Abstract
Although suicide rates are stable or decreasing among White communities, rates are increasing among Black communities, a trend that appears to be disproportionately affecting Black lesbian, gay, bisexual, and queer (LGBQ) people. To understand the structural drivers and mechanisms of these trends, we examined associations between U.S. state-level racist and heterosexist criminal legal policies and policing, discrimination, and suicidality among White and Black, heterosexual and LGBQ, communities. We recruited 5,064 participants in 2021 using online census-driven quota sampling. Structural equation modeling estimated associations from objective indicators of racist and heterosexist criminal legal policies to self-reported police stops, discrimination, and suicidal ideation and behavior. For White heterosexual participants, racist (β = -.22, SE = 0.03, p < .001) and heterosexist (β = -.26, SE = 0.03, p < .001) policies were negatively associated with police stops. For White LGBQ participants, racist and heterosexist policies were not significantly associated with police stops. For Black heterosexual participants, racist (β = .30, SE = 0.11, p = .005), but not heterosexist, policies were positively associated with police stops. For Black LGBQ participants, racist (β = .57, SE = 0.08, p < .001) and heterosexist (β = .65, SE = 0.09, p < .001) policies were positively associated with police stops which, in turn, were positively associated with discrimination and suicidal ideation and behavior. Results provide evidence that racist and heterosexist state policies are linked to policing and interpersonal drivers of suicide inequities and suggest that repealing/preventing oppressive policies should be a suicide prevention imperative.

Abstract
CD4 T follicular helper cells (Tfh) are essential for establishing serological memory and have distinct helper attributes that impact both the quantity and quality of the antibody response. Insights into Tfh subsets that promote antibody persistence and functional capacity can critically inform vaccine design. Based on the Tfh profiles evoked by the live attenuated measles virus vaccine, renowned for its ability to establish durable humoral immunity, we investigated the potential of a Tfh1/17 recall response during the boost phase to enhance persistence of HIV-1 Envelope (Env) antibodies in rhesus macaques. Using a DNA-prime encoding gp160 antigen and Tfh polarizing cytokines (interferon protein-10 (IP-10) and interleukin-6 (IL-6)), followed by a gp140 protein boost formulated in a cationic liposome-based adjuvant (CAF01), we successfully generated germinal center (GC) Tfh1/17 cells. In contrast, a similar DNA-prime (including IP-10) followed by gp140 formulated with monophosphoryl lipid A (MPLA) +QS-21 adjuvant predominantly induced GC Tfh1 cells. While the generation of GC Tfh1/17 cells with CAF01 and GC Tfh1 cells with MPLA +QS-21 induced comparable peak Env antibodies, the latter group demonstrated significantly greater antibody concentrations at week 8 after final immunization which persisted up to 30 weeks (gp140 IgG ng/ml- MPLA; 5500; CAF01, 2155; p<0.05). Notably, interferon γ+Env-specific Tfh responses were consistently higher with gp140 in MPLA +QS-21 and positively correlated with Env antibody persistence. These findings suggest that vaccine platforms maximizing GC Tfh1 induction promote persistent Env antibodies, important for protective immunity against HIV.

Abstract
Route of immunization can markedly influence the quality of immune response. Here, we show that intradermal (ID) but not intramuscular (IM) modified vaccinia Ankara (MVA) vaccinations provide protection from acquisition of intravaginal tier2 simian-human immunodeficiency virus (SHIV) challenges in female macaques. Both routes of vaccination induce comparable levels of serum IgG with neutralizing and non-neutralizing activities. The protection in MVA-ID group correlates positively with serum neutralizing and antibody-dependent phagocytic activities, and envelope-specific vaginal IgA; while the limited protection in MVA-IM group correlates only with serum neutralizing activity. MVA-ID immunizations induce greater germinal center Tfh and B cell responses, reduced the ratio of Th1 to Tfh cells in blood and showed lower activation of intermediate monocytes and inflammasome compared to MVA-IM immunizations. This lower innate activation correlates negatively with induction of Tfh responses. These data demonstrate that the MVA-ID vaccinations protect against intravaginal SHIV challenges by modulating the innate and T helper responses.

Abstract
OBJECTIVES This uncontrolled pilot study examined the feasibility, acceptability, and preliminary HIV and psychological health effects of iTHRIVE 365, a multicomponent intervention designed by and for Black same gender loving men (SGLM) to promote: health knowledge and motivation, Black SGLM social support, affirming health care, and housing and other economic resources. DESIGN METHODS We conducted a 14-day daily diary study with 32 Black SGLM living with HIV connected to THRIVE SS in Atlanta, GA. Daily surveys assessed intervention engagement, antiretroviral medication (ART) use, depressive symptoms, anxiety symptoms, and emotion regulation difficulties. App paradata (ie, process data detailing app usage) assessed amount of intervention engagement via page access. Participants began receiving access to the intervention on day 7. After the 14-day daily diary period, participants responded to follow-up items on the user-friendliness, usefulness, helpfulness, and whether they would recommend iTHRIVE 365 to others. Chi-square analyses examined associations between intervention engagement and ART use, and dynamic structural equation modelling assessed longitudinal associations from intervention engagement to next-day psychological health. This intervention trial is registered on ClinicalTrials.gov (NCT05376397). RESULTS On average, participants engaged with iTHRIVE 365 over once every other day and accessed intervention pages 4.65 times per day. Among participants who engaged with the intervention, 78% reported it was helpful to extremely helpful, 83% reported it was moderately to extremely useful, and 88% reported it was user-friendly and they would recommend it to others. On intervention engagement days, participants had higher odds of ART use, χ 2 (1) = 4.09, P = 0.04, than intervention nonengagement days. On days after intervention engagement, participants showed non-null decreases in depressive symptoms (τ = -0.14; 95% CI : = [-0.23, -0.05]) and emotion regulation difficulties (τ = -0.16; 95% CI : = [-0.24, -0.02]). CONCLUSIONS Findings suggest iTHRIVE 365 is feasible, acceptable, and positively affects daily ART use, depressive symptoms, and emotion regulation difficulties.

Abstract
Researchers are increasingly recognizing the importance of studying and addressing intersectional stigma within the field of HIV. Yet, researchers have, arguably, struggled to operationalize intersectional stigma. To ensure that future research and methodological innovation is guided by frameworks from which this area of inquiry has arisen, we propose a series of core elements for future HIV-related intersectional stigma research. These core elements include multidimensional, multilevel, multidirectional, and action-oriented methods that sharpen focus on, and aim to transform, interlocking and reinforcing systems of oppression. We further identify opportunities for advancing HIV-related intersectional stigma research, including reducing barriers to and strengthening investments in resources, building capacity to engage in research and implementation of interventions, and creating meaningful pathways for HIV-related intersectional stigma research to produce structural change. Ultimately, the expected payoff for incorporating these core elements is a body of HIV-related intersectional stigma research that is both better aligned with the transformative potential of intersectionality and better positioned to achieve the goals of Ending the HIV Epidemic in the United States and globally.

Abstract
AbstractPurpose: We extended the focus on body image research beyond cisgender, White sexual minority men (SMM) by describing body image concerns among Black and Latinx SMM and transgender/gender nonconforming (TGNC) adults and by examining protective effects of community connection. Methods: From 2016 to 2020, 447 Black and Latinx SMM (94%) and TGNC (6%) individuals in Los Angeles provided data semiannually. Participant endorsement of any body image concerns was determined by five body image codes (weight, fitness, appearance, body area dissatisfaction, and general body image) applied to participants' open-ended lists of health and body concerns. Fixed effects multivariable logistic regression was performed to examine the association between gay and racial/ethnic community connection and odds of any body image concerns, accounting for multiple records per person. An interaction term between gay and racial/ethnic community connection approximated the protective effect of connection to multiple, intersecting communities. Results: The majority of participants (51%) reported a body image concern, most commonly weight concerns, at least once across three years. Body image concerns were more common among Latinx participants (χ2 = 17.79, p < 0.001) and participants experiencing food insecurity (χ2 = 4.11, p = 0.04) and unmet basic financial needs (χ2 = 10.56, p = 0.001). Gay community connection was protective against body image concerns, but only for participants who had high racial/ethnic community connection (adjusted odds ratio = 0.87, p = 0.05). Conclusion: Body image concerns were notable, especially among those with low community connection and higher socioeconomic burden. These findings suggest that building connections within SMM/TGNC and racial/ethnic communities may aid in building a support network that buffers against body image concerns.

Abstract
BACKGROUND People who inject drugs (PWID) lag behind other key populations in HIV care continuum outcomes. The impacts of criminal justice reform and increasing drug treatment access on HIV have been underexplored. METHODS We developed agent-based models (ABM) of sexual partnerships among PWID and non-PWID, and injection equipment-sharing partnerships among PWID in five US cities (Baltimore, Boston, Miami, New York City, San Francisco) over 3 years. The first set of ABM projected changes in partnership discordance among PWID as a function of decreasing ZIP code-level incarceration rates. The second set projected discordance as a function of increasing ZIP code-level drug treatment access. ABM were parameterized and validated overall, and by city and PWID race/ethnicity (Black, Latino, White) using National HIV Behavioral Surveillance data, administrative ZIP code-level data, surveillance reports and prior literature. Informed by research on prisoner release and community-level HIV prevalence, reductions in incarceration rates were fixed at 5% and 30% and respectively projected to increase ZIP code-level HIV prevalence by 2% and 12%. Increases in drug treatment access were fixed at 30% and 58%. RESULTS In each city, a 30% reduction in ZIP code-level incarceration rates and 12% increase in ZIP code-level HIV prevalence significantly increased sero-discordance among at least one racial/ethnic group of PWID by 1-3 percentage points. A 5% reduction in incarceration rates, and 30% and 58% increases in drug treatment access, led to isolated significant changes in sero-discordance among Black and White PWID that were less than 1 percentage point. CONCLUSION Reductions in incarceration rates may lead to short-term increases in sero-discordant partnerships among some PWID by increasing community-level HIV prevalence. Efforts to increase HIV testing, engagement in care and community reintegration post release, should be strengthened in the wake of incarceration reform. Additional research should confirm these findings and explore the lack of widespread impacts of drug treatment in this study.

Abstract
Ongoing severe acute respiratory syndrome coronavirus–2 (SARS-CoV-2) vaccine development is focused on identifying stable, cost-effective, and accessible candidates for global use, specifically in low- and middle-income countries. Here, we report the efficacy of a rapidly scalable, novel yeast-expressed SARS-CoV-2–specific receptor binding domain (RBD)–based vaccine in rhesus macaques. We formulated the RBD immunogen in alum, a licensed and an emerging alum-adsorbed TLR-7/8-targeted, 3M-052-alum adjuvant. The RBD + 3M-052-alum-adjuvanted vaccine promoted better RBD binding and effector antibodies, higher CoV-2 neutralizing antibodies, improved TH1-biased CD4+ T cell reactions, and increased CD8+ T cell responses when compared with the alum-alone adjuvanted vaccine. RBD + 3M-052-alum induced a significant reduction of SARS-CoV-2 virus in the respiratory tract upon challenge, accompanied by reduced lung inflammation when compared with unvaccinated controls. Anti-RBD antibody responses in vaccinated animals inversely correlated with viral load in nasal secretions and bronchoalveolar lavage (BAL). RBD + 3M-052-alum blocked a post-SARS-CoV-2 challenge increase in CD14+CD16++ intermediate blood monocytes, and fractalkine, MCP-1 (monocyte chemotactic protein–1), and TRAIL (tumor necrosis factor–related apoptosis-inducing ligand) in the plasma. Decreased plasma analytes and intermediate monocyte frequencies correlated with reduced nasal and BAL viral loads. Last, RBD-specific plasma cells accumulated in the draining lymph nodes and not in the bone marrow, contrary to previous findings. Together, these data show that a yeast-expressed, RBD-based vaccine + 3M-052-alum provides robust immune responses and protection against SARS-CoV-2, making it a strong and scalable vaccine candidate.

Abstract
The present study investigates the bioaccumulation of the insensitive munition compounds 2,4-dinitroanisole (DNAN) and 3-nitro-1,2,4-triazol-5-one (NTO), developed for future weapons systems to replace current munitions containing sensitive explosives. The earthworm Eisenia andrei was exposed to sublethal concentrations of DNAN or NTO amended in Sassafras sandy loam. Chemical analysis indicated that 2- and 4-amino-nitroanisole (2-ANAN and 4-ANAN, respectively) were formed in DNAN-amended soils. The SumDNAN (sum of DNAN, 2-ANAN, and 4-ANAN concentrations) in soil decreased by 40% during the 14-d exposure period. The SumDNAN in the earthworm body residue increased until day 3 and decreased thereafter. Between days 3 and 14, there was a 73% decrease in tissue uptake that was greater than the 23% decrease in the soil concentration, suggesting that the bioavailable fraction may have decreased over time. By day 14, the DNAN concentration accounted for only 45% of the SumDNAN soil concentration, indicating substantial DNAN transformation in the presence of earthworms. The highest bioaccumulation factor (BAF; the tissue-to-soil concentration ratio) was 6.2 ± 1.0 kg/kg (dry wt) on day 3 and decreased to 3.8 ± 0.8 kg/kg by day 14. Kinetic studies indicated a BAF of 2.3 kg/kg, based on the earthworm DNAN uptake rate of 2.0 ± 0.24 kg/kg/d, compared with the SumDNAN elimination rate of 0.87 d-1 (half-life = 0.79 d). The compound DNAN has a similar potential to bioaccumulate from soil compared with trinitrotoluene. The NTO concentration in amended soil decreased by 57% from the initial concentration (837 mg NTO/kg dry soil) during 14 d, likely due to the formation of unknown transformation products. The bioaccumulation of NTO was negligible (BAF ≤ 0.018 kg/kg dry wt). Environ Toxicol Chem 2021;40:1713-1725. © 2021 SETAC.

Abstract
New modalities of Pre-exposure Prophylaxis (PrEP) such as long-acting injectable PrEP (LAI-PrEP) promise increased prevention of HIV transmission; however, similar biomedical interventions have not been met with universal adoption by healthcare providers or populations most affected by HIV. This qualitative study explores healthcare provider considerations for the rollout of LAI-PrEP. Eleven key-informant in-depth interviews were conducted with clinicians who prescribe daily oral PrEP. Participants reviewed a currently proposed LAI regimen and were asked to reflect on its implications for their clinical practice. Interviews were transcribed verbatim and thematically coded, with results organized using the Consolidated Framework for Implementation Research (CFIR). All participants expressed interest in prescribing LAI-PrEP and anticipated that at least some patients would be interested. Participants identified characteristics of the intervention, inner intervention setting, and outer intervention setting that will be influential in bringing LAI-PrEP to scale. Clinicians in the South have unique insights into the challenges of and opportunities for successful rollout of future PrEP regimens. Bringing these insights into a CFIR framework highlights the nuances surrounding LAI-PrEP, including structural concerns such as cost barriers and access to in-person healthcare services. It is critical to address these challenges to ensure successful implementation of new PrEP formulations.

Abstract
Background Vasculogenesis in amniotes is often viewed as two spatially and temporally distinct processes, occurring in the yolk sac and in the embryo. However, the spatial origins of the cells that form the primary intra-embryonic vasculature remain uncertain. In particular, do they obtain their haemato-endothelial cell fate in situ, or do they migrate from elsewhere? Recently developed imaging techniques, together with new Tal1 and existing Flk1 reporter mouse lines, have allowed us to investigate this question directly, by visualising cell trajectories live and in three dimensions. Results We describe the pathways that cells follow to form the primary embryonic circulatory system in the mouse embryo. In particular, we show that Tal1-positive cells migrate from within the yolk sac, at its distal border, to contribute to the endocardium, dorsal aortae and head vasculature. Other Tal1 positive cells, similarly activated within the yolk sac, contribute to the yolk sac vasculature. Using single-cell transcriptomics and our imaging, we identify VEGF and Apela as potential chemo-attractants that may regulate the migration into the embryo. The dorsal aortae and head vasculature are known sites of secondary haematopoiesis; given the common origins that we observe, we investigate whether this is also the case for the endocardium. We discover cells budding from the wall of the endocardium with high Tal1 expression and diminished Flk1 expression, indicative of an endothelial to haematopoietic transition. Conclusions In contrast to the view that the yolk sac and embryonic circulatory systems form by two separate processes, our results indicate that Tal1-positive cells from the yolk sac contribute to both vascular systems. It may be that initial Tal1 activation in these cells is through a common mechanism.

Abstract
CD4 T follicular helper (Tfh) cells are important for the generation of durable and specific humoral protection against viral infections. The degree to which SARS-CoV-2 infection generates Tfh cells and stimulates the germinal center (GC) response is an important question as we investigate vaccine induced immunity against COVID-19. Here, we report that SARS-CoV-2 infection in rhesus macaques, either infused with convalescent plasma, normal plasma, or receiving no infusion, resulted in transient accumulation of pro-inflammatory monocytes and proliferating Tfh cells with a Th1 profile in peripheral blood. CD4 helper cell responses skewed predominantly toward a Th1 response in blood, lung, and lymph nodes. SARS-CoV-2 Infection induced GC Tfh cells specific for the SARS-CoV-2 spike and nucleocapsid proteins, and a corresponding early appearance of antiviral serum IgG antibodies. Collectively, the data show induction of GC responses in a rhesus model of mild COVID-19.

Abstract
BACKGROUND To examine trends in state-level policy support for sexual minorities and HIV outcomes among men who have sex with men (MSM). METHODS This longitudinal analysis linked state-level policy support for sexual minorities [N = 94 metropolitan statistical areas (MSAs) in 38 states] to 7 years of data (2008-2014) from the Centers for Disease Control and Prevention on HIV outcomes among MSM. Using latent growth mixture modeling, we combined 11 state-level policies (eg, nondiscrimination laws including sexual orientation as a protected class) from 1999 to 2014, deriving the following 3 latent groups: consistently low policy support, consistently high policy support, and increasing trajectory of policy support. Outcomes were HIV diagnoses per 10,000 MSM, late diagnoses (number of deaths within 12 months of HIV diagnosis and AIDS diagnoses within 3 months of HIV diagnosis) per 10,000 MSM, AIDS diagnoses per 10,000 MSM with HIV, and AIDS-related mortality per 10,000 MSM with AIDS. RESULTS Compared with MSAs in states with low policy support and increasing policy support for sexual minorities, MSAs in states with the highest level of policy support had lower risks of HIV diagnoses [risk difference (RD) = -37.9, 95% confidence interval (CI): -54.7 to -21.0], late diagnoses (RD = -12.5, 95% CI: -20.4 to -4.7), and AIDS-related mortality (RD = -33.7, 95% CI: -61.2 to -6.2), controlling for time and 7 MSA-level covariates. In low policy support states, 27% of HIV diagnoses, 21% of late diagnoses, and 10% of AIDS deaths among MSM were attributable to the policy climate. CONCLUSION The state-level policy climate related to sexual minorities was associated with HIV health outcomes among MSM and could be a potential public health tool for HIV prevention and care.

Abstract
We present a supercomputer-driven pipeline for in-silico drug discovery using enhanced sampling molecular dynamics (MD) and ensemble docking. We also describe preliminary results obtained for 23 systems involving eight protein targets of the proteome of SARS CoV-2. THe MD performed is temperature replica-exchange enhanced sampling, making use of the massively parallel supercomputing on the SUMMIT supercomputer at Oak Ridge National Laboratory, with which more than 1ms of enhanced sampling MD can be generated per day. We have ensemble docked repurposing databases to ten configurations of each of the 23 SARS CoV-2 systems using AutoDock Vina. We also demonstrate that using Autodock-GPU on SUMMIT, it is possible to perform exhaustive docking of one billion compounds in under 24 hours. Finally, we discuss preliminary results and planned improvements to the pipeline, including the use of quantum mechanical (QM), machine learning, and AI methods to cluster MD trajectories and rescore docking poses.

Abstract
CD4 T follicular helper (T fh ) cells are important for the generation of long-lasting and specific humoral protection against viral infections. The degree to which SARS-CoV-2 infection generates T fh cells and stimulates the germinal center response is an important question as we investigate vaccine options for the current pandemic. Here we report that, following infection with SARS-CoV-2, adult rhesus macaques exhibited transient accumulation of activated, proliferating T fh cells in their peripheral blood on a transitory basis. The CD4 helper cell responses were skewed predominantly toward a T h 1 response in blood, lung, and lymph nodes, reflective of the interferon-rich cytokine environment following infection. We also observed the generation of germinal center T fh cells specific for the SARS-CoV-2 spike (S) and nucleocapsid (N) proteins, and a corresponding early appearance of antiviral serum IgG antibodies but delayed or absent IgA antibodies. Our data suggest that a vaccine promoting Th1-type Tfh responses that target the S protein may lead to protective immunity.

Abstract
Background Much has been written about the impact of human immunodeficiency virus (HIV) among young (13-24) sexual minority men (SMM). Evidence for concern is substantial for emerging adult (18-24 years) SMM. Data documenting the burden and associated risk factors of HIV among adolescent SMM (<18 years) remain limited. Methods Adolescent SMM aged 13-18 years were recruited in 3 cities (Chicago, New York City, and Philadelphia) for interview and HIV testing. We used χ2 tests for percentages of binary variables and 1-way analysis of variance for means of continuous variables to assess differences by race/ethnicity in behaviors. We calculated estimated annual HIV incidence density (number of HIV infections per 100 person-years [PY] at risk). We computed Fisher's exact tests to determine differences in HIV prevalence by selected characteristics. Results Of 415 sexually active adolescent SMM with a valid HIV test result, 25 (6%) had a positive test. Estimated annual HIV incidence density was 3.4/100 PY; incidence density was highest for blacks, followed by Hispanics, then whites (4.1, 3.2, and 1.1/100 PY, respectively). Factors associated with higher HIV prevalence included black race; ≥4 male partners, condomless anal sex, and exchange sex in the past 12 months; and a recent partner who was older, black, HIV-infected, or had ever been in jail or prison (P < .05). Conclusions HIV-related risk behaviors, prevalence, and estimated incidence density for adolescent SMM were high, especially for minority SMM. Our findings suggest that initiating intervention efforts early may be helpful in combating these trends.

Abstract
Minority stress theory posits that homonegativity-whether experienced, anticipated, or internalized-adversely impacts health. We conducted qualitative interviews with 28 YB-GBMSM living with HIV to explore manifestations of homonegativity over the life course. Thematic analysis identified patterns in the ways that homonegativity was discussed at different points in participants' lives. Stifling, and sometimes traumatic, familial and religious environments led to experienced homonegativity early in life. These experiences led to anticipated and internalized homonegativity, which in turn shaped sexual identity formation processes in adolescence and into young adulthood. Ultimately, many participants distanced themselves from home environments, seeking and often finding extrafamilial support. Most participants eventually reached self-acceptance of both their sexuality and HIV status. In conclusion, experienced, anticipated and internalized homonegativity were pervasive as YB-GBMSM navigated family and religious environments over the life course. Future interventions should work with youth, families, and churches to prevent these harmful experiences.

Abstract
OBJECTIVES Emerging literature shows that racialised police brutality, a form of structural racism, significantly affects health and well-being of racial/ethnic minorities in the USA. While public health research suggests that structural racism is a distal determinant of sexually transmitted infections (STIs) among Black people, no studies have empirically linked police violence to STIs. To address this gap, our study measures associations between police killings and rates of STIs among Black residents of US metropolitan statistical areas (MSAs). METHODS This cross-sectional ecological analysis assessed associations between the number of Black people killed by police in 2015 and rates of primary and secondary syphilis, gonorrhoea and chlamydia per 100 000 Black residents of all ages in 2016 in 75 large MSAs. Multivariable models controlled for MSA-level demographic and socioeconomic characteristics, police expenditures, violent crime, arrest and incarceration rates, insurance rates and healthcare funding. RESULTS In 2015, the median number of Black people killed by police per MSA was 1.0. In multivariable models, police killings were positively and significantly associated with syphilis and gonorrhoea rates among Black residents. Each additional police killing in 2015 was associated with syphilis rates that were 7.5% higher and gonorrhoea rates that were 4.0% higher in 2016. CONCLUSIONS Police killings of Black people may increase MSA-level risk of STI infections among Black residents. If future longitudinal analyses support these findings, efforts to reduce STIs among Black people should include reducing police brutality and addressing mechanisms linking this violence to STIs.

Abstract
INTRODUCTION Youth under the age of 25 are at high risk for HIV infection. While pre-exposure prophylaxis (PrEP) has the potential to curb new infections within this population, it is unclear how country-specific laws and policies that govern youth access to sexual and reproductive health (SRH) services impact access to PrEP. The purpose of this review was to analyse laws and policies concerning PrEP implementation and SRH services available to youth in countries with a high HIV incidence. To the best of our knowledge this is the first systematic assessment of country-level policies that impact the availability of PrEP to adolescent populations. METHODS We conducted a review of national policies published on or before 12 June 2018 that could impact adolescents' access to PrEP, SRH services and ability to consent to medical intervention. Countries were included if: (1) there was a high incidence of HIV; (2) they had active PrEP trials or PrEP was available for distribution; (3) information regarding PrEP guidelines were publicly available. We also included a selected number of countries with lower adolescent HIV incidence. Internet and legal database searches were used to identify policies relevant to adolescent PrEP (e.g. age of consent to HIV testing). RESULTS AND DISCUSSION Fifteen countries were selected for inclusion in this review. Countries varied considerably in their respective laws and policies governing adolescents' access to PrEP, HIV testing and SRH services. Six countries had specific polices around the provision of PrEP to youth under the age of 18. Five countries required people to be 18 years or older to access HIV testing, and six countries had specific laws addressing adolescent consent for- and access to- contraceptives. CONCLUSIONS Adolescents' access to PrEP without parental consent remains limited or uncertain in many countries where this biomedical intervention is needed. Observational and qualitative studies are needed to determine if and how adolescent consent laws are followed in relation to adolescent PrEP provisions. Intensified efforts to amend laws that limit adolescent access to PrEP and restrict the establishment of national guidelines supporting adolescent PrEP are also needed to address the epidemic in this group.

Abstract
Young Black gay/bisexual and other men who have sex with men (YB-GBMSM) are disproportionately impacted by HIV/AIDS. Novel intervention strategies are needed to optimize engagement in HIV care for this population. We sought to develop a group-level intervention to enhance resilience by augmenting social capital (defined as the sum of resources in an individual's social network) among YB-GBMSM living with HIV, with the ultimate goal of improving engagement in HIV care. Our multiphase, community-based participatory research (CBPR) intervention development process included: (1) Development and maintenance of a youth advisory board (YAB) comprised of YB-GBMSM living with HIV; (2) Qualitative in-depth interviews with YB-GBMSM living with HIV; (3) Qualitative in-depth interviews with care and service providers at clinics and community-based organizations; and (4) Collaborative development of intervention modules and activities with our YAB, informed by social capital theory and our formative research results. The result of this process is Brothers Building Brothers By Breaking Barriers, a two-day, 10-module group-level intervention. The intervention does not focus exclusively on HIV, but rather takes a holistic approach to supporting youth and enhancing resilience. Intervention modules aim to develop resilience at the individual level (exploration of black gay identity, development of critical self-reflection and coping skills), social network level (exploring strategies for navigating family and intimate relationships) and community level (developing strategies for navigating clinical spaces and plans for community participation). Most intervention activities are interactive, in order to facilitate new social network connections - and accompanying social capital - within intervention groups. In summary, our intensive CBPR approach resulted in a novel, culturally-specific intervention designed to enhance HIV care engagement by augmenting resilience and social capital among YB-GBMSM living with HIV.

Abstract
Social capital, the sum of an individual's resource-containing social network connections, has been proposed as a facilitator of successful HIV care engagement. We explored relationships between social capital, psychological covariates (depression, stigma and internalized homonegativity), and viral suppression in a sample of young Black gay, bisexual and other men who have sex with men (YB-GBMSM). We recruited 81 HIV-positive YB-GBMSM 18-24 years of age from a clinic setting. Participants completed a cross-sectional survey, and HIV-1 viral load (VL) measurements were extracted from the medical record. Sixty-five percent (65%) were virally suppressed (HIV-1 VL ≤ 40 copies/ml). Forty-seven percent (47%) had a positive depression screen. Depressive symptoms affected viral suppression differently in YB-GBMSM with lower vs. higher social capital (p = 0.046, test for statistical interaction between depression and social capital). The odds of viral suppression among YB-GBMSM with lower social capital was 93% lower among those with depressive symptoms (OR 0.07, p = 0.002); however, there was no association between depressive symptoms and viral suppression among those with higher social capital. Our results suggest that social capital may buffer the strong negative effects of depressive symptoms on clinical outcomes in YB-GBMSM living with HIV. In addition to treating depression, there is a role for interventions to augment social capital among YB-GBMSM living with HIV as a strategy for enhancing care engagement.

Abstract
Ureteric injury is a recognized complication of hysterectomy and may present with obstruction or fistula. Between 1987 and 1989 in Oxford nine patients with 10 injured ureters underwent attempted retrograde placement of double J stents. Three patients had successful outcomes and one patient with bilateral ureteric obstruction required reimplantation of the right ureter after successful stenting of the left ureter. One patient required removal of a stent due to irritation but her fistula eventually closed. In three patients placement was unsuccessful and in one patient injury to the bladder base prevented the ureteric orifices from being seen and hence stenting was not possible. Thus five of these 10 injured ureters were managed successfully with double J stents. We advocate the initial use of double J stents in gynaecological ureteric injury. This approach is simple and may cure the fistula. If it is unsuccessful, subsequent reimplantation is not hindered.

Abstract
Abstract
Background: Chemotherapy remains the mainstay of therapy for patients with metastatic triple negative breast cancer (TNBC). We hypothesized that the addition of biologic agents targeting key pathways (bevacizumab targeting angiogenesis and erlotinib directed against EGFR) may prolong progression free survival (PFS) and offer a novel treatment strategy free from chemotherapy for patients with metastatic TNBC.
Methods: Patients with TNBC receiving initial therapy for metastatic disease were eligible for this multicenter phase II trial (NCT00733408) conducted at an academic center and affiliated, community practice sites. Induction therapy included nab-paclitaxel 100 mg/m2 IV Qweek (wk) and Bevacizumab 10 mg/kg IV Q2wks x 24 weeks. Patients free of progression at 24 wks began maintenance therapy with bevacizumab 10 mg/kg IV Q2wks and erlotinib 150 mg po daily until progression with radiographic assessment every 8 wks. Primary objective was PFS with secondary objectives of response rate, overall survival (OS) and safety. All eligible patients were included in the analysis of PFS and OS. Response was evaluated among patients with measurable disease by RECIST 1.1 with central review. Patients with inadequate disease assessments were coded as non-responders. Kaplan-Meier method was used to estimate PFS and OS with patients censored at date of last tumor assessment (PFS) or date of last follow up (OS).
Results: From April 2009 – December 2015, 58 patients (median age 54, range 33-83) were enrolled; 56 (97%) had measurable disease, and all had metastatic TNBC by local assessment. 33 (57%) patients completed induction; 22 (38%) came off study during induction; 3 (5%) continue on maintenance therapy. 4 patients discontinued therapy prior to first assessment. As of June 8, 2016, 53 patients (91%) have progressed. Median follow up for surviving patients is 14.5 months (range 4.1-65.4). Median PFS is 7.7 months (95% CI 5.7, 9.5). Of 56 patients with measurable disease, 38 (66%) had partial response (PR); 10 (17%) with stable disease for clinical benefit rate (CBR) of 86%. Median OS is 18.2 months (95% CI 16.3, 24.5). Most common grade 3-4 toxicities during induction were neutropenia [17 (29%), 1 grade 4], fatigue [13 (22%), all grade 3], leukopenia [7 (12%), all grade 3], and neuropathy [7 (12%), all grade 3]. Rash was most common ≥ grade 3 toxicity during maintenance [4 (7%), grade 3]. One patient experienced clinical CHF during maintenance month 16 requiring bevacizumab discontinuation. Conclusions: Nab-paclitaxel and bevacizumab followed by maintenance targeted therapy with bevacizumab and erlotinib was well tolerated. While the observed PFS did not meet pre-specified criteria of interest, the majority of patients experienced clinical benefit (86%) with 30 (57%) receiving maintenance targeted therapy. Correlative studies are ongoing. Supported by Genentech (OSI4266s), Celegene (AX-CL-BRST-PI-003828) and Janssen.

Abstract
MSM bear a disproportionate burden of the HIV epidemic. Enacted stigma (overt negative actions) against sexual minorities may play an important role in increasing HIV risk among this population. Using data from the 2011 National HIV Behavioral Surveillance system, MSM cycle, we examined the independent associations between three measures of enacted stigma (verbal harassment, discrimination, physical assault) and engagement in each of four HIV-related risk behaviors as outcomes: condomless anal intercourse (CAI) at last sex with a male partner of HIV discordant or unknown status and, in the past 12 months, CAI with a male partner, ≥4 male sex partners, and exchange sex. Of 9819 MSM, 32% experienced verbal harassment in the past 12 months, 23% experienced discrimination, and 8% experienced physical assault. Discordant CAI at last sex with a male partner was associated with previous discrimination and physical assault. Past 12 month CAI with a male partner, ≥4 male sex partners, and exchange sex were each associated with verbal harassment, discrimination, and physical assault. These findings indicate that a sizable proportion of MSM report occurrences of past 12 month enacted stigma and suggest that these experiences may be associated with HIV-related risk behavior. Addressing stigma towards sexual minorities must involve an integrated, multi-faceted approach, including interventions at the individual, community, and societal level.

Abstract
Social order, to remain stable, needs the voluntary compliance of the majority of the population. Such consent requires normative justification. The rational foundation of the rule of law and the democratic state rests on the presumption of the equality of every citizen. Male domination of females nevertheless remains universal even in the most advanced democratic nation states because it is legitimized by the shared assumption that patriarchy reflects the will of God or is dictated by nature. Freud's diagnosis of patriarchy as a collective neurosis of the group mind negates every possible normative justification that can be made for gender hierarchy. Freud made extensive references to myth in developing his analysis of the neurotic foundations of social order. An analysis of the structure of myth suggests that ideological seduction rather than God, nature or biology determines male dominance.

Abstract
This study investigated whether stress symptoms related to attention deficit previously found for a sample ( n = 149) of Chicago-area college students 1 to 5 weeks after the September 11th attacks were present in a comparable sample ( n = 129) 12 to 14 months later. As hypothesized, the later participants had a significantly lower mean score on the scale, Attention Deficit of the Smith Stress Symptoms Inventory, than a different group of participants tested immediately after the attacks. Mean Attention Deficit scores for groups after one year and immediately before September 11th ( n = 320) did not differ statistically. Findings are consistent with the interpretation that elevations in scores on Attention Deficit immediately after September 11th were indeed associated with the catastrophic attacks and not artifacts of time of examination. Consistent with previous research with this inventory, disaster-related traumatic stress scores are lower over time, although here no control group was included.

Abstract
Several studies have implicated the sexual networks of Black men who have sex with men (MSM) as facilitating disproportionally high rates of new HIV infections within this community. Although structural disparities place these networks at heightened risk for infection, HIV prevention science continues to describe networks as the cause for HIV disparities, rather than an effect of structures that pattern infection. We explore the historical relationship between public health and Black MSM, arguing that the current articulation of Black MSM networks is too often incomplete and counterproductive. Public health can offer a counternarrative that reconciles epidemiology with the social justice that informs our discipline, and that is required for an effective response to the epidemic among Black MSM.

Abstract
BACKGROUND Over half of human immunodeficiency virus (HIV) infections in the United States occur among men who have sex with men (MSM). Among MSM, 16% of estimated new infections in 2010 occurred among black MSM <25 years old. METHODOLOGY We analyzed National HIV Behavioral Surveillance data on MSM from 20 cities. Poisson models were used to test racial disparities, by age, in HIV prevalence, HIV awareness, and sex behaviors among MSM in 2014. Data from 2008, 2011, and 2014 were used to examine how racial/ethnic disparities changed across time. RESULTS While black MSM did not report greater sexual risk than other MSM, they were most likely to be infected with HIV and least likely to know it. Among black MSM aged 18-24 years tested in 2014, 26% were HIV positive. Among white MSM aged 18-24 years tested in 2014, 3% were HIV positive. The disparity in HIV prevalence between black and white MSM increased from 2008 to 2014, especially among young MSM. CONCLUSIONS Disparities in HIV prevalence between black and white MSM continue to increase. Black MSM may be infected with HIV at younger ages than other MSM and may benefit from prevention efforts that address the needs of younger men.

Abstract
This review explains the relationship between density functional theory and strongly correlated models using the simplest possible example, the two-site Hubbard model. The relationship to traditional quantum chemistry is included. Even in this elementary example, where the exact ground-state energy and site occupations can be found analytically, there is much to be explained in terms of the underlying logic and aims of density functional theory. Although the usual solution is analytic, the density functional is given only implicitly. We overcome this difficulty using the Levy-Lieb construction to create a parametrization of the exact function with negligible errors. The symmetric case is most commonly studied, but we find a rich variation in behavior by including asymmetry, as strong correlation physics vies with charge-transfer effects. We explore the behavior of the gap and the many-body Green's function, demonstrating the 'failure' of the Kohn-Sham (KS) method to reproduce the fundamental gap. We perform benchmark calculations of the occupation and components of the KS potentials, the correlation kinetic energies, and the adiabatic connection. We test several approximate functionals (restricted and unrestricted Hartree-Fock and Bethe ansatz local density approximation) to show their successes and limitations. We also discuss and illustrate the concept of the derivative discontinuity. Useful appendices include analytic expressions for density functional energy components, several limits of the exact functional (weak- and strong-coupling, symmetric and asymmetric), various adiabatic connection results, proofs of exact conditions for this model, and the origin of the Hubbard model from a minimal basis model for stretched H2.

Abstract
Sucralose avoiding rats detect a bitter-like taste quality in concentrations of sucralose that are strongly preferred over water by sucralose preferring rats. Here, we investigated whether sucralose preferrers (SP) also detect a bitter-like quality in sucralose that may be masked by an increased perception of sucralose's sweet-like quality. A microstructural analysis of sucralose intake revealed that, at concentrations they avoided in preference tests, sucralose avoiders (SA) consumed smaller and fewer bouts of sucralose than SP. Interestingly, the concentration-dependent increase in sucralose preference in SP was not associated with larger bouts or increased lick rate, two measures that are expected to increase with increasing perceived sweetness. This suggests that SP can detect an aversive quality in sucralose, but this perception of a presumably bitter-like quality may be masked by increased salience of a sweet-like quality that sustains high levels of intake in SP. Further evidence for increased sweet-taste perception in SP, relative to SA, was obtained in a second study in which SP consumed more of a palatable sweet-milk diet than SA. These are the first data to suggest that SP are not blind to the bitter-like quality in sucralose, and that there may be differences in sweet-taste perception between SP and SA.

Abstract
New protein parameters are reported for the all-atom empirical energy function in the CHARMM program. The parameter evaluation was based on a self-consistent approach designed to achieve a balance between the internal (bonding) and interaction (nonbonding) terms of the force field and among the solvent-solvent, solvent-solute, and solute-solute interactions. Optimization of the internal parameters used experimental gas-phase geometries, vibrational spectra, and torsional energy surfaces supplemented with ab initio results. The peptide backbone bonding parameters were optimized with respect to data for N-methylacetamide and the alanine dipeptide. The interaction parameters, particularly the atomic charges, were determined by fitting ab initio interaction energies and geometries of complexes between water and model compounds that represented the backbone and the various side chains. In addition, dipole moments, experimental heats and free energies of vaporization, solvation and sublimation, molecular volumes, and crystal pressures and structures were used in the optimization. The resulting protein parameters were tested by applying them to noncyclic tripeptide crystals, cyclic peptide crystals, and the proteins crambin, bovine pancreatic trypsin inhibitor, and carbonmonoxy myoglobin in vacuo and in crystals. A detailed analysis of the relationship between the alanine dipeptide potential energy surface and calculated protein φ, χ angles was made and used in optimizing the peptide group torsional parameters. The results demonstrate that use of ab initio structural and energetic data by themselves are not sufficient to obtain an adequate backbone representation for peptides and proteins in solution and in crystals. Extensive comparisons between molecular dynamics simulations and experimental data for polypeptides and proteins were performed for both structural and dynamic properties. Energy minimization and dynamics simulations for crystals demonstrate that the latter are needed to obtain meaningful comparisons with experimental crystal structures. The presented parameters, in combination with the previously published CHARMM all-atom parameters for nucleic acids and lipids, provide a consistent set for condensed-phase simulations of a wide variety of molecules of biological interest.

Abstract
The federal government has established rapid identification, linkage, and engagement in medical care of HIV-positive individuals as a high priority. Outreach workers and other linkage coordinators are identified as key personnel in implementing this policy. Young racial/ethnic minority men who have sex with men (MSM) have relatively high and growing rates of HIV infection and would benefit from the services of outreach workers. In this article, we describe the characteristics of outreach workers employed by eight demonstration sites participating in the federal Special Projects of National Significance (SPNS) Young MSM of Color Initiative, the linkage and retention models used by the sites, and the number of outreach/ linkage contacts and individuals referred to HIV care. We summarize rates of retention of outreach workers in employment, factors associated with worker turnover, and costs associated with their replacement. We also summarize the experiences of demonstration sites in employing and retaining outreach workers and improving their performance. The insights of outreach workers are reported regarding the challenges they experienced while conducting outreach. Recommendations from demonstration site project managers and outreach workers are offered to improve workplace performance and job retention. Outreach and retention strategies, as well as lessons learned in employing outreach workers, are useful to programs serving young racial/ethnic minority MSM and other HIV-positive groups.

Abstract
This is a qualitative study documenting the experiences of fathers who participated in the Helping Our Toddlers, Developing Our Children's Skills (HOT DOCS) behavioral parent training (BPT) series and later agreed to participate in a focus group. Focus groups methodology was used to capture the voices and perspectives of fathers regarding the benefits and barriers to their participation in BPT. The focus group interviews were conducted in both English and in Spanish, with three cohorts of male caregivers who were participants in HOT DOCS from 2006 to 2008. An analysis of their responses coded from transcripts of the focus groups identified five major themes, which are discussed as (a) motivational factors for joining BPT, (b) fathers' experiences with BPT, (c) barriers regarding fathers' participation, (d) changes in parenting as a result of BPT, and (e) perceived changes in children's behavior as a result of BPT. In addition, recommendations for improvement of BPT are presented. This research may be helpful in improving efforts to engage male caregivers in BPT and thereby reduce children's challenging behavior problems and improve program outcomes.

Abstract
The quasilinear bands in the topologically trivial skutterudite insulator CoSb(3) are studied under adiabatic, symmetry-conserving displacement of the Sb sublattice. In this cubic, time-reversal and inversion symmetric system, a transition from trivial insulator to topological point Fermi surface system occurs through a critical point in which massless (Dirac) bands appear, and moreover are degenerate with massive bands. Spin-orbit coupling, while small due to the type of band character, coupled with tetragonal strain opens the gap required to give the topological insulator. The mineral skutterudite (CoSb(3)) is very near the critical point in its natural state.

Abstract
Young men who have sex with men (YMSM) of color are at particularly increased risk for HIV infection compared to white MSM. National data highlight the need to link YMSM of color to care to improve their overall health and stem further infections, yet, there is limited data on interventions and clinical outcomes focused on engaging and retaining youth, specifically HIV-infected YMSM of color in care. To address the medical care needs of this underserved population, in 2005, the Health Research and Services Administration (HRSA) created the YMSM of Color Initiative. Utilizing a social marketing campaign targeting youth and members of their sexual and social networks, testing and outreach on college campuses and within the broader community, and a tightly linked medical-social support network, we created STYLE (Strength Through Youth Livin' Empowered), a novel intervention that sought to diagnose, engage, and retain HIV-positive black and Latino YMSM in HIV primary care services. Over a 3-year period, 81 men were either newly diagnosed or reengaged in care. Overall, 63% of the cohort was retained in clinical care; defined as attending at least one medical visit every 4 months. Compared to the 3 years prior to STYLE, the odds ratio for whether or not someone attended a clinic visit was 2.58 (95% confidence interval [CI] 1.34-4.98) if enrolled in STYLE. We conclude that compared to a pre-STYLE cohort, STYLE was an effective intervention that increased HIV diagnoses, provided efficient and timely engagement in care for both those newly diagnosed and those who had fallen out of care and improved overall retention.

Abstract
BACKGROUND AND PURPOSE Bone morphogenetic proteins (BMPs) were first identified through their role in inducing bone and cartilage formation, but many other important functions have since been ascribed to BMPs, including dorsoventral patterning, angiogenesis and tissue homeostasis. Using dorsomorphin and LDN193189, selective small molecule inhibitors of BMP signalling, we investigated the role of BMP signalling in early vascular patterning in zebrafish. EXPERIMENTAL APPROACH The effects of dorsomorphin and LDN193189 on vascular endothelial growth factor-a (VEGF) and BMP signalling in developing zebrafish and in human pulmonary artery endothelial cells were determined using confocal microscopy, Western blotting and quantitative PCR. KEY RESULTS We showed that dorsomorphin, similar to the VEGF inhibitor SU5416, strongly inhibits intersegmental vessel formation in zebrafish and that this is due to inhibition of VEGF activation of VEGF receptor 2 (VEGFR2), leading to reduced VEGF-induced phospho-ERK (extracellular regulated kinase) 1/2 and VEGF target gene transcription. These effects occurred at concentrations of dorsomorphin that block BMP signalling. We also showed that LDN193189, an analogue of dorsomorphin, more potently blocks BMP signalling but has no effect on VEGF signalling in zebrafish and does not disrupt early vascular patterning. CONCLUSIONS AND IMPLICATIONS Dorsomorphin inhibits both BMP and VEGF signalling, whereas LDN193189 is a more selective BMP antagonist. Results obtained in cardiovascular studies using dorsomorphin need to be interpreted with caution, and use of LDN193189 would be preferable due to its selectivity. Our data also suggest that BMP signalling is dispensable for early patterning of intersegmental vessels in zebrafish.

Abstract
In phytoplankton of the eastern tropical Pacific Ocean from 25 to 90 percent of the biomass (measured as chlorophyll a) and 20 to 80 percent of the inorganic carbon fixation were attributable to particles that could pass a screen with a 1-micrometer pore diameter. Evidence is presented that these are indeed autotrophic cells and not cell fragments.

Abstract
The Internet is a popular way for people to meet casual sex partners. However, online outreach remains largely unexplored to promote voluntary counseling and testing for HIV. The Student Health Action Coalition's HIV testing program (SHAC-HIV) targets high-risk clients through tailored Internet outreach via chat rooms, social networking sites, and online forums. The SHAC-HIV model also demonstrates that nontraditional testing sites can provide low-cost, client-centered, high-quality services to support increased demand for HIV-testing services. Within the clinic, SHAC-HIV's testing model includes four major components: (a) reliance on a team of well-trained health sciences student volunteers; (b) rapid oral-fluid HIV tests; (c) universal, consent-based testing with client-centered health education and counseling; and (d) coordinated referrals for follow-up testing, treatment, and care. This approach reaches high-risk clients as well as undiagnosed infections. In 2007, there were nine confirmed positive results out of 389 tests, yielding a 2.3% positivity rate. This positivity percentage is higher than any other nontraditional testing site in North Carolina. This article describes the SHAC-HIV outreach and voluntary counseling and testing program with the aim of encouraging adoption of the model by other nontraditional testing sites.

Abstract
Signalling by members of the FGF family is required for induction and maintenance of the mesoderm during amphibian development. One of the downstream effectors of FGF is the SRF-interacting Ets family member Elk-1, which, after phosphorylation by MAP kinase, activates the expression of immediate-early genes. Here, we show that Xenopus Elk-1 is phosphorylated in response to FGF signalling in a dynamic pattern throughout the embryo. Loss of XElk-1 function causes reduced expression of Xbra at neurula stages, followed by a failure to form notochord and muscle and then the partial loss of trunk structures. One of the genes regulated by XElk-1 is XEgr-1, which encodes a zinc finger transcription factor: we show that phosphorylated XElk-1 forms a complex with XSRF that binds to the XEgr-1 promoter. Superficially, Xenopus tropicalis embryos with reduced levels of XEgr-1 resemble those lacking XElk-1, but to our surprise, levels of Xbra are elevated at late gastrula stages in such embryos, and over-expression of XEgr-1 causes the down-regulation of Xbra both in whole embryos and in animal pole regions treated with activin or FGF. In contrast, the myogenic regulatory factor XMyoD is activated by XEgr-1 in a direct manner. We discuss these counterintuitive results in terms of the genetic regulatory network to which XEgr-1 contributes.

Abstract
Mammalian central pattern generators producing rhythmic movements exhibit robust but flexible behavior. However, brainstem network architectures that enable these features are not well understood. Using precise sequential transections through the pons to medulla, it was observed that there was compartmentalization of distinct rhythmogenic mechanisms in the ponto-medullary respiratory network, which has rostro-caudal organization. The eupneic 3-phase respiratory pattern was transformed to a 2-phase and then to a 1-phase pattern as the network was physically reduced. The pons, the retrotrapezoid nucleus and glycine mediated inhibition are all essential for expression of the 3-phase rhythm. The 2-phase rhythm depends on inhibitory interactions (reciprocal) between Bötzinger and pre-Bötzinger complexes, whereas the 1-phase-pattern is generated within the pre-Bötzinger complex and is reliant on the persistent sodium current. In conditions of forced expiration, the RTN region was found to be essential for the expression of abdominal late expiratory activity. However, it is unknown whether the RTN generates or simply relays this activity. Entrained with the central respiratory network is the sympathetic nervous system, which exhibits patterns of discharge coupled with the respiratory cycle (in terms of both gain and phase of coupling) and dysfunctions in this coupling appear to underpin pathological conditions. In conclusion, the respiratory network has rhythmogenic capabilities at multiple levels of network organization, allowing expression of motor patterns specific for various physiological and pathophysiological respiratory behaviors.
