Aims/IntroductionAdipose tissue‐derived hormones are associated with metabolic disorders including type 2 diabetes mellitus. The present study investigated the levels of adiponectin and pro‐inflammatory cytokines including tumor necrosis factor‐α (TNF‐α), interleukin‐1 beta (IL‐1β) and IL‐10 in Vietnamese patients with type 2 diabetes mellitus, and their correlations with clinical parameters of overweight and type 2 diabetes mellitus.Materials and MethodsBased on body mass index, 73 patients with type 2 diabetes mellitus were categorized either as overweight or non‐overweight. As healthy controls, 57 overweight and non‐overweight individuals without type 2 diabetes mellitus were included. The adiponectin, TNF‐α, IL‐1β and IL‐10 levels were measured in the sera samples in all study participants by enzyme‐linked immunosorbent assay and were correlated with clinical parameters.ResultsThe adiponectin levels were lower in patients with type 2 diabetes mellitus (2.5 ± 1.5 μg/mL) compared with controls (16 ± 18.6 μg/mL; P < 0.0001), and were decreased in overweight individuals compared with those who were not overweight. The TNF‐α and IL‐1β levels were increased, whereas the IL‐10 levels were decreased in patients with type 2 diabetes mellitus and in overweight controls compared with non‐overweight controls (P < 0.0001). The adiponectin levels were correlated with the TNF‐α, IL‐1β, IL‐10 levels, and the clinical parameters of overweight and type 2 diabetes mellitus. The quantitative insulin sensitivity check index and homeostasis model assessment insulin resistance indexes were correlated with the relative ratios of adiponectin/TNF‐α, adiponectin/IL‐1β, adiponectin/IL‐10, TNF‐α/IL‐10 and IL‐1β/IL‐10.ConclusionsAdiponectin and pro‐inflammatory cytokines are associated with type 2 diabetes mellitus, and might serve as a prognostic marker and a therapeutic intervention for overweight‐related type 2 diabetes mellitus.

Traditional complementary foods (CF) with a low nutrient density have been implicated in growth faltering, stunting, and other adverse outcomes in children. The efficacy of 2 types of locally produced, micronutrient-fortified CF to prevent stunting of infants living in rural Vietnam was evaluated. In a village-randomized controlled study, 426 infants, 5 mo of age, received for 6 mo a fortified CF, either as an instant flour (FF) or a food complement (FC) in village canteens, or traditional CF at home (C). After 6 mo of intervention, weight, length, length-for-age Z-score (LAZ) and weight-for-age Z-score were greater in the 2 intervention groups compared with the C group, with an estimated effect of +0.22 LAZ for the FF group and +0.21 LAZ for the FC group. At the last follow-up, 18 mo after the intervention, there was no significant difference in height-for-age Z-score (HAZ) between the groups, even though the HAZ in the FF group was 0.17 greater than that in the C group (P = 0.18). In contrast, the weight-for-height Z-score and BMI Z-score, indices of ponderal growth, were greater in the FF group (-0.49 and -0.26, respectively) than in the FC group (-0.73 and -0.49, respectively), with Z-scores in the C group intermediate and not significantly different from the others. This study shows that regular provision of locally produced CF fortified with micronutrients partly stopped growth faltering in Vietnamese infants, with differential effects on long-term length and ponderal growth. Providing only micronutrients instead of a complete array of nutrients might result in only short-term length growth benefits.

Adding amylase to fortified blended foods can improve energy density, and increase child's energy and nutrient intake. The efficacy of this strategy is unknown for the World Food Programme's Super Cereal Plus (SC+) and Super Cereal (SC) blends. The primary goal of this study was to investigate the increased energy intake from amylase‐containing SC+ and SC compared to control porridges in Burkinabe children. Secondly, energy intake from amylase‐containing porridges compared to CERELAC®, Vitazom, and eeZeeBAR™ was studied. Thirdly, caregivers' (n = 100) porridge acceptability was investigated. The design was a randomized double‐blind controlled cross‐over trial studying the effect of amylase addition to SC+ and SC flours on porridge energy and nutrient intake in healthy Burkinabe children aged 12–23 (n = 80) and 24–35 months (n = 40). Amylase added to porridges increased energy density from 0.68 to 1.16 kcal/g for SC+ and from 0.66 to 1.03 kcal/g for SC porridges. Among children aged 12–23 months, mean energy intake from all porridges with amylase (135–164 kcal/meal) was significantly higher compared to control SC+ porridges (84–98 kcal/meal; model‐based average). Among children aged 24–35 months, mean energy intakes were also significantly higher from all porridges with amylase added (245–288 kcal/meal) compared to control SC porridges (175–183 kcal/meal). Acceptability of the porridges among caregivers was rated neutral to good, both for amylase‐added and non‐amylase‐containing porridges. These findings suggest that, among 12–35‐month‐old, adding amylase to fortified blended foods significantly increased energy and consequently nutrient intake per meal by 67% for SC+ and 47% for SC. Moreover, amylase‐containing porridges were well accepted by the caregivers.

BackgroundAdipokines are involved in the pathogenesis of metabolic disorders including obesity and type 2 diabetes mellitus (T2DM). This study investigates the levels of leptin, resistin, visfatin, secreted frizzled-related protein 5 (SFRP5), monocyte chemoattractant protein-1 (MCP-1) and retinol-binding protein 4 (RBP4) and their correlations with clinical parameters of overweight and T2DM.MethodsWe recruited overweight 50 patients with T2DM, 88 non-overweight patients with T2DM, 29 overweight and 100 non-overweight individuals devoid of T2DM for this study. The levels of studied adipokines were measured by enzyme-linked immunosorbent assay and correlated with clinical parameters.ResultsThe levels of MCP-1 and SFRP5 were decreased while visfatin and RBP4 levels were increased in patients with T2DM compared to those in the control individuals (P < 0.01). Among patients with T2DM, leptin and resistin levels were higher while RBP4 levels were lower in patients with overweight T2DM compared to those in patients with non-overweight T2DM (P < 0.0001, 0.019 and 0.05, respectively). Leptin and MCP-1 levels were correlated with HOMA-IR, QUICKI and HOMA-β. Leptin/MCP-1 ratio was correlated with insulin levels, HOMA-IR and HOMA-β indexes. Resistin/RBP4, visfatin/MCP-1 and MCP-1/RBP4 ratios were strongly correlated with the levels of fasting glucose, HbA1c and HOMA-β. In addition, ROC curve analyses indicated a diagnostic potential of resistin/RBP4 and MCP-1/RBP4 indexes for T2DM (AUC = 0.81 and 0.83, respectively) and β-cell function (AUC = 0.76 and 0.74, respectively).ConclusionsAdipokines (leptin, resistin, visfatin, SFRP5, MCP-1, and RBP4) are associated with overweight and T2DM and may serve as a potential prognostic marker and therapeutic intervention for overweight-related T2DM.

To investigate whether an intervention including micronutrient-fortified complementary foods can improve iron status, we conducted a randomized controlled trial in 5-mo-old Vietnamese infants (n = 246). Villages (n = 29) were randomly divided into those receiving instant flour (FF) or a food complement (FC) both fortified with micronutrients or nothing [control (C)]. FF and FC infants received daily for 6 mo at least 2 meals of fortified complementary foods. Micronutrient status was assessed by measurement of hemoglobin (Hb) and plasma ferritin (PF), transferrin receptor, zinc, and retinol. Final Hb (mean ± SD) was higher in the FF (112.5 ± 8.0 g/L) and FC (114.0 ± 7.0 g/L) groups compared with C (109.0 ± 8.0 g/L; P = 0.006). PF (geometric mean [95% CI]) was also higher in FF (19.8 μg/L [17.5-22.3]) and FC (20.8 μg/L [18.3-23.6]) compared with C (11.1 μg/L [9.8-12.5]; P < 0.0001). Anemia prevalence decreased more in the FC group (-43.6%) compared with C (-10.3%; P = 0.006). The change in prevalence of PF < 12 μg/L was different in the FF (-16.4%) and FC (-6.7%) groups compared with C (+30.4%; P < 0.01). Endpoint prevalence of iron deficiency (ID) and ID anemia (IDA) were lower in the FF (13.4 and 6.7%, respectively) and FC (15.2 and 3.8%) groups compared with C (57.5 and 37.5%) (P < 0.0001). Retinol and zinc concentrations did not differ among groups, but endpoint prevalence of zinc deficiency was lower in FF infants (36.1%) than in C infants (52.9%; P = 0.04). Micronutrient-fortified complementary foods significantly improved iron status and decreased the prevalence of anemia, ID, and IDA in Vietnamese infants and can be an important tool to reduce ID in infancy in developing countries.
