Obese adolescents have higher risk for femur fracture after motor vehicle collision.

Background: Previous reports identified an association between obese adolescents (OAs) and lower extremity (LE) fractures after blunt trauma. However, the type of LE fracture remains unclear. We hypothesized that OAs presenting after motor vehicle collision (MVC) have a higher risk of severe LE fracture and will require a longer length of stay (LOS) and more support services upon discharge, compared to non-OAs. Methods: The 2017-2019 Trauma Quality Improvement Program database was queried for adolescents (12-17-years-old) presenting after MVC. The primary outcome was LE fracture. A severe fracture was defined by abbreviated injury scale ≥3. OAs were defined by a body mass index (BMI) ≥30. Results: From 22,610 MVCs, 3325 (14.7 %) included OAs. The rate of any LE fracture was higher for OAs (21.6 % vs. 18.8 %, p < 0.001). On subset analysis the only LE fracture at higher risk in OAs was a femur fracture (13 % vs. 9.1 %, p < 0.001). After adjusting for sex and age, the risk for severe LE fracture (OR 1.34, CI 1.18-1.53, p < 0.001) was higher for OAs. OAs with a femur fracture had a longer median LOS (5 vs. 4 days, p = 0.003) and were more likely discharged with additional support services including home-health or inpatient rehabilitation (30.6 % vs. 21.4 %, p < 0.001). Conclusion: OAs sustaining MVCs have increased associated risk of femur fractures. OAs are more likely to have a higher-grade LE injury, experience a longer LOS, and require additional support services upon discharge. Future research is needed to determine if early disposition planning with social work assistance can help shorten LOS.

Impact of bariatric surgery on circulating irisin levels: a systematic review and meta­analysis.

This systematic review and meta-analysis evaluated changes in circulating irisin levels after bariatric surgery. A systematic search was performed across Embase, Scopus, PubMed, and Web of Science for this study. The meta-analysis was conducted using Comprehensive Meta-Analysis (CMA) V4 software. The overall effect size was depicted through a random-effects meta-analysis and the leave-one-out method. The meta-analysis, which included 13 studies with a total of 407 participants, showed a statistically non-significant reduction in circulating irisin levels following bariatric surgery (SMD: - 0.089, 95% CI - 0.281, 0.102, 95% PI: - 0.790, 0.611, p = 0.360; I2:70.56). Our research found no significant change in irisin levels after bariatric surgery. Moreover, these findings were not associated with the type of surgery or the duration of follow-up.

Prospective Outpatient Follow-Up of Early Cognitive Impairment in Patients with Mild Traumatic Brain Injury and Intracranial Hemorrhage.

INTRODUCTION: Mild traumatic brain injury (mTBI) encompasses a spectrum of disability including early cognitive impairment (ECI). The Brain Injury Guidelines (BIG) suggest mTBI patients can be safely discharged from the Emergency Department. Although half of mTBI patients with intracranial hemorrhage (ICH) have evidence of ECI, it is unclear what percentage of these patients' ECI persists after discharge. We hypothesize a significant proportion of trauma patients with mTBI and ECI at presentation have persistent ECI at 30-day follow-up. METHODS: A single-center prospective cohort study including adult trauma patients with ICH or skull fracture plus a Glasgow coma scale (GCS) of 13-15 on arrival was performed. Participants were screened for ECI using the Rancho Los Amigos Scale (RLA), and ECI was defined as a RLA < 8. We compared ECI and non-ECI groups for demographics, injury profile, computed tomography (CT) imaging (e.g., Rotterdam CT score) and outcomes with bivariate analysis. 30-day follow up phone calls were performed to re-evaluate RLA for persistent ECI and concussion symptoms. RESULTS: From 62 patients with ICH or skull fracture and mTBI, 21 (33.9%) had ECI. Patients with ECI had a higher incidence of subarachnoid hemorrhage (85.7% versus 46.3%, p=0.003) and higher Rotterdam CT score (p=0.004) compared to those without ECI. On 30-day follow up, 6 of 21 patients (26.6%) had persistent ECI. In addition, 7 (33.3%) patients had continued concussion symptoms. CONCLUSION: Over one-third of mTBI patients with ICH had ECI. At 30-day post-discharge follow-up over one-fourth of these patients had persistent ECI and 33% had concussion symptoms. This highlights the importance of identifying ECI prior to discharge as a significant portion may have ongoing difficulties reintegrating into work and society.

Bariatric Surgery Improves Serum CD40L Levels as a Predictor of Cardiovascular Risk: Systematic Review and Meta-analysis.

CD40 and its ligand have been recently implicated in the pathogenesis of cardiovascular disease (CVD). This meta-analysis examined the effect of bariatric surgery in reducing circulating CD40L levels. A systematic review was performed using Embase, Google Scholar, PubMed, Scopus, and Web of Science. The meta-analysis was provided by Comprehensive Meta-Analysis (CMA) V4 software. The overall effect size was detected by a random-effects meta-analysis and the leave-one-out approach. Random-effects meta-analysis of 7 studies including 191 subjects showed a significant reduction in CD40L after bariatric surgery (standardized mean difference (SMD), - 0.531; 95% CI, - 0.981, - 0.082; p = 0.021; I2, 87.00). Circulating levels of CD40L are decreased after bariatric surgery which may represent a mechanism for improvement of metabolic profile.

Comparing Accuracy of Night Radiology Interpretations for Pediatric Trauma: Radiology Residents Versus Attending Teleradiologists.

Background: Overnight radiology coverage for pediatric trauma patients (PTPs) is addressed with a combination of on-call radiology residents (RRs) and/or attending teleradiologists (ATs); however, the accuracy of these two groups has not been investigated for PTPs. We aimed to compare the accuracy of RRs vs AT interpretations of computed tomography (CT) scans for PTPs. Methods: Pediatric trauma patients (<18 years old) at a single level-I adult/level-II pediatric trauma center were studied in a retrospective analysis (3/2019-5/2020). Computed tomography scans interpreted by both RRs and ATs were included. Radiology residents were compared to ATs for time to interpretation (TTI) and accuracy compared to faculty attending radiologist interpretation, using the validated RADPEER scoring system. Additionally, RR and AT accuracies were compared to a previously studied adult cohort during the same time-period. Results: 42 PTPs (270 interpretations) and 1053 adults (8226 interpretations) were included. Radiology residents had similar rates of discrepancy (13.3% vs 13.3%), major discrepancy (4.4% vs 4.4%), missed findings (9.6% vs 12.6%), and overcalls (3.7% vs .7%) vs ATs (all P > .05). Mean TTI was shorter for RRs (55.9 vs 90.4 minutes, P < .001). Radiology residents had a higher discrepancy rate for PTPs (13.3% vs 7.5%, P = .01) than adults. Attending teleradiologists had a similar discrepancy rate for PTPs and adults (13.3% vs 8.9%, P = .07). Discussion: When interpreting PTP CT imaging, RRs had similar discrepancy rates but faster TTI than ATs. Radiology residents had a higher discrepancy rate for PTP CTs than RR interpretation of adult patients, indicating both RRs and ATs need more focused training in the interpretation of PTP studies.

Correlation of the Endoscopic Gastroesophageal Flap Valve with Pathologic Reflux.

BACKGROUND: The Hill classification characterizes the geometry of gastroesophageal junction and Hill grades (HGs) III and IV have a high association with pathologic reflux. This study aimed to understand the use of the Hill classification and correlate the prevalence of pathologic reflux across different HGs. STUDY DESIGN: A retrospective review of 477 patients who underwent upper endoscopy and BRAVO pH monitoring between August 2018 and October 2021 was performed. These charts were reviewed for endoscopic findings for hiatal hernia and association of HGs with pathologic reflux, defined as an abnormal esophageal acid exposure time (AET) of ≥4.9%. RESULTS: Of 477 patients, 252 (52.8%) had an HG documented on the endoscopy report. Of the 252 patients, 61 had HG I (24.2%), 100 had HG II (39.7%), 61 had HG III (24.2%), and 30 had HG IV (11.9%). The proportion of patients with abnormal AET increases with increasing HGs (p < 0.001) as follows: I (39.3%), II (52.5%), III (67.2%), and IV (79.3%). The mean overall AET is as follows: HG I (5.5 ± 6%), HG II (7.0 ± 5.9%), HG III (10.2 ± 10.3%), and HG IV (9.5 ± 5.5%). The proportion of patients with hiatal hernia was 18% for HG I, 28% for HG II, 39.3% for HG III, and 80% for HG IV. CONCLUSIONS: Use of the Hill classification in clinical practice is low. There is an association of increasing HGs with increasing proportion of patients with abnormal AET. There is a high proportion of patients within HGs I and II with documented pathologic reflux and the presence of a hiatal hernia as observed on endoscopic examination. Our study suggests that endoscopic grading of the gastroesophageal junction may not adequately differentiate between normal vs abnormal reflux status, particularly for HGs I and II.

Outcomes of Colectomy and Proctectomy According to Surgeon Training: General vs Colorectal Surgeons.

BACKGROUND: Colectomies and proctectomies are commonly performed by both general surgeons (GS) and colorectal surgeons (CRS). The aim of our study was to examine the outcomes of elective colectomy, urgent colectomy, and elective proctectomy according to surgeon training. STUDY DESIGN: Data were obtained from the Vizient database for adults who underwent elective colectomy, urgent colectomy, and elective proctectomy from 2020 to 2022. Operations performed in the setting of trauma and patients within the database's highest relative expected mortality risk group were excluded. Outcomes were compared according to surgeon's specialty: GS vs CRS. The primary outcome was in-hospital mortality. The secondary outcome was in-hospital complication rate. Data were analyzed using multivariate logistic regression. RESULTS: Of 149,516 elective colectomies, 75,711 (50.6%) were performed by GS and 73,805 (49.4%) by CRS. Compared with elective colectomies performed by CRS, elective colectomies performed by GS had higher rates of complications (4.9% vs 3.9%, odds ratio [OR] 1.23, 95% CI 1.17 to 1.29, p < 0.01) and mortality (0.5% vs 0.2%, OR 2.06, 95% CI 1.72 to 2.47, p < 0.01). Of 71,718 urgent colectomies, 54,680 (76.2%) were performed by GS, whereas 17,038 (23.8%) were performed by CRS. Compared with urgent colectomies performed by CRS, urgent colectomies performed by GS were associated with higher rates of complications (12.1% vs 10.4%, OR 1.14, 95% CI 1.08 to 1.20, p < 0.01) and mortality (5.1% vs 2.3%, OR 2.08, 95% CI 1.93 to 2.23, p < 0.01). Of 43,749 elective proctectomies, 28,458 (65.0%) were performed by CRS and 15,291 (35.0%) by GS. Compared with proctectomies performed by CRS, those performed by GS were associated with higher rates of complications (5.3% vs 4.4%, OR 1.16, 95% CI 1.06 to 1.27, p < 0.01) and mortality (0.3% vs 0.2%, OR 1.49, 95% CI 1.02 to 2.20, p = 0.04). CONCLUSIONS: In this nationwide study, colectomies and proctectomies performed by CRS were associated with improved outcomes compared with GS. Hospitals without a CRS on staff should consider prioritizing recruiting CRS specialists.

Domestic firearm violence against women (2018-2021).

Background: Over 50 % of US female homicides occur during domestic violence, with half involving firearms. Public health measures to control COVID-19 may have isolated individuals with abusive partners at a time when firearm sales and new firearm ownership surged. This study sought to evaluate trends in domestic firearm violence (DFV) over time, hypothesizing that rates of DFV increased in the wake of COVID-19. Materials and methods: A retrospective query of the Gun Violence Archive (2018-2021) was conducted for incidents of DFV. The primary outcome was the number of DFV-related shootings. Statistical testing, including one-way and two-way ANOVAs, was performed to compare monthly rates of DFV over time and to compare DFV per 100,000 women in states with strong versus weak gun laws. Results: Average monthly DFV incidents rose nationwide during this study's time period, though injuries and fatalities did not. States with weaker gun laws had increased incidents, deaths, and injuries from 2018 to 2021 (all p<0.05). In a two-way ANOVA, stronger gun laws were associated with fewer incidents of DFV when compared with weaker gun law states. We also found that the use of a long gun in DFV more often resulted in a victim's death when compared to a handgun (p<0.01). Conclusion: DFV incidents increased over time. States with weaker gun laws bore the brunt of the violence, demonstrating that DFV may be curtailed through legislative efforts. Methods of injury prevention aimed at preventing and reducing domestic violence and improving firearm safety may curtail DFV.

Improvement of Triglyceride-Glucose Index Following Bariatric Surgery: a Systematic Review and Meta-analysis.

BACKGROUND: Bariatric surgery is an effective intervention for the management of severe obesity and its associated comorbidities, including metabolic abnormalities. This meta-analysis aimed to evaluate the impact of bariatric surgery on the triglyceride-glucose (TyG) index, a novel marker of insulin resistance and metabolic syndrome. METHODS: A systematic search was conducted in Embase, PubMed, Web of Science, and Scopus. The meta-analysis was performed using Comprehensive Meta-Analysis (CMA) V4 software. The overall effect size was determined by a random-effects meta-analysis and the leave-one-out approach. RESULTS: A total of 9 trials including 1620 individuals confirmed a significant reduction in TyG following bariatric surgery (weighted mean difference (WMD) - 0.770, 95% CI - 1.006, - 0.534, p < 0.001). In a sub-analysis according to the type of bariatric surgery there was a significant reduction in TyG index for Roux-en-Y gastric bypass (WMD - 0.775, 95% CI - 1.000, - 0.550, p < 0.001), and sleeve gastrectomy (WMD - 0.920, 95% CI - 1.368, - 0.473, p < 0.001). In a sub-analysis according to the follow-up duration there was similarly a significant reduction in TyG index for both < 12 months (WMD - 1.645, 95% CI - 2.123, - 1.167, p < 0.001), and ≥ 12 months follow-up (WMD - 0.954, 95% CI - 1.606, - 0.303, p < 0.001). CONCLUSION: The results of this meta-analysis demonstrated a significant reduction in the TyG index following bariatric surgery, indicating improved insulin sensitivity and metabolic health. These findings highlight the potential of bariatric surgery as a valuable therapeutic option for individuals with obesity and its metabolic consequences.

Development of an adaptive test of musical scene analysis abilities for normal-hearing and hearing-impaired listeners.

Auditory scene analysis (ASA) is the process through which the auditory system makes sense of complex acoustic environments by organising sound mixtures into meaningful events and streams. Although music psychology has acknowledged the fundamental role of ASA in shaping music perception, no efficient test to quantify listeners' ASA abilities in realistic musical scenarios has yet been published. This study presents a new tool for testing ASA abilities in the context of music, suitable for both normal-hearing (NH) and hearing-impaired (HI) individuals: the adaptive Musical Scene Analysis (MSA) test. The test uses a simple 'yes-no' task paradigm to determine whether the sound from a single target instrument is heard in a mixture of popular music. During the online calibration phase, 525 NH and 131 HI listeners were recruited. The level ratio between the target instrument and the mixture, choice of target instrument, and number of instruments in the mixture were found to be important factors affecting item difficulty, whereas the influence of the stereo width (induced by inter-aural level differences) only had a minor effect. Based on a Bayesian logistic mixed-effects model, an adaptive version of the MSA test was developed. In a subsequent validation experiment with 74 listeners (20 HI), MSA scores showed acceptable test-retest reliability and moderate correlations with other music-related tests, pure-tone-average audiograms, age, musical sophistication, and working memory capacities. The MSA test is a user-friendly and efficient open-source tool for evaluating musical ASA abilities and is suitable for profiling the effects of hearing impairment on music perception.

Open vs robotic gastrectomy with D2 lymphadenectomy: a propensity score-matched analysis on 1469 patients from the IMIGASTRIC prospective database.

BACKGROUND: Comparative data on D2-robotic gastrectomy (RG) vs D2-open gastrectomy (OG) are lacking in the Literature. Aim of this paper is to compare RG to OG with a focus on D2-lymphadenectomy. STUDY DESIGN: Data of patients undergoing D2-OG or RG for gastric cancer were retrieved from the international IMIGASTRIC prospective database and compared. RESULTS: A total of 1469 patients were selected for inclusion in the study. After 1:1 propensity score matching, a total of 580 patients were matched and included in the final analysis, 290 in each group, RG vs OG. RG had longer operation time (210 vs 330 min, p < 0.0001), reduced intraoperative blood loss (155 vs 119.7 ml, p < 0.0001), time to liquid diet (4.4 vs 3 days, p < 0.0001) and to peristalsis (2.4 vs 2 days, p < 0.0001), and length of postoperative stay (11 vs 8 days, p < 0.0001). Morbidity rate was higher in OG (24.1% vs 16.2%, p = 0.017). CONCLUSION: RG significantly expedites recovery and reduces the risk of complications compared to OG. However, long-term survival is similar.

Obese adolescents have higher risk for severe lower extremity fractures after falling.

INTRODUCTION: Reports vary on the impact of obesity on the incidence of lower extremity fractures after a fall. We hypothesized that obese adolescents (OA) presenting after a fall have a higher risk of any and severe lower extremity fractures compared to non-OAs. METHODS: A national database was queried for adolescents (12-17 years old) after a fall. Primary outcome included lower extremity fracture. Adolescents with a body mass index (BMI) ≥ 30 (OA) were compared to adolescents with a BMI < 30 (non-OA). RESULTS: From 20,264 falls, 2523 (12.5%) included OAs. Compared to non-OAs, the rate of any lower extremity fracture was higher for OAs (51.5% vs. 30.7%, p < 0.001). This remained true for lower extremity fractures at all locations (all p < 0.05). After adjusting for sex and age, associated risk for any lower extremity fracture (OR 2.41, CI 2.22-2.63, p < 0.001) and severe lower extremity fracture (OR 1.31, CI 1.15-1.49, p < 0.001) was higher for OAs. This remained true in subset analyses of ground level falls (GLF) and falls from height (FFH) (all p < 0.05). CONCLUSIONS: Obesity significantly impacts adolescents' risk of all types of lower extremity fractures after FFH or GLF. Hence, providers should have heightened awareness for possible lower extremity fractures in OAs. LEVEL OF EVIDENCE: IV.

Analysis of Veno-Venous Extracorporeal Membrane Oxygenation for COVID-19 Compared to Non-COVID Etiologies.

OBJECTIVE: This study analyzed the characteristics and outcomes of veno-venous (V-V) extracorporeal membrane oxygenation (ECMO) for acute respiratory distress syndrome (ARDS) due to COVID-19 versus non-COVID causes at US academic centers. BACKGROUND DATA: V-V ECMO support has been utilized for COVID-19 patients with ARDS since the beginning of the pandemic. Mortality for ECMO in COVID-19 has been reported to be high but similar to reported mortality for ECMO support for non-COVID causes of respiratory failure. METHODS: Using ICD-10 codes, data of patients who underwent V-V ECMO for COVID-19 ARDS were compared with patients who underwent V-V ECMO for non-COVID causes between April 2020 and December 2022. The primary outcome was in-hospital mortality. Secondary outcome measures included length of stay and direct cost. Multivariate logistic regression modeling was performed to analyze differences in mortality between COVID and non-COVID groups, adjusting for other important risk factors (age, sex, and race/ethnicity). RESULTS: We identified and compared 6382 patients who underwent V-V ECMO for non-COVID causes to 6040 patients who underwent V-V ECMO for COVID-19. There was a significantly higher proportion of patients aged ≥ 65 years who underwent V-V ECMO in the non-COVID group compared with the COVID group (19.8% vs. 3.7%, respectively, P <0.001). Compared with patients who underwent V-V ECMO for non-COVID causes, patients who underwent V-V ECMO for COVID had increased in-hospital mortality (47.6% vs. 34.5%, P <0.001), length of stay (46.5±41.1 days vs. 40.6±46.1, P <0.001), and direct hospitalization cost ($207,022±$208,842 vs. $198,508±205,510, P =0.02). Compared with the non-COVID group, the adjusted odds ratio (OR) for in-hospital mortality in the COVID group was 2.03 (95% CI: 1.87-2.20, P <0.001). In-hospital mortality for V-V ECMO in COVID-19 improved during the study time period (50.3% in 2020, 48.6% in 2021, and 37.3% in 2022). However, there was a precipitous drop in the ECMO case volume for COVID starting in quarter 2 of 2022. CONCLUSIONS: In this nationwide analysis, COVID-19 patients with ARDS requiring V-V ECMO support had increased mortality compared with patients who underwent V-V ECMO for non-COVID etiologies.

Impact of COVID-19 Pandemic on Management and Outcomes of Acute Cholecystitis at US Academic Centers.

BACKGROUND: The COVID-19 pandemic has had wide-ranging effects on management of medical conditions. Many hospitals encountered staffing shortages, limited operating room availability, and shortage of hospital beds. There was increased psychological stress and fear of contracting COVID-19 infection, leading to delay in medical care for various disease processes. The objective of this study was to examine changes in management and outcomes attributed to the COVID-19 pandemic in patients presenting with acute calculus cholecystitis at US academic centers. STUDY DESIGN: Using the Vizient database, patients with the diagnosis of acute calculus cholecystitis who underwent intervention during the 15 months before the pandemic (prepandemic, October 2018 to December 2019) were compared with 15 months during the pandemic (pandemic, March 2020 to May 2021). Outcomes measures included demographics, characteristics, type of intervention, length of stay, in-hospital mortality, and direct cost. RESULTS: There were 146,459 patients with acute calculus cholecystitis identified (prepandemic: 74,605 vs pandemic: 71,854). Patients in the pandemic group were more likely to undergo medical management (29.4% vs 31.8%; p < 0.001) or percutaneous cholecystostomy tube placement (21.5% vs 18%; p < 0.001) and less likely to undergo laparoscopic cholecystectomy (69.8% vs 73.0%; p < 0.001). Patients in the pandemic group who underwent procedural intervention had longer length of stay (6.5 days vs 5.9 days; p < 0.001), higher in-hospital death (3.1% vs 2.3%; p < 0.001), and higher cost ($14,609 vs $12,570; p < 0.001). CONCLUSIONS: In this analysis of patients with acute calculus cholecystitis, there were distinct changes in the management and outcomes of patients due to the COVID-19 pandemic. Changes in the type of intervention and outcomes are likely related to delayed presentation with increases in the severity and complexity of the disease.

Reducing SDG complexity and informing environmental management education via an empirical six-dimensional model of sustainable development.

Effective environmental management higher education programs are essential for achieving the Sustainable Development Goals (SDGs). Yet SDG complexity means many educators focus on environment and avoid critical but challenging social, economic and governance aspects. This undermines the calls for comprehensive environmental management education that effectively integrates all key sustainability dimensions. Various sustainability models, mostly founded on the pillars of sustainability, have consequently evolved. They are generally conceptual and/or involve subjective categorization of the SDGs, which has led to demands for more empirically based models. This study has consequently used a mixed-method approach to model Australian university students' SDG perceptions. The qualitative research identified three items (on average) for each SDG, and a quantitative survey then measured their perceived importance. Factor analysis generated a robust six-dimensional sustainable development model comprised of 37 SDG items, which validates environment and governance aspects of some traditional pillar-based sustainability models. It has also uncovered new social and economic dimensions: social harmony and equality; sustainable consumption and socioeconomic behaviors; sustainable production, industry and infrastructure; and acute poverty reduction. These findings can help educators, organizations and citizens to categorize and integrate SDGs via better understanding of their key dimensions and impacts.

Readmission and Disposition in Patients With Malignant Bowel Obstructions Following Gastrostomy Tube.

BACKGROUND: Patients with peritoneal carcinomatosis (PC) can develop malignant bowel obstructions (MBOs) requiring inpatient admission and nasogastric tube decompression. Palliative decompressive gastrostomy tubes (G-tubes) may affect patient disposition, allowing for self-management and reduction in inpatient services. Therefore, we sought to assess disposition and inpatient readmission rates in patients admitted with PC and MBO following G-tube placement. METHODS: The Vizient® Clinical Data Base was queried for inpatient admissions from October 2018 to May 2022 utilizing ICD-10 codes to identify patients admitted with PC and bowel obstruction, with or without G-tube placement. Demographics and hospital outcomes were recorded. Descriptive statistics and multivariate logistic regression analysis were performed. RESULTS: From 750 patients, 59 (7.9%) had a G-tube placed. Compared to patients without G-tubes, those with G-tubes had lower rates of disposition to home (32.2% vs 70.0%, P < .001) and higher rates of disposition to hospice (home: 30.5% vs 7.8%, P < .001, facility: 10.2% vs 3.9%, P = .02). There was no significant difference in the rate (17.3% vs 22.3%, P = .40) or risk (OR = 1.44, 95% CI .69-3.01) of 30-day readmissions with G-tubes. However, palliative care consultation (OR 33.77, 95% CI 19.16-59.52) and G-tube placement (OR 5.82, 95% CI 2.56-13.25) were independent predictors for hospice. DISCUSSION: Placement of G-tubes in patients with PC and MBO was associated with higher rates of disposition to hospice but there is no difference in 30-day readmission rates compared to those without G-tubes. Further prospective studies are needed to understand the role of G-tube placement in patients with MBO in relation to outcomes and disposition.

Trends in mass shootings in the United States (2013-2021): A worsening American epidemic of death.

BACKGROUND: Mass shootings represent a significant problem in the United States (US). This study aimed to examine trends in mass shootings in the US over time. METHODS: Retrospective mass shooting data (1/2013-12/2021) were collected from the Gun Violence Archive. A scatterplot was constructed showing predicted (extrapolated from 2013 to 2019) versus actual total mass shootings in 2020 and 2021. Multivariate linear regressions were performed to evaluate trends in mass shootings over time, associated with gun law strength. RESULTS: Mass shooting incidents, injuries, and deaths in 2020 and 2021 exceeded extrapolations from previous years. When comparing 2019 to 2020, stronger gun laws were associated with decreased monthly mass shooting deaths. For these same strong gun law states, monthly mass shooting deaths decreased when comparing 2019 to 2021 and comparing 2020 to 2021. CONCLUSIONS: US mass shootings have increased over the past decade. Stronger gun laws appear associated with fewer monthly mass shooting-related deaths. Firearm-related legislation may at least partially, curtail the worsening of this substantial "American problem" of mass shootings.

Effectiveness on post-stroke hemiplegia in patients: electroacupuncture plus cycling electroacupuncture alone.

OBJECTIVE: To evaluate the effectiveness of cycling in combination with electroacupuncture in treatment of post-stroke hemiplegia patients at National Hospital of Acupuncture, Vietnam. METHODS: The study was designed as a single-centre, outcome-assessor-blinded parallel randomised controlled trial with 120 post-stroke hemiplegia patients randomly assigned into two groups: electroacupuncture plus cycling (CT group) and electroacupuncture (AT group). Patients were assessed before and after the treatment (using muscle grading, modified Rankin, Barthel, Orgorozo scores and electromyography). Statistical Man-Whitney U test, and Fisher's exact tests were used to compare between CT and AT groups. RESULTS: The results reported statistically significant improvement in motor function in patients suffering from hemiplegia following ischemic stroke in both CT and AT groups. Patients in CT group experienced a greater improvement compared to those in AT group including better muscle contraction (increased frequency and amplitude of electromyography and increased muscle grading scale); increased recovery (Orgogozo scale), increased independency (Barthel scale) and decreased disability (Modified Rankin scale) (< 0.01). CONCLUSIONS: Combination with cycling training significantly improves the recovery of post-stroke patients treated with electroacupuncture.

Development and Validation of a Renal Replacement after Trauma Scoring Tool.

BACKGROUND: Stress on the healthcare system requires careful allocation of resources such as renal replacement therapy (RRT). The COVID-19 pandemic generated difficulty securing access to RRT for trauma patients. We sought to develop a renal replacement after trauma (RAT) scoring tool to help identify trauma patients who may require RRT during their hospitalization. STUDY DESIGN: The 2017 to 2020 TQIP database was divided into a derivation (2017 to 2018 data) and validation (2019 to 2020 data) set. A 3-step methodology was used. Adult trauma patients admitted from the emergency department to the operating room or ICU were included. Patients with chronic kidney disease, transfers from another hospital, and emergency department death were excluded. Multiple logistic regression models were created to determine the risk for RRT in trauma patients. The weighted average and relative impact of each independent predictor was used to derive a RAT score, which was validated using area under receiver operating characteristic curve (AUROC). RESULTS: From 398,873 patients in the derivation and 409,037 patients in the validation set, 11 independent predictors of RRT were included in the RAT score derived with scores ranging from 0 to 11. The AUROC for the derivation set was 0.85. The rate of RRT increased to 1.1%, 3.3%, and 20% at scores of 6, 8, and 10, respectively. The validation set AUROC was 0.83. CONCLUSIONS: RAT is a novel and validated scoring tool to help predict the need for RRT in trauma patients. With future improvements including baseline renal function and other variables, the RAT tool may help prepare for the allocation of RRT machines/staff during times of limited resources.
