Anticoncepción hormonal en mujeres jóvenes con enfermedades reumatológicas

Antecedentes: Las enfermedades reumatológicas (ER) se presentan con mayor frecuencia en mujeres en edad fértil. Es durante este período que muchas mujeres consultan por trastornos de los flujos rojos, dismenorrea y prevención del embarazo. Objetivo: Realizar una puesta al día del uso de anticoncepción hormonal (AH) en mujeres jóvenes con ER, especialmente en las portadoras de lupus eritematoso sistémico (LES) y artritis reumatoide (AR). Método: Se revisó la literatura en Pubmed para los términos AH en ER, con especial énfasis en guías clínicas y ensayos clínicos aleatorizados. Resultados: El uso de AH en pacientes con LES inactivo o con actividad leve no ha mostrado un empeoramiento de la enfermedad. Tampoco existe evidencia categórica que demuestre un mayor riesgo trombótico en aquellas con anticuerpos antifosfolípidos negativos, para las cuales se recomienda el uso de cualquier tipo de AH. En pacientes con AR no se ha demostrado asociación del uso de AH y aumento de la actividad de la enfermedad. Además la interacción farmacológica entre AH y medicamentos reumatológicos es mínima. Existe escasa evidencia del uso de AH en mujeres menores de 18 años con ER. Conclusión: Basado en la evidencia disponible las pacientes con ER con anticuerpos antifosfolípidos negativos podrán utilizar AH según los criterios de la OMS, lo que abre las puertas a mayores alternativas terapéuticas y prevención de embarazo para estas adolescentes y mujeres jóvenes con ER

Impact of COVID-19 on cardiovascular testing in the United States versus the rest of the world

Objectives: This study sought to quantify and compare the decline in volumes of cardiovascular procedures between the United States and non-US institutions during the early phase of the coronavirus disease-2019 (COVID-19) pandemic. Background: The COVID-19 pandemic has disrupted the care of many non-COVID-19 illnesses. Reductions in diagnostic cardiovascular testing around the world have led to concerns over the implications of reduced testing for cardiovascular disease (CVD) morbidity and mortality. Methods: Data were submitted to the INCAPS-COVID (International Atomic Energy Agency Non-Invasive Cardiology Protocols Study of COVID-19), a multinational registry comprising 909 institutions in 108 countries (including 155 facilities in 40 U.S. states), assessing the impact of the COVID-19 pandemic on volumes of diagnostic cardiovascular procedures. Data were obtained for April 2020 and compared with volumes of baseline procedures from March 2019. We compared laboratory characteristics, practices, and procedure volumes between U.S. and non-U.S. facilities and between U.S. geographic regions and identified factors associated with volume reduction in the United States. Results: Reductions in the volumes of procedures in the United States were similar to those in non-U.S. facilities (68% vs. 63%, respectively; p = 0.237), although U.S. facilities reported greater reductions in invasive coronary angiography (69% vs. 53%, respectively; p < 0.001). Significantly more U.S. facilities reported increased use of telehealth and patient screening measures than non-U.S. facilities, such as temperature checks, symptom screenings, and COVID-19 testing. Reductions in volumes of procedures differed between U.S. regions, with larger declines observed in the Northeast (76%) and Midwest (74%) than in the South (62%) and West (44%). Prevalence of COVID-19, staff redeployments, outpatient centers, and urban centers were associated with greater reductions in volume in U.S. facilities in a multivariable analysis. Conclusions: We observed marked reductions in U.S. cardiovascular testing in the early phase of the pandemic and significant variability between U.S. regions. The association between reductions of volumes and COVID-19 prevalence in the United States highlighted the need for proactive efforts to maintain access to cardiovascular testing in areas most affected by outbreaks of COVID-19 infection

Mirada iberoamericana a las políticas de ciencia, tecnología e innovación : perspectivas comparadas

El presente libro aporta al campo de los estudios sociales de la ciencia, la tecnología y la innovación, mediante el análisis comparado de los Planes de Ciencia Tecnología e Innovación (PCTI), tratando de superar el enfoque dominante que privilegia los casos nacionales independientes que ha limitado el debate académico. Considera tanto estudios sobre las dinámicas de su institucionalización, el papel de los diversos actores, las contribuciones del campo a la concepción de las políticas y los desafíos que se presentan a las PCTI para responder a los imperativos de democratización, inclusión y sustentabilidad

Host genetic variation influences the development of illness requiring critical care or hospitalization after infection with SARS-CoV-2. The GenOMICC (Genetics of Mortality in Critical Care) study enables the comparison of genomes from individuals who are critically ill with those of population controls to find underlying disease mechanisms. Here we use whole-genome sequencing in 7,491 critically ill individuals compared with 48,400 controls to discover and replicate 23 independent variants that significantly predispose to critical COVID-19. We identify 16 new independent associations, including variants within genes that are involved in interferon signalling (IL10RB and PLSCR1), leucocyte differentiation (BCL11A) and blood-type antigen secretor status (FUT2). Using transcriptome-wide association and colocalization to infer the effect of gene expression on disease severity, we find evidence that implicates multiple genes-including reduced expression of a membrane flippase (ATP11A), and increased expression of a mucin (MUC1)-in critical disease. Mendelian randomization provides evidence in support of causal roles for myeloid cell adhesion molecules (SELE, ICAM5 and CD209) and the coagulation factor F8, all of which are potentially druggable targets. Our results are broadly consistent with a multi-component model of COVID-19 pathophysiology, in which at least two distinct mechanisms can predispose to life-threatening disease: failure to control viral replication; or an enhanced tendency towards pulmonary inflammation and intravascular coagulation. We show that comparison between cases of critical illness and population controls is highly efficient for the detection of therapeutically relevant mechanisms of disease
