Stiffness index of the calcaneus was obtained from quantitative ultrasound ...

BACKGROUND/AIMS: Ultrasonographic determination of gallbladder motility is sparsely performed in clinical practice as the examination is considered to be time consuming and there is uncertainty about a number of parameters possibly influencing the results. The aims of this study were a) to establish normal values for a simple ultrasonographic test ...

Women have a higher risk of developing torsade de pointes under OT-prolonging conditions. The electrophysiological differences between the sexes that could account for this are largely unknown. The objective of the work was to evaluate gender differences in repolarisation potentials using a method that is independent of the specific electrical ...

BACKGROUND: Indices of pressure wave reflection (RI(DVP)) and large artery stiffness (SI(DVP)) can be derived from the digital volume pulse (DVP). Indices obtained from the second derivative of the DVP have also been proposed to characterize vascular aging and effects of vasoactive drugs. METHODS: We compared RI(DVP) and SI(DVP) with ...

It is accepted that older subjects have increasing arterial stiffness resulting in changes in the propagation of the pulse to the periphery, and thereby influencing the peripheral pulse timing and shape characteristics. However, this age association with pulse shape is less clear in younger subjects and for different peripheral measurement ...

BACKGROUND: Several studies have reported an association between sleep disordered breathing (SDB) and hypertension (HT) but there is still a debate as to whether this is an effect of confounders. Some researchers have found an age dependent relationship between SDB and HT with higher risk at lower ages. A case-control ...

To investigate the major factors associated with the development of obstructive sleep apnea syndrome (OSAS) by logistic step regression analysis. Fifty-nine patients with OSAS and 57 normal adults were included in the study. The dependent was whether the subject had OSAS, and the independents included age, sex, body mass index ...

The atlas of Greulich and Pyle for skeletal maturity and epiphyseal closure is widely used in many countries to assess skeletal age and to plan orthopaedic surgery. The data used to compile the atlas were collected from institutionalised American children in the 1950s. In order to determine whether the atlas ...

This study was planned for the purpose of investigating the effect of hand preference on hand anthropometric measurements, with the participation of 393 healthy university students. The hand preference direction of the subjects was established according to the Edinburgh Inventory, and five hand preference determination groups were constituted after calculation ...

BACKGROUND: Sleep-disordered breathing (SDB) is common, but largely undiagnosed in the general population. Information on demographic patterns of SDB occurrence and its predictive factors in the general population is needed to target high-risk groups that may benefit from diagnosis. METHODS: The sample comprised 5615 community-dwelling men and women aged between ...

Significant mitral regurgitation (MR) may result from primary valve dysfunction or develop secondary to ischemic or dilated cardiomyopathy. The index 'isovolumic contraction time and isovolumic relaxation time divided by ejection time' (ICT + IRT/ET, 'Tei-index') is a well established measure of global cardiac function in patients with dilated cardiomyopathy and ...

PARTICIPANTS: Three thousand four hundred forty-eight subjects (1852 male, 1596 female) aged 7 ...

People age at remarkably different rates, but how to estimate trajectories of senescence is controversial. In a secondary analysis of a representative cohort of Canadians aged 65 and over (n = 2914) we estimated a frailty index based on the proportion of 20 deficits observed in a structured clinical examination. ...

Thirty-three runners were clinically diagnosed with plantar heel pain (PHP) and 107 runners were designated into a non-PHP group (NPHP). Cases were matched with a further control group of 64 subjects with regard to body mass index and age. A weight-bearing platform measured heel pad thickness by real-time ultrasound scanning. ...

METHODS: ABP measurement ...

Attempts were made to promote germination of naturally and artificially aged rice seeds by treating them with cerium nitrate. The germination rate, germination index, and vigor index of aged rice seed were significantly increased by cerium. It was because the treatments of aged rice seed with cerium nitrate enhanced respiratory ...

OBJECTIVE: To establish a statistical diagnostic method to identify patients with Minamata disease (MD) considering factors of aging and sex, we analyzed the neurological findings in MD patients, inhabitants in a methylmercury polluted (MP) area, and inhabitants in a non-MP area. MATERIALS AND METHODS: We compared the neurological findings in ...

To evaluate the indices used to compare the results of limb lengthening with distraction osteogenesis, we analyzed the relationship between the lengthening and external fixation period in a series of 28 patients (30 limbs). The average lengthening was 4.6 cm (range, 2.0-8.9). The average age at operation was 16.6 years ...

We performed this study to determine whether instituting monitoring of bispectral index (BIS) throughout an entire operating room would affect end-tidal gas concentration (as a surrogate for anesthetic use) or speed of recovery after outpatient surgery. Primary caregivers (n = 69) were randomly assigned to a BIS or non-BIS Control ...

Annual variation and relationship between the gonadosomatic index (IG) and the condition index (K) of Holacanthus passer were evaluated in 194 specimens from Cueva de León, Gulf of California (24 degrees 02' N, 110 degrees 24' W). There was a significant negative correlation between IG and K in both sexes: ...

This paper develops a method for appraising health status in elderly people. A frailty index was defined as the proportion of accumulated deficits (symptoms, signs, functional impairments, and laboratory abnormalities). It serves as an individual state variable, reflecting severity of illness and proximity to death. In a representative database of ...

Craniofacial and anthropometric characteristics are identified risk factors for obstructive sleep apnea syndrome (OSAS). Phase 1 of this study used cephalometric radiographs to record craniofacial measurements from 60 OSAS subjects with a respiratory disturbances index (RDI) of 20 or greater (group A) and 60 subjects with a history of loud ...

We wished to determine if obstructive sleep apnea (OSA) is associated with increased left ventricular mass (LVM) and impaired left ventricular diastolic function (LVDF) independently of coexisting obesity, hypertension (HTN), and diabetes mellitus (DM). Patients without primary cardiac disease, referred for evaluation of OSA (n = 533), had overnight polysomnography ...

More than thirty complete specimens of Carcineretes planetarius Vega, Feldmann, Ocampo, and Pope, 1997, a member of the extinct decapod family Carcineretidae, have been collected from the upper part of the Ocozocuautla Formation in Chiapas, southeast Mexico. Stratigraphic occurrences of Carcineretes in the Caribbean Province suggest that this crab should ...

We investigated diving beetle (Dytiscidae) assemblages in twelve wetlands in an agricultural landscape in southeastern Sweden. Beetles were trapped in wetlands that varied in permanence (temporary or permanent), area (25 to 4,800 m2), age (11 to >50 yr), and shading (open to wooded surroundings). Our objective was to determine if ...

Aging reduces cardiac baroreflex sensitivity. Our primary aim in the present study was to assess the effects of aging on cardiac baroreflex sensitivity, as determined by power spectral analysis (alpha index), in a large population of healthy subjects.

We carried out four experiments to assess the extent to which familiarity with certain objects in everyday life is related to gender and can account, at least partially, for the semantic category dissociation observed in a few brain-damaged patients. In the first experiment, 210 normal subjects, half males and half ...

OBJECTIVE: Obesity is an important etiologic factor in sleep-disordered breathing (SDB), but the extent to which changes in obesity across adult life contribute independently to SDB in old age has not been studied. In this study, we examined the association between changes in obesity from midlife to late adulthood and ...
