This study aimed to clarify the role of blood lead level (Pb-B) as one of the cardiovascular risk factors. To evaluate the cardiovascular risk the second derivative finger photoplethysmogram (SDPTG) was used. The subjects comprised of 420 male bus drivers in Thailand. The subjects' age ranged from 20 to 60 yr. Mean age (+/- standard deviation) were 41.6 (+/- 7.7) yr. Mean working years was 8.8 ...

Peak expiratory flow rates were measured in 124 normal elderly men (55-85 yr) using the Wright's peak flow meter. In the less than 60 yrs age group (n = 32; mean age 57.7 yr) the PEFR was 431 +/- 13 lpm, while for the group greater than 60 yr (mean age 69.0 +/- 6.0; n = 92), the PEFR value was 373 +/- 11 1pm. These values are similar to those reported in other Indian studies, suggesting that th...

Length-based analyses were conducted to assess the stock of the green tiger shrimp Penaeus semisulcatus. Monthly carapace length frequency data were collected from commercial catches at two main landing sites on the Yemeni Red Sea coast for eight months. Growth parameters, mortalities, exploitation rate and yield per recruit were estimated for this species in this area. The estimated growth par...

Objectives: To update the incidence of type 1 and type 2 diabetes in children aged <19 years from 1997 to 2007 in Hong Kong. Methods: Retrospective population-based incidence study. Primary ascertainment: reviewing medical records of diabetes patients in all public hospitals. Secondary ascertainment: impractical upon implementation of personal data privacy ordinance in Hong Kong. Results: Type ...

The large sample of main sequence stars with Hipparcos parallaxes and estimates of the radial velocity has been used to study the relations among kinematics, age and heavy element content for the solar neighbourhood. The samples with V > -30 km s−1, although including stars as old as 1010 yr, have a very young component (age > ∼ 107 yr), and have a metallicity close to the solar one. Most of th...

BACKGROUND The relation between older age and nosocomial infection and mortality in the intensive care unit (ICU) is still a controversial issue. METHODS The authors prospectively studied 406 patients admitted to a surgical ICU, 106 of whom were more than 75 yr old. Information concerning ICU-acquired nosocomial infections, severity of illness, therapeutic activity, and hospital outcome was c...

BACKGROUND & OBJECTIVES Studies conducted to assess the prevalence of cardiovascular (CV) risk factors among different regions of the country show variation in risk factors in different age groups and urban and rural population. We undertook this study to determine the prevalence of cardiovascular risk factors among urban adults in a north Indian city. METHODS In a cross-sectional survey, 222...

There is still controversy about the auxological outcome of GnRH agonist treatment in patients with CPP and about the favorable age and auxological characteristics at start of treatment for achieving a normal final height (FH) or for preserving height potential. We analyzed the FH data of 52 young women from a prospective multicentric trial which was started in 1985. The aim of this analysis wa...

BACKGROUND Click-evoked auditory brainstem responses (ABRs) are a valuable tool for probing auditory system function and development. Although it has long been thought that the human auditory brainstem is fully mature by age 2 yr, recent evidence indicates a prolonged developmental trajectory. PURPOSE The purpose of this study was to determine the time course of ABR maturation in a preschool ...
