Empowering employees with chronic diseases; development of an intervention aimed at job retention and design of a randomised controlled trial

<p>Abstract</p> <p>Background</p> <p>Persons with a chronic disease are less often employed than healthy persons. If employed, many of them experience problems at work. Therefore, we developed a training programme aimed at job retention. The objective of this paper is to describe this intervention and to present the design of a study to evaluate its effectiveness.</p> <p>Development and description of intervention</p> <p>A systematic review, a needs assessment and discussions with Dutch experts led to a pilot group training, tested in a pilot study. The evaluation resulted in the development of a seven-session group training combined with three individual counselling sessions. The training is based on an empowerment perspective that aims to help individuals enhance knowledge, skills and self-awareness. These advances are deemed necessary for problem solving in three stages: exploration and clarification of work related problems, communication at the workplace, and development and implementation of solutions. Seven themes are discussed and practised in the group sessions: 1) Consequences of a chronic disease in the workplace, 2) Insight into feelings and thoughts about having a chronic disease, 3) Communication in daily work situations, 4) Facilities for disabled employees and work disability legislation, 5) How to stand up for oneself, 6) A plan to solve problems, 7) Follow-up.</p> <p>Methods</p> <p>Participants are recruited via occupational health services, patient organisations, employers, and a yearly national conference on chronic diseases. They are eligible when they have a chronic physical medical condition, have a paid job, and experience problems at work. Workers on long-term, 100% sick leave that is expected to continue during the training are excluded. After filling in the baseline questionnaire, the participants are randomised to either the control or the intervention group. The control group will receive no care or care as usual. Post-test mail questionnaires will be sent after 4, 8, 12 and 24 months. Primary outcome measures are job retention, self efficacy, fatigue and work pleasure. Secondary outcome measures are work-related problems, sick leave, quality of life, acquired work accommodations, burnout, and several quality of work measures. A process evaluation will be conducted and satisfaction with the training, its components and the training methods will be assessed.</p> <p>Discussion</p> <p>Many employees with a chronic condition experience problems in performing tasks and in managing social relations at work. We developed an innovative intervention that addresses practical as well as psychosocial problems. The results of the study will be relevant for employees, employers, occupational health professionals and human resource professionals (HRM).</p> <p>Trial registration</p> <p>ISRCTN77240155</p

Components Separation Technique Combined with a Double-Mesh Repair for Large Midline Incisional Hernia Repair

Background The surgical treatment of large midline incisional hernias remains a challenge. The aim of this report is to present the results of a new technique for large midline incisional hernia repair which combines the components- separation technique with a double-prostheticmesh repair. Methods The records of all consecutive patients who received a double-mesh combined with the componentsseparation technique for ventral hernia repair were reviewed. The clinical, surgical, and follow-up data were analyzed. Results Nine patients [3 women, 6 men; median age = 62 years (range = 26-77)] were included in the study. Median transverse defect size was 20 cm (range = 15-25). The median duration of hospital stay was 8 days (range = 5-17). Postoperative complications occurred in 66% (6/9). Follow-up [median = 13 months (range = 3-49)] showed no recurrent hernias, but one patient had a small hernia after a relaparotomy for colon carcinoma recurrence. The overall occurrence of wound infections was 44% (4/9). There was no mortality. Conclusion The components-separation technique in combination with a double-mesh has shown a low recurrence rate in the short-term follow-up. However, there is a considerable occurrence of postoperative wound infections. Long-term results of the hernia recurrence rate have to be awaited

Abnormal vaginal bleeding in women of reproductive age: a descriptive study of initial management in general practice

<p>Abstract</p> <p>Background</p> <p>Abnormal vaginal bleeding (AVB) in women of reproductive age is a common reason for consulting a general practitioner. Nevertheless, how general practitioners (GPs) choose to initially manage AVB is largely unknown, as is the prevalence of underlying pathology of AVB in primary care.</p> <p>Methods</p> <p>To investigate the initial diagnostic procedures and treatment for AVB used in general practice, we performed a descriptive study based on computerised medical records. New consultations for AVB in 2000 and 2001 were selected. Patient characteristics, diagnostic procedures and treatment were analysed.</p> <p>Results</p> <p>In total, 270 new consultations were included. The majority of patients (75%) consulted the GP for AVB only once. GPs performed diagnostic procedures in 54% of all consultations. Overall, additional diagnostic procedures revealed abnormalities in 11% of women. However, the diagnostic procedures implemented by the GPs varied widely per bleeding type and contraceptive use. Anaemia was found in 36% of 45 women tested. Uterine fibroids were found in 41% of 27 women examined by ultrasound. Medication was prescribed in 34% of all consultations. A gynaecological referral was registered in 4% of all contacts.</p> <p>Conclusion</p> <p>Initially, GPs tend to follow a policy of expectant management in women of reproductive age with AVB. However, when additional diagnostic procedures were performed, anaemia and uterine fibroids were found in a considerable number of women.</p

Preclinical PET imaging of bispecific antibody ERY974 targeting CD3 and glypican 3 reveals that tumor uptake correlates to T cell infiltrate

BACKGROUND: Bispecific antibodies redirecting T cells to the tumor obtain increasing interest as potential cancer immunotherapy. ERY974, a full-length bispecific antibody targeting CD3ε on T cells and glypican 3 (GPC3) on tumors, has been in clinical development However, information on the influence of T cells on biodistribution of bispecific antibodies, like ERY974, is scarce. Here, we report the biodistribution and tumor targeting of zirconium-89 (89Zr) labeled ERY974 in mouse models using immuno-positron emission tomography (PET) imaging. METHODS: To study both the role of GPC3 and CD3 on the biodistribution of [89Zr]Zr-N-suc-Df-ERY974, 89Zr-labeled control antibodies targeting CD3 and non-mammalian protein keyhole limpet hemocyanin (KLH) or KLH only were used. GPC3 dependent tumor targeting of [89Zr]Zr-N-suc-Df-ERY974 was tested in xenograft models with different levels of GPC3 expression. In addition, CD3 influence on biodistribution of [89Zr]Zr-N-suc-Df-ERY974 was evaluated by comparing biodistribution between tumor-bearing immunodeficient mice and mice reconstituted with human immune cells using microPET imaging and ex vivo biodistribution. Ex vivo autoradiography was used to study deep tissue distribution. RESULTS: In tumor-bearing immunodeficient mice, [89Zr]Zr-N-suc-Df-ERY974 tumor uptake was GPC3 dependent and specific over [89Zr]Zr-N-suc-Df-KLH/CD3 and [89Zr]Zr-N-suc-Df-KLH/KLH. In mice engrafted with human immune cells, [89Zr]Zr-N-suc-Df-ERY974 specific tumor uptake was higher than in immunodeficient mice. Ex vivo autoradiography demonstrated a preferential distribution of [89Zr]Zr-N-suc-Df-ERY974 to T cell rich tumor tissue. Next to tumor, highest specific [89Zr]Zr-N-suc-Df-ERY974 uptake was observed in spleen and lymph nodes. CONCLUSION: [89Zr]Zr-N-suc-Df-ERY974 can potentially be used to study ERY974 biodistribution in patients to support drug development

Bias in protein and potassium intake collected with 24-h recalls (EPIC-Soft) is rather comparable across European populations

Purpose: We investigated whether group-level bias of a 24-h recall estimate of protein and potassium intake, as compared to biomarkers, varied across European centers and whether this was influenced by characteristics of individuals or centers. Methods: The combined data from EFCOVAL and EPIC studies included 14 centers from 9 countries (n = 1,841). Dietary data were collected using a computerized 24-h recall (EPIC-Soft). Nitrogen and potassium in 24-h urine collections were used as reference method. Multilevel linear regression analysis was performed, including individual-level (e.g., BMI) and center-level (e.g., food pattern index) variables. Results: For protein intake, no between-center variation in bias was observed in men while it was 5.7% in women. For potassium intake, the between-center variation in bias was 8.9% in men and null in women. BMI was an important factor influencing the biases across centers (p <0.01 in all analyses). In addition, mode of administration (p = 0.06 in women) and day of the week (p = 0.03 in men and p = 0.06 in women) may have influenced the bias in protein intake across centers. After inclusion of these individual variables, between-center variation in bias in protein intake disappeared for women, whereas for potassium, it increased slightly in men (to 9.5%). Center-level variables did not influence the results. Conclusion: The results suggest that group-level bias in protein and potassium (for women) collected with 24-h recalls does not vary across centers and to a certain extent varies for potassium in men. BMI and study design aspects, rather than center-level characteristics, affected the biases across center

Ruthenacycles and Iridacycles as Catalysts for Asymmetric Transfer Hydrogenation and Racemisation

Ruthenacycles, which are easily prepared in a single step by reaction between enantiopure aromatic amines and [Ru(arene)Cl2]2 in the presence of NaOH and KPF6, are very good asymmetric transfer hydrogenation catalysts. A range of aromatic ketones were reduced using isopropanol in good yields with ee’s up to 98%. Iridacycles, which are prepared in similar fashion from [IrCp*Cl2]2 are excellent catalysts for the racemisation of secondary alcohols and chlorohydrins at room temperature. This allowed the development of a new dynamic kinetic resolution of chlorohydrins to the enantiopure epoxides in up to 90% yield and 98% enantiomeric excess (ee) using a mutant of the enzyme Haloalcohol dehalogenase C and an iridacycle as racemisation catalyst.

Outcome in hip fracture patients related to anemia at admission and allogeneic blood transfusion: an analysis of 1262 surgically treated patients

Background: Anemia is more often seen in older patients. As the mean age of hip fracture patients is rising, anemia is common in this population. Allogeneic blood transfusion (ABT) and anemia have been pointed out as possible risk factors for poorer outcome in hip fracture patients. Methods. In the timeframe 2005-2010, 1262 admissions for surgical treatment of a hip fracture in patients aged 65 years and older were recorded. Registration was prospective from 2008 on. Anemic and non-anemic patients (based on hemoglobin level at admission) were compared regarding clinical characteristics, mortality, delirium incidence, LOS, discharge to a nursing home and the 90-day readmission rate. Receiving an ABT, age, gender, ASA classification, type of fracture and anesthesia were used as possible confounders in multivariable regression analysis. Results: The prevalence of anemia and the rate of ABT both were 42.5%. Anemic patients were more likely to be older and men and had more often a trochanteric fracture, a higher ASA score and received more often an ABT. In univariate analysis, the 3- and 12-month mortality rate, delirium incidence and discharge to a nursing home rate were significantly worse in preoperatively anemic patients. In multivariable regression analysis, anemia at admission was a significant risk factor for discharge to a nursing home and readmission < 90 days, but not for mortality. Indication for ABT, age and ASA classification were independent risk factors for mortality at all moments, only the mortality rate for the 3-12 month interval was not influenced by ABT. An indication for an ABT was the largest negative contributor to a longer LOS (OR 2.26, 95% CI 1.73-2.94) and the second largest for delirium (OR 1.67, 95% CI 1.28-2.20). Conclusions: This study has demonstrated that anemia at admission and postoperative anemia needing an ABT (PANT) were independent risk factors for worse outcome in hip fracture patients. In multivariable regression analysis, anemia as such had no effect on mortality, due to a rescue effect of PANT. In-hospital, 3- and 12-month mortality was negatively affected by PANT, with the main effect in the first 3 months postoperatively

Synchronisation of egg hatching of brown hairstreak (Thecla betulae) and budburst of blackthorn (Prunus spinosa) in a warmer future

Synchronisation of the phenology of insect herbivores and their larval food plant is essential for the herbivores’ fitness. The monophagous brown hairstreak (Thecla betulae) lays its eggs during summer, hibernates as an egg, and hatches in April or May in the Netherlands. Its main larval food plant blackthorn (Prunus spinosa) flowers in early spring, just before the leaves appear. As soon as the Blackthorn opens its buds, and this varies with spring temperatures, food becomes available for the brown hairstreak. However, the suitability of the leaves as food for the young caterpillars is expected to decrease rapidly. Therefore, the timing of egg hatch is an important factor for larval growth. This study evaluates food availability for brown hairstreak at different temperatures. Egg hatch and budburst were monitored from 2004 to 2008 at different sites in the Netherlands. Results showed ample food availability at all monitored temperatures and sites but the degree of synchrony varied strongly with spring temperatures. To further study the effect of temperature on synchronisation, an experiment using normal temperatures of a reference year (T) and temperatures of T + 5°C was carried out in climate chambers. At T + 5°C, both budburst and egg hatch took place about 20 days earlier and thus, on average, elevated temperature did not affect synchrony. However, the total period of budburst was 11 days longer, whereas the period of egg hatching was 3 days shorter. The implications for larval growth by the brown hairstreak under a warmer climate are considered.

The programming of sequences of saccades

Saccadic eye movements move the high-resolution fovea to point at regions of interest. Saccades can only be generated serially (i.e., one at a time). However, what remains unclear is the extent to which saccades are programmed in parallel (i.e., a series of such moments can be planned together) and how far ahead such planning occurs. In the current experiment, we investigate this issue with a saccade contingent preview paradigm. Participants were asked to execute saccadic eye movements in response to seven small circles presented on a screen. The extent to which participants were given prior information about target locations was varied on a trial-by-trial basis: participants were aware of the location of the next target only, the next three, five, or all seven targets. The addition of new targets to the display was made during the saccade to the next target in the sequence. The overall time taken to complete the sequence was decreased as more targets were available up to all seven targets. This was a result of a reduction in the number of saccades being executed and a reduction in their saccade latencies. Surprisingly, these results suggest that, when faced with a demand to saccade to a large number of target locations, saccade preparation about all target locations is carried out in paralle
