Abstract
Undernutrition is characterized by an imbalance of essential nutrients with an insufficient nutritional intake, a disorder in which the clinical manifestations in most cases are the result of the economic and social context in which the individual lives. In 1990, the study by the medical and humanitarian Naíde Teodósio (1915-2005) and coworkers, which formulated the Regional Basic Diet (RBD) model for inducing undernutrition, was published. This diet model took its origin from the observation of the dietary habits of families that inhabited impoverished areas from the Pernambuco State. RBD mimics an undernutrition framework that extends not only to the Brazilian population, but to populations in different regions worldwide. The studies based on RBD-induced deficiencies provide a better understanding of the impact of undernutrition on the pathophysiological mechanisms underlying the most diverse prevalent diseases. Indexed papers that are analyzed in this review focus on the importance of using RBD in different areas of knowledge. These papers reflect a new paradigm in translational medicine: they show how the study of pathology using the RBD model in animals over the past 30 years has and still can help scientists today, shedding light on the mechanisms of prevalent diseases that affect impoverished populations.

Abstract
: Undernutrition is a major public health problem leading to 1 in 5 of all deaths in children under 5 years. Undernutrition leads to growth stunting and/or wasting and is often associated with environmental enteric dysfunction (EED). EED mechanisms leading to growth failure include intestinal hyperpermeability, villus blunting, malabsorption and gut inflammation. As non-invasive methods for investigating gut function in undernourished children are limited, pre-clinical models are relevant to elucidating the pathophysiological processes involved in undernutrition and EED, and to identifying novel therapeutic strategies. In many published models, undernutrition was induced using protein or micronutrient deficient diets, but these experimental models were not associated with EED. Enteropathy models mainly used gastrointestinal injury triggers. These models are presented in this review. We found only a few studies investigating the combination of undernutrition and enteropathy. This highlights the need for further developments to establish an experimental model reproducing the impact of undernutrition and enteropathy on growth, intestinal hyperpermeability and inflammation, that could be suitable for preclinical evaluation of innovative therapeutic intervention.

Impact of acute undernutrition on growth, ileal morphology and nutrient transport in a murine model. ACTA ACUST UNITED AC 2016; 49:e5340.

Abstract
Undernutrition represents a major public health challenge for middle- and low-income
countries. This study aimed to evaluate whether a multideficient Northeast Brazil
regional basic diet (RBD) induces acute morphological and functional changes in the
ileum of mice. Swiss mice (∼25 g) were allocated into two groups: i) control mice
were fed a standard diet and II) undernourished mice were fed the RBD. After 7 days,
mice were killed and the ileum collected for evaluation of electrophysiological
parameters (Ussing chambers), transcription (RT-qPCR) and protein expression (western
blotting) of intestinal transporters and tight junctions. Body weight gain was
significantly decreased in the undernourished group, which also showed decreased
crypt depth but no alterations in villus height. Electrophysiology measurements
showed a reduced basal short circuit current (Isc) in the undernourished group, with no differences in transepithelial
resistance. Specific substrate-evoked Isc related to affinity and efficacy (glutamine and alanyl-glutamine) were
not different between groups, except for the maximum Isc (efficacy) induced by glucose. Transcription of Sglt1
and Pept1 was significantly higher in the undernourished group,
while SN-2 transcription was decreased. No changes were found in
transcription of CAT-1 and CFTR, while claudin-2 and occludin transcriptions were
significantly increased in the undernourished group. Despite mRNA changes, SGLT-1,
PEPT-1, claudin-2 and occludin protein expression showed no difference between
groups. These results demonstrate early effects of the RBD on mice, which include
reduced body weight and crypt depth in the absence of significant alterations to
villus morphology, intestinal transporters and tight junction expression.
