One-year variation in quantity and properties of microplastics in mussels (Myti...
Botelho, M. J.; Vale, C.; Marques, F.; Moreirinha, C.; Costa, S. T.; Guilhermino, L.; Joaquim, S.; Matias, D.; Candeias, M.; Rudnitskaya, A.As filter feeders, marine bivalves inhabiting estuarine and coastal areas are directly exposed to microplastics (MPs) in water. To assess whether MPs number, and their shape, size, colour, and polymer type present in mussels (Mytilus galloprovincialis) and cockles (Cerastoderma edule) varied over one year, bivalves were collected over the year of 2019 in the lower part of the coastal Aveiro lagoon, Portugal. Af...
BODY MASS INDEX AND BLOOD PRESSURE IN FIGUEIRA DA FOZ PEDIATRIC POPULATION - A ...
Paz, G.; Vale, C.; Teles, E.; Teixeira, C.; Ribeiro, M.; Martins, I.; Viegas, A.; Pereira, T.; Rosa, M.; Fernandes, F.Introduction and Objectives: Increasing number of studies show an association between overweight and obesity with arterial hypertension in childhood. The aim of this study was to assess body mass index (BMI) and high blood pressure (HBP) and its association in children and adolescents.Methods: Observational, cross-sectional and analytical study. Data was collected from the medical records of patients between 5 ...
The effect of chloride ions and organic matter on the photodegradation of aceta...
Pinto, M. I.; Salgado, Ricardo; Laia, C.A.T.; Cooper, William J.; Sontag, J.; Burrows, Hugh D.; Branco, L.; Vale, C.; Noronha, J. P.The photodegradation kinetics of the neonicotinoid insecticide acetamiprid (ACT) was investigated under different conditions of pH, salinity and dissolved organic matter (DOM). Photodegradation of ACT in saline and freshwaters followed pseudo-first-order kinetics. Varying pH from 5 to 9 did not significantly affect the photodegradation rate constants (kp) of ACT. Addition of chloride ions increased significantl...

Effect of pH and dissolved organic matter on the photochemical fate of acetamiprid
Pinto, M.I.; Salgado, Ricardo; Laia, C. A. T.; Branco, L.; Vale, C.; Cooper, William J.; Burrows, Hugh D.; Noronha, J. P.In this study the effect of pH and dissolved organic matter (DOM) on the photodegradation rate of acetamiprid (ACT) was studied. Observed photodegradation rate constants in the range of 0.0010 – 0.0026 h-1 and 24 – 36 h-1 were obtained using a solar simulator (290-800 nm) and a medium pressure mercury (MP Hg) lamp, respectively. In both experiments an increase in pH from 5 to 9 did not significantly change the ...
Astigmatism management in cataract surgery with Precizon(®) toric intraocular l...
Vale, C.; Menezes, C.; Firmino-Machado, J.; Rodrigues, P.; Lume, M.; Tenedório, P.; Menéres, P.; Brochado, M.PURPOSE: The purpose of this study was to evaluate the visual and refractive outcomes and rotational stability of the new aspheric Precizon(®) toric intraocular lens (IOL) for the correction of corneal astigmatism in cataract surgery. SETTING: Department of Ophthalmology, Hospital Geral de Santo António - Centro Hospitalar do Porto, EPE and Hospital de Pedro Hispano, Matosinhos, Portugal. DESIGN: This was a pro...
Purtscher-Like Retinopathy
Massa, R.; Vale, C.; Macedo, M.; Furtado, M.; Gomes, M.; Lume, M.; Meireles, A.Purtscher-like retinopathy is associated with retinal hemorrhages and ischaemia probably due to the complement-mediated leukoembolization. It is a rare and severe angiopathy found in conditions such as acute pancreatitis. Case. We present a case of a 53-year-old man who presented with a Purtscher-like retinopathy associated with the development of acute pancreatitis in the context of a Klatskin tumour (a hilar ...

Loureiro, I.F.; Rodrigues, Matilde; Vale, C.; Azevedo, R.Portugal is undergoing an economic crisis affecting the European Union since 2007. The financial unsustainability of Portugal required foreign aid and consequently austerity and structural measures have been implemented. These measures are causing negative impacts on the economy income and living conditions of the population of Portugal. Studies in this field can stimulate new challenges in Occupational Safety ...
