RESUMEN
Oxidative stress-mediated retinal pigment epithelial (RPE) cell damage is associated with age-related macular degeneration (AMD). ST266 is the biological secretome produced by a novel population of amnion-derived multipotent progenitor cells. Herein, we investigated the effect of ST266 on RPE cell injury induced by hydroquinone (HQ), a cigarette smoke related oxidant, hydrogen peroxide (H2O2) and all-trans retinal (atRal), a pro-oxidant component of the retinoid cycle. We additionally investigated its effect on Müller cell injury induced by H2O2. Cultured human RPE cells were pre-treated for 1 hour in the presence or absence of MK-2206, a protein kinase B (Akt) inhibitor, then treated with varying concentrations of HQ, H2O2, or atRal for 1.5 hours. Cultured human Müller cells (MIO-M1) were pre-treated for 1 hour in the presence or absence of MK-2206, then treated with varying concentrations of H2O2 for 1.5 hours. Media were then replaced with STM100 (control media into which the ST266 secretome proteins were collected) or ST266 at various times. Cell viability was determined with WST-1 reagent. Mitochondrial membrane potential (Δψm) was quantified by a fluorescence plate reader. The protein phosphorylation levels of Akt, glycogen synthase kinase 3 beta (GSK-3ß), and p70 ribosomal S6 kinase (p70S6K) were measured by Western blot. ST266 significantly improved RPE and MIO-M1 cell viability that was reduced by oxidant exposure and improved oxidant-disrupted Δψm. In both cell types, ST266 induced phosphorylation of Akt, GSK-3ß, and p70S6K. MK-2206 significantly eliminated ST266-mediated protein phosphorylation of Akt, GSK-3ß, and p70S6K and abolished the ST266-protective effect on cell viability. In conclusion, ST266 activates Akt, protects against oxidative stress-mediated cell injury in an Akt-dependent manner, and improves Δψm, suggesting a potential role for ST266 therapy in treating retinal diseases such as AMD.
RESUMEN
ABSTRACTAdolescents and young adults (young people) with HIV (YPWH) often struggle with treatment self-management. Many have symptoms due to HIV disease, medication side-effects, or comorbid conditions. Our study investigated the severity of HIV-related symptoms among YPWH aged 18-24 with detectable viral loads from an HIV clinic in Ghana (N = 60) and potential correlates of severity across a range of factors. Results indicated that YPWH currently experienced, on average, 13 symptoms (SD = 12.33). Six of the 10 most common symptoms were from two domains: fatigue and psychological. The most common symptoms were headaches (62%), weakness (53%), and fear/worries (52%). No differences were observed in number or severity of symptoms between youth based on HIV transmission status. Bivariate correlates of symptom severity were found with six that remained significant or approached significance in a multivariate model predicting severity: living with a parent/guardian, higher perceived access to HIV care, and higher treatment readiness were associated with lower severity while greater travel time to the HIV clinic, psychological distress, and more missed clinic appointments were associated with higher severity. Our findings suggest that interventions to address symptoms among YPWH should be multilevel and include strategies (e.g., telehealth, home care) to increase access to care.

OBJECTIVES: Prolonged antibiotic use after birth is associated with neonatal feeding intolerance and functional gastrointestinal disorders (FGIDs). A gastric dysrhythmia (tachygastria) with frequencies >4-9 cycles per minute, measured by electrogastrography (EGG), is associated with FGIDs. The relationship between prolonged antibiotic use and % time spent in tachygastria is unknown in preterm infants. We aimed to compare weekly changes in % tachygastria between preterm infants receiving long (>48 h) versus short (≤48 h) courses of antibiotics for early onset sepsis evaluation (initiated at <3 days of life). METHODS: This was a longitudinal, prospective cohort study of 88 preterm infants (<34 weeks' gestation) with weekly EGG recordings from the first week of life until 40 weeks' post-menstrual age, discharge, or death. We calculated % of EGG recording time in tachygastria and determined the mean across weekly sessions. A mixed effects model assessed variance in % tachygastria between the short- and long-antibiotic exposure groups across all weeks. RESULTS: Baseline characteristics were similar between the two groups. There was no difference in % tachygastria between short and long antibiotic exposure groups across nine postnatal weeks (p = 0.08). CONCLUSIONS: Early, prolonged antibiotic exposure among preterm infants may not lead to significant gastric dysrhythmia. Future studies including larger sample sizes and a "no antibiotic" exposure arm are essential in elucidating this potential relationship.
RESUMEN
Antiretroviral pre-exposure prophylaxis (PrEP) is highly effective in preventing HIV. Despite its promise, PrEP use is low, especially among young Black men who have sex with men (YBMSM). The prevalence of HIV in Mississippi (MS) is among the highest in the United States, with the bulk of new infections occurring amongst YBMSM living in Jackson, MS. We recruited 20 PrEP-eligible YBMSM and 10 clinic staff from MS health clinics between October 2021 and April 2022. Data were collected remotely using in-depth interviews and a brief survey, which lasted approximately 45-60 min. Interview content included PrEP knowledge/experiences, HIV risk perception, and PrEP use barriers and facilitators. Qualitative data were coded then organized using NVivo. Using thematic analysis methodology, data were assessed for current barriers to PrEP use. An array of barriers were identified by participants. Barriers included structural factors (cost of PrEP, lack of discreet clinics, time commitment, competing interests); social factors (unaware of HIV risk, stigma and homophobia, fear that partners would find out about PrEP use, not knowing anyone on PrEP); behavioral factors (sexual risk factors, denial, less priority for prevention vs treatment); and clinical factors (misunderstood side effects, fear PrEP won't work). Significant barriers to PrEP use among YBMSM stem from structural, social, behavioral, and clinical factors. These results will inform intervention efforts tailored to mitigate barriers and improve PrEP uptake among YBMSM in the southern United States.

BACKGROUND: The source and clearance of cytokines in the fetal circulation in term pregnancies complicated by chorioamnionitis remains unclear as are the contributions of placental transport, synthesis, and clearance. The objectives of the study were to determine (1) fetal and/or placental contributions to synthesis and/or clearance of inflammatory and anti-inflammatory cytokines in term pregnancies complicated by chorioamnionitis and (2) whether this differs in pregnancies further complicated by fetal hypoxia. METHODS: Prospective cohort study of pregnancies >37 weeks gestational age that included: Group 1, uncomplicated cesarean delivery without labor (n = 20); Group 2, uncomplicated vaginal delivery (n = 30); Group 3, pregnancies complicated by chorioamnionitis (n = 10); Group 4, complicated by chorioamnionitis + fetal hypoxia (n = 10). Umbilical arterial (UmA) and venous (UmV) blood were assayed for IL-1ß, IL-2, IL-6, IL-8, TNFα, and IL-10. RESULTS: IL-6 and IL-8 were below assay detection in UmA and UmV blood in Group 1 and increased in Group 2 (P < 0.01), UmA¼UmV (P < 0.01). Their concentrations increased further in Groups 3 and 4 (P = 0.003), UmA¼UmV. Placental clearance was concentration dependent that approaches saturation in the presence of chorioamnionitis. CONCLUSIONS: Marked increases in fetal synthesis of IL-6 and IL-8 occur in chorioamnionitis. Synthesis increase further when complicated by fetal hypoxia. Cytokine removal occurs via placental concentration-dependent mechanisms, potentially contributing to adverse fetal effects. IMPACT: The source and role of the placenta in synthesis and/or clearance of inflammatory mediators in term pregnancies complicated by clinical chorioamnionitis are unclear; however, conventional wisdom suggests the placenta is their source. This is the first study demonstrating that circulating concentrations of fetal IL-6 and IL-8 in clinical chorioamnionitis ± birth asphyxia in term pregnancies are of fetal origin. Circulating fetal inflammatory cytokines are cleared by concentration-dependent placental mechanisms that are nearly saturated in chorioamnionitis ± fetal hypoxia. These observations provide additional insight into understanding the fetal immune response in term pregnancies complicated by clinical chorioamnionitis.

Given their disproportionate HIV incidence, there is a critical need to identify factors related to HIV risk among Black young men who have sex with men (YMSM) in the southeastern United States. This study investigated the association of family factors and HIV-related outcomes among Black YMSM in Mississippi ages 14-20 (n = 72). Multivariable regression models evaluated associations of family factors and outcomes. Greater parent/child communication about sex was associated with fewer lifetime male sex partners and lower odds of lifetime anal sex. Greater parental monitoring was associated with greater likelihood of future condom use. Sexual orientation disclosure was associated with more lifetime male sex partners. Parental monitoring and parent/child communication about sex were protective, suggesting that family-based interventions are promising for HIV prevention among Black YMSM in Mississippi. Results also indicated that YMSM who are "out" to family are important to reach, and families could be useful in encouraging healthy behaviors.

Mississippi (MS) trails behind other states in both pre-exposure prophylaxis (PrEP) and COVID-19 vaccine uptake. This study investigated similarities in willingness to receive the COVID-19 vaccine and use PrEP. Semi-structured interviews were conducted between April 2021 and January 2022 with 15 clinical staff and 49 PrEP-eligible patients living in MS. Reflexive thematic analysis was conducted. Overall, 51% of patients were on PrEP, and 67% received the COVID-19 vaccine. Among PrEP users, 64% had received the vaccine. Participants reported similar hesitations (efficacy, side effects, and no perceived risk) and reasons for use (health autonomy and protecting themselves and others) regarding PrEP and the COVID-19 vaccine. Taking PrEP did not increase the likelihood of getting the COVID-19 vaccine, thus engaging in one prevention behavior does not lead to engaging in other prevention behaviors. However, results indicated commonalities in hesitancy and motivators to utilize both preventive measures. Future prevention and implementation efforts can be informed by these commonalities.

Pre-exposure prophylaxis (PrEP) is underutilized among Black men who have sex with men (BMSM) in the Southern United States. We assessed comfort receiving PrEP at various locations among 65 BMSM. Chi-square and t-tests explored associations between demographics, experienced homophobia and racism, and comfort receiving PrEP. BMSM with greater experienced homophobia were less comfortable at academically affiliated clinics [X2(2, N = 59) = 10.61, p = 0.01], CBOs [X2(3, N = 59) = 10.02, p = 0.02], and STI/HIV clinics [X2(3, N = 59) = 8.63, p = 0.04]. Those with greater experienced racism were more comfortable receiving PrEP by mail [X2(3, N = 61) = 9.40, p = 0.02]. Homophobia and racism influence preferences of BMSM for where and how they receive PREP care. Private modes of PrEP delivery and interventions targeting provider and organizational bias should be explored.

OBJECTIVE: As in many realms of academia and medicine, in obstetrics and gynecology, women experience gender bias in residency evaluations and academic promotions. More specifically, women in Maternal-Fetal Medicine (MFM) are underrepresented within departmental leadership positions. As a means of identifying spaces where bias may exist, multiple investigators have previously reported on gender bias in letters of recommendation (LORs) for residency and subspecialty training programs. We aimed to determine if linguistic differences exist in LORs for self-identified male and female applicants to MFM fellowship at an academic institution. STUDY DESIGN: This was a retrospective single-site cohort study from 2019 to 2021. Data collected included applicant's age, self-reported race/ethnicity and gender, geographic region of residency, step 1 and 2 scores, scholarly and volunteer activities, and number of LORs. The Linguistic Inquiry and Word Count (LIWC) software, a validated text analysis program, was used to characterize LOR linguistic content. Multivariable analysis was used to compare letter characteristics to applicant demographics. RESULTS: A total of 212 applications were reviewed, including 808 LORs. Women comprised 76.9% of applicants, and men 23.1%. Most applicants identified as non-Hispanic White (52.8%). Men were more likely to be international medical graduates (20 vs. 6%, p ≤ 0.01), and women reported more volunteer activities (7.1 ± 5.1 vs. 5.5 ± 4.3, p = 0.04). There were no differences in step scores, number of research projects, or number of LORs. Multivariable analysis controlling for applicant race, step 1 score, and gender of letter writer revealed that letters written for males contained significantly more references to the word category cognitive processes (7.4 ± 0.2 vs. 7.1 ± 0.1, p = 0.046), specifically in reference to the subcategories of certainty and differentiation. CONCLUSION: We identified linguistic differences in LORs written for MFM applicants, suggesting potential bias in the style of writing for male and female physicians applying to this field. KEY POINTS: · Gender bias exists in the evaluation and promotion of women in medicine.. · We sought to determine whether it also exists in letters of recommendation for MFM fellowship.. · Previous studies have examined gender bias in letters of recommendation for other specialties.. · Linguistic bias was detected in letters of recommendation for MFM fellowship from 2019 through 2021.. · We found evidence of linguistic differences based on gender of applicant and letter writers..
RESUMEN
OBJECTIVE: A ventricle-to-brain index (VBI) >0.35 is associated with low scores on the Bayley Scales of Infant and Toddler Development, Third Edition (BSID-III) in preterm infants with birth weight <1,250 g. However, VBI obtained at the third ventricle has only moderate interobserver reliability. The objective of this study was to test (1) reliability of VBI measured at the foramen of Monro on the latest ultrasonogram (US) before discharge using the intraclass correlation coefficient (ICC) and (2) the relationship between VBI and BSID-III scores at ≥18 months corrected age. STUDY DESIGN: The present study is a single-center retrospective cohort study. RESULTS: The study included 270 preterm infants born at 230/7 to 286/7 weeks of gestational age. The ICC of VBI between independent measurements by two study radiologists on the first 50 patients was 0.934. Factors associated with the value of VBI included severe intraventricular hemorrhage, bronchopulmonary dysplasia, and systemic steroid administration for BPD but not postmenstrual age. In multivariate analysis, VBI was negatively and independently associated with cognitive (p = 0.002), language (p = 0.004), and motor (p < 0.001) BSID-III scores. The association between VBI and BSID-III scores was observed even in infants in whom the latest US was obtained before term equivalent age. The association between VBI and BSID-III scores was also observed after excluding those with severe intraventricular hemorrhage. CONCLUSION: In this very preterm cohort the measurement of VBI had excellent reliability. Moreover, VBI measurements were negatively associated with motor, language, and cognitive BSID-III scores. KEY POINTS: · Mean values of VBI are stable with postmenstrual age.. · Values at the foramen of Monro are reliable and reproducible.. · VBI is negatively associated with Bayley scores.. · The association is observed even before term age..
RESUMEN
BACKGROUND: Human immunodeficiency virus (HIV) continues to be a concern in the United States despite pre-exposure prophylaxis (PrEP) being a highly recommended preventative option. Homeless populations have a significantly increased risk of HIV acquisition, and recent literature found attrition to PrEP care being concentrated in demographics common to these populations. Pharmacist-led PrEP programs may be a feasible option to combat this attrition, as they have shown high rates of patient satisfaction and pharmacist comfortability in other populations. OBJECTIVES: To evaluate PrEP uptake and the continuum of care before and after a Clinical Pharmacy Specialist (CPS) expanded HIV prevention services within a primary care setting for persons experiencing homelessness. METHODS: We compared a retrospective cohort of patients experiencing homelessness who received an initial PrEP prescription during a pre-CPS period and those with an initial PrEP prescription after CPS. Charts were reviewed through the surrounding time period of a 3-month and a 6-month PrEP follow-up appointment. Outcomes evaluated included number of initial PrEP prescriptions, dispensations of PrEP, PrEP discontinuations, patient retention in PrEP care, and new HIV diagnoses. RESULTS: A total of 40 patients were included, with 10 initial PrEP prescriptions in the pre-CPS population and 30 in the post-CPS one. Both groups largely represented those disproportionately impacted by HIV. After CPS, more patients were enrolled in patient assistance programs (100% vs. 44%; P < 0.01), and more patients picked up the first PrEP dispensation (80% vs. 40%; P = 0.04). The overall population had low dispensation rates and retention to care. Having no CPS management and a lack of medical appointment attendance trended toward attrition of care, and having no patient assistance program enrollment significantly led to attrition of care. CONCLUSION: These findings may prompt further studies and adaptations to PrEP care among persons experiencing homelessness, including the utilization of pharmacists to improve patient outcomes.

Necrotizing enterocolitis (NEC) is the leading cause of death from gastrointestinal disease in premature infants and is steadily rising in frequency. Patients who develop NEC have a very high mortality, illustrating the importance of developing novel prevention or treatment approaches. We and others have shown that NEC arises in part from exaggerated signaling via the bacterial receptor, Toll-like receptor 4 (TLR4) on the intestinal epithelium, leading to widespread intestinal inflammation and intestinal ischemia. Strategies that limit the extent of TLR4 signaling, including the administration of amniotic fluid, can reduce NEC development in mouse and piglet models. We now seek to test the hypothesis that a secretome derived from amnion-derived cells can prevent or treat NEC in preclinical models of this disease via a process involving TLR4 inhibition. In support of this hypothesis, we show that the administration of this secretome, named ST266, to mice or piglets can prevent and treat experimental NEC. The protective effects of ST266 occurred in the presence of marked TLR4 inhibition in the intestinal epithelium of cultured epithelial cells, intestinal organoids, and human intestinal samples ex vivo, independent of epidermal growth factor. Strikingly, RNA-seq analysis of the intestinal epithelium in mice reveals that the ST266 upregulates critical genes associated with gut remodeling, intestinal immunity, gut differentiation. and energy metabolism. These findings show that the amnion-derived secretome ST266 can prevent and treat NEC, suggesting the possibility of novel therapeutic approaches for patients with this devastating disease.NEW & NOTEWORTHY This work provides hope for children who develop NEC, a devastating disease of premature infants that is often fatal, by revealing that the secreted product of amniotic progenitor cells (called ST266) can prevent or treat NEC in mice, piglet, and "NEC-in-a-dish" models of this disease. Mechanistically, ST266 prevented bacterial signaling, and a detailed transcriptomic analysis revealed effects on gut differentiation, immunity, and metabolism. Thus, an amniotic secretome may offer novel approaches for NEC.

Young people living with HIV (YPLH) are at risk for poor treatment adherence. Short message service (SMS) interventions can improve adherence, yet few exist for YPLH. Our study investigated preferences for a game-based SMS intervention among YPLH in Ghana. Thirty-two YPLH, ages 18 to 24, were recruited from an HIV clinic to complete in-depth interviews. Content analysis of interview data revealed areas of technology use relevant to intervention implementation, including mobile communication preferences, internet access, and mobile game use. Participants reported high perceived utility towards intervention features: treatment reminders, gamification components, and involvement of supportive individuals (e.g., providers). Issues with privacy, literacy, and cultural/developmental appropriateness were among concerns raised. Suggestions were made for strengthening basic SMS features (e.g., using code words to protect privacy) and incorporating advanced features (e.g., simplifying game interactions). This novel approach may help engage YPLH in HIV care if carefully developed with attention towards its mechanisms and user preferences.

OBJECTIVES: Tachygastria is a gastric dysrhythmia (>4 to ≤9 cycles per minute, cpm) associated with gastric hypomotility and gastrointestinal disorders. Healthy preterm infants spend more time in tachygastria than adults; however, normative values are not defined. We sought to determine the percent of time preterm infants spend in tachygastria. METHODS: We conducted a longitudinal, prospective cohort study with weekly electrogastrography (EGG) recordings in 51 preterm <34 weeks' gestation and 5 term (reference) infants. We calculated percentage recording time in tachygastria (% tachygastria) and determined the mean ± standard deviation (SD) across EGG sessions. Mixed effects model was performed to test weekly variance in % tachygastria and gestational age effect. Successive pre- and post-prandial measurements were obtained to assess reproducibility of % tachygastria. We compared time to achieve full feeds between subjects with % tachygastria within 1 SD from the mean versus % tachygastria >1 SD from mean. RESULTS: Three hundred seventy-six EGG sessions were completed (N = 56). Mean % tachygastria was 40% with SD ±5%. We demonstrated no change in % tachygastria across 9 postnatal weeks (P = 0.70) and no gestational age effect. No difference was demonstrated between successive pre- (P = 0.91) and post-prandial (P = 0.96) % tachygastria. Infants with 35%-45% tachygastria (within 1 SD from mean) had higher gestational age and less time to achieve full feeds than infants with <35% or >45% tachygastria. CONCLUSIONS: EGG is a reproducible tool to assess % tachygastria in preterm infants. Clinical significance of increased or decreased % tachygastria needs further investigation to validate if 35%-45% tachygastria is safe for feeding.

Endowing meta-analytic results with a causal interpretation is challenging when there are differences in the distribution of effect modifiers among the populations underlying the included trials and the target population where the results of the meta-analysis will be applied. Recent work on transportability methods has described identifiability conditions under which the collection of randomized trials in a meta-analysis can be used to draw causal inferences about the target population. When the conditions hold, the methods enable estimation of causal quantities such as the average treatment effect and conditional average treatment effect in target populations that differ from the populations underlying the trial samples. The methods also facilitate comparison of treatments not directly compared in a head-to-head trial and assessment of comparative effectiveness within subgroups of the target population. We briefly describe these methods and present a worked example using individual participant data from three HIV prevention trials among adolescents in mental health care. We describe practical challenges in defining the target population, obtaining individual participant data from included trials and a sample of the target population, and addressing systematic missing data across datasets. When fully realized, methods for causally interpretable meta-analysis can provide decision-makers valid estimates of how treatments will work in target populations of substantive interest as well as in subgroups of these populations.

Background: The clinical effectiveness of audio-only telemedicine has not been fully quantified. The pandemic afforded a unique situation to retrospectively observe clinical outcomes of care for three disease cohorts within three care models, including audio-only telemedicine. Methods: Patients were classified into three care models: audio-only telemedicine, in-person, and hybrid. Each model was compared with an aggregate group before the onset of the pandemic and within each group during the pandemic. Each disease cohort was evaluated in cross-sectional and paired analyses. Results: Patients (n = 52,720) were grouped within one of three care models. A majority (n = 48,335) of patients qualified for the "pre" group comparison. The audio-only telemedicine care model showed similar control of renal disease, hypertension control, and diabetes management than in-person and hybrid care models. Conclusions: Audio-only telemedicine appears to be noninferior to in-person or hybrid models for chronic disease management for the diseases studied. In all instances, it had similar control compared with the in-person care model. We acknowledge the limitations of this study, including convenience sampling and a limited observation timeframe. Audio-only telemedicine should be considered a viable care model modality that can be integrated into options for patient care. Further study and investment are warranted, as it provides efficacy and convenience to health systems (Clinical Registration Number # 32449).

OBJECTIVE: Cannabis use disorder (CUD) is associated with an elevated risk for psychiatric disorders and symptoms, contributing to poor health outcomes and increased medical costs. Unfortunately, interventions that simultaneously address cannabis use and co-occurring psychiatric disorders are limited in availability. Targeted digital interventions to reduce cannabis use could be beneficial for patients with psychiatric disorders. Digital interventions could be easily disseminated and used in numerous clinical locations, including outpatient, inpatient, residential, and community psychiatric treatment settings. METHODS: Literature on digital cannabis reduction interventions for persons with psychiatric disorders was examined between April 2021 and June 2021. Articles were obtained from PubMed and PsycINFO databases. English language randomized controlled trials (RCT), feasibility and acceptability studies, pilot studies, and published protocols were included. RESULTS: There is significant evidence that digital interventions can effectively reduce cannabis use in general, non-clinical populations. However, there is less literature examining interventions for persons living with co-occurring psychiatric illness-most of which is tailored to patients living with chronic psychosis. CONCLUSIONS: There is great need for accessible and tailored digital interventions for co-occurring CUD and psychiatric disorders.

Objectives: We examined the prevalence of sexting, related motivations, demographics, and association with behavioral health problems among justice-involved adolescents. Hypotheses: We hypothesized positive associations between sexting and sexual risk, substance use, delinquency, and mental health problems. Methods: Participants were 307 community-supervised justice-involved adolescents with a first-time offense (Mage =14.50 years, 44.6% female) and their caregivers. Adolescents answered questions on technology use and sexting by sending, receiving, or forwarding sexually suggestive text messages and images (pictures or videos). They also completed measures of recent (past 4-month) sexual activity, unprotected sex, cigarette, alcohol, marijuana, and other drug use, and delinquency; current trauma symptoms, internalizing problems, and adaptive functioning. Results: Prevalence of sexting were 37.7% (lifetime overall; 17.0% sent texts; 17.4% sent images) and 29.5% (past-year overall; 12.8% sent texts; 13.6% sent images). Sexts were commonly sent as presents to partners, in response to sexts received, or to have fun. "Sexters" were older than "non-sexters" and more likely to identify as lesbian, gay, bisexual, or questioning. Past-year sexting was significantly associated with recent sexual activity; unprotected sex; alcohol use and days of use; marijuana and other drug use; delinquency and variety of delinquent acts; and elevated trauma symptoms and internalizing problems. Conclusions: Sexting is prevalent among adolescents with a first-time offense and co-occurs with multiple behavioral health needs. Intervention for this population may be informed by routinely assessing sexting in community settings. Familiarity with local reporting laws could help clinicians navigate the legal implications of sexting among adolescents with existing justice-system involvement.
RESUMEN
PURPOSE OF REVIEW: Adherence to antiretroviral treatment (ART) is crucial for the successful treatment of HIV. Unfortunately, it is estimated that 45% of persons living with HIV (PLWH) have poor adherence to ART. To provide health care professionals and PLWH with effective tools for supporting adherence, researchers have investigated the effectiveness of psychosocial interventions to enhance adherence to ART. In this paper, interventional studies, systematic reviews, and meta-analyses that examine ART adherence interventions for PLWH are reviewed. RECENT FINDINGS: There is great variability among interventions in terms of quality, sample, measures, and outcome characteristics. Despite a diverse and wide-ranging assortment of ART adherence interventions, consistent lessons have been learned. Interventions that focus on individual and interpersonal factors have been effective for improving ART adherence; however, the improvement in adherence tends to be short-lived. Additionally, interventions are most successful when tailored to those at risk for poor adherence. Finally, theory-based interventions are more likely to be effective than non-theory-based interventions. A variety of individual-level psychological interventions have been shown to be effective in improving ART adherence in the short term. Digital and mobile interventions have the potential to improve dissemination and implementation of these evidence-based interventions and could be used to extend intervention effects. Future interventions that address issues of accessibility, inequality, structural and institutional barriers to ART adherence should also be tested and prioritized. Implementation science frameworks can be used to assess and address issues of accessibility and systematic barriers to care.

Many estuarine ecosystems and the fish communities that inhabit them have undergone substantial changes in the past several decades, largely due to multiple interacting stressors that are often of anthropogenic origin. Few are more impactful than droughts, which are predicted to increase in both frequency and severity with climate change. In this study, we examined over five decades of fish monitoring data from the San Francisco Estuary, California, USA, to evaluate the resistance and resilience of fish communities to disturbance from prolonged drought events. High resistance was defined by the lack of decline in species occurrence from a wet to a subsequent drought period, while high resilience was defined by the increase in species occurrence from a drought to a subsequent wet period. We found some unifying themes connecting the multiple drought events over the 50-yr period. Pelagic fishes consistently declined during droughts (low resistance), but exhibit a considerable amount of resiliency and often rebound in the subsequent wet years. However, full recovery does not occur in all wet years following droughts, leading to permanently lower baseline numbers for some pelagic fishes over time. In contrast, littoral fishes seem to be more resistant to drought and may even increase in occurrence during dry years. Based on the consistent detrimental effects of drought on pelagic fishes within the San Francisco Estuary and the inability of these fish populations to recover in some years, we conclude that freshwater flow remains a crucial but not sufficient management tool for the conservation of estuarine biodiversity.
