   Author : Ulf Tedgård; Enheten för pediatrisk hematologi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; reproduction; sense of coherence; risk factors; psychological reactions; genetic counselling; chorionic villus sampling; fetal blood sampling; fetoscopy; Haemophilia; prenatal diagnosis; therapeutic abortion; follow-up study; Pediatrics; Pediatri;

   Abstract : The general aim of this study has been to study the psychological, social and ethical aspects for carriers of haemophilia and their spouses, related to the development of techniques for carrier testing and for prenatal diagnosis (PD) of haemophilia. This was investigated by a semi-structured follow-up interview with 29 carriers of haemophilia with experience of PD by fetal blood sampling (FBS), and with 29 carriers (and 23 spouses) with experience of PD by chorionic villus sampling (CVS).

4. 7. Particulate phosphorus accumulation and net retention in constructed wetlands receiving agricultural runoff : Critical analysis of factors affecting retention estimates

   Author : Karin Johannesson; Karin Tonderski; Stefan Weisner; Uno Wennergren; Ben Surridge; Linköpings universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Phosphorus retention; constructed wetlands; agriculture; sampling strategy;

   Abstract : Övergödning är ett allvarligt miljöproblem, som bland annat orsakar omfattande blomningar av alger och blågrönbakterier. I söt- och brackvatten är fosfor ofta det mest begränsande näringsämnet för dessa organismer, varför en minskning av fosfortillförseln är nödvändig för att nå förbättringar. READ MORE

   Abstract : Background: Urinary tract infection (UTI) is a prevalent bacterial infection in children. The diagnosis is based on growth of bacteria in urine specimen and treatment is chosen out of knowledge of the present antimicrobial resistance situation. Vesicoureteral reflux (VUR) is a well-known risk factor for UTI in children. READ MORE
