- Assessment of ambient assisted living systems for patients with mild cognitive impairmentPublication . Herzog, David Josef; Moreira, Rui Silva; Torres, JoséAccording to the World Health Organization, about 50 million people worldwide suffer from dementia. Ten million new cases added every year. Mild Cognitive Impairment (MCI) affects more than 15% of the population aged 65. Technological solutions, such as smart home technology with ubiquitous computing devices, 24/7 telemedical observation and support can alleviate the growing problem and lower pressure on the healthcare system. This approach is also preferable for homecare patients in distant and rural areas. MCI patients are mostly home-based. Ambient Assisted Living (AAL) systems provide tools for automatic registration of vital signs and other medically and socially important information. AAL system for MCI patients is a logical answer to the problem. At the same time, many of the proposed AAL systems are proprietary, technically complicated and have a high price tag for implementation and service. Also, some proposed technical solutions not entirely reflect the opinion of healthcare stakeholders. The current study was proposed as a way to bridge the possible differences in the positions. An online anonymous questionnaire for healthcare professionals was created to prove or disprove the number of interconnected hypotheses about the necessity and feasibility of AAL system for MCI patients. The main focus was made on the hypotheses: "There is necessity of AAL systems for the healthcare" and "AAL systems are capable of providing assistance for patients with Mild Cognitive Impairment". The questionnaire was presented to more than three hundred potential respondents. Around a hundred and twenty agreed to fill it, and sixty completed the whole questionnaire. Results were analyzed to produce some directions guideline for future technical applications of AAL systems for MCI patients and future research. Descriptive statistics show support for the implementation of general AAL and variants for MCI patients. Comparative analysis of ordinal data for specific groups of respondents is done with help of non-parametric tests. Mann–Whitney–Wilcoxon test and Kruskal-Wallis test are applied. Table questions results are analyzed with chisquare for frequency tables. Group analysis demonstrated relative positive uniformity in of responses in the support of AAL of MCI patients.
- Osteotomia: instrumentos de corte de alta versus baixa rotação – revisão narrativaPublication . Andrade, Renato Santos Pinto de; Pereira, JorgeO presente estudo teve como objetivo realizar uma análise sobre o procedimento cirúrgico conhecido como osteotomia, muito utilizado na implantodontia, considerando a utilização de instrumentos de alta versus baixa rotação. Para tanto, realizou-se a revisão narrativa, com artigos científicos que abordassem a comparação entre as duas técnicas. Verificou-se que são poucos os estudos que realizam a comparação entre as técnicas, de modo que os resultados aqui descritos podem ajudar na prática odontológica. Os resultados sugerem que instrumentos de baixa rotação e com refrigeração apresentam melhores resultados e promovem mais segurança no procedimento por permitir maior precisão e menor temperatura, fator que pode afetar o tecido ósseo e, consequentemente, a osseointegração. As principais análises abordam o uso da técnica em animais, de forma que há a necessidade de estudos clínicos futuros com humanos para corroborar com os achados deste estudo.
