Laboratory findings in SARS-CoV-2 infections: State of the art.
The scientific community is constantly assessing the clinical and laboratory manifestations of COVID-19 in the organism. In view of the fragmentation of the large amount of information, knowledge gaps in relation to laboratory markers, and scarcity of papers in Portuguese, we propose a Literature review on laboratory changes observed in patients infected with SARS-CoV-2. ⋯ There is a need for further studies on the new SARS-CoV-2. So far, there is no consensus regarding laboratory findings and their usefulness, whether as a prognostic marker, mortality, or disease severity.

Hormone therapy after risk-reducing surgery in patients with BRCA1/BRCA2 mutation: evaluation of potential benefits and safety.
Women with mutations in the BRCA 1 and 2 genes are at increased risk for ovarian and breast cancer and therefore candidates for risk-reducing surgery, including salpingo-oophorectomy and mastectomy. Risk-reducing salpingo-oophorectomy (RRSO) is considered the most effective prophylactic measure for ovarian cancer prevention in this group of patients. ⋯ However, the potential hormonal stimulation of these tumors and the risk of breast cancer are a concern regarding the safety of hormone replacement therapy (HRT) in this population. This article aims to review the current evidence regarding the potential benefits and safety of HRT after RRSO.

Relationship between c-reactive protein/albumin ratio and new-onset atrial fibrillation after coronary artery bypass grafting.
This study aimed to investigate the predictive value of the newly defined C-Reactive Protein (CRP)/Albumin Ratio (CAR) in determining the development of atrial fibrillation (AF) in comparison with other inflammatory markers, such as Neutrophil/Lymphocyte (N/L) Ratio and Platelet/Lymphocyte (P/L) Ratio, in patients undergoing Coronary Artery Bypass Grafting (CABG) surgery. ⋯ Novel inflammatory marker CAR can be used as a reliable marker to predict the development of AF following CABG.

Comparative StudyComparison of tru-cut biopsy and fine-needle aspiration cytology in an experimental alcoholic liver disease model.
Liver biopsies such as tru-cut (sharp needle) and fine-needle aspiration cytology (FNAC) are the most commonly preferred techniques to detect the grade and stage of certain liver diseases. In this study, we aimed to compare the efficiency of USG-guided tru-cut biopsy and fine-needle aspiration cytology in an experimental alcoholic liver disease model. ⋯ Both techniques were superior in some aspects. FNAC can be an attractive alternative to tru-cutbiopsy and applied in routine practice in the diagnosis of non-tumoral liver diseases.
