Country as the primary risk factor for renal amyloidosis in familial Mediterranean fever.

Abstract: Objective Familial Mediterranean fever (FMF), the prototype of autoinflammatory disorders, is caused by recessive mutations in the MEFV gene. Some FMF patients develop renal amyloidosis, a potentially fatal condition. This complication has mainly been associated with the M694V mutation, although the different study designs, small numbers of patients, and/or evaluation of few or no covariables calls this association into question. The aim of this study was to examine the controversial issue of amyloidosis susceptibility in FMF by determining the relative contributions of MEFV and numerous epidemiologic factors to the risk of renal amyloidosis. Methods Online questionnaires were completed at the MetaFMF database by patients at 35 centers in 14 countries. Using a standardized mode of data collection, we retrieved crude initial data from over half of the genetically confirmed FMF patients referred worldwide until May 2003 (2,482 cases, including 260 patients who developed renal amyloidosis). Results Amyloid nephropathy was present in 11.4% of the cases. In the total study population, country of recruitment was the leading risk factor for this manifestation (odds ratio 3.2 [95% confidence interval 1.8–5.9]), followed by M694V homozygosity, proband status, and disease duration. Differing results were found when countries were stratified. Conclusion Country of recruitment, rather than MEFV genotype, is the key risk factor for renal amyloidosis in FMF. This risk, which parallels infant mortality rates, indicates a possible environmental origin of amyloidosis susceptibility. The patient's country should be considered in addition to MEFV genotype as an indication for prophylactic colchicine, a treatment suggested for asymptomatic individuals who are incidentally discovered to be M694V homozygous.

A carbon footprint based reverse logistics network design model

Abstract: Due to the environmental legislation and regulations, manufacturing firms have realized the importance of adopting environmental friendly supply chain management (SCM) practices. In this paper, a mixed integer linear model is developed for a carbon footprint based reverse logistics network design. The proposed model aims at minimizing climate change (specifically, the CO2 footprint), and it employs reverse logistics activities to recover used products, hence combining the location/transportation decision problem. The proposed model is validated by examining a case study from the plastic sector.

West German Study Group Phase III PlanB Trial: First Prospective Outcome Data for the 21-Gene Recurrence Score Assay and Concordance of Prognostic Markers by Central and Local Pathology Assessment

Abstract: PurposeThe 21-gene Recurrence Score (RS) assay is a validated prognostic/predictive tool in early hormone receptor–positive breast cancer (BC); however, only a few prospective outcome results have been available so far. In the phase III PlanB trial, RS was prospectively used to define a subset of patients who received only endocrine therapy. We present 3-year outcome data and concordance analysis (among biomarkers/RS).Patients and MethodsCentral tumor bank was established prospectively from PlanB (intermediate and high-risk, locally human epidermal growth factor receptor 2–negative BC). After an early amendment, HR-positive, pN0-1 patients with RS ≤ 11 were recommended to omit chemotherapy.ResultsFrom 2009 to 2011, PlanB enrolled 3,198 patients with a median age of 56 years; 41.1% had node-positive and 32.5% grade 3 disease. In 348 patients (15.3%), chemotherapy was omitted based on RS ≤ 11. After 35 months median follow-up, 3-year disease-free survival in patients with RS ≤ 11 and endocrine therapy alone...

An increase in prevalence of diabetes mellitus in Jordan over 10 years

Abstract: Objective This study aimed to determine the prevalence of type 2 diabetes mellitus (DM) and impaired fasting glycemia (IFG), identify their associated factors, determine how the prevalence of type 2 DM has changed over 10 years, and assess the awareness and state of control of diabetes in Jordan. Methods Data were analyzed from a cross-sectional study that included a random sample of 1121 Jordanians aged 25 years and above. A subject was deemed affected by DM if this diagnosis was known to the patient or if his or her condition complies with the American Diabetes Association definition. IFG was defined as a fasting serum glucose level of ≥6.1 mmol/l (110 mg/dl) but 1c >7.5% was defined as "unsatisfactory" metabolic control. Results The age-standardized prevalence of diabetes and IFG was 17.1% and 7.8%, respectively, with no significant differences between women and men. Of the 195 diabetic subjects, 146 (74.9%) had been previously diagnosed. More than half (54%) of those previously diagnosed were found to be with unsatisfactory glycemic control. Compared to the 1994 survey, there was a significant increase in the prevalence of diabetes by 31.5%. Increase in age, increase in body mass index, and having a family history of diabetes were associated with increased odds of diabetes and IFG. While the level of education had no effect on IFG, higher level of education was associated with a decrease in the odds of having diabetes. Conlusion The prevalence of type 2 diabetes and IFG is high in Jordan and is increasing. More than half of the patients with diabetes have unsatisfactory control. Therefore, they are likely to benefit from programs aimed at encouraging behaviors toward achieving optimum weight as well as physical activity behaviors. Physicians caring for patients with diabetes may need to adopt a more vigorous approach for diabetes control.
