in this article, we have focused one some basic and productive information about the properties of spectrum and singular values related to compact operators which are ideals in a c*-algebra of bounded operators. considering a two-sided connection between the family of symmetric gauge functions on sequence of singular values of compact operators and symmetric norms on finite dimensional ope...
Background & Aim: Although mechanical ventilation is a life-saving intervention for many infants with respiratory distress syndrome, it carries potential complications. One of these complications is prolonged duration of mechanical ventilation. More than 15 days of mechanical ventilation is associated with increased risk of cerebral palsy and attention deficit hyperactivity disorder among extre...

OBJECTIVE Seasonal environment at birth may influence diabetes incidence in later life. We sought evidence for this effect in a large sample of diabetic youth residing in the U.S. RESEARCH DESIGN AND METHODS We compared the distribution of birth months within the SEARCH for Diabetes in Youth Study (SEARCH study) with the monthly distributions in U.S. births tabulated by race for years 1982-20...
OBJECTIVE The association between low birth weight and type 2 diabetes is well established. We studied whether preterm birth carries a similar risk. RESEARCH DESIGN AND METHODS The Helsinki Birth Cohort includes 13,345 men and women born between 1934 and 1944. Of them, 12,813 had adequate data on length of gestation, which we linked with data on special reimbursement for diabetes medication. ...
Using data from 8,951 first-time mothers in the National Survey of Family Growth, the authors analyzed trends in union contexts during the transition to motherhood by social class (proxied by maternal education). Conventional classifications of union contexts as married or cohabiting were extended by classifying births relative to union status at conception. The most conventional married birth ...
BACKGROUND Micronutrient deficiencies may be related to poor fetal growth and short gestation. Few studies have investigated the contribution of maternal vitamin A deficiency to these outcomes. OBJECTIVE In rural northwestern Bangladesh, we examined the effects of weekly antenatal vitamin A and β-carotene supplementation on birth weight, length, circumferential body measures, and length of ge...
Background Preterm birth significantly affects the neonates’ survival. It also increases the risk of neonatal complications, prolongs the hospitalization period, and imposes high costs on the public health system. This study is aimed to assess the risk factors of the preterm birth. Materials and Methods This case-control stud...
