Incidence of atrial fibrillation in pregnancy and clinical significance: A meta-analysis.
CONCLUSION: The overall estimated incidence of AF and recurrent AF during pregnancy is as high as 2.2% and 39.2%, respectively. AF during pregnancy may result in poor maternal and fetal outcomes. PMID: 31521944 [PubMed - as supplied by publisher]
We report that Tbx5 and Gata4 interact with opposite signs for atrial rhythm controls compared with cardiac development. Using mouse genetics, we found that AF pathophysiology caused by Tbx5 haploinsufficiency, including atrial arrhythmia susceptibility, prolonged action potential duration, and ectopic cardiomyocyte depolarizations, were all rescued by Gata4 haploinsufficiency. In contrast, Nkx2-5 haploinsufficiency showed no combinatorial effect. The molecular basis of the TBX5/GATA4 interaction included normalization of intra-cardiomyocyte calcium flux and expression of calcium channel genes Atp2a2 and Ryr2. Furthermore,...
Molecular heterogeneity of endothelial cells underlies their highly specialized functions during changing physiological conditions within diverse vascular beds. For example, placental spiral arteries (SAs) undergo remarkable remodeling to meet the ever-growing demands of the fetus — a process which is deficient in preeclampsia. The extent to which maternal endothelial cells coordinate with immune cells and pregnancy hormones to promote SA remodeling remains largely unknown. Here we found that remodeled SAs expressed the lymphatic markers PROX1, LYVE1, and VEGFR3, mimicking lymphatic identity. Uterine natural killer (...
Conclusion: Septic patients with a past history of heart failure received 1L less IV fluids in the first 24 hours with no difference in mortality.
RESUMO A sepse persiste como importante sobrecarga à saúde pública nos Estados Unidos e em todo o mundo. Com o crescente uso de tecnologias laboratoriais, tem se renovado o interesse na utilização de biomarcadores na sepse, para auxiliar em um processo mais preciso e direcionado para tomadas de decisão. Os peptídeos natriuréticos vem sendo c ada vez mais reconhecidos por seu papel que vai além da insuficiência cardíaca. Estes peptídeos estão comumente elevados em pacientes críticos que apresentam condições de disf...
Transcervical radiofrequency ablation of uterine fibroids is an incisionless procedure to treat nonpedunculated uterine fibroids, including those that are not amenable to operative hysteroscopy. However, its safety and effectiveness regarding fertility and fecundity have not been established, including among women with infertility. This is a report of a pregnancy that occurred in a woman after transcervical radiofrequency (RF) ablation of uterine fibroids and assisted reproduction.
