RESUMEN
Objective: Specialist genitourinary (GU) nurses provide care to a broad and diverse group of patients diagnosed with kidney, bladder, prostate, testicular, adrenal, and penile cancer. The purpose of this study was to identify GU cancer nurse perspectives of perceived unmet needs in service provision, specific educational and research priorities. Methods: A concurrent mixed methods study design incorporated quantitative and qualitative data collection from the GU Cancer nurses workforce in Australia. Quantitative data collected using an electronic survey instrument and were analysed using descriptive statistics. Qualitative data collected through semi-structured interviews and coded for thematic analysis. Ethical approval was gained. Results: Fifty responses were received from the electronic survey. 39/50 (78%) were female and 35 (70%) were metropolitan based. The highest domains of perceived unmet needs related to psychological/emotional needs - 17/23 (74%), intimacy needs - 15/23 (65%) and informational needs - 13/23 (57%). The themes from the qualitative interviews identified: (1) Patient needs - lack of tumour specific contact for cancer patients, fragmented delivery of cancer care, perception of better access to supportive care for public patients, lack of access to supportive care screening tools for needs assessment. (2) Educational needs - lack of GU specific cancer educational resources/learning opportunities and barriers to accessing educational opportunities. (3) Research priorities - impact on carers/partners, specific needs of different GU cancers, future focus on genetic testing/counselling, interventions for financial toxicity and development of models of care for geriatric GU patients. Conclusions: Specialist GU cancer nurses support a broad group of patients. Given the prominence of addressing unmet cancer care needs among people with GU cancers in this study, cancer nursing as a discipline alongside the multidisciplinary team, requires innovative solutions to overcome fragmented care which is often highly complex, and develop individualised and integrated care across the cancer care continuum. We encourage clinicians, researchers, policy makers, people affected by cancer, and their care networks, to continue to drive innovation by (1) Embedding an integrated approach to cancer nursing, (2) Implementation of shared care, (3) Implementation of patient navigation, (4) Embracing emerging technologies, (5) Future focus on education, and (6) Future focus on nurse-led research.
RESUMEN
Tourniquet-imposed ischemia-reperfusion of extremities generates reactive oxygen and nitrogen species (RONS), which can disrupt intermediary metabolism and ATP production. This study tested the hypothesis that fluid resuscitation with pyruvate, a natural antioxidant and metabolic fuel, ameliorates the deleterious effects of ischemia-reperfusion on intermediary metabolism in skeletal muscle. Anesthetized male goats (â¼25 kg) were bled to a mean arterial pressure of 48 ± 1 mmHg and then subjected to 90 min hindlimb ischemia with a tourniquet and femoral crossclamp, followed by 4-h reperfusion. Lactated Ringers (LR) or pyruvate Ringers (PR) was infused intravenous for 90 min, from 30 min ischemia to 30 min reperfusion, to deliver 0.05 mmol kg(-1) min(-1) lactate or pyruvate. Time controls (TC) underwent neither hemorrhage nor hindlimb ischemia. Lipid peroxidation product 8-isoprostane, RONS-sensitive aconitase and creatine kinase activities, antioxidant superoxide dismutase activity, and phosphocreatine phosphorylation potential ([PCr]/[{Cr}{P(i)}]), an index of tissue energy state, were measured in reperfused gastrocnemius at 90 min resuscitation (n = 6 all groups) and 3.5 h post-resuscitation (n = 8 TC, 9 LR, 10 PR). PR more effectively than LR suppressed 8-isoprostane formation, prevented inactivation of aconitase and creatine kinase, doubled superoxide dismutase activity, and augmented [PCr]/([Cr][P(i)]). Pyruvate-enriched Ringer's is metabolically superior to Ringer's lactate for fluid resuscitation of tourniqueted muscle.

BACKGROUND: Up to now, the role of adjuvant radiation therapy and the extent of lymph node dissection for early stage endometrial cancer are controversial. In order to clarify the current position of the given adjuvant treatment options, a systematic review was performed. MATERIALS AND METHODS: Both, Pubmed and ISI Web of Knowledge database were searched using the following keywords and MESH headings: "Endometrial cancer", "Endometrial Neoplasms", "Endometrial Neoplasms/radiotherapy", "External beam radiation therapy", "Brachytherapy" and adequate combinations. CONCLUSION: Recent data from randomized trials indicate that external beam radiation therapy - particularly in combination with extended lymph node dissection - or radical lymph node dissection increases toxicity without any improvement of overall survival rates. Thus, reduced surgical aggressiveness and limitation of radiotherapy to vaginal-vault-brachytherapy only is sufficient for most cases of early stage endometrial cancer.
