    <p>Abstract</p> <p>Background</p> <p>There is strong evidence to suggest that multiple work-related health problems are preceded by a higher need for recovery. Physical activity and relaxation are helpful in decreasing the need for recovery. This article aims to describe (1) the development and (2) the design of the evaluation of a daily physical activity and relaxation intervention to reduce the need for recovery in office employees.</p> <p>Methods/Design</p> <p>The study population will consist of employees of a Dutch financial service provider. The intervention was systematically developed, based on parts of the Intervention Mapping (IM) protocol. Assessment of employees needs was done by combining results of face-to-face interviews, a questionnaire and focus group interviews. A set of theoretical methods and practical strategies were selected which resulted in an intervention program consisting of Group Motivational Interviewing (GMI) supported by a social media platform, and environmental modifications. The Be Active & Relax program will be evaluated in a modified 2 X 2 factorial design. The environmental modifications will be pre-stratified and GMI will be randomised on department level. The program will be evaluated, using 4 arms: (1) GMI and environmental modifications; (2) environmental modifications; (3) GMI; (4) no intervention (control group). Questionnaire data on the primary outcome (need for recovery) and secondary outcomes (daily physical activity, sedentary behaviour, relaxation/detachment, work- and health-related factors) will be gathered at baseline (T0), at 6 months (T1), and at 12 months (T2) follow-up. In addition, an economic and a process evaluation will be performed.</p> <p>Discussion</p> <p>Reducing the need for recovery is hypothesized to be beneficial for employees, employers and society. It is assumed that there will be a reduction in need for recovery after 6 months and 12 months in the intervention group, compared to the control group. Results are expected in 2013.</p> <p>Trial registration</p> <p>Netherlands Trial Register (NTR): NTR2553</p

    Objective In medullary thyroid cancer (MTC) age is considered an important prognostic factor but survival has never been properly adjusted for baseline mortality in the general population. We aimed to identify prognostic factors by analysing patients with MTC regarding life expectancy. Design We described a retrospective cohort study with a median follow-up of 8 years (range 1-35 years). Patients We included 120 consecutive patients of whom 66 (55%) had sporadic MTC. Male/female ratio was 1 : 1; median age was 45 years (range 3-83 years). Measurements Measurements were overall and disease-specific survival and life expectancy expressed as survival adjusted for baseline mortality rate in the general population. Results Overall and disease-specific 10-year survival was 65% and 73%, respectively. After 10 years, 29% of patients were biochemically and 63% clinically cured. Median overall life expectancy was 0.58 (95%CI 0.37-0.80). Detectable recurrence occurred in 60 patients after a median of 36 months (range 5-518 months). On multivariate regression analysis only stage of disease and extrathyroidal extension predicted recurrence-free life expectancy. Extrathyroidal extension was the only independent predictor of overall life expectancy. Persistent biochemical MTC did not independently affect life expectancy but calcitonin doubling time of less than one year indicated worse prognosis. Patients without detectable recurrences after initial treatment had a life expectancy similar to the general population. Conclusions In MTC patients, extrathyroidal extension and stage at diagnosis are the only independent predictors of (recurrence-free) life expectancy. Patients diagnosed in an early stage of disease and patients without detectable recurrence have favourable life expectancy independently of biochemical cure

    BACKGROUND: Circulating vascular endothelial growth factor (VEGF) was studied as a substitute endpoint for treatment response after VEGF plasmid therapy. The effect of coronary artery bypass surgery (CABG) with cardiopulmonary bypass (CPB) on systemic VEGF levels are however largely unknown, therefore, we studied the effect of this procedure to measure VEGF levels after surgery alone. METHODS: Fourteen patients requiring CABG were included. VEGF165 levels, ischemic markers, and hematology were measured before, directly after six days after surgery. RESULTS: VEGF165 in serum and whole blood levels were increased up to six days after CABG, respectively 249.6(plus or minus)50.4 to 451.7(plus or minus)56.4 (day 6) and 581.9(plus or minus)105.1 to 783.4(plus or minus)97.7 (day six). There was a close correlation of circulating VEGF165 with leukocyte counts and platelets and not with ischemic markers. CONCLUSION: Following surgery and in case of activated leukocyte and platelet counts care must be taken in the interpretation of systemic VEGF165 levels. (copyright) 2006 Taylor & Franci

    Early FDG-PET assessment in combination with clinical risk scores determines prognosis in recurring lymphoma

    This study was set up to demonstrate whether prognostic classification based on the secondary age-adjusted International Prognostic Index (sAA-IPI) for recurring aggressive non-Hodgkin lymphoma (NHL) or the prognostic score for recurring Hodgkin lymphoma (HL) can be improved by including the midtreatment results of fluorine-18-fluorodeoxy-glucose-positron emission tomography (FDG-PET). Clinical data on patients with recurring lymphoma who were treated with second-line chemotherapy (DHAP-VIM-DHAP) followed by autologous stem cell transplantation (ASCT) were collected and combined with the results of FDG-PET performed before and after 2 cycles of reinduction chemotherapy. PET responses after 2 courses were scored as complete remission (CR), partial remission (PR), or no response (NR). A multivariate analysis was performed to design a predictive model. The number of patients (101 of 117) included those (78 patients with aggressive NHL and 23 patients with HL) that could be analyzed according to protocol. Of these, 80 patients were chemosensitive and 77 received transplants. Both secondary clinical risk score (P<.001) and FDG-PET response (P<.001) were independent predictive factors for the total evaluable group of patients with lymphoma and for patients with NHL alone. The combined use of the clinical risk score and FDG-PET response after 2 chemotherapy courses identified at least 4 categories of patients with a failure-free survival varying between 5% to 100% after transplantation (P<.001). These data indicate that the secondary clinical risk score in conjunction with FDG-PET response provides a more accurate prognostic instrument for the outcome of second-line treatment at least in patients with recurring NHL

    Functional annotation of heart enriched mitochondrial genes GBAS and CHCHD10 through guilt by association

    Despite the mitochondria ubiquitous nature many of their components display divergences in their expression profile across different tissues. Using the bioinformatics-approach of guilt by association (GBA) we exploited these variations to predict the function of two so far poorly annotated genes: Coiled-coil-helix-coiled-coil-helix domain containing 10 (CHCHD10) and glioblastoma amplified sequence (GBAS). We predicted both genes to be involved in oxidative phosphorylation. Through in vitro experiments using gene-knockdown we could indeed confirm this and furthermore we asserted CHCHD 10 to play a role in complex IV activity

    Objective: To compare the semen quality and hormonal status between patients with testicular cancer and normal versus increased serum levels of beta-hCG. Design: Retrospective study. Setting: Academic research environment. Patient(s): All 203 patients with testicular cancer who required chemotherapy in the period 1995-2003 were included. Intervention(s): In 107 patients semen samples were stored by cryopreservation; 62 patients could be analyzed because both semen was stored and hormones were determined before starting chemotherapy (median age 25 years, range 17-49 years). Main Outcome Measure(s): Total motile sperm count, T, E(2), LH, FSH, and PRL. Result(s): Total motile sperm count was decreased in patients with increased beta-hCG (median 11.9 x 10(6)) compared with patients with normal beta-hCG (median 21.5 x 10(6)). Testosterone, E(2), and PRL were significantly higher in patients with increased beta-hCG levels, whereas LH and FSH were lower. Semen quality was significantly and negatively correlated with beta-hCG, E(2), and PRL. Conclusion(s): Patients with increased beta-hCG had an inferior spermatogenesis compared with patients with normal beta-hCG. Increased beta-hCG appears to be associated with impaired spermatogenesis and increased levels of E(2) and PRL. (Fertil Steril (R) 2009;91:2481-6.

    \u3cp\u3eBACKGROUND: Thyroid nodules are very common in general medical practice, but rarely turn out to be a medullary thyroid carcinoma (MTC). Calcitonin is a sensitive tumour marker for the detection of MTC (basal calcitonin). Sometimes a stimulation test is used to improve specificity (stimulated calcitonin). Although the European Thyroid Association's guideline advocates calcitonin determination in people with thyroid nodules, the role of routine calcitonin testing in individuals with thyroid nodules is still questionable. OBJECTIVES: The objective of this review was to determine the diagnostic accuracy of basal and/or stimulated calcitonin as a triage or add-on test for detection of MTC in people with thyroid nodules. SEARCH METHODS: We searched CENTRAL, MEDLINE, Embase and Web of Science from inception to June 2018. SELECTION CRITERIA: We included all retrospective and prospective cohort studies in which all participants with thyroid nodules had undergone determination of basal calcitonin levels (and stimulated calcitonin, if performed). DATA COLLECTION AND ANALYSIS: Two review authors independently scanned all retrieved records. We extracted data using a standard data extraction form. We assessed risk of bias and applicability using the QUADAS-2 tool. Using the hierarchical summary receiver operating characteristic (HSROC) model, we estimated summary curves across different thresholds and also obtained summary estimates of sensitivity and specificity at a common threshold when possible. MAIN RESULTS: In 16 studies, we identified 72,368 participants with nodular thyroid disease in whom routinely calcitonin testing was performed. All included studies performed the calcitonin test as a triage test. Median prevalence of MTC was 0.32%. Sensitivity in these studies ranged between 83% and 100% and specificity ranged between 94% and 100%. An important limitation in 15 of the 16 studies (94%) was the absence of adequate reference standards and follow-up in calcitonin-negative participants. This resulted in a high risk of bias with regard to flow and timing in the methodological quality assessment. At the median specificity of 96.6% from the included studies, the estimated sensitivity (95% confidence interval (CI)) from the summary curve was 99.7% ( 68.8% to 100%). For the median prevalence of MTC of 0.23%, the positive predictive value (PPV) for basal calcitonin testing at a threshold of 10 pg/mL was 7.7% (4.9% to 12.1%). Summary estimates of sensitivity and specificity for the threshold of 10 pg/mL of basal calcitonin testing was 100% (95% CI 99.7 to 100) and 97.2% (95% CI 95.9 to 98.6), respectively. For combined basal and stimulated calcitonin testing, sensitivity ranged between 82% and 100% with specificity between 99% and 100%. The median specificity was 99.8% with an estimated sensitivity of 98.8% (95% CI 65.8 to 100) . AUTHORS' CONCLUSIONS: Both basal and combined basal and stimulated calcitonin testing have a high sensitivity and specificity. However, this may be an overestimation due to high risk of bias in the use and choice of reference standard The value of routine testing in patients with thyroid nodules remains questionable, due to the low prevalence, which results in a low PPV of basal calcitonin testing. Whether routine calcitonin testing improves prognosis in MTC patients remains unclear.\u3c/p\u3

    Background. Extent of neck dissection is controversial in patients with palpable medullary thyroid cancer (MTC). Methods. We evaluated 64 MTC patients (19 hereditary, 45 sporadic) with palpable thyroid nodules (group 1, n = 35) or palpable lymph node metastases (group 2, In = 29). Standard surgery included total thyroidectomy, central compartment dissection, and additional neck dissection on indication. Results. In group 1, 40% of the patients were cured. Thirty-one percent of all patients had central, 23% ipsilateral, 14% contralateral, and 14% mediastinal, metastases. Fifty-one percent developed locoregional recurrence. Locoregional recurrence (p =.043) and reoperations (p =.020) were noted more often after a less than standard initial procedure, In group 2, no patients were cured, All had central, 93% ipsilateral, 45% contralateral, and 52% mediastinal metastases. Thirty-eight percent developed locoregional recurrence. Conclusions. Locoregional recurrence frequently occurs in palpable MTC, and tumor control may be improved by standard central, bilateral, and upper mediastinal neck dissection. (c) 2007 Wiley Periodicals, Inc
