OBJECTIVE To characterize penile prosthesis surgery utilization and assess for regional differences in the use of this procedure across the United States. MATERIALS & METHODS We examined penile prosthesis surgeries (inflatable and semi-rigid implants) in Medicare beneficiaries with ED for the years 2006 through 2014. Adjusted utilization rates were calculated per 1000 beneficiaries accounting for age and race. Utilization rates were examined nationally and by hospital referral region (HRR). RESULTS The national adjusted rate of penile prosthesis surgery declined from 5.41 per 1000 beneficiaries in 2006 to 3.74 per 1000 beneficiaries in 2014. click here The number of beneficiaries diagnosed with ED outpaced the number of patients undergoing surgery. Regional variation was observed; a 12-fold difference in 2014 (1.9/1000 in Norfolk, VA to 24.2/1000 in Miami, FL). Adjustment of 2014 data by urology provider density reduced variation between HRRs, and as a result a 3.5-fold difference was observed. Over 60% of HRRs performed zero to less then 11 surgeries. CONCLUSIONS The rate of penile prosthesis surgery is declining amongst Medicare beneficiaries with ED. Significant regional variation exists in the utilization of penile prosthesis surgery. This variation may be explained by a series of urologist and patient-specific factors, including provider density. Penile prosthesis surgery in Medicare beneficiaries is likely highly dependent on where these patients seek care. OBJECTIVE To compare perioperative outcomes between lower, mid, and upper pole access locations for patients undergoing single-access, unilateral PCNL. METHODS We queried our institutional PCNL database to include patients who had unilateral, single access procedures. We excluded patients who had a contralateral procedure during the same admission or multi-access procedures. Patients were grouped by the site of PCNL access (lower, mid, or upper pole). Among groups, we compared post-operative day one (POD1) stone-free rates as measured by abdominal CT scan or plain-film X-ray and consequent need for a secondary procedure. We further compared postoperative complication rates. RESULTS We included 767 patients for analysis, with the majority of access locations being in the lower pole (80.2%). Patients across groups had similar age, body mass index (BMI), and stone laterality. Patients with horseshoe kidneys more commonly had mid or upper pole access compared to lower pole. The percentage of patients with no residual stone fragments seen on POD 1 imaging was similar for lower, mid, and upper pole groups (57.7% vs 65.0% vs 61.6%, respectively; p=0.526). Additionally, we observed no difference in the percentage of patients requiring a secondary procedure among the above groups (33.5% vs 22.5% vs 31.3%, respectively; p=0.337). Patients experienced no difference in complications among groups. CONCLUSIONS When performing unilateral PCNL using a single site of access, we observed no difference in stone-free rates or complications between lower, mid, and upper pole locations. Appropriate selection of access location in PCNL should be individualized to patient factors and surgeon experience. BACKGROUND Parkinson's disease (PD) affects millions of people worldwide, and it is predicted that this pathology will gravely increase in the next few years. Unfortunately, there's currently no cure for this disease, indeed an early diagnosis of Parkinson's disease can help to better manage its symptoms and its evolution. One of the most frequent abilities and usually also the first manifestation of Parkinson's disease is alteration of handwriting. NEW METHOD We propose a novel method to detect Parkinson's disease, based on the segmentation of the online handwritten text into lines. Indeed, we propose to compare Parkinson's disease patients and healthy controls, based on the full dynamics of new temporal and spectral features. Three classifiers were used, K-Nearest Neighbors, Support Vector Machine and Decision Trees. The performances of these three classifiers were estimated using a stratified nested 10 cross-validation. All the models in this study have been evaluated using classification accuracy, balanced accuracy, sensitivity, specificity, F-Score and Matthews Correlation Coefficient. click here RESULTS An accuracy of 92.86 % was obtained with Decision Trees classifier in the last line. The new categories of spectral and temporal features gave the best classification performances in comparison to the basic statistical features. COMPARISON WITH EXISTING METHODS Previous studies have only focused on words or sentences. This is the first study to deal with the analysis of a text composed of several lines. CONCLUSION The last line discriminates at best between Parkinson's disease patients and healthy controls. This obtained result has further strengthened our hypothesis concerning the fatigue occurring while writing in PD patients. BACKGROUND The neuronal ceroid lipofuscinosis 2 (NCL2) or classic late-infantile neuronal ceroid lipofuscinosis (LINCL) is a neurogenetic disorder caused by mutations in the TPPI gene, which codes for the lysosomal tripeptidyl peptidase 1 (TPPI) EC 3.4.14.9. Loss of functional TPPI activity results in progressive visual and neurological symptoms starting at around 1-2 years of age causing early death. METHODS We report a DBS-based TPPI assay that cleaves a synthetic tetrapeptide substrate generating a product that is detected by HPLC. Probands and carriers were identified with 100% accuracy (7 probands, 30 carriers, 13 controls). RESULTS The assay detected a single TPPI activity at a lower pH towards the substrate tested. TPPI activity measurable when extracted at lower pH while inactive at neutral pH showed steady increase for at least 8 h incubation. No loss in TPPI activity was observed when DBS were stored for at least 2 weeks either in freezer, refrigerator, room temperature or 42 °C. CONCLUSION A sequence variant causing Arg339Gln substitution in a proband had 12% TPPI. TPPI activity can be reliably measured in DBS, giving an opportunity to diagnose NCL2 at birth and refer patients for enzyme replacement or other therapies for earliest intervention, or alternatively offers a second-tier confirmatory test.
