Telerehabilitation improves cardiorespiratory and muscular fitness and body composition in older people with post-COVID-19 syndrome.

BACKGROUND: The effects of post-coronavirus disease 2019 (COVID-19) syndrome on the cardiorespiratory and muscular fitness in older people are of utmost relevance. This study aimed to evaluate the effects of a 12-week telerehabilitation programme on cardiorespiratory and muscular fitness and body composition in older patients with post-COVID-19 syndrome. METHODS: One hundred twenty older patients with post-COVID-19 syndrome were randomly assigned to one of two groups: patients who carried out the telerehabilitation programme (n = 60; age: 65.0 ± 5.2; female: 14.2%) and a control group (n = 60; age: 64.3 ± 5.0; female: 24.5%). An incremental cardiopulmonary exercise testing, isokinetic strength test, and bioelectrical impedance analysis were performed to compare cardiorespiratory and muscle strength responses and body composition between telerehabilitation and control groups. RESULTS: A significant increase in the cardiopulmonary exercise testing duration was found in the telerehabilitation group compared to the control group (mean difference = 88.9 s, P = 0.001). Peak oxygen uptake increased in the telerehabilitation group (mean difference = 3.0 mL·kg-1·min-1, P < 0.001) and control group (mean difference = 1.9 mL·kg-1·min-1, P < 0.001). Power output in cycle ergometer (mean difference = 25.9 watts, P < 0.001), fat free mass (mean difference = 2.1 kg, P = 0.004), soft lean mass (mean difference = 2.1 kg, P = 0.003), and skeletal muscle mass (mean difference = 1.4 kg, P = 0.003) only increased in the telerehabilitation group. A significant increase in the power output was observed in the telerehabilitation group compared with the control group in both lower limbs after isokinetic strength test of the leg extension at a speed of 60° (right: mean difference = 18.7 watts, P = 0.012; left: mean difference = 15.3 watts, P = 0.010). The peak torque of right leg extension increased only in the telerehabilitation group after isokinetic strength test at a speed of 60° (mean difference = 13.1 N·m, P < 0.001). A significant increase in the power output was observed in the telerehabilitation group compared with the control group in the left leg extension after isokinetic strength test at a speed of 180° (mean difference = 30.2 watts, P = 0.003). CONCLUSIONS: The telerehabilitation programme improved cardiorespiratory and muscular fitness, and body composition in older patients with post-COVID-19 syndrome to a greater extent than a control group. The telerehabilitation programmes may be an alternative to improve the sequelae of post-COVID-19 syndrome in older patients.

Validation of the nutritrauma concept for the detection of potential harmful effects of medical nutritional treatment in critically ill patients in real life.

INTRODUCTION: medical nutritional treatment (MNT) can be complex and may be associated with potential metabolic complications, which has been recently described as nutritrauma. OBJECTIVE: the aim of our work is to describe whether the application of the nutritrauma concept in real life is feasible and useful to detect the metabolic complications associated with the prescription of MNT. MATERIAL AND METHODS: in this descriptive, prospective study at a single center we enrolled 30 consecutive critically ill patients in a 14-bed medical-surgical intensive care unit. The nutritrauma strategy implementation was based in four "M" steps: Metabolic screening, MNT prescription, biochemical Monitoring, and nutritional Management. RESULTS: we analyzed 28 patients (mean age, 69.7 ± 11.3 years; APACHE II, 18.1 ± 8.1; SOFA, 7.5 ± 3.7; Nutric Score, modified, 4.3 ± 2.01, and mean BMI, 27.2 ± 3.8). The main cause of admission was sepsis (46.4 %). Length of ICU stay was 20.6 ± 15.1 days; 39.3 % of subjects died during their ICU stay. Enteral nutrition (82.1 %) was more frequent than parenteral nutrition (17.9 %). During nutritional monitoring, 54 specific laboratory determinations were made. Hyperglycemia was the most frequent metabolic alteration (83.3 % of measurements). Electrolyte disturbances included hypocalcemia (50 %), hypophosphatemia (29.6 %) and hypokalemia (27.8 %). The most frequent lipid profile abnormalities were hypocholesterolemia (64.8 %) and hypertriglyceridemia (27.8 %). Furthermore, nutritional prescription was modified for 53.6 % of patients: increased protein dosage (25 %), increased calorie dosage (21.4 %) and change to organ-specific diet (17.8 %). CONCLUSIONS: in conclusion, the application of the nutritrauma approach facilitates detection of metabolic complications and an evaluation of the appropriate prescription of MNT.

[Effect of frailty in health resource use in aged cancer patients]. / Efecto de la fragilidad en el consumo de recursos sanitarios en ancianos con cáncer.

OBJECTIVE: To evaluate the effect of frailty on health resource use in aged population with cancer. METHOD: Population-based cohort study with retrospective data collection and follow-up from January 2018 to December 2019 in people ≥65 years with cancer. RESULTS: Overall, 996 individuals were included, with a prevalence of frailty of 22.1%. Mortality at 2 years was 14.1% in the frail and 9.0% in the non-frail (p=0.028). Independently of age and sex, frailty increased the number of urgent hospitalizations (168%) and planned hospitalizations (64%), visits to the emergency room (111%), outpatient consultations (59%), day hospital sessions (30%) and visits to primary care (114%). CONCLUSIONS: Frailty is more prevalent, determines a poorer prognostic and is associated with higher health resource use in aged population with cancer.

Effect of frailty on postoperative complications, mortality, and survival in older patients with non-metastatic colon cancer: A systematic review and meta-analysis.

INTRODUCTION: New evidence has emerged on the impact of frailty on prognosis in colon cancer, but the findings are not always consistent and conclusive. The aim of this systematic review was to assess the effect of frailty on postoperative complications and mortality in patients with non-metastatic colon cancer (CC) aged 65 years and older. MATERIALS AND METHODS: We systematically searched for original studies published in the PubMed and Web of Science databases up to June 2021. Two independent reviewers selected the studies and extracted predefined data. A meta-analysis was performed using the random effects model to assess the effect of frailty on 30-day, 3- to 6-month and 1-year mortality, survival, and postoperative complications. RESULTS: The search yielded 313 articles, of which 14 were included in this systematic review. The meta-analysis showed an effect for frailty on 30-day, 3- to 6-month, and 1-year mortality with respective pooled odds ratios (ORs) of 3.67 (95% confidence interval [CI] 1.53-8.79, p = 0.004), 8.73 (95% CI 4.03-18.94, p < 0.0001), and 3.99 (95% CI 2.12-7.52, p < 0.0001). Frailty also had an effect on survival, with a pooled hazard ratio of 2.99 (95% CI 1.70-5.25. p < 0.0001), and on overall and severe postoperative complications with pooled ORs of 2.34 (95% CI 1.75-3.15; p < 0.0001) and 2.43 (95% CI 1.72-3.43; p < 0.0001), respectively. DISCUSSION: Frailty in older patients with CC is a risk factor for postoperative complications and mortality in the short term (30 days), medium term (3-6 months), and long term (1 year).

Effect of different types of supervised exercise programs on cardiorespiratory and muscular fitness, pain, fatigue, mental health and inflammatory and oxidative stress biomarkers in older patients with post-COVID-19 sequelae "EJerSA-COVID-19": a randomized controlled trial.

BACKGROUND: Many patients with COVID-19 present the so-called post-acute sequelae of COVID-19 such as fatigue, post-stress discomfort, dyspnea, headache, pain mental impairment, incapacity to perform daily physical tasks ant exercise intolerance. This study aims to investigate the effects of different exercise programs on physical and mental fitness, physical condition and biomarkers of the immune system and oxidative stress in older patients with post-COVID-19 sequelae. METHODS: The sample will be made up of 120 eligible participants, over the age of 60 years who have had COVID-19 disease and are survivors and present persistent COVID-19 symptomatology diagnosed by the corresponding physician. The participants will be randomly assigned to the experimental groups: supervised endurance group (SEG, n = 30), supervised strength group (SSG, n = 30), supervised concurrent group (SCG, n = 30), which will perform the corresponding exercise program 3 days a week compared to the control group (CG, n = 30), which will not carry out a supervised exercise program. The design of this project will include measurements of four relevant dimensions; 1) Cardiorespiratory fitness; 2) Muscle fitness; 3) Pain and mental health; and 4) Biomarkers of inflammation and oxidative stress. CONCLUSIONS: The results of this study will provide insights into the effects of different exercise programs on physical and mental fitness, physical condition and biomarkers of the immune system and oxidative stress in older patients with post-COVID-19 sequelae. These findings may be the basis for the formulation of health plans and rehabilitation programs that allow healthy aging and a reduction in the associated morbidity in patients with post-COVID-19 sequelae.

Relationship between Hydration Status and Muscle Catabolism in the Aged Population: A Cross-Sectional Study.

BACKGROUND: The physiopathology of sarcopenia is still not completely understood. AIM: To assess the relationship between dehydration and skeletal muscle catabolism, muscle mass, and sarcopenia in an aged population. METHODS: Observational cross-sectional study of community-dwelling subjects aged 70 years and older. Dehydration was assessed by plasma osmolarity; bioimpedance analysis (BIA) was used to assess body composition and water content; sarcopenia was established according to the EWGSOP-2 criteria; and 3-methyl-histidine (3MH) was used as an indicator of muscle catabolism. RESULTS: 190 participants were recruited (77.4 years; 51.6% women). In total, 22.6% and 20.5% presented plasma osmolarity of 295-300 mOsm/L and >300 mOsm/L, respectively. Age was correlated with plasma osmolarity (rs = 0.439; p < 0.001). Plasma osmolarity was correlated with 3MH (rs = 0.360; p < 0.001) and showed an effect on 3MH levels, with an adjusted (by age, sex, and number of medications) beta of 0.283 (p < 0.001). BIA water content indicators showed no correlation with 3MH. Lower in sarcopenic compared to non-sarcopenic subjects were the intracellular water percentage (60.3 vs. 61.2%; p = 0.004) and intracellular water/free-fat mass ratio (44.3 vs. 45.0; p = 0.004). CONCLUSIONS: Dehydration is a highly prevalent clinical condition in aged populations, increases with age, and is associated with muscle catabolism but not sarcopenia.

Relationship of frailty status with health resource use and healthcare costs in the population aged 65 and over in Catalonia.

BACKGROUND: Frailty is a geriatric syndrome with repercussions on health, disability, and dependency. OBJECTIVES: To assess health resource use and costs attributable to frailty in the aged population. METHODS: A population-based observational longitudinal study was performed, with follow-up from January 2018 to December 2019. Data were obtained retrospectively from computerized primary care and hospital medical records. The study population included all inhabitants aged ≥ 65 years ascribed to 3 primary care centres in Barcelona (Spain). Frailty status was established according to the Electronic Screening Index of Frailty. Health costs considered were hospitalizations, emergency visits, outpatient visits, day hospital sessions, and primary care visits. Cost analysis was performed from a public health financing perspective. RESULTS: For 9315 included subjects (age 75.4 years, 56% women), frailty prevalence was 12.3%. Mean (SD) healthcare cost in the study period was €1420.19 for robust subjects, €2845.51 for pre-frail subjects, €4200.05 for frail subjects, and €5610.73 for very frail subjects. Independently of age and sex, frailty implies an additional healthcare cost of €1171 per person and year, i.e., 2.25-fold greater for frail compared to non-frail. CONCLUSIONS: Our findings underline the economic relevance of frailty in the aged population, with healthcare spending increasing as frailty increases.

Prevalence and risk factors of SARS-CoV-2 antibody responses among healthcare workers (June 2020-November 2021).

BACKGROUND: To assess SARS-CoV-2 seroprevalence in healthcare workers (HCW) with sampling in June and October 2020 and April and November 2021. METHODS: Observational and prospective study in 2455 HCW with serum sampling. Antibodies against SARS-CoV-2 nucleocapsid and occupational, social and health risk factors were assessed at each time point. RESULTS: Seropositivity for SARS-CoV-2 in HCW increased from 11.8% in June 2020 to 28.4% in November 2021. Of those with a positive test in June 2020, 92.1% remained with a positive test, 6.7% had an indeterminate test and 1.1% had a negative test in November 2021. Non-diagnosed carriers represented 28.6% in June 2020 and 14.6% in November 2021. Nurses and nursing assistants showed the highest prevalence of seropositivity. Close contact (at home or in the hospital) with Covid-19 cases without protection and working in the frontline were the main risk factors. A total of 88.8% HCW were vaccinated, all with a positive serological response in April 2021, but levels of antibodies decreased about 65%, and two vaccinated persons presented a negative serological test against spike protein in November 2021. Levels of spike antibodies were higher in those vaccinated with Moderna compared with Pfizer and the percentage of antibody reduction was higher with Pfizer vaccine. CONCLUSIONS: This study shows that seroprevalence of SARS-CoV-2 antibodies among HCW doubled that of the general population and that protection both at the workplace and in the socio-familial field was associated with a lower risk of infection, which stabilized after vaccination.

Economic Evaluation of Clinical, Nutritional and Rehabilitation Interventions on Oropharyngeal Dysphagia after Stroke: A Systematic Review.

BACKGROUND: Post-stroke oropharyngeal dysphagia (PS-OD) and its complications increase healthcare costs, suggesting that its appropriate management is cost-effective. We aimed to assess the efficiency of healthcare interventions in PS-OD management. METHODS: A systematic review was conducted following PRISMA recommendations. Four databases were searched from inception through 30 June 2021. Outcome measures were cost-effectiveness and cost-savings of healthcare interventions. English and Spanish literature were included. Narrative and tables were used to present and synthesise evidence. Quality was evaluated using the CHEERS Statement. RESULTS: A total of 244 studies were identified, and 10 were included. Screening and diagnosis of PS-OD studies found: (1) adjusted reduction in hospitalisation costs when assessed during the first admission day; (2) non-significant reduction in hospitalisation costs with OD management after thrombolysis; and (3) videofluoroscopy as the most cost-effective screening method (compared to bedside evaluation and a combination of both). Two studies showed cost-effective rehabilitation programmes, including OD management. Pelczarska et al. showed an incremental cost-utility ratio of texture-modified diets using a gum-based thickener of 20,977 PLN (4660€) following a dynamic model, and Kotecki et al. commercially prepared thickened fluids that were 44% to 59% less expensive than in situ prepared fluids. Elia et al. showed home enteral nutrition was cost-effective (£12,817/QALY), and Beavan et al. showed higher nutrient intake and low increase in hospitalisation costs using looped-nasogastric tubes (£5.20 for every 1% increase). Heterogeneity between studies precluded a quantitative synthesis. CONCLUSIONS: Included studies suggest that healthcare interventions aiming to prevent OD complications are cost-effective. However, studies assessing novel strategies are needed.

Real-world effectiveness and durability of dual antiretroviral therapy in HIV-infected patients.

BACKGROUND AND OBJECTIVES: While randomised controlled trials in HIV-infected patients have shown that certain dual antiretroviral therapy (DAT) regimens are non-inferior in terms of efficacy compared with classical triple-drug regimens, few real clinical experiences have been described. The aim of the study was to investigate, in real clinical practice, DAT effectiveness, durability, and risk factors for treatment discontinuation. METHODS: This was a prospective cohort study that included HIV-infected patients treated with DAT (2015-2020). DAT was considered effective when patients achieved or maintained virological suppression and was assessed at 24 and 48 weeks. DAT durability was evaluated using the Kaplan-Meier method. Adherence and treatment cost were compared with patients' previous antiretroviral regimens. RESULTS: 51 patients were included, 27.5% with HIV-1 RNA ≥50 copies/mL at baseline, treated with a wide range of dual combinations. At 48 weeks follow-up, 83.8% and 50.0% of patients who started DAT with HIV-1 RNA <50 copies/mL and ≥50 copies/mL, respectively, were suppressed. 39 out of 51 patients (76.5%) maintained DAT for a mean treatment duration of 40.5±14.8 weeks. Full adherence was observed in 78.4% of patients compared with 70.2% in the previous regimen. Mean daily cost was €18.6±4.3 compared with €16.1±7.9 in the previous regimen (p=0.008). CONCLUSION: DAT effectiveness and durability were higher in patients who were virologically suppressed at baseline. DAT is a possible alternative for virologically non-suppressed patients who cannot be treated with a triple-drug regimen.

Development and validation of the electronic screening index of frailty.

BACKGROUND: primary care screening for frailty status is recommended in clinical guidelines, but is impeded by doctor and nurse workloads and the lack of valid, easy-to-use and time-saving screening tools. AIM: to develop and validate a new electronic tool (the electronic screening index of frailty, e-SIF) using routinely available electronic health data to automatically and massively identify frailty status in the population aged ≥65 years. METHODS: the e-SIF was developed in three steps: selection of clinical conditions; establishment of ICD-10 codes, criteria and algorithms for their definition; and electronic tool design and data extraction, transformation and load processes. The validation phase included an observational cohort study with retrospective data collection from computerised primary care medical records. The study population included inhabitants aged ≥65 years corresponding to three primary care centres (n = 9,315). Evaluated was the relationship between baseline e-SIF categories and mortality, institutionalisation, hospitalisation and health resource consumption after 2 years. RESULTS: according to the e-SIF, which includes 42 clinical conditions, frailty prevalence increases with age and is slightly greater in women. The 2-year adjusted hazard ratios for pre-frail, frail and very frail subjects, respectively, were as follows: 2.23 (95% CI: 1.74-2.85), 3.34 (2.44-4.56) and 6.49 (4.30-9.78) for mortality; 2.80 (2.39-3.27), 5.53 (4.59-6.65) and 9.14 (7.06-11.8) for hospitalisation; and 1.02 (0.70-1.49), 1.93 (1.21-3.08) and 2.69 (1.34-5.40) for institutionalisation. CONCLUSIONS: the e-SIF shows good agreement with mortality, institutionalisation, hospitalisation and health resource consumption, indicating satisfactory validity. More studies in larger populations are needed to corroborate our findings.

Economic evaluations of health care interventions in oropharyngeal dysphagia after stroke: protocol for a systematic review.

BACKGROUND AND PURPOSE: Oropharyngeal dysphagia (OD) affects 40-81% of patients after stroke. A recent systematic review on the costs of OD and its main complications showed higher acute and long-term costs for those patients who developed OD, malnutrition and pneumonia after stroke. These results suggest that appropriate management of post-stroke OD could reduce clinical complications and costs. The purpose of this systematic review is to assess the available literature for healthcare interventions that are efficient or cost-effective in the management of OD. METHODS: A systematic review on economic evaluations of health care interventions will be performed on post-stroke patients with OD following PRISMA recommendations. Four bibliographic databases will be searched and a subsequent reference check will be done. English and Spanish literature will be included without date restrictions. Studies will be included if they refer to economic evaluations or in which cost savings were reported in post-stroke patients suffering OD. Studies will be excluded if they are partial economic evaluation studies, if they refer to esophageal dysphagia, or if OD is caused by causes different from stroke. Evidence will be presented and synthetised with a narrative method and using tables. Quality evaluation will be done using the Consolidated Health Economic Evaluation Reporting Standards (CHEERS) statement. DISCUSSION: The protocol for this systematic review is the first step to assess the cost-effectiveness of the healthcare interventions that have been described as potential treatments for post-stroke OD. This systematic review will summarise the current evidence on the relation between cost and benefits associated with the appropriate management of OD in post-stroke patients.

Depressive symptom severity is a major risk factor for frailty in community-dwelling older adults with depression. A prospective study.

BACKGROUND: Depression and frailty are closely related, but the mechanisms by which depressed older adults are at an increased risk of becoming frail are still not well understood. AIM: To assess socioeconomic and depression-related risk factors for frailty in older adults with depression. METHODS: Observational and prospective cohort study, with 12-month follow-up, of nonfrail community-dwelling subjects aged ≥70 years old with depression. The main study factors were clinical characteristics of depression, including symptom severity (Hamilton Depression Rating Scale), accompanying anxiety and cognitive symptoms, pharmacological treatment, and social factors including educational level, income, housing conditions and living circumstances, and social network. Frailty status was established according to Fried criteria. RESULTS: We recruited and analysed 216 subjects (mean age 76.5 years; 74% women), 65 (30%) of whom were lost to follow-up. Annual incidence of frailty was 23.2 new cases/100 persons. Age, female gender, osteoarthritis, pain, number of medications, major depression, first-degree family history of depression, depressive symptom severity, low educational level, and low-income level were risk factors for frailty. The multivariate analysis showed that age (odds ratio [OR] = 1.16; 95% confidence interval [CI]: 1.04-1.29), visual analogue scale (VAS)-pain (OR = 1.25; 95% CI: 1.01-1.55), and severe or very severe depressive symptoms (OR = 37.36; 95% CI: 2.68-518.53) were significantly associated with incident frailty at 12 months of follow-up. CONCLUSIONS: Both clinical and social characteristics are risk factors for frailty, but severity of depressive symptoms had the highest independent effect on frailty in depressed aged subjects. Frailty requires a multidisciplinary approach that pays special attention to pain and depressed mood.

Functional Constipation in Older Adults: Prevalence, Clinical Symptoms and Subtypes, Association with Frailty, and Impact on Quality of Life.

INTRODUCTION: Functional constipation (FC) is very prevalent in older adults, especially in women, but its relationship with frailty is not fully understood. The aims were to assess FC prevalence, clinical symptoms and subtypes, association with frailty, and impact on quality of life (QoL) in older people. METHODS: This epidemiological study included 384 individuals aged over 70 years recruited from the community, a hospital, and a nursing home and stratified into robust, pre-frail, and frail groups (Fried criteria). The following criteria were evaluated: frailty, FC (Rome III criteria), stool consistency (Bristol Stool Chart), comorbidities (Charlson), dependency (Barthel), QoL (EQ5D), and clinical and sociodemographic data. Defined by symptom aggregation were 2 main clinical subtypes as follows: slow colonic transit time (CTT) and functional defecation disorder (FDD). RESULTS: Mean age was 79.11 ± 6.43 years. Overall FC prevalence was 26.8%, higher in women (32.4% women vs. 21.8% men; p = 0.019) and highest in frail patients (41.7% frail vs. 33.9% pre-frail vs. 24.2% robust; p < 0.001). Straining and hard stools (Bristol 1-2) were the most prevalent symptoms (89.3 and 75.7%, respectively). Frailty and benzodiazepine intake were independently associated with FC. Patients with FC obtained poorer QoL scores in the EQ5D (perceived health 66.09 ± 17.8 FC patients vs. 56.4 ± 19.03 non-FC patients; p < 0.05). The FDD subtype became significantly more prevalent as frailty increased (6.5, 25.8, and 67.7% for robust, pre-frail, and frail patients, respectively); the slow CTT subtype was significantly more frequent in robust patients (38.5% robust vs. 30.5% pre-frail vs. 23.1% frail), p = 0.002. DISCUSSION/CONCLUSION: FC prevalence in older adults was high, especially in women, and was associated with frailty and poor QoL. Clinical subtypes as related to frailty phenotypes reflect specific pathophysiological aspects and should lead to more specific diagnoses and improved treatment.

A Systematic and a Scoping Review on the Psychometrics and Clinical Utility of the Volume-Viscosity Swallow Test (V-VST) in the Clinical Screening and Assessment of Oropharyngeal Dysphagia.

(1) Background: The volume-viscosity swallow test (V-VST) is a clinical tool for screening and diagnosis of oropharyngeal dysphagia (OD). Our aims were to examine the clinical utility of the V-VST against videofluoroscopy (VFS) or fiberoptic endoscopic evaluation of swallow (FEES) and to map the V-VST usage with patients at risk of OD across the years since it was described for the first time, carrying a systematic and a scoping review. (2) Methods: We performed both a systematic review (SR) including studies that look at the diagnostic test accuracy, and a scoping review (ScR) with articles published from September 2008 to May 2020. Searches were done in different databases, including PubMed and EMBASE from September 2008 until May 2020, and no language restrictions were applied. A meta-analysis was done in the SR to assess the psychometric properties of the V-VST. Quality of studies was assessed by Dutch Cochrane, QUADAS, GRADE (SR), and STROBE (ScR) criteria. The SR protocol was registered on PROSPERO (registration: CRD42020136252). (3) Results: For the diagnostic accuracy SR: four studies were included. V-VST had a diagnostic sensitivity for OD of 93.17%, 81.39% specificity, and an inter-rater reliability Kappa = 0.77. Likelihood ratios (LHR) for OD were 0.08 (LHR-) and 5.01 (LHR+), and the diagnostic odds ratio for OD was 51.18. Quality of studies in SR was graded as high with low risk of bias. In the ScR: 34 studies were retrieved. They indicated that V-VST has been used internationally to assess OD's prevalence and complications. (4) Conclusions: The V-VST has strong psychometric properties and valid endpoints for OD in different phenotypes of patients. Our results support its utility in the screening and clinical diagnosis and management of OD.

Healthcare costs of post-stroke oropharyngeal dysphagia and its complications: malnutrition and respiratory infections.

BACKGROUND AND PURPOSE: The healthcare economic costs of post-stroke oropharyngeal dysphagia (OD) are not fully understood. The purpose of this study was to assess the acute, subacute and long-term costs related to post-stroke OD and its main complications (malnutrition and respiratory infections). METHODS: A cost of illness study of patients admitted to Mataró Hospital (Catalonia, Spain) from May 2010 to September 2014 with a stroke diagnosis was performed. OD, malnutrition and respiratory infections were assessed during hospitalization and follow-up (3 and 12 months). Hospitalization and long-term costs were measured from hospital and healthcare system perspectives. Multivariate linear regression analysis was performed to assess the independent effect of OD, malnutrition and respiratory infections on healthcare costs during hospitalization, and at 3 and 12 months' follow-up. RESULTS: In all, 395 patients were included of whom 178 had OD at admission. Patients with OD incurred major total in-hospital costs (€5357.67 ± €3391.62 vs. €3976.30 ± €1992.58, p < 0.0001), 3-month costs (€8242.0 ± €5376.0 vs. €5320.0 ± €4053.0, p < 0.0001) and 12-month costs (€11,617.58 ± €12,033.58 vs. €7242.78 ± €7402.55, p < 0.0001). OD was independently associated with a cost increase of €789.68 (p = 0.011) during hospitalization and of €873.5 (p = 0.084) at 3 months but not at 12 months. However, patients with OD who were at risk of malnutrition or malnourished and suffered respiratory infections incurred major mean costs compared with those patients without OD (€19,817.58 ± €13,724.83 vs. €7242.8 ± €7402.6, p < 0.0004) at 12 months' follow-up. CONCLUSION: Oropharyngeal dysphagia causes significant high economic costs during hospitalization that strongly and significantly increase with the development of malnutrition and respiratory infections at long-term follow-up.

Psychosocial factors associated with frailty in the community-dwelling aged population with depression. A cross-sectional study / Factores psicosociales asociados a fragilidad en ancianos de la comunidad con depresión: estudio observacional transversal

Objective: There is a two-way relationship between frailty and depression, but the mechanisms by which one may influence the other are not well understood. The objective of this study was to evaluate the relationship between psychosocial factors and frailty in community-dwelling aged populations with depression. Design:Observational cross-sectional study. Site: 5 primary care centres. Participants: Community-dwelling subjects with depression aged ≥70 years. Main measurements: Frailty status was established according to Fried criteria, depression and depression severity were evaluated by DSM-IV criteria and the Hamilton Depression Rating Scale, respectively, and psychosocial factors were assessed using the Gijón Social-Familial Evaluation Scale and ad hoc questionnaires. Results: Recruited were 338 subjects (mean age 77.2 years), 82% women and 36.1% rated as frail. A dose–response relationship was observed between depression severity and frailty risk. Widowhood was a risk factor for frailty, while a higher educational level, home internet, stairs in the home, and an active social life had a protective effect. A multivariate analysis showed that age, number of drugs, and depression severity were independent risk factors for frailty, while an active social life was a protective factor. The severity of depressive symptoms showed higher association with frailty than other clinical and socio-demographic characteristics. Conclusions: In depressed elderly subjects, frailty is associated with psychologiocal factors such as the intensity of depressive symptoms and with social factors such as education level, widowhood, loneliness, and limited social life. More research is required to better understand the modifiable psychological risk factors for frailty.(AU)

Objetivo: Existe una relación bidireccional entre la fragilidad y la depresión en la población anciana. El objetivo de este estudio fue evaluar la relación entre los factores psicosociales y la fragilidad en ancianos de la comunidad con depresión. Diseño: Estudio observacional transversal. Sitio: Cinco centros de atención primaria. Participantes: Ancianos ≥70años de la comunidad con depresión. Principales mediciones: La fragilidad se estableció de acuerdo con los criterios de Fried, la depresión y la gravedad de la depresión se evaluaron mediante los criterios DSM-IV y la Escala de Hamilton, respectivamente, y los factores psicosociales se evaluaron utilizando la Escala de Evaluación Social-Familiar de Gijón y cuestionarios ad hoc. Resultados: Se reclutaron 338 sujetos (edad media 77años), 82% mujeres y 36,1% frágiles. Se observó una relación dosis-respuesta entre la gravedad de la depresión y el riesgo de fragilidad. La viudez era un factor de riesgo para la fragilidad, mientras que un nivel educativo más alto, internet en el hogar, escaleras en el hogar y una vida social activa tenían un efecto protector. El análisis multivariado mostró que la edad, el número de medicamentos y la gravedad de la depresión eran factores de riesgo independientes para la fragilidad, mientras que una vida social activa era un factor protector. Conclusiones: En ancianos con depresión la fragilidad se asocia con factores psicológicos como la intensidad de los síntomas depresivos y con factores sociales como el nivel de estudios, la viudez, la soledad o la escasa vida social. Se requiere más investigación para comprender mejor los factores de riesgo psicológicos modificables de fragilidad.(AU)
