Vaping and Smoking Project in People With Schizophrenia

Although withdrawal is considered a key feature of nicotine/tobacco addiction that contributes to difficulty quitting smoking and likely electronic nicotine delivery systems (ENDS; e.g., electronic cigarettes), there is currently no research on ENDS withdrawal in people with schizophrenia. The proposed supplement will conduct a systematic and comprehensive characterization of withdrawal in a sample of people with SCZ who vape daily compared to those who smoke daily, filling gaps in our understanding of ENDS dependence/withdrawal for people with SCZ and contributing to the identification of intervention targets for ENDS use.

The Early Childhood Friendship Project - Phase 3

Vaping and Smoking Withdrawal Project

Withdrawal is a key, multi-faceted component of tobacco/nicotine dependence. Because withdrawal symptoms are theorized to drive relapse, facets of withdrawal (e.g., craving, negative affect) are the targets of most current and emerging treatments. Despite the central importance of withdrawal, and a voluminous literature on withdrawal from combustible cigarette smoking, little is known about withdrawal from electronic nicotine delivery systems (ENDS). To overcome critical barriers to progress in the field, the first-ever prospective, controlled comparison of abstinence-induced withdrawal between ENDS vapers and cigarette smokers is proposed. Participants will be 160 established daily vapers (including former smokers and dual users who smoke occasionally), 160 established daily smokers (including former vapers and dual users who vape occasionally), and (for exploratory comparisons) 50 established daily dual users, who smoke and vape daily. Participants will complete two 4-hour lab visits; the order of the ad lib use visit and the abstinent visit (which follows 24 hours of abstinence) will be randomized across participants. To advance knowledge of ENDS withdrawal, state-of-the-science, multi-measure, multi-method assessments of key withdrawal facets (negative affect, craving, difficulty concentrating, restlessness, sleep, and appetite, as well as anhedonia/positive affect and somatic effects) will be employed. For each facet, the hypothesis that withdrawal magnitude is lower among vapers compared to smokers will be tested. To inform theory and intervention development, the behavioral significance of ENDS withdrawal will also be evaluated, testing the hypotheses that abstinence will increase the motivation to vape/smoke and this group difference will be accounted for (mediated) by vaper/smoker differences in one or more withdrawal facets. Exploratory analyses will examine whether group differences in withdrawal are accounted for (mediate) by differential nicotine exposure, explore the role of individual differences (e.g., sex, rate of nicotine metabolism, expectancies), and examine differences among sub-groups of vapers. The impact of this much-needed, detailed characterization of withdrawal from ENDS is enhanced by the inclusion of a comparator of great public health significance, cigarette smoking. In addition, by characterizing the specific withdrawal facets that drive motivation to vape/smoke, the proposed work will identify promising intervention targets for subsequent treatment development efforts.

Leveraging Regulatory Flexibility for Methadone Take-Home Dosing to Improve Retention in Treatment for Opioid Use Disorder

Regulatory changes made during the COVID-19 public health emergency (PHE) that relaxed criteria for take- home dosing (THD) of methadone offer an opportunity to improve retention in care with a lifesaving treatment. Methadone is a highly effective medication for treating opioid use disorders (OUD) that is provided in opioid treatment programs (OTPs). Yet, longstanding regulatory restrictions limit the availability of methadone as well as create demands that heavily burden clients by requiring frequent visits to clinics. The rationale for these regulations is to safeguard against diversion and overdoses from methadone. Yet, the history and application of methadone regulations stem from stigmatized and racist notions of people with OUD. Most OTPs are located within communities with predominantly Black/African American or Latinx populations. Consequently, Black/African American and Latinx individuals have greater access to methadone than other, less restricted, medications for OUD. Within OTPs, Black/African American and Latinx individuals are less likely to receive adequate dosing levels of methadone and have lower retention than non-Hispanic White clients. More flexible THD may help address disparities in care. Currently, there is a national debate about balancing safety concerns over more flexible THD against the benefits of client retention and quality of life. Low offering of THD in many OTPs suggests a need for new data-driven interventions to encourage changes in engrained clinical workflows and long-standing stigmatizing beliefs about OUD clients. OTP leadership and staff express concern about misapplying regulatory flexibility, of iatrogenic effects of greater THD, and about legal liability from overdoses or diversion. Finally, financial concerns mount for organizations that have long based their business models on billing for frequent in-person medication dispensing. This project stems from a well-established academic-public partnership in New York State between the Office of Addiction Services and Supports (OASAS) and research collaborators from New York University, Cornell University, and the University of Connecticut. The investigators propose a two-part project to develop then test a multidimensional OTP intervention to address clinical decision making, regulatory confusion, legal liability concerns, capacity for clinical practice change, and financial barriers to THD. The intervention will include OTP THD specific dashboards drawn from multiple State databases. The approach will be informed by the Health Equity Implementation Framework. In year 1, the investigators will employ an explanatory sequential mixed method design to combine analysis of large state administrative databases-Medicaid, treatment registry, THD reporting-with qualitative interviews to refine the intervention. In years 2-5, the investigators will conduct a stepped-wedge trial with 36 OTPs (~10,800 Medicaid clients/yr) randomized to 6 cohorts of a six-month long clinic-level intervention over three years. The trial will test the effects of the intervention on 1) THD; 2) retention in care; and 3) adverse healthcare events. The investigators will specifically examine the effects of the intervention for Black/African American and Latinx clients.

Effect of Giving Reduced Fluid in Children After Trauma

Aggressive fluid resuscitation has been the cornerstone of early post-operative and trauma management for decades. However, recent prospective adult studies have challenged this practice, linking high volume crystalloid resuscitation to increased mortality, cardiopulmonary, gastrointestinal and hematologic complications. A retrospective study the investigators recently performed at their quaternary-care children's hospital echoed these results. High quality prospective data is necessary to determine best practice guidelines in our pediatric surgery and trauma patients. Currently, no standard exists to guide management of crystalloid fluid administration in trauma patients. Both liberal and restricted strategies are in use, dependent on physician discretion. The investigators propose the first randomized controlled trial (RCT) comparing a liberal to a restricted fluid management strategy in critically ill pediatric trauma patients. The objective of this comparative effectiveness study is to conduct a multicenter (around 10 sites) randomized controlled trial (RCT) to determine whether liberal or restricted fluid administration leads to better outcomes in these patients.

Safety and Effectiveness of the TENEO 317 Model 2 (1.28 US) Excimer Laser for Laser In Situ Keratomileusis (LASIK) Surgery to Treat Hyperopia With or Without Astigmatism

A Prospective Study to Evaluate the Raindrop Near Vision Inlay With Mitomycin C

The surgical procedure includes a low dose, short duration MMC treatment on the exposed stromal bed of the non-dominant eye, before the unilateral implantation of the corneal inlay. This treatment is at a concentration of 0.2 mg/mL (0.02%) applied for 10 to 30 seconds on the stromal bed as well as the stromal side of the corneal flap or pocket. In the third month after surgical procedure, one-drop a day of low dose steroid will be continued for the duration of the 24-month follow-up period to maintain corneal health.
