Risk of thromboembolism in patients with COVID-19 who are using hormonal contraception.

Background: The novel coronavirus disease (COVID-19) has led to significant mortality and morbidity, including a high incidence of related thrombotic events. There has been concern regarding hormonal contraception use during the COVID-19 pandemic, as this is an independent risk factor for thrombosis, particularly with estrogen-containing formulations. However, higher estrogen levels may be protective against severe COVID-19 disease.

Risk of thromboembolism in patients with COVID-19 who are using hormonal contraception: a Cochrane systematic review.

Background: The coronavirus disease COVID-19 is associated with an increased risk of thrombotic events. Individuals with COVID-19 using hormonal contraception could be at additional risk for thromboembolism, but evidence is sparse.

Methods: We conducted a systematic review on the risk of thromboembolism with hormonal contraception use in women aged 15-51 years with COVID-19.

Satisfaction, Resignation, and Dissatisfaction with Long-Acting Reversible Contraception among Low-Income Postpartum Texans.

Introduction: Prior longitudinal studies of long-acting reversible contraception (LARC) satisfaction and continuation guaranteed their participants access to LARC removal. Under real-world conditions, LARC users who wish to discontinue may experience barriers to LARC removal.

Methods: A prospective cohort study recruited 1,700 postpartum Texans without private insurance from 8 hospitals in 6 cities.

What Impacts HPV Vaccination Recommendations? An Exploration of Medical Residents' Knowledge, Training, Barriers, and Practices.

Background And Objectives: Increasing human papillomavirus vaccination (HPVV) uptake is critical to the prevention of cervical cancer. Effective physician communication and clinical workflow policies have a significant impact on vaccination rates. However, resident training programs vary in the inclusion of training in effective HPVV practices.

Sex Chromosome Pairing Mediated by Euchromatic Homology in Male Meiosis.

Diploid germline cells must undergo two consecutive meiotic divisions before differentiating as haploid sex cells. During meiosis I, homologs pair and remain conjoined until segregation at anaphase. spermatocytes are unique in that the canonical events of meiosis I including synaptonemal complex formation, double-strand DNA breaks, and chiasmata are absent.

Complete plastid genomes from Ophioglossum californicum, Psilotum nudum, and Equisetum hyemale reveal an ancestral land plant genome structure and resolve the position of Equisetales among monilophytes.

Background: Plastid genome structure and content is remarkably conserved in land plants. This widespread conservation has facilitated taxon-rich phylogenetic analyses that have resolved organismal relationships among many land plant groups. However, the relationships among major fern lineages, especially the placement of Equisetales, remain enigmatic.

Robustness of fat quantification using chemical shift imaging.

The purpose of this study was to investigate the effect of parameter changes that can potentially lead to unreliable measurements in fat quantification. Chemical shift imaging was performed using spoiled gradient echo sequences with systematic variations in the following: two-dimensional/three-dimensional sequence, number of echoes, delta echo time, fractional echo factor, slice thickness, repetition time, flip angle, bandwidth, matrix size, flow compensation and field strength. Results indicated no significant (or significant but small) changes in fat fraction with parameter.

Paternal, maternal, and biparental inheritance of the chloroplast genome in Passiflora (Passifloraceae): implications for phylogenetic studies.

Patterns of inheritance of the chloroplast genome in Passiflora were analyzed by examining the progeny from both interspecific and intraspecific crosses. Artificial crosses of field-collected material were performed in greenhouses at The University of Texas at Austin. DNA from fresh leaf material was analyzed by Southern blot techniques to identify the donor of the chloroplast genome.
