BACKGROUND: There is evidence linking restless legs syndrome (RLS) with increased blood pressure (BP), but the mechanism of this relation remains unclear. Is the BP increased due to some features of RLS or to deterioration of sleep caused by RLS? This study compared values of nocturnal BP in patients with RLS and patients with insomnia. If increased BP in RLS is a consequence of disordered sleep, then it should be similar to increased BP in insomnia. METHODS: Polysomnographic recordings of patients admitted to a sleep center with RLS or insomnia were analyzed...

Dopaminergic drugs have been used as the first-line treatment for restless legs syndrome (RLS) for many years and are considered to be, at least over the short-term, effective and safe. However, the main long-term complication of dopaminergic treatment is augmentation, which is an overall increase in symptom severity and intensity, with symptoms starting earlier in the afternoon and expanding to previously unaffected parts of the body. Augmentation is a common complication, with prevalence rates of nearly 50%, and is a common cause of treatment failure...

Randomized search heuristics are frequently applied to NP-hard combinatorial optimization problems. The runtime analysis of randomized search heuristics has contributed tremendously to their theoretical understanding. Recently, randomized search heuristics have been examined regarding their achievable progress within a fixed time budget. We follow this approach and present a fixed budget analysis for an NP-hard combinatorial optimization problem. We consider the well-known Traveling Salesperson problem (TSP) and analyze the fitness increase that randomized search heuristics are able to achieve within a given fixed time budget...

OBJECTIVE: To make evidence-based recommendations regarding restless legs syndrome (RLS) management in adults. METHODS: Articles were classified per the 2004 American Academy of Neurology evidence rating scheme. Recommendations were tied to evidence strength. RESULTS AND RECOMMENDATIONS: In moderate to severe primary RLS, clinicians should consider prescribing medication to reduce RLS symptoms. Strong evidence supports pramipexole, rotigotine, cabergoline, and gabapentin enacarbil use (Level A); moderate evidence supports ropinirole, pregabalin, and IV ferric carboxymaltose use (Level B)...

STUDY OBJECTIVES: In this study, we investigated the prevalence of symptoms of restless legs syndrome (RLS) in biological caregivers of children with a diagnosis of autism spectrum disorder (ASD).The relationship of RLS symptoms to caregiver health-related quality of life (HRQoL) was also examined. Finally, we compared the sleep quality and daytime behaviors of children with ASD in caregivers with and without symptoms of RLS. METHODS: Biological caregivers (N = 50) of children ages 6 to 11 y with a diagnosis of ASD completed a Sleep Habits Questionnaire (SHQ) that included RLS as determined by four questions...

BACKGROUND: Retention on lifelong antiretroviral therapy (ART) is essential in sustaining treatment success while preventing HIV drug resistance (HIVDR), especially in resource-limited settings (RLS). In an era of rising numbers of patients on ART, mastering patients in care is becoming more strategic for programmatic interventions. Due to lapses and uncertainty with the current WHO sampling approach in Cameroon, we thus aimed to ascertain the national performance of, and determinants in, retention on ART at 12 months...

Α case of a chronic idiopathic form of a severe type of Restless Legs Syndrome (RLS), which developed during pregnancy and persisted after this, misdiagnosed for 34 years as radiculopathy S1, is reported. In spite of the thorough clinical and laboratory investigation, in addition to constant changes of the therapeutic approach, the diagnosis of S1 radiculopathy could not be confirmed, resulting in a chronic clinical course; the latter was characterized by relapses and remissions not attributed or linked in any way to the treatment (various types of)...

A recent meta-analysis suggests an association between the rs11558538 single nucleotide polymorphism in the histamine-N-methyl-transferase (HNMT) gene and the risk for Parkinson's disease. Based on the possible relationship between PD and restless legs syndrome (RLS), we tried to establish whether rs11558538 SNP is associated with the risk for RLS. We studied the genotype and allelic variant frequencies of HNMT rs11558538 SNP 205 RLS patients and 410 healthy controls using a TaqMan assay. The frequencies of the HNMT rs11558538 genotypes allelic variants were similar between RLS patients and controls, and were not influenced by gender, family history of RLS, or RLS severity...

Cellular aging in Saccharomyces cerevisiae can lead to genomic instability and impaired mitotic asymmetry. To investigate the role of oxidative stress in cellular aging, we examined the effect of exogenous hydrogen peroxide on genomic instability and mitotic asymmetry in a collection of yeast strains with diverse backgrounds. We treated yeast cells with hydrogen peroxide and monitored the changes of viability and the frequencies of loss of heterozygosity (LOH) in response to hydrogen peroxide doses. The mid-transition points of viability and LOH were quantified using sigmoid mathematical functions...

Transpulmonary ultrasound dilution (TPUD) method, a novel indicator dilution (ID) technique for cardiac output measurement, detects and quantifies shunts, both in children and adults. However, its accuracy and reproducibility in cardiac right-to-left-shunt (RLS) detection have not been investigated. In a prospective observational study, we assessed the validity of TPUD algorithm for RLS detection in children with congenital heart disease (CHD) and proven RLS in comparison with controls without shunts between February 2010 and October 2011...

OBJECTIVE: Previous studies have suggested that early-onset RLS (EOR) and late-onset RLS (LOR) might have different etiopathophysiologies. Few previous studies have examined accumulation of cerebrovascular ischemic changes as a potential cause of LOR. METHODS: We recruited 39 RLS subjects (LOR: defined as age of RLS onset ≥45, n = 18 and EOR: age of onset <45; n = 21); and 39 healthy control subjects matched on age and sex. Structural magnetic resonance imaging (MRI) of the brain was performed for each subject, and images were graded for severity of periventricular white matter hyperintensities (PVH) and deep white matter hyperintensities (DWMH) independently by trained raters according to standardized methods...

BACKGROUND: Restless legs syndrome (RLS) is defined as the spontaneous movement of the limbs (mainly legs) associated with unpleasant, sometimes painful sensation which is relieved by moving the affected limb. Prevalence of RLS among people on dialysis has been estimated between 6.6% and 80%. RLS symptoms contribute to impaired quality of life and people with RLS are shown to have increased cardiovascular morbidity and mortality.Various pharmacological and non-pharmacological interventions have been used to treat primary RLS...

Flavobacterium columnare is the causative agent of columnaris disease and causes tremendous morbidity and mortality of farmed fish globally. Previously, we identified a potential lectin-mediator (a rhamnose-binding lectin; RBL1a) of F. columnare adhesion and showed higher RBL1a expression in susceptible channel catfish under basal conditions and following infection. Exposure of challenged fish to the carbohydrate ligand l-rhamnose just prior to a challenge substantially decreased columnaris mortality and pathogen adherence via the down-regulation of RBL1a...

Relationships between the purity, pH, hydrophobicity (logKow) of the carbon substrate, and the critical micelle concentration (CMC) of rhamnolipid type biosurfactants (RL) were investigated using a quantitative structure-property relationship (QSPR) approach and are presented here for the first time. Measured and literature CMC values of 97 RLs, representing biosurfactants at different stages of purification, were considered. An arbitrary scale for RLs purity was proposed and used in the modelling. A modified evolutionary algorithm was used to create clusters of equations to optimally describe the relationship between CMC and logKow, pH and purity (the optimal equation had an R(2) of 0...

BACKGROUND: Due to the symptoms and the sleep disturbances it causes, Restless Legs Syndrome (RLS) has a negative impact on quality of life. Measurement of such impact can be performed by means of questionnaires, such as the Kohnen Restless Legs Syndrome-Quality of Life questionnaire (KRLS-QoL), a specific 12-item instrument that is self-applied by patients. The present study is aimed at performing a first formal validation study of this instrument. METHODS: Eight hundred ninety-one patients were included for analysis...
