Vancomycin Anaphylaxis and Kounis Syndrome Case Report.

Preoperative antibiotic administration has become a standard practice to mitigate the risk of surgical site infections; however, it is not devoid of potential complications. This report delves into the case of a 67-year-old male who underwent a routine preoperative vancomycin infusion prior to an elective total knee arthroplasty and subsequently experienced an unexpected adverse reaction including diaphoresis, cutaneous flushing, hypotension, and eventually unresponsiveness involving cardiovascular collapse and non-ST-segment elevation myocardial infarction (NSTEMI), despite minimal underlying coronary artery disease. The report focuses on the management of the emergent condition at our facility, highlighting the immediate response and following management of additional complications. The successful management led to a full recovery with the electrocardiogram (EKG) returning to the preoperative baseline of sinus rhythm with first-degree atrioventricular (AV) block within two hours of the event. This study contributes valuable insights into the complexities associated with preoperative antibiotic use, underscores the importance of understanding individual patient profiles, and raises awareness of potential risks and strategies to be used for antibiotic administration from a healthcare professional perspective.

Outcomes of upfront plerixafor use for mobilization in germ cell tumor patients.

High-dose chemotherapy with autologous hematopoietic stem cell transplantation (auto-HSCT) improved 5-year overall survival rates in relapsed/refractory germ cell tumors (GCTs) from 10% to 52%. Nearly 30% of GCT patients are deemed poor mobilizers after receiving several lines of prior therapy. There is limited data available regarding upfront plerixafor use in GCT patients. We predicted upfront plerixafor use would increase the amount of stem cells collected preventing subsequent mobilizations and improve time to curative therapy. A retrospective, single center, chart review of adult GCT patients who received plerixafor upfront for mobilization at a single center between January 1, 2013 and August 31, 2021 was performed. The primary objective was to evaluate the rate of successful peripheral blood CD34+ cell collections. Secondary objectives consisted of describing the impact of plerixafor use on mobilization and assessing auto-HSCT related outcomes. Sixteen patients received plerixafor upfront after an average of three prior lines of therapy (range: 2-5 lines). Successful collection (≥4 × 106 CD34+ cells/Kg collected within four days) was achieved in 15 (94%) patients in a median of one apheresis day (interquartile range: 1-2 days). All patients proceeded to an initial auto-HSCT and 12 patients (75%) completed both transplants as planned. Survival at 12 months was 50%. The significantly higher amount of CD34+ cells collected over less apheresis days demonstrated the clinical utility of upfront plerixafor and its potential to facilitate more efficient stem cell mobilization. There is a need for larger randomized studies with upfront plerixafor use in this unique patient population.

Artificial Intelligence-Generated Draft Replies to Patient Inbox Messages.

Importance: The emergence and promise of generative artificial intelligence (AI) represent a turning point for health care. Rigorous evaluation of generative AI deployment in clinical practice is needed to inform strategic decision-making. Objective: To evaluate the implementation of a large language model used to draft responses to patient messages in the electronic inbox. Design, Setting, and Participants: A 5-week, prospective, single-group quality improvement study was conducted from July 10 through August 13, 2023, at a single academic medical center (Stanford Health Care). All attending physicians, advanced practice practitioners, clinic nurses, and clinical pharmacists from the Divisions of Primary Care and Gastroenterology and Hepatology were enrolled in the pilot. Intervention: Draft replies to patient portal messages generated by a Health Insurance Portability and Accountability Act-compliant electronic health record-integrated large language model. Main Outcomes and Measures: The primary outcome was AI-generated draft reply utilization as a percentage of total patient message replies. Secondary outcomes included changes in time measures and clinician experience as assessed by survey. Results: A total of 197 clinicians were enrolled in the pilot; 35 clinicians who were prepilot beta users, out of office, or not tied to a specific ambulatory clinic were excluded, leaving 162 clinicians included in the analysis. The survey analysis cohort consisted of 73 participants (45.1%) who completed both the presurvey and postsurvey. In gastroenterology and hepatology, there were 58 physicians and APPs and 10 nurses. In primary care, there were 83 physicians and APPs, 4 nurses, and 8 clinical pharmacists. The mean AI-generated draft response utilization rate across clinicians was 20%. There was no change in reply action time, write time, or read time between the prepilot and pilot periods. There were statistically significant reductions in the 4-item physician task load score derivative (mean [SD], 61.31 [17.23] presurvey vs 47.26 [17.11] postsurvey; paired difference, -13.87; 95% CI, -17.38 to -9.50; P < .001) and work exhaustion scores (mean [SD], 1.95 [0.79] presurvey vs 1.62 [0.68] postsurvey; paired difference, -0.33; 95% CI, -0.50 to -0.17; P < .001). Conclusions and Relevance: In this quality improvement study of an early implementation of generative AI, there was notable adoption, usability, and improvement in assessments of burden and burnout. There was no improvement in time. Further code-to-bedside testing is needed to guide future development and organizational strategy.

Building Pandemic-Resilient Primary Care Systems: Lessons Learned From COVID-19.

On January 30, 2023, the Biden Administration announced its intention to end the existing COVID-19 public health emergency declaration. The transition to a "postpandemic" landscape presents a unique opportunity to sustain and strengthen pandemic-era changes in care delivery. With this in mind, we present 3 critical lessons learned from a primary care perspective during the COVID-19 pandemic. First, clinical workflows must support both in-person and internet-based care delivery. Second, the integration of asynchronous care delivery is critical. Third, planning for the future means planning for everyone, including those with potentially limited access to health care due to barriers in technology and communication. While these lessons are neither unique to primary care settings nor all-encompassing, they establish a grounded foundation on which to construct higher-quality, more resilient, and more equitable health systems.

Exploring Co-occurring POLE Exonuclease and Non-exonuclease Domain Mutations and Their Impact on Tumor Mutagenicity.

POLE driver mutations in the exonuclease domain (ExoD driver) are prevalent in several cancers, including colorectal cancer and endometrial cancer, leading to dramatically ultra-high tumor mutation burden (TMB). To understand whether POLE mutations that are not classified as drivers (POLE Variant) contribute to mutagenesis, we assessed TMB in 447 POLE-mutated colorectal cancers, endometrial cancers, and ovarian cancers classified as TMB-high ≥10 mutations/Mb (mut/Mb) or TMB-low <10 mut/Mb. TMB was significantly highest in tumors with "POLE ExoD driver plus POLE Variant" (colorectal cancer and endometrial cancer, P < 0.001; ovarian cancer, P < 0.05). TMB increased with additional POLE variants (P < 0.001), but plateaued at 2, suggesting an association between the presence of these variants and TMB. Integrated analysis of AlphaFold2 POLE models and quantitative stability estimates predicted the impact of multiple POLE variants on POLE functionality. The prevalence of immunogenic neoepitopes was notably higher in the "POLE ExoD driver plus POLE Variant" tumors. Overall, this study reveals a novel correlation between POLE variants in POLE ExoD-driven tumors, and ultra-high TMB. Currently, only select pathogenic ExoD mutations with a reliable association with ultra-high TMB inform clinical practice. Thus, these findings are hypothesis-generating, require functional validation, and could potentially inform tumor classification, treatment responses, and clinical outcomes. SIGNIFICANCE: Somatic POLE ExoD driver mutations cause proofreading deficiency that induces high TMB. This study suggests a novel modifier role for POLE variants in POLE ExoD-driven tumors, associated with ultra-high TMB. These data, in addition to future functional studies, may inform tumor classification, therapeutic response, and patient outcomes.

Allaying Pediatric Preoperative Anxiety, Where are we Now? - A Nationwide Survey.

Background: Preoperative anxiety (PA) in children is a common phenomenon associated with various negative patient outcomes. Allaying PA is accepted as a standard of care, but its use is not universal and often overlooked. This survey is designed to evaluate the nationwide current practice patterns and attitudes of anesthesiologists toward the practice of allaying PA in children. Materials and Methods: A questionnaire of 25 questions, including information on methods of relieving PA in children, reasons for noncompliance, and associated complications, was framed. It was circulated among members of the Indian Society of Anaesthesiologists through an online survey of Google Forms and manually. Results: Four hundred and fifty anesthesiologists were surveyed. Responses were predominantly from anesthesiologists practicing in medical colleges across the country. Although 97% of the surveyed respondents practiced anxiety-relieving strategies, only 37% used it consistently. Seventy-three percent of anesthesiologists practiced both pharmacological and nonpharmacological techniques. The most common reason for avoiding premedication was an anticipated difficult airway (88%). Inadequate sedation was a commonly reported problem. Ninety-five percent of participants felt that PA-relieving strategies should be integral to pediatric anesthesia practice. The most common reason for not following these practices was an inadequate hospital infrastructure (67%). Ninety-seven percent of the participants believed that more awareness is required on this crucial perioperative issue. Conclusion: Only 37% of the surveyed anesthesiologists consistently used some form of PA-relieving strategy and the practice varied widely. Further improvement and team approach involving anesthesiologists, surgeons, and nurses is required to ensure the quality of pediatric PA-relieving services and establish it as a standard of care.
