The current role of surgery in the treatment of gastroduodenal ulcer

Surgery for gastroduodenal ulcer disease has been declining in the past few decades and the role of surgery in the treatment of gastroduodenal ulcer has been referred to the treatment of this complications. In this paper, the authors proposed to study the current role of surgery in the treatment of this disease between January 2001 and December 2010. During this period 134 patients were operated, all for compli...

Hydrodynamic profile of young swimmers: changes over a competitive season

The aim of this study was to analyze the changes in the hydrodynamic profile of young swimmers over a competitive season and to compare the variations according to a well-designed training periodization. Twenty-five swimmers (13 boys and 12 girls) were evaluated in (a) October (M1); (b) March (M2); and (c) June (M3). Inertial and anthropometrical measures included body mass, swimmer’s added water mass, height, an...

The influence of ACE ID and ACTN3 R577X polymorphisms on lower-extremity functi...

Background We studied the influence of the ACE I/D and ACTN3 R577X polymorphisms (single or combined) on lower-extremity function in older women in response to high-speed power training. Methods One hundred and thirty-nine healthy older Caucasian women participated in this study (age: 65.5 ± 8.2 years, body mass: 67.0 ± 10.0 kg and height: 1.57 ± 0.06 m). Walking speed (S10) performance and functional capac...

Muscle tissue changes with aging

Sarcopenia is characterized by a progressive generalized decrease of skeletal muscle mass, strength and function with aging. Recent- ly, the genetic determination has been associated with muscle mass and muscle strength in elderly. These two phenotypes of risk are the most commonly recognized and studied for sarcopenia, with heritability ranging from 30 to 85% for muscle strength and 45-90% for muscle mass. I...

The influence of anthropometric, kinematic and energetic variables and gender o...

The aim of this study was to assess the: (i) gender; (ii) performance and; (iii) gender versus performance interactions in young swimmers’ anthropometric, kinematic and energetic variables. One hundred and thirty six young swimmers (62 boys: 12.76 ± 0.72 years old at Tanner stages 1-2 by self-evaluation; and 64 girls: 11.89 ± 0.93 years old at Tanner stages 1-2 by self-evaluation) were evaluated. Performance, a...

A significação do infarto agudo do miocárdio construída por doentes idosos

O envelhecimento da população europeia, em particular da portuguesa, é um facto simultaneamente indicativo do nível de desenvolvimento de uma sociedade e preocupante. Para este envelhecimento têm contribuído dois factores: a diminuição das taxas de natalidade e o aumento da esperança média de vida. Para a diminuição da taxa de natalidade têm contribuído muitas razões, de entre as quais destacamos um crescente a...

Effect of high-speed power training on improving muscular and functional perfor...

Introduction In older populations, maintenance of muscle power output is a key factor in everyday task performance, such as climbing stairs, rising from a chair and walking, as well as in decreasing the likelihood of falls, especially in women (Häkkinen et al., 1998; Izquierdo et al., 2001). The purpose of the study was to examine the effects of 12 weeks high-speed power training on maximal strength (1RM) and f...

TECNOLOGIAS ASSISTIVAS PARA PROFISSIONAIS DE SAÚDE: UM ESTUDO DE REPRESENTAÇÕES...

Objetivo: Conhecer as representações sociais sobre tecnologias assistivas construídas por profissionais de saúde que atendem em Unidades Básicas de Saúde e Centros de Atendimento aos Idosos. Método: Trata-se de um estudo exploratório realizado com 245 profissionais de ambos os sexos. Os dados foram obtidos através de uma entrevista semiestruturada e a análise foi realizada com o auxilio do software Alceste: 201...

The aim of this paper was to: (i) calibrate the Swimsportec® speedo-meter; (ii) concept and develop a software’s interface for it (iii) validate the full system. Calibration was done with an industrial robot. The robot arm’s performed a linear and horizontal path at a uniform movement for a set of wide range of velocities (0.5<v<4.5m/s) being the tension data acquire for each specific linear velocity. Software’...
