BACKGROUND: Studying ventilation and intrathoracic pressure (ITP) induced by chest compressions (CC) during Cardio Pulmonary Resuscitation is challenging and important aspects such as airway closure have been mostly ignored. We hypothesized that Thiel Embalmed Cadavers could constitute an appropriate model. METHODS: We assessed respiratory mechanics and ITP during CC in 11 cadavers, and we compared it to measurements obtained in 9 out-of-hospital cardiac arrest patients and to predicted values from a bench model...

PURPOSE: We aimed to investigate the factors that are associated with increased cardiac troponin I (cTnI) leakage in the acute pulmonary embolism (PTE) setting and their alignment with patient outcome. METHODS: Adult patients with a diagnosis of PTE were enrolled in this prospective cohort study. The primary endpoint of interest was major adverse cardio-pulmonary events (MACPE), defined as the composite of in-hospital all-cause mortality, need for thrombolysis and mechanical ventilation and surgical embolectomy during index hospitalization...

Background -Based on laboratory cardiopulmonary resuscitation (CPR) investigations and limited adult data demonstrating that survival depends on attaining adequate arterial diastolic blood pressure (DBP) during CPR, American Heart Association recommends using BP to guide pediatric CPR. However, evidence-based BP targets during pediatric CPR remain an important knowledge gap for CPR guidelines. Methods -All children ≥37 weeks gestation and <19 years old in Collaborative Pediatric Critical Care Research Network intensive care units with chest compressions for ≥1 minute and invasive arterial blood pressure monitoring prior to and during CPR between July 1, 2013 and June 31, 2016 were included...

BACKGROUND: The ongoing supply-demand gap with respect to donor kidneys for transplantation necessitates the increased use of higher kidney donor profile index and/or donation after circulatory death (DCD) kidneys. Machine perfusion (MP) preservation has become increasingly popular as a means to preserve such organs. Human data regarding normothermic kidney MP (NMP) is in its infancy, and such a system has not been established in the Australasian clinical setting. METHODS: Modified cardio-pulmonary bypass technology was utilized to develop a viable NMP kidney perfusion system using a porcine DCD model...

Lung transplantation remains the ultimate treatment option for selected patients with end-stage (cardio) pulmonary disease. Given the current organ shortage, it is without any doubt that careful selection of potential transplant candidates is essential as this may greatly influence survival after the procedure. In this paper, we will review the current guidelines for referral and listing of lung transplant candidates in general, and in more depth for the specific underlying diseases. Needless to state that these are not absolute guidelines, and that decisions depend upon center's activity, waiting list, etc...

The incidence of Cardiac (Cardio-Pulmonary) Arrest (CA) in the Catheterization Laboratory is not common. However, not only does it happen occasionally but its frequency tends to increase due to the increase in the overall number and complexity of interventions performed by interventional cardiologists. Therefore, certified knowledge and application of the ALS (Advanced Life Support) protocols by trained Catheterization Laboratory staff is imperative in many countries, by local Hospital standards and also by Law...

BACKGROUND: N-terminal pro-brain-type natriuretic peptide (NT-proBNP) is currently used as a surrogate marker for disease severity in pulmonary hypertension (PH). However, NT-proBNP tends to have a high variability and may insufficiently correlate with hemodynamics and exercise capacity. METHODS: To investigate the association of NT-proBNP with hemodynamics and cardio-pulmonary exercise testing (CPET) in 84 therapy-naive patients with precapillary PH. RESULTS: NT-proBNP levels were significantly correlated with hemodynamics and CPET parameters except for cardiac index, diffusion capacity, PaO2 at peak exercise, and peak minute ventilation...

BACKGROUND: The neurological prognosis is poor for patients suffering from out-of-hospital cardiac arrest (OHCA), in the absence of bystander cardio pulmonary resuscitation (CPR), and showing asystole as the initial waveform. However, such patients have the potential of resuming social activity if cerebral tissue oxygen saturation can be preserved. CASE PRESENTATION: We recently encountered a 60-year-old man who had suffered an OHCA in the absence of bystander CPR, and who successfully resumed complete social activity despite initial asystole and requiring at least 75min of chest compressions before return of spontaneous circulation (ROSC)...

Cardiopulmonary resuscitation is a lifesaving technique for victims of sudden cardiac arrest. Despite advances in resuscitation science, basic life support remains a critical factor in determining outcomes. The American Heart Association recommendations for adult basic life support incorporate the most recently published evidence and serve as the basis for education and training for laypeople and healthcare providers who perform cardiopulmonary resuscitation.

HAPE susceptible (HAPE-S, had HAPE episode in past) subjects may have subclinical cardio-pulmonary dysfunction. We compared the results of pulmonary function tests in 25 healthy HAPE-S non-mountaineers and 19 matched HAPE resistant (HAPE-R, no HAPE episode in past). Acute normobaric hypoxia (FIo2 0.12) was administered at sea level to confirm hypoxia intolerance in HAPE-S. Unlike HAPE-R, HAPE-S subjects had elevated baseline and post-hypoxia systolic pulmonary arterial pressures (20.9 ± 3 vs 27.3 ± 5 mm Hg during normoxia and 26...

PURPOSE: Current evidence indicates that the common AMPD1 gene variant is associated with improved survival in patients with advanced heart failure. Whilst adenosine has been recognized to mediate the cardioprotective effect of C34T AMPD1, the precise pathophysiologic mechanism involved remains undefined to date. To address this issue, we used cardio-pulmonary exercise testing data (CPX) from subjects with myoadenylate deaminase (MAD) defects. METHODS: From 2009 to 2013, all the patients referred in our laboratory to perform a metabolic exercise testing, i...

A 69-year-old woman was admitted to the emergency unit due to respiratory distress. Initially the blood pressure was normal. However, it decreased concomitant with low saturation (70%), and it was decided to intubate her due to hypoxia. During intubation, she developed in-hospital cardiac arrest with pulseless electric activity as initial rhythm. Cardio pulmonary resuscitation was initiated, but sufficient spontaneous circulation was not obtained. We successfully initiated extracorporeal life support, and the patient survived with a good outcome...

Basal cell carcinoma (BCC) is the most common skin malignancy in humans. Giant BCC is a rarer entity that is characterised by aggressive biological behaviour. Intracranial invasion by a BCC on the scalp is extremely rare. The gold standard treatment of BCCs is represented by surgical excision with a wide variety of reconstructive techniques. In this paper, we describe the largest series to date of recurrent BCCs with intracranial extension involving the dura mater. We report recurrent giant BCC of the scalp with dura mater invasion in 7 patients...
