Analysis of nonsuicidal self-injury posts on Twitter: A quantitative and qualit...
Silva, Aline; Vedana, Kelly Graziani Giacchero; Santos, José Carlos Pereira dos; Pillon, Sandra; Ventura, Carla; Miasso, AdrianaRetrospective study, of mixed approach, with quantitative and qualitative approaches, with the objective of analyzing posts about non-suicidal self-harm on Twitter. The posts were collected through screen capture, transcribed and encoded. Quantitative data were analyzed using descriptive statistics, association tests and multiple logistic regression, with a significance level of 5%. Qualitative data were analyz...
Attitudes of Portuguese nursing undergraduate students toward suicidal behaviour
Vedana, Kelly; Santos, José Carlos Pereira dos; Zanetti, Ana; Miasso, Adriana; Ventura, Carla; Pillon, Sandra; Souza, Jacqueline; Silva, AlineBackground/Aims The attitudes toward suicidal behaviour and related factors are still not understood and may influence the quality of assistance. The attitudes of nursing students regarding suicide and associated factors was investigated in this study. Methods A cross-sectional study was carried out with 351 nursing students in a Portuguese higher education institution. Data were collected in 2017-2018, using a...
The meaning of suicidal behaviour from the perspective of senior nursing underg...
Vedana, Kelly Graziani Giacchero; Pereira, Camila Correa Matias; Santos, José Carlos Pereira dos; Ventura, Carla; Moraes, Sabrina; Miasso, AdrianaThe meaning ascribed to suicidal behaviours may influence the quality of the care provided to people at risk of suicide. Such a phenomenon has yet to be properly investigated amongst nursing undergraduate students, the aim of this study being to gain an understanding of the meanings of suicidal behaviour for a particular group of nurses. The study, which utilized grounded theory, was conducted in Brazil in 2016...
Estado nutricional em doentes oncológicos
Vila, Ana; Ventura, Carla; Barros, Diana; Ribeiro, Mafalda; Leite, Mariana; Fernandes, António; Pereira, Ana Maria Geraldes RodriguesO cancro, assumido como um problema de saúde pública, tem um impacto cada vez mais emergente nas sociedades atuais. A perda de peso e a desnutrição são complicações frequentes, com consequente aumento da morbilidade e mortalidade destes doentes. Segundo as estimativas da International Agency for Research on Câncer (IARC), em 2008 surgiram 12,7 milhões de novos casos de cancro em todo o Mundo, sendo responsável ...
Ocular injectable formulation assessment for oxidized dextranbased hydrogels
Maia, João; Ribeiro, Maximiano; Ventura, Carla; Carvalho, Rui A.; Correia, Ilídio J.; Gil, Maria H.Initiator-free injectable hydrogels are very interesting for drug and/or cell delivery applications, since they can be administered in a minimally invasive way, and avoid the use of potentially harmful chemical initiators. In the current work, oxidized dextran crosslinked with adipic acid dihydrazide hydrogels were further characterized and tuned to produce formulations, with the aim of producing an injectable ...

Flow dynamics of pulp fiber suspensions
Ventura, Carla; Garcia, Fernando; Ferreira, Paulo; Rasteiro, MariaThe transport between different equipment and unit operations plays an important role in pulp and paper mills because fiber suspensions differ from all other solid-liquid systems, due to the complex interactions between the different pulp and paper components. Poor understanding of the suspensions’ flow dynamics means the industrial equipment design is usually conservative and frequently oversized, thus contrib...
Modeling pulp fiber suspension rheology
Ventura, Carla; Blanco, Angeles; Negro, Carlos; Ferreira, Paulo; Garcia, Fernando; Rasteiro, MariaRheological properties of pulp suspensions play a very important role in the industry, mainly due to the consumption of energy for transporting pulp among the different parts of the paper mill. In this work, we determined the rheology of long- and short-fiber bleached kraft pulp suspensions by using a new rotational viscometer especially designed for their analysis. The experimental rheograms were adjusted to t...
