Summary Background Since 2006, many countries have implemented publicly funded human papillomavirus (HPV) immunisation programmes. However, global estimates of the extent and impact of vaccine ...coverage are still unavailable. We aimed to quantify worldwide cumulative coverage of publicly funded HPV immunisation programmes up to 2014, and the potential impact on future cervical cancer cases and deaths. Methods Between Nov 1 and Dec 22, 2014, we systematically reviewed PubMed, Scopus, and official websites to identify HPV immunisation programmes worldwide, and retrieved age-specific HPV vaccination coverage rates up to October, 2014. To estimate the coverage and number of vaccinated women, retrieved coverage rates were converted into birth-cohort-specific rates, with an imputation algorithm to impute missing data, and applied to global population estimates and cervical cancer projections by country and income level. Findings From June, 2006, to October, 2014, 64 countries nationally, four countries subnationally, and 12 overseas territories had implemented HPV immunisation programmes. An estimated 118 million women had been targeted through these programmes, but only 1% were from low-income or lower-middle-income countries. 47 million women (95% CI 39–55 million) received the full course of vaccine, representing a total population coverage of 1·4% (95% CI 1·1–1·6), and 59 million women (48–71 million) had received at least one dose, representing a total population coverage of 1·7% (1·4–2·1). In more developed regions, 33·6% (95% CI 25·9–41·7) of females aged 10–20 years received the full course of vaccine, compared with only 2·7% (1·8–3·6) of females in less developed regions. The impact of the vaccine will be higher in upper-middle-income countries (178 192 averted cases by age 75 years) than in high-income countries (165 033 averted cases), despite the lower number of vaccinated women (13·3 million vs 32·2 million). Interpretation Many women from high-income and upper-middle-income countries have been vaccinated against HPV. However, populations with the highest incidence and mortality of disease remain largely unprotected. Rapid roll-out of the vaccine in low-income and middle-income countries might be the only feasible way to narrow present inequalities in cervical cancer burden and prevention.

Research establishes the critical need to address the underrepresentation of women and racial/ethnic minorities in science, technology, engineering, and mathematics (STEM). While emergent research ...addresses similar challenges for sexual and gender minorities (SGM), this research remains scant and focuses on adult experiences. This analysis examines subgroup differences and the impact of bullying on STEM engagement outcomes among a national sample of SGM secondary students in the U.S.
This report provides descriptive and multivariable regression analysis of national survey data (n = 539) on the experiences of pre-college students who identify as SGM, including the effects of within-school anti-SGM bullying on STEM identity, perceptions of STEM climate, and STEM intentions.
Roughly 50% of the sample intended to enter a STEM field (compared to 25% in previous general samples). Bullying in school was negatively associated with STEM identity and perceptions of STEM climate. Sense of belonging is positively associated with perceptions of STEM climate and STEM intentions. Being non-binary and being a transgender man were associated with decreased sense of belonging and negative perception of STEM climate.
This report is the first to identify factors influencing STEM engagement among SGM secondary students and suggests that issues of STEM engagement are already present in adolescence. Moreover, the findings also establish the relationship between anti-SGM bullying and STEM outcomes highlighting the importance of this marginalization experience. Future research should further examine sub-group differences and the persistence of these effects. These findings highlight the need for research and intervention addressing STEM outcomes in SGM populations.

Dengue virus (DENV) is a public health challenge across the tropics and subtropics. Currently, there is no licensed prophylactic or antiviral treatment for dengue. The novel DENV inhibitor JNJ-1802 ...can significantly reduce viral load in mice and non-human primates. Here, using a mechanistic viral kinetic model calibrated against viral RNA data from experimental in-vitro infection studies, we assess the in-vitro inhibitory effect of JNJ-1802 by characterising infection dynamics of two DENV-2 strains in the absence and presence of different JNJ-1802 concentrations. Viral RNA suppression to below the limit of detection was achieved at concentrations of >1.6 nM, with a median concentration exhibiting 50% of maximal inhibitory effect (IC50) of 1.23x10-02 nM and 1.28x10-02 nM for the DENV-2/RL and DENV-2/16681 strains, respectively. This work provides important insight into the in-vitro inhibitory effect of JNJ-1802 and presents a first step towards a modelling framework to support characterization of viral kinetics and drug effect across different host systems.
This evidence-based clinical practice guideline is a revision of the 2004 acute otitis media (AOM) guideline from the American Academy of Pediatrics (AAP) and American Academy of Family Physicians. ...It provides recommendations to primary care clinicians for the management of children from 6 months through 12 years of age with uncomplicated AOM. In 2009, the AAP convened a committee composed of primary care physicians and experts in the fields of pediatrics, family practice, otolaryngology, epidemiology, infectious disease, emergency medicine, and guideline methodology. The subcommittee partnered with the Agency for Healthcare Research and Quality and the Southern California Evidence-Based Practice Center to develop a comprehensive review of the new literature related to AOM since the initial evidence report of 2000. The resulting evidence report and other sources of data were used to formulate the practice guideline recommendations. The focus of this practice guideline is the appropriate diagnosis and initial treatment of a child presenting with AOM. The guideline provides a specific, stringent definition of AOM. It addresses pain management, initial observation versus antibiotic treatment, appropriate choices of antibiotic agents, and preventive measures. It also addresses recurrent AOM, which was not included in the 2004 guideline. Decisions were made on the basis of a systematic grading of the quality of evidence and benefit-harm relationships. The practice guideline underwent comprehensive peer review before formal approval by the AAP. This clinical practice guideline is not intended as a sole source of guidance in the management of children with AOM. Rather, it is intended to assist primary care clinicians by providing a framework for clinical decision-making. It is not intended to replace clinical judgment or establish a protocol for all children with this condition. These recommendations may not provide the only appropriate approach to the management of this problem.
Little remains known about both Asian and Asian American (A/AA) and non-Asian young adults' experiences and affective reactions regarding COVID-19 anti-Asian discrimination. To our knowledge, this is ...the first study that explores the nature and impact of COVID-19 anti-Asian discrimination within a multi-racial sample.
This study uses qualitative open-ended responses from a sub-sample of Wave I of the COVID-19 Adult Resilience Experiences Study (CARES) data collected between March to September 2020. Thematic analysis was used to explore two open-ended questions: "Are there experiences we missed in the survey so far that you wish to describe?" and "What are your thoughts about the current social climate?" The data analysis for this study focused on 113 discrimination or racism-related comments.
A total of 1331 young adults completed an online survey of which 611 provided comments; a multi-racial sample of 95 individuals (65.3% non-Asians, 24.7% A/AA) contributed 113 COVID-19 anti-Asian discrimination or racism-related comments. Two overarching themes were: types of discrimination (societal, interpersonal, intrapersonal) and affective reactions to discrimination (fear, anxiety/distress, hopelessness/depression, and avoidance). Not only did both A/AA and non-Asian participants report witnessing or hearing reports of anti-Asian discrimination, but both groups described having negative affective reactions to anti-Asian discrimination.
Anti-Asian discrimination in the face of COVID may be more widespread than initial reports indicate. Our finding suggests that anti-Asian discrimination is a societal illness that impacts all populations in the U.S. This calls for cross-racial coalitions and solidarity in the fight against discrimination and racism.
Delivery and use of HIV pre-exposure prophylaxis (PrEP) are suboptimal in the United States. Previous reviews of barriers and facilitators have not used an implementation science lens, limiting ...comprehensiveness and the link to implementation strategies. To summarize the state of the science, we systematically reviewed determinants of PrEP implementation using the updated Consolidated Framework for Implementation Research (CFIR 2.0).
PrEP-eligible communities and delivery settings in the United States.
In January 2021, we searched Ovid MEDLINE, PsycINFO, and Web of Science for peer-reviewed articles related to HIV/AIDS, interventions, implementation, and determinants or strategies. We identified 286 primary research articles published after 1999 about US-based PrEP implementation. Team members extracted discrete "mentioned" and "measured" determinants, coding each by setting, population, valence, measurement, and CFIR 2.0 construct.
We identified 1776 mentioned and 1952 measured determinants from 254 to 239 articles, respectively. Two-thirds of measured determinants were of PrEP use by patients as opposed to delivery by providers. Articles contained few determinants in the inner setting or process domains (ie, related to the delivery context), even among studies of specific settings. Determinants across priority populations also focused on individual patients and providers rather than structural or logistical factors.
Our findings suggest substantial knowledge in the literature about general patient-level barriers to PrEP use and thus limited need for additional universal studies. Instead, future research should prioritize identifying determinants, especially facilitators, unique to understudied populations and focus on structural and logistical features within current and promising settings (eg, pharmacies) that support integration of PrEP into clinical practice.
Childhood sexual abuse (CSA) is associated with a wide range of health outcomes and is more prevalent among men who have sex with men (MSM) compared to men who have sex with women exclusively and ...among transgender women (TW) compared to cisgender peers; however, there is a lack of consensus regarding an explanatory theoretical model. This analysis examined these models across health outcomes using baseline data from a longitudinal study of MSM and TW in Chicago (n = 1,035) collected from 2015 to 2019. Severity of CSA was measured for two age ranges (prior to 13 and 13-17). Logistic regression and negative binomial regressions were estimated. Teenage experiences of CSA were associated with alcohol problems, cannabis problems, suicide ideation/attempt, depression, condomless anal sex partners, rectal STI, and HIV. Pre-teenage CSA was associated with alcohol use and depressive symptoms. Significant interactions across age of experience of CSA were found for alcohol problems, cannabis problems, and condomless anal sex partners. Consistent with previous literature, this analysis found CSA to be a significant influence on various health outcomes. No single explanatory framework emerged; however, adolescent exposures may be more closely linked to health outcomes and risk behaviors than pre-teenage or cumulative exposures.
Bisexual and other non-monosexual (bi+) people are at increased risk for depression and anxiety compared to both heterosexual and gay/lesbian people. Bi + people are also more likely to conceal their ...sexual orientation than gay/lesbian people are, and concealment is generally associated with negative mental health outcomes. Despite evidence that concealment is a particularly salient stressor for bi+ people, there has been a lack of attention to their motivations for concealment. As such, the goal of the current study was to examine the associations among concealment, motivations for concealment, and depression and generalized anxiety symptoms in a sample of 715 bi+ people who completed an online survey. Nearly half of participants endorsed purposely trying to conceal their bi+ identity in their day-to-day life, and concealment was significantly associated with higher levels of depression and generalized anxiety. Using exploratory factor analysis, we identified two motivations for concealment: intrapersonal motivations (e.g., one's bi+ identity not being a central part of one's overall identity, not being comfortable with being bi+) and interpersonal motivations (e.g., concern about being judged or treated negatively, concern about putting oneself at risk of physical harm). Interpersonal motivations were significantly associated with higher levels of depression and generalized anxiety, whereas intrapersonal motivations were not. In sum, while concealment may generally be associated with negative mental health outcomes, this may only be the case for those who conceal out of concern for discrimination and victimization. These findings highlight the importance of examining bi+ people's motivations for concealing their sexual orientation in order to understand the extent to which they experience negative mental health outcomes.
In this paper, we build a new test of rational expectations based on the marginal distributions of realizations and subjective beliefs. This test is widely applicable, including in the common ...situation where realizations and beliefs are observed in two different data sets that cannot be matched. We show that whether one can rationalize rational expectations is equivalent to the distribution of realizations being a mean-preserving spread of the distribution of beliefs. The null hypothesis can then be rewritten as a system of many moment inequality and equality constraints, for which tests have been recently developed in the literature. The test is robust to measurement errors under some restrictions and can be extended to account for aggregate shocks. Finally, we apply our methodology to test for rational expectations about future earnings. While individuals tend to be right on average about their future earnings, our test strongly rejects rational expectations.
Intimate partner violence (IPV) is associated with adverse mental and physical outcomes among men who have sex with men (MSM) living with HIV. Few studies focus on psychological IPV, such as verbal ...threats. This study examined the associations between different forms of IPV and depression and CD4+ cell count, with depression as a mediator for the association between IPV and CD4+ cell count. Data for these analyses were derived from a larger cross-sectional study on HIV-HCV co-infection among MSM in Shanghai, China (N = 1623). We estimated the average causal mediation effects (ACME) and average direct effects (ADE) through three steps. About 16% of participants experienced IPV, with forced sex (7%), verbal threats (5%), and thrown objects (4%) being most common. Verbal threats showed the strongest link with depression and low CD4+ cell count. Depression fully mediated the relationship between verbal abuse and low CD4+ cell count, suggesting it as a potential pathway between psychological IPV and poorer HIV-related health outcomes. More research on psychological IPV is warranted to examine its health impacts. Mental health could be a potential focus of intervention to enhance HIV-related health outcomes among MSM with IPV experience.
