Role of Inflammatory Cytokines in the Conversion of Mild Cognitive Impairment to Dementia: A Prospective Study.

BACKGROUND: The effect that cytokines can exert on the progression from mild cognitive impairment (MCI) to ongoing dementia is a matter of debate and the results obtained so far are controversial. OBJECTIVE: The aim of the study is to analyze the influence of markers of subclinical inflammation on the progression of MCI to dementia. METHODS: A prospective study involving a cohort of patients ≥ 65 years of age diagnosed with MCI and followed for 3 years was conducted. 105 patients were enrolled, and serum concentrations of several subclinical inflammatory markers were determined. RESULTS: After 3.09 (2 - 3.79) years of follow-up, 47 (44.76%) patients progressed to dementia. Alpha 1-antichymotrypsin (ACT) was found to be significantly higher in patients who progressed to dementia (486.45 ± 169.18 vs. 400.91 ± 163.03; p = 0.012), and observed to significantly increase the risk of developing dementia in patients with mild cognitive impairment (1.004, 1.001-1.007; p = 0.007). IL-10 levels were significantly higher in those who remained stable (6.69 ± 18.1 vs. 32.54 ± 89.6; p = 0.04). Regarding the type of dementia to which our patients progressed, we found that patients who developed mixed dementia had higher IL-4 levels than those who converted to AD (31.54 ± 63.6 vs. 4.43 ± 12.9; p = 0.03). No significant differences were observed between the groups with regard to the ESR and LPa, CRP, IL-1 and TNF-α levels. CONCLUSION: ACT levels have a significant predictive value in the conversion of MCI to dementia. IL-10 levels could be a protective factor. It is necessary to conduct studies with serial determinations of these and other inflammatory markers in order to determine their effect on the progression of MCI to dementia.

Slump in Hospital Admissions for Stroke, a Fact of an Uncertain Nature That Requires Explanation.

(1) Background: The impact of the health crisis caused by coronavirus disease 2019 (COVID-19) has provoked collateral effects in the attention to pathologies with time-dependent treatments such as strokes. We compare the healthcare activity of two stroke units in the same periods of 2019 and 2020, with an emphasis on what happened during the state of alarm (SA). (2) Materials and methods. Hospitals in the region implemented contingency plans to contain the pandemic; in this planning, the stroke units were not limited in their operational capacity. The SA was declared on 15 March and remained in place for 10 weeks. For the analysis, the data were grouped by consecutive calendar weeks. (3) Results. When the SA was declared the number of calls to the emergency telephone went from 1225 to 3908 calls per week (318% increase). However, the activation of the stroke code went from 6.6 to 5.0 (p = 0.04) and the activity in both stroke units decreased. The largest drop in hospitalizations was for transient ischemic attacks (TIAs) with 35.7% less, 28 vs. 18, (p = 0.05). Reperfusion therapies fell by 37.5%; Poisson regression model 0.64; (95% confidence interval (CI), 0.43-0.95). The overall activity of the telestroke suffered a reduction of 28.9%. We also observed an increase in hospital mortality. (4) Conclusion. The excessive duration of the pandemic precludes any hope of resolving this public health crisis in the short or medium term. Further studies should be conducted to better understand the multifactorial nature of this dramatic decline in stroke admissions and its negative impact.

Glycemic variability: prognostic impact on acute ischemic stroke and the impact of corrective treatment for hyperglycemia. The GLIAS-III translational study.

INTRODUCTION: Glycemic variability (GV) represents the amplitude of oscillations in glucose levels over time and is associated with higher mortality in critically ill patients. Our aim is to evaluate the impact of GV on acute ischemic stroke (IS) outcomes in humans and explore the impact of two different insulin administration routes on GV in an animal model. METHODS: This translational study consists of two studies conducted in parallel: The first study is an observational, multicenter, prospective clinical study in which 340 patients with acute IS will be subcutaneously implanted a sensor to continuously monitor blood glucose levels for 96 h. The second study is a basic experimental study using an animal model (rats) with permanent occlusion of the middle cerebral artery and induced hyperglycemia (through an intraperitoneal injection of nicotinamide and streptozotocin). The animal study will include the following 6 groups (10 animals per group): sham; hyperglycemia without IS; IS without hyperglycemia; IS and hyperglycemia without treatment; IS and hyperglycemia and intravenous insulin; and IS and hyperglycemia and subcutaneous insulin. The endpoint for the first study is mortality at 3 months, while the endpoints for the animal model study are GV, functional recovery and biomarkers. DISCUSSION: The GLIAS-III study will be the first translational approach analyzing the prognostic influence of GV, evaluated by the use of subcutaneous glucose monitors, in acute stroke.

Progression of carotid near-occlusion to complete occlusion: related factors and clinical implications.

BACKGROUND: The clinical consequences and factors related to the progression from a carotid near-occlusion (CNO) to a complete occlusion are not well established. Our aim is to describe the rate, predictive factors and clinical implications of the progression to complete carotid occlusion (PCCO) in a population of patients with symptomatic CNO. METHODS: We conducted a multicenter, nationwide, prospective study from January 2010 to May 2016. Patients with angiography-confirmed CNO were included. We collected information on demographic data, clinical manifestations, radiological and hemodynamic findings, and treatment modalities. A 24 month carotid-imaging follow-up of the CNO was performed. RESULTS: 141 patients were included in the study, and carotid-imaging follow-up was performed in 122 patients. PCCO occurred in 40 patients (32.8%), and was more frequent in medically-treated patients (34 out of 61; 55.7%) compared with patients treated with revascularization (6 out of 61; 9.8%) (p<0.001). 7 of the 40 patients with PCCO (17.5%) suffered ipsilateral symptoms. Factors independently related with PCCO in the multivariate analysis were: age ≥75 years (OR 2.93, 95% CI 1.05 to 8.13), revascularization (OR 0.07, 95% CI 0.02 to 0.20), and collateral circulation through the ipsilateral ophthalmic artery (OR 3.25, 95% CI 1.01 to 10.48). CONCLUSIONS: PCCO occurred within 24 months in more than half of the patients under medical treatment. Most episodes of PCCO were not associated with ipsilateral symptoms. Revascularization reduces the risk of PCCO.

Controlling Nutritional Status (CONUT) Score as a Predictor of All-Cause Mortality at 3 Months in Stroke Patients.

Malnutrition is frequently observed in patients after stroke and is associated with poor outcomes. Patients at risk of malnutrition may be identified with several nutrition screening tools, but no nutritional screening tool has been validated for use with stroke patients. The aim of this study was to explore the ability of the Controlling Nutritional Status (CONUT) score to predict 3-month mortality in stroke patients. METHOD: Patients were recruited from consecutive admissions at a hyperacute stroke unit and were screened for risk of malnutrition (light, moderate, or severe) using CONUT scores. At the next visit, 3-month outcomes were obtained. RESULTS: Of the 164 recruited patients, 51.2% were male. Mean patient age was 77.7 (SD = 7.0) years, and 85.8% of patients had an ischemic stroke. There was a significant difference in the survival rate (p < .001) at 3 months between patients with moderate risk for malnourishment compared to the other patients. The multivariate regression Cox model showed that moderate risk of malnourishment, according to the CONUT score, increased the risk for death at 3 months (hazard ratio = 1.086; 95% CI [1.057, 8.305]; p < .039). CONCLUSION: The CONUT score has predictive validity for all-cause mortality in stroke patients after 3 months, both in hospital and after discharge. Further prospective multicenter studies with larger samples are needed to clarify the usefulness of the CONUT score in the prognosis of all-cause mortality in stroke patients.

Critical points in the experience of spouse caregivers of patients who have suffered a stroke. A phenomenological interpretive study.

AIMS: To explore and document the experiences and values of spouse caregivers of stroke survivors. To gain more in-depth knowledge of how the act of caring and the adaption process affects caregiving spouses. MATERIALS AND METHODS: Phenomenological, qualitative study. This study included spouses of stroke survivors who also served as primary caregivers. Individual, semi-structured, in-depth interviews were conducted, transcribed, and analysed using a thematic content analysis as proposed by Giorgi. Data was analysed and managed using Atlas-ti (version 7.0). This study was approved by our institution´s Complejo Hospitalario de Caceres Ethics and Research Committee. RESULTS: Spouse caregivers of stroke survivors undergo a process of disruption in their private lives and relationships, marked by their caregiving duties. The experiences of spouses caring for stroke survivors is condensed into topics and subtopics: "Caregiving and that´s all" summarizes the sense of having no life horizons and also caregiver impossibility of moving away from caring role. Otherwise, "Breaking the couple´s life together" enlightens the further consequences of stroke in couples shared live biography, which needs to be understood and rebuilt. Finally, "Going through the (non) loss alone" alludes to how spouses reinterpret meaning of loss, which is not appreciated by others and that refers to the balance between stroke survival and any acquired global disability. CONCLUSIONS: A comprehensive approach to the couple (family), from a psycho-socio-emotional and relational perspective, is essential for ensuring adequate quality of life for people who suffered a stroke as well as their caregivers. Spouses-caregivers must be considered as individuals living a transition process due to their unexpected disrupting change, which nurses should address through a comprehensive and integrated approach focused on transition care. Care resources must be adapted to the interpretation that the spouses have of their caregiving role and their relationship with the different components of the caregiving process.

Vascular Risk Factors and Lesions of Vascular Nature in Magnetic Resonance as Predictors of Progression to Dementia in Patients with Mild Cognitive Impairment.

BACKGROUND: Evidence of the effect of vascular risk factors and white matter lesions on the progression of mild cognitive impairment (MCI) to dementia is not conclusive. OBJECTIVE: The study aimed to analyze the impact of these factors on MCI progression to dementia from a global perspective. METHODS: Our study included a population of 105 patients with MCI. RESULTS: After a mean follow-up period of 3.09 years (range, 2-3.79), 47 patients (44.76%) progressed to dementia: 32 (30.8%) to mixed dementia, 13 (12.5%) to probable AD, and 2 (1.9%) to vascular dementia. Total cholesterol levels (OR: 1.015 [1.003-1.028]) and LDL cholesterol levels (OR: 1.018 [1.004-1.032]) increased the risk of progression to dementia. Cystatin C was a protective factor against progression to dementia (OR: 0.119 [0.015-0.944], p = 0.044). During the second year of follow-up, the presence of subcortical white matter hyperintensities increased the risk of progression to dementia (OR: 5.854 [1.008- 33.846]). Subcortical and periventricular white matter hyperintensities were also associated with an increased risk of progression to dementia during the second year of follow-up (OR: 3.130 [1.098-8.922] and OR: 3.561 [1.227-10.334], respectively). The same was true for silent infarcts (OR: 4.308 [1.480- 12.500]). CONCLUSION: A high percentage of patients progressed to dementia. Total cholesterol, LDL cholesterol, and white matter hyperintensities were found to be associated with MCI progression to dementia. In contrast, cystatin C was shown to be a protective factor against progression to dementia.

[Nutritional status and the relationship regarding functional status after stroke]. / Valoración nutricional y su relación con la situación funcional tras sufrir un ictus.

OBJECTIVE: To assess the nutritional status (NS) of patients at three months of suffering a stroke, and to establish the relationship between functional recovery and complications in this period. MATERIAL AND METHODS: A cross-sectional observational study evaluating the NS of patients older than 65 years at three months of having a stroke. The NS was assessed using the Mini Nutritional Assessment (MNA). Sociodemographic and anthropometric data, cardiovascular risk factors, as well as functional status (through the Barthel index and the modified Rankin scale) and the presented complications were collected. RESULTS: One hundred and three patients were included, with a medium age of 75.81 (± 6.73). The MNA score was 23.13 points (± 4.47); 8.2% had malnutrition and 38.1% had risk of malnutrition. There were no differences in the NS between women and men (p = 0.076) neither relation of the NS with age. NS deficiency was associated with poorer function (r = 0.608; p < 0.001), the development of complications (urinary tract infection and fever) (p = 0.044) and dysphagia (p = 0.014). In addition, those patients with better nutritional status had a better quality of life (r = 0.506; p < 0.001). It was also associated with poorer socioeconomic status (p = 0.020) and institutionalization (p = 0.004). CONCLUSIONS: The risk of malnutrition is common in stroke survivors at the short-term. This NS is associated with a worse functional situation and self-perceived quality of life and with a higher rate of complications. Early detection of the risk of malnutrition is essential in patients who have suffered a stroke.

Valoración nutricional y su relación con la situación funcional tras sufrir un ictus / Nutritional status and the relationship regarding functional status after stroke

Objetivo: valorar el estado nutricional (EN) del paciente a los tres meses de sufrir un ictus y establecer la relación del EN con la recuperación funcional y las complicaciones en este periodo. Material y métodos: estudio observacional y transversal que evaluó el EN de pacientes mayores de 65 años a los tres meses de presentar un ictus. El EN se valoró mediante el Mini Nutritional Assessment (MNA). Se recogieron datos sociodemográficos, antropométricos, factores de riesgo cardiovascular, así como el estado funcional (mediante el índice de Barthel y la escala de Rankin modificada) y las complicaciones presentadas. Resultados: incluimos 103 pacientes, con edad media de 75,81 (± 6,73) años. La puntuación en el MNA fue de 23,13 puntos (± 4,47); el 8,2% presentaba malnutrición y el 38,1%, riesgo de malnutrición. No se observaron diferencias en el EN entre mujeres y hombres (p = 0,076) ni relación del EN con la edad. El estado nutricional deficitario se asoció a peor situación funcional (r = 0,608; p < 0,001), al desarrollo de complicaciones (infección urinaria y fiebre) (p = 0,044) y a la disfagia (p = 0,014). Además, aquellos pacientes con mejor EN presentaban mejor calidad de vida (r = 0,506; p < 0,001). También se relacionó con peor nivel socioeconómico (p = 0,020) y mayor institucionalización en centros sociosanitarios (p = 0,004). Conclusiones: el riesgo de desnutrición a corto plazo es frecuente en los supervivientes a un ictus. Este EN se asocia con una peor situación funcional y calidad de vida autopercibida y mayor tasa de complicaciones. Es fundamental detectar precozmente el riesgo de desnutrición en pacientes que han sufrido un ictus (AU)

Early risk of recurrent stroke in patients with symptomatic carotid near-occlusion: Results from CAOS, a multicenter registry study.

Background The risk of recurrent stroke among patients with symptomatic carotid near-occlusion is not well established, and management of the condition remains controversial. Symptomatic carotid near-occlusion with full collapse has been identified as a strong predictor of early recurrence. We aimed to analyze the 90-day risk of recurrent ipsilateral ischemic stroke in medically treated patients with symptomatic carotid near-occlusion. Methods We performed a multicenter, nationwide, prospective study from January 2010 to May 2016. Patients with angiography-confirmed symptomatic carotid near-occlusion were included. The primary endpoint was ipsilateral ischemic stroke or transient ischemic attack (TIA) within 90 days after the presenting event. For this analysis, patients who underwent revascularization within 90 days after stroke were excluded. Results The study population comprised 141 patients from 17 Spanish centers; 83 patients were treated medically. Primary endpoint occurred in eight patients, resulting in a cumulative rate of 10.6% (95% CI, 3.7-17.5). Previous history of stroke or transient ischemic attack was identified as an independent predictor for recurrence in the multivariate Cox regression analysis (HR, 4.37 [95% CI, 1.05-18.18]; p = 0.043), while the presence of full collapse was not associated with an increased risk (HR, 0.81 [95% CI, 0.17-3.92]; p = 0.793). The risk of recurrence was also not affected by the presence of significant stenosis or occlusion of the contralateral carotid artery, or by the collateral circulation. Conclusions Patients with symptomatic carotid near-occlusion seem to have an increased risk of early ipsilateral recurrent stroke. Our results contrast with the low risk of symptomatic carotid near-occlusion reported to date. Full collapse did not increase the risk of recurrent stroke in our study.

Functional Status and Disability in Patients After Acute Stroke: A Longitudinal Study.

BACKGROUND: Stroke is a major public health problem. OBJECTIVE: To use the Barthel Index to evaluate basic activities of daily living in stroke survivors and detect any predictors of functional outcome at 6 months after stroke. METHODS: In an observational longitudinal study, data were gathered on consecutive patients admitted to the comprehensive stroke unit at Hospital San Pedro de Alcantara, Cáceres, Spain. Sociodemographic and clinical data were obtained prospectively at hospital admission and during follow-up 6 months later. Information on type of stroke, score on the Barthel Index, findings from the neurological evaluation, and other relevant data were collected. RESULTS: Of 236 patients admitted, 175 participated in the study. Mean age was 69.60 (SD, 12.52) years, 64.6% were men, and mortality was 12.8%. Six months after experiencing a stroke, 84.8% of patients had returned to their own homes, 8.0% were institutionalized, and the others were residing at a family member's home. Scores on the Barthel Index 6 months after stroke correlated with baseline scores on the National Institute of Health Stroke Scale (r = -0.424; P < .001) and with depressive mood 6 months after stroke (r = -0.318; P < .001). Age was negatively associated with Barthel Index scores at the time of hospital discharge and 6 months after stroke. CONCLUSIONS: Functional status 6 months after stroke was influenced by age, sex, stroke severity, type of stroke, baseline status, mood, and social risk. Comorbid conditions, socioeconomic level, and area of residence did not affect patients' functional status.

Autoimmune post-herpes simplex encephalitis of adults and teenagers.

OBJECTIVE: To report 14 patients with immune-mediated relapsing symptoms post-herpes simplex encephalitis (HSE) and to compare the clinical and immunologic features of the teenage and adult group with those of young children. METHODS: Prospective observational study of patients diagnosed between June 2013 and February 2015. Immunologic techniques have been reported previously. RESULTS: Among the teenage and adult group (8 patients, median age 40 years, range 13-69; 5 male), 3 had an acute symptom presentation suggesting a viral relapse, and 5 a presentation contiguous with HSE suggesting a recrudescence of previous deficits. Seven patients developed severe psychiatric/behavioral symptoms disrupting all social interactions, and one refractory status epilepticus. Blepharospasm occurred in one patient. Five patients had CSF antibodies against NMDA receptor (NMDAR) and 3 against unknown neuronal cell surface proteins. In 5/6 patients, the brain MRI showed new areas of contrast enhancement that decreased after immunotherapy and clinical improvement. Immunotherapy was useful in 7/7 patients, sometimes with impressive recoveries, returning to their baseline HSE residual deficits. Compared with the 6 younger children (median age 13 months, range 6-20, all with NMDAR antibodies), the teenagers and adults were less likely to develop choreoathetosis (0/8 vs 6/6, p < 0.01) and decreased level of consciousness (2/8 vs 6/6, p < 0.01) and had longer delays in diagnosis and treatment (interval relapse/antibody testing 85 days, range 17-296, vs 4 days, range 0-33, p = 0.037). CONCLUSION: In teenagers and adults, the immune-mediated relapsing syndrome post-HSE is different from that known in young children as choreoathetosis post-HSE and is underrecognized. Prompt diagnosis is important because immunotherapy can be highly effective.

Determinants of Quality of Life in Stroke Survivors After 6 Months, from a Comprehensive Stroke Unit: A Longitudinal Study.

BACKGROUND: In the social model of stroke, health-related quality of life (HRQoL) is the result of interplay among stroke severity, social support, and health-promoting behaviors. Our objective was to identify determinants of HRQoL in stroke survivors. METHODS: Ischemic stroke patients were evaluated at 6 months with the Short Form 12 Health Survey, including physical component survey (PCS) and mental health component survey (MCS) summary scores. Multivariate stepwise regression analyses determined independent predictors of scores. Models included age, gender, socioeconomic class, education, residential environment, social support, previous comorbidity (Charlson Index), previous stroke, side of stroke, National Institutes of Health Stroke Scale (NIHSS) score at admission, Barthel Index (BI) and modified Rankin Scale (mRS) scores at discharge, and length of stay. RESULTS: A total of 131 patients participated (mean age 70.1, SD = 12.5; 62.6% males). In all, 33.6% had a BI score <90 and an mRS score >2 (poor outcome). The mean (SD) PCS score was 39.46 (9.3) and mean (SD) MCS score was 34.86 (10.1). Lower PCS score was associated with female sex (ß = 0.204, p = .009), poor social support (ß = -0.225, p = .003), and poor Charlson Index (ß = -0.162, p = .032) and BI scores (ß = 0.384, p < .0001). Lower MCS score was associated with female sex (ß = 0.162, p = .062) and poor NIHSS (ß = -0.265, p = .019) and BI scores (ß = 0.203, p < .071). CONCLUSION: Stroke severity, disability, gender, social support, and previous stroke have significant impacts on the physical and mental domains of generic HRQoL.

Association of vascular factors and amnestic mild cognitive impairment: a comprehensive approach.

BACKGROUND AND OBJECTIVE: Current evidence shows that numerous classic vascular risk factors (VRF) contribute to mild cognitive impairment (MCI), but the effects of emerging VRFs are less well-known. Using a comprehensive approach, we assessed the frequency and strength of association between MCI and classic VRFs, subclinical markers of atherosclerosis (cystatin C, lipoprotein(a), high-sensitivity C-reactive protein, and intima-media thickness) and white matter hyperintensities (WMH). METHODS: In this case-control study of consecutive MCI patients and cognitively normal controls, subjects underwent clinical and neuropsychological examinations, laboratory analyses, a carotid duplex scan, and a brain magnetic resonance imaging scan. RESULTS: The study included 105 patients with amnestic MCI (aMCI): 24 with single domain amnestic MCI, 81 with multiple domain amnestic MCI, and 76 controls. Compared to controls, patients with aMCI were significantly older and had higher rates of arterial hypertension, atrial fibrillation, and depression. They also had a larger intima-media thickness and higher load of WMHs, both periventricular (WMHpv) and subcortical (WMHsc). In the adjusted analysis, all variables except WMHsc displayed a significant association with aMCI. Body mass index exerted a protective effect. CONCLUSIONS: Our findings suggest a direct association between aMCI and age, hypertension, atrial fibrillation depression, intima-media thickness, and WMHpv. Body mass index has a protective effect on this MCI subtype.

Charlson comorbidity index in ischemic stroke and intracerebral hemorrhage as predictor of mortality and functional outcome after 6 months.

BACKGROUND: The Charlson Comorbidity Index (CCI) is commonly used in outcome and mortality studies. Our aim was to investigate the association between CCI score and the functional outcome and mortality 6 months after ischemic stroke (IS) or intracerebral hemorrhage. METHODS: This was a prospective observational cohort of patients with spontaneous intracerebral hemorrhage and IS admitted to the stroke unit during 18 months. The modified Rankin scale (mRS) score was obtained for subjects 6 months after event. The CCI score was dichotomized (low comorbidity 0 or 1 versus high ≥ 2) for analysis. The mRS score was also dichotomized (good outcome, mRS score 0 or 1 versus poor outcome, mRS score ≥ 2). RESULTS: In all, 175 patients were enrolled in the study. Logistic regression showed that those with a high CCI score (≥ 2) had 37.3% increased odds of having a poor outcome (≥ 2) at 6 months and 68.4% greater odds of death at 6 months. CONCLUSIONS: Comorbid medical conditions independently influence outcome after IS or intracerebral hemorrhage.

[Evaluation of the instrumental activities of daily living following a stroke by means of the Lawton and Brody scale]. / Valoración de las actividades instrumentales de la vida diaria tras un ictus mediante la escala de Lawton y Brody.

INTRODUCTION: The instrumental activities of daily living are activities that are somewhat more complex than basic activities of daily living, and being able to perform them allows a person to be independent within a community. They include housework, tasks involving mobility, managing the home and property; catching the bus; cooking meals and going shopping, among other things. AIMS: To evaluate these activities using the Lawton and Brody scale following an ischaemic stroke or intraparenchymatous haemorrhage and to analyse the factors that have an influence on the functional status at six months. PATIENTS AND METHODS: We conducted a prospective study of patients admitted to the stroke unit between September 2010 and June 2011 diagnosed with ischaemic strokes and spontaneous intraparenchymatous haemorrhages. A series of clinical and demographic variables were collected. In the follow-up visit at six months, the patients were re-evaluated by measuring their score on the Lawton and Brody scale again. RESULTS: The percentages of the Lawton and Brody scale at six months were as follows: 28.9% of patients were highly dependent, 45.4% were moderately dependent and 25.6% were dependent. There were differences according to age, severity and the type of stroke, and also depending on the presence of aphasia or hemiparesis. CONCLUSIONS: Patients who have suffered an ischaemic stroke or haemorrhage present a poorer score in instrumental activities of daily living when age is more advanced, the stroke is more severe and when aphasia or hemiparesis are present.

Valoración de las actividades instrumentales de la vida diaria tras un ictus mediante la escala de Lawton y Brody / Evaluation of the instrumental activities of daily living following a stroke by means of the Lawton and Brody scale

Introducción. Las actividades instrumentales de la vida diaria son actividades más complejas que las actividades básicas de la vida diaria, y su realización permite que una persona pueda ser independiente dentro de una comunidad.
