Colostomy and ileostomy care in nursing education: Which is more effective: Synchronous or asynchronous?

Objective: To compare the effects of synchronous and asynchronous training on the academic achievements and e-learning attitudes of nursing student trained in colostomy and ileostomy care. Method: The quasi-experimental, descriptive study was conducted at the Nursing Department of a health facility after approval from the Tekirdag Namik Kemal University, Tekirdag, Turkey, from May to June 2020, and comprised nursing students who were divided in intervention group A and control group B. Those in group A were given synchronous training on colostomy and ileostomy care using active learning techniques on an online platform, while those group B received their training only asynchronously. Data was collected using Colostomy and Ileostomy Knowledge Test, and the e-Learning Attitude Scale at baseline and post-intervention. Data was analysed using SPSS 17. Results: Of the 154 students, there were 77(50%) in each of the two groups. Overall, 53(34.4%) students were in 2nd grade, 60(39%) in 3rd, and 41(26.6%) in 4th grade of their training. The mean age of the sample was 21.50±1.10 years. Post-intervention mean scores for knowledge and e-learning tendency were significantly higher in both the groups compared to the baseline (p<0.01). Mean score for e-learning avoidance was significantly lower and mean knowledge score was significantly higher in group A than group B (p<0.05). Conclusion: The application of active learning activities among students was found to have a positive effect on nursing education compared to asynchronous teaching.

Optimal Transmission Power Level Sets for Lifetime Maximization in Wireless Sensor Networks

15th IEEE Sensors Conference (2016 : Orlando, FL)In Wireless Sensor Networks (WSNs) data transmission by using the highest available power level leads to energy wastage on certain links. Therefore, assigning the optimal transmission power for each link in a WSN is necessary to prolong the network lifetime. Transceivers of WSN nodes perform transmission power control by selecting one of the available discrete transmission power levels. As such, the power level set of a WSN transceiver is an important tool for achieving energy efficiency, yet, the power level sets are determined without considering their effects on WSN lifetime. In this study, we investigate the characteristics of the optimal transmission power level sets from WSN lifetime maximization perspective

Usage of HCV viremic organs in liver transplantation to anti-HCV negative recipients: The current status and review of literature

Liver transplantation is the main curative therapy for end-stage liver disease. The number of transplanted organs is increasing globally. However, the number of available organs in the pool is insufficient, considering the excessive number of patients on the waiting list, which is a major concern for transplant programs. Hepatitis C infection (HCV) is a common indication for liver transplantation, and in recent years, a major progress has been made in its treatment with direct-acting antiviral (DAA) agents. HCV-positive livers have been transplanted to HCV-positive recipients for a long time. The high rate of sustained virologic response through DAA has brought new treatment options for the patients during the pre- and post-transplantation periods. Recently, there have been few reports of transplanting the available HCV-positive organs to HCV noninfected recipients. However, there is not yet an agreement on the optimal selection of patients who would benefit from such transplantation, and this has become a current topic of interest. Thus, we aim to review the current literature on this evolving topic

Synthesis of a benzotriazole bearing alternating copolymer for organic photovoltaic applications

A low band gap donor-acceptor (D-A) copolymer PTBTBDT, namely, poly(2-dodecyl-4,7-di(thiophen-2-yl)-2H-benzo[d][1,2,3]triazole-alt-4,8-bis(2-ethylhexyloxy) benzo[1,2-b:4,5-b'] dithiophene), was designed and synthesized via a Pd-catalyzed Stille polycondensation reaction. The polymer was characterized using H-1 NMR spectroscopy, UV-vis absorption spectroscopy, cyclic voltammetry, and gel permeation chromatography (GPC). PTBTBDT has good solubility in common organic solvents, good thermal stability, broad absorption, low band gap and exhibits not only high hole mobility but also moderate photovoltaic properties. PTBTBDT displays broad absorption in the wavelength range from 300 nm to 630 nm, and its HOMO and LUMO energy levels were calculated to be -4.98 eV and -3.34 eV, respectively. Bulk heterojunction solar cells were fabricated using PTBTBDT as the electron donor and PC70BM as the acceptor. The device exhibits a power conversion efficiency of 2.12% with a current density of 5.45 mA cm(-2), an open-circuit voltage of 0.72 V, and a fill factor of 54% under the illumination of AM 1.5 G, 100 mW cm(-2). Under similar device fabrication conditions, the PTBTBDT based device showed considerably improved efficiency among its previously synthesized counterparts, i.e. PBDTDTBTz and PBDTBTz based devices, which have 1.7% and 1.4% efficiencies, respectively. The hole mobility of the PTBTBDT : PC70BM (1 : 2 w/w) blend reached up to 1.47 x 10(-3) cm(2) V-1 s(-1) as calculated by the space-charge-limited current (SCLC) method. By side-chain engineering, this study demonstrates a good example of tuning the absorption range, energy level, charge transport, and photovoltaic properties of polymers

Impact Of Treatment Strategies On Local Control And Survival In Uterine Carcinosarcomas In Turkey

Background: The purpose of this study was to determine the clinical characteristics, patterns of recurrence and survival outcomes in patients with uterine carcinosarcomas treated in our institution. Materials and Methods: Records of 26 patients diagnosed between 2007 and 2011 with uterine carcinosarcoma were retrospectively evaluated for demographic features, tumor characteristics, treatment regimens and patient outcomes in terms of DFS and OS Results: Median age was 61 (range 43-78). 10 patients (38%) had stage I disease at diagnosis, 3 (12%) had stage II, 4 (15%) had stage III and 9 (35%) had stage IV. Sixteen patients (62%) received chemotherapy with paclitaxel and carboplatin for 6 cycles. One patient underwent radiotherapy. Median follow up was 17 months. Sixteen patients relapsed and 13 died during follow up. Considering recurrence, 5 out of 16 patients had lung metastases, one had brain metastases and 9 had only intraabdominal recurrence. The 3 year DFS was 37% and the 3 year OS was 30%. Conclusions: Our data show that uterine carcinosarcomas tend to be at advanced stage at diagnosis and despite the use of chemotherapy, overall prognosis is poor. Surgery remains the mainstay of treatment. More effective adjuvant strategies are needed to reduce relapse and death rates.WoSScopu
