An epidemiologic study comparing cancer- and noncancer-associated venous thromboembolism in a racially diverse Southeastern United States county.

Background: Cancer-associated venous thromboembolism (CA-VTE) represents a major cause of morbidity and mortality in patients with cancer. Despite poor outcomes, there is an ongoing knowledge gap in epidemiologic data related to this association. Objectives: To compare venous thromboembolism (VTE) characteristics, risk factors, and outcomes between patients with and without active cancer in a racially diverse population. Methods: Our surveillance project occurred at the 3 hospitals in Durham County, North Carolina, from April 2012 through March 2014. Electronic and manual methods were used to identify unique Durham County residents with VTE. Results: We identified 987 patients with VTE during the surveillance period. Of these, 189 patients had active cancer at the time of their VTE event. Patients with CA-VTE were older (median age: 69 years vs 60 years, P < .0001) and had a lower body mass index (median body mass index: 26.0 kg/m2 vs 28.4 kg/m2, P = .0001) than noncancer patients. The most common cancers in our cohort were gastrointestinal, breast, genitourinary, and lung. The proportion of VTE cases with pulmonary embolism (PE) was greater in the cancer cohort compared with that in the noncancer cohort (58.2% vs 44.0%, P = .0004). Overall survival was lower in the CA-VTE group than in patients without cancer (P < .0001). Black patients with CA-VTE had lower proportion of PE (52.3% vs 67.1%, P = .05) but had decreased survival (P < .0003) in comparison with White patients. Conclusion: Future studies may be needed to continue to evaluate local and national VTE data to improve VTE prevention strategies and CA-VTE outcomes.

An Adaptive Pragmatic Randomized Controlled Trial of Emergency Department Acupuncture for Acute Musculoskeletal Pain Management.

STUDY OBJECTIVE: Acute musculoskeletal pain in emergency department (ED) patients is frequently severe and challenging to treat with medications alone. The purpose of this study was to determine the feasibility, acceptability, and effectiveness of adding ED acupuncture to treat acute episodes of musculoskeletal pain in the neck, back, and extremities. METHODS: In this pragmatic 2-stage adaptive open-label randomized clinical trial, Stage 1 identified whether auricular acupuncture (AA; based on the battlefield acupuncture protocol) or peripheral acupuncture (PA; needles in head, neck, and extremities only), when added to usual care was more feasible, acceptable, and efficacious in the ED. Stage 2 assessed effectiveness of the selected acupuncture intervention(s) on pain reduction compared to usual care only (UC). Licensed acupuncturists delivered AA and PA. They saw and evaluated but did not deliver acupuncture to the UC group as an attention control. All participants received UC from blinded ED providers. Primary outcome was 1-hour change in 11-point pain numeric rating scale. RESULTS: Stage 1 interim analysis found both acupuncture styles similar, so Stage 2 continued all 3 treatment arms. Among 236 participants randomized, demographics and baseline pain were comparable across groups. When compared to UC alone, reduction in pain was 1.6 (95% confidence interval [CI]: 0.7 to 2.6) points greater for AA+UC and 1.2 (95% CI: 0.3 to 2.1) points greater for PA+UC patients. Participants in both treatment arms reported high satisfaction with acupuncture. CONCLUSION: ED acupuncture is feasible and acceptable and can reduce acute musculoskeletal pain better than UC alone.

Outcomes by time-to-OR for penetrating abdominal trauma patients.

INTRODUCTION: Time-To-OR is a critical process measure for trauma performance. However, this measure has not consistently demonstrated improvement in outcome. STUDY DESIGN: Using TQIP, we identified facilities by 75th percentile time-to-OR to categorize slow, average, and fast hospitals. Using a GEE model, we calculated odds of mortality for all penetrating abdominal trauma patients, firearm injuries only, and patients with major complication by facility speed. We additionally estimated odds of mortality at the patient level. RESULTS: Odds of mortality for patients at slow facilities was 1.095; 95% CI: 0.746, 1.608; p = 0.64 compared to average. Fast facility OR = 0.941; 95% CI: 0.780, 1.133; p = 0.52. At the patient-level each additional minute of time-to-OR was associated with 1.5% decreased odds of in-hospital mortality (OR 0.985; 95% CI:0.981, 0.989; p < 0.001). For firearm-only patients, facility speed was not associated with odds of in-hospital mortality (p-value = 0.61). Person-level time-to-OR was associated with 1.8% decreased odds of in-hospital mortality (OR 0.982; 95% CI: 0.977, 0.987; p < 0.001) with each additional minute of time-to-OR. Similarly, failure-to-rescue analysis showed no difference in in-hospital mortality at the patient level (p = 0.62) and 0.4% decreased odds of in-hospital mortality with each additional minute of time-to-OR at the patient level (OR 0.996; 95% CI: 0.993, 0.999; p = 0.004). CONCLUSION: Despite the use of time-to-OR as a metric of trauma performance, there is little evidence for improvement in mortality or complication rate with improved time-to-OR at the facility or patient level. Performance metrics for trauma should be developed that more appropriately approximate patient outcome.

Accuracy and Feasibility of Three-Dimensional Ultrasound Testing in Eye Clinic and Emergency Department Patients with Vision Complaints.

BACKGROUND: Ocular emergencies comprise 2-3% of emergency department (ED) visits, with retinal detachment requiring emergency surgery. Two-dimensional ultrasound is a rapid bedside tool but is highly operator dependent. OBJECTIVE: We determined three-dimensional ultrasound (3DUS) feasibility, acceptability, and usability in eye pathology detection using the ophthalmologist examination as reference standard. METHODS: We performed a prospective, blinded cohort study of a 3DUS-enabling device in 30 eye clinic and ED patients with visual symptoms and calculated 3DUS performance characteristics. Two expert readers interpreted the 3DUS images for pathology. All participants completed surveys. RESULTS: 3DUS sensitivity was 0.81, specificity 0.73, positive predictive value 0.54, negative predictive value 0.91, and likelihood ratio (LR)+/LR- 3.03 and 0.26, respectively. Novice and expert sonographers had "substantial" agreement in correct diagnosis of abnormal vs. normal (κ = 0.68, 95% confidence interval 0.48-0.88). Most patients indicated that 3DUS is fast, comfortable, helps them understand their problem, and improves provider interaction/care, and all sonographers agreed; 4/5 sonographers felt confident performing ultrasound. Expert readers correctly identified an abnormal eye in 83/120 scans (76%) and correct diagnosis in 72/120 scans (65%), with no statistical difference between novice (79%; 69%) and expert (72%; 61%) sonographers (p = 0.39, p = 0.55), suggesting reduced operator dependence. Reader diagnosis confidence and image quality varied widely. Image acquisition times were fast for novice (mean 225 ± 83 s) and expert (201 ± 51) sonographers, with fast expert reader interpretation times (225 ± 136). CONCLUSIONS: A 3DUS-enabling device demonstrates a sensitivity of 0.81 and specificity of 0.73 for disease detection, fast image acquisition, and may reduce operator dependence for detecting emergent retinal pathologies. Further technological development is needed to improve diagnostic accuracy in identifying and characterizing retinal pathology.

Predictors of Non-Rhinogenic Facial Pain or Pressure in Otolaryngology Clinic.

OBJECTIVES: Identify demographic and clinical characteristics that may help differentiate non-rhinogenic facial pain or pressure (NRFP) from sinusitis. STUDY DESIGN: Retrospective single-institution study. SETTING: Tertiary Care Center Rhinology Clinic. METHODS: All patients presenting with a complaint of facial pain or pressure over a 3-year period were included. Patients were categorized into either NRFP or sinusitis groups based on computed tomography imaging and nasal endoscopy. Data pertaining to demographics, history, and SNOT-22 questionnaire domains were compared via univariate analysis as well as logistic regression with backwards variable selection. RESULTS: A total of 296 patients met inclusion criteria, of which 128 had NRFP and 168 had sinusitis. A significantly greater percentage of patients in the NRFP group were women of childbearing age (40.6% vs 28.0%, P = .02). Backwards variable selection resulted in a model with four variables predicting a diagnosis of NRFP-female sex (odds ratio [OR] = 2.998, P < .0001), no history of prior sinonasal surgery (OR = 0.340 for history vs no history, P < .01), low nasal domain score (OR = 0.551, P < .0001), and high ear/facial domain score (OR = 1.453, P < .01). CONCLUSION: Accurately identifying patients with NRFP at initial presentation based on history would help direct patients to the appropriate care pathway and prevent ineffective treatments such as antibiotics and sinus procedures. Our findings suggest that the suspicion for NRFP should be higher in women of child-bearing age as well as patients with greater ear/facial symptoms or lesser nasal symptoms.

Short-term cardiovascular events after bariatric surgery in patients with metabolic syndrome.

BACKGROUND: Patients with metabolic syndrome (MetS) are at increased risk of developing cardiovascular disease along with other adverse events after bariatric surgery. OBJECTIVES: The incidence of short-term major adverse cardiovascular events (MACE) in patients with MetS undergoing bariatric surgery is not well characterized. SETTING: Accredited bariatric surgery centers in the United States and Canada. METHODS: A total of 760,076 patients aged ≥18 years with body mass index ≥35 kg/m2 who underwent primary bariatric surgery between 2015 and 2018 were included. Patients with both diabetes and hypertension were described as the MetS cohort. Patient characteristics, operative technique, and 30-day outcomes were compared. The primary outcome was incidence of MACE, a composite of myocardial infarction, stroke, and all-cause mortality. Unadjusted and multivariable logistic regression analyses were performed and included an interaction between MetS and hyperlipidemia (HLD). RESULTS: Of the 577,882 patients included, 111,128 (19.2%) exhibited MetS. Patients with MetS more frequently experienced MACE compared with patients without MetS (.3% versus .1%; P < .001). The odds of MACE were greater for patients with MetS versus Non-MetS (odds ratio [OR] 2.87; 95% CI, 2.49-3.32) in the unadjusted analysis. MetS without HLD, MetS with HLD, and Non-MetS with HLD are significantly associated with MACE when compared with those with non-MetS without HLD. CONCLUSIONS: Patients with MetS have an increased frequency of cardiac events following bariatric surgery. Future studies should determine if optimization of 1 or more components of MetS or other related co-morbidities reduces the cardiovascular risk for patients.

Predictive Factors in Identifying Pediatric Patients at Risk of Diagnostically Limited Videofluoroscopic Swallow Studies.

Objective: Videofluoroscopic swallow studies (VFSS) are highly effective in characterizing pediatric dysphagia, but they are time- and resource-intensive, and necessitate the use of radiation. Identifying patients unlikely to benefit from VFSS is crucial to improving patient safety and resource allocation. The purpose of this study was to assess whether the ability of a patient to consume at least 0.5 oz by mouth is a reliable indicator of their ability to produce a diagnostically useful VFSS. Study Design: Retrospective chart review. Methods: Clinical data of pediatric patients aged 0 to 18 years, who underwent VFSS at a tertiary academic medical center from 2014 to 2021 were analyzed. Results: Regardless of whether due to mechanical dysphagia or oral aversion, an inability to consume at least 0.5 oz of any texture by mouth at home was not found to be associated with nondiagnostic VFSS. Age was found to have an effect on VFSS utility with toddlers having higher odds of nondiagnostic VFSS compared to children and adolescents. Overall, there was no significant interaction between the ability to take at least 0.5 oz and age group. Gastrointestinal (GI) and neuromuscular comorbidities were also associated with clinically useful swallow studies. Conclusions and Relevance: Clinicians should consider several factors, including age, at-home intake by mouth, and comorbidities such as neuromuscular and GI disorders, as they decide whether to order a VFSS.

In hospitalized patients undergoing therapeutic plasma exchange, major bleeding prevalence depends on the bleeding definition: An analysis of The Recipient Epidemiology and Donor Evaluation Study-III.

BACKGROUND: Major bleeding in patients undergoing therapeutic plasma exchange (TPE) has been studied in large databases; but without standardizing bleeding definitions. Therefore, we used standardized definitions to evaluate major bleeding in hospitalized patients undergoing TPE using public use data files from the Recipient Epidemiology and Donor Evaluation Study-III (REDS-III). STUDY DESIGN AND METHODS: In a retrospective cross-sectional analysis, we identified TPE-treated adults in a first inpatient encounter. We evaluated major bleeding prevalence using (1) International Classification of Diseases (ICD) or Current Procedural Terminology (CPT) codes, (2) packed red blood cell (PRBC) transfusion, or (3) hemoglobin (Hgb) decline. Patients with major bleeding prior to their first TPE were excluded from the analysis. RESULTS: Among 779 patients undergoing TPE, major bleeding by at least one of the three bleeding definitions occurred in 135 patients (17.3%). For each of the ICD/CPT, PRBC, and Hgb definitions, the prevalence of major bleeding was 2.8% (n = 31), 7.4% (n = 81), and 5.4% (n = 59), respectively. Only 3.7% of bleeds (5/135) were captured by all three definitions and 19.3% (26/135) exclusively by any two pairwise definitions. The addition of PRBC transfusion and Hgb decline to ICD/CPT code definitions increased bleeding prevalence threefold. CONCLUSION: Among hospitalized adults undergoing TPE in the REDS-III study, the prevalence of major bleeding was 17.3%. The addition of PRBC and Hgb decline to ICD codes increased bleeding prevalence threefold. Future studies are needed to develop validated models that identify patients at risk for major bleeding during TPE.

In patients with suspected immune TTP, admission source impacts hospital length of stay and time to therapeutic plasma exchange impacts clinical outcomes.

INTRODUCTION: When immune thrombotic thrombocytopenic purpura (TTP) is suspected, outcomes are impacted by time to therapeutic plasma exchange (TPE). We evaluated the impact of time to TPE on outcomes in suspected TTP cases admitted through the Emergency Department (ED) vs. transferred from another facility (Transfer). MATERIALS AND METHODS: In a retrospective analysis of the National Inpatient Sample, we examined the association between TTP outcomes and admission source (ED vs. Transfer) for the primary outcome of time to TPE. A second stratified analyses within each analytic group examined the association of time to TPE (<1 day, 1 day, 2 days, and >2 days) and outcomes for the composite outcome of mortality, major bleeding and thrombosis. RESULTS: Of 1195 cases, 793 (66 %) were admitted through the ED and 402 (34 %) were transferred. Compared to ED cases, Transfers had a longer hospital length of stay (14.69 vs. 16.65 days, p = 0.0060). For ED cases, TPE after >2 days was associated with higher odds of the composite outcome (OR = 1.68 95 % CI: 1.11-2.54; p = 0.0150) and mortality (OR = 3.01 95 % CI: 1.38-6.57; p = 0.0056). For Transfers, TPE on day 2 was associated with higher odds of the composite outcome (OR = 3.00 95 % CI: 1.31-6.89; p = 0.0096) and mortality (OR = 4.95 95 % CI: 1.12-21.88; p = 0.0350). CONCLUSIONS: In suspected TTP admitted through the ED or transferred, there was no significant difference in time to TPE. A longer time to TPE was associated with worse outcomes. Future studies should evaluate strategies to decrease initial time to TPE.

Factors Associated With Triage Decisions in Older Adult Trauma Patients: Impact on Mortality and Morbidity.

INTRODUCTION: As medical advances have significantly increased the life expectancy among older adults, the number of older patients requiring trauma care has risen proportionately. Nevertheless, it is unclear among this growing population which sociodemographic and economic factors are associated with decisions to triage and transfer to level I/II centers. This study aims to assess for any association between patient sociodemographic characteristics, triage decisions, and outcomes during acute trauma care presentations. METHODS: The National Trauma Data Bank was queried for patients aged 65 and older with an injury severity score > 15 between the years 2007 to 2017. Factors associated with subsequent levels of triage on presentation were assessed using multivariate logistic regression, and associations of levels of triage with outcomes of mortality, morbidity, and hospital length of stay are examined using logistic and linear regression models. RESULTS: Triage of 210,310 older adult trauma patients showed significant findings. American Indian patients had higher odds of being transferred to level I/II centers, while Asian, Black, and Native Hawaiian patients had lower odds of being transferred to level I/II centers when compared to Caucasian patients (P < 0.001). Regarding insurance, self-pay (uninsured) patients were less likely to be transferred to a higher level of care; however, this was also demonstrated in private insurance holders (P < 0.001). Caucasian patients had significantly higher odds of mortality, with Black patients (odds ratio [OR] 0.80 [0.75, 0.85]) and American Indian patients (OR 0.87 [0.72, 1.04]) having significantly lower odds (P < 0.001). Compared to government insurance, private insurance holders (OR 0.82 [0.80, 0.85]) also had significantly lower odds of mortality, while higher odds among self-pay were observed (OR 1.75 [1.62, 1.90]), (P < 0.001). CONCLUSIONS: Access to insurance is associated with triage decisions involving older adults sustaining trauma, with lower access increasing mortality risk. Factors such as race and gender were less likely to be associated with triage decisions. However, due to this study's retrospective design, further prospective analysis is necessary to fully assess the decisions that influence trauma triage decisions in this patient population.

Systematic Review and Meta-analysis for Surgery Versus Stereotactic Radiosurgery for Jugular Paragangliomas.

OBJECTIVE: Comprehensively analyze tumor control and treatment complications for jugular paraganglioma patients undergoing surgery versus stereotactic radiosurgery (SRS). DATABASES REVIEWED: EMBASE, Medline, and Scopus. METHODS: The databases were searched for English and Spanish articles from January 1, 1995, to January, 1, 2019, for studies reporting tumor control and treatment side effects regarding patients with jugular paraganglioma treated with surgery or SRS. Main outcome measures included short-term and long-term tumor recurrence, as well as postintervention complications. RESULTS: We identified 10,952 original abstracts, 705 eligible studies, and 107 studies for final data extraction. There were 3,498 patients-2,215 surgical patients and 1,283 SRS patients. Bayesian meta-analysis was applied to the extracted data, with tau measurements for study heterogeneity. SRS tumors were larger (3.9 cm 3 versus 8.1 cm 3 ). Meta-analysis results demonstrated low rates of long-term recurrence for both modalities (surgery, 15%; SRS, 7%), with SRS demonstrating lower rates of postintervention cerebrospinal fluid leak, dysphagia, and cranial nerve Vll, lX, X, Xl, or Xll palsies. CONCLUSIONS: This study demonstrates excellent control of jugular paragangiomas with both surgery and SRS, with higher rates of lower cranial neuropathies, dysphagia, and cerebrospinal fluid leaks among surgical patients.

Predictors of Stress-Delta High-Sensitivity Troponin T in Emergency Department Patients Undergoing Stress Testing.

Background and objective Elevations in high-sensitivity troponin T (hs-TnT) are frequently observed following extreme physical exercise. In light of this, we sought to determine whether specific clinical characteristics are associated with this phenomenon in patients undergoing cardiac exercise tolerance testing (ETT). Methods We conducted a retrospective analysis of a prospectively collected biospecimen repository of 257 patients undergoing a stress echocardiogram for possible acute coronary syndrome (ACS). Ischemic electrocardiogram (ECG) changes during ETT and the presence or absence of ischemia on imaging were determined by a board-licensed cardiologist. N-terminal pro-brain natriuretic peptide (NT-proBNP) and hs-TnT assays were obtained immediately before and two hours following ETT. We developed linear regression models including several clinical characteristics to predict two-hour stress-delta hs-TnT. Variable selection was performed using the least absolute shrinkage and selection operator (LASSO). Results The mean age of the patients was 52 years [standard deviation (SD): 11.4]; 125 (48.6%) of them were men, and 88 (34.2%) were African-American. Twenty-two patients (8.6%) had ischemia evident on echocardiography, and 31 (12.1%) had ischemic ECG changes during exercise. The mean baseline hs-TnT was 5.6 ng/L (SD: 6.4) and the mean two-hour hs-TnT was 7.1 ng/L (SD: 10.2). Age and ischemic ECG changes were associated with two-hour stress-delta hs-TnT values. Conclusions Based on our findings, ischemic changes in stress ECG and age were associated with an increase in hs-TnT levels following exercise during a stress echo.

Racial differences in venous thromboembolism: A surveillance program in Durham County, North Carolina.

Background: Venous thromboembolism (VTE) affects approximately 1-2 individuals per 1000 annually and is associated with an increased risk for pulmonary hypertension, postthrombotic syndrome, and recurrent VTE. Objective: To determine risk factors, incidence, treatments, and outcomes of VTE through a 2-year surveillance program initiated in Durham County, North Carolina (population approximately 280,000 at time of study). Patients/Methods: We performed a retrospective analysis of data actively collected from three hospitals in Durham County during the surveillance period. Results: A total of 987 patients were diagnosed with VTE, for an annual rate of 1.76 per 1000 individuals. Hospital-associated VTE occurred in 167 hospitalized patients (16.9%) and 271 outpatients who were hospitalized within 90 days of diagnosis (27.5%). Annual incidence was 1.98 per 1000 Black individuals compared to 1.25 per 1000 White individuals (p < 0.0001), and Black individuals with VTE were younger than White individuals (p < 0.0001). Common risk factors included active cancer, prolonged immobility, and obesity, and approximately half were still taking anticoagulant therapy 1 year later. A total of 224 patients died by 1 year (28.5% of patients for whom outcomes could be confirmed), and Black patients were more likely to have recurrent VTE than White patients during the first 6 months following initial presentation (9.4% vs. 4.1%, p = 0.01). Conclusions: Ongoing surveillance provides an effective strategy to identify patients with VTE and monitor treatment and outcomes. We demonstrated that hospital-associated VTE continues to be a major contributor to the burden of VTE and confirmed the higher incidence of VTE in Black compared to White individuals.

Evaluation of telephone-assisted cardiopulmonary resuscitation recommendations for out-of-hospital cardiac arrest.

AIM OF THE STUDY: While out-of-hospital cardiac arrest (OHCA) is associated with poor survival, early bystander CPR (B-CPR) and telephone CPR (T-CPR) improves survival from OHCA. American Heart Association (AHA) Scientific Statements outline recommendations for T-CPR. We assessed these recommendations and hypothesized that meeting performance standards is associated with increased likelihood of survival. Additional variables were analyzed to identify future performance measurements. METHODS: We conducted a retrospective cohort study of non-traumatic, adult, OHCA using the Singapore Pan-Asian Resuscitation Outcomes Study. The primary outcome was likelihood of survival; secondary outcomes were pre-hospital Return of Spontaneous Circulation (ROSC) and B-CPR. RESULTS: From 2012 to 2016, 2,574 arrests met inclusion criteria. Mean age was 68 ± 15; of 2,574, 1,125 (44%) received T-CPR with 5% (135/2574) survival. T-CPR cases that met the Lerner et al. performance metrics analyzed, demonstrated no statistically significant association with survival. Cases which met the Kurz et al. criteria, "Time for Dispatch to Recognize Need for CPR" and "Time to First Compression," had adjusted odds ratios of survival of 1.01 (95% CI:1.00, 1.02; p = <0.01) and 0.99 (95% CI:0.99, 0.99; p = <0.01), respectively. Identified barriers to CPR decreased the odds of T-CPR and B-CPR being performed. Patients with prehospital ROSC had higher odds of B-CPR being performed. EMS response time < 8 minutes was associated with increased survival among patients receiving T-CPR. CONCLUSION: AHA scientific statements on T-CPR programs serve as ideal starting points for increasing the quality of T-CPR systems and patient outcomes. More work is needed to identify other system performance measures.

The safety of pediatric use of paracetamol (acetaminophen): a narrative review of direct and indirect evidence.

Paracetamol (acetaminophen) use during pregnancy and early childhood was accepted as safe in the 1970s, but is now a subject of considerable concern. Careful analysis shows that initial acceptance of the drug was based on the false assumption that drug interactions in babies and adults are the same, and on a complete absence of knowledge regarding the impact of the drug on brain development. At least fourteen epidemiological studies now indicate that prenatal exposure to paracetamol is associated with neurodevelopmental problems. Based on these studies, it can be concluded that prenatal exposure to paracetamol causes statistically significant risks of developmental delays, attention deficit hyperactivity disorder, and a subtype of autism spectrum disorder (ASD) associated with hyperkinetic behavior. In contrast, data regarding postnatal exposure to paracetamol are limited, and several factors impede a classic multivariate analysis of epidemiologic data to resolve the issue. However, circumstantial evidence regarding postnatal exposure to the drug is abundant, and includes at least three otherwise unexplained temporal relationships, data from laboratory animal studies, several miscellaneous and otherwise unexplained correlations, and a lack of alternative suspects that fit the evidence-derived profile. Based on this evidence, it can be concluded without any reasonable doubt that oxidative stress puts some babies and children at risk of paracetamol-induced neurodevelopmental injury, and that postnatal exposure to paracetamol in those susceptible babies and children is responsible for many if not most cases of ASD.

Endoscopic Sinus Surgery in Older Patients With Significant Medical Comorbidities.

BACKGROUND: Endoscopic sinus surgery (ESS) offers excellent outcomes for patients with chronic rhinosinusitis (CRS) in the general population. It is unclear whether older patients with significant medical comorbidities experience similar benefits. OBJECTIVE: The purpose of this study is to evaluate whether increasing medical comorbidity is associated with worse sinonasal quality of life outcomes after ESS in older patients. METHODS: This is a retrospective study of CRS patients 55 years or older who underwent elective ESS at an academic institution from July 2017 to June 2019. 22-Item Sino-Nasal Outcomes Test (SNOT-22) scores were gathered at baseline as well as at 3 and 6 months following surgery. Data on demographics, medical comorbidities, preoperative Lund-Mackay (LM) scores, and postoperative complications were extracted from the medical record. The Charlson Comorbidity Index (CCI) was calculated for each patient. Multivariate linear regression was used to evaluate a potential association between CCI and change in SNOT-22 scores at 3 months postoperatively. RESULTS: A total of 205 patients met inclusion criteria with a mean (SD) CCI score of 2 (2.4) and a CCI score range of 0 to 11. The mean (SD) LM score was 8 (5.3). Rates of asthma and nasal polyposis were 28.3% and 36.6%, respectively. The mean (SD) improvement in SNOT-22 scores at 3 and 6 months compared to baseline was 17.9 (19.7) and 20.9 (18.1) points, respectively. After adjusting for covariates, there was no significant association between CCI and change in SNOT-22 scores. CONCLUSION: Greater medical comorbidity is not associated with worse SNOT-22 outcomes postoperatively, although future studies are needed to determine if comorbidities are associated with higher complication rates. A multidisciplinary approach to perioperative care is critical in maintaining the safety and efficacy of ESS in this patient population.

Stress-Delta B-Type Natriuretic Peptide Does Not Exclude ACS in the ED.

BACKGROUND: There are many detectable changes in circulating biomarkers in the setting of myocardial ischemia. We hypothesize that there are associated changes in circulating B-type natriuretic peptide (BNP) level after stress-induced myocardial ischemia, which can be used for emergency department (ED) acute coronary syndrome (ACS) risk stratification. METHODS: In a prospective study, we enrolled 340 patients over the age of 30 receiving an exercise echocardiography stress test in an ED observational unit for suspected ACS. We collected blood samples at baseline and at 2 and 4 h post-stress test, measuring the relative and absolute changes (stress-delta) in plasma BNP concentrations. In addition, patients were contacted at 90 days and at 1 year posttest for a follow-up. We calculated the diagnostic test characteristics of stress-delta BNP for a composite outcome of ischemic imaging on stress echocardiogram, nonelective percutaneous coronary intervention, coronary artery bypass graft surgery, subsequent acute myocardial infarction, or cardiac death at 1 year via a logistic regression. We analyzed the 2-h BNP concentrations using an ANOVA model to adjust for the baseline BNP level. RESULTS: Baseline and 2-h post-stress BNP were both higher in the positive outcome group, but the stress-delta BNP was not. Stress-delta BNP had a sensitivity and specificity, respectively, of 53% and 76% at 2 h and 67% and 68% at 4 h. It was noted that patients with the composite outcome had a higher baseline BNP level. CONCLUSIONS: BNP stress-deltas are poor diagnostic means for ACS risk stratification, but resting BNP remains a promising prognostic tool for ED patients with suspected ACS.

Trends in risk factors for readmission after bariatric surgery 2015-2018.

BACKGROUND: Readmission after bariatric surgery is multifactorial. Understanding the trends in risk factors for readmission provides opportunity to optimize patients prior to surgery identify disparities in care, and improve outcomes. OBJECTIVES: This study compares trends in bariatric surgery as they relate to risk factors for all-cause readmission. SETTING: Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP) participating facilities. METHODS: The Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program database was used to analyze 760,076 bariatric cases from 854 centers. Demographics and 30-day unadjusted outcomes were compared between laparoscopic adjustable gastric banding (LAGB), sleeve gastrectomy (LSG), and Roux-en-Y gastric bypass (RYGB) performed between 2015 and 2018. A multiple logistic regression model determined predictors of readmission. RESULTS: A total of 574,453 bariatric cases met criteria, and all-cause readmission rates decreased from 4.2% in 2015 to 3.5% in 2018 (P < .0001). The percentage of non-Hispanic Black adults who underwent bariatric surgery increased from 16.7% of the total cohort in 2015 to 18.7% in 2018 (P < .0001). The percentage of Hispanic adults increased from 12.1% in 2015 to 13.8% in 2018 (P < .0001). The most common procedure performed was the LSG (71.5%), followed by RYGB (26.9%) and 1.6% LAGB (1.6%) (P < .0001). Men were protected from readmission compared with women (odds ratio [OR]: .87; 95% confidence interval [CI]: .84-.90). Non-Hispanic Black (OR: 1.52; 95% CI: 1.47-1.58)] and Hispanic adults (OR: 1.14; 95% CI: 1.09-1.19) were more likely to be readmitted compared with non-Hispanic White adults. LSG (OR: 1.27; 95% CI: 1.10-1.48) and RYGB (OR: 2.24; 95% CI: 1.93-2.60) were predictive of readmission compared with LAGB. CONCLUSION: Readmission rates decreased over 4 years. Women, along with non-Hispanic Black and Hispanic adults, were more likely to be readmitted. Future research should focus on gender and racial disparities that impact readmission.

Central venous catheters are associated with thrombosis among adult inpatients undergoing therapeutic plasma exchange.

BACKGROUND: For inpatients undergoing therapeutic plasma exchange (TPE) in the United States, the primary mode of venous access is the central venous catheter (CVC). To evaluate the impact of CVC on thrombosis outcomes of patients undergoing TPE, we analyzed the National Inpatient Sample (NIS) database. STUDY DESIGN AND METHODS: In a cross-sectional analysis of the NIS, we identified hospital discharges of adult patients treated with TPE. Cases were classified into two groups based on CVC status. The primary outcome was thrombosis. Secondary outcomes were major bleeding, packed red blood cell (PRBC) transfusion, in-hospital mortality, hospital length of stay (LOS), and charges. RESULTS: Among 9863 TPE-treated discharges, CVC was used in 5988 (60%). These numbers correspond to weighted national estimates of 49 315 and 29 940, respectively. There was a positive and significant association between CVC and thrombosis (OR = 1.23, 95% 1.04-1.46, P = 0.0174), PRBC transfusion (OR = 1.15, 95% 1.03-1.29, P = 0.0121), in-hospital mortality (OR = 1.36, 95% 1.10-1.68, P = 0.0043), hospital LOS (15.63 vs 12.45 days, P < 0.0001) and hospital charges ($166 387 vs. $132 655, P < 0.0001). CONCLUSION: In hospitalized patients undergoing TPE, CVC use is associated with increased rates of thrombosis. Future studies are needed to investigate strategies to decrease CVC use and/or prevent CVC-associated complications in TPE-treated inpatients.
