Self-Reported versus Measured Height, Weight and Body Mass Index in Spanish Mediterranean Teenagers: Effects of Gender, Age and Weight on Perceptual …

2002

<i>Background:</i> To have a good physical appearance is a determining factor by which adolescents show a tendency to worry excessively about their weight. The aim of this work is to study the possible relationship between actual and perceived body weight, how it is considered and what strategies are followed for weight control among adolescents residing in Valencia. <i>Methods:</i> A sample of 568 students, 325 girls and 243 boys, aged 14–20 years, were selected from public high schools in Valencia. Their height and weight were used to calculate their actual body mass index (BMIO). The subjective perception of their physical measurements (BMIS) was evaluated by mean…

A rare clinical entity: stump appendicitis. Case report and complete review of literature.

2019

BACKGROUND: Stump appendicitis is a rare delayed complication post-appendectomy and it represents a diagnostic problem as clinicians are often not very familiar with this pathology. MATERIALS AND METHODS: One case of stump appendicitis has been reported in a 54 year old woman, whose acute phase was conservatively treated in our Department. A review of Medline literature was also carried out, from 1945 to 2015, showing 111 cases of stump appendicitis. RESULTS: Stump appendicitis has been reported after either open or laparoscopic appendectomy, in a range between days to several years from the first procedure. Nowadays, it is not considered yet as a possible differential diagnosis in patients…

Comparison of training and anthropometric characteristics between recreational male half-marathoners and marathoners

2013

Zillmann, Teresa | Knechtle, Beat | Ruest, Christoph Alexander | Knechtle, Patrizia | Rosemann, Thomas | Lepers, Romuald; International audience; ''Participation in endurance running such as half-marathon (21-km) and marathon (42-km) has increased over the last decades. We compared 147 recreational male half-marathoners and 126 recreational male marathoners to investigate similarities or differences in their anthropometric and training characteristics. The half-marathoners were heavier (P < 0.05), had longer legs (P < 0.001), thicker upper arms (P < 0.05), a thicker thigh (P < 0.01), a higher sum of skinfold thicknesses (P < 0.01), a higher body fat percentage (P < 0.05) and a higher skelet…

The effect of vibration therapy on neck myofascial trigger points: A randomized controlled pilot study

2020

[EN] Background: The purpose of this study was to evaluate the effect of low-frequency self-administered vibration therapy into myofascial trigger points in the upper trapezius and levator scapulae on patients with chronic non-specific neck pain. Methods: Twenty-eight patients with chronic non-specific neck pain were randomly assigned into a vibration group, receiving 10 self-applied sessions of vibration therapy in the upper trapezius and levator scapulae trigger points; or a control group, receiving no intervention. Self-reported neck pain and disability (Neck Disability Index) and pressure pain threshold were assessed at baseline and after the first, fifth and 10th treatment sessions. Fi…

Keratinizing Desquamative Squamous Metaplasia of the Upper Urinary Tract: Leukoplakia—Cholesteatoma

Inverse regulation of vascular endothelial growth factor and VHL tumor suppressor gene in sporadic renal cell carcinomas is correlated with vascular …

1999

Tumors associated with the VHL (von Hippel-Lindau) disease, such as hemangioblastomas and renal carcinomas and their sporadic counterparts, are cystic and well vascularized. Mutations of the VHL tumor-suppressor gene and elevated levels of vascular endothelial growth factor (VEGF) have been described in these tumors. The upregulation of VEGF has been shown in vitro as a consequence of alteration of the VHL gene. No comprehensive in vivo analysis has yet been carried out of the factors affecting tumor growth, vascularization, VEGF, and VHL expression. We performed immunohistochemistry and mRNA studies on primary sporadic renal carcinomas and matching normal renal tissue. We semiquantitativel…

Pointing to double-step visual stimuli from a standing position: very short latency (express) corrections are observed in upper and lower limbs and m…

2010

How fast can we correct a planned movement following an unexpected target jump? Subjects, starting in an upright standing position, were required to point to a target that randomly and unexpectedly jumps forward to a constant spatial location. Rapid motor corrections in the upper and lower limbs, with latency responses of less than 100 ms, were revealed by contrasting electromyographic activities in perturbed and unperturbed trials. The earliest responses were observed primarily in the anterior section of the deltoidus anterior (shoulder) and the tibialis anterior (leg) muscles. Our findings indicate that visual on-going movement corrections may be accomplished via fast loops at the level o…

Relationship between velocity and muscular endurance of the upper body

2018

Strength, power and muscular endurance tests have been developed as means of assessing people's physical abilities. However, testing may be expensive or time consuming. A method to reduce the time of physical assessment could be to use predictive algorithms for indirect assessment. The aim of this study will be to determine a relationship between strength, power and muscular endurance in order to identify predictors for an easier and faster assessment. 33 male strength-trained participants (22.8 ± 4.6 years, 172.5 ± 6.7 cm, 68.0 ± 10.6 kg) performed a single pull-up (SPU) and a single push-up (SPH) and a set of pull-ups (EPU) and push-ups (EPH) to exhaustion. The participants were divided i…

Validity of Using Velocity to Estimate Intensity in Resistance Exercises in Men and Women

2020

AbstractThis study aimed to examine the validity of using bar velocity to estimate relative load in squat and bench-press exercises for both young men and women. Twenty-five men and 25 women performed a progressive loading test up to 1-RM in the squat and bench-press exercises, which were repeated after 2-weeks. Relationships between mean propulsive velocity and%1-RM were analysed. A second-order polynomial equation for predicting the corresponding velocity of each percentage of 1-RM was developed for men (validation). This equation was then applied in women (cross-validation). Moreover, a specific equation for women was developed (validation) and was also applied in a sub-sample of women (…

Accuracy of a no-biopsy approach for the diagnosis of coeliac disease across different adult cohorts

2020

ObjectiveWe aimed to determine the predictive capacity and diagnostic yield of a 10-fold increase in serum IgA antitissue transglutaminase (tTG) antibody levels for detecting small intestinal injury diagnostic of coeliac disease (CD) in adult patients.DesignThe study comprised three adult cohorts. Cohort 1: 740 patients assessed in the specialist CD clinic at a UK centre; cohort 2: 532 patients with low suspicion for CD referred for upper GI endoscopy at a UK centre; cohort 3: 145 patients with raised tTG titres from multiple international sites. Marsh 3 histology was used as a reference standard against which we determined the performance characteristics of an IgA tTG titre of ≥10×ULN for …
