Minimally invasive extracorporeal circulation resuscitation in hypothermic cardiac arrest.

Current guidelines for the treatment of hypothermic cardiocirculatory arrest recommend extracorporeal life support and rewarming, using cardiopulmonary bypass or extracorporeal membrane oxygenation circuits. Both have design-related shortcomings which may result in prolonged reperfusion time or insufficient oxygen delivery to vital organs. This article describes clear advantages of minimally invasive extracorporeal circulation systems during emergency extracorporeal life support in hypothermic arrest. The technique of minimally invasive extracorporeal circulation for reperfusion and rewarming is represented by the case of a 59-year-old patient in hypothermic cardiocirculatory arrest at 25.3°C core temperature, with multiple trauma. With femoro-femoral cannulation performed under sonographic and echocardiographic guidance, extracorporeal life support was initiated using a minimally invasive extracorporeal circulation system. Perfusing rhythm was restored at 28°C. During rewarming on the mobile circuit, trauma surveys were completed and the treatment initiated. Normothermic weaning was successful on the first attempt, trauma surgery was completed and the patient survived neurologically intact. For extracorporeal resuscitation from hypothermic arrest, minimally invasive extracorporeal circulation offers all the advantages of conventional cardiopulmonary bypass and extracorporeal membrane oxygenation systems without their shortcomings.

Anticoagulation Management Practices and Outcomes in Elderly Patients with Acute Venous Thromboembolism: A Clinical Research Study.

Whether anticoagulation management practices are associated with improved outcomes in elderly patients with acute venous thromboembolism (VTE) is uncertain. Thus, we aimed to examine whether practices recommended by the American College of Chest Physicians guidelines are associated with outcomes in elderly patients with VTE. We studied 991 patients aged ≥65 years with acute VTE in a Swiss prospective multicenter cohort study and assessed the adherence to four management practices: parenteral anticoagulation ≥5 days, INR ≥2.0 for ≥24 hours before stopping parenteral anticoagulation, early start with vitamin K antagonists (VKA) ≤24 hours of VTE diagnosis, and the use of low-molecular-weight heparin (LMWH) or fondaparinux. The outcomes were all-cause mortality, VTE recurrence, and major bleeding at 6 months, and the length of hospital stay (LOS). We used Cox regression and lognormal survival models, adjusting for patient characteristics. Overall, 9% of patients died, 3% had VTE recurrence, and 7% major bleeding. Early start with VKA was associated with a lower risk of major bleeding (adjusted hazard ratio 0.37, 95% CI 0.20-0.71). Early start with VKA (adjusted time ratio [TR] 0.77, 95% CI 0.69-0.86) and use of LMWH/fondaparinux (adjusted TR 0.87, 95% CI 0.78-0.97) were associated with a shorter LOS. An INR ≥2.0 for ≥24 hours before stopping parenteral anticoagulants was associated with a longer LOS (adjusted TR 1.2, 95% CI 1.08-1.33). In elderly patients with VTE, the adherence to recommended anticoagulation management practices showed mixed results. In conclusion, only early start with VKA and use of parenteral LMWH/fondaparinux were associated with better outcomes.

Association between thyroid dysfunction and venous thromboembolism in the elderly: a prospective cohort study.

BACKGROUND Venous thromboembolism (VTE) and subclinical thyroid dysfunction (SCTD) are both common in elderly patients. SCTD has been related to a hypercoagulable state and increased thromboembolic risk. However, prospective data on the relationship between SCTD and VTE are lacking. OBJECTIVES To investigate the relationship between SCTD and recurrent VTE (rVTE), all-cause mortality, and thrombophilic biomarkers. PATIENTS Elderly participants with VTE. METHODS In a prospective multicenter cohort, thyroid hormones and thrombophilic biomarkers were measured 1 year after acute VTE, as both may be influenced by acute thrombosis. We defined subclinical hypothyroidism (SHypo) as elevated thyroid stimulating hormone levels (TSH=4.50-19.99 mIU/l), and subclinical hyperthyroidism (SHyper) as TSH<0.45, both with normal free thyroxine levels. Outcomes were incidence of rVTE and overall mortality during follow-up starting after the 1-year blood sampling. RESULTS Of 561 participants (58% with anticoagulation), 6% had SHypo and 5% SHyper. After 20.8 months of mean follow-up, 9% developed rVTE and 10% died. rVTE incidence rate was 7.2 (95% confidence interval:2.7-19.2) per 100 patient-years in SHypo, 0.0 (0.0-7.6) in SHyper and 5.9 (4.4-7.8) in euthyroid participants. In multivariate analyses, the sub-hazard ratio [SHR] for rVTE was 0.00 (0.00-0.58) in SHyper and 1.50 (0.52-4.34) in SHypo compared to euthyroids, without increased thrombophilic biomarkers. SHyper (HR 0.80,0.23-2.81) and SHypo (HR 0.99,0.30-3.29) were not associated with mortality. CONCLUSION In elderly patients, SHyper may be associated with lower rVTE risks. SHypo showed a non-statistically significant pattern of an association with rVTE, without increased mortality or differences in thrombophilic biomarkers. This article is protected by copyright.

Quality of Life in Swiss Paediatric Inflammatory Bowel Disease Patients: Do Patients and Their Parents Experience Disease in the Same Way?

BACKGROUND AND AIMS Inflammatory bowel diseases (IBDs) may impair quality of life (QoL) in paediatric patients. We aimed to evaluate in a nationwide cohort whether patients experience QoL in a different way when compared with their parents. METHODS Sociodemographic and psychosocial characteristics were prospectively acquired from paediatric patients and their parents included in the Swiss IBD Cohort Study. Disease activity was evaluated by the Paediatric Crohn's Disease Activity Index (PCDAI) and the Paediatric Ulcerative Colitis Activity Index (PUCAI). We assessed QoL using the KIDSCREEN questionnaire. The QoL domains were analysed and compared between children and parents according to type of disease, parents' age, origin, education and marital status. RESULTS We included 110 children and parents (59 Crohn's disease [CD], 45 ulcerative colitis [UC], 6 IBD unclassified [IBDU]). There was no significant difference in QoL between CD and UC/IBDU, whether the disease was active or in remission. Parents perceived overall QoL, as well as 'mood', 'family' and 'friends' domains, lower than the children themselves, independently of their place of birth and education. However, better concordance was found on 'school performance' and 'physical activity' domains. Marital status and age of parents significantly influenced the evaluation of QoL. Mothers and fathers being married or cohabiting perceived significantly lower mood, family and friends domains than their children, whereas mothers living alone had a lower perception of the friends domain; fathers living alone had a lower perception of family and mood subscores. CONCLUSION Parents of Swiss paediatric IBD patients significantly underestimate overall QoL and domains of QoL of their children independently of origin and education.

The Character of Christian-Muslim Encounter: Essays in Honour of David Thomas

The Character of Christian-Muslim Encounter is a Festschrift in honour of David Thomas, Professor of Christianity and Islam, and Nadir Dinshaw Professor of Inter Religious Relations, at the University of Birmingham, UK. The Editors have put together a collection of over 30 contributions from colleagues of Professor Thomas that commences with a biographical sketch and representative tribute provided by a former doctoral student, and comprises a series of wide-ranging academic papers arranged to broadly reflect three dimensions of David Thomas’ academic and professional work – studies in and of Islam; Christian-Muslim relations; the Church and interreligious engagement. These are set in the context of a focussed theme – the character of Christian-Muslim encounters – and cast within a broad chronological framework.
