Pseudotumor inflamatorioocular asociado a IgG4. Reporte de un caso / IgG4-Associated Ocular Inflammatory Pseudotumor. A Case Report

Resumen Introducción: El pseudotumor inflamatorio ocular asociado a IgG4 es un proceso inflamatorio no neoplásico y poco frecuente con una incidencia de 0.28-1.08 por cada 100,000 personas. El diagnóstico de esta patología es de exclusión debiendo cumplir criterios histopatológicos, agrandamiento de un órgano en específico y concentraciones serias de IgG4. El tratamiento tiene como objetivo evitar las complicaciones secundarias. Caso clínico: Mujer de 54 años de edad sin patologías previas referidas, acude refiriendo que 6 meses previos presenta de forma súbita y sin causa aparente prurito a nivel de globo ocular y párpado izquierdo, además de disminución de la agudeza visual y dolor retroocular, motivo por el que acude a valoración. Al examen físico presentó movimientos oculares normales, proptosis izquierda, dolor a la palpación, hiperemia subconjuntival, opacidad corneal, ausencia de reflejo rojo y más renitente a la presión el ojo izquierdo en relación con el contralateral. Tomografía cráneo-toraco-abdominal reporta a nivel ocular izquierdo imágenes sugestivas de melanoma coroideo sin hallazgos de actividad metastásica. Se realiza enucleación de ojo izquierdo. Se envía pieza a patología la cual reporta infiltrado difuso linfoplasmocítico positivas para IgG4. Conclusión: La enfermedad por IgG4 ocular es una patología muy infrecuente de clínica inespecífica y diagnóstico complejo. Sin embargo, un abordaje rápido y correcto es fundamental para evitar complicaciones.

Abstract Introduction: IgG4-associated ocular inflammatory pseudotumor is a rare, non-neoplastic inflammatory process with an incidence of 0.28-1.08 per 100,000 people. The diagnosis of this pathology is one of exclusion, having to meet histopathological criteria, enlargement of a specific organ, and serious concentrations of IgG4. Treatment aims to avoid secondary complications. Clinical case: A 54-year-old woman with no previous reported pathologies, reports that for the past 6 months she has itching at the level of the eyeball and the left eyelid, suddenly and without apparent cause, in addition to decreased visual acuity and retro-ocular pain; this is why she asked for the evaluation. The physical examination revealed normal eye movements, left proptosis, pain on palpation, subconjunctival hyperemia, corneal opacity, absence of red reflex, and the left eye being more resistant to pressure in relation to the contralateral eye. The cranio-thoraco-abdominal tomography reported images at the left ocular level that were suggestive of choroidal melanoma without findings of metastatic activity. Enucleation of the left eye was performed. The specimen was sent to pathology which reported diffuse lymphoplasmacytic infiltrate positive for IgG4. Conclusion: Ocular IgG4 disease is a very rare pathology with non-specific symptoms and complex diagnosis. However, a quick and correct approach is essential to avoid complications.

Trombosis venosa mesentérica y portal como causa infrecuente de obstrucción e isquemia intestinal en paciente joven. Reporte de caso / Mesenteric and Portal Venous Thrombosis as an infrequent cause of intestinal Obstruction and Ischemia in young patients. A case report

Resumen La isquemia mesentérica aguda se asocia a una mortalidad de entre el 50 y el 100%, la causa más rara de esta es la trombosis venosa de los vasos mesentéricos (5%) y portal (1%). Las manifestaciones clínicas son diversas, siendo el dolor abdominal el principal síntoma. La tomografía computarizada con contraste intravenoso en fase portal es la imagen más precisa para el diagnóstico. El tratamiento en fase aguda se basa en anticoagulación, fluidos intravenosos, antibióticos profilácticos, descanso intestinal y descompresión. La laparotomía de control de daños, incluida la resección intestinal y el abdomen abierto, pueden estar justificados en última instancia para pacientes con necrosis intestinal y sepsis. Caso clínico: Hombre de 35 años, sin antecedentes de importancia, solo tabaquismo desde hace 15 años. Refirió que 5 días previos comenzó a presentar dolor en el epigastrio tipo cólico, de intensidad moderada, posteriormente refirió que el dolor se generalizó y aumentó de intensidad, acompañado de náusea, vómito, intolerancia a la vía oral y alza térmica. Al examen físico tuvo datos de respuesta inflamatoria sistémica, estaba consciente y orientado, con abdomen doloroso a la palpación superficial y profunda a nivel generalizado, pero acentuado en el flanco derecho, rebote positivo con resistencia, timpanismo generalizado, peristalsis ausente. Se ingresó a quirófano a laparotomía exploradora, encontrando lesión a intestinal isquémica-necrótica a 190-240 cm del ángulo de Treitz, y 400 cc de líquido hemático; se realizó resección de la parte intestinal afectada, con entero-enteroanastomosis término-terminal manual. Se envió pieza a patología, y se reportó un proceso inflamatorio agudo con necrosis transmural y congestión vascular. Ante estos hallazgos se realizó angiotomografía abdominal que reportó defecto de llenado en la vena mesentérica superior, secundario a trombosis que se extendía hasta la confluencia y la vena porta. Conclusión: La trombosis venosa mesentérica y portal es una patología muy infrecuente en pacientes jóvenes sin factores de riesgo en los que se presenta dolor abdominal. El diagnóstico es complejo debido a que los datos clínicos y de laboratorio son poco específicos. Sin embargo, debemos tenerla en cuenta en el diagnóstico diferencial de etiologías de dolor abdominal.

Abstract Acute Mesenteric Ischemia is associated with a mortality rate between 50% and 100%; the rarest cause of this is venous thrombosis of the mesenteric (5%) and portal (1%) vessels. The clinical manifestations are diverse, with abdominal pain being the main symptom. Computed tomography with intravenous contrast in the portal phase is the most accurate image for diagnosis. Treatment in the acute phase is based on anticoagulation, intravenous fluids, prophylactic antibiotics, intestinal rest, and decompression. Damage control laparotomy, including bowel resection and open abdomen, may ultimately be warranted for patients with bowel necrosis and sepsis. Clinical case: 35-year-old man, with no significant history, only smoking for 15 years. For 5 days before, he reported crampy epigastric pain of moderate intensity. He subsequently reported that the pain became generalized and increased in intensity, accompanied by nausea, vomiting, oral intolerance, and temperature rise. The physical examination showed signs of a systemic inflammatory response, conscious and oriented, abdomen painful on superficial and deep palpation at a generalized level but accentuated on the right flank, positive rebound with resistance, generalized tympanism, absent peristalsis. The operating room was entered for exploratory laparotomy, finding an ischemic-necrotic intestinal lesion at 190 - 240 cm from the angle of Treitz, and 400cc of blood fluid. Resection of the affected intestinal part is performed, with entire manual terminal end anastomosis. The specimen was sent to pathology, reporting an acute inflammatory process with transmural necrosis and vascular congestion. Given these findings, abdominal CT angiography was performed, which reported a filling defect in the superior mesenteric vein, secondary to thrombosis that extended to the confluence and the portal vein. Conclusion: Mesenteric and portal venous thrombosis is a very rare pathology in young patients without risk factors in whom abdominal pain occurs. The diagnosis is complex because the clinical and laboratory data are not very specific. However, we must take it into account in the differential diagnosis of abdominal pain etiologies.

Observational analysis of clinical and pathological characteristics and their prognostic impact in Mexican patients with breast cancer: A multi-center study.

Breast cancer is the most incidental and deadly neoplasm worldwide; in Mexico, very few epidemiologic reports have analyzed the pathological features and its impact on their clinical outcome. Here, we studied the relation between pathological features and the clinical presentation at diagnosis and their impact on the overall and progression-free survival of patients with breast cancer. For this purpose, we collected 199 clinical records of female patients, aged at least 18 years old (y/o), with breast cancer diagnosis confirmed by biopsy. We excluded patients with incomplete or conflicting clinical records. Afterward, we performed an analysis of overall and progression-free survival and associated risks. Our results showed an average age at diagnosis of 52 y/o (24-85), the most common features were: upper outer quadrant tumor (32%), invasive ductal carcinoma (76.8%), moderately differentiated (44.3%), early clinical stages (40.8%), asymptomatic patients (47.8%), luminal A subtype (47.8%). Median overall survival was not reached, but median progression-free survival was 32.2 months (29.75-34.64, CI 95%) associated risk were: clinical stage (p < 0.0001) symptomatic presentation (p = 0.009) and histologic grade (p = 0.02). Therefore, we concluded that symptom presence at diagnosis impacts progression-free survival, and palpable symptoms are related to an increased risk for mortality.

Non-Targeted Self-Measured Blood Pressure and Hypertension Control in Public and Private Health Systems in Brazil

Abstract Background: It is estimated that more than 30% of the Brazilian population has systemic arterial hypertension (SAH), and mostly as an uncontrolled disease. The most recent Brazilian Guideline of Hypertension recommends the practice of self-measurement of blood pressure (BP) as one of the strategies for a better control of SAH, but there is no consensus about the efficiency of this tool. Objective: To assess the control of SAH and the practice of non-targeted self-measured BP (SMBP) among hypertensive users of the Unified Health System (SUS) and the Supplementary Network (SN). Methods: This is a cross-sectional, observational, analytical study, with a stratified probability sample. One thousand volunteers were investigated, being 500 from SUS and 500 from the SN. Uni and multivariate analyses were performed considering a 5% significance level. Results: Patients from SUS presented inferior sociodemographic data (schooling, social status) in relation to those of the SN (p < 0.001), and showed lower control of SAH (p = 0.014), as well as more visits to the emergency room in the past year due to hypertension (p = 0.002), and fewer regular appointments with the cardiologist (p = 0.004). SMBP was equally present in both assessed groups (p = 0.567), even though users of the SN have been more advised to not conduct such a practice (p = 0.002). SMBP (p < 0.001) was an independent factor for uncontrolled SAH both in SUS (OR = 3.424) and in the SN (OR = 3.474). Conclusion: Patients in SUS presented lower SAH control. The practice of SMBP, mostly practiced with an uncalibrated digital device, was equally present in both groups and became an independent factor of uncontrolled SAH.

Religiosity and Spirituality: The Relationship Between Psychosocial Factors and Cardiovascular Health

Abstract Background: Religiosity and Spirituality (R/S), despite being different entities, are multidimensional constructs, whose influence on cardiovascular health has been increasingly studied in recent decades. Objectives: To discriminate patients into subgroups according to R/S levels, in order to compare them regarding the distribution of cardiovascular comorbidities and clinical events. Methods: This is an observational, cross-sectional, analytical study. Two R/S scales were applied to a sample of patients seen at cardiology outpatient clinics. A cluster analysis was used to discriminate individuals into subgroups regarding R/S levels, which were subsequently compared regarding the frequencies of clinical variables related to cardiovascular health. A significance level of 5% was set for the statistical tests. Results: The sample included 237 patients with a mean age of 60.8 years (±10.7), of which 132 were female (55.7%). Cluster analysis (C) distinguished two groups: C1, with lower levels of R/S, and C2, with higher levels of R/S (p<0.001). C2 had a lower frequency of alcohol consumption (29.5% vs. 76.0%; p<0.001), smoking (12.9% vs. 51.0%; p<0.001), systemic arterial hypertension (SAH — 65.5% vs. 82.3%; p=0.005), dyslipidemia (58.3% vs. 77.1%; p=0.003), chronic coronary syndrome (36.7% vs. 58.3%; p=0.001), and prior cardiovascular events (15.8% vs. 36.5%; p<0.001) when compared to C1. There was also a higher frequency of females in C2 (82.0% vs. 17.7%; p<0.001). Conclusions: A better cardiovascular morbidity profile was observed in the group of patients with higher R/S levels, suggesting a probable positive relationship between R/S and cardiovascular health.

Actionable mutations in non-small cell lung cancer in patients at hospital de Especialidades Eugenio Espejo, Ecuador 2017-2020.

OBJECTIVES: Determine the frequency of actionable mutations in non-small cell lung cancer (NSCLC) and their correlation with overall survival (OS) and the site of metastases. METHODS: We performed a descriptive cross-sectional study at the Hospital de Especialidades Eugenio Espejo, Ecuador, between 2017 and 2020. Demographic, pathological, and molecular alterations in epidermal growth factor (EGFR), Anaplastic lymphoma kinase (ALK), ROS proto-oncogene 1 (ROS1), Programmed death-ligand 1 (PD-L1) expression, and clinical data detailed in patients' medical records with metastatic NSCLC were collected and analyzed. Seventy-nine stage IV patients had NSCLC; adenocarcinoma histology represents 56 (70.9%). The predominant mutation was in EGFR (22.8%); the most common variant was the deletion of exon 19 (72.2%). The most common metastatic site was in the contralateral lung (22.3%); however, this variable showed no significant correlation to the molecular markers (p=0.057). The overall survival (OS) and the status of molecular markers are not statistically significant (p=0.27). OS was better for non-mutated EGFR than for mutated EGFR (p=0.012). However, the frequency values are unrelated to contralateral lung metastasis or survival. CONCLUSIONS: Our frequency mutations are concordant with those found in other studies in Latin America. EGFR was the most common biomarker mutation, and there was a better OS in EGFR non-mutated patient.

Diferencia de niveles de dímero D ante la presencia de hipoxemia severa en pacientes con neumonía por SARS-CoV-2 ingresados a terapia intensiva / Difference in D-dimer levels in the presence of severe hypoxemia in patients with SARS-CoV-2 pneumonia admitted to therapy intensive / Diferença nos níveis de dímero D na presença de hipoxemia grave em pacientes com pneumonia por SARS-CoV-2 internados em terapia intensiva

Resumen Introducción: El SARS-CoV-2 se desconocía hasta el brote en Wuhan, China en diciembre de 2019, las características ultraestructurales de este virus con predisposición a receptores expresados en los neumocitos tipo II (CD209L y ECA2) resultan en daño alveolar difuso y un tercio de los pacientes con SARS-CoV-2 cumplen criterios de SIRA con hipoxemia severa. Tras el curso severo de la enfermedad y alta mortalidad se reportó en estudios la asociación del dímero D (DD) con casos graves y atribuyéndose al estado protrombótico de la enfermedad, contribuyendo directamente en ventilación mecánica prolongada y muerte. Objetivo principal: Determinar los diferentes niveles de dímero D ante la presencia de hipoxemia severa en pacientes con neumonía por SARS-CoV-2 ingresados en la terapia intensiva. Material y métodos: Estudio transversal comparativo retrospectivo unicéntrico, se revisaron expedientes de pacientes mayores de 18 años que ingresaron a la Unidad de Cuidados Intensivos con diagnóstico de neumonía por SARS-CoV-2; se tomaron en cuenta los valores de DD al ingreso, al séptimo día y la relación PaO2/FiO2 de gasometrías arteriales. Definimos hipoxemia severa PaO2/FiO2 menor de 150 mmHg y tras prueba U de Mann-Whitney se evaluaron niveles de DD, curva de ROC y AUC para punto de cohorte de DD y la asociación con terapia de aporte de oxígeno y su desenlace con OR e IC95%. Resultados: Se estudiaron expedientes de 82 pacientes, 81.7% presentó hipoxemia severa al ingreso, y 74.4% al séptimo día; se reportó una mediana de DD de 1,410 ng/mL con hipoxemia severa y al séptimo día 2,238 ng/mL (p = 0.001). Curva ROC encontró DD 1,500 ng/mL como punto de cohorte asociado a hipoxemia severa (AUC: 0.808, IC al 95% 0.706-0.910). En escalas pronósticas reportó mayor puntuación, APACHE II (24 pts, p = 0.036), SOFA (12 pts, p = 0.012), y SAPS II (67 pts, p ≤ 0.0001); así como en defunciones (81.6%, p ≤ 0.0001, OR 16.50 IC al 95% 5.472-49.80). Conclusión: Dímero D mayor y/o igual a 1,500 ng/mL se asocia con hipoxemia severa y con mayor mortalidad al séptimo día de estancia en UCI, indicándonos que el DD es un potencial marcador temprano y útil para guiar la terapéutica y evaluar el pronóstico del paciente.

Abstract Introduction: SARS-CoV-2 was unknown until the outbreak in Wuhan, China in December 2019, the ultra-structural characteristics of this virus with predisposition to receptors expressed in type II pneumocytes (CD209L and ECA2), results in diffuse alveolar damage and a third of the patients with SARS-CoV-2 meet criteria for SIRA with severe hypoxemia. After the severe course of the disease and high mortality, the association of DD with severe cases was reported in studies and attributed to the prothrombotic state of the disease, directly contributing to prolonged mechanical ventilation and death. Main objective: To determine the different levels of DD in the presence of severe hypoxemia in patients with SARS-CoV-2 pneumonia admitted to intensive care. Material and methods: Cross-sectional retrospective single-center study, records of patients older than 18 years who were admitted to the intensive care unit with a diagnosis of SARS-CoV-2 pneumonia were reviewed; DD values on admission, on the seventh day and the PaO2/FiO2 ratio of arterial blood gases were considered. We defined severe hypoxemia PaO2/FiO2 less than 150 mmHg and after the Mann-Whitney U test, DD levels, ROC curve and AUC were evaluated for the DD cohort point and the association with oxygen supply therapy and its outcome with OR and HF 95%. Results: Records of 82 patients were studied, 81.7% presented severe hypoxemia on admission, and 74.4% on the seventh day; A median DD of 1,410 ng/mL was reported with severe hypoxemia and 2,238 ng/mL on the seventh day (p = 0.001). ROC curve found DD 1,500 ng/mL as a cohort point associated with severe hypoxemia (AUC: 0.808, 95% CI 0.706-0.910). On prognostic scales I report a higher score, APACHE II (24 pts, p = 0.036), SOFA (12 pts, p = 0.012), and SAPS II (67 pts, p ≤ 0.0001); as well as in deaths (81.6%, p ≤ 0.0001, OR 16.50 95% CI 5.472-49.80). Conclusion: DD greater than and/or equal to 1,500 ng/mL is associated with severe hypoxemia and higher mortality on the seventh day of stay in the ICU, indicating that DD is a potential early and useful marker to guide the therapy and evaluate the prognosis of the patient.

Resumo Introdução: O SARS-CoV-2 era desconhecido até o surto em Wuhan, China, em dezembro de 2019, as características ultraestruturais desse vírus com predisposição a receptores expressos em pneumócitos tipo II (CD209L e ACE2), resultando em dano alveolar difuso e um terço dos pacientes com SARS-Cov-2 atendem aos critérios para SDRA com hipoxemia grave. Após o curso grave da doença e alta mortalidade, estudos relataram a associação do D-Di com casos graves e atribuindo-se ao estado pró-trombótico da doença, contribuindo diretamente para ventilação mecânica prolongada e óbito. Objetivo principal: Determinar os diferentes níveis de dímero-D na presença de hipoxemia grave em pacientes com pneumonia por SARS-CoV-2 internados em terapia intensiva. Material e métodos: Estudo transversal comparativo retrospectivo unicêntrico, foram revisados prontuários de pacientes maiores de 18 anos admitidos na unidade de terapia intensiva com diagnóstico de pneumonia por SARS-CoV-2; foram considerados os valores de D-Di na admissão, no sétimo dia e a relação PaO2/FiO2 da gasometria arterial. Definimos hipoxemia grave PaO2/FiO2 menor que 150 mmHg e após o teste U de Mann-Whitney, os níveis de D-Di, curva ROC e AUC foram avaliados para o ponto de coorte D-Di e a associação com oxigenoterapia e seu desfecho com OR e IC 95%. Resultados: Foram estudados prontuários de 82 pacientes, 81.7% com hipoxemia grave na admissão e 74.4% no sétimo dia; relatou-se um D-Di médio de 1,410 ng/mL com hipoxemia grave e 2,238 ng/mL no sétimo dia (p = 0.001). A curva ROC encontrou D-Di 1,500 ng/mL como um ponto de coorte associado à hipoxemia grave (AUC: 0.808, IC 95% 0.706-0.910). Em escalas de prognóstico, APACHE II (24 pontos, p = 0.036), SOFA (12 pts, p = 0.012) e SAPS II (67 pts, p ≤ 0.0001); bem como em óbitos (81.6%, p ≤ 0.0001, OR 16.50, IC 95% 5.472-49.80). Conclusão: O D-Di maior e/ou igual a 1,500 ng/ml está associada à hipoxemia grave e maior mortalidade no sétimo dia de internação na UTI, indicando que o D-Di é um potencial marcador precoce e útil para orientar a terapia e avaliar o prognóstico do paciente.

Infecção pelo sars-cov-2 e disfunção autonômica ­ labilidade pressórica na covid-19 / Sars-cov-2 infection and autonomic dysfunction - pressure liability at covid-19

Homem de 53 anos, hipertenso e portador de bronquite, admitido em um serviço de urgência no dia 15 de dezembro de 2020 devido sintomas gripais, febre e cefaleia iniciados há oito dias. Após constatação de acometimento pulmonar importante mediante tomografia computadorizada (TC) de tórax, sugestivo de infecção pelo vírus SARS-CoV2, o paciente foi internado em unidade de terapia intensiva. Foi intubado no décimo dia de internação, e, dois dias após, evoluiu com labilidade pressórica importante, recorrendo ao uso de noradrenalina e nitroprussiato, além de outros anti-hipertensivos, conforme a necessidade. O quadro predominante foi a hipertensão arterial sistêmica, manifestada principalmente com a mudança de decúbito, sendo o maior valor pressórico registrado de 240x90 mmHg. A disautonomia também se manifestou por ausência de dejeções, sudorese excessiva e espasmos musculares. A frequência cardíaca se manteve estável e dentro dos parâmetros de normalidade.A partir do trigésimo dia de internação, observou-se melhora progressiva do quadro e reestabelecimento da homeostase. Obteve alta após 59 dias de internação, sem sequelas significativas. A explicação mais razoável para o caso é o aumento da resistência vascular periférica, por ação da angiotensina II, associada à supressão do sistema parassimpático, o que explica, também, a incompetência do barorreflexo para compensação da frequência cardíaca. Adicionalmente, o paciente estava em uso de carvedilol. Este caso enfatiza o desafio diagnóstico precoce da disautonomia em pacientes críticos, devido a carência de ferramentas adequadas para uso na prática cotidiana. A estimulação vagal pode constituir opção terapêutica eficaz, mas carece de mais estudos

A 53-year-old male, hypertensive and with bronchitis, was admitted to the emergency department on December 15, 2020 due to flu-like symptoms, fever and headache that started eight days ago. After finding significant lung involvement by chest computed tomography (CT) suggestive of SARS-CoV2 virus infection, the patient was admitted to the intensive care unit. He was intubated on the tenth day of hospitalization, and, 2 days later, he evolved with significant pressure lability, using norepinephrine and nitroprusside, in addition to other antihypertensive drugs, as needed. The predominant state was hypertension, expressed mainly when there is interference from the patient's position in bed. The highest pressure value recorded was 240x90 mmHg. Dysautonomy was also manifested by the absence of stools, excessive sweating and muscle spasms. Heart rate remains stable and within normal limits. From the thirtieth day of hospitalization onwards, there was an evolution with progressive improvement and restoration of homeostasis. He was discharged after 59 days of hospitalization, without sequelae. The most reasonable explanation for the case is the increase in peripheral vascular resistance, due to the action of angiotensin II, associated with the suppression of the parasympathetic system, which also explains the incompetence of the baroreflex to compensate the heart rate. Additionally, the patient was using carvedilol. This case emphasizes the importance of tools that early identify dysautonomy, prepare the team. Vagal stimulation can be an effective therapeutic option, but further studies are needed

Uso do SAPS 3 no escore NUTrition RIsk in the Critically ill modificado tem precisão preditiva comparável ao uso do APACHE II como marcador de gravidade / SAPS 3 in the modified NUTrition RIsk in the Critically ill score has comparable predictive accuracy to APACHE II as a severity marker

RESUMO Objetivo: Avaliar o Simplified Acute Physiology Score 3 (SAPS 3) como substituto do Acute Physiology and Chronic Health Evaluation II (APACHE II) como marcador de gravidade na versão modificada do escore NUTrition RIsk in the Critically ill (mNUTRIC; sem interleucina 6), com base em uma análise de sua capacidade discriminativa para predição de mortalidade hospitalar. Métodos: Este estudo de coorte retrospectiva avaliou 1.516 pacientes adultos internados em uma unidade de terapia intensiva de um hospital geral privado entre abril de 2017 e janeiro de 2018. A avaliação de desempenho incluiu as análises Kappa de Fleiss e correlação de Pearson. A capacidade discriminativa para estimar a mortalidade hospitalar foi avaliada com a curva Característica de Operação do Receptor. Resultados: A amostra foi dividida aleatoriamente em dois terços para o desenvolvimento do modelo (n = 1.025; idade 72 [57 - 83]; 52,4% masculino) e um terço para avaliação do desempenho (n = 490; idade 72 [57 - 83]; 50,8 % masculino). A concordância com o mNUTRIC foi Kappa de 0,563 (p < 0,001), e a correlação entre os instrumentos foi correlação de Pearson de 0,804 (p < 0,001). A ferramenta mostrou bom desempenho para prever a mortalidade hospitalar (área sob a curva de 0,825 [0,787 - 0,863] p < 0,001). Conclusão: A substituição do APACHE II pelo SAPS 3 como marcador de gravidade no escore mNUTRIC mostrou bom desempenho para predizer a mortalidade hospitalar. Esses dados fornecem a primeira evidência sobre a validade da substituição do APACHE II pelo SAPS 3 no mNUTRIC como marcador de gravidade. São necessários estudos multicêntricos e análises adicionais dos parâmetros de adequação nutricional.

ABSTRACT Objective: To evaluate the substitution of Acute Physiology and Chronic Health Evaluation II (APACHE II) by Simplified Acute Physiology Score 3 (SAPS 3) as a severity marker in the modified version of the NUTrition RIsk in the Critically ill score (mNUTRIC); without interleukin 6) based on an analysis of its discriminative ability for in-hospital mortality prediction. Methods: This retrospective cohort study evaluated 1,516 adult patients admitted to an intensive care unit of a private general hospital from April 2017 to January 2018. Performance evaluation included Fleiss' Kappa and Pearson correlation analysis. The discriminative ability for estimating in-hospital mortality was assessed with the Receiver Operating Characteristic curve. Results: The sample was randomly divided into two-thirds for model development (n = 1,025; age 72 [57 - 83]; 52.4% male) and one-third for performance evaluation (n = 490; age 72 [57 - 83]; 50.8% male). The agreement with mNUTRIC was Kappa of 0.563 (p < 0.001), and the correlation between the instruments was Pearson correlation of 0.804 (p < 0.001). The tool showed good performance in predicting in-hospital mortality (area under the curve 0.825 [0.787 - 0.863] p < 0.001). Conclusion: The substitution of APACHE II by SAPS 3 as a severity marker in the mNUTRIC score showed good performance in predicting in-hospital mortality. These data provide the first evidence regarding the validity of the substitution of APACHE II by SAPS 3 in the mNUTRIC as a marker of severity. Multicentric studies and additional analyses of nutritional adequacy parameters are required.

[Body composition assessment before and after weight loss following a Roux-en-Y gastric bypass. Are bioimpedanciometry estimations reliable?] / Evaluación de la composicion corporal antes y después de la reducción de peso con baipás gastrico en Y de Roux. ¿Son confiables las mediciones de la bioimpedanciometría?

INTRODUCTION: Introduction: in patients with severe and morbid obesity it has been observed that bioimpedance (BIA) assessment generates an underestimation of fat mass (FM) and weight loss as FM after bariatric surgery, overestimating the loss of fat-free mass (FFM) and muscle mass. Objective: to evaluate the reliability of bioelectrical impedance analysis (BIA) to estimate total body water (TBW), fat-free mass (FFM), fat mass (FM), and its changes after 6 months of a Roux-en-Y gastric bypass (RYGBP), in patients with severe and morbid obesity. Methods: thirty-six patients approved for RYGBP were prospectively studied. TBW was measured by deuterium (D), and FM and FFM were calculated. A dual-frequency BIA device (5 and 200 kHz) (Bodystat Dualscan®) was used to estimate FM, FFM, TBW, extracellular water (ECW), intracellular water (ICW), and ECW/ICW ratio. Results: before RYGBP, BIA overestimated TBW by 2.6 ± 4.3 L (p = 0.002) and FFM by 3.5 ± 5.7 kg (p = 0.002), and underestimated FM% by 2.98 ± 4.7% (p = 0.002). The ECW/ICW ratio showed a significant and positive correlation with the difference BIA-D for FFM (r = 0.49; p = 0.002). After surgery, the differences between BIA and D were not significant, and the estimation error of FFM did not correlate with the ECW/ICW ratio. Conclusions: BIA generates an underestimation of FM as reported in patients with severe and morbid obesity, which is attenuated after weight reduction, underestimating weight loss as FM and overestimating FFM loss. Future research may assess whether these errors are reproduced by other BIA devices.

INTRODUCCIÓN: Introducción: en pacientes con obesidad severa y mórbida se ha observado que la evaluación por bioimpedanciometría (BIA) genera una subestimación de la masa grasa (MG) y del peso perdido como MG después de la cirugía bariátrica, sobreestimándose la pérdida de masa libre de grasa (MLG) y la masa muscular. Objetivo: evaluar la confiabilidad de la BIA para estimar el agua corporal total (ACT), la MLG, la MG y sus cambios después de 6 meses de un baipás gástrico en Y de Roux (BPGYR) en pacientes con obesidad severa y mórbida. Métodos: 36 adultos con indicación de BPGYR se estudiaron prospectivamente. Se midió el ACT por deuterio (D) y se calcularon la MLG y MG. Con BIA de doble frecuencia (5 y 200 kHz) (Bodystat Dualscan®) se estimaron la MG, la MLG, el ACT, el agua extracelular (AEC), el agua intracelular (AIC) y la relación AEC/AIC. Resultados: antes del BPGYR, la BIA sobreestimó el ACT en 2,6 ± 4,3 L (p = 0,002) y la MLG en 3,5 ± 5,7 kg (p = 0,002), y subestimó el %MG en 2,98 ± 4,7% (p = 0,002). La relación AEC/AIC mostró una correlación positiva con la sobreestimación de la MLG por BIA (r = 0,49; p = 0,002). Después de la cirugía, las diferencias entre BIA y D no fueron significativas y el error de estimación de la MLG no se correlacionó con la relación AEC/AIC. Conclusiones: la BIA genera una subestimación de la MG como la reportada, la cual se atenúa después de la reducción de peso, subestimando el peso perdido como MG y sobreestimando la pérdida de MLG. Futuras investigaciones podrán evaluar si estos errores se reproducen con otros equipos de BIA.

Nutritional profile and mortality in patients undergoing percutaneous endoscopic gastrostomy.

INTRODUCTION: Background: malnutrition is a common problem in hospitalized patients, being associated with increased morbidity, mortality and costs. Multiple factors contribute to a deficient nutritional status, making malnutrition the cause or consequence of severe diseases. Percutaneous endoscopic gastrostomy (PEG) is a minimally invasive procedure indicated for long-term administration of enteral nutrition in patients with limited ability for oral intake who have an intact, functional gastrointestinal tract. The aim of this study was to determine the profile of patients undergoing PEG in a tertiary hospital in southern Brazil. Methods: single-center retrospective study of all patients who underwent PEG from January 1st to December 31st, 2016, in a private tertiary hospital located in southern Brazil. Data were collected retrospectively from the patients' medical records, including nutritional status, indications, complications and outcomes. Results: one hundred and thirty-three patients underwent PEG at our institution and were eligible for inclusion in the study. Median patient age was 82 years, and 57.9% were females. The main indication for PEG was dementia syndrome, followed by stroke. As much as 68.4% were diagnosed as severely malnourished and 23.0% had procedure-related complications. Conclusions: PEG tubes are being increasingly used for enteral nutrition in patients with dysphagia or inability to maintain adequate nutritional intake. The findings of the present study highlight the importance of regular nutritional risk screening by a multidisciplinary team, paying special attention to the patient's nutritional status and conditions that may place the patient at risk of developing dysphagia, with the implementation of measures to minimize malnutrition in hospitalized patients.

INTRODUCCIÓN: Introducción: la desnutrición es común en pacientes hospitalizados y se está convirtiendo en causa o consecuencia de enfermedades graves, asociándose a morbilidad, mortalidad y costos aumentados. Múltiples factores contribuyen a un estado nutricional deficiente. La gastrostomía endoscópica percutánea (PEG) es un procedimiento mínimamente invasivo para la administración de nutrición enteral en pacientes con capacidad limitada de ingesta oral que tengan el tracto gastrointestinal intacto y funcional. El objetivo de este estudio fue determinar el perfil de pacientes sometidos a PEG en un hospital terciario del sur de Brasil. Métodos: estudio retrospectivo unicéntrico de todos los pacientes sometidos a PEG del 1 de enero al 31 de diciembre de 2016 en un hospital terciario privado del sur de Brasil. Se recolectaron los datos retrospectivamente en los registros médicos, incluyendo estado nutricional, indicaciones, complicaciones y evolución. Resultados: ciento treinta y tres pacientes se sometieron a PEG en nuestra institución y fueron elegibles para el estudio. La edad mediana fue de 82 años y el 57,9% eran mujeres. Las principales indicaciones para PEG fueron demencia y accidente cerebrovascular. El 68,4% fueron diagnosticados con desnutrición grave y el 23,0% presentaron complicaciones relacionadas al procedimiento. Conclusiones: se utilizan cada vez más tubos de PEG para nutrición enteral en pacientes disfágicos o incapaces de mantener una ingesta nutricional adecuada. Nuestros hallazgos señalan la importancia del cribado para riesgo nutricional por un equipo multidisciplinario, con atención especial al estado nutricional del paciente y a condiciones que pueden ponerlo en riesgo para disfagia y la implementación de medidas para minimizar la desnutrición.

Doença crítica crônica: estamos salvando ou criando vítimas? / Chronic critical illness: are we saving patients or creating victims?

RESUMO Os avanços tecnológicos que permitem dar suporte às disfunções de órgãos levaram a um aumento nas taxas de sobrevivência para a maioria dos pacientes críticos. Alguns destes pacientes sobrevivem à condição crítica inicial, porém continuam a sofrer com disfunções de órgãos e permanecem em estado inflamatório por longos períodos. Este grupo de pacientes críticos foi descrito desde os anos 1980 e teve diferentes critérios diagnósticos ao longo dos anos. Sabe-se que estes pacientes têm longas permanências no hospital, sofrem importantes alterações do metabolismo muscular e ósseo, apresentam imunodeficiência, consomem quantias substanciais de recursos de saúde, têm reduzida capacidade funcional e cognitiva após a alta, demandam uma considerável carga de trabalho para seus cuidadores, e apresentam elevadas taxas de mortalidade em longo prazo. O objetivo desta revisão foi apresentar as evidências atuais, em termos de definição, fisiopatologia, manifestações clínicas, tratamento e prognóstico da doença crítica persistente.

ABSTRACT The technological advancements that allow support for organ dysfunction have led to an increase in survival rates for the most critically ill patients. Some of these patients survive the initial acute critical condition but continue to suffer from organ dysfunction and remain in an inflammatory state for long periods of time. This group of critically ill patients has been described since the 1980s and has had different diagnostic criteria over the years. These patients are known to have lengthy hospital stays, undergo significant alterations in muscle and bone metabolism, show immunodeficiency, consume substantial health resources, have reduced functional and cognitive capacity after discharge, create a sizable workload for caregivers, and present high long-term mortality rates. The aim of this review is to report on the most current evidence in terms of the definition, pathophysiology, clinical manifestations, treatment, and prognosis of persistent critical illness.

Nivel de intensidad de las principales actividades físicas de escolares chilenos: determinación por acelerometría / Intensity level of the main physical activities of Chilean school children: determination by accelerometry

The aim of this study was to determine the intensity level of different specific activities of chilean school children by accelerometric values. With this objective, 80 children aged 10 to 12 years (39 boys, 41 girls) filled a diary of their activities in a structured format and simultaneously weard an accelerometer for one to three days. The activities of every subject were expressed in counts per minute (cpm). The levels of physical activity (PA). Were classified as sedentary PA / light PA / moderate PA and vigorous PA. Results: 26 different activities were documented. In most of them the difference between boys and girls was weak and no significant. The only vigorous PA was to run. In category "moderate PA" the cpm of plays outdoor was significantly less than those of sports and school gymnastic (p 0,007)- These results can serve as guiding for establish a scale of values for global evaluation of PA in children schoolers.

El propósito del presente trabajo fue determinar por valores acelerométricos el nivel de intensidad de diferentes actividades específicas de niños escolares chilenos. Con este objetivo, 80 niños de 10 a 12 años (39 varones y 41 niñas) llevaron un diario de actividades en un formato estructurado y simultáneamente un acelerómetro por uno a tres días. En cada sujeto las actividades se expresaron en cuentas por minuto (cpm). Los niveles respectivos de actividad física (AF) fueron clasificados en: AF sedentaria/ AF leve / AF moderada / AF vigorosa. Resultados: 26 actividades diferentes fueron documentadas. En la mayoría de ellas la diferencia entre niños y niñas fue leve y no significativa. La única AF vigorosa fue correr. En la categoría “AF moderada” los cpm de los juegos al aire libre fueron significativamente más bajos que las de los deportes y educación física escolar (p 0,007). Estos resultados pueden servir de guía para establecer una escala de valores en la evaluación global de la AF de niños chilenos.

Parámetros de composición corporal en pacientes VIH mediante el análisis de la biompedancia eléctrica

Se han descrito cambios en la composición corporal en pacientes VIH mediante el análisis de la bioimpedancia eléctrica (ABE). Hay pocos estudios que describan estos cambios en la composición corporal en pacientes VIH en Venezuela. Objetivo: Conocer cuáles son las características de la composición corporal de los pacientes VIH (Hospitalizados y Ambulatorios), período enero - agosto 2015. Materiales y Métodos: Estudio descriptivo - transversal. Tres grupos: Hospitalizados: pacVIH-h (n=22), Ambulatorio: pacVIH-a (n=47) y No VIH: Control (n=28). Se registraron género, peso, talla y LCD4+. Mediante ABE se obtuvo: Masa grasa (MG), Tejido adiposo abdominal (TAA), Agua corporal total (ACT), Agua intracelular (AIC), Agua extracelular (AEC), Masa celular corporal (MCC), Masa libre de grasa (MLG), Potasio corporal total (KCT), Ángulo de Fase (AF). Resultados: Peso, IMC, LCD4+ fue menor en pacVIH-h. La MG y TAA fue menor en grupos de pacientes VIH con respecto al Control. No hubo diferencias en Agua Corporal. MMC fue menor en pacVIH-a. AF fue menor en pacVIH. Una correlación significativa entre MG y TAA, y LCD4+. Conclusión: Este estudio ha permitido exponer y reconocer los aspectos relacionados con los cambios en la composición corporal que ocurren en el paciente VIH adulto. La relación entre el compartimento graso y CD4+ permitiría explorar el papel del tejido adiposo en la reconstitución inmune.

Body composition in HIV patients have been assessed previously using bioelectrical impedance analysis (BIA). Lack of studies that describes changes in body composition in Venezuelan HIV patients. Objective: To assess body composition characteristic of HIV patients (hospitalized, ambulatory) , period January-August 2015. Methods: Descriptive-transversal study. Three groups: hospitalized: HIV-h (n=22), ambulatory: HIV-a (n=47) and Control (n=28). Gender, weight, height, CD4+ were measured. By BIA: Fat Mass (FM), Abdominal Adipose Tissue (AAT), Total body water (TBW), Intracellular water (ICW), Extracellular water (ECW), Body cell mass (BCM),Free Fat Mass (FFM), Total body potassium (TBK), Phase angle (PA). Results: Weight, BMI, CD4+ were lower in HIV-h. FM and AAT were lower in HIV patients. Water compartment showed no differences. BCM were lower in HIV-a. PA was lower in HIV patients. Significant relationship between FM, ATT and CD4+ was found. Conclusions: This study let us expose and recognize body composition changes that occur in HIV patients. Relationship between FAT, AAT and CD4+ can let us explore the possible role of adipose tissue in immune reconstitution.

[EFFECT OF OVERWEIGHT AND OBESITY ON THE EQUILIBRIUM TIME, BUT NO IN THE TOTAL BODY WATER AND BODY COMPOSITION COMPARTMENTS IN WOMEN SUBJECTS OVER 60 YEARS OF AGE]. / INFLUENCIA DEL SOBREPESO Y LA OBESIDAD SOBRE EL TIEMPO DE EQUILIBRIO DEL DEUTERIO, PERO NO EN EL AGUA CORPORAL TOTAL Y LA COMPOSICIÓN CORPORAL EN MUJERES MAYORES DE 60 AÑOS.

INTRODUCTION: aging and obesity cause changes in water exchange rate, which could affect the equilibrium time of deuterium oxide (2H2O). OBJECTIVE: to assess the effect of overweight and obesity on the equilibrium time of the stable isotope deuterium in saliva samples of older adults. METHODS: a sample of 18 women over 63 years with a body mass index (BMI) of 20.8 to 40.5 kg/m2 were included. A basal saliva sample was took and immediately a dose of 30 g of 2H2O was administered orally. Saliva samples at 2, 2.5, 3, 3.5 and 4 hours post-dose were taken. Deuterium in saliva samples were analyzed by Fourier Transform Infrared spectroscopy technique. RESULTS: the average in equilibrium time (plateau) in women of normal BMI (18.5-24.9 kg/m2) was 3.6 ± 0.2 hours, which was statistically different to those obtained in the group with overweight (25-29.9 kg/m2) and obese (>30 kg/m2) of 2.9 ± 0.4 hours and 2.8 ± 0.4 hours, respectively (p0.05). CONCLUSION: obesity had an effect on the equilibrium times; however, did not affect the calculation of total body water and body composition in this older women adult group.

Introducción: el envejecimiento y la obesidad producen cambios en la tasa de recambio de agua, lo que podría afectar al tiempo de equilibrio del óxido de deuterio (2H2O). Objetivo: se evaluó el efecto del sobrepeso y la obesidad sobre el tiempo de equilibrio del isótopo estable de deuterio en muestras de saliva de adultos mayores. Métodos: se incluyeron 18 mujeres entre 63 y 80 años con un índice de masa corporal (IMC) de 20,8 a 40,5 kg/m2. Después de la toma de una muestra de saliva basal se administró una dosis vía oral de 30 g de 2H2O. Se tomaron muestras de saliva a las 2, 2,5, 3, 3,5 y 4 horas post-dosis, las cuales fueron analizadas mediante espectrometría infrarroja con transformada de Fourier. Resultados: el tiempo de equilibrio (plateau) promedio en las mujeres con un IMC normal (18,5-24,9 kg/m2) fue de 3,6 ± 0,2 horas, el cual fue diferente estadísticamente al obtenido en el grupo con sobrepeso (25-29,9 kg/m2) y obesidad (>30 kg/m2) de 2,9 ± 0,4 horas y 2,8 ± 0,4 horas, respectivamente (p0,05). Conclusión: se encontró un efecto de la obesidad sobre el tiempo de equilibrio; sin embargo, no afectó al cálculo del agua corporal total y a la composición corporal en este grupo etario.

MOTOR SKILLS AND NUTRITIONAL STATUS OUTCOMES FROM A PHYSICAL ACTIVITY INTERVENTION IN SHORT BREAKS ON PRESCHOOL CHILDREN CONDUCTED BY THEIR EDUCATORS: A PILOT STUDY.

INTRODUCTION: childhood obesity is a worldwide health concern. For this issue different intervention have being planned to increase physical activity patterns and reduce the excess of weight in children with limited or no success. OBJECTIVE: the aim of this study is to evaluate the results of a pilot intervention consisting in three 15-minute breaks conducted by educators and supervised by physical education teachers on motor skills and nutritional status in preschool children. METHODS: sample was 70 preschool children (32 boys and 38 girls), age 4 ± 0,6 years. The physical activity classes were performed three times a week, 45 minutes daily, distributed in three 15 minutes breaks. The circuits were planned to have; jumps, sprints, carrying medicinal balls, gallops and crawling. Motor skill tests that were performed Standing long jump (SLJ) and Twelve meter run. RESULTS: with the intervention no significant differences in nutritional status where found on mean Z score (boys p = 0.49, girls p = 0.77). An increment on weight and height was fount after the intervention (p < 0.0001). Regarding the 12 meter run test, we found significant changes after the intervention when we normalize by weight in boys (p = 0.002) and girls (p < 0.0001). Our results have shown than boys significantly increased their SLJ and SLJ normalized by weight (p < 0.0001); a similar result was found in girls after the intervention (p < 0.0001) suggesting the increment of power independent of weight gain. CONCLUSIONS: in conclusion, this pilot study found that an intervention with more intense activities in small breaks (15 minutes), and guided by the educators could improve essential motor skills (running and jumping) in preschool children of a semi-rural sector independent of nutritional status. This gaining in motor skills is the first step to increase physical activity levels in preschool children.

Introducción: la obesidad infantil es ya un problema de salud pública. Para su disminución, han sido planteadas diferentes estrategias con el fin de aumentar la actividad física y con ello reducir la ganancia de peso en niños; estas estrategias se han llevado a cabo con un éxito limitado. Objetivo: el objetivo de este estudio es evaluar los resultados de una intervención piloto, la cual consiste en tres recreos de 15 minutos tres veces por semana conducidos por las educadoras y guiados por educadores físicos en los patrones motores y el estado nutricional de niños preescolares. Métodos: la muestra consta de 70 niños preescolares (32 niños y 38 niñas), edad 4 ± 0.6. Las clases de educación física fueron llevadas a cabo tres veces por semana en recreos de 15 minutos. Se plantearon circuitos, los cuales contenían saltos, gateo, galopes, carreras, carga y manipulación de balones medicinales. Las pruebas motoras evaluadas fueron el salto horizontal y la carrera de 12 metros. Resultados: con la intervención no se encontraron diferencias significativas en el estado nutricional (media Z score niños p = 0,49, media Z score niñas p = 0,77). Sí se encontró un aumento significativo en el peso (p < 0,0001) y la talla ( p < 0,0001) tanto en niños como en niñas al término de la intervención. En cuanto a las pruebas motoras, la carrera de 12 metros ajustada al peso tuvo cambios significativos en niños (p = 0,002) y en niñas ( p < 0,0001); mientras que el salto horizontal mejoró en ambos grupos tras la intervención (p < 0,0001). Cuando se ajustaron las pruebas motoras por estado nutricional, se encontraron cambios significativos tanto en la carrera de 12 metros en los niños con sobrepeso (p = 0,008) como en el salto horizontal/talla (p < 0,0001), lo que sugiere el incremento de la potencia independientemente del aumento de peso observado. Conclusión: este estudio piloto encontró que una intervención con actividades más intensas en pequeños recreos guiadas por educadoras pueden incrementar los patrones motores básicos en niños preescolares, independientemente del incremento de peso. Esta ganancia en los patrones motores es el primer paso para el incremento de los niveles de actividad física en niños preescolares.

Despite chemical and physical vector control strategies, persistent infestations of Triatoma sordida have been reported in a large part of Minas Gerais, Brazil, and the cause for this is little investigated. We aimed to characterize the deltamethrin toxicological profile in peridomestic T. sordidapopulations from Triângulo Mineiro area of Minas Gerais.

Pilot nutrition and physical activity intervention for preschool children attending daycare centres (JUNJI): primary and secondary outcomes.

INTRODUCTION: A pilot intervention was conducted to promote physical activity and nutrition in public preschool education (near half a million children in Chile), in order to prevent obesity. OBJECTIVE: To assess the primary (body fat) and secondary outcomes (physical activity and energy intake) of a nutrition and physical activity pilot intervention for preschool children, attending day care centres. METHODS: A pilot intervention in six day care centres selected at random (n = 530), in 4-5 years old preschool children, Santiago, Chile intending to: provide nutritional and physical activity education to educators and health promotion activities for the family, which in turn, will affect the primary (body fat), and secondary outcomes (physical activity pattern and energy food intake) were measured in a representative subsample of 120 intervened and 145 controls children. RESULTS: In relation to secondary outcomes monitoring, moderate-vigorous activity was duplicated in the intervention group (+5.4% and +4.7%, respectively), in both obese and eutrophic children. Energy intake decreased in 11.7% in obese and 7.5% in eutrophic children. Dietary fat intake was reduced (-11 g in obese and -8.4 g in eutrophic children). Intervened obese children reduced body fat in 1.5%, meanwhile in control obese children, body fat increased 1.3% (p < 0.01). CONCLUSIONS: The pilot intervention demonstrated the feasibility to influence dietary risk factors and physical activity at the day care centres and families. Therefore, the implementation of the validated intervention program will be tested in different weather conditions, to prevent unhealthy habits in preschool children and their families.

Introducción: Intervención piloto en nutrición y actividad física para prevenir obesidad en la educación preescolar (cerca de medio millón de niños en Chile). Objetivo: Evaluar los resultados primarios (grasa corporal) y secundarios (actividad física e ingesta energética) de una intervención piloto para niños/as asistentes a guarderías infantiles. Métodos: Intervención piloto en seis guarderías seleccionadas al azar (n = 530 preescolares), 4-5 años en Santiago de Chile, con el objeto de: a) proporcionar educación en nutrición y actividad física para los educadores; b) actividades de promoción de la salud para la familia. El objetivo primario (grasa corporal), y los resultados secundarios (patrón de actividad física y la ingesta energética) se midieron en 265 preescolares (120 intervenidos y 145 niños controles). Resultados: La actividad física moderada- intensa se duplicó en los intervenidos (+5,4% y +4,7%, respectivamente), tanto en niños obesos y eutróficos. La ingesta energética se redujo en 11,7% en obesos y 7,5% en los eutróficos y la de grasa en (-11 g en obesos y -8,4 g en niños eutróficos). Los niños obesos intervenidos redujeron la grasa corporal en 1,5%, mientras que en los niños controles obesos, se incrementó 1,3% (p < 0,01). Conclusiones: La intervención piloto demostró la viabilidad de influir en los factores de riesgo dietarios y de actividad física en las guarderías y en las familias. Por lo tanto, la ejecución del proyecto piloto se pondrá a prueba en diferentes condiciones climáticas, para prevenir hábitos no saludables en los preescolares y sus familias.

Variabilidad de la actividad física en niños chilenos de 4 a 10 años: estudio por acelerometría / Variability of physical activity in 4 to 10-year-old children: a study by accelerometry

Introducción. Frente a los populares cuestionarios, la acelerometría entrega una información más confiable de la actividad física. Así, el objetivo ha sido documentar la variabilidad de la actividad física de niños chilenos en relación con edad, sexo, estado nutricional y días de la semana, y determinar cuántos de ellos cumplen con la recomendación de tener actividad física moderada y vigorosa por más de una hora diaria. Población y métodos. Ciento nueve (109) escolares de 4-10 años de edad (67 niños, 42 niñas) llevaron un acelerómetro durante 2, 3 o 4 días consecutivos. Treinta eran obesos (IMC>P95 por edad y sexo). En cada sujeto, los niveles de actividad física fueron expresados en cuentas por minuto (cpm) y promedios (DE) de cpm/hora. La actividad física moderada y vigorosa se definió por la suma diaria de cpm>900. Resultados. La actividad física diurna tuvo un promedio de 21 697 (662) cmp/hora con variabilidad considerable de un niño a otro, y de un momento a otro del día en un mismo niño. Las cpm/hora individuales estaban significativamente asociadas con actividad física moderada y vigorosa (R= 0,954). Se encontraron diferencias entre niñas y niños (p <0,01) y entre obesos y no obesos (p <0,01). No hubo diferencia entre 9 años (p= 0,12). Entre semana y fin de semana hubo una leve diferencia. Cincuenta y seis de 67 (83,6%) niños y 24 de 42 (57,1%) niñas cumplieron con la recomendación de realizar actividad física moderada y vigorosa por más de 60 minutos diarios. Conclusión. Existe déficit de actividad física en escolares chilenos menores de 10 años, particularmente en niñas y en obesos.

Introduction. When compared to popular questionnaires, accelerometry provides more reliable information regarding physical activity. Thus, the objective has been to document the variability of physical activity in Chilean children in relation to age, gender, nutritional status and days of the week, and to determine how many of them meet the recommendation for moderate to vigorous physical activity for more than an hour a day. Population and methods. One hundred and nine (109) school children aged 4-10 (67 boys, 42 girls) wore an accelerometer for 2, 3 or 4 consecutive days. Of them, 30 were obese (BMI>95th percentile by age and gender). In each subject, levels of physical activity were expressed in counts per minute (cpm) and means (SD) of cpm/hour. Moderate to vigorous physical activity was defined by the daily sum of cpm>900. Results. Daytime physical activity had a mean of 21,697 (662) cpm/hour with considerable variation from one child to another, and from one time of the day to another in the same child. Individual cpm/hour was significantly associated to moderate to vigorous physical activity (R = 0.954). Differences were found between girls and boys (p < 0.01) and between obese and non-obese children (p < 0.01). There were no differences between children 9 years (p = 0.12). There was a slight difference between weekdays and weekends. Fifty-six (56) of 67 boys (83.6%) and 24 of 42 girls (57.1%) met the recommendation for moderate to vigorous physical activity for more than 60 minutes a day. Conclusion. There is a physical activity defcit in Chilean school children under 10 years, particularly in girls and obese kids.
