BACKGROUND:The United Arab Emirates (UAE) is faced with a rapidly increasing burden of non-communicable diseases including obesity, diabetes, and cardiovascular disease. The UAE Healthy Future study is a prospective cohort designed to identify associations between risk factors and these diseases amongst Emiratis. The study will enroll 20,000 UAE nationals aged ≥18 years. Environmental and genetic risk factors will be characterized and participants will be followed for future disease events. As this was the first time a prospective cohort study was being planned in the UAE, a pilot study was conducted in 2015 with the primary aim of establishing the feasibility of conducting the study. Other objectives were to evaluate the implementation of the main study protocols, and to build adequate capacity to conduct advanced clinical laboratory analyses. METHODS:Seven hundred sixty nine UAE nationals aged ≥18 years were invited to participate voluntarily in the pilot study. Participants signed an informed consent, completed a detailed questionnaire, provided random blood, urine, and mouthwash samples and were assessed for a series of clinical measures. All specimens were transported to the New York University Abu Dhabi laboratories where samples were processed and analyzed for routine chemistry and hematology. Plasma, serum, and a small whole blood sample for DNA extraction were aliquoted and stored at -80 °C for future analyses. RESULTS:Overall, 517 Emirati men and women agreed to participate (68% response rate). Of the total participants, 495 (95.0%), 430 (82.2%), and 492 (94.4%), completed the questionnaire, physical measurements, and provided biological samples, respectively. CONCLUSIONS:The pilot study demonstrated the feasibility of recruitment and completion of the study protocols for the first large-scale cohort study designed to identify emerging risk factors for the major non-communicable diseases in the region.

Introduction: Veterans with mental health disorders smoke at high rates, but encounter low rates of tobacco treatment. We sought to understand barriers and facilitators to treating tobacco use in VA mental health clinics. Methods: This qualitative study was part of a trial evaluating a telephone care coordination program for smokers using mental health services at 6 VA facilities. We conducted semi-structured interviews with 14 staff: 12 mental health clinic staff working at the parent study's intervention sites (n=6 psychiatrists, 3 psychologists, 2 social workers, 1 NP), as well as one psychiatrist and one psychologist on the VA's national tobacco advisory committee. Interviews were transcribed and inductively coded to identify themes. Results: Five "barriers" themes emerged: 1) competing priorities, 2) patient challenges/resistance, 3) complex staffing/challenging cross-discipline coordination, 4) mixed perceptions about whether tobacco is a mental health care responsibility, and 5) limited staff training/comfort in treating tobacco. Five "facilitators" themes emerged: 1) reminding mental health staff about tobacco, 2) staff belief in the importance of addressing tobacco, 3) designating a cessation medication prescriber, 4) linking tobacco to mental health outcomes and norms, and 5) limiting mental health staff burden. Conclusions: VA mental health staff struggle with knowing that tobacco use is important, but they face competing priorities, encounter patient resistance, are conflicted on their role in addressing tobacco, and lack tobacco training. They suggested strategies at multiple levels that would help overcome those barriers that can be used to design interventions that improve tobacco treatment delivery for mental health patients. IMPLICATIONS: This study builds upon the existing literature on the high rates of smoking, but low rates of treatment, in people with mental health diagnoses. This study is one of the few qualitative evaluations of mental health clinic staff perceptions of barriers and facilitators to treating tobacco. The study results provide a multi-level framework for developing strategies to improve the implementation of tobacco treatment programs in mental health clinics.

BACKGROUND: The Veterans Health Administration (VA) is investing considerable resources into providing remote management care to patients for disease prevention and management. Remote management includes online patient portals, e-mails between patients and providers, follow-up phone calls, and home health devices to monitor health status. However, little is known about patients' attitudes and preferences for this type of care. This qualitative study was conducted to better understand patient preferences for receiving remote care. METHODS: Ten focus groups were held comprising 77 patients with hypertension or tobacco use history at two VA medical centers. Discussion questions focused on experience with current VA remote management efforts and preferences for receiving additional care between outpatient visits. RESULTS: Most participants were receptive to remote management for referrals, appointment reminders, resource information, and motivational and emotional support between visits, but described challenges with some technological tools. Participants reported that remote management should be personalized and tailored to individual needs. They expressed preferences for frequency, scope, continuity of provider, and mode of communication between visits. Most participants were open to nonclinicians contacting them as long as they had direct connection to their medical team. Some participants expressed a preference for a licensed medical professional. All groups raised concerns around confidentiality and privacy of healthcare information. Female Veterans expressed a desire for gender-sensitive care and an interest in complementary and alternative medicine. CONCLUSIONS: The findings and specific recommendations from this study can improve existing remote management programs and inform the design of future efforts.

INTRODUCTION: Individuals with (vs. without) mental illness use tobacco at higher rates and have more difficulty quitting. Treatment models for smokers with mental illness are needed. METHODS: This secondary analysis of the Victory Over Tobacco study [a pragmatic randomized clinical trial (N=5123) conducted in 2009-2011 of Proactive Care (proactive outreach plus connection to smoking cessation services) vs. Usual Care] tests the effectiveness of treatment assignment in participants with and without a mental health diagnosis on population-level, 6month prolonged abstinence at one year follow-up. RESULTS: Analyses conducted in 2015-6 found that there was no interaction between treatment group and mental health group on abstinence (F(1,3300=1.12, p=0.29)). Analyses stratified by mental health group showed that those without mental illness, assigned to Proactive Care, had a significantly higher population-level abstinence rate than those assigned to Usual Care (OR=1.40, 95% CI=1.17-1.67); in those with mental illness, assignment to Proactive Care produced a non-significant increase in abstinence compared to Usual Care (OR=1.18, 95% CI=0.98-1.41). Those with mental illness reported more medical visits, cessation advice and treatment (p<0.001), similar levels of abstinence motivation (p>0.05), but lower abstinence self-efficacy (p<0.001). CONCLUSIONS: Those with a mental health diagnosis benefitted less from proactive outreach regarding tobacco use. VA primary care patients with mental illness may not need additional outreach because they are connected to cessation resources during medical appointments. This group may also require more intensive cessation interventions targeting self-efficacy to improve cessation rates. Clinicaltrials.gov registration # NCT00608426.

OBJECTIVES: Despite previous retrospective reports that the number of lymph nodes resected at curative intent surgery for lung cancer correlates with overall survival (OS), no consensus exists regarding the minimal nor optimal number of lymph nodes to resect at curative lung cancer surgery. METHODS: We studied subjects in the Surveillance Epidemiology and End Results Database (SEER) diagnosed with non-small cell lung cancer between 2000 and 2011 who underwent either lobectomy or pneumonectomy and had pathologic negative nodal evaluation. We excluded patients with sublobar resection and/or no lymph node evaluation. We examined associations between number of lymph nodes evaluated and OS/lung cancer-specific survival by multivariable Cox regression; and predictors of evaluation of more lymph nodes. RESULTS: Among the 33,463 patients in our sample, a median of 7 lymph nodes were evaluated. We found that lung cancer-specific survival and OS improved with increasing lymph node evaluation up to 16 to 18 lymph nodes (hazard ratio, 0.77 [95% confidence interval, 0.70-0.85] and 0.78 [95% confidence interval, 0.72-0.86], respectively). There was little additional improvement in outcomes with evaluation of >16 to 18 lymph nodes. Blacks, Hispanics, females, and patients from distinct geographical regions were less likely to have 16 or more lymph nodes evaluated. CONCLUSIONS: There was a consistently increasing survival benefit associated with a more extensive lymph node evaluation at lung cancer resection, up to 16 to 18 lymph nodes removed. The median number of nodes evaluated was, however, only 7, suggesting that setting a goal of >/=16 examined lymph nodes may lead to improved survival outcomes, and reduce disparities in care.

OBJECTIVES: We conducted two parallel studies evaluating the effectiveness of proactive and reactive engagement approaches to telephone treatment for smoking cessation. METHODS: Patients who smoked and were interested in quitting were referred to this study and were eligible if they were current smokers and had an address and a telephone number. The data were collected at 35 Department of Veterans Affairs (VA) sites, part of four VA medical centres in both California and Nevada. In study 1, participants received multisession counselling from the California Smokers' Helpline (quitline). In study 2, they received self-help materials only. Patients were randomly assigned by week to either proactive or reactive engagement, and primary care staff were blind to this assignment. Providers gave brief advice and referred them via the electronic health record to a tobacco co-ordinator. All patients were offered cessation medications. OUTCOME: Using complete case analysis, in study 1 (quitline), patients in the proactive condition were more likely than those in the reactive condition to report abstinence at 6 months (21.0% vs 16.4%, p=0.03). No difference was found between conditions in study 2 (self-help) (16.9% vs 16.5%, p=0.88). Proactive outreach resulted in increased use of cessation medications in both the quitline (70.1% vs 57.6%, p<0.0001) and the self-help studies (74.5% vs 48.2%, p<0.0001). CONCLUSION: Proactive outreach with quitline intervention was associated with greater long-term abstinence. Both studies resulted in high rates of medication use. Sites should use a proactive outreach approach and provide counselling whenever possible. TRIAL REGISTRATION NUMBER: NCT00123682.

Persons with mental health diagnoses use tobacco at alarming rates, yet misperceptions remain about the effect of quitting on mental health outcomes. This article examines the relationship between tobacco cessation and changes in severity of mental illness. Participants were N = 577 veterans with a history of mental health treatment enrolled in a tobacco cessation study. The effects of abstinence and time on Behavior and Symptom Identification Scale-24 summary scores and subscales were examined. Abstinence at both 2 and 6 months post-baseline was related (p < .0001) to lower Behavior and Symptom Identification Scale-24 summary scores and improvement on three Behavior and Symptom Identification Scale-24 subscales. Providers should recommend and provide tobacco treatment to all mental health patients to improve their physical and mental health functioning.

Significance: Limited data exist regarding tobacco and nicotine containing product (TNCP) use and their association with other drugs of abuse in high-risk settings. The purpose of this study was to examine the associations between TNCP use and other common illicit drug use among adults attending Electronic Dance Music (EDM) parties at nightclubs and festivals in New York City (NYC).
Method(s): Adults (age 18-40) were recruited outside of EDM events in NYC between May and August 2016 and completed a computer-assisted personal interview on a tablet. The survey took approximately 10 minutes and queried sociodemographic characteristics, and self-reported use of TNCPs (e-cigarettes, hookah, and "tobacco") and other drugs. Among recent (12-month) TNCP users, we compared illicit drug use according to the number of TNCPs reportedly used with the use of 1 TNCP representing mono-use, any 2 representing dual-use, and all 3 representing poly-use.
Result(s): More than half the overall sample (54%; N = 524 of 965) reported past year use of a TNCP. Participants' mean age was (25.1+4.5) years, and 55.2% were male. Almost half (46%) were mono users, 27% were dual TNCP users, and 27% were poly TNCP users. Sociodemographic characteristics were not associated with a number of TNCPs used; however, a number of products was significantly different regarding the past-year use of marijuana, powder cocaine, ecstasy (MDMA, "Molly"), LSD, and psilocybin ("magic mushrooms"). Poly users were more likely to report use of marijuana (94.4% vs 87.9% dual and 68.3% mono; P < 0.001), cocaine (69.2% vs 56.7% dual and 32.1% mono; P < 0.001), ecstasy (65.0% vs 61.0% dual and 49.6% mono; P = 0.007), LSD (46.9% vs 34.8% dual and 19.6% mono; P< 0.001), and psilocybin (44.8% vs 31.2% dual and 16.7% mono; P< 0.001).
Conclusion(s): Among this sample of EDM attendees in NYC, past-year use of TNCPs was strongly associated with the use of illicit drugs suggesting the use of more TNCPs is associated with risky behavior in high-risk settings. A limitation was that "tobacco" included all other TNCPs other than e-cigarettes and hookah. Adults' TNCP use patterns might be indicative of the extent of illicit drug use, especially among those frequenting high-risk settings. Future research needs to probe in the reasons behind the patterns of TNCP use among those in high-risk settings

Medical-legal partnerships-collaborations between legal professionals and health care providers that help patients address civil legal problems that can affect health and well-being-have been implemented at several Veterans Affairs (VA) medical centers to serve homeless and low-income veterans with mental illness. We describe the outcomes of veterans who accessed legal services at four partnership sites in Connecticut and New York in the period 2014-16. The partnerships served 950 veterans, who collectively had 1,384 legal issues; on average, the issues took 5.4 hours' worth of legal services to resolve. The most common problems were related to VA benefits, housing, family issues, and consumer issues. Among a subsample of 148 veterans who were followed for one year, we observed significant improvements in housing, income, and mental health. Veterans who received more partnership services showed greater improvements in housing and mental health than those who received fewer services, and those who achieved their predefined legal goals showed greater improvements in housing status and community integration than those who did not. Medical-legal partnerships represent an opportunity to expand cross-sector, community-based partnerships in the VA health care system to address social determinants of mental health.
