RESUMO
OBJECTIVE: The aim of the study was to present our experience with the vertical musculocutaneous trapezius (VMCT) flap and highlight its utility in the thoracic wall reconstruction in patients with bronchopleural fistula (BPF). MATERIALS AND METHODS: We present a five case series of patients with long-standing cavities and BPF. The VMCT flap was used, and a direct pathway into the defect was made through a separate posterior thoracotomy shortening the distance between the flap and the defect. RESULTS: In 80% of the cases, the flap succeeded in solving the fistula and filling the defect, quality of life improved, and the need for oxygen decreased. CONCLUSIONS: Management of open window thoracostomy is challenging. Debridement, thoracoplasty, and flap coverage are the mainstream of their treatment, but these patients have scarce available muscle. The VMCT flap represents the major non-affected musculocutaneous unit in the thoracic area after lung surgery. Its dermal component offers a rigid matrix to form a seal over the bronchial stump. Its muscular component adds a good amount of vascularized tissue. No functional impairment has been described after its use.
OBJETIVO: Exponer nuestra experiencia con el colgajo vertical de trapecio y destacar su utilidad en la reconstrucción de la pared torácica en pacientes con fístulas broncopleurales. MATERIAL Y MÉTODOS: Presentamos una serie de cinco pacientes con cavidades y fístulas broncopleurales de larga evolución. Utilizamos el colgajo musculocutáneo vertical de Trapecio, con un redireccionamiento del mismo a través de una ventana costal que permite acortar la distancia entre el colgajo y el defecto. RESULTADOS: La fístula y el defecto fueron solucionados en el 80% de los casos. La calidad de vida mejoró y las necesidades de oxígeno disminuyeron. CONCLUSIONES: El manejo de las toracotomías es un reto. El desbridamiento, toracoplastia y cobertura con colgajo son los pilares de su tratamiento, pero estos pacientes tienen escasa disponibilidad muscular. El colgajo musculocutáneo vertical de Trapecio representa la mayor unidad intacta musculocutánea en el tórax tras cirugía pulmonar. Su componente dérmico ofrece una matriz rígida para sellar el muñón bronquial, su componente muscular añade una gran cantidad de tejido vascularizado. No se han descrito déficits funcionales tras su uso.

Bovine genital campylobacteriosis (BGC) is a leading cause of return to estrus in cows. The etiologic agent, Campylobacter fetus subsp. venerealis (Cfv) is transmitted by venereal route. Hence, the surrounding reproductive tract microenvironment could play a role in return to estrus in cows. The presence of Cfv in cervicovaginal mucus of Angus breed females provide three experimental groups, which were subject to bacteriome analyses: 10 Cfv-positive cows (CVP), 10 Cfv-negative cows (CVN), and 10 nonsexually active heifers (NSA). Cows with return to estrus showed higher bacterial richness than NSA. Beta diversity analysis showed a significant difference (P = 0.006) in bacterial composition among the three groups analyzed (CVP, CVN, and NSA). However, no significant difference was found when comparing the CVP versus CVN groups. Ureaplasma and Pseudomonas were the genera most frequently observed in NSA, being Ureaplasma the predictor genus to that group, whereas Alistipes, Bacteroides, Rikenellaceae_RC9_gut_group, UCG-005, and UCG-10 were both significantly more abundant and predictors genera in cows with return to estrus. Our results provide an overview of the cervicovaginal bacterial microbiota in cows harboring Cfv and improve the knowledge of the pathogenesis of BGC.

Abstract Tranexamic acid (TXA) significantly reduces blood loss in a wide range of surgical procedures and improves survival rates in obstetric and trauma patients with severe bleeding. Although it mainly acts as a fibrinolysis inhibitor, it also has an anti-inflammatory effect, and may help attenuate the systemic inflammatory response syndrome found in some cardiac surgery patients. However, the administration of high doses of TXA has been associated with seizures and other adverse effects that increase the cost of care, and the administration of TXA to reduce perioperative bleeding needs to be standardized. Tranexamic acid is generally well tolerated, and most adverse reactions are considered mild or moderate. Severe events are rare in clinical trials, and literature reviews have shown tranexamic acid to be safe in several different surgical procedures. However, after many years of experience with TXA in various fields, such as orthopedic surgery, clinicians are now querying whether the dosage, route and interval of administration currently used and the methods used to control and analyze the antifibrinolytic mechanism of TXA are really optimal. These issues need to be evaluated and reviewed using the latest evidence to improve the safety and effectiveness of TXA in treating intracranial hemorrhage and bleeding in procedures such as liver transplantation, and cardiac, trauma and obstetric surgery.

Liver lipidosis is a metabolic disorder mostly observed in high yielding dairy cattle, especially during the transition period. The aim of this study was to determine the correlation between hepatic lipid infiltration, biochemical indicators of liver function, and body condition score (BCS) variation in dairy cows. Fifty-one multiparous Holstein cows raised in a confined system were evaluated. Liver biopsies and blood samples were collected, and BCS was measured on days 3 and 28 postpartum. Lipid infiltration was determined by histologic examination. The plasma activity of aspartate aminotransferase, alkaline phosphatase, and gamma-glutamyl transferase and concentration of beta-hydroxybutyrate, non-esterified fatty acids, albumin, total bilirubin, and cholesterol were determined. BCS was measured using objective (camera) and subjective (visual) methods. Mild lipid infiltration was found in 3.92% of cows sampled on day 3 and 5.88% on day 28. Bilirubin was significantly higher on day 3 than on day 28 postpartum, and cholesterol was significantly higher on day 28 than on day 3 in all cows. There was no difference in biochemical analytes between cows with and without lipidosis. On day 3, mean subjective BCS was 3.10 and objective BCS was 3.16, while on day 28, these scores were 2.91 and 2.99, respectively. The calculated liver function index (LFI) was found to be a more sensitive indicator of liver function than the hepatic analytes evaluated. No correlation between BCS variation and lipid infiltration was found. Cholesterol and bilirubin levels showed the most remarkable changes during the early postpartum period. LFI is a potential indicator of postpartum liver function.
A lipidose hepática é um distúrbio metabólico principalmente observado nos bovinos de leite de alto rendimento, especialmente no período de transição. O objetivo deste estudo foi determinar a correlação entre infiltração lipídica hepática, indicadores bioquímicos de função hepática e variação da condição corporal em bovinos leiteiros. Foram avaliadas cinquenta e um vacas multíparas de raça Holandesa em confinamento. Coletaram-se biopsias de fígado e amostras de sangue, e a condição corporal (BCS) aferiu-se nos dias 3 e 28 pós-parto. A infiltração lipídica determinou-se mediante avaliação histológica. Mensuraram-se a atividade da aspartato aminotransferase, fosfatase alcalina e da gama-glutamil transferase, concentração de beta-hidroxibutirato, ácidos graxos não esterificados, albumina, bilirrubina total e colesterol. A BCS mediu-se utilizando método objetivo (câmera) e subjetivo (visualmente). Observou-se discreta infiltração lipídica em 3,92% dos bovinos amostrados no dia 3 e 5,88% no dia 28. Em todos os bovinos a bilirrubina foi significativamente mais alta no dia 3 do que no dia 28 e o colesterol foi superior no dia 28 do que no dia 3. Não houve diferença nos analitos bioquímicos dos bovinos com e sem lipidose. No dia 3, a média subjetiva da BCS foi 3,10 e a objetiva 3,16, enquanto no dia 28, obtiveram-se valores de 2,91, e 2,99 respectivamente. O índice calculado de função hepática mostrou ser um indicador mais sensível da função hepática do que os analitos avaliados individualmente. Não houve correlação entre a variação do BCS e infiltração lipídica.

Background: Primary erythrocytosis is a rare myeloproliferative disorder in dogs and cats characterized by an autonomous proliferation of erythroid precursors in the bone marrow, with low to normal serum erythropoietin concentration, resulting in elevated red blood cell count, hematocrit and hemoglobin concentration. Clinical signs are associated with increased blood volume and viscosity, and may include erythema, hyperemic mucous membranes and neurological signs such as seizures and ataxia. In veterinary medicine, the diagnosis should be made by exclusion of secondary or relative causes, after complementary exams. This report aims to describe a case of primary erythrocytosis in a bitch. Case: A 4-year-old mixed-breed bitch was referred to the Veterinary Medical Teaching Hospital from UFRGS with 3 convulsive episodes related by the owner. A previous abdominal ultrasonography revealed splenomegaly and the electrocardiogram showed no abnormalities. No alterations were observed at the physical examination. The laboratorial blood tests demonstrated a persistent erythrocytosis, with high hematocrit, hemoglobin and red blood cells count, thrombocytopenia and neutropenia, and total plasmatic protein within the reference interval. The bone marrow cytology revealed reduced cellularity, normal myeloid:erythroid ratio, erythroid hyperplasia, mild myeloid hyperplasia and moderate myelofibrosis. The serum erythropoietin measurement was within the reference range, and the blood gas analysis detected a slight decrease in partial oxygen pressure. Therefore, no evidence of secondary conditions was observed and the diagnosis of primary erythrocytosis could be made. Discussion: Since there is no definitive method, the diagnosis of primary erythrocytosis could be based on the exclusion of all secondary and relative causes of erythrocytosis. The absence of clinical signs of dehydration and high serum albumin levels were findings that conduced for the exclusion of the relative form of the disturbance. The echocardiography and the abdominal ultrasonography ruled out any cardiopulmonary condition or kidney neoplasm, the most common causes of absolute secondary erythrocytosis. The persistently high hematocrit levels and red blood cell counts are significant for the suspicion of primary erythrocytosis, although thrombocytopenia and neutropenia are not commonly reported. The clinical signs of seizure were correlated with increased blood viscosity and reduced blood flow at the central nervous system. The blood gas analysis discarded the occurrence of systemic hypoxia, and the normal levels of erythropoietin gives higher evidence of the occurrence of an autonomous proliferation of the erythroid precursors within the bone marrow. The bone marrow cytology confirmed erythroid hyperplasia and the reduced cellularity that could be attributed to myelofibrosis. Myelofibrosis was described in humans with polycythemia vera, but there are no reports in veterinary, and this occurrence must be elucidated. An identical mutation in the JAK2 gene was observed in humans with polycythemia vera and dogs with primary erythrocytosis, and occurs in more than 50% of humans with myelofibrosis. Further investigations are necessary for veterinary medicine. In conclusion, the systematic approach of all organic systems and the assessment of complementary exams are necessary for the diagnostic of primary erythrocytosis in dogs. This condition should be considered in the differential diagnosis of any erythrocytosis, considering the guarded prognosis of this hematologic disorder.

Plasmodium parasites' invasion of their target cells is a complex, multi-step process involving many protein-protein interactions. Little is known about how complex the interaction with target cells is in Plasmodium vivax and few surface molecules related to reticulocytes' adhesion have been described to date. Natural selection, functional and structural analysis were carried out on the previously described vaccine candidate P. vivax merozoite surface protein 10 (PvMSP10) for evaluating its role during initial contact with target cells. It has been shown here that the recombinant carboxyl terminal region (rPvMSP10-C) bound to adult human reticulocytes but not to normocytes, as validated by two different protein-cell interaction assays. Particularly interesting was the fact that two 20-residue-long regions (388DKEECRCRANYMPDDSVDYF407 and 415KDCSKENGNCDVNAECSIDK434) were able to inhibit rPvMSP10-C binding to reticulocytes and rosette formation using enriched target cells. These peptides were derived from PvMSP10 epidermal growth factor (EGF)-like domains (precisely, from a well-defined electrostatic zone) and consisted of regions having the potential of being B- or T-cell epitopes. These findings provide evidence, for the first time, about the fragments governing PvMSP10 binding to its target cells, thus highlighting the importance of studying them for inclusion in a P. vivax antimalarial vaccine.

BACKGROUND AND AIM: Rabbits often experience skin diseases. The beneficial effects of plant extracts and essential oils are well known in other species, but the properties of these natural ingredients have not been evaluated in rabbits in vivo. The objective of the current study was to evaluate the effect of a topical, commercial solution made of essential oils, plant-extracted polyunsaturated fatty acids, and Vitamin E on rabbits suffering from skin problems. MATERIALS AND METHODS: Thirty New Zealand rabbits (no sex distinction) were included in this study, with an average weight of 2-3 kg. The rabbits were divided into two groups: The first group was treated with a topical solution made from natural ingredients, and the second was a control group. The rabbits' hair and skin conditions were evaluated on days 1, 14, 28, and 35 after treatment. Data were analyzed using a Kruskal-Wallis range test. RESULTS: Significant differences were determined in terms of glossy hair variability on days 28 and 35 (p≤0.0001). On days 14-35, hair loss was determined to have reduced (p=0.001), and flaking and odor improved in the treatment group, showing increased scores and significant differences (p=0.0001). By contrast, the control group showed stable overall skin and hair score and an increase in the dryness score. CONCLUSION: The topical application of essential oils and polyunsaturated fatty acids with Vitamin E was able to improve hair shine and skin hydration and reduce flaking, bad odor, and hair loss, improving the general, and cutaneous aspect of rabbits.

Lice are ectoparasites capable of affecting birds, and can result in direct and indirect damage to their host. Afoxolaner is an isoxazoline that has been shown to be effective against these ectoparasites without known adverse effects. The objective of this research was to evaluate the effect of afoxolaner on lice in pheasants and plain chachalacas. A total of 29 pheasants of different genera and species (Chrysolophus pictus, C. amherstiae, Lophura swinghoii, L. nycthemera, Phasianus colchicus, and Syrmaticus reevesii) and 18 West Mexican Chachalacas (Ortalis poliocephala) naturally infested with Goniodes pavonis were used. The birds were allocated to one of two groups: group 1 treated with 2.50â¯mg/kg of afoxolaner, and group 2 given no treatment. Ectoparasites were collected using the adhesive tape technique and identified. Afoxolaner was administered later as a single dose to group 1, and the clinical assessment to detect ectoparasites was repeated 28 days post-treatment. On day 28 post-treatment, group 1 was found to be negative for the presence of lice. The body weights were compared at the beginning and end of the clinical assessment in both groups and a significant difference in weight of treated birds was found. The mean body weight decreased by 0.017â¯g in control group, whereas it increased by 0.016â¯g in treated group. Oral administration of afoxolaner is an effective option for the treatment of Goniodes pavonis infestations in zoo birds.

The wheat flour tortilla (WFT) is a Mexican food product widely consumed in the world, despite lacking fiber and micronutrients. Ramón seed flour (RSF) is an underutilized natural resource rich in fiber, minerals and bioactive compounds that can be used to improve properties of starchy foods, such as WFT. The study evaluated the impact of partial replacement of wheat flour with RSF on the physicochemical, sensory, rheological and nutritional properties and antioxidant capacity (AC) of RSF-containing flour tortilla (RFT). Results indicated that RFT (25% RSF) had higher dietary fiber (4.5 times) and mineral (8.8%; potassium 42.8%, copper 33%) content than WFT. Two sensory attributes were significantly different between RTF and WFT, color intensity and rollability. RFT was soft and it was accepted by the consumer. Phenolic compounds (PC) and AC were higher in RFT (11.7 times, 33%-50%, respectively) than WFT. PC identification by ultra-performance liquid chromatography quadrupole time of flight mass spectrometry (UPLC-QTOF-MS) showed that phenolic acids esterified with quinic acid, such as chlorogenic and other caffeoyl and coumaroyl derivatives were the major PC identified in RSF, resveratrol was also detected. These results show that RSF can be used as an ingredient to improve nutritional and antioxidant properties of traditional foods, such as the WFT.
RESUMO
RESUMEN El hiperadrenocorticismo (HAC) es una de las endocrinopatías más frecuentes en caninos, producida por la síntesis excesiva de cortisol. El HAC atípico u oculto es un síndrome caracterizado por la presentación de alteraciones clínicas, bioquímicas e imagenológicas compatibles con hipercortisolismo, pero con resultados normales en las pruebas endocrinológicas utilizadas convencionalmente para diagnóstico de HAC. Sin embargo, estos pacientes presentan elevada concentración sérica de precursores u otras hormonas corticoadrenales. El presente estudio describe el caso de una canina hembra, Bichón Frisé de 8 años de edad, epiléptica y tratada con fenobarbital, presentando signos clínicos asociados a HAC, en la que el test de supresión con dexametasona a dosis bajas y de estimulación con ACTH arrojaron valores normales. La medición de esteroides adrenales, post estimulación con ACTH, mostró elevación anormal de estrógenos y progesterona, persistiendo esta última después de que la paciente fuera esterilizada. El tratamiento con trilostano permitió la disminución de los niveles de progesterona y la resolución parcial de los signos clínicos. Sin em bargo, la recuperación clínica en su totalidad sólo se obtuvo después del diagnóstico y tratamiento del hipotiroidismo concomitante. El desafio que representa el diagnóstico del HAC atípico resalta la importância de realizar y disponer de paneles que incluyan medición de hormonas esteroideas adrenales diferentes al cortisol, además de considerar la ocurrencia de otras enfermedades endocrinas metabólicas concomitantes.
ABSTRACT Hyperadrenocorticism (HAC) is one of the most common endocrinopathies in dogs, caused by excessive synthesis of cortisol. Atypical or occult HAC is a syndrome characterized by the presentation of clinical, biochemical, and imaging alterations compatible with hypercortisolism, but normal results in endocrine tests that are conventionally used for HAC diagnosis. However, these patients present high serum concentrations of precursors or other corticoadrenal hormones. The present study describes the case of an 8 years old female canine, Bichón Frisé, epileptic and treated with phenobarbital, presenting clinical signs associated with HAC, in which the low-dose dexamethasone suppression test and stimulation with ACTH resulted within normal values. The measurement of adrenal steroids, after ACTH stimulation, showed abnormal elevation of estrogen and progesterone, the latter persisting after the patient was spayed. Treatment with trilostane allowed the reduction of progesterone levels and the partial resolution of clinical signs. However, full clinical recovery was only achieved after the diagnosis and treatment of concomitant hypothyroidism. The challenge that represent the diagnosis of atypical HAC highlights the importance of performing and having availability of panels that include measurement of adrenal steroid hormones other than cortisol, as well as considering the occurrence of other concomitant endocrine metabolic diseases.

La muestra fue no probabilística intencional, se dividió en 2 grupos: grupo A, a quienes se les administró antibioticoterapia profiláctica, y un grupo B, a quienes no se les administró antibiótico.Resultados : Se incluyeron 49 pacientes sometidos a cirugías electivas limpias de tipo colecistectomías (14/28.57%), herniorrafía umbilical (6/12.24%) y hernioplastia inguinal (29/59.18%). La edad promedio fue de 37,7±12,17 años. Predomino el sexo masculino. Al quinto día del postoperatorio no se observaron signos de complicación infecciosa en los grupos A y B. Al décimo día de postoperatorio se observaron signos de complicación infecciosa en un paciente (4.3%) perteneciente al grupo A. No se observó complicación infecciosa en el grupo sin administración de antibiótico, grupo B.Conclusión : La indicación y mantenimiento por 7-10 días de antibiótico profiláctico en cirugía limpia no presenta diferencia en la presentación de complicaciones infecciosas comparado con la no administración de antibióticos para este tipo de cirugía, con el riesgo potencial de producción de efectos adversos y desarrollo de resistencia bacteriana(AU)
The indiscriminate use of antibiotics and their mishandling by medical personnel is a frequent problem worldwide, which has increased bacterial resistance, treatment costs and the need for new antibiotics, often more expensive and of greater toxicity.Objective : to evaluate the use of prophylactic antibiotics in patients undergoing clean elective surgeries, in private centers in the Aragua state, in the period between February and August of 2019.Methods : we conducted a prospective, longitudinal, observational, analytical epidemiological clinical study. The participants consisted of non-probabilistic sample of the intentional type of 49 patients of the total study population, undergoing elective surgery, cholecystectomy (14 / 28.57%), umbilical herniorrhaphy (6 / 12.24%) and inguinal hernioplasty (29 /59.18%). The sample was classified into 2 groups, a group A, who received prophylactic antibiotic therapy and a group B, who did not receive it.Results : the mean age was 37.7 ± 12.17 years, predominantly male. On the fifth day of the postoperative period, no signs of infectious complication were observed neither in group A nor in group B. On the tenth day after the postoperative period, signs of infectious complication were observed in one patient (4.3%) belonging to the antibiotic administration group. No infectious complication was observed in the group without antibiotic administration.Conclusion : it was confirmed that the administration of antibiotics does not reduce the incidence of infection, when comparing an experimental group with a control group(AU)

The RBSA protein is encoded by a gene described in Plasmodium species having tropism for reticulocytes. Since this protein is antigenic in natural infections and can bind to target cells, it has been proposed as a potential candidate for an anti-Plasmodium vivax vaccine. However, genetic diversity (a challenge which must be overcome for ensuring fully effective vaccine design) has not been described at this locus. Likewise, the minimum regions mediating specific parasite-host interaction have not been determined. This is why the rbsa gene's evolutionary history is being here described, as well as the P. vivax rbsa (pvrbsa) genetic diversity and the specific regions mediating parasite adhesion to reticulocytes. Unlike what has previously been reported, rbsa was also present in several parasite species belonging to the monkey-malaria clade; paralogs were also found in Plasmodium parasites invading reticulocytes. The pvrbsa locus had less diversity than other merozoite surface proteins where natural selection and recombination were the main evolutionary forces involved in causing the observed polymorphism. The N-terminal end (PvRBSA-A) was conserved and under functional constraint; consequently, it was expressed as recombinant protein for binding assays. This protein fragment bound to reticulocytes whilst the C-terminus, included in recombinant PvRBSA-B (which was not under functional constraint), did not. Interestingly, two PvRBSA-A-derived peptides were able to inhibit protein binding to reticulocytes. Specific conserved and functionally important peptides within PvRBSA-A could thus be considered when designing a fully-effective vaccine against P. vivax.

Conclusión: Para las puérperas con MME su hospitalización en la Unidad de Cuidados Intensivos significo tener "temor a morir" y tener a su hijo(a) prematuro hospitalizado en la Unidad Neonatal significo "un milagro" porque es "hijo(a) de Dios".
Objective: Describe the significance conferred postpartum women with Maternal Near Miss about her hospitalization in the Intensive Care Unit and her premature child in the Neonatal Unit. Methodology: Qualitative study with ethnographic approach, using as a theoretical reference Madeleine Leininger through the Theory of Universality and Diversity of Cultural Care; the in-depth interviews and the qualitative analysis were carried out taking into account James Spradley's method. There were 21 in-depth interviews with 9 puerperal women with Maternal Near Miss who were hospitalized as well as their premature children in the ICU and NICU respectively of a clinic in the city of Sincelejo-Sucre, between March and December 2017. Results: 2 themes arise, the meanings of postpartum women with Near Miss Maternal Morbidity about their hospitalization includes 8 domains: knowledge of the warning signs, fear of dying, very difficult for my partner, postpone breastfeeding, back to the clinic, my family take care, the nurse takes care of me and learn from this experience; and the meanings about the hospitalization of the premature child conformed by 5 domains: the best moment of my life, the kangaroo, to care for the premature newborn, knowledge and education about the care of the premature and miracle of God. Conclusion: For the postpartum women with Maternal Near Miss, their hospitalization in the Intensive Care Unit meant having "fear of dying" and having their premature child hospitalized in the Neonatal Unit meant "a miracle" because it is "son of God"
