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.

Evaluation of the Effects of Atorvastatin and N-Acetyl Cysteine on Platelet Counts in Patients with Primary Immune Thrombocytopenia: An Exploratory Clinical Trial.

Objective: We aimed to evaluate the efficacy of the combination of atorvastatin and N-acetyl cysteine in increasing platelet counts in patients with immune thrombocytopenia who were resistant to steroid therapy or had a relapse after treatment. Material and Methods: The patients included in this study received oral treatment of atorvastatin at a dose of 40 mg daily and N-acetyl cysteine at a dose of 400 mg every 8 h. The desired treatment duration was 12 months, but we included patients who completed at least 1 month of treatment in the analysis. The platelet counts were measured prior to the administration of the study treatment and in the first, third, sixth, and twelfth months of treatment (if available). A p value < 0.05 was considered statistically significant. Results: We included 15 patients who met our inclusion criteria. For the total treatment duration, the global response was 60% (nine patients); eight patients (53.3%) had a complete response and one patient (6.7%) had a partial response. Six patients (40%) were considered as having undergone treatment failure. Of the responder group, five patients maintained a complete response after treatment (55.5%), three patients maintained a partial response (33.3%), and one patient (11.1%) lost their response to the treatment. All of the patients in the responder group had significant increases in their platelet counts after treatment (p < 0.05). Conclusion: This study provides evidence of a possible treatment option for patients with primary immune thrombocytopenia. However, further studies are needed.

Phase angle and overhydration are associated with post-extubating dysphagia in patients with COVID-19 discharged from the ICU.

BACKGROUND: Few studies have evaluated the prevalence of post-extubation dysphagia and associated factors in patients with coronavirus disease 2019 (COVID-19) . Our study assessed the prevalence of post-extubation dysphagia and body composition in patients with COVID-19 discharged from an intensive care unit (ICU). METHODS: A prospective cohort study was performed in post-ICU extubated patients with acute respiratory distress syndrome related to COVID-19 in two referral hospitals. A total of 112 patients were evaluated and included; swallowing assessment and bioelectrical impedance analysis (BIA) were performed after extubation and discharge from the ICU. To identify associations between dysphagia, lower phase angle (PhA) (<4.8°) and hydration (extracellular water/total body water < 0.390) logistic and linear regression analyses were conducted. RESULTS: The incidence of post-extubation dysphagia was 41% (n = 46). From these, 65% (n = 30) had severe swallowing impairment. Overhydration and PhA were significantly different in patients with dysphagia, and segmental hydration in the trunk and legs was higher than in arms. PhA <4.8° (odds ratio [OR], 12.2; 95% CI, 4.3-34.1; P < .05) and overhydration measured by BIA (OR, 9.1; 95% CI, 3.4-24.5; P < .05) were associated with post-extubation dysphagia in multivariate analysis. PhA (<4.8°) was associated with a lower rate of swallowing recovery at hospital discharge (log-rank test = 0.007). CONCLUSIONS: A high incidence of post-extubation dysphagia was found in patients with COVID-19. Low PhA and overhydration were associated with the presence of dysphagia. Lower PhA was an independent factor for swallowing recovery at discharge.

Body composition by bioelectrical impedance, muscle strength, and nutritional risk in oropharyngeal dysphagia patients / Composición corporal mediante impedancia bioeléctrica, fuerza muscular y riesgo nutricional en pacientes con disfagia orofaríngea

INTRODUCTION: oropharyngeal dysphagia (OD) has complications such as malnutrition and dehydration. Body composition is an important factor for nutritional status. OBJECTIVE: to evaluate the presence of cachexia, phase angle, muscle strength, and nutritional risk according to the type of feeding regimen tolerated by patients, determined with the volume-viscosity swallow test (V-VST). METHODS: this cross-sectional study included hospitalized adults of both sexes with a diagnosis of OD established by the Eating Assessment Tool and V-VST. Nutritional risk status was assesed using the Nutritional Risk Screening-2002 tool. Phase angle and cachexia were determined through bioelectrical impedance vector analysis (BIVA), and functional capacity through handgrip strength (HGS) and anthropometric parameters. RESULTS: seventy-nine patients with a median age of 73 years (56-79 yrs) were included; 79.9 % of patients were categorized at nutritional risk. According to the V-VST, 27 (34.2 %) patients tolerated nectar viscosity; 27 (34.2 %) belonged to the spoon-thick and 25 (31.6 %) to the exclusive tube feeding groups. In the exclusive tube feeding group a lower phase angle (3.7° ± 0.9) and lower HGS of 9 kg (5-15) were observed in comparison to the nectar and spoon-thick groups (in both, 4.6° ± 1.1, p = 0.005), which featured 20 kg (16-31) and 19 kg (14-26), respectively (p = 0.03). CONCLUSION: nutritional risk was present in 79.9 % of the study population. BIVA allows to evaluate the integrity of muscle mass and tissue hydration, both related to phase angle. A lower phase angle and HGS were observed in the exclusive tube feeding group. These factors are considered important for prognosis

El riesgo nutricional se evaluó con la herramienta Nutritional Risk Screening-2002. La composición corporal se determinó mediante impedancia eléctrica y la fuerza de prensión por dinamometría, entre otros parámetros antropométricos. RESULTADOS: se incluyeron 79 pacientes con una mediana de edad de 73 años (56-79 años). El 79,9 % de los pacientes presentaban riesgo nutricional. Según el MECV-V, 27 (34,2 %) toleraron la viscosidad néctar y 27 (34,2 %) la viscosidad puré, y 25 (31,6 %) requirieron alimentación exclusiva por sonda. En el grupo de alimentación por sonda se observaron un AF menor (3,7° ± 0,9) y una fuerza de presión más baja de 9 kg (5-15) en comparación con los grupos de néctar y puré (en los dos parámetros: 4,6° ± 1,1, p = 0,005), con 20 kg (16-31) y 19 kg (14-26) (p = 0,03), respectivamente. CONCLUSIÓN: la impedancia eléctrica permite evaluar la integridad y la hidratación de los tejidos, ambas relacionadas con el AF. Se observó que el AF y la fuerza de prensión fueron menores en el grupo con nutrición exclusiva por sonda. Estos factores se consideran importantes para el pronóstico de estos pacientes

Design and implementation of modified-texture diet in older adults with oropharyngeal dysphagia: a randomized controlled trial.

BACKGROUND/OBJECTIVES: Oropharyngeal dysphagia (OD) is a common problem in elderly population that negatively affects the oral intake and body composition resulting in clinical complications as malnutrition and dehydration. The aim of this study was to design, implement, and evaluate the effect of texture-modified foods and thickened drinks diet, with nectar or pudding viscosity and controlled bolus volume in older adults with OD on body composition and oral intake. SUBJECTS/METHODS: Randomized clinical trial, simple blind. Patients ≥ 65 years, admitted at a national institute, who had a confirmed diagnosis of OD were included. A texture-modified foods and thickened drinks diet, with nectar or pudding viscosity and controlled bolus volume, was compared to isocaloric standard treatment for 12 weeks. Body composition was evaluated by bioelectrical impedance, muscular functionality was evaluated by handgrip strength, and daily energy and protein intake by 24-h recall and evaluated by Food Processor Nutrition Analysis® software. RESULTS: Twenty participants were included per group, with mean age 76 years. After 12 weeks, the consumption of energy (29 ± 10 to 40 ± 15 kcal/kg, p = 0.009) and protein (1.3 ± 0.6 to 1.8 ± 0.7 g/kg, p = 0.03), as well as phase angle (4.4 ± 1.8 to 5.5 ± 2.5°, p = 0.05), body weight (56 ± 10 to 60 ± 10 kg, p < 0.001), and handgrip strength (18 ± 11 to 21 ± 13 kg, p = 0.004) increased in the intervention group. In control group there were no changes. CONCLUSIONS: The dietary intervention improved oral intake, weight, handgrip strength, and phase angle, which can prevent or limit the nutritional complications associated with the OD.
