Effect of educational intervention on knowledge and attitude about the role of vitamins, minerals and nutraceuticals in COVID-19 and other disorders among medical and nursing undergraduates of a tertiary care teaching hospital.

PURPOSE: There must be a perfect balance between Food and Dietary supplements (DS) to ensure optimal well-being. The purpose of this study was to evaluate the impact of a webinar on the change in knowledge and attitude about the role of vitamins, minerals and DS among medical and nursing undergraduates so that they could bring about a positive change in popular practices, as well-informed Health Care Professionals (HCPs). MATERIALS AND METHODS: The study was a cross-sectional analytical study comprising 12 knowledge and 11 attitude questions administered to medical and nursing undergraduates with the help of semi-structured and pre-validated google form both before and after a webinar explaining the role of key nutrients and also the evidence and recommendations surrounding DS. Data were analyzed using STATA.12 to assess the impact of the webinar. RESULTS: There were 415 participants, with 265 medical and 150 nursing students. There was a significant improvement both in the knowledge (4.95 (±1.45), 7.76 (±1.69) and attitude scores (pre-webinar mean score 31.8 (±5.57) post-webinar mean score 27.7 (±4.90))of the participants after the webinar. An overall positive correlation before the webinar changed to a more significant negative correlation, indicating a positive impact of the webinar (0.0054-0.0701). CONCLUSION: The study suggests that continuing education informing various HCPs and undergraduate students about the absolute necessity of a diet rich in nutrients, vitamins, minerals, and probiotics is the need of the hour. Additionally, the efficacy and safety concerns, appropriate indications and dosages of various DS should be adequately stressed so that informed decisions can be made. Such training programs might have a far-reaching impact on the nutrition choices of the population at large.

Assessment of the nutritional value and quality of diets offered in popular apps.

OBJECTIVE: People commonly use new technologies to promote a healthy lifestyle and help them lose weight through nutritional programs. This study evaluated the quality of individualized meal plans offered by dietary apps. MATERIALS AND METHODS: Ten apps that offer personalized meal plans were selected for the study, weekly meal plans were generated, and the nutritional values of the diets were calculated. The Healthy Diet Indicator and the Diet Quality Index were estimated. RESULTS: Significant differences between apps were observed in the calculated energy values (p<0.0001) and macronutrients (p<0.05), the content of vitamins (vitamin A, E, K, B1, B3, B6, folates, C: p<0.05) and minerals (potassium, calcium, phosphor, magnesium, iron, zinc, copper, manganese: p<0.05), as well as diet quality (p<0.05) and food group consumption (vegetables, fruits, grains, dairy products, vegan products, meat, nuts, fats, sweets, beverages: p<0.05). Most diets covered the demand for the required nutrients, but the percentage of energy from fats, proteins and carbohydrates differed from the recommendations. Moreover, the nutritional values of the diets provided in the apps significantly differ from the values calculated using the nutritional databases. CONCLUSIONS: The meal plans from apps significantly differ in nutrients and food group intake. The quality of the diets offered in the app should be improved.

Minerals and Antioxidant Micronutrients Levels and Clinical Outcome in Older Patients Hospitalized for COVID-19 during the First Wave of the Pandemic.

Excessive inflammatory response has been implicated in severe respiratory forms of coronavirus disease 2019 (COVID-19). Trace elements such as zinc, selenium, and copper are known to modulate inflammation and immunity. This study aimed to assess the relationships between antioxidant vitamins and mineral trace elements levels as well as COVID-19 severity in older adults hospitalized. In this observational retrospective cohort study, the levels of zinc, selenium, copper, vitamin A, ß-carotene, and vitamin E were measured in 94 patients within the first 15 days of hospitalization. The outcomes were in-hospital mortality secondary to COVID-19 or severe COVID-19. A logistic regression analysis was conducted to test whether the levels of vitamins and minerals were independently associated with severity. In this cohort (average age of 78 years), severe forms (46%) were associated with lower zinc (p = 0.012) and ß-carotene (p < 0.001) concentrations, and in-hospital mortality (15%) was associated with lower zinc (p = 0.009), selenium (p = 0.014), vitamin A (p = 0.001), and ß-carotene (p = 0.002) concentrations. In regression analysis, severe forms remained independently associated with lower zinc (aOR 2.13, p = 0.018) concentrations, and death was associated with lower vitamin A (aOR = 0.165, p = 0.021) concentrations. Low plasma concentrations of zinc and vitamin A were associated with poor prognosis in older people hospitalized with COVID-19.

Nutrition Guidelines for Improved Clinical Care.

Given the importance of poor nutrition as a cause for human chronic disease, it is surprising that nutrition receives so little attention during medical school training and in clinical practice. Specific vitamins, minerals, fatty acids, amino acids and water in the diet are essential for health, and deficiencies lead or contribute to many diseases. Proper use of the dietary guidelines and nutrition facts labeling can improve nutritional status and lead to the consumption of a healthy diet. COVID-19 has altered access to nutritious foods for millions and increased awareness of the importance of diet and immune function. An improved appreciation for nutrition will improve the outcomes of clinical care.

Evaluating a physicians' perspective on the use of probiotics and vitamins against coronavirus disease.

OBJECTIVE: To evaluate the perspective of family physicians on probiotics and vitamins against coronavirus disease-2019. METHODS: The cross-sectional study was conducted from June 1 to 30, 2021, after approval from the ethics review committee of Bursa Uludag University, Bursa, Turkey, and comprised family physicians of either gender working at family health centres in the country. Data was collected using an online questionnaire to measure the sociodemographic characteristics, habits, health status related to coronavirus disease-2019, and their knowledge, awareness and behaviour towards the use of probiotics and vitamins during the pandemic. Data was analysed using SPSS 25. RESULTS: Of the 218 family physicians, 130(59.6%) were male and 88(40.4%) were female. The overall mean age was 46.82±5.85 years, mean professional experience was 22.32±8.75 years, and mean experience in family medicine was 10.14±3.51 years. The knowledge and awareness level about coronavirus disease-2019 was high 4.18±0.58, exposure to the disease 3.36±0.83 and their inclination towards the use of vitamins and probiotics 1.68±0.75 was low. Among the participants, 90(41.3%) used probiotic products and 120(55%) used drugs, such as vitamins and minerals. Vitamin C 99(45.4%) was the most commonly used supplement. CONCLUSIONS: Physicians' knowledge and awareness and a realistic scientific approach are important when recommending supplements, such as probiotics, vitamins and minerals, to individuals during the pandemic.

Use of traditional and complementary medicine for COVID 19 prophylaxis among healthcare professionals and students in Jordan: A cross-sectional study.

INTRODUCTION: There is inadequate evidence to recommend the use of any traditional and complementary medicine (T&CM) methods such as vitamin, mineral, herbal or other dietary supplements to prevent or treat COVID 19. Members of the medical team are particularly at risk of exposure to high viral load of coronavirus. They have also the best access to professional information regarding disease treatment and prophylaxis and disseminate such knowledge. The aim of the study was to assess the prevalence of use of T&CM for the prophylaxis of COVID 19 among the healthcare professionals and students in Jordan, along with the most common types and the factors associated with T&CM use. METHODOLOGY: A cross-sectional study of T&CM use was conducted in Jordan using a snowball sampling method to distribute Google Forms and to enrol participants during coronavirus outbreak between June 10, 2021, and August 28, 2021. The study included healthcare professionals or students who consented to participate in the survey. The survey excluded those participants who had filled the questionnaire at least once or were pregnant/breast-feeding at the time of the study. The questionnaire consisted of 29 items, including screening, checkbox, dichotomous, matrix and open-ended questions. RESULTS: The response rate was 97.1%. Out of 560 study respondents, 359 (64.1%) reported using T&CM for COVID 19 prevention. Vitamins and nutrients were consumed by almost half (48.4%) of study participants, while nonpharmacological methods and herbal remedies were consumed by 35.2% and 25.2%, respectively. The most common source of information regarding T&CM use for COVID 19 prophylaxis included scientific publications (59.5%), followed by disease treatment guidelines (38.0%) and social media (32.3%). Adverse effects were reported by 8.5% and possible adverse effects were reported by another 8.5% of participants. The T&CM use was associated with working in contact with COVID 19 patients (OR: 1.625 (95% CI 1.047-2.523) (P = 0.03) and having a colleague as a source of information (OR: 1.720 (95% CI 1.026-2.883) (P = 0.04). CONCLUSIONS: The prevalence of T&CM use for COVID 19 prevention among healthcare professionals and students in Jordan is high, with a significant proportion of participants reporting adverse effects. There is an urgent need for further research toward efficacy and safety of T&CM in COVID 19 prophylaxis as well as development of appropriate public health policy on this issue specific to each country.

Large-scale staple food fortification as a complementary strategy to address vitamin and mineral vulnerabilities in India: A critical review.

The slow improvement in micronutrient malnutrition globally and in India warrants a need for scaling-up scientifically proven, cost-effective public health interventions. The present review discusses the potential of staple food fortification as a complementary strategy to tackle micronutrient deficiencies, while addressing the current concerns raised regarding its implementation. The review indicates the below par status of current strategies like dietary diversity and supplementation to address multiple micronutrients deficiencies in India and the need for complementary strategies to tackle this problem. Based on systematic reviews and meta-analysis, global and national evidence has identified staple food fortification as a proven and recognized cost-effective solution to address micronutrient deficiencies. The Government of India has shown a strong leadership to promote this proven intervention. Further, the paper addresses the concern that large-scale staple food fortification (LSFF) may lead to excessive nutrient intakes when delivered together with other interventions, e.g., supplementation, dietary diversity, among the same populations. A key message that emerges from this review is that LSFF is safe with current dietary intake and deficiencies and low coverage of other interventions. Given the current situation of food and nutrition insecurity which the COVID-19 pandemic has further exacerbated, and the critical role that nutrition plays in building immunity, it is even more important that health and nutrition of the population, especially vulnerable age groups, is not only safeguarded but also strengthened. LSFF should be implemented without any further delay to reach the most vulnerable segments of the population to reduce the dietary nutrient gap and prevent micronutrient deficiencies. Effective monitoring and regular dietary surveys will help ensure these interventions are being deployed correctly.

Coronal dentin differs between young and mature adult humans: A systematic review.

OBJECTIVE: This systematic review examines the effect of age on changes to coronal dentin properties. DESIGN: Pubmed, Cinhal, Scopus, Web of Science and the Cochrane Database were searched for publications up to 31 December 2021. All studies were uploaded and reviewed using Covidence software. At different stages of the review, study selection and the extraction of data were completed by six independent reviewers based on the eligibility criteria. The quality of the articles was judged based on JBI Critical Appraisal Checklist for quasi-experimental studies. RESULTS: Twelve studies satisfied the eligibility criteria and were included. Dentin characteristics and mechanical properties alter with age, and spatially within a tooth to depend on tubule orientation. Age-related mineral deposition within tubules, and collagen maturation in intertubular dentin compound the spatial effects on mechanical properties. Mechanical properties depend on collagen fiber orientation and apatite alignment relative to dentin tubules, characteristic differences in peritubular and intertubular dentin, and relative dentin tubule distribution within a tooth. The bulk of the research focussed on age-related apatite effects, although many reported limited understanding of changes to collagen, particularly in intertubular dentin. CONCLUSION: Investigations into the effect of age, depth, site and location on dentin collagen are warranted to minimize tooth loss in older populations by providing targeted adhesive, restorative or preventative interventions.

Reducing disease and death from Artisanal and Small-Scale Mining (ASM) - the urgent need for responsible mining in the context of growing global demand for minerals and metals for climate change mitigation.

Artisanal and small-scale mining (ASM) takes place under extreme conditions with a lack of occupational health and safety. As the demand for metals is increasing due in part to their extensive use in 'green technologies' for climate change mitigation, the negative environmental and occupational consequences of mining practices are disproportionately felt in low- and middle-income countries. The Collegium Ramazzini statement on ASM presents updated information on its neglected health hazards that include multiple toxic hazards, most notably mercury, lead, cyanide, arsenic, cadmium, and cobalt, as well as physical hazards, most notably airborne dust and noise, and the high risk of infectious diseases. These hazards affect both miners and mining communities as working and living spaces are rarely separated. The impact on children and women is often severe, including hazardous exposures during the child-bearing age and pregnancies, and the risk of child labor. We suggest strategies for the mitigation of these hazards and classify those according to primordial, primary, secondary, and tertiary prevention. Further, we identify knowledge gaps and issue recommendations for international, national, and local governments, metal purchasers, and employers are given. With this statement, the Collegium Ramazzini calls for the extension of efforts to minimize all hazards that confront ASM miners and their families.

Effectiveness of Different Methods in Removing Dentin Caries of Primary Teeth: Micro-CT and SEM Evaluation.

OBJECTIVES: With the recent improvements in technology, the expectation of minimal invasion and maximal comfort in caries removal techniques is increasing. This study aims to examine the effectiveness of six caries removal methods in primary teeth. STUDY DESIGN: Sixty primary molars (10 teeth in each groups) were used. The groups were: Group I (Tungsten Carbide Bur), Group II (Sono abrasion), Group III (Air abrasion), Group IV (Carisolv), Group V (Er:YAG Laser), Group VI (ART). In micro-CT scanning, mineral density at the cavity floor was examined before and after caries removal. After caries removal, the patency of the dentinal tubules was examined in two teeth from each group on SEM images. Statistical analyses were performed using Kruskal-Wallis, Wilcoxon tests. RESULTS: For six different caries removal methods, tooth mineral (inorganic, total) densities at cavity floors were compared among the groups after the procedures, and no statistically significant difference was found (p>0.05). On the SEM images, it was seen that the dentinal tubules were exposed and no smear layer was formed in the Carisolv group. Significant rough surfaces were exposed in the laser group. CONCLUSION: It was observed that alternative caries removal methods are at least as effective as the traditional method in primary teeth for clinical applications.

Molecular mechanisms and therapeutic effects of different vitamins and minerals in COVID-19 patients.

COVID-19 is a rapidly spreading disease, which has caught the world by surprise. Millions of people suffer from illness, and the mortality rates are dramatically high. Currently, there is no specific and immediate treatment for this disease. Remedies are limited to supportive regiments and few antiviral and anti-inflammatory drugs. The lack of a definite cure for COVID-19 is the reason behind its high mortality and global prevalence. COVID-19 can lead to a critical illness with severe respiratory distress and cytokine release. Increased oxidative stress and excessive production of inflammatory cytokines are vital components of severe COVID-19. Micronutrients, metalloids, and vitamins such as iron, manganese, selenium, Zinc, Copper, vitamin A, B family, and C are among the essential and trace elements that play a pivotal role in human nutrition and health. They participate in metabolic processes that lead to energy production. In addition, they support immune functions and act as antioxidants. Therefore, maintaining an optimal level of micronutrients intake, particularly those with antioxidant activities, is essential to fight against oxidative stress, modulate inflammation, and boost the immune system. Therefore, these factors could play a crucial role in COVID-19 prevention and treatment. In this review, we aimed to summarize antiviral properties of different vitamins and minerals. Moreover, we will investigate the correlation between them and their effects in COVID-19 patients.

The Perception of Minerals and Their Prevalence in Fortified Foods and Supplements in Japan.

People's intake of some minerals does not meet the nutrient reference values even in high-income countries. Recently, the deficiency of zinc and/or selenium has been considered to cause greater risk of COVID-19 infection and severity. To investigate consumer awareness, we conducted a cross-sectional questionnaire online survey among Japanese people (7500 males and 7500 females) concerning their perceptions of each mineral and the prevalence of mineral-fortified foods and/or mineral supplements. People's perception of each mineral varied: the highest was for calcium (91.8%) and the lowest was for selenium (44.7%). In addition, only a portion of participants believed that they consumed a sufficient amount of each mineral; the highest was sodium (23.7%), and the lowest was manganese (5.2%). In addition, 18.2% of them felt that they could not consume enough sodium, even though most of the Japanese's intake is excessive. Among mineral-fortified-food and/or mineral-supplement users, the purposes for these products were to maintain health (80.6%), supplement nutrients (48.0%), and prevent infectious diseases (23.2%). Only 18.4% of participants knew what amount they took. In conclusion, education is needed to prevent not only the insufficiency/deficiency of each mineral but also an excess intake of sodium.

Growth performance, carcass and meat quality, bone strength, and immune response of broilers fed low-calcium diets supplemented with marine mineral complex and phytase.

Influence of marine mineral complex (CeltiCal) as a partial substitute for limestone on growth efficiency, carcass traits, meat quality, bone strength, calcium (Ca) retention, and immune response was investigated in broilers fed low-Ca diets with or without phytase (PHY) addition for a 35-d trial period. A total of 300 one-day-old Ross 308 straight-run broilers were randomly allocated to: T1 (positive control), recommended Ca levels + PHY; T2 (negative control), 0.2% below the recommended Ca levels + PHY; T3, 0.1% below the recommended Ca levels + 0.2% CeltiCal + PHY; T4, 0.2% below the recommended Ca levels + 0.4% CeltiCal + PHY; T5, 0.2% below the recommended Ca levels + 0.4% CeltiCal. PHY was added at 500 phytase units/kg diets. Each dietary treatment had 10 replications of 6 chicks each. Results revealed that production efficiency factor was greater for T4 compared to T2 and T5 during 22-35 d and for T1, T3, and T4 compared to T2 during 0 to 35 d (P < 0.05). Feed conversion ratio was lower for T3 and T4 compared to T2 and T5 during 0 to 35 d (P < 0.05). T4 had a greater (P < 0.05) dressing percentage than T2, which had a lighter (P < 0.01) small intestinal relative weight than all other treatments. Breast meat temperature at 15 min postmortem was highest for T1 and lowest for T3 (P < 0.001). Breast meat pH was greater for T1 compared to T5 at 15 min postmortem and for T3 compared to T4 at 24 h postmortem (P < 0.05). T5 had a lower breast meat redness than all other treatments at 15 min postmortem and then T1 and T3 at 24 h postmortem (P < 0.01). Tibia and femur weights were greater (P < 0.05) for T3, T4, and T5 compared to T2, which had the lowest tibia ash content (P < 0.05) and femur geometric properties (P < 0.001). Greater antibodies to infectious bronchitis virus (P < 0.01) and Ca retention (P < 0.001) were observed for T3 and T4 in comparison to T2. Based on the findings of this research, CeltiCal can adequately replace a considerable portion of limestone in broiler reduced-Ca diets containing PHY.

Vitamins and minerals: A means for surviving the COVID-19 pandemic or just a myth?

A novel coronavirus (severe acute respiratory syndrome coronavirus 2 [SARS-CoV-2]) that was initially reported from Wuhan, China in December 2019, was declared a pandemic by the WHO in March 2020. Considering the current COVID-19 pandemic, where there are no specific effective preventive or therapeutic drugs available, a healthy immune system is one of the most important tools that should be considered. Vitamins and minerals supplements have been well known to help the immune system in battling viral infections in general. Physicians worldwide are largely interested in vitamin and mineral supplements to help them battle COVID-19 whether through protection or treatment. Dietary supplementations especially vitamin D, vitamin C, and Zinc offer good prophylactic and therapeutic support to the currently available treatment regimens. They are relatively safe and were proven to aid recovery in other respiratory infections. Further studies should be encouraged especially those examining their role in prophylaxis from COVID-19 while maintaining current recommendations for social distancing and proper protective gear.

Micronutrients for Attention-Deficit/Hyperactivity Disorder in Youths: A Placebo-Controlled Randomized Clinical Trial.

OBJECTIVE: To evaluate whether micronutrients (vitamins/minerals) benefit attention-deficit/hyperactivity disorder (ADHD) and irritability in a North American pediatric sample. METHOD: A 3-site, 8-week, placebo-controlled, randomized clinical trial of micronutrients was conducted in nonmedicated children aged 6 to 12 years with ADHD and at least 1 impairing irritability symptom by parent report on the Child and Adolescent Symptom Inventory-5 (CASI-5). A priori-defined primary outcomes were Clinical Global Impression-Improvement (CGI-I) (CGI-I of 1 or 2 = treatment responder) and parent-rated CASI-5 composite score of ADHD, oppositional defiant, disruptive mood dysregulation, and peer conflict symptoms, including impairment scores. RESULTS: Of 135 randomized (mean age 9.8 years), 126 youths (93%) comprised the modified intention-to-treat population. Blinding was maintained. For the CGI-I, 54% of the micronutrient and 18% of the placebo group were responders (risk ratio = 2.97, 97.5% CI = 1.50, 5.90, p < .001). CASI-5 composite scores improved significantly for both groups (p < .01), with a mean change of -0.31 (95% CI = -0.39, -0.23) in the micronutrient group and a mean change of -0.28 (95% CI = -0.38, -0.19) in the placebo group. However, the between-group difference was not significant (mean change = -0.02; 97.5% CI = -0.16, 0.12, effect size = 0.07, p = .70). The micronutrient group grew 6 mm more than the placebo group (p = .002). No serious adverse events or clinically significant changes from baseline in blood and urine tests occurred. CONCLUSION: Micronutrients showed global benefit over placebo by blinded clinician rating, but not by parent-report CASI-5 composite rating in a population with ADHD and irritability. Micronutrients showed greater height growth. Micronutrients were well tolerated, and the majority of participants adhered to the number of capsules prescribed. This randomized controlled trial replicates safety and efficacy reported for ADHD in 2 smaller trials of a similar formula containing all vitamins and known essential minerals in amounts between the Recommended Dietary Allowance and Upper Tolerable Intake Level. CLINICAL TRIAL REGISTRATION INFORMATION: Micronutrients for ADHD in Youth (MADDY) Study; https://clinicaltrials.gov; NCT03252522.

Associations of Habitual Mineral Intake with New-Onset Prediabetes/Diabetes after Acute Pancreatitis.

Associations between habitual dietary intake of minerals and glucose metabolism have been extensively studied in relation to metabolic disorders. However, similar research has yet to be conducted in individuals after acute pancreatitis (AP). The main aim was to investigate the associations between habitual intake of 13 minerals and glycaemic status: new-onset prediabetes/diabetes after AP (NODAP), pre-existing prediabetes/type 2 diabetes (T2DM), and normoglycaemia after AP (NAP). Associations between the dietary intake of minerals and markers of glucose metabolism (glycated haemoglobin and fasting plasma glucose) were also studied. The EPIC-Norfolk food frequency questionnaire was used in a cross-sectional fashion to determine the habitual intake of 13 dietary minerals. ANCOVA as well as multiple linear regression analyses were conducted and five statistical models were built to adjust for covariates. The study included 106 individuals after AP. In the NODAP group, intake of 4 minerals was significantly less when compared with the NAP group: iron (B = -0.076, p = 0.013), nitrogen (B = -0.066, p = 0.003), phosphorous (B = -0.046, p = 0.006), and zinc (B = -0.078, p = 0.001). Glycated haemoglobin was significantly associated with iodine intake (B = 17.763, p = 0.032) and manganese intake (B = -17.147, p = 0.003) in the NODAP group. Fasting plasma glucose was significantly associated with manganese intake (B = -2.436, p = 0.027) in the NODAP group. Habitual intake of minerals differs between individuals with NODAP, T2DM, and NAP. Prospective longitudinal studies and randomised controlled trials are now warranted to further investigate the associations between mineral intake and NODAP.

Dietary supplements, vitamins and minerals as potential interventions against viruses: Perspectives for COVID-19.

The novel coronavirus (SARS-CoV-2) causing COVID-19 disease pandemic has infected millions of people and caused more than thousands of deaths in many countries across the world. The number of infected cases is increasing day by day. Unfortunately, we do not have a vaccine and specific treatment for it. Along with the protective measures, respiratory and/or circulatory supports and some antiviral and retroviral drugs have been used against SARS-CoV-2, but there are no more extensive studies proving their efficacy. In this study, the latest publications in the field have been reviewed, focusing on the modulatory effects on the immunity of some natural antiviral dietary supplements, vitamins and minerals. Findings suggest that several dietary supplements, including black seeds, garlic, ginger, cranberry, orange, omega-3 and -6 polyunsaturated fatty acids, vitamins (e.g., A, B vitamins, C, D, E), and minerals (e.g., Cu, Fe, Mg, Mn, Na, Se, Zn) have anti-viral effects. Many of them act against various species of respiratory viruses, including severe acute respiratory syndrome-related coronaviruses. Therefore, dietary supplements, including vitamins and minerals, probiotics as well as individual nutritional behaviour can be used as adjuvant therapy together with antiviral medicines in the management of COVID-19 disease.

Epigenetic modifications associated with genes implicated in cytokine storm: The potential biotherapeutic effects of vitamins and minerals in COVID-19.

Cytokine storm is a phrase used to refer to an abrupt upsurge in the circulating levels of various pro-inflammatory cytokines, causing increased stimulation and activity of immune cells during disease conditions. The binding of pattern recognition receptors to pathogen-associated molecular patterns during COVID-19 infection recruits response machinery involving the activation of transcription factors and proteins required for a robust immune response by host cells. These immune responses could be influenced by epigenetic modifications as evidenced by significant variations in COVID-19 pathophysiology and response to therapy observed among patients across the globe. Considering that circulating levels of interleukin 1, tumor necrosis factor-α, and interleukin 6 are significantly elevated during cytokine storm in COVID-19 patients, genetic and epigenetic variations in the expression and function of these proteins could enhance our understanding of the disease pathogenesis. Treatment options that repress the transcription of specific cytokine genes during COVID-19 infection could serve as possible targets to counteract cytokine storm in COVID-19. Therefore, the present article reviews the roles of cytokines and associated genes in the COVID-19 cytokine storm, identifies epigenetic modifications associated with the disease progression, and possible ameliorative effects of some vitamins and minerals obtained as epigenetic modifiers for the control of cytokine storm and disease severity in COVID-19 patients. PRACTICAL APPLICATIONS: COVID-19 causes mortality and morbidity that adversely affect global economies. Despite a global vaccination campaign, side effects associated with vaccination, misconceptions, and a number of other factors have affected the expected successes. Cytokine storm in COVID-19 patients contributes to the disease pathogenesis and response to therapy. Epigenetic variations in the expression of various cytokines could be implicated in the different outcomes observed in COVID-19 patients. Certain vitamins and minerals have been shown to interfere with the expression and activity of cytokines implicated in cytokine storm, thereby counteracting observed pathologies. This review examines cytokines implicated in cytokine storm in COVID-19, epigenetic modifications that contribute to increased expression of identified cytokines, specific foods rich in the identified vitamins and minerals, and suggests their possible ameliorative benefits. The article will be beneficial to both scientists and the general public who are interested in the role of vitamins and minerals in ameliorating COVID-19.

Beneficial Effects of Vitamins, Minerals, and Bioactive Peptides on Strengthening the Immune System Against COVID-19 and the Role of Cow's Milk in the Supply of These Nutrients.

The COVID-19 pandemic, which causes severe respiratory tract infections in humans, has become a global health concern and is spreading rapidly. At present, the most important issue associated with COVID-19 is the immune system and the factors that affect it. It is well known that cow's milk is highly rich in micronutrients that increase and strengthen the immune system. Research shows that the administration of these nutrients is very effective in fighting COVID-19, and a deficiency in any of them can be a weakness in the fight against the virus. On the other hand, cow's milk is accessible to the whole population, and drinking colostrum, raw, and micro-filtered milk from cows vaccinated against SARS-CoV-2 could provide individuals with short-term protection against the SARS-CoV-2 infection until vaccines become commercially available. This review aimed to discuss the effects of milk vitamins, minerals, and bioactive peptides on general health in humans to combat viral diseases, especially COVID-19, and to what extent cow's milk consumption plays a role in providing these metabolites. Cow's milk contains many bioactive compounds that include vitamins, minerals, biogenic amines, nucleotides, oligosaccharides, organic acids, and immunoglobulins. Humans can meet a significant portion of their requirements for vitamins and minerals through the consumption of cow's milk. Recent studies have shown that micronutrients such as vitamins D, E, B, C, and A as well as minerals Zn, Cu, Mg, I, and Se and bioactive peptides, each can have positive and significant effects on strengthening the immune system and general health in humans.

[Mineral metabolism and COVID-19: is there a connection?]

Due to global spread of COVID-19, the search for new factors that could influence its clinical course becomes highly important. This review summarize the relevant publications on the association between immune system and the main regulators of mineral homeostasis including. In addition, we have highlighted the various aspects of phosphorus-calcium metabolism related to the acute respiratory diseases and in particular to COVID-19. The data about the calcium-phosphorus metabolism in SARS-CoV-2 infection is required to understand the possible clinical implications and to develop new therapeutic and preventive interventions.
