The Impact of Parental Diabetes on the Prevalence of Childhood Obesity

Background: Obesity among children and adolescents is a worldwide public health concern. Type 1 diabetes (T1D) and type 2 diabetes (T2D) incidence are increasing, with heredity and socioeconomic status as possible risk factors. How these factors affect the risk of childhood obesity remains unclear. The aim of this study was to investigate the association between obesity and parental diabetes among 12-year-olds in Sweden, and how it relates to parental education level.Methods: We used data collected within the Exploring the Iceberg of Celiacs in Sweden (ETICS) study, a cross-sectional multicenter national screening study for celiac disease in 12-year-old children. Relative risk (RR) and confidence interval (CI) were calculated for the association between parental diabetes and obesity, also stratifying for gender and highest parental education.Results: Among 11,050 children, for both children with parental T1D and T2D, 31% of the children were overweight or obese, compared with 21% among other children. Comparing those with parental T1D with those without parental T1D within gender, boys had a statistically significant higher risk [RR 1.6 (95% CI 1.3–2.0)], and girls had a nonsignificant increased risk [RR 1.3 (95% CI 0.95–1.8)], of being overweight. For children with parental T2D, both boys and girls had a statistically significant increased risk of 1.5. Parental education showed no sign of influencing the RRs.Conclusions: Parental diabetes is associated with an increased risk of overweight among children, independent of parental education. Concomitant parental diabetes and overweight should be particularly alarming criteria when prioritizing preventive interventions at an early age

Statin use and breast cancer survival - A Swedish nationwide study

Background: A sizeable body of evidence suggests that statins can cease breast cancer progression and prevent breast cancer recurrence. The latest studies have, however, not been supportive of such clinically beneficial effects. These discrepancies may be explained by insufficient power. This considerably sized study investigates the association between both pre- and post-diagnostic statin use and breast cancer outcome. Methods: A Swedish nation-wide retrospective cohort study of 20,559 Swedish women diagnosed with breast cancer (July 1st, 2005 through 2008). Dispensed statin medication was identified through the Swedish Prescription Registry. Breast cancer related death information was obtained from the national cause-of-death registry until December 31st, 2012. Cox regression models yielded hazard ratios (HR) and 95% confidence intervals (CI) regarding associations between statin use and breast cancer-specific and overall mortality. Results: During a median follow-up time of 61.6 months, a total of 4678 patients died, of which 2669 were considered breast cancer related deaths. Compared to non- or irregular use, regular pre-diagnostic statin use was associated with lower risk of breast cancer related deaths (HR = 0.77; 95% CI 0.63-0.95, P = 0.014). Similarly, post-diagnostic statin use compared to non-use was associated with lower risk of breast cancer related deaths (HR = 0.83; 95% CI 0.75-0.93, P = 0.001). Conclusion: This study supports the notion that statin use is protective regarding breast cancer related mortality in agreement with previous Scandinavian studies, although less so with studies in other populations. These disparities should be further investigated to pave the way for future randomized clinical trials investigating the role of statins in breast cancer

Retinal Imaging Findings in Inherited Retinal Diseases

Inherited retinal diseases (IRDs) represent one of the major causes of progressive and irreversible vision loss in the working-age population. Over the last few decades, advances in retinal imaging have allowed for an improvement in the phenotypic characterization of this group of diseases and have facilitated phenotype-to-genotype correlation studies. As a result, the number of clinical trials targeting IRDs has steadily increased, and commensurate to this, the need for novel reproducible outcome measures and endpoints has grown. This review aims to summarize and describe the clinical presentation, characteristic imaging findings, and imaging endpoint measures that are being used in clinical research on IRDs. For the purpose of this review, IRDs have been divided into four categories: (1) panretinal pigmentary retinopathies affecting rods or cones; (2) macular dystrophies; (3) stationary conditions; (4) hereditary vitreoretinopathies
