In today's world, technologic developments bring social and economic benefits to large sections of society; however, the health consequences these can be difficult predict manage. With rapid advances in electromagnetic field (EMF) technologies communications, children are increasingly exposed EMFs at earlier ages. Consistent epidemiologic evidence an association between childhood leukemia exposure extremely low frequency (ELF) magnetic fields has led their classification by International...

Previous pooled analyses have reported an association between magnetic fields and childhood leukaemia. We present a analysis based on primary data from studies residential leukaemia published after 2000. Seven with total of 10 865 cases 12 853 controls were included. The main focused 24-h field measurements or calculated in residences. In the combined results, risk increased increase exposure, but estimates imprecise. odds ratios for exposure categories 0.1–0.2 μT, 0.2–0.3 μT ⩾0.3 compared...

Background: The World Health Organization has emphasized the need for research into possible effects of radiofrequency fields in children. We examined association between prenatal and postnatal exposure to cell phones behavioral problems young Methods: Mothers were recruited Danish National Birth Cohort early pregnancy. When children those pregnancies reached 7 years age 2005 2006, mothers asked complete a questionnaire regarding current health status children, as well past phone use....

Summary Background and objectives There are conflicting research results about the survival differences between hemodialysis peritoneal dialysis, especially during first 2 years of dialysis treatment. Given challenges conducting randomized trials, differential rates modality switch transplantation, time-varying confounding in cohort data treatment, use novel analytical techniques observational cohorts can help examine versus discrepancy.

Incident hemodialysis patients have the highest mortality in first several months after starting dialysis treatments. We hypothesized that patterns and risk factors associated with this early differ from those later therapy periods.

Abstract The increasing deployment of mobile communication base stations led to an demand for epidemiological studies on possible health effects radio frequency emissions. methodological challenges such have been critically evaluated by a panel scientists in the fields radiofrequency engineering/dosimetry and epidemiology. Strengths weaknesses previous identified. Dosimetric concepts crucial aspects exposure assessment were terms different types outcomes. We conclude that principle station...

<h3>Background</h3> Potential health effects of cell phone use in children have not been adequately examined. As are using phones at earlier ages, research among this group has identified as the highest priority by both national and international organisations. The authors previously reported results from Danish National Birth Cohort (DNBC), which looked prenatal postnatal exposure to behavioural problems age 7 years. Exposure prenatally, a lesser degree postnatally, was associated with more...

Background: In the past 15 years, mobile telephone use has evolved from an uncommon activity to one with > 4.6 billion subscriptions worldwide. However, there is public concern about possibility that phones might cause cancer, especially brain tumors.Objectives: We reviewed evidence on whether phone raises risk of main types tumor—glioma and meningioma—with a particular focus recent publication largest epidemiologic study yet: 13-country Interphone Study.Discussion: Methodological deficits...

The association between exposure to extremely low-frequency electric and magnetic fields (ELF) childhood leukemia has led the classification of by International Agency for Research on Cancer as a "possible human carcinogen." This is regarded critical effect in risk assessment. Creating effective policy light widespread undisputed value safe, reliable, economic electricity society difficult requires estimates potential public health impact associated uncertainties.
