Social Enterprise Model (SEM) for private sector tuberculosis screening and care in Bangladesh.

BACKGROUND: In Bangladesh, about 80% of healthcare is provided by the private sector. Although free diagnosis and care is offered in the public sector, only half of the estimated number of people with tuberculosis are diagnosed, treated, and notified to the national program. Private sector engagement strategies often have been small scale and time limited. We evaluated a Social Enterprise Model combining external funding and income generation at three tuberculosis screening centres across the Dhaka Metropolitan Area for diagnosing and treating tuberculosis. METHODS AND FINDINGS: The model established three tuberculosis screening centres across Dhaka Metropolitan Area that carried the icddr,b brand and offered free Xpert MTB/RIF tests to patients visiting the screening centres for subsidized, digital chest radiographs from April 2014 to December 2017. A network of private and public health care providers, and community recommendation was formed for patient referral. No financial incentives were offered to physicians for referrals. Revenues from radiography were used to support screening centres' operation. Tuberculosis patients could choose to receive treatment from the private or public sector. Between 2014 and 2017, 1,032 private facilities networked with 8,466 private providers were mapped within the Dhaka Metropolitan Area. 64, 031 patients with TB symptoms were referred by the private providers, public sector and community residents to the three screening centres with 80% coming from private providers. 4,270 private providers made at least one referral. Overall, 10,288 pulmonary and extra-pulmonary tuberculosis cases were detected and 7,695 were bacteriologically positive by Xpert, corresponding to 28% of the total notifications in Dhaka Metropolitan Area. CONCLUSION: The model established a network of private providers who referred individuals with presumptive tuberculosis without financial incentives to icddr,b's screening centres, facilitating a quarter of total tuberculosis notifications in Dhaka Metropolitan Area. Scaling up this approach may enhance national and international tuberculosis response.

An empirical analysis of consumers' attitudes toward pharmacies' advertising.

This study investigates current attitudes and opinions toward pharmacies' advertising. The purposes of this study were to determine (a) consumers' attitudes toward advertising by pharmacies and (b) whether age, race, income, marital status, occupation, education, sex, and number of children in household of the consumer accounted for any significant difference in attitudes toward pharmacies that advertise. The intent was to discover information that would be useful to pharmacies in planning marketing strategies and improving the quality of their advertising. The study seems to confirm the belief of many pharmacies that advertising and marketing clearly have a place in the future of pharmacists' services.

Unverifiable Academic Work by Applicants to Primary Care Sports Medicine Fellowship Programs in the United States.

BACKGROUND: In 2008, it was shown that 11% of applications to a primary care sports medicine program contained unverifiable citations for publications. In 2009, the American Medical Society for Sports Medicine changed the application requirements, requiring proof that all claimed citations (publications and presentations) be included with the fellowship application. OBJECTIVE: We determined the rate of unverifiable academic citations in applications to primary care sports medicine fellowship programs after proof of citations was required. METHODS: We retrospectively examined all applications submitted to 5 primary care sports medicine fellowship programs across the country for 3 academic years (2010-2013), out of 108 to 131 programs per year. For claimed citations that did not include proof of publication or presentation, we attempted to verify them using PubMed and Google Scholar searches, a medical librarian search, and finally directly contacting the publisher or sponsoring conference organization for verification. RESULTS: Fifteen of 311 applications contained at least 1 unverifiable citation. The total unverifiable rate was 4.8% (15 of 311) for publications and 11% (9 of 85) for presentations. These rates were lower than previously published within the same medical subspecialty. CONCLUSIONS: After requiring proof of publication and presentation citations within applications to primary care sports medicine fellowship programs, unverifiable citations persisted but were less than previously reported.

An empirical analysis of ethical and professional issues in physicians' advertising: A comparative cross-sectional study.

The purpose of this study is to investigate current attitudes and opinions of physicians' advertising and to compare them to the attitudes expressed 10 years previously. This study was designed to determine (a) consumers' attitudes toward advertising by physicians, and (b) whether age, occupation, income, education, or sex of consumer accounted for any significant difference in attitudes toward physicians who advertise. The study seems to confirm the belief of many marketing professionals that advertising and marketing do not have a place in the management and operation of professional services.

Assessment of white matter injury and outcome in severe brain trauma: a prospective multicenter cohort.

BACKGROUND: Existing methods to predict recovery after severe traumatic brain injury lack accuracy. The aim of this study is to determine the prognostic value of quantitative diffusion tensor imaging (DTI). METHODS: In a multicenter study, the authors prospectively enrolled 105 patients who remained comatose at least 7 days after traumatic brain injury. Patients underwent brain magnetic resonance imaging, including DTI in 20 preselected white matter tracts. Patients were evaluated at 1 yr with a modified Glasgow Outcome Scale. A composite DTI score was constructed for outcome prognostication on this training database and then validated on an independent database (n=38). DTI score was compared with the International Mission for Prognosis and Analysis of Clinical Trials Score. RESULTS: Using the DTI score for prediction of unfavorable outcome on the training database, the area under the receiver operating characteristic curve was 0.84 (95% CI: 0.75-0.91). The DTI score had a sensitivity of 64% and a specificity of 95% for the prediction of unfavorable outcome. On the validation-independent database, the area under the receiver operating characteristic curve was 0.80 (95% CI: 0.54-0.94). On the training database, reclassification methods showed significant improvement of classification accuracy (P < 0.05) compared with the International Mission for Prognosis and Analysis of Clinical Trials score. Similar results were observed on the validation database. CONCLUSIONS: White matter assessment with quantitative DTI increases the accuracy of long-term outcome prediction compared with the available clinical/radiographic prognostic score.

A convenient LC-MS method for assessment of glucose kinetics in vivo with D-[13C6]glucose as a tracer.

BACKGROUND: The isotope-labeled intravenous glucose tolerance test (IVGTT) combined with computer modeling is widely used to derive parameters related to glucose metabolism in vivo. Most of these methods involve use of either (2)H(2)-labeled or (13)C(1)-labeled D-glucose as a tracer with GC-MS to measure the isotope enrichment. These methods are challenging, both technologically and economically. We have developed a novel approach that is suitable for labeled-IVGTT studies involving a large cohort of individuals. METHODS: The tracer, D-[(13)C(6)]glucose, is a low-cost alternative with the significant advantage that the sixth isotope of natural glucose has virtually zero natural abundance, which facilitates isotopomer analysis with <1% labeled glucose in the infusate. After deproteinization of plasma samples collected at various times, glucose is converted to a stable derivative, purified by solid-phase extraction (SPE), and analyzed by HPLC-electrospray ionization mass spectrometry to accumulate the isotope-abundance data for the A+2, A+3, and A+6 ions of the glucose derivative. A 2-pool modeling program was used to derive standard kinetic parameters. RESULTS: With labeled-IVGTT data from 10 healthy male individuals, the values for insulin sensitivity, glucose effectiveness, and the plasma clearance rate estimated with the 2-pool minimal model compared well with values obtained via traditional methods. CONCLUSIONS: The relative simplicity and robustness of the new method permit the preparation and analysis of up to 48 samples/day, a throughput equivalent to 2 complete IVGTT experiments, and this method is readily adaptable to existing 96 well-format purification and analytical systems.

Improvement in the reproducibility of region of interest using an auditory feedback loop: a pilot assessment using dynamic contrast-enhanced (DCE) breast MR images.

PURPOSE: To augment traditional visual data perception of complex multiparametric imaging data sets by adding auditory feedback to improve the delineation of regions of interest (ROIs) in tumor assessment in dynamic contrast-enhanced (DCE) MRI. MATERIALS AND METHODS: In addition to conventional display methodologies, we have created an application window which interfaces with audio output using dynamically loadable sound modules, providing goodness of fit (GF) information through auditory feedback. We have assessed effectiveness of conveying sound information with three independent readers on eight DCE-MR breast image data sets. The assessment was based on either conventional visual only mode or combined visual plus auditory mode. For statistical comparison between two sensory approaches, interobserver repeatability was measured with three different criteria. RESULTS: Adding auditory feedback improves repeatability significantly (P < 0.01), and the enhanced sensory approach had higher repeatability than visual only mode in visually complex breast tumor cases. However, in easy and moderate cases, visual only mode was more reproducible than the combined mode with very high significance (P < 0.001). CONCLUSION: Adding auditory information to visual based image analysis for identifying tumor ROIs provides higher interobserver repeatability for analyzing complex multidimensional/multiparametric medical image data sets with visually difficult lesions to delineate.

Attitudes of dentists and dental patients toward advertising.

Twenty years ago, Hite, Bellizzi, and Andrus (1988) examined the attitudes of dentists and consumers toward advertising. This study re-examines those attitudes to see if significant differences still exist. Based on a sample of dentists and consumers, significant differences were found. While attitude of dentists toward advertising is not as negative as it was 20 years ago, their views still tend to lag behind that of consumers. Further, the marketing tools used by dentists today are not consistent with what is seen by consumers and what consumers view as effective. Implications of these findings are discussed.

The "happy end" effect: colonoscopies provide clues on enhancing marketing training.

With many activities, even unlikely ones such as colonoscopies, it appears that ending procedures are important and affect evaluation of the entire experience. This has been dubbed the "happy end" effect. Training specialists, while acknowledging the importance of endings (e.g., seminar closures, class conclusions, and workshop completions), often place greater emphasis on openers, icebreakers, and starters. A sample of trade publications in the training and development field, as well as professional publications was reviewed. It was found that such resources had significantly higher numbers of articles/exercises and pages devoted to beginning activities than to closings. A number of suggestions are offered on how closing activities could be better incorporated into training and development programs to improve them.
