Association between hormone therapy and short-term cardiovascular events in women with spontaneous coronary artery dissection.

INTRODUCTION AND OBJECTIVES: Changes in sex hormone levels are a known triggering factor for spontaneous coronary artery dissection (SCAD) in women. However, it is unknown whether exposure to exogenous hormone therapy (HT) at the time of SCAD presentation modifies the clinical course of this condition. We investigated the association between HT in female patients presenting with SCAD and short-term clinical outcomes. METHODS: We enrolled consecutive patients presenting with SCAD from the DISCO-IT/SPA (dissezioni spontanee coronariche Italian-Spanish) registry. Women on HT (estrogens, progestagens, or gonadotropins) at the time of presentation were identified, and their clinical characteristics and short-term outcomes were compared with those not receiving active HT. The outcome measure was nonfatal myocardial infarction and/or unplanned percutaneous coronary intervention during the first 28 days after the index catheterization. RESULTS: Of 224 women presenting with SCAD (mean age 52.0±10.0 years), 39 (17.4%) were currently using HT while 185 (82.6%) were not. No significant differences were noted in the baseline demographics, clinical presentation, angiographic features, or initial treatment received between the 2 groups. All patients on systemic HT (n=36, 92%) discontinued it at the time of diagnosis. The composite outcome occurred in 7 (17.9%) patients with prior HT compared with 14 (7.6%) without (P=.039). After multivariable adjustment, HT remained associated with the composite outcome recorded in the first 28 days of follow-up (HR, 3.53; 95%CI, 1.30-9.61; P=.013). CONCLUSIONS: In women with SCAD, exposure to HT at the time of clinical presentation was associated with short-term recurrent cardiovascular events such as nonfatal myocardial infarction and/or unplanned percutaneous revascularization.

Efficiency of screening for human immunodeficiency virus infection in emergency departments: a systematic review and meta-analysis. / Eficiencia del cribado de VIH en urgencias: revisión sistemática y metanálisis.

OBJECTIVES: The rates of undiagnosed and late-diagnosed human immunodeficiency virus (HIV) infection are high. Screening for HIV infection in hospital emergency departments (EDs) could offer a way to increase the number of diagnoses. Our aim was to analyze whether universal hospital ED screening for HIV is efficient. MATERIAL AND METHODS: We followed the guidelines for Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). PubMed, the Cochrane Library, LILACS, Scopus, EMBASE, and the Web of Science were searched using the following terms: "HIV infections/epidemiology," "AIDS serodiagnosis," "emergency service, hospital," "prevalence," and "mass screening/methods." The searches were limited to a 5-year time frame (2016-2020); only publications in English or Spanish were collected. We included studies of universal HIV screening among hospital ED patients and evaluated them using the Quality Assessment Tool for Quantitative Studies. RESULTS: A total of 273 articles were identified. Twelve met the inclusion criteria. The studies analyzed 103 731 patient samples and yielded 652 new HIV diagnoses. A random effects model estimated an overall new-diagnosis prevalence of 0.60% (95% CI, 0.39%-0.84%). The heterogeneity statistic I2 was high, at 90.02% (P .001). Estimates of prevalence based on studies carried out in Europe, the United States, and Africa were, respectively, 0.48% (95% CI, 0.13%-1.03%), 0.54% (95% CI, 0.33%-0.40%), and 5.6% (95% CI, 3.37%-9.2%). The studies received quality ratings of moderate or strong. CONCLUSION: Although the reviewed studies applied various screening strategies to identify new HIV diagnoses, our findings support the conclusion that universal screening is efficient.

OBJETIVO: Existe una elevada tasa de infección oculta y diagnóstico tardío en el virus de la inmunodeficiencia hu mana (VIH). La realización de pruebas diagnósticas de infección por VIH en los servicios de urgencias hospitalarios (SUH) puede representar una oportunidad para aumentar el número de diagnósticos. El objetivo de este trabajo es analizar si el cribado universal para el VIH realizado en los SUH es eficiente. METODO: Se realiza una revisión sistemática y metanálisis siguiendo la normativa PRISMA en la base de datos de Pubmed, Cochrane, LILACS, Scopus, EMBASE y WOS utilizando una combinación de términos MESH: "HIV Infections/ epidemiology", "AIDS Serodiagnosis", "Emergency Service, Hospital", "Prevalence", "Mass screening/methods". Los criterios de la búsqueda se centraron en los últimos 5 años (2016-2020) y en los artículos publicados en inglés y en español. Se incluyeron los estudios de pruebas de cribado universal mediante test de cribado de VIH realizadas en los SUH. Para evaluar la calidad de los artículos se utilizó el cuestionario "Quality assessment tool for quantitative studies". RESULTADOS: Se identificaron un total de 273 artículos de los cuales se analizaron finalmente 12 que cumplían los criterios de inclusión. Los estudios incluidos representan un total de 103.731 muestras analizadas obteniéndose un total de 652 nuevos diagnósticos de VIH. La prevalencia conjunta obtenida a través del modelo de efectos aleatorios fue de 0,60% (IC 95%: 0,39-0,84) y el valor del I2 revela una presencia elevada de heterogeneidad (I2 90,02%; p 0,001). La prevalencia conjunta en los estudios incluidos realizados en Europa, América y África fue de 0,48% (IC 95%: 0,13-1,03), 0,54% (IC 95%: 0,33-0,40) y 5,6% (IC 95%: 3,37-9,2), respectivamente. La evaluación de la calidad de los estudios fue de moderada a fuerte. CONCLUSIONES: Aunque las pruebas del VIH pueden realizarse utilizando diferentes estrategias, nuestros datos avalan que una estrategia de cribado universal es eficiente.

Analysis of a non-synonymous single nucleotide polymorphism of the human diamine oxidase gene (ref. SNP ID: rs1049793) in patients with Crohn's disease.

OBJECTIVE: To analyse the possible influence of a non-synonymous single nucleotide polymorphism (SNP) of the histamine-degrading enzyme diamine oxidase (DAO) on genetic susceptibility to Crohn's disease (CD). MATERIAL AND METHODS: In this prospective, case-control study, 210 unrelated Caucasian consecutive CD patients were recruited at the Inflammatory Bowel Disease Unit of a single tertiary centre (Hospital Clínico San Carlos) in Madrid, Spain. A total of 261 healthy volunteers from the same geographic area were also recruited and matched with patients. Both cases and controls were analysed for the presence of a non-synonymous SNP (rs1049793) of DAO using amplification-restriction procedures of the genotype obtained in a blood sample. RESULTS: No significant differences were found in the distribution of carriers of the non-synonymous SNP of DAO between CD patients and controls (OR 1.2 (95% CI 0.9-1.6; p=0.3)). Nor were any differences found between carriers and non-carriers of the non-synonymous SNP in demographic characteristics, phenotypes, complications or treatment of CD. CONCLUSIONS: The study of a non-synonymous SNP (rs1049793) of DAO does not seem to be of use in assessing susceptibility to CD, either as a marker of disease activity or as a marker of clinical behaviour in patients with the disease.

[Prevalence of lower urinary tract symptoms related with benign prostatic hyperplasia. Study of 1804 men aged 40 or older in Madrid]. / Prevalencia de síntomas del tracto urinario inferior relacionados con la hiperplasia benigna de próstata. Estudio de 1804 hombres de 40 años o más residentes en Madrid durante 1999-2000.

INTRODUCTION: Lower urinary tract symptoms (LUTS) related with benign prostatic hyperplasia (BPH) are present nowadays in approximately 20 to 30% of the Spanish male population from the age of 50 onwards. The purpose of this study was to assess clinical and epidemiological characteristics of patients with LUTS. METHODS: A cross-sectional study was performed, between 1999 and 2000, among 1,804 men aged 40 or older who were living in Madrid. Subjects were interviewed by telephone; socio-demographic information was requested and the presence of LUTS was assessed using the International Prostate Symptoms Score. Informed consent was requested, Association between qualitative variables was evaluated by chi2 or Fisher's test. A logistic regression model was performed to control confusion. RESULTS: Prevalence of moderate/severe LUTS was 16.6% (95%CI: 14.8-18.3). Nearly 90% of the subjects consumed olive oil, 71.5% alcohol, 63.1% did not smoke and 96.9% did not consume drugs. A 27.7% of the subjects had hypertension and 8.8% referred diabetes. Men aged 70 or older had a threefold increased frequency of serious symptoms compared to younger men (OR: 3.31; 95%CI: 2.10-5.22). Low level of studies increased this frequency by a factor of 2.2 (95%CI: 1.42-3.46) and men who consumed only seed oil had twice more serious symptoms than those who consumed olive oil (OR: 1.86; 95%CI: 0.98-3.55). CONCLUSIONS: Family history of urological diseases, age, low level of studies, hypertension, diabetes and seed oil consumption were independently associated with more serious symptoms, while medium alcohol consumption and mild smoking habit were associated with slighter symptoms.

[Vaccination coverage against Streptococcus pneumoniae in splenectomized patients in a fourth-level hospital (1999-2004)]. / Evolución de la cobertura vacunal frente a Streptococcus pneumoniae en pacientes esplenectomizados en un hospital de cuarto nivel (1999-2004).

INTRODUCTION: Patients in whom the spleen has been removed have a higher risk of acquiring infection by capsulated microorganisms, particularly Streptococcus pneumoniae, Haemophilus influenzae type b, and Neisseria meningitidis. AIMS: Determine the vaccination coverage against S. pneumoniae of splenectomized patients in Hospital Clínico San Carlos (HCSC, Madrid) and to identify variables related to the level of vaccination coverage reached. METHODS: From January 1, 1999 to December 31, 2004, a retrospective cohort study of all splenectomized patients was carried out in HCSC. Patients were identified from the Medical Records Department and the vaccination registry of the Preventive Medicine Service. RESULTS: During the study period, 248 splenectomies were carried out. The median age was 61.0 years (interquartile range, 39.0-71.0). The most frequent reason for splenectomy was malignant gastrointestinal neoplasm (34.7%). Overall vaccination coverage against S. pneumoniae for the period studied was 48.4%. A significant increase in vaccination coverage per year was observed (P < .001). Multivariate analysis identified the following variables associated with a greater risk of not being vaccinated: male sex, patients proceeding from surgical services, and patients undergoing splenectomy during 1999 to 2001. CONCLUSIONS: Vaccination coverage has increased every year since implementation of the protocol. Nevertheless, it necessary to extend the vaccination program within daily clinical practice.
