RESUMO
STUDY OBJECTIVES: Insomnia is a common medical complaint. Current pharmacologic treatments have modest efficacy and numerous side effects. Baclofen is a gamma-aminobutyric acid (GABA)b receptor agonist used to treat spasticity in various medical conditions. Several studies noted that baclofen, when used to treat sleep related disorders, resulted in improvement in sleep parameters. Measures of insomnia, however, were not assessed in those studies. To date, baclofen has not been assessed for efficacy in the treatment of insomnia. METHODS: We randomized 20 healthy subjects to baclofen or placebo in a cross over design. All subjects underwent two polysomnograms (PSG) assessing sleep parameters. Baclofen or placebo was given 90 min prior to lights out in random order for each subject. Lights out occurred two hours earlier than the subject's median habitual bedtime. RESULTS: Baclofen resulted in significantly less objective wake after sleep onset and stage 1 sleep, and significantly increased total sleep time (TST), sleep efficiency, and stage 3/4 sleep. There was no effect on sleep onset latency (SOL). Self-report variables indicated significantly less subjective awakenings from sleep and increased subjective sleep quality. There was no effect on subjective TST or subjective SOL. CONCLUSIONS: This study showed that baclofen was superior to placebo with regard to several objective and subjective measures used to assess sleep quality. These data support the notion that baclofen shows promise as an effective hypnotic drug.

Chronic obstructive pulmonary disease (COPD) represents an important global public health concern. Malnutrition is common in patients with COPD and often leads to worse outcomes for these patients. Recognition of overall nutrition status for patients with COPD is an important aspect of their care and treatment. Several methods have been studied that move beyond the standard/frequent use of body mass index alone. The purpose of this review is to summarize the current evidence for other tools to evaluate nutrition status in patients with COPD and highlight patients who may benefit from nutrition interventions.

RESUMO
OBJECTIVES: Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is the primary method for the diagnosis and staging of lung cancer. The purpose of this study was to assess the yield of EBUS-TBNA in the subtyping and genotyping of lung adenocarcinoma. METHODS: Sixty-nine patients at Indiana University Hospital and Sidney and Lois Eskenazi Hospital with possible or confirmed lung adenocarcinoma underwent EBUS-TBNA using a 21-gauge Olympus needle without suction. Samples were sent for molecular testing after rapid onsite specimen evaluation. A total of 6 to 10 passes were placed in a cell block. RESULTS: Sixty-nine samples from patients with non-small-cell lung cancer were sent for molecular testing for epidermal growth factor receptor. Results were obtained in all of the patients. Mutations were found in three patients (4.3%). Fifty-eight samples were sent for V-Ki-ras2 Kirsten rat sarcoma viral oncogene homolog (100% yield), 10 of which had mutations (17.2%). Fifty-one samples were sent for proto-oncogene tyrosine-protein kinase ROS testing (1 [7.8%] mutant). Tissue samples were inadequate in three patients (94.1% yield). Sixty-three samples were sent for anaplastic lymphoma receptor tyrosine kinase testing (3 [4.8%] mutant, 6 [9.5%] inadequate, 90.5% yield). CONCLUSIONS: EBUS-TBNA with a 21-gauge needle is appropriate for the analysis of multiple mutations and the genotyping of lung adenocarcinoma.

OBJECTIVE: To report the 15-year trend in ophthalmic presentations to the emergency department (ED) at the only medical center in Lebanon that provides 24-hour ophthalmologic care. METHODS: Retrospective review of 1967 patients presenting to the ED with eye-related complaints between September 1997 and August 1998 and between September 2012 and August 2013. Diagnoses were classified into 4 categories according to the International Society of Ocular Trauma and include penetrating eye injuries, nonpenetrating eye trauma, nontraumatic ophthalmic emergencies, and nontraumatic, nonurgent ophthalmic conditions. RESULTS: One thousand sixty eye-related presentations out of 39,158 total ED visits (2.71%) presented in 1997 compared to 907 out of 46,363 in 2012 (1.96%). Penetrating and nonpenetrating eye emergencies decreased between 1997 and 2012 (7.17% to 4.19%, p = 0.003 and 52.64% to 29.00%, p < 0.001, resp.) while nonurgent cases increased from 30.19% to 53.47% (p < 0.001). 57% of patients were covered by third-party guarantors in 1997 versus 73% in 2012. CONCLUSION: Our results demonstrate a significant increase in nonurgent cases in parallel with the proportion of third-party payers, an issue to be addressed by public health policies and proper resource allocation. A detailed nationwide review is needed to make solid recommendations for the management of ophthalmologic presentations in the ED.
RESUMO
PURPOSE: The authors hypothesize patient facial affect may influence clinician pretest probability (PTP) estimate of cardiopulmonary emergency (CPE) and desire to order a computerized tomographic pulmonary angiogram (CTPA). METHOD: This prospective study was conducted at three Indiana University-affiliated hospitals in two parts: collecting videos of patients undergoing CTPA for suspected acute pulmonary embolism watching a humorous video (August 2014-April 2015) and presenting the medical histories and videos to clinicians to determine the impact of patient facial affect on physicians' PTP estimate of CPE and desire to order a CTPA (June-November 2015). Patient outcomes were adjudicated as CPE+ or CPE- by three independent reviewers. Physicians completed a standardized test of facial affect recognition, read standardized medical histories, then viewed videos of the patients' faces. Clinicians marked their PTP estimate of CPE and desire for a CTPA before and after seeing the video on a visual analog scale (VAS). RESULTS: Fifty physicians completed all 73 videos. Seeing the patient's face produced a > 10% absolute change in PTP estimate of CPE in 1,204/3,650 (33%) cases and desire for a CTPA in 1,095/3,650 (30%) cases. The mean area under the receiver operating characteristic curve for CPE estimate was 0.55 ± 0.15, and the change in CPE VAS was negatively correlated with physicians' standardized test scores (r = -0.23). CONCLUSIONS: Clinicians may use patients' faces to make clinically important inferences about presence of serious illness and need for diagnostic testing. However, these inferences may fail to align with actual patient outcomes.

OBJECTIVE: In our academic intensive care unit (ICU), there is excess ordering of routine laboratory tests. This is partially due to a lack of transparency of laboratory-processing costs and to the admission order plans that favor daily laboratory test orders. We hypothesized that a program that involves physician and staff education and alters the current ICU order sets will lead to a sustained decrease in routine laboratory test ordering. DESIGN: Prospective cohort study. SETTING: Academic closed medical ICU (MICU). PATIENTS: All patients admitted to the MICU. METHODS: We consistently educated residents, faculty, and staff about laboratory test costs. We removed the daily laboratory test option from the admission order sets and asked residents to order needed laboratory test results every day. We only allowed the G3+I-STAT (arterial blood gas only) cartridges in the MICU in hopes of decreasing duplicative laboratory test results. We added laboratory review to the daily rounding checklist. MEASUREMENT AND MAIN RESULTS: Total number of laboratory tests per patient-day decreased from 39.43 to an average of 26.74 ( P <.001) over a 9-month period. The number of iSTAT laboratory tests per patient-day decreased from 7.37 to an average of 1.16 ( P < .001) over the same time period. The number of iSTAT/central laboratory processing duplicative laboratory tests per patient-day decreased from 0.17 to an average of 0.01 ( P < .001). The percentage of patients who have daily laboratory test orders decreased from 100% to an average of 11.94% ( P <. 001). US$123 436 in direct savings and US$258 035 dollars in indirect savings could be achieved with these trends. Intensive care unit morbidity and mortality were not impacted. CONCLUSION: A simple technique of resident, nursing, and ancillary staff education, combined with alterations in order sets using electronic medical records, can lead to a sustained reduction in laboratory test utilization over time and to significant cost savings without affecting patient safety.

OBJECTIVE: To estimate the 5-year incidence of progression rate and regression rate and risk factors for diabetic retinopathy (DR) in a cohort of Lebanese patients with type II diabetes. METHODS: We followed a cohort of 462 Lebanese patients with type II diabetes for over 5 years at the American University of Beirut Medical Center. Patients underwent yearly complete ophthalmic evaluation and fundus photographs and were assessed for the incidence, stage, and evolution of DR using modified Airlie House classification. RESULTS: Among the 462 patients, 281 had no DR at baseline. The 5-year cumulative incidence of any DR was 10% (95% CI: 6-13), and only baseline microalbuminuria correlated with the development of DR (OR = 10.53, 95% CI: 4.39-25.23, p < 0.0001). Among the 181 patients with baseline DR, the worsening and regression rates of DR were 31.5% (95% CI: 25-38) and 9% (95% CI: 5-13), respectively. Microalbuminuria also approached statistical significance as a risk factor for DR worsening (OR = 1.89, 95% CI: 0.97-3.70, p = 0.06). CONCLUSION: The 5-year incidence of DR in this hospital-based cohort is relatively low. Microalbuminuria was independently associated with the incidence and progression of the disease. We recommend to screen patients with type II diabetes for microalbuminuria as prognostic for the development and worsening of DR.
