Background. Improvement in PFT after bronchodilators is characteristic of obstructive airway diseases such as COPD. However, improvement in patients with restrictive pattern is occasionally seen. We aim to determine the clinical significance of a bronchodilator responsive restrictive defect.Methods. Patients with restrictive spirometry and a bronchodilator study were identified at the University of Oklahoma and Oklahoma City VAMC between September 2003 and December 2009. Restriction was defined as a decreased FVC and FEV1, with normal FEV1/FVC. Responsiveness to bronchodilators was defined as an improvement in FEV1 and/or FVC of at least 12% and 200 mL. Patients with lung volume measurements had their clinical and radiographic records reviewed.Results. Twenty-one patients were included in the study. Most were current or ex-smokers, with most being on bronchodilators. The average FVC and FEV1 were65±11%and62±10%of the predicted, respectively. Most patients (66%) had a normal TLC, averaging90±16%of the predicted. RV, RV/TLC, and the TLC-VA values strongly suggested an obstructive defect.Conclusions. Reversible restrictive pattern on spirometry appears to be a variant of obstructive lung disease in which early airway closure results in air trapping and low FVC. In symptomatic patients, a therapeutic trial of bronchodilators may be beneficial.

The incidence of chronic obstructive pulmonary disease (COPD) in Malaysia appear to be increasing. To date, there are no local studies describing restrictive and obstructive airflow limitation patterns using spirometry. We conducted a crosssectional study to determine the prevalence and predictors of airflow limitation symptoms by screening for COPD symptoms with the COPD Population Screener (COPD-PS) questionnaire and determined the airflow limitation using the new hand-held device, AirSmart®. We recruited 265 subjects. Eleven percent had restrictive pattern and 16% had obstructive pattern. Twenty percent of subjects had COPD-PS score of more than five. In the obstructive pattern group, 74% were active or ex-smokers (p=0.03, p<0.01), whilst those with restrictive pattern were more likely to be heavier with a body mass index (BMI) of more than 23 (OR 2.52, 95% CI: 1.02-5.62) (p<0.01). There was a negative correlation between forced vital capacity and BMI (r=-0.5813, p<0.001). We found a high prevalence restrictive pattern of airflow limitation using the new AirSmart® Spirometer. There appeared to be a large proportion of undiagnosed obstructive airway diseases and higher BMI could be the causes of limitation of airflow in our subjects.

The WxChallenge, a project developed at the University of Oklahoma, brings a state-of-the-art, fun, and exciting forecast contest to participants at colleges and universities across North America. The challenge is to forecast the maximum and minimum temperatures, precipitation, and maximum wind speeds for select locations across the United States over a 24-h prediction period. The WxChallenge is open to all undergraduate and graduate students, as well as higher-education faculty, staff, and alumni. Through the use of World Wide Web interfaces accessible by personal computers, tablet computer, and smartphones, the WxChallenge provides a state-of-the-art portal to aid participants in submitting forecasts and alleviate many of the administrative issues (e.g., tracking and scoring) faced by local managers and professors. Since its inception in 2006, 110 universities have participated in the contest and it has been utilized as part of the curricula for 140 classroom courses at various institutions. The inherently challenging nature of the WxChallenge has encouraged its adoption as an educational tool. As its popularity has grown, professors have seen the utility of the Wx-Challenge as a teaching aid and it has become an instructional resource of many meteorological classes at institutions for higher learning. In addition to evidence of educational impacts, the competition has already begun to leave a cultural and social mark on the meteorological learning experience.

AbstractChronic obstructive airway diseases such as chronic obstructive pulmonary disease (COPD), asthma, rhinitis, and obstructive sleep apnea (OSA) are amongst the most common treatable and preventable chronic conditions with high morbidity burden and mortality risk. We aimed to explore the existence of multimorbidity clusters in patients with such diseases and to estimate their prevalence and impact on mortality. We conducted an observational retrospective study in the EpiChron Cohort (Aragon, Spain), selecting all patients with a diagnosis of allergic rhinitis, asthma, COPD, and/or OSA. The study population was stratified by age (i.e., 15–44, 45–64, and ≥ 65 years) and gender. We performed cluster analysis, including all chronic conditions recorded in primary care electronic health records and hospital discharge reports. More than 75% of the patients had multimorbidity (co-existence of two or more chronic conditions). We identified associations of dermatologic diseases with musculoskeletal disorders and anxiety, cardiometabolic diseases with mental health problems, and substance use disorders with neurologic diseases and neoplasms, amongst others. The number and complexity of the multimorbidity clusters increased with age in both genders. The cluster with the highest likelihood of mortality was identified in men aged 45 to 64 years and included associations between substance use disorder, neurologic conditions, and cancer. Large-scale epidemiological studies like ours could be useful when planning healthcare interventions targeting patients with chronic obstructive airway diseases and multimorbidity.

PurposeFrom the cataloging librarians' point of view, this paper aims to present how technical services, especially the cataloging department, can play important roles in the improvement of user services.Design/methodology/approachThe paper examines the practices of the University of Oklahoma Libraries.FindingsThe paper identifies several aspects in which technical services can enhance the quality of user services, especially in the cataloging department. A library's online catalog becomes the first point of access to the library's information resources. Its quality can be improved and enriched in many ways to raise users’ satisfaction. Aside from the improvement in technical aspects, efforts should also be made to promote collaboration between technical and public services so as to ensure efficient processing of materials and to meet the needs of library users.Originality/valueThe value of the paper is in showing that the quality of an online catalog and the cooperation between public and technical services are two of the key factors in achieving high quality of user services.

Study Design: A retrospective analysis of patients with subcondylar fractures treated via a transmasseteric anteroparotid approach by the Oral and Maxillofacial Department at the University of Oklahoma. Objective: The goal of this study was to evaluate complications, morbidity, and safety with the transmasseteric anteroparotid approach for treatment of subcondylar fractures, and compare it to other findings previously reported in the literature. Methods: A retrospective study was conducted that consisted of 23 surgically treated patients in the past 2 years for subcondylar fractures. Only patients with pre-operative malocclusion and who underwent open reduction with internal fixation with the transmasseteric anteroparotid (TMAP) approach were included. Exclusion criteria included 1) patients treated with closed reduction 2) patients who failed the minimum of 1, 3, and 6-week post-operative visits. The examined parameters were the degree of mouth opening, occlusal relationship, facial nerve function, incidence of salivary fistula and results of imaging studies. Results: 20 of the surgically treated patients met the inclusion criteria. Two patients were excluded due to poor post-operative follow up and 1 was a revision of an attempted closed reduction by an outside surgeon that presented with pre-existing complications. There were no cases of temporary or permanent facial nerve paralysis reported. There were 3 salivary fistulas and 2 sialoceles, which were managed conservatively and resolved within 2 weeks, and 2 cases of inadequate post-surgical maximal incisal opening (<40 mm) were observed. Conclusion: The transmasseteric anteroparotid approach is a safe approach for open reduction and internal fixation of low condylar neck and subcondylar fractures, and it has minimal complications.
