr before and after the HPV vaccination campaign. The study also correlates these findings with the proportional coverage of first and second doses for this population.

Immune Response Against Influenza in a Cohort of Repeatedly Vaccinated Adults During the 2017/2018 and 2018/2019 Seasons.

Background/objectives: The influenza vaccination of healthcare workers (HCWs) is recommended each autumn and winter season by the relevant authorities in EU/EEA countries. The objective of this study was to evaluate the impact of repeated trivalent influenza vaccine (TIV) uptake during the 2017/2018 and 2018/2019 seasons on vaccine-derived immunity against influenza.

Methods: A cohort study of HCWs vaccinated with an annual TIV was conducted from October 2017 to June 2019.
