There is ample evidence that children who are born preterm are at risk for language impairment [1-3]. However, not all children who are born preterm will experience difficulty developing language. Why some children have a language impairment and others do not may be owed to the presence of certain risk factors, as well as the absence of particular protective factors. It is possible that differe...

1,418 multiple sclerosis cases, 1,238 of whom were born in Northern Ireland, were analysed. A detailed study was made of the 783 cases born in Northern Ireland from 1901 to 1925. These cases were studied in relation to all live births that occurred in the administrative areas of the province during the period. The results showed a constant *case-rate over the years studied, and a remarkable def...

BACKGROUND Recent studies have demonstrated marked international variations in the prevalence of asthma, but less is known about ethnic variations in asthma epidemiology within individual countries and in particular the impact of migration on risk of developing asthma. Recent within country comparisons have however revealed that despite originating from areas of the world with a low risk for de...

BACKGROUND Better understanding about gastric cancer incidence patterns among Hispanics by birthplace, socioeconomic status (SES), and acculturation can improve preventive strategies and disease models. METHODS Incidence rates, rate ratios, and estimated annual percent change (EAPC) in rates of anatomic and histologic subtype-specific gastric cancer were calculated by age, sex, and nativity a...

OBJECTIVE To study the relation between diabetes incidence and sleep problems in a population-based sample of women followed for 32 years. RESEARCH DESIGN AND METHODS The researchers conducted a prospective population study initiated in 1968-1969, with follow-ups in 1974-1975, 1980-1981, 1992-1993, and 2000-2001 in Gothenburg, Sweden. A total of 1,462 women born in 1908, 1914, 1918, 1922, and...

The Ewald-Oseen extinction theorem states, that, inside a linear medium, the incident electromagnetic wave is extinguished by its interference with a part of the irradiation from the excited surface of the medium. This contradicts Huygens’ principle, according to which the incident wave is absent after having excited the sources of the secondary wavelets. In this contribution, the proof in Born...

This article presents new research on income-based child indicators for immigrant children from 17 different national backgrounds and children of parents born in Sweden observed during the 3-year periods 1983-85, 1995-97 and 2008-10. This research examines mean household income, representation at the top of the income distribution and relative poverty differ for immigrant children from the corr...
