Peri-operative SARS-CoV-2 infection increases postoperative mortality. The aim of this study was to determine the optimal duration of planned delay before surgery in patients who have had SARS-CoV-2 infection. This international, multicentre, prospective cohort study included patients undergoing elective or emergency surgery during October 2020. Surgical patients with pre-operative SARS-CoV-2 infection were compared with those without previous SARS-CoV-2 infection. The primary outcome measure was 30-day postoperative mortality. Logistic regression models were used to calculate adjusted 30-day mortality rates stratified by time from diagnosis of SARS-CoV-2 infection to surgery. Among 140,231 patients (116 countries), 3127 patients (2.2%) had a pre-operative SARS-CoV-2 diagnosis. Adjusted 30-day mortality in patients without SARS-CoV-2 infection was 1.5% (95%CI 1.4-1.5). In patients with a pre-operative SARS-CoV-2 diagnosis, mortality was increased in patients having surgery within 0-2 weeks, 3-4 weeks and 5-6 weeks of the diagnosis (odds ratio (95%CI) 4.1 (3.3-4.8), 3.9 (2.6-5.1) and 3.6 (2.0-5.2), respectively). Surgery performed ≥ 7 weeks after SARS-CoV-2 diagnosis was associated with a similar mortality risk to baseline (odds ratio (95%CI) 1.5 (0.9-2.1)). After a ≥ 7 week delay in undertaking surgery following SARS-CoV-2 infection, patients with ongoing symptoms had a higher mortality than patients whose symptoms had resolved or who had been asymptomatic (6.0% (95%CI 3.2-8.7) vs. 2.4% (95%CI 1.4-3.4) vs. 1.3% (95%CI 0.6-2.0), respectively). Where possible, surgery should be delayed for at least 7 weeks following SARS-CoV-2 infection. Patients with ongoing symptoms ≥ 7 weeks from diagnosis may benefit from further delay.

Inflammation is inherent in prostatic diseases and it is now accepted that it may facilitate cellular proliferation in both benign and malignant conditions. The strong relationship between prostatic inflammation and pathogenesis of benign prostatic hyperplasia (BPH) is supported by epidemiologic, histopathologic and molecular evidence. Contrariwise, the role of inflammation in prostate carcinogenesis is still controversial, although current data indicate that the inflammatory microenvironment can regulate prostate cancer (PCa) growth and progression. Knowledge of the complex molecular landscape associated with chronic inflammation in the context of PCa may lead to the introduction and optimization of novel targeted therapies. In this perspective, evaluation of the inflammatory component in prostate specimens could be included in routine pathology reports.

SARS-CoV-2 has been associated with an increased rate of venous thromboembolism in critically ill patients. Since surgical patients are already at higher risk of venous thromboembolism than general populations, this study aimed to determine if patients with peri-operative or prior SARS-CoV-2 were at further increased risk of venous thromboembolism. We conducted a planned sub-study and analysis from an international, multicentre, prospective cohort study of elective and emergency patients undergoing surgery during October 2020. Patients from all surgical specialties were included. The primary outcome measure was venous thromboembolism (pulmonary embolism or deep vein thrombosis) within 30 days of surgery. SARS-CoV-2 diagnosis was defined as peri-operative (7 days before to 30 days after surgery); recent (1-6 weeks before surgery); previous (≥7 weeks before surgery); or none. Information on prophylaxis regimens or pre-operative anti-coagulation for baseline comorbidities was not available. Postoperative venous thromboembolism rate was 0.5% (666/123,591) in patients without SARS-CoV-2; 2.2% (50/2317) in patients with peri-operative SARS-CoV-2; 1.6% (15/953) in patients with recent SARS-CoV-2; and 1.0% (11/1148) in patients with previous SARS-CoV-2. After adjustment for confounding factors, patients with peri-operative (adjusted odds ratio 1.5 (95%CI 1.1-2.0)) and recent SARS-CoV-2 (1.9 (95%CI 1.2-3.3)) remained at higher risk of venous thromboembolism, with a borderline finding in previous SARS-CoV-2 (1.7 (95%CI 0.9-3.0)). Overall, venous thromboembolism was independently associated with 30-day mortality ). In patients with SARS-CoV-2, mortality without venous thromboembolism was 7.4% (319/4342) and with venous thromboembolism was 40.8% (31/76). Patients undergoing surgery with peri-operative or recent SARS-CoV-2 appear to be at increased risk of postoperative venous thromboembolism compared with patients with no history of SARS-CoV-2 infection. Optimal venous thromboembolism prophylaxis and treatment are unknown in this cohort of patients, and these data should be interpreted accordingly.

Purpose: The study aims to investigate the potential associations between preoperative plasma levels of total testosterone (TT) and biopsy Gleason score (bGS) upgrading in prostate cancer (PCA) patients undergoing radical prostatectomy (RP). Materials and Methods: Exclusion criteria were treatment with 5α-reductase inhibitors, LH-releasing hormone analogues or testosterone replacement. Criteria of bGS upgrading were as follows: (i) bGS 6 to pathological Gleason score (pGS) >6, (ii) bGS 7 with pattern 3 + 4 to pGS 7 with pattern 4 + 3 or to pGS >7, (iii) bGS 7 with pattern 4 + 3 to pGS >7. Patients who showed bGS >7 were excluded from the cohort. Results: The study included 209 patients. Tumor upgrading was assessed in 76 (36.4%) cases of the entire cohort, in 51 out of 130 cases (39.2%) of the bGS 6 group and 25 out of 79 patients (31.6%) in the bGS 7 cluster. Logistic regression models showed that independent clinical covariates predicting the risk of bGS upgrading included TT (OR 1.058; p = 0.027) and prostate-specific antigen (PSA) density (OR 23.3; p = 0.008) as well as TT (OR 1.057; p = 0.029) with PSA (OR 1.061; p = 0.023). The model suggests that 1 unit increase in TT plasma levels increases the odds of bGS upgrading by 5.8 or 5.7%. Conclusions: In summary, we have determined that high TT preoperative plasma levels independently predict bGS upgrading in men with PCA undergoing RP. Preoperative plasma levels of TT might be included as a potential marker for assessing the risk bGS upgrading.

Objective: To identify clinical factors associated with prostate cancer (PCA) upgrading to higher patterns of the surgical specimen in low-risk PCA. Materials and Methods: We evaluated the records of 438 patients. The multinomial logistic regression model was used. Results: Low-risk PCA included 170 cases (38.8%) and tumor upgrading was detected in 111 patients (65.3%) of whom 72 (42.4%) had pathological Gleason patterns (pGP) = 3 + 4 and 39 (22.9%) pGP >3 + 4. Prostate-specific antigen (PSA) and proportion of positive cores (P+) were independent predictors of tumor upgrading to higher patterns. The main difference between upgraded cancers related to PSA and to P+ >0.20. The population was stratified into risk classes by PSA ≤5 μg/l and P+ ≤0.20 (class A), PSA >5 μg/l and P+ ≤0.20 (class B), PSA ≤5 μg/l and P+ >0.20 (class C) and PSA >5 μg/l and P+ 0.20 (class D). Upgrading rates to pGP >3 + 4 were extremely low in class A (5.1%), extremely high in D (53.8%). Conclusions: Low-risk PCA is a heterogeneous population with significant rates of undetected high-grade disease. Significant clinical predictors of upgrading to higher patterns include PSA and P+, which identify a very high-risk class that needs repeat biopsies in order to reclassify tumor grade.

Urinary Tract Infections (UTIs) are amongst the most common infectious diseases and carry a significant impact on patient quality of life and health care costs. Despite that, there is no well-established recommendation for a "standard" prophylactic antibiotic management to prevent UTI recurrences. The majority of patients undergoes long-term antibiotic treatment that severely impairs the normal microbiota and increases the risk of development of multidrugresistant microorganisms. In this scenario, the use of phytotherapy to both alleviate symptoms related to UTI and decrease the rate of symptomatic recurrences is an attractive alternative. Several recently published papers report conflicting findings and cannot give confident recommendations for the everyday clinical practice. A new approach to the management of patients with recurrent UTI might be to use nutraceuticals or phytotherapy after an accurate assessment of the patient`s risk factors. No single compound or mixture has been identified so far as the best preventive approach in patients with recurrent UTI. We reviewed our non-antibiotic approach to the management of recurrent UTI patients in order to clarify the evidence-base for the commonly used substances, understand their pharmacokinetics and pharmacodynamics in order to tailor the best way to improve patient's quality of life and reduce the rate of antibiotic resistance. Lack of a gold-standard recommendation and the risk of increasing antibiotic resistance is the reason why we need alternatives to antibiotics in the management of urinary tract infections (UTIs). A tailored approach according to bacterial characteristics and the patient risk factors profile is a promising option.KEY WORDS: Nutraceuticals; Phytotherapy; Urinary tract infections.Submitted 13 January 2017; Accepted 28 January 2017 SummaryNo conflict of interest declared.

Objectives: To evaluate clinical predictors of disease reclassification or progression (DR/P) in prostate cancer patients elected to active surveillance (AS). Material and Methods: Patients were assessed on the basis of DR/P criteria. Predictors of DR/P were evaluated by multivariate logistic regression and Cox proportional hazards. Results: The median DR/P free time was 16.5 months. DR/P was detected in 30 out of 84 cases (35.7%). In DR/P cases, the median prostate volume (PV) was significantly lower (34.7 vs. 42.7 ml) and the percentage of cases with 2 or 3 vs. 1 initial biopsy positive cores (BPC) was significantly higher (36.7 vs. 7.4%). The multivariate logistic regression model showed that PV (OR 0.9; p = 0.021) and initial n >1 BPC (OR 9.8; p = 0.001) were independent predictors of DR/P. By Cox multivariate proportional hazards, only n >1 BPC predicted early DR/P (hazard ratio 3.1; p = 0.003). Conclusions: In a contemporary cohort of patients elected to AS, independent factors stratifying the risk of DR/P were PV and initial BPC, which also predicted early DR/P. In patients elected to AS, the identification of risk factors of DR/P require early re-biopsy. Confirmatory studies are required.
