2009· New England Journal of Medicine1.1Kdoi:10.1056/nejmoa0902905

BACKGROUND: Coronary-artery bypass grafting (CABG) has traditionally been performed with the use of cardiopulmonary bypass (on-pump CABG). CABG without cardiopulmonary bypass (off-pump CABG) might reduce the number of complications related to the heart-lung machine. METHODS: We randomly assigned 2203 patients scheduled for urgent or elective CABG to either on-pump or off-pump procedures. The primary short-term end point was a composite of death or complications (reoperation, new mechanical support, cardiac arrest, coma, stroke, or renal failure) before discharge or within 30 days after surgery. The primary long-term end point was a composite of death from any cause, a repeat revascularization procedure, or a nonfatal myocardial infarction within 1 year after surgery. Secondary end points included the completeness of revascularization, graft patency at 1 year, neuropsychological outcomes, and the use of major resources. RESULTS: There was no significant difference between off-pump and on-pump CABG in the rate of the 30-day composite outcome (7.0% and 5.6%, respectively; P=0.19). The rate of the 1-year composite outcome was higher for off-pump than for on-pump CABG (9.9% vs. 7.4%, P=0.04). The proportion of patients with fewer grafts completed than originally planned was higher with off-pump CABG than with on-pump CABG (17.8% vs. 11.1%, P<0.001). Follow-up angiograms in 1371 patients who underwent 4093 grafts revealed that the overall rate of graft patency was lower in the off-pump group than in the on-pump group (82.6% vs. 87.8%, P<0.01). There were no treatment-based differences in neuropsychological outcomes or short-term use of major resources. CONCLUSIONS: At 1 year of follow-up, patients in the off-pump group had worse composite outcomes and poorer graft patency than did patients in the on-pump group. No significant differences between the techniques were found in neuropsychological outcomes or use of major resources. (ClinicalTrials.gov number, NCT00032630.).

IMPORTANCE: Less than one-third of patients with major depressive disorder (MDD) achieve remission with their first antidepressant. OBJECTIVE: To determine the relative effectiveness and safety of 3 common alternate treatments for MDD. DESIGN, SETTING, AND PARTICIPANTS: From December 2012 to May 2015, 1522 patients at 35 US Veterans Health Administration medical centers who were diagnosed with nonpsychotic MDD, unresponsive to at least 1 antidepressant course meeting minimal standards for treatment dose and duration, participated in the study. Patients were randomly assigned (1:1:1) to 1 of 3 treatments and evaluated for up to 36 weeks. INTERVENTIONS: Switch to a different antidepressant, bupropion (switch group, n = 511); augment current treatment with bupropion (augment-bupropion group, n = 506); or augment with an atypical antipsychotic, aripiprazole (augment-aripiprazole group, n = 505) for 12 weeks (acute treatment phase) and up to 36 weeks for longer-term follow-up (continuation phase). MAIN OUTCOMES AND MEASURES: The primary outcome was remission during the acute treatment phase (16-item Quick Inventory of Depressive Symptomatology-Clinician Rated [QIDS-C16] score ≤5 at 2 consecutive visits). Secondary outcomes included response (≥50% reduction in QIDS-C16 score or improvement on the Clinical Global Impression Improvement scale), relapse, and adverse effects. RESULTS: Among 1522 randomized patients (mean age, 54.4 years; men, 1296 [85.2%]), 1137 (74.7%) completed the acute treatment phase. Remission rates at 12 weeks were 22.3% (n = 114) for the switch group, 26.9% (n = 136)for the augment-bupropion group, and 28.9% (n = 146) for the augment-aripiprazole group. The augment-aripiprazole group exceeded the switch group in remission (relative risk [RR], 1.30 [95% CI, 1.05-1.60]; P = .02), but other remission comparisons were not significant. Response was greater for the augment-aripiprazole group (74.3%) than for either the switch group (62.4%; RR, 1.19 [95% CI, 1.09-1.29]) or the augment-bupropion group (65.6%; RR, 1.13 [95% CI, 1.04-1.23]). No significant treatment differences were observed for relapse. Anxiety was more frequent in the 2 bupropion groups (24.3% in the switch group [n = 124] vs 16.6% in the augment-aripiprazole group [n = 84]; and 22.5% in augment-bupropion group [n = 114]). Adverse effects more frequent in the augment-aripiprazole group included somnolence, akathisia, and weight gain. CONCLUSIONS AND RELEVANCE: Among a predominantly male population with major depressive disorder unresponsive to antidepressant treatment, augmentation with aripiprazole resulted in a statistically significant but only modestly increased likelihood of remission during 12 weeks of treatment compared with switching to bupropion monotherapy. Given the small effect size and adverse effects associated with aripiprazole, further analysis including cost-effectiveness is needed to understand the net utility of this approach.

2015· BMC Cancer92doi:10.1186/s12885-015-1038-y

BACKGROUND: Given the paucity of information on dose intensity, the objective of this study is to describe the use of adjuvant chemotherapy for stage III colon cancer, focusing on relative dose intensity (RDI), overall survival (OS) and disease-free survival (DFS). METHODS: Retrospective cohort of 367 patients diagnosed with stage III colon cancer in 2003-2008 and treated at 19 VA medical centers. Kaplan-Meier curves summarize 5-year OS and 3-year DFS by chemotherapy regimen and RDI, and multivariable Cox proportional hazards regression was used to model these associations. RESULTS: 5-fluorouracil/leucovorin (FU/LV) was the most commonly initiated regimen in 2003 (94.4%) and 2004 (62.7%); in 2005-2008, a majority of patients (60%-74%) was started on an oxaliplatin-based regimen. Median RDI was 82.3%. Receipt of >70% RDI was associated with better 5-year OS (p < 0.001) and 3-year DFS (P = 0.009) than was receipt of ≤70% RDI, with 5-year OS rates of 66.3% and 50.5%, respectively and 3-year DFS rates of 66.1% and 52.7%, respectively. In the multivariable analysis of 5-year OS, oxaliplatin + 5-FU/LV (versus 5-FU/LV) (HR = 0.55; 95% CI = 0.34-0.91), >70% RDI at the first year (HR = 0.58; 95% CI = 0.37-0.89) and married status (HR = 0.66; 95% CI = 0.45-0.97) were associated with significantly decreased risk of death, while age ≥75 (versus 55-64) (HR = 2.06; 95% CI = 1.25-3.40), Charlson Comorbidity Index (HR = 1.17; 95% CI = 1.06-1.30), T4 tumor status (versus T1/T2) (HR = 5.88; 95% CI = 2.69-12.9), N2 node status (HR = 1.68; 95% CI = 1.12-2.50) and bowel obstruction (HR = 2.32, 95% CI = 1.36-3.95) were associated with significantly increased risk. Similar associations were observed for DFS. CONCLUSION: Patients with stage III colon cancer who received >70% RDI had improved 5-year OS. The association between RDI and survival needs to be examined in studies of adjuvant chemotherapy for colon cancer outside of the VA.

Mentoring is a developmental experience intended to increase the willingness to learn and establish credibility while building positive relationships through networking. In this commentary, we focus on intentional mentoring for underrepresented mentees, including individuals that belong to minority racial, ethnic and gender identity groups in Science, Technology, Engineering, Mathematics and Medicine (STEMM) fields. Intentional mentoring is the superpower action necessary for developing harmony and comprehending the purpose and value of the mentor/mentee relationship. Regardless of a mentor's career stage, we believe the strategies discussed may be used to create a supportive and constructive mentorship environment; thereby improving the retention rates of underrepresented mentees within the scientific community.

1982· Cancer71doi:10.1002/1097-0142(19820815)50:4<646::aid-cncr2820500405>3.0.co;2-0

A randomized trial of 381 patients with extensive lung cancer compared immunochemotherapy with levamisole (150 mg/m2 orally three times a week), cyclophosphamide (700 mg/m2 IV every three weeks) and CCNU (70 mg/m2 orally every six weeks) with the same chemotherapy without levamisole. When disease progressed, doxorubicin hydrochloride or doxorubicin hydrochloride plus levamisole was used. Hematologic toxicity required reduction of the levamisole dosage to 2.5 mg/kg (100 mg/m2) three times a week, every other week. When corrections are made for all variables, levamisole itself had a negative influence on survival. Patients given 150 mg/m2 had a shorter median time to treatment failure (P = 0.02), lower response rate (P = 0.02) more toxicity (P = 0.08), and shorter median survival (P = 0.08). Patients with 10% or greater weight loss had significantly shorter survival (P = 0.006). The regimen with the reduced dosage of levamisole also was more toxic (P = 0.05) but otherwise did not differ from the control regimen. The cause of the adverse effect of levamisole is unknown. It did not occur because of an excess of toxic deaths or because smaller doses of cytotoxic drugs were given to patients treated with levamisole. Neither the initial lymphocyte count nor the Candida skin test reactions had a significant effect on the study endpoints when correction was made for dominant prognostic factors such as the initial performance status and weight loss.

2013· Journal of the American Geriatrics Society69doi:10.1111/jgs.12550

OBJECTIVES: To determine whether an intervention that improves nursing home (NH) staff connections, communication, and problem solving (CONNECT) would improve implementation of a falls reduction education program (FALLS). DESIGN: Cluster randomized trial. SETTING: Community (n=4) and Veterans Affairs (VA) NHs (n=4). PARTICIPANTS: Staff in any role with resident contact (n=497). INTERVENTION: NHs received FALLS alone (control) or CONNECT followed by FALLS (intervention), each delivered over 3 months. CONNECT used storytelling, relationship mapping, mentoring, self-monitoring, and feedback to help staff identify communication gaps and practice interaction strategies. FALLS included group training, modules, teleconferences, academic detailing, and audit and feedback. MEASUREMENTS: NH staff completed surveys about interactions at baseline, 3 months (immediately after CONNECT or control period), and 6 months (immediately after FALLS). A random sample of resident charts was abstracted for fall risk reduction documentation (n=651). Change in facility fall rates was an exploratory outcome. Focus groups were conducted to explore changes in organizational learning. RESULTS: Significant improvements in staff perceptions of communication quality, participation in decision-making, safety climate, caregiving quality, and use of local interaction strategies were observed in intervention community NHs (treatment-by-time effect P=.01) but not in VA NHs, where a ceiling effect was observed. Fall risk reduction documentation did not change significantly, and the direction of change in individual facilities did not relate to observed direction of change in fall rates. Fall rates did not change in control facilities (falls/bed per year: baseline, 2.61; after intervention, 2.64) but decreased by 12% in intervention facilities (falls/bed per year: baseline, 2.34; after intervention, 2.06); the effect of treatment on rate of change was 0.81 (95% confidence interval=0.55-1.20). CONCLUSION: CONNECT has the potential to improve care delivery in NHs, but the trend toward improving fall rates requires confirmation in a larger ongoing study.

A collagen coated vascular prosthesis.

A woven, double velour Dacron vascular graft was made nonporous by coating it with a layer of collagen prepared from fresh, young calf skin. Grafts were implanted in the thoracic aorta of 24 mongrel dogs and were examined at intervals up to 180 days. The grafts did not require preclotting or special preparation before being implanted. They sutured easily and did not bleed. When explanted all grafts were patent and covered with neointima. The bovine collagen was almost completely resorbed by 90 days and was replaced with native tissue. The collagen was neither thrombogenic, antigenic, cytotoxic, or pyrogenic.

PURPOSE: Tracking changes in care utilization of medication for opioid use disorder (MOUD) services before, during, and after COVID-19-associated changes in policy and service delivery in a mixed rural and micropolitan setting. METHODS: Using a retrospective, open-cohort design, we examined visit data of MOUD patients at a family medicine clinic across three identified periods: pre-COVID, COVID transition, and COVID. Outcome measures include the number and type of visits (in-person or telehealth), the number of new patients entering treatment, and the number of urine drug screens performed. Distance from patient residence to clinic was calculated to assess access to care in rural areas. Goodness-of-Fit Chi-Square tests and ANOVAs were used to identify differences between time periods. FINDINGS: Total MOUD visits increased during COVID (436 pre vs. 581 post, p < 0.001), while overall new patient visits remained constant (33 pre vs. 29 post, p = 0.755). The clinic's overall catchment area increased in size, with new patients coming primarily from rural areas. Length of time between urine drug screens increased (21.1 days pre vs. 43.5 days post, p < 0.001). CONCLUSIONS: The patterns of MOUD care utilization during this period demonstrate the effectiveness of telehealth in this area. Policy changes allowing for MOUD to be delivered via telehealth, waiving the need for in-person initiation of MOUD, and increased Medicaid compensation for MOUD may play a valuable role in improving access to MOUD during the COVID-19 pandemic and beyond.

Although family home care problems are frequently described in the health care literature, the ways in which families and other informal caregivers manage those problems are not often addressed. We conducted a descriptive analysis of interviews in which spouses caring for a partner with Alzheimer's or Parkinson's disease were asked to describe difficult home care problems and how they managed those problems. Analysis of these interviews indicated three recurring management styles. Adapters told stories about applying pre-existing skills to manage home care problems. Strugglers told stories of reoccurring home care problems for which they had few or no management strategies. Case managers' interview stories focused on the challenges of finding and coordinating home care services. These findings suggest that caregiving burden might be influenced more by the caregiver's management style than the demands of the care situation. Suggestions for tailoring support programs for the three types of caregivers are proposed.

1988· PubMed42

In a prospective randomized trial, 468 patients with unstable angina pectoris who were stratified according to clinical presentation (Type I or Type II angina) and left ventricular function (normal or abnormal) were assigned to medical or surgical treatment groups. Left ventricular function was defined as abnormal if the ejection fraction was less than 0.50, or if the end-diastolic pressure was 16 mm Hg or greater. Left ventricular function was abnormal in 134 patients, 66 of whom were assigned to surgical and 68 to medical treatment groups. The cumulative 3-year mortality for surgical patients was 6.1% and for medical patients, 17.6% (p = 0.039). This 3-year figure represents a 65% reduction in mortality with surgery. Survival was significantly better for surgical patients whose ejection fractions ranged from 0.30 to 0.49 (p = 0.05). Survival of patients whose ejection fractions were greater than 0.69 was better with medical treatment (p = 0.049). Thus, surgery appears to be the treatment of choice for patients with unstable angina pectoris and abnormal left ventricular function.

PURPOSE OF THE STUDY: The CONNECT intervention is designed to improve staff connections, communication, and use of multiple perspectives for problem solving. This analysis compared staff descriptions of the learning climate, use of social constructivist learning processes, and outcomes in nursing facilities receiving CONNECT with facilities receiving a falls education program alone. DESIGN AND METHODS: Qualitative evaluation of a randomized controlled trial was done using a focus group design. Facilities (n = 8) were randomized to a falls education program alone (control) or CONNECT followed by FALLS (intervention). A total of 77 staff participated in 16 focus groups using a structured interview protocol. Transcripts were analyzed using framework analysis, and summaries for each domain were compared between intervention and control facilities. RESULTS: Notable differences in descriptions of the learning climate included greater learner empowerment, appreciation of the role of all disciplines, and seeking diverse viewpoints in the intervention group. Greater use of social constructivist learning processes was evidenced by the intervention group as they described greater identification of communication weaknesses, improvement in communication frequency and quality, and use of sense-making by seeking out multiple perspectives to better understand and act on information. Intervention group participants reported outcomes including more creative fall prevention plans, a more respectful work environment, and improved relationships with coworkers. No substantial difference between groups was identified in safety culture, shared responsibility, and self-reported knowledge about falls. IMPLICATIONS: CONNECT appears to enhance the use of social constructivist learning processes among nursing home staff. The impact of CONNECT on clinical outcomes requires further study.

BACKGROUND Recurrent respiratory papillomatosis (RRP), caused by human papillomavirus (HPV), is the most common benign neoplasm of the larynx and central airways. RRP has a significant impact on quality life and high annual costs to healthcare. Currently, there is no cure for RRP, leading to repeated debulking operations for symptomatic palliation. Various local adjuvant therapies have also been studied with mixed efficacy. HPV oncogene products increase expression of vascular endothelial growth factor (VEGF) providing a potential target for treatment of RRP. Bevacizumab, a recombinant monoclonal antibody that inhibits VEGF, has shown efficacy in patients with localized disease. CASE REPORT We present two cases of extensive airway and parenchymal RRP successfully managed with systemically administered bevacizumab, a recombinant monoclonal antibody that inhibits VEGF. CONCLUSIONS Bevacizumab has shown efficacy in patients with localized disease, but here we illustrate the potential of bevacizumab for patients with extensive parenchymal burden as well as provide a brief review of the literature.

2022· Annals of Internal Medicine31doi:10.7326/m22-1503

BACKGROUND: Ensovibep (MP0420) is a designed ankyrin repeat protein, a novel class of engineered proteins, under investigation as a treatment of SARS-CoV-2 infection. OBJECTIVE: To investigate if ensovibep, in addition to remdesivir and other standard care, improves clinical outcomes among patients hospitalized with COVID-19 compared with standard care alone. DESIGN: Double-blind, randomized, placebo-controlled, clinical trial. (ClinicalTrials.gov: NCT04501978). SETTING: Multinational, multicenter trial. PARTICIPANTS: Adults hospitalized with COVID-19. INTERVENTION: Intravenous ensovibep, 600 mg, or placebo. MEASUREMENTS: Ensovibep was assessed for early futility on the basis of pulmonary ordinal scores at day 5. The primary outcome was time to sustained recovery through day 90, defined as 14 consecutive days at home or place of usual residence after hospital discharge. A composite safety outcome that included death, serious adverse events, end-organ disease, and serious infections was assessed through day 90. RESULTS: = 0.68; OR > 1 would favor ensovibep). The 90-day cumulative incidence of sustained recovery was 82% for ensovibep and 80% for placebo (subhazard ratio [sHR], 1.06 [CI, 0.88 to 1.28]; sHR > 1 would favor ensovibep). The primary composite safety outcome at day 90 occurred in 78 ensovibep participants (32%) and 70 placebo participants (29%) (HR, 1.07 [CI, 0.77 to 1.47]; HR < 1 would favor ensovibep). LIMITATION: The trial was prematurely stopped because of futility, limiting power for the primary outcome. CONCLUSION: Compared with placebo, ensovibep did not improve clinical outcomes for hospitalized participants with COVID-19 receiving standard care, including remdesivir; no safety concerns were identified. PRIMARY FUNDING SOURCE: National Institutes of Health.

Aqueous amine solutions are benchmark solvents for CO2 capture and their operational drawbacks are well-known. In order to overcome these problems, the support of amines on solid materials appears as an option for CO2 capture. Cellulose is a versatile and low-cost material that can be used as a support. This study reports chemical modification of cellulose fibers extracted from rice husk with different amines and their potential for CO2 capture. The obtained compounds were characterized by different techniques. The CO2 sorption capacity was gravimetrically assessed in a Magnetic Suspension Balance. Quantum mechanical simulations and experimental results revealed that -NH- and -NH2 represent major working sites of the employed compounds. The best result for CO2 sorption was attained for the amine-modified cellulose CL-D-400 with a sorption capacity of 409 µmol CO2/g at 1 bar and 1091 µmol CO2/g at 10 bar with amine concentrations as low as 2 × 10- 6 mol/mg.

Involving Users in the Implementation of an Imaging Order Entry System
David M. Schuster
2003· Journal of the American Medical Informatics Association28doi:10.1197/jamia.m1208

Physician order entry is a powerful function of a computerized hospital information system. Although designed to be clinician-driven, the imaging section of the order entry system may not be designed optimally to engage the clinician with imaging procedures logically organized for the clinician's typical work patterns. There also may be resistance among overburdened clinicians in having to take the time to learn a new computer system and to assume "clerk's duties" of entering imaging orders. A potential means to address clinician opposition is to cooperatively engage each clinical service in the design of an imaging order entry system with customized menus for each service. This article reports a step-by-step process for the implementation of an imaging order entry system with specialized menus for an orthopedic service. This implementation process includes (1) identification of key personnel, (2) familiarization with the system, (3) discussion and dialogue between key personnel, (4) addressing specific problems, (5) education and orientation of the target group, (6) initial implementation, (7) feedback and improvement, (8) demonstration project (time study) to foster acceptance, and (9) ongoing enhancement.

AIM: The aim of this review is to synthesize the current body of knowledge concerning transitional care for patients 65 years of age and older moving from the acute care setting to home. BACKGROUND: Transitional care is a timely topic as hospital days of care decrease whereas patient needs grow more complex as a result of aging populations. EVALUATION: This review considers evidence-based research as well as reports, case studies and literature reviews related to transitional care. International articles are included. KEY ISSUES: The authors explore transitional care through the lens of wicked problems; problems that appear seemingly intractable and are characterized by inter-related dilemmas, contradictory agendas, and multi-layered societal, economic and political influences. Outcome measures of success, barriers to achieving successful transitional care and effectiveness of interventions are investigated. CONCLUSIONS: While the literature offers specific strategies that positively affect transitional care, there are few strategies that do not negatively affect an alternate agenda. Conscientious leaders should consider transitional care in the context of its wicked nature in order to achieve optimal patient care. IMPLICATIONS: Stakeholders include: hospital administrators, nurse leaders, direct-care nurses, acute care and primary care clinicians, patients, caregivers, community agencies, health sciences educators and insurers.

We aimed to determine the diagnostic yield and accuracy of coronary CT angiography (CCTA) in patients referred for invasive coronary angiography (ICA) based on clinical concern for coronary artery disease (CAD) and an abnormal nuclear stress myocardial perfusion imaging (MPI) study. We enrolled 100 patients (84 male, mean age 59.6 ± 8.9 years) with an abnormal MPI study and subsequent referral for ICA. Each patient underwent CCTA prior to ICA. We analyzed the prevalence of potentially obstructive CAD (≥50% stenosis) on CCTA and calculated the diagnostic accuracy of ≥50% stenosis on CCTA for the detection of clinically significant CAD on ICA (defined as any ≥70% stenosis or ≥50% left main stenosis). On CCTA, 54 patients had at least one ≥50% stenosis. With ICA, 45 patients demonstrated clinically significant CAD. A positive CCTA had 100% sensitivity and 84% specificity with a 100% negative predictive value and 83% positive predictive value for clinically significant CAD on a per patient basis in MPI positive symptomatic patients. In conclusion, almost half (48%) of patients with suspected CAD and an abnormal MPI study demonstrate no obstructive CAD on CCTA.

Globalization of Healthcare

Globalization-the increasing transnational circulation of money, goods, people, ideas, and information worldwide-is generally recognized as one of the most powerful forces shaping our current and future history. How is it affecting healthcare, and in that context, what is the purpose and significance of Global Advances in Health and Medicine (GAHM), publisher of this journal? Our goal is not homogenization but rather to provide an opportunity for integration, convergence, and collaboration across cultures. By respecting and conserving the richness and diversity of each new medicine, we embrace globalization. Globalization is of course not new; it began in the Renaissance and particularly with the 15th- and 16th-century voyages of exploration by Columbus, Magellan, and others. Since the beginning of time, there have been interactions and exchanges among different peoples and cultures. However, the current magnitude of globalization is unprecedented and yet still expanding rapidly.

IMPORTANCE: Transit time flow (TTF) probes may be useful for predicting long-term graft patency and assessing grafts intraoperatively in patients undergoing coronary artery bypass grafting (CABG); however, studies of TTF probe use are limited. OBJECTIVE: To examine 1-year graft patency and intraoperative revision rates in patients undergoing CABG based on intraoperative TTF assessment. DESIGN, SETTING, AND PARTICIPANTS: Retrospective analysis of a multicenter randomized clinical trial conducted at 18 Veterans Affairs hospitals using the Randomized On/Off Bypass (ROOBY) Trial data set. Of the original 2203 patients undergoing CABG surgery with or without cardiopulmonary bypass from February 1, 2002, through May 31, 2008, we studied a subset of 1607 who underwent TTF probe analysis of 1 or more grafts during surgery. EXPOSURES: Use of TTF probes to assess graft flow and pulsatility index (PI) values. The decision to revise a graft was based on the judgment of the attending surgeon. MAIN OUTCOMES AND MEASURES: Rates of 1-year FitzGibbon grade A patency and intraoperative revision were compared based on TTF measurements (<20 [low flow] vs ≥20 mL/min [normal flow]) and PI values (<3, 3-5, and >5). RESULTS: We measured TTF and/or PI in 2738 grafts, and 1-year patency was determined in 1710 (62.5%) of these grafts. FitzGibbon grade A patency occurred significantly less often in grafts with a TTF with low flow (259 of 363 [71.3%]) than in those with normal flow (1174 of 1347 [87.2%]; P < .01). FitzGibbon grade A patency was also inversely correlated with increasing PI values, as found in 936 of 1093 grafts (85.6%) with a PI less than 3, 136 of 182 grafts (74.7%) with a PI of 3 to 5, and 91 of 134 grafts (67.9%) with a PI greater than 5 (P ≤ .01). Intraoperative graft revision was more frequent in grafts with low flow (44 of 568 [7.7%]) than in those with normal flow (8 of 2170 [0.4%]; P < .01). Graft revision was also more frequent as PI increased (12 of 1827 [0.7%] with a PI <3, 9 of 307 [2.9%] with a PI 3-5, and 9 of 155 [5.8%] with a PI >5; P < .01). CONCLUSIONS AND RELEVANCE: Intraoperative TTF probe data may be helpful in predicting long-term patency and in the decision of whether to revise a questionable graft for patients undergoing CABG surgery.

Audiologists' role in providing care for tinnitus typically includes conducting an audiologic evaluation, fitting hearing aids when appropriate, assessing the impact of tinnitus, and facilitating use of sound to improve quality of life with tinnitus when appropriate. Cognitive behavioral therapy (CBT) is consistently judged by systematic reviews as having the strongest evidence relative to other therapies for improving quality of life with tinnitus. Because audiologists are already playing an active role in providing care for tinnitus, and the relative paucity of behavioral health providers who are experienced in implementing CBT for tinnitus, a logical question is whether audiologists can provide CBT and whether it is within their scope of practice. In this article, we present both sides of the argument as to whether audiologists can provide CBT and we make recommendations for appropriate administration of CBT for tinnitus management.
