ABSTRACT

Abstract Objective: This study evaluates the effects of sarcopenia and cachexia on the quality of life (QoL) of patients with gastrointestinal cancer during their initial cycle of chemotherapy, emphasizing the significance of computed tomography (CT) in assessing muscle mass. Materials and Methods: In this prospective study, we evaluated 60 adult patients with gastrointestinal cancer who started chemotherapy between January and December of 2017. Sarcopenia was diagnosed on the basis of CT findings, and QoL was assessed with the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core 30. Results: The mean age was 60.9 years, and 33 (55.0%) of the patients were men. Of the 60 patients, 33 (55.0%) had cachexia and 14 (23.3%) had sarcopenia. Chemotherapy significantly reduced QoL, particularly in the physical, role functioning, and social domains, with no differences between the cachexia and sarcopenia groups. Conclusion: Among patients with gastrointestinal cancer submitted to chemotherapy, the chemotherapy-induced decline in QoL does not seem to differ significantly between those with cachexia or sarcopenia, as classified by CT-measured muscle mass, and those without. However, CT-based muscle mass evaluation remains crucial for guiding customized intervention strategies. Integrating this evaluation in radiological reports can provide valuable insights for planning specific care, thus improving patient QoL during treatment.


Resumo Objetivo: Este estudo avalia os efeitos da sarcopenia e da caquexia na qualidade de vida de pacientes com câncer gastrointestinal durante o ciclo inicial de quimioterapia, enfatizando a importância da tomografia computadorizada (TC) na avaliação da massa muscular. Materiais e Métodos: Estudo prospectivo com 60 pacientes adultos com câncer gastrointestinal que iniciaram quimioterapia de janeiro a dezembro de 2017. A TC foi utilizada para o diagnóstico de sarcopenia e o Quality of Life Questionnaire Core 30 da European Organization for Research and Treatment of Cancer foi utilizado para avaliar a qualidade de vida. Resultados: A média de idade dos pacientes foi 60,9 anos e 33 (55%) eram homens. Entre os pacientes, 33 (55%) eram caquéticos e 14 (24%) eram sarcopênicos. A quimioterapia reduziu significativamente a qualidade de vida, especialmente nos domínios físico, de desempenho de papéis e social, sem diferenças entre os grupos caquéticos e sarcopênicos. Conclusão: A diminuição da qualidade de vida não difere significativamente entre pacientes caquéticos/sarcopênicos e não caquéticos/não sarcopênicos com câncer gastrointestinal submetidos a quimioterapia, conforme classificado pela massa muscular medida por TC. No entanto, a avaliação da massa muscular por TC continua crucial para orientar estratégias de intervenção personalizadas. A integração dessa avaliação nos laudos radiológicos pode fornecer informações valiosas para o planejamento de cuidados específicos, melhorando a qualidade de vida dos pacientes durante o tratamento.

ABSTRACT

ObjectiveTo investigate the value of L3 skeletal muscle index (L3-SMI) combined with interleukin-6 (IL-6) and activin A in predicting early-stage pancreatic cancer cachexia. MethodsA total of 74 patients with pancreatic cancer who were diagnosed in Hebei Medical University Forth Hospital from July 2020 to July 2023 were enrolled, and according to the presence or absence of cachexia after admission, the patient were divided into cachexia group with 58 patients and non-cachexia group with 16 patients. The levels of L3-SMI, IL-6, and activin A were observed within 48 hours after admission. The independent-samples t test was used for comparison of normally distributed continuous data between groups, and the chi-square test was used for comparison of categorical data between groups. A multivariate Logistic regression analysis was used to investigate the influencing factors for pancreatic cancer cachexia; the receiver operating characteristic (ROC) curve was used to analyze the value of L3-SMI, IL-6, and activin A alone or in combination in predicting pancreatic cancer cachexia, and the Z test was used for comparison of the area under the ROC curve (AUC). ResultsCompared with the non-cachexia group, the cachexia group had a significantly higher level of L3-SMI and significantly lower serum levels of IL-6 and activin A (t=8.649, 3.049, and 8.100, all P<0.05). The multivariate logistic analysis showed that L3-SMI (odds ratio [OR]=0.266, 95% confidence interval [CI]: 0.103‍ ‍—‍ ‍0.683, P<0.05), serum IL-6 (OR=4.158, 95%CI: 1.368‍ ‍—‍ ‍12.333, P<0.05), and activin A (OR=5.124, 95%CI: 1.550‍ ‍—‍ ‍16.939, P<0.05) were influencing factors for pancreatic cancer cachexia. L3-SMI, IL-6, and activin A alone had a significantly lower AUC than the combination of the three indicators in predicting pancreatic cancer cachexia (0.851/0.752/0.791 vs 0.946, Z=-2.841, -2.552, and -2.647, all P<0.001), and the combination of the three indicators had the highest sensitivity (90.9%), specificity (87.8%) and Youden index (0.788). ConclusionL3-SMI combined with serum IL-6 and activin A has a good value in predicting early-stage pancreatic cancer cachexia.

ABSTRACT

RESUMEN La estrongiloidiasis comúnmente produce problemas gastrointestinales. Presentamos el caso de un varón, cadete en la marina de guerra del Perú, de 30 años, procedente de lima; que desarrolló síndrome de hiperinfección por Strongyloides Stercoralis, teniendo como antecedente el diagnóstico presuntivo de polimiositis, por lo cual recibió un ciclo corto de corticoesteroides. No portador del virus htlv 1/2. Presentó al ingreso hiporexia, debilidad generalizada, caquexia, diarrea intermitente autolimitada, intolerancia oral y leve distensión abdominal. El paciente llegó a la etapa de diseminación, lo que resultó en un daño severo a nivel intestinal. La baja excreción de larvas en las heces dificultó el diagnóstico. Se brindó tratamiento con ivermectina parenteral a dosis de 1.2ml vía subcutánea cada 48 horas por tres dosis, con buena respuesta clínica y posteriormente con buena tolerancia oral. La importancia de presentar el caso es comentar sobre el abordaje diagnóstico y terapéutico de esta geohelmintiasis endémica del Perú.


Abstract Strongyloidiasis commonly causes gastrointestinal problems. We present the case of a male, a 30-year-old cadet in the peruvian navy from lima, who developed a hyperinfection syndrome due to strongyloides stercoralis, having a presumptive diagnosis of polymyositis for which he received a short cycle of corticosteroids. He was not a carrier of the htlv 1/2 virus. Upon admission, he presented with hyporexia, generalized weakness, cachexia, intermittent self-limited diarrhea, oral intolerance, and mild abdominal distension. The patient reached the dissemination stage, resulting in severe intestinal damage. The low excretion of larvae in the feces made the diagnosis difficult. Treatment was provided with parenteral ivermectin at a dose of 1.2ml subcutaneously every 48 hours for three doses, with a good clinical response and subsequently good oral tolerance. The importance of presenting the case is to comment on the diagnostic and therapeutic approach to this endemic geohelminthiasis of peru.

ABSTRACT

OBJECTIVE To investigate the improvement effects and mechanism of imperatorin on cachexia model mice. METHODS Fifteen male C57BL/6J mice were randomly divided into blank control group, model group and imperatorin group, with 5 mice in each group. Except for blank control group, the remaining mice were inoculated with LLC cell suspension subcutaneously on the dorsal surface, and the drug was administered by gavage daily from the 7th day of inoculation. The imperatorin group was gavaged with imperatorin suspension (0.5% sodium carboxymethylcellulose solution as solvent) at 60 mg/kg; blank control group and model group were given an equal volume of 0.5% sodium carboxymethylcellulose solution, for 13 d of continuous administration. During the administration period, food intake and body mass of mice were recorded daily and regularly, tumor long and short diameters were measured every two days, and tumor volume was calculated. The skeletal muscle mass and tumor mass of each group were weighed and the tumor-free body weight was calculated; the pathological changes of skeletal muscle were observed and the cross-sectional area of skeletal muscle fibers was calculated; the phosphorylation levels of signal transduction and activator of transcription 3 (STAT3) (measured as p-STAT3/STAT3 ratio), muscle atrophy box F gene (MAFbx), myostatin (Myog), B-cell lymphoma-2 (Bcl-2), Bcl-2 associated X protein (Bax), Caspase3 protein and mRNA expression were all detected. RESULTS Compared with blank control group, body mass and skeletal muscle mass of model group were decreased significantly (P<0.05), and reduced food intake, loose arrangement of skeletal muscle, large cell space were observed; the cross-sectional area of skeletal muscle fiber was significantly reduced, while p-STAT3/STAT3 ratio, protein and mRNA expressions of MAFbx, Bax and Caspase3 were somo_amour@163.com increased significantly (P<0.05). The protein and mRNA expressions of Myog and Bcl-2 were significantly reduced (P< 0.05). Compared with model group, body weight, tumor-free weight and skeletal muscle weight were increased significantly in imperatorin group (P<0.05); food intake increased, while the expressions of tumor weight and volume were decreased significantly (P<0.05); the expressions of above proteins and genes were improved significantly (P<0.05). CONCLUSIONS Imperatorin can improve the tumor cachexia state, the mechanism of which may be related to the regulation of ubiquitin-proteasome pathway and anti-apoptosis.

ABSTRACT

Cancer anorexia/cachexia syndrome (cancer anorexia cachexia syndrome, CACS) is a common complication in advanced cancer patients, which is characterized by reduced feeding, sustained weight loss, general fatigue and weakness. CACS related symptoms make patients suffer from a series of adverse psychosocial effects, such as anxiety, pain and social isolation, thus bringing serious adverse effects on patients′ individuals, families and society. This paper reviewed the symptoms associated with CACS and their psychosocial effects, as well as the interventions related to adverse psychosocial effects, in order to provide theoretical reference for alleviating psychosocial distress and improving health-related quality of life of patients with CACS.

ABSTRACT

Cancer cachexia is a multifactorial syndrome characterized by the continuous loss of skeletal muscle. The pathogenic mechanism of cancer cachexia remains unknown, and the effectiveness of routine nutritional therapy is limited. The mitochondrial disorder is demonstrated to play an important role in the mechanism of tumor-induced skeletal muscle atrophy, including alterations to the mitochondrial ultrastructure, biogenesis, dynamics, mitophagy, and functions. Interventions targeting mitochondrial alterations provide a potential solution to cancer cachexia and represent a new focus in this research field.

ABSTRACT

Objective:To establish a mouse model representing the cardinal features of pancreatic ductal adenocarcinoma-induced cachexia, and to investigate the changes in phenotype, metabolism and cachexia-related biomarkers.Methods:BALB/c nude mice were randomly divided into control group ( n=6) and tumor group ( n=6). The cachexia model of pancreatic cancer was established in BALB/c nude mice by intraperitoneal injection of Panc01 cell line. The changes in body weight, food intake, grip strength and body composition were recorded over the course of tumor development. The animals were euthanized after 2 weeks and were examined for intraperitoneal metastasis. Quantitative real-time polymerase chain reaction was used to detect the expression of cachexia related genes in muscle and adipose tissue and the expression of related inflammatory factors in peripheral blood. Results:The animals in tumor group showed an obvious cachexia phenotype, which was manifested by decreased food intake, lean body weight, and grip strength, and enhanced muscle catabolism. The wasting syndrome in this model was accompanied by hypothalamic inflammation and upregulated expression of uncoupling protein 1 (Ucp1) in white adipose tissue. Haematological abnormalities included leukocytosis and anemia.Conclusions:Intraperitoneal injection of human pancreatic cancer cell Panc01 into nude mice is a reliable model for the study of cachexia, which recapitulates the key features of the pancreatic cancer progress and induces a wide array of cachexia manifestations. Therefore, this model is suitable for preclinical researches exploring the mechanism of cachexia related to pancreatic cancer and identifying novel therapies.

ABSTRACT

Resumo Fundamento Problemas nutricionais são comuns em pacientes com insuficiência cardíaca (IC) e estão associados a um prognóstico ruim. É relevante mencionar que algumas populações de pacientes, como os com Doença de Chagas, são normalmente excluídas da maioria das análises. Objetivo Buscamos analisar a ocorrência de desnutrição e caquexia em pacientes com Doença de Chagas durante episódios de IC descompensada (ICD) em comparação a outras etiologias, e investigar a influência desses achados em desfechos hospitalares. Método Realizamos um estudo de série de casos consecutivos com pacientes hospitalizados com ICD. Os pacientes foram submetidos à Avaliação Nutricional Subjetiva Global (ASG), além de medidas antropométricas e laboratoriais, e foram avaliados para a ocorrência de caquexia, baixa massa muscular e força. Estudamos a ocorrência de morte e transplante cardíaco de urgência durante a internação. Resultados Ao todo, 131 pacientes foram analisados e 42 (32,1%) tinham Doença de Chagas. Pacientes com Doença de Chagas apresentavam índice de massa corporal (IMC) menor (22,4 kg/m2 [19,9-25,3] vs. 23,6 kg/m2 [20,8-27,3], p=0,03), maior frequência de desnutrição (76,2% vs 55,1%, p=0,015) e mais ocorrências de morte ou transplante (83,3% vs. 41,6%, p<0,001). Observamos que, dentre os pacientes com etiologia da Doença de Chagas, a ocorrência de morte ou transplante cardíaco esteve associada com desnutrição (3 [42,9%] pacientes com alta hospitalar vs. 29 [82,9%] pacientes que morreram ou receberam transplante cardíaco, P=0,043). Conclusões Ao todo, nossos resultados indicam que pacientes com Doença de Chagas internados com ICD costumam apresentar problemas nutricionais, principalmente desnutrição. É importante mencionar que este achado esteve associado à ocorrência de morte e transplante cardíaco durante a internação.


Abstract Background Nutritional disorders are common among patients with heart failure (HF) and associated with poor prognosis. Importantly, some populations of patients, like the ones with Chagas disease, are frequently excluded from most analyses. Objective We sought to study the occurrence of undernutrition and cachexia in patients with Chagas disease during episodes of decompensated HF (DHF) as compared to other etiologies, and to investigate the influence of these findings on hospital outcomes. Methods We performed a consecutive case series study with patients hospitalized with DHF. Patients underwent the Subjective Global Assessment of nutritional status (SGA), besides anthropometric and laboratorial measures, and were evaluated for the occurrence of cachexia, low muscle mass and strength. We studied the occurrence of death or urgent heart transplantation during hospitalization. Results Altogether, 131 patients were analyzed and 42 (32.1%) had Chagas disease. Patients with Chagas disease had lower Body Mass Index (BMI) (22.4 kg/m2[19.9-25.3] vs. 23.6 kg/m2 [20.8-27.3], p=0.03), higher frequency of undernutrition (76.2% vs 55.1%, p=0.015) and higher occurrence of death or transplant (83.3% vs. 41.6%, p<0.001). We found that, in patients with Chagas etiology, the occurrence of death or cardiac transplantation were associated with undernutrition (3 [42.9%] patients with hospital discharge vs 29 [82.9%] patients with death or heart transplant, p=0.043). Conclusions Taken together, our results indicate that patients with Chagas disease hospitalized with DHF often present with nutritional disorders, especially undernutrition; importantly, this finding was associated with the occurrence of death and heart transplant during hospitalization.

ABSTRACT

Cachexia is a common complication in patients with lung cancer. It aggravates the toxic and side effects of chemotherapy, hinders the treatment plan, weakens the responsiveness of chemotherapy, reduces the quality of life, increases complications and mortality, and seriously endangers the physical and mental health of patients with lung cancer. The causes and pathogenesis of tumor cachexia are extremely complex, which makes its treatment difficult and complex. Controlling cachexia in lung cancer patients requires many means such as anti-tumor therapy, inhibition of inflammatory response, nutritional support, physical exercise, and relief of symptoms to exert the synergistic effect of multimodal therapy against multiple mechanisms of tumor cachexia. To date, there has been a consensus within the discipline that no single therapy can control the development of cachexia. Some therapies have made some progress, but they need to be implemented in combination with multimodal therapy after fully assessing the individual characteristics of lung cancer patients. This article reviews the application of drug therapy and nutritional support in lung cancer patients, and looks forward to the research direction of cachexia control in lung cancer patients.

ABSTRACT

ObjectiveTo explore the mechanism of Liu Junzitang in preventing and treating muscle atrophy in mice with lung cancer cachexia based on the signal transducer and activator of transcription 3(STAT3)/ubiquitin proteasome pathway in vivo. MethodForty C57BL/6 mice aged six weeks were randomly divided into a blank group, a model group, a Liu Junzitang group, an inhibitor group (stattic group),and a Liu Junzitang + inhibitor group (combination group), with eight mice in each group. The cachectic muscle atrophy model was induced by subcutaneous inoculation of Lewis lung cancer cell line under the right anterior armpit in mice except those in the blank group. On the 8th day after subcutaneous inoculation, the mice in the corresponding groups received Liu Junzitang (9.56 g·kg-1·d-1) by gavage and intraperitoneal injection of stattic [25 mg·kg-1·(2 d)-1]. After three weeks of drug intervention, the body weight and gastrocnemius muscle weight were recorded. Hematoxylin-eosin (HE) staining was used to observe the pathological changes and cross-sectional area of gastrocnemius muscle fibers in mice. Western blot was used to detect the expression of phosphorylated-STAT3 (p-STAT3), STAT3, muscle atrophy F-box (MAFbx), and muscle RING finger protein 1 (MuRF1) in the gastrocnemius muscle. Real-time fluorescence quantitative polymerase chain reaction (Real-time PCR) was used to detect the mRNA expression of STAT3, MAFbx, and MuRF1 in the gastrocnemius muscle. ResultCompared with the blank group, the model group showed lightened body and the gastrocnemius muscle, reduced cross-sectional area of gastrocnemius muscle fibers, and increased protein expression of p-STAT3, STAT3, MAFbx, and MuRF1 and mRNA expression of STAT3, MuRF1, and MAFbx in the gastrocnemius muscle (P<0.05). Compared with the model group, the Liu Junzitang group showed increased body weight, gastrocnemius muscle weight, and cross-sectional area of gastrocnemius muscle fibers (P<0.05), and decreased protein expression of p-STAT3, STAT3, MuRF1, MAFbx, and mRNA expression of STAT3 and MAFbx in gastrocnemius muscle (P<0.05). Compared with the model group, the inhibitor group showed increased body weight and cross-sectional area of gastrocnemius muscle fibers (P<0.05), and reduced protein expression of p-STAT3, STAT3, MuRF1, MAFbx, and mRNA expression of STAT3 and MAFbx in gastrocnemius muscle (P<0.05). Compared with the model group, the combination group showed increased body weight and gastrocnemius muscle weight (P<0.05),and decreased protein expression of p-STAT3, STAT3, MuRF1, and mRNA expression of STAT3 and MAFbx in the gastrocnemius muscle (P<0.05). Compared with the Liu Junzitang group, the stattic group and the combination group showed reduced expression of p-STAT3 protein in the gastrocnemius muscle (P<0.05). ConclusionLiu Junzitang can prevent and treat muscle atrophy in mice with lung cancer cachexia, and its mechanism may be associated with the protein and mRNA expression related to the STAT3-mediated ubiquitin proteasome pathway.

ABSTRACT

Abstract Background: Rheumatoid arthritis (RA) generates an inflammatory profile that predisposes to total and visceral fatty accumulation and reduced fat free mass (FFM). This metabolic disorder contributes to poor functionality, increased cardiovascular risk and higher mortality. This study aimed to address a systematic review with meta-analysis to determine the effect of biological and targeted synthetic disease-modifying antirheumatic drugs (bDMARDs and tsDMARDs) on body composition (BC) of patients with RA. Methods: The search was conducted at the electronic databases PubMed, Cochrane Library, Embase, Lilacs and grey literature. This investigation was carried until July 2021. Outcomes of interest were total weight, body mass index (BMI), fat mass (FM) and FFM. A meta-analysis comparing these outcomes in RA patients under bDMARD treatment versus controls was performed. Results: Out of 137 studies reviewed, 18 were selected: fifteen prospective cohorts, two retrospective cohorts, and one cross-sectional study. The studies comprised 1221 patients, 778 on bDMARD treatment and 443 controls, which included RA patients under conventional synthetic DMARD (csDMARD). No study addressing BC analysis in patients using tsDMARD was found. The mean age and duration of the disease was 56.7 years and 6.77 years, respectively. Ten studies demonstrated a significant increase of total weight in 88.2% of patients and 42.3% for BMI. In studies that analyzed BC by double X-ray absorptiometry (DXA), the increase in total weight and BMI correlated positively to the increase in FFM. The meta-analysis carried out in five studies showed no significant difference of the mean difference for total weight 0.12 kg (95% CI − 5.58, 5.82), BMI 0.08 kg/m2 (95% CI − 1.76, 1.92), FM − 0.08 kg (95% IC − 5.31, 5.14), and FFM − 2.08 kg (95% CI − 7.37, 3.21). Conclusion: This systematic review suggests a possible impact of bDMARDs on BC of RA patients, even though, the meta-analysis carried out in a small part of these studies was not able to confirm significant variation in BC components. Trial registration: PROSPERO code: CRD42020206949.

ABSTRACT

Growth differentiation factor 15(GDF15) is a member of transforming growth factor β superfamily. Animal studies find that GDF15, bounding with centrally expressed receptors, reduces body weight by inhibiting food intake and by enhancing energy metabolism. In addition, GDF15 is also involved in the effects of tumor cachexia and platinum-based chemotherapy on body weight. GDF15 and its receptor could be potential targets for the treatment of such diseases.

ABSTRACT

Resumen: Introducción: La caquexia es un síndrome asociado al cáncer avanzado, VIH, pacientes en quimioterapia y quienes tienen seguimiento en cuidados paliativos. La prevalencia es de 25% de los pacientes con diagnóstico de cáncer, 26% en quienes reciben quimioterapia y de 14 a 38% de pacientes con VIH. Un pilar para el manejo es el cannabis debido al efecto del delta-9-tetrahidrocanabinol (THC), del cual se derivó el dronabinol, un fármaco desarrollado para estimular apetito y ganancia de peso. El objetivo de esta revisión bibliográfica es obtener la información sobre los cannabinoides y la evidencia más sólida existente con respecto al uso del dronabinol en pacientes que han presentado pérdida de peso y apetito. Material y métodos: Revisión de la bibliografía con buscador PubMed con las palabras clave Palliative care (cuidados paliativos), Cannabinoids (cannabinoides), cachexia (caquexia), Dronabinol (dronabinol), Appetite (apetito), de 1990 a 2018, limitado a humanos, obteniendo 259 artículos, eliminando 222 por repetirse o tener poca relevancia, dejando 37 artículos para análisis. Resultados: De 37 artículos revisados, nueve fueron estudios experimentales, 10 revisiones sistematizadas, un metaanálisis y 16 artículos de recomendaciones y sugerencias de manejo. Conclusión: El manejo del apetito y pérdida de peso en pacientes en cuidados paliativos, VIH, ancianos o en quimioterapia debe ser multidisciplinario, involucrando nutriólogos, psicólogos y médicos, ajustando el manejo a las características individuales que manifiesten. El dronabinol es un fármaco de primera elección para el manejo de dichos síntomas cuando la historia natural de la enfermedad se acompaña de náusea, vómito o dolor.


Abstract: Introduction: Cachexia is a syndrome associated with advanced cancer, HIV, patients on chemotherapy and those who are followed in palliative care. The prevalence is 25% of patients diagnosed with cancer, 26% in those receiving chemotherapy and 14 to 38% of patients with HIV. A mainstay for management is cannabis, due to the effect of delta-9-tetrahydrocannabinol (THC) from which dronabinol, a drug developed to stimulate appetite and weight gain, was derived. The aim of this literature review is to obtain information on cannabinoids and the strongest existing evidence regarding the use of dronabinol in patients who have presented weight and appetite loss. Material and methods: Literature review with PubMed search engine with the keywords Palliative care, Cannabinoids, cachexia, Dronabinol, Appetite, from 1990 to 2018, limited to humans, obtaining 259 articles, eliminating 222 for repetition or low relevance, leaving 37 articles for analysis. Results: Out of 37 articles reviewed 9 were experimental studies, 10 systematized reviews, 1 meta-analysis and 16 articles of recommendations and management suggestions. Conclusion: The management of appetite and weight loss in palliative care, HIV, elderly or chemotherapy patients should be multidisciplinary, involving nutritionists, psychologists and physicians, adjusting the management to the individual characteristics manifested. Dronabinol is a drug of first choice for the management of these symptoms when the natural history of the disease is accompanied by nausea, vomiting or pain.

ABSTRACT

Resumen La insuficiencia cardiaca (IC) representa uno de los problemas mundiales de salud pública más importantes, ya que existe un aumento en su prevalencia y se estima que 23 millones de la población mundial viven con este problema. Esta entidad se define por la presencia de anormalidades estructurales y funcionales del músculo cardiaco que conducen a un deterioro en la capacidad del llenado y eyección ventricular. Múltiples comorbilidades se han asociado a un incremento en el riesgo de desarrollo de enfermedades cardiovasculares. La hipertensión se ha reconocido como uno de los factores más importantes, sin embargo, la obesidad, el síndrome metabólico, así como la diabetes, también juegan un papel importante en la aparición de dicha enfermedad. Es frecuente encontrar en pacientes hospitalizados con IC deterioro en el estado nutricional caracterizado principalmente por la presencia de deficiencias nutricionales y sarcopenia, que, en ocasiones, puede progresar y manifestarse como caquexia. Por lo anterior, una evaluación adecuada mediante el uso correcto de herramientas para detección de riesgo nutricional es imperativa, se hace necesaria para prevenir los riesgos que esto implica. Existen múltiples parámetros antropométricos y bioquímicos para definir el estado nutricional de los pacientes hospitalizados, sin embargo, las alteraciones en el volumen sanguíneo presentes en pacientes con IC pueden alterar el resultado de dicha evaluación. Las modificaciones dietéticas en la prevención y tratamiento de diversas enfermedades cardiovasculares mediante un buen apego a patrones de alimentación tales como la dieta DASH (enfoques dietéticos para detener la hipertensión, por sus siglas en inglés) y la dieta mediterránea se han asociado inversamente con la incidencia de IC.


Abstract Heart failure (HF) is one of the most important global public health problems, as there is an increase in its prevalence and an estimated 23 million of the world's population live with this problem. HF is defined by the presence of structural and functional abnormalities of the cardiac muscle leading to an impairment of ventricular filling and ejection. Multiple comorbidities have been associated with an increased risk of developing cardiovascular diseases. Hypertension has been recognized as one of the most important factors, however, obesity, metabolic syndrome, as well as diabetes also play an important role in the onset of the disease. It is common to find in decompensated heart failure hospitalized patients an impaired nutritional status characterized mainly by the presence of nutritional deficiencies and sarcopenia, which can sometimes progress to cachexia. Therefore, an adequate evaluation through the correct use of nutritional risk tools should be the cornerstone to the prevention of risks. Multiple anthropometric and biochemical parameters are available to establish the nutritional status of hospitalized patients, however, alterations in blood volume presented in patients with HF may alter the result of such assessment. The effectiveness of dietary modifications in the prevention and treatment of different cardiovascular diseases enhanced by appropriate adherence to eating patterns such as the DASH and Mediterranean diet have been inversely associated with the incidence of HF.

ABSTRACT

OBJETIVO: O objetivo desse estudo foi verificar o efeito do treinamento resistido na sobrevida de camundongos C57BL/6 com caquexia associada ao melanoma cutâneo. MATERIAL E MÉTODOS: A amostra foi constituída por 64 (camundongos C57BL/6 fêmeas, com idade entre 10 e 12 semanas, com cerca de 50 ± 5 gramas de peso corporal. Os camundongos foram distribuídos aleatoriamente em quatros grupos: i. camundongos controle, com indução de tumor, inativos fisicamente (Controle, n = 16); ii. camundongos submetidos ao treinamento resistido diário somente antes da indução tumoral (Treino 1, n = 16); iii. camundongos submetidos ao treinamento resistido diário antes e após da indução tumoral (Treino 2, n = 16); iv. camundongos submetidos ao treinamento resistido diário após a indução tumoral e apresentado quadro caquético (Treino 3, n = 16). No procedimento para treinamento resistido (TR) com choque, foi utilizada uma escada com 110 cm de altura, 18 cm de largura, 2 cm entre os degraus e 80 graus de inclinação. No procedimento para TR com choque, foi utilizada uma escada 110 cm de altura, 18 cm de largura, 2 cm entre os degraus e 80 graus de inclinação. O exercício resistido baseia-se na subida dos camundongos. Na plataforma de saída, aplicava-se um choque elétrico como estímulo para subir as escadas, nesta etapa era aplicada o choque nas quatro patas do animal com uma tensão elétrica de 20 volts a uma frequência de 45 Hertz durante seis séries de oito repetições, cada uma com noventa segundos de intervalo entre as séries. Os grupos de camundongos foram submetidos a acompanhamento por no máximo 15 dias após o diagnóstico da caquexia a fim de comparar a sobrevida geral relacionada ao câncer entre os grupos de estudo. As curvas de sobrevivência de KaplanMeier foram estimadas para cada evento e as curvas dos diferentes grupos foram comparadas usando o teste de Log-rank. O tempo de sobrevida proposta foi de 25 dias após inoculação. RESULTADOS: Os resultados apresentados nesse estudo mostraram que não houve diferença significativa (p <0,05) entre as propostas de treino. CONCLUSÃO: Não houve diferença na sobrevida de animais com caquexia associada ao modelo tumoral singênico de melanoma cutâneo com intervenção de exercício resistido ou sedentários.


OBJECTIVE: The objective of this study was to verify the effect of resistance training on the survival of C57BL / 6 mice with cachexia associated with cutaneous melanoma. MATERIAL AND METHODS: The sample consisted of 64 (female C57BL/6 mice, aged between 10 and 12 weeks, with approximately 50 ± 5 grams of body weight. The mice were randomly distributed into four groups: i. control mice, with tumor induction, physically inactive (Control, n = 16); ii. mice submitted to daily resistance training only before tumor induction (Training 1, n = 16); iii. Mice submitted to daily resistance training before and after tumor induction (Training 2, n = 16); iv. Mice submitted to daily resistance training after tumor induction and presented a cachectic condition (Training 3, n = 16). In the resistance training procedure (RT) with shock, a 110 cm high, 18 cm wide, 2 cm between the steps, and 80 degrees inclination ladder was used. In the procedure for shock resistance training (TR), a ladder 110 cm high, 18 cm wide, 2 cm between the rungs, and 80 degrees of inclination was used. The resisted exercise is based on the climbing of the mice. On the exit platform, an electric shock was applied as a stimulus to climb the stairs. In this step, the shock was applied to the four legs of the animal with an electric voltage of 20 volts at a frequency of 45 Hertz during six series of eight repetitions, each with ninety-seconds intervals between the series. The mice groups underwent follow-up for no more than 15 days after diagnosis of cachexia to compare overall cancer-related survival between the study groups. Kaplan-Meier survival curves were estimated for each event, and the curves of the different groups were compared using the Log-rank test. The proposed survival time was 25 days after inoculation. RESULTS: The results presented in this study showed no significant difference (p <0.05) between the training proposals. CONCLUSION: There was no difference in animals' survival with cachexia associated with the syngeneic melanoma skin tumor model with either resistance exercise or sedentary intervention.

ABSTRACT

Las enfermedades crónicas degenerativas han ganado gran interés e importancia en el ámbito de la salud debido a la alta carga mundial de morbilidad y la gran tasa de discapacidad que las mismas generan. A su vez, la prevalencia de desnutrición afecta un 40-60% de los pacientes hospitalizados, lo que supone un aumento de los costos sanitarios, mayor morbimortalidad y aumento de las tasas de discapacidad. Diversos conceptos surgen en la literatura relacionando la pérdida de masa muscular, la enfermedad y la desnutrición. El objetivo del presente artículo es definir los conceptos de desnutrición, fragilidad, caquexia y sarcopenia. Se buscó describir su prevalencia, diferenciar los mecanismos que generan cada situación y su impacto en la composición corporal(AU)


Abstract Chronic degenerative diseases have won great interest and value in the field of health due to the high global burden of morbidity and the high rate of disability that they generate. At the same time, the prevalence of malnutrition affects 40-60% of hospitalized patients, which implies an increase in health costs, greater morbi mortality and an increase in disability rates. Various concepts emerge in the literature in which the loss of muscle mass, disease and malnutrition are related. The objective of this article is to define the concepts of malnutrition, frailty, cachexia and sarcopenia. The aim was to describe its prevalence, to differentiate the mechanisms that generate each situation and its impact on body composition(AU)

ABSTRACT

Food and eating are of great significance to humans, as we are the only creatures that establish relationships and sustain a social network through food and eating. Recent studies revealed that patients with advanced cancer and their family members often experience complicated eating-related distress due to tumors themselves, side effects of cancer treatments, and negative impacts of cancer cachexia. Therefore, we suggested the importance of the integration of palliative, supportive, and nutritional care to alleviate eating-related distress among patients and family members, and the significance of the development of tools to measure their distress in supportive and palliative care settings. No care strategies for eating-related distress experienced by patients and family members have been established, and the development of an interdisciplinary psychosocial approach and integrative care is required. As such, we are planning to start a nutritional support and cancer cachexia clinic in the National Cancer Center, and disseminate a newly developed care program across Japan.
