Does Dietary Supplement Use Increase Micronutrient Intake Adequacy in Healthy Adults with Habitual Omnivorous, Vegetarian, Vegan, and Low-Carbohydrate High-Fat Diets?

Diets omitting whole food groups pose a risk for micronutrient insufficiencies, but there are no data as to whether those are suitably attenuated with dietary supplements (DS). Micronutrient intakes with food and DSs were analyzed in 130 healthy adults: 32 vegans, 37 vegetarians, 24 following low-carbohydrate high-fat diet (LCHF), and 37 omnivores. A total of 63% used DS (84% of vegans, 75% of LCHF, 54% of vegetarians, and 46% of omnivores); however, a DS did not always tackle dietary insufficiencies. Vitamin B12 was often supplemented in vegans in doses substantially higher than recommended, but it was supplemented less often in vegetarians, despite the low prevalence of sufficient intake. Only 43% of participants supplemented vitamin D in wintertime, 23% of them with an insufficient dose. Supplementation of potassium, calcium, and iodine was rare, despite low intake adequacy with food alone in all groups. Some micronutrients were supplemented unnecessarily, such as vitamin K, riboflavin, biotin, and iron. Multimicronutrient DSs were used often; they increased intake adequacy of group B vitamins but failed to sufficiently supplement vitamin D, potassium, calcium, and iodine. Although DS use increased micronutrient intake sufficiency when used properly, the knowledge on micronutrient inadequacy in all dietary patterns should be increased and the public should be educated on the proper use of DSs. Multimicronutrient DSs should be reformulated to tackle the insufficiencies.

Use of Dietary Supplements and Influencing Factors in Children.

In recent years, the use of dietary supplements has increased in all age groups. Parents may also use these supplements for their children for different reasons. This study aims to determine the use of dietary supplements by children, the factors affecting this use, and the attitudes of parents about these products. A total of 1038 children aged 2-18 years without any chronic disease who presented to the pediatric outpatient clinics of Ege University Children's Hospital were included in this study. Parents (n = 1000) who agreed to participate in the study were interviewed face-to-face, and a comprehensive questionnaire including questions about children's use of dietary supplements, sociodemographic characteristics, and parents' attitudes towards dietary supplements was administered. Analyses were performed with SPSS 25.0. The mean age of the children included in our study was 8.6 ± 4.8 years, and 51% (n = 510) were male. It was found that 32.5% of the children used nutritional supplements, and vitamin-mineral preparations (23.2%) were the most frequently used. Omega-3 (19.3%) and immune support products (9.4%) were the second and third most frequently used supplements, respectively. A significant relationship was found between the use of dietary supplements and the child's age, body weight, body mass index, parents' educational level, being health worker, and economic status (p < 0.05). It was found that most of the families thought that vitamin-mineral and omega-3 products were beneficial for growth and development and that they received information from doctors most frequently before taking these products. However, it was found that families followed the media as the second most frequent source of information for these products. Approximately one-third of the children in our study use dietary supplements. It is very important to raise awareness among families about the use of these products when necessary and with the recommendation of a physician. To prevent families from using dietary supplements that are not necessary for their children, especially due to misinformation in the media, pediatricians should provide correct information to parents about these products at every clinic visit. A concerted effort is needed from policy makers, media organizations, and health care providers to guide the safe use of DS. The results obtained from this study will shed light on future randomized controlled prospective studies.

Nutraceutical and dietary supplement use in the cancer population: The impact of evidence-based education.

10611 Background: The nutraceutical market is a multi-billion dollar industry. Studies show many cancer patients turn to vitamins and nutraceutical supplements, seeking health improvements post-diagnosis. Despite their popularity, the efficacy &amp; safety of most substances remains unverified through clinical trials. Additionally, interaction with cancer treatments could potentially increase toxicities or diminish chemotherapy effects. In response, our Cancer Center initiated a comprehensive program aimed at enhancing informed decision-making. This involved conducting surveys to understand patient’s attitudes, knowledge, and perceptions about supplement use, alongside evaluating the impact of an educational intervention designed to encourage the discontinuation of self-prescribed vitamins and supplements during cancer treatment. Methods: We utilized a structured survey with open-closed-ended questions to assess dietary supplement use among cancer patients. The survey featured multiple-choice and 1-5 Likert scale questions covering supplement types (e.g., vitamins, minerals, herbs), reasons for use, duration, and timing of use, and beliefs about safety &amp; efficacy. Clinicians also reviewed disclosed non-prescription supplements, advising on their continuation or cessation. Our goal was to understand patient perspectives on supplement use pre &amp; post-educational intervention, among new patients undergoing oral or systemic cancer treatment. We analyzed changes in supplement use with McNemar’s Exact Tests for paired proportions. Results: Following the educational intervention with 144 cancer patients, the proportion not using any supplements rose from 44.4% to 50.0%, hinting at a trend towards discontinuing supplement use. Yet, McNemar’s tests for various supplement categories revealed no statistically significant changes (p&gt;0.05). Of the 73 patients taking supplements and evaluated post-education by a physician, 53.4% were permitted to continue (primarily vitamins), 26% agreed to stop, and 20.5% reaffirmed they would not discontinue use. Of the resistant patients choosing to continue despite medical advice, 93.3% were taking high-dose vitamins, 20% minerals, and 13% herbs/botanical compounds. Conclusions: Supplements are heavily marketed as promoting various anticancer benefits. Our study shows the challenging nature of modifying cancer patients' perceptions. Despite a modest uptick in stopping, a significant portion persisted supplement use post-education, highlighting entrenched beliefs &amp; attitudes. This emphasizes the importance of ongoing, tailored discussions within oncology care to reduce the risks associated with unsupervised supplement use. Our results advocate for incorporating longer-term educational strategies about supplements, underscoring the critical need for evidence-based guidance in managing their use among cancer patients.

Nutraceuticals: New Perspective and Approach to Prevent Dysmenorrhea

Background: The words "nutrition" and "pharmaceutical" are combined to form the phrase "nutraceutical." Nutraceuticals are foods or dietary components that have an important role in regulating and sustaining normal physiological function in humans. For the treatment of dysmenorrhoea, a variety of pharmacological medications are available, however, they all have significant side effects. Dietary supplements and lifestyle management, on the other hand, were found to have a major influence on the occurrence and control of dysmenorrhea. Objective: The objective of this paper is to study a comprehensive review of the dietary and nutritional supplements with special emphasis on dysmenorrhea. This paper focuses on understanding and interpreting the details of menstrual pain and its effective nutritional diet that can be used as a treatment for avoiding menstrual discomfort. Methods: The selection of data has been done by studying a combination of various research and review papers from different databases like PubMed, NCBI, Science Direct, WHO, Cochrane Library, and Web of Science from the year 2000-2022. Results: Based on various papers and literature reviews, we have concluded about various dietary supplements and herbs that can be used to avoid pain during mensuration followed by its all-daily requirement of nutrition on different age groups and efficacy of treatments. Conclusion: According to current evidence, young women should be instructed in the proper use of dietary supplements, nutrition, and vitamins, as well as the inclusion of effective diet and lifestyle changes such as exercise and a well-balanced diet with adequate nutrition, as these are likely to reduce the negative effects of dysmenorrhea.

Association between dietary supplements and frailty: a cross-sectional study using national survey data in South Korea

We aimed to examine the association between the use of specific types of dietary supplements and frailty using cross-sectional, nationally representative survey data. Adults aged ≥50 years in the Korea National Health and Nutrition Examination Survey 2018–2020 were included. We calculated a 46-item frailty index to assess frailty. In total, 27,384 older adults were included (mean age: 62.47 years; median frailty index: 0.12). Among them, 72% used at least one dietary supplement. The prevalence of dietary supplement use was higher among women than among men and in participants with higher socioeconomic status. Compared to non-users, users of dietary supplements had a healthier diet and nutrient intake, and lower levels of frailty. After adjusting for socioeconomic and dietary factors, users of vitamin C, red ginseng or calcium were found to be significantly less frail. Our findings indicate promising results concerning dietary supplement intake in managing frailty among older Korean adults.

Prevalence of Dietary Modification and Supplement Use in Patients with Metastatic Renal Cell Carcinoma Receiving Systemic Therapy.

Many patients diagnosed with cancer adopt dietary changes and supplement use, and a growing body of evidence suggests that such modifications can affect outcomes to cancer therapy. We sought to assess the prevalence of these practices and the surrounding physician-patient dialogue among patients with metastatic renal cell carcinoma. An online survey was administered by Kidney Cancer Research Alliance (KCCure), interrogating dietary modification patterns, supplement usage, out-of-pocket expenditure related to supplements, and patients' views toward alternative medicine practices. Patients with metastatic renal cell carcinoma receiving combination therapy were actively solicited. In total, 289 unique responses were collected. The most common first-line treatments were nivolumab/ipilimumab (32.4%) and axitinib/pembrolizumab (13.1%). Within the cohort, 147 (50.9%) started using supplements following diagnosis of renal cell carcinoma; the most utilized supplements were probiotics, cannabidiol (CBD) oil/marijuana, and Vitamin C, reported by 70 (47.6%), 61 (41.4%), and 54 (36.7%), respectively. Dietary modifications following cancer diagnosis were reported by 101 (34.9%) respondents, of which 19.8% followed the Mediterranean diet and 18.8% adopted a ketogenic diet. Most respondents (71.3%) noted that they consistently report supplement usage to their physicians. A substantial proportion of patients with metastatic renal cell carcinoma utilize dietary modification and supplements as an adjunct to antineoplastic therapy. Considering the widespread adoption of these practices and the reported effects on cancer treatment, it is crucial for healthcare providers to engage in discussions with patients regarding supplement use.

Measuring the impact of dietary supplementation with citrus or cucumber extract on chicken gut microbiota using 16s rRNA gene sequencing

This study investigated the effects of dietary supplements, citrus (CTS) and cucumber (CMB), on the jejunum and cecum microbiota of 14- and 28-days old broiler chickens to evaluate their impact on the gut health and assess their role as alternatives to antibiotic growth promoters (ABGPs). 16SrRNA gene sequencing revealed the overall bacterial microbiota composition was significantly affected by the gut site (p?<?0.001) but not by either of the dietary supplements, CTS and CMB, at both 14 and 28 days of age. However, as a result of Linear discriminant analysis (LDA) effect size (LEfSE), CTS dietary supplements significantly increased the counts of Lactobacillus (p?<?0.01) and decreased the counts of Enterococcus (p?<?0.01) and Clostridium (p?<?0.05) in the jejunum, whereas the counts of Blautia were increased (p?<?0.01) and Enterococcus were decreased (p?<?0.05) in the cecum at both ages. Only minor CMB effects were identified in the cecum and non in the jejunum. The use of CTS dietary supplements has been shown to be associated to the reduction of potentially pathogenic bacteria (Enterococcus and Clostridium) and to the growth of beneficial bacteria (Lactobacillus and Blautia) which are known to have positive effects on chicken health in terms of nutrients absorption, stimulation and production of short chain fatty acids (SCFAs). Therefore, this study suggests that the use of a CTS supplemented diet could promote gut health while no clear advantages have been identified with the use of CMB as a dietary supplement.

Management of Fatigue in Adult Survivors of Cancer: ASCO-Society for Integrative Oncology Guideline Update.

To update the ASCO guideline on the management of cancer-related fatigue (CRF) in adult survivors of cancer. A multidisciplinary panel of medical oncology, geriatric oncology, internal medicine, psychology, psychiatry, exercise oncology, integrative medicine, behavioral oncology, nursing, and advocacy experts was convened. Guideline development involved a systematic literature review of randomized controlled trials (RCTs) published in 2013-2023. The evidence base consisted of 113 RCTs. Exercise, cognitive behavioral therapy (CBT), and mindfulness-based programs led to improvements in CRF both during and after the completion of cancer treatment. Tai chi, qigong, and American ginseng showed benefits during treatment, whereas yoga, acupressure, and moxibustion helped to manage CRF after completion of treatment. Use of other dietary supplements did not improve CRF during or after cancer treatment. In patients at the end of life, CBT and corticosteroids showed benefits. Certainty and quality of evidence were low to moderate for CRF management interventions. Clinicians should recommend exercise, CBT, mindfulness-based programs, and tai chi or qigong to reduce the severity of fatigue during cancer treatment. Psychoeducation and American ginseng may be recommended in adults undergoing cancer treatment. For survivors after completion of treatment, clinicians should recommend exercise, CBT, and mindfulness-based programs; in particular, CBT and mindfulness-based programs have shown efficacy for managing moderate to severe fatigue after treatment. Yoga, acupressure, and moxibustion may also be recommended. Patients at the end of life may be offered CBT and corticosteroids. Clinicians should not recommend L-carnitine, antidepressants, wakefulness agents, or routinely recommend psychostimulants to manage symptoms of CRF. There is insufficient evidence to make recommendations for or against other psychosocial, integrative, or pharmacological interventions for the management of fatigue.Additional information is available at www.asco.org/survivorship-guidelines.

Dietary supplement intake in women with breast cancer before and after diagnosis: results from the SUCCESS C trial

BackgroundThere is little evidence that dietary supplements are beneficial for patients with breast cancer; therefore, they are usually not recommended by treatment guidelines. The aim of the present analysis was to assess the prevalence of dietary supplement (DS) intake among women before and after a breast cancer diagnosis.MethodsParticipants in the SUCCESS C lifestyle intervention study, a randomized controlled trial in women with newly diagnosed intermediate- to high-risk breast cancer, completed two questionnaires on dietary supplement intake 24 months (QS1) and 48 months (QS2) after beginning the lifestyle intervention. The study was registered on 12.17.2008 under the EU Clinical Trials Register https://www.clinicaltrialsregister.eu/, trial registration number: 2008-005453-38. The questionnaires collected data on DS intake during the 5-year period prediagnosis (QS1) and in the period postdiagnosis (QS2). Multivariate logistic regression models were fitted to examine differences in DS intake between the two intervention groups. The groups were then pooled to examine differences in DS use between the prediagnostic and postdiagnostic period.ResultsA total of 320 questionnaires from 58.5% of intervention group completers and 416 questionnaires from 46.6% of low-level intervention group completers were included in the analysis. Overall, 20.2% of all respondents reported taking DS prior to their diagnosis. After a cancer diagnosis, the percentage of women taking DS significantly increased to 56.4% (p for time effect < 0.0001). No differences in DS intake between the intervention groups were observed. Single or combined preparations of vitamins and minerals/trace elements were the most frequently reported supplements. Notably, a 9-fold increase in vitamin D intake was reported postdiagnosis, where the proportion of women increased from 3.8 to 34.5%.ConclusionA 3-fold increase in the reported intake of dietary supplements was seen in women after a breast cancer diagnosis. These observations underscore the need to incorporate patient education surrounding the use of dietary supplements in a treatment care plan, particularly addressing the negligible benefits as well as the potential risks and treatment interactions.

Assessing β-Sitosterol Levels in Dietary Supplements for Benign Prostatic Hyperplasia: Implications for Therapeutic Efficacy.

Introduction Benign prostatic hyperplasia (BPH) is a prevalent condition among aging men that affects their life quality due to urinary symptoms. Current pharmacologic treatments, often lead to sexual dysfunction, so dietary supplements (DS) containing plant-based compounds such as β-sitosterol (SIT) are preferred. DSare highly accessible and widely used, but poorly regulated, so oftenpatients are victims of fraud. The use of DS to treat BPH symptoms is questionable, and this may be due not to the efficacity of the active compound but to the quality of commonly available DS. Aim This study aimed to assess the concentration of SIT in DS available on the market and evaluate whether the concentration of the active compound at the recommended dosage is sufficient to elicit beneficial effects in BPH. Method An HPLC-UV method based on direct saponification and acid hydrolysis was developed for the quantification of free and conjugated SIT in DS. The concentration of SIT in various DS was determined and compared with the one declared on the label. Results The chromatographic analysis confirmed the presence of SIT in all the DS but also showed a considerable variability of SIT content among DS, with only one product meeting the necessary concentration to bring potential benefits in BPH. Conclusion The study highlights inconsistencies in SIT content among DS and the importance of DS containing a standardized extract of SIT. Quality control measures are imperative to ensure that consumers receive effective and safe SIT-based DS to manage BPH symptoms. Further research is needed to establish standardized dosages and to evaluate their long-term efficacy and safety.

Adults with depressive symptoms have lower odds of dietary supplement use.

In this study, we aim to evaluate dietary supplement and complementary and alternative medicine (CAM) use in individuals with depressive symptoms. Furthermore, we conducted a comparative analysis of the usage of these agents among individuals with depressive symptoms, differentiating between those who were using antidepressants and those who were not. Additionally, we compared individuals with depressive symptoms who were not using antidepressants with participants who did not have depressive symptoms as well as individuals with depressive symptoms who were using antidepressants with individuals without depressive symptoms. The National Health and Nutrition Examination Survey 2007-2018 data was collected. Depressive symptoms were assessed using patient health questionnaire-9. Dietary supplement and antidepressants use was evaluated using Dietary Supplement Use and Prescription Medications Questionnaires. 31,445 participants, with 2870 (8.05%) having depressive symptoms were included. Participants with depressive symptoms had significantly lower odds of dietary supplement use compared with those without depressive symptoms (aOR = 0.827, 95% CI: 0.700,0.977, p = 0.026). Participants with depressive symptoms who were using antidepressants had significantly higher odds of dietary supplement (aOR = 1.290, 95% CI: 1.038,1.604, p = 0.022) compared with participants with depressive symptoms who were not using antidepressants. Furthermore, Participants with depressive symptoms who weren't using antidepressants had significantly lower odds of dietary supplement use (aOR = 0.762, 95% CI: 0.632,0.918, p = 0.005) compared with participants without depressive symptoms. In individuals with treated depressive symptoms compared to those without depressive symptoms, CAM use was significantly lower (aOR = 0.763, 95% CI = 0.598,0.973, p = 0.030). Individuals with depressive symptoms have lower odds of dietary supplement use. Further studies are needed to replicate these findings and examine the underlying mechanisms for this association.

Use of Dietary Supplements Among People With Atherosclerotic Cardiovascular Disease in the United States: A Population-Based Analysis From NHANES.

Dietary supplement use is prevalent in the general US population, but little is known regarding the driving reasons for their use among those with atherosclerotic cardiovascular disease (ASCVD). Data from the National Health and Nutrition Examination Survey (NHANES) from 2017 to March 2020 were used to identify adults with ASCVD. Supplement use was assessed by interviewers using label review, and surveys captured self-reported reasons for use. Demographic, clinical, medication, and laboratory characteristics were compared between supplement users and nonusers. Among individuals with ASCVD in the National Health and Nutrition Examination Survey (n=965; mean age, 65 years; 56.1% men; 73.7% White individuals), 73.1% reported taking ≥1 dietary supplements, most commonly multivitamins (35.4%), vitamin D (30.8%), and fish oil (19.8%). Of those taking supplements, 47.3% report taking them under the advisement of a health professional. Nearly one fifth (17.9%) reported taking at least 1 supplement for "heart health," most commonly fish oil (11.1%), followed by CoQ10 (4.2%) and resveratrol (1.5%). Supplement users were older (68 versus 62 years; P=0.003), included more women (45.8% versus 37.7%; P=0.17), were less likely to smoke (11.0% versus 36.4%; P<0.001), had higher levels of education (P=0.005) and income (P<0.001), and higher use of statins (69.4% versus 55.8%; P=0.046). Supplement use is common in people with ASCVD. Among the top 3 supplements, a substantial minority were being taken under the direction of health professionals. Supplement users often report taking supplements "for heart health," despite a lack of randomized trial evidence for benefit in ASCVD, indicating a need for more patient and clinician education regarding health benefits of dietary supplements in ASCVD.

Knowledge, attitudes, and practices of Lebanese patients with type II diabetes towards the use and abuse of dietary supplements: A cross-sectional study

Background Dietary supplements (DS) use among Lebanese patients with type 2 diabetes mellitus (T2DM) increased widely due to the country’s economic and financial situation. This study was conducted (1) to estimate the prevalence of DS use among persons with T2DM amid the escalating economic crisis in Lebanon; (2) to explore the knowledge, attitude, and practice (KAP) of DS use; and (3) to determine any significant association between socio-economic and socio-demographic factors and the use of DS modality Methods A cross-sectional study was conducted during the worst episode of the economic crisis between October and April 2022 on 460 adult patients with T2DM of both sexes. Patients were interviewed using a pre-tested questionnaire. Results Almost 4 out of 10 patients with T2DM in our study were found to be using DS, where 27.6% take multivitamins frequently. One-third of the participants agreed that nutritional supplements are necessary to control diabetes symptoms and complications. Around 41.1% of the participants complained about hypoglycemia and used DS to control their blood sugar levels (56.4%), while the rest used it to improve their health (35.5%) and control their diet (2.2%). The predictors of DS usage were the patient’s level of education [OR=3.9, CI=1.5-10, p=0.003), self-monitoring of blood sugars (OR=4.9, CI=1.68-14.6; p=0.004) and reading the nutrition label [OR=59.3, CI=6.3-55.8, p=0.000]. Conclusion This study estimated the prevalence of DS use and abuse, among persons with diabetes type II and found three significant predictors of DS use among patients with T2DM. Public health experts should encourage healthy discussions and awareness with their patients to comprehend their views regarding DS use.

Association between dietary supplement use and mortality in cancer survivors with different body mass index and frailty status: a cohort study.

The association between Body Mass Index (BMI), frailty index (FI), and dietary supplement in cancer survivors has been a subject of growing interest. This study investigates the relationship of BMI and FI with mortality in American cancer survivors and explores the impact of dietary supplement usage on different BMI and FI groups. Three thousand nine hundred and thirty-two cancer patients from the National Health and Nutrition Examination Survey (NHANES) database were included in the analyses. BMI, FI, and supplement usage were obtained through the NHANES structured survey and the 49-item FI tool. Weighted logistic and Cox proportional hazards models, Kaplan-Meier survival analyses, and propensity score matching (PSM) were used to elucidate the relationships between BMI, FI, dietary supplement, and mortality outcomes. The study found significant associations between higher BMI and increased frailty (Odds ratio [OR] = 1.04, 95% confidence interval [95% CI], 1.02-1.06). BMI < 25 kg/m2 and FI > 0.2 are associated with an increased mortality rate. Dietary supplement use can reduce all-cause and cancer mortality in cancer patients with BMI < 25 kg/m2 (Hazard ratio [HR] = 0.63, 95% CI, 0.47-0.84; HR = 0.48, 95% CI, 0.29-0.80) or FI ≤ 0.2 (HR = 0.77, 95% CI, 0.60-0.99; HR = 0.59, 95% CI, 0.39-0.89). In cancer patients with BMI < 25 kg/m2 and FI ≤ 0.2, dietary supplement users had lower all-cause and cancer mortality (HR = 0.49, 95% CI, 0.30-0.79; HR = 0.25, 95% CI, 0.10-0.60). The study revealed a negative correlation between BMI and the FI among the cancer patient cohort as well as their complex impact on mortality and highlighted the role of dietary supplement in cancer prognosis, indicating benefits for non-frail patients with BMI < 25 kg/m2.

Post-diagnosis dietary factors, supplement use and colorectal cancer prognosis: A Global Cancer Update Programme (CUP Global) systematic literature review and meta-analysis.

The role of diet in colorectal cancer prognosis is not well understood and specific lifestyle recommendations are lacking. We searched for randomised controlled trials (RCTs) and longitudinal observational studies on post-diagnosis dietary factors, supplement use and colorectal cancer survival outcomes in PubMed and Embase from inception until 28th February 2022. Random-effects dose-response meta-analyses were conducted when at least three studies had sufficient information. The evidence was interpreted and graded by the CUP Global independent Expert Committee on Cancer Survivorship and Expert Panel. Five RCTs and 35 observational studies were included (30,242 cases, over 8700 all-cause and 2100 colorectal cancer deaths, 3700 progression, recurrence, or disease-free events). Meta-analyses, including 3-10 observational studies each, were conducted for: whole grains, nuts/peanuts, red and processed meat, dairy products, sugary drinks, artificially sweetened beverages, coffee, alcohol, dietary glycaemic load/index, insulin load/index, marine omega-3 polyunsaturated fatty acids, supplemental calcium, circulating 25-hydroxyvitamin D (25[OH]D) and all-cause mortality; for alcohol, supplemental calcium, circulating 25(OH)D and colorectal cancer-specific mortality; and for circulating 25(OH)D and recurrence/disease-free survival. The overall evidence was graded as 'limited'. The inverse associations between healthy dietary and/or lifestyle patterns (including diets that comprised plant-based foods), whole grains, total, caffeinated, or decaffeinated coffee and all-cause mortality and the positive associations between unhealthy dietary patterns, sugary drinks and all-cause mortality provided 'limited-suggestive' evidence. All other exposure-outcome associations provided 'limited-no conclusion' evidence. Additional, well-conducted cohort studies and carefully designed RCTs are needed to develop specific lifestyle recommendations for colorectal cancer survivors.

Exploring dietary changes and supplement use among cancer patients in Norway: prevalence, motivations, disclosure, information, and perceived risks and benefits: a cross sectional study

BackgroundCancer is the leading cause of death in Norway, with prostate, breast, lung, and colon cancers being the most prevalent types. Adopting a healthy and varied diet can help reduce cancer risk and recurrence. However, access to dietary counselling remains limited for cancer patients in Norway. This study aimed to investigate the prevalence of dietary supplement use and dietary changes made by cancer patients and survivors. Additionally, it sought to explore the reason(s) for such practices, communication with healthcare providers, sources of information, and reported benefits and potential harms resulting from these changes and supplement use.MethodsConducted in collaboration with the Norwegian Cancer Society (NCS), this online cross-sectional study targeted members of their user panel who had either current or previous cancer (n = 706). The study took place in September/October 2021, utilizing a modified cancer-specific version of the International Questionnaire to Measure Use of Complementary and Alternative Medicine (I-CAM-Q). Out of 468 participants (315 women and 153 men), 67.2% consented to participate. Between-group analyses were conducted using Pearson chi-square tests and Fisher exact tests for categorical variables, while independent sample t-tests were applied for continuous variables.ResultsThe majority of the participants (97%) reported making changes to their diet (78%) and/or incorporating dietary supplements (73%) in response to their cancer diagnosis. The primary goal of these changes was to strengthen their body and immune system. Almost half of the participants (49%) reported that they found these changes beneficial and discussed them openly with their healthcare providers, with family physicians being the most common point of discussion (25%). Adverse effects were reported by only a few participants, mostly mild. Information about dietary changes and supplements was primarily sourced from the internet or healthcare providers.ConclusionsThis study highlights that most individuals affected by cancer attribute to dietary adjustment. It also emphasizes the importance of addressing adherence to dietary recommendations and using reliable sources of information. Additionally, the study highlights the potential, yet currently underutilized, role of healthcare professionals in initiating dialogues about dietary interventions to address any unmet needs of patients. Such proactive engagement may contribute to the promotion of reliable sources of information and the prevention of non-evidence-based and potentially harmful diets or supplement adoption.

Echinacea purpurea Polysaccharide Ameliorates Dextran Sulfate Sodium-Induced Colitis by Restoring the Intestinal Microbiota and Inhibiting the TLR4-NF-κB Axis.

Ulcerative colitis (UC) is a chronic intestinal ailment which cannot be completely cured. The occurrence of UC has been on the rise in recent years, which is highly detrimental to patients. The effectiveness of conventional drug treatment is limited. The long-term usage of these agents can lead to substantial adverse effects. Therefore, the development of a safe and efficient dietary supplement is important for the prevention of UC. Echinacea purpurea polysaccharide (EPP) is one of the main bioactive substances in Echinacea purpurea. EPP has many favorable effects, such as antioxidative, anti-inflammatory, and antitumor effects. However, whether EPP can prevent or alleviate UC is still unclear. This study aims to analyze the effect and mechanism of EPP on UC in mice using a 3% dextran sulfate sodium (DSS)-induced UC model. The results showed that dietary supplementation with 200 mg/kg EPP significantly alleviated the shortening of colon length, weight loss, and histopathological damage in DSS-induced colitis mice. Mechanistically, EPP significantly inhibits the activation of the TLR4/NF-κB pathway and preserves the intestinal mechanical barrier integrity by enhancing the expression of claudin-1, ZO-1, and occludin and reducing the loss of goblet cells. Additionally, 16S rRNA sequencing revealed that EPP intervention reduced the abundance of Bacteroides, Escherichia-Shigella, and Klebsiella; the abundance of Lactobacillus increased. The results of nontargeted metabonomics showed that EPP reshaped metabolism. In this study, we clarified the effect of EPP on UC, revealed the potential function of EPP, and supported the use of polysaccharide dietary supplements for UC prevention.

Efficacy of dietary supplements on mortality and clinical outcomes in adults with sepsis and septic shock: A systematic review and network meta-analysis

The aim of this network meta-analysis (NMA) was to investigate the effects of different dietary supplements on the mortality and clinical status of adults with sepsis. We searched PubMed, EMBASE, and the Cochrane Library Central Register of Controlled Trials until February 2023. The inclusion criteria were: 1) randomized controlled trials (RCT)s; 2) adults suffering sepsis or septic shock; 3) evaluation of short- or long-mortality; and 4) publications between 1994 and 2023. The general information of studies and details of interventions were extracted. The primary outcome was short-term mortality (<90 days), and the secondary outcomes were long-term mortality (≥90 days), length of ICU and hospital stays, and duration of mechanical ventilation (MV). The risk of bias of RCTs was assessed using the Cochrane risk of bias tool 2 (ROB2). A random effect NMA was performed to rank the effect of each intervention using a frequentist approach. Finally, 56 RCTs with 5957 participants met the criteria. Approximately, one-third of RCTs were low risk of bias. NMA analysis revealed that there was no treatment more effective in short- or long-term mortality than control or other interventions, except for magnesium (RR: 0.33, 95% CI: 0.14, 0.79; GRADE=low) and vitamin C (RR: 0.81, 95% CI: 0.67, 0.99; low certainty evidence), which had beneficial effects on short-term mortality. Moreover, eicosapentaenoic acid, gamma-linolenic acid, and antioxidants (EPA+GLA+AOs) combination was the most effective, and magnesium, vitamin D and vitamin C were the other effective approaches in terms of duration of MV, and ICU length of stay. There was no beneficial dietary supplement for hospital stay in these patients. In septic patients, none of the dietary supplements had a substantial effect on mortality except for magnesium and vitamin C, which were linked to lower short-term mortality with low certainty of evidence. Further investigation into high-quality studies with the use of dietary supplements for sepsis should be highly discouraged.

Prevalence of malnutrition, dietary trends, and oral nutritional supplements use among Algerian cancer outpatients undergoing chemotherapy

ObjectiveIt is widely acknowledged that patients with cancer commonly experience malnutrition, and some individuals may adopt specific dietary trends. This study investigated the prevalence of malnutrition and dietary trends among Algerian cancer outpatients undergoing chemotherapy. Material and methodsThis cross-sectional, descriptive study was conducted from January to October 2023 with 71 cancer outpatients undergoing chemotherapy. Malnutrition risk was evaluated using the Malnutrition Screening Tool (MST). The questionnaire also collected the occurrence of nutrition impact symptoms, the avoidance of specific food groups, and the use of oral nutritional supplements and dietary supplements. ResultsMalnutrition risk was identified in 57.7% (41 cases) of participants. Nutrition impact symptoms were reported by 59.2% (42 cases) of patients. A total of 36 of the patients (50.7%) altered their eating habits by avoiding at least one food group. Among malnourished cancer outpatients, only five used oral nutritional supplements. Dietary supplements were used by 23.9% (27/71) of the patients after cancer diagnosis. ConclusionOur findings underscore the necessity for a systematic malnutrition assessment in cancer patients. Qualified clinicians should provide nutritional awareness to enhance the quality of life for these patients.

Approaching the gateway to doping hypothesis through personality analysis

The relation between dark personality traits and fraudulent behaviour like doping in sports is empirically well established. However, the factors that lead athletes to start using illegal substances are less known. The gateway to doping hypothesis posits that widespread dietary supplement usage among athletes could potentially desensitise them, increasing the inclination towards doping use. To examine this hypothesis, the personality structure of athletes using dietary supplements for diverse motives is examined, aiming to identify patterns indicative of doping propensity, including dark traits, perfectionism, ego and task orientation and attitude towards doping. The final sample comprises 687 athletes (479 women; mean age = 26.06 ± 9.21 years). The findings suggest that the overall use and frequency of dietary supplement intake are not significantly predicted by personality traits indicative of a predisposition towards doping. While athletes that use supplements to enhance performance, regeneration, and body shape display a slightly more favourable attitude towards doping, dark traits exhibit an inverse link across all motives (except body shape enhancement) with substantial effect sizes. Although doping usage is not assessed in this study, the outcomes indicate that personality structures associated with doping do not predict dietary supplement use, thus challenging the gateway to doping hypothesis.
