Why should scientists lead? To underpin policy on marine and polar ecosystems

Abstract I recount my personal history, beginning as a young fisherman, becoming an academic fisheries biologist, and ultimately a leader of institutions dedicated to marine and polar research, higher education, and advising policymakers. After my dissertation in the early 1990s, I embarked on an active research career at the Institute of Marine Research (IMR) in Bergen, Norway, developing a sonar method to estimate the abundance of schooling, pelagic fish. My career then transitioned to middle leadership—15 years as Section Leader and Research Director at IMR—followed by >10 years as a top leader for The University Centre in Svalbard, the National Institute of Nutrition and Seafood Research, and finally the Norwegian Polar Institute. I describe the major challenges, opportunities, and processes these leadership roles have entailed. I hope to send a positive message about the influential role of science, and the necessity of clear communication of results and advice at a time when there is a sense of urgency.

Fortifying Micronutrient Supplementation in India: Indian Expert consensus.

Micronutrients play a key role in human health, being involved in energy metabolism, immunity, cellular functioning, growth, and development. Deficiencies in micronutrients occur in individuals of all ages due to several factors, including inadequate diets, disease states, and overweight/obesity. Guidelines from the Indian Council of Medical Research (ICMR) National Institute of Nutrition (NIN) Expert Group on Nutrient Requirements for Indians (2023) have specified the Recommended Dietary Allowances (RDA) for macronutrients and micronutrients. In addition, a healthy diet is crucial for overall health and should be the first step toward addressing micronutrient deficiencies. When diet is inadequate, micronutrient supplements can be provided to compensate. An expert panel of Indian doctors was convened to develop a pathway toward micronutrient supplementation among the Indian population. This Consensus Statement recognizes that different populations have varying needs for specific micronutrients, and ensuring adequate intake of such micronutrients can improve health outcomes. The panel provided recommendations for dietary practices and micronutrient supplementation when diet is inadequate. Addressing micronutrient deficiencies at the primary care level can prevent chronic deficiencies and their consequences. This Consensus Statement can serve as a primer for physicians to monitor and address deficiencies and thus help individuals maintain their health.

Efficacy of a Comprehensive Weight Reduction Intervention in Male Adolescents With Different FTO Genotypes.

The FTO gene polymorphisms may influence the effects of lifestyle interventions on obesity. The present study aimed to assess the influence of the rs9930506 FTO gene polymorphism on the success of a comprehensive weight loss intervention in male adolescents with overweight and obesity. This study was carried out on 96 adolescent boys with overweight and obesity who were randomly assigned to the intervention (n = 53) and control (n = 43) groups. The blood samples of the participants were collected, and the FTO gene was genotyped for the rs9930506 polymorphism. A comprehensive lifestyle intervention including changes in diet and physical activity was performed for 8 weeks in the intervention group. Following the lifestyle intervention, BMI and fat mass decreased significantly in the intervention group compared with the control group (both p < 0.05), while no change was found in weight, height or body muscle percentage between the groups. The participants in the intervention group with the AA/AG genotype and not in carriers of the GG genotype had a significantly higher reduction in BMI (-1.21 vs. 1.87 kg/m2, F = 4.07, p < 0.05) compared with the control group. The intervention in individuals with the AA/AG genotype has been significantly effective in weight loss compared with the control group. The intervention had no association effect on anthropometric indices in adolescents with the GG genotype of the FTO rs9930506 polymorphism.

Технологии машинного обучения при определении факторов, связанных с долей жира в организме Вьетнамских подростков

The aim of this study was to investigate the factors influencing Body Fat Percentage (BFP) among Vietnamese adolescents aged 11 to 15 employing machine learning techniques for predictive analysis. A total of 1,208 adolescents, comprising 598 boys and 610 girls, drawn from nine junior high schools in Vietnam's capital, were enrolled in the study. Body composition measurements were conducted using the HBF 375 (Omron) device by Bioelectrical Impedance Analysis method. The study questionnaire, initially validated by The National Institute of Nutrition, encompassed inquiries related to dietary behaviors, meal frequencies, physical activities, sedentary habits, and nutritional knowledge. A machine learning methodology employing a decision tree algorithm was employed to discern the primary determinants most significantly correlated with BFP. This study successfully identified six distinct predictor groups associated with BFP among adolescents, leveraging the decision tree model, with Root Mean Squared Error (RMSE) and Mean Absolute Error (MAE) values of 4.80 and 3.80, respectively. Among these predictors, frequency of fruit consumption, snacking habits, mode of transportation to school, and screen time (computer and/or cell phone usage) emerged as the most influential factors linked to BFP in adolescents. The combination of these factors and interactions with gender and pubertal status can BFP in Vietnamese adolescents. This research sheds light on the complex and diverse factors impacting BFP in Vietnamese adolescents. This study's results underscore the practical importance of promoting healthy eating and exercise habits among adolescents, offering valuable insights for parents and schools to enhance their childcare strategies.

Assessing the relationship between Body Mass Index and Bone Mineral Density in a clinical-based sample of Vietnamese aged 20–50: A generalized linear regression analysis

BackgroundWhile some evidence has shown that the BMI component differentially influences bone mineral density (BMD), no studies have examined the association between BMI and BMD in Vietnamese adults. The objective of the present study was to examine the associations between BMI and BMD in relatively healthy Vietnamese adults. Demographic data, anthropometric measurements, BMD results measured by DXA and risk factors associated with BMD were retrospectively obtained from the medical records of 333 customers at the National Institute of Nutrition, Vietnam. The customers (aged 20–50 years) underwent a nutrition evaluation and completed BMD examinations between January 1 and November 30, 2021. Osteopenia was defined as the BMD (Z-score) < -2. The correlation between BMI and BMD was analyzed using generalized linear regression. The study found that 7.7% of females and 4.6% of males had osteopenia at the lumbar spine, while 6.9% of females and 5.7% of males had osteopenia at the total hip. Our study discovered a significant relationship between BMI and normal BMD or osteopenia among both males and females, except for the lumbar spine in males. Notably, the results indicated that underweight individuals had a higher likelihood of developing osteopenia. Furthermore, the positive correlation between being overweight or obese and having a higher BMD was also confirmed.Our findings show that the BMI categories affect BMD differently and that being underweight increases the risk of osteopenia among 20-50-year-old Vietnamese. Therefore, we emphasize the need for a BMI-based pre-screening tool for osteopenia in this age group before the further examination.

CONSUMPTION OF HYPERLIPIDEMIC DIET AND WATER INTAKE IN ALBINO RATS TREATED WITH ECLIPTA ALBA – ORIGINAL RESEARCH PAPER

Objective: A high-fat (HF) diet described as higher calories generating from fat instead of carbohydrate or protein. HF usually diets a typical low-carbohydrate diet. Methods: Thirty adult Albino rats of Wistar strain accurately weighing between 165 and 215 g utilized for the present the study. As per CPCSEA guidelines, the protocol was approved by the institutional animal ethical committee no. BMCH/IAEC/01 Anat/2015 dated June 4, 2015. Animals were maintained and fed with standard rat chow, HF diet, and clean drinking water ad libitum, commercially available and manufactured by the National Institute of Nutrition, Hyderabad. Results: Rate of food consumption increased in rats fed with the HF diet for 8 weeks and decreased significantly in rats treated with Eclipta alba for 1, 2, and 3 weeks progressively compared to control group. Water intake increased in the rats fed with an HF diet (43±2.1) compared to rats fed with a normal diet, decreased significantly in the rats treated with E. alba (31±1.4) compared to the HF diet-fed animals. Conclusion: The rate of food consumption increased in rats fed with the HF diet for 8 weeks and decreased significantly in rats treated with E. alba for 1, 2, and 3 weeks progressively compared to control group. Water intake increased in the rats fed with an HF diet compared to rats fed with a normal diet, decreased significantly in the rats treated with E. alba compared to the HF diet-fed animals

Is Obesity a Risk Factor for Iron Deficiency and Anemia? A Pilot Study

Abstract Background The populations suffer from increasing over consumption of food, but continue to have high rates of micronutrient deficiencies. Adipose tissue of obese persons produces increased amount of pro-inflammatory cytokines contributing to the development of a low-grade systemic inflammation in these persons. Objectives To determine the relation between body mass index (BMI) and hemoglobin (Hg) level, serum iron, total iron binding capacity (TIBC) and C reactive protein (CRP). Methodology The study was carried out on 60 women attending the outpatient clinics of the National Nutrition Institute (Egypt). Participants were divided into two groups; 30 obese women (case group) and 30 normal weight women (control group). Diagnosis of obesity was based on BMI &amp;gt;30. Anemia was diagnosed according to Hg level, serum iron and TIBC. Results The mean Hb level of participant women was 11 gm/dl (SD 1.21) and ranged between 8.7 and 13.8 gm/dl. Hb levels showed no significant difference between obese and normal weight women. Serum iron was higher in normal weight women compared with obese women (P &amp;lt; 0.05). No significant correlation was observed between BMI and Hb levels. BMI had a significant negative correlation with serum iron. BMI has significant positive correlations with TIBC and CRP. Linear regression analysis showed a significant association between Hb levels and waist hip ratio. Conclusions High BMI affected negatively levels of serum iron and is associated with inflammatory process as indicated by higher levels of CRP. High waist hip ratio is an important risk factor for anemia.

A comparative study of colored wheat lines across laboratories for validation of their phytochemicals and antioxidant activity

With aim of assessing inter-laboratory variations, phytochemical and antioxidant analysis of seventeen wheat lines were carried out in three well-equipped Indian laboratories viz- National Agri-Food Biotechnology Institute (NABI), Punjab, Central Institute of Post-Harvest Engineering & Technology (CIPHET), Punjab, and National Institute of Nutrition (NIN), Telangana. Protocols were rigorously discussed among laboratories, re-formulated, and uniformly executed for estimating anthocyanins, phenolics, flavonoid content and antioxidant activity measured by colorimetric assays (DPPH, ABTS, FRAP & MC). Compiled data complement each other, with minor inter-laboratory variations. Colored wheat lines show higher antioxidant activity and phytochemical profile than white wheat lines across the laboratories. Within colored wheat lines, black wheat lines have the best nutraceutical profile across the laboratories, with an observed order of black > blue > purple > white. Within black wheat varieties, one of the studied lines, Bk2, consistently outperformed across the laboratories and had highest antioxidant activity, mean anthocyanin content (150.19 mg/kg), phenolic content (277.67 mg/kg), flavonoid content (17.76 mg/kg). The factors that may contribute to the evaluation process include differences in the human resources involved, type and company of solvent, instrument model, and weather and humidity conditions during the measurement. This study validates the higher phytochemicals and antioxidant property of colored wheat through a multi-laboratory analysis.

Prevalence of Overweight and Obesity in Children Diagnosed with Phenylketonuria

Background: Growing evidence suggests a higher occurrence of overweight and obesity in children diagnosed with phenylketonuria (PKU), yet the exact cause is still unknown. Objectives: The objective is to address the prevalence of overweight and obesity in children with PKU. Methods: In our cross-sectional study, we included 47 children with PKU who were receiving care at the nutritional clinic of the National Nutrition Institute. We conducted anthropometric assessments, which involved measuring weight, height, and BMI. Additionally, we performed biochemical evaluations, including measurements of fasting total cholesterol (TC), low-density lipoprotein (LDL) cholesterol, high-density lipoprotein (HDL) cholesterol, very low-density lipoprotein (VLDL) cholesterol, and triglycerides. Moreover, we assessed fasting blood sugar levels. Results: In the study group, 57.44% were males, and 42.55% were females, with no significant gender difference observed. Malnourished children exhibited significantly higher phenylalanine (PHE) levels. Most participants (n = 26, 55.3%) were overweight or obese. A positive and significant correlation (rs = 0.6, P = 0.01) was found between PHE levels and fasting blood sugar levels. Conclusions: Children with PKU have a high prevalence of overweight and obesity, emphasizing the importance of obesity screening in this population.

Evolution of growth charts in India

Growth charts are graphical representations of centile or standard deviation curves prepared from population-based studies. Growth charts are derived from large numbers of children either cross-sectionally or longitudinally. The variation in anthropometric measures amongst individuals of different ethnicities requires specific charts also for Indian children and need to be updated to reflect secular trends. Growth charts in India have come a long way from the development of first ones in the mid-1940s by National Institute of Nutrition (NIN) to Paediatrician Friendly IAP growth charts with mid-parental height and BMI tool. Indian BMI charts recommend overweight and obesity cut-offs for children to the adult equivalents of 23 and 27kg/m2 to prevent the under-diagnosis of obesity. Indian growth charts have been published for upper:lower segment ratios, Turner syndrome, waist circumference, height velocity and sitting height.

NUTRITIONAL STATUS OF THE PATIENTS VISITED THE NUTRITION COUNSELLING CENTER OF VIETNAM NATIONAL INSTITUTE OF NUTRITION

Methods: A cross-sectional study was carried out on 431 patients who visited for nutrition counseling at the Department of Adult Nutrition Consultation, National Institute of Nutrition from May 2021 to April 2022. Nutritional status was classified using criteria for Asians. Results: The rates of chronic energy deficiency, overweight, and obesity were 29.7, 13.5, and 3.7%, respectively. The rates of overweight and obesity were respectively 21.9% and 6.1% in men; and 10.4% and 2.8% in women. The rate of overweight and obesity was higher in men (28%) compared to women (13.2%), while the rate of chronic energy deficiency (CED) was lower in men (22.8%) than that in women (32.2%) (p &lt;0.05). The rate of obesity and CED was highest in the 20-29 age group, then decreased with age. The rates of overweight, obesity and CED were respectively 13.2, 3.7, and 25.4% in city; and 13.8, 3.8, and 37.1% in contryside. Conclusions: The study indicates the alarming rate of obesity and CED in young age group. The similar rate of overweight and obesity in city and contryside while there was significant difference of CED rate between the two regions.

A study on junk food consumption of 1st-year MBBS students aged 19–21 years of batch 2021–22 at Sri Siddhartha Medical College and Hospital, Tumakuru

Background: As per National Institute of Nutrition, Hyderabad, “Junk food is foods containing little or no proteins, vitamins, or minerals but are rich in salt, sugar, fats, and are high in energy (calories).” Many studies show junk foods have an adverse effect on both physical and mental health. Aims and Objectives: This study was taken up to take an insight into the adverse effects of excess calorie consumption during stress which is associated obesity and depression. Materials and Methods: A study on junk food consumption at SSMC, Tumkur to study the relationship between mental and physical health with the consumption of junk food among 1st-year MBBS students. A cross-sectional study was done on 1st-year MBBS students aged 19–21 year at SSMC, Tumkur with the approval of Institutional Ethics Committee. A modified questionnaire was circulated among 150 1st year MBBS students aged 19–21 years at SSMC, Tumkur through Google forms. The data collected were subjected to descriptive statistics and interpreted. Results: About 49% of the participants consumed junk foods regularly with 34% of the participants consuming more than once per week. More than 65% of participants consumed junk food in the evening. Around 46% of participants preferred weekend to consume junk foods. More than 50% of the participants consume junk foods when they are residing in hostel rather than home. More than 70% of the participants prefer junk food consumption during screen time. Conclusion: Factors that have led to consumption of junk food are affordability and cravings. Preference of consumption of carbonated drinks with junk food is also high. The study also shows a strong association of junk food consumption with stress and screen time behavior. Due to its low nutritional value, junk food should be discouraged. Hence, awareness program should be included in to the curriculum of all medical students and in other professions also.

Preliminary assessment of heavy metals intake via food in CKDu affected Uddanam region of Srikakulam, Andhra Pradesh, India

ABSTRACT The present study aimed to assess metal/heavy metal intake by the population via food environment of the Uddanam region, a hotspot for chronic kidney disease of uncertain aetiology (CKDu) in India. The food samples included rice/paddy, marine/freshwater fish, green gram/black gram (whole), and green leafy vegetables (GLVs, i.e. amaranth/spinach). These were analysed for metal/heavy metal (chromium, nickel, copper, arsenic, lead, magnesium, calcium, aluminium, manganese, iron, zinc, barium, cadmium, mercury, and uranium) content using standard procedures. The total heavy metal intake was calculated as a sum of the intake from each food source. The daily dietary intake was compared to safe intake levels (from the Institute of Medicine of the National Academies and National Institute of Nutrition). The intake was higher than safe levels for lead, chromium, and manganese. It is advisable to reduce heavy metal exposure by adopting agricultural practices and public health interventions in terms of diet.

VITAMIN D STATUS IN TUNISIAN OBESE PATIENTS

Objective: Aims: The objectives of this study were to estimate the vitamin D deficiency in obese, identify risk factors for vitamin D deficiency, demonstrating a possible association between vitamin D levels and metabolic parameters. Design and method: This was a transversal study that involved 84 obese adults consultant to the obesity unit in the national institute of nutrition of tunis. Results: The deficit of vitamin D (&lt;30 ng / ml) among obese was 98.8%. Half of them had a rate &lt; 10 ng / ml. We observed a significant relationship between vitamin D levels and the origin of the North West (p = 0,04). Environmental factors involved in vitamin D deficiency are: the veil (p = 0,001), and dietary factors are represented by the calcium intake (p = 0,001) and the daily caloric intake (p = 0,0001). The perc ent of fat mass was negatively related to vitamin D levels (p = 0.01) but not with BMI (p = 0.118) or waist circumference (p = 0,88). Similarly, lipid profile, glucose profile, blood pressure had no link with vitamin D, serum uric acid was positively associated with vitamin D (p = 0.03), as well as the rate of hemoglobin (p = 0,0001). Insulin resistance evaluated by fasting insulin and HOMA-IR were not related to vitamin D levels (p = 0,38 and p = 0,31). Conclusions: At the end of our study, we have identified a very important vitamin D deficiency among obese. Dosage and systematic supplementation should be applied and for that physician awareness is needed.

Formulation and sensory characterization of low-cost, high-energy, nutritious cookies for undernourished adolescents: An approach using linear programming and fuzzy logic

The present study focuses on the development and sensory characterization of low-cost, high-energy, nutritious cookies that satisfy the 30% Recommended Dietary Allowance (RDA) requirement of undernourished adolescents as per the National Institute of Nutrition (NIN), India. The underutilized ingredients finger millet, jackfruit seed powder, moringa powder, soy protein isolate, icing sugar, and oil were optimized using linear programming (LP). The sensory attributes of the developed cookies were compared with imported BP-100 (RUTF biscuit) and two high-energy biscuits available in the market using Fuzzy logic analysis. Cookies with a total energy of 506.81 kcal/100 g, protein 13.46 g/100 g, and fat 25.97 g/100 g were developed at an ingredient cost of US$ 1.52/kg, with the dose of vitamin and mineral premix set at 2.2 g/100 g of cookies. The developed cookies with higher similarity values showed higher consumer acceptability compared to other samples. The texture and taste have the most effect on sensory acceptability and customer approval, following color, overall acceptability, and flavor. Industrial relevanceIn terms of utilizing the locally available ingredients to combat adolescent malnutrition, linear programming, and fuzzy logic are easy methods that can be employed in any World Food Program initiative to formulate low-cost, high-energy food products.

Plasmatic Magnesium Deficiency in 101 Outpatients Living with Type 2 Diabetes Mellitus.

(1) Background: Magnesium deficiency is usually associated with type 2 diabetes mellitus (T2DM). Individuals living with T2DM with hypomagnesemia show a more rapid disease progression and have an increased risk for diabetes complications. (2) Methods: This is a cross-sectional and descriptive study in the National Institute of Nutrition and Food Technology of Tunis in Tunisia, including all adult outpatients (≥18 years old) with a diagnosis of T2DM from 1 September 2018 to 31 August 2019. The aim of this study was to evaluate the prevalence of plasmatic magnesium deficiency in a Tunisian population of T2DM and to study the relationship between magnesium status and intake, glycemic control and long-term diabetes-related complications. (3) Results: Among the 101 T2DM outpatients, 13 (12.9%) presented with a plasmatic magnesium deficiency. The mean age was 56 ± 7.9 years with a female predominance (62%, n = 63). The mean of the plasmatic magnesium level was 0.79 ± 0.11 mmol/L (0.5–1.1), and the mean of 24 h urinary magnesium excretion was 87.8 ± 53.8 mg/24 h [4.8–486.2]. HbA1c was significantly higher in the plasmatic magnesium deficiency group than the normal magnesium status group (10% ± 1.3 vs. 8.3% ± 1.9; p = 0.04), with a significant difference in participants with a poor glycemic control (HbA1c > 7%) (100%, n = 13/13 vs. 53%, n = 47/88; p = 0.001). A weak negative relationship was also found between plasmatic magnesium and HbA1c (r = −0.2, p = 0.03). Peripheral artery disease was more commonly described in individuals with low plasmatic magnesium levels than in individuals with normal levels (39%, n = 5 vs. 0%, n = 0; p < 0.001). The mean plasmatic magnesium level in participants without diabetic nephropathy and also peripheral artery disease was significantly higher compared to individuals with each long-term diabetes-related complication (0.8 mmol/L ± 0.1 vs. 0.71 mmol/L ± 0.07; p = 0.006) and (0.8 mmol/L ± 0.1 vs. 0.6 mmol/L ± 0.08; p < 0.001), respectively. (4) Conclusions: Hypomagnesemia was identified in individuals with T2DM, causing poor glycemic control and contributing to the development and progression of diabetes-related microvascular and macrovascular complications.

Metabolic Syndrome in Type 1 Diabetics: Prevalence and Clinicobiological Features

Background: Because of the world obesity epidemic, some type 1 diabetics exhibit clinical-biological features of metabolic syndrome. Few studies have investigated the association between this syndrome and this type of diabetes. Aim: To estimate the prevalence of metabolic syndrome in type 1 diabetics and to study the relationship between this syndrome and the clinical-biological profile of these patients. Methods: We carried out a cross-sectional study, involving type 1 diabetics, monitored at the National Institute of Nutrition in Tunis. All of these patients underwent a clinical examination and laboratory workup. Results: We included 150 patients. The mean age of the patients was 31.25 ± 10.3 years. Women represented 54% of the patients. Abdominal obesity was found in 61.7% of women and 14.5% of men. The metabolic syndrome was found in 30.7% of patients, with a female predominance (48.1% vs. 10.1% in men, p &lt;0.001). Comparing the two groups with and without metabolic syndrome, the latter was significantly correlated with sedentary lifestyle, daily insulin dose, hypertriglyceridemia, hypoHDL-cholesterolemia and arterial hypertension, but not correlated with the age of the patients, the duration of diabetes or the glycemic control. Conclusion: This work reveals a high prevalence of metabolic syndrome in type 1 diabetics in whom it seems relevant to look for the components of this syndrome, each considered to be a cardiovascular risk factor in its own right.

Predictive Factors of Weight Loss in a Group of Obese Tunisian Women

Aim: The aim of this study was to identify the predictors of a weight loss of more than 5% of the baseline weight in a group of Tunisian women with obesity. Methods: Prospective study at the Obesity Research Unit of the National Institute of Nutrition of Tunis, including 73 adult women with obesity. After 6 months of lifestyle interventions, univariate and multivariate logistic regression analysis were performed to extract predictors of success of weight loss at 6-months. Results: More than half of patients (57.5%) achieved a loss of ≥5% of body weight from baseline. Univariate analysis found that initial weight loss at one month (p &lt;10-3), potassium intake (p=0.010), phosphorus intake (p=0.012) and folate intake (p=0.025) were the factors associated with success of weight loss. The multivariate analysis showed that initial weight loss at one month (OR=2.369; p=0.02), TSH (OR=3.632; p=0.026) and dietary phosphorus intake (OR=0.995; p=0.011) were related to success of weight loss. Conclusion: Larger-scale studies with long-term follow-up would be needed to better determine the predictors not only of success of weight loss but also of its long-term maintenance.
