Predictive Factors of Renal Failure in COVID-19 Patients at the Anti-COVID Center in lome, Togo

Background: Angiotensin-converting enzyme 2 has been identified as the receptor that allows the entry of SarsCov2 into the human cell. Its expression in the kidney is 100 times higher than in the lung;thus, making the kidney an excellent target for SarsCov2 infection manifesting as renal failure (RF). The objective of this study was to determine the predictive factors of RF during COVID-19 in the Togolese context. Patients and Methods: This was a retrospective descriptive and analytical study conducted at the lomé Anti-COVID Center including the records of patients hospitalized for COVID-19, of age ≥ 18 years and having performed a creatinemia. RF was defined by a GFR 2 calculated according to the MDRD formula. Patients were randomized into 2 groups according to GFRResults: 482 patients were selected for this study with a mean age of 58.02 years. Sixty-five percent of the patients were men, i.e., a sex ratio of 1.88. Fifty-two patients had RF, i.e., a frequency of 10.8%.There were 65% men (315 cases), for a sex ratio (M/F) of 1.88. Risk factors for renal failure in COVID-19 were age ≥ 65 years (ORa 2.42;CIa95% [1.17 - 4.95];p = 0.016), anemia (ORa 2.49;CIa95% [1.21 - 5.26];p = 0.015), moderate (ORa 13;CIa95% [2.30 - 2.44];p = 0.017), severe (ORa 26.2;CIa95% [4.85 - 4.93];p = 0.002) and critical (ORa 108;CIa95% [16.5 - 21.76];p Conclusion: Renal failure would therefore be related to the severity of COVID-19 and is the most formidable factor, conditioning the course of the disease and the patient’s vital prognosis.

long-term survival of participants in the prostate ：ancer prevention trial

The Prostate Cancer Prevention Trial （PCPT） is a seminal study in the field of urology. More than 10years after its initial publication, updated data from this trial continue to shape our understanding of prostate cancer. Among the major findings from the PCPT has been the demonstration that prostate cancer is common in men with prostate-specific antigen （PSA） once thought to be in the normal range,~ finasteride prevents the development of benign prostatic hypertrophy,2 it increases the sensitivity of PSA3 and digital rectal examination.4 Furthermore the PCPT helped to establish the link between erectile dysfunction and cardiovascular disease,5 and perhaps most importantly finasteride demonstrated a 25% relative risk reduction in the diagnosis of prostate cancer compared with placebo.

Recently the lHCb Collaboration [1] published the results of a search for the doubly charmed baryon ■. No significant signal is seen in the mass range from 3.4 to3.8 Ge V. To put this result in context, the ■baryon was seen by lHCb in decay modes ΛcK-π^+π^+[2](2017) and ■^+cπ^+[3](2018). The weighted average of the ■^++cc mass is 3621.24±0.65 (stat.)±0.31 (syst.)
