Prostatic calculi detected in peripheral zone of the gland during a transrectal ultrasound biopsy can be significant predictors of prostate cancer

Purpose: Prostatic calculi (PC) are usually associated with benign prostatic hyperplasia or chronic inflammation. However, in several studies prostatic inflammation and calcification have been implicated in the pathogenesis of prostate cancer (CaP). We evaluated the prevalence of PC during transrectal ultrasound (TRUS) and correlate the ultrasonographic patterns with histological findings. Methods: A prospective study of 664 patients undergoing TRUS and prostate biopsy was planned. A standardized reproducible technique was used with using a GE Logiq 7 machine equipped with a 5-9MHz multi-frequency convex probe "end-fire". We defined marked presence of PC as multiple hyperechoic foci with significant area (≥ 3 mm in the largest diameter). PC were classified according to zone distribution into the gland: transitional zone (TZ), central zone (CZ), and peripheral zone (PZ). Results: No significant difference was noted between the patients with PC and without PC, when comparing age, preoperative PSA level, prostate volume, and biopsy number, except for DRE findings. 168 patients (25.3%) had marked presence of PC on TRUS: 50.6% in TZ, 20.2% in CZ, and 29.2% in PZ. 31 patients (63.3%) with presence of PC in PZ had CaP on biopsy. The correlation observed between CaP and the presence of PC in PZ was statistically significant (p < 0.001). However, among patients in the CaP group there was no statistical association between PC and moderate or high Gleason grade. Conclusions: This study suggests that chronic prostatic inflammation and PC have a role in the biogenesis of cancer. CaP was more frequent in patients with PC in PZ of the gland, but was not associated with higher Gleason grade among these patients (p < 0.001)

The Bronze and Iron Age habitation on Timpone della Motta in the light of recent research

This paper presents material evidence for a continuous sequence of inhabitation of the archaeological site of Timpone della Motta at present-day Francavilla Marittima (northern Calabria) from the Middle Bronze Age 2 (MBA2) to the end of the Archaic period (ca. 1700 BC – 500 BC). The authors bring together results of investigations at eight different locations of the Timpone della Motta ranging in location from the summit of the site down to its lower slopes. Importantly, the new evidence sheds light on the transition from the late Bronze Age to early Iron Age phases, which, while characterized by continuity in hut dwellings, sees the introduction of Greek-inspired pottery wares, shapes and decorations in household and production contexts. On a regional level, the compiled evidence now securely places the Timpone della Motta among the major protohistoric settlements that sprung up in the MBA2 in the foothills lining the plain of Sybaris prior to its transformation during the late Iron Age and Archaic periods in an indigenous and then Greek sanctuary. Notably, already before the Greek colonial period, in the course of the 8th c. BC, the Timpone della Motta shows evidence for a well-established Aegean connection on the evidence of Euboean pottery and before that in the Middle and Recent Bronze Age (MBA-RBA) judging from the presence of recently identified (Italo-) Mycenean potsherd

Management of the pelvic floor disfunctions: combined versus single surgical procedure in a multidisciplinary approach: a retrospective study

The objective of this study was to compare the outcome of combined surgical treatment of multicompartmental pelvic floor defects versus single procedures within a multidisciplinary path in order to try to clarify what is the most effective surgical approach

Serum Albumin Is Inversely Associated With Portal Vein Thrombosis in Cirrhosis

We analyzed whether serum albumin is independently associated with portal vein thrombosis (PVT) in liver cirrhosis (LC) and if a biologic plausibility exists. This study was divided into three parts. In part 1 (retrospective analysis), 753 consecutive patients with LC with ultrasound-detected PVT were retrospectively analyzed. In part 2, 112 patients with LC and 56 matched controls were entered in the cross-sectional study. In part 3, 5 patients with cirrhosis were entered in the in vivo study and 4 healthy subjects (HSs) were entered in the in vitro study to explore if albumin may affect platelet activation by modulating oxidative stress. In the 753 patients with LC, the prevalence of PVT was 16.7%; logistic analysis showed that only age (odds ratio [OR], 1.024; P = 0.012) and serum albumin (OR, -0.422; P = 0.0001) significantly predicted patients with PVT. Analyzing the 112 patients with LC and controls, soluble clusters of differentiation (CD)40-ligand (P = 0.0238), soluble Nox2-derived peptide (sNox2-dp; P < 0.0001), and urinary excretion of isoprostanes (P = 0.0078) were higher in patients with LC. In LC, albumin was correlated with sCD4OL (Spearman's rank correlation coefficient [r(s)], -0.33; P < 0.001), sNox2-dp (r(s), -0.57; P < 0.0001), and urinary excretion of isoprostanes (r(s), -0.48; P < 0.0001) levels. The in vivo study showed a progressive decrease in platelet aggregation, sNox2-dp, and urinary 8-iso prostaglandin F2 alpha-III formation 2 hours and 3 days after albumin infusion. Finally, platelet aggregation, sNox2-dp, and isoprostane formation significantly decreased in platelets from HSs incubated with scalar concentrations of albumin. Conclusion: Low serum albumin in LC is associated with PVT, suggesting that albumin could be a modulator of the hemostatic system through interference with mechanisms regulating platelet activation

Colorectal Cancer Stage at Diagnosis Before vs During the COVID-19 Pandemic in Italy

IMPORTANCE Delays in screening programs and the reluctance of patients to seek medical attention because of the outbreak of SARS-CoV-2 could be associated with the risk of more advanced colorectal cancers at diagnosis. OBJECTIVE To evaluate whether the SARS-CoV-2 pandemic was associated with more advanced oncologic stage and change in clinical presentation for patients with colorectal cancer. DESIGN, SETTING, AND PARTICIPANTS This retrospective, multicenter cohort study included all 17 938 adult patients who underwent surgery for colorectal cancer from March 1, 2020, to December 31, 2021 (pandemic period), and from January 1, 2018, to February 29, 2020 (prepandemic period), in 81 participating centers in Italy, including tertiary centers and community hospitals. Follow-up was 30 days from surgery. EXPOSURES Any type of surgical procedure for colorectal cancer, including explorative surgery, palliative procedures, and atypical or segmental resections. MAIN OUTCOMES AND MEASURES The primary outcome was advanced stage of colorectal cancer at diagnosis. Secondary outcomes were distant metastasis, T4 stage, aggressive biology (defined as cancer with at least 1 of the following characteristics: signet ring cells, mucinous tumor, budding, lymphovascular invasion, perineural invasion, and lymphangitis), stenotic lesion, emergency surgery, and palliative surgery. The independent association between the pandemic period and the outcomes was assessed using multivariate random-effects logistic regression, with hospital as the cluster variable. RESULTS A total of 17 938 patients (10 007 men [55.8%]; mean [SD] age, 70.6 [12.2] years) underwent surgery for colorectal cancer: 7796 (43.5%) during the pandemic period and 10 142 (56.5%) during the prepandemic period. Logistic regression indicated that the pandemic period was significantly associated with an increased rate of advanced-stage colorectal cancer (odds ratio [OR], 1.07; 95%CI, 1.01-1.13; P = .03), aggressive biology (OR, 1.32; 95%CI, 1.15-1.53; P < .001), and stenotic lesions (OR, 1.15; 95%CI, 1.01-1.31; P = .03). CONCLUSIONS AND RELEVANCE This cohort study suggests a significant association between the SARS-CoV-2 pandemic and the risk of a more advanced oncologic stage at diagnosis among patients undergoing surgery for colorectal cancer and might indicate a potential reduction of survival for these patients
