Long-term survival for COPD patients receiving noninvasive ventilation for acute respiratory failure

Implementation of noninvasive ventilation (NIV) as an add-on treatment has been routinely used in a non-intensive care setting since 2004 for patients with chronic obstructive pulmonary disease (COPD) and acute hypercapnic respiratory failure at a university hospital in Denmark. Although randomized controlled trials show lowered mortality rates in highly selected patients with acute exacerbation and respiratory failure, there are only few reports on long-term survival after receiving NIV. We present long-term all-cause mortality data from patients receiving NIV for the first time. METHOD: Data from medical records were retrospectively retrieved from all patients receiving NIV for the first time after being admitted acutely to an acute medical ward and further transfer to a respiratory ward with respiratory failure and a diagnosis of COPD in the period January 1, 2005 to December 31, 2007; patients were followed until January 2012. Demographic data collected included age, sex, diagnoses at discharge, and, when present, FEV(1); a “not-to-intubate” order was also registered when listed. RESULTS: In total, 253 patients (143 female, 110 male) received NIV for the first time. The median age was 72 years (range 46–91 years). The 30-day mortality rate was 29.3%. The 5-year survival rate was 23.7%. Women showed a trend towards better survival than men (25.7% vs 19.2%, P = 0.25), and the trend was even more pronounced for patients with COPD. CONCLUSION: The mortality rate of patients receiving NIV is high, as expected in a real-life setting, but with a 5-year survival rate of 23.7% with a trend towards more female than male long-term survivors

Gastro- or Duodenojejunostomy Leaks After Pancreatoduodenectomy: Single Center Experience and Narrative Literature Review

Background and Methods - Gastro- or duodenojejunostomy leaks after pancreatoduodenectomy is rare. This study aims to analyze the incidence, management, and outcome of gastro- or duodenojejunostomy leaks after pancreatoduodenectomy based on a single center experience from 2004 to 2020 with a narrative literature review. Results - Of a total of 1494 pancreatoduodenectomies, eight patients with gastrojejunostomy (n=1) or duodenojejunostomy (n=7) leak were identified from the institutional pancreatic database. All leaks were treated operatively. In two patients dismantling of the duodenojejunostomy, distal gastrectomy, and closure of the pyloric and jejunal side, a percutaneous endoscopic gastrostomy and a feeding jejunostomy ultimately had to be performed after an unsuccessful attempt of gastrojejunostomy and suture of the duodenojejunostomy, respectively. The literature search revealed three more studies specifically addressing this complication after pancreatoduodenectomy (36 patients of a total of 4739 pancreatoduodenectomies). Based on an analysis of the current study and the literature review, the overall incidence of gastro- or duodenojejunostomy leaks after pancreatoduodenectomy was 0.71 % (44/6233 pancreatoduodenectomies). The occurrence of a gastro- or duodenojejunostomy leak was associated with a concomitant postoperative pancreatic fistula in 50 % of the cases, an increased length of hospital stay, and a mortality rate of 15.9 %. Surgical treatment was performed in 84 % of the cases. Conclusion - Gastro- or duodenojejunostomy leak is a rare complication after pancreatoduodenectomy. Prompt diagnosis and early repair is important. In most cases, a surgical intervention is necessary for a good outcome. Under salvage conditions, a bailout strategy may be to temporarily dismantle the gastro- or duodenojejunal anastomosis

Pseudomonas aeruginosa contamination of mouth swabs during production causing a major outbreak

BACKGROUND: In 2002 we investigated an outbreak comprising 231 patients in Norway, caused by Pseudomonas aeruginosa and linked to the use of contaminated mouth swabs called Dent-O-Sept. Here we describe the extent of contamination of the swabs, and identify critical points in the production process that made the contamination possible, in order to prevent future outbreaks. METHODS: Environmental investigation with microbiological examination of production, ingredients and product, molecular typing of bacteria and a system audit of production. RESULTS: Of the 1565 swabs examined from 149 different production batches the outbreak strain of P. aeruginosa was detected in 76 swabs from 12 batches produced in 2001 and 2002. In total more than 250 swabs were contaminated with one or more microbial species. P. aeruginosa was detected from different spots along the production line. The audit revealed serious breeches of production regulations. Health care institutions reported non-proper use of the swabs and weaknesses in their purchasing systems. CONCLUSION: Biofilm formation in the wet part of the production is the most plausible explanation for the continuous contamination of the swabs with P. aeruginosa over a period of at least 30 weeks. When not abiding to production regulations fatal consequences for the users may ensue. For the most vulnerable patient groups only documented quality-controlled, high-level disinfected products and items should be used in the oropharynx
