An open-air method for the transition metal-free direct amination of nitro(hetero)arenes by anilines is disclosed. In this methodology, an aromatic C-H bond is substituted via oxidative nucleophilic aromatic substitution of hydrogen (ONSH). Density functional theory calculations and mechanistic studies support a dianion pathway with oxidation by molecular oxygen as the rate-limiting step.

Early geography in the United States has a rich history, though not always understood or acknowledged. One American geographer in the pre-Humboldt era who has been largely overlooked is Columbia University's John Daniel Gross, who has been described as "arguably the first American professional geographer." The purpose of this research is to shed more light on this eighteenth-century geographer. Evidence suggests that, unlike some other prominent geographers of their day who subsequently became relegated to obscurity, Gross displayed neither controversial views nor a personality that conflicted with more powerful contemporary rivals. Instead, although geographical, synchronistic, epistemological, and personal attributes make it seem likely that his work created a bridge to the new geography of Alexander von Humboldt and Carl Ritter, his work and reputation appear to have been overshadowed by that of the "new geography." The demise of Ivy League geography appears to have cemented his lost legacy. [ABSTRACT FROM AUTHOR]

- Abstract
This book provides a foundational look at social virtual worlds from the geographer's perspective. How can the geographer's craft be applied to social virtual worlds? This question is addressed through careful analysis of what social virtual worlds are, how interest in these worlds has waxed and waned during the twenty-first century, and the meaning of their concocted spaces. Examining one of the key features of the social virtual world, the avatar, the book focuses on its user's motivations and identity choices. The book draws on the geographical understanding of place to examine where avatars live, work, and roam, and describes how virtual-world places resemble and diverge from actual-world places. A mixed-methods survey conducted in Second Life adds additional breadth to the discussion, whilst a series of vignettes gives extra life to the subject matter. This original exploration of the content and meaning of social virtual worlds is an essential resource for geographers, and for anyone interested in the virtual world experience.

We conducted a prospective environmental surveillance study to investigate the air, surface, dust, and water contamination of a room occupied by a patient infected with mpox virus (MPXV) at various stages of the illness. The patient tested positive for MPXV from a throat swab and skin lesions. Environmental sampling was conducted in a negative pressure room with 12 unidirectional high efficiency particulate air filter (HEPA) air changes per hour and daily cleaning of the surfaces. A total of 179 environmental samples were collected on days 7, 8, 13, and 21 of illness. Among the days of sampling, air, surface, and dust contamination showed the highest contamination rates on day 7 and 8 of illness, with a gradual decline to the lowest contamination level by day 21. Viable MPXV was isolated from surfaces and dust samples and no viable virus was isolated from the air and water samples.

Parkinson’s disease (PD) is a progressive neurodegenerative disorder that leads to numerous impairments in motor function that compromise the ability to perform activities of daily living. Practical and effective adjunct therapies are needed to complement current treatment approaches in PD. Transcranial direct current stimulation applied to the cerebellum (c-tDCS) can increase motor skill in young and older adults. Because the cerebellum is involved in PD pathology, c-tDCS application during motor practice could potentially enhance motor skill in PD. The primary purpose was to examine the influence of c-tDCS on motor skill acquisition in a complex, visuomotor isometric precision grip task (PGT) in PD in the OFF-medication state. The secondary purpose was to determine the influence of c-tDCS on transfer of motor skill in PD. The study utilized a double-blind, SHAM-controlled, within-subjects design. A total of 16 participants completed a c-tDCS condition and a SHAM condition in two experimental sessions separated by a 7-day washout period. Each session involved practice of the PGT concurrent with either c-tDCS or SHAM. Additionally, motor transfer tasks were quantified before and after the practice and stimulation period. The force error in the PGT was not significantly different between the c-tDCS and SHAM conditions. Similarly, transfer task performance was not significantly different between the c-tDCS and SHAM conditions. These findings indicate that a single session of c-tDCS does not elicit acute improvements in motor skill acquisition or transfer in hand and arm tasks in PD while participants are off medications.

Introduction: The potential for coordinated, multidisciplinary telehealth to help connect people with Parkinson disease (PD) in rural areas to PD specialists is crucial in optimizing care. Therefore, this study aimed to test the feasibility, safety, and signal of efficacy of a coordinated telehealth program, consisting of speech therapy, physiotherapy, and pharmaceutical care, for people with PD living in some rural US communities. Methods: Fifteen individuals with PD living in rural Wyoming and Nevada, USA, participated in this single-cohort, 8-week pilot study. Participants were assessed before and after 8 weeks of coordinated, one-on-one telehealth using the following outcomes: (1) feasibility: session attendance and withdrawal rate; (2) safety: adverse events; and (3) signal of efficacy: Communication Effectiveness Survey, acoustic data (intensity, duration, work (intensity times duration)), Parkinson's Fatigue Scale, 30 second Sit-to-Stand test, Parkinson's Disease Questionnaire - 39, Movement Disorder Society Unified Parkinson's Disease Rating Scale - Part III, and medication adherence. Results: Average attendance was greater than 85% for all participants. There were no serious adverse events and only nine minor events during treatment sessions (0.9% of all treatment sessions had a participant report of an adverse event); all nine cases resolved without medical attention. Although 14 of 16 outcomes had effect sizes trending in the direction of improvement, only two were statistically significant using non-parametric analyses: 30 second Sit-to-Stand (pre-test median=11.0 (interquartile range (IQR)=6.0); post-test median=12.0 (IQR=3.0) and acoustic data work (pre-test median=756.0 dB s (IQR=198.4); post-test median=876.3 dB s (IQR=455.5), p

- Abstract
Background: Promising evidence supports the effectiveness of edutainment interventions in shifting norms to prevent violence against women and girls and other harmful practices, yet further research into mechanisms and pathways of impact is needed to inform intervention development, delivery and scale-up. This exploratory qualitative evaluation examined the feasibility and indications of change in attitudes, beliefs, norms and behaviours following the broadcast of a radio drama aired to prevent age-disparate transactional sex in Kigoma, Tanzania., Methods: Over seven weeks, six episodes were broadcast on local radio weekly, between November and December 2021 in Kigoma, targeting adolescent girls (aged 13-15 years) and their caregivers. Reflection sessions were conducted twice a week with 70 girls across seven schools, supplemented by after-school Girls' Club listening sessions for a subgroup of 30 girls. We conducted seven before and after focus group discussions, five with girls (n = 50), one with men caregivers (n = 9) and one with women caregivers (n = 9) and analysed them using thematic and framework analysis approaches., Results: Overall, we found that while girls exhibited significant engagement with the drama, caregiver participation, particularly among men, was low. Thus, no clear changes were detected in men. We did not find any differences in impact based on listening sessions' attendance vs. home listening. We detected positive changes among girls and women in four thematic areas after listening to the drama: (1) participant's increasingly challenged perceptions about what kinds of girls and men take part in age-disparate transactional sex, what can be exchanged, and men's motivations for engaging; (2) there was a shift from attributing blame for age-disparate transactional sex relationships from girls to men; (3) girl's reported increased agency and confidence to avoid age-disparate transactional sex relationships; and (4) we found a heightened sense of responsibility and recognition for the role of parents, peers and community members in preventing age-disparate transactional sex., Conclusions: These findings highlight the need for further implementation research to explore ways to effectively engage men. They also underscore the potential of engaging, evidence-based edutainment interventions in fostering spontaneous critical reflection about complex behaviours such as age-disparate transactional sex, and diffusing key messages among target populations without the use of organised diffusion activities., (© 2024.

27. How do extreme weather events contribute to violence against children?

- Abstract
Background: Only recently have research and policy begun to shine a light on the magnifying effects of EWEs (Extreme Weather Events) on children's exposure to violence. However, the links between EWEs and VAC (Violence against Children) remain under-theorised, poorly understood and often unacknowledged in policy and practice., Objective: Identify, synthesize and analyse available evidence on the central characteristics and factors influencing the relationship between VAC and EWEs., Methods: We conducted an extensive scoping review of the literature (academic and grey) to identify existing research and gaps in knowledge. Using flexible and iteratively developed search terms enabled us to identify direct violence - physical, sexual and emotional - and structural violence, rooted in inequitable and unjust systems and institutions., Results: The relationship between VAC and EWEs is linked to gender; climate-induced mobility or immobility; child labour; and health. We found that VAC can intensify during EWEs, but the nature of this relationship is contextually specific. The relationship between VAC and EWEs is rooted in historical injustices, global systems and structures, and therefore disproportionately affects those living in poverty., Conclusion: Studies have uncovered how increasing social, economic and emotional pressures following EWEs increase children's violence risk exposure. This may occur in their homes or in relief shelters. The violence may involve peers, or forms of hazardous labour that young people are compelled into because of the sudden need for families to rebuild or help make ends meet. More knowledge is needed to inform integrated, context-specific and culturally sensitive plans to better protect children from the consequences of EWEs., (Copyright © 2024 The Author(s).

- Abstract
Background: Nirmatrelvir/ritonavir (N/R) reduces severe outcomes from coronavirus disease 2019 (COVID-19); however, rebound after treatment has been reported. We compared symptom and viral dynamics in individuals with COVID-19 who completed N/R treatment and similar untreated individuals., Methods: We identified symptomatic participants who tested severe acute respiratory syndrome coronavirus 2-positive and were N/R eligible from a COVID-19 household transmission study. Index cases from ambulatory settings and their households contacts were enrolled. We collected daily symptoms, medication use, and respiratory specimens for quantitative polymerase chain reaction for 10 days during March 2022-May 2023. Participants who completed N/R treatment (treated) were propensity score matched to untreated participants. We compared symptom rebound, viral load (VL) rebound, average daily symptoms, and average daily VL by treatment status measured after N/R treatment completion or 7 days after symptom onset if untreated., Results: Treated (n = 130) and untreated participants (n = 241) had similar baseline characteristics. After treatment completion, treated participants had greater occurrence of symptom rebound (32% vs 20%; P = .009) and VL rebound (27% vs 7%; P < .001). Average daily symptoms were lower among treated participants without symptom rebound (1.0 vs 1.6; P < .01) but not statistically lower with symptom rebound (3.0 vs 3.4; P = .5). Treated participants had lower average daily VLs without VL rebound (0.9 vs 2.6; P < .01) but not statistically lower with VL rebound (4.8 vs 5.1; P = .7)., Conclusions: Individuals who completed N/R treatment experienced fewer symptoms and lower VL but rebound occured more often compared with untreated individuals. Providers should prescribe N/R, when indicated, and communicate rebound risk to patients., Competing Interests: Potential conflicts of interest. S. R. reports grant support from BioFire. H. Q.

- Abstract
Girls' education has for many decades been central to the global development agenda, due to its positive impact on girls' health and wellbeing. In this paper, the authors revisit boys' attitudes, behaviours and norms related to girls' education, following the Samata intervention to prevent girls' school dropouts in Northern-Karnataka, South India. Data were collected from 20 boys in intervention villages before and after the intervention, and analysis was undertaken using a thematic-framework approach. Findings suggest that while boys did hold some attitudes and beliefs that supported girls' education and delayed-marriage, these remained within the framework of gender-inequitable norms concerning girls' marriageability, respectability/family-honour. Participants criticised peers who sought to jeopardise girls' respectability by teasing and community gossip about girls-boys' communication in public. Boys who rejected prevailing norms of masculinity were subjected to gossip, ridicule and violence by the community. Boys' attitudes and beliefs supported girls' education but were conditional on the maintenance of gendered hierarchies at household and interpersonal levels. Social norms concerning girls' honour, respectability and the role of boys as protectors/aggressors appeared to influence boys' response to girls' school dropouts. Future interventions aiming to address girls' education and marriage must invest time and resources to ensure that intervention components targeting boys are relevant, appropriate and effective.

- Abstract
This study examined autonomic nervous system activity (respiratory sinus arrhythmia [RSA]) as a biomarker of psychopathology in an ethnically and socioeconomically diverse sample (N = 57) of young children ages 4-7 years. RSA was measured at baseline and across four standardized tasks designed to assess self-regulation in both affective (i.e., "hot") and cognitive (i.e., "cool") contexts during early childhood. Our findings reveal that age moderated RSA activity, such that reduced RSA suppression was associated with a heightened risk of externalizing problems among older children during "cool" and "hot" contexts; for younger children, only RSA suppression during "hot" contexts predicted externalizing risk. The influence of socioeconomic disadvantage did not moderate the relationship between RSA and the risk of psychopathology, and there were minimal associations between RSA suppression and internalizing symptoms at this age range. These results suggest that autonomic variability may be a more effective predictor of psychopathology risk in older children, perhaps as they transition into formal schooling and face increasingly complex cognitive and social demands. Findings have implications for the identification of psychopathology in early developmental periods when regulation over emotions becomes essential for academic and social success., (© 2024 Wiley Periodicals LLC.)

- Abstract
Age-disparate transactional sex is a major contributor to the disproportionate rates of HIV experienced by adolescent girls in sub-Saharan Africa, and a key driver of unintended adolescent pregnancy. This paper comprises one element of the impact evaluation of the Learning Initiative on Norms, Exploitation and Abuse (LINEA) radio drama intervention to prevent age-disparate transactional sex. It provides new insights into the radio drama's influence on distal drivers of age-disparate transactional sex identified in formative research: girls' own educational aspirations, and gendered attitudes towards work. The intervention, which targeted adolescent girls and their caregivers in the Shinyanga Region of Tanzania, uses an edutainment approach to prevent transactional sex between girls aged 12-16 years and men at least 5-10 years older. We distributed the 39-episode radio drama on USB flash drives to 331 households and conducted longitudinal in-depth interviews with 59 participants. We conducted a thematic analysis of endline (December 2021) transcripts from 23 girls, 18 women caregivers, and 18 men caregivers of girls (n = 59), and midline (November 2021) transcripts from a sub-sample of these participants: 16 girls, 16 women and 13 men (n = 45). Findings suggest the radio drama created an enabling environment for preventing age-disparate transactional sex by increasing girls' motivation to focus on their studies and remain in school. There was also strong evidence of increased gender-equitable attitudes about work among girls and women and men caregivers. These supported women joining the workforce in positions traditionally reserved for men and challenging the male provider role. Our findings suggest that the LINEA radio drama can supplement interventions that address structural drivers of age-disparate transactional sex. The radio drama may also have impacts beyond preventing age-disparate transactional sex, such as reducing girls' HIV morbidity and mortality, and challenging attitudes that promote sexual and gender-based violence to foster more gender-equitable communities across Tanzania., Competing Interests: The authors declare that no competing interests exist., (Copyright: © 2024 Pichon et al.

Objective: Patients who experience postoperative pediatric cerebellar mutism syndrome (CMS) during treatment for medulloblastoma have long-term deficits in neurocognitive functioning; however, the consequences on functional or adaptive outcomes are unknown. The purpose of the present study was to compare adaptive, behavioral, and emotional functioning between survivors with and those without a history of CMS., Methods: The authors examined outcomes in 45 survivors (15 with CMS and 30 without CMS). Comprehensive neuropsychological evaluations, which included parent-report measures of adaptive, behavioral, and emotional functioning, were completed at a median of 2.90 years following craniospinal irradiation., Results: Adaptive functioning was significantly worse in the CMS group for practical and general adaptive skills compared with the group without CMS. Rates of impairment in practical, conceptual, and general adaptive skills in the CMS group exceeded expected rates in the general population. Despite having lower overall intellectual functioning, working memory, and processing speed, IQ and related cognitive processes were uncorrelated with adaptive outcomes in the CMS group. No significant group differences or increased rates of impairment were observed for behavioral and emotional outcomes., Conclusions: Survivors with CMS, compared with those without CMS, are rated as having significant deficits in overall or general adaptive functioning, with specific weakness in practical skills several years posttreatment. Findings from this study demonstrate the high risk for ongoing functional deficits despite acute recovery from symptoms of CMS, highlighting the need for intervention to mitigate such risk.

- Abstract
Introduction: Sexual and gender minority people who live in rural areas are less likely to have had a HIV test in the previous 12 months compared with those who live in non-rural areas. We assessed the independent contribution of distance and time required to travel to receive a HIV test on recent uptake of HIV testing., Methods: We conducted a cross-sectional survey of sexual and gender minority populations in the southern US. We used Poisson regression with robust standard errors to estimate prevalence ratios to compare uptake of HIV testing in the previous 12 months among those who traveled more than 20 miles (~32 km) and more than 30 minutes to their most recent HIV test compared with those who traveled less distance and time to their most recent test, respectively., Results: A total of 508 (n=155 rural, n=348 non-rural) participants completed the survey. Of these, 398 (78.5%) had received a HIV test in the previous 12 months. Those who traveled more than 20 miles (~32 km) to their most recent test were more likely to have not received a HIV test in the previous 12 months compared with those who traveled 20 miles (~32 km) or less (adjusted prevalence ratio 2.25; 95% confidence interval 1.22-4.17). There were no differences based on travel time to the most recent test., Conclusion: Distance, but not time, to travel to receive a HIV test is independently associated with reduced HIV testing. More geographically proximal options or access to home-based testing might reduce this barrier.

- Abstract
A number of mobile HIV prevention interventions have been developed to increase uptake of HIV prevention services such as HIV testing and pre-exposure prophylaxis (PrEP). Most of these interventions have been tested among urban populations. However, sexual and gender minority (SGM) groups in rural areas might also benefit from mobile HIV prevention interventions. These groups have heightened experiences of stigma and discrimination and have limited access to culturally competent healthcare. We conducted a survey of SGM participants in the southern United States to assess willingness to use the common features of mobile HIV prevention interventions and to participate in research studies of these interventions and to compare the results between rural and non-rural respondents. We found few differences in willingness to use common features of mobile HIV prevention interventions based on rurality and high levels of cellular connectivity across participants. Based on these results, rural residence is not a barrier to using mobile HIV prevention interventions., (© 2023.

- Abstract
Neurocysticercosis (NCC) is a rare, potentially life-threatening parasitic infection endemic in many developing countries where pig farming and pork consumption are popular. The rates of neurocysticercosis could increase in the U.S. due to the influx of immigration from Central and South America, sub-Saharan Africa, and parts of Asia. Careful evaluation, diagnosis, and treatment is needed to prevent complications from the disease. We present a case of neurocysticercosis which presented as an unresponsive adult female in a rural South Dakota healthcare facility., (Copyright© South Dakota State Medical Association.)

- Abstract
This paper reflects on the development process (2015-2020) of the Learning Initiative for Norms, Exploitation, and Abuse (LINEA) Intervention. The LINEA Intervention is a multi-component social norms intervention to prevent age-disparate transactional sex in Tanzania. This paper aims to: (1) critically reflect on the LINEA Intervention development process by retrospectively comparing it with a pragmatic, phased framework for intervention development in public health, the Six Essential Steps for Quality Intervention Development (6SQuID); and (2) discuss the usefulness and applicability of this framework to guide intervention development for gender-based violence prevention. This paper contributes to a growing field of intervention development research to improve the designs of interventions to prevent gender-based violence. Findings showed that the LINEA Intervention development approach mostly aligned with the steps in 6SQuID framework. However, the LINEA Intervention development process placed particular emphasis on two phases of the 6SQuID framework. First, the LINEA Intervention development process included significant investment in formative research, feasibility testing, and refinement; and second, the LINEA Intervention was informed by a clearly articulated behavior change theory-social norms theory. Beyond the 6SQuID framework the LINEA Intervention development process: (i) followed a non-linear, iterative process; (ii) applied ongoing feasibility testing to refine the intervention, and (iii) relied on co-development with local implementers and participants. This paper suggests future components for a robust intervention development process, highlighting beneficial additions to the 6SQuID approach, a well-recognized intervention development sequence. Particularly useful additions include incorporating sufficient time, flexibility, and resources to foster meaningful collaborations and iteration on the intervention design., Competing Interests: Author LR was employed by Lori Rolleri Consulting Inc.

- Abstract
Background: Self-collection of specimens at home and their return by mail might help reduce some of the barriers to HIV and bacterial sexually transmitted infection (STI) screening encountered by gay, bisexual, and other men who have sex with men (GBMSM). To evaluate the benefits and challenges of bringing this approach to scale, researchers are increasingly requesting GBMSM to return self-collected specimens as part of web-based sexual health studies. Testing self-collected hair samples for preexposure prophylaxis drug levels may also be a viable option to identify GBMSM who face adherence difficulties and offer them support., Objective: Project Caboodle! sought to evaluate the acceptability and feasibility of self-collecting at home and returning by mail 5 specimens (a finger-stick blood sample, a pharyngeal swab, a rectal swab, a urine specimen, and a hair sample) among 100 sexually active GBMSM in the United States aged between 18 and 34 years. In this manuscript, we aimed to describe the key lessons learned from our study's implementation and to present recommendations offered by participants to maximize the rates of self-collected specimen return., Methods: Following the specimen self-collection phase, a subset of 25 participants (11 who returned all 5 specimens, 4 who returned between 1 and 4 specimens, and 10 who did not return any specimens) was selected for in-depth interviews conducted via a videoconferencing platform. During the session, a semistructured interview guide was used to discuss the factors influencing decisions regarding returning self-collected specimens for laboratory processing. The transcripts were analyzed using template analysis., Results: University branding of web-based and physical materials instilled a sense of trust in participants and increased their confidence in the test results. Shipping the specimen self-collection box in plain unmarked packaging promoted discretion during transit and on its receipt. Using different colored bags with matching color-coded instructions to self-collect each type of specimen minimized the potential for confusion. Participants recommended including prerecorded instructional videos to supplement the written instructions, providing information on the importance of triple-site bacterial STI testing, and adding a reminder of the types of testing that would and would not be conducted on hair samples. Participants also suggested tailoring the specimen self-collection box to include only the tests that they might be interested in completing at that time, adding real-time videoconferencing to the beginning of the study to introduce the research team, and sending personalized reminders following the delivery of the specimen self-collection box., Conclusions: Our results offer valuable insights into aspects that facilitated participant engagement in self-collected specimen return, as well as areas for potential improvement to maximize return rates. Our findings can help guide the design of future large-scale studies and public health programs for home-based HIV, bacterial STI, and preexposure prophylaxis adherence testing., International Registered Report Identifier (irrid): RR2-10.2196/13647., (©Gregory Sallabank, Rob Stephenson, Monica Gandhi, Leland Merrill, Akshay Sharma.

- Abstract
Objective: to investigate the impact of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic on older Hispanic adults., Methods: A total of 522 participants (or their family member, if deceased) from the Boston Puerto Rican Health Study were asked whether they had been diagnosed with SARS-CoV-2, across 2 survey phases. In phase 1 (May - Aug 2020, n=497), participants answered survey questions related to SARS-CoV-2 exposure, diagnosis, and transmission and 5 family members reported deaths. In phase 2, participants were again surveyed (January - June 2021; n=420, and 2 family members reported deaths). SARS-CoV-2 diagnosis and/or death apparently from SARS-CoV-2 was self-reported., Results: In 2020, 5.2% reported that they had been SARS-CoV-2 positive; by June 2021, a cumulative 11.0% reported having been SARS-CoV-2 positive (including cases and deaths in the first survey). A total of 7 participants (1.3%) reportedly died from SARS-CoV-2. Language acculturation was significantly lower among participants with SARS-CoV-2 (13.7 ± 17.9) vs. without SARS-CoV-2 (20.0 ± 21.4; P = 0.049). Mean length of return to usual health was 28 ± 38 days (range: 0-210 days; median = 15 days). Depressive symptomatology was significantly lower during the pandemic (CES-D score: 13.4 ± 11.6) compared to the same participants pre-pandemic (17.8 ± 11.7; P = 0.001). Compared to the months before the pandemic, 32% (n=135) of participants reported greater communication with friends and family, and 41% (n=172) reported no change., Conclusions: Public health models should be personalized to communities, considering their unique structures and cultural beliefs. Social resiliency may be key for future programmatic responses to pandemics to reduce the mental health burden., Competing Interests: The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper.

- Abstract
Few studies among gay, bisexual and other men who have sex with men (GBMSM) have examined facilitators and barriers to self-collecting specimens for extragenital STI screening, and none have evaluated attitudes towards self-collecting hair samples that can be utilized for PrEP drug level testing to assess adherence. To address this gap, we interviewed 25 sexually active GBMSM who were offered a choice to self-collect and return finger-stick blood samples (for actual HIV testing), pharyngeal swabs, rectal swabs and urine specimens (for actual gonorrhea and chlamydia testing), and hair samples (to visually determine their adequacy for PrEP drug level testing): 11 who returned all, 4 who returned some, and 10 who did not return any. Participants found self-collecting finger-stick blood samples and rectal swabs more challenging than other specimens. Frequently discussed facilitators of return included an opportunity to confirm one's HIV or STI status, limited access to a healthcare provider and a desire to advance research focusing on home-based testing. Commonly cited barriers to return included low self-efficacy pertaining to self-collection and apprehension around the possibility of delay or loss of specimens during transit. Offering additional support such as real-time video conferencing may prove helpful in future field-based research with GBMSM., (© 2022.

- Abstract
Introduction: Long-acting injectable (LAI) pre-exposure prophylaxis (PrEP) for HIV prevention was approved by the U.S. Food and Drug Administration in 2021. LAI PrEP is more effective than oral PrEP. However, it is not clear whether the groups most at risk of HIV in the United States will use LAI PrEP. Willingness to use LAI PrEP and preference for LAI versus oral PrEP has not been reported for sexual and gender minority (SGM) people in the southern United States, where the HIV epidemic is concentrated. Our goal was to assess willingness to use LAI PrEP and preference for oral versus LAI PrEP among SGM people in the southern United States and to assess differences in willingness by demographics and sexual behaviour., Methods: We conducted an online, cross-sectional survey of SGM people aged 15-34 years in the southern United States (n = 583). Participants reported willingness to use LAI PrEP and preferences for LAI PrEP versus daily oral PrEP. We assessed bivariate associations and adjusted prevalence ratios for the LAI-PrEP-related outcomes and key demographic and behavioural characteristics., Results: Overall, 68% of all participants (n = 393) reported being willing to use LAI PrEP that provides protection against HIV for 3 months. Of those, most (n = 320, 81%) indicated a preference for using LAI PrEP, compared to a daily oral pill or no preference. Willingness to use LAI PrEP was more common among transgender and non-binary participants and participants who engaged in condomless anal intercourse in the last 6 months. Hispanic participants were more likely and non-Hispanic Black participants were less likely to report willingness to use LAI PrEP compared to non-Hispanic White participants., Conclusions: Willingness to use LAI PrEP was high among SGM people in the southern United States, although there were some important differences in willingness based on demographic characteristics. Decreased willingness to use LAI PrEP among groups who are disproportionately affected by the HIV epidemic, such as non-Hispanic Black SGM people, could exacerbate existing disparities in HIV incidence. LAI PrEP is an acceptable option among SGM populations in the southern United States, but strategies will be needed to ensure equitable implementation., (© 2023 The Authors.

- Abstract
Background: Although treatment and control of diabetes can prevent complications and reduce morbidity, few data sources exist at the state level for surveillance of diabetes comorbidities and control. Surveys and electronic health records (EHRs) offer different strengths and weaknesses for surveillance of diabetes and major metabolic comorbidities. Data from self-report surveys suffer from cognitive and recall biases, and generally cannot be used for surveillance of undiagnosed cases. EHR data are becoming more readily available, but pose particular challenges for population estimation since patients are not randomly selected, not everyone has the relevant biomarker measurements, and those included tend to cluster geographically., Methods: We analyzed data from the National Health and Nutritional Examination Survey, the Health and Retirement Study, and EHR data from the DARTNet Institute to create state-level adjusted estimates of the prevalence and control of diabetes, and the prevalence and control of hypertension and high cholesterol in the diabetes population, age 50 and over for five states: Alabama, California, Florida, Louisiana, and Massachusetts., Results: The estimates from the two surveys generally aligned well. The EHR data were consistent with the surveys for many measures, but yielded consistently lower estimates of undiagnosed diabetes prevalence, and identified somewhat fewer comorbidities in most states., Conclusions: Despite these limitations, EHRs may be a promising source for diabetes surveillance and assessment of control as the datasets are large and created during the routine delivery of health care., Trial Registration: Not applicable., (© 2022.

- Abstract
Introduction: Age-disparate transactional sex (ADTS) is associated with HIV, unintended pregnancy, school dropout and violence, yet few interventions have successfully prevented it, and none have set ADTS prevention as their primary outcome. This exploratory evaluation aimed to assess indications of change after exposure to the Learning Initiative on Norms, Exploitation and Abuse (LINEA) intervention, a mass-media, gender-transformative social norms intervention aimed at preventing ADTS in Tanzania., Methods: In a condensed implementation 331 participants were instructed to listen to the LINEA radio drama over seven weeks, and 60 were randomly allocated to household discussion sessions about content. In-depth interviews ( n = 81) from girls aged 12-16 years, and women and men caregivers were collected at baseline (September 2021), midline (November) and endline (December 2021). Surveys were conducted ( n = 120) at baseline and endline using the Norms and Attitudes on ADTS Scale (NAATSS) and the Gender Roles and Male Provision Expectations (GRMPE) scale. Interviews were thematically analyzed using a framework approach. Age-stratified linear regression models adjusted for baseline scores were used to measure association between the intervention and endline scale scores., Results: Longitudinal data were available from 59 qualitative (73%) and 95 quantitative participants (79%). Qualitative evidence revealed the drama facilitated family conversations about adolescent challenges, allowing caregivers to advise daughters. Some girls gained confidence to refuse men's gifts, learning that accepting them could necessitate sexual reciprocation. Some caregivers felt increased responsibility for supporting girls in the community to avoid ADTS. Blame for ADTS shifted for some from girls to men, suggesting increased understanding of inequitable power dynamics and reductions in victim blaming. Marginal quantitative evidence revealed that highly exposed girls had improved gender equitable beliefs on the GRMPE ( β = -6.26; 95% CI: -12.94, 0.42). Moderately exposed men had increased gender inequitable norms on the NAATSS subscale ( β = 0.42 95% CI: 0.05, 0.79), but there was no effect in highly exposed men., Conclusions: Given the small sample results should be interpreted cautiously. Our initial findings indicate high engagement with the LINEA intervention shows promise in shifting knowledge, behaviors, and attitudes, beliefs and social norms driving ADTS in Shinyanga, Tanzania, supporting a robust impact evaluation., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (© 2022 Pichon, Carter, Howard-Merrill, Sono, Gimunta, Rutenge, Thiaw, Stoebenau, Perrin and Buller.)

- Abstract
This paper explores adolescent girls' and young women's (AGYW) aspirations, factors that influence aspirations, and how their aspirations inform their sexual decision-making and behaviour. This study employed a qualitative design involving six participatory focus group discussions and 17 in-depth interviews with AGYW in - and out-of-school. Fieldwork was undertaken in rural and urban Tanzania. Thematic analysis was conducted using NVIVO software. Aspirations of AGYW's were categorised as short and long-term. Short-term aspirations were associated with the social status derived from obtaining trendy items such as nice clothing, or smart phones. Long-term aspirations included completing secondary education, having a professional job, being respected, getting married and having children. Aspirations were influenced by aspects of the social context, such as peers and structural factors that dictated what was acceptable for respectable AGYW. AGYW lacked the independent capabilities to meet long-term aspirations such as completing education. In pursuit of their short - and long-term aspirations, AGYW engaged in higher risk sexual behaviours such as transactional sex, age-disparate sex and condomless sex. AGYW's aspirations were important in determining their sexual decision making. Interventions should capitalise on AGYW's aspirations when addressing their SRH risks by finding innovative ways of engaging them based on their circumstances and aspirations.

- Abstract
Introduction: Ugandan adolescent girls and young women are disproportionately impacted by human immunodeficiency virus, and this is largely driven by their engagement in transactional sex. Globally, parent-daughter communication about sex is associated with increased contraceptive use and delayed/decreased sexual activity, but research on parent-daughter communication about transactional sex is lacking. This paper elucidates local perspectives on, and experiences of parent-daughter communication about sex and transactional sex, to inform family-level comprehensive sexuality education interventions., Methods: We conducted a secondary, thematic analysis of 13 focus group discussions (n = 119) and 30 in-depth interviews collected between 2014 and 2015 with adolescent girls and young women aged 14+, and men and women in Kampala and Masaka., Results: We found that parents used three approaches to discuss sex and transactional sex with their daughters: (1) frightening their daughters into avoiding sex; (2) being "strict"; and (3) relying on mothers rather than fathers to "counsel" daughters. Mother-daughter communication about transactional sex was common, but frequently unidirectional. Adolescent girls and young women bringing home gifts sparked conversations about the risks of transactional sex, although less in poorer households. Mothers felt they lacked control over their daughters' sexual behaviors and thus restricted their movements and friendships to try to prevent them from having sex. In contrast to previous research, we found some evidence of mothers encouraging condom use and father-daughter communication about sex., Conclusions: Family-level comprehensive sexuality education interventions targeting parent-daughter communication about sex could further highlight the role that fathers might play, and emphasize communication about the inequitable power dynamics in transactional sex and condom negotiation skills, while reducing fear surrounding parent-daughter communication., (© 2022 The Authors.

- Abstract
Web-based HIV and sexually transmitted infection (STI) prevention studies are increasingly requesting gay, bisexual, and other men who have sex with men (GBMSM) to return self-collected specimens for laboratory processing. Some studies have solicited self-collected extragenital swabs for gonorrhea and chlamydia testing, but to date, none have solicited self-collected hair samples for pre-exposure prophylaxis (PrEP) adherence testing. Project Caboodle! offered 100 racially/ethnically diverse GBMSM aged 18 to 34 years residing across the United States a choice to self-collect at home and return by mail any of the following: a finger-stick blood sample (for HIV testing), a pharyngeal swab, a rectal swab and a urine specimen (for gonorrhea and chlamydia testing), and a hair sample (to visually assess its adequacy for PrEP drug level testing). Despite not incentivizing specimen return, 51% mailed back at least one type of specimen within 6 weeks (1% returned three specimens, 11% returned four specimens and 39% returned all five specimens). The majority of returned specimens were adequate for laboratory processing. Significantly more participants without a college education ( p = .0003) and those who were working full-time or part-time ( p = .0070) did not return any specimens. In addition, lower levels of HIV-related knowledge ( p = .0390), STI-related knowledge ( p = .0162), concern about contracting HIV ( p = .0484), and concern about contracting STIs ( p = .0108) were observed among participants who did not return any specimens. Self-collection of specimens holds promise as a remote monitoring strategy that could supplement testing in clinical settings, but a better understanding of why some GBMSM may choose to fully, partially, or not engage in this approach is warranted.

- Abstract
Background: Mobile health (mHealth) interventions, including smartphone apps, have been found to be an effective means of increasing the uptake of HIV prevention tools, including HIV and sexually transmitted infection (STI) tests and pre-exposure prophylaxis. However, most HIV prevention mHealth apps tested in the United States have been tested among populations living in areas surrounding urban centers. Owing to reduced access to broadband internet and reliable cellular data services, it remains unclear how accessible and effective these interventions will be in rural areas. In addition, gay and bisexual men who have sex with men and gender minority populations in rural areas experience enhanced stigma when compared with their more urban counterparts, and these experiences might affect their willingness and interest in mHealth apps., Objective: This study aimed to conduct online focus groups with men who have sex with men and transgender and gender diverse populations in the rural southern United States to assess their interest in mHealth HIV prevention apps and the features that they would be the most interested in using., Methods: Focus group participants were recruited from a larger pool of sexual and gender minority respondents to a web-based research survey. The participants indicated that they would be willing to participate in an online focus group discussion. Focus groups were conducted via secure Zoom (Zoom Video Communications Inc) videoconferencing. During the focus group discussions, participants were asked to discuss their experiences with HIV and STI prevention and how these experiences were affected by living in a rural area. They were then shown screenshots of a new app to promote HIV and STI prevention among rural populations and asked to provide their opinions on the app's features. The transcripts of the discussions were reviewed and coded using a constant comparative approach., Results: A total of 6 focus groups were conducted with 26 participants. Most participants were cisgender gay and bisexual men who have sex with men (19/26, 73%); the remaining participants were transgender men (2/26, 8%), were nonbinary people (2/26, 8%), or had multiple gender identities (3/26, 12%). Participants reported numerous barriers to accessing HIV and STI prevention services and accurate information about HIV and STI prevention options. Overall, the participants reported a high degree of interest in mHealth interventions for HIV and STI prevention and suggested several recommendations for the features of an app-based intervention that would be the most useful for rural residents., Conclusions: These focus group discussions indicate that rural residence is not a major barrier to mHealth HIV and STI prevention intervention implementation and that there is a high degree of interest in these approaches to HIV and STI prevention., (©Jeb Jones, O Winslow Edwards, Leland Merrill, Patrick S Sullivan, Rob Stephenson.

- Abstract
Men's role in transactional sex is relatively unexplored, limiting initiatives to prevent exploitative transactional sex and its negative health implications for girls and women. We addressed this literature gap by conducting eight focus group discussions and twenty in-depth-interviews with boys and men aged 14 - 49 years in 2015 in Tanzania. We employed a novel combination of theoretical perspectives - gender and masculinities, and social norms - to understand how transactional sex participation contributes to perpetuating gendered hierarchies, and how reference groups influence men's behaviour. Findings signal two gender norms that men display within transactional sex: the expectation of men's provision in sexual relationships, and the expectation that men should exhibit heightened sexuality and sexual prowess. Adherence to these expectations in transactional sex relationships varied between older and younger men and created hierarchies among men and between men and women and girls. We found that approval of transactional sex was contested. Although young men were likely to object to transactional sex, they occupied a structurally weaker position than older men. Findings suggest that interventions should employ gender synchronised and gender transformative approaches and should prioritise the promotion of alternative positive norms over preventing the exchange of gifts or money in relationships.

- Abstract
Drug courts have been in operation for decades to provide treatment alternatives to individuals whose substance use and related behaviors have brought them into contact with the criminal justice system. As research on drug courts have evolved, it has been demonstrated that different types of offenders have different mental health and substance use treatment needs. One way of approaching treatment in court-mandated substance use treatment is by the application of the risk-need-responsivity (RNR) model (Andrews, Zinger et al., 1990). The Orleans Parish Drug Court expanded assessment and treatment services to determine whether the implementation of alternative substance use programming within a traditional drug court model improved outcomes. The goals of the current study were to describe the process of implementing risk and need principles, provide a description of client characteristics, examine the factors related to successful completion of drug court, and investigate completion rates across risk and need groups. Results demonstrated that risk and need groups differed on several demographic variables, levels of substance use, mental health concerns, and legal issues, suggesting assessment and triage procedures were successful. Comparisons between individuals who successfully completed drug court and those who were terminated prematurely also showed significant differences. Specifically, baseline age, education, substance use problems and frequency, and days in jail/prison were unique predictors of successful drug court completion. Finally, as predicted, individuals in the group with the lowest risk and need had the highest graduation rate, despite receiving less intensive services. Overall, creation of specialized treatment tracks within a traditional drug court program appears to be an effective strategy to target the wide range of offenders typical of drug court participants., (Copyright © 2021 Elsevier Inc.
