Introduction: The synergistic impact of coexistent malnutrition and sarcopenia on morality in hospitalized patients with decompensated cirrhosis remains elusive. This prospective cohort study aimed to delineate the prevalence concerning coexistence of malnutrition and sarcopenia and the prognosticating role on long-term mortality among cirrhosis.

Methods: Adult cirrhotic patients with decompensated episodes between 2019 and 2021 were consecutively enrolled. Malnutrition and sarcopenia were diagnosed according to the Global Leadership Initiative on Malnutrition (GLIM) criteria and the European Working Group on Sarcopenia in Older People (EWGSOP2) algorithm, respectively. The entire cohort was divided into three groups: non-malnutrition and non-sarcopenia (NN), malnutrition or sarcopenia, and coexistent malnutrition and sarcopenia (MS). Log-rank test and multivariate Cox regression model were utilized to evaluate survival status and independent risk factors for mortality, respectively.

Results: Our findings indicated that malnutrition manifested in 44.6% of inpatients with decompensated cirrhosis, while sarcopenia presented in 16.4% of the entire cohort, indicative of a prevalence of 14.7% regarding coexistent malnutrition and sarcopenia. The Kaplan-Meier graphic demonstrated a significant difference regarding survival curves among the three groups, referring to the MS group presented with the lowest survival rate (log-rank test: p < 0.001). Moreover, coexistent malnutrition and sarcopenia were associated with nearly 4 times higher mortality risk (model 1: hazard ratio [HR] = 3.31, 95% confidence interval [CI]: 1.20-9.13, p = 0.020; model 2: HR = 4.34, 95% CI: 1.52-12.4, p = 0.006) in comparison with patients without any condition (NN group).

Conclusions: Malnutrition and sarcopenia had superimposed negative impacts on inpatients with decompensated cirrhosis. It is imperative to identify this vulnerable subset to provide prompt therapeutic intervention for better prognosis.

Introduction: Patients with exacerbated chronic obstructive pulmonary disease (COPD) have a reduced ability to perform activities of daily living (ADLs). Rehabilitation programs (RPs) and nutritional therapy may affect the ability to perform ADLs.

Objective: The objective of the study was to clarify the factors associated with reduced ability to perform ADLs in patients with COPD exacerbation.

Subjects/methods: A multivariate analysis of 75 patients (mean age, 77 years) with COPD exacerbation, divided into the Barthel index (BI) decline (△BI decreased ≥15) and without BI decline (△BI decreased ≤10) groups, was performed. Patient characteristics, duration before RP initiation, functional variables, and nutrition-related variables were compared between the groups.

Results: The degree of dyspnea and serum albumin levels before and at RP initiation were significantly lower in the BI decline group. The Hoffer classification score and duration between hospital admission and RP initiation were significantly higher and longer, respectively, in the BI decline group. The duration between hospital admission and RP initiation and dietary intake at RP initiation were independent predictors of reduced ability to perform ADLs.

Conclusions: Early RP initiation and aggressive nutritional therapy may mitigate the risk of reduced ability to perform ADLs, thus decreasing dependence and disability in patients with COPD exacerbation.

Introduction: Glutamate is a representative taste molecule with an umami flavor and is a major nutrient found abundantly in nature. Furthermore, it plays a significant role in the human body as a key metabolic intermediate and neurotransmitter. Therefore, the divergence of glutamate functions among populations during their evolution is of particular interest with a hypothesis that the genetic variation can lead to understanding divergence in taste perception. To elucidate variation in glutamate applications and to deepen our understanding of taste perception, we examined the nucleotide diversity of genes associated with glutamate sensing and metabolism among human populations.

Methods: We first established 67 genes related to glutamate sensing and metabolism based on the database and literature survey. Then, for those genes, we used a population genomics approach based on ten populations over 76,156 human genomes in the gnomAD database.

Results: Statistical tests of means and medians of the minor allele frequencies did not show any significant difference among populations. However, we observed substantial differences between two functional groups, glutamate sensing and glutamate metabolism, in populations of Latino/admixed American, Ashkenazi Jewish, and Others. Interestingly, we could find significant differences between the African population and the East Asian population at the single nucleotide polymorphism level of glutamate metabolism genes, but no clear differences were noted in glutamate-sensing genes. These suggest that glutamate-sensing genes are under the functional constraint compared to glutamate metabolism genes.

Conclusion: Thus, glutamate-sensing genes and metabolism genes have a contrasting mode of the evolution, and glutamate-sensing genes are conservatively evolved, indicating its functional importance.

Introduction: Home parenteral nutrition (HPN) is a rare but challenging therapy for patients with mostly severe underlying diseases. We aimed to investigate patient-reported health-related quality of life (QOL) of patients receiving HPN and its development over time in particular.

Methods: We assessed QOL of HPN patients in a prospective multicenter observational study (SWISSHPN II study). We designed a questionnaire to record symptoms and negative impacts of HPN and completed the validated Optum® SF-36v2® Health Survey with the patients.

Results: Seventy patients (50% women) on HPN were included. HPN commonly affected feelings of dependency (n = 49, 70%), traveling/leaving home (n = 37, 53%), attending cultural and social events (n = 25, 36%), and sleep (n = 22, 31%). Most frequently reported symptoms were diarrhea (n = 30, 43%), polyuria (n = 28, 40%), nausea/emesis (n = 27, 39%), dysgeusia (n = 23, 33%), and cramps (n = 20, 29%). At baseline, mean (standard deviation) SF-36v2® physical and mental health component summary scores (PCS and MCS) were 45 (20) and 57 (19), respectively, and there was a trend toward improvement in PCS over the study period, while MCS remained stable. Satisfaction with health care professionals involved in HPN care was high.

Conclusion: QOL is a crucial and decisive aspect of HPN patient care. Symptoms related to the underlying disease and PN are frequent. Impaired social life and an ambivalent attitude toward the life-saving therapy are major concerns for these patients and should be addressed in their care.

The following document is dedicated to compiling the abstracts of the communications and lectures of the FINUT 2022 Conference. The document comprises 111 abstracts of the guest speakers participating in the scientific symposia and special lectures and more than 230 abstracts for oral and poster communications, representing more than 20 countries. FINUT Conferences seek to open a place for contrasted science shared by the Ibero-American region, a necessary space to open opportunities and to display the research work done in Food and Nutrition. The main objective of the FINUT 2022 Conference is to create a space for the exchange and discussion of ideas related to the main challenges of Food and Nutrition in Iberoamerica, in order to offer solutions aimed at improving the health status of populations, taking into account the impact of social inequalities in the region. The scientific program of the Conference includes 40 parallel symposia, 5 breakfasts with the experts, and 11 special lectures. In this second edition the Conference focused on 4 topics: • Healthy Nutrition in the Life Cycle and Clinical Nutrition • Nutritional Epidemiology and Public Health Challenges in Iberoamerica • Safe, Healthy, Sustainable, and Social Food • Methods and Tools in Nutrition The entity organizing the Conference is the Ibero-American Nutrition Foundation (FINUT) which was established in 2011. FINUT is a non-profit and financially self-supporting entity; our vision is to promote research and training, identify problems of public interest and provide scientific answers; and involve all stakeholders in our cause. We work throughout the year in many scientific virtual activities with a large number of beneficiaries and the FINUT Conferences give us the opportunity to meet them personally. We wish to thank the Organizing, Scientific, and Local Committees for the enthusiasm and commitment dedicated to this conference, our sponsors for trusting us again, and take the opportunity we offer them to contact the most valuable part of our event, the delegates; professionals, academics, clinicians, researchers, and students in the areas of Food, Nutrition, and Health, to whom we also extend our most sincere gratitude. ¡See you at FINUT 2024!
