Background: Esophageal atresia (EA) with or without tracheoesophageal fistula (TEF) remains one of the most common gastrointestinal neonatal malformations. Even though postoperative management is standardized, it differs between hospitals and disease-associated clinical factors that may play a role in outcome have not yet been assessed in detail.
Methods: In this monocentric retrospective study, data of 43 patients with EA between 2010 and 2018 were analyzed. Analysis includes assessment of the clinical background, surgical technique, postoperative management including application of continuous muscle relaxation (CMR), influence of coagulation parameters such as factor XIII and incidence of complications.
Results: 21 patients (49%) were preterm infants with birth weights between 490 and 2840 g (median 1893 g). Only 35% (n = 15) presented without any concomitant malformations. Within the entire study population, representing Vogt II, IIIb and IIIc, we observed an association between the development of a postoperative pneumothorax and anastomotic failure (AF) (p = 0.0013). Furthermore, pneumothorax was associated with anastomotic stenosis (AS) in Vogt IIIb patients (p = 0.0129). CMR (applied since March 2017 in 7 patients in an attempt to prevent anastomotic problems due to high complication rates) and coagulation factor XIII did not significantly correlate with postoperative outcome.
Conclusion: Appearance of pneumothorax was correlated with postoperative complications. These children should be monitored carefully in closer scheduled gastroenterological follow-up esophago-gastro-duodenoscopies. CMR and factor XIII substitution did not reduce anastomotic leakage but should be tested within an enlarged study population.

Blood clots are complex structures composed of blood cells and proteins held together by the structural framework provided by an insoluble fibrin network. Factor (F)XIII is a protransglutaminase essential for stabilizing the fibrin network. Activated FXIII(a) introduces novel covalent crosslinks within and between fibrin and other plasma and cellular proteins, and thereby promotes fibrin biochemical and mechanical integrity.

Individual differences in environmental sensitivity are linked to stress-related psychiatric symptoms. In previous research, we found that high environmental sensitivity can be a risk factor for increased inflammation and gut permeability, particularly when gut microbiome diversity is low. However, the specific gut bacterial taxa involved in this interaction remain unclear.

Thrombin is the central mediator of hemostasis, where it converts fibrinogen to fibrin, activates upstream factors to promote coagulation, activates factor XIII and thrombin-activatable fibrinolysis inhibitor to stabilize fibrin, mediates anticoagulation, and modulates cellular activity via cell surface receptors. Thus, regulation of thrombin activity is essential to the hemostatic balance. Thrombin is regulated by positively charged surface domains that surround the active site.

Acquired factor XIII (FXIII) deficiency is a rare disorder that could be associated with autoimmune and malignant disorders with a high risk of bleeding. In acute leukemias, acquired FXIII deficiency has been reported and replacement of FXIII helped to control significant bleeding. Here, we report four cases of myeloid neoplasms to have acquired FXIII deficiency with interesting concomitant RUNX1 mutation in the molecular background of two patients.

The transglutaminase (TGMs) family plays a crucial role in regulating mammalian reproduction, yet its impact on poultry reproductive traits has not been extensively studied. In this study, we identified eight members of the TGMs family in chickens and examined the contributions of genetic variations of coagulation factor XIII A chain (F13A1), transglutaminase 4 (TGM4), and LOC101749664 to selective breeding in commercial layers through genetic variation response pattern analysis. Transcriptome data from various tissues of high- and low-egg-yielding Gushi chickens revealed significant positive correlations between the mRNA expression levels of TGM4 and F13A1 genes and egg production (P < 0.
