    We investigated the quality characteristics and antioxidant activities of yogurt supplemented with 1%, 2%, and 3% aronia juice and fermented for 24 h at 37°C. The total acidity increased with increasing levels of aronia juice and incubation time. Lightness and yellowness of the yogurt decreased, but redness increased, with increasing aronia juice content and incubation time. The number of lactic acid bacteria (LAB) increased with increased incubation time, and yogurt containing 2% and 3% aronia juice showed higher LAB counts than 1% aroinia juice-supplemented yogurt. The total polyphenol and flavonoid contents increased proportionally with increasing levels of aronia juice. Antioxidant activity of aronia-containing yogurt was significantly higher than that of the control and increased proportionally with aronia juice concentration. Yogurt with 2% aronia juice had the best taste (P<0.05). Aronia juice may be a useful additive for improving the taste and antioxidant potential of yogurt. PMID:28078255

    Full Text Available Abstract Background Two economic factors make watermelon worthy of consideration as a feedstock for ethanol biofuel production. First, about 20% of each annual watermelon crop is left in the field because of surface blemishes or because they are misshapen; currently these are lost to growers as a source of revenue. Second, the neutraceutical value of lycopene and L-citrulline obtained from watermelon is at a threshold whereby watermelon could serve as starting material to extract and manufacture these products. Processing of watermelons to produce lycopene and L-citrulline, yields a waste stream of watermelon juice at the rate of over 500 L/t of watermelons. Since watermelon juice contains 7 to 10% (w/v directly fermentable sugars and 15 to 35 μmol/ml of free amino acids, its potential as feedstock, diluent, and nitrogen supplement was investigated in fermentations to produce bioethanol. Results Complete watermelon juice and that which did not contain the chromoplasts (lycopene, but did contain free amino acids, were readily fermentable as the sole feedstock or as diluent, feedstock supplement, and nitrogen supplement to granulated sugar or molasses. A minimum level of ~400 mg N/L (~15 μmol/ml amino nitrogen in watermelon juice was required to achieve maximal fermentation rates when it was employed as the sole nitrogen source for the fermentation. Fermentation at pH 5 produced the highest rate of fermentation for the yeast system that was employed. Utilizing watermelon juice as diluent, supplemental feedstock, and nitrogen source for fermentation of processed sugar or molasses allowed complete fermentation of up to 25% (w/v sugar concentration at pH 3 (0.41 to 0.46 g ethanol per g sugar or up to 35% (w/v sugar concentration at pH 5 with a conversion to 0.36 to 0.41 g ethanol per g sugar. Conclusion Although watermelon juice would have to be concentrated 2.5- to 3-fold to serve as the sole feedstock for ethanol biofuel production, the results

    Full Text Available Dietary supplementation with pomegranate juice improves isometric strength recovery after unaccustomed eccentric exercise. The purpose of this study was to determine if there is a dose response effect of pomegranate juice supplementation after eccentric exercise isometric strength recovery. Forty-five nonresistance trained, recreationally active men were assigned once-daily pomegranate juice, twice-daily pomegranate juice, or placebo supplementation. On day four of supplementation, 20 min of downhill running and 40 maximal eccentric elbow flexion repetitions were performed. Isometric knee extensor and elbow flexor strength, muscular soreness, and serum myoglobin concentrations were measured prior to exercise and 2, 24, 48, 72, and 96 h after exercise. Throughout the postexercise time period, while isometric knee extensor and elbow flexor strength were similar between once-daily and twice-daily pomegranate juice supplementation groups, isometric strength was significantly higher in pomegranate juice groups than placebo. Knee extensor soreness, elbow flexor soreness, and myoglobin increased in response to exercise but were similar between groups. It is apparent that pomegranate juice supplementation improves strength recovery in leg and arm muscles following eccentric exercise; however, no dose response effect was present. We conclude that once-daily pomegranate juice supplementation is not different from twice-daily supplementation in regards to strength recovery after eccentric exercise.

    Athletes use nutritional supplementation to enhance the effects of training and achieve improvements in their athletic performance. Beetroot juice increases levels of nitric oxide (NO), which serves multiple functions related to increased blood flow, gas exchange, mitochondrial biogenesis and efficiency, and strengthening of muscle contraction. These biomarker improvements indicate that supplementation with beetroot juice could have ergogenic effects on cardiorespiratory endurance that would benefit athletic performance. The aim of this literature review was to determine the effects of beetroot juice supplementation and the combination of beetroot juice with other supplements on cardiorespiratory endurance in athletes. A keyword search of DialNet, MedLine, PubMed, Scopus and Web of Science databases covered publications from 2010 to 2016. After excluding reviews/meta-analyses, animal studies, inaccessible full-text, and studies that did not supplement with beetroot juice and adequately assess cardiorespiratory endurance, 23 articles were selected for analysis. The available results suggest that supplementation with beetroot juice can improve cardiorespiratory endurance in athletes by increasing efficiency, which improves performance at various distances, increases time to exhaustion at submaximal intensities, and may improve the cardiorespiratory performance at anaerobic threshold intensities and maximum oxygen uptake (VO2max). Although the literature shows contradictory data, the findings of other studies lead us to hypothesize that supplementing with beetroot juice could mitigate the ergolytic effects of hypoxia on cardiorespiratory endurance in athletes. It cannot be stated that the combination of beetroot juice with other supplements has a positive or negative effect on cardiorespiratory endurance, but it is possible that the effects of supplementation with beetroot juice can be undermined by interaction with other supplements such as caffeine.

    Full Text Available The beneficial effects of beetroot juice supplementation (BJS have been tested during cycling, walking, and running. The purpose of the present study was to investigate whether BJS can also improve performance in swimmers. Fourteen moderately trained male master swimmers were recruited and underwent two incremental swimming tests randomly assigned in a pool during which workload, oxygen uptake (VO2, carbon dioxide production (VCO2, pulmonary ventilation (VE, and aerobic energy cost (AEC of swimming were measured. One was a control swimming test (CSW and the other a swimming test after six days of BJS (0.5l/day organic beetroot juice containing about 5.5 mmol of NO3−. Results show that workload at anaerobic threshold was significantly increased by BJS as compared to the CSW test (6.3 ± 1 and 6.7 ± 1.1 kg during the CSW and the BJS test respectively. Moreover, AEC was significantly reduced during the BJS test (1.9 ± 0.5 during the SW test vs. 1.7 ± 0.3 kcal·kg−1·h−1 during the BJS test. The other variables lacked a statistically significant effect with BJS. The present investigation provides evidence that BJS positively affects performance of swimmers as it reduces the AEC and increases the workload at anaerobic threshold.

    In the last years, several studies have recently evaluated the beneficial effects of red orange juice (Citrus sinensis (L.) Osbeck) and its active components in weight management and obesity. Moro orange is a cultivar of red orange, particularly rich in active compounds such as anthocyanins, hydroxycinnamic acids, flavone glycosides and ascorbic acid, which displays anti-obesity effects in in vitro and in vivo studies. In this clinical study, the effect of a Moro juice extract (Morosil(®), 400 mg/die) supplementation was evaluated in overweight healthy human volunteers for 12 weeks. Results showed that Moro juice extract intake was able to induce a significant reduction in body mass index (BMI) after 4 weeks of treatment (p juice have a synergistic effect on fat accumulation in humans and Moro juice extract can be used in weight management and in the prevention of human obesity.

    Full Text Available The aim of this study was to test the hypothesis that pomegranate juice supplementation would blunt acute and delayed oxidative stress responses after a weightlifting training session. Nine elite weightlifters (21.0 ± 1 years performed two Olympic-Weightlifting sessions after ingesting either the placebo or pomegranate juice supplements. Venous blood samples were collected at rest and 3 min and 48 h after each session. Compared to the placebo condition, pomegranate juice supplementation attenuated the increase in malondialdehyde (−12.5%; p < 0.01 and enhanced the enzymatic (+8.6% for catalase and +6.8% for glutathione peroxidase; p < 0.05 and non-enzymatic (+12.6% for uric acid and +5.7% for total bilirubin; p < 0.01 antioxidant responses shortly (3 min after completion of the training session. Additionally, during the 48 h recovery period, pomegranate juice supplementation accelerated (p < 0.05 the recovery kinetics of the malondialdehyde (5.6% and the enzymatic antioxidant defenses compared to the placebo condition (9 to 10%. In conclusion, supplementation with pomegranate juice has the potential to attenuate oxidative stress by enhancing antioxidant responses assessed acutely and up to 48 h following an intensive weightlifting training session. Therefore, elite weightlifters might benefit from blunted oxidative stress responses following intensive weightlifting sessions, which could have implications for recovery between training sessions.

    This study aimed to improve the fermentation efficiency of Kloeckera africana K1, in tequila fermentations. We investigated organic and inorganic nitrogen source requirements in continuous K. africana fermentations fed with Agave tequilana juice. The addition of a mixture of 20 amino-acids greatly improved the fermentation efficiency of this yeast, increasing the consumption of reducing sugars and production of ethanol, compared with fermentations supplemented with ammonium sulfate. The preference of K. africana for each of the 20 amino-acids was further determined in batch fermentations and we found that asparagine supplementation increased K. africana biomass production, reducing sugar consumption and ethanol production (by 30, 36.7 and 45%, respectively) over fermentations supplemented with ammonium sulfate. Therefore, asparagine appears to overcome K. africana nutritional limitation in Agave juice. Surprisingly, K. africana produced a high concentration of ethanol. This contrasts to poor ethanol productivities reported for other non-Saccharomyces yeasts indicating a relatively high ethanol tolerance for the K. africana K1 strain. Kloeckera spp. strains are known to synthesize a wide variety of volatile compounds and we have shown that amino-acid supplements influenced the synthesis by K. africana of important metabolites involved in the bouquet of tequila. The findings of this study have revealed important nutritional limitations of non-Saccharomyces yeasts fermenting Agave tequilana juice, and have highlighted the potential of K. africana in tequila production processes.

    Both caffeine and beetroot juice have ergogenic effects on endurance cycling performance. We investigated whether there is an additive effect of these supplements on the performance of a cycling time trial (TT) simulating the 2012 London Olympic Games course. Twelve male and 12 female competitive cyclists each completed 4 experimental trials in a double-blind Latin square design. Trials were undertaken with a caffeinated gum (CAFF) (3 mg·kg(-1) body mass (BM), 40 min prior to the TT), concentrated beetroot juice supplementation (BJ) (8.4 mmol of nitrate (NO3(-)), 2 h prior to the TT), caffeine plus beetroot juice (CAFF+BJ), or a control (CONT). Subjects completed the TT (females: 29.35 km; males: 43.83 km) on a laboratory cycle ergometer under conditions of best practice nutrition: following a carbohydrate-rich pre-event meal, with the ingestion of a carbohydrate-electrolyte drink and regular oral carbohydrate contact during the TT. Compared with CONT, power output was significantly enhanced after CAFF+BJ and CAFF (3.0% and 3.9%, respectively, p supplementation when used alone (-0.4%, p = 0.6 compared with CONT) or when combined with caffeine (-0.9%, p = 0.4 compared with CAFF). We conclude that caffeine (3 mg·kg(-1) BM) administered in the form of a caffeinated gum increased cycling TT performance lasting ∼50-60 min by ∼3%-4% in both males and females. Beetroot juice supplementation was not ergogenic under the conditions of this study.

    Full Text Available This study was designed to determine the influence of 6 weeks’ MonaVie juice supplementation on body composition and hydration status in young elderly physically active women. Sixteen women, students of University of Third Age, were recruited for this study. All women were physically active (daily energy expenditure 1681.8 ± 297.6 kcal/d. Women were divided into 2 groups: 8 of them applied a supplement MonaVie juice (100 ml/d (S for 6 weeks, while the eight other women were allocated to the control group (C. There were measured: BW, Fat%, TBW, Hb, HCT and erythrocyte indices: RBC, mean corpuscular volume (MCV, mean corpuscular hemoglobin (MCH, mean corpuscular hemoglobin concentration (MCHC. Based on Hb and HCT were calculated changes: blood (del BV%, plasma (del PV% and cell (del CV% volumes in C and S group. Before experiment all body components and hematologic indices were similar in C and S group. After 6 weeks of MonaVie supplementation no significant changes in body composition but significant decrease: (MCH, (MCHC and an increase cell volume CV% + 2.89 ± 1.24% were found. In control group after 6 weeks period there were no significant changes in body components and hematological indices. These observations suggest that MonaVie supplementation does not induce significant changes in body composition and hydration status in young elderly women, however causes an increase of cells volume and a decrease of mean corpuscular hemoglobin concentration.

    This study tested the hypothesis that watermelon juice supplementation would improve nitric oxide bioavailability and exercise performance. Eight healthy recreationally-active adult males reported to the laboratory on two occasions for initial testing without dietary supplementation (control condition). Thereafter, participants were randomly assigned, in a cross-over experimental design, to receive 16 days of supplementation with 300 mL·day(-1) of a watermelon juice concentrate, which provided ∼3.4 g l-citrulline·day(-1) and an apple juice concentrate as a placebo. Participants reported to the laboratory on days 14 and 16 of supplementation to assess the effects of the interventions on blood pressure, plasma [l-citrulline], plasma [l-arginine], plasma [nitrite], muscle oxygenation and time-to-exhaustion during severe-intensity exercise. Compared to control and placebo, plasma [l-citrulline] (29 ± 4, 22 ± 6 and 101 ± 23 μM), [l-arginine] (74 ± 9, 67 ± 13 and 116 ± 9 μM) and [nitrite] (102 ± 29, 106 ± 21 and 201 ± 106 nM) were higher after watermelon juice supplementation (P juice (130 ± 11) and placebo (131 ± 9) conditions compared to the control condition (124 ± 8 mmHg; P juice condition than the placebo and control conditions (P juice: 550 ± 143 s) was not significantly different between conditions (P juice supplementation increased baseline plasma [nitrite] and improved muscle oxygenation during moderate-intensity exercise, it increased resting blood pressure and did not improve time-to-exhaustion during severe-intensity exercise. These findings do not support the use of watermelon juice supplementation as a nutritional intervention to lower blood pressure or improve endurance exercise performance in healthy adults.

    Healthcare professionals working in the community do not always prescribe oral nutritional supplements (ONS) according to best practice guidelines for the management of malnutrition. The present study aimed to determine the impact of a community dietetics intervention on ONS prescribing practices and expenditure 1 year later. The intervention involved general practitioners (GPs), practice nurses, nurses in local nursing homes and community nurses. It comprised an education programme together with the provision of a new community dietetics service. Changes in health care professionals' nutrition care practices were determined by examining community dietetics records. ONS prescribing volume and expenditure on ONS were assessed using data from the Primary Care Reimbursement Service of the Irish Health Service Executive. Seven out of 10 principal GPs participated in the nutrition education programme. One year later, screening for malnutrition risk was better, dietary advice was provided more often, referral to the community dietetics service improved and ONS were prescribed for a greater proportion of patients at 'high risk' of malnutrition than before (88% versus 37%; P dietetics intervention improved ONS prescribing practices by GPs and nurses, in accordance with best practice guidelines, without increasing expenditure on ONS during the year after intervention. © 2011 The Authors.

    Full Text Available Rearing Pelung chicken in Indonesia, in general, uses a ration with a high proportion of rice bran, even up to 60%. Considering the high contents of fiber, lignin, and phytic acid, feeding a high portion of rice bran will decrease nutrient digestibility. This study was aimed to evaluate the effect of lime juice supplementation of a rice bran-based ration on the utilization of nutrients in male Pelung chicken. Sixty four of 12 weeks old male Pelung chickens were used in the present experiment and assigned into a completely randomized block design. The treatments were supplementation of the ration with lime juice at the levels of 0, 1, 2, and 3 mL/100 g. Parameters measured were feed and nutrients consumption, protein, fat, and fiber digestibilities, apparent metabolizable energy (AME, rate of passage, feed conversion ratio (FCR, and daily body weight gain. The results showed that  the supplementation of lime juice in the ration did not affect feed and nutrient consumption, but significantly (P<0.05 increased the digestibilities of protein, fat and fiber, AME, rate of passage, FCR and daily body weight gain. However, supplementation  of 2 or 3 mL lime juice in the ration resulted in similar values of AME, and protein, fat and fiber digestibilities, and both levels of supplementation produced better protein and fat digestibilities, and AME when compared to the other treatments. It could be concluded that supplementation of 3 mL lime juice in the ration increased the digestion processes in the gastrointestinal and increased daily weight gain of male Pelung chicken.

    Ethanol production from sweet sorghum juice by Saccharomyces cerevisiae NP01 was investigated under very high gravity (VHG) fermentation and various carbon adjuncts and nitrogen sources. When sucrose was used as an adjunct, the sweet sorghum juice containing total sugar of 280 g l(-1), 3 g yeast extract l(-1) and 5 g peptone l(-1) gave the maximum ethanol production efficiency with concentration, productivity and yield of 120.68+/-0.54 g l(-1), 2.01+/-0.01 g l(-1) h(-1) and 0.51+/-0.00 g g(-1), respectively. When sugarcane molasses was used as an adjunct, the juice under the same conditions gave the maximum ethanol concentration, productivity and yield with the values of 109.34+/-0.78 g l(-1), 1.52+/-0.01 g l(-1) h(-1) and 0.45+/-0.01 g g(-1), respectively. In addition, ammonium sulphate was not suitable for use as a nitrogen supplement in the sweet sorghum juice for ethanol production since it caused the reduction in ethanol concentration and yield for approximately 14% when compared to those of the unsupplemented juices.

    NO3− supplementation via beetroot juice (BR) augments exercising skeletal muscle blood flow subsequent to its reduction to NO2− then NO. We tested the hypothesis that enhanced vascular control following BR would elevate the skeletal muscle O2 delivery/O2 utilization ratio (microvascular PO2, PmvO2) and raise the PmvO2 during the rest-contractions transition. Rats were administered BR (~0.8 mmol/kg/day, n=10) or water (control, n=10) for 5 days. PmvO2 was measured during 180 s of electrically-induced (1 Hz) twitch spinotrapezius muscle contractions. There were no changes in resting or contracting steady-state PmvO2. However, BR slowed the PmvO2 fall following contractions onset such that time to reach 63% of the initial PmvO2 fall increased (MRT1; control: 16.8±1.9, BR: 24.4±2.7 s, p<0.05) and there was a slower relative rate of PmvO2 fall (Δ1PmvO2/τ1; control: 1.9±0.3, BR: 1.2±0.2 mmHg/s, p<0.05). Despite no significant changes in contracting steady state PmvO2, BR supplementation elevated the O2 driving pressure during the crucial rest-contractions transients thereby providing a potential mechanism by which BR supplementation may improve metabolic control.

    Full Text Available Most of the components of poultry feed (80% of grains and meal that contains phytic acid which has anti-nutritional factor because it can bind minerals and reduce its availability. Phytic acid can be hydrolyzed by the enzyme phytase. Phytase enzyme naturally found in sugar cane juice, but its use as poultry feed supplements have not been done. The study was conducted using sugar cane juice PS 851 from Jatiroto PTPN XI, Lumajang, East Java in order to get the information potential of sugar cane juice as a liquid supplement and phytase enzyme carrier for poultry viewed from the aspect of nutrient content of sugarcane juice and phytase activity in the release rate of phosphorus. Research conducted at the Faculty of Animal IPB for 10 months. The rate of hydrolysis of phytase on P was tested using rice bran as a substrate. Sugar cane juice is added to the 2.5% level, using 4-level incubation (1, 2, 3 and 4 hours, each level consisting of 37°C and 42°C; pH 2; pH 4.5 and pH 5 with three replications. Study using a Two Factors Experiments in Completely Randomized Design and it was continued by DMRT test. P release rate was measured by spectrophotometry. The results showed that the sugar cane juice has a phytase activity of 0.0766 U / ml, brix level of 22.15%, containing water 73.03%, protein 0.47%, crude fiber 6.43%, minerals Ca 0.03%, P 0,02%, Co 0.14 mg / l, Fe 1.8 mg/l, Mn 1.55 mg/l, Zn 1.37 mg/ l, Cu 0.19 mg/ l, Se 12.63 mcg/100 g, vitamins B3 5.26 mg/100 g, C 0.72 mg/100 g, E 0.08 mg/100 g, sucrose 32.42%, fructose 2.41%, galactose 2% and glucose 1.58%. Supplementation of 2.5% sugar cane juice can increase the P release rate of 112-235% at optimum conditions of pH 5, at 37°C with a long incubation period of 1-4 hours.

    Sodium phosphate (SP) and beetroot juice (BJ) supplementation was assessed on repeated-sprint ability (RSA). Thirteen female team-sport participants completed four trials: (1) SP and BJ (SP + BJ), (2) SP and placebo (for BJ), (3) BJ and placebo (for SP) and (4) placebo (for SP + BJ), with ~21 days separating each trial. After each trial, participants performed a simulated team-game circuit (STGC) consisting of four 15 min quarters, with a 6 × 20-m repeated-sprint set performed at the start, half-time and end. Total sprint times were between 0.95-1.30 and 0.83-1.12 s faster for each RSA set and 3.25 and 3.12 s faster overall (~5% improvement) after SP compared with placebo and BJ, respectively (p = 0.02 for sets 1, 2 and overall; Cohen's effect size: d = -0.51 to -0.90 for all sets and overall). Additionally, total sprint times were 0.48 s faster after SP + BJ compared with placebo (set 2; p = 0.05, ~2% improvement). Furthermore, best sprints were 0.13-0.23 and 0.15-0.20 s faster (~6% improvement; p sprint times were faster after SP compared with placebo and BJ.

    It has been shown that nitrate supplementation can enhance endurance exercise performance. Recent work suggests that nitrate ingestion can also increase intermittent type exercise performance in recreational athletes. We hypothesized that six days of nitrate supplementation can improve high-intensity intermittent type exercise performance in trained soccer players. Thirty-two male soccer players (age: 23 ± 1 years, height: 181 ± 1 m, weight: 77 ± 1 kg, playing experience: 15.2 ± 0.5 years, playing in the first team of a 2nd or 3rd Dutch amateur league club) participated in this randomized, double-blind cross-over study. All subjects participated in two test days in which high-intensity intermittent running performance was assessed using the Yo-Yo IR1 test. Subjects ingested nitrate-rich (140 mL; ~800 mg nitrate/day; BR) or a nitrate-depleted beetroot juice (PLA) for six subsequent days, with at least eight days of wash-out between trials. The distance covered during the Yo-Yo IR1 was the primary outcome measure, while heart rate (HR) was measured continuously throughout the test, and a single blood and saliva sample were collected just prior to the test. Six days of BR ingestion increased plasma and salivary nitrate and nitrite concentrations in comparison to PLA (p < 0.001), and enhanced Yo-Yo IR1 test performance by 3.4 ± 1.3% (from 1574 ± 47 to 1623 ± 48 m; p = 0.027). Mean HR was lower in the BR (172 ± 2) vs. PLA trial (175 ± 2; p = 0.014). Six days of BR ingestion effectively improves high-intensity intermittent type exercise performance in trained soccer players. PMID:28327503

    Three types of Korean black raspberry wine were produced via alcoholic fermentation from juice, juice-pulp, and juice-pulp-seed, respectively. These wines were compared in terms of their anti-inflammatory activities and polyphenol contents. The total content of polyphenol compounds in wines was increased by 22.4% after supplementation with pulp and by 56.7% after supplementation with both pulp and seed. The reduction rate of NO evolution was highest in the order juice-pulp-seed wine, juice-pulp wine, and juice wine. Addition of the juice-pulp-seed wine at a level of 62.5-500 mg/L decreased the NO evolution rate by 40.5-94.2%. Eight fractions were obtained from juice-pulp-seed wine via ethyl acetate extraction and silica gel chromatography. Of these, the AF fraction, which exhibited the highest in vitro anti-inflammatory activity, exerted inhibitory effects on ear edema, writhing response, and vein membrane vascular permeability in mice. 3,4-Dihydroxybenzoic acid accounted for 37.6% of the total polyphenol content in the AF fraction.

    We evaluated the impact of a supplemental acerola juice (unripe, ripe, and industrial) and its main pharmaceutically active components on the concentrations of minerals in the liver and kidney of mice fed with cafeteria diet. Swiss male mice were fed with a cafeteria (CAF) diet for 13 weeks. The CAF consisted of a variety of supermarket products with high energy content. Subsequently, animals received one of the following food supplements for 1 month: water, unripe acerola juice, ripe acerola juice, industrial acerola juice, vitamin C, or rutin. Mineral concentrations of the tissues were determined by particle-induced X-ray emission (PIXE). Our study suggests that the simultaneous intake of acerola juices, vitamin C, or rutin in association with a hypercaloric and hyperlipidic diet provides change in the mineral composition of organisms in the conditions of this study, which plays an important role in the antioxidant defenses of the body. This may help to reduce the metabolism of the fat tissue or even to reduce the oxidative stress.

    The aim of our study was to investigate possible beneficial effects of organic chokeberry juice (OCJ) consumption in the treatment of cellulite. Twenty-nine women aged 25-48 with a cellulite grade 2 according to the Nurnberger-Muller scale were included. Anthropometric and biochemical parameters were measured. Skin structure was analyzed by ultrasonography. All subjects consumed 100 mL of OCJ per day, during 90 days. Measurements of investigated parameters were performed at 0, 45, and 90 days of the study. A marked reduction in the subcutaneous tissue thickness was observed in all subjects, with the average reduction of 1.9 mm. The length of subcutaneous tissue fascicles (ScTFL) was reduced in 97% (28 out of 29) of subjects, with the average value of 1.18 mm. After 45 days of chokeberry juice consumption, reduction of edema was observed in 55.2% of the subjects with edema at the baseline, while at the endpoint of the study, edemas were not observed in any of the subjects involved in the study. OCJ could have beneficial effects on the cellulite condition, including the length of ScTFL, subcutaneous tissue, and dermis thickness as well as on edema reduction.

  10. Should we prescribe calcium or vitamin D supplements to treat or prevent osteoporosis?

    Bolland, M J; Grey, A; Reid, I R

    2015-01-01

    Systematic reviews of randomized, controlled trials (RCTs) are considered the highest level of evidence to inform clinical practice. Meta-analyses of large RCTs of calcium and/or vitamin D supplements completed in the last 15 years provide strong evidence for clinical recommendations. These meta-analyses with data for > 50,000 older adults reported that calcium with or without vitamin D has only weak, inconsistent effects on fracture, and that vitamin D without calcium has no effect on fracture. Only one RCT of co-administered calcium and vitamin D in frail, institutionalized, elderly women with low dietary calcium intake and vitamin D levels showed significant reductions in fracture risk. These RCTs have also reported previously unrecognized adverse events of calcium supplements including kidney stones, myocardial infarction, hypercalcemia, and hospitalization with acute gastrointestinal symptoms. The small risk of these important adverse effects, together with the moderate risk of minor side-effects such as constipation, probably outweighs any benefits of calcium supplements on fracture. These data suggest the role for calcium and vitamin D supplements in osteoporosis management is very limited. Neither calcium nor vitamin D supplements should be recommended for fracture prevention in community-dwelling adults, although vitamin D should be considered for prevention of osteomalacia in at-risk individuals.

    Young coconut juice (Cocos nucifera Linn.) (YCJ) has traditionally been consumed to alleviate symptoms associated with menopause by women in Southeast Asia. The aim of the present study was to determine the effects of YCJ on bone metabolism in ovariectomized rats. Female 10-week-old Wistar rats were randomly assigned to the following 4 groups: Baseline, Sham, Ovx, and Ovx + YCJ (n = 10 rats per group). Rats in the Baseline group were sacrificed immediately, and those in the other groups were subjected to either sham operation (Sham) or bilateral ovariectomy (Ovx and Ovx + YCJ). The Ovx + YCJ rats were administered 5×-concentrated YCJ at a dose of 10 mL/kg body weight per day. Six weeks after surgery, the rats were sacrificed, and indices of bone mass and bone histomorphometry were measured. The bone mineral density of the left femur was significantly higher in the Ovx + YCJ group compared with the Ovx group. In addition, the Ovx + YCJ group showed significantly higher measurements for bone formation rate compared with the Ovx group. These findings suggest that YCJ supplementation has a positive effect on bone metabolism and thus represents a possible intervention to slow the bone loss observed following menopause.

    This study characterizes the antioxidant and antibacterial properties of a propolis-based dietary supplement (PDS) and investigates its incorporation into apple juice to decrease the intensity of the heat treatment required to inactivate 5 log10 cycles of Escherichia coli O157:H7. As the source of propolis, we used a PDS containing 0.2 mg/μL of propylene glycol-extracted propolis (propolis). The total phenolic content and antioxidant activity (IC50) of the PDS were 82.15±3.53 mg/g and 0.055±0.003 mg/mL, respectively. Regarding antimicrobial activity, propolis (0.2 mg/mL) was very effective under acidic pH against Listeria monocytogenes EGD-e, inactivating more than 5 log10 cell cycles in 1h, but hardly inactivated or sub-lethally injured E. coli O157:H7 Sakai. However, incorporating propolis (0.2 mg/mL) into acidic buffer decreased the time needed to inactivate 5 log10 cycles of E. coli O157:H7 Sakai at 51 °C by more than 40 times. Moreover, when combined with heat in apple juice, propolis (0.1mg/mL) reduced the thermal treatment time and temperature needed to inactivate 5 log10 cycles of E. coli by 75% and 3 °C, respectively. The corresponding PDS concentration did not decrease the organoleptic properties of the apple juice, which implies the possibility of obtaining a sensorially appealing, low-pasteurized apple juice with the functional properties provided by propolis.

    One of the most effective surgeries for sustainable weight loss in morbidly obese patients is laparoscopic sleeve gastrectomy (LSG). The present study aimed to assess the adherence of LSG patients with respect to following post-operative dietary requirements and micronutrient supplementation, as well as to investigate their perceived barriers in achieving optimal adherence. Retrospective data analysis was performed (3, 6, 9 and 12 months after LSG) using the medical records of 96 morbidly obese patients who had undergone LSG at our institution during 2011-2013. Data collected from patient records were: adherence to prescribed diet; adherence to prescribed consumption of fruit, vegetables, legumes and cereals; use of prescribed micronutrient supplements; and barriers to diet and micronutrient therapy adherence. Data were analysed using spss, version 14.0 (SPSS Inc., Chicago, IL, USA). At 3, 6, 9 and 12 months post-LSG, the rates of patient non-adherence to a prescribed diet were 39%, 45%, 51% and 74%, respectively. In particular, there was a low consumption of fruit, vegetables, legumes and cereals compared to the post-surgery prescription. In addition, the rates of patient non-adherence to prescribed micronutrient supplements at 3, 6, 9 and 12 months post-LSG were 43%, 51%, 59% and 67%, respectively. The main reasons for patient non-adherence to diet were poor self-discipline (72%) and poor family support (11%) whereas difficulty swallowing pills or capsules (61%) and cost (20%) were reported as the main barriers to post-LSG adherence. Morbidly obese patients who have undergone LSG do not follow exactly the post-operative dietary guidelines, including micronutrient therapy. © 2016 The British Dietetic Association Ltd.

    Agave (Agave tequilana Weber var. azul) fermentations are traditionally carried out employing batch systems in the process of tequila manufacturing; nevertheless, continuous cultures could be an attractive technological alternative to increase productivity and efficiency of sugar to ethanol conversion. However, agave juice (used as a culture medium) has nutritional deficiencies that limit the implementation of yeast continuous fermentations, resulting in high residual sugars and low fermentative rates. In this work, fermentations of agave juice using Saccharomyces cerevisiae were put into operation to prove the necessity of supplementing yeast extract, in order to alleviate nutritional deficiencies of agave juice. Furthermore, continuous fermentations were performed at two different aeration flow rates, and feeding sterilized and non-sterilized media. The obtained fermented musts were subsequently distilled to obtain tequila and the preference level was compared against two commercial tequilas, according to a sensorial analysis. The supplementation of agave juice with air and yeast extract augmented the fermentative capacity of S. cerevisiae S1 and the ethanol productivities, compared to those continuous fermentations non supplemented. In fact, aeration improved ethanol production from 37 to 40 g L(-1), reducing sugars consumption from 73 to 88 g L(-1) and ethanol productivity from 3.0 to 3.2 g (Lh)(-1), for non-aerated and aerated (at 0.02 vvm) cultures, respectively. Supplementation of yeast extract allowed an increase in specific growth rate and dilution rates (0.12 h(-1), compared to 0.08 h(-1) of non-supplemented cultures), ethanol production (47 g L(-1)), reducing sugars consumption (93 g L(-1)) and ethanol productivity [5.6 g (Lh)(-1)] were reached. Additionally, the effect of feeding sterilized or non-sterilized medium to the continuous cultures was compared, finding no significant differences between both types of cultures. The overall effect

    Red pitaya (Hylocereus polyrhizus) or known as buah naga merah in Malay belongs to the cactus family, Cactaceae. Red pitaya has been shown to give protection against liver damage and may reduce the stiffness of the heart. Besides, the beneficial effects of red pitaya against obesity have been reported; however, the mechanism of this protection is not clear. Therefore, in the present study, we have investigated the red pitaya-targeted genes in obesity using high-carbohydrate, high-fat diet-induced metabolic syndrome rat model. A total of four groups were tested: corn-starch (CS), corn-starch + red pitaya juice (CRP), high-carbohydrate, high-fat (HCHF) and high-carbohydrate, high-fat + red pitaya juice (HRP). The intervention with 5 % red pitaya juice was continued for 8 weeks after 8 weeks initiation of the diet. Retroperitoneal, epididymal and omental fat pads were collected and weighed. Plasma concentration of IL-6 and TNF-α were measured using commercial kits. Gene expression analysis was conducted using RNA extracted from liver samples. A total of eighty-four genes related to obesity were analyzed using PCR array. The rats fed HCHF-diet for 16 weeks increased body weight, developed excess abdominal fat deposition and down-regulated the expression level of IL-1α, IL-1r1, and Cntfr as compared to the control group. Supplementation of red pitaya juice for 8 weeks increased omental and epididymal fat but no change in retroperitoneal fat was observed. Red pitaya juice reversed the changes in energy balance homeostasis in liver tissues by regulation of the expression levels of Pomc and Insr. The increased protein expression levels of IL-6 and TNF-α in HCHF group and red pitaya treated rats confirmed the results of gene expression. Collectively, this study revealed the usefulness of this diet-induced rat model and the beneficial effects of red pitaya on energy balance homeostasis by modulating the anorectic, orexigenic and energy expenditure related

    Acute dietary nitrate ([Formula: see text]) supplementation reduces resting blood pressure in healthy normotensives. This response has been attributed to increased nitric oxide bioavailability and peripheral vasodilation, although nitric oxide also tonically inhibits central sympathetic outflow. We hypothesized that acute dietary [Formula: see text] supplementation using beetroot (BR) juice would reduce blood pressure and muscle sympathetic nerve activity (MSNA) at rest and during exercise. Fourteen participants (7 men and 7 women, age: 25 ± 10 yr) underwent blood pressure and MSNA measurements before and after (165-180 min) ingestion of 70ml high-[Formula: see text] (~6.4 mmol [Formula: see text]) BR or [Formula: see text]-depleted BR placebo (PL; ~0.0055 mmol [Formula: see text]) in a double-blind, randomized, crossover design. Blood pressure and MSNA were also collected during 2 min of static handgrip (30% maximal voluntary contraction). The changes in resting MSNA burst frequency (-3 ± 5 vs. 3 ± 4 bursts/min, P = 0.001) and burst incidence (-4 ± 7 vs. 4 ± 5 bursts/100 heart beats, P = 0.002) were lower after BR versus PL, whereas systolic blood pressure (-1 ± 5 vs. 2 ± 5 mmHg, P = 0.30) and diastolic blood pressure (4 ± 5 vs. 5 ± 7 mmHg, P = 0.68) as well as spontaneous arterial sympathetic baroreflex sensitivity (P = 0.95) were not different. During static handgrip, the change in MSNA burst incidence (1 ± 8 vs. 8 ± 9 bursts/100 heart beats, P = 0.04) was lower after BR versus PL, whereas MSNA burst frequency (6 ± 6 vs. 11 ± 10 bursts/min, P = 0.11) as well as systolic blood pressure (11 ± 7 vs. 12 ± 8 mmHg, P = 0.94) and diastolic blood pressure (11 ± 4 vs. 11 ± 4 mmHg, P = 0.60) were not different. Collectively, these data provide proof of principle that acute BR supplementation can decrease central sympathetic outflow at rest and during exercise. Dietary [Formula: see text] supplementation may represent a novel intervention to target

    Background Recent studies have demonstrated a correlation between perceived stress and oxidative stress. As SOD is the main enzyme of the enzymatic antioxidant defence system of the body, we evaluated the effect of an oral daily intake of a proprietary melon juice concentrate rich in SOD (EXTRAMEL®) on the signs and symptoms of stress and fatigue in healthy volunteers. Methods This randomized, double blind, placebo controlled clinical study was conducted with seventy healthy volunteers aged between 30 and 55 years, who feel daily stress and fatigue. They took the dietary supplement based on the melon juice concentrate (10 mg Extramel® corresponding to 140 IU SOD per capsule) or a placebo one time daily during 4 weeks. Stress and fatigue were measured using four observational psychometric scales: FARD, PSS-14, SF-12 and Epworth scale. The study was conducted by Isoclin, a clinical research organization, located in Poitiers, France. Results No adverse effect was noted. The supplementation with the proprietary melon juice concentrate bringing 140 IU SOD/day significantly improved signs and symptoms of stress and fatigue linked to performance, physical (pain, sleep troubles), cognitive (concentration, weariness, sleep troubles) or behavioural (attitude, irritability, difficulty of contact) compared to the placebo. In the same way, quality of life and perceived stress were significantly improved with SOD supplementation. Conclusion This pilot study showed that an oral supplementation with a proprietary melon juice concentrate rich in SOD may have a positive effect on several signs and symptoms of perceived stress and fatigue.

    Full Text Available Children with autism spectrum disorders (ASD have several risk factors for low bone mineral density. The gluten-free, casein-free (GFCF diet is a complementary therapy sometimes used in ASD that raises concerns for the adequacy of calcium and vitamin D intake. This study evaluated the prescribing practices of calcium and vitamin D supplements and the practice of checking 25-hydroxy vitamin D (25(OHD levels by providers in 100 children with ASD, 50 of whom were on the GFCF diet. Fifty-two percent and 46% of children on the GFCF diet were on some form of vitamin D and calcium supplements, respectively, compared to 18% and 14% of those not on this diet. Twenty-four percent of children in the GFCF group had a documented 25(OHD level compared to none in the non-GFCF group. The data highlight a gap in calcium and vitamin D supplement prescribing practices among providers caring for children with ASD as well as a gap in the practice of checking 25(OHD levels.

    Tart cherries are a particularly rich source of anthocyanins. Evidence indicates that dietary intake of anthocyanins is inversely associated with arterial stiffness. We conducted an open-label randomised placebo controlled study to determine whether a tart cherry juice concentrate (Cherry Active) reduced arterial stiffness, inflammation and risk markers for cardiovascular disease in 47 healthy adults (30-50 years). Participants consumed 30 ml of cherry concentrate diluted to a volume of 250 ml with water or the same volume of an energy matched control drink daily for six weeks. Measurements were taken at baseline and at the end of the intervention. There was no effect of the intervention on arterial stiffness (P = 0.218), c-reactive protein (P = 0.220), systolic blood pressure (P = 0.163), diastolic blood pressure (P = 0.121), total cholesterol (P = 0.342) and high density lipoprotein cholesterol (P = 0.127). At the end of the intervention, plasma antioxidant capacity (measured as the ferric reducing ability of plasma (FRAP)) was significantly higher in the intervention group than the control group (P = 0.012). We conclude that a tart cherry juice concentrate rich in anthocyanins has no effect on arterial stiffness, c-reactive protein and risk markers for cardiovascular disease, but evokes a minor increase in antioxidant status in healthy adults.

    Hypertension is a major risk factor for cardiovascular disease and has a prevalence of about one billion people worldwide. It has been shown that adherence to a diet rich in fruits and vegetables helps in decreasing blood pressure (BP). This study aimed to investigate the effect of raw beet juice (RBJ) and cooked beet (CB) on BP of hypertensive subjects. In this randomized crossover study, 24 hypertensive subjects aged 25-68 years old were divided into two groups. One group took RBJ for 2 weeks and the other group took CB. After 2 weeks of treatment, both groups had a washout for 2 weeks then switched to the alternate treatment. Each participant consumed 250 ml day(-1) of RBJ or 250 g day(-1) of CB each for a period of 2 weeks. Body weight, BP, flow-mediated dilation (FMD), lipid profile and inflammatory parameters were measured at baseline and after each period. According to the results, high-sensitivity C-reactive protein (hs-CRP) and tumour necrosis factor alpha (TNF-α) were significantly lower and FMD was significantly higher after treatment with RBJ compared with CB (P<0.05). FMD was significantly (P<0.05) increased, but systolic and diastolic BP, intracellular adhesion molecule-1 (ICAM-1), vascular endothelial adhesion molecule-1 (VCAM-1), hs-CRP, interleukin-6, E-selectin and TNF-α were significantly (P<0.05) decreased with RBJ or CB. Total antioxidant capacity was increased and non-high-density lipoprotein (HDL), low-density lipoprotein (LDL) and total cholesterol (TC) were decreased with RBJ but not with CB. Although both forms of beetroot were effective in improving BP, endothelial function and systemic inflammation, the raw beetroot juice had greater antihypertensive effects. Also more improvement was observed in endothelial function and systemic inflammation with RBJ compared with CB.

    Pomegranates have health-promoting benefits because of their polyphenol constituents. Previous studies have demonstrated the antimicrobial activity of aqueous and organic extracts of pomegranate components and by-products. We sought to determine the antimicrobial activity against 40 foodborne pathogens representing eight bacterial species using juice itself. In addition, we sought to determine the synergistic antimicrobial activity between pomegranate juice and other plant products displaying antimicrobial activity. The antimicrobial activity of pomegranate juice was dependent on the test organism, which varied to highly susceptible (four Gram-positive species) to unaffected (Salmonella and Escherichia coli O157:H7). Two Gram-negative species, which were inhibited were Helicobacter pylori and Vibrio parahemolyticus. No synergistic antimicrobial activity was seen between pomegranate and either barberry, oregano, or cranberry. The antimicrobial activity of pomegranate juice is dependent on the test organism and extraction method. The sensitivity of H. pylori suggests that pomegranate juice may be an alternative or supplemental treatment for gastric ulcers caused by this organism.

    Sour cherry juice (Prunus cerasus) is consumed as a nutritional supplement claiming health effects. The aim of the study was to evaluate the different properties of sour cherry juice in terms of antioxidant activity and inhibition of target enzymes in the central nervous system and diabetes. The content of polyphenols and anthocyanins was quantified. Different experiments were carried out to determine the radical scavenging properties of the juice. The activity of sour cherry juice was also tested in physiological relevant enzymes of the central nervous system (acetylcholinesterase, monoamine oxidase A, tyrosinase) and others involved in type 2 diabetes (α-glucosidase, dipeptidyl peptidase-4). Sour cherry juice showed significant antioxidant effects but the activity of the lyophilized juice was not superior to compounds such as ascorbic, gallic or chlorogenic acid. Furthermore, sour cherry juice and one of its main polyphenols known as chlorogenic acid were also able to inhibit monoamine oxidase A and tyrosinase as well as enzymes involved in diabetes. This is the first time that sour cherry juice is reported to inhibit monoamine oxidase A, α-glucosidase and dipeptidyl peptidase-4 in a dose dependent manner, which may be of interest for human health and the prevention of certain diseases.

    Nurse prescribing has been established in the UK since 1994, however, limited focus has been placed on the experiences of district nurses adopting this additional role. This phenomenological study explores the experiences of district nurses prescribing as nurse independent prescribers across the West of Scotland. A qualitative Heideggarian approach examined the every-day experiences of independent prescribing among district nurses. A purposive sample was used and data collected using audio taped one-to-one informal interviews. The data was analysed thematically using Colaizzi's seven procedural steps. Overall these nurses reported that nurse prescribing was a predominantly positive experience. Participants identified improvements in patient care, job satisfaction, level of autonomy and role development. However, some of the participants indicated that issues such as support, record keeping, confidence and ongoing education are all major influences on prescribing practices.

    2016-01-01

    We determined the validity of current medical advice to avoid grapefruit juice consumption while taking 3 widely used statins. A daily glass of grapefruit juice increases blood levels of simvastatin and lovastatin by about 260% if taken at the same time (about 90% if taken 12 hours apart), and atorvastatin by about 80% (whenever taken). Simvastatin 40 mg, lovastatin 40 mg, and atorvastatin 10 mg daily reduce low-density lipoprotein (LDL) cholesterol levels in a 60-year-old man with an LDL cholesterol of 4.8 mmol/L by 37%, reducing ischemic heart disease risk by 61%. When simvastatin or lovastatin are taken at the same time as grapefruit juice, the estimated reduction in LDL cholesterol is 48%, and in heart disease is 70%. If the juice is taken 12 hours before these statins, the reductions are, respectively, 43% and 66%, and for atorvastatin, 42% and 66%. The increased rhabdomyolysis risk from grapefruit juice consumption due to the increased effective statin dose is minimal compared with the greater effect in preventing heart disease. Grapefruit juice should not be contraindicated in people taking statins.

    A three-stage continuous fermentative colonic model system was used to monitor in vitro the effect of different orange juice formulations on prebiotic activity. Three different juices with and without Bimuno, a GOS mixture containing galactooligosaccharides (B-GOS) were assessed in terms of their ability to induce a bifidogenic microbiota. The recipe development was based on incorporating 2.75g B-GOS into a 250 ml serving of juice (65°Brix of concentrate juice). Alongside the production of B-GOS juice, a control juice--orange juice without any additional Bimuno and a positive control juice, containing all the components of Bimuno (glucose, galactose and lactose) in the same relative proportions with the exception of B-GOS were developed. Ion Exchange Chromotography analysis was used to test the maintenance of bimuno components after the production process. Data showed that sterilisation had no significant effect on concentration of B-GOS and simple sugars. The three juice formulations were digested under conditions resembling the gastric and small intestinal environments. Main bacterial groups of the faecal microbiota were evaluated throughout the colonic model study using 16S rRNA-based fluorescence in situ hybridization (FISH). Potential effects of supplementation of the juices on microbial metabolism were studied measuring short chain fatty acids (SCFAs) using gas chromatography. Furthermore, B-GOS juices showed positive modulations of the microbiota composition and metabolic activity. In particular, numbers of faecal bifidobacteria and lactobacilli were significantly higher when B-GOS juice was fermented compared to controls. Furthermore, fermentation of B-GOS juice resulted in an increase in Roseburia subcluster and concomitantly increased butyrate production, which is of potential benefit to the host. In conclusion, this study has shown B-GOS within orange juice can have a beneficial effect on the fecal microbiota.

  14. Educating nonmedical prescribers.

    Stewart, Derek; MacLure, Katie; George, Johnson

    2012-10-01

    The last decade has seen developments in nonmedical prescribing, with the introduction of prescribing rights for healthcare professionals. In this article, we focus on the education, training and practice of nonmedical prescribers in the UK. There are around 20,000 nurse independent prescribers, 2400 pharmacist supplementary/independent prescribers, several hundred allied health professional supplementary prescribers and almost 100 optometrist supplementary/independent prescribers. Many are active prescribers, managing chronic conditions or acute episodes of infections and minor ailments. Key aims of nonmedical prescribing are as follows: to improve patient care; to increase patient choice in accessing medicines; and to make better use of the skills of health professionals. Education and training are provided by higher education institutions accredited by UK professional bodies/regulators,namely, the Nursing and Midwifery Council, General Pharmaceutical Council, Health Professions Council and General Optical Council. The programme comprises two main components: a university component equivalent to 26 days full-time education and a period of learning in practice of 12 days minimum under the supervision of a designated medical practitioner. Course content focuses on the following factors: consultation, decision making, assessment and review; psychology of prescribing; prescribing in team context; applied therapeutics; evidence-based practice and clinical governance; legal, policy, professional and ethical aspects; and prescribing in the public health context. Nonmedical prescribers must practise within their competence, demonstrating continuing professional development to maintain the quality engendered during training. Despite the substantial progress, there are several issues of strategy, capacity, sustainability and a research evidence base which require attention to fully integrate nonmedical prescribing within healthcare. © 2012 The Authors.

  16. Cyclosporine and Herbal Supplement Interactions

    Directory of Open Access Journals (Sweden)

    D. Colombo

    2014-01-01

    Full Text Available Cyclosporine (CyA is a well-known immunosuppressant with a narrow therapeutic window. Its bioavailability is affected by many other traditional drugs and herbal extracts. Cytochrome P-450 isoenzymes CYP3A4 and CYP3A5 and protein P-glycoprotein (P-gp are involved in CyA bioavailability. Interactions of CyA with herbal extracts are not well known, but, given their increased concomitant use, it is important to know which extracts, many of which are commonly self-prescribed, can affect CyA blood concentrations. Decreased CyA blood concentration has been shown with St John’s wort in case reports and, in vivo animal studies, with ginger, liquorice, scutellariae radix, and quercetin. Increased CyA concentration has been reported in patients with grapefruit juice, chamomile, or berberine, and with cannabidiol or resveratrol in animal studies. Effects of Echinacea and Serenoa repens on CyA levels have not been shown consistently, but concomitant use should be avoided. Although findings from animal studies cannot be directly translated into humans, avoiding concomitant use of herbal extracts is prudent until human clinical studies have ruled out any possible interaction. Clinicians should interview their patients carefully about their use of herbal supplements before CyA administration, and those receiving CyA should be warned about possible interactions between herbal preparations and CyA.

    Since an oral regimen of levodopa has been instituted for treatment of Parkinson's disease, its absorption and metabolism has been well demonstrated. However, its chemical characteristics of high solubility in acid solution and low solubility in water have not been well known. We paid attention to this characteristic and studied the relationship between its absorption and gastric acid secretion in 38 patients with Parkinson's disease who became refractory to therapy of levodopa. We measured the pH and amount of collected fasting gastric juice. Gastric acid secretion was decreased in 22 patients (58%). In ten of these 22 patients, 30 ml of lemon juice was prescribed in every administration of levodopa as a supplement to gastric acid for two weeks. Increases of L-dopa concentration after 60 min. and 180 min. were observed after lemon juice supplement therapy. Among the Parkinson symptoms, rigidity, akinesia, and small step gait were improved in every case except one patient who showed decrease of L-dopa concentration at 180 minutes. However, improvement of tremor was less remarkable. We consider this supplement therapy to gastric acid is one of the effective and useful methods in the management of Parkinson's disease.

    Juice was extracted from jicama (Pachyrrizus erosus Urban) and clarified using a 10,000 daltons molecular weight cut-off membrane to improve its stability. Ultrafiltered juice was tested for general composition and Hunter color. Ultrafiltration (UF) retentate and UF permeate showed some changes, compared to fresh juice, in total and soluble solids, total sugars, and nitrogen, whereas ash and pH remained constant. Hunter color of juice samples exhibited some variation by UF. Results suggest that UF has potential to produce jicama juice with desirable and stable aroma and flavor.

  20. Changing physician prescribing behaviour.

    Science.gov (United States)

    Gray, J

    2006-01-01

    Didactic approaches to educating physicians and/or other health professionals do not produce changes in learner behaviour. Similarly, printed materials and practice guidelines have not been shown to change prescribing behaviour. Evidence-based educational approaches that do have an impact on provider behaviour include: teaching aimed at identified learning needs; interactive educational activities; sequenced and multifaceted interventions; enabling tools such as patient education programs, flow charts, and reminders; educational outreach or academic detailing; and audit and feedback to prescribers. Dr. Jean Gray reflects over the past 25 years on how there has been a transformation in the types of activities employed to improve prescribing practices in Nova Scotia. The evolution of Continuing Medical Education (CME) has resulted in the creation of the Drug Evaluation Alliance of Nova Scotia (DEANS) program, which is one exemplar of an evidence-based educational approach to improving physician prescribing in that province. Key words: Evidence-based, education, prescribing.

  1. Effect of storage in juice with or without pulp and/or calcium lactate on the subsequent survival of Escherichia coli O157:H7 in simulated gastric fluid.

    2008-04-30

    A study was conducted to evaluate the effect of storing Escherichia coli O157:H7 in fruit or vegetable juices with or without pulp and/or calcium lactate, on the bacterial resistance to a simulated gastric fluid (SGF, pH 1.5). Apple, carrot, orange, and tomato juices containing pulp or freed from pulp by filtration were used in this study. Calcium lactate at about 1.4 g/l was added to juices to obtain calcium supplemented juices. Juices with or without pulp and/or calcium lactate were inoculated with E. coli O157:H7 and then were stored at 7 degrees C for 0, 1, 2, or 4 days. The acid resistance of cells stored in juices with or without pulp and/or calcium lactate was determined by incubating in SGF for 90 or 240 min at 37 degrees C. Cells stored in apple juice for 4 days, carrot juice for 2 days, and orange juice for 4 days with pulp only had greater acid resistance, while all cells stored in tomato juice with pulp had greater acid resistance than cells stored in juice without pulp. The D-values of cells stored in supplemented apple and orange juices with calcium lactate declined 1.7-3.5 fold, whereas D-values of cells stored in supplemented tomato juice decreased by about 1.4-fold when compared to cells stored in juice without calcium lactate after exposure in SGF. These results indicate that storing E. coli O157:H7 in juices with pulp had little or no effect on the acid resistance of cells during subsequent exposure in SGF. Calcium lactate supplemented into juices could dramatically decrease the ability of E. coli O157:H7 to survive in SGF, possibly reducing the risk of foodborne illness by juice products.

    2013-10-01

    The purpose of this review was to examine the effect of nitrate supplementation on exercise performance by systematic review and meta-analysis of controlled human studies. A search of four electronic databases and cross-referencing found 17 studies investigating the effect of inorganic nitrate supplementation on exercise performance that met the inclusion criteria. Beetroot juice and sodium nitrate were the most common supplements, with doses ranging from 300 to 600 mg nitrate and prescribed in a manner ranging from a single bolus to 15 days of regular ingestion. Pooled analysis showed a significant moderate benefit (ES = 0.79, 95% CI: 0.23-1.35) of nitrate supplementation on performance for time to exhaustion tests (p = .006). There was a small but insignificant beneficial effect on performance for time trials (ES = 0.11, 95% CI: -0.16-0.37) and graded exercise tests (ES = 0.26, 95% CI: -0.10-0.62). Qualitative analysis suggested that performance benefits are more often observed in inactive to recreationally active individuals and when a chronic loading of nitrate over several days is undertaken. Overall, these results suggest that nitrate supplementation is associated with a moderate improvement in constant load time to exhaustion tasks. Despite not reaching statistical significance, the small positive effect on time trial or graded exercise performance may be meaningful in an elite sport context. More data are required to clarify the effect of nitrate supplementation on exercise performance and to elucidate the optimal way to implement supplementation.

    Vinegar is widely used as a food additive, in food preparation and as a food supplement. This study compared the phenolic acid profiles and in vivo toxicities, and antioxidant and immunomodulatory effects of coconut, nipah and pineapple juice vinegars, which were respectively prepared via a two-step fermentation using Saccharomyces cerevisiae 7013 INRA and Acetobacter aceti vat Europeans. Pineapple juice vinegar, which had the highest total phenolic acid content, also exhibited the greatest in vitro antioxidant capacity compared to coconut juice and nipah juice vinegars. Following acute and sub-chronic in vivo toxicity evaluation, no toxicity and mortality were evident and there were no significant differences in the serum biochemical profiles between mice administered the vinegars versus the control group. In the sub-chronic toxicity evaluation, the highest liver antioxidant levels were found in mice fed with pineapple juice vinegar, followed by coconut juice and nipah juice vinegars. However, compared to the pineapple juice and nipah juice vinegars, the mice fed with coconut juice vinegar, exhibited a higher population of CD4(+) and CD8(+) T-lymphocytes in the spleen, which was associated with greater levels of serum interleukin-2 and interferon-γ cytokines. Overall, the data suggested that not all vinegar samples cause acute and sub-chronic toxicity in vivo. Moreover, the in vivo immunity and organ antioxidant levels were enhanced, to varying extents, by the phenolic acids present in the vinegars. The results obtained in this study provide appropriate guidelines for further in vivo bioactivity studies and pre-clinical assessments of vinegar consumption. © 2017 Society of Chemical Industry. © 2017 Society of Chemical Industry.

The database consisted of data from a mix of authentic and adulterated samples. Statistical tools were used to reduce the database to a stable sample set of 477 presumably authentic samples. The profile obtained (mean, SD at 16 Brix) are as follows: fructose (g/100 g) 6.83, 0.50; glucose (g/100 g) 6.66, 0.44; sucrose (g/100 g) 0.00, 0.00; sorbitol (g/100 g) 0.00, 0.01; acidity (g/100 g as citric acid) 1.25, 0.32; citric acid (g/100 g) 1.19, 0.30; malic acid (g/100 g) 0.065, 0.034; tartaric acid (g/100 g) 0.00, 0.00; isocitric acid (mg/kg) 63, 21; potassium (mg/kg) 2320, 400; proline (mg/kg) 7, 5; formol value [milliequivalents/100 g] 1.00, 0.24; 13C/12C ratio [o/oo Pee Dee belemnite]-26.4, 0.8. The profile samples had a consistent anthocyanin pattern consisting of four major peaks corresponding to delphinidin-3,5-diglucoside, delphinidin-3-glucoside, cyanidin-3,5-diglucoside, and cyanidin-3-glucoside. Minor peaks corresponding to pelargonidin-3,5-diglucoside and pelargonidin-3-glucoside were also generally present. No maltose, D-malic acid, or tartaric acid were detected in any of the samples. The profile obtained corresponds closely with previously published data.

    Recent studies have indicated that certain food products have ergogenic potential similar to that of sports supplements. The present study aimed to investigate the potential ergogenic effect of integral purple grape juice on the performance of recreational runners. Twenty-eight volunteers of both sexes (age, 39.8 ± 8.5 years; peak oxygen consumption, 43.2 ± 8.5 mL/(kg·min)) were randomized into either a group that received grape juice (grape juice group (GJG), n = 15; 10 mL/(kg·min) for 28 days) or a group that received an isocaloric, isoglycemic, and isovolumetric control beverage (control group (CG), n = 13). A time-to-exhaustion exercise test, anaerobic threshold test, and aerobic capacity test were performed, together with assessments of markers of oxidative stress, inflammation, immune response, and muscle injury, performed at baseline and 48 h after the supplementation protocol. The GJG showed a significant increase (15.3%) in running time-to-exhaustion (p = 0.002) without significant improvements in either anaerobic threshold (3.6%; p = 0.511) or aerobic capacity (2.2%; p = 0.605). In addition, GJG exhibited significant increases in total antioxidant capacity (38.7%; p = 0.009), vitamin A (11.8%; p = 0.016), and uric acid (28.2%; p = 0.005), whereas α-1-acid glycoprotein significantly decreased (20.2%; p = 0.006) and high-sensitivity C-reactive protein levels remained unchanged. In contrast, no significant changes occurred in any of these variables in the CG. In conclusion, supplementation with purple grape juice shows an ergogenic effect in recreational runners by promoting increased time-to-exhaustion, accompanied by increased antioxidant activity and a possible reduction in inflammatory markers.

    The bacterial pathogen Campylobacter jejuni is primarily transmitted via the consumption of contaminated foodstuffs, especially poultry meat. In food processing environments, C. jejuni is required to survive a multitude of stresses and requires the use of specific survival mechanisms, such as biofilms. An initial step in biofilm formation is bacterial attachment to a surface. Here, we investigated the effects of a chicken meat exudate (chicken juice) on C. jejuni surface attachment and biofilm formation. Supplementation of brucella broth with ≥5% chicken juice resulted in increased biofilm formation on glass, polystyrene, and stainless steel surfaces with four C. jejuni isolates and one C. coli isolate in both microaerobic and aerobic conditions. When incubated with chicken juice, C. jejuni was both able to grow and form biofilms in static cultures in aerobic conditions. Electron microscopy showed that C. jejuni cells were associated with chicken juice particulates attached to the abiotic surface rather than the surface itself. This suggests that chicken juice contributes to C. jejuni biofilm formation by covering and conditioning the abiotic surface and is a source of nutrients. Chicken juice was able to complement the reduction in biofilm formation of an aflagellated mutant of C. jejuni, indicating that chicken juice may support food chain transmission of isolates with lowered motility. We provide here a useful model for studying the interaction of C. jejuni biofilms in food chain-relevant conditions and also show a possible mechanism for C. jejuni cell attachment and biofilm initiation on abiotic surfaces within the food chain.

    This investigation determined the efficacy of a tart cherry juice in aiding recovery and reducing muscle damage, inflammation and oxidative stress. Twenty recreational Marathon runners assigned to either consumed cherry juice or placebo for 5 days before, the day of and for 48 h following a Marathon run. Markers of muscle damage (creatine kinase, lactate dehydrogenase, muscle soreness and isometric strength), inflammation [interleukin-6 (IL-6), C-reactive protein (CRP) and uric acid], total antioxidant status (TAS) and oxidative stress [thiobarbituric acid reactive species (TBARS) and protein carbonyls] were examined before and following the race. Isometric strength recovered significantly faster (P=0.024) in the cherry juice group. No other damage indices were significantly different. Inflammation was reduced in the cherry juice group (IL-6, Pcherry juice than the placebo group for all post-supplementation measures (Pcherry juice than the placebo at 48 h (Pcherry juice appears to provide a viable means to aid recovery following strenuous exercise by increasing total antioxidative capacity, reducing inflammation, lipid peroxidation and so aiding in the recovery of muscle function.

    Grape contains flavonoids with antioxidant properties which are believed to be protective against various types of cancer. This antioxidative protection is possibly provided by the effective scavenging of reactive oxygen species (ROS), thus defending cellular DNA from oxidative damage and potential mutations. This study of healthy adults tested whether a daily regimen of grape juice supplementation could reduce cellular DNA damage in peripheral lymphocytes and reduce the amount of free radicals released. Sixty-seven healthy volunteers (16 women and 51 men) aged 19-57 years were given 480 ml of grape juice daily for 8 weeks in addition to their normal diet, and blood samples were drawn before and after the intervention. The DNA damage was determined by using the single cell gel (comet) assay with alkaline electrophoresis and was quantified by measuring tail length (TL). Levels of free radicals were determined by reading the lucigenin-perborate ROS generating source, using the Ultra-Weak Chemiluminescence Analyzer System. Grape juice consumption resulted in a significant decrease in lymphocyte DNA damage expressed by TL (before supplementation: 88.75{+-}1.55 {mu}m versus after supplementation: 70.25{+-}1.31 {mu}m; P=0.000 by paired t-test). Additionally, grape juice consumption for 8 weeks reduced the ROS/photon count by 15%, compared to the beginning of the study. The preventive effect of grape juice against DNA damage was simultaneously shown in both sexes. These results indicate that the consumption of grape juice may increase plasma antioxidant capacity, resulting in reduced DNA damage in peripheral lymphocytes achieved at least partially by a reduced release of ROS. Our findings support the hypothesis that polyphenolic compounds contained in grape juice exert cancer-protective effects on lymphocytes, limiting oxidative DNA damage possibly via a decrease in free radical levels.

    The 2015 to 2020 Dietary Guidelines for Americans (DGAs) recognize the role of 100% fruit juice in health and in helping people meet daily fruit recommendations and state that 100% fruit juice is a nutrient-dense beverage that should be a primary choice, along with water and low-fat/fat-free milk. The DGAs note that children are consuming 100% fruit juice within recommendations (that is, 120 to 180 mL/d for children aged 1 to 6 y and 236 to 355 mL/d for children aged 7 to 18 y). Evidence shows that compared to nonconsumers, those who consume 100% fruit juice come closer to meeting daily fruit needs and have better diet quality. In children, 100% fruit juice is associated with increased intakes of nutrients such as vitamin C, folate, and potassium. When consumed within the DGA recommendations, 100% fruit juice is not associated with overweight/obesity or childhood dental caries and does not compromise fiber intake. Preliminary data suggest that polyphenols in some 100% fruit juices may inhibit absorption of naturally occurring sugars. Given its role in promoting health and in helping people meet fruit needs, experts participating in a roundtable discussion agreed that there is no science-based reason to restrict access to 100% fruit juice in public health nutrition policy and programs such as the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC). Reducing or eliminating 100% fruit juice could lead to unintended consequences such as reduced daily fruit intake and increased consumption of less nutritious beverages (for example, sugar-sweetened beverages). © 2017 Institute of Food Technologists®.

    Campylobacter and Salmonella are leading causes of foodborne illnesses worldwide, vastly harboured by raw meat as their common food reservoir. Both microbes are prevalent in meat processing environments in the form of biofilms that contribute to cross-contamination and foodborne infection. This study applied raw meat juice (chicken juice and pork juice) as a minimally processed food model to study its effects on bacterial biofilm formation. Meat juice was collected during the freeze-thaw process of raw meat and sterilized by filtration. In 96-well polystyrene plates and glass chambers, supplementation of over 25% meat juice (v/v) in laboratory media led to an increase in biofilm formation of Campylobacter and Salmonella. During the initial attachment stage of biofilm development, more bacterial cells were present on surfaces treated with meat juice residues compared to control surfaces. Meat juice particulates on abiotic surfaces facilitated biofilm formation of Campylobacter and Salmonella under both static and flow conditions, with the latter being assessed using a microfluidic platform. Further, the deficiency in biofilm formation of selected Campylobacter and Salmonella mutant strains was restored in the presence of meat juice particulates. These results suggested that meat juice residues on the abiotic surfaces might act as a surface conditioner to support initial attachment and biofilm formation of Campylobacter and Salmonella. This study sheds light on a possible survival mechanism of Campylobacter and Salmonella in meat processing environments, and indicates that thorough cleaning of meat residues during meat production and handling is critical to reduce the bacterial load of Campylobacter and Salmonella.

    Noni juice (Morinda citrifolia) has been approved for use as a safe food within the European Union, following a review of safety. Since approval, three cases of acute hepatitis in Austrian noni juice consumers have been published, where a causal link is suggested between the liver dysfunction and ingestion of anthraquinones from the plant. Measurements of liver function in a human clinical safety study of TAHITIAN NONI(R) Juice,as well as subacute and subchronic animal toxicity tests revealed no evidence of adverse liver effects at doses many times higher than those reported in the case studies. Additionally, M. Citrifolia anthraquinones occur in the fruit in quantities too small to be of any toxicological significance. Further, these do not have chemical structures capable of being reduced to reactive anthrone radicals, which were implicated in previous cases of herbal hepototoxicity. The available data reveals no evidence of liver toxicity.

    Full Text Available The main objective of this research was to study the effects of processing conditions, i.e. cooling medium temperature (-6, -12 and -18C and scraper blade rotational speed (50, 100 and 150 rpm on the freeze concentration of lime juice. The initial soluble solid content of lime juice was 7.6 Brix. Results showed that soluble solid content of lime juice increased as cooling medium temperature decreased while scraper blade rotational speed increased. It was also found that the processing condition with -18˚C cooling medium temperature and 150 rpm rotational speed of the scraper blade was the best among all studied conditions, although the loss of the soluble solids with ice crystals during ice separation was relatively high at 35%.

    Full Text Available Lactobacillus casei ATCC 393 was employed as a fermentative organism to convert sugars from date juice into lactic acid. Both glucose and fructose in date juice were fermented directly without any pretreatment. The influences of supplementation of yeast extract and date juice concentration on some fermentation parameters, such as: cell growth rate, sugar conversion, productivity and yield, were investigated using this bacterium in batch fermentation. The results showed that by adding yeast extract about 20g/l in a date juice medium, the maximum specific growth rate of bacteria (μm enhanced from 0.1229 to 0.1819 g/l. Meanwhile, increasing date juice concentration from 86.6942 to 158.9181 and 229.5367 g/l enhanced the μm from 0.1819 to 0.2107 and 0.1916 g/l, respectively. It indicated that the optimum value for μm is 0.2107 g/l in this concentration range. In the date juice concentration of 158.9181 g/l, the optimum lactic acid can be produced is 117.8301 g/l with yield of 92.685% for 48 h.

  14. NSAID prescribing precautions.

    Science.gov (United States)

    Risser, Amanda; Donovan, Deirdre; Heintzman, John; Page, Tanya

    2009-12-15

    Nonsteroidal anti-inflammatory drugs (NSAIDs) are commonly used, but have risks associated with their use, including significant upper gastrointestinal tract bleeding. Older persons, persons taking anticoagulants, and persons with a history of upper gastrointestinal tract bleeding associated with NSAIDs are at especially high risk. Although aspirin is cardioprotective, other NSAIDs can worsen congestive heart failure, can increase blood pressure, and are related to adverse cardiovascular events, such as myocardial infarction and ischemia. Cyclooxygenase-2 inhibitors have been associated with increased risk of myocardial infarction; however, the only cyclooxygenase-2 inhibitor still available in the United States, celecoxib, seems to be safer in this regard. Hepatic damage from NSAIDs is rare, but these medications should not be used in persons with cirrhotic liver diseases because bleeding problems and renal failure are more likely. Care should be used when prescribing NSAIDs in persons taking anticoagulants and in those with platelet dysfunction, as well as immediately before surgery. Potential central nervous system effects include aseptic meningitis, psychosis, and tinnitus. Asthma may be induced or exacerbated by NSAIDs. Although most NSAIDs are likely safe in pregnancy, they should be avoided in the last six to eight weeks of pregnancy to prevent prolonged gestation from inhibition of prostaglandin synthesis, premature closure of the ductus arteriosus, and maternal and fetal complications from antiplatelet activity. Ibuprofen, indomethacin, and naproxen are safe in breastfeeding women. Care should be taken to prevent accidental NSAID overdose in children by educating parents about correct dosing and storage in childproof containers.

    Vukosavljević Predrag

    2006-01-01

    Full Text Available A change of anthocyanins under different conditions of enzymatic treatments, clarification and concentration was determined. A pectin preparation Klerzyme®120, manufactured by DSM, France, specific for "sour fruits" with pH below 3.2, was used for maceration and depectinization. Experiments were carried out by a laboratory hydraulic press. Raw raspberry juice was clarified either by membranes separation processes or by traditional treatments using gelatin and bentonite. For microfiltration and ultrafiltration processes, membrane cut-off should not be below 30,000 g/mol to prevent any color loss. Experiments with membrane separations processes were carried out with five different membranes. A raw depectinized raspberry juice was clarified by cross-flow microfiltration and ultrafiltration using ceramic tubular membranes and hollow fiber polymeric membranes of a molecular weight cut-off of 300, 50 and 30 kg /mol or with a mean pore size of 0.2 urn in the case of microfiltration. Fruit juice concentrations were carried out by a laboratory equipment for vacuum evaporation. Extraction yield by a laboratory hydraulic press was the same in case of single-stage maceration and two-stage maceration. However, due to a lower viscosity, it was observed that single-stage process provides raspberry juice with more color and high efficiency of extraction. It was noticed that thermal breaks of raspberry pulp provide juice containing more total anthocyanins. The clarification using gelatin and bentonite removed about 50% total anthocyanins, while a clarification by a cross-flow ultrafiltration using Carbosep M9, M8 and M7 membranes achieved the highest level of color loss. Total color loss after concentration was 70%. The best results in color protection were observed by a microfiltration through Kerasep membrane, due to its relatively large pores (0.2μm. .

    Full Text Available Background. The interest in potato juice as a therapeutic agent goes back to the 19th century but its application was not supported by any knowledge about biological activity of this raw material. Factors restricting the medical application of potato juice include its inattractive sensory and functional properties. The aim of the presented investigations was preliminary evaluation of the biological activity of potato juice and the impact on it of some technological operations such as: cryoconcentration and hydrolysis in a membrane reactor. Material and methods. Experiments comprised investigations of antioxidative potentials of fresh potato juice, products of its processing as well as fractions separated because of the size of their molecules using, for this purpose, Folin-Ciocalteu methods and reactions with the ABTS cation radical. Results. The value of the antioxidative potential of fresh potato juice determined by means of the ABTS reagent corresponded to approximately 330 μmol/100 g which is in keeping with literature data. As a result of the cryoconcentration process, the value determined by the Folin-Ciocalteu method was found to increase only slightly whereas the value determined by means of the ABTS reagent almost tripled. The antioxidative potential was found to grow even more strongly in the case of the application of both methods when the process of enzymatic hydrolysis was employed. The total of 5 protein fractions of molecular masses ranging from 11 000 Da to over 600 000 Da, as well as an organic non-protein fraction of the molecular mass of 600 Da, were obtained as a result of the performed separation. All the examined fractions exhibited antioxidative activities. The highest values determined by the Folin-Ciocalteu method were recorded for the protein fraction of 80 000 Da mean molecular mass, while using the ABTS reagent – for the organic, non-protein fraction. Conclusions. Potato juice possesses antioxidative activity which

    Full Text Available Abstract Background Atherosclerosis which results from gradual deposition of lipids in medium and large arteries is a leading cause of mortality worldwide. The objective of this study was to determine the effect of apple juice on some risk factors of atherosclerosis and on the development of atherosclerosis in rabbits fed a high-cholesterol diet. Methods Thirty two male rabbits were randomly divided into four groups: normal diet, high cholesterol diet (%1 cholesterol, 1% cholesterol supplemented with 5 ml apple juice (low dose and 1% cholesterol supplemented with 10 ml apple juice (high dose for 2 month. The C-reactive protein (CRP, nitrite, nitrate, fibrinogen, total cholesterol(TC and factor VII were measured before the experiment and by the end of period. At the end of study, fatty streak formation in right and left coronary arteries were determined using Chekanov method in all groups. Results Both doses of apple juice significantly were decreased TC, TG, CRP, fibrinogen, factor VII levels, atherosclerotic lesion in right and left coronary arteries and increased nitrite and nitrate compared to cholesterolemic diet. Also using 10 ml apple juice caused significant reduce in LDL-C and increase HDL-C, but 5 ml apple juice did not change these factors. Significant differences were observed between 5 and 10 ml apple juice groups by LDL-C. No significant difference was found between 5 and 10 ml apple juice groups with regard to CRP, nitrite, nitrate, fibrinogen, factor VII, TG, HDL-C and TC concentrations. Conclusion Apple juice can effectively prevent the progress of atherosclerosis. This is likely due to antioxidant and anti-inflammatory effect of apple juice.

  6. Impact of panchratna juice in the management of diabetes mellitus: Fresh vs. processed product

    Full Text Available Many of the plant sources have excellent nutrient and non-nutrient properties which can be exploited to manage clinical conditions. The current study was undertaken to assess the impact of panchratna juice (Amla, Tulsi, Ginger, Mint and Turmeric in the management of type 2 diabetes mellitus subjects. A total of 55 stable type 2 diabetics were enrolled from pathology laboratories and were given either fresh panchratna juice (n = 15 for 45 days or processed panchratna juice (n = 20 for 90 days and compared with diabetic controls (n = 20. Anthropometric profile, glycemic status and lipid profile were assessed on all the subjects at baseline, 45 days and 90 days. Students t test, paired t test and ANOVA were applied using Microsoft Excel. The results indicated that fresh panchratna juice or processed panchratna juice supplementation for long-term did not have any significant impact on the glycemic and lipemic status of diabetic subjects. Thus, the protective effects are lost with processing, and therefore, these plant sources should be consumed in their natural form.

    The aim of the study was to evaluate the adhesion abilities of the acetic acid bacterium Asaia bogorensis to glass and polystyrene in the presence of American cranberry (Vaccinium macrocarpon) juice. The strain of A. bogorensis used was isolated from spoiled commercial fruit-flavored drinking water. The cranberry juice was analyzed for polyphenols, organic acids, and carbohydrates using high-performance liquid chromatography and liquid chromatography-mass spectrometry techniques. The adhesive abilities of bacterial cells in culture medium supplemented with cranberry juice were determined using luminometry and microscopy. The viability of adhered and planktonic bacterial cells was determined by the plate count method, and the relative adhesion coefficient was calculated. This strain of A. bogorensis was characterized by strong adhesion properties that were dependent upon the type of surface. The highest level of cell adhesion was found on the polystyrene. However, in the presence of 10% cranberry juice, attachment of bacterial cells was three times lower. Chemical analysis of juice revealed the presence of sugars, organic acids, and anthocyanins, which were identified as galactosides, glucosides, and arabinosides of cyanidin and peonidin. A-type proanthocyanidins responsible for the antiadhesion properties of V. macrocarpon also were detected.

    Full Text Available The use of other inducers as substitutes for pectin was studied aiming to reduce the production costs of pectic enzymes. The effects of sugar-cane juice on the production of pectin lyase (PL and polygalacturonase (PG by Penicillium griseoroseum were investigated. The fungus was cultured in a mineral medium (pH 6.3 in a rotary shaker (150 rpm for 48 h at 25oC. Culture media were supplemented with yeast extract and sucrose or sugar-cane juice. Sugar-cane juice added singly to the medium promoted higher PL activity and mycelial dry weight when compared to pectin and the use of sugar-cane juice and yeast extract yielded levels of PG activity that were similar to those obtained with sucrose-yeast extract or pectin. The results indicated that, even at low concentrations, sugar-cane juice was capable of inducing pectin lyase and polygalacturonase with no cellulase activity in P. griseoroseum.

  9. Inappropriate prescribing in the elderly.

    2012-02-03

    BACKGROUND AND OBJECTIVE: Drug therapy is necessary to treat acute illness, maintain current health and prevent further decline. However, optimizing drug therapy for older patients is challenging and sometimes, drug therapy can do more harm than good. Drug utilization review tools can highlight instances of potentially inappropriate prescribing to those involved in elderly pharmacotherapy, i.e. doctors, nurses and pharmacists. We aim to provide a review of the literature on potentially inappropriate prescribing in the elderly and also to review the explicit criteria that have been designed to detect potentially inappropriate prescribing in the elderly. METHODS: We performed an electronic search of the PUBMED database for articles published between 1991 and 2006 and a manual search through major journals for articles referenced in those located through PUBMED. Search terms were elderly, inappropriate prescribing, prescriptions, prevalence, Beers criteria, health outcomes and Europe. RESULTS AND DISCUSSION: Prescription of potentially inappropriate medications to older people is highly prevalent in the United States and Europe, ranging from 12% in community-dwelling elderly to 40% in nursing home residents. Inappropriate prescribing is associated with adverse drug events. Limited data exists on health outcomes from use of inappropriate medications. There are no prospective randomized controlled studies that test the tangible clinical benefit to patients of using drug utilization review tools. Existing drug utilization review tools have been designed on the basis of North American and Canadian drug formularies and may not be appropriate for use in European countries because of the differences in national drug formularies and prescribing attitudes. CONCLUSION: Given the high prevalence of inappropriate prescribing despite the widespread use of drug-utilization review tools, prospective randomized controlled trials are necessary to identify useful interventions.

    Full Text Available Watermelon is a natural product that contains high level of antioxidants and may prevent oxidative damage in tissues due to free radical generation following an exposure to ionizing radiation. The present study aimed to investigate the radioprotective effects of watermelon (Citrullus lanatus (Thunb. Matsum. and Nakai juice against oxidative damage induced by low dose X-ray exposure in mice. Twelve adult male ICR mice were randomly divided into two groups consisting of radiation (Rx and supplementation (Tx groups. Rx received filtered tap water, while Tx was supplemented with 50% (v/v watermelon juice for 28 days ad libitum prior to total body irradiation by 100 μGy X-ray on day 29. Brain, lung, and liver tissues were assessed for the levels of malondialdehyde (MDA, apurinic/apyrimidinic (AP sites, glutathione (GSH, and superoxide dismutase (SOD inhibition activities. Results showed significant reduction of MDA levels and AP sites formation of Tx compared to Rx (P<0.05. Mice supplemented with 50% watermelon juice restore the intracellular antioxidant activities by significantly increased SOD inhibition activities and GSH levels compared to Rx. These findings may postulate that supplementation of 50% watermelon (Citrullus lanatus (Thunb. Matsum. and Nakai juice could modulate oxidative damage induced by low dose X-ray exposure.

    Adverse drug interactions due to grapefruit juice are well known prompting warnings even in drug labels. Similar issues have not been reported for clementines and available data is scarce, despite of genetic descent. We observed substantially increased tacrolimus trough concentrations in a renal transplant patient consuming high clementine amounts and, thus, scrutinised the effects of clementine juice on drug metabolism and drug transporters in vitro and compared it to the effects of mandarin and grapefruit juice. All citrus juices profoundly induced several drug transporters and drug metabolising enzymes, whereas the effects of grapefruit juice were most pronounced (e.g. 156-fold and 34-fold induction of cytochrome P450 (CYP) 3A4 mRNA by grapefruit juice and clementine juice, respectively). However, the juices also inhibited e.g. CYP3A4, raising the question which effect prevails in vivo. Using an enzymatic activity assay, we demonstrated that at least in vitro CYP3A4 inhibition prevails for both grapefruit and clementine juice, whereas for CYP1A2 induction appears to predominate. Thus, inhibition of CYP3A4 is presumably the underlying reason for the observed increase in the concentrations of the CYP3A4 substrate tacrolimus in the patient. Taken together, our data indicate that clementine juice as well as grapefruit juice and to a lesser extent also mandarin juice can induce several important drug metabolising enzymes and drug transporters, but also inhibit some of these proteins. Our data indicate that clementine juice similar to grapefruit juice bears the potential for profound interactions with drugs potentially leading to adverse drug effects e.g. through over-exposure to CYP3A4 substrates.

    The consumption of fresh nopal cactus juice is widely popular among health-conscious consumers in Mexico. The juice is prepared from fresh cladodes that have only been rinsed with tap water and are not subjected to a pasteurization or terminal bacterial reduction process. The aim of this study was to evaluate the microbial quality of commercially available fresh juices (n = 162) made with nopal in Texcoco, State of Mexico, during the summer and spring season. Standard microbiological methods, the PCR technique and the serological method were used for isolation and identification of bacteria. All samples contained total coliforms and 91% were positive for Escherichia coli. Although total coliforms and E. coli were detected throughout the study, their populations were significantly lower (p nopal juices is unacceptable due to its health significance. The information generated in this study is relevant for human health risk assessment associated with the consumption of unpasteurized nopal juices and potential interventions to minimize pathogen contamination.

    The antiatherogenic properties of pomegranate juice (PJ) were attributed to its antioxidant potency and to its capacity to decrease macrophage oxidative stress, the hallmark of early atherogeneis. PJ polyphenols and sugar-containing polyphenolic anthocyanins were shown to confer PJ its antioxidant capacity. In the present study, we questioned whether PJ simple or complex sugars contribute to the antioxidative properties of PJ in comparison to white grape juice (WGJ) sugars. Whole PJ decreased cellular peroxide levels in J774A.1 macrophage cell-line by 23% more than PJ polyphenol fraction alone. Thus, we next determined the contribution of the PJ sugar fraction to the decrease in macrophage oxidative state. Increasing concentrations of the PJ sugar fraction resulted in a dose-dependent decrement in macrophage peroxide levels, up to 72%, compared to control cells. On the contrary, incubation of the cells with WGJ sugar fraction at the same concentrations resulted in a dose-dependent increment in peroxide levels by up to 37%. The two sugar fractions from PJ and from WGJ showed opposite effects (antioxidant for PJ and pro-oxidant for WGJ) also in mouse peritoneal macrophages (MPM) from control as well as from streptozotocin-induced diabetic Balb/C mice. PJ sugar consumption by diabetic mice for 10 days resulted in a small but significant decrement in their peritoneal macrophage total peroxide levels and an increment in cellular glutathione content, compared to MPM harvested from control diabetic mice administrated with water. In contrast, WGJ sugar consumption by diabetic mice resulted in a 22% increment in macrophage total peroxide levels and a 45% decrement in cellular glutathione content. Paraoxonase 2 activity in macrophages increases under oxidative stress conditions. Indeed, macrophage paraoxonase 2 activity was decreased after PJ sugars supplementation, but increased after WGJ sugars supplementation. We conclude that PJ sugar fraction, unlike WGJ sugar fraction

    Lactobacillus plantarum BET003 isolated from Momordica charantia fruit was used to ferment its juice. Momordica charantia fresh juice was able to support good growth of the lactic acid bacterium. High growth rate and cell viability were obtained without further nutrient supplementation. In stirred tank reactor batch fermentation, agitation rate showed significant effect on specific growth rate of the bacterium in the fruit juice. After the fermentation, initially abundant momordicoside 23-O-β-Allopyranosyle-cucurbita-5,24-dien-7α,3β,22(R),23(S)-tetraol-3-O-β-allopyranoside was transformed into its corresponding aglycone in addition to the emergence of new metabolites. The fermented M. charantia juice consistently reduced glucose production by 27.2%, 14.5%, 17.1% and 19.2% at 15-minute intervals respectively, when compared against the negative control. This putative anti-diabetic activity can be attributed to the increase in availability and concentration of aglycones as well as other phenolic compounds resulting from degradation of glycosidic momordicoside. Biotransformation of M. charantia fruit juice via lactic acid bacterium fermentation reduced its bitterness, reduced its sugar content, produced aglycones and other metabolites as well as improved its inhibition of α-glucosidase activity compared with the fresh, non-fermented juice.

    1999-02-01

    The creation of The Medical Products (Prescription by Nurses, etc.) Act 1992 has been generally welcomed by the nursing profession. This article seeks to introduce a note of scepticism about the assumed motivations for its introduction through an analysis of various legal, ethical, economic and political dimensions. In reviewing the position of nursing vis-à-vis medicine it is argued that one of the ways that nursing has sought to improve its professional position is to take on work previously done by doctors, and nurse prescribing can be seen in the context of the concurrent de-regulation of medicines, allowing greater access to medicines and therefore greater consumer choice. This de-regulation stems from the liberation ideology of the previous Conservative government. Viewed in this way nurse prescribing, particularly with reference to the limited nature of the nursing formulary, can be seen to be anomalous. In the light of this analysis, the reasons generally put forward (notably in the Crown Report 1989) for the introduction of nurse prescribing could be seen to be peripheral to its real purpose. It is argued that the most convincing reasons for its introduction relate to the medical profession as a social institution. It is proposed that the three primary aims behind the introduction of nurse prescribing are: the saving of money; the transfer of routine medical work to nursing; and a challenge to the professional monolith of medicine.

    Full Text Available Production and preservation of Passion Fruit Juice was examined to reduce the spoilage and to increase the shelf life of the juice using chemical preservatives. The preservation of the juice was carried out using sugar, benzoic acid, citric and a combination of citric and benzoic acid under room temperature.The result revealed that the juice maintained its color, aroma and tastes for at least one month when 30% benzoic acid was used as preservative. This happens to be the best among all. The juice under other preservation like 4% sugar went bad after three days, while that of 4% citric acid maintained its qualities for one week and some days, but thereafter the aroma started to fade. The combination of 3% benzoic acid and 4% citric acid maintained the qualities of the juice fairly between two to three weeks. The alcoholic content was also estimated and it was discovered that the juice containing citric acid and sugar has the highest percentage of alcohol. The preservation used also altered the pH so that it is impossible for pathogens to exist at such a low pH environment.

    The main protective role of antioxidants in the progression of atherosclerosis has been shown in some studies. Therefore, this project evaluated the effects of Citrus aurantifolia (Christm) juice and peel on antioxidant activity and atherosclerosis progression in rabbits receiving a hypercholesterolemic diet. Forty white New Zealand male rabbits were randomly allocated to four groups. All groups were on hypercholesterolemic diet for two months. While the first group was considered as the hypercholesterolemic control, groups 2 and 3 (intervention groups) received 5 ml/day lime juice and 1 g/day dried lime peel powder, respectively. Group 4 was fed a normal diet (normal control). Before and after the study, weight was measured and a fasting blood specimen was taken from the rabbits. Serum lipids analyses and antioxidant activity evaluations were then performed. The rabbits' aorta and coronary arteries were separated and the presence of fatty streaks was studied. Comparing to the hypercholesterolemic control group (-25.2 ± 7.0), only the plasma total antioxidant capacity change was significantly more in rabbits supplemented with lime juice (16.3 ± 14.7) and peel (8.6 ± 7.1) (P = 0.008). The presence of fatty streaks in coronary arteries and aorta of the intervention groups [juice (0.2 ± 0.01); peel (0.0 ± 0.00)] was significantly decreased compared to the hypercholesterolemic control group (1.2 ± 0.4) (P Citrus aurantifolia peel and juice increase plasma antioxidant capacity in rabbits, and can thus prevent or decelerate the process of atherogenesis. However, lime peel is more effective than lime juice.

    2014-08-01

    Many athletes use dietary supplements, with use more prevalent among those competing at the highest level. Supplements are often self-prescribed, and their use is likely to be based on an inadequate understanding of the issues at stake. Supplementation with essential micronutrients may be useful when a diagnosed deficiency cannot be promptly and effectively corrected with food-based dietary solutions. When used in high doses, some supplements may do more harm than good: Iron supplementation, for example, is potentially harmful. There is good evidence from laboratory studies and some evidence from field studies to support health or performance benefits from appropriate use of a few supplements. The available evidence from studies of aquatic sports is small and is often contradictory. Evidence from elite performers is almost entirely absent, but some athletes may benefit from informed use of creatine, caffeine, and buffering agents. Poor quality assurance in some parts of the dietary supplements industry raises concerns about the safety of some products. Some do not contain the active ingredients listed on the label, and some contain toxic substances, including prescription drugs, that can cause health problems. Some supplements contain compounds that will cause an athlete to fail a doping test. Supplement quality assurance programs can reduce, but not entirely eliminate, this risk.

    Full Text Available Leaf of Adhatoda vasica ( Vasaka is an important drug of Ayurveda, prescribed as an expectorant. Quinazoline alkaloids present in the leaves are established as active principles. In Ayurveda, its leaf juice ( Vasa swarasa is incorporated in many formulations. Classical method for extracting the juice ( swarasa from the leaf is an elaborate process, which involves subjecting a bolus of crushed fresh leaf to heat followed by squeezing out the juice. Commercially, to prepare the juice of Vasaka , manufacturers have been adopting different methods other than the traditional method. In an effort to evaluate these modified processes phytochemically to identify the process which gives juice of the quality that is obtained by traditional method, in terms of its alkaloid content, we prepared the leaf juice by traditional Ayurvedic method, its modification by steaming of leaf to simulate the traditional method and other methods adopted by some manufacturers. These juice samples were evaluated for the total alkaloid content by spectrophotometric method and vasicine content by thin layer chromatography densitometric method using high performance thin layer chromatography. The high performance thin layer chromatography method was validated for precision, repeatability and accuracy. The total alkaloid content varied from 0.3 mg/ml to 5.93 mg/ml and that of vasicine content varied from 0.2 mg/ml to 5.64 mg/ml in the juice samples prepared by different methods. The present study revealed that steaming of fresh leaves under 15 lb pressure yielded same quantity of juice as the traditional bolus method (25 ml/100 g leaf and its total alkaloid content and vasicine content (4.05±0.12 and 3.46±0.06 mg/ml, respectively were very high when compared to the other methods, though the traditional method was found to give the best quality juice with highest amount of total alkaloids (5.93±0.55 mg/ml and vasicine (5.64±0.10 mg/ml content .

    Full Text Available Abstract Background Over 300 therapies have been proposed for premenstrual syndrome. To date there has been only one survey conducted in the UK of PMS treatments prescribed by GPs, a questionnaire-based study by the National Association of Premenstrual Syndrome in 1989. Since then, selective serotonin re-uptake inhibitors have been licensed for severe PMS/PMDD, and governmental recommendations to reduce the dosage of vitamin B6 (the first choice over-the-counter treatment for many women with PMS have been made. This study investigates the annual rates of diagnoses and prescribing patterns for premenstrual syndrome (1993–1998 within a computerised general practitioner database. Methods Retrospective survey of prescribing data for premenstrual syndrome between 1993–1998 using the General Practice Research Database for the West Midlands Region which contains information on 282,600 female patients Results Overall the proportion of women with a prescription-linked diagnosis of premenstrual syndrome has halved over the five years. Progestogens including progesterone were the most commonly recorded treatment for premenstrual syndrome during the whole study period accounting for over 40% of all prescriptions. Selective serotonin-reuptake inhibitors accounted for only 2% of the prescriptions in 1993 but rose to over 16% by 1998, becoming the second most commonly recorded treatment. Vitamin B6 accounted for 22% of the prescriptions in 1993 but dropped markedly between 1997 and 1998 to 11%. Conclusions This study shows a yearly decrease in the number of prescriptions linked to diagnoses for premenstrual syndrome. Progestogens including progesterone, is the most widely prescribed treatment for premenstrual syndrome despite the lack of evidence demonstrating their efficacy.

    The chemical composition of 30 samples of juices obtained from bergamot (Citrus bergamia Risso and Poit.) fruits is reported and compared to the genuineness parameters adopted by Association of the Industry of Juice and Nectars (AIJN) for lemon juice. It was found that the compositional differences between the two juices are distinguishable, although with difficulty. However, these differences are not strong enough to detect the fraudulent addition of bergamot juice to lemon juice. Instead, we found the high-performance liquid chromatography (HPLC) analysis of the flavanones naringin, neohesperidin, and neoeriocitrin, which are present in bergamot juice and practically absent in the lemon juice, is a convenient way to detect and quantify the fraudulent addition of bergamot juice. The method has been validated by calculating the detection and quantification limits according to Eurachem procedures. Employing neoeriocitrin (detection limit = 0.7 mg/L) and naringin (detection limit = 1 mg/L) as markers, it is possible to detect the addition of bergamot juice to lemon juice at the 1% level. When using neohesperidin as a marker (detection limit = 1 mg/L), the minimal percentage of detectable addition of bergamot juice was about 2%. Finally, it is reported that the pattern of flavonoid content of the bergamot juice is similar to those of chinotto (Citrus myrtifolia Raf) and bitter orange (Citrus aurantium L.) juices and that it is possible to distinguish the three kinds of juices by HPLC analysis.

    Magnetic resonance cholangiopancreatography (MRCP) is commonly performed in the evaluation of known or suspected pancreaticobiliary disease in children. The administration of a negative oral contrast agent can improve the quality of the examination without significant additional cost. We describe our experience with certain brands of acai juice, blueberry juice and pineapple juice as negative oral contrast agents in children. We believe these fruit juices are safe, palatable and may improve MRCP image quality. (orig.)

    This study evaluated and compared in vitro the morphology and mineral composition of dental enamel after erosive challenge in gastric juice and orange juice. Human enamel specimens were submitted to erosive challenge using gastric juice (from endoscopy exam) (n = 10), and orange juice (commercially-available) (n = 10), as follows: 5 min in 3 mL of demineralization solution, rinse with distilled water, and store in artificial saliva for 3 h. This cycle was repeated four times a day for 14 days. Calcium (Ca) loss after acid exposure was determined by atomic emission spectroscopy. The presence of carbonate (CO) and phosphate (PO) in the specimens was evaluated before and after the erosive challenge by FT-Raman spectroscopy. Data were tested using t-tests (P enamel was observed in scanning electron microscopy (SEM). The mean loss of Ca was: 12.74 ± 3.33 mg/L Ca (gastric juice) and 7.07 ± 1.44 mg/L Ca (orange juice). The analysis by atomic emission spectroscopy showed statistically significant difference between erosive potential of juices (P = 0.0003). FT-Raman spectroscopy found no statistically significant difference in the ratio CO/PO after the erosive challenge. The CO/PO ratios values before and after the challenge were: 0.16/0.17 (gastric juice) (P = 0.37) and 0.18/0.14 (orange juice) (P = 0.16). Qualitative analysis by SEM showed intense alterations of enamel surface. The gastric juice caused more changes in morphology and mineral composition of dental enamel than orange juice. The atomic emission spectroscopy showed to be more suitable to analyze small mineral loss after erosive challenge than FT-Raman. Copyright © 2011 Wiley Periodicals, Inc.

    2013-06-01

    Full Text Available China is the first country in the world in which apple juice is produced and exited and the main producing area is concentrated in the north of China. Some domestic companies which export apple juice are founded. China’s apple juice, mainly exported to USA, Japan and the Europe, has a strong international competitiveness. However, due to the breed and raw material, Chinese apple juice export faces some challenge, like the loss happening in the transport process. The objective of this study is to research China's apple juice export situation and problem using the comparative analysis method. To cut down the loss, this study is trying to offer a relative scientific research for fruit juice industry by analyzing how temperature and concentration influence on thermal conductivity of apple juice, affecting the whole juice industry. It is with great significance to solve the realistic problems and promote China apple juice industry and its international trade.

  1. Potential interaction between pomegranate juice and warfarin.

    Science.gov (United States)

    Komperda, Kathy E

    2009-08-01

    To my knowledge, no published reports have described an interaction between pomegranate juice and warfarin. Investigators from previous animal and in vitro studies have reported a potential for pomegranate juice to inhibit metabolism involving the cytochrome P450 system, an effect that could translate into a clinical drug-diet interaction with warfarin. This case report describes a 64-year-old Caucasian woman who was treated with warfarin for recurrent deep vein thrombosis. She had been receiving a relatively stable dosage of warfarin 4 mg/day for several months, with stable international normalized ratios (INRs). During that time, the patient was consuming pomegranate juice 2-3 times/week. She stopped drinking the juice, and her INRs became subtherapeutic. Her dosage of warfarin was increased to maintain therapeutic anticoagulation. No rechallenge with pomegranate juice was performed. Use of the Drug Interaction Probability Scale indicated a possible relationship between the patient's subtherapeutic INR and the pomegranate juice. Although this potential interaction needs to be explored further, clinicians should be aware of the interaction and thoroughly interview and closely monitor their patients who are receiving warfarin.

    A single glass of grapefruit juice can improve the oral bioavailability of a drug thus either increasing its efficacy or enhancing its adverse effects particularly if the therapeutic index is narrow. Grapefruit juice acts by inhibiting presystemic drug metabolism mediated by CYP P450 3A4 in the small bowel and this interaction would appear to be more relevant if the CYP 3A4 content is high and the drug has a strong first pass degradation. Intestinal P-glycoprotein may also be affected by grapefruit juice. The compounds responsible for this food-drug interaction have not as yet been identified but this phenomenon could result from a complex synergy between flavonoids (naringin, naringenin), furanocoumarins (6',7'-dihydroxybergamottin, bergamottin) and sesquiterpen (nootkatone). In our study, we report the mechanisms of action of grapefruit juice and the interactions between grapefruit juice and 42 drugs; to date, only 12 drugs showed no interaction. Taking these results into consideration, patients should be educated about grapefruit juice intake with medication.

Material and Methods: a number of 349 subjects (149 pharmacists and 200 doctors answered a survey about the perception of drug dispensing in Romania. Variables like age, work environment (urban, rural, length of employment were taken into account. Results: When prescribing a treatment, 93% of doctors follow the standard treatment protocol for the given diagnosis and 93,5% of them are declaring that personal resources are the main source for training while the percent appreciated by pharmacists is evaluated to 65,78%. A total of 50% of doctors are considering other criteria than the treatment when prescribing a drug (financial contribution for the patient or National Health Insurance House. A total of 59% of doctors are recommending overthe-counter products while pharmacists consider that is happening in more than 70% of the cases. Conclusions: There are differences of opinion between doctors and pharmacists regarding doctor’s practices of prescribing drugs to their patients, like: kinds of sponsorship for the continuing education, the relationship with the pharmaceutical representative or the frequency of prescribing over-the-counter products or supplements when they are recommending a certain treatment.

    Anthocyanins can contribute to human health through preventing a variety of diseases. The uptake of these compounds from food and the parameters determining uptake efficiency within the human body are still poorly understood. Here we have employed a Caco-2 cell based system to investigate the transport of key antioxidant food components from sour cherry (Prunus cerasus L.) across the intestinal epithelial barrier. Anthocyanins and (-)-epicatechin were supplied in three contrasting matrices: fruit, processed fruit cherry juice, and polyphenolic fractions obtained by solid-phase extraction. Results show that both compound types behave differently. Fruit or juice matrices display comparable transport across the epithelial cell layer. The juice supplements sucrose and citric acid, which are regularly added to processed foods, have a positive effect on stability and transport. Polyphenolic fractions display a lower transport efficiency, relative to that of the fruit or juice, indicating the importance of food matrix components for intestinal absorption of polyphenols.

    2015-01-01

    The association between the consumption of pure (100%) fruit juice (PFJ) and human health is uncertain. The current review summarizes data published between 1995 and 2012 related to PFJ with a focus on juices that are widely available and studied in forms representing native juice without supplemental nutrients or enhanced phytochemical content. The effects of apple, cranberry, grape, grapefruit, orange, and pomegranate PFJ intake on outcomes linked to cancer, cardiovascular disease, cognition, hypertension, inflammation, oxidation, platelet function, urinary tract infection, and vascular reactivity are reviewed. Implications for bodyweight regulation are also addressed. The collective data are provocative although challenges and unanswered questions remain. There are many plausible mechanisms by which PFJ might be protective, and investigation of its effects on human health and disease prevention must remain an active area of research.

  11. Inappropriate prescribing: criteria, detection and prevention.

    O'Connor, Marie N

    2012-06-01

    Inappropriate prescribing is highly prevalent in older people and is a major healthcare concern because of its association with negative healthcare outcomes including adverse drug events, related morbidity and hospitalization. With changing population demographics resulting in increasing proportions of older people worldwide, improving the quality and safety of prescribing in older people poses a global challenge. To date a number of different strategies have been used to identify potentially inappropriate prescribing in older people. Over the last two decades, a number of criteria have been published to assist prescribers in detecting inappropriate prescribing, the majority of which have been explicit sets of criteria, though some are implicit. The majority of these prescribing indicators pertain to overprescribing and misprescribing, with only a minority focussing on the underprescribing of indicated medicines. Additional interventions to optimize prescribing in older people include comprehensive geriatric assessment, clinical pharmacist review, and education of prescribers as well as computerized prescribing with clinical decision support systems. In this review, we describe the inappropriate prescribing detection tools or criteria most frequently cited in the literature and examine their role in preventing inappropriate prescribing and other related healthcare outcomes. We also discuss other measures commonly used in the detection and prevention of inappropriate prescribing in older people and the evidence supporting their use and their application in everyday clinical practice.

    Blood pressure is the force of blood against artery walls. It is measured in millimeters of mercury (mm Hg and recorded as two numbers: systolic pressure (as the heart contracts over diastolic pressure (as the heart relaxes between beats. High blood pressure (hypertension is defined as chronically elevated high blood pressure, with systolic blood pressure (SBP of 140 mm Hg or greater, and diastolic blood pressure (DBP of 90 mm Hg or greater. High blood pressure (HBP, smoking, abnormal blood lipid levels, obesity and diabetes are risk factors for coronary heart disease, the leading cause of death in the US. Lifestyle modifications such as engaging in regular physical activity, quitting smoking and eating a healthy diet (limiting intake of saturated fat and sodium and increasing consumption of fiber, fruits and vegetables are advocated for the prevention, treatment, and control of HBP. As multiple factors influence blood pressure, the effects of each factor are typically modest, particularly in normotensive subjects, yet the combined effects can be substantial. Nutrition plays an important role in influencing blood pressure. Orange juice should be included as part of any low sodium diet and/or any blood pressure reducing eating plan, as it is sodium free, fat-free and can help meet recommended levels of potassium intake that may contribute to lower BP.

    2011-03-01

    The influence of patient expectations and demands on the decisions of prescribers in general practice has been associated with irrational prescribing and lack of evidence-based practice. However, to our knowledge, no one has investigated patient pressure to prescribe in secondary care. To investigate the influences on hospital prescribers' decisions by exploring what they found uncomfortable when prescribing. Qualitative interviews with 48 prescribers of varying seniority from 4 hospitals were conducted. Interviews were based on the critical incident technique, and prescribers were asked, before an interview, to remember any uncomfortable prescribing decisions that they had made; these were then discussed in detail during an interview. This approach allowed the interviewer to explore the more general influences on the decision to prescribe. Interviews were tape recorded and transcribed verbatim. A grounded theory approach to data analysis was taken. Prescribers discussed various factors that could provoke feelings of discomfort when prescribing. Pressure on the prescribing decision from patients, relatives, or carers was a major theme, and more than half of interviewees discussed discomfort caused by such perceived pressure on the prescribing decision. How prescribers dealt with this pressure varied with seniority and the type of relationship that they had fostered with the patient. Nearly half of all incidents of patient pressure resulted in the patient being prescribed the medication they requested. Yet, many of these requests were deemed inappropriate by the prescriber. Their reasons for capitulation varied but included maintaining a good prescriber-patient relationship and avoiding conflict in the wider health care team. Pressure from patients, relatives, or carers was an uncomfortable influence on these hospital prescribers' prescribing decisions. Increasingly consumer-driven health care will intensify these issues in the future. We advocate further research

    Aloe vera, a common ingredient in cosmetics, is increasingly being consumed as a beverage supplement. Although consumer interest in aloe likely stems from its association with several health benefits, a concern has also been raised by a National Toxicology Program Report that a nondecolorized whole leaf aloe vera extract taken internally by rats was associated with intestinal mucosal hyperplasia and ultimately malignancy. We tested a decolorized whole leaf (DCWL) aloe vera, treated with activated charcoal to remove the latex portion of the plant, for genotoxicity in bacteria, acute/subacute toxicity in B6C3F1 mice, and subchronic toxicity in F344 rats. We found this DCWL aloe vera juice to be nongenotoxic in histidine reversion and DNA repair assays. Following acute administration, mice exhibited no adverse signs at 3- or 14-day evaluation periods. When fed to male and female F344 rats over 13 weeks, DCWL aloe led to no toxicity as assessed by behavior, stools, weight gain, feed consumption, organ weights, and hematologic or clinical chemistry profiles. These rats had intestinal mucosal morphologies-examined grossly and microscopically-that were similar to controls. Our studies show that oral administration of this DCWL aloe juice has a different toxicology profile than that of the untreated aloe juice at exposures up to 13 weeks.

Standard microbiological methods, the PCR technique and the serological method were used for isolation and identification of bacteria. All samples contained total coliforms and 91% were positive for Escherichia coli. Although total coliforms and E. coli were detected throughout the study, their populations were significantly lower (p < 0.05 in winter and spring, respectively. Citrobacter youngae was found in 20% of the samples, an unidentified species of Citrobacter in 10%, C. freundii and Proteus mirabilis in 3%, and Salmonella Javiana in 1%. The presence of these microorganisms, especially Salmonella, in the nopal juices is unacceptable due to its health significance. The information generated in this study is relevant for human health risk assessment associated with the consumption of unpasteurized nopal juices and potential interventions to minimize pathogen contamination.

    The consumption of fresh nopal cactus juice is widely popular among health-conscious consumers in Mexico. The juice is prepared from fresh cladodes that have only been rinsed with tap water and are not subjected to a pasteurization or terminal bacterial reduction process. The aim of this study was to evaluate the microbial quality of commercially available fresh juices (n = 162) made with nopal in Texcoco, State of Mexico, during the summer and spring season. Standard microbiological methods, the PCR technique and the serological method were used for isolation and identification of bacteria. All samples contained total coliforms and 91% were positive for Escherichia coli. Although total coliforms and E. coli were detected throughout the study, their populations were significantly lower (p < 0.05) in winter and spring, respectively. Citrobacter youngae was found in 20% of the samples, an unidentified species of Citrobacter in 10%, C. freundii and Proteus mirabilis in 3%, and Salmonella Javiana in 1%. The presence of these microorganisms, especially Salmonella, in the nopal juices is unacceptable due to its health significance. The information generated in this study is relevant for human health risk assessment associated with the consumption of unpasteurized nopal juices and potential interventions to minimize pathogen contamination.

    2014-01-01

    There has been an increased consumption of fruit juice as consumers have become aware of the nutritional and health benefits of fruit juices. This increased consumption goes together with the growth of varieties of fruit juices and beverages offered for sale. Among these products is roselle (Hibiscus sabdariffa L.) juice, or drink, which is a good source of anthocyanins, vitamins (thiamine, riboflavin, niacin, ascorbic acid) and minerals (Ca, P, Fe). In addition, roselle is also used as flavo...

  9. Liquid chromatographic determination of naringin and neohesperidin as a detector of grapefruit juice in orange juice.

    1988-01-01

    Naringin/neohesperidin ratios can be used to differentiate orange juice which may contain added grapefruit juice from orange juice which may include juices from other naringin-containing cultivars. The naringin/neohesperidin ratios in juice vary from 14 to 83 in grapefruit (C. grandis) and from 1.3 to 2.5 in sour orange (C. aurantium) cultivars; the ratio is always less than 1 for the K-Early tangelo. Concentrations of both naringin and neohesperidin can be determined in orange juice by using a single liquid chromatographic isocratic reverse-phase system with a C-18 column. The detection limit for both compounds is 1 ppm with a linear working range to 500 ppm. Concentration relative standard deviations range from 0.47 to 1.06% for naringin and from 0.4 to 1.27% for neohesperidin. Naringin and neohesperidin recoveries ranged from 93 to 102% at concentrations of 5 and 50 ppm. Naringin values from blind duplicate samples of orange/grapefruit juice blends could be duplicated to +/- 3%.

    Rigid lenses have been fitted less since the introduction of soft lenses nearly 40 years ago. Data that we have gathered from annual contact lens fitting surveys conducted in Australia, Canada, Japan, the Netherlands, Norway, the UK and the USA between 2000 and 2008 facilitate an accurate characterization of the pattern of the decline of rigid lens fitting during the first decade of this century. There is a trend for rigid lenses to be utilized primarily for refitting those patients who are already successful rigid lens wearers-most typically older females being refit with higher Dk materials. Rigid lenses are generally fitted on a full-time basis (four or more days of wear per week) without a planned replacement schedule. Orthokeratology is especially popular in the Netherlands, but is seldom prescribed in the other countries surveyed.

    2017-08-01

    We introduce a method to determine whether a given generalized quantum measurement is isolated or if it belongs to a family of measurements having the same prescribed symmetry. The technique proposed reduces to solving a linear system of equations in some relevant cases. As a consequence, we provide a simple derivation of the maximal family of symmetric informationally complete positive operator-valued measure SIC-POVM in dimension 3. Furthermore, we show that the following remarkable geometrical structures are isolated, so that free parameters cannot be introduced: (a) maximal sets of mutually unbiased bases in prime power dimensions from 4 to 16, (b) SIC-POVM in dimensions from 4 to 16, and (c) contextual Kochen-Specker sets in dimension 3, 4, and 6, composed of 13, 18, and 21 vectors, respectively.

    2012-02-03

    Inappropriate prescribing in older people is a common condition associated with significant morbidity, mortality, and financial costs. Medication use increases with age, and this, in conjunction with an increasing disease burden, is associated with adverse drug reactions. This review outlines why older people are more likely to develop adverse drug reactions and how common the problem is. The use of different tools to identify and measure the problem is reviewed. Common syndromes seen in older adults (eg, falling, cognitive impairment, sleep disturbance) are considered, and recent evidence in relation to medication use for these conditions is reviewed. Finally, we present a brief summary of significant developments in the recent literature for those caring for older people.

    Rocha, Maria V. P.; Souza, Maria C. M.; Benedicto, Sofia C. L.; Bezerra, Márcio S.; Macedo, Gorete R.; Saavedra Pinto, Gustavo A.; Gonçalves, Luciana R. B.

    In this work, the ability of biosurfactant production by Pseudomonas aeruginosa in batch cultivation using cashew apple juice (CAJ) and mineral media was evaluated. P. aeruginosa was cultivated in CAJ, which was supplemented with peptone (5.0 g/L) and nutritive broth. All fermentation assays were performed in Erlenmeyer flasks containing 300 mL, incubated at 30°C and 150 rpm. Cell growth (biomass and cell density), pH, and superficial tension were monitored vs time. Surface tension was reduced by 10.58 and 41% when P. aeruginosa was cultivated in nutrient broth and CAJ supplemented with peptone, respectively. These results indicated that CAJ is an adequate medium for growth and biosurfactant production. Best results of biosurfactant production were obtained when CAJ was supplemented with peptone.

    2010-03-24

    Inorganic copper compounds are not considered as synthetic fertilizers for apple trees as they are traditional fertilizers. Thus, they are used in organic farming for soil or foliar applications. The European Union is for health reasons interested in reducing copper in apple orchards. Because the fertilizer application rate affects the nutrition of apples, the applied copper might also be reflected in the copper concentration of apple juices. Thus, the determination of copper is of concern for investigating the application of copper-containing fertilizers. Samples of clarified apple juice commercially available in the European market were analyzed for their copper content. Prior to quantification by inductively coupled plasma-optical emission spectrometry, the juices were processed by a microwave-assisted digestion system using HNO(3). All samples were also measured directly after dilution with HNO(3). The copper concentrations measured using both methods were all below the limit of detection (17 microg/L).

    Full Text Available Peptic ulcer is the most prevalent gastrointestinal disease. Even though a wide range of drugs are available for the treatment of peptic ulcer, but many of these do not fulfill all the requirements and have side effects. These factors have attracted researchers to investigate the natural products which have more efficacy, less side effects and less expensive for the treatment of peptic ulcer disease. In the present study the anti ulcer activity of (1 Aloe vera juice, (2 papaya fruit juice (3 Aloe vera and papaya fruit combined juice were investigated in the ethanol induced ulcerated rats. The administration of plant juices decreased the offensive factors like ulcer index and acid secretion and also reduced the amount of protein and carbohydrates in the stomach fluid. Further, plant juices increased the defensive factors like activity of oxidative enzymes such as superoxide dismutase and reduced glutathione. Activities of alkaline phosphatase and lipid peroxide were higher in the diseased condition and same were reduced after the treatment with plant juices. Content of haemoglobin and RBC and WBC counts were brought back to normalcy after the treatment with plant juices. The efficacy of plant juices was comparable with the reference drug- Ranitidine. The results of the present study reveal that the plant juices are having efficiency in the gastroprotective activity. It is recommended that the above said plant juices can be further studied for their anti ulcer efficacy in human subjects.

    2011-01-01

    The German Salmonella Monitoring Programme started by the QS-System in 2002 (Blaha, 2004) is mandatory due to the so-called "Salmonella Regulation for Pigs" since 2007 (Anonym, 2007). The Regulation does not clearly prescribe the specific muscle which is to be taken as source of the meat juice. Thus, at different slaughter plants meat samples are also taken from different muscles and several scientific papers describe various muscles as source of the meat juice, too. The objective of this study was to compare the serological results of meat juices from three different locations (diaphragm pillar, neck, belly muscle) to each other and to those of the blood serum from exactly the same animals. All samples were simultaneously tested for Salmonella antibodies by two serological tests (Salmo-type Pig Screen, LDL, Germany; HerdChek Swine Salmonella, IDEXX, Germany). Comparisons were carried out between the various sample kinds per animal and between the two test systems. The analysis of all results of the meat juices revealed in both test systems a clear decline of the OD% values from the diaphragm pillar to the neck to the belly muscle. The average OD% values of all samples were higher when measured by the HerdChek ELISA (IDEXX, Germany) than by the Salmotype ELISA (LDL, Germany), especially in blood serum. Since the results of the meat juice samples gained from the diaphragm pillar were in both test systems by far the closest to the results of the corresponding serum blood samples, it is recommended to amend the "Salmonella Regulation for Pigs" by prescribing meat from the diaphragm pillar as the only muscle for gaining meat juice.

    Fe-deficiency anaemia is a worldwide health problem. We studied the influence of consuming an Fe-fortified fruit juice on Fe status in menstruating women. A randomised, double-blind, placebo-controlled study of 16 weeks of duration was performed. Subjects were randomised into two groups: the P group (n 58) or the F group (n 64), and consumed, as a supplement to their usual diet, 500 ml/d of a placebo fruit juice or an Fe-fortified fruit juice, respectively. The Fe-fortified fruit juice, containing microencapsulated iron pyrophosphate, provided 18 mg Fe/d (100 % of the RDA). At baseline and monthly, dietary intake, body weight and Fe parameters were determined: total erythrocytes, haematocrit, mean corpuscular volume (MCV), red blood cell distribution width (RDW), Hb, serum Fe, serum ferritin, serum transferrin, transferrin saturation, soluble transferrin receptor (sTfR) and zinc protoporphyrin (ZnPP). The fruit juice consumption involved increased intake of carbohydrates and vitamin C, and increased BMI within normal limits. Ferritin was higher in the F group after week 4 (P fruit juice improves Fe status and may be used to prevent Fe-deficiency anaemia.

    Purple carrot juice was clarified by microfiltration. Two modes of filtration, batch concentration and total recycle were tested and the effect of microfiltration process on permeate flux and membrane fouling was studied. Intrinsic membrane resistance was negligible compared with the fouling resistances, which was less than 5 % of total resistance. Determination of membrane hydraulic permeability showed that water cleaning could permit a recovery of about 7 % of initial hydraulic flux. The analysis of color parameters of feed, permeate and concentrate juice during filtration shows that the a* and b* values decrease for the permeate corresponding respectively to changes from green to red and from blue to yellow. The total sugar and reducing sugars increase in permeate and decrease in concentrate. This work showed that it was possible to clarify the purple carrot juice by microfiltration with a real amelioration of the juice appearance.

    Enamel demineralization was studied over periods related to normal use of an orange juice, an apple juice, Pepsi Cola and Diet Pepsi Cola. Rectangular blocks of intact human enamel (3 mm x 3 mm) were cut from teeth, coated with nail varnish except for the enamel surface and exposed to the drinks for 2, 4, 5, 6 or 40 minutes. The amount of calcium released from the enamel into solution was determined with the use of an atomic absorption spectrophotometer. The results showed the following degree of enamel demineralization: Pepsi Cola = orange juice greater than apple juice greater than Diet Pepsi Cola. The results suggest that diet colas are less demineralizing than other acid drinks, and complementary plaque studies indicate that they are also less cariogenic. The study emphasized the importance of acid-type, buffer capacity, pH and the presence of other components on the degree of enamel demineralization.

    The relationship between total soluble sugar content and Brix in stalk juice of sweet sorghum was determined through one-dimensional linear regression. Meanwhile, bioethanol fermentation experiments were conducted in shaking flasks and 10 l fluidized bed bioreactor with stalk juice of Yuantian No. 1 sweet sorghum cultivar when immobilized yeast was applied. The experimental results in the shaking flasks showed that the order of influence on improving ethanol yield was (NH{sub 4}){sub 2}SO{sub 4}>MgSO{sub 4}>K{sub 2}HPO{sub 4}, and the optimum inorganic salts supplement dose was determined as follows: K{sub 2}HPO{sub 4} 0%, (NH{sub 4}){sub 2}SO{sub 4} 0.2%, MgSO{sub 4} 0.05%. When the optimum inorganic salts supplement dose was used in fermentation in 10 l fluidized bed reactor, the fermentation time and ethanol content were 5 h and 6.2% (v/v), respectively, and ethanol yield was 91.61%, which was increased by 9.73% than blank. In addition, the results showed that the fermentation time was about 6-8 times shorter in fluidized bed bioreactor with immobilized yeast than that of conventional fermentation technology. As a result, it can be concluded that the determined optimum inorganic salts supplement dose could be used as a guide for commercial ethanol production. The fluidized bed bioreactor with immobilized yeast technology has a great potential for ethanol fermentation of stalk juice of sweet sorghum. (author)

    are on more than 1 of these medications but, even with polypharmacy and optimal dosing, only 40%–60% of patients report partial relief of symptoms, and many have significant adverse effects, such as somnolence, constipation, and drug dependence. Objective Tart cherry juice has been shown to be effective in the treatment of some inflammatory conditions and has a very low incidence of adverse effects. The purpose of this study was to determine whether tart cherry juice is an effective treatment for neuropathic pain from nondiabetic peripheral polyneuropathies. Methods The study group consisted of 12 primary care patient volunteers with painful lower extremity peripheral neuropathy. Patients with diabetic peripheral neuropathy were excluded due to the potentially confounding effect of the increased glycemic load from cherry juice. All study patients had carried a diagnosis of peripheral neuropathy for 5–10 y. All patients described 9–10 out of 10 pain more than 50% of the time. All study patients had been on multiple antiepileptics, analgesics, and antidepressants for more than 2 y without significant improvement of symptoms. All study patients were allowed to remain on their prescribed doses of gabapentin, pregabalin, SNRIs, tricyclics, and SSRIs during the study. The patients agreed not to use NSAIDs, steroids, lidocaine, and narcotic pain relievers during the study. There were no restrictions on diet or activity. Presumed etiologies of the peripheral neuropathies in the study group were: 3 HIV, 2 chemotherapy-induced, 5 spinal disorders, and 2 idiopathic. All patients drank 4 oz of tart cherry juice 2 ×/d for 14 d. The juice used was a combination of Prunus cerasus, Prunus acida, Prunus avium, and Prunus fructicosa, imported from the Caucasus and sold commercially as “100% cherry juice from concentrate.” Results After 14 d of treatment, the patients were questioned regarding the level of their peripheral neuropathy pain.

    The objective of this research was to characterize the chemical properties of tomato juice fermented with bifidobacterial species. Tomato juice was prepared from fresh tomatoes and heated at 100 degrees C prior to fermentation. Bifidobacterium breve, Bifidobacterium longum, and Bifidobacterium infantis were inoculated in tomato juice and kept at 35 to 37 degrees C for up to 6 h. Fructooligosaccharide (FOS) was added to tomato juice prior to fermentation. The analyses for brix, total titratable acidity (TTA), pH, color, and lycopene content were conducted to characterize tomato juices fermented with bifidobacterial species. Heat treatment of tomato juice did not cause any significant changes in brix, pH, and TTA. Only the redness of tomato juice was significantly increased, as the heating time increased to 30 min. The tomato juices fermented with B. breve and B. longum exhibited significant decreases in pH (3.51 and 3.80, respectively) and significant increases in TTA (13.50 and 12.50, respectively) (P tomato juice. The addition of FOS further improved the fermentation of tomato juice by bifidobacterial species. The lycopene contents of tomato juice were significantly increased from 88 to 113 microg/g by heat treatment at 100 degrees C (P < 0.05), however did not exhibit any significant change after fermentation with bifidobacterial species.

    Full Text Available This paper shows that it is possible to improve antioxidant activity of apple juice by extraction of polyphenolic compounds from apple pomace, as waste, and their addition to the apple juice. Raw apple juice was prepared by pressing of apple mash. After thermal treatment of raw apple juice, depectinisation, additional clarification and filtration, the clarified juice was obtained. In raw and clarified apple juice soluble solids, acidity, reducing sugar, total sugars and brown component content were determined, as well as total dry matter, ash, acidity, reducing sugar, total sugars, total pectins, cellulose and starch content in apple mash and pomace. The total cotent of phenolics in clarified apple juice and apple pomace extract, determined spectrophotometrically using the Folin- Ciocalteu reagent, was 0.496 mg/ml and 6.505 mg/g, respectively. The antioxidant activity of clarified and polyphenol-enriched clarified juice (with addition of apple pomace extract in the concentrations 0.05 g, 0.1 g, 0.5 g and 1 g of phenolic compounds per liter of clarified apple juice was examined on stable 1,1-diphenyl-2-picrylhydrazyl (DPPH free radicals. Based on the obtained results it can be concluded that polyphenol-enriched clarified juice was more effective on DPPH radicals than the clarified apple juice.

    Full Text Available In Brazil, grape juice is a not fermented beverage, made from Vitis labrusca varieties and their hybrids. The most common form of adulteration is by the addition of apple juice. The adulterated samples can be identified by specific analysis, since apple juice has some compounds that grape has not. A more simplified and assessible way to determine this kind of adulteration is the phlorizin analysis by high performance liquid chromatography (HPLC. Phlorizin is a phenolic compound that has been used to identify adulterations in juices. Besides phlorizin, it can be seen that adulteration by quantifying the levels of sorbitol, present in apples, but absent in healthy grapes. The content of this compounds in grape juices can vary due to the variety of grape and harvest.This study aimed to analyze phlorizin and sorbitol, in 141 experimental samples of Vitis labrusca grape juices, harvest 2016, of 9 varieties and 43 commercial samples (different vintages. The experimental juices from red grapes showed higher sorbitol content than the white grapes. For sorbitol analysis, the juices of Ives differed statistically of the juices of: Isabella, Concord, Niagara Branca and White Muscat. It was detected the presence of apple juice in 5 commercial grape juices.

  15. Fruit Juice in Infants, Children, and Adolescents: Current Recommendations.

    Heyman, Melvin B; Abrams, Steven A

    2017-06-01

    Historically, fruit juice was recommended by pediatricians as a source of vitamin C and as an extra source of water for healthy infants and young children as their diets expanded to include solid foods with higher renal solute load. It was also sometimes recommended for children with constipation. Fruit juice is marketed as a healthy, natural source of vitamins and, in some instances, calcium. Because juice tastes good, children readily accept it. Although juice consumption has some benefits, it also has potential detrimental effects. High sugar content in juice contributes to increased calorie consumption and the risk of dental caries. In addition, the lack of protein and fiber in juice can predispose to inappropriate weight gain (too much or too little). Pediatricians need to be knowledgeable about juice to inform parents and patients on its appropriate uses. Copyright © 2017 by the American Academy of Pediatrics.

    Obesity is a multifactorial disease that comes from an imbalance between food intake and energy expenditure. Moreover, studies have shown a relationship between mitochondrial dysfunction and obesity. In the present study, we investigated the effect of acerola juices (unripe, ripe, and industrial) and its main pharmacologically active components (vitamin C and rutin) on the activity of enzymes of energy metabolism in the brain of mice fed a palatable cafeteria diet. Two groups of male Swiss mice were fed on a standard diet (STA) or a cafeteria diet (CAF) for 13 weeks. Afterwards, the CAF-fed animals were divided into six subgroups, each of which received a different supplement for one further month (water, unripe, ripe or industrial acerola juices, vitamin C, or rutin) by gavage. Our results demonstrated that CAF diet inhibited the activity of citrate synthase in the prefrontal cortex, hippocampus, and hypothalamus. Moreover, CAF diet decreased the complex I activity in the hypothalamus, complex II in the prefrontal cortex, complex II-III in the hypothalamus, and complex IV in the posterior cortex and striatum. The activity of succinate dehydrogenase and creatine kinase was not altered by the CAF diet. However, unripe acerola juice reversed the inhibition of the citrate synthase activity in the prefrontal cortex and hypothalamus. Ripe acerola juice reversed the inhibition of citrate synthase in the hypothalamus. The industrial acerola juice reversed the inhibition of complex I activity in the hypothalamus. The other changes were not reversed by any of the tested substances. In conclusion, we suggest that alterations in energy metabolism caused by obesity can be partially reversed by ripe, unripe, and industrial acerola juice.

    Phytochemicals from fruit and vegetables reduce systemic inflammation. This study examined the effects of an encapsulated fruit and vegetable (F&V) juice concentrate on systemic inflammation and other risk factors for chronic disease in overweight and obese adults. A double-blinded, parallel, randomized placebo-controlled trial was conducted in 56 adults aged ≥40 years with a body mass index (BMI) ≥28 kg/m². Before and after eight weeks daily treatment with six capsules of F&V juice concentrate or placebo, peripheral blood gene expression (microarray, quantitative polymerase chain reaction (qPCR)), plasma tumour necrosis factor (TNF)α (enzyme-linked immunosorbent assay (ELISA)), body composition (Dual-energy X-ray absorptiometry (DEXA)) and lipid profiles were assessed. Following consumption of juice concentrate, total cholesterol, low-density lipoprotein (LDL) cholesterol and plasma TNFα decreased and total lean mass increased, while there was no change in the placebo group. In subjects with high systemic inflammation at baseline (serum C-reactive protein (CRP) ≥3.0 mg/mL) who were supplemented with the F&V juice concentrate (n = 16), these effects were greater, with decreased total cholesterol, LDL cholesterol and plasma TNFα and increased total lean mass; plasma CRP was unchanged by the F&V juice concentrate following both analyses. The expression of several genes involved in lipogenesis, the nuclear factor-κB (NF-κB) and 5' adenosine monophosphate-activated protein kinase (AMPK) signalling pathways was altered, including phosphomevalonate kinase (PMVK), zinc finger AN1-type containing 5 (ZFAND5) and calcium binding protein 39 (CAB39), respectively. Therefore, F&V juice concentrate improves the metabolic profile, by reducing systemic inflammation and blood lipid profiles and, thus, may be useful in reducing the risk of obesity-induced chronic disease.

    Doctor shopping is a primary method of prescription medication diversion. After opioids, benzodiazepines and stimulants are the next most common prescription medications used nonmedically. Studies have shown that patients who engage in doctor shopping find it fun, exciting, and easy to do. There is a lack of research on the prescriber's perspective on the phenomenon of doctor shopping. This study investigates the experiences of prescribers in psychiatry with patients who engage in doctor shopping. Fifteen prescribers including psychiatrists and psychiatric nurse practitioners working in outpatient psychiatry were interviewed to elicit detailed information about their experiences with patients who engage in doctor shopping. Themes found throughout the interview were that psychiatric prescribers' experience with patients who engage in doctor shopping includes (a) detecting red flags, (b) negative emotional responding, (c) addressing the patient and the problem, and (d) inconsistently implementing precautions. When red flags were detected when prescribing controlled drugs, prescribers in psychiatry experienced both their own negative emotional responses such as disappointment and resentment as well as the negative emotions of the patients such as anger and other extreme emotional responses. Psychiatric prescribers responded to patient's doctor shopping in a variety of ways such as changing their practice, discharging the patients or taking steps to not accept certain patients identified as being at risk for doctor shopping, as well as by talking to the patient and trying to offer them help. Despite experiencing doctor shopping, the prescribers inconsistently implemented precautionary measures such as checking prescription drug monitoring programs.

    Full Text Available An objective of this work was to assess the biological activity of beetroot juice (Chrobry variety, Beta vulgaris L. ssp. vulgaris, which was lactofermented by probiotic bacteria Lactobacillus brevis 0944 and Lactobacillus paracasei 0920. The oxidative status of blood serum, kidneys, and liver of rats consuming the fermented beetroot juice were determined. The experimental rats were divided into four groups on diet type: Basal diet, basal diet supplemented with fermented beetroot juice, basal diet and N-nitroso-N-methylurea treatment, and basal diet supplemented with fermented beetroot juice and N-nitroso-N-methylurea treatment. Mutagen N-nitroso-N-methylurea, which was added to diet in order to induce aberrant oxidative and biochemical processes and disadvantageous changes in the count and metabolic activity of the gut epithelium microbiota. The nutritional in vivo study showed that supplementing the diet of the rats with the lactofermented beetroot juice reduced the level of ammonia by 17% in the group treated with N-nitroso-N-methylurea. Furthermore, the positive modulation of the gut microflora and its metabolic activity was observed in groups of rats fed with the diet supplemented with the fermented beetroot juice. A concomitant decrease in the b-glucuronidase activity was a consequence of the gut epithelium microbiota modulation. The antioxidant capacity of blood serum aqueous fraction was increased by about 69% in the group of rats treated N-nitroso-N-methylurea mixed with the fermented beetroot juice and N-nitroso-N-methylurea versus to the N-nitroso-N-methylurea treatment, whereas the antioxidant parameters of the blood serum lipid fraction, kidneys, and liver remained unchanged.

    The influence of temperature and the presence of N(α)-lauroyl ethylester (ethyl lauroyl arginate, LAE) on the inactivation caused by continuous pulsed electric field treatments (PEF) in Escherichia coli O157:H7 suspended in apple juice have been investigated to define treatment conditions applicable at industrial scale that promote an equivalent safety level when compared with thermal processing. In the range of experimental conditions investigated (outlet temperature: 20-40 °C, electric field strength: 20-30 kV, treatment time: 5-125 μs) at outlet temperatures equal or lower than 55±1 °C, the inactivation of E. coli O157:H7 treated in apple juice ranged from 0.4 to 3.6 Log₁₀ cycles reduction and treated in apple juice supplemented with LAE (50 ppm) ranged from 0.9 to 6.7 Log₁₀ cycles reduction. An empirical mathematical model was developed to estimate the treatment time and total specific energy input to obtain 5 Log₁₀ cycles reduction in the population of E. coli O157:H7 suspended in apple juice supplemented with 50 ppm of LAE at different electric field strengths and inlet temperatures. Treatment conditions established for E. coli O157:H7 were validated with other PEF resistant Gram-positive (Listeria monocytogenes, and Staphylococcus aureus) and Gram-negative (Salmonella enterica serovar Typhimurium) strains. When the treatment was applied to the apple juice, a treatment of 25 kV/cm for 63 μs corresponding with an outlet temperature of 65 °C and input energy of 125 kJ/kg was required to achieve more than 5 Log₁₀ cycles in the four strains investigated. The addition of LAE reduced the treatment time required to obtain an equivalent inactivation (>5 Log₁₀ cycles) in the four microorganisms to 38.4 μs, the outlet temperature to 55 °C, and the input energy to 83.2 kJ/kg.

    Effects of commercial scale pulsed electric field (PEF) processing on the quality of tomato juice were studied and compared with those of thermal processing. Tomato juice was prepared by hot break at 88 degrees C for 2 min or by cold break at 68 degrees C for 2 min and then thermally processed at 92 degrees C for 90 s or PEF processed at 40 kV/cm for 57 micros. Thermally processed, PEF processed, and unprocessed control juices were packed into 50 mL sterilized polypropylene tubes in a sanitary glovebox and stored at 4 degrees C for 112 days. Both thermally and PEF processed juices showed microbial shelf life at 4 degrees C for 112 days. The lipoxygenase activities of thermally and PEF processed juices were 0 and 47%, respectively. PEF processed juice retained more ascorbic acid than thermally processed juice at 4 degrees C for 42 days (p Brix, pH, or viscosity between thermally and PEF processed juices during the storage (p > 0.05). Sensory evaluations indicated that flavor and overall acceptability of PEF processed juice were preferred to those of thermally processed juice (p < 0.05).

    Despite a common perception that fruit juice is healthy, fruit juice contains high amounts of naturally occurring sugar without the fibre content of the whole fruit. Frequent fruit juice consumption may therefore contribute to excessive sugar consumption typical of the Western society. Although excess sugar intake is associated with high blood pressure (BP), the association between habitual fruit juice consumption and BP is unclear. The present study investigated the association of fruit juice consumption with brachial and central (aortic) BP in 160 community dwelling adults. Habitual fruit juice consumption was measured using a 12 month dietary recall questionnaire. On the same day, brachial BP was measured and central (aortic) BP was estimated through radial artery applanation. Frequency of fruit juice consumption was classified as rare, occasional or daily. Those who consumed fruit juice daily, versus rarely or occasionally, had significantly higher central systolic BP (F (2, 134) = 6.09, p fruit juice daily rather than rarely or occasionally. In conclusion, more frequent fruit juice consumption was associated with higher central BPs.

    The potential of potato juice in relieving gastrointestinal disorders has already been proven. Work continues on implementation of this active component into products that are widely consumed. In this article, results of an attempt to fortify pasta with potato juice are presented and discussed. Fortification is performed using fresh and dried juice. The influence of the addition on culinary properties of the final product, such as cooking weight and cooking loss, as well as microstructure, color, texture, and consumer acceptance were evaluated. It was found that potato juice can be used for fortification of pasta both in its fresh and dried forms, however the effects on different responses depend on the potato juice form used. The addition of potato juice influenced the color of the product reducing its lightness and shifting color balances from green to red, yellow color saturation was decreased as well. Changes in color were more significant in the case of fresh juice addition. The firmness and microstructure of pasta was also influenced. The surface microstructure of pasta containing fresh potato juice was different from that of the other 2 products being a likely explanation of the lower cooking loss observed in its case. In contrast, the consistency of dough was strengthened by addition of dried potato juice. Principal components analysis indicated that the color change had the most pronounced effect on consumer acceptance. Other physicochemical changes were slightly less significant. Nevertheless, sensory evaluation proved that functional pasta produced with fresh potato juice finds consumer acceptance comparable with that of classic pasta.

    Full Text Available Fruit juices are popular drinks as they contain antioxidants, vitamins, and minerals that are essential for human being and play important role in the prevention of heart diseases, cancer, and diabetes. They contain essential nutrients which support the growth of acid tolerant bacteria, yeasts, and moulds. In the present study, we have conducted a microbiological examination of freshly prepared juices (sweet lime, orange, and carrot by serial dilution agar plate technique. A total of 30 juice samples were examined for their microbiological quality. Twenty-five microbial species including 9 bacterial isolates, 5 yeast isolates, and 11 mould isolates were isolated from juices. Yeasts and moulds were the main cause of spoilage of juices. Aspergillus flavus and Rhodotorula mucilaginosa were observed in the maximum number of juice samples. Among bacteria Bacillus cereus and Serratia were dominant. Escherichia coli and Staphylococcus aureus were detected in few samples. Candida sp., Curvularia, Colletotrichum, and Acetobacter were observed only in citrus juice samples. Alternaria, Aspergillus terreus, A. niger, Cladosporium, and Fusarium were also observed in tested juice samples. Some of the microorganisms detected in these juice samples can cause disease in human beings, so there is need for some guidelines that can improve the quality of fruit juices.

    OBJECTIVE: To estimate the prevalence of questionable and rational high-risk prescribing among elderly people of the three drug groups most commonly implicated in drug-related illness: cardiovascular drugs, psychotropic drugs and nonsteroidal anti-inflammatory drugs (NSAIDs). DESIGN: Retrospective prevalence study; all prescription and billing records for the period Jan. 1 to Dec. 31, 1990, for the study sample were retrieved from the relevant provincial databases of the Régie de l'assurance-maladie du Québec. SETTING: Quebec. PARTICIPANTS: Regionally stratified random sample of 63,268 elderly medicare registrants who made at least one visit to physician in 1990 and were not living in a health care institution for the entire year. MAIN OUTCOME MEASURE: Prescription information was examined for three types of high-risk prescribing: rational and questionable drug combinations, excessive treatment duration and drugs relatively contraindicated for use in elderly people. RESULTS: Overall, 52.6% of the patients experienced one or more events of high-risk prescribing, and 45.6% experienced at least one that was questionable. High-risk prescribing was most prevalent for psychotropic drugs, and questionable prescribing was more frequent than rational prescribing in this drug group. An estimated 30.8% of the total elderly population in Quebec received benzodiazepines for more than 30 consecutive days, 12.9% received a long-acting benzodiazepine, and 13.0% received a questionable high-risk psychotropic drug combination. The prevalence of high-risk prescribing was higher among the women than among the men and increased with age until 75 to 84 years. There were significant unexplained differences between regions in the regional prevalence of high-risk prescribing, particularly of psychotropic drugs. CONCLUSION: The prevalence of questionable high-risk prescribing, especially of psychotropic drugs, is substantial among elderly people. This may be a potentially important and

    Full Text Available Poultry feed derived from grains has an anti-nutrient phytic acid. Naturally, phytate forms a complex bond with some minerals (P, Zn, Fe, Mg, and Ca, protein, and amino acids. The mineral-phytate complex cannot be absorbed by the small intestine of non-ruminant livestock and will adversely affect the availability of minerals in the ration. One way to improve the efficiency of mineral and protein utilization from phytate is using phytase. Sugarcane juice containing nutrients and phytase is very potential as liquid supplement for broiler chickens as it can hydrolyze phytic acid. The purpose of this study was to determine the retention of nitrogen, metabolism energy, and retention of minerals (P, Ca and Zn of sugarcane juice in broilers. The study was conducted for 7 days using metabolism cages for 28 broilers of 5 weeks old with 6 treatments of 4 replications, 4 for endogenous. The results showed that the administration of 2.5%/kg sugarcane juice in the ration as well as in 2.5%/liter sugarcane juice in drinking water could provide the same result as giving commercial phytase 250-500 FTU/kg on the retention of nitrogen, metabolizeable energy, and retention of minerals P, Ca and Zn.

One solution to the challenges of care delivery has been the introduction of nurse practitioners (NPs and the authorization of NPs to prescribe medicines. Aim: The aim of this paper was to review the current international literature related to NP prescribing and compare the findings to the Australian context. The review focuses on literature from the United States, Canada, Europe, Australia, and New Zealand. Methods: Databases were searched from January 2000 to January 2015. The following keywords: “nurse practitioner”, “advanced nurse”, “advanced practice nurse”, “prescri*”, “Australia”, “United States America”, “UK”, “New Zealand”, “Canada”, “Europe”, “drug prescri*”, “prescri* authority”, and “prescri* legislation” were used. Findings: NPs tend to prescribe in differing contexts of practice to provide care in underserved populations and require good systems literacy to practice across complex systems. The key themes identified internationally related to NP prescribing relate to barriers to prescribing, confidence in prescribing, and the unique role of NPs in prescribing medicines, eg, the high prevalence of prescribing pain medicines in several countries, including Australia. Conclusion: Across all countries reviewed, there appears a need for further research into the organizational and

    A potentiometric method using a fluoride combination ion-selective electrode was validated and used to analyse 183 samples, including soft drinks, juices, nectars, juice drinks, concentrates, teas and infusions marketed in Portugal. The fluoride levels were higher in extract-based soft drinks, juice drinks and juice, with fluoride values of 0.86 ± 0.35, 0.40 ± 0.24 and 0.37 ± 0.11 mg l⁻¹, respectively. The lowest fluoride concentration was found in infusion samples (0.12 ± 0.01 mg l⁻¹), followed by teas and carbonated soft drinks with fluoride concentrations of 0.16 ± 0.12 and 0.18 ± 0.07 mg l⁻¹, respectively. Nectars, concentrates and juice-based drinks had similar fluoride concentrations of 0.33 ± 0.16, 0.29 ± 0.12 and 0.25 ± 0.14 mg l⁻¹, respectively. The fluoride concentrations in all these samples would only contribute intakes below the acceptable daily intake (ADI = 0.05 mg kg⁻¹ body weight day⁻¹), indicating that, individually, these beverages cannot induce fluoride toxicity in the population group of children.

    Full Text Available The aim of the study was to assess the effect of three weeks of storage on the chemical and rheological properties of apple juices obtained from Idared and Jonatan apples variety. Total antioxidant activity, levels of bio-active compound groups and the viscosity were measured to characterize the investigated juices. The method applied for the determination of ascorbic acid concentration was with 2, 6-diclorophenolindophenol. Total phenols (TP in apple juices were determined using the Folin-Ciocalteau method and antioxidant activity by the use of DPPH free radical method. The viscosity of apple juices was investigated by a rotational viscometer, Brookfield viscometer (Brookfield Engineering Inc., Model RV-DV I Prime with RV spindles. During three weeks of storage, different rates of all measured properties have been observed decreasing for both studied apples varieties juices. The juices from Jonatan apples have higher antioxidant activities that are correlated with the higher content in polyphenols and lower values of viscosity.

    Even though several types of phosphorus fertilizers are used in crop production, the influence of phosphorus on produce quality is not well understood. Several quality attributes of tomato juice were analyzed in relation to phosphorus supplementation during a three-year field study (2000-2002). In addition to the recommended phosphorus fertilization, phosphorus supplementations, either through soil (low and high) or through foliar spray (hydrophos, seniphos), were tested. In general, soil and foliar phosphorus supplementation did not provide a statistically significant increase in yield. Tomato juice was evaluated for various quality characteristics including pH, titratable acidity, precipitate weight ratio, total solids, serum viscosity, Brookfield viscosity, color, lycopene levels, vitamin C, and flavor volatiles. Changes observed in several quality parameters were marginal, statistically insignificant and influenced by the season. Therefore, it appears that phosphorus supplementation may not significantly affect the processing quality parameters in tomato fruits.

    In Brazil, grape juice is a not fermented beverage, made from Vitis labrusca varieties and their hybrids. The most common form of adulteration is by the addition of apple juice. The adulterated samples can be identified by specific analysis, since apple juice has some compounds that grape has not. A more simplified and assessible way to determine this kind of adulteration is the phlorizin analysis by high performance liquid chromatography (HPLC). Phlorizin is a phenolic compound that has been...

    Implementation of electronic prescribing system can overcome many problems of the paper prescribing system, and provide numerous opportunities of more effective and advantageous prescribing. Successful implementation of such a system requires complete and deep understanding of work content, human force, and workflow of paper prescribing. The current study was designed in order to model the current business process of outpatient prescribing in Iran and clarify different actions during this process. In order to describe the prescribing process and the system features in Iran, the methodology of business process modeling and analysis was used in the present study. The results of the process documentation were analyzed using a conceptual model of workflow elements and the technique of modeling "As-Is" business processes. Analysis of the current (as-is) prescribing process demonstrated that Iran stood at the first levels of sophistication in graduated levels of electronic prescribing, namely electronic prescription reference, and that there were problematic areas including bottlenecks, redundant and duplicated work, concentration of decision nodes, and communicative weaknesses among stakeholders of the process. Using information technology in some activities of medication prescription in Iran has not eliminated the dependence of the stakeholders on paper-based documents and prescriptions. Therefore, it is necessary to implement proper system programming in order to support change management and solve the problems in the existing prescribing process. To this end, a suitable basis should be provided for reorganization and improvement of the prescribing process for the future electronic systems.

    Bioethanol production from renewable sources to be used in transportation is now an increasing demand worldwide due to continuous depletion of fossil fuels, economic and political crises, and growing concern on environmental safety. Mainly, three types of raw materials, that is, sugar juice, starchy crops, and lignocellulosic materials, are being used for this purpose. This paper will investigate ethanol production from free sugar containing juices obtained from some energy crops such as sugarcane, sugar beet, and sweet sorghum that are the most attractive choice because of their cost-effectiveness and feasibility to use. Three types of fermentation process (batch, fed-batch, and continuous) are employed in ethanol production from these sugar juices. The most common microorganism used in fermentation from its history is the yeast, especially, Saccharomyces cerevisiae, though the bacterial species Zymomonas mobilis is also potentially used nowadays for this purpose. A number of factors related to the fermentation greatly influences the process and their optimization is the key point for efficient ethanol production from these feedstocks.

    Full Text Available Sugarcane juice is traditionally sold in India by roadside vendors, often in unhygienic conditions. That’s why a few entrepreneurs have taken the initiative venturing into the marketing of branded sugarcane juice through a chain of franchised outlets. Initial indications are that this model is headed for success. Pune, Kolhapur, more known for its leather chappals, has also been blessed with an abundance of milk, water and sugar, which has made the region the nation's kitchen for many years. The Warana milk producers' cooperative located here has lived up to this reputation. It has been a contract manufacturer for products such as Cadbury's Bournvita, butter for Britannia Industries and Soya milk for Ruchi Soya. Now, the cooperative is preparing to assert its own identity through the launch of Warana Joy, its national brand. Among its new products is sugarcane juice in aseptic packs (Tetra Pak. This article outlines the development of this business; the opportunities and threats faced and also offer suggestions for the growth in this market.

    Vardin, Hasan; Fenercioğlu, Hasan

    2003-10-01

    The effects of clarification agents and methods on pomegranate juice quality were studied. Fruits were pressed as whole, and extracted juice was clarified with gelatin, polyvinylypolypyrrolidone (PVPP) and natural sedimentation. In order to determine the effects of these clarifying techniques on product quality, pH, total phenolic substances (TPS), anthocyanin, turbidity, and total colour density tests were applied to each sample. In clarification, the main purpose was to reduce the amount of phenolic substances. Phenolic substances were controlled in each clarification method. The most effective method was the application of 1 g/L gelatine for clarification. Sensory evaluation also applied for clarified juices and gelatin application was selected by panelists to be superior.

    Clinicians are becoming more reliant on their interpretation of clinical trial information to guide prescribing rather than their clinical skills. Thus to improve prescribing, it is increasingly important for clinicians to have an appreciation of epistemology (the science of knowledge and its interpretation) and the broader social context of knowledge. The insights of epistemologists can be useful in understanding the different ways in which clinical trials data are interpreted.

    1999-06-01

    This study aims to analyse the prescribing pattern of doctors working in a government outpatient polyclinic in Singapore. Retrospective study of 1 week of prescription scripts in 1996. Number, types and duration of drugs prescribed; combination of drugs; age distribution; bad handwriting. Two thousand six hundred and seventy-nine scripts were analysed. The age of patients ranged from 1 to 93 years with a mean of 43.8 years. There were 44.0% males and 56.0% females. The overall mean of 'total number of drugs prescribed' was 2.8 items. The means of 'number of drug items prescribed for more than 1 week' by age-group were: 60 years = 2.4. One way analysis of variance showed significant difference between the means of each age-group. Post hoc analysis revealed that the oldest age group accounted for most of this significant result. The top 10 drugs prescribed in descending order were: antihistamines, paracetamol, throat medications (eg. lozenges, gargles, etc), nifedipine, beta-blockers, antacids, mist benadryl expectorant, Procodin cough syrup (containing codeine and promethazine), amoxycillin and vitamin B. Nifedipine and beta-blockers were the most commonly prescribed anti-hypertensives. Non-steroidal anti-inflammatory drugs were usually prescribed with antacids. One hundred and twenty (4.5%) scripts were illegible. This study provides a baseline data for monitoring future prescribing trends. There may be a need to re-evaluate the appropriateness of nifedipine as the first line anti-hypertensive drug and the usefulness of NSAID-antacid and amoxycillin-cloxacillin combinations. The prevalence of illegible handwriting was high.

    We surveyed the psychotropic drug treatment of our hospital's 220 patients, and compared our findings with those of the only previous hospital survey in this country which showed much allegedly inappropriate prescribing. Using simple classifications of the patients' diagnoses and of the drugs prescribed, 30 per cent of our prescriptions appeared inappropriate in the absence of knowledge of the patients' symptoms. With such knowledge we show that only 2 of our 460 prescriptions were inappropriate.

    Full Text Available Khaled A Elsaid,1,2 Steven Garguilo,1 Christine M Collins2 1Department of Pharmaceutical Sciences, School of Pharmacy, MCPHS University, Boston, MA, 2Pharmacy Services, Rhode Island Hospital, Providence, RI, USA Abstract: Chemotherapy drugs are characterized by low therapeutic indices and significant toxicities at clinically prescribed doses, raising serious issues of drug safety. The safety of the chemotherapy medication use process is further challenged by regimen complexity and need to tailor treatment to patient status. Errors that occur during chemotherapy prescribing are associated with serious and life-threatening outcomes. Computerized provider order entry (CPOE systems were shown to reduce overall medication errors in ambulatory and inpatient settings. The adoption of chemotherapy CPOE is lagging due to financial cost and cultural and technological challenges. Institutions that adopted infusional or oral chemotherapy electronic prescribing modified existing CPOE systems to allow chemotherapy prescribing, implemented chemotherapy-specific CPOE systems, or developed home-grown chemotherapy electronic prescribing programs. Implementation of chemotherapy electronic prescribing was associated with a significant reduction in the risk of prescribing errors, most significantly dose calculation and adjustment errors. In certain cases, implementation of chemotherapy CPOE was shown to improve the chemotherapy use process. The implementation of chemotherapy CPOE may increase the risk of new types of errors, especially if processes are not redesigned and adapted to CPOE. Organizations aiming to implement chemotherapy CPOE should pursue a multidisciplinary approach engaging all stakeholders to guide system selection and implementation. Following implementation, organizations should develop and use a risk assessment process to identify and evaluate unanticipated consequences and CPOE-generated errors. The results of these analyses should serve to

    This article suggests that nurse prescribers require an awareness of key concepts in ethics, such as deontology and utilitarianism to reflect on current debates and contribute to them. The principles of biomedical ethics have also been influential in the development of professional codes of conduct. Attention is drawn to the importance of the Association of the British Pharmaceutical Industry's code of practice for the pharmaceutical industry in regulating marketing aimed at prescribers.

    Watermelon is a natural product that contains high level of antioxidants and may prevent oxidative damage in tissues due to free radical generation following an exposure to ionizing radiation. The present study aimed to investigate the radioprotective effects of watermelon (Citrullus lanatus (Thunb.) Matsum. and Nakai) juice against oxidative damage induced by low dose X-ray exposure in mice. Twelve adult male ICR mice were randomly divided into two groups consisting of radiation (Rx) and supplementation (Tx) groups. Rx received filtered tap water, while Tx was supplemented with 50% (v/v) watermelon juice for 28 days ad libitum prior to total body irradiation by 100 μGy X-ray on day 29. Brain, lung, and liver tissues were assessed for the levels of malondialdehyde (MDA), apurinic/apyrimidinic (AP) sites, glutathione (GSH), and superoxide dismutase (SOD) inhibition activities. Results showed significant reduction of MDA levels and AP sites formation of Tx compared to Rx (P Citrullus lanatus (Thunb.) Matsum. and Nakai) juice could modulate oxidative damage induced by low dose X-ray exposure.

  1. Detection of some intestinal protozoa in commercial fresh juices.

    2010-04-01

    Fresh fruit juices are popular, but not always safe. For assessing the likelihood of infection with newly emerging intestinal protozoa, commercial fresh orange, lemon, sugar cane, strawberry, and mango juices were screened by wet mounts, Weber's modified trichrome and modified Ziehl-Neelsen stains. Protozoa viability was done by fluorescein-diacetate/propidium-iodide staining, and infectivity was performed in Swiss albino mice. Results showed that 35.43% were contaminated with one or more of Cryptosporidia, Microsporidia, and Cyclospora, as well as Giardia spp. Strawberry was the most contaminated juice (54.28%), while orange was the slightest (22.86%). Cryptosporidia was the highest contaminant (61.29%), and Cyclospora was the least (14.52%). Microsporidia spp. was the most robust contaminant which retained its viability and infectivity in juices in which it was detected. Moderately acidic strawberry and mango juices and alkaline sugar cane juice pose a possible threat, due to harboring the highest viable and infectious protozoa. Regarding highly acidic juices, viability and infectivity decreased in lemon, yet was not still risk free. Orange juice was comparatively safe, as viability dramatically declined, while infectivity was completely abolished. Hence consumers, especially high risk group, are placed at hazard of contracting intestinal protozoa infections, especially through moderately acidic and alkaline juices.

    This study aimed to investigate the effects of tomato juice consumption on seminal plasma lycopene levels and sperm parameters in infertile men. Subjects were male infertility patients with poor sperm concentration (juice group, an antioxidant group, and a control group. The subjects in the tomato juice group and the antioxidant group daily consumed one can of tomato juice (containing 30 mg of lycopene) or one antioxidant capsule (containing vitamin C 600 mg, vitamin E 200 mg, and glutathione 300 mg), respectively, for 12 weeks (feeding period). Seminal plasma lycopene levels and sperm parameters were measured every 6 weeks during the feeding period. Forty-four patients completed the study (control group: 12, antioxidant group: 15, tomato juice group: 17). In the tomato juice group, plasma lycopene level was significantly increased at the 12th week of the feeding period. Moreover, a decrease in seminal plasma white blood cells and an increase in sperm motility in the tomato juice group were statistically significant at the 12th and 6th weeks, respectively, compared to the control group. In the antioxidant capsule group, no significant improvement was observed in semen parameters. In conclusion, regular consumption of tomato juice seems to improve sperm motility in infertile patients. This is the first report to show that commercially available food, such as tomato juice, might be beneficial for male infertility.

    The photopyroelectric method was used to study the depression of freezing point in juices prepared from selected apple and orange juice concentrates. By using the models for real solutions, the effective molecular weight of the dissolved solids was obtained. The acids concentration in the fruit juice is reflected both in the equivalent molecular weight (by lowering it) and in the interaction coefficients b and C. Using the data for the molecular weight and the characteristic coefficients, prediction curves for the samples investigated can be used in practice. Freezing point depression can also be used as an indicator of the degree of spoilage of fruit juices.

    Obesity has been studied as a metabolic and an inflammatory disease and is characterized by increases in the production of pro-inflammatory adipokines in the adipose tissue.To elucidate the effects of natural dietary components on the inflammatory and metabolic consequences of obesity, we examined the effects of unripe, ripe and industrial acerola juice (Malpighia emarginata DC.) on the relevant inflammatory and lipolysis proteins in the adipose tissue of mice with cafeteria diet-induced obesity. Two groups of male Swiss mice were fed on a standard diet (STA) or a cafeteria diet (CAF) for 13 weeks. Afterwards, the CAF-fed animals were divided into five subgroups, each of which received a different supplement for one further month (water, unripe acerola juice, ripe acerola juice, industrial acerola juice, or vitamin C) by gavage. Enzyme-linked immunosorbent assays, Western blotting, a colorimetric method and histology were utilized to assess the observed data. The CAF water (control obese) group showed a significant increase in their adiposity indices and triacylglycerol levels, in addition to a reduced IL-10/TNF-α ratio in the adipose tissue, compared with the control lean group. In contrast, acerola juice and Vitamin C intake ameliorated the weight gain, reducing the TAG levels and increasing the IL-10/TNF-α ratio in adipose tissue. In addition, acerola juice intake led to reductions both in the level of phosphorylated JNK and to increases in the phosphorylation of IκBα and HSLser660 in adipose tissue. Taken together, these results suggest that acerola juice reduces low-grade inflammation and ameliorates obesity-associated defects in the lipolytic processes.

    This study aimed at investigating the effect of nitrate removal from pineapple juice by electrodialysis (ED) on selected properties of the ED-treated juice. Single-strength pineapple juice with reduced pulp content was treated by ED to reduce the nitrate concentration to 15, 10, or 5 ppm. After ED, the removed pulp was added to the ED-treated juice and its properties, including electrical conductivity, acidity, pH, total soluble solids (TSS), color, amino acids, and selected aroma compounds, were determined and compared with those of the untreated juice. ED could reduce the nitrate content of 1 L of pineapple juice from an initial value of 50 ppm to less than 5 ppm within 30 min. A significant decrease in the electrical conductivity, acidity, pH, TSS, and yellowness, but a significant increase in the lightness, of the juice was observed upon ED. Concentrations of almost all amino acids of the ED-treated juice significantly decreased. The concentrations of 8 major compound contributors to the pineapple aroma also significantly decreased. Adding the pulp back to the ED-treated juice increased the amino acids concentrations; however, it led to a significant decrease in the concentrations of the aroma compounds.

    Raspberries contain flavonoid antioxidants whose relative concentrations may vary between the juice, pulp, and seed fractions. Oxygen radical absorbance capacity (ORAC), total anthocyanin content, and berry color were determined for six cultivars of primocane raspberries grown in a dry climate (Utah, USA). Significant ORAC differences were found between juice (18.4 ± 0.39 μmol TE/g), pulp (24.45 ± 0.43), and seeds (273.27 ± 11.15) with all Utah cultivars combined. A significantly higher concentration of anthocyanins was present in Utah raspberry juice (20.86 ± 0.35 mg cyanidin-3-glucoside eq./100 g), compared to pulp (13.96 ± 0.35). Anthocyanin content of juice and pulp were significantly positively correlated with dark color (L*). This is the first report of fractional differences in dry climate raspberries, and has implications for the juice and supplement industries.

    In this study, sweet sorghum juice (SSJ) was used as the substrate in a simplified ABE fermentation-gas stripping integration process without nutrients supplementation. The sweet sorghum bagasse (SSB) after squeezing the fermentable juice was used as the immobilized carrier. The results indicated that the productivity of ABE fermentation process was improved by gas stripping integration. A total 24g/L of ABE solvents was obtained from 59.6g/L of initial sugar after 80h of fermentation with gas stripping. Then, long-term of fed-batch fermentation with continuous gas stripping was further performed. 112.9g/L of butanol, 44.1g/L of acetone, 9.5g/L of ethanol (total 166.5g/L of ABE) was produced in overall 312h of fermentation. At the same time, concentrated ABE product was obtained in the condensate of gas stripping.

    Enterocin AS-48 is a candidate bacteriocin for food biopreservation. Before addressing application of AS-48 to vegetable-based foods, the interaction between AS-48 and vegetable food components and the stability of AS-48 were studied. Enterocin AS-48 had variable interactions with fruit and vegetable juices, with complete, partial, or negligible loss of activity. For some juices, loss of activity was ameliorated by increasing the bacteriocin concentration, diluting the juice, or applying a heat pretreatment. In juices obtained from cabbage, cauliflower, lettuce, green beans, celery, and avocado, AS-48 was very stable for the first 24 to 48 h of storage under refrigeration, and decay of activity was markedly influenced by storage temperature. In fresh-made fruit juices (orange, apple, grapefruit, pear, pineapple, and kiwi) and juice mixtures, AS-48 was very stable for at least 15 days at 4 degrees C, and bacteriocin activity was still detectable after 30 days of storage. Gradual and variable loss of activity occurred in juices stored at 15 and 28 degrees C; inactivation was faster at higher temperatures. In commercial fruit juices (orange, apple, peach, and pineapple) stored at 4 degrees C, the bacteriocin was completely stable for up to 120 days, and over 60% of initial activity was still present in juices stored at 15 degrees C for the same period. Commercial fruit juices stored at 28 degrees C for 120 days retained between 31.5% (apple) and 67.71% (peach) of their initial bacteriocin activity. Solutions of AS-48 in sterile distilled water were stable (120 days at 4 to 28 degrees C). Limited loss of activity was observed after mixing AS-48 with some food-grade dyes and thickening agents. Enterocin AS-48 added to lettuce juice incubated at 15 degrees C reduced viable counts of Listeria monocytogenes CECT 4032 and Bacillus cereus LWL1 to below detection limits and markedly reduced viable counts of Staphylococcus aureus CECT 976.

    Full Text Available Street vended juices are most commonly available, accessible and economical nutritional food sources of poor slums in developing economies like Pakistan. Study was undertaken to elucidate impact of industrialization, agro chemicals induction in agronomic practices and food processing hygiene measurements on food chain heavy metals intoxication. If overlooked, certain quality risks associated either with fresh produce or processed commodity might initiate food intoxication.In order to understand gravity of the issue, street vended freshly drawn juices extracted from the food crops (orange, sugarcane, carrot and mango cultivated in Southern Punjab peri-urban areas and country sides were evaluated for microelements and heavy metals load in summer and winter 2012. The safety study of juices depicted higher concentration of lead (Pb and cadmium (Cd breaching international safety limits implemented in the country. However some microelements (Fe, Zn, Mn were found below the prescribed maximum tolerant limits. The study concluded prevalence of higher concentration of some toxic heavy metals as a serious breach of threshold levels potentially compromising consumer’s safety.

    Full Text Available Abstract Background The introduction of non-medical prescribing for professions such as pharmacy and nursing in recent years offers additional responsibilities and opportunities but attendant training issues. In the UK and in contrast to some international models, becoming a non-medical prescriber involves the completion of an accredited training course offered by many higher education institutions, where the skills and knowledge necessary for prescribing are learnt. Aims: to explore pharmacists' perceptions and experiences of learning to prescribe on supplementary prescribing (SP courses, particularly in relation to inter-professional learning, course content and subsequent use of prescribing in practice. Methods A postal questionnaire survey was sent to all 808 SP registered pharmacists in England in April 2007, exploring demographic, training, prescribing, safety culture and general perceptions of SP. Results After one follow-up, 411 (51% of pharmacists responded. 82% agreed SP training was useful, 58% agreed courses provided appropriate knowledge and 62% agreed that the necessary prescribing skills were gained. Clinical examination, consultation skills training and practical experience with doctors were valued highly; pharmacology training and some aspects of course delivery were criticised. Mixed views on inter-professional learning were reported – insights into other professions being valued but knowledge and skills differences considered problematic. 67% believed SP and recent independent prescribing (IP should be taught together, with more diagnostic training wanted; few pharmacists trained in IP, but many were training or intending to train. There was no association between pharmacists' attitudes towards prescribing training and when they undertook training between 2004 and 2007 but earlier cohorts were more likely to be using supplementary prescribing in practice. Conclusion Pharmacists appeared to value their SP training and

    1988-01-01

    A rearranged equation of Sargent and Gotch (1) was used to determine dialysate bicarbonate concentrations for hemodialysis patients. Parameters in this equation include an estimate of the acid generated by each patient between treatments, an estimate for the dialyzer dialysance for bicarbonate, ultrafiltration rate, blood flow rate and a targeted mid-dialysis plasma bicarbonate concentration of 25 mEq/L. Nine patients were studied over a 35 week period to verify this method of determining each patient's dialysate bicarbonate concentration. Prescribed dialysate bicarbonate concentrations for the nine patients varied from 29 to 38 mEq/L with five patients having a prescribed value of 35 mEq/L. After a baseline period of five weeks, five patients switched from a 37 mEq/L acetate dialysate to their prescribed dialysate bicarbonate concentration. Four patients who had already been on bicarbonate dialysis at a concentration of 35 mEq/L were dialyzed with their prescribed dialysate bicarbonate concentrations. Patients were then followed for a study period of 30 weeks. The prescribed dialysate bicarbonate concentration resulted in more normal acid/base chemistries for both groups of patients. The results also demonstrate that chronic hemodialysis patients require individualization of dialysate bicarbonate concentrations.

    To describe patterns of antidepressant (ADs) prescribing in community oncology practice. Data were collected using an electronic medical record on all staged breast, colon, and lung cancer patients in three community-based oncology practices. The data were analyzed retrospectively, using descriptive and bivariate analyses and multivariate logistic regression modeling. There were 850 breast, 299 colon, and 473 lung cancer patients identified in this analysis. Overall, 19.2% of breast, 11% of colon, and 13.7% of lung cancer patients had been prescribed ADs during the 2-year period. The clinic in which cancer treatment was received predicted AD prescribing. The relationship between AD administration and age proved to be nonlinear; the pattern exhibited an "inverted U" shape. Patients with comorbidities and on pain medications were more likely to be administered ADs. Colon cancer patients on pain medications were five times more likely to be administered ADs than those not on pain medications. While some predictors of AD prescribing appear to be consistent with other studies, such as being on pain medication, there is still a great amount of variability in prescribing patterns across community practices, age groups, and cancer diagnoses. This study demonstrates that prescriptions of ADs seem to be influenced by parameters other than psychopathology. Given the importance of major depression in oncology care, diagnosis of psychiatric disorders and prescription patterns of psychotropics should be part of the routine monitoring and quality management in oncology patient care.

    Full Text Available We retrospectively evaluated the results of pancreatic juice cultures of patients with acute pancreatitis and other pancreatic disorders. Methods Twenty patients who underwent pancreatic juice culture were studied. Nine had acute pancreatitis due to alcohol (n=5, idiopathic causes (n=2, drugs (n=1, or gallstones (n=1, and remaining 11 had other pancreatic disorders such as an intraductal papillary mucin-producing neoplasm (n=3 and main pancreatic duct dilatation with a stricture due to a tumorous lesion suspected of pancreatic cancer (n=7 or chronic pancreatitis (n=1 without symptoms. Nasopancreatic drainage tubes were placed for pancreatic duct drainage in acute pancreatitis and for pancreatic juice cytology in other disorders. Pancreatic juice was obtained through the drainage tube and cultured. Results Pancreatic juice cultures were positive in all patients with acute pancreatitis for Staphylococcus epidermidis, Streptococcus species, and others. Six among 11 patients (54.5% with other disorders showed positive results for Escherichia coli, Streptococcus salivarius, and others. The rate of positive pancreatic juice cultures was significantly higher in acute pancreatitis (p=0.038. Seven of the 9 patients with acute pancreatitis were classified as having severe acute pancreatitis, and all survived treatment. Conclusions Pancreatic juice culture was highly positive in acute pancreatitis. Further study is needed to confirm the relationship between orally indigenous bacteria identified in the pancreatic juice and acute pancreatitis.

    Full Text Available Brazil is the world's largest producer of oranges and uses more than 70% of the harvested fruits in the production of juices. The amount of processed orange is growing about 10% per year, confirming the trend of the Brazilian citrus for juice production. This research aimed to investigate the Brazilian orange juice production chain from 2005 to 2009. Data from the amount of frozen juice produced and exported, international price of orange juice, and intermediate transactions were assessed in order to make possible selection of all interveners involved in the chain. The study using the Social Network Analysis (SNA showed that the densest relationships in the network are from exporters to importers and from orange growers to the orange processing industry. No difference was found in the values of the network geodesic distance or the clustering coefficients from 2005 to 2009. The degree of centrality increased steadily throughout the years indicating that the processing industry attempts to minimize the risks by centralizing the actions. A decrease in export of orange juice from 2007 (2.07 10(6 t to 2008 (2.05 10(6 t was found, probably due to the world's financial crisis with recovery in 2009. Since 2004, there has been an increase of nearly 10% per year in the market preference of concentrate juice (OFCJ when compared to the "not from concentrated" juice (NFC. Nowadays the NFC market represents nearly 50% of all Brazilian export which impacted in the logistic distribution and transportation issues.

    Full Text Available Apple juice, for its sensory and nutritional qualities, is consumed by people of all ages. Apples are an excellent source of several phenolic compounds and the presence of polyphenols is recognized for their health promoting antioxidant properties. Thermal pasteurization of fruit juices is the conventional method used for their preservation. Therefore, this constitutes the most extensively available methods for the inactivation of microorganisms in fruit juices but it causes side effects on their flavour and nutritional quality. Consumers tend to prefer recently extracted juices with fresh taste and minimal flavor or vitamin losses. To meet consumers’ demand, among the novel technologies that involve non-thermal processes, power ultrasound have been investigated as an alternative to conventional heat treatments. Objective of this study was to evaluate the effectiveness of the use of ultrasound in an attempt to maintain the organoleptic characteristics typical of a natural apple juice. In particular, it was evaluated the action on the microflora residing and shelf life of the product through microbiological and sensory analyses. Juice treated with ultrasound highlighted a reduction of aerobic mesophilic counts and psychrophilic bacteria respectively about 3 and 5 log CFU/mL and an enhanced yeast growth. The general opinion expressed by the panelist was in favour of the sonicated juice. This preliminary study showed that non-thermal methods such as power ultrasound technology may give new opportunities to develop fresh-like apple juice.

  19. Evaluation of the fermentation of high gravity thick sugar beet juice worts for efficient bioethanol production

    Science.gov (United States)

    2013-01-01

    Background Sugar beet and intermediates of sugar beet processing are considered to be very attractive feedstock for ethanol production due to their content of fermentable sugars. In particular, the processing of the intermediates into ethanol is considerably facilitated because it does not require pretreatment or enzymatic treatment in contrast to production from starch raw materials. Moreover, the advantage of thick juice is high solid substance and saccharose content which eliminates problems with the storability of this feedstock. Results The objective of this study were to investigate bioethanol production from thick juice worts and the effects of their concentration, the type of mineral supplement, as well as the dose of yeast inoculum on fermentation dynamics and ethanol yield. The obtained results show that to ensure efficient ethanolic fermentation of high gravity thick juice worts, one needs to use a yeast strain with high ethanol tolerance and a large amount of inoculum. The highest ethanol yield (94.9 ± 2.8% of the theoretical yield) and sugars intake of 96.5 ± 2.9% were obtained after the fermentation of wort with an extract content of 250 g/kg supplemented with diammonium hydrogen phosphate (0.3 g/L of wort) and inoculated with 2 g of Ethanol Red dry yeast per L of wort. An increase in extract content in the fermentation medium from 250 g/L to 280 g/kg resulted in decreased efficiency of the process. Also the distillates originating from worts with an extract content of 250 g/kg were characterized by lower acetaldehyde concentration than those obtained from worts with an extract content of 280 g/kg. Conclusions Under the favorable conditions determined in our experiments, 38.9 ± 1.2 L of 100% (v/v) ethyl alcohol can be produced from 100 kg of thick juice. The obtained results show that the selection of process conditions and the yeast for the fermentation of worts with a higher sugar content can improve the economic performance of the

  1. Prescribing restrictions – a necessary strategy among some European countries to enhance future prescribing efficiency?

    Directory of Open Access Journals (Sweden)

    Brian Godman

    2012-01-01

    Full Text Available The unsustainable growth in pharmaceutical expenditure has resulted in multiple initiatives across Europe to lower prices of generics and enhance their utilisation. These include prescribing restrictions. However, there have been concerns with their impact on subsequent quality of care as well as their influence in reality. OBJECTIVES: (a Review the influence of prescribing restrictions and whether there are any differences depending on their nature and drug classes; (b Ascertain whether prescribing restrictions can be added to existing demand-side measures to further enhance prescribing efficiency; (c Whether they compromise subsequent quality of care. RESULTS: Prescribing restrictions have a variable impact on subsequent utilisation of patented protected products versus generics in a class, with their influence depending on the nature and follow-up of the restrictions rather than the class of drug. This is seen among the proton pump inhibitors, statins, and renin-angiotensin drugs. Prescribing restrictions can be successfully added to existing measures to further enhance prescribing efficiency, and do not appear to compromise subsequent quality of care. CONCLUSIONS: Prescribing restrictions can be a successful strategy as countries strive to maintain the European ideals for healthcare. However, care is needed when planning these programmes: else health authorities could be disappointed with their outcome.

    Surveillance of physicians' prescribing patterns and the accumulation and sale of these data for pharmaceutical marketing are currently the subjects of legislation in several states and action by state and national medical associations. Contrary to common perception, the growth of the health care information organization industry has not been limited to the past decade but has been building slowly over the past 50 years, beginning in the 1940s when growth in the prescription drug market fueled industry interest in understanding and influencing prescribing patterns. The development of this surveillance system was not simply imposed on the medical profession by the pharmaceutical industry but was developed through the interactions of pharmaceutical salesmen, pharmaceutical marketers, academic researchers, individual physicians, and physician organizations. Examination of the role of physicians and physician organizations in the development of prescriber profiling is directly relevant to the contemporary policy debate surrounding this issue.

    Blackberry anthocyanins provide attractive color and antioxidant activity. However, anthocyanins degrade during juice processing and storage, so maintaining high anthocyanin concentrations in berry juices may lead to greater antioxidant and health benefits for the consumer. This study evaluated potential additives to stabilize anthocyanins during blackberry juice storage. The anthocyanin stabilizing agents used were: glutathione, galacturonic acid, diethylenetriaminepentaacetic acid and tannic acid, which were added at a level of 500 mg L(-1). Juice anthocyanin, flavonol, and ellagitannin content and percent polymeric color were measured over five weeks of accelerated storage at 30 °C. Glutathione had the greatest protective effect on total anthocyanins and polymeric color. Therefore a second study was performed with glutathione in combination with lipoic and ascorbic acids in an effort to use antioxidant recycling to achieve a synergistic effect. However, the antioxidant recycling system had no protective effect relative to glutathione alone. Glutathione appears to be a promising blackberry juice additive to protect against anthocyanin degradation during storage.

    2010-12-01

    Full Text Available Viticultural practices in the State of Santa Catarina, Brazil, have shown economic growth, with the production of grapes used to produce wines and grape juice. Grapes are rich in phenolic compounds which have drawn attention not only because of their important role in the development of products derived from grapes, but also for their potential beneficial health effects. The objective of this study was to evaluate commercial, organic and homemade grape juices produced in Santa Catarina. Grape juices were analyzed for total phenolic content, colour, and antioxidant activity. The commercial juices had the highest average values for total monomeric anthocyanins and total phenolics. There was a strong positive correlation (R = 0.9566 between the antioxidant activity and total phenolic content for the commercial juice. In addition, the Principle Components Analysis showed a strong positive correlation between the red colour and total monomeric anthocyanins.

    This paper presents the work done within the ESA ESTEC Data Systems Division, targeting the implementation of CFDP in future ESA Science Missions. EUCLID and JUICE currently include CCSDS File Delivery Protocol (CFDP) as baseline for payload data transfer to ground. The two missions have completely different characteristics, although both present quite demanding scenarios. Using the communication link characteristics as an input, some simulations have been performed to optimize the CFDP configuration and get some preliminary figures on the retransmission overhead, payload data bandwidth and number of parallel transactions needed to maintain full bandwidth utilization. The paper provides some guidelines on CFDP configuration and usage that can be useful in future CFDP implementations.

    The objective of this study was to explore the utility of nitrile gloves as a replacement for latex surgical gloves in recovering bacteria from the hands. Two types of nitrile gloves were compared to latex gloves using the parallel streak method. Streaks of Klebsiella pneumoniae and Staphylococcus aureus were made on tryptic soy agar plates, and the zones of inhibition were measured around pieces of glove material placed on the plates. Latex gloves produced a mean zone of inhibition of 0.28 mm, compared to 0.002 mm for nitrile gloves (platex in glove juice sampling methods, since nitrile avoids the risk of latex exposure.

    Objective To report the frequency, types, and causes of errors associated with outpatient computer-generated prescriptions, and to develop a framework to classify these errors to determine which strategies have greatest potential for preventing them. Materials and methods This is a retrospective cohort study of 3850 computer-generated prescriptions received by a commercial outpatient pharmacy chain across three states over 4 weeks in 2008. A clinician panel reviewed the prescriptions using a previously described method to identify and classify medication errors. Primary outcomes were the incidence of medication errors; potential adverse drug events, defined as errors with potential for harm; and rate of prescribing errors by error type and by prescribing system. Results Of 3850 prescriptions, 452 (11.7%) contained 466 total errors, of which 163 (35.0%) were considered potential adverse drug events. Error rates varied by computerized prescribing system, from 5.1% to 37.5%. The most common error was omitted information (60.7% of all errors). Discussion About one in 10 computer-generated prescriptions included at least one error, of which a third had potential for harm. This is consistent with the literature on manual handwritten prescription error rates. The number, type, and severity of errors varied by computerized prescribing system, suggesting that some systems may be better at preventing errors than others. Conclusions Implementing a computerized prescribing system without comprehensive functionality and processes in place to ensure meaningful system use does not decrease medication errors. The authors offer targeted recommendations on improving computerized prescribing systems to prevent errors. PMID:21715428

    The public health spending has now reached very significant levels, in this sense, the responsibility of the medical doctor assumes a significant importance in medical law. The aim of this paper is to analyze the profile of responsibilities of the medical doctor in the light of recent case law. The appropriateness of prescribing and risk assessment are, according to the authors, the real test on which to test the skill, prudence and diligence which are called prescribers. Guidelines can be a valuable tool for the professional help, knowing, however, limits application of the recommendations where to be reconciling with the prevailing protection of personal rights of the user.

    Single cell stimulation in vivo is a powerful tool to investigate the properties of single neurons and their functionality in neural networks. We present a method to determine a cell-specific stimulus that reliably evokes a prescribed spike train with high temporal precision of action potentials. We test the performance of this stimulus in simulations for two different stochastic neuron models. For a broad range of parameters and a neuron firing with intermediate firing rates (20-40 Hz) the reliability in evoking the prescribed spike train is close to its theoretical maximum that is mainly determined by the level of intrinsic noise.

    2016-10-01

    To evaluate contact lens prescribing trends among optometrists in Jordan. Optometrists from 173 practices in Jordan were surveyed about prescribing contact lenses in their practice. Practitioners were required to record information for the last 10 patients that visited their practice. Demographic data such as age and gender was obtained for each patient. In addition, data relating to lens type, lens design, replacement methods and the care regime advised to each patient were recorded. Practitioners were required to provide information relating to their education and years of experience. The influence of education and experience with respect to lens prescribing trends was explored using linear regression models for the proportions of lens types fitted for patients. A total of 1730 contact lens fits were analyzed. The mean (±SD) age of lens wearers was 26.6 (±7.9) years, of whom 65% were female. Conventional hydrogel lenses were the most prescribed lenses, accounting for 60.3% of the fits, followed by silicone hydrogel lenses (31.3%), and rigid lenses (8.4%). In terms of lens design, spherical lenses appeared to be most commonly prescribed on monthly basis. Daily disposable lenses were second most prescribed lens modality, accounting for 20.4% of the study sample. Multi-purpose solution (MPS) was the preferred care regimen, with a prevalence of 88.1% reported in the study sample, compared to hydrogen peroxide (1-step and 2-step), which represented only 2.8% of the patients in this study. A relationship was established between the two educational groups for rigid lens prescribing (F=17.4, ptrends among optometrists in Jordan. Contact lens prescribing in terms of lens type, lens design, modality of wear and care regimen agree with global market trends with small variations. This report will help practitioners and the industry to detect any deficiencies in the contact lens market in Jordan, which will ease implementing current and future plans in developing contact

    Full Text Available Chronic lymphocytic leukemia (CLL is one of the chronic lymphoproliferative disorders (lymphoid neoplasms. It is characterized by a progressive accumulation of functionally incompetent lymphocytes. Patients with leukemia often seek unconventional treatments not prescribed by hematologist in order to improve their cancer treatment outcome or to manage symptoms. In the present report, a 76-year-old patient was diagnosed with B-cell chronic lymphocytic leukemia (B-CLL. Beetroot-carrot juice is used as a complementary and or/ alternative therapy used in conjunction with conventional leukemic treatment (chlorambucil that has been a standard first-line chemotherapeutic agent for patients with CLL and known to have serious and undesirable side-effects. After one month and 15 days of administration of beetroot-carrot juice therapy, the patient had improved appetite, a sense of general well-being and increased vigor daily activities. Furthermore, beetroot-carrot juice was used as an adjuvant to chlorambucil resulted in a substantial reduction in leukocytes and lymphocytes count in peripheral blood and improvement in the relevant biochemical parameters.  Beetroot-carrot juice can be used as an effective treatment for CLL alone or in combination with chlorambucil when taken orally with regular diet on daily basis.

    Borges, Gina; Mullen, William; Crozier, Alan

    2010-10-01

    Thirty six commercial European fruit juices were tested to ascertain their antioxidant capacity and polyphenolic composition. Six of the products were labelled 100% pomegranate juice, the others included 20 brands of diluted pomegranate juice or pomegranate blended with other fruit juices and 10 different non-pomegranate fruit juices. The antioxidant capacity of all the juices was determined while anthocyanin, ellagitannin and ellagic acid profiles of the 26 pomegranate juices and pomegranate juice blends were obtained using HPLC-PDA-MS(2). Additional analysis was conducted on seven of the juices using HPLC with an on-line antioxidant detection system. Three of the "pure" pomegranate juices had the highest ellagitannin content and the highest antioxidant capacity. Only one of these three juices was rich in anthocyanins. The other "pure juices" had differences in their HPLC "pomegranate" fingerprint and also had a lower antioxidant capacity, in some cases lower than that of some of the blended juices. Vitamin C rather than phenolic compounds was the major contributor to the antioxidant capacity for some of the juices. Statistical analysis of both the antioxidant assay and the HPLC on-line antioxidant data demonstrated that the ellagitannins were the major antioxidants in the pomegranate juices. The complexity of the polyphenolic profile of pomegranates necessitates the use of HPLC-PDA-MS(2) for a thorough evaluation of juice composition and authenticity.

    Despite the popularity of dietary nitrate supplementation and the growing evidence base of its potential ergogenic and vascular health benefits, there is no direct information about its effects on exercising limb blood flow in humans. We hypothesized that acute dietary nitrate supplementation from beetroot juice would augment the increases in forearm blood flow, as well as the progressive dilation of the brachial artery, during graded handgrip exercise in healthy young men. In a randomized, double-blind, placebo-controlled crossover study, 12 young (22 ± 2 years) healthy men consumed a beetroot juice (140 mL Beet-It Sport, James White Juice Company) that provided 12.9 mmol (0.8 g) of nitrate or placebo (nitrate-depleted Beet-It Sport) on 2 study visits. At 3 h postconsumption, brachial artery diameter, flow, and blood velocity were measured (Doppler ultrasound) at rest and during 6 exercise intensities. Nitrate supplementation raised plasma nitrate (19.5-fold) and nitrite (1.6-fold) concentrations, and lowered resting arterial pulse wave velocity (PWV) versus placebo (all p nitrate supplementation had no effect on brachial artery diameter, flow, or shear rates at rest (all p ≥ 0.28) or during any exercise workload (all p ≥ 0.18). These findings suggest that acute dietary nitrate supplementation favorably modifies arterial PWV, but does not augment blood flow or brachial artery vasodilation during nonfatiguing forearm exercise in healthy young men.

    Full Text Available The objectives of this study were to develop the method of isotope analysis to quantify the carbon of C3 photosynthetic cycle in pulpy whole apple juice and to measure the legal limits based on Brazilian legislation in order to identify the beverages that do not conform to the Ministry of Agriculture, Livestock and Food Supply (MAPA. This beverage was produced in a laboratory according to the Brazilian law. Pulpy juices adulterated by the addition of sugarcane were also produced. The isotope analyses measured the relative isotope enrichment of the juices, their pulpy fractions (internal standard and purified sugar. From those results, the quantity of C3 source was estimated by means of the isotope dilution equation. To determine the existence of adulteration in commercial juices, it was necessary to create a legal limit according to the Brazilian law. Three brands of commercial juices were analyzed. One was classified as adulterated. The legal limit enabled to clearly identify the juice that was not in conformity with the Brazilian law. The methodology developed proved efficient for quantifying the carbon of C3 origin in commercial pulpy apple juices.

    McNamara, Christopher J; Wiebe, Deborah; Gomez, Margarita

    2011-08-01

    Growth of Alicyclobacillus in low-pH fruit juices may result in off-odors and off-flavors due to the production of compounds such as guaiacol (2-methoxy phenol). An important step in preventing Alicyclobacillus contamination of fruit juices is the screening of incoming ingredients. Many fruit juice concentrates contain compounds that inhibit Alicyclobacillus growth, but beverages produced from the concentrates may not contain sufficient amounts of the active component to prevent spoilage. Therefore, accurate screening of juice concentrates is essential to prevent false-negative test results and product spoilage. The objective of this study was to evaluate isolation methods for detection of Alicyclobacillus in inhibitory juice concentrates. Recovery of Alicyclobacillus spores from inoculated and naturally contaminated concentrates was compared by using pour plate, spread plate, and filtration methods. Pour plates consistently recovered the lowest number of spores from inoculated concentrates. Spread plating was the most effective method used to recover spores from inoculated apple and pomegranate juice concentrates, while filtration resulted in the highest recovery from cranberry concentrate. When tested on naturally contaminated concentrates, the pour plate method failed to detect Alicyclobacillus in many samples. Filtration was much more effective. The filtration method increased the likelihood of detecting Alicyclobacillus contamination of fruit juice concentrates containing inhibitory compounds.

    This study assesses some uses of nutrient-rich juice mechanically extracted from freshly harvested Miscanthus x giganteus (MxG) as part of a green biorefinery system. The juice was used for culturing Saccharomyces cerevisiae and lactic acid bacteria. MxG juice was further used as substrate for fermentation to produce lactic acid using Lactobacillus brevis and Lactobacillus plantarum. The results show that MxG juice was a highly nutritious source for the cultivation of bacteria. Higher concentrations of MxG juice used as culture media, resulted in higher cell growth both aerobically and anaerobically. The highest ethanol yield of 70% theoretical and concentration of 0.75g/100ml were obtained from S. cerevisiae cultivated with 90% (v/v) MxG juice media and used for miscanthus solid fraction fermentation. 11.91g/L of lactic acid was also successfully produced from MxG juice through SSF.

    NONI juice (Morinda citrifolia) is an increasingly popular wellness drink claimed to be beneficial for many illnesses.No overt toxicity has been reported to date. We present two cases of novel hepatotoxicity of NONI juice. Causality of liver injury by NONI juice was asses-sed. Routine laboratory tests and transjugular or percutaneous liver biopsy were performed. The first patient underwent successful liver transplantation while the second patient recovered spontaneously after cessation of NONI juice.A 29-year-old man with previous toxic hepatitis associated with small doses of paracetamol developed sub-acute hepatic failure following consumption of 1.5 L NONI juice over 3 wk necessitating urgent liver transplantation. A 62-year-old woman without evidence of previous liver disease developed an episode of self-limited acutehepatitis following consumption of 2 L NONI juice for over 3 mo. The most likely hepatotoxic components of Morinda citrifolia were anthraquinones. Physicians should be aware of potential hepatotoxicity of NONI juice.

    Full Text Available The content of phenolics: total phenols (TP, flavonoids (TF, anthocyanins (TA and hydroxicinnamic acid as well as the total antioxidant capacity (TAC in nine commercial red fruit juices (sour cherry, black currant, red grape produced in Serbia were evaluated. The total compounds content was measured by spectrophotometric methods, TAC was determined using DPPH assays, and individual anthocyanins and hydroxycinnamic acids was determined using HPLC-DAD methods. Among the examined fruit juices, the black currant juices contained the highest amounts of all groups of the phenolics and exhibited strong antioxidant capacity. The amount of anthocyanins determined by HPLC method ranged from 92.36 to 512.73 mg/L in red grape and black currant juices, respectively. The anthocyanins present in the investigated red fruit juices were derivatives of cyanidin, delphinidin, petunidin, peonidin and malvidin. The predominant phenolic acid was neoclorogenic acid in sour cherry, caffeic acid in black currant, and p-coumaric acid in black grape juices. Generally, the red fruit juices produced in the Serbia are a rich source of the phenolic, which show evident antioxidant capacity.

    The thermal tolerance Cronobacter sakazakii was examined in sterile powdered infant formula (PIF) rehydrated at 58 °C in water or apple juice supplemented with vanillin, ethyl vanillin, or vanillic acid. All three compounds decreased thermal tolerance during-rehydration and the lowest decimal reduction time (D-value, 0.19 ± 0.01 min) was measured in PIF rehydrated in apple juice supplemented with 20 mM vanillic acid. At this level of supplementation no C. sakazakii were detected in PIF stored for 48 h at 10 and 24 h at 21 °C subsequent to a sublethal heat treatment. Thermal tolerance during rehydration and survival in reconstituted PIF were influenced by compound type, concentration, and temperature. Supplementation of PIF with vanillin, ethyl vanillin, or vanillic acid could enhance the safety of PIF or other dehydrated foods contaminated with C. sakazakii.

    The role of socio-economic status (SES) in fruit juice and fruit drink consumption is not well understood in a Canadian context. This study examines the relationship between SES and Canadian fruit juice and fruit drink consumption. The Canadian Community Health Survey (2011-2012), a cross-sectional survey that employs multistage cluster sampling, provided relevant data for a sample of 103 125 Canadians, aged 12 and older, living in the 10 provinces. Household income level decile, ranked at the health region level, was used as a surrogate measure of SES. Fruit juice and fruit drink consumption data were collected via self-report in telephone/in-person interviews. Multivariable gamma regression was used to model the relationship between SES and frequency of fruit juice and fruit drink consumption, adjusting for age, sex, diabetes status, daily fruit and vegetable consumption, education level, racial identity and physical activity. A negative relationship was found, with a decreasing daily rate of fruit juice and fruit drink consumption associated with increasing SES. In the adjusted model, Canadians in the lowest SES category consumed fruit juice and fruit drinks at an average daily rate 1.18 times (95% CI: 1.14-1.23) that of Canadians in the highest SES category. The negative association between health region-adjusted SES and fruit juice and fruit drink consumption highlights the potentially important role of socio-economic factors at a local level. Canadian policy that aims to lower fruit juice and fruit drink consumption, and thus sugar intake, should target financial avenues (such as making fruit juice less financially attractive by lowering the cost of whole fruit and vegetables) in addition to communicating health benefits.

    The effects of juice matrix and pasteurization on the stability of total phenols and especially total and individual anthocyanins were examined in black currant (BC) juice and mixtures with apple, persimmon, and peach juices at 4 °C and 20 °C. Total phenol content decreased in all juices at both temperatures but there was a trend to lower levels in unpasteurized over pasteurized juices. Differences in the decline of total anthocyanins between pasteurized and unpasteurized juices varied according to the juice type and the storage temperature. At 4 °C storage, anthocyanins declined in all juices according to pseudo 1st-order kinetics and there were only small differences in the rates between pasteurized and unpasteurized juices. However, at 20 °C, although pasteurized and unpasteurized BC juices and pasteurized mixed juices followed pseudo 1st-order kinetics, there was a different pattern in unpasteurized mixed juices; a rapid initial decline was followed by a slowing down. The effect of the added juice on anthocyanin decline was also different at either temperature. At 4 °C, the anthocyanins decreased faster in mixed juices than BC juice alone, but at 20 °C, at least in pasteurized mixed juices, the decline was similar or even slower than in BC juice; there were only small differences among the 3 mixed juices. At 20 °C, in pasteurized and unpasteurized BC juices, the rate of decrease was essentially the same for all 4 individual anthocyanins but in the mixed juices the 2 glucosides decreased significantly faster than the 2 rutinosides. © 2016 Institute of Food Technologists®.

    Full Text Available Sugarcane juice with passion fruit pulp was clarified using microfiltration under different T (temperature, P (pressure, and V (tangential velocity. The effects of these processing parameters were evaluated applying a rotational central composite experimental design (RCCD and response surface methodology (RSM. The tests were performed at a filtration pilot plant using a polyamide hollow-fiber membrane with an average pore diameter of 0.4 µm and filtration area of 0.723 m². In addition, the resistances to the permeate flux during the microfiltration were investigated according to the series resistance. The final permeate flux ranged from 7.05 to 17.84 L·h- 1·m- 2. There was a rapid decline in flux (50% in the initial stages of microfiltration. T and V were the major variables responsible for the flux increase. The concentration polarization showed the greatest influence on the flux decline, and highest values for the flux decline rate (λ were found when low pressures were used. In the clarified juice there was a reduction in the contents of total solids, proteins, vitamin C, and acidity, while the soluble solids, pH, and ash contents did not change. Finally, membrane process could produce high quality filtered sugarcane juice with substantial flux and increased luminosity improving organoleptical properties.

    Fruit and vegetable juices are used due to convenience. The juices are rich in various minerals, vitamins, and other nutrients. To process the juices and their clarification and/or concentration is required. The membranes are being used for these purposes. These processes are preferred over others because of high efficiency and low temperature. Membranes and their characteristics have been discussed in brief for knowing suitability of membranes for fruit and vegetable juices. Membrane separation is low temperature process in which the organoleptic quality of the juice is almost retained. In this review, different membrane separation methods including Microfiltration, Ultrafiltration, and Reverse osmosis for fruit juices reported in the literature are discussed. The major fruit and vegetable juices using membrane processes are including the Reverse osmosis studies for concentration of Orange juice, Carrot juice, and Grape juice are discusses. The Microfiltration and Ultrafiltration are used for clarification of juices of mosambi juice, apple juice, pineapple juice, and kiwifruit juice. The various optimized parameters in membranes studies are pH, TAA, TSS, and AIS. In this review, in addition to above the OD is also discussed, where the membranes are used.

    Poly(β-l-malic acid) (PMA) is a biodegradable polymer with many potential biomedical applications. PMA can be readily hydrolyzed to malic acid (MA), which is widely used as an acidulant in foods and pharmaceuticals. PMA production from sucrose and sugarcane juice by Aureobasidium pullulans ZX-10 was studied in shake-flasks and bioreactors, confirming that sugarcane juice can be used as an economical substrate without any pretreatment or nutrients supplementation. A high PMA titer of 116.3g/L and yield of 0.41g/g were achieved in fed-batch fermentation. A high productivity of 0.66g/L·h was achieved in repeated-batch fermentation with cell recycle. These results compared favorably with those obtained from glucose and other biomass feedstocks. A process economic analysis showed that PMA could be produced from sugarcane juice at a cost of $1.33/kg, offering a cost-competitive bio-based PMA for industrial applications.

    2012-05-01

    Full Text Available Abstract Background Information about antibiotic prescribing practice in primary care is not available for Ireland, unlike other European countries. The study aimed to ascertain the types of antibiotics and the corresponding conditions seen in primary care and whether general practitioners (GPs felt that an antibiotic was necessary at the time of consultation. This information will be vital to inform future initiatives in prudent antibiotic prescribing in primary care. Methods Participating GPs gathered data on all antibiotics prescribed by them in 100 consecutive patients’ consultations as well as data on the conditions being treated and whether they felt the antibiotic was necessary. Results 171 GPs collected data on 16,899 consultations. An antibiotic was prescribed at 20.16% of these consultations. The majority were prescribed for symptoms or diagnoses associated with the respiratory system; the highest rate of prescribing in these consultations were for patients aged 15–64 years (62.23%. There is a high rate of 2nd and 3rd line agents being used for common ailments such as otitis media and tonsillitis. Amoxicillin, which is recommended as 1st line in most common infections, was twice as likely to be prescribed if the prescription was for deferred used or deemed unnecessary by the GP. Conclusion The study demonstrates that potentially inappropriate prescribing is occurring in the adult population and the high rate of broad-spectrum antimicrobial agents is a major concern. This study also indicates that amoxicillin may be being used for its placebo effect rather than specifically for treatment of a definite bacterial infection.

    2010-01-01

    The purpose of this study was to gain understanding about nurse practitioners' (NPs') prescriptive decision making for geriatric patients with attention to pharmaceutical marketing influences. Prior research has focused on physician prescribers and identified suboptimal practices. Because the majority of medications are prescribed to older adults, NPs in geriatric practice were targeted as an information-rich group to interview about prescribing issues. Given the exploratory nature of this research, qualitative focus group methods were employed using content analysis. Fifteen NPs were recruited at an annual national geriatric NP conference. They worked in all regions of the United States, had an average of 9 years prescribing experience, and participated in 1 of the 2 focus groups. The key theme that emerged was that they were more than a prescriber. Findings revealed overwhelming consistency among the NP participants that their nursing background instilled a holistic approach that encompassed both nondrug and therapeutic drug options and skepticism about drug marketing, as well as offered a positive difference by tailoring to their patients' biophysical, psychological, and economic needs with an involvement in the interplay of geriatric care issues not typically addressed by physicians. The participants' reported approaches were in alignment with geriatric prescribing recommendations.

    2001-01-01

    The methods used to isolate volatile compounds for GC analyses can cause profound effects on the quantitative and qualitative composition of the injected sample, and exert a great influence in the resultant bioactivity of volatiles. Especially with plant tissues like tomatoes, the isolation of volatile constituents using classical methods may yield results which are not representative of the chemicals present in the natural material. Headspace sampling methods may be advantageous in capturing the same volatile compounds emitted from tomatoes that are detected by the human nose. This study utilized an extremely sensitive dynamic headspace sampling with thermal desorption method to determine volatile components of fresh tomato juices. The method proved very sensitive for the isolation of tomato volatiles and concentrations of flavor compounds were much greater than related literature studies.

    Full Text Available Market offer of vegetable juices in Europe is growing, and the vegetable species and processing technologies used become more diversified resulting in a large range of juice types. At the same time consumers look for natural and safe products with pro-health properties. The aim of this study was to evaluate the nutritional composition of selected juices based on beetroots coming from different agricultural systems and processed according to different technologies. Research material consisted of conventional and organic juices marketed in Poland, in that pure pressed juices, fermented juice and juices from concentrate, pure and combined with apple or lemon juice. The concentration of vitamin C, organic acids, total and reducing sugars, phenolic acids, flavonoids and betalains has been determined in the juices. All beetroot juices were abundant in betalains, with higher concentrations of these compounds found in pure beetroot juices when compared to juices combined with apple or lemon. Highest concentration of betanin-3-O-glucoside was found in pure conventional juice from concentrate, while highest betanidin content was found in pure organic fermented juice. Highest vitamin C contents were found in pressed organic juices combined with apple and lemon. All juices were abundant in polyphenols, mainly phenolic acids, with highest concentrations of these antioxidants found in conventional pure pressed juice. The study shows that beetroot juices, independently on the beetroot processing technology and agricultural production system, are very valuable products due to the presence of numerous bioactive compounds, especially betalains, in their composition. Therefore beetroot juice consumption should be promoted among consumers.

    Full Text Available Mª Rosa Güell RousDepartament de Pneumologia, Hospital de la Santa Creu I de Sant Pau, Barcelona, SpainAbstract: Long-term oxygen therapy (LTOT is the treatment proven to improve survival in chronic obstructive pulmonary disease (COPD patients with chronic respiratory failure. It also appears to reduce the number of hospitalizations, increase effort capacity, and improve health-related quality of life. Standard LTOT criteria are related to COPD patients who have PaO2 <60 mmHg, are in a clinical stable situation, and are receiving optimal pharmacological treatment. According to LTOT guidelines, oxygen should be prescribed for at least 18 hours per day although some authors consider 24 hours would be more beneficial. The benefits of LTOT depend on correction of hypoxemia. Arterial blood gases should be measured at rest. During exercise, an effort test should be done to assure adequate SaO2. During sleep, continuous monitoring of SaO2 and PaCO2 should be performed to confirm correction of SaO2 overnight. An arterial blood gas sample should be taken at awakening to assess PaCO2 in order to prevent hypoventilation from the oxygen therapy. Several issues that need to be addressed are the use of LTOT in COPD patients with moderate hypoxemia, the efficacy of LTOT in patients who desaturate during exercise or during sleep, the optimal dosage of oxygen supplementation, LTOT compliance, and the LTOT prescription in diseases other than COPD.Keywords: long-term oxygen therapy, COPD, oxygen supplementation, chronic respiratory failure, hypoxemia

    2016-10-01

    Full Text Available Natural fruit juices are difficult to transform into powder because they are rich in sugars and acids with low glass transition temperatures, resulting in a sticky behaviour during spray drying. The present research work aimed to test the prebiotics maltodextrin and arabic gum as drying agents in order to be able to produce dehydrated powder from pineapple, strawberry and apple juices. 2 % of maltodextrin and an inlet air temperature of 130 °C are recommended to spray dry apple juice, reaching 60 % yield of powder with a water activity below 0.40. For strawberry juice, 2 % of this carrier is recommended and the inlet air temperature, 120 °C or 130 °C, did not seem relevant. For pineapple, neither the concentration of the carrier nor the inlet air temperature seemed to be relevant.

    The main cause of spray drying is to increase the shelf life and easy handling of juices. In the present paper, the studies carried out so far on spray drying of various fruits and vegetables are reported. The major fruit juices dried are mango, banana, orange, guava, bayberry, watermelon, pineapple, etc. However, study on vegetable juices is limited. In spray drying, the major optimized parameters are inlet air temperature, relative humidity of air, outlet air temperature, and atomizer speed that are given for a particular study. The juices in spray drying require addition of drying agents that include matlodextrin, liquid glucose, etc. The drying agents are added to increase the glass transition temperature. Different approaches for spray dryer design have also been discussed in the present work.

    Combinatorial peptide ligand library technology, coupled to mass spectrometry, has been applied to extensively map the proteome of orange pulp and peel and, via this fingerprinting, to detect its presence in commercial orange juices and drinks. The native and denaturing extraction protocols have captured 1109 orange proteins, as identified by LC-MS/MS. This proteomic map has been searched in an orange concentrate, from a Spanish juice manufacturer, as well as in commercial orange juices and soft drinks. The presence of numerous orange proteins in commercial juices has demonstrated the genuineness of these products, prepared by using orange fruits as original ingredients. However, the low number of identified proteins in sparkling beverages has suggested that they were prepared with scarce amounts of fruit extract, thus imparting lower quality to the final products. These findings not only increase the knowledge of the orange proteome but also present a reliable analytical method to assess quality and genuineness of commercial products.

    Full Text Available Passion fruit is widely consumed due to its pleasant flavour and aroma acidity, and it is considered very important a source of minerals and vitamins. It is used in many products such as ice-cream, mousses and, especially, juices. However, the processing of passion fruit juice may modify the composition and biodisponibility of the bioactive compounds. Investigations of the effects of processing on nutritional components in tropical juices are scarce. Frequently, only losses of vitamin C are evaluated. The objective of this paper is to investigate how some operations of passion fruit juice processing (formulation/homogeneization/thermal treatment affect this product's chemical and physicochemical characteristics. The results showed that the chemical and physicochemical characteristics are little affected by the processing although a reduction in vitamin C contents and anthocyanin, large quantities of carotenoids was verified even after the pasteurization stage.

    Full Text Available The aim of this study is testing black grape juice as a radiomodifier against whole body X-irradiation using an animal model. Sixteen male Wistar rats were divided into four groups where two were irradiated by X-rays from a 200 kV machine specially designed to biological samples. Animals were fed ad libitum and drank voluntarily 2-10 ml a day of grape juice or placebo (isocaloric glucose and fructose solution for one week before and two weeks after 6 Gy X-irradiation when they were sacrificed. Results have shown a significant liver weight loss in irradiated placebo group only while grape juice one has presented no losses. Hematological analysis showed typical abnormalities for ionizing radiation exposure, including early leucopenia and anemia. The intake of grape juice induced an increase in granulocyte percent count.El propósito de este estudio fue comprobar el efecto radiomodificador del mosto tinto de uva frente a irradiación de cuerpo entero con rayos X usando un modelo animal. Dieciséis ratas macho de raza Wistar fueron irradiadas mediante un aparato de 200 kV diseñado específicamente para muestras biológicas. Los animales fueron alimentados ad libitum y bebieron cada dia voluntariamente entre 2 y 10 ml de mosto de uva o placebo (solución isocalórica de glucosa y fructosa durante una semana antes y dos semanas después de irradiación con rayos X a una dosis de 6 Gy, momento en que fueron sacrificadas. Los resultados mostraron una pérdida significativa de peso hepático en los animales irradiados tratados con placebo, mientras que los tratados con mosto presentaron valores similares a los controles no irradiados. El análisis hematológico presentó las anomalías típicas de la exposición a radiación ionizante, con disminución leucocitaria temprana y anemia. La ingestión de mosto de uva indujo un aumento del porcentaje de granulocitos.

    Full Text Available Abstract Background The shift away from a biological science to a social science model of nursing care has resulted in a reduction in pharmacology knowledge and understanding in pre-registration nursing students. This has a significant impact on nurse prescribing training where pharmacology is a critical component of the course from a patient safety perspective. Methods Reusable learning objects (RLOs are electronic resources based on a single learning objective which use high quality graphics and audio to help engagement with the material and to facilitate learning. This study used questionnaire data from three successive cohorts of nurse prescribing students (n = 84 to evaluate the use of RLOs focussed around pharmacology concepts to promote the understanding of these concepts in students. A small number of students (n = 10 were followed up by telephone interview one year after qualification to gain further insight into students' perceptions of the value of RLOs as an educational tool. Results Students' perceptions of their own understanding of pharmacology concepts increased substantially following the introduction of RLOs to supplement the pharmacology component of the course. Student evaluation of the RLOs themselves was extremely positive with a number of students continuing to access these tools post-qualification. Conclusion The use of RLOs to support the pharmacology component of nurse prescribing courses successfully resulted in a perceived increase in pharmacology understanding, with some students directly implicating these educational tools in developing confidence in their own prescribing abilities.

    Full Text Available ABSTRACT: Wine is one of the end products of fermentation of respiratory substrates, while, yeast is one of the principal fermenting microorganisms. Changes in the substrate composition and yeast strains could vary in the quality of the wine. Two yeast isolates (Y4 and Y7 from date palm juice and standard yeast “Y33”,an isolate of Saccharomyces cerevisiae (MTCC-170 from Institute of MicrobiAl Technology, IMTECH, Chandigarh where used for studying the comparative fermentation of Molasses without nutrient supplementation, and separately with nutrient supplementation by KH2PO4 and NaNO3 @ 1g/l. Though, with nutrient supplement KH2PO4, Y33 yields higher alcohol%, both Y4 and Y7 strains produce wine with better efficiency and acceptability without the nutrient supplements unlike Y33 strains. All the three strains impart better flavour and colour in the medium without nutrient supplement in terms of hedonic scale. Further, Y4 yields higher alcohol than Y7 and Y33. Therefore, palm juice yeast isolates particularly, Y4 strains show the highest overall fermentation efficiency and acceptability among the three yeasts isolates, moreover, since its highest efficiency occurs in the absence of nutrient supplementation, unlike the standard strain, it can be recommendedas a better substitute of the standard Y33 strains. KEY WORDS: Fermentation, Yeast,  Nutrient supplements.

    Full Text Available It is now known that vitamin D deficiency is a worldwide health problem. In our country, as food fortification is lacking, supplementation with pharmaceutical preparations is the only means of treatment of vitamin D deficiency. We aimed to study the composition and availability of various vitamin D preparations in the Indian market, data about which was collected from annual drug compendium. The preparations were assessed for total number, different formulations, constituents and amount of each constituent present in the formulation. Vitamin D3 is available in the form of cholecalciferol, alfacalcidiol and calcitriol as single ingredient products and in combination with calcium and other micronutrients. Most of the supplements contain calcitriol (46.5% or alfacalcidiol (43% as tablets (51.1% and capsules (35.2%. Cholecalciferol, the preferred form for prophylaxis and treatment of vitamin D deficient states, constitutes only 10% of the available market preparations. High market sales of calcium supplements containing calcitriol indicate increasing intake of calcitriol rather than cholecalciferol; which could predispose to toxicity. There is a need for marketing and rational prescribing of the appropriate vitamin D supplement in ostensibly healthy Indian population. Implementation of population-based education and intervention programmes with enforcement of strict regulations could generate awareness and curb unsupervised intake of vitamin D containing dietary supplements. This health challenge mandates effective nutritional policies, fortification and supplementation programmes and partnership between government, healthcare and industry to safeguard the health of Indian population at large.

    The aporia is obvious: food supplement, classified and regulated by food law, sometimes have the characteristics and the typical effects of medicines. In addition, these are produced by pharmaceutical companies and, through the scientific officer, are prescribed by doctors and dispensed by pharmacies. This study will attempt to retrace the winding, and sometimes overlapping, regulatory pathways of the legislation on food supplement, food and medicines. It will be important object the particular application of the precautionary principle behind the legislation on food supplement: application "in posterior", so the controls on the purity of the product and the possible effects resulting from the assumption is carried out ex post trade. So we try to disentangle the intricate legislation with the national (and European) Court contributions. In particular, after a brief analysis of the rulings of the Competition and Market Authority on misleading advertising and by the Supreme Court in relation to crimes against health damage, it will come to the analysis of interpretative problems of a purely criminal law nature, in light of the recent proposal for reform about agribusiness crimes. Finally, it will be inevitable to analyze briefly the recent implementation of the d.lgs. n. 17/2004 concerning the distance trade of non-prescription medicines. There is no doubt that now, internet represents the preferred distribution channel for pharmaceutical products (including food supplement) and the most tempting "place" (because of control difficulties) for the realization of criminal conduct. The conclusion will be that the need to achieve more targeted and homogeneous regulatory measures, while also having to protect - public and individual - health through the protection of the legal security in one with the protection of the right to information.

    Tomato is a globally famous food and contains several phytonutrients including lycopene, β-carotene, anthocyanin, and flavonoids. The increased temperature used to produce tomato juice, ketchup, tomato paste and canned tomato enhances the bioactive composition. We aimed to verify the beneficial effects of processed tomato juice from Kagome Ltd. (KOT) on hypolipidemic action in hamsters with hyperlipidemia induced by a 0.2% cholesterol and 10% lard diet (i.e., high-cholesterol diet (HCD)). Male Golden Syrian hamsters were randomly divided into two groups for treatment: normal (n = 8), standard diet (control); and experimental (n = 32), HCD. The 32 hamsters were further divided into four groups (n = 8 per group) to receive vehicle or KOT by oral gavage at 2787, 5573, or 13,934 mg/kg/day for six weeks, designated the HCD-1X, -2X and -5X groups, respectively. The efficacy and safety of KOT supplementation was evaluated by lipid profiles of serum, liver and feces and by clinical biochemistry and histopathology. HCD significantly increased serum levels of total cholesterol (TC), triacylglycerol (TG), high-density lipoprotein cholesterol (HDL-C), and low-density lipoprotein cholesterol (LDL-C), LDL-C/HDL-C ratio, hepatic and fetal TC and TG levels, and degree of fatty liver as compared with controls. KOT supplementation dose-dependently decreased serum TC, TG, LDL-C levels, LDL-C/HDL-C ratio, hepatic TC and TG levels, and fecal TG level. Our study provides experiment-based evidence to support that KOT may be useful in treating or preventing the onset of hyperlipidemia. PMID:26694461

    The search for new antimicrobial compounds is ongoing. Its importance cannot be overemphasized in an era of emerging resistant pathogenic organisms. This study therefore investigated the phytochemical composition and antioxidant and antimicrobial activities of different citrus juice concentrates. Fruit juices of Citrus tangerine (tangerine), Citrus paradisi (grape), Citrus limon (lemon), and Citrus aurantifolia (lime) were evaluated. Antimicrobial activities against five bacterial and three fungal strains were evaluated. The results revealed the presence of alkaloids, flavonoids, steroids, terpenoids, saponins, cardiac glycosides, and reducing sugars in all the juice concentrates. DPPH (1,1-diphenyl-2-picrylhydrazyl) radical scavenging capacities varied with tangerine and grape juices having better scavenging capacities than lemon and lime juices. Grape juice was observed to have a significantly higher (P < 0.05) ferric-reducing antioxidant potential (FRAP) value (364.2 ± 10.25 μmol/L Fe(II)/g of the extract) than the reference antioxidant, ascorbic acid (312.88 ± 5.61 μmol/L). Antimicrobial studies revealed differential antimicrobial activities against different microbial strains. Zones of inhibition ranging from 4 to 26 mm were observed for the antibacterial tests with 0-24 mm for antifungal test. Minimum inhibitory concentrations (MIC) and minimum bacteriostatic concentrations (MBC) for concentrates against bacterial strains ranged from 12.5 to 200 μg/mL. Lemon and lime juice concentrates had lower MIC and MBC values with orange and tangerine having the highest values. Minimum fungicidal concentrations ranged from 50 to 200 μg/mL. The results of this study suggest that these juice concentrates may have beneficial antimicrobial roles that can be exploited in controlling unwanted microbial growth.

    Total fruit intake in the United States is ~1 cup equivalent per day, or one-half of the 2010 Dietary Guidelines for Americans recommendation for adults. Two-thirds of the fruit consumed is whole fruit and one-third is 100% juice. The nutritional value of whole fruit, with the exception of fiber and vitamin C, may be retained with appropriate juice production methods and storage conditions. One-hundred percent fruit juice consumption is associated with a number of health benefits, such as improved cardiovascular health and decreased obesity, although some of these and other potential benefits are controversial. Comprehensive analyses of the evidence by the Academy of Nutrition and Dietetics in 2014, the US Dietary Guidelines Advisory Committee in 2010, and the Australian Dietary Guidelines of 2013 concluded that 100% fruit juice is not related to adiposity in children when consumed in appropriate amounts for age and energy needs. However, some reports suggest the consumption of fruit juice contributes to unhealthful outcomes, particularly among children. A dietary modeling study on the best ways to meet the fruit intake shortfall showed that a combination of whole fruit and 100% juice improved dietary density of potassium and vitamin C without significantly increasing total calories. Notably, 100% juice intake was capped at amounts consistent with the 2001 American Pediatric Association guidance. The preponderance of evidence supports the position that 100% fruit juice delivers essential nutrients and phytonutrients, provides year-round access to a variety of fruits, and is a cost-effective way to help people meet fruit recommendations.

    AIM:To establish if the juice of Moro,an anthocyaninrich orange,may improve liver damage in mice with diet-induced obesity.METHODS:Eight-week-old mice were fed a high-fat diet (HFD) and were administrated water or Moro juice for 12 wk.Liver morphology,gene expression of lipid transcription factors,and metabolic enzymes were assessed.RESULTS:Mice fed HFD displayed increased body weight,insulin resistance and dyslipidemia.Moro juice administration limited body weight gain,enhanced insulin sensitivity,and decreased serum triglycerides and total cholesterol.Mice fed HFD showed liver steatosis associated with ballooning.Dietary Moro juice markedly improved liver steatosis by inducing the expression of peroxisome proliferator-activated receptor-a and its target gene acylCoA-oxidase,a key enzyme of lipid oxidation.Consistently,Moro juice consumption suppressed the expression of liver X receptor-o and its target gene fatty acid synthase,and restored liver glycerol-3-phosphate acyltransferase 1 activity.CONCLUSION:Moro juice counteracts liver steatogenesis in mice with diet-induced obesity and thus may represent a promising dietary option for the prevention of fatty liver.

    Full Text Available Sugarcane is an important economic crop in southwest Japan, but its production is decreasing. To increase sugar production, both sugarcane yield and quality should be improved. Fertilizer management is one of the factors that influence sugarcane quality. We accordingly focused on nutrients present in sugarcane juice and attempted to identify the key factors affecting sugarcane quality. We collected sugarcane samples from 2013 to 2015 from all of the sugar mills in Japan and examined the relationships between juice nutrients and sucrose concentration. Juice analysis over 3 year showed that potassium (K+ and chloride (Cl− were the most abundant cation and anion in the juice and that both negatively correlated with the sucrose concentration. K+ and Cl− concentrations significantly varied depending on production areas and those with higher K+ and Cl− concentrations had a low sucrose concentration. This finding suggests that sugarcane in those areas may have been supplied with these two ions in excess. Electrical conductivity (EC in the juice always positively correlated with K+ and Cl− concentrations. EC may thus be a reliable indicator of K+ and Cl− concentrations and could be used for nutrient diagnosis because of its ease of measurement. For improving sugarcane quality, we recommend that potassium chloride, which supplies both K+ and Cl− and is a commonly used potassium fertilizer for sugarcane production in Japan, should be used in lower quantities in a year following one in which the EC of sugarcane juice at harvest is found to be high.

    To develop evidence-based hypoglycemia treatment protocols in patients receiving total enteral nutrition, this study determined the effect on enteral tube flow of glucose therapy agents: apple juice, orange juice, and cola, and it also examined the effects of tube type and feed type with these glucose therapy agents. For this study, 12 gastrostomy tubes (6 polyethylene and 6 silicone) were set at 50 mL/h. Each feeding set was filled with Isosource HN with fibre or Novasource Renal. Each tube was irrigated with 1 glucose therapy agent, providing approximately 20 g of carbohydrate every 4 h. Flow-rate measurements were collected at 2 h intervals. The results showed that the glucose therapy agent choice affected flow rates: apple juice and cola had higher average flow rates than orange juice (P = 0.01). A significant difference was found between tube type and enteral formula: polyethylene tubes had higher average flow rates than silicone tubes (P rates than Novasource Renal (P = 0.01). We concluded that apple juice and cola have less tube clogging potential than orange juice, and thus may be considered as primary treatment options for hypoglycemia in enterally fed patients. Polyethylene tubes and Isosource HN with fibre were less likely to clog than silicone tubes and Novasource Renal.

    Browning tends to occur in grape juice during processing and storage and decreases the commercial value of it. Thus, browning inhibition is an important objective for manufacturers. This study aims to investigate the efficacy of glutathione as a browning inhibitor for use on grape juice. Grape juice browning treated with glutathione was monitored during processing and accelerated browning. 0.04% of glutathione inhibited 99.4% of the polyphenoloxidase activity in the grape juice. Consequently, during processing at room temperature and accelerated browning at 80 °C, the browning in the grape juice treated with glutathione was significantly lower than that in the control (pbrowning inhibitor used in grape juice.

    Prescribed burning is highly uncommon in the Netherlands, where wildfire awareness is increasing but its risk management does not yet include fuel management strategies. A major exception is on two military bases, that need to burn their fields in winter and spring to prevent wildfires during summer shooting practice. Research on these very frequent burns has so far been limited to effects on biodiversity, yet site managers and policy makers have questions regarding the soil temperatures reached during these burns because of potential impact on soil properties and soil dwelling fauna. In March 2015, I therefore measured soil and litter temperatures under heath and grass vegetation during a prescribed burn on military terrain in the Netherlands. Soil and litter moisture were sampled pre- and post-fire, ash was collected, and fireline intensity was estimated from flame length. While standing vegetation was dry (0.13 g water/g biomass for grass and 0.6 g/g for heather), soil and litter were moist (0.21 cm3/cm3 and 1.6 g/g, respectively). Soil heating was therefore very limited, with maximum soil temperature at the soil-litter interface remaining being as low as 6.5 to 11.5°C, and litter temperatures reaching a maximum of 77.5°C at the top of the litter layer. As a result, any changes in physical properties like soil organic matter content and bulk density were not significant. These results are a first step towards a database of soil heating in relation to fuel load and fire intensity in this temperate country, which is not only valuable to increase understanding of the relationships between fire intensity and severity, but also instrumental in the policy debate regarding the sustainability of prescribed burns.

    Juice blends made from the mixture of snake tomato (Trichosanthes cucumerina) and Pineapple (Ananas comosus) fruits were analyzed for pH, antioxidant properties, total titratable acidity, vitamin C, lycopene and total phenolic contents after different blend ratios were made. The addition of snake tomato juice increased the vitamin C, total carotene, lycopene and antioxidant properties of the juice blends. The radical scavenging properties of juice blends containing a higher ratio of snake tomato were higher and samples stored at room temperature (29°C) showed an increase in antioxidant properties compared to samples stored at 4°C. In conclusion, snake tomato juice up to 50% may be added to Pineapple juice to make a healthy juice blend. Copyright © 2016 Elsevier Ltd. All rights reserved.

    Full Text Available Abstract Background The rationale for use of drugs during pregnancy requires a careful assessment as in addition to the mother, the health and life of her unborn child is also at stake. Information on the use of drugs during pregnancy is not available in Pakistan. The aim of this study was to evaluate the patterns of drug prescriptions to pregnant women in tertiary care hospitals of Pakistan. Methods This was a cross-sectional study conducted at five tertiary care hospitals of Pakistan. Copies of outpatient medicinal prescriptions given to pregnant patients attending the antenatal clinics were collected. The drugs were classified according to the pharmacological class and their teratogenic potential. Results All the pregnant women attending the antenatal clinics received a prescription containing at least one drug. A total of 3769 distinct prescriptions given to different women were collected. Majority of the women who received the prescriptions belonged to third trimester (55.4% followed by second (33.6% and first trimester (11.0%. On an average, each prescription contained 1.66 ± 0.14 drugs. The obstetricians at Civil Hospital, Karachi and Chandka Medical College Hospital, Larkana showed a tendency of prescribing lesser number of drugs compared to those in other hospitals. Anti-anemic drugs including iron preparations and vitamin and mineral supplements (79.4% were the most frequently prescribed drugs followed by analgesics (6.2% and anti-bacterials (2.2%. 739 women (19.6% received prescriptions containing drugs other than vitamin or mineral supplements. Only 1275 (21.6% of all the prescribed drugs (n = 6100 were outside this vitamin/mineral supplement class. Out of these 1275 drugs, 29 (2.3% drugs were prescribed which are considered to be teratogenic. Misoprostol was the most frequently prescribed (n = 6 among the teratogenic drugs followed by carbimazole (n = 5 and methotrexate (n = 5. Twenty nine pregnant women (0.8% of all the women

    Patulin is the most common mycotoxin found in apples and apple juices. The objective of this study was to determine the concentrations of patulin in (i) apple cider produced and marketed by Michigan apple cider mills during the fall seasons of 2002 to 2003 and 2003 to 2004 and (ii) apple juice and cider, including shelf-stable products, marketed in retail grocery stores in Michigan throughout 2005 and 2006. End product samples (n=493) obtained from 104 Michigan apple cider mills were analyzed for patulin concentration by using solid-phase extraction followed by high-performance liquid chromatography. Patulin was detected (> or =4 microg/liter) in 18.7% of all cider mill samples, with 11 samples (2.2%) having patulin concentrations of > or =50 microg/liter. A greater percentage of cider samples obtained from mills using thermal pasteurization contained detectable patulin (28.4%) than did those from mills using UV light radiation (13.5%) or no pathogen reduction treatment (17.0%). Among retail grocery store samples (n=159), 23% of apple juice and cider samples contained detectable patulin, with 18 samples (11.3%) having patulin concentrations of > or =50 microg/liter. The U.S. Food and Drug Administration (FDA) action level for patulin is 50 microg/kg. Some apple juice samples obtained from retail grocery stores had exceptionally high patulin concentrations, ranging up to 2700 microg/liter. Collectively, these results indicate that most apple cider and juice test samples from Michigan were below the FDA action level for patulin but that certain apple cider and juice processors have inadequate controls over patulin concentrations in final products. The industry, overall, should focus on improved quality of fruit used in juice production and improve culling procedures to reduce patulin concentrations.

    Outbreaks of illness associated with consumption of fruit juice have been a growing public health problem since the early 1990s. In response to epidemiologic investigations of outbreaks in which juice was implicated, the U.S. Food and Drug Administration implemented process control measures to regulate the production of fruit juice. The final juice regulation, which became effective in 2002, 2003, and 2004, depending on the size of the business, requires that juice operations comply with a hazard analysis critical control point (HACCP) plan. The Centers for Disease Control and Prevention (CDC) receives reports of food-associated outbreaks of illness. We reviewed fruit juice-associated outbreaks of illness reported to the CDC's Foodborne Outbreak Reporting System. From 1995 through 2005, 21 juice-associated outbreaks were reported to CDC; 10 implicated apple juice or cider, 8 were linked to orange juice, and 3 involved other types of fruit juice. These outbreaks caused 1,366 illnesses, with a median of 21 cases per outbreak (range, 2 to 398 cases). Among the 13 outbreaks of known etiology, 5 were caused by Salmonella, 5 by Escherichia coli O157:H7, 2 by Cryptosporidium, and one by Shiga toxin-producing E. coli O111 and Cryptosporidium. Fewer juice-associated outbreaks have been reported since the juice HACCP regulation was implemented. Some juice operations that are exempt from processing requirements or do not comply with the regulation continue to be implicated in outbreaks of illness.

    Full Text Available The Flash Profile is a descriptive analysis method derived from Free-Choice Profile, in which each taster chooses and uses his/her own words to evaluate the product while comparing several attributes. Four passion fruit juices were analyzed, two juices were produced with concentrated juice, one with pulp and one with reconstituted juice; all juices had different levels of sugar, some had gum and dyes. This study aimed to evaluate the physicochemical properties (color, titratable acidity and solid content as well as sensory analysis like Flash profile and affective test. In physicochemical characterization and in Flash Profile, the juice A (pulp had higher solid content and consistence, the juice B (concentrated juice was the least acidic and presented the lowest value of soluble solids and presented strong aroma and flavor of passion-fruit, the juice C (reconstituted juice was pale yellow and showed artificial flavor and the juice D (concentrated juice was the most acidic, consistent with the natural flavor. In the acceptance test, all the juices scored 5-6, indicating that panelists tasters neither liked nor disliked. Flash Profile proved to be an easy and rapid technique showing a good correlation between panelists and the attributes and confirmed the results of physicochemical characterization.

    Full Text Available Introduction: In developing country like India, street foods such as salads and fresh cut fruits are widely consumed. Among all street foods, fruit juices are common beverages, consumed more because of higher consumer preference both in terms of taste and health. Moreover, there is a dearth of Indian studies on contamination of street vended fruit juices. Aim: To determine the pH and specific microorganisms in freshly squeezed street vended fruit juices. Materials and Methods: Four fruit juices i.e., Grapes, Sweet Lime, Pineapple and Sapota were chosen for the study. Juices were collected in summer season in months between April and June 2013. Ten samples of 50 ml each fruit juice was collected in sterile bottles from various street vendors of Dilshuknagar area of Hyderabad city. Transportation of samples to Food Toxicology laboratory, National Institute of Nutrition was done in the ice box and processing was done within 2–4 h. Results: All juices showed bacterial contamination except one sample of grape juice. Pineapple juice samples showed the high bacterial contamination with all samples positive for fecal coliforms and Shigella spp. (100%. Salmonella spp. was detected only in one sample of Sapota juice (10%. Significant difference among fruit juices for prevalence of microorganisms was seen only for Escherichia coli (P = 0.03 with least count in Grape juice (20%. Conclusion: Freshly squeezed street vended fruit juices were contaminated with pathogenic bacteria, which significantly attributed to public health problem.

    2011-01-01

    The effects of fire on wetland vegetation in the mid-Atlantic region of the United States are poorly known, despite the historical use of fire by federal, state, and private landowners in the Chesapeake Bay Region. Prescribed fire is widely used by land managers to promote vegetation that is beneficial to migratory waterfowl, muskrats, and other native wildlife and to reduce competition from less desirable plant species. We compared vegetative response to two fire rotations, annual burns and 3-year burns, and two control sites, Control 1 and Control 2. We tested the effects of fire within six tidal marsh wetlands at Blackwater National Wildlife Refuge and Fishing Bay Wildlife Management Area in Maryland. We examined changes in total live biomass (all species), total stem density, litter, and changes in live biomass and stem density of four dominant wetland plant species (11 variables). Our results suggest that annual prescribed fires will decrease the accumulation of litter, increase the biomass and stem densities of some wetland plants generally considered less desirable for wildlife, and have little or no effect on other wetland plants previously thought to benefit from fire. ?? 2011 US Government.

  12. The marketing of dietary supplements in North America: the emperor is (almost) naked.

    Science.gov (United States)

    Temple, Norman J

    2010-07-01

    Many different dietary supplements are being sold in North America. The quality of the evidence supporting their efficacy covers a wide spectrum: Some are based on solid science (such as vitamin D and fish oil), whereas with most supplements there is little or no supporting evidence. Types of supplements commonly sold include exotic fruit juices (such as goji juice) and single herbs or mixture of herbs. Common claims made in support of particular supplements are that they are rich in antioxidants, induce detoxification, stimulate the immune system, and cause weight loss. Supplements are commonly sold through health food stores and by multilevel marketing. Sales may be promoted using bulk mail ("junk mail"), spam e-mails, and Web sites. A large part of marketing is based on claims that are blatantly dishonest. Whereas supplements for which good supporting evidence exists generally cost around $3-$4 per month, those that are heavily promoted for which there is little supporting evidence cost about $20-$60 per month. The major cause of this problem in the United States is weakness of the law. There is an urgent need for stricter regulation and for giving better advice to the general public.

  13. START (screening tool to alert doctors to the right treatment)--an evidence-based screening tool to detect prescribing omissions in elderly patients.

    LENUS (Irish Health Repository)

    Barry, P J

    2012-02-03

    BACKGROUND: Inappropriate prescribing encompasses acts of commission i.e. giving drugs that are contraindicated or unsuitable, and acts of omission i.e. failure to prescribe drugs when indicated due to ignorance of evidence base or other irrational basis e.g. ageism. There are considerable published data on the prevalence of inappropriate prescribing; however, there are no recent published data on the prevalence of acts of omission. The aim of this study was to calculate the prevalence of acts of prescribing omission in a population of consecutively hospitalised elderly people. METHODS: A screening tool (screening tool to alert doctors to the right treatment acronym, START), devised from evidence-based prescribing indicators and arranged according to physiological systems was prepared and validated for identifying prescribing omissions in older adults. Data on active medical problems and prescribed medicines were collected in 600 consecutive elderly patients admitted from the community with acute illness to a teaching hospital. On identification of an omitted medication, the patient\\'s medical records were studied to look for a valid reason for the prescribing omission. RESULTS: Using the START list, we found one or more prescribing omissions in 57.9% of patients. In order of prevalence, the most common prescribing omissions were: statins in atherosclerotic disease (26%), warfarin in chronic atrial fibrillation (9.5%), anti-platelet therapy in arterial disease (7.3%) and calcium\\/vitamin D supplementation in symptomatic osteoporosis (6%). CONCLUSION: Failure to prescribe appropriate medicines is a highly prevalent problem among older people presenting to hospital with acute illness. A validated screening tool (START) is one method of systematically identifying appropriate omitted medicines in clinical practice.

    Recent studies have suggested that dietary inorganic nitrate (NO₃(-)) supplementation may improve muscle efficiency and endurance exercise tolerance but possible effects during team sport-specific intense intermittent exercise have not been examined. We hypothesized that NO₃(-) supplementation would enhance high-intensity intermittent exercise performance. Fourteen male recreational team-sport players were assigned in a double-blind, randomized, crossover design to consume 490 mL of concentrated, nitrate-rich beetroot juice (BR) and nitrate-depleted placebo juice (PL) over ~30 h preceding the completion of a Yo-Yo intermittent recovery level 1 test (Yo-Yo IR1). Resting plasma nitrite concentration ([NO₂(-)]) was ~400% greater in BR compared to PL. Plasma [NO₂(-)] declined by 20% in PL (P exercise to end-exercise. Performance in the Yo-Yo IR1 was 4.2% greater (P exercise and may be a useful ergogenic aid for team sports players.

    2007-11-01

    There have been recent calls from within both Scotland and England for the wider prescription of heroin to heroin addicts as a way of coping with our burgeoning drug problem and as a route to reducing drug related criminality. But how feasible is heroin prescribing in this context? This paper considers some of the existing research evidence relating to heroin prescribing and looks also at the ethics and practicalities of prescribing heroin to heroin addicts in Scotland. We conclude that whilst the evidence on the benefits of heroin prescribing is far from clear cut there is a case for mounting a Scottish trial of heroin prescribing. Such a trial would need to be tightly controlled and rigorously evaluated. It would need to show that heroin prescribing was associated not only with a comparable level of harm reduction, as methadone prescribing, but that it was also an effective route towards drug users' eventual recovery and drug cessation.

    Nurse Independent and Nurse Supplementary Prescribing has extended the role that nurses in the UK have in the management of care for patients with diabetes. Concerns surround nurses' pharmacological knowledge and provision of continuing professional development to meet the needs of nurse prescribers. To examine the continuing professional development needs of nurses who prescribe medicines to patients with diabetes. A questionnaire survey. The NMC database was used to randomly select and distribute questionnaires to 1992 registered Nurse Independent/Nurse Supplementary Prescribers. One thousand and four hundred questionnaires were returned. Medicines for patients with diabetes were prescribed by 439 respondents. This paper reports on the findings of these 439 nurses. The majority (63%) of nurses worked in general practice. Over 80% reported continuing professional development was available and that they had accessed it to support their prescribing role. Over 40% of nurses had continuing professional development needs in the areas of prescribing policy, pharmacology for diabetes and the management and treatment of diabetes related conditions. Senior nurses reported fewer continuing professional development needs. Access and provision of continuing professional development for nurse prescribers has improved since the initial implementation of nurse prescribing. However, nurse's pharmacological knowledge and the provision of continuing professional development continue to be an area of concern which warrant further investigation. Previous concerns have been identified about the provision of continuing professional development to meet the needs of nurse prescribers. Pharmacological knowledge is still the greatest continuing professional development requirement of nurses who prescribe for patients with diabetes. Education providers may wish to consider developing the content of continuing professional development programmes to meet these needs.

    We report a green and reusable surface-enhanced Raman scattering (SERS) film based on PMMA/Ag NPs/graphene. By using this Raman substrate, the SERS signals of R6G were significantly enhanced reaching a minimum detectable concentration of 5 × 10-8 M, due to having lots of hot spots adhered backside to the exposed graphene. The SERS film can be used for in-situ monitoring of trace thiram in apple juice with a detection limit of 1 × 10-6 M (0.24 ppm), which is below the maximal residue limit (MRL) of 7 ppm in fruit prescribed by the U.S. Environmental Protection Agency (EPA). Furthermore, reusability studies show that the SERS film can be used repeatedly. In addition, the graphene-enhanced SERS technique shows great potential applications for the in-situ detection and identification of pesticide residues in environmental water, fruits and vegetables.

    Social prescribing has emerged as a useful tool for helping patients overcome some of the social and behavioural determinants of poor health. There has been little research on the impact of social prescribing on use of primary healthcare resources. This study sought to determine whether social prescribing activities influenced patient-general practitioner (GP) contacts and polypharmacy. Quality-improvement design with social prescribing activity interventions from an urban general practice in Northern Ireland. Patients over 65 years of age with a chronic condition who attended their GP frequently or had multiple medications were offered a social prescribing activity. Participants' contacts with GP and the new repeat prescriptions before and during the social prescribing activity were measured. The total number of repeat prescriptions per patient was compared at the time of referral and 6-12 months later. Indications for referral, primary diagnoses and reasons for declining participation in a social prescribing activity after referral were prospectively recorded. Sixty-eight patients agreed to participate but only 28 (41%) engaged in a prescribed social activity. There was no statistically significant difference in GP contacts (visits to GP, home visits or telephone calls) or number of new repeat prescriptions between referral and completion of 12 weeks of social prescribing activity. Similarly there was no statistically significant difference in the total number of repeat prescriptions between referral and 6-12 months after social prescribing activity in either intention to treat or per protocol analyses. Social prescribing participants had similar demographic factors. Mental health issues (anxiety and/or depression) were more common among participants than those who were referred but declined participation in a social prescribing activity (P = 0.022). While social prescribing may help patients' self-esteem and well-being, it may not decrease GP workload. Further

    To describe facilitators and barriers in relation to the growth of nurse prescribing competence from the perspective of the nurses studying in a prescribing programme. The number of nurses enrolled in a nurse prescribing programme is rapidly increasing in Finland. However, few studies on nurse prescribing education are available and therefore research is needed, particularly from the point of view of nurses studying in the programme. The descriptive, qualitative study used the text of student online learning diaries as data during a 14-month prescribing programme. The sample consisted of 31 nurses, public health nurses or midwives enrolled in a prescribing programme at a university of applied sciences. The data were analysed using the inductive analysis method. The growth of nurses' prescribing competence was facilitated by learning clinical examination of the patient, networking with peers, receiving support from the workplace and supervisors, doctors' positive attitude towards nurse prescribing and being able to apply competencies directly to nursing practice. The barriers to the growth of nurses' prescribing competence were unclear job description, incomplete care plans and concerns about how consultation with doctors will be organised and realised. The results show that, for the purpose of developing the new role and position of nurse prescribers, educators and nursing managers must invest more in staff awareness of nurse prescribing education and also offer more support to nurse prescribers in their workplaces. The results of this study can be used especially in countries where nurse prescribing education is only in the process of being planned or has just been started. Heads of nursing and educators in prescribing education will benefit from the results when creating expanded job descriptions for nurses and supporting networking between students during the period of training. © 2016 John Wiley & Sons Ltd.

    The effects of a flavonoid-rich fresh fruit and vegetable juice (JUICE) on chronic resting and postexercise inflammation, oxidative stress, immune function, and metabolic profiles (metabolomics analysis, gas-chromatography mass-spectrometry platform) in elite sprint and middle-distance swimmers were studied. In a randomized, crossover design with a 3-wk washout period, swimmers (n = 9) completed 10-d training with or without 16 fl oz of JUICE (230 mg flavonoids) ingested pre- and postworkout. Blood samples were taken presupplementation, post-10-d supplementation, and immediately postexercise, with data analyzed using a 2 × 3 repeated-measures ANOVA. Prestudy blood samples were also acquired from nonathletic controls (n = 7, age- and weight-matched) and revealed higher levels of oxidative stress in the swimmers, no differences in inflammation or immune function, and a distinct separation in global metabolic scores (R2Y [cum] = .971). Swim workouts consisted of high-intensity intervals (1:1, 1:2 swim-to-rest ratio) and induced little inflammation, oxidative stress, or immune changes. A distinct separation in global metabolic scores was found pre- to postexercise (R2Y [cum] = .976), with shifts detected in a small number of metabolites related to substrate utilization. No effect of 10-d JUICE was found on chronic resting levels or postexercise inflammation, oxidative stress, immune function, and shifts in metabolites. In conclusion, sprint and middle-distance swimmers had a slight chronic elevation in oxidative stress compared with nonathletic controls, experienced a low magnitude of postworkout perturbations in the biomarkers included in this study, and received no apparent benefit other than added nutrient intake from ingesting JUICE pre- and postworkout for 10 days.

    The aim of this study is to investigate the simultaneous effect of pomegranate juice on components of the metabolic syndrome, including high sensitive C-reactive protein (hs-CRP) as an inflammatory index and glycemic and lipid profile indices in patients with metabolic syndrome. In a double- blind 2*2 crossover study, 30 individuals suffering from metabolic syndrome received a daily dose of 500 mL pomegranate juice for a period of one week. After one week of wash out period, they received a placebo for one week. Lipid profile, blood glucose control indices including fasting blood glucose, fasting insulin, homeostatic model assessment of insulin resistance (HOMA-IR), systolic and diastolic blood pressure, and hs-CRP were measured at the beginning and end of the study. To analyze the data, a repeated measure analysis of variance and a t-test were performed. The results indicated that in comparison to the placebo, pomegranate juice was more effective in reducing the systolic and diastolic blood pressure (p = 0.00) and hs-CRP (p = 0.018). The level of triglyceride (p = 0.030) and very low-density lipoproteins cholesterol (VLDL-C) (p = 0.014) were increased after the consumption of pomegranate juice, as opposed to the baseline condition. The rest of lipid profile, fasting blood glucose (FBS), insulin, and HOMA-IR of the participants did not show any significant difference. Natural pomegranate juice supplementation lowered the level of systolic and diastolic blood pressure in patients with metabolic syndrome as well as their blood hs-CRP. However, it also increased their triglyceride and VLDL-C.

    Phenolic compounds of fruit juices are responsible for haze and sediment formation as well as for color, bitterness and astringency. The influence of ultrafiltration (UF) and laccase-UF combination was investigated on phenolic contents of pomegranate juices and on filtration output. Laccase-treated and then ultrafiltered pomegranate juices have shown a rapid increase in their color, when compared to only ultrafiltered (control) samples. Kinetic parameters of laccase were also determined. During the oxidation period, the changes occurring in pomegranate juices were estimated from phenolic contents, color and anthocyanin measurements. Results have shown that laccase oxidation produced a significant decrease in phenolic content of pomegranate juices while juice color the increased. However, in recent literatures, the possibility to remove polyphenols in apple juices was reported. We decided in this study that laccase treatment can not be applied due to the loss of natural red color and unwanted dark brownish color formation in pomegranate juice.

    We studied the antioxidant effects of fresh juice and peel extract of Citrus aurantifolia (Christm). Low density lipoprotein (LDL) was separated from one hypercholesterolemic human serum by modified Bronzert and Brewer procedure. Oxidation of LDL was measured at 234 nm against 0, 5, 10, 20, 25, 30 and 40 μl of fresh lime juice and 0, 5, 10, 15 and 20 μl of peel polyphenolic extract solution in DMSO. 5 μl of lime juice didn't change LDL oxidation. 10 μl of juice inhibited LDL oxidation, and with increasing the juice concentration, LDL was oxidized faster. The higher concentrations of peel extract prevented LDL oxidation better than the lower ones. Both juice and peel demonstrated antioxidant properties, but the excessive consumption of lime juice seems not to be beneficial. Regarding the intensity and type of flavonoids, lime juice and peel may show different effects.

    To establish a method for comparing the differences between fresh and dried ginger juice. The RP-HPLC fingerprint method was performed on an Alltech C18 column (4.6 mm x 250 mm, 5 microm) with mobile phase in gradient elution composed of A-acetonitrie and B-water at a flow rate: 0.8 mL x min(-1). The detecting wavelength was 280 nm, and the column temperature 25 degrees C. There was no significant difference among the same breed ginger juice of different batches. But there was significant difference between crushed ginger juice and the boiled juice. Trytophan, 6-gingerol were common constituents of the three kinds of ginger juice, the fresh ginger and the dry ginger. Besides, 6-shogaol emerged in the boiled juice. The RP-HPLC fingerprints spectrum can be used to distinguish different ginger juices. And the crushed juice of fresh ginger have the same chemical consititents with the fresh ginger.

    The aim of this work was to find sensory suitable combinations of not commonly used vegetables, that is, cabbage, celeriac and parsnip, into mixed fruit-vegetable juices, two-species vegetable juices and vegetable juices with whey. These juices might have the potential to offer consumers new, interesting, tasty and nutritional products. Another interesting variation could be preparation of vegetable juices in combination with sweet whey. Nutritional and sensory evaluations were carried out using juices prepared in the laboratory. The total phenolic content, in addition to ascorbic acid and antioxidant activity, was determined. The developed juices with high nutritional value should increase very low fruit and vegetable consumption in the Czech population. The prepared juices were high pressure pasteurized (410 MPa). This technique retains the desired levels of important nutritional substances, while being destructive to live microbial cell structure. The germination of spores is suppressed by low pH value.

    The biologically active constituents of pennywort juice were analyzed by HPLC. The juice extract contained the bioactive glycosides, including asiaticoside and madecassoside. Antioxidant properties of juices were determined in terms of ferric-reducing antioxidant power assay, total polyphenol, β-carotene and ascorbic acid contents. After processing, asiaticoside, madecassoside and β-carotene in the extracted juice were relatively stable with no significant losses occurring. Pressurization could significantly retain ascorbic acid, polyphenols and antioxidant capacity than those pasteurization or sterilization. For storage assessment, asiaticoside in the processed juices was relatively stable during 4 months storage. Losses of ascorbic acid in the pressurized juice during storage were greater than in pasteurized and sterilized juice. However, the total amount of ascorbic acid retained in pressurized juice was still higher than those thermal-treated products.

    Full Text Available The purpose of the present study was to evaluate the erosive potential of different types (concentrated and powdered and commercial brands of industrialised grape juices. The pH of all five fruit drinks was measured at two time points: immediately after preparation and 24 hours later. Sixty specimens of bovine enamel were randomly allocated and immersed in different types of grape juice (n = 10 for 10 minutes four times a day for fifteen days. The enamel alteration was analysed using surface Knoop microhardness (KHN and surface roughness (Ra tests at baseline and on the 5th, 10th and 15th days of the experiment. Two way ANOVA, Tukey's post hoc and Pearson's correlation tests were used for statistical analysis (α = 5%. The grape juices presented pH values ranging from 2.9 to 3.5. All of the tested juices promoted significant enamel mineral loss (p < 0.05 on the first evaluation (5th day of immersion and produced a significant increase in the mean roughness from the 10th day on when compared to the control group (p < 0.05. By the 15th day, all of the beverages had produced surface roughnesses that were significantly higher than that of the control group. The results suggest that all grape juices, regardless of their commercial presentation, present erosive potential.

    One hundred and twenty children with acute uncomplicated malaria who were managed at the children's outpatient department of the Wesley Guild Hospital, Ilesa (a unit of Obafemi Awolowo University Teaching Hospitals' Complex, Ile-Ife, Osun state, Nigeria) were recruited into the study to determine the effects of lime juice on malaria parasite clearance. These children were randomized into treatment with World Health Organization recommended antimalarials (artemisinin combination therapy, ACT) either alone or with lime juice. Nine of them were lost to follow-up, four were in the group that were managed with ACT and lime, and five in the group that were managed on ACT alone. The average (SD) time to achieve >75% reduction in parasite load was significantly lower in patients on ACT and lime; 30.5 ± 2.4 h against 38.6 ± 3.3 h for those on ACT alone (p lime juice achieved complete parasite clearance by 72 h of therapy (p = 0.007), ten (18.2%) patients without lime had early treatment failure (p = 0.003). There were no side effects with the use of lime juice. It may therefore be inferred, from this preliminary work, that lime juice when used with the appropriate antimalarial may enhance malaria parasite clearance especially in those with uncomplicated malaria.

    Full Text Available Fruits rich in polyphenols, such as pomegranates, have been shown to have health benefits relating to their antioxidant and anti-inflammatory properties. Using data obtained from PubMed and Scopus, this article provides a brief overview of the therapeutic effects of pomegranate on chronic inflammatory diseases (CID such as inflammatory bowel disease (IBD, rheumatoid arthritis (RA, metabolic and cardiovascular disorders, and other inflammatory-associated conditions, with an emphasis on fruit-derived juices. Most studies regarding the effects of pomegranate juice have focused on its ability to treat prostate cancer, diabetes, and atherosclerosis. However, pomegranate juice has shown therapeutic potential for many other illnesses. For instance, a small number of human clinical trials have highlighted the positive effects of pomegranate juice and extract consumption on cardiovascular health. The beneficial effects of pomegranate components have also been observed in animal models for respiratory diseases, RA, neurodegenerative disease, and hyperlipidaemia. Furthermore, there exists strong evidence from rodent models suggesting that pomegranate juice can be used to effectively treat IBD, and as an anti-inflammatory agent to treat CID. The effects of pomegranate intake should be further investigated by conducting larger and more well-defined human trials.

    In vitro digestion models have been developed to estimate carotenoid bioavailability but most do not consider that their diffusion from fruit matrix to the lipid phase of the bolus could be a limiting step. Therefore we designed a model in which tomato juice is mixed with oil or oil/water emulsions, and the carotenoids diffusing to oil are measured by spectrometry. Temperature, pH and tomato juice/peanut oil ratio were evaluated for their influence on carotenoid diffusion. When oil/tomato ratio was between 0.11 and 1, extraction of lycopene was limited by the saturation of the oil phase. With a large excess of oil, diffusion was also limited, as only 31 ± 1% of lycopene could be extracted from the juice. Diffusion did not vary significantly with pH but doubled when temperature rose from 10°C to 37°C. When the juice was mixed in an emulsion stabilised with bovine serum albumin or phospholipids the maximum extraction decreased to 14.5 ± 0.2% and 18.5 ± 1.5% respectively, indicating that in addition to the saturation of the oil phase at low oil/tomato ratio and in addition to intrinsic properties of the tomato juice in non-saturating conditions, lycopene diffusion was limited by the structure of the interface in emulsions.

    Cranberry is recognized for its many benefits on human health; however, its high acidity may be a limiting factor for its consumption. This study aimed to investigate the deacidification of cranberry juice using a two simultaneous step electrodialysis with bipolar membranes (EDBM) process. In step 1 (deacidification), during the 6 h treatment, the pH of the juice increased from 2.47 to 2.71 and a deacidification rate of 22.84% was obtained, whereas in step 2 (pH lowering) the pH of juice 2 was almost stable. Citric, quinic, and malic acid were extracted with a maximum of 25% and were mainly transferred to the KCl 2 fraction. A significant loss of anthocyanins in juice 2 (step 2) was observed, due to their oxidation by oxygen incorporated by the centrifugal pump. This also affected its coloration. The first step of the EDBM process was successful for cranberry juice deacidification and could be improved by increasing the number of membranes stacked.

    Antidepressant prescribing continues to increase, with 5-16% of adults receiving antidepressants annually. Total prescribing growth is due in part to increased long-term use, greater selective serotonin re-uptake inhibitor (SSRI) use and the use of higher SSRI doses. Evidence does not support routine use of higher SSRI doses for depression treatment, and factors influencing the use of such doses are not well known. The aim of this study was to explore factors influencing GPs' use of antidepressants and their doses to treat depression. Semi-structured interviews with a purposive sample of 28 practising GPs; sampled by antidepressant prescribing volume, practice size and deprivation level. A topic guide drawing on past literature was used with enough flexibility to allow additional themes to emerge. Interviews were audio-recorded and transcribed verbatim. Framework analysis was employed. Constant comparison and disconfirmation were carried out across transcripts, with data collection being interspersed with analysis by three researchers. The thematic framework was then systematically applied to the data and conceptualised into an overarching explanatory model. Depression treatment involved ethical and professional imperatives of 'doing the right thing' for individuals by striving to achieve the 'right care fit'. This involved medicalised and non-medicalised patient-centred approaches. Factors influencing antidepressant prescribing and doses varied over time from first presentation, to antidepressant initiation and longer-term treatment. When faced with distressed patients showing symptoms of moderate to severe depression GPs were confident prescribing SSRIs which they considered as safe and effective medicines, and ethically and professionally appropriate. Many GPs were unaware that higher doses lacked greater efficacy and onset of action occurred within 1-2 weeks, preferring to wait 8-12 weeks before increasing or switching. Ongoing pressures to maintain

    Surveys of mitochondrial disease physicians conducted through the Mitochondrial Medicine Society have shown that virtually all providers recommend a variety of dietary supplements as treatments to their patients in an effort to enhance energy production and reduce oxidative stress. In this survey, we asked patients and their parents about their experiences taking these dietary supplements for mitochondrial disease. The survey was disseminated through the North American Mitochondrial Disease Consortium (NAMDC) and the Rare Disease Clinical Research Network (RDCRN) registries and gathered 162 responses. The study ascertained each patient's mitochondrial disease diagnosis, dietary supplements used, adjunct therapy, and effects of the supplements on symptoms and health. Regardless of the specific underlying mitochondrial disease, the majority of the survey respondents stated they are or have been on dietary supplements. Most patients take more than four supplements primarily coenzyme Q10, l-carnitine, and riboflavin. The majority of patients taking supplements reported health benefits from the supplements. The onset of perceived benefits was between 2weeks to 3months of initiating intake. Supplements seem to be safe, with only 28% of patients experiencing mild side-effects and only 5.6% discontinuing their intake due to intolerance. Only 9% of patients had insurance coverage for their supplements and when paying out of pocket, 95% of them spend up to $500/month. Despite the use of concomitant therapies (prescribed medications, physical therapy, diet changes and other), 45.5% of patients think that dietary supplements are the only intervention improving their symptoms. Some limitations of this study include the retrospective collection of data probably associated with substantial recall bias, lack of longitudinal follow up to document pre- and post-supplement clinical status and second hand reports by parents for children which may reflect parents' subjective

    Polyphenols in noni juice (NJ) are mainly composed of phenolic acids, mainly gentisic, p-hydroxybenoic, and chlorogenic acids. To investigate the beneficial effects of NJ on the liver, hamsters were fed with two diets, normal-fat and high-fat diets. Furthermore, high-fat dietary hamsters were received distilled water, and 3, 6, and 9 mL NJ/kg BW, respectively. After a 6-week feeding period, the increased (p<0.05) sizes of liver and visceral fat in high-fat dietary hamsters compared to the control hamsters were ameliorated (p<0.05) by NJ supplementation. NJ also decreased (p<0.05) serum/liver lipids but enhanced (p<0.05) daily faecal lipid/bile acid outputs in the high-fat dietary hamsters. High-fat dietary hamsters supplemented with NJ had higher (p<0.05) liver antioxidant capacities but lowered (p<0.05) liver iNOS, COX-2, TNF-α, and IL-1β expressions, gelatinolytic levels of MMP9, and serum ALT values compared to those without NJ. Hence, NJ protects liver against a high-fat dietary habit via regulations of antioxidative and anti-inflammatory responses.

  2. Comparative study of pulsed electric field and thermal processing of apple juice with particular consideration of juice quality and enzyme deactivation.

    As an alternative to thermal pasteurization, pulsed electric fields (PEF) were applied to apple juices on laboratory and pilot plant scale, investigating the effects on juice quality. PEF application still falls under the EU Novel Food Regulation. Consequently, extensive investigation of quality parameters is a prerequisite to prove substantial equivalence of juices resulting from the novel process and conventional production, respectively. Juice composition was not affected by PEF treatment. However, browning of the juices provided evidence of residual enzyme activities. On laboratory scale, complete deactivation of peroxidase (POD) and polyphenoloxidase (PPO) was achieved when PEF treatment and preheating of the juices to 60 degrees C were combined. Under these conditions, a synergistic effect of heat and PEF was observed. On pilot plant scale, maximum PPO deactivation of 48% was achieved when the juices were preheated to 40 degrees C and PEF-treated at 30 kV/cm (100 kJ/kg). Thus, minimally processed juices resulted from PEF processing, when applied without additional conventional thermal preservation. Since this product type was characterized by residual native enzyme activities and nondetectable levels of 5-hydroxymethylfurfural, also when preheating up to 40 degrees C was included, it ranged between fresh and pasteurized juices regarding consumers' expectation of freshness and shelf life. Consistent with comparable iron contents among all juice samples, no electrode corrosion was observed under the PEF conditions applied.

  3. Lorentzian Einstein metrics with prescribed conformal infinity

    Enciso, Alberto

    2014-01-01

    We prove that there are asymptotically anti-de Sitter Einstein metrics with prescribed conformal infinity. More precisely we show that, given any suitably small perturbation $\\hat g$ of the conformal metric of the $(n+1)$-dimensional anti-de Sitter space at timelike infinity, which is given by the canonical Lorentzian metric on the $n$-dimensional cylinder, there is a Lorentzian Einstein metric on $(-T,T)\\times \\mathbb{B}^n$ whose conformal geometry is given by $\\hat g$. This is a Lorentzian counterpart of the Graham-Lee theorem in Riemannian geometry and is motivated by the holographic prescription problem in the context of the AdS/CFT correspondence in string theory.

  8. Fruit juice, organic anion transporting polypeptides, and drug interactions in psychiatry.

    Andrade, Chittaranjan

    2014-11-01

    Organic anion transporting polypeptides (OATPs) are a group of membrane transport proteins that facilitate the influx of endogenous and exogenous substances across biological membranes. OATPs are found in enterocytes and hepatocytes and in brain, kidney, and other tissues. In enterocytes, OATPs facilitate the gastrointestinal absorption of certain orally administered drugs. Fruit juices such as grapefruit juice, orange juice, and apple juice contain substances that are OATP inhibitors. These fruit juices diminish the gastrointestinal absorption of certain antiallergen, antibiotic, antihypertensive, and β-blocker drugs. While there is no evidence, so far, that OATP inhibition affects the absorption of psychotropic medications, there is no room for complacency because the field is still nascent and because the necessary studies have not been conducted. Patients should therefore err on the side of caution, taking their medications at least 4 hours distant from fruit juice intake. Doing so is especially desirable with grapefruit juice, orange juice, and apple juice; with commercial fruit juices in which OATP-inhibiting substances are likely to be present in higher concentrations; with calcium-fortified fruit juices; and with medications such as atenolol and fexofenadine, the absorption of which is substantially diminished by concurrent fruit juice intake.

    This research analyzed the major chemical components and multiple antioxidant activities present in the fresh juice of eight vegetables, and studied their influence on starch induced postprandial glycemia in rats. A SDS-PAGE based protein fingerprint of each vegetable juice was also prepared. The yields of juice, chemical components like total proteins, total polyphenols, total flavonoids, total anthocyanins and free radicals like the ABTS˙(+) cation, DPPH, H(2)O(2), scavenging activities and reducing properties for NBT and FeCl(3) showed wide variations. Vegetable juice from brinjal ranked first in displaying total antioxidant capacity. Pretreatment of rats with vegetable juices moderated starch induced postprandial glycemia. The fresh juice from the vegetables ridge gourd, bottle gourd, ash gourd and chayote significantly mitigated postprandial hyperglycemic excursion. Total polyphenol concentrations present in vegetable juices positively influenced ABTS˙(+) scavenging activity and total antioxidant capacity. However, NBT reducing activity of juices was positively affected by total protein concentration. Contrarily, however, high polyphenol content in vegetable juice was observed to adversely affect the postprandial antihyperglycemic activity of vegetable juices. This is the first report exploring antihyperglycemic activity in these vegetable juices and highlights the possible adverse influence of high polyphenol content on the antihyperglycemic activity of the vegetable juices.

    Orange juice is a well-accepted fruit juice, and its consumption increases steadily. Many studies have been conducted to understand the sensory characteristics of orange juice throughout its varying processing steps. Sensory language and consumer likings of food can be influenced by culture. The objective of this study is to evaluate the sensory characteristics of commercially available orange juices in Korea and identify drivers of liking for orange juices in Korea. A quantitative descriptive analysis was conducted using a trained panel (n = 10) to evaluate 7 orange juice samples in triplicates, followed by consumer acceptance tests (n = 103). Univariate and multivariate statistical analyses were conducted for data analysis. The sensory characteristics of commercially available orange juice were documented and grouped: group 1 samples were characterized by high in natural citrus flavors such as orange peel, orange flesh, citrus fruit, and grape fruit, whereas group 2 samples were characterized by processed orange-like flavors such as over-ripe, cooked-orange, and yogurt. Regardless of orange flavor types, a high intensity of orange flavor in orange juice was identified as a driver of liking for orange juices in Korea. Three distinct clusters were segmented by varying sensory attributes that were evaluated by likes and dislikes. Overall, many similarities were noticed between Korean market segment and global orange juice market. By knowing the drivers of liking and understanding the distinct consumer clusters present in the Korean orange juice market, the orange juice industry could improve the strategic marketing of its products in Korea.

    2016-01-01

    Economically motivated adulteration (EMA) of lemon juice was detected by LC-MS and principal component analysis (PCA). Twenty-two batches of freshly squeezed lemon juice were adulterated by adding an aqueous solution containing 5% citric acid and 6% sucrose to pure lemon juice to obtain 30%, 60% and 100% lemon juice samples. Their total titratable acidities, °Brix and pH values were measured, and then all the lemon juice samples were subject to LC-MS analysis. Concentrations of hesperidin and eriocitrin, major phenolic components of lemon juice, were quantified. The PCA score plots for LC-MS datasets were used to preview the classification of pure and adulterated lemon juice samples. Results showed a large inherent variability in the chemical properties among 22 batches of 100% lemon juice samples. Measurement or quantitation of one or several chemical properties (targeted detection) was not effective in detecting lemon juice adulteration. However, by using the LC-MS datasets, including both chromatographic and mass spectrometric information, 100% lemon juice samples were successfully differentiated from adulterated samples containing 30% lemon juice in the PCA score plot. LC-MS coupled with chemometric analysis can be a complement to existing methods for detecting juice adulteration.

    The mechanism of action of the antidiabetic capacity of Momordica charantia is still under investigation. Here, we assessed phytochemical compositions, antioxidant activity, and effects of total and filtered fruit and leafy stem juices of Momordica charantia on human T cell proliferation and differentiation through quantification of Th1/Th2 cytokines. In the absence of stimulation, total fruit and leafy stem juices induced significant T cell proliferation. Under PHA stimulation, both juices potentiated plant-induced T cell proliferation. However, the filtered fruit and leafy stem juices significantly inhibited PHA-stimulated T cell proliferation, while neither juice influenced T cell proliferation. Moreover, total and filtered fruit juice increased IL-4 secretion, while total and filtered leafy stem juice enhanced IFN-γ production. Phytochemical screening revealed the presence of tannins, flavonoids, anthocyans, steroids, and triterpenoids in both juices. Alkaloids, quinone derivatives, cardenolides, and cyanogenic derivatives were undetectable. The saponins present in total juices were undetectable after filtration. Moreover, both juices had appreciable antioxidant capacity. Our study supports the type 1 antidiabetic effect of filtered fruit juice of M. charantia which may be related to its immunosuppressive and T-helper 2 cell inducing capacities. Due to their immune-stimulatory activities and their ability to increase T-helper 1 cell cytokines, total fruit and leafy stem juices may serve in the treatment of immunodeficiency and certain infections.

    The Healthy Hunger-Free Kids Act of 2010 presents an opportunity to change the nutritional quality of foods served in low-income childcare centers, including Head Start centers. Excessive fruit juice consumption is associated with increased risk for obesity. Moreover, there is recent scientific evidence that sucrose consumption without the corresponding fiber, as is commonly present in fruit juice, is associated with the metabolic syndrome, liver injury, and obesity. Given the increasing risk of obesity among preschool children, we recommend that the US Department of Agriculture's Child and Adult Food Care Program, which manages the meal patterns in childcare centers such as Head Start, promote the elimination of fruit juice in favor of whole fruit for children.

    Full Text Available Abstract Background The use of herbal medicines (medicinal plants or phytotherapy has recently gained popularity in Europe and the United States. Nevertheless the exact mechanism of the preventive effects of these products is still far to be clearly established, being its knowledge necessary to successfully apply these therapies to avoid stone formation. Methods The effect of oral lemon juice administration on calcium oxalate urolithiasis was studied in male Wistar rats. Rats were rendered nephrolithic by providing drinking water containing 0.75% ethylene glycol [v/v] (EG and 2% ammonium chloride [w/v] (AC for 10 days. In addition to EG/AC treatment, three groups of rats were also gavage-administered solutions containing 100%, 75% or 50% lemon juice [v/v] (6 μl solution/g body weight. Positive control rats were treated with EG/AC but not lemon juice. Negative control rats were provided with normal drinking water, and were administered normal water by gavage. Each group contained 6 rats. After 10 days, serum samples were collected for analysis, the left kidney was removed and assessed for calcium levels using flame spectroscopy, and the right kidney was sectioned for histopathological analysis using light microscopy. Results Analysis showed that the rats treated with EG/AC alone had higher amounts of calcium in the kidneys compared to negative control rats. This EG/AC-induced increase in kidney calcium levels was inhibited by the administration of lemon juice. Histology showed that rats treated with EG/AC alone had large deposits of calcium oxalate crystals in all parts of the kidney, and that such deposits were not present in rats also treated with either 100% or 75% lemon juice. Conclusion These data suggest that lemon juice has a protective activity against urolithiasis.

    Full Text Available Objective: The aims of this study were to identify potentially inappropriate prescribing using the Beers and STOPP criteria. The START criteria were applied to detect prescription omission in the geriatric population. We compared the utility of these criteria in institutionalised older people.Methods: Descriptive study reviewing the medication and clinical records of 81 residents (aged 65 years and more by pharmacists in a nursing home in the Lleida region (Spain.Results: The mean patients’ age was 84 (SD=8 years, with an average of 5 drugs per resident (total prescriptions: 416 medicines. The Beers criteria identified potentially inappropriate medication use in 25% of patients and 48% of patients used at least 1 inappropriate medication according to STOPP criteria. The most frequent potentially inappropriate medications for both criteria were long-acting benzodiazepines and NSAIDs. START detected 58 potential prescribing omissions in 44% of patients. Calcium-vitamin D supplementation in osteoporosis was the most frequent rule (15%, but omissions corresponding to the cardiovascular system implied 23% of patients.Conclusion: The STOPP-START criteria reveal that potentially inappropriate prescribing (PIP is a highly prevalent problem among Spanish nursing home residents, and a statistically significant positive correlation was found between the number of medicines prescribed and the number of PIP detected in this study. The STOPP criteria detect a larger number of PI medications in this geriatric population than the Beers criteria. The prescribing omissions detected by the START criteria are relevant and require intervention. Pharmacists’ review of medications may help identify potentially inappropriate prescribing and, through an interdisciplinary approach, working with physicians may improve prescribing practices among geriatric residents of nursing homes.

    The aim of the study was to describe the prescribing of drugs to pregnant women during the third trimester of pregnancy. The retrospective analysis is interested by pregnant women from August 2009 to April 2011, living in Franche-Comté. The used data are recorded in the database of the French Health Insurance Service. Drugs prescribing were analyzed and classified according to three categories: drugs that are contraindicated, not recommended drugs and drugs that are used. This classification is based on two databases: the Summaries of Product Characteristics of Vidal 2010 and data from the National Security Agency of Medicines. The potential exposure of patients was pointed out. On 15,027 patients, 80% had a prescription. Six percent of prescriptions containing drugs not recommended and 1% drugs that contraindicated. Therapeutic classes identified are analgesics, anti-infective drugs and medicines supplementing with vitamins and minerals. Contraindicated drugs (10%) are NSAIDs, rubella vaccine, cyclins and ACE inhibitors and ARBs. Approximately 2.7% of women were potentially exposed to these drugs. Despite the recommendations of the ANSM, some drugs that are contraindicated are prescribed for pregnant women in their third trimester of pregnancy. In the absence of studies, the decision must be made on a case by case basis by assessing the risk-benefit ratio. Particular care is to bring about the drugs taken in self-medication. Information and advice are key steps to avoid incidents. Copyright © 2015 Elsevier Masson SAS. All rights reserved.

    2017-08-01

    Although prescribing of medication in hospitals is rarely an error-free process, prescribers receive little feedback on their mistakes and ways to change future practices. Audit and feedback interventions may be an effective approach to modifying the clinical practice of health professionals, but these may pose logistical challenges when used in hospitals. Moreover, such interventions are often labor intensive. Consequently, there is a need to develop effective and innovative interventions to overcome these challenges and to improve the delivery of feedback on prescribing. Implementation intentions, which have been shown to be effective in changing behavior, link critical situations with an appropriate response; however, these have rarely been used in the context of improving prescribing practices. Semistructured qualitative interviews were conducted to evaluate the acceptability and feasibility of providing feedback on prescribing errors via MyPrescribe, a mobile-compatible website informed by implementation intentions. Data relating to 200 prescribing errors made by 52 junior doctors were collected by 11 hospital pharmacists. These errors were populated into MyPrescribe, where prescribers were able to construct their own personalized action plans. Qualitative interviews with a subsample of 15 junior doctors were used to explore issues regarding feasibility and acceptability of MyPrescribe and their experiences of using implementation intentions to construct prescribing action plans. Framework analysis was used to identify prominent themes, with findings mapped to the behavioral components of the COM-B model (capability, opportunity, motivation, and behavior) to inform the development of future interventions. MyPrescribe was perceived to be effective in providing opportunities for critical reflection on prescribing errors and to complement existing training (such as junior doctors' e-portfolio). The participants were able to provide examples of how they would use

    Full Text Available The production of guava juice fortified with soluble dietary fiber as pectin extracted from guava cake (peel, pulp, seeds was conducted. The waste guava cake from juice processing plant was used for pectin extraction using sodium hexametaphosphate method followed by pectin precipitation using acidified ethanol method. A yield of 30.50±0.34% crude pectin was achieved. Crude pectin also contained 4.71±0.18% moisture, 0.34±0.21% protein, 0.68±0.00% ash, 20.70±0.16 g (%dwb soluble dietary fibers. pH of crude pectin was 3.06±0.02. The L* a*and b* values were 81.17±0.21, 4.76±0.04 and 15.43±0.07, respectively. Water holding capacity and bulk density were 0.90±0.01 g.water/g.solid and 0.96±0.05 g/ml, respectively. This study found that the optimum conditions for guava juice extraction using pectinase at 45oC were 0.10 % v/v pectinase concentration and 21 2 h incubation time. Under these optimum conditions, production of guava juice with different ratios of total soluble solids (oBrix to acid as citric acid content (% including, 24.0, 28.0, 32.0, 35.0 and 40.0 oBrix-acid ratio, and product sensory evaluation were also conducted. By the consideration from the greatest perceived scores of all sensory evaluation attributes including color, turbidity, odor, flavor and overall acceptability, the oBrix-acid ratio of 40.0 was selected for guava juice processing. The clarified guava juice was then fortified with pectin powder extracted from previous experiments using various pectin concentrations: 0, 0.25, 0.50 and 0.75% (w/w. It was found that the perceived scores of the overall acceptability attribute decreased (p<0.05 with increasing of pectin concentration. The greatest perceived score of the mouthfeel attribute was observed from the use of 0.25% pectin. Therefore, the optimum concentration of 0.25% soluble dietary fiber as pectin for guava juice fortification is selected for further guava juice processing.

    The present study was carried out to evaluate the heavy metal content of 21 Romanian single strength fruit (plum, apple, sour cherry) juices. The samples were collected from five Romanian areas namely: Alba, Maramures, Cluj, Salaj and Moldova. The results indicated macro (Na, Mg, Ca, P) and micro (Fe, Zn, Ni, Cr, Cd, Pb, etc) elements in the selected samples. The determination was performed by ICP-MS. Our results for fruit juice were compared with allowable limits for drinking water in the United Kingdom (NS30).

    A comprehensive profile of flavonoids in bergamot juice was obtained by a single DAD-ESI-LC-MS-MS course. Eight flavonoids were found for the first time, five of these are C-glucosides (lucenin-2, stellarin-2, isovitexin, scoparin, and orientin 4'-methyl ether), and three are O-glycosides (rhoifolin 4'-O-glucoside, chrysoeriol 7-O-neohesperidoside-4'-O-glucoside, and chrysoeriol 7-O-neohesperidoside). A method is proposed to differentiate chrysoeriol and diosmetin derivatives, which are often indistinguishable by LC-MS-MS. In-depth knowledge of the flavonoid content is the starting point for bergamot juice exploitation in food industry applications.

    Cashew apple and guava residues from fruit juice industry were prepared as dehydrated fruit powders and used at different levels of wheat flour substitution for cookies formulations. The effects of guava and cashew apple fruit powders supplementation on physicochemical and sensorial characteristics of the cookies were evaluated. The pH, fibre and protein content were significantly affected. Biscuits with 15 g and 20 g/100g cashew apple and guava fruit powders showed the highest scores for sensorial attributes, respectively. The supplementation seems to be suited for wheat flour substitution and it is possible to obtain cookies with value-added food ingredient within the standards.

    and after pregnancy were identified in each of the databases. AED prescribing patterns were analysed, and the choice of AEDs and co-prescribing of folic acid were evaluated. Results In total, 978 957 women with 1 248 713 deliveries were identified. In all regions, AED prescribing declined during pregnancy...... co-prescribed with high-dose folic acid: ranging from 1.0% (CI950.3–1.8%) in Emilia Romagna to 33.5% (CI9528.7–38.4%) in Wales. Conclusion The country's differences in prescribing patterns may suggest different use, knowledge or interpretation of the scientific evidence base. The low co......-prescribing of folic acid indicates that more needs to be done to better inform clinicians and women of childbearing age taking AEDs about the need to offer and receive complete preconception care....

    The pain medication OxyContin (hereafter referred to as oxycodone extended release) has been the subject of sustained, and largely negative, media attention in recent years. We sought to determine whether media coverage of oxycodone extended release in North American newspapers has led to changes in prescribing of the drug in Nova Scotia, Canada. An interrupted time-series design examined the effect of media attention on physicians' monthly prescribing of opioids. The outcome measures were, for each physician, the monthly proportions of all opioids prescribed and the proportion of strong opioids prescribed that were for oxycodone extended release. The exposure of interest was media attention defined as the number of articles published each month in 27 North American newspapers. Variations in media effects by provider characteristics (specialty, prescribing volume, and region) were assessed. Within-provider changes in the prescribing of oxycodone extended release in Nova Scotia were observed, and they followed changes in media coverage. Oxycodone extended release prescribing rose steadily prior to receiving media attention. Following peak media attention in the United States, the prescribing of oxycodone extended release slowed. Likewise, following peak coverage in Canadian newspapers, the prescribing of oxycodone extended release declined. These patterns were observed across prescriber specialties and by prescriber volume, though the magnitude of change in prescribing varied. This study demonstrates that print media reporting of oxycodone extended release in North American newspapers, and its continued portrayal as a social problem, coincided with reductions in the prescribing of oxycodone extended release by physicians in Nova Scotia.

    The effects of 16 aliphatic aldehydes with 3-10 carbons on the growth and patulin production of Penicillium expansum were examined. When P. expansum spores were inoculated into apple juice broth, some alkenals, including 2-propenal, (E)-2-butenal, (E)-2-pentenal, and (E)-2-hexenal, inhibited fungal growth and patulin production. Their minimal inhibitory concentrations were 5, 50, 80, and 80 µg/mL respectively. Vital staining indicated that these alkenals killed mycelia within 4 h. Treatment of the spores with these aldehydes also resulted in rapid loss of germination ability, within 0.5-2 d. On the other hand, aliphatic aldehydes with 8-10 carbons significantly enhanced patulin production without affecting fungal growth: 300 µg/mL of octanal and 100 µg/mL of (E)-2-octenal increased the patulin concentrations in the culture broth by as much as 8.6- and 7.8-fold as compared to that of the control culture respectively. The expression of the genes involved in patulin biosynthesis in P. expansum was investigated in mycelia cultured in apple juice broth containing 300 µg/mL of octanal for 3.5, 5, and 7 d. Transcription of the msas gene, encoding 6-methylsalicylic acid synthase, which catalyzed the first step in the patulin biosynthetic pathway was remarkably high in the 3.5-d and 5-d-old cultures as compared with the control. However, octanal did not any increase the transcription of the msas in the 7-d-old culture or that of the other two genes, IDH and the peab1, in culture. Thus the enhanced patulin accumulation with supplementation with these aldehydes is attributable to the increased amount of the msas transcript.

    The effects due to Candidatus Liberibacter infection, commonly called citrus greening or Huanglongbing (HLB), on volatile and nonvolatile components of orange juices, OJ, were examined using GC-MS and high-performance liquid chromatography (HPLC). HLB symptomatic, asymptomatic, and control "Hamlin" and "Valencia" oranges were harvested from December to May during the 2007 to 2008 harvest season. Brix/acid levels in control and asymptomatic juices were similar but symptomatic juices were as much as 62% lower than control juices. No bitter flavanone neohesperidosides were detected and polymethoxyflavone concentrations were well below bitter taste thresholds. Limonin concentrations were significantly higher (91% to 425%) in symptomatic juice compared to control but still below juice bitterness taste thresholds. Juice terpenes, such as gamma-terpinene and alpha-terpinolene, were as much as 1320% and 62% higher in symptomatic juice than control. Average ethyl butanoate concentrations were 45% lower and average linalool was 356% higher in symptomatic Valencia OJ compared to control. Symptomatic Valencia OJ had on average only 40% the total esters, 48% the total aldehydes, and 33% as much total sesquiterpenes as control juice. Total volatiles between control and symptomatic juices were similar due to elevated levels of alcohols and terpenes in symptomatic juice. There were no consistent differences between asymptomatic and control juices. The chemical composition of juice from HLB/greening symptomatic fruit appears to mimic that of juice from less mature fruit. The reported off-flavor associated with symptomatic juices probably stem from lower concentrations of sugars, higher concentrations of acid as all known citrus bitter compounds were either below taste thresholds or absent.

    Full Text Available More than 80 million Americans have hypertension (HTN, and African Americans (AAs are disproportionately affected. AAs also have lower rates of adherence to HTN treatment. It is important to understand AAs’ perceptions of adherence to develop effective interventions. The aim of this study is to examine AAs’ perceptions of adherence to medications and lifestyle changes prescribed to treat HTN. In this qualitative study, we used purposive sampling to recruit Southern AAs with HTN aged 21 and older from a free, faith-based clinic. We recorded individual, in-person interviews about perceptions related to adherence to treatment of HTN and analyzed verbatim transcripts using content analysis and constant comparison. We also conducted medical record audits. Twenty-nine AAs participated (52% female, 38% were <50 years of age, 52% had taken anti-HTN medications for ≥5 years. Audits indicated that 65% had uncontrolled HTN during the previous year. Two main themes included causes of HTN and ways to improve blood pressure. Perceived causes of HTN included diet, stress, unhealthy actions, genes, and obesity. Ways to improve HTN included using cultural treatments “passed down,” increasing exercise, reducing stress, and losing weight. Many reported using home remedies to control HTN, including drinking pickle juice. More than half of this sample had uncontrolled HTN. They identified influences of culture on perceptions of adherence including causes and treatment of HTN, and possibly detrimental home remedies. It is imperative that clinicians identify culturally appropriate interventions for this high-risk group.

    Research suggests that pharmaceutical marketing influences prescribing and may cause cognitive dissonance for prescribers. This work has primarily been with physicians and physician-trainees. Questions remain regarding why prescribers continue to meet with pharmaceutical representatives (PRs). To describe the reasons that prescribers from various health professions continue to interact with PRs despite growing evidence of the influence of these interactions. Multi-disciplinary focus groups with 61 participants held in practice settings and at society meetings. Most prescribers participating in our focus groups believe that overall PR interactions are beneficial to patient care and practice health. They either trust the information from PRs or feel that they are equipped to evaluate it independently. Despite acknowledgement of study findings to the contrary, prescribers state that they are able to effectively manage PR interactions such that their own prescribing is not adversely impacted. Prescribers describe few specific strategies or policies for these interactions, and report that policies are not consistently implemented with all members of a clinic or institution. Some prescribers perceive an inherent contradiction between academic centers and national societies receiving money from pharmaceutical companies, and then recommending restriction at the level of the individual prescriber. Prescribers with different training backgrounds present a few novel reasons for these meetings. Despite evidence that PR detailing influences prescribing, providers from several health professions continue to believe that PR interactions improve patient care, and that they can adequately evaluate and filter information presented to them by PRs. Focus group comments suggest that cultural change is necessary to break the norms that exist in many settings. Applying policies consistently, considering non-physician members of the healthcare team, working with trainees, restructuring

    We prove that a module M is cofinitely weak supplemented or briefly cws (i.e., every submodule N of M with M/N finitely generated, has a weak supplement) if and only if every maximal submodule has a weak supplement. If M is a cws-module then every M-generated module is a cws-module. Every module is cws if and only if the ring is semilocal. We study also modules, whose finitely generated submodules have weak supplements.

    The creation of advanced nursing roles in diabetes management, with specific skills such as nurse prescribing, has resulted in nurses taking on roles that have traditionally been associated with doctors. We aimed to examine the effectiveness of nurse-led clinics, in which nurses were involved in prescribing, on haemoglobin A1c (HbA1c) among people with type 2 diabetes. We systematically searched the literature, Medline, the Cochrane Central Register of Controlled Trials (CENTRAL), EMBASE and Allied Health Literature database guide (CINAHL) databases, to identify randomised controlled trials (RCTs) assessing the effect of nurse prescribers on HbA1c. We focused on randomised controlled trials which compared nurse prescriber interventions with usual care in adults aged 18 years or over with a diagnosis of type 2 diabetes. The main outcome measure was change in HbA1c levels. We performed a random effects model meta-analysis to assess the pooled effect size of the intervention. Studies were divided into two groups according to the role of nurses in the intervention. In one group, the nurses supplemented a team, as an add-on to usual care; in the other group, they worked independently, and were compared directly to a doctor. Nine RCTs were identified and included in this study. All studies were from developed countries, with a medium risk of bias and a moderate heterogeneity between studies. In the five RCTs in which nurse prescribers supplemented a team, there was no significant difference in change of HbA1c compared to usual care (-0.34 percentage points; 95% CI: -0.71, 0.02). In the four RCTs in which nurses replaced doctors, the outcomes of nurse prescribers were comparable to those of doctors. No data on adverse events were available. There was no clear evidence of benefit on glycaemic control, when nurses who undertake prescribing work alongside a doctor and other practitioners. However, in those studies in which nurses replaced physicians, the glycaemic control

    Red and white grape juices were treated with high hydrostatic pressure (HHP) at three different pressures, temperature and time values to investigate the effects of HHP on natural microflora and some quality attributes of the juices. Increased pressure, temperature and time showed significant effect on the microbial reduction and no microbial growth were observed in HHP-treated grape juices up to 90 days. HHP had little or no effect on pH and color of the juices. Although 5-hydroxymethylfurfural (HMF) formation was observed in heat pasteurized samples, no HMF was detected in HHP-treated juices. This study demonstrated that HHP could be used as an alternative to heat treatment.

    Full Text Available This work shows the application of ¹H NMR spectroscopy and chemometrics for quality control of grape juice. A wide range of quality assurance parameters were assessed by single ¹H NMR experiments acquired directly from juice. The investigation revealed that conditions and time of storage should be revised and indicated on all labels. The sterilization process of homemade grape juices was efficient, making it possible to store them for long periods without additives. Furthermore, chemometric analysis classified the best commercial grape juices to be similar to homemade grape juices, indicating that this approach can be used to determine the authenticity after adulteration.

    The aim of this study was to find simple objective analytical methods to assess the adulteration of orange juice by grapefruit juice. The adulterations by addition of grapefruit juice were studied by 3D-front-face fluorescence spectroscopy followed by Independent Components Analysis (ICA) and by classical methods such as free radical scavenging activity and total flavonoid content. The results of this study clearly indicate that frauds by adding grapefruit juice to orange juice can be detected at percentages as low as 1%.

    A range of health workforce strategies are needed to address health service demands in low-, middle- and high-income countries. Non-medical prescribing involves nurses, pharmacists, allied health professionals, and physician assistants substituting for doctors in a prescribing role, and this is one approach to improve access to medicines. To assess clinical, patient-reported, and resource use outcomes of non-medical prescribing for managing acute and chronic health conditions in primary and secondary care settings compared with medical prescribing (usual care). We searched databases including CENTRAL, MEDLINE, Embase, and five other databases on 19 July 2016. We also searched the grey literature and handsearched bibliographies of relevant papers and publications. Randomised controlled trials (RCTs), cluster-RCTs, controlled before-and-after (CBA) studies (with at least two intervention and two control sites) and interrupted time series analysis (with at least three observations before and after the intervention) comparing: 1. non-medical prescribing versus medical prescribing in acute care; 2. non-medical prescribing versus medical prescribing in chronic care; 3. non-medical prescribing versus medical prescribing in secondary care; 4 non-medical prescribing versus medical prescribing in primary care; 5. comparisons between different non-medical prescriber groups; and 6. non-medical healthcare providers with formal prescribing training versus those without formal prescribing training. We used standard methodological procedures expected by Cochrane. Two review authors independently reviewed studies for inclusion, extracted data, and assessed study quality with discrepancies resolved by discussion. Two review authors independently assessed risk of bias for the included studies according to EPOC criteria. We undertook meta-analyses using the fixed-effect model where studies were examining the same treatment effect and to account for small sample sizes. We compared

    Trace metal levels in selected fruit juices and carbonated beverages purchased in Lagos, Nigeria were determined using atomic absorption spectrophotometer (Unicam model 969) equipped with SOLAAR 32 windows software. Fruit juices analysed were grape, pineapple, apple, orange, lemon juices and their brand names were used. Some carbonated drinks were also evaluated for metal levels. Trace metals investigated were Cr, Cu, Pb, Mn, Ni, Zn, Sn, Fe, Cd and Co. Trace metal contents of fruit juices were found to be more than the metallic contents of carbonated beverages. Pb level in the fruit juices ranged from 0.08 to 0.57 mg/l but was not detected in the carbonated drinks. Concentrations of Pb in lemon juice and Mn in pineapple juice were relatively high. Cd and Co were not detected in the selected juices and beverages. Additionally, Pb, Cu, Cr and Fe were not detected in canned beverages but were present in bottled beverages. However, the metal levels of selected fruit juices and carbonated beverages were within permissible levels except for Mn in pineapple juice and Pb in lemon juice.

    Full Text Available The ethanol production by fermentation of sweet-stalk sorghum juice is affected by the juice composition and the capability of the yeast strain to ferment it. Eight yeast strains were tested on their growth and ethanol fermentation abilities in sweet-stalk sorghum juices extracted from three cultivars of sweet sorghum. The best specific growth rate of the yeast strains grown aerobically in the yeast extract peptone dextrose (YEPD broth and the sweet-stalk sorghum juices of KCS105, FS501, and FS902 cultivars, were achieved by OUT7903, OUT7913, OUT7903, and OUT7027 yeast strains, respectively. However, the best specific CO2 evolution rate of the yeast strain during fermentation of the juices was achieved by OUT7027 yeast strains. The highest ethanol concentration, ethanol yield, and sugar conversion efficiency (SCE were obtained by strain OUT7921 when it was employed to ferment sweet-stem sorghum juice of FS902 cultivar. It was also observed that the juice extracted from sweet-stalk sorghum of FS902 cultivar is the most suitable medium for all yeast strains to achieve their best fermentation abilities. Thus, it is likely that the growth and ethanol production ability of a yeast strain in sweet-stalk sorghum juice depend on the physiological responses of the yeasts to nutrientcomposition of the sorghum juice and the sorghum cultivar from which the juice was extracted.Key words : Sweet-stalk sorghum juice, ethanol, fermentation, yeast

    The current study reports the preparation and stabilization of novel functional drinks based on fruit and vegetable juices incorporating bacterial cellulose from Acetobacter xylinum. Pineapple, musk melon, carrot, tomato, beet root and a blend juice containing 20 % each of carrot and tomato juice with 60 % beet root juice has been studied. These juices have been stabilized over a storage period of 90 days at 28 °C, by the use of nisin and maintaining a low pH circumventing the need for any chemical preservatives or refrigeration. Instrumental color values have been correlated with the pigment concentrations present in the fresh as well as stored juices. There was 36, 72 and 60 % loss of total carotenoids in the case of carrot, pineapple and musk melon juices respectively while the lycopene content remained unchanged after 90 days of storage. The betanin content decreased 37 % in the case of beetroot juice and 25 % in the case of beetroot juice blended with carrot and tomato juices. Sensory analysis has revealed a clear preference for the beetroot blended mixed juice.

    Full Text Available Following Food and Drug Administration (FDA approval, many drugs are prescribed for non-FDA-approved ("off-label" uses. If substantial evidence supports the efficacy and safety of off-label indications, manufacturers can pursue formal FDA approval through supplemental new drug applications (sNDAs. We evaluated the effect of FDA determinations on pediatric sNDAs for antipsychotic drugs on prescribing of these products in children.Retrospective, segmented time-series analysis using new prescription claims during 2003-2012 for three atypical antipsychotics (olanzapine, quetiapine, ziprasidone. FDA approved the sNDAs for pediatric use of olanzapine and quetiapine in December 2009, but did not approve the sNDA for pediatric use of ziprasidone.During the months before FDA approval of its pediatric sNDA, new prescriptions of olanzapine decreased for both children and adults. After FDA approval, the increase in prescribing trends was similar for both age groups (P = 0.47 for schizophrenia and bipolar disorder; P = 0.37 for other indications. Comparable decreases in use of quetiapine were observed between pediatrics and adults following FDA approval of its pediatric sNDA (P = 0.88; P = 0.63. Prescribing of ziprasidone decreased similarly for pediatric and adult patients after FDA non-approval of its pediatric sNDA (P = 0.61; P = 0.79.The FDA's sNDA determinations relating to use of antipsychotics in children did not result in changes in use that favored the approved sNDAs and disfavored the unapproved sNDA. Improved communication may help translate the agency's expert judgments to clinical practice.

    Consumer demand for pomegranate juice has considerably grown, during the last years, for its potential health benefits. Since it is an expensive functional food, cheaper fruit juices addition (i.e., grape and apple juices) or its simple dilution, or polyphenols subtraction are deceptively used. At present, time-consuming analyses are used to control the quality of this product. Furthermore these analyses are expensive and require well-trained analysts. Thus, the purpose of this study was to propose a high-speed and easy-to-use shortcut. Based on UV-VIS spectroscopy and chemometrics, a screening method is proposed to quickly screening some common fillers of pomegranate juice that could decrease the antiradical scavenging capacity of pure products. The analytical method was applied to laboratory prepared juices, to commercial juices and to representative experimental mixtures at different levels of water and filler juices. The outcomes were evaluated by means of multivariate exploratory analysis. The results indicate that the proposed strategy can be a useful screening tool to assess addition of filler juices and water to pomegranate juices. Copyright © 2012 Elsevier Ltd.

    Lactic acid is one of the most important building blocks for the production of bioplastic. Many investigations have been conducted to reduce the lactic acid production costs. In this work, the focus was put on the application of legume pressed juice or green juice as nutrient source. The pressed juice was utilized directly without prior pre-treatment and sterilization. Using two different alfalfa green juices and a clover green juice from two different harvest years as sole nutrients, non-sterile fermentations were performed at 52°C and pH 6.0 with a thermotolerant strain Bacillus coagulans AT107. The results showed that alfalfa green juices generally were more suitable for high lactic acid production than clover green juices, presumably due to the higher nitrogen content. A final titer of 98.8g/L after 30h with l(+)-lactic acid purity of >99% was obtained.

    Orange juice consumption can promote lower levels of oxidative stress and inflammation due to the antioxidant activity of citrus flavonoids and carotenoids. In addition, red-fleshed sweet orange juice (red orange juice) also contains lycopene. This study investigated the effects of red orange juice consumption on risk factors for metabolic syndrome. Volunteers consumed red orange juice daily for 8 weeks, with clinical and biochemical assessments performed at baseline and on the final day. There was no change in the abdominal obesity, but low-density lipoprotein cholesterol, C-reactive protein decreased, while there was an increase of the antioxidant activity in serum after red orange juice consumption. Insulin resistance and systolic blood pressure were reduced in normal-weight volunteers, while diastolic blood pressure decreased in overweight volunteers after intervention. Red orange juice showed anti-inflammatory, antioxidant, and lipid-lowering properties that may prevent the development of metabolic syndrome.

    In this study, longan juice was subjected to a high pressure of 500 MPa for 30 min and compared with a juice pasteurized at 90°C/2 min. Probiotic Lactobacillus casei 01 was fortified into both juices and the shelf life of these products was studied. Their bioactive components such as ascorbic acid, gallic acid and ellagic acid were analyzed by High Performance Liquid Chromatography (HPLC). Total phenolic compounds and 2,2-Diphenyl-1-picrythydrazyl radical-scavenging activity were determined by colorimetric and spectrophotometric methods. It was found that the pressurized longan juice retained higher amounts of bioactive compounds than the pasteurized juice. In terms of storage stability, bioactive compounds in both processed juices decreased according to the increase in storage time. The survivability of probiotic L. casei 01 in both processed juices declined from 9 to 6 log CFU/mL after 4 weeks of storage.

    Full Text Available The aim of this study was to analyze the effect of ohmic heating and ultrasound on quality parameters of red grapefruit juice (Citrus paradisi. The juice was processed by ohmic heating (120 V, 70 and 80 °C, 30 and 180 s and ultrasound (amplitude of 40 and 50 µm, and 2 and 10 minutes. The treatments did not significantly affect the cloud value, pH, non-enzymatic browning and colorimetric parameters. The taste was the determining parameter in the choice of juice by consumers. Juices processed with ohmic heating showed sensory characteristics more like the natural juice. The best juice was obtenied by processing with OH at 70 °C for 30 s. According to the present study it could be suggested that red grapefruit juice processed by ohmic heating could improve sensory characteristics without changes in quality parameter.

    This article presents a framework for prescribing, ordering, and adapting a new wheelchair, focusing on individual, environmental and wheelchair factors that must be taken into consideration to ensure optimal function. A review and analysis was conducted of all factors relevant to the transition to a new wheelchair. Without appropriate planning and implementation, this transition can result in unnecessary expenses, duplication of effort, and possibly even injury to the user and abandonment of the wheelchair. Recommendations are provided to manufacturers, therapists, technicians, users, insurers and physicians, who must work together throughout this process. To the extent feasible, the authors suggest that major changes from the previous wheelchair should be avoided, particularly for people with substantial functional limitations. Therapists and technicians must measure the user accurately, and anticipate those factors that can impede a smooth transition. Insurers and other payors must recognize that changing wheelchairs will often require substantial professional assistance, including several fittings to adjust the new chair to the needs of the user. Additional research and case reporting on outcomes of adjusting to a new wheelchair appear warranted.

  18. Consider prescribing OCs for perimenopause use.

    Contraceptive experts advise the use of low-dose (20-35 mcg estrogen) oral contraceptives (OCs) for perimenopausal patients because of their numerous advantages over hormone replacement therapy. Benefits include effective contraception, regular menses, treatment of menorrhagia and dysmenorrhea, reduction of vasomotor symptoms, higher bone density and fewer fractures, and prevention of ovarian and endometrial cancers. Although age limits for OC use for healthy nonsmoking women have been lifted for some time, certain providers still hesitate to prescribe OCs. Moreover, epidemiological studies confirm that low-dose pills are safe for healthy, nonsmoking women with normal blood pressure. More definitive research also found that the increased risk was mainly related to smoking rather than age. Since smoking is an important risk factor in OC use, pill use by smokers over 35 years old is contraindicated. Instead, it is suggested that they use progestin-only pills, IUDs, or barrier contraceptives for birth control. Another research indicates that women who use the pill can decrease their risk of postmenopausal fractures.

    The NASA Fatigue Management Team is developing recommendations for managing fatigue during travel and for shift work operations, as Clinical Practice Guidelines for the Management of Circadian Desynchrony in ISS Operations. The Guidelines provide the International Space Station (ISS ) flight surgeons and other operational clinicians with evidence-based recommendations for mitigating fatigue and other factors related to sleep loss and circadian desynchronization. As much international travel is involved both before and after flight, the guidelines provide recommendations for: pre-flight training, in-flight operations, and post-flight rehabilitation. The objective of is to standardize the process by which care is provided to crewmembers, ground controllers, and other support personnel such as trainers, when overseas travel or schedule shifting is required. Proper scheduling of countermeasures - light, darkness, melatonin, diet, exercise, and medications - is the cornerstone for facilitating circadian adaptation, improving sleep, enhancing alertness, and optimizing performance. The Guidelines provide, among other things, prescribed travel schedules that outline the specific implementation of these mitigation strategies. Each travel schedule offers evidence based protocols for properly using the NASA identified countermeasures for fatigue. This presentation will describe the travel implementation schedules and how these can be used to alleviate the effects of jet lag and/or schedule shifts.

  20. Prescribing physical activity in primary care.

    Physical activity is a powerful weapon for individuals interested in health maintenance. Many benefits of regular physical activity are well known to the medical community including improved weight control, healthier cardiovascular system, and tighter diabetic control. Less recognized benefits of physical activity may include stronger bones, better sleep, lower blood pressure, improved mood, opportunities for personal enjoyment, cancer prevention, and even a longer lifespan. Despite these numerous incentives, less than a quarter of the U.S. population is active enough to gain the rewards (13). West Virginians are among the least physically active; more than 40% of state residents engage in no leisure time physical activity at all (15), so it is critical that physicians in the state take a much more active role in prescribing physical activity for their patients. Although more research is needed, data exists to suggest counseling by physicians does result in increased physical activity (20-23). Attention to risk factors and specific red flags can help decide when formal pre-exercise stress testing is necessary. An organized approach includes development of the mode, frequency, duration, intensity and progression of exercise by a physician who knows the patient's interests and limitations (28). The most current consensus guidelines suggest 30 minutes of moderate-intensity physical activity daily (12). Physicians need to encourage this goal during office visits and there appears to be benefit in putting specific physical activity advice in the form of a written prescription (21).
