Abstract
BACKGROUND AND AIMS Recommended hypoglycemia treatment in adults with T1D consists of 15 g of rapid absorption carbohydrates. We aimed to evaluate the response to fewer carbohydrates for treating hypoglycemia in patients with T1D on insulin pumps with predictive suspension technology (PLGS). METHODS T1D patients on insulin pumps with PLGS were randomized to receive 10 or 15 g of sucrose per hypoglycemia for two weeks (S10 and S15 groups, respectively) when capillary blood glucose (BG) was <70 mg/dL, with crossover after two weeks. Evolution of capillary BG, active insulin, and suspension time were assessed. RESULTS 59 hypoglycemic episodes were analyzed, 33 in S10 and 26 in S15. Baseline BG in S10 was 54.3 ± 7.7 mg/dL versus 56.9 ± 8.8 in S15 (p = 0,239). Active insulin, present in 85% of the episodes, and PLGS suspension time were similar between groups. BG at 15 min was 77 mg/dL in S10 and 95 mg/dL in S15 (p = 0.0007). In S10, 21% of the episodes required to repeat the treatment after 15 min compared with none on S15, with a RR of 0,79 (95% CI 0.66, 0.940, p = 0,014) for successfully treating the episode. Sensor glucose was significantly different from BG at the moment of the hypoglycemia and control 15 min after treatment. No severe hypoglycemia and no rebound hyperglycemia occurred in neither group. CONCLUSIONS A hypoglycemia treatment protocol with a lower dose of sucrose might be insufficient despite PLGS technology. Our data suggest that standard doses of sucrose should still be recommended.

Abstract
OBJECTIVE This study aimed to uncover the effect of voided urinary volume on small intestine permeability ratios in healthy children. METHODS We assessed small intestine permeability in 155 apparently healthy children, aged 3-5 years old, without any visible symptoms of disease, in a rural, malaria-endemic setting in Nigeria, using a multi-sugar test solution, comprising lactulose, sucrose, mannitol, and rhamnose. Children were categorized into low urinary volume (LV) and high urinary volume (HV), based on the volume of urine voided per kg body weight per hour. LV children voided less than 25th percentile of the total population, while HV children voided greater than 75th percentile of the total population. Urinary volume excreted over a 90-minute period after administration of the test solution was measured, and differences in sugar ratios were compared between children with high (HV) and low urinary volumes (LV), as well as between children who voided (VC) or who were not able to void (NVC) before administration of the test solution. RESULTS Urinary mannitol and rhamnose recovery were 44% (p = 0.002) and 77% (p<0.001) higher in HV children compared to LV children respectively, while urinary lactulose recovery was 34% lower (p = 0.071). There was no difference in urinary sucrose recovery between groups (p = 0.74). Lactulose-mannitol ratio, lactulose-rhamnose ratio and sucrose-rhamnose ratio were all significantly higher in children in the LV group compared to children in the HV group (p<0.001). In a multiple regression analysis, urinary volume and voiding status combined, explained 13%, 23% and 7% of the variation observed in lactulose-mannitol, lactulose-rhamnose and sucrose-rhamnose ratios, respectively. CONCLUSION Sugar permeability ratios vary significantly with total urinary volume in multi-sugar small-intestine permeability tests. Voiding status before sugar administration appears to influence lactulose recovery, lactulose-rhamnose and sucrose-rhamnose ratios independently of total urinary volume. Evidence from this study suggests the need to take urinary volume into account when conducting multi-sugar small-intestine permeability tests.

Microvascular research. 2019;:103906
Abstract
BACKGROUND Sugar sweetened beverages (SSB) are a major source of dietary sugar and a public health concern. Glucose consumption acutely influences microvascular reactivity in healthy adults, possibly via oxidative stress. The purpose of this study was to observe the acute influence of a more relevant dose of sucrose on microvascular reactivity, and to identify whether this response is influenced by the amount of vitamin C typically contained in SSB. METHODS Thirteen ostensibly healthy adults (8 male, 5 female) performed three 1-day trials in a randomized order; the consumption of 300 ml water (control; CON), or 300 ml water with 50 g sucrose (SUGAR) or 50 g sucrose with 160 mg of vitamin C (VITC). Near infrared spectroscopy was used to determine peak reactive hyperaemia (PRH), the rate of desaturation (Slope 1) and reperfusion (Slope 2), and the total area under the reperfusion curve versus time (TRH) following 5 min of forearm cuff occlusion before and 30, 60, 90 and 120 min after test drink consumption. RESULTS SUGAR and VITC significantly increased the total area under the curve versus time for plasma glucose (P < 0.05 for both). No changes in microvascular reactivity were observed between trials, although VITC increased Slope 1 compared to both SUGAR and CON 30 and 60 min post drink (P < 0.05 for both). CONCLUSION The consumption of a sugar load representative of commercially available SSB did not influence microvascular reactivity. The co-ingestion of Vitamin C also failed to influence microvascular reactivity, but did increase the rate of oxygen extraction.

Scientific reports. 2018;(1):17824
Abstract
The effect of active acupoints versus inactive acupoints in treating hypertension is not well documented. Metabolic phenotypes, depicted by metabolomics analysis, reflect the influence of external exposures, nutrition, and lifestyle on the integrated system of the human body. Therefore, we utilized high-performance liquid chromatography tandem mass spectrometry to compare the targeted metabolic phenotype changes induced by two different acupoint treatments. The clinical outcomes show that active acupoint treatment significantly lowers 24-hour systolic blood pressure but not diastolic blood pressure, as compared with inactive acupoint treatment. Furthermore, distinctive changes are observed between the metabolomics data of the two groups. Multivariate analysis shows that only in the active acupoint treatment group can the follow-up plasma be clearly separated from the baseline plasma. Moreover, the follow-up plasma of these two groups can be clearly separated, indicating two different post-treatment metabolic phenotypes. Three metabolites, sucrose, cellobiose, and hypoxanthine, are shown to be the most important features of active acupoint treatment. This study demonstrates that metabolomic analysis is a potential tool that can be used to efficiently differentiate the effect of active acupoints from inactive acupoints in treating hypertension. Possible mechanisms are the alternation of hypothalamic microinflammation and the restoration of host-gut microbiota interactions induced by acupuncture.

Abstract
AIM: Repeated, ongoing exposure to pain influences the growth, cognitive and motor functions, behaviour, personality and neurodevelopment of preterm infants. We compared the analgesic effects of expressed breast milk (EBM) and 24% oral sucrose on preterm neonates during venipuncture. METHODS This multicentre randomised, noninferiority, crossover trial focused on five neonatal university units in Madrid, Spain, from October 2013 to October 2014. It comprised 66 preterm infants born at less than 37 weeks and randomly split into two groups. They received either EBM or sucrose two minutes before venepuncture, together with nonnutritive sucking and swaddling, then the opposite procedure at a later point. Pain was measured with the premature infant pain profile (PIPP) and crying was also measured. RESULTS There were no statistically significant differences between the groups. The PIPP scores were seven (4-9) with breast milk and six (4-8.25) with sucrose (p = 0.28). The 11 infants born at under 28 weeks of age showed higher median scores of nine (9-14) for breast milk and four (4-7) for sucrose (p = 0.009). CONCLUSION EBM and 24% sucrose had the same analgesic effect during venipuncture in most of the preterm neonates, but sucrose worked better in extremely preterm infants.

Abstract
BACKGROUND Many patients with chronic kidney disease are prescribed vitamin D receptor agonists (VDRAs) for the management of secondary hyperparathyroidism. Oral phosphate binders may interact with, and potentially reduce the therapeutic activity of, oral VDRAs. This post hoc analysis of a Phase 3 study evaluated the pharmacodynamic effects of the iron-based phosphate binder sucroferric oxyhydroxide (SFOH) and sevelamer (SEV) carbonate on VDRA activity in dialysis patients. METHODS One thousand and fifty nine patients were randomized to SFOH 1.0-3.0 g/day (n = 710) or SEV 2.4-14.4 g/day (n = 349) for up to 52 weeks. Potential interactions of SFOH and SEV with VDRAs were assessed using serum intact parathyroid hormone (iPTH) concentrations as a pharmacodynamic biomarker. Three populations of SFOH- and SEV-treated patients were analyzed: Population 1 (n = 187), patients taking concomitant stable doses of oral VDRAs only; Population 2 (n = 250), patients taking no concomitant VDRAs; Population 3 (n = 68), patients taking concomitant stable doses of intravenous paricalcitol only. Populations were compared using a mixed-effects model to obtain the least squares mean change in iPTH from baseline to Week 52. Differences between treatment groups were also compared. RESULTS In Population 1, iPTH decreased from baseline to Week 52 in the SFOH group (-25.3 pg/ml) but increased in the SEV group (89.8 pg/ml) (p = 0.02). In Population 2, iPTH increased to a similar extent in both treatment groups. In Population 3, iPTH concentrations in both treatment groups decreased to a similar degree (-29.6 and -11.4 pg/ml for SFOH and SEV, respectively; p = 0.87). CONCLUSIONS In contrast with SEV, SFOH did not appear to impact the iPTH-lowering effect of oral VDRAs.

Abstract
BACKGROUND AND OBJECTIVE Increasing data suggest that neonatal pain has long-term consequences. Nonpharmacologic techniques (sucrose taste, pacifier suckling, breastfeeding) are effective and now widely used to combat minor neonatal pain. This study examined the analgesic effect of sucrose combined with radiant warmth compared with the taste of sucrose alone during a painful procedure in healthy full-term newborns. METHODS A randomized, controlled trial included 29 healthy, full-term newborns born at the University of Chicago Hospital. Both groups of infants were given 1.0 mL of 25% sucrose solution 2 minutes before the vaccination, and 1 group additionally was given radiant warmth from an infant warmer before the vaccination. We assessed pain by comparing differences in cry, grimace, heart rate variability (ie, respiratory sinus arrhythmia), and heart rate between the groups. RESULTS The sucrose plus warmer group cried and grimaced for 50% less time after the vaccination than the sucrose alone group (P < .05, respectively). The sucrose plus warmer group had lower heart rate and heart rate variability (ie, respiratory sinus arrhythmia) responses compared with the sucrose alone group (P < .01), reflecting a greater ability to physiologically regulate in response to the painful vaccination. CONCLUSIONS The combination of sucrose and radiant warmth is an effective analgesic in newborns and reduces pain better than sucrose alone. The ready availability of this practical nonpharmacologic technique has the potential to reduce the burden of newborn pain.

Caries research. 2015;(1):18-25
Abstract
OBJECTIVE To examine pH in the approximal dental biofilm after acid and alkali formation from sucrose and urea, after an adaptation period to these substances, in caries-free (CF) and caries-active (CA) individuals. Saliva flow and buffer capacity, and aciduric bacteria in saliva and plaque were also examined. MATERIAL AND METHODS Twenty adolescents and young adults (15-21 years) with no caries (n = 10, D(m + i)MFS = 0) or ≥1 new manifest lesions/year (n = 10, DmMFS = 3.4 ± 1.8) participated. After plaque sampling, interproximal plaque pH was measured using the strip method before (baseline) and up to 30 min (final pH) after random distribution of a 1-min rinse with 10 ml of 10% sucrose or 0.25% urea. This procedure was repeated after a 1-week adaptation period of rinsing 5 times/day with 10 ml of the selected solution. After a 2-week washout period the second solution was similarly tested. Mutans streptococci, lactobacilli and pH 5.2-tolerant bacteria were analyzed by culturing. RESULTS In the CF group, acid adaptation resulted in lowering of baseline and final plaque pH values after a sugar challenge, and in increased numbers of bacteria growing at pH 5.2, which was increased also after alkali adaptation. In the CA group, the final pH was decreased after acid adaptation. No clear effects of alkali adaptation were seen in this group. CONCLUSION One-week daily rinses with sucrose and urea had the most pronounced effect on the CF group, resulting in increased plaque acidogenicity from the sugar rinses and increased number of acid-tolerant plaque bacteria from both rinses.

Lipids in health and disease. 2014;:195
Abstract
BACKGROUND Recent studies have demonstrated a relationship between fructose consumption and risk of developing metabolic syndrome. Mechanisms by which dietary fructose mediates metabolic changes are poorly understood. This study compared the effects of fructose, glucose and sucrose consumption on post-postprandial lipemia and low grade inflammation measured as hs-CRP. METHODS This was a randomized, single blinded, cross-over trial involving healthy subjects (n=14). After an overnight fast, participants were given one of 3 different isocaloric drinks, containing 50 g of either fructose or glucose or sucrose dissolved in water. Blood samples were collected at baseline, 30, 60 and 120 minutes post intervention for the analysis of blood lipids, glucose, insulin and high sensitivity C-reactive protein (hs-CRP). RESULTS Glucose and sucrose supplementation initially resulted in a significant increase in glucose and insulin levels compared to fructose supplementation and returned to near baseline values within 2 hours. Change in plasma cholesterol, LDL and HDL-cholesterol (measured as area under curve, AUC) was significantly higher when participants consumed fructose compared with glucose or sucrose (P<0.05). AUC for plasma triglyceride levels however remained unchanged regardless of the dietary intervention. Change in AUC for hs-CRP was also significantly higher in subjects consuming fructose compared with those consuming glucose (P<0.05), but not sucrose (P=0.07). CONCLUSION This study demonstrates that fructose as a sole source of energy modulates plasma lipids and hsCRP levels in healthy individuals. The significance of increase in HDL-cholesterol with a concurrent increase in LDL-cholesterol and elevated hs-CRP levels remains to be delineated when considering health effects of feeding fructose-rich diets.

Abstract
AIMS: The effect of dietary sucrose on insulin resistance and the pathogenesis of diabetes and vascular disease is unclear. We assessed the effect of 5% versus 15% sucrose intakes as part of a weight maintaining, eucaloric diet in overweight/obese subjects. METHODS Thirteen subjects took part in a randomised controlled crossover study (M:F 9:4, median age 46 years, range 37-56 years, BMI 31.7±0.9 kg/m(2)). Subjects completed two 6 week dietary periods separated by 4 week washout. Diets were designed to have identical macronutrient profile. Insulin action was assessed using a two-step hyperinsulinaemic euglycaemic clamp; glucose tolerance, vascular compliance, body composition and lipid profiles were also assessed. RESULTS There was no change in weight or body composition between diets. There was no difference in peripheral glucose utilization or suppression of endogenous glucose production. Fasting glucose was significantly lower after the 5% diet. There was no demonstrated effect on lipid profiles, blood pressure or vascular compliance. CONCLUSION A low-sucrose diet had no beneficial effect on insulin resistance as measured by the euglycaemic glucose clamp. However, reductions in fasting glucose, one hour insulin and insulin area under the curve with the low sucrose diet on glucose tolerance testing may indicate a beneficial effect and further work is required to determine if this is the case.
