Evaluation of the long-term efficacy and safety of an imidacloprid 10%/flumethrin 4.5% polymer matrix collar (Seresto®) in dogs and cats naturally infested with fleas and/or ticks in multicentre clinical field studies in Europe

<p>Abstract</p> <p>Background</p> <p>The objective of these two GCP multicentre European clinical field studies was to evaluate the long-term efficacy and safety of a new imidacloprid/flumethrin collar (Seresto^®, Bayer AnimalHealth, Investigational Veterinary Product(IVP)) in dogs and cats naturally infested with fleas and/or ticks in comparison to a dimpylat collar ("Ungezieferband fuer Hunde/fuer Katzen", Beaphar, Control Product (CP)).</p> <p>Methods</p> <p>232 (IVP) and 81 (CP) cats and 271(IVP) and 129 (CP) dogs were treated with either product according to label claims and formed the safety population. Flea and tick counts were conducted in monthly intervals for up to 8 months in the efficacy subpopulation consisting of 118 (IVP) + 47 (CP) cats and 197 (IVP) + 94 (CP) dogs. Efficacy was calculated as reduction of infestation rate within the same treatment group and statistically compared between the two treatment groups.</p> <p>Results</p> <p>Preventive efficacy against fleas in cats/dogs varied in the IVP group between 97.4%/94.1% and 100%/100% (overall mean: 98.3%/96.7%) throughout the 8 month period and in the CP group between 57.1%/28.2% and 96.1%/67.8% (overall mean: 79.3%/57.9%). Preventive efficacy against ticks in cats/dogs varied in the IVP group between 94.0%/91.2% and 100%/100% (overall mean: 98.4%/94.7%) throughout the 8 month period and in the CP group between 90.7%/79.9% and 100%/88.0% (overall mean: 96.9%/85.6%). The IVP group was statistically non-inferior to the CP group, and on various assessment days, statistical superiority was proven for flea and tick count reduction in dogs and cats. Both treatments proved to be safe in dogs and cats with mainly minor local observations at the application site. There was moreover, no incidence of any mechanical problem with the collar in dogs and cats during the entire study period.</p> <p>Conclusions</p> <p>The imidacloprid/flumethrin collar proved to reduce tick counts by at least 90% and flea counts by at least 95% for a period of at least 7-8 months in cats and dogs under field conditions. Therefore, it can be used as sustainable long-term preventative, covering the whole flea and tick season.</p

Can we predict the need for clean intermittent catheterization after orthotopic neobladder construction?

Introduction: We aimed to identify peri-operative and pathologic characteristics that may predict the need for clean intermittent catheterization (CIC) following radical cystectomy (RC) with orthotopic neobladder (ONB) in order to improve patient counseling on choice of urinary diversion. Materials and Methods: Between July 2004 and February 2013, all patients who underwent RC with ONB were identified. Peri-operative clinical and pathological features were evaluated and correlated with patients reported need for CIC. The independent T-test was performed for continuous variables and Chi-square test was performed for categorical variables. Multivariate forward stepwise logistic regression analysis was used to identify variables that correlated with need for CIC after ONB. Results: During the study period, 114 patients underwent RC with ONB creation. On univariate analysis, patients with higher body mass index, younger age, and non-vaginal or non-nerve-sparing procedures were more likely to require catheterization for complete emptying. Multivariate analysis demonstrates that conservative surgery (nerve sparing in males or vaginal sparing in females) was associated with a significantly lower rate of requiring CIC (Odds Ratio [OR] 0.20, P < 0.01). Surprisingly, older age was also associated with a slightly lower, but statistically significant, rate of requiring CIC (OR 0.92,P < 0.01). Conclusions: When counseling patients regarding the different types of diversions after RC, the potential need for long-term CIC after ONB must be discussed. The clinical factors that appear to increase the need for CIC include non-conservative RC (non-nerve sparing in males and non-vaginal sparing in females) and, to a certain degree, younger age

Two-Year Outcomes After Aquablation Compared to TURP: Efficacy and Ejaculatory Improvements Sustained

INTRODUCTION: To compare 2-year safety and efficacy outcomes after Aquablation or transurethral resection of the prostate (TURP) for the treatment of lower urinary tract symptoms related to benign prostate hyperplasia (BPH). METHODS: One hundred eighty-one patients with BPH were assigned at random (2:1 ratio) to either Aquablation or TURP. Patients and follow-up assessors were blinded to treatment. Assessments included the International Prostate Symptom Score (IPSS), Male Sexual Health Questionnaire (MSHQ), International Index of Erectile Function and uroflow. The focus of analysis was 2-year outcomes. RESULTS: At 2 years, IPSS scores improved by 14.7 points in the Aquablation group and 14.9 points in TURP (p = .8304, 95% CI for difference - 2.1 to 2.6 points). Two-year improvements in maximum flow rate (Qmax) were large in both groups at 11.2 and 8.6 cc/s for Aquablation and TURP, respectively (p = 0.1880, 95% CI for difference - 1.3 to 6.4). Sexual function as assessed by MSHQ was stable in the Aquablation group and decreased slightly in the TURP group. At 2 years, PSA was reduced significantly in both groups by 0.7 and 1.2 points, respectively; the reduction was similar across groups (p = 0.1816). Surgical retreatment rates after 12 months for Aquablation were 1.7% and 0% for TURP. Over 2 years, surgical BPH retreatment rates were 4.3% and 1.5% (p = 0.4219), respectively. CONCLUSION: Two-year efficacy outcomes after TURP and Aquablation were similar, and the rate of surgical retreatment was low and similar to TURP. TRIAL REGISTRATION: ClinicalTrials.gov no.

Aquablation for Benign Prostatic Hyperplasia in Large Prostates (80-150 cc): 1-Year Results

OBJECTIVE To report 12-month safety and effectiveness outcomes of the Aquablation procedure for the treatment of men with symptomatic benign prostatic hyperplasia (BPH) and large-volume prostates. METHODS One hundred and one men with moderate-to-severe BPH symptoms and prostate volumes of 80-150 cc underwent a robotic-assisted Aquablation procedure in a prospective multicenter international clinical trial. Functional and safety outcomes were assessed at 12 months postoperatively. RESULTS Mean prostate volume was 107 cc (range 80-150). Mean operative time was 37 minutes and mean Aquablation resection time was 8 minutes. The average length of hospital stay following the procedure was 1.6 days. Mean International Prostate Symptom Score improved from 23.2 at baseline to 6.2 at 12 months (P 100 at baseline). Antegrade ejaculation was maintained in 81% of sexually active men. No patient underwent a repeat procedure for BPH symptoms. There was a 2% de novo incontinence rate at 12 months, and 10 patients did require a transfusion postoperatively while 5 required take back fulgurations. At 12 months, prostate-specific antigen reduced from 7.1 ± 5.9 ng/mL at baseline to 4.4 ± 4.3 ng/mL. CONCLUSION The Aquablation procedure is demonstrated to be safe and effective in treating men with large prostates (80-150 cc) after 1 year of follow-up, with an acceptable complication rate and without a significant increase in procedure or resection time compared to smaller sized glands
