Impact of Vitamins on immunity

Human beings were blessed with two kinds of immunity, born immunity and acquired immunity. As a multisystem organism, we have distinct functions to carry out for the duration of our life. We are not the simplest ones residing on earth;however, different microorganisms coexist with us in near proximity. In a manner, we are making a symbiotic relationship with the opposite microorganism. Sometimes those can become dominant species and might invade the human body. As we are blessed with our immune system, we are able to prevent them. In a contemporary situation, nutrients and minerals have played a considerable function in immunity booster within the COVID-19. Wuhan changed the origin of this deadly virus, which brought on a pandemic in 2020. Basically, COVID-19 virus attacks the immune system and turns on distinct inflammatory modulators, which seriously affect the human body. A scientific practitioner and a team of researchers observed that multivitamins and some micronutrients can assist to enhance the immune system. Vitamins, including A, B, C, D, K and micro vitamins together with zinc, sodium, potassium, and calcium, play a main function in such deadly diseases. In this chapter, we have focused at the function of nutrients within the immunity and immune associated diseases. © 2023 Scrivener Publishing LLC. All rights reserved.

Immune enhancers for COVID-19

SARS-CoV-2, also known as COVID-19, is a novel coronavirus that began sweeping the globe at the end of 2019, causing mild illness in some patients while leading to devastating shock, immune dysregulation, multiorgan failure, and even death in others. Immune dysregulation may lead to increased susceptibility to severe disease from COVID-19. Immune enhancers could aid in immune regulation and protect against severe COVID-19 infection. Herbal supplements, spices, and lifestyle modifications have been shown to enhance immune responses to a number of pathogens, which may include COVID-19. These immune enhancers could be used adjunctively with vaccines, social distancing, and pharmacologic treatments to prevent life-threatening infection in susceptible patients. © 2023 Elsevier Inc.

Association of fat-soluble vitamins (A, D, and E) status with humoral immune response to COVID-19 inactivated vaccination.

Background: Fat-soluble vitamins (A, D, and E) are essential for the proper functioning of the immune system and are of central importance for infection risk in humans. Vitamins A, D, and E have been reported to be associated with the immune response following vaccination; however, their effects on the immune response to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccination remain unknown. Methods: We measured the neutralizing antibody titers against wild type and omicron within 98 days after the third homologous boosting shot of inactivated SARS-CoV-2 vaccine (BBIBP-CorV or CoronaVac) in 141 healthy adults in a prospective, open-label study. High-performance liquid chromatography-tandem mass spectroscopy was used to determine the concentrations of plasma vitamins A, D, and E. Results: We found that the anti-wide-type virus and anti-omicron variant antibody levels significantly increased compared with baseline antibody levels (P < 0.001) after the third vaccination. 25(OH)D3 was significantly negatively associated with the baseline anti-wide-type virus antibody concentrations [beta (95% CI) = -0.331 (-0.659 ~ -0.003)] after adjusting for covariates. A potentially similar association was also observed on day 98 after the third vaccination [beta (95% CI) = -0.317 (-0.641 ~ 0.007)]. After adjusting for covariates, we also found that 25(OH)D3 was significantly negatively associated with the seropositivity of the anti-omicron variant antibody at day 98 after the third vaccination [OR (95% CI) = 0.940 (0.883 ~ 0.996)]. The association between plasma 25(OH)D3 with anti-wild-type virus antibody levels and seropositivity of anti-omicron variant antibodies were persistent in subgroup analyses. We observed no association between retinol/α-tocopherol and anti-wide-type virus antibody levels or anti-omicron variant antibody seropositive in our study. Conclusion: The third inactivated SARS-CoV-2 vaccination significantly improved the ability of anti-SARS-CoV-2 infection in the human body. Higher vitamin D concentrations could significantly decrease the anti-wide-type virus-neutralizing antibody titers and anti-omicron variant antibody seropositive rate after the inactivated SARS-CoV-2 vaccination in people with adequate levels of vitamin D, better immune status, and stronger immune response; further studies comprising large cohorts of patients with different nutritional status are warranted to verify our results.

Vitamins and minerals, education, and self-care need during preconception to 1000 days of life in Southeast Asia: An expert panel opinion.

Addressing maternal malnutrition and its drivers is paramount in Southeast Asia. This article summarizes the key clinical learnings and evidence-based opinions from the experts to understand the need for vitamins and minerals supplementation, education, and self-care from preconception to the first 1000 days of life, which warranted further attention since COVID-19 pandemic. Evidence describing the importance of vitamins and minerals during preconception, pregnancy, and lactation stages was identified using literature databases. A pre-meeting survey was conducted to determine the current practices and challenges in Southeast Asia. Based on the literature review and clinical experience, experts defined the topics, and an online meeting was held on 13th July 2021. During the meeting, nine experts from Southeast Asia provided evidence-based opinion on the vitamins and minerals supplementation, education, and self-care need during preconception, pregnancy, and lactation stages. The expert opinions underpin maternal malnutrition as a prevalent issue and discuss appropriate interventions and prevention strategies for women in Southeast Asia. The recent pandemic further impacted nutrition status, pregnancy, and neonatal health outcomes. The expert panel emphasized a need to improve existing inadequacies in education, self-care, and social support, and discussed the role of policymakers in addressing the barriers to dietary changes. As inadequacies in regular vitamins and minerals supplementation, education, and self-care for women of reproductive age implicate maternal and child health outcomes, there is an urgent need for addressing malnutrition concerns in this population. Thus, a strong partnership between policymakers, healthcare professionals, and other relevant sectors is required.

Vitamin-D deficiency, the hidden pandemic in sunshine sufficient countries, exacerbating hypocalcaemia in a health worker undergoing thyroidectomy - a global perspective and review of literature

Introduction: Vitamin D deficiency (VDD) is common in young adults even in sunlight sufficient countries. It manifests with subtle and trivial symptoms that are often ignored. Nutritional deficiency due to improper dietary habits, poverty, long hours at work and study are factors. The lockdown during COVID has exacerbated the incidence. We had a patient with VDD who became symptomatic after routine thyroidectomy prompting our review into literature on the global health perspective of VDD. Material and method: - A 21-year-old nursing student developed hypocalcaemia within 24 hours after a routine thyroidectomy. VDD was detected and patient improved after supplementation. Literature was reviewed from Pubmed database for the medical aspects of the problem, from Government archives like the Scientific Advisory Committee on Nutrition, ICMR etc for cause and medical archives including those of paediatric and general health for the impact of disease at the state, national and global level. A global health problem list was prepared and data was reviewed. Discussion: Vitamin D is protective against respiratory infections due to viral aetiology including COVID. However, complete lockdown to prevent spread of COVID, online learning, and work from home culture has reduced sunlight exposure and increased incidence of VDD. Post thyroidectomy hypocalcaemia is common in VDD. Conclusion: Since there is a high prevalence of asymptomatic VDD even in sunshine sufficient countries, it is recommended to screen all patients especially young adults for VDD during routine preoperative work up.

Purchase Behavior According to the Development of Sustainable Pistachio (Pistacia vera L.) Rice Cake: For Korean Consumers

In recent years, the rice cake market has grown considerably in terms of research and development of products suitable for consumer needs and beneficial to health at the same time. Since the outbreak of COVID-19, the number of consumers consuming antioxidant-rich foods and immunity-boosting foods to improve health and promote healthy eating habits has increased. Pistachio rice cakes have been tested and found to be high in polyphenols, which have good antioxidant activity and strengthen the immune system. Therefore, research was conducted on pistachio rice cakes to develop safe, health functional, and sustainable food. In order to maximize the sales potential of pistachio rice cakes, a survey was conducted among Korean adults to investigate perception of pistachio, pistachio rice cake purchasing behavior, and popularization plans. Pearson's correlation analysis was performed to examine the correlation between pistachio perception, pistachio rice cake purchasing behavior, and pistachio rice cake popularization measures, and they were found to have a close relationship. In addition, as a result of multiple regression analysis, perception and purchasing behavior of pistachio rice cake products were found to have a significant positive (+) effect on rice cake technology development, development of brand specializing in rice cakes, and cultivation of traditional rice cake experts. This study suggests that continuous research and development of food safety and sustainability of rice cakes are required, and it is expected to be utilized as basic data to form a research basis that can be a strategy for increasing sales in the rice cake industry.

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.

Micronutrients absorbed via the oral mucosa reduce irritability and anger but not stress in university students during COVID-19: A randomized placebo-controlled trial

Research has shown micronutrient capsules can reduce stress in clinical and nonclinical recipients. However, as individuals can struggle with taking capsules, the objective of this double-blind, randomized placebo-controlled trial was to investigate the efficacy and safety of treating stress and well-being using an alternative delivery methodology: a powder that is absorbed via the oral mucosa. Seventy-two mild-severely stressed students, assessed using the Depression Anxiety Stress Scale-21 (DASS-21), were randomized to placebo or micronutrients and took one powder pouch per day for 4 weeks. Seven (10%) dropped out with no group differences. Symptoms of stress, depression, anxiety, irritability, anger, sleep, diet, and side effects were measured with online questionnaires every 2 weeks. There were no group differences on the primary outcome measures of stress (DASS-21;d = 0.15, p = .525) and self-reported improvement (Modified Clinical Global Impressions-Improvement scale), with 17.1% of the micronutrient and 16.2% of the placebo group identifying themselves as "much" to "very much" improved. However, the micronutrient group experienced statistically significantly greater reduction in irritability (d = 0.54, p = .024) and anger (d = 0.62, p = .011) relative to placebo, measured with the Affective Reactivity Scale and the Abbreviated Profile of Mood States, respectively. No group differences were found on remaining measures, with both groups showing significant improvements. There were significantly more headaches and drowsiness reported in the micronutrient group. Belief in treatment assignment was significantly correlated to self-reported improvement (r = -0.247, p = .049). To conclude, the micronutrients were no better than placebo in reducing stress;nonetheless, the significant benefit on irritability requires further research.

Development of nutritional biscuits for children, rich in Fe and Zn, by incorporation of pumpkin (Cucurbita maxima) seeds powder, a healthy pharma food in current post COVID 19 period

During preparatory operations of pumpkin, for cooking and processing, usually peel and seeds are discarded as waste but pumpkin seeds are rich in macro and micro nutrients, a potential source of pharma foods. In present study biscuits were developed from pumpkin seeds powder, rich in Fe and Zn, for children to strengthen innate and adaptive immune system to combat current COVID 19 outbreak scenarios. Chemical analyses of pumpkin seeds powder, white flour and developed biscuits, with 0, 5, 10 and 15% replacement level of pumpkin seeds powder, were performed. Ash, fat, fiber, Fe and Zn contents were significantly higher in pumpkin seeds powder as compared to white flour. By increasing the replacement level of pumpkin seeds powder with white flour, a significant increase in ash, fat, fiber, Fe and Zn, in biscuits was observed. In control (T0) the contents were, ash (0.57%), fat (30.36%), fiber (0.37%), Fe (2.44 mg/100 g) and Zn (1.45 mg/100 g) but when supplementation level was increased to 15% (T3) these contents were increased as, ash (1.65%), fat (32.46%), fiber (1.24%), Fe (4.23 mg/100 g) and Zn (4.37 mg/100 g). In current post COVID 19 scenario adequate supply of healthy diet, balanced with pharma foods could play a basic role in boosting immune system of the children. Concerns of the food processors has raised the choice of new food products enriched with immunity booster nutrients. These nutritious biscuits can be developed, marketed and consumed at mass levels to provide the basic nutrients to the developing communities.

Clinically proven natural products, vitamins and mineral in boosting up immunity: A comprehensive review.

Background: and Purposes: The terminology "immune boost-up" was the talk of the topic in this Covid-19 pandemic. A significant number of the people took initiative to increase the body's defense capacity through boosting up immunity worldwide. Considering this, the study was designed to explain the natural products, vitamins and mineral that were proved by clinical trail as immunity enhancer. Methods: Information was retrieved from SciVerse Scopus ® (Elsevier Properties S. A, USA), Web of Science® (Thomson Reuters, USA), and PubMed based on immunity, nutrients, natural products in boosting up immunity, minerals and vitamins in boosting up immunity, and immune booster agents. Result: A well-defined immune cells response provide a-well functioning defense system for the human physiological system. Cells of the immune system must require adequate stimulation so that these cells can prepare themselves competent enough to fight against any unintended onslaught. Several pharmacologically active medicinal plants and plants derived probiotics or micronutrients have played a pivotal role in enhancing the immune boost-up process. Their role has been well established from the previous study. Immune stimulating cells, especially cells of acquired immunity are closely associated with the immune-boosting up process because all the immunological reactions and mechanisms are mediated through these cells. Conclusion: This article highlighted the mechanism of action of different natural products, vitamins and mineral in boosting up the immunity of the human body and strengthening the body's defense system. Therefore, it is recommended that until the specific immune-boosting drugs are available in pharma markets, anyone can consider the mentioned products as dietary supplements to boost up the immunity.

Natural Ingredients to Improve Immunity.

The immune system protects the body from infectious agents such as bacteria, viruses, or fungi. Once encountered with pathogens or antigens, the innate and adaptive arms of the immune system trigger a strong immune response to eliminate them from the system and protect the body. Thus, well-balanced immunity is pivotal for maintaining human health, as an insufficient level of immune defense leads to infections and tumors. In contrast, the excessive functioning of the immune system causes the development of autoimmune diseases and allergies. Strong immunity requires adequate nutrition, dietary interventions, and sufficient intake of certain vitamins (vitamin C, vitamin D, and folic acid) and minerals (magnesium, zinc, and selenium). Therefore, nutritional and micronutrient deficiencies lead to compromised immunity. Several natural ingredients have shown potent immunomodulatory properties. The immune-enhancing properties of many plants and fungi are due to containing bioactive phytoconstituents such as polyphenols, terpenoids, ß-glucans, vitamins, etc. Probiotics and prebiotics can be used as innovative tools to reduce intestinal inflammation and downregulate hypersensitivity reactions. Plant sources of melatonin, a multifunctional molecule with proven anti-inflammatory and immunomodulatory properties, have been discovered relatively recently. The bioactive compounds augment the immune response by directly increasing the cytotoxic activity of natural killer cells, macrophages, and neutrophils. Many phytoconstituents prevent cell damage due to their powerful antimicrobial, antioxidant, and anti-inflammatory properties. The present review attempts to understand the molecular mechanisms underlying the immune-enhancing properties of some bioactive compounds from plants, fungi, animals, microorganisms, and other natural sources.

Correlation between Dietary Intake of Vitamins and Oral Health Behaviors: A Cross-Sectional Study.

This study aimed to investigate whether oral health behaviors were related to the dietary intake of vitamins. In this cross-sectional study, we included respondents of the 2016 national health and nutrition examination survey, and dental diseases from Hyogo Prefecture, Japan. Data on sociodemographic characteristics, findings of blood tests related to metabolic syndrome, dietary intake, oral health status, and behaviors were collected. Participants were divided into two groups based on their oral health behavior: the yes group (performed interdental cleaning or tongue brushing) and the no group (did not perform the behaviors). The study included 218 participants (male: 107, female: 111) aged 64.5 (range, 22-93) years. There were 133 (61.0%) and 85 (39.0%) participants in the yes and no groups, respectively. The daily intake of vitamins A, B2, B6, E, and K, folic acid, and niacin in the yes group was significantly higher than that in the no group. Oral health behavior correlated with the intake of vitamin B2 (p = 0.029), folic acid (p = 0.006), and vitamin K (p = 0.043) after adjusting for possible confounders. Oral health behavior (interdental cleaning or tongue brushing) correlated with the daily intake of vitamins B2, K, and folic acid.

A Synthesis Review of Vitamins Involved in the Fight against Covid-19

Although literature studies on earlier viruses such as the Severe Acute Respiratory Syndrome (SARS), the Middle East Respiratory Syndrome (MERS), and other similar viruses, in terms of treatment of coronavirus suggested the repurposing of some antiviral drugs, some Covid-19 specific treatments, general forms of treatments, the use of convalescent plasma, as well as nutritional interventions in the form of vitamins, it is imperative to interrogate the nutritional status, age, and comorbidities of each infected patient before receiving any form of treatment. In the absence of any conclusive treatment so far, the study encourages the use of all likely interventions that could help arrest the spread of the disease. In addition, the current study has a particular interest in the syntheses and applications of vitamins and their derivatives which have been touted to play a significant role in the fight against Covid-19, namely, vitamins A–E. It must, however, be mentioned that literature is not comprehensive. © 2023 Wiley-VCH GmbH.

Investigation of anxiety among pharmacy students during the COVID-19 pandemic in Northern Cyprus

Background: Anxiety is common among university students and previous research has highlighted the association between the COVID-19 pandemic and higher anxiety scores in the public. Objectives: In this regard, this study aimed to evaluate the effect of the COVID-19 pandemic on the anxiety status of pharmacy students studying in Northern Cyprus and analyze the role of some parameters on the observed anxiety scores. Methods: Anxiety scores of 185 pharmacy students studying at two universities in Northern Cyprus were evaluated using Beck Anxiety Inventory (BAI) and Generalized Anxiety Disorder-7 (GAD-7) assessments. Additionally, the information of participants was recorded in terms of sociodemographic and educational characteristics, antidepressants and anxiolytic use, and consumption of vitamin-mineral supplements. The questionnaires were distributed during the COVID-19 pandemic from December 11, 2020, to January 4, 2021, online via the Microsoft TeamsR platform. It should be mentioned that responses were anonymous. Results: The mean BAI and GAD-7 scores of pharmacy students were 13.1+or-11.2 and 10+or-6.7, respectively. Based on the results, 6% of the students (n=11) revealed potentially concerning levels of anxiety in their BAI responses. Moreover, 31.9% of the pharmacy students (n=59) demonstrated severe anxiety scores on the GAD-7. Positive COVID-19 cases in the family led to statistically significant increases in anxiety on both instruments. Pharmacy students with five years of education (B. Pharm/M. Pharm) showed significantly higher anxiety scores on the BAI. Besides, age correlated negatively with anxiety scores on the GAD-7. Neither antidepressant and anxiolytic use nor vitamin/mineral supplement use were not related to the anxiety scores of participants. Conclusion: Results of this study demonstrated an alarming anxiety status among pharmacy students during the COVID-19 pandemic period. Diagnosis of a family member with COVID-19 was observed to be critical in triggering the anxiety of pharmacy students. Data from this study should raise awareness to take action plans for the mental well-being of pharmacy students during pandemics.

Patients' diets in Latvian psycho-neurological hospitals

The role of nutrition in the treatment of diseases is known, and it can be a contributing and hindering factor which can shorten or prolong the time of treatment. Studies on mental health have shown that the inclusion of certain nutrient in increased amounts in patients' diet can have a positive effect on the treatment of depression, anxiety etc. The COVID-19 pandemic increases the risk of depression in general population, which means an increased number of patients in need of professional help. Therefore, the aim of the study was to evaluate the patients' diets in Latvian psycho-neurological hospitals, emphasizing the provision of certain nutrients which are essential for mental health. There were analyzed a one-week menu at three Latvian psycho-neurological hospitals. Provision of nutrients (minerals, vitamins, fatty acids) in patients' diets was calculated using Finish food composition database. Basic conditions for provision of patients' diet are determined by the regulation of the Cabinet of Ministers, indicating the daily variety of energy value, minimum and maximum amount of proteins, fats and carbohydrates. The obtained results regarding patients' diets were processed using MS Excel and SPSS Statistics 22. The required amount of nutrients per day can be achieved with a variety of foods which in turn can significantly affect the concentration of minerals and vitamins and profile of fatty acids in the diet. In general, the provision of minerals and vitamins in hospitals' diets was close to the recommendations of a healthy person, but it was not sufficient for psycho-neurological hospital patients. It would be desirable to raise their concentration by increasing the amount of vegetables and fruits in the diet. Analysis of fatty acid profile in patients' diets showed significant differences depending on whether fish or meat products were included. It would be advisable to increase the concentration of omega-3 fatty acids. In general, the nutrition provision for patients of psycho-neurological hospitals could be assessed as sufficient, but several aspects need to be improved. Vitamin D intake should be significantly increased as it didn't reach the generally recommended dose. Fruit should be included and the amount of vegetables should be increased to provide a recommendation of at least 400 g per day, which in turn will increase the intake of vitamins and minerals.

Omega 3 Fatty Acids' Effects on COVID-19

Recently, the novel coronavirus, which is called severe acute respiratory syndrome coronavirus 2, has been responsible for the highly rapid spread of COVID-19 disease, globally. Until now, 535 million people were affected and 6.3 million people died due to this outbreak throughout the World. Although the lethality of this disease is lower than the severe acute respiratory syndrome coronavirus and Middle East respiratory syndrome, severe complications of this disease are attributed to "cytokine storm” that is the reason for the severe lung damage. The cytokine storm causes systemic inflammation, acute respiratory distress syndrome, septic shock, stroke, multiple organ dysfunction, and death. As a result of these symptoms, there are pivotal studies about vaccination, drug, and medication to prevent severe complications and treat patients with COVID-19. Besides these studies, some research shows that nutrients are able to manage the cytokine storm such as many types of vitamins, trace elements, and omega 3 fatty acids. Omega 3 polyunsaturated fatty acids have specific roles in the inflammatory process. Omega 3 fatty acids have a role in the improvement of the inflammatory balance. They interact with viral infection in disparate stages such as viral entry and replication. This study highlights the roles of omega 3 polyunsaturated fatty acids in the prevention and treatment of the COVID-19. In addition, omega 3 fatty acids show anti-viral and anti-inflammatory effects on the severe acute respiratory syndrome coronavirus 2 and increase survival rates in patients infected with COVID-19.

The association between chest CT severity scores, CO-RADS, vitamin D levels and other laboratory parameters of COVID-19 patients

Objective: This study determined the correlation between several laboratory variables, chest computed tomography severity score (CTSS), and coronavirus disease-2019 (COVID-19) Reporting and Data System (CO-RADS) in COVID-19 patients. Materials and Methods: Ninety-one patients with COVID-19 infection verified by polymerase chain reaction test, presented to the emergency department with COVID-19 symptoms, and had a thoracic computed tomography (CT) scan at the time of admission were included in this retrospective study. 25-hydroxyvitamin D [25(OH)D] levels, erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), D-dimer, glucose, ferritin, creatinine, alanine aminotransferase, aspartate aminotransferase, phosphorous, and calcium levels recorded and CO-RADS and CTSS data. The correlation of laboratory parameters with radiological findings was analyzed. Results: A positive correlation was found between CTSS and age, ESR, CRP, D-dimer while a negative correlation was found between CTSS and lymphocyte count. Patients with high CTSS levels had higher ESR, CRP, D-dimer, ferritin values and lower lymphocyte count, and lower calcium levels. Patients with typical CO-RADS involvement had higher sedimentation, CRP, glucose, and ferritin levels and lower lymphocyte count. No significant correlation was determined between the 25(OH)D level, CO-RADS, and CTSS. Conclusion: The results of this study highlight that the reduced lymphocyte count, high D-dimer, sedimentation, ferritin, and CRP levels are predictors of severe lung involvement in COVID-19 patients. Hypocalcemia can also be considered a marker of severe lung involvement evaluated by CT in COVID-19 patients. the association between vitamin D deficiency and COVID-19 pneumonia should be investigated in future studies.

A review on biochemical constituents of pumpkin and their role as pharma foods, a key strategy to improve health in post COVID 19 period

Progression of today's world has been given setback due to the adversity of a novel, viral, deadly outbreak COVID 19, which raised the concerns of the scientists, researchers and health related officials about the inherent and adaptive immune system of the living body and its relation with healthy diet balanced with pharma foods. Now world is coming out of the destructive pandemic era, the choice of right food can help to build and boost adaptive immunity and pumpkin due to excellent profile of functional and nutraceutical constituents could be the part of both infected and non-infected person's daily diet. Vitamins like A, C and E, minerals like zinc, iron and selenium, essential oils, peptides, carotenoids and polysaccharides present in pumpkin could accommodate the prevailing deficiencies in the body to fought against the viral pathogens. In current post COVID 19 scenario adequate supply of healthy diet, balanced with pharma foods could play a basic role in boosting immune system of the populations. This review covers the pharmacological activities of pumpkin functional constituents in relation with COVID 19 pandemic. Pumpkins are well equipped with nutraceuticals and functional bioactives like tocopherols, polyphenols, terpenoids and lutein therefore, consumption and processing of this remarkable vegetable could be encouraged as pharma food due to its antihyperlipidemic, antiviral, anti-inflammatory, antihyperglycemic, immunomodulatory, antihypertensive, antimicrobial and antioxidant potential. Need of healthy eating in current post COVID 19 period is very crucial for healthy population, and medicinal foods like pumpkin could play a vital role in developing a healthy community around the globe.

Macronutrient and micronutrient requirements and therapeutic effects in critically ill patients with SARS-CoV-2: A narrative review.

BACKGROUND: COVID-19 can lead to critical illness and induce hypermetabolism, protein catabolism, and inflammation. These pathological processes may alter energy and protein requirements, and certain micronutrients may attenuate the associated detriments. This narrative review summarizes the macronutrient and micronutrient requirements and therapeutic effects in critically ill patients with SARS-CoV-2. METHODS: We searched four databases for randomized controlled trials (RCTs) and studies that measured macronutrient and micronutrient requirements, published from February 2020 to September 2022. RESULTS: Ten articles reported on energy and protein requirements, and five articles reported the therapeutic effects of ω-3 (n = 1), group B vitamins (n = 1), and vitamin C (n = 3). Patients' resting energy expenditure gradually increased with time, measuring approximately 20 kcal/kg body weight (BW), 25 kcal/kg BW, and 30 kcal/kg BW for the first, second, and third week onwards, respectively. Patients remained in negative nitrogen balances in the first week, and a protein intake of ≥1.5 g/kg BW may be necessary to achieve nitrogen equilibrium. Preliminary evidence suggests that ω-3 fatty acids may protect against renal and respiratory impairments. The therapeutic effects of group B vitamins and vitamin C cannot be ascertained, although intravenous vitamin C appears promising in reducing mortality and inflammation. CONCLUSION: There are no RCTs to guide the optimal dose of energy and protein in critically ill patients with SARS-CoV-2. Additional larger-scale, well-designed RCTs are needed to elucidate the therapeutic effects of ω-3, group B vitamins, and vitamin C.
