title: Serological occurrence for tick-borne agents in beef cattle in the Brazilian Pantanal

description: Abstract This study investigated the seropositivity for five different tick-borne agents, namely Anaplasma marginale, Babesia bovis, Babesia bigemina, Coxiella burnetii, Anaplasma phagocytophilum, and Trypanosoma vivax in beef cattle in the Brazilian Pantanal. The serum samples collected from animals (200 cows; 200 calves) were used in indirect enzyme-linked immunosorbent assays (iELISA) to detect IgG antibodies against A. marginale, B. bovis, B. bigemina, and T. vivax, and Indirect Fluorescent Antibody Test (IFAT) for detecting IgG antibodies against C. burnetii and A. phagocytophilum. No correlation was observed between seropositivity for C. burnetii and A. phagocytophilum with other agents whereas moderate correlation was observed for A. marginalexB. bigemina x B. bovis. Cows were more seropositive for T. vivax whereas calves were more seropositive for B. bovis and B. bigemina. The highest number of seropositive animals by a single agent was observed for T. vivax (15.2%). Co-seropositivity for T. vivax + A. marginale was higher in cows (25.5%) and for T. vivax + B. bovis + B. bigemina + A. marginale was higher in calves (57.5%). The high seropositivity correlation for A. marginale x B. bovis x B. bigemina is probably due to the presence of the tick biological vector, Rhipicephalus microplus, in the studied farms. Common transmission pathways, mediated by hematophagous dipterans and fomites, may explain the high co-seropositivity of cows for A. marginale and T. vivax. Low seropositivity to C. burnetii is probably due to the type of breeding system employed (extensive). Seropositivity for A. phagocytophilum in only one animal suggests the occurrence of a cross-serological reaction with another agent of the genus Anaplasma.

title: Biochemical predictors for metabolic syndrome in preterm infants according to weight ratio

description: ABSTRACT Objective Prematurity and low birth weight predispose preterm infants to cardiovascular disease in later life. Is the metabolic profile of these children impacted by the relation between birth weight and gestational age (GA)? This study aimed to evaluate whether the relationship between birth weight and GA of preterm infants has a positive correlation with the metabolic profile from birth to the sixth month of corrected age. Subjects and methods This is a longitudinal, prospective study with a cohort of 70 preterm and 54 term infants, who were enrolled in the study and shared into two groups: Appropriate for GA (AGA) and Small for GA (SGA), both classified at birth by Fenton and Kim curves. Longitudinal evaluation of anthropometry measures and blood samples of total cholesterol, glucose, triglycerides, and insulin were collected at birth, NICU discharge, and the sixth month of corrected age. Data were analyzed using descriptive and inferential statistical analysis (ANOVA, Fisher test, Shapiro-Wilk, and Cochran test). The effect size was 0.15, power was 0.92, and confidence interval 95%. Results No significant statistical differences were observed in relation to biochemical tests between AGA and SGA groups. However, a significant increase in triglyceride results above the reference values for age in the SGA group was observed throughout the follow-up. Conclusions Changes observed in the preterm infant metabolic profile show no correlation with adequacy of birth weight. Preterm lipid profile requires continuous evaluation at follow-up, due to the increased cardiovascular risk in later life.

title: [Ultrastructure and sperm cryopreservation of the amazon catfish (Leiarius marmoratus) in captivity]

description: ABSTRACT The aims of this study were to describe the spermatozoon ultrastructure and to evaluate the sperm cryopreservation of the amazon catfish with three cryoprotectant agents (10% methanol, 10% DMSO, and 10% ethylene glycol) and two activator agents (0.29% NaCl and 1% NaHCO3). Glucose 5% extender was used as a diluent solution and sperm loaded in 0.25 straws was frozen in nitrogen vapor (dry shipper). Fresh spermatozoon was 25.46±2.54μm long, the head was spherical (1.51±0.18μm) with no acrosome, the midpiece was cone shaped (0.93±0.17μm) with presence of vesicles, slightly asymmetric, and the flagellum was single (21.48±2.45μm). Post-thawed semen presented higher values (P&lt; 0.05) for duration, vigor and sperm motility rate with cryoprotectants 10% methanol and 10% DMSO. The duration of sperm motility was longer (P&lt; 0,05) when triggered in 1% NaHCO3 (96-21 s). Leiarius marmoratus semen cryopreserved with DMSO and methanol, presented respectively 7.32±4.21% and 8.94±6.69% of motility. However, the results were not satisfactory to establish a protocol for the specie.

title: Total reversal of internal carotid blood flow in a patient with severe stenosis of the brachiocephalic trunk

description: ABSTRACT Occlusions and severe stenoses of the innominate artery (brachiocephalic trunk) are rare and present with a wide variety of clinical manifestations, with hemispheric, vertebrobasilar and right upper limb ischemic symptoms. The most common cause is atherosclerosis. Duplex scanning may show right vertebral artery flow reversal, diminished subclavian flow, and several patterns of right carotid flow disturbance, including slow flow, partial flow reversal during the cardiac cycle and even complete reversal of flow in the internal carotid artery, which is a very uncommon finding. Herein, the authors describe the case of a female patient who was a heavy smoker, had severe stenosis of the brachiocephalic trunk, and had episodes of collapse. Besides the subclavian steal and partial flow reversal in the common carotid artery, duplex scanning also showed high-velocity reversed flow in the internal carotid artery during the entire cardiac cycle, a finding that is not reported in the literature at this magnitude.

title: Central and peripheral blood pressures and arterial stiffness increase in hypoparathyroidism

description: ABSTRACT Objective The aim of the present study was to evaluate whether arterial stiffness is affected in the patients with hypoparathyroidism through pulse wave analysis (PWA). Subjects and methods Sixty-three patients diagnosed with hypoparathyroidism and sixty volunteers were evaluated for the study. When 21 patients were excluded in the hypoparathyroidism group due to exclusion criteria, the research continued with 42 patients and 60 volunteers who are similar to the patients in terms of age, gender and body mass index (BMI). Fasting plasma glucose after 10 hours of fasting, creatinine, thyroid stimulating hormone (TSH), free thyroxine (fT4), albumin, calcium, phosphorus, magnesium, 25-OH vitamin D, parathormone (PTH) and urine calcium results in 24-hour urine for the patients in the hypoparathyroidism group were recorded. Evaluation of arterial stiffness was performed by Mobil-O-Graph 24h PWA device. Results Systolic blood pressure (SBP) (p = 0.01), diastolic blood pressure (DBP) (p = 0.005), mean blood pressure (p = 0.009), central SBP (p = 0.004), central DBP (p = 0.01) and pulse wave velocity (PWV) (p = 0.02) were found higher in the hypoparathyroidism group. A positive correlation was detected between phosphorus level and SBP [(p = 0.03. r = 0.327)], central SBP [(p = 0.04, r = 0.324)] and PWV [(p = 0.003, r = 0.449)]. We detected that age and serum phosphorus levels were independent predictor variables for PWV (B = 0.014, p &lt; 0.001 and B = 0.035, p &lt; 0.001, respectively). Conclusion We detected that hypoparathyroidism causes an increase in blood pressure and arterial stiffness. The most significant determinant factors were detected as advanced age and hyperphosphatemia. The patients diagnosed with hypoparathyroidism should be closely monitored and treatment planning should include to prevent the patients from hyperphosphatemia.

title: Acute aortic wall injury caused by aortic cross-clamping: morphological and biomechanical study of the aorta in a swine model of three aortic surgery approaches

description: Abstract Background Aortic cross-clamping and balloon occlusion of the aorta could lead to damage to the aorta wall. Objective The aim of this study was to investigate changes to the aorta wall related to the method used to interrupt flow (clamping or balloon) in the different techniques available for aortic surgery. Methods Experiments were performed on 40 female pigs, weighing 25-30kg, which were randomly allocated to 4 study groups: S (n=10), no intervention (sham group); C (n=10), midline transperitoneal laparotomy for infrarenal abdominal aortic access with 60 min of cross-clamping; L (n=10), laparoscopic infrarenal abdominal aortic surgery with 60 min of cross-clamping; EV (n=10), remote proximal aortic control with transfemoral arterial insertion of aortic occlusion balloon catheter, inflated to provide continued aortic occlusion for 60min. After euthanasia, the aortas were removed and cross-sectioned to obtain histological specimens for light microscopic and morphometric analyses. The remaining longitudinal segments were stretched to rupture and mechanical parameters were determined. Results We observed a reduction in the yield point of the abdominal aorta, decrease in stiffness and in failure load in the aortic cross-clamping groups (C and L) compared with the EV group. Conclusions Aortic cross-clamping during open or laparoscopic surgery can affect the mechanical properties of the aorta leading to decrease in resistance of the aorta wall, without structural changes in aorta wall histology.

title: Endovascular treatment of portal hypertension and recurrent digestive hemorrhage secondary to arterioportal fistula syndrome: late complication of penetrating abdominal trauma

description: Abstract The arterioportal fistula (APF) syndrome is a rare and reversible cause of pre-sinusoidal portal hypertension, caused by communication between a visceral artery and the portal venous system. Most patients are asymptomatic, but when they do develop symptoms, these are mainly related to gastrointestinal bleeding, ascites, congestive heart failure, and diarrhea. This therapeutic challenge presents a case of APF caused by a 20-year-old stabbing injury with unfavorable late clinical evolution, including significant malnutrition and severe digestive hemorrhages. The patient was treated using an endovascular procedure to occlude of the fistula.

title: Ultrasound-guided foam sclerotherapy for chronic venous disease with ulcer. A prospective multiple outcome cohort study

description: Abstract Background Chronic Venous Disease (CVD) is the main cause of chronic leg ulcers. Varicose veins are the most frequent cause of venous leg ulcers (VLU). 50.9% of Brazilian women have varicose veins and ulcer prevalence is as high as 4%. Ultrasound-guided foam sclerotherapy (UGFS) is a low-cost treatment option for varicose veins. Objectives To analyze UGFS outcomes in patients with VLU. Methods Prospective consecutive single center cohort study. Patients with great saphenous vein (GSV) reflux and VLU were treated and followed-up for 180 days. The following were studied: quality of life (QoL), disease severity, healing, and elimination of GSV reflux. The Aberdeen questionnaire, a venous clinical severity score, and Duplex scanning (DS) results were analyzed. Results 22 patients aged 35 to 70 years were treated. There was improvement in quality of life, disease severity reduced, and ulcer diameter reduced (p &lt; 0.001; ANOVA). 77.27% of VLU healed completely (95%CI: 59.76-94.78%). The dimensions of 20/22 VLU reduced (90.91%; 95%CI: 78.9-100%). GSV reflux was eliminated in 63.64% (95%CI: 43.54-83.74%). Men had greater QoL benefit and women had more complications. There were no severe complications. The VLU that had healed completely at the end of the study were smaller at baseline than those that did not completely heal. The GSV that were completely occluded at the end of the study were smaller at baseline than those that were not completely occluded (p &lt; 0.05; Mann-Whitney). Conclusion The results suggest that most patients benefited from UGFS.

title: Thermal and acoustical performance of building systems: study of tools that assist NBR15,575/2013 Brazilian building standard compliance assessment

description: ABSTRACT The Brazilian performance building code (NBR 15,575) addresses some requirements to assess the residential sector. However, setting a construction system option that meets this code has proven to be challenging. This study aims to evaluate the thermal and the acoustic performance of a social housing envelope, situated in Contagem-MG (Brazil), according to the minimal limits set by NBR 15,575. Structural masonry of ceramic blocks was selected for vertical sealing as well as concrete (floor-pavement) slab and ceramic tile, for horizontal closure. The NBR 15,575 simplified method was carried out for thermal analyzes whereas acoustic evaluation applied standard calculation and simulation method using Projetus software. Results indicated that the external walls need a thermal capacity improvement and the living room inner wall, which splits both unit apartments, need to increase its sound reduction index (Rw). Therefore, 2.5cm of plaster in both sides of wall should solve those problems. After this change proposition, the thermal and acoustic minimal performance standard were achieved. A small variation could be notice between calculation (Rw) and simulation sound insulation results (DnT,w and D2m,nT,w). Projetus is perfectly suitable for preliminary studies. As a conclusion, thermal and acoustic building system assessment in an early stage show to be relevant to foster its compliances adjustments as occurred e.g. in this study. Otherwise, major interventions may be necessary either at building site or after construction ends.
