Background/Aims: Patients with chronic kidney disease (CKD) have a high risk of gastrointestinal tract bleeding because of platelet dysfunction attributable to uremia, a poor blood supply, and frequent use of anticoagulant agents. We describe the colonoscopic characteristics of lower gastrointestinal tract bleeding (LGIB) in patients with CKD. Methods: A total of 230 hospitalized patients with CKD who underwent colonoscopy because of suspected LGIB between January 2003 and August 2016 were reviewed retrospectively. We categorized CKD into five stages according to the estimated glomerular filtration rate and compared the colonoscopic findings and clinical manifestations among these five subgroups. Results: Of the 230 patients with CKD suspected of LGIB, 73 (31.7%, 103 cases) were colonoscopically confirmed to exhibit LGIB. Their mean age was 65.7 ± 12.8 years, and 52.1% were female (n = 38). The most common causes of LGIB were hemorrhoidal bleeding (32 cases, 43.8%), followed by bleeding of colorectal ulcers (21 cases, 28.8%), diverticular bleeding (12 cases, 16.4%), colitis-related bleeding (12 cases, 16.4%), and angiodysplastic bleeding (12 cases, 16.4%). As the CKD stage progressed, the incidence of LGIB increased (p = 0.043). On multivariate logistic regression analysis, LGIB was more common in CKD patients with hemorrhoids (odds ratio [OR]: 4.349, 95% confidence interval [
The objective of this study was to investigate the effect of gait training using rhythmic auditory stimulation on gait symmetry of stroke patients. Forty chronic stroke patients were divided into four groups by intervention. Group A and B received auditory stimulation when they walk with comfortable gait speed. Group A received auditory stimulation to paralyzed side while group B to non-paralyzed side. Group C and D received auditory stimulation with 10% faster gait speed than their comfortable gait speed. Group C received auditory stimulation to paralyzed side while group D to non-paralyzed side. Gait training using auditory stimulation was done in each group during five minutes. Gait symmetry was evaluated by formula and temporal variables of gait were measured by gait analysis system. Step time was decreased significantly in all groups except group A (P<.05), and gait symmetry was also improved significantly in all groups except group A (P<.05). Cadence was increased significantly in all groups except group A (p<.05), but velocity was not increased in all groups. Therefore we conclude that RAS gait training is effective in improving gait symmetry and can be useful to stroke patient's gait training.
This study was carried out to investigate the protective effects and detoxification of oriental herb extracts mixture (Saururus chinensis, Taraxacum platycarpum, Ulmus macrocarpa, Glycyrrhiza glabra, Rhynchosia nulubilis) on TCDD-induced oxidative stress. Thirty five male rats were divided into 5 groups: normal control group received saline; vehicle control group received DMSO and acetone; only TCDD-treated group received multiple intraperitoneal injection of TCDD (100 μg/kg) and saline; post-treated group of OHEM (400 mg/kg/day) received oral administration for 5 weeks after TCDD treatment; and pre-treated group of OHEM (400 mg/kg/day) received oral administration for 6 weeks from 1 week before TCDD treatment. The elevated serum activities of alanine transaminase (AST), aspartate transaminase (ALT), alkaline phosphatase (ALP), lactate dehydrogenase (LDH) and atherorganic index due to TCDD were significantly decreased by the treatment of OHEM (p<0.05); the pre-treatment of OHEM was especially effective. Hydropic lesions and cytoplasmic vacuolizations in the liver of TCDD-treated rats were inhibited by the treatment of OHEM. Also, OHEM treatment reduced edemas in small intestine villus of TCDD-treated rats. These results suggest that OHEM from various oriental herb extracts might be a useful protective and detoxification agent against TCDD.
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.
