Effect of intraoperative support mode on circulating inflammatory biomarkers after lung transplantation surgery.

BACKGROUND: Processes that activate the immune system during lung transplantation can lead to primary graft dysfunction (PGD) or allograft rejection. METHODS: We analyzed cytokine expression profiles after reperfusion and allograft outcomes in a cohort of patients (n = 59) who underwent lung transplantation off-pump (n = 26), with cardiopulmonary bypass (CPB; n = 18), or with extracorporeal membrane oxygenation (ECMO; n = 15). Peripheral blood was collected from patients at baseline and at 6 and 72 h after reperfusion. To adjust for clinical differences between groups, we utilized a linear mixed model with overlap weighting. RESULTS: PGD3 was present at 48 or 72 h after reperfusion in 7.7% (2/26) of off-pump cases, 20.0% (3/15) of ECMO cases, and 38.9% (7/18) of CPB cases (p = 0.04). The ECMO and CPB groups had greater reperfusion-induced increases in MIP-1B, IL-6, IL-8, IL-9, IL1-ra, TNF-alpha, RANTES, eotaxin, IP-10, and MCP-1 levels than the off-pump group. Cytokine expression profiles after reperfusion were not significantly different between ECMO and CPB groups. CONCLUSION: Our data suggest that, compared with an off-pump approach, the intraoperative use of ECMO or CPB during lung transplantation is associated with greater reperfusion-induced cytokine release and graft injury.

Incidence of Difficult Laryngoscopy in Adult Congenital Heart Disease Patients: A Retrospective Cohort Study.

OBJECTIVE: To identify the incidence of difficult intubation in patients with adult congenital heart disease (ACHD) undergoing cardiac surgery or catheterization. DESIGN: A retrospective cohort study. SETTING: A single-center academic quaternary pediatric hospital. PARTICIPANTS: All patients were >18 years of age with ACHD undergoing endotracheal intubation within the Heart Center at Texas Children's Hospital between January 2012 and December 2019. INTERVENTIONS: None. MEASUREMENT AND MAIN RESULTS: A retrospective chart review was performed, including patient demographics, preoperative airway assessment and intraoperative airway management characteristics. Airways were categorized as difficult using the Pediatric Difficult Intubation registry operational definitions. For patients classified as having a difficult airway, the preoperative airway examination findings were recorded in addition to factors associated with difficult airway in the adult. The study authors identified 1,029 patients with ACHD who underwent procedures with anesthesia at their institution and were analyzed for the presence of difficult airway. In total, 878 patients were intubated, with 4.3% (n = 38) identified to have difficult airway. The presence of concomitant syndromes was greater in patients with difficult intubations and those who were not intubated compared with those who were not difficult intubations (23.7% and 17.2 v 7.5; p < 0.001), respectively. Most patients did not have typical signs associated with difficult intubation. CONCLUSIONS: The study authors identified an incidence of difficult laryngoscopy in their cohort of ACHD patients to be 4.3%. Their incidences of difficult laryngoscopy were fewer than that reported in adult patients with noncongenital heart disease. Most importantly, the risk factors associated with difficult laryngoscopy in the normal adult may be different from those presenting with ACHD, necessitating further investigation.

Inflammatory bowel disease psychological support pilot reduces inflammatory bowel disease symptoms and improves psychological wellbeing.

This prospective service evaluation aimed to determine if integrated psychological support for patients with inflammatory bowel disease (IBD) enhanced outcomes. 75 patients were assessed and treated by a specialist liaison psychiatric service between 2015 and 2017; 43 received psychiatric intervention alone, 32 were referred for psychological intervention by clinical health psychologist; 26 completed this. Pre-post data (n=15 available) included global impression, quality of life, and psychiatric and IBD symptom scores. Referrer/patient satisfaction and cost-effectiveness were retrospectively calculated. Psychological intervention led to reductions in IBD symptoms (ΔSIBD; p=0.003), alongside improvements in depression scores (ΔPHQ-9, p=0.006) and global impression (ΔCGI; p=0.046). Patient/referrer satisfaction was very high. Indicative data comparing service utilisation 1 year before and after engagement found reductions in outpatient appointments and in imaging. This small study suggests consideration of increased access to integrated psychological support services to improve outcomes and gather further evidence of efficacy.
