    Background:The heart failure (HF)-syndrome is associated with neuro-hormonal activation, chronic kidney disease (CKD), inflammation and alterations in the phosphorus-metabolism, all of which are involved in regulation of mineral bone density. However, the role of HF as an independent factor associated with metabolic bone disease (MBD) remains unclear. Methods:HF-patients undergoing dual X-ray absorptiometry (DEXA) were matched in a 1:2 fashion against age and gender matched controls without HF, to determine the proportion of osteoporosis (T-score <-2.5). HF-status was tested against known predictors of MBD. Correlation analysis and Z-score analysis were used to assess the impact of HF on age-related bone demineralisation. Results:A total of 190 HF-patients (age = 80 +/- 10 years, female = 61%) were age and gender matched to 380 controls. HF-patients had a higher proportion of osteoporosis (26 vs 17%;p = .007). HF patients had a lower averaged mineral bone density expressed in g/cm(2) (p = .030), T-scores (p = .001) and Z-scores (p <.001). After adjusting for the individual osteoporosis risk-factors of the FRAX-score, difference in baseline features, kidney function and phosphorus-metabolism alterations, heart failure remained independently associated with a lower averaged T-score (Adjusted beta= -0.189;p = .017). Heart failure was associated with an accelerated age-related decline in mineral bone density (p = .0418). Therapies with ACE-I or ARBs and beta-blockers associated with ameliorated bone demineralisation (p = .023, respectivelyp = .029), while loop diuretic associated with worsened bone demineralization (p <.001). Conclusion:Heart failure independently associates with MBD and higher prevalence of osteoporosis. Heart failure aggravates the aged related loss in mineral bone density while treatment with neuro-hormonal blockers seemed to ameliorate this finding

    The Impact of a Novel Computer-Based Decision Aid on Shared Decision-Making for Colorectal Cancer Screening: A Randomized Trial (Running head: SDM for CRC Screening)

    Eliciting patients’ preferences within a framework of shared decision-making (SDM) has been advocated as a strategy for increasing colorectal cancer (CRC) screening adherence. Our objective was to assess the effectiveness of a novel decision aid on SDM in the primary care setting

    Aid-Assisted Decision-Making and Colorectal Cancer Screening: A Randomized Controlled Trial

    Shared decision-making (SDM) is a widely recommended yet unproven strategy for increasing colorectal cancer (CRC) screening uptake. Previous trials of decision aids to increase SDM and CRC screening uptake have yielded mixed results

    The Relationship of Maternal Prepregnancy Body Mass Index and Pregnancy Weight Gain to Neurocognitive Function at Age 10 Years among Children Born Extremely Preterm

    OBJECTIVE: To assess the association between maternal prepregnancy body mass index and adequacy of pregnancy weight gain in relation to neurocognitive function in school-aged children born extremely preterm. STUDY DESIGN: Study participants were 535 ten-year-old children enrolled previously in the prospective multicenter Extremely Low Gestational Age Newborns cohort study who were products of singleton pregnancies. Soon after delivery, mothers provided information about prepregnancy weight. Prepregnancy body mass index and adequacy of weight gain were characterized based on this information. Children underwent a neurocognitive evaluation at 10 years of age. RESULTS: Maternal prepregnancy obesity was associated with increased odds of a lower score for Differential Ability Scales-II Verbal IQ, for Developmental Neuropsychological Assessment-II measures of processing speed and visual fine motor control, and for Wechsler Individual Achievement Test-III Spelling. Children born to mothers who gained an excessive amount of weight were at increased odds of a low score on the Oral and Written Language Scales Oral Expression assessment. Conversely, children whose mother did not gain an adequate amount of weight were at increased odds of a lower score on the Oral and Written Language Scales Oral Expression and Wechsler Individual Achievement Test-III Word Reading assessments. CONCLUSION: In this cohort of infants born extremely preterm, maternal obesity was associated with poorer performance on some assessments of neurocognitive function. Our findings are consistent with the observational and experimental literature and suggest that opportunities may exist to mitigate risk through education and behavioral intervention before pregnancy

Neuroimaging has informed our understanding of the neurobiology of anxiety disorders, but research has been limited by small sample sizes and low statistical power, as well as heterogenous imaging methodology. The ENIGMA-Anxiety Working Group has brought together researchers from around the world, in a harmonized and coordinated effort to address these challenges and generate more robust and reproducible findings. This paper elaborates on the concepts and methods informing the work of the working group to date, and describes the initial approach of the four subgroups studying generalized anxiety disorder, panic disorder, social anxiety disorder, and specific phobia. At present, the ENIGMA-Anxiety database contains information about more than 100 unique samples, from 16 countries and 59 institutes. Future directions include examining additional imaging modalities, integrating imaging and genetic data, and collaborating with other ENIGMA working groups. The ENIGMA consortium creates synergy at the intersection of global mental health and clinical neuroscience, and the ENIGMA-Anxiety Working Group extends the promise of this approach to neuroimaging research on anxiety disorders

    No prospective cohort study of high-risk children has used rigorous exposure assessment and optimal diagnostic procedures to examine the perinatal antecedents of autism spectrum disorder (ASD), separately among those with and without cognitive impairment

    Advanced Glycation End Products Impair Cardiac Atrial Appendage Stem Cells Properties

    Background: During myocardial infarction (MI), billions of cardiomyocytes are lost. The optimal therapy should effectively replace damaged cardiomyocytes, possibly with stem cells able to engraft and differentiate into adult functional cardiomyocytes. As such, cardiac atrial appendage stem cells (CASCs) are suitable candidates. However, the presence of elevated levels of advanced glycation end products (AGEs) in cardiac regions where CASCs are transplanted may affect their regenerative potential. In this study, we examine whether and how AGEs alter CASCs properties in vitro. Methods and Results: CASCs in culture were exposed to ranging AGEs concentrations (50 µg/mL to 400 µg/mL). CASCs survival, proliferation, and migration capacity were significantly decreased after 72 h of AGEs exposure. Apoptosis significantly increased with rising AGEs concentration. The harmful effects of these AGEs were partially blunted by pre-incubation with a receptor for AGEs (RAGE) inhibitor (25 µM FPS-ZM1), indicating the involvement of RAGE in the observed negative effects. Conclusion: AGEs have a time- and concentration-dependent negative effect on CASCs survival, proliferation, migration, and apoptosis in vitro, partially mediated through RAGE activation. Whether anti-AGEs therapies are an effective treatment in the setting of stem cell therapy after MI warrants further examination
