mployees with CMD can be supported by more collaborative and work-related interventions. However, they also reveal limits and barriers of existing interventions and therefore provide useful hints for their further development and dissemination.The ongoing COVID-19 pandemic has caused significant morbidity and mortality worldwide, as well as profound effects on society. COVID-19 patients have an increased risk of thromboembolic (TE) complications, which develop despite pharmacological thromboprophylaxis. The mechanism behind COVID-19-associated coagulopathy remains unclear. Mannose-binding lectin (MBL), a pattern recognition molecule that initiates the lectin pathway of complement activation, has been suggested as a potential amplifier of blood coagulation during thromboinflammation. Here we describe data from a cohort of critically ill COVID-19 patients (n = 65) treated at a tertiary hospital center intensive care unit (ICU). A subset of patients had strongly elevated MBL plasma levels, and activity upon ICU admission, and patients who developed symptomatic TE (14%) had significantly higher MBL levels than patients without TE. MBL was strongly correlated to plasma D-dimer levels, a marker of COVID-19 coagulopathy, but showed no relationship to degree of inflammation or other organ dysfunction. In conclusion, we have identified complement activation through the MBL pathway as a novel amplification mechanism that contributes to pathological thrombosis in critically ill COVID-19 patients. Pharmacological targeting of the MBL pathway could be a novel treatment option for thrombosis in COVID-19. Laboratory testing of MBL levels could be of value for identifying COVID-19 patients at risk for TE events.Seit Mitte Mai wird berichtet, dass die Maßnahmen oder die Angst vor einer Infektion mit SARS-CoV-2 zu einem sekundären Gesundheitsrisiko führen könnten, weil Diagnosen, z. B. von Krebs- oder Herz-Kreislauferkrankungen, verspätet gestellt und Therapien, z. B. komplizierte operative Eingriffe mit Intensivpflege, verzögert durchgeführt werden (COVIDSurg Collaborative, Br J Surg 2020; DOI 10.1002/bjs.11746; Kuhlen R et al., Dtsch Arztebl Int 2020; 117 488-489). In der Kinder- und Jugendmedizin stehen die Fragen und Probleme des Schulunterrichts, der fehlenden sozialen Kontakte innerhalb der peer group und der häuslichen Gewalt im Vordergrund der Fragen zur Auswirkung der Pandemie auf die Gesundheit (Wade M et al., Psychiatry Res 2020; 290113-143). Mögliche Auswirkungen auf die Umsetzung der Richtlinie des Gemeinsamen Bundesausschuss (G-BA) über die Früherkennung von Krankheiten bei Kinder (Vorsorge-Untersuchungen U1-U9) sind bislang nicht bekannt. Im Rahmen der SARS-CoV2 Kontaktbeschränkungen hatte der G-BA die Toleranzzeiten (Abrechnungsfristen) für die Vorsorge-Untersuchungen U6-U9 bis zum Ablauf von 3 Monaten nach Beendigung einer epidemischen Lage von nationaler Tragweite aufgehoben (BAnz AT 29.05.2020 B6).
   Collaboration has been shown to be beneficial when we have complex problems and highly specialized groups, such as in head and neck reconstruction. Otolaryngology, plastic surgery, and oral maxillofacial surgeons perform head and neck reconstruction research. While the specialties represent unique backgrounds, the degree of interdisciplinary collaboration and subtopic focus is unknown. We sought to describe the frequency of interinstitutional interdisciplinary collaboration and examine the association of specialty with research subtopics.
 
   Oral presentations from 2014 to 2018 focused on head and neck reconstruction or associated principles at the main reconstructive academic meetings in otolaryngology (American Head and Neck Society), plastic surgery (American Society for Reconstructive Microsurgery), and oral maxillofacial surgery (American Association of Oral and Maxillofacial Surgeons) were reviewed. Author specialty and institution data were recorded. All abstracts were assigned a research subtopic, chosen based on identified themes.  https://www.selleckchem.com/products/BIBF1120.html  Subtopic frequencies among the specialties were compared.
 
   Thirteen of 88 (15%) US institutions participate in interdisciplinary collaboration in head and neck reconstruction research. Of the remaining institutions, 23 (31%) have researchers performing parallel work and not collaborating. Certain research subtopics were more often presented by each specialty, representing differing interests.
 
   Collaboration among head and neck reconstruction research at the US institutions is low compared with the potential. Specialties focus on different research subtopics, and therefore can benefit from working together.

   Although microsurgery fellowships have existed since the 1980s, there is no established curriculum. Microsurgery fellowships vary greatly in clinical caseload, case diversity, and training resources, and there is no consensus on the appropriate composition of a microsurgery fellowship. This study surveys fellowship directors (FD) and recent microsurgery fellows (MFs), graduates, to describe the ideal microsurgery fellowship program.
 
   A 15-item questionnaire was sent to 38 FDs and 90 recent microsurgery fellowship graduates. This questionnaire addressed program attributes, case volumes and compositions, ideal experiences, and time allocation to different fellowship experiences. Data were analyzed using descriptive statistics, 
  -tests, and Chi-squared tests.
 
   The FD and MF surveys had a response rate of 47 and 49%, respectively. Both MF and FD agreed that exposure to microsurgical breast reconstruction is the most important characteristic of a microsurgery fellowship (
   = 0.94). MF ranked replantation on making.
   Venous congestion is the most common perfusion-related complication of deep inferior epigastric artery perforator (DIEP) flap. Several hydraulic constructs can be created for venous superdrainage in case of flap venous engorgement or as a preventive measure. These can be classified based on the choice of the draining vein of the flap, either a second deep inferior epigastric vein (DIEV) or a superficial inferior epigastric vein (SIEV), and of the recipient vein, either a vein of the chest or the DIEV.
 
   We conducted a comprehensive systematic literature review in Medline, Scopus, EMBASE, Cochrane Library, and Google Scholar to find publications that reported on venous congestion in DIEP flap. The keywords used were DIEP Flap, breast reconstruction, venous congestion, supercharging, superdrainage, SIEV, and DIEV.
 
   Based on the studies found in the literature, we developed an algorithm to guide the surgeon's decision when choosing the veins for the superdrainage anastomosis.
 
   Several alternatives for venous anastomosis in superdrainage are available.
