Whilst industrial robots have been widely used in many industrial sectors, they are predominantly used in a structured factory environment. In recent years, off-site robotics have been investigated extensively and there are some promising candidates emerging. One such category of robots is exoskeleton robots and this paper provides an in-depth assessment of their suitability in assisting human operators in undertaking manual operations typically found in the construction industry. This work aims to objectively assess the advantages and disadvantages of these two suits and provide recommendations for further improvements of similar system designs. The paper focuses on the passive exoskeleton robotic suits which are commercially available. Three types of activities are designed and a mechatronic methodology has been designed and implemented to capture visual data in order to assess these systems in comparison with normal human operations. The study suggests that these passive suits do reduce the effort required by human operators to undertake the same construction tasks as evidenced by the results from one focused study, though a number of improvements could be made to improve their performance for wider adoption.

As the treatment landscape for advanced melanoma continues to evolve, it is critical to focus on unmet needs and understand the cost of therapy. While Ipilimumab (IPI), an immunotherapy indicated for unresectable advanced melanoma, has been a mainstay of 1st-line treatment, there was no standard of care following progression until recently. The objective of this study was to examine real-world treatment patterns and healthcare costs following IPI use in advanced melanoma patients prior to the anti-PD-1 class approval. Adult stage III or IV melanoma patients treated with IPI were selected between April 1, 2011, and September 30, 2013, from a large U.S. commercial and Medicare claims database. Patients were evaluated for therapy after IPI, with an index date set as the first systemic therapy after IPI. Per-Patient Per-Month (PPPM) healthcare costs while on active treatment were evaluated from index until treatment discontinuation, inpatient death, end of insurance enrollment, or September 30, 2013. Of 361 eligible patients, 111 (30.7%) initiated subsequent systemic therapy (mean age, 57 years;64.9% male). The most common therapies, single-agent or combination, included vemurafenib (32.4%), paclitaxel (28.8%), temozolomide (20.7%), and carboplatin (17.1%). During a median follow-up of 130 days, mean [standard deviation] PPPM all-cause total healthcare costs were $20,383 [$18,988], of which $4800 (23.6%), $5899 (28.9%), and $9684 (47.5%) were related to melanoma drug costs, medical claims with a diagnosis of melanoma, and other (non-specified) utilization, respectively. When considering total care, the costs of U.S. patients with advanced melanoma post-IPI were substantial across all commonly used agents.

Background: Breast disease and breast cancer management form a major part of healthcare delivery. Surgical site occurrence (SSO) poses septic and oncological risks to patients. This study undertook a meta-analysis to identify key risk factors and interventions that may alter the incidence of SSO in patients undergoing breast surgery. Methods: An ethically approved, PROSPERO-registered meta-analysis following PRISMA guidelines and Cochrane Handbook for Systematic Reviews was undertaken of all published English articles using electronic databases from 2010 to 2017 incorporating MeSH terms “risk factors”, “surgical site infections”, “breast surgery”, and “interventions”. Articles scoring > 10 for non-comparative studies and >15 for comparative studies, using MINORS criteria were included. The OR or RR using random-effects, Mantel-Haenszel method were computed for each risk factor and intervention respectively with RevMan 5. Results: The pre-operative factors affecting breast surgery SSO were diabetes mellitus (OR = 2.52, CI = 1.78 - 3.59, p care (RR = 0.15, CI = 0.03 - 0.82, p = 0.03). Conclusions: This study iden

Vitis aestivalis “Norton/Cynthiana” is a grape native to North America and utilized in the commercial wine industry. The purpose of this research was to determine the appropriate time of year and/or time after last freeze that will yield the most successful propagation rate for Vitis aestivalis. It was hypothesized that the highest rate of propagation would be in early summer. During a year-long study (2015-2016), forty cuttings were taken semi-monthly from a vineyard, treated with 0.1% IBA and placed in a plant growth room set to spring conditions. Daily temperatures were recorded every day as well. In a follow-up study, cuttings were taken weekly from early spring before vine budding until late fall (2017) and treated as previous. After six weeks, cuttings were evaluated for root production. In both studies, rooting success rates were the highest in the month of June at 10.0% - 27.5%, with rates less than 7.5% for all other sampling dates. It was determined that the best time to propagate Vitis aestivalis is in June, 10 - 12 weeks after the last temperature below 0°C or eight to ten weeks after the first budding.

药物的副作用常常妨碍各种心血管疾病的治疗,例如利用心得安、利多卡因或乙胺碘呋酮进行抗心律失常的治疗时,由于会产生与药物有关的心脏和全身的副作用而使治疗复杂化。应用控释植入剂就可以避免这类问题。本文中所要讨论的是在心血管系统内的病灶区,用这种局部的给药方法在用药部位产生局部的高浓度,而全身的药物浓度则较低,可以既达到疗效又避免了副作用。药物可被混合在一种控释系统中,在基质中作为分散物,或作为“贮存”(reservoir)的片心。广泛应用的非降解基质聚合物有乙烯乙酸乙烯酯、硅橡胶和聚亚胺酯。将生物降解骨架材料用于控释植入剂常常是有利的。

Objectives: To examine predictors of progression-free survival in men with seminal vesicle invasion (SVI) following radical prostatectomy (RP) for clinically localized prostate cancer. Methods and Materials: Between 1999 and 2009, 1383 men underwent RP at Indiana University. Among them, 115 men were identified with SVI. Disease progression was defined by a rise in PSA ≥ 0.2 ng/ml, receipt of salvage therapy, progression to metastatic disease, or death. After excluding 13 patients for receiving adjuvant therapy, 102 were stratified according to surgical margin (SM) and lymph node (LN) status for Kaplan-Meier analysis of disease progression. Cox proportional hazards analyses of biochemical progression-free survival were undertaken with respect to margin status, pre-operative prostate specific antigen (PSA), tumor volume, age, and post-operative Gleason sum. Stem and leaf plot was undertaken for tumor volume by biochemical PFS. Results: Mean age was 61 years, median Gleason sum was 7, mean tumor volume was 9.7 ml, and mean pre-operative PSA was 13.6 ng/ml. Mean time to disease progression was 17 months. Mean follow-up was 37 months. Kaplan-Meier analysis revealed statistically insignificant differences in progression-free survival stratified by SM and LN status (p = 0.12). Cox univariate analyses revealed tumor volume to be a statistically significant predictor of progression free survival (p = 0.02). Stem and Leaf plot revealed tumor volume to be statistically significantly larger in patients who experienced biochemical recurrence, compared to those who did not. Conclusion: Tumor volume was associated progression-free survival in this cohort of SVI patients, while pathologic Gleason sum, PSA, margin and nodal status were not.
