Perioperative sexual interest in women with suspected gynecologic malignancies

Objectives For women with gynecologic cancer, the impact of surgery on sexual interest and desire in the immediate and later postoperative period is not well characterized. The objective of this study was to report the perioperative trends of changing sexual interest and desire in a cohort of women undergoing surgery for suspected gynecologic malignancies. Methods This is an ancillary analysis of a cohort study analyzing health-related outcomes in women who underwent primary surgical management of a suspected gynecologic malignancy between 10/2013 and 10/2014. Subjects completed the Patient-Reported Outcomes Measurement Information System Sexual Function and Satisfaction Questionnaire (PROMIS-SFQ) preoperatively and questions on sexual interest and desire at one, three, and six months postoperatively. Bivariate tests and multiple linear regression were used to analyze data. Results Of 231 women who completed a baseline PROMIS-SFQ, 187 (81%) completed one-month, 170 (74%) three-month, and 174 (75%) six-month follow-up interviews. Following surgery, 71% of enrolled subjects were diagnosed with a malignancy. Women age 55 (− 5.5 ± 1.0 vs − 2.3 ± 0.9, p = 0.02). In a multivariable analysis, age < 55 remained associated with a larger decrease in sexual interest at one month postoperatively (− 4.6, 95% CI: − 1.8, − 7.4), as did having cancer vs benign disease for women of all ages (− 5.6, 95% CI: − 9.6, − 1.5). Conclusions This study provides new data regarding the timing and magnitude of changes in sexual interest following gynecologic oncology procedures

Sexual Health before Treatment in Women with Suspected Gynecologic Malignancy

Objectives: Sexual health in survivors of gynecologic cancer has been studied; however, sexual health in these women before treatment has not been thoroughly evaluated. The objective of our study was to describe the pretreatment characteristics of sexual health of women with suspected gynecologic cancer before cancer treatment. Materials and Methods: We performed a cross-sectional analysis of women with a suspected gynecologic cancer, who were prospectively enrolled in a hospital-based cancer survivorship cohort from August 2012 to June 2013. Subjects completed the validated Patient-Reported Outcomes Measurement Information System Sexual Function and Satisfaction Questionnaire. Pretreatment sexual health was assessed in terms of sexual interest, desire, lubrication, discomfort, orgasm, enjoyment, and satisfaction. Results: Of 186 eligible women with suspected gynecologic cancer, 154 (82%) completed the questionnaire pretreatment. Mean age was 58.1 ± 13.3 years. Sexual health was poor: 68.3% reported no sexual activity, and 54.7% had no interest in sexual activity. When comparing our study population to the general U.S. population, the mean pretreatment scores for the subdomains of lubrication and vaginal discomfort were similar, while sexual interest was significantly lower and global satisfaction was higher. In a linear regression model, controlling for cancer site, age remained significantly associated with sexual function while cancer site did not. Conclusions: Problems with sexual health are prevalent in women with suspected gynecologic malignancies before cancer treatment. Increasing awareness of the importance of sexual health in this population will improve quality of life for these women

Gynecologic cancer outcomes in the elderly poor: A population-based study

BACKGROUND Adults aged ≥65 years who are dually enrolled in Medicare and Medicaid are an at-risk group in health care. However, to the best of the authors' knowledge, the outcomes of women with gynecologic cancers in this population are unknown. METHODS The current study was a population-based cohort study of North Carolina state cancer registry cases of uterine, ovarian, cervical, and vulvar/vaginal cancers (2003-2009), with linked enrollment in Medicare and state Medicaid. Outcomes of all-cause mortality and stage of disease at the time of diagnosis were analyzed as a function of enrollment status using multivariate analysis and survival curves. RESULTS Of 4522 women aged ≥65 years (3702 of whom were enrolled in Medicare [82%] and 820 of whom were dually enrolled [18%]), there were 2286 cases of uterine (51%), 1587 cases of ovarian (35%), 302 cases of cervical (7%), and 347 cases of vulvar/vaginal (8%) cancers. Dual enrollees had increased all-cause mortality overall (adjusted hazard ratio [aHR], 1.34; 95% confidence interval [95% CI], 1.19-1.49), and within each cancer site (uterine: aHR, 1.22 [95% CI, 1.02-1.47]; ovarian: aHR, 1.25 [95% CI, 1.05-1.49]; cervical: aHR, 1.34 [95% CI, 0.96-1.87]; and vulvar/vaginal: aHR, 1.93 [95% CI, 1.36-2.72]). Increased odds of advanced-stage disease at the time of diagnosis among dual enrollees was only present in patients with uterine cancer (adjusted odds ratio, 1.38; 95% CI, 1.06-1.79). Stratified survival curves demonstrated the strongest disparities among women with early-stage uterine and early-stage vulvar/vaginal cancers. CONCLUSIONS Women aged ≥65 years who were dually enrolled in Medicare and Medicaid were found to have an overall 34% increase in all-cause mortality after diagnosis with a gynecologic cancer compared with the non-dually enrolled Medicare population. Women with early-stage uterine and vulvar/vaginal cancers appeared to have the most disparate outcomes. Because these malignancies are generally curable, they have the most potential for benefit from targeted interventions

Preoperative quality of life and surgical outcomes in gynecologic oncology patients: A new predictor of operative risk?

Quality of life (QoL) for women with gynecologic malignancies is predictive of chemotherapy related toxicity and overall survival but has not been studied in relation to surgical outcomes and hospital readmissions. Our goal was to evaluate the association between baseline, pre-operative QoL measures and 30-day post-operative morbidity and health resource utilization by gynecologic oncology patients

Creation and manipulation of entanglement in spin chains far from equilibrium

We investigate creation, manipulation, and steering of entanglement in spin chains from the viewpoint of quantum communication between distant parties. We demonstrate how global parametric driving of the spin-spin coupling and/or local time-dependent Zeeman fields produce a large amount of entanglement between the first and the last spin of the chain. This occurs whenever the driving frequency meets a resonance condition, identified as "entanglement resonance". Our approach marks a promising step towards an efficient quantum state transfer or teleportation in solid state system. Following the reasoning of Zueco et al. [1], we propose generation and routing of multipartite entangled states by use of symmetric tree-like structures of spin chains. Furthermore, we study the effect of decoherence on the resulting spin entanglement between the corresponding terminal spins.Comment: 10 pages, 8 figure

Obesity is associated with worse quality of life in women with gynecologic malignancies: An opportunity to improve patient-centered outcomes

BACKGROUND: The objective of the current study was to evaluate the effect of obesity on pretreatment quality of life (QoL) in gynecologic oncology patients. METHODS: The authors analyzed collected data from an institution-wide cohort study of women with gynecologic cancers enrolled from August 2012 to June 2013. The Functional Assessment of Cancer Therapy-General, site-specific symptom scales, and the National Institutes of Health Patient-Reported Outcomes Measurement Information System (PROMIS) global mental and physical health tools were administered. Survey results were linked to clinical data abstracted from medical records (demographics and comorbid conditions). Bivariate tests and multivariate linear regression models were used to evaluate factors associated with QoL scores. RESULTS: A total of 182 women with ovarian, uterine, cervical, and vulvar/vaginal cancers were identified; of these, 152 (84%) were assessed before surgery. Mean body mass index was 33.5 kg/m2 and race included white (120 patients [79%]), black (22 patients [15%]), and other (10 patients [6.5%]). A total of 98 patients (64.5%) were obese (body mass index ≥30). On multivariate analysis, subscales for functional (17 vs 19; P=.04), emotional (16 vs 19; P=.008), and social (22 vs 24; P=.02) well-being as well as overall Functional Assessment of Cancer Therapy-General scores (77 vs 86; P5.002) and Patient-Reported Outcomes Measurement Information System global physical health scores (45 vs 49; P=.003) were found to be significantly lower in obese versus nonobese patients. CONCLUSIONS: Before cancer treatment, obese patients with gynecologic malignancies appear to have worse baseline QoL than their normal-weight counterparts. Emerging models of QoL-based cancer outcome measures may disproportionately affect populations with a high obesity burden. The potential disparate impact of cancer therapy on longitudinal QoL in the obese versus nonobese patients needs to be evaluated

Dogslife: a cohort study of Labrador retrievers in the UK

AbstractStudies of animals that visit primary and secondary veterinary centres dominate companion animal epidemiology. Dogslife is a research initiative that collects data directly from owners about the health and lifestyle of Kennel Club (KC) registered Labrador Retrievers (LR) in the UK. The ultimate aim is to seek associations between canine lifestyle and health. A selection of data from Dogslife regarding the height, weight and lifestyle of 4307 LR up to four years of age is reported here.The majority of the dogs were household pets, living with at least one other pet, in families or households with more than one adult. The dogs typically ate diets of dried food and daily meal frequency decreased as the dogs aged. Working dogs spent more time exercising than pets, and dogs in Wales and Scotland were exercised more than their counterparts in England. Dogs in households with children spent less time exercising than dogs in other types of households. There was considerable variation in height and weight measurements indicative of a highly heterogeneous population. The average male height at the shoulders was 2–3cm taller than the UK breed standard. Dog weights continued to increase between one and four years of age. Those with chocolate coloured coats were heavier than their yellow and black counterparts. Greater dog weight was also associated with dogs whose owners reported restricting their dog’s exercise due to where they lived.These findings highlight the utility of wide public engagement in the collation of phenotypic measures, providing a unique insight into the physical development and lifestyle of a cohort of LRs. In combination with concurrently collected data on the health of the cohort, phenotypic data from the Dogslife Project will contribute to understanding the relationship between dog lifestyle and health

Quantitative Treatment of Decoherence

We outline different approaches to define and quantify decoherence. We argue that a measure based on a properly defined norm of deviation of the density matrix is appropriate for quantifying decoherence in quantum registers. For a semiconductor double quantum dot qubit, evaluation of this measure is reviewed. For a general class of decoherence processes, including those occurring in semiconductor qubits, we argue that this measure is additive: It scales linearly with the number of qubits.Comment: Revised version, 26 pages, in LaTeX, 3 EPS figure
