PURPOSE: Up to 38% of prostate cancer survivors experience significant psychological distress; 6-16% are diagnosed with depression or anxiety disorders. Support from a relationship partner can ameliorate psychological distress, but many studies treat relationship status as a dichotomous predictor without accounting for level of support provided by the partner. METHODS: The current study is a secondary analysis of a sample of 292 prostate cancer survivors recruited by nine Community Clinical Oncology Program (CCOP) sites around the USA to a larger randomized controlled trial...

The 2 major and clinically most important primary inflammatory rheumatic diseases which affect small hand and feet joints are rheumatoid arthritis (RA) and psoriatic arthritis (PsA). The most important initial histopathological feature of RA is synovitis followed by chronic proliferative granulomatous pannus-tissue, which is associated with cartilage and bone destruction. Early inflammatory changes in RA also develop synchronously within the subchondral bone marrow. Enthesitis is the hallmark of SNSA, and is often seen as one of the first radiological manifestations of the diseases...

Different partial phylogenetic trees can be derived from different sources of evidence and different methods. One important problem is to summarize these partial phylogenetic trees using a supernetwork. We propose a novel simulated annealing based method called SNSA which uses an optimization function to produce a simple network that still retains a great deal of phylogenetic information. We report the performance of this new method on real and simulated datasets.

We reviewed ten patients with seronegative spondylarthropathy (SNSA), who all fulfilled the European Spondylarthropathy Study Group criteria for spondylarthropathy (SpA); seven patients also met the Amor criteria for SpA. Seronegative spondylarthropathy was not a uniform syndrome but rather a wide spectrum of complex disease with characteristics of sacroiliitis and enthesopathy. The most frequent symptom at diagnosis of SNSA was inflammatory low back pain, followed by asymmetric oligoarthralgia and Achilles tendonitis and/or plantar fasciitis...

BACKGROUND: We hypothesized that sympathetic nervous system activity (SNSA) is increased and parasympathetic nervous system activity (PNSA) is decreased during non-rapid eye movement (NREM) sleep in non-apneic, otherwise healthy, snoring individuals compared to control. Moreover, we hypothesized that these alterations in snoring individuals would be more evident during non-snoring than snoring when compared to control. METHODS: To test these hypotheses, heart rate variability was used to measure PNSA and SNSA in 11 normotensive non-apneic snorers and 12 control subjects before and 7-days after adapting to nasal continuous positive airway pressure (nCPAP)...

The immune system was studied in 90 patients with seronegative spondylarthritis (SNSA). Of them, 60 patients had ankylosing spondylarthritis (30 patients with central and 30 patients with peripheral forms) and 30 patients with reactive arthritis. SNSA patients were found to have secondary immunodeficiency. Cellular immunity was characterized by a decreased count of T mu (helper cells), an increased count of T gamma (cytotoxic/suppressors) and suppressed functional activity of lymphocytes, humoral immunity--by a high concentration of circulating immune complexes in an increased concentration of serum immunoglobulins...

Seronegative spondyloarthropathies (SNSA) include a group of diseases with arthritis that are negative for rheumatoid factor. The borders of the disease are sometimes obscure, and SNSA has its own classification criteria. The investigation on the speciality of HLA-B27 will be important for the understanding of SNSA pathogenesis. Several reports shows that anti-TNF-alpha therapy is powerful measure for the management of SNSA.

OBJECTIVE: Uveitis is a severe manifestation of rheumatic diseases since it can lead to visual impairment and even blindness. Ocular involvement is frequently a clinical challenge because its occurrence often requires changes of the therapeutic strategy. There are growing evidence that tumor necrosis factor alpha (TNFalpha) inhibitors may be an effective treatment of refractory uveitis. Purpose of this study was to evaluate the efficacy and safety of TNFalpha blocking agents in patients with seronegative spondylo-arthropathies (SNSA) and Behcet disease (BD) associated relapsing uveitis...

Susceptibility genes for seronegative spondyloarthropathy (SNSA) other than HLA-B27 remain unclarified. Sex hormones are implicated in the pathogenesis of SNSA. Cytochrome P450c17a (CYP17) is a key regulator of androgen biosynthesis, and a single nucleotide polymorphism (SNP) in the 5'-untranslated region of the CYP17 gene (CYP17), -34C > T, is associated with variety of diseases. We have investigated the association between the CYP17 SNP and SNSA in Japanese males. Genomic DNA was extracted from 149 Japanese male SNSA patients and 380 controls...

Sympathetic nervous system activity (SNSA) is believed to participate in the genesis of ventricular tachyarrhythmias (VTA) but understanding has been impeded by the number and complexity of effects and the paucity of data from humans. New information from studies of genetic disorders, animal models, and spontaneous human arrhythmias indicates the importance of the temporal pattern of SNSA in arrhythmia development. The proarrhythmic effects of short-term elevations of SNSA are exemplified by genetic disorders and include enhancement of early and delayed afterdepolarizations and increased dispersion of repolarization...

OBJECTIVES: To compare and establish the relevance of the relative degree of sympathetic nervous system activity (SNSA) in groups of patients with congestive heart failure (CHF) and obstructive sleep apnea (OSA), and in a control group. BACKGROUND: Elevated SNSA is a characteristic feature of CHF, as well as of OSA and nonhypercapnic central sleep apnea (CSA). OSA and CSA commonly occur with CHF; however, the relative contribution of apnea-related hypoxemia and sleep fragmentation to the SNSA of patients with CHF is not known...

STUDY OBJECTIVES: To investigate the nature and extent of the alteration in autonomic function following heterotopic lung transplantation. DESIGN: Measures of cardiac parasympathetic nervous system activity (PNSA) and systemic sympathetic nervous system activity (SNSA) were compared in lung transplant patients and age-matched healthy subjects, both at rest and following autonomic perturbation. SETTING: Lung transplantation service of a university teaching hospital...

STUDY OBJECTIVES: We hypothesized that blood pressure (BP) is less during snoring as compared to periods of non-snoring in non-apneic individuals. Furthermore, we hypothesized that this reduction may be accompanied by a simultaneous decrease in sympathetic (SNSA) and parasympathetic (PNSA) nervous system activity and an increase in heart rate (HR). DESIGN: N/A. SETTING: N/A. PATIENTS OR PARTICIPANTS: N/A. MEASUREMENTS: The variables mentioned above in addition to breathing frequency were measured in 9 subjects during NREM sleep...

BACKGROUND: L-type dihydropyridine calcium channel blockers (CCBs) have been implicated in increased cardiovascular events in patients with hypertension, perhaps due to adverse effects on autonomic nervous system (ANS) function. Blockade of T-type calcium channels may limit ANS dysfunction by inhibition of T channel-mediated neuroendocrine effects. OBJECTIVE AND DESIGN: This double-blind, parallel group study compared the effect of nifedipine gastrointestinal transport system (GITS) (L-type CCB) versus mibefradil (T-type CCB) on ANS function in patients with mild-moderate essential hypertension...

Adrenergic responsiveness (AR) appears to be increased in subjects with diabetes, but measurement of arterial AR in normotensive people with type 2 diabetes mellitus has not been previously reported. We sought to determine whether, compared with control subjects, there is increased arterial AR in type 2 diabetes mellitus and its relationship to the level of systemic sympathetic nervous system activity (SNSa). We studied 15 type 2 diabetic subjects aged 57 +/- 3 years without hypertension or clinical signs of autonomic neuropathy and 13 age-matched control subjects aged 55 +/- 2 years...

OBJECTIVE: To determine if the peripheral articular manifestations of the seronegative spondylarthropathies (SNSA) respond differently than the axial manifestations to treatment with sulfasalazine (SSZ). METHODS: This is a reanalysis of a previously reported series of randomized, double-blind, placebo-controlled, multicenter trials comparing the effects of SSZ, 2,000 mg/day, and placebo on the axial and peripheral articular manifestations of ankylosing spondylitis (AS), psoriatic arthritis (PsA), and reactive arthritis (ReA; Reiter's syndrome)...

Human prothrombin was acetylated to produce a modified prothrombin that upon activation by platelet-bound prothrombinase generates a form of thrombin that does not activate platelets but retains its amidolytic activity on a chromogenic peptide substrate. If normal prothrombin is used in such an assay, the thrombin that is generated activates the platelets in a feedback manner, accelerating the rate of thrombin generation and thereby preventing accurate measurement of the initial platelet procoagulant activity...

To define a possible association between familial Mediterranean fever (FMF) and seronegative spondyloarthropathy (SNSA) and to study features of SNSA in FMF patients, we screened for the presence and manifestations of SNSA in 3,000 FMF patients attending the National Center for FMF in our institution. This population included 160 patients with chronic arthritis, most who suffered from SNSA. Patients were considered to suffer from SNSA if they had chronic arthritis, inflammatory back/neck pain, and sacroiliitis...

The goal of this work was to evaluate clinico-radiological correlation of enthesitis in SNSA patients, selected for presenting at least one radiological enthesopathy. Out of 50 patients with SNSA, 40 were selected for having had at least one radiological enthesitis. In a cross-sectional study, 32 males and 8 females, whose mean age was 40.4 years and mean disease duration 13 years, were evaluated. Nineteen patients had ankylosing spondylitis, 15 psoriatic arthritis and 6 Reiter's syndrome. Sites evaluated were pelvis and lower limbs...

Between 1976 and 1989, 160 cases of seronegative spondyloarthropathy (SNSA) were admitted to the Department of Medicine at Chulalongkorn Hospital. The prevalence of idiopathic ankylosing spondylitis (IdAS) was 52 cases (32.5%), Reiter's syndrome (RS) 68 cases (42.5%), psoriatic arthritis (PsA) 28 cases (17.5%), reactive arthritis eight cases (5.0%) and Behcet's disease four cases (2.5%). Clinical comparison of the patients with IdAS, RS and PsA showed a male predominance in IdAS (90.2%), RS (97.1%) and PsA (71...
