Collective effects of rising average temperatures and heat events on oviparous embryos.

Survival of the immobile embryo in response to rising temperature is important to determine a species' vulnerability to climate change. However, the collective effects of 2 key thermal characteristics associated with climate change (i.e., rising average temperature and acute heat events) on embryonic survival remain largely unexplored. We used empirical measurements and niche modeling to investigate how chronic and acute heat stress independently and collectively influence the embryonic survival of lizards across latitudes. We collected and bred lizards from 5 latitudes and incubated their eggs across a range of temperatures to quantify population-specific responses to chronic and acute heat stress. Using an embryonic development model parameterized with measured embryonic heat tolerances, we further identified a collective impact of embryonic chronic and acute heat tolerances on embryonic survival. We also incorporated embryonic chronic and acute heat tolerance in hybrid species distribution models to determine species' range shifts under climate change. Embryos' tolerance of chronic heat (T-chronic) remained consistent across latitudes, whereas their tolerance of acute heat (T-acute) was higher at high latitudes than at low latitudes. Tolerance of acute heat exerted a more pronounced influence than tolerance of chronic heat. In species distribution models, climate change led to the most significant habitat loss for each population and species in its low-latitude distribution. Consequently, habitat for populations across all latitudes will shift toward high latitudes. Our study also highlights the importance of considering embryonic survival under chronic and acute heat stresses to predict species' vulnerability to climate change.

Efectos colectivos del aumento de las temperaturas promedio y los eventos de calor en embriones ovíparos Resumen La supervivencia de los embriones inmóviles en respuesta al incremento de temperatura es importante para determinar la vulnerabilidad de las especies al cambio climático. Sin embargo, los efectos colectivos de dos características térmicas claves asociadas con el cambio climático (i. e., aumento de temperatura promedio y eventos de calor agudo) sobre la supervivencia embrionaria permanecen en gran parte inexplorados. Utilizamos mediciones empíricas y modelos de nicho para investigar cómo el estrés térmico crónico y agudo influye de forma independiente y colectiva en la supervivencia embrionaria de los lagartos en todas las latitudes. Recolectamos y criamos lagartos de cinco latitudes e incubamos sus huevos en un rango de temperaturas para cuantificar las respuestas específicas de la población al estrés por calor crónico y agudo. Posteriormente, mediante un modelo de desarrollo embrionario parametrizado con mediciones de tolerancia embrionaria al calor, identificamos un impacto colectivo de las tolerancias embrionarias al calor agudo y crónico en la supervivencia embrionaria. También incorporamos la tolerancia embrionaria crónica y aguda al calor en modelos de distribución de especies híbridas para determinar los cambios de distribución de las especies bajo el cambio climático. La tolerancia embrionaria al calor crónico (T­crónico) permaneció constante, mientras que la tolerancia al calor agudo (T­agudo) fue mayor en latitudes altas que en latitudes bajas. La tolerancia al calor agudo ejerció una influencia más pronunciada que la tolerancia al calor crónico. En los modelos de distribución de especies, el cambio climático provocó la pérdida de hábitat más significativa para cada población y especie en su distribución de latitudes bajas. En consecuencia, el hábitat para poblaciones en todas las latitudes se desplazará a latitudes altas. Nuestro estudio también resalta la importancia de considerar la supervivencia embrionaria bajo estrés térmico crónico y agudo para predecir la vulnerabilidad de las especies al cambio climático.

The influence of social identity on attitudes toward wildlife.

Wildlife conservation depends on supportive social as well as biophysical conditions. Social identities such as hunter and nonhunter are often associated with different attitudes toward wildlife. However, it is unknown whether dynamics within and among these identity groups explain how attitudes form and why they differ. To investigate how social identities help shape wildlife-related attitudes and the implications for wildlife policy and conservation, we built a structural equation model with survey data from Montana (USA) residents (n = 1758) that tested how social identities affect the relationship between experiences with grizzly bears (Ursus arctos horribilis) and attitudes toward the species. Model results (r2  = 0.51) demonstrated that the hunter identity magnified the negative effect of vicarious property damage on attitudes toward grizzly bears (ß = -0.381, 95% confidence interval [CI]: -0.584 to -0.178, p < 0.001), which in turn strongly influenced acceptance (ß = -0.571, 95% CI: -0.611 to -0.531, p < 0.001). Our findings suggested that hunters' attitudes toward grizzly bears likely become more negative primarily because of in-group social interactions about negative experiences, and similar group dynamics may lead nonhunters to disregard the negative experiences that out-group members have with grizzly bears. Given the profound influence of social identity on human cognitions and behaviors in myriad contexts, the patterns we observed are likely important in a variety of wildlife conservation situations. To foster positive conservation outcomes and minimize polarization, management strategies should account for these identity-driven perceptions while prioritizing conflict prevention and promoting positive wildlife narratives within and among identity groups. This study illustrates the utility of social identity theory for explaining and influencing human-wildlife interactions.

La influencia de la identidad social sobre la actitud hacia la fauna Resumen La conservación de la fauna depende de condiciones de apoyo tanto sociales como biofísicas. La identidad social, como ser cazador o no, con frecuencia está asociada a las diferentes actitudes hacia la fauna. Sin embargo, no sabemos si las dinámicas dentro y entre estos grupos de identidad explican cómo las actitudes se forman y porqué son diferentes. Construimos un modelo de ecuación estructural con información de encuestas realizadas a 1,758 residentes de Montana (Estados Unidos) para conocer cómo la identidad social ayuda a formar la actitud relacionada con la fauna y las implicaciones que tiene para la conservación y políticas de fauna. El modelo analizó cómo la identidad social afecta la relación entre las experiencias con osos pardos (Ursus arctos horribilis) y la actitud hacia la especie. Los resultados del modelo (r2 = 0.51) demostraron que la identidad de cazador aumentaba el efecto negativo del daño indirecto a la propiedad sobre la actitud hacia los osos (ß=-0.381, 95% CI -0.584 a -0.178, p<0.001), lo cual en cambio tenía una gran influencia sobre la aceptación (ß=-0.571, 95% CI -0.611 a -0.531, p<0.001). Nuestros descubrimientos sugieren que la actitud de los cazadores hacia los osos probablemente se vuelve más negativa principalmente debido a las interacciones sociales del endogrupo en torno a las experiencias negativas; las dinámicas similares pueden llevar a los no cazadores a menospreciar las experiencias negativas que los miembros del exogrupo han tenido con los osos. Dada la influencia profunda que tiene la identidad social sobre la cognición humana y el comportamiento en una miríada de contextos, los patrones que observamos probablemente sean importantes en una variedad de situaciones de conservación de fauna. Para promover los resultados positivos de conservación y minimizar la polarización, las estrategias de manejo deberían considerar estas percepciones influenciadas por la identidad mientras se prioriza la prevención de conflictos y se promueven narrativas positivas de fauna dentro y entre los grupos de identidad. Este estudio demuestra la utilidad que tiene la teoría de identidad social para explicar e influenciar las interacciones humano-fauna.

Gestational diabetes mellitus early prediction by maternal body fat index: A cohort study.

OBJECTIVES: To compare the performance of maternal body fat index (BFI) assessed during the first 20+6 weeks among 138 pregnant women in an ultrasound outpatient clinic as a predictor of gestational diabetes mellitus (GDM) later in pregnancy. METHOD: Maternal visceral and subcutaneous fat was measured with a convex ultrasound probe placed in two locations on the maternal abdominal surface: the first in the mid-sagittal epigastric region, visualising epigastric fat, and the second 2cm above the maternal umbilical scar, visualising periumbilical fat. Ultrasound callipers measured the distance from dermal edge to the linea alba and after from the linea alba to the anterior hepatic surface (epigastric fat). Periumbilical fat was measured from the dermal edge to the linea alba and after from the linea alba to the anterior aortic surface. The BFI formula was [visceral adipose tissue (mm)×subcutaneous adipose tissue (mm)]/maternal height (cm). RESULTS: The best thresholds for predicting GDM outcome for epigastric and periumbilical BFI were 1.2 and 4.8, respectively. Odds ratio, sensitivity and specificity were 5.88 (95% CI 1.86-18.6), 80.9%, 58.0% for the epigastric site and 6.31 (95% CI 1.73-22.94), 84.2%, 54.2% for the periumbilical site. Pre-pregnancy body mass index compatible with adult obesity shows inadequate predictive performance for GDM outcome. Only epigastric BFI above 1.2 maintained statistical significance for GDM in the logistic regression analysis, when compared to periumbilical BFI above 4.8. CONCLUSION: Epigastric BFI above 1.2 during the first half of pregnancy may help identify women at risk of developing GDM later in pregnancy.

Murciélagos como vectores de enfermedades virales e impacto en la salud humana

Introducción: Los murciélagos se destacan por ser los únicos mamíferos voladores, con alrededor de 1 400 especies que cumplen un rol fundamental como controladores de plagas y polinizadores de plantas nocturnas. Sin embargo, su influencia sobre la salud humana se ha evidenciado cada vez más, en particular después del surgimiento de brotes epidémicos de enfermedades virales asociadas a estos mamíferos. Objetivo: Analizar la influencia de los murciélagos en la salud humana, centrándose en su papel como portadores de enfermedades virales y su potencial como reservorios y vectores de enfermedades. Métodos: Se realizó una revisión bibliográfica de la literatura utilizando descriptores MeSH y términos como: Animals, Wild Chiroptera, Virus Diseases, Zoonoses, Disease Vectors, Disease Reservoirs, Public Health, bats, Communicable Disease Control, Disease Outbreaks, Prevention and Control. Se revisaron 1 442 artículos en bases de datos y documentos oficiales, se seleccionaron las fuentes relevantes con Mendeley Desktop 1.19.4. y se obtuvieron al final 47 artículos. Resultados: Existen varias especies de murciélagos que pueden afectar la salud del ser humano y que albergan en especial virus de las familias Filoviridae, Coronaviridae y Paramixoviridae. Los murciélagos se consideran incubadoras óptimas para la propagación de virus debido a su sistema inmune único que lo hace resistente a estos agentes infecciosos. Conclusiones: La vigilancia y monitoreo de los murciélagos, junto con acciones de educación pública y una gestión adecuada de sus hábitats, son fundamentales para la detección temprana y prevención de la transmisión de nuevos virus de estos mamíferos a los humanos.

Introduction: Bats are the only flight mammals, with around 1,400 species playing critical roles as pest controllers and nocturnal plant pollinators. However, its impact on human health has become increasingly evident, especially after the appearance of epidemic outbreaks of viral diseases related to these mammals. Objetive: To analyze the influence of bats on human health, focusing on their role as carriers of viral diseases and their potential as reservoirs and vectors of diseases. Methods: A literature bibliographical review was conducted using MeSH descriptors and keywords such as: Animals, Wild Chiroptera, Virus Diseases, Zoonosis, Disease Vectors, Disease Reservoirs, Public Health, bats, Communicable Disease Control, Disease Outbreaks, Prevention and Control. 1442 articles in databases and official documents were reviewed, selecting the relevant sources with Mendeley Desktop 1.19.4., obtaining 47 articles at the end. Results: There are several species of bats that can affect human health and that mainly harbor viruses from the Filoviridae families, Coronaviridae and Paramyxoviridae. Bats are considered optimal incubators for the spread of the virus due to their unique immune system that makes them particularly resistant to these infectious agents. Conclusions: Surveillance and monitoring of bats, together with public education actions and proper management of their habitats, are essential for early detection and prevention of transmission of new viruses from these mammals to humans.

Avaliação da concordância entre os resultados da genotipagem do polimorfismo C/T-13910 e do teste de tolerância à lactose: um estudo retrospectivo populacional no Brasil / Evaluation of agreement between c/t-13910 polymorphism genotyping results and lactose tolerance test results: a retrospective population-based study in brazil

ABSTRACT Background: Lactose tolerant test (LTT) is the most broadly used diagnostic test for lactose intolerance in Brazil, is an indirect, minimally invasive and a low-cost test that is widely available in primary care and useful in clinical practice. The C/T-13910 polymorphism in lactase persistence has been well characterized in Caucasian populations, but there are no studies evaluating the concordance between C/T-13910 polymorphism genotyping results and LTT results in Brazil, where the population is highly mixed. Objective: We aimed to evaluate agreement between presence of C/T-13910 polymorphism genotyping and malabsorption in LTT results. Methods: This is a retrospective analysis of a Brazilian population whose data were collected from a single laboratory database present in several Brazilian states. Results of individuals who underwent both genetic testing for lactose intolerance (C/T-13910 polymorphism genotyping) and an LTT from April 2016 until February 2019 were analysed to evaluate agreement between tests. Groups were classified according to age (<10-year-old (yo), 10-17 yo, ≥18 yo groups) and state of residence (São Paulo or Rio Grande do Sul). Results: Among the 404 patients evaluated, there was agreement between the genotyping and LTT results in 325 (80.4%) patients and discordance in 79 (19.6%) patients (k=0.42 -moderate agreement). Regarding the genotype, 47 patients with genotype C/C (lactase nonpersistence) had normal LTT results, and 32 with genotype C/T or T/T (indicating lactase persistence) had abnormal LTT results. Neither age nor state of residence (Rio Grande do Sul or São Paulo) affected the agreement between test results. Conclusion: Considering the moderate agreement between C/T-13910 polymorphism genotyping and LTT results (κ=0.42) in the Brazilian population, we hypothesize that an analysis of other polymorphisms could be a strategy to improve the agreement between genotyping and established tests and suggest that additional studies should focus on exploring this approach.

RESUMO Contexto: O teste de tolerancia à lactose (TTL) é ampliamente utilizado por ser minimamente invasivo e de baixo custo, disponível na atenção primária e muito útil na prática clínica. Está bem estabelecido o polimorfismo C/T-13910 na persistência da lactase em populações caucasianas, mas não há estudos avaliando a concordância entre os resultados da genotipagem do polimorfismo C/T-13910 e do TTL no Brasil, onde a população é altamente miscigenada. Objetivo: Avaliar a concordância entre a presença do polimorfismo C/T-13910 e a má absorção nos resultados do TTL. Métodos: Análise retrospectiva de dados coletados de um laboratorio presente em vários estados brasileiros. Os resultados dos pacientes que realizaram um teste genético para intolerância à lactose (genotipagem do polimorfismo C/T-13910) e um TTL de abril de 2016 a fevereiro de 2019 foram analisados para avaliar a concordância entre os testes. Os grupos foram classificados de acordo com a idade (<10 anos; 10-17 anos, ≥18 anos) e estado de residência (São Paulo ou Rio Grande do Sul). Resultados: Entre os 404 pacientes avaliados, houve concordância entre os resultados de genotipagem e TTL em 325 (80,4%) pacientes e discordância em 79 (19,6%) pacientes (K=0,42 - concordância moderada). Em relação ao genótipo, 47 pacientes com genótipo C/C (não persistência de lactase) apresentaram TTL normal e 32 com genótipo C/T ou T/T (indicando persistência da lactase) apresentaram TTL anormal. A idade e o estado de residência (Rio Grande do Sul ou São Paulo) não afetaram a concordância entre os resultados dos exames. Conclusão: Considerando a concordância moderada entre a genotipagem do polimorfismo C/T-13910 e os resultados de TTL (κ=0,42) na população brasileira, sugerimos que a análise de outros polimorfismos poderia ser uma estratégia para melhorar a concordância entre os testes.

Factors related to non-adherence to cardiac rehabilitation in patients with heart failure.

INTRODUCTION: In heart failure, cardiac rehabilitation has been recommended as an intervention strategy that improves functional capacity, health-related quality of life and survival. However, adherence to these programs is low. The objective was to determine the factors related to non-adherence to cardiac rehabilitation in patients with heart failure in Colombia. METHOD: Observational and retrospective study. Patients with heart failure were linked in a clinic in Colombia, adherence to cardiac rehabilitation was measured with ≥80% of scheduled sessions. Sociodemographic and clinical variables, functional aerobic capacity (Sit to Stand and 6-minute walk test), Duke Activity Status Index (DASI), quality of life Minnesota Living with Heart Failure Questionnaire (MLFHQ) and depression Patient health questionnaire 9 (PHQ-9) were taken into account. RESULTS: 300 patients were linked with heart failure with age 63.16 ± 12.87 men 194 (64.7%). adherence to cardiac rehabilitation was 66.67%, there were statistically significant differences between the groups in arterial hypertension, LVEF, cholesterol, LDL, Triglycerides, SBP, DBP, distance traveled, VO2e, METs, DASI and PHQ-9 p-value =<0.05. The logistic regression model adjusted for sex and age showed OR for non-adherence to CR arterial hypertension 2.23[1.22-4.07], LDL outside of goals 2.15[1.20-3.88], triglycerides outside goals 2.34[1.35-4.07], DASI<4METs 2.38 [1.04-5.45] and PHQ-9 1.06[1.00-1.12]. CONCLUSION: High blood pressure, LDL, triglycerides, DASI and depression with the PHQ-9 questionnaire are related factors for not having adherence to cardiac rehabilitation in patients with heart failure.

Validity of the Functional Assessment of Chronic Illness Therapy Fatigue Scale (FACIT-F) in individuals with Chronic Obstructive Pulmonary Disease in Brazil / Validación de la Escala de Fatiga, Functional Assessment Of Chronic Illness Therapy Fatigue Scale (FACIT-F) en individuos con enfermedad pulmonar obstructiva crónica en Brasil / Validade da Escala de Fadiga, Functional Assessment Of Chronic Illness Therapy Fatigue Scale (FACIT-F) em indivíduos com Doença Pulmonar Obstrutiva Crônica no Brasil

ABSTRACT Fatigue is one of the most prevalent symptoms in individuals with Chronic Obstructive Pulmonary Disease (COPD), but it is poorly evaluated. The Functional Assessment of Chronic Illness Therapy Fatigue Scale (FACIT-F) is one of the main instruments used to measure fatigue. However, this instrument has not yet been validated for the Brazilian population with COPD. This study aimed to investigate the validity of the FACIT-F fatigue scale in individuals with COPD. In a cross-sectional study, the impact of symptoms (COPD Assessment Test - CAT), dyspnea (modified Medical Research Council - MRC scale), functional capacity (six-minute step test - 6MST), exertional fatigue (Borg modified scale at the end of 6MST), and the FACIT-F scale to assess multidimensional fatigue were evaluated. Concurrent validity was assessed by associating the FACIT-F with the CAT, and convergent validity by associating it with the number of steps, perceived exertional fatigue, and dyspnea. Discriminant validity was assessed by comparing fatigue with the dyspnea severity strata. In total, 92 participants were studied (69.9±8.8 years, FEV1: 48.4% of predicted). The FACIT-F presented an average of 30.1±10.9 points, strong concurrent validity with the CAT (r=-0.80), strong convergent validity with dyspnea (r=−0.66), and low with exercise capacity (r=0.40) and fatigue on exertion (r=-0.44). FACIT-F was effective in discriminating groups with different intensities of dyspnea. Conclusion: The FACIT-F is a valid tool for assessing fatigue in the Brazilian population with COPD.

RESUMEN La fatiga es uno de los síntomas más frecuentes en los individuos con enfermedad pulmonar obstructiva crónica (EPOC), pero su evaluación sigue siendo deficiente. Uno de los principales instrumentos utilizados para medir la fatiga es la Functional assessment of chronic illness therapy fatigue scale (FACIT-F). Sin embargo, este instrumento aún no ha sido validado para la población con EPOC en Brasil. En este contexto, el objetivo de este estudio fue investigar la validez de la escala de fatiga FACIT-F en individuos con EPOC. El estudio transversal evaluó el impacto de los síntomas (COPD Assessment Test -CAT), de la disnea (escala modificada del Consejo de Investigación Médica -MRC), de la capacidad funcional (prueba de pasos de seis minutos -6MST), de la fatiga de esfuerzo (escala modificada de Borg al final de la 6MST) y de la escala FACIT-F para evaluar la fatiga multidimensional. La validez concurrente se evaluó asociando la escala con el CAT, y la validez convergente la asoció con el número de pasos, la fatiga al esfuerzo percibida y la disnea. La validez discriminante se evaluó comparando la fatiga con los estratos de gravedad de la disnea. Se estudió a 92 participantes (69,9±8,8 años, VEF1: 48,4% del predicho). La FACIT-F tuvo una puntuación media de 30,1±10,9, fuerte validez concurrente con el CAT (r=-0,80), fuerte validez convergente con la disnea (r=-0,66) y baja con la capacidad de ejercicio (r=0,40) y con la fatiga de esfuerzo (r=-0,44). La FACIT-F fue eficaz para distinguir grupos con diferentes intensidades de disnea, por lo que muestra ser un instrumento válido para evaluar la fatiga en la población brasileña con EPOC.

RESUMO A fadiga é um dos sintomas mais prevalentes nos indivíduos com Doença Pulmonar Obstrutiva Crônica (DPOC), porém, ainda é pouco avaliada. Um dos principais instrumentos utilizados para mensurar a fadiga é a functional assessment of chronic illness therapy fatigue scale (Facit-F). Entretanto, este instrumento ainda não foi validado para a população com DPOC no Brasil. Dessa forma, o objetivo deste estudo foi investigar a validade da escala de fadiga Facit-F em indivíduos com DPOC. Em um estudo transversal, foram avaliados o impacto dos sintomas (COPD Assessment Test - CAT), a dispneia (escala do Medical Research Council - MRC modificada), a capacidade funcional (teste do degrau de seis Minutos - TD6), a fadiga no esforço (escala de Borg modificada ao final do TD6) e a escala Facit-F para avaliar a fadiga multidimensional. A validade concorrente foi avaliada pela associação da escala com o CAT, e a validade convergente pela associação desta com o número de degraus, percepção de fadiga no esforço e a dispneia. A validade discriminante foi avaliada comparando a fadiga com os estratos da gravidade da dispneia. Foram estudados 92 participantes (69,9±8,8 anos, VEF1: 48,4% do previsto). A Facit-F apresentou uma média de 30,1±10,9 pontos, validade concorrente forte com o CAT (r=-0,80), validade convergente forte com a dispneia (r=-0,66) e baixa com a capacidade de exercício (r=0,40) e com a fadiga ao esforço (r=-0,44). A Facit-F foi eficaz em discriminar grupos com diferentes intensidades de dispneia, portanto é um instrumento válido para a avaliação da fadiga na população brasileira com DPOC.

Recuperación de la frecuencia cardíaca en pacientes con enfermedad pulmonar intersticial difusa

Introducción: La enfermedad pulmonar intersticial difusa no soporta el ejercicio, debido a la sensación de disnea y fatiga durante el esfuerzo de baja intensidad. La recuperación de la frecuencia cardíaca se relaciona con el desempeño en el test de caminata de los seis minutos. Objetivo: Determinar las diferencias sociodemográficas de la función y la capacidad pulmonar en pacientes con enfermedad intersticial difusa, a partir de la recuperación de la frecuencia cardíaca durante el test de caminata de los seis minutos. Métodos: Se realizó un estudio descriptivo de corte transversal. Se calculó la recuperación de la frecuencia cardíaca a partir de la diferencia entre el final del test y los cinco minutos de la prueba. Se conformaron dos grupos de comparación, anormal versus normal, en variables sociodemográficas de la función pulmonar y la capacidad funcional. Resultados: Se vincularon 38 pacientes en el grupo normal y en el anormal 26. En el primero predominaron la edad de 62,26 ± 15,82 y los hombres (52,6 %); mientras que en el grupo anormal los años promediaron entre 58,77 ± 13,23 y sobresalieron las mujeres (61,5 %). Se presentó un valor p < 0,05 del grupo recuperación de la frecuencia anormal en la distancia recorrida, disnea y fatiga al final, un minuto y a los cinco minutos de culminar el test. Conclusiones: Los pacientes con enfermedad pulmonar intersticial difusa con una recuperación de la frecuencia cardíaca anormal presentaron peores resultados en la distancia recorrida, volumen de oxígeno, los equivalentes metabólicos, disnea y fatiga de los miembros inferiores.

Introduction: Diffuse interstitial lung disease does not tolerate exercise, due to the sensation of dyspnea and fatigue during low-intensity exertion. Heart rate recovery is related to performance in the six-minute walk test. Objective: To determine sociodemographic differences in lung function and capacity in patients with diffuse interstitial lung disease, based on heart rate recovery during the 6-minute walk test. Methods: A descriptive cross-sectional study was performed. Heart rate recovery was calculated from the difference between the end of the test and the five minutes of the test. Two comparison groups were formed, abnormal versus normal, in sociodemographic variables of pulmonary function and functional capacity. Results: 38 patients were included in the normal group and 26 in the abnormal group. In the normal group, age was 62.26 ± 15.82 and men were predominant (52.6 %); while in the abnormal group, age averaged 58.77 ± 13.23 and women were predominant (61.5 %). A p-value < 0.05 of the abnormal frequency recovery group was presented in the distance run, dyspnea at the end, fatigue at the end, 1 minute and at 5 minutes after the culmination of the test. Conclusions: Patients with diffuse interstitial lung disease with abnormal heart rate recovery had worse results in distance run, oxygen volume, metabolic equivalents, dyspnea and lower limb fatigue.

Avaliação Cardiodinâmica Não Invasiva por Cardiografia de Impedância durante o Teste de Caminhada de Seis Minutos em Pacientes com Insuficiência Cardíaca / Non-Invasive Assessment of Cardiodynamics by Impedance Cardiography during the Six-Minute Walk Test in Patients with Heart Failure

Resumo Fundamento O Teste de Caminhada de seis Minutos (TC6M) é comumente usado para avaliar pacientes com insuficiência cardíaca. No entanto, vários fatores clínicos podem influenciar a distância percorrida pelos pacientes no teste. A cardiografia de impedância (CI) na avaliação morfológica é uma ferramenta útil para avaliar a hemodinâmica cardíaca de maneira não invasiva. Objetivo Este estudo teve como objetivo comparar as respostas de aceleração e desaceleração do Débito Cardíaco (DC), da Frequência Cardíaca (FC), e do Volume Sistólico (VS) ao TC6M de indivíduos com insuficiência cardíaca e fração de ejeção reduzida (ICFEr) com as de controles sadios. Métodos Este é um estudo transversal observacional. O DC, a FC, o VS e o Índice Cardíaco (IC) foram avaliados antes, durante e após o TC6M por CI. O nível de significância adotado na análise estatística foi 5%. Resultados Foram incluídos 27 participantes (13 com ICFEr e 14 controles sadios). A aceleração do DC e da FC foi significativamente diferente entre os grupos (p<0,01 e p=0,039, respectivamente). Encontramos diferenças significativas no VS, no DC e no IC entre os grupos (p<0,01). A regressão linear mostrou uma contribuição deficiente do VS à mudança no DC no grupo com ICFEr (22,9% versus 57,4%). Conclusão O principal resultado deste estudo foi o fato de que indivíduos com ICFEr apresentaram valores mais baixos de aceleração do DC e da FC durante o teste de exercício submáximo em comparação a controles sadios. Isso pode indicar um desequilíbrio na resposta autonômica ao exercício nessa condição.

Abstract Background The six-minute walk test (6MWT) is commonly used to evaluate heart failure (HF) patients. However, several clinical factors can influence the distance walked in the test. Signal-morphology impedance cardiography (SM-ICG) is a useful tool to noninvasively assess hemodynamics. Objective This study aimed to compare cardiac output (CO), heart rate (HR), and stroke volume (SV) acceleration and deceleration responses to 6MWT in individuals with HF and reduced ejection fraction (HFrEF) and healthy controls. Methods This is a cross-sectional observational study. CO, HR, SV and cardiac index (CI) were evaluated before, during, and after the 6MWT assessed by SM-ICG. The level of significance adopted in the statistical analysis was 5%. Results Twenty-seven participants were included (13 HFrEF and 14 healthy controls). CO and HR acceleration significantly differed between groups (p<0.01; p=0.039, respectively). We found significant differences in SV, CO and CI between groups (p<0.01). Linear regression showed an impaired SV contribution to CO change in HFrEF group (22.9% versus 57.4%). Conclusion The main finding of the study was that individuals with HFrEF showed lower CO and HR acceleration values during the submaximal exercise test compared to healthy controls. This may indicate an imbalance in the autonomic response to exercise in this condition.

COVID-19 en las embarazadas. Riesgo de las complicaciones durante el embarazo y en el neonato / COVID-19 in pregnant women. Risk of complications during pregnancy and in the newborn

Sobre el tema COVID-19 se han publicado múltiples estudios que reflejan su elevada incidencia, transmisibilidad, morbilidad y mortalidad, con gran repercusión y severidad en los grupos poblacionales de riesgo. El embarazo no escapa a ello, y la inmunosupresión fisiológica que se presenta en esta condición, hace a la gestante y al neonato, ser más susceptibles a las enfermedades infecciosas. El objetivo de esta comunicación es profundizar en la fisiopatología y la repercusión de la enfermedad COVID-19 en las gestantes y el neonato, para mejorar el conocimiento relacionado con el tema, el cual repercutirá en un mejor manejo de estos pacientes. Para ello, se realizó una revisión de investigaciones publicadas en el período comprendido entre enero y diciembre de 2021, en las bases de datos: SciELO, SCOPUS, Medline, Dialnet, Cumed y Lilacs. De los 44 artículos obtenidos inicialmente, 33 cumplieron los criterios de inclusión.

Several studies on COVID-19 have been published reflecting its high incidence, transmissibility, morbidity and mortality, with great repercussions and severity in population groups at risk. Pregnancy does not escape from this, and the physiological immunosuppression that occurs in this condition makes the pregnant woman and the newborn more susceptible to infectious diseases. The objective of this communication is to deepen the pathophysiology and the repercussion of the COVID-19 disease in pregnant women and the newborn in order to improve knowledge related to the subject, which will have an impact on better management of these patients. For this, a review of research published between January and December 2021 was carried out in the databases such as SciELO, SCOPUS, Medline, Dialnet, Cumed and Lilacs. A number of 33 articles met the inclusion criteria from 44 initially obtained.

Fatores correlacionados a intolerância ao exercício na alta de pacientes hospitalizados por COVID-19 / Factors correlated to exercise intolerance upon discharge in patients hospitalized for COVID-19

Objetivo: Verificar a prevalência da intolerância ao exercício e a correlação com o perfil sociodemográfico, clínico, de hospitalização e função física na alta de pacientes hospitalizados pela COVID-19. Métodos: Estudo transversal com 52 pacientes internados por COVID-19 no Hospital Santa Casa de Misericórdia de Vitória, Espírito Santo. Coletou-se informações no momento da alta quanto ao perfil sociodemográfico, clínico, de hospitalização e função física, através de questionário semiestruturado, prontuário eletrônico, escalas e testes. Utilizou-se o Medical Research Council Modificado (mMRC) para graduar a dispneia, o Medical Research Council (MRC) para avaliar força muscular periférica, a manovacuometria, através das pressões inspiratória e expiratória máximas, para mensurar força muscular respiratória e a Medida de Independência Funcional (MIF) para funcionalidade. A variável desfecho, tolerância ao exercício, foi medida pelo Teste de Sentar e Levantar de 1 minuto. Resultados: Todos participantes apresentaram intolerância ao exercício no momento da alta hospitalar. O desempenho no teste de sentar e levantar foi inversamente correlacionado com o grau de dispneia e diretamente com a força muscular inspiratória, pontuação total da Medida de Independência Funcional, domínios de autocuidado, locomoção, mobilidade (p 0,019), e controle de esfíncter Conclusão: A prevalência da intolerância ao exercício na alta por COVID-19 foi de 100%, e estava correlacionada com o grau de dispneia, força muscular inspiratória e funcionalidade para autocuidado, locomoção, mobilidade e controle de esfíncter. Destaca-se a avaliação da tolerância ao exercício como importante preditor de sequelas pós-COVID-19, capaz de avaliar a interação entre diversos sistemas orgânicos.

Objective: To verify the prevalence of exercise intolerance and the correlation with the sociodemographic, clinical, hospitalization and physical function profile at discharge of patients hospitalized for COVID-19. Methods: Cross-sectional study with 52 patients hospitalized for COVID-19 at Hospital Santa Casa de Misericórdia in Vitória, Espírito Santo. Information was collected at discharge regarding the sociodemographic, clinical, hospitalization and physical function profile, through a semi-structured questionnaire, electronic medical record, scales and tests. The Modified Medical Research Council (mMRC) was used to grade dyspnea, the Medical Research Council (MRC) was used to assess peripheral muscle strength, manovacuometry, through maximal inspiratory and expiratory pressures, to measure respiratory muscle strength and the Independence Measure Functional (MIF) for functionality. The outcome variable, exercise tolerance, was measured by the 1-minute Sit and Stand Test. Results: All participants presented exercise intolerance at discharge. Performance in the 1-minute Sit and Stand Test was inversely correlated with the degree of dyspnea and directly with inspiratory muscle strength, total score on the Independence Measure Functional, self-care domains, locomotion, mobility and sphincter control. Conclusion: The prevalence of exercise intolerance at discharge due to COVID-19 was 100%, and was correlated with the degree of dyspnea, inspiratory muscle strength and functionality for self-care, locomotion, mobility and sphincter control. The assessment of exercise tolerance stands out as an important predictor of sequelae after COVID-19, capable of assessing the interaction between different

Dexmedetomidine, an α2 agonist, increases the morphine analgesic effect and decreases morphine tolerance development by suppressing oxidative stress and TNF/IL-1 signalling pathway in rats.

BACKGROUND: The aim of the present study is to examine the possible effect de dexmedetomidine on the development of morphine tolerance in rats including nociception, morphine analgesia, apoptosis, oxidative stress, and tumour necrosis factor (TNF)/ interleukin-1 (IL-1) pathways. MATERIALS AND METHODS: In this study, 36 Wistar Albino (225-245 g) rats were used. Animals were divided into 6 groups: saline (S), 20 mcg/kg dexmedetomidine (D), 5 mg/kg morphine (M), M + D, morphine tolerance (MT), and MT + D. The analgesic effect was measured with hot plate and tail-flick analgesia tests. After the analgesia tests, the dorsal root ganglia (DRG) tissues were excised. Oxidative stress parameters [total antioxidant status (TAS), total oxidant status (TOS)], TNF, IL-1 and apoptosis enzymes (Caspase-3, Caspase-9), were measured in DRG tissues. RESULTS: Dexmedetomidine showed an antinociceptive effect when given alone (p < 0.05 to p < 0.001). In addition, dexmedetomidine increased the analgesic effect of morphine (p < 0.001), and also decreased the tolerance to morphine at a significant level (p < 0.01 to p < 0.001). Moreover, it decreased oxidative stress (p < 0.001) and TNF/IL-1 levels when given as an additional drug of single-dose morphine and morphine tolerance group (p < 0.001). Furthermore, dexmedetomidine decreased Caspase-3 and Caspase-9 levels after tolerance development (p < 0.001). CONCLUSION: Dexmedetomidine has antinociceptive properties, and it increases the analgesic effect of morphine and also prevents tolerance development. These effects probably occur by the modulation of oxidative stress, inflammation and apoptosis.

La prueba cardiopulmonar de ejercicio contribuye a determinar con precisión el riesgo en pacientes con hipertensión pulmonar de bajo riesgo / Cardiopulmonary Exercise Testing Contributes to Accurate Risk Assessment in Patients with Low-risk Pulmonary Hypertension

RESUMEN Introducción : Las guías europeas de hipertensión arterial pulmonar (HAP) estratifican el riesgo valiéndose de características clínicas y estudios complementarios entre los cuales está la prueba cardiopulmonar de ejercicio (PCPE), de la cual toma en cuenta 3 parámetros: el consumo de O2 (VO2) pico, su porcentaje respecto del predicho y la pendiente ventilación minuto/ producción de dióxido de carbono (VE/VCO2). Sin embargo, ninguno de los modelos que validaron esta forma de estratificar el riesgo incluyeron la PCPE entre sus variables. Objetivos : Determinar qué proporción de pacientes con HAP del grupo I considerados de bajo riesgo y que caminan >440 metros en la prueba de caminata de 6 minutos (PC6M) tienen en la PCPE parámetros considerados de riesgo moderado o alto. Material y métodos : Se incluyeron pacientes >18 años con diagnóstico de HAP del grupo I considerados de bajo riesgo con una PC6M >400 metros a los que se les realizó una PCPE en la que se registró el VO2 pico, su porcentaje respecto del VO2 predicho y la pendiente VE/VCO2. Se determinó qué proporción de pacientes presentaban estos parámetros en un estrato de riesgo mayor a bajo riesgo (VO2 pico <15 ml/kg/min, su porcentaje respecto del predicho <65% y la pendiente VE/VCO2 >36). Resultados : Se incluyeron 18 pacientes. A pesar de ser pacientes de bajo riesgo y con buena clase funcional todos presentaron un VO2 pico menor al 85% del predicho, lo cual determina un deterioro al menos leve de la capacidad funcional. Un único paciente (6%) presentó los tres parámetros evaluados en bajo riesgo, 8 pacientes (44%) tuvieron al menos un parámetro alterado, 7 pacientes (39%) presentaron 2 parámetros alterados y en 2 pacientes (11%) todos los parámetros estuvieron alterados. Los parámetros que más frecuentemente se vieron alterados fueron el porcentaje respecto del VO2 predicho y la pendiente VE/VCO2, en el 67% de los casos. Solo 4 pacientes presentaron un VO2 pico <15 ml/k/m. Ningún paciente presentó valores de VO2 pico o porcentaje respecto del predicho en la categoría de alto riesgo. Sin embargo, 6 pacientes (33%) presentaron una pendiente VE/VCO2 considerada de alto riesgo. Conclusión : El 94% de los pacientes considerados de bajo riesgo presentaron al menos una variable en la PCPE que no corresponde a un perfil de riesgo bajo. La pendiente VE/VCO2 y el porcentaje de VO2 pico respecto del predicho fueron las variables más frecuentemente alteradas. La pendiente VE/VCO2 fue la única que mostró valores considerados de alto riesgo. La PCPE podría tener un lugar en la estratificación de precisión de pacientes de bajo riesgo. El valor de este hallazgo deberá ser evaluado en estudios prospectivos, al tiempo que genera las bases para el planteo de hipótesis respecto de la estratificación de riesgo y la intensidad del tratamiento en pacientes que aparentan estar en bajo riesgo.

ABSTRACT Background : European guidelines for pulmonary arterial hypertension (PAH) stratify the risk using clinical characteristics and complementary studies, including the cardiopulmonary exercise test (CPET). This takes into account 3 parameters: peak O2 consumption (peak VO2), its percentage with respect to the predicted VO2, and the minute ventilation/carbon dioxide production (VE/VCO2) slope. However, none of the models that validated this way of stratifying risk included PCPE among their variables. Objectives : To determine what proportion of patients with group I PAH considered to be at low risk and who walk >440 meters in the 6-minute walk test (6MWT) have parameters considered to be of moderate or high risk in the PCPE. Methods : Patients >18 years of age, diagnosed with group I PAH at low risk of events, who walked >440 meters in the 6MWT and had NT-proBNP value <300 pg/dL were included. A CPET was performed in which the peak VO2, its percentage with respect to the predicted VO2, and the VE/VCO2 slope were recorded. It was determined what proportion of patients presented these parameters in a higher than low risk stratum (peak VO2 consumption ≤15 ml/min/Kg, its percentage with respect to the predicted VO2 ≤65% and the VE/VCO2 slope ≥36). Results : Eighteen patients were included. Despite being low-risk patients with a good functional class, all patients presented a peak VO2 less than 85% of predicted, which determines a deterioration of functional capacity. A single patient (6%) presented the three parameters evaluated at low risk, 8 patients (44%) had at least one altered parameter, 7 patients (39%) presented 2 altered parameters and in 2 patients (11%) all parameters were altered. The parameters that were most frequently altered were the percentage of predicted peak VO2 and the VE/VCO2 slope in 67% of the cases. Only 4 patients presented a peak VO2 <15 ml/kg/m. No patient presented peak VO2 values or percentage of predicted VO2 in the high-risk category. However, 6 patients (33%) presented a high-risk VE/VCO2 slope. Conclusion : Majority (92%) of the patients considered low risk and who walk more than 440 meters in 6 minutes presented at least one altered variable in the CPET. The VE/VCO2 slope and the percentage of predicted peak VO2 consumption were the most frequently altered variables. The VE/VCO2 slope was the only one that showed values considered high risk. CPET could have a place in the precision stratification of low-risk patients. The value of this finding should be evaluated in prospective studies.

Evaluating the influence of nature connection and values on conservation attitudes at a tropical deforestation frontier.

Inner phenomena, such as personal motivations for pursuing sustainability, may be critical levers for improving conservation outcomes. Most conservation research and policies, however, focus on external phenomena (e.g., ecological change or economic processes). We explored the factors shaping 9 conservation attitudes toward forest and wildlife protection among colonist farmers around an Amazonian deforestation frontier. Our data comprised 241 face-to-face quantitative surveys, complemented with qualitative insights from open-ended questionnaire responses and opportunistic semistructured interviews. To account for the full spectrum of possible inner motivations, we employed measures of nature connection (indicating biospheric motivation) and personal values organized around the traditionalism (traditionalist through to high openness to change) and universalism dimensions (egoistic through to altruistic motivations). We used averaged beta-binomial generalized linear models to assess the role of external factors (socioeconomic, sociodemographic, and environmental) and personal (inner) motivations on the variation in attitudes. Each attitude was modeled separately. The relative importance of each predictor was judged by the proportion of models where it appeared as significant. Proconservation views were expressed by the majority (at least 65%) of the respondents in 7 out of the 9 attitude models. The most consistent predictors were emotional nature connection and personal values (significant in 4-6 out of 9 models), rather than external phenomena (significant in 0-5 models). However, the poorest farmers had lower scores on the agreement with prioritizing nature over development (𝛽 = -0.52, 95% CI: -0.96 to -0.07). Qualitative data also indicated that economic barriers hinder forest conservation on farms. These results suggest that biospheric, traditionalistic, and altruistic motivations promote people's proconservation attitudes, but nurturing these latent motivations is unlikely to improve conservation outcomes if material poverty remains unaddressed. Integrating the inner-outer perspective into conservation thinking and practical interventions could foster environmental stewardship and increase human well-being.

Evaluación de la influencia de la conexión y los valores naturales sobre las actitudes de conservación es una frontera tropical de deforestación Resumen Los fenómenos interiores, como los motivos personales para ser sustentables, pueden ser niveladores importantes para aumentar los resultados de conservación. Sin embargo, la mayor parte de la investigación y las políticas se enfocan en los fenómenos exteriores (cambios ecológicos o procesos económicos, por ejemplo). Exploramos los factores que moldean nueve actitudes de conservación relacionadas con la protección de los bosques y la fauna en un grupo de agricultores colonos cercanos a una frontera de deforestación en la Amazonía. Nuestros datos se obtuvieron de 241 encuestas presenciales cuantitativas complementadas con información cualitativa tomada de las respuestas en cuestionarios de preguntas abiertas y entrevistas oportunistas semiestructuradas. Para considerar el espectro completo de las posibles motivaciones interiores empleamos medidas de la conexión natural (lo que indica motivos relacionados a la biósfera) y valores personales organizados en torno a las dimensiones del tradicionalismo (del tradicionalista hasta una gran apertura al cambio) y el universalismo (del egoísta hasta los motivos altruistas). Usamos modelos lineales generalizados betabinomiales promediados para evaluar el papel que tienen los factores externos (socioeconómicos, sociodemográficos y ambientales) y los motivos personales (interiores) en la variación de las actitudes. Modelamos cada actitud por separado. Juzgamos la importancia relativa de cada predictor mediante la proporción de modelos en los que aparecían como significativos. La mayoría (al menos el 65%) de los respondientes expresó las opiniones en pro de la conservación en siete de los nueve modelos de actitud. Los predictores más uniformes fueron la conexión emocional natural y los valores personales (significativos en cuatro a seis de los nueve modelos), en lugar de los fenómenos externos (significativos en cero a cinco modelos). Sin embargo, los agricultores más pobres tuvieron un puntaje más bajo en cuanto a estar de acuerdo con la priorización de la naturaleza sobre el desarrollo (𝛽 = -0.52, 95% CI -0.96 a -0.07). Los datos cualitativos también indicaron que las barreras económicas impiden la conservación de los bosques en las fincas. Estos resultados sugieren que los motivos tradicionalistas, altruistas y aquellos relacionados con la biósfera promueven las actitudes en pro de la conservación de las personas, pero es poco probable que propiciar estos motivos latentes aumente los resultados de conservación si sigue sin solucionarse la pobreza material. La inclusión de las perspectivas internas y externas dentro del pensamiento de conservación y las intervenciones prácticas podría fomentar la administración ambiental e incrementar el bienestar humano.

[Influence of physical activity on radiotherapy-treated breast cancer patients: A systematic review]. / Influencia del ejercicio físico sobre los síntomas de la radioterapia en pacientes con cáncer de mama: revisión sistemática.

INTRODUCTION: The number of survivors with cancer is growing worldwide, but the adverse effects of the radiotherapy are still frequent, affecting effort capacity, respiratory function and quality of life. The objective is to know how the physical exercise influences the respiratory function and tolerance to effort, in pacients with breast cancer after the radiotherapy treatment. MATERIALS AND METHODS: The searches were carried out in the databases of Pubmed, PEDro, Web Of Science, Cochrane, EMBASE, UptoDate and Tripdatabase. Were included studies with patients with breast cancer treated with radiotherapy and included in an exercise program. The main results were: maximum oxygen consumption, 6 minutes walking test, forced vital capacity, vital capacity, forced expiratory volume in 1 second, total lounge capacity, inspiratory capacity, and the diffusion capacity of the lungs for carbon monoxide. RESULTS: The results show an increase of the effort capacity with 15% improvements in the maximum oxygen consumption and 6.675% in the 6 minutes walking test, while they are limited for the respiratory function. CONCLUSIONS: The physical exercise is effective for improve the effort capacity in pacients with breast cancer treated with radiotherapy, without changes in the respiratory function. Nevertheless, new studies are necessary to investigate deeply how the physical exercise influences in those pacients, and the ideal design of the programs.

Effect of semantics in the study of tolerance for wolves.

As conservation scholars increasingly recognize the critical role of human thought and behavior in determining the persistence of biodiversity across the globe, a growing line of inquiry regarding the validity and comparability of previous applications of core psychological concepts has emerged. Specifically, inconsistent measurement and use of terms, such as attitudes and acceptance, reveal important questions about previous approaches. Given that these concepts differ by definition, yet have been used interchangeably, we explored what drives differences in people's responses when each concept is operationalized in the context of a contested wildlife species, the gray wolf (Canis lupus). To do so, we used data from a 2014 survey of U.S. residents (n = 1287) to test how measures of six concepts (i.e., acceptance, attitudes, benefits, risks, [prior] behavior, and behavioral intentions) often employed in the conservation social sciences were related with a broad set of possible explanatory variables. Despite moderate to strong correlations between all concepts measured (| Pearson's r | = 0.39-0.65, p < 0.001), results revealed considerable variation in their respective relationships with identical explanatory variables. Specifically, although wildlife value orientation (i.e., domination or mutualism) operated fairly consistently across cognitive and behavioral concepts, the relationship between the six concepts and other factors, such as social trust, identification with various interest groups (i.e., hunter, farmer, or rancher, environmentalist, and animal rights advocate), and political ideology (i.e., liberal vs. conservative), varied considerably. Our findings underscore that differences exist in these measures, which could have serious implications for conservationists integrating social science findings in their decision-making processes if they are unaware of the theoretical underpinnings of and distinctions between core psychological concepts.

Efectos de la semántica en los estudios de tolerancia a los lobos Resumen Los académicos dedicados a la conservación reconocen cada vez más lo importantes que son el pensamiento y el comportamiento humano para definir la persistencia de la biodiversidad a nivel mundial, por lo que ha emergido una creciente línea de indagación con respecto a la validez y la comparabilidad de las aplicaciones previas de conceptos psicológicos fundamentales. Más específicamente, las medidas incompatibles y el uso de términos como actitudes y aceptación revelan preguntas importantes sobre las estrategias anteriores. Ya que estos conceptos difieren por definición y aun así se han usado indistintamente, decidimos explorar qué impulsa las diferencias en las respuestas de las personas cuando cada concepto opera en el contexto de una especie de fauna controvertida: el lobo gris (Canis lupus). Para lograr esto, usamos datos de un censo de 2014 aplicado a residentes estadunidenses (n = 1,287) para analizar cómo la medida de seis conceptos usados frecuentemente en las ciencias sociales de la conservación (aceptación, actitudes, beneficios, riesgos comportamiento [previo] e intenciones conductuales) se relacionan con un amplio conjunto de variables explicativas posibles. A pesar de las correlaciones moderadas y fuertes entre todos los conceptos medidos (| Pearson's r | = 0.39 a 0.65, p < 0.001), los resultados revelaron una variación considerable en sus respectivas relaciones con las variables explicativas idénticas. De manera más precisa, aunque la orientación del valor de la fauna (es decir, dominancia y mutualismo) operó uniformemente en los conceptos cognitivos y conductuales, la relación entre los seis conceptos y otros factores, como la confianza social, identificación con varios grupos de interés (cazador, agricultor o ranchero, ambientalista, defensor de los derechos animales) e ideología política (liberal vs conservador) variaron considerablemente. Nuestros resultados destacan las diferencias que existen en estas medidas, las cuales podrían tener repercusiones serias para los conservacionistas que integran los resultados de las ciencias sociales dentro de sus procesos de toma de decisiones si no están concientes de las teorías fundamentales y las distinciones entre los conceptos psicológicos fundamentales.

Actualización en fibrosis quística: diabetes relacionada a fibrosis quística en la era de los moduladores del regulador de transmembrana de fibrosis quística (CFTR) / Update on cystic fibrosis/cystic fibrosis related diabete in the era of transmembrane regulator in cystic fibrosis (CFTR)

Las disglicemias, objetivadas en el test de tolerancia a la glucosa de 2 horas y en el monitoreo continuo de glicemia, son el factor de riesgo principal para el desarrollo de la diabetes relacionada a fibrosis quística (FQ) (DRFQ), la que constituiría la etapa final de un continuo de alteraciones del metabolismo de la glucosa en los pacientes con FQ. Estas disglicemias se deben tanto al daño directo de las células de los islotes pancreáticos productores de insulina, como al aumento de la resistencia a la insulina asociada al estado inflamatorio sistémico de la FQ. El uso cada vez más precoz de los moduladores del CFTR debiera contribuir a evitar el desarrollo de DRFQ y sus complicaciones. La siguiente revisión se enfoca en los efectos de los moduladores del CFTR en la tolerancia a la glucosa en pacientes con FQ.

Dysglycemia, observed in the 2-hour glucose tolerance test and in the continuous monitoring of glycemia, are the main risk factor for the development of diabetes related to cystic fibrosis (CF), which constitutes the final stage of a continuum of impaired glucose metabolism in people with CF. These dysglycemias are due both to direct damage to insulin-producing pancreatic islet cells, and to increased insulin resistance associated with the systemic inflammatory state of CF. The increasingly early use of CFTR modulators should help prevent the development of CRFD and its complications. The following review focuses on the effects of regulador de transmembrana de fibrosis quística (CFTR) modulators on glucose tolerance in people with CF.
