A prospective evaluation of the diagnostic value of video capsule endoscopy in patients initially classified as irritable bowel syndrome.
BACKGROUND: Irritable bowel syndrome (IBS) is characterized by chronic gastrointestinal dysfunction in the absence of detectable organic disease. The recently developed technique, video capsule endoscopy (CE), has been shown to be much more sensitive than traditional enterography in detecting mucosal changes in the small intestine. This study was performed to see if any earlier, not detectable by
Early development of retinal subtypes in long-term cultures of human embryonic retina.
Purpose: To study early signs of neuronal and glial differentiation in the human embryonic retina. Materials and Methods: 6.5-to 8-week-old human embryos were obtained from elective abortions. The neuroretinas were kept in culture as full-thickness sheets for 7-42 days. Results: The control retinas consisted of a neuroblast cell layer and a thin marginal zone. Most explants displayed presence of r
Neighborhood deprivation and inequities in coronary heart disease among patients with diabetes mellitus: A multilevel study of 334,000 patients.
We used multilevel models to investigate whether the odds of coronary heart disease (CHD) is higher in patients with diabetes mellitus (DM) living in deprived neighborhoods versus those living in wealthy neighborhoods. The Swedish nationwide prescription register was used to identify 334,000 patients aged 30 years and older with DM. The OR of CHD was significantly higher among patients with DM liv
Simulating Music with Associative Self-Organizing Maps
The value of debridement and Vacuum-Assisted Closure (V.A.C.) Therapy in diabetic foot ulcers.
BACKGROUND: Treatment of diabetic foot ulcers includes a number of different regimes such as glycaemic control, re-vascularization, surgical, local wound treatment, offloading and other non-surgical treatments. Although considered the standard of care, the scientific evidence behind the various debridements used is scarce. This presentation will focus on debridement and V.A.C. Therapy, two treatme
The first successful eccentric correction
This paper presents a new procedure for assessing off-axis refractive errors; in this case, oblique astigmatism. By using photorefraction to objectively measure the off-axis refraction, it is possible to identify and provide eccentric correction that results in better image quality for the preferred retinal location (PRL) or the trained retinal location (TRL). This paper describes the case of a 56
Upper-body morbidity after breast cancer: incidence and evidence for evaluation, prevention, and management within a prospective surveillance model of care.
The purpose of this paper is to review the incidence of upper-body morbidity (arm and breast symptoms, impairments, and lymphedema), methods for diagnosis, and prevention and treatment strategies. It was also the purpose to highlight the evidence base for integration of prospective surveillance for upper-body morbidity within standard clinical care of women with breast cancer. Between 10% and 64%
Clinicopathological concordance in dementia diagnostics.
OBJECTIVE: Accurate distinction between dementia subtypes is important for patient care and pharmacological treatment. Continuing systematic comparisons of clinical and neuropathological dementia diagnoses may provide a basis for further improvement of the diagnostic procedure. The purpose of this study was to investigate concordance between clinical dementia diagnosis and neuropathological findin
Blood transfusion after cardiac surgery: is it the patient or the transfusion that carries the risk?
Background: The transfusion of red blood cells (RBCs) after cardiac surgery has been associated with increased long-term mortality. This study reexamines this hypothesis by including pre-operative hemoglobin (Hb) levels and renal function in the analysis. Methods: A retrospective single-center study was performed including 5261 coronary artery bypass grafting (CABG) patients in a Cox proportional
Role of neutrophils in the activation of trypsinogen in severe acute pancreatitis.
The relationship between inflammation and proteolytic activation in pancreatitis is an unresolved issue in pancreatology. The purpose of this study was to define the influence of neutrophils on trypsinogen activation in severe AP. Pancreatitis was induced by infusion of taurocholate into the pancreatic duct in C57BL/6 mice. For neutrophil depletion, an anti-Gr-1 antibody was administered before pa
Elemental composition in vesicles of an arbuscular mycorrhizal fungus, as revealed by PIXE analysis.
We investigated element accumulation in vesicles of the arbuscular mycorrhizal (AM) fungus Glomus intraradices, extracted from the roots of inoculated leek plants. The elemental composition (elements heavier than Mg) was quantified using particle-induced X-ray emission (PIXE), in combination with scanning transmission ion microscopy (STIM). In vesicles, P was the most abundant of the elements anal
Prenatal compared with postnatal cleft diagnosis: What do the parents think?
Since the 1980s, prenatal detection of cleft lip with or without cleft palate (CLP) is possible with a transabdominal ultrasound. The improvement of prenatal detection has resulted in an increased demand for prenatal information and counselling. The aim of this study was to, by means of a questionnaire, evaluate how families, who received the diagnosis prenatally and postnatally, respectively, thi
Can resting-state functional MRI serve as a complement to task-based mapping of sensorimotor function? A test-retest reliability study in healthy volunteers.
PURPOSE: To investigate if resting-state functional MRI (fMRI) reliably can serve as a complement to task-based fMRI for presurgical mapping of the sensorimotor cortex. MATERIALS AND METHODS: Functional data were obtained in 10 healthy volunteers using a 3 Tesla MRI system. Each subject performed five bilateral finger tapping experiments interleaved with five resting-state experiments. Following p
Disturbed alpha-cell function in mice with beta-cell specific overexpression of human islet amyloid polypeptide.
Exogenous administration of islet amyloid polypeptide (IAPP) has been shown to inhibit both insulin and glucagon secretion. This study examined alpha-cell function in mice with beta-cell specific overexpression of human IAPP (hIAPP) after an oral protein gavage (75 mg whey protein/mouse). Baseline glucagon levels were higher in transgenic mice (41 +/- 4.0 pg/mL, n = 6) than in wildtype animals (19
Caring for undernourished patients in an orthopaedic setting.
This study elucidates the nursing of undernourished patients as experienced by eight registered clinical nurses and five nursing assistants by using content analysis. The participants' narratives describe the inner perspective of caring for undernourished patients, known in Sweden as ;the thin ones'. Categories identified were: frustration in nursing, joy in nursing and that undernourishment is ta
Cardiomyocyte cell cycle control and growth estimation in vivo- an analysis based on cardiomyocyte nuclei.
AIMS: Adult mammalian cardiomyocytes are traditionally viewed as being permanently withdrawn from the cell cycle. While some groups have reported none, others have reported extensive mitosis in adult myocardium under steady state conditions. Recently, a highly specific assay of (14)C dating in humans has suggested a continuous generation of cardiomyocytes in the adult, albeit at a very low rate. M
Hydrophobic ion pairing of a minocycline/Ca(2+)/AOT complex for preparation of drug-loaded PLGA nanoparticles with improved sustained release.
Polymeric nanoparticles is an established and efficient means to achieve controlled release of drugs. Incorporation of minocycline, an antibiotic with anti-inflammatory and neuroprotective properties, into biodegradable nanoparticles may therefore provide an efficient means to combat foreign body reactions to implanted electrodes in the brain. However, minocycline is commonly associated with poor
Gastrointestinal dysfunction contributes to weight loss in Huntington's disease mice.
Weight loss is the most important non-neurological complication of Huntington's disease (HD). It correlates with disease progression and affects the quality of life of HD patients, suggesting that it could be a valuable target for therapeutic intervention. The mechanism underlying weight loss in HD is unknown. Mutant huntingtin, the protein that causes the disease, is not only expressed in the bra
