Funded under the National Recovery and Resilience Plan (NRRP), Mission 4 Component 2 Investment 1.3, Theme 10.
Highlights
Profiling of vulnerable targets (in connection with SPOKE 5) through: a) analyses of existing data in children affected by obesity and ageing population at risk of malnutrition and non-communicable diseases (NCDs) b) screening of socioeconomic factors, lifestyle and dietary habits, environmental factors, food knowledge, nutritional status, body composition, functional status and disability, quality of life, genetic, metagenetic, phenotypic profiles, exposure to endocrine disruptors chemicals (EDCs), immune system functions in children and aging population with malnutrition c) human-derived biological samples analysis (including samples for the gut microbiome structure analysis and function).
Identification of sustainable tailored multidimensional approach including nutritional strategies aimed at reducing malnutrition in target specific populations by exploiting the interactions between environment, food, genotype and phenotype: a) analysis of the positive and negative interactions between lifestyle, socioeconomic status, clinical condition, psychological distress, medical treatment and diet for the implementation of sustainable dietary patterns; b) malnutrition biomarker validation; c) draft of sustainable nutritional protocols (in connection with Spoke 1 and 4).
Assessing microbiome–host interaction in malnutrition (in connection with Spoke 4 and 5). a) Evaluation of gut microbiome features in paediatric and ageing subjects affected by malnutrition and malnutrition-related conditions, with a focus on immune and metabolic pathways; b) Investigation of gut microbiome cell wall constituents on immune and metabolic pathways involved in human malnutrition; c) Investigation of the diet, environmental factors and drugs influencing human gut microbiome structure and function; d) Design of an algorithm to predict the risk of gut dysbiosis associated with malnutrition and malnutrition-related diseases.

Profiling of gut bacterial constituents with potential applications as postbiotics aimed at restoring immune system and metabolic functions in vulnerable subjects with malnutrition (M36)
Obesity can independently lead to loss of muscle mass and function, due to the negative impact of adipose tissue-dependent metabolic derangements, such as oxidative stress, inflammation, and insulin resistance. Additionally, individuals with obesity have a high prevalence of chronic non-communicable diseases that negatively impact muscle metabolism (both anabolism and catabolism).
On the other hand, sarcopenia may directly facilitate fat accumulation through reduced total energy expenditure, and obesity and sarcopenia may therefore synergistically enhance one another with vicious cycling of fat gains and muscle loss through reduced mobility, dependency and disability.
From a clinical standpoint, SO potentially leads to a cumulative risk derived from the two individual clinical situations.
At the moment profiling of SO subjects considering the etiological factors, the pathophysiological aspects and shared/validated therapeutic approaches are lacking.
