Non-COVID-19 respiratory viral infection.

Unlabelled: Implemented control measures brought about by the coronavirus disease 2019 (COVID-19) pandemic have changed the prevalence of other respiratory viruses, often relegating them to a secondary plan. However, it must not be forgotten that a diverse group of viruses, including other human coronaviruses, rhinoviruses, respiratory syncytial virus, human metapneumoviruses, parainfluenza and influenza, continue to be responsible for a large burden of disease. In fact, they are among the most common causes of acute upper and lower respiratory tract infections globally.

[Guidelines for the Treatment and Follow-Up of Patients with Q Fever].

Q fever (or query fever) is a zoonotic infectious disease with worldwide distribution transmitted by an intracellular Gram-negative bacterium, Coxiella burnetii. The most common identified sources of human infection are farm animals, such as sheep, goats and cattle. The disease is endemic in mainland Portugal, with most cases notified in the central and southern regions.

Multisystemic BCGitis: A rare complication of intravesical BCG immunotherapy for bladder cancer.

Intermediate- to high-grade non-muscle invasive bladder cancer is preferably treated with transurethral resection followed by adjuvant intravesical immunotherapy with Bacillus Calmette-Guérin (BCG). BCG acts as an immune stimulator, inducing a complex inflammatory response that selectively targets tumoral cells. Mild side effects of BCG instillation, such as fever, malaise, and bladder irritation are frequent, while severe treatment-associated complications of the genito-urinary tract are rare.

SARS-CoV-2 reinfection in a healthcare worker: First case in Portugal confirmed by viral genome sequencing.

Few reports of SARS-CoV-2 reinfection by antigenically similar variants are well documented. The interplay between natural acquired immunity, escape by emerging variants, and protective measures in the healthcare setting is considered in this description of the first phylogenetically confirmed SARS-CoV-2 reinfection in Portugal.

GSTM1 and GSTT1 genes null polymorphisms in kidney cancer susceptibility: evidence based on a meta-analysis.

Introduction: Renal cancer is a complex and multifactorial oncourologic disease.

Objective: To conduct a meta-analysis in order to investigate the association of GSTM1 and GSTT1 genes null polymorphisms in renal cancer.

Method: Case-control studies in humans, published from 1999 to 2013, that investigated the association of GSTM1 and GSTT1 genes null polymorphisms in renal cancer were grouped in order to make of this meta-analysis.
