Objective: To evaluate the COVID-19 vaccination status and related characteristics of Turkish healthcare workers practicing chest ***: A cross-sectional online survey was conducted among the Turkish Thoracic Society members. The survey was started on may 17, 2021, and kept open for seven weeks. The 39-item survey included the COVID-19 vaccination status and demographic, clinical, and occupational characteristics. Results: Of 378 healthcare workers participated in the survey, 354(93.7%) reported receiving at least one dose of the COVID-19 vaccine. A total of 323(91.2%) healthcare workers received CoronaVac vs. BioNTech/Pfizer in 31(8.8%). In the CoronaVac group, 77(23.8%) contracted COVID-19 when not fully vaccinated, and 13(4.0%) when fully vaccinated;however, 16(51.6%) healthcare workers in the BioNTech/Pfizer group got COVID-19 when not fully vaccinated, but any fully vaccinated participants did not contract COVID-19(P=0.003). Regarding vaccine dosing, 328(86.8%) were fully vaccinated, while 50(13.2%) were not. multiple regression analysis for being a non-fully vaccinated healthcare worker demonstrated a significant relationship with having any SARS-CoV-2 infection history(adjusted OR 9.57, 95% CI 3.93-23.26, Pme working at the time of survey(adjusted OR 0.13, 95% CI 0.03-0.56, P=0.006). Conclusions: Although a majority of healthcare workers were fully vaccinated, occupational and non-occupational characteristics were related to being non-fully vaccinated. Active surveillance regarding the COVID-19 vaccination in healthcare workers is necessary to address specific parameters as barriers to vaccination.

Background The nationally determined contribution（NDC） presented by Argentina within the framework of the Paris Agreement is aligned with the decisions made in the context of the United Nations Framework Conven-tion on Climate Change（UNFCCC） on the reduction of emissions derived from deforestation and forest degradation, as well as forest carbon conservation（REDD+）. In addition, climate change constitutes one of the greatest threats to forest biodiversity and ecosystem services. However, the soil organic carbon（SOC） stocks of native forests have not been incorporated into the Forest Reference Emission Levels calculations and for conservation planning under cli-mate variability due to a lack of information. The objectives of this study were:（i） to model SOC stocks to 30 cm of native forests at a national scale using climatic, topographic and vegetation as predictor variables, and（ii） to relate SOC stocks with spatial–temporal remotely sensed indices to determine biodiversity conservation concerns due to threats from high inter-annual climate *** We used 1040 forest soil samples（0–30 cm） to generate spatially explicit estimates of SOC native forests in Argentina at a spatial resolution of approximately 200 m. We selected 52 potential predictive environmental covari-ates, which represent key factors for the spatial distribution of SOC. All covariate maps were uploaded to the Google Earth Engine cloud-based computing platform for subsequent modelling. To determine the biodiversity threats from high inter-annual climate variability, we employed the spatial–temporal satellite-derived indices based on Enhanced Vegetation Index（EVI） and land surface temperature（LST） images from Landsat *** SOC model（0–30 cm depth） prediction accounted for 69% of the variation of this soil property across the whole native forest coverage in Argentina. Total mean SOC stock reached 2.81 Pg C（2.71–2.84 Pg C with a probability of 90%） for a total area of 460,790 km2,

Background In many studies, obstructive sleep apnea （OSA） has been shown to be an independent risk factor for cardiovascular disease. Conversely, there are few reports establishing possible relation between OSA and venous thromboembolism （VTE）. In this study, the aim is to evaluate OSA via polysomnography in patients with pulmonary embolism and drawing the attention of clinicians to the presence of obstructive sleep apnea syndrome （OSAS） may be a risk factor for pulmonary embolism. methods Fifty consecutive patients who were diagnosed with pulmonary embolism （PE） were evaluated prospectively for OSAS. Polysomnographic examination was conducted on 30 volunteer patients. The frequency of OSAS in PE was determined and PE cases were compared to each other after being divided into two groups based on the presence of a major risk factor. Results The study consisted of a total of 30 patients （14 females and 16 males）. In 56.7% of the patients （17/30）, OSAS was determined. The percent of cases with moderate and severe OSAS （apnea hipoapnea index 〉15） was 26.7% （8/30）. Patients who had pulmonary thromboembolism （PTE） without any known major VTE risk （n=20）, were compared to patients with VTE risk factors （n=10）, and significantly higher rates of OSAS were seen （70% and 30% respectively; P=0.045）. The mean age of the group with major PE risk factors was lower than the group without major PE risk factors （52 years old and 66 years old, respectively; P=0.015）, however, weight was greater in the group with major PE risk factors （88 kg and 81 kg, respectively; P=-0.025）. By multivariate Logistic regression analysis, in the group without any visible major risk factors, the only independent risk factor for PE was OSAS （P=0.049）. Conclusions In patients with PTE, OSA rates were much higher than in the general population. moreover, the rate for patients with clinically significant moderate and severe OSA was quite high. PTE patients with OSA symptoms （not syndromes） and without known

Background It is necessary to determine the implications for managing forest stands using variable retention harvesting for maintaining carbon and for calculating the effects of different harvesting practices on above-and belowground carbon balance in forest ecosystems. In this context, forest carbon management has gained more attention among managers and policy-makers during recent years. The aim of this study was to determine carbon pool dynamics in different forest ecosystem components after variable retention harvesting(VRH) to characterize the ecological stability and quantify the recovery rate through the years-after-harvesting(YAH).methods Carbon pool compartmentalization of 14 different components was determined in 60 harvested and primary unmanaged forests during the first 18 YAH in Tierra del Fuego(Argentina). We compared them using uni-and multi-variate methods, relativizing the outputs with primary unmanaged *** We determined the effectiveness to retain carbon components in post-harvested stands under different retention strategies(aggregated vs. dispersed). The balance among carbon pool components changed between managed and unmanaged stands across the YAH, and was directly related to the impact magnitude. Aggregated retention improved the ecological stability of the harvested areas, where the below-ground components were more stable than the above-ground components. The recovery rate was directly related to the post-harvesting natural dynamics of the stands. The studied period was not enough to fully recover the C levels of primary unmanaged forests, but VRH showed advantages to increase the C pools in the managed *** Promoting VRH can improve sustainable forestry at the landscape level and in the long term, generating positive synergies with biodiversity and the provision of ecosystem services. This study provides important new insights into forest carbon management, in particular to setting standards in carbon projects and
