A Genomic Snapshot of the SARS-CoV-2 Pandemic in the Balearic Islands

7 páginas, 3 figurasObjective: To analyze the SARS-CoV-2 genomic epidemiology in the Balearic Islands, a unique setting in which the course of the pandemic has been influenced by a complex interplay between insularity, severe social restrictions and tourism travels. Methods: Since the onset of the pandemic, more than 2,700 SARS-CoV-2 positive respiratory samples have been randomly selected and sequenced in the Balearic Islands. Genetic diversity of circulating variants was assessed by lineage assignment of consensus whole genome sequences with PANGOLIN and investigation of additional spike mutations. Results: Consensus sequences were assigned to 46 different PANGO lineages and 75% of genomes were classified within a VOC, VUI, or VUM variant according to the WHO definitions. Highest genetic diversity was documented in the island of Majorca (42 different lineages detected). Globally, lineages B.1.1.7 and B.1.617.2/AY.X were identified as the 2 major lineages circulating in the Balearic Islands during the pandemic, distantly followed by lineages B.1.177/B.1.177.X. However, in Ibiza/Formentera lineage distribution was slightly different and lineage B.1.221 was the third most prevalent. Temporal distribution analysis showed that B.1 and B.1.5 lineages dominated the first epidemic wave, lineage B.1.177 dominated the second and third, and lineage B.1.617.2 the fourth. Of note, lineage B.1.1.7 became the most prevalent circulating lineage during first half of 2021; however, it was not associated with an increased in COVID-19 cases likely due to severe social restrictions and limited travels. Additional spike mutations were rarely documented with the exception of mutation S:Q613H which has been detected in several genomes (n = 25) since July 2021. Conclusion: Virus evolution, mainly driven by the acquisition and selection of spike substitutions conferring biological advantages, social restrictions, and size population are apparently key factors for explaining the epidemic patterns registered in the Balearic Islands.This work has been supported by the Instituto de Salud Carlos III of Spain through the project COV20/00140: Addressing unknowns of COVID-19 transmission and infection combining pathogen genomics and epidemiology to inform public health interventions and European Union HERA Incubator program through grant ECDC/HERA/2021/024 ECD.12241.

Effectiveness of an intervention for improving drug prescription in primary care patients with multimorbidity and polypharmacy:Study protocol of a cluster randomized clinical trial (Multi-PAP project)

This study was funded by the Fondo de Investigaciones Sanitarias ISCIII (Grant Numbers PI15/00276, PI15/00572, PI15/00996), REDISSEC (Project Numbers RD12/0001/0012, RD16/0001/0005), and the European Regional Development Fund ("A way to build Europe").Background: Multimorbidity is associated with negative effects both on people's health and on healthcare systems. A key problem linked to multimorbidity is polypharmacy, which in turn is associated with increased risk of partly preventable adverse effects, including mortality. The Ariadne principles describe a model of care based on a thorough assessment of diseases, treatments (and potential interactions), clinical status, context and preferences of patients with multimorbidity, with the aim of prioritizing and sharing realistic treatment goals that guide an individualized management. The aim of this study is to evaluate the effectiveness of a complex intervention that implements the Ariadne principles in a population of young-old patients with multimorbidity and polypharmacy. The intervention seeks to improve the appropriateness of prescribing in primary care (PC), as measured by the medication appropriateness index (MAI) score at 6 and 12months, as compared with usual care. Methods/Design: Design:pragmatic cluster randomized clinical trial. Unit of randomization: family physician (FP). Unit of analysis: patient. Scope: PC health centres in three autonomous communities: Aragon, Madrid, and Andalusia (Spain). Population: patients aged 65-74years with multimorbidity (≥3 chronic diseases) and polypharmacy (≥5 drugs prescribed in ≥3months). Sample size: n=400 (200 per study arm). Intervention: complex intervention based on the implementation of the Ariadne principles with two components: (1) FP training and (2) FP-patient interview. Outcomes: MAI score, health services use, quality of life (Euroqol 5D-5L), pharmacotherapy and adherence to treatment (Morisky-Green, Haynes-Sackett), and clinical and socio-demographic variables. Statistical analysis: primary outcome is the difference in MAI score between T0 and T1 and corresponding 95% confidence interval. Adjustment for confounding factors will be performed by multilevel analysis. All analyses will be carried out in accordance with the intention-to-treat principle. Discussion: It is essential to provide evidence concerning interventions on PC patients with polypharmacy and multimorbidity, conducted in the context of routine clinical practice, and involving young-old patients with significant potential for preventing negative health outcomes.

Concordance of congenital heart defects in two pairs of monozygotic twins: pulmonary stenosis and tetralogy of Fallot

Two pairs of twins with specific concordance in congenital heart lesions are presented. We reviewed all the monozygotic twins with specific concordance in congenital heart lesions in the last 18 years. Two pairs were found. First, a pair of 13 years-old monozygotic female twins; a severe infundibular and pulmonary valve stenosis was discovered in both girls. In the second pair of twins (8 years-old boys), Tetralogy of Fallot was diagnosed by echocardiogram, cardiac catheterization and angicardiography. In fluorescence hybridization test in situ all patients were negative for microdeletion in chromosome 22q11. Anatomic differences between twins are not enough explained on genetic bases; it's necessary to consider the role of other factors, probably acquired during the first stages of embryonic development. These are the two first pairs of twins with specific concordance in congenital cardiac lesions reported in Mexico

Anomalous origin of the Left Coronary Artery from the Pulmonary Artery. Echocardiographic diagnosis

The experience with echocardiographic diagnosis of five cases of Anomalous Origin of the Left Coronary Artery from the Pulmonary Artery (ALCAPA) is reviewed. Material and Methods. all cases with a diagnosis of ALCAPA during a 10 year period were included. Results. two age groups were clearly identified: infants and older patients. In the former, the echocardiographic findings included a dilated left ventricle with low ejection fraction (19% and 26%), mitral regurgitation, dilated right coronary artery and difficulties in identifying the origin of the left coronary artery. An 11-year-old asymptomatic boy, a 17-year-old young woman with dyspnea on effort and a 55-year-old woman with angina formed the older group. In these three cases, an abnormal upward flow was detected within the ventricular septum related to the collaterals and the inverse flow of the anterior descending artery. A reverse flow within the origin of the left coronary artery, probably related to an origin in the pulmonary artery, was observed. In all five cases the diagnosis was corroborated using selective right coronary artery angiography. Conclusions: In the infants, the dilated left ventricle with impaired systolic function, mitral regurgitation and dilated right coronary artery make it necessary to discard the ALCAPA diagnosis. In the older group, even in asymptomatic patients, an abnormal ascending flow within the ventricular septum, combined with a dilated coronary artery, was the most reliable echocardiographic evidence for a diagnosis of ALCAPA

Rabdomioma cardiaco tratado quirúrgicamente con éxito y revisión de la literatura

Los tumores cardiacos primarios son raros, con incidencia variable en todas las edades del 0.005 al 0.05%. En pacientes pediátricos, la incidencia es del 0.27%. Los tumores más frecuentes durante la infancia son los rabdomiomas cardiacos, considerados como benignos. Aunque la expresión clínica es amplia, en la mayoría de los casos son asintomáticos y se detectan por la presencia de soplos. En la etapa prenatal se manifiestan con arritmias o hydrops fetalis. En algunos neonatos y lactantes se encuentran arritmias, datos de bajo gasto cardíaco o muerte súbita. La asociación con esclerosis tuberosa se ha observado hasta en un 81%. Se presenta el caso de paciente masculino neonato, con diagnóstico de rabdomioma cardiaco que inicialmente estaba asintomático, sin embargo en el seguimiento requirió de tratamiento quirúrgico a los 5 meses de edad, por datos de insuficiencia cardiaca secundaria a obstrucción del tracto de salida del ventrículo derecho. A 5 meses de la cirugía, el paciente está asintomátic

Fístula coronaria congénita: Presentación de siete casos y revisión de la literatura

Las fístulas coronarias son raras; sin embargo, pueden expresarse con cualquier manifestación cardiovascular. El cuadro clínico y la repercusión hemodinámica son diferentes en los adultos cuando se comparan con los de los niños. Material y métodos: Se presenta la experiencia que tuvo lugar entre el año 2000 y 2007 en un hospital de concentración de cardiología de enfermos con fístula coronaria, demostrada por coronariografía selectiva. Se incluyeron siete casos, tres adultos y cuatro niños; la media de edad de los niños fue de 6.5 años y la de los adultos de 25.6 años. En tres de los pediátricos, la fístula se originó de la coronaria izquierda y terminaban dos en la arteria pulmonar y uno en la aurícula derecha, en tanto que la originada en la coronaria derecha terminó en el ventrículo derecho. En los tres adultos, el origen fue en la coronaria derecha, dos de ellas abrían al ventrículo derecho y la otra terminaba en el seno coronario. Dos niños se operaron con éxito y están asintomáticos a 1 y 4 años de la operación, mientras que el adulto operado tuvo un infarto diafragmático no complicado 4 semanas después de la operación. Se hizo una revisión del tema en la literatura y se contrastó con lo visto en esta serie. Conclusiones: El cuadro clínico y la repercusión hemodinámica son más graves en los adultos. La coronariografía selectiva es el estándar de oro. El tratamiento quirúrgico tiene baja morbilidad y mortalidad
