SARS-CoV-2 mRNA Vaccine Breakthrough Infections in Fully Vaccinated Healthcare Personnel: A Systematic Review.

The number of people vaccinated against COVID-19 increases worldwide every day; however, it is important to study the risk of breakthrough infections in vaccinated individuals at high risk of exposure such as healthcare personnel (HCP). A systematic literature review (SLR) applying the PRISMA declaration and the PECOS format using the following entry terms was used: "Health Personnel OR Healthcare Worker OR Healthcare Provider OR Healthcare Personnel AND breakthrough OR infection after vaccine*". The research was carried out utilizing the following databases: SCOPUS, PubMed, Embase, and Web of Sciences.

Rare gastrointestinal lymphomas: The endoscopic investigation.

Gastrointestinal lymphomas represent up to 10% of gastrointestinal malignancies and about one third of non-Hodgkin lymphomas. The most prominent histologies are mucosa-associated lymphoid tissue lymphoma and diffuse large B-cell lymphoma. However, the gastrointestinal tract can be the site of rarer lymphoma subtypes as a primary or secondary localization.

Salvage therapy with pegylated liposomal doxorubicin, bortezomib, cyclophosphamide, and dexamethasone in relapsed/refractory myeloma patients.

Objectives: In vitro studies have shown synergistic anti-myeloma effects of bortezomib combined with alkylating agents or anthracycline. We tested safety and efficacy of the combination of bortezomib, doxorubicin cyclophosphamide, and dexamethasone (ABCD) in the treatment of relapsed/refractory myeloma.

Methods: ABCD consisted of bortezomib given intravenous (IV) at dosage 1.

Long-term persistence of seroprotection by hepatitis B vaccination in healthcare workers of southern Italy.

Background: The impact of hepatitis B virus (HBV) vaccination campaigns on HBV epidemiology needs to be evaluated, in order to assess the long-term immunity offered by vaccines against HBV.

Objectives: To evaluate the current status of anti-HBV vaccine coverage among healthcare workers (HCWs) in Southern Italy, and to determine the long-term persistence of antibodies to hepatitis B surface antigens (anti-HBs) in such a cohort of subjects.

Patients And Methods: A longitudinal, retrospective seroepidemiological survey was conducted among 451 HCWs, who were working at or visiting, the Occupational Health Department of a city hospital, in Catania, Italy, between January 1976 and December 2010.

Genomic analysis: toward a new approach in breast cancer management.

Breast cancer is a clinically heterogeneous and complex disease that can affect differently individuals with seemingly identical clinicopathologic parameters. This heterogeneity is strictly linked to individuals and tumors genetic variability. Currently, the development of high-throughput technologies are proving novel tools to tackle this complexity.
