This work aims to describe differences between younger (<65 years) and older (>= 65 years) pre-frail and frail HF outpatients regarding their nutritional, functional and clinical statuses.Methods: In this cross-sectional study, a sample of 99 HF frail and pre-frail patients (aged 24-81 years, 38.4% women, 21.2% frail, 59.6% <65 years) was recruited from an HF outpatients' clinic in northern Portugal. Muscle mass was estimated from mid-upper arm muscle circumference. Weight status was assessed using body mass index. Hand grip strength and gait speed were measured. Medical records were reviewed. Associations between participants' characteristics and age were calculated using binary logistic regression.Results: Age was associated with hand grip strength (OR=0.90), gait speed (OR=0.01) and dia-betes (OR=4.95). Obesity, muscle mass or heart failure functional classes were not associated with age categories.Conclusion: There is an overall lack of differentiation between younger and older HF patients with the frailty phenotype. Therefore, frailty phenotype should be assessed in all patients, regardless of age. Hand grip strength seems to be a good predictor for older age and more studies are needed to define age-specific hand grip strength cut-offs for HF populations.

Os instrumentos atuais de medição deste conceito têm a desvantagem de depender bastante da capacidade dos participantes para ler ou fazer cálculos matemáticos, dificultando a sua aplicação em indivíduos com baixa escolaridade. Avaliam apenas conhecimentos teóricos, pelo que também não refletem diretamente a relação entre estes conhecimentos e a capacidade de fazer escolhas alimentares adequadas. O projeto NUTLY pretendeu ultrapassar algumas destas limitações, através do desenvolvimento de um instrumento de medição da literacia nutricional baseado em fotografias, e validação para aplicação na população adulta residente em Portugal. O instrumento NUTLY tem como premissa a comparação de alimentos com diferentes perfis nutricionais, focando-se em conhecimentos e competências com relevância prática para a escolha alimentar. O objetivo do presente artigo é divulgar esta ferramenta entre profissionais de saúde a exercer funções em Portugal, bem como discutir as suas principais potencialidades de aplicação (nomeadamente nos contextos da educação alimentar, saúde pública, investigação científica e nutrição clínica).</jats:p> 2024-01-01T00:00:00Z https://hdl.handle.net/10216/167892 Title: Vascular dysfunction in adipose tissue: its impact on type 2 diabetes and cancer 2024-01-01T00:00:00Z https://hdl.handle.net/10216/162225 Title: Amarramos-te ali à cadeira: perceções sobre os ofensores e o risco de violência na idade avançada Abstract: This article analyses the experiences and perceptions of a sample of people over 60 about the most frequent type of violence in old age, the risk factors, the offenders and the reactions to abuse. A mixed study was carried out with the sequential application of 677 questionnaires and 45 interviews. The results show that older people are mainly victims of psychological abuse and financial exploitation; the type of abuse varies according to the type of aggressor; and that machismo, ageism, mental health problems, addictive behaviours and social isolation are risk factors for violence. Health and justice professionals are perceived as those to whom victims should turn and confide. Description: Este artigo analisa as vivências e perceções de uma amostra de pessoas com mais de 60 anos sobre o tipo de violência mais frequente na idade avançada, os fatores de risco, os ofensores e as reações aos abusos. Foi realizado um estudo misto, com a aplicação sequencial de 677 questionários e 45 entrevistas. Os resultados mostram que as pessoas mais velhas são vítimas principalmente de abuso psicológico e de exploração financeira; o tipo de abuso varia consoante o tipo de agressor/a; e que o machismo, idadismo, problemas de saúde mental, comportamentos aditivos e o isolamento social são fatores de risco de violência. Os profissionais de saúde e da justiça são percecionados como aqueles a quem as vítimas devem recorrer e confiar. 2024-01-01T00:00:00Z https://hdl.handle.net/10216/134320 Title: MONITORIA: The start of a new era of ambulatory heart failure monitoring? Part II - Design Abstract: Introduction: Heart failure (HF) represents a huge financial and economic burden worldwide. Some authors advocate that remote monitoring should be implemented to improve HF management, but given its increasing incidence, as well as its morbidity and mortality, a question still remains: are we monitoring it properly? There is no shortage of literature on home monitoring devices, however, most of them are designed to monitor an unsuitable array of variables and, to the best of our knowledge, there are no large randomized studies about their impact on morbidity/mortality of HF patients. Objective: Description of a novel monitoring device. Methods: As a solution, we designed MONITORIA (MOnitoring NonInvasively To Overcome mortality Rates of heart Insufficiency on Ambulatory). Results: This is a multimodal device that will provide real time monitoring of vital, electrophysiological, hemodynamic and chemical signs, transthoracic impedance, and physical activity levels. The device is meant to perform continuous analysis and transmission of all data. Significant alterations in a patient's variable will alert the attending physician and, in case of potentially life-threatening situations, the national emergency medical system. The MONITORIA device will, also, have a function that sends shocks or functions as a pacemaker to treat certain arrhythmias/blockades. This function can be activated the very first time the patient utilizes it, based on their risk of sudden cardiac death. Discussion/Conclusions: MONITORIA is a promising device mostly because it is included in a follow-up program that takes into account a multi-perspective feature of HF development and is based on the real world patient, adapting innovations not to the disease but rather to the patients.

In periradicular surgery, the use of ultrasonic tips ensures high-quality root-end cavity preparations, enables the performance of a 90-degree apicoectomy, and removes larger amounts of contaminated material. The authors reviewed in vitro and in vivo studies in the literature and evaluated root-end cavities prepared with burs or ultrasonic tips using scanning electron microscopy. 2008-01-01T00:00:00Z https://hdl.handle.net/10216/126794 Title: Nutrition UP65 educational strategies: health professionals qualification course 2019-01-01T00:00:00Z https://hdl.handle.net/10216/126790 Title: Added and Free Sugars: review in the literature of estimated intakes and its main food sources 2019-01-01T00:00:00Z https://hdl.handle.net/10216/125862 Title: Segmentação automática de imagens doppler transversais modo-b da bifurcação carotídea / Automatic segmentation in transverse ultrasound bmode images of the carotid artery Abstract: Ultrasound imaging is extremely important for the assessment of disease severity in the carotid arteries. The high complexity of irregular structures in transverse ultrasound images of abnormal bifurcation of the common carotid artery brings tremendous difficulty to segmentation and identification of vulnerable atherosclerotic plaques. Automatic algorithms for image segmentation provide results minimizing the variability caused by subjective decisions and different operators. The proposed algorithm for automatic segmentation of B-mode transverse images of the carotid bifurcation facilitates structure selection for further analyses and provides an evaluation performance of the methodology and a means for comparing different algorithm settings. Patient-specific Doppler imaging is used to illustrate the new developed methodology. 2018-01-01T00:00:00Z https://hdl.handle.net/10216/25729 Title: Análise da fusão dentinária promovida pelo laser Nd:YAG com e sem remoção do delta apical 2006-01-01T00:00:00Z https://hdl.handle.net/10216/25706 Title: Laseres de CO2, Er:YAG e Nd:YAG em cirurgia parendodôntica 2003-01-01T00:00:00Z https://hdl.handle.net/10216/25753 Title: A percepção do belo e a proporção divina Abstract: The aesthetic knowledge concerning the face one is widely important for the professionals of the Dentistry area and, moreover, it is of interest of the people of a general form. It has a trend, while professional, of if imposing the aesthetic values when really can be to observe the values of the proper individual. Many are the studies that present, of clear form, the differences between the individuals, as patient or people independent, how to its preferences, if compared with the ideas of beauty of the professionals of different areas. Being thus, objective in this chapter to integrate the reader to the presentation of the aesthetic one, not only in the scientific aspect, as measurable and quantitative object, as also in the artistic and social aspect. How to the beauty, the perception that if has of the things in day-by-day is basically utilitarian and conceptual. It has a bigger trend in if to perceive the things by means of the concepts proceeding from the language of the one that really eat is capable to sensitize our directions. However, it fits to remember that the language classifies and appraises the feelings, but is extremely impotent to describe them. It must always be had in mind that is in the sensible one - and not in the conceptual one, in the intellectual - that inhabits the being of the aesthetic object. 2007-01-01T00:00:00Z https://hdl.handle.net/10216/25796 Title: Análise de duas metodologias na aferição de infiltração por corante em apicoplastias com retrobturações Abstract: Different methods have been used in studies on marginal infiltration caused by staining dye with the purpose of evaluating the efficiency of dental materials employed in apicoplasties with retrograde root filling. Apicoplasty consists of flattening the root apex eliminating the need of root amputation, maintaining its correct shape. The objective of the present study was to evaluate the results of infiltration of rhodamine B 1% in an experimental group, comparing the dye depth penetration with the impregnation area in the same samples that underwent apicoplasties with retrograde root filling. The samples included 12 human upper canine teeth endodontically treated and retro-obturated using MTA. For sample analysis, the Image Tool® software was used to perform computerized morphometry. Results showed a low standard deviation (4.79) regarding area measurement, and high standard deviation (15.05) in terms of measurement of the dye depth penetration. The Mann-Whitney test showed statistically significant differences between the groups (p < 0.0001). The use of the dye stained area, instead of dye depth penetration, proved to be a better choice for measuring marginal infiltration scores according to the methodological parameters used in the present study. 2010-01-01T00:00:00Z https://hdl.handle.net/10216/113215 Title: Rede de voluntários do projeto Nutrition UP 65: perspetivas do trabalho voluntário em intervenção comunitária e saúde pública 2018-01-01T00:00:00Z https://hdl.handle.net/10216/25734 Title: Analgesia Preventiva, ao Teste do Formol, por Terapia Laser em Ratinhos Abstract: The present research assessed the analgesic effect of the laser therapy in healthy tissues of 10 mice divided into two groups: - L: red laser irradiation (665 nm, 30 mW, 10 J/cm2, 334 s). - C: control laser irradiation (334 s).
