ImportanceApproximately 1 in 6 youth in the US have a mental health condition, and suicide is a leading cause of death among this population. Recent national statistics describing acute care hospitalizations for mental health conditions are lacking.ObjectivesTo describe national trends in pediatric mental health hospitalizations between 2009 and 2019, to compare utilization among mental health and non–mental health hospitalizations, and to characterize variation in utilization across hospitals.Design, Setting, and ParticipantsRetrospective analysis of the 2009, 2012, 2016, and 2019 Kids’ Inpatient Database, a nationally representative database of US acute care hospital discharges. Analysis included 4 767 840 weighted hospitalizations among children 3 to 17 years of age.ExposuresHospitalizations with primary mental health diagnoses were identified using the Child and Adolescent Mental Health Disorders Classification System, which classified mental health diagnoses into 30 mutually exclusive disorder types.Main Outcomes and MeasuresMeasures included number and proportion of hospitalizations with a primary mental health diagnosis and with attempted suicide, suicidal ideation, or self-injury; number and proportion of hospital days and interfacility transfers attributable to mental health hospitalizations; mean lengths of stay (days) and transfer rates among mental health and non–mental health hospitalizations; and variation in these measures across hospitals.ResultsOf 201 932 pediatric mental health hospitalizations in 2019, 123 342 (61.1% [95% CI, 60.3%-61.9%]) were in females, 100 038 (49.5% [95% CI, 48.3%-50.7%]) were in adolescents aged 15 to 17 years, and 103 456 (51.3% [95% CI, 48.6%-53.9%]) were covered by Medicaid. Between 2009 and 2019, the number of pediatric mental health hospitalizations increased by 25.8%, and these hospitalizations accounted for a significantly higher proportion of pediatric hospitalizations (11.5% [95% CI, 10.2%-12.8%] vs 19.8% [95% CI, 17.7%-21.9%]), hospital days (22.2% [95% CI, 19.1%-25.3%] vs 28.7% [95% CI, 24.4%-33.0%]), and interfacility transfers (36.9% [95% CI, 33.2%-40.5%] vs 49.3% [95% CI, 45.9%-52.7%]). The percentage of mental health hospitalizations with attempted suicide, suicidal ideation, or self-injury diagnoses increased significantly from 30.7% (95% CI, 28.6%-32.8%) in 2009 to 64.2% (95% CI, 62.3%-66.2%) in 2019. Length of stay and interfacility transfer rates varied significantly across hospitals. Across all years, mental health hospitalizations had significantly longer mean lengths of stay and higher transfer rates compared with non–mental health hospitalizations.Conclusions and RelevanceBetween 2009 and 2019, the number and proportion of pediatric acute care hospitalizations due to mental health diagnoses increased significantly. The majority of mental health hospitalizations in 2019 included a diagnosis of attempted suicide, suicidal ideation, or self-injury, underscoring the increasing importance of this concern.

Patients with left ventricular assist devices currently require long-term anticoagulation with warfarin. Warfarin requires frequent blood tests and is associated with adverse events when not in the therapeutic range. Apixaban is a possible alternative that is potentially better for compliance and requires no additional testing. The purpose of this study was to compare adverse events in patients with a HeartMate 3 LVAD receiving apixaban versus warfarin. Thirty-five patients underwent HM3 implantation between January 01, 2016 to January 31, 2021. The groups compared were apixaban (n = 15, 43%) and warfarin (n = 20, 57%). All patients received 325 mg aspirin daily. Stroke, bleeding, and death were identified as primary outcomes after LVAD implant. Univariate nonparametric statistical analysis was performed. The median duration of treatment with apixaban was 148 days (37–606 days). The groups were comparable in terms of age (56 vs. 54 years), gender (male, 85% vs. 75%), and renal function (Cr 1.5 vs. 1.4). The apixaban group had significantly higher mean pulmonary artery pressure (41 vs. 34, p = 0.03) and there were more (p < 0.05) ischemic cardiomyopathy and INTERMACS profile >3 in the warfarin group. At 6 months, thrombotic complications and death were not different between the groups. The two deaths in the apixaban group were from right heart failure. The apixaban group had clinically lower rates of bleeding complications (5% vs. 30%). The adverse events of bleeding, stroke, and death were similar in HM3 patients receiving warfarin or apixaban. Apixaban may be a safe alternative anticoagulant therapy in HM 3 LVAD patients.

Background Stentless porcine bioprothesis is a surgical strategy to treat aortic root disease. Use has been limited due to the concern for long‐term valve degeneration. This study evaluated the perioperative and late outcomes of patients with aortic root disease requiring root replacement. Methods A total of 409 patients underwent aortic root replacement by a single surgeon using a stentless porcine bioroot between February 1996 and May 2020. The cohort was divided into two groups (age ≤65 and >65 years). Descriptive statistics were used to analyze the data and Kaplan–Meier curves used to evaluate long‐term outcomes. Results Patients age >65 years were more likely to be female (p = .01), have hypertension (p = .01), require circulatory arrest (p = .01), and have concomitant coronary artery bypass grafting (CABG) (p = .04). Baseline creatinine >1.8 (p = .20), diabetes (p = .06), and ejection fraction (p = .20) were similar between groups. The 1‐, 5‐, and 10‐year survival for patients age ≤65 years were 92%, 87%, and 69%, respectively, significantly better than patients age >65 (88%, 73%, and 43%, respectively) (p < .01, Figure 1). The 1‐, 5‐, and 10‐year freedom from reoperation for patients ≤65 years were 99%, 97%, and 93% versus 99%, 98%, and 96% in patients age >65 years, respectively (p = .24). Conclusion Patients with aortic root disease can be treated with acceptable perioperative outcomes, long‐term survival, and low reoperation rates using a stentless porcine bioprothesis. It should be considered irrespective of age due to its excellent durability and freedom from anti‐coagulation requirement.

Background Per 2010 Infectious Diseases Society of America (IDSA) Clinical Practice Guideline for the Use of Antimicrobial Agents in Neutropenic Patients with Cancer, routine use of fluoroquinolone (FQ) chemoprophylaxis in low-risk populations (defined as those with solid tumors or lymphoma undergoing chemotherapy) is not recommended to prevent febrile neutropenic episodes as it was not found to impact all-cause mortality. Since these guidelines were published, there have been additional randomized trials (RCTs) of FQ chemoprophylaxis in patients with cancer. Our objective was to assess the efficacy of FQ vs placebo in preventing probable or confirmed bacterial infection in patients with cancer who did not have leukemias or hematopoietic stem cell transplant (HSCT). Secondary outcomes of interest included febrile episodes, mortality, and adverse effects of antibiotic use. Methods Medline via PubMed, The Cochrane Central Register of Controlled Trials, and SCOPUS from inception through 2/17/2022 were searched. We included RCTs in English comparing FQ to placebo in preventing neutropenic fever and bacterial infections in patients with cancer who did not have leukemias or HSCT. Results We included 5 RCTs (N= 3158). The rates of probable or confirmed bacterial infection in patients with cancer revealed 541/1562 (34.6%) infections in the FQ group and 679/1560 (43.5%) in the placebo group (OR: 0.68, 95% CI:0.59,0.79, I2 = 57%, p=0.002). In evaluating development of febrile episodes, 300/1566 (19.2%) events were noted in the FQ group and 407/1555 (26.2%) in the placebo group (OR: 0.58, 95% CI:0.41,0.83, I2 = 0%, p&lt; 0.001). Mortality events in the FQ group were 113/1597(7.1%) and 124/1508 (8.2%) in the placebo group (OR: 0.76, 95% CI:0.53,1.1, I2 = 7%, p=0.15). Adverse events associated with antibiotic use in the studies were more frequent in the FQ group. Figure 1Forest Plot of Mortality in included studiesFigure 2Results on Development of Fevers in included studies.Figure 3Forest plot of Probable or Proven Infection in included studies. Conclusion Although evidence does not show that FQ prophylaxis provides mortality benefit, it did show a decrease in development of bacterial infections and febrile episodes. This suggests that treatment may still provide clinical benefit to this population of patients, but must be weighed against risks and consequences of long-term antibiotic use, which were not reported by the included studies.
