RESUMEN
Both health and the environment are critical public health issues that have a considerable impact on young adults. However, they have different characteristics that influence how messaging is received. In our study, we examine the influence of three personal factors (issue involvement, behavioral change intention, and product use) on young adults' perception of messages for these two public health issues from both first- and third-person perspectives. We found various patterns when comparing the two public health issues, first-person and third-person measures, and the perceived threat and likelihood of contributing to the issues. We also discuss practical implications and suggestions based on our findings.
RESUMEN
Adolescents are sexually assaulted at remarkably high rates. Adolescents are also unique given the specific dynamics of adolescent sexual assault, their current stage in human development, their limited legal standing and rights, and their experiences navigating postassault services and resources. While literature exists within each of these domains, it is somewhat disconnected and overlooks how adolescents are often relegated to the margins in research and practice. The purpose of this integrative review is to (1) provide a more complete understanding of adolescent sexual assault and survivors' nuanced needs; (2) frame adolescent survivors as a too-often-overlooked oppressed group that researchers and responders must consider and center in their work, lest contribute to their further marginalization; and (3) inspire and orient social justice-minded scholar activists to various action steps to take to center and prioritize adolescents in research and practice. Through our intersectional feminist approach, we offer specific action steps for social justice-minded scholar activists to recenter adolescents in their research and practice.

The United Kingdom (UK) and Europe have seen successive outbreaks of H5N1 clade 2.3.4.4b high-pathogenicity avian influenza virus (HPAIV) since 2020 peaking in the autumn/winter periods. During the 2021/22 season, a mass die-off event of Svalbard Barnacle Geese (Branta leucopsis) was observed on the Solway Firth, a body of water on the west coast border between England and Scotland. This area is used annually by Barnacle Geese to over-winter, before returning to Svalbard to breed. Following initial identification of HPAIV in a Barnacle Goose on 8 November 2021, up to 32% of the total Barnacle Goose population may have succumbed to disease by the end of March 2022, along with other wild bird species in the area. Potential adaptation of the HPAIV to the Barnacle Goose population within this event was evaluated. Whole-genome sequencing of thirty-three HPAIV isolates from wild bird species demonstrated that there had been two distinct incursions of the virus, but the two viruses had remained genetically stable within the population, whilst viruses from infected wild birds were closely related to those from poultry cases occurring in the same region. Analysis of sera from the following year demonstrated that a high percentage (76%) of returning birds had developed antibodies to H5 AIV. This study demonstrates genetic stability of this strain of HPAIV in wild Anseriformes, and that, at the population scale, whilst there is a significant impact on survival, a high proportion of birds recover following infection.
RESUMEN
Laser wakefield accelerators (LWFAs) have electric fields that are orders of magnitude larger than those of conventional accelerators, promising an attractive, small-scale alternative for next-generation light sources and lepton colliders. The maximum energy gain in a single-stage LWFA is limited by dephasing, which occurs when the trapped particles outrun the accelerating phase of the wakefield. Here, we demonstrate that a single space-time structured laser pulse can be used for ionization injection and electron acceleration over many dephasing lengths in the bubble regime. Simulations of a dephasingless laser wakefield accelerator driven by a 6.2-J laser pulse show 25 pC of injected charge accelerated over 20 dephasing lengths (1.3 cm) to a maximum energy of 2.1 GeV. The space-time structured laser pulse features an ultrashort, programmable-trajectory focus. Accelerating the focus, reducing the focused spot-size variation, and mitigating unwanted self-focusing stabilize the electron acceleration, which improves beam quality and leads to projected energy gains of 125 GeV in a single, sub-meter stage driven by a 500-J pulse.
RESUMEN
Bisthienoazepinedione (BTA) has been reported for constructing high-performing p-type conjugated polymers in organic electronics, but the ring extended version of BTA is not well explored. In this work, we report a new synthesis of a key building block to the ring expanded electron-deficient pentacyclic azepinedione (BTTA). Three copolymers of BTAA with benzodithiophene substituted by different side chains are prepared. These polymers exhibit similar energy levels and optical absorption in solution and solid state, while significant differences are revealed in their film morphologies and behavior in transistor and photovoltaic devices. The best-performing polymers in transistor devices contained alkylthienyl side chains on the BDT unit (pBDT-BTTA-2 and pBDT-BTTA-3) and demonstrated maximum saturation hole mobilities of 0.027 and 0.017 cm2 V-1 s-1. Blends of these polymers with PC71BM exhibited a best photovoltaic efficiency of 6.78% for pBDT-BTTA-3-based devices. Changing to a low band gap non-fullerene acceptor (BTP-eC9) resulted in improved efficiency of up to 13.5%. Our results are among the best device performances for BTA and BTTA-based p-type polymers and highlight the versatile applications of this electron-deficient BTTA unit.
RESUMEN
INTRODUCTION: This study explores the assessments of mental health clinicians working with suicidal patients who requested access to medical assistance in dying (MAiD). METHODS: A sample of convenience completed an online questionnaire about their experiences with suicidal patients. Respondents described their encounters with 227 suicidal patients: 44 requested access to MAiD, and 183 did not. Data were analyzed using chi-squared and simple t-test to identify differences between the respondents' descriptions of the two groups. RESULTS: Results noted differences between patients who experience suicide ideation and request MAiD (SPM), and those who experience suicide ideation and do not (SP). Overall, the SPM group was older, more physical health concerns, chronic pain, existential distress, and less hope. Many had experienced several episodes of mental health care and medication trials, though unlike the SP group, they had a split between accessing a little care and a lot of care. They also engaged in less suicide planning, and some had no history of suicide attempts. CONCLUSION: It is important that mental health clinicians learn to differentiate between MAiD requests due to an ongoing and irremediable mental disorder, and MAiD requests in response to circumscribed psychological suffering that could be relieved via a change in circumstances and/or access to different treatment options amenable to the patient.
RESUMEN
Nicotine is an addictive drug whose popularity has recently increased, particularly among adolescents, because of the availability of electronic nicotine devices (i.e., "vaping") and nicotine e-liquids containing additives with rich chemosensory properties. Some efforts to understand the role of these additives in nicotine reward suggest that they increase nicotine reward and reinforcement, but the sensory contributions of additives, especially in their vapor forms, are largely untested. Here, to better understand how a fruit-flavored (i.e., strawberry) additive influences nicotine reward and aversion, we used a conditioned place preference (CPP) procedure in which nicotine and a strawberry additive were delivered as a vapor to male and female adolescent mice. We found that nicotine vapor alone can lead to a dose-dependent CPP when using a biased design. The strawberry additive did not produce CPP on its own, and we did not observe an effect of the strawberry additive on nicotine vapor-induced reward. Nevertheless, mice exposed to nicotine plus strawberry additive vapor had higher plasma cotinine concentrations, which did not appear to reflect altered nicotine metabolism. Instead, by directly measuring vapor sampling through respiration monitoring, we uncovered an increase in the amount of sniffing toward strawberry-containing nicotine vapor compared with nicotine vapor alone. Together these data indicate that chemosensory-rich e-liquid additives may enhance the perceived sensory profile of nicotine vapors rather than the reward value per se, which leads to overall increased nicotine exposure.

Nicotine is the principal psychoactive component in tobacco that drives addiction through its action on neuronal nicotinic acetylcholine receptors (nAChR). The nicotinic receptor gene CHRNA5, which encodes the α5 subunit, is associated with nicotine use and dependence. In humans, the CHRNA5 missense variant rs16969968 (G > A) is associated with increased risk for nicotine dependence and other smoking-related phenotypes. In rodents, α5-containing nAChRs in dopamine (DA) neurons within the ventral tegmental area (VTA) powerfully modulate nicotine reward and reinforcement. Although the neuroadaptations caused by long-term nicotine exposure are being actively delineated at both the synaptic and behavioral levels, the contribution of α5-containing nAChRs to the cellular adaptations associated with long-term nicotine exposure remain largely unknown. To gain insight into the mechanisms behind the influence of α5-containing nAChRs and the rs16969968 polymorphism on nicotine use and dependence, we used electrophysiological approaches to examine changes in nAChR function arising in VTA neurons during chronic nicotine exposure and multiple stages of nicotine withdrawal. Our results demonstrate that CHRNA5 mutation leads to profound changes in VTA nAChR function at baseline, during chronic nicotine exposure, and during short-term and prolonged withdrawal. Whereas nAChR function was suppressed in DA neurons from WT mice undergoing withdrawal relative to drug-naïve or nicotine-drinking mice, α5-null mice exhibited an increase in nAChR function during nicotine exposure that persisted throughout 5-10 weeks of withdrawal. Re-expressing the hypofunctional rs16969968 CHRNA5 variant in α5-null VTA DA neurons did not rescue the phenotype, with α5-SNP neurons displaying a similar increased response to ACh during nicotine exposure and early stages of withdrawal. These results demonstrate the importance of VTA α5-nAChRs in the response to nicotine and implicate them in the time course of withdrawal.

Community psychologists (CPs) are committed to value-based praxis, an interdisciplinary orientation, and an ecological approach to community collaboration in pursuit of social justice and liberation. Because no setting is immune to the impacts of the intersecting systems of oppression in which we are embedded, CPs end up working in a wide array of settings, and often as the only CP in the setting. This dynamic-operating as a "lone" CP-may be rewarding as the CP is able to provide unique value at work, or may present specific challenges, particularly if the CP's sense of community or mattering is compromised. We interviewed n = 31 lone CP to explore their work experiences, including the benefits, challenges, and what they need to thrive in their current setting. Findings reveal a wide array of experiences among CPs, related to their community psychology, and other identities. Participants consistently discussed the important role of values in their decision-making and experiences at work, and provide specific recommendations as to how the Society for Community Research and Action (SCRA) can ensure all CPs across all settings can thrive. This includes providing more tangible and relational support, changing SCRA's culture and priorities, and improving community psychology undergraduate and graduate training.

While rape crisis center (RCC) advocacy is generally regarded as valuable, there are no prior systematic reviews of the advocacy literature. This review examined RCC advocacy service provision, perceptions and impact of advocacy, and challenges and facilitators to effective service provision. Databases related to health and social sciences were searched including Academic Search Complete, PsychINFO, PubMed, CINAHL, ProQuest, Science Direct, OAlster, WorldCat, and MEDLINE. Empirical articles written in English that examined RCC advocacy service provision and/or impact in the US were included. The researchers reviewed abstracts and titles, and then full texts. Forty-five articles met criteria, were summarized, and double checked. Findings demonstrate advocacy is multi-faceted, beneficial, and challenging. Advocates work directly with survivors and interact with other responders on behalf of survivors. Specifically, advocates provide emotional support, safety plan, support survivors in making decisions, and assist them in navigating other systems. While advocates are generally regarded positively by survivors and responders, some responders have concerns about advocates. In addition, advocates sometimes report victim-blaming and being ill-equipped to meet survivors' needs. Finally, advocates face specific challenges in their work with survivors and responders. Future research using diverse methodological approaches is needed to understand advocacy utilization and reach; survivors' perceptions of advocacy; marginalized survivors' experiences; connections between specific services, implementation, and outcomes; and effective strategies for advocates' interactions with other responders. Additional resources to help advocates serve all survivors effectively and equitably; to support evaluator-practitioner partnerships; and to share unpublished data on advocacy may help contribute to improvements in advocacy practice.

Adolescents experience alarmingly high rates of sexual violence, higher than any other age-group. This is concerning as sexual violence can have detrimental effects on teens' personal and relational well-being, causing long-term consequences for the survivor. Still, adolescents are hesitant to report the assault or seek out services and resources. When an adolescent survivor does seek out services, they may interact with a provider who is a mandatory reporter. This scoping review sought to synthesize the current U.S.-based research on the role, challenges, and impact of mandatory reporting (MR) in the context of adolescent sexual assault. Database searches using key words related to MR, sexual assault, and adolescence identified 29 peer-reviewed articles. However, none of these articles reported on empirical investigations of the phenomenon of interest and instead consisted of case studies, commentaries, and position papers. The scoping review was expanded to provide a lay of the land of what we know about the intersection of adolescent sexual assault and MR. Results of the review indicate that though implemented broadly, MR policies vary between individuals, organizations, and states and have historically been challenging to implement due to this variation, conflicts with other laws, tension between these policies and providers' values, and other factors. Based on the available literature, the impact of MR in the context of adolescent sexual assault is unknown. There is a critical need for research and evaluation on the implementation and impact of MR policies, especially in the context of adolescents and sexual violence.

BACKGROUND: The British Antarctic bases offer a semiclosed environment for assessing the transmission and persistence of seasonal respiratory viruses. METHODS: Weekly swabbing was performed for respiratory pathogen surveillance (including SARS-CoV-2), at 2 British Antarctic Survey bases, during 2020: King Edward Point (KEP, 30 June to 29 September, 9 participants, 124 swabs) and Rothera (9 May to 6 June, 27 participants, 127 swabs). Symptom questionnaires were collected for any newly symptomatic cases that presented during this weekly swabbing period. RESULTS: At KEP, swabs tested positive for non-SARS-CoV-2 seasonal coronavirus (2), adenovirus (1), parainfluenza 3 (1), and respiratory syncytial virus B (1). At Rothera, swabs tested positive for non-SARS-CoV-2 seasonal coronavirus (3), adenovirus (2), parainfluenza 4 (1), and human metapneumovirus (1). All bacterial agents identified were considered to be colonizers and not pathogenic. CONCLUSIONS: At KEP, the timeline indicated that the parainfluenza 3 and adenovirus infections could have been linked to some of the symptomatic cases that presented. For the other viruses, the only other possible sources were the visiting ship crew members. At Rothera, the single symptomatic case presented too early for this to be linked to the subsequent viral detections, and the only other possible source could have been a single nonparticipating staff member.

Sexual Assault Nurse Examiners (SANEs) provide expert, comprehensive medical forensic care to patients who present for services following a sexual assault. Because SANEs are not consistently available, telehealth technology is being explored as a means to provide access to this expert care (i.e., teleSANE). During the COVID-19 pandemic, teleSANE offered additional potential benefits by reducing the length of time spent and number of providers in patient exam rooms, the need for personal protective equipment that was in high demand and short supply, and provider anxiety related to providing in-person care. In the summer of 2020, the Massachusetts SANE program rapidly and temporarily converted five hospitals from in-person SANE care to teleSANE. An evaluation team interviewed 23 providers using a rapid research and evaluation methods approach to assess the temporary model and inform the future of SANE care. Evaluation findings reveal it is possible to rapidly and temporarily convert hospitals from in-person to teleSANE care in a time of broad uncertainty, and that such a change requires intensive and thoughtful planning; a shared commitment to being supportive, flexible, and responsive; and specific experience and expertise. Considerations for communities exploring how best to ensure consistent, equitable access to SANEs are discussed.

Alcohol and nicotine are commonly used during adolescence, establishing long-lasting neuroplastic alterations that influence subsequent drug use and abuse. Drinking- and smoking-related traits have been extensively associated with variation in CHRNA5 - the gene that encodes the α5 subunit of neuronal nicotinic acetylcholine receptors (nAChRs). The single nucleotide polymorphism (SNP) rs16969968 in CHRNA5 encodes an amino acid substitution (D398N) that alters the function and pharmacokinetics of α5-containing nAChR. When expressed in rodents, this variant results in increased ethanol and nicotine operant self-administration. How disruption of α5-containing nAChRs influences adolescent ethanol and nicotine intake, and how it modulates interactions between these drugs has not been previously explored. In the present study, we examined volitional ethanol and nicotine consumption in adolescent mice (post-natal day 30-43) of both sexes with mutated (SNP) or lacking (KO) the α5 nAChR subunit. The effect of adolescent alcohol or nicotine exposure on home cage consumption of the opposite drug in adulthood and its modulation by Chrna5 mutation and sex were examined. During adolescence, we found that α5 nAChR disruption increases nicotine intake in mice of both sexes, but the effect on alcohol intake was only observed in females. The sex-specific increase in alcohol consumption in α5 SNP and KO was replicated in adulthood. The effect of adolescent alcohol or nicotine exposure on subsequent intake of the opposite drug in adulthood is modulated by sex and Chrna5 mutation. These observations suggest sex differences in the genetic architecture of alcohol dependence, and modulators of alcohol and nicotine interactions.

Community psychology has long valued reflexive praxis as a critical part advancing our research and action. In this Virtual Special Issue (VSI), we, a group of community psychologists and gender-based violence (GBV) researchers at many different points in our careers, reflected on GBV publications that have appeared in AJCP. We examine the ways in which community psychology broadly and articles in AJCP more specifically have conceptualized GBV as a sociocultural issue, how GBV intersects with other oppressions and forms of violence, the tension when systems that aspire to support survivors are inequitable and focused on ameliorative change, and the importance of interventions being locally informed and locally driven. By highlighting selected GBV-focused articles published in AJCP, this VSI discusses (a) understanding and transforming culture via robust research and local partnerships, (b) targeting effective interventions for survivors, (c) invoking systems and targeting change in institutional environments, and (d) making connections between local efforts and broader social movements. To continue to move forward, we conclude we must reflect, embrace methodological plurality, partner, and push for structural change. Reflective questions regarding research and action are offered, to address gender-based violence.

Rationale: Methylation integrates factors present at birth and modifiable across the lifespan that can influence pulmonary function. Studies are limited in scope and replication. Objectives: To conduct large-scale epigenome-wide meta-analyses of blood DNA methylation and pulmonary function. Methods: Twelve cohorts analyzed associations of methylation at cytosine-phosphate-guanine probes (CpGs), using Illumina 450K or EPIC/850K arrays, with FEV1, FVC, and FEV1/FVC. We performed multiancestry epigenome-wide meta-analyses (total of 17,503 individuals; 14,761 European, 2,549 African, and 193 Hispanic/Latino ancestries) and interpreted results using integrative epigenomics. Measurements and Main Results: We identified 1,267 CpGs (1,042 genes) differentially methylated (false discovery rate, <0.025) in relation to FEV1, FVC, or FEV1/FVC, including 1,240 novel and 73 also related to chronic obstructive pulmonary disease (1,787 cases). We found 294 CpGs unique to European or African ancestry and 395 CpGs unique to never or ever smokers. The majority of significant CpGs correlated with nearby gene expression in blood. Findings were enriched in key regulatory elements for gene function, including accessible chromatin elements, in both blood and lung. Sixty-nine implicated genes are targets of investigational or approved drugs. One example novel gene highlighted by integrative epigenomic and druggable target analysis is TNFRSF4. Mendelian randomization and colocalization analyses suggest that epigenome-wide association study signals capture causal regulatory genomic loci. Conclusions: We identified numerous novel loci differentially methylated in relation to pulmonary function; few were detected in large genome-wide association studies. Integrative analyses highlight functional relevance and potential therapeutic targets. This comprehensive discovery of potentially modifiable, novel lung function loci expands knowledge gained from genetic studies, providing insights into lung pathogenesis.

Despite years of standard treatments, a Marine veteran and former firefighter, disabled due to severe post-traumatic stress disorder (PTSD), worsened over ten weeks while receiving usual care. Bilateral injection of 10 mL of 5% dextrose in water using a 30-gauge needle just under the sternocleidomastoid muscle was performed at weeks 10, 12, 14, 16, and 18. Clinically important improvements were observed by 18 weeks on a 0-10 anxiety rating scale (57%), the PTSD checklist for civilians (41%), EuroQol overall quality of life scale (40%), and the Hospital Anxiety and Depression Scale (28%). Improvements were stable through 22 weeks. He reported symptomatic benefit on anxiety within 20 minutes of injection, suggesting a neurogenic mechanism, potentially related to a therapeutic effect on the nearby sympathetic trunk/superior sympathetic ganglion. Advantages of this procedure over stellate ganglion blockade include its safety (no lidocaine), bilateral treatment option, simplicity, and comfort.
RESUMEN
BACKGROUND: This study evaluated whether sexual health services (SHS) across the UK could meet the Faculty of Sexual and Reproductive Health (FSRH) standard for access by being able to offer an appointment for a long-acting reversible contraception (LARC) fitting within 2 weeks of initial contact. METHODS: SHSs offering LARCs were identified using the British Association for Sexual Health and HIV (BASHH) clinic database. During October 2020, all clinics open for more than 1 day a week were contacted by telephone. The researcher posed as a 20-year-old woman in a regular heterosexual relationship who was using condoms and requesting a contraceptive implant. Data collected included the time to wait to appointment and whether clinics offered bridging methods of contraception during any delay in appointment. It was also noted whether a local COVID-19 restriction was in place at the time of the call. The information collected was coded, and data was analysed using chi-square tests in SPSSv27. RESULTS: Of the 218 contactable clinics, 51.4% (n = 112) of clinics offered the patient an appointment within two weeks, and 66.1% (n = 144) of clinics could offer appointments within four weeks. 7.3% (n = 16) of clinics offered the patient adjunct bridging oral contraception until the time of appointment. Comparing the devolved nations, 11/17 (64.7%) clinics in Scotland, 8/13 (61.5%) clinics in Wales, 0/4 (0.0%) clinics in Northern Ireland and 93/182 (51.1%) clinics in England offered an appointment within two weeks with significant regional variation across England (p = .005). No statistically significant difference was demonstrated in access between clinics with or without high-level COVID-19 restrictions (p = .056). CONCLUSION: The 2-week standard was met in just over half of the occasions, with significant variation across regions across the UK. The development of a national target for access may improve access to LARCs.

ABSTRACT: Many communities across the country are developing, implementing, or already operating programs that provide patients with access to sexual assault nurse examiner (SANE) expertise and care through telehealth technology (e.g., teleSANE or teleSAFE). The speed at which teleSANE programs are proliferating is outpacing the available research and evaluation to inform key decisions on program development and implementation. During the height of the COVID-19 pandemic, the Massachusetts Department of Public Health SANE Program and its National TeleNursing Center decided to rapidly and temporarily convert a set of hospitals from providing in-person SANE care to remote teleSANE care. Several specific changes were made to this program's established teleSANE model for the rapid, temporary conversion. This article reports on findings from an evaluation of the temporary TeleSANE model that provide insight into key decisions that must be made in the development and implementation of teleSANE program features. Communities considering developing or already operating a teleSANE program should be intentional in making program goals, purposes, and values explicit as well as develop their program accordingly.
