Distribution of 'Candidatus Liberibacter asiaticus' Above and Below Ground in Texas Citrus.

Detection of 'Candidatus Liberibacter asiaticus' represents one of the most difficult, yet critical, steps of controlling Huanglongbing disease. Efficient detection relies on understanding the underlying distribution of bacteria within trees. To that end, we studied the distribution of 'Ca.

Ergocalciferol versus Cholecalciferol for Nutritional Vitamin D Replacement in CKD.

Background/aims: Is cholecalciferol (D3) superior to ergocalciferol (D2) in treating nutritional vitamin D deficiency in chronic kidney disease (CKD)? The answer to this question has not been fully explored.

Methods: A retrospective analysis of 57 patients with non-dialysis-requiring CKD was conducted to assess the relative effectiveness of D2 versus D3 replacement on circulating 25(OH)D levels. Levels of 25(OH) D were assessed at baseline, after attempted repletion with D2, and then after attempted repletion with D3.

Ethnic differences in 25-hydroxyvitamin D levels and response to treatment in CKD.

Aim: Nutritional vitamin D [25(OH)D] deficiency is common in patients with chronic kidney disease (CKD). No studies have specifically examined the differences between ethnic groups in response to ergocalciferol ("D2") therapy.

Methods: A retrospective analysis was performed to evaluate the effectiveness of D2 therapy as recommended by the KDOQI guidelines in 184 Hispanic and Caucasian nondialysis CKD patients.
