RESUMO

Previous studies have demonstrated that a low skeletal muscle mass (SMM) is an adverse factor for overall survival (OS) in diffuse large B-cell lymphoma (DLBCL). However, its association with the treatment response has not been extensively investigated. This study aimed to determine the association between low skeletal muscle mass (SMM) and treatment response in DLBCL patients. We conducted a retrospective cohort study of 123 patients with DLBCL, in whom SMM was assessed using computed tomography before chemotherapy administration. The demographic characteristics of the patients with low SMM and those with normal SMM were not statistically different. However, there were notable differences in weight and BMI; patients with low SMM had a lower mean weight (59.2 vs 63, p = 0.002) and a higher proportion of patients with normal BMI (61.5% vs. 21.1%, p < 0.001). In addition, patients with low SMM were more likely to receive R-CHOP-like treatment (21.2% vs. 7%, p = 0.022) and experienced more delays in administration (42.9% vs. 33.3%, p = 0.452). Low SMM was not associated with failure to achieve CR (HR 1.9; 95% CI [0.9-4.1] p = 0.84), but it was reported to risk OS in univariate analysis (HR 2.1; 95% CI [1.03-4.2], p = 0.041). An interesting result was the interaction of low SMM with hypertension as a risk factor for not achieving CR (HR 2.7; 95% CI [1.1-6.5] p = 0.034) or OS (HR 7.9; 95% CI [3.4-18.8] p < 0.001). Low SMM was not a risk factor for achieving CR in patients with DLBCL and seemed to play a role in OS.

RESUMO

INTRODUCTION: Aging is accompanied by changes in body composition, such as an increase in fat mass (FM), a decrease in skeletal muscle mass index (SMMI) and muscle strength, combined with a chronic inflammatory process (CI). OBJECTIVE: Determine the relationship between age and excess body fat with markers of chronic inflammation, skeletal muscle mass and strength. METHODS: A cross-sectional alitical study was carried out in a convenience sample of adults 45 to 59 years old (n = 100) and older adults 60 to 74 years old (n = 133). All participants had their body composition measured with an impedance meter. They were subsequently divided into two groups: (i) with excess fat (WEF), (ii) without excess fat (NEF), in order to relate excess fat and age with inflammation, muscle mass and strength. RESULTS: NEF adults and older adults had similar values of SMMI (9.1 ± 1.5 vs. 8.8 ± 1.3, p > 0.05) and strength (28 ± 8 vs. 27 ± 8.6, p > 0.05). Likewise, WEF adults showed significantly lower values than NEF adults in the SMMI (7.9 ± 0.8 vs. 9.1 ± 1.5, p < 0.05) and strength (28 ± 8 vs. 22 ± 5, p < 0.001). Also, WEF older adults presented significantly lower values in the SMMI (15.9 ± 1.8 vs. 22.8 ± 5.1, p < 0.05) and strength (17.9 ± 4.8 vs. 27 ± 8.6, p < 0.001). CONCLUSIONS: Our findings suggest that excess fat mass is a risk factor that has a significantly greater influence than aging per se on the index of skeletal muscle mass and strength.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.
