RETROSPECTIVE STUDY OF VITAMIN D DEFICIENCY IN RHEUMATOLOGIC PATIENTS DURING THE COVID-19 PANDEMIC IN POLAND

BackgroundBefore the COVID-19 pandemic it was estimated that nearly 70% of the population is deficient in vitamin D - 25(OH)D <20ng/ml in Poland [1]. The percentage was expected to increase due to indoor isolation during the COVID-19 pandemic. Vitamin D has a positive effect on the condition of the bones, affects the course of autoimmune diseases, the course of neurological diseases, in type 2 diabetes, vitamin D supplementation improves glucose tolerance and reduces insulin resistance [2,3,4].ObjectivesThe aim of the retrospective study was to determine what percentage of rheumatology clinic patients suffer from vitamin D deficiency and whether this condition is effectively treated.MethodsIn January 2023, a retrospective analysis of the documentation of 172 patients treated at the Rheumatology Outpatient Clinic in Bełżyce (Poland) in 2022 was conducted.ResultsResults: The mean age of the 172 patients whose documentation was analyzed was 60.43 years (min 19, max 88). There were 132 women (76.8%) and 40 men (23.2%) in this group. The mean concentration of vitamin D was 25.57ng/ml±SD11.9 (min 5.7, max 75, Me 22.8). Vitamin D deficiency was found in 44% (serum concentration <20mg/ml), suboptimal concentration (20-30ng/ml) in 31%, optimal concentration (30-50ng/ml) in 21%, and high concentration (>50ng/ml) ml) in 4%. All those with a deficit or deficiency (75 people) were prescribed cholecalciferol in a dose of 20,000 units orally, 1 capsule twice a week after breakfast for 2 months [5]. Patients with optimal vitamin D levels were advised to take a dose of 2,000 units per day. Among the patients with deficit or deficiency, 48 people came for a follow-up visit to check the level of vitamin D (64% of the group with too low vitamin D concentration;28% of the entire group whose documentation was analyzed). In the follow-up examination, the mean concentration of vitamin D was 37.14±9.8ng/ml (min 28, max 84, Me 35.3). Therefore, a statistically significant increase in the concentration of vitamin D in the blood was noted (p<0.05). In the group of people who came for the follow-up examination, there were 35 women, whose mean age was 60.7 years and 13 men (mean age 68.2 years).Conclusion:1. During the COVID-19 pandemic in the group of outpatient rheumatology patients, 75% had a deficiency or suboptimal level of vitamin D.2. Treatment with cholecalciferol in a dose of 20,000 IU twice a week orally for 2 months is effective treatment of vitamin D deficiency.3. Too low percentage of patients diagnosed with vitamin D deficiency come for visits and check-ups.References[1]Hilger J., Friedel A., Herr R..

Was COVID-19 pandemic anxiety reflected on nutritional habits in adults?

PurposeThis study aims to evaluate the reflection of COVID-19 pandemic anxiety experienced in adults on nutritional habits during the COVID-19 pandemic in Turkey.Design/methodology/approachThe study was conducted with 600 adults aged between 19 and 64 years. The general characteristics of the individuals, nutritional habits, use of dietary supplements and COVID-19 pandemic anxiety before and during the pandemic period were questioned via a Web-based questionnaire. COVID-19-related anxiety was assessed using The COVID-19 Phobia Scale (C19P-S) and The State-Trait Anxiety Inventory (STAI). Data analysis was performed using the Statistical Package for Social Sciences, version 24.0.FindingsIn this study, 49.8% of the participants stated that their appetite and food consumption amount increased during the pandemic period. The rate of use of dietary supplements among individuals was found to be 40%. It was observed that the mean body weight and body mass index increased significantly in both genders during the COVID-19 pandemic. It has been determined that anxiety about COVID-19 is higher in individuals and women who start using nutritional support during the pandemic period. The total C19P-S and STAI scores of those who started using a dietary supplement during the pandemic were significantly higher than those who did not use a dietary supplement. Similarly, those whose eating habits changed positively and those who bought more packaged products had higher C19P-S scale mean scores (p < 0.05).Originality/valueDuring the COVID-19 period, it is important to reduce the anxiety levels of individuals, provide psychological support, raise awareness of adequate and balanced nutrition and the correct use of dietary supplements to adapt to the new lifestyle.

Association between Consumption of Dietary Supplements and Chronic Kidney Disease Prevalence: Results of the Korean Nationwide Population-Based Survey.

Despite the enormous global market of dietary supplements, the impact of dietary supplements on kidney disease is still unclear. Based on the National Health and Nutrition Examination Survey from 2015 to 2017, this study evaluated the association between dietary supplement and chronic kidney disease (CKD) in 13,271 Korean adults. Among the dietary supplements, vitamin and mineral intake was the highest at 61.41%, followed by omega-3 fatty acids at 11.85%, and ginseng at 7.99%. The prevalence of CKD was significantly higher in those who consumed amino acids and proteins, ginseng and red ginseng, and herbal medicine (plant extract)-berries than in those who did not. Conversely, patients who consumed probiotic supplements had a significantly lower prevalence of CKD than those who did not. In the population without CKD risk factors or history of CKD, the prevalence of CKD was high in the group consuming ginseng and red ginseng. After adjusting for covariates, the herbal medicine (plant extract)-berry group showed an independent association with CKD incidence. In conclusion, it is suggested that dietary supplements may affect kidney function. Further large-scale cohort studies are required to elucidate the exact effects of each dietary supplement on CKD.

Knowledge and attitudes towards herbal and dietary products use during the COVID-19 pandemic.

Background and aim: The outbreak of coronavirus (COVID-19) has made a global public health disaster. Little information is known about how to combat this infection. Therefore, preventive health measures that can reduce the severity and progression of this disease are needed. Some dietary supplements and herbal products have antiviral and anti-inflammatory effects. Thus, it may be used to enhance immunity and reduce the risk of COVID-19 infection. In this study, we reviewed selected supplements that may play a key role in the prevention and management of COVID-19 (e.g. vitamin D, vitamin C, and zinc), and that was to determine the level of knowledge and attitudes toward them by the adult population in Jordan. Methodology: This is a cross-sectional study design, in which an online questionnaire was conducted and distributed on different social media websites. People who are above 18 years old were included in this study. Demographic, Attitudes, and knowledge data were collected and then analyzed using the Statistical Package for Social Sciences (SPSS 23). Results: In this study, (62.8%) of participants became more concerned with their health during the COVID-19 pandemic, and (49.2%) of them used dietary and herbal supplements to protect themselves from the coronavirus. In addition, (18.5%) of participants reported that they had used these supplements for a while and then stopped. Conclusion: The findings of our study provided evidence that the general population in Jordan has a reasonable level of knowledge and acceptance of dietary and herbal supplements used during the COVID-19 pandemic.

Dietary supplements' knowledge, attitude and consumption pattern among United Arab Emirates population

PurposeTo study the consumption pattern, attitude and knowledge of the general population about dietary supplements (DS) in the United Arab Emirates (UAE).Design/methodology/approachA community-based cross-sectional study was conducted to collect data on knowledge, attitude and consumption pattern related to the use of DS. Participants aged = 18 years were asked to complete a self-administered online questionnaire that included demographic characteristics, health and lifestyle information, consumption patterns, attitudes and knowledge levels regarding the use of DS.FindingsA total of 207 individuals participated in the study, and 117 (56.5%) participants reported using DS products as influenced by the pandemic of coronavirus disease 2019 (COVID-19), of which 63 (53.8%) participants had been using DS for more than one month but less than one year. The majority of the participants was females (64.7%), non-UAE nationals (60.9%) and employed (51.7%). Multivitamins (77.8%) were the most commonly used DS. Use of DS was more prevalent among older participants (n = 78 (61.9%), p = 0.006), non-UAE nationals (n = 79 (62.7%), p = 0.025) and employed (n = 69 (64.5%), p = 0.023). Improving general health (76.1%) and immune booster (47%) were the most frequently identified reasons for using DS, which is relatable to the COVID-19 pandemic. The majority of study participants (72.12%) reported knowing relatively little about the use of DS. About 154 participants (74.4%) did not know that DS products do not treat diseases.Research limitations/implicationsFurther studies with a larger sample size need to be conducted to examine the association between gender or chronic disease and the consumption and type of DS products used to fill the gap in the literature and overcome the limitations identified in this study.Originality/valueThis study highlights the need for community education programs and strategies that can raise awareness of the health benefits and risks of using DS. Further studies with a larger sample size need to be conducted to examine the association between gender or chronic disease and the consumption and type of DS products used to fill the gap in the literature and overcome the limitations identified in this study.

Research and Development of a New Sustainable Functional Food under the Scope of Nutrivigilance

Background: The New Global Economy is represented by a series of major features, such as the use of green energy, the reduction of the carbon footprint in all industrial and civil fields, as well as finding alternative food resources. Our main objective was the research of a sustainable food product with a special nutritional purpose in the vision of nutrivigilance, developed in Romania, as an adjuvant in the repair of gastric mucosa. Methods: The materials used in the research and development of the new food are the following: inulin, lactoferrin, sericin, and sodium bicarbonate. The new adjuvant food product in the repair of the gastric mucosa was added to certain foods in order to prevent the patients from being satiated by a single food from a sensory point of view. The resulting food products were organoleptically and physico-chemically analyzed. Results: The new food is sustainable and has versatile uses. It can be hydrated with water, non-carbonated drinks, mixed with cottage cheese, or with fruit puree and oatmeal. It is stable under normal storage conditions and microbiologically safe. Conclusions: Through its versatile use, the new food product for special nutritional conditions represents a worldwide novelty. Through the development of forestry for the cultivation of white or black mulberry (Morus alba and Morus nigra), the raising of silkworms (Bombyx mori), the processing of fibroin to obtain natural silk and the processing of sericin resulting as a residue in the textile industry, the new food product developed actively contribute to the global economy II.

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.

Therapeutic and Dietary Support for Gastrointestinal Tract Using Kefir as a Nutraceutical Beverage: Dairy-Milk-Based or Plant-Sourced Kefir Probiotic Products for Vegan and Lactose-Intolerant Populations

Kefir is a fermented milk beverage different in consistency and taste from other popular milk-product yogurt. Unlike yogurt prepared using lactic acid bacteria in fermentation, milk is fermented for kefir production using preculture in the form of kefir grains. Therefore, the metabolic activities of a mixed culture, including strains of bacteria and yeast, contribute to the probiotic characteristics in kefir. This article is based on the review of published studies on the functionality and nutraceutical properties of kefir. The therapeutic and dietary properties of kefir beverage and its probiotic strains have been discussed for their several health benefits. Concise selected information mostly from recent reports has been presented for two categories of kefir products: milk used for the production of dairy-based traditional kefir beverages for the lactose-tolerant population, and the plant-sourced substrates used for the production of dairy-free kefir beverages for lactose-intolerant and vegan consumers.

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.

Nutrition Intervention for Undernourished Older Adults amid the COVID-19 Pandemic

Background: Older adults are vulnerable to disease exposure because of the agerelated decrease in immune capacity. Older adults with macronutrient and micronutrient deficiencies may have poor nutritional status and low immune responses, making them prone to COVID-19 infection.Objective: This study aimed to assess the effect of orange almond potato cookie supplementation on weight, hemoglobin, and albumin levels in undernourished older adults during the COVID-19 pandemic.Methods: A quasi-experimental study design was utilized in a cohort of 31 older adults. The subjects consumed 50 grams of cookies per day for 4 weeks. The examination was performed to assess the hemoglobin and albumin levels at pre- and post-study timepoints. Education about balanced nutrition and anemia was provided throughout the study using leaflets, flipcharts, and videos. The subjects were weighed weekly to assess compliance;cookies were distributed, and a daily food consumption record was collected three times a week during home visits.Results: Weight, hemoglobin, and albumin levels increased by 0.4 kg, 0.1 points, and 1 point, respectively. The difference was significant for weight, albeit nonsignificant for hemoglobin and albumin levels. At the end of the study, participants' knowledge regarding balanced nutrition and anemia was statistically significantly different, as well as that of energy, carbohydrate, protein, fat, vitamin C, and iron intake. Weight gain was found to be influenced by the total cookie consumption (p < 0.035).Conclusion: Orange almond potato cookies increased the undernourished older adults' weight when consumed for 4 weeks.

Curcumin Confers Anti-Inflammatory Effects in Adults Who Recovered from COVID-19 and Were Subsequently Vaccinated: A Randomized Controlled Trial.

COVID-19 infection and vaccination offer disparate levels of defense against reinfection and breakthrough infection. This study was designed to examine the effects of curcumin supplementation, specifically HydroCurc (CURC), versus placebo (CON) on circulating inflammatory biomarkers in adults who had previously been diagnosed with COVID-19 and subsequently received a primary series of monovalent vaccine doses. This study was conducted between June 2021 and May 2022. Participants were randomized to receive CURC (500 mg) or CON capsules twice daily for four weeks. Blood sampling was completed at baseline and week-4 and analyzed for biomarkers. Linear regression was utilized to examine the between-group differences in post-trial inflammatory biomarker levels, adjusting for baseline and covariates including age, sex, race/ethnicity, and interval between COVID-19 diagnosis and trial enrollment. The sample (n = 31) was 71% female (Age 27.6 ± 10.4 y). The CURC group exhibited significantly lower post-trial concentrations of proinflammatory IL-6 (ß = -0.52, 95%CI: -1.03, -0.014, p = 0.046) and MCP-1 (ß = -0.12, 95%CI: -0.23, -0.015, p = 0.027) compared to CON, adjusting for baseline and covariates. Curcumin intake confers anti-inflammatory activity and may be a promising prophylactic nutraceutical strategy for COVID-19. These results suggest that 4 weeks of curcumin supplementation resulted in significantly lower concentrations of proinflammatory cytokines in adults who recovered from COVID-19 infection and were subsequently vaccinated.

Content and economic evaluation of omega-3 fatty acid nutritional supplements

Marinederived omega3 fatty acids, namely eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) are abundant in seafood and fish oils. They are recommended for their many health benefits. There has been a large and sustained growth in sales of nutritional supplements containing omega3 fatty acids during the COVID-19 pandemic. In this study, a total of 54 omega3 fatty acids supplement products of various brands available in Turkey was analysed for their fatty acids content using gas chromatography. In 59.3 % of the products examined, EPA plus DHA content was found to be less than what was stated on the label. It was observed that 25.9 % could meet the daily EPA+DHA need with a capsule or a measure of consumption. Overall, 35.2 % of products were found satisfactory in terms of providing 80 % or more of the daily EPA+DHA requirement with a capsule or a measure of consumption and advantageous in terms of contents and price. The remaining 64.8 % of products could not provide 80 % of the daily EPA+DHA requirement with a single capsule. This study provided information on the accuracy of the declared contents of omega3 fatty acids supplements and evaluated the advantages for the consumers.

Association between COVID-19 vaccine side effects and history of nutritional supplement intake and body mass index (BMI): a retrospective study

PurposeAs the development and vaccination of the COVID 19 vaccine is accelerating worldwide, it is important to investigate the ways to improve immunity and immune responses to vaccines. This study aims to investigate the association between history of nutritional supplements intake and body mass index (BMI) in the severity of COVID-19 vaccine side effects after vaccination.Design/methodology/approachA total of 465 vaccinated participants with the Sinopharm vaccine (females and males in the 18–65 age range) participated in the study. Anthropometric measurements were taken on the first visit. In addition, nutrient supplement history and demographic information were collected. Moreover, the participants' phone numbers were collected and they were contacted. Participants were asked to report if they experienced systemic (whole-body) and/or local side effects after vaccination, in the following eight days. Then, participants were grouped into four categories: no symptoms (n = 232), mild symptoms (n = 121), moderate symptoms (n = 55) and severe symptoms (n = 57).FindingsThere was a significant difference between the consumption of nutritional supplements by different groups of participants in the last six months (considering the severity of the symptoms) (p < 0.001). The odds ratio (OR) and 95% confidence intervals (CI) for the incidence of side effects from the COVID-19 vaccine increased in the Q3 of BMI (range 22.94–26.34) in Modes 2 and 3: [OR: 1.85, (95% CI: 1.14– 3.00), p-for trend = 0.08] and [OR: 1.89, (95% CI: 1.16– 3.09), p-for trend = 0.09] based on logistic regression models.Originality/valueIn this study, the history of nutrient supplement intake affects the severity of side effects after the vaccination with COVID-19. Furthermore, based on logistic regression models, side effects were more prevalent in the BMI range 22.9–26.3 when compared to BMI < 20.2 so further study is necessary.

Potential Health Survey of Traditional Spices & Herbs in Prevention and Treatment of COVID-19: A Review

The coronavirus (COVID-19) is a global public health pandemic disease emerged from the novel strain of the coronavirus 2 (SARS-CoV-2) that caused severe acute respiratory syndrome. It is the most significant respiratory illness that has affected the world since World War II. Currently, there is no globally approved drug for the treatment of pandemic COVID-19 except for some recently approved vaccines. Instead, various non-specific treatment options are being utilized by different countries. While some of these are effective, there is a lack of well-documented studies on the impact of traditional medicines on the management of SARS-CoV-2 in vitro and in silico. For thousands of years, traditional healers have been using various herbs and spices products and dietary plants to treat various diseases. This review aims to provide information on the use of traditional spices & herbs in COVID-19 protection and treatment and present the main characteristics of these products and their potential antiviral actions. Various databases were searched for articles related to the use of various herbs for the treatment of viral infections. Many of these studies show that various plant compounds can be utilized for the treatment of viral infections. This study aims to summarize the common used of herbal products and dietary supplements with potent bioactive compounds in treatment or prevent of COVID-19.

Oral anticoagulants, dementia . . . and other stories

Anticoagulants conferred a small increase in life expectancy—but at the price of an increase in bleeding complications. Since the primary goal of treatment for patients with advanced dementia should surely be comfort, this may not be optimal care (J Am Ger Soc doi:10.1111/jgs.18108). Intravenous antihypertensives Rapid treatment may do more harm than good, according to a retrospective study of 20 000 adults who developed a systolic blood pressure of greater than 180 mm Hg or a diastolic pressure greater than 110 mm Hg while in hospital for a reason other than hypertension. Vitamin D supplementation and dementia A recent meta-analysis concluded that vitamin D supplementation had no useful protective effect on cognitive function.
