Educating Home Health Nurses on Peristomal Skin Care

This Doctorate of Nursing Practice (DNP) project used a quasi-experimental, pre-test post-test design. It was conducted in the Denver area of Colorado. Purpose: The purpose of this quality improvement project is to improve the home health nurses’ knowledge regarding peristomal skin care through in-service education provided by a Certified Wound Ostomy and Continence Nurse (CWOCN). Goal: The goal is to improve the nurses’ knowledge on peristomal skin care, with the ultimate goal of positively impacting the care of the ostomy patients at home. Knowledge improvement was evaluated by administering an identical pre- and post-test on peristomal skin care. Objectives: 1.) Provide a one-hour, evidence-based in-service to increase the home health nurses’ knowledge on peristomal skin care. 2) Administer a pre-test to demonstrate baseline knowledge of participant nurses regarding peristomal skin care. 3) Administer a post-test to demonstrate knowledge acquisition. Methods: Regis University’s Internal Review Board approved the study. This author went to the different home health agencies to conduct the one-hour long in-service. Demographic forms were completed by the participants. A test was administered before and after the in-services. Descriptive and inferential statistics were used to analyze the data gathered. Results: 86 home health nurses participated in this project. A statistically significant improvement in mean knowledge scores was noted in the post-intervention assessment, suggesting that educational intervention was successful in increasing nurses’ knowledge on the topic. There was a significant difference in the pre- and post-test scores, pre-test (M=.5267, SD=.19062) and post-test (M=.7791, SD=.16458); t (85)=-9.521, p\u3c.001. CI=–.30502 to –.19963

Factors affecting the survival of patients with oesophageal carcinoma under radiotherapy in the north of Iran

Factors relevant to the survival of patients with oesophageal cancer under radiotherapy have been studied in northern Iran where its incidence is high. We conducted an analytical study using a historical cohort and information from the medical charts of patients with oesophageal cancer. Out of 523 patients referred to the Shahid Rajaii radiotherapy centre in Babolsar from 1992 to 1996, we followed 230 patients for whom an address was available in 1998. The frequency of prognostic factors among those not contacted was very similar to those included in the study. The data were analysed using survival analysis by the nonparametric method of Kaplan Meier and the Cox regression model to determine risk ratios (RR) of prognostic factors. Survival rates were 42% at 1 year, 21% at 2 years, and 8% at 5 years after diagnosis. Patients aged 50–64 were found to have poorer survival compared with those less than 50 (RR = 1.73, P = 0.03); the risk ratio for ages f = 65 was 1.88 (P = 0.03). Females had significantly better survival than males (RR = 0.71, P = 0.02). For each 100 rads dose of radiotherapy, the risk ratio was significantly decreased by 1% (RR = 0.99, P = 0.05); for each session of radiotherapy, the risk ratio was significantly decreased by 4% (RR = 0.96, P = 0.0001); for each square centimetre size of surface under radiotherapy, the risk ratio significantly increased (RR = 1.002, P = 0.04). We did not observe a significant difference on survival by histology, anatomical location of tumours, or type of treatment (P > 0.05). Prognosis is extremely poor. © 2001 Cancer Research Campaign http://www.bjcancer.co

Berberine Radiosensitizes Human Esophageal Cancer Cells by Downregulating Homologous Recombination Repair Protein RAD51

Esophageal squamous cell carcinomas (ESCC) have poor prognosis. While combined modality of chemotherapy and radiotherapy increases survival, most patients die within five years. Development of agents that confer cancer cell-specific chemo- and radiosensitivity may improve the therapy of ESCC. We here reported the discovery of berberine as a potent radiosensitizing agent on ESCC cells. by RNA interference similarly radiosensitized the cancer cells, and, conversely, introduction of exogenous RAD51 was able to significantly counteract the radiosensitizing effect of berberine, thus establishing RAD51 as a key determinant in radiation sensitivity. We also observed that RAD51 was commonly overexpressed in human ESCC tissues, suggesting that it is necessary to downregulate RAD51 to achieve high radio- or chemotherapeutic efficacy of ESCC in clinic, because overexpression of RAD51 is known to confer radio- and chemoresistance.Berberine can effectively downregulate RAD51 in conferring radiosensitivity on esophageal cancer cells. Its clinical application as an adjuvant in chemotherapy and radiotherapy of esophageal cancers should be explored

Quality of life assessment as a predictor of survival in non-small cell lung cancer

<p>Abstract</p> <p>Background</p> <p>There are conflicting and inconsistent results in the literature on the prognostic role of quality of life (QoL) in cancer. We investigated whether QoL at admission could predict survival in lung cancer patients.</p> <p>Methods</p> <p>The study population consisted of 1194 non-small cell lung cancer patients treated at our institution between Jan 2001 and Dec 2008. QoL was evaluated using EORTC-QLQ-C30 prior to initiation of treatment. Patient survival was defined as the time interval between the date of first patient visit and the date of death from any cause/date of last contact. Univariate and multivariate Cox regression evaluated the prognostic significance of QoL.</p> <p>Results</p> <p>Mean age at presentation was 58.3 years. There were 605 newly diagnosed and 589 previously treated patients; 601 males and 593 females. Stage of disease at diagnosis was I, 100; II, 63; III, 348; IV, 656; and 27 indeterminate. Upon multivariate analyses, global QoL as well as physical function predicted patient survival in the entire study population. Every 10-point increase in physical function was associated with a 10% increase in survival (95% CI = 6% to 14%, p < 0.001). Similarly, every 10-point increase in global QoL was associated with a 9% increase in survival (95% CI = 6% to 11%, p < 0.001). Furthermore, physical function, nausea/vomiting, insomnia, and diarrhea (p < 0.05 for all) in newly diagnosed patients, but only physical function (p < 0.001) in previously treated patients were predictive of survival.</p> <p>Conclusions</p> <p>Baseline global QoL and physical function provide useful prognostic information in non-small cell lung cancer patients.</p
