- AIM: To investigate how 1) maternal delivery mode and 2) prematurity in infants are associated to antibiotic treatment and length of hospital stay. METHODS: Women having given birth and infants 0-12 months discharged from hospital between July 2005 and November 2011 were identified from the Swedish National Patient Register. Medical records were reviewed for 203 women and 527 infants. The risk ratio (RR) between antibiotic treatment and 1) delivery mode in women; 2) prematurity in infants was calculated. Length of stay and days of antibiotic therapy were compared by Wilcoxon rank-sum test. RESULTS: Women: There was an association between emergency caesarean section (CS) and antibiotic treatment (RR 5.0 95% confidence interval (CI) 2.2-11.5), but not for elective CS. Length of stay was longer for CS (emergency and elective) compared to vaginal delivery (p<0.01). Infants: RR for antibiotic treatment in preterm compared to term infants was 1.4 (95% CI 1.0-1.9). Length of stay (p<0.01), but not days of therapy (p = 0.17), was higher in preterm compared to term infants. CONCLUSION: We found that emergency CS increased the probability of maternal antibiotic treatment during hospitalisation, but no difference was found between term and preterm infants. The results are well aligned with current guidelines and may be considered in future studies on the effects of antibiotics.

- Aim: Exposure to antibiotics in early life may affect future health. Most antibiotics are prescribed in outpatient care, but inpatient exposure is also important. We estimated how specific diagnoses in hospitals corresponded to individual antibiotic exposure. Methods: All pregnant women and children from birth to five-years-of-age with infectious diseases and common inpatient diagnoses between July 2005 and November 2011were identified from the Swedish National Patient Register. Random samples of individuals from pre-defined groups were drawn and medical records received from the clinics were manually reviewed for antibiotics. Results: Medical records for 4,319 hospital visits were requested and 3,797 (88%) were received. A quarter (25%) of children diagnosed as premature had received antibiotics and in children from one to five-years-of-age, diagnoses associated with bacterial infections were more commonly treated with antibiotics (62.4-90.6%) than those associated with viruses (6.3-22.2%). Pregnant women who had undergone a Caesarean section were more likely to be treated with antibiotics than those who had had a vaginal delivery (40.1% versus 11.1%). Conclusions: This study defines the proportion of new mothers and young children who received individual antibiotic treatment for specific inpatient diagnoses in Sweden and provides a useful basis for future studies focusing on antibiotic use.

- Introduction: Gastro-oesophageal reflux disease (GERD) is the most common non-allergic comorbidity in adults with asthma; however, comorbidity with other atopic diseases such as eczema and hay fever is unclear. The objective was to assess the comorbidity of GERD with asthma and atopic diseases and to investigate possible mechanisms, including genetic and/or affective factors.Methods: A co-twin control study harnessing 46 583 adult twins. Questionnaires on health status were linked to national patient and prescribed drug register data. Analyses tested associations of comorbidity between multiple definitions of atopic diseases (self-report and register-based) with GERD. Comparisons were made between unpaired, monozygotic (MZ) and dizygotic (DZ) twins to assess genetic liability. Affective traits (depression, anxiety and neuroticism) were added to models as possible explanatory factors.Results: The risk of GERD in those with asthma was OR (odds ratio) 1.52 (95% CI 1.38, 1.68), hay fever OR 1.22 (95%CI 1.12, 1.34) and eczema OR 1.23 (95%CI 1.10, 1.38). Adjusting for affective traits completely attenuated the comorbidity associations for hay fever and eczema with GERD, and partly for asthma with GERD. Co-twin control associations attenuated suggesting a shared cause for both GERD and atopic diseases. For example, all twins adjOR 1.32 (95%CI 1.00, 1.74), 0.97 (95% CI 0.76–1.23) and 1.11 (95%CI 0.85–1.45) for self-report asthma, hay fever and eczema with GERD respectively.Conclusions: GERD is a common comorbidity in adults with asthma, hay fever and/or eczema. We found evidence for shared mechanisms suggesting common underlying causes that may involve affective traits requiring further investigation.
