Local-scale factors matter for tree cover modelling inMediterranean drylands

Forests contribute directly to ecosystem structure and functioning, maintaining biodiversity, acting as a climate regulator and reducing desertification. To better manage forests, it is essential to have high-resolution forest models and appropriate spatial-explicit variables able to explain tree cover at different scales, including the management scale. Most tree cover models rely only on broad-scale variables...

Bacterial growth and recovery on hospital biometric devices: effect of two type...

Objectives: The aim of the study was to evaluate the presence of bacterial contamination on biometric identification devices in a public hospital; identify the species of bacteria implicated in the contamination and assess bacterial recovery after the use of 2 types of disinfectants: alcohol 70% and isopropyl alcohol chlorhexidine. Design: Before and after trial. Setting: Public hospital, tertiary referral cent...

Assessment of anesthetic gases in a central hospital

Introduction: Adverse health effects related with chronic exposure to waste anesthetic gases remain controversial. Strict threshold values are recommended to minimize possible health risks. The objective of our study was to measure the concentration of waste anesthetic gases in different hospital settings in an 11-year period. Materials and methods: Six-monthly assessment of nitrous oxide, sevoflurane, and desf...

Diagnosis, treatment, and work impact of iron deficiency anemia in a Portuguese...

Introduction: Little is known about iron deficiency anemia (IDA)'s treatment in Portugal. We aim to estimate the proportion of anemia, IDA, and iron deficiency without anemia; characterize the diagnostic procedures and prescription patterns; assess anemia's impact over work absenteeism, in a Local Health Unit. Material and methods: Cross-sectional study that evaluated complete blood counts, iron-containing pres...

Measuring and mapping the effectiveness of the European Air Quality Directive i...

To protect human health and the environment (namely ecosystems), international air quality protocols and guidelines, like the Gothenburg protocol (1999) and the 2001 EU Air Quality Directive (NECD), conveyed national emission ceilings for atmospheric pollutants (Directive 2001/81/EC), including the reduction of sulfur (S) and nitrogen (N) emissions by 2010. However, to what degree this expected reduction in emi...

Inspiratory muscle training is effective to reduce postoperative pulmonary comp...

Purpose: This study systematically review and meta-analyse the effectiveness of inspiratory muscle training (IMT) to reduce postoperative pulmonary complications (PPC) and length of hospital stay (LOS), both in the preoperative and/or postoperative periods of cardiac, pulmonary, and abdominal surgical patients. Sensitive analysis was performed to examine which patients benefit more from IMT according to methodo...

Using nitrogen concentration and isotopic composition in lichens to spatially a...

Reactive nitrogen (Nr) is an important driver of global change, causing alterations in ecosystem biodiversity and functionality. Environmental assessments require monitoring the emission and deposition of both the amount and types of Nr. This is especially important in heterogeneous landscapes, as different land-cover types emit particular forms of Nr to the atmosphere, which can impact ecosystems distinctively...

Permanent pacemaker implantation after aortic valve replacement: Long-term depe...

Introduction Conduction disturbances requiring permanent pacemaker (PM) implantation occur in 3-12% of patients after aortic valve replacement (AVR). Our aim was to assess long-term PM dependency and its predictors in these patients. Methods We conducted a retrospective study of all consecutive patients undergoing permanent PM implantation after AVR between January 2004 and December 2010. Absence of sinus rhyth...

Anomalous coronary origin: From suspicion to surgical revascularization

Congenital anomalies of the coronary arteries are uncommon and can present a diagnostic challenge. The authors present the case of a patient with recurrent chest pain during exertion admitted for acute coronary syndrome. Coronary angiography revealed no coronary lesions but showed that the right coronary artery originated from the anterolateral aortic wall, above the sinuses of Valsalva, leading to suspicion of...
