[Seroprevalence of Hepatitis B virus (HBV), Hepatitis C virus (HCV) and Human Immunodeficiency Virus (HIV) in a sample of patients diagnosed with Alcohol User Disorder in Albacete (Spain).] / Seroprevalencia del virus de la hepatitis B, del virus de la hepatitis C y del virus de la inmunodeficiencia humana en una muestra de pacientes diagnosticados de trastorno por consumo de alcohol en Albacete.

OBJECTIVE: Studies report a higher prevalence of HCV, HBV and HIV in the population with Alcohol Use Disorder. Our objective is to determine the seroprevalence for hepatitis B and C and the human immunodeficiency virus (HIV) in patients with alcohol use disorder, as well as to determine if there is a correct serological screening of these. METHODS: Retrospective study of 204 patients with Alcohol Use Disorder followed up in the Addictive Behaviors Unit from Albacete. They started treatment from 2013-2014 onwards, the last patient was recruited in December of 2017. RESULTS: Our sample has 160 men (78.4%) and 44 women (21.6%). The median age is 46.2 years. 161 patients (78.9%) had HIV serology and it was negative in all. 146 patients (71.6%) had negative hepatitis B serology and 12 (5.9%) were vaccinated. 36 patients (17.6%) had no hepatitis B serology performed. In 10 patients, hepatitis B serology was positive (4.9%; 95% CI 1.9-7.9%). 159 patients (77.9%) had negative hepatitis C serology, and 37 patients had not performed it (18.1%). 8 patients had positive serology (prevalence of 3.9%; 95% CI 1.2-6.6%). Excluding patients who did not have serology, seroprevalence was 5.9% (95% CI 2.3-9.6%) and 4.8% (95% CI 1.5-8.1%) respectively. Failure to perform serologies was associated with older age and less weekly Standard Drink Units (SDUs) consumption. CONCLUSIONS: The seroprevalence of HBV and HCV in patients with alcohol use disorder is high. It should be ensured that 100% of patients with alcohol use disorder undergo HCV, HIV, HBV serology, reducing the loss of diagnostic opportunities.

OBJETIVO: Estudios relatan mayor prevalencia de VHC, VHB y VIH en población con Trastorno de Consumo de Alcohol. El objetivo de nuestro estudio fue determinar la seroprevalencia para Virus de Hepatitis B (VHB), Virus de Hepatitis C (VHC) y el Virus de la Inmunodeficiencia Humana (VIH) en pacientes con trastorno por consumo de alcohol, así como determinar si existe un correcto cribaje serológico de éstos. METODOS: Estudio retrospectivo de 204 pacientes con trastorno por consumo de alcohol seguidos en la unidad de conductas adictivas de Albacete, que iniciaron tratamiento desde el año 2013-2014 en adelante, el último paciente fue reclutado en diciembre de 2017. RESULTADOS: Nuestra muestra tiene 160 hombres (78,4%) y 44 mujeres (21,6%). La mediana de edad es 46,2 años. 161 pacientes (78,9%) tenían serología de VIH y fue negativa en todos. 146 pacientes (71,6%) tenían serología negativa de hepatitis B y 12 (5,9%) estaban vacunados. 36 pacientes (17,6%) no tenían serología realizada de hepatitis B. En 10 pacientes la serología de hepatitis B fue positiva (4,9%; IC95% 1,9-7,9%). 159 pacientes (77,9%) tenían serología negativa de hepatitis C, y 37 pacientes no la tenían realizada (18,1%). 8 pacientes tenían serología positiva (prevalencia de 3,9%; IC95% 1,2-6,6%). Excluyendo a los pacientes que no tenían serología la seroprevalencia fue de 5,9% (IC95% 2,3-9,6%) y de 4.8% (IC95% de 1,5-8,1%) respectivamente. La no realización de serologías se asoció a mayor edad y un menor consumo de Unidades de Bebida Estándar (UBEs) por semana. CONCLUSIONES: La seroprevalencia de VHB y VHC en pacientes con trastorno por consumo de alcohol es alta. Debería asegurarse que el 100% de pacientes con trastorno de consumo de alcohol, se realicen serologías de VHC, VIH, VHB disminuyendo pérdida de oportunidades diagnósticas.

Common Laboratory Parameters Are Useful for Screening for Alcohol Use Disorder: Designing a Predictive Model Using Machine Learning.

The diagnosis of alcohol use disorder (AUD) remains a difficult challenge, and some patients may not be adequately diagnosed. This study aims to identify an optimum combination of laboratory markers to detect alcohol consumption, using data science. An analytical observational study was conducted with 337 subjects (253 men and 83 women, with a mean age of 44 years (10.61 Standard Deviation (SD)). The first group included 204 participants being treated in the Addictive Behaviors Unit (ABU) from Albacete (Spain). They met the diagnostic criteria for AUD specified in the Diagnostic and Statistical Manual of mental disorders fifth edition (DSM-5). The second group included 133 blood donors (people with no risk of AUD), recruited by cross-section. All participants were also divided in two groups according to the WHO classification for risk of alcohol consumption in Spain, that is, males drinking more than 28 standard drink units (SDUs) or women drinking more than 17 SDUs. Medical history and laboratory markers were selected from our hospital's database. A correlation between alterations in laboratory markers and the amount of alcohol consumed was established. We then created three predicted models (with logistic regression, classification tree, and Bayesian network) to detect risk of alcohol consumption by using laboratory markers as predictive features. For the execution of the selection of variables and the creation and validation of predictive models, two tools were used: the scikit-learn library for Python, and the Weka application. The logistic regression model provided a maximum AUD prediction accuracy of 85.07%. Secondly, the classification tree provided a lower accuracy of 79.4%, but easier interpretation. Finally, the Naive Bayes network had an accuracy of 87.46%. The combination of several common biochemical markers and the use of data science can enhance detection of AUD, helping to prevent future medical complications derived from AUD.

METABOLIC SYNDROME AND ITS COMPONENTS IN SPANISH POSTMENOPAUSAL WOMEN.

OBJECTIVES: this study aimed to estimate prevalence of metabolic syndrome and all its components to know the cardiovascular risk and metabolic control of the main risk factors in postmenopausal women aged over 45 years in the province of Cuenca (Castilla-La Mancha, Spain). METHODS: in this cross-sectional study, we randomly selected 716 postmenopausal women from 3,108 women aged over 45. Metabolic syndrome was identified according to the National Cholesterol Education Program Adult Treatment Panel III definition. Cardiovascular risk was calculated by the Systematic Coronary Risk Evaluation ( < 65 years). The American Diabetes Association´s standards of medical care in diabetes were used to estimate metabolic control. The statistical analysis was done with SPPS.19 RESULTS: prevalence of metabolic syndrome was 61.7% (95%CI: 56.9-66.4). Prevalence of each component was: high blood pressure: 95.8% (95%CI: 95.7-95.8), abdominal obesity: 91% (95%CI: 90.9-91.0), low high-density lipoproteins cholesterol (HDLc) levels: 70% (95%CI: 69.8-69.9), high triglyceride levels: 56.9% (95%CI: 56.4- 56.9), high glucose levels: 54.3% (95%CI: 54.2-54.3). Cardiovascular risk was moderate until 65 years, but was high after this age. Metabolic control in postmenopausal women was very good for glucose, bad for systolic blood pressure and worse for lipid levels. Bad blood pressure control was associated with being over 65 years, being hypertensive and taking treatment for diabetes, but it reduced when being physically limited to do moderate exercise and anxiety increased. CONCLUSIONS: prevalence of metabolic syndrome in postmenopausal women in the province of Cuenca is the highest in Spain. High blood pressure and abdominal obesity are the commonest components. Cardiovascular risk was moderate-high in postmenopausal women, but systolic blood pressure and lipid profile were unsatisfactorily controlled. Early intervention is necessary to achieve a better risk profile.

Objetivo: los objetivos de este estudio fueron estimar la prevalencia del síndrome metabólico y cada uno de sus componentes en mujeres menopáusicas mayores de 45 años de la provincia de Cuenca (España), con el fin de conocer su riesgo cardiovascular y el control metabólico de los principales factores de riesgo. Método: estudio observacional, transversal con selección aleatoria de 716 mujeres entre 3.108 menopáusicas mayores de 45 años. El síndrome metabólico se identificó de acuerdo con la definición del NCEP-ATP III. El riesgo cardiovascular se calculó con la tabla SCORE en las menores de 65 años y se utilizaron los estándares de la American Diabetes Association "ADA" para estimar el control metabólico. El análisis estadístico se realizó con el programa SPSS.19. Resultados: la prevalencia del síndrome metabólico fue del 61,7% (IC95% 56,9-66,4). La prevalencia de cada componente fue: hipertensión arterial: 95,8% (IC95% 95,7-95,8), obesidad abdominal: 91% (IC95% 90,9-91,0), niveles bajos de HDLc: 70% (IC95% 69,8-69,9), hipertrigliceridemia: 56,9% (IC95% 56,4-56,9), hiperglucemia: 54,3% (IC95% 54,2-54,3). El riesgo cardiovascular fue moderado hasta los 65 años y alto en la mayoría de las mujeres que superaban esa edad. El control metabólico fue muy bueno para la glucemia, malo para la presión arterial sistólica y peor para los niveles de lípidos. El mal control de la presión sanguínea se asoció a ser mayor de 65 años, hipertensa y recibir terapia antidiabética, mejorando cuando la limitación física para actividades moderadas y la ansiedad aumentaban. Conclusiones: la prevalencia de síndrome metabólico en mujeres postmenopáusicas de la provincia de Cuenca es la más alta de España. La hipertensión y la obesidad abdominal son los componentes más frecuentes. El riesgo cardiovascular es moderado­alto en la postmenopausia; sin embargo, el control de la hipertensión arterial sistólica y del perfil lipídico es insatisfactorio. Es necesaria una intervención precoz para mejorar su perfil de riesgo.

[Subclinical hypothyroidism and cardiovascular risk]. / HIPOTIROIDISMO SUBCLÍNICO Y RIESGO CARDIOVASCULAR.

OBJECTIVE: To assess whether subclinical hypothyroidism can behave as a cardiovascular risk factor or a modifier thereof, identifying epidemiological variables and estimated in a sample of patients diagnosed in the province of Albacete (Spain) cardiovascular risk. METHODOLOGY: Observational, descriptive study was carried out in Albacete during the first half of January 2012 in patients of both genders with subclinical hypothyroidism. The following variables were analyzed: Fasting glucose , total cholesterol , HDL cholesterol, LDL cholesterol , triglycerides , TSH , T4 , weight, height, Body Mass Index , blood pressure, a history of cardiovascular disease , cardiovascular risk factors and estimated cardiovascular risk. RESULTS: 326 patients younger than 65 years at 78% without cardiovascular risk factors in 48.61 %, with female predominance (79.2 %). The prevalence of cardiovascular risk factors was identified: smoking (33.2 %), diabetes mellitus (24.9%), hypertension (23.4 %), lipid abnormalities (28.9%) and atrial fibrillation (4,9%). No association between subclinical hypothyroidism and most lipid profile parameters that determine a pro- atherogenic profile, except with hypertriglyceridemia was found. Likewise, neither association with increased cardiovascular risk was found. DISCUSSION: The profile of patients with subclinical hypothyroidism is a middle-aged woman with no cardiovascular risk factors in half of cases. It has been found relationship between subclinical hypothyroidism and hypertriglyceridemia, but not with the other parameters of lipid profile, other cardiovascular risk factors or with increased risk. However, 25% of diabetics and 22% of non-diabetics are at moderate to high cardiovascular risk.

Objetivos: Valorar si el hipotiroidismo subclínico puede comportarse como un factor de riesgo cardiovascular o un modificador del mismo, identificando variables epidemiológicas y riesgo cardiovascular estimado en una muestra de sujetos diagnosticados en la provincia de Albacete. Método: Estudio observacional, descriptivo y transversal realizado en Albacete durante la primera quincena de enero de 2012 en pacientes de ambos géneros con hipotiroidismo subclínico. Se analizaron las siguientes variables: glucemia basal, colesterol total, colesterol HDL, colesterol LDL, triglicéridos, TSH, T4, peso, talla, I.M.C., tensión arterial, antecedentes de patología cardiovascular, factores de riesgo cardiovascular y riesgo cardiovascular estimado. Resultados: Se obtuvieron 326 pacientes, con predominio femenino (79,2 %), menores de 65 años en el 78% y sin factores de riesgo cardiovascular en el 48,61%. La prevalencia de los factores de riesgo cardiovascular identificados fué: tabaquismo (33,2%), diabetes mellitus (24,9%), hipertensión arterial (23,4%), alteraciones lipídicas (28,9%) y fibrilación auricular (4,9 %). No se encontró asociación entre hipotiroidismo subclínico y la mayoría de los parámetros del perfil lipídico que condicionan un perfil pro-aterogénico, salvo con la hipertrigliceridemia. Asimismo, tampoco se constató asociación con riesgo cardiovascular aumentado. Conclusiones: El perfil del paciente con hipotiroidismo subclínico es una mujer de mediana edad sin factores de riesgo cardiovascular en la mitad de casos. Se ha encontrado relación entre hipotiroidismo subclínico e hipertrigliceridemia, pero no con el resto de parámetros del perfil lipídico, otros factores de riesgo cardiovascular o con aumento de dicho riesgo. Sin embargo, un 25% de diabéticos y un 22% de no diabéticos están en situación de riesgo cardiovascular moderado-alto.
