BACKGROUND Available scientific evidence of transcatheter mitral valve repair with the MitraClip comes from randomized controlled trials, which showed controversial results that hardly translate into real-world practice, and from registries of relatively small sample size. AIM To collect real-world data in a multicenter, prospective, country-level registry. METHODS AND RESULT The Italian Society of Interventional Cardiology (GIse) Registry Of Transcatheter Treatment of Mitral Valve RegurgitaTiOn (GIOTTO) is an ongoing single-arm, multicenter, prospective registry that started enrollment in February 2016. Clinical end points were defined according to the Mitral Valve Academic Research Consortium (MVARC) criteria. From February 2016 to December 2018, 1189 patients (mean age 76 ± 9.1 years) were enrolled. The main MR etiology was functional (64.9%). MVARC technical success was 96.6%. At 30-day follow-up (n = 1131), MVARC device and procedural success were 92.5% and 87% respectively, and all-cause death was 3%. The majority of patients who died at 30-day had functional MR (69.7%). Mixed etiology (OR 0.94, 95% CI 0.02-0.61) and prolonged length of stay in ICU (OR 0.97, 95% CI 0.95-0.99) were found to be negative independent predictors of device success at 30-day. The EuroSCORE II (OR 0.96, 95% CI 0.93-0.99), LVEDV-I (OR 0.99, 95% CI 0.98-0.99) and prolonged length of stay in ICU (OR 0.98, 95% CI 0.97-0.99) were negative independent factors of MVARC procedural success at 30-day. CONCLUSIONS The GIOTTO registry is one of the largest prospective registries available on MitraClip and shows favorable acute and 30-day safety and efficacy. RATIONALE AND OBJECTIVES The purpose of this study is to quantify breast radiologists' performance at predicting occult invasive disease when ductal carcinoma in situ (DCIS) presents as calcifications on mammography and to identify imaging and histopathological features that are associated with radiologists' performance. MATERIALS AND METHODS Mammographically detected calcifications that were initially diagnosed as DCIS on core biopsy and underwent definitive surgical excision between 2010 and 2015 were identified. https://www.selleckchem.com/products/ca-170.html Thirty cases of suspicious calcifications upstaged to invasive ductal carcinoma and 120 cases of DCIS confirmed at the time of definitive surgery were randomly selected. Nuclear grade, estrogen and progesterone receptor status, patient age, calcification long axis length, and breast density were collected. Ten breast radiologists who were blinded to all clinical and pathology data independently reviewed all cases and estimated the likelihood that the DCIS would be upstaged to invasive disease at surgical excision. Subgroup analysis was performed based on nuclear grade, long axis length, breast density and after exclusion of microinvasive disease. RESULTS Reader performance to predict upstaging ranged from an area under the receiver operating characteristic curve (AUC) of 0.541-0.684 with a mean AUC of 0.620 (95%CI 0.489-0.751). Performances improved for lesions smaller than 2 cm (AUC 0.676 vs 0.500; p = 0.002). The exclusion of microinvasive cases also improved performance (AUC 0.651 vs 0.620; p = 0.005). There was no difference in performance based on breast density (p = 0.850) or nuclear grade (p = 0.270) CONCLUSION Radiologists were able to predict invasive disease better than chance, particularly for smaller DCIS lesions ( less then 2 cm) and after the exclusion of microinvasive disease. Abdominal hernias are a frequent complication in peritoneal dialysis, representing up to 60.4% of anatomical complications. Their prevalence varies between 7 and 27.5%. Established risk factors are male gender, an older age, multiparity, a low body mass index and a paramedian approach for the catheter insertion. Polykystic renal disease and the intra-peritoneal volume are controversial risk factors. The diagnosis is mainly clinical, though peritoneography imaging can be useful in difficult cases. Hernia's complications, of strangulation, incarceration, bowel occlusion and peritonitis; can be very serious, leading to technique failure and may result in death. The complication risk varies from 4 to 20% in the literature review. There are no guidelines regarding hernia's prevention or treatment. A surgical repair is recommended, by implementing a synthetic prothesis with an inguinal approach for inguinal and femoral hernias, with a simple stitch or a bioprothesis for ombilical hernias. The management of peritoneal dialysis after hernia repair is not codified. After an initial 48h interruption, an intermittent peritoneal dialysis program using low volume seems efficient at low risk, preventing a temporary transfer to haemodialysis. RESEARCH QUESTION Polycystic ovary syndrome (PCOS) is a complex endocrine disorder with diverse clinical implications, such as infertility, metabolic disorders, cardiovascular diseases and psychological problems among others. The heterogeneity of conditions found in PCOS contribute to its various phenotypes, leading to difficulties in identifying proteins involved in this abnormality. Several studies, however, have shown the feasibility in identifying molecular evidence underlying other diseases using graph cluster analysis. Therefore, is it possible to identify proteins and pathways related to PCOS using the same approach? METHODS Known PCOS-related proteins (PCOSrp) from PCOSBase and DisGeNET were integrated with protein-protein interactions (PPI) information from Human Integrated Protein-Protein Interaction reference to construct a PCOS PPI network. The network was clustered with DPClusO algorithm to generate clusters, which were evaluated using Fisher's exact test. Pathway enrichment analysis using gProfileR was conducted to identify significant pathways. RESULTS The statistical significance of the identified clusters has successfully predicted 138 novel PCOSrp with 61.5% reliability and, based on Cronbach's alpha, this prediction is acceptable. Androgen signalling pathway and leptin signalling pathway were among the significant PCOS-related pathways corroborating the information obtained from the clinical observation, where androgen signalling pathway is responsible in producing male hormones in women with PCOS, whereas leptin signalling pathway is involved in insulin sensitivity. CONCLUSIONS These results show that graph cluster analysis can provide additional insight into the pathobiology of PCOS, as the pathways identified as statistically significant correspond to earlier biological studies. Therefore, integrative analysis can reveal unknown mechanisms, which may enable the development of accurate diagnosis and effective treatment in PCOS.
