Cyanocobalamin, which plays an essential role in the body, is a synthetic form used in medical food. This present study aimed to develop an HPLC analysis method for determination cyanocobalamin and investigate the stability of cyanocobalamin in medical food. Validation of the developed method for cyanocobalamin was evaluated with linearity, LOD, LOQ, and accuracy. The linearity of this method was calculated with a value of the coefficient of determination (R2) ≥ 0.999. LOD and LOQ were 0.165 and 0.499 μg/kg, respectively. The recovery of medical food matrixes for accuracy was more than 97.63%. The validated method was applied for determining cyanocobalamin from medical foods. The developed method was used to examine the additives for cyanocobalamin protection. Ferric chloride and sorbitol alleviated cyanocobalamin degradation from heat and ascorbic acid. Especially, sorbitol showed a superior protective effect during the medical food production process. Therefore, this study suggests that sorbitol is a sweetener additive that prevents cyanocobalamin degradation by heat and the food matrix in medical food processing.

Background: Interventions simultaneously targeting multiple risk factors and mechanisms are most likely to be effective in preventing cognitive impairment. This was indicated in the Finnish Geriatric Intervention Study to Prevent Cognitive Impairment and Disability (FINGER) testing a multidomain lifestyle intervention among at-risk individuals. The importance of medical food at the early symptomatic disease stage, prodromal Alzheimer’s disease (AD), was emphasized in the LipiDiDiet trial. The feasibility and effects of multimodal interventions in prodromal AD are unclear. Objectives: To evaluate the feasibility of an adapted FINGER-based multimodal lifestyle intervention, with or without medical food, among individuals with prodromal AD. Methods: MIND-ADmini is a multinational proof-of-concept 6-month randomized controlled trial (RCT), with four trial sites (Sweden, Finland, Germany, France). The trial targeted individuals with prodromal AD defined using the International Working Group-1 criteria, and with vascular or lifestyle-related risk factors. The parallel-group RCT includes three arms: 1) multimodal lifestyle intervention (nutritional guidance, exercise, cognitive training, vascular/metabolic risk management and social stimulation); 2) multimodal lifestyle intervention+medical food (Fortasyn Connect); and 3) regular health advice/care (control group). Primary outcomes are feasibility and adherence. Secondary outcomes are adherence to the individual intervention domains and healthy lifestyle changes. Results: Screening began on 28 September 2017 and was completed on 21 May 2019. Altogether 93 participants were randomized and enrolled. The intervention proceeded as planned. Conclusions: For the first time, this pilot trial tests the feasibility and adherence to a multimodal lifestyle intervention, alone or combined with medical food, among individuals with prodromal AD. It can serve as a model for combination therapy trials (non-pharma, nutrition-based and/or pharmacological interventions).

Background. Protein-calorie deficiency is common multifactorial medical condition in infants. Nutrition therapy of protein-calorie deficiency in premature infants with special medical food is not always quite effective. It can be associated with residual manifestations of overlapping perinatal pathology.Clinical case description. Extremely premature child with severe protein-calorie deficiency in the late period with combined perinatal pathology (perinatal central nervous system damage and bronchopulmonary dysplasia) was administrated with therapeutic highly nutritious (high-protein/high-energy) milk formula according to individual plan. The positive dynamics in clinical manifestations of the main and associated diseases was noted on nutrition therapy.Conclusion. High-calorie and protein-enriched therapeutic formula can effectively correct protein-calorie deficiency in premature infants with associated perinatal pathology in the recovery period (disfunction compensation).

Abstract Background Propionic acidemia (PA), an inborn error of metabolism, is caused by a deficiency in propionyl-CoA carboxylase. Patients have to follow a diet restricted in the propiogenic amino acids isoleucine (Ile), valine (Val), methionine (Met) and threonine (Thr); proper adherence can prevent and treat acute decompensation and increase life expectancy. However, chronic complications occur in several organs even though metabolic control may be largely maintained. Bone marrow aplasia and anemia are among the more common. Materials and methods In this retrospective study, data for patients with PA being monitored at the Hospital Ramón y Cajal (Madrid, Spain) (n = 10) in the past 10 years were examined to statistically detect relationships between persistent severe anemia outside of metabolic decompensation episodes and dietary practices such as natural protein intake and medical food consumption (special mixture of precursor-free amino acids) along with plasma levels of branched-chain amino acids (BCAA). High ferritin levels were deemed to indicate that a patient had received repeated transfusions for persistent anemia since data on hemoglobin levels at the moment of transfusion were not always passed on by the attending centers. Results Three patients had severe, persistent anemia that required repeated blood transfusions. Higher medical food consumption and plasma Leu levels were associated with iron overload. Notably, natural protein intake and plasma Val were negatively correlated with ferritin levels. We also observed an inverse relationship between plasma Val/Leu and Ile/Leu ratios and ferritin. Conclusion The present results suggest that severe anemia in patients with PA might be associated with low natural protein intake and BCAA imbalance.

Objective: To research the biological impact on the endocannabinoid system (ECS) from dietary sources of [Formula: see text]-caryophyllene (BCP). This will encompass pre-clinical and clinical research for BCP. The bioavailability of BCP will be explored, focusing on bioavailability improvement. This research will establish if there is justification to warrant the development of a medical food for supporting the ECS through dietetic supplementation of BCP. Methods: Research and review papers were identified through the search engines Google Scholar, PubMed, and ScienceDirect. Main keywords included [Formula: see text]-caryophyllene, endocannabinoid system, dietary cannabinoids, cannabinoid type-2 receptor, and bioavailability. Results: The human body is limited in the digestion of BCP from food. This is because BCP is poorly absorbed in the gut. Everyone has different underlying endocannabinoid efficiency and most people do not have the full potential of supporting their ECS through diet. Conclusion: A medical food can be developed to use BCP with a delivery system, so that the bioactive food cannabinoid is readily absorbed. This will deliver dietary support to the ECS, that otherwise would be available from food. This review provides insight into the efficacy of using BCP in medical foods as dietary support for the ECS. Supporting the ECS can assist in maintaining homeostasis, regulating immune function, pain intensity, inflammatory markers, sleep patterns, mood, appetite, and stress susceptibility.

Background Novel wearable biosensors, ubiquitous smartphone ownership, and telemedicine are converging to enable new paradigms of clinical research. A new generation of continuous glucose monitoring (CGM) devices provides access to clinical-grade measurement of interstitial glucose levels. Adoption of these sensors has become widespread for the management of type 1 diabetes and is accelerating in type 2 diabetes. In parallel, individuals are adopting health-related smartphone-based apps to monitor and manage care. Objective We conducted a proof-of-concept study to investigate the potential of collecting robust, annotated, real-time clinical study measures of glucose levels without clinic visits. Methods Self-administered meal-tolerance tests were conducted to assess the impact of a proprietary synbiotic medical food on glucose control in a 6-week, double-blind, placebo-controlled, 2×2 cross-over pilot study (n=6). The primary endpoint was incremental glucose measured using Abbott Freestyle Libre CGM devices associated with a smartphone app that provided a visual diet log. Results All subjects completed the study and mastered CGM device usage. Over 40 days, 3000 data points on average per subject were collected across three sensors. No adverse events were recorded, and subjects reported general satisfaction with sensor management, the study product, and the smartphone app, with an average self-reported satisfaction score of 8.25/10. Despite a lack of sufficient power to achieve statistical significance, we demonstrated that we can detect meaningful changes in the postprandial glucose response in real-world settings, pointing to the merits of larger studies in the future. Conclusions We have shown that CGM devices can provide a comprehensive picture of glucose control without clinic visits. CGM device usage in conjunction with our custom smartphone app can lower the participation burden for subjects while reducing study costs, and allows for robust integration of multiple valuable data types with glucose levels remotely.

Abstract Obejctives Phenylketonuria (PKU) and hyperphenylalaninemia (HPHE) are metabolic disorders of phenylalanine (phe) metabolism due to the liver enzyme phe hydroxylase deficiency resulting in mental retardation. The only treatment of these disorders is the total or the partial breastfeeding replacement with special formula, respectively. Case presentation We aimed to evaluate the maternal stress degree in the two groups of mothers and compare the stress degree between mothers who were obliged to replace breastfeeding completely with those who replaced it partially. Mothers (n=50) were divided into two groups: n=25 with PKU and n=25 with HPHE infants. Mothers with PKU newborns were obliged to replace breastfeeding completely and feed their newborns with a common formula plus phe free medical food, whereas mothers with HPHE infants partially replaced breastfeeding with phe free medical food. Stress degrees were calculated using special questionnaire checklist by Bourne E. Psychological support was provided for both groups of mothers with stress. Conclusions Most mothers with PKU infants experienced high or severe stress, whereas mothers with HPHE newborns suffered from low and moderate symptoms and signs of stress. After psychological support most mothers with PKU newborns were ameliorated from stress symptoms; mothers with HPHE neonates experienced almost no stress symptoms. Mothers with PKU infants obliged to complete breastfeeding replacement experienced high and/or severe stress degrees as compared to mothers with HPHE newborns with partial breastfeeding replacement. Psychological support resulted in amelioration of both tested groups.
