Linfocitosis monoclonal de células B en familiares de pacientes colombianos con síndromes linfoproliferativos crónicos B

Introducción. La linfocitosis monoclonal de células B, generalmente, precede la leucemia linfocítica crónica y afecta alrededor del 12 % de la población adulta sana. Esta frecuencia se incrementa en familiares de pacientes con síndromes linfoproliferativos crónicos de células B. Objetivo. Determinar la frecuencia de linfocitosis monoclonal B en familiares de pacientes con síndromes linfoproliferativos crónicos B, sus características inmunofenotípicas y citogenéticas, posible relación con agentes infecciosos, y seguimiento a corto plazo de población colombiana. Materiales y métodos. Se estudiaron 50 adultos sanos con antecedentes familiares de síndromes linfoproliferativos crónicos de célula B, empleando citometría de flujo multiparamétrica, pruebas citogenéticas y serológicas, encuesta de hábitos de vida y seguimiento a dos años. Resultados. La frecuencia encontrada de linfocitosis monoclonal B fue del 8 %, con predominio del sexo femenino y edad avanzada, incrementándose al 12,5 % en individuos con antecedentes familiares de leucemia linfocítica crónica. Tres de cuatro individuos presentaron inmunofenotipo de tipo leucemia linfocítica crónica, todas con bajo recuento. A su vez, en estos individuos se observa de manera significativa un mayor número de células/ µl en subpoblaciones linfocitarias T, junto con mayor predisposición a la enfermedad. Las poblaciones clonales descritas aumentan a lo largo del tiempo de manera no significativa. Conclusiones. La frecuencia y comportamiento de la linfocitosis monoclonal de célula B en pacientes con antecedentes familiares de síndromes linfoproliferativos crónicos B es similar a lo encontrado en estudios relacionados, lo que sugiere que no existe afectación de genes de mayor relevancia que puedan desencadenar una proliferación clonal descontrolada, pero que generan desregulación inmunológica que podría indicar un mayor riesgo de infección grave en estos individuos.

Introduction. Monoclonal B-cell lymphocytosis generally precedes chronic lymphocytic leukemia, affecting about 12% of the healthy adult population. This frequency increases in relatives of patients with chronic B-cell lymphoproliferative disorders. Objective. To determine the frequency of monoclonal B-cell lymphocytosis in relatives of patients with chronic B-cell lymphoproliferative disorders, their immunophenotypic/ cytogenetic characteristics, a possible relationship with infectious agents, and short-term follow-up in the Colombian population. Materials and methods. Fifty healthy adults with a family history of chronic B-cell lymphoproliferative disorders were studied using multiparametric flow cytometry, cytogenetic/serological testing, lifestyle survey, and 2-year follow-up. Results. The frequency of monoclonal B-cell lymphocytosis found was 8%, with a predominance of female gender and advanced age, increasing to 12.5% for individuals with a family history of chronic lymphocytic leukemia. Three out of four individuals presented chronic lymphocytic leukemia-type immunophenotype, all with low counts. In turn, a significantly higher number of cells/µΙ is observed in these individuals in T lymphocyte subpopulations, together with a greater predisposition to the disease. The described clonal populations increase over time in a non-significant manner. Conclusions. The frequency and behavior of monoclonal B-cell lymphocytosis in patients with family history of chronic B-cell lymphoproliferative disorders are like those found in related studies, which suggests that there is no involvement of more relevant genes that can trigger uncontrolled clonal proliferation, but that generates immunological deregulation that could justify a greater risk of serious infection in these individuals.

Prevalencia de anticuerpos contra SARS-CoV-2 en pacientes con cáncer y trabajadores de la salud vacunados con dos dosis de BNT162b2 o AZD122. Análisis de propensión / Prevalence of SARS-CoV-2 antibodies in cancer patients and healthcare workers vaccinated with two doses of BNT162b2 or AZD122. A propensity analysis

Resumen Antecedentes: La vacunación es la intervención más efectiva para reducir la carga de enfermedad por SARS-CoV-2; sin embargo, persisten brechas en el conocimiento en relación con la respuesta inmunológica de los pacientes con cáncer (PC). Objetivos: Evaluar la respuesta humoral (anticuerpos anti-S) en PC y trabajadores de salud (TS) vacunados con dos dosis de la vacuna BNT162b2 o AZD122. Material y métodos: Se cuantificaron anticuerpos poliespecíficos contra la proteína de espiga de SARS-CoV-2 (anti-S) y se efectuó una puntuación de propensión 1:1 para equilibrar las características basales. Se realizaron regresiones logísticas múltiples para evaluar el efecto de las variables relacionadas con la respuesta humoral. Resultados: Se incluyeron 127 PC (22 %) y 439 TS (78 %). Ambas poblaciones desarrollaron anticuerpos anti-S en respuesta a la vacunación. La vacuna de ARNm (BNT162b2) se asoció a mayor probabilidad de mostrar concentraciones de anticuerpos anti-S ≥ 1000 UI/mL, mientras que el cáncer activo se relacionó con menor probabilidad de presentar títulos altos de anticuerpos. Conclusiones: La vacuna BNT162b2 se asoció a respuesta humoral mayor. Es necesario contar con más información y estrategias de vacunación en pacientes inmunosuprimidos. Es relevante la selección de los mejores biológicos para esta población y considerar las características individuales.

Abstract Background: Vaccination is the most effective intervention for reducing the burden of SARS-CoV-2-related disease; however, gaps in knowledge regarding cancer patients (CPs) immune response persist. Objectives: To evaluate the humoral response (anti-S antibodies) in CPs and healthcare workers (HCWs) vaccinated with two doses of BNT162b2 or AZD122 vaccines. Material and methods: Polyspecific anti-SARS-CoV-2 spike protein (anti-S) antibodies were quantified, and a 1:1 propensity score was used to balance baseline characteristics. Multiple logistic regressions were carried out to evaluate the effect of humoral response-related variables. Results: One-hundred and twenty-seven CPs (22 %) and 439 HCWs (78 %) were included. Both populations developed anti-S antibodies in response to vaccination. The mRNA-based vaccine (BNT162b2) was associated with higher odds of having anti-S antibody titers ≥ 1,000 U/mL, while active cancer was related to a lower probability of developing high antibody titers. Conclusions: The BNT162b2 vaccine was associated with a higher humoral response. It is necessary for more information and vaccination strategies to be available for immunosuppressed patients in order to select the best biologics for this population based on individual characteristics.

Ciento cincuenta años de hebefrenia. Una revisión

Introducción: La publicación del artículo de Hecker sobre la hebefrenia en 1871 fue un hito fundamental para la psiquiatría clínica. A pesar del reconocimiento inicial, se alzaron muchas voces en contra de esta categoría diagnóstica y sus límites se fueron diluyendo a lo largo del siglo XX hasta su desaparición a comienzos de este siglo -con el resto de los subtipos de esquizofrenia- del DSM y la CIE. Discusión: Contrariamente a su disolución conceptual, la consistencia del cuadro clínico hace posible que surjan otros criterios para continuar o reiniciar su estudio sistemático. Sobresalen en este sentido los conceptos de esquizofrenia deficitaria, de hebefrenia como sustitución de la esquizofrenia en su conjunto y las hebefrenias como esquizofrenias sistemáticas de Leonhard. En el presente artículo se discuten los principales conflictos diagnósticos de la categoría de hebefrenia a lo largo del tiempo, haciendo hincapié en la problemática de las últimas décadas. Conclusiones: El concepto de hebefrenia comenzó a revalorizarse en los últimos arios y los conceptos de esquizofrenia deficitaria, de hebefrenia como categoría mayor y de hebefrenias sistemáticas permiten profundizar en nuevas investigaciones sobre este cuadro fundacional de la psiquiatría clínica.

Introduction: The publication of Hecker's article on hebephrenia in 1871 was a fundamental milestone for clinical psychiatry. Despite the initial recognition, many voices were raised against this diagnostic category and its limits were attenuated throughout the 20th century until its disappearance at the beginning of this century (along with the other subtypes of schizophrenia) in the DSM and ICD. Discussion: However, given the consistency of the clinical picture, there is the possibility of other criteria emerging that would lead its systematic study to continue or recommence. In this sense, the concepts of deficit schizophrenia, hebephrenia as a replacement for schizophrenia as a whole, and Leonhard's hebephrenias as systematic schizophrenias stand out. This article discusses the main diagnostic conflicts of the category of hebephrenia over time, with emphasis on the problems of recent decades. Conclusions: The concept of hebephrenia has begun to be revalued in recent years, and the concepts of deficit schizophrenia, of hebephrenia as a major category, and of systematic hebephrenias allow further investigation of this foundational picture of clinical psychiatry.

Síndrome de infusión de propofol y COVID-19. Reporte de caso / Propofol and COVID-19 infusion syndrome. Case report

Resumen: La forma grave de neumonía por SARS-CoV-2 (COVID-19) cursa en la mayoría de los casos con un síndrome de dificultad respiratoria aguda (SDRA). Es necesario emplear sedación durante su ventilación mecánica, el propofol es el que más de utiliza por su farmacocinética y farmacodinamia. El propofol es un anestésico que se usa ampliamente en las unidades de cuidados intensivos. Su empleo puede provocar un efecto adverso poco frecuente, pero en extremo grave, conocido como síndrome por infusión de propofol (SIP), el cual se encuentra estrechamente asociado a la velocidad de infusión aunado a factores de riesgos propios del paciente. Se caracteriza principalmente por inestabilidad hemodinámica, acidosis láctica y por progresión a disfunción multiorgánica. Se presenta un caso de SIP en paciente con síndrome de dificultad respiratoria aguda (SDRA) secundario a SARS-CoV-2 que desarrolla esta complicación asociada a la sedación. Se discute fisiopatológica clínica y consideraciones que deberán tomarse en cuenta al momento de su utilización en infusión continua.

Abstract: The severe form of SARS-CoV-2 pneumonia (COVID-19) occurs in most cases with acute respiratory distress syndrome (ARDS), requiring the use of sedation during mechanical ventilation, with propofol being the most widely used for its pharmacokinetics and pharmacodynamics. Propofol is a widely used anesthetic in intensive care units (ICU). Its use can cause an infrequent but extremely serious adverse effect, known as propofol infusion syndrome (PRIS), which is closely associated with the speed of infusion coupled with risk factors specific to the patient, the clinical features of PRIS are hemodynamic instability, lactic acidosis and with progression to multi-organ dysfunction. We present a case of SIP in a patient with acute respiratory distress syndrome (ARDS) secondary to SARS-CoV-2 who develops this complication associated with sedation, discusses clinical pathophysiology and considerations that should be taken into account when using it in continuous infusion.

Non-reperfused ST-elevation myocardial infarction: notions from a low-to-middle-income country / Infarto de miocardio con elevación del ST no reperfundido: nociones de un país de ingresos bajos a medios

Abstract Objective: The objective of the study was to analyze the differences between survivors and non-survivors with non-reperfused ST-segment elevation myocardial infarction (STEMI) and to identify the predictors of in-hospital mortality. Methods: A retrospective cohort study included non-reperfused STEMI patients from October 2005 to August 2020. Patients were classified into survivors and non-survivors. We compared patient characteristics, treatments, and outcomes among the groups and identified factors associated with in-hospital mortality. Results: We included 2442 patients with non-reperfused STEMI and we found a mortality of 12.7% versus 7.2% in reperfused STEMI. The main reason for non-reperfusion was delayed presentation (96.1%). Non-survivors were older, more often women, and had diabetes, hypertension, or atrial fibrillation. The left main coronary disease was more frequent in non-survivors as well as three-vessel disease. Non-survivors developed more in-hospital heart failure, reinfarction, atrioventricular block, bleeding, stroke, and death. The main predictors for in-hospital mortality were renal dysfunction (HR 3.41), systolic blood pressure < 100 mmHg (HR 2.26), and left ventricle ejection fraction < 40% (HR 1.97). Conclusion: Mortality and adverse outcomes occur more frequently in non-reperfused STEMI. Non-survivors tend to be older, with more comorbidities, and have more adverse in-hospital outcomes.

Resumen Objetivo: Analizar las diferencias entre los sobrevivientes y no sobrevivientes con infarto agudo de miocardio no reperfundido y conocer los predictores de mortalidad intrahospitalaria. Métodos: Estudio de cohorte retrospectiva que incluyó pacientes con infarto agudo de miocardio no reperfundido de octubre de 2005 a agosto de 2020. Se clasificaron los pacientes de acuerdo a su estado de sobrevida y se compararon las características clínicas, tratamientos y desenlaces para poder identificar los predictores de mortalidad intrahospitalaria. Resultados: Se incluyeron 2442 pacientes con infarto agudo de miocardio no reperfundido, en los que se encontró una mortalidad de 12.7% vs 7.2% los que si recibieron tratamiento de reperfusión. La principal razón para no recibir tratamiento de reperfusión fue el retraso en la atención médica (96.1%). Los no sobrevivientes tuvieron mayor edad, fueron mujeres y tuvieron mayor frecuencia de diabetes, hipertensión y fibrilación atrial. El tronco de la coronaria izquierda y la enfermedad trivascular fueron más frecuentes en los que no sobrevivieron. Los pacientes que no sobrevivieron desarrollaron más insuficiencia cardiaca, reinfarto, bloqueo atrioventricular, sangrados, evento vascular cerebral y muerte. Los principales predictores de mortalidad intrahospitalaria fueron: insuficiencia renal (HR 3.41), tensión arterial sistólica al ingreso < 100 mmHg (HR 2.26) y fracción de eyección del ventrículo izquierdo < 40% (HR 1.97). Conclusiones: Los pacientes con infarto de miocardio no reperfundido tienen mayor mortalidad y desenlaces adversos. Los no sobrevivientes fueron mayores, con más comorbilidades y desarrollaron más desenlaces adversos intrahospitalarios.

Hemodynamic responses during inspiratory muscle exercise in healthy young adults / Respuestas hemodinámicas durante el ejercicio de los músculos inspiratorios en adultos jóvenes sanos / Respostas hemodinâmicas durante exercício muscular inspiratório em jovens saudáveis

ABSTRACT The literature on hemodynamic responses during inspiratory muscle exercise (IME) lacks a consensus. To evaluate and compare hemodynamic responses during an IME session with and without resistive load, 15 sedentary men were subjected to two randomized IME sessions: one with 40% of maximal inspiratory pressure (IME 40%) and another without a resistive load (Sham), both of which were performed for two minutes over eight sessions with one-minute intervals. Systolic blood pressure (SBP), diastolic blood pressure (DBP), mean blood pressure (MBP), total peripheral resistance (TPR), stroke volume (SV), cardiac output (CO), and heart rate (HR) were measured by infrared digital photoplethysmography during five basal minutes and during the IME sessions. One-way analysis of variance and the Student's t test for paired data were used to analyze hemodynamic response and delta values between sessions. Effect size was evaluated by Cohen's D. A 5% significance level was adopted. SBP responses (sham: ∆−1±2 vs. 40%: ∆−4±2mmHg, p=0.27), DBP (sham: ∆2±1 vs. 40%: ∆1±2mmHg, p=0.60) and MBP (sham: ∆2±1 vs. 40%: ∆0±2mmHg, p=0.28) were similar between sessions. HR increases were higher in the 40% IME session than in the sham session (sham: ∆9±2 vs. 40%: ∆3±2bpm, p=0.001). SV only decreased during the sham session but responses were similar between sessions (sham: ∆−2±2 vs. IME 40%: ∆−6±2ml, p=0.13). Both sessions did not change SBP, DBP, MBP, CO, and TPR, but we observed a greater increase in HR in the IME 40% session. Only the Sham session decreased SV.

RESUMEN No hay consenso en la literatura sobre las respuestas hemodinámicas durante el ejercicio muscular inspiratorio (EMI). El objetivo de este estudio fue evaluar y comparar las respuestas hemodinámicas durante una sesión de EMI con y sin carga resistiva. Para ello, quince hombres sedentarios recibieron dos sesiones aleatorias de EMI: el 40% de la presión inspiratoria máxima (EMI 40%) y sin carga resistiva (sham), realizadas durante dos minutos, ocho sesiones y a intervalos de un minuto. La presión arterial sistólica (PAS), la presión arterial diastólica (PAD), la presión arterial media (PAM), la resistencia periférica total (RPT), el volumen sistólico (VS), el gasto cardíaco (GC) y la frecuencia cardíaca (FC) se midieron mediante fotopletismografía infrarroja digital durante cinco minutos al inicio y durante las sesiones de EMI. Se utilizaron ANOVA unidireccional y la prueba t de Student a datos emparejados para analizar la respuesta hemodinámica y los valores delta entre las sesiones. El tamaño del efecto se evaluó por el d de Cohen. El nivel de significancia adoptado fue de 5%. Las respuestas de PAS (sham: Δ−1±2 vs. 40%: ∆−4±2mmHg, p=0,27), PAD (sham: ∆2±1 vs. 40%: ∆1±2mmHg, p=0,60) y PAM (sham: ∆2±1 vs. 40%: ∆0±2mmHg, p=0,28) fueron similares entre las sesiones. El incremento de la FC fue mayor en la sesión de EMI 40% comparada con la sesión sham (sham: Δ9±2 vs. 40%: ∆3±2bpm, p=0,001). El VS tuvo una disminución exclusiva durante la sesión sham, pero la respuesta fue similar entre las sesiones (sham: Δ−2±2 vs. EMI 40%: ∆−6±2ml, p=0,13). Ambas sesiones no tuvieron cambios en las variables PAS, PAD, PAM, DC y RPT, pero se observó un mayor incremento de la FC en la sesión EMI 40%. Solamente en la sesión sham hubo una reducción del VS.

RESUMO A literatura carece de um consenso sobre respostas hemodinâmicas durante o exercício muscular inspiratório (EMI). Este estudo buscou avaliar e comparar as respostas hemodinâmicas durante uma sessão de EMI com e sem carga resistiva. Para tanto, 15 homens sedentários foram submetidos a duas sessões randomizadas de EMI: 40% da pressão inspiratória máxima (EMI 40%) e sem carga resistiva (sham), realizadas por dois minutos em oito sessões e com intervalos de um minuto. A pressão arterial sistólica (PAS), pressão arterial diastólica (PAD), pressão arterial média (PAM), resistência periférica total (RPT), volume sistólico (VS), débito cardíaco (DC) e frequência cardíaca (FC) foram medidos por fotopletismografia infravermelha digital por cinco minutos basais e durante as sessões de EMI. Anova de uma via e o teste t de Student para dados pareados foram usados para analisar a resposta hemodinâmica e os valores delta entre as sessões. O tamanho do efeito foi avaliado pelo d de Cohen. Adotou-se nível de significância de 5%. As respostas de PAS (sham: ∆−1±2 vs. 40%: ∆−4±2mmHg, p=0,27), PAD (sham: ∆2±1 vs. 40%: ∆1±2mmHg, p=0,60) e PAM (sham: ∆2±1 vs. 40%: ∆0±2mmHg, p=0,28) foram semelhantes entre as sessões. Os aumentos da FC foram maiores na sessão de EMI 40% do que nas sessões sham (sham: ∆9±2 vs. 40%: ∆3±2bpm, p=0,001). O VS diminuiu exclusivamente durante a sessão sham mas a resposta foi semelhante entre as sessões (sham: ∆−2±2 vs. EMI 40%: ∆−6±2ml, p=0,13). Ambas as sessões não causaram alteração nas variáveis PAS, PAD, PAM, DC e RPT, mas notamos um aumento maior da FC na sessão EMI 40%. Apenas a sessão sham reduziu o VS.

Las variables sociales y la conciencia meta-cognitiva de los jóvenes adultos colombianos / Social variables and metacognitive awareness of Colombian young adults / Variáveis sociais e consciência metacognitiva de jovens adultos colombianos

Resumen (analítico) La metacognición se define como un proceso reflexivo que permite a las personas monitorear, controlar y autorregular su comportamiento. Sin embargo, la metacognición rara vez se ha estudiado con variables más allá del contexto educativo, como variables sociales, conductuales o clínicas. Así, el propósito del presente estudio fue explorar la relación entre las variables sociales y la conciencia metacognitiva subjetiva y si estas mismas variables sociales predicen componentes de la conciencia metacognitiva (conocimiento y regulación de la cognición). Con una muestra de estudiantes universitarios (N = 246), los resultados revelaron que no solo existen correlaciones significativas entre algunas variables sociales y ambos componentes de la conciencia metacognitiva, sino que esas mismas variables sociales predijeron la conciencia metacognitiva. Se discuten las implicaciones de estos resultados en contextos educativos y clínicos.

Abstract (analytical) Metacognition is defined as a higher-order reflective process that allows individuals to monitor, control, and self-regulate their behavior. However, metacognition has rarely been studied with variables beyond the educational context such as social, behavioral and clinical variables. The purpose of this study was to explore the relationship between social variables and subjective metacognitive aware-ness and whether these same social variables can predict components of metacognitive awareness (knowledge and regulation of cognition). Working with a sample of university students (N = 246), the results of this study identified that there were not only significant correlations between some social variables and both components of metacognitive awareness, but that those same social variables could predict metacognitive awareness. Implications for these outcomes in educational and clinical contexts are discussed.

Resumo (analítico) A metacognição é definida como um processo reflexivo de ordem superior que permite às pessoas monitorar, controlar e autorregular seu comportamento. No entanto, a metacognição raramente foi estudada com variáveis fora do contexto educacional, como variáveis sociais, comportamentais ou clínicas. Assim, o objetivo do presente estudo foi explorar a relação entre as variáveis sociais e a consciência metacognitiva subjetiva e se essas mesmas variáveis sociais predizem os componentes da consciência metacognitiva (conhecimento e regulação da cognição). Com uma amostra de estudantes universitários (N = 246), os resultados revelaram que não apenas existem correlações significativas entre algumas variáveis sociais e ambos os componentes da consciência metacognitiva, mas que essas mesmas variáveis sociais predizem a consciência metacognitiva. As implicações desses resultados em contextos educacionais e clínicos são discutidas.

Resistência muscular periférica e inspiratória reduzida em pacientes com cirrose hepática: um estudo transversal / Reduced peripheral and inspiratory muscle endurance in patients with liver cirrhosis: a cross-sectional study

ABSTRACT BACKGROUND: Liver cirrhosis (LC) causes several musculoskeletal changes. OBJECTIVE: To test the hypothesis that the peripheral and inspiratory muscle endurance are reduced in patients with liver cirrhosis. METHODS: Twenty-one patients with LC (LC group; 61±14 years) and 18 age-matched subjects (control group; 56±17 years) had accepted to participate in this cross-sectional observational study. To assess peripheral muscle endurance, all volunteers performed a rhythmic handgrip exercise at 45% of their maximum voluntary contraction. A metronome was used to control the contraction-relaxation cycles at 60/min. The inspiratory muscle endurance was assessed using PowerBreath®. Participants underwent inspiratory muscle exercise at 60% of their maximal inspiratory muscle strength. The time until failure characterized the muscle endurance for both handgrip and inspiratory muscle exercises. Additionally, the quality of life of the participants was assessed. RESULTS: The muscle endurance was lower in the LC group when compared to the control group for both handgrip (67 vs 130 s, P<0.001) and inspiratory muscle exercises (40 vs 114 s, P<0.001). The peripheral muscle endurance was directly correlated with the total quality of life score (r=0.439, P=0.01) and to the following domains: fatigue (r=0.378 e P=0.030), activity (r=0.583, P=0.001), systemic symptoms (r=0.316, P=0.073) and preoccupation (r=0.370, P=0.034). The inspiratory muscle endurance was inversely correlated with the total quality of life score (r=0.573, P=0.001) and the following domains: fatigue (r=0.503, P=0.002), activity (r=0.464, P=0.004), systemic symptoms (r=0.472, P=0.004), abdominal symptoms (r=0.461, P=0.005), emotional function (r=0.387, P=0.02) and preoccupation (r=0.519, P=0.001). CONCLUSION: Both peripheral and inspiratory muscle endurance were lower in LC patients when compared to the control group.

RESUMO CONTEXTO: A cirrose hepática (CH) causa várias alterações musculoesqueléticas. OBJETIVO: Testar a hipótese de que as resistências dos músculos periféricos e inspiratórios estão reduzidas em pacientes com CH. MÉTODOS: Vinte e um pacientes com CH (grupo CH; 61±14 anos) e 18 indivíduos pareados por idade (grupo controle; 56±17 anos) aceitaram participar deste estudo observacional transversal. Para avaliar a resistência muscular periférica, todos os voluntários realizaram um exercício de preensão manual rítmica a 45% de sua contração voluntária máxima. Um metrônomo foi usado para controlar os ciclos de contração-relaxamento a 60/min. A resistência muscular inspiratória foi avaliada com o PowerBreath®. Os participantes foram submetidos a exercícios musculares inspiratórios a 60% de sua força muscular inspiratória máxima. O tempo até a falha caracterizou a resistência muscular para os exercícios de preensão manual e de músculos inspiratórios. Além disso, foi avaliada a qualidade de vida dos participantes. RESULTADOS: A resistência muscular foi menor no grupo CH quando comparada ao grupo controle tanto para os exercícios de preensão manual (67 vs 130 s, P<0,001) quanto para os músculos inspiratórios (40 vs 114 s, P<0,001). A resistência muscular periférica foi diretamente correlacionada com o escore total de qualidade de vida (r=0,439, P=0,01) e com os seguintes domínios: fadiga (r=0,030, P=0,378), atividade (r=0,378 e P=0,030), sintomas sistêmicos (r=0,316, P=0,073) e preocupação (r=0,370, P=0,034). A resistência muscular inspiratória foi inversamente correlacionada com o escore total de qualidade de vida (r=0,573, P=0,001) e com os seguintes domínios: fadiga (r=0,503, P=0,002), atividade (r=0,464, P=0,004), sintomas sistêmicos (r=0,472, P=0,004), sintomas abdominais (r=0,461, P=0,005), função emocional (r=0,387, P=0,02) e preocupação (r=0,519, P=0,001). CONCLUSÃO: As resistências musculares periférica e inspiratória foram menores nos pacientes com CH quando comparados ao grupo controle.

DSM-5 Pathological Personality Traits Among College Students / Rasgos de Personalidad Patológica según el DSM-5 en una muestra de estudiantes universitarios

Abstract Individuals with personality pathology exhibit significant impairment in intrapersonal and interpersonal functioning that compromise psychological welfare of significant others. However, common pathological personality traits in college students remain unclear. This study aimed to describe pathological personality traits identified in the Diagnostic and Statistical Manual of Mental Disorders (5th ed., DSM-5) Section III alternative model of personality disorder in college students. This is a quantitative, non-experimental, cross-sectional study. Participants were 81 college students from a Colombian University who were administered the Personality Inventory for DSM-5. Findings suggest that women scored significantly higher than men on hostility (z=-2.577; p=0.01; n 2 = 0.082). A medium size effect was found (p> 0.039) through the ( 2 index. The remaining variables did not prove statistically significant differences when controlling the participant gender (p < 0.05). The personality domain that reached the most dysfunctionality was disinhibition (risk taking, impulsivity, rigid perfectionism). Negative affect had the highest mean score and gender differences in facets and domains showed that women scored significantly higher than men on hostility. However, more studies into the pathological personality traits established by the PID-5 is required if the shift to a dimensional model is likely to occur in future editions of the DSM.

Resumen Las personas con patologías de la personalidad exhiben un deterioro significativo en el funcionamiento inter-intrapersonal que compromete el bienestar psicológico de los más cercanos. Sin embargo, los rasgos de personalidad patológica más comunes en estudiantes universitarios aún no son muy claros. Este estudio busca describir los rasgos de personalidad patológica identificados en el manual diagnóstico y estadístico de trastornos mentales (DSM-5), en estudiantes universitarios. Este es un estudio cuantitativo, transversal, no experimental. Los participantes fueron 81 estudiantes del programa de psicología de una Universidad Colombiana quienes fueron evaluados por medio del Inventario de personalidad para el DSM-5. Los hallazgos sugieren que las mujeres tuvieron puntuaciones significativamente más altas que los hombres en hostilidad (z=-2.577; p=0.01; n 2 = 0.082). Se encontró un tamaño del efecto medio (p> 0.039) por medio del índice ( 2 . En las demás variables no se encontraron diferencias estadísticamente significativas en cuanto al género (p < 0.05). Inhibición presentó el grado más alto de disfuncionalidad. Afecto negativo obtuvo la puntuación promedio más alta y las diferencias de género muestran que las mujeres tienden a ser más hostiles que los hombres. Sin embargo, son necesarios más estudios sobre los rasgos de personalidad patológica propuestos por el Inventario de personalidad para el DSM-5 si a futuro se propone un modelo dimensional.

Hemodynamics and cardiac autonomic modulation after an acute concurrent exercise circuit in older individuals with pre- to established hypertension

OBJECTIVES: Few studies have investigated whether post-exercise hypotension (PEH) after concurrent exercise (CEX) is related to changes in cardiac output (Q) and systemic vascular resistance (SVR) in older individuals. We tested whether PEH after a single bout of CEX circuits performed in open-access facilities at the Third Age Academies (TAA) in Rio de Janeiro City (Brazil) would be concomitant with decreased Q and SVR in individuals aged ≥60 years with prehypertension. Moreover, we assessed autonomic modulation as a potential mechanism underlying PEH. METHODS: Fourteen individuals (age, 65.8±0.9 y; systolic/diastolic blood pressure [SBP/DBP], 132.4±12.1/72.8±10.8 mmHg; with half of the patients taking antihypertensive medications) had their blood pressure (BP), heart rate (HR), Q, SVR, HR variability (HRV), and spontaneous baroreflex sensitivity (BRS) recorded before and 50 min after CEX (40-min circuit, including seven stations of alternate aerobic/resistance exercises at 60-70% HR reserve) and non-exercise control (CONT) sessions. The study protocol was registered in a World Health Organization-accredited office (Trial registration RBR-7BWVPJ). RESULTS: SBP (Δ=−14.2±13.1 mmHg, p=0.0001), DBP (Δ=−5.2±8.2 mmHg, p= 0.04), Q (Δ=−2.2±1.5 L/min, p=0.0001), and BRS (Δ=−3.5±2.6 ms/mmHg; p=0.05) decreased after CEX as compared with the CONT session. By contrast, the HR increased (Δ=9.4±7.2 bpm, p<0.0001), and SVR remained stable throughout the postexercise period as compared with the CONT session (Δ=0.10±0.22 AU, p=0.14). We found no significant difference between the CEX and CONT with respect to the HRV indexes reflecting autonomic modulation. CONCLUSION: CEX induced PEH in the older individuals with prehypertension status. At least in the first 50 min, PEH occurred parallel to the decreased Q and increased HR, while SVR was not different. The changes in autonomic outflow appeared to be unrelated to the acute cardiac and hemodynamic responses.

Telemedicina: experiencia de monitoreo telefónico en Nutrición Enteral Domiciliaria en tiempos de Pandemia por COVID-19 / Telemedicine: phone monitoring experience upon Home Enteral Nutrition during COVID-19 Pandemic

Resumen Introducción: la aplicación de la telemedicina permite asegurar la atención sanitaria en el contexto de la pandemia por COVID-19. Objetivo: evaluar la telemedicina para el monitoreo de pacientes con nutrición enteral domiciliaria. Materiales y Método: estudio transversal, observacional y descriptivo, con muestreo no probabilístico intencional entre enero y junio de 2020. Se incluyeron pacientes con dificultad para acceder al cuidado domiciliario de profesionales en forma presencial. Todos los pacientes tenían seguro médico, sistema de emergencias a domicilio y un centro asistencial de referencia para derivación. Fueron excluidos pacientes que obligatoriamente necesitaban seguimiento presencial, imposibilidad de comunicación con familiar a cargo y negativa del paciente/familia a la modalidad remota. Variables: edad, sexo, diagnóstico médico, valoración global subjetiva (VGS) en las distintas comunicaciones con el paciente, adherencia a la indicación nutricional, satisfacción del paciente y complicaciones. Se realizó una encuesta telefónica de satisfacción. Las complicaciones se clasificaron en relacionadas y no relacionadas con el soporte nutricional enteral domiciliario (SNED). Resultados: se incluyeron 18 pacientes con diversos diagnósticos médicos. Se realizaron 80 comunicaciones con un total de 2370 días de seguimiento (131,7 ± 63,7 días/paciente), VGS inicial (n=18): 27,7% (n=5) estaba bien nutrido, 61,1% (n=11) en riesgo de desnutrición y 11,1% (n=2) presentaba desnutrición severa. En las 80 comunicaciones, el 97,5% (n=78) cumplió al 100% la prescripción nutricional y el 2,5% (n=2) la respetó en un 50%. Al finalizar el estudio, todos lograron cumplirla. Se observaron 15 eventos adversos: 13 relacionados con el SNED y 2 no relacionados. Dos pacientes fallecieron durante el seguimiento a causa de su patología de base. Satisfacción: el 72,2% (n=13) definió la atención general como muy buena, y el 27,7% (n=5) como excelente. En relación a la atención profesional se encontró que el 22,2% (n=4) la categorizó como excelente, 66,6% (n=12) muy buena y el 11,1% (n=2) buena. Conclusiones: la telemedicina es útil para monitorear el SNED permitiendo disminuir la inequidad geográfica y mejorar la accesibilidad a los cuidados de salud.

Abstract Introduction. telemedicine guarantees health care in the context of the COVID-19 pandemic. Objective: to evaluate telemedicine for monitoring patients with home enteral nutrition. Materials and methods: an observational, descriptive and cross-sectional study, with intentional non-probability sampling, was conducted between January and June, 2020. The patients included were the ones with difficulty to have access to home care by professionals face-to-face. All the patients had health insurance, a home emergency service and a referral center. Patients who necessarily needed face-to-face follow-up, impossibility of communication with a family member in charge, and refusal of the patient / family to the remote modality were excluded. Variables: age, gender, diagnosis, subjective global assessment (SGA) in the different communications with the patient, adherence to nutritional indication, patient satisfaction and complications. A telephone satisfaction survey was conducted. Complications were classified as related and unrelated to home enteral nutritional support (SNED). Results: 18 patients with various medical diagnoses were included. 80 communications were made with a total of 2370 days of follow-up (131.7 ± 63.7 days / patient). SGA (n = 80): 33.75% (n = 27) were well nourished, 58.75% (n = 47) at risk of malnutrition, and 7.5% (n = 6) had severe malnutrition. 97.5% (n = 78) complied 100% with the nutritional prescription and 2.5% (n = 2) respected it by 50%. At the end of the study, all were able to fulfil it. 15 adverse events were observed: 8 related to SNED and 7 unrelated. Two patients died during follow-up due to their underlying pathology. Satisfaction: 72.22% (n = 13) defined general care as very good, and 27.78% (n = 5) as excellent. In relation to professional care, it was found that 22.22% (n = 4) categorized it as excellent, 66.67% (n = 12) very good and 11.11% (n = 2) good. Conclusion: Telemedicine is useful to monitor the SNED, allowing to reduce geographic inequity and improve accessibility to health care.

A left diaphragmatic hernia with a hernia sac containing the spleen, colon, tail of pancreas and left adrenal gland. The patient underwent surgical repair via a left subcostal incision; the hernia sac was reduced, the diaphragmatic defect was repaired with a mesh and the Ladd procedure was performed due to the diagnosis of intestinal malrotation.

Obesity: Perceived Self-Efficacy, Emotional Regulation and Stress / Obesidade: Autoeficácia Percebida, Regulação Emocional e Estresse / Obesidad: Autoeficacia Percibida, Regulación Emocional y Estrés

Abstract Obesity increases the risk of non-transmissible chronic illnesses decreasing the quality of life and life expectancy. This investigation aims to define a psychological profile for the treatment of the target population evaluating the levels of self-efficacy perceived, difficulty in emotional regulation and stress. Eighty-six adults participated, including 63 women and 23 men who pertained to OBEMOB in Temuco. The results indicate that the level of stress, trust in problem solving skills, as well as ability to solve problems and unexpected situations differs according to the type of obesity (p<0.05). In addition, there is a negative relation between general self-efficacy and difficulty of emotional regulation (rho=-0.419) while stress and BMI demonstrate a positive relation (rho=0,380).

Pancitopenia inducida por bajas dosis de metotrexato / Low dose methotrexate induced pancytopenia

Resumen El metotrexato es un agente que antagoniza el metabolismo del ácido fólico reduciendo los niveles de tetrahidrofolato en las células, inhibiendo su replicación y la síntesis de proteínas. Actualmente, se emplea en el tratamiento de diversas enfermedades malignas o inflamatorias. Tiene descritos numerosos efectos tóxicos, tanto a dosis altas en esquemas quimioterapéuticos como bajas de larga duración para inmunosupresión, los cuales incluyen compromiso hepático, neurológico, cutáneo, gastrointestinal y, con menor frecuencia, afección pulmonar y hematológica. Se reporta el caso de un paciente de edad avanzada quien se encontraba en tratamiento con metotrexato por más de cuatro años y acudió al servicio de urgencias con toxicidad severa resaltándose pancitopenia y concomitantemente choque séptico, quien, a pesar del manejo establecido, presentó evolución clínica desfavorable. Se resalta la importancia de tener en cuenta esta toxicidad dado su subregistro en Colombia y la repercusión que puede tener en un paciente incluso al establecer el manejo adecuado.

Abstract Methotrexate is an agent that antagonizes the metabolism of folic acid by reducing the levels of tetrahydrofolate in cells, which inhibits cellular replication and protein synthesis. It is currently used in the treatment of various malignancies and some inflammatory diseases such as rheumatoid arthritis. It has described numerous toxic effects both at high doses in chemotherapeutic schemes and long-term low doses for immunosuppression; these include renal, hepatic, neurological, cutaneous, gastrointestinal, and much less frequently pulmonary and hematological involvement. This article reports the case of an elderly patient who was in treatment with methotrexate for more than four years and went to the emergency department with severe toxicity highlighting pancytopenia and concomitant septic shock, whom despite the established management presented a poor response. The importance of taking into account this toxicity is highlighted given the underreporting in Colombia and the impact it can have on a patient even when establishing the appropriate management.

Plan de análisis: La validez de apariencia fue evaluada mediante juicio de expertos; la de contenido utilizando análisis factorial; la de criterio concurrente a través del coeficiente de correlación de Pearson; la consistencia interna con el coeficiente alfa de Cronbach; la consistencia relacionada con el tiempo de aplicación y entre evaluadores, mediante la proporción de aciertos, la prueba t para comparación de medias y el coeficiente de correlación. La normalidad de los datos se determinó empleando la prueba de Shapiro Wilk. La comparación entre puntuaciones medias de hombres y mujeres se realizó utilizando la U de Mann - Whitney o t de Student. Se obtuvieron baremos para las pruebas incluidas en la investigación. Resultados: Se encontró adecuada validez de contenido para las tareas atencionales contempladas en el estudio, así mismo, adecuada validez de criterio y confiabilidad para la prueba PASAT, y baja validez de criterio y niveles moderados de confiabilidad pretest - postest, para el caso de las tareas de TMT A, B, en la muestra de estudiantes universitarios considerada en el estudio.

Abstract Objective: This study aimed to describe the results of a standardization study of some classical neuropsychological tasks for attention assessment: Trail Making Test A, B, Paced auditory serial addition test (PASAT). Methodology: The sample consisted of 208 healthy college students from Manizales, with no associated neurological or psychiatric pathology. The instruments used were the Rey verbal auditory learning test, the Rey complex test, the serial auditory test Pattern and Benton visual retention test. Analysis Plan: the validity of appearance was assessed through expert judgment; the content was evaluated by factorial analysis; the validity of concurrent criterion, through the Pearson´s correlation coefficient and the internal consistency by Cronbach's alpha coefficient. Consistency related to the time of instrument administration by different evaluators, was analyzed according to the number of hits, the difference of means and the correlation coefficient. The data consistency was analyzed by means of the Shapiro Wilk test. The male and female were collated by the U of Mann-Whitney or Student's t, and finally the scores obtained by for each one of the tests were included in the research. Results: It was evidenced adequate content validity for the attentional tasks included in the study, as well as suitable criterion validity and reliability for the PASAT test, and low criterion validity and moderate levels of pretest, posttest reliability in the case of TMT (A) and TMT (B) tasks provided by the university students sample considered in the study.

Exercise Training Improves Heart Rate Recovery after Exercise in Hypertension

Abstract Aim: This study tested the hypothesis that: 1- the exercise training would improve the heart rate recovery (HRR) decline after maximal exercise test in hypertensive patients and; 2- the exercise training would normalize HRR decline when compared to normotensive individuals. Methods: Sixteen hypertensive patients were consecutively allocated into two groups: Exercise-trained (n = 9, 47±2 years) and untrained (n = 7, 42±3 years). An exercise-trained normotensive group (n = 11, 41±2 years) was also studied. Heart rate was evaluated by electrocardiogram. The autonomic function was evaluated based on heart rate changes on the first and the second min of recovery after the maximal exercise test. Exercise training consisted of three 60-minute exercise sessions/week for 4 months. Results: In hypertensive patients, exercise training significantly increased the HRR decline in the first (-19±2 vs. -34±3 bpm, P = 0.001) and second (-33±3 vs. -49±2 bpm, P = 0.006) minutes after the maximal exercise test. In addition, after exercise training, the initial differences in the HRR decline after exercise between hypertensive patients and normotensive individuals were no longer observed (first minute: -34±3 vs. -29±3 bpm, P = 0.52, and second minute: -49±2 vs. -47±4 bpm, P = 0.99). Conclusion: Hypertension causes a delay in HRR after the maximal exercise test yet the exercise training normalizes HRR during the post-exercise period in hypertensive patients.
