The relevance of support devices for kangaroo mother care in neonatology units:...
Correia, Carolina; Nunes, Célia; Cordeiro, Manuel; Bica, IsabelIntroduction: Kangaroo Mother Care (KMC) is one of the most effective strategies for caring for newborn and their parents, based on the philosophy of Family-Centered Care (FCC). Current literature points out that the safety of the newborn, the lack of resources in Neonatology services, such as protective devices during KMC, are barriers to the efficient implementation of the kangaroo method. Objective: To ident...
Addressing the algebraic structure of a linear mixed model with balanced design...
Dias, Cristina; Brites, Nuno M.; Nunes, Célia; Mexia, João Tiago; Santos, CarlaLinear mixed models provide a general and versatile approach for analyzing data collected in experiments, suitable for modeling repeated, longitudinal, or clustered observations. Important results for estimation can be obtained when subclasses of these mixed models are considered, based on some characteristics of their algebraic structure. The class of the models with commutative orthogonal block structure, for...
Interference of difficulties in mindful acceptance and emotional intelligence, ...
Magalhães, Teresa; Teixeira, R.J.; Vitória, Paulo; Nunes, Célia; Meireles, Ana; Marques, Mariana Vaz; Carvalho, Frederica; Brandão, TâniaBackground: Mental health conditions, that exhibit high prevalence within the Portuguese population, can impact individuals' functioning and adversely affect their performance across various aspects of life. Thus, it is crucial to enhance our comprehension of the psychological processes that contribute to the onset or persistence of mental health problems. Recent studies have indicated that mindfulness, emotion...
Operations with Iso-structured models with commutative orthogonal block structu...
Dias, Cristina; Nunes, Célia; Mexia, João Tiago; Santos, CarlaAn approach to models based on an algebraic context allows interesting and useful statistical results to be derived or at least better understood. In the approach to models with commutative orthogonal block structure via algebraic structure it is possible to show that the orthogonal projection matrix in the space spanned by the mean vector commuting with the covariance matrix guarantees least squares estimators...
RCO-5 Relação entre as condições dos estágios clínicos e o desempenho académico...
Ganicho, José; Neto, Isabel; Nunes, CéliaIntrodução e Objectivos: Embora se considere que a aprendizagem em meio clínico é crucial para a aquisição de competências enquanto futuros médicos, o nosso conhecimento sobre o processo de aprendizagem é limitado (1,2). Efetivamente, para além de uma incompleta compreensão sobre as variáveis que influenciam o processo educativo, existe uma enorme variação entre os estudantes e a sua experiência (3), pelo que a...
Body composition and grip strength constraints in elite male rink-hockey player...
Ferraz, António; Santos, João Valente dos; Duarte-Mendes, Pedro; Nunes, Célia; Victorino, Samuel; Silva, Manuel Coelho e; Travassos, BrunoRink hockey is a highly specialized and physiological demanding sport with sparse research regarding the game and athletes’ characteristics. A cross-sectional study was developed to characterize the body composition and grip strength of elite male rink hockey players and to establish the relationship between ethnicity on body composition and grip strength. A sample of 100 elite rink-hockey athletes aged 26.59 ±...

Effects of exercise on cardiac function outcomes in women receiving anthracycli...
Antunes, Pedro; Esteves, Dulce; Nunes, Célia; Amarelo, Anabela; Fonseca-Moutinho, José; Afreixo, Vera; Costa, Henrique; Alves, Alberto; Joaquim, AnaBackground: we conducted a systematic review and meta-analysis of randomized controlled trials (RCTs) to evaluate the efficacy of exercise training on cardiac function and circulating biomarkers outcomes among women with breast cancer (BC) receiving anthracycline or trastuzumabcontaining therapy. Methods: PubMed, EMBASE, Cochrane Library, Web of Science and Scopus were searched. The primary outcome was change o...
Identification of key career indicators in portuguese football players
Monteiro, Ricardo; Monteiro, Diogo; Nunes, Célia; Torregrossa, Miquel; Travassos, BrunoThe aim of this study was to describe and identify the weight of some key career indicators (KCI) on the competitive level of retirement (professional vs. non-professional) of Portuguese football players. Three thousand five hundred retired Portuguese football players born between 1950 and 1989, and registered on Portuguese Football Federation were considered in this study. Descriptive analysis and a multivaria...
On the derivation of complex linear models from simpler ones
Dias, Cristina; Nunes, Célia; Mexia, JoãoTiago; Santos, CarlaLinear mixed models are useful in biology, genetics, medical research, agriculture, industry, and many other fields, providing a flexible approach in situations of correlated data. Based on the structure of the variance-covariance matrix, emerged a special class of linear mixed models, those of models with orthogonal block structure, which allows optimal estimation for variance components of blocks and contrast...
