Pleisiomonas shigelloides bacteremia after catfish injury.

This case of Pleisimonas shigelloides bacteremia resulting after a catfish barb injury highlights an unusual presentation of a common condition that requires alternative therapy for successful treatment. An otherwise healthy male in his early 40s presented to the emergency department with sepsis and rapidly spreading cellulitis shortly after a catfish injury at a freshwater lake. His broad-spectrum antibiotics were narrowed to ciprofloxacin when P. shigelloides grew from his blood culture. The case presents a unique mode of bacteremia, as usually P. shigelloides bacteremia develops in immunocompromised hosts after bowel wall translocation. The venomous nature of catfish barbs also contributed to the severity and rapidity of his presentation secondary to the local tissue effects of envenomation. With proper antibiotics and supportive care, he made a full recovery.

Clinical and neuroradiographic features of fentanyl inhalation-induced leukoencephalopathy.

A man in his late 40s with no known past medical history was unresponsive for an unknown period of time. Crushed pills and white residue were found on a nearby table. On presentation he was obtunded and unresponsive to verbal commands but withdrawing to painful stimuli. The initial urine drug screen was negative, but a urine fentanyl screen was subsequently positive with a level of 137.3 ng/mL. MRI of the brain showed reduced diffusivity and fluid attenuated inversion recovery (FLAIR) hyperintensity symmetrically in the bilateral supratentorial white matter, cerebellum and globus pallidus. Alternative diagnoses such as infection were considered, but ultimately the history and workup led to a diagnosis of fentanyl-induced leukoencephalopathy. Three days after admission the patient became able to track, respond to voice and follow basic one-step commands. The patient does not recall the mechanism of inhalation. While there are case reports of heroin-induced leukoencephalopathy following inhaled heroin use and many routes of fentanyl, this is the first reported case of a similar phenomenon due to fentanyl inhalation.

The contemporary management of cancers of the sinonasal tract in adults.

Sinonasal malignancies make up <5% of all head and neck neoplasms, with an incidence of 0.5-1.0 per 100,000. The outcome of these rare malignancies has been poor, whereas significant progress has been made in the management of other cancers. The objective of the current review was to describe the incidence, causes, presentation, diagnosis, treatment, and recent developments of malignancies of the sinonasal tract. The diagnoses covered in this review included sinonasal undifferentiated carcinoma, sinonasal adenocarcinoma, sinonasal squamous cell carcinoma, and esthesioneuroblastoma, which are exclusive to the sinonasal tract. In addition, the authors covered malignances that are likely to be encountered in the sinonasal tract-primary mucosal melanoma, NUT (nuclear protein of the testis) carcinoma, and extranodal natural killer cell/T-cell lymphoma. For the purpose of keeping this review as concise and focused as possible, sarcomas and malignancies that can be classified as salivary gland neoplasms were excluded.

Analysis of Adverse Events and Intravenous Iron Infusion Formulations in Adults With and Without Prior Infusion Reactions.

Importance: Although iron deficiency is common, it remains unclear which iron repletion strategy is associated with the lowest rate of infusion-related adverse events, and how patients with history of infusion reaction should be managed. Objective: To evaluate rates of infusion reactions among 4 commonly used intravenous iron repletion strategies and determine how readministration was managed in patients with history of reaction. Design, Setting, and Participants: This cohort study included all patients receiving intravenous iron infusion from January 1, 2015, to September 7, 2021, at 6 centers in Portland, Oregon. Participants included a total of 12 237 patients with iron deficiency, not restricted by etiology. Statistical analysis was performed from September to October 2021. Exposures: Type of intravenous iron formulation and concurrent administration of diphenhydramine, epinephrine, famotidine, and/or hydrocortisone, used as surrogate maker of infusion reaction. Main Outcomes and Measures: Incidence of adverse events, including severe events requiring epinephrine, stratified by type of iron formulation, and in patients who received premedication or with history of infusion-related reaction receiving subsequent doses. Results: Among 35 737 unique iron infusions (12 237 patients [9480 (77.5%) women; 717 (5.9%) Black; 10 250 (83.7%) White; mean (SD) age of 51 (20) years]), comprising 22 309 iron sucrose doses, 9067 iron dextran total doses (1771 preceded by test dose, 56 test doses alone), 3147 ferumoxytol doses, and 1214 ferric carboxymaltose doses, incidence of adverse events was 3.9% (n = 1389; 95% CI, 3.7%-4.1%). Rate of infusion events differed among iron formulations: 4.3% (n = 970; 95% CI, 4.1%-4.6%) iron sucrose, 3.8% (n = 345, 95% CI: 3.4%-4.2%) iron dextran (test and full doses or test dose alone), 1.8% (n = 57; 95% CI, 1.4%-2.3%) ferumoxytol, and 1.4% (n = 17, 95% CI, 0.8%-2.3%) ferric carboxymaltose (P < .001). Severe adverse events were exceedingly rare with only 2 documented epinephrine administrations, both associated with iron dextran. Incidence of adverse events among those who received premedication was 23-fold higher compared with those who did not (38.6% vs 1.7%, χ21 = 7324.8; P < .001). Among 873 patients with history of infusion reaction who underwent readministration, the majority received the same formulation, which was associated with significantly higher reaction rate particularly if premedication was administered (68% [95% CI, 64%-72%] vs 32% [95% CI, 26%-41%], respectively), compared with those who received an alternate formulation (21% [95% CI, 11%-35%] vs 5% [95% CI, 2%-12%], respectively) (P < .001). Conclusions and Relevance: These data, and the preponderance of published evidence, suggest that intravenous iron is generally well tolerated with exceedingly low risk of severe reaction, use of premedication and test doses are unnecessary, and that optimal prevention and management of infusion-related reactions warrant further study.

Erythrocytosis and thromboembolic events in transgender individuals receiving gender-affirming testosterone.

Erythrocytosis is a well-recognized consequence of exogenous testosterone, however its prevalence and contributions to thrombosis remain unknown in the context of gender-affirming hormonal therapy. We undertook a retrospective study of transgender and non-binary (TGNB) adults receiving exogenous testosterone. In the retrospective sample, 923 transgender individuals receiving testosterone were identified with 519 having documented pre- and post-testosterone hemoglobin and hematocrit (Hgb/Hct). The mean peak Hgb/Hct was 15.7 g/dL, and 47.0%. Mean time-to-peak Hgb/Hct was 31.2 months; 7.8% developed a hemoglobin >17.5 g/dL, whereas 20% developed a hematocrit of >50%. Testosterone dose reduction occurred in 42% of patients with erythrocytosis and 4.8% underwent phlebotomy. Thromboembolic events occurred in 0.9%, of which 80% had developed erythrocytosis by either Hgb or Hct, including two cases each of superficial and calf vein thrombosis as well as one ischemic stroke. We then performed an analysis of 14,294,784 hospitalizations from the 2016-17 US National Inpatient Sample (NIS), which identified 4141 admissions involving transgender individuals. Of those, seven had erythrocytosis with one concurrent venous thromboembolic event. Hematocrit >50% occurs in up to 20% of transgender individuals receiving testosterone. Despite the high incidence of erythrocytosis, thromboembolic events and hospitalizations involving erythrocytosis were uncommon.

Application of ASCO Value Framework to Treatment Advances in Hepatocellular Carcinoma.

BACKGROUND: Determination of the comparative efficacy of one therapy over another for hepatocellular carcinoma (HCC) can be challenging. Application of a recognized value framework to published studies could objectively compare the potential benefit across available therapies. MATERIALS AND METHODS: An umbrella review of phase III trials for HCC therapies was performed. ASCO Value Framework Net Health Benefit Score version 2 (ASCO-NHB v2) scores, the primary analysis, and European Society of Medical Oncology Magnitude of Clinical Benefit Scale version 1.1 scores, the secondary analysis, were computed using selected drug registration trials. Both scores were compared between drugs that were Food and Drug Administration (FDA)-approved by 2020 and those that were not. RESULTS: Of the 22 studies identified, nine were FDA-approved and 13 were not. Across 22 trials, the median overall survival (OS) was 9.2 months (range, 1.9-16.4 months), with a median gain of 0.35 month (range, 2.3-3.3 months). HCC therapies that were FDA-approved showed longer OS (median 10.7 v 7.9 months, P < .01) and higher ASCO NHB scores (+18.4 v -5.7 scores, P < .01). The median gain in OS was 2.2 months in the approved treatments compared with -0.3 months in the unapproved group, with no difference in progression-free survival between the two groups. CONCLUSION: The nine FDA-approved therapies for HCC have higher mean NHB score than those that were not FDA-approved. The application of ASCO-NHB v2 and other proposed value frameworks could examine data of future therapies for HCC through a patient-oriented approach.

Assessment of Financial Toxicity Among Older Adults With Advanced Cancer.

Importance: Financial toxicity (FT), unintended and unanticipated financial burden experienced by cancer patients undergoing cancer care, is associated with negative consequences and increased risk of mortality. Older patients (≥70 years) with cancer are at risk for FT, yet data are limited on FT and whether oncologists discuss FT with their patients. Objective: To examine the prevalence of FT in older adults with advanced cancer, its association with health-related quality of life (HRQoL), and cost conversations between oncologists and patients. Design, Setting, and Participants: This cross-sectional secondary analysis was performed on baseline data from the Improving Communication in Older Cancer Patients and Their Caregivers study, a cluster randomized trial from 31 community oncology practices across the US that was conducted from October 29, 2014, to April 28, 2017. Participants included 536 patients with advanced cancer who answered 3 questions regarding financial toxicity. Data were analyzed from September 1, 2019, to May 1, 2020. Exposure: Older patients undergoing cancer care treatments. Main Outcomes and Measures: The main outcome looked at FT and its association with HRQoL. Three questions were used to identify patients 70 years or older experiencing FT. Multivariable linear regression models were used to assess the independent associations of FT with HRQoL. A single audio-recorded clinic transcript was analyzed within 4 weeks of enrollment for patients with FT. The framework method was used to identify frequency and themes related to cost conversations. Results: This study evaluated 536 patients 70 years or older with advanced cancer. Ninety-eight patients (18.3%) reported FT; mean (SD) age was 76.4 (5.4) years; 59 (60.2%) were female, 14 (14.3%) were Black/African American, 91 (92.9%) were not employed, and 29 (29.6%) had Medicare as their sole insurance coverage. On multivariate regression analyses, FT was associated with higher levels of depression (ß = 0.81; 95% CI, 0.15-1.48), anxiety (ß = 1.67; 95% CI, 0.74-2.61), and distress (ß = 0.73; 95% CI, 0.08-1.39) and lower HRQoL (ß = -5.30; 95% CI, -8.92 to -1.69). Among those who reported FT, 49% had a conversation with their health care professional about costs. Most conversations (79%) were initiated by oncologists or patients. Four themes were generated from cost conversations: statements regarding cost of care, ability to afford medical prescriptions, indirect consequences associated with inability to work and provide for family, and cost burden in nontreatment domains. Conclusions and Relevance: In this study, among older adults with advanced cancer, FT is associated with worse HRQoL. Almost half of conversations among patients reporting FT demonstrated costs are being actively discussed. Resources and interventions are needed to manage FT.

Associations of Polypharmacy and Inappropriate Medications with Adverse Outcomes in Older Adults with Cancer: A Systematic Review and Meta-Analysis.

BACKGROUND: Polypharmacy (PP) and potentially inappropriate medications (PIM) are highly prevalent in older adults with cancer. This study systematically reviews the associations of PP and/or PIM with outcomes and, through a meta-analysis, obtains estimates of postoperative outcomes associated with PP in this population. MATERIALS AND METHODS: We searched PubMed, Embase, Web of Science, and Cochrane Register of Clinical Trials using standardized terms for concepts of PP, PIM, and cancer. Eligible studies included cohort studies, cross-sectional studies, meta-analyses, and clinical trials which examined outcomes associated with PP and/or PIM and included older adults with cancer. A random effects model included studies in which definitions of PP were consistent to examine the association of PP with postoperative complications. RESULTS: Forty-seven articles met the inclusion criteria. PP was defined as five or more medications in 57% of the studies. Commonly examined outcomes included chemotherapy toxicities, postoperative complications, functional decline, hospitalization, and overall survival. PP was associated with chemotherapy toxicities (4/9 studies), falls (3/3 studies), functional decline (3/3 studies), and overall survival (2/11 studies). A meta-analysis of four studies indicated an association between PP (≥5 medications) and postoperative complications (overall odds ratio, 1.3; 95% confidence interval [1.3-2.8]). PIM was associated with adverse outcomes in 3 of 11 studies. CONCLUSION: PP is associated with postoperative complications, chemotherapy toxicities, and physical and functional decline. Only three studies showed an association between PIM and outcomes. However, because of inconsistent definitions, heterogeneous populations, and variable study designs, these associations should be further investigated in prospective studies. IMPLICATIONS FOR PRACTICE: Polypharmacy and potentially inappropriate medications (PIM) are prevalent in older adults with cancer. This systematic review summarizes the associations of polypharmacy and PIM with health outcomes in older patients with cancer. Polypharmacy and PIM have been associated with postoperative complications, frailty, falls, medication nonadherence, chemotherapy toxicity, and mortality. These findings emphasize the prognostic importance of careful medication review and identification of PIM by oncology teams. They also underscore the need to develop and test interventions to address polypharmacy and PIM in older patients with cancer, with the goal of improving outcomes in these patients.
