Associations of Sedentary Behavior and Screen Time with Human Gut Microbiome Composition and Diversity
Human gut microbiome richness, diversity, and composition are associated with physical activity and impaired glycemic control; however, the associations with sedentary behavior and screen time are not as well-established. This study evaluated associations of sedentary behavior and screen time with the alpha diversity and composition of the human gut microbiome in adults with and without impaired glycemic control. Sedentary behavior and screen time data were collected via survey from 47 adults (38% with impaired glycemic control). Microbiome composition and alpha diversity were determined in fecal microbial DNA. Sedentary behavior was negatively associated with the number of observed operational taxonomic units (OTUs), Chao 1 Index, and Fisher’s Alpha Index. These associations were slightly attenuated but remained significant when controlling for covariates. Screen time was negatively associated with the number of observed OTUs, Shannon Index, and Fisher’s Alpha Index; however, only the association with observed OTUs was independent of all covariates. Our findings suggest sedentary behavior and screen time may be significant influencers of compositional changes in human gut microbiota. This may be a potential mechanism linking sedentary behavior and screen time to an increased risk of type 2 diabetes
High-Resolution Taxonomic Characterization Reveals Novel Human Microbial Strains with Potential as Risk Factors and Probiotics for Prediabetes and Type 2 Diabetes
Alterations in the composition of the gut microbiota is thought to play a key role in causing type 2 diabetes, yet is not fully understood, especially at the strain level. Here, we used long-read DNA sequencing technology of 16S-ITS-23S rRNA genes for high-resolution characterization of gut microbiota in the development of type 2 diabetes. Gut microbiota composition was characterized from fecal DNA from 47 participants divided into 4 cohorts based on glycemic control: normal glycemic control (healthy; n = 21), reversed prediabetes (prediabetes/healthy; n = 8), prediabetes (n = 8), or type 2 diabetes (n = 10). A total of 46 taxa were found to be possibly related to progression from healthy state to type 2 diabetes. Bacteroides coprophilus DSM 18228, Bifidobacterium pseudocatenulatum DSM 20438, and Bifidobacterium adolescentis ATCC 15703 could confer resistance to glucose intolerance. On the other hand, Odoribacter laneus YIT 12061 may be pathogenic as it was found to be more abundant in type 2 diabetes participants than other cohorts. This research increases our understanding of the structural modulation of gut microbiota in the pathogenesis of type 2 diabetes and highlights gut microbiota strains, with the potential for targeted opportunistic pathogen control or consideration for probiotic prophylaxis and treatment
Ausbildungskonzept und Notfallalgorithmus für Rettungskräfte bei Kindern mit Kunstherzunterstützungssystemen
Einleitung
Miniaturisierte Herzunterstützungspumpen, sog. Kunstherzsysteme oder „ventricular assist devices“ (VADs) bieten die Möglichkeit, diese Systeme im Kindesalter anzuwenden. Durch die lange Wartezeit auf ein geeignetes Spenderorgan sollte bei Kindern, unterstützt mit einem intrakorporealen VAD, die Entlassung nach Hause angestrebt werden. Schwerpunkte vor einem Spitalaustritt sind neben der adäquaten Schulung und Aufklärung des Patienten und deren Familie auch ein Ausbildungs- und Schulungskonzept für die lokalen Rettungskräfte und die Betreuungspersonen vor Ort.
Methoden
Es wird ein auf die präklinische Versorgung abgestimmter Notfallalgorithmus für die Erstversorgung von VAD-Patienten vorgestellt sowie das gemeinsam erarbeitete Ausbildungskonzept der lokalen Rettungskräfte und des Kinderspitals Zürich. Schwerpunkte des Schulungsprogramms sind neben der theoretischen Einführung praktische Workshops, „cardiac arrest simulation training“ (CAST) sowie die Erstellung eines genau definierten Alarmierungsplans unter Einbezug der lokalen ärztlichen Organisationsstrukturen und der Spezialisten des Kinderspitals.
Schlussfolgerung
Die Besonderheiten bei der Versorgung von Kindern am VAD werden vorgestellt und diskutiert
