Inflammatory profile in patients with rheumatoid arthritis and sarcopenia.

INTRODUCTION: Sarcopenia is characterized by the loss of muscle mass and strength associated with aging; however, individuals with chronic diseases are at risk at the early stages. In rheumatoid arthritis (RA), sustained chronic inflammation influences muscle deterioration. It may expedite the development of sarcopenia, which has been linked to physical disability, cardiovascular events, disease activity of RA, and premature death. We aimed to compare the inflammatory profiles of patients with RA with and without sarcopenia. METHODS: This cross-sectional study involved 165 women with RA. Sarcopenia was diagnosed according to criteria established by the European Working Group on Sarcopenia in Older People. To assess the inflammatory profile, concentrations of cytokines such as EGF, IL-17, IL-1α, IL-1ß, IL-6, TNFα, TNFß, and creatine kinase (CK) were measured. RESULTS: The prevalence of sarcopenia was 15.8% (95% CI: 8.9-18.2). The median age of patients with sarcopenia was 59.5 years (49.8-65.3), compared to 50 years (43-59 years) p = 0.001. The disease duration was also longer in patients with sarcopenia, 21 years (15-30), compared to those without sarcopenia, 13 years (7.3-20) p = 0.001. The inflammatory profile differed between patients with and without sarcopenia, revealing that the cytokines IL-1α, IL-6, and TNFß concentrations were significantly higher (p < 0.05) in patients with sarcopenia, adjusted for BMI, age, and disease duration. CONCLUSION: Patients with RA and sarcopenia were older and exhibited longer disease duration and higher levels of inflammatory cytokines compared to those without sarcopenia. These findings suggest potential implications for clinical outcomes. Key Points • The prevalence of sarcopenia in women with rheumatoid arthritis was 15.8% (95% CI, 8.9-18.2). • Levels of IL-1α, IL-6, and TNFß cytokines were significantly higher in women with rheumatoid arthritis and sarcopenia compared with those without sarcopenia, adjusted for BMI, age, and disease duration.

Associated factors to the consumption of non-nutritive sweeteners in the Mexican adult population.

OBJECTIVE: To identify the associated factors to the consumption of non-nutritive sweeteners (NNS) in the Mexican adult population since its consumption has increased exponentially worldwide. MATERIALS AND METHODS: An online survey was applied to 5 038 Mexican adults to evaluate the frequency of NNS consumption and classify the population in tertiles. The sociodemographic, lifestyle and health status characteristics of the participants were compared by gradient of NNS consumption, and a multiple linear regression analysis was performed to determine the associated factors to the NNS consumption. RESULTS: The variables that showed a positive association (p≤0.01) with the consumption of NNS were economic income, BMI, smoking, physical activity, diet quality, the presence of chronic diseases (diabetes, hypertension, or dyslipidemias), and the consumption of fruit. The age and the consumption of confectionery and sugar-sweetened beverages were negatively associated (p<0.01) with the consumption of NNS. CONCLUSION: The results of this study help to characterize the target population that is a consumer of NNS since it is recommended not encourage the preference for sweet taste and to promote a decrease in the consumption of both caloric and NNS, preferring the natural flavor of food.

Effect of a texture-modified and controlled bolus volume diet on all-cause mortality in older persons with oropharyngeal dysphagia: Secondary analysis of a randomized controlled trial.

BACKGROUND: Oropharyngeal dysphagia (OD) is common among older adults. Some studies have evaluated the efficacy of a texture-modified diet on mortality but with short-term follow-up. We aimed to evaluate the effect of a texture-modified diet and controlled bolus volume on all-cause mortality after 12 months in older persons with OD. METHODS: This secondary analysis of a randomized clinical trial included patients aged ≥60 years with a diagnosis of OD. They were concurrently and randomly assigned to receive either a texture-modified food diet and controlled bolus volume (intervention group) or standard treatment (control group) with 12 months of follow-up. Secondary outcomes were oral intake, weight, handgrip strength, phase angle, and aspiration pneumonia. Kaplan-Meier analysis and the Cox proportional hazards model were used for mortality analysis. RESULTS: A total of 127 participants (intervention group: 64 and control group: 63) were recruited, with a mean age of 76 years. The probability of all-cause mortality was significantly lower in the intervention group (n = 8, 12%) than in the control group (n = 18, 29%) (hazard ratio = 0.36 [95% CI = 0.16-0.86]; P = 0.01). There were 5 (7.9%) and 10 (16.1%) aspiration pneumonia events in the intervention and control groups, respectively (not significant) in 12 months of follow-up. Changes were observed in protein consumption (P = 0.01), body weight (P = 0.04), body mass index (P = 0.004), handgrip strength (P = 0.02), and phase angle (P = 0.04) between the treatment groups. CONCLUSION: Compared with the standard treatment, the dietary intervention improved efficacy by limiting nutrition complications, aspiration pneumonia, and all-cause mortality.

Impact of a multicomponent integrated care delivery program on diabetes care goals achievement: a primary care quality improvement initiative.

AIM: To evaluate the impact of multicomponent integrated care (MIC) delivery program in a primary care real-life setting on diabetes care goals. METHODS: Patients with T2D and usual primary care from the public health system in Mexico were invited to participate in a five-month ambulatory MIC quality initiative (DIAbetes Empowerment and Improvement of Care program, DIABEMPIC). RESULTS: 841 patients who finished the program and with complete data were analyzed. The patients had a mean decrease in hemoglobin A1c, systolic and diastolic pressure, and LDL-cholesterol of 2.4%, 9 mmHg, 3 mmHg, and 22.5 mg/dL, respectively (p < 0.001). The achievement of the optimal triple target goal increased from 1.8% to 26.7% (p < 0.001). In the adjusted analysis, the diabetes knowledge and global self-care behavior score post-intervention, as well as the increment of global self-care behavior score were associated with the optimal composite risk factor control achievement. CONCLUSION: The incorporation of diabetes therapeutic education interventions to improve self-care behaviors along with adequate treatment intensification in diabetes care are fundamental to attaining optimal risk factor control and attenuating disease burden.

Evaluation of Changes in Hydration and Body Cell Mass with Bioelectrical Impedance Analysis after Exercise Program for Rheumatoid Arthritis Patients.

Rheumatoid arthritis (RA) is a debilitating disease that can result in complications such as rheumatoid cachexia. While physical exercise has shown benefits for RA patients, its impact on hydration and body cell mass remains uncertain. The presence of pain, inflammation, and joint changes often restrict activity and make traditional body composition assessments unreliable due to altered hydration levels. Bioelectrical impedance is a commonly used method for estimating body composition, but it has limitations since it was primarily developed for the general population and does not consider changes in body composition. On the other hand, bioelectrical impedance vectorial analysis (BIVA) offers a more comprehensive approach. BIVA involves graphically interpreting resistance (R) and reactance (Xc), adjusted for height, to provide valuable information about hydration status and the integrity of the cell mass. Twelve women with RA were included in this study. At the beginning of the study, hydration and body cell mass measurements were obtained using the BIVA method. Subsequently, the patients participated in a six-month dynamic exercise program encompassing cardiovascular capacity, strength, and coordination training. To evaluate changes in hydration and body cell mass, the differences in the R and Xc parameters, adjusted for height, were compared using BIVA confidence software. The results showed notable changes: resistance decreased after the exercise program, while reactance increased. BIVA, as a classification method, can effectively categorize patients into dehydration, overhydration, normal, athlete, thin, cachectic, and obese categories. This makes it a valuable tool for assessing RA patients, as it provides information independent of body weight or prediction equations. Overall, the implementation of BIVA in this study shed light on the effects of the exercise program on hydration and body cell mass in RA patients. Its advantages lie in its ability to provide comprehensive information and overcome the limitations of traditional body composition assessment methods.

Clinical Application of Phase Angle and BIVA Z-Score Analyses in Patients Admitted to an Emergency Department with Acute Heart Failure.

Acute heart failure is characterized by neurohormonal activation, which leads to sodium and water retention and causes alterations in body composition, such as increased body fluid congestion or systemic congestion. This condition is one of the most common reasons for hospital admission and has been associated with poor outcomes. The phase angle indirectly measures intracellular status, cellular integrity, vitality, and the distribution of spaces between intracellular and extracellular body water. This parameter has been found to be a predictor of health status and an indicator of survival and other clinical outcomes. In addition, phase angle values of <4.8° upon admission were associated with higher mortality in patients with acute heart failure. However, low phase angle values may be due to alterations-such as the shifting of fluids from an intracellular body water (ICW) compartment to an ECW (extracellular body water) compartment and a concurrent decrease in body-cell mass (which can reflect malnutrition)-that are present in heart failure. Thus, a low phase angle may be due to overhydration and/or malnutrition. BIVA provides additional information about the body-cell mass and congestion status with a graphical vector (R-Xc graph). In addition, a BIVA Z-score analysis (the number of standard deviations from the mean value of the reference group) that has the same pattern as that of the ellipses for the percentiles on the original R-Xc graph can be used to detect changes in soft-tissue mass or tissue hydration and can help researchers compare changes in different study populations. This protocol explains how to obtain and interpret phase angle values and BIVA Z-score analyses, their clinical applicability, and their usefulness as a predictive marker for the prognosis of a 90-day event in patients admitted to an emergency department with acute heart failure.

Cachexia measured by bioelectrical impedance vector analysis and risk of infection in women with rheumatoid arthritis.

Rheumatoid arthritis (RA) patients have a higher frequency of infections than the healthy population. The reason has yet to be explained but involves several factors, of which body composition and rheumatoid cachexia are often overlooked. This study aimed to evaluate whether patients with cachexia, measured by bioelectrical impedance vector analysis, are at an increased risk of developing infections compared with patients without cachexia. A secondary analysis of 186 women with RA enrolled in a randomized trial (ClinicalTrials.gov ID: NCT02900898, September 14, 2016) was completed. Medical records and phone calls were used to record infectious events diagnosed and treated during follow-up. Hazard ratios were calculated using Cox proportional hazard regression analysis, and a predictive model of infection was created. After 36 months of follow-up, 62 patients (26.7% non-cachectic and 44.3% cachectic, p < 0.01) developed at least one infectious event. The most common site of was the urinary tract, followed by the lungs and respiratory tract. The presence of cachexia (HR 1.90, 95% CI 1.15-3.13) and the use of glucocorticoids (HR 1.77, 95% CI 1.01-3.09) were associated with infection in univariate and multivariate models. Body mass index (BMI), smoking, and methotrexate use were not associated with a higher frequency of infections. The presence of cachexia and the use of glucocorticoids were identified as predictors of infections in a cohort of female RA patients. More extensive measurements of body composition should be performed beyond BMI in RA patients to better understand its impact and to prevent additional comorbidities and complications. Key Points • The presence of cachexia measured by bioelectrical impedance vector analysis was associated with infectious events in women with rheumatoid arthritis, whereas body mass index did not show an association. • Glucocorticoids were the only drug associated with a higher frequency of infection. None of the disease-modifying antirheumatic drugs, including methotrexate, showed an association.

Evaluation of Fluid Overload by Bioelectrical Impedance Vectorial Analysis.

Early detection and management of fluid overload are critically important in acute illness, as the impact of therapeutic intervention can result in decreased or increased mortality rates. Accurate fluid status assessment entails appropriate therapy. Unfortunately, as the gold standard method of radioisotopic fluid measurement is costly, time-consuming, and lacks sensitivity in the acute care clinical setting, other less-accurate methods are typically used, such as clinical examination or 24 h output. Bioelectrical impedance vectorial analysis (BIVA) is an alternative impedance-based approach, where the raw parameter resistance and reactance of a subject are plotted to produce a vector, the position of which can be evaluated relative to tolerance intervals in an R-Xc graph. The fluid status is then interpreted as normal or abnormal, based on the distance from the mean vector derived from a healthy reference population. The objective of the present study is to demonstrate how to evaluate the presence of fluid overload through bioelectrical impedance vectorial analysis and the impedance ratio measured with tetrapolar multi-frequency equipment in patients admitted to the emergency department.

Adherence to antidiabetic treatment in primary health care in individuals with type 2 diabetes. A survey including socio-demographic, patient related and clinical factors.

BACKGROUND: Adherence to medications is a critical element in diabetes management. OBJECTIVE: To investigate patient-related factors associated with adherence to antidiabetic treatment in patients with type 2 diabetes in primary health-care units. METHODS: A cross-sectional study among patients receiving diabetes care in 18 primary care units in Mexico City was conducted. Data were collected from medical records and medical interviews. Adherence to antidiabetic therapy and patient-related factors associated with adherence were evaluated through a self-administered questionnaire. Socio-demographic, clinical, behavioral (self-care activities including a healthy diet, exercise or physical activity, self-monitoring of blood glucose testing, and foot care), and patients-adherence-related factors (health-care provider-patient communication; daily and social activities, and support network; alternative treatment beliefs; comorbidity, diabetes symptoms, and treatment; side effects and treatment access) were compared between the adherent and non-adherent group. RESULTS: Of 319 outpatients, 48.3% were adherent to their antidiabetic therapy. In the adjusted analysis, patient-related factors associated to adherence were exercise and physical activity self-care behavior (OR=1.26; 95%CI 1.09-1.46), treatment interference with daily activities (OR=0.27; 95%CI 0.14-0.52), not satisfied with resolution of questions by the physician (OR=0.42; 95%CI 0.19-0.94), independently to increased cardiovascular risk and insulin treatment. CONCLUSION: A low proportion of outpatients with T2D with regular primary care were adherent to diabetes treatment and this was associated with patient-related factors like answering patients' treatment-related questions by the physician. This information may be useful to identify patients at risk for low adherence, and to guide the design of quality-of-care strategies, like diabetes education programs to address suboptimal adherence in patients, and health-care professional communication skills training, particularly in primary care health systems.

Characteristics of patients receiving nutrition care and its associations with prognosis in a tertiary hospital.

OBJECTIVE: The aim of this study was to describe the medical nutritional therapy (MNT) of adult non-critically ill hospitalization patients. METHODS: In a retrospective study, adults hospitalized for more than 48 h in non-intensive care unit medical and surgical areas that were classified as being at nutritional risk were included. Malnutrition was defined according to Global Leadership Initiative on Malnutrition (GLIM) criteria. RESULTS: A total of 255 patients, aged 54.13±18.4 years, who were at risk of malnutrition were included in this study. Of these, 50% were males. Notably, 52.5% received oral nutrition supplementation (ONS), 23.5% enteral nutrition (EN), 15% parenteral nutrition (PN), and 9% received enteral and parenteral nutrition (EPN). Patients with EPN presented the highest frequency of malnutrition (52%), and therefore they received more than 100% of energy and protein requirements. The median length of stay was 25 days. Among patients with nutritional risk receiving EPN, no deaths occurred. Patients, identified at nutritional risk, but without malnutrition according to GLIM, and receiving ONS had significantly lower mortality than patients receiving other MNT. CONCLUSIONS: Oral nutrition supplementation was the more frequent MNT prescribed. The frequency of malnutrition and percentage of prescribed energy and protein were higher in patients receiving PN and EPN compared with those receiving ONS.

Comparison of the Impacts of a Dynamic Exercise Program vs. a Mediterranean Diet on Serum Cytokine Concentrations in Women With Rheumatoid Arthritis. A Secondary Analysis of a Randomized Clinical Trial.

Background: Rheumatoid arthritis (RA) is a disease characterized by a chronic inflammatory state. High pro-inflammatory cytokine levels are associated with disease activity. Exercise and the Mediterranean diet (MD) exert anti-inflammatory effects; however, their impacts on inflammation in RA patients remains unknown. This study aimed to compare the effects of six-months of dynamic exercise program (DEP) vs. MD on pro- and anti-inflammatory cytokine serum concentrations. Methods: Secondary analysis of a randomized clinical trial in which 90 women with RA were randomly assigned to the DEP (n = 30), MD (n = 30), or control group (n = 30). All patients received pharmacological treatment. Serum concentrations of pro-inflammatory (TNF-α, TNF-ß, IL-1ß, IL-6 pg/mL) and anti-inflammatory (IL-10, IL-Ra pg/mL) cytokines were measured at baseline and after 6 months using the Luminex technique. Results: After 6 months of follow-up, we found an improvement of the median percentages changes concentrations of TNF-α (DEP, -12.3; MD, -13.3; control, 73.2; p = 0.01), TNF-ß (DEP, -67.4; MD, -54.9; control, 0; p = 0.04), and IL-6 (DEP, -19.9; MD, -37.7; control, 45.5; p = 0.04) in the DEP and MED groups in comparison with control group. IL-1Ra concentrations increased only in the MD group (13.8) compared to levels in the control group (-31.7), p = 0.04. There were no statistically significant differences between DEP and MD groups. Only n = 27 participants in the DEP group, n = 26 in the MD group, and n = 21 in the control group completed the follow-up. Conclusion: The DEP and the MD have potential effects in the concentrations of pro-inflammatory cytokines compared with those in a control group. Only the MD elevated the concentration of IL-Ra. Clinical Trial Registration: [ClinicalTrials.gov], identifier [NCT02900898].

SOFA Score Plus Impedance Ratio Predicts Mortality in Critically Ill Patients Admitted to the Emergency Department: Retrospective Observational Study.

BACKGROUND: The Sequential Organ Failure Assessment (SOFA) is a scoring system used for the evaluation of disease severity and prognosis of critically ill patients. The impedance ratio (Imp-R) is a novel mortality predictor. AIMS: This study aimed to evaluate the combination of the SOFA + Imp-R in the prediction of mortality in critically ill patients admitted to the Emergency Department (ED). METHODS: A retrospective cohort study was performed in adult patients with acute illness admitted to the ED of a tertiary-care referral center. Baseline SOFA score and bioelectrical impedance analysis to obtain the Imp-R were performed within the first 24 h after admission to the ED. A Cox regression analysis was performed to evaluate the mortality risk of the initial SOFA score plus the Imp-R. Harrell's C-statistic and decision curve analyses (DCA) were performed. RESULTS: Out of 325 patients, 240 were included for analysis. Overall mortality was 31.3%. Only 21.3% of non-surviving patients died after hospital discharge, and 78.4% died during their hospital stay. Of the latter, 40.6% died in the ED. The SOFA and Imp-R values were higher in non-survivors and were significantly associated with mortality in all models. The combination of the SOFA + Imp-R significantly predicted 30-day mortality, in-hospital mortality, and ED mortality with an area under the curve (AUC) of 0.80 (95% CI: 74-0.86), 0.79 (95% CI: 0.74-0.86) and 0.75 (95% CI: 0.66-0.84), respectively. The DCA showed that combining the SOFA + Imp-R improved the prediction of mortality through the lower risk thresholds. CONCLUSIONS: The addition of the Imp-R to the baseline SOFA score on admission to the ED improves mortality prediction in severely acutely ill patients admitted to the ED.

Nutritional Status of Patients with Chronic Myeloid Leukemia Treated with Imatinib Mesylate.

Background: Imatinib mesylate (IM) is the treatment of choice in patients with chronic myeloid leukemia (CML). Among its nonhematological adverse events, water retention is the most common, together with weight gain. However, no thorough description of the body composition in these patients has been informed. Therefore, our purpose was to evaluate the nutritional status, body composition and handgrip-strength in patients with CML treated with IM. Methods: We conducted a cross-sectional study in 78 patients (n = 48 men, 30 women) with chronic myeloid leukemia in the chronic (82%) or accelerated (18%) phases. We assessed body mass index (BMI), body composition by bioelectrical impedance, performed vector analysis through Bioelectrical Impedance Vector Analysis, and handgrip-strength measurement in patients with at least 3 months of IM treatment. Hematocrit and hemoglobin values were collected from the medical charts. Results: BMI was within the normal range in 28.2%, indicated overweight in 39.7% and obesity in 30.8%. According to BIVA, 25.6% of the patients were muscle-depleted and were older (p = 0.006) and received lower doses of IM (p < 0.001). Conclusions: In patients with CML with ≥3 months of IM treatment muscular depletion is frequent and is related to lower doses of IM.

Effects on cardiometabolic risk factors after reduction of artificially sweetened beverage consumption in overweight subjects. A randomised controlled trial.

BACKGROUND: The consumption of artificially sweetened beverages (ASBs) has been linked to metabolic alterations. The effect of reducing the regular consumption of these beverages on the metabolism is currently unknown. OBJECTIVE: To evaluate the effect of reducing consumption of ASBs on the metabolism in overweight young adults. DESIGN: A randomised, single-blind, controlled, 12-week, clinical trial was performed in overweight young adults who regularly consume ASBs. The 45 subjects who participated in the study were randomly divided into two groups: (1) control group (n=21) and (2) intervention group (no intake of ASBs, n=24). Body weight and composition, fasting plasma concentrations of glucose, triglycerides, insulin, cholesterol, low-density lipoproteins and high-density lipoproteins were measured at the beginning and end of the study. and the HOMA-IR was calculated. RESULTS: At the end of 12 weeks, the intervention group showed a significant decrease (as opposed to an increase in the control group) in the percentage of change in body weight (-1.22% vs 1.31%, p<0.004), body fat (-6.28% vs 6.15%, p<0.001) and insulin resistance index (-12.06 vs 38.21%, p<0.00002), as well as in levels of glucose (-4.26% vs 0.51%, p<0.05), triglycerides (-14.74% vs 19.90%, p<0.006), insulin (-8.02% vs 39.23%, p<0.00005), cholesterol (-8.71% vs 0.77%, p<0.01) and LDL (-9.46% vs 9.92%, p<0.004). CONCLUSION: A reduction in habitual consumption of ASBs in overweight young adults decreases biochemical measurements, body weight and composition, suggesting a participation in the metabolic processes.

Changes in hand grip strength and body weight after a dynamic exercise program and Mediterranean diet in women with rheumatoid arthritis: a randomized clinical trial.

BACKGROUND: In patients with rheumatoid arthritis (RA) exercise improves muscle strength and decreases fat mass, whereas the consumption of a Mediterranean diet (MD) also has been associated with higher grip strength. Therefore, it is important to explore the combined effects of these interventions on hand grip strength and weight in RA. OBJECTIVE: To determine the combined effect of an MD and a dynamic exercise program (DEP) on hand grip strength in women with RA. METHOD: In a randomized clinical trial, 106 women with RA were included and assigned to the DEP-MD, DEP and MD groups. Weight, body circumferences, Disease Activity Score-28, Health Assessment Questionnaire Disability Index [HAQ-DI], and hand grip strength were measured at baseline and 24 weeks after the interventions. RESULTS: After 24 weeks, hand grip strength showed a significant increase in the DEP group (median 2 kg) compared with DEP-MD (median 0.5 kg) and MD (median -0.5 kg) groups (p = 0.03). In the MD group weight and waist circumference showed a significant decrease (-2.2 kg and -4.3 cm) compared with DEP-MD (0.85 kg and 1.9 cm) and DEP (0.35 kg and 0.5 cm) groups (p < 0.01). Finally, a significant decrease was observed in the HAQ-DI after treatment in the DEP-MD group of -0.5 and the DEP group of -0.25 compared with the MD group with no change (p = 0.03). CONCLUSION: In women with RA, in addition to pharmacological treatment, DEP increases hand grip strength and an MD decreases weight and waist circumferences, while the combination of DEP and MD improves disability.

A low phase angle determined by bioelectrical impedance analysis is associated with oropharyngeal dysphagia among institutionalized older adults.

OBJECTIVE: The aim was to evaluate the prevalence of oropharyngeal dysphagia (OD) and its association with body composition by bioelectrical impedance analysis (BIA) and functionality among institutionalized older adults. METHODS: A cross-sectional study was conducted. The swallowing function and diagnosis of OD were evaluated with a volume-viscosity swallow test. Activities of daily living were evaluated by the Barthel Index. Body composition was evaluated by BIA, and phase angle (PhA) was determined. RESULTS: Eighty institutionalized older adults were evaluated. The mean age of the study population was 82±9.5 years, and 65% were females. The OD prevalence was 30%, dependence was 30%, and sarcopenia was 16%. In the multivariate analysis, a low PhA (<3.5°) was independently associated with the presence of OD adjusted by sex and age (OR: 2.60, 95%CI 2.41-2.90, p=0.01). CONCLUSIONS: A higher prevalence of OD was found. Significant and independent associations were found between low PhA, dependence, and sarcopenia with the presence of OD among institutionalized older persons.
