Cingulo-Insular Structural Alterations Associated with Psychogenic Symptoms, Childhood Abuse and PTSD in Functional Neurological Disorders
2017
Objective Adverse early-life events are predisposing factors for functional neurological disorder (FND) and post-traumatic stress disorder (PTSD). Cingulo-insular regions are implicated in the biology of both conditions and are sites of stress-mediated neuroplasticity. We hypothesised that functional neurological symptoms and the magnitude of childhood abuse would be associated with overlapping anterior cingulate cortex (ACC) and insular volumetric reductions, and that FND and PTSD symptoms would map onto distinct cingulo-insular areas. Methods This within-group voxel-based morphometry study probes volumetric associations with self-report measures of functional neurological symptoms, advers…
Robotic Versus Laparoscopic Gastric Resection for Primary Gastrointestinal Stromal Tumors5 cm: A Size-Matched and Location-Matched Comparison.
2017
This study compared robotic (RR) and laparoscopic resection (LR) for primary gastrointestinal stromal tumors (GISTs) of the stomach >5 cm. Twelve consecutive patients who underwent RR from 2012 to 2015 were matched for tumor size and location with 24 patients who underwent LR from 2000 to 2012. The median tumor size was 7.1 cm (range, 5.5 to 11.5). GISTs were resected by wedge resection (91.7%) or distal gastrectomy. The median RR operative time was longer than that of LR (162.5 vs. 130 min, respectively; P=0.004). Only 1 LR patient required conversion. The time to flatus and hospital stay were similar between groups. Overall, 3 patients developed minor postoperative complications that w…
Lifetime, 5-year and past-year prevalence of homelessness in Europe: a cross-national survey in eight European nations
2019
ObjectivesTo examine the lifetime, 5-year and past-year prevalence of homelessness among European citizens in eight European nations.DesignA nationally representative telephone survey using trained bilingual interviewers and computer-assisted telephone interview software.SettingThe study was conducted in France, Ireland, Italy, the Netherlands, Poland, Portugal, Spain and Sweden.ParticipantsEuropean adult citizens, selected from opt-in panels from March to December 2017. Total desired sample size was 5600, with 700 per country. Expected response rates of approximately 30% led to initial sample sizes of 2500 per country.Main outcome measuresHistory of homelessness was assessed for lifetime, …
Frequent blood flow restricted training not to failure and to failure induces similar gains in myonuclei and muscle mass
2021
The purpose of the present study was to compare the effects of short-term high-frequency failure vs non-failure blood flow–restricted resistance exercise (BFRRE) on changes in satellite cells (SCs), myonuclei, muscle size, and strength. Seventeen untrained men performed four sets of BFRRE to failure (Failure) with one leg and not to failure (Non-failure; 30-15-15-15 repetitions) with the other leg using knee-extensions at 20% of one repetition maximum (1RM). Fourteen sessions were distributed over two 5-day blocks, separated by a 10-day rest period. Muscle samples obtained before, at mid-training, and 10-day post-intervention (Post10) were analyzed for muscle fiber area (MFA), myonuclei, an…
Conservative surgery of renal cell carcinoma.
1986
Abstract From 1967 to 1985 conservative surgery (enucleation, n = 49; partial resection, n = 7) was performed for renal tumors in 57 patients (age 31-77, mean 54.8 years). Imperative indications for conservative surgery (n = 29) were chronic renal failure, benign pathology of contralateral kidney, functional or anatomical solitary kidney, and bilateral tumors. Elective conservative surgery (n = 28) was done for small, peripherally located lesions, in cases of uncertain malignancy and in one tumor detected by chance during stone surgery. Tumors removed for imperative indications were 2-11 cm (mean 5.8 cm) in size. In the elective group, tumor size ranged from 1 to 7 cm (mean 3.3 cm). Follow-…
Visual quality differences between orthokeratology and LASIK to compensate low-moderate myopia.
2013
PURPOSE: To assess the differences in visual performance between orthokeratology (ortho-k) and laser in situ keratomileusis (LASIK) for the treatment of low-to-moderate myopia. METHODS: An adaptive optics visual simulator (Imagine Eyes) was used to simulate the wavefront aberration patterns induced by ortho-k and LASIK for low and moderate myopia on 10 healthy eyes. Visual acuity (VA) at 100%, 50%, and 10% contrast levels and contrast sensitivity (CS) at 10, 20 and 25 cycles per degree (cpd) were then measured for 3- and 6-mm pupil sizes. RESULTS: Differences in VA for 3-mm pupil diameter were not found between ortho-k and LASIK. For 6-mm pupil size, LASIK provided significantly better VA v…
Increased cross-education of muscle strength and reduced corticospinal inhibition following eccentric strength training.
2015
Aim: Strength training of one limb results in a substantial increase in the strength of the untrained limb, however, it remains unknown what the corticospinal responses are following either eccentric or concentric strength training and how this relates to the cross-education of strength. The aim of this study was to determine if eccentric or concentric unilateral strength training differentially modulates corticospinal excitability, inhibition and the cross-transfer of strength. Methods: Changes in contralateral (left limb) concentric strength, eccentric strength, motor-evoked potentials, short-interval intracortical inhibition and silent period durations were analyzed in groups of young ad…
Territorial belonging of the middle hepatic vein in living liver donor candidates evaluated by three-dimensional computed tomographic reconstruction …
2009
Abstract Background Postoperative venous congestion can lead to graft and remnant liver failure in living donor liver transplantation. This study was designed to delineate ‘territorial belonging’ of the middle hepatic vein (MHV) and to identify hepatic venous anatomy at high risk of outflow congestion. Methods MHV belonging patterns for right (RHL) and left (LHL) hemilivers were evaluated by three-dimensional computed tomographic reconstruction and virtual hepatectomy in 138 consecutive living liver donor candidates. Results The right hepatic vein (RHV) was dominant in 84·1 per cent and an accessory inferior hepatic vein (IHV) was present in 47·1 per cent of livers. Three MHV belonging type…
Liver "Compliance": A previously unrecognized preoperative predictor of small-for-size syndrome in adult living donor liver transplantation
2008
The purpose of this study was to investigate the effect of liver compliance on computed tomography (CT) volumetry and to determine its association with postoperative small-for-size syndrome (SFSS).Unenhanced, arterial, and venous phase CT images of 83 consecutive living liver donors who underwent graft hepatectomy for adult-to-adult living donor liver transplantation (ALDLT) were prospectively subjected to three-dimensional (3-D) CT liver volume calculations and virtual 3-D liver partitioning. Graft volume estimates based on 3-D volumetry, which subtracted intrahepatic vascular volume from the "smallest" (native) unenhanced and the "largest" (venous) CT phases, were subsequently compared wi…
Corpus callosum area in patients with bipolar disorder with and without psychotic features: an international multicentre study
2015
Background Previous studies have reported MRI abnormalities of the corpus callosum (CC) in patients with bipolar disorder (BD), although only a few studies have directly compared callosal areas in psychotic versus nonpsychotic patients with this disorder. We sought to compare regional callosal areas in a large international multicentre sample of patients with BD and healthy controls. Methods We analyzed anatomic T-1 MRI data of patients with BD-I and healthy controls recruited from 4 sites (France, Germany, Ireland and the United States). We obtained the mid-sagittal areas of 7 CC subregions using an automatic CC delineation. Differences in regional callosal areas between patients and contr…
