RESUMO

RESUMEN La paracoccidioidomicosis es una micosis profunda sistémica, endémica en algunos países de Latinoamérica, de presentación clínica es de evolución aguda/subaguda, en nuestro país es el principal diagnóstico diferencial de la tuberculosis pulmonar. Se describe el caso clínico de un hombre de 48 años, procedente de zona rural, inmunocompetente, que se presentó clínicamente por dificultad respiratoria, pérdida de peso de forma progresiva y lesiones en mucosas oral; como hallazgos radiológicos presentó infiltrados reticulares bilaterales. Desde el punto de vista micológico se evidenció la presencia del microorganismo en diversas muestras biológicas: biopsias de lesiones orofaríngeas y estudio micológico del esputo. Se realizó tratamiento dirigido con antimicótico intravenoso presentando buena respuesta al mismo con mejoría clínica.


ABSTRACT Paracoccidioidomycosis is a deep systemic mycosis, endemic in some Latin American countries, with an acute/subacute clinical presentation. In our country, it is the main differential diagnosis of pulmonary tuberculosis. We describe the clinical case of a 48-year-old man from a rural area, immunocompetent, who presented clinically with respiratory distress, progressive weight loss and lesions in the oral mucosa; as radiological findings, he presented bilateral reticular infiltrates. From a mycological point of view, the presence of the microorganism was evidenced in various biological samples: biopsies of oropharyngeal lesions and mycological study of sputum. Targeted treatment with intravenous antifungals was performed, presenting a good response to it with clinical improvement.

RESUMO

Fortea et al.'s. (2024) recent data analysis elegantly calls attention to familial late-onset Alzheimer's disease (AD) with APOE4 homozygosity. The article by Grant (2024) reviews the factors associated with AD, particularly the APOE genotype and lifestyle, and the broad implications for prevention, both for individuals with the lifestyles associated with living in resource-rich countries and for those enduring environmental adversity in poverty settings, including high exposure to enteric pathogens and precarious access to healthcare. Grant discusses the issue of APOE genotype and its implications for the benefits of lifestyle modifications. This review highlights that bearing APOE4 could constitute an evolutionary benefit in coping with heavy enteric infections and malnutrition early in life in the critical formative first two years of brain development. However, the critical issue may be that this genotype could be a health concern under shifts in lifestyle and unhealthy diets during aging, leading to severe cognitive impairments and increased risk of AD. This commentary supports the discussions of Grant and the benefits of improving lifestyle for decreasing the risks for AD while providing further understanding and modelling of the early life benefits of APOE4 amidst adversity. This attention to the pathophysiology of AD should help further elucidate these critical, newly appreciated pathogenic pathways for developing approaches to the prevention and management in the context of the APOE genetic variations associated with AD.

RESUMO

BACKGROUND: Hospitalized individuals present high rates of malnutrition and loss of muscle mass (MM). Imaging techniques for assessing MM are expensive and scarcely available in hospital practice. The Global Leadership Initiative on Malnutrition (GLIM) proposed a framework for malnutrition diagnosis that includes simple measurements to assess MM, such as calf circumference (CC) and mid-upper arm circumference (MUAC). This study aimed to analyze the validity of the GLIM criteria with CC and MUAC for malnutrition diagnosis, using Subjective Global Assessment (SGA) as the reference standard, in inpatients. METHODS: A prospective cohort study was conducted on 453 inpatient adults in a university hospital. The presence of malnutrition was assessed within 48 h of hospital admission using SGA and GLIM criteria using CC and MUAC as phenotypic criteria for malnutrition diagnosis. Accuracy, agreement tests, and logistic regression analysis adjusted for confounders were performed to test the validity of the GLIM criteria for malnutrition diagnosis. RESULTS: The patients were aged 59 (46-68) years, 51.4% were male, and 67.8% had elective surgery. Compared with SGA, the GLIM criteria using the two MM assessment measures showed good accuracy (area under the curve > 0.80) and substantial agreement (κ > 0.60) for diagnosing malnutrition. The highest sensitivity was obtained with GLIMCC (89%), whereas GLIMMUAC showed high specificity (>90%). Also, malnutrition identified by GLIMCC and GLIMMUAC was significantly associated with prolonged hospitalization and in-hospital death. CONCLUSION: In the absence of imaging techniques to assess MM, the use of CC and MUAC measurements from the GLIM criteria demonstrated satisfactory validity for diagnosing malnutrition in hospitalized patients.

RESUMO

Background: Malnutrition has important short- and long-term consequences in children under age five. Malnutrition encompasses undernutrition, overnutrition, and the coexistence of both of them, known as the double burden of malnutrition (DBM). Objective: The aim of this study was to estimate the prevalence of undernutrition, overnutrition, and the DBM among these children at the national level and by living area in Panama. Methods: Data from the National Health Survey of Panama (ENSPA, Spanish acronym), a population-based, cross-sectional study carried out in 2019 were used. Stunting, wasting, overweight, and obesity were defined according to the cut-off points of the World Health Organization Growth Standards. Undernutrition was defined as being stunted only, wasted only or both; overnutrition was defined as being overweight only or obese only; and the DBM was defined as the co-occurence of stunting and overweight/obesity in the same child. Prevalence and general characteristics at the national level and by living area were weighted. Findings: The prevalence of undernutrition was 15.3% (95% confidence interval (CI) 13.4-17.3) at the national level and 36.6% (CI: 30.1-43.5) in indigenous areas. The prevalence of overnutrition was 10.2% (8.2-12.6) at the national level and 11.9% (CI: 8.5-16.3), 8.4% (CI: 6.5-10.7) and 8.7% (CI: 5.2-14.3) in urban, rural and indigenous areas, respectively. The DBM prevalence was 1.4% (CI: 1.0-2.1) at the national level and 2.7% (CI: 1.4-5.1) in indigenous areas. Conclusions: Undernutrition is still the most prevalent malnutrition condition in our country. Panama has the highest prevalence of overnutrition in Central America. The highest prevalence of undernutrition and DBM was found among children living in indigenous areas.

RESUMO

Introducción. La isquemia mesentérica crónica es una entidad infrecuente, con una prevalencia de 0,03 %, donde más del 90 % son debidas a enfermedad arterioesclerótica que compromete principalmente la arteria mesentérica superior. Sus síntomas son dolor abdominal crónico y pérdida de peso, asociado a alteraciones imagenológicas que hacen el diagnóstico. El tratamiento depende de las condiciones clínicas del paciente y el número de vasos comprometidos. Es claro que la enfermedad multivaso sintomática requiere revascularización. Caso clínico. Mujer de 67 años, fumadora activa con antecedentes de hipertensión arterial y dislipidemia, con cuadro de crisis hipertensiva tipo urgencia que requirió manejo en Unidad de Cuidados Intensivos. Se hizo diagnóstico de aneurisma toracoabdominal Crawford IV, oclusión aorto-ilíaca (TASC D) y oclusión crónica del tronco celíaco y la arteria mesentérica superior. Por los síntomas de isquemia mesentérica crónica fue llevada a tratamiento quirúrgico con baipás aorto-bifemoral más baipás retrógrado a la arteria mesentérica superior por vía abierta. Resultado. La paciente tuvo mejoría de la sintomatología y aumentó 13 % del peso al seguimiento a los 3 meses. Conclusión. La isquemia mesentérica crónica es una condición subdiagnosticada, marcador de riesgo cardiovascular, con alta carga de morbilidad y mortalidad, en la cual, con una identificación temprana se puede ofrecer una terapia de revascularización, sea por vía endovascular o abierta, con el fin de mejorar la calidad de vida y la ganancia de peso, y evitar la necrosis intestinal.


Introduction. Chronic mesenteric ischemia is a rare entity, with a prevalence of 0.03%, where more than 90% are due to arteriosclerotic disease that mainly affects the superior mesenteric artery. Its symptoms are chronic abdominal pain and weight loss, associated with imaging alterations that make the diagnosis. Treatment depends on the patient's clinical conditions and the number of vessels involved. It is clear that symptomatic multivessel disease requires revascularization. Clinical case. A 67-year-old woman, an active smoker with a history of high blood pressure and dyslipidemia, presented with an emergency-type hypertensive crisis that required management in the Intensive Care Unit. A diagnosis of Crawford IV thoracoabdominal aneurysm, aorto-iliac occlusion (TASC D), and chronic occlusion of the celiac trunk and superior mesenteric artery was made. Due to the symptoms of chronic mesenteric ischemia, she underwent surgical treatment with aorto-bifemoral bypass plus retrograde bypass to the superior mesenteric artery via an open approach. Result. The patient had improvement in symptoms and gained 13% weight at 3-month follow-up. Conclusion. Chronic mesenteric ischemia is an underdiagnosed condition, a marker of cardiovascular risk, with a high burden of morbidity and mortality, in which, with early identification, revascularization therapy can be offered, either endovascularly or open, in order to improve quality of life and weight gain, and avoiding intestinal necrosis.

RESUMO

The intricate relationship between food systems and health outcomes, known as the food-nutrition-health nexus, intersects with environmental concerns. However, there's still a literature gap in evaluating food systems alongside the global syndemic using the complex systems theory, especially concerning vulnerable populations like children. This research aimed to design a system dynamics model to advance a theoretical understanding of the connections between food systems and the global syndemic, particularly focusing on their impacts on children under five years of age. The framework was developed through a literature review and authors' insights into the relationships between the food, health, and environmental components of the global syndemic among children. The conceptual model presented 17 factors, with 26 connections and 6 feedback loops, categorized into the following 5 groups: environmental, economic, school-related, family-related, and child-related. It delineated and elucidated mechanisms among the components of the global syndemic encompassing being overweight, suffering from undernutrition, and climate change. The findings unveiled potential interactions within food systems and health outcomes. Furthermore, the model integrated elements of the socio-ecological model by incorporating an external layer representing the environment and its natural resources. Consequently, the development of public policies and interventions should encompass environmental considerations to effectively tackle the complex challenges posed by the global syndemic.

RESUMO

OBJECTIVES: The present study aims to evaluate the impact of early exposure to brain injury and malnutrition on episodic memory and behavior. METHODS: For this, a systematic review was carried out in the Medline/Pubmed, Web of Science, Scopus, and LILACS databases with no year or language restrictions. RESULTS: Initially, 1759 studies were detected. After screening, 53 studies remained to be read in full. The meta-analysis demonstrated that exposure to double insults worsens episodic recognition memory but does not affect spatial memory. Early exposure to low-protein diets has been demonstrated to aggravate locomotor and masticatory sequelae. Furthermore, it reduces the weight of the soleus muscle and the muscle fibers of the masseter and digastric muscles. Early exposure to high-fat diets promotes an increase in oxidative stress and inflammation in the brain, increasing anxiety- and depression-like behavior and reducing locomotion. DISCUSSION: Epigenetic modifications were noted in the hippocampus, hypothalamus, and prefrontal cortex depending on the type of dietetic exposure in early life. These findings demonstrate the impact of the double insult on regions involved in cognitive and behavioral processes. Additional studies are essential to understand the real impact of the double insults in the critical period.

RESUMO

OBJECTIVE: To evaluate in a rural Tanzanian birth cohort the association between birth timing in relation to the preharvest lean season and early-life growth and cognitive development. STUDY DESIGN: Children were enrolled within 14 days of birth and followed up for 18 months. Child anthropometry was measured every 3 months. The Malawi Developmental Assessment Test was administered at the end of follow-up. We estimated the association between timing of birth in the context of other early childhood risk factors and both growth and Malawi Developmental Assessment Test scores. RESULTS: Children born in the preharvest months September and October had the lowest cognitive scores at 18 months, compared with birth in July and August (-1.05 change in overall Malawi Developmental Assessment Test development-for-age Z score, 95% CI: -1.23, -0.86). This association was observed for the language (-1.67 change in development-for-age Z score; 95% CI: -1.93, -1.40) and fine motor subcomponent scores (-1.67; 95% CI: -1.96, -1.38) but not for gross motor (-0.07; 95% CI: -0.23, 0.10) or social subcomponents (-0.07; 95% CI: -0.23, 0.10). Children born in September and October were the longest at birth but had the largest declines in growth Z scores during the first 6 months. CONCLUSIONS: There was a strong association between birth at the beginning of the preharvest season and poor growth and cognitive development. If these associations were mediated by the preharvest postnatal environment, targeted maternal and child interventions for children born during high-risk periods may improve these outcomes. TRIAL REGISTRATION: NCT03268902 (https://clinicaltrials.gov/study/NCT03268902).

RESUMO

To assess malnutrition contribution to the functional status and health related quality of life after hospitalization due to COVID-19 pneumonia, 66 selected adults referred for physical rehabilitation accepted to participate in the study; none of them required oxygen supply or had history of lung/musculoskeletal/neurological/immune/rheumatic disease or trauma, or contraindication for respiratory-function tests. At three evaluations, with 3 months in-between, assessments included: self-report of functional status, the St. George's Respiratory Questionnaire, spirometry, the 6-min-walk-test, the MRC-scale, the 30-s sit-to-stand-test, the timed-up-and-go-test, nutritional status, and ultrasound imaging (vastus medialis and diaphragm). At referral, patients had nutritional deficits with protein deficiency, which gradually improved; while muscle thickness (of both vastus medialis and diaphragm) increased, along with muscle strength and mobility (ANOVA, p < 0.05). Contrarywise, the distance covered during the 6-min-walk-test decreased (ANOVA, p < 0.05), with a negative influence from excess body mass. During rehabilitation, health-related quality of life and functional status improved, with negative influence from a history of tobacco use and referral delay, respectively. After hospitalization due to COVID-19, early diagnosis of both protein deficiency and decrease of skeletal muscle thickness could be relevant for rehabilitation, while pondering the negative impact of excess body mass on submaximal exercise performance.

RESUMO

Significance: The laparotomy is a common surgical procedure with a wide range of indications. Ideally, once the goals of surgery were achieved, the incision edges could then be approximated and the abdomen primarily closed. However, in some circumstances, it may be impossible to achieve primary closure, and instead the abdomen is intentionally left open. This review discusses the indications and objectives for the open abdomen (OA), summarizes the most common techniques for temporary abdominal closure, and illustrates treatment algorithms grounded in the current recommendations from specialty experts. Recent Advances: Still a relatively young technique, multiple strategies, and technologies have emerged to manage the OA. So too have the recommendations evolved, based on updated classifications that take wound characteristics into account. Recent studies have also brought greater clarity on recommendations for managing infection and malnutrition to support improved clinical outcomes. Critical Issues: The status of the OA can change rapidly depending on the patient's condition, the wound quality, and many other factors. Thus, there is a significant need for comprehensive treatment strategies that can be adapted to these developing circumstances. Future Directions: Treatment recommendations should be continuously updated as new technologies are introduced and old techniques fall out of use.

RESUMO

Sensory development is a complex process that can influence physiological and pathological factors. In laterally-eyed mammals, monocular enucleation (ME) during development and the subsequent lack of external sensory stimuli can result in permanent morphological and physiological changes. Malnutrition, especially in early life, also can cause permanent morphofunctional changes due to inadequate nutrient intake in both hemispheres. This study investigated the effects of early (postnatal day 7) ME and malnutrition during the suckling period on cortical excitability in adulthood (110-140 days of life). For this, we compared the speed propagation of cortical spreading depression in the occipital and parietal cortex of malnourished and well-nourished adult rats, previously suckled small-sized litters with three pups (L3/dam) medium-sized litters with six pups (L6/dam), and large-sized litters with twelve pups (L12/dam). The CSD velocity was augmented by the ME in the contralateral side of the removed eye in the parietal and occipital cortex. These findings suggest that visual sensory input deprivation is associated with permanent functional changes in the visual pathways, which can alter cortical excitability and lead to modifications in CSD propagation.

RESUMO

PURPOSE: This study aimed to investigate the impact of nutritional status and frailty phenotype and the predictors of temporal changes on health-related quality of life (HRQoL) of patients with bladder or kidney cancer. METHODS: Frailty phenotype, Patient-Generated Subjective Global Assessment, and Quality-of-life questionnaire Core-30 were applied twice to patients diagnosed with bladder or kidney cancer. Patients also completed a sociodemographic questionnaire, and clinical data were collected from records. RESULTS: Sixty-two individuals completed the study, mostly male, with a mean age of 62.5 (± 11.4) years. The median time of follow-up was 14.5 months. Role functioning, emotional functioning, and fatigue improved over time (p < 0.05). The factors that negatively affected the long-term quality of life summary score were being female, malnourished, pre-frail and frail, cancer treatment, performance status, and lower income. Using the multivariate model, being malnourished (ß = - 7.25; 95% CI, - 10.78 to - 3.71; p < 0.001), frail (ß = - 7.25; 95% CI, - 13.39 to - 1.11; p = 0.021), and each one-point increase in performance status (ß = - 6.9; 95% CI, - 9.54 to - 4.26; p < 0.001), were the ones that most negatively impacted the HRQoL between the two assessments. CONCLUSION: This study confirmed that frailty, nutritional status, and performance status are the main predictors of HRQoL of patients with bladder or kidney cancer over time. IMPLICATIONS FOR CANCER SURVIVORS: These findings may be the first step towards highlighting the importance of preventing malnutrition and frailty, in favor of a better long-term QoL for cancer patients.

RESUMO

The double burden of malnutrition (DBM) is a condition in which malnutrition coexists with overweight, reflecting a new layer of malnutrition. Our objectives were to assess prevalence; test associations between DBM and 24-hour movement behaviors; and investigate whether DBM is associated with clusters of social determinants. Methods: This multicenter cross-sectional study included 1152 adolescents (12 to 17 years old) from four Brazilian cities. Body mass index (BMI, kg/m2) was used to estimate overweight, and the adopted cutoff points took into account the curves established for age and sex: Z-score > 1 and ≤2 (overweight) and Z-score > 2 (obesity). The serum concentration of 25-hydroxyvitamin D [25(OH)D] was stratified into three levels: vitamin D deficiency ≤ 20 ng/mL; vitamin D insufficiency = 21-29 ng/mL; optimal vitamin D ≥ 30 ng/mL. We used multilevel Poisson regression models to estimate prevalence ratios (PRs) and their respective 95% confidence intervals (95%CI) and to analyze the association between DBM and covariates. A significance level of p < 0.05 was considered. Cluster analyses were performed by applying a combination of hierarchical and non-hierarchical methods. Results: A population prevalence of DBM of 7.3% (95% CI: 5.9-8.9) was revealed. A percentage of 19.2% (95% CI: 17.0-21.6) of adolescents were overweight, and 8.3% (95% CI: 6.8-10.1) were obese. A total of 41.5% (95% CI: 38.7-44.4) had vitamin D deficiency, and 25.8% (95% CI: 23.4-28.4) had vitamin D insufficiency. However, 24-hour movement behaviors were not associated with DBM. Adolescents living in the southern region of the country, from public schools whose mothers have higher education, have a 1.94 [PR = 2.94 (95% CI: 1.20-7.23)] times greater chance of developing DBM. These results highlight the importance of specific factors to improve the nutritional health of adolescents, considering the specific social determinants identified in this study.

RESUMO

Edible insects are recognized as promising food sources due to their nutritional composition. Some species, such as Gryllus assimilis, contain proteins, lipids, and carbohydrates of high biological value, which regulate several metabolic functions, including the Renin-Angiotensin System (RAS). In this context, the present study aimed to assess the effects of dietary supplementation with whole Gryllus assimilis powder on the metabolism of malnourished mice. Thirty-two male Swiss mice were used and divided into four treatment groups. The groups were identified as (AIN93-M); AIN93-M + Gryllus assimilis diet (AIN93-M + GA); AIN93-M + Renutrition diet (AIN93-M + REN) and AIN93-M + Renutrition diet + Gryllus assimilis (AIN93-M + REN + GA). The results showed that whole Gryllus assimilis powder inclusion promotes recovery from protein-energy malnutrition, reduces adiposity, and improves glucose tolerance and insulin sensitivity. It also reduces total cholesterol, triglycerides, VLDL, and adipocyte area. We also observed a significant increase in the expression of RAS-related genes, such as ACE2 and MasR, followed by a reduction in Angiotensinogen and ACE. The main findings of the present study suggest the use of black cricket as a viable strategy for the prevention and treatment of protein-energy malnutrition, as well as the reduction of adiposity, and improvement of lipid and glycemic parameters, with antihypertensive potential.

RESUMO

BACKGROUND: A compromised nutritional status jeopardizes a positive prognosis in acute lymphoblastic leukemia (ALL) patients. In low- and middle-income countries, ~ 50% of children with ALL are malnourished at diagnosis time, and undergoing antineoplastic treatment increases the risk of depleting their nutrient stores. Nutrition interventions are implemented in patients with cancer related malnutrition. We aimed to evaluate the effect of nutrition interventions in children diagnosed with ALL under treatment. METHODS: Using a predefined protocol, we searched for published or unpublished randomized controlled trials in: Cochrane CENTRAL, MEDLINE, EMBASE, LILACS, and SciELO, and conducted complementary searches. Studies where at least 50% of participants had an ALL diagnosis in children ≤ 18 years, active antineoplastic treatment, and a nutrition intervention were included. Study selection and data extraction were conducted independently by three reviewers, and assessment of the risk of bias by two reviewers. Results were synthesized in both tabular format and narratively. RESULTS: Twenty-five studies (out of 4097 records) satisfied the inclusion requirements. There was a high risk of bias in eighteen studies. Interventions analyzed were classified by compound/food (n = 14), micronutrient (n = 8), and nutritional support (n = 3). Within each group the interventions and components (dose and time) tested were heterogeneous. In relation to our primary outcomes, none of the studies reported fat-free mass as an outcome. Inflammatory and metabolic markers related to nutritional status and anthropometric measurements were reported in many studies but varied greatly across the studies. For our secondary outcomes, fat mass or total body water were not reported as an outcome in any of the studies. However, some different adverse events were reported in some studies. CONCLUSIONS: This review highlights the need to conduct high-quality randomized controlled trials for nutrition interventions in children with ALL, based on their limited number and heterogeneous outcomes.

RESUMO

This paper proposes a pseudo-birth-cohort approach to deal with a lack of longitudinal data to measure health inequities over time. Using Roemer's framework for inequality of opportunity, this study measures ex-ante and ex-post inequalities in malnutrition, a concept that spans both sides of the nutrition continuum. The total contribution of observed circumstances and the direct contribution of observed efforts to the variation of malnutrition are disentangled for people born between 1983 and 1988 in Mexico. Results indicate that inequality of opportunity has been persistent across this 30-year lifespan for that cohort. Some evidence suggests that a lack of opportunities has been transmitted from parents to children and that people's circumstances account for most of the explained variation in the double burden of malnutrition. However, stratifying the analysis by sex shows that efforts account for more of the explained variation of inequality of opportunity for women in their middle adulthood than for men in most of the outcomes analyzed.

RESUMO

Frailty and sarcopenia are well-recognized factors related to worse outcomes in patients with cirrhosis, including liver transplant (LT) candidates. Implications of pre-LT functional and muscle deterioration also affect post-LT outcomes. Patients with cirrhosis and acute-on-chronic liver failure (ACLF) have a lower survival rate, both before and after LT. There is a need to better identify those patients with ACLF who would benefit from LT. This review aims to present the available data about frailty and sarcopenia in patients with ACLF in the LT setting. An exhaustive review of the published literature was conducted. Data regarding frailty and sarcopenia in LT candidates with ACLF are scarce and heterogeneous. Studies evaluating frailty and sarcopenia in critically ill patients outside the liver literature are also presented in this review to enrich the knowledge of this field in expansion. Frailty and sarcopenia seem to contribute to worse outcomes in LT candidates with ACLF, both before and after LT. Sarcopenia evaluation may be the most prudent approach for those very sick patients. Skeletal muscle index assessed by computed tomography is recommended to evaluate sarcopenia. The role of muscle ultrasound and bioelectrical impedance analysis is to be determined. Frailty and sarcopenia are crucial factors to consider on a case-by-case basis in LT candidates with ACLF to improve patient outcomes.

RESUMO

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.

RESUMO

BACKGROUND: The present study aims to assess the interrater reliability of the Global Leadership Initiative on Malnutrition (GLIM) criteria, a framework to provide a consensus diagnosis of malnutrition. We also aimed to investigate its concurrent and predictive validity in the context of patients with cancer admitted to the intensive care unit (ICU). METHODS: Individuals aged ≥19 years with cancer who were admitted to the ICU within 48 h of their initial hospital admission were included. Nutrition status was assessed with the Nutritional Risk Screening 2002, the Subjective Global Assessment (SGA), and the GLIM criteria. Interrater reliability was assessed by the kappa test (>0.80). The SGA served as the established benchmark for assessing concurrent validity. To evaluate predictive validity, the occurrence of mortality within 30 days was the outcome, and Cox regression models were applied. RESULTS: A total of 212 patients were included: 66.9% were at nutrition risk, and 45.8% were malnourished according to the SGA. According to the GLIM criteria, 68.4% and 66% were identified as malnourished by evaluators 1 and 2, respectively (κ = 0.947; P < 0.001). The GLIM combination incorporating weight loss and the presence of inflammation exhibited sensitivity (82.4%) and specificity (92%). In the multivariate Cox regression models, most GLIM combinations emerged as independent predictors of complications. CONCLUSION: The GLIM criteria demonstrated satisfactory interrater reliability, and the combination involving weight loss and the presence of inflammation exhibited noteworthy sensitivity and specificity. Most GLIM combinations emerged as independent predictors of 30-day mortality.
