Over the last few years, there has been a renewed interest in patients with characteristics of both asthma and COPD. Although the precise definition of asthma-COPD overlap (ACO) is still controversial, patients with overlapping features are frequently encountered in clinical practice, and may indeed have worse clinical outcomes and increased health-care utilization than those with asthma or COPD. Therefore, there is a critical need to set a framework for the therapeutic approach of such patients. There are key distinctions in the therapy between asthma and COPD, particularly regarding the initial choice of therapy. However, there is considerable overlap in the use of existing medications for both diseases. Furthermore, novel therapies approved for asthma, such as monoclonal antibodies, may have a role in patients with COPD and ACO. The use of biomarkers, such as peripheral blood eosinophils, exhaled nitric oxide, and serum IgE, may help in selecting appropriate therapies for ACO. In this review, we provide an overview of available treatments for both asthma and COPD and explore their potential role in the treatment of patients with ACO.

Background: Inhaled medications form the foundation of pharmacologic treatment for chronic obstructive pulmonary disease (COPD).The Delivery Makes a Difference (DMaD) project was conducted to better understand health care provider (HCP) and patient perspectives about the role of inhalation delivery devices in COPD, and to examine the nature of educational efforts between HCPs and patients on proper device technique. Methods: Data were derived from 2 original quantitative, web-based, descriptive, cross-sectional surveys distributed to HCPs who manage COPD (n=513) and patients with COPD (n=499) in the United States. Descriptive statistics were used to assess data across important demographic variables. Inferential statistics were used to assess differences in attitudinal, descriptive, and behavioral measures that were cross-tabulated with demographic data. Results: When prescribing medication for newly diagnosed patients with stable or unstable COPD, only 37% of HCPs considered type of device to be highly important, with only 45% of HCPs assessing device technique in every newly diagnosed patient. Patients with COPD were also relatively unconcerned with proper device technique (64% never concerned), regardless of their COPD severity. Although patients did not identify education as a significant impediment to proper device use, they reported inconsistent educational experiences. Conclusions: We found that HCPs and patients prioritize medication over device when selecting treatments, showing limited concerns about proper device use. These results highlight the need to coordinate professional education with patient-directed educational efforts to further promote proper device selection and use in COPD management.
RESUMEN
PURPOSE: A case series of icatibant use in intubated patients with angiotensin-converting enzyme inhibitor- (ACEI-) induced angioedema is presented along with a relevant literature review and recommendations for utilization. SUMMARY: Three intubated patients admitted to the intensive care unit for ACEI-induced angioedema were treated with icatibant. A literature search identified one controlled study and four case reports describing the use of icatibant in intubated ACEI-induced angioedema patients. CONCLUSION: Icatibant administration in intubated patients may be beneficial in decreasing time to extubation and length of intensive care unit stay. In the three cases described, icatibant administration did not appear to elicit a response in intubated patients, which has been described in previous case reports. For clinicians considering icatibant in the treatment of ACEI-induced angioedema, earlier administration upon arrival to the ED or immediately upon arriving to the intensive care unit is strongly advised. The suggested benefit of icatibant in intubated ACEI-induced angioedema patients should be verified by randomized clinical trials and cost-benefit analyses should be performed at individual institutions.
RESUMEN
BACKGROUND: Physical and psychological symptoms are the hallmark of patients' subjective perception of their illness. The purpose of this analysis was to determine if patients with COPD have distinctive symptom profiles and to examine the association of symptom profiles with systemic biomarkers of inflammation. METHODS: We conducted latent class analyses of three physical (dyspnea, fatigue, and pain) and two psychological symptoms (depression and anxiety) in 302 patients with moderate to severe COPD using baseline data from a longitudinal observational study of depression in COPD. Systemic inflammatory markers included IL1, IL8, IL10, IL12, IL13, INF, GM-CSF, TNF-α (levels >75thcentile was considered high); and CRP (levels >3 mg/L was considered high). Multinominal logistic regression models were used to examine the association between symptom classes and inflammation while adjusting for key socio-demographic and disease characteristics. RESULTS: We found that a 4-class model best fit the data: 1) low physical and psychological symptoms (26%, Low-Phys/Low-Psych), 2) low physical but moderate psychological symptoms (18%, Low-Phys/Mod Psych), 3) high physical but moderate psychological symptoms (25%, High-Phys/Mod Psych), and 4) high physical and psychological symptoms (30%, High-Phys/High Psych). Unadjusted analyses showed associations between symptom class with high levels of IL7, IL-8 (p ≤ .10) and CRP (p < .01). In the adjusted model, those with a high CRP level were less likely to be in the High-Phys/Mod-Psych class compared to the Low-Phys/Low-Psych (OR: 0.41, 95%CI 0.19, 0.90) and Low-Phys/Mod-Psych classes (OR: 0.35, 95%CI 0.16, 0.78); elevated CRP was associated with in increased odds of being in the High-Phys/High-Psych compared to the High-Phys/Mod-Psych class (OR: 2.22, 95%CI 1.08, 4.58). Younger age, having at least a college education, oxygen use and depression history were more prominent predictors of membership in the higher symptom classes. CONCLUSIONS: Patients with COPD can be classified into four distinct symptom classes based on five commonly co-occurring physical and psychological symptoms. Systemic biomarkers of inflammation were not associated with symptom class. Additional work to test the reliability of these symptom classes, their biological drivers and their validity for prognostication and tailoring therapy in larger and more diverse samples is needed.

PURPOSE: The purpose of the study is to evaluate the frequency and barriers to use of ultrasound guidance for central venous catheter (CVC) insertion by physicians specializing in critical care and hospital medicine. MATERIALS AND METHODS: A national cross-sectional electronic survey of intensivists and hospitalists was administered from November 2014 to January 2015. RESULTS: The survey response rate was 5.9% (1013/17 233). Moderate to very frequent use of ultrasound guidance varied by site: internal jugular vein (80%), subclavian vein (31%), and femoral vein (45%). Nearly all physicians (99%) who insert internal jugular CVCs daily use ultrasound guidance, whereas only 46% of physicians who insert subclavian CVCs daily use ultrasound guidance. Use of real-time ultrasound guidance varied by insertion site: internal jugular vein (73%), subclavian vein (28%), and femoral vein (42%). Most physicians (59%) reported not being comfortable with real-time needle tracking at the subclavian site. The most frequently reported barriers to use of ultrasound guidance were (1) limited availability of ultrasound equipment (28%), (2) perception of increased total procedure time (22%), and (3) concern for loss of landmark skills (13%). CONCLUSIONS: Most intensivists routinely use ultrasound guidance to insert internal jugular CVCs but not subclavian CVCs. The most commonly reported barrier to ultrasound use was limited access to an ultrasound machine.

BACKGROUND: Neurocognitive impairment has been described in COPD patients, but little is known about its relationship with physical functioning and health-related quality of life (HRQL) in this chronically ill patient group. METHODS: 301 stable COPD patients completed the Trail Making Test (TMT-A: psychomotor speed and TMT-B: executive control); 198 patients completed the Memory Impairment Screen (MIS). Standardization of TMT-A and TMT-B scores to a normative population yielded classifications of normal, borderline, or impaired cognitive status. Using multivariable regression, we examined the relationship between the TMT-A, TMT-B, and MIS with physical functioning (physical activity, 6-min walk test, and grip strength) and health-related quality of life (HRQL) measured with the Chronic Respiratory Questionnaire and the SF-36. RESULTS: Nearly 30% of patients had either borderline or impaired cognition on the TMT-A or TMT-B. Adjusted models indicated that those with either borderline or impaired cognitive functioning had weaker grip strength (TMT-A borderline: ß = -2.9, P < 0.05; TMT-B borderline: ß = -3.0, P < 0.05; TMT-B impaired: ß = -2.5, P < 0.05) and lower scores on the mental health component summary score (MCS-SF-36 HRQOL) measure (TMT-A impaired: ß = -4.7, P < 0.01). No adjusted significant associations were found for other physical functioning measures or the other HRQL measures. Impaired memory showed a significant association only with the MCS scale. CONCLUSIONS: Cognitive function was not associated with most standard indicators of physical function or most measures of HRQL in COPD patients. Both TMT-A and TMT-B were associated with weaker grip strength, and the TMT-A and MIS with poorer mental health.

Chronic obstructive pulmonary disease (COPD) is associated with significant morbidity, places substantial time and cost burden on the health care system, and is now the third leading cause of death in the US. Many interventions are available to appropriately manage patients with COPD; however, fully implementing these strategies to help improve outcomes may be difficult. Collaboration between an interprofessional team of health care professionals (which includes physicians, nurses, respiratory therapists, physical therapists, dietitians, pharmacists, and many others) and COPD patients and caregivers is necessary to optimally manage these patients and to truly impact outcomes in this devastating disease. Prescribing evidence-based non-pharmacological and pharmacological therapies is an important start, but a true team-based approach is critical to successfully implement comprehensive care in patients with COPD. The goal of this review is to employ a case-based approach to provide practical information regarding the roles of the interprofessional team in implementing strategies to optimally manage COPD patients.

PURPOSE: The purpose of this study was to examine the prevalence and correlates of suicidal ideation (SI) in patients with stable moderate to very severe chronic obstructive pulmonary disease (COPD). PATIENTS AND METHODS: We conducted an exploratory mixed methods analysis of data from participants in a longitudinal observational study of depression in COPD. We measured depression with the Patient Health Questionnaire-9 (PHQ-9), which includes an item on SI. We compared participants with and without SI in relation to sociodemographics, symptoms, anxiety, and healthcare resource use with independent t-tests and chi-square tests. Content analysis was performed on qualitative data gathered during a structured SI safety assessment. RESULTS: Of 202 participants, 121 (60%) had depressive symptoms (PHQ ≥6); 51 (25%) had a PHQ-9 ≥10, indicating a high likelihood of current major depression; and 22 (11%) reported SI. Compared to the 99 depressed participants without SI, those with SI were more likely to be female (59% vs 27%, P=0.004); had worse dyspnea (P=0.009), depression (P<0.001), and anxiety (P=0.003); and were also more likely to have received treatment for depression and/or anxiety (82% vs 40%, P<0.001) and more hospitalizations for COPD exacerbations (P=0.03) but had similar levels of airflow obstruction and functioning than participants without SI. Themes from the qualitative analysis among those with SI included current or prior adverse life situations, untreated or partially treated complex depression, loss of a key relationship, experience of illness and disability, and poor communication with providers. CONCLUSION: Our findings suggest that current SI is common in COPD, may occur disproportionately in women, can persist despite mental health treatment, and has complex relationships with both health and life events. Adequate management of SI in COPD may therefore require tailored, comprehensive treatment approaches that integrate medical and mental health objectives.

BACKGROUND: Physical activity (PA) has been found to be an excellent predictor of mortality beyond traditional measures in COPD. We aimed to determine the association between depression and anxiety with accelerometry-based PA in patients with COPD. METHODS: We performed a cross-sectional analysis of baseline data from 148 stable patients with COPD enrolled in an ongoing, longitudinal, observational study. We measured PA (total daily step count) with a Stepwatch Activity Monitor over 7 days, depression and anxiety with the Hospital Anxiety and Depression Scales (HADSs), dyspnea with the Shortness of Breath Questionnaire, and functional capacity with the 6-min walk test. RESULTS: Increased anxiety was associated with higher levels of PA such that for every one-point increase in the HADS-Anxiety score there was a corresponding increase of 288 step counts per day (ß=288 steps, P<.001), after adjusting for all other variables. Higher levels of depressive symptoms were associated with lower PA (ß=-176 steps, P=.02) only when anxiety was in the model. The interaction term for anxiety and depression approached significance (ß=26, P=.10), suggesting that higher levels of anxiety mitigate the negative effects of depression on PA. CONCLUSIONS: The increased PA associated with anxiety in COPD is, to our knowledge, a novel finding. However, it is unclear whether anxious patients with COPD are more restless, and use increased psychomotor activity as a coping mechanism, or whether those with COPD who push themselves to be more physically active experience more anxiety symptoms. Future studies should evaluate for anxiety and PA to better inform how to improve clinical outcomes. TRIAL REGISTRY: Clinicaltrials.gov; No.: NCT01074515; URL: www.clinicaltrials.gov.

Asthma is an inflammatory lung condition that is the most common chronic disease affecting pregnancy. The changes in pulmonary physiology during pregnancy include increased minute ventilation, decreased functional residual capacity, increased mucus production, and airway mucosa hyperemia and edema. Pregnancy is also associated with a physiological suppression of the immune system. Many studies have described the heterogeneous immune system response in women with asthma during pregnancy, which partly explains why asthma has been shown to worsen, improve, or remain stable in equal proportions of women during pregnancy. Asthma may be associated with poor maternal and fetal outcomes. However, better maternal and fetal outcomes are observed with better asthma control. Asthma controller medications are generally thought to be safe during pregnancy, but limited data are available for some of the medicines. Newer medications like omalizumab open avenues for the treatment of asthma, but also pose a challenge, as there is limited experience with their use. Therefore, a multidisciplinary approach, including obstetricians, asthma specialists, and pediatricians should collaborate with the patient to carefully weigh the risks and benefits to determine an optimal management plan for each individual patient. The aim of this review article is to summarize the most recent literature about the immunological changes that occur during pregnancy, physiological and clinical implications of asthma on pregnancy, and asthma management and medication use in pregnant women.

OBJECTIVES: To describe the development and implementation process and assess the effect on self-reported clinical practice changes of a multidisciplinary, collaborative, interactive continuing medical education (CME)/continuing education (CE) program on chronic obstructive pulmonary disease (COPD). METHODS: Multidisciplinary subject matter experts and education specialists used a systematic instructional design approach and collaborated with the American College of Chest Physicians and American Academy of Nurse Practitioners to develop, deliver, and reproduce a 1-day interactive COPD CME/CE program for 351 primary care clinicians in 20 US cities from September 23, 2009, through November 13, 2010. RESULTS: We recorded responses to demographic, self-confidence, and knowledge/comprehension questions by using an audience response system. Before the program, 173 of 320 participants (54.1%) had never used the Global Initiative for Chronic Obstructive Lung Disease recommendations for COPD. After the program, clinician self-confidence improved in all areas measured. In addition, participant knowledge and comprehension significantly improved (mean score, 77.1%-94.7%; P<.001). We implemented the commitment-to-change strategy in courses 6 through 20. A total of 271 of 313 participants (86.6%) completed 971 commitment-to-change statements, and 132 of 271 (48.7%) completed the follow-up survey. Of the follow-up survey respondents, 92 of 132 (69.7%) reported completely implementing at least one clinical practice change, and only 8 of 132 (6.1%) reported inability to make any clinical practice change after the program. CONCLUSION: A carefully designed, interactive, flexible, dynamic, and reproducible COPD CME/CE program tailored to clinicians' needs that involves diverse instructional strategies and media can have short-term and long-term improvements in clinician self-confidence, knowledge/comprehension, and clinical practice.

BACKGROUND: Improving a patient's ability to self-monitor and manage changes in chronic obstructive pulmonary disease (COPD) symptoms may improve outcomes. OBJECTIVE: To determine the efficacy of a comprehensive care management program (CCMP) in reducing the risk for COPD hospitalization. DESIGN: A randomized, controlled trial comparing CCMP with guideline-based usual care. (ClinicalTrials.gov registration number: NCT00395083) SETTING: 20 Veterans Affairs hospital-based outpatient clinics. PARTICIPANTS: Patients hospitalized for COPD in the past year. INTERVENTION: The CCMP included COPD education during 4 individual sessions and 1 group session, an action plan for identification and treatment of exacerbations, and scheduled proactive telephone calls for case management. Patients in both the intervention and usual care groups received a COPD informational booklet; their primary care providers received a copy of COPD guidelines and were advised to manage their patients according to these guidelines. Patients were randomly assigned, stratifying by site based on random, permuted blocks of variable size. MEASUREMENTS: The primary outcome was time to first COPD hospitalization. Staff blinded to study group performed telephone-based assessment of COPD exacerbations and hospitalizations, and all hospitalizations were blindly adjudicated. Secondary outcomes included non-COPD health care use, all-cause mortality, health-related quality of life, patient satisfaction, disease knowledge, and self-efficacy. RESULTS: Of the eligible patients, 209 were randomly assigned to the intervention group and 217 to the usual care group. Citing serious safety concerns, the data monitoring committee terminated the intervention before the trial's planned completion after 426 (44%) of the planned total of 960 patients were enrolled. Mean follow-up was 250 days. When the study was stopped, the 1-year cumulative incidence of COPD-related hospitalization was 27% in the intervention group and 24% in the usual care group (hazard ratio, 1.13 [95% CI, 0.70 to 1.80]; P= 0.62). There were 28 deaths from all causes in the intervention group versus 10 in the usual care group (hazard ratio, 3.00 [CI, 1.46 to 6.17]; P= 0.003). Cause could be assigned in 27 (71%) deaths. Deaths due to COPD accounted for the largest difference: 10 in the intervention group versus 3 in the usual care group (hazard ratio, 3.60 [CI, 0.99 to 13.08]; P= 0.053). LIMITATIONS: Available data could not fully explain the excess mortality in the intervention group. Ability to assess the quality of the educational sessions provided by the case managers was limited. CONCLUSION: A CCMP in patients with severe COPD had not decreased COPD-related hospitalizations when the trial was stopped prematurely. The CCMP was associated with unanticipated excess mortality, results that differ markedly from similar previous trials. A data monitoring committee should be considered in the design of clinical trials involving behavioral interventions.

Chronic obstructive pulmonary disease (COPD) remains the fourth leading cause of death, is associated with significant morbidity and places a substantial time and cost burden on the health care system. Unfortunately, treatment for COPD remains underutilized and continues to focus on the acute care of complications. The chronic care model (CCM) shifts this focus from the acute management of symptoms and complications to the prevention and optimal management of the chronic disease. This model utilizes resources from the community and the health care system and emphasizes self-management, provides comprehensive clinic support, and implements evidence-based guidelines and technology into clinical practice to ensure delivery of the highest quality of care. The goal of this review is to use a case-based approach to provide practical information about how integrated care using the CCM can be applied to the clinical care of a complex patient with COPD, shifting the management goals for COPD from reactive to proactive and ultimately improving outcomes.
RESUMEN
INTRODUCTION: In chronic diseases such as chronic obstructive pulmonary disease (COPD), patients may not perceive all of the benefits of drug therapy until withdrawal. Thus, we evaluated the effect of tiotropium withdrawal on clinical variables. METHODS: COPD subjects who participated in two identical 1-year, prospective, double-blind, placebo-controlled studies of tiotropium 18 microg once daily who completed a 3-week visit following discontinuation of therapy were included in this analysis. Outcomes measured included dyspnea (transition dyspnea index [TDI]), Peak Expiratory Flow Rate (PEFR), health status (St George's Respiratory Questionnaire [SGRQ]), and rescue beta2-agonist use. RESULTS: Overall, the tiotropium group exhibited significant improvements in clinical parameters at the end of therapy. Of the entire cohort of 921 patients, 713 patients (77%) completed 3-weeks post-withdrawal evaluation. Patients in the tiotropium group had 1.1 unit worsening in TDI, decreased in PEFR, health status and reduced beta(2)-agonist medication following treatment discontinuation, while the placebo group remained relatively stable. CONCLUSIONS: The withdrawal of tiotropium results in worsening of COPD over a three-week interval. There was no evidence of a rebound effect in response to tiotropium withdrawal.

BACKGROUND: Implementation of the chronic care model (CCM) has been shown to be an effective preventative strategy to improve outcomes in diabetes mellitus, depression, and congestive heart failure, but data are lacking regarding the effectiveness of this model in preventing complications in patients with chronic obstructive pulmonary disease. METHODS: We searched the MEDLINE, CINAHL, and Cochrane databases from inception to August 2005 and included English-language articles that enrolled adults with chronic obstructive pulmonary disease and (1) contained intervention(s) with CCM component(s), (2) included a comparison group or measures at 2 points (before/after), and (3) had relevant outcomes. Two reviewers independently extracted data. RESULTS: Symptoms, quality of life, lung function, and functional status were not significantly different between the intervention and control groups. However, pooled relative risks (95% confidence intervals) for emergency/unscheduled visits and hospitalizations for the group that received at least 2 CCM components were 0.58 (0.42-0.79) and 0.78 (0.66-0.94), respectively. The weighted mean difference (95% confidence interval) for hospital stay was -2.51 (-3.40 to -1.61) days shorter for the group that received 2 or more components. There were no significant differences for those receiving only 1 CCM component. CONCLUSIONS: Limited published data exist evaluating the efficacy of CCM components in chronic obstructive pulmonary disease management. However, pooled data demonstrated that patients with chronic obstructive pulmonary disease who received interventions with 2 or more CCM components had lower rates of hospitalizations and emergency/unscheduled visits and a shorter length of stay compared with control groups. The results of this review highlight the need for well-designed trials in this population.

RATIONALE: One of the limitations associated with lung transplantation is the lack of available organs. OBJECTIVE: To determine whether a lung donor-management protocol could increase the number of lungs for transplantation without affecting the survival rates of the recipients. METHODS: We implemented the San Antonio Lung Transplant protocol for managing potential lung donors according to modifications of standard criteria for donor selection and strategies for donor management. We then compared information gathered during a 4-yr period, during which the protocol was used with information gathered during a 4-yr period before protocol implementation. Primary outcome measures were the procurement rate of lungs and the 30-d and 1-yr survival rates of recipients. MAIN RESULTS: We reviewed data from 711 potential lung donors. The mean rate of lung procurement was significantly higher (p < 0.0001) during the protocol period (25.5%) than during the pre-protocol period (11.5%), with an estimated risk ratio of 2.2 in favor of the protocol period. More patients received transplants during the protocol period (n = 121) than during the pre-protocol period (n = 53; p < 0.0001). Of 98 actual lung donors during the protocol period, 53 (54%) had initially been considered poor donors; these donors provided 64 (53%) of the 121 lung transplants. The type of donor was not associated with significant differences in recipients' 30-d and 1-yr survival rates or any clinical measures of adequate graft function. CONCLUSIONS: The protocol was associated with a significant increase in the number of lung donors and transplant procedures without compromising pulmonary function, length of stay, or survival of the recipients.
