Adaptive Lung Ventilation (ALV) Evaluierung eines neuen closed loop-gesteuerten Beatmungsalgorithmus bei Eingriffen in �berstreckter Seitenlage
1996
The lateral decubitus position is the standard position for nephrectomies. There is a lack of data about the effects of this extreme position upon respiratory mechanics and gas exchange. In 20 patients undergoing surgery in the nephrectomy position, we compared a new closed-loop-controlled ventilation algorithm, adaptive lung ventilation (ALV), which adapts the breathing pattern automatically, to the respiratory mechanics with conventionally controlled mandatory ventilation (CMV). The aims of our study were (1) to describe positioning effects on respiratory mechanics and gas exchange, (2) to compare ventilatory parameters selected by the ALV controller with traditional settings of CMV, and …
Exceptional LAS Requests in Eurotransplant: Analysis of an 8-year Effort to Improve Lung Allocation for Precarious Patients
2020
PURPOSE: Following introduction of the lung allocation score (LAS) in 2011, Eurotransplant member centers can apply for an exceptional LAS (eLAS) if the calculated LAS insufficiently reflects the perceived transplant benefit for a patient, specifically in case of primary pulmonary hypertension group 1 and 4; combined lung+non-renal transplantation; rare diseases; or extracorporeal support. Each eLAS proposal is evaluated by a LAS Review Board, consisting of ≥3 lung transplant experts, which subsequently declines or approves the eLAS request in consensus of ≥3 votes. In case of a lower than accepted score, predefined business rules to assign LAS percentiles are used. METHODS: A retrospective…
Genome-wide association analysis identifies six new loci associated with forced vital capacity
2014
Forced vital capacity (FVC), a spirometric measure of pulmonary function, reflects lung volume and is used to diagnose and monitor lung diseases. We performed genome-wide association study meta-analysis of FVC in 52,253 individuals from 26 studies and followed up the top associations in 32,917 additional individuals of European ancestry. We found six new regions associated at genome-wide significance (P <5 x 10(-8)) with FVC in or near EFEMP1, BMP6, MIR129-2-HSD17B12, PRDM11, WWOX and KCNJ2. Two loci previously associated with spirometric measures (GSTCD and PTCH1) were related to FVC. Newly implicated regions were followed up in samples from African-American, Korean, Chinese and Hispani…
