CYP2D6 bioactivates codeine and tramadol, with intermediate and poor metabolizers (IMs and PMs) expected to have impaired analgesia. This pragmatic proof-of-concept trial tested the effects of ...CYP2D6-guided opioid prescribing on pain control.
Participants with chronic pain (94% on an opioid) from seven clinics were enrolled into CYP2D6-guided (n = 235) or usual care (n = 135) arms using a cluster design. CYP2D6 phenotypes were assigned based on genotype and CYP2D6 inhibitor use, with recommendations for opioid prescribing made in the CYP2D6-guided arm. Pain was assessed at baseline and 3 months using PROMIS
measures.
On stepwise multiple linear regression, the primary outcome of composite pain intensity (composite of current pain and worst and average pain in the past week) among IM/PMs initially prescribed tramadol/codeine (n = 45) had greater improvement in the CYP2D6-guided versus usual care arm (-1.01 ± 1.59 vs. -0.40 ± 1.20; adj P = 0.016); 24% of CYP2D6-guided versus 0% of usual care participants reported ≥30% (clinically meaningful) reduction in the composite outcome. In contrast, among normal metabolizers prescribed tramadol or codeine at baseline, there was no difference in the change in composite pain intensity at 3 months between CYP2D6-guided (-0.61 ± 1.39) and usual care (-0.54 ± 1.69) groups (adj P = 0.540).
These data support the potential benefits of CYP2D6-guided pain management.
Diabetic myonecrosis, also called diabetic muscle infarction, is an uncommon complication of uncontrolled diabetes mellitus and is frequently underdiagnosed. The objective of this case report is to ...highlight the challenges in the early diagnosis and treatment of this disease.
A 51-year-old African American woman with a long history of uncontrolled diabetes mellitus presented to her primary care physician with right thigh pain. A diagnosis of diabetes myonecrosis was made on the basis of magnetic resonance imaging, biopsy, and negative autoimmune panel. After failing conservative treatment, the patient was treated with prednisone with gradual improvement of her symptoms. However, she had a recurrence of myonecrosis almost one year after her original presentation, which was also treated with prednisone. The recurrence had a shorter course and the patient recovered well. Challenges to the treatment in this patient were her debilitating pain and her underlying chronic kidney disease.
A high index of suspicion for diabetic myonecrosis is necessary when a patient with diabetes presents with unilateral focal leg pain and swelling. Magnetic resonance imaging and biopsy can help confirm the diagnosis. Prednisone may be considered in patients who lack spontaneous regression with just rest. Educating healthcare professionals about this uncommon condition is of utmost importance in avoiding unnecessary testing and inappropriate treatment.
Pharmacogenetic testing (PGT) is increasingly being used as a tool to guide clinical decisions. This article describes the development of an outpatient, pharmacist-led, pharmacogenetics consult ...clinic within internal medicine, its workflow, and early results, along with successes and challenges. A pharmacogenetics-trained pharmacist encouraged primary care physicians (PCPs) to refer patients who were experiencing side effects/ineffectiveness from certain antidepressants, opioids, and/or proton pump inhibitors. In clinic, the pharmacist confirmed the need for and ordered
and/or
testing, provided evidence-based pharmacogenetic recommendations to PCPs, and educated PCPs and patients on the results. Operational and clinical metrics were analyzed. In two years, 91 referred patients were seen in clinic (mean age 57, 67% women, 91% European-American). Of patients who received PGT, 77% had at least one CYP2C19 and/or CYP2D6 phenotype that would make conventional prescribing unfavorable. Recommendations suggested that physicians change a medication/dose for 59% of patients; excluding two patients lost to follow-up, 87% of recommendations were accepted. Challenges included PGT reimbursement and referral maintenance. High frequency of actionable results suggests physician education on who to refer was successful and illustrates the potential to reduce trial-and-error prescribing. High recommendation acceptance rate demonstrates the pharmacist's effectiveness in providing genotype-guided recommendations, emphasizing a successful pharmacist-physician collaboration.
Cryptococcus infection is caused by one of the two species, Cryptococcus neoformans, or the less common Cryptococcus gattii. While Cryptococcus neoformans commonly infects the immunocompromised ...population, Cryptococcus gattii has been seen more frequently in immunocompetent patients. Many seemingly immunocompetent patients, however, may have unidentified underlying immunodeficiencies. Recently, antigranulocyte-macrophage colony-stimulating (GM-CSF) antibodies have been identified as a risk factor for cryptococcosis. We describe a case of disseminated Cryptococcus gattii infection in a seemingly immunocompetent young man, who is found to have anti-GM-CSF antibodies.
Purpose: We aimed to study the impact of a combined faculty-student book club on education and medical practice as a part of the informal curriculum at the University of Florida College of Medicine ...in the United States.Methods: Sixteen medical students and 7 faculties who participated in the book club were interviewed through phone and recorded. The interview was then transcribed and entered into the qualitative data analysis program QSR NVivo (QSR International, Burlington, MA, USA). The transcripts were reviewed, and thematic codes were developed inductively through collaborative iteration. Based on these preliminary codes, a coding dictionary was developed and applied to all interviews within QSR Nvivo to identify themes.Results: Four main themes were identified from interviews: The first theme, the importance of literature to the development and maintenance of empathy and perspective-taking, and the second theme, the importance of the book club in promoting mentorship, personal relationships and professional development, were important to both student and faculty participants. The third and fourth themes, the need for the book club as a tool for self-care and the book club serving as a reminder about the world outside of school were discussed by student book club members.Conclusion: Our study demonstrated that an informal book club has a significant positive impact on self-care, perspective-taking, empathy, and developing a “world outside of school” for medical school students and faculty in the United States. It also helps to foster meaningful relationships between students and faculty.
To determine if an objective structured clinical examination (OSCE) could be used to evaluate and monitor hand hygiene and personal protective equipment (PPE) proficiency for medical interns in the ...United States.
Interns in July 2015 (N=123, Cohort 1) without OSCE-based contact precaution evaluation and teaching were evaluated early 2016 by OSCE for hand hygiene and PPE proficiency. They performed poorly. Therefore, the new interns entering July 2016 (N=151, Cohort 2) were immediately tested in the same OSCE station as Cohort 1 and provided feedback and teaching. Cohort 2 was then retested in the OSCE station early 2017. The Mann Whitney U test was used to compare Cohort 1 vs. Cohort 2 performances on checklist items. Cohort 2 performance differences at the beginning and end of the intern year were compared using McNemar's X2 test for paired nominal data.
Checklist items were scored, summed and reported as percent correct. In Cohort 2, the mean percent correct was higher in posttest than pretest, 92% vs. 77% )(P <0 .0001). The passing rate (100% correct) was significantly higher, 55% vs. 16%. Comparing Cohort 1 and Cohort 2 at the end of intern year, the mean percent correct was higher for Cohort 2 compared to Cohort 1, 95% vs 90% (P < 0.0001). 55% of the Cohort 2 passed (a perfect score) compared to 24% in Cohort 1 (P < 0.0001).
An OSCE can be utilized to evaluate and monitor hand hygiene and PPE proficiency for interns in the United States.

The effective resident handover during transitions of patient care is a skill that is identified as one of the entrustable professional activities (EPAs) required for entering residency training. ...This study describes the results of an objective structured clinical exam (OSCE) station designed to assess interns’ skills in writing a handover of a standardized patient scenario. In 2015, 130 entering interns, representative of 47 of 125 allopathic medical schools, from 13 residency programs at the University of Florida participated in an OSCE that included a written handover station. A nine-item checklist was used to assess performance of interns on the station. Scores on the station ranged from 11.1 % (1 of 9 items correct) to 88.9 % (8 of 9 items correct). While there were no significant differences in handover performance between males and females or between surgical and non-surgical specialties, interns who graduated from top-50 medical schools performed better than graduates from the medical schools not ranked in the top 50. However, the overall failure rate on the handover station was 73 %. This study demonstrates that, despite the fact that the handover is an identified EPA, our interns did not enter residency with the skillset required to successfully demonstrate the required key components of a written patient handover. This demonstrates an undergraduate curricular need for the newly identified EPA that must be addressed.
During their metacyclic developmental stage, African trypanosomes are coated with one of 12–15 variant surface glycoproteins (VSGs) that define different metacyclic variant antigen types (MVATs). The ...MVAT VSG genes are located near telomeres of large chromosomes and are expressed without rearrangement in the metacyclic stage. We have cloned and examined the telomere-linked MVAT5 VSG gene and its upstream expression site associated gene (ESAG I) which are separated by 4.5 kb. Within this 4.5-kb intergenic region is an 87-bp sequence that serves as a strong promoter for a luciferase reporter gene in transient transfection assays. This 87-bp sequence is similar, but not identical, to the promoter for another MVAT VSG gene. UV irradiation experiments were used to detect RNA synthesis from this MVAT5 promoter in bloodstream trypanosomes expressing an unrelated VSG. We propose that this sequence is a specific promoter for the MVAT5 VSG mRNA that occurs in about 10% of the trypanosome population during the metacyclic stage of the parasites' life cycle.
