Low Serum Albumin Predicts Severe Outcomes in COVID-19 Infection: A Single-Center Retrospective Case-Control Study.

Background: Coronavirus disease 2019 (COVID-19) can cause serious complications such as multiorgan failure and death which are difficult to predict. We conducted this retrospective case-control observational study with the hypothesis that low serum albumin at presentation can predict serious outcomes in COVID-19 infection.

Methods: We included severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) reverse transcriptase-polymerase chain reaction (RT-PCR) confirmed, hospitalized patients from March to July 2020 in a tertiary care hospital in the USA.

Low serum albumin and the risk of hospitalization in COVID-19 infection: A retrospective case-control study.

Background: The data on the COVID-19 patients who were discharged to self-quarantine is lacking.

Aim: The aim of the study was to investigate the percentage of COVID-19 positive patients that were hospitalized within a three-week period after discharge from ED to self-quarantine.

Methods: The patients who had confirmed SARS-CoV-2 on RT-PCR of the nasopharyngeal swab and were discharged from ED of a tertiary care hospital in the USA to self-quarantine from March 01- July 31, 2020, were included.

A Retrospective Analysis of Hospital Electrocardiogram Auto-Populated QT Interval Calculation.

Background The current electrocardiogram (ECG) standard for rate correction of the QT interval (QTc) is a power function known as the Bazett formula (QTcB). QTc formulae are either power functions or linear functions. QTcB is known to lack reliability, as heart rate (HR) rises from or falls below 60 beats per minute (bpm).

Cannabinoid-Induced Brugada Syndrome: A Case Report.

Brugada syndrome, also called Pokkuri Death Syndrome, is an autosomal dominant electrophysiological phenomenon that increases the risk of spontaneous ventricular tachyarrhythmia and sudden cardiac death. Due to sodium channel mutations in the cardiac membrane, most commonly SCN5A and SCN10A, the heart can be triggered into a fatal arrhythmia. Brugada syndrome can be triggered by fever, and medications including antiarrhythmics, psychotropics, and recreational drugs like cocaine and marijuana.
