Restless legs syndrome/Willis–Ekbom disease prevalence in beta thalassemia patients

Purpose Both beta thalassemia and restless legs syndrome (RLS) patients share some common pathophysiological characteristics related to iron handling. In the present study, the aim was to explore the prevalence of RLS as well as to explore potential association between the syndrome and various quality of life-related parameters in a sample of beta thalassemia patients. Methods One hundred fourteen (age 40 ± 11 yr, 59 M/55F) beta thalassemia patients participated in this cross-sectional descriptive study. Patients were screened for RLS based on the international RLS study group diagnostic criteria as well as a battery of validated questionnaires. Results The prevalence of RLS in this sample of beta thalassemia patients was zero. The quality of life score was low (78 ± 18). Iron levels were within normal range (191 ± 66 mcg/dL) while ferritin levels were high as expected (1836 ± 225 ng/dL). Conclusions Our sample of patients comes from central Greece where the prevalence of RLS in the general population is 4% while in renal failure patients is 27%. To our surprise, there was no presence of RLS among this sample of beta thalassemia patients. The adequate levels of iron and ferritin often seen in these patients could be the reason of the absence of RLS symptoms

Restless legs syndrome is contributing to fatigue and low quality of life levels in hemodialysis patients

AIM: To examine whether hemodialysis (HD) patients with restless legs syndrome (RLS) are subjects of greater fatigue and impaired quality of life (QoL) compared to HD patients without RLS. METHODS: Eighty five stable HD patients participated in this study. According to their RLS status, the patients were divided into the RLS group (n = 23) and the non-RLS group (n = 62). QoL, fatigue, sleep quality, daily sleepiness and depression symptoms were assessed by using various questionnaires. Finally, biochemical parameters including iron, ferritin, hemoglobin, hematocrit and parathormone were assessed. RESULTS: The HD patients with RLS scored worse in all the questionnaires used in the study (P < 0.05). The patients with RLS were more likely to receive the HD therapy on the morning shift, whilst 43.5% of the RLS patients reported to experience the RLS symptoms also during HD. The severity of RLS was correlated with fatigue, depression score and sleep quality (P < 0.05). CONCLUSION: HD patients with RLS are subject to lower QoL related parameters and greater fatigue compared to HD patients without RLS. RLS should be successfully managed in order to improve the QoL of the sufferers

A Portal Technology to support European Organic Animal Production

Organic Agriculture (OA) is a reply to Global Society‘s interest in food safety and enviromental conservation. Many European countries have significantly developed the OA sector, where Organic Animal Farming (OAF) systems hold a major part. Since, OA principles, methods and products are constantly evolving, an increasing number of agricultural agencies are using Web sites or portals to provide OA information to stakeholders. However, finding trustworthy information on OA is still time consuming, fragmented and associated with linguistic obstacles. This paper reports a new on-line service that provides (a) access to multilingual, specialized, updated and certified on-line information covering all OA plant and animal production aspects, (b) access to electronic commerce and mobile services to all participants of the OA chain and (c) user-friendly access via various communication channels. The on-line services are implemented via a central portal at the European level, aiming to provide a single point access to vari-ous OA agents. The portal presented is the result of a research programme in the context of the European Union e-content project 11293 “BIO@GRO”. The http://bioagro.aua.gr portal is ambitious to cover all the information needs of the OA stakeholders

MEIS1 and BTBD9: genetic association with restless leg syndrome in end stage renal disease

Background: Restless legs syndrome (RLS) is a sleep related movement disorder that occurs both in an idiopathic form and in symptomatic varieties. RLS is a frequent and distressing comorbidity in end stage renal disease (ESRD). For idiopathic RLS (iRLS), genetic risk factors have been identified, but their role in RLS in ESRD has not been investigated yet. Therefore, a caseecontrol association study of these variants in ESRD patients was performed. Methods: The study genotyped 10 iRLS associated variants at four loci encompassing the genes MEIS1, BTBD9, MAP2K5/SKOR1, and PTPRD, in two independent caseecontrol samples from Germany and Greece using multiplex PCR and MALDI-TOF (matrix assisted laser desorption/ionisation time-of-flight) mass spectrometry. Statistical analysis was performed as logistic regression with age and gender as covariates. For the combined analysis a CochraneManteleHaenszel test was applied. Results: The study included 200 RLS-positive and 443 RLS-negative ESRD patients in the German sample, and 141 and 393 patients, respectively, in the Greek sample. In the German sample, variants in MEIS1 and BTBD9 were associated with RLS in ESRD (Pnom≤0.004, ORs 1.52 and 1.55), whereas, in the Greek sample, there was a trend for association to MAP2K5/SKOR1 and BTBD9 (Pnom≤0.08, ORs 1.41 and 1.33). In the combined analysis including all samples, BTBD9 was associated after correction for multiple testing (Pcorrected=0.0013, OR 1.47). Conclusions: This is the first demonstration of a genetic influence on RLS in ESRD patients with BTBD9 being significantly associated. The extent of the genetic predisposition could vary between different subgroups of RLS in ESRD
