Introduction The acute hospital is a challenging place for a person with dementia whose ability to communicate discomfort and need is impaired. Their discomfort may go unnoticed due to insufficient staffing and time resources in this acute environment. Concerns have been raised about the consequences of these overlooked discomfort (e.g. distress and agitation), and hence how we can correctly identify their sources and severity. This study aimed to describe the source of discomfort and challenging behaviours in people with dementia (PwD) in UK acute hospital. Method A cross-sectional observational study of 49 patients with dementia admitted to a NHS acute hospital. Their discomfort was detected and its sources were identified (Sources of Discomfort Scale) during an hour observation when they were at rest and moved by staff. Their challenging behaviours were also recorded (Neuropsychiatric Inventory) through interviewing with the ward staff, as well as documentation of severity of dementia and presence of delirium. Results The overall prevalence of discomfort was 98%, with excessively sleepy or tired being the commonest; 39 (80%) participants experienced three or more type of discomfort. The commonest sources of discomfort were physical (e.g. constipation) and environmental (e.g. physically restrained), affecting up to 43 (88%) and 42 (83%) participants respectively. There was also evidence of an association between delirium and sleepiness or tiredness’s discomfort, meaning that PwD with delirium were nearly triply as likely to feel uncomfortable because of sleepiness or tiredness. Challenging behaviours affected over 80% of our participants, with agitation or aggression being the commonest. On average, these behaviours were moderately severe. Conclusion Discomfort and challenging behaviours were very common in PwD admitted to acute hospitals. Patients and staff would benefit from more accurate and frequent detection of discomfort by focusing on non-pain-related discomfort and using observational scales.

Background Cancer remains as one of the major causes of mortality worldwide. Recent advances in nanoparticles based therapy mark a new era on cancer treatment. Many groups have investigated biological/physical effects of nanoparticles on tumour cells and how these vary with physical parameters such as particle size, shape, concentration and distribution. Magnetic hyperthermia (MHT) can be an alternative or an add-value therapy with demonstrated effectiveness. MHT uses magnetic nanoparticles, which can be directly applied to the tumour, where, by applying an external ac magnetic field, will promote a localized temperature increment that can be controlled. Methods LiFe5O8 nanocrystallites were synthesized by a novel and eco-friendly sol-gel process, using powder coconut water (PCW) has a mediated reaction medium. The dried powders were heat-treated between 400 and 1000 °C, being analysed their structure, morphology and magnetic properties; cytotoxicity and magnetic hyperthermia assays were performed. Results The heat-treated LiFe5O8 powder led to crystallite sizes from 50 nm to 200 nm. Increasing the temperature of the heat treatment, secondary phases tend to disappear. The cytotoxicity results revealed a non-cytotoxicity property, for concentrations below 5 mg/mL. The sample HT at 1000 °C, revealed hysteresis and magnetic saturation of 73 emu.g−1 at 300 K and a specific absorption rate(SAR) of about 80 W/g. Conclusions It was possible to synthesize LiFe5O8 by a novel, eco-friendly and sustainable route. The nanoparticles have a high heat efficiency, especially the sample heat-treated at 1000 °C, with SAR values similar to Fe3O4, showing potential to be used in the treatment of cancer, by MHT.

Background Informal care is undoubtedly a vital to dementia care in Ireland. To date, little research has been carried out exploring the burden experienced by informal carers of people with mild to moderate dementia. The main aim of this quantitative study is to explore the burden experienced by caregivers, relative to dementia severity. The secondary aim is to identify risk factors which may be contributing to this perceived burden. Methods Fifty-two people with dementia(PwD) and their informal caregivers were recruited by convenience sampling, and data was collected as part of the ‘CHESS’ research trial. Data was collected during baseline assessments between April 2017 and September 2018. Dementia disease severity was measured using the Mini-Mental State Examination(MMSE), the Neuro-Psychiatric Inventory Questionnaire(NPI-Q), and the Disability Assessment for Dementia(DAD) scale. These outcome measures were then compared to levels of caregiver burden, which was measured using the Zarit-Burden Interview(ZBI). These comparisons were completed using Spearman’s correlations. Socio-demographic characteristics of both the carer and PwD were then compared to caregiver burden, using Mann-Whitney and Kruskal-Wallis tests. Results The results of the study substantiate that behavioural disturbances(p=0.000) and increasing disability(p=0.022) of the PwD are associated with higher carer burden. The study also identified potential non-modifiable risk factors for increased carer burden. These include spousal relationship to the PwD(p=0.096), older caregiver age(p=0.208), female carer gender(p=0.083) and higher educational attainment of the caregiver(p=0.035). Some of these differ from factors influencing burden in other international populations. Conclusion This preliminary analysis is the first study of its kind to be carried out in Ireland. It sheds light on potential predictors and risk factors for carer burden and shows need for future research to be carried out in this area. Such research would help to clarify interventions which could minimise the prevalence of the burden experienced by informal caregivers.

OBJECTIVES: Milk and dairy products are a major component of dietary intake, with milk consumption estimated at 6 billion people globally. Adults are reported to consume two or more portions of dairy daily. Cow's milk is composed of a variety of micro and macro nutrients, which is impacted by a range of factors, including lactation stage, and feeding system (indoor vs. pasture). Application of Metabolomics provides in depth analysis of the metabolite composition of milk. The objective was to examine the impact of lactation on bovine milk metabolite levels. METHODS: Metabolomic analysis of bovine milk powder samples across lactation (N = 18), was performed using (1)H-NMR. Metabolites were quantified using Chenomx software (7.7). One-way repeated measures of analysis variance (ANOVA) with Tukeys post hoc test, was preformed on NMR data using SPSS (version 24.0), to assess the impact of lactation stages. P-values were corrected for multiple comparisons using Benjamini and Hochberg false discovery rate (FDR) procedure. Multivariate statistical analysis of the (1)H-NMR data was carried out using SIMCA 13 (SIMCA Version 13.0.3.0 Umetrics, AB). RESULTS: 42 metabolites were identified and quantified in the (1)H-NMR spectra. Statistical analysis revealed that 17 metabolites were significantly different across lactation stages (FDR

OBJECTIVES: To investigate the effects of 12-week daily consumption of wild blueberry (poly)phenols on cognitive performance, vascular function, cerebral blood flow and gut microbiome in healthy older individuals. METHODS: A parallel, double blind, placebo controlled RCT was conducted in 61 healthy individuals, aged 65–80 years. The impact of wild blueberry (poly)phenols on cognition, vascular function (flow-mediated dilation; FMD, and blood pressure; BP), active and resting cerebral blood flow (CBF; using transcranial doppler ultrasound) was assessed. Measurements were taken at baseline and 12-weeks following daily consumption of 26 g freeze-dried blueberry powder containing 260 mg anthocyanins (equivalent to 178 g fresh wild blueberries) or a placebo powder matched for colour, taste, nutrients and fibre. Faecal samples were collected in both visits to measure changes in the gut microbiome using 16s rRNA sequencing. Blood and 24 h urine samples were also collected for the analysis of plasma and urinary (poly)phenol metabolites using LC-MS and authentic standards. RESULTS: Linear mixed modelling analysis with baseline performance as a covariate, revealed that accuracy scores for the switching task targeting executive function, significantly improved for the wild blueberry (WBB) group compared to placebo at 12 weeks (F(1,90,12) = 5.13, P = 0.026)). Additionally, immediate recall measure (AVLT) examining short-term recall memory revealed a significant improvement for the WBB compared to placebo at 12 weeks (F(1,46) = 4.321, P = 0.043)). FMD improved by 0.86% (F(1,54) = 32.8, P

Background and Aims Recent findings suggest that acute kidney injury (AKI), which occurs frequently but is believed to be completely reversible, is an important factor driving chronic kidney disease (CKD) pathogenesis or progression. We have investigated Astragalus membranaceus (AM), which has been shown to have various pharmacological effects on several organs (see http://nccih.nih.gov/health/astragalus). However, up to now, little evidence of its effectiveness against CKD has been provided. We hypothesized that AM could target AKI and that sustainable prevention of AKI by AM might delay pathogenesis and progression of CKD. Here we focused on AKI as a promoter of CKD progression in order to examine the effects of AM histologically and histochemically in mice. Method Here we used two groups of female C57BL/6 mice: one that was aged 12 weeks and one that was aged 52 weeks. After the first blood collection (of approximately 0.2 ml), the two age groups of mice were administered AM powder mixed with sterilized 0.5% methylcellulose 400 (w/v) (the AM-administered group) or sterilized 0.5% methylcellulose 400 (the control group), respectively. Two hours after the administration, 0.5 mg/ml cisplatin (20 mg/kg or 14 mg/kg) or 0.9% NaCl were injected intraperitoneally. Three days after injection, blood was collected and kidneys were harvested. We measured blood urea nitrogen (BUN) and creatinine (CRE) to detect AKI, and assessed histological change in dissected kidney sections stained with Hematoxylin-Eosin and Periodic acid-Schiff and histochemical change in sections stained with anti-CD3 and anti-CD68 antibodies. Generally, 20 mg/kg cisplatin was used to induce AKI in the experimental model. Results Injection with 20 mg/kg cisplatin was shown to induce AKI pathology in young mice and shorten survival in old mice, and AM administration was unable to improve AKI pathology in young mice or survival in old mice. Next, we injected mice in both age groups with 14 mg/kg cisplatin. We found that this dose significantly increased serum BUN or CRE and caused histological damage in renal tubule epithelial cells and glomeruli in old mice but not in young mice, which showed no pathological change. And Astragalus treatment in advance almost totally prevented these pathological changes in old mice. The AKI generated in old mice with 14 mg/kg of cisplatin was significantly normalized by pretreatment with AM. Next, histochemical analysis of renal CD3- and CD68-positive cells revealed both were increased in the murine AKI model induced by injection with 20 mg/kg cisplatin. Interestingly, in old mice, 14 mg/kg cisplatin-AKI increased CD3-positive cells but not CD68-positive cells. These findings suggest that AM may improve daily minor disturbances, such as AKI, that cause pathogenesis and progression of CKD especially in old age. Conclusion AM administration, at least in part, can reduce day-to-day AKI occurrence, but is ineffective in young kidneys. However, sustained use of AM could play a critical role in prolonging the activity of aged kidneys.

Background Nitroglycerin (GTN) results in improved CCTA image quality and diagnostic accuracy due to vasodilation and improved contrast density. Although studies have shown that sublingual (SL) GTN spray has greater vasodilation and faster onset and duration of action compared to SL tablet, it is not commonly used due to cost. The comparative efficacy of SL GTN powder in CCTA is unknown. Purpose The purpose of this study is to determine whether SL GTN powder can increase the coronary lumen volume (V) and the coronary lumen volume to left myocardial mass ratio (V/M) compared to SL GTN tablet. Methods 34 patients (17 females) with 0.8 mg SL GTN powder and 34 patients (17 females) with 0.8 mg SL GTN tablet administration were included in this retrospective case-control study. GTN was given 5 minutes pre-CCTA on a 256 slice single-heartbeat CT. Inclusion criteria: CAD-RADS 0 or 1, precontrast LM + LAD AJ-130 CAC < 100, heart rate less than 75, phase of the cardiac cycle diastole, successful motion correction, Likert score 4 or 5, right- or co-dominance. The primary outcome assessed was left main plus left anterior descending (LM + LAD) V between GTN powder vs tablet. The secondary outcomes were LM + LAD V divided by 1) length of LM + LAD (derived mean area, A), and 2) M (V/M). The outcomes were measured by blinded PI with 17 yrs CCTA experience on GE workstation, 2020 version. Categorical variables were compared by Chi-Squared tests and continuous variables were compared between powder and tablet groups by unpaired t-tests if normally distributed, and Mann-Whitney U tests otherwise. Exploratory outcome analyses tested route of administration by sex interactions and main effects by Two-Way ANOVA’s. Further covariate-adjusted analyses were conducted using multiple linear regression models. Results Baseline characteristics were similar between powder and tablet administration. No statistically significant difference in median V, LM + LAD derived A , or median V/M was observed. A sex main effect demonstrated that females had significantly smaller V (630.6 mm3 vs 951.7 mm3, p< 0.0001) and A (4.2 mm2 vs 6.4 mm2, p< 0.0001) compared to males. These V and A sex differences were also observed when BMI or weight were included as covariates. When V and A were normalized by M, both revealed sex interactions depending on formulation. While males had higher normalized V and A in powder vs tablet (p Conclusions SL administration of the GTN powder 5 minutes before CCTA did not result in greater vasodilatory effect compared to the GTN tablet. However, gender interaction effects were observed, with greater V/M and A/M ratio in males with powder and greater V/M and A/M in women with tablet. These results suggest a potential differential gender effect based on the formulation of GTN. Prospective studies are warranted to evaluate these findings. Abstract Figure.

Background and aims Based on the developed technology of prerparation of ultra small size phospholipid nanoparticles without the use of detergents/surfactants and stabilizers drug preparation, exhibiting hypolipidemic properties has been obtained. Preclinical studies have shown that phospholipid nanoparticles of 20–30 nm (PLN) activate reverse cholesterol transport. PLN is now at the stage of clinical trials (Phase II study completed). The aim of the study was to compare the efficacy, safety and tolerability of PLN relative to placebo in the treatment of combined hyperlipidemia. Methods This Phase III, multicenter, randomized, double-blind, placebo-controlled, parallel-group study was conducted at 4 centers. The patients (pts) received PLN or placebo (1:1), powder for oral solution preparation (in an aqueous environment is a nanoemulsion with a particle size of 20–30 nm), 500 mg (sachet) orally 2 times a day for 12 weeks. Lipid parameters, safety and tolerability were measured. The data is presented in M (s), Me (lq; hq). Mann-Whitney U Test was to compare the significant difference of groups. P value Results A total of 100 pts with combined hyperlipidemia were randomized (age 35–70 years, males 58%).The mean age of patients was 56.4 (10.2) years. Mean total cholesterol, non-high-density lipoprotein cholesterol (non-HDL-C), TG, and apolipoprotein B 100 (apoB) levels at baseline were 5.59 (0.8) mmol/l, 4.51 (0.75) mmol/l, 2.38 (0.6) mmol/l and 114.26 (24.96) mg/dl, respectively (n=100). Mean high-density lipoprotein cholesterol (HDL-C) and Lp(a) levels at baseline were 1.0 (0.25) mmol/l and 21.1 (3.9; 20.3)mg/dl, respectively (n=100). At Week 12, PLT significantly reduced total cholesterol, non-HDL-C levels, TG and apo B compared to placebo (p=0.02, p=0.03, p=0.001 and p=0.02, respectively). At the same time, the mean HDL-C level was significantly increased (p=0.03). The drug was well tolerated and no clinically significant laboratory abnormalities were detected. Conclusions This study demonstrates that therapy with PLT is well tolerated in additional beneficial effects on key lipid parameters in patients with moderate combined hyperlipidemia.

OBJECTIVES: In a time when prolonged sitting is an important part of people's daily busy lives, any easy solution contributing to enhancing general stamina and amateur fitness physical performance in a safe and inexpensive way can be always attractive. Red beetroot (Beta vulgaris rubra) and its constituents known as having important health benefits in many various areas, has become increasingly popular in the arena of exercise performance, mainly due to high concentrations of nitrate. Previous studies done in different types of professional athletes - most of them using beetroot either as juice or powder - proved its clear efficiency in increasing the physical performance both in terms of speed and endurance. Could beetroot help as well other kind of individuals who due to their busy professions, though willing to stay fit, have less access to higher degree of physical activity? The aim of this preliminary study was to evaluate in which measure beetroot can be used by amateurs willing to improve their general stamina and stay physically fit. METHODS: The benefits of plant compounds contained in beetroot - such as betanin, vulgaxanthin and inorganic nitrates - known to help increase the blood oxygenation, muscle strength, and mental acuity - were evaluated among healthy adults (age 25–60) during a short sessions of simple physical activity, repeated for 7–10 days. To compare, a single serving of 100 g raw beetroot was taken 1–2 hours prior the activity and evaluations were made. An intelligent health bracelet was used to measure some of the common vital parameters. RESULTS: Though modest, an average increase in the daily physical performance of 6.17%, a general increase of 31% at the end of the period of evaluation, and most of all, a visible increase in general stamina, shows the great potential beetroot has as ergogenic aid in moderate exercise. CONCLUSIONS: Though raw beetroot may provide modest performance enhancement, the observations show to be encouraging and more research would be definitely needed, in a larger number of individuals, on a more diverse types of physical activities, and using more professional evaluating tools, in order to clarify the mechanism of action and eventually the proper dosing patterns.

OBJECTIVES: The adolescent period is crucial for optimizing future bone health because during these years bone accumulates rapidly accounting for up to half of adult peak bone mass (PBM). Calcium intake during this stage is critical for adequate bone mineralization but this essential nutrient, the major constituent of hydroxyapatite, is usually inadequate in the diets of US adolescents. A strategy to maximize bone mineralization is to increase calcium absorption. This could be achieved by soluble corn fiber (SCF) supplementation, which fermentation through bacteria in the lower intestine produces short-chain fatty acids and increase calcium absorption. However, there are no studies determining the long-term effects of SCF on bone mass in children. The main aim of the MetA-Bone Trial is to determine the effect of one-year SCF supplementation compared to placebo on bone mass in children with low habitual calcium intake. We hypothesize that SCF supplementation will result in a higher Bone Mineral Content. We will also determine the effects of SCF supplementation on bone biomarkers; we hypothesize that supplementation with SCF will result in higher levels of bone formation and lower bone resorption biomarkers. METHODS: A total of 240 healthy children (10–13 years), with usual low dietary calcium, will be randomized to four experimental groups for 1 year: (1) SCF (12 g/d); (2) SCF (12 g/d) + 600 mg/d of calcium; (3) Placebo (maltodextrin); and (4) Placebo + 600 mg/d of calcium. The supplements will be mixed with a flavored powder beverage to dilute in water and participants will be instructed to drink this twice per day. Bone mass will be measured using dual energy x-ray absorptiometry (DXA) at baseline, 6 and 12 months. Serum bone biomarkers will be measured at baseline and at 12 months. RESULTS: NA CONCLUSIONS: If supplementing diets with SCF lead to higher bone mass during adolescence, this could help achieve the genetic potential for PBM and to start adult life with stronger bones. Incorporating SCF into diets may be a cost-effective intervention for bone health than increasing dairy products consumption, particularly in adolescents.

OBJECTIVES: Multiple studies have examined the effects of fresh watermelon, watermelon juice, or watermelon powder on satiety and skin health; however, few studies have addressed the effects of blenderized (flesh, rind, and seeds) watermelon juice. The objective of this study was to determine the effects of blenderized watermelon juice consumption on satiety, postprandial glucose, insulin response, and topical application on skin health in healthy adults. METHODS: In a crossover design, subjects (N = 20, 16 females, 4 males, age 22.8 ± 2.5 y, BMI 22.6 ± 2.80 kg/m(2)) consumed 8 fl oz of either blenderized watermelon juice or isocaloric sugar water. After an overnight fast, blood glucose and insulin levels were measured at baseline, and at 30 and 60 minutes after drink consumption. Measurements for satiety using a visual analogue scale and skin health using a moisture content test were conducted at baseline, right after, 15, 30, 45, and 60 minutes after consumption and topical application of the juices. RESULTS: Both blenderized watermelon and sugar water significantly increased satiety (P

OBJECTIVES: Streptococcus salivarius (S. salivarius) K12 supplementation in children and adults has been found to reduce the risk of recurrent pharyngitis, tonsillitis, otitis media caused by group A streptococci. The protection of S. salivarius K12 supplementation may in part result from its production of lantibiotic bacteriocins salivaricin A and B. Yet, studies have not reported the effect of supplementation on oral S. salivarius K12 levels or the broader salivary microbiome. The objective of this clinical trial was to determine how supplementation with S. salivarius K12 influences the oral microbiome. METHODS: In a double-blind, placebo-control, prospective trial, 24 healthy adults were randomized to consume a probiotic powder (PRO) containing 7.8B CFU of L. acidophilus, 8.25B CFU of B. lactis, and 2B CFU of S. salivarius K12 (n = 12) or a placebo-control powder (CON) (n = 12) for fourteen consecutive days. Saliva samples were collected at baseline, at the end of the fourteen-day supplementation period and two weeks post-supplementation. Oral S. salivarius K12 and total bacteria were quantified by QPCR and the oral microbiome was measured using 16s rRNA amplicon sequencing. RESULTS: Supplementation with S. salivarius K12 significantly increased salivary S. salivarius K12 by 5 logs compared to baseline for the PRO group (P

OBJECTIVES: Multi-ingredient dietary supplements (DSs) containing green tea (GT) were analyzed for their phytochemical content (seven catechins and caffeine) as part of a Dietary Supplement Ingredient Database project. The label information required by FDA is the weight of the GT extract or leaf powder, unless it is part of a proprietary blend (only the blend weight needed). Any information about the concentration of GT phytochemicals is voluntary. We assessed the accuracy of the mandatory and voluntary portions of labels and the effect of proprietary blends on the phytochemical content. METHODS: Two lots of 37 GT DSs, estimated to contain ≥40 mg/serving of GT, were purchased in a variety of market channels. Samples were sent for analysis to two experienced laboratories. Means and standard errors for the analytically measured content of epigallocatechin gallate (EGCG; the most prevalent catechin), the summed content of the catechins (total catechins, TC), and caffeine were derived for each DS and compared to label information. RESULTS: The measured content of EGCG, TC, and caffeine showed wide ranges (0 (not detected) - 442, 0–711, and 0–982 mg/day, respectively). DSs with concentration claims for EGCG and caffeine (32% and 43%, respectively) had higher content per serving compared to DSs without such information (P

OBJECTIVES: Chronic inflammation is an important driver of co-morbidities of obesity. Studies have indicated that cocoa (Theobroma cacao) and cocoa polyphenols can exert anti-inflammatory and anti-obesity properties in animal models. Fermentation and roasting are important for flavor and aroma development of cocoa but have been reported to decrease total phenolic content (TPC). The effect of these processing steps on anti-inflammatory bioactivity has not been examined in vivo. We examined the impact of fermentation and roasting on the anti-obesity and gastrointestinal protective effects of cocoa in high fat diet (HFD)-fed mice. METHODS: Male and female mice were fed HFD for 9 wks to induce obesity and then randomized to receive either HFD or HFD supplemented with one of seven cocoa powders (80 mg/g diet) for an additional 8 wks. The cocoa powders differed in terms of roasting (no roast or 30 min at 120°C or 170°C) and fermentation (no, cool, or hot). Body weights were measured weekly. Following euthanasia, serum and cecal digesta were collected. Visceral fat, liver, and spleen were collected and weighed. Small intestine and colon were collected and measured. Prior to euthanasia, gut permeability was measured in a subset of mice from each group. RESULTS: Mice treated with cocoa-supplemented diets had lower rate of weight gain: final body weights were 9–13% and 5–19% in males and females, respectively. Cocoa treatment also resulted in longer colon lengths (18–26% in males and 11–24% in females) and reduced gut permeability (50–75% lower) compared to HFD-fed controls indicating reduced colonic inflammation. While fermentation and roasting did impact chemistry and bioactivity, the unfermented, unroasted cocoa was not necessarily the most effective, and some combinations resulted in equivalent or improved bioactivity. Cytokine and microbial composition analysis are ongoing. CONCLUSIONS: Our results show that all treatments mitigated weight gain, colon inflammation, and gut permeability induced by HFD. The degree of fermentation and roasting and TPC may not predict efficacy. This indicates that it may be possible to develop processing steps to optimize both cocoa flavor and health-related bioactivity. FUNDING SOURCES: This work was funded by USDA AFRI.

OBJECTIVES: Dietary berries have been shown to lower cardio-metabolic risks in clinical trials. We examined the dose-response effects of two dietary achievable doses of strawberries on low-density lipoprotein cholesterol (LDL-C) and insulin resistance in adults with metabolic syndrome. METHODS: In this 14-week randomized controlled crossover study, adults with metabolic syndrome were assigned to one of the three arms for 4 weeks separated by a one-week washout period: control powder, one serving strawberries (13 g powder/day), and 2.5 servings strawberries (32 g powder/day). The freeze-dried powders were blended in water, and participants consumed half the daily dose in the morning and half in the evening. Participants were instructed to follow their usual diet and lifestyle while refraining from consuming other berries and related products throughout the study. RESULTS: Thirty participants completed all three phases of the trial (baseline profiles: weight: 90.8 ± 22.4 kg, BMI: 33.1 ± 4.2 kg/m(2), waist circumference: 109 ± 12.5 cm, HbA(1c) : 5.8 ± 0.2%). Outcome measures were analyzed using a multivariate analysis of variance with statistical significance set at P

OBJECTIVES: We aimed to develop and validate a tool to estimate vitamin A (VA) intake and identify children at risk of intake above the tolerable upper intake level (UL). METHODS: We developed, pilot-tested, and refined a screening tool to estimate VA intake among Filipino children 12–18 mo of age. Data were entered into tablets with pre-loaded food composition data to calculate VA intake immediately. The screening tool was used to identify children likely to have “adequate” (one group: 200–500 µg retinol activity equivalents, RAE/d) or “high” (two groups: >600 µg retinol/d) intake. Interviewers administered four 24-h recalls, one 12-h observed weighed record with 12-h recall, and a 30-d supplement questionnaire. Breastmilk intake and VA concentration were measured among breastfeeding children. We compared the screening tool and detailed dietary assessment (DDA) results for primary VA sources, group mean usual intake, and prevalence of intakes above the UL. RESULTS: Major VA sources were similar between methods: fortified milk powders, multivitamin supplements, and breastmilk; contributions from intervention programs (e.g., micronutrient powders, fortified staple foods) were low. Mean usual retinol intakes for the high groups (n = 47 and 39, respectively) were 1218 and 1313 µg/d by screening tool vs. 1096 and 931 by DDA; 70 and 77% had usual intake above 600 µg/d. In the adequate group (n = 37), mean total VA intake was 375 and 559 µg RAE/d by screening and DDA, respectively. CONCLUSIONS: This screening tool provides a reasonably good rapid estimate of VA intake among Filipino children and can be useful for identifying groups with adequate to excessive intakes.

OBJECTIVES: US children ages 4 and older use multivitamin/mineral supplements (MVMs) formulated to meet the Daily Values for adults. To better evaluate the potential for nutrient adequacy and excess, it is helpful to determine actual ingredient content instead of amounts declared on labels. We tested children's MVMs and compared the products’ labeled and measured contents with Recommended Dietary Allowances (RDA) and Upper Tolerable Intake Levels (UL) established for children ages 4 to 8 years. METHODS: Children's MVMs were defined as dietary supplements (DSs) containing three or more vitamins with or without minerals and other bioactive components labeled for individuals ages 4 and older. Nationally representative children's MVMs were identified based on relative market share estimates (RMSE) derived from frequency of use and respondents’ weights in infant/pediatric MVM subsets of 2003–2006 National Health and Nutrition Examination Surveys, and store surveys. The 21 top and 43 lower market share DSs selected for this study represented ∼72% of the total RMSE. The DSs were purchased in 2008 from multiple market channels in regions of AL, CA, MI, MO, NY, and OK identified using a multistage probability-proportional-to-size approach. Vitamin and mineral content was measured by commercial labs in 3 to 6 lots of 47 chewable tablets, 11 gummies, 4 liquids, 1 gumball, and 1 powder DS. RESULTS: For 13 of 16 nutrients (copper, iodine, iron, zinc, folic acid, niacin, riboflavin, thiamin, vitamins A, B-12, B-6, D and E), most MVMs were labeled at or above the RDA but below UL levels. For calcium, magnesium and phosphorus, all the studied DSs were labeled below the RDAs. The DSs that contained zinc, niacin and retinol labeled above their ULs had overall mean RMSEs comparable to the DSs labeled within the RDA-UL ranges. Overages resulted in levels exceeding the UL for folic acid in 24 out of 29 DSs labeled at the UL and for retinol in 10 out 40 DSs labeled below the UL, including one of the three most highly consumed MVMs. CONCLUSIONS: The prevalence of children's MVMs on the US market with labeled levels at or above the RDA, or at UL, combined with analytically verified overages, suggests risks of excess in intakes for zinc, niacin, retinol and folic acid, especially when MVM use is combined with diets containing many highly fortified foods.

OBJECTIVES: Self-reporting methods for dietary exposure are error-prone and have had limited impact to identify food components that mitigate disease risk. The purpose of this study was to use non-targeted and targeted metabolomics from feeding trials with rice bran and navy beans for the identification of dietary biomarkers across the lifespan. METHODS: Prepared meals/snacks, and biological samples from randomized-controlled trials performed in 50 infants, 38 children and 49 adults were utilized in this study. Diet groups were placebo control, rice bran, cooked navy bean powder, or a combination of rice bran/navy beans with increasing daily doses by age group and for duration of 4, 12 or 24 weeks per protocol. Plasma/dried blood spots, urine or stool samples were collected at a baseline, midpoint and endpoint. Non-targeted profiling was performed with UPLC-MS/MS, and metabolite quantification by LC-triple-quadropole (LC-QQQ-MS). A linear mixed model to compare between time points in each group was performed using SAS. RESULTS: The plasma/blood metabolomes contained between 771–1001 metabolites and showed variation in ∼20–30% of the profile following intervention. Fold changes over time and fold-differences in metabolite abundance were assessed by age (P

OBJECTIVES: Recent research indicates that the taste quality of fatty acids, called ‘Oleogustus’, differs from the traditionally accepted five basic tastes. However, the actual quality of the sensation has not been characterized. One question is whether there is a sour component because very short-chain fatty acids, like acetic acid, the sour tastant in vinegar, is structurally a fatty acid. The present study investigated the quality sensation of fatty acids of graded chain length. METHODS: Sensory stimuli were acetic acid, butyric acid, hexanoic acid, octanoic acid, decanoic acid, lauric acid, oleic acid, and linoleic acid emulsions and palmitic acid, stearic acid powder. The intensity of the samples before and after expectorating was measured. Next, participants repeatedly sipped, held for 5 seconds, and expectorated a sour solution (0.09% w/w) and rated the intensity on a gLMS until the intensity was lower than “weak”. After adaption to the sour solution, the intensity of the sample was measured before and after expectorating. Participants recorded the quality of each sample. RESULTS: The intensity of acetic acid was significantly lower after adaptation (P

OBJECTIVES: Dementia and cognitive decline are typical age-related neurological disorders. However, obesity has been linked to premature senescence manifestations in various systems including the central nervous system. Nutritional interventions play a role in curbing obesity-associated disorders. Epidemiological studies suggest that increased consumption of fruits and vegetables (F&V) is associated with a reduced risk of cognitive impairment and dementia. The objective of this study was to investigate the causal role of F&V consumption in prevention of high fat diet-induced cognitive impairment in mice. METHODS: Freeze-dried powder of a mixture of 24 F&V was added into the animal diets. Male C57BL/6 J mice (6 wk) were randomly assigned to one of the three diet groups (12/group): low fat (LF, 10% kcal fat), high fat (HF, 45% kcal fat), and HF plus 15% F&V (HF + F&V). The novel object recognition test was used to evaluate cognitive function at 17 weeks. After 20 weeks, mice were euthanized. Blood and liver were collected and biochemical variables and gene expression levels were determined. Fecal microbiota was characterized by 16S rRNA sequencing. RESULTS: Compared to the LF group, mice fed the HF diet for 17 weeks had significant cognitive impairment. F&V supplementation significantly reduced the HF diet-induced cognitive impairment. Further, compared to mice fed the LF diet, those fed the HF diet had significantly higher levels of liver lipid peroxides (measured as MDA), and circulating pro-inflammatory cytokines and sphingolipid ceramides, all of which are known to contribute to neuroinflammation and cognitive deficits. These HF diet-induced adverse effects were significantly reduced in mice fed the HF + F&V diet. In addition, F&V supplementation alleviated HF diet-induced gut dysbiosis and greatly reduced abundance of some of the bacteria associated with inflammation. CONCLUSIONS: This study provides evidence for the causal role of F&V intake in preventing high fat diet-induced cognition impairment in mice. The beneficial effects of F&V supplementation in improving cognitive function might be due to F&V-induced changes in gut dysbiosis, inflammatory cytokines, and ceramides.

OBJECTIVES: “Bignay” (Antidesma bunius), “lipote” (Syzygium polycephaloides) and “duhat” (Syzgium cumini) are indigenous berries in the Philippines that are known to contain high antioxidant properties and other health-promoting and disease-preventing compounds. However, oral toxicity studies on these berries are not yet explored. Hence, this study evaluated the acute oral toxicity of these berries in freeze-dried forms using 6-week old ICR mice following the OECD guidelines 425 (up and down method). METHODS: Treatment groups were administered with freeze-dried powders of “bignay”, “lipote” and “duhat” reconstituted in distilled water at various doses: 55 mg/kg body weight (BW), 175 mg/kg BW, 550 mg/kg BW, 2000 mg/kg BW and 5000 mg/kg BW while control group was administered with distilled water. Body weight, feed and water intake were obtained daily. Biochemical profiles were measured prior to administration of reconstituted berries at day 1 and prior to euthanasia. Toxicity, morbidity and mortality cases were observed daily. Euthanasia and necropsy were performed to check for gross organ abnormalities. RESULTS: Mice that received the different concentrations of “bignay”, “lipote” and “duhat” had normal feed and water consumption and gained weight during the test period. No clinical and behavioral signs of toxicity were observed and there was zero morbidity and mortality. Post-mortem evaluation showed no lesions on various organs examined. Blood ALT, BUN and creatinine levels were within normal published values. CONCLUSIONS: These results show that different concentrations of freeze-dried “bignay”, “lipote” and “duhat” are non-toxic using ICR mice and therefore have high potential to be developed into food supplements and nutraceuticals.

OBJECTIVES: Chardonnay grape marc is the remaining skins and seeds after pressing and is a byproduct of winemaking that offers a rich source of phytonutrients. The objective was to evaluate postprandial lipid response following adding Chardonnay grape marc powder to the diet. METHODS: Overweight or obese men and women with hyperlipidemia between 35–65 y were recruited for this randomized, double-blinded 16-week crossover study. Subjects consumed 1500 mg of 1) placebo, 2) high Chardonnay seed extract, low Chardonnay marc blend (HE) or 3) high chardonnay marc, low chardonnay seed extract blend (HM) in a randomized order. Each intervention arm lasted 3 weeks and included two 3-week washout periods. Following each intervention, fasting blood was drawn, then subjects consumed a high fat challenge meal. Postprandial blood was subsequently drawn at 1, 2 and 3 hours. Incremental area under the curve (iAUC) was also calculated. Data were not normally distributed thus were log transformed before conducting analyses. Analyses were conducted with 24 completed subjects and intention to treat for 3 subjects who withdrew using linear mixed model ANOVA. RESULTS: Incremental area under the triglyceride curve response to a meal showed a significant effect of intervention (P = 0.05). Pairwise comparisons showed a significant difference between HE and HM (P = 0.04). CONCLUSIONS: Following HM intervention, there was a significantly lower triglyceride iAUC compared to the HE intervention, but no difference compared to placebo. HM intervention resulted in better triglyceride clearance compared to the HE intervention. FUNDING SOURCES: NIFA Phase II Small Business Innovation Research Grant awarded to Sonomaceuticals, LLC.

OBJECTIVES: Improved formulations of complementary foods (CFs) with animal-source foods (ASFs) is an eminent strategy to improve infant nutrition, but they are expensive and not readily available in many food insecure settings which are a haven of edible insects. Hence, we developed orange-fleshed sweet potato (OFSP) based CFs supplemented with Cricket or palm weevil larvae (PWL), examined its nutritional content and microbial quality for infant feeding. METHODS: OFSP roots were sourced from local farmers, peeled, sliced, steam cooked and mechanically dried into OFSP flour. Cricket powder and PWL paste were obtained from commercial producers, steam cooked, and mechanically dried into Cricket/PWL flours. OFSP flour was mixed with either Cricket/PWL flours in the ratios of 100:0 (control), 85:15, 70:30, and 50:50 and used to produce ready-to-eat CFs. The CFs were evaluated for nutrient composition and microbial contamination using standard methods. ANOVA followed by Dunnett's test was used to compare all the formulations to the control. RESULTS: There were increase in protein (4.80 to 36.75%), iron (1.26 to 4.38 mg/100 g), zinc (0.69 to 10.65 mg/100 g) and calcium (45.54 to 152.77 mg/100 g) contents of the OFSP-based CFs with increased supplementation with Cricket/PWL flour. The carbohydrate and β-carotene content decreased but the energy content increased with increased supplementation with cricket/PWL flour from 344.52 Kcal/100 g in 100% OFSP CF to 541.09 Kcal/100 g in 50:50 CFs (OFSP: PWL) (P = 0.001). Aerobic mesophilic count (AMC) of the OFSP: Cricket CFs was 60 cfu/g as compared to 1300 cfu/g for the OFSP: PWL CFs. Comparing the OFSP-based Cricket/PWL CFs to the commercial Cricket or PWL, there was 35–331-fold reduction in AMC. Bacillus cereus (BC), aerobic (APC) and anaerobic plate count (NPC) was 0 cfu/g for the OFSP: Cricket CFs. BC, APC and NPC were 100, 260 and 130 cfu/g respectively for the OFSP: PWL CFs. CONCLUSIONS: Steam cooking, then mechanical drying significantly reduced microbial concentrations in commercial Cricket and PWL to below minimum limits set by the Ghana Standards Authority for CFs requiring heating to boiling before consumption. OFSP-based Cricket/PWL composite flours could be safe viable alternatives as nutritious CFs in countries where they are culturally accepted as food.

Background Diabetes is a huge problem affecting 387 million adults by a global prevalence of (8.3%) which is expected to rise to (10.1%) affecting 592 million adults by 2035. Type 2 diabetes, a growing public health problem, is associated with increased morbidity and mortality. Purpose To evaluate the effects of ginger powder supplementation on glycemic status, lipid profile, insulin resistance, insulin sensitivity, and beta-cell function in obese Egyptian patients with new-onset type 2 Diabetes Mellitus. Patients and Methods This study was conducted at the Diabetes outpatient clinic of the National Institute of Diabetes and Endocrinology (NIDE) during the period from January 2016 to January 2017. Study Design A randomized, single blind, placebo-controlled clinical trial, was performed on 80 subjects newly diagnosed with T2DM. Subjects were randomly & equally subdivided into two groups: Group 1: Ginger Group (GG), which consumed three capsules daily, each capsule containing: 600-mg of ginger powder (total daily dose was 1.8 g), they also underwent certain diet and physical activity changes, and also received metformin as one 850-mg tablet twice a day with meals for a duration of 8 weeks.Group 2: Placebo Group (PG), which received capsules of the same color, size, and number as (Group 1) but containing wheat flour, they also underwent the same diet, physical activity, and metformin dosage as (Group 1) during the 8 weeks of the study. Results Ginger powder supplementation significantly reduced body mass index, fasting blood glucose, 2-hour postprandial blood glucose, glycated hemoglobin, total cholesterol, low density lipoprotein cholesterol, triglycerides, fasting insulin levels, and homeostasis model assessment-insulin resistance index (HOMA2-IR). Ginger also significantly increased high density lipoprotein cholesterol levels, beta cell function index (HOMA2-%β), and insulin sensitivity index (HOMA2-%S). Conclusion Ginger is considered a safe and effective adjuvant antidiabetic agent in treatment of T2DM; improving glycemic status, lipid profile, insulin resistance, and promoting weight loss.

Preservation of cheese microbiota biodiversity is central to the sensory quality of traditional and PDO cheeses. Lyophilized commercial selected starters, being advantageous in terms of cells concentration, are supplanting natural cultures causing important loss of microbial biodiversity in the dairy environment. Biodiversity could be recovered using natural starter cultures, however their cells concentration after propagation is lower than the commercial ones. Two autochthonous and biodiverse starter cultures (MixA and MixB) coming from scotta (residual whey from Ricotta cheese manufacture), collected in the 1960 s from Pecorino Romano PDO cheese manufactures, were revitalized in reconstituted commercial powder scotta. The aim of this study was the propagation of the microbial starter mixes increasing their bacterial concentration in the pellet, reducing nonessential scotta components by a fast and not-expensive method, without changing the microbial community balance. The behaviour of each mix inoculated in scotta was compared to that in half-concentrated, clarified, and half-concentrated-clarified scotta. Higher cells concentration in the pellets from the modified scotta was obtained, without changing technological performances and microbial fingerprint. The pellets obtained were reinoculated in commercial scotta for the preparation of the scotta-innesto (the typical starter for Pecorino Romano), and no differences were observed among the treatments after incubation. The reduction of nonessential scotta's components could help the reproduction of natural starter cultures preserving their properties.

TiO2 is broadly used in a wide range of applications such as photocatalysis, pigments and additives. Despite the promising commercial opportunities, different studies have shown that TiO2 can induce oxidative stress, inflammatory and genotoxic effects. The European Union has classified certain titanium dioxide powders and powder mixtures containing TiO2 as a suspected carcinogen (Category 2) via inhalation. Considering that the information about the potential adverse health effects of TiO2 in occupational environment are still scarce and controversial, the purpose of the study was to investigate the genotoxic effects and oxidative stress in workers exposed to TiO2 during paint production. Biomarkers of early effect (DNA damage and micronuclei) were evaluated in the buccal cells and salivary leucocytes of 30 workers (15 production workers and 15 controls). To collect information about personal details, occupational history, medication, smoking, diet, physical activity, a questionnaire was administered to all workers. Personal and area monitoring have been carried out to determine airborne inhalable and respirable fraction of TiO2; a NanoTracer was used to monitor the presence of ultrafine particles. In spite of the low mass concentration and a mild percentage of nanoparticles, filter deposited TiO2 was in sub-micron size, thus accounting for its respirability. Preliminary results on salivary leucocytes show a slight higher DNA damage in the exposed workers as compared to the controls. Whereas biomarker assessment is still in progress, these preliminary findings show that workers are exposed to low but measurable levels of TiO2 able to induce a mild genotoxic damage. A combined approach using both personal exposure assessment and biomonitoring can improve the risk assessment in occupational settings in which TiO2 is handled. Moreover, this also suggest to take precautionary measure during specific activities and operational phases thus decreasing the risks for worker. Key messages The results of the present study may promote effective risk management practices in occupational environments that uses TiO2. The results obtained suggest the introduction of activities and operational phases with lower risks for the worker.

Background The synthetic opioid methadone is utilized in pain management and opioid addiction therapy. Patients with methadone prescriptions are monitored for compliance using immunoassay-based urine drug screens (UDS) for methadone and its primary metabolite, 2-ethylidene-1,5-dimethyl-3,3-diphenylpyrrolidine (EDDP). It is well documented that immunoassays are subject to false positive results due to cross-reactivity of antibody reagents with structurally related and unrelated compounds. A 30-year-old male with a history of polysubstance abuse presented to the emergency department with altered mental status and was noted to have a positive UDS for EDDP. Reflex mass spectrometry testing was negative for both methadone and EDDP. Upon improvement, the patient endorsed use of powder derived from the tropical plant Kratom, whose main components, mitragynine and 7-hydroxymitragynine, function as opioid receptor agonists. Kratom use has become popularized in the United states in spite of warnings by the United States Food and Drug Administration about its potential to cause addiction, abuse, and dependence. Here we describe our investigation of Kratom as a positive interferent in the Thermo Scientific CEDIA Methadone Metabolite (EDDP) immunoassay. Methods Patient specimens that underwent urine drug screens as part of routine clinical care at the University of Virginia Health System over 3 non-contiguous months meeting the following criteria were included in the study: EDDP screen ≥10 arbitrary absorbance units, negative methadone screen, and negative methadone or EDDP mass spectrometry confirmation (if available). Urine drug screens were performed on the Olympus AU480 Chemistry Analyzer using the Thermo Scientific CEDIA Methadone Metabolite (EDDP) immunoassay and the Siemens Syva Emit II Plus Methadone assay. Specimens were tested for mitragynine, 7-hydroxymitragynine, methadone and EDDP using the Sciex X500R QTOF with Sciex Exion Liquid Chromatography. Results A total of 48 specimens met the inclusion criteria, where 50% (24/48) confirmed positive for mitragynine and/or 7-hydroxymitragynine and negative for methadone/ EDDP. Methadone and/or EDDP was detected in 33% (16/48), none of which confirmed positive for mitragynine or 7-hydroxymitragynine and 17% were negative for all four analytes. Urine spiked with a methanol extract prepared from Kratom powder produced no signal in the EDDP screen. Spiking drug-free urine with 10,000 ng/mL mitragynine and 10,000 ng/mL 7-hydroxymitragynine both resulted in indeterminate EDDP screens. Since several drugs are glucuronidated during phase II metabolism we performed enzymatic hydrolysis on urine specimens and rescreened the specimens using the EDDP immunoassay. Upon hydrolysis, mitragynine and/or 7-hydroxymitragynine positive specimens showed a significantly higher percent increase in absorbance on the EDDP screen compared to those in which methadone and/or EDDP was detected (p=0.0031). Conclusion Our studies suggest that a Kratom metabolite can cause false positive results in the Thermo Scientific CEDIA Methadone Metabolite (EDDP) immunoassay. Kratom use should be investigated in cases of false positive urine drug screens for EDDP.

Background While the majority of pediatric osteomyelitis cases are acute in nature, a significant subset present with prolonged symptoms often associated with substantial morbidity. Little data exist to guide clinicians in the management of these infections. We sought to describe the epidemiology, clinical features and management of chronic osteomyelitis in children. Methods We reviewed hospital admissions with an ICD10 code for chronic osteomyelitis from 2011-2018 at Texas Children’s Hospital. Cases were included if symptoms lasted >28 days on presentation. Patients diagnosed with chronic recurrent multifocal osteomyelitis were excluded. Cases were classified as those 1) associated with a contiguous focus (CoF), 2) penetrating or open trauma, 3) orthopedic hardware (OH), 4) post-acute chronic osteomyelitis (PACO, those occurring after >28 days of therapy for acute osteomyelitis) and 5) primary hematogenous chronic osteomyelitis (PHCO, those with 28 days of symptoms without other clear risk factors). Results 114 cases met inclusion criteria. The median patient age is 11.8 years and 35.9% patients had underlying comorbidities. 83% of patients underwent a surgical procedure. Cases were diverse in terms of pathogenesis (Figure 1). A microbiologic etiology was identified in 72.8% of cases and was polymicrobial in 20.2% of cases; Staphylococcus aureus was the single most common etiology (Figure 2). CoF infection was more often associated with polymicrobial etiology with or without Pseudomonas (P< 0.001) and disease of the foot. PACO was caused by S. aureus in 95% of cases (p< 0.001, Figure 3). The overall median duration of total therapy was 210 days. 41% were discharged from hospital on OPAT with or without later transition to oral antibiotics. 26.3% of patients had persistent functional limitations at time of last follow-up of which 46% experienced repeat hospital admission/surgery. There was no association between duration of intravenous therapy and persistent functional limitations. Figure 1. Categories of Chronic Osteomyelitis Figure 2. Microbiology of Pediatric Chronic Osteomyelitis Figure 3. Clinical Features of Pediatric Chronic Osteomyelitis Conclusion Children with chronic osteomyelitis are diverse both in terms of pathogenesis and microbiology. Pathogenesis and clinical presentation can provide clues to microbiologic etiology.

Introduction In large skin injuries, lack of matrix deposition impedes timely healing process. The longer a wound remains open, the greater is the risk of infection, non-healing, and other complications. It is therefore crucial to find effective means to promote rapid closure of skin defects. Our group has previously developed a liquid in situ-forming nutritional scaffold, known as MeshFill (MF). MF has been previously proven to be very effective in accelerating the wound repair process, notably that of complex wounds. However, MF is limited in its application to deep and tunnelling wounds, and requires reconstitution with a solvent as well as maintenance at cold temperature until application. To address these limitations, our group has developed a powdered form of MF for rapid topical application on superficial skin injuries such as dehisced surgical wounds and burn injuries. Methods Our goal was to investigate whether a powdered form of MF could be directly applied onto the wounds to accelerate healing. Ideally, powdered MF would absorb the moisture within the wound environment and reconstitute into the gel form in situ. We examined the efficacy of powder MF (PMF) compared to reconstituted gel MF (GMF) and to a standard dressing protocol. To do so, splinted full thickness wounds were generated on the back of mice and treated with either PMF or GMF or were bandaged with no treatment (NT). The healing process was monitored until wounds were fully closed. Clinical wound measurements and histological assessments were performed to compare different treatment regimens. Results Application of both PMF and GMF accelerated wound epithelialization at days 7 and 14, compared to NT, and had faster wound closure times. On average, the PMF treatments healed 17% faster than the NT control, and the GMF treatments healed 21% faster than the NT control. No significant difference between PMF and GMF was found for any outcomes. Additionally, our results suggest that epidermis formation was more effective in P and MF conditions compared to NT. Conclusions These findings suggest that topical application of a powdered form of MeshFill is as effective as standard reconstituted MeshFill gel in accelerating the healing process of skin injuries. Applicability of Research to Practice Topical application of a powdered scaffold may be a very convenient and practical method for rapid treatment of large superficial wounds such as dehisced surgical wounds, burn injuries, and filling gaps in meshed skin grafts.

OBJECTIVES: The study investigated the effects of blueberry consumption on biomarkers of glycemic control in US veterans with type 2 diabetes. METHODS: In a double-blind, placebo-controlled parallel study, fifty-five men (mean baseline characteristics: 67 years; weight, 103 kg; body mass index, 34 kg/m(2)) with type 2 diabetes were randomly assigned to 1 of 2 treatment groups for 8 weeks. The treatment groups were either 22 g of a freeze-dried whole blueberry powder (equivalent to 1 cup of fresh blueberries; containing 845 mg phenolics and 470 mg anthocyanins) or 22 g of a blueberry placebo treatment (matched in energy and carbohydrate content to the blueberry treatment). The study participants were asked to consume 11 g of freeze-dried (equivalent to ½ cup of fresh blueberries) blueberry powder or placebo, reconstituted with 240 ml water, with their morning and evening meals along with their typical diet. Fasting blood samples were collected at the beginning and at the end of the study. RESULTS: Fructosamine (275.5 ± 4.1 µmol/L vs. 292.4 ± 7.9 µmol/L, respectively; P = 0.04) and hemoglobin A1C (7.1 ± 0.1% vs. 7.5 ± 0.2%, respectively; P = 0.03) were significantly lower for study participants consuming blueberries for 8 weeks compared with the placebo. In addition, triglycerides (160.6 ± 13.1 mg/dl vs. 183.9 ± 10.7 mg/dl, respectively; P = 0.03), aspartate transaminase (AST) (23.2 ± 1.4 units/L vs. 30.5 ± 2.7 units/L, respectively; P = 0.02) and alanine transaminase (ALT) (35.6 ± 1.5 units/L vs. 48.3 ± 2.9 units/L, respectively; P = 0.0003), were significantly lower for those consuming blueberries compared with the placebo. Glucose, insulin, total cholesterol, LDL cholesterol, HDL cholesterol and body weight were not significantly different after 8 weeks of consumption of blueberries compared with the placebo. CONCLUSIONS: Consumption of 22 g of freeze-dried blueberries daily for 8 weeks results in better glycemic control, such as lowering of fructosamine and hemoglobin A1C. These results along with lower triglyceride concentrations show improvement in the liver enzymes, AST and ALT, which may beneficially affect the cardiometabolic health status of men with type 2 diabetes.

OBJECTIVES: To examine whether diet supplementation with blackberry or raspberry attenuate angiotensin (Ang) II-induced increase in blood pressure (BP) and decrease oxidative stress in the kidneys of mice. METHODS: Twelve-week male C57BL/6 J mice were fed AIN-93 M diets alone (control and Ang II groups) or supplemented with 10% w/w freeze-dried blackberry (BL + Ang II) or raspberry (RB + Ang II) powder for eight weeks. At week 4, mice were implanted with subcutaneous osmotic minipumps that delivered 0.9% saline (Control) or Ang II (1 µg/kg body weight/day) for another four weeks. BP was measured weekly by tail-cuff plethysmography and validated by direct measurement at endpoint using a BP catheter. Kidney expression of pro-oxidant enzymes such as NADPH oxidases (Nox) and antioxidant enzymes such as superoxide dismutates (SOD) were also measured. Results were analyzed using ANOVA followed by Tukey-Kramer post-hoc test. RESULTS: As expected, Ang II significantly increased systolic BP (SBP; 185 ± 4, n = 6, vs 132 ± 2 mmHg, n = 5, P

OBJECTIVES: We evaluated the impact of an integrated infant and young child feeding (IYCF) – micronutrient powder intervention on IYCF practices among caregivers of children 12–23 mo in Eastern Uganda. METHODS: We used pre-/post- data from two population-based, cross-sectional surveys representative of children aged 12–23 mo in Amuria (intervention) and Soroti (non-intervention) districts. Caregivers were interviewed in June/July at baseline 2015 (N = 1260) and 12 mo after implementation in 2016 (N = 1490) about their IYCF practices the day preceding the survey. Logistic regression estimated the double-difference effect of the intervention on core World Health Organization (WHO) IYCF indicators: child ever breastfed, current breastfeeding, bottle feeding, complementary foods introduced at age 6 mo, consumption of vitamin A-rich fruits or vegetables, consumption of animal-flesh foods, minimum meal frequency (MMF) (received food ≥3 times for breastfed children and ≥4 times for non-breastfed children), minimum dietary diversity (MDD) (received foods from ≥4 of 7 WHO food groups), and minimum acceptable diet (MAD) (MDD and MMF among breastfed children, and ≥2 milk feeds, MDD not including milk feeds, and MMF among non-breastfed children). Analyses were weighted and accounted for complex sampling design. RESULTS: After controlling for child age and sex, household wealth, household food security, and caregiver education, the intervention was positively associated with MMF (Adjusted Prevalence Difference-in-Difference [APDiD] 18.6%; 95% Confidence Interval [CI] 11.2, 26.0) and MAD (APDiD 5.6%; 95% CI 0.02, 11.2). The intervention was associated with 21.8% higher prevalence of timely introduction of complementary feeding (95% CI 13.4, 30.1) and with increased consumption of both vitamin A-rich fruits/vegetables (APDiD 23.5%; 95% CI 12.5, 34.5) and animal-flesh foods (APDiD 9.1%; 95% CI 1.5, 16.7). The intervention did not affect breastfeeding or bottle feeding practices. Despite program impact, prevalence of some IYCF practices were low in Amuria at endline including MAD (19%) and MMF (21%). CONCLUSIONS: The integrated IYCF intervention had a positive impact on many core WHO IYCF practices; however, low endline prevalence of some indicators suggests a continued need to improve complementary feeding practices in Eastern Uganda.

OBJECTIVES: This study evaluated the nutrients (proximate, vitamins, minerals) and sensory attributes of some products; fried plantain buns (FPB), baked plantain buns (BPB) and steamed plantain buns (SPB) made from over-ripped plantain. METHODS: A bunch of matured over-ripe plantain samples (3.2 kg) were collected, washed with deionised water, peeled, mashed into pulp. About 400 g plantain pulp were mixed with other ingredients (egg 2 medium size, baking powder (14 g), vanilla flavor (0.5 ml) and onions (13 g) ), fried, steamed and baked respectively. Nutrient composition analysis was carried out in the Food Chemistry Laboratory, University of Nigeria, Nsukka, Enugu State, Nigeria. Sensory evaluations of the three products developed were done in the Food Diet Laboratory using nine-point Hedonic scale with twenty four (24) panellists. Data obtained were subjected to statistical analysis using analysis of variance (ANOVA), Standard deviation and Fisher least significance difference (FLSD) were used to compare the mean at P 0.05), the highest moisture content (56.52%) was found in steamed plantain buns. The mineral content shows that Ca, Mg, Fe and Zn levels were comparable (P > 0.05) in all the samples while potassium content ranged from 342.7 to 312.0 mg/100 g with the highest level in SPB. Generally FPB has the highest mineral contents compare with BPB and SPB. Vitamin content in all the samples showed that vitamin C, vitamin A and vitamin E were present. However, there was no significant (P > 0.05) difference among the products. The general acceptability of FPB, BPB and SPB in terms of color, flavor, taste and texture were very high (8.12, 7.12 & 6.71) respectively. Although FPB and BPB were most preferred, SPB was accepted sparingly. CONCLUSIONS: In conclusion, senescence plantain losses may be reduced if the over ripped ones are converted to buns products and this will consequently add to the value chain and also minimize economic loss globally.

OBJECTIVES: Epidemiological studies have shown that consumption of fruits and vegetables (F&V) is inversely associated with incidence of cardiovascular disease (CVD). However, the evidence for causality and underlying mechanisms is lacking. Our objective was to determine if increased consumption of F&V could prevent atherosclerosis and its underlying mechanisms. METHODS: A unique blend of the most commonly consumed 24 F&V was freeze-dried into a powder and mixed into diets. Thirty six 4-week old male LDL receptor knockout mice were randomly assigned to one of 3 diet groups (12/group): low fat (LF, 10 kcal% fat), high-fat (27 kcal% fat) with 0% F&V (HF), and HF plus 15% F&V diet (HF + FV, equivalent to 8–9 servings for humans). After 20 weeks, mice were euthanized and blood, aorta, and liver tissue were collected. Aortic atherosclerotic lesion, hepatic steatosis, plasma lipid profile and pro-inflammatory cytokine levels were measured. RESULTS: No significant differences were found in body weight among the 3 groups. Mice fed HF diet had larger aortic atherosclerotic lesion and hepatic steatosis area than mice fed LF diet by 6.5 and 1.9 fold, respectively (p

OBJECTIVES: To examine whether daily incorporation of 40 grams of whole blueberry into the diets of postmenopausal women with mild to moderate degree of bone loss will positively influence indices of bone metabolism. METHODS: In a randomized, double-blind control trial, 40 postmenopausal women with mild to moderate degree of bone loss, not on hormone or other bone therapies, were randomized to either consume 40 g of lyophilized blueberry powder (LBP) (n = 20) or a placebo powder (n = 20) daily for 90 days. Plasma bone biomarkers including sclerostin, bone-specific alkaline phosphatase (B-ALP), receptor activator of nuclear factor kappa-Β ligand (RANKL), tartrate-resistant acid phosphatase (TRAP5) and inflammatory marker, interleukin(IL)-6 was assessed at baseline, mid-point (45 days) and final (90 days). Bone density and body composition was assessed at baseline and final visits only. Fracture risk assessment tool (FRAX) was utilized to determine major osteoporotic fracture risk. RESULTS: A total of 32 participants completed the study with an attrition rate of 20%. A significant increase of B-ALP was observed at mid-point in the blueberry treatment group, indicating increased bone formation, however the increase was not maintained at final point. In addition, a more pronounced decline in RANKL was observed at final point in the LBP group as compared to the placebo group. A slight decline in the probability of a major osteoporotic fracture was observed in the LBP group, while an increase of such risks was observed in the placebo group. Moreover, in the placebo group, a significant increase in IL-6 was observed at final point, but the LBP group maintained their IL-6 throughout the study with a declining trend from baseline to final point. Besides bone metabolism parameters, body weight was decreased significantly in the blueberry group at final point, along with a more pronounced decrease in %body fat as compared to the placebo group. No changes in bone densities were observed, possibly due to the short study duration. CONCLUSIONS: The findings of the study suggest that blueberry consumption may have nominal protective effects on bone in postmenopausal women who have mild to moderate bone loss. A longer study duration may more favorably influence bone metabolism and bone density in this population.

OBJECTIVES: Approximately 1.4 million people suffer from inflammatory bowel disease, which is a major risk factor for developing colitis associated colorectal cancer (CAC). Dietary interventions with the goal to reduce colon inflammation and encourage gut microbiome homeostasis may be a strategy to reduce the risk of CAC. The antioxidants and anti-inflammatory compounds present in black raspberries (BRB) have demonstrated protective effects in the colon epithelium and may alter the composition of the gut microbiome. Previously, we showed that dietary supplementation with black raspberries significantly suppressed colitis and colon tumorigenesis promoted by the consumption of a Western type diet in mice. The goal of this study was to compare the efficacy of dietary intervention with whole, freeze-dried black raspberries on colitis and colon tumorigenesis in mice consuming either a standard diet or a Western type diet that emulates typical U.S. nutrient intakes. METHODS: C57BL/6 J male and female mice were fed a standard diet (AIN93G) or the total Western diet (TWD) supplemented with 0 to 10% (w/w) black raspberry powder for a total of 16 weeks. All mice were dosed with axozymethane and provided 1% dextran sodium sulfate in drinking water for 10 days to promote colonic inflammation and tumorigenesis. RESULTS: As previously observed, mice fed TWD experienced more pronounced symptoms of colitis with a 40% increase in the disease activity index (DAI) score. Preliminary analyses suggest that dietary supplementation with 10% BRB suppressed the DAI score in mice fed TWD such that the colitis symptoms in these mice were not apparently different compared to the AIN93G-fed controls. However, addition of 10% BRB did not appear to provide a benefit to mice fed the AIN basal diet. Composition of the fecal microbiome over the course of disease development will be determined by standard 16S rRNA sequencing, and assessment of tumor outcome is ongoing. CONCLUSIONS: Consumption of a Western type diet increased symptoms of colitis, whereas dietary supplementation with 10% BRB appeared to ameliorate TWD-enhanced colitis in mice.

OBJECTIVES: In low and middle-income countries, early child development (ECD) is associated with stunting, but the association with length-for-age z-scores (LAZ) is understudied. The objective is to examine whether the association with ECD among infants extends beyond stunting to LAZ and whether it is altered by nurturance or inflammation. METHODS: Sample: 513 infants (mean age 8.6 months, SD 2.2), 20% stunted (LAZ 1 SD, LAZ was not related to ECD (Figure 1). CRP was not related to ECD and CRP interaction was not significant. CONCLUSIONS: The positive association between LAZ and ECD illustrates vulnerability prior to the threshold of stunting. Maternal nurturance is positively associated with multiple domains of infants’ ECD and attenuates relations between LAZ and receptive language and fine motor. Inflammation (measured by CRP) is not associated with ECD. Linear growth within normal and nurturant caregiving are needed to promote ECD.

OBJECTIVES: Development of a probiotic P. acidilactici NRRL B-50517 that resists to high temperature (up to 85°C), stomach acids, and air. Clinic evaluation of P. acidilactici NRRL B-50517 as a safe probiotic for regulation of weight related pro-inflammatory cytokines. METHODS: Survival studies were conducted by incubating P. acidilactici NRRL B-50517 in either liquid MRS broth, pH1.5 at 85°C overnight, or in dried powder at 85°C for 5–10 minutes. Healthy volunters were randomly assigned two capsules of placebo or Pediococcus probiotics (4 billion CFU) daily for three months. Biweekly phone interviews with 30 participants were performed to ensure daily dosage administration, and to collect the results of the questionnaire related to 6 categories of gut functions. Percent body fat measurements and serum were collected upon study initiation and completion. Serum was processed for cytokine analysis by multiplex ELISA assays. RESULTS: P. acidilactici NRRL B-50,517 survived at 85°C and pH 1.5 in MRS broth and dried powder forms. No statistical significantly changes of gut functions between the placebo group and the probiotic group in appetite: t-value 1.6808, p-value 0.1313; energy level: t-value 0.7508. p-value 0.5003; bowel movement: t-value 0.3348. p-value 0.7464; stool quality: t-value 0.6929, p-value 0.5080; bloating: t-value 2.0583. p-value 0.0736; gas t-value: 1.9560, p-value 0.0875. On average, the probiotic lost 0.86% ± 0.42% body fat whereas the control group gained 0.28% ± 0.19, P = 0.0264. Pro-inflammaroty IL-6 ratios differed by 0.61 ± 0.22 and 3.06 ± 0.87 in the probiotic and control groups, respectively (P = 0.0295); pro-inflammatory IL23 ratio was 0.65 ± 0.14 in the probiotic and 1.71 ± 0.38 in the control group, P = 0.0068. CONCLUSIONS: Novel P. acidilactici NRRL B-50,517 is safe for human consumption and may be useful in reducing body fat and pro-inflammatory markers. FUNDING SOURCES: TEDCO, Maryland.

Heat-stable antifungal factor (HSAF), which was first isolated from Lysobacter enzymogenes, exhibits inhibitory activities against a wide range of pathogens; however, a low level of HSAF was obtained from L. enzymogenes cultured in 0.1 × tryptic soy broth (TSB), an amount that does not satisfy HSAF application in disease control. In this study, the optimization of media components and environmental conditions were examined for improving the production of HSAF from L. enzymogenes OH11. The one factor at a time method was used to screen optimal nitrogen and carbon sources and inorganic salt. Then the orthogonal matrix method was used to determine the optimal concentration of the media components and environmental factors. The results showed that the maximum level of HSAF (23361 mAU·s) was achieved when OH11 cultured in the media of 0.7% (w/v) soybean powder, 0.5% (w/v) glucose and 0.08% CaCl2 at 200 rpm at 30°C for 60 h, which is much higher than that cultured in 0.1 × TSB. This opens up the possibility of HSAF or L. enzymogenes utilization for biological control of plant disease.

OBJECTIVES: This study aims to determine in vitro the effect of collagen size on anti-aging activity in the form of anti-glycation, tyrosinase inhibitors and antioxidant activity in order to obtain the optimum anti-aging collagen isolation technique from sea grape cereal with the addition of tempe. METHODS: Sample preparation by making cereals consisting of sea grape and tempe flour into powder using a Freeze Dryer (Lyovapor ™ L-200). Collagen isolation was carried out by varying the concentration of NaOH, which are 0.10 M; 0.20 M; and 0.30 M with a ratio of 1:10 (w/v) for 48 hours, followed by immersion using 1 M acetic acid with a ratio of 1:10 (w/v) for 24 hours. Collagen obtained from the best immersion treatment with NaOH solution is dissolved in distilled water with a ratio of 1 : 2 (v/v) and the size is changed with the help of a magnetic stirrer at a speed of 1000 rpm with a time variation of 5 and 10 hours. The results were then tested for particle size using a Particle Size Analyzer (PSA) and then tested for antioxidant activity using the DPPH (2,2-diphenyl-1-picrylhydrazyl) method, anti-glycation, and tyrosinase inhibitors. Selection of the best results is based on antioxidant, anti-glycation, and anti-tyrosinase activities. The data obtained from three replications were analyzed using ANOVA at a 95% confidence interval. RESULTS: Collagen isolated with 0.10 M NaOH was the collagen with the largest particle size, yield and anti-glycation respectively 2.45 µm, 11.65%, 62.76% and had the infrared spectrum that best matched the standard collagen. Furthermore, this collagen is stirred at a speed of 1000 rpm for 5 and 10 hours for size reduction. Collagen with 5 hours stirring has a smaller particle size (1482 nm) compared to 10 hours stirring (1568 nm). Collagen with a size of 1482 nm showed the best activity, namely antioxidant activity against (DPPH) of 24.70% and tyrosinase inhibitor of 26.77%. There was a significant difference (P

OBJECTIVES: The objective of this study was to predict the intervention scenarios that best fulfil the nutrient adequacy in Filipino complementary diets in rural settings using linear programming (LP) analyses of special fortified foods, alone or in combination with complementary feeding recommendations (CFRs). METHODS: A cross-sectional survey was conducted in the municipality of Mercedes, Camarines Norte Province. Dietary intakes of breastfed children 6–8, 9–11 and 12–23 months of age (n = 297) were assessed using a multi-pass 24-hour recall method with 7-day food consumption frequency. Optifood, an LP tool was used to formulate age-specific CFRs and determine the extent to which special fortified foods, namely micronutrient powder (MNP), small-quantity lipid-based nutrient supplements (LNS-SQ) and fortified blended food with micronutrient powder (FBF + MNP), can contribute towards nutrient adequacy in complementary diets. RESULTS: LP analyses show that for 6–8 and 9–11-month-old infants, requirements for iron will be difficult to meet even with four serves of MNP per week, while for 9–11 and 12–23-month-old young children, calcium adequacy would remain a challenge even with daily serves of LNS-SQ per week. Adequacy for 11 modelled micronutrients could only be achieved if CFRs that modify current dietary patterns were fully adopted along with supplementation of LNS-SQ 5–7 times per week. CONCLUSIONS: Adoption of food-based CFRs with special fortified products is necessary to best fulfil the gaps of essential micronutrients in the diets of rural Filipino children aged 6–23 months. The findings provide insight into the current program in the Philippines. The MNP supplementation with the usual ration of MNP 3 to 4 times per week would not be sufficient to ensure adequacy for iron in 6–8 and 9–11-month-old infants unless the frequency is increased to 5 times per week. Empirical intervention studies are needed to confirm the LP simulations and feasibility of the CFRs. FUNDING SOURCES: The authors received no funding for this work.

OBJECTIVES: Micronutrients, especially iron, play a critical role in the developing infant brain. Yet, the causal effects of iron supplementation on neurocognitive functioning in a low-income anemic population of children have not been examined. This study sought to evaluate the effects of supplementation with iron syrup and iron-containing multiple micronutrient powders (MNPs) in Bangladeshi children on habituation to familiar sounds, a marker for healthy memory development, using auditory event-related brain potentials (ERPs). METHODS: This study was nested within the Benefits and Risks of Iron Supplementation in Children (BRISC) trial, a double blinded double dummy randomized controlled trial (RCT). At 8 months of age, 3300 children were randomized to receive 3 months of 1) iron syrup + placebo MNPs, or 2) MNPs (containing iron, retinol, zinc, and Vitamin C) + placebo iron syrup, or 3) placebo iron syrup and placebo MNPs. ERPs in response to an auditory roving oddball paradigm were measured in a random subset of 441 children at 3 months post-intervention (11 months of age) and 595 children after a further 9 months follow-up (20 months of age). ERP measures indexing aspects of habituation included the [deviant minus standard] difference waveform amplitude, N2 waveform amplitude, and the difference in deviant-evoked ERP amplitudes between the first and second half of the paradigm. Intention-to-treat analyses on ERP outcomes using linear models were used at 11 and 20 months of age separately. RESULTS: Baseline characteristics were balanced between treatment groups. Overall prevalence of anemia was 43.7% and iron deficiency was 28.4%. Intention-to-treat analyses indicated no significant treatment effects of iron or MNPs on the difference waveform amplitude at 11 months of age [mean difference (MD, 95% CI) iron vs placebo 0.24 (–1.03, 1.51); MNP vs placebo 0.59 (–0.70, 1.88)] and 20 months of age [(MD, 95% CI) iron vs placebo 0.50 (–0.62, 1.63); MNP vs placebo 0.24 (–0.89, 1.38)]. There were no differences by treatment arm for the other ERP measures. CONCLUSIONS: Results from a rigorous prospectively powered sub-study of an RCT in an iron deficient population indicated no significant effects of supplementation with iron or MNPs on neural indices of habituation.

Item does not contain fulltext OBJECTIVES: The shiny vestibular surfaces of teeth make it difficult to match digital dental casts to 3D stereophotogrammetric images of patient teeth. This study tested whether reducing this shininess by coating the teeth with titanium-oxide powder might improve the accuracy of the matching procedure. METHODS: Twenty patients participated in the study. For each patient, 3D stereophotogrammetric images were taken without and with a powder coating. Separately, digital dental casts were created. Next, the digital dental casts were fused with the 3D stereophotogrammetric images of either non-powdered or powdered dentition. Distance maps were created to evaluate the inter-surface distance between the digital dental cast and the 3D images. The matching accuracy was compared for dentition with and without powdering. RESULTS: Of all recorded distances between corresponding points, 95% was smaller than 0.84mm for the powdered dentition and smaller than 0.90mm for the non-powdered dentition. Although powdered dentition showed significantly better matching than non-powdered dentition, the difference was less than 0.1mm. Intra-observer statistics showed that five out of 24 repetitions gave significantly different results, but only for dentition that was not powdered. LIMITATIONS: The patients did not have any major malocclusions. Severe malocclusions might cause greater difficulty in matching the dentition without powder. Only one type of powder was used, but it effectively reduced shininess. CONCLUSION: Powdering the dentition had a small, but significant, positive effect on matching. However, this effect was of minor clinical importance. Therefore, we do not recommend powdering the dentition for 3D stereophotogrammetric images used for matching procedures.
