Reincidence Epidemiological Analysis for Positive Covid-19 Cases in Mexico

The pandemic caused by the SARS-CoV2 virus (COVID-19) represents an increase in the morbidity and mortality rate of the Mexican population, especially in people with health risk factors and associated medical history that despite already had COVID-19, present a second positive test and simultaneously a clinical relapse of the disease. OBJECTIVES: The epidemiological behavior of the pandemic requires creating challenges and implementing strategies for the prevention and mitigation of contagion risks in the occupationally productive population, prevention and mitigation of contagion is essential to avoid clinical cases of infection and reinfection of the disease in the working population. METHODOLOGY: Clinical and epidemiological follow-up of positive clinical cases of COVID-19 reinfection (period of more than 90 days) detected by monitoring PCR RT tests. RESULTS: From a total of (1626 patients) with a positive RT PCR laboratory result, the percentage of clinical relapse and a new positive laboratory test was 1.41% of the population in follow-up. Among the positive cases with a second laboratory test, 60.86% correspond to the male sex, an additional analysis is presented by age and time of reinfection. DISCUSSION: The analysis of this research finds an association of reinfection with patients with a history of smoking and bronchial asthma. Our study identifies reinfection by running two RT PCR tests separated by a period of more than 90 days from the initial infection resolution. CONCLUSIONS: The reinfection of COVID 19 occurred in employees after a first period of the disease is possible

Awareness of internet-based testing for sexually-transmitted and blood-borne infections among sexual minority men in British Columbia, Canada

BackgroundGetCheckedOnline is an internet-based testing program for HIV, Hepatitis C, and other sexually-transmitted infections (STIs) in British Columbia (BC), Canada. The program launched in 2014 in Vancouver, BC’s largest urban centre, and expanded to six smaller urban and suburban BC communities in 2016. We sought to measure GetCheckedOnline awareness among gay, bisexual, and other men who have sex with men (gbMSM), and to identify characteristics that may contribute to program awareness.MethodsSex Now was a cross-sectional online health survey of Canadian gbMSM aged ≥15 years recruited from 10/2019–02/2020. BC residents were asked if they knew about GetCheckedOnline and additional questions related to implementation outcomes. We built a multivariable logistic regression model including all variables significant in univariate analysis to quantify associations with awareness, and report adjusted odds ratios and 95% confidence intervals (AOR [95%CI]).ResultsAmong participants living in regions where GetCheckedOnline is available (n=1132, median age: 36 years), 38.1% were aware of GetCheckedOnline. Greater GetCheckedOnline awareness was associated with living outside of Vancouver (AOR=2.15 [1.50–3.10]), identifying as queer (AOR=1.58 [1.13–2.21]), having post-graduate education (AOR=1.84 [1.17–2.91]), being out to healthcare providers (AOR=1.97 [1.22–3.24]), using ≥3 geolocation-based sex-seeking apps (AOR=2.15 [1.40–3.33]), and past-year involvement in LGBTQ2S+-specific activities (AOR=1.56 [1.10–2.23]). Awareness decreased with increasing years of age (AOR=0.98 [0.97–1.00]). Compared with participants who usually tested for STIs at a sexual health clinic, awareness was lower among participants who usually tested for STIs through their family doctor (AOR=0.50 [0.33–0.73]) or at walk-in medical clinics (AOR=0.54 [0.30–0.96]), and among those who had never tested for STIs previously (AOR=0.17 [0.06–0.39]).ConclusionAlmost 40% of gbMSM in our sample were aware of GetCheckedOnline. Increasing promotion to gbMSM who are not out to their healthcare provider, who have never tested previously for STIs, or who are less connected to LGBTQ2S+ communities may improve program reach.

CT findings of pulmonary cysts.

Pulmonary cysts are thin-walled radiolucent lesions that may appear in a variety of uncommon disorders known as diffuse cystic lung diseases (DCLD) that essentially includes lymphangioleiomyomatosis (LAM), Langerhans cell histiocytosis (LCH), lymphocytic interstitial pneumonia (LIP), Pneumocystis jiroveci pneumonia (PJP), and Birt-Hogg-Dubé syndrome (BHDS). Moreover, they have been reported in several cases of coronavirus disease 2019 (COVID-19). The purpose of this review is to provide a practical approach for evaluating lung cysts when encountered on CT. We describe the imaging findings of DLCD emphasising their differences in terms of shape and distribution of the cysts, as well as their association with other findings such as nodules or ground-glass opacities, which may help in making a confident diagnosis. We also discuss the link between pulmonary cysts and COVID-19.
