RESUMO
BACKGROUND: Gay and bisexual men (GBM) who use HIV preexposure prophylaxis (HIV-PrEP) have high rates of bacterial sexually transmitted infections (STIs). The use of daily antibiotics as STI preexposure prophylaxis (STI-PrEP) may be appealing to GBM who are using or have previously used HIV-PrEP (HIV-PrEP-experienced) for the prevention of bacterial STIs. METHODS: We examined willingness to use daily STI-PrEP among a cross-sectional sample of HIV-PrEP-experienced GBM in Australia who participated in an observational online cohort study from August 2018 to March 2020. Factors associated with willingness to use daily STI-PrEP were determined using bivariate and multivariate logistic regression. RESULTS: Of the 1347 participants, half (54.3%) were willing to use daily STI-PrEP. Factors independently associated with greater willingness to use daily STI-PrEP included having >10 sexual partners in the last 6 months, using methamphetamine in the last 6 months, being more conscious about avoiding STIs, having a greater number of STIs since commencing HIV-PrEP, being willing to take HIV-PrEP for as long as they were at risk of acquiring HIV, and only using condoms when a sexual partner requested them. Conversely, factors associated with less willingness to use daily STI-PrEP included being university educated, using nondaily dosing regimens of HIV-PrEP, preferring event-driven HIV-PrEP, and being concerned about long-term HIV-PrEP adverse effects. CONCLUSIONS: Sexually transmitted infection PrEP is likely to be appealing to many HIV-PrEP-experienced GBM, especially those who engage in activities associated with a higher risk of STI transmission. However, they are less likely to be willing to use STI-PrEP unless it aligns with their HIV-PrEP dosing regimen, suggesting that research into the safety and efficacy of alternative STI prophylaxis dosing options should be prioritized.

BACKGROUND: Gay, bisexual, and other men who have sex with men (GBM) are overrepresented in diagnoses of sexually transmitted infections (STIs) relative to their population size. This study assessed trends in STI testing and diagnoses among GBM in Australia. METHODS: The Gay Community Periodic Surveys are repeated cross-sectional behavioral surveillance surveys of GBM. Participants reported the number of anal swabs, throat swabs, urine samples, and blood tests for syphilis they undertook in the last year. "Frequent comprehensive testing" was defined as ≥3 of each test in the previous year. Participants reported STI diagnoses of chlamydia, gonorrhea, syphilis, and other STIs in the last year. Trends in testing and diagnoses from 2017 to 2020 and 2020 to 2021 were assessed with logistic regression models. RESULTS: We analyzed 24,488 survey responses from participants reporting casual sex in the last 6 months. Between 2017 and 2020, frequent comprehensive STI testing decreased among HIV-negative GBM on preexposure prophylaxis (PrEP) from 71.7% to 68.9% and declined further to 58.6% in 2021. Frequent comprehensive STI testing was stable during 2017-2020 among HIV-negative/untested GBM not on PrEP (17.4%-14.6%) and HIV-positive GBM (30.4%-35.1%) but declined in 2021 to 7.5% among non-PrEP-users and 25.7% among HIV-positive participants. There were minimal changes in STI diagnoses during 2017-2020, but diagnoses declined in 2021. CONCLUSIONS: Many GBM do not meet Australian STI testing guidelines that recommend quarterly testing. Further evaluation of whether this recommendation is realistic or necessary to reduce STIs among GBM is recommended.

COVID-19 has disrupted sexual behaviour and access to health systems. We adapted regular HIV behavioural surveillance of gay and bisexual men (GBM) in Australia in response to COVID-19, assessed the impact on the profile of the sample, the participants' HIV-related behaviour, and whether COVID-19 may have accentuated existing disparities in the Australian HIV epidemic. Data collected from five states during July 2017-June 2021 were included (N = 31,460). The emphasis on online recruitment after COVID-19 led to smaller sample sizes, greater geographic reach, and a higher proportion of bisexual-identifying participants. Most participants (88.1%) reported physical distancing and 52.1% had fewer sex partners due to COVID-19. In the COVID-19-affected rounds (July 2020-June 2021), the number of male partners, recent HIV testing and pre-exposure prophylaxis (PrEP) use all fell, and HIV risk among the smaller group of participants who reported casual sex increased. COVID-related changes were generally more pronounced among GBM aged under 25 years, participants from suburbs with fewer gay residents, and bisexual men. These groups should be prioritised when encouraging GBM to reengage with HIV testing services and effective prevention methods, like condoms and PrEP.
RESUMEN: COVID-19 ha interrumpido el comportamiento sexual y el acceso a los sistemas de salud. Adaptamos la vigilancia regular del comportamiento de hombres homosexuales y bisexuales (GBM) hacia el VIH en Australia en respuesta a COVID-19, evaluamos el impacto en el perfil de la muestra, el comportamiento relacionado con el VIH de los participantes y si COVID-19 puede haber acentuado las existentes disparidades en la epidemia australiana de VIH. Se incluyeron los datos recopilados de cinco estados entre julio de 2017 y junio de 2021 (N = 31 460). El énfasis en el reclutamiento en línea después de COVID-19 resulto en tamaños de muestra más pequeños, mayor alcance geográfico y una mayor proporción de participantes que se identifican como bisexuales. La mayoría de los participantes (88,1%) describieron participando en el distanciamiento físico y el 52,1% tuvo menos parejas sexuales debido a la COVID-19. En las rondas afectadas por COVID-19 (julio de 2020 a junio de 2021), disminuyó la cantidad de parejas masculinas, el uso reciente de pruebas de VIH y de la profilaxis previa a la exposición (PrEP), y el riesgo de VIH entre el grupo más pequeño de participantes que participaron en sexo casual aumentó. Los cambios relacionados con COVID fueron generalmente más pronunciados entre GBM menores de 25 años, participantes de suburbios con menos residentes homosexuales y hombres bisexuales. Se debe priorizar a estos grupos al alentar a GBM a volver a comprometerse con los servicios de pruebas de VIH y métodos de prevención efectivos, como condones y PrEP.

We mapped gay and bisexual men's (GBM) patterns of using pre-exposure prophylaxis (PrEP) over time and explored sexual behavior as PrEP use changed. We conducted semi-structured interviews between June 2020 and February 2021 with 40 GBM living in Australia who had changed their PrEP use since initiating. There was considerable diversity in patterns of discontinuation, suspension, and recommencement of PrEP. Reasons for changing PrEP use mostly centered on accurate perceived changes to HIV risk. Twelve participants reported condomless anal intercourse with casual or fuckbuddy partners after discontinuing PrEP. These sex events were unanticipated, condoms were not a preferred option, and other risk reduction strategies were applied inconsistently. Service delivery and health promotion can support safer sex among GBM when PrEP use fluctuates by promoting event-driven PrEP and/or non-condom-based risk reduction methods during periods off daily PrEP, and guiding GBM to better recognize changing circumstances of risk and when to recommence PrEP.

The introduction of HIV pre-exposure prophylaxis (PrEP) has the potential to impact the attitudes gay and bisexual men (GBM) who consequently choose to take PrEP have towards treatment as prevention (TasP), and the extent to which they are willing to have condomless anal intercourse (CLAI) with an HIV-positive sexual partner who has an undetectable viral load (UVL). Using a cross-sectional sample from an observational cohort study conducted from August 2018 to March 2020, we examined the extent to which PrEP-experienced GBM are willing to have CLAI with a partner who has a UVL. Simple and multiple logistic regression models were used to identify associated variables. Of the 1386 participants included in the analyses, 79.0% believed in the effectiveness of TasP, and 55.3% were willing to have CLAI with a partner who has a UVL. Wiling participants were less worried about getting HIV when taking PrEP and more likely to believe in TasP. Further research is needed to better understand the gap between belief in TasP and willingness to have CLAI with a partner who has a UVL among PrEP-experienced GBM.

Using repeated behavioural surveillance data collected from gay and bisexual men (GBM) across Australia, we assessed trends in HIV prevention coverage (the level of 'safe sex' achieved in the population by the use of effective prevention methods, including condoms, pre-exposure prophylaxis [PrEP] and having an undetectable viral load). We stratified these trends by age, country of birth/recency of arrival, sexual identity, and the proportion of gay residents in the participant's suburb. Among 25,865 participants with casual male partners, HIV prevention coverage increased from 69.8% in 2017 to 75.2% in 2021, lower than the UNAIDS target of 95%. Higher levels of coverage were achieved among older GBM (≥ 45 years), non-recently-arrived migrants, and in suburbs with ≥ 10% gay residents. The lowest levels of prevention coverage (and highest levels of HIV risk) were recorded among younger GBM (< 25 years) and bisexual and other-identified participants. Younger, recently-arrived, and bisexual GBM were the most likely to use condoms, while PrEP use was concentrated among gay men, 25-44-year-olds, and in suburbs with more gay residents. The use of undetectable viral load was most common among participants aged ≥ 45 years. Our analysis shows that high HIV prevention coverage can be achieved through a mixture of condom use, PrEP use, and undetectable viral load, or by emphasising PrEP use. In the Australian context, younger, bisexual and other-identified GBM should be prioritised for enhanced access to effective HIV prevention methods. We encourage other jurisdictions to assess the level of coverage achieved by combination prevention, and variations in uptake.
RESUMEN: Utilizando datos repetidos de vigilancia conductual recopilados de hombres homosexuales y bisexuales (GBM) en toda Australia, evaluamos las tendencias en la cobertura de la prevención del VIH (el nivel de "sexo seguro" logrado en la población mediante el uso de métodos de prevención eficaces, incluyendo condones, Profilaxis de Pre-Exposición al VIH [PrEP] y tener una carga viral indetectable). Estratificamos estas tendencias por edad, país de nacimiento/tiempo desde la llegada al país, identidad sexual y proporción de residentes homosexuales en el suburbio del participante. Entre 25.865 participantes con parejas masculinas ocasionales, la cobertura de prevención del VIH aumentó del 69,8% en 2017 al 75,2% en 2021, cifra inferior al objetivo de ONUSIDA del 95%. Se lograron niveles más altos de cobertura entre GBM de mayor edad (≥45 años), inmigrantes no llegados recientemente y en suburbios con ≥10% de residentes homosexuales. Los niveles más bajos de cobertura de prevención (y los niveles más altos de riesgo de VIH) se registraron entre los GBM más jóvenes (<25 años) y los participantes bisexuales y con otras identidades. Los GBM más jóvenes, recién llegados y bisexuales fueron los más propensos a usar condones, mientras que el uso de PrEP se concentró entre hombres homosexuales, de 25 a 44 años, y en los suburbios con más residentes homosexuales. El uso de carga viral indetectable fue más común entre los participantes de ≥45 años. Nuestro análisis demuestra que se puede lograr una alta cobertura de prevención del VIH mediante una combinación del uso de condón, uso de PrEP y carga viral indetectable, o enfatizando el uso de PrEP. En el contexto australiano, se debe dar prioridad a los GBM más jóvenes, bisexuales y con otras identidades para mejorar el acceso a métodos eficaces de prevención del VIH. Alentamos a otras jurisdicciones a evaluar el nivel de cobertura logrado mediante la prevención combinada y las variaciones en la adopción.
RESUMO
HIV self-testing allows people to collect samples and test themselves at home, addressing known barriers to facility-based testing. We aimed to measure the uptake of home HIV testing among Australian gay and bisexual men (GBM). Using national cross-sectional data from the Australian Gay Community Periodic Surveys, we assessed trends in home HIV testing among non-HIV positive GBM between 2018 and 2020. Overall, the use of home HIV testing was low, but slightly increased during 2018-2020 (from 0.3 to 0.8%, RR = 1.54, 95%CI = 1.23-1.92, p-trend < 0.001). Testing at home was more likely among non-HIV-positive GBM who were born overseas and recently arrived in Australia, at higher risk of HIV, and infrequent HIV testers. Given the greater use of home testing by men at higher risk of HIV, recent migrants and infrequent testers, all priority groups in Australia's HIV epidemic, we recommend increasing access to HIV self-testing to enhance uptake in these and other groups of GBM.

BACKGROUND: Asian gay, bisexual, and other men who have sex with men (GBMSM) are overrepresented in new HIV diagnoses in Australia. Social engagement with other GBMSM has been associated with HIV testing and pre-exposure prophylaxis (PrEP) uptake. Asian GBMSM may be socially disconnected from LGBTQ+ people, which may increase their HIV risk. This analysis assessed the contribution of social connection on HIV risk among Asian GBMSM. METHODS: Using an online cross-sectional survey of Asian GBMSM in Australia, we measured condomless anal intercourse (CLAI) in the last 6months without PrEP or an undetectable viral load (UVL), i.e. CLAI with a risk of HIV transmission. Bivariable and multivariable logistic regression models were performed to compare demographic characteristics and social engagement of participants who had CLAI without PrEP or UVL to those who had not. Analyses were restricted to participants who reported sex with casual partners in the last 6months. RESULTS: Among 509 participants who had casual partners in the last 6months, 151 (29.7%) reported CLAI without PrEP or UVL. CLAI without PrEP or UVL was negatively associated with full-time employment, and recently being tested for HIV and was positively associated with experiencing discrimination based on sexual orientation. Social engagement with LGBTQ+ people was not associated with CLAI without PrEP or UVL. CONCLUSIONS: CLAI without PrEP or UVL was not related to social connections with LGBTQ+ people but was more likely among Asian men who had experienced sexuality-related discrimination, suggesting that mitigating homophobia and biphobia may assist in improving HIV prevention among Asian GBMSM who live in Australia.

Before emergence in late 2021 of the highly transmissible B.1.1.529 (Omicron) variant of SARS-CoV-2, the virus that causes COVID-19 (1,2), several studies demonstrated that SARS-CoV-2 was unlikely to be cultured from specimens with high cycle threshold (Ct) values§ from real-time reverse transcription-polymerase chain reaction (RT-PCR) tests (suggesting low viral RNA levels) (3). Although CDC and others do not recommend attempting to correlate Ct values with the amount of infectious virus in the original specimen (4,5), low Ct values are sometimes used as surrogate markers for infectiousness in clinical, public health, or research settings without access to virus culture (5). However, the consistency in reliability of this practice across SARS-CoV-2 variants remains uncertain because Omicron-specific data on infectious virus shedding, including its relationship with RNA levels, are limited. In the current analysis, nasal specimens collected from an ongoing longitudinal cohort¶ (6,7) of nonhospitalized participants with positive SARS-CoV-2 test results living in the San Francisco Bay Area** were used to generate Ct values and assess for the presence of culturable SARS-CoV-2 virus; findings were compared between specimens from participants infected with pre-Omicron variants and those infected with the Omicron BA.1 sublineage. Among specimens with culturable virus detected, Ct values were higher (suggesting lower RNA levels) during Omicron BA.1 infections than during pre-Omicron infections, suggesting variant-specific differences in viral dynamics. Supporting CDC guidance, these data show that Ct values likely do not provide a consistent proxy for infectiousness across SARS-CoV-2 variants.

Alternatives to daily dosing of HIV pre-exposure prophylaxis (PrEP) are continuing to emerge. From October 2019 to March 2020, we conducted an online survey of PrEP-experienced gay and bisexual men in Australia about interest in and preference for four different PrEP modalities: daily dosing, event-driven dosing, long-acting injectable (LAI)-PrEP and subdermal PrEP implants. Using data from 1477 participants, we measured interest and preference of different modalities using multivariate logistic regression. High proportions of participants were interested in LAI-PrEP (59.7%), daily PrEP (52.0%), PrEP implants (45.3%) and event-driven PrEP (42.8%). LAI-PrEP was the most frequently selected preference (30.5%), followed by PrEP implants (26.3%), daily PrEP (21.4%) and event-driven PrEP (21.2%). Higher interest and preference for non-daily PrEP modalities were associated with being concerned about side effects and perceived difficulties with daily adherence. As novel modalities emerge, attitudes to them should be considered in public health messaging to facilitate informed decision-making.

Changes to how gay, bisexual, and other men who have sex with men (GBM) connect with each other and with their communities have implications for HIV prevention. Social engagement with gay men (defined as having friends who are gay men and spending time with them) has been associated with HIV related outcomes over time among Australian GBM. Using data collected in national, repeated, cross-sectional surveys of GBM between 1998 and 2020 (N = 161,117), analyses of trends in the prevalence of gay social engagement (GSE) in Australia were conducted using linear regression. To assess changing associations with GSE at different time points in the HIV epidemic, three cross-sectional analyses were conducted on factors associated with high and low GSE in 1999/2000, 2009/2010, and 2019/2020 using bivariate and multivariable logistic regression. GSE (scored from 0 to 7) declined among all participants from 4.76 in 1998 to 4.04 in 2020 (p < 0.001) with a steeper decline among GBM aged under 25 years from 4.63 in 1998 to 3.40 in 2020 (p < 0.001). In all timepoints, high GSE was associated with older age, being university educated, full time employment, identifying as gay, recent HIV testing, and PrEP uptake. While mostly associated with protective behaviors, high GSE was also associated with some practices that may put GBM at risk of HIV infection such as drug-enhanced sex and group sex in the most recent timepoint. Changing levels of GSE have implications for health promotion among GBM, particularly how to engage GBM less connected to gay social networks.

We examined depression and anxiety prior to and during COVID-19 restrictions in Australian gay and bisexual men (GBM). In an online cohort, a COVID-19-focused survey was conducted in April 2020. During 2019 and in April 2020, 664 GBM completed the Patient Health Questionnaire (PHQ-9, measuring depression) and Generalized Anxiety Disorder Assessment (GAD-7, measuring anxiety). Increased depression and anxiety were defined as a ≥ 5 point increase on the respective scales. Mean PHQ-9 and GAD-7 scores increased between 2019 and 2020 (PHQ-9: from 5.11 in 2019 to 6.55 in 2020; GAD-7: from 3.80 in 2019 to 4.95 in 2020). The proportion of participants with moderate-severe depression (PHQ-9 ≥ 10) increased from 18.8% (n = 125) to 25.5% (n = 169), while the proportion of participants with moderate-severe anxiety (GAD-7 ≥ 10) increased from 12.7% (n = 84) to 17.3% (n = 115). Almost one-quarter of participants (n = 158, 23.8%) had increased depression; in these men, mean PHQ-9 increased from 2.49 in 2019 to 11.65 in 2020 (p < 0.001). One-in-five (20.6%) participants (n = 137) had increased anxiety; among these men, mean GAD-7 increased from 2.05 in 2019 to 10.22 in 2020 (p < 0.001). Increases were associated with concerns about job security, reduction in social and sexual connections and opportunities, and being personally concerned about COVID-19 itself. COVID-19 appeared to have a sudden and pronounced impact on depression and anxiety in Australian GBM, with a significant minority showing sharp increases. Ongoing monitoring is required to determine longer-term impacts and GBM need access to appropriate and sensitive supports both during and after the COVID-19 pandemic.

BACKGROUND: Recent changes to Australian PrEP prescribing guidelines support the use of event-driven pre-exposure prophylaxis (ED-PrEP) to prevent HIV among gay and bisexual men (GBM). Social marketing campaigns to increase awareness of ED-PrEP were conducted in early 2021. This study aimed to assess the awareness and knowledge of this method after these campaigns. METHODS: We conducted a national cross-sectional online survey about PrEP knowledge and attitudes from March to May 2021. Participants were asked if they had heard of ED-PrEP. Among aware participants, questions about the '2-1-1' method were asked to assess knowledge. Bivariate and multivariate logistic regression analyses were conducted to assess the characteristics of those who were aware of ED-PrEP, and those who had correct knowledge of ED-PrEP. Analysis was restricted to non-HIV-positive cis-GBM who were aware of PrEP. RESULTS: Among the 419 participants eligible for this analysis, 286 (68.3%) had heard of ED-PrEP. Awareness was associated with living in a postcode with ≥10% gay men, PrEP experience, and belief ED-PrEP is effective. Of these 286 participants, 125 (43.7%) correctly answered questions about how to take ED-PrEP. Correct knowledge was associated with PrEP experience and belief ED-PrEP is effective. CONCLUSIONS: A growing proportion of GBM are aware of ED-PrEP, but many still do not know how to take it as per clinical guidelines. More work is needed to increase knowledge among GBM to promote effective use of this method.

Background Overseas-born people who are ineligible for government-subsidised health care experience barriers to accessing HIV pre-exposure prophylaxis (PrEP) in Australia. This study aimed to assess a program providing free PrEP to overseas-born adults at risk of acquiring HIV. Methods Medicare-Ineligible Expanded Implementation in Communities (MI-EPIC) was a single-arm, open-label trial of daily tenofovir disoproxil fumarate/emtricitabine as PrEP. Six clinics recruited Medicare-ineligible adults who met HIV risk criteria in New South Wales, Australia. We recorded data on HIV and sexually transmitted infection (STI) diagnoses, and PrEP dispensing from July 2019 to June 2020. PrEP adherence as a medication possession ratio (MPR) was calculated as pills dispensed divided by days. We administered an optional survey on behaviours and attitudes to PrEP and sexual health. Results The 221 participants (206 men; 93.2%) had a median age of 29years (IQR 26-34). Participants were mostly born in Asia (53.4%), Latin America or the Caribbean (25.3%), or Europe (10.9%). Adherence was high; 190 participants (86.0%) had an MPR of >60%. Of 121 survey participants, 42 (34.7%) completed the survey in a language other than English. Of participants who had not used PrEP in the 6months before enrolment (n=45, 37.2%), the most common reasons were cost (n=22, 48.9%), and lack of knowledge about accessing PrEP (n=20, 44.4%). Conclusions Medicare-ineligible people at risk of HIV demonstrate high adherence when given access to free PrEP and translated information. Increasing PrEP awareness and reducing barriers to accessing PrEP in this high-risk population should be priorities in HIV prevention.

Data from repeated, national behavioural HIV surveillance was used to identify similarities and differences between young gay and bisexual men (YGBM) aged 16-24 (n = 1608) and older GBM aged 25-49 (n = 6266), in order to quantify risks and identify gaps in HIV prevention. Trend analyses from 2014 to 2018 are also reported. While there were similar rates of condomless anal intercourse with casual partners in both age groups, YGBM had lower rates of HIV testing and PrEP use but also fewer male partners. Our results suggest most YGBM have lower HIV risk than older GBM but a minority merit enhanced testing and prevention efforts.

Increasing HIV testing frequency in gay and bisexual men (GBM) is critical to reducing the time between HIV infection and diagnosis. Using anonymous national behavioural surveillance data (2013-2018) from 43,753 surveys of Australian GBM, we examined HIV testing frequency trends and factors differentiating PrEP-users, non-PrEP-users reporting two or more tests in the previous year, and non-PrEP-users reporting less frequent testing. The proportion tested at least annually increased from 64.4% in 2013 to 70.8% in 2018 (p-trend < 0.001), and from 73.9% to 84.6% among the 51.6% of men classified as higher-risk. Among higher-risk men, having two or more tests in the previous year increased from 48.0% to 69.3% (p-trend < 0.001). Among higher-risk non-PrEP-users, it increased from 47.2% to 54.8% (p-trend < 0.001), however, there was a decrease since 2016 (p-trend < 0.001). Among PrEP-users, it increased from 82.1% in 2013 to 97.3% in 2018 (p-trend < 0.001). Non-PrEP-using higher-risk men having less frequent tests reported lower risk than PrEP-users and non-PrEP-using men reporting two or more tests in the previous year. However, recent risk behaviour was not uncommon: nearly half reported condomless sex; one-fifth reported receptive condomless sex with ejaculation; over half reported group sex; one-quarter used drugs for the purposes of sex; and one-fifth had more than ten sex partners. Efforts are needed to encourage frequent testing and PrEP use among non-PrEP-users who are at higher-risk.

BACKGROUND: North Carolina Nutrition and Physical Activity Self-Assessment for Child Care (NAP SACC) resources improve child body mass index (BMI) when the resources are introduced by nurses to child care providers, and offered with workshops and incentives. In San Francisco, public health and child care agencies partnered to adapt NAP SACC resources into an annual "Healthy Apple" quality improvement program (HAP). METHODS: This cluster randomized controlled trial pilot-tested integration of the HAP with bi-annual public health screenings by nurses. All child care centers that participated in Child Care Health Program (CCHP) screenings in San Francisco in 2011-2012 were offered routine services plus HAP in 2012-2013 (CCHP + HAP, n = 19) or routine services with delayed HAP in 2014-2015 (CCHP + HAP Delayed, n = 24). Intention-to-treat analyses (robust SE or mixed models) used 4 years of screening data from 12 to 17 CCHP + HAP and 17 to 20 CCHP + HAP Delayed centers, regarding 791 to 945 children ages 2 to 5y, annually. Year-specific, child level models tested if children in CCHP + HAP centers had greater relative odds of exposure to 3 index best practices and smaller Autumn-to-Spring changes in BMI percentile and z-score than children in CCHP + HAP Delayed centers, controlling for age, sex, and Autumn status. Multi-year, child care center level models tested if HAP support modified year-to-year changes (2013-2014 and 2014-2015 vs 2011-2012) in child care center annual mean Autumn-to-Spring BMI changes. RESULTS: In 2011-2012, the CCHP + HAP and CCHP + HAP Delayed centers had similar index practices (<15% of children were exposed to a physical activity curriculum, staff joining in active play, and drinking water pitchers) and annual BMI changes. In 2013-2014: 60% of children in CCHP + HAP centers were exposed to the 3 index practices vs 19% in CCHP + HAP Delayed centers; Mean (SE) child BMI percentile (-2.6 (0.9), p = 0.003) and z-score (-0.08 (0.03), p = 0.007) decreased more in CCHP + HAP vs CCHP + HAP Delayed centers. In 2014-2015, after all centers were offered HAP, the index practices and BMI changes were improved for all centers vs 2011-2012. CONCLUSIONS: Integration of the HAP with existing public health nursing services was associated with significantly more children exposed to best practices and improvement in child BMI change. The results warrant continued integration of HAP into local public health infrastructure. TRIAL REGISTRATION: ISRCTN18857356 (24/04/2015) Retrospectively registered.

INTRODUCTION: Asthma is a common health condition for children in childcare. National recommendations for asthma in childcare exist. However, no studies have investigated the extent to which childcare centers adhere to these recommendations. We aimed to assess childcare center adherence to National Asthma Education and Prevention Program (NAEPP) recommendations for asthma care and preparedness and to identify characteristics associated with increased adherence to national asthma recommendations. METHODS: We developed a standardized instrument. Each childcare center received a score of 0 through 7 based on number of recommendations met. We conducted t-tests, chi square tests and linear regression to identify childcare center factors associated with increased asthma preparedness. RESULTS: 36 out of 40 eligible childcare centers (90%) participated. These sites served 1570 children primarily between the ages of 2 to 5 years. On average, centers met 3.8 out of 7 (SD = 1.3) recommendations. Staff familiarity caring for children with asthma (p < 0.001) and the center's asthma prevalence (p = 0.01) was positively associated with the center's asthma preparedness. The 3 areas most in need of improvement related to asthma medications, asthma action plans and asthma policies. None of the managers reported being familiar with the NAEPP recommendations. DISCUSSION: There is room for improvement in the asthma care and preparedness of childcare centers. The 3 areas in which centers performed poorly (appropriate asthma medication management, use of asthma action plans, and presence of appropriate asthma policies) suggest that closer collaboration between clinicians and childcare centers may be a key to improving asthma management for young children.

Cancer develops from abnormal cell growth in the body, causing significant mortalities every year. To date, potent therapeutic approaches have been developed to eradicate tumor cells, but intolerable toxicity and drug resistance can occur in treated patients, limiting the efficiency of existing treatment strategies. Therefore, searching for novel genes critical for cancer progression and therapeutic response is urgently needed for successful cancer therapy. Recent advances in bioinformatics and proteomic techniques have allowed the identification of a novel category of peptides encoded by non-canonical open reading frames (ncORFs) from historically non-coding genomic regions. Surprisingly, many ncORFs express functional microproteins that play a vital role in human cancers. In this review, we provide a comprehensive description of different ncORF types with coding capacity and technological methods in discovering ncORFs among human genomes. We also summarize the carcinogenic role of ncORFs such as pTINCR and HOXB-AS3 in regulating hallmarks of cancer, as well as the roles of ncORFs such as HOXB-AS3 and CIP2A-BP in cancer diagnosis and prognosis. We also discuss how ncORFs such as AKT-174aa and DDUP are involved in anti-cancer drug response and the underestimated potential of ncORFs as therapeutic targets.
RESUMO
Evaluating HIV preexposure prophylaxis (PrEP) use and HIV risk events concurrently remains challenging. We developed a single question method for measuring prevention-effective adherence with PrEP in self-report questionnaires. In a questionnaire completed by 409 gay and bisexual men, 46% reported condomless anal sex that was not covered by their own PrEP use, and this was more common among younger, lower-income participants. Refining this questionnaire item could improve measurement of prevention-effective adherence.
