Change in Micronutrient Intake among People with Relapsing-Remitting Multiple Sclerosis Adapting the Swank and Wahls Diets: An Analysis of Weighed Food Records. Nutrients 2021; 13:nu13103507. [PMID: 34684508 PMCID: PMC8540533 DOI: 10.3390/nu13103507] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/29/2021] [Revised: 09/27/2021] [Accepted: 10/01/2021] [Indexed: 12/18/2022] Open
Abstract
The low-saturated fat (Swank) and modified Paleolithic elimination (Wahls) diets have shown promise for MS symptoms; however, due to their restriction of specific foods, inadequate intake of micronutrients is concerning. Therefore, as part of a randomized trial, weighed food records were collected on three consecutive days and were used to evaluate the intake of micronutrients among people with relapsing remitting MS adapting these diets. After randomization to either the Swank or Wahls diets, diet education and support was provided by registered dietitians at baseline and throughout the first 12 weeks of the intervention. Usual intake of each micronutrient was estimated and then evaluated with the EAR-cut point method. At 12 weeks, the Swank group had significant reductions in the proportion with inadequate intake from food for vitamins C, D, and E, while the Wahls group had significant reductions for magnesium and vitamins A, C, D, and E. However, the proportion with inadequate intake significantly increased for calcium, thiamin, and vitamin B12 in the Wahls group and for vitamin A in the Swank group. Inclusion of intake from supplements reduced the proportion with inadequate intake for all micronutrients except calcium among the Wahls group but increased the proportion with excessive intake for vitamin D and niacin among both groups and magnesium among the Swank group. Both diets, especially when including intake from supplements, are associated with reduced inadequate intake compared to the normal diet of people with relapsing remitting MS.

Effect of Lactobacillus fermentum HFY03 on the Antifatigue and Antioxidation Ability of Running Exhausted Mice. OXIDATIVE MEDICINE AND CELLULAR LONGEVITY 2021; 2021:8013681. [PMID: 34621465 PMCID: PMC8492249 DOI: 10.1155/2021/8013681] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 07/25/2021] [Accepted: 09/07/2021] [Indexed: 02/07/2023]
Abstract
Yak yogurt is mainly produced in Qinghai-Tibet Plateau. It is a kind of naturally fermented dairy product. It contains abundant microorganisms. Lactobacillus fermentum (LF) HFY03 is a lactic acid bacteria derived from it. Our main research content is to study the influence of LF-HFY03 on the antifatigue and antioxidation ability of running exhausted mice. We gave different doses of LF-HFY03 to mice by gavage for 4 weeks. We selected vitamin C as the positive control group, mainly to study the relationship between antioxidant capacity and fatigue resistance and LF-HFY03 in mice with running exhaustion. The results showed that LF-HFY03 and vitamin C could significantly improve the running time of mice. And with the increase in LF-HFY03 concentration, the exhaustion time of mice was also extended. LF-HFY03 can reduce the content of urea nitrogen and lactic acid and also can increase the content of free fatty acids and liver glycogen. The levels of alanine aminotransferase, serum creatine kinase, and aspartate aminotransferase in mice decreased gradually as the antioxidant peptide level of walnut albumin increased. LF-HFY03 can reduce malondialdehyde (MDA) levels in a quantification-dependent manner and can also increase catalase (CAT) and superoxide dismutase (SOD) levels. LF-HFY03 can also increase the expressions of CAT mRNA, Cu/Zn-SOD, and Mn-SOD in the liver of mice. At the same time, LF-HFY03 can also increase the expression of protein of threonine transporter 1 (AST1)/alanine/cysteine/serine, mRNA, nNOS, and eNOS. At the same time, the solution could reduce the expression of TNF-α, syncytin-1, and inducible nitric oxide synthase (iNOS). The results showed that LF-HFY03 has a high development and application prospect as an antifatigue probiotic nutritional supplement.

Anti-Fatigue Effect of a Dietary Supplement from the Fermented By-Products of Taiwan Tilapia Aquatic Waste and Monostroma nitidum Oligosaccharide Complex. Nutrients 2021; 13:1688. [PMID: 34063516 PMCID: PMC8156273 DOI: 10.3390/nu13051688] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/25/2021] [Revised: 05/08/2021] [Accepted: 05/10/2021] [Indexed: 11/16/2022] Open
Abstract
The Taiwan Tilapia is an important aquaculture product in Taiwan. The aquatic by-products generated during Tilapia processing, such as fish bones and skin, are rich in minerals and protein. We aimed to explore the effect of a dietary supplement, comprising a mixture of fermented Tilapia by-products and Monostroma nitidum oligosaccharides as the raw materials, combined with physical training on exercise performance and fatigue. We used a mouse model that displays a phenotype of accelerated aging. Male senescence-accelerated mouse prone-8 (SAMP8) mice were divided into two control groups-with or without physical training-and supplemented with different doses (0.5 times: 412 mg/kg body weight (BW)/day; 1 time: 824 mg/kg BW/day; 2 times: 1648 mg/kg BW/day) of fermented Tilapia by-products and Monostroma nitidum oligosaccharide-containing mixture and combined with exercise training groups. Exercise performance was determined by testing forelimb grip strength and with a weight-bearing exhaustive swimming test. Animals were sacrificed to collect physical fatigue-related biomarkers. Mice dosed at 824 or 1648 mg/kg BW/day showed improvement in their exercise performance (p < 0.05). In terms of biochemical fatigue indicators, supplementation of 824 or 1648 mg/kg BW/day doses of test substances could effectively reduce blood urea nitrogen concentration and lactate concentration and increase the lactate ratio (p < 0.05) and liver glycogen content post-exercise (p < 0.05). Based on the above results, the combination of physical training and consumption of a dietary supplementation mixture of fermented Tilapia by-products and Monostroma nitidum oligosaccharides could improve the exercise performance of mice and help achieve an anti-fatigue effect.

Supplementation with embryo chicken egg extract improves exercise performance and exerts anti-fatigue effects via AMPK/mTOR signalling pathway in mice. JOURNAL OF THE SCIENCE OF FOOD AND AGRICULTURE 2021; 101:1411-1418. [PMID: 32835411 DOI: 10.1002/jsfa.10754] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/25/2019] [Revised: 06/22/2020] [Accepted: 08/24/2020] [Indexed: 06/11/2023]
Abstract
BACKGROUND Embryo chicken egg is a nutritional supplement that has been used to enhance physical fitness and promote wound healing according to traditional Chinese medicine for many years. In this study, we evaluated the effects of embryo chicken egg extract (ECE) on the exercise performance and fatigue in mice and the underlying mechanisms. RESULTS The results indicated that ECE can prolong the exhaustive swimming time, decrease lactic acid, blood urea nitrogen, creatine kinase, and malondialdehyde levels, and increase superoxide dismutase, glutathione peroxidase, and glycogen levels. Additionally, ECE can also regulate the balance of oxidative stress via the adenosine monophosphate activated protein kinase/mammalian target of rapamycin signalling pathway. CONCLUSION Taken together, these results showed that ECE can improve exercise performance and reduce physical fatigue in mice, which indicates that ECE can be used as a potential supplement to reduce physical fatigue. © 2020 Society of Chemical Industry.

Nutrition intervention is beneficial to the quality of life of patients with gastrointestinal cancer undergoing chemotherapy in Vietnam. Cancer Med 2021; 10:1668-1680. [PMID: 33550719 PMCID: PMC7940238 DOI: 10.1002/cam4.3766] [Citation(s) in RCA: 12] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/18/2020] [Revised: 01/19/2021] [Accepted: 01/20/2021] [Indexed: 12/24/2022] Open
Abstract
INTRODUCTION The best treatment therapy for gastrointestinal cancer patients is assessed by the improvement of health status and quality of life (QoL) after treatments. Malnutrition is related to loss of muscle strengths which leads to lower physical performance and emotional status. Thus, this study aimed to estimate the effects of nutritional interventions on the improvement of QoL among gastrointestinal patients undergoing chemotherapy in Vietnam. METHODS A quasi-experiment with intervention and control groups for pre- and post-intervention assessment was carried out at the Department of Oncology and Palliative Care-Hanoi Medical University Hospital from 2016 to 2019. Sixty gastrointestinal cancer patients were recruited in each group. The intervention regimen consisted of nutritional counseling, a specific menu with a recommended amount of energy, protein, and formula milk used within 2 months. Nutritional status and QoL of patients were evaluated using The Scored Patient-Generated Subjective Global Assessment (PG-SGA) and The European Organization for Research and Treatment of Cancer (EORTC). The difference in differences (DiD) method was utilized to estimate the outcome between control and intervention groups. RESULTS After the intervention, patients of the intervention group had better changes in scores of global health status (Coef =16.68; 95% CI =7.90; 25.46), physical (Coef =14.51; 95% CI =5.34; 23.70), and role functioning (Coef =14.67; 95% CI =1.63; 27.70) compared to the control group. Regarding symptom scales, the level of fatigue, pain, and insomnia symptoms significantly reduced between pre- and post-intervention in the intervention group. In addition, living in urban areas, defined as malnourished and having low prealbumin levels, were positively associated with the lower global health status/QoL score. CONCLUSION Nutritional therapy with high protein was beneficial to the improvement in QoL, physical function and the reduction of negative symptoms among gastrointestinal cancer patients. Early individualized nutritional support in consultation with professional dietitians during chemotherapy plays an integral part in enhancing the QoL and better treatment prognosis.

Effect of Food Containing Paramylon Derived from Euglena gracilis EOD-1 on Fatigue in Healthy Adults: A Randomized, Double-Blind, Placebo-Controlled, Parallel-Group Trial. Nutrients 2020; 12:nu12103098. [PMID: 33053626 PMCID: PMC7601521 DOI: 10.3390/nu12103098] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/11/2020] [Revised: 10/08/2020] [Accepted: 10/08/2020] [Indexed: 12/16/2022] Open
Abstract
Euglena gracilis EOD-1, a kind of microalgae, is known to contain a high proportion of paramylon, a type of β-1,3-glucan. Paramylon derived from E. gracilis EOD-1 is presumed to suppress cellular oxidative injury and expected to reduce fatigue and fatigue sensation. Therefore, we aimed to examine whether food containing paramylon derived from E. gracilis EOD-1 (EOD-1PM) ingestion reduced fatigue and fatigue sensation in healthy adults. We conducted a randomized, double-blind, placebo-controlled, parallel-group comparison study in 66 healthy men and women who ingested a placebo or EOD-1PM daily for 4 weeks (daily life fatigue). Furthermore, at the examination days of 0 and 4 weeks, tolerance to fatigue load was evaluated using mental tasks (task-induced fatigue). We evaluated fatigue sensation using the Visual Analogue Scale, the work efficiency of the advanced trail making test and measured serum antioxidant markers. The EOD-1PM group showed significantly lower levels of physical and mental fatigue sensations and higher levels of work efficiency as well as serum biological antioxidant potential levels than the placebo group. These results indicate that EOD-1PM ingestion reduced fatigue and fatigue sensation, which may be due to an increase in antioxidant potential and maintenance of selective attention during work.

Lipid profile is associated with decreased fatigue in individuals with progressive multiple sclerosis following a diet-based intervention: Results from a pilot study. PLoS One 2019; 14:e0218075. [PMID: 31211794 PMCID: PMC6581256 DOI: 10.1371/journal.pone.0218075] [Citation(s) in RCA: 20] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/27/2019] [Accepted: 05/14/2019] [Indexed: 11/18/2022] Open
Abstract
Purpose To investigate associations between lipid profiles and fatigue in a cohort of progressive multiple sclerosis (MS) patients on a diet-based multimodal intervention. Methods This pilot study included 18 progressive MS patients who participated in a prospective longitudinal study of fatigue following a diet-based multimodal intervention that included exercise, neuromuscular electrical stimulation and stress reduction. The diet recommended high intake of vegetables and fruits, encouraged consumption of animal and plant protein and excluded foods with gluten-containing grains, dairy and eggs. Fatigue was measured on the Fatigue Severity Scale (FSS) at baseline and every 3 months for 12 months. A lipid profile consisting of high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), total cholesterol (TC) and triglycerides (TG) was obtained on fasting blood samples at baseline and 12 months. Results FSS scores decreased from a baseline of 5.51 (95% CI: 4.86, 6.16) to a mean of 3.03 (95% CI: 2.23, 3.82) at 12 months (p < 0.001). At 12 months, increases in HDL-C (mean change: +6.0 mg/dl; 95% CI: 0.3, 12.0; p = 0.049) and decreases in BMI (mean change: -2.6 kg/m2; 95% CI: -3.6, -2.5; p < 0.001), LDL-C (mean change: -10.4 mg/dl; 95% CI:-19.7, -1.2; p = 0.029), TG (mean change: -29.2 mg/dl; 95% CI: -44.3, -14.2; p = 0.001), TG to HDL-C ratio (mean change: -0.6; 95% CI: -1.0, -0.3; p = 0.002) and TC to HDL-C ratio (mean change:-0.6; 95% CI: -1.0, -0.3; p = 0.003) were observed compared to baseline. Improvements in FSS were associated with increases in HDL-C (β = -0.05; 95% CI: -0.1, -0.0004; p = 0.048) and changes in TC (p = 0.005) from baseline to 12 months. Conclusions Lipid profile variables are associated with improvements in fatigue in progressive MS patients on a diet-based multimodal intervention.

Is there an effect of dietary intake on MS-related fatigue? - A systematic literature review. Mult Scler Relat Disord 2018; 25:282-291. [PMID: 30170268 DOI: 10.1016/j.msard.2018.08.017] [Citation(s) in RCA: 15] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/21/2018] [Revised: 08/08/2018] [Accepted: 08/17/2018] [Indexed: 11/30/2022]
Abstract
BACKGROUND Fatigue is considered the most common symptom of persons with multiple sclerosis MS (pwMS), occurring in up to 90% of the patients at some point with two-thirds of pwMS experience fatigue as their most disturbing symptom. Pharmacological treatment options for MS-related fatigue show only limited and contradicting results. Consequently, many pwMS search for alternative options to control the symptom. A considerable interest in dietary interventions as a means of MS symptom management has advanced in the MS community. Yet, the few empirical studies focussing on the effect of holistic dietary intake on fatigue have not been systematically examined. The aim of this review was to systematically review the effect of holistic dietary intake and the subjective perception of fatigue in adult pwMS. METHODS Embase, Medline, Web of Science, CINAHL Complete, SPORTDiscus, PsycInfo, and Rehabilitation and Sports Medicine (Ebsco Host) databases were systematically searched to locate relevant literature. Intervention trials studying the effect of a holistic dietary regimen on the subjective perception of fatigue in a sample of adult pwMS were considered for inclusion. Risk of bias was assessed using a modified Downs and Black checklist. RESULTS A total of four studies met the inclusion criteria: one single arm intervention pilot trial, one randomised controlled pilot trial, one double-blinded randomised trial, and one assessor-blinded randomised controlled trial. Interventions were low fat diets, a low fat, starchy plant food diet, and modified paleo diets and ranged from three to 12 months duration. Two studies supplying an adequate amount of folate and magnesium with the intervention diet reported relevant improvements in fatigue scores. CONCLUSION Dietary intake holds the potential to lower MS-related fatigue, but solid conclusions are not possible based on the existing evidence. Sparse evidence points towards an effect of adequate magnesium and folate intake and a trend for decreased fatigue.

Dietary approaches to treat MS-related fatigue: comparing the modified Paleolithic (Wahls Elimination) and low saturated fat (Swank) diets on perceived fatigue in persons with relapsing-remitting multiple sclerosis: study protocol for a randomized controlled trial. Trials 2018; 19:309. [PMID: 29866196 PMCID: PMC5987638 DOI: 10.1186/s13063-018-2680-x] [Citation(s) in RCA: 23] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/21/2017] [Accepted: 05/08/2018] [Indexed: 01/09/2023] Open
Abstract
BACKGROUND Fatigue is one of the most disabling symptoms of multiple sclerosis (MS) and contributes to diminishing quality of life. Although currently available interventions have had limited success in relieving MS-related fatigue, clinically significant reductions in perceived fatigue severity have been reported in a multimodal intervention pilot study that included a Paleolithic diet in addition to stress reduction, exercise, and electrical muscle stimulation. An optimal dietary approach to reducing MS-related fatigue has not been identified. To establish the specific effects of diet on MS symptoms, this study focuses on diet only instead of the previously tested multimodal intervention by comparing the effectiveness of two dietary patterns for the treatment of MS-related fatigue. The purpose of this study is to determine the impact of a modified Paleolithic and low saturated fat diet on perceived fatigue (primary outcome), cognitive and motor symptoms, and quality of life in persons with relapsing-remitting multiple sclerosis (RRMS). METHODS/DESIGN This 36-week randomized clinical trial consists of three 12-week periods during which assessments of perceived fatigue, quality of life, motor and cognitive function, physical activity and sleep, diet quality, and social support for eating will be collected. The three 12-week periods will consist of the following: 1. OBSERVATION Participants continue eating their usual diet. 2. INTERVENTION Participants will be randomized to a modified Paleolithic or low saturated fat diet for the intervention period. Participants will receive support from a registered dietitian (RD) through in-person coaching, telephone calls, and emails. 3. FOLLOW-UP Participants will continue the study diet for an additional 12 weeks with minimal RD support to assess the ability of the participants to sustain the study diet on their own. DISCUSSION Because fatigue is one of the most common and disabling symptoms of MS, effective management and reduction of MS-related fatigue has the potential to increase quality of life in this population. The results of this study will add to the evidence base for providing dietary recommendations to treat MS-related fatigue and other symptoms associated with this disease.

Dietary intake of soy and cruciferous vegetables and treatment-related symptoms in Chinese-American and non-Hispanic White breast cancer survivors. Breast Cancer Res Treat 2018; 168:467-479. [PMID: 29230660 PMCID: PMC5928523 DOI: 10.1007/s10549-017-4578-9] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/06/2017] [Accepted: 11/14/2017] [Indexed: 01/07/2023]
Abstract
PURPOSE This project was undertaken to examine the association between dietary intake of soy or cruciferous vegetables and breast cancer treatment-related symptoms among Chinese-American (CA) and Non-Hispanic White (NHW) breast cancer survivors. METHODS This cross-sectional study included 192 CA and 173 NHW female breast cancer survivors (stages 0-III, diagnosed between 2006 and 2012) recruited from two California cancer registries, who had completed primary treatment. Patient-reported data on treatment-related symptoms and potential covariates were collected via telephone interviews. Dietary data were ascertained by mailed questionnaires. The outcomes evaluated were menopausal symptoms (hot flashes, night sweats, vaginal dryness, vaginal discharge), joint problems, fatigue, hair thinning/loss, and memory problems. Associations between soy and cruciferous vegetables and symptoms were assessed using logistic regression. Analyses were further stratified by race/ethnicity and endocrine therapy usage (non-user, tamoxifen, aromatase inhibitors). RESULTS Soy food and cruciferous vegetable intake ranged from no intake to 431 and 865 g/day, respectively, and was higher in CA survivors. Higher soy food intake was associated with lower odds of menopausal symptoms (≥ 24.0 vs. 0 g/day, OR 0.51, 95% CI 0.25, 1.03), and fatigue (≥ 24.0 vs. 0 g/day, OR 0.43, 95% CI 0.22, 0.84). However, when stratified by race/ethnicity, associations were statistically significant in NHW survivors only. Compared with low intake, higher cruciferous vegetable intake was associated with lower odds of experiencing menopausal symptoms (≥ 70.8 vs. < 33.0 g/day, OR 0.50, 95% CI 0.25, 0.97) in the overall population. CONCLUSIONS In this population of breast cancer survivors, higher soy and cruciferous vegetable intake was associated with less treatment-related menopausal symptoms and fatigue.

Abstract
Low serum levels of vitamin D have been associated with fatigue in both healthy and clinical populations. Our aim was to evaluate the effect of vitamin D supplementation on fatigue in kidney transplant recipients (KTRs). In total, 137 patients after kidney transplant and 119 age- and sex-matched healthy volunteers were recruited. Serum levels of 25-hydroxyvitamin D (25(OH)D) were measured by competitive protein-binding assay. Fatigue was assessed using the subscale fatigue of the Checklist Individual Strength (CIS). Of all KTRs, 60 patients without initial vitamin D3 supplementation were started on vitamin D3 supplementation (cholecalciferol) 800 IU/d, with a follow-up examination after 3.0 to 9.0 months (mean, 6 months). Fatigue was found in 40.1% of KTRs. Serum 25(OH)D levels were inversely and independently associated with CIS scores in KTRs (P = .002). In the 60 patients who received vitamin D3 supplementation, 25(OH)D was overall increased at follow-up with 18.5% (P = .004) and CIS scores improved with 10.0% (P = .007). As vitamin D has beneficial effects on fatigue scores in KTRs, we suggest monitoring this parameter in KTRs and supplementation with vitamin D3 when vitamin D levels are low.

Abstract
Hypothyroid patients experience fatigue-related symptoms despite adequate thyroid hormone replacement. Thyroid hormone plays an essential role in carnitine-dependent fatty acid import and oxidation. We investigated the effects of L-carnitine supplementation on fatigue in patients with hypothyroidism. In total, 60 patients (age 50.0 ± 9.2 years, 3 males, 57 females) who still experienced fatigue (fatigue severity scale [FSS] score ≥ 36) were given L-carnitine (n = 30, 990 mg L-carnitine twice daily) or placebo (n = 30) for 12 weeks. After 12 weeks, although neither the FSS score nor the physical fatigue score (PFS) changed significantly, the mental fatigue score (MFS) was significantly decreased by treatment with L-carnitine compared with placebo (from 4.5 ± 1.9 to 3.9 ± 1.5 vs. from 4.2 ± 1.8 to 4.6 ± 1.6, respectively; P < 0.01). In the L-carnitine group, 75.0%, 53.6%, and 50.0% of patients showed improvement in the FSS score, PFS, and MFS, respectively, but only 20.0%, 24.0%, and 24.0%, respectively, did so in the placebo group (all P < 0.05). Both the PFS and MFS were significantly improved in patients younger than 50 years and those with free T3 ≥ 4.0 pg/mL by treatment with L-carnitine compared with placebo. Additionally, the MFS was significantly improved in patients taking thyroid hormone after thyroid cancer surgery. These results suggest that L-carnitine supplementation may be useful in alleviating fatigue symptoms in hypothyroid patients, especially in those younger than 50 years and those who have hypothyroidism after thyroidectomy for thyroid cancer (ClinicalTrials.gov: NCT01769157).

Abstract
Aging can result in major changes in the composition and metabolic activities of bacterial populations in the gastrointestinal system and result in impaired function of the immune system. We assessed the efficacy of prebiotic Darmocare Pre(®) (Bonusan Besloten Vennootschap (BV), Numansdorp, The Netherlands) to evaluate whether the regular intake of this product can improve frailty criteria, functional status and response of the immune system in elderly people affected by the frailty syndrome. The study was a placebo-controlled, randomized, double blind design in sixty older participants aged 65 and over. The prebiotic product was composed of a mixture of inulin plus fructooligosaccharides and was compared with placebo (maltodextrin). Participants were randomized to a parallel group intervention of 13 weeks' duration with a daily intake of Darmocare Pre(®) or placebo. Either prebiotic or placebo were administered after breakfast (between 9-10 a.m.) dissolved in a glass of water carefully stirred just before drinking. The primary outcome was to study the effect on frailty syndrome. The secondary outcomes were effect on functional and cognitive behavior and sleep quality. Moreover, we evaluated whether prebiotic administration alters blood parameters (haemogram and biochemical analysis). The overall rate of frailty was not significantly modified by Darmocare Pre(®) administration. Nevertheless, prebiotic administration compared with placebo significantly improved two frailty criteria, e.g., exhaustion and handgrip strength (p < 0.01 and p < 0.05, respectively). No significant effects were observed in functional and cognitive behavior or sleep quality. The use of novel therapeutic approaches influencing the gut microbiota-muscle-brain axis could be considered for treatment of the frailty syndrome.

[PMID: 25797079 DOI: 10.1016/j.physbeh.2015.03.023] [Citation(s) in RCA: 33] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/09/2014] [Revised: 12/13/2014] [Accepted: 03/18/2015] [Indexed: 12/29/2022]
Abstract
Nutrition and physical exercise can enhance cognitive function but the specific combinations of dietary bioactives that maximize pro-cognitive effects are not known nor are the contributing neurobiological mechanisms. Epigallocatechin-3-gallate (EGCG) is a flavonoid constituent of many plants with high levels found in green tea. EGCG has anti-inflammatory and anti-oxidant properties and is known to cross the blood brain barrier where it can affect brain chemistry and physiology. β-Alanine (B-ALA) is a naturally occurring β-amino acid that could increase cognitive functioning by increasing levels of exercise via increased capacity of skeletal muscle, by crossing the blood brain barrier and acting as a neurotransmitter, or by free radical scavenging in muscle and brain after conversion into carnosine. The objective of this study was to determine the effects of EGCG (~250mg/kg/day), B-ALA (~550mg/kg/day), and their combination with voluntary wheel running exercise on the following outcome measures: body composition, time to fatigue, production of new cells in the granule layer of the dentate gyrus of the hippocampus as a marker for neuronal plasticity, and behavioral performance on the contextual and cued fear conditioning tasks, as measures of associative learning and memory. Young adult male BALB/cJ mice approximately 2months old were randomized into 8 groups varying the nutritional supplement in their diet and access to running wheels over a 39day study period. Running increased food intake, decreased fat mass, increased time to exhaustive fatigue, increased numbers of new cells in the granule layer of the hippocampus, and enhanced retrieval of both contextual and cued fear memories. The diets had no effect on their own or in combination with exercise on any of the fitness, plasticity, and behavioral outcome measures other than B-ALA decreased percent body fat whereas EGCG increased lean body mass slightly. Results suggest that, in young adult BALB/cJ mice, a 39day treatment of exercise but not dietary supplementation with B-ALA or EGCG enhances measures of fitness, neuroplasticity and cognition.

The elimination/challenge diet. MINNESOTA MEDICINE 2012; 95:43-44. [PMID: 23346726] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Subscribe] [Scholar Register] [Indexed: 06/01/2023]
Abstract
Elimination diets can be both a diagnostic tool and a therapeutic intervention for people with a suspected food sensitivity or allergy. They are clinically relevant not only for patients with functional gastrointestinal disorders but also for those with conditions where symptoms are refractory and a diagnosis is elusive. Elimination diets can help a physician make a diagnosis or identify an underlying cause of symptoms. The physician and team treating the patient can then use that information to recommend appropriate dietary and lifestyle changes as well as judicious drug therapy. This article describes the elimination/challenge diet approach and explains the rationale for undertaking it.

Effect of dried-bonito broth on mental fatigue and mental task performance in subjects with a high fatigue score. Physiol Behav 2007; 92:957-62. [PMID: 17655888 DOI: 10.1016/j.physbeh.2007.07.002] [Citation(s) in RCA: 21] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/05/2007] [Revised: 05/30/2007] [Accepted: 07/03/2007] [Indexed: 10/23/2022]
Abstract
Dried-bonito broth is commonly employed as a soup and sauce base in Japanese cuisine and is considered to be a nutritional supplement that promotes recovery from fatigue. Previous human trials suggest that the ingestion of dried-bonito broth improves several mood states; however, its effect on fatigue has not yet been clarified. The aim of this study was to clarify the effects of daily ingestion of dried-bonito broth on fatigue and cognitive parameters by a placebo-controlled double blind crossover trial. Forty-eight subjects with fatigue symptoms ingested the dried-bonito broth or a placebo solution every day for 4 weeks. Mood states were evaluated by the Profile of Mood States (POMS), and mental task performance was evaluated by the Uchida-Kraepelin psychodiagnostic (UKP) test. Fatigue and total mood disturbance (TMD) scores on the POMS test decreased significantly during the dried-bonito broth ingestion (p<0.05), but did not change significantly during placebo ingestion. The change in vigor score during dried-bonito broth ingestion was significantly higher than that during placebo ingestion at 2 weeks (p<0.05). The results of the UKP test indicate that the numbers of both total answers and correct answers significantly increased during dried-bonito broth ingestion (p<0.05), while no significant changes were observed in the placebo ingestion. These results suggest that the daily ingestion of dried-bonito broth may improve the mood states, may reduce mental fatigue and may increase performance on a simple calculation task.

Safety, tolerability and symptom outcomes associated with L-carnitine supplementation in patients with cancer, fatigue, and carnitine deficiency: a phase I/II study. J Pain Symptom Manage 2006; 32:551-9. [PMID: 17157757 DOI: 10.1016/j.jpainsymman.2006.09.001] [Citation(s) in RCA: 46] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/27/2006] [Revised: 09/06/2006] [Accepted: 09/07/2006] [Indexed: 10/23/2022]
Abstract
Carnitine deficiency is among the many metabolic disturbances that may contribute to fatigue in patients with cancer. Administration of exogenous L-carnitine may hold promise as a treatment for this common symptom. Little is known about L-carnitine safety, tolerability, and dose-response in patients with cancer. We conducted a Phase I/II open-label trial to assess the safety and tolerability of exogenous L-carnitine and clarify the safe dose range associated with symptom effects for future controlled trials. Adult patients with advanced cancer, carnitine deficiency (free carnitine <35 for males or <25 microM/L for females, or acyl/free carnitine ratio >0.4), moderate to severe fatigue, and a Karnofsky Performance Status (KPS) score > or =50 were entered by groups of at least three into a standard maximum tolerated dose design. Each successive group received a higher dose of L-carnitine (250, 750, 1250, 1750, 2250, 2750, 3000 mg/day, respectively), administered in two daily doses for 7 days. To compare symptom outcomes before and after supplementation, patients completed validated measures of fatigue (Brief Fatigue Inventory [BFI]), depressed mood (Center for Epidemiologic Studies Depression Scale [CES-D]), quality of sleep (Epworth Sleeplessness Scale [ESS]), and KPS at baseline and 1 week later. Of the 38 patients screened for carnitine levels, 29 were deficient (76%). Twenty-seven patients participated ("intention to treat, ITT") (17 males, 10 females), and 21 completed the study ("completers"); 17 of these patients ("responders," mean+/-[SD] age=57.9+/-15) had increased carnitine levels at the end of the supplementation period. The highest dose achieved was 3000 mg/day. No patient experienced significant side effects and no toxicities were noted. Analysis of all the patients accrued (ITT, n=27) showed a total carnitine increase from 32.8+/-10 to 54.3+/-23 microM/L (P<0.001) and free carnitine increase from 26.8+/-8 to 44.1+/-17 microM/L (P<0.001). BFI decreased significantly, from 66+/-12 to 39.7+/-26 (P<0.001); ESS decreased from 12.9+/-12 to 9+/-6 (P=0.001); and CES-D decreased from 29.2+/-12 to 19+/-12 (P<0.001). A separate analysis of the 17 "responders" showed a dose-response relationship for total- (r=0.54, P=0.03), free-carnitine (r=0.56, P=0.02) levels, and fatigue (BFI) scores (r=-0.61, P=0.01). These findings suggest that l-carnitine may be safely administered at doses up to 3000 mg/day and that positive effects may be more likely at relatively higher doses in this range. This study provides the basis for the design of future placebo-controlled studies of l-carnitine supplementation for cancer-related fatigue.

The influence of underweight and dietary support on well-being in lung transplant candidates. Respir Med 2006; 100:1239-46.

Abstract
BACKGROUND Quality of life has been found to be a significant predictor of survival in lung transplantation candidates. The aim of this study was to investigate associations between underweight, dietary support and well-being. METHODS A self-administered questionnaire for perceived well-being was administered to underweight (n=42) and normal-weight (n=29) candidates for lung transplantation before and after dietary intervention in which the underweight patients received dietary support for weight gain. RESULTS Underweight compared with normal-weight, independent of lung function, was associated with low well-being in several of the measured dimensions. Improvements were observed after dietary intervention compared with baseline in the underweight patients, for scores in the dimension of tiredness 29.2 (4.2) vs. 26.2 (6.0), P<0.01; general satisfaction 4.7 (1.5) vs. 4.0 (1.4), P=0.01; social life 16.7 (3.9) vs. 15.0 (4.4), P=0.02) (mean (sd) before and after dietary intervention respectively), but not in the normal-weight patients. The underweight patients achieved the goal for energy intake and protein intake and experienced a significant weight gain. Regression analyses showed that none of the well-being improvements was associated with weight gain or change in body composition. However, an association between less tiredness and an increase in protein intake was indicated (b=-0.305, P=0.055). CONCLUSION Underweight compared with normal-weight was associated with more impaired quality of life in candidates for lung transplantation and some benefit from dietary support in terms of well-being was indicated.

Abstract
Several factors have been identified to cause peripheral fatigue during exercise, whereas the mechanisms behind central fatigue are less well known. Changes in the brain 5-hydroxytryptamine (5-HT) level is one factor that has been suggested to cause fatigue. The rate-limiting step in the synthesis of 5-HT is the transport of tryptophan across the blood-brain barrier. This transport is influenced by the fraction of tryptophan available for transport into the brain and the concentration of the other large neutral amino acids, including the BCAAs (leucine, isoleucine, and valine), which are transported via the same carrier system. Studies in human subjects have shown that the plasma ratio of free tryptophan (unbound to albumin)/BCAAs increases and that tryptophan is taken up by the brain during endurance exercise, suggesting that this may increase the synthesis of 5-HT in the brain. Ingestion of BCAAs increases their concentration in plasma. This may reduce the uptake of tryptophan by the brain and also 5-HT synthesis and thereby delay fatigue. Accordingly, when BCAAs were supplied to human subjects during a standardized cycle ergometer exercise their ratings of perceived exertion and mental fatigue were reduced, and, during a competitive 30-km cross-country race, their performance on different cognitive tests was improved after the race. In some situations the intake of BCAAs also improves physical performance. The results also suggest that ingestion of carbohydrates during exercise delays a possible effect of BCAAs on fatigue since the brain's uptake of tryptophan is reduced.

Abstract
Systemic syndromes characterized by a persistent activity of circulating mediators (cytokines) are frequently present with advanced cancer. We grouped under the general heading of "Systemic Immune-Metabolic Syndrome (SIMS)" a particular variety of distressing systemic syndrome characterized by dysregulation of the psycho-neuro-immune-endocrine homeostasis, with overlapping clinical manifestations. SIMS may include cachexia, anorexia, nausea, early satiety, fatigue, tumor fever, cognitive changes and superinfection. The aim of this study was to ameliorate some of the SIMS symptoms in a homogeneous group of lung adenocarcinoma patients using a multitargeted therapy. Fifteen patients with evidence of SIMS were studied. SIMS was defined as the presence of weight loss, anorexia, fatigue performance status>/=2 and acute-phase protein response. Patients received medroxyprogesterone (MPA) (500 mg twice daily), celecoxib (200 mg twice daily), plus oral food supplementation for 6 weeks. After treatment, 13 patients either had stable weight (+/- 1%) or had gained weight. There were significant differences in improvement of body-weight-change rate, nausea, early satiety, fatigue, appetite and performance status. Patients who had any kind of lung infection showed higher levels of IL-10 compared to non-infected patients (P=0.039). Our results suggest that patients with advanced lung adenocarcinoma, treated with MPA, celecoxib and dietary intervention, might have considerable improvement in certain SIMS outcomes. This multitargeted symptomatic approach deserves further study.

Abstract
OBJECTIVE To determine the subjective response to iron therapy in non-anaemic women with unexplained fatigue. DESIGN Double blind randomised placebo controlled trial. SETTING Academic primary care centre and eight general practices in western Switzerland. PARTICIPANTS 144 women aged 18 to 55, assigned to either oral ferrous sulphate (80 mg/day of elemental iron daily; n=75) or placebo (n=69) for four weeks. MAIN OUTCOME MEASURES Level of fatigue, measured by a 10 point visual analogue scale. RESULTS 136 (94%) women completed the study. Most had a low serum ferritin concentration; <or= 20 microg/l in 69 (51%) women. Mean age, haemoglobin concentration, serum ferritin concentration, level of fatigue, depression, and anxiety were similar in both groups at baseline. Both groups were also similar for compliance and dropout rates. The level of fatigue after one month decreased by -1.82/6.37 points (29%) in the iron group compared with -0.85/6.46 points (13%) in the placebo group (difference 0.95 points, 95% confidence interval 0.32 to 1.62; P=0.004). Subgroups analysis showed that only women with ferritin concentrations <or= 50 microg/l improved with oral supplementation. CONCLUSION Non-anaemic women with unexplained fatigue may benefit from iron supplementation. The effect may be restricted to women with low or borderline serum ferritin concentrations.

Abstract
BACKGROUND Postoperative fatigue is common, even after uncomplicated operations. Various theories have been presented regarding its aetiology, each suggesting different possible interventions. The purpose of this review was to identify all studies that have assessed interventions for postoperative fatigue and to evaluate these interventions using meta-analytical techniques. METHODS Randomized controlled trials of interventions, identified from a systematic search of relevant databases, were evaluated according to standardized criteria and categorized according to intervention modality. Data relating to the efficacy of each intervention at four different postoperative time-points were collated and data synthesis by meta-analysis was performed. RESULTS Analgesia is effective in reducing fatigue immediately after operation. Perioperative administration of human growth hormone reduces fatigue between 8 and 30 days after abdominal surgery. Weaker evidence was found to suggest an influence of glucocorticoid administration and of surgical technique on fatigue in the first week after operation. No evidence was found to support the theory that psychosocial or nutritional interventions affect the symptom. CONCLUSION While the results demonstrate that improved analgesia can attenuate immediate postoperative fatigue in most patient groups, further research is needed to determine whether the efficacy of human growth hormone and glucocorticoids extends beyond abdominal surgery. The paucity of research into cognitive-behavioural, sleep and activity-based interventions also needs to be addressed.

Commercial sport drinks versus light meal combat rations: effect on simulated combat maneuvers. Mil Med 2002; 167:692-7.

Abstract
This study compared a light meal combat ration (LMCR) to specific commercial sport drinks (CSD) and the effect of their ingestion on time to exhaustion during simulated combat maneuvers (SCM). The SCM consisted of three activities: a 2-hour march at 50% of maximal aerobic capacity (VO2max); a subsequent 1-hour run at 70% VO2max; and a run to exhaustion at 80% VO2max. During SCM, the subjects consumed one of four different meals: three CSD (Ergo, Go Sports, and Gatorlode), and the LMCR. In addition, one SCM was conducted with half-rations. Oxygen consumption, heart rate, and rating of perceived exertion were evaluated during each phase of the SCM. Time in minutes (mean +/- SD) to exhaustion at 80% VO2max for Ergo (42.3 +/- 8.9), Go Sports (39.4 +/- 13.3), and Gatorlode (37.7 +/- 8.6) was not significantly different from that for LMCR (36.4 +/- 13.0) but was greater than that for half-LMCR (30.3 +/- 9.3). O2 consumption, heart rate, and rating of perceived exertion were not affected by meal type but did increase over time for each stage of the SCM. We conclude that the amount of calories ingested was responsible for the differences noted in time to exhaustion. We further conclude that the CSD represent a readily available source of energy and fluid that could be used to replace and/or supplement the current LMCR.

Abstract
We investigated the antifatigue effect of royal jelly (RJ), which had been stored at -20 degrees C from immediately after collection, in male Std ddY mice. The mice were accustomed to swimming in an adjustable-current swimming pool, then subjected to forced swimming five times during 2 wk, and the total swimming period until exhaustion was measured. They were separated into three groups with equal swimming capacity, which were administered RJ, RJ stored at 40 degrees C for 7 d (40-7d RJ), or the control solution including casein, cornstarch, and soybean oil before swimming. All mice were forced to swim for 15 min once; then the maximum swimming time to fatigue was measured after a rest period. The swimming endurance of the RJ group significantly increased compared with those of the other groups. The mice in the RJ group showed significantly decreased accumulation of serum lactate and serum ammonia and decreased depletion of muscle glycogen after swimming compared with the other groups, whereas there was no significant difference between the 40-7d RJ group and the control group in these parameters after swimming. A quantitative analysis of constituents in RJ showed that 5 7-kDa protein, which we previously identified as a possible freshness marker of RJ, was specifically degraded in RJ stored at 40 degrees C for 7 d, whereas the contents of various vitamins, 10-hydroxy-2-decenoic acid, and other fatty acids in RJ were unchanged. These findings suggest that RJ can ameliorate the physical fatigue after exercise, and this antifatigue effect of RJ in mice seems to be associated with the freshness of RJ, possibly with the content of 5 7-kDa protein.

Abstract
The effect of a strict, low-salt, uncooked vegan diet rich in lactobacteria on symptoms in 18 fibromyalgia patients during and after a 3-month intervention period in an open, non-randomized controlled study was evaluated. As control 15 patients continued their omnivorous diet. The groups did not differ significantly from each other in the beginning of the study in any other parameters except in pain and urine sodium. The results revealed significant improvements in Visual analogue scale of pain (VAS) (p=0.005), joint stiffness (p=0.001), quality of sleep (p=0.0001), Health assessment questionnaire (HAQ) (p=0.031), General health questionnaire (GHQ) (p=0.021), and a rheumatologist's own questionnaire (p=0.038). The majority of patients were overweight to some extent at the beginning of the study and shifting to a vegan food caused a significant reduction in body mass index (BMI) (p=0.0001). Total serum cholesterol showed a statistically significant lowering (p=0.003). Urine sodium dropped to 1/3 of the beginning values (p=0.0001) indicating good diet compliance. It can be concluded that vegan diet had beneficial effects on fibromyalgia symptoms at least in the short run.

Abstract
Fatigue, which may well be the most common experience of patients with cancer, remains underappreciated by health care professionals. Perhaps one reason is that because of its complexity and many components, fatigue is not completely understood. Knowledge of fatigue models, such as the integrated Fatigue Model of Piper, can help dietitians identify potential causes of fatigue such as activity-rest patterns, and identification can lead dietitians to early intervention. Understanding cancer treatment factors, such as nausea and decreased participation in activities of daily living, that are believed to play a part in fatigue form another level on which dietitians can provide intervention. Through intervention, dietitians, working with patients and other members of the multidisciplinary team, may increase the understanding and appreciation of fatigue as well as provide relief from it. Efforts to maintain nutritional status can decrease or prevent some of the fatigue associated with cancer and its treatment. Therefore, the goal of clinical dietitians who work with a fatigued patient with cancer is to use nutrition management to minimize therapeutic side effects and maximize the patient's nutritional parameters.

Abstract
Seventeen patients undergoing elective open cholecystectomy were given conventional total parenteral nutrition either with (nine patients) or without (eight) glutamine supplementation of 20 g/day for 3 days after surgery and thereafter ordinary food for the following 27 days. Muscle protein synthesis, as assessed by the total concentration of ribosomes, decreased in control patients on day 3 following surgery and remained low on days 10, 20 and 30 (P < 0.05). In patients who received glutamine the total ribosome concentration was maintained on the third day after operation. Concurrently, the subjective feeling of fatigue increased on days 3 and 10 after surgery and the nitrogen balance was negative after operation in both groups, without any difference related to glutamine supplementation. Intravenous glutamine after surgery counteracts a decline in muscle protein synthesis only for as long as it is provided.
