The World Trade Center attacks of 11 September 2001 (9/11) have been associated with the subsequent development of chronic diseases. Few studies have investigated the burden of somatic symptoms on attack victims, or the association of such symptoms with exposure to the 9/11 attacks. World Trade Center Health Registry (Registry) enrollees who were present south of Chambers Street during or immediately after the 9/11 attacks and who provided consistent answers regarding injury sustained on 9/11 were followed prospectively for up to 16 years post-9/11/01. We employed linear regression to evaluate the associations between injury severity, psychological distress and somatic symptoms in 2322 persons who completed all four Registry surveys and a subsequent Health and Quality of Life survey. Twenty-one percent of subjects had a "very high" burden of somatic symptoms, greater than in populations not exposed to a disaster. Somatic symptoms exhibited a dose-response association separately with injury severity and psychological distress trajectories. Victims of the 9/11 attacks suffer from a substantial burden of somatic symptoms which are associated with physical and psychological consequences of exposure to the attacks. Physical and mental health professionals need to work together when treating those exposed to complex disasters such as 9/11.

INTRODUCTION/BACKGROUND:Parents are essential stakeholders for policy implementation. However, data on parents' support for e-cigarette- and tobacco-related policies is limited. This study examines parents' support for five e-cigarette- and tobacco-related policies targeted to prevent youth initiation and exposure to industry marketing practices. METHODS:Data were from a 2018 nationally representative sample of US parents of 11-18-year-old middle and high school students. Weighted adjusted logistic regression models examined correlates of support for policy outcomes, controlling for demographics. Analyses were performed among the full sample (n=2,743) and among current tobacco users (n=355). RESULTS:The majority of parents, including current tobacco users, supported tobacco control efforts to protect adolescents. Over 90% of all parents supported restrictions on e-cigarette marketing to youth and 75% supported a ban on flavored e-cigarette sales. Additionally, over 80% of all parents supported increasing the age of tobacco product sale to 21, limiting tobacco retailer density near schools, and keeping tobacco products out of view where youth shop. Presence of strict home tobacco rules or reporting a high priority to prevent child's e-cigarette use were significantly associated with higher odds of policy support. Results were similar among current tobacco users. CONCLUSIONS:Parents are an important group of tobacco control stakeholders and should be utilized to garner support for tobacco control policies in the context of the recent growth in youth tobacco and e-cigarette use. Parents' public support for tobacco control policies, particularly regulations on e-cigarette sales and marketing, can motivate advocates and policymakers to advance tobacco control policy agendas.

INTRODUCTION/BACKGROUND:Smoking is a key determinant of mortality among people living with HIV (PLWH). METHODS:To better understand the effects of smoking cessation interventions in PLWH, we conducted a pooled analysis of four randomized controlled trials of hospital-initiated smoking interventions conducted through the Consortium of Hospitals Advancing Research on Tobacco (CHART). In each study, cigarette smokers were randomly assigned to usual care or a smoking cessation intervention. The primary outcome was self-reported past 30-day tobacco abstinence at 6-month follow-up. Abstinence rates were compared between PLWH and participants without HIV and by treatment arm, using both complete-case and intention-to-treat analyses. Multivariable logistic regression was used to determine the effect of HIV status on 6-month tobacco abstinence and to determine predictors of smoking cessation within PLWH. RESULTS:Among 5550 hospitalized smokers, there were 202 (3.6%) PLWH. PLWH smoked fewer cigarettes per day and were less likely to be planning to quit than smokers without HIV. At 6 months, cessation rates did not differ between intervention and control groups among PLWH (28.9% vs. 30.5%) or smokers without HIV (36.1% vs. 34.1%). In multivariable regression analysis, HIV status was not significantly associated with smoking cessation at 6 months. Among PLWH, confidence in quitting was the only clinical factor independently associated with smoking cessation (OR 2.0, 95% CI = 1.4 to 2.8, p < .01). CONCLUSIONS:HIV status did not alter likelihood of quitting smoking after hospital discharge, whether or not the smoker was offered a tobacco cessation intervention, but power was limited to identify potentially important differences. IMPLICATIONS/CONCLUSIONS:PLWH had similar quit rates to participants without HIV following a hospital-initiated smoking cessation intervention. The findings suggest that factors specific to HIV infection may not influence response to smoking cessation interventions and that all PLWH would benefit from efforts to assist in quitting smoking.

NYC Health + Hospitals (NYC H+H) is the largest safety net health care delivery system in the United States. Prior to the novel coronavirus disease (COVID-19) pandemic, NYC H+H served over one million patients, including the most vulnerable New Yorkers, and billed fewer than 500 telehealth visits monthly. Once the pandemic struck, we established a strategy to allow us to continue to serve existing patients and treat the surge of new patients. Starting in March 2020 we were able to transform the system using virtual care platforms through which we conducted almost 83,000 billable televisits in one month and more than 30,000 behavioral health encounters via telephone and video. Telehealth also enabled us to support patient-family communication, post-discharge follow-up, and palliative care for COVID-19 patients. Expanded Medicaid coverage and insurance reimbursement for telehealth played a pivotal role in this transformation. As we move to a new blend of virtual and in-person care, it is vital that the major regulatory and insurance changes undergirding our COVID-19 telehealth response be sustained to protect access for our most vulnerable patients.

Sialic acids are terminal sugars on the cell surface that are found on all cell types including immune cells like natural killer (NK) cells. The attachment of sialic acids to different glycan structures is catalyzed by sialyltransferases in the Golgi. However, the expression pattern of sialyltransferases in NK cells and their expression after activation has not yet been analyzed. Therefore, the present study determines which sialyltransferases are expressed in human NK cells and if activation with IL-2 changes the sialylation of NK cells. The expression of sialyltransferases was analyzed in the three human NK cell lines NK-92, NKL, KHYG-1 and primary NK cells. NK-92 cells were cultured in the absence or presence of IL-2, and changes in the sialyltransferase expression were measured by qPCR. Furthermore, specific sialylation was investigated by flow cytometry. In addition, polySia and NCAM were measured by Western blot analyses. IL-2 leads to a reduced expression of ST8SIA1, ST6GAL1 and ST3GAL1. α-2,3-Sialylation remained unchanged, while α-2,6-sialylation was increased after IL-2 stimulation. Moreover, an increase in the amount of NCAM and polySia was observed in IL-2-activated NK cells, whereas GD3 ganglioside was decreased. In this study, all sialyltransferases that were expressed in NK cells could be identified. IL-2 regulates the expression of some sialyltransferases and leads to changes in the sialylation of NK cells.

Ascending to the peak of the novel coronavirus disease (COVID-19) pandemic in New York City, NYC Health + Hospitals (NYC H+H), the City's public health care system, rapidly expanded capacity across its 11 acute-care hospitals and three new field hospitals. To meet the unprecedented demand for patient care, NYC H+H redeployed staff to the areas of greatest need and redesigned recruiting, onboarding, and training processes. The hospital system engaged private staffing agencies, partnered with the U.S Department of Defense, and recruited volunteers throughout the country. A centralized onboarding team created a single-source portal for medical providers requiring credentialing and established new staff positions to increase efficiency. Using new educational tools focused on COVID-19 content, the hospital system trained 20,000 staff, including nearly 9,000 nurses, within a two-month period. Creation of multidisciplinary teams, frequent enterprise-wide communication, willingness to shift direction in response to changing needs, and innovative use of technology were the key factors that enabled the hospital system to meet its goals.

IMPORTANCE/OBJECTIVE:New York City is a global epicenter for the SARS-CoV-2 outbreak with a significant number of individuals infected by the virus. Patients with multiple myeloma have a compromised immune system, due to both the disease and anti-myeloma therapies, and may therefore be particularly susceptible to coronavirus disease 2019 (COVID-19); however, there is limited information to guide clinical management. OBJECTIVE:To assess risk factors and outcomes of COVID-19 in patients with multiple myeloma. DESIGN/METHODS:Case-series. SETTING/METHODS:Five large academic centers in New York City. PARTICIPANTS/METHODS:Patients with multiple myeloma and related plasma cell disorders who were diagnosed with COVID-19 between March 10th, 2020 and April 30th, 2020. Exposures: Clinical features and risk factors were analyzed in relation to severity of COVID-19. Main Outcomes and Measures: Descriptive statistics as well as logistic regression were used to estimate disease severity reflected in hospital admissions, intensive care unit (ICU) admission, need for mechanical ventilation, or death. RESULTS:Of 100 multiple myeloma patients (male 58%; median age 68, range 41-91) diagnosed with COVID-19, 74 (74%) were admitted; of these 13 (18%) patients were placed on mechanical ventilation, and 18 patients (24%) expired. None of the studied risk factors were significantly associated (P>0.05) with adverse outcomes (ICU-admission, mechanical ventilation, or death): hypertension (N=56) odds ratio (OR) 2.3 (95% confidence interval [CI] 0.9-5.9); diabetes (N=18) OR 1.1 (95% CI 0.3-3.2); age >65 years (N=63) OR 2.0 (95% CI 0.8-5.3); high dose melphalan with autologous stem cell transplant <12 months (N=7) OR 1.2 (95% CI 0.2-7.4), IgG<650 mg/dL (N=42) OR=1.2 (95% CI 0.4-3.1). In the entire series of 127 patients with plasma cell disorders, hypertension was significantly associated with the combined end-point (OR 3.4, 95% CI 1.5-8.1). CONCLUSIONS AND RELEVANCE/CONCLUSIONS:Although multiple myeloma patients have a compromised immune system due to both the disease and therapy; in this largest disease specific cohort to date of patients with multiple myeloma and COVID-19, compared to the general population, we found risk factors for adverse outcome to be shared and mortality rates to be within the higher range of officially reported mortality rates.

New York City (NYC) has emerged as the global epicenter for the COVID-19 pandemic. The NYC Public Health System (NYC Health +Hospitals, NYC H + H) was key to the city's response because its vulnerable patient population was disproportionately affected by the disease. As cases rose in the city, NYC H+H carried out plans to greatly expand critical care capacity. Primary ICU spaces were identified and upgraded as needed, while new ICU spaces were created in emergency departments (EDs), procedural areas, and other inpatient units. Patients were transferred between hospitals in order to reduce strain. Critical care staffing was supplemented by temporary recruits, volunteers, and military deployments. Supplies to deliver critical care were monitored closely and obtained as needed to prevent interruptions. An ED action team was formed to ensure that the experience of frontline providers was informing network level decisions. The steps taken by NYC H+H greatly expanded its capacity to provide critical care during an unprecedented surge of COVID-19 cases in NYC. These steps, along with lessons learned, could inform preparations for other health systems during a primary or secondary surge of cases.

Understanding how previous experiences with interprofessional education and collaboration inform health care provider perspectives is important for developing interprofessional interventions at the graduate level. The purpose of this study was to examine how previous work experiences of graduate level health professions students inform perspectives about interprofessional education and collaboration. Drawing from program evaluation data of two separate graduate level interprofessional education interventions based in primary care and home health care, we conducted a qualitative secondary data analysis of 75 interviews generated by focus groups and individual interviews with graduate students from 4 health professions cadres. Using directed content analysis, the team coded to capture descriptions of interprofessional education or collaboration generated from participants' previous work experiences. Coding revealed 173 discrete descriptions related to previous experiences of interprofessional education or collaboration. Three themes were identified from the analysis that informed participant perspectives: Previous educational experiences (including work-based training); previous work experiences; and organizational factors and interprofessional collaboration. Experiences varied little between professions except when aspects of professional training created unique circumstances. The study reveals important differences between graduate and undergraduate learners in health professions programs that can inform interprofessional education and collaboration intervention design.

OBJECTIVES/OBJECTIVE:This study assessed how few community-based programs target older people living with HIV. METHODS:We conducted four focus groups comprised of people 50 and older with HIV (N = 32; gay/bisexual men, heterosexual men, women, and Spanish-speakers) to inform HIV program development by exploring the services in which participants were actively involved, along with the services they wanted to receive. RESULTS:Using inductive thematic qualitative analysis, four themes were identified pertaining to program development: (a) types of currently utilized HIV service organizations; (b) dissatisfaction with HIV programming and services; (c) participants' preferred programming, courses, groups, or activities; and (d) desire to serve as peer mentors. CONCLUSIONS:Results highlight the need for community-based organizations to address social engagement and isolation among older people living with HIV. CLINICAL IMPLICATIONS/CONCLUSIONS:These findings exemplify the need for programs to be specifically designed for OPH, and created with the primary goals of socialization and helping develop social support networks.
