RESUMEN

The Nursing and Midwifery Council recognises that using simulated practice learning within the pre-registration nursing curriculum is a valuable way for students to develop nursing knowledge and skills. The University of Huddersfield developed simulated placements in the pre-registration nursing curriculum in 2021. Simulated placements are now embedded within all fields of the BSc and MSc programmes, providing structured, innovative learning experiences that embrace online technology in supporting the development of skills and knowledge relevant to all fields of nursing. Developing these placements has provided an opportunity for faculty staff to work collaboratively with clinical colleagues, service users and carers, academics and technologists. This article offers an overview of that work, addressing challenges, operational issues, and insight into some of the activities developed to support students' learning.

RESUMEN

BACKGROUND: Prostate cancer is the most common cancer among men in the UK. Prostate-specific antigen testing followed by biopsy leads to overdetection, overtreatment as well as undertreatment of the disease. Evidence of treatment effectiveness has lacked because of the paucity of randomised controlled trials comparing conventional treatments. OBJECTIVES: To evaluate the effectiveness of conventional treatments for localised prostate cancer (active monitoring, radical prostatectomy and radical radiotherapy) in men aged 50-69 years. DESIGN: A prospective, multicentre prostate-specific antigen testing programme followed by a randomised trial of treatment, with a comprehensive cohort follow-up. SETTING: Prostate-specific antigen testing in primary care and treatment in nine urology departments in the UK. PARTICIPANTS: Between 2001 and 2009, 228,966 men aged 50-69 years received an invitation to attend an appointment for information about the Prostate testing for cancer and Treatment (ProtecT) study and a prostate-specific antigen test; 82,429 men were tested, 2664 were diagnosed with localised prostate cancer, 1643 agreed to randomisation to active monitoring (n = 545), radical prostatectomy (n = 553) or radical radiotherapy (n = 545) and 997 chose a treatment. INTERVENTIONS: The interventions were active monitoring, radical prostatectomy and radical radiotherapy. TRIAL PRIMARY OUTCOME MEASURE: Definite or probable disease-specific mortality at the 10-year median follow-up in randomised participants. SECONDARY OUTCOME MEASURES: Overall mortality, metastases, disease progression, treatment complications, resource utilisation and patient-reported outcomes. RESULTS: There were no statistically significant differences between the groups for 17 prostate cancer-specific (p = 0.48) and 169 all-cause (p = 0.87) deaths. Eight men died of prostate cancer in the active monitoring group (1.5 per 1000 person-years, 95% confidence interval 0.7 to 3.0); five died of prostate cancer in the radical prostatectomy group (0.9 per 1000 person-years, 95% confidence interval 0.4 to 2.2 per 1000 person years) and four died of prostate cancer in the radical radiotherapy group (0.7 per 1000 person-years, 95% confidence interval 0.3 to 2.0 per 1000 person years). More men developed metastases in the active monitoring group than in the radical prostatectomy and radical radiotherapy groups: active monitoring, n = 33 (6.3 per 1000 person-years, 95% confidence interval 4.5 to 8.8); radical prostatectomy, n = 13 (2.4 per 1000 person-years, 95% confidence interval 1.4 to 4.2 per 1000 person years); and radical radiotherapy, n = 16 (3.0 per 1000 person-years, 95% confidence interval 1.9 to 4.9 per 1000 person-years; p = 0.004). There were higher rates of disease progression in the active monitoring group than in the radical prostatectomy and radical radiotherapy groups: active monitoring (n = 112; 22.9 per 1000 person-years, 95% confidence interval 19.0 to 27.5 per 1000 person years); radical prostatectomy (n = 46; 8.9 per 1000 person-years, 95% confidence interval 6.7 to 11.9 per 1000 person-years); and radical radiotherapy (n = 46; 9.0 per 1000 person-years, 95% confidence interval 6.7 to 12.0 per 1000 person years; p < 0.001). Radical prostatectomy had the greatest impact on sexual function/urinary continence and remained worse than radical radiotherapy and active monitoring. Radical radiotherapy's impact on sexual function was greatest at 6 months, but recovered somewhat in the majority of participants. Sexual and urinary function gradually declined in the active monitoring group. Bowel function was worse with radical radiotherapy at 6 months, but it recovered with the exception of bloody stools. Urinary voiding and nocturia worsened in the radical radiotherapy group at 6 months but recovered. Condition-specific quality-of-life effects mirrored functional changes. No differences in anxiety/depression or generic or cancer-related quality of life were found. At the National Institute for Health and Care Excellence threshold of £20,000 per quality-adjusted life-year, the probabilities that each arm was the most cost-effective option were 58% (radical radiotherapy), 32% (active monitoring) and 10% (radical prostatectomy). LIMITATIONS: A single prostate-specific antigen test and transrectal ultrasound biopsies were used. There were very few non-white men in the trial. The majority of men had low- and intermediate-risk disease. Longer follow-up is needed. CONCLUSIONS: At a median follow-up point of 10 years, prostate cancer-specific mortality was low, irrespective of the assigned treatment. Radical prostatectomy and radical radiotherapy reduced disease progression and metastases, but with side effects. Further work is needed to follow up participants at a median of 15 years. TRIAL REGISTRATION: Current Controlled Trials ISRCTN20141297.

Prostate cancer is the most common cancer in men and is often found through a blood test called a prostate-specific antigen test and through biopsies of the prostate. Over the years, these tests led to the detection of many small cancers that do not cause harm. Some prostate cancers are harmful, but it is difficult to recognise them early. When cancer is still inside the prostate, the conventional treatments are surgery or radiotherapy, which carry side effects including leaking urine and difficulty getting an erection, so another option is repeat investigations at regular intervals (active monitoring), with treatments given if the cancer progresses. These options needed to be compared in a study called a 'randomised trial' in which men agree to be allocated to one of the three treatments. In the Prostate testing for cancer and Treatment (ProtecT) study, 200,000 men aged 50­69 years were invited to have a prostate-specific antigen test. Of the 82,849 men who agreed to be tested, 1643 of whom had prostate cancer that was still contained in the prostate agreed to be allocated to one of the three treatments. After an average of 10 years of follow-up, 99% of men were alive in each of the treatment groups. However, when compared with active monitoring, surgery and radiotherapy reduced the risk of disease spreading outside the prostate by half. Patients reported that urinary leakage and sexual function were worst with surgery, and sexual and bowel functions were affected by radiotherapy. Men on active monitoring had a gradual decline in their urinary and sexual function, particularly as around half of them later had surgery or radiotherapy. Radiotherapy was the treatment that seemed to be the best value for money. The findings from the Prostate testing for cancer and Treatment (ProtecT) study can help men make decisions about being tested and which treatment to have if they are found to have cancer within the prostate. We now need to find out the longer-term effects of these treatments on how long men live and their quality of life.

RESUMEN

Objectives: To characterize treatment patterns and survival outcomes for patients with locally advanced or metastatic malignancy of the urothelial tract during a period immediately preceding the widespread use of immune checkpoint inhibitors in the UK. Patients and Methods: We retrospectively examined the electronic case notes of patients attending the Leeds Cancer Center, UK with locally advanced or metastatic urothelial carcinoma, receiving chemotherapy between January 2003 and March 2017. Patient characteristics, treatment patterns, and outcomes were collected. Summary and descriptive statistics were calculated for categorical and continuous variables as appropriate. The Kaplan-Meier method was used to estimate median survival and Cox regression proportional hazards model was used to explore relationships between clinical variables and outcome. Results: Two hundred and sixteen patients made up the study cohort, with a median age of 66 years (range: 35-83) and 72.7% being male. First-line treatment consisted of either a cisplatin- (44%) or carboplatin-based regimen (48%) in the majority of patients. Twenty seven percent of patients received a second-line of treatment (most commonly single-agent paclitaxel) following a first-line platinum containing regimen. Grade 4 neutropenia was observed in 19 and 27% of those treated with a first-line cisplatin- and carboplatin-based regimen, respectively. The median overall survival (mOS) of the study cohort was estimated to be 16.2 months (IQR: 10.6-28.3 months). Receipt by patients of cisplatin-based chemotherapy was associated with a longer mOS and this association persisted when survival analysis was adjusted for age, sex, performance status and presence of distant metastases. Conclusions: This study provides a useful benchmark for outcomes achieved in a real-world setting for patients with locally advanced or metastatic UC treated with chemotherapy in the immediate pre-immunotherapy era.

RESUMEN

The purpose of this article is to introduce the concept of design-based research, its appropriateness in creating education-based models, and to describe the process of developing such a model. The model was designed as part of the Nurse Educator Simulation based learning project, funded by the EU's Lifelong Learning program (2013-1-DK1-LEO05-07053). The project partners were VIA University College, Denmark, the University of Huddersfield, UK and Metropolia University of Applied Sciences, Finland. As an outcome of the development process, "the NESTLED model for educating simulation facilitators" (NESTLED model) was generated. This article also illustrates five design principles that could be applied to other pedagogies.

RESUMEN

BACKGROUND: There is a pragmatic and often inconsistent approach of embedding simulation-based learning into nursing programmes. This paper details a European collaboration that designed a model for educator facilitation for educators utilizing simulation-based education. OBJECTIVES: The objectives of the study were to develop a model to educate the educators who deliver simulation-based learning and to test to which extent this model could be transferred to education providers in different national settings. METHODS: This model, its transferability and feasibility, was tested across three European countries. Educators from three Schools of Nursing participated in the study. Design-based Research was used as an overall methodology. Data were collected by the use of pre- and post-programme questionnaires and focus groups. RESULTS: The content of the NESTLED model is consistent with the needs of the participants. The testing also demonstrated that the model is transferable across-countries. Additionally, the participants' preferences regarding amount of time and pre-reading for the different sessions vary depending on the background and level of seniority of the individual participant. CONCLUSION: The testing of the NESTLED model demonstrated that participants gained confidence and knowledge from undertaking the programme. Delivering the NESTLED model across-countries was found to be feasible, but flexibility is required in terms of logistical delivery of the programme.

RESUMEN

BACKGROUND: The comparative effectiveness of treatments for prostate cancer that is detected by prostate-specific antigen (PSA) testing remains uncertain. METHODS: We compared active monitoring, radical prostatectomy, and external-beam radiotherapy for the treatment of clinically localized prostate cancer. Between 1999 and 2009, a total of 82,429 men 50 to 69 years of age received a PSA test; 2664 received a diagnosis of localized prostate cancer, and 1643 agreed to undergo randomization to active monitoring (545 men), surgery (553), or radiotherapy (545). The primary outcome was prostate-cancer mortality at a median of 10 years of follow-up. Secondary outcomes included the rates of disease progression, metastases, and all-cause deaths. RESULTS: There were 17 prostate-cancer-specific deaths overall: 8 in the active-monitoring group (1.5 deaths per 1000 person-years; 95% confidence interval [CI], 0.7 to 3.0), 5 in the surgery group (0.9 per 1000 person-years; 95% CI, 0.4 to 2.2), and 4 in the radiotherapy group (0.7 per 1000 person-years; 95% CI, 0.3 to 2.0); the difference among the groups was not significant (P=0.48 for the overall comparison). In addition, no significant difference was seen among the groups in the number of deaths from any cause (169 deaths overall; P=0.87 for the comparison among the three groups). Metastases developed in more men in the active-monitoring group (33 men; 6.3 events per 1000 person-years; 95% CI, 4.5 to 8.8) than in the surgery group (13 men; 2.4 per 1000 person-years; 95% CI, 1.4 to 4.2) or the radiotherapy group (16 men; 3.0 per 1000 person-years; 95% CI, 1.9 to 4.9) (P=0.004 for the overall comparison). Higher rates of disease progression were seen in the active-monitoring group (112 men; 22.9 events per 1000 person-years; 95% CI, 19.0 to 27.5) than in the surgery group (46 men; 8.9 events per 1000 person-years; 95% CI, 6.7 to 11.9) or the radiotherapy group (46 men; 9.0 events per 1000 person-years; 95% CI, 6.7 to 12.0) (P<0.001 for the overall comparison). CONCLUSIONS: At a median of 10 years, prostate-cancer-specific mortality was low irrespective of the treatment assigned, with no significant difference among treatments. Surgery and radiotherapy were associated with lower incidences of disease progression and metastases than was active monitoring.

RESUMEN

OBJECTIVE: To determine the relationship of age to side-effects leading to discontinuation of treatment in patients with stage Ta-T1 non-muscle-invasive bladder cancer (NMIBC) treated with maintenance bacille Calmette-Guérin (BCG). PATIENTS AND METHODS: We evaluated toxicity for 487 eligible patients with intermediate- or high-risk Ta-T1 (without carcinoma in situ) NMIBC randomised to receive 3 years of maintenance BCG therapy (247 BCG alone and 240 BCG + isoniazid) in European Organisation for Research and Treatment of Cancer Genito-Urinary Group trial 30911. The percentage of patients who stopped for toxicity and the number of treatment cycles that they received were compared in four age groups, ≤60, 61-70, 71-75 and >75 years, using the Mantel-Haenszel chi-square test for trend. RESULTS: The percentage of patients stopping BCG for toxicity was 17.9% in patients aged ≤60 years, 21.9% in patients aged 61-70 years, 22.9% in patients aged 71-75 years, and 16.4% in patients aged >75 years (P = 0.90). For both systemic and local side-effects, there was likewise no significant difference. CONCLUSION: In patients with intermediate- and high-risk Ta-T1 NMIBC treated with BCG, no differences in toxicity as a reason for stopping treatment were detected based on patient age.

RESUMEN

BACKGROUND: There are no prognostic factor publications on stage Ta-T1 non-muscle-invasive bladder cancer (NMIBC) treated with 1-3 yr of maintenance bacillus Calmette-Guérin (BCG). OBJECTIVE: To determine prognostic factors in NMIBC patients treated with 1-3 yr of BCG after transurethral resection of the bladder (TURB), to derive nomograms and risk groups, and to identify high-risk patients who should be considered for early cystectomy. DESIGN, SETTING, AND PARTICIPANTS: Data for 1812 patients were merged from two European Organization for Research and Treatment of Cancer randomized phase 3 trials in intermediate- and high-risk NMIBC. INTERVENTION: Patients received 1-3 yr of maintenance BCG after TURB and induction BCG. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Prognostic factors for risk of early recurrence and times to late recurrence, progression, and death were identified in a training data set using multivariable models and applied to a validation data set. RESULTS AND LIMITATIONS: With a median follow-up of 7.4 yr, 762 patients recurred; 173 progressed; and 520 died, 83 due to bladder cancer (BCa). Statistically significant prognostic factors identified by multivariable analyses were prior recurrence rate and number of tumors for recurrence, and tumor stage and grade for progression and death due to BCa. T1G3 patients do poorly, with 1- and 5-yr disease-progression rates of 11.4% and 19.8%, respectively, and 1- and 5-yr disease-specific death rates of 4.8% and 11.3%. Limitations include lack of repeat transurethral resection in high-risk patients and exclusion of patients with carcinoma in situ. CONCLUSIONS: NMIBC patients treated with 1-3 yr of maintenance BCG have a heterogeneous prognosis. Patients at high risk of recurrence and/or progression do poorly on currently recommended maintenance schedules. Alternative treatments are urgently required. PATIENT SUMMARY: Non-muscle-invasive bladder cancer patients at high risk of recurrence and/or progression do poorly on currently recommended bacillus Calmette-Guérin maintenance schedules, and alternative treatments are urgently required. TRIAL REGISTRATION: Study 30911 was registered with the US National Cancer Institute clinical trials database (protocol ID: EORTC 30911). Study 30962 was registered at ClinicalTrials.gov, number NCT00002990; http://clinicaltrials.gov/ct2/show/record/NCT00002990.

RESUMEN

BACKGROUND: The IO route is an established method of obtaining vascular access in children in acute and emergency situations and is now increasingly being used in adults as an alternative to intravenous access, yet a paucity of evidence exists regarding its use, effectiveness and implementation. AIM AND OBJECTIVES: The aim of this literature review is to present a detailed investigation critiquing contemporary practices of intraosseous (IO) vascular access in adult patients. Specific objectives identified led to the exploration of clinical contexts, IO device/s and anatomical sites; education and training requirements; implications and recommendations for emergency health care practice and any requirements for further research. SEARCH STRATEGIES: An exploratory literature review was undertaken in acknowledgement of the broad and complex nature of the project aim. Five electronic search engines were examined iteratively from June 2013 to February 2014. The search terms were 'intraosseous' and 'adult' which were purposely limited because of the exploratory nature of the review. Studies that met the inclusion criteria of primary research articles with an adult focus were included. Research with a paediatric focus was excluded. Secondary research, reviews, case reports, editorials and opinion papers were excluded. CONCLUSION: IO vascular access is considered an alternative intravascular access route although debate considering the preferred anatomical site is ongoing. Documented practices are only established in pre-hospital and specialist emergency department settings; however, variety exists in policy and actual practice. Achieving insertion competence is relatively uncomplicated following minimal preparation although ongoing skill maintenance is less clear. IO vascular access is associated with minimal complications although pain is a significant issue for the conscious patient especially during fluid administration. RELEVANCE TO CLINICAL PRACTICE: The IO route is clearly a valuable alternative to problematic intravascular access. However, further research, including cost effectiveness reviews, is required to gain clarity of whole acute care approaches.

RESUMEN

OBJECTIVES: This paper presents the results of a systemised rapid review and synthesis of the literature undertaken to identify competencies required by nurse educators to facilitate simulation-based learning (SBL). DESIGN: An international collaboration undertook a protocol-based search, retrieval and critical review. DATA SOURCES: Web of Science, PubMed, CINAHL Plus, PsycInfo, ERIC, the Cochrane Library and Science Direct. The search was limited to articles published in English, 2002-2012. REVIEW METHODS: The search terms used: nurse*, learn*, facilitator, simula*, lecturer, competence, skill*, qualificat*, educator, health care, "patient simulation", "nursing education" and "faculty". The search yielded 2156 "hits", following a review of the abstracts, 72 full-text articles were extracted. These were screened against predetermined inclusion/exclusion criteria and nine articles were retained. Following critical appraisal, the articles were analyzed using an inductive approach to extract statements for categorization and synthesis as competency statements. RESULTS: This review confirmed that there was a modest amount of empirical evidence on which to base a competency framework. Those papers that provided descriptions of educator preparation identified simulation-based workshops, or experiential training, as the most common approaches for enhancing skills. SBL was not associated with any one theoretical perspective. Delivery of SBL appeared to demand competencies associated with planning and designing simulations, facilitating learning in "safe" environments, expert nursing knowledge based on credible clinical realism, reference to evidence-based knowledge and demonstration of professional values and identity. CONCLUSIONS: This review derived a preliminary competency framework. This needs further development as a model for educators delivering SBL as part of nursing curricula.

RESUMEN

OBJECTIVE: To investigate the efficacy of diethylstilboestrol (DES) in patients with advanced prostate cancer refractory to androgen suppression. METHODS: This retrospective study comprises 194 patients with prostate cancer treated with DES (1 mg daily) between 1976 and 2010. Study outcome parameters included demographic data, tumour characteristics, treatment history, prostate-specific antigen (PSA) responses, radiologic studies, adverse events and overall survival. RESULTS: At initiation of oestrogen therapy the mean patient age was 69 years (range: 48-89) and the median PSA was 96 ng/ml (range: 1.9-9,500). The median duration of prior prostate cancer treatment was 29 months (range: 1-365). DES was the second-line treatment in 58 patients and the third/fourth-line therapy in 136 men. A formal (≥50%) PSA response was observed in 95 patients (48.9%) and the median time to progression (TTP) was 250 days (95% CI, 180-360) for this group. An additional 62 patients (31.9%) had a partial PSA response with a median TTP of 150 days (95% CI, 92-180). Thirty-seven patients (19.1%) did not have a PSA response and the median TTP was 90 days (95% CI, 90-97). The median overall survival from the start of oestrogen therapy for the entire cohort was 576 days (95% CI, 482-690). The median overall survival of patients who had a formal (≥50%), partial (<50%) and no PSA response was 756 (95% CI, 670-1,429), 428 (95% CI, 340-630) and 329 (95% CI, 287-510) days, respectively. Thirty-nine patients (20.1%) were still alive at the end of the study. No treatment-related deaths occurred. CONCLUSIONS: In the age of chemotherapy this study highlights the efficacy of oestrogen therapy in castration-refractory prostate cancer. The optimal point in the therapeutic pathway at which DES should be prescribed remains to be established.

RESUMEN

OBJECTIVE: The aim of this study was to validate and compare the performance of preoperative risk assessment tools in a population of men treated with radical prostatectomy at a single European institution. MATERIAL AND METHODS: Patients were identified from databases of radical prostatectomy between 1996 and 2011 from a single UK centre. Information was obtained on demographics, prostate-specific antigen, staging, biopsy and specimen histopathology, and follow-up. Data were inputted into the Memorial Sloan-Kettering Cancer Center (MSKCC), Partin 1997 and Makarov/Partin 2007 nomograms, and the University of California San Francisco-Cancer of the Prostate Risk Assessment tool (UCSF-CAPRA). The risks of extracapsular extension (ECE), seminal vesicle invasion (SVI) and lymph-node involvement (LNI) were calculated and compared with known outcomes. Nomogram performance was measured using Hosmer-Lemeshow (HL) goodness-of-fit tests, calculating concordance indices (c-indices) and calibration curves. RESULTS: Data were obtained for 541 patients. Prediction of ECE was relatively poor using all nomograms, with the Makarov/Partin 2007 the most accurate at prediction over the range of risk stratification (HL 9.9, c-index 0.62). Predictions of SVI and LNI were better than for ECE, with the MSKCC nomogram performing best for SVI (HL 10.9, c-index 0.73) and all nomograms performing well for LNI prediction (c-indices 0.8 to 0.815). CAPRA predicted best for SVI (OR 1.49, 95% confidence interval 1.27-1.74). CONCLUSIONS: To the authors' knowledge, this is the first head-to-head comparison of the accuracy of these commonly used risk calculators in a North European population. Caution should be used when counselling patients using nomograms. Although nomograms may be used as a guide, patients should be warned that they often have not been validated on different European populations and may give misleading information regarding a patient's specific risks.

RESUMEN

BACKGROUND: Although maintenance bacillus Calmette-Guérin (BCG) is the recommended treatment in high-risk non-muscle-invasive bladder cancer (NMIBC), its efficacy in older patients is controversial. OBJECTIVE: To determine the effect of age on prognosis and treatment outcome in patients with stage Ta T1 NMIBC treated with maintenance BCG. DESIGN, SETTING, AND PARTICIPANTS: A total of 957 patients with intermediate- or high-risk Ta T1 (without carcinoma in situ) NMIBC were randomized in European Organization for Research and Treatment of Cancer (EORTC) trial 30911 comparing six weekly instillations of epirubicin, BCG, and BCG plus isoniazid followed by three weekly maintenance instillations over 3 yr. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Cox multivariate proportional hazards regression models were used to assess the relative importance of age for recurrence, progression, overall survival, and NMIBC-specific survival with adjustment for EORTC risk scores. RESULTS AND LIMITATIONS: Overall, 822 eligible patients were included: 546 patients in the BCG with or without INH arms and 276 in the epirubicin arm. In patients treated with BCG with or without INH, 34.1% were >70 yr of age and 3.7% were >80 yr. With a median follow-up of 9.2 yr, patients >70 yr had a shorter time to progression (p=0.028), overall survival (p<0.001), and NMIBC-specific survival (p=0.049) after adjustment for EORTC risk scores in the multivariate analysis. The time to recurrence was similar compared with the younger patients. BCG was more effective than epirubicin for all four end points considered, and there was no evidence that BCG was any less effective compared with epirubicin in patients >70 yr. CONCLUSIONS: In intermediate- and high-risk Ta T1 urothelial bladder cancer patients treated with BCG, patients >70 yr of age have a worse long-term prognosis; however, BCG is more effective than epirubicin independent of patient age. PATIENT SUMMARY: Intravesical bacillus Calmette-Guérin for non-muscle-invasive bladder cancer is less effective in patients >70 yr of age, but it is still more effective than epirubicin. TRIAL REGISTRATION: This study was registered with the US National Cancer Institute clinical trials database (protocol ID: EORTC 30911; http://www.cancer.gov/clinicaltrials/search/view?cdrid=77075&version=HealthProfessional&protocolsearchid=12442243#StudyIdInfo_CDR0000077075).

RESUMEN

The incidence of prostate cancer in transsexual patients is very low with only few reported cases. Many years before presenting with prostate cancer, these patients receive hormone ablation as a part of their gender therapy. Their disease is already defined as castrate resistant, and the treatment and follow-up of such patients remains a challenge. We report a case of a male-to-female transgender woman who was diagnosed with metastatic prostate cancer, 31 years post-feminization.

RESUMEN

Current evidence indicates that dysregulation of the host inflammatory response to infectious agents is central to the mortality of patients with sepsis. Strategies to block inflammatory mediators such as PAF have been investigated as adjuvant therapies for sepsis. PAF-AH, the enzyme responsible for PAF degradation, showed positive results in pre-clinical studies and phase II clinical trials, but the results of a phase III study were disappointing. In this study, we investigated the potential protective mechanism of PAF-AH in sepsis using the murine model of cecal ligation and puncture (CLP). Treatment with rPAF-AH increased peritoneal fluid levels of the anti-inflammatory mediators MCP-1/CCL2 after CLP. The numbers of bacteria (CFU) in the peritoneal cavity were decreased in the rPAF-AH-treated group, indicating more efficient bacterial clearance after rPAF-AH treatment. Interestingly, we observed increased levels of nitric oxide (NO) after PAF-AH administration, and rPAF-AH treatment did not decrease CFU numbers either in iNOS-deficient mice or in CCR2-deficient mice. We concluded that administration of exogenous rPAF-AH reduced inflammatory injury, altered cytokine levels and favored bacterial clearance with a clear impact on mortality through modulation of MCP-1/CCL2 and NO levels in a clinically relevant sepsis model.

RESUMEN

BACKGROUND: Castration resistance occurs in most patients with metastatic hormone-sensitive prostate cancer who are receiving androgen-deprivation therapy. Replacing androgens before progression of the disease is hypothesized to prolong androgen dependence. METHODS: Men with newly diagnosed, metastatic, hormone-sensitive prostate cancer, a performance status of 0 to 2, and a prostate-specific antigen (PSA) level of 5 ng per milliliter or higher received a luteinizing hormone-releasing hormone analogue and an antiandrogen agent for 7 months. We then randomly assigned patients in whom the PSA level fell to 4 ng per milliliter or lower to continuous or intermittent androgen deprivation, with patients stratified according to prior or no prior hormonal therapy, performance status, and extent of disease (minimal or extensive). The coprimary objectives were to assess whether intermittent therapy was noninferior to continuous therapy with respect to survival, with a one-sided test with an upper boundary of the hazard ratio of 1.20, and whether quality of life differed between the groups 3 months after randomization. RESULTS: A total of 3040 patients were enrolled, of whom 1535 were included in the analysis: 765 randomly assigned to continuous androgen deprivation and 770 assigned to intermittent androgen deprivation. The median follow-up period was 9.8 years. Median survival was 5.8 years in the continuous-therapy group and 5.1 years in the intermittent-therapy group (hazard ratio for death with intermittent therapy, 1.10; 90% confidence interval, 0.99 to 1.23). Intermittent therapy was associated with better erectile function and mental health (P<0.001 and P=0.003, respectively) at month 3 but not thereafter. There were no significant differences between the groups in the number of treatment-related high-grade adverse events. CONCLUSIONS: Our findings were statistically inconclusive. In patients with metastatic hormone-sensitive prostate cancer, the confidence interval for survival exceeded the upper boundary for noninferiority, suggesting that we cannot rule out a 20% greater risk of death with intermittent therapy than with continuous therapy, but too few events occurred to rule out significant inferiority of intermittent therapy. Intermittent therapy resulted in small improvements in quality of life. (Funded by the National Cancer Institute and others; ClinicalTrials.gov number, NCT00002651.).

RESUMEN

In the United Kingdom (UK) simulation learning has been recognised in the form of a regulatory agreement that may replace hours from clinical practice. This integration has become an embedded feature of the pre-registration nursing programme at a University in the North of England, along with strategic investment in staff and simulation suites developed to underpin this curriculum change albeit in the absence of sparse empirical evidence, hence the rationale for the study which was designed to explore the relationship between simulation, theory and practice. The study features a thematic analysis of evaluation questionnaires from pre-registration student nurses (n=>500) collected over a 2 year period which informed subsequent focus group interviews to explore the themes in more detail. Consistent data findings were the students' positive response to simulation as a learning approach facilitating the application of theory in a safe controlled environment. Students reported that they felt prepared for practice, recognising that simulated learning improved their humanistic and problem solving abilities as well as the development of psychomotor, technical skills, and overall confidence. The theory-practice gap is a recurring narrative in the nursing literature, the findings of this study recognises that simulation offers an opportunity to enact the integration of theory and practice illuminating this relationship in a controlled environment thus, reinforcing the theory-practice relationship for nursing students.

RESUMEN

Diacylglycerol (DAG) is an important lipid second messenger. DAG signalling is terminated by conversion of DAG to phosphatidic acid (PA) by diacylglycerol kinases (DGKs). The neuronal synapse is a major site of DAG production and action; however, how DGKs are targeted to subcellular sites of DAG generation is largely unknown. We report here that postsynaptic density (PSD)-95 family proteins interact with and promote synaptic localization of DGKι. In addition, we establish that DGKι acts presynaptically, a function that contrasts with the known postsynaptic function of DGKζ, a close relative of DGKι. Deficiency of DGKι in mice does not affect dendritic spines, but leads to a small increase in presynaptic release probability. In addition, DGKι-/- synapses show a reduction in metabotropic glutamate receptor-dependent long-term depression (mGluR-LTD) at neonatal (∼2 weeks) stages that involve suppression of a decrease in presynaptic release probability. Inhibition of protein kinase C normalizes presynaptic release probability and mGluR-LTD at DGKι-/- synapses. These results suggest that DGKι requires PSD-95 family proteins for synaptic localization and regulates presynaptic DAG signalling and neurotransmitter release during mGluR-LTD.

RESUMEN

BACKGROUND: Intravesical chemotherapy and bacillus Calmette-Guérin (BCG) reduce the recurrence rate in patients with stage Ta T1 urothelial bladder cancer; however, the benefit of BCG relative to chemotherapy for long-term end points is controversial, especially in intermediate-risk patients. OBJECTIVE: The aim of the study was to compare the long-term efficacy of BCG and epirubicin. DESIGN, SETTING, AND PARTICIPANTS: From January 1992 to February 1997, 957 patients with intermediate- or high-risk stage Ta T1 urothelial bladder cancer were randomized after transurethral resection to one of three treatment groups in the European Organization for Research and Treatment of Cancer Genito-Urinary Group phase 3 trial 30911. INTERVENTION: Patients received six weekly instillations of epirubicin, BCG, or BCG plus isoniazid (INH) followed by three weekly maintenance instillations at months 3, 6, 12, 18, 24, 30, and 36. MEASUREMENTS: End points were time to recurrence, progression, distant metastases, overall survival, and disease-specific survival. RESULTS AND LIMITATIONS: With 837 eligible patients and a median follow-up of 9.2 yr, time to first recurrence (p<0.001), distant metastases (p=0.046), overall survival (p=0.023), and disease-specific survival (p=0.026) were significantly longer in the two BCG arms combined as compared with epirubicin; however, there was no difference for progression. Three hundred twenty-three patients with stage T1 or grade 3 tumors were high risk, and the remaining 497 patients were intermediate risk. The observed treatment benefit was at least as large, if not larger, in the intermediate-risk patients compared with the high-risk patients. CONCLUSIONS: In patients with intermediate- and high-risk stage Ta and T1 urothelial bladder cancer, intravesical BCG with or without INH is superior to intravesical epirubicin not only for time to first recurrence but also for time to distant metastases, overall survival, and disease-specific survival. The benefit of BCG is not limited to just high-risk patients; intermediate-risk patients also benefit from BCG.
