BACKGROUND Injury has been identified as a major health problem in China. Different quantitative measures based on the concept of years of potential life lost have been derived for assessing the burden of injury and other diseases. However, few studies have been conducted to compare the usefulness of these measures in terms of providing practical information. This study aims to examine the util...

We determined the nutritional status of children less than five years of age in an area in rural western Kenya with intense malaria transmission, a high prevalence of severe anemia and human immunodeficiency virus, and high infant and under-five mortality (176/1,000 and 259/1,000). No information is available on the prevalence of malnutrition in this area. Three cross-sectional surveys were con...

Background: Anxiety is the commonest problems before surgery. Preoperative anxiety not only causes pain and many suffering for children, but also has a negative impact on the recovery after surgery and probably later than that. Selecting a low risk and cost-effective way to control children's anxiety before surgery seems necessary. Aim: Influence of the puppet Kolah Ghermezi on preoperative anx...

This study aims to investigate the relationship between current smoking and lifetime amount smoked and the incidence of dysphonia using data from a national cross-sectional survey that represents the Korean population. Subjects were 3,600 non-institutionalised civilian adults over the age of 19 (1,501 males and 2,099 females) who completed the laryngeal examination of the 2008 Korea National He...

Silicon-based. light-emitting devices (LED's) should find numerous uses in optoelectronics. For example, the integration of silicon LED's with silicon microelectronics could lead to reliable and inexpensive optical displays and optical interconnects. Until recently, however, it had not been possible to obtain efficient room-temperature luminescence from silicon. The demonstration in 1990 that a...

BACKGROUND Cash-based transfer programmes are an emerging strategy in the prevention of wasting in children, especially targeted at vulnerable households during periods of food insecurity or during emergencies. However, the evidence surrounding the use of either cash or voucher transfer programmes in the humanitarian context and on nutritional outcomes is elusive. More evidence is needed not on...

OBJECTIVE To assess the geographic distribution and trends of AIDS deaths for the 1988-1997 period in Mexico. MATERIAL AND METHODS Crude and adjusted mortality rates were estimated for the 1988-1997 period. A trend test was performed using the simple linear regression method. Standardized mortality ratios (SMR) and years of potential life lost (YPLL) were calculated for each Mexican state. ...
