Abstract Context: The positive association of elevated fibroblast growth factor-23 (FGF23) with PTH levels in the setting of secondary hyperparathyroidism is paradoxical to the purported effects of FGF23 to suppress PTH secretion. Objective: We used dynamic calcium-mediated suppression of PTH levels in hemodialysis (HD) patients to determine the relationship between FGF23 levels and parathyroid gland function. Design: HD patients with elevated PTH were washed out of vitamin D analogs and/or calcimimetics and then exposed them to a high-calcium dialysate bath designed to suppress PTH. Setting: The study was conducted at an outpatient HD unit of an academic medical center. Participants: Eighteen maintenance HD patients with elevated PTH levels participated in the study. Main Outcome Measures: Ionized calcium (iCa), PTH, and FGF23 levels were measured during HD. The slope of the relationship between iCa and PTH (a marker of parathyroid gland mass) and the iCa level required for a 50% reduction in PTH were determined, and the association of these with FGF23 levels was determined. Results: Increased baseline log FGF23 levels were associated with putative alterations in gland mass as estimated by significantly shallower slopes of the iCa/PTH suppression curves (P = 0.0004), but there was no association between FGF23 and calcium sensing as measured by ionized Ca associated with a 50% suppression of PTH (P = 0.38). FGF23 levels decreased significantly during HD, but this change was not correlated with decrements in either renal phosphate or PTH. Conclusions: High FGF23 levels may be a marker for parathyroid gland hyperplasia in HD patients. Acute reductions in neither PTH nor renal phosphate during dialysis correlated with PTH suppression.

Abstract Background IDSA guidelines recommend the usage of a loading dose when using vancomycin for seriously ill patients to rapidly achieve adequate trough concentrations. While the relationship between vancomycin and nephrotoxicity is the focus of many studies, and with the strength of that relationship still debated, few studies have examined the relationship between vancomycin loading doses and nephrotoxicity. Methods We performed a retrospective cohort study examining vancomycin dosing for internal medicine teaching services’ patients over the 2014–15 academic year at one academic medical center. We generated a list of all hospitalized patients aged 18–85 who received vancomycin and were admitted to a teaching service. Patient data were extracted from the inpatient EMR via manual chart review. Patients were excluded if their pretreatment calculated glomerular filtration rate (GFR) was less than 50 mL/minute, if they received less than three doses of vancomycin, or if their initial dose was subtherapeutic (<10 mg/kg). Nephrotoxicity was determined by 7-day acute kidney injury (AKI) rate. Patients in the loading dose (>20 mg/kg) cohort were compared with those in the standard dose cohort (10–20 mg/kg). Our primary modeling used multi-variable logistic regression with AKI as our outcome of interest. Results 438 of the initial 804 patients were enrolled. The loading dose (n = 365, 83%) and standard dosing (n = 73, 17%) cohorts were not significantly different regarding demographics, GFR, nephrotoxic drug exposure, total vancomycin received, trough levels, or comorbidities, and were only significantly different regarding body mass index (BMI). The 7-day AKI rate was not significantly different between the two arms (6.3% in the standard dosing arm and 8.2% in the loading dose arm P = 0.6). AKI rate significantly increased in both arms in the setting of concurrent piperacillin–tazobactam and vancomycin administration (OR 2.5, P = .04). There was no association between BMI and AKI. Conclusion Few studies have examined the relationship between nephrotoxicity and vancomycin loading doses. The results of this study provide evidence that the use of loading doses is not significantly associated with increased 7-day AKI rate. Disclosures All authors: No reported disclosures.

Abstract Purpose Pharmacy departments and schools of pharmacy have long held professional affiliations. However, the success of each entity is often not interdependent and aligned. In 2010, our institutions found ourselves in a position where the complementary motivations of each aligned to support a more meaningful and committed engagement, leading to the development of the Partnership in Patient Care. The impact of the partnership was evaluated 7 years postimplementation, and both the successes realized and the lessons learned are described. Summary The partnership provided many advantages to our pharmacy department and the school of pharmacy. This initial iteration of the partnership was a strong proof of concept that an intentional approach to the relationship between a school of pharmacy and a pharmacy department can lead to substantive improvements in a wide array of meaningful outcomes. We experienced an increase in the number of student rotation months completed, growth in the American Society of Health-System Pharmacists–accredited residency programs, and enhanced clinical services. However, the partnership was not without challenges. For instance, lack of a formalized tracking method made certain outcomes difficult to track. Conclusion The purposeful establishment of the Partnership in Patient Care, built on the needs of a school of pharmacy and an academic medical center pharmacy department, allowed our institutions to develop an intertwined mission and vision. Over the initial years of the partnership, many successes were realized and lessons were learned. Both the successes and the challenges are serving as the foundation for future iterations of the partnership.

Abstract BACKGROUND Insomnia is a prevalent consequence of cancer diagnosis and treatment. In primary brain tumor (PBT) patients specifically, insomnia has been rated as one of the most severe symptoms and linked with other negative side effects, such as increased fatigue and emotional distress. Despite these findings, research has consistently omitted PBT patients in understanding the detailed effects and treatment for insomnia. METHODS Adult PBT patients (N=74) completed anonymous surveys at routine neuro-oncology appointments at an NCI-designated academic medical center. The surveys included validated measures of insomnia (ISI & PSQI), fatigue (BFI), and other original items (e.g., How would you describe your feelings towards medication treatment for insomnia?). The current investigation aimed to assess: 1) the prevalence of clinically elevated symptoms of insomnia, 2) the relationship between sleep disturbance and daytime fatigue and distress, and 3) patients’ preferences for pharmacological and non-pharmacological treatment for insomnia in PBT patients. RESULTS Of the sampled PBT patients, 38% reported significant sleep disturbance as measured by the PSQI. Moreover, 23% endorsed clinically elevated, moderate-severe symptoms of insomnia as measured by the ISI. Excessive worrying (r =.31) and bad dreams (r =.29, p&lt; .05) were both associated, though not predictive of insomnia severity (p &gt;.05). Insomnia symptoms predicted increased fatigue severity, F(1,72) =52.60, β=.65, p&lt; .001, R2 =.42. Of the patients with clinical insomnia, 59% felt that their symptoms were not well-managed by their medical team; 53% expressed interest in pharmacological treatment and 47% in non-pharmacological treatment. CONCLUSIONS The prevalence and consequences of insomnia identified in PBT patients are similar to that of other cancers, yet the majority of PBT patients with insomnia reported their symptoms were poorly managed. Though there was slight preference for pharmacological treatment, the sizeable proportion of those interested in non-pharmacological treatments warrants investigations into such therapies (e.g., CBT-I) in medical settings

Duodenal aspirates are not commonly collected, but they can be easily used in detection of small intestinal bacterial overgrowth (SIBO). Proton pump inhibitor (PPI) use has been proposed to contribute to the development of SIBO. We aimed to determine the yield of SIBO-positive cultures detected in duodenal aspirates, the relationship between SIBO and PPI use, and the clinical outcomes of patients identified by this method. In a retrospective study, we analyzed electronic medical records from 1263 consecutive patients undergoing upper endoscopy at a tertiary medical center. Aspirates were collected thought out the third and fourth portions of the duodenum, and cultures were considered to be positive for SIBO if they produced more than 100,000 cfu/mL. Culture analysis of duodenal aspirates identified SIBO in one-third of patients. A significantly higher percentage of patients with SIBO use PPIs than patients without SIBO, indicating a possible association. Similar proportions of patients with SIBO improved whether or not they received antibiotic treatment, calling into question the use of this expensive therapy for this disorder.

Objectives To assess the influence of hyperlipidemia on the development of noise-induced hearing loss (NIHL). Study Design This case-control study analyzed data from the Department of Preventive Medicine at one academic medical center in southern Taiwan. Subjects and Methods We collected the laboratory data from routine health examinations administered to workers who were exposed to noise greater than 85 dBA over a one-year period. We analyzed the relationships of cholesterol and triglyceride levels with NIHL. Results A total of 4071 cases were analyzed. After adjusting for age and gender, hypertriglyceridemia was found to be related to NIHL (aOR = 1.281; 95% CI, 1.088–1.507), but hypercholesterolemia was not (aOR = 0.951; 95% CI, 0.795–1.138). Conclusions This study, one of the largest to date to study the relationship between hyperlipidemia and NIHL, found that individuals with hypertriglyceridemia are at greater risk of NIHL. On the basis of this finding, workers exposed to high noise levels should be educated on control of triglyceride levels to help reduce their risk of NIHL.

Antipsychotic Prescribing

Abstract Introduction Delirium is an acute, fluctuating change in mental status, often associated with behavioral manifestations such as agitation. Literature suggests that many patients who continue on antipsychotics for extended management of delirium are not provided instructions for discontinuation. However, there is a positive correlation between consult services and instructions for discontinuation. The objective of this study was to determine the frequency at which patients with delirium were prescribed an antipsychotic at hospital discharge and to characterize discharge antipsychotic prescribing for psychiatric consult and nonconsult cohorts. Methods This study was a retrospective chart review of adult patients with an International Classification of Diseases 10th revision code of delirium who received at least 1 dose of antipsychotic during their admission. Inclusion criteria were all patients aged 18 years or older with a diagnosis of or relating to delirium who were administered antipsychotics during their admission. Results A total of 152 patients were included, of which 43 received a psychiatric consult. Antipsychotics were prescribed at discharge for management of delirium for 52 (34.2%) of 152 total patients. More patients in the psychiatric consult cohort were discharged with an antipsychotic as compared to those in the nonconsult cohort (53.3% vs 26.6%, P =  .02). Discussion Compared to previous studies, patients in this retrospective review were more likely to be discharged on an antipsychotic that was initiated during admission for management of delirium. Findings from this study also align with prior research demonstrating a positive association between antipsychotic discharge instructions and specialty consult recommendations.
