RESUMO

The coronavirus disease 2019 (COVID-19) pandemic has caused widespread devastation, with millions of confirmed cases and deaths worldwide. Although there were efforts made to develop treatments and vaccines for COVID-19, the coexistence of sarcopenia, a muscle disorder, has been largely overlooked. It is while new variants of this disease (eg, BA.2.86) are challenging the current protocols. Sarcopenia is associated with increased mortality and disability, and shares common mechanisms with COVID-19, such as inflammation, hormonal changes, and malnutrition. This can worsen the effects of both conditions. Furthermore, survived patients with COVID-19 who have elevated risk, as well as aging, which increases the process of sarcopenia. Therefore, addressing sarcopenia in patients with COVID-19 and surviving individuals can be crucial for improving outcomes and preventing long-term disability. During hospital stays, assessing sarcopenia through indicators like muscle wasting and malnutrition is important. Nutritional interventions, such as malnutrition screening and enteral feeding, play a critical role in preventing sarcopenia in hospitals. Mental health and physical activity evaluations and interventions are also necessary. Even after recovering from COVID-19, there is a risk of developing sarcopenia, requiring continued monitoring. Nutrition and physical activity considerations are vital for prevention and management, necessitating tailored training programs and diet therapy. Mental health should not be overlooked, with regular screening, and community-based interventions. Infrastructure should support physical activity, and mental health services must become more accessible. Community engagement through support groups and peer networks can foster resilience and social connection. Efforts are needed to promote healthy diets and ensure access to nutritious foods.

RESUMO

Adipose tissue, as an endocrine organ, secretes several adipocyte-derived hormones named 'adipokines' that are implicated in regulating energy haemostasis. Substantial evidence shows that white adipose tissue-derived adipokines mediate the link between obesity-related exogenous factors (like diet and lifestyle) and various biological events (such as pre- and postmenopausal status) that have obesity consequences (cardiometabolic disorders). One of the critical aetiological factors for obesity-related diseases is the dysfunction of adipokine pathways. Acylation-stimulating protein (ASP) is an adipokine that stimulates triglyceride synthesis and storage in adipose tissue by enhancing glucose and fatty acid uptake. ASP acts via its receptor C5L2. The primary objective of this review is to address the existing gap in the literature regarding ASP by investigating its diverse responses and receptor interactions across multiple determinants of obesity. These determinants include diet composition, metabolic disorders, organ involvement, sex and sex hormone levels. Furthermore, this article explores the broader paradigm shift from solely focusing on adipose tissue mass, which contributes to obesity, to considering the broader implications of adipose tissue function. Additionally, we raise a critical question concerning the clinical relevance of the insights gained from this review, both in terms of potential therapeutic interventions targeting ASP and in the context of preventing obesity-related conditions, highlighting the potential of the ASP-C5L2 interaction as a pharmacological target. In conclusion, these findings validate that obesity is a low-grade inflammatory status with multiorgan involvement and sex differences, demonstrating dynamic interactions between immune and metabolic response determinants.

RESUMO

Objectives: This study aims to identify a new barrier to the use of the Mini-Nutrition Assessment Short-Form (MNA-SF), which is a malnutrition assessment tool for the risk assessment of sarcopenia in a nourished population. Methods: The MNA-SF was completed, and individuals with a score of > 11 were considered nourished in this cross-sectional feasibility study of a registry. Sarcopenia was assessed in 766 healthy, nourished adults (33.4% men, 64.9 ± 7.1 years) based on the European Working Group on Sarcopenia in Older People 2 (EWGSOP2). Results: The MNA-SF scores for non-sarcopenia, pre-, confirmed, and severe sarcopenia were 13.59 ± 0.69, 13.73 ± 0.60, 12.64 ± 0.74, and 12.5 ± 0.71, respectively. The higher MNA-SF score association with pre-sarcopenia [odds ratio (OR): 1.41, 95% confidence interval (CI): 1.06-1.86, P = 0.02], confirmed sarcopenia (OR = 0.25, 95% CI: 0.13-0.49, P < 0.001), and severe sarcopenia (OR = 0.20, 95% CI: 0.09-0.46, P < 0.001) was as significant as in the MNA-SF categories. Individuals with a score = 13 (compared with 14), had a higher risk of confirmed sarcopenia (OR = 10.07, 95% CI: 1.92-52.71, P = 006) and severe sarcopenia (OR = 12.09, 95% CI: 1.24-117.50, P = 0.032). Individuals with a score of 12 had a higher risk of confirmed sarcopenia (OR = 30.94, 95% CI: 4.25-103.02, P < 0.001) and severe sarcopenia (OR = 35.90, 95% CI: 4.25-303.07, P = 0.001) compared with subjects with a score of 14. The models also showed that MNA-SF < 13 could predict sarcopenia. Conclusion: There was a significant association between MNA-SF and confirmed and severe sarcopenia in nourished people. Sarcopenia assessment in people with MNA-SF < 13 can be beneficial. Developing a tool to identify the risk of malnutrition and sarcopenia at the same time based on MNA-SF can be considered.

RESUMO

Background: Lifestyle modifications have been recommended as an essential treatment approach for cardiovascular diseases. Recent studies have shown that eating frequency (EF) correlates with hypertension and related risk of organ damage. This study aimed to examine critical clinical implications to evaluate the association of EF with arterial stiffness parameters as an early marker of atherosclerosis manifestations. Methods: A cross-sectional descriptive study was performed on 658 participants of the PERSIAN Organizational Cohort study in Mashhad, aged 30–70 years. Arterial stiffness was assessed by measurement markers of arteriosclerosis, including arterial age, augmentation index (AIx), augmentation pressure (AP), carotid-femoral pulse wave velocity (Cf-PWV), and central blood pressure. Differences in anthropometric indices, blood indices, and arterial stiffness parameters were evaluated across EF groups. Results: Our data demonstrate that EF was positively correlated with total daily energy intake, and favourable profiles of adiposity and blood lipids. Subjects with an increased EF, had significantly lower AIx, AP, Arterial Age and Central blood pressure (P for trend<0.001) as compared to Lowest EF and not significant with PWV (P for trend, 0.19). Arterial stiffness was also significantly lower in those with increased EF compared with subjects with low EF. By Linear regression analysis, after adjustment for Confounding factors, except PWV, EF showed the associations with all of the non-invasive arterial stiffness parameters. Conclusion: Increased EF is associated with a lower wave reflection and blood pressure in the central arteries.(AU)


Introducción: Las modificaciones del estilo de vida se han recomendado como un enfoque de tratamiento esencial para las enfermedades cardiovasculares. Estudios recientes han demostrado que la frecuencia de las comidas (EF) se correlaciona con la hipertensión y el riesgo relacionado de daño orgánico. Este estudio tenía como objetivo examinar las implicaciones clínicas críticas para evaluar la asociación de la EF con los parámetros de rigidez arterial como un marcador temprano de las manifestaciones de la aterosclerosis. Métodos: Se realizó un estudio descriptivo transversal en 658 participantes del estudio de cohorte organizativo PERSIAN en Mashhad, de entre 30 y 70 años de edad. La rigidez arterial se evaluó mediante la medición de marcadores de arteriosclerosis, incluyendo la edad arterial, el índice de aumento (AIx), la presión de aumento (AP), la velocidad de la onda del pulso carótido-femoral (Cf-PWV) y la presión arterial central. Se evaluaron las diferencias en los índices antropométricos, los índices sanguíneos y los parámetros de rigidez arterial en los grupos de EF. Resultados: Nuestros datos demuestran que la EF se correlacionó positivamente con la ingesta energética diaria total, los perfiles favorables de adiposidad y los lípidos sanguíneos. Los sujetos con una EF aumentada, tenían un AIx, una AP, una edad arterial y una presión arterial central significativamente menores (p de tendencia <0,001) en comparación con la EF más baja y no significativa con la PWV (p de tendencia, 0,19). La rigidez arterial también fue significativamente menor en los sujetos con una mayor FE en comparación con los sujetos con una FE baja. Mediante un análisis de regresión lineal, después de ajustar los factores de confusión, excepto la VOP, la frecuencia de las comidas se asoció con todos los parámetros de rigidez arterial no invasivos. Conclusiones: El aumento de la FE se asocia a una menor reflexión de la onda y a una menor presión arterial en las arterias...(AU)

RESUMO

Introduction: Gastric bypass surgery is a gold standard therapy for severe obesity. This study aimed to evaluate anthropometric predictors for short-term excess weight loss (EWL) after Roux-en-Y gastric bypass surgery (RYGB) in a sample of severely obese patients. Materials and Methods: This cohort study was conducted on severely obese candidates for RYGB bariatric surgery in Mashhad, Iran. Indirect calorimetry, anthropometric measurements, and body composition data were collected before, one, and six months after RYGB. Results: Fifty-four participants (43, 79.6% women and 11, 20.4% men) with a mean age of 39.63 ± 9.66 years participated in this study. The mean total weight and BMI loss within six months were 32.89 ± 20.22 kg and 12.37 ± 7.34 kg/m2, respectively. The mean reduction in adipose tissue and fat-free mass was 24.49 kg and 7.46 kg, respectively. The mean resting metabolism rate (RMR) reduction at one and six months after RYGB was 260.49 kcal and 396.07 kcal, respectively. There was a significant difference in mean RMR between the baseline and one and six months after RYGB (p < 0.001). There was no significant gender difference in mean weight and BMI loss percentage at six months post-RYGB (p > 0.05). Baseline skeletal muscle mass (SMM), excess BMI loss (EBMIL) at first month after surgery, and baseline neck circumference (NC) could predict EWL six months after surgery. Conclusion: Reduced RMR shortly after RYGB may be due to FFM reduction. Some anthropometric and their acute changes after RYGB may predict the short-term EWL in RYGB patients.

RESUMO

Introduction: Low serum vitamin D has been shown to be a risk factor for Coronavirus 2019 (COVID-19). The aim of this study was to assess the effects of high dose vitamin D supplementation on hs-CRP, ESR and clinical outcomes, including duration of hospitalization, quality of life and New York Heart Association (NYHA) Functional Classification, in adults with COVID-19. Methods: This double-blind, randomized control trial will be conducted on patients with RT-PCR and/or chest CT scan diagnosis of COVID-19 admitted in Imam Reza Hospital, Mashhad, Iran. Participants will be randomized into control and intervention groups based on randomization sampling. The intervention group will receive soft gel containing 50,000 IU vitamin D on the first day followed by 10,000 IU/day through a supplement drop daily for 29 days. The control group will receive 1000 IU vitamin D daily through supplement drop and a placebo soft gel. All participants will undergo laboratory assessment including inflammatory markers, serum 25)OH)D, complete blood count (CBC), liver and renal profile, lipid profile and erythrocyte sedimentation rate (ESR) at baseline and at day 30. The mortality rate will be recorded in both groups. Results: Data will be presented using descriptive statistics. Comparison of changes in study parameters over the study period will be performed using analysis of covariance adjusting for possible confounders. Conclusions: The findings of this will provide evidence on the effects of high dose vitamin D supplementation on inflammatory markers in hospitalized COVID-19 patients.

RESUMO

The present study aimed to assess the relative validity and reliability of a modified Food and Nutrition Literacy (M-FNLIT) questionnaire in primary school children in the city of Mashhad. The study was conducted in four phases. In the first step, the content and face validity of the questionnaire were evaluated by Delphi consensus as well as interviewing the students. Then, construct validity was examined using Confirmatory Factor Analysis (CFA). The internal consistency and reliability of the questionnaire were also assessed using Cronbach α and Intraclass Correlation Coefficient (ICC), respectively. Finally, a receiver operating characteristic analysis was performed to detect the cut-off scores of the M-FNLIT scale. Findings of two rounds of Delphi showed satisfactory levels of Content Validity Ratio: 0·72 and 0·92, Content Validity Index (CVI): 0·92 and 0·98, respectively. The results of CFA for domains and subscales of the M-FNLIT questionnaire including cognitive domain (understanding food and nutrition information and nutritional health knowledge) and skill domain (functional, food choice, interactive, and critical skills) indicated acceptable fit indices. M-FNLIT subscale-specific Cronbach α values ranged between 0·68 and 0·8 and ICC was 0·95 (95 % CI 0·93, 96). The final questionnaire included forty items (thirty-six Likert-type and four true-false items). FNLIT scores were categorized as low (≤ 58), medium (> 58­< 81), and high (≥ 81). The M-FNLIT questionnaire has a good level of validity and reliability to measure food and nutrition literacy in primary school children. The questionnaire can be applied in the evaluation of nutritional interventions in this age group.

RESUMO

BACKGROUND: Arterial stiffness (AS) indicates the initial stage of cardiovascular disease (CVD), which is associated with modifiable and lifestyle risk factors. We aimed to examine the association of AS with anthropometric indices, lipid profiles and physical activity (PA). METHODS: Six hundred and fifty-eight healthy middle-aged adults were selected and anthropometric indices [body mass index, waist circumferences (WC), waist-to-hip ratio (WHR), waist-to-height ratio (WHtR), neck circumferences, a body shape index (ABSI), body roundness index (BRI), body fat mass (BFM), visceral fat area, fat-free mass (FFM), lipid profiles and PA] were measured. AS is measured by carotid-femoral pulse wave velocity (cf-PWV) and central augmentation index (cAIx). RESULTS: Our results show that cf-PWV was positively associated with TGs (ß = 0.10, P = .01) and anthropometric indices correlated with WC (ß = 0.11, P = .02), WHR (ß = 0.09, P = .03), WHtR (ß = 0.1, P = .02) and BRI (ß = 0.09, P = .04). cAIx was independently positively associated with cholesterol (ß = 0.08, P = .03), WC (ß = 0.1, P = .03), WHR (ß = 0.09, P = .02), ABSI (ß = 0.09, P = .01), BRI (ß = 0.08, P = .05), visceral fat area (ß = 0.09, P = .03) and BFM (ß = 0.08, P = .04) and negatively associated with PA (ß = -0.08, P = .03). CONCLUSIONS: WC, WHR and BRI were associated with both cf-PWV and cAIx. TGs and WHtR were associated with cf-PWV, while cAIx was associated with ABSI, improving these indices may be helpful to prevent CVD.

RESUMO

OBJECTIVE: Many arthritic patients have the belief that dietary habits can worsen or ameliorate their symptoms. Whether diet quality can modify the risk of rheumatoid arthritis (RA) is an issue of continued scientific debate and interest. Therefore, we aimed to examine the association between both overall diet quality and the overall diet inflammatory potential on the risk of RA. DESIGN: Overall diet quality and the overall inflammatory potential of the diet were evaluated with the use of Dietary Inflammatory Index (DII) and the Healthy Eating Index (HEI)-2015, respectively. Both DII and HEI-2015 scores were calculated based on a validated semi-quantitative FFQ. Multivariable-adjusted odds of RA were calculated across tertiles of HEI, and energy-adjusted DII (E-DII) scores using binary logistic regression. SETTING: Mashhad, Iran. PARTICIPANTS: Fifty newly diagnosed RA cases and 100 well-matched healthy people controls. RESULTS: Individuals in the highest tertile of DII scores, indicating the most pro-inflammatory diet, were about three times more likely to have RA than those in the lowest tertile (OR: 2·99; 95 % CI 1·08, 8·24; P-trend: 0·037), whereas individuals in the highest tertile of HEI scores, indicating more top dietary quality, had a significantly lower odds of RA than those in the lowest tertile (OR: 0·33; 95 % CI 0·12, 0·87; P-trend: 0·024). CONCLUSIONS: Our findings show that E-DII and HEI-2015 are positively and negatively associated, respectively, with the odds of RA in a convenience sample of Iranians. These results highlight the importance of overall diet quality in modulating the risk of RA.

RESUMO

BACKGROUND: Evidence suggests that dietary patterns might act as environmental triggers in the development of chronic disorders such as rheumatoid arthritis (RA). However, data regarding the relationship between food patterns and RA are still limited and conflicting. In the current study, the authors aim to evaluate a link between major dietary patterns and RA in new case patients. METHODS: This study was conducted in a case-control manner on 50 patients with newly diagnosed RA and 100 healthy individuals living in Mashhad, Iran. The individuals' dietary intake was assessed using a validated food frequency questionnaire (FFQ). The major dietary patterns were identified using factor analysis based on data from FFQ. Multivariable-adjusted logistic regression models were used to measure the associations between patterns and RA. RESULTS: Three major dietary patterns were identified. High-level adherence to Western pattern had a positive association with RA (multivariable-adjusted OR tertile 3 vs. 1:1.95; 95% CI: 1.09-3.92; p-trend: .046), while the healthy pattern was inversely related to RA (multivariable-adjusted OR tertile 3 vs. 1:0.12; 95% CI: 0.03-0.44; p-trend: .001). No significant association was observed between the traditional pattern and RA. CONCLUSIONS: Our findings revealed that people with dietary behaviors close to the Western dietary pattern are more likely to develop the disease. However, adhering to healthy and well-balanced dietary patterns rich in whole grains, low-fat dairies, white meats, eggs, fruits, vegetables, tea, and vegetable oils was found to be inversely correlated with the risk of RA.
