Primary Repair Versus Resection for AAST Grade I and II Colon Injuries: Does the Type of Repair Matter?

INTRODUCTION: The management of traumatic colon injuries has evolved over the past two decades. Recent evidence suggests that primary repair or resection over colostomy may decrease morbidity and mortality. Data comparing patients undergoing primary repair versus resection are lacking. We sought to compare the outcomes of patients undergoing primary repair versus resection for low-grade colon injuries. METHODS: A retrospective review of all patients who presented with American Association for the Surgery of Trauma grade I and II traumatic colon injuries to our Level I trauma center between 2011 and 2021 was performed. Patients were further dichotomized based on whether they underwent primary repair or resection with anastomosis. Outcome measures included length of stay data, infectious complications, and mortality. RESULTS: A total of 120 patients met inclusion criteria. The majority of patients (76.7%) were male, and the average age was 35.6 ± 13.1 y. Most patients also underwent primary repair (80.8%). There were no statistically significant differences between the groups in arrival physiology or in injury severity score. Length of stay data including hospital length of stay, intensive care unit length of stay, and ventilator days were similar between groups. Postoperative complications including pneumonia, surgical site infections, fascial dehiscence, the development of enterocutaneous fistulas, and unplanned returns to the operating room were also all found to be similar between groups. The group who underwent resection with anastomosis did demonstrate a higher rate of intra-abdominal abscess development (3.1% versus 26.1%, P < 0001). Mortality between both groups was not found to be statistically significant (7.2% versus 4.3%, P = 0.4) CONCLUSIONS: For low-grade (American Association for the Surgery of Trauma I and II) traumatic colon injuries, patients undergoing primary repair demonstrated a decreased rate of intra-abdominal abscess development when compared to patients who underwent resection with anastomosis.

Seraph 100 Microbind Affinity Blood Filter Does Not Clear Antibiotics: An Analysis of Antibiotic Concentration Data from PURIFY-OBS.

INTRODUCTION: Novel hemoperfusion systems are emerging for the treatment of sepsis. These devices can directly remove pathogens, pathogen-associated molecular patterns, cytokines, and other inflammatory markers from circulation. However, significant safety concerns such as potential antibiotic clearance need to be addressed prior to these devices being used in large clinical studies. METHODS: Prospective, observational study of 34 participants undergoing treatment with the Seraph 100® Microbind Affinity Blood Filter (Seraph 100) device at 6 participating sites in the USA. Patients were included for analysis if they had a record of receiving an antibiotic concurrent with Seraph 100 treatment. Patients were excluded if there was missing information for blood flow rate. Blood samples were drawn pre- and post-filter at 1 h and 4 h after treatment initiation. These average pre- and post-filter time-concentration observations were then used to estimate antibiotic clearance in L/h (CLSeraph) due to the Seraph 100 device. RESULTS: Of the 34 participants in the study, 17 met inclusion and exclusion criteria for the antibiotic analysis. Data were obtained for 7 antibiotics (azithromycin, cefazolin, cefepime, ceftriaxone, linezolid, piperacillin, and vancomycin) and one beta-lactamase inhibitor. Mean CLSeraph for the antibiotics investigated ranged from -0.57 to 0.47 L/h. No antibiotic had a CLSeraph statistically significant from 0. DISCUSSION/CONCLUSION: The Seraph 100 did not significantly clear any measured antibiotic in clinical samples. These data give further evidence to suggest that these therapies may be safely administered to critically ill patients and will not impact concentrations of administered antibiotics.

Complications following arthroscopic Bankart repair: a systematic review.

BACKGROUND: Complications are rare after arthroscopic Bankart repair, and as a result, there is a lack of guidance over rates of complications that can be used to consent patients. The purpose of this study is to systematically review the literature to assess the complications after arthroscopic Bankart repair, other than recurrent instability. METHODS: A literature search of MEDLINE, Embase, and the Cochrane Library was performed based on the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines. Clinical studies reporting on the complications after arthroscopic Bankart repair were included. RESULTS: A total of 194 studies were included in the analysis, with 13,979 patients and 14,019 shoulders undergoing arthroscopic Bankart repair. The overall complication rate was 0.67%, with frozen shoulder being the most common complication occurring in 0.32%. Persistent pain occurred in 0.17%. The rates of nerve, hardware, and wound complications were 0.07%, 0.05%, and 0.03%, respectively. CONCLUSION: The arthroscopic Bankart repair has a very low rate of complications. Frozen shoulder and persistent pain are the most frequently encountered complications.

Burn and Trauma Burden and Screening for Interpersonal Violence During the COVID-19 Pandemic.

INTRODUCTION: Nationwide shelter-in-place (SIP) orders during the pandemic have had long-lasting effects, including increased rates of domestic violence and interpersonal violence. Screening for violence varies by institution, which tool is used, and when. Given increases in burn and trauma admissions over the course of the pandemic, we sought to examine trends at our institution during this time period to better guide care and anticipate system-level effects. METHODS: We performed a retrospective cohort study of pediatric burn and adult burn and trauma patients at our level 1 trauma/burn center between March-May 2019 and March-May 2020. Home safety screening was performed by nursing staff using a 1-part screening questionnaire. Patients presenting before March 15, 2020, were defined as "pre-SIP; " between March 16-May 19, 2020, were "during SIP; " and those after May 19, 2020, were designated as "post-SIP." Descriptive and chi-square statistics were used. Demographic, injury patterns, and screening information were collected. RESULTS: Blunt trauma comprised 60% of injuries, followed by burns (30%) then penetrating injury (7%). Over the entire time period analyzed, 1822 patients had documented home safety screening; ∼2% of patients screened reported a safety concern pre-SIP, compared to 3% of patients during SIP. There were higher rates of burns and penetrating injury during SIP compared to other periods (P ≤ 0.0001). Home safety screening rates were 94%-95% pre- and during SIP, but dropped to 85% post-SIP (P < 0.0001). Home safety concerns were reported almost 2% of the time pre-SIP and 3% during SIP (P = 0.016). CONCLUSIONS: We noted an increase in trauma and burns during and after SIP orders, consistent with the experiences of other institutions. Implementation of a nurse-driven screening process demonstrated high compliance with appropriate referrals. The burden of burn and traumatic injury remains significant, highlighting a need for continued psychosocial screening and the provision of psychosocial support resources in the acute trauma setting.

Relationship between impaired myocardial blood flow by positron emission tomography and low-attenuation plaque burden and pericoronary adipose tissue attenuation from coronary computed tomography: From the prospective PACIFIC trial.

BACKGROUND: Positron emission tomography (PET) is the clinical gold standard for quantifying myocardial blood flow (MBF). Pericoronary adipose tissue (PCAT) attenuation may detect vascular inflammation indirectly. We examined the relationship between MBF by PET and plaque burden and PCAT on coronary CT angiography (CCTA). METHODS: This post hoc analysis of the PACIFIC trial included 208 patients with suspected coronary artery disease (CAD) who underwent [15O]H2O PET and CCTA. Low-attenuation plaque (LAP, < 30HU), non-calcified plaque (NCP), and PCAT attenuation were measured by CCTA. RESULTS: In 582 vessels, 211 (36.3%) had impaired per-vessel hyperemic MBF (≤ 2.30 mL/min/g). In multivariable analysis, LAP burden was independently and consistently associated with impaired hyperemic MBF (P = 0.016); over NCP burden (P = 0.997). Addition of LAP burden improved predictive performance for impaired hyperemic MBF from a model with CAD severity and calcified plaque burden (P < 0.001). There was no correlation between PCAT attenuation and hyperemic MBF (r = - 0.11), and PCAT attenuation was not associated with impaired hyperemic MBF in univariable or multivariable analysis of all vessels (P > 0.1). CONCLUSION: In patients with stable CAD, LAP burden was independently associated with impaired hyperemic MBF and a stronger predictor of impaired hyperemic MBF than NCP burden. There was no association between PCAT attenuation and hyperemic MBF.

Immunotherapy for keratinocyte cancers. Part I: Immune-related epidemiology, risk factors, pathogenesis, and immunotherapy management of keratinocyte cancers.

The important role of the immune system in the surveillance and control of keratinocyte cancers (KCs), namely squamous and basal cell carcinomas, is increasingly appreciated, as new immunotherapies have recently become available. As the field of immunotherapy is rapidly evolving, this review synthesizes key concepts and highlights important cellular components within the immune system responsible for attacking KCs. We review the most current data on the epidemiology, risk factors, and immunotherapy management for KCs. Patients will seek advice from dermatologists to help explain why immunotherapies work for KCs and whether they might be appropriate for different clinical scenarios. Collaboration with medical colleagues across different disciplines to evaluate KCs for response to immunotherapy and early recognition of immune-related adverse events will help to optimize patient outcomes.

Evaluation of Online Artificial Intelligence-Generated Information on Common Hand Procedures.

PURPOSE: The purpose of this study was to analyze the quality and readability of the information generated by an online artificial intelligence (AI) platform regarding 4 common hand surgeries and to compare AI-generated responses to those provided in the informational articles published by the American Society for Surgery of the Hand (ASSH) HandCare website. METHODS: An open AI model (ChatGPT) was used to answer questions commonly asked by patients on 4 common hand surgeries (carpal tunnel release, cubital tunnel release, trigger finger release, and distal radius fracture fixation). These answers were evaluated for medical accuracy, quality and readability and compared to answers derived from the ASSH HandCare materials. RESULTS: For the AI model, the Journal of the American Medical Association benchmark criteria score was 0/4, and the DISCERN score was 58 (considered good). The areas in which the AI model lost points were primarily related to the lack of attribution, reliability and currency of the source material. For AI responses, the mean Flesch Kinkaid Reading Ease score was 15, and the Flesch Kinkaid Grade Level was 34, which is considered to be college level. For comparison, ASSH HandCare materials scored 3/4 on the Journal of the American Medical Association Benchmark, 71 on DISCERN (excellent), 9 on Flesch Kinkaid Grade Level, and 60 on Flesch Kinkaid Reading Ease score (eighth/ninth grade level). CONCLUSION: An AI language model (ChatGPT) provided generally high-quality answers to frequently asked questions relating to the common hand procedures queried, but it is unclear when or where these answers came from without citations to source material. Furthermore, a high reading level was required to comprehend the information presented. The AI software repeatedly referenced the need to discuss these questions with a surgeon, the importance of shared decision-making and individualized care, and compliance with surgeon treatment recommendations. CLINICAL RELEVANCE: As novel AI applications become increasingly mainstream, hand surgeons must understand the limitations and ramifications these technologies have for patient care.

Pyrocarbon hemiarthroplasty of the shoulder: a systematic review and meta-analysis of clinical results.

BACKGROUND: Hemiarthroplasty is often considered in the setting of preserved glenoid cartilage given the high risk of revision associated with total shoulder arthroplasty. Pyrocarbon (PyC) has been used as an implant material that theoretically allows for formation of a neo-membrane that would act like cartilage to reduce glenoid wear. The purpose of this study was to evaluate the clinical outcomes, radiographic outcomes, revision rates, and complication rates in the existing literature on shoulder hemiarthroplasty using PyC. METHODS: The MEDLINE, Embase, and Scopus databases were searched for articles relating to shoulder hemiarthroplasty using the terms "pyrocarbon" or "pyrolytic carbon." Abstracts and articles were screened against predefined inclusion and exclusion criteria, with a minimum of 24 months' follow-up required. Data on patient demographic characteristics, clinical outcome scores, complications, revision rates, and radiographic findings were recorded. Where appropriate, meta-analysis was performed. RESULTS: Twelve studies were selected for final inclusion, with a total of 536 patients. Among the studies reporting preoperative and postoperative range of motion (ROM), an overall improvement in ROM was observed. The mean Constant score was 70.9 points postoperatively, with a mean improvement of 36.2 points (n = 359, 9 studies). Radiographically, 22.8% of patients (n = 536, 8 studies) had evidence of glenoid erosion, 10.4% had changes in implant positioning, and 9.9% had tuberosity thinning. In addition, 1.5% of patients had radiographic subacromial space reduction, whereas 0.7% had an increase in tuberosity thickness. Across all studies, there was an 8.6% complication rate, with the most common cause being glenoid erosion (2.6%, n = 14). There was an overall 7.7% revision rate (n = 41), with 63% of revisions (n = 26) undergoing conversion to reverse or total shoulder arthroplasty. CONCLUSION: PyC hemiarthroplasty shows overall improvements in ROM and patient-reported outcomes for patients. However, there remains concern for glenoid erosion on radiographic evaluation at minimum 2-year follow-up. Although preliminary studies have shown encouraging results, this systematic review emphasizes the need for longer-term follow-up studies with further radiographic evaluation of the severity of glenoid erosion and the association with functional outcomes and failure risk.

ECMO simulation: How much, who to train, and a review of cost, fidelity and performance.

BACKGROUND: Extracorporeal Membrane Oxygenation (ECMO) is a high-risk, low-volume procedure requiring repetition, skill and multiple disciplines with fidelity of communication. Yet many barriers exist to maintain proficiency and skills with variable cost and fidelity. We designed and implemented a low-cost monthly ECMO simulation and hypothesized providers would have increased familiarity and improved teamwork. We also review some key elements of cost, fidelity and evaluation of effectiveness. METHODS: A structured, 1-hour ECMO simulation was performed on a customized mannikin on a monthly basis in 2022. Qualitative surveys were administered to each member post-simulation. Answers were categorized by theme, including satisfaction of patient care, evaluation of self and team dynamics, and areas for improvement. RESULTS: Most participants were satisfied with their ability to take care of the patient, with common themes of communication and coordination of roles. Identified areas of improvement were mostly limited to technical skills, and soft skills such as communication and teamwork. CONCLUSIONS: We designed and implemented a low-cost, monthly and multi-disciplinary ECMO simulation program with overall positive feedback and identified areas for improvement. There remains variability in cost, fidelity and evaluation of performance and retention. There may be a need to create guidelines for ECMO simulation training that can be applied at all institutions utilizing ECMO for patient care.

The Distinction Between Social Connectedness and Support When Examining Depressive Symptoms Among Children and Adolescents During the COVID-19 Pandemic.

Childhood depression is associated with significant social and functional impairment, suicide risk, and persistence throughout adulthood. Recent evidence demonstrates that social connectedness and social support may serve as protective factors against the development of depression. The current study aimed to examine the effect of change in social connectedness and social support on depressive symptoms among children and adolescents during the COVID-19 pandemic. Hierarchical regression was performed. Results indicated that parent-reported measures of change in social connectedness were inversely associated with depressive symptom severity, and could significantly predict future depressive symptom severity. In contrast, parent-reported measures of social support (i.e., from family and friends) did not significantly predict future depressive symptom severity. The presence of a pre-COVID psychiatric and/or neurodevelopmental diagnosis and baseline depressive symptom severity were also important factors associated with future depressive symptom severity. The findings suggest that an awareness of the presence of social supports (i.e., family or friends) is not sufficient for children to feel connected, but rather the mechanisms of social relationships are crucial. As our approach to public health restrictions evolves, the risk transmission of COVID-19 should be carefully balanced with the risks associated with decreased connectedness among youth.

The characteristics of opioid use in patients with proximal humerus fractures.

BACKGROUND: Orthopaedic surgeons prescribe more opioid narcotics than any other surgical specialty. Proximal humerus fractures (PHF) often occur in the high-risk elderly population. The opioid epidemic has led to public policy aimed at reductions in opioid prescription. This study aimed to evaluate the impact that new legislation has had on opioid prescription patterns in patients who sustained proximal humerus fractures. METHODS: A retrospective review of all patients who sustained PHF at a single academic institution from 1/1/2015-12/31/2019 was performed. A total of 762 proximal humerus fractures were identified and final analysis included 383 patients. Collected data included basic demographics and opioid prescriptions obtained through review of the electronic medical record. The North Carolina Strengthen Opioid Misuse Prevention act legislation that went into effect on July 1, 2017. RESULTS: There was no difference in the number of pre- or postoperative opioid prescriptions provided with the new legislation. Our data showed a significant reduction in MeQs prescribed preoperatively pre-STOP act (188.1 MeQs) and post-STOP act (99.4 MeQs). There was also a significant difference in the amount of postoperative narcotics prescribed in the pre-STOP (972.6 MeQs) and post-STOP act (508.6 MeQs) groups (p < 0.01). CONCLUSIONS: With the enactment of the STOP act in North Carolina, we have seen a significant reduction in the amount of narcotic prescribed after sustaining a proximal humerus fracture preoperatively and postoperatively. This data demonstrates the impact that implementation of state-wide regulatory changes in opioid prescribing policy has had for a common orthopedic condition.

Under the Lens: Team Perception of Trauma Video Review.

BACKGROUND: Video-based assessment and review are becoming increasingly common, and trauma video review (TVR) has been shown to be an effective educational, quality improvement, and research tool. Yet, trauma team perception of TVR remains incompletely understood. OBJECTIVE: We evaluated positive and negative perceptions of TVR across multiple team member groups. We hypothesized that members of the trauma team would find TVR educational and that anxiety would be low across all groups. METHODS: An anonymous electronic survey was provided to nurses, trainees, and faculty during weekly multidisciplinary trauma performance improvement conference following each TVR activity. Surveys assessed perception of performance improvement and anxiety or apprehension (Likert scale: 1 "strongly disagree" to 5 "strongly agree"). We report individual and normalized cumulative scores (average of responses for each positive [n = 6] and negative [n = 4] question stem). RESULTS: We analyzed 146 surveys over 8 months, with 100% completion rate. Respondents were trainees (58%), faculty (29%), and nurses (13%). Of the trainees, 73% were postgraduate year (PGY) 1-3 and 27% were PGY 4-9. Of all respondents, 84% had participated previously in a TVR conference. Respondents reported an improved perception of resuscitation education quality and personal leadership skills development. Participants found TVR to be more educational than punitive overall. Analysis of team member types showed lower scores for faculty for all positive stemmed questions. Trainees were more likely to agree with negative stemmed questions if they were a lower PGY, and nurses were least likely to agree with negative stemmed questions. CONCLUSIONS: TVR improves trauma resuscitation education in a conference setting, with trainees and nurses reporting the greatest benefit. Nurses were noted to be the least apprehensive about TVR.

Provider Perception of Time During Trauma Resuscitation: A Prospective Quantitative Trauma Video Review Analysis.

INTRODUCTION: Delays in transition to the next phase of care result in increased mortality. Prehospital literature suggests emergency medical service technicians underestimate transport times by as much as 20%. What remains unknown is clinician perception of time during the trauma resuscitation. We sought to determine if clinicians have an altered perception of time. We hypothesized that clinicians underestimate time, resulting in delay of care. METHODS: Clinicians at a large level 1 trauma center completed a post-trauma activation survey on the perceived elapsed time to complete three specific resuscitation endpoints. The primary study endpoint was the time to the next phase of care, defined as leaving the trauma bay to go to the operating room, interventional radiology, computerized tomography or time of death. The data from the surveys were linked and compared with recorded videos of the resuscitations. The difference in perceived versus actual time, along with confounding variables, was used to assess the impact of perception of time on the time to the next phase of care using a stepwise multivariate linear model. RESULTS: There were 284 complete surveys and videos, culminating in 543 time points. The median perceived versus actual time (minutes [interquartile range]) to the next phase of care was 20 [10-25] versus 26 [19-40] (P < 0.001). Overall, clinicians underestimated time by 28%, such that if the resuscitation lasted 20 min, the clinician's perception was that 14.4 min elapsed. Differences in the perceived versus actual time in the procedure group impacted time to the next phase of care (P = 0.01). CONCLUSIONS: Clinicians have significant gaps in the perception of time during trauma resuscitations. This misperception occurs during procedures and correlates with an increase in the length of time to the next phase of care.

Monthly Trauma Training and Simulation Are Associated With Improved Resident Skill and Leadership.

BACKGROUND: Training for trauma procedures has been limited to infrequent courses with little data on longitudinal performance, and few address procedural and leadership skills with granular assessment. We implemented a novel training program that emphasized an assessment of trauma resuscitation and procedural skills. OBJECTIVE: This study aimed to determine whether this program could demonstrate improvement in both skill sets in surgical trainees over time. METHODS: This was a prospective, observational study at a Level I trauma center between November 2018 and May 2019. A procedural skill and simulation program was implemented to train and evaluate postgraduate year (PGY) 1-5 residents. All residents participated in an initial course on procedures such as tube thoracostomy and vascular access, followed by a final evaluation. Skills were assessed by the Likert scale (1-5, 5 noting mastery). PGY 3s and above were additionally evaluated on resuscitation. A paired t test was performed on repeat learners. RESULTS: A total of 40 residents participated in the structured procedural skills and simulation program. Following completion of the program, PGY-2 scores increased from a Mdn [interquartile range, IQR] 3.0 [2.5-4.0] to 4.5 [4.2-4.5]. The PGY-3 scores increased from a Mdn [IQR] 3.95 [3.7-4.6] to 4.8 [4.6-5.0]. Eighteen residents underwent repeat simulation training, with Mdn [IQR] score increases in PGY 2s (3.7 [2.5-4.0] to end score 4.47 [4.0-4.5], p = .03) and PGY 3s (3.95 [3.7-4.6] to end score 4.81 [4.68-5.0], p = .04). Specific procedural and leadership skills also increased over time.

Safety of Erector Spinae Plane Blocks in Patients With Chest Wall Trauma on Venous Thromboembolism Prophylaxis.

BACKGROUND: Current guidelines for severe rib fractures recommend neuraxial blockade in addition to multimodal pain therapies. While the guidelines for venous thromboembolism prevention recommend chemoprophylaxis, these medications must be held for neuraxial blockade placement. Erector spinae plane block (ESPB) is a newly described block for thoracic pain control. Advantages include its quick learning curve and potential for less bleeding complications. We describe the use of ESPB for rib fractures in patients on chemoprophylaxis. We hypothesize that ESPB can be performed in this patient population without holding chemoprophylaxis. MATERIALS AND METHODS: This was a retrospective observational cohort study of a level 1 trauma center from 9/2016 to 12/2018. All patients with trauma with rib fractures undergoing neuraxial blockade or ESPB were included. Demographics, chemoprophylaxis and anticoagulation regimens, outcomes, and complications were collected. RESULTS: Nine hundred sixty-four patients with rib fracture(s) were admitted. Of these, 73 had a pain management consult. Thirteen had epidural catheters and 25 had ESPBs placed. There was no difference in demographics, injury patterns, bleeding complications, or venous thromboembolism rates among the groups. Patients with ESPB were less likely to have a dose of chemoprophylaxis held because of placement of a catheter (25% versus 100%, P < 0.00001). Three patients with ESPB were on oral anticoagulation on admission, and two were able to continue their regimen during placement. CONCLUSIONS: ESPB can be safely placed in patients on chemoprophylaxis. It should be considered over traditional blocks in patients with blunt chest wall trauma because of its technical ease and ability to be performed with chemoprophylaxis.

Characterizing the gut microbiota in adults with bipolar disorder: a pilot study.

Background: Convergent evidence implicates gut microbiota in human health and disease. Hitherto, relatively few studies have evaluated the gut microbiota profile in individuals with bipolar disorder (BD) relative to healthy controls (HC). Methods: Fecal samples were collected from subjects (aged 18-65) meeting DSM-5-defined criteria for BD and age- and sex-matched HC without current or past history of mental or major medical disorders. Samples were sequenced using Illumina sequencing and association of specific taxa and co-occurrence of taxa with sample groups including the effect of diet was assessed using cluster analysis and analysis of communities of microorganisms (ANCOM). Nutritional composition was evaluated using the Dietary Questionnaire for Epidemiological Studies (DQES v2) Food Frequency Questionnaire. Results: Forty-six subjects were enrolled (n=23 BD, n=23 HC). Cluster analyses did not identify any significant differences between BD and HC (p=0.38). Lower microbiota diversity was observed among BD subjects relative to HC (p=0.04). A greater abundance of a Clostridiaceae OTU was observed among BD subjects when compared to HC and of Collinsella among BD-II subjects relative to BD-I. Cluster analysis revealed that neither diagnosis (p=0.38) nor diet (p=0.43) had a significant effect on overall gut microbiota composition. Limitations: This study has a small sample size and insufficient control for some potential moderating factors (e.g. psychotropic medication and smoking). Conclusion: This study suggests that individuals with BD may have a distinct gut microbiota profile compared to healthy controls, with a greater abundance of Clostridiaceae and Collinsella. These findings need to be replicated in future studies with larger sample sizes.

Comparison of Appendectomy for Perforated Appendicitis With and Without Abscess: A National Surgical Quality Improvement Program Analysis.

BACKGROUND: Outcomes of appendectomy stratified by type of complicated appendicitis (CA) features are poorly researched, and the evidence to guide operative versus nonoperative management for CA is lacking. This study aimed to determine laparoscopic-to-open conversion risk, postoperative abscess risk, unplanned readmission risk, and length of hospital stay (LOS) associated with appendectomy in patients with perforated appendicitis without abscess (PA) and perforated appendicitis with abscess (PAWA) compared with a control cohort of nonperforated appendicitis (NPA). METHODS: The 2016-2017 National Surgical Quality Improvement Program Appendectomy-targeted database identified 12,537 (76.1%) patients with NPA, 2142 (13.0%) patients with PA, and 1799 (10.9%) patients with PAWA. Chi-squared analysis and analysis of variance were used to compare categorical and continuous variables. Binary logistic and linear regression models were used to compare risk-adjusted outcomes. RESULTS: Compared with NPA, PA and PAWA had higher rates of conversion (0.8% versus 4.9% and 6.5%, respectively; P < 0.001), postoperative abscess requiring intervention (0.6% versus 4.8% and 7.0%, respectively; P < 0.001), readmission (2.8% versus 7.7% and 7.6%, respectively; P < 0.001), and longer median LOS (1 day versus 2 days and 2 days, respectively; P < 0.001). PA and PAWA were associated with increased odds of postoperative abscess (odds ratio [OR]: 7.18, 95% confidence interval [CI]: 5.2-9.8 and OR: 9.94, 95% CI: 7.3-13.5, respectively), readmission (OR: 2.70, 95% CI: 2.1-3.3 and OR: 2.66, 95% CI: 2.2-3.3, respectively), and conversion (OR: 5.51, 95% CI: 4.0-7.5 and OR: 7.43, 95% CI: 5.5-10.1, respectively). PA was associated with an increased LOS of 1.7 days and PAWA with 1.9 days of LOS (95% CI: 1.5-1.8 and 1.7-2.1, respectively). CONCLUSIONS: Individual features of CA were independently associated with outcomes. Further research is needed to determine if surgical management is superior to nonoperative management for CA.

Smartphone applications for the treatment of depressive symptoms: A meta-analysis and qualitative review.

BACKGROUND: Emerging research indicates that the use of smartphone mental health applications (apps) could be used as an adjunctive therapy for individuals with depression, especially those who have difficulty accessing conventional therapies. The adoption and ownership of smartphone technology continues to increase in developed and developing nations, and could provide widespread and cost-effective evidence-based treatments for depressive symptoms. METHODS: The primary objective of this meta-analysis was to quantitatively evaluate the effects of smartphone mental health app interventions on depressive symptoms. Identified studies were qualitatively reviewed to address the following secondary objectives: (1) identify the types of smartphone apps currently being used to target depression; (2) identify factors associated with positive response to smartphone apps in depression; (3) provide directives for future research and app development; and (4) characterize the therapeutic opportunity of smartphone app interventions among individuals with depression. RESULTS: The results indicate that there may be some therapeutic opportunity with smartphone interventions as an adjunctive treatment for depression. In particular, we observed a small effect in favor of smartphone app interventions for reducing depressive symptoms. However, because of the significant heterogeneity across studies, continued research among more homogenous samples is warranted to determine whether these interventions might have larger (ie, more clinically relevant) effects in specific subpopulations and/or whether specific app characteristics produce larger effects. CONCLUSIONS: The current study highlights some key areas of priority going forward, particularly concerning the design of future studies and the development of novel technologies with a user-centered focus.

Cardiopulmonary Resuscitation in Intensive Care Unit Patients With Coronavirus Disease 2019.

Cardiopulmonary resuscitation (CPR) in patients with severe acute respiratory syndrome coronavirus-2-associated disease (coronavirus disease 2019) poses a unique challenge to health- care providers due to the risk of viral aerosolization and disease transmission. This has caused some centers to modify existing CPR procedures, limit the duration of CPR, or consider avoiding CPR altogether. In this review, the authors propose a procedure for CPR in the intensive care unit that minimizes the number of personnel in the immediate vicinity of the patient and conserves the use of scarce personal protective equipment. Highlighting the low likelihood of successful resuscitation in high-risk patients may prompt patients to decline CPR. The authors recommend the preemptive placement of central venous lines in high-risk patients with intravenous tubing extensions that allow for medication delivery from outside the patients' rooms. During CPR, this practice can be used to deliver critical medications without delay. The use of a mechanical compression system for CPR further reduces the risk of infectious exposure to health- care providers. Extracorporeal membrane oxygenation should be reserved for patients with few comorbidities and a single failing organ system. Reliable teleconferencing tools are essential to facilitate communication between providers inside and outside the patients' rooms. General principles regarding the ethics and peri-resuscitative management of coronavirus 2019 patients also are discussed.

Efficacy and safety of glecaprevir/pibrentasvir in patients with chronic HCV infection and psychiatric disorders: An integrated analysis.

Although direct-acting antivirals (DAAs) for chronic hepatitis C virus (HCV) infection are highly efficacious and safe, treatment initiation is often limited in patients with neuropsychiatric disorders due to concerns over reduced treatment adherence and drug-drug interactions. Here, we report adherence, efficacy, safety and patient-reported outcomes (PROs) from an integrated analysis of registrational studies using the pangenotypic DAA regimen of glecaprevir and pibrentasvir (G/P). Patients with chronic HCV genotypes 1-6 infection with compensated liver disease (with or without cirrhosis) receiving G/P for 8, 12 or 16 weeks were included in this analysis. Patients were classified as having a psychiatric disorder based on medical history and/or co-medications. Primary analyses assessed treatment adherence, efficacy (sustained virologic response at post-treatment week 12; SVR12), safety and PROs. Among 2522 patients receiving G/P, 789 (31%) had a psychiatric disorder with the most common diagnoses being depression (64%; 506/789) and anxiety disorders (27%; 216/789). Treatment adherence was comparably high (>95%) in patients with and without psychiatric disorders. SVR12 rates were 97.3% (768/789; 95% CI = 96.2-98.5) and 97.5% (1689/1733; 95% CI = 96.7-98.2) in patients with and without psychiatric disorders, respectively. Among patients with psychiatric disorders, SVR12 rates remained >96% by individual psychiatric diagnoses and co-medication classes. Overall, most adverse events (AEs) were mild-to-moderate in severity with serious AEs and AEs leading to G/P discontinuation occurring at similarly low rates in both patient populations. In conclusion, G/P treatment was highly efficacious, well-tolerated and demonstrated high adherence rates in patients with chronic HCV infection and psychiatric disorders.
