Background & Aims
It has been a challenge to confirm the association between laryngeal symptoms and physiologic reflux disease. We examined the ability of oropharyngeal pH tests (with the Restech Dx-pH system) and salivary pepsin tests (with Peptest) to discriminate between asymptomatic volunteers (controls) and subjects with a combination of laryngeal and reflux symptoms (laryngeal±reflux).
Methods
We performed a physician-blinded prospective cohort study of 59 subjects at a single academic institution. Adult volunteers were recruited and separated into 3 groups based on GerdQ and reflux symptom index scores: controls (n=20), laryngeal symptoms (n=20), or laryngeal+reflux symptoms (n=19). Subjects underwent laryngoscopy and oropharyngeal pH tests and submitted saliva samples for analysis of pepsin concentration. Primary outcomes included abnormal acid exposure and composite (RYAN) score for oropharyngeal pH tests and abnormal mean salivary pepsin concentration based on normative data.
Results
Complete oropharyngeal pH data were available from 53 subjects and complete salivary pepsin data from 35 subjects. We did not observe any significant differences between groups in percent time spent below pH 4.0, 5.0, 5.5, 6.0 or RYAN scores; or percent of subjects with positive results from tests for salivary pepsin (53% vs 40% vs 75%; P=.50, respectively). The laryngeal+reflux group had a significantly higher estimated mean concentration of salivary pepsin (117.9±147.4ng/mL) than the control group (32.4±41.9ng/mL) or laryngeal symptom group (7.5±11.2ng/mL) (P=.01 and P=.04, respectively).
Conclusions
Using current normative thresholds, oropharyngeal pH testing and salivary pepsin analysis are not able to distinguish between healthy volunteers and subjects with a combination of laryngeal and reflux symptoms.
Objective
To determine if there are differences in opioid prescribing among generalist physicians, nurse practitioners (NPs), and physician assistants (PAs) to Medicare Part D beneficiaries.
Design
Serial cross-sectional analysis of prescription claims from 2013 to 2016 using publicly available data from the Centers for Medicare and Medicaid Services.
Subjects
All generalist physicians, NPs, and PAs who provided more than 10 total prescription claims between 2013 and 2016 were included. These prescribers were subsetted as practicing in a primary care, urgent care, or hospital-based setting.
Methods
The main outcomes were total opioid claims and opioid claims as a proportion of all claims in patients treated by these prescribers in each of the three settings of interest. Binomial regression was used to generate marginal estimates to allow comparison of the volume of claims by these prescribers with adjustment for practice setting, gender, years of practice, median income of the ZIP code, state fixed effects, and relevant interaction terms.
Results
There were 36,999 generalist clinicians (physicians, NPs, and PAs) with at least one year of Part D prescription drug claims data between 2013 and 2016. The number of adjusted total opioid claims across these four years for physicians was 660 (95% confidence interval [CI] = 660–661), for NPs was 755 (95% CI = 753–757), and for PAs was 812 (95% CI = 811–814).
Conclusions
We find relatively high rates of opioid prescribing among NPs and PAs, especially at the upper margins. This suggests that well-designed interventions to improve the safety of NP and PA opioid prescribing, along with that of their physician colleagues, could be especially beneficial.
Diabetes mellitus remains one of the leading causes of morbidity and mortality worldwide. According to the Centers for Disease Control and Prevention, approximately 23.6 million people in the United States are affected. Of these individuals, 5-10% have been diagnosed with type 1 diabetes mellitus (TIDM), an autoimmune disease. Although it often appears in childhood, T1DM may manifest at any age. The effects of T1DM can be devastating, as the disease often leads to significant secondary complications, morbidity, and decreased quality of life. Since the late 1960s, surgical treatment for diabetes mellitus has continued to evolve and has become a viable alternative to chronic insulin administration. In this review, the historical evolution, current status, graft efficacy, benefits, and complications of pancreas transplantation are explored.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
