ABSTRACT

INTRODUCTION: Post-stroke fatigue (PSF) has been described as early exhaustion with tiredness that develops during physical or mental activity and generally does not improve with rest. There are inconsistent findings on the relationship between the characteristics of the ischemic brain lesion and PSF. However, some studies suggest that specific neuroanatomical and neuroplastic changes could explain post-stroke fatigue. The aim was to evaluate the severity of PSF in relation to the location and the size of the ischemic lesion in acute stroke patients to establish possible predictors of PSF. PATIENTS AND METHODS: We performed a prospective observational study to establish potential early predictors of long-term PSF, which was assessed using the Fatigue Assessment Scale six months after ischemic stroke. After segmenting brain infarcts on Diffusion-Weighted Imaging (DWI) images, we studied the association with PSF using Voxel-Based Lesion-Symptom Mapping (VLSM). RESULTS: Out of 104 patients, 61 (59 %) reported PSF. Female sex and history of diabetes mellitus were associated with a greater risk of developing PSF. The association of PSF with female sex was confirmed in a replication cohort of 50 patients. The ischemic lesion volume was not associated with PSF, and VBLSM analysis did not identify any specific brain area significantly associated with PSF. CONCLUSIONS: PSF is frequent in stroke patients, especially women, even after six months. The absence of neuroanatomical correlates of PSF suggests that it is a multifactorial process with biological, psychological, and social risk factors that require further study.

ABSTRACT

BACKGROUND AND PURPOSE: CTP allows estimating ischemic core in patients with acute stroke. However, these estimations have limited accuracy compared with MR imaging. We studied the effect of applying WM- and GM-specific thresholds and analyzed the infarct growth from baseline imaging to reperfusion. MATERIALS AND METHODS: This was a single-center cohort of consecutive patients (n = 113) with witnessed strokes due to proximal carotid territory occlusions with baseline CT perfusion, complete reperfusion, and follow-up DWI. We segmented GM and WM, coregistered CTP with DWI, and compared the accuracy of the different predictions for each voxel on DWI through receiver operating characteristic analysis. We assessed the yield of different relative CBF thresholds to predict the final infarct volume and an estimated infarct growth-corrected volume (subtracting the infarct growth from baseline imaging to complete reperfusion) for a single relative CBF threshold and GM- and WM-specific thresholds. RESULTS: The fixed threshold underestimated lesions in GM and overestimated them in WM. Double GM- and WM-specific thresholds of relative CBF were superior to fixed thresholds in predicting infarcted voxels. The closest estimations of the infarct on DWI were based on a relative CBF of 25% for a single threshold, 35% for GM, and 20% for WM, and they decreased when correcting for infarct growth: 20% for a single threshold, 25% for GM, and 15% for WM. The combination of 25% for GM and 15% for WM yielded the best prediction. CONCLUSIONS: GM- and WM-specific thresholds result in different estimations of ischemic core in CTP and increase the global accuracy. More restrictive thresholds better estimate the actual extent of the infarcted tissue.

ABSTRACT

INTRODUCTION: The general objective of this research is to improve the quality of colorectal cancer screening (CRC) by assessing, as an indicator of effectiveness, the ability of colonoscopy to detect more advanced adenomas in the exposed group than in the control group. MATERIAL AND METHODS: The present work is designed as an open-label randomized study on cancer screening, using two groups based on their exposure to the protocol: an exposed to intervention group (EIG, 167), and a control group (CG, 167), without the intervention of the protocol and by 1:1 matching. RESULTS: In 167 patients in the GEI, 449 polyps are visualized and 274 are adenomas (80.58%), of which 100 (36.49%) are advanced adenomas. In the CG (n = 174), there are 321 polyps and 152 adenomas (82.60%). The variables significantly associated by logistic regression to the detection of adenomas are the male sex with an OR of 2.52. The variable time to withdrawal, ≥9 min, is significant at 99% confidence (p = 0.002/OR 34.67) and the fractional dose is significant at 99% (p = 0.009, OR 7.81). CONCLUSION: Based on the observations made, our study suggests that the intervention in collaboration between primary care and hospital care is effective from a preventive point of view and achieves the objective of effectiveness and quality of the PCCR.

ABSTRACT

BACKGROUND AND PURPOSE: According to current guidelines, patients with aneurysmal subarachnoid haemorrhage (aSAH) are mostly managed in intensive care units (ICUs) regardless of baseline severity. We aimed to assess the prognostic and economic implications of initial admission of patients with low-grade aSAH into a stroke unit (SU) compared to initial ICU admission. METHODS: We reviewed prospectively registered data from consecutive aSAH patients with a World Federation of Neurosurgery Societies grade <3, admitted to our Comprehensive Stroke Centre between April 2013 and September 2018. Clinical and radiological baseline traits, in-hospital complications, length of stay (LOS) and poor outcome at 90 days (modified Rankin Scale score > 2) were compared between the ICU and SU groups in the whole population and in a propensity-score-matched cohort. RESULTS: Of 131 patients, 74 (56%) were initially admitted to the ICU and 57 (44%) to the SU. In-hospital complication rates were similar in the ICU and SU groups and included rebleeding (10% vs. 7%; P = 0.757), angiographic vasospasm (61% vs. 60%; P = 0.893), delayed cerebral ischaemia (12% vs. 12%; P = 0.984), pneumonia (6% vs. 4%; P = 0.697) and death (10% vs. 5%; P = 0.512). LOS did not differ between groups (median [interquartile range] 22 [16-30] vs. 19 [14-26] days; P = 0.160). In adjusted multivariate models, the location of initial admission was not associated with long-term poor outcome either in the whole population (odds ratio [OR] 1.16, 95% confidence interval [CI] 0.32-4.19; P = 0.825) or in the matched cohort (OR 0.98, 95% CI 0.24-4.06; P = 0.974). CONCLUSIONS: A dedicated SU, with care from a multidisciplinary team, might be an optimal alternative to ICU for initial admission of patients with low-risk aSAH.

ABSTRACT

Aim To explore the perceptions of main caregivers regarding caring for chronic complex patients in two different regions of Spain. BACKGROUND: Spain is a country with an ageing population and a high number of people with chronic diseases. It is well known that the role of the caregiver is important to ensure quality of life and appropriate care. METHODS: Qualitative design using focus groups. Five focus groups, from two different regions, were conducted with 22 caregivers of people with chronic complex diseases to explore their personal experience, examine the quality of care received by the patient and their family and to develop strategies for the improvement of the quality of health care. The focus groups were audio and video recorded. The transcriptions of the focus group sessions were exported to qualitative software analysis MAXQDA 2018.2. The qualitative content analysis was based on different analytical cycles. RESULTS: In general terms, caregivers would refer to accepting the care of their family members, but they highlight many negative aspects such as tiredness, lack of help and overload of care. They indicated general satisfaction with the health system but indicated that help was insufficient and that strategies to better address the situations of the complex chronic patient should be improved. The main categories observed were: Conclusions. Complex chronic illnesses are increasingly common at present, generating important consequences on the lives of patients and that of their caregivers. The design of any health strategy for facing the dilemma of chronic illnesses, must necessarily include the vision of the caregivers.

ABSTRACT

BACKGROUND: Alopecia areata (AA) is a skin disease that produces hair loss in patches of skin. The underlying mechanism of AA is a loss of immune privilege of hair follicles, which are then attacked by natural killer (NK) cells. A previous genome-wide association study linked single nucleotide polymorphisms of the protein MHC class I chain-related A (MICA) to this disease. MICA is the ligand for the activating receptor NKG2D, expressed mainly by NK cells and CD8+ cytotoxic T cells. As the aforementioned study did not include short tandem repeats (STRs) of MICA, we decided to study these in relation to AA. AIM: To study the association of STRs with AA, alongside that of human leucocyte antigen (HLA) locus B, which is closely linked to MICA. METHODS: DNA amplicon size analysis was carried out, and HLA-B locus genomic typing was performed by PCR-sequence-specific oligonucleotide analysis. RESULTS: We observed an association between AA and both MICA*009 and HLA-B14; associations were also observed between HLA-B alleles and MICA alleles, which have both been previously found to be connected with AA, but never studied together. CONCLUSIONS: We conclude that it is important to study HLA-B and MICA together to avoid the influence of their association in experiments in which they are investigated separately.

ABSTRACT

BACKGROUND AND PURPOSE: Cancer is a frequent finding in ischaemic stroke patients. The frequency of cancer amongst participants in the NAVIGATE ESUS randomized trial and the distribution of outcome events during treatment with aspirin and rivaroxaban were investigated. METHODS: Trial participation required a recent embolic stroke of undetermined source. Patients' history of cancer was recorded at the time of study entry. During a mean follow-up of 11 months, the effects of aspirin and rivaroxaban treatment on recurrent ischaemic stroke, major bleeding and all-cause mortality were compared between patients with cancer and patients without cancer. RESULTS: Amongst 7213 randomized patients, 543 (7.5%) had cancer. Of all patients, 3609 were randomized to rivaroxaban [254 (7.0%) with cancer] and 3604 patients to aspirin [289 (8.0%) with cancer]. The annual rate of recurrent ischaemic stroke was 4.5% in non-cancer patients in the rivaroxaban arm and 4.6% in the aspirin arm [hazard ratio (HR) 0.98, 95% confidence interval (CI) 0.78-1.24]. In cancer patients, the rate of recurrent ischaemic stroke was 7.7% in the rivaroxaban arm and 5.4% in the aspirin arm (HR 1.43, 95% CI 0.71-2.87). Amongst cancer patients, the annual rate of major bleeds was non-significantly higher for rivaroxaban than aspirin (2.9% vs. 1.1%; HR 2.57, 95% CI 0.67-9.96; P for interaction 0.95). All-cause mortality was similar in both groups. CONCLUSIONS: Our exploratory analyses show that patients with embolic stroke of undetermined source and a history of cancer had similar rates of recurrent ischaemic strokes and all-cause mortality during aspirin and rivaroxaban treatments and that aspirin appeared safer than rivaroxaban in cancer patients regarding major bleeds. www.clinicaltrials.gov (NCT02313909).

ABSTRACT

BACKGROUND: Anal intraepithelial neoplasia (AIN) (or low/high grade squamous intraepithelial neoplasia (L/HSIL)) is the precursor of anal of early invasive anal cancer. Different treatment options for local ablation of localized lesions have been reported. The aim of this study was to analyze the clinical efficacy and safety of infrared coagulation for the treatment of anal dysplasia. METHODS: A search of the literature was performed in 2019 using PubMed and Cochrane to identify all eligible trials published reporting data on the treatment of anal dysplasia with infrared coagulation. The percentage of squamous cell carcinoma of the the anus that developed in the follow-up and results on major complications after treatment were the primary outcomes. RESULTS: Twenty-four articles were identified from which 6 were selected with a total of 360 patients included, with a median age of 41.8 years. Three studies were prospective and 3 retrospective, only one was a randomized trial. All articles included males, 4 articles included HIV-positive women and only one article included non HIV infected males. No patient developed major complications after infrared coagulation therapy. Pain was the most common symptom found after the procedure in the different series and mild bleeding that did not require transfusion was the most common complication occurring in 4 to 78% of patients. Median follow-up was between 4.7 and 69 months. No patient developed squamous cell carcinoma after infrared treatment. Recurrent HSIL varied from 10 to 38%. Two studies reported results from follow-up of untreated patients showing that between 72 and 93% of them had persistent HSIL at last follow-up and 4.8% developed squamous cell carcinoma. CONCLUSIONS: Infrared coagulation is a safe and effective method for ablation of high-grade anal dysplasia that could help prevent anal cancer. Continued surveillance is recommended due to the risk of recurrence.

ABSTRACT

BACKGROUND AND PURPOSE: Leukoaraiosis frequently coexists in patients with acute stroke. We studied whether leukoaraiosis could confound the interpretation of CTP findings in patients treated with mechanical thrombectomy. MATERIALS AND METHODS: We analyzed 236 patients with stroke treated with mechanical thrombectomy and studied with CTP, of whom 127 (53.8%) achieved complete reperfusion. Periventricular white matter hyperintensities on MR imaging and hypodensities on NCCT were assessed through the Fazekas score. CTP-predicted nonviable tissue was defined as relative CBF <30%, and final infarct volume was quantified in DWI. We estimated mean MTT, CBV, and CBF in the asymptomatic hemisphere. In patients achieving complete reperfusion, we assessed the accuracy of nonviable tissue to predict final infarct volume using the intraclass correlation coefficient across periventricular hyperintensity/hypodensity Fazekas scores and variable relative CBF cutoffs. RESULTS: MTT was longer (Spearman ρ = 0.279, P < .001) and CBF was lower (ρ = -0.263, P < .001) as the periventricular hyperintensity Fazekas score increased, while CBV was similar across groups (ρ = -0.043, P = .513). In the subgroup of patients achieving complete reperfusion, nonviable tissue-final infarct volume reliability was excellent in patients with periventricular hyperintensity Fazekas score grade 0 (intraclass correlation coefficient, 0.900; 95% CI, 0.805-0.950), fair in patients with periventricular hyperintensity Fazekas scores 1 (intraclass correlation coefficient, 0.569; 95% CI, 0.327-0.741) and 2 (intraclass correlation coefficient, 0.444; 95% CI, 0.165-0.657), and poor in patients with periventricular hyperintensity Fazekas score 3 (intraclass correlation coefficient, 0.310; 95% CI, -0.359-0.769). The most accurate cutoffs were relative CBF <30% for periventricular hyperintensity Fazekas score grades 0 and 1, relative CBF <25% for periventricular hyperintensity Fazekas score 2, and relative CBF <20% for periventricular hyperintensity Fazekas score 3. The reliability analysis according to periventricular hypodensity Fazekas score grades on NCCT was similar to that in follow-up MR imaging. CONCLUSIONS: In patients with stroke, the presence of leukoaraiosis confounds the interpretation of CTP despite proper adjustment of CBF thresholds.

ABSTRACT

Objetivo: Describir la viabilidad, la seguridad y la eficacia de un enfoque multidimensional para fomentar la actividad física precoz después de un ictus isquémico. Materiales y métodos: Estudio de casos y controles que compara los resultados en los pacientes ingresados en la unidad de ictus antes y después de establecer un protocolo de fomento de la actividad física mediante la incorporación de un ejercicio aeróbico usando un cicloergómetro, y la facilitación de información verbal y escrita sobre los beneficios de la actividad física. La medida principal del estudio fue la actividad física realizada a los 3 meses usando el International Physical Activity Questionnaire. Resultados: Incluimos 93 pacientes (60 controles y 33 en el grupo activo). La actividad física previa al ictus era baja. Las 126 sesiones de cicloergómetro se toleraron bien. A los 3 meses del ictus, la actividad física fue mayor (693 vs. 462 MET-min/semana; p=0,039) y el tiempo de sedestación, menor (2.100 vs. 2.520min; p=0,009) en el grupo activo. Conclusiones: A pesar de un conocimiento apropiado de los beneficios del ejercicio sobre la salud, la actividad física es baja después del ictus. Un enfoque multidisciplinar, combinando ejercicio precoz e información individualizada, puede incrementarla


Objective: To describe the feasibility, safety, and efficacy of a multidimensional approach to promote physical activity soon after ischaemic stroke. Materials and methods: Case-control study comparing the outcomes in consecutive patients admitted to a stroke unit before and after implementing a physical activity promotion protocol by performing aerobic exercise using a cycle ergometer, and informing them on the benefits of physical activity. The primary outcome measurement was physical activity at 3 months using the International Physical Activity Questionnaire. Results: A total of 93 patients were included (60 controls and 33 in the active group). Pre-stroke activity was low. A total of 126 cycle ergometer sessions were well tolerated. At 3 months, post-stroke physical activity was greater (693 vs. 462 MET-min/week; P=.039) and sedentary time shorter (2,100 vs. 2,520min; P=.009) in the active group. Conclusions: Despite proper knowledge of the health benefits of exercise, physical activity is low after stroke. A multidisciplinary approach combining early exercise and individualised information on its benefits may increase physical activity after stroke

ABSTRACT

The objective of the study is to determine the importance of the mode of onset as prognostic factor in systemic sclerosis (SSc). Data were collected from the Spanish Scleroderma Registry (RESCLE), a nationwide retrospective multicenter database created in 2006. As first symptom, we included Raynaud's phenomenon (RP), cutaneous sclerosis, arthralgia/arthritis, puffy hands, interstitial lung disease (ILD), pulmonary arterial hypertension (PAH), and digestive hypomotility. A total of 1625 patients were recruited. One thousand three hundred forty-two patients (83%) presented with RP as first symptom and 283 patients (17%) did not. Survival from first symptom in those patients with RP mode of onset was higher at any time than those with onset as non-Raynaud's phenomenon: 97 vs. 90% at 5 years, 93 vs. 82% at 10 years, 83 vs. 62% at 20 years, and 71 vs. 50% at 30 years (p < 0.001). In multivariate analysis, factors related to mortality were older age at onset, male gender, dcSSc subset, ILD, PAH, scleroderma renal crisis (SRC), heart involvement, and the mode of onset with non-Raynaud's phenomenon, especially in the form of puffy hands or pulmonary involvement. The mode of onset should be considered an independent prognostic factor in systemic sclerosis and, in particular, patients who initially present with non-Raynaud's phenomenon may be considered of poor prognosis.

ABSTRACT

Ulcerative colitis (UC) is one of the two major forms of inflammatory bowel disease, the aetiology of which remains unknown. Several studies have demonstrated the genetic basis of disease, identifying more than 130 susceptibility loci. The major histocompatibility complex class I chain-related gene A (MICA) is a useful candidate to be involved in UC pathogenesis, because it could be important in recognizing the integrity of the epithelial cell and its response to stress. The aim of this study was to analyse the relationship between polymorphisms in the transmembrane domain of MICA and susceptibility to develop UC. A total of 340 patients with UC and 636 healthy controls were genotyped for MICA transmembrane polymorphism using a polymerase chain reaction (PCR) combined with fluorescent technology. Different MICA alleles were determined depending on the PCR product size. The allele MICA*A4 was less frequent in patients than in controls (P = 0·003; OR = 0·643), and this protective role is higher when it forms haplotype with B*27 (P = 0·002; OR = 0·294). The haplotype HLA-B*52/MICA*A6 was also associated with UC [P = 0·001; odds ratio (OR) = 2·914]. No other alleles, genotypes or haplotypes were related with UC risk. Moreover, MICA*A5.1 is associated independently with abscesses (P = 0·002; OR = 3·096) and its frequency is lower in patients diagnosed between ages 17 and 40 years (P = 0·007; OR = 0·633), meaning an extreme age on onset. No association with location, extra-intestinal manifestations or need for surgery was found.

ABSTRACT

BACKGROUND AND PURPOSE: The incidence and significance of perfusion abnormalities on brain imaging in patients with lacunar infarct are controversial. We studied the diagnostic yield of CTP and the type of perfusion abnormalities in patients presenting with a lacunar syndrome and in those with MR imaging-confirmed lacunar infarcts. MATERIALS AND METHODS: A cohort of 33 patients with lacunar syndrome underwent whole-brain CTP on admission. Twenty-eight patients had an acute ischemic lesion at follow-up MR imaging; 16 were classified as lacunar infarcts. Two independent readers evaluated NCCT and CTP to compare their diagnostic yield. In patients with DWI-confirmed lacunar infarcts and visible deficits on CTP, the presence of mismatch tissue was measured by using different perfusion thresholds. RESULTS: The symptomatic acute lesion was seen on CTP in 50% of patients presenting with a lacunar syndrome compared with only 17% on NCCT, and in 62% on CTP compared with 19% on NCCT, respectively, in patients with DWI-confirmed lacunar infarcts. CTP was more sensitive in supratentorial than in infratentorial lesions. In the nonblinded analysis, a perfusion deficit was observed in 12/16 patients with DWI-confirmed lacunar infarcts. The proportion of mismatch tissue was similar in patients with lacunar infarcts or nonlacunar strokes (32% versus 36%, P = .734). CONCLUSIONS: Whole-brain CTP is superior to NCCT in identifying small ischemic lesions, including lacunar infarcts, in patients presenting with a lacunar syndrome. Perfusion deficits and mismatch are frequent in lacunar infarcts, but larger studies are warranted to elucidate the clinical significance of these CTP findings.

ABSTRACT

OBJECTIVE: The objective of this paper is to examine if there is an association between low levels of 25-hydroxyvitamin D (25(OH)D) and insulin resistance (IR) in nondiabetic women with systemic lupus erythematosus (SLE) and to evaluate its impact on arterial stiffness. PATIENTS AND METHODS: In this cross-sectional study 25(OH)D, insulin, insulin resistance measured by the homeostatic model assessment (HOMA-IR), homocysteine, fibrinogen, characteristics of SLE, medications and pulse-wave velocity (PWV) were measured in 106 nondiabetic women with SLE and 101 matched controls. RESULTS: Women with SLE tended to have lower 25(OH)D levels (p = 0.078) and a higher frequency of 25(OH)D deficiency (defined as < 10 ng/ml) than controls (p = 0.058). Patients from the lowest quartile of the 25(OH)D range had higher PWV (p = 0.043), fasting glucose (p = 0.035), insulinemia (p ≤ 0.001), HOMA-IR (p = 0.006), C4 (p = 0.012), as well as more frequent IR (p = 0.002) and metabolic syndrome (p = 0.052) than those in the upper quartile, and no differences were found in age, body mass index (BMI), blood pressure, lipid levels and renal function. In women with SLE, 25(OH)D inversely correlated with insulin (p = 0.006), HOMA-IR (p = 0.008) and C4 (p = 0.048) and tended to correlate with fibrinogen (p = 0.060) after adjustment for BMI, age, SLEDAI, prednisone dose, renal function, inflammation markers and seasonal variation, but not with PWV. In controls, 25(OH)D correlated only with homocysteine after the same adjustment, and the correlation with PWV tended to be significant after adjustment for BMI and age (r = -0.190, p = 0.10). CONCLUSION: Low 25(OH)D levels were found to be associated with increased IR in nondiabetic women with SLE independently of BMI. Low 25(OH)D levels, but not IR, could be associated with increased arterial stiffness in these patients.

BACKGROUND: Several studies have reported an association between alcoholic liver cirrhosis (ALC) or other forms of alcoholic liver disease (ALD) and the genetic variant rs738409 (C>G) in adiponutrin/patatin-like phospholipase domain-containing 3 gene (PNPLA3). AIM: To evaluate the influence of this variant on ALC and other forms of ALD. METHODS: We performed a systematic review of previous studies on the relationship between rs738409 of PNPLA3 and ALD and meta-analysis was conducted in a random-effects model. Calculations of the odds ratios (ORs) and their confidence intervals (CIs), tests for heterogeneity and sensitivity analyses were performed. RESULTS: Database search identified 11 previous studies available for inclusion with a total of 3495 patients with ALD (2087 with ALC) and 5038 controls (4007 healthy subjects and 1031 alcoholics without ALD). Patients with ALC compared to controls had a significantly higher prevalence of the G allele when comparing GG vs. CC (OR 4.30, 95% CI 3.25-5.69; P < 0.00001) or GC vs. CC genotypes (GC vs. CC: OR 1.91, 95% CI 1.67-2.17) or under a recessive or dominant model. Similar results were found when comparing separately patients with ALC vs. alcoholics without ALD or healthy subjects. An association of the G allele with ALD emerged when comparing ALD patients vs. alcoholics without ALD and/or healthy subjects although moderate to large heterogeneity was observed. Our data suggested an additive genetic model for this variant in ALD. CONCLUSION: Our meta-analysis shows that the rs738409 variant of PNPLA3 is clearly associated with alcoholic liver cirrhosis.

ABSTRACT

La falta de adherencia al tratamiento farmacológico es un problema relacionado con el proceso de uso de los medicamentos que puede dar lugar si no se soluciona a resultados negativos asociados a la medicación. Es necesaria la aplicación de medidas y estrategias que permitan corregir esta situación. El objetivo del estudio es identificar las estrategias de ayuda al cumplimiento del tratamiento armacológico que sean aplicables en la práctica clínica por los profesionales de la salud para ayudar a los pacientes a conseguir los resultados en salud que se esperan de los medicamentos. Tras esta revisión, se han encontrado siete tipos de estrategias para abordar y mejorar la adherencia al tratamiento y que presentan posibilidades para su aplicación en la práctica clínica son: Estrategias técnicas, educativas, conductuales, tratamiento de observación directa, técnicas de apoyo social, técnicas dirigidas a profesionales y recuerdo de las estrategias


Non-adherence to drug treatment is a problem related to the process of using medicines. If this problem is not solved, it can give room for negative results associated with medication. It is necessary to apply some measures and strategies to correct this fact. The aim of this study is to identify the aid strategies to treatment compliance. These strategies have to be applied by health prof essionals in clinical practice so as to help patients to achieve the health outcomes that are expected from medicines. After this revision, we have found seven types of strategies, which offer possibilities to be applied in clinical practice, to address and improve adherence to treatment. These strategies are: Technical Strategies, educational, behavioral, directly observed treatment, social support techniques, techniques for professionals and remembrance of the strategies

ABSTRACT

Introducción: Algunos autores han señalado más de 200 factores y variables relacionados con el incumplimiento, que se deben tener en cuenta si se pretende modificarlo. Objetivo: Identificar las características sociodemográficas y clínicas asociadas a la adherencia al tratamiento farmacológico en pacientes ambulatorios con riesgo cardiovascular (RCV). Metodología: A los pacientes que cumplieron los criterios de inclusión se les hizo una entrevista inicial, que incluyó la recogida de las características sociodemográficas y clínicas y el test de adherencia. Se tomaron y registraron los valores de colesterol total y presión arterial, y se determinó el RCV del paciente. Si el RCV era moderado o alto, el paciente se incluía en el estudio. Resultados: La adherencia está favorecida por la percepción por parte del paciente del estado de salud como regular, malo o muy malo, por el sexo femenino y por la presencia de algún factor de RCV, como la dislipemia. Conclusiones: Es necesario considerar las diferentes variables que pueden influir en la adherencia y establecer estrategias individualizadas para luchar contra el incumplimiento del tratamiento farmacológico (AU)


Introduction: Some authors have pointed out more than 200 factors and variables related to the breach, to be taken into account if it is to change it. Objective: To identify sociodemographic and clinical characteristics associated with pharmacological treatment adherence in outpatients with cardiovascular risk. Methodology: Patients who met the inclusion criteria were asked an initial interview, which included collection of demographic and clinical characteristics and the adherence test. Were collected and recorded the values of total cholesterol and blood pressure, and determined the patient’s cardiovascular risk. If the cardiovascular risk was moderate or high, the patient was included in the study. Results: Adherence is favored by the patient’s perception of health status as fair, poor or very poor, for the female gender and the presence of any cardiovascular risk factor such as dyslipidemia. Conclusioins: It is therefore necessary to consider the different variables that may infl uence adherence and set individualized strategies for combating non-compliance with pharmacological treatment (AU)

ABSTRACT

El artículo pretende hacer un análisis de las posibilidades terapéuticas que ofrecen los hospitales de día para adolescentes, atendiendo a una dimensión cualitativa inherente a su estructura. En este sentido, veremos cómo se abren grandes posibilidades de trabajo frente a los tratamientos tradicionales, ya sean de tipo cognitivo-conductual, psicodinámico o sistémico. La terapéutica institucional no solo supone la posibilidad de trabajar de manera interdisciplinar e intensiva, sino que también permite vivenciar una experiencia emocional correctora diferenciada de lo que el adolescente repite en su familia y en sus relaciones de objeto interno. Además, si tenemos presente una posible focalización terapéutica institucional articulada con los objetivos terapéuticos individuales y familiares, veremos cómo se amplían todavía más estas posibilidades (AU)


This paper reflects on the therapeutic potential of adolescent day hospitals by focusing on the qualitative features of its particular structure. In a facility of this sort, new opportunities and possibilities of treatment are opened compared to traditional methods such as behavioural, cognitive, psychoanalytical or systemic therapy. Institutional therapeutics. In addition to working in an interdisciplinary and intensive manner, enables the teenager to experience a corrective emotional experience which differs from what he/she repeats in his/her family and internal object relations. A focalized institutional therapeutic intervention, articulated together with individual and family therapeutic objectives, can enhance the therapeutic possibilities of adolescent day hospitals even more (AU)

ABSTRACT

BACKGROUND: Only a minority of alcoholics develop alcoholic liver disease (ALD) and allelic variants within genes encoding glutathione-S-transferases (GST) have been associated with ALD vulnerability with controversial results. AIM: To assess the effects of GST polymorphisms on ALD by means of a genetic association study and meta-analysis. METHODS: We retrieved published studies on the relationship between allelic variants within GST genes and ALD by means of electronic database search. A meta-analysis was conducted in a fixed or random effects model. Calculations of odds ratios (OR) and their confidence intervals (CI), tests for heterogeneity of the results and sensitivity analysis, have been performed. A genetic association study comparing GSTM1, GSTT1 and GSTP1 genotype distribution among 279 alcoholics with or without ALD and 144 controls was also performed. Results Fifteen previous studies were identified analysing the association of ALD with polymorphisms within GST genes. After meta-analysis, we found a significant association between the possession of the GSTM1 null allele and the presence of ALD (OR=1.43; 95% CI: 1.14, 1.78; P=0.002) among alcoholic patients. A significant association was also found for the possession of the GSTP1 Val/Val genotype and the presence of ALD (OR=2.04; 95% CI: 1.09, 3.80; P=0.03). CONCLUSIONS: Our results suggest that, among alcoholics, carriers of GSTM1 null genetic variant or Val/Val genotype of Ile/Val GSTP1 polymorphism have an increased risk to suffer from alcoholic liver disease. The role of glutathione-S-transferase as a potential therapeutic target in alcoholic liver disease is reinforced.
