The impact of cigarette smoking on cognitive processing speed and brain atrophy in multiple sclerosis.

BACKGROUND: Smoking is associated with an increased risk of multiple sclerosis (MS) and disability worsening. The relationship between smoking, cognitive processing speed, and brain atrophy remains uncertain. OBJECTIVE: To quantify the impact of smoking on processing speed and brain volume in MS and to explore the longitudinal relationship between smoking and changes in processing speed. METHODS: A retrospective study of MS patients who completed the processing speed test (PST) between September 2015 and March 2020. Demographics, disease characteristics, smoking history, and quantitative magnetic resonance imaging (MRI) were collected. Cross-sectional associations between smoking, PST performance, whole-brain fraction (WBF), gray matter fraction (GMF), and thalamic fraction (TF) were assessed using multivariable linear regression. The longitudinal relationship between smoking and PST performance was assessed by linear mixed modeling. RESULTS: The analysis included 5536 subjects of whom 1314 had quantitative MRI within 90 days of PST assessment. Current smokers had lower PST scores than never smokers at baseline, and this difference persisted over time. Smoking was associated with reduced GMF but not with WBF or TF. CONCLUSION: Smoking has an adverse relationship with cognition and GMF. Although causality is not demonstrated, these observations support the importance of smoking cessation counseling in MS management.

Evaluation of Restrictions on Tobacco Sales to Youth Younger Than 21 Years in Cleveland, Ohio, Area.

Importance: Tobacco 21 (T21) policies raise the minimum legal age to purchase tobacco from 18 to 21 years to curb youth access to tobacco products. While some studies have found that T21 is associated with reducing prevalence of youth tobacco use, little is known about the impact it may have on youth of different racial and ethnic identities. Objective: To evaluate the association of T21 policy with the prevalence of high school youth tobacco use across sex, race, and ethnicity. Design, Setting, and Participants: This survey study used representative survey data collected from the local biennial Youth Risk Behavior Survey from 2013 to 2017 comparing Cleveland, Ohio (which has a T21 policy), to proximal jurisdictions in the first-ring suburbs in Cuyahoga County (which do not have T21 policies). Within-Cleveland demographic information was also collected for 2013 to 2019. Overall high school youth tobacco use rates were compared between Cleveland and the first-ring suburbs and then examined within Cleveland among Hispanic, non-Hispanic Black, and non-Hispanic White high school students. Percentage data were adjusted to more closely align with local population demographics. Data were analyzed from January to June 2022. Exposures: T21 was implemented in Cleveland in 2016 and not adopted in proximal jurisdictions or at the state and federal level until at least 1 year later. Main Outcomes and Measures: The main outcomes were prevalence of past 30-day cigarette, cigar product, or e-cigarette use, measured using geographically representative high school youth survey data from 2013 to 2015 (prelegislation) and 2017 to 2019 (postlegislation) and compared using a difference-in-differences analysis. Results: The unweighted sample included 12 616 high school students (27.0% [95% CI, 26.9%-28.0%] in 10th grade; 50.9% [95% CI, 50.3%-51.6%] females) participating in 1 or more Youth Risk Behavior Surveys from 2013 to 2019, including 7064 students in Cleveland and 5552 students in the first-ring suburbs. Compared with the first-ring suburbs, Cleveland had a greater proportion of younger students (1623 [28.5%] ninth grade students vs 2179 [34.0%] ninth grade students) and Hispanic students (436 students [1.1%] vs 1433 students [12.6%]) and non-Hispanic Black students (2000 students [53.1%] vs 3971 students [75.1%]). Cigars were the most commonly used tobacco product in Cleveland, with use reported by 6201 students (19.8%) in 2013, 5877 students (21.3%) in 2015, and 5784 students (16.8%) in 2019. Compared with the first-ring suburbs, there was a greater decline in prevalence of use of cigars in Cleveland (ß = 0.18 [SE, 0.05]; P < .001). The disparity across race, ethnicity, and sex decreased for all current tobacco product use. For example, the maximum difference between demographic subpopulations in current cigarette use was 11.6 (95% CI, 9.5-13.7) percentage points in 2013 between White females (16.1% [95% CI, 11.3%-20.8%]) and Black males (4.5% [95% CI, 3.5%-5.4%]). This maximum difference in current cigarette use decreased significantly to 5.1 (95% CI, 3.5-6.7) percentage points in 2019 between White females (6.9% [95% CI, 3.4%-10.3%]) and Black females (1.8% [95% CI, 0.7%-2.8%]). Conclusions and Relevance: This survey study found that there was a decline in youth-reported tobacco use across every tobacco product category from 2013 to 2019. This decline changed the trajectory of use among several demographic groups and brought the youth populations with the highest tobacco product use to similar rates of others.

Comparative Effectiveness of Stereotactic Electroencephalography Versus Subdural Grids in Epilepsy Surgery.

OBJECTIVE: The aim was to compare the outcomes of subdural electrode (SDE) implantations versus stereotactic electroencephalography (SEEG), the 2 predominant methods of intracranial electroencephalography (iEEG) performed in difficult-to-localize drug-resistant focal epilepsy. METHODS: The Surgical Therapies Commission of the International League Against Epilepsy created an international registry of iEEG patients implanted between 2005 and 2019 with ≥1 year of follow-up. We used propensity score matching to control exposure selection bias and generate comparable cohorts. Study endpoints were: (1) likelihood of resection after iEEG; (2) seizure freedom at last follow-up; and (3) complications (composite of postoperative infection, symptomatic intracranial hemorrhage, or permanent neurological deficit). RESULTS: Ten study sites from 7 countries and 3 continents contributed 2,012 patients, including 1,468 (73%) eligible for analysis (526 SDE and 942 SEEG), of whom 988 (67%) underwent subsequent resection. Propensity score matching improved covariate balance between exposure groups for all analyses. Propensity-matched patients who underwent SDE had higher odds of subsequent resective surgery (odds ratio [OR] = 1.4, 95% confidence interval [CI] 1.05, 1.84) and higher odds of complications (OR = 2.24, 95% CI 1.34, 3.74; unadjusted: 9.6% after SDE vs 3.3% after SEEG). Odds of seizure freedom in propensity-matched resected patients were 1.66 times higher (95% CI 1.21, 2.26) for SEEG compared with SDE (unadjusted: 55% seizure free after SEEG-guided resections vs 41% after SDE). INTERPRETATION: In comparison to SEEG, SDE evaluations are more likely to lead to brain surgery in patients with drug-resistant epilepsy but have more surgical complications and lower probability of seizure freedom. This comparative-effectiveness study provides the highest feasible evidence level to guide decisions on iEEG. ANN NEUROL 2021;90:927-939.

A cluster randomized trial evaluating a teachable moment communication process for tobacco cessation support.

INTRODUCTION: This study examines the uptake of a clinician-focused teachable moment communication process (TMCP) and its impact on patient receipt of tobacco cessation support. The TMCP is a counseling method that uses patient concerns to help clinicians guide behavior change discussions about tobacco. We evaluate the added value of the TMCP training in a health system that implemented an Ask-Advise-Connect (AAC) systems-based approach. METHODS: A stepped wedge cluster randomized trial included eight community health centers. Training involved a web module and onsite skill development with standardized patients and coaching. Main outcome measures included contact and enrollment in cessation services among patients referred for counseling, prescription of cessation medications and quit attempts. RESULTS: Forty-four of 60 eligible clinicians received the TMCP training. Among TMCP-trained clinicians 68% used a TMCP approach (documented by flowsheet use) one or more times, with the median number of uses being 15 (IQR 2-33). Overall, the TMCP was used in 661 out of 8198 visits by smokers (8%). There was no improvement in any of the tobacco cessation assistance outcomes for the AAC + TMCP vs. the AAC only period. Visits where clinicians used the TMCP approach were associated with increased ordering of tobacco cessation medications, (OR = 2.6; 95% CI = 1.9, 3.5) and providing advice to quit OR 3.2 (95% CI 2.2, 4.7). CONCLUSIONS: Despite high fidelity to the training, uptake of the TMCP approach in routine practice was poor, making it difficult to evaluate the impact on patient outcomes. When the TMCP approach was used, ordering tobacco cessation medications increased. IMPLICATIONS: Tobacco cessation strategies in primary care have the potential to reach a large portion of the population and deliver advice tailored to the patient. The poor uptake of the approach despite high training fidelity suggests that additional implementation support strategies, are needed to increase sustainable adoption of the TMCP approach.

12-Month Evaluation of an EHR-Supported Staff Role Change for Provision of Tobacco Cessation Care in 8 Primary Care Safety-Net Clinics.

SIGNIFICANCE: Guidelines urge primary care practices to routinely provide tobacco cessation care (i.e., assess tobacco use, provide brief cessation advice, and refer to cessation support). This study evaluates the impact of a systems-based strategy to provide tobacco cessation care in eight primary care clinics serving low-income patients. METHODS: A non-randomized stepped wedge study design was used to implement an intervention consisting of (1) changes to the electronic health record (EHR) referral functionality and (2) expansion of staff roles to provide brief advice to quit; assess readiness to quit; offer a referral to tobacco cessation counseling; and sign the referral order. Outcomes assessed from the EHR include performance of tobacco cessation care tasks, referral contact, and enrollment rates for the quitline (QL) and in-house Freedom from Smoking (FFS) program. Generalized estimating equations (GEE) methods were used to compute odds ratios contrasting the pre-implementation vs. 1-, 3-, 6-, and 12-month post-implementation periods. RESULTS: Of the 176,061 visits, 26.1% were by identified tobacco users. All indicators significantly increased at each time period evaluated post-implementation. In comparison with the pre-intervention period, assessing smoking status (26.6% vs. 55.7%; OR = 3.7, CI = 3.6-3.9), providing advice (44.8% vs. 88.7%; OR = 7.8, CI = 6.6-9.1), assessing readiness to quit (15.8% vs. 55.0%; OR = 6.2, CI = 5.4-7.0), and acceptance of a referral to tobacco cessation counseling (0.5% vs. 30.9%; OR = 81.0, CI = 11.4-575.8) remained significantly higher 12 months post-intervention. For the QL and FFS, respectively, there were 1223 and 532 referrals; 324 (31.1%) and 103 (24.7%) were contacted; 241 (74.4%) and 72 (69.6%) enrolled; and 195 (80.9%) and 14 (19.4%) received at least one counseling session. CONCLUSIONS: This system change intervention that includes an EHR-supported role expansion substantially increased the provision of tobacco cessation care and improvements were sustained beyond 1 year. This approach has the potential to greatly increase the number of individuals referred for tobacco cessation counseling.

Designing for Sustainability: An Approach to Integrating Staff Role Changes and Electronic Health Record Functionality Within Safety-Net Clinics to Address Provision of Tobacco Cessation Care.

BACKGROUND: Guidelines urge primary care practices to routinely provide tobacco cessation care, but quality indicators for the provision of advice and assistance to quit smoking lag. This study evaluated the implementation of a systems-based strategy to improve performance of tobacco cessation care in primary care clinics. METHODS: Changes to the electronic health record (EHR) facilitated staff to document when they ask about tobacco use, advise the patient to quit, offer to connect the patient to a quitline (QL) counselor, and refer interested patients to receive a call from a QL. Medical assistants (MAs) were trained to use the new sections of the EHR, and their roles were expanded to include the provision of brief cessation advice and activation of the QL referral. Primary outcomes were change in tobacco cessation processes preimplementation vs. one, three, and six months postimplementation of the strategy. RESULTS: The increase in performance of tobacco cessation care was significant and sustained at six months postimplementation for assessing smoking status (50.9% vs. 76.3%; odds ratio [OR] = 3.04; 95% confidence interval [CI] = 2.80-3.31), providing advice (15.1% vs. 92.7%; OR = 69.3; 95% CI = 51.88-92.60), assessing readiness to quit (22.8% vs. 76.6%; OR = 10.80; 95% CI = 8.92-13.08), and accepting a referral to the QL (1.3% vs. 21.7%; OR = 20.31; 95% CI = 4.91-84.05). CONCLUSION: Key stakeholder engagement informed a system change intervention that includes an EHR-supported role expansion of MAs for QL referrals; these changes substantially increased the provision of tobacco cessation care.

Electronic medical record documentation of tobacco cessation support at eight community safety-net clinics with a high prevalence of tobacco use.

OBJECTIVES: The high prevalence of tobacco use at primary care safety-net clinics represents an opportunity to offer assistance with cessation. Documentation of smoking status, offering advice and medications, and referral to cessation services are important steps in supporting cessation attempts and are required elements by payors and accrediting agencies to demonstrate care quality. This study examines tobacco cessation support rates and patient characteristics using electronic medical record (EMR) data. METHODS: This cross-sectional study engaged eight community health centers affiliated with a county hospital system in NE Ohio where adult tobacco use rates exceed 30%. EMR data from June 2014 through May 2016 were analysed to assess rates of tobacco cessation counselling, order of cessation medications, or both. The association of tobacco cessation support with patient characteristics and quit attempts was assessed using multivariable logistic regression models. RESULTS: Among 21 702 current tobacco users, 74% had no intervention documented; 15.4% had counselling documented, 6.4% were prescribed tobacco cessation medication, and 4.2% had both documented. Males, those aged 18 to 34, and African Americans were more likely to have no documented intervention. Of current tobacco users with at least two visits, 5.6% had a quit attempt. Medication alone was associated with a greater likelihood of a quit attempt (AOR: 1.72 [95% CI: 1.36-2.17]) as well as counselling and medication combined (AOR: 1.95 [95% CI: 1.48-2.56]). CONCLUSIONS: Tobacco cessation support was lacking for 74% of current smokers and was less likely in subgroups including males, younger adults, and African Americans. Ordering tobacco cessation medication combined with counselling nearly doubled the likelihood of a quit attempt.

Long-term reduction of health care costs and utilization after epilepsy surgery.

OBJECTIVE: To assess long-term direct medical costs, health care utilization, and mortality following resective surgery in persons with uncontrolled epilepsy. METHODS: Retrospective longitudinal cohort study of Medicaid beneficiaries with epilepsy from 2000 to 2008. The study population included 7,835 persons with uncontrolled focal epilepsy ages 18-64 years, with an average follow-up time of 5 years. Of these, 135 received surgery during the study period. To account for selection bias, we used risk-set optimal pairwise matching on a time-varying propensity score, and inverse probability of treatment weighting. Repeated measures generalized linear models were used to model utilization and cost outcomes. Cox proportional hazard was used to model survival. RESULTS: The mean direct medical cost difference between the surgical group and control group was $6,806 after risk-set matching. The incidence rate ratio of inpatient, emergency room, and outpatient utilization was lower among the surgical group in both unadjusted and adjusted analyses. There was no significant difference in mortality after adjustment. Among surgical cases, mean annual costs per subject were on average $6,484 lower, and all utilization measures were lower after surgery compared to before. SIGNIFICANCE: Subjects that underwent epilepsy surgery had lower direct medical care costs and health care utilization. These findings support that epilepsy surgery yields substantial health care cost savings.

Empirical Treatment Effectiveness Models for Binary Outcomes.

Randomized trials provide strong evidence regarding efficacy of interventions but are limited in their capacity to address potential heterogeneity in effectiveness within broad clinical populations. For example, a treatment that on average is superior may be distinctly worse in certain patients. We propose a technique for using large electronic health registries to develop and validate decision models that measure-for distinct combinations of covariate values-the difference in predicted outcomes among 2 alternative treatments. We demonstrate the methodology in a prototype analysis of in-hospital mortality under alternative revascularization treatments. First, we developed prediction models for a binary outcome of interest for each treatment. Decision criteria were then defined based on the treatment-specific model predictions. Patients were then classified as receiving concordant or discordant care (in relation to the model recommendation), and the association between discordance and outcomes was evaluated. We then present alternative decision criteria and validation methodologies, as well as sensitivity analyses that investigate 1) the imbalance between treatments on observed covariates and 2) the aggregate impact of unobserved covariates. Our methodology supplements population-average clinical trial results by modeling heterogeneity in outcomes according to specific covariate values. It thus allows for assessment of current practice, from which cogent hypotheses for improved care can be derived. Newly emerging large population registries will allow for accurate predictions of outcome risk under competing treatments, as complex functions of predictor variables. Whether or not the models might be used to inform decision making depends on the extent to which important predictors are available. Further work is needed to understand the strengths and limitations of this approach, particularly in relation to those based on randomized trials.

Effect of invasive EEG monitoring on cognitive outcome after left temporal lobe epilepsy surgery.

OBJECTIVES: The objective of this cohort study was to compare neuropsychological outcomes following left temporal lobe resection (TLR) in patients with epilepsy who had or had not undergone prior invasive monitoring. METHODS: Data were obtained from an institutional review board-approved, neuropsychology registry for patients who underwent epilepsy surgery at Cleveland Clinic between 1997 and 2013. A total of 176 patients (45 with and 131 without invasive EEG) met inclusion criteria. Primary outcome measures were verbal memory and language scores. Other cognitive outcomes were also examined. Outcomes were assessed using difference in scores from before to after surgery and by presence/absence of clinically meaningful decline using reliable change indices (RCIs). Effect of invasive EEG on cognitive outcomes was estimated using weighting and propensity score adjustment to account for differences in baseline characteristics. Linear and logistic regression models compared surgical groups on all cognitive outcomes. RESULTS: Patients with invasive monitoring showed greater declines in confrontation naming; however, when RCIs were used to assess clinically meaningful change, there was no significant treatment effect on naming performance. No difference in verbal memory was observed, regardless of how the outcome was measured. In secondary outcomes, patients with invasive monitoring showed greater declines in working memory, which were no longer apparent using RCIs to define change. There were no outcome differences on other cognitive measures. CONCLUSIONS: Results suggest that invasive EEG monitoring conducted prior to left TLR is not associated with greater cognitive morbidity than left TLR alone. This information is important when counseling patients regarding cognitive risks associated with this elective surgery.

Disparities in access to specialized epilepsy care.

OBJECTIVE: To examine the impact of individual and community characteristics on access to specialized epilepsy care. METHODS: This retrospective cross-sectional study analyzed data from the California State Inpatient Sample, the State Ambulatory Surgery Database, and the State Emergency Department Database, that were linked with the 2009 Area Resource File and the location of the National Association of Epilepsy Center's epilepsy centers. The receipt of video-EEG monitoring was measured and used to indicate access to specialized epilepsy care in subjects with persistent seizures, identified as those who had frequent seizure-related hospital admissions and/or ER visits. A hierarchical logistic regression model was employed to assess barriers to high quality care at both individual and contextual levels. RESULTS: Among 115,632 persons with persistent seizures, individuals who routinely received care in an area where epilepsy centers were located were more likely to have access to specialized epilepsy care (OR: 1.81, 95% CI: 1.20, 2.72). Interestingly, the availability of epilepsy centers did not influence access to specialized epilepsy care in people who had private insurance. In contrast, uninsured individuals and those with public insurance programs including Medicaid and Medicare had significant gaps in access to specialized epilepsy care. Other individual characteristics such as age, race/ethnicity, and the presence of comorbid conditions were also associated with disparities in access to specialized care in PWE. CONCLUSION: Both individual and community characteristics play substantial roles in access to high quality epilepsy care. Policy interventions that incorporate strategies to address disparities at both levels are necessary to improve access to specialized care for PWE.

Use and perceived value of health information exchange: one public healthcare system's experience.

OBJECTIVES: To describe health information exchange (HIE) use and providers' perceptions of value in a public healthcare system using a commercial electronic health record (EHR). STUDY DESIGN: Observational study of HIE implementation and cross-sectional provider survey. METHODS: We identified characteristics (age, gender, race/ethnicity, insurance type, comorbid conditions) and the care setting (primary care; emergency department [ED] or inpatient care; or specialty care) for patients with and without HIE. Associations between patient characteristics and HIE were examined using a multivariate logistic regression. Provider perceptions were assessed via confidential survey. RESULTS: During its first 14 months, 11,960 HIEs occurred among 9399 patients. Rates of HIE use were 13/1000 visits overall (20/1000 in primary care, 36/1000 in the ED/inpatient setting, and 5/1000 in specialty settings [P <.001]). Patients with HIE were older, more often female, African American, had more chronic conditions, and more often had Medicaid or Medicare insurance (P <.001). HIE was used least among commercially insured (odds ratio, 0.78, 95% confidence interval,0.73-0.83, compared with uninsured). Among the 18% (74/412) of survey respondents, 93% "disagreed/strongly disagreed" that obtaining consent was difficult and 97% reported no patient refusals. Respondents "agreed/strongly agreed" that HIE fostered more efficient care (93%), saved time (85%), decreased laboratory (84%) and imaging (74%) use, and 15% stated that HIE prevented an unnecessary admission. CONCLUSION: Early HIE use varied by care setting, patient characteristics, and insurance. Providers perceived HIE acceptable to patients, and helpful in avoiding redundant testing and unnecessary hospitalizations. Lower HIE use among commercially insured patients reinforces concerns that financial incentives may inhibit adoption.

Association between smoking and outcomes in older adults with atrial fibrillation.

Tobacco smoking is a risk factor for atrial fibrillation (AF), but little is known about the impact of smoking in patients with AF. Of the 4060 patients with recurrent AF in the Atrial Fibrillation Follow-up Investigation of Rhythm Management (AFFIRM) trial, 496 (12%) reported having smoked during the past two years. Propensity scores for smoking were estimated for each of the 4060 patients using a multivariable logistic regression model and were used to assemble a matched cohort of 487 pairs of smokers and nonsmokers, who were balanced on 46 baseline characteristics. Cox and logistic regression models were used to estimate the associations of smoking with all-cause mortality and all-cause hospitalization, respectively, during over 5 years of follow-up. Matched participants had a mean age of 70 ± 9 years (± S.D.), 39% were women, and 11% were non-white. All-cause mortality occurred in 21% and 16% of matched smokers and nonsmokers, respectively (when smokers were compared with nonsmokers, hazard ratio=HR=1.35; 95% confidence interval=95%CI=1.01-1.81; p=0.046). Unadjusted, multivariable-adjusted and propensity-adjusted HR (95% CI) for all-cause mortality associated with smoking in the pre-match cohort were: 1.40 (1.13-1.72; p=0.002), 1.45 (1.16-1.81; p=0.001), and 1.39 (1.12-1.74; p=0.003), respectively. Smoking had no association with all-cause hospitalization (when smokers were compared with nonsmokers, odds ratio=OR=1.21; 95%CI=0.94-1.57, p=0.146). Among patients with AF, a recent history of smoking was associated with an increased risk of all-cause mortality, but had no association with all-cause hospitalization.

Comparison of cold and warm ischemia during partial nephrectomy in 660 solitary kidneys reveals predominant role of nonmodifiable factors in determining ultimate renal function.

PURPOSE: Factors that determine renal function after partial nephrectomy are not well-defined, including the impact of cold vs warm ischemia, and the relative importance of modifiable and nonmodifiable factors. We studied these determinants in a large cohort of patients with a solitary functioning kidney undergoing partial nephrectomy. MATERIALS AND METHODS: From 1980 to 2009, 660 partial nephrectomies were performed at 4 centers for tumor in a solitary functioning kidney under cold (300) or warm (360) ischemia. Data were collected in institutional review board approved registries and followup averaged 4.5 years. Preoperative and postoperative glomerular filtration rates were estimated via the Chronic Kidney Disease-Epidemiology Study equation. RESULTS: At 3 months after partial nephrectomy median glomerular filtration rate decreased by equivalent amounts with cold or warm ischemia (21% vs 22%, respectively, p = 0.7), although median cold ischemic times were much longer (45 vs 22 minutes respectively, p <0.001). On multivariable analyses increasing age, larger tumor size, lower preoperative glomerular filtration rate and longer ischemia time were associated with decreased postoperative glomerular filtration rate (p <0.05). When percentage of parenchyma spared was incorporated into the analysis, this factor and preoperative glomerular filtration rate proved to be the primary determinants of ultimate renal function, and duration of ischemia lost statistical significance. CONCLUSIONS: This nonrandomized, comparative study suggests that within the relatively strict parameters of conventional practice, ie predominantly short ischemic intervals and liberal use of hypothermia, ischemia time was not an independent predictor of ultimate renal function after partial nephrectomy. Long-term renal function after partial nephrectomy is determined primarily by the quantity and quality of renal parenchyma preserved, although type and duration of ischemia remain the most important modifiable factors, and warrant further study.

History of cancer and mortality in community-dwelling older adults.

BACKGROUND: The association between a history of cancer and mortality has not been studied in a propensity-matched population of community-dwelling older adults. METHODS: Of the 5795 participants in the Cardiovascular Health Study, 827 (14%) had self-reported physician-diagnosed cancer at baseline. Propensity scores for cancer were used to assemble a cohort of 789 and 3118 participants with and without cancer respectively who were balanced on 45 baseline characteristics. Cox regression models were used to determine the association between cancer and all-cause mortality among matched patients, and to identify independent predictors of mortality among unmatched cancer patients. RESULTS: Matched participants had a mean (SD) age of 74 (6) years, 57% were women, 10% were African Americans, and 38% died from all causes during 12 years of follow-up. All-cause mortality occurred in 41% and 37% of matched participants with and without a history of cancer respectively (hazard ratio when cancer was compared with no cancer, 1.16; 95% confidence interval, 1.02-1.31; P=0.019). Among those with cancer, older age, male gender, smoking, lower than college education, fair-to-poor self-reported health, coronary artery disease, diabetes mellitus, chronic kidney disease, left ventricular hypertrophy, increased heart rate, low hemoglobin and low baseline albumin were associated with increased risk of mortality. CONCLUSIONS: Among community-dwelling older adults, a history of cancer was associated with increased mortality and among those with cancer, several socio-demographic variables and morbidities predicted mortality. These findings suggest that addressing traditional risk factors for cardiovascular mortality may help improve outcomes in older adults with a history of cancer.

Coronary artery disease, coronary revascularization, and outcomes in chronic advanced systolic heart failure.

BACKGROUND: Associations between coronary artery disease (CAD) and outcomes in systolic heart failure (HF) and that between coronary artery bypass graft (CABG) surgery and outcomes in patients with HF and CAD have not been examined using propensity-matched designs. METHODS: Of the 2707 patients with advanced chronic systolic HF in the Beta-Blocker Evaluation of Survival Trial (BEST), 1593 had a history of CAD, of whom 782 had prior CABG. Using propensity scores for CAD we assembled a cohort of 458 pairs of CAD and no-CAD patients. Propensity scores for prior CABG in those with CAD were used to assemble 500 pairs of patients with and without CABG. Matched patients were balanced on 68 baseline characteristics. RESULTS: All-cause mortality occurred in 33% and 24% of matched patients with and without CAD respectively, during 26 months of median follow-up (hazard ratio {HR} when CAD was compared with no-CAD, 1.41; 95% confidence interval {CI}, 1.11-1.81; P=0.006). HR's (95% CIs) for CAD-associated cardiovascular mortality, HF mortality, and sudden cardiac death (SCD) were 1.53 (1.17-2.00; P=0.002), 1.44 (0.92-2.25; P=0.114) and 1.76 (1.21-2.57; P=0.003) respectively. CAD had no association with hospitalization. Among matched patients with HF and CAD, all-cause mortality occurred in 32% and 39% of those with and without prior CABG respectively (HR for CABG, 0.77; 95% CI, 0.62-0.95; P=0.015). CONCLUSIONS: In patients with advanced chronic systolic HF, CAD is associated with increased mortality, and in those with CAD, prior CABG seems to be associated with reduced all-cause mortality but not SCD.

Patient age, well-being, perspectives, and care practices in the early treatment phase for late-stage cancer.

BACKGROUND: Among advanced-stage cancer patients, age is an important determinant of decision making about medical care. We examined age-related differences in patient well-being, care perspectives, and preferences, and the relationship between these patient characteristics and subsequent care practices including care communication, pain management, and acute care utilization during the early treatment phase of late-stage cancer. METHODS: Patient demographics, well-being, and care perspectives were assessed during patient and physician baseline interviews. Care practices were measured using outpatient and inpatient records for the 30-day period after baseline assessment. Multivariate regression models were used to examine the patterns of association of age and other patient characteristics with care practices. RESULTS: A total of 174 middle-aged and 149 older patients with recently diagnosed late-stage cancer were included. Older patients had more comorbidities but lower levels of depression, anxiety, and symptom distress. Older patients preferred pain relief/comfort as a treatment goal, but received fewer prescriptions for opioids. Whereas provider-initiated communication with patients/families was positively associated with severity of illness, patient/family-initiated communication was associated with patient psychosocial attributes and care perspectives. Satisfaction with care was inversely associated with reports of pain. Symptom distress was positively associated with subsequent opioid prescriptions and hospitalizations. CONCLUSIONS: Our results help to explain the role of patients' psychosocial attributes, care perspectives, and preferences in subsequent care practices during the early treatment phase for late-stage cancer. Age-related differences in patient well-being and care perspectives suggest a role for age-sensitive interventions in the treatment of advanced cancer patients.

The efficiency of endoscopic pancreatic function testing is optimized using duodenal aspirates at 30 and 45 minutes after intravenous secretin.

OBJECTIVES: The endoscopic secretin test (ePFT) takes an hour to perform, limiting its practicality for routine use. We sought to determine which timed endoscopic collections best predict the peak bicarbonate concentration from full hour-long test. METHODS: A cross-sectional study was performed of all ePFTs performed at our institution from 2000 to 2004. We compared 7 theoretical shortened tests [4-single collections (15, 30, 45, or 60 minutes after secretin) and 3-dual collections (15/30, 30/45, 45/60 minutes after secretin)] to the full test and to each other using multivariate linear and Deming regression models. RESULTS: The bicarbonate results of 240 ePFTs were analyzed. The dual 30/45-minute collection was the optimal method based on the closest agreement with the full test (94%). Deming regression reveals the 30/45 estimate to be the best combination from an analytic perspective, owing to its lack of significant proportional bias and minimal constant bias (5.1 mEq/L) as compared to the reference test. Use of the 30/45 method with the adjusted cutpoint 75 mEq/L produces very good specificity (93%) for ruling in exocrine insufficiency. CONCLUSIONS: A dual timed aspiration at 30 and 45 minutes can be used to screen for pancreatic exocrine insufficiency in patients with abdominal pain, simplifying the use of the ePFT in clinical practice.
