Reverse transcriptase loop-mediated isothermal amplification (RT-LAMP) as a user-friendly system to detect SARS-CoV-2 infection: a multicentric study.

Although reverse transcriptase quantitative PCR remains the gold standard to perform viral detection, reverse transcriptase loop-mediated isothermal amplification (RT-LAMP) is already used to perform diagnosis of various infections. This work reports the results of a multicentric study performed in Sicily to evaluate the diagnostic power of an RT-LAMP kit for the diagnosis of SARS-CoV-2 infection on a total of 551 samples collected in January and February 2021, revealing sensitivity, specificity, accuracy, positive and negative predictive values ≥95%. Our results suggest the potential employment of this kit as a screening test to be used where fast and reliable results are demanded without the need for expensive instruments and highly-skilled personnel.

COVID-19 Vaccine and Death: Causality Algorithm According to the WHO Eligibility Diagnosis.

The current challenge worldwide is the administration of anti-severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccines. Even if rarely, severe vascular adverse reactions temporally related to vaccine administration have induced diffidence in the population at large. In particular, researchers worldwide are focusing on the so-called "thrombosis and thrombocytopenia after COVID-19 vaccination".

Rare spondylodiscitis due to .

Background: Nontuberculous mycobacteria (NTM) represents an important cause of infection, particularly in immunocompromised patients. Spondylodiscitis is unusual and may be associated with underlying causes such as drug abuse. Timely diagnosis and treatment are critical, as without this, patients will demonstrate progressive neurological deterioration.

Tuberculosis screening among healthcare workers in Sicily, Italy.

Tuberculosis (TB) is a diffuse communicable disease; and healthcare workers (HCWs) are among the at-risk populations for the disease. This study reports the result of TB surveillance in HCWs operating in three hospitals: one classified as 'low' risk for TB and two as 'medium' risk. A total of 2228 HCWs underwent TB screening using the standard Mantoux technique (also known as the tuberculin sensitivity test [TST]).

Vaccine-preventable disease in healthcare workers in Sicily (Italy): seroprevalence against measles.

Measles is one of the most infectious communicable diseases. The objective of this study was to determine the immunity to measles of healthcare workers (HCWs) operating in three hospitals of Catania. A total of 549 HCWs underwent measles screening.

Occupational exposure to fluoro-edenite and prevalence of anti-nuclear autoantibodies.

An environmental contamination due to an asbestiform mineral fiber, fluoro-edenite (FE), caused a significantly increased mortality rate for malignant mesothelioma in Biancavilla, Italy. Exposure to fluoro-edenite has been associated with inflammatory processes as an early response to inhaled fibers. The aim was to explore prevalence of anti-nuclear autoantibodies (ANA) in a group of construction workers residing and working in the contaminated area.

microRNAs and thyroid cancer: biological and clinical significance (Review).

Despite recent advances in the management of thyroid cancer, the survival rate of this tumor may still be improved. Therefore, the identification of biological and molecular features of indolent and aggressive disease would be critical to define clinically useful predictors of high-risk lesions. microRNAs (miRNAs) are small RNA molecules with regulatory function and marked tissue specificity that modulate multiple targets belonging to several pathways.
