Abstract Background: Assessment of nicotine metabolism and disposition has become an integral part of nicotine dependency treatment programs. Serum nicotine concentrations or urine cotinine concentrations can be used to guide nicotine patch dose to achieve biological concentrations adequate to provide the patient with immediate relief from nicotine withdrawal symptoms, an important factor in nicotine withdrawal success. Absence of nicotine metabolites and anabasine can be used to document abstinence from tobacco products, an indicator of treatment success. Methods: The procedure was designed to quantify nicotine, cotinine, trans-3′-hydroxycotinine, anabasine, and nornicotine in human serum or urine. The technique required simple extraction of the sample with quantification by HPLC–tandem mass spectrometry. Results: The procedure for simultaneous analysis of nicotine, its metabolites, and tobacco alkaloids simultaneously quantified five different analytes. Test limit of quantification, linearity, imprecision, and accuracy were adequate for clinical evaluation of patients undergoing treatment for tobacco dependency. The test readily distinguished individuals who had no exposure to tobacco products from individuals who were either passively exposed or were abstinent past-tobacco users from those who were actively using a tobacco or nicotine product. Conclusions: Nicotine, cotinine, trans-3′-hydroxycotinine, nornicotine, and anabasine can be simultaneously and accurately quantified in either serum or urine by HPLC–tandem mass spectrometry with imprecision <10% at physiologic concentrations and limits of quantification ranging from 0.5 to 5 μg/L. Knowledge of serum or urine concentrations of these analytes can be used to guide nicotine replacement therapy or to assess tobacco abstinence in nicotine dependency treatment. These measurements are now an integral part of the clinical treatment and management of patients who wish to overcome tobacco dependence.

Abstract Background Infectious diseases (ID) consultation is associated with improved outcomes for patients hospitalized with infection. Provision of this service is not practical for many smaller hospitals, particularly critical access facilities. We sought to evaluate the impact of an electronic, asynchronous consultative service (“eConsults”) at two rural hospitals without on-site ID support. Methods Beginning July 2018, ID physicians at Mayo Clinic, Rochester, began performing asynchronous eConsults for patients hospitalized at Mayo Clinic Health System (MCHS) Albert Lea and MCHS Austin Hospitals. The first 100 consecutive patients receiving eConsults (cases) were compared with patients admitted for infection at the same facilities prior to pilot initiation (controls). Cases were matched to controls using 1:3 propensity match based on age, gender, race, and weighted Charlson comorbidity index. The primary outcome was readmission or death within 30 days after hospital discharge. Results Cases (n = 100) were more likely to have been hospitalized in the 6 months prior to the index hospitalization than controls (n = 300) (P < 0.0001). Patients with ID eConsult had a significantly decreased odds of death at 30 days (OR 0.3, 95% CI 0.2–0.7, P = 0.003) and there was a trend toward decreased readmission at 30 days (OR 0.4, 95% CI 0.2–1.1, P = 0.07). The mean length of stay was significantly longer for cases (5.7 days vs. 3.8 days, P =0.003). However, ID eConsult did not occur until 2.6 days into hospitalization, on average. Conclusion ID eConsultation was associated with lower odds of 30-day mortality. The increased length of stay may be mitigated by encouraging ID eConsults earlier during hospitalization. Inpatient ID eConsults represent a high-value proposition for patients and providers and a feasible means of expanding the reach of ID physicians. This novel care delivery model warrants further investigations. Disclosures All authors: No reported disclosures.

Objective: Much has been written about the patients’ perspective concerning weight management in health care. The purpose of this survey study was to assess perspectives of primary care providers (PCPs) and nurses toward patient weight management and identify possible areas of growth. Patients and Methods: We emailed a weight management–focused survey to 674 eligible participants (437 [64.8%] nurses and 237 [35.2%] PCPs) located in 5 outpatient primary care clinics. The survey focused on opportunities, practices, knowledge, confidence, attitudes, and beliefs. A total of 219 surveys were returned (137 [62.6%] from nurses and 82 [34.4%] from PCPs). Results: Among 219 responders, 85.8% were female and 93.6% were white non-Hispanic. In this study, PCPs and nurses believed obesity to be a major health problem. While PCPs felt more equipped than nurses to address weight management ( P < .001) and reported receiving more training than nurses (50.0% vs 17.6%, respectively), both felt the need for more training on obesity (73.8% and 79.4%, respectively). Although, PCPs also spent more patient contact time providing weight management services versus nurses ( P < .001), the opportunity/practices score was lower for PCPs than nurses (−0.35 ± 0.44 vs −0.17 ± 0.41, P < .001) with PCPs more likely to say they lacked the time to discuss weight and they worried it would cause a poor patient-PCP relationship. The knowledge/confidence score also differed significantly between the groups, with nurses feeling less equipped to deal with weight management issues than PCPs (−0.42 ± 0.43 vs −0.03 ± 0.55, P < .001). Neither group seemed very confident, with those in the PCP group only answering with an average score of neutral. Conclusion: By asking nurses and PCP general questions about experiences, attitudes, knowledge, and opinions concerning weight management in clinical care, this survey has identified areas for growth in obesity management. Both PCPs and nurses would benefit from additional educational training on weight management.

Objective: Chronic daily pain is experienced by 11.2% of United States adults and psychosocial factors have significant impact on self-reported pain. Most research in this area has focused on pain-related conditions, not the general population. This study sought to understand the associations between clinically significant chronic pain and multiple dimensions of social relationship quality in a general population. Methods: A cross-sectional survey was deployed and adjusted logistic regression models were constructed for chronic pain against independent social support domains. The moderating effect of self-rated health on social support quality was explored. Results: Of all, 26.1% of surveys were completed (3920/15 000) and 18.8% reported clinically significant chronic pain. Patients with chronic pain had lower friendship quality (aOR = 0.78; 0.64-0.94) and higher perceived rejection (aOR = 1.26; 1.04-1.53) and perceived hostility (aOR = 1.26; 1.05-1.52). Within our moderation analysis, chronic pain patients with low self-rated health had higher odds of low friendship quality, high loneliness, and high perceived rejection. Conclusions: Chronic pain patients experience social relationships differently than those without, and self-rated health differentially impacts these perceptions.

Abstract Introduction Despite declines of cigarette use in the civilian population, military personnel report alarmingly high rates of cigarette use. Enlisted Air Force recruits are required to remain tobacco-free for the first 12 weeks of training, and the majority express confidence they will not use tobacco after the ban; however, most previous smokers return to smoking and many nonsmokers initiate. Understanding the factors associated with cigarette-smoking initiation among non-users and re-initiation among former users is critical for the development of successful tobacco control efforts. Materials and Methods The current study examines predictors of cigarette smoking among a sample of 2,188 USAF personnel after their first year of service. Logistic regression analyses examined associations between baseline predictors and initiation and re-initiation of cigarette smoking at a one-year follow-up. Results Compared to never smokers at both time points, the strongest predictor of smoking initiation over the past 12 months was having owned cigarette-branded merchandise (OR 3.81, 95% CI 1.67, 8.71). Compared to former smokers who remained abstinent, the strongest predictor of re-initiation was intention to use tobacco (OR 2.08, 95% CI 1.53, 2.83). Compared to individuals who initiate, the strongest predictors of re-initiation were prior use of other tobacco products and tobacco use intentions (ORs range 1.85 to 4.63). Conclusions Multiple risk factors are associated with tobacco use. Given that Airmen are tobacco-free for the first 12 weeks of training, tobacco interventions during this period might be more effective. Our findings can be used to tailor interventions to prevent tobacco use in the U.S. military.

Objectives: Clinicians recommend diet and exercise for overweight/obese patients. We conducted a secondary analysis of a randomized controlled clinical trial evaluating goal setting and pedometer use versus usual care on weight, waist circumference, and blood pressure of patients with multiple chronic conditions. Methods: In this trial, we recruited and randomized patients over 18 years with multiple chronic conditions. There were two groups with an immediate intervention group who received behavioral coaching and a pedometer versus a delayed control who received the intervention after 2 months. We evaluated body weight, waist circumference, and blood pressure as outcomes. We used analysis of covariance to evaluate differences between the intervention and the control groups. Results: Of 130 patients, mean age was 63.4 years (SD, 17.3). At 2 months, intervention participants lost 0.2 kg versus a 0.1-kg gain in the control participants ( P = .44). The immediate intervention group had significantly smaller waist circumference change at 2-month follow-up compared to control at −1.6 cm (95% confidence interval = −3.1 to −0.1), which was driven by an increase in waist circumference in the delayed control group. No difference in systolic blood pressure was observed. Discussion: We observed no difference in weight or blood pressure between the groups with obesity and multiple chronic conditions.

Objective To inform migraine care model development by assessing differences between patients with chronic migraine (CM) and episodic migraine (EM) in the current state of treatment, disability, patient satisfaction, and quality improvement opportunities. Background Efficient and focused use of scarce resources will be needed to address challenges within large populations of migraine patients. Methods We deployed a cross‐sectional survey study of randomly selected migraine patients within a community primary care practice. Results There were 516 survey respondents (516/1804 [30%] response rate). CM patients were more likely than EM patients to report care from a neurologist (76/110 [69%] vs 229/406 [56%]; P = .0026), and higher disability according to the Migraine Disability Assessment and Headache Impact Test – 6 questionnaires ( P < .0001). CM patients were less likely than EM patients to report overall satisfaction with care (16/110 [38%] vs 156/406 [66%], P = .0002), satisfaction with access to care (17/110 [33%] vs 176/406 [68%], P < .0001), and advice they needed (16/110 [31%] vs 160/406 [62%], P < .0001). Most patients with migraine had been offered triptan medications 377/516 (78%). Overall, 156/516 (31%) of individuals were currently taking any medication for migraine prevention, and 208/516 (40%) including botulinum toxin injections. CM patients were more likely to be taking preventive medication (39/110 [36%] vs 117/406 [29%], P = .0191) and report familiarity with the diagnosis of medication‐overuse headache than patients with EM (80/110 [81%] vs 256/406 [69%], P = .0178). Conclusions We observed differences between patients with chronic and EM and expected care delivery improvement opportunities for migraine patients in primary care. CM patients report higher levels of disability and less satisfaction with access to perceived needed medical advice and care. These findings support the need to further develop and study novel care models to efficiently and effectively deliver high‐quality care and expertise in limited supply to a diverse migraine population.

The societal burden of ischemic stroke suggests a need for additional therapeutic categories in stroke prevention. Modulation of the endocannabinoid system (ECS) is a rational target for stroke prevention because of its effects on inflammation, vascular tone, and metabolic balance, all well-described stroke risk factors. In this article, we summarize the existing ECS clinical studies in human subjects' research as they relate to conventional vascular risk factors associated with ischemic stroke. To date, 2-arachidonoylglycerol (2-AG) derivative endocannabinoids are consistently reported to be elevated in insulin resistance, whereas the N-arachidonoylethanolamine (AEA) endocannabinoid derivatives are elevated in obesity. The ECS role in metabolic health should examine the effects of 2-AG reduction and AEA augmentation as a means of stroke risk reduction. Cannabinoid receptors are reported on macrophages within atherosclerotic plaques and suggest a role for immunomodulation as a therapeutic for atherosclerosis through both peripheral immune cell CB1 antagonism and/or CB2 agonist. The effects of ECS on hypertension, smoking, physical activity, obstructive sleep apnea, heart failure, and atrial fibrillation are incompletely described and deserve further study. A limitation to ECS research is significant overlap with noncannabinoid molecular targets. Further exploration of the ECS needs to include the larger metabolomics context for a greater understanding of its therapeutic potential. Clinical translational studies in stroke prevention should be directed at ECS in metabolic balance and atherosclerosis.
