Longitudinal evaluation of major salivary gland functioning in Sjögren's disease patients in a prospective standard-of-care cohort.

OBJECTIVES: To evaluate changes in major salivary gland functioning over time using salivary gland ultrasonography (SGUS), salivary flow measurements (sialometry), and patient-reported outcome measures (PROMs) in patients diagnosed with primary Sjögren's disease (SjD). METHODS: Consecutive outpatients from the ongoing prospective REgistry of Sjögren Syndrome LongiTudinal (RESULT) cohort, all fulfilling the ACR-EULAR classification criteria for SjD, were included. SGUS images assessed with the Hocevar and OMERACT scoring system, unstimulated and stimulated whole saliva (UWS/SWS), unstimulated and stimulated submandibular/sublingual saliva (uSMSLS/sSMSLS) and parotid saliva, EULAR Sjögren's Syndrome Patient Reported Index (ESSPRI) general dryness, oral dryness, and Xerostomia Inventory were assessed at baseline (BL), 2-year (Y2) and 5-year (Y5) follow-up. RESULTS: In total, BL and Y2 data were available for 253 patients and 75 patients had already reached Y5. At group level, SGUS Hocevar (i.e., mean±SD: 22±10 at BL, 22±10 at Y2 and 23±10 at Y5), OMERACT scores, UWS, SWS and PROMs remained stable over time (all p>0.05). Slightly decreased uSMSLS (p=0.025) and sSMSLS (p=0.004) were observed at Y5. At individual patient level, a similar proportion showed an increase or decrease of ≥25% for Hocevar, UWS and SWS. At baseline, poor associations were observed between SGUS and PROMs and fair associations between sialometry and PROMs. Over time, changes in objective assessments did not correlate with changes in PROMs. CONCLUSIONS: Overall, major salivary gland functioning assessed with SGUS, sialometry and PROMs did not change significantly up to 5 years of follow-up in a standard-of-care cohort of SjD patients from daily clinical practice.

Structured review of post-cardiotomy extracorporeal membrane oxygenation: part 1-Adult patients.

Cardiogenic shock, cardiac arrest, acute respiratory failure, or a combination of such events, are all potential complications after cardiac surgery which lead to high mortality. Use of extracorporeal temporary cardio-circulatory and respiratory support for progressive clinical deterioration can facilitate bridging the patient to recovery or to more durable support. Over the last decade, extracorporeal membrane oxygenation (ECMO) has emerged as the preferred temporary artificial support system in such circumstances. Many factors have contributed to widespread ECMO use, including the relative ease of implantation, effectiveness, versatility, low cost relative to alternative devices, and potential for full, not just partial circulatory support. While there have been numerous publications detailing the short and midterm outcomes of ECMO support, specific reports about post-cardiotomy ECMO (PC-ECMO), are limited, single-center experiences. Etiology of cardiorespiratory failure leading to ECMO implantation, associated ECMO complications, and overall patient outcomes may be unique to the PC-ECMO population. Despite the rise in PC-ECMO use over the past decade, short-term survival has not improved. This report, therefore, aims to present a comprehensive overview of the literature with respect to the prevalence of ECMO use, patient characteristics, ECMO management, and in-hospital and early post-discharge patient outcomes for those treated for post-cardiotomy heart, lung, or heart-lung failure.

Structured review of post-cardiotomy extracorporeal membrane oxygenation: Part 2-pediatric patients.

Veno-arterial extracorporeal membrane oxygenation (ECMO) is established therapy for short-term circulatory support for children with life-treating cardiorespiratory dysfunction. In children with congenital heart disease (CHD), ECMO is commonly used to support patients with post-cardiotomy shock or complications including intractable arrhythmias, cardiac arrest, and acute respiratory failure. Cannulation configurations include central, when the right atrium and aorta are utilized in patients with recent sternotomy, or peripheral, when cannulation of the neck or femoral vessels are used in non-operative patients. ECMO can be used to support any form of cardiac disease, including univentricular palliated circulation. Although veno-arterial ECMO is commonly used to support children with CHD, veno-venous ECMO has been used in selected patients with hypoxemia or ventilatory failure in the presence of good cardiac function. ECMO use and outcomes in the CHD population are mainly informed by single-center studies and reports from collated registry data. Significant knowledge gaps remain, including optimal patient selection, timing of ECMO deployment, duration of support, anti-coagulation, complications, and the impact of these factors on short- and long-term outcomes. This report, therefore, aims to present a comprehensive overview of the available literature informing patient selection, ECMO management, and in-hospital and early post-discharge outcomes in pediatric patients treated with ECMO for post-cardiotomy cardiorespiratory failure.

In-hospital outcome of post-cardiotomy extracorporeal life support in adult patients: the 2007-2017 Maastricht experience.

OBJECTIVES: The use of post-cardiotomy extracorporeal life support (PC-ECLS) has increased worldwide over the past years but a concurrent decrease in survival to hospital discharge has also been observed. We analysed use and outcome of PC-ECLS at the Maastricht University Medical Center. DESIGN: A retrospective study of a single-centre PC-ECLS cohort. Patient characteristics and in-hospital outcomes were evaluated. SETTING: Patients who underwent PC-ECLS due to intra- or peri-operative cardiogenic shock or cardiac arrest were included. Descriptive statistics were analysed and frequency analysis and testing of group differences were performed. PARTICIPANTS: Eighty-six patients who received PC-ECLS between October 2007 and June 2017 were included. The mean age of the population was 65 years (range, 31-86 years), and 65% were men. MAIN OUTCOME MEASURES: Survival rates were calculated and PC-ECLS management data and complications were assessed. RESULTS: Pre-ECLS procedures were isolated coronary artery bypass grafting (CABG) (22%), isolated valve surgery (16%), thoracic aorta surgery (4%), a combination of CABG and valve surgery (21%) or other surgery (24%). PC-ECLS was achieved via central cannulation in 17%, peripheral cannulation in 65%, or by a combination in 17%. The median duration of PC-ECLS was 5.0 days (IQR, 6.0 days). Weaning was achieved in 49% of patients, and 37% survived to discharge. Post-operative bleeding (overall rate, 42%) showed a trend towards a reduced rate over more recent years. CONCLUSIONS: Our experience confirms an increased use of PC-ECLS during the last 10 years and shows that, by carefully addressing patient management and complications, survival rat e may be satisfactory, and improved outcome may be achieved in such a challenging ECLS setting.

Modalities and Effects of Left Ventricle Unloading on Extracorporeal Life support: a Review of the Current Literature.

INTRODUCTION/AIM: Veno-arterial extracorporeal membrane oxygenation (V-A ECMO) support is increasingly used in refractory cardiogenic shock and cardiac arrest, but is characterized by a rise in afterload of the left ventricle (LV) which may ultimately either further impair or delay cardiac contractility improvement. The aim of this study was to provide a comprehensive overview regarding the different LV venting techniques and results currently available in the literature. METHODS: A systematic literature search was performed in the PubMed database: 207 articles published between 1993 and 2016 were included. Papers dealing with pre-clinical studies, overlapping series, and association with other assist devices were excluded from the review, with 45 published papers finally selected. Heterogeneous indications for LV unloading were reported. The selected literature was divided into subgroups, according to the location or the performed procedure for LV venting. RESULTS: Case reports or case series accounted for 60% of the papers, while retrospective study represented 29% of them. Adult series were present in 67%, paediatric patients in 29%, and a mixed population in 4%. LV unloading was performed percutaneously in 84% of the cases. The most common locations of unloading was the left atrium (31%), followed by indirect unloading (intra-aortic balloon pump) (27%), trans-aortic (27%), LV (11%), and pulmonary artery (4%). Percutaneous trans-septal approach was reported in 22%. Finally, the unloading was conducted surgically in 16%,with open chest surgery in 71%, and minimally invasive surgery in 29% of surgical cases. CONCLUSION: Nowadays, only a few data are available about left heart unloading in V-A ECMO support. Despite the well-known controversy, IABP remains widely used in combination with V-A ECMO. Percutaneous approaches utilizing unloading devices is becoming an increasingly used option. However, further studies are required to establish the optimal LV unloading method.
