Social stigma within Korean society hinders structural efforts to reduce HIV disparities among sexual minority men (SMM). To date, however, there have been limited intervention efforts to reduce HIV disparities among SMM in Korea. Therefore, the current mixed-methods study (n = 180) explored young Korean SMM's perspectives on the acceptability of HIV prevention mHealth interventions to inform effective strategies for future intervention studies. We then analyzed participants' comments and suggestions on HIV research and examined associations with the acceptability of mHealth interventions. Through our textual coding and analysis, we identified four primary themes for comments and suggestions for HIV research in Korea: the centrality of stigma, health service accessibility, informational accessibility, and cultural adaptation. Our study suggests culturally adapted HIV intervention addressing stigma, health service accessibility, and information accessibility and mHealth interventions disseminating information and resources for stigmatized young SMM in Korea.

Black men who have sex with men (BMSM) face disproportionately higher risks for adverse sexual health outcomes compared to their non-Hispanic White counterparts. This disparity can be attributable to overlapping and intersecting risk factors at the individual and structural levels and can be understood through syndemic theory. Using longitudinal data from the HealthMPowerment trial (n = 363), six conditions related to stigma syndemics were indexed as a cumulative risk score: high alcohol use, polydrug use, depression and anxiety symptomology, and experiences of racism and sexual minority stigma. Using Poisson regression, we found a positive association between baseline risk scores and sexual risk behavior (b: 0.32, SE: 0.03, p 0.001). Using a Generalized Estimating Equation, we also found a 0.23 decrease in the within-participant risk scores at 3-month follow-up (SE: 0.10, p 0.020). Future work examining how care and prevention trials improve health outcomes in this population is needed.

Behavioral HIV interventions focused on strengthening young sexual minority men's (SMM) internal (assets) and external (resources) protective factors are promising, yet their evaluation as resilience-supportive strategies to minimize or negate HIV-related risks remain understudied. The objective of this scoping review was to describe resilience-supportive intervention strategies that have been used to achieve desired HIV behavioral outcomes and to identify how these strategies have been evaluated using a resilience analytic framework. Our scoping review uncovered 271 peer-reviewed articles, of which 38 were eligible for inclusion based on our review criteria. The majority of interventions relied on social support strategies as their primary resilience-supportive strategy. A third of interventions reviewed analyzed their findings from a deficits-focused model, another third used compensatory resilience models, and the remaining interventions employed a hybrid (i.e., deficit and compensatory model) strategy. None of the interventions evaluated their intervention effects using a risk-protective model. From our synthesis regarding the current state of research around resilience-informed interventions, we propose strategies to inform the design of resilience-supportive approaches and make recommendations to move the field forward on how to develop, implement, and measure young SMM's resiliency processes.

Purpose: Poor body composition metrics (BCM) are associated with inferior cancer outcomes; however, in early breast cancer (EBC), there is a paucity of evidence regarding the impact of BCM on toxicities. This study investigates associations between BCM and treatment-related toxicity in patients with EBC receiving anthracyclines and taxane–based chemotherapy.Experimental Design: Pretreatment computerized tomographic (CT) images were evaluated for skeletal muscle area (SMA), skeletal muscle density (SMD), and fat tissue at the third lumbar vertebrae. Skeletal muscle index (SMI = SMA/height2) and skeletal muscle gauge (SMG = SMI × SMD) were also calculated. Relative risks (RR) are reported for associations between body composition measures and toxicity outcomes, after adjustment for age and body surface area (BSA).Results: BCM were calculated for 151 patients with EBC (median age, 49 years; range, 23–75 years). Fifty patients (33%) developed grade 3/4 toxicity, which was significantly higher in those with low SMI (RR, 1.29; P = 0.002), low SMG (RR, 1.09; P = 0.01), and low lean body mass (RR, 1.48; P = 0.002). Receiver operating characteristic analysis showed the SMG measure to be the best predictor of grade 3/4 toxicity. Dividing SMG into tertiles showed toxicity rates of 46% and 22% for lowest versus highest tertile, respectively (P = 0.005). After adjusting for age and BSA, low SMG (P = 0.02), gastrointestinal grade 3/4 toxicities (RR, 6.49; P = 0.02), and hospitalizations (RR, 1.91; P = 0.05).Conclusions: Poor BCMs are significantly associated with increased treatment-related toxicities. Further studies are needed to investigate how these metrics can be used to more precisely dose chemotherapy to reduce treatment-related toxicity while maintaining efficacy.

Despite the increased use of geosocial networking applications for finding sexual partners among young men who have sex with men (YMSM), few studies have examined the intricate patterns of online dating behaviors. In order to advance understanding of online dating patterns among YMSM, various factors, including how frequently and how much time is spent within partner-seeking sites, need to be examined concurrently. Therefore, we used latent profile analysis to identify online dating patterns and logistic regressions to examine their associations with sexual behaviors and relationship characteristics among single YMSM (N = 180; ages 18-24). We found three online dating patterns: discouraged users (N = 93, 52%), date seekers (N = 67, 37%), and instant lovers (N = 20, 11%). Discouraged users were less likely to seek sexual sensational activities, while date seekers were more likely to seek sexual sensational activities. Moreover, instant lovers were less likely to pursue committed romantic relationships, while they reported a higher number of condomless anal intercourse. Given that online dating patterns are not homogeneous, HIV prevention interventions may benefit from tailored approaches based on YMSM's different online dating profiles.

Purpose Although epidermal growth factor receptor (EGFR)-activating mutations in non-small cell lung cancer (NSCLC) usually show sensitivity to first-generation EGFR-tyrosine kinase inhibitors (TKIs), most patients relapse because of drug resistance. Heat shock protein 27 (HSP27) has been reported to be involved in the resistance of EGFR-TKIs, although the underlying mechanism is unclear. Here, we explore the mechanisms of HSP27-mediated EGFR TKI resistance and propose novel therapeutic strategies. Methods To determine the mechanism of HSP27 associated gefitinib resistance, differences were assessed using gefitinib-sensitive and -resistant NSCLC cell lines. In vivo xenograft experiments were conducted to elucidate the combinatorial effects of J2, a small molecule HSP27 inhibitor, and gefitinib. Analyses of human NSCLC tissues and PDX tissues were also used for comparison of HSP27 and phosphorylated AKT expression. Results Large-scale cohort analysis of NSCLC cases revealed that HSP27 expression correlated well with the incidence of EGFR mutations and affected patient survival. Increased pAKT and HSP27 was observed in gefitinib-resistant cells compared with gefitinib-sensitive cells. Moreover, increased phosphorylation of HSP27 by gefitinib augmented its protein stability and potentiated its binding activity with pAKT, which resulted in increased gefitinib resistance. However, in gefitinib-sensitive cells, stronger binding activity between EGFR and HSP27 was observed. Moreover, these phenomena occurred regardless of EGFR mutation including secondary mutations, such as T790M. AKT knockdown switched HSP27-pAKT binding to HSP27-EGFR, which promoted gefitinib sensitivity in gefitinib-resistant cells. Functional inhibition of HSP27 yielded sensitization to gefitinib in gefitinib-resistant cells by inhibiting the interaction between HSP27 and pAKT. Conclusions Our results indicate that combination of EGFR-TKIs with HSP27 inhibitors may represent a good strategy to overcome resistance to EGFR-TKIs, especially in cancers exhibiting AKT pathway activation.

Linkage to and retention in HIV care, as conceptualized in the HIV care continuum, remain critical steps towards achieving and maintaining viral suppression. We evaluated recently published (Jan 2018–Nov 2020) peer-reviewed clinical trials of linkage to and retention in care outcomes in the United States. We identified 12 trials evaluating linkage to and retention in care outcomes in the United States. Most trials did not adhere to standardized definitions or metrics for linkage to or retention in HIV care, hindering comparisons between studies. Four interventions indicated improvements on linkage to or retention in HIV care at follow-up, relying on behavioral incentives and/or case management as key intervention strategies. We recommend the adoption standardize metrics across linkage and retention trials, and the future use of implementation science frameworks to identify implementation facilitators and barriers, and evaluate key strategies associated with improvements in linkage to and retention in care.

Proteases can serve as molecular switches to initiate a wide spectrum of biological events. High efficiency and specificity enhance the potential of proteases as versatile elements in synthetic biological circuits. To address the unmet need for a novel protease-based toolkit with modular features, we developed a single-component photocleavable switch, termed LAUNCHER (Light-Assisted UNcaging switCH for Endoproteolytic Release), combining a circularly permuted potyviral protease and a blue-light-gated substrate with variable intermodular linkers. LAUNCHER enables user-controllable release of payloads that can serve in various cellular applications, such as transgene expression, multilayer-based G protein-coupled receptor (GPCR) activity sensing, and optochemogenetic manipulation. Moreover, LAUNCHER orthologs from the orthogonal potyviral protease family can be utilized in a multiple protease-based circuit without mutual interference. LAUNCHER provides a generalized method to implant optogenetic manipulations into existing synthetic biological circuits in a plug-and-play manner and adds to optogenetic toolboxes for the expansion of biomedical fields.

BACKGROUND Efficacious mental health interventions for sexual and gender minority youth (SGMY) have had limited reach given their delivery as time intensive, in-person sessions. Internet-based interventions may facilitate reach to SGMY, yet there is little research examining their efficacy. OBJECTIVE We describe the results of a pilot randomized controlled trial of imi, a web app designed to improve mental health by supporting LGBTQ+ identity affirmation, coping self-efficacy, and coping skill practice. METHODS SGMY(N=270) living in the US, ages 13 to 19 (Mean 16.5, SD 1.5 years) were recruited through Instagram ads. Nearly 78% of the sample identified as a racial and/or ethnic minority. Participants were randomized in a 1:1 fashion to the full imi intervention web app (treatment, n=135) or a resource page-only version of the imi site (control, n=135). imi covered four topical areas: gender identity, LGBTQ+ identity, stress and coping, and internalized homophobia and transphobia. Participants explored these areas by engaging with informational resources, interactive exercises, and peer stories at a self-guided pace. Both arms were assessed via web-based surveys at baseline and 4-week follow-up for intervention satisfaction, stress appraisals (i.e., challenge, threat, resource), coping skills (i.e., instrumental support, positive reframing, planning), and mental health symptoms, among other outcomes. Main ‘intent-to-treat’ analyses compared the arms at week 4, controlling for baseline values on each outcome. RESULTS Results: Survey retention was 90% at week 4. Participants in the treatment arm reported greater satisfaction with the intervention than participants in the control arm (t241=-2.98; p=.003). The treatment arm showed significantly greater improvement in challenge appraisals (i.e., belief in one’s coping abilities) than the control (Cohen d=0.26; p=.008). There were no differences between the arms for threat (d=0.10; p=.37) or resource (d=0.15; p=.14) appraisals. The treatment arm showed greater increases in coping skills than the control arm (instrumental support: d=0.24, p=.005; positive reframing: d=0.27, p=.02; planning: d=0.26, p=.02). Mental health symptoms improved across both the treatment and control arms; however, there were no differences between arms. Within the treatment arm, higher engagement with imi (>=5 sessions, >10 minutes, or >10 pages) predicted greater improvement in stress appraisals (all ps CONCLUSIONS Results provide initial evidence that asynchronous psychosocial interventions delivered via a web app to SGMY can support their ability to cope with minority stress. Further research is needed to examine the long-term effects of imi. CLINICALTRIAL Clinical Trials.gov NCT05061966; https://clinicaltrials.gov/ct2/show/NCT05061966

Sexual empowerment represents an important HIV intervention strategy, yet limited attention has examined the multidimensional nature of sexual empowerment in prior studies. Using a sample (n = 465) of young Black men who have sex with men (MSM), we used confirmatory factor analysis (CFA) to test a multifactorial operationalization of sexual empowerment. CFA indicated that a bifactor model was best suited to characterize the sexual empowerment factor (SEF), suggesting that items for four sub-constructs (self-efficacy to refuse sexual behavior, emotional support, condom use self-efficacy, and social norms on condom use) contributed to their respective constructs, while also contributing to a latent sexual empowerment construct. We then examined the association between SEF and mental health outcomes (anxiety and depression symptoms) and safer sex intentions. SEF was negatively associated with mental health outcomes and positively associated with safer sex intentions. Ultimately, individuals with greater sexual empowerment might be better equipped to develop strategies to buffer their vulnerability to HIV. We discuss the implications of SEF as a bifactor during the design and evaluation of HIV risk-reduction interventions seeking to address sexual empowerment among MSM.

Lifestyle interventions may reduce inflammation and lower breast cancer (BrCa) risk. This randomized trial assessed the impact of the Sistas Inspiring Sistas Through Activity and Support (SISTAS) study on plasma C-reactive protein (CRP), interleukin-6 (IL-6) and Dietary Inflammatory Index (DII). This unblinded, dietary and physical activity trial was implemented in 337 obese (body mass index [BMI] ≥30 kg/m(2)) African American (AA) women recruited between 2011 and 2015 in South Carolina through a community-based participatory approach with measurements at baseline, 3 months, and 12 months. Participants were randomized into either intervention (n=176) or wait-list control group (n=161). Linear mixed-effect models were used for analyses of CRP and IL-6. Baseline CRP was significantly higher in those with greater obesity, body fat percentage, and waist circumference (all p-values

Background Hospitalized older adults have significant geriatric deficits that may lead to poor outcomes. We conducted a randomized trial to investigate the effectiveness of providing clinicians with a real-time geriatric assessment (GA) report in nonelectively hospitalized older patients with cancer. Subjects, Materials, and Methods We developed a web-based software platform for administering a modified GA (Cancer 2005;104:1998–2005) to older (>70 years) nonelectively hospitalized patients with pathologically confirmed malignancy. Patients were randomized to have their GA report provided to their treating clinicians (Intervention arm) or not provided (Control arm). Results Our study included 135 patients, median age 76 years, 52% female, 75% white, 21% black, 79% greater than high school education, 59% married, and 17% living alone. All patients had at least one GA-identified deficit, including physical function deficits (90%), cognitive impairment (22%), >5 comorbidities (28%), polypharmacy (>9 medications; 38%), weight loss ≥10% in the past 6 months (40%), anxiety (32%), or depression (30%). There was no difference between the Intervention (6%) and Control arms (9%) in the proportion of patients who were referred by their clinical team for an intervention to address a deficit (p = .53). Conclusion Many older nonelectively hospitalized patients with cancer have geriatric deficits that are amenable to evidence-based interventions. Real-time GA reports provided to the care team prior to discharge did not influence provider referral for such interventions. There is a need for systems-level interventions to address deficits in this vulnerable patient population. Implications for Practice Geriatric deficits are common in hospitalized older adults with cancer and lead to poor outcomes. Addressing modifiable deficits represents an appealing way to improve outcomes. Widespread geriatrician consultation is impractical owing to resource and personnel constraints. This work tested whether prompt delivery of a mostly self-administered, web-based geriatric assessment report to clinicians improved referral rates for evidence-informed interventions. It confirmed frequent geriatric deficits and high readmission rates in this population but found that real-time geriatric assessment reporting did not influence provider referral for evidence-informed interventions on geriatric assessment identified deficits. These findings highlight the need for systems-level intervention to improve outcomes in this vulnerable patient population.

BackgroundAt the start of the COVID-19 pandemic, HIV experts suggested that an increase in mental health diagnoses and substance use among people living with HIV (PLHIV) may be an unintended consequence of COVID-19 mitigation efforts (e.g., limiting social contact). We evaluated short-term trajectories in binge drinking, marijuana, and recreational drug use in a prospective cohort of PLHIV.MethodsData (N=2121 PLHIV) consist of survey responses on substance use behaviors from two pre-COVID-19 (October 2018-September 2019) and one COVID-19-era (April 2020-September 2020) timepoints within the MACS/WIHS Combined Cohort Study (MWCCS). We conducted group-based trajectory models, triangulated with generalized linear mixed models, to assess changes in binge drinking, daily marijuana use, and recreational drug use at the start of the pandemic. Controlling for age and race/ethnicity, we tested whether trajectories differed by sex and early-pandemic depressive symptoms, loneliness, and social support.ResultsGroup-based trajectory models yielded two trajectory groups for binge drinking (none vs. any), marijuana (none/infrequent vs. daily), and recreational drug use (none vs. any). Binge drinking and recreational drug use decreased at the beginning of the pandemic. Generalized linear mixed model supported these trends. Consistent with prior research, male sex and having depressive symptoms early pandemic were positively associated with each substance use outcomes. Social support was inversely associated with recreational drug use.ConclusionsContrary to hypotheses, problematic substance use behaviors decreased from pre-pandemic to the post-pandemic follow-up in our sample of PLHIV. Ongoing surveillance is needed to assess whether this pattern persists as the pandemic continues.

Expression of heat shock protein (HSP) correlates with the oncogenic status of malignant cells and plays an important role in tumorigenesis. HSP27 is constitutively expressed at specific stages of cancer development, and several clinical trials have reported correlations between HSP27 expression and tumor progression, metastasis, and chemoresistance in various types of cancer cells. These findings indicate that HSP27 is a major drug target, particularly in chemo-resistant cancers. As part of our ongoing efforts to improve the previously identified J2, a HSP27 cross-linker, we, in this study, report the identification of NK16 as a novel inducer of abnormal HSP27 dimers that did not affect the expression of HSP90 in an NCI-H460 lung cancer cell model. When NCI-H460 cells were treated with NK16 in combination with the anticancer drug cisplatin or paclitaxel, cleavage of PARP and caspase-3 was increased compared to administration of cisplatin or paclitaxel alone. Similar results were obtained in an NCI-H460-xenografted mouse model, in which tumor growth was suppressed more by co-administration of NK16 and paclitaxel than by paclitaxel alone. We propose NK16 as a meaningful strategy to improve the anticancer efficacy of cisplatin and paclitaxel.

BACKGROUND Digital HIV interventions (DHI) have been efficacious in reducing sexual risk behaviors among sexual minority populations, yet challenges in promoting and sustaining users’ engagement in DHI persist. Understanding the correlates of DHI engagement and their impact on HIV-related outcomes remains a priority. This study used data from a DHI (myDEx) designed to promote HIV prevention behaviors among single young men who have sex with men (YMSM; ages 18-24 years) seeking partners online. OBJECTIVE The goal of this study is to conduct a secondary analysis of the myDex project data to examine whether YMSM’s online behaviors (eg, online partner-seeking behaviors and motivations) are linked to participants’ engagement (ie, the number of log-ins and the number of sessions viewed). METHODS We recruited 180 YMSM who were randomized into either myDEx arm or attention-control arm using a stratified 2:1 block randomization. In the myDEx arm, we had 120 YMSM who had access to the 6-session intervention content over a 3-month period. We used Poisson regressions to assess the association between YMSM’s baseline characteristics on their DHI engagement. We then examined the association between the participants’ engagement and their self-reported changes in HIV-related outcomes at the 3-month follow-up. RESULTS The mean number of log-ins was 5.44 (range 2-14), and the number of sessions viewed was 6.93 (range 0-22) across the 3-month trial period. In multivariable models, the number of log-ins was positively associated with high education attainment (estimated Poisson regression coefficient [β]=.22; P=.045). The number of sessions viewed was associated with several baseline characteristics, including the greater number of sessions viewed among non-Hispanic YMSM (β=.27; P=.002), higher education attainment (β=.22; P=.003), higher perceived usefulness of online dating for hookups (β=.13; P=.002) and perceived loneliness (β=.06; P=.004), as well as lower experienced online discrimination (β=–.01; P=.007) and limerence (β=–.02; P=.004). The number of sessions viewed was negatively associated with changes in internalized homophobia (β=–.06; PP CONCLUSIONS DHI engagement is linked to participants’ sociodemographic and online behaviors. Given the importance of intervention engagement in the intervention’s effectiveness, DHIs with personalized intervention components that consider the individuals’ differences could increase the overall engagement and efficacy of DHIs.

Weight gain after breast cancer (BC) diagnosis is a well-known phenomenon; however, it is not a universal phenomenon and identification of patients at highest risk for weight gain is needed. This study investigates weight trajectories in early BC patients at 2 years post-primary treatment, examining potential contributing factors such as age, race, and receipt of chemotherapy, anti-HER-2 therapy, and endocrine treatment (ET).A single institution cohort of newly diagnosed women age 21 and older with early breast cancer patients (Stage 0-3) were identified by retrospective chart review (diagnosis year 1995 to 2016). Log-binomial regression models for net weight changes at 2 years post-primary treatment including patient demographic, clinical, and treatment characteristics.The final sample of 625 patients included 29% who were non-White and 37% who were pre-menopausal at diagnosis. Body mass index (BMI) at diagnosis was calculated and found to be normal in 33% (BMI 18 to 25), overweight in 27% (BMI 25 to 30), and obese in 40% (BMI 30 and higher). At 2 years, compared to weight at diagnosis, 31% had lost 2 kg, 34% had stable weight ± 2 kg, and 35% had gained 2 kg. Factors associated with 2 kg weight gain were menopausal status (pre-menopausal HR 1.65, 95% CI 1.34-2.04, p .0001), receiving any chemotherapy (HR 1.36, 95% CI 1.04-1.77), and anthracycline-based chemotherapy followed by ET (HR 1.60, CI 1.01-2.45). Anti-HER-2 therapy and transition from pre- to post-menopausal during the 2-year study period were not significant factors in weight gain. In multivariate analysis, menopausal status remained the only significant variable related to weight gain when adjusted for treatment. For all treatment combinations, pre-menopausal women had significantly more weight gain.Weight gain, weight loss, and stable weight in women with early breast cancer vary greatly by treatment plan. However, pre-menopausal patients have the highest risk for weight gain.

Establishing accurate estimates of physical activity at baseline is essential for interventions assessing the potential benefits of exercise in adults with cancer. This study compares self-reported physical activity with independent data from activity trackers in women with early breast cancer (BC) recruited into a “walking” intervention during chemotherapy. Baseline (pre-intervention) questions inquired about self-reported physical activity—number of walking days/week and minutes/day—in women who were initiating chemotherapy for Stage I–III BC. Activity trackers measured steps per day during the first full week of chemotherapy. Weighted Kappa statistic and Pearson correlation coefficients were used to evaluate agreement and association between self-reported and objectively tracked physical activity levels, respectively. Univariate analyses were conducted to identify variables that may influence congruence between the two measures. In a sample of 161 women, 77% were white, with mean age 56 years. Agreement between self-reported and objectively tracked physical activity was “fair” (kappa coefficient = 0.31), with most patients (59%) over-reporting their physical activity levels. There was weak correlation between the two measures (r = 0.24); however, correlation was strong in participants who were not married (r = 0.53) and/or living alone (r = 0.69). Objective methods for assessing physical activity (activity trackers, accelerometers) should be used as a complement to self-reported measures to establish credible activity levels for intervention studies seeking to increase physical activity and/or measure the impact of increased physical activity in women with breast cancer.

For minimizing patient inconvenience caused by intraoral sensor discomfort and unnecessary radiational exposure of diagnosis of dental caries, we developed a new system that insert the x-ray source tube (diameter: 3 mm, tube voltage: ~ 55 kV, tube current: ~ 300 uA) inside of the oral cavity and placed the the radiation acquisition device outside. The purpose of this study was to investigate the optimal acquisition conditions for the diagnosis of dental caries and to evaluate the image performance of the new intraoral x-ray imaging system. The 33 model sets were made with 3 teeth were randomly selected from 99 extracted human teeth, total of 5 conventional radiographic sets as control groups and 1 experimental set were prepared after cavity forming the 4 sites of artificial proximal caries(grade 1 to 4). Total 198 images were obtained and those were read by seven dentists of the grades and the correct answer rates were calculated and analyzed by one - way ANOVA. The new x-ray images were shown that there is no significant difference in reading for the diagnosis of proximal caries. Therefore the new x-ray system might be considerable for using in the clinical dental caries diagnosis, especially initial caries stage.

The South Korean government has banned sales of unhealthy foods in school stores since 2009; however, most school stores still sell restricted foods. This study aimed to understand the implementation processes and the reasons for incomplete implementation of the school nutrition policy in South Korea. Semi-structured interviews were conducted with 33 policy actors including school store owners, school staff, public officials, politicians, employees of food companies, and experts. Observations of foods sold in school stores were conducted. Interview transcripts were analyzed using both emergent codes and an a priori code list (participants, base values, perspectives, and effects) based on Lasswell’s social process model using NVivo 10. All interviewees perceived that school stores complied with the policy well; however, restricted foods were found in all interviewed school stores during the observations. Although all policy actors understood the intent of the policy; some of them were not interested in the policy or were unsatisfied with the policy and its outcomes such as profit loss. Perspectives and values towards the policy were different for each policy actor group. Poor monitoring of school store foods, lack of awareness of the policy, profit-seeking, and lack of interest in school stores were identified as reasons for incomplete implementation of the policy. The findings support the needs for consideration of various actors’ perspectives, especially for those who are affected by the policy, when implementing school nutrition policies. A stronger understanding of various actors’ involvement in policy processes can inform strategies to enhance implementation and thereby reach outcomes that align with the original policy intent.

BACKGROUND Gay, bisexual, and other men who have sex with men and transgender individuals are more heavily affected by HIV and other sexually transmitted infections (STIs) than their cisgender, heterosexual peers. In addition, sexual and gender minorities who use substances are often at a further increased risk of HIV and other STIs. Increasing testing for HIV and other STIs allows this hardly reached population to receive early intervention, prevention, and education. OBJECTIVE We explored HIV and STI testing patterns among 414 sexual and gender minority adolescents and young adults aged 15 to 29 years who self-reported substance use and lived in southeastern Michigan. METHODS We analyzed data from the baseline survey of a 4-arm randomized controlled trial that aimed to examine the efficacy of a brief substance use intervention for creating gains in engagement in HIV prevention. We fit multinomial logistic regression models to 2 categorical HIV and STI testing variables (lifetime and previous 12 months) based on self-reports of testing (never, STIs only, HIV only, or both). In addition, we compared HIV and STI testing behaviors across demographic characteristics, structural factors, psychosocial barriers, substance use, and sexual behaviors. RESULTS Our findings showed that 35.5% (147/414) of adolescents and young adults reported not being tested for either HIV or STIs in the previous year, and less than half (168/414, 40.6%) of the sample achieved the Centers for Disease Control and Prevention recommendation of HIV and STI testing once per year. We observed HIV and STI testing disparities across sociodemographic (eg, sexual identity, education, and income) and health (eg, substance use) correlates. Specifically, cisgender gay men who have sex with men were more likely to report being tested for HIV compared with bisexual men and transgender individuals, who were more likely to be tested for STIs. CONCLUSIONS This study illustrates the results of an HIV prevention intervention in southeastern Michigan showing the need for HIV prevention interventions that leverage structural factors, psychosocial barriers, and substance use as key drivers to achieve HIV and STI testing rates to meet the Centers for Disease Control and Prevention guidelines.

Relationships between heat shock protein 27 (HSP27) and cancer aggressiveness, metastasis, drug resistance, and poor patient outcomes in various cancer types including non-small cell lung cancer (NSCLC) were reported, and inhibition of HSP27 expression is suggested to be a possible strategy for cancer therapy. Unlike HSP90 or HSP70, HSP27 does not have an ATP-binding pocket, and no effective HSP27 inhibitors have been identified. Previously, NSCLC cancer cells were sensitized to radiation and chemotherapy when co-treated with small molecule HSP27 functional inhibitors such as zerumbone (ZER), SW15, and J2 that can induce abnormal cross-linked HSP27 dimer. In this study, cancer inhibition effects of NA49, a chromenone compound with better solubility, longer circulation time, and less toxicity than J2, were examined in combination with anticancer drugs such as cisplatin and gefitinib in NSCLC cell lines. When the cytotoxic drug cisplatin was treated in combination with NA49 in epidermal growth factor receptors (EGFRs) WT cell lines, sensitization was induced in an HSP27 expression-dependent manner. With gefitinib treatment, NA49 showed increased combination effects in both EGFR WT and Mut cell lines, also with HSP27 expression-dependent patterns. Moreover, NA49 induced sensitization in EGFR Mut cells with a secondary mutation of T790M when combined with gefitinib. Augmented tumor growth inhibition was shown with the combination of cisplatin or gefitinib and NA49 in nude mouse xenograft models. These results suggest the combination of HSP27 inhibitor NA49 and anticancer agents as a candidate for overcoming HSP27-mediated drug resistance in NSCLC patients.

Despite the disproportionate burden of HIV among Latinxs, there is a paucity of culturally appropriate interventions that have shown efficacy at increasing their engagement and retention in HIV care. We describe the development and implementation of Enlaces, a six-session, individual-level intervention, guided by the transnational framework, to improve HIV care outcomes for newly diagnosed and out-of-care Mexican men and transgender women (TW). Descriptive statistics summarizing baseline data and implementation outcomes are provided. 91 participants enrolled between October 2014 and August 2017. Intervention engagement and satisfaction was high; 81.3% completed all six sessions and 100% were very satisfied/satisfied with their experience. Successful implementation of the ENLACES intervention was the result of establishing client trust and maintaining a flexible, supportive approach to intervention delivery. Use of the transnational framework provided a contextualized approach to engaging with Mexican men and TW living with HIV that can be adapted to other Latino populations.

Sexual empowerment is a key strategy in HIV prevention intervention design, yet its measurement has been conceptualized as homogeneous. To date, no studies have examined whether young Black men who have sex with men (YBMSM) exhibit heterogeneity across sexual empowerment. Using baseline data from a randomized controlled trial (N = 275, HIV-negative YBMSM), we classified YBMSM into sexual empowerment profiles based on five indicators using a latent profile analysis and assessed the associations between the sexual empowerment profiles and stigma-related experiences using multinomial logistic regression. Three profiles were identified: psychologically empowered with safer sex intentions (profile 1); psychologically disempowered with safer sex intentions (profile 2); and psychologically disempowered without safer sex intentions (profile 3). YBMSM reporting fewer stigma-related experiences were more likely to be profile 1 than profile 2 and profile 3. To empower YBMSM, interventions based on sexual empowerment profile targeting the psychological/behavioral aspects of empowerment and addressing stigma are needed.

Approximately 5% of patients with IgA nephropathy (IgAN) exhibit mild mesangial lesions with acute onset nephrotic syndrome and diffuse foot process effacement representative of minimal change disease (MCD). It is not clear whether these unusual cases of IgAN with MCD (IgAN-MCD) are variant types of IgAN or coincidental deposition of IgA in patients with MCD. In a retrospective multicenter cohort study of 18 hospitals in Korea, we analyzed 46 patients with IgAN-MCD. Patients with endocapillary proliferation, segmental sclerosis, and crescent were excluded, and the clinical features and prognosis of IgAN-MCD were compared with those of pure MCD. In addition, we performed galactose-deficient IgA1 (KM55) staining to characterize IgAN-MCD. Among the 21,697 patients with glomerulonephritis enrolled in the database, 46 patients (0.21%) were diagnosed with IgAN-MCD, and 1610 patients (7.4%) with pure MCD. The 46 patients with IgAN-MCD accounted for 0.6% of primary IgAN patients (n = 7584). There was no difference in prognosis between patients with IgAN-MCD and those with only MCD. IgA and KM55 showed double positivity in all patients with IgAN-MCD (n = 4) or primary IgAN (n = 5) under double immunofluorescent staining. However, in four patients with lupus nephritis, mesangial IgA was deposited, but galactose-deficient-IgA1 (Gd-IgA1) was not. These findings suggest that IgAN-MCD is a dual glomerulopathy in which MCD was superimposed on possibly indolent IgAN. We confirmed by KM55 staining that IgAN-MCD is true IgAN, enabling better characterizations of the disease. Furthermore, IgAN-MCD shows a good prognosis when treated according to the usual MCD treatment modality.
