ABSTRACT
INTRODUCTION: The associations among SARS-CoV-2 infection, vaccination and total serum prostate serum antigen (PSA) levels in men undergoing screening for prostate cancer are unknown. METHODS: A retrospective analysis of data from a large health maintenance organization. Records of individuals aged 50 to 75 years with two serum PSA tests taken between March 2018 and November 2021 were included. Individuals with prostate cancer were excluded. Changes in PSA levels were compared between individuals who had at least 1 SARS-CoV-2 vaccination and/or infection between the two PSA tests and individuals who did not have an infection and were not vaccinated between the two PSA tests. Subgroup analyses were performed to assess the impact of the elapsed time between the event and the second PSA test on the results. RESULTS: The study and control groups included 6,733 (29%) and 16 286 (71%) individuals, respectively. Although the median time between PSA tests was shorter in the study vs. the control group (440 vs. 469 days, P<.001), PSA elevation between the tests was higher in the study group (0.04 vs. 0.02, P<.001). The relative risk for PSA elevation ≥1 ng/dL was 1.22 (95% CI 1.1, 1.35). Among individuals who were vaccinated, PSA increased by 0.03 ng/dL (IQR -0.12, 0.28) and 0.09 ng/dL (IQR -0.05, 0.34) after 1 and 3 doses, respectively (P<.001). Multivariate linear regression showed that SARS-CoV-2 events (ß 0.043; 95% CI 0.026-0.06) were associated with a greater risk for PSA elevation, after adjusting for age, baseline PSA and days between PSA tests. CONCLUSION: SARS-CoV-2 infection and vaccinations are associated with a slight increase in PSA, with the third anti-COVID vaccine dose having a more prominent impact, but its clinical significance is unknown yet. Any significant increase in PSA must be investigated and cannot be dismissed as secondary to SARS-CoV-2 infection or vaccination.
ABSTRACT
Initial deleterious effects of the COVID-19 pandemic on urologic oncology surgeries are well described, but the possible influence of vaccination efforts and those of pandemic conditions on surgical volumes is unclear. Our aim was to examine the association between changing vaccination status and COVID-19 burden throughout the pandemic and the volume of urologic oncology surgeries in Israel. This multi-center cross-sectional study included data collected from five tertiary centers between January 2019 and December 2021. All 7327 urologic oncology surgeries were included. Epidemiological data were obtained from the Israeli Ministry of Health database. A rising trend in total urologic oncology surgery volumes was observed with ensuing COVID-19 wave peaks over time (X2 = 13.184, df = 3, p = 0.004). Total monthly surgical volumes correlated with total monthly hospitalizations due to COVID-19 (R = -0.36, p = 0.015), as well as with the monthly average Oxford Stringency Index (R = -0.31, p = 0.035). The cumulative percent of vaccinations and of new COVID-19 cases per month did not correlate with total monthly urologic surgery volumes. Our study demonstrates the gradual acclimation of the Israeli healthcare system to the COVID-19 pandemic. However, hospitalizations due to COVID-19, as well as restriction stringency, correlate with lower volumes of urologic oncological surgeries, regardless of the population's vaccination status.
ABSTRACT
PURPOSE: To evaluate trends in emergency room (ER) urological conditions during COVID-19 pandemic lockdown. MATERIALS AND METHODS: Retrospective analyses of renal colic, hematuria, and urinary retention in ER's admissions of a tertiary hospital during the lockdown period (March 19 to May 4, 2020) in Israel. Patient's demographics and clinical characteristics were compared to those in corresponding periods during 2017-2019, with estimated changes in ER arrival and waiting times, utilization of imaging tests, numbers of hospitalizations, and urgent procedure rates. RESULTS: The number of ER visits for renal colic, hematuria, and urinary retention decreased by 37%, from an average of 451 (2017-2019) to 261 patients (2020). Clinical severity was similar between groups, with no major differences in patient's age, vital signs, or laboratory results. The proportion of ER visits during night hours increased significantly during lockdown (44.8% vs. 34.2%, p=0.002). There was a decrease in renal colic admission rate from 19.8% to 8.4% (p=0.001) without differences in urgent procedures rates, while the 30-day revisit rate decreased from 15.8% to 10.3% during lockdown (p=0.02). CONCLUSIONS: General lockdown was accompanied by a significant decrease in common urological presentations to the ER. This change occurred across the clinical severity spectrum of renal colic, hematuria, and urinary retention. In the short term, it appears that patients who sought treatment did not suffer from complications that could be attributed to late arrival or delay in treatment. The long-term implications of abstinence from seeking emergent care are not known and require further investigation.
