Olive oil-based lipid emulsion is noninferior to soybean oil-based lipid emulsion in the acute care setting: A double-blind randomized controlled trial.

Objectives: Olive oil (OO)-based intravenous lipid emulsion (IVLE) may have biological advantages for nutrition and inflammation status compared with soybean oil (SO)-based IVLE. We aimed to compare prealbumin levels during infusion of OO- or SO-based IVLE in patients receiving parenteral nutrition in the acute-care setting.

Methods: In this prospective, noninferiority, double blind randomized controlled efficacy trial, patients received either OO-based or SO-based IVLE after providing consent.

Assessment of parenteral nutrition prescription in Canadian acute care settings.

Background: Parenteral nutrition (PN) prescription can be challenging in patients with complex conditions and has potential complications.

Objective: To assess PN prescription, monitoring, and PN-related complications in a Canadian acute care setting.

Methods: This was a prospective cohort study in which patients receiving PN were assessed by an auditor for nutritional status, PN-related prescription, monitoring, and complications.

[Bone mineral density disminution post Roux-Y bypass surgery].

Introduction: Bariatric surgery has important metabolic complications such as bone mass loss.

Goal: To assess bone mineral density (BMD) after Roux-en-Y gastric by-pass (RYGB) in patients under standard calcium and vitamin D supplementation.

Method: In patients with morbid obesity submitted to RYGB, 76 women and 22 men of diverse age, all with standard nutritional instruction including vitamin D and calcium, we measured BMD with a dual X-ray densitometer.

[Evolution of the intake and nutritional status of zinc, iron and copper in women undergoing bariatric surgery until the second year after surgery].

Introduction: Bariatric surgery allows a significant reduction in weight and improvement of comorbidities associated with obesity in the long term, but it can also adversely affect the nutritional status of some micronutrients.

Objectives: To evaluate changes in intake and parameters of nutritional status of zinc, iron and copper in patients undergoing Roux-en-Y gastric bypass (GBP) or sleeve gastrectomy (SG), until the second postoperative year.

Methods: We prospectively studied 45 women undergoing GBP or SG (mean age 35.

[Alopecia in women with severe and morbid obesity who undergo bariatric surgery].

Introduction: Bariatric surgery leads to a significant body weigh reduction although it is associated to a higher risk of presenting some nutritional deficiencies. A common complication, little studied and mainly related to zinc deficiency is alopecia.

Objectives: To compare the nutritional status of zinc, iron, copper, selenium and protein-visceral in women with different degrees of hair loss at 6 months after gastric bypass or tubular gastrectomy.
