Expansion of testing, isolation, quarantine, e-health and telemonitoring strategies in socioeconomically vulnerable neighbourhoods at primary healthcare in the fight against COVID-19 in Brazil: a study protocol of a multisite testing intervention using a mixed method approach.

Introduction: The key tools for mitigating the impact of COVID-19 and reducing its transmission include testing, quarantine and isolation, as well as telemonitoring. Primary healthcare (PHC) can be essential in increasing access to these tools. Therefore, the primary objective of this study is to implement and expand an intervention consisting of COVID-19 testing, isolation, quarantine and telemonitoring (TQT) strategies and other prevention measures at PHC services in highly socioeconomically vulnerable neighbourhoods of Brazil.

Repurposing Tamoxifen as Potential Host-Directed Therapeutic for Tuberculosis.

The global burden of tuberculosis (TB) is aggravated by the continuously increasing emergence of drug resistance, highlighting the need for innovative therapeutic options. The concept of host-directed therapy (HDT) as adjunctive to classical antibacterial therapy with antibiotics represents a novel and promising approach for treating TB. Here, we have focused on repurposing the clinically used anticancer drug tamoxifen, which was identified as a molecule with strong host-directed activity against intracellular Mycobacterium tuberculosis ().

What's New in Allergen Immunotherapy Patents? A Review.

In recent years, allergies are on the rise. The growth of allergies cases has changed the immune system's response to new pathogens. The therapy used to treat these diseases is based on allergen avoidance, pharmacotherapy and allergen-specific immunotherapy.

Challenges and proposals for scaling up COVID-19 testing and diagnosis in Brazil.

The Brazilian context of social inequalities and barriers in accessing health services may deteriorate the situation of the COVID-19 pandemic, which already affects all Brazilian federative states, with the growing curve of increasing confirmed cases and deaths. National governments and scientific field agents have been looking for evidence for the best practices of prevention and control of transmission, and care of infection and disease, including diagnosis, treatment, and health care measures. The large-scale testing strategy, aimed at early diagnosis, quarantine of the mild cases identified, as well as those of the contacts, and adequate care of severe cases, has been revised and indicated as one of the efficient pandemic control measures in several countries in the world.
