Alinhamento Da Produção Científica Do Programa De Pós-graduação Em Medicina Tropical Da Ufpe às Necessidades Sociais De Saúde Tropical Em Pernambuco
Evaluates the contribution of the scientific production of the UFPE Post-Graduation Program in Tropical Medicine (2004 to 2012) with the social needs in tropical health in the state of Pernambuco. For this, use as reference the State Health Plan (2012-2015) developed by the State Government of Pernambuco. On the methodological aspect, this study is characterized as descriptive, and used the Scientometry the basis for measuring whether the publications of permanent researchers from the UFPE Post-Graduation Program in Tropical Medicine were aligned to the problems outlined in the State Health Plan. The methodological steps were: a) data collection training and scientific production of the researchers in the Lattes Platform of CNPq; b) issue identification of scientific literature conducted by researchers involved and mapping of tropical diseases cited in the State Health Plan; c) construction and application of interviews with researchers through a questionnaire. As main results, it is clear that research motivations are: a) adjustment of production to research lines established by the Program, and b) the opportunity to provide benefits to society, noting as well that the motivations for carrying out the surveys are social, having little infiluence of the private sector. About the alignment of themes produced with social needs in Tropical Health in the state of Pernambuco, it turns out that the program has been expanding the tropical disease concept of scope for infectious diseases, and for this reason, HIV appears at the top of the most representative themes.26218519
High throughput generated micro-aggregates of chondrocytes stimulate cartilage formation in vitro and in vivo
Cell-based cartilage repair strategies such as matrix-induced autologous chondrocyte implantation (MACI) could be improved by enhancing cell performance. We hypothesised that micro-aggregates of chondrocytes generated in high-throughput prior to implantation in a defect could stimulate cartilaginous matrix deposition and remodelling. To address this issue, we designed a micro-mould to enable controlled high-throughput formation of micro-aggregates. Morphology, stability, gene expression profiles and chondrogenic potential of micro-aggregates of human and bovine chondrocytes were evaluated and compared to single-cells cultured in micro-wells and in 3D after encapsulation in Dextran-Tyramine (Dex-TA) hydrogels in vitro and in vivo. We successfully formed micro-aggregates of human and bovine chondrocytes with highly controlled size, stability and viability within 24 hours. Micro-aggregates of 100 cells presented a superior balance in Collagen type I and Collagen type II gene expression over single cells and micro-aggregates of 50 and 200 cells. Matrix metalloproteinases 1, 9 and 13 mRNA levels were decreased in micro-aggregates compared to single-cells. Histological and biochemical analysis demonstrated enhanced matrix deposition in constructs seeded with micro-aggregates cultured in vitro and in vivo, compared to single-cell seeded constructs. Whole genome microarray analysis and single gene expression profiles using human chondrocytes confirmed increased expression of cartilage-related genes when chondrocytes were cultured in micro-aggregates. In conclusion, we succeeded in controlled high-throughput formation of micro-aggregates of chondrocytes. Compared to single cell-seeded constructs, seeding of constructs with micro-aggregates greatly improved neo-cartilage formation. Therefore, micro-aggregation prior to chondrocyte implantation in current MACI procedures, may effectively accelerate hyaline cartilage formation
Risk profiles and one-year outcomes of patients with newly diagnosed atrial fibrillation in India: Insights from the GARFIELD-AF Registry.
BACKGROUND: The Global Anticoagulant Registry in the FIELD-Atrial Fibrillation (GARFIELD-AF) is an ongoing prospective noninterventional registry, which is providing important information on the baseline characteristics, treatment patterns, and 1-year outcomes in patients with newly diagnosed non-valvular atrial fibrillation (NVAF). This report describes data from Indian patients recruited in this registry. METHODS AND RESULTS: A total of 52,014 patients with newly diagnosed AF were enrolled globally; of these, 1388 patients were recruited from 26 sites within India (2012-2016). In India, the mean age was 65.8 years at diagnosis of NVAF. Hypertension was the most prevalent risk factor for AF, present in 68.5% of patients from India and in 76.3% of patients globally (P < 0.001). Diabetes and coronary artery disease (CAD) were prevalent in 36.2% and 28.1% of patients as compared with global prevalence of 22.2% and 21.6%, respectively (P < 0.001 for both). Antiplatelet therapy was the most common antithrombotic treatment in India. With increasing stroke risk, however, patients were more likely to receive oral anticoagulant therapy [mainly vitamin K antagonist (VKA)], but average international normalized ratio (INR) was lower among Indian patients [median INR value 1.6 (interquartile range {IQR}: 1.3-2.3) versus 2.3 (IQR 1.8-2.8) (P < 0.001)]. Compared with other countries, patients from India had markedly higher rates of all-cause mortality [7.68 per 100 person-years (95% confidence interval 6.32-9.35) vs 4.34 (4.16-4.53), P < 0.0001], while rates of stroke/systemic embolism and major bleeding were lower after 1 year of follow-up. CONCLUSION: Compared to previously published registries from India, the GARFIELD-AF registry describes clinical profiles and outcomes in Indian patients with AF of a different etiology. The registry data show that compared to the rest of the world, Indian AF patients are younger in age and have more diabetes and CAD. Patients with a higher stroke risk are more likely to receive anticoagulation therapy with VKA but are underdosed compared with the global average in the GARFIELD-AF.

Determinação da digestibilidade de nutrientes através da técnica do "saco de nylon" mais pepsina
Procurou-se verificar se a digestão de alimento em saco de "nylon", acrescida por tratamento com pepsina, seria equivalente à digestão obtida pelo método direto clássico, o de coleta total de fezes, já determinado anteriormente com ovinos. Seguiu-se um delineamento experimental em blocos ao acaso, com 6 repetições e 4 tratamentos, ou seja, tratamento A: ração contendo 100% de feno de capim de Rhodes; B: 85% de feno de Rhodes mais 15% de farelo de côco; C: 70% de feno de Rhodes mais 30% de farelo de côco; e D: 100% de farelo de côco. O animal fistulado utilizado para teste foi um bovino adulto, macho, de raça holandesa; o tempo de permanência do saco de "nylon" no rume foi de 72 horas; e a dieta consistiu em feno de Rhodes à vontade mais 2kg de farelo de coco por dia. Os resultados foram analisados através de análise da variância e curvas de regressão, e a comparação entre métodos de digestibilidade pelo teste de Tukey. Houve influência da associação de alimentos sobre a digestibilidade da fibra bruta (FB) e dos extrativos não nitrogenados (ENN), mas não sobre as demais frações - matéria seca (MS), extrato etéreo (EE) e proteína bruta (PB). A digestibilidade da fibra diminuiu com a inclusão e o acúmulo do nível de farelo na dieta. Não houve equivalência consistente entre os métodos testados de digestiblidade, variando ou não conforme o nutriente e o tratamento considerado. De modo geral, a inclusão de aproximadamente 15% de farelo de côco (tratamento B) favoreceu o melhor aproveitamento da dieta."Nylon bag" technique, followed by 48 hours of chloridric pepsin digestion, was tried for determination of the digestibility of proximate nutrients of Rhodes grass hay (Chloris gayana, Kunth, cv. callide) and coconut caque meal, and compared with results from "in vivo" method. In a randomized blocks design, 100% of Rhodes grass, and mixtures of 85% and 70% of the grass hay with 15%, and 30% of coconut cake, and 100% coconut cake, made up four treatments (A, B, C and D, respectively). The coefficients of digestibility for Dry Matter and for proximate nutrients in treatments A, B and C, determined through nylon bags in bovine rumen, were compared to the coefficients determined by total faces collection, in sheep. It was observed and concluded that: a) Position of samples along the supoort-bars inside rumen, as well as dfferent periods of animal usage, had no influence on the results; b) The calculated proportions of coconut in the mixture to obtain best digestibility were 17.48% for Dry Matter, 21.10% for Ether Extract, 29.01% for Crude Protein, and 16.49% for Non Nitrogenous Extrat. Crude Fiber digestibility decreased linearly as the coconut proportion in the mixture increased; c) "Nylon bag" and "in vivo" methods gave similar coefficients of digestibility for Crude Fiber for all treatments; for other nutrients, however, there were differences depending on treatments; d) TDN values for coconut cake meal, determined through "nylon bags" were 68.76% taking the average coefficients of digestibility from treatments B and C, and 68.08% from treatment D; "in vivo", the average from B and gave 71.06% of TDN; such a small difference in NDT suggests to have had no interference of foods on digestibility; e) NDT calculate for Rhodes grass hay was 58.38% "in nylon bags", and 44.81% "in vivo", when treatment A was the only one considered; thus, it could be concluded that nylon bag plus pepsin method did not work for Rhodes hay
