PCA3 as a second-line biomarker in a prospective controlled randomized opportunistic prostate cancer screening programme
2017
Objectives: PCA3 performance as a single second line biomarker is compared to the European Randomised Study of Screening for Prostate Cancer risk calculator model 3 (ERSPC RC-3) in an opportunistic screening in prostate cancer (PCa). Material and methods: 5,199 men, aged 40-75y, underwent prostate-specific antigen (PSA) screening and digital rectal examination (DRE). Men with a normal DRE and PSA >= 3 ng/ml had a PCA3 test done. All men with PCA3 >= 35 underwent an initial biopsy (IBx) 12 cores. Men with PCA3 = 3 ng/ml and DRE is normal, IBx could be avoided in 12.5% less than if ERSPC RC-3 is used and would reduce the false negative cases by 36.2%. At a FU of 21.7 months, this dual protoco…
Acute performance evaluation of a new ventricular automatic capture algorithm
2006
Aims This study evaluated the acute clinical performance of a new ventricular automatic capture algorithm developed to work with all lead types and pacing vectors. Methods and results During regular pacemaker implant or replacement, AutoThreshold and manual threshold tests were performed in ventricular unipolar (UP) and bipolar (BP, if applicable) pacing using a customized external prototype INSIGNIA™ pacemaker. The success rate and accuracy of two different modes (commanded and ambulatory) of the automatic capture algorithm were used to evaluate the performance. Loss-of-capture events (two consecutive non-captured beats without backup pacing) were used to assess safety. Data of 53 patients…
Short-term effects of kinesio taping in the treatment of latent and active upper trapezius trigger points : two prospective, randomized, sham-control…
2019
Este es el artículo que se ha publicado de forma definitiva en: https://www.nature.com/articles/s41598-019-51146-4 The presence of myofascial trigger points (MTrPs) is one of the most common causes of musculoskeletal problems and may lead to limited professional activity. Among the various treatment methods proposed for MTrPs, Kinesio Taping (KT) is a non-invasive, painless, and less time-consuming method with fewer side efects that has become widely used as a therapeutic tool in a variety of prevention and rehabilitation protocols. The aim of the study was to evaluate the immediate and short-term efcacy of the space correction KT technique in patients with latent or active MTrPs in the upp…
Minimally invasive video-assisted thyroidectomy: four-year experience of a single team in a General Surgery Unit.
2013
Minimally invasive video-assisted thyroidectomy (MIVAT) is a surgical technique that has showed increasingly good results, particularly in endocrine surgery centers. The aim of this prospective, non-randomized study was to evaluate feasibility, advantages and critical aspects of MIVAT in a general surgery unit.Two hundred twenty-four patients underwent total thyroidectomy for benign thyroid disease from May, 2008 to April, 2011. They were divided into two groups: one underwent conventional thyroidectomy (CT), and the other underwent MIVAT. The inclusion criteria were thyroid volume ≤35 mL and main nodule size ≤35 mm. For each patient, socio-demographic variables, hospitalization data and ou…
Frequency, indications, outcomes, and predictive factors of opioid switching in an acute palliative care unit.
2007
The aim of this study was to prospectively evaluate the frequency, indications, outcomes, and predictive factors associated with opioid switching, using a protocol that had been clinically applied and viewed as effective for many years. A prospective study was carried out on a cohort of consecutive cancer patients who were receiving opioids but had an unacceptable balance between analgesia and adverse effects, despite symptomatic treatment of side effects. The initial conversion ratio between opioids and routes was as follows (mg/day): oral morphine 100=intravenous morphine 33=transdermal fentanyl 1=intravenous fentanyl 1=oral methadone 20=intravenous methadone 16=oral oxycodone 70=transder…
Diffusion weighted magnetic resonance imaging in the diagnosis of reversible ischaemic deficits of the brainstem
2002
Objectives: To evaluate the sensitivity of diffusion weighted magnetic resonance imaging (MRI) for the diagnosis of clinically suspected reversible ischaemic deficits of the brainstem. Methods: A total of 158 consecutive patients presenting with acute signs of brainstem dysfunction were investigated using EPI diffusion weighted MRI within 24 hours of the onset of symptoms. High resolution T1 and T2 weighted imaging was performed as a follow up after a median of six days Results: Fourteen of the 158 patients had a complete clinical recovery within 24 hours (transitory ischaemic attack (TIA)), and 19 patients recovered in less than one week (prolonged reversible neurological deficit (RIND)). …
Parental Physical Activity Associates With Offspring's Physical Activity Until Middle Age: A 30-Year Study.
2017
Background:Parents’ physical activity associates with their children’s physical activity. Prospective designs assessing this association are rare. This study examined how parents’ physical activity was associated with their children’s physical activity from childhood to middle adulthood in a 30-year prospective, population-based setting.Methods:Participants (n = 3596) were from the ongoing Cardiovascular Risk in Young Finns study started in 1980. Participants’ physical activity was self-reported at 8 phases from 1980 to 2011, and their parents’ physical activity at 1980. Analyses were adjusted for a set of health-related covariates assessed from 1980 to 2007.Results:High levels of mothers’ …
3T Double Inversion Recovery Magnetic Resonance Imaging: diagnostic advantages in the evaluation of cortical development anomalies
2016
Abstract Purpose The aim of this work was to investigate the diagnostic value of the DIR sequence at 3T MR imaging operating in the evaluation of cortical development anomalies. Methods We studied 40 patients, with a previous diagnosis of cortical dysplasia, by FLAIR-3D, DIR, FSE T2 and MPR-GE T1 sequences at 3T MRI. Two independent observers evaluated, for each sequence and lesion, some semiological aspects (cortical thickness, cortical signal intensity, white-gray matter blurring, subcortical white matter intensity). We made also a quantitative evaluation of the cortical signal intensity in lesion site, drawing a ROI on each MRI sequences and comparing them to the correspondent normal con…
Topodiagnostic implications of hemiataxia: An MRI-based brainstem mapping analysis
2007
The topodiagnostic implications of hemiataxia following lesions of the human brainstem are only incompletely understood. We performed a voxel-based statistical analysis of lesions documented on standardised MRI in 49 prospectively recruited patients with acute hemiataxia due to isolated unilateral brainstem infarction. For statistical analysis individual MRI lesions were normalised and imported in a three-dimensional voxel-based anatomical model of the human brainstem. Statistical analysis revealed hemiataxia to be associated with lesions of three distinct brainstem areas. The strongest correlation referred to ipsilateral rostral and dorsolateral medullary infarcts affecting the inferior ce…
ADC measurements in diffuse large B-cell lymphoma and follicular lymphoma: a DWI and cellularity study.
2012
Diffusion-weighted magnetic resonance imaging (DW-MRI) allows quantifying the random motion of water molecules in tissue by means of apparent diffusion coefficient (ADC) measurements. The aim of the study was to determine whether ADC measurements allow discrimination of diffuse large B-cell lymphoma (DLBCL) from follicular lymphoma (FL), and to examine the relationship between cellularity and ADC value of the tumor using DWI.Thirty-two patients with histologically proven non-Hodgkin lymphoma (21 with DLBCL and 11 with FL, 17 males and 15 females, mean age 62±13 years) underwent conventional MRI and DWI examination before treatment. The ADC values of DLBCL were compared to those of FL. The A…
