Assessing daily energy intake in adult women: validity of a food-recognition mobile application compared to doubly labelled water. Front Nutr 2023; 10:1255499. [PMID: 37810925 PMCID: PMC10556674 DOI: 10.3389/fnut.2023.1255499] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/08/2023] [Accepted: 09/04/2023] [Indexed: 10/10/2023] Open
Abstract
Accurate dietary assessment is crucial for nutrition and health research. Traditional methods, such as food records, food frequency questionnaires, and 24-hour dietary recalls (24HR), have limitations, such as the need for trained interviewers, time-consuming procedures, and inaccuracies in estimations. Novel technologies, such as image-based dietary assessment apps, have been developed to overcome these limitations. SNAQ is a novel image-based food-recognition app which, based on computer vision, assesses food type and volume, and provides nutritional information about dietary intake. This cross-sectional observational study aimed to investigate the validity of SNAQ as a dietary assessment tool for measuring energy and macronutrient intake in adult women with normal body weight (n = 30), compared to doubly labeled water (DLW), a reference method for total daily energy expenditure (TDEE). Energy intake was also estimated using a one-day 24HR for direct comparison. Bland-Altman plots, paired difference tests, and Pearson's correlation coefficient were used to assess agreement and relationships between the methods. SNAQ showed a slightly higher agreement (bias = -329.6 kcal/day) with DLW for total daily energy intake (TDEI) compared to 24HR (bias = -543.0 kcal/day). While both SNAQ and 24HR tended to underestimate TDEI, only 24HR significantly differed from DLW in this regard (p < 0.001). There was no significant relationship between estimated TDEI and TDEE using SNAQ (R2 = 27%, p = 0.50) or 24HR (R2 = 34%, p = 0.20) and there were no significant differences in energy and macronutrient intake estimates between SNAQ and 24HR (Δ = 213.4 kcal/day). In conclusion, these results indicate that SNAQ provides a closer representation of energy intake in adult women with normal body weight than 24HR when compared to DLW, but no relationship was found between the energy estimates of DLW and of the two dietary assessment tools. Further research is needed to determine the clinical relevance and support the implementation of SNAQ in research and clinical settings. Clinical trial registration: This study is registered on ClinicalTrials.gov with the unique identifier NCT04600596 (https://clinicaltrials.gov/ct2/show/NCT04600596).

Abstract
BACKGROUND Nutritional intake plays an important role in determining energy availability which is vital to health, wellbeing, and sports performance in an active population. This research assessed the sports undergraduates' nutritional intake compared to the Dietary Guidelines for Americans and nutrition goals provided by WHO. METHODS This study is a quantitative, cross-sectional descriptive study. One hundred and one (n = 101) sports undergraduates aged between 20 to 23 years were recruited and the nutrient intake was assessed using the three-day food diary method and quantified the macro and micronutrients by the food composition database. One sample t-test was performed to compare the mean nutrient intakes with the lowest recommendation values. RESULTS Though most undergraduates were able to meet the dietary requirements in carbohydrates, they were deficient in their protein intake and exceeded in fats intake. Further, both male and female students were deficient in their daily energy intake (1723 kcal, 1607 kcal) and dietary fiber intake (8 g, 11 g). The saturated fat intake was met by all students while 20% of males and 21% of females exceeded the recommendations (< 10%). The micronutrient intake of vitamins such as C, B1, B2, B9, and B12 and minerals such as Calcium, Magnesium, and Potassium, were significantly below the recommendations (p < 0.05) except for vitamin B3 niacin. CONCLUSIONS Providing a nutritionally valuable meal is essentially required to maintain both physical and mental fitness. Our results revealed that the Sri Lankan sport science undergraduates do not have an adequate daily dietary intake of energy, proteins, calcium, magnesium, potassium, and vitamins such as C, B1, B2, B9, and B12.

Abstract
Depression is a common mental disorder that occurs all over the world with treatment resistance commonly seen in clinical practice. Ketamine exhibits an antidepressant that is more often used in the case of treatment-resistant depression (TRD) in MDD and BP. Research emphasizes that a healthy diet and the nutrients it contains can lower the risk of developing depression and form a strategy that supports conventional treatment. The aim of the study was to evaluate the patients’ diet and to analyze the effect of ketamine on food intake among patients with TRD. The study involved 15 patients suffering from treatment-resistant depression and 15 healthy volunteers. The data required for the analysis were collected using the food frequency questionnaire (FFQ) and 4-day food diaries. The study group was statistically significantly less likely to consume milk and plain milk beverages, plain white cheese, wholemeal bread, various vegetables, wine, and drinks. Our results show several disorders in the eating habits of patients with treatment–resistant depression. After the administration of ketamine, the patients consumed significantly less protein, fats, monounsaturated fatty acids (MUFA) and polyunsaturated fatty acids (PUFA), fiber, tryptophan, vitamins, and minerals compared to the control group. There is a lack of research describing the effects of ketamine on nutrition. In order to confirm the results of the study, more participants are required, and the assessment of food diaries filled in at the patient’s home with a longer interval after the last dose of ketamine as well.

Abstract
Background: Understanding trend in nutritional status is crucial to inform national health priorities to improve diets and reduce related diseases. The present study aimed to analyze trends in the concentrations of all measured nutritional biomarkers and their status among US adults across 14 years. Methods: Trends on the concentrations of nutritional biomarkers and nutritional status evaluated by the prevalence of deficiency, inadequacy, excess, and dyslipidemia were analyzed among US adults in 7 cross-sectional National Health and Nutrition Examination Surveys (NHANES 2003–2016) and by age, sex, race/ethnicity, and socioeconomic status. Results: A total of 38,505 participants (weighted mean age of 47.2 years, 51.4% women) were included in the present study. Across 14 years, increased trends were found in red blood cell (RBC) folate, serum vitamin B12, vitamin D and albumin, the prevalence of iodine deficiency, vitamin B6 inadequacy, and hypophosphatemia, whereas decreased trends were observed in serum vitamin E, phosphorus, total calcium, total protein, apolipoprotein B (Apo B), low-density-lipoprotein cholesterol (LDL-C), triglyceride (TG), total cholesterol (TC), blood lead, cadmium, mercury, and the prevalence of vitamin C deficiency, vitamin D inadequacy, iodine excess, and dyslipidemia with elevated LDL-C, TC, TG, and lowered HDL/LDL. Non-Hispanic blacks (NHB) and participants with low socioeconomic status were accounted for the poor nutritional status of most biomarkers compared to their comparts. Conclusion: Most nutritional biomarkers and their status were improved among US adults from 2003 to 2016, but some specific populations should be paid much attention to improve their nutritional status, especially for NHB and participants with low socioeconomic status.

Abstract
PURPOSE We aimed to investigate the relationship between overall nutritional status and cancer mortality. METHODS A total of 12 262 US adults from six consecutive surveys of the National Health and Nutrition Examination Survey (NHANES 2003-2014) were analyzed. The overall health nutritional biomarkers index (HNBI) score, capturing characteristics of 17 biomarkers was developed to assess the overall nutritional status. The lower the HNBI score, the healthier nutritional status would be. Hazard ratio (HR) and 95% confidence intervals (95% CIs) were calculated by Cox proportional hazards regression models to evaluate the association between the HNBI score and cancer mortality. RESULTS The lower overall HNBI score was associated with decreased risk of cancer mortality, compared with participants in the 4th quartile of overall HNBI score, the HR (95% CIs) for participants in the 1st quartiles was 0.54 (0.33-0.89) (P-trend = 0.019). Healthier lifestyle habits and not obesity interacted with HNBI score, compared with participants with higher HNBI score and smoking currently/not exercising regularly/obesity, participants with lower HNBI score and not smoking currently/exercising regularly/not obesity were associated with lower risk of cancer mortality, the HR (95% CIs) were 0.43 (0.26-0.73), 0.57 (0.33-0.97), and 0.62 (0.47-0.97), respectively. These significant associations remained among participants who were followed-up more than 2 years. CONCLUSION Our findings suggested that healthier overall nutritional status was associated with lower risk of cancer mortality among US adults. Not smoking, exercise regularly and not obesity interacted with overall nutritional status. Adherence to better overall nutritional status, lifestyle habits and optimal weight would prevent premature death from cancer.

Abstract
Introduction Degenerative cervical myelopathy (DCM) is the commonest cause of adult spinal cord impairment worldwide, encompassing chronic compression of the spinal cord, neurological disability and diminished quality of life. Evidence on the contribution of environmental factors is sparse; in particular, the role of nutrition in DCM is unknown. The objective of this review was to assess the effect of nutrition on DCM susceptibility, severity and surgical outcome. Methods A systematic review in MEDLINE and Embase was conducted following PRISMA guidelines. Full-text papers in English papers, focussing on cervical myelopathy and nutrition, published before January 2020 were considered eligible. Quality assessments were performed using the GRADE assessment tool. Patient demographics, nutritional factor and DCM outcomes measures were recorded. Relationships between nutritional factors, interventions and disease prognosis were assessed. Results In total, 5835 papers were identified of which 44 were included in the final analysis. DCM patients with pathological weight pre-operatively were more likely to see poorer improvements post-surgically. These patients experienced poorer physical and mental health improvements from surgery compared to normal weight patients and were more likely to suffer from post-operative complications such as infection, DVT, PE and hospital readmissions. Two trials reporting benefits of nutritional supplements were identified, with 1 suggesting Cerebrolysin to be significant in functional improvement. An unbalanced diet, history of alcohol abuse and malnourishment were associated with poorer post-operative outcome. Conclusion Although the overall strength of recommendation is low, current evidence suggests nutrition may have a significant role in optimising surgical outcome in DCM patients. Although it may have a role in onset and severity of DCM, this is a preliminary suggestion. Further work needs to be done on how nutrition is defined and measured, however, the beneficial results from studies with nutritional interventions suggest nutrition could be a treatment target in DCM.

Abstract
OBJECTIVES The aim of this study was to develop and evaluate the validity of a short, culture-specific, semiquantitative food frequency questionnaire (FFQ) for Greek dietary habits and among a population of pregnant women, and to assess the adherence of reported nutritional habits to the Mediterranean diet. METHODS The validity of the FFQ was assessed by comparing FFQ-derived nutrient intakes against the average of two 24-h dietary recalls of 70 pregnant women. We used appropriate statistical methods to examine the nutrient correlation and level of agreement between the two figures (Pearson or Spearman correlation and Bland-Altman test, respectively). Calculation of the Mediterranean Diet Score was performed to evaluate participants' adherence to the Mediterranean diet. RESULTS Statistically significant positive correlations, of medium strength, were observed for almost all macronutrient groups (ρs ranging from 0.326 to 0.538). Dietary fiber intake was the only nutrient where a weak correlation was identified (ρ = -0.106; P > 0.05). Mean intakes, derived from the FFQ, agreed with results from the 24-h recalls based on Bland-Altman analysis, with the agreement ranging between 94.3% and 98.6% for the macronutrient groups under examination. The calculation of the Mediterranean Diet Score revealed that Greek pregnant women's habits are in accordance with the principles of the Mediterranean diet. CONCLUSIONS The developed FFQ is a valid tool that could provide reliable nutrient intake assessment in studies monitoring dietary habits of pregnant women, a group where nutritional monitoring is essential but to date remains limited.

Abstract
BACKGROUND Anorexia nervosa is a serious health condition characterized by a significant low body weight and alteration in body composition components. AIM In the current paper, we aim to summarize the available literature concerning changes in body fat, lean, and bone masses, during anorexia nervosa and after complete weight restoration. METHODS Data were summarized using a narrative approach based on clinical expertise in the interpretation of the available evidence base in the literature. RESULTS The available data revealed three main findings. Firstly, anorexia nervosa causes a significant reduction in body fat mass, however it is completely restored after short-term weight normalization but with a central adiposity phenotype that does not seem to negatively influence treatment outcomes and appears to normalize after 1 year of normal weight maintenance. Secondly, anorexia nervosa causes a significant reduction in bone mineral density, but weight restoration is associated first (≈12 months) with stabilization of bone mineral density, followed by improvements (after ≈16 months); and finally, with complete normalization (after ≈30 months) after normal-weight maintenance. Thirdly, during anorexia nervosa loss of lean and skeletal body mass occurring in particular from the extremities rather than the central regions has been consistently reported, especially in patients with a Body Mass Index (BMI) ≤ 16.5 Kg/m2 however short-term weight restoration is associated with complete normalization. CONCLUSION Anorexia nervosa adversely affects body composition, however this medical complication seems to be reversible through the main treatment strategy of body weight restoration followed by normal weight maintenance, and this should be openly discussed with patients.

Abstract
Elderly patients are at risk of malnutrition and need an appropriate assessment of energy requirements. Predictive equations are widely used to estimate resting energy expenditure (REE). In the study, we conducted a systematic review of REE predictive equations in the elderly population and compared them in an experimental population. Studies involving subjects older than 65 years of age that evaluated the performance of a predictive equation vs. a gold standard were included. The retrieved equations were then tested on a sample of 88 elderly subjects enrolled in an Italian nursing home to evaluate the agreement among the estimated REEs. The agreement was assessed using the intraclass correlation coefficient (ICC). A web application, equationer, was developed to calculate all the estimated REEs according to the available variables. The review identified 68 studies (210 different equations). The agreement among the equations in our sample was higher for equations with fewer parameters, especially those that included body weight, ICC = 0.75 (95% CI = 0.69-0.81). There is great heterogeneity among REE estimates. Such differences should be considered and evaluated when estimates are applied to particularly fragile populations since the results have the potential to impact the patient's overall clinical outcome.

Abstract
Nutrient deficits have been repeatedly linked to cervical human papillomavirus (HPV) persistence, cervical neoplasia, and cervical cancer in case-control studies. This study sought to examine the relationship between overall diet quality and dietary components with the spontaneous resolution of cervical HPV over one year. A prospective observational cohort study was performed. Women with low-grade cervical cytology and/or positive HPV test completed a 24-hour dietary recall, from which the Healthy Eating Index (HEI)-2010, a score of overall diet quality, and scores in dietary categories were calculated. Participants were managed clinically according to national management guidelines. Those whose subsequent testing demonstrated normalization of cytology and/or HPV testing ("HPV resolution") were compared to those whose abnormalities persisted or progressed ("HPV non-resolution"). Twenty-six women were included in the HPV resolution group and 38 in the non-resolution group. They were observed for a median of 428 and 412 day, respectively (p = 0.09). There was no difference in overall diet quality between the groups. Intake of total and whole fruit, and seafood/plant protein were associated with HPV resolution in a logistic regression model (all p < 0.05). These findings could have important implications for the counseling and management of individuals with HPV infection of the cervix.

Validation of a Food Propensity Questionnaire for the Hellenic National Nutrition and Health Survey (HNNHS) and Results on This Population's Adherence to Key Food-Group Nutritional Guidelines. Nutrients 2020; 12:nu12061808. [PMID: 32560456 PMCID: PMC7353208 DOI: 10.3390/nu12061808] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/18/2020] [Revised: 06/05/2020] [Accepted: 06/11/2020] [Indexed: 11/16/2022] Open
Abstract
Background: Food propensity questionnaires (FPQs) are means of dietary assessment in nutritional epidemiology, which provide valuable information for long term intakes and food group consumption. These tools, however, may be subjected to misreporting and need to be validated against standard quantitative methods. Aim: The aim of this study was to examine the validity of the qualitative FPQ developed to assess the dietary habits of the general population in Greece during the Hellenic National Nutrition and Health Survey (HNNHS) and to assess the population’s intake of specific food groups in relation to guidelines. Methods: Validation analysis was based on 3796 [1543 men (42.82%) and 2253 women (57.18%)] participants of the HNNHS in relation to two interviewer-administered 24 h recalls (24 hR). Participants were asked to report the frequency of their dietary intake, using the FPQ provided. Correlations and significance between methods were assessed via Spearman correlation and a Two-sample Wilcoxon rank-sum (Mann-Whitney) test, respectively. Agreement between the FPQ and the 24 hR was performed using the Bland–Altman test and differences between the FPQ’s shown intakes and the recommended intakes by the Dietary Guidelines for Greek Adults were calculated. Results: Medium to weak correlations, but statistically significant (p < 0.05), were observed for most food groups between 24 hR and the FPQ; medium for fruits, dairy products, drinks, and spirits (ranging from ρ = 0.371 to ρ = 0.461; highest for drinks and spirits) and weak for vegetables, meat, fish, eggs, starch foods, sweets, nuts, fats and oils, and fast food (ρ = 0.111 to ρ = 0.290; lowest for starch foods). A non-significant correlation was found for legumes (ρ = 0.070). The mean intake agreement (Bland–Altman analysis) between the FPQ and the 24 hR was 96.08% and ranged from 94.43 to 99.34% for the 14 food groups under examination. When food group intakes were compared to guidelines, results showed that the population’s dietary intake was below the guidelines for fruits, vegetables, whole grains, fish, and legumes. On the other hand, it was above the guidelines for most of the “unhealthy” food groups, in particular, fast food, sweets, drinks and spirits, red meat, and sweets. Conclusions: The specific FPQ provides valid information on major food groups and can be used to examine long term dietary patterns in nutritional studies. Ιn addition, dietary intakes of Greek adults are problematic and initiatives at the public health level are necessary.

Abstract
Adequate and appropriate nutrition is essential for growth and development in children; all put at risk in those with cancer. Overnutrition and undernutrition at diagnosis raise the risk of increased morbidity and mortality during therapy and beyond. All treatment modalities can jeopardize nutritional status with potentially adverse effects on clinical outcomes. Accurate assessment of nutritional status and nutrient balance is essential, with remedial interventions delivered promptly when required. Children with cancer in low- and middle-income countries (LMICs) are especially disadvantaged with concomitant challenges in the provision of nutritional support. Cost-effective advances in the form of ready-to-use therapeutic foods (RUTF) may offer solutions. Studies in LMICs have defined a critical role for the gut microbiome in the causation of undernutrition in children and have demonstrated a beneficial effect of selected RUTF in redressing the imbalanced microbiota and improving nutritional status. Challenges in high-income countries relate both to concerns about the potential disadvantage of preexisting obesity in those newly diagnosed and to undernutrition identified at diagnosis and during treatment. Much remains to be understood but the prospects are bright for offsetting malnutrition in children with cancer, resulting in enhanced opportunity for healthy survival.

Does Eating Addiction Favor a More Varied Diet or Contribute to Obesity?-The Case of Polish Adults. Nutrients 2020; 12:nu12051304.

Abstract
The rapidly increasing prevalence of overweight and obesity indicates a need to search for their main causes. Addictive-like eating and associated eating patterns might result in overconsumption, leading to weight gain. The aim of the study was to identify the main determinants of food intake variety (FIV) within eating addiction (EA), other lifestyle components, and sociodemographic characteristics. The data for the study were collected from a sample of 898 Polish adults through a cross-sectional survey in 2019. The questionnaire used in the study included Food Intake Variety Questionnaire (FIVeQ), Eating Preoccupation Scale (EPS), and questions regarding lifestyle and sociodemographic factors. High eating addiction was found in more than half of the people with obesity (54.2%). In the study sample, physical activity at leisure time explained FIV in the greatest manner, followed by the EPS factor: eating to provide pleasure and mood improvement. In the group of people with obesity, the score for this EPS factor was the best predictor of FIV, in that a higher score was conducive to a greater variety of food intake. Sociodemographic characteristics differentiated FIV only within groups with normal body weight (age) and with overweight (education). In conclusion, food intake variety (FIV) was associated with physical activity at leisure time, and then with EPS factor “Eating to provide pleasure and mood improvement”, whereas sociodemographic characteristics were predictors of FIV only within groups identified by body mass index (BMI). Nevertheless, our observations regarding the eating to provide pleasure and mood improvement factor and its associations with food intake variety indicate a need for further research in this area. Future studies should also use other tools to explicitly explain this correlation.

Abstract
BACKGROUND AND OBJECTIVES This study assessed the nutritional status among householders in urban South Tarawa and rural Butaritari in Kiribati. METHODS AND STUDY DESIGN In this cross-sectional study, we assessed energy and nutrient intakes, food variety scores, and dietary diversity scores of men and women from 468 households randomly selected in South Tarawa (n = 161) and Butaritari (n = 307) using a 24-hour dietary recall. Nutrient adequacy ratios and mean adequacy ratios of selected nutrients were also determined from 3-day weighed food records collected among participants living in a further 28 households from South Tarawa (n = 29) and Butaritari (n = 44). RESULTS Based on the 24-hour dietary recall, the average energy intake for men and women was 2536 kcals and 2068 kcals, respectively. Carbohydrate (CHO), fat, and protein intakes for men and women were 332.5 g, 76.5 g, and 130.4 g and 291.7 g, 55.1 g, and 103.5 g, respectively. The mean and standard deviation of household Food Variety Score and Dietary Diversity Score was 3.90 ± 1.25 and 5.44 ± 1.92, respectively. Intakes of vitamin A, calcium, and iron, and zinc were notably deficient in both locations, with the urban participants having lower intakes of vitamin B-1, vitamin B-2, magnesium, and potassium than their rural counterparts. Mean sodium intakes exceeded recommendations for all age groups in South Tarawa except children aged 4 to 6 years. CONCLUSIONS Food consumption patterns of the households in South Tarawa and Butaritari reflected high consumption of nontraditional diets and refined foods, which manifested in inadequate micronutrient intake estimates and low dietary diversity: strong risk factors for noncommunicable diseases such as obesity and diabetes.

Abstract
Comprehensive nutritional assessment is the basis of nutritional diagnosis and necessary to identify the individual or the population at a risk of dietary deficiencies. However, there is no specific and confirmatory method to measure nutritional status. Present study tried to find out the efficacy of two nutritional assessment method (1) biochemical test like Total serum protein (TSP) and (2) anthropological measurements like body mass index (BMI) and mid-upper-arm-circumference (MUAC). Later, three methods were tested and compared for the strength of assessing the nutritional status. Study was conducted among 198 adult Oraon, 84 male, 114 female individuals of Madarihat and Falakata police station area, Alipurduar district, West Bengal. Selected blood parameters such as total serum protein (TSP), serum albumin and haemoglobin and anthropometric measurements (height, weight, mid-upper arm circumference, waist circumference, hip circumference, calf circumference, biceps skinfold, triceps skinfold, and calf skinfold) were obtained following standard instruments and protocols. Nutritional status of all individuals was assessed by TSP, BMI and MUAC classification methods. Comparison between/among three classification methods (TSP, BMI and MUAC) was done and discriminant function analysis was adopted to find out the percentage of correct classification by each methods. It was found that prevalence of undernutrition using TSP classification was 38.1% male and 43.0% female; using BMI was 34.5% male and 53.5% female; using MUAC was 45.2% male and 64.9% female. Discriminant function analysis showed that BMI (97.0%) had the highest capability of correct classification followed by MUAC (84.80%) and TSP (63.60%). Results indicate that however, TSP is an objective way of nutritional assessment, but BMI had the highest capability of correct classification of nutritional status. It may be pointed out that the evaluation with TSP was expensive and invasive whereas BMI is non-expensive and completely a non-invasive way of evaluation. Therefore, BMI may widely be used for nutritional assessment.

Identifying sources of measurement error in assessing dietary intakes - Results of a multi-country ring-trial. Nutr Metab Cardiovasc Dis 2019; 29:127-134.

Abstract
BACKGROUND AND AIMS Epidemiological investigations include dietary intakes as primary exposures or potential confounders. To reduce bias, data collection protocols include the administration of questionnaires together with measurements of biomarkers. Some error, however, remains and needs to be considered in the analysis and interpretation of results. The European Food Safety Authority supported a ring-trial to compare the precision and reproducibility of dietary assessment methods applied in Europe. METHODS AND RESULTS Software applications used to collect 24-hour recalls and food records in six countries (Estonia, Italy, Latvia, Portugal, Spain, and Sweden) were assessed. The intake of 256 foods was identically reported to each method. Experienced interviewers participated and were instructed to repeat national protocols closely. The error in recording quantities, compared with reference values, was variable but in about 60% of recorded quantities was in the range of ±20%. Errors were however unsystematic and independent of the food type or quantification method used - although food pictures performed better. The reproducibility of some tools was limited. The methods generally captured additional ingredients (usually flavoring agents), but not sweetening agents or fortification and failed to record packaging information in about 60% of the cases. CONCLUSION In a design that eliminated respondent bias, this study indicates that softwares, supporting databases and interviewers generally introduce random error in dietary assessments. The inclusion of large sample sizes and food pictures to quantify portions, together with enhanced attention on interviewers' training, standardisation of procedures and regular tool upgrades are essential in assuring a study's quality and comparability.

Sex-Specific Associations of Blood-Based Nutrient Profiling With Body Composition in the Elderly. Front Physiol 2019; 9:1935.

Abstract
The intake of adequate amounts and types of nutrients is key for sustaining health and a good quality of life, particularly in the elderly population. There is considerable evidence suggesting that physiological changes related to age and sex modify nutritional needs, and this may be related to age-associated changes in body composition (BC), specifically in lean and fat body mass. However, there is a clear lack of understanding about the association of nutrients in blood and BC parameters in the elderly. This study investigated the relationships among blood nutrients (amino acids, fatty acids, major elements, trace-elements, and vitamins), BC and nutrient intake in a population of 176 healthy male and female Italian adults between the ages of 65 and 79 years. 89 blood markers, 77 BC parameters and dietary intake were evaluated. Multivariate data analysis was applied to infer relationships between datasets. As expected, the major variability between BC and the blood nutrient profile (BNP) observed was related to sex. Aside from clear sex-specific differences in BC, female subjects had higher BNP levels of copper, copper-to-zinc ratio, phosphorous and holotranscobalamin II and lower concentrations of branched-chain amino acids (BCAAs) and proline. Fat mass, percentage of fat mass, percentage of lean mass and the skeletal muscle index (SMI) correlated the most with BNP in both sexes. Our data showed positive correlations in male subjects among ethanolamine, glycine, albumin, and sulfur with SMI, while palmitoleic acid and oleic acid exhibited negative correlations. This differed in female subjects, where SMI was positively associated with albumin, folic acid and sulfur, while CRP, proline and cis-8,11,14-eicosatrienoic acid were negatively correlated. We investigated the influence of diet on the observed BNP and BC correlations. Intriguingly, most of the components of the BNP, except for folate, did not exhibit a correlation with nutrient intake data. An understanding of the physiological and biochemical processes underpinning the observed sex-specific correlations between BNP and BC could help in identifying nutritional strategies to manage BC-changes in aging. This would contribute to a deeper understanding of aging-associated nutritional needs with the aim of helping the elderly population to maintain metabolic health.

Abstract
Objectives Choosing an optimal amputation level requires balance between maximizing limb salvage while minimizing chances of non-healing wounds and re-amputation. Our aim was to assess the long-term outcome for minor amputations in patients with peripheral vascular disease. Methods A retrospective study of minor amputations between January 1, 2005 and December 31, 2015 was performed. Electronic medical records of eligible patients were examined to extract demographics, co morbidities and clinical data. Results Within the study period, 220 patients underwent 296 primary minor amputations in 244 lower extremities. Wound healing was achieved in 18.2% (54 of 296 amputations) and 43.6% (129 of 296 amputations) at 90 days and 365 days, respectively. Rates of progression to major amputation were 16.4% (40 or 244 limbs) and 21.7% (53 of 244 limbs) at 90 days and 365 days, respectively. In the final multivariate model, lower ipsilateral posterior tibial waveforms predicted poor 90-day healing (OR = 2.22, p = 0.01) as well as limb loss (OR = 3.02, p = 0.02) in a dose-response manner. In the final logistic regression model, emergency department admission (OR = 0.20, p < 0.01), ipsilateral posterior tibial waveform (OR = 2.63, p < 0.01), and post-operative infection (OR = 0.30, p < 0.01) were predictors of poor healing status at study endpoint. Conclusion This study shows that a majority of foot amputees require ongoing care for non-healing wounds and a proportion necessitate conversion to major amputation. Adequate vascularization is essential to promote and maintain healing.

Abstract
Thiamin, riboflavin, niacin, and vitamin B₆ are essential micronutrients that are mainly involved in energy metabolism; they may prevent the occurrence of developmental abnormalities and chronic degenerative and neoplastic diseases. The aim was to analyze dietary intake and food sources of those four nutrients in subjects (n = 2009) aged 9⁻75 years old from the Spanish ANIBES (Anthropometry, Intake, and Energy Balance in Spain) study. Dietary data were collected by means of a validated, photo-based three-day dietary food record. Underreporting was analysed according to the European Food and Safety Authority (EFSA, Parma, Italy) protocol. Mean (max⁻min) reported intake for the whole population of thiamin was 1.17 ± 0.02 mg/day, (0.30⁻3.44 mg/day), riboflavin 1.44 ± 0.02 mg/day, (0.37⁻3.54 mg/day), niacin 29.1 ± 0.2 mg/day (6.7⁻109 mg/day), and vitamin B₆ 1.54 ± 0.01 mg/day (0.28⁻9.30 mg/day). The main sources of intake for thiamin, niacin, and vitamin B₆ were meat and meat products, and for riboflavin were milk and dairy products. An elevated percentage of the Spanish ANIBES population meets the EFSA recommended intakes for thiamin (71.2%), riboflavin (72.0%), niacin (99.0%), and vitamin B₆ (77.2%).

Household food insecurity access scale and dietary diversity score as a proxy indicator of nutritional status among people living with HIV/AIDS, Bahir Dar, Ethiopia, 2017. PLoS One 2018; 13:e0199511. [PMID: 29953457 PMCID: PMC6023122 DOI: 10.1371/journal.pone.0199511] [Citation(s) in RCA: 18] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/01/2018] [Accepted: 06/09/2018] [Indexed: 12/29/2022] Open
Abstract
Background Both household food insecurity and household dietary diversity have been found reliable in describing the dietary intake of a population. However, it had not been proven as reliable instrument for assessing nutritional status of individuals in a clinical context. There has been a need for evidence on the validity of using proxy and easy dietary indicators for nutritional status. Method A facility based cross sectional study design was employed on 423 people with HIV infection visiting all ART clinics in Bahir Dar, North Ethiopia. Nutritional status was determined by computing BMI. Food insecurity was assessed using household food insecurity access scale. Dietary diversity was measured using a tool adopted from Food and Nutrition Technical Assistance Project. Data were entered to Epidata version 3.1and analyzed by SPSS version 20. Reliability analysis, sensitivity and specificity analysis were determined. Result The sensitivity of the household food insecurity access scale and dietary diversity score was 87.9% and 79.8%, respectively, while their specificity was 56.2% and 70.2%. The AUC at 95% CI for the household food insecurity access scale and household dietary diversity score were 73.4 (68.4–78.4) and 73.1 (68.1–78.2) while their cut of point that maximized their sensitivity and specificity was 1 and 6 respectively. Household food insecurity access scale and household dietary diversity score were found to be reliable tools with a Cronbach’s Alpha of 0.926 and 0.799, respectively. Conclusion In assessing under nutrition among PLHIV especially in limited resource settings, both the household food insecurity access scale and household dietary diversity score were found valid and reliable proxy indicators for measuring nutritional status.

Bariatric patients' nutritional status as a risk factor for postoperative complications, prolonged length of hospital stay and hospital readmission: A retrospective cohort study. Int J Surg 2018; 56:210-214. [PMID: 29933099 DOI: 10.1016/j.ijsu.2018.06.022] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/08/2017] [Revised: 05/21/2018] [Accepted: 06/16/2018] [Indexed: 02/07/2023]
Abstract
BACKGROUND The prevalence of obesity is growing worldwide. Malnutrition has been identified as a risk factor, leading to higher morbidity rate and prolonged length of hospital. So far there are no high quality data on the impact of malnutrition on length of hospital stay and morbidity regarding bariatric surgery. The aim of the study was to assess association between nutritional status and outcomes bariatric surgeries. MATERIAL AND METHODS The study was a prospective observational study. INCLUSION CRITERIA informed consent to participate in the study, age 18-65 years, meeting the eligibility criteria for bariatric treatment, qualification for laparoscopic sleeve gastrectomy (LSG) or laparoscopic Roux-en-Y Gastric By-pass (LRYGB). EXCLUSION CRITERIA revision surgery, lack of necessary data. The primary endpoint was the evaluation of protein malnutrition risk prevalence. Secondary: influence of malnutrition risk patients' on treatment course and postoperative complications. RESULTS 533 patients met inclusion criteria and were analyzed. 169 patients (32%) had qualitative risk of malnutrition. The body mass index (BMI) was significantly higher in malnutritioned group, p = 0.001. Albumins in malnutritioned group was 38 g/l (IQR 35-42), whereas in control group it was 41 g/l (IQR 39-43), p = 0.027. Lymphocyte count in malnutrition risk group and control group were 1.24 10'3/μl (IQR 1.1-1.37) and 1.94 10'3/μl (IQR1.7-2.3) respectively, p < 0.001. In linear regression model, a correlation between BMI and total number of lymphocytes was present, p < 0.001. Malnutrition risk did not affect the total morbidity rate. There was a difference in occurrence of postoperative nausea and vomiting, p = 0.033. CONCLUSIONS Higher BMI is associated with greater risk of malnutrition. Proper perioperative care may diminish the impact of malnutrition on adverse effects and length of stay (LOS).

Abstract
BACKGROUND Detailed information on global individual-level consumption patterns is imperative for informed policy making. However, such data are dispersed and incomplete. OBJECTIVE To review and discuss the methodologies, observed data availability, challenges, and opportunities pertaining to global dietary surveillance. METHODS This investigation provides an extensive review of global dietary assessment methodologies and challenges, including at the survey level, the dietary collection and assessment level, and the dietary data processing and analysis level. The focus is on nationally representative individual-level data, and additional types of dietary data, such as dietary biomarkers, household assessment, and food availability, are reviewed as alternatives. Practical guidance is provided to inform key decisions when designing dietary surveys and collecting, analyzing, and using dietary data. This article further identifies and describes existing global and regional dietary initiatives/data sets. RESULTS Harmonized and standardized primary individual-level dietary data collection, processing, and analysis worldwide are currently not available. Evaluation and decision-making should be based on best available data, that is, secondary nonharmonized yet to the extent possible, standardized individual-level dietary data. Existing initiatives differ substantially in methodologies, including survey design/representativeness, coverage, diet assessment, and dietary metric standardization and processing. Data gaps have been identified that were more profound for certain countries, certain dietary indicators across countries, population subgroups, representativeness, or time periods. CONCLUSIONS Optimizing worldwide dietary habits to improve population health requires systematically identified and evaluated data on a continuing basis. Leveraging existing available dietary data and efforts is an indispensable prerequisite for informed priority setting targeting the intersections between diet and disease.

Abstract
The use of biomarkers constitutes an essential tool to assess the bioavailability of carotenoids in humans. The present article aims to review several methodological, host-related and modulating factors relevant on assessing and interpreting carotenoid bioavailability. Markers for carotenoid bioavailability can be broadly divided into direct, biochemical or "analytical" markers and indirect, physiological or "functional" indicators. Analytical markers usually refer to biochemical indicators of intake and/or status (short and long term exposure) while functional measures may be interpreted in terms of cumulative exposure, biological effect (bioactivity) or modification of risk factors. Both types of markers display advantages and limitations but, in general, a relationship exists among the type of marker, the biological specimen needed and the time required for a change. Humans may absorb a wide range of carotenes and xanthophylls and many of them may be found in serum and tissues. However, under physiological conditions, the several classes of dietary carotenoids may behave unequally leading to a different systemic profile and, moreover, they can be selectively accumulated at target tissues. In addition, some carotenoids may be chemically and enzymatically modified generating different oxidative metabolites and apocarotenoids. Quantitatively, the biological response upon carotenoid intervention (assessed by analytical and functional markers) is highly variable but the use of large doses and long-term protocols may lead to saturation effects and the loss of linearity in the response. Also, despite carotenoid exposition is considered to be safe, markers of overexposure include clinical signs (i.e. carotenodermia, corneal rings and retinopathy) and biochemical indicators (hypercarotenemia, xanthophyll esters). Overall, both host-related and methodological factors may influence analytical and functional markers to assess carotenoid bioavailability although the different subclasses of carotenoids may not be equally affected.

Abstract
For the past 45 y, the National Center for Health Statistics at the CDC has carried out nutrition surveillance of the US population by collecting anthropometric, dietary intake, and nutritional biomarker data, the latter being the focus of this publication. The earliest biomarker testing assessed iron and vitamin A status. With time, a broad spectrum of water- and fat-soluble vitamins was added and biomarkers for other types of nutrients (e.g., fatty acids) and bioactive dietary compounds (e.g., phytoestrogens) were included in NHANES. The cross-sectional survey is flexible in design, and biomarkers may be measured for a short period of time or rotated in and out of surveys depending on scientific needs. Maintaining high-quality laboratory measurements over extended periods of time such that trends in status can be reliably assessed is a major goal of the testing laboratories. Physicians, health scientists, and policy makers rely on the NHANES reference data to compare the nutritional status of population groups, to assess the impact of various interventions, and to explore associations between nutritional status and health promotion or disease prevention. Focusing on the continuous NHANES, which started in 1999, this review uses a "lessons learned" approach to present a series of challenges that are relevant to researchers measuring biomarkers in NHANES and beyond. Some of those challenges are the use of multiple related biomarkers instead of a single biomarker for a specific nutrient (e.g., folate, vitamin B-12, iron), adhering to special needs for specimen collection and handling to ensure optimum specimen quality (e.g., vitamin C, folate, homocysteine, iodine, polyunsaturated fatty acids), the retrospective use of long-term quality-control data to correct for assay shifts (e.g., vitamin D, vitamin B-12), and the proper planning for and interpretation of crossover studies to adjust for systematic method changes (e.g., folate, vitamin D, ferritin).

Abstract
Background Obesity is a consequence of chronic energy imbalance. We need accurate and precise measurements of energy intake and expenditure, as well as the related behaviors, to fully understand how energy homeostasis is regulated in order to develop interventions and evaluate their effectiveness to combat the global obesity epidemic. Scope of review We provide an in-depth review of the methodologies currently used to measure energy intake and expenditure in humans, including their principles, advantages, and limitations in the clinical research setting. The aim is to provide researchers with a comprehensive guide to conduct obesity research of the highest possible quality. Major conclusions An array of methodologies is available to measure various aspects of energy metabolism and none is perfect under all circumstances. The choice of methods should be specific to particular research questions with practicality and quality of data the priorities for consideration. A combination of complementary measurements may be preferable. There is an imperative need to develop new methodologies to improve the accuracy and precision of energy intake assessments. Image-based technology is a significant step to improve energy intake measurement. Physical activity informs patterns but not absolute energy expenditure. Combining complementary measurements overcomes shortfalls of individual methods.

Abstract
Nutritional cognitive neuroscience is an emerging interdisciplinary field of research that seeks to understand nutrition's impact on cognition and brain health across the life span. Research in this burgeoning field demonstrates that many aspects of nutrition—from entire diets to specific nutrients—affect brain structure and function, and therefore have profound implications for understanding the nature of healthy brain aging. The aim of this Focused Review is to examine recent advances in nutritional cognitive neuroscience, with an emphasis on methods that enable discovery of nutrient biomarkers that predict healthy brain aging. We propose an integrative framework that calls for the synthesis of research in nutritional epidemiology and cognitive neuroscience, incorporating: (i) methods for the precise characterization of nutritional health based on the analysis of nutrient biomarker patterns (NBPs), along with (ii) modern indices of brain health derived from high-resolution magnetic resonance imaging (MRI). By integrating cutting-edge techniques from nutritional epidemiology and cognitive neuroscience, nutritional cognitive neuroscience will continue to advance our understanding of the beneficial effects of nutrition on the aging brain and establish effective nutritional interventions to promote healthy brain aging.

Abstract
A workshop organized by the University Medical Center Groningen addressed various current issues regarding nutrient status of individuals and populations, tools and strategies for its assessment, and opportunities to intervene. The importance of nutrient deficiencies and information on nutrient status for health has been illustrated, in particular for elderly and specific patient groups. The nutrient profile of individuals can be connected to phenotypes, like hypertension or obesity, as well as to socio-economic data. This approach provides information on the relationship between nutrition (nutrient intake and status) and health outcomes and, for instance, allows us to use the findings to communicate and advocate a healthy lifestyle. Nutrition is complex: a broader profile of nutrients should be considered rather than focusing solely on a single nutrient. Evaluating food patterns instead of intake of individual nutrients provides better insight into relationships between nutrition and health and disease. This approach would allow us to provide feedback to individuals about their status and ways to improve their nutritional habits. In addition, it would provide tools for scientists and health authorities to update and develop public health recommendations.
