ABSTRACT

Cancer-related anorexia-cachexia syndrome (CACS) is a debilitating condition afflicting up to 80% of advanced-stage cancer patients. Characterized by progressive weight loss, muscle wasting, and metabolic abnormalities, CACS significantly compromises patients' quality of life and treatment outcomes. This comprehensive review navigates through its intricate physiopathology, elucidating its stages and diagnostic methodologies. CACS manifests in three distinct stages: pre-cachexia, established cachexia, and refractory cachexia. Early detection is pivotal for effective intervention and is facilitated by screening tools, complemented by nutritional assessments and professional evaluations. The diagnostic process unravels the complex interplay of metabolic dysregulation and tumor-induced factors contributing to CACS. Management strategies, tailored to individual patient profiles, encompass a spectrum of nutritional interventions. These include dietary counseling, oral nutritional supplements, and, when necessary, enteral nutrition and a judicious use of parenteral nutrition. Specific recommendations for caloric intake, protein requirements, and essential nutrients address the unique challenges posed by CACS. While pharmacological agents like megestrol acetate may be considered, their use requires careful evaluation of potential risks. At its core, this review underscores the imperative for a holistic and personalized approach to managing CACS, integrating nutritional interventions and pharmacological strategies based on a nuanced understanding of patient's condition.

ABSTRACT

Importance: Currently there is no standard therapy to improve cancer-related anorexia, hampering survival. Mirtazapine has been suggested as a feasible option in this context. Objectives: To assess the effect of mirtazapine on appetite and energy consumption in patients with advanced non-small cell lung cancer (NSCLC). Design, Setting, and Participants: This randomized, double-blind, placebo-controlled clinical trial including adults was performed in a tertiary cancer care center from August 2018 to May 2022 with a follow-up of 8 weeks. Overall, 134 patients were screened; 114 were assessed for eligibility and 28 were excluded. Interventions: Patients were randomized in a 1:1 ratio to receive mirtazapine, 15 mg, or placebo for 2 weeks followed by a dose escalation to 30 mg until week 8 or placebo. Both groups received nutritional assessment and dietary advice. Main outcomes and measures: Appetite was assessed by the Anorexia Cachexia Scale and energy intake. Dietary parameters were evaluated at baseline, 4 weeks, and 8 weeks, with a 24-hour dietary recall, and energy quantification based on the Mexican system of nutritional equivalents. Results: A total of 86 patients met the inclusion criteria and were randomized to the placebo (n = 43) or the mirtazapine group (n = 43). The mean (SD) age was 63.5 (11.2) years, 41 were women (57.7%) and had adenocarcinoma, Eastern Cooperative Oncology Group performance status scale score of 1, stage IV NSCLC, and were receiving first-line treatment. Baseline characteristics were similar between groups. There was no difference in appetite scores in patients who received mirtazapine or placebo after 4 and 8 weeks. After 4 weeks, mirtazapine significantly increased energy intake (379.3 kcal; 95% CI, 1382.6-576.1; P < .001) including proteins (22.5 g; 95% CI, 11.5-33.4; P = .001), carbohydrates (43.4 g; 95% CI, 13.1-73.8; P = .006), and fats (13.2 g; 95% CI, 6.0-20.4; P = .006). Fats intake was significantly higher in patients in the mirtazapine group (14.5 g vs 0.7 g; P = .02) after 8 weeks. The mirtazapine group significantly decreased the proportion of patients with sarcopenia (82.8% vs 57.1%, P = .03) at 8 weeks. Patients on mirtazapine tolerated the treatment well, but reported a higher perception of nightmares at 2 weeks based on a 10 cm VAS score (0 [25th-75th percentile, 0-1] vs 0 [25th-75th percentile, 0-0] in the control group; P = .009) but this finding was nonsignificant after 4 and 8 weeks. Conclusion and Relevance: In this randomized clinical trial of patients with advanced NSCLC, there was no difference in appetite scores in all patients who received mirtazapine or placebo, but the mirtazapine group had a significant increase in energy intake through the 4- and 8-week follow-up, mainly in fat intake, which is a better and crucial source of energy. The addition of mirtazapine in the treatment of patients with advanced NSCLC and anorexia may help these patients achieve their energy requirements and improve health-related quality of life, specifically emotional and cognitive functioning.

ABSTRACT

INTRODUCTION: Cancer patients often suffer from malnutrition and early detection and raising awareness of nutritional issues is crucial in this population. METHODS: The Spanish Oncology Society (SEOM) conducted the Quasar_SEOM study to investigate the current impact of the Anorexia-Cachexia Syndrome (ACS). The study employed questionnaires and the Delphi method to gather input from both cancer patients and oncologists on key issues related to early detection and treatment of ACS. A total of 134 patients and 34 medical oncologists were surveyed about their experiences with ACS. The Delphi methodology was used to evaluate oncologists' perspectives of ACS management, ultimately leading to a consensus on the most critical issues. RESULTS: Despite widespread acknowledgement of malnutrition in cancer as a significant issue by 94% of oncologists, the study revealed deficiencies in knowledge and protocol implementation. A mere 65% of physicians reported being trained to identify and treat these patients, with 53% failing to address ACS in a timely manner, 30% not monitoring weight, and 59% not adhering to any clinical guidelines. The lack of experience was identified as the primary hindrance to the use of orexigens in 18% of cases. Furthermore, patients reported concerns and a perception of inadequate attention to malnutrition-related issues from their physicians. CONCLUSION: The results of this study point to a gap in the care of this syndrome and a need to improve education and follow-up of cancer patients with anorexia-cachexia.

ABSTRACT

BACKGROUND: Gastrointestinal and sensory manifestations (GSMs) of coronavirus disease 2019 (COVID-19) may affect food intake, resulting in malnutrition and poor outcomes. We characterized the impact of GSMs and oral nutrition supplementation on energy-protein intake (EPI) and hospital discharge in adult patients with COVID-19. METHODS: Patients from two hospitals were enrolled (n = 357). We recorded the presence and type of GSM at admission, estimated energy requirements (EER) and the EPI based on regular food intake (plate diagram sheets) during hospital stays. Patients not achieving 60% of their EER from food over 2 consecutive days received oral nutrition supplementation (ONS) with a high-energy-protein oral drink. RESULTS: Most patients (63.6%) presented with GSMs at admission. Anorexia was the most common manifestation (44%). Patients with anorexia or more than one GSMs were more likely to not achieve 60% EER on the first day of follow-up and to require the ONS intervention (P ≤ 0.050). Prevalence of at least one GSM was higher in patients who did not achieve hospital discharge than in patients who achieved it (74.2% vs 54.6%, P = 0.038). The patients requiring ONS (26.9%) demonstrated good adherence to the intervention (79.3%), achieved their EER during 95.7% of the supplementation time, and presented with hospital discharge rates similar to patients not requiring ONS (92.2% vs 91.9%, respectively; P = 1.000). CONCLUSIONS: GSM were prevalent in COVID-19 and it impaired EER attendance and patient recovery. ONS was well-tolerated, aided EER attendance, and potentially facilitated hospital discharge.

ABSTRACT

The incidence of neoplastic diseases has increased worldwide, with an estimated global burden of 19.3 million incident cases and 10 million deaths in 2020-a considerable increase compared with 9.6 million deaths in 2018. One of the most prevalent problems faced by patients with cancer and their physicians is malnutrition. It is estimated that patients with cancer have important nutritional alterations in 25% to 70% of cases, which directly affects many spheres of patient care and well-being, including quality of life, treatment toxicity, and survival outcomes. Despite the overwhelming need to address this pressing issue, current evidence in terms of pharmacologic interventions for cancer-related anorexia remains inconclusive, and there is no current standard of care for patients with cancer-related anorexia. Nonetheless, international guidelines recommend promoting anabolism through nutritional, physical, and pharmacologic therapies. In this review, the available information is summarized regarding pharmacologic therapies to treat cancer-related anorexia and findings are highlighted from a clinical stance.

ABSTRACT

INTRODUCTION: Cancer cachexia is a complex multifaceted syndrome involving functional impairment, changes in body composition, and nutritional disorders. The treatment of cancer cachexia can be based on these three domains of the syndrome. Phase II and III trials of anamorelin, a ghrelin mimetic agent, have been shown to increase body weight in patients with cancer cachexia, mainly by increasing muscle and fat mass. Anamorelin has been shown to improve anorexia scores. AREAS COVERED: This review aims to outline the effect of anamorelin on body composition and functional parameters as well as to discuss the clinical importance of these alterations in patients with cancer cachexia. EXPERT OPINION: To date, there is no treatment approved to enhance body composition and functional parameters in patients with cancer cachexia. Anamorelin, the most advanced therapy to treat cachexia, has not yielded convincing results in all aspects of the syndrome. In particular, no effect has been noted on physical function and long-term survival. Along with these essential improvements for future interventions with anamorelin, subsequent studies must address other etiologies of cancer, rather than non-small cell lung cancer, and add complementary therapies, such as exercise training and nutritional interventions, in an attempt to overcome cancer cachexia.

ABSTRACT

The objective of this study is to assess the effect of alcohol consumption, anxiety, and food restriction before and after consuming alcohol and body image on the risk of anorexia and bulimia in college students from Tijuana, Baja California, through predictive statistical models. A quantitative, descriptive, and cross-sectional design and a non-probabilistic sample of 526 college students from Tijuana, Baja California, México were used. Application of the scales (with acceptable psychometric properties) was conducted in classrooms. Through path analyses, four models were found with adequate indicators of goodness of fit: (1) risk of anorexia in women [Chi Square (X2) = 5.34, p = 0.376, Adjusted Determination Coefficient (R2)= 0.250]; (2) anorexia risk for men (X2 = 13.067, p = 0.192, R2 = 0.058); (3) risk of bulimia in women (X2 = 3.358, p = 0.645, R2 = 0.202); and bulimia risk for men (X2 = 14.256, p = 0.075, R2 = 0.284). The findings provide empirical evidence for the food and alcohol disturbance model.

ABSTRACT

OBJECTIVE: To evaluate the prevalence of anorexia and weight loss at diagnosis (pre-treatment), to identify the factors associated with pre-treatment weight loss, and to determine the prognostic role of anorexia and weight loss in the overall survival of patients with stage IV lung cancer. METHODS: This was a retrospective observational cohort study. The patients were stratified by the presence/absence of anorexia and of pre-treatment weight loss, which generated a measure composed of four categories, which were the independent variables. RESULTS: Among the 552 patients included in the study, anorexia and pre-treatment weight loss were present in 39.1% and 70.1%, respectively. After adjusting for age, male gender, and Karnofsky performance status, we found that anorexia and tumor size were significantly associated with pre-treatment weight loss. In a Cox multivariate analysis, adjusted for age, male gender and low Karnofsky performance status were found to be independent predictors of worse survival, as was concomitance of anorexia and weight loss. CONCLUSIONS: Anorexia and pre-treatment weight loss appear to be relevant problems in the follow-up of patients with advanced (stage IV) lung cancer Specific interventions are of crucial importance in individualized treatment plans, even within the context of palliative care.

RESUMO Objetivo: Avaliar a prevalência de anorexia e perda de peso ao diagnóstico (pré-tratamento), os fatores associados à perda de peso pré-tratamento e o papel prognóstico da anorexia e da perda de peso na sobrevida global de pacientes com câncer de pulmão em estádio IV. Métodos: Estudo de coorte retrospectivo observacional. Os pacientes foram estratificados, dependendo da presença/ausência de anorexia e da presença/ausência de perda de peso pré-tratamento, o que gerou uma medida composta de anorexia e perda de peso de quatro níveis, que foi a variável independente. Resultados: Entre os 552 pacientes incluídos no estudo, as prevalências de anorexia e de perda de peso pré-tratamento foram de 39,1% e 70,1%, respectivamente. Após ajustar para idade, sexo masculino e índice de Karnofsky, a presença de anorexia e o tamanho do tumor foram significativamente associados à perda de peso pré-tratamento. Na análise multivariada de Cox, após ajustar para a idade, as variáveis sexo masculino, presença concomitante de anorexia e perda de peso e índice de Karnofsky reduzido foram preditores independentes de pior probabilidade de sobrevida. Conclusões: O presente estudo demonstrou que a presença de anorexia e de perda de peso pré-tratamento são problemas relevantes no seguimento de pacientes com câncer de pulmão avançado (estádio IV). Intervenções específicas são de crucial importância no plano de assistência individualizada, mesmo dentro da proposta de cuidados paliativos.

ABSTRACT

The population of older adults is growing globally. This increase has led to an accumulation of chronic illnesses, so-called age-related diseases. Diet and nutrition are considered the main drivers of the global burden of diseases, and this situation applies especially to this population segment. It relates directly to the development of coronary heart disease, hypertension, some types of cancer, and type 2 diabetes, among other diseases, while age-associated changes in body composition (bone and muscle mass, fat, sarcopenia) constitute risk factors for functional limitations affecting health status and the quality of life. Older adults present eating and swallowing problems, dry mouth, taste loss, and anorexia among other problems causing "anorexia of aging" that affects their nutritional status. The strategies to overcome these situations are described in this study. The impact of oral food processing on nutrition is discussed, as well as approaches to improve food acceptance through the design of innovative foods. These foods should supply a growing demand as this group represents an increasing segment of the consumer market globally, whose needs must be fulfilled.

ABSTRACT

In cancer patients treated with radiotherapy to the abdominopelvic region, dietary modifications and the use of functional foods (fortified food with added ingredients to provide specific health improving benefits, such as antioxidants, omega-3 fatty acids, and glutamine), may contribute to the improvement of the toxic effects of treatment, including nausea, diarrhea, and constipation, among others. With the aim of analyzing which coadjuvant foods benefit these patients, scientific evidence was gathered by a group of experts. For these patients, the authors recommend a diet that includes sufficient foods rich in antioxidants and polyphenols instead of supplements. Docosahexaenoic and eicosapentaenoic acids have proven useful for the management of anorexia/cachexia in pancreatic cancer patients. Probiotics composed of Lactobacillus spp. and Bifidobacterium spp. are regarded as safe even in patients with neutropenia and have been proven to decrease gastrointestinal symptoms. Several factors should be considered before probiotic supplementation, these include the stage of the disease, radiation dose, and symptomatology of each patient. There is no demonstrated clear benefit to the use of glutamine, so it is not recommended due to its high cost.

ABSTRACT

INTRODUCTION: Cachexia and anorexia are among the most frequent symptoms in patients with cancer. Cannabinoids have been used in patients with advanced cancer; however, their role is still controversial. METHODS: To answer this question we used Epistemonikos, the largest database of systematic reviews in health, which is maintained by screening multiple information sources, including MEDLINE, EMBASE, Cochrane, among others. We extracted data from the systematic reviews, reanalyzed data of primary studies, and generated a summary of findings table using the GRADE approach. RESULTS AND CONCLUSIONS: We identified ten systematic reviews including three studies overall, of which two were randomized trials. We concluded it is not clear whether cannabinoids have any positive effect on increasing weight because the certainty of the evidence is very low. They might not have any effect on appetite, and are probably associated to frequent adverse effects.


INTRODUCCIÓN: La caquexia y la anorexia se encuentran dentro de los síntomas más frecuentes en los pacientes oncológicos. Los cannabinoides han sido propuestos para su manejo en los pacientes con cáncer avanzado, sin embargo, su rol es controvertido. MÉTODOS: Para responder esta pregunta utilizamos Epistemonikos, la mayor base de datos de revisiones sistemáticas en salud a nivel mundial, la cual es mantenida mediante búsquedas en múltiples fuentes de información, incluyendo MEDLINE, EMBASE, Cochrane, entre otras. Extrajimos los datos desde las revisiones identificadas, reanalizamos los datos de los estudios primarios y preparamos una tabla de resumen de los resultados utilizando el método GRADE. RESULTADOS Y CONCLUSIONES: Identificamos diez revisiones sistemáticas, que en conjunto incluyen tres estudios, entre ellos dos ensayos aleatorizados. Concluimos que no está claro si los cannabinoides logran o no un aumento de peso en pacientes con anorexia-caquexia porque la certeza de la evidencia es muy baja, podrían no tener tampoco efecto sobre el apetito, y probablemente se asocian a efectos adversos frecuentes.

ABSTRACT

Negative energy balance promotes physiological adaptations that ensure the survival of animals. The hypothalamic-pituitary-thyroid axis regulates basal energy expenditure and its down-regulating adaptation to negative energy balance is well described: in fasting, the serum content of thyrotrophin (TSH) and thyroid hormones (TH) decreases, enhancing the survival odds of individuals. By contrast, dehydration-induced anorexic (DIA) rats present an impaired hypothalamic-pituitary-thyroid (HPT) axis adaptation despite their negative energy balance: increased circulating TSH levels. The implication of cocaine- and amphetamine-regulated transcript (CART), an anorexic peptide, in HPT axis function impairment and food-avoidance behaviour displayed by DIA animals is unknown. Because CART is co-expressed with the peptide that regulates the HPT axis in hypophysiotrophic paraventricular nucleus (PVN) neurones (TSH-releasing hormone), we analysed CART expression and possible implications with respect to high TSH levels of DIA animals. We examined whether changes in CART expression from the lateral hypothalamic area (LHA) and arcuate nucleus (ARC) could participate in food-avoidance of DIA rats. DIA and forced-food restricted (FFR) animals reduced their body weight and food intake. FFR rats had a down-regulation of their HPT axis (reduced serum TH and TSH content), whereas DIA animals had reduced TH but increased TSH levels. CART mRNA expression in the ARC decreased similarly between experimental groups and diminished in anterior, medial PVN and in LHA of FFR animals, whereas DIA animals showed unchanged levels. This impaired CART mRNA expression in the anterior PVN and LHA could be related to the aberrant feeding behaviour of DIA rats but not to their deregulated HPT axis function.

ABSTRACT

PURPOSE OF REVIEW: Cancer anorexia is a negative prognostic factor and is broadly defined as the loss of the interest in food. However, multiple clinical domains contribute to the phenotype of cancer anorexia. The characterization of the clinical and molecular pathophysiology of cancer anorexia may enhance the efficacy of preventive and therapeutic strategies. RECENT FINDINGS: Clinical trials showed that cancer anorexia should be considered as an umbrella encompassing different signs and symptoms contributing to appetite disruption in cancer patients. Loss of appetite, early satiety, changes in taste and smell are determinants of cancer anorexia, whose presence should be assessed in cancer patients. Interestingly, neuronal correlates of cancer anorexia-related symptoms have been revealed by brain imaging techniques. SUMMARY: The pathophysiology of cancer anorexia is complex and involves different domains influencing eating behavior. Limiting the assessment of cancer anorexia to questions investigating changes in appetite may impede correct identification of the targets to address.

ABSTRACT

PURPOSE:: To assess antioxidant effects of açaí seed extract on anorexia-cachexia induced by Walker-256 tumor. METHODS:: A population of 20 lab rats were distributed into four groups (n=5): Control Group (CG), which only received tumor inoculation. Experimental Group-100 (EG-100), with animals submitted to tumor inoculation and treated with seed extract in a 100 mg / ml concentration through gavage. Experimental Group-200 (EG-200), with animals submitted to tumor inoculation and treated with seed extract in a 200 mg / ml concentration. Placebo Group (GP), which received tumor inoculation and ethanol-water solution. We analyzed proteolysis, lipid peroxidation, tumor diameter and weight. RESULTS:: Lipid peroxidation was representative only in the cerebral cortex, where there was more oxidative stress in rats treated with the extract (p = 0.0276). For proteolysis, there was less muscle damage in untreated rats (p = 0.0312). Only tumor diameter in treated rats was significantly lower (p = 0.0200) compared to untreated ones. CONCLUSIONS:: The açaí seed extract showed no beneficial effect on the general framework of the cachectic syndrome in lab rats. However, some anticarcinogenic effects were observed in the tumor diameter and weight.

The chikungunya virus (CHIKV) epidemic in the Americas is of significant public health importance due to the lack of effective control and prevention strategies, severe disease morbidity among susceptible populations, and potential for persistent arthralgia and long-term impaired physical functionality. Using surveillance data of suspected CHIKV cases, we describe the first reported outbreak in the U.S. Virgin Islands. CHIKV incidence was highest among individuals aged 55-64 years (13.1 cases per 1,000 population) and lowest among individuals aged 0-14 years (1.8 cases per 1,000 population). Incidence was higher among women compared to men (6.6 and 5.0 cases per 1,000 population, respectively). More than half of reported laboratory-positive cases experienced fever lasting 2-7 days, chills/rigor, myalgia, anorexia, and headache. No clinical symptoms apart from the suspected case definition of fever ≥ 38°C and arthralgia were significantly associated with being a reported laboratory-positive case. These results contribute to our knowledge of demographic risk factors and clinical manifestations of CHIKV disease and may aid in mitigating future CHIKV outbreaks in the Caribbean.
