Abstract Objective This study aimed to characterize risk factors for inpatient mortality in patients born with gastroschisis in a contemporary cohort. Study Design This was a retrospective cohort study of infants born with gastroschisis using the Kids' Inpatient Database 2016. Simple descriptive statistics were used to characterize the patients by demographics, and illness severity was estimated using the All-Patient Refined Diagnosis-Related Groups classification. Variables associated with an increased risk of mortality on univariate analysis were incorporated into a multivariable logistic regression model to generate adjusted odds ratios (aORs) for mortality. Results An estimated 1,990 patient with gastroschisis were born in 2016, with a 3.7% mortality rate during the initial hospitalization. Multivariable logistic regression demonstrated the following variables to be associated with an increased risk of inpatient mortality: black or Asian race compared with white (aOR: 2.6, 95% confidence interval [CI]: 1.1–6.1, p = 0.03 and aOR: 4.1, 95% CI: 1.3–13.3, p = 0.02, respectively), whereas private health insurance compared with government (aOR: 0.2; 95% CI: 0.2–0.8; p = 0.007) and exurban domicile compared with urban (aOR: 0.5; 95% CI: 0.2–0.9; p = 0.04) appeared to be associated with a decreased risk of inpatient mortality. Conclusion Inpatient mortality for neonates with gastroschisis is relatively low. Even after correcting for illness severity, race, health insurance status, and domicile appear to play a role in mortality disparities. Opportunities may exist to further decrease mortality in at-risk populations.

Elbow Injuries

Objectives: With the incidence of Little League elbow increasing, pitch limit recommendations for preventing throwing injuries have been developed in the United States and Japan. In 1995, the Japanese Society of Clinical Sports Medicine announced limits of 50 pitches per day and 200 pitches per week to prevent throwing injuries in younger than 12 years old. However the relationship between pitch limit recommendation and elbow injuries among pitchers has not been adequately studied. The aim of our study was to evaluate the association between pitch counts and elbow injuries in youth pitchers. Methods: A total of 149 pitchers without prior elbow pain were observed prospectively for 1 season to study injury incidence in relation to specific risk factors. Average age was 10.1 years (range, 7-11 years). One year later, all pitchers were examined by questionnaire. Subjects were asked whether they had experienced any episodes of elbow pain during the season. The questionnaire was also used to gather data on pitch counts per day and per week, age, number of training days per week, and number of games per year. We investigated the following risk factors for elbow injury: pitch counts, age, position, number of training days per week, and number of games per year. Data were analyzed by multivariate logistic regression models and presented as odds ratio (OR) and profile likelihood 95% confidence interval (CI) values. The likelihood-ratio test was also performed. A two-tailed P value of less than .05 was considered significant. All analysis was done in the SAS software package (version 8.2). Results: Of the 149 subjects, 66 (44.3%) reported episodes of pain in the throwing elbow during the season. 1. Analysis for pitch count per day Univariate analysis showed that elbow pain was significantly associated with more than 50 pitches per day. Multivariate analysis showed that more than 50 pitches per day (OR, 2.44; 95% CI, 1.22-4.94), and more than 70 games per year (OR, 2.47; 95% CI, 1.24-5.02) were risk factors significantly associated with elbow pain. Age and number of training days per week were not significantly associated with elbow pain. 1. Analysis for pitch count per week Univariate analysis showed that elbow pain was significantly associated with more than 200 pitches per week. Multivariate analysis showed that more than 200 pitches per week (OR, 2.04; 95% CI, 1.03-4.10), and more than 70 games per year (OR, 2.41; 95% CI, 1.22-4.87) were risk factors significantly associated with elbow pain. Age was not significantly associated with elbow pain. Conclusion: A total of 44.3% of youth baseball pitchers had elbow pain during the season. Multivariable logistic regression revealed that elbow pain was associated with more than 50 pitches per day, more than 200 pitches per week, and more than 70 games per year. Previous studies have revealed the risk factor with the strongest association to injury is pitcher. Our data suggest that compliance with pitch limit recommendations including limits of 50 pitches per day and 200 pitches per week may be protective against elbow injuries. Those who played more than 70 games per year had a notably increased risk of injury. With increasing demand on youth pitchers to play more, there is less time for repair of bony and soft tissues in the elbow. In conclusion, among youth pitchers, limits of 50 pitches per day, 200 pitches per week, and limits of 70 games per year may protect elbow injuries.

Background: Medication errors account for nearly 250 000 deaths in the United States annually, with approximately 60% of errors occurring during transitions of care. Previous studies demonstrated that almost 80% of participants with human immunodeficiency virus (HIV) have experienced a medication error related to their antiretroviral therapy (ART). Objective: This retrospective chart review examines propensity and type of ART-related errors and further seeks to identify risk factors associated with higher error rates. Methods: Participants were identified as hospitalized adults ≥18 years old with preexisting HIV diagnosis receiving home ART from July 2015 to June 2017. Medication error categories included delays in therapy, dosing errors, scheduling conflicts, and miscellaneous errors. Logistic regression was used to examine risk factors for medication errors. Results: Mean age was 49 years, 76.5% were men, and 72.1% used hospital-supplied medication. For the primary outcome, 60.3% (41/68) of participants had at least 1 error, with 31.3% attributed to delays in therapy. Logistic regression demonstrated multiple tablet regimens (odds ratio [OR]: 3.40, 95% confidence interval [CI]: 1.22-9.48, P = .019) and serum creatinine (SCr) ≥1.5 mg/dL (OR: 8.87, 95% CI: 1.07-73.45, P = .043) were predictive for risk of medication errors. Regimens with significant drug–drug interactions (eg, cobicistat-containing regimens) were not significantly associated with increased risk of medication errors. Conclusions and Relevance: ART-related medication error rates remain prevalent and exceeded 60%. Independent risk factors for medication errors include use of multiple tablet regimens and SCr ≥1.5 mg/dL.

Abstract Background Previous studies have indicated coronavirus disease 2019 (COVID-19) patients with cancer have a high fatality rate. Methods We conducted a systematic review of studies that reported fatalities in COVID-19 patients with cancer. A comprehensive meta-analysis that assessed the overall case fatality rate and associated risk factors was performed. Using individual patient data, univariate and multivariable logistic regression analyses were used to estimate odds ratios (OR) for each variable with outcomes. Results We included 15 studies with 3019 patients, of which 1628 were men; 41.0% were from the United Kingdom and Europe, followed by the United States and Canada (35.7%), and Asia (China, 23.3%). The overall case fatality rate of COVID-19 patients with cancer measured 22.4% (95% confidence interval [CI] = 17.3% to 28.0%). Univariate analysis revealed age (OR = 3.57, 95% CI = 1.80 to 7.06), male sex (OR = 2.10, 95% CI = 1.07 to 4.13), and comorbidity (OR = 2.00, 95% CI = 1.04 to 3.85) were associated with increased risk of severe events (defined as the individuals being admitted to the intensive care unit, or requiring invasive ventilation, or death). In multivariable analysis, only age greater than 65 years (OR = 3.16, 95% CI = 1.45 to 6.88) and being male (OR = 2.29, 95% CI = 1.07 to 4.87) were associated with increased risk of severe events. Conclusions Our analysis demonstrated that COVID-19 patients with cancer have a higher fatality rate compared with that of COVID-19 patients without cancer. Age and sex appear to be risk factors associated with a poorer prognosis.

Abstract Introduction Venous thromboembolism (VTE) is increasing in children, especially in the tertiary care setting. Hospital-associated VTE (HA-VTE) is a potentially preventable cause of major morbidity and mortality. However, the incidence of HA-VTE VTE is low in children Risk stratification tools may aid in identification of hospitalized high risk pediatric patients who may benefit from VTE prophylaxis. Methods We conducted a case-control study of pediatric patients with HA-VTE (21 years or younger at the time of diagnosis) admitted to the Johns Hopkins Hospital from 2008-2010. Cases were identified using ICD-9 codes for DVT and PE and verified by reviewing hospital records and radiologic imaging reports. HA-VTE was defined as: 1) VTE was diagnosed ≥48 hours after hospital admission without signs/symptoms of VTE on admission, or 2) VTE was diagnosed within 90 days of hospital discharge. Two contemporaneous controls matched for age, sex and admission unit were selected for each case. Records of cases and controls were reviewed for presence of a priori identified putative VTE risk factors at admission. Univariate and conditional multivariable logistic regression analyses with backward elimination were used to develop risk-prediction models. Based on results of univariate analysis, we sought to evaluate two multivariable models, one without length of stay (LOS) with relevance to assessment at admission, and one in which LOS was included with relevance to re-assessment after several days of hospitalization. All variables selected for the multivariable model were tested for interaction with a significance threshold level of p<0.2. Except for this, all hypothesis testing was two tailed and a p value of <0.05 was considered significant. Receiver operator curves (ROC) were constructed using risk factors on multivariate analysis. Results Table 1 lists the results putative risk factors by univariate analysis with a) significantly higher odds of VTE and b) higher odds of VTE but not statistically significant. In multivariable logistic regression analysis, central venous catheter (CVC), VTE predisposition and immobility or LOS >5 days were independently associated with HA-VTE. The combination of CVC and VTE predisposition with either immobility or LOS was predictive of HA-VTE (area under the curve for ROC of 76.6% and 80.6%, Table 2). Conclusion We found independently associated risk factors with that may potentially be used in a predictive model of HA-VTE in children. Further prospective validation studies of these and other risk factors may serve as the basis of future risk-stratified randomized control trials of primary prevention of pediatric HA-VTE.

Abstract Background and Aims AKI is a common and resource intensive complication of cardiopulmonary bypass surgery (CPB) in high income-countries occurring in up to one third of surgeries performed. However, little is known of its incidence and impact in the small island developing states of the Caribbean. We describe the incidence, risk factors and outcomes of AKI following CPB at a referral cardiac centre in Jamaica. Method A review of the Medical Records of adult patients (aged ≥ 18 years) with no prior ESRD or dialysis requirement undergoing CPB at the University Hospital of the West Indies, Mona between January 1, 2016 to June 30, 2019 inclusive was undertaken. Demographics, pre-operative status, intraoperative and post-operative data were abstracted. The primary outcome was all-cause 30-day mortality. AKI was defined as meeting the KDIGO criteria based on the peak serum creatinine measurement obtained within 72 hours post-operatively. Multivariable logistic regression was used to examine the risk factors for and impact of AKI on all-cause mortality. Results Of the 259 persons who underwent CPB in the study period, 211 (58% men, mean age 58.1±12.9 years, median± IQR Euro-score II of 1.4 ± 1.4) met inclusion criteria. AKI occurred in 37.3 % (80) of patients with 43.8% (35) KDIGO I, 32.5% (26) KDIGO II and (19) 23.7% KDIGO III. Renal replacement therapy was required in 3.2% (7) of patients. In a multivariable logistic regression model, baseline CKD (eGFR&lt;60mL/min/1.732m2; odds ratio, 95%CI: 5.32,1.72-15.90), Prolonged bypass time (1.73,1.21-2.48; per hour), intraoperative PRBC transfusion (2.33,1.08-5.03) and elevated 24-hour post-operative Neutrophil/Lymphocyte ratio&gt;18 (3.00, 1.07-8.35) were associated with an increased risk of AKI. AKI after CPB resulted in greater hospital (23.6 versus 14.6 days, p&lt;0.001) and ICU stay (8.1 versus 3.3 days, p&lt;0.001) and a 6-fold increase in 30-day mortality after adjusting for age and sex (HR, 95 CI: 6.40, 2.38-17.25). (see Figure 1 Kaplan Meier survival estimates for AKI) Conclusion The occurrence of AKI following CPB is comparable to that reported in the literature and is associated with poor short-term outcomes. Larger multicentre prospective studies to predict risk, identify interventions to reduce mortality and assess long term complications of AKI following CPB in Caribbean countries are needed.

Recent advances in ECLS technology have led to the adoption of centrifugal pumps for the majority of patients worldwide. Despite several advantages of centrifugal pumps, they remain controversial because a number of studies have shown increased rates of hemolysis. The aim of this study was to assess the impact of transitioning from roller to centrifugal pumps on hemolysis rates at our center. A retrospective analysis of all pediatric ECMO patients at a single center between 2005 and 2017 was undertaken. Hemolysis was defined as a plasma free hemoglobin >50 mg/dL. Multivariable logistic regression was performed correcting for several factors to determine risk factors for hemolysis and analyze outcomes among patients with hemolysis. Significant findings were those with p < 0.05. A total of 590 patients were identified during the study period. Multivariable logistic regression for risk factors for hemolysis showed roller pumps (OR 1.92, CI 1.11–3.33) and ECMO duration (OR 1.002 per hour, CI 1.00–1.01) to be significant factors. Rates of hemolysis significantly improved following conversion from roller to centrifugal pumps, with significantly lower rates of hemolysis in 2012, 2015, 2016, and 2017 when compared to the historical average with roller pumps from 2005 to 2009 (34.7%). Additionally, hemolysis was associated with an increased risk of death (OR 3.59, CI 2.05–6.29) when correcting for other factors. These data suggest decreasing rates of hemolysis with centrifugal pumps compared to roller pumps. Since hemolysis was also associated with increased risk of death, these data support the switch from roller to centrifugal pumps at ECMO centers.

OBJECTIVE Status epilepticus (SE) is associated with significant mortality, cost, and risk of future seizures. In one of the first studies of SE after neurosurgery, the authors assess the incidence, risk factors, and outcome of postneurosurgical SE (PNSE). METHODS Neurosurgical admissions from the MarketScan Claims and Encounters database (2007 through 2015) were assessed in a longitudinal cross-sectional sample of privately insured patients who underwent qualifying cranial procedures in the US and were older than 18 years of age. The incidence of early (in-hospital) and late (postdischarge readmission) SE and associated mortality was assessed. Procedural, pathological, demographic, and anatomical covariates parameterized multivariable logistic regression and Cox models. Multivariable logistic regression and Cox proportional hazards models were used to study the incidence of early and late PNSE. A risk-stratification simulation was performed, combining individual predictors into singular risk estimates. RESULTS A total of 197,218 admissions (218,217 procedures) were identified. Early PNSE occurred during 637 (0.32%) of 197,218 admissions for cranial neurosurgical procedures. A total of 1045 (0.56%) cases of late PNSE were identified after 187,771 procedure admissions with nonhospice postdischarge follow-up. After correction for comorbidities, craniotomy for trauma, hematoma, or elevated intracranial pressure was associated with increased risk of early PNSE (adjusted OR [aOR] 1.538, 95% CI 1.183–1.999). Craniotomy for meningioma resection was associated with an increased risk of early PNSE compared with resection of metastases and parenchymal primary brain tumors (aOR 2.701, 95% CI 1.388–5.255). Craniotomies for infection or abscess (aHR 1.447, 95% CI 1.016–2.061) and CSF diversion (aHR 1.307, 95% CI 1.076–1.587) were associated with highest risk of late PNSE. Use of continuous electroencephalography in patients with early (p < 0.005) and late (p < 0.001) PNSE rose significantly over the study time period. The simulation regression model predicted that patients at high risk for early PNSE experienced a 1.10% event rate compared with those at low risk (0.07%). Similarly, patients predicted to be at highest risk for late PNSE were significantly more likely to eventually develop late PNSE than those at lowest risk (HR 54.16, 95% CI 24.99–104.80). CONCLUSIONS Occurrence of early and late PNSE was associated with discrete neurosurgical pathologies and increased mortality. These data provide a framework for prospective validation of clinical and perioperative risk factors and indicate patients for heightened diagnostic suspicion of PNSE.

Hbv Screening

180 Background: Patients with hepatitis B virus (HBV) infection are at risk of reactivation after chemotherapy. It is unclear whether all patients or only those with certain risk factors should be screened for HBV before chemotherapy. The purpose of our study was to determine the clinical predictors of HBV screening in a single institution. Methods: In this retrospective, cross-sectional study, we evaluated new patients who received chemotherapy between 1/1/04 and 9/30/07. We collected data on patients' demographics, types of cancer and chemotherapy, and HBV risk factors such as a previous ICD-9 code for hepatitis C or other liver conditions. We searched for HBV screening as defined by an HBsAg or anti-HBc test ordered prior to chemotherapy. In univariate analyses, we examined the association between each of the patient-related variables and HBV screening. We then determined predictors of HBV screening in a multivariable logistic regression model. Results: We found 10,729 patients who had chemotherapy during the study period. Overall, 16.7% had HBV screening. All of the following predictors in the univariate analysis were significant for HBV screening at the p<0.01 level: age, gender, ethnicity, U.S. residence, cancer type, chemotherapy type, and having a HBV risk factor. In multivariable logistic regression examining predictors for screening using HBsAg, we found that Asian ethnicity (OR 1.75; 1.16-2.66), hematologic malignancies (OR 22.65; 19.3-26.31), and the receipt of rituxamab (OR 3.71; 3.03-4.48) were significant predictors at the p<0.01 level. Women were less likely to be screened than men (OR 0.68; 0.59-0.78). We repeated the analyses using the anti-HBc screening test, and the results were similar. Overall, 1.5% of the screened patients had a positive HBV test. Conclusions: We found that ethnicity, cancer types, and chemotherapy drugs predict physician-driven HBV screening. Future research is needed to study the predictors of a positive HBV screening test and reactivation of HBV after chemotherapy. [Table: see text]

Abstract Objective To explore the high-risk factors of augmented vertebra recompression after percutaneous vertebral augmentation (PVA) in the treatment of osteoporotic vertebral compression fracture (OVCF) and analyze the correlation between these factors and augmented vertebra recompression after PVA. Methods A retrospective analysis was conducted on 353 patients who received PVA for a single-segment osteoporotic vertebral compression fracture from January 2017 to December 2018 in our department according to the inclusion criteria. All cases meeting the inclusion and exclusion criteria were divided into two groups: 82 patients in the recompression group and 175 patients in the non-compression group. The following covariates were reviewed: age, gender, body mass index (BMI), injured vertebral segment, bone mineral density (BMD) during follow-up, intravertebral cleft (IVC) before operation, selection of surgical methods, unilateral or bilateral puncture, volume of bone cement injected, postoperative leakage of bone cement, distribution of bone cement, contact between the bone cement and the upper or lower endplates, and anterior height of injured vertebrae before operation, after surgery, and at the last follow-up. Univariate analysis was performed on these factors, and the statistically significant factors were substituted into the logistic regression model to analyze their correlation with the augmented vertebra recompression after PVA. Results A total of 257 patients from 353 patients were included in this study. The follow-up time was 12–24 months, with an average of 13.5 ± 0.9 months. All the operations were successfully completed, and the pain of patients was relieved obviously after PVA. Univariate analysis showed that in the early stage after PVA, the augmented vertebra recompression was correlated with BMD, surgical methods, volume of bone cement injected, preoperative IVC, contact between bone cement and the upper or lower endplates, and recovery of anterior column height. The difference was statistically significant (P < 0.05). Among them, multiple factors logistic regression elucidated that more injected cement (P < 0.001, OR = 0.558) and high BMD (P = 0.028, OR = 0.583) were negatively correlated with the augmented vertebra recompression after PVA, which meant protective factors (B < 0). Preoperative IVC (P < 0.001, OR = 3.252) and bone cement not in contact with upper or lower endplates (P = 0.006, OR = 2.504) were risk factors for the augmented vertebra recompression after PVA. The augmented vertebra recompression after PVP was significantly less than that of PKP (P = 0.007, OR = 0.337). Conclusions The augmented vertebra recompression after PVA is due to the interaction of various factors, such as surgical methods, volume of bone cement injected, osteoporosis, preoperative IVC, and whether the bone cement is in contact with the upper or lower endplates.

Abstract Background The efficacy of olanzapine as an antiemetic agent in cancer chemotherapy has been demonstrated. However, few high-quality reports are available on the evaluation of olanzapine’s efficacy and safety at a low dose of 5 mg among patients treated with carboplatin regimens. Therefore, in this study, we investigated the efficacy and safety of 5 mg olanzapine for managing nausea and vomiting in cancer patients receiving carboplatin regimens and identified patient-related risk factors for carboplatin regimen-induced nausea and vomiting treated with 5 mg olanzapine. Methods Data were pooled for 140 patients from three multicenter, prospective, single-arm, open-label phase II studies evaluating the efficacy and safety of olanzapine for managing nausea and vomiting induced by carboplatin-based chemotherapy. Multivariable logistic regression analyses were performed to determine the patient-related risk factors. Results Regarding the endpoints of carboplatin regimen-induced nausea and vomiting control, the complete response, complete control, and total control rates during the overall study period were 87.9, 86.4, and 72.9%, respectively. No treatment-related adverse events of grade 3 or higher were observed. The multivariable logistic regression models revealed that only younger age was significantly associated with an increased risk of non-total control. Surprisingly, there was no significant difference in CINV control between the patients treated with or without neurokinin-1 receptor antagonist. Conclusions The findings suggest that antiemetic regimens containing low-dose (5 mg) olanzapine could be effective and safe for patients receiving carboplatin-based chemotherapy.
