The Impact

The impact of dietary supplementation with essential fatty acids (EFA) on recurrent respiratory infections (RRI) in children was evaluated by means of a randomized crossover double-blind study. Linoleic acid (596 mg/day) and alpha-linolenic acid (855 mg/day) as a commercial preparation or placebo (olive oil) were administered for two consecutive winter seasons (November to February, T0 – T120) to 20 children affected by RRI, aged between 36 and 49 months. Plasma levels of n-3 and n-6 metabolites increased after the administration of EFA. The number of infective episodes, days' fever and days' absence from school were reduced significantly during the observation period (extended from T120 to T180) in children receiving EFA supplementation. Our results suggest that n-3 and n-6 polyunsaturated fatty acids may play a favourable role in the defence mechanism of these subjects.

Az omega-3 zsírsav fogyasztásának növelése kedvező hatású lehet a fokozott cardiovascularis kockázatú személyek, köztük az elhízottak számára. A kedvező hatások létrejöttének feltétele az omega-3 zsírsavaknak a szervezet plazmalipideibe történő beépülése, azonban a gyermekkorban ehhez szükséges szupplementációs dózisra vonatkozóan igen kevés adat áll rendelkezésre. A jelen vizsgálatunk célja napi 1000 mg alfa-linolénsavval kiegészített étrend a plazmalipidek zsírsavösszetételére kifejtett hatásának vizsgálata volt elhízott gyermekekben. Személyek és módszerek: Ebben a placebóval kontrollált, keresztező önkontrollos, 2 × 6 hétig tartó vizsgálatban a részt vevő 9 elhízott gyermek (életkor: 13,1 [±2,5] év, testtömegindex: 31,2 [±6,2] kg/m 2 , medián [IQR]) étrendjébe speciális takarmánnyal etetett tyúkoktól származó napi 1 tojást és 50 g csirkehúst építettünk be, amivel napi 1000 mg alfa-linolénsav bevitelét tudtuk biztosítani. A plazmalipidek zsírsavösszetételét nagy felbontóképességű kapilláris gáz-folyadék kromatográfiával határoztuk meg. Eredmények: Az alfa-linolénsav-értékek emelkedő tendenciája volt megfigyelhető az alfa-linolénsavval történő szupplementációt követően a foszfolipid-, a triacil-glicerin- és a szterol-észter-frakcióban egyaránt, azonban egyik frakcióban sem volt a változás szignifikáns. A nem észterifikált zsírsavfrakcióban az alfa-linolénsav értékei szignifikánsan emelkedtek (0,11 [0,08] szemben 0,14 [0,20], tömeg%, p < 0,05), jelezve az alfa-linolénsav plazmalipidekben történő feldúsulásának a kezdetét. Következtetés: Az elhízott gyermekekben az étrend 6 héten keresztül napi 1000 mg alfa-linolénsavval történő kiegészítése csak a plazma nem észterifikált zsírsavaiban növelte szignifikánsan az omega-3 zsírsavak arányát, az észterifikált frakciókban nem volt szignifikáns hatás. Elhízott gyermekekben az omega-3-zsírsavellátottság befolyásolásához az alfa-linolénsav-szupplementáció dózisának 1 g/nap fölé történő növelése tűnik szükségesnek.

Cognitive Data

Abstract Objectives A healthy diet is essential for optimal brain health. A number of food bioactives have been linked to cognitive benefits, including phytonutrients and essential fatty acids. Here we investigated the benefits of a walnut-rich breakfast, which contained flavonoids and omega-3s, to see whether consumption of these bioactives might lead to significant cognitive improvements throughout the day. Methods A double-blind, crossover intervention study compared the effects of a breakfast containing 50g walnuts, with a nut-free, macronutrient-matched control. Participants were 32 healthy, young adults aged 18 to 30. Cognition, mood, blood, and EEG measures were recorded at baseline and 2, 4, and 6 hours postprandially. Only the cognitive data are reported here. All cognitive data were analyzed using linear mixed modeling (LMM) with baseline performance included as a covariate. Bonferroni corrected pairwise comparisons were used to investigate significant treatment effects. Results Compared to the control breakfast, the walnuts elicited significantly faster reaction times throughout the day on tasks measuring inhibition and task switching aspects of executive function. Memory recall results were mixed; slightly worse performance was observed at 2 hours following the walnut breakfast, but this was later reversed with walnuts outperforming control at 6 hours. Conclusions The findings provide evidence for reaction time benefits following a walnut-rich breakfast, with effects lasting throughout the day. The results concur with previous literature that suggests executive function effects are commonly observed in young adults following flavonoid supplementation. The memory recall effect at the final time point is consistent with previously observed benefits for both omega-3 fatty acids and flavonoids and may indicate that walnuts offer neuroprotection following long periods of cognitive demand, or that memory benefits depend upon the slower absorption of omega-3s or the delayed appearance of flavonoid metabolites. Walnuts are therefore beneficial to cognitive function in young adults after only a single, acute intake, but further investigation of precise mechanisms is needed. Funding Sources The study was funded by the California Walnut Commission, USA and pre-registered at clinicaltrials.gov.

The Impact

Use of probiotic supplements, the benefits of which have not been proven in sportspeople, is becoming more widespread among runners. The aim of this study was to evaluate the effect of a multi-strain probiotic on body composition, cardiorespiratory fitness and inflammation in the body. The randomised, double-blind study included 66 long-distance runners. The intervention factor was a multi-strain probiotic or placebo. At the initial and final stages of the study, evaluation of body composition and cardiorespiratory fitness was performed and the presence of inflammation determined. In the group of men using the probiotic, an increase in lean body mass (p = 0.019) and skeletal muscle mass (p = 0.022) was demonstrated, while in the group of women taking the probiotic, a decrease in the content of total body fat (p = 0.600) and visceral fat (p = 0.247) was observed. Maximum oxygen consumption (VO2max) increased in women (p = 0.140) and men (p = 0.017) using the probiotic. Concentration of tumour necrosis factor-alpha decreased in women (p = 0.003) and men (p = 0.001) using the probiotic and in women (p = 0.074) and men (p = 0.016) using the placebo. Probiotic therapy had a positive effect on selected parameters of body composition and cardiorespiratory fitness of study participants and showed a tendency to reduce inflammation.

Milk contains several important nutrients that are beneficial for human health. This review considers the nutritional qualities of essential fatty acids (FAs), especially omega-3 (ω-3) and omega-6 (ω-6) polyunsaturated fatty acids (PUFAs) present in milk from ruminant and non-ruminant species. In particular, the impact of milk fatty acids on metabolism is discussed, including its effects on the central nervous system. In addition, we presented data indicating how animal feeding—the main way to modify milk fat composition—may have a potential impact on human health, and how rearing and feeding systems strongly affect milk quality within the same animal species. Finally, we have presented the results of in vivo studies aimed at supporting the beneficial effects of milk FA intake in animal models, and the factors limiting their transferability to humans were discussed.

Background: Our study aimed to assess the efficacy of 0.1% Octenidine mouthwash as an anti-plaque agent and to assess its effect on gingival inflammation and staining of teeth when compared to 0.2% chlorhexidine gluconate by evaluating the impact on plaque and gingival inflammation as well as on microbial load. Materials and Methods: A three week double blind study was conducted on 69 subjects, aged 20-50 years, with moderate to severe gingivitis. The study population was divided into three groups with 23 subjects in each group: Group A - control subjects received only scaling, Group B received 0.2% chlorhexidine gluconate in addition to scaling and Group C received 0.1% Octenidine mouthwash along with scaling. Clinical and microbiological parameters were recorded at baseline, on 14th day and on 21st day. Subjective and objective criteria were assessed on the 14th day and 21st day. Results: There was a statistically significant reduction in all the tested parameters within all the three groups and between the groups from baseline to 21st day. The highest mean reduction in all the parameters was seen in subjects using 0.1% Octenidine. On comparison with the control group, subjects using the mouthwashes (Group B and Group C) had better improvement in clinical and microbiological parameters from baseline to 21st day. On comparison with chlorhexidine, Octenidine mouthwash significantly reduced plaque (p<0.05) and showed better patient acceptability. However, it was comparable to chlorhexidine in other two tested parameters. Conclusion: Owing to Octenidine’s pronounced and comparable antibacterial properties, it can be a promising candidate for the use in antiseptic mouthwashes.

Abstract BACKGROUND Pain management following major spine surgery requires high doses of opioids and is associated with a risk of opioid-induced constipation. Peripheral mu-receptor antagonists decrease the gastrointestinal complications of perioperative systemic opioid administration without antagonizing the analgesic benefits of these drugs. OBJECTIVE To investigate the impact of alvimopan in opioid-naive patients undergoing major spine surgery. METHODS Patients undergoing >3 levels of thoracic and/or lumbar spine surgery were enrolled in this prospective, randomized, double-blind study to receive either alvimopan or placebo prior to and following surgery. Opioid consumption; pain scores; and time of first oral intake, flatus, and bowel movement were recorded. RESULTS A total of 24 patients were assigned to the active group and 25 were assigned to the placebo group. There was no significant difference in demographics between the groups. Postoperatively, the alvimopan group reported earlier time to first solid intake [median (range): alvimopan: 15 h (3-25) vs placebo: 17 h (3-46), P < .001], passing of flatus [median (range): alvimopan: 22 h (7-63) vs placebo: 28 h (10-58), P < .001], and first bowel movement [median (range): alvimopan: 50 h (22-80) vs placebo: 64 h (40-114), P < .001]. The alvimopan group had higher pain scores (maximum, minimum, and median); however, there was no significant difference between the groups with postoperative opioid use. CONCLUSION This study shows that the perioperative use of alvimopan significantly reduced the time to return of bowel function with no increase in postoperative opioid use despite a slight increase in pain scores.

Omega-3 fatty acids (Alpha-linolenic acid) and omega-6 fatty acids (Linoleic acid) are a group of essential fatty acids. Essential fatty acids are fatty acids that cannot be synthesized by the body so that must be supplied from the diet. One of the sources of essential fatty acids is derived from fish oil. This study aims to determine the effect of Crude Fish Oil (CFO) in the feed to EPA and DHA content in penaeid shrimp meat. The research method used was a completely randomized design. The treatments used are the varying content of Crude Fish Oil (CFO), which are P0 (0%), P1 (2%), P2 (4%), P3 (6%), and P4 (8%). The results of the study showed significant differences (p <0.05) on the content of EPA and DHA in penaeid shrimp meat. The highest content of EPA and DHA found in P4 treatment (8%) and the lowest at P0 treatment (0%). The use of CFO in penaeid shrimp feed need further study related to the growth of shrimps and prawns reproductive cycle to increase the productivity of penaeid shrimp. CFO on feed should be used at a dose of 6%.

The Impact

TPS529 Background: This phase III trial will compare the impact of consuming Specialized IMmunonutrition (SIM) to oral nutritional support on postoperative complications after radical cystectomy. Specialized IMmunonutrition is fortified with nutrients (L-arginine, omega-3 fatty acids, dietary nucleotides, and vitamin A) that have immediate effects on immune and inflammatory responses, muscle sparing, and wound healing after surgery. Methods: Two hundred patients will be randomized in a 1:1 fashion to one of two arms. Subjects will be stratified by diversion type (neobladder vs. ileal conduit) and whether the patient had neoadjuvant chemotherapy (any vs. none) to balance the intervention assignment according to important prognostic factors. Nutrition drinks are given three times a day for 5 days before and 5 days after surgery. The primary endpoint is 30 day overall complication rate. Two hundred patients gives 80% power to detect an absolute reduction of 23% in the 30 day overall complication rate (from 65% down to 42%). Secondary endpoints will assess infections, muscle mass, readmissions, quality of life, recurrence, DFS, OS, immune response, cytokines, amino acids, and fatty acids. The trial is testing a high yield, low-risk, low-cost strategy to improve the outcome of patients with bladder cancer who undergo cystectomy. Funding: NIH/NCI/DCP grant award UG1CA189974.
