RESUMO

It is known that the growth of prostate metastatic bone tumor depends on androgens, and tumor formation can start from migratory malignant cells produced in that organ. These cells exhibit grater type 1 5α-reductase (5α-R1) activity than type 2 5α-reductase. Noteworthy, both isozymes convert testosterone (T) to the more active androgen dihydrotestosterone (DHT) in the target tissues. Thus, in order to potentially improve the prognosis of this disease, in this work, seven derivatives of 17-(1H-benzimidazol-1-yl)-16-formillandrosta-5,16-dien-3ß-yl benzoate (4a-f) and 17-(1H-benzimidazol-1-yl)-3-hydroxy-16-formylandrost-5,16-diene (4) were synthesized, characterized and identified as inhibitors of type 1 5α-reductase (5αR1). These derivatives having the advantage of improved plasma half-life. The inhibitory activity of the compounds towards 5α-R1 isoenzyme was determined by conversion of T into DHT in the presence or absence of compounds 4, 4a-f. Further, in vivo experiments were also carried out, treating gonadectomized hamsters with T and/or 4, 4a-f and evaluating their effect on the diameter of hamster flank organs and on the weight of the prostatic and seminal vesicles. Results indicated that compounds 4, 4b, 4c, served as in vitro inhibitors of the enzyme 5α-R1 and pharmacological experiments showed that 4 and derivatives 4a-f decreased the diameter of the flank glands, the weight of the prostate and seminal vesicles of treated hamsters without any appreciable toxicity during observation. Noteworthy the fact that compound 4 is the product, in all cases, of the hydrolysis of the series of esters 4a-f, thus they can serve as precursors (prodrugs) of the active form 4.

RESUMO

The aim of this study was to synthesize several 16-dehydropregnenolone derivatives containing an imidazole ring at C-21 and a different ester moiety at C-3 as inhibitors of 5α-reductase 1 and 2 isoenzymes. Their binding capacity to the androgen receptor (AR) was also studied. Additionally, we evaluated their pharmacological effect in a castrated hamster model and their cytotoxic activity on a panel of cancer cells (PC-3, MCF7, SK-LU-1). The results showed that only the derivatives with an alicyclic ester at C-3 showed 5α-R2 enzyme inhibition activity, the most potent of them being 21-(1H-imidazol-1-yl)-20-oxopregna-5,16-dien-3ß-yl-cyclohexanecarboxylate with an IC50 of 29nM. This is important because prostatic benign hyperplasia is directly associated with the presence of 5α-R2. However, all the derivatives failed to inhibit 5α-R1 or bind to the AR. These alicyclic ester derivatives decreased the weight and size of androgen-dependent glands in the hamster, indicating they are very active in vivo and are not toxic. In addition, the 21-(1H-imidazol-1-yl)-20-oxopregna-5,16-dien-3ß-yl-acetate derivative showed the highest cytotoxic activity on the three cancer cell lines studied. It is therefore important in the synthesis of steroidal compounds to consider the size of the ester moiety at C-3 of the steroid skeleton, which is key in obtaining biological activity, as observed in this experiment.

RESUMO

AIMS: To ascertain the formalities and procedures required for the prescription of PCSK9 inhibitors in the cardiology departments of Spanish hospitals, making proposals for improvement to optimize the prescription process. METHODS: A first phase of collecting information about the variables and administrative procedures required for the prescription of PCK9 inhibitors and the elaboration of a specific questionnaire and a second phase of collecting data with an online self-administered questionnaire. RESULTS: A total of 88 hospitals participated in the study (mean number of beds 625; mean number of cardiologists 18 ± 10; 78% university hospitals). There was underuse of PCSK9 inhibitors (real prescription of 30 treatments/year; potential prescription of 80), mainly because of not fulfilling the therapeutic positioning report (52%) and application refusal (31%). Beyond the requirements of the therapeutic positioning report, 1.2 ± 0.4 applications are required with 8.5 ± 4.2 variables. Only 21% of hospitals did not require a previous authorization process and in the remaining hospitals, approval from a committee was necessary. The accumulated time of the prescription process was 6 weeks. Discontinuation rates during follow-up were 9% ± 12%. CONCLUSIONS: Treatment with PCSK9 inhibitors is clearly underused in Spain. This is mainly due to both inappropriate identification of patients, and complex administrative procedures that could inhibit/discourage prescription by cardiologists and consequently, limit their use. In addition, there is a substantial delay from drug approval tadministration.

RESUMO

Aims: To analyze the impact of implementing three different models of continuity of care on the delay of first visits to the cardiologist (management end point) and on LDL-cholesterol control rates among patients with atherosclerotic vascular disease (clinical end point). Methods: Observational, longitudinal and retrospective study of patients with cardiovascular disease and LDL-cholesterol ≥70 mg/dl attended in three hospitals (H1/H2/H3). In H1 and H2, a virtual system (telecardiology) was developed (in H1, internal audits and specific medical education were also performed). In H3 a cardiologist was integrated into the primary care center. Results: The delay of visits to cardiologist significantly improved from 66.5 ± 29.1 days to 34.1 ± 14.1 days (p < 0.001), as well as the intensification of lipid-lowering treatment and the achievement of lipid goals. LDL-cholesterol control rates were higher in H1 and the reduction of the delay of visits in H3. Conclusion: Continuity of care is associated with improvements in management and clinical end points.

RESUMO

The coronavirus disease 2019 (COVID-19) pandemic has changed how we view our consultations. To reduce the risk of spread in the most vulnerable patients (those with heart disease) and health personnel, most face-to-face consultations have been replaced by telemedicine consultations. Although this change has been rapidly introduced, it will most likely become a permanent feature of clinical practice. Nevertheless, there remain serious doubts about organizational and legal issues, as well as the possibilities for improvement etc. In this consensus document of the Spanish Society of Cardiology, we attempt to provide some keys to improve the quality of care in this new way of working, reviewing the most frequent heart diseases attended in the cardiology outpatient clinic and proposing some minimal conditions for this health care process. These heart diseases are ischemic heart disease, heart failure, and arrhythmias. In these 3 scenarios, we attempt to clarify the basic issues that must be checked during the telephone interview, describe the patients who should attend in person, and identify the criteria to refer patients for follow-up in primary care. This document also describes some improvements that can be introduced in telemedicine consultations to improve patient care.

RESUMO

Considerable progress has been made in learning about the physiology and biochemistry of the sebaceous glands and several of the diseases that affect this component of the skin. Of these diseases, acne has particular importance. It is associated with adolescence, and because of the hormonal changes that take place in this stage, when it is severe it can cause depression. Moreover, in a considerable proportion of acne sufferers both adolescent and adult, it can produce tumors and deformation of the sebaceous glands. This seriously affects the sufferers to the point where it may limit their professional activities because they do not want to be seen in public. Several important issues from classic studies on the sebaceous gland will be reviewed in this document to report the state of the art of current treatments for the pathology of these glands. The sebaceous gland is an intracrine organ, capable of synthesizing and metabolizing different steroidal hormones. The role of each of the enzymes involved in these processes of the skin will be analyzed. The presence of different hormone receptors in the scientific literature will be also reviewed, due to the role of the sebaceous gland in lipogenesis at different ages. We also describe the mechanism of action of androgens and progestins in relation to coregulators recruited for lipogenesis in this gland. We propose several new steroidal compounds based on their mechanism of action to block lipogenesis in the sebaceous glands. These molecules offer potential for new treatment options for skin diseases.

RESUMO

To compare vaginal colonization by genital micoplasmas in pregnant and non pregnant women and to determine the association between pregnancy and colonization by these microorganisms, samples of exocervix an endocervix from pregnant (n = 80) and non pregnant (n = 65) women, from two health centers of Maracaibo, Zulia State, Venezuela were processed. The Mycoplasma-Lyo kit (bioMérieux laboratories) was used for the culture and identification of genital micoplasmas. In pregnant women, prevalences of 10% for M. hominis and 26.25% for Ureaplasma spp. were found; 35.38% for M. hominis and 20% for Ureaplasma spp. in non-pregnant, were obtained. Among the pregnant, Ureaplasma spp. was the most frequently isolated micoplasma, in symptomatic and asymptomatic; while in the non pregnant group, M. hominis was more common among the symptomatic patients; only one case (1.54%) was an asymptomatic carrier of Ureaplasma spp. The highest positivity percentages were obtained in primigravidas (48.71%) and during the second gestational trimester (34.21%). No statistically significant differences were found between vaginal colonization by genital micoplasmas according to age, number of pregnancy and gestational trimester; but they were found between the presented symptomatology and vaginal colonization by genital micoplasmas. Genital micoplasmas were isolated from gravid women at approximately the same recovery rate as in non-pregnant women; being M. hominis the most frequently isolated in non-pregnant women and Ureaplasma spp. in the pregnant group.

RESUMO

Acetylsalicylic acid (ASA) and clopidogrel combined therapy has been reported to be beneficial in patients with acute coronary syndrome (ACS). Antiplatelet drug resistance, especially to clopidogrel, is a multifactorial phenomenon that affects a large number of ACS patients. The genetic contribution to this drug response is not fully elucidated. We investigated the relationship of ABC-type efflux subfamily C member 3 (ABCC3) polymorphisms and mRNA expression with plasma concentrations of clopidogrel, salicylic acid (SA) and a carboxylic acid metabolite (CAM). Clopidogrel, CAM and SA plasma concentrations were measured simultaneously by liquid chromatography-tandem mass spectrometry (LCMS/MS) from 83 ACS patients undergoing percutaneous coronary intervention. ABCC3 (rs757421, rs733392 and rs739923) and CYP2C19*2 (rs4244285) polymorphisms as well as mRNA expression were evaluated. A positive correlation was found between CAM concentrations and ABCC3 mRNA expression (r = 0.494, p < 0.0001). Patients carrying genotype AA (rs757421 variant) had higher CAM concentrations and ABCC3 mRNA expression as compared to those of GG + GA carriers (p = 0.017). A multiple linear regression analysis revealed that ABCC3 mRNA expression (p = 0.017), rs757421 AA genotype (p = 0.001), blood collection time (p = 0.018) and clopidogrel dose (p = 0.001) contributed to the concentration of CAM. No associations were observed for the CYP2C19*2 polymorphism. These results suggest that up-regulation of ABCC3 mRNA expression leads to increased plasma CAM levels through MRP3-mediated cell efflux. The ABCC3 rs757421 polymorphism may contribute to gene expression. Therefore, ABCC3 may be a potential biomarker for the response to clopidogrel.

RESUMO

Objetivos: Conocer las tramitaciones y gestiones requeridas en la prescripción del tratamiento con inhibidores PCSK9 en los servicios de cardiología de los hospitales españoles, haciendo propuestas de mejoras para optimizar el proceso de prescripción. Métodos: Una primera fase de recogida de información sobre variables y procedimientos administrativos requeridos en la prescripción de inhibidores PCSK9 y elaboración de un cuestionario específico. Una segunda fase de recogida de datos a través de un cuestionario electrónico autoadministrado. Resultados: Participaron 88 hospitales (número medio de camas 625; número medio de cardiólogos 18 ± 10; 78% hospitales universitarios). Hubo una infrautilización de inhibidores PCSK9 (prescripción real 30 tratamientos/año; prescripción potencial 80), principalmente por no cumplir con informe de posicionamiento terapéutico (52%), con la denegación de solicitud en un 31%. Se requirieron una media de 1,2 ± 0,4 formularios, con un promedio de 8,5 ± 4,2 variables, además de los requisitos del informe de posicionamiento terapéutico. Solo en el 21% de los hospitales no es necesario un proceso de autorización previa, y en el resto es necesaria la aprobación por una comisión. El tiempo acumulado en el proceso de prescripción es de seis semanas. La discontinuación del tratamiento durante el seguimiento es de 9 ± 12%. Conclusiones: Los inhibidores PCSK9 se encuentran claramente infrautilizados en España. Esto se debe a una incorrecta identificación de los pacientes, y a la existencia de complejos procedimientos de tipo administrativo que podrían inhibir/desmotivar su prescripción por parte de los cardiólogos, y consecuentemente, limitar su prescripción. Asimismo, existe un retraso notable desde la aprobación del fármaco hasta su administración.(AU)

RESUMO

La pandemia producida por la infección por el coronavirus SARS-CoV-2 (COVID-19) ha cambiado la forma de entender nuestras consultas. Para reducir el riesgo de contagio de los pacientes más vulnerables (aquellos con cardiopatías) y del personal sanitario, se han suspendido la mayoría de las consultas presenciales y se han puesto en marcha las consultas telemáticas. Este cambio se ha implementado en muy poco tiempo, pero parece que ha venido para quedarse. No obstante, hay grandes dudas sobre aspectos organizativos, legales, posibilidades de mejora, etc. En este documento de consenso de la Sociedad Española de Cardiología, tratamos de dar las claves para mejorar la calidad asistencial en nuestras nuevas consultas telemáticas, revisando las afecciones que el cardiólogo clínico atiende con más frecuencia en su consulta ambulatoria y proponiendo unos mínimos en ese proceso asistencial. Estas enfermedades son la cardiopatía isquémica, la insuficiencia cardiaca y las arritmias. En los 3 escenarios tratamos de clarificar los aspectos fundamentales que hay que revisar en la entrevista telefónica, a qué pacientes habrá que atender en una consulta presencial y cuáles serán los criterios para su seguimiento en atención primaria. El documento también recoge distintas mejoras que pueden introducirse en la consulta telemática para mejorar la asistencia de nuestros pacientes

RESUMO

UNLABELLED: Although numerous studies have established the utility of 4 F catheters for routine coronary angiography, its adequacy for automatic quantitative coronary analysis has not been previously assessed. METHODS: In 32 consecutive patients, coronary angiography was performed sequentially with 4 F diagnostic catheters and 6 F guiding catheters after intracoronary nitroglycerin. A total of 43 lesions were evaluated for quantitative analysis using both types of catheter as scaling devices. Possible differences in the reference diameter, minimal luminal diameter and percent diameter stenosis were evaluated. All measurements were performed offline by the same operator and intraobserver variability estimation was performed by repeating the evaluation in 12 lesions randomly selected after 1 month. RESULTS: The mean reference diameter was 2.98+/-0.48 mm, mean minimal luminal diameter was 1.00+/-0.52 mm and percent diameter stenosis was 67.1+/-15.3%. Accuracy (mean difference of values) was 0.009 mm for reference diameter, 0.005 mm for minimal luminal diameter and 0.25% for percent diameter stenosis. Precision (mean standard deviation of the differences) was 0.17 mm for reference diameter, 0.19 mm for minimal luminal diameter and 5.93% for percent stenosis. Linear correlation for these three variables was 0.94, 0.93 and 0.93, respectively. Intraobserver variability analysis showed similar values for accuracy, precision and linear correlation. CONCLUSIONS: Angiography with 4 F catheters allows adequate quantification of luminal diameters as compared to most accepted clinical standards. These results may have implications for the selection of diagnostic catheters for routine follow-up assessment of percutaneous coronary interventions.

RESUMO

Fractional flow reserve, as determined with a pressure-wire, was validated in the assessment of the functional severity of intermediate lesions in a population with stable ischemic cardiopathy. The value of pressure-wire analysis in acute coronary syndrome is unknown. We report two patients with acute coronary syndrome, in which the therapeutic approach was guided by the fractional flow reserve. We discuss the utility of this tool in this context.

RESUMO

INTRODUCTION AND OBJECTIVES: Experience with 4 F catheters in cardiac catheterization is limited. These devices appear to be more suitable for the radial artery approach than conventional 6 F catheters. METHODS: We analyze our preliminary experience with diagnostic catheterization of the radial artery with 4 F catheters. Angiographic images were evaluated using a predefined scale (1. poor; 2. acceptable; 3. optimal). In a subgroup of patients who underwent coronary angioplasty, the quantitative angiographic data obtained with the 4 F catheter were compared to those obtained with the 6 F guide catheter. In all cases the patients were clinically followed-up at 24 h and 7 days. RESULTS: Two hundred and six studies performed over a 12-month period were reviewed. In 6 cases (2.9%) the femoral vein had to be used instead and in 4 cases (1.9%) the 4 F catheters were replaced by 6 F catheters. The left coronary angiography was graded as optimal in 83% and as acceptable in 15%. Right coronary artery images were considered optimal in 93% and acceptable in 7%. There was an excellent correlation between the reference diameter obtained by quantitative angiography with the 4 F catheter and values obtained with a 6 F guide catheter (r = 0.92; p < 0.01). No major vascular complications occurred. CONCLUSION: 4 F catheters are appropriate for systematic use in diagnostic procedures using the radial access.

Método: estudio descriptivo a partir de la revisión y análisis sistemático de estudios originales primarios sobre estrategias de promoción de la salud y estilos de vida saludables, haciendo uso de la lista de control PRISMA. Resultados: se identificaron tres estrategias de PS para el fomento de EVS, estas se basaron en información, educación, cambio de actitudes, fortalecimiento de la autoestima y toma de decisiones a través de salud móvil, técnicas de motivación, talleres prácticos y psicoeducación. Conclusiones: el desarrollo de estrategias que promueven estilos de vida saludables es incipiente en escenarios como el lugar de trabajo y la familia, lo cual genera una baja cobertura poblacional y demanda acciones interdisciplinarias desde diferentes campos como el de la Psicología de la Salud.


Abstract Objective: To analyze Health Promotion (HP) strategies for the encouragement of healthy lifestyles (EHL) in family, work, community, education and the health sector scenarios. Method: descriptive study based on the systematic review and analysis of primary original studies on health promotion strategies in healthy lifestyles, making use of the PRISMA checklist. Results: three HP strategies were identified for the promotion of EHL which were based on information, education, change of attitudes, strengthening of self-esteem and decision making through mobile health, motivation techniques, practical workshops and psychoeducation. Conclusions: the development of strategies that promote healthy lifestyles is incipient in scenarios such as the workplace and the family, which generates low population coverage and demands interdisciplinary actions from different fields such as the Psychology of health.
