BACKGROUND:The large-scale social distancing efforts to reduce SARS-CoV-2 transmission have dramatically changed human behaviors associated with traumatic injuries. Trauma centers have reported decreases in trauma volume, paralleled by changes in injury mechanisms. We aimed to quantify changes in trauma epidemiology at an urban Level I trauma center in a county that instituted one of the earliest shelter-in-place orders to inform trauma care during future pandemic responses. METHODS:A single-center interrupted time-series analysis was performed to identify associations of shelter-in-place with trauma volume, injury mechanisms, and patient demographics in San Francisco, California. To control for short-term trends in trauma epidemiology, weekly level data were analyzed 6 months before shelter-in-place. To control for long-term trends, monthly level data were analyzed 5 years before shelter-in-place. RESULTS:Trauma volume decreased by 50% in the week following shelter-in-place (p < 0.01), followed by a linear increase each successive week (p < 0.01). Despite this, trauma volume for each month (March-June 2020) remained lower compared with corresponding months for all previous 5 years (2015-2019). Pediatric trauma volume showed similar trends with initial decreases (p = 0.02) followed by steady increases (p = 0.05). Reductions in trauma volumes were due entirely to changes in nonviolent injury mechanisms, while violence-related injury mechanisms remained unchanged (p < 0.01). CONCLUSION:Although the shelter-in-place order was associated with an overall decline in trauma volume, violence-related injuries persisted. Delineating and addressing underlying factors driving persistent violence-related injuries during shelter-in-place orders should be a focus of public health efforts in preparation for future pandemic responses. LEVEL OF EVIDENCE:Epidemiological study, level III.

IMPORTANCE:The term prediabetes is used to identify individuals at increased risk for diabetes. However, the natural history of prediabetes in older age is not well characterized. OBJECTIVES:To compare different prediabetes definitions and characterize the risks of prediabetes and diabetes among older adults in a community-based setting. DESIGN, SETTING, AND PARTICIPANTS:In this prospective cohort analysis of 3412 older adults without diabetes from the Atherosclerosis Risk in Communities Study (baseline, 2011-2013), participants were contacted semiannually through December 31, 2017, and attended a follow-up visit between January 1, 2016, and December 31, 2017 (median [range] follow-up, 5.0 [0.1-6.5] years). EXPOSURES:Prediabetes defined by a glycated hemoglobin (HbA1c) level of 5.7% to 6.4%, impaired fasting glucose (IFG) level (FG level of 100-125 mg/dL), either, or both. MAIN OUTCOMES AND MEASURES:Incident total diabetes (physician diagnosis, glucose-lowering medication use, HbA1c level ≥6.5%, or FG level ≥126 mg/dL). RESULTS:A total of 3412 participants without diabetes (mean [SD] age, 75.6 [5.2] years; 2040 [60%] female; and 572 [17%] Black) attended visit 5 (2011-2013, baseline). Of the 3412 participants at baseline, a total of 2497 participants attended the follow-up visit or died. During the 6.5-year follow-up period, there were 156 incident total diabetes cases (118 diagnosed) and 434 deaths. A total of 1490 participants (44%) had HbA1c levels of 5.7% to 6.4%, 1996 (59%) had IFG, 2482 (73%) met the HbA1c or IFG criteria, and 1004 (29%) met both the HbA1c and IFG criteria. Among participants with HbA1c levels of 5.7% to 6.4% at baseline, 97 (9%) progressed to diabetes, 148 (13%) regressed to normoglycemia (HbA1c, <5.7%), and 207 (19%) died. Of those with IFG at baseline, 112 (8%) progressed to diabetes, 647 (44%) regressed to normoglycemia (FG, <100 mg/dL), and 236 (16%) died. Of those with baseline HbA1c levels less than 5.7%, 239 (17%) progressed to HbA1c levels of 5.7% to 6.4% and 41 (3%) developed diabetes. Of those with baseline FG levels less than 100 mg/dL, 80 (8%) progressed to IFG (FG, 100-125 mg/dL) and 26 (3%) developed diabetes. CONCLUSIONS AND RELEVANCE:In this community-based cohort study of older adults, the prevalence of prediabetes was high; however, during the study period, regression to normoglycemia or death was more frequent than progression to diabetes. These findings suggest that prediabetes may not be a robust diagnostic entity in older age.

BACKGROUND:Mounting evidence suggests disproportionate coronavirus disease 2019 (COVID-19) hospitalizations and deaths because of racial disparities. The association of race in a cohort of gynecologic oncology patients with severe acute respiratory syndrome-coronavirus 2 infection is unknown. METHODS:Data were abstracted from gynecologic oncology patients with COVID-19 infection among 8 New York City area hospital systems. A multivariable mixed-effects logistic regression model accounting for county clustering was used to analyze COVID-19-related hospitalization and mortality. RESULTS:Of 193 patients who had gynecologic cancer and COVID-19, 67 (34.7%) were Black, and 126 (65.3%) were non-Black. Black patients were more likely to require hospitalization compared with non-Black patients (71.6% [48 of 67] vs 46.0% [58 of 126]; P = .001). Of 34 (17.6%) patients who died from COVID-19, 14 (41.2%) were Black. Among those who were hospitalized, compared with non-Black patients, Black patients were more likely to: have ≥3 comorbidities (81.1% [30 of 37] vs 59.2% [29 of 49]; P = .05), to reside in Brooklyn (81.0% [17 of 21] vs 44.4% [12 of 27]; P = .02), to live with family (69.4% [25 of 36] vs 41.6% [37 of 89]; P = .009), and to have public insurance (79.6% [39 of 49] vs 53.4% [39 of 73]; P = .006). In multivariable analysis, among patients aged <65 years, Black patients were more likely to require hospitalization compared with non-Black patients (odds ratio, 4.87; 95% CI, 1.82-12.99; P = .002). CONCLUSIONS:Although Black patients represented only one-third of patients with gynecologic cancer, they accounted for disproportionate rates of hospitalization (>45%) and death (>40%) because of COVID-19 infection; younger Black patients had a nearly 5-fold greater risk of hospitalization. Efforts to understand and improve these disparities in COVID-19 outcomes among Black patients are critical.

OBJECTIVE:Familial Dysautonomia (FD) disease, lacks a useful biomarker for clinical monitoring. In this longitudinal study we characterized the structural changes in the macula, peripapillary and the optic nerve head (ONH) regions in subjects with FD. METHODS:Data was consecutively collected from subjects attending the FD clinic between 2012 and 2019. All subjects were imaged with spectral-domain Optical Coherence Tomography (OCT). Global and sectoral measurements of mean retinal nerve fiber layer (RNFL) and macular ganglion cell and inner plexiform layer (GCIPL) thickness, and ONH parameters of rim area, average cup-to-disc (C:D) ratio, and cup volume were used for the analysis. The best fit models (linear, quadratic and broken stick linear model) were used to describe the longitudinal change in each of the parameters. RESULTS:91 subjects (149 eyes) with FD of ages 5-56 years were included in the analysis. The rate of change for average RNFL and average GCIPL thicknesses were significant before reaching a plateau at the age of 26.2 for RNFL and 24.8 for GCIPL (- 0.861 µm/year (95% CI - 1.026, - 0.693) and - 0.553 µm/year (95% CI - 0.645, - 0.461), respectively). Significant linear rate of progression was noted for all ONH parameters, except for a subset of subjects (24%), with no cupping that did not show progression in any of the ONH parameters. CONCLUSIONS:The rapidly declining RNFL and GCIPL can explain the progressive visual impairment previously reported in these subjects. Among all structural parameters, ONH parameters might be most suitable for longitudinal follow-up, in eyes with a measurable cup.

Background: Modifiable risk factors contribute to not only the development, but also the progression of dementia. Smoking is a relevant risk factor, and although relatively few people with dementia are smokers, smoking cessation can positively impact both patient quality of life and healthcare system costs. Notably, these patients also have an increased risk of smoking-related accidents and fire hazards. Despite this, smoking cessation is not routinely addressed in dementia care, and there are no reported smoking cessation interventions specifically for dementia patients. Therefore, we are developing and pilot testing an approach to help smokers with cognitive impairment quit smoking.
Method(s): We are conducting a study of financial incentives to increase smoking cessation among patients hospitalized at 2 public safety net hospitals. We received an NIA supplement to include cognitively impaired patients, who were originally excluded from the study. We will begin by investigating how to adapt smoking cessation interventions for patients with cognitive impairment by conducting structured interviews with 15 current smokers, who have a diagnosis of cognitive impairment or dementia, and their caregivers. Based on analysis of interview transcripts, we will adapt both the intervention arms and our smoking cessation counseling manuals. We will then test these modifications on 6 patients with cognitive impairment and adapt them further. For the FIESTA II pilot study, we will recruit 50 participants, who will be randomized to standard therapy or one of the two financial incentive arms. Standard therapy includes the use of NRT, medication, and individual counseling targeting smoking cessation. The two financial incentive arms will be either outcome-based or goalbased, where patients are compensated for successful smoking abstinence or utilization of counseling and quitting aids, respectively. Our outcomes for the pilot study are use of smoking cessation treatments, quit attempts and abstinence.
Result(s): We are currently conducting the initial qualitative interviews.
Conclusion(s): We will discuss the results of the pilot study and their implications for geriatric practice

BACKGROUND:Buprenorphine treatment remains unavailable in many jails and prisons, but use of nonprescribed (i.e., diverted) buprenorphine has been reported in these settings. The purpose of this analysis is to explore the experiences and motivations behind the use of diverted buprenorphine among recently incarcerated individuals. METHODS:Adults with opioid misuse who were recently released from jail or prison (n= 26; 58% male) completed semi-structured qualitative interviews as part of a study focused on buprenorphine diversion in the criminal justice system. Qualitative interviews explored participants' incarceration experiences and opioid use background, knowledge of buprenorphine and other substance use in jails/prisons, personal use of buprenorphine while incarcerated, reasons for using buprenorphine while incarcerated, and knowledge of how buprenorphine is brought into and acquired in jails/prisons. The study recorded and transcribed interviews, and analyzed the narratives for content related to these predetermined thematic areas. RESULTS:Key themes emerging from the interviews surrounding buprenorphine diversion during incarceration included: 1) the perceived high prevalence of diverted buprenorphine in jail/prison settings, 2) how the perception of prevalence is related to buprenorphine sublingual film formulation, 3) adaptive routes of administration related to the high cost of diverted buprenorphine, and 4) reasons individuals who are incarcerated use diverted buprenorphine (to achieve euphoric effects and cope with confinement, in contrast to using for self-treatment/withdrawal management as is done in the community). CONCLUSION/CONCLUSIONS:Participants reported widespread availability of diverted buprenorphine in criminal justice facilities, and characterized reasons for its use specific to these contexts. More research is needed to determine the impact of expanding buprenorphine treatment in jails and prisons on inmates' use of diverted buprenorphine, and future research should explore these intersections as treatment initiation opportunities.
