In Drosophila, pairing of maternal and paternal homologous chromosomes can permit trans-interactions between enhancers on one homolog and promoters on another, an example of transvection. Although trans-interactions have been observed at many loci in the Drosophila genome and in other organisms, the parameters that govern enhancer action in trans remain poorly understood. Using a transgenic reporter system, we asked whether enhancers and promoters at nonallelic, but nearby, genomic positions can communication in trans. Using one transgenic insertion carrying the synthetic enhancer GMR and another nearby insertion carrying the hsp70 promoter driving a fluorescent reporter, we show that transgenes separated by 2.6 kb of linear distance can support enhancer action in trans at the 53F8 locus. Furthermore, transvection between the nonallelic insertions can be augmented by a small deletion flanking one insert, likely via changes to the paired configuration of the homologs. Subsequent analyses of other insertions in 53F8 that carry different transgenic sequences demonstrate that the capacity to support transvection between nonallelic sites varies greatly, suggesting that factors beyond the linear distance between insertion sites play an important role. Finally, analysis of transvection between nearby nonallelic sites at other genomic locations shows evidence of position effects, where one locus supported GMR action in trans over a linear distance of over 10 kb, whereas another locus showed no evidence of transvection over a span <200 bp. Overall, our data demonstrate that transvection between nonallelic sites represents a complex interplay between genomic context, interallelic distance, and promoter identity., Competing Interests: Conflicts of interest The author(s) declare no conflicts of interest., (© The Author(s) 2023.

People may use nonprescribed substances during an acute hospitalization. Hospital policies and responses can be stigmatizing, involve law enforcement, and lead to worse patient outcomes, including patient-directed discharge. In the United States, there is currently little data on hospital policies that address the use of substances during hospitalization. In this cross-sectional study, we surveyed clinicians at US hospitals with Accreditation Council of Graduate Medical Education (ACGME)-accredited addiction medicine fellowships about their current practices and policies and what they would include in an ideal policy. We had 77 responses from 55 out of 86 ACGME-addiction medicine fellowships (63.9%). Respondents identified policies at 21.8% of the institutions surveyed. Current responses to inpatient substance use vary, though most do not match what clinicians identify as an ideal response. Our results suggest that the use of nonprescribed substances during a hospitalization may be common, but a majority of hospitals likely do not have patient-centered policies to address this., (© 2023 Society of Hospital Medicine.)

Phenomenon: Many academic medical centers (AMCs) have a history of separating patients on the basis of insurance status. In New York State, where Black and Latino patients are more than twice as likely to have Medicaid as white patients, this practice leads to de facto racial segregation in healthcare. Emerging evidence suggests that this segregation of care is detrimental to both patient care and medical education. Medical students are uniquely positioned to be change makers in this space but face significant barriers to speaking out about these disparities and successfully advocating for institutional change. Approach: The authors designed, piloted, and distributed a 16-item survey on segregated care to third-year medical students at a large academic medical center in New York City. Students were asked both open- and close-ended questions about witnessing separation and differences in patient care on the basis of insurance during their clinical rotations. The survey was shared with 140 students in March 2019 with a response rate of 46.4% (n = 65). Preliminary findings were presented to school and hospital administrators. Findings: More than half of survey respondents reported witnessing separation of patient care or differences in patient care on the basis of insurance (56.3%, n = 36 and 51.6%, n = 33 respectively). Many students reported that these experiences contributed to cynicism and burnout. The authors leveraged these results to advocate for quality improvement measures. In Ob-Gyn, department leadership launched a clinical transformation taskforce and recruited a new Vice Chair of Clinical Transformation/Chief Patient Experience Officer, whose role includes addressing segregated care and disparities in health outcomes. The hospital committed to establishing integrated practices in new clinical spaces and launching a similar survey among house staff. Insights: Many medical students experience and participate in segregated care during their clerkships and this has the potential to impact their education. Medical students are well-positioned to recognize segregated care across health systems and leverage their experiences for advocacy. A survey-based approach can be a powerful tool enabling students to collect these experiences to address segregated care and other health equity issues.

There are currently more adults age fifty-five or older incarcerated in the United States than ever before. Little is known about the epidemiology or health care needs of geriatric patients in jails, where the majority of the population is being held in pretrial detention. We performed a retrospective analysis of electronic health record data to characterize the demographics, health conditions, and health care use of people age fifty-five or older who were incarcerated in the New York City jail system between 2015 and 2019. People in this age group accounted for 4 percent of admissions to the jails in 2009, ten years before the study's end date; 7 percent of admissions in 2015, when the study began; and 8.5 percent of admissions by 2019. They were more likely to report being homeless; suffer from a serious mental illness designation; carry a higher burden of chronic, infectious, and serious medical illnesses; be hospitalized during their incarceration; and die in jail custody than their younger counterparts. All elements of the criminal justice system need to be attuned to the vulnerabilities of this group, implement targeted interventions to divert them from incarceration when possible, and minimize harms for those who end up incarcerated.

Background: The co-occurrence of the COVID-19 pandemic and opioid epidemic has increased the risk of overdose and death for patients with opioid use disorder (OUD). COVID-19 has also exacerbated already limited access to opioid overdose education and naloxone distribution (OEND). In this context, we aim to increase access to OEND for patients at risk for opioid overdose. Methods: Medical student volunteers were trained to conduct telephone-based OEND, and subsequently contacted all patients at a NYC primary care clinic for people who use drugs as well as those presenting to the hospital with OUD or a history of opioid overdose. Interested patients who completed the training received naloxone kits via mail or at hospital discharge. Results: OEND provision was converted to a remote-only model from May to June 2020. During this time, eight pre-clinical medical students called a total of 503 high-risk patients. Of these patients, 165 were reached, with 90 (55%) accepting telephone-based OEND. Comparing across populations, 51% of primary care patients versus 76% of ED/hospitalized patients accepted opioid overdose education. Eighty-four total patients received naloxone. Conclusions: We have outlined a scalable, adaptable model by which clinics and hospitals with affiliated medical schools can provide OEND by telephone. Medical student-driven, telephone-based OEND efforts can effectively reach at-risk patients and increase naloxone access.

Background: In 2017, The Respectful and Equitable Access to Comprehensive Healthcare (REACH) Program at Mount Sinai Hospital became a registered Opioid Overdose Prevention Program (OOPP) and received funding from the New York City Department of Health and Mental Hygiene to develop a program to provide overdose education and naloxone distribution (OEND) training to at risk population and bystanders. We report on the programmatic quality improvement initiatives conducted. Methods: From April 2017 to December 2020, the REACH OOPP conducted 290 opioid overdose reversal trainings, throughout the Mount Sinai Health System and in multiple other community settings. OEND training was at times offered alone and in other settings alongside Hepatitis C Virus point of care testing. Additionally, a "train the trainer" model was implemented whereby medical students and nurses at outpatient clinics were trained to train others. Results: There were 4235 naloxone kits distributed to 3,906 participants. The training venues included hospital settings (patients and medical staff), public events, substance use programs, educational facilities, homeless prevention programs, faith-based organizations, alternative to incarceration programs, and community-based organizations. We implemented two types of training. During outreach sessions, we utilized one-on-one personalized sessions to train bystanders. When training clinic staff in the "train the trainer" model we utilized a standardized didactic presentation with slides. The two top reasons participants reported for being trained were "Just in case I see someone overdose" (59.3%) and "I'm worried that someone I know will overdose OR that I will overdose" (20.2%). Conclusion: The REACH program at Mount Sinai Hospital developed an effective model to train community bystanders and health care staff by leveraging administrative support and building on broader programmatic initiatives to promote drug user health and stigma-free care for people who use drugs. Hospitals do not currently mandate staff training or keeping naloxone stocked at inpatient units or outpatients clinics posing a challenge when implementing an OEND program in this setting. A recommended policy change needed to decrease overdose deaths is for hospitals to be required to implement systematic naloxone education and access for all health care personal and at risk patients., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2021 Riazi, Toribio, Irani, Hughes, Huxley-Reicher, McBratney, Vu, Sigel and Weiss.)

Problem: In accordance with guidelines from the Association of American Medical Colleges, medical schools across the United States suspended clerkships and transitioned preclinical courses online in March 2020 because of the COVID-19 pandemic. Hospitals and health systems faced significant burdens during this time, particularly in New York City., Approach: Third- and fourth-year medical students at the Icahn School of Medicine at Mount Sinai formed the COVID-19 Student WorkForce to connect students to essential roles in the Mount Sinai Hospital System and support physicians, staff members, researchers, and hospital operations. With the administration's support, the WorkForce grew to include over 530 medical and graduate students. A methodology was developed for clinical students to receive elective credit for these volunteer activities., Outcomes: From March 15, 2020, to June 14, 2020, student volunteers recorded 29,602 hours (2,277 hours per week) in 7 different task forces, which operated at 7 different hospitals throughout the health system. Volunteers included students from all years of medical school as well as PhD, master's, and nursing students. The autonomous structure of the COVID-19 Student WorkForce was unique and contributed to its ability to quickly mobilize students to necessary tasks. The group leaders collaborated with other medical schools in the New York City area, sharing best practices and resources and consulting on a variety of topics., Next Steps: Going forward, the COVID-19 Student WorkForce will continue to collaborate with student leaders of other institutions and prevent volunteer burnout; transition select initiatives into structured, precepted student roles for clinical education; and maintain a state of readiness in the event of a second surge of COVID-19 infections in the New York City area., (Copyright © 2020 by the Association of American Medical Colleges.)

With the opioid overdose mortality rates rising nationally, The New York City Department of Health and Mental Hygiene (NYC DOHMH) has worked to expand overdose rescue training (ORT) and naloxone distribution. This study sought to determine rates of overdose witnessing and naloxone use among overdose rescue-trained visitors to the NYC jails on Rikers Island. We conducted a six-month prospective study of visitors to NYC jails on Rikers Island who received ORT. We collected baseline characteristics of study participants, characteristics of overdose events, and responses to witnessed overdose events, including whether the victim was the incarcerated individual the participant was visiting on the day of training. Bivariate analyses compared baseline characteristics of participants who witnessed overdoses to those who did not, and of participants who used naloxone to those who did not. Overall, we enrolled 283 participants visiting NYC's Rikers Island jails into the study. Six months after enrollment, we reached 226 participants for follow-up by phone. 40 participants witnessed 70 overdose events, and 28 participants reported using naloxone. Of the 70 overdose events, three victims were the incarcerated individuals visited on the day of training; nine additional victims were recently released from jail and/or prison. Visitors to persons incarcerated at Rikers Island witness overdose events and are able to perform overdose rescues with naloxone. This intervention reaches a population that includes not only those recently released, but also other people who experienced overdose., (Copyright © 2017 Elsevier Ltd. All rights reserved.)

Background: Overdose deaths tripled between 1999 and 2014. Most fatal overdoses are witnessed, offering an opportunity for bystanders to call 911. However, fear of arrest may prevent them from calling authorities. Many states have passed 911 Good Samaritan laws that protects the 911 caller and overdose victim from prosecution for drug possession. Little is known, however, about whether the law affects 911-calling behavior of overdose witnesses. We investigated the relationship between knowledge of a 911 Good Samaritan Law (GSL) and 911-calling behavior of study participants trained in opioid overdose rescue., Methods: We enrolled 351 individuals (n = 351) trained in overdose rescue and educated about the New York State GSL in a prospective longitudinal study. Trained researchers conducted baseline, three, six and 12-month follow-up surveys with study participants to assess participant knowledge of the GSL and responses to witnessed overdoses., Results: At the twelve-month follow-up, participants had witnessed 326 overdoses. In the overdose events where the participant had correct knowledge of the GSL at the time of the event, the odds of a bystander calling 911 were over three times greater than when the witness had incorrect knowledge of the GSL (OR = 3.3, 95% CI, 1.4-7.5). This association remained significant after adjusting for age, gender, race of the witness and overdose setting (AOR = 3.6, 95% CI, 1.4-9.4)., Conclusions: To our knowledge, this is the first study to show an association between knowledge of the GSL and 911-calling behavior. Legislation that protects overdose responders along with public awareness of the law may be an effective strategy to increase rates of 911-calling in response to overdose events and decrease overdose-related mortality.

Background: Providing naloxone to laypersons who are likely to witness an opioid overdose is now a widespread public health response to the national opioid overdose epidemic. Estimating the proportion of individuals who use naloxone can define its potential impact to reduce overdose deaths at a population level. We determined the proportion of study participants who used naloxone within 12 months following training and factors associated with witnessing overdose and naloxone use., Methods: We conducted a prospective, observational study of individuals completing overdose prevention training (OPT) between June and September 2013. Participants were recruited from New York City's six largest overdose prevention programs, all operated by syringe exchange programs. Questionnaires were administered at four time points over 12 months. Main outcomes were witnessing or experiencing overdose, and naloxone administration., Results: Of 675 individuals completing OPT, 429 (64%) were approached and 351 (52%) were enrolled. Overall, 299 (85%) study participants completed at least one follow-up survey; 128 (36%) witnessed at least one overdose. Of 312 witnessed opioid overdoses, naloxone was administered in 241 events (77%); 188 (60%) by the OPT study participant. Eighty-six (25%) study participants administered naloxone at least once. Over one third of study participants (30, 35%) used naloxone 6 or more months after training., Conclusions: Witnessing an overdose and naloxone use was common among this study cohort of OPT trainees. Training individuals at high risk for witnessing overdoses may reduce opioid overdose mortality at a population level if sufficient numbers of potential responders are equipped with naloxone., (Copyright © 2017 Elsevier B.V.
