RESUMEN
Background: Delta-8 tetrahydrocannabinol (THC) has experienced significant cultivation, use, and online marketing growth in recent years.Objectives: This study utilized natural language processing on Twitter data to examine trends in public discussions regarding this novel psychoactive substance.Methods: This study analyzed the frequency of #Delta8 tweets over time, most commonly used words, sentiment classification of words in tweets, and a qualitative analysis of a random sample of tweets containing the hashtag "Delta8" from January 1, 2020 to September 26, 2021.Results: A total of 41,828 tweets were collected, with 30,826 unique tweets (73.7%) and 11,002 quotes, retweets, or replies (26.3%). Tweet activity increased from 2020 to 2021, with daily original tweets rising from 8.55 to 149. This increase followed a high-engagement retailer promotion in June 2021. Commonly used terms included "cbd," "cannabis," "edibles," and "cbdoil." Sentiment classification revealed a predominance of "positive" (30.93%) and "trust" (14.26%) categorizations, with 8.42% classified as "negative." Qualitative analysis identified 20 codes, encompassing substance type, retailers, links, and other characteristics.Conclusion: Twitter discussions on Delta-8 THC exhibited a sustained increase in prevalence from 2020 to 2022, with online retailers playing a dominant role. The content also demonstrated significant overlap with cannabidiol and various cannabis products. Given the growing presence of retailer marketing and sales on social media, it is crucial for public health researchers to monitor and promote relevant Delta-8 health recommendations on these platforms to ensure a balanced conversation.

OBJECTIVE: Online health communities (OHCs) have been identified as important outlets for social support and community connection for adolescents and young adults (AYAs) living with chronic illnesses. Despite evident benefits, there remains a gap in research on methods to maximize sustained patient engagement within OHCs. This study assessed per-patient daily commenting rates over time, as well as associations with program staff and volunteer-facilitated events and engagement. MATERIALS AND METHODS: We utilized data from 662 daily patient, volunteer, and staff comment totals within a Discord server hosted through the Streetlight at UF Health Streetlight Gaming and Online Team, between January 2019 and January 2022. Multilevel models were used to assess per-patient daily commenting rates and examine associations with OHC-level predictors of staff and volunteer-facilitated daily and seasonal events, as well as the number of daily active users. RESULTS: Per-patient comment rates showed an overall negative slope with time in most models. Unadjusted and adjusted growth curve models showed that daily events (ß = .21), seasonal events (ß = .18), and total daily active users (ß = .09) were all significantly associated with increases in per-patient daily comment rates. DISCUSSION: Results suggest that social event facilitation strategies can be applied to increase AYA patient engagement in OHCs. Seasonal events and staff and volunteer engagement may be the effective means of maintaining engagement among long-term patients. CONCLUSION: Our findings highlight the importance of staff and volunteer presence in OHCs in driving long-term patient engagement and in considering patient needs and perspectives in developing OHC features.

Background: Palliative care literature indicates a dearth of programs addressing the psychosocial needs of adolescents and young adults (AYAs). Objectives: This study assessed patient-reported experiences of a palliative care peer support program, analyzed psychometric qualities of the program evaluation, and examined associations with quality-of-life scores to assess validity and potential impact on aspects of AYA quality of life. Design: This retrospective, cross-sectional study described self-reported Streetlight program evaluation and quality of life of AYA patients, exploratory factor analysis of survey responses, and analysis of associations with quality of life. Setting/Subjects: AYA participants (13-30) enrolled in the Streetlight program for at least six months were recruited during hospital admissions and clinic visits at UF Health Shands Hospital. Results: Participants' (n = 69) scores were high for Youth Quality of Life Instrument-Short Form (YQOL-SF) (82.6 of 100), and Streetlight evaluations (4.47 of 5). Patients endorsed themes of: high-quality friendships with volunteers, transformative impacts to wellbeing, and benefits to mental health and coping in open-ended responses. Analyses identified three factors explaining 61% of variance in Streetlight program evaluation responses: "Friendships and Support" (26%); "Coping, Family, and Providers" (20%); and "Diversion and Respect" (15%). Significant positive associations were found between Streetlight evaluation scores and YQOL-SF Belief in Self and Family factor scores, as well as between Streetlight evaluation Friendships and Support factor scores, and YQOL-SF total and factor-specific scores. Conclusions: Results suggest that the Streetlight program is a viable model to facilitate positive experiences, opportunities for socialization, and meaningful peer support for AYA patients.

Objective: To conduct a social network analysis (SNA) of patient-volunteer networks and assess the impact of patient characteristics on network measures. Background: Volunteers play a critical role in providing peer support to adolescent and young adult (AYA) palliative care patients. Streetlight at UF Health is a peer support palliative care program for hospitalized AYAs that aims at forming positive peer relationships through volunteer visits, events, and a virtual online health community. Methods: Data were collected on patient characteristics, hospitalizations, average length of stays (LOS), and volunteer visitation records. Egocentric SNAs were conducted on each patient to calculate network outcomes. Study participants were AYA patients (N = 69), enrolled in the US-based Streetlight program at UF Health Shands Hospital. Results: The LOS was significantly associated with network size (B = 0.583; 95% confidence interval; CI [0.463 to 0.702]). Autoimmune patients had smaller network sizes when controlling for LOS. Total hospital admissions predicted - 0.172 ([- 0.263 to - 0.080]) lower average repeat visits. Higher average repeat visits were predicted for patients who had cancer (B = 0.246 [0.046 to 0.447]) and awaiting organ transplantation (B = 0.370 [0.082 to 0.658]). Although cystic fibrosis patients received more visits (B = 0.364 [0.003 to 0.724]) compared with other illness populations, the network density was lower (B = - 0.580 [1.01 to - 0.155]). Cancer patients had networks with a higher diversity in volunteer repeat visits (B = 0.714 [0.312 to 0.920]). Conclusions: Significant relationships between patient characteristics and network outcomes highlight the differences in social support service delivery among diverse populations. These analyses can be utilized in practice to guide program delivery for high-need patients.

BACKGROUND: The national opioid crisis has disproportionately burdened rural White populations and American Indian/Alaska Native (AI/AN) populations. Therefore, Cherokee Nation and Emory University public health scientists have designed an opioid prevention trial to be conducted in rural communities in the Cherokee Nation (northeast Oklahoma) with AI and other (mostly White) adolescents and young adults. Our goal is to implement and evaluate a theory-based, integrated multi-level community intervention designed to prevent the onset and escalation of opioid and other drug misuse. Two distinct intervention approaches-community organizing, as implemented in our established Communities Mobilizing for Change and Action (CMCA) intervention protocol, and universal school-based brief intervention and referral, as implemented in our established Connect intervention protocol-will be integrated with skill-based training for adults to strengthen social support for youth and also with strategic media. Furthermore, we will test systems for sustained implementation within existing organizational structures of the Cherokee Nation and local schools and communities. This study protocol describes the cluster randomized trial, designed to measure implementation and evaluate the effectiveness on primary and secondary outcomes. METHODS: Using a cluster randomized controlled design and constrained randomization, this trial will allocate 20 high schools and surrounding communities to either an intervention or delayed-intervention comparison condition. With a proposed sample of 20 high schools, all enrolled 10th grade students in fall 2021 (ages 15 to 17) will be eligible for participation. During the trial, we will (1) implement interventions through the Cherokee Nation and measure implementation processes and fidelity, (2) measure opioid and other drug use and secondary outcomes every 6 months among a cohort of high school students followed over 3 years through their transition out of high school, (3) test via a cluster randomized trial the effect of the integrated CMCA-Connect intervention, and (4) analyze implementation costs. Primary outcomes include the number of days during the past 30 days of (1) any alcohol use, (2) heavy alcohol use (defined as having at least four, among young women, or five, among young men, standard alcoholic drinks within a couple of hours), (3) any marijuana use, and (4) prescription opioid misuse (defined as "without a doctor's prescription or differently than how a doctor or medical provider told you to use it"). DISCUSSION: This trial will expand upon previous research advancing the scientific evidence regarding prevention of opioid and other drug misuse during the critical developmental period of late adolescent transition to young adulthood among a sample of American Indian and other youth living within the Cherokee Nation reservation. TRIAL REGISTRATION: ClinicalTrials.gov NCT04839978 . Registered on April 9, 2021. Version 4, January 26, 2022.

STUDY OBJECTIVE: Data from randomized controlled trials support a mortality benefit with ticagrelor versus clopidogrel among patients with acute myocardial infarction (AMI). Many healthcare providers preferentially treat patients with AMI with ticagrelor. The goal of this study was to determine the association between out-of-pocket drug costs and ticagrelor continuation compared with switching to clopidogrel among patients hospitalized for AMI, following a pharmacist-led discussion on outpatient co-payment costs for ticagrelor. DESIGN: Retrospective cohort study. SETTING: A tertiary care academic medical center. PATIENTS: Patients hospitalized with AMI between February 15, 2015 and January 23, 2017, who were loaded with ticagrelor on presentation. MAIN RESULTS: Of 143 patients with AMI loaded with ticagrelor, 70 (49%) switched to clopidogrel after cost discussion. The median monthly ticagrelor co-payment was $268.29 (interquartile range [IQR] $45-$350) for switchers, versus $18 (IQR $6-$24) for non-switchers (p<0.001). Patients with co-payments of $100/month or more were 3.4 times more likely to switch to clopidogrel (relative risk 3.41, 95% confidence interval 2.12 to 5.47), compared with patients with co-payments of less than $100/month. CONCLUSIONS: Following a discussion of outpatient costs, half of patients with AMI switched from ticagrelor to clopidogrel when given the choice.
RESUMEN
Col1a2-deficient (oim) mice synthesize homotrimeric type I collagen due to nonfunctional proα2(I) collagen chains. Our previous studies revealed a postnatal, progressive type I collagen glomerulopathy in this mouse model, but the mechanism of the sclerotic collagen accumulation within the renal mesangium remains unclear. The recent demonstration of the resistance of homotrimeric type I collagen to cleavage by matrix metalloproteinases (MMPs), led us to investigate the role of MMP-resistance in the glomerulosclerosis of Col1a2-deficient mice. We measured the pre- and post-translational expression of type I collagen and MMPs in glomeruli from heterozygous and homozygous animals. Both the heterotrimeric and homotrimeric isotypes of type I collagen were equally present in whole kidneys of heterozygous mice by immunohistochemistry and biochemical analysis, but the sclerotic glomerular collagen was at least 95-98% homotrimeric, suggesting homotrimeric type I collagen is the pathogenic isotype of type I collagen in glomerular disease. Although steady-state MMP and Col1a1 mRNA levels increased with the disease progression, we found these changes to be a secondary response to the deficient clearance of MMP-resistant homotrimers. Increased renal MMP expression was not sufficient to prevent homotrimeric type I collagen accumulation.

OBJECTIVE: We previously reported that inhibition or loss of CD26 (DPPIV/dipeptidylpeptidase IV) results in a defect in normal mobilization of hematopoietic stem and progenitor cells induced by granulocyte-colony stimulating factor (G-CSF). This suggests that CD26 is a necessary component of the mobilization pathway. Our goal in this study was to determine whether mobilization can be induced by the CXCR4 antagonist AMD3100 in mice lacking CD26 (CD26(-/-)). MATERIALS AND METHODS: Ten week old CD26(-/-) and C57BL/6 mice received a subcutaneous injection of AMD3100. One hour post-injection the mice were euthanized and peripheral blood and bone marrow were collected and evaluated. RESULTS: AMD3100 mobilizes hematopoietic progenitors into the peripheral blood of CD26(-/-) and mice. CONCLUSIONS: Our finding that AMD3100 rapidly mobilizes hematopoietic progenitor cells from the bone marrow into the periphery in CD26-deficient transgenic mice that otherwise exhibit a mobilization defect in response to G-CSF suggests that: (1) CD26 is downstream of G-CSF but upstream of the CXCL12-CXCR4 axis and (2) AMD3100 can be used as a single agent to mobilize hematopoietic stem and progenitor cells in normal donors or patients that have an intrinsic defect in their response to G-CSF treatment. Stem cell transplants are often the only curative treatment in some cancer patients. The ability to perform the transplantation and its success is dependent on the ability to mobilize adequate numbers of hematopoietic progenitor cells. The use of AMD3100 as a single agent would give patients or donors an additional option for a successful stem cell transplant.
