OBJECTIVE To determine bone mass using quantitative phalangeal bone ultrasound in institutionalized schizophrenic patients under chronic treatment with antipsychotic drugs. METHODS A total of 73 patients with schizophrenia (25 women, mean age 59.84 +/- 17.01 years; 48 men, mean age 61.89 +/- 12.95 years) and 73 healthy subjects (25 women, mean age 60.37(More)
OBJECTIVE Nutritional factors, especially the two essential nutrients calcium and vitamin D, have been shown to play an important role in bone health. We wanted to determine the possible protective effect of calcium intake in adequate amounts on bone mass as assessed by quantitative ultrasound in postmenopausal women who also have a high intake of selenium.(More)
The moderate consumption of fish is recommended for a healthy diet and is also a feature of the Mediterranean diet. Fish is a major food group in diets throughout the world, and studies show that fish consumption is associated with a lower risk of a number of conditions. Spain has one of the highest annual per capita consumptions of fish worldwide. As fish(More)
While podobarometric techniques have been applied to the study of pressures in Hallux Valgus (HV), little is known about its clinical and radiological determinants. So, the aim of the present study was to determine the plantar pressure pattern in participants with mild HV, comparing to a control group, and their clinical and anthropometric determinants.(More)
BACKGROUND Stroke is a major public health problem. OBJECTIVE To use the Barthel Index to evaluate basic activities of daily living in stroke survivors and detect any predictors of functional outcome at 6 months after stroke. METHODS In an observational longitudinal study, data were gathered on consecutive patients admitted to the comprehensive stroke(More)
OBJECTIVE To study the effect of beer consumption on bone mass in a group of healthy women, by using phalangeal bone ultrasound to evaluate the amplitude-dependent speed of sound. METHODS This was a cross-sectional study of 1697 healthy women (mean age 48.4 y, body mass index (BMI) 19.0-32.0 kg/m(2)), recruited in a clinical convenience sample and(More)
Hallux valgus (HV) is a common, complex, and progressive deformity of the first ray, leading to biomechanical changes. The purpose of this study is to describe the midterm outcomes of the percutaneous distal soft tissue release-Akin procedure for mild hallux valgus on plantar pressures distribution, clinical outcome, and radiographic parameters. Twenty-six(More)
The purpose of this study was to: (a) determine the relationship between quantitative ultrasound (QUS) results and anthropometric, dietary and body composition factors and establish reference ranges for amplitude-dependent speed of sound (Ad-SoS) in the phalanges and broadband ultrasound attenuation (BUA) in the calcaneus of children from Extremadura,(More)
The Foot Posture Index (FPI) quantifies foot posture through the evaluation of six individual criteria. The objective of the present study was then to establish the plantar pressure differences between types of feet, and to study the capacity of the whole FPI value and the six individual criteria to predict the pattern of plantar pressures. In a sample of(More)
We aim to evaluate whether calcium and vitamin D intake is associated with 25-hydroxyvitamin D (25-OH-Vitamin D3) and parathyroid hormone (PTH) serum concentrations or is associated with either the phalangeal dual energy X-ray absorptiometry (pDXA) or the quantitative bone ultrasound (QUS) in independent elderly men. Serum PTH and 25-OH-Vitamin D3 were(More)
