[Effect of frailty in health resource use in aged cancer patients]

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.

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.

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.

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.

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.

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.

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.

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.

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

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.

Effectiveness of a Weight-Loss Intervention in Preventing Frailty and Functional Decline in Community-Dwelling Obese Older People. A Randomized Controlled Trial

Background: Obesity is a risk factor for frailty and muscle weakness, so weight loss in obese older adults may prevent frailty and functional decline. Objective: To assess the safety and efficacy of a multimodal weight-loss intervention in improving functional performance and reducing frailty risk in obese older adults. Design: Randomized controlled trial with 2 parallel arms. Setting and participants: Community-dwelling obese adults aged 65-75 years with body mass index (BMI) 30-39 kg/m2. Intervention: 6-month multimodal intervention based on diet and a physical activity program. Control group: Usual care. Main and secondary outcome measures: Frailty (Fried criteria) rate and functional performance at 6, 12, and 24 months of follow-up, respectively. Intermediate outcome measures: Weight loss, body composition changes, and metabolic and inflammatory biomarker changes. Results: N=305. The study intervention increased gait speed at 12 and 24 months of follow-up, but had no significant effect on frailty prevention. It was effective in reducing weight, BMI, fat mass, interleukin 6, and insulin resistance and improving self-reported quality of life. Conclusions: The study intervention was not demonstrated to be effective in preventing frailty in obese people aged 65-75 years at 24 months of follow-up. However, it allowed weight loss and a reduction in inflammatory and insulin resistance markers, which could have a long-term effect on frailty that requires further research.

Prevalence, incidence and risk factors for foot pressure ulcers in hospitalized elderly patients. An observational and prospective study

BACKGROUND

Incidence and clinical characteristics of foot pressure ulcers (FPU) in hospitalized elderly patients are not well known. The aim of the study was to determine the incidence of FPU during hospitalization, to describe main FPU characteristics and to assess main risk factors for FPU in hospitalised elderly subjects.

METHODOLOGY

An observational prospective study was performed in which patients 65 years or older admitted to Vascular Surgery, Orthopaedic or Geriatric departments were followed from admission to discharge. Trained nurses evaluated all recruited patients on a daily basis for possible FPU. Main characteristics of the patient (age, sex and co-morbidities) and the ulcer (location, grade) were registered.

RESULTS

299 patients were recruited (62.2% women, mean age 82.3 years, mean number of co-morbidities 2.8). Prevalence of FPU was 30.1% at admission and 73.9% at discharge. Incidence of FPU during hospitalization was 9.5 new FPU/100 person-day. 97.0% of the new FPU were grade 1 (erythema) and the most common locations were in the heel (57.6%), the external lateral part of the foot (13.1%), and the hallux of the fist toe (11.8%). Apart from immobility, main risk factors for FPU are age, geriatric residence origin and not able to outdoor life.

CONCLUSIONS

FPU has a high incidence among hospitalised elderly patients; most of them are grade 1 and located in the heel. More attention must be paid in the prevention of pressure ulcers in hospitalized frail subjects.

The Experience of COPD Patients in Lockdown Due to the COVID-19 Pandemic

Purpose

On March 16, 2020, the Spanish government declared a state of alarm due to the rapid spread of coronavirus disease 2019 (COVID-19). Patients with chronic obstructive pulmonary disease (COPD) were restricted to remain confined at home, and medical visits were cancelled for 3 months. The impact of this lockdown on the manifestations of COPD and the quality-of-life of these patients has not been explored.

Patients and Methods

One hundred patients with COPD were interviewed by telephone from May 2–18, 2020. The interviews included questions about the lockdown, missed medical appointments, fears of the disease, possible COVID-19 infection, and exacerbations of COPD suffered during this period and their management. In addition, the COPD Assessment Test, the Hospital Anxiety and Depression, and the 5-Dimension Euro Quality-of-Life questionnaires were administered.

Results

Sixty-four (64%) patients claimed to have strictly complied with the lockdown, and only 42 (42%) stated they had left home at least once during lockdown. Only one patient (1%) was hospitalized due to COVID-19, and 13 (13%) patients presented an exacerbation of COPD self-managed at home with no admissions due to exacerbation of COPD during this period. A medical consultation or complementary test was cancelled in 90% of the patients, but 61% had a medical telephone visit with a high degree of satisfaction (mean 9.3/10). Most patients declared that their feeling regarding lung disease and general health was similar or even better during lockdown (82% and 81%, respectively).

Conclusion

Our results indicate that in general lockdown had a low impact on COPD patients. Only one patient was affected by COVID-19, but moderate exacerbations of COPD were not infrequent. Although many medical visits and test were cancelled, patients were very satisfied with the medical telephone visits.

MEDLINE, Embase and the National Health Service Economic Evaluation Database were searched up to 31 December 2019.

PARTICIPANTS

Patients with poststroke.

PRIMARY OUTCOME MEASURES

The costs associated to poststroke OD and its complications.

DATA ANALYSIS

Data were synthetised narratively, quality evaluation was done using an adaptation of Drummond's checklist and Grading of Recommendations Assessment, Development and Evaluation recommendations were used to assess strength of evidence.

RESULTS

A total of 166 articles were identified, of which 10 studies were included. The cost of OD during the hospitalisation was assessed in four studies. One prospective study showed an increase of US$6589 for patients requiring tube feeding. Two retrospective studies found higher costs for those patients who developed OD, (US$7329 vs US$5939) among patients with haemorrhagic stroke transferred to inpatient rehabilitation and an increase of €3000 (US$3950) and SFr14 000 (US$15 300) in hospitalisation costs. One study did not found OD as a predictor for total medical costs in the multivariate analysis. One retrospective study showed an increase of US$4510 during the first year after stroke for those patients with OD. For pneumonia, five retrospective studies showed an increase in hospitalisation costs after stroke of between US$1456 and US$27 633. One prospective study showed an increase in hospitalisation costs during 6 months after stroke in patients at high malnutrition risk. Strength of evidence was considered moderate for OD and pneumonia and low for malnutrition.

CONCLUSIONS

This systematic review shows moderate evidence towards higher costs for those patients who developed OD after stroke. The available literature is heterogeneous, and some important aspects have not been studied yet. Further studies are needed to define the specific cost of poststroke OD.

Intracellular Water Content in Lean Mass as an Indicator of Muscle Quality in an Older Obese Population

Background: In aged populations, muscle strength depends more on muscle quality than on muscle quantity, while all three are criteria for the diagnosis of sarcopenia. Intracellular water content (ICW) in lean mass (LM) has been proposed as an indicator of muscle quality related to muscle strength in older people. Objectives: To evaluate the relationship between the ICW/LM ratio, muscle strength and indicators of functional performance in obese older adults, and to assess the value of the ICW/LM ratio as an indicator of muscle quality. Methodology: Design: cross-sectional study. Population: persons aged 65–75 years with a body mass index of 30–39 kg/m². ICW and LM were estimated by bioelectrical impedance. Hand grip, gait speed, unipedal stance test, timed up-and-go (TUG) test, Barthel score and frailty (Fried criteria) were assessed. Sarcopenia was established according to EWGSOP2 criteria. Results: Recruited were 305 subjects (66% women), mean age 68 years. The ICW/LM ratio correlated with the TUG test, gait speed and grip strength, and was also associated with sex, the unipedal stance test and frailty. Independently of age, sex and muscle mass, the ICW/LM ratio was related with gait speed, the TUG test and unipedal stance capacity. One person (0.3%) had sarcopenia defined as low muscle strength and low muscle mass, while 25 people (8.2%) had sarcopenia defined as low muscle strength and poor muscle quality (ICW/LM). With this last definition, sarcopenia was related to frailty, gait speed and the TUG test. Conclusions: ICW content in LM could be a useful muscle quality indicator for defining sarcopenia. However, more studies are required to confirm our findings for other populations.

Intracellular Water Content in Lean Mass is Associated with Muscle Strength, Functional Capacity, and Frailty in Community-Dwelling Elderly Individuals. A Cross-Sectional Study

High intracellular water (ICW) content has been associated with better functional performance and a lower frailty risk in elderly people. However, it is not clear if the protective effect of high ICW is due to greater muscle mass or better muscle quality and cell hydration. We aimed to assess the relationship between ICW content in lean mass (LM) and muscle strength, functional performance, frailty, and other clinical characteristics in elderly people. In an observational cross-sectional study of community-dwelling subjects aged ≥75 years, ICW and LM were estimated by bioelectrical impedance, and the ICW/LM ratio (mL/kg) calculated. Muscle strength was measured as hand grip, frailty status was assessed according to Fried criteria, and functional status was assessed by Barthel score. For 324 recruited subjects (mean age 80 years), mean (SD) ICW/LM ratio was 408 (29.3) mL/kg. The ICW/LM ratio was negatively correlated with age (r_s = −0.249; p < 0.001). A higher ICW/LM ratio was associated with greater muscle strength, better functional capacity, and a lower frailty risk, even when adjusted by age, sex, nº of co-morbidities, and LM. ICW content in LM (including the muscle) may influence muscle strength, functional capacity and frailty. However, further studies are needed to confirm this hypothesis.

Total Body Water and Intracellular Water Relationships with Muscle Strength, Frailty and Functional Performance in an Elderly Population

BACKGROUND

As a person ages, total body water (TBW), intracellular water (ICW), muscle mass and muscle strength tend to decline. The decline in ICW may reflect losses in the number of muscle cells but may also be responsible for less hydrated muscle cells.

AIM

To assess whether TBW and ICW are associated with muscle strength, functional performance and frailty in an aged population, independently of muscle mass.

METHODOLOGY

Design: An observational cross-sectional study of community-dwelling individuals aged 75 years and older. TBW, ICW, fat mass, lean mass and muscle mass were assessed by bioelectrical impedance analysis, frailty status was measured according to Fried criteria, handgrip strength was measured using the hand-held JAMAR dynamometer, and functional performance was measured according to the Barthel index and gait speed.

RESULTS

A total of 324 subjects were recruited (mean age 80.1 years, 47.5% women). TBW and ICW were closely correlated with muscle mass in both sexes. ICW was also associated with Barthel score, gait speed and frailty in both sexes and with handgrip in men. Considerable variability in ICW was observed for the same muscle mass. Multivariate analysis showed a positive effect of ICW on handgrip, functional performance and gait speed and a protective effect of ICW on frailty, independently of age, sex, body mass index and number of comorbidities.

CONCLUSIONS

In elderly individuals with similar muscle mass, those with higher ICW had a better functional performance and a lower frailty risk, suggesting a protective effect of cell hydration, independently of muscle mass.

Cost of oropharyngeal dysphagia after stroke: protocol for a systematic review

INTRODUCTION

Oropharyngeal dysphagia (OD) is a major disorder following stroke. OD can produce alterations in both the efficacy and safety of deglutition and may result in malnutrition, dehydration, frailty, respiratory infections and pneumonia. These complications can be avoided by early detection and treatment of OD in poststroke patients, and hospital stays, medication and mortality rates can be reduced. In addition to acute in-hospital costs from OD complications, there are other costs related to poststroke OD such as direct non-healthcare costs or indirect costs. The objective of this systematic review is to assess and summarise literature on the costs related to OD in poststroke patients.

METHODS AND ANALYSIS

A systematic review of studies on the cost of OD and its complications (aspiration, malnutrition, dehydration, aspiration pneumonia and death) in patients who had a stroke will be performed from the perspectives of the hospital, the healthcare system and/or the society. The main outcomes of interest are the costs related to poststroke OD. We will search MEDLINE, Embase and the National Health Service Economic Evaluation Database. Studies will be included if they are partial economic evaluation studies, studies that provide information on costs in adult (>17 years) poststroke patients with OD and/or its complications (malnutrition, dehydration, frailty, respiratory infections and pneumonia) or economic evaluation studies in which the cost of this condition has been estimated. Studies will be excluded if they refer to oesophageal dysphagia or OD caused by causes other than stroke. Main study information will be presented and summarised in tables, separately for studies that provide incremental costs attributable to OD or its complications and studies that report the effect of OD or its complications on total costs of stroke, and according to the perspective from which costs were measured.

ETHICS AND DISSEMINATION

The results of this systematic review will be published in a peer-reviewed journal.

Short-term foot complications in Charcot neuroarthropathy: A retrospective study in tertiary care centres in Spain

OBJECTIVES

To assess the clinical characteristics of patients with Charcot neuroarthropathy (CN) in Spain and to identify predictors for CN-related complications.

PATIENTS AND METHODS

A retrospective study was conducted at five tertiary hospitals with diabetic foot care units in Spain. Data were collected from 83 patients, including demographic profiles, foot factors, diabetes characteristics, and presence of microvascular and macrovascular comorbidity, and a podiatric examination was also performed. Logistic regression analyses were used to determine significant predictors of the predefined clinical events.

RESULTS

Signs of diabetic neuropathy were found in almost all patients (98.9%) at the initial assessment, approximately half of them had diabetic retinopathy or nephropathy (61.5% and 51.8%, respectively), and peripheral artery disease was uncommon (8.6%). Thirty-eight patients (47.5%) experienced one or more relevant clinical events: 22 (27.5%) a new foot ulcer; 7 (8.7%) a major amputation; 20 (25%) were admitted to hospital; and 4 (5%) died. Only the presence of diabetic nephropathy was independently associated to development of any of the complications studied (p = 0.009; odds ratio = 3.37; 95% CI: 1.12-10.1).

CONCLUSIONS

Almost half the patients with CN attending specialised foot care units in tertiary hospitals experienced short-term CN-associated complications, and the risk was 3 times higher in those with a history of diabetic nephropathy.

Reduction of pharmaceutical expenditure by a drug appropriateness intervention in polymedicated elderly subjects in Catalonia (Spain)

OBJECTIVE

To assess the monetary savings resulting from a pharmacist intervention on the appropriateness of prescribed drugs in community-dwelling polymedicated (≥8 drugs) elderly people (≥70 years).

METHOD

An evaluation of pharmaceutical expenditure reduction was performed within a randomised, multicentre clinical trial. The study intervention consisted of a pharmacist evaluation of all drugs prescribed to each patient using the "Good Palliative-Geriatric Practice" algorithm and the "Screening Tool of Older Persons Prescriptions/Screening Tool to Alert doctors to Right Treatment" criteria (STOPP/START). The control group followed the routine standard of care. A time horizon of one year was considered and cost elements included human resources and drug expenditure.

RESULTS

490 patients (245 in each group) were analysed. Both groups experienced a decrease in drug expenditure 12 months after the study started, but this decrease was significantly higher in the intervention group than in the control group (-14.3% vs.-7.7%; p=0.041). Total annual drug expenditure decreased 233.75 €/patient (95% confidence interval [95%CI]: 169.83-297.67) in the intervention group and 169.40 €/patient (95%CI: 103.37-235.43) in the control group over a one-year period, indicating that 64.30 € would be the drug expenditure savings per patient a year attributable to the study intervention. The estimated return per Euro invested in the programme would be 2.38 € per patient a year on average.

CONCLUSIONS

The study intervention is a cost-effective alternative to standard care that could generate a positive return of investment.

Avoidable hospitalizations due to adverse drug reactions in an acute geriatric unit. Analysis of 3,292 patients

OBJECTIVE

To determine prevalence of admissions due to an adverse drug reaction (ADR) and determine whether or not admission was avoidable, and what drugs and risk factors were implicated.

DESIGN

Cross-sectional observational study.

STUDY SAMPLE

All patients hospitalized in an acute geriatric unit during the period January 2001 to December 2010 were studied.

MEASUREMENT

To determine whether admissions were due toADR, we used the World Health Organization-Uppsala Monitoring Centre criteria and the Naranjo scale. Beers criteria were used to detect potentially inappropriate medication.

RESULTS

A total of 3,292 patients (mean age 84.7 years, 60.1% women) were studied. Of these, 197 (6%) were admissions for ADR and nearly three quarters (76.4%, 152 cases) were considered avoidable admissions. The 5 most frequent drugs associated with admissions for ADR were digoxin, nonsteroidal anti-inflammatory drugs, benzodiazepines, diuretics and antibiotics. Independent risk factors for admissions for ADR were being female (OR 1.84; 95% CI 1.30-2.61), inappropriate medication according to Beers criteria (OR 4.20; 95% CI 2.90-6.03), polypharmacy (>5 drugs) (OR 1.50; 95% CI 1.04-2.13), glomerular filtration rate<30mL/min (OR 3; 95% CI 2.12-4.23) and sedative use (OR 1.40; 95% CI 1-1.91).

CONCLUSION

ADR were responsible for 6% of admissions to an acute geriatric unit, and over 75% of these admissions were considered avoidable. Associated risk factors were being female, inappropriate medication, polypharmacy, renal insufficiency and sedative use.

Risk Factors for Community-Acquired Pneumonia in Adults: A Systematic Review of Observational Studies

We performed a systematic review of the literature to establish conclusive evidence of risk factors for community-acquired pneumonia (CAP). Observational studies (cross-sectional, case-control, and cohort studies) the primary outcome of which was to assess risk factors for CAP in both hospitalized and ambulatory adult patients with radiologically confirmed pneumonia were selected. The Newcastle-Ottawa Scale specific for cohort and case-control designs was used for quality assessment. Twenty-nine studies (20 case-control, 8 cohort, and 1 cross-sectional) were selected, with 44.8% of them focused on elderly subjects ≥65 years of age and 34.5% on mixed populations (participants' age >14 years). The median quality score was 7.44 (range 5-9). Age, smoking, environmental exposures, malnutrition, previous CAP, chronic bronchitis/chronic obstructive pulmonary disease, asthma, functional impairment, poor dental health, immunosuppressive therapy, oral steroids, and treatment with gastric acid-suppressive drugs were definitive risk factors for CAP. Some of these factors are modifiable. Regarding other factors (e.g., gender, overweight, alcohol use, recent respiratory tract infections, pneumococcal and influenza vaccination, inhalation therapy, swallowing disorders, renal and liver dysfunction, diabetes, and cancer) no definitive conclusion could be established. Prompt assessment and correction of modifiable risk factors could reduce morbidity and mortality among adult CAP patients, particularly among the elderly.

Effectiveness of an intervention to prevent frailty in pre-frail community-dwelling older people consulting in primary care: a randomised controlled trial

Background

evidence on the effectiveness of interventions to prevent frailty is scarce.

Objective

to assess the effect of an intervention in preventing frailty progression in pre-frail older people.

Study design

a randomised, open label, controlled trial with two parallel arms.

Population

community-dwelling pre-frail older people (≥70 years) consulting in primary care.

Intervention

nutritional assessment (and derivation to a Nutritional Unit for usual care in the event of nutritional risk) and a physical activity programme including aerobic exercise and a set of mixed strengthening, balance and coordination exercises.

Control group

patients receiving the usual care.

Main outcome measure

prevalence of frailty (Fried criteria) at 12 months.

Secondary outcomes measures

functional capacity (Barthel index), falls and nutritional status (Short-Form Mini Nutritional Assessment) on follow-up at 12 months.

Results

one hundred and seventy-two participants were recruited and randomised (mean age: 78.3 years; mean number of Fried criteria: 1.45). Thirty-nine participants (22.6%) were dropped out during the study. At follow-up, 4.9% of the intervention group and 15.3% of the control group had evolved to frailty, for a crude odds ratio (OR) of 0.29 (95% confidence interval [CI]: 0.08-1.08; P = 0.052) and an adjusted (by age, gender and number of co-morbidities) OR of 0.19 (95% CI: 0.04-0.95; P = 0.044). Intervention group showed a higher outdoors walking hour per day (0.97 versus 0.73; P = 0.019) but no difference was observed in muscle strength, gait speed or other functional indicators.

Conclusion

an intervention focused on physical exercise and maintaining good nutritional status may be effective in preventing frailty in community-dwelling pre-frail older individuals.

Randomized controlled trial of an intervention to improve drug appropriateness in community-dwelling polymedicated elderly people

BACKGROUND

Polypharmacy is frequent in the elderly population and is associated with potentially drug inappropriateness and drug-related problems.

OBJECTIVES

To assess the effectiveness and safety of a medication evaluation programme for community-dwelling polymedicated elderly people.

DESIGN

Randomized, open-label, multicentre, parallel-arm clinical trial with 1-year follow-up.

SETTING

Primary care centres.

PARTICIPANTS

Polymedicated (≥8 drugs) elderly people (≥70 years).

STUDY INTERVENTION

Pharmacist review of all medication according to the Good Palliative-Geriatric Practice algorithm and the Screening Tool of Older Person's Prescriptions-Screening Tool to Alert Doctors to the Right Treatment criteria and recommendations to the patient's physician.

CONTROL INTERVENTION

Routine clinical practice.

MEASUREMENTS

Recommendations and changes implemented, number of prescribed drugs, restarted drugs, primary care and emergency department consultations, hospitalizations and death.

RESULTS

About 503 (252 intervention and 251 control) patients were recruited and 2709 drugs were evaluated. About 26.5% of prescriptions were rated as potentially inappropriate and 21.5% were changed (9.1% discontinuation, 6.9% dose adjustment, 3.2% substitution and 2.2% new prescription). About 2.62 recommendations per patient were made and at least one recommendation was made for 95.6% of patients. The mean number of prescriptions per patient was significantly lower in the intervention group at 3- and 6-month follow-up. Discontinuations, dose adjustments and substitutions were significantly higher than in the control group at 3, 6 and 12 months. No differences were observed in the number of emergency visits, hospitalizations and deaths.

CONCLUSION

The study intervention was safe, reduced potentially inappropriate medication, but did not reduce emergency visits and hospitalizations in polymedicated elderly people.

Serum levels of immunoglobulins and severity of community-acquired pneumonia

Instruction

There is evidence of a relationship between severity of infection and inflammatory response of the immune system. The objective is to assess serum levels of immunoglobulins and to establish its relationship with severity of community-acquired pneumonia (CAP) and clinical outcome.

Methods

This was an observational and cross-sectional study in which 3 groups of patients diagnosed with CAP were compared: patients treated in the outpatient setting (n=54), patients requiring in-patient care (hospital ward) (n=173), and patients requiring admission to the intensive care unit (ICU) (n=191).

Results

Serum total IgG (and IgG subclasses IgG1, IgG2, IgG3, IgG4), IgA and IgM were measured at the first clinical visit. Normal cutpoints were defined as the lowest value obtained in controls (≤680, ≤323, ≤154, ≤10, ≤5, ≤30 and ≤50 mg/dL for total IgG, IgG1, IgG2, IgG3, IgG4, IgM and IgA, respectively). Serum immunoglobulin levels decreased in relation to severity of CAP. Low serum levels of total IgG, IgG1 and IgG2 showed a relationship with ICU admission. Low serum level of total IgG was independently associated with ICU admission (OR=2.45, 95% CI 1.4 to 4.2, p=0.002), adjusted by the CURB-65 severity score and comorbidities (chronic respiratory and heart diseases). Low levels of total IgG, IgG1 and IgG2 were significantly associated with 30-day mortality.

Conclusions

Patients with severe CAP admitted to the ICU showed lower levels of immunoglobulins than non-ICU patients and this increased mortality.

Oral Drugs Related with Muscle Wasting and Sarcopenia. A Review

Sarcopenia is a geriatric syndrome characterized by progressive and generalized loss of skeletal muscle mass and function. Reported prevalence of this geriatric syndrome, differs depending on the definition, the population and the method used to identify sarcopenia. The causes of sarcopenia are multifactorial, and can include genetic influence, immobility or disuse, endocrine factors, inflammation and nutritional deficiencies. These disorders involve an imbalance between anabolic and catabolic pathways that rules muscle mass. Many drugs taken regularly for common conditions may interact with some mechanisms that can alter the balance between protein synthesis and degradation. This may lead to a harmful or a beneficial effect on muscle mass and strength. Widely prescribed drugs could play an important role during the time of onset and development of sarcopenia. In this paper, we reviewed the current understanding of how can drugs contribute positively or negatively on sarcopenia and muscle wasting. We decided to focus this review on oral common drugs, which are usually prescribed in older adults, leaving aside other drugs as hormone therapy.

Clinical and Functional Characterization of Pre-frailty among Elderly Patients Consulting Primary Care Centres

BACKGROUND

Characterization of the main features of pre-frailty may contribute to better understanding the mechanisms involved in the development of frailty.

OBJECTIVE

To characterize the pre-frail population consulting in primary care centres in Mataró (Catalonia, Spain), to describe the Fried's frailty criteria for this population and to identify the main associated factors.

DESIGN

Cross-sectional study.

SETTING

Three primary care centres in Catalonia.

PARTICIPANTS

Pre-frail subjects recruited from among persons aged 70 years and older consulting primary care centres and screened for frailty according to Fried's criteria.

MEASUREMENTS

Clinical, nutritional and functional data.

RESULTS

Frailty prevalence of 31.0% and pre-frailty prevalence of 49.0% were observed. Comorbidity was not especially frequent among elderly individuals classified as pre-frail (except for diabetes with 35.8% prevalence). Functional status and nutritional status were both reasonably satisfactory in pre-frail subjects with mean Barthel score of 98 points and 91% classified as well nourished. Among pre-frail subjects, 35% were obese (body mass index>30); 75% reported pain; 12% had an accidental fall in the previous three months; and the mean number of medications ingested was 6.2. Weakness was the most prevalent frailty criterion (70%), followed by slowness (30%). Weakness was associated with age in men and with pain in women. Poor physical activity was associated with pain.

CONCLUSIONS

Pre-frailty is very common among elderly subjects consulting primary care centres. Weakness, slowness, diabetes, pain and polypharmacy should alert healthcare professionals to the onset of a frailty process.

Sleeve gastrectomy effects on hunger, satiation, and gastrointestinal hormone and motility responses after a liquid meal test

BACKGROUND

The relation between hunger, satiation, and integrated gastrointestinal motility and hormonal responses in morbidly obese patients after sleeve gastrectomy has not been determined.

OBJECTIVE

The objective was to assess the effects of sleeve gastrectomy on hunger, satiation, gastric and gallbladder motility, and gastrointestinal hormone response after a liquid meal test.

DESIGN

Three groups were studied: morbidly obese patients (n = 16), morbidly obese patients who had had sleeve gastrectomy (n = 8), and nonobese patients (n = 16). The participants fasted for 10 h and then consumed a 200-mL liquid meal (400 kcal + 1.5 g paracetamol). Fasting and postprandial hunger, satiation, hormone concentrations, and gastric and gallbladder emptying were measured several times over 4 h.

RESULTS

No differences were observed in hunger and satiation curves between morbidly obese and nonobese groups; however, sleeve gastrectomy patients were less hungry and more satiated than the other groups. Antrum area during fasting in morbidly obese patients was statistically significant larger than in the nonobese and sleeve gastrectomy groups. Gastric emptying was accelerated in the sleeve gastrectomy group compared with the other 2 groups (which had very similar results). Gallbladder emptying was similar in the 3 groups. Sleeve gastrectomy patients showed the lowest ghrelin concentrations and higher early postprandial cholecystokinin and glucagon-like peptide 1 peaks than did the other participants. This group also showed an improved insulin resistance pattern compared with morbidly obese patients.

CONCLUSIONS

Sleeve gastrectomy seems to be associated with profound changes in gastrointestinal physiology that contribute to reducing hunger and increasing sensations of satiation. These changes include accelerated gastric emptying, enhanced postprandial cholecystokinin and glucagon-like peptide 1 concentrations, and reduced ghrelin release, which together may help patients lose weight and improve their glucose metabolism after surgery. This trial was registered at clinicaltrials.gov as NCT02414893.

Evaluation of CONUT for Clinical Malnutrition Detection and Short-Term Prognostic Assessment in Hospitalized Elderly People

OBJECTIVES

To assess agreement between the CONUT and Mini Nutritional Assessment (MNA) instruments in detecting malnutrition in hospitalized elderly patients and to determine their prognostic value compared to that of serum albumin alone in relation to in-hospital and 1-month and 6-month post-discharge mortality rates.

DESIGN

Prospective observational study.

SETTING

A Catalan regional hospital.

PARTICIPANTS

2155 patients admitted to an acute geriatric unit were assessed using MNA and CONUT and were followed up for 6 months after discharge.

MEASUREMENTS

On admission, data were collected on age, sex, referral, geriatric syndromes, cognitive status, functional status and nutritional status according to MNA (as the gold standard). Plasma albumin, total cholesterol and lymphocyte levels were recorded to implement CONUT. Mortality was recorded until 6 months after discharge.

RESULTS

Sample characteristics: 61.3% females, mean age 84.9 years, mean Charlson index 2.2. CONUT sensitivity and specificity for malnutrition were 43% and 71.6%, respectively, with positive and negative predictive values of 88.9% and 19.2%. MNA, CONUT and albumin alone were good predictors of mortality but showed similar sensitivity and specificity results.

CONCLUSION

CONUT agreement with MNA in nutritional risk assessments for elderly people is poor. Although CONUT is a good predictor of short-and medium-term mortality, it adds little to information provided by albumin alone.

Relationship between Plasma Ghrelin Levels and Sarcopenia in Elderly Subjects: A Cross-Sectional Study

OBJECTIVE

The aim of this study was to investigate the relationship between plasma ghrelin levels and sarcopenia in elderly people.

DESIGN

Cross-sectional study.

SETTING

Health consortium medical centers in the Maresme region, Barcelona (Spain).

PARTICIPANTS

Two groups of subjects: persons ≥70 years (elderly group) and persons 25-65 years (young adults).

MEASUREMENTS

Sarcopenia, diagnosed according to the EWGSOP definition, fasting and postprandial plasma ghrelin levels, body composition, hand grip, Barthel score, and frailty using Fried criteria.

RESULTS

Fifty-five elderly subjects and 33 young adults were recruited. In both age groups, mean ghrelin levels were significantly higher in women than in men. However, mean ghrelin levels were similar in elderly and young men (716 vs. 752 pg mL-1, P = 0.763) as well as in elderly and young women (859 vs. 995 pg mL-1, P = 0.190). In the elderly group, subjects with sarcopenia showed significantly lower ghrelin levels than those without sarcopenia (650 vs. 899 pg mL-1, P = 0.036), but these differences disappeared when stratifying by gender. Elderly subjects without sarcopenia had the same ghrelin levels as young adults (899.3 vs. 899.6 pg mL-1). In young women, ghrelin levels correlated with fat free mass (rs = 0.58, P = 0.007) and muscular mass (rs = 0.54, P = 0.015) but these correlations were not observed in men nor in elderly women.

CONCLUSION

This cross-sectional study does not allow a definitive conclusion about the relationship between ghrelin levels and sarcopenia. Further large prospective studies are needed to test this hypothesis.

Mortality among methicillin-resistant Staphylococcus aureus carriers in long-term care facilities

INTRODUCTION

Little is known about the natural course of patients with chronic stable illnesses colonized with methicillin-resistant Staphylococcus aureus (MRSA). The aim is to determine the impact of MRSA colonization in mortality among long-term health care facility (LTHCF) residents.

METHOD

A multicenter, prospective, observational study was designed. Residents in 4 LTHCFs were classified according to MRSA carriage status and followed for 12 months. Treatment consisted of 5 days of nasal mupirocin in MRSA carriers.

RESULTS

Ninety-three MRSA-carriers among 413 residents were identified. Thirty-one MRSA-colonized patients died during the study period, 11 of whom from an infectious disease. Independent predictors of their higher mortality rates included heart failure, current neoplasm, MRSA carriage and COPD at 3 months and these same factors plus stroke, Bar-thel index <40, pressure ulcers, and older age at 12 months. MRSA-persistence was 35% and 62.5% at 3 and 12 months, respectively.

CONCLUSIONS

MRSA colonization among frail LTHCFs residents is highly prevalent, and is associated with higher mortality. Despite treatment of MRSA carriers, many remained colonized. Factors that promote persistence of MRSA colonization, and the impact of their modification on mortality rates in these patients, need further investigation.

Professions and Working Conditions Associated With Community-Acquired Pneumonia

INTRODUCTION

Community-acquired pneumonia (CAP) is not considered a professional disease, and the effect of different occupations and working conditions on susceptibility to CAP is unknown. The aim of this study is to determine whether different jobs and certain working conditions are risk factors for CAP.

METHODOLOGY

Over a 1-year period, all radiologically confirmed cases of CAP (n=1,336) and age- and sex-matched controls (n=1,326) were enrolled in a population-based case-control study. A questionnaire on CAP risk factors, including work-related questions, was administered to all participants during an in-person interview.

RESULTS

The bivariate analysis showed that office work is a protective factor against CAP, while building work, contact with dust and sudden changes of temperature in the workplace were risk factors for CAP. The occupational factor disappeared when the multivariate analysis was adjusted for working conditions. Contact with dust (previous month) and sudden changes of temperature (previous 3 months) were risk factors for CAP, irrespective of the number of years spent working in these conditions, suggesting reversibility.

CONCLUSION

Some recent working conditions such as exposure to dust and sudden changes of temperature in the workplace are risk factors for CAP. Both factors are reversible and preventable.

Metabolic and hormonal contributors to survival in the participants of the Mataró Ageing Study at 8 years follow-up

OBJECTIVE

Ageing is a physiological process that may be influenced by genetic factors as well as metabolic and hormonal determinants. The aim was to describe metabolic and hormonal factors related to survival in the cohort of non-institutionalized people aged >70 years old of the Mataró Ageing Study.

DESIGN AND METHODS

313 individuals were included and followed-up during 8 years. Metabolic syndrome (MS) parameters by International Diabetes Federation and ATP-III as well as hormonal factors (TSH, free-T4, growth hormone, IGF-I, ghrelin, cortisol, dehydroepiandrosterone -DHEA-, DHEAs, testosterone, SHBG, estradiol, estrone, cortisol/DHEA and cortisol/DHEAs) were studied and their relationship with survival was assessed.

RESULTS

At 8 year of follow-up, 96 out of 313 subjects (30·7%) died. No association between MS and its components and survival was found. However, when abdominal perimeter was analyzed according to distribution in quartiles and categorized by gender, the lowest and highest quartile showed higher mortality (P = 0·009; waist circumference (WC) between 98-102 cm in men and 95-102 cm in women were associated to lower mortality). In men, IGF-I, estrone, cortisol/DHEA ratio and cortisol/DHEAs ratio were lower in survivors, and in women, growth hormone and ghrelin were higher in survivors and cortisol/DHEAs ratio was lower. When Cox regression was performed for survival analysis of the whole cohort (adjusting by age, gender, tobacco consumption and WC, cortisol (B = 0·036, P = 0·033), estrone (B = 0·014, P = 0·004) and cortisol/DHEA ratio (B = 0·018, P = 0·008) were significantly associated to mortality. Sequential adjustments including additionally in the model Lawton scale, MiniNutritional Assessment and MCE showed significant association to estrone (P = 0·018).

CONCLUSIONS

Waist circumference in a U-shaped relationship, together with hormonal factors (adrenal steroids and somatotropic axis) influenced survival in individuals participating in Mataró Ageing Study.

Prevalence and risk factors for meticillin-resistant Staphylococcus aureus in an acute care hospital and long-term care facilities located in the same geographic area

To determine the prevalence and risk factors (RF) for methicillin-resistant Staphylococcus aureus (MRSA) during stay in 1 acute care hospital (ACH) and 4 long-term care facilities (LTCF). After obtaining the informed consent, nasal and skin ulcer swabs were taken and a survey was conducted to determine RF for MRSA. Six hundred and ninety nine patients were included, 413 LTCF and 286 ACH patients and MRSA prevalence were 22.5% and 7.3% respectively. MRSA was located in the nares, skin ulcers, and in both in 61.4%, 21.1%, and 17.5%. Among MRSA carriers, 81% of the ACH and 66.7% of the LTCF patients were only colonized. The multivariate analysis for the ACH revealed the following factors to be associated with MRSA: referral from an LTCF (OR 4.84), pressure ulcers (OR 4.32), a Barthel score < 60 (OR 2.60), and being male (OR 5.21). For the LTCF: urinary catheterisation (OR 3.53), pressure ulcers (OR 2.44), other skin lesions (OR 2.64), antibiotic treatment in ≤ 6 months, (OR 2.23), previous MRSA colonization (OR 2.15), and a Barthel score <20 (OR 1.28). Molecular typing identified 2 predominant clones Q, P, present in all centres. No relationship was found between clones and antibiotic susceptibility.

IN CONCLUSION

MRSA prevalence is high in all centres but is 3 times greater in LTCF. The risk factors most strongly associated with MRSA were pressure ulcers and a stay in an LTCF. We propose preventive isolation in these cases.

Passive smoking at home is a risk factor for community-acquired pneumonia in older adults: a population-based case-control study

OBJECTIVE

To assess whether passive smoking exposure at home is a risk factor for community-acquired pneumonia (CAP) in adults.

SETTING

A population-based case-control study was designed in a Mediterranean area with 860 000 inhabitants >14 years of age.

PARTICIPANTS

1003 participants who had never smoked were recruited.

PRIMARY AND SECONDARY OUTCOME MEASURES

Risk factors for CAP, including home exposure to passive smoking, were registered. All new cases of CAP in a well-defined population were consecutively recruited during a 12-month period.

METHODS

A population-based case-control study was designed to assess risk factors for CAP, including home exposure to passive smoking. All new cases of CAP in a well-defined population were consecutively recruited during a 12-month period. The subgroup of never smokers was selected for the present analysis.

RESULTS

The study sample included 471 patients with CAP and 532 controls who had never smoked. The annual incidence of CAP was estimated to be 1.14 cases×10(-3) inhabitants in passive smokers and 0.90×10(-3) in non-passive smokers (risk ratio (RR) 1.26; 95% CI 1.02 to 1.55) in the whole sample. In participants ≥65 years of age, this incidence was 2.50×10(-3) in passive smokers and 1.69×10(-3) in non-passive smokers (RR 1.48, 95% CI 1.08 to 2.03). In this last age group, the percentage of passive smokers in cases and controls was 26% and 18.1%, respectively (p=0.039), with a crude OR of 1.59 (95% CI 1.02 to 2.38) and an adjusted (by age and sex) OR of 1.56 (95% CI 1.00 to 2.45).

CONCLUSIONS

Passive smoking at home is a risk factor for CAP in older adults (65 years or more).
