Serum Zn Levels in Dysphagic Patients Who Underwent Endoscopic Gastrostomy for ...

Background and aims: Dysphagic patients who underwent endoscopic gastrostomy (PEG) usually present protein-energy malnutrition, but little is known about micronutrient malnutrition. The aim of the present study was the evaluation of serum zinc in patients who underwent endoscopic gastrostomy and its relationship with serum proteins, whole blood zinc, and the nature of underlying disorder. Methods: From patients...

The impact of North Atlantic Oscillation on the atmospheric pollutant variabili...

The North Atlantic Oscillation (NAO) is an important large-scale atmospheric circulation that influences the European countries climate. This study evaluated NAO impact in air quality in Porto Metropolitan Area (PMA), Portugal, for the period 2002-2006. NAO, air pollutants and meteorological data were statistically analyzed. All data were obtained from PMA Weather Station, PMA Air Quality Stations and NOAA anal...

Pulmonary hypertension in Portugal: first data from a nationwide registry

INTRODUCTION: Pulmonary arterial hypertension (PAH) is a rare disease that must be managed in specialized centers; therefore, the availability of epidemiological national data is critical. METHODS: We conducted a prospective, observational, and multicenter registry with a joint collaboration from five centers from Portugal and included adult incident patients with PAH or chronic thromboembolic pulmonary hyperte...

Clinical experience in invasive fungal infections

Lung infections caused by invasive filamentous fungi are very rare conditions in AIDS, but must be considered in patients with profound immune suppression especially in the presence of additional risk factors, such as hematologic malignancies, corticosteroid therapy, neutropenia, and chemotherapy. The authors report a case of dual lung infection caused by Aspergillus and Mucor, which occurred in a 34-year-old A...

Tenogenic potential of human stem cells from the amniotic fluid and adipose tissue

Tendons are highly prone to injury and the intrinsic hypocellularity and hypovascularity make their natural healing extremely slow and inefficient when severed damaged. Surgical repair with grafts is common but unsuccessful in a long term basis. The development of tissue engineering strategies based on stem cells explores a natural endogenous system of regeneration with potential for tendon application. We prop...
