There are numerous bioactive components, both nutritive and non-nutritive, in dietary supplements with considerable efficacy in promoting health. However, there are many ways disallowed ingredients may enter the supplement pipeline with potentially toxic effects. Dietary supplements can be regulated (either pre- or post-market) as a drug, dietary supplement, a nutraceutical, new dietary ingredient (NDI), generally recognized as safe (GRAS) food ingredient, a food additive, or a food. A pharmaceutical drug (medication) is used to treat, cure, prevent, or diagnose a disease and is regulated by the FDA pre-market only and allowed by medical prescription, whereas the other labeling designations are largely regulated post-market. One such molecule with a labeling problem is tianeptine, which has global use as an efficacious, prescribed drug, while at the same time being considered a non-drug and potentially dangerous adulterant often referred to as gas station heroin. In this paper, we critically evaluate the use and labeling of this compound and attempt to clarify the conundrum surrounding its legal or illegal use. Tianeptine is effective and efficacious as an antidepressant in those responding poorly to selective serotonin reuptake inhibitors (SSRIs) and exhibits many medicinal characteristics of tricyclic antidepressants with fewer opioid-like side effects. As a result, sixty-six countries permit use of tianeptine as a prescription drug. At higher doses, tianeptine has recently been shown to exhibit significant potential for abuse and dependency along with toxicity. As such, the US does not recognize tianeptine as an FDA-approved drug or as a dietary supplement, nutraceutical, new dietary ingredient (NDI), GRAS ingredient, or a food. Instead, tianeptine is a synthetic adulterant of a dietary supplement and considered technically an unapproved food additive. In conclusion, tianeptine, although viewed as a safe dietary supplement by many, is illegal in the US despite benefits to many but toxicity to others that make it vital that consumers and healthcare providers learn to critically evaluate and navigate the often confusing nomenclature of a purported dietary supplement to convey to the public whether it is efficacious, safe, and legal.展开更多

Forty-eight (48) Arabian sheep (45 non-pregnant females and 3 males for a sex ratio of 1 ram to 15 ewes) with an average weight of 20.3 ± 1.2 kg and aged approximately 2 years were divided into 3 groups of 15 ewes each. The supplemented group received in addition to the dominant forage of the pasture (300 g of Dactyloctenium aegyptium + 300 g of Cenchrus ciliaris + 600 g of Panicum maximum), 400 g and 600 g of Acacia albida leaves/animal/day while the control group received only 300 g of Dactyloctenium aegyptium + 300 g of Cenchrus ciliaris + 600 g of Panicum maximum. From the results of this study, it appears that the ewes that received 400 g of Acacia albida leaves had a significantly higher fertility rate and birth mortality rate (93.03% and 6.25% respectively). Animals in the control group had a significantly higher pre-weaning mortality rate than those receiving Acacia albida leaves as a supplement (16.66% versus 6.66% and 14.28% respectively). The highest weight of the lambs was observed in the ration supplemented with 600 g of Acacia albida leaves (12209.66 g). The total weight gain, as well as the average daily weight gain of the lambs receiving the 600 g Acacia albida leaf ration was significantly higher than those of the other rations. Supplementation with 400 g and 600 g of Acacia albida leaves can be recommended as a protein supplement for breeding ewes and pre-weaned lambs.展开更多

It is also one of the most prevalent complications of type 2 diabetes, prediabetes and metabolic syndrome. PN is commonly associated with pain, numbness, tingling, burning, and cramping in the feet and legs. Current treatment options are limited to controlling pain, seizures and use of antidepressant medications. These treatments have undesirable side effects and don’t stop PN progression. Here we utilized a combination of individual-specific modalities to improve local circulation and relieve PN symptoms. Methods: We conducted an open-label, multicenter pilot trial with 34 subjects (19 males and 15 females ranging from 40 - 85 years of age). All of the participants were diagnosed with peripheral neuropathy and had bilateral symptoms in their feet, and many reported the same symptoms (pain, numbness, tingling, burning, and cramping) in their lower legs. The duration of symptoms ranged from four months to over six years. On Day 0, subjects were given a 90-day supply of the oral supplement with dosing instructions and a LED light therapy device. They also received three platelet-rich plasma (PRP) injections in their lower extremities. Subjects also received an extracorporeal shockwave therapy (ESWT) treatment for each foot and subsequently twice per week for the first six weeks, then once weekly for the duration of the study. Subjects filled out the Brief Pain Index (BPI) at weekly intervals. On Day 90, subjects completed the Patient Global Impression of Change (PGIC) survey. Results: There were significant responses to pain, as evidenced by BPI scores at weeks 8, 9, 10 and 11 (p = 0.02, 0.01, 0.02, and 0.003, respectively). Analysis of the final day PGIC survey showed a favorable outcome for 73% of participants (p = 0.003), with the majority reporting Very Much Improved. Conclusions: By utilizing a multi-modality treatment protocol that includes PRP, LED light therapy, ESWT and an oral dietary supplement, we observed significant reductions in BPI scores. Quality of life and their overall impression of change (PGIC) were significantly improved, and there were no significant side effects.展开更多

These ONSs are designed to support the nutritional requirements of different age-groups, physiological states, or health conditions among Indian adults. Methods: The study had two phases viz., phase1 (n = 18) studied two ONSs: A1 and B1 and phase 2 (n = 20) studied five ONSs: A2, B2, C2, D2 & E2. The subjects were healthy, non-diabetic adults, aged between 20 - 44 years with a mean Body Mass Index of 21.2 ± 1.52 kg/m<sup>2</sup> (Phase 1) and 21.0 ± 1.45 kg/m<sup>2</sup> (Phase 2). All these ONSs were compared with reference drinks (glucose). The carbohydrates in one serving of each ONS were matched to carbohydrates from 25 grams of glucose following ISO 2010 guidelines. Capillary blood was assessed for blood glucose response at baseline, 15, 30, 45, 60, 90 and 120 minutes. GI was calculated as the incremental area under the curve (iAUC) for the test drinks and expressed as a percentage of the average iAUC from glucose. Results: Phase 1 indicated that the high fiber diabetes-specific nutrition supplement A1 with higher protein (23% energy), higher fat (25% energy) and reduced carbohydrates (40% energy) had a significantly (p = 0.002) lower GI [34 (±6)] as compared to B1 [63 (±7)] (protein 19%, fat 7% and carbohydrates 60% energy) even with similar amount (22%) and type of fiber. Phase 2 reported that all test products [A2 (32 ± 5), B2 (37 ± 4), C2 (31 ± 5), D2 (31 ± 5) and E2 (55 ± 4)] had a low GI. As compared to phase 1, ONSs in phase 2 had lower fiber content (1.6% - 4.6% energy). Conclusion: The glycemic index of oral nutrition supplements is influenced not only by their fiber content, but also by the overall macronutrient composition including protein (≥17% energy), fat (≥10% - 27% energy) and carbohydrates (40% - 57.5% energy).展开更多

Specifically, nutritional interventions may have an impact on the hypothalamic-pituitary axis resulting in positive health outcomes. A retrospective health status survey of 386 respondents was conducted to investigate the potential of a dietary supplement, Nutrifii<sup>TM</sup> Renew, for improving various health outcomes in comparison to a multivitamin/mineral control group. Among those who ingested Renew, 95% reported experiencing at least some improvement in one or more health categories. Compared to the multivitamin/mineral group, the Renew group reported earlier and/or greater improvements in several health status categories including sleep, reproductive health, memory, energy/stamina, skin and hair quality, flexibility, exercise recovery and feeling rested in the morning. A clear majority (84.9%) of Renew consumers reported experiencing noticeable improvement in some aspect of their health within one month. Among those who felt an improvement in sleep, most reported experiencing a change within one week. These improvements were likely due to the synergistic effects of L-arginine, L-citrulline, L-lysine, and botanical extracts on nitric oxide production, growth hormone (GH) release, and sleep quality. The observed improvements in skin elasticity and hair growth may be related to increased GH levels and IGF-1 production. Overall, these findings suggest that Renew may have potential as a dietary intervention for improving various health outcomes beyond those provided by multivitamin/mineral supplementation alone. Further studies are needed to confirm these findings and elucidate the underlying mechanisms of action.展开更多

Eighteen sows were fed 2 boluses per day of Saccharomyces cerevisiae var. boulardii CMCN-1079 (probiotic;PRO, n = 9) or placebo (CON, n = 9) starting at gestational day (GD) 84 and continuing until 21 days post-farrowing (end of lactation). Sow blood samples were collected every 7 days post-supplementation during gestation and 24-h post-farrowing and end of lactation. Blood samples were taken from 84 female pigs (n = 42 per sow treatment group) at 1, 7, 14, 21, 28, and 35 days old to assess innate and adaptive immune measures. Minimal effects of Scb supplementation were found on sow immune status during gestation and lactation, except for PRO-treated sows that had enhanced neutrophil function (P and mitogen-induced lymphocyte proliferation after 51 days of treatment (P < 0.0001). Overall, pigs from PRO-treated sows had higher C5a- and IL-8-induced neutrophil chemotaxis, NK cytotoxicity, and mitogen-induced B-lymphocyte proliferation than those from CON sows (P inimal effect on the sows but postnatal maternal exposure to Saccharomyces cerevisiae var. boulardii supplementation modulated the immune status of the progeny beyond the lactation period resulting in those from PRO-treated sows having more enhanced neutrophil function and B-cell proliferative response in the short term. Therefore, these data imply that including yeast probiotics in maternal diets may have carry-over effects in priming offspring’s immune function, especially neutrophil function and B-cell proliferation in the short term.展开更多

It is associated with an increased risk of low birth weight and prematurity and can contribute to impaired cognitive development in early childhood, as well as to maternal mortality. The impact on the fetus is even greater if maternal anemia onset is at an early stage, or prior to pregnancy. Iron salts, such as sulfate or fumarate, are widely used in the treatment of gravidic anemia, but due to various gastrointestinal side effects, many pregnant women are not compliant with treatment. Sodium iron EDTA, on the other hand, is highly absorbable and bioavailable. The latter improves hematological values and appears to be free from the usual iron-related side effects, hence compliance with this supplementation. Objectives: To evaluate the evolution of hemoglobin levels after sodium iron EDTA supplementation at the university Clinics of Kinshasa, to determine the frequency of gravidic anemia, the dose-dependent benefit of sodium iron EDTA supplementation in pregnant women and to identify factors associated with insufficient hemoglobin gain after supplementation. Methods: This longitudinal cohort will take place in the gynecology department of the University Clinics of Kinshasa from September 2022 to August 2023 and will include at least 54 pregnant women with anemia.

文摘Background This study investigated the effects of inorganic and organic minerals on physiological responses,oxidative stress reduction,and rumen microbiota in Holstein bull calves(123.81±9.76 kg;5 months old)during short-term heat stress(HS)and recovery periods.Eight Holstein calves were randomly assigned to four treatment groups:no mineral supplementation(Con),inorganic minerals(IM),organic minerals(OM),and high-concentration organic minerals(HOM)and two thermal environments(HS and recovery)using 4×2 factorial arrangement in a crossover design of four periods of 35 d.Calves were maintained in a temperature-controlled barn.The experimental period consisted of 14 d of HS,14 d of recovery condititon,and a 7-d washing period.Results Body temperature and respiration rate were higher in HS than in the recovery conditions(P<0.05).Selenium concentration in serum was high in the HOM-supplemented calves in both HS(90.38μg/dL)and recovery periods(102.00μg/dL)(P<0.05).During the HS period,the serum cortisol was 20.26 ng/mL in the HOM group,which was 5.60 ng/mL lower than in the control group(P<0.05).The total antioxidant status was the highest in the OM group(2.71 mmol Trolox equivalent/L),followed by the HOM group during HS,whereas it was highest in the HOM group(2.58 mmol Trolox equivalent/L)during the recovery period(P<0.05).Plasma malondialdehyde and HSP70 levels were decreased by HOM supplementation during the HS and recovery periods,whereas SOD and GPX levels were not significantly affected(P>0.05).The principal coordinate analysis represented that the overall rumen microbiota was not influenced by mineral supplementation;however,temperature-induced microbial structure shifts were indicated(PERMANOVA:P<0.05).At the phylum level,Firmicutes and Actinobacteria decreased,whereas Fibrobacteres,Spirochaetes,and Tenericutes increased(P<0.05),under HS conditions.The genus Treponema increased under HS conditions,while Christensenella was higher in recovery conditions(P<0.05).Conclusion HOM supplementation during HS reduced cortisol concentrations and increased total antioxidant status in Holstein bull calves,suggesting that high organic mineral supplementation may alleviate the adverse effects of HS.
文摘Malaria presents a significant global public health challenge,with severe malarial anaemia being a primary manifestation of the disease.The understanding of anaemia caused by malaria remains incomplete,making the treatment more complex.Iron is a crucial micronutrient essential for haemoglobin synthesis,oxygen delivery,and other vital metabolic functions in the body.It is indispensable for the growth of human beings,as well as bacteria,protozoa,and viruses in vitro and in vivo.Iron deficiency is among the most common nutritional deficiencies and can have detrimental effects during developmental stages of life.Malaria-induced iron deficiency occurs due to the hemolysis of erythrocytes and the suppression of erythropoiesis,leading to anaemia.Meeting iron requirements is particularly critical during pivotal life stages such as pregnancy,infancy,and childhood.Dietary intake alone may not suffice to meet adequate iron requirements,thus highlighting the vital role of iron supplementation.While iron supplementation can alleviate iron deficiency,it can exacerbate malaria infection by providing additional iron for the parasites.However,in the context of pregnancy and childhood,iron supplementation combined with malaria prevention and treatment has been shown to be beneficial in improving birth outcomes and ensuring proper growth and development,respectively.This review aims to identify the role and impact of iron supplementation in malaria infection during the life stages of pregnancy and childhood.

文摘Alzheimer’s disease(AD),the major form of neurodegenerative diseases that can severely impede normal cognitive function,makes it one of the most common fatal diseases.There are currently over 50 million AD patients worldwide.The neuropathology of AD is perplexing and there is a scarcity of disease-modifying treatments.Currently,early diagnosis of AD has been made possible with the discovery of biological markers associated with pathology,providing strong support for the improvement of the disease status.The search for inhibitors of AD markers from dietary supplements(DSs)has become a major hot topic.Especially with the widespread use of DSs,DSs containing polyphenols,alkaloids,terpenes,polysaccharides and other bioactive components can prevent AD by reducing Aβdeposition,inhibiting tau protein hyperphosphorylation,reconstructing synaptic dysfunction,weakening cholinesterase activity,regulating mitochondrial oxidative stress,neuronal inflammation and apoptosis.This review summarizes the anti-AD effects of the main DSs and their bioactive constituents,as well as the potential molecular mechanisms covers from 2017 to 2023.Additionally,we discussed the opportunities and challenges faced by DSs in the process of AD prevention and treatment,aiming to further provide new perspectives for functional food development.

文摘BACKGROUND The surge in traditional herbal dietary supplement(HDS)popularity has led to increased drug-induced liver injuries(DILI).Despite lacking evidence of efficacy and being prohibited from making medical claims,their acceptance has risen over sevenfold in the last two decades,with roughly 25%of United States(US)adults using these supplements monthly.An estimated 23000 emergency room visits annually in the US are linked to HDS side effects.NIH-funded research suggests HDS contribute to 7-20%of DILI cases,with similar trends in Europe—Spain reporting 2%and Iceland up to 16%.Patients with acute liver failure from HDS undergo liver transplantation more frequently than those from prescription medicines.Here we describe a case of drug-induced autoimmune hepatitis due to Skullcap supplements,this association appears to be the first documented instance in literature.CASE SUMMARY A middle-aged Caucasian woman,previously healthy,presented with sudden jaundice.Four months earlier,her liver enzymes were normal.She mentioned recent use of Skullcap mushroom supplements.Tests for chronic liver disease were negative.The first liver biopsy indicated severe resolving drug-induced liver injury.Despite treatment,she was readmitted due to worsening jaundice.Followup tests raised concerns about autoimmune hepatitis.A subsequent biopsy confirmed this diagnosis.The patient responded as expected to stopping the medication with improvement in liver enzymes.CONCLUSION This scenario highlights an uncommon instance of DILI caused by Skullcap supplements.It's crucial for hepatologists to recognize this connection due to the increasing prevalence of herbal supplements.

文摘Background Forage inclusion in starters of young dairy calves has become an acceptable strategy in the last decade.To compensate for the lower energy provided by forage,concurrent lipid supplementation can be proposed.How-ever,ruminal microbial activity and forage digestibility may be decreased by lipid supplementation.We hypothesized that the composite effect of forage and lipid supplements may be dependent on forage particle size and the type of lipid supplement.Therefore,we evaluated the effect of long(LP;geometric mean,4.97 mm)vs.short alfalfa hay particle sizes(SP;geometric mean,1.26 mm)with either soybean oil(SBO)or palm fatty acids(PLF)as lipid source in a 2×2 factorial design with treatments SP-SBO,SP-PLF,LP-SBO,and LP-PLF.Treatments(n=13 with 6 males and 7 females each)were offered to Holstein calves(3 days old)with equal amounts of lipid(25 g/kg DM)through-out the experimental period.The milk offering scheme(d 1 to 53)was equal for all groups.Data collection continued until 20 d post-weaning.Results Interaction between forage particle size and lipid supplement was significant for the following readouts:the highest and lowest starter intakes during the pre-weaning period occurred in LP-PLF and LP-SBO,respectively.This was associated with similarly contrasting changes in average daily gain(ADG)during the post-weaning period,body weight at the end of experiment,withers height,digestibility of organic matter and neutral detergent fiber,and blood serum concentrations of glucose,beta-hydroxybutyrate,and insulin during the pre-weaning period.Dur-ing both pre-and post-weaning periods,the highest and lowest urinary excretion of allantoin and total purine deriva-tives,representing microbial protein synthesis,were observed in LP-PLF and LP-SBO,respectively,indicating that those diets were most and least favorable for rumen development.Irrespective of forage particle size,supplemental SBO vs.PLF increased serum malondialdehyde as an oxidative stress indicator across periods,increased blood urea nitrogen and feed efficiency in the pre-weaning period,and reduced hip height during the post-weaning period.Conclusions It can be concluded that feeding a rumen-inert,mostly saturated fatty acid source with alfalfa hay as long particle size is recommended with view on performance,whereas a combination soybean oil rich in unsatu-rated fatty acids should not be provided to milk-fed Holstein calves together with long particle forage.Feeding soybean oil and alfalfa hay as long particles is not advisable mainly due to lower starter consumption and impaired development of ruminal function.If dietary supplementation of soybean oil is applied,incorporation of forage as small particles should be preferred to support rumen development.

文摘This present study was conducted to evaluate the metabolic effects of isolated fi ber of carrot supplementation in rats.Physicochemical properties of fi ber were determined.The groups were as follows:animals fed a standard diet,control group;high fi ber supplementation(70 mg);low fi ber supplementation(35 mg);for 12 weeks.Blood samples were collected at the time of sacrifi ce.The weights of heart,liver,kidneys and spleen of the experimental rats with respect to body weight were recorded.Commercial kits were used to determine serum glucose concentration,lipid profi le(cholesterol,HDL-cholesterol,triglycerides),and the two main aminotransferases glutamic-oxalacetic transaminase(GOT)/glutamate-pyruvate transaminase(GPT).A histopathological assay was performed on the heart,liver,and spleen tissues of animals.Supplementation with fi ber favors weight loss in female((242.03±23.73)-(197.81±10.45)g);and male rats((262.50±32.21)-(213.96±12.56)g and induces a decrease in glucose levels in the supplemented animals.With the exception of total high-density lipoprotein cholesterol,the other lipid fractions decrease signifi cantly in rats supplemented.Fiber supplementation did not induce changes in the dissected organs of the supplemented animals.In conclusion supplementation of fiber,improves glucose control,lower plasma lipid concentrations and reduced body weight in normal rats.
文摘Fodder production in arid rangelands has been traditionally considered as the main source of nutrition for livestock.However,the production of these fodder may be influenced by some socio-economic and climatic factors.This study aims to identify the various rangeland use forms and determine the types of livestock feeding system in the El Ouara rangelands of Ben guarden District in southern Tunisia by analysing the importance of supplemental feeding and main determinants of this practice.Data were collected by a survey that targeted a sample of 50 breeders in the El Ouara rangelands.Descriptive statistics and binary logistic regression were used to analyse the data.The results showed that there are two types of association practiced by breeders:“Cherka”association practiced by 10.00% of breeders and cash payment association practiced by 53.00% of breeders.Then,transhumance,sedentary,and semi-urban forms are the main ways in which breeders use the rangelands.There are four livestock feeding systems in the El Ouara rangelands being used to feed livestock:natural rangeland,rangeland-based,mixed,and concentrate-based feeding systems.Supplemental feeding has become fundamental for the livestock feeding system in the El Ouara rangelands.The breeders with the largest camel size still use the natural rangeland feeding system,while the breeders who have the largest herd size practice the mixed feeding system.The logistic regression results reveal that breeder age,cereal area,herd size,migrant remittance,second activity,and agricultural development group membership can significantly impact the supplemental feeding.In summary,this study can help policy-makers plan innovative practices based on climatic change,ensure the sustainability of livestock feeding system,and make effective decisions for local development.
文摘Dietary supplement sales have surpassed $30 billion per year with their use becoming and remaining extremely popular amongst the general public. There are numerous bioactive components, both nutritive and non-nutritive, in dietary supplements with considerable efficacy in promoting health. However, there are many ways disallowed ingredients may enter the supplement pipeline with potentially toxic effects. Dietary supplements can be regulated (either pre- or post-market) as a drug, dietary supplement, a nutraceutical, new dietary ingredient (NDI), generally recognized as safe (GRAS) food ingredient, a food additive, or a food. A pharmaceutical drug (medication) is used to treat, cure, prevent, or diagnose a disease and is regulated by the FDA pre-market only and allowed by medical prescription, whereas the other labeling designations are largely regulated post-market. One such molecule with a labeling problem is tianeptine, which has global use as an efficacious, prescribed drug, while at the same time being considered a non-drug and potentially dangerous adulterant often referred to as gas station heroin. In this paper, we critically evaluate the use and labeling of this compound and attempt to clarify the conundrum surrounding its legal or illegal use. Tianeptine is effective and efficacious as an antidepressant in those responding poorly to selective serotonin reuptake inhibitors (SSRIs) and exhibits many medicinal characteristics of tricyclic antidepressants with fewer opioid-like side effects. As a result, sixty-six countries permit use of tianeptine as a prescription drug. At higher doses, tianeptine has recently been shown to exhibit significant potential for abuse and dependency along with toxicity. As such, the US does not recognize tianeptine as an FDA-approved drug or as a dietary supplement, nutraceutical, new dietary ingredient (NDI), GRAS ingredient, or a food. Instead, tianeptine is a synthetic adulterant of a dietary supplement and considered technically an unapproved food additive. In conclusion, tianeptine, although viewed as a safe dietary supplement by many, is illegal in the US despite benefits to many but toxicity to others that make it vital that consumers and healthcare providers learn to critically evaluate and navigate the often confusing nomenclature of a purported dietary supplement to convey to the public whether it is efficacious, safe, and legal.
文摘Patients with celiac disease(CD)have a mucosal layer that is unable to regulate the gut microbiota,leaving the host vulnerable to dangerous infections and antigens.When compared to healthy people,this dysbiosis is marked by a decrease in intra-and intergeneric biodiversity,which demonstrates an imbalance between helpful bacteria and possibly harmful or proinflammatory species.The early gut microbiota is influenced by the genotype of newborns with the HLADQ2 haplotypes,and this may modify how gluten is handled in the intestinal lumen,polarize innate or adaptive immune responses,and result in glutensensitive enteropathy.The outcome of gluten digestion can vary depending on the composition of the intestinal gut bacteria and the partial conversion of gluten into peptides larger than ten amino acids in the small intestines,which can be immunogenic.In the small intestine,114 different bacterial strains belonging to 32 different species have 27 of them exhibiting peptidolytic activity.Thus,the individual risk of developing a gluten-related illness is further influenced by microbial composition and gluten degrading capacity.The conclusion that lactobacilli and Bifidobacterium spp.may be used as a probiotic supplement in CD patients is based on their shared possession of the most extensive peptidolytic and proteolytic activity thought to be engaged in the breakdown of gluten among all potential bacterial genera present in the gut microbiota.In children with CD autoimmunity,daily oral dose of Lactobacillus.plantarum HEAL9 and Lactobacillus.paracasei 8700:2 was found to modify the peripheral immune response.Bifidobacterium.breve strains have demonstrated a beneficial effect on reducing pro-inflammatory cytokine TNF-production in CD children on gluten-free diets.
文摘A trial on Acacia albida leaf supplementation on reproductive parameters and pre-weaning growth of Arabian lambs was conducted from September 2020 to May 2021 at the small ruminant station of the Livestock Research Institute for Development (IRED) in N’Djamena, Chad. Forty-eight (48) Arabian sheep (45 non-pregnant females and 3 males for a sex ratio of 1 ram to 15 ewes) with an average weight of 20.3 ± 1.2 kg and aged approximately 2 years were divided into 3 groups of 15 ewes each. The supplemented group received in addition to the dominant forage of the pasture (300 g of Dactyloctenium aegyptium + 300 g of Cenchrus ciliaris + 600 g of Panicum maximum), 400 g and 600 g of Acacia albida leaves/animal/day while the control group received only 300 g of Dactyloctenium aegyptium + 300 g of Cenchrus ciliaris + 600 g of Panicum maximum. From the results of this study, it appears that the ewes that received 400 g of Acacia albida leaves had a significantly higher fertility rate and birth mortality rate (93.03% and 6.25% respectively). Animals in the control group had a significantly higher pre-weaning mortality rate than those receiving Acacia albida leaves as a supplement (16.66% versus 6.66% and 14.28% respectively). The highest weight of the lambs was observed in the ration supplemented with 600 g of Acacia albida leaves (12209.66 g). The total weight gain, as well as the average daily weight gain of the lambs receiving the 600 g Acacia albida leaf ration was significantly higher than those of the other rations. Supplementation with 400 g and 600 g of Acacia albida leaves can be recommended as a protein supplement for breeding ewes and pre-weaned lambs.
文摘Objectives: Peripheral neuropathy (PN) is a significant contributor to disability in the elderly. It is also one of the most prevalent complications of type 2 diabetes, prediabetes and metabolic syndrome. PN is commonly associated with pain, numbness, tingling, burning, and cramping in the feet and legs. Current treatment options are limited to controlling pain, seizures and use of antidepressant medications. These treatments have undesirable side effects and don’t stop PN progression. Here we utilized a combination of individual-specific modalities to improve local circulation and relieve PN symptoms. Methods: We conducted an open-label, multicenter pilot trial with 34 subjects (19 males and 15 females ranging from 40 - 85 years of age). All of the participants were diagnosed with peripheral neuropathy and had bilateral symptoms in their feet, and many reported the same symptoms (pain, numbness, tingling, burning, and cramping) in their lower legs. The duration of symptoms ranged from four months to over six years. On Day 0, subjects were given a 90-day supply of the oral supplement with dosing instructions and a LED light therapy device. They also received three platelet-rich plasma (PRP) injections in their lower extremities. Subjects also received an extracorporeal shockwave therapy (ESWT) treatment for each foot and subsequently twice per week for the first six weeks, then once weekly for the duration of the study. Subjects filled out the Brief Pain Index (BPI) at weekly intervals. On Day 90, subjects completed the Patient Global Impression of Change (PGIC) survey. Results: There were significant responses to pain, as evidenced by BPI scores at weeks 8, 9, 10 and 11 (p = 0.02, 0.01, 0.02, and 0.003, respectively). Analysis of the final day PGIC survey showed a favorable outcome for 73% of participants (p = 0.003), with the majority reporting Very Much Improved. Conclusions: By utilizing a multi-modality treatment protocol that includes PRP, LED light therapy, ESWT and an oral dietary supplement, we observed significant reductions in BPI scores. Quality of life and their overall impression of change (PGIC) were significantly improved, and there were no significant side effects.
文摘Background: A randomized cross-over study was conducted to assess the glycemic index (GI) of seven Oral Nutritional Supplements (ONSs). These ONSs are designed to support the nutritional requirements of different age-groups, physiological states, or health conditions among Indian adults. Methods: The study had two phases viz., phase1 (n = 18) studied two ONSs: A1 and B1 and phase 2 (n = 20) studied five ONSs: A2, B2, C2, D2 & E2. The subjects were healthy, non-diabetic adults, aged between 20 - 44 years with a mean Body Mass Index of 21.2 ± 1.52 kg/m<sup>2</sup> (Phase 1) and 21.0 ± 1.45 kg/m<sup>2</sup> (Phase 2). All these ONSs were compared with reference drinks (glucose). The carbohydrates in one serving of each ONS were matched to carbohydrates from 25 grams of glucose following ISO 2010 guidelines. Capillary blood was assessed for blood glucose response at baseline, 15, 30, 45, 60, 90 and 120 minutes. GI was calculated as the incremental area under the curve (iAUC) for the test drinks and expressed as a percentage of the average iAUC from glucose. Results: Phase 1 indicated that the high fiber diabetes-specific nutrition supplement A1 with higher protein (23% energy), higher fat (25% energy) and reduced carbohydrates (40% energy) had a significantly (p = 0.002) lower GI [34 (±6)] as compared to B1 [63 (±7)] (protein 19%, fat 7% and carbohydrates 60% energy) even with similar amount (22%) and type of fiber. Phase 2 reported that all test products [A2 (32 ± 5), B2 (37 ± 4), C2 (31 ± 5), D2 (31 ± 5) and E2 (55 ± 4)] had a low GI. As compared to phase 1, ONSs in phase 2 had lower fiber content (1.6% - 4.6% energy). Conclusion: The glycemic index of oral nutrition supplements is influenced not only by their fiber content, but also by the overall macronutrient composition including protein (≥17% energy), fat (≥10% - 27% energy) and carbohydrates (40% - 57.5% energy).
文摘Dehydroepiandrosterone sulfate(DHEAS)is a hormone produced by the zona reticularis of the adrenal gland and the ovaries.Initially considered as an inert compound merely serving as an intermediate in the conversion of cholesterol to androgens,interest in DHEA began to grow in the 1960s when it was found that DHEAS is the most abundant steroid hormone in human plasma and that its levels decline with age.In many countries,DHEA is considered a nutritional supplement.It has been used for a multitude of conditions which include sexual dysfunction,infertility,genitourinary syndrome of menopause,musculoskeletal disorders,cardiovascular diseases,ageing,neurological diseases,autoimmune conditions,adrenal insufficiency,and anorexia nervosa.We describe an overview of the historical evolution of DHEA,its physiology,and the disease states where it has been evaluated as a supplement.
文摘Dietary factors play an important role in human health. Specifically, nutritional interventions may have an impact on the hypothalamic-pituitary axis resulting in positive health outcomes. A retrospective health status survey of 386 respondents was conducted to investigate the potential of a dietary supplement, Nutrifii<sup>TM</sup> Renew, for improving various health outcomes in comparison to a multivitamin/mineral control group. Among those who ingested Renew, 95% reported experiencing at least some improvement in one or more health categories. Compared to the multivitamin/mineral group, the Renew group reported earlier and/or greater improvements in several health status categories including sleep, reproductive health, memory, energy/stamina, skin and hair quality, flexibility, exercise recovery and feeling rested in the morning. A clear majority (84.9%) of Renew consumers reported experiencing noticeable improvement in some aspect of their health within one month. Among those who felt an improvement in sleep, most reported experiencing a change within one week. These improvements were likely due to the synergistic effects of L-arginine, L-citrulline, L-lysine, and botanical extracts on nitric oxide production, growth hormone (GH) release, and sleep quality. The observed improvements in skin elasticity and hair growth may be related to increased GH levels and IGF-1 production. Overall, these findings suggest that Renew may have potential as a dietary intervention for improving various health outcomes beyond those provided by multivitamin/mineral supplementation alone. Further studies are needed to confirm these findings and elucidate the underlying mechanisms of action.
文摘The primary objective of this study was to evaluate the potential immunomodulatory effect of maternal supplementation of Saccharomyces cerevisiae var. boulardii (Scb) from late gestation until the end of lactation on the immune phenotype of her progeny. Eighteen sows were fed 2 boluses per day of Saccharomyces cerevisiae var. boulardii CMCN-1079 (probiotic;PRO, n = 9) or placebo (CON, n = 9) starting at gestational day (GD) 84 and continuing until 21 days post-farrowing (end of lactation). Sow blood samples were collected every 7 days post-supplementation during gestation and 24-h post-farrowing and end of lactation. Blood samples were taken from 84 female pigs (n = 42 per sow treatment group) at 1, 7, 14, 21, 28, and 35 days old to assess innate and adaptive immune measures. Minimal effects of Scb supplementation were found on sow immune status during gestation and lactation, except for PRO-treated sows that had enhanced neutrophil function (P and mitogen-induced lymphocyte proliferation after 51 days of treatment (P < 0.0001). Overall, pigs from PRO-treated sows had higher C5a- and IL-8-induced neutrophil chemotaxis, NK cytotoxicity, and mitogen-induced B-lymphocyte proliferation than those from CON sows (P inimal effect on the sows but postnatal maternal exposure to Saccharomyces cerevisiae var. boulardii supplementation modulated the immune status of the progeny beyond the lactation period resulting in those from PRO-treated sows having more enhanced neutrophil function and B-cell proliferative response in the short term. Therefore, these data imply that including yeast probiotics in maternal diets may have carry-over effects in priming offspring’s immune function, especially neutrophil function and B-cell proliferation in the short term.
文摘Background: Anemia is mainly attributed to nutritional deficiency, especially iron deficiency, which predominates during pregnancy, and is associated with parasitic diseases such as malaria and intestinal parasitosis, acute or chronic diseases such as sickle cell disease, tuberculosis, HIV infection and various micronutrients disorders. It is associated with an increased risk of low birth weight and prematurity and can contribute to impaired cognitive development in early childhood, as well as to maternal mortality. The impact on the fetus is even greater if maternal anemia onset is at an early stage, or prior to pregnancy. Iron salts, such as sulfate or fumarate, are widely used in the treatment of gravidic anemia, but due to various gastrointestinal side effects, many pregnant women are not compliant with treatment. Sodium iron EDTA, on the other hand, is highly absorbable and bioavailable. The latter improves hematological values and appears to be free from the usual iron-related side effects, hence compliance with this supplementation. Objectives: To evaluate the evolution of hemoglobin levels after sodium iron EDTA supplementation at the university Clinics of Kinshasa, to determine the frequency of gravidic anemia, the dose-dependent benefit of sodium iron EDTA supplementation in pregnant women and to identify factors associated with insufficient hemoglobin gain after supplementation. Methods: This longitudinal cohort will take place in the gynecology department of the University Clinics of Kinshasa from September 2022 to August 2023 and will include at least 54 pregnant women with anemia. Conclusion: The study will enable us to better assess the benefits of sodium iron EDTA in improving hematological values, as well as its tolerability in pregnant women suffering from anemia during pregnancy in our environment.
文摘Background:Cucurbita maxima plant materials are frequently used to manage a number of disorders,according to previous studies.Objective:The goal of the present report was to look into further possible effects of this plant on kidney disorder in rats brought on by diabetes as well as the related abnormalities in lipid metabolism.Methods:To assess the ameliorative effect of the plant,streptozotocin(STZ)(45 mg/kg/day)was given as a single dosage to cause type 1 diabetes.After then,diabetic rats received supplemented diets of Cucurbita maxima for four weeks at 5%,10%,15%and 20%ad libidium.However,in another experiment to evaluate the preventive capacity of Cucurbita maxima,the STZ-induction came at the end of four weeks supplementation.Blood and kidney tissues were obtained at the end of the treatments and investigated.Consequently,the analysis of kidney function and lipid profile was made using serum obtained from the blood sample.Histological change in kidney was also observed using haematoxylin and eosin stain Results:Our findings demonstrated that Cucurbita maxima drastically(P<0.05)decreased the elevated kidney indicators such as urea and creatinine in the blood,and restored the electrolytes and lipid profiles anomalies as compared to the normal control.However,the alteration of biochemical parameters in the STZ-induced diabetic control remained unchanged throughout as compared to the normal control.The above mentioned biochemical changes that took place in kidney tissues were further corroborated by histological alterations.Conclusion:The results suggest that Cucurbita maxima leaves supplemented diets reversed STZ-induced renal disorder and abnormal lipid metabolism,and that these effects may be mediated by interacting with multiple receptors to raise the levels of antioxidant enzymes in the system.
文摘Background:Prenatal iron and folic acid supplementation is an economical strategy for reducing iron and folic acid deficiency anemia among expectant mothers in resource-limited countries like Uganda.This study aimed to assess the level of compliance with iron and folic acid supplementation(IFAS)and identify associated factors among mothers receiving prenatal services in Lira district,Uganda.Methods:A cross-sectional study was conducted at the antenatal clinic of Lira Regional Referral Hospital,involving 252 pregnant mothers.Adherence levels to IFAS were evaluated using a visual analogue scale,and associated factors were collected through an interviewer-administered questionnaire.The data were analyzed using SPSS software,and the results were presented in tables.Results:Only 46%of the mothers attending the antenatal clinic adhered to IFAS during the 30 days preceding the study.Participants who had good knowledge of IFAS before recruitment(odds ratio(OR)1.49,95%confidence interval(CI)1.12–1.97),utilized reminder techniques(OR 1.05,95%CI 1.02–1.09),and received support from their partners or relatives(OR 1.56,95%CI 1.07–2.29)were more likely to have good adherence.The main reasons for missing IFAS were forgetfulness and fear of taking too many tablets.Conclusions:There was a low adherence rate to IFAS among mothers attending antenatal clinics in Lira district.Further investigations are recommended to identify barriers to adherence,and comprehensive health education programs should be provided to pregnant mothers.
