Vesicoperineal Fistula: A Rare Rectal Cancer Treatment Complication
Moreira, Luísa; Margarida, André; Vasconcelos, Marta; Garção, Nunes; Luz, CarlosA vesicoperineal fistula is an uncommon entity, described as an aberrant tract between the bladder lumen and the cutaneous surface of the perineum. We present the case of a 78-year-old male who underwent abdominoperineal resection and chemoradiotherapy for the treatment of non-metastatic, locally advanced rectal cancer. Five years later, he developed a pelvic floor hernia and underwent perineal mesh repair. A f...
Lignin from grape stalks: nanoparticle production through sonication
Cassoni, Ana C.; Bourbon, Ana Isabel Juncá Sottomayor Lisboa; Vasconcelos, Marta; Pintado, ManuelaLignin nanoparticles represent an emerging class of sustainable nanomaterials that can improve the valorisation of this abundant biopolymer through new applications [1 ]. This study focused on optimizing the production of lignin nanoparticles through sonication, using minimal amount of chemicals possible, while achieving small particle size and maintaining colloidal stability.
Mass tourism, cultural heritage, and traditional values within citizen lifestyl...
Vieira, Eduarda; Pelaez, Ana; Rosa, Inês; Lemos, Teresa; Bordalo, Rui; Vasconcelos, Marta; Moreira, PatríciaPorto has a rich urban mesh and unique cultural identity, whose preservation has been the basis of its historic centre classification as a World Heritage Site by UNESCO (1996). The increase in demand of Porto as a tourism destination since 2015 was simultaneously favoured by the opening of Porto’s airport new terminal that greatly powered low-cost companies and the licensing for the rehabilitation of houses for...
Novel polymeric nanoparticles as nanofertilisers for alkaline iron‐deficient co...
Pinho, Simão; Santos, Carla; Moniz, Tânia; Granja, Andreia; Sarraguça, Mafalda; Reis, Salette; Rangel, Maria; Vasconcelos, MartaBackground and aims Iron deficiency chlorosis (IDC) is a nutritional disorder impacting plants and is prevalent in calcareous alkaline soils, correspond- ing to 30% of the world’s arable land. IDC compro- mises iron uptake in crops such as soybean (Glycine max). To improve the effect of iron fertilisers, we sought to develop a nanotechnology-based interven- tion using polymeric nanoparticles (NPs) loaded with F...
Characteristics of lower-limb peripheral arterial disease in women
Vasconcelos, Marta; Costa, Patrício; Alonso, Rita; Ferreira, JoanaINTRODUCTION: Peripheral Arterial Disease (PAD) affects more than 200 million people. Its estimated prevalence in women ranges from 3% to 29%. Asymptomatic PAD is more common in women than in men. However, when symptomatic, females present a more complex disease, severe critical limb-threatening ischemia (CLTI), and worse outcomes. This study aims to characterize PAD in hospitalized women, evaluating risk facto...
Impact of a daily legume-based meal on blood and anthropometric parameters in a...
Ferreira, Helena; Vasconcelos, Marta; Gil, Ana M.; Silveira, Joana; Alves, Paulo; Martins, Sandra; Assunção, Marco; Guimarães, João TiagoThis pilot study aimed to assess the impact of substituting a traditional lunch for a vegetarian legume-based meal on blood and anthropometric parameters in a group of omnivorous adults. A one-group comparison, quasi-experimental dietary intervention was designed. A vegetarian legume-based meal was offered for 8 consecutive weeks (weekdays) to non-vegetarian individuals (n = 26), (28 years [P25 = 20.0, P75 = 35...
Predicting iron deficiency and oxidative stress in glycine max through Fourier ...
Santos, Carla S.; Sousa, Clara; Bagheri, Maryam; Pinho, Simão; Vasconcelos, MartaAims: The excessive use of fertilizers is a problem in current agricultural systems, and sustainable farming practices, including precision agriculture, demand the use of new technologies to manage plant stress at an early stage. To sustainably manage iron (Fe) fertilization in agricultural fields, it is urgent to develop early detection methods for Fe deficiency, and linked oxidative stress, in plant leaves. H...
Combined effect of elevated CO2 and Fe deficiency on common bean metabolism and...
Deuchande, Teresa; Vasconcelos, MartaAims: Elevated atmospheric CO2 (eCO2) and restricted iron (Fe) supply are known to impact plant growth and nutritional quality of food crops. However, studies aimed at understanding how eCO2 will interact with Fe deficiency are scarce. Changes in the nutritional status of the common bean (Phaseolus vulgaris L.) may significantly impact the nutritional status of populations that rely heavily on this crop. Method...
Exploring demand: challenges and opportunities for free-from and organic foods ...
Lemos, Teresa; Vasconcelos, Marta; Sousa, Sérgio; Pinho, Simão; Gomes, Ana M.; Pinto, ElisabeteThe rising prevalence of food intolerances and increased health and environmental consciousness has driven the demand for free-from (FF) and organic products. This study aims to analyze consumer needs, motivations, and challenges related to these products in Portugal through an online survey with 2268 eligible responses, with a median age of the participants of 41 years. The sample was predominantly female (76....
Impact of a legumes diet on the human gut microbiome articulated with fecal and...
Ferreira, Helena; Duarte, Daniela; Carneiro, Tatiana J.; Costa, Célia; Barbosa, Joana C.; Rodrigues, João E.; Alves, Paulo; Vasconcelos, MartaBackground & aims: Legumes intake is known to be associated with several health benefits the origins of which is still a matter of debate. This paper addresses a pilot small cohort to probe for metabolic aspects of the interplay between legumes intake, human metabolism and gut microbiota. Methods: Untargeted nuclear magnetic resonance (NMR) metabolomics of blood plasma and fecal extracts was carried out, in tan...
