Diagnostic species are crucial for the functioning of plant associations in inland salt marshes.

Salt marsh vegetation is considered unique and valuable and has been legally protected in Europe for years but is still declining. Its protection is related to vegetation syntaxonomical units. The characteristic combination of diagnostic species is used to create this syntaxonomical system.

The utility of airborne hyperspectral and satellite multispectral images in identifying Natura 2000 non-forest habitats for conservation purposes.

Aerial hyperspectral and multispectral satellite data are the two most commonly used datasets to identify natural and semi-natural vegetation. However, there is no documented analysis based on data from several areas concerning the difference in the classification accuracy of non-forest Natura 2000 habitat with the use of aerial hyperspectral and satellite multispectral data. Also, there is no recommendation, on which habitat can be classified with sufficient accuracy using free multispectral images.

Vegetation of temperate inland salt-marshes reflects local environmental conditions.

Inland salt marshes are recognized as habitats of unique and valuable vegetation at the European scale. There is still a lack of generalization regarding its vegetation syntaxonomy and environmental requirements, which is needed for its effective protection. To falsify our hypothesis about vegetation dependence on environmental requirements we aimed at description of the syntaxonomical units present in temperate European inland salt marshes and identification of their main environmental drivers.

Invasive Plant Species Distribution Is Structured by Soil and Habitat Type in the City Landscape.

Invasive alien species (IAS) is a global problem that largely relates to human activities and human settlements. To prevent the further spread of IAS, we first need to know their pattern of distribution, to determine which constitutes the greatest threat, and understand which habitats and migration pathways they prefer. Our research aimed to identify the main vectors and distribution pattern of IAS of plants in the city environment.

The influence of comorbidities on mortality in sarcoidosis: a observational prospective cohort study.

Aim: The aim of this study was to identify the frequency and prevalence of comorbidities in sarcoid patients and to assess their influence on overall mortality in the cohort of patients with sarcoidosis.

Materials And Methods: A cohort of 557 patients with histologically confirmed sarcoidosis diagnosed between 2007 and 2011 and a group of non-sarcoid controls were observed. All patients were carefully observed for comorbidities and mortality.

Methotrexate as a single agent for treating pulmonary sarcoidosis: a single centre real-life prospective study.

Introduction: The first-line therapy in chronic sarcoidosis, according to WASOG/ATS/ERS recommendations, is GCS. This therapy is associated with significant adverse effects and finally does not alter the natural history of the disease. The objective of our study was to evaluate the efficacy and safety of monotherapy with MTX, as an alternative to GCS, in progressive pulmonary sarcoidosis.

Fatal clinical outcome in a patient with sarcoidosis-lymphoma syndrome.

A 62-year-old female suspected of malignant disease underwent a splenectomy that revealed noncaseating granulomas in the histological specimen. Chest X-ray (CXR) and lung CT scans suggested sarcoidosis stage II. TBLB showed noncaseating granulomas.

Impact of mild anaemia on dyspnoea during exertion and exercise tolerance in patients with acute exacerbation of chronic obstructive pulmonary disease.

Introduction: Dyspnoea and decreased exercise tolerance are symptoms of acute exacerbation of chronic obstructive pulmonary disease (AECOPD). Anaemia is a risk factor for reduced functional capacity and dyspnoea in stable COPD. There is limited information about the impact of anaemia on functional capacity and dyspnoea of patients during AECOPD.

[Autoimmunological pulmonary alveolar proteinosis--case report].

Autoimmunological pulmonary alveolar proteinosis (APAP) is a rare interstitial lung disease with abnormal surfactant homeostasis. Autoimmunological pulmonary alveolar proteinosis is diagnosed most often in the third or fourth decade of life. Predominant symptoms are dyspnea and cough.

[The impact of comorbidities on the length of hospital treatment in patients with chronic obstructive pulmonary disease].

Introduction: The aim of this study was to assess relationships of chronic obstructive pulmonary disease (COPD) comorbidities number, with the duration of hospital stay due to acute AE COPD in longitudinal prospective study.

Material And Methods: We evaluated the number of re-hospitalizations, length of stay and number of comorbidities in 464 consecutive COPD patients admitted to the tertiary respiratory hospital due to AE COPD enrolled in longitudinal prospective study from 2005 to 2009 year.

Results: GOLD II stage COPD patients had 4.

[The variability of clinical presentation of chronic obstructive pulmonary disease in patients with hereditary alpha-1 antitrypsin deficiency].

Four patients with alpha-1 antitrypsin (alpha-1 AT) deficiency are presented: one woman with severe (phenotype PiZ) and 3 men with moderate (phenotype PiMZ) deficiency of alpha-1 AT. The variability of clinical presentation of hereditary emphysema is described. In all patients tobacco smoking history, spirometric and 6-minutes walking tests as well as HRCT of the lung were performed and compared.

[Restless legs syndrome and periodic limb movements during sleep in a patient with obstructive sleep apnea].

A case of moderate obstructive sleep apnea in which effective treatment with continuous positive airway pressure did not reduce excessive daytime sleepiness was described. Polysomnography with tibial muscles activity recording revealed frequent periodic limb movements in sleep (PLMS) with sleep fragmentation. PLMS index was 13.
