Conventional and digital pleural drainage systems – advantages and disadvantages
Introduction: Pleural cavity drainage is a crucial component of the surgical management of patients with various chest diseases. Digital drainage systems are increasingly used in contemporary thoracic surgical procedure, which is likely a result of their effectiveness in achieving early postoperative ambulation, cutting down on hospital stays and lowering costs. The vast majority of thoracic surgeons worldwide prefer digital drainage systems to traditional ones. The advantages of the former, however, are disputed by some researchers. Aim: The objective of this study was to compare the two types of pleural drainage mechanisms, conventional and digital, in terms of duration of pleural drainage in days, financial cost, and postoperative air leak duration. Materials and methods: The study focused on 80 patients who underwent various thoracic surgical interventions in the Clinic of Thoracic and Abdominal Surgery at St George University Hospital in Plovdiv. They were divided into two groups: group 1 consisted of 42 patients who were postoperatively attached to a conventional non-mobile pleural drainage system, and group 2 consisted of 38 patients in whom a mobile digital pleural drainage system was used. The main analyzed data were duration of pleural drainage, duration of postoperative air leak, hospital stay, and financial costs. Results: The average duration of pleural drainage, regardless of surgery and type of drainage system applied was 4.86±0.8 days. The average duration of pleural drainage in patients attached to the mobile digital drainage system was shorter than that in patients with a conventional pleural non-mobile drainage system, regardless of the type of surgery done. This difference was statistically significant in favor of the digital pleural drainage system. The study also found a statistically significant difference in terms of financial costs in favor of digital draining system. The average cost of a hospital stay for patients attached to a mobile digital drainage system was BGN 119.40±7.15, whereas the average cost of a hospital stay for patients connected to a traditional pleural drainage system (PDS) was BGN 159±10.50. Regarding the duration of postoperative air leak, the difference between the types of pleural drainage mechanism used was not convincing. Conclusions: Digital pleural drainage systems provide clinicians with an opportunity to assess the postoperative air leak more precisely, track its dynamics, shorten hospital stays, reduce postoperative costs, and optimize the time to remove the chest drain. Based on these features, they will undoubtedly continue to enter everyday surgical practice
Balkan Vegetation Database (BVD) – updated information and current status
The Balkan Vegetation Database (BVD; GIVD ID: EU-00-019) is a regional database, which was established in 2014. It comprises phytosociological relevés covering various vegetation types from nine countries of the Balkan Peninsula (Albania – 153 relevés, Bosnia and Herzegovina – 1715, Bulgaria – 12,282, Greece – 465, Croatia – 69, Kosovo – 493, Montenegro – 440, North Macedonia – 13 and Serbia – 2677). Currently, it contains 18,306 relevés (compared to 9.580 in 2016), and most of them (82.8%) are geo-referenced. The database includes both digitized relevés from the literature (65.6%) and unpublished data (34.5%). Plot size is available for 84.7% of all relevés. During the last four years some “header data information” was improved e.g. elevation (now available for 83.4% of all relevés), aspect (67.7%), slope (66%), total cover of vegetation (54.3%), cover of tree, shrub, herb, bryophyte and lichen layers (27.1%, 20.1%, 40.2%, 11.5% and 2.1%), respectively. Data access is either semi-restricted (65.6%) or restricted (34.4%). Most relevés (84.6%) are classified to syntaxa of different levels. The database has been used for numerous studies with various objectives from floristic, vegetation and habitat-related topics, to macroecological studies at the local, regional, national, continental and global levels. During the last four years, BVD data were requested from 111 different projects via the EVA and sPlot databases
Balkan Vegetation Database: historical background, current status and future perspectives
The Balkan Vegetation Database (BVD; GIVD ID: EU-00-019; http://www.givd.info/ID/EU-00- 019) is a regional database that consists of phytosociological relevés from different vegetation types from six countries on the Balkan Peninsula (Albania, Bosnia and Herzegovina, Bulgaria, Kosovo, Montenegro and Serbia). Currently, it contains 9,580 relevés, and most of them (78%) are geo-referenced. The database includes digitized relevés from the literature (79%) and unpublished data (21%). Herein we present descriptive statistics about attributive relevé information. We developed rules that regulate governance of the database, data provision, types of data availability regimes, data requests and terms of use, authorships and relationships with other databases. The database offers an extensive overview about studies on the local, regional and SE European levels including information about flora, vegetation and habitats
