In conclusion, we showed that androgen deficiency enhances Dkk2 expression and secretion in the muscles of mice. Dkk2 might be involved in androgen deficiency-induced muscle wasting and osteopenia as a myokine linking muscle to bone.The new concept of thrombosis associated with an inflammatory process is called thromboinflammation. Indeed, both thrombosis and inflammation interplay one with the other in a feed forward manner amplifying the whole process. This pathological reaction in response to a wide variety of sterile or non-sterile stimuli eventually causes acute organ damage. In this context, neutrophils, mainly involved in eliminating pathogens as an early barrier to infection, form neutrophil extracellular traps (NETs) that are antimicrobial structures responsible of deleterious side effects such as thrombotic complications. Although NETosis mechanisms are being unraveled, there are still many regulatory elements that have to be discovered. Micro-ribonucleic acids (miRNAs) are important modulators of gene expression implicated in human pathophysiology almost two decades ago. Among the different miRNAs implicated in inflammation, miR-146a is of special interest because (1) it regulates among others, Toll-like receptors/nuclear factor-κB axis which is of paramount importance in inflammatory processes, (2) it regulates the formation of NETs by modifying their aging phenotype, and (3) it has expression levels that may decrease among individuals up to 50%, controlled in part by the presence of several polymorphisms. In this article, we will review the main characteristics of miR-146a biology. In addition, we will detail how miR-146a is implicated in the development of two paradigmatic diseases in which thrombosis and inflammation interact, cardiovascular diseases and sepsis, and their association with the presence of miR-146a polymorphisms and the use of miR-146a as a marker of cardiovascular diseases and sepsis.Lung ultrasound is a fast and reliable diagnostic tool in the detection of a neonatal pneumothorax. This tutorial provides basic information for understanding and detecting the generated artefacts, such as A-lines, B-lines, and the lung point. Essential knowledge of these artefacts allows for rule-in and rule-out criteria of a pneumothorax diagnosis. Lung ultrasound could help to reduce the use of radiation in neonatology in the future.The logistical and infectious peculiarities and requirements challenge the intensive care treatment teams aiming at a successful liberation of patients from long-term mechanical ventilation. Especially in the pandemic, it is therefore important to use all potentials for weaning and decannulation, respectively, in patients with prolonged weaning.Weaning centers represent units of intensive medical care with a particular specialization in prolonged weaning. They are an integral part of a continuous care concept for these patients. A systematic weaning concept in the pandemic includes structural, personnel, equipment, infectiological and hygienic issues. In addition to the S2k guideline "Prolonged weaning" this position paper hightlights a new classification in prolonged weaning and organizational structures required in the future for the challenging pandemic situation. Category A patients with high weaning potential require a structured respiratory weaning in specialized weaning units, so as to get the greatest possible chance to realize successful weaning. Patients in category B with low or currently nonexistent weaning potential should receive a weaning attempt after an intermediate phase of further stabilization in an out-of-hospital ventilator unit. Category C patients with no weaning potential require a permanent out-of-hospital care, alternatively finishing mechanical ventilation with palliative support.Finally, under perspective in the position paper the following conceivable networks and registers in the future are presented 1. locally organized regional networks of certified weaning centers, 2. a central, nationwide register of weaning capacities accordingly the already existing DIVI register and 3. registration of patients in difficult or prolonged weaning.

 The relevance of undergraduate Online Teaching increases - on one hand to diversify (ENT) teaching, on the other to continue medical training even in times of crisis like the SARS-CoV-2 pandemic. Therefore, at the university hospital of Freiburg we build and launched the ENT Learning Program, an online learning platform for medical students.

 This study will give an insight into structure and functions of the learning program. Furthermore, its use and usefulness will be subjectively and objectively evaluated.

 The ENT Learning Program is a web application, that can be used by any Internet-enabled device. ENT content is presented by text, images, video tutorials and interactive features like multiple-choice questions and feedback functions. To evaluate students' use and benefits of the program we first conducted a questionnaire survey with 116medical students. To objectify the results, we then counted the actual visits to the program and carried out a randomised learning-control-study (n = 47).

 The learning program was used by 97 % of the interrogated students. Over 80 % said that the program improved their exam preparation, motivated them to study and enhanced their interest in ENT. In one year, we counted almost 90.000 visits to the website. Furthermore, the learning-control-study showed a significant better test outcome in students, who used the LP in addition.

 The ENT Learning Program is a promising tool in online teaching, that did not yet exist in Germany that way. compound library chemical Through academic collaborations it could be optimized further and integrated into ENT courses at other universities.

 The study aimed to evaluate perinatal outcomes associated with introduction of and adherence to early diabetes screening guidelines.

 Retrospective cohort study of all women who received prenatal care at a single, high-volume tertiary care center before ("preguidelines") and after ("postguidelines") American College of Obstetrics and Gynecology guidelines for early pregnancy diabetes screening for women at high risk for diabetes. Women with known pregestational diabetes, late entry to prenatal care, a fetus with a known anomaly, or multiple gestation were excluded. Multivariable linear and logistic regression models were constructed to compare maternal and neonatal outcomes between women in the preguidelines cohort to those in the postguidelines cohort. Similarly, adherence to screening guidelines was assessed, and among all women who were eligible for early diabetes screening, multivariable linear, and logistic models were created to compare outcomes between those women who were screened early to those who were not.
