Full textAbstract:
Equine metabolic syndrome (EMS) is a term adopted in 2002 in aim to define the complex pathology involving obesity, insulin resistance and laminitis in horses and ponies. The EMS was terminologically derived upon similar condition in humans. The metabolic disturbance in equines is developed sequentially to the primary chronic overfeeding, i.e. intake of surplus food to individual needs combined with insufficient activity of animal. The syndrome has been reported more frequently in ponies than in other breeds although genetic background of EMS has not been confirmed. The characteristic symptoms include regional collection of adipose tissue under the skin often distributed regionally i.e. in crest (neck from pool to withers), behind the shoulders, at the dock of the tail and in prepuce in males or in the udder in mares; as well as impaired locomotion and/or lameness in all four limbs and cycling disturbance in mares.

Full textAbstract:
Advancement in veterinary imaging technologies to assess pathology in the horses has been greatly improved since the development of computed tomography in the 1970s. These technical innovations have enabled faster acquisition times, lower patient doses of radiation and easier care of the patient during scanning. A wide range of computed tomography scanners are now available to the veterinary market, from companies providing second hand refurbished scanners, to those tailoring computed tomography scanners to the veterinary market. In turn, this makes the price of purchase, or rental, much more feasible to the industry. The financial implications of purchasing a scanner need to be reviewed to ensure viability, as well as identifying maintenance costs, space, specialist staffing and case load. However, even with access to advanced imaging devices such as computed tomography, imaging the equine patient comes with its own complexities and limitations. Owing to their size and anatomy, passing the relevant structures through the gantry can be difficult in itself, often requiring the administration of general anaesthetic to acquire suitable images, which comes with its own set of risks and additional costs. Therefore, there is an ongoing need to further develop the skills and abilities needed for standing computed tomography.

Full textAbstract:
There is an urgent need for detection of viral respiratory pathogens to identify the causal agent(s) involved and to prevent the spread of related diseases. The first part of this dissertation focuses on development, optimization and validation of Real-time reverse transcription polymerase chain reaction (rRT-PCR) assays for the detection of several common equine viral pathogens: equine arteritis virus (EAV), equine influenza virus and equine rhinitis viruses A and B. Emphasis of the second part of this dissertation is on studying the role of EAV envelope proteins in virus attachment and entry. Using an infectious cDNA clone of EAV and reverse genetics, a panel of chimeric viruses was generated by swapping the N-terminal ectodomains and full-lengths of the two major envelope proteins (GP5 and M) from porcine reproductive and respiratory syndrome virus (PRRSV). The recombinant viruses expressing the N-terminal ectodomain of PRRSV GP5 or M or both (GP5ecto, Mecto, and GP5&Mecto, respectively) in an EAV backbone were viable and genetically stable. Compared to the parental virus, these three chimeric viruses produced lower titers and smaller plaque sizes indicating that they have a crippled phenotype. Interestingly, the three chimeric viruses could only infect EAV susceptible cell lines but not the PRRSV susceptible cell line. Therefore, the exchange of GP5 and/or M protein N-terminal ectodomains from PRRSV did not alter the cellular tropism of the chimeric viruses. We also investigated the role of one of the minor envelope proteins (E) of EAV in virus attachment and entry. The results showed that EAV infection of equine endothelial cells is heparin-dependent and the Cterminus of the E protein contains a putative heparin-binding domain. We generated a panel of arginine to glycine mutations in the conserved region of both the full-length EAV infectious cDNA clone and individual E protein expression vectors. The triple mutation R52,60,65G construct grew significantly slower and produced much smaller plaques. The double mutant R52,60G completely blocked the interaction between E protein and heparin. Taken together, these data indicated that E protein interacts with heparin to facilitate virus attachment and plays a major role in EAV infection.

Previous issue date: 2011-11-07In equine, the intersections between reproduction and genomics are numerous, however, little known about the genetic factors that acting on fertility. The conclusion of equine genome sequencing project, brings the oportunity to evaluate candidate genes and molecular biomarkers for specific reproductive characteristics. Based on this information, this PhD thesis aimed to develop genomic studies applied to equine reproduction. The first paper analyzed the expression of apoptotic-related genes (Bax, Bcl-2, survivin and p53) in equine cumulus-oocyte complex by qRT-PCR, comparing gene expression between morphologically distinct oocytes and cumulus cells during in vitro maturation. Results showed that survivin mRNA levels were higher (P<0.05) and p53 mRNA levels was lower (P<0.01) in oocytes compared to cumulus cells in morphologically healthy. On the other hand, expression of the Bax was significantly higher in morphologically healthy cumulus cells (P<0.02). The second paper analyzed a single nucleotide polymorphism (SNP) in the p53 gene, looking for associations with reproductive parameters in Thoroughbred mares. This is the first study demonstrating the Arginine/Proline SNP in equine exon 4 p53 gene. The heterozygous Arginine/Proline was found in 73.3% of Thoroughbreds compared to the homozygous Arg/Arg and Pro/Pro that was detected in 17.1% and 9.6% of mares, respectively. The Arginine/Proline genotype was significantly associated with abortion (P=0.02), while Proline/Proline mares had a lower probability of abortion (P<0.05). These results indicate that p53 may play a role in equine reproduction. The second paper analyzed a single nucleotide polymorphism (SNP) in the p53 gene, looking for associations with reproductive parameters in Thoroughbred mares. This is the first study demonstrating the Arginine/Proline SNP in equine exon 4 p53 gene. The heterozygous Arginine/Proline was found in 73.3% of Thoroughbreds compared to the homozygous Arg/Arg and Pro/Pro that was detected in 17.1% and 9.6% of mares, respectively. The Arginine/Proline genotype was significantly associated with abortion (P=0.02), while Proline/Proline mares had a lower probability of abortion (P<0.05). These results indicate that p53 may play a role in equine reproduction. The third article has determined the presence of circulating cell-free fetal DNA (ccffDNA) in pregnant mare s plasma, looking to develop a molecular test for the prenatal diagnosis of fetal sex determination using SRY gene amplification by PCR, reamplification by PCR (2nd-PCR) and real-time quantitative PCR (qPCR). This is the first report of ccffDNA in equine species. The molecular sexing test resulted in sensitivity of 72% and accuracy of 85% on the PCR. Using the 2nd-PCR and qPCR we obtained an increasing in the sexing sensitivity results (90.9%) and an accuracy of 95%. This study demonstrates for the first time the fetal sex determination in mares using ccffDNA. This PhD thesis resulted in the publication of three papers in international journals of reproduction and a patent application request. The results presented here collaborate to understand the equine reproductive biology, and indicate potential genetic markers to fertility parameters.
Em equinos, as intersecções entre a reprodução e a genômica são numerosas, no entanto, pouco se sabe sobre os fatores genéticos que atuam na fertilidade. Com o genoma equino completo, existe a possibilidade de análises moleculares e estudo de genes candidatos a biomarcadores para características reprodutivas específicas. Com base nestas informações, a presente tese teve como objetivo desenvolver estudos de genômica aplicada à reprodução equina. O primeiro artigo analisou a expressão de genes relacionados a apoptose (Bax, Bcl-2, survivin e p53) no complexo cumulus oócito equino através de qRT-PCR, comparando a expressão gênica entre oócitos e células do cumulus com diferentes características morfológicas durante a maturação in vitro. Como resultados, foi observada maior expressão do survivin (P<0.05) e menor expressão de p53 (P<0.01) em oócitos comparado a células do cumulus do grupo considerado morfologicamente saudável. Enquanto que a expressão de Bax foi maior (P<0.02) em células do cumulus do grupo saudável comparado ao grupo com características morfológicas não desejáveis. O segundo artigo analisou um polimorfismo de nucleotídeo único (SNP) no gene p53, relacionando-o a parâmetros reprodutivos de éguas Puro Sangue Inglês. Foi relatado pela primeira vez um SNP Arginina/Prolina na região do exon 4 do gene p53 equino. A prevalência foi de 73,3% para o genótipo heterozigoto, 17,1% do genótipo Arginina/Arginina e 9,6% do Prolina/Prolina. O genótipo Arginina/Prolina foi associado (P=0.02) a ocorrência de aborto, enquanto que o genótipo Prolina/Prolina foi associado (P<0.05) a menor probabilidade de aborto, indicando um papel da p53 na reprodução equina. O terceiro artigo determinou a presença de DNA fetal livre e circulante (ccffDNA) no plasma de éguas prenhas, desenvolvendo um teste molecular de diagnóstico pré-natal na determinação do sexo fetal através da amplificação do gene SRY pelas técnicas de PCR, de re-amplificação por PCR (2º-PCR) e de PCR quantitativo em tempo real (qPCR). Este é o primeiro relato do DNA fetal livre e circulante em equinos. O teste de sexagem molecular resultou em 72% de sensibilidade e 85% de acurácia na técnica de PCR. Com o 2º-PCR e qPCR a sensibilidade foi de 90,9% e 95% de acurácia. Este estudo demonstra pela primeira vez a determinação do sexo fetal em éguas utilizando o ccffDNA. Os resultados apresentados colaboram para o entendimento da biologia reprodutiva da espécie equina, e indicam marcadores genéticos em potencial para parâmetros de fertilidade. Esta tese resultou na publicação de três artigos em periódicos internacionais da área de Reprodução e um pedido de Patente de Invenção.

A videotoracoscopia vem ganhando espaço na Cirurgia Veterinária, inclusive na espécie equina, dispondo de estudos que evidenciam resultados promissores no que se refere às suas aplicações diagnósticas e terapêuticas. Este trabalho teve por objetivo comparar dois tipos de endoscópios utilizados para videotoracoscopia em equinos em estação. Foram utilizados 9 equinos com idades que variaram entre 3 e 20 anos. Os procedimentos cirúrgicos foram realizados com os animais em estação, sob sedação, analgesia e anestesia local. Os equinos tiveram cada hemitórax, escolhido de forma aleatória, inspecionado com o endoscópio flexível e o endoscópio rígido (ângulo de visão de 0º, 33 cm de comprimento e 10 mm de diâmetro) através do 12º espaço intercostal. Ambos os endoscópios proporcionaram avaliação efetiva do hemitórax acessado, porém o flexível permitiu um mapeamento mais amplo da cavidade torácica do que o rígido, oportunizando a visualização de um número maior de estruturas, enquanto que rígido apresentou melhor luminosidade, definição de cor e imagem. O uso do endoscópio flexível permitiu a observação da porção ventral da cavidade torácica, assim como, a região cranioventral, permitindo a visualização de estruturas como a veia cava cranial e lobo acessório do pulmão direito. Não foram observadas complicações clínicas significativas com a utilização de ambos os endoscópios.Video thoracoscopy has been increasing in veterinary surgery, including the equine species, featuring studies have been showing promising results with regard to their diagnostic and therapeutic applications. This study aimed to compare two types of endoscopes used to perform thoracoscopy in standing horses. We used nine horses with ages ranging between 3 and 20 years. The surgical procedure was performed with the animals in standing, under sedation, analgesia and local anesthesia. The horses had each hemithorax, randomly chosen, inspected with the flexible endoscope and rigid endoscope (viewing angle of 0°, 33 cm long and 10 mm in diameter) through the 12th intercostal space. Both endoscopes have provided effective evaluation of the hemithorax accessed, but the flexible endoscope allowed a larger mapping of the chest cavity than the rigid, allowing the visualization of a greater number of structures, while the rigid endoscope showed better brightness, color definition and image. The use of flexible endoscope allowed observation of the ventral portion of the thoracic cavity and the cranio-ventral region, allowing visualization of structures such as the cranial vena cava and accessory lobe of the right lung. No significant clinically complications were observed with the use of both endoscopes.

Dissertação de Mestrado Integrado em Medicina VeterináriaA cólica, ou dor abdominal aguda, é um sinal inespecífico que pode ter origem em disfunções do tracto gastrointestinal ou outras que não envolvam o mesmo, sendo neste caso denominada “falsa cólica”. A cólica é responsável pelo maior número de mortes em equinos, à excepção de morte por idade avançada. A etiologia das doenças do tracto gastrointestinal dos equinos que levam à cólica é complexa e diversa. Ainda por explicar permanecem alguns deslocamentos intestinais ou torções e impactações. Na prática clínica diária a maioria dos casos de cólica tem causa desconhecida, mas em geral, resultam da distensão do intestino por ingesta, gás, fluidos ou devido a uma interrupção da motilidade normal do intestino (Íleo). Os casos mais severos podem também resultar de danos da parede intestinal por processos de isquémia, inflamação, edema ou enfarte. No diagnóstico desta afecção existem vários parâmetros que devem ser avaliados, tais como: grau de dor; distensão abdominal; frequência cardíaca, respiratória e características do pulso; coloração das membranas mucosas; tempo de repleção capilar; temperatura rectal; motilidade gastrointestinal; refluxo gástrico; achados à palpação rectal; hematócrito; concentração plasmática de proteínas totais; concentração plasmática de fibrinogénio; contagem de leucócitos; quantificação electrolítica; análise de gases sanguíneos; quantificação das enzimas séricas; concentração de lactato plasmático; características do fluido peritoneal recolhido por abdominocentése; achados ecográficos; achados radiográficos; achados à endoscopia; achados à laparoscopia; e análise fecal. O objectivo deste trabalho consistiu no estabelecimento de pontos orientadores na difícil decisão da terapêutica a adoptar na cólica equina, analisando os vários parâmetros de diagnóstico que, conjuntamente, permitem alcançar um diagnóstico mais preciso da afecção em causa e como tal, poder tomar-se uma decisão mais acertada quanto ao tratamento a seguir, seja ele médico ou cirúrgico. No estudo efectuado sobre 13 casos de cólica abdominal, verificou-se que os casos cirúrgicos foram acompanhados de uma dor mais violenta, e apresentaram frequências cardíacas e tempos de repleção capilar superiores aos dos pacientes que necessitaram apenas de tratamento médico, enquanto que a concentração plasmática de proteínas totais foi superior nos casos médicos. Dos resultados do estudo efectuado e de outros estudos já previamente existentes concluiu-se que quando existe um grau de dor severa, achados anormais à palpação rectal e ausência de resposta à terapêutica analgésica, deve-se referenciar o paciente para cirurgia, mesmo que a frequência cardíaca, coloração das membranas mucosas, tempo de repleção capilar, e análise do fluido peritoneal estejam dentro dos valores normais.
ABSTRACT The colic, or acute abdominal pain, is a non specific sign which can be originated by several disorders of the gastrointestinal tract or others that do not regard this last one, in which case the colic is named “false colic”. The true colic is responsible for the majority of deaths in horses, except those cases in which horses die due to advanced aging. The aetiology of the disorders of the gastrointestinal tract that lead to equine colic is complex and diverse. Still, with no explanation remain some gut displacements or twists and impactions. In the practical daily clinic the majority of colic cases have an unknown cause, but in general, they are a result of gut distention by ingesta, gas, fluids or due to an interruption of the normal motility (Íleus). The most severe cases can also result from damages of the intestinal wall by processes of isquemia, inflammation, edema or infarction. In the diagnosis of this pathology there are several parameters that must be evaluated, such as: pain degree; abdominal distention; the respiratory, heart and pulse rate; mucous membranes; membrane refill time; rectal temperature; gastrointestinal motility; gastric reflux; findings in rectal examination; packed cell volume; total plasma protein value; plasma fibrinogen value; white blood cell count; electrolytic quantification; analysis of blood gases; quantification of serum enzymes; plasma lactate value; characteristics of the peritoneal fluid collected by abdominal paracentesis; ultrasonographic findings; radiographic findings; endoscopic findings; laparoscopic findings; and fecal analysis. The goal of this work consisted on the establishment of guiding points in the difficult decision of the appropriate treatment, analyzing some parameters of diagnosis that, jointly, supply tracks to reach a more specific diagnosis of the disorder which is causing the abdominal pain, and as such to be able to make the right decision regarding the necessary treatment, being either surgical or medical. The study, which was carried on 13 cases of abdominal colic, has shown that surgical cases had a more violent pain, and had presented a higher heart rate and membrane refill time than the patients who only needed medical treatment, whereas the total plasma protein value was higher in medical cases. From these results and other previously existing studies, one can conclude that when exists a severe degree of pain, abnormal findings in the rectal examination and absence of response to the analgesic therapy, the colic case must be referred for surgery, even thought there are no significant changes in the heart rate, mucous membrane, membrane refill time and in the analysis of the peritoneal fluid.

Bicudo, Cesar Fernanda. "RHODOCOCCUS EQUI IN THE FOAL – IMPROVING DIAGNOSTIC AND PREVENTION MEASURES." UKnowledge, 2018. https://uknowledge.uky.edu/gluck_etds/36.
Full textAbstract:
Although Rhodococcus equi (R. equi), previously known as Corynebacterium equi, was first isolated from pneumonic foals almost a century ago, it remains the most common cause of subacute or chronic granulomatous bronchopneumonia in foals. While the majority of foals exposed to R. equi develop a protective immune response (regressors), others exhibit a unique susceptibility to infection (progressors). The determinants for either outcome are not completely understood. Therefore, current diagnostic and preventive measures are suboptimal and require betterment. In light of this current need, we hypothesized that immunoglobulin G subisotype T [IgG(T)] against the virulence-associated protein A (VapA) of R. equi, and whole blood cytokine expression profile of foals predict the outcome of infection and can be used as diagnostic markers of clinical disease. Further, we hypothesized that the use of R. equi hyperimmune plasma (HIP) decreases severity of disease in naturally infected foals, playing an important role in disease prevention in the field. Lastly, we hypothesized that specific anti-Rhodococcus equi pili antibodies passively acquired by foals via colostrum after immunization of pregnant mares with a Rhodococcus equi pili-based candidate vaccine will confer protection against induced disease, and therefore have an immediate impact on R. equi pneumonia prophylaxis.
The objectives of this study were: (1) to describe the humoral immune response of progressor and regressor foals to R. equi following experimental challenge and natural infection, (2) to compare the cytokine and cell-marker expression profile in whole blood of progressor and regressor foals after challenge, (3) to evaluate the Vap-A specific IgG profile of a commercially available HIP product and its value as a prophylactic tool on an endemic farm, and (4) to evaluate the efficacy of a vaccine based on the Rhodococcus equi pili (Rpl).
Although the IgG(T) response of progressor foals after challenge or following natural infection tended to be more pronounced than that observed in regressor foals, its performance as a diagnostic test for predicting disease outcome was poor. Likewise, whole blood cell-marker and cytokine expression profiles of progressor and regressor foals were not significantly different, undermining its reliability as a diagnostic tool. Evaluation of the association of HIP VapA specific IgG profile and rhodococcal disease outcome in the field resulted in the conclusion that progressor foals received significantly less VapA specific IgG, suggesting that HIP may have provided some protection to regressor foals. Although HIP appeared to have provided some protection against clinical pneumonia, Rpl maternally-derived IgG failed to confer any advantage to foals born from vaccinated mares. The Rpl candidate vaccine failed to confer protection to foals after challenge, and did not decrease disease severity in comparison to a control group.
In summary, the results of this study do not support the use of VapA specific IgG(T) or whole blood cytokine expression profile as predictors of disease outcome. Further, our results suggest a positive effect of HIP on disease outcome. Lastly, the presence of systemic and local Rpl antibodies was not protective in foals.

Full textAbstract:
Recent studies have provided conflicting results in regards to equine intradermal skin testing and its use in defining causative antigens in IgE mediated diseases such as equine recurrent airway obstruction (RAO). This study was divided into two experiments. In the first experiment of this study, the hypothesis tested was normal horses would have minimal variability in the wheals formed by intradermal injection of positive control stimulants. This was evaluated by examining the repeatability of skin test wheals created by 5 concentrations of histamine, compound 48/80, and phaseolus vulgaris (PHA) within a normal horse and between 12 normal horses at 0.5 hours, 4 hours, and 24 hours post injection. Minimal variability was detected within individual horses and between 12 horses for histamine and compound 48/80 at 0.5 hours and for PHA at 4 hours. This information suggests that the intradermal injection of positive control substances is a repeatable test in normal horses.
In the second experiment of this study, the hypothesis tested was normal horses react differently to intradermal injection of positive control stimulants (histamine, compound 48/80, PHA) and/or an environmental antigen (Aspergillus) in comparison to horses affected with RAO. This was evaluated by identifying differences in wheal responses between normal horses and RAO affected horses. Concentration response curves were created in normal and RAO affected horses to the aforementioned stimulants at 0.5 hours, 4 hours, and 24 hours post injection. No statistically significant differences were noted in concentration response between normal and ROA affected horses when compound 48/80 and PHA were evaluated. RAO affected horses demonstrated a greater slope at the 0.5 hour time when compared to normal horses suggesting that RAO affected horses are hypersensitive to intradermal injection of histamine. Injection of Aspergillus mix at 4000 protein nitrogen units/ml caused an intradermal wheal reaction at the 24-hour time in 4/5 RAO horses. This reaction was not noted in normal horses. This information suggests that there may be a positive relationship between causative antigens (i.e. Aspergillus) that may induce clinical RAO and positive intradermal skin test results.
An additional aspect that was evaluated in both experiments involved histologic examination of skin biopsies taken from wheals created by intadermal injection of histamine, compound 48/80, PHA, and Aspergillus at various times post injection. In the first experiment, intradermal injection of histamine caused severe dermal edema and margination of neutrophils and eosinophils at 0.5 hours. Compound 48/80 demonstrated mild to modest dermal edema at 0.5 hours while PHA demonstrated severe dermal edema, hemorrhage, and lymphactic ectasia at 4 and 24 hours. PHA also demonstrated a neutophilic inflammation at 4 hours that progressed to a mixed lymphohistiocytic and neutrophilic inflammation at 24 hours. In the second experiment, no edema and modest to moderate neutrophilic inflammation was noted in normal horses after intradermal injection of Aspergillus at 24 hours. In contrast, RAO affected horses demonstrated mild to modest edema and a mild to moderate mixed inflammatory response (lympho-histocytic, neutrophilic, eosinophilic) after intradermal injection of Aspergillus at 24 hours suggesting a delayed type response.Master of Science

Dissertação de Mestrado Integrado em Medicina VeterináriaA síndrome podotroclear corresponde à entidade clínica responsável pela claudicação, geralmente dos membros anteriores, associada a um processo doloroso com origem no osso navicular e/ou com as estruturas que com ele se relacionam. O seu diagnóstico resulta da conjugação da análise do exame estático, exame dinâmico, anestesias perineurais e intra-articulares e exames complementares de diagnóstico, tais como radiografia e ressonância magnética. O presente estudo tem como objetivo avaliar a importância clínica das alterações em bursografias de contraste. Para isso foi selecionada uma amostra de 10 cavalos com síndrome podotroclear nos quais se administrou um contraste iodado na bursa podotroclear e procedeu-se à realização de radiografias na projeção palmaroproximal-palmarodistal oblíqua. Dos 10 cavalos examinados, 9 apresentavam alterações na bursografia, podendo ser na fibrocartilagem, na face flexora do tendão digital profundo ou em ambas. Verificou-se que não há uma relação direta entre alterações radiográficas no osso navicular e as alterações encontradas na bursografia de contraste. Embora o tamanho a amostra não seja estatisticamente relevante, este estudo vem propor que a bursografia de contraste constitui um exame complementar de diagnóstico que pode fornecer informações pertinentes na avaliação de estruturas do aparelho podotroclear tais como a fibrocartilagem e a face flexora do tendão flexor digital profundo, podendo ter uma importância acrescida no diagnóstico de síndrome podotroclear quando meios como a ressonância magnética não estão disponíveis.
ABSTRACT - Preliminary study of contrast bursografias in horses with radiographic changes consistent with podotroclear syndrome - Navicular syndrome is the clinical condition that causes lameness, usualy in the forelimbs, associated with pain arising from the navicular bone and closely related structures. Diagnosis results from the combination of the visual examination at rest and at exercise, perineural anesthesia, intrasynovial anesthesia and the imaging procedures as radiology and magnetis resonance imaging. This study aims to evaluate the clinical significance of changes in contrast bursographs. With this purpose, was selected a sample of 10 horses with podothroclear syndrome in witch an iodinated contrast was administered in podotroclear bursa and proceeded to the accomplishment of the palmaroproximal-palmarodistal oblique radiographs. Of the 10 examined horses, 9 showed changes in bursography, that could be in the fibrocartilage, in the dorsal surface of the deep digital flexor tendon or both It was found that there is no direct relationship between radiographic changes in the navicular bone and the changes found in contrast bursographs. Although the population was not statistically significant, this study proposes that contrast bursography is a complementary diagnostic procedure that can provide relevant information in the assessment of the podothroclear apparatus structures such as fibrocartilage and the flexor surface of the deep digital flexor tendon and may have a greater importance in the diagnosis of navicular syndrome when imaging procedures such as magnetic resonance imaging are not available.

Full textAbstract:
Abstract The drive for capital efficiency in unconventionals has encouraged operators to understand subsurface interactions as effectively as possible. Combining multiple types of new and proven field technology systematically with advanced fracture modeling tools has led to continued improvements in field testing, understanding, and acreage development. Careful selection and application of these tools and technologies to understand subsurface characteristics and responses is a high priority when determining how to improve the net asset value. Diagnostic and modeling results will be integrated together to show how these learnings, when combined appropriately, equate to a sum greater than their parts. Several field case studies will be provided to illustrate the benefits of the multi-pronged diagnostics with modeling approach. Fiber optic strain monitoring and Sealed Wellbore Pressure Monitoring (SWPM) tests will be combined and performed across multiple wellbore distances with multiple fracture design tests. Results will then be analyzed to understand fracture growth characteristics by using a hydraulic fracture simulator capable of convective particle transport, multi-fracture stress and strain shadowing, and complex fluid rheology. Select results will then be coupled with concurrent diagnostics that include microseismic, formation imaging, and casing caliper data to show how hydraulic fracturing interactions occur dynamically in the subsurface. The geomechanics models will then be used to inform stage and cluster level details derived from field diagnostics that include stimulation and production performance behaviors, which incorporate combined non-Darcy and multi-phase flow impacts. Technologies will include erosion imaging diagnostics and permanent fiber optic warmback results. Finally, a cluster-level analysis with downhole fiber optics strain data will be analyzed in conjunction with SWPM to inform subsurface dynamics and show how fracture treatment design optimization may be achieved by combining field learnings with the modeling. These case studies are summarized to show how proper geomechanics modeling, application of field data, collection of the necessary diagnostics, and testing methods are used together to effectively improve completion designs, well spacing configurations, field diagnostics, and real-time stimulation and post-stimulation production analyses.

Context: In Brazil, schistosomal myelitis is the third most common cause of myelopathy. The diagnosis of neuroschistosomiasis is not easy to make. In a study published in 2001, the author proposed a classification for the diagnosis of schistosomal myelorradiculopathy: Proven Diagnosis; Probable Diagnosis and Possible Diagnosis. Case Reports: Case 1, admitted in 2021 with 40 days of paraparesis and ascending paraesthesia, urinary retention and severe low back pain. He had proximal and distal grade 1 paraparesis, eosinophilia at blood count, CSF with hyperproteinorrhachia, normal cellularity and indirect immunofluorescence (IFI) for reactive schistosomiasis, as well as stool parasitology (EPF) and spine MRI with hypersignal in the spinal cord. Case 2, admitted in 2020 with 20 days of constipation and urinary retention followed by paraparesis and ascending paresthesia and sexual impotence. He presented proximal and distal grade 3 paraparesis and CSF with protein-cytological dissociation. Both had abolished deep reflexes and hypoaesthesia with levels in L2 and T10, respectively. As a result of the other exams and MRI with hypersignal of D6 to medullary cone with contrast impregnation and cauda equina roots, despite case 2 having EPF and IFI for schistosomiasis in the CSF negative, for presenting positive epidemiology for schistosomiasis, both were treated with solumedrol for 5 days, praziquantel and oral prednisone, with improvement afterwards. Conclusion: The outcome of schistosomal myelitis is directly related to early diagnosis and treatment. It is necessary to value all clinical, laboratory and epidemiological findings in patients living in an endemic area.

Introdução: O acidente vascular encefálico (AVE) é uma causa importante de mortalidade e incapacidade no mundo. Uma das sequelas que devemos sempre nos atentar no paciente é a disfagia que é presente em mais de 40% dos pacientes com AVE. A disfagia é um marcador de mau prognostico e gera risco de pneumonia aspirativa por aspiração de saliva e/ou alimento, aumento do tempo de internação, aumento dos custos com serviços de saúde, incapacidade e dependência, assim gerando crescimento da mortalidade desses pacientes. Objetivo: O objetivo desse trabalho é analisar publicações científicas recentes referentes à disfagia no paciente com AVE, a fim de elucidar aspectos relacionados ao seu diagnóstico, manejo, tratamento e prevenção visto a importância do tema na morbidade e mortalidade do paciente. Materiais e métodos: Para a realização desta revisão bibliográfica a respeito da Disfagia no paciente com AVE foram feitas pesquisas nas bases de dados Scielo e Pubmed além de consultas a livros acadêmicos. A pesquisa envolveu artigos publicados nos idiomas inglês, português nos últimos 20 anos. Resultado: Alguns indícios que o paciente com AVE apresenta disfagia são perda de peso, Tosse, pigarro, regurgitação nasal, resíduos na cavidade oral e fala nasalizada. A videofluoroscopia é o padrão-ouro no diagnóstico da disfagia, porem nem sempre está disponível ou é apropriada a todos os pacientes com AVE na fase aguda. Devido a indisponibilidade da videofluoroscopia no nosso meio é realizado testes clínicos de rastreio principalmente pela fonoaudióloga. O paciente com AVE com diagnostico de disfagia tem que ser acompanhado por uma equipe multidisciplinar, sendo que a disfagia deve ser avaliada mais de uma vez, visto que a incidência de disfagia pode diminuir após a fase aguda da doença. Conclusão: é visível a importância de diagnóstico e manejo correto da disfagia em pacientes com AVE, sendo essencial a abordagem da equipe multidisciplinar para reabilitação destes pacientes e diminuição da morbidade e mortalidade.

Introdução: A Síndrome da Imunodeficiência Adquirida é uma doença causada pelo vírus HIV, que afeta o sistema imunológico, reduzindo o funcionamento do organismo e incapacitando-o de se defender contra doenças oportunistas. No Brasil, os Centros de Testagem e Aconselhamento (CTA) foram criados em resposta à epidemia do HIV/AIDS, oferecendo testagem e aconselhamento aos indivíduos. Atualmente, os CTA oferecem testagem e tratamento medicamentoso do HIV e outras Infecções Sexualmente Transmissíveis e ações de educação e aconselhamento para a redução de riscos e vulnerabilidades, assumindo papel estratégico no diagnostico precoce, prevenção combinada e educação em saúde. Em São José de Ribamar, o CTA iniciou em 2013 garantindo acesso especialmente para a população mais vulneráveis. Em 2020, o CTA precisou se readequar para ofertar atenção integral e de qualidade em meio aos desafios da COVID-19. Objetivo: Descrever a atuação do CTA de São José de Ribamar no ano de 2021. Material e métodos: Relato de experiência, sobre a vivência da equipe do CTA de São José de Ribamar, município da região metropolitana de São Luís, Maranhão, em 2021. Resultados: O CTA SJR acompanha 304 paciente, tanto de São José de Ribamar quanto de outros municípios da região metropolitana de São Luís. Quanto às ações realizadas, a equipe considerou o risco de contaminação pela COVID-19. O Maranhão iniciou 2021 com 200.938 casos e 4.500 óbitos por COVID-19. Portanto, utilizou-se ações programadas por outros serviços como Unidades Básicas de Saúde, Hospital Municipal, Secretaria de Saúde, Associação Comunitária e Comunidade Terapêutica para realizar suas ações. Ao longo do ano, foram 16 participações extramuros com educação em saúde voltadas à prevenção de IST, distribuição de preservativos e realização de testes rápidos. Ao final do ano, foram diagnosticados 15 novos casos de HIV e 45 novos pacientes cadastrados no serviço, a diferença se deu por casos indivíduos que buscaram o CTA após as ações extramuros. Conclusão: É importante que campanhas de prevenção e educação relacionadas a HIV/AIDS sejam ofertadas para todas as faixas etárias. Nessa perspectiva, a organização e mobilização do serviço é essencial pra a implementação intra e extramuros para o impacto no comportamento epidemiológico das IST no território.

No es nada nuevo que la salud es una prioridad y por consiguiente los equipos médicos, en la capital del Meta, Villavicencio; la oportunidad para la asignación de citas que requieren exámenes de Tomografía Axial Computarizada (TAC) cada vez es más difícil, esto debido a que en la ciudad se evidencia la existencia de 3 equipos TAC, y en ocasiones cuando alguno está en mantenimiento preventivo es tiempo valioso que se pierde, y en ocasiones sin programación alguna se presentan urgencias de mantenimiento correctivo y en ocasiones las partes o repuestos para su cambio se demoran en llegar, lo anterior hace que las agendas colapsen. En consecuencia, se debe tomar medidas de carácter urgente para realizar los diferentes exámenes que se pueden hacer con el TAC ya que estos equipos permiten por medio de imágenes diagnosticar el paciente, por tanto, se debe dar prioridad a los pacientes que requieren estos exámenes y se deben de enviar a otras ciudades incrementado los costos hospitalarios y poniendo en riesgo la vida por los traslados medicalizados. La clínica Angiografía de Colombia con sede en Villavicencio, ha identificado esta necesidad y dispone de espacio para su aprovechamiento y así para poner en funcionamiento un nuevo TAC; el sótano de la clínica donde se tiene previsto realizar las adecuaciones para este equipo funciona como parqueadero. Desde el área de conocimiento en Tecnología e ingeniería, este proyecto de investigación busca hacer el cálculo eléctrico para constatar si el transformador que tiene la clínica Angiografía de Colombia funciona para el equipo que deseen instalar, se debe hacer el cálculo de cargas del consumo actual y posterior al resultado se procede hacer el diseño eléctrico según el requerimiento técnico del equipo, adecuación de luminarias, tomacorrientes y sistema de respaldo donde se plantee instalar el equipo. La clínica fue construida en el año 2016 y la carga eléctrica está diseñada y dimensionada para los equipos que funcionan en la actualidad. La clínica Angiografía de Colombia requiere saber si el transformador que tienen desde su construcción soportaría la carga del equipo de Tomografía Axial Computarizada (TAC) que desean instalar o se debe de realizar un cambio en la subestación. Diseñar desde cero puede resultar sencillo, pues se tiene amplias opciones para modificar las condiciones durante el proceso; pero diseñar sobre algo ya construido limita las opciones. Para este caso tratar de implementar este nuevo equipo conlleva modificar el consumo energético de la clínica, además hay que considerar una normatividad vigente para la parte de la obra civil y la instalación eléctrica en centros médicos. Las adecuaciones al sistema eléctrico, al sistema de puesta a tierra junto con el sistema de respaldo de energía (UPS) y el transformador del edificio requieren una obtención de datos para hacer los cálculos, estos se tomarán previamente con un registrador de red para ver el balanceo de las fases, el factor de potencia, los armónicos, los picos de consumo, entre otros. Se espera que este diseño permita esta adecuación con la menor afectación al servicio.

Full textAbstract:
Abstract The Mariner Field consists of two shallow heavy oil reservoir sections: the deeper Maureen Formation and the shallower Heimdal Reservoir. Produced water is re-injected through stand-alone screens providing pressure maintenance for the aquifer support and producer well life longevity. The challenge is to design a drill-in fluid for the injectors to allow matrix injection across the sand face. This improves the longevity of the lower completion screens by reducing hot spot completion damage created by the injection fluid (Yildiz, 2004). It also improves the pressure support for the producing wells. Equinor is committed to using sustainable, environmentally sound drilling fluid options. Therefore, the preference was to utilize a water-based drilling fluid with the application of a breaker after the lower completion was in place. A significant formation damage study was performed using various designs of water-based fluids. Each formulation utilized a biopolymer to provide viscosity and rheological support. The sands were unconsolidated and sand packs had to be created to mimic the reservoir characteristics of the Maureen reservoir. This potentially impacted the formation damage interpretation. From the formation damage study, biopolymer was highlighted as a limiting damage mechanism. This prompted both Equinor and Schlumberger to look at alternative ways to provide rheological support without using biopolymers. A mono-valent biopolymer free reservoir drill-in fluid was designed specifically for this challenging high Darcy reservoir to mitigate the formation damage seen from coreflooding. This paper will detail the design, testing, diagnostic analysis of the formation damage mechanism and the new biopolymer free fluid. Together they showed a step change improvement in the formation damage testing. In addition, the paper will also detail the deployment of the new fluid on Mariner. Furthermore, it will describe how the laboratory design translated into large scale plant mixing with deployment at the rig site.

Introdução: Os medicamentos são utilizados com a finalidade de diagnosticar, prevenir, curar doenças ou amenizar seus sintomas, entretanto quando utilizado de maneira inadequada podem potencialmente causar danos à saúde. Estudos demonstram que em média são gastos oito milhões e trezentos mil com danos relacionados a medicamentos, sendo esses evitáveis. Segundo a OMS ocorre 2,6 milhões de mortes por ano em países de baixa e média renda e a sua maioria são óbitos evitáveis. Objetivo: Analisar as ações que são capazes de minimizar os danos relacionados a medicamentos em ambientes hospitalares. Material e métodos: Foi realizada uma revisão bibliográfica com busca de dados nas principais plataformas, compilando artigos disponíveis no Google acadêmico, Scielo e Revistas e Periódicos digitais. Resultados: Entre os artigos pesquisados as ações que mais mostrou-se satisfatórias para a redução de danos em serviços hospitalares é a implementação da dose unitária, da farmácia clínica e sistema computadorizado de prescrição, treinamento periódico de toda a equipe envolvida no sistema de medicação. Conclusão: a junção de todas as estratégias evitaria consideravelmente as falhas tais como de prescrições ou prescrições ilegíveis, falta de dados e informações relevantes na prescrição, interações medicamentosas, doses dobradas, medicamentos não administrados, entre outros o que acarretaria além da redução de mortes de pacientes por causa de erros de medicação a redução de gastos por causa desses referidos gastos.

Many students struggle with mathematics in late elementary school, particularly on the topic of fractions. In a best evidence syntheses of research on increasing achievement in elementary school mathematics, Pelligrini et al. (2018) highlighted tutoring as a way to help students. Online tutoring is attractive because costs may be lower and logistics easier than with face-to-face tutoring. Cignition developed an approach that combines online 1:1 tutoring with a fractions game, called FogStone Isle. The game provides students with additional learning opportunities and provides tutors with information that they can use to plan tutoring sessions. A randomized controlled trial investigated the research question: Do students who participate in online tutoring and a related mathematical game learn more about fractions than students who only have access to the game? Participants were 144 students from four schools, all serving low-income students with low prior mathematics achievement. In the Treatment condition, students received 20-25 minute tutoring sessions twice per week for an average of 18 sessions and also played the FogStone Isle game. In the Control condition, students had access to the game, but did not play it often. Control students did not receive tutoring. Students were randomly assigned to condition after being matched on pre-test scores. The same diagnostic assessment was used as a pre-test and as a post-test. The planned analysis looked for differences in gain scores ( post-test minus pre-test scores) between conditions. We conducted a t-test on the aggregate gain scores, comparing conditions; the results were statistically significant (t = 4.0545, df = 132.66, p-value < .001). To determine an effect size, we treated each site as a study in a meta-analysis. Using gain scores, the effect size was g=+.66. A more sophisticated treatment of the pooled standard deviation resulted in a corrected effect size of g=.46 with a 95% confidence interval of [+.23,+.70]. Students who received online tutoring and played the related Fog Stone Isle game learned more; our research found the approach to be efficacious. The Pelligrini et al. (2018) meta-analysis of elementary math tutoring programs found g = .26 and was based largely on face-to-face tutoring studies. Thus, this study compares favorably to prior research on face-to-face mathematics tutoring with elementary students. Limitations are discussed; in particular, this is an initial study of an intervention under development. Effects could increase or decrease as development continues and the program scales. Although this study was planned long before the current pandemic, results are particularly timely now that many students are at home under shelter-in-place orders due to COVID-19. The approach taken here is feasible for students at home, with tutors supporting them from a distance. It is also feasible in many other situations where equity could be addressed directly by supporting students via online tutors.
