    La presente investigación consideró como objetivo determinar la relación entre la Planificación Estratégica y la Toma de Decisiones en la Sociedad Nacional de Industrias, 2021; considerando una metodología de enfoque cuantitativo, alcance correlacional, diseño no experimental y corte transversal; considerando una muestra de 105 colaboradores de la organización en cuestión. El instrumento utilizado fue el cuestionario, el cual estuvo conformado por 19 ítems en escala Likert con 5 opciones de respuesta; contando con un Alfa de Cronbach igual a 0.766. La etapa de resultados se realizó considerando el análisis descriptivo, de normalidad e inferencial. En esta última se utilizó la prueba Rho de Spearman para la comprobación de hipótesis, tanto general como específicas; permitiendo así concluir que la planificación estratégica guarda relación con la toma de decisiones en la Sociedad Nacional de Industrias, en un nivel de correlación positivo moderado (Rho igual a 0.670) con un valor de significancia igual a 0.043

    Distinguishing ‘dual’ from ‘duplicated’ right coronary artery: Revisiting the nomenclature

    We report a case of a 53-year-old man with a "short RCA" seen coursing within the proximal part of the right atrioventricular (AV) groove and terminating in the mid-portion of the right AV groove and a "long RCA" seen to have a proximal course outside the right AV groove, over the free wall of the right ventricle, where it gave rise to the right ventricular and acute marginal branches before returning to the right AV groove in its distal course. The discussion highlights the need for revisiting the nomenclature of "dual RCA and drawing a distinction between "dual" and "duplicated" RCA

    PURPOSETo identify the optimum strength of advanced modeled iterative reconstruction (ADMIRE) to achieve the best subjective and objective image quality when combining three-dose reduction strategies, ultra-high-pitch computed tomography coronary angiography (FLASH CTCA; with single-dose ivabradine to lower heart rate), low tube voltage, and ADMIRE.METHODSSixty consecutive patients underwent FLASH CTCA at 100 kVp in this single-center prospective study. Single-dose ivabradine was administered to patients whose heart rate was above 75 bpm. Images were reconstructed using the three highest strengths of ADMIRE (A3, A4, and A5). Objective and subjective image quality (using a Likert scale) were evaluated in the three datasets.RESULTSThe signal strength remained unchanged but mean noise significantly reduced across the increasing strengths of ADMIRE [signal: 513.78 ± 101.7 Hounsfield units (HU) at A3, 515.6 ± 100.5 HU at A4, and 519.7 ± 107.9 HU at A5; noise: 23.4 ± 4.5 HU at A3, 20.2 ± 3.6 HU at A4, and 17.2 ± 3.3 HU at A5]. Signal-to-noise and contrast-to-noise ratios were the highest at A5, and A5 offered significantly higher Likert scores in image noise, vessel sharpness, and overall image quality than A3 or A4. Additionally, A5 did not interfere with image interpretation in any patient.CONCLUSIONUsing all three dose reduction strategies during FLASH CTCA along with single-dose ivabradine administration ensures minimal radiation exposure in daily practice. In this study, A5 datasets had the best overall subjective and objective image quality despite their “plastic appearance”. In the future, enhanced dose reduction can be obtained by further lowering tube voltages

    A Newly Developed Pericardial Tuberculoma During Antituberculous Therapy

    Tuberculosis generally affects the respiratory tract. In developing nations, the pericardium is the most common location of extrapulmonary tuberculosis; however, tuberculous pericarditis rarely appears as a localized mass or tuberculoma. We present here a case of a 62-year-old woman with pericardial tuberculoma. She had a history of effusive tuberculous pericarditis and drainage. Because she had taken regular medication over a period of six months, the pericardial mass with an adjacent lung nodule newly detected on the chest radiogram was initially suspected of being invasive lung cancer. Prior to pathologic confirmation, precise information from imaging tests, including computed tomography, magnetic resonance imaging, and positron emission tomography-computed tomography are helpful when making decisions regarding which methods should be used for surgical approach and treatment. Through imaging, our case showed typical features of pericardial tuberculoma and a favorable clinical course after two months with a change in antituberculous therapy

    Tuberculous dilated cardiomyopathy: an under-recognized entity?

    Get PDF
    BACKGROUND: Tuberculosis (TB) is a common public health problem in many parts of the world. TB is generally believed to spare these four organs-heart, skeletal muscle, thyroid and pancreas. We describe a rare case of myocardial TB diagnosed on a post-mortem cardiac biopsy. CASE PRESENTATION: Patient presented with history suggestive of congestive heart failure. We describe the clinical presentation, investigations and outcome of this case, and review the literature on the involvement of myocardium by TB. CONCLUSION: Involvement of myocardium by TB is rare. However it should be suspected as a cause of congestive heart failure in any patient with features suggestive of TB. Increasing recognition of the entity and the use of endomyocardial biopsy may help us detect more cases of this "curable" form of cardiomyopathy

    Intracardiac left atrial tuberculoma in an eleven-month-old infant: case report

    <p>Abstract</p> <p>Background</p> <p>Cardiac tuberculosis is rare and usually manifests as tuberculous pericarditis. Involvement of other part of the heart is unusual and descriptions in the pediatric literature are confined to few case reports regarding mainly myocardial tuberculosis.</p> <p>Case presentation</p> <p>We describe a case of pulmonary miliary tuberculosis associated with intracardiac left atrial tuberculoma in an immunocompetent eleven-month-old infant successfully treated with surgery and antituberculous therapy.</p> <p>Conclusion</p> <p>Although unusual, involvement of endocardium in disseminated tuberculosis should be kept in mind.</p
