title: Effect of the diet on performance characteristics and quality of meat fat of lamb by principal component analysis

description: ABSTRACT. The objective of this study was to evaluate the effect of use of agroindustrial co-products in the diet of lambs on the performance and nutritional quality of meat fat. Twenty lambs were distributed into four experimental groups: control diet (C) or diets containing cottonseed (CS), sunflower meal (SFM), and castor cake (CC). During the experimental period, data on dry matter consumption (DMC) and total weight gain (TWG) were collected. After slaughter, samples of Logissimus dorsi (LD) muscle were taken for fatty acids and cholesterol analysis. Diets C and CS provided similar characteristics of fat quality and animal performance. However, SFM and CC diets tend to form isolated groups, with different fat and performance characteristics. The SFM diet results in meat with a higher saturated fatty acids and cholesterol content. The CC diet is related to improved performance characteristics and lower cholesterol content. In conclusion, the inclusion of CC in the experimental diets provided, in the proportions used in this experiment, better characteristics of animal performance and meat fat quality.

title: Inclusion of vegetable oils in diets of broiler chicken raised in hot weather and effects on antioxidant capacity, lipid components in the blood and immune responses

description: ABSTRACT. The aim of this study was to assess the effects of vegetable oils on the antioxidant capacity, blood lipid components and immune responses in chickens raised in hot climate. In a completely randomized design, 300 chicks were assigned to four treatments and five replicates with 15 chicks per each. The highest concentration of malondialdehyde was found in broilers fed palm oil (p &lt; 0.05). Chickens fed corn oil had the lowest and those fed flaxseed oil had the highest antioxidant enzymes activities (p &lt; 0.05). The highest hepatic Alanine-transferase and Aspartate-transferase was found in chickens fed corn oil and the lowest levels in those received flaxseed and olive oils (p &lt; 0.05). The highest hypersensitivity was in chickens fed palm oil and the lowest was for olive oil. The highest antibody titer against sheep red blood cells was found in chickens fed flaxseed oil and the lowest titer was for those received palm oil (p &lt; 0.05). The highest triglyceride, cholesterol and very low density lipoprotein and the lowest high density lipoprotein was found in chickens fed palm oil and vice versa for flaxseed and olive oils. Olive and flaxseed oils had beneficial effects on antioxidant activity and lipid attributes and palm oil had detrimental effects on these parameters that related to the poultry health.

title: Floristic diversification of spreading liverseed grass pasture according to different cutting intensities, obtained by grazing simulation

description: ABSTRACT. This study aimed to evaluate the impacts of different forage cutting intensities, obtained by grazing simulation, on the floristic diversity and productivity of a pasture cultivated with spreading liverseed grass. The experiment was set up in a randomized block design, with four replications and treatments arranged in a 5 × 2 factorial scheme, with five levels of cutting intensity of the simulated grazing (0, 25, 50, 75, and 95% of the forage canopy) associated with two levels of weed coexistence (presence and absence). The evaluations of floristic diversity, number of individuals, and total dry matter of weeds were obtained at 15, 30, 45, 60, and 90 days after grazing simulation (DAGS). All plots were evaluated at the end of the experimental period (90 DAGS) for the amount of dry biomass produced by the pasture. The results showed that higher forage cutting intensities, obtained by grazing simulation, increased the floristic diversity, the number of individuals, and the dry matter accumulated by weeds in a pasture grown with spreading liverseed grass, reducing by up to 56% the production of total dry matter of the forage.

title: Functional assessment of patients with cervical myelopathy who underwent surgical treatment

description: OBJECTIVE: Evaluate and correlate the functional response of patients with cervical myelopathy with the current clinical scores in patients who underwent surgical treatment. METHODS: We analyzed medical records of 34 patients with cervical myelopathy who underwent four different types of surgery. All patients were evaluated preoperatively and postoperatively with the application of the JOA and Nurick questionnaires. RESULTS: Functional clinical improvement was statistically significant. The mean preoperative JOA was 8.5 ± 3.06 and 10.7 ± 3.9 in the postoperative; Nurick was 3.2 ± 1.1 preoperatively and 2.8 ± 1.3 postoperatively. CONCLUSION: There is benefit with the surgical procedure in patients with cervical myelopathy. The neurological function after surgery depends on the previous function (the higher the duration of the previous symptoms, the greater the progression of the disease and, therefore, worse the neurological function) and the age is not a relevant factor of improvement, as already shown in other series. The clinical functional improvement of patients is visible with surgical treatment, regardless of surgical technique.

title: Bromatological composition and ruminal degradability of Xaraés palisade grass under grazing in integrated systems

description: ABSTRACT. To evaluate the bromatological composition and ruminal degradability of dry matter (DM), crude protein (CP), neutral detergent fiber (NDF) and acid detergent fiber (ADF) of Xaraés palisade grass (Urochloa brizantha ‘Xaraes’ syn Brachiaria brizantha) under grazing in integrated crop, livestock (ICL), and forest (ICLF) systems, we conducted an in situ degradability trial in randomized blocks with three non-lactating 3/4 Gyr × 1/4 Holstein cows, provided with ruminal cannula. The management of Xaraés palisade grass was similar in both systems, differing only regarding shading in the ICLF system provided by eucalyptus trees (average 65% crown cover). Grass samples were incubated for 0, 3, 6, 9, 12, 24, 36, 48, 72, and 96 hours. Considering the passage rate 2% h-1, the Xaraés palisade grass of ICL system had greater NDF effective degradability in relation to ICLF (46.38 vs 44.98%). However, the palisade grass CP potential degradability was greater in the ICLF than in the ICL system (68.92% vs. 65.40%). The presence of trees in the pasture has effect on nutritional traits of the Xaraés palisade grass, increasing its protein content and degradability and reducing its fiber degradability.

title: The effect of fairy shrimp “branchoneta” (Dendrocephalus brasiliensis) as the initial diet of tambaqui postlarvae

description: ABSTRACT. The effect of fairy shrimp “branchoneta” as the first exogenous feed for tambaqui postlarvae was evaluated. A hundred and eighty larvae were distributed in 12 aquariums, containing 1.5L of water and the stocking density was 10 larvae per liter. The trials lasted for 20 days and postlarvae were submitted to three diets (T1: Commercial feed, T2: branchoneta, and T3: Commercial feed with branchoneta), with a completely randomized design with four replicates for each treatment. During the trials, the water quality parameters were kept within ideal conditions for the species. The tambaqui postlarvae submitted to T2 and T3 showed better survival rates respectively. Regarding the postlarval development, larvae fed with only branchoneta had a better final weight (3.48 mg), daily weight gain (0.14 mg day-1), and the best specific growth rate (8.62%). The results also showed that the tambaqui postlarvae fed with only commercial feed developed less efficiently due to lower rates of survival and growth. The present study indicates that the branchoneta promoted greater development and survival rates of the tambaqui postlarvae and therefore, it presents good potential as a live food for the species.

title: Evaluation of chronic low back pain in osteoporotic patients in treatment with teriparatide

description: OBJECTIVE: The objective was to assess the improvement of chronic low back pain in osteoporotic patients treated with teriparatide (TPTD). METHODS: This was an observational study with a convenience sample of 21 patients with osteoporosis using TPTD, 20 mcg/day, between 2006 and 2010, with chronic low back pain (more than three months). Dorsolumbar radiographs and bone densitometry (DXA) were performed before and after treatment. For pain measurement the VAS pain scale was used. Data were entered in Excel and processed in STATA/SE 8.0 with Chi2 square or Fisher (p &lt; 0.05). RESULTS: twenty-one patients aged 40-90 (mean 70 years), eight (40%) had senile osteoporosis and thirteen (60%) had osteoporosis secondary to medications. Seventeen (80%) had previous dorsolumbar fractures. Ten (47.5%) used TPTD for 24 months, six (27.5 %) used the medication for 18 months, four (20%) for 12 months and one (5%) for six months. Eight patients (40%) received previous anti-reabsortive therapy. Thirteen patients (60%) exhibited bone mass gain between 0% and 9% while eight (40%), between 10% and 15%. The final average VAS was 2.6 representing an improvement of 4.7 (p&lt; 0.05). CONCLUSION: There was a significant reduction in the severity of low back pain with the use of TPTD (initial mean VAS: 7.3, final VAS: 2.6, improvement: 4.7).

title: Radiographic evaluation of the use of transverse traction device in vertebral arthrodesis for degenerative diseases

description: OBJECTIVE: Perform radiographic analysis of the use of Transverse Traction Device (DTT) with respect to fusion rate in patients submitted to vertebral arthrodesis for degenerative lumbar diseases. METHODS: We selected x-ray images on anteroposterior, lateral and oblique views and with maximum flexion and extension dynamics of 23 patients submitted to posterolateral arthrodesis of the lumbar spine with a minimum follow-up period of six months. The images were evaluated and classified by the Linovitz's system by two spine surgeons. RESULTS: We evaluated the radiographs of 23 patients after the minimum postoperative period of 6 months and of these, 11 have used DTT. With regard to the consolidation rate, seven patients (63.6%) in the group of DTT were classified as fusion as well as six patients (50%) who were not submitted to the treatment. There was no statistical difference between the groups regarding the consolidation rate. CONCLUSION: The use of transverse traction device in this study showed no significant difference in the rate of consolidation in radiographic evaluation. Studies on the effective participation of this device in the stability of pedicle fixation systems are still lacking in the literature.

title: Quality of life in patients with multiple myeloma treated with percutaneous vertebroplasty

description: OBJECTIVE: To determine the quality of life in patients with multiple myeloma treated with vertebroplasty. Multiple myeloma has a prevalence of 1% in all neoplastic diseases and 10% of hematological malignancies. Bone pain is the initial symptom in most cases. METHODS: A series of cases study was conducted. Patients were assessed by the Karnofsky scale to measure its functionality, the WHO analgesic scale to assess the type of analgesic and visual analog scale (VAS) and the Oswestry questionnaire for pain. RESULTS: Of 24 patients, 10 were cases (vertebroplasty) (41.7%) and 14 were controls (conservative) (58.3%), 13 (54.2%) were female and 11 (45.8%) male, with an average age of 60 years (SD = 12) and 63 kg of average weight (SD = 12), mean height of 1.59 cm (SD = 9) and mean body mass index of 24.8 (SD = 3.7). Survival was obtained from the time of diagnosis to death, and 2 (8.3%) patients died within the first 2 years and 1 (4.2%) after 3 years. CONCLUSIONS: Patients with MM who have vertebral fractures are excellent candidates to undergo vertebroplasty, because this represents a greater benefit in their quality of life, which has a direct impact on their level of functionality, giving them greater self-sufficiency and reducing their pain because of the benefits of the thermogenic effect of vertebroplasty.

title: Frisbee - the first artificial cervical disc of 3RD generation

description: OBJECTIVE: The current cervical disc arthroplasty is limited by postoperative facet joint arthritis, heterotopic ossification and segmental kyphosis. The total Frisbee disc, which has an upper convex/concave non-spherical surface and a lower flat sliding surface, is a new approach for improved outcomes. Prior to clinical application, safety and suitability tests are required. METHODS: The Frisbee is the first 3rd generation disc according to a new classification of total disc because it can precisely mimic the segmental ROM, including the soft limitation of axial rotation. The ISO 18192-1 test was carried out to determine the rate of wear debris. A FE model was used to assess the safety of prosthetic components. In the sagittal plane several variables to determine the most favorable lordotic angle were evaluated. RESULTS: Two angled prosthetic plates are safer than one sliding angled core to prevent the displacement. The lordosis of 7° of the Frisbee leads to kyphosis of no more than 2° without reduction of the ROM. The wear rate of the Frisbee is five times smaller compared to an FDA-approved disc with a spherical sliding surface. CONCLUSIONS: Based on the test results, the clinical application of Frisbee can now be studied. The postoperative kyphosis observed with other devices is not an issue with the Frisbee design. Physiological ROM is combined with the significant reduction of wear debris. For these reasons the Frisbee has the potential to provide a better balanced segmental loading reducing the degeneration of the joint surface and heterotopic ossification.

title: Migrated pharyngeal fish bone causing spondylodiscitis. Case report

description: Ingestion of foreign bodies is a common problem seen at emergency rooms and frequently involves chicken and fish bones. There are few cases of migrated foreign bodies through the retropharynx causing infectious process in the area but no one, despite the proximity, causing spondylodiscitis. Perhaps such condition is attributed to the integrity of the longus colli fascia covering and protecting the cervical spine. We described the first case of spondylodiscitis due to a foreign body (saw-toothed fish bone) that penetrated the longus colli fascia and carved into vertebral body C3.

title: Basilar invagination secondary to hypoplasia of the clivus - Is there indication for craniocervical fixation?

description: The posterior fossa decompression is a form of treatment suggested for patients with basilar invagination (BI) secondary to hypoplasia symptomatic of the clivus and atlantoaxial alignment preserved. Based on the fact that the worsening of cranial-cervical kyphosis (decrease of clivus-canal angle to less than 150o) can result in anterior brainstem compression, we propose that some patients may benefit from the cranio-cervical fixation. We present a case report of a patient with BI secondary to clivus hypoplasia who underwent cranio-cervical fixation in extension, with a reduction in clivus-canal angle and improvement of symptoms without posterior fossa decompression.
