Navigating sarcopenia in COVID-19 patients and survivors: Understanding the long-term consequences, transitioning from hospital to community with mechanisms and interventions for future preparedness.

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.

The effect of low dietary inflammatory index score formula on inflammatory, metabolic, and clinical outcomes in critically ill traumatic brain injury patients: A single-blind randomized controlled pilot study.

In traumatic brain injury (TBI) patients, a complex cascade of inflammatory responses are frequently observed following trauma. Numerous dietary agents have long been found to have potential in modulating inflammatory responses. This pilot study, designed an enteral formula with low inflammatory properties based on the dietary inflammatory index (DII®) and evaluated its effect on inflammatory and metabolic factors in critically ill TBI patients. This single-blind randomized controlled pilot study was conducted at the Neurosurgical ICU of Shahid Kamyab Hospital (Mashhad, Iran). A total of 20 TBI patients were randomly assigned to receive either low-DII score or standard formula at the intensive care unit (ICU). The primary outcomes of the study included clinical status, inflammatory biomarkers, APACHE II, SAPS II, SOFA, and NUTRIC scores. The trial groups did not differ significantly in baseline values. Following 14 days of intervention, there was a statistically significant decrease in the APACHE II, SAPS II, and NUTRIC scores and a significant increase in the GCS score in the low-DII score formula group compared to the standard formula group. Over 2 weeks, high sensitivity C-reactive protein (hs-CRP) values of -2.73 (95% CI: -3.67, -1.79) mg/dL in the low-DII score formula group versus 0.65 (95% CI: -0.29, 1.58) mg/dL in controls were obtained. Moreover, the length of hospital stay was longer for the standard formula group than for the low-DII score formula group. The low-DII score formula improves inflammatory factors (serum hs-CRP) and metabolic biomarkers (LDL-c and FBS). Furthermore, clinical outcomes, including the length of hospital stay and disease severity, appear to be enhanced.

Dietary inflammatory index and healthy eating index-2015 are associated with rheumatoid arthritis.

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.

Major dietary patterns and food groups in relation to rheumatoid arthritis in newly diagnosed patients.

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.

The effect of pomegranate (Punica granatum) supplementation on metabolic status in patients with type 2 diabetes: A systematic review and meta-analysis.

OBJECTIVE: Several randomized controlled clinical trials (RCTs) have investigated the effect of pomegranate (Punica granatum) supplementation in patients with type 2 diabetes mellitus (T2DM), with conflicting results. Therefore, the present study assessed the effect of pomegranate on metabolic status and oxidative stress in patients with T2DM. METHODS: A comprehensive search was conducted in Pubmed, EMBASE, ISI web of science, Cochrane library and Scopus databases until April 2020, to identify RCTs investigating the effect of pomegranate supplementation on glycemic markers (fasting blood glucose (FBG), homeostasis model assessment-estimated insulin resistance index (HOMA-IR), glycosylated hemoglobin percentage (HbA1c) and insulin levels), anthropometric indices (body mass index (BMI) and body weight (BW)), blood lipids (triglycerides (TG), total cholesterol (TC), high lipoprotein cholesterol (HDL-C) and low lipoprotein cholesterol (LDL-C)), inflammatory markers (high sensitive c-reactive protein (Hs-CRP)) and markers of oxidative stress (total antioxidant capacity (TAC)) in adults with T2DM. Mean difference was pooled using a random-effects model. RESULTS: Seven trials, comprising 350 participants, were included in the present systematic review and meta-analysis. The results of the meta-analysis revealed that pomegranate supplementation did not have any significant effects on metabolic status and oxidative stress biomarkers of subjects with T2DM. There were no evidence of publication bias regarding to selected outcomes. CONCLUSION: There were no significant favorable effects of pomegranate supplementation on metabolic parameters in patients with T2DM. Future well-designed, large scale RCTs, with longer duration are needed in this field.

Dietary Inflammatory Index is associated with Healthy Eating Index, Alternative Healthy Eating Index, and dietary patterns among Iranian adults.

BACKGROUND: Recent investigations have evaluated the effect of the inflammatory potential of diet in several populations by calculating the Dietary Inflammatory Index (DII) score. We aimed to evaluate the association of the DII with the Healthy Eating Index (HEI), the Alternative Healthy Eating Index (AHEI), and dietary pattern (DP) among healthy Iranian adults. METHODS: A cross-sectional study was conducted among 4365 middle-aged adults. Major DPs and DII score were identified using a validated semi-quantitative food frequency questionnaire (FFQ). Poisson regression was used to evaluate the association of DPs, HEI, and AHEI across tertiles of DII. RESULTS: After adjustment for confounding variables, a low HEI (HEI < 55) and AHEI (AHEI < 56.5) were more prevalent among the participants in the highest tertile of DII compared to the first tertile (PR: 1.13, P-value <.05; PR: 1.10, P-value <.05; respectively). Adherence to a balanced healthy dietary pattern was significantly lower in subjects with a diet that was more pro-inflammatory compared to those with anti-inflammatory diet (PR: 0.85, P-value P < .01). No significant association was found between the DII and a western DP. High levels of HDL and hip and waist circumference were observed in the highest tertile of DII, and high levels of dietary intake of protein and fiber, minerals, fasting blood glucose, and monounsaturated fat were reported in the lowest tertile of DII. CONCLUSION: The highest tertile of the DII (a pro-inflammatory diet) was associated with a lower HEI, AHEI, and lower adherence to balanced DP in a representative sample of adults in Iran.

Randomized Controlled Trial of Comparative Hypocaloric vs Full-Energy Enteral Feeding During the First Week of Hospitalization in Neurosurgical Patients at the Intensive Care Unit.

BACKGROUND: Nutrition support plays a pivotal role in improving the clinical outcomes of the patients admitted to the intensive care unit (ICU). However, there are controversies regarding the optimal amount of energy for the reduction of morbidity and mortality in neurosurgical patients at the ICU. METHODS: This randomized clinical trial was conducted on 560 patients who were admitted to trauma, stroke, and neurosurgery ICUs, and 68 patients were enrolled based on the inclusion criteria. In total, data of 58 patients were analyzed. In the full-energy group, enteral feeding started at 75% of their daily energy expenditure and gradually increased to 90%-100%. In the hypocaloric group, enteral feeding started with 30% of the daily energy expenditure and reached 75% within 7 days of the intervention. RESULTS: No significant differences were observed in the baseline characteristics of the patients in the hypocaloric and full-energy groups. The incidence of severe gastrointestinal intolerance was relatively high in the full-energy group (P < .001). Duration of mechanical ventilation and length of hospital stay were lower in the hypocaloric group compared with the full-energy group (P = .014 and P = .046, respectively). However, no significant differences were denoted in the length of ICU admission (P = .163), 28-day mortality (P = .640), and pneumonia (P = .162) between the study groups. CONCLUSIONS: In the neurocritical care unit, hypocaloric enteral feeding was associated with lower gastrointestinal intolerance, as well as reduced duration of ventilator dependence and length of hospital stay.
