Quality of life predicts overall survival in women with platinum-resistant ovarian cancer: an AURELIA substudy.

BACKGROUND: Women with platinum-resistant ovarian cancer are a heterogeneous group whose median overall survival is 12 months. We hypothesized that their quality of life (QoL) scores would be prognostic. PATIENTS AND METHODS: Data from AURELIA (n = 326), a randomized trial of chemotherapy with or without bevacizumab, were used to identify baseline QoL domains [EORTC (European Organisation for Research and Treatment of Cancer) QLQ-C30 and OV28] that were significantly associated with overall survival in multivariable Cox regression analyses. Patients were classified as having good, medium, or poor risk. Cutpoints were validated in an independent dataset, CARTAXHY (n = 136). Multivariable analyses of significant QoL domains on survival were adjusted for clinicopathological prognostic factors. The additional QoL information was assessed using C statistic. RESULTS: In AURELIA, all domains, except cognitive function, predicted overall survival in univariable analyses. Physical function (P < 0.001) and abdominal/gastrointestinal symptom (P < 0.001) scores remained significant in multivariable models. In high (score <67), medium (67-93), and low (>93) risk categories for physical function, median overall survival was 11.0, 14.7, and 19.3 months, respectively (P < 0.001). In CARTAXHY, median overall survival was 7.9, 16.2, and 23.9 months (P < 0.001), respectively. For high- (>44), medium- (13-44), and low- (<13) risk categories for abdominal/gastrointestinal symptoms, median overall survival was 11.9, 14.3, and 19.7 months in AURELIA (P < 0.001) and 10.5, 19.6, and 24.1 months in CARTAXHY (P = 0.02). Physical function (P = 0.02) and abdominal/gastrointestinal symptoms (P = 0.03) remained independent prognostic factors after adjustment for clinicopathological factors. The C statistic of the full model was 0.71. For QoL factors alone, patient factors alone and disease factors alone, the C statistics were 0.61, 0.61, and 0.67 respectively. CONCLUSIONS: Physical function and abdominal/gastrointestinal symptom scores improved predictions of overall survival over clinicopathological factors alone in platinum-resistant ovarian cancer. This additional prognostic information could improve trial stratification, patient-doctor communication about prognosis, and clinical decision-making. CLINICAL TRIAL REGISTRATION: NCT00976911.

[Representatives of orthopaedic and trauma surgery residents in Germany]. / Assistentensprecher in Orthopädie und Unfallchirurgie in Deutschland.

In most German hospitals there are resident representatives to stand in for the rights and interests of residents. The precise number of representatives in orthopaedic and trauma surgery is unknown, as well as the field of duty and the rights of this position.The Junges Forum O&U presents survey data, which were collected from members of the German Society for Trauma Surgery (DGU), the German Society for Orthopaedics and Orthpaedic Surgery (DGOOC) and the German Society for Orthopaedics and Trauma (DGOU). All had an age below 40 years. The Survey was carried out in a period between 27th of January 2015 and 26th of March 2015.These data allowed the Junges Forum O&U to analyse the duties and numbers of representatives for residents in orthopaedic and trauma surgery in Germany. Questionnaires from 316 representatives were fully analysed. Of these, 92 % work at university hospitals. The conditions of election and the duties are not defined. The activity as representative was mainly fulfilled in spare time. The major aspect was conflict resolution between colleagues.The Junge Forum O&U presents the recommendation for election, field of duty and meetings on a regular basis with the other residents or even the first-line management.

[Evaluation of Psychiatric Disorders on the Basis of a SCID Screening]. / Evaluation psychiatrischer Störungen anhand eines erweiterten SKID-Screenings.

BACKGROUND: Psychiatric symptoms/syndromes such as depression, apathy, anxiety or psychotic episodes are present in a range of neurological disorders including Parkinson's disease. The Structured Clinical Interview for DSM-IV (SCID) represents the gold standard for the assessment of psychiatric disorders but is often too time-consuming for application in clinical practice. METHODS: 66 participants were examined using the screening items and the first two questions of section A of the SCID as well as the complete version of the SCID, part I. The accuracy of the screening and the complete SCID was evaluated, and logistic regression was conducted to analyze factors associated with measure disagreement between the two procedures. RESULTS: Overall, psychiatric disorders were identified by screening in 40/66 (60.6%), as against 31/66 (47.0%) using the complete SCID. Compared to the complete SCID, the sensitivity and specificity of the screening items were 88% and 59%, respectively. CONCLUSION: Based on its good sensitivity, the SCID screening may be used in clinical practice to yield an overview of psychiatric disorders that may require treatment. Due to its moderate specificity, however, the complete version of the SCID should be subsequently used in cases whenever the SCID screening is positive. In any case, the SCID screening must be regarded as inadequate for the detection of psychotic symptoms.

Decision-making about corticosteroids in relapses of multiple sclerosis - development of a questionnaire based on the theory of planned behaviour.

BACKGROUND: Relapses of multiple sclerosis are burdensome events and entail potentially lasting loss of function. People with multiple sclerosis have to consider corticosteroids, providing limited benefits and the risk of adverse effects. OBJECTIVE: To develop and validate a questionnaire investigating the internal process of people with multiple sclerosis making decisions about corticosteroids. METHODS: The questionnaire is structured by three domains, attitude, subjective social norm, and perceived behavioural control, which according to the theory of planned behaviour determine action planning. The development is inspired by a previous questionnaire studying decisions on immunotherapy. The questionnaire was tested in qualitative think-aloud interviews (n=10) for feasibility and comprehensibility and in an online survey (n=203) to assess construct and criterion validity. RESULTS: The 18-item questionnaire was considered feasible and comprehensible. It predicted the intention to receive corticosteroids in up to 82.3% of cases. "Subjective social norm" impacted most on intention. The questionnaire also proved sensitive for autonomy preferences of people with multiple sclerosis. CONCLUSION: This study shows that the questionnaire appropriately explains the internal process people with multiple sclerosis run through when considering corticosteroids. It can be used to inform developments of tailored support for people with multiple sclerosis in making informed decisions about relapse management.

Structure of membrane surfactant and liquid crystalline smectic lamellar phases under flow.

Synchrotron x-ray scattering studies were performed to probe the nonequilibrium structures of two layered systems at high shear rates: the smectic-A phase of the thermotropic liquid crystal 4-cyano-4'-octylbiphenyl (8CB) and the lamellar L(alpha) phases of surfactant membranes composed of sodium dodecyl sulfate and pentanol. Whereas the lamellar surfactant phases oriented primarily with their layers parallel to the shearing plates, as expected intuitively, in the corresponding high shear regime, the smectic-A liquid crystalline material oriented with the layers perpendicular to the shearing plates. A careful numerical study revealed that this surprising layer orientation results from nonlinear dynamics of the liquid crystal director and is caused by the flow distortion of thermal fluctuations.

Development of insulin resistance in the JCR:LA-cp rat: role of triacylglycerols and effects of MEDICA 16.

The JCR:LA-cp rat develops an extreme obese/insulin-resistant syndrome such that by 12 weeks of age, there is no longer any insulin-mediated glucose turnover. At 4 weeks of age, obese and lean rats have essentially identical basal and insulin-mediated glucose uptake in skeletal muscle. By 8 weeks of age, however, the obese rats no longer exhibit such intake. Plasma insulin concentrations in the normal fed state show only small increases up to 4 weeks, with a rapid rise to a marked hyperinsulinemia thereafter, with an age at half-development of 5.5 weeks. Plasma triacylglycerol concentrations in fed obese rats are elevated at 3 weeks and rise rapidly thereafter. The triacylglycerol content of skeletal muscle is significantly elevated in the obese rats at 4 weeks of age. Histological examination of Oil Red O-stained muscle tissue and transmission electron microscopy shows the presence of intracellular lipid droplets. Treatment with the potent triacylglycerol-lowering agent MEDICA 16 (beta,beta'-tetramethylhexadecanedioic acid) from 6 weeks of age reduces plasma lipids markedly, but it reduces body weight and insulin resistance only modestly. In contrast, treatment with MEDICA 16 from the time of weaning at 3 weeks of age results in the normalization of food intake and body weight to over 8 weeks of age. The development of hyperinsulinemia is also delayed until 8.5 weeks of age, and insulin levels remain strongly reduced. Plasma triacylglycerol concentrations remain at the same level as in lean rats, and neither an elevated muscle triacylglycerol content nor intracellular lipid droplets are found at 4 weeks of age. The results indicate that insulin resistance develops in the young animals and is not directly due to a genetically determined defect in insulin metabolism. The mechanism of induction instead appears to be related to an exaggerated triacylglycerol metabolism.

Effect of castration on hyperlipidemic, insulin resistant JCR:LA-corpulent rats.

The JCR:LA-cp rat exhibits an obese, insulin resistant, hyperlipidemic syndrome. Obese male rats, only, develop atherosclerosis and ischemic myocardial lesions. The obese males have a greater hyperinsulinemia, but the obese females have a much greater hypertriglyceridemia due to hypersecretion of very low density lipoprotein (VLDL). Obese rats of both sexes were surgically castrated at 6 weeks of age to study the influence of testosterone and estrogen secretion on the sexual dimorphism of metabolism and disease in this strain. Castration had no effect on body weight or food consumption up to 16 weeks of age. Castrated male rats had significantly improved glucose tolerance, but a doubled serum triglyceride concentration. Castrated female rats showed approximately halved triglyceride levels. The distribution of the triglyceride molecular species was altered in the castrated male rats to resemble that of the females in which there was no change with castration. The effects suggest that testosterone may inhibit hepatic triglyceride secretion and promotes insulin insensitivity. Estrogen appears to exacerbate hepatic hypersecretion of VLDL. Castration had no effect on myocardial lesion frequency in 9-month-old rats of either sex. This implies that estrogen does not exert a direct protective effect against cardiovascular disease in this animal model.

Impact of BRCA1 testing on women with cancer: a pilot study.

We sought to understand better the impact of genetic testing and counseling in a group of women who had early breast cancer (age <50) or ovarian cancer and a family history of cancer. Thirty-five women underwent genetic counseling and genetic testing for BRCA1/2 at the University of Colorado Cancer Center, Hereditary Cancer Clinic. Psychological assessment (IES and Hopkins Symptom Checklist) was made before counseling, and 1 month after genetic test results were reported to women. A statistically significant decrease in anxiety was evidenced 1 month after results were given (p = 0.024). Decreased intrusive thoughts related to genetic testing were seen only for those testing negative (p = 0.0003). Women diagnosed with cancer less than 1 year prior to genetic testing experienced the greatest cancer-specific distress (p = 0.01) and distress related to genetic testing (p = not significant). Satisfaction with the counseling and testing process was high. In conclusion, genetic testing and counseling can occur with little anxiety and stress. However, women less than 1 year from a cancer diagnosis will experience the greatest distress associated with genetic testing and counseling. Women who are considering genetic testing and counseling close to a diagnosis of cancer may require greater psychological support.

Quality of life in patients receiving treatment for gynecologic malignancies: special considerations for patient care.

Advances in the treatment of gynecologic cancer have extended the duration of survival of many patients. However, these patients frequently experience a variety of treatment- and disease-related side effects that diminish their quality of life (QOL) during and after treatment; among these are pain, nausea and vomiting, anemia, fatigue, peripheral neuropathy, emotional distress, and sexual dysfunction. Given the gains in survival time, patient care is being expanded to include enhancement or preservation of QOL in addition to early diagnosis and disease treatment, thus treating the whole person. In parallel with this evolution in cancer care, supportive measures are being increasingly recognized as crucial to effective patient management. This paper reviews some of the potential causes of diminished QOL in gynecologic cancer patients and basic treatment strategies for their control, with a focus on short-term QOL issues. It is important that clinicians monitor QOL during the course of the disease and its treatment, utilize procedures and therapeutic agents that take patient preferences and QOL into account, and proactively prevent and treat relevant symptoms.

Psychological, social and sexual effects of gestational trophoblastic disease on patients and their partners.

The psychological, social and sexual effects of gestational trophoblastic disease in both patients and their partners are reviewed. The results suggest that despite the favorable prognosis of this disease, mood disturbances, sexual disturbances and fertility concerns can persist in both patients and their partners. Recommendations are made concerning providing supportive care to meet the needs of patients and their partners.

Portfolio: authentic assessment in the age of the curriculum revolution.

This article provides an extensive review of the literature on portfolio use in education. There is a gap in the literature related to portfolio use in nursing education. Portfolios are one method of authentic assessment, showing evidence of student growth and achievement over time. Development of the student portfolio promotes collaboration between student and faculty. The Integrated Proficiency-Criterion (IPC) framework is one proposed method for portfolio development and evaluation, using Benner's stages of proficiency and NLN criteria for accreditation of baccalaureate nursing programs.
