IMAGING DIAGNOSIS-SPONTANEOUS PNEUMOMEDIASTINUM SECONDARY TO PRIMARY PULMONARY PATHOLOGY IN A DALMATIAN DOG.

A 1.5-year-old, 23 kg intact male Dalmatian dog was evaluated for acute respiratory insufficiency without a previous history of trauma or toxic exposition. Imaging revealed pneumomediastinum, pneumothorax, diffuse unstructured interstitial pulmonary pattern, pulmonary interstitial emphysema, and pneumoretroperitoneum. Histopathological evaluation of the lungs revealed perivascular and peribronchial emphysema, mild lymphocytic interstitial pneumonia with atypical proliferation of type II pneumocytes in bronchioles and alveoli. A lung disease resembling fibrosing interstitial pneumonia in man and cats has been previously reported in Dalmatians and should be included as a differential diagnosis for Dalmatians with this combination of clinical and imaging characteristics.

Reverse Sneezing in Dogs: Observational Study in 30 Cases.

Reverse sneezing (RS) is a frequent reason for veterinary consultation, but there is scarce clinical information. The aim of this study was to describe clinical characteristics in a cohort of 30 dogs with RS. Signalment, clinical features, results of diagnostic tests, final diagnosis, and evolution were retrospectively evaluated. Sex and neuter status were equally distributed into diagnosis categories. A significantly higher representation of toys (<5 kg, 50%) and small-sized dogs (5−15 kg, 27%), in comparison to medium (15−30 kg, 17%) and large-sized dogs (>30 kg, 7%), was found. RS was the main owner concern in many of the cases (67%). Many cases presented chronic RS (60%, > 3 months), with more than one episode a week (60%). Most cases had an additional clinical respiratory sign (63%) and an unremarkable physical examination (63%). Inflammatory airway disorders were present in 57% of the cases, followed by anatomical−functional disorders (27%), and nasal/nasopharyngeal foreign bodies (10%). Two dogs (7%) remained as open diagnoses. Episodes of RS were persistent despite the treatment in 61% of the dogs with follow-up. Although some dogs manifest infrequent episodes of RS, being otherwise normal, RS should be considered a marker of potential irritation of the nasopharyngeal mucosa and should always be sufficiently investigated.

Clinical and Electrocardiographic Findings for Predicting the Severity of Pulmonary Valve Stenosis in Dogs.

Pulmonary valve stenosis (PS) in dogs is usually suspected due to the presence of a heart murmur and clinical signs. Echocardiography is needed to confirm the diagnosis and define the severity of PS. This retrospective study evaluated the utility of clinical and electrocardiographic (ECG) findings in the prediction of PS severity. Data regarding heart murmur and ECG analysis were gathered. Ninety-seven dogs with PS were included. A murmur grade ≥IV/VI was predictive of severe PS (area under curve (AUC) = 0.71; sensitivity (Se) = 95%; specificity (Sp) = 33%; p = 0.003). In lead II, P wave amplitude >0.35 mV (AUC = 0.67; Se = 31%; Sp = 100%; p = 0.038), Q wave < 0.15 mV (AUC = 0.70; Se = 70%; Sp = 59%; p = 0.0015), R wave < 0.87 mV (AUC = 0.66; Se = 67%; Sp = 69%; p = 0.006), and S wave > 0.37 mV (AUC = 0.80; Se = 72%; Sp = 85%; p < 0.0001) were predictive of severe PS. The extent of right deviation of the mean electrical axis of the QRS complex was correlated with the pulmonary pressure gradient (r = 0.648; p < 0.0001). In conclusion, a systolic murmur with intensity ≥IV/VI, a P wave amplitude >0.35 mV, low amplitude of Q and R waves, deep S waves in lead II, and right axis deviation of the QRS complex in a young dog are predictive of severe PS.

Left ventricular inflow tract obstruction secondary to a myxoma in a dog.

This is the first description of a left ventricular inflow tract obstruction secondary to a myxoma in a dog. A 4 yr old, male fox terrier presented with a 1 mo history of cough and exercise intolerance. Expiratory dyspnea, pulmonary crackles, irregular cardiac rhythm, and a grade 4/6 pansystolic cardiac murmur over the left cardiac apex were the most important features on physical examination. The electrocardiogram revealed atrial fibrillation. Thoracic radiographs showed left-sided cardiac enlargement and mild pulmonary edema, especially in the hilar area. Two-dimensional transthoracic echocardiography showed severe left atrial dilation and a homogenous, echodense mass involving both leaflets of the mitral valve and the posteromedial papillary muscle, inducing mitral stenosis. Spectral Doppler echocardiography was consistent with severe left ventricular inflow tract obstruction secondary to a mass. Therapy for congestive heart failure was prescribed. Follow-up examinations of the dog 1 mo, 2 mo, and 6 mo after diagnosis showed an improvement in clinical signs, but similar echocardiographic features. Eleven months after diagnosis, the dog was euthanized at the owner's request because of recurrent congestive heart failure. The postmortem examination showed the cardiac tumor was consistent with a myxoma.

Thoracic omentalization for long-term management of neoplastic pleural effusion in a cat.

CASE DESCRIPTION: An 11-year-old neutered female domestic longhair cat was evaluated because of a 1-week history of progressive dyspnea, signs of depression, and loss of appetite. A histiocytic sarcoma had been excised from the mammary gland 6 weeks earlier. CLINICAL FINDINGS: Physical examination findings were consistent with pleural effusion, and thoracic and abdominal radiography and ultrasonography revealed pleural effusion, a thoracic mass involving the aorta and pulmonary artery, and a caudal abdominal mass that most likely represented enlarged iliac lymph nodes. Cytologic examination of the pleural fluid and fine-needle aspirates from the iliac and right popliteal lymph nodes revealed abundant cells with neoplastic characteristics of indeterminate origin. The clinical diagnosis was generalized malignant neoplasia. TREATMENT AND OUTCOME: Pleural drainage was necessary every 5 to 6 days. Exploratory thoracotomy and biopsy of the mass were recommended for better characterization of the thoracic disease. Simultaneously, palliative treatment by advancement of the omentum into the thorax was performed. A final diagnosis of disseminated histiocytic sarcoma was made, and treatment with doxorubicin was begun after surgery. During the 13 months after surgery, the cat was free from signs of respiratory tract disease and had normal activity levels with good exercise tolerance. Fifteen months after surgery, the cat's clinical condition worsened and the cat died. CLINICAL RELEVANCE: Findings suggested that thoracic omentalization may be considered for palliative treatment of cats with refractory neoplastic pleural effusion when frequent thoracocentesis is necessary and other treatments are not suitable.

Resting Energy Expenditure, comparison of predictive formulas with bioimpedance: Peruvian population / Gasto Energético en Reposo, comparación de fórmulas predictivas con la bioimpedancia: población peruana

Introduction: In areas with limited access to healthcare systems, Resting Energy Expenditure (REE) estimation is performed using predictive equations to calculate an individual's caloric requirement. One problem is that these equations were validated in populations with different characteristics from those in Latin America, such as race, height, or body mass, leading to potential errors in the prediction of this parameter. Objective: To determine the REE using predictive formulas compared with bioimpedance in Peruvians. Materials and methods: A comparative analytical cross-sectional study with secondary database analysis of the CRONICAS cohort. Results: we worked with a total of 666 subjects. The Mjeor equation was the one with the highest rating of 0.95, a lower mean absolute percentage error (MAPE) of 4.69%, and equivalence was found with the REE values. In the multiple regression, it was observed that the Mjeor equation was the one that least overestimated the REE, increasing 0.77 Kcal/day (95% CI: 0.769-0.814; p<0.001) for each point that increased the REE determined by bioimpedance. The strength of association between Mjeor and bioimpedance was 0.9037. Furthermore, in the regression of the data (weight, height, age) in the Mjeor equation it was observed that the coefficients obtained were the same as those used in the original equation. Conclusions: The Mjeor equation seems to be the most adequate to estimate the REE in the Peruvian population. Future prospective studies should confirm the usefulness of this formula with potential utility in primary health care(AU)

Introducción: En zonas con acceso limitado a sistemas de salud, la estimación del Gasto Energético en Reposo (GER) se realiza utilizando ecuaciones predictivas para calcular el requerimiento calórico de un individuo. Uno de los problemas es que estas ecuaciones fueron validadas en poblaciones con características diferentes a las latinoamericanas, como raza, talla o masa corporal, lo que conlleva a potenciales errores en la predicción de este parámetro. Objetivo: Determinar el GER mediante fórmulas predictivas comparadas con la bioimpedancia en peruanos. Materiales y métodos: Estudio transversal analítico comparativo con análisis secundario de base de datos de la cohorte CRONICAS. Resultados: Se trabajó con un total de 666 sujetos. La ecuación de Mjeor fue la que obtuvo la puntuación más alta de 0,95, un error medio porcentual absoluto (MAPE) inferior de 4,69%, y se encontró equivalencia con los valores del GER. En la regresión múltiple, se observó que la ecuación de Mjeor fue la que menos sobreestimó el GER, aumentando 0,77 Kcal/día (IC 95%: 0,769-0,814; p<0,001) por cada punto que aumentaba el GER determinado por bioimpedancia. La fuerza de asociación entre Mjeor y bioimpedancia fue de 0,9037. Además, en la regresión de los datos (peso, talla, edad) de la ecuación de Mjeor se observó que los coeficientes obtenidos eran los mismos que los utilizados en la ecuación original. Conclusiones: La ecuación de Mjeor parece ser la más adecuada para estimar el GER en la población peruana. Futuros estudios prospectivos deberán confirmar la utilidad de esta fórmula para su potencial utilidad en la atención primaria de salud(AU)

Actitudes, uso, barreras y conocimientos sobre la medicina basada en la evidencia según el nivel de atención

Introducción: A pesar de la importancia de la medicina basada en la evidencia, es necesario una mejor comprensión de la situación para el desarrollo de esfuerzos educativos y prácticos en función de implementar la medicina basada en la evidencia en el sistema de salud. Objetivo: Determinar la actitud, el uso, las barreras y los conocimientos de la medicina basada en la evidencia en los médicos peruanos según el nivel de atención. Métodos: Se realizó un estudio analítico transversal a través de una encuesta que se aplicó a los médicos peruanos que trabajan en diferentes niveles de atención en salud. Resultados: Se encuestó un total de 1396 médicos. El 64,35 % señaló una actitud positiva hacia la aplicación de la medicina basada en la evidencia. En el caso de las barreras, el 51,01 % no tenía suficiente evidencia relevante; el 49,35 % no contaba con tiempo; el 47,20 % no poseía suficientes habilidades para encontrarla; mientras que el 44,40 % no podía hacer lectura crítica de estas. En cuanto a los accesos de información, casi el 80 % de los participantes reportó que no tiene acceso a ninguna base de datos de las mencionadas. Teniendo en cuenta la comprensión de los términos estadísticos, más de dos tercios de los participantes tenían un alto nivel de comprensión. Conclusiones: Aunque la mayoría de los médicos encuestados tienen un buen conocimiento y una actitud positiva hacia la medicina basada en la evidencia, aún existen barreras y uso de la información que se deben mejorar.

Introduction: Despite the importance of evidence-based medicine, a better understanding of the situation is necessary for developing educational and practical efforts to implement evidence-based medicine in the health system. Objective: To determine the attitude, use, barriers and knowledge of evidence-based medicine in Peruvian doctors according to the level of care. Methods: A cross-sectional analytical study was carried out through a survey that was applied to Peruvian doctors who work at different levels of health care. Results: A total of 1396 physicians were surveyed. 64.35% indicated positive attitude towards the application of evidence-based medicine. In the case of barriers, 51.01% did not have enough relevant evidence; 49.35% did not have time; 47.20% did not have sufficient skills to find it; while 44.40% could not critically read them. Regarding information access, almost 80% of the participants reported that they do not have access to any of the aforementioned databases. Taking into account the understanding of statistical terms, more than two-thirds of the participants had high level of understanding. Conclusions: Although the majority of physicians surveyed have good knowledge and positive attitude towards evidence-based medicine, there are still barriers and use of information that need to be improved.

Broncholithiasis in a cat: clinical findings, long-term evolution and histopathological features.

A 14-year-old neutered male Persian cat was evaluated because of an acute exacerbation of a chronic cough of 2-3 years of duration. Physical examination was normal except for the auscultation of accentuated breath sounds and wheezes cranially on both sides of the chest. Complete blood count, biochemical parameters and urinalysis were normal. Thoracic radiographs showed a generalised nodular pattern with multiple mineral opacities. Oral prednisone and doxycycline were prescribed. Two weeks later, the frequency of the cough was significantly reduced. Terbutaline was recommended for relief of acute exacerbations. Three years later the cat was evaluated again due to a non-related disease that led to the euthanasia of the cat. Concerning its respiratory disease, the cat had experienced nearly asymptomatic periods of 3-6 weeks of duration punctuated by acute exacerbation periods of 7-10 days, during which terbutaline was useful to relieve the cough. Thoracic radiographs showed a mild increase in the size and extent of the pulmonary mineralisation. Histopathologically, mild bronchitis and bronchiectasis were evident, accompanied by calcified bronchial plugs and marked hyperplasia and hypertrophy of the seromucinous glands. Based on clinical and pathoanatomical findings, a final diagnosis of miliary broncholithiasis and bronchiectasis was made. Broncholithiasis should be considered in differential diagnosis of pulmonary mineralisation in cats. When no concomitant diseases are present, this rare disease appears to have a slowly progressive evolution that does not appear to carry a bad prognosis and may be satisfactorily managed with combinations of bronchodilators and corticosteroids.

Factores socioculturales que influyen en las usuarias de 50 años para la toma de Papanicolaou de un Hospital Nasca

Objetivo: El objetivo del presente estudio fue determinar los factores socioculturales en usuarias de 50 años para la toma de Papanicolaou en el hospital Ricardo Cruzado Rivarola de Nasca durante el periodo Diciembre 2021 - Febrero 2022. Materiales y métodos : Realizamos un estudio observacional, analítica, y prospectivo. La población de estudio está constituida por 80 usuarias de 50 años que acuden al hospital Ricardo Cruzado Rivarola para controles de Papanicolaou al consultorio de Ginecología-Obstetricia. La muestra estuvo conformada por 67 usuarias, seleccionadas por muestreo no probabilístico por conveniencia. Resultados: Para el primer análisis, en la regresión simple, se encontró que las mujeres con nivel de conocimientos altos tenían 153% mayor frecuencia de haberse realizado alguna vez un pap y las mujeres con nivel de conocimientos altos tenían 384% mayor frecuencia de haberse realizado alguna vez un PAP, en comparación a quienes tenían un nivel de conocimientos bajo. Luego, en la regresión múltiple se observó que las mujeres con nivel de conocimientos altos tenían 382% mayor frecuencia de haberse realizado alguna vez un PAP, en comparación a quienes tenían un nivel de conocimientos bajo. Conclusiones: El nivel de conocimiento sobre el PAP influye de una manera relevante al haberse realizado un PAP; pero además las mujeres que tuvieron mayor educación fueron las que tuvieron mayor frecuencia de haberlo realizado. Esto sumado a la cantidad de hijos; posiblemente porque en los círculos de mujeres con hijos uno de los temas a tratar es sobre la salud materna y dentro ellos el PAP.

Objective: The objective of this study was to determine the sociocultural factors in 50-year-old users for pap smears at the Ricardo Cruzado Rivarola de Nasca Hospital during the period December 2021 - February 2022. Material and methods: Observational, analytical, and prospective study. The study population is made up of 80 50-year-old users who attend the Ricardo Cruzado Rivarola Hospital for PAP tests at the gynecology-obstetrics office and the sample is 67 users, selected by non-probabilistic sampling for convenience. Results: For the first analysis, in simple and multiple regression, it was found that women with high levels of knowledge had a 384% and 382% higher frequency of having ever undergone a PAP test compared to those with low levels of knowledge. Conclusions: The level of knowledge about the PAP has a relevant influence on having carried out a PAP; but also the women who had a high level were the ones who had the highest frequency of having done it. This added to the number of children; possibly because in the circles of women with children one of the topics to be discussed is about maternal health and within them the PAP.

Inteligencia emocional y estrategias de afrontamiento al estrés en personal de salud

Objetivo: Determinar la relación entre inteligencia emocional y las estrategias de afrontamiento al estrés en trabajadores asistenciales de un Hospital de Tercer Nivel de Atención durante el 2021. Material y método: Se realizó un estudio transversal analítico. Se utilizó dos encuestas: El test de COPE, el cual mide cómo afrontar el estrés y el Inventario de Coeficiente emocional de Bar-On, que mide el nivel de inteligencia emocional. La variable principal fue el afrontamiento al estrés; la independiente, la inteligencia emocional. Resultados: Se trabajó un total de 290 trabajadores asistenciales. La inteligencia emocional se correlacionó significativamente de manera positiva (Pearson = 0.6003) con el afrontamiento al estrés. Las estrategias de afrontamiento al estrés con mayor media fueron planificación, reinterpretación positiva y crecimiento, afrontamiento religioso. Estas estrategias tuvieron una correlación positiva con la inteligencia emocional, estas correlaciones fueron 0.5271, 0.5200 y 0.2051, respectivamente. Para el análisis de regresión múltiple, se observó que el promedio de puntos del Test de BarOn aumentó en 0.261 puntos por cada punto que incrementa el TEST de COPE (coef. = 0,261; IC95%: 0.215 - 0.307); ello ajustado por todas las covariables de interés. Conclusión: Existe una relación entre la inteligencia emocional y el afrontamiento al estrés; también, se encontró relación con las estrategias de afrontamiento al estrés.

Objective: To determine the relationship between emotional intelligence and stress coping strategies in health care workers of a Third Level of Care Hospital during 2021. Methods: An analytical cross-sectional study was carried out. Two surveys were used: the COPE test which measures how to cope with stress and the Bar-On Emotional Coefficient Inventory which measures the level of emotional intelligence. The main variable was coping with stress. The independent variable was emotional intelligence. Results: A total of 290 health care workers were worked. Emotional intelligence was significantly positively correlated (Pearson = 0.6003) with stress coping. The stress coping strategies with the highest mean were planning, positive reinterpretation and growth, and religious coping. These strategies had a positive correlation with emotional intelligence, these correlations were 0.5271, 0.5200 and 0.2051 respectively. For the multiple regression analysis, it was observed that the average BARON test score increased by 0.261 points for each point increase in the COPE TEST (coefficient = 0.261; 95%CI: 0.215 - 0.307); adjusted for all covariates of interest. Conclusion: There is a relationship between emotional intelligence and stress coping. A relationship was also found with stress coping strategies.

Combinaciones de síndrome metabólico y riesgo de diabetes mellitus

RESUMEN Introducción: El síndrome metabólico se asocia con un mayor riesgo de padecer diabetes, por lo que su identificación clínica ayuda a identificar a estos pacientes con alto riesgo. Objetivo: Determinar las combinaciones de síndrome metabólico para el riesgo de diabetes mellitus tipo 2 en una muestra de pobladores peruanos. Métodos: Análisis secundario de un estudio de cohorte de 5 años, de la base de datos del estudio PERU MIGRANT. Los componentes alterados del síndrome metabólico fueron lipoproteínas de alta densidad bajo, hipertrigliceridemia; glucosa, presión arterial y cintura abdominal elevadas. En total 35 subgrupos de componentes: 5 grupos para cada uno de los 5 componentes, 10 grupos de combinaciones de 2 componentes y 3 componentes, 5 grupos para la combinación de 4 componentes. Resultados: En el análisis de regresión múltiple, la glucosa como factor independiente presentó un RR estadísticamente significativo (RR= 9,02; IC: 95 % 2,45 - 33,24; p= 0,001). La combinación de 2 factores, presentaron un RR estadísticamente significativo, la glucosa - cintura abdominal (RR= 7,28; IC: 95 % 1,21 - 43,64; p= 0,030) y glucosa - alta densidad bajo (RR= 10,94; IC: 95 % 2,71 - 44,23; p= 0,001). Finalmente, la combinación de glucosa - lipoproteínas de alta densidad - cintura abdominal tenían 7,80 veces el riesgo de presentar diabetes mellitus tipo 2 versus quienes no lo presentaban (RP= 7,80; IC: 95 % 1,39 - 43,77; p= 0,020). Conclusión: Las combinaciones que incluyen al mismo tiempo glucosa - lipoproteínas de alta densidad - cintura abdominal, fueron las combinaciones que más asociaron.

ABSTRACT Introduction: Metabolic syndrome is associated with an increased risk of diabetes, so its clinical identification helps to identify these patients at high risk. Objective: To determine the combinations of metabolic syndrome for the risk of type 2 diabetes mellitus in a sample of Peruvian population. Methods: 5-year cohort study of secondary analysis of the PERU MIGRANT study database. The altered components of the metabolic syndrome were low high-density lipoprotein, hypertriglyceridemia; and elevated glucose, blood pressure and waist circumference. In total 35 subgroups of metabolic syndrome components: 5 groups for each of the 5 components, 10 groups for combinations of 2 components and 3 components, 5 groups for the combination of 4 components. Results: In the multiple regression analysis, only G as an independent factor presented a statistically significant relative risk (RR= 9.02; 95 % CI 2.45 - 33.24; p= 0.001). In relation to the combination of 2 factors, only the combination of glucose-elevated abdominal waist (RR= 7.28; 95 % CI 1.21 - 43.64; p= 0.030) and glucose-high-density lipoprotein (RR= 10.94; 95 % CI 2.71 - 44.23; p= 0.001) presented a statistically significant relative risk. Finally, patients with the glucose-high-density lipoprotein-abdominal waist combination had 7.80 times the risk of presenting type 2 diabetes mellitus versus those who did not (PR= 7.80; CI: 95 % 1.39 - 43.77; p= 0.020). Conclusion: The combinations that include at the same time glucose - high density lipoproteins - abdominal waist, were the most associated combinations.

Medical treatment in pregnant women with subclinical hypothyroidism: systematic review and meta-analysis / Tratamiento médico en gestantes con hipotiroidismo subclínico: revisión sistemática y meta-análisis

Abstract Objectives: to determine the effectiveness of medical therapy in reducing complications associated with subclinical hypothyroidism during pregnancy. Methods: in 2021, a systematic review of available cohort studies was carried out in three databases, with no publication date limit. Study selection and data extraction were performed in duplicate. Random-effects meta-analysis was performed, and odds ratios were calculated, with the corresponding 95% confidence intervals. Cohort risk of bias was assessed using the Newcastle-Ottawa Scale (NOS). The certainty of the evidence was assessed using the GRADE methodology. Results: five studies were included for qualitative and quantitative synthesis. A statistically significant relationship was found between medical treatment in pregnant women with subclinical hypothyroidism with respect to spontaneous abortion (p=0.03; OR=0.77; CI95%=0.61-0.97), and no statistically significant relationship was found for delivery preterm (p=0.46; OR=1.11; CI95%=0.85-1.44), nor for abrupt placentae (p=0.56; OR=1.60; CI95%=0.33-7.66). Three studies were at moderate risk of bias, and two were at low risk of bias. In all the results the certainty was very low. Conclusions: medical treatment of subclinical hypothyroidism during pregnancy can have a beneficial effect in reducing cases of spontaneous abortion.

Resumo Objetivos: determinar la efectividad de la terapia médica para disminuir las complicaciones asociadas al hipotiroidismo subclínico durante la gestación. Métodos: en el 2021 se realizó una revisión sistemática de estudios de cohortes disponibles en tres bases de datos, sin límite de fecha de publicación. La selección de estudios y extracción de datos se realizaron por duplicado. Se realizó metaanálisis de efectos aleatorios y se calcularon los Odds ratio, con los correspondientes intervalos de confanza al 95%. El riesgo de sesgo de las cohortes se evaluó mediante la escala de Newcastle-Ottawa (NOS). La certeza de la evidencia se evaluó con la metodología GRADE. Resultados: cinco estudios fueron incluidos para síntesis cualitativa y cuantitativa. Se encontró una relación estadísticamente significativa del tratamiento médico en gestantes con hipotiroidismo subclínico con respecto al aborto espontáneo (p=0,03; OR=0,77; IC95%=0,61-0.97), no se encontró relación estadísticamente significativa para parto pre término (p=0.46; OR=1,11; IC95%=0.85-1.44), ni para abrupto placentae (p=0.56; OR=1,60; IC95%=0.33-7.66). Tres estudios tenían riesgo moderado de sesgo, y dos tenían riesgo de sesgo bajo. En todos los resultados la certeza fue muy baja. Conclusiones: el tratamiento médico del hipotiroidismo subclínico durante la gestación puede tener un efecto beneficioso para reducir los casos de aborto espontaneo.

Asociación entre el síndrome metabólico y los niveles de transaminasas / Association between metabolic syndrome and transaminase levels

RESUMEN Introducción: En la patología del síndrome metabólico, de acuerdo con distintas investigaciones y la práctica clínica se han visto manifestaciones de daño hepático. Objetivo: Estimar la prevalencia de transaminasas elevadas (alanina aminotransaminasa y aspartato aminotransaminasa) y determinar su asociación con síndrome metabólico. Métodos: Estudio transversal con procedimientos analíticos. Análisis secundario de los datos generados por el registro electrónico en salud de un policlínico ocupacional. La variable principal fue el diagnóstico del síndrome metabólico. Para definir aspartato aminotransaminasa elevada se consideraron valores > 30 U/L en mujeres y valores > 36 U/L en hombres. Para alanina aminotransaminasa, se consideraron valores > 30 U/L en mujeres y valores > 40 U/L en hombres. Resultados: La prevalencia de síndrome metabólico fue de 21,82 %, de aspartato aminotransaminasa elevada fue del 10,30 % y alanina aminotransaminasa elevada del 16,67 %. En la regresión múltiple, se ajustó por las covariables confusoras sexo, edad, ocupación, índice de masa corporal, fumar, alcohol y actividad física. Se observó que los pacientes con aspartato aminotransaminasa elevada tenían 128 % mayor frecuencia de síndrome metabólico, respecto a quienes no presentaban valores elevados (razón prevalencia= 2,28; IC95 %: 1,64 - 3,17; p< 0,001). Se encontró que los pacientes con alanina aminotransaminasa elevada tenían 148 % mayor frecuencia de presentar síndrome metabólico respecto a quienes no presentaban valores elevados (razón prevalencia= 2,48; IC95 %: 1,77 - 3,47; p< 0,001). Conclusiones: Existe asociación entre las transaminasas hepáticas elevadas y la presencia de síndrome metabólico.

ABSTRACT Introduction: In the pathology of metabolic syndrome, manifestations of liver damage have been seen in different investigations and in clinical practice. Objective: To estimate the prevalence of elevated transaminases (alanine aminotransaminase and aspartate aminotransaminase), and to determine their association with metabolic syndrome. Methods: Cross-sectional with analytical procedure study. Secondary analysis of data generated by the electronic health record of an occupational polyclinic. The main variable was the diagnosis of metabolic syndrome. To define elevated aspartate aminotransaminase, values > 30 U/L in women and values > 36 U/L in men were considered. For alanine aminotransaminase, values > 30 U/L in women and values > 40 U/L in men were considered. Results: The prevalence of metabolic syndrome was 21.82%, elevated aspartate aminotransaminase was 10.30% and elevated alanine aminotransaminase was 16.67%. In multiple regression, we adjusted for the confounding covariates of sex, age, occupation, body mass index, smoking, alcohol and physical activity. It was observed that patients with elevated aspartate aminotransaminase had a 128% higher frequency of presenting metabolic syndrome, compared to those without elevated values (reason prevalence= 2.28; 95% CI: 1.64-3.17; p< 0.001). On the other hand, it was found that patients with elevated alanine aminotransaminase had a 148% higher frequency of presenting metabolic syndrome compared to those without elevated values (reason prevalence= 2.48; 95% CI: 1.77 - 3.47; p< 0.001). Conclusions: There is an association between elevated hepatic transaminases and the presence of metabolic syndrome.

Riesgo de preeclampsia y suplementación de vitamina C y E: revisión sistemática y metanálisis / Risk of preeclampsia and Vitamin C and E supplementation: a systematic review and meta-analysis

RESUMEN Introducción: Se ha sugerido que la preeclampsia puede ser prevenida por la ingesta de vitamina E y C, dado el mecanismo fisiopatológico de esta enfermedad.

El riesgo de sesgo de los ensayos clínicos aleatorios se evaluó mediante la herramienta Cochrane versión 2. Se realizó un metanálisis de efectos aleatorios y se calcularon los riesgos relativos, con los correspondientes intervalos de confianza al 95 %. Resultados: Se incluyeron 7 estudios (n= 1 475). No se encontró asociación estadísticamente significativa del tratamiento con suplementación de vitamina C y E con respecto a la preeclampsia (riesgo relativo: 1,03; IC95 %: 0,78-1,26). Conclusiones: La suplementación dual de vitamina C y E no previene la preeclamsia en gestantes con riesgo de padecer la enfermedad.

ABSTRACT Introduction: It has been suggested that preeclampsia can be prevented by vitamin E and C intake, given the pathophysiological mechanism of this disease. Objective: To determine the joint efficacy of vitamin C and E in the prevention of preeclampsia. Methods: Systematic review of randomized clinical trials. A search of pubmed/medline, SCOPUS, Web of Science, Cochrane Library, EMBASE, and Clinical Trials databases was performed. The risk of bias of the randomized clinical trials was assessed using the Cochrane tool version 2. A random-effects meta-analysis was performed and relative risks were calculated, with corresponding 95 % confidence intervals. Results: Seven studies were included (n= 1 475). No statistically significant association of treatment with vitamin C and E supplementation was found with respect to preeclampsia (relative risks: 1.03; 95 % CI 0.78-1.26). Conclusions: Dual vitamin C and E supplementation does not prevent preeclampsia in pregnant women at risk for the disease.

Factors Associated with Chronic Child Malnutrition in Peru / Factores asociados a la desnutrición crónica infantil en Perú

Abstract: Objective: To investigate factors associated with chronic malnutrition among children aged five and under in Peru. Materials and Methods: Secondary data analysis based on the Peruvian 2018 Demographic and Family Health Survey. Results: Child's age (PR = 1.01; 95% CI: 1.009 to 1.015) and living in a rural area (PR = 1.36; 95% CI: 1.21 to 1.54) were associated with a higher risk of chronic malnutrition in the sample. Educational level, wealth index, and not belonging to the publicly funded Comedor Popular nutrition program, were identified as protective factors to chronic malnutrition. Conclusion: Being under five and living in a rural area was associated with an increased risk of chronic malnutrition in children residing in Peru. A higher wealth index and mother's level of education decrease the chances of chronic malnutrition in children under five years of age.

Resumen: Objetivo: Determinar factores asociados a la desnutrición crónica infantil en niños peruanos menores de cinco años. Materiales y Métodos: Estudio de tipo retrospectivo, basado en un análisis de la base de los datos de la Encuesta Demográfica y de Salud Familiar (ENDES) 2018. Resultados: Se encontró una prevalencia nacional de desnutrición crónica del 9,7% (n=2097) con diferencias según región geográfica de residencia. Se evidenció en el modelo ajustado que la edad del niño mayor de 25 meses (PRa=1,25; IC95%: 1,13 a 1,38, p<0,001) y vivir en zona rural (PR=1,36; IC95%: 1,21 a 1,54) con desnutrición crónica. El tener un mayor nivel de instrucción, un mayor índice de riqueza y no pertenecer al programa comedor popular estuvieron asociados como factores protectores para presentar desnutrición crónica. Conclusiones: La edad de los niños y residir en una zona rural se asocia a mayor riesgo de presentar desnutrición crónica en los niños menores de cinco años.

Asociación entre enfermedad por reflujo gastroesofágico e intensidad de la actividad física en una muestra de pobladores peruanos

Introducción: la nutrición adecuada, dejar de fumar y de beber alcohol son medidas preventivas y de tratamiento, ayudan a prevenir complicaciones de la enfermedad por reflujo gastroesofágico. Sin embargo, aún existen dudas sobre la intensidad de la actividad física y sus beneficios en el desarrollo de esta enfermedad. Objetivo: determinar la asociación entre la actividad física y la enfermedad por reflujo gastroesofágico en una muestra de peruanos. Metodología: estudio transversal analítico que utilizo una base de datos secundarias del estudio COHORT CRONICAS. La variable principal fue la presencia o no de enfermedad por reflujo gastroesofágico, lo cual se determinó a través de un autoinforme por diagnóstico médico. La variable independiente fue la actividad física, cuyos niveles fueron definidos de acuerdo con el protocolo del cuestionario internacional de actividad física, la que se dicotomizó en "bajo" y "medio/alto". Resultados: se trabajó con un total de 3211 sujetos. La prevalencia de reflujo gastroesofágico fue 4,48% y el 5,36% practicaba actividad física moderada/alta. En la regresión múltiple, se observó que los pacientes con actividad física baja tenían 391% mayor frecuencia de presentar reflujo gastroesofágico, respecto a quienes realizaban actividad física moderado/alta. Luego del ajuste de las covariables: sexo, edad, estatus socioeconómico, estado de fumador, bebedor de alcohol, actividad física e índice de masa corporal; se obtuvo un RP=4,91; IC95%: 1,19 - 20,23. Conclusiones: el estudio mostró que la actividad física de intensidad moderada/alta se asocia con una menor prevalencia de enfermedad por reflujo gastroesofágico. Si los resultados actuales se confirman en investigaciones futuras, los hallazgos de este estudio podrían ser importantes para la prevención y el tratamiento del reflujo gastroesofágico, a través de la intensidad de la actividad física.

Introduction: Adequate nutrition, smoking cessation and alcohol cessation are preventive and treatment measures, help prevent complications of gastroesophageal reflux disease. However, there are still doubts about the intensity of physical activity and its benefits in the development of the disease. Objective: To determine the association between physical activity and gastroesophageal reflux disease in a sample of Peruvian population. Methods: Analytical cross-sectional study with the use of secondary databases from the COHORT CRÓNICAS study. The main variable was the presence or absence of gastroesophageal reflux disease, which was determined through a self-report by medical diagnosis. The independent variable was physical activity, whose levels were defined according to the protocol of the international physical activity questionnaire. This variable was dichotomized into "low" and "medium / high". Results: A total of 3211 subjects were worked on. The prevalence of gastroesophageal reflux was 4.48% and 5.36% practiced moderate / severe physical activity. In the multiple regression, it was observed that patients with low physical activity had 391% greater frequency of presenting gastroesophageal reflux, compared to those who carried out moderate / high physical activity; After adjustment for the covariates: sex, age, socioeconomic status, smoking status, alcohol drinker, physical activity and body mass index; a PR=4.91; 95%CI: 1.19 - 20.23 was obtained. Conclusions: The study showed that moderate / high intensity physical activity is associated with a lower prevalence of gastroesophageal reflux disease. If the current results are confirmed in future research, the findings of this study could be important for the prevention and treatment of gastroesophageal reflux disease, through the intensity of physical activity.

Factores asociados al fenotipo delgado metabólicamente obeso en pobladores peruanos

Introducción: Los pacientes con el fenotipo delgado metabólicamente obeso (DMO) pueden presentar el mismo riesgo que los obesos clásicos para desarrollar enfermedades crónicas a largo plazo. No obstante, la prevalencia y los factores que se encuentran asociados este varía de acuerdo con la población estudiada. Objetivo: determinar la prevalencia y los factores se encuentran asociados al fenotipo DMO en el Perú. Métodos: Estudio analítico de corte transversal. Análisis secundario de la base de datos del estudio PERU MIGRANT. Los factores asociados que se consideraron fueron: edad (30-44 años, de 45-59 años, y 60 a más años), sexo, estado socioeconómico, nivel de educación, migración, tabaquismo, consumo de alcohol y nivel actividad física. Resultados: La prevalencia del fenotipo DMO fue de 32,23% (IC95% 27,61-37,10). En el análisis multivariable, el sexo masculino mostró 39% menor probabilidad de presentar el fenotipo DMO (PRa: 0,610; IC95% 0,428-0,869; p=0,006), en comparación con el sexo femenino. Mientras que, pertenecer a los grupos de edad entre 45-59 años y de 60 años a más presentó 110,5% (PRa: 2,105; IC95% 1,484-2,988; p<0,001) y 97,6% (PRa: 1,976; IC95% 1,270-3,075; p=0,003), respectivamente, mayor probabilidad de presentar DMO, en comparación con el grupo de 29-44 años. Conclusiones: El pertenecer al sexo femenino y a los grupos de edad de 45 a 59 y 60 años a más, aumentaron la probabilidad de presentar el fenotipo DMO. Se recomienda la realización de futuros estudios con prospectivos y con un tamaño de muestra mayor para confirmar dichos hallazgos, así como la inclusión de nuevas variables.

Introduction: Patients with the lean metabolically obese (BMD) phenotype may present the same risk as the classic obese for developing long-term chronic diseases. However, the prevalence and the factors that are associated with it vary according to the population studied. Objective: to determine the prevalence and the factors associated with the BMD phenotype in Peru. Methods: Cross-sectional analytical study. Secondary analysis of the PERU MIGRANT study database. The associated factors that were considered were: age (30-44 years, 45-59 years, and 60 years and over), sex, socioeconomic status, level of education, migration, smoking, alcohol consumption and level of physical activity. Results: The prevalence of the BMD phenotype was 32.23% (95% CI 27.61-37.10). In the multivariate analysis, the male sex showed a 39% lower probability of presenting the BMD phenotype (PRa: 0.610; 95% CI 0.428-0.869; p=0.006), compared to the female sex. While belonging to the age groups between 45-59 years and 60 years and over presented 110.5% (PRa: 2.105; 95% CI 1.484-2.988; p<0.001) and 97.6% (PRa: 1.976; CI95% 1.270-3.075; p=0.003), respectively, greater probability of presenting BMD, compared to the group of 29-44 years. Conclusions: Belonging to the female sex and to the age groups of 45 to 59 and 60 years or more, increased the probability of presenting the BMD phenotype. Future prospective studies with a larger sample size are recommended to confirm these findings, as well as the inclusion of new variables.

Validez de contenido por juicio de expertos de un instrumento para medir conocimientos, actitudes y prácticas sobre el consumo de sal en la población peruana / Content validity by expert judgment of an instrument to measure knowledge, attitudes and practices about salt consumption in the peruvian population

Introducción: Ante el alto consumo de sal en la población, surge la necesidad de contar con una herramienta validada que mida los conocimientos, actitudes y prácticas del consumo de sal (CAP-sal). Objetivo: Validar el cuestionario de CAP-sal. Métodos: Estudio psicométrico de validez de contenido a través de juicio de expertos. Se contó un total de 5 médicos de diferentes especialidades. Para calcular el grado de acuerdo entre los jueces expertos se utilizó la V de Aiken Como criterio de decisión para mantener un ítem, se consideró un valor ≥ 0,7. Resultados: En relación a la claridad, se presentaron valores V superiores a 0,80, además, de un coeficiente de variación menor a 25%, por tanto, ninguno de los ítems fue eliminado. Con respecto a coherencia, presentaron un coeficiente de variación por encima del 20% y valores V superiores a 0,71, confirmando la decisión de no excluir alguno de ellos. Sobre la relevancia de los ítems, se evidenció también valores V superiores a 0,90 y tampoco presentó alguno un valor por debajo del crítico. Conclusiones:El cuestionario ha presentado suficientes evidencias de validez de contenido en claridad, coherencia y relevancia de los ítems a través de los análisis antes mencionados. Por eso mismo, debería ser utilizado para cuantificar el CAP-sal de diferentes grupos poblacionales del país.

Introduction: Given the high consumption of salt in the population, the need arises to have a validated tool that measures the knowledge, attitudes and practices of salt consumption (CAP-salt). Objective: To validate the questionnaire on CAP-salt. Methods: Psychometric study of content validity through expert judgment. A total of 5 physicians from different specialties were counted. To calculate the degree of agreement between the expert judges, Aiken's V was used. As a decision criterion to keep an item, a value ≥ 0.7 was considered. Results: In relation to clarity, V values greater than 0.80 were presented, in addition to a variation coefficient of less than 25%, therefore, none of the items was eliminated. Regarding coherence, they presented a coefficient of variation above 20% and V values greater than 0.71, confirming the decision not to exclude any of them. Regarding the relevance of the items, V values higher than 0.90 were also evidenced and neither did any of them present a value below the critical one. Conclusions: The questionnaire has presented sufficient evidence of content validity in terms of clarity, coherence and relevance of the items through the aforementioned analyses. For this reason, it should be used to quantify the KAP of different population groups in the country.

Evaluation of respiratory function by barometric whole-body plethysmography in healthy dogs.

The objective of the present study was to assess the validity of barometric whole-body plethysmography (BWBP), to establish reference values, and to standardise a bronchoprovocative test to investigate airway responsiveness using BWBP in healthy dogs. BWBP measurements were obtained from six healthy beagle dogs using different protocols: (1) during three consecutive periods (3.5min each) in two morning and two evening sessions; (2) before and after administration of two protocols of sedation; (3) before and after nebulisation of saline and increasing concentrations of carbachol and histamine both in conscious dogs and in dogs under both protocols of sedation. Enhanced pause (PENH) was used as index of bronchoconstriction. Basal BWBP measurements were also obtained in 22 healthy dogs of different breeds, age and weight. No significant influence of either time spent in the chamber or daytime was found for most respiratory variables but a significant dog effect was detected for most variables. A significant body weight effect was found on tidal volume and peak flow values (P<0.05). Response to carbachol was not reproducible and always associated with side effects. Nebulisation of histamine induced a significant increase in respiratory rate, peak expiratory flow, peak expiratory flow/peak inspiratory flow ratio and PENH (P<0.05). The response was reproduced in each dog at different concentrations of histamine. Sedation with acepromazine+buprenorphine had little influence on basal measurements and did not change the results of histamine challenge. It was concluded that BWBP is a safe, non invasive and reliable technique of investigation of lung function in dogs which provides new opportunities to characterise respiratory status, to evaluate airway hyperresponsiveness and to assess therapeutic interventions.
