Relationship between Hydration Status and Muscle Catabolism in the Aged Population: A Cross-Sectional Study. Nutrients 2023; 15:4718. [PMID: 38004111 PMCID: PMC10674909 DOI: 10.3390/nu15224718] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/26/2023] [Revised: 11/02/2023] [Accepted: 11/06/2023] [Indexed: 11/26/2023] Open
Abstract
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.

Abstract
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.

Abstract
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. Eur J Hosp Pharm 2022; 31:ejhpharm-2022-003277. [PMID: 35882532 PMCID: PMC10895179 DOI: 10.1136/ejhpharm-2022-003277] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/17/2022] [Accepted: 07/11/2022] [Indexed: 11/03/2022] Open
Abstract
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. Age Ageing 2022; 51:6637440. [PMID: 35810395 DOI: 10.1093/ageing/afac161] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/23/2022] [Indexed: 11/12/2022] Open
Abstract
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.

Severe loss of mechanical efficiency in COVID-19 patients. J Cachexia Sarcopenia Muscle 2021; 12:1056-1063. [PMID: 34102017 PMCID: PMC8242734 DOI: 10.1002/jcsm.12739] [Citation(s) in RCA: 25] [Impact Index Per Article: 8.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/24/2020] [Revised: 04/30/2021] [Accepted: 05/21/2021] [Indexed: 01/11/2023] Open
Abstract
BACKGROUND There is limited information about the impact of coronavirus disease (COVID-19) on the muscular dysfunction, despite the generalized weakness and fatigue that patients report after overcoming the acute phase of the infection. This study aimed to detect impaired muscle efficiency by evaluating delta efficiency (DE) in patients with COVID-19 compared with subjects with chronic obstructive pulmonary disease (COPD), ischaemic heart disease (IHD), and control group (CG). METHODS A total of 60 participants were assigned to four experimental groups: COVID-19, COPD, IHD, and CG (n = 15 each group). Incremental exercise tests in a cycle ergometer were performed to obtain peak oxygen uptake (VO2 peak). DE was obtained from the end of the first workload to the power output where the respiratory exchange ratio was 1. RESULTS A lower DE was detected in patients with COVID-19 and COPD compared with those in CG (P ≤ 0.033). However, no significant differences were observed among the experimental groups with diseases (P > 0.05). Lower VO2 peak, peak ventilation, peak power output, and total exercise time were observed in the groups with diseases than in the CG (P < 0.05). A higher VO2 , ventilation, and power output were detected in the CG compared with those in the groups with diseases at the first and second ventilatory threshold (P < 0.05). A higher power output was detected in the IHD group compared with those in the COVID-19 and COPD groups (P < 0.05) at the first and second ventilatory thresholds and when the respiratory exchange ratio was 1. A significant correlation (P < 0.001) was found between the VO2 peak and DE and between the peak power output and DE (P < 0.001). CONCLUSIONS Patients with COVID-19 showed marked mechanical inefficiency similar to that observed in COPD and IHD patients. Patients with COVID-19 and COPD showed a significant decrease in power output compared to IHD during pedalling despite having similar response in VO2 at each intensity. Resistance training should be considered during the early phase of rehabilitation.

Abstract
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.

Abstract
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.

Abstract
Background. Chronic poststroke oropharyngeal dysphagia (CPSOD) is associated with impaired oropharyngeal sensory/motor function. We aimed to assess effect of sensory (SES) and motor (NMES) transcutaneous electrical stimulation (TES) on safety of swallow and clinical outcomes in patients with CPSOD in a one-year follow-up randomized controlled trial. Methods. Ninety patients (74.1 ± 11.5 y, modified Rankin score 2.6 ± 1.7) with CPSOD and impaired safety of swallow were randomized to (a) compensatory treatment (CT), (b) CT + SES, and (c) CT + NMES. Patients were treated with up to two cycles (6 months apart) of 15 × 1 hour TES sessions over two weeks and followed up with 4-5 clinical and videofluoroscopic assessments during one year. Key results. Baseline penetration-aspiration scale (PAS) was 4.61 ± 1.75, delayed time to laryngeal vestibule closure (LVC) 396.4 ± 108.7 ms, and impaired efficacy signs 94.25%. Swallowing parameters significantly improved between baseline and 1-year follow-up in SES and NMES groups for prevalence of patients with a safe swallow (P < .001), mean PAS (P < .001), time to LVC (P < .01), and need for thickening agents (P < .001). Patients in the CT presented a less intense improvement of signs of impaired safety of swallow without significant changes in time to LVC. No differences between groups were observed for 1-year mortality (6.1%), respiratory infections (9.6%), nutritional and functional status, QoL, and hospital readmission rates (27.6%). No significant adverse events related to TES were observed. Conclusions and inferences. Transcutaneous electrical stimulation is a safe and effective therapy for older patients with CPSOD. After 1-year follow-up, TES greatly improved the safety of swallow and reduced the need for fluid thickening in these patients.

Abstract
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.

Abstract
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.

Abstract
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.

Abstract
The prevalence of older patients with dementia and oropharyngeal dysphagia (OD) is rising and management is poor. Our aim was to assess the prevalence, risk factors, and long-term nutritional and respiratory complications during follow-up of OD in older demented patients. We designed a prospective longitudinal quasi-experimental study with 255 patients with dementia. OD was assessed with the Volume-Viscosity Swallowing Test and a geriatric evaluation was performed. OD patients received compensatory treatments based on fluid viscosity and texture modified foods and oral hygiene, and were followed up for 18 months after discharge. Mean age was 83.5 ± 8.0 years and Alzheimer’s disease was the main cause of dementia (52.9%). The prevalence of OD was 85.9%. Up to 82.7% patients with OD required fluid thickening and 93.6% texture modification, with poor compliance. OD patients were older (p < 0.007), had worse functionality (p < 0.0001), poorer nutritional status (p = 0.014), and higher severity of dementia (p < 0.001) than those without OD and showed higher rates of respiratory infections (p = 0.011) and mortality (p = 0.0002) after 18 months follow-up. These results show that OD is very prevalent among patients with dementia and is associated with impaired functionality, malnutrition, respiratory infections, and increased mortality. New nutritional strategies should be developed to increase the compliance and therapeutic effects for this growing population of dysphagic patients.

Intracellular Water Content in Lean Mass is Associated with Muscle Strength, Functional Capacity, and Frailty in Community-Dwelling Elderly Individuals. A Cross-Sectional Study. Nutrients 2019; 11:nu11030661. [PMID: 30893821 PMCID: PMC6471552 DOI: 10.3390/nu11030661] [Citation(s) in RCA: 13] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/28/2019] [Revised: 03/06/2019] [Accepted: 03/14/2019] [Indexed: 12/18/2022] Open
Abstract
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 (rs = −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.

Abstract
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.

Short-term foot complications in Charcot neuroarthropathy: A retrospective study in tertiary care centres in Spain. ACTA ACUST UNITED AC 2018; 65:479-485. [PMID: 30108031 DOI: 10.1016/j.endinu.2018.06.004] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/12/2018] [Revised: 06/07/2018] [Accepted: 06/07/2018] [Indexed: 11/18/2022]
Abstract
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.

Impact of TSH during the first trimester of pregnancy on obstetric and foetal complications: Usefulness of 2.5 mIU/L cut-off value. Clin Endocrinol (Oxf) 2018; 88:728-734. [PMID: 29453792 DOI: 10.1111/cen.13575] [Citation(s) in RCA: 17] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/24/2017] [Revised: 02/01/2018] [Accepted: 02/06/2018] [Indexed: 11/29/2022]
Abstract
OBJECTIVE An association of pregnancy outcomes with subclinical hypothyroidism has been reported; however, there still exists a strong controversy regarding whether subclinical hypothyroidism ought to be dealt with or not. The objective of the study was to evaluate the association of foetal-maternal complications with first trimester maternal Thyrotropin (TSH) values. DESIGN A retrospective study in a single tertiary care hospital was performed. PATIENTS A total of 1981 pregnant women were studied during 2012. MEASUREMENTS Thyrotropin (TSH) universal screening was performed between 9 and 12 weeks of gestation. Outcomes included foetal-maternal complications and newborn health parameters. RESULTS Median TSH was 1.72 (0.99-2.61) mIU/L. The incidence of perinatal loss, miscarriage and stillbirth was 7.2%, 5.9% and 1.1%, respectively. Median TSH of women with and without miscarriage was 1.97 (1.29-3.28) vs 1.71 (0.96-2.58) mIU/L (P = .009). Incidence of pre-eclampsia was 3.2%; TSH in these women was 2.10 (1.40-2.74) vs 1.71 (0.98-2.59) mIU/L in those without (P = .027). TSH in women with dystocia in labour was 1.76 (1.00-2.53) vs 1.68 (0.94-2.59) mIU/L in those who gave birth with normal progression (P = .044). Women with TSH 2.5-5.1 mIU/L had a higher risk of perinatal loss [OR 1.589 (1.085-2.329)], miscarriage [OR 1.702 (1.126-2.572)] and premature birth [OR 1.39 (1.013-1.876)], adjusted by mother's age. There was no association with the other outcomes analysed. CONCLUSIONS There is a positive association between maternal TSH in the first trimester of pregnancy and the incidence of perinatal loss and miscarriage. The TSH cut-off value of 2.5 mIU/L identified women with higher adverse pregnancy outcomes.

Abstract
BACKGROUND Oropharyngeal dysphagia (OD) is a prevalent poststroke condition with severe complications and increased mortality. Poststroke OD prevalence varies among studies and there is little evidence of its related risk factors and associated complications. OBJECTIVE to evaluate the prevalence of OD after stroke and the risk factors and associated complications. METHODS We performed a prospective longitudinal study of stroke patients consecutively admitted to a general hospital. OD was diagnosed with the volume-viscosity swallow test (V-VST). Demographic, functional status and topographical and clinical variables of stroke were collected to assess risk factors for OD. We evaluated functional status, mortality, respiratory infections, and readmissions 3 and 12 months after stroke. A multivariate regression analysis determined associated risk factors for OD and for each outcome variable. KEY RESULTS We included 395 stroke patients with a 45.06% prevalence of OD on admission. OD was independently associated with age (OR = 1.05; CI = 1.02-1.08), previous stroke (OR = 2.40; CI = 1.00-5.79), severity using the National Institute of Health Stroke Scale (OR = 3.52; CI = 1.57-7.87) and volume of the lesion (OR = 1.02; CI = 1.01-1.03). OD after stroke was an independent risk factor for prolonged hospital stay (P = .049; β = 0.938) and institutionalization after discharge (OR = 0.47; CI = 0.24-0.92); OD was an independent risk factor for poorer functional capacity (OR = 3.00; CI = 1.58-5.68) and increased mortality (HR = 6.90; CI = 1.57-30.34) 3 months after stroke. CONCLUSIONS & INFERENCES Poststroke OD is prevalent and associated with poor short and long term prognosis. Stroke severity and patient status before stroke were more relevant to OD than lesion location. Systematic screening programs and early OD management could significantly improve poststroke patient outcome.

Abstract
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.

Abstract
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.

Abstract
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.

Abstract
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.

Abstract
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.

Abstract
BACKGROUND AND OBJECTIVE Most studies aimed at getting to know the incidence of severe sepsis have methodological limitations which condition results that are difficult to compare and are inapplicable when it comes to estimating the necessary resources. Our objective is to evaluate the incidence and epidemiological aspects of community-acquired severe sepsis which require intensive care unit admission. PATIENTS AND METHOD Prospective observational population-based study in a population of 180,000 adults over 15 years old and a general hospital with 350 beds and 14 ICU beds. All episodes of community-acquired infection requiring admission to ICU due to severe sepsis were registered over a period of 9 years. The variables analyzed were: age, sex, SAPS II score, length of stay in ICU, type of infection, isolated microorganism, and deaths during their ICU admission. A statistical bivariate analysis and a multiple logistic regression were performed. RESULTS Nine hundred and seventeen episodes with an average age of 65.2 years. The most frequent infectious focus was pulmonary (55.2%). The average SAPS II severity score index was 37.87 and mortality 19.7%. The annual incidence was 51.54 episodes per 100,000 adult inhabitants, meaning 1.97 ICU beds per day. In the multivariate analysis, the SAPS II score and a known aetiology were demonstrated as mortality risk factors. CONCLUSIONS This study brings us some epidemiological data from a population-based perspective which help us to care for patients better in our geographical area. The average annual incidence is 51.5 cases per 100,000 adult inhabitants which means that 2 ICU beds per day to attend this population.

Abstract
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.

Abstract
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.

Abstract
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.

Abstract
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.

Abstract
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.

Abstract
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.

Abstract
UNLABELLED 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.

Abstract
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).

Abstract
Obestatin has been proposed to have anorexigenic and anti-ghrelin actions. The objective was to study obestatin concentrations in relation to handgrip strength, functional capacity and cognitive state in old women. The prospective study included 110 women (age, 76.93 ± 6.32) from the Mataró Ageing Study. Individuals were characterized by anthropometric variables, grip strength, Barthel and assessment of cognitive impairment [Mini Cognoscitive Examination (MCE) Spanish version], depressive status by the Geriatric Depression Scale (GDS) and frailty by the Fried criteria. Obestatin was measured by IRMA. Obestatin showed negative correlation to handgrip at basal time point (r = -0.220, p = 0.023) and at 2-year follow-up (r = -0.344, p = 0.002). Obestatin, divided into quartiles, showed a negative lineal association with handgrip: 11.03 ± 4.88 kg in first, 8.75 ± 4.08 kg in second, 8.11 ± 3.66 kg in third and 7.61 ± 4.08 kg in fourth quartile (p = 0.018). Higher obestatin levels were associated to increased weakness (categorized by handgrip of frailty criteria): 2.24 ± 0.42 ng/ml in weak vs. 1.87 ± 0.57 ng/ml in non-weak (p = 0.01). The decrease of either MCE or Barthel scores at 2-year follow-up was significantly higher in individuals in the fourth quartile of obestatin in comparison with individuals in the first quartile (p = 0.046 and p = 0.019, respectively). No association was found between obestatin and GDS score and neither with frailty as a condition. Obestatin is associated to low muscle strength, and impaired functional and cognitive capacity in old women participating in the Mataró Ageing Study.

Relationship between the use of inhaled steroids for chronic respiratory diseases and early outcomes in community-acquired pneumonia. PLoS One 2013; 8:e73271.

Abstract
BACKGROUND The role of inhaled steroids in patients with chronic respiratory diseases is a matter of debate due to the potential effect on the development and prognosis of community-acquired pneumonia (CAP). We assessed whether treatment with inhaled steroids in patients with chronic bronchitis, COPD or asthma and CAP may affect early outcome of the acute pneumonic episode. METHODS Over 1-year period, all population-based cases of CAP in patients with chronic bronchitis, COPD or asthma were registered. Use of inhaled steroids were registered and patients were followed up to 30 days after diagnosis to assess severity of CAP and clinical course (hospital admission, ICU admission and mortality). RESULTS Of 473 patients who fulfilled the selection criteria, inhaled steroids were regularly used by 109 (23%). In the overall sample, inhaled steroids were associated with a higher risk of hospitalization (OR=1.96, p = 0.002) in the bivariate analysis, but this effect disappeared after adjusting by other severity-related factors (adjusted OR=1.08, p=0.787). This effect on hospitalization also disappeared when considering only patients with asthma (OR=1.38, p=0.542), with COPD alone (OR=4.68, p=0.194), but a protective effect was observed in CB patients (OR=0.15, p=0.027). Inhaled steroids showed no association with ICU admission, days to clinical recovery and mortality in the overall sample and in any disease subgroup. CONCLUSIONS Treatment with inhaled steroids is not a prognostic factor in COPD and asthmatic patients with CAP, but could prevent hospitalization for CAP in patients with clinical criteria of chronic bronchitis.

Biological monitoring of PCDD/Fs and PCBs in the City of Mataró. A population-based cohort study (1995-2012). THE SCIENCE OF THE TOTAL ENVIRONMENT 2013; 461-462:612-617. [PMID: 23764673 DOI: 10.1016/j.scitotenv.2013.04.094] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/03/2012] [Revised: 04/29/2013] [Accepted: 04/29/2013] [Indexed: 06/02/2023]
Abstract
There is great concern about the exposure to PCDD/Fs in areas near solid waste incineration (SWI) plants as, in the past, thermal waste treatment was a major source of PCDD/Fs, affecting negatively the environment and the population living nearby the area of influence. The aim of the present study was to monitor PCDD/Fs and PCBs levels in blood samples in general population living nearby a modern SWI. Up to 7 different campaigns were performed between 1995 and 2012. Overall, 104 exposed subjects (living <1000 m from the incinerator plant) and 97 non-exposed subjects (living >3000 m from the incinerator plant) were randomly selected from the municipal census of the City of Mataró in 1995. In addition, workers of the SWI plant were included in the study. Moreover, in 1999, 100 non-exposed subjects living in the nearby City of Arenys de Mar were added to the project. Overall, this study represents the longest consecutive human biomonitoring study of dioxins, furans and PCBs ever conducted in Spain. Concentrations of PCDD/Fs and PCBs were determined according to age, sex and distance to the SWI exposure in whole blood sample pools. No relevant differences in PCDD/Fs and PCBs levels were observed between SWI exposure groups. It could be noted that since 1999 all groups experienced a slight decrease in the levels of PCDD/Fs and marker PCBs. Moreover, concentrations of PCDD/Fs and marker PCBs were higher in women than in men, and in older age group in comparison to the younger ones.

Abstract
OBJECTIVE Ghrelin and obestatin have apparent opposite orexigenic and anorexigenic effects, although the latter has not been firmly demonstrated in humans. So far, little data have been reported in relation to its potential association with metabolic syndrome (MS). The objective was to study obestatin concentrations in relation to nutritional parameters and eating behaviours in old women. DESIGN, PATIENTS AND MEASUREMENTS Prospective study; a total of 110 women (age: 76.93 ± 6.32) from the Mataró Ageing Study were included. Individuals were characterized by anthropometric variables, lipids, glucose, blood pressure, MS components (Adult Treatment Panel III criteria), anorexia and nutritional status by Mini Nutritional Assessment Short Form (MNA-SF) and re-evaluated at 2-year follow-up. Obestatin was measured by IRMA. RESULTS 58.2% of the subjects had MS; at 2-year follow-up 24.1% had a weight loss >5%, 7.2% >10%, and 26.4% changed their MNA-SF score to risk of malnutrition category. Anorexia was present in 38.4%. Obestatin levels were not related to either change of weight, MNA-SF or anorexia, but a positive correlation was found with the absolute difference between basal and 2-year waist circumference (WC) (r = 0.429; P < 0.001) and relative difference between basal and 2-year WC (r = 0.420; P < 0.001); both remained significant after adjusting for age and body mass index. When obestatin was divided into quartiles, a significant lineal trend was observed in relation to WC (P = 0.049), absolute and relative difference between basal and 2-year WC (both P < 0.001). Obestatin was associated with glucose impairment (69.0% in 4th quartile vs 47.5% in 1st to 3rd, P = 0.047; after adjustment, P = 0.098) and MS (77.8% in 4th vs 51.3% in 1st to 3rd, P = 0.017; after adjustment, P = 0.046, OR 2.90 (1.02-8.25) 4th vs 1st to 3rd). CONCLUSIONS Obestatin is elevated in aged women bearing MS but is otherwise not associated with other nutritional parameters, weight loss or anorexia.

Abstract
BACKGROUND The mechanisms involved in anorexia in frail elderly people remain unclear. The objective of this study was to establish whether fasting and postprandial levels of gastrointestinal peptides, gastrointestinal motility, and hunger are modified by age and frailty. METHODS Three groups of subjects were studied: (a) frail elderly (>70 years) persons, (b) non-frail elderly (>70 years) persons, and (c) healthy adults (aged 25-65 years). After an overnight fast, participants ingested a 400 Kcal liquid meal and appetite, hormonal, and gastrointestinal responses were monitored during early (0-60 min) and late (60-240 min) postprandial periods. KEY RESULTS Frail persons showed poor nutritional status, sarcopenia, and almost absence of hunger during fasting and postprandial periods. Older persons presented higher levels of glucose and insulin during fasting, enhanced postprandial CCK release in early postprandial period and postprandial hyperglycemia and hyperinsulinemia, but similar ghrelin levels than younger adults. Ultrasound scan showed that the fasting antral area was higher and antral compliance lower in old persons. The paracetamol absorption test showed enhanced postprandial gastric emptying in the frail. Non-gallbladder contractors showed no CCK peak in younger and non-frail groups, but the same high CCK peak as contractors in the frail. CONCLUSIONS & INFERENCES Frailty was associated with anorexia, risk of malnutrition, and sarcopenia. Frail persons showed impaired gastric motility (larger antral area at rest, impaired antral compliance, and enhanced postprandial emptying), impaired gallbladder motility, and fasting and/or postprandial alterations in CCK, glucose, and insulin release. Further studies are needed to determine if these factors may contribute to anorexia of aging in frail persons.

Abstract
Since 1997 there is an online National Registry of acromegalic patients in Spain (REA). We aimed to study changes in acromegaly treatment and outcomes over the last four decades in Spain. In REA clinical and biochemical data are collected at diagnosis and updated every one to 2 years. We analyzed the first treatment received and the different treatments administered according to decade of diagnosis of acromegaly: prior to 1980, 1980-1989, 1990-1999 and 2000-2009. Surgical cure rates according to pretreatment with long-acting somatostatin receptor ligands (SRLs) were also analyzed. 1,658 patients were included of which 698 had accurate follow-up data. Treatment of acromegaly changed over time. Surgery was the main treatment option (83.8 %) and medical treatment was widely used (74.7 %) both maintained over decades, while radiation therapy declined (62.8, 61.6, 42.2 and 11.9 % over decades, p < 0.001). First treatment type also changed: surgery was the first line option up until the last decade in which medical treatment was preferred (p < 0.001). Radiotherapy was barely used as first treatment. Treatment combinations changed over time (p < 0.001). The most common treatment combination (surgery plus medical therapy), was received by 24.4, 16.4, 25.3 and 56.5 % of patients over decades. Medical treatment alone was performed in 7.3, 6, 7.2 and 14.7 % over decades. Type of medical treatment also changed, SRLs becoming the first medical treatment modality in the last decades, whereas dopamine agonist use declined (p < 0.001). Surgical cure rates improved over decades (21, 21, 36 and 38 %, p = 0.002) and were not influenced by SRL pre-surgical use. Acromegaly treatment has changed in Spain in the last four decades. Surgery has been the main treatment option for decades; however, medical therapy has replaced surgery as first line in the last decade and radiotherapy rates have clearly declined. SRLs are the most used medical treatment.

Abstract
The aim of this study was to explore whether oropharyngeal dysphagia is a risk factor for community-acquired pneumonia (CAP) in the elderly and to assess the physiology of deglutition of patients with pneumonia. In the case-control study, 36 elderly patients (aged ≥ 70 years) hospitalised with pneumonia were matched by age and sex with two independently living controls. All subjects were given the volume-viscosity swallow test to identify signs of oropharyngeal dysphagia. In the pathophysiological study, all cases and 10 healthy elderly subjects were examined using videofluoroscopy. Prevalence of oropharyngeal dysphagia in the case-control study was 91.7% in cases and 40.3% in controls (p<0.001). Adjusting for functionality and comorbidities, dysphagia showed an independent effect on pneumonia (OR 11.9, 95% CI 3.03-46.9). Among cases in the pathophysiological study, 16.7% showed safe swallow, 30.6% high penetrations, 36.1% severe penetrations and 16.7% silent aspirations during videofluoroscopy, while in the healthy elderly subjects these percentages were 80%, 20%, 0% and 0%, respectively (p<0.001). A delay in closure of the laryngeal vestibule (0.414 ± 0.029 s versus 0.200 ± 0.059 s, p<0.01) was the main mechanism of impaired airway protection. In elderly subjects, oropharyngeal dysphagia is strongly associated with CAP, independently of functionality and comorbidities. Elderly patients with pneumonia presented a severe impairment of swallow and airway protection mechanisms. We recommend universal screening of dysphagia in older persons with pneumonia.

Hormonal determinants and effect of ER22/23EK glucocorticoid receptor gene polymorphism on health status deterioration in the participants of the Mataró Ageing Study. AGE (DORDRECHT, NETHERLANDS) 2012; 34:553-61. [PMID: 21544576 PMCID: PMC3337942 DOI: 10.1007/s11357-011-9255-z] [Citation(s) in RCA: 9] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/27/2010] [Accepted: 04/17/2011] [Indexed: 05/30/2023]
Abstract
The purpose of this study is to assess the potential relationships of circulating IGF-I, adrenal and gonadal steroids, and polymorphism ER22/23EK of the glucocorticoid receptor (GC-R) gene with nutritional, functional and cognitive deterioration in a group of elderly people living independently. This is a population-based prospective study with 313 individuals (160 women and 153 men, 76.7 ± 7 years) who participated. A physical exam, evaluation of functional capacity (Barthel scale), cognitive function (mini-mental state examination-MMSE), geriatric depression scale (GDS), mininutritional assessment (MNA-SF) and cardiometabolic status were performed at basal time point and at 2 years of follow-up. Biological measurements included cortisol, dehydroepiandrosterone (DHEA), DHEA sulphate, testosterone, estradiol, IGF-I and polymorphism ER22/23EK of the GC-R gene. Estradiol was associated with MNA-SF decrease over time (p < 0.01, adjusted for age and gender, beta = -0.17, p = 0.03). Weight loss was related to testosterone in men (8.6 vs 12.1 pg/ml in no losers; p = 0.03), and in women with GDS (13.0% with depression vs 3.3% with no depression; p = 0.05) and MMSE (22.2% with cognitive deterioration vs 4.8% with no cognitive deterioration; p = 0.049). Barthel decrease was associated with testosterone (p = 0.02, after adjusting for age and gender, beta = -0.520, p < 0.001), and SHBG (p < 0.01, adjusted for age and gender, beta = 0.18, p < 0.01). DHEA was associated with deterioration in the MMSE (p = 0.01, after adjusting for age, gender, GDS scale and academic status, beta = -0.26, p = 0.01). Frailty development was related only in men with testosterone levels at the beginning of the study (p = 0.017). ER22/23EK was found in 3% of the subjects and carriers had a lower prevalence of hypertension. Adrenal and gonadal steroids are associated to impairment of the ageing health condition in elderly individuals living independently in Spain. ER22/23EK polymorphism of the GC-R gene has a low prevalence in our population.

Abstract
Purpose Respiratory infection is the most common cause for acute exacerbation of chronic obstructive pulmonary disease (AE-COPD). The aim of this work was to study the etiology of the respiratory infection in order to assess the usefulness of the clinical and analytical parameters used for COPD identification. Patients and methods We included 132 patients over a period of 2 years. The etiology of the respiratory infection was studied by conventional sputum, paired serology tests for atypical bacteria, and viral diagnostic techniques (immunochromatography, immunofluorescence, cell culture, and molecular biology techniques). We grouped the patients into four groups based on the pathogens isolated (bacterial versus. viral, known etiology versus unknown etiology) and compared the groups. Results A pathogen was identified in 48 patients. The pathogen was identified through sputum culture in 34 patients, seroconversion in three patients, and a positive result from viral techniques in 14 patients. No significant differences in identifying etiology were observed in the clinical and analytical parameters within the different groups. The most cost-effective tests were the sputum test and the polymerase chain reaction. Conclusion Based on our experience, clinical and analytical parameters are not useful for the etiological identification of COPD exacerbations. Diagnosing COPD exacerbation is difficult, with the conventional sputum test for bacterial etiology and molecular biology techniques for viral etiology providing the most profitability. Further studies are necessary to identify respiratory syndromes or analytical parameters that can be used to identify the etiology of new AE-COPD cases without the laborious diagnostic techniques.
