Adherence to commercial food thickener in patients with oropharyngeal dysphagia.

BACKGROUND: Oropharyngeal dysphagia (OD), a common symptom in the elderly, uses commercial thickener (CT) as part of its treatment. This is often accompanied of dislike and poor compliance. AIM: Describe adherence to CT and possible differences according to dwelling location in an area of influence of approximately 400.0000 inhabitants. METHODS: Cohort prospective observational study. Randomized patients from Nutrition and Dietetic (NDU)-database (4 calls-interviews/year). VARIABLES: Age, diagnostic, gender, dwelling/location: Home (H) / Nursing Home (NH), viscosity (nectar, honey, pudding), days with CT. Adherence measured with a questionnaire, considering implementation of treatment by combining CT use and consumption data, categorised in three groups good, moderate and poor. Change in patterns (improvement, maintenance, worsening) and non-adherence reasons. RESULTS: One hundred sixty-eight patients recruited with indicated viscosity: Nectar 39.7%, honey 29.3% and pudding 30.8%. Average age of 82.6 ± 11.1 years; 57.8% women (46.4% at H vs. 67% at NH, p < 0.01). Dwelling/location: 80 (47.6%) live at H and 88 (52.4%) at NH. Days with CT prior study were 509 ± 475.28. Implementation found in first call: good in 50%, moderate in 20.2% and poor in 29.8%. At first call, adherence parameters were more favourable in NH compared to H. However these parameters were reversed during the study period as there was an improvement at H vs. NH. Also in terms of change in patterns a significant improvement of implementation was found in patients living at H, 31.1% vs. those living at NH, 15.7%, p < 0.05. CT persistence throughout study was 89.7%. CONCLUSIONS: Low adherence to CT found in our community. Telephone follow-up resulted in improved adherence, especially in the H population. Our data provides valuable insights into the variability and changes in CT adherence among patients with OD. Adherence is complex and subject to many factors and dwelling/location is one of them. This study reveals the need to approach CT treatment for OD differently in NH.

Validation of the Spanish version of DYsphagia in MUltiple Sclerosis questionnaire (DYMUS).

BACKGROUND: Dysphagia is a common symptom in multiple sclerosis that can occur even early in the disease course and can lead to serious complications. Early recognition and treatment can promote comfort, safety and optimal nutritional status. Few dysphagia rating scales are available in Spanish. The aim of this study was to translate the Dysphagia in Multiple Sclerosis Questionnaire (DYMUS) into Spanish and to validate it. METHODS: Forward and backward translation method was used to translate the original English version of DYMUS into Spanish. A pilot-study with 10 PwMS was carried on in order to improve the intelligibility of the instrument, comprehensibility and content validity of the questionnaire. The questionnaire was filled out by 100 PwMS who were asked a dichotomous question on their swallowing ("Do you have swallowing troubles?"). Descriptive data are presented as median and quartiles for continuous variables and frequency and percentage for categorical ones. Internal consistency reliability was estimated by Cronbach's alfa. Test-retest reliability was estimated by intraclass correlation coefficient. Concurrent validity with a speech and language therapy assessment (SLT-A) was measured with the weighted kappa statistic for the concordance for both dysphagia type and degree categories. Confirmatory factor analysis by means of structural equation models was used to verify the two-factor (solids and liquids) structure of the DYMUS questionnaire. As the goodness of fit evaluation was poor, an additional exploratory factor analysis was carried out. RESULTS: Internal consistency was high. The globus sensation question and the weight loss questions (item 3 and 10) are the least specific with dysphagia symptomatology so they are worst correlated with the sum of the others (item-rest correlation, 0.243 and 0.248, respectively). The test-retest reliability of the DYMUS among 40 patients using ICC was 0.75 (95% CI 0.57 - 0.86). Concurrent validity with SLT-A was poor (weighted kappa 0.37 for dysphagia type and 0.38 for dysphagia degree). The DYMUS questionnaire detected three times more dysphagia (53% versus 17%) than the dichotomous question. Confirmatory factors analysis failed to confirm the bidimensional structure (solid and liquid items) often reported in other validation studies. The subsequent exploratory factor analysis also identified two factors, but with poor interpretability. CONCLUSION: DYMUS-SP scale is not a sufficiently useful scale to detect dysphagia in PwMS due to the poor concurrent validity and the probable overdiagnosis of the condition; however, it can be helpful as a screening tool when combined with other measures.

Comparison of post-COVID symptoms in patients with different severity profiles of the acute disease visited at a rehabilitation unit.

BACKGROUND AND AIM: Studies in the literature suggest the severity of COVID-19 may impact on post-COVID sequelae. We retrospectively compared the different patterns of symptoms in relation to the severity of acute COVID-19 in patients visited at our post-COVID rehabilitation unit. METHODS: We compared respiratory, muscular, cognitive, emotional, and health-related-quality-of-life (HRQoL) measures in three groups of post-COVID patients: those who had not required hospitalization for the acute disease, those who had been admitted to a general hospital ward, and those who had been admitted to the ICU. The main inclusion criteria were persistent dyspnoea (mMRC ≥2) and/or clinical frailty (scale value ≥3). RESULTS: We analyzed data from 178 post-COVID patients (91 admitted to the ICU, 60 to the ward, and 27 who had not required admission) at first visit to our post-COVID rehabilitation unit. Most patients (85.4%) had at least one comorbidity. There were more males in all groups (58.1%). ICU patients were older (p<0.001). The most frequent symptoms in all groups were fatigue (78.2%) and dyspnea (75.4%). Muscle strength and effort capacity were lower in the ICU group (p<0.001). The SF36 mental component and level of anxiety were worse in patients not admitted to the ICU (p<0.001). No differences were found between groups regarding respiratory pressure but 30 of 57 patients with a decrease in maximum inspiratory pressure had not required mechanical ventilation. CONCLUSION: Clinical profiles of post-COVID syndrome differed between groups. Muscle parameters were lower in the ICU group but patients who had not needed ICU admission had worse anxiety and HRQoL scores. Many patients who had not required mechanical ventilation had respiratory muscle weakness. TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT04852718.

Differences in the use of food textures in oropharyngeal dysphagia according to the place of living.

BACKGROUND&AIMS: Modifying solid/liquid foods is the main treatment in oropharyngeal dysphagia (OD). Commercial Thickener (CT) for treatment is subsidized by health system and is delivered to patient's place of living, once is managed by our hospital Nutrition-Dietetics Unit (NDU). AIM: To describe the patterns of texture for foods/liquids follow in patients with OD who are treated with CT. METHODS: Cohort prospective study. Randomized patients from NDU-database followed throughout 2018 (4 calls-interviews/year). Variables; age, diagnostic, gender, residence type: Home(H)/Nursing Home(NH), thickener manager (patient, family member or caregiver), education, days with commercial thickener (CT), thickener regimen established by Volume/Viscosity test: nectar (N), honey (HY), pudding (P), type of diets; measured by FOIS scale and texture; pureed (PD); soft (SD); mixed (P&S/D); regular (RD), risk foods consumption (RFC), complete diet intake (CI), changes in; diets, intake and RFC. RESULTS: Analysed 204 patients, aged 85 years; (IQR: 78-90), from which 57.8% were women. Residence: 43.6% H/56.4% NH. Days with CT median 380 days (IQR: 153-682). A proper viscosity guideline was indicated in 168 patients: N 37.3%, HY 20.6% and P 24.5%. In 36 patients (17.5%) there were no indications, 75% of them coming from primary care. Despite this, 184 patients (90%) referred a concrete indication; N 35.8%, HY 26% and P 28.4%. The concordance between indicated and referred viscosity was significantly higher at H (Kappa 0.798) compared to NH (Kappa 0.428), p < 0.0001. FOIS: 65.7% followed the total oral diet of a single consistency. Diet textures: PD 66.7%, SD 2.9%, P&S/D 21.1%, RD 9.3%. Difference in PD given in NH 86.1% vs H 41.6%, p < 0.001. Under N viscosity different diet distributions, PD 28.6%H vs 71% NH, p < 0.05. CI in 66.7% with no difference among NH/H. RFC similar but higher consumption of jellies at NH, p < 0.001. CONCLUSIONS: According to this study the place of living determines a better approach to OD treatment. Viscosity and diet texture are more restricted in NH with worse compliance of indicated regimens. Increasing variety in diets and reassessment of OD treatment is desirable.

Prevalence of sarcopenia after remission of hypercortisolism and its impact on HRQoL.

BACKGROUND: Cushing's syndrome (CS) is associated with skeletal muscle structural and functional impairment which may persist long-term despite surgical removal of the source of cortisol excess. Prevalence of sarcopenia and its impact on Health-Related-Quality of Life (HRQoL) in 'cured' CS is not known. There is a need to identify easy biomarkers to help the clinicians recognise patients at elevated risk of suffering sustained muscle function. PATIENTS AND METHODS: We studied 36 women with CS in remission, and 36 controls matched for age, body mass index, menopausal status, and level of physical activity. We analysed the skeletal muscle mass using dual-energy X-ray absorptiometry, muscle fat fraction using two-point Dixon magnetic resonance imaging and muscle performance and strength using the following tests: hand grip strength, gait speed, timed up and go and 30-s chair stand. We assessed HRQoL with the following questionnaires: SarQoL, CushingQoL, SF-36. We calculated the sarcopenia index (SI; serum creatinine/serum cystatin C × 100). RESULTS: Prevalence of sarcopenia, according to the European Working Group on Sarcopenia in Older People (EWGSOP), was greater in CS as compared with controls (19% vs. 3%; p < .05). Patients with sarcopenia had a lower SarQoL score than those without sarcopenia (61 ± 17 vs. 75 ± 14; p < .05), and scored worse on the items pain, easy bruising and worries on physical appearance (p < .05 for all comparisons) of the CushingQoL questionnaire. Patients with sarcopenia had poorer physical functioning on SF-36 than those without sarcopenia (60 ± 23 vs. 85 ± 15; p < .01). SI was lower in patients with sarcopenia than those without (71 ± 3 vs. 77 ± 2; p = .032), and was associated with intramuscular fatty infiltration, worse performance on the 30-s chair stand test, slower gait speed, and worse muscle weakness-related HRQoL, as measured using the SarQoL questionnaire (p < .05). The optimised cut-off value for the SI ratio to diagnose sarcopenia was 72, which yielded a sensitivity of 73% and a specificity of 90%. CONCLUSIONS: Sarcopenia is common in patients with CS in long-term remission, and associated with impaired quality of life. The SI is a potential biomarker allowing clinicians to identify patients at high risk of muscle dysfunction.

Intramuscular fatty infiltration and physical function in controlled acromegaly.

INTRODUCTION: Patients with acromegaly show musculoskeletal symptoms which may persist despite disease control. Increased i.m. fat fraction is a known cause of muscle dysfunction in several disorders. OBJECTIVE: To assess the degree of fat fraction in thigh muscles of controlled acromegaly patients and its relationship with muscle dysfunction. METHODS: In a cross-sectional study, we included 36 patients with controlled acromegaly and 36 matched controls. We assessed the percentage of fat fraction in each thigh muscle, using MRI 2-point Dixon sequence, and muscle performance and strength using the gait speed, timed up and go, 30-s chair stand, and hand grip strength tests. We evaluated joint symptoms using the Western Ontario McMaster Universities Osteoarthritis Index (WOMAC). RESULTS: Intramuscular fat fraction was greater in patients than controls (P < 0.05 for muscle compartments, rectus femoris (RF), vastus intermedius (VI), adductor magnus (AM) and semimembranosus). Patients had slower gait speed and poorer performance on the 30-s chair stand and timed up and go tests than controls (P < 0.05). The greater fat fraction in the combined anterior-posterior compartment and in each muscle was associated with worse performance on timed up and go (P < 0.05). The fat fraction in the anterior-posterior compartment predicted performance on timed up and go after adjusting for muscle area, IGF-I and WOMAC functional and pain scores (ß = 0.737 P < 0.001). CONCLUSIONS: Patients with controlled acromegaly have greater thigh i.m. fatty infiltration, which is associated with muscle dysfunction. Futures studies are needed to elucidate the mechanisms underlying this relationship.

Thigh Muscle Fat Infiltration Is Associated With Impaired Physical Performance Despite Remission in Cushing's Syndrome.

CONTEXT: Muscle weakness is common in patients with Cushing's syndrome (CS) and may persist after the resolution of hypercortisolism. Intramuscular fatty infiltration has been associated with the deterioration of muscle performance in several conditions. OBJECTIVES: To quantify the degree of fatty infiltration in the thigh muscles of "cured" CS patients and evaluate the relationship between intramuscular fatty infiltration and physical performance. DESIGN: This was a cross-sectional study. SETTING: Tertiary referral center. PATIENTS: Thirty-six women with CS in remission, and 36 controls matched for age, BMI, menopausal status, and level of physical activity. MAIN OUTCOME MEASURES: We analyzed the percentage fat fraction (FF) of the thigh muscles in the anterior, posterior, and combined anterior and posterior compartments using MRI and 2-point Dixon sequence. We assessed muscle function and strength using the following tests: gait speed (GS), timed up and go (TUG), 30-second chair stand, and hand grip strength. RESULTS: Fat fraction in all the compartments analyzed was increased in patients as compared with controls. The performance on TUG, 30-second chair stand, and GS was more impaired in CS patients versus controls. In patients, greater FF was negatively associated with performance on functional tests. Fat fraction in the combined anterior and posterior compartments predicted performance on TUG (ß 0.626, P < 0.000) and GS (ß -0.461, P = 0.007), after adjusting for age, BMI, menopausal status, and muscle mass. CONCLUSIONS: Thigh muscle fatty infiltration is increased in "cured" CS patients and is associated with poorer muscle performance. Future studies are needed to establish therapeutic strategies to improve muscle weakness in these patients.

Content validity of the Comprehensive ICF Core Set for multiple sclerosis from the perspective of speech and language therapists.

BACKGROUND: The Comprehensive International Classification of Functioning, Disability and Health (ICF) Core Set for Multiple Sclerosis (MS) is a comprehensive framework to structure the information obtained in multidisciplinary clinical settings according to the biopsychosocial perspective of the International Classification of Functioning, Disability and Health (ICF) and to guide the treatment and rehabilitation process accordingly. It is now undergoing validation from the user perspective for which it has been developed in the first place. AIMS: To validate the content of the Comprehensive ICF Core Set for MS from the perspective of speech and language therapists (SLTs) involved in the treatment of persons with MS (PwMS). METHODS & PROCEDURES: Within a three-round e-mail-based Delphi Study 34 SLTs were asked about PwMS' problems, resources and aspects of the environment treated by SLTs. Responses were linked to ICF categories. Identified ICF categories were compared with those included in the Comprehensive ICF Core Set for MS to examine its content validity. OUTCOMES & RESULTS: Thirty-four SLTs named 524 problems and resources, as well as aspects of environment. Statements were linked to 129 ICF categories (60 Body-functions categories, two Body-structures categories, 42 Activities-&-participation categories, and 25 Environmental-factors categories). SLTs confirmed 46 categories in the Comprehensive ICF Core Set. Twenty-one ICF categories were identified as not-yet-included categories. CONCLUSIONS & IMPLICATIONS: This study contributes to the content validity of the Comprehensive ICF Core Set for MS from the perspective of SLTs. Study participants agreed on a few not-yet-included categories that should be further discussed for inclusion in a revised version of the Comprehensive ICF Core Set to strengthen SLTs' perspective in PwMS' neurorehabilitation.

Randomized pilot study: effects of an exercise programme and leucine supplementation in patients with cirrhosis.

BACKGROUND: Physical exercise could improve functional limitations, muscle mass, and health-related quality of life (HRQoL) in patients with cirrhosis. AIM: The purpose of this study was to evaluate the efficacy and safety of an exercise programme and leucine supplementation to increase exercise capacity, muscle mass, and HRQoL in patients with cirrhosis. PATIENTS AND METHODS: Seventeen outpatients with cirrhosis were randomized to an exercise group (n = 8) or a control group (n = 9) in a pilot study. The programme of moderate exercise was performed for 12 weeks under supervision of a physiotherapist. All patients received oral leucine (10 g/day) during the study. At baseline and at the end of the study, we determined exercise capacity (6-min walk and 2-min step tests), anthropometric measurements, and HRQoL by Short Form-36 (SF-36) questionnaire. We also analyzed safety regarding complications of cirrhosis, liver and renal function, inflammatory response and oxidative stress. RESULTS: In the exercise group, exercise capacity improved, as shown by the increase in the 6-min walk test from 365 (160-420) to 445 m (250-500) (p = 0.01), and in the 2-min step test (p = 0.02). Lower thigh circumference also increased, from 41 (34-53) to 46 cm (36-56) (p = 0.02), and the domains of SF-36 general health (p = 0.03), vitality (p = 0.01) and social function (p = 0.04) improved significantly. In the control group, no statistically significant changes were observed in any of the parameters. We did not observe complications of cirrhosis in either group during the study. CONCLUSIONS: A programme of moderate physical exercise together with leucine supplements in patients with cirrhosis is safe and improves exercise capacity, leg muscle mass and HRQoL.
