Nutritional recommendations for CoVID-19 quarantine

G. Muscogiuri, L. Barrea, S. Savastano et al.

The world is currently experiencing the pandemic of coronavirus (CoV). In late 2019, the CoV infection began in Wuhan, Hubei, China. It had been originally called 2019 nCoV and it has been renamed CoVID-19 by the World Health Organization on February 2020. This epidemic began with animal-to-human infection, and the direct cause of death is generally due to ensuing severe atypical pneumonia. CoVID-19 has now been declared a pandemic by the World Health Organization, and people in all countries are under quarantine in order to reduce the spread of the virus, which then also lessens the impact on medical resources. Since quarantine is associated to the interruption of the work routine, this could be result in boredom. Boredom has been associated with a greater energy intake, as well as the consumption of higher quantities of fats, carbohydrates, and proteins [1]. Further, during quarantine continuously hearing or reading about the pandemic without a break can be stressful. Consequently, the stress pushes people toward overeating, mostly looking for sugary “comfort foods” [2]. This desire to consume a specific kind of food is defined as “food craving”, which is a multidimensional concept including emotional (intense desire to eat), behavioral (seeking food), cognitive (thoughts about food), and physiological (salivation) processes [3]. Of interest, a gender difference has been reported in food craving, with a higher prevalence in women than in men. Carbohydrate craving encourages serotonin production that in turn has a positive effect on mood. In a sense, carbohydrate-rich foods can be a way of self-medicating anti stress. The effect of carbohydrate craving on low mood is proportional to the glycemic index of foods. This unhealthy nutritional habit could increase the risk of developing obesity that beyond being a chronic state of inflammation, it is often complicated by heart disease, diabetes, and lung disease that have been demonstrated to increase the risk for more serious complications of CoVID-19 [4]. Quarantinerelated stress also results in sleep disturbances that in turn further worsen the stress and increase food intake thus giving rise to a dangerous vicious cycle. Therefore, it is important to consume food containing or promoting the synthesis of serotonin and melatonin at dinner. A considerable variety of plant species including roots, leaves, fruits, and seeds such as almonds, bananas, cherries, and oats contain melatonin and/or serotonin. These foods may also contain tryptophan, which is a precursor of serotonin and melatonin. Protein foods such as milk and milk products are the main sources of the sleep-inducing amino acid tryptophan. Moreover, tryptophan is involved in the regulation of satiety and caloric intake via serotonin that mainly lowers carbohydrate and fat intake, and inhibits neuropeptide Y, the most powerful hypothalamic orexigen peptides [5]. Further, beyond sleep-inducing properties, milk products such as yogurt could also augmented natural killer cell activity and reduce the risk of respiratory infections [6] During quarantine the increased intake of macronutrients could also be accompanied by micronutrients deficiency as occurs in obesity [7], which is commonly associated with impaired immune responses, particularly cell-mediated immunity, phagocyte function, cytokine production, secretory antibody response, antibody affinity, and the complement system, thus making more susceptible to viral infections [8]. Thus, during this time it is important to take care of nutritional habits, following a healthy and balanced nutritional pattern containing a high amount of minerals, antioxidants, and vitamins. Several studies reported that fruits and vegetables supplying micronutrients can boost immune function. This happens because some of * Giovanna Muscogiuri giovanna.muscogiuri@gmail.com

Iron deficiency.

S. Pasricha, J. Tye-Din, M. Muckenthaler et al.

Iron deficiency is one of the leading contributors to the global burden of disease, and particularly affects children, premenopausal women, and people in low-income and middle-income countries. Anaemia is one of many consequences of iron deficiency, and clinical and functional impairments can occur in the absence of anaemia. Iron deprivation from erythroblasts and other tissues occurs when total body stores of iron are low or when inflammation causes withholding of iron from the plasma, particularly through the action of hepcidin, the main regulator of systemic iron homoeostasis. Oral iron therapy is the first line of treatment in most cases. Hepcidin upregulation by oral iron supplementation limits the absorption efficiency of high-dose oral iron supplementation, and of oral iron during inflammation. Modern parenteral iron formulations have substantially altered iron treatment and enable rapid, safe total-dose iron replacement. An underlying cause should be sought in all patients presenting with iron deficiency: screening for coeliac disease should be considered routinely, and endoscopic investigation to exclude bleeding gastrointestinal lesions is warranted in men and postmenopausal women presenting with iron deficiency anaemia. Iron supplementation programmes in low-income countries comprise part of the solution to meeting WHO Global Nutrition Targets.

Effects of supplementation with two probiotic strains (Lactobacillus helveticus and Bifidobacterium longum) on hormonal status, oxidative stress, and clinical symptoms in women with polycystic ovary syndrome: a randomized clinical trial

Mahsa Shirani, Mohammad Bagherniya, Omid Sadeghi et al.

Abstract Polycystic ovary syndrome (PCOS) is a common endocrine disorder affecting women. This study investigates the impact of 8-week supplementation with two probiotic strains, Lactobacillus helveticus and Bifidobacterium longum, on hormonal status, oxidative stress, and clinical symptoms in women with PCOS. Conducted as a double-blind, placebo-controlled, randomized clinical trial, the research involved 90 women with PCOS from Shahid Beheshti Hospital, Isfahan, Iran. Serum markers were assessed before and after the intervention. After adjusting for baseline values and confounding variables, the 8-week supplementation with two probiotic strains resulted in a significant increase in sex hormone binding globulin (24.39; 95% CI (15.23,33.55) vs. -11.99; 95% CI (-20.12, -3.86) nmol/L, P < 0.001), total antioxidant capacity (125.53; 95% CI (53.78,197.28) vs. -42.90; 95% CI (-78.32, -7.48) nmol/mL, P = 0.002) and Superoxide dismutase activity (0.19; 95% CI (0.09,0.30) vs. -0.11; 95% CI (-0.18, -0.04) U/mL, P < 0.001), in the intervention group compared to the placebo. While free androgen index (-57.05; 95% CI (-80.33, -33.76) vs. 49.86; 95% CI (28.81,70.92), P < 0.001), C-reactive protein (-0.50; 95% CI (-0.95, -0.04) vs. 0.05; 95% CI (-0.39,0.50), P = 0.046), and malondialdehyde levels (- 23.69; 95% CI (-30.02, -17.35) vs. -2.70; 95% CI (-9.19,3.77), P < 0.001), significantly decreased in the intervention group compared to the placebo. Furthermore, testosterone total levels showed a decreasing trend in the intervention group, although the between-group changes were not statistically significant after baseline value and other confounders adjustment (-3.37; 95% CI (-11.85, 5.11) vs. 6.48; 95% CI (3.43, 9.53) ng/dL, P = 0.08). Regarding clinical symptoms, including acne, alopecia, and hirsutism, the between-group changes were insignificant (P > 0.05). In conclusion, these findings suggest that 8 weeks of probiotic supplementation may alleviate oxidative stress, modulate certain hormonal factors, and reduce inflammation in women with PCOS. Trial registration, the current study was registered in the Iranian Registry of Clinical Trials on 30 March 2024 (ID: IRCT20121216011763N62) ( https://irct.behdasht.gov.ir/trial/76067 ). https://irct.behdasht.gov.ir/trial/76067 .

Validity and reliability of the Turkish version of the chrono-med diet score (CMDS) for adult participants

Tevfik Koçak, Emine Kocyigit, Duygu Ağagündüz

Abstract Background This study aimed to examine the validity and reliability of the Chrono-Med Diet Score (CMDS) to assess adherence to the Mediterranean diet in Turkish adults. Methods The methodological research conducted in Gümüşhane and Ordu from January to June 2024, including 592 individuals (62.3% women, 37.7% men, and the mean age 43.4 ± 10.6 years). Data were collected through face‒to‒face interview that contained socio-demographic characteristics, the CMDS, the Mediterranean Diet Adherence Screener (MEDAS), and 24-h dietary recall. Internal consistency reliability was assessed using Cronbach’s alpha coefficient, while repeatability was examined using the test–retest method. Construct validity was assessed by the MEDAS, and components of the adapted CMDS obtained from the 24-h dietary recall were analyzed using confirmatory factor analysis. The content validity was assessed by the Paired samples t-test and Wilcoxon test. The Bland–Altman test with 95% limits of agreement was used to evaluate the agreement between sum of CMDS. The results were statistically evaluated at a p < 0.05 significance level. Results The content validity index of CMDS was 0.87. The overall Turkish version of CMDS had acceptable internal consistency (Cronbach’s α = 0.853), thus indicating that the score was reliable. The Paired samples t test coefficients between each item and the overall questionnaire ranged from 0.234 to 1.000. A higher intake of olive oil and fish obtained from a 24-h dietary recall was associated with a higher CMDS quartile (p < 0.05). The MEDAS score was correlated with a higher CMDS quartile (p < 0.001). A moderate positive correlation was determined between total CMDS and MEDAS (r = 0.467; p < 0.001). Conclusions Our assessments of the CMDS, consisting of 13 items, in Türkiye demonstrate that it is a viable and reliable instrument to measure adherence to the Mediterranean diet for the adult population. The CMDS is more accurate than other Mediterranean diet scores as it questions about the amount of physical activity and grain products, which helps determine each participant’s eating patterns and general health.

Dairy-derived saturated fats were not associated with risk of type 2 diabetes mellitus and metabolic syndrome: Tehran Lipid and Glucose Study

Zahra Gaeini, Parvin Mirmiran, Sevda Alvirdizadeh et al.

Abstract Emerging evidence indicates that the health effects of saturated fatty acids (SFA) may differ depending on the food source from which they are derived. We aimed to determine the association between dairy-derived SFA and the risk of type 2 diabetes mellitus (T2DM) and metabolic syndrome (MetS). This research was carried out in the Tehran Lipid and Glucose Study, a cohort study of 2256 T2DM-free adults and 1713 MetS-free adults. Adjusted hazard ratios and 95% confidence intervals of T2DM and MetS were calculated in tertile categories of dairy-derived SFA. The risk of T2DM and MetS was estimated through multivariable Cox regression to substitute dairy-derived SFA with other sources of SFA. Participants in the second tertile of dairy-derived SFA had a higher risk of T2DM (HR = 1.59, 95% CI = 1.14–2.21); however, the association did not remain significant in the third tertile (P for trend = 0.082). There were no associations between dairy-derived SFA and the risk of MetS. Substituting dairy-derived SFA for other dietary sources of SFA was not related to the risk of T2DM or MetS. The association between dairy-derived SFA and the risk of T2DM and MetS is still an ongoing research topic. When making dietary choices, it is advisable to consider an overall balanced diet and lifestyle factors.

Co-creating the COMMUNICATE toolkit to support the communication of physical activity messages with adolescents in schools

Caera L. Grady, Elaine Murtagh, Maïté Verloigne et al.

Abstract Background Communication campaigns within multi-component school-based interventions could improve knowledge and awareness about physical activity (PA) behavior. Guidance to implement such communication campaigns is lacking. This paper presents the co-creation and evaluation processes that led to the development of the COMMUNICATE toolkit, which supports implementers to communicate PA messages. Methods Students and teachers from secondary schools enrolled in the Active School Flag (ASF) program were invited to participate. To provide a nuanced perspective on the communication of PA, ASF program implementers (i.e., coordinating teacher and adolescent peer leaders) and receivers (i.e., staff and students not involved in ASF delivery), together known as co-creators, engaged in three rounds of co-creation workshops to share ideas, provide feedback, and refine the toolkit. Workshop data were collected via activity recording sheets; written raw materials were photographed and later transcribed verbatim to generate a dataset. Inductive thematic analysis was conducted to organize and describe the toolkit components. A multi-stakeholder research steering group (n=7) was established to design, facilitate, and evaluate the co-creation process. The toolkit was refined between rounds of workshops. Throughout the co-creation process, the facilitator reflected after each workshop to improve its’ participatory nature. After the final workshop, co-creators completed a process evaluation questionnaire. Additional consultations with experts were held to bridge the gap in expertise. A logic model was developed to understand the theory of change behind the toolkit. Results Eight teachers and 38 students from four ASF schools participated in the co-creation workshops. All 14 aspects of the process evaluation were mainly positive (86.7-100%). Common reasons for negative responses included co-creators not engaging, too much moving around during workshops, teachers’ involvement, and working with strangers. The final version of the toolkit included resources for program implementers to i) raise awareness about PA and the program, ii) plan the promotion of PA, and iii) develop key communication skills. Conclusions The COMMUNICATE toolkit, informed by multi-stakeholder voices, emphasizes a multi-level, multi-stakeholder approach to communicating PA messages with adolescents in schools. It provides tools and resources for program implementers to improve communication efforts. The COMMUNICATE toolkit could be adapted to other peer-led school-based programs.

Case report: nutritional management of a repaired congenital diaphragmatic hernia

S Greyvenstein, RC Dolman-Macleod

Congenital diaphragmatic hernia (CDH) is a rare diaphragm malformation that historically had low survival rates, but advances in care have improved outcomes. This case study discusses the outpatient management of an 8-month-old male infant who survived CDH but, due to a severe oral aversion, required nutritional adaptations to ensure optimal growth was maintained. Barriers experienced included volume tolerance, feeding tolerance, and the need for feeding skill development. The case emphasises the importance of individualised nutritional management.

Lack of iron, zinc, and vitamins as a contributor to the etiology of atopic diseases

D. Peroni, K. Hufnagl, P. Comberiati et al.

Micronutritional deficiencies are common in atopic children suffering from atopic dermatitis, food allergy, rhinitis, and asthma. A lack of iron, in particular, may impact immune activation with prolonged deficiencies of iron, zinc, vitamin A, and vitamin D associated with a Th2 signature, maturation of macrophages and dendritic cells (DCs), and the generation of IgE antibodies. In contrast, the sufficiency of these micronutrients establishes immune resilience, promotion of regulatory cells, and tolerance induction. As micronutritional deficiencies mimic an infection, the body’s innate response is to limit access to these nutrients and also impede their dietary uptake. Here, we summarize our current understanding of the physiological function of iron, zinc, and vitamins A and D in relation to immune cells and the clinical consequences of deficiencies in these important nutrients, especially in the perinatal period. Improved dietary uptake of iron is achieved by vitamin C, vitamin A, and whey compounds, whereas zinc bioavailability improves through citrates and proteins. The addition of oil is essential for the dietary uptake of beta-carotene and vitamin D. As for vitamin D, the major source comes via sun exposure and only a small amount is consumed via diet, which should be factored into clinical nutritional studies. We summarize the prevalence of micronutritional deficiencies of iron, zinc, and vitamins in the pediatric population as well as nutritional intervention studies on atopic diseases with whole food, food components, and micronutrients. Dietary uptake via the lymphatic route seems promising and is associated with a lower atopy risk and symptom amelioration. This review provides useful information for clinical studies and concludes/emphasizes that a healthy, varied diet containing dairy products, fish, nuts, fruits, and vegetables as well as supplementing foods or supplementation with micronutrients as needed is essential to combat the atopic march.

The Role of Nutrients in Reducing the Risk for Noncommunicable Diseases during Aging

M. Bruins, P. van Dael, M. Eggersdorfer

An increasing aging population worldwide accounts for a growing share of noncommunicable diseases (NCDs) of the overall social and economic burden. Dietary and nutritional approaches are of paramount importance in the management of NCDs. As a result, nutrition programs are increasingly integrated into public health policies. At present, programs aimed at reducing the burden of NCDs have focused mostly on the excess of unhealthy nutrient intakes whereas the importance of optimizing adequate essential and semi-essential nutrient intakes and nutrient-rich diets has received less attention. Surveys indicate that nutrient intakes of the aging population are insufficient to optimally support healthy aging. Vitamin and mineral deficiencies in older adults are related to increased risk of NCDs including fatigue, cardiovascular disease, and cognitive and neuromuscular function impairments. Reviewed literature demonstrates that improving intake for certain nutrients may be important in reducing progress of NCDs such as musculoskeletal disorders, dementia, loss of vision, and cardiometabolic diseases during aging. Current knowledge concerning improving individual nutrient intakes to reduce progression of chronic disease is still emerging with varying effect sizes and levels of evidence. Most pronounced benefits of nutrients were found in participants who had low nutrient intake or status at baseline or who had increased genetic and metabolic needs for that nutrient. Authorities should implement ways to optimize essential nutrient intake as an integral part of their strategies to address NCDs.

Food tax policies in Pacific Island Countries and Territories: systematic policy review

Emilee Walby, Amanda C Jones, Moira Smith et al.

Abstract Objective: To systematically identify and review food taxation policy changes in Pacific Island Countries and Territories (PICTs). Design: Food taxation polices, regarding excise taxes and tariffs applied from 2000 to 2020 in twenty-two PICTs, and their key characteristics were reviewed. The search was conducted using databases, government legal repositories and broad-based search engines. Identified documents for screening included legislation, reports, academic literature, news articles and grey literature. Key informants were contacted from each PICT to retrieve further data and confirm results. Results were analysed by narrative synthesis. Setting: Noncommunicable diseases (NCD) are the leading cause of premature death in PICTs and in many jurisdictions globally. An NCD crisis has been declared in the Pacific, and food taxation policy has been recommended to address the dietary risk factors associated with. Progress is unclear. Results: Of the twenty-two PICTs included in the study, fourteen had food taxation policies and five introduced excise taxes. Processed foods, sugar and salt were the main target of excise taxes. A total of eighty-four food taxation policy changes were identified across all food groups. There was a total of 279 taxes identified by food group, of which 85 % were tariffs and 15 % were excise taxes. Individual tax rates varied substantially. The predominant tax design was ad valorem, and this was followed by volumetric. Conclusions: A quarter of PICTs have introduced food excise taxes from 2000 to 2020. Further excise taxes, specifically tiered or nutrient-specific designs, could be introduced and more systematically applied to a broader range of unhealthy foods.

COVID-19: NAD+ deficiency may predispose the aged, obese and type2 diabetics to mortality through its effect on SIRT1 activity

R. Miller, A.R. Wentzel, G. Richards

The SARS-CoV-2 hyperinflammatory response is associated with high mortality. This hypothesis suggests that a deficiency of nicotinamide adenine dinucleotide (NAD+) may be the primary factor related to the SARS-Cov-2 disease spectrum and the risk for mortality, as subclinical nutritional deficiencies may be unmasked by any significant increase in oxidative stress. NAD+ levels decline with age and are also reduced in conditions associated with oxidative stress as occurs with hypertension, diabetes and obesity. These groups have also been observed to have high mortality following infection with COVID-19. Further consumption of NAD+ in a pre-existent depleted state is more likely to cause progression to the hyperinflammatory stage of the disease through its limiting effects on the production of SIRT1. This provides a unifying hypothesis as to why these groups are at high risk of mortality and suggests that nutritional support with NAD+ and SIRT1 activators, could minimise disease severity if administered prophylactically and or therapeutically. The significance of this, if proven, has far-reaching consequences in the management of COVID-19 especially in third world countries, where resources and finances are limited.

Alginate based encapsulation as a tool for the protection of bioactive compounds from aromatic herbs

Alessandra Cristina Tomé, Flávio Alves da Silva

The objective of this study was to evaluate the total phenolic compound content (TPC), antioxidant capacity by the •DPPH, ABTS•+ and FRAP methods in aqueous (AqE), hydroethanolic (HE), and ethanolic (EOH) extracts of six species of aromatic herbs, Basil (Ocimum basilicum), Parsley (Petroselinum crispum), Rosemary (Rosmarinus officinalis), Thyme (Thymus vulgaris), Chervil (Anthriscus cerefolium) and Chive (Allium fistulosum), with subsequent microencapsulation, using the dripping technique, only for the ones who had better TPC contents. The TPC values presented a variation between (142.81±7.06 mg GAE/g) for the HE of rosemary and (30.52±0.95 mg GAE/g) for the HE of chervil. In this study, the lowest antioxidant activity obtained by the •DPPH was for the EOH of parsley, and the highest antioxidant activity was for the HE of rosemary. The best results found by the ABTS•+ was for the HE of rosemary 40.44±0.19 (µmol of Trolox/g), and the lowest values ​​were for the AqE of basil 9.13±0.97 (µmol of Trolox/g), the results obtained in this assay, found higher ferric reducing power for AqE of rosemary 46.78±0.25 (µmol FeSO4/g) and lower value for EOH of chervil 8.99±0.13 (µmol FeSO4/g). The use of scanning electron microscopy revealed the presence of microparticles with the desired shape, sizes ranging from 920.08±11.63 to 754.28±16.62 µm, and encapsulation efficiency, from 68.24±0.15 to 93.39±0.01%. These results indicate that the application of microencapsulated plant extracts has potential for use in the food industry. They present good results for phenolic compounds and antioxidant capacity levels, presenting a good microencapsulation efficiency.

The Epidemiology, Impact, and Diagnosis of Micronutrient Nutritional Dermatoses Part 1: Zinc, Selenium, Copper, Vitamin A, and Vitamin C.

J. Nosewicz, N. Spaccarelli, K. Roberts et al.

Dermatologists play a critical role in diagnosing and managing nutritional deficiencies as they often present with cutaneous findings. Traditionally, nutritional dermatoses are taught in the context of developing countries, famine, population displacement, and poor healthcare access; however, in the United States, common risk factors include chronic liver disease, alcoholism, psychiatric disease, bariatric surgery, inflammatory bowel disease, and hemodialysis. Additionally, nutritional dermatoses may be underdiagnosed in the United States and result in increased morbidity and utilization of hospital resources. There is a need for providers in developed nations to identify these deficiencies, and this review aims to meet that practice gap and provide relevant context to these diseases for dermatologists. This two-part review series will focus on the epidemiology, impact, appearance, and diagnostic modalities for micronutrient deficiencies, including zinc, selenium, copper, and vitamins A and C in part one. The companion review will focus on the B-complex vitamins.
