- Description: Blood pressure is a heritable trait influenced by several biological pathways and responsive to environmental stimuli. Over one billion people worldwide have hypertension (≥140mmg Hg systolic blood pressure ≥90mmg Hg diastolic blood pressure). Even small increments in blood pressure are associated with an increased risk of cardiovascular events. This genome-wide association study of systolic and diastolic blood pressure, which used a multi-stage design in 200,000 individuals of European descent, identified sixteen novel loci: six of these loci contain genes previously known or suspected to regulate blood pressure (GUCY1A3 GUCY1B3, NPR3 C5orf23, ADM, FURIN FES, GOSR2, GNAS EDN3); the other ten provide new clues to blood pressure physiology. A genetic risk score based on 29 genome-wide significant variants was associated with hypertension, left ventricular wall thickness, stroke and coronary artery disease, but not kidney disease or kidney function. We also observed associations with blood pressure in East Asian, South Asian and African ancestry individuals. Our findings provide new insights into the genetics and biology of blood pressure, and suggest potential novel therapeutic pathways for cardiovascular disease prevention. © 2011 Macmillan Publishers Limited.

- Description: AIMS: Obesity and kidney diseases are common complex disorders with an increasing clinical and economic impact on healthcare around the globe. Our objective was to examine if modifiable anthropometric obesity indices show putatively causal association with kidney health and disease and highlight biological mechanisms of potential relevance to the association between obesity and the kidney. METHODS AND RESULTS: We performed observational, one-sample, two-sample Mendelian randomization (MR) and multivariable MR studies in

- Description: Introduction: The experiences and information needs for reproductive health counseling in women with chronic kidney disease (CKD) are poorly defined, despite the known importance of pregnancy planning in this higher-risk cohort. Methods: Australian adult women with CKD and their partners or family members completed a consumer codesigned survey about experiences of and preferences for pregnancy-related counseling, support, and education. Data were analyzed descriptively and with qualitative content analysis of free-text responses. Results: Responses were received from 102 women (CKD, n = 60; dialysis, n = 11; transplant, n = 26; unsure, n = 5 ) and 17 partners/family members. Pregnancy-related discussions were initiated mostly by women themselves (60.0%) compared to nephrologists (26.7%), and only after conception in 14.7%. Women found pregnancy-related discussions satisfactory (68.0%) and useful (50.7%) but also stressful (66.7%), with only 54.7% feeling in control of decision-making. Information deficits and quality, preformed decisions, clinician-patient disconnect, and burden of decision-making contributed to usefulness and outcomes of pregnancy-related counseling. Women received insufficient information about contraception (not provided in 35.2% of cases), medication safety (40.9%), fetal complications (33.8%) and emotional and psychological impact of pregnancy (73.2%). Women preferred counseling from nephrologists (86.4%), face-to-face settings (79.6%), websites (72.7%), handouts (61.4%), and online support groups (46.6%). High-quality, multiformat information by content experts, peer support, and psychological support were also strongly desired. Conclusion: This study highlights that preconception counseling and information needs of women with CKD are currently not being met. Frameworks and tools to assist patients and clinicians, particularly nephrologists, to initiate and conduct sensitive, useful, and informed shared decision-making (SDM) about pregnancy are urgently needed. © 2023
