Cycle threshold predicted mortality in a cohort of patients with hematologic malignancies infected with SARS-CoV-2.

When a SARS-CoV-2 RT-qPCR test is performed, it may determine an indirect measure of viral load called cycle threshold (Ct). Respiratory samples with Ct <25.0 cycles are considered to contain a high viral load.

Descriptive analysis of Cycle Threshold in patients with hematologic malignancies infected with SARS-COV-2.

Introduction: SARS-CoV-2 has caused over 200 million documented infections, more than 4 million deaths, and unprecedented consequences worldwide. The cycle threshold (Ct), the number of amplification cycles required to obtain a product detectable through fluorescence during a quantitative RT-PCR test, is an indirect measurement of viral load. Patients with hematologic malignancies have an increased risk of death by the SARS-CoV-2.

Screening for SARS-COV-2 Using RT-qPCR in Patients with Hematologic Neoplasms Receiving Chemotherapy.

It has been recommended that patients with leukaemias and lymphomas undergo universal screening for SARS-COV-2 using RT-qPCR before each treatment on the grounds of their high risk of experiencing severe forms of COVID-19. This raises a conflict with different recommendations which prioritise testing symptomatic patients. We found that among 56 RT-qPCR obtained in asymptomatic patients with hematologic neoplasms before chemotherapy administration, 2 (3.

[The medical curriculum, students and teachers. Which should be their role?].

A century after the Flexner report in 1910, the book entitled "Educating Physicians: A Call for Reform of Medical School and Residency" was published, which called for strengthening the formation of professional identity, integrating basic sciences with clinical learning and implementing competency assessment. Traditional education is not compatible with these recommendations. One learns to do by doing it, and the way to achieve this is to “play the whole game”.
