The new COVID-19 pandemic has an impact on routine thoracic surgery. Various concepts and recommendations are being pursued to protect patients and hospital staff. However, the implementation of these recommendations may depend on the existing infrastructure, local conditions and in-house procedural instructions. Between 11th May and 26th May 2020, an anonymous online survey on the topic of COVID-19 was conducted among thoracic surgeons in Germany. The survey consisted of 16 questions on the local COVID-19 case numbers, protective measures, procedural instructions and treatment concepts. selleck chemicals The results were summarised, descriptively analysed and discussed. The response rate of 42.6% (n = 66), included replies from 23 (34.8%) specialised hospitals, 18 (27.3%) maximum care hospitals and 14 (21.2%) university clinics. COVID-19-positive patients were treated in 65 (99%) clinics and 37.9% of the clinics also performed surgery on COVID-19-positive patients. Nasopharyngeal swabs were the main instrument for COVID-19 patient testing (in 95.4% of the clinics). Test results influenced decisions on treatment in 71.2% of the clinics. In 59.1% of clinics, safety equipment was supplemented with FFP2 masks and eye protection during thoracic surgeries due to the COVID-19 pandemic. Almost all thoracic surgeons reported that they had treated patients with COVID-19 and half of them also had performed surgery on COVID-19-positive patients. The applied procedural instructions as well as the effects of COVID-19 on treatment decisions and patient-doctor contact differed between the reporting clinics.Almost all thoracic surgeons reported that they had treated patients with COVID-19 and half of them also had performed surgery on COVID-19-positive patients.

Cardiac insufficiency is a major morbidity in neonatal hyperthyroidism. It is important to assess the hemodynamics in neonates born to mothers with Graves' disease (GD). This study prospectively evaluated the hemodynamic changes in neonates born to mothers with GD. Overall, 80 newborns were enrolled. Thirty-six neonates were born to mothers with GD who were positive for thyroid-stimulating hormone (TSH) receptor antibody (TRAb), and 44 were born to mother negative for TRAb. The serum levels of TSH, free triiodothyronine (FT ), free thyroxine (FT ), and N-terminal-pro-B-type natriuretic peptide (NT-proBNP), the cardiac output, and cardiac index (CI) evaluated by echocardiography were compared between the two groups at several postnatal points (day of delivery and 5, 10, and 30 days of life). The TRAb-positive newborns had higher FT levels and CI on Day 5 (both p < 0.05) and higher FT (p < 0.05) and FT levels (p < 0.01) and CI (p < 0.01) but lower TSH levels (p < 0.05) on Day 10 than the TRAb-negative newborns. The TRAb-positive newborns had significantly higher NT-proBNP levels on Days 5 (median 752 vs. 563 pg/mL, p = 0.034) and 10 (median 789 vs. 552 pg/mL, p = 0.002) than the TRAb-negative newborns. Hemodynamic changes in neonates born to TRAb-positive mothers with GD resulted in a higher CI and NT-proBNP levels than in those with TRAb-negative mothers from postnatal days 5 to 10.Hemodynamic changes in neonates born to TRAb-positive mothers with GD resulted in a higher CI and NT-proBNP levels than in those with TRAb-negative mothers from postnatal days 5 to 10. The aim of this study was to evaluate the impact of short-term therapeutic hydrocortisone intake on pituitary and adrenal function in healthy young male subjects. Ten physically active men received 50 mg/per day of hydrocortisone at 800 a.m. for 5 days. Cortisol, DHEA, and ACTH concentrations in plasma, and cortisol and DHEA concentrations in saliva were determined the week before, just before (800 a.m.) and 2 h after (1000 a.m.) drug ingestion on days 1, 3, and 5 of treatment and day 1 post treatment. Hydrocortisone intake induced a significant increase in both plasma cortisol (×3) and saliva cortisol (×10) concentrations 2 h after administration. Plasma and saliva DHEA concentrations were significantly decreased, as were plasma ACTH concentrations, 2 h after administration, with an increase in the cortisol/DHEA and cortisol/ACTH ratios. However, no change in cortisol, DHEA, ACTH, cortisol/DHEA, or cortisol/ACTH was observed 24 h after the last intake during treatment or post treatment, except for a domate adrenal and pituitary function. To investigate the status of preoperative anterior pituitary function in patients undergoing pituitary adenoma (PA) resection and to identify factors associated with preoperative anterior pituitary dysfunction (APD). Patients with functioning and nonfunctioning PAs who underwent pituitary adenoma resection for first time, from January 2009 to December 2019 were analyzed. Total sample included 232 patients; 123 (53.2%) females, mean age at diagnosis was 53.3 years. Sixty-three percent presented as nonfunctioning PAs and 37.1% as functioning PAs. Eighty-eight percent were macroadenomas and 34.9% had cavernous sinus invasion. APD was demonstrated in 36.2% (n = 84) of the patients. The FSH/LH deficit was the most frequent anterior pituitary deficit (31.9%); followed by ACTH (18.1%); TSH (16.4%) and GH (13.8%). We identified as independent risk factors of APD, male sex (OR = 6.1, 95% CI = 3.3-11.0); age (OR = 1.03 for each year, 95% CI = 1.01-1.04), diabetes mellitus (OR = 3.5, 95% CI = 1.63-7.69), pituitaryarefully assessed.It is necessary to determine an environmentally friendly method of reusing the vast amount of coal waste that is generated during coal preparation. This study evaluates the applicability of using weathered coal waste in a permeable reactive barrier to prevent groundwater contamination. Coal waste, with different weathering degrees, was obtained from two coal mining sites in South Jeolla Province, Korea. The reactivities of the coal waste with inorganic contaminants, such as copper, cadmium, and arsenic, were examined in batch and column experiments. The batch experiment results indicate that the coal waste removal efficiencies of copper (99.8%) and cadmium (95.4%) were higher than those of arsenic (71.0%). The maximum adsorption capacities of coal waste for copper, cadmium, and arsenic calculated from the Langmuir isotherm model were 4.440 mg/g, 3.660 mg/g, and 0.718 mg/g, respectively. The equilibrium of adsorption was attained within 8 h. The column experiment results reveal that the coal waste effectively removed inorganic contaminants under flow-through conditions.
