Complications,risk factors,and patients-reported outcomes after skin-sparing mastectomy followed by breast reconstruction in women with BRCA mutations

Background: Women with a BRCA mutation have the option of undergoing prophylactic mastectomy and immediate breast reconstruction; however, the potential negative effects of reconstruction on women’s physical and psychological well-being are unclear. This study aimed to investigate complications, patient-reported pain, health-related quality-of-life (HRQoL) and satisfaction following reconstructive surgery at Oslo University Hospital between 2006 and 2013.

Methods: Data were collected retrospectively from the records of 238 patients. A cross-sectional survey was conducted to collect patient-reported HRQoL and satisfaction with outcome using the Short Form-12 questionnaires and Breast-Q. The self-administered Leeds assessment of neuropathic symptoms and signs was used to assess neuropathic pain.

Results: The majority of participants (89.5%) underwent implant-based breast reconstruction (IBBR); the remainder underwent autologous-tissue breast reconstruction (ATBR). Overall, 28.6% had complications within 30?days of surgery and 14.6% required resurgery because of complications. Women who underwent IBBR had a later onset of complications than those undergoing ATBR. Participants in the survey (n?=?175 of 219, response rate 79.9%) reported similar HRQoL to an age-matched general female population. Few (2.9%) reported neuropathic pain. Patients who underwent IBBR were significantly less satisfied with the reconstructed breast (p?=?.001) and overall outcome (p?=?.02) than those who underwent ATBR, but there were no significant differences in HRQoL scores between the two groups.

Conclusions: Overall, 28.6% of the women had complications within 30?days and 14.6% needed resurgery. Few had neuropathic pain. Women who underwent ATBR were more satisfied with the overall outcome than those who underwent IBBR.     

Reduced mortality in treating acutely sick,frail older patients in a geriatric evaluation and management unit. A prospective randomized trial

OBJECTIVES: Documentation of treatment effects in acutely sick frail older patients in geriatric evaluation and management units (GEMUs) is scarce. The present study evaluated whether treatment in a GEMU would reduce mortality as compared to traditional treatment delivered in the Department of Internal Medicine. DESIGN: Prospective randomized trial. SETTING: GEMU or general medical ward. PARTICIPANTS: Acutely sick frail patients aged 75 and older who had been admitted to the Department of Internal Medicine were randomly assigned to treatment in the GEMU (n = 127) or to the general medical wards (n = 127). The following inclusion criteria were used to target frail patients: chronic disability, acute impairment of single activity of daily living, mild/moderate dementia, confusion, depression, imbalance/dizziness, falls, impaired mobility, urinary incontinence, malnutrition, polypharmacy, vision or hearing impairment, social problems, or prolonged bedrest. INTERVENTION: In the GEMU, the treatment strategy emphasized interdisciplinary assessment of all relevant disorders, prevention of complications and iatrogenic conditions, early mobilization/rehabilitation, and comprehensive discharge planning. The control group received treatment as usual from the Department of Internal Medicine. After discharge neither group received specific follow-up. MEASUREMENTS: Mortality and causes of death. RESULTS: Mortality in the intervention and control groups, respectively, was 12% and 27% at 3 months (P =.004), 16% and 29% (P =.02) at 6 months, and 28% and 34% (P =.06) at 12 months. The hazard ratio was 0.39 (95% confidence interval = 0.21-0.72) at 3 months. The main cause of death was cardiovascular disease. CONCLUSION: Treatment of acutely sick, frail, older patients in a GEMU substantially reduced mortality.     

C2 monitoring in maintenance renal transplant recipients: is it worthwhile?

Presently, there is little knowledge regarding cyclosporine (CsA) concentration at 2 hr post-dose (C2) monitoring in maintenance patients. This study evaluates the actual C2 range in stable renal transplant recipients (who underwent transplantation >12 months ago). In addition, we investigated whether underexposure or overexposure to CsA (assessed by C2) affects graft function (as measured by serum [S]-creatinine). All renal transplant recipients in Norway receiving CsA were asked to participate; 1447 fulfilled the criteria. Valid C2 and CsA trough concentration (C0) measurements were performed in 1032 renal transplant recipients (71%) monitored by C0. Target C0 level was 75 to 125 mumol/L. CsA levels were measured using a Cloned Enzyme Donor Immunoassay method, and all analyses were performed in the same laboratory (overall mean [+/-standard deviation] CsA C0=112+/-31 mug/L, CsA C2=697+/-211 mug/L [range 81-1580 mug/L], CsA dose [mg/day]=208+/-61, CsA dose [mg/kg/day]=2.8+/-1.1, and S-creatinine=141+/-58 mumol/L). A univariate analysis of variance showed that patients with C2 levels between 700 and 800 mug/L (n=203, S-creatinine=136+/-49 mumol/L) had significantly lower S-creatinine levels compared with patients with C2 levels greater than 950 mug/L (n=94, S-creatinine=152+/-56 mumol/L) (P<0.02). The same was true for patients with C2 levels less than 450 mug/L (n=95, S-creatinine 141+/-72 mumol/L) (P<0.05) when compared with patients with C2 levels greater than 950 mug/L. There was no significant difference in S-creatinine between patients in the low and intermediate C2 group; 666 patients had C0 levels in the therapeutic range (75-125 mumol/L). A linear regression showed a significant relation between S-creatinine and C2 for these patients (P=0.03). The corresponding relation between S-creatinine and C0 was nonsignificant (P=0.3). Monitoring of C2 in maintenance patients is a valuable tool to detect overexposure to CsA. Until results from prospective studies are available, we recommend C0 in the therapeutic range and reduction in CsA in overexposed patients, aiming at a C2 value between 700 and 800 mug/L.     

The effect of experimenter gender on autonomic and subjective responses to pain stimuli

Several studies have shown that male subjects report lower pain intensity to female compared to male experimenters. The present experiment examined whether experimenter gender also modulated autonomic pain responses. Sixty-four students (32 females) participated in a 2 Subject gender x 2 Experimenter gender x 15 Pain Tests mixed design. Six experimenters, three females and three males collected data. Heat pain was +48 degrees C induced to the right volar forearm. Subjective measurements consisted of pain intensity, pain unpleasantness, stress, arousal and mood. Autonomic responses were heart rate variability and skin conductance levels. The results revealed significant interactions between experimenter gender and subject gender on pain intensity and arousal, but there were no interactions in the physiological data. In conclusion, the lower pain report in male subjects to female experimenters is not mediated by changes in autonomic parameters, and the effect of experimenter gender is probably due to psychosocial factors.     

Sensitivity of regression calibration to non‐perfect validation data with application to the Norwegian Women and Cancer Study

Measurement error occurs when we observe error‐prone surrogates, rather than true values. It is common in observational studies and especially so in epidemiology, in nutritional epidemiology in particular. Correcting for measurement error has become common, and regression calibration is the most popular way to account for measurement error in continuous covariates. We consider its use in the context where there are validation data, which are used to calibrate the true values given the observed covariates. We allow for the case that the true value itself may not be observed in the validation data, but instead, a so‐called reference measure is observed. The regression calibration method relies on certain assumptions.This paper examines possible biases in regression calibration estimators when some of these assumptions are violated. More specifically, we allow for the fact that (i) the reference measure may not necessarily be an ‘alloyed gold standard’ (i.e., unbiased) for the true value; (ii) there may be correlated random subject effects contributing to the surrogate and reference measures in the validation data; and (iii) the calibration model itself may not be the same in the validation study as in the main study; that is, it is not transportable. We expand on previous work to provide a general result, which characterizes potential bias in the regression calibration estimators as a result of any combination of the violations aforementioned. We then illustrate some of the general results with data from the Norwegian Women and Cancer Study. Copyright © 2015 John Wiley & Sons, Ltd.     

“Sometimes it’s a bit too much Disney”: exploring Norwegian parents and their ambiguous domestication of Disney

Parents are often ambivalent about their children’s engagement with popular culture, where popular culture is seen as trivial and potentially harmful. In this article, I explore how Norwegian parents of girls experienced the Disney tween shows, and tied in merchandise of Hannah Montana and High School Musical. As the parents interviewed reported feeling ambivalent and conflicted about the Disney shows, the article makes use of Bakhtin’s dialogism and domestication theory to explore this ambivalence. Employing the concept of voice from Bakhtin, the interview data suggest five voices the parents drew on – the educational voice, the voice of children’s autonomy, Disney as innocent and safe, the voice of caring consumption and the culture critical voice. The analysis focuses on how these voices operated, how they were expressed in the interviews, and what these different voices produced in terms of how Disney was included in the everyday home life.
