BackgroundThe aim of this study was to evaluate sleep quality and the related variables in patients with rheumatoid arthritis (RA).MethodsNinety-four patients diagnosed with RA and fifty two healthy controls were enrolled in the study. Disease activity was assessed through the Disease Activity Score (DAS) 28 scale. All patients were assessed using the Rheumatoid Arthritis Quality of Life and Health Assessment Questionnaire scales, together with the Beck Depression Inventory. Radiological damage was calculated with the modified Larsen method. The Pittsburgh Sleep Quality Index (PSQI) was used for the evaluation of the sleep disturbance.ResultsThe patients with RA had significantly higher scores in the subjective sleep quality, sleep latency, habitual sleep efficiency, sleep disturbance domains and the total PSQI score compared to the healthy control group. According to the results of Spearman’s analysis, there was a significantly correlation between the age, disease activity, CRP, pain, fatigue, depression, functional disability, quality of life, radiological damage, menopause status, duration of morning stiffness, ESR levels and the sleep disturbance. The logistic regression analysis indicated that depression and DAS 28 scores were predictors for poor sleep quality.ConclusionThe sleep quality is disturbed in patients with RA. The poor sleep quality is especially associated with the disease activity and depression.
OBJECTIVE. The goal of this study is to evaluate the changes in the elasticity of the renal parenchyma in diabetic nephropathy using acoustic radiation force impulse imaging. SUBJECTS AND METHODS. The study included 281 healthy volunteers and 114 patients with diabetic nephropathy. In healthy volunteers, the kidney elasticity was assessed quantitatively by measuring the shear-wave velocity using acoustic radiation force impulse imaging based on age, body mass index, and sex. The changes in the renal elasticity were compared between the different stages of diabetic nephropathy and the healthy control group. RESULTS. In healthy volunteers, there was a statistically significant correlation between the shear-wave velocity values and age and sex. The shear-wave velocity values for the kidneys were 2.87, 3.14, 2.95, 2.68, and 2.55 m/s in patients with stage 1, 2, 3, 4, and 5 diabetic nephropathy, respectively, compared with 2.35 m/s for healthy control subjects. Acoustic radiation force impulse imaging was able to distinguish between the different diabetic nephropathy stages (except for stage 5) in the kidneys. The threshold value for predicting diabetic nephropathy was 2.43 m/s (sensitivity, 84.1%; specificity, 67.3%; positive predictive value, 93.1%; negative predictive value 50.8%; accuracy, 72.1%; positive likelihood ratio, 2.5; and negative likelihood ratio, 0.23). CONCLUSION. Acoustic radiation force impulse imaging could be used for the evaluation of the renal elasticity changes that are due to secondary structural and functional changes in diabetic nephropathy.
Our findings suggest decreasing SWV of renal units with increasing grades of vesicoureteric reflux, increasing DMSA-assessed renal damage and decreasing DMSA-assessed differential function.
Swyer-James-Macleod syndrome (SJMS) is a rare constrictive bronchiolitis with air-flow obstruction and a decreased number and diameter of ipsilateral peripheral pulmonary vessels. This syndrome is characterized by unilateral hyperlucency on chest radiography. Computed tomography provides useful additional information. The diagnosis is usually made in childhood but sometimes occurs in adulthood. The disease often presents with dyspnea, decreased exercise tolerance, cough, hemoptysis, and recurrent pulmonary infections. SJMS may be confused with asthma or pulmonary embolism due to similar symptoms and may result in inappropriate therapy. This case series examined the clinical and imaging spectrum of four patients who were diagnosed with SJMS in adulthood.
Acoustic radiation force impulse elastography is a rapid, radiation-free, and noninvasive tool for diagnosis of acute pancreatitis at initial hospital admission, with a higher success rate for diagnosis of acute pancreatitis than the grayscale sonography and CT.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
