Degree of Albuminuria is Associated With Increased Risk of Fragility Fractures Independent of Estimated GFR.

Introduction: Fragility fractures are common in persons with chronic kidney disease (CKD); however, the association between fragility fractures and albuminuria is not well-studied. The primary objective of this study is to determine the association of albuminuria with incident risk of fragility fractures. The secondary objective is to examine the risk of fragility fracture by estimated glomerular filtration rate (eGFR) and Kidney Disease Improving Global Outcomes (KDIGO) risk categories.

Factors affecting thyroid nodule fine needle aspiration non-diagnostic rates: a retrospective association study of 1975 thyroid biopsies.

Background: Thyroid nodules are common in clinical practice, and it is important to distinguish benign nodules, the vast majority, from malignant ones. Non-diagnostic (ND) samples have the potential to delay or mis-diagnose or lead to unnecessary surgeries, and it is important to examine what factors influence the ND rate. Prior literature has suggested that the impact of bedside cytology on ND rate is dependent on the initial adequacy rate, whereby higher ND rates benefit most from bedside cytology.

Parity and lactation are not associated with incident fragility fractures or radiographic vertebral fractures over 16 years of follow-up: Canadian Multicentre Osteoporosis Study (CaMos).

Unlabelled: Parity and lactation showed no associations with incident clinical fragility fractures or radiographic vertebral compression fractures in the 16-year CaMos prospective study. Parity was associated with slightly greater decline in femoral neck but not hip or spine areal bone mineral density (aBMD), while lactation showed no associations with aBMD change.

Purpose: Pregnancy and especially lactation cause loss of bone mass and microarchitectural changes, which temporarily increase fracture risk.

Spine bone mineral density increases after 6 months of exclusive lactation, even in women who keep breastfeeding.

Unlabelled: This pilot study enrolled 31 women who had breastfed exclusively for 6 months. Lumbar and thoracic BMD increased 4 and 5%, respectively. Femoral neck and total body BMD did not change.

Neither absence nor excess of FGF23 disturbs murine fetal-placental phosphorus homeostasis or prenatal skeletal development and mineralization.

Fibroblast growth factor-23 (FGF23) controls serum phosphorus largely through actions on the kidneys to excrete phosphorus and reduce calcitriol. Although these actions are well established in adults and children, the role that FGF23 plays in regulating fetal phosphorus metabolism has not been previously studied. We used several mouse models to study the effect of endogenous deficiency or excess of FGF23 on fetal phosphorus metabolism.

Access to genetic testing and genetic counseling in vulnerable populations: the d/Deaf and hard of hearing population.

Genetic testing holds great potential for preventing morbidities and mortalities for a number of diseases through early detection and effective intervention. As the number of genetic tests expand, so will public demand for these services. Therefore, it is essential to evaluate access to genetic testing and genetic services to ensure that all Canadians, including vulnerable groups, have equitable access to all forms of health care, in keeping with the mandate of the Canadian Health Act.
