Methods: Eleven fertility-related hashtags were chosen according to https://www.tagsfinder.

Quality of information provided by Brazilian Fertility Clinic websites: Compliance with Brazilian Medical Council (CFM) and American Society for Reproductive Medicine (ASRM) Guidelines.

COVID-19 and Renal Diseases: An Update.

Background: It becomes increasingly evident that the SARS-CoV-2 infection is not limited to the respiratory system. In addition to being a target of the virus, the kidney also seems to have a substantial influence on the outcomes of the disease.

Methods: Data was obtained by a comprehensive and non-systematic search in the PubMed, Cochrane, Scopus and SciELO databases, using mainly the terms "SARS-CoV-2", "COVID-19", "chronic kidney disease", "renal transplantation", acute kidney injury" and "renal dysfunction" Discussion: The membrane-bound angiotensin-converting enzyme 2 is the receptor for SARS-CoV- -2, and this interaction may lead to an imbalance of the Renin-Angiotensin System (RAS), associated with worse clinical presentations of COVID-19, including acute pulmonary injury, hyperinflammatory state and hematological alterations.
