A case of chronic kidney disease patient with rapid deterioration of renal function, hair loss, and spontaneous resolution of facial warts after COVID-19 infection. Aging Med (Milton) 2024; 7:131-135. [PMID: 38571671 PMCID: PMC10985768 DOI: 10.1002/agm2.12281] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/06/2023] [Revised: 12/11/2023] [Accepted: 12/19/2023] [Indexed: 04/05/2024] Open
Abstract
Background Individuals with pre-existing chronic kidney disease (CKD) are at an increased risk of experiencing severe symptoms if infected with COVID-19. This report presents the case of a patient with CKD who contracted COVID-19 and subsequently experienced rapid deterioration of kidney function, hair loss, and spontaneous remission of facial warts. Case presentation A 60-year-old Chinese man with a decade-long history of abnormal serum creatinine (Scr) levels and recently heightened fatigue sought treatment. The disease was previously managed and deemed resolved in 2020. However, when he contracted the novel coronavirus on December 20, 2022, he experienced persistent fatigue without other symptoms. In early January 2023, Scr levels was examined as more than 300 μmol/L. This was followed by hair loss, including eyebrows and lashes, and the spontaneous resolution of a longstanding facial wart. During this period, although the patient received kidney-protecting drugs and a lifestyle optimization, Scr increased continuously and the disease eventually progressed to the uremic stage. As the patient still had relatively abundant urine volume, the patient chose peritoneal dialysis treatment. At a two-month follow-up, he had adhered to the CAPD protocol without complications and his hair had begun to regrow. After eight months, his hair had mostly regrown, and his Scr levels kept stable. Conclusion This case may represent the inaugural instance of CKD patients experiencing rapid deterioration of renal function, hair loss, and spontaneous remission of common warts. The underlying mechanisms of this unique phenomenon warrant further researches and debate.

Prolonged impacts of COVID-19-associated cystitis: A study on long-term consequences. World J Clin Cases 2023; 11:7987-7993. [DOI: 10.12998/wjcc.v11.i33.7987] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/28/2023] [Revised: 11/06/2023] [Accepted: 11/17/2023] [Indexed: 11/24/2023] Open
Abstract
BACKGROUND The Coronavirus Disease 2019 (COVID-19) caused by the severe acute respiratory syndrome coronavirus 2 virus is an international health concern with substantial morbidity and mortality. COVID-associated cystitis (CAC), presents as new onset or exacerbated urinary symptoms, resembling overactive bladder (OAB) symptoms.
AIM To examines the long-term outcomes of patients with CAC in the context of Long COVID.
METHODS A cohort of 350 patients admitted to Detroit Hospitals with COVID-19 between May and December 2020, displaying CAC symptoms following discharge, was prospectively followed. Initial urologic evaluations occurred at 10-14 wk and were repeated at 21-28 mo post-discharge. Symptoms were managed conservatively, employing behavioral modifications and standard OAB medications. Participants completed surveys assessing urinary symptoms and quality of life (QoL) at both time points. The primary outcome was the Urology Care Foundation Overactive Bladder Assessment Tool.
RESULTS 87% of the final cohort (n = 310) reported symptom improvement at 21-28 mo post-discharge. Patients with new onset CAC symptoms showed a median decrease of 9-10 points in OAB and QoL scores, while those with existing symptoms experienced a decrease of 6 points. Overall, 95.4% of patients with new onset symptoms reported symptom improvement at follow-up, contrasting with 60.7% among those with existing symptoms.
CONCLUSION This study presents the first long-term follow-up of adult patients with CAC, revealing a promising prognosis with conservative management measures in the context of Long COVID. These findings provide reassurance to patients regarding symptom resolution and underscore the need for further research into this evolving aspect of COVID-19's impact on urological health.

Our Experience with SARS-CoV-2 Infection and Acute Kidney Injury: Results from a Single-Center Retrospective Observational Study. Healthcare (Basel) 2023; 11:2402. [PMID: 37685436 PMCID: PMC10487568 DOI: 10.3390/healthcare11172402] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/17/2023] [Revised: 08/09/2023] [Accepted: 08/15/2023] [Indexed: 09/10/2023] Open
Abstract
BACKGROUND Renal failure in COVID-19 patients is reportedly related to multiple factors such as a direct SARS-CoV-2 cytopathic effect, cytokine storm, the association of pulmonary and/or cardiovascular lesions, the presence of thrombotic microangiopathy, endothelial damage, or the use of potentially nephrotoxic medications. METHODS We retrospectively analyzed 466 cases of SARS-CoV-2 infection, comparing 233 patients with acute kidney injury (AKI) with 233 patients without AKI in terms of their demographic characteristics, comorbidities, clinical background, laboratory investigations, time of AKI onset, therapy, and outcomes after using univariate analysis and a CART decision-tree approach. The latter was constructed in a reverse manner, starting from the top with the root and branching out until the splitting ceased, interconnecting all the predictors to predict the overall outcome (AKI vs. non-AKI). RESULTS There was a statistically significant difference between the clinical form distribution in the two groups, with fewer mild (2 vs. 5) and moderate (54 vs. 133) cases in the AKI group than in the non-AKI group and more severe and critical patients in the AKI cohort (116 vs. 92 and 60 vs. 3). There were four deaths (1.71%) in the non-AKI group and 120 deaths in the AKI group (51.5%) (p-value < 0.001). We noted statistically significant differences between the two study groups in relation to different tissue lesions (LDH), particularly at the pulmonary (CT severity score), hepatic (AST, ALT), and muscular levels (Creatine kinase). In addition, an exacerbated procoagulant and inflammatory profile in the study group was observed. The CART algorithm approach yielded decision paths that helped sort the risk of AKI progression into three categories: the low-risk category (0-40%), the medium-risk category (40-80%), and the high-risk category (>80%). It recognized specific inflammatory and renal biomarker profiles with particular cut-off points for procalcitonin, ferritin, LDH, creatinine, initial urea, and creatinine levels as important predictive factors of AKI outcomes (93.3% overall performance). CONCLUSIONS Our study revealed the association between particular risk factors and AKI progression in COVID-19 patients. Diabetes, dyspnea on admission, the need for supplemental oxygen, and admission to the intensive care unit all had a crucial role in producing unfavorable outcomes, with a death rate of more than 50%. Necessary imaging studies (CT scan severity score) and changes in specific biomarker levels (ferritin and C-reactive protein levels) were also noted. These factors should be further investigated in conjunction with the pathophysiological mechanisms of AKI progression in COVID-19 patients.

Cohort study of hospitalized patients with COVID-19 at Brazilian tertiary-care hospital: Occurrence of adverse events and mortality. Braz J Infect Dis 2023; 27:102791. [PMID: 37500062 PMCID: PMC10407272 DOI: 10.1016/j.bjid.2023.102791] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/06/2023] [Revised: 06/02/2023] [Accepted: 07/04/2023] [Indexed: 07/29/2023] Open
Abstract
INTRODUCTION Patients hospitalized with COVID-19 are often submitted to invasive procedures and they are at risk for hospital-associated adverse events. OBJECTIVES To evaluate the epidemiological and clinical aspects of patients hospitalized with COVID-19; the occurrence of adverse events and the risk factors for mortality. METHOD Cohort study that included adult patients hospitalized with a diagnosis of SARSCoV-2 infection, at the tertiary University Hospital of UNICAMP from March 2020 to March 2021. Patients were identified through the hospital epidemiological surveillance system and followed until discharge or death. Descriptive, comparative, and logistic regression analysis was performed. RESULTS 650 adult patients were included. The main adverse events identified were nosocomial infections (31.5%), renal failure (33.8%), thromboembolic and vascular events (12.6%). Mortality was higher among those with bloodstream infections (30.2% vs. 8.6%; p < 0.0001), ventilator-associated pneumonia (VAP, 52.5% vs. 12.3%; p < 0.0001), catheter associated urinary infection (27.3% vs. 7.2%; p < 0.0001); thromboembolic and vascular events (23.0% vs. 9.9%; p < 0.0001) and renal failure (81.3% vs. 20.9%; p < 0.0001). Klebsiella pneumoniae (15.6%), Pseudomonas aeruginosa (14.4%), Enterococcus faecalis (8.6%) were the most isolated bacteria. Logistic regression analysis identified age, (RR = 1.03; 95% CI 1.02 to 1.05); ICU admission (RR = 3.06; 95% CI 1.59 to 5.87), vasoactive drug use (RR = 3.1; 95% CI 1.79 to 4.82); renal failure (RR = 7.76; 95% CI 4.54 to 13.26); and VAP (RR = 2.2; 95% CI 1.23 to 3.96), independently associated with mortality. CONCLUSION adverse events have an important impact on the evolution of patients with COVID-19, reinforcing the need for optimized prevention and control measures as an essential part of care for these patients.

Effects of COVID-19 Infection and Vaccination on the Female Reproductive System: A Narrative Review. Balkan Med J 2023; 40:153-164. [PMID: 37114907 PMCID: PMC10175880 DOI: 10.4274/balkanmedj.galenos.2023.2023-3-4] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/01/2023] [Accepted: 04/06/2023] [Indexed: 04/29/2023] Open
Abstract
Several studies and research papers have been published to elucidate and understand the mechanism of the coronavirus disease 2019 (COVID-19) pandemic and its long-term effects on the human body. COVID-19 affects a number of organs, including the female reproductive system. However, less attention has been given to the effects of COVID-19 on the female reproductive system due to their low morbidity. The results of studies investigating the relationship between COVID-19 infection and ovarian function in women of reproductive age have shown the harmless involvement of COVID-19 infection. Several studies have reported the involvement of COVID-19 infection in oocyte quality, ovarian function, and dysfunctions in the uterine endometrium and the menstrual cycle. The findings of these studies indicate that COVID-19 infection negatively affects the follicular microenvironment and dysregulate ovarian function. Although the COVID-19 pandemic and female reproductive health have been studied in humans and animals, very few studies have examined how COVID-19 affects the female reproductive system. The objective of this review is to summarize the current literature and categorize the effects of COVID-19 on the female reproductive system, including the ovaries, uterus, and hormonal profiles. The effects on oocyte maturation, oxidative stress, which causes chromosomal instability and apoptosis in ovaries, in vitro fertilization cycle, high-quality embryos, premature ovarian insufficiency, ovarian vein thrombosis, hypercoagulable state, women’s menstrual cycle, the hypothalamus-pituitary-ovary axis, and sex hormones, including estrogen, progesterone, and the anti-Müllerian hormone, are discussed in particular.

Abstract
Background Urothelial cells exhibit increased expression of angiotensin-converting enzyme-2 receptor, which is the binding site of severe acute respiratory syndrome coronavirus 2 to cells. The frequency and distribution of genitourinary tract symptoms in patients diagnosed with coronavirus disease 2019 (COVID-19) is unknown. Objective We explored trends in genitourinary tract symptoms by gender and each of six pandemic waves in patients admitted for COVID-19, and related them with severity, death and length of hospitalization. Design Setting and Participants A retrospective study took place in our institution of COVID-19 admitted patients. Only patients with RT-PCR or antigen test confirmed SARS-CoV-2 infection were included. Demographic, clinical, and genitourinary symptoms were explored. Outcome Measurements and Statistical Analysis COVID-19 patients with genitourinary tract symptoms were compared with those without. Statistical comparisons were conducted by parametric and nonparametric tests for quantitative variables, and χ 2 test for qualitative variables. Results and limitations Out of a total of 4,661 COVID-19 patients, genitourinary symptoms were found in 21,1%. These symptoms were more frequent in patients admitted for longer than 30 days, except for urinary incontinence (UI) and erectile dysfunction (ED). Acute kidney injury (AKI) and urinary tract infections (UTI) had a higher presence in the 5th (16.7%; 12.8% respectively) and 3rd wave (13.3%; 12.6% respectively). Genitourinary symptoms were higher for those patients admitted in critical care units. Frequency of AKI, UI, UTI and acute urinary retention (AUR) were higher for patients who were finally deceased (26.2%; 3.5%; 13.6% and 3.6% respectively). Conclusions A high frequency of genitourinary symptoms in patients admitted for COVID-19 was observed, whose frequency and distribution varied according to pandemic waves. Specific genitourinary conditions were associated with worse outcomes and poorer prognosis.

Abstract
Since December 2019, the emergence of a new Severe Acute Respiratory Syndrome- coronavirus (SARS-CoV-2) has led to a global coronavirus pandemic disease (COVID-19), with devastating consequences for all healthcare worldwide, including urological care. COVID-19 has led to concern among urological healthcare workers about viral presence, detection and routes of transmission during routine clinical practice. The potential presence of (active) virus in bodily fluids of COVID-19 patients remains a continuing topic of debate. Therefore, we highlight viral detection methods and review the presence of SARS-CoV-2 in urine, feces, and semen. Finally, we discuss how excretion of virus particles through urological bodily fluids might be pivotal to epidemiologic monitoring and control of the disease.

Abstract
Bladder cancer as one of the main comorbid diseases might be more susceptible to develop COVID-19 infection with a higher mortality risk during the COVID-19 pandemic. The European Association of Urology (EAU) recommended a comprehensive panel for bladder cancer diagnosis and treatment during this global health problem. The urgent need for treatments of COVID-19 during the pandemic has persuaded researchers to evaluate the different medications, which may lead to drug shortages. Therefore, in this review paper, we have focused on the least recommendations of EAU about bladder cancer during of COVID-19 pandemic to provide a comprehensive panel for high-risk patients.

Abstract
Wastewater-based epidemiology (WBE) is a potential approach for determining the viral prevalence in a community. In the wake of the COVID-19 pandemic, researchers have begun to pay close attention to the presence of SARS-COV-2 RNA in various wastewaters. The potential for detecting SARS-CoV-2 RNA in hospital sewage could make it an invaluable resource for epidemiological studies. In this regard, two specialized hospitals dedicated to COVID-19 patients were chosen for this investigation. Both hospitals utilize the same wastewater treatment systems. The influent and effluents of the two hospitals were sampled in May and June of 2021, and the samples were evaluated for their chemical properties. According to the findings of this study, the wastewater qualities of the two studied hospitals were within the standard ranges. The sewage samples were concentrated using ultrafiltration and PEG precipitation techniques. The E and S genes were studied with RT-qPCR commercial kits. We found E gene of SARS-CoV-2 in 83.3% (5/6) and 66.6% (4/6) of wastewater samples from hospital 1 and hospital 2, respectively, using ultrafiltration concentration method. Wastewater samples taken after chlorine treatment accounted for 16.6% of all positive results. In addition, due to the small sample size, there was no significant correlation (p > 0.05) between the presence of SARS-CoV-2 in wastewater and the number of COVID-19 cases. Hospitals may be a source of SARS-CoV-2 pollution, thus it is important to monitor and enhance wastewater treatment systems to prevent the spread of the virus and safeguard the surrounding environment.

Abstract
Wastewater-based epidemiology is now widely used as an indirect tool to monitor the spread of SARS-CoV-2. In this study, five different sample matrices representing diverse phases of the wastewater treatment process were collected during the second wave of SARS-CoV-2 from two wastewater treatment plants (WWTPs) serving the Civil Hospital and Sacca Fisola island in Venice, Italy. Positive SARS-CoV-2 detections occurred at both WWTPs, and data on viral genome detection rate and quantification suggest that the pellet (i.e., the particulate resulting from the influent) is a sensitive matrix that permits reliable assessment of infection prevalence while reducing time to results. On the contrary, analysis of post-treatment matrices provides evidence of the decontamination efficacy of both WWTPs. Finally, direct sequencing of wastewater samples enabled us to identify B.1.177 and B.1.160 as the prevalent SARS-CoV-2 lineages circulating in Venice at the time of sampling. This study confirmed the suitability of wastewater testing for studying SARS-CoV-2 circulation and established a simplified workflow for the prompt detection and characterization of the virus.

Abstract
The COVID-19 associated acute kidney injury (CAKI) has emerged as a potential intricacy during the management of patients. Navigating the rapidly growing body of scientific literature on CAKI is challenging, and ongoing critical appraisal of this complication is essential. This study aimed to summarize and critically appraise the systematic reviews (SRs) on CAKI to inform the healthcare providers about its prevalence, risk factors and outcomes. All the SRs were searched in major databases (PubMed, EMBASE, Web of Science) from inception date to December 2021. This study followed SR of SRs methodology, all the records were screened, extracted and subjected to quality assessment by assessing the methodological quality of systematic reviews (AMSTAR-2). The extracted data were qualitatively synthesized and tabulated. This review protocol was registered in PROSPERO (CRD42022299444). Of 3,833 records identified; 42 SRs were included in this overview. The quality appraisal of the studies showed that 17 SRs were of low quality, while 8 moderate and 17 were of high-quality SRs. The incidence of CAKI ranged from 4.3% to 36.4% in overall COVID-19 patients, 36%-50% in kidney transplant recipients (KTRs), and up to 53% in severe or critical illness. Old age, male gender, cardiovascular disease, chronic kidney disease, diabetes mellitus and hypertension were frequently reported risk factors of CAKI. The need of renal replacement therapy (RRT) was up to 26.4% in overall COVID-19 patients, and 39% among those having CAKI. The occurrence of acute kidney injury (AKI) was found independent predictor of death, where mortality rate among CAKI patients ranged from 50% to 93%. This overview of SRs underscores that CAKI occurs frequently among COVID-19 patients and associated with high mortality, need of RRT and adverse outcomes. However, the confidence of these results is moderate to low which warrants the need of more SRs having established methodological standards.

Monitoring the evolution of SARS-CoV-2 on a Spanish university campus through wastewater analysis: A pilot project for the reopening strategy. THE SCIENCE OF THE TOTAL ENVIRONMENT 2022; 845:157370.

Abstract
Wastewater surveillance is a fast and cost-effective tool that enables tracing of both symptomatic and asymptomatic transmission of SARS-CoV-2. In this paper, a pilot program carried out at the University Jaume I for monitoring the trends of the presence of SARS-CoV-2 in wastewater. To the best of our knowledge, this is the first such project conducted on a university campus in Spain. Wastewater samples (n = 838) were collected when students returned to campus, from October 2020 until August 2021, at a confluence sewer point and at the building level including different academic departments and services, the library, administration offices and the university student residence. It has been observed that the probability of SARS-CoV-2 RNA detection in wastewater depended on COVID-19 incidence on campus and visitors/occupants of the buildings i.e., high-, or low-traffic buildings with high or low frequency of potential contacts. Moreover, the third wave in Spain (after Christmas 2020) and an outbreak that occurred at the university student's residence could be carefully followed, allowing confirmation of the end of the outbreak. In addition, viral variants (i.e., mutations and linages) from selected time points were detected by sequencing and gave an indication of the evolution of the virus over time. The results illustrate the potential of wastewater-based epidemiology to provide an early warning for SARS-CoV-2 within the university, especially in buildings with low traffic and more defined populations, like the student residence. The strategy and experience gathered in this study will allow for implementation of improvements for reliable monitoring in the future.

Quantifying the Relationship between SARS-CoV-2 Wastewater Concentrations and Building-Level COVID-19 Prevalence at an Isolation Residence: A Passive Sampling Approach. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2022; 19:11245.

Abstract
SARS-CoV-2 RNA loads can be detected in the excreta of individuals with COVID-19 and have demonstrated positive correlations with clinical infection trends. Consequently, wastewater-based epidemiology (WBE) approaches have been implemented globally as a public health surveillance tool to monitor community-level prevalence of infections. The majority of wastewater specimens are gathered as either composite samples via automatic samplers (autosamplers) or grab samples. However, autosamplers are expensive and can be challenging to maintain in cold weather, while grab samples are particularly susceptible to temporal variation when sampling sewage directly from complex matrices outside residential buildings. Passive sampling can provide an affordable, practical, and scalable sampling system while maintaining a reproducible SARS-CoV-2 signal. In this regard, we deployed tampons as passive samplers outside of a COVID-19 isolation unit (a segregated residence hall) at a university campus from 1 February 2021-21 May 2021. Samples (n = 64) were collected 3-5 times weekly and remained within the sewer for a median duration of 24 h. SARS-CoV-2 RNA was quantified using reverse-transcription quantitative polymerase chain reaction (RT-qPCR) targeting the N1 and N2 gene fragments. We quantified the mean viral load captured per individual and the association between the daily viral load and total persons, adjusting for covariates using multivariable models to provide a baseline estimate of viral shedding. Samples were processed through two distinct laboratory pipelines on campus, yielding highly correlated N2 concentrations. Data obtained here highlight the success of passive sampling utilizing tampons to capture SARS-CoV-2 in wastewater coming from a COVID-19 isolation residence, indicating that this method can help inform building-level public health responses.

Abstract
SARS-CoV-2 infection arose in 2019 and has changed life as we know it. With our ever-advancing knowledge, therapies, and vaccines, more functions of the SARS-CoV-2 virus are being investigated outside of its pulmonary invasion. Here, we set out to review the current and pertinent literature on the impact of SARS-CoV-2 on the male genitourinary system including the bladder, lower urinary tract, prostate, testis, and penis. The biggest newsworthy stake was if SARS-CoV-2 could be transmitted through semen. Although initially thought to occur, more recent studies have opposed this hypothesis. Outside of the reproductive spread of SARS-CoV-2, multiple studies in this review highlight where the virus resides and what effect it may be having on this genitourinary system including increased voiding problems, viral persistence months after systemic clearance, and rare penile complications post-infection. Long-term outcomes are still needed to fully understand how SARS-CoV-2 infection can alter the genitourinary system.

Abstract
Many reports have documented that the presence of SARS-CoV-2 RNA in the influents of municipal wastewater treatment plants (WWTP) correlates with the actual epidemic situation in a given city. However, few data have been reported thus far on measurements upstream of WWTPs, i.e. throughout the sewer network. In this study, the monitoring of the presence of SARS-CoV-2 RNA in Prague wastewater was carried out at selected locations of the Prague sewer network from August 2020 through May 2021. Various locations such as residential areas of various sizes, hospitals, city center areas, student dormitories, transportation hubs (airport, bus terminal), and commercial areas were monitored together with four of the main Prague sewers. The presence of SARS-CoV-2 RNA was determined by reverse transcription - multiplex quantitative polymerase chain reaction (RT-mqPCR) after the precipitation of nucleic acids with PEG 8,000 and RNA isolation with TRIzol™ Reagent. The number of copies of the gene encoding SARS-CoV-2 nucleocapsid (N1) per liter of wastewater was compared with the number of officially registered COVID-19 cases in Prague. Although the data obtained by sampling wastewater from the major Prague sewers were more consistent than those obtained from the small sewers, the correlation between wastewater-based and clinical-testing data was also good for the residential areas with more than 7,000 registered inhabitants. It was shown that monitoring SARS-CoV-2 RNA in wastewater sampled from small sewers could identify isolated occurrences of COVID-19-positive cases in local neighborhoods. This can be very valuable while tracking COVID-19 hotspots within large cities.

Pasteurization, storage conditions and viral concentration methods influence RT-qPCR detection of SARS-CoV-2 RNA in wastewater. THE SCIENCE OF THE TOTAL ENVIRONMENT 2022; 821:153228. [PMID: 35090920 PMCID: PMC8788100 DOI: 10.1016/j.scitotenv.2022.153228] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/21/2021] [Revised: 01/12/2022] [Accepted: 01/13/2022] [Indexed: 05/05/2023]
Abstract
The COVID-19 pandemic presents many public health challenges including the tracking of infected individuals from local to regional scales. Wastewater surveillance of viral RNA has emerged as a complementary approach to track and monitor the presence of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) virus in a variety of communities of different land use and population size. In the present study, we investigate how five different parameters (pasteurization, storage temperature, storage time, polyethylene glycol (PEG) concentration, and pellet mass) affect the detection of the SARS-CoV-2 N gene and fecal abundance indicator pepper mild mottle virus (PMMoV) gene. Pre-treatment of 24-h composite wastewater samples (n = 14) by pasteurization at 60 °C resulted in a significant reduction of total RNA concentration and copies of the SARS-CoV-2 N gene copies/L (paired Student's t-test, P < 0.05). Comparing the wastewater samples collected from 6 wastewater treatment plants (WWTPs) for a storage period of 7 and 14 days at 4 °C, -20 °C and -80 °C, demonstrated a decrease in SARS-CoV-2 N gene copies/L when samples were stored for 14 days at -20 °C. Polyethylene glycol-NaCl for purification and concentration of viral particles from the wastewater samples demonstrated that a short PEG incubation of 2 h during centrifugation at 4 °C was sufficient for the consistent detection of the SARS-CoV-2 N gene from a 30 mL sample volume. Combined, this paper presents method recommendations for developing a reliable, accurate, sensitive, and reproducible estimation of the SARS-CoV-2 virus in diverse domestic wastewater samples.

Abstract
PURPOSE OF REVIEW The Coronavirus disease 2019 (COVID-19) pandemic has led to uncertainty on the optimal management for prostate cancer (PCa). This narrative review aims to shed light on the optimal diagnosis and management of patients with or suspected to have PCa. RECENT FINDINGS Faecal-oral or aerosol transmission is possible during prostate procedures; caution must be in place when performing digital rectal examinations, transrectal ultrasound-guided prostate biopsies and prostate surgeries requiring general anaesthesia. Patients must also be triaged using preoperative polymerase chain reaction tests for COVID-19. COVID-19 has accelerated the adoption of multiparametric Magnetic Resonance Imaging (MRI), reducing the need for prostate biopsy unless when absolutely indicated, and the risk of COVID-19 spread can be reduced. Combined with prostate-specific antigen (PSA) density, amongst other factors, multiparametric MRI could reduce unnecessary biopsies in patients with little chance of clinically significant PCa. Treatment of PCa should be stratified by the risk level and preferences of the patient. COVID-19 has accelerated the development of telemedicine and clinicians should utilise safe and effective teleconsultations to protect themselves and their patients. SUMMARY COVID-19 transmission during prostate procedures is possible. Patients with a Prostate Imaging-Reporting and Data System (PI-RADS) of <3 and PSA density <0.15 ng/ml/ml are deemed low-risk and are safe to undergo surveillance without MRI-targeted biopsy. Intermediate- or high-risk patients should be offered definitive treatment within four months or 30days of diagnosis to avoid compromising treatment outcomes; three-month courses of neoadjuvant androgen deprivation therapy can be considered when a delay of surgery is anticipated.

Quantifying the relationship between SARS-CoV-2 wastewater concentrations and building-level COVID-19 prevalence at an isolation residence using a passive sampling approach. MEDRXIV : THE PREPRINT SERVER FOR HEALTH SCIENCES 2022:2022.04.07.22273534.

Abstract
UNLABELLED SARS-CoV-2 RNA can be detected in the excreta of individuals with COVID-19 and has demonstrated a positive correlation with various clinical parameters. Consequently, wastewater-based epidemiology (WBE) approaches have been implemented globally as a public health surveillance tool to monitor the community-level prevalence of infections. Over 270 higher education campuses monitor wastewater for SARS-CoV-2, with most gathering either composite samples via automatic samplers (autosamplers) or grab samples. However, autosamplers are expensive and challenging to manage with seasonal variability, while grab samples are particularly susceptible to temporal variation when sampling sewage directly from complex matrices outside residential buildings. Prior studies have demonstrated encouraging results utilizing passive sampling swabs. Such methods can offer affordable, practical, and scalable alternatives to traditional methods while maintaining a reproducible SARS-CoV-2 signal. In this regard, we deployed tampons as passive samplers outside of a COVID-19 isolation unit (a segregated residence hall) at a university campus from February 1, 2021 â€" May 21, 2021. Samples were collected several times weekly and remained within the sewer for a minimum of 24 hours (n = 64). SARS-CoV-2 RNA was quantified using reverse transcription-quantitative polymerase chain reaction (RT-qPCR) targeting the viral N1 and N2 gene fragments. We quantified the mean viral load captured per individual and the association between the daily viral load and total persons, adjusting for covariates using multivariable models to provide a baseline estimate of viral shedding. Samples were processed through two distinct laboratory pipelines on campus, yielding highly correlated N2 concentrations. Data obtained here highlight the success of passive sampling utilizing tampons to capture SARS-CoV-2 in wastewater coming from a COVID-19 isolation residence, indicating that this method can help inform public health responses in a range of settings. HIGHLIGHTS Daily SARS-CoV-2 RNA loads in building-level wastewater were positively associated with the total number of COVID-19 positive individuals in the residenceThe variation in individual fecal shedding rates of SARS-CoV-2 extended four orders of magnitudeWastewater sample replicates were highly correlated using distinct processing pipelines in two independent laboratoriesWhile the isolation residence was occupied, SARS-CoV-2 RNA was detected in all passive samples.

The changing trends of image-guided biopsy of small renal masses before intervention-an analysis of European multinational prospective EuRECA registry. Eur Radiol 2022; 32:4667-4678. [PMID: 35122492 PMCID: PMC8817647 DOI: 10.1007/s00330-022-08556-2] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/16/2021] [Revised: 12/01/2021] [Accepted: 12/26/2021] [Indexed: 12/26/2022]
Abstract
Objectives To evaluate the use of pre-cryoablation biopsy for small renal masses (SRMs) and the effects of increasing uptake on histological results of treated SRMs. Methods From 2015 to 2019, patients with sporadic T1N0M0 SRMs undergoing percutaneous, laparoscopic, or open cryoablation from 14 European institutions within the European Registry for Renal Cryoablation (EuRECA) were included for the retrospective analysis. Univariate and multivariate logistic models were used to evaluate the trends, histological results, and the factors influencing use of pre-cryoablation biopsy. Results In total, 871 patients (median (IQR) age, 69 (14), 298 women) undergoing cryoablation were evaluated. The use of pre-cryoablation biopsy has significantly increased from 42% (65/156) in 2015 to 72% (88/122) in 2019 (p < 0.001). Patients treated for a benign histology are significantly more likely to have presented later in the trend, where pre-cryoablation biopsy is more prevalent (OR: 0.64, 95% CI 0.51–0.81, p < 0.001). Patients treated for undiagnosed histology are also significantly less likely to have presented in 2018 compared to 2016 (OR 0.31, 95% CI 0.10–0.97, p = 0.044). Patients aged 70+ are less likely to be biopsies pre-cryoablation (p < 0.05). R.E.N.A.L. nephrometry score of 10+ and a Charlson Comorbidity Index > 1 are factors associated with lower likelihood to not have received a pre-cryoablation biopsy (p < 0.05). Conclusion An increased use of pre-cryoablation biopsy was observed and cryoablation patients treated with a benign histology are more likely to have presented in periods where pre-cryoablation biopsy is not as prevalent. Comparative studies are needed to draw definitive conclusions on the effect of pre-cryoablation biopsy on SRM treatments. Key Points • The use of biopsy pre-ablation session has increased significantly from 42% of all patients in 2015 to 74% in 2019. • Patients are less likely to be treated for a benign tumour if they presented later in the trend, where pre-cryoablation biopsy is more prevalent, compared to later in the trend (OR 0.64, 95% CI 0.51–0.81, p < 0.001). • Patients with comorbidities or a complex tumour (R.E.N.A.L. nephrometry score > 10) are less likely to not undergo biopsy as a separate session to cryoablation.

Abstract
The COVID 19 pandemic has forced us to rethink our management strategies for surgical diseases. Patients with COVID 19 have increased risk of morbidity and mortality after surgical intervention. Emphysematous pyelonephritis (EPN) is often seen in diabetics and can be a life threatening condition. All patients require immediate treatment with antibiotics and close monitoring. Bilateral EPN is a rare entity seen in less than 10% of patients. We present a case of bilateral EPN in a COVID positive patient which was successfully managed conservatively. A 70 year old hypertensive female, presented to us with fever, breathlessness, loss of appetite, generalised weakness requiring oxygen supplementation & was diagnosed with COVID 19. Bilateral EPN (Grade 4) with perinephric collections was found on evaluation for acute kidney injury. She underwent bilateral pig tail insertion followed by bilateral DJ stenting after stabilization. She recovered dramatically, blood parameters improved and was discharged. At 1 year of follow up, patient was doing well. In the present COVID-19 pandemic where case selection for surgical intervention is crucial, we would like to highlight how a conservative approach for even Class 4 EPN is feasible after weighing the risks and benefits of the same. Patients can be spared the immediate morbidity and mortality risks due to surgical intervention during COVID 19 infection. Triaging surgical intervention can also help in better utilization of critical care facilities and man power, both invaluable in the ongoing crisis.

Abstract
COVID-19, the coronavirus disease 2019; SARS-CoV-2, the coronavirus 2; ACE2, angiotensin converting enzyme 2; S protein, spiked glycoprotein; TMPRSS2, transmembrane serine protease 2; WHO, World Health Organization. Purpose: Although the coronavirus disease 2019 (COVID-19) pandemic, caused by the severe acute respiratory syndrome coronavirus 2, has been viably controlled in China, a new normal in healthcare strategies has become standard in China and worldwide. We conducted a questionnaire study to disseminate the experience from China in terms of urology outpatient prevention and control measures under standardized prevention policies against COVID-19. Participants and Methods: From May 3, 2020 to June 25, 2020, we conducted an anonymous cross-sectional questionnaire study, focused on the status of and experiences with outpatient urology prevention and control measures during the COVID-19 pandemic. The targeted respondents were urologists in mainland China, covering all levels of hospitals and clinics. Results: A total of 216 (97%) valid responses were collected. We found that 183 (85%) respondents were from outside of Hubei province in China. One-hundred-and-fifty-eight (73%) respondents believed that SARS-CoV-2 could be detected in urine, and that protection against urine exposure was needed. Over 80% of respondents recommended WeChat application or similar online video meetings for virtual outpatient consultations. The suggested flowcharts and recommendations to prevent new cases were easy to understand and approved by most physicians, which could provide reference for outpatient prevention and control. We still need to make adequate preparations under the new normal of the COVID-19 Epidemic, especially for those suspected of being infected. Conclusions: Although the scientific validation of the questionnaire is limited, it provides a first snapshot of the experiences relating to the prevention and control measures in urology clinics in China, and can inform future policies in this field.

Abstract
The COVID-19 pandemic has created an urgent need for robust, scalable monitoring tools supporting stratification of high-risk patients. This research aims to develop and validate prediction models, using the UK Biobank, to estimate COVID-19 mortality risk in confirmed cases. From the 11,245 participants testing positive for COVID-19, we develop a data-driven random forest classification model with excellent performance (AUC: 0.91), using baseline characteristics, pre-existing conditions, symptoms, and vital signs, such that the score could dynamically assess mortality risk with disease deterioration. We also identify several significant novel predictors of COVID-19 mortality with equivalent or greater predictive value than established high-risk comorbidities, such as detailed anthropometrics and prior acute kidney failure, urinary tract infection, and pneumonias. The model design and feature selection enables utility in outpatient settings. Possible applications include supporting individual-level risk profiling and monitoring disease progression across patients with COVID-19 at-scale, especially in hospital-at-home settings.

Current systematic reviews and meta-analyses of COVID-19. World J Virol 2021; 10:182-208. [PMID: 34367933 PMCID: PMC8316876 DOI: 10.5501/wjv.v10.i4.182] [Citation(s) in RCA: 17] [Impact Index Per Article: 5.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/24/2021] [Revised: 04/13/2021] [Accepted: 06/03/2021] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND Coronavirus disease 2019 (COVID-19) has left a significant impact on the world's health, economic and political systems; as of November 20, 2020, more than 57 million people have been infected worldwide, with over 1.3 million deaths. While the global spotlight is currently focused on combating this pandemic through means ranging from finding a treatment among existing therapeutic agents to inventing a vaccine that can aid in halting the further loss of life.
AIM To collect all systematic reviews and meta-analyses published related to COVID-19 to better identify available evidence, highlight gaps in knowledge, and elucidate further meta-analyses and umbrella reviews that are yet to be performed.
METHODS We explored studies based on systematic reviews and meta-analyses with the key-terms, including severe acute respiratory syndrome (SARS), SARS virus, coronavirus disease, COVID-19, and SARS coronavirus-2. The included studies were extracted from Embase, Medline, and Cochrane databases. The publication timeframe of included studies ranged between January 01, 2020, to October 30, 2020. Studies that were published in languages other than English were not considered for this systematic review. The finalized full-text articles are freely accessible in the public domain.
RESULTS Searching Embase, Medline, and Cochrane databases resulted in 1906, 669, and 19 results, respectively, that comprised 2594 studies. 515 duplicates were subsequently removed, leaving 2079 studies. The inclusion criteria were systematic reviews or meta-analyses. 860 results were excluded for being a review article, scope review, rapid review, panel review, or guideline that produced a total of 1219 studies. After screening articles were categorized, the included articles were put into main groups of clinical presentation, epidemiology, screening and diagnosis, severity assessment, special populations, and treatment. Subsequently, there was a second subclassification into the following groups: gastrointestinal, cardiovascular, neurological, stroke, thrombosis, anosmia and dysgeusia, ocular manifestations, nephrology, cutaneous manifestations, D-dimer, lymphocyte, anticoagulation, antivirals, convalescent plasma, immunosuppressants, corticosteroids, hydroxychloroquine, renin-angiotensin-aldosterone system, technology, diabetes mellitus, obesity, pregnancy, children, mental health, smoking, cancer, and transplant.
CONCLUSION Among the included articles, it is clear that further research is needed regarding treatment options and vaccines. With more studies, data will be less heterogeneous, and statistical analysis can be better applied to provide more robust clinical evidence. This study was not designed to give recommendations regarding the management of COVID-19.

Abstract
Coronavirus disease 2019 (COVID-19) can be considered a systemic disease with a specific tropism for the vascular system, in which the alterations of the microcirculation have an important pathogenetic role. The lungs are the main organ involved in COVID-19, and severe progressive respiratory failure is the leading cause of death in the affected patients; however, many other organs can be involved with variable clinical manifestations. Concerning abdominal manifestations, the gastrointestinal tract and the hepatobiliary system are mainly affected, although the pancreas, urinary tract and spleen may also be involved. The most common gastrointestinal symptoms are loss of appetite, followed by nausea and vomiting, diarrhea and abdominal pain. Gastrointestinal imaging findings include bowel wall thickening, sometimes associated with hyperemia and mesenteric thickening, fluid-filled segments of the large bowel and rarely intestinal pneumatosis and ischemia. Hepatic involvement manifests as an increase in the enzymatic levels of alanine aminotransferase, aspartate aminotransferase, serum bilirubin and γ-glutamyl transferase with clinical manifestations in most cases mild and transient. The most frequent radiological features are hepatic steatosis, biliary sludge and gallstones. Edematous acute pancreatitis, kidney infarct and acute kidney injury from acute tubular necrosis have been described more rarely in COVID-19. Lastly, splenic involvement is characterized by splenomegaly and by the development of solitary or multifocal splenic infarcts with classic wedge-shaped or even rounded morphology, with irregular or smooth profiles. In summary, the abdominal radiological findings of COVID-19 are nonspecific and with poor pathological correlation reported in the literature. Ultrasound and particularly computed tomography with multiphasic acquisition are the diagnostic methods mainly utilized in COVID-19 patients with abdominal clinical symptoms and signs. Although radiological signs are not specific of abdominal and gastrointestinal involvement, the diagnostic imaging modalities and in particular computed tomography are helpful for the clinician in the management, evaluation of the severity and evolution of the COVID-19 patients.

Abstract
PURPOSE OF REVIEW To investigate the possible effects of severe acute respiratory syndrome-related coronavirus 2 (SARS-CoV-2) on kidney function and assess the rate of viral ribonucleic acid (RNA) shedding/detection in urine. RECENT FINDINGS Most of the research on the topic suggests that for the moment our ability to estimate whether SARS-CoV-2 is a direct causative agent in acute kidney injury (AKI) or whether it has a cytokine storm effect is limited. During our prospective assessment of 333 patients with COronaVIrus Disease 2019 (COVID-19) it was found that frequency of AKI of 9.6% (32 cases). Despite previous data suggestive of the ability to detect SARS-CoV-2 in urine, we were unable to identify any traces of messenger ribonucleic acid (mRNA) in our group. Both COVID-19 severity (odds ratio, OR = 23.09, confidence interval, CI 7.89-67.57, P < 0.001) and chronic kidney disease (CKD) history (OR = 7.17, CI 2.09-24.47, P = 0.002) were associated with the AKI rate. SUMMARY AKI is a relatively frequent condition for patients with COVID-19 and is normally correlated with the severity of the disease and the patient's history of CKD. The available data fail to address whether SARS-CoV-2 mRNA is present in urine, whereas our prospective trial data suggest that mRNA is undetectable in urine irrespective of the severity of the disease.

Abstract
Simple Summary We reviewed the evidence available for postponing or delaying cancer surgery for localised prostate cancer. Watchful waiting is an acceptable option in low-risk patients. Evidence is uncertain in postponing surgery, but conservative estimates suggest delays of over 5 months, 4 months, and 30 days for low-, intermediate-, and high-risk patients, respectively, can lead to worse survival outcomes. Neoadjuvant therapy can shrink the tumours prior to surgery and can be a useful adjunct in delaying surgery for, at the most, 3 months. Abstract External factors, such as the coronavirus disease 2019 (COVID-19), can lead to cancellations and backlogs of cancer surgeries. The effects of these delays are unclear. This study summarised the evidence surrounding expectant management, delay radical prostatectomy (RP), and neoadjuvant hormone therapy (NHT) compared to immediate RP. MEDLINE and EMBASE was searched for randomised controlled trials (RCTs) and non-randomised controlled studies pertaining to the review question. Risks of biases (RoB) were evaluated using the RoB 2.0 tool and the Newcastle–Ottawa Scale. A total of 57 studies were included. Meta-analysis of four RCTs found overall survival and cancer-specific survival were significantly worsened amongst intermediate-risk patients undergoing active monitoring, observation, or watchful waiting but not in low- and high-risk patients. Evidence from 33 observational studies comparing delayed RP and immediate RP is contradictory. However, conservative estimates of delays over 5 months, 4 months, and 30 days for low-risk, intermediate-risk, and high-risk patients, respectively, have been associated with significantly worse pathological and oncological outcomes in individual studies. In 11 RCTs, a 3-month course of NHT has been shown to improve pathological outcomes in most patients, but its effect on oncological outcomes is apparently limited.

Urine biomarkers for the prediction of mortality in COVID-19 hospitalized patients. Sci Rep 2021; 11:11134. [PMID: 34045530 PMCID: PMC8159957 DOI: 10.1038/s41598-021-90610-y] [Citation(s) in RCA: 12] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/09/2021] [Accepted: 05/10/2021] [Indexed: 01/08/2023] Open
Abstract
Risk factors associated with severity and mortality attributable to COVID-19 have been reported in different cohorts, highlighting the occurrence of acute kidney injury (AKI) in 25% of them. Among other, SARS-CoV-2 targets renal tubular cells and can cause acute renal damage. The aim of the present study was to evaluate the usefulness of urinary parameters in predicting intensive care unit (ICU) admission, mortality and development of AKI in hospitalized patients with COVID-19. Retrospective observational study, in a tertiary care hospital, between March 1st and April 19th, 2020. We recruited adult patients admitted consecutively and positive for SARS-CoV-2. Urinary and serum biomarkers were correlated with clinical outcomes (AKI, ICU admission, hospital discharge and in-hospital mortality) and evaluated using a logistic regression model and ROC curves. A total of 199 COVID-19 hospitalized patients were included. In AKI, the logistic regression model with a highest area under the curve (AUC) was reached by the combination of urine blood and previous chronic kidney disease, with an AUC of 0.676 (95%CI 0.512-0.840; p = 0.023); urine specific weight, sodium and albumin in serum, with an AUC of 0.837 (95% CI 0.766-0.909; p < 0.001) for ICU admission; and age, urine blood and lactate dehydrogenase levels in serum, with an AUC of 0.923 (95%CI 0.866-0.979; p < 0.001) for mortality prediction. For hospitalized patients with COVID-19, renal involvement and early alterations of urinary and serum parameters are useful as prognostic factors of AKI, the need for ICU admission and death.

Delayed surgery for localised and metastatic renal cell carcinoma: a systematic review and meta-analysis for the COVID-19 pandemic. World J Urol 2021; 39:4295-4303. [PMID: 34031748 PMCID: PMC8143063 DOI: 10.1007/s00345-021-03734-1] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/17/2021] [Accepted: 05/13/2021] [Indexed: 12/04/2022] Open
Abstract
Purpose The COVID-19 pandemic has led to the cancellation or deferment of many elective cancer surgeries. We performed a systematic review on the oncological effects of delayed surgery for patients with localised or metastatic renal cell carcinoma (RCC) in the targeted therapy (TT) era. Method The protocol of this review is registered on PROSPERO(CRD42020190882). A comprehensive literature search was performed on Medline, Embase and Cochrane CENTRAL using MeSH terms and keywords for randomised controlled trials and observational studies on the topic. Risks of biases were assessed using the Cochrane RoB tool and the Newcastle–Ottawa Scale. For localised RCC, immediate surgery [including partial nephrectomy (PN) and radical nephrectomy (RN)] and delayed surgery [including active surveillance (AS) and delayed intervention (DI)] were compared. For metastatic RCC, upfront versus deferred cytoreductive nephrectomy (CN) were compared. Results Eleven studies were included for quantitative analysis. Delayed surgery was significantly associated with worse cancer-specific survival (HR 1.67, 95% CI 1.23–2.27, p < 0.01) in T1a RCC, but no significant difference was noted for overall survival. For localised ≥ T1b RCC, there were insufficient data for meta-analysis and the results from the individual reports were contradictory. For metastatic RCC, upfront TT followed by deferred CN was associated with better overall survival when compared to upfront CN followed by deferred TT (HR 0.61, 95% CI 0.43–0.86, p < 0.001). Conclusion Noting potential selection bias, there is insufficient evidence to support the notion that delayed surgery is safe in localised RCC. For metastatic RCC, upfront TT followed by deferred CN should be considered. Supplementary Information The online version contains supplementary material available at 10.1007/s00345-021-03734-1.

Abstract
OBJECTIVE Severe acute respiratory syndrome coronavirus-2 acute kidney injury is a condition that in many ways resembles classical acute kidney injury. The pathophysiology appears to be multifactorial, and accordingly, our main objective was to review possible components of this form of acute kidney injury. DATA SOURCES Literature review. DATA SYNTHESIS Our principal observation was that the various components of severe acute respiratory syndrome coronavirus-2 acute kidney injury appear to be relatively similar to the classical forms. Temporality of injury is an important factor but is not specific to severe acute respiratory syndrome coronavirus-2 acute kidney injury. Several insults hit the kidney at different moments in the course of disease, some occurring prior to hospital admission, whereas others take place at various stages during hospitalization. CONCLUSIONS AND RELEVANCE Treatment of severe acute respiratory syndrome coronavirus-2 acute kidney injury cannot be approached in a "one-size-fits-all" manner. The numerous mechanisms involved do not occur simultaneously, leading to a multiple hit model that may contribute to the prevalence and severity of acute kidney injury. A personalized approach to each patient with acute kidney injury based on the timing and severity of disease is necessary in order to provide appropriate treatment. Although data from the literature regarding the previous coronavirus infections can give some insights, more studies are needed to explore the different mechanisms of acute kidney injury occurring as a result of severe acute respiratory syndrome coronavirus-2.

Perioperative outcomes of patients undergoing urological elective surgery during the COVID-19 pandemic: a national overview across 28 Italian institutions. Cent European J Urol 2021; 74:259-268. [PMID: 34336248 PMCID: PMC8318031 DOI: 10.5173/ceju.2021.0374] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/24/2020] [Revised: 03/02/2021] [Accepted: 04/08/2021] [Indexed: 12/11/2022] Open
Abstract
Introduction The aim of this study was to assess the safety of elective urological surgery performed during the pandemic by estimating the prevalence of COVID-19-like symptoms in the postoperative period and its correlation with perioperative and clinical factors. Material and methods In this multicenter, observational study we recorded clinical, surgical and postoperative data of consecutive patients undergoing elective urological surgery in 28 different institutions across Italy during initial stage of the COVID-19 pandemic (between February 24 and March 30, 2020, inclusive). Results A total of 1943 patients were enrolled. In 12%, 7.1%, 21.3%, 56.7% and 2.6% of cases an open, laparoscopic, robotic, endoscopic or percutaneous surgical approach was performed, respectively. Overall, 166 (8.5%) postoperative complications were registered, 77 (3.9%) surgical and 89 (4.6%) medical. Twenty-eight (1.4%) patients were readmitted to hospital after discharge and 13 (0.7%) died. In the 30 days following discharge, fever and respiratory symptoms were recorded in 101 (5.2%) and 60 (3.1%) patients. At multivariable analysis, not performing nasopharyngeal swab at hospital admission (HR 2.3; CI 95% 1.01–5.19; p = 0.04) was independently associated with risk of developing postoperative medical complications. Number of patients in the facility was confirmed as an independent predictor of experiencing postoperative respiratory symptoms (p = 0.047, HR:1.12; CI95% 1.00–1.05), while COVID-19-free type of hospitalization facility was a strong independent protective factor (p = 0.02, HR:0.23, CI95% 0.07–0.79). Conclusions Performing elective surgery during the COVID-19 pandemic does not seem to affect perioperative outcomes as long as proper preventive measures are adopted, including nasopharyngeal swab before hospital admission and hospitalization in dedicated COVID-19-free facilities.

Abstract
The Coronavirus Disease-19 (COVID-19) pandemic has caused more than 100,000,000 cases of coronavirus infection in the world in just a year, of which there were 2 million deaths. Its clinical picture is characterized by pulmonary involvement that culminates, in the most severe cases, in acute respiratory distress syndrome (ARDS). However, COVID-19 affects other organs and systems, including cardiovascular, urinary, gastrointestinal, and nervous systems. Currently, unique-drug therapy is not supported by international guidelines. In this context, it is important to resort to adjuvant therapies in combination with traditional pharmacological treatments. Among natural bioactive compounds, palmitoylethanolamide (PEA) seems to have potentially beneficial effects. In fact, the Food and Drug Administration (FDA) authorized an ongoing clinical trial with ultramicronized (um)-PEA as an add-on therapy in the treatment of Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2) infection. In support of this hypothesis, in vitro and in vivo studies have highlighted the immunomodulatory, anti-inflammatory, neuroprotective and pain-relieving effects of PEA, especially in its um form. The purpose of this review is to highlight the potential use of um-PEA as an adjuvant treatment in SARS-CoV-2 infection.

Estimating the minimum number of SARS-CoV-2 infected cases needed to detect viral RNA in wastewater: To what extent of the outbreak can surveillance of wastewater tell us? ENVIRONMENTAL RESEARCH 2021; 195:110748.

Abstract
There is increasing interest in wastewater-based epidemiology (WBE) of SARS-CoV-2 RNA to serve as an early warning system for a community. Despite successful detection of SARS-CoV-2 RNA in wastewaters sampled from multiple locations, there is still no clear idea on the minimal number of cases in a community that are associated with a positive detection of the virus in wastewater. To address this knowledge gap, we sampled wastewaters from a septic tank (n = 57) and biological activated sludge tank (n = 52) located on-site of a hospital. The hospital is providing treatment for SARS-CoV-2 infected patients, with the number of hospitalized patients per day known. It was observed that depending on which nucleocapsid gene is targeted by means of RT-qPCR, a range of 253-409 positive cases out of 10,000 persons are required prior to detecting RNA SARS-CoV-2 in wastewater. There was a weak correlation between N1 and N2 gene abundances in wastewater with the number of hospitalized cases. This correlation was however not observed for N3 gene. The frequency of detecting N1 and N2 gene in wastewater was also higher than that for N3 gene. Furthermore, nucleocapsid genes of SARS-CoV-2 were detected at lower frequency in the partially treated wastewater than in the septic tank. In particular, N1 gene abundance was associated with water quality parameters such as total organic carbon and pH. In instances of positive detection, the average abundance of N1 and N3 genes in the activated sludge tank were reduced by 50 and 70% of the levels detected in septic tank, suggesting degradation of the SARS-CoV-2 gene fragments already occurring in the early stages of the wastewater treatment process.

Abstract
BACKGROUND Severe acute respiratory syndrome (SARS) and coronavirus disease 2019 (COVID-19) are closely related. The effect of AKI on the clinical outcomes of these two conditions is unclear. METHODS This retrospective, territory-wide cohort study used an electronic public healthcare database in Hong Kong to identify patients with SARS or COVID-19 by diagnosis codes, virologic results, or both. The primary endpoint was a composite of intensive care unit admission, use of invasive mechanical ventilation, and/or death. RESULTS We identified 1670 patients with SARS and 1040 patients with COVID-19 (median ages, 41 versus 35 years, respectively). Among patients with SARS, 26% met the primary endpoint versus 5.3% of those with COVID-19. Diabetes mellitus, abnormal liver function, and AKI were factors significantly associated with the primary endpoint among patients with either SARS or COVID-19. Among patients with SARS, 7.9%, 2.1%, and 3.7% developed stage 1, stage 2, and stage 3 AKI, respectively; among those with COVID-19, 6.6%, 0.4%, and 1.1% developed stage 1, stage 2, and stage 3 AKI, respectively. In both groups, factors significantly associated with AKI included diabetes mellitus and hypertension. Among patients with AKI, those with COVID-19 had a lower rate of major adverse clinical outcomes versus patients with SARS. Renal function recovery usually occurred within 30 days after an initial AKI event. CONCLUSIONS AKI rates were higher among patients with SARS than those with COVID-19. AKI was associated with major adverse clinical outcomes for both diseases. Patients with diabetes mellitus and abnormal liver function were also at risk of developing severe consequences after SARS and COVID-19 infection.

SARS-CoV-2 RNA monitoring in wastewater as a potential early warning system for COVID-19 transmission in the community: A temporal case study. THE SCIENCE OF THE TOTAL ENVIRONMENT 2021; 761:144216.

Abstract
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the virus which causes coronavirus disease (COVID-19), has spread rapidly across the globe infecting millions of people and causing significant health and economic impacts. Authorities are exploring complimentary approaches to monitor this infectious disease at the community level. Wastewater-based epidemiology (WBE) approaches to detect SARS-CoV-2 RNA in municipal wastewater are being implemented worldwide as an environmental surveillance approach to inform health authority decision-making. Owing to the extended excretion of SARS-CoV-2 RNA in stool, WBE can surveil large populated areas with a longer detection window providing unique information on the presence of pre-symptomatic and asymptomatic cases that are unlikely to be screened by clinical testing. Herein, we analysed SARS-CoV-2 RNA in 24-h composite wastewater samples (n = 63) from three wastewater treatment plants (WWTPs) in Brisbane, Queensland, Australia from 24th of February to 1st of May 2020. A total of 21 samples were positive for SARS-CoV-2, ranging from 135 to 11,992 gene copies (GC)/100 mL of wastewater. Detections were made in a Southern Brisbane WWTP in late February 2020, up to three weeks before the first clininal case was reported there. Wastewater samples were generally positive during the period with highest caseload data. The positive SARS-CoV-2 RNA detection in wastewater while there were limited clinical reported cases demonstrates the potential of WBE as an early warning system to identify hotspots and target localised public health responses, such as increased individual testing and the provision of health warnings.

Abstract
Knowledge about the detection potential and detection rates of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in various body fluids and sites is important for dentists since they, directly or indirectly, deal with many of these fluids/sites in their daily practices. In this study, we attempt to review the latest evidence and meta-analysis studies regarding the detection rate of SARS-CoV-2 in different body specimens and sites as well as the characteristics of these sample. The presence/detection of SARS-CoV-2 viral biomolecules (nucleic acid, antigens, antibody) in different clinical specimens depends greatly on the specimen type and timing of collection. These specimens/sites include nasopharynx, oropharynx, nose, saliva, sputum, bronchoalveolar lavage, stool, urine, ocular fluid, serum, plasma and whole blood. The relative detection rate of SARS-CoV-2 viral biomolecules in each of these specimens/sites is reviewed in detail within the text. The infectious potential of these specimens depends mainly on the time of specimen collection and the presence of live replicating viral particles.

Abstract
Since 2003, coronaviruses have caused multiple global pandemic diseases, including severe acute respiratory syndrome (SARS), Middle East respiratory syndrome (MERS) and coronavirus disease 2019 (COVID-19). Clinical and autopsy findings suggest that the occurrence of kidney injury during infection may negatively affect the clinical outcomes of infected patients. The authoritative model predicts that outbreaks of other novel coronavirus pneumonias will continue to threaten human health in the future. The aim of the present systematic review was to summarize the basic knowledge of coronavirus, coronavirus infection-associated kidney injury and the corresponding therapies, in order to provide new insights for clinicians to better understand the kidney involvement of coronavirus so that more effective therapeutic strategies can be employed against coronavirus infection in the future.

COVID-19 may affect male fertility but is not sexually transmitted: a systematic review. ACTA ACUST UNITED AC 2021; 2:140-149.

Abstract
Objective To determine if SARS-CoV-2, which has led to the rapidly spreading COVID-19 global pandemic, is sexually transmitted. Since the putative receptor for the virus is identified in reproductive organs, it is also important to examine if COVID-19 may affect human fertility. Evidence Review A systematic review of English publications was conducted up to December 11, 2020 in PubMed, NIH iCite COVID-19 portfolio, Cochrane Library, and Google Scholar databases, searching for SARS-CoV-2 in the testes; seminal, prostatic, and vaginal fluids; and cervical smears. A total of 1,997 records were identified, duplicates were removed, and 1,490 records were reviewed for eligibility by examining titles and abstracts. Subsequently, 202 full-text relevant articles were reviewed by 2 independent reviewers. Forty-seven studies (literature reviews, editorials, and guidelines) were assessed qualitatively, and 23 studies that tested the male and female reproductive tracts of patients with COVID-19 for SARS-CoV-2 were quantitatively analyzed. Results No epidemiological investigations to date have described evidence suggesting that COVID-19 is an STD. While angiotensin-converting enzyme 2 receptor is found in the reproductive organs, the lack of co-expression of the TMPRSS2 modulatory protein, required for SARS-CoV-2 cell entry, in testicular cells, sperm, or oocytes, argues against the hypothesis that gametes transmit SARS-CoV-2. Molecular detection studies of SARS-CoV-2 RNA in the male and female reproductive tracts were summarized: 98.0% (293/299) of the seminal fluids, 16/17 testicular biopsies, all 89 prostatic fluids, 98.3% (57/58) of the vaginal fluids, all 35 cervical smears, and all 16 oocyte samples tested negative for SARS-CoV-2. None of the studies confirmed sexual transmission of SARS-CoV-2. Nonetheless, COVID-19 may have detrimental effects on male reproduction by inducing orchitis and/or decreasing testosterone levels, sperm counts, and motility. Conclusion On the basis of the current worldwide published information, COVID-19 is not an STD. This information is important for clinicians, proposed guidelines for public health, U.S. Food and Drug Administration guidelines for gamete and tissue donor eligibility, and fertility treatments. Universal precautions, currently practiced worldwide, are adequate and sufficient at this time to prevent the transmission of known or unknown viral infections. We suggest that recovered patients of COVID-19, especially those with infertility, should be evaluated for their ovarian and testicular function.

COVID-19 a systemic inflammation involving multiple organs, affecting all age groups, with high mortality rate, severe adverse outcomes, and high economic burden need to be described. A systematic review of systematic reviews conducted. We searched PubMed, OVID Medline, Cochrane library, COVID-19 resource centers of N Engl. J Med, AHA, and LITCOVID. Certainty of evidences was evaluated by GRADE approach. Meta-analysis according to random effects model was conducted. Seventy-one eligible systematic reviews are included in the study. A total of 86.5% of them had high quality, and 13.5% had medium quality. Meta-analysis results are presented in tabular format, and the remaining results are presented in narration fashion. COVID-19 involves blood vessels, lung, heart, nervous system, liver, gastrointestinal system, kidney, eyes, and other organs and infects adult and children, neonates, pregnant women, and elderly, transmitted via air born and droplet. Comorbidities associated with COVID-19 are HTN 20.7%, CVD 9.6%, DM 9.55%, respiratory diseases 7%, and 9% of cigarette smoking. Prognostic factors for mortality among COVID-19 cases are acute cardiac injury, diagnosed CVD, DM, respiratory disease, and HTN. Prognostic factors for disease severity are CVD and HTN. Prognostic factors for disease progression were fever, shortness of breath, and smoking. There is no specific antiviral treatment. Preventive measures including physical distancing of 2 m and more, using PPE, avoiding social gatherings, quarantine, and isolation have been recommended. Encouraging telemedicine, online training, and homeschooling are highly recommended. Vaccine is approaching, and concerns exist about vaccine with a high efficacy. Modification of CVD and cardiometabolic risk became the cornerstone for sustainable control of pandemic.

Abstract
Background We describe the incidental detection of patients infiltrates due to COVID-19 in lung basal sections in patients undergoing abdominal computed tomography (CT) with flank pain attending the urology outpatient clinic during the current pandemic. Methods We retrospectively analysed 276 patients admitted to the Siirt Training and Research Hospital Urology outpatients clinic between 15 March 2020 and 9 August 2020 with a complaint of flank pain and undergoing non-contrast abdominal CT. A total of 10 patients with COVID-19 compatible findings in CT were defined as the study group. A control group was formed from 10 patients with only urological pathologies (kidney stones, ureteral stones, and hydronephrosis) without a COVID-19 compatible appearance on CT. Results Ten (3.6 %) patients were identified with COVID-19 and pneumonic infiltrations in the basal regions of the lungs; diagnosis was made by cross-sectional abdominal CT. The visual analog scale (VAS) score of flank pain was significantly higher in the control group (p<0.001); these subjects had urological pathology and no evidence of COVID-19 in the basal regions of the lungs on abdominal CT. There were no signs of COVID-19 disease detected during the admissions procedure in the urology outpatient clinic, including fever, cough, and shortness of breath. Conclusion During the COVID-19 pandemic, it is important to consider a diagnosis of COVID_19 in patients reporting non-severe flank pain if no urological pathology is evident on abdominal CT scans.

Abstract
PURPOSE To review the existing available information regarding urolithiasis management and the impact of COVID-19 on this, and propose recommendations for management of emergency urolithiasis presentations in the COVID-19 era. METHODS Review of published guidelines produced by Urological Governing Bodies, followed by the literature review regarding urolithiasis management during the COVID-19 pandemic. RESULTS Consistent recommendations across guidelines and literature were that urolithiasis with concurrent sepsis or renal failure remains a urological emergency warranting urgent intervention within the pandemic environment. Ureteric stenting and percutaneous nephrostomy are considered equivalent for decompression in this setting, with both ideally to be performed under local anaesthesia where possible to spare ventilators and reduce aerosol-generating procedures. Greater utilization of medical expulsive therapy and dissolution chemolysis may occur during the pandemic, and longer indwelling stent times may be accepted while definite stone clearance is deferred. CONCLUSIONS Urolithiasis will continue to be a source of emergency presentations requiring urgent intervention during the COVID-19 pandemic. However, it is possible to limit these interventions to decompression of the collecting system in the setting of concurrent obstruction or infection, performed under local anaesthesia to limit use of resources and minimise aerosol-generating procedures, with deferral of definitive management.

Abstract
Analysing wastewater can be used to track infectious disease agents that are shed via stool and urine. Sewage surveillance of SARS-CoV-2 has been suggested as a tool to determine the extent of COVID-19 in cities and serve as an early warning for (re-)emergence of SARS-CoV-2 circulation in communities. The focus of this review is on the strength of evidence, opportunities and challenges for the application of sewage surveillance to inform public health decision making. Considerations for undertaking sampling programs are reviewed including sampling sites, strategies, sample transport, storage and quantification methods; together with the approach and evidence base for quantifying prevalence of infection from measured wastewater concentration. Published SARS-CoV-2 sewage surveillance studies (11 peer reviewed and 10 preprints) were reviewed to demonstrate the current status of implementation to support public health decisions. Although being very promising, a number of areas were identified requiring additional research to further strengthen this approach and take full advantage of its potential. In particular, design of adequate sampling strategies, spatial and temporal resolution of sampling, sample storage, replicate sampling and analysis, controls for the molecular methods used for the quantification of SARS-CoV-2 RNA in wastewater. The use of appropriate prevalence data and methods to correlate or even translate SARS-CoV-2 concentrations in wastewater to prevalence of virus shedders in the population is discussed.

Abstract
The coronavirus disease 2019 (COVID-19) pandemic is still spreading worldwide, affecting several million people. Unlike the previous two coronavirus outbreaks, COVID-19 has caused several thousand deaths for respiratory and multiple organ failure. As specifically concerns this latest infectious pathology, laboratory medicine can provide a substantial contribution to diagnosing an acute severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection through molecular testing, establishing the presence and extent of an immune response against the virus, mostly through serological testing. However, it can also help to predict the risk of unfavorable disease progression by measuring some conventional laboratory tests and, last but not least, can provide reliable therapeutic guidance. This article is hence aimed at offering recent updates on the important role and value of laboratory investigations in COVID-19, also providing information on some hot topics such as virus RNA detection in different biological samples, causes of recurrent positivity of reverse-transcription polymerase chain reaction (RT-PCR), potential strategies for enhancing the throughput of molecular testing (i.e., pre-test probability assessment, sample pooling, use of rapid tests), as well as pragmatic indications for enhancing the quality and value of serological testing and laboratory-based monitoring.

Abstract
Purpose To determine how members of the Société Internationale d’Urologie (SIU) are continuing their education in the time of COVID-19. Methods A survey was disseminated amongst SIU members worldwide by email. Results were analyzed to examine the influence of age, practice region and settings on continuing medical education (CME) of the respondents. Results In total, 2494 respondents completed the survey. Internet searching was the most common method of CME (76%; all ps < 0.001), followed by searching journals and textbook including the online versions (62%; all ps < 0.001). Overall, 6% of the respondents reported no time/interest for CME during the pandemic. Although most urologists report using only one platform for their CME (26.6%), the majority reported using ≥ 2 platforms, with approximately 10% of the respondents using up to 5 different platforms. Urologists < 40 years old were more likely to use online literature (69%), podcasts/AV media (38%), online CME courses/webinars (40%), and social media (39%). There were regional variations in the CME modality used but no significant difference in the number of methods by region. There was no significant difference in responses between urologists in academic/public hospitals or private practice. Conclusion During COVID-19, urologists have used web-based learning for their CME. Internet learning and literature were the top frequently cited learning methods. Younger urologists are more likely to use all forms of digital learning methods, while older urologists prefer fewer methods.
