We present the case of a 52 year-old obese (BMI = 46.2 kg/m(2)) man with severe obstructive sleep apnea (RDI of 60). Before CPAP treatment was applied, the patient was diagnosed with complete respiratory failure and polycythemia. During effective autoCPAP treatment (after 10 days AHI was 5.5 at 10 mbar pressure) we observed normalization of arterial blood gases (PaCO(2) of borderline value). Af...

AIM To describe normal values of the cerebral tissue oxygenation index (TOI) in premature infants. METHODS TOI was measured by spatially resolved spectroscopy in preterm infants on the first 3 days of life. Infants with an abnormal cranial ultrasound were excluded. Other simultaneously measured variables were PaO(2), PaCO(2), pH, mean arterial blood pressure, heart rate, haemoglobin, glycaemi...

STUDY OBJECTIVE To evaluate whether the discontinuation of furosemide treatment resulted in a decrease in PaCO(2) and an increase in daytime and nocturnal oxygenation. BACKGROUND Furosemide is widely prescribed in patients with COPD for the treatment of peripheral edema. It is known that furosemide causes a metabolic alkalosis. A diminished chemoreceptor stimulation may cause a decreased alve...

It’s often crucial to choose a good architecture to succeed in a project. This is even more so when it comes to modeling Cooperative Information Systems (CoIS). Whenever we deal with cooperation, the information system of an organization doesn’t depend neither on definite nor exhaustive conceptual choices. This makes it necessary to define methods and models that can fulfill the conceptual need...

Understanding a user’s motivations provides valuable information beyond the ability to recommend items. Quite often this can be accomplished by perusing both ratings and review texts, since it is the latter where the reasoning for specific preferences is explicitly expressed. Unfortunately matrix factorization approaches to recommendation result in large, complex models that are difficult to in...

The effect of carbon dioxide on the neuromuscular blocking effect of the non-depolarizing muscle relaxants tubocurarine and gallamine has been known for some time. Kalow (1954) noted that the action of tubocurarine on an isolated muscle preparation was increased by lowering the pH. Payne (1958) found that in the anaesthetized cat the activity of tubocurarine was increased with a reduction of pH...

This paper presents PACO-T, a common sense-aided computational tool that helps teachers on planning culturally contextualized learning activities supported by common sense knowledge. The tool is based on the framework PACO, a seven-step framework for planning learning activities that concerns pedagogical issues, for an effective learning. It implements the framework seven steps and makes availa...
