SARS-CoV-2 Reinfection among Healthcare Workers in Mexico: Case Report and Literature Review.

Since the onset of the COVID-19 pandemic, there have been multiple questions regarding reinfections associated with SARS-CoV-2. Healthcare workers on duty, due to overexposure in environments where there are more cases of COVID-19, are more prone to become infected by this virus. Here, we report 4 cases that meet the definition of clinical reinfection by SARS-CoV-2, as well as a literature review on this subject; all occurred in healthcare workers in Acapulco Guerrero, Mexico who provide their services in a hospital that cares for patients with COVID-19. The time between the manifestation of the first and second infection for each case was 134, 129, 107 and 82 days, all patients presented symptomatology in both events. The time between remission of the first infection and onset of second infection was 108, 109, 78 and 67 days for each case, while the time to confirmation by reverse transcription polymerase chain reaction (RT-PCR) between infections was 134, 124, 106 and 77 days. In two of the four cases the reinfection resulted in a more severe case, while in the remaining two cases the manifestation of symptoms and complications was similar to that presented in the first infection. Given this scenario, greater care is needed in the management of the pandemic caused by SARS-CoV-2 to protect healthcare workers and the general public from risks and complications caused by a possible reinfection by SARS-CoV-2.

Peer-Review and Rejection Causes in Submitting Original Medical Manuscripts.

The purpose of specialized medical journals is to accurately disseminate the results of new research. The peer-review process is crucial for journals to be able to fulfill this purpose. Although the peer-review determines whether scientific papers are accepted or rejected for publication, for many authors is a not well known process in its entirety. Many journals have focused on educating their audience about how and what is assessed during peer-review, nevertheless, the rate of manuscripts rejected because of easily-avoidable causes related to this, remains high. In this paper, we describe the process that specialized journals use to assess original medical manuscripts and list the main causes of paper rejection. Practicing physicians and medical students who wish to report their research results stand to benefit if they can identify and early avoid on the issues that most often arise during the peer-review process.
