With the development of multiple effective vaccines, reducing the global morbidity and mortality of COVID-19 will depend on the distribution and acceptance of COVID-19 vaccination. Estimates of global vaccine acceptance among pregnant women and mothers of young children are yet unknown. An understanding of the challenges and correlates to vaccine acceptance will aid the acceleration of vaccine administration within these populations. Acceptance of COVID-19 vaccination among pregnant women and mothers of children younger than 18-years-old, as well as potential predictors, were assessed through an online survey, administered by Pregistry between October 28 and November 18, 2020. 17,871 total survey responses from 16 countries were obtained. Given a 90% COVID-19 vaccine efficacy, 52.0% of pregnant women (n = 2747/5282) and 73.4% of non-pregnant women (n = 9214/12,562) indicated an intention to receive the vaccine. 69.2% of women (n = 11,800/17,054), both pregnant and non-pregnant, indicated an intention to vaccinate their children. Vaccine acceptance was generally highest in India, the Philippines, and all sampled countries in Latin America; it was lowest in Russia, the United States and Australia. The strongest predictors of vaccine acceptance included confidence in vaccine safety or effectiveness, worrying about COVID-19, belief in the importance of vaccines to their own country, compliance to mask guidelines, trust of public health agencies/health science, as well as attitudes towards routine vaccines. COVID-19 vaccine acceptance and its predictors among women vary globally. Vaccination campaigns for women and children should be specific for each country in order to attain the largest impact.

The association of previous advanced immunosuppression with prevalent and sustained impairment suggests that there is a non-reversible component of neural injury that tracks with a history of disease progression. The association of sustained impairment with worse current immune status (low CD4 cell count) suggests that restoring immunocompetence increases the likelihood of neurocognitive recovery. Finally, the lack of association between incident neurocognitive impairment and virological and immunological indicators implies that neural injury continues in some patients regardless of the success of antiretroviral therapy on these laboratory measures.

In the early months of the COVID-19 epidemic, some have wondered if the force of this global experience will solve the problem of vaccine refusal that has vexed and preoccupied the global public health community for the last several decades. Drawing on historical and epidemiological analyses, we critique contemporary approaches to reducing vaccine hesitancy and articulate our notion of vaccine confidence as an expanded way of conceptualizing the problem and how to respond to it. Intervening on the rush of vaccine optimism we see pervading present discourse around the COVID-19 epidemic, we call for a re-imagination of the culture of public health and the meaning of vaccine safety regulations. Public confidence in vaccination programs depends on the work they do for the community-social, political, and moral as well as biological. The concept of public health and its programs must be broader than the delivery of the vaccine technology itself. The narrative work and policy actions entailed in actualizing such changes will, we expect, be essential in achieving a true vaccine confidence, however the public reacts to the specific vaccine that may be developed for COVID-19.

Immune function was observed for 144 weeks in 643 human immunodeficiency virus (HIV)-infected subjects who (1) had nadir CD4+ cell counts of <50 cells/mm3, followed by a sustained increase to > or =100 cells/mm3 after the initiation of HAART, and (2) were enrolled in a randomized trial of continued azithromycin prophylaxis versus withdrawal for prevention of Mycobacterium avium complex disease. The median CD4+ cell count was 226 cells/mm3 at entry and 358 cells/mm3 at week 144. Anergy (80.2% of patients) and lack of lymphoproliferative response to tetanus toxoid (TT; 73%) after immunization and impaired antibody responses after receipt of hepatitis A (54%) and TT (86%) vaccines were considered to be evidence of impaired immune reconstitution. Receipt of azithromycin did not have an effect on CD4+ cell count but was associated with higher rates of delayed-type hypersensitivity responses to TT (25% of subjects who received azithromycin vs. 15% of those who did not; P=.009) and mumps skin test antigen (29% vs. 17%; P=.001). Although the subjects had only partial responses to immune function testing, the rate of opportunistic infections was very low, and none of the tests was predictive of risk.

This laboratory recently identified a novel proton-coupled folate transporter (PCFT) that mediates intestinal folate absorption and transport of folates into the central nervous system. The present study focuses on the definition of the minimum transcriptional regulatory region of this gene in HeLa cells and the mechanism(s) underlying the loss of PCFT expression in the methotrexate-resistant HeLa R1-11 cell line. The PCFT transcriptional regulatory controls were localized between −42 and +96 bases from the transcriptional start site using a luciferase-reporter gene system.

The surge in Peer to Peer e-commerce has increasingly been characterized by changing the online marketplace to a more personalized environment for the buyer and seller. This personalization involves revealing information on buyer reviews, pictures and biographical information on the sellers to reduce the perceived "purchase risk" or to facilitate trust with the buyers. However, this personalization has generated possibilities for discrimination in the online marketplace. In this paper, we examine the effect of host information available online (race, gender and sexual orientation etc.) on price listings on Airbnb.com in San Francisco. We find that Hispanic hosts and Asian hosts, on average, have a 9.6% and 9.3% lower list price relative to their White counterparts, after controlling for neighborhood property values, user reviews and rental unit characteristics. We don't find any significant impact of gender and sexual orientation on price listings. Overall, our findings corroborate the presence of racial discrimination in the online marketplace.

Most advanced AIDS patients responding to HAART for prolonged periods have stable or improving cognition, but remain more likely to be impaired than the general population. During HAART, improving test performance probably reflects both practice effects and continuing neurological recovery after more than 3 years of HAART.
