The FLUXNET2015 dataset and the ONEFlux processing pipeline for eddy covariance data

The FLUXNET2015 dataset provides ecosystem-scale data on CO2, water, and energy exchange between the biosphere and the atmosphere, and other meteorological and biological measurements, from 212 sites around the globe (over 1500 site-years, up to and including year 2014). These sites, independently managed and operated, voluntarily contributed their data to create global datasets. Data were quality controlled and processed using uniform methods, to improve consistency and intercomparability across sites. The dataset is already being used in a number of applications, including ecophysiology studies, remote sensing studies, and development of ecosystem and Earth system models. FLUXNET2015 includes derived-data products, such as gap-filled time series, ecosystem respiration and photosynthetic uptake estimates, estimation of uncertainties, and metadata about the measurements, presented for the first time in this paper. In addition, 206 of these sites are for the first time distributed under a Creative Commons (CC-BY 4.0) license. This paper details this enhanced dataset and the processing methods, now made available as open-source codes, making the dataset more accessible, transparent, and reproducible.Peer reviewe

Successful resection of oesophageal adenocarcinoma 16 years after heart transplantation—a case report

Introduction: With improving results of heart transplantation and subsequently increasing survival, long-term complications such as neoplastic malignancies are more often being discovered. Presentation of case: In this report, we present a unique case of successful oesophagus resection with gastric pull-up, on a heart-transplanted patient diagnosed with oesophageal adenocarcinoma. Discussion: With the growing number of long-term surviving heart transplanted patients, the number of neoplasia in this patient-group will subsequently grow. Since physical condition and quality of life in long-term surviving heart transplanted patients is comparable to the general population, and since surgical treatment remains the mainstay of treatment for localised oesophageal carcinoma in non-heart transplanted patients, a larger subgroup of heart transplanted patients will most likely be considered for cancer surgery. Conclusion: Our case demonstrates the possibility of operating on the heart transplanted patient-group, and supports the option, that well-managed heart transplantation not should be a limiting factor, when deciding whether a patient is a candidate for surgical intervention or not

Routine postoperative chest X-ray is unnecessary following the Nuss procedure for pectus excavatum

OBJECTIVES: Pneumothorax is the most common complication after the Nuss procedure for pectus excavatum. The majority of pneumothoraces are small, and the patients have no symptoms. The aim of this study was to evaluate the necessity for routine chest X-ray immediately after surgery. METHODS: Group I consists of 644 patients who were operated on with a Nuss procedure for pectus excavatum between 2001 and 2009 (85% male, median age 16 [range 7–48 years]) at Aarhus University Hospital. The standard procedure included chest X-ray immediately after surgery and before discharge. Group II consists of 294 patients (88% male, median age 16 [range 11–54 years]) who had a Nuss procedure in the period January 2011 to October 2012, where the standard procedure only included chest X-ray before discharge. RESULTS: In Group I, pneumothorax was found on the chest X-ray obtained immediately after surgery in 333 (52%) patients. Fifteen (4.5%) were treated with chest-tube drainage. Six of these patients had no symptoms, but a 2- to 3-cm pneumothorax, 2 had progression of the pneumothorax and 7 had respiratory symptoms. The median size of those drained was 3 (range 2–6 cm). At the normal 6-week control, no pneumothorax remained. Group II: Among the 294 patients, 1 (0.3%) had a chest tube. CONCLUSIONS: Only patients with respiratory symptoms after the Nuss procedure need a chest X-ray. A routine chest X-ray can be limited to the time of discharge where the position of the bar(s) is also checked
