Levels of knowledge about the sexual transmission of Zika virus are consistently low in populations at risk of a mosquito-borne outbreak, including among women of childbearing age and women who are pregnant or intend to become pregnant. We investigated the effectiveness of sources of public health messaging about sexual transmission to women who are pregnant or intend to become pregnant in Arizona.

In 2017, we conducted an Arizona-statewide survey 15 months after the initial release of US guidelines on sexual transmission of Zika virus. We used Poisson regression, adjusting for demographic factors, to estimate the likelihood among women who were pregnant or intended to become pregnant of knowing that Zika virus is sexually transmitted relative to other women of childbearing age. We used multinomial logistic regression models to explore associations with most used health information sources, either in person (eg, medical providers) or online (eg, Facebook), categorized by extent of dependability.

Women wransmission, even though it was available. To prepare for possible future outbreaks, research should explore which aspects of Zika information campaigns were ineffective or inefficient.Introduction Trastuzumab deruxtecan (T-DXd) is a novel human epidermal growth factor receptor 2 (HER2)-targeted antibody-drug conjugate with a humanized anti-HER2 antibody, cleavable peptide-based linker, and topoisomerase I inhibitor payload. The phase II trial DESTINY-Gastric01 has demonstrated that T-DXd exhibits antitumor activity in patients with HER2-positive advanced gastric cancer (AGC) who had received at least two previous therapies, including trastuzumab.Area covered T-DXd was approved for previously treated HER2-positive AGC in Japan. The US Food and Drug Administration also approved on 15 January 2021. In this article, we review the development of T-DXd, its pharmacology, and its safety profile in patients with HER2-positive AGC.Expert opinion T-DXd has demonstrated a significantly higher objective response rate and a longer overall survival in HER2-positive AGC patients with two or more previous lines of systemic chemotherapy, including trastuzumab. Safety profile was acceptable. Currently, there are several ongoing clinical trials of T-DXd in combination with cytotoxic chemotherapy or an immune checkpoint inhibitor.Introduction Fanconi anemia (FA) is a rare congenital disease that belongs to the family of congenital trilinear bone marrow failure. Most FA patients will suffer bone marrow failure and the main treatment relies on supportive measures or more recently on the use of hematopoietic stem cell transplant. The improvements seen in the management of FA has led women to reach childbearing age and have successful pregnancies. However, these pregnancies are associated with increased complications such as preterm delivery, cesarean delivery, eclampsia and others.Areas covered This review highlights on the outcome of pregnancies in FA patients reported in the literature along with practical recommendations.Expert opinion Multidisciplinary efforts are required to optimize the management of pregnancy in FA patients. Moreover, the development of a set of recommendations to optimize the treatment is highly necessary.Life is pervasive on planet Earth, but whether life is ubiquitous in the Galaxy and sustainable over timescales comparable to stellar evolution is unknown. Evidence suggests that life first appeared on Earth more than 3.77 Gyr ago, during a period of heavy meteoric bombardment. Amino acids, the building blocks of proteins, have been demonstrated to exist in interstellar ice. As such, the contribution of space-generated amino acids to those existing on Earth should be considered. However, detection of space amino acids is challenging. In this study, we used analytical data from several meteorites and in situ measurements of the comet 67P/Churyumov-Gerasimenko collected by the Rosetta probe to evaluate the detectability of alanine by ultraviolet spectropolarimetry. Alanine is the second-most abundant amino acid after glycine and is optically active. This chirality produces a unique signature that enables reliable identification of this amino acid using the imprint of optical rotatory dispersion (ORD) and circular dichroism (CD) in the ultraviolet spectrum (130-230 nm). Here, we show that the ORD signature could be detected in comets by using ultraviolet spectropolarimetric observations conducted at middle size space observatories. These observations can also provide crucial information for the study of sources of enantiomeric imbalance on Earth.The search for possible biosignature gases in habitable exoplanet atmospheres is accelerating, although actual observations are likely years away. This work adds isoprene, C5H8, to the roster of biosignature gases. We found that isoprene geochemical formation is highly thermodynamically disfavored and has no known abiotic false positives. The isoprene production rate on Earth rivals that of methane (CH4; ∼500 Tg/year). Unlike methane, on Earth isoprene is rapidly destroyed by oxygen-containing radicals. Although isoprene is predominantly produced by deciduous trees, isoprene production is ubiquitous to a diverse array of evolutionary distant organisms, from bacteria to plants and animals-few, if any, volatile secondary metabolites have a larger evolutionary reach. Although non-photochemical sinks of isoprene may exist, such as degradation of isoprene by life or other high deposition rates, destruction of isoprene in an anoxic atmosphere is mainly driven by photochemistry. Motivated by the concept that isoprenrene substructure. Despite these challenges, isoprene is worth adding to the menu of potential biosignature gases.This corrects the article DOI 10.1103/PhysRevLett.126.031102.This corrects the article DOI 10.1103/PhysRevLett.125.258002.This corrects the article DOI 10.1103/PhysRevLett.119.127204.The existence of an ideal glass and the resolution to the Kauzmann paradox is a long-standing open question in materials science. To address this problem, we exploit the ability of glasses with large interfacial area to access low energy states. check details We submit aggregates of spheres of a polymeric glass former to aging well below their glass transition temperature, T_g; and characterize their thermodynamic state by calorimetry, and the vibrational density of state (VDOS) by inelastic neutron scattering (INS). We show that, when aged at appropriate temperatures, glassy spheres attain a thermodynamic state corresponding to an ideal glass in time scales of about one day. In this state, the boson peak, underlying the deviation from the Debye level of the VDOS, is essentially suppressed. Our results are discussed in the framework of the link between the macroscopic thermodynamic state of glasses and their vibrational properties.
