Tacrolimus toxicity due to enzyme inhibition from ritonavir.

Tacrolimus is commonly used for immunosuppression in patients following solid organ transplantation. For transplant patients with COVID-19 infection, early treatment is indicated due to the risk of progression to severe disease. However, the first line agent, nirmatrelvir/ritonavir, has multiple drug-drug interactions. We report a case of tacrolimus toxicity in a patient with a history of renal transplant due to enzyme inhibition related to nirmatrelvir/ritonavir. An 85-year-old woman with a history of multiple comorbidities presented to the emergency department (ED) with weakness, increasing confusion, poor oral intake, and inability to walk. She had been recently diagnosed with COVID-19 infection and was prescribed nirmatrelvir/ritonavir due to her underlying comorbidities and immune suppression. In the ED, she was dehydrated and had an acute kidney injury (creatinine 2.1 mg/dL, up from a baseline of 0.8 mg/dL). The tacrolimus concentration on initial labs was 143 ng/mL (5-20 ng/mL) and it continued to rise despite being held, to a peak of 189 ng/mL on hospital day 3. The patient was treated with phenytoin for enzyme induction and the tacrolimus concentration began to fall. She was discharged to a rehabilitation facility after a 17 day hospitalization. ED physicians must be cognizant of drug-drug interactions when prescribing nirmatrelvir/ritonavir and evaluating patients recently treated with the drug to identify toxicity due to these interactions.

Chiari I malformation with Klippel-Trenaunay syndrome: case report and review of the literature.

We present a rare case of an 8-year-old male with Klippel-Trenaunay syndrome (KTS) and a Chiari I malformation (CIM). Magnetic resonance imaging (MRI) to investigate facial asymmetry and speech delay at age two revealed CIM with cerebellar tonsils 1.3 cm below the foramen magnum without syringomyelia. The patient underwent a craniectomy and posterior fossa decompression with C1 laminectomy. While gene sequencing determined the patient was negative for the PIK3CA gene mutation, the patient's clinical history strongly suggests KTS. He has hemihypertrophy, leg length discrepancy, hemangiomas and pigmentary mosaicism along the upper and lower extremities, heart murmur, chronic low heart rate, recurrent hip pain, and mild scoliosis. Neurodevelopmental concerns include difficulty reading, attention deficit hyperactivity disorder (ADHD), anxiety, and difficulty running and going downstairs. His most recent MRI shows good decompression at the cervicomedullary junction, global cerebrospinal fluid (CSF) flow, and less peg-like cerebellar tonsils. Also noted were two intravertebral hemangiomas at T5 and T6. While the patient's speech has improved, there is still difficulty with the expressive language. He still has mild delays, runs slowly, and does not alternate feet when climbing stairs. The patient is being followed by multiple specialists including neurology, hematology-oncology, genetics, orthopedic surgery, and developmental pediatrics.

Prevalence of and Barriers to Health Disparities Education Among Otolaryngology Residency Curricula.

Objective: To assess the prevalence of health disparities curricula in otolaryngology residency programs and identify implementation barriers. Study Design: Cross-sectional survey. Setting: National otolaryngology residency programs. Methods: A survey based on published literature discussing the incorporation of health disparities curricula, educational design, quality, barriers to implementation, and patient demographics was sent to US otolaryngology residency program directors (PDs). Otolaryngology programs excluded from consideration included those of osteopathic recognition, programs outside of the United States, and military programs. In excluding osteopathic, international, and military-based residency programs from our survey, we aimed to maintain sample homogeneity and focus our analysis on allopathic programs due to potential variations in demographic compositions and practice settings. This decision was made to ensure a more targeted examination of health disparities within a specific context, aligning with our research objectives and resource constraints. Anonymous survey results were collected and analyzed to determine the prevalence of health disparities curricula as well as their effectiveness and standardization across residency programs. Results: A total of 24 PDs (response rate, 23%) responded to the survey. Half of the PDs reported having a health disparities curriculum, among whom only 25% felt the quality of their curriculum was very good or excellent. All institutions with an explicit health disparities educational program reported having developed their own curriculum, 75% of which changed annually. However, 92% of these programs reported not measuring outcomes to assess their curriculum's utility. The most reported barriers to curriculum development for all programs included insufficient time (63%), limited teaching ability specific to health disparities education (54%), and faculty disinterest in teaching (33%). Conclusion: Very few of the surveyed otolaryngology residency programs have implemented a health disparities curriculum. A comprehensive and standardized health disparities curriculum would be beneficial to ensure that residents can confidently develop competency in health disparities, aligning with the Clinical Learning Environment Review mandate and Accreditation Council for Graduate Medical Education expectations.

The empty code cart: Drug shortages over time.

DISCLAIMER: In an effort to expedite the publication of articles, AJHP is posting manuscripts online as soon as possible after acceptance. Accepted manuscripts have been peer-reviewed and copyedited, but are posted online before technical formatting and author proofing. These manuscripts are not the final version of record and will be replaced with the final article (formatted per AJHP style and proofed by the authors) at a later time. PURPOSE: In high-acuity situations such as cardiac arrest, clinicians rely on prepared medications stocked in code carts to provide timely and accurate pharmacotherapy. We examined shortage trends for medications commonly used in code carts. METHODS: Drug shortage data from 2001 to 2022 were retrieved from the University of Utah Drug Information Service (UUDIS) to characterize shortages reported for commonly used code cart medications. Data extracted included the number of shortages, shortage duration, drug characteristics, and reason for the shortage. RESULTS: From 2001 to 2022, 71 drug shortages for code cart medications were reported. The number of new shortages peaked in 2010, and the number of total shortages peaked in 2010. At the end of the study period, 61 (84.7%) shortages had been resolved. For resolved shortages, the mean shortage duration was 18.2 months. The drug with the greatest number of reported shortages was dextrose (10 total), the drug with the longest resolved shortage was calcium chloride injection (116 months), and the drug with the longest active shortage was atropine injection (165 months at the end of the study period). Throughout the entire study period, only 2 suppliers provided commercially available prefilled syringes of dextrose for stocking on code carts. The most common reason for shortages, when reported, was manufacturing delays. CONCLUSION: Medications commonly used in code carts were frequently impacted by drug shortages, which have the potential to impact patient care. Institutional protocols for mitigation and larger efforts to promote a more resilient drug supply chain are critical to ensure patient safety and quality care.

Perioperative Patient-Initiated Communication in Gender-Affirming Mastectomy.

Background: Gender-affirming mastectomy (GAM) improves the psychosocial functioning and quality of life of transgender and non-binary (TGNB) individuals. However, the perioperative period is often marked by emotional stress, concerns about surgical outcomes, and physical discomfort. While inpatient procedures provide multiple opportunities to engage with and educate patients, outpatient surgeries, such as GAM, pose a unique challenge as patients are followed for <24 h postoperatively. Given the heightened emotional and psychological distress related to gender dysphoria TGNB individuals often experience, addressing these gaps can significantly improve outcomes. This study aims to characterize patient and surgical characteristics associated with patient-initiated communication (PIC) frequency in this population. Methods: A single-center retrospective review of TGNB patients undergoing GAM from February 2018 to November 2022 was conducted. Demographics, surgical characteristics, and frequency of and reasons for perioperative PIC (30 days before and after surgery) were recorded. The primary outcome was the incidence of perioperative PIC. The secondary outcomes included (1) the rationale for PIC and (2) patient and surgical characteristics associated with PIC. Results: A total of 352 patients were included. Of these, 285 (74.6%) initiated communication in the perioperative period, totaling 659 PICs. The median age was 25.0 (interquartile range [IQR]: 9.0) years. The median body mass index (BMI) was 28.5 (IQR: 8.5) kg/m2. The mean number of PICs was 0.7 ± 1.3 preoperatively and 1.3 ± 1.7 postoperatively (p < 0.001). The most frequent preoperative PIC subjects were administrative issues (AI; n = 66, 30.7%), preoperative requirements (n = 43, 20.0%), and cost and insurance (n = 33, 15.0%). The most frequent postoperative PIC subjects were wound care (n = 77, 17.3%), AI (n = 70, 15.0%), activity restrictions (n = 60, 13.5%), drainage (n = 56, 12.6%), and swelling (n = 37, 8.3%). Collectively, older patients (ß = 0.234, p = 0.001), those with a history of major depressive disorder or generalized anxiety disorder (2.4 ± 3.0 vs. 1.7 ± 1.9; p = 0.019), and those without postoperative drains (n = 16/17, 94.1% vs. n = 236/334, 70.7%; p = 0.025) engaged in higher levels of PIC. There were no significant associations between other patient characteristics, perioperative details, or complications and PIC frequency. Conclusions: Perioperative PIC is prevalent among the majority of GAM patients at our institution, with age, psychiatric diagnosis, and postoperative drain use identified as significant predictors. To mitigate PIC frequency, it is crucial to ensure adequate support staffing and provide comprehensive postoperative instructions, particularly concerning activity restrictions and drainage management. These interventions may reduce PICs in high-volume centers. Further research should investigate targeted interventions to further support TGNB patients during the perioperative period.

Understanding delays to parathyroidectomy: A mixed-methods approach.

BACKGROUND: Patients from ethnic and racial minority groups with primary hyperparathyroidism may have greater time delays to curative parathyroidectomy. Contributing factors are unclear. METHODS: This was a sequential mixed-methods study. The quantitative phase was a retrospective chart review of adults with primary hyperparathyroidism who underwent parathyroidectomy between 2015 and 2020, collecting demographic and clinical data. Social vulnerability of the patients' residential area, measured with the Social Vulnerability Index, and relevant clinical time intervals were calculated. A multivariable analysis of factors associated with greater time intervals was performed. The qualitative phase involved semistructured interviews with endocrinologists, analyzed inductively for themes. RESULTS: On chart review of 1,083 patients, the median age was determined to be 61 years and 856 (79%) were female. Six hundred twenty-eight (57.9%) were non-Hispanic White and 456 (42.1%) were Hispanic ethnicity or Asian, Pacific Islander, Black, Native American, Other or Unknown race. Patients of Hispanic ethnicity, or Asian or Pacific Islander, Black, Native American, Other or Unknown race were more likely than non-Hispanic White patients to live in the most socially vulnerable areas (19.3% vs 5.9%, P < .01) and had greater time intervals than non-Hispanic White patients between index hypercalcemia and first parathyroid hormone level, surgical referral, or parathyroidectomy (all P < .05). On multivariable analysis, age (coefficient 7.9, 95% CI 2.8-13.0) and living in the most socially vulnerable areas (coefficient 297.9, 95% CI 87-508.7) were associated with greater days between index hypercalcemia and parathyroidectomy. In the study's qualitative phase, identified themes for reasons for care delays included socioeconomic, nonsocioeconomic patient, and nonsocioeconomic nonpatient factors. CONCLUSION: Care delays are driven by a combination of socioeconomic and nonsocioeconomic factors.
