Dobryk, D, Dobryk, O, Dobryanskyy, D
Georgian medical news. 2022;(323):94-101
Abstract
Premature infants are at high risk for diseases associated with impaired adaptation of the immature digestive tract, such as necrotizing enterocolitis (NEC) or late-onset sepsis (LOS), as well as severe neonatal morbidities associated with these diseases. This study was aimed to evaluate the effectiveness of prophylactic enteral use of bovine lactoferrin for the prevention of severe neonatal diseases in premature infants. The prospective cohort study included 117 premature infants with gestational age (GA) of ≤32 weeks, a birth weight of ≤1,500 g, and an age of ≤72 hours. 27 infants who were receiving enteral feeds were randomized to receive lactoferrin at a dose of 100 mg/day until postmenstrual age (PMA) of 36 weeks or discharge (at least 4 weeks). 90 infants formed the control group and received standard treatment. The primary outcome was the incidence of LOS, the secondary outcomes were the incidence of necrotizing enterocolitis (NEC), retinopathy of prematurity (ROP), severe brain damage, bronchopulmonary dysplasia (BPD), overall mortality, as well as the age of achieving full enteral feeds, duration of antibacterial therapy, length of stay in NICU and the total length of hospital stay. Enteral lactoferrin supplementation did not reduce the incidence of LOS (29.6% in the lactoferrin group against 22.7% in the control group; p=0.85), NEC (5.6% vs. 1.8%, respectively; p=0.11) and overall mortality (18.5% vs. 9.1%, respectively; p=0.06), as well as the incidence of severe intraventricular hemorrhages (18.5% vs. 9.8%, respectively; p=0.17), PVL (11.1% vs. 2.2%, respectively; p=0.17) and BPD (14.8% vs. 25.6%, respectively; p = 0.25). Infants receiving lactoferrin were achieving full enteral feeds significantly faster compared to the control group (14 (10-17) days vs. 19 (13-32) days, respectively; p=0.007). The total length of hospital stay of infants with GA ≤28 weeks in the lactoferrin group was significantly shorter compared to the control group (74 (68-89) vs. 98 (83-109) days, respectively; p=0.048). Enteral lactoferrin supplementation at a dose of 100 mg/day does not affect the main morbidity and mortality of prematurely born infants with GA ≤ 32 weeks but may facilitate significantly faster achievement of the full enteral feeds and the reduction of the length of hospital stay in the tiniest infants.

Abstract
Dietary advice constitutes a treatment strategy for irritable bowel syndrome (IBS). We aimed to examine the effect of a starch- and sucrose-reduced diet (SSRD) on gastrointestinal symptoms in IBS patients, in relation to dietary intake and systemic inflammatory parameters. IBS patients (n = 105) were randomized to a 4-week SSRD intervention (n = 80) receiving written and verbal dietary advice focused on starch and sucrose reduction and increased intake of protein, fat and dairy, or control group (n = 25; habitual diet). At baseline and 4 weeks, blood was sampled, and participants filled out IBS-SSS, VAS-IBS, and Rome IV questionnaires and dietary registrations. C-reactive protein and cytokines TNF-α, IFN-γ, IL-6, IL-8, IL-10, and IL-18 were analyzed from plasma. At 4 weeks, the intervention group displayed lower total IBS-SSS, 'abdominal pain', 'bloating/flatulence' and 'intestinal symptoms´ influence on daily life' scores (p ≤ 0.001 for all) compared to controls, and a 74%, responder rate (RR = ΔTotal IBS-SSS ≥ -50; RRcontrols = 24%). Median values of sucrose (5.4 vs. 20 g), disaccharides (16 vs. 28 g), starch (22 vs. 82 g) and carbohydrates (88 vs. 182 g) were lower for the intervention group compared to controls (p ≤ 0.002 for all), and energy percentages (E%) of protein (21 vs. 17 E%, p = 0.006) and fat (47 vs. 38 E%, p = 0.002) were higher. Sugar-, starch- and carbohydrate-reductions correlated weakly-moderately with total IBS-SSS decrease for all participants. Inflammatory parameters were unaffected. IBS patients display high compliance to the SSRD, with improved gastrointestinal symptoms but unaltered inflammatory parameters. In conclusion, the SSRD constitutes a promising dietary treatment for IBS, but needs to be further researched and compared to established dietary treatments before it could be used in a clinical setting.

Moon, JM, Finnegan, P, Stecker, RA, Lee, H, Ratliff, KM, Jäger, R, Purpura, M, Slupsky, CM, Marco, ML, Wissent, CJ, et al
Nutrients. 2021;(7)
Abstract
Glucosamine (GLU) is a natural compound found in cartilage, and supplementation with glucosamine has been shown to improve joint heath and has been linked to reduced mortality rates. GLU is poorly absorbed and may exhibit functional properties in the gut. The purpose of this study was to examine the impact of glucosamine on gastrointestinal function as well as changes in fecal microbiota and metabolome. Healthy males (n = 6) and females (n = 5) (33.4 ± 7.7 years, 174.1 ± 12.0 cm, 76.5 ± 12.9 kg, 25.2 ± 3.1 kg/m2, n = 11) completed two supplementation protocols that each spanned three weeks separated by a washout period that lasted two weeks. In a randomized, double-blind, placebo-controlled, crossover fashion, participants ingested a daily dose of GLU hydrochloride (3000 mg GlucosaGreen®, TSI Group Ltd., Missoula, MT, USA) or maltodextrin placebo. Study participants completed bowel habit and gastrointestinal symptoms questionnaires in addition to providing a stool sample that was analyzed for fecal microbiota and metabolome at baseline and after the completion of each supplementation period. GLU significantly reduced stomach bloating and showed a trend towards reducing constipation and hard stools. Phylogenetic diversity (Faith's PD) and proportions of Pseudomonadaceae, Peptococcaceae, and Bacillaceae were significantly reduced following GLU consumption. GLU supplementation significantly reduced individual, total branched-chain, and total amino acid excretion, with no glucosamine being detected in any of the fecal samples. GLU had no effect on fecal short-chain fatty acids levels. GLU supplementation provided functional gut health benefits and induced fecal microbiota and metabolome changes.

Abstract
BACKGROUND Inclusion of dairy in diet patterns has been shown to have mixed effects on weight loss. A prevailing hypothesis is that dairy improves weight loss by influencing endocrine systems associated with satiety and food intake regulation. OBJECTIVES The objective of the current study was to evaluate the effect of weight loss with or without adequate dietary dairy on subjective and objective appetitive measures. METHODS Men and women who were habitual low dairy consumers (n = 65, 20-50 y) participated in a 12-wk randomized controlled feeding weight loss trial. During the 12-wk intervention, a low-dairy (<1 serving dairy/d) was compared with an adequate-dairy (3-4 servings dairy/d) diet, both with a 500-kcal deficit/d. Test days, before and at the end of the intervention, began with 2 fasting blood draws and visual analog scale (VAS) measures, followed by a standard breakfast (25% of prescribed restricted calories), 5 postbreakfast blood draws and VASs, a standard lunch (40% of restricted energy amount), and 12 postlunch blood draws and VASs. Blood samples were used for satiety hormone measurements. On a separate day when matching standard meals were consumed, an ad libitum buffet meal was provided as dinner, at a self-selected time. Meal duration and intermeal interval were recorded. RESULTS Weight loss (-6.1 kg), irrespective of dairy, resulted in reduced fasting insulin (-20%) and leptin (-25%), and increased fasting acylated ghrelin (+25%) and VAS desire to eat (+18%) (P < 0.05). There were no effects of dairy on objective or subjective satiety measures. Weight loss marginally reduced the intermeal interval (289 min compared with 276 min, P = 0.059) between lunch and the ad libitum buffet. CONCLUSIONS These results do not support the hypothesis that inclusion of dairy in long-term dietary patterns influences appetite during weight loss. Weight loss per se has a modest impact on select systems that regulate hunger and satiety.This trial was registered at clinicaltrials.gov as NCT00858312.

Abstract
World health trends are focusing on a balanced food and beverage intake for healthy life. Refined deep-sea water (RDSW), obtained from deep-sea water collected offshore in Muroto (Japan), is mineral-rich drinking water. We previously reported that drinking RDSW improves human gut health. Here, we analyzed the effect of drinking RDSW on the gut ecosystem to understand this effect. This was a randomized double-blind controlled trial. Ninety-eight healthy adults were divided into two groups: RDSW or mineral water (control). The participants consumed 1 L of either water type daily for 12 weeks. A self-administered questionnaire and stool and urine samples were collected through the intervention. The following were determined: fecal biomarkers of secretory immunoglobulin A (sIgA), five putrefactive products, and nine short-chain-fatty-acids (SCFAs) as the primary outcomes; and three urinary isoflavones and the questionnaire as secondary outcomes. In post-intervention in the RDSW group, we found increased concentrations of five SCFAs and decreased concentrations of phenol and sIgA (p < 0.05). The multiple logistic analysis demonstrated that RDSW significantly affected two biomarkers (acetic and 3-methylbutanoic acids) of the five SCFAs mentioned above (p < 0.05). Similarly, the concentrations of urinary isoflavones tended to increase in post-intervention in the RDSW group. Constipation was significantly alleviated in the RDSW group (94%) compared with the control group (60%). Drinking RDSW improves the intestinal environment, increasing fecal SCFAs and urinary isoflavones, which leads to broad beneficial effects in human.

Abstract
OBJECTIVES The determinants of gut microbiota composition and its effects on common childhood illnesses are only partly understood, especially in low-income settings. The aim of the present study was to investigate whether morbidity predicts gut microbiota composition in Malawian children and whether microbiota predicts subsequent morbidity. We tested the hypothesis that common infectious disease symptoms would be predictive of lower microbiota maturity and diversity. METHODS We used data from 631 participants in a randomized-controlled nutrition intervention trial, in which a small-quantity lipid-based nutrient supplement was provided to pregnant and lactating mothers and their children at 6 to 18 months of age. Fecal samples were collected from the children at 6, 12, 18, and 30 months of age and analyzed using 16S rRNA sequencing. Microbiota variables consisted of measures of microbiota diversity (Shannon Index), microbiota maturity (microbiota-for-age z score), and the relative abundances of taxa. Morbidity variables included gastrointestinal and respiratory symptoms and fever. RESULTS Diarrhea and respiratory symptoms from 11 to 12 months were predictive of lower microbiota-for-age z score and higher Shannon Index, respectively (P = 0.035 and P = 0.023). Morbidity preceding sample collection was predictive of the relative abundances of several bacterial taxa at all time points. Higher microbiota maturity and diversity at 6 months were predictive of a lower incidence rate of fever in the subsequent 6 months (P = 0.007 and P = 0.031). CONCLUSIONS Our findings generally do not support the hypothesis that morbidity prevalence predicts a subsequent decrease in gut microbiota maturity or diversity in rural Malawian children. Certain morbidity symptoms may be predictive of microbiota maturity and diversity and relative abundances of several bacterial taxa. Furthermore, microbiota diversity and maturity may be associated with the subsequent incidence of fever.

Abstract
OBJECTIVE Recent advances in the translational research showed that dietary nutrients have critical importance to the microbioma balance in the gastrointestinal tract. Therefore, the alteration of the intestinal microbiota in order to achieve, restore, and maintain favorable balance in the ecosystem, and the activity of microorganisms present in the gastrointestinal tract is necessary for the improved health condition of the host. The objective of this translational study was to evaluate, in a pediatric population, the efficacy and safety of prophylactic probiotics for a better nutritional absorption capacity in the view to enhance their overall health and immunity. PATIENTS AND METHODS A total of 40 pediatric patients between the ages of 14 and 18 years were enrolled in the study and divided under two categories (treated/active group and placebo group). Three-time points clinical evaluations were performed: a baseline assessment (Time 0), a second evaluation at 5 weeks after the start of probiotic use (Time 1), and a final evaluation at the timeline after 10 weeks (Time 2). In the initial phase of the study, the recruited subjects underwent a panel of initial T0 clinical tests. For each of the patients, a blood sample was taken in order to evaluate the following biochemical measurements: Vitamin D, Vitamin A, Calcium, Zinc, and Iron. Moreover, an initial nutritional evaluation was carried out through which the nutritionist estimated the body composition of the subject (weight and body mass index), the caloric needs and dietary behaviour of each recruited patient. RESULTS Eligible participants were randomized into placebo (n = 20) or treated/active (n = 20) treatment conditions by random allocation using a computerized random number generator, ensuring all investigators remained blind to the treatment distribution. The data were compared within and between groups using statistical methods. The results confirmed that the probiotic supplementation was effective in increasing the overall blood biomarkers levels of vitamins, calcium, and mineral absorption from baseline to 10 weeks of treatment, compared with the placebo. CONCLUSIONS Probiotics may be suggested as supplements to improve biomarkers serum concentration if administered for a period of at least ≥ 5 weeks. However, further studies are required for optimal recommendations in patient treatment.

Fukatsu, K, Shineha, R, Kawauchi, Y, Saeki, M, Nakayama, M
Annals of nutrition & metabolism. 2019;(3):189-199
Abstract
INTRODUCTION Though micronutrient formulations for parenteral nutrition (PN) have been revised, the impacts of these changes on nutritional parameters, blood micronutrient levels, and safety have yet to be clarified. We examined the efficacy and safety of a new PN formulation with a micronutrient composition based on the Food and Drug Administration 2000 recommendation in surgical patients. METHODS This phase III clinical trial (JapicCTI-No. 142610) was a prospective, randomized, controlled, parallel-group, open-label, multicenter study. Two types of PN, OPF-108 (revised formula, n = 51) and ELN (previous formula mainly based on American Medical Association 1975 guidelines, n = 59), were given to patients from POD1 or 2 to POD7 after surgery. OPF-108 contains more vitamin B1, B6, C, and folic acid, a much lower dose of vitamin K, and less iron than ELN. Nutritional parameters and micronutrient profiles in blood and safety were evaluated. RESULTS Nutritional parameters on POD5 and 8 were similar between the 2 groups. Blood vitamin B1, B6, and folic acid levels on POD 5 and 8 were higher in the OPF-108 group than in the ELN group. Only OPF-108 restored vitamin C levels to within the normal range on POD5 and 8. Vitamin K levels far exceeded the upper limit of the standard range on POD5 and 8 in the ELN group, whereas OPF-108 essentially maintained these levels within the standard ranges. Serum iron levels on POD8 were nearly normal in both the OPF-108 and ELN groups. CONCLUSION Beneficial effects of the new micronutrient formulation were demonstrated in surgical patients.

Abstract
Functional gastrointestinal disorders including constipation affect up to 14 % of the world's population. Treatment is difficult and challenging resulting in a need for alternative safe and effective therapies. The present study investigated whether daily consumption of three gold-fleshed kiwifruit could alleviate constipation and improve gastrointestinal discomfort in mildly constipated individuals with and without pain. A total of thirty-two participants were enrolled in a 16-week randomised, single-blind, crossover study. Participants received either three 'Zesy002' kiwifruit or 14·75 g Metamucil® (5 g dietary fibre/d (a positive control)) for 4 weeks each with a 4-week washout between treatments. A 2-week washout period was included at the beginning and end of the study. Daily bowel habit diaries were kept throughout the study. The primary outcome measure was differences in the number of complete spontaneous bowel movements (CSBM). Secondary outcome measures were bowel movement frequency and stool form as well as digestive symptoms and comfort. The number of CSBM per week was significantly greater during daily consumption of three kiwifruit compared with the baseline (6·3 v. 3·3; P < 0·05) and the Metamucil® treatment (6·3 v. 4·5; P < 0·05). Stool consistency was also improved, with kiwifruit producing softer stools and less straining (P < 0·05). Gastrointestinal discomfort was also improved compared with baseline for abdominal pain, constipation and indigestion (P < 0·05) during the kiwifruit intervention and constipation during the Metamucil® intervention (P < 0·05). This randomised controlled trial demonstrates that daily consumption of three gold-fleshed kiwifruit is associated with a significant increase of two CSBM per week and reduction in gastrointestinal discomfort in mildly constipated adults.

Jalili, M, Vahedi, H, Poustchi, H, Hekmatdoost, A
Clinical nutrition ESPEN. 2019;:50-54
Abstract
BACKGROUND & AIMS Irritable bowel syndrome (IBS) is a common gastrointestinal disorder that is more prevalent in women. Vitamin D deficiency and hormonal disorders are also prevalent in Iranian women, and may influence the severity of clinical outcomes mediated by microinflammation, oxidative stress and intestinal permeability pathways. Our objective was to investigate the effects of co-administration of soy and vitamin D on some inflammatory, antioxidant and gut permeability markers in women with IBS. METHODS In a randomized clinical trial, women (18-75 years of age) were randomly allocated into four groups to receive soy isoflavones (40 mg/day), cholecalciferol (50,000 IU/15 days), both soy isoflavones and cholecalciferol, or placebo for six weeks. The outcomes were plasma inflammatory markers, antioxidant status and fecal protease activity at week 0 and week 6. RESULTS After the intervention, plasma inflammatory markers and fecal protease activity were reduced significantly in all treatment groups compared to the placebo group; however, there was no significant effect on antioxidant status. CONCLUSION This study suggests combined supplementation of soy isoflavones and active vitamin D can improve some biochemical parameters regarding inflammation and intestinal permeability of IBS in women.
