Ultra-processed food intake is associated with children and adolescents with congenital heart disease clustered by high cardiovascular risk factors.

The excessive intake of ultra-processed foods (UPF) is associated with an increase in cardiovascular risk. However, the effect of UPF intake on cardiovascular health in children and adolescents with congenital heart disease (CHD) is unknown. The aim of the present study was to describe UPF intake and evaluate associations with isolated cardiovascular risk factors and children and adolescents with CHD clustered by cardiovascular risk factors. A cross-sectional study was conducted involving 232 children and adolescents with CHD. Dietary intake was assessed using three 24-hour recalls. UPFs were categorized using the NOVA classification. The cardiovascular risk factors evaluated were central adiposity, elevated high-sensitivity C-reactive protein (hs-CRP) and subclinical atherosclerosis. The clustering of cardiovascular risk factors (waist circumference, hs-CRP and carotid intima-media thickness) was performed, allocating the participants to two groups (high versus low cardiovascular risk). UPFs contributed 40.69% (SD 6.21) to total energy intake. The main UPF groups were ready-to-eat and take-away/fast foods (22.2% energy from UPFs). The multivariable logistic regression revealed that an absolute increase of 10% in UPF intake (OR=1.90; 95% CI: 1.01;3.58) was associated with central adiposity. An absolute increase of 10% in UPF intake (OR=3.77; 95% CI: 1.80;7.87) was also associated with children and adolescents with CHD clustered by high cardiovascular risk after adjusting for confounding factors. Our findings demonstrate that UPF intake should be considered a modifiable risk factor for obesity and its cardiovascular consequences in children and adolescents with CHD.

Dietary patterns are associated with central adiposity and carotid intima-media thickness in children and adolescents with congenital heart disease.

PURPOSE: Unhealthy dietary patterns (DP) in childhood are associated with cardiovascular disease in adulthood. DP in children and adolescents with congenital heart disease (CHD) are unknown. The aims of this study were to describe DPs of children and adolescents with CHD and to evaluate their associations with central adiposity, high-sensitivity C-reactive protein (hs-CRP) and carotid intima-media thickness (cIMT). METHODS: A cross-sectional study including 232 children and adolescents with CHD. Dietary data were based on three 24-h dietary recalls. Central adiposity was evaluated by waist circumference. hs-CRPs were determined by nephelometry. The cIMT was measured using ultrasound. DPs were identified using principal component analysis. Data were examined using logistic and linear regressions. RESULTS: Six DPs were identified. In multivariable-adjusted analysis, unhealthy DP (high intake of poultry, red meat, cold cuts and processed meats, soft drinks and sweetened beverages) and healthy DP (high intake of fish, eggs, bread, beans, tubers and roots, fruit and fruit juice) were associated with increased and decreased odds of central adiposity, respectively (Odds ratio (OR): 2.10; 95% confidence interval (95% CI) 1.09; 4.02; OR: 0.48 95% CI 0.24; 0.93). Besides, low-fat dairy DP (high intake of low-fat milk and dairy, mixed dishes, ultra-processed breads, candy and chocolate) was inversely associated with cIMT (ß: - 0.024; 95% CI - 0.04; - 0.01). CONCLUSION: Unhealthy DP seems to increase the risk of central adiposity, while the healthy DP seems to decrease the risk of central adiposity. Still, low-fat dairy DP was inversely associated with cIMT. These findings may be helpful to develop nutrition recommendations for early cardiovascular disease prevention in children and adolescents with CHD.

Food processing for the improvement of plant proteins digestibility.

Proteins are essential macronutrients for the human diet. They are the primary source of nitrogen and are fundamental for body structure and functions. The plant protein quality (PPQ) refers to the bioavailability, digestibility, and amino acid composition. The digestibility specifies the protein quantity absorbed by an organism relative to the consumed amount and depends on the protein structure, previous processing, and the presence of compounds limiting the digestion. The latter are so-called antinutritional factors (ANF), exemplified by phytates, tannins, trypsin inhibitors, and lectins. Animal proteins are known to have better digestibility than plant proteins due to the presence of ANF in plants. Thus, the inactivation of ANF throughout food processing may increase the PPQ. New food processing, aiming to increase the digestibility of plant proteins, and new sources of proteins are being studied for the animal protein substitution. Here, it is presented the impact of processing on the protein digestibility and reduction of ANF. Several techniques, such as cooking, autoclaving, germination, microwave, irradiation, spray- and freeze-drying, fermentation, and extrusion enhanced the PPQ. The emerging non-thermal technologies impact on protein functionalities but require studies on the protein digestibility. How to accurately determine and how to improve the protein digestibility of a plant source remains a scientific and technological challenge that may be addressed by novel or combining existing processing techniques, as well as by exploring protein-enriched by-products of the food industry.

Phase angle is associated with the physical fitness of HIV-infected children and adolescents.

The objective of this study was to identify the association of phase angle with physical fitness in children and adolescents infected with HIV. Sixty-four children and adolescents infected with HIV (8-15 years old) were tested for vertical transmission. The electrical bioimpedance was used to obtain the phase angle. Body fat (BF) and lean soft tissue mass (LSTM) were measured by x-ray absorptiometry, and the manual grip strength was evaluated by dynamometry. The peak oxygen consumption (VO2 peak) was measured by respiratory change in a submaximal incremental test. Moderate-vigorous physical activity (MVP) and sedentary behavior were measured using accelerometers and were used as covariates. Multiple linear regression was used. The linear correlation analyses demonstrated that the phase angle was inversely proportional to relative BF (r = -0.26), but was not associated with absolute body fat (r = -0.02). The phase angle was directly associated with LSTM (r = 0.57), handgrip strength, and (r = 0.43) peak VO2 (r = 0.55). The phase angle was not associated with absolute BF (ß = -0.017, P = 0.413) and relative (ß = -0.014, P = 0.175). The phase angle presented a direct association with LSTM (ß = 0.041, P = 0.019) and peak VO2 (ß = 0.005; P = 0.019), regardless of age, sex, sexual maturation, MVPA, sedentary behavior, antiretroviral drugs, and viral load. No association was found between phase angle and handgrip strength (ß = 0.153; P = 0.199). It was concluded that phase angle was associated with LSTM and the aerobic fitness in HIV-infected children and adolescents.

Processing effects on the protein quality and functional properties of cold-pressed pumpkin seed meal.

Environmental and food security challenges due to a growing world population may be overcome by using alternative protein sources for the human diet. By-products from edible oil processing industries are potential sources due to their high protein content. Pumpkin seed meals were evaluated regarding proximate composition, in vitro protein digestibility (IVPD), amino acid profile and score, and antinutritional factors. Conventional thermal processing, microwave, and ultrasound treatments impact on samples' nutritional quality were assessed using a central composite experimental design. Raw pumpkin seed meal presented up to 45% protein content and 86% IVPD. Processing increased IVPD up to 96%, with optimized conditions of 87.8 °C, pH8.0, and 37 min, for all processes. Lysine was the only limiting amino acid for raw and processed samples. Phytic acid decreased by 31%, while trypsin inhibitory activity was reduced by 84%. Pumpkin seed by-product is a promising high-quality plant protein source for food formulations.

Agreement Between Body Mass Index and Body Fat in Adolescents With Different Physical Activity Levels.

Purpose: This study aimed to verify the agreement between body mass index (BMI) and body fat in adolescents with different physical activity (PA) levels. Method: This cross-sectional study collected body fat data in 118 adolescents (aged 10 to 14 years) estimated using air-displacement plethysmography (ADP). Body mass 10 and height were used to calculate BMI. Physical activity levels were measured objectively by accelerometers. Results: For boys with low PA, BMI overestimated body fat values measured by ADP (mean error = -0.42; p = .018) which also occurred in group high PA (mean error = -0.76; p = .001). For girls, BMI underestimated body fat values measured by ADP values in group high PA (mean error = 0.43; p = .001) and low PA (mean error = 0.72; p < .001). Conclusion: It is recommended that researchers and practitioners 15 cautiously interpret BMI results, especially considering that most adolescents do not practice enough PA.

Assessment of trace elements in critically ill patients with systemic inflammatory response syndrome: A systematic review.

BACKGROUND: Zinc (Zn), copper (Cu), and selenium (Se) are involved in immune and antioxidant defense. Their role in systemic inflammatory response syndrome (SIRS) treatment and outcomes remains unclear. This systematic review aimed to describe trace element concentrations in different types of biological samples and their relationship with morbidity and mortality in patients with SIRS. METHODS: Literature was systematically reviewed according to the preferred reporting items for systematic reviews and meta-analyses (PRISMA). The search results were screened and evaluated for eligibility, and data were extracted and summarized in tables and figures. RESULTS: Most of the 38 included studies evaluated Se (75%), followed by Zn (42%) and Cu (22%). Plasma was the main biological sample evaluated (58%). Thirteen studies found lower plasma/serum concentrations of Zn, Se, and Cu in SIRS patients than in controls upon admission, 11 studies on adults (intensive care unit-ICU) and two in pediatric ICU (PICU). Three ICU studies found no difference in erythrocyte trace element concentrations in patients with SIRS. In all studies, the two main outcomes investigated were organ failure and mortality. In seven ICU studies, patients with lower plasma or serum Zn/Se levels had higher mortality rates. A study conducted in the PICU reported an association between increased Se variation and lower 28-day mortality. In an ICU study, lower erythrocyte selenium levels were associated with higher ICU/hospital mortality, after adjustment. Five ICU studies associated lower plasma/serum Zn/Se levels with higher organ failure scores and one PICU study showed an association between higher erythrocyte Se levels and lower organ dysfunction scores. CONCLUSION: There was no difference in erythrocyte Se levels in patients with SIRS. Serum/Plasma Zn and serum/plasma/erythrocyte Se are associated with organ dysfunction, mortality, and inflammation. Trace element deficiencies should be diagnosed by erythrocyte, or complementary measurements in the presence of inflammation.

Consumption and Breakfast Patterns in Children and Adolescents with Congenital Heart Disease.

Little is known about skipping breakfast and breakfast patterns (BP) and their evaluation according to sociodemographic, clinical, lifestyle, cardiometabolic and nutritional data in children and adolescents with congenital heart disease (CHD). This cross-sectional study with 232 children and adolescents with CHD identified the prevalence and patterns of the breakfast, described these according to sociodemographic, clinical and lifestyle characteristics, and assessed their association with cardiometabolic and nutritional markers. Breakfast patterns were identified by principal components, and bivariate and linear regression analysis were applied. Breakfast consumption was observed in 73% of participants. Four BP were identified: pattern 1 "milk, ultra-processed bread, and chocolate milk", pattern 2 "margarine and processed bread", pattern 3 "cold meats/sausages, cheeses and butter/cream" and pattern 4 "fruits/fruit juices, breakfast cereals, yogurts, and homemade cakes/pies and sweet snacks". Family history for obesity and acyanotic CHD were associated with breakfast skipping. Younger participants and greater maternal education were associated with greater adherence to pattern 1 and pattern 4. Older participants and longer post-operative time showed greater adherence to pattern 3. No association between skipping breakfast or BP and cardiometabolic and nutritional markers was observed. Nonetheless, the findings reinforce the need for nutritional guidance for healthy breakfast, aiming to reduce the consumption of ultra-processed foods and to prioritize fresh and minimally processed foods.

Nutritional and clinical factors associated with acute kidney injury development in critically ill children.

BACKGROUND: Acute kidney injury (AKI) is common in the pediatric intensive care unit (ICU) and is associated with poorer clinical outcomes. There is scarce data to support an association between nutritional status and nutrient delivery in critically ill pediatric patients. Therefore, the present study aimed to identify the nutritional and clinical factors associated with the development of AKI during pediatric ICU stay. METHODS: This prospective study included critically ill pediatric patients aged < 15 years who were admitted to the medical and surgical pediatric ICU. Clinical, laboratory, nutritional status, nutritional therapy parameters, and AKI data were recorded. Adjusted logistic regression was applied and expressed as odds ratio (OR) and 95% confidence interval (95%CI). P-value < 0.05 was considered significant. RESULTS: We enrolled 108 patients with a median age of 9 months (interquartile range/IQR 2.4-62.5), and 43.5% developed AKI. Sepsis/septic shock (OR 8.00; 95% CI 2.06-32.51, p = 0.003), higher severity of illness (OR 1.89; 95% CI 1.24-2.90, p = 0.003), hypoalbuminemia (OR 4.11; 95% CI 1.61-10.46, p = 0.006), edema (OR 3.42, 95% CI 1.10-10.67, p = 0.034), fluid overload (OR 3.52, 95% CI 1.56-7.96, p = 0.003), need for mechanical ventilation (OR 3.62, 95% CI 1.45-9.04, p = 0.006) and adequate protein intake (OR 0.79, 95% CI 0.63-1.00, p = 0.048) were associated with development of AKI. CONCLUSIONS: Hypoalbuminemia, need for mechanical ventilation, fluid overload, severity of illness, sepsis/septic shock, and edema were risk factors for AKI in pediatric ICU. Furthermore, adequate protein intake is associated with AKI during pediatric ICU stay, making it important to implement nutritional assessment and nutritional therapy protocols for critically ill pediatric patients.

Changes in lifestyle behaviors during the COVID-19 pandemic in children and adolescents with congenital heart disease.

OBJECTIVE: To describe the changes in lifestyle behaviors during the COVID-19 pandemic in children and adolescents with congenital heart disease and to investigate the association of congenital heart disease complexity with lifestyle behavior changes. METHODS: Cross-sectional study with 127 children and adolescents with congenital heart disease, who underwent cardiac procedure (mean postoperative time: 10.11±3.13 years), conducted between December 2020 and January 2021. Lifestyle behaviors, such as dietary intake, physical activity, sedentary behavior, and sleep, were assessed through telephone interview based on validated questionnaires. Dietary patterns were identified using principal component analysis. Frequency of general and specific combinations of healthy and unhealthy lifestyle behavior changes was evaluated. Multinomial logistic regressions were used to test the association between congenital heart disease complexity and changes in lifestyle behavior. RESULTS: The main lifestyle behaviors acquired during pandemic were: 83.5% decreased physical activity; 37.0% increased sedentary behavior; 26.0% slept more than usual; and 23.6% adopted a less-healthy dietary pattern. Almost half of the participants (41.8%) had at least one unhealthy change in lifestyle behavior. Complex congenital heart diseases were associated with increased sedentary behavior (OR 3.49, 95%CI 1.23-9.90). CONCLUSIONS: Children and adolescents with congenital heart disease had unhealthy lifestyle behavior during the pandemic, mainly in the form of reduced physical activity and increased sedentary behavior.

Influence of Emerging Technologies on the Utilization of Plant Proteins.

Protein from plant sources is claimed alternatives to animal sources in the human diet. Suitable protein sources need high protein digestibility and amino acid bioavailability. In terms of protein functionality and food applications, they also need high-quality attributes, such as solubility, gelling, water- and oil-holding capacities, emulsifying, and foaming. Thermal processing can improve the nutritional quality of plants with some disadvantages, like reducing the assimilation of micronutrients (vitamins and minerals). Emerging technologies-such as ultrasound, high-pressure, ohmic heating, microwave, pulsed electric field, cold plasma, and enzymatic processes-can overcome those disadvantages. Recent studies demonstrate their enormous potential to improve protein techno-functional properties, protein quality, and decrease protein allergenicity. However, the literature lacks a broader evaluation, including protein digestibility, industrial-scale optimization, and exploring applications to these alternative protein sources.

Muscular Fitness and Cardiometabolic Variables in Children and Adolescents: A Systematic Review.

BACKGROUND: The importance of muscular fitness (MF) in the performance of activities of daily living is unequivocal. Additionally, emerging evidence has shown MF can reduce cardiometabolic risk in children and adolescents. OBJECTIVES: The purpose of this study was to examine and summarize the evidence regarding the relationship between MF phenotypes (i.e., maximum muscular strength/power, muscular endurance, and maximum muscular strength/power/endurance) and cardiometabolic variables (obesity, blood pressure, lipids, glucose homeostasis, inflammatory markers, and clustered cardiometabolic variables) in children and adolescents. DESIGN: This systematic review was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement and was registered with PROSPERO, number CRD42020179273. DATA SOURCES: A systematic review was performed on five databases (PubMed, EMBASE, SciELO, Scopus, and Web of Knowledge) from database inception to May 2020, with complementary searches in reference lists. ELIGIBILITY CRITERIA FOR SELECTING STUDIES: Eligibility criteria included (1) a study sample of youth aged ≤ 19 years, (2) an assessment of MF with individual or clustered cardiometabolic variables derived from adjusted models (regardless of test/measurement adopted or direction of reported association), and (3) a report of the association between both, using observational studies. Only original articles published in peer-reviewed journals in English, Portuguese, and Spanish languages were considered. The quality of the included studies was assessed by using the National Heart, Lung, and Blood Institute checklist. The percentage of results reporting a statistically significant inverse association between each MF phenotype and cardiometabolic variables was calculated. RESULTS: Of the 23,686 articles initially identified, 96 were included (77 cross-sectional and 19 longitudinal), with data from children and adolescents from 35 countries. The score for the quality of evidence ranged from 0.33 to 0.92 (1.00 maximum). MF assessed by maximum muscular strength/power was inversely associated with lower obesity (64/113 total results (56.6%)) and reduction in clustered cardiometabolic risk (28/48 total results (58.3%)). When assessed by muscular endurance, an inverse association with obesity (30/44 total results (68.1%)) and cardiometabolic risk (5/8 total results (62.5%)) was identified. Most of the results for the relationship between MF phenotypes with blood pressure, lipids, glucose homeostasis, and inflammatory markers indicated a paucity of evidence for these interrelationships (percentage of results below 50.0%). CONCLUSION: MF assessed by maximum muscular strength/power or muscular endurance is potentially associated with lower obesity and lower risk related to clustered cardiometabolic variables in children and adolescents. There is limited support for an inverse association between MF with blood pressure, lipids, glucose homeostasis biomarkers, and inflammatory markers in children and adolescents.

Admission factors associated with nutritional status deterioration and prolonged pediatric intensive care unit stay in critically ill children: PICU-ScREEN multicenter study.

BACKGROUND: Early identification of patients in the pediatric intensive care unit (PICU) at risk of nutritional status (NS) deterioration and poor outcomes is desirable. We aimed to identify factors associated with NS deterioration and prolonged PICU stay. METHODS: Prospective cohort study in eight Brazilian PICUs with children <18 years with a PICU stay >72h. We used multivariable logistic regression to identify the clinical, laboratory, and nutrition variables at admission that were associated with outcomes. NS deterioration was defined as the reduction in weight-for-age, body mass index-for-age or mid-upper arm circumference-for-age z-score ≥1 during PICU stay. Prolonged PICU stay was defined as ≥13 days. RESULTS: We enrolled 363 eligible patients, median age 11.3 months (interquartile range:3.1-45.6) and 46% had at least one complex chronic condition (CCC). NS deterioration was observed in 23% of participants and was associated with CCC (odds ratio [OR]:2.71; 95% confidence interval [CI]:1.44-5.09), after adjusting for severity risk score, leukocyte count, obesity, and PICU site. Prolonged PICU stay was associated with age <2 years (OR:1.95; 95%CI:1.03-3.66), fluid overload (>10%) over the first 72h (OR:2.66; 95%CI:1.50-4.73), and hypoalbuminemia (<3.0 g/dL) (OR:2.05; 95%CI:1.12-3.76), after adjusting for CCC, severity risk score, undernutrition, early nutrition therapy, and PICU site. CONCLUSIONS: CCC at admission was associated with NS deterioration. Age <2 years, fluid overload, and hypoalbuminemia at PICU admission were associated with prolonged PICU stay. These factors must be further evaluated as part of an admission nutrition screening tool for critically ill children.

Systemic oxidative stress in children with cystic fibrosis with bacterial infection including Pseudomonas Aeruginosa.

INTRODUCTION: Oxidative stress (OS) occurs in cystic fibrosis (CF). OBJECTIVE: The objective of this work is to evaluate the influence of bacterial infection on biomarkers of OS (catalase [CAT], glutathione peroxidade [GPx], reduced glutathione [GSH]), markers of oxidative damage (protein carbonyls [PC], thiobarbituric acid reactive substances [TBARS]), together with the nutritional status and lung function in children with CF. METHODS: Cross-sectional study including CF group (CFG, n = 55) and control group (CG, n = 31), median age: 3.89 and 4.62 years, respectively. CFG was distributed into CFG negative bacteriology (CFGB-, n = 27) or CFG positive bacteriology (CFGB+, n = 28), and CFG negative Pseudomonas aeruginosa (CFGPa-, n = 36) or CFG positive Pseudomonas aeruginosa (CFGPa+, n = 19). RESULTS: Compared with CG, CFG (P = .034) and CFGB+ (P = .042) had lower body mass index-for-age z-score; forced expiratory volume in the first second was lower in CFGB+ and CFGPa+ (both P < .001). After adjusting for confounders and compared with CG: CFG showed higher TBARS (P ≤ .001) and PC (P = .048), and lower CAT (P = .004) and GPx (P = .003); the increase in PC levels was observed in CFGB+ (P = .011) and CFGPa+ (P = .001) but not in CFGB- (P = .510) and CFGPa- (P = .460). CONCLUSIONS: These results indicate a systemic OS in children with CF. The presence of bacterial infection particularly Pseudomonas aeruginosa seems to be determinant to exacerbate the oxidative damage to proteins, in which PC may be a useful biomarker of OS in CF.

Moderator role of vitamin D concentrations on the association between metabolic syndrome and C-reactive protein among adults.

OBJECTIVE: To evaluate the association between MetS, its components and insulin resistance (IR) with 25(OH)D and hsCRP. The moderator role of 25(OH)D in the association of MetS, its diagnostic components and IR with hsCRP were also explored. METHODS: A cross-sectional study (2014/2015) with a population-based cohort in Southern Brazil (n = 605). Metabolic syndrome (MetS) diagnosis was defined based on the Joint Interim Statement, while the Homeostasis Model Assessment of insulin resistance (IR) (HOMA-IR) was used for determining IR. Serum concentrations of 25-hydroxy vitamin D [25(OH)D] (ng/mL) and high sensitivity C-reactive protein (hsCRP) (mg/L) were evaluated following standard protocols. 25(OH)D was categorized as sufficiency (>30 ng/mL), insufficiency (20-30 ng/mL) or deficiency (<20 ng/mL) to test its moderator role. Multiple linear regression was used to test the associations. The results were adjusted for possible confounders. RESULTS: Hypertriglyceridemia and IR were associated with lower 25(OH)D concentrations. However, except for systolic blood pressure, other MetS components and IR were associated with higher hsCRP. The association between elevated waist circumference (WC) and hsCRP was moderated by the 25(OH)D concentrations. The hsCRP median concentrations were more than two times higher among those with elevated WC and 25(OH)D insufficiency or deficiency. In this study, inadequate concentrations of 25(OH)D increased the adverse relationship between elevated WC and inflammation. 25(OH)D concentrations could be incorporated into the clinical protocols for monitoring individuals with abdominal obesity to identify those at a higher risk of complications.

Undernutrition at PICU Admission Is Predictor of 60-Day Mortality and PICU Length of Stay in Critically Ill Children.

BACKGROUND: There are few studies that assess the role of different nutritional assessment variables at pediatric intensive care unit (PICU) admission in predicting clinical outcomes. OBJECTIVE: To identify nutritional variables in the first 4 days of PICU stay that predict 60-day mortality and time to discharge alive from the PICU. DESIGN: Single-center prospective study in Southern Brazil, conducted between July 2013 and February 2016. At PICU admission, children with z scores <-2 for body mass index (BMI)-for-age, mid-upper arm circumference (MUAC)-for-age, and triceps skinfold thickness (TSF)-for-age were considered as undernourished. PARTICIPANTS/SETTING: There were 199 patients, aged <15 years, with PICU stay >48 hours. MAIN OUTCOME MEASURES: Sixty-day mortality and time to discharge alive from the PICU. STATISTICAL ANALYSIS PERFORMED: Cox regression model was applied to determine predictors of 60-day mortality and time to discharge alive from the PICU. RESULTS: Median age was 23.1 months (interquartile range=3.9 to 89.1), and 63% were male, with 18% prevalence of undernutrition at admission by BMI-for-age. Median PICU stay was 7 days (interquartile range=4 to 12), and 60-day mortality was 12%. After adjusting for sex, age, Pediatric Index of Mortality 2, and presence of complex chronic conditions, undernutrition based on BMI-for-age (hazard ratio [HR]=3.75; 95% CI=1.41 to 9.95; P=0.008), MUAC-for-age (HR=7.62; 95% CI=2.42 to 23.97; P=0.001), and TSF-for-age (HR=4.01; 95% CI=1.14 to 14.15; P=0.031) was associated with higher risk of 60-day mortality. Based on MUAC-for-age with the same adjustment model, undernourished children had longer time to discharge alive from the PICU (HR=0.45; 95% CI=0.21 to 0.98; P=0.045). CONCLUSIONS: Undernutrition at PICU admission based on different anthropometric variables was predictive of 60-day mortality and longer time to discharge alive from the PICU.

Healthy lifestyle moderates the relationship between cardiovascular disease with blood pressure, body composition, carotid intima-media thickness, and glycated hemoglobin among adults.

We investigate whether the adherence to healthy lifestyle recommendations (regular physical activity, healthy diet, reduced alcohol consumption, nonsmoking) moderates the relationship between cardiovascular disease (CVD) and its risk factors (obesity, diabetes, dyslipidemia, and hypertension) with clinical variables among adults. This cross-sectional population-based study comprised 862 adults (39.3 ± 11.4 years, 46.4% men) from Florianópolis, Brazil. Clinical variables were systolic (SBP) and diastolic blood pressure, waist circumference, body mass index (BMI), percentage of body fat, muscular strength, carotid intima-media thickness (IMT), high sensitive C-reactive protein, and lipid and glucose metabolism markers. Multiple linear regression adjusted for confounding factors was used. Reduced IMT and HbA1c were observed in males with CVD or its risk factors who adopted healthy lifestyle recommendations (p < 0.001), and lower SBP levels were observed in females without CVD or its risk factors (p = 0.034). Females with CVD or its risk factors who followed healthy lifestyle recommendations showed higher BMI (p = 0.035). Adherence to number of healthy lifestyle recommendations moderated cardiovascular health in adults with CVD and without CVD. Novelty The adherence to healthy lifestyle recommendations moderated the relationship between IMT and HbA1c with CVD or its risk factors among males. The lower values of SBP among females without CVD or its risk factors were moderated by the adherence to healthy lifestyle recommendations.

Relationships between high comorbidity index and nutritional parameters in patients with Oropharyngeal Dysphagia.

BACKGROUND & AIMS: Oropharyngeal dysphagia (OD) and comorbidities can exert an influence on nutritional status and contribute to mortality. The aim of the present study was to examine relationships between high Charlson Comorbidity Index (CCI) scores and OD outcomes, including OD severity, feeding route, nutritional status and one-year mortality rate in adults and elderly individuals. METHODS: A longitudinal study, whose the final sample comprised 110 patients with OD and 75 of whom were evaluated for one-year mortality outcome. Swallowing (videofluoroscopy), nutritional status [body mass index (BMI)], CCI, type of feeding route, medications and hospitalization were evaluated. Multinomial logistic regression was performed to calculate the unadjusted and adjusted odds ratios (OR) and 95% confidence intervals (95%CI). RESULTS: Overall sample of the study were adults and elders with a median age (years) of 61.3 [interquartile range (IQR): 58.4-64.2]. The median CCI was 2.3 (IQR: 2.1-2.6) and the mortality rate was 10.8%. Hospitalization was significantly associated with underweight (p = 0.013) and number of medications (p = 0.023). After adjustment, sex/age and nº-Medications/Hospitalization (nº-M/H), CCI ≥3 was associated with nasogastric tube feeding (OR 4.57, 95%CI 1.59-13.1 and OR 3.39, 95%CI 1.21-9.51 respectively) and swallowing performance (OR 0.73, 95%CI 0.59-0.90 and OR 0.74, 95%CI 0.61-0.90 respectively). CONCLUSIONS: A high CCI was associated with OD severity and feeding route, but not with nutritional status or mortality.

The relationship of serum 25-hydroxyvitamin D concentration with clinical variables in patients with oropharyngeal dysphagia.

BACKGROUND & AIMS: The relationship between vitamin D and oropharyngeal dysphagia (OD) is still poorly understood. The aim of this study was to evaluate 25-hydroxyvitamin D [25(OH)D] concentration in patients with OD and to verify its association to nutritional status, functional independence measure (FIM), time of clinical signs (TCS) and OD severity. This is a cross-sectional study conducted with outpatients. Body mass index (BMI), FIM, TCS, causes of OD, comorbidities, penetration-aspiration scale (PAS) and severity scale were evaluated. METHODS: A multiple linear regression and effect size were performed to evaluate the association between serum 25(OH)D concentration and independent variables. RESULTS: Forty-eight participants were included, with a mean age of 60.1 ± 15.3 years. The mean of the 25(OH)D concentration was 26.10 ± 12.0 ng/mL. The prevalence of hypovitaminosis D (<30 ng/mL) was 73%. In the multiple linear regression analysis (adjusted for sex, age, BMI, dietary intake and solar radiation), 25(OH)D concentration was significantly related with the TCS (p = 0.01, f2 = 0.48). Patients with hypovitaminosis D had a moderate effect (p = 0.08, δ = 0.36) for a lower FIM score. CONCLUSIONS: These findings indicate that serum 25(OH)D concentration may be related to the TCS and the functional capacity of patients with OD.

Relationship between oropharyngeal dysphagia, nutritional status, antioxidant vitamins and the inflammatory response in adults and elderly: A cross-sectional study.

BACKGROUND & AIM: Oropharyngeal dysphagia (OD) can lead to a deficiency of antioxidant micronutrients. The aim of the present study was to investigate the relation between OD and nutritional status, antioxidant vitamins (ß-carotene, vitamin E and C) and serum markers of the inflammatory response [C-reactive protein, myeloperoxidase (MPO), nitric oxide metabolites (NOx), tumor necrosis factor-α, interleukin (IL)-1ß and IL-6] in adults and elderly. METHODS: A cross-sectional study was conducted with 69 individuals: 22 in the control group (CG) and 47 in the OD group (ODG). The ODG was subdivided into ODG-mild = normal oral feeding (OF, n = 14), ODG-moderate (OF-modified, n = 22) and ODG-severe (OF-suspended, n = 11). Associations were investigated using multiple linear regression. RESULTS: The body mass index (BMI) was higher in the ODG compared to the CG (p = 0.008), independently of sex, age, energy intake (EI) and score on the Functional Independence Measure. BMI was significantly lower in the ODG-severe compared to the ODG-mild (p = 0.012). OD was associated with lower concentrations of ß-carotene (p < 0.001) and vitamin C (p < 0.001), independently of sex, age and EI, and higher concentrations of MPO (p = 0.008) and NOx (p = 0.011), independently of sex, age and the presence of comorbidities. CONCLUSION: Adults and elderly with OD have lower levels of antioxidant vitamins (ß-carotene and vitamin C) and a high inflammatory response (MPO and NOx). The evaluation of antioxidant vitamins could be incorporated in nutritional status assessment in this population.
