In relation to the INDEL association with tumor node metastasis(TNM) stage risk, the Ins alleles of ACE, HLAG and TP53(6 bp INDEL) were associated with higher TNM stage. Furthermore, regarding INDEL association with relapse risk, the Ins alleles of ACE, HLAG, and UGT1A1 were associated with early relapse risk, as well as the Del allele of TYMS. Regarding INDEL association with death risk before 10 years, the Ins allele of SGSM3 and UGT1A1 were associated with death *** The INDEL variations in ACE, UCP2, TYMS, IL4, NFKB1, CASP8, TP53, HLAG, UGT1A1, and SGSM3 were associated with CRC risk and clinical features in an admixed population. These data suggest that this cancer panel might be useful as a complementary tool for better clinical management, and more studies need to be conducted to confirm these findings.

An Overview of the Amazonian Craton Evolution: Insights for Paleocontinental Reconstruction

引用

International Journal of Geosciences 2015年第9期6卷 1060-1076页

作者： Mauro Cesar Geraldes Armando Dias Tavares Anderson costa dos santos Rio de Janeiro State University Maracana Rio de Janeiro Brazil

The Amazonian craton major accretionary and collisional processes may be correlated to supercontinent assemblies developed at several times in the Earth history. Based on geologic, structural and paleomagnetic evidence paleocontinent reconstructions have been proposed for Archean to younger times. The oldest continent (Ur) was formed probably by five Achaean cratonic areas (Kaapvaal, Western Dhawar, Bhandara, Singhhum and Pilbara cratons). Geologic evidences suggest the participation of the Archaean rocks of the Carajás region in the Ur landmass. Supercontinental 2.45 Ga Kenorland amalgamation is indicated by paleomagnetic data including Laurentia, Baltica, Australia, and Kalahari and Kaapvaal cratons. There is no evidence indicating that Amazonian craton was part of the Kenorland supercontinent. From 1.83 Ga to 1.25 Ga Columbia and Hudsonland supercontinents including Amazonian craton were proposed based on NE portion of the Amazonian craton (Maroni/Itacaiunas province) connection with West Africa and Kalahari cratons. Rodinia supercontinent reconstructions show Amazonia joined to Laurentia-Baltica as result of 1.1 Ga to 1.0 Ga fusion based on the Sunsas-Aguapei belts and Greenville and Sveconorwegian belts, respectivelly. The large Late Mesoproterozoic landmass included also Siberia, East Antartica, West Nile, Kalahari, Congo/Sao Francisco and Greenland. The 750 - 520 Ma Gondwana assembly includes most of the continental fragments rifted apart during the break-up of Rodinia followed by diachronic collisions (Araguaia, Paraguay and Tucavaca belts). The supercontinent Pangea is comprised of Gondwana and Laurentia formed at about 300 - 180 Ma ago. The Amazonian craton margins probably were not envolved in the collisional processes during Pangea because it was embebed in Neoproterozoic materials. As consequence, Amazonian craton borders have no record of the orogenic processes responsible for the Pangea amalgamation.

Prescription and Delivery of Enteral Nutrition for ICU Patients: A Case Study of a Hospital in the Interior of Brazil

引用

Food and Nutrition Sciences 2023年第10期14卷 880-896页

作者： Valtemir Paula de Oliveira Junior Daiane costa dos santos Sibele santos Fernandes Mariana Buranelo Egea Campus Rio Verde Goiano Federal Institute of Education Science and Technology Rio Verde Brazil Institute of Tropical Pathology and Public Health Goiás Federal University (UFG) IPTSP-UFG Goiania Brazil School of Chemistry and Food Federal University of Rio Grande Rio Grande Brazil

Background: The objective of the present study was to evaluate during one year the total delivery of volume, calories, and proteins and compare them with the total prescribed to ICU patients using ENT (Enteral Nutrition Therapy) exclusively. Methods: Data on the prescribed or infused volume, calories, and protein, as well as their respective needs for each individual, were collected. Anthropometric parameters and age data were also collected from the medical records of 41 patients admitted to the intensive care unit. Results: Prescribed versus infused enteral diet volume was presented in 5 weeks which corresponds to the maximum duration of ICU treatment. Regarding sampling, the majority corresponded to elderly people (>64 years old) and males (63.4%). The total average prescribed was 719.2 mL of enteral diet on an average of 649.7 mL delivered. In addition, there was no significant difference between the prescribed and delivered volume, caloric value, and protein content of the diet only in the last week of hospitalization, which corresponded to the range of 29 - 36 days. Several factors make it difficult to reach the patient’s caloric and protein recommendations. Most of the reasons are not recorded, corresponding to 57.1%, indicating the difficulty of assessing the inadequacy of the prescribed and delivered volume. Conclusion: To our knowledge, this is the first time that a prescription vs. delivery assessment has been carried out for patients in the Brazilian Midwest. In addition, although our research is a difficulty reported worldwide (in most hospitals), we also provide opportunities for how the problem was solved in our case, which may contribute to other cases.

Animal Nutrition 2019年第2期5卷 163-173页

作者： Tiago T.dos santos Sthéfanie C.Dassi Celia R.C.Franco Cleber R.V.da costa Sophie A.Lee Ana V.Fisher da Silva Universidade Federal do Parana Curtiba81531-900Brazil Department of Cell Biology Universidade Federal do ParanaCuritiba81531-900Brazil AB Vista MarlboroughWiltshireSN8 4ANUnited Kindom Department of Cell Biology Universidade Federal do ParanaCuritiba81531-900Brazil

An experiment was designed to determine the influence of fibre and betaine on the development of the intestine, liver and pancreas of broilers from hatch to 14 d of age. A total of 250-day-old Cobb 500 male broilers were allocated to 16 cages with 15 broilers each. Treatments were arranged in a 2 x 4 factorial design, consisting of 2 feed formulations(low and high fibre diets) and 4 levels of betaine(0,1, 3 or 5 kg/t). At hatch, 10 birds in total were euthanised, and samples of the liver, pancreas, yolk sac and intestine were collected for reference of the analysed parameters before the start of the *** d 4.9 and 14, 5 birds per cage(10 birds per treatment) were selected, euthanised and treated as the same as the birds at hatch. Villus height and width and crypt depth were determined on the duodenum samples, and absorptive area was calculated. The number of enterocytes in mitosis at the villus was determined by a positive reaction to antibody for Ki67 protein, and fused villus was evaluated visually. The relative weight of the yolk sac reduced(P < 0.05) as birds aged while the intestine and liver reached a maximum(P < 0.05) at around d 4 and the pancreas at d 9. Birds fed the high fibre diet had greater feed intake, lower relative weight of the pancreas and higher villus(P < 0.05) than birds fed the low fibre diet. Villus width increased(P < 0.05) at 4 d of age, and this was associated with fused villus. Betaine inclusion reduced(P < 0.05) villus width, increased(P < 0.05) villus size and absorptive area, and reduced(P < 0.05) the number of enterocytes with positive reaction for the antibody *** inclusion reduced the width and increased the absorptive area and the villus height of the duodenum of birds up to 14 d of age. The higher fibre diet increased feed intake and villus height, yet reduced pancreas relative weight, while not affecting body weight gain. This response was possibly due to a dilution effect of the fibre, reducing nutrient absorption

AIM: To evaluate in bile duct ligated rats whether there were progressive alterations of renal function without changes in histopathology. METHODS: Male Wistar rats were submitted to sham-surgery or bile duct ligation (BDL) and divided according to the post-procedure time (2, 4 and 6-wk). To determine renal function parameters, rats wereplaced in metabolic cages and, at the end of the experiment, blood and urine samples were obtained. Histology and hydroxyproline content were analyzed in liver and renal tissue. RESULTS: Rats with 2 wk of BDL increased free water clearance (P = 0.02), reduced urinary osmolality (P = 0.03) and serum creatinine (P = 0.01) in comparison to the sham group. In contrast, rats at 6 wk of BDL showed features of HRS, including signif icant increase in serum creatinine and reductions in creatinine clearance, water excretion and urinary sodium concentration. Rats with 4 wk of BDL exhibited an intermediate stage of renal dysfunction. Progressive hepatic f ibrosis according to post-procedure time was confirmed by histology. The increased levels of liver hydroxyproline contrasted with the absence of structural changes in the kidney, as assessed by histology and unchanged hydroxyproline content in renal tissue. CONCLUSION: Our data show that BDL produced progressive renal dysfunction without structural changes in the kidney, characterizing HRS. The present model will be useful to understand the pathophysiology of HRS.

Nutritional Screening Tools in Institutionalized People: A Case Study of Using Nutritional Risk Screening (NRS 2002) and Mini Nutritional Assessment (MNA)

引用

Food and Nutrition Sciences 2024年第7期15卷 565-575页

Nutritional status expresses the physiological and nutritional needs to maintain the composition and adequate functioning of the organism. NRS 2002 and MNA protocols were applied to short-term institutionalized patients in Rio Verde (Brazil). Older adults and people with special needs of all ages, both sexes, regardless of possible pathology they may have, except if it causes contagion, were included, patients duly authorized by the person responsible for the institution and who were able to undergo evaluation. Thirty-eight patients from the institution were evaluated, of which ten were excluded from the research according to pre-established criteria. More than 50% of participants were male, with an overall average age of 63.43 years. The characteristics related to nutritional status by NRS 2002 and MNA showed that the risk of malnutrition and its absence are associated with a wide age range. The MNA presents a more nuanced nutritional risk classification, showing that even 61% of the 96% of participants who would be out of nutrition risk, according to the NRS 2002, are “at risk of malnutrition”. Applying the MNA can demonstrate more conservative results than the NRS 2002.

Driving forces on the landscape require regional management and/or local actions, together with other external factors. To operationalize this approach, this paper carried out a comparative analysis of the naturalness dynamics of the Jacaré-Guaçu and Jacaré-Pepira watershed, based on land use/cover changes and a structural indicator of the landscape, over the 10-year (2004-2014), as support opportunities for improving its environmental planning and management. Land use/cover dynamics were obtained based on screen digitizing of LandSat imagery, using polygon manual digitalization. Naturalness scenarios of the watersheds, over the 10-year (2004-2014), were obtained based on Urbanity Indicator, which evaluates how much the natural landscapes are dominated by altered systems. The total area of watersheds showed a predominantly scenario, induced by anthropogenic agricultural and non-agricultural expansion areas, mainly by conversion of other land use/cover types in sugarcane cultivation. Despite the increase in natural vegetation areas, over the 10-year (2004-2014), Jacaré-Guaçu and Jacaré-Pepira watersheds are far from a sustainable condition. However Jacaré-Guaçu watershed presents a scenario of more committed naturalness due to the increase in Urbanity Index values ≥ 0.7. The historical process of land use occupation for agricultural production remains the main driving force of naturalness changes, occupying more than 70% of the total area of watersheds. These results have significant implications for fast urbanizing municipalities in providing key information about long term land use impact on the watershed structure and function, making it possible for policy makers, scientists and stakeholders to identify land uses which are hindered or enhanced under various scenarios of land use change over the time, and making it possible to explore the trade-offs between them to improve watershed management.
