ABSTRACT

Objetivo. Conhecer o processo de integração de Tecnologias Digitais de Informação e Comunicação (TDIC), facilidades e limites percebidos por docentes de um curso de graduação em Enfermagem. Metodologia. Estudo descritivo e exploratório, de abordagem qualitativa, realizado no ano de 2018, com nove docentes de um curso graduação de Enfermagem de uma universidade pública localizada no interior cearense. Para o processo de produção dos dados, foram realizadas entrevistas semiestruturadas e procedeu-se à análise de conteúdo. Resultados. As TDIC têm sido integradas às práticas docentes em diferentes perspectivas, em atividades teóricas e práticas, a partir do uso de aplicativos móveis de simulação de práticas, redes sociais, links para websites, grupos de WhatsApp® e vídeos-aulas. Ademais, a integração dessas tecnologias amplia a criação de estratégias que promovem a participação ativa do educando, oferecendo espaços de reflexão, autonomia, bem como o desenvolvimento da criatividade. Os docentes destacam a interatividade e comunicação, o acesso a recursos que não estão disponíveis na Universidade, como modelos anatômicos, manequins/simuladores de procedimentos de Enfermagem. Dentre os limites, as questões estruturais, de acesso à internet, ausência de políticas institucionais e educação permanente são fatores que demandam maior atenção para que aconteça uma efetiva integração pedagógica das TDIC. Conclusão. Embora represente um processo inicial, percebe-se um potencial para continuidade e expansão das TDIC em diferentes ambientes e disciplinas. Esforços têm sido empreendidos pelos docentes para integrar essas tecnologias ao contexto das atividades pedagógicas no curso de Enfermagem.


Objective. The objective of this study is to know the integration process of Digital Technologies of Information and Communication (DTIC), facilities and limits perceived by professors of an undergraduate course in Nursing. Methods. Descriptive and exploratory study, with a qualitative approach, carried out in 2018, with nine professors from an undergraduate Nursing course at a public university located in the interior of Ceará. For the data production process, semi-structured interviews were conducted and content analysis was carried out. Results. DTIC have been integrated into teaching practices from different perspectives, in theoretical and practical activities, using mobile practice simulation applications, social networks, links to websites, WhatsApp® groups and video-lessons. Furthermore, the integration of these technologies increases the creation of strategies that promote the active participation of the student, offering spaces for reflection, autonomy, as well as the development of creativity and collaboration. Teachers highlight interactivity and communication, access to resources that are not available at the University, such as anatomical models, simulators of nursing procedures. Among the limits, structural issues, access to the internet, absence of institutional policies and permanent education are factors that demand greater attention for an effective pedagogical integration of DTIC. Conclusion. Although it represents an initial process of use, there is a potential for continuity and expansion of DTIC in different environments and disciplines. Efforts have been undertaken by teachers to integrate these technologies into the context of pedagogical activities in the Nursing course.

ABSTRACT

Aim: This study aimed to evaluate the effect of frozen storage on the physical properties of a silicone-based test food material, highly used to evaluate the masticatory performance in research settings. Methods: A total of 1,666 silicone cubes of Optosil Comfort® with 5.6-mm edges were shaped and stored at -18°C. The cubes were subsequently tested for flexural strength (maximum force, displacement, stress, and strain) before breaking (n = 136), changes in weight and size (n = 170), and masticatory performance (n = 1360) at eight timepoints: immediately after cube preparation (baseline, no freezing), and 1, 2, 3 and 4 weeks, and 2, 4 and 6 months after frozen storage. The cubes were thawed 8 h before each assessment. Results: The maximum force, stress, maximum displacement, and deformation values for the cubes were not affected by freezing (P > 0.05). At all of the time points, the cubes exhibited similar weight (P = 0.366) and size (identical values). The masticatory performance for the cubes also showed no differences from baseline through 6 months (P = 0.061). Conclusion: Freezing Optosil Comfort® silicone cubes did not alter the physical and mechanical properties of the material, being suitable to optimize the assessment of masticatory parameters for research purposes

ABSTRACT

Objetivos: estabelecer diagnóstico diferencial das demências em ambulatório de geriatria no Distrito Federal, calculando-se sua prevalência por meio de exame clínico e avaliação multifuncional. Método: estudo longitudinal, retrospectivo, com amostra de pessoas com 60 anos ou mais residentes no Distrito Federal-Brasil, com déficit cognitivo caracterizado por Transtorno Neurocognitivo (TNC) Maior (demência), cadastradas durante os anos de 2010 a 2018. A coleta de dados foi realizada em prontuários para selecionar e avaliar o perfil do idoso com diagnóstico de TNC seguida de avaliação geriátrica ampla e avaliação multifuncional. A análise de dados foi realizada com o cálculo da prevalência, estatística descritiva e índice V de Cramer. Resultados: 158 indivíduos conseguiram concluir todas as avalições. 52,5% possuem de 80 a 89 anos, 62,5% são mulheres e 62,7% caucasianos, 50,6% viúvos e 47,5% analfabetos. A prevalência inicial de Doença de Alzheimer (DA) foi de 45,6%, reduzindo-se para 35,4% após um período de acompanhamento e a demência vascular (DV) foi de 34,2%, inicialmente, e 45,6% ao final. Utilizou-se o Coeficiente V de Cramer, em que se encontrou uma relação fraca de fatores de risco com os diagnósticos das demências apresentados. Conclusão: DV foi a mais prevalente na área estudada. Entende-se ser a maior frequência de DA esteja relacionada à avaliação superficial uma vez que esse tipo de demência é mundialmente mais frequente

ABSTRACT

Abstract Introduction: Most successful cases of COVID-19 pandemic mitigation and handling have relied on extensive reverse-transcription quantitative polymerase chain reaction (RT-qPCR). However, many emerging economies have struggled with current molecular testing demands due to economic, technical and technological constraints. Objective: To define a potential diagnostic protocol to increase testing capacity in current and post-pandemic conditions. Methods: We reviewed the literature, patents and commercial applications, for alternatives. Results: We found a good potential in saliva samples, viral inactivation and quick RNA extraction by heating; the use of an isothermal technology such as loop mediated isothermal amplification (LAMP) and naked eye test-result visualization by in-tube colorimetry or turbidity. Conclusions: Saliva samples with quick RNA extraction by heating and colorimetric LAMP are promising options for countries with economic and infrastructure limitations.


Resumen Introducción: La mayoría de los casos exitosos de mitigación y manejo de la pandemia de COVID-19 se han dado mediante pruebas basadas en la reacción en cadena de la polimerasa cuantitativa (RT-qPCR por sus siglas en inglés). Sin embargo, muchas economías emergentes han tenido problemas con las demandas actuales de pruebas moleculares debido a limitaciones económicas, técnicas y tecnológicas. Objetivo: Definir un protocolo de diagnóstico potencial para aumentar la capacidad de prueba en las condiciones actuales y posteriores a la pandemia. Métodos: Revisamos la literatura, las patentes y las aplicaciones comerciales, en busca de alternativas. Resultados: Encontramos un buen potencial en muestras de saliva, inactivación viral y extracción rápida de ARN por calentamiento; el uso de una tecnología isotérmica como la amplificación isotérmica mediada por horquillas (LAMP, por sus siglas en inglés) y la visualización del resultado de la prueba a simple vista mediante colorimetría o turbidez en el tubo. Conclusiones: Las muestras de saliva con extracción rápida de ARN por calentamiento y LAMP colorimétrico son opciones prometedoras para países con limitaciones económicas y de infraestructura.

ABSTRACT

Resumen Introducción: La naturaleza tropical está experimentando una amenaza sin precedentes que incluye comunidades de peces costeros que requieren un constante seguimiento de la presencia de especies. El uso simultáneo de varios métodos de monitoreo debería reducir el sesgo causado por la selectividad de cada método. Objetivo: Este estudio uso cuatro diferentes métodos de muestreo a lo largo de dos años para evaluar y comparar los ensamblajes de peces en el Área Marina de Manejo Bahía Santa Elena, Pacífico de Costa Rica. Métodos: Examinamos los cambios en la riqueza y composición de especies entre épocas de afloramiento y no afloramiento entre julio de 2019 y febrero de 2020. Aplicamos censos visuales, cámaras remotas submarinas; líneas de fondo; y pesca deportiva. Resultados: Identificamos 140 especies de peces (54 familias); las cámaras submarinas remotas detectaron el 83 %, seguido por los censos visuales submarinos (65 %), la pesca deportiva (16 %) y las líneas de fondo (14 %). Solo el método de pesca deportiva detectó diferencias en la riqueza y composición de especies entre temporadas. Conclusión: Las cámaras remotas parecen ser el mejor método para el conteo de especies y la pesca deportiva para detectar diferencias estacionales en las costas tropicales similares a la aquí estudiada.


Abstract Introduction: Tropical nature is experiencing an unprecedented threat that includes coastal fish communities that requires a close monitoring of species presence. The simultaneous use of several monitoring methods should reduce the bias caused by the selectivity of each method. Objective: This study used four different sampling methods over two years to assess and compare fish assemblages in the Santa Elena Bay Marine Management Area (AMM-BSE), North Pacific of Costa Rica. Methods: We examined changes in species richness and composition between upwelling and non-upwelling seasons from July 2019 and February 2020. We applied visual censuses, underwater remote cameras; bottom lines; and sport fishing. Results: We identified 140 species of fish (54 families); remote underwater cameras detected 83 %, followed by underwater visual censuses (65 %), sport-fishing (16 %) and bottom lines (14 %). Only the sport-fishing method detected differences in species richness and composition between seasons. Conclusion: Remote cameras appear to be the best method for species counts, and sport-fishing to detect seasonal differences in tropical coasts similar to the one studied here.

ABSTRACT

Abstract Ischemic strokes secondary to occlusion of large vessels have been described in patients with COVID-19. Also, venous thrombosis and pulmonary thromboembolism have been related to the disease. Vascular occlusion may be associated with a prothrombotic state due to COVID-19-related coagulopathy and endotheliopathy. Intracranial hemorrhagic lesions can additionally be seen in these patients. The causative mechanism of hemorrhage could be associated with anticoagulant therapy or factors such as coagulopathy and endotheliopathy. We report on cases of ischemic, thrombotic, and hemorrhagic complications in six patients diagnosed with SARS-CoV-2 infection. Chest computed tomography (CT) showed typical SARS-CoV-2 pneumonia findings in all the cases, which were all confirmed by either serology or reverse transcription polymerase chain reaction (RT-PCR) tests.

ABSTRACT

El adenocarcinoma pancreático ductal (APD) es la cuarta causa de muerte por cáncer y se proyecta que para el 2030 ocupe el segundo lugar. El pronóstico es sombrío, siendo la sobrevida menor a 9% en 5 años. Se consideró durante mucho tiempo a la resección quirúrgica como el único tratamiento curativo, sin embargo, sólo el 15 a 20% de los pacientes pueden ser beneficiados con la misma. La clasificación pre terapéutica más utilizada es la del National Comprehensive Cáncer Network (NCCN), basada en la relación del tumor con estructuras vasculares, clasificándolos en tumores "resecables", de resección límite "Borderlines" y "localmente avanzados". Se presenta el primer caso registrado en Paraguay de APD con infiltración de la Vena Mesentérica Superior (VMS) tratado con duodenopancreatectomía cefálica (DPC) asociada a resección vascular mayor.


Pancreatic ductal adenocarcinoma (PDA) is the fourth leading cause of cancer death and is projected to rank second by 2030. The prognosis is bleak, with survival being less than 9% in 5 years. For a long time, surgical resection was considered the only curative treatment, however, only 15 to 20% of patients can benefit from it. The most widely used pre-therapeutic classification is that of the National Comprehensive Cancer Network (NCCN), based on the relationship of the tumor with vascular structures, classifying them into "resectable", "borderline" and "locally advanced" tumors. We present the first registered case in Paraguay of PDA with infiltration of the Superior Mesenteric Vein (SMV) treated with cephalic duodenopancreatectomy (CPD) associated with major vascular resection.

ABSTRACT

La atresia de coanas se caracteriza por la obliteración de la abertura nasal posterior. Es la anomalía congénita más frecuente de las fosas nasales. Tiene una incidencia de 1 cada 5000 a 7000 neonatos, con predominio en el sexo femenino. Puede presentarse en forma aislada o asociada a otros síndromes como el CHARGE (coloboma [C], malformaciones cardíacas [H], atresia de coanas [A], retraso psicomotor y/o en el crecimiento [R], hipoplasia de genitales [G], malformaciones auriculares y/o sordera [E, por su sigla en inglés]). Las manifestaciones clínicas son la obstrucción nasal, cianosis y dificultad respiratoria desde el nacimiento cuando es bilateral. Las atresias unilaterales se caracterizan por insuficiencia ventilatoria nasal y rinorrea unilateral, y pueden pasar inadvertidas. El diagnóstico se realiza mediante endoscopia y estudios por imágenes. El tratamiento es quirúrgico; existen diferentes técnicas y vías de abordaje. Se presenta el caso de un paciente masculino de 7 años con atresia unilateral de coana derecha con resolución microendoscópica, colocación de tutor externo, con buena resolución.


Choanal atresia is characterized by obliteration of the posterior nasal opening. It is the most common congenital anomaly of the nasal passages. It has an incidence of 1 in 5000 to 7000 newborns; predominantly female. It can occur in isolation or in association with other syndromes such as CHARGE (coloboma [C], cardiac malformations [H], choanal atresia [A], psychomotor and/or growth retardation [R], genital hypoplasia [G], atrial malformations and/or deafness [E]. Clinicallypresents nasal obstruction, cyanosis and respiratory distress from birth when bilateral, unilateral atresias are characterized by nasal ventilatory insufficiency and unilateral rhinorrhea, which may go unnoticed. Diagnosis is made by endoscopy and imaging tests. Treatment is surgical, with different techniques and approaches.A 7-year-old male patient is presented with unilateral atresia of the right choana with microendoscopic resolution, placement of an external tutor, with good resolution.

ABSTRACT

Este trabajo tuvo como objetivo conocer la fiabilidad de la impresora 3D (i3D) aditiva por Matriz de Proceso Digital de Luz (MDLP) Hellbot modelo Apolo®, a través de verificar la congruencia dimensional entre las mallas de modelos impresos (MMi) y su correspondiente archivo digital de origen (MMo), obtenido del software de planificación ortodontica Orchestrate 3D® (O3D). Para determinar su uso en odontología y sus posibilidades clínicas, fue comparada entre cinco i3D de manufactura aditiva, dos DLP, dos por estereolitografía (SLA) y una por Depósito de Material Fundido (FDM). La elección de las cinco i3D se fundamentó en su valor de mercado, intentando abarcar la mayor diversidad argentina disponible. Veinte modelos fueron impresos con cada i3D y escaneados con Escáner Intraoral (IOS) Carestream modelo 3600® (Cs3600). Las 120 MMi fueron importadas dentro del programa de ingeniería inversa Geomagic® Control X® (Cx) para su análisis 3D, consistiendo en la superposición de MMo con cada una de las MMi. Luego, una evaluación cualitativa de la desviación entre la MMi y MMo fue realizada. Un análisis estadístico cuidadoso fue realizado obteniendo como resultado comparaciones en 3d y 2d. Las coincidencias metrológicas en la superposición tridimensional permitieron un análisis exhaustivo y fácilmente reconocible a través de mapas colorimétricos. En el análisis bidimensional se plantearon planos referenciados dentariamente desde la MMo, para hacer coincidir las mediciones desde el mismo punto de partida dentaria. Los resultados fueron satisfactorios y muy alentadores. Las probabilidades de obtener rangos de variabilidad equivalentes a +/- 50µm fueron de un 40,35 % y de +/- 100µm un 71,04 %. Por lo tanto, te- niendo en cuenta las exigencias de congruencia dimensional clínicas de precisión y exactitud a las cuales es sometida nuestra profesión odontológica, se evitan problemas clínicos arrastrados por los errores dimensionales en la manufactura (Cam) (AU)


The objective of this study was to determine the reliability of the Hellbot Apollo® model additive 3D printer (i3D) by Matrix Digital Light Processing (MDLP) by verifying the dimensional congruence between the printed model meshes (MMi) and their corresponding digital source file (MMo), obtained from the Orchestrate 3D® (O3D) orthodontic planning software. A comparison was made between five i3D of additive manufacturing, two DLP, two by stereolithography (SLA), and one by Fused Material Deposition (FDM), to determine its use in dentistry and its clinical possibilities. The choice of the five i3D was based on their market value, trying to cover most of the Argentinean diversity available. Twenty models were printed with each i3D and scanned with Carestream Intraoral Scanner (IOS) model 3600® (Cs3600). The 120 MMi were imported into the reverse engineering program Geomagic® Control X® (Cx) for 3D analysis, consisting of overlaying MMo with each MMi. Then, a qualitative evaluation of the deviation between MMi and MMo. Also, a careful statistical analysis was performed, resulting in 3d and 2d comparisons. Metrological coincidences in three-dimensional overlay allowed a comprehensive and easily recognizable analysis through colorimetric maps. In the two-dimensional analysis, dentally referenced planes were proposed from the MMo, to match the measurements from the same dental starting point. The results were satisfactory and very encouraging. The probabilities of obtaining ranges of variability equivalent to +/- 50µm were 40.35 % and +/- 100µm 71.04 %. Therefore, considering the demands of clinical dimensional congruence, precision, and accuracy to which our dental profession it is subjected, clinical problems caused by dimensional errors in manufacturing (Cam) are avoided (AU)

ABSTRACT

El granuloma piógeno es una lesión benigna, reactiva y multifactorial que resulta de le- siones repetitivas, microtraumatismos e irritación local en piel o mucosas y cambio hormonal. Cuando aparece en la cavidad oral tiene predilección por la encía vestibular, pero es importante que el odontólogo esté consciente y familiarizado con el hecho de que puede estar localizado en otras áreas anatómicas. Clínicamente se presenta como lesión hiperplásica altamente vascularizada, de tamaño generalmente no mayor a 2 cm, pediculada en la base o sésil y de lento crecimiento. Sin mostrar preferencia por edad o sexo, tiende a aparecer principalmente en encías, labios y mucosa oral, siendo muy pocos los casos reportados en el área lingual. Es por ello que, en este artículo, nos referimos a un caso de ubicación inusual, en conjunto con una revisión de la literatura (AU)


Pyogenic granuloma is a benign, reactive, and multifactorial lesion caused by repetitive injuries, microtrauma and local irritation on the skin or mucous membranes, and hormonal change. When it appears in the oral cavity, it has a predilection for the vestibular gingiva, but the dentist must be aware and familiar with the fact that it can be present in other anatomi- cal areas. Clinically, it is presented as a hyperplasic injury highly vascular-related, with a size generally no bigger than 2 cm, pedunculated in base or sessile, and slow in growth. Without showing any preference in age or gender, it tends to appear mainly on the gums, lips, and oral mucosae, with very few, reported cases in the lingual area. Therefore, in this study, we refer to a case of unusual localization with a literature review (AU)

Introduction: 25% of elbow dislocations correspond to complex dislocations, which are defined as those dislocations that are accompanied by bone injuries, being more unstable than pure or simple dislocations. These lesions have set an important therapeutic challenge, since historically poor functional results have been obtained. The objective of this study is to review the literature on the treatment of complex elbow dislocations with posterolateral instability, and to assess the results of the multiple therapeutic options. Materials and Methods: The systematized search was carried out using the Pubmed search engine, obtaining a total of 1450 articles, of which 32 met the established inclusion and exclusion criteria. Results: The studies analyzed were of a low level of evidence, III or IV, corresponding mostly to retrospective case series. The large number of existing therapeutic variants stands out, with different therapeutic protocols, which yield similar functional results. Conclusions: Complex elbow dislocations correspond to complex injuries, capable of causing important functional sequelae in patients. The establishment of therapeutic protocols is key to obtaining better functional results.

ABSTRACT

ABSTRACT BACKGROUND: Clinical assessment of head and neck cancers is highly challenging owing to the complexity of regional anatomy and wide range of lesions. The diagnostic evaluation includes detailed physical examination, biopsy and imaging modalities for disease extent and staging. Appropriate imaging is done to enable determination of precise tumor extent and involvement of lymph nodes, and detection of distant metastases and second primary tumors. OBJECTIVE: To evaluate the initial staging discrepancy between conventional contrasted computed tomography (CT) and 18F-fluorodeoxy-D-glucose positron emission tomography/computed tomography (18F-FDG PET/CT) and its impact on management plans for head and neck malignancies. DESIGN AND SETTING: Prospective cross-sectional study in two tertiary-level hospitals. METHODS: This study included 30 patients with primary head and neck malignant tumors who underwent contrasted computed tomography and whole-body 18F-FDG PET/CT assessments. The staging and treatment plans were compared with the incremental information obtained after 18F-FDG PET/CT. RESULTS: 18F-FDG PET/CT was found to raise the stage in 33.3% of the cases and the treatment intent was altered in 43.3% of them, while there was no management change in the remaining 56.7%. 18F-FDG PET/CT had higher sensitivity (96% versus 89.2%) and accuracy (93% versus 86.7%) than conventional contrast-enhanced computed tomography. CONCLUSION: Our study demonstrated that 18F-FDG PET/CT had higher sensitivity and accuracy for detecting head and neck malignancy, in comparison with conventional contrast-enhanced computed tomography. 18F-FDG PET/CT improved the initial staging and substantially impacted the management strategy for head and neck malignancies.

ABSTRACT

A obesidade é definida pelo excesso de gordura corporal acumulada no tecido adiposo quando o indivíduo atinge valores de IMC igual ou superior a 30 Kg/m2. Constitui um dos principais fatores de risco para várias doenças não transmissíveis (DNTs) como por exemplo, diabetes mellitus tipo 2 (DM2), doenças cardiovasculares, hipertensão arterial, acidente vascular cerebral e até mesmo o câncer. Embora a obesidade esteja diretamente relacionada com o consumo calórico excessivo em relação ao gasto energético diário, sua etiologia pode estar associada aos baixos níveis de atividade física, às alterações neuroendócrinas e aos fatores genéticos. Considerando o componente genético, esta pode ser classificada como sindrômicas e estar associada às alterações cromossômicas estruturais ou numéricas, ou como não sindrômica, quando relacionada, principalmente, com os polimorfismos de nucleotídeos simples (SNPs) em alelos que atuam como herança monogênica, ou ainda com a interação vários genes (poligênica multifatorial). Apesar de existirem muitas etiologias diferentes, normalmente a obesidade é tratada a partir da mesma abordagem, desconsiderando a fisiologia que a desencadeou. Dessa forma, o objetivo do presente trabalho foi abordar a obesidade genética não sindrômica por meio a) da descrição breve de perspectiva histórica sobre seu entendimento; b) da exposição dos principais mecanismos moleculares envolvidos com o controle de peso; c) da compilação dos principais genes e SNPs relacionados; d) da definição dos principais genes; e e) da abordagem das principais perspectivas de intervenção.


Obesity is defined as excess body fat accumulated in the adipose tissue when the individual reaches BMI values equal to or greater than 30 kg/m2. It is one of the main risk factors for several non-communicable diseases (NCDs), such as Type 2 Diabetes mellitus (T2D), cardiovascular diseases, high blood pressure, stroke and even cancer. Although obesity is directly related to excessive calorie intake in relation to daily energy expenditure, its etiology may be associated with low levels of physical activity, neuroendocrine changes, and genetic factors. Considering the genetic component, it can be classified as syndromic and be associated with chromosomal or numerical changes, or as non-syndromic and being related mainly to single nucleotide polymorphisms (SNPs) in alleles that act as monogenic inheritance, or with an interaction of several genes (multifactorial polygenic). Although there are many different etiologies, obesity is usually treated using the same approach, disregarding the physiology that triggered it. Thus, the aim of this study was to address non-syndromic genetic obesity through a) a brief description of a historical perspective on its understanding; b) the exposure of the main molecular mechanisms involved in weight control, c) the compilation of the key genes and related SNPs, d) the definition of the key genes and e) the approach of the main intervention representations.

ABSTRACT

Abstract Background: Right ventricular dysfunction is a major complication in chronic obstructive pulmonary disease (COPD) and, despite its prognostic implications, is rarely considered in routine clinical analysis. Objectives: To compare RV function variables with standard and advanced echocardiographic techniques in patients with stable COPD and controls. Methods: Twenty COPD patients classified as GOLD ≥ II (13 men aged 68.4 ± 8.3 years) and 20 matched controls were compared. Myocardial strain/strain rate indices were obtained by tissue Doppler and two-dimensional speckle tracking echocardiography. Right ventricular ejection fraction was obtained with three-dimensional software. Free wall myocardial thickness (FWMT) and tricuspid annular systolic excursion (TAPSE) were also measured. Numerical variables were compared between groups with Student's t-test or the Mann-Whitney test. Associations between categorical variables were determined with Fisher's exact test. P-values < 0.05 were considered statistically significant. Results: All myocardial deformation indices, particularly global longitudinal strain (-17.2 ± 4.4 vs -21.2: ± 4.4 = 0.001) and 3D right ventricular ejection fraction (40.8 ± 9.3% vs 51.1 ± 6.4% p <0.001) were reduced in COPD patients. These patients presented higher right ventricular FWMT and lower TAPSE values than controls. Conclusion: Myocardial deformation indices, either tissue Doppler or speckle tracking echocardiography and 3D right ventricular ejection fraction, are robust markers of right ventricular dysfunction in patients with stable COPD. Assessing global longitudinal strain by speckle tracking echocardiography is a more practical and reproducible method.

ABSTRACT

Abstract Background: Uncontrolled blood pressure has been associated with poor adherence to drug treatment. Objectives: To assess blood pressure control in hypertensive patients attending primary health centers after implementation of a pharmaceutical follow-up program in a city of the north of Brazil. Methods: Observational, cross sectional, descriptive study with 163 hypertensive patients attending public primary health care centers - one located on the riverside and one in the urban area of the city of Santarem, western Pará, Brazil. Adherence to the anti-hypertensive treatment was assessed using the eight-item Morisky test. Pharmacotherapy follow-up (Dader method) of patients with uncontrolled hypertension and non-adherent to anti-hypertensive treatment was performed. Results of the normality test showed that the data did not follow a normal distribution. Continuous variables were then compared using the Wilcoxon signed-rank test, and categorical variables by the likelihood ratio and the McNemar tests. Statistical significance was set at 5%. Results: Of the total sample, 94.5% were not adherent to anti-hypertensive drug therapy and 77.2% had uncontrolled hypertension. Adherence rate was higher in men than women (p=0.006). Pharmacotherapy follow-up improved blood pressure levels, particularly systolic blood pressure (p<0.001). Conclusion: An individualized pharmacotherapeutic follow-up, considering regional and cultural specificities, can contribute to the treatment of hypertensin in the primary care.
