Treatment of Extreme Central Venous Occlusive Disease With Massive Esophageal Bleeding.

Central venous occlusions are common in the population of dialysis patients and develop as a result of arteriovenous access. Whereas these patients most commonly present with edema and varicosities, a rare presentation is esophageal varices. Here we present the case of a young man with life-threatening esophageal hemorrhage as a result of central venous occlusions, successfully treated with an azygos vein to right atrial bypass.

A novel approach for inferring effects on pregnancy loss.

Identifying the determinants of pregnancy loss is a critical public health concern. However, pregnancy loss is often not noticed, and even when it is, it is inconsistently recorded. Thus, past studies have been limited to medically-identified losses or small, highly selected cohorts, which can lead to biased or non-generalizable results.

A Five-Year Prospective, Randomized, Open-Label Study of Standard-Dose Versus Low-Dose Prolonged-Release Tacrolimus With or Without Angiotensin-Converting Enzyme Inhibitor or Angiotensin II Receptor Blocker Post Kidney Transplantation.

Introduction: Novel approaches to improve long-term outcomes in kidney transplant recipients are required. Here, we present the 5-year data from a multicenter, prospective, Phase 3b trial evaluating treatment outcomes with standard (STD) or low (LOW) dose prolonged-release tacrolimus (TAC) combined with ACEi/ARB or other antihypertensive therapy (OAHT) in Canadian kidney transplant recipients.

Methods: Adult de novo kidney transplant recipients were randomized 2 × 2 to STD or LOW dose TAC and ACEi/ARB or OAHT.

Fine particulate matter and nonaccidental and cause-specific mortality: Do associations vary by exposure assessment method?

Background: There is considerable heterogeneity in fine particulate matter (PM)-mortality associations between studies, potentially due to differences in exposure assessment methods. Our aim was to evaluate associations of PM predicted from different models with nonaccidental and cause-specific mortality.

Methods: We followed 107,906 participants of the Nurses' Health Study cohort from 2001 to 2016.
