Validating the EQ-5D with time trade off for the German population

The aim of this survey study was to derive the societal values of the general public for the EuroQol EQ-5D. Using the same protocol as previously used in the United Kingdom, we compared the German values with the British. In face-to-face interviews a sample of 339 individuals in northern Germany valued 15 different health states from a sample of 36 states. Values were derived using the York MVH protocol for time trade-off (TTO) and a visual analogue scale (VAS). Values for all 243 health states of the EQ-5D were estimated by a regression model. The VAS values revealed close a resemblance to the British VAS results. German TTO values were higher than the British. This was especially the case for the worse health states. The results suggest that the TTO values are more related to national variables than values derived by VAS. The use of the TTO values of this investigation makes it possible to anticipate these cultural differences in studies carried out in Germany.     

Lymph node 8a as a prognostic marker for poorer prognosis in pancreatic and periampullary carcinoma

Objectives: An investigation of patients with pancreatic carcinoma aims to identify those who will benefit from surgery. Physical examination, radiology and laboratory findings are helpful. Most prognostic markers, such as lymph node status, micro metastasis and tumour differentiation, are not preoperatively accessible. Metastatic disease in lymph node 8a (Ln8a) in patients operated for pancreatic carcinoma has been reported to be a predictor of shorter overall survival (OS). This lymph node can be assessed preoperatively through resection (possibly even with laparoscopy) and subsequent histopathology. The value of the procedure is disputed. The aim of this study is to investigate whether metastatic disease in Ln8a is a predictor of decreased OS.

Materials and methods: In patients with suspected pancreatic or periampullary carcinoma, who were operated with pancreatoduodenectomy (PD), Ln8a was separately resected and analysed with standard and immuno-histochemical methods. Patients with or without metastasis in Ln8a were compared regarding OS.

Results: Between 2008 and 2011, 122 consecutive patients were eligible and 87 were resected and had LN8a analysed separately. Sixteen patients were Ln8a?+?and 71 were Ln8a-. Patients with Ln8a?+?had a significantly reduced median OS as compared to patients with Ln8a– (0.74 (95% CI 0.26–1.26) versus 5.91 years (95% CI 2.91–), p?Conclusion: Ln8a?+?was associated with a marked reduction of OS, indicating a possible role in the future preoperative workup in patients with a suspicion of pancreatic cancer.     

Antibacterial Activity of Pepducins,Allosterical Modulators of Formyl Peptide Receptor Signaling

Pepducins containing a fatty acid linked to an amino acid sequence derived from cytosolic parts of a G-protein-coupled receptor (GPCR) constitute a new group of lipopeptide tools in GPCR studies. Pepducins corresponding to the third intracellular loop of formyl peptide receptor 2 (FPR2) activate human neutrophils, and we show here that, in addition, these allosteric modulators of receptor activity also kill bacteria. The functional dualism of FPR2 pepducins could potentially be explored as a novel class of antibacterial drugs with immunomodulatory properties.     

Relationships of proactive behaviour with job-related affective well-being and anticipated retirement age: an exploration among older employees in Belgium

Developed countries throughout the world are challenged with the ageing of their labour force. In these societal contexts, low employment rates and early labour market exits of older employees are at stake, as well as arrangements for retirement, financial household considerations and mutual obligations between generations. Although proactive behaviour has been extensively studied, no research has addressed the proactive behaviour of older employees themselves when facing (re)hiring and retention versus early retirement. For the first time, this study tests the relationships of proactive behaviour with job-related affective well-being and anticipated retirement age in a sample of employees aged 50+ (N = 89) in Belgium. The findings are obtained by using a self-report questionnaire. Statistical analysis includes correlation and regression analysis. Major findings are that (i) proactive older employees feel energetic, enthusiastic, inspired, at ease, relaxed and satisfied; and (ii) later retirement is anticipated when experiencing positive affective well-being at study.     

Surgery for fulminating colitis during pregnancy

Two cases of fulminating colitis presenting during pregnancy are described. In both cases, resectional surgery was performed. In the first case, cesarean section was combined with subtotal colectomy and ileostomy during the 32nd week of gestation. In the second case, cesarean section was performed during the 33rd week of gestation and proctocolectomy in the puerperium. In both cases, histopathologic examination showed colitis more consistent with Crohn's disease. It is concluded that if fulminating colitis appears during pregnancy it should be treated in the same manner as in the nonpregnant state.     

Congenital CMV infection: prevalence in newborns and the impact on hearing deficit

Congenital cytomegalovirus (CMV) infection is asymptomatic in 90% of infected newborns but approximately 10-20% of these infants are at risk of developing sequelae later, mostly hearing deficit. The aims of the study were to investigate the prevalence of congenital CMV infection in a Swedish population of newborns and investigate the relative risk of hearing deficit in newborns with congenital CMV infection. The dried blood spot (DBS) samples of 6060 newborns in southern Stockholm during 12 months (October 2003-June 2004; August 2004-October 2004) were analysed for CMV DNA by TaqMan based real-time PCR. Hearing deficit was assessed by otoacoustic emission (OAE) within a newborn screening programme. 12 infants out of 6060 or 0.2% (95% CI 0.1-0.3%) had congenital CMV infection. One boy among the 12 infected infants had unilateral hearing loss, indicating that the risk of hearing loss is greatly increased (about 20 times) in CMV infected infants. No child developed ocular complications such as chorioretinopathy during 3 y of follow-up. Congenital CMV has an impact on child health but can easily be overlooked due to lack of signs in the neonatal period. Surveillance for congenital CMV is important in addition to programmes for prevention and treatment.     

A method for enzymatic dissociation of cells from isolated pancreatic islets

Summary An enzymatic method for isolation of single cells from the islets of Langerhans is described. The isolated cells appeared well preserved and survived for at least 7 days when maintained in culture. The dry mass of the isolated islet cells was found to be decreased 30 min after administration of alloxan to obese-hyperglycemic mice. Isolated individual islet cells from obese-hyperglycemic mice had a higher dry mass than those from their lean litter mates. Traduzione a cura di G. U.
