Práticas para a gestão de recursos hídricos em bacias hidrográficas com históri...
Nunes, João; Parente, Joana; Benali, Akli; Nitzsche, N.; Prats, Sergio; Sá, Ana; Brito, Carlos; Dias, LuisOs incêndios rurais são um fenómeno recorrente em Portugal. Muitas vezes as cinzas produzidas por estes incêndios atingem as massas de água utilizadas para o abastecimento público, comprometendo a sua qualidade. Num exemplo recente, as cinzas resultantes dos incêndios de 2017 levaram à interrupção do abastecimento de água a algumas localidades, e à implementação de programas de monitorização adicional em outras...
Assessing post-fire water quality changes in reservoirs: Insights from a large ...
Nitzsche, Niels; Nunes, João Pedro; Parente, JoanaWildfires in the Mediterranean basin, especially in Portugal, have increased in extent and frequency over the last few years. One of the impacts of wildfires on humans and ecosystems is on the water quality of surface waters. Ashes and increased erosion rates might, for example, change oxygen levels and elevate the influx of sediments, nutrients, or other water quality-related components like metals and polycyc...
Spontaneous Ileopsoas Hematoma: A Rare and Lethal Complication of Liver Cirrhosis
Parente, Joana; Siopa, LuísSpontaneous ileopsoas hematoma is a rare and potentially lethal complication of liver cirrhosis, with exceptional mention in medical literature. In this article we present a clinical case diagnosed in a patient with alcoholic liver cirrhosis.; O hematoma espontâneo do ileopsoas é uma complicação rara e potencialmente fatal da cirrose hepática, excepcionalmente mencionada na literatura. Descrevemos neste artigo ...
Quantitative Assessment of the Relationship between Land Use/Land Cover Changes...
Parente, Joana; Tonini, Marj; Stamou, Zoi; Koutsias, Nikos; Pereira, MárioWildfires are key drivers of land use/land cover (LULC) dynamics by burning vegetation and affecting human infrastructure. On the contrary, LULC changes (LULCCs) may affect the fire regime by influencing vegetation type, burnable areas, fuel loads and continuity. This study investigates the relationship between LULCC and wildfires. We developed a methodology based on different indicators, which allowed us to qu...
Testing simple approaches to map sediment mobilisation hotspots after wildfires
Parente, Joana; Nunes, João Pedro; Baartman, Jantiene; Föllmi, DanteBackground. The models currently used to predict post-fire soil erosion risks are limited by high data demands and long computation times. An alternative is to map the potential hydrological and sediment connectivity using indices to express the general properties of the burnt landscape. Aims. In this study, we aimed to answer the question: Do these tools identify post-fire sediment mobilisation hotspots? Metho...
Why do we Discontinue Biologic Agents? A Retrospective Study of 11 Years
Gil, Francisco; Rato, Margarida; Monteiro, Ana; Parente, Joana; Martins, César; Aranha, João; Silva, Maria JoãoIntroduction: Biologic agents acquired a growing relevance in dermatology, however, adverse events (AE) and reasons to discontinue therapy are not completely known. The objective of this study is to analyse the reasons behind the discontinuation of biologics and characterize the AE in this population of patients. Material and Methods: Descriptive observational study, including patients over 18-years-old under t...
(3S,4R)-3,4-Dihydroxy-N-alkyl-l-homoprolines: synthesis and computational mecha...
Freitas, David S.; Sousa, Cristina E. A.; Parente, Joana; Drogalim, Artem; Fortes, A. Gil; Cerqueira, Nuno M. F. S. A.; Rodríguez-Borges, José E.This is the first synthetic report of (3S,4R)-dihydroxy-N-alkyl-l-homoprolines described so far. 2,4-O-Benzylidene-d-erythrose was obtained from d-glucose with an improved yield, and then transformed into the title (3S,4R)-dihydroxy-N-alkyl-l-homoprolines, in a two-step strategy, with excellent overall yields. Hydrogenolysis of the benzyl group led to the NH congener. The synthesis of final products from 1,4-la...
Defining Extreme Wildfire Events: Difficulties, Challenges, and Impacts
Tedim, Fantina; Leone, Vittorio; Amraoui, Malik; Bouillon, Christophe; Coughlan, Michael; Delogu, Giuseppe; Fernandes, Paulo; Ferreira, CarmenEvery year worldwide some extraordinary wildfires occur, overwhelming suppression capabilities, causing substantial damages, and often resulting in fatalities. Given their increasing frequency, there is a debate about how to address these wildfires with significant social impacts, but there is no agreement upon terminology to describe them. The concept of extreme wildfire event (EWE) has emerged to bring some c...

Prevalence of risky alcohol consumption in the elderly: a study from a primary ...
Martins, Albino; Parente, Joana; Araújo, Joana; Menezes, Maria JoséIntroduction: Alcohol consumption is associated with risks and benefits depending on the quantity ingested. It is helpful to understand patterns of alcohol consumption in a population in order to decrease risk. The elderly represent a group of special interest, currently under-studied in this area. Family physicians can play a role in the evaluation and prevention of risky alcohol consumption in the elderly. Ob...
