FVIII production by human lung microvascular endothelial cells
2006
While extrahepatic factor VIII (FVIII) synthesis suffices for hemostasis, the extrahepatic production sites are not well defined. We therefore investigated the ability of the human lungs to produce FVIII. Lungs from heart-beating donors who were declined for transplantation were perfused and ventilated in an isolated reperfusion model for 2 hours. A progressive accumulation of FVIII and von Willebrand factor (VWF) was recorded in the perfusion medium in 3 of 4 experiments. By contrast, factor V, fibrinogen, and immunoglobulin G (IgG) levels remained constant during the perfusion period, indicating that the accumulation of FVIII and VWF was not due to diffusion from the intercellular medium …
The disease-specific clinical trial network for primary ciliary dyskinesia: PCD-CTN
2022
Primary ciliary dyskinesia; Rare genetic disorder; Lung diseases Discinesia ciliar primaria; Trastorno genético raro; Enfermedades pulmonares Discinesia ciliar primària; Trastorn genètic rar; Malalties pulmonars Primary ciliary dyskinesia (PCD) is a rare genetic disorder characterised by impaired mucociliary clearance leading to irreversible lung damage. In contrast to other rare lung diseases like cystic fibrosis (CF), there are only few clinical trials and limited evidence-based treatments. Management is mainly based on expert opinions and treatment is challenging due to a wide range of clinical manifestations and disease severity. To improve clinical and translational research and facili…
Evaluation of gastric intramucosal pH during and after pediatric cardiac surgery.
1997
Objectives: In adult patients, intramucosal pH (pHi) has been advocated to detect postoperative complications. The purpose of our study was to evaluate this technique in pediatric patients during and after cardiac surgery. Methods: Thirty-five infants (age: 5 days to 15 years, median 1.8 years; and weight: 3.2‐32 kg, median 9.8 kg) were studied. pHi was measured before cardiopulmonary bypass (CPB), after 30 min of CPB, prior to weaning off CPB, at intensive care unit arrival, and 6, 12, 24, 48 and 72 h after surgery. Results: There were no complications related to the tonometer. A pathologically low pHiB 7.32 was found during surgery in less than 17%, at intensive care unit arrival in 83% a…
Pulmonary microvascular architecture in hereditary haemorrhagic telangiectasia
2017
A 24-year-old Caucasian man was admitted with a known hereditary haemorrhagic telangiectasia (HHT) and heterozygous mutation of factor V Leiden following episodes of cerebral infarctions in occipital lobes, cerebellum and brainstem. In his case history, the patient underwent several interventional embolisation of arteriovenous (AV) malformations in the middle and lower lobes (figure 1). However, those were not completely successful as the malformations were diffuse. We performed video-assisted thoracoscopic surgery with a resection of the middle lobe and a wedge resection of segment 10. Figure 1 CT scans depict the pulmonary arteriovenous malformations after re-embolisation in the middle lo…
Shedding some light on tricuspid intervention
2021
Background More than 1.6 million Americans have at least moderate to severe valvular tricuspid regurgitation, yet fewer than 8000 tricuspid valve operations are performed annually in the USA. The undertreatment for isolated tricuspid regurgitation might be related to the fact that in the past years no clear guidelines on 'how' and 'when' to treat tricuspid regurgitation were issued. Aims Sarris-Michopoulos and colleagues carried out a meta-analysis with the aim to investigate the role of tricuspid valve repair versus tricuspid valve replacement in patients with isolated tricuspid valve regurgitation. Material and methods Outcomes of patients with first-time surgery for isolated tricuspid va…
Patterns of Safety Incidents in a Neonatal Intensive Care Unit
2021
Introduction: Safety incidents preceding manifest adverse events are barely evaluated in neonatal intensive care units (NICUs). This study aimed at identifying frequency and patterns of safety incidents in our NICU.Methods: A 6-month prospective clinical study was performed from May to October 2019 in a German 10-bed level III NICU. A voluntary, anonymous reporting system was introduced, and all neonatal team members were invited to complete paper-based questionnaires following each particular safety incident. Safety incidents were defined as safety-related events that were considered by the reporting team member as a “threat to the patient's well-being” which “should ideally not occur agai…
The Lasting Influences of Early Food-Related Variety Experience: A Longitudinal Study of Vegetable Acceptance from 5 Months to 6 Years in Two Populat…
2016
International audience; Children's vegetable consumption falls below current recommendations, highlighting the need to identify strategies that can successfully promote better acceptance of vegetables. Recently, experimental studies have reported promising interventions that increase acceptance of vegetables. The first, offering infants a high variety of vegetables at weaning, increased acceptance of new foods, including vegetables. The second, offering an initially disliked vegetable at 8 subsequent meals markedly increased acceptance for that vegetable. So far, these effects have been shown to persist for at least several weeks. We now present follow-up data at 15 months, 3 and 6 years ob…
Peri-operative red blood cell transfusion in neonates and infants: NEonate and Children audiT of Anaesthesia pRactice IN Europe: A prospective Europe…
2022
BACKGROUND Little is known about current clinical practice concerning peri-operative red blood cell transfusion in neonates and small infants. Guidelines suggest transfusions based on haemoglobin thresholds ranging from 8.5 to 12���g���dl-1, distinguishing between children from birth to day 7 (week 1), from day 8 to day 14 (week 2) or from day 15 (���week 3) onwards. OBJECTIVE To observe peri-operative red blood cell transfusion practice according to guidelines in relation to patient outcome. DESIGN A multicentre observational study. SETTING The NEonate-Children sTudy of Anaesthesia pRactice IN Europe (NECTARINE) trial recruited patients up to 60 weeks' postmenstrual age undergoing anaesthe…
Survey of neonatal respiratory support use in very preterm infants in Italy
2012
Background: Respiratory support in very preterm infants is often a life-saving procedure and several techniques are available. There is lack of data on the current use of these techniques. Methods and aim: We analyzed a cohort of infants <30 weeks gestation or < 1501 g birth weight, enrolled in the Italian Neonatal Network in 2009 and 2010 (n = 8297, mean gestation = 29.3 weeks, mean birth weight = 1089 g) to ascertain the use of several techniques. We also conducted a questionnaire survey of all neonatal units adhering to the Italian Neonatal Network, inquiring about preferred methods of respiratory support. Results: Conventional ventilation was used in 53% of these infants, high frequency…
Unilateral neonatal cerebral infarction in full term infants
1997
AIMS—To determine the prevalence of unilateral neonatal cerebral infarction in infants born at 32 weeks gestation and above; to describe the clinical course, imaging results, and outcome of neonatal cerebral infarction; and to investigate possible aetiology. METHODS—Twelve cases of unilateral neonatal cerebral infarction were identified from neonatal unit records for the years 1987-93. Each case was matched with two controls. RESULTS—All cases of neonatal cerebral infarction occurred in full term infants. The prevalence was around 1 in 4000, and neonatal cerebral infarction was found in 12% of infants presenting with neonatal seizures. Cerebral ultrasound scans failed to demonstrate lesions…
