Use of Thromboelastography in Assessment of Snake Bite Coagulopathy.

Background: Monitoring for envenomation coagulopathy following snake bites has traditionally involved using serial coagulation studies.Purpose: Thromboelastography (TEG), with its real-time assessment, could offer an alternative to standard of care. This study aims to evaluate the use of TEG with traditional coagulation labs in the assessment of snake bite coagulopathy.Research Design: A retrospective review of patients who presented to a level 1 trauma center between 2014 and 2020 with snake bite envenomation was conducted, comparing traditional coagulation studies to TEG plus coagulation studies.Results: The 12 patients who had studies within the stipulations of our review were tracked and subsequently progressed well clinically with no adverse effects and ultimately discharged home with an average hospital stay of 2.2 days.Conclusions: Our data suggests that patients can be observed clinically without needing repeat coagulation studies if initial TEG and TCS are within normal limits.

Circuit change in neonatal and pediatric extracorporeal membrane oxygenation is associated with adverse outcomes.

INTRODUCTION: Extracorporeal membrane oxygenation (ECMO) circuits may be changed during the run for multiple reasons; however, these circuit changes may be associated with adverse events. Predictors for undergoing a circuit change (CC) and their outcomes remain unclear. We hypothesized that neonatal and pediatric CC correlates with increased morbidity and mortality. METHODS: Pediatric and neonatal patients who underwent one ECMO run lasting <30 days at a tertiary children's hospital from 2011 through 2017 were retrospectively reviewed. Bivariate regression analysis evaluated factors associated with ECMO mortality and morbidity. LASSO logistic regression models identified independent risk factors for undergoing a CC. p < .05 was significant. RESULTS: One hundred 85 patients were included; 137 (74%) underwent no CC, while 48 (26%) underwent one or more. Undergoing a CC was associated with longer ECMO duration (p < .001), higher blood transfusion volumes (p < .001), increased hemorrhagic complications (p < .001) and increased mortality (p = .002). Increased platelet (p = .001) and FFP (p = .016) transfusion volumes at any time while on ECMO were independent factors associated with undergoing a CC. CONCLUSIONS: Changing the circuit during the ECMO run occurs frequently and may be associated with poorer outcomes. Understanding the outcomes and predictors for CC may guide management protocols for more efficient circuit changes given its important association with overall outcomes.

Snake Envenomation Simulating ST Elevation Myocardial Infarction.

Envenomation syndromes following snakebites can include tissue reaction, coagulopathy, nephrotoxicity, and neurotoxicity. Cardiotoxicity is rare but usually presents with dysrhythmias. Myocardial infarction after envenomation has rarely been reported. We discuss a case of snake bite simulating ST-elevation myocardial infarction (STEMI). Our patient is a 49-year-old male who sustained a snake bite in his left hand. Patient had hemodynamic collapse requiring increasing pressor support; EKG and troponin results confirmed STEMI. Cardiac catheterization did not demonstrate any thrombosis, rather severe cardiomyopathy with left ventricular ejection fraction 20-25%. Even though our patient did not require any coronary intervention, an angiogram was warranted given the clinical presentation. Our case demonstrates severe cardiotoxicity following snake bite. Further research is warranted to study the mechanism behind such phenomena.

Splenic Rupture Following Colonoscopy.

Splenic rupture following colonoscopy (SRFC) is a rare complication and can have associated mortality if left undiagnosed. Most of the cases reported have been managed operatively. Here, we present a case of a 75-year-old-female who underwent conservative management for SRFC. Splenic rupture should remain a differential in patients presenting with abdominal pain, syncope, and hypotension following colonoscopy. Decisions regarding operative versus conservative management should be guided by the patient's clinical status, hemodynamics, and available resources.

Delayed Presentation of Small Bowel Injury Following Extraperitoneal Ballistic Injury.

Lack of peritoneal violation has been a strong tenet of nonoperative management for extraperitoneal penetrating injuries. There have been reports of intraperitoneal injuries without peritoneal violation in adult trauma literature. Such reports are scarce in pediatric trauma. We report delayed presentation of a small bowel injury in a 4-year-old male following extraperitoneal ballistic injury. No peritoneal violation was noted on wound exploration allowing conservative management. Patient developed abdominal distention on postoperative day 1, and radiologic imaging showed intraperitoneal air warranting an exploratory laparotomy. Intraperitoneal injuries without peritoneal violation have been attributed to the transmission of kinetic energy through the extraperitoneal tissue. Clinical judgment, physical exam, and radiologic adjuncts are of the utmost importance in management. Given our findings, extraperitoneal penetrating injuries certainly warrant extended observation of the patient.

Minimally Invasive Realignment for Slipping Rib Syndrome.

Slipping rib syndrome has remained a lesser-known entity despite its presence in the medical literature for over 100 years. If left undiagnosed, it can be associated with significant morbidity. Operative repair for the syndrome remains the definitive treatment. Traditional repair involved rib resection which can be technically challenging and have painful recovery. Minimal invasive techniques have been described recently which circumvent these issues. Here, we present our experience with our minimally invasive realignment technique for slipping rib syndrome. Our data suggested early hospital discharge, minimal perioperative complication, and near complete resolution of symptoms. We advocate for further research to enhance timely recognition and management for this entity and additionally recommend minimally invasive operative approach for definitive treatment.

The impact of social determinants of health on management of stage I non-small cell lung cancer.

BACKGROUND: Social Determinants of Health (SDOH) can be important contributors in health care outcomes. We hypothesized that certain SDOH independently impact the management and outcomes of stage I Non-Small Cell Lung Cancer (NSCLC). STUDY DESIGN: Patients with clinical stage I NSCLC were identified from the National Cancer Database. The impact of SDOH factors on utilization of surgery, perioperative outcomes and overall survival were examined, both in bivariate and multivariable analyses. RESULTS: A total of 236,140 patients were identified. In multivariate analysis, SDOH marginalization were associated with less frequent use of surgery, lower 5-year survival and, in surgical patients, more frequent use of open surgery and lower 90-day postoperative survival. CONCLUSION: SDOH disparities have a significant impact in the management and outcomes of stage I NSCLC. We identified SDOH patient groups particularly impacted by such disparities, in which higher utilization of surgery and minimally invasive approaches may lead to improved outcomes.

Bibliometric Analysis of the English Musculoskeletal Literature over the Last 30 Years.

Publication and authorship are important in academia for career advancement, obtaining grants, and improved patient care. There has been a recent interest in bibliometric changes over time, especially regarding the gender gap. The purpose of this study was to explore bibliometric changes in the musculoskeletal literature. Bibliometric variables (number of authors, institutions, countries, pages, references, corresponding author position, author gender, geographic region of origin, and editorial board makeup) were analyzed for 5 basic science and 12 clinically oriented musculoskeletal journals from 1985 through 2016. Statistical analyses comprised bivariate analyses, multifactorial ANOVAs, and logistic regression analyses. A p < 0.005 was considered significant. Nearly, all variables increased over time. Asia had the highest number of authors and corresponding author positions, Australia/New Zealand the highest number of institutions and references, North America the highest number of pages, and Europe the highest number of countries. Those with a female first author had more authors, institutions, countries, references, and pages. Likewise, those with a female corresponding author had more authors, institutions, countries, references, and pages. Single-authored manuscripts decreased over time. The percentage of female first authors rose from 10.8% in 1985-1987 to 23.7% in 2015-2016. There were more female 1st authors in the basic science journals compared to the clinical journals (33.2% vs. 12.7%). Single-authored manuscripts were more likely to be written by males (5.1 vs. 2.4%) and decreased over time. The many differences by geographic region of origin likely reflect different socio/cultural attitudes regarding academia and research, as well as the gender composition of the disciplines by geographic region. Overall, there has been an increase in the number of female 1st and corresponding authors, editorial board members, and chief editors, indicating a slow but progressive narrowing of the gender gap.

Bariatric surgery outcomes: is age just a number?

INTRODUCTION: Obesity and its associated comorbidities represent a pervasive problem in the United States across all age groups. There are conflicting data regarding the effectiveness and postoperative recovery of bariatric surgery in elderly patients. The aim of this study was to compare outcomes of bariatric surgery across age groups. MATERIALS AND METHODS: After obtaining institutional review board approval, patients with morbid obesity who underwent non-revisional laparoscopic Roux-en-Y gastric bypass (LRYGB) and sleeve gastrectomy (LSG) at our institution between 2011 and 2015 were included in this retrospective study. Patients were subdivided into five age groups: < 30, 30-39, 40-49, 50-59, and ≥ 60 years. Patient baseline demographics and comorbidities were collected. Postoperative outcomes including reinterventions/reoperations, 30-day-readmissions, 90-day-mortality, comorbidities' resolution, and change in BMI (ΔBMI) up to 4 years were recorded and compared. The groups were compared with ANOVA and chi-square tests and multivariable analyses. RESULTS: LRYGB was performed in 74.7% of the 1026 study patients. Patients ≥ 60 years old demonstrated lower preoperative BMI than patients < 50 years (p < 0.001). Patients 50-59 years old had increased length of stay compared to 30-39 (p = 0.003) and a higher prevalence of all comorbidities was found in older patients (p < 0.001). There was no significant difference in 30-day-readmissions; 90-day-mortality; reoperations; and reinterventions among the study groups. The ΔBMI was higher in younger patients and comorbidity resolution was more likely in younger patients with the exception of obstructive sleep apnea. CONCLUSION: Bariatric surgery can be accomplished safely across all age groups with satisfiable postoperative weight loss. However, older age had higher hospital stay and convalescence and lower comorbidity resolution compared to younger patients. Thus, bariatric surgery should be offered earlier in life to allow the patients to reap its benefits.

A Confirmed Case of Zoonotic Aortitis and Successful Repair with an Allograft.

INTRODUCTION: Streptococcus equi subspecies zooepidemicus is a ß-haemolytic group C streptococcus that is a highly contagious infection in horses and other equines. Streptococcus equi infection of the native human aorta is a rare form of aortitis that has a high mortality owing to rupture. Surgical intervention with debridement and broad spectrum intravenous antibiotics are essential to improve the patient's status. REPORT: In this case study, a 71 year old man with horse contact presented with left groin pain related to S. equi aortitis and mycotic aneurysm. He was successfully treated by excision of the infected abdominal aorta and iliac vessels with a biological graft reconstruction, debridement of the retroperitoneum, and application of antibiotic beads. DISCUSSION: Biological grafts have never been reportedly used in group C streptococcus infection of the native aorta, and the patient recovered without sequelae. The promising outcome of this case may provide a framework for future similar cases.

Financial Burden of Liver Transplant vs Resection for Hepatocellular Carcinoma.

BACKGROUND: Liver transplant and liver resection are surgical treatments for hepatocellular carcinoma (HCC) performed with curative intent. While liver transplant provides longer survival when compared to resection, the financial burden on patients and payors is significantly greater. With the increase in health care costs and the emergence of high deductible insurance policies that increase out of pocket deductibles for patients, assessment of value-based treatment is warranted. METHODS: We compiled total billable events from diagnosis of HCC through resection (N = 20) or transplant (N = 24) to death or last reported encounter from January 2011 to December 2012. RESULTS: Patients with HCC receiving resection had a model of end stage liver disease of 10.2 ± 1.2, survival 652 days (3-1, 167 days), and billable encounters of $316,873 ($2904/day). HCC patients receiving a liver transplant had a greater liver injury (model of end stage liver disease of 19.2 ± 3.7), longer survival (1579 days), and higher billable encounters, $740,714 ($2889/day). The surgical procedure represented the largest cost category (28% and 26% resection vs transplant, respectively). The cost effectiveness of treatment was directly proportional to length of survival. In resection, patients who survived >30 days (85%) cost per day dropped to $432. Transplant patients who survived >2 years (75%) saw the cost per day drop to $462. CONCLUSION: The relative financial burdens of liver resection vs liver transplant for treating HCC are comparable in patients who survive beyond a certain threshold. Transplant patients survived longer, and survival beyond 2 years makes this approach cost effective. In a health care climate aiming to contain costs and evaluate value-based treatment paradigms, expected survival and financial burden should be included in the treatment decision analysis.
