Systematic review search strategies are poorly reported and not reproducible: a cross-sectional metaresearch study.

OBJECTIVES: To determine the reproducibility of biomedical systematic review search strategies. STUDY DESIGN AND SETTING: A cross-sectional reproducibility study was conducted on a random sample of 100 systematic reviews indexed in MEDLINE in November 2021. The primary outcome measure is the percentage of systematic reviews for which all database searches can be reproduced, operationalized as fulfilling six key Preferred Reporting Items for Systematic reviews and Meta-Analyses literature search extension (PRISMA-S) reporting guideline items and having all database searches reproduced within 10% of the number of original results. Key reporting guideline items included database name, multi-database searching, full search strategies, limits and restrictions, date(s) of searches, and total records. RESULTS: The 100 systematic review articles contained 453 database searches. Only 22 (4.9%) database searches reported all six PRISMA-S items. Forty-seven (10.4%) database searches could be reproduced within 10% of the number of results from the original search; six searches differed by more than 1,000% between the originally reported number of results and the reproduction. Only one systematic review article provided the necessary search details to be fully reproducible. CONCLUSION: Systematic review search reporting is poor. To correct this will require a multifaceted response from authors, peer reviewers, journal editors, and database providers.

Smartphone use in Neurology: a bibliometric analysis and visualization of things to come.

Background and objectives: Smartphones are a ubiquitous part of society with increasing use as a healthcare tool. We aimed to analyze the published literature on smartphone usage within the field of Neurology to define the scientific landscape and forecast future research initiatives. Methods: We performed a bibliometric review of smartphone uses in Neurology based on a search of two Web of Science databases from inception through September 16, 2022. This librarian-guided review was conducted using Bibliometrix for data assessment and visualization. Temporal trends in publications, citation counts, collaborations, and author affiliations were among key metrics evaluated. VOS viewer identified hot spots based on generating co-occurrences and bibliographic coupling mapping. Results: Our search found 3,920 publications. The U.S. produced the most topic-based publications, collaborating most frequently with U.K., Canada, and China-based authors. The most prolific institutions included Karolinska Institute, University of Sydney, and University of Pittsburgh. Bioelectromagnetics, Stroke, and Neurology were the most cited journals. Rapid growth in scientific production occurred in recent years, including during the COVID-19 pandemic. Hotspots and keyword co-occurrence included telehealth, machine learning, and self-management. Temporal trends reflect transitioning from a focus of initial publications regarding mobile phone safety to more recent application of smartphones as "smart" tools for single modality diagnosis, monitoring, management, and treatment of neurological diseases. Discussion: There has been rapid expansion of the published literature on smartphone uses in Neurology. Initial focus on smartphones and health risk has shifted to uses for neurological disease diagnosis, detection, and management, with relevance as a global interface for collaboration and clinical practice.

A Scoping Review of Simulation-Based Training Paradigms for Carotid Artery Endarterectomy and Carotid Artery Stenting.

BACKGROUND: Surgical simulation has come to the forefront to enhance the training of residents. The aim of our scoping review is to analyze the available simulation-based carotid revascularization techniques, including carotid endarterectomy (CEA) and carotid artery stenting (CAS) and suggest critical steps for evaluating competency in a standardized fashion. METHODS: A scoping review of all reports on simulation-based carotid revascularization techniques including CEA and CAS was performed in PubMed/MEDLINE, Scopus, Embase, Cochrane, Science Citation Index Expanded, Emerging Sources Citation Index, and Epistemonikos databases. Data were collected according to the Preferred Reporting Items for Systematic Reviews and Meta-analysis guidelines. The English language literature was searched from January 1, 2000 to January 9, 2022. The outcomes evaluated included measures of assessment of operator performance. RESULTS: Five CEA and 11 CAS manuscripts were included in this review. The methods of assessments employed by these studies to judge performance were comparable. The 5 CEA studies sought to validate and demonstrate improved performance with training or distinguish surgeons by their experience level, either through assessing operative performance or end-product results. The 11 CAS studies used 1 of 2 types of commercial simulators and focused on determining the efficacy of simulators as teaching tools. By examining the steps of the procedure associated with preventable perioperative complications, it provides a reasonable framework for determining which elements of the procedure should be emphasized most. Furthermore, using potential errors as a basis for assessment of competency could reliably distinguish operators based on level of experience. CONCLUSIONS: Competency-based simulation training is becoming more relevant as our surgical training paradigm shifts with the increased scrutiny within training programs of work-hour regulations and the need to develop a curriculum to assess our trainees' ability to perform specific operations competently during their stipulated training period. Our review has given us an insight into the current efforts in this space regarding 2 specific procedures that are key for all vascular surgeons to master. Although many competency-based modules are available, there is a lack of standardization in the grading/rating system of what surgeons consider vital steps of each procedure to assess these simulation-based modules. Therefore, the next steps of curriculum development should be based on standardization efforts for the different protocols available.

Listening to Learners to Prepare for the Future: A Mayo Clinic College of Medicine and Science Benchmarking Survey.

In 2022, a benchmarking survey was completed to gage learner satisfaction with library services, spaces, and resources across 10 Mayo Clinic Libraries. The discussion for this project began around a previously published survey of what medical students wanted from their library. Librarians were asked if Mayo Clinic Libraries could do a similar survey, as a full survey of the Mayo Clinic College of Medicine and Science had not been done. Overall, the findings were positive and provide a baseline for future surveys.

ACG Clinical Guideline: Diagnosis and Management of Biliary Strictures.

A biliary stricture is an abnormal narrowing in the ductal drainage system of the liver that can result in clinically and physiologically relevant obstruction to the flow of bile. The most common and ominous etiology is malignancy, underscoring the importance of a high index of suspicion in the evaluation of this condition. The goals of care in patients with a biliary stricture are confirming or excluding malignancy (diagnosis) and reestablishing flow of bile to the duodenum (drainage); the approach to diagnosis and drainage varies according to anatomic location (extrahepatic vs perihilar). For extrahepatic strictures, endoscopic ultrasound-guided tissue acquisition is highly accurate and has become the diagnostic mainstay. In contrast, the diagnosis of perihilar strictures remains a challenge. Similarly, the drainage of extrahepatic strictures tends to be more straightforward and safer and less controversial than that of perihilar strictures. Recent evidence has provided some clarity in multiple important areas pertaining to biliary strictures, whereas several remaining controversies require additional research. The goal of this guideline is to provide practicing clinicians with the most evidence-based guidance on the approach to patients with extrahepatic and perihilar strictures, focusing on diagnosis and drainage.

From Alpha to Zeta: A Systematic Review of Zeta Waves.

PURPOSE: Electroencephalogram is used for prognostication and diagnosis in critically ill patients and is vital in developing clinical management algorithms. Unique waveforms on EEG may distinguish neurological disorders and define a potential for seizures. To better characterize zeta waves, we sought to define their electroclinical spectrum. METHODS: We performed a systematic review using MEDLINE, Embase, Cochrane Central Register of Controlled Trials and Cochrane Database of Systematic Review [through Ovid], Scopus, Science Citation Index Expanded and Emerging Sources Citation Index [through the Web of Science], and Epistemonikos. Grey literature resources were searched. RESULTS: Five hundred thirty-seven articles were identified. After excluding duplicates and reviewing titles, abstracts, and bodies and bibliographies of articles, four studies reported 64 cases describing data from patients with zeta waves, with a prevalence of 3 to 4%. Various and often incomplete clinical, neuroimaging, and EEG data were available. 57 patients (89.1%) had a focal cerebral lesion concordant with the location of zeta waves on EEG. 26 patients (40.6%) had clinical seizures, all but one being focal onset. Thirteen patients (20%) had epileptiform activity on EEG. Typically, zeta waves were located in the frontal head regions, often with generalized, frontal, predominant, rhythmic delta activity and associated with focal EEG suppression. CONCLUSIONS: Zeta waves frequently represent an underlying focal structural lesion. Their presence suggests a heightened risk for seizures. The small number of retrospective cases series in the literature reporting zeta waves might be an underrepresentation. We suggest a need for prospective studies of cEEG in critically ill patients to determine their clinical significance.

Systematic review of endovascular versus laparoscopic extravascular stenting for treatment of nutcracker syndrome.

OBJECTIVE: The aim of the present study was to assess the current strategies of endovascular and laparoscopic extravascular stenting for symptomatic compression of the left renal vein (LRV), most frequently between the aorta and superior mesenteric artery (nutcracker syndrome [NCS]). METHODS: We performed a systematic review of all studies of endovascular and laparoscopic extravascular LRV stenting for NCS using the PubMed/MEDLINE, Scopus, Embase, Cochrane, Science Citation Index Expanded, Emerging Sources Citation Index, and Epistemonikos databases. Data were collected in accordance with the PRISMA (preferred reporting items for systematic reviews and meta-analysis) guidelines. The English, Spanish, and German language literature was searched from January 1, 1946 to February 9, 2022. The outcomes assessed included symptom resolution, hematuria resolution, and reintervention at follow-up. RESULTS: The search yielded 3498 reports. After removing the duplicates and those without the full text available, 1724 studies were screened. Of these, 11 studies were included in the present review. Of the 11 studies, 7 were on endovascular stenting and 4 on laparoscopic extravascular stenting; all 11 studies were retrospective, single-center case series. Of the 233 patients, 170 (80 women) had undergone endovascular stenting and 63 (9 women) had undergone extravascular stenting. The follow-up period varied from 1 to 60 months after endovascular stenting and 3 to 55 months after extravascular stenting. The symptoms had resolved in 76% (range, 50%-100%) after endovascular stenting and 83% (range, 71%-100%) after extravascular stenting. Hematuria had resolved in 86% (range, 60%-100%) after endovascular stenting and 89% (range, 77%-100%) after extravascular stenting. Of 185 patients, 9 had required reintervention after endovascular stenting and none after extravascular stenting. CONCLUSIONS: Endovascular and laparoscopic extravascular stenting are less invasive and, thus, more attractive treatment options that have been more recently developed for the management of NCS. The results from the present study have shown that symptom and hematuria resolution must be provided before they can be considered preferred management options for patients affected by NCS. Given the limited number of patients involved, no definitive conclusion could be drawn regarding the superiority of one technique compared with the other.

A Systematic Review and Meta-Analysis Comparing Burn Healing Outcomes Between Silver Sulfadiazine and Aloe vera.

Burn wounds remain a prevalent problem in the developed and developing world. A multitude of remedies has been tested. This study evaluated the healing time of second- and third-degree burn wounds between silver sulfadiazine (SSD) and Aloe vera (AV). In July 2020, a systematic review of MEDLINE (Ovid) and PubMed (National Library of Medicine) was performed to identify studies that reported healing of second- and third-degree burns using either SSD or AV. Articles meeting the inclusion criteria were screened and carefully analyzed. Our goal was to report the healing time for these burns using SSD and AV. A total of eight studies published between 1988 and 2018 reporting healing of second- and third-degree burns using SSD and AV were included in this review. Six were cohort studies and two were randomized controlled trials. The studies included both animal and human subjects. The meta-analysis demonstrated that the mean time to wound healing favored AV (RR: -1.34, 95% CI: -1.8 to 0.9, p < 0.001). It would seem that time to healing benefitted those burns in which AV was utilized. In conclusion, increased consideration and emphasis should be placed on using AV to aid the healing of second- and third-degree burns.

Skin Cancer in Solid Organ Transplant Recipients: A Review for the Nondermatologist.

Solid organ transplant recipients (SOTRs) are at increased risk for the development of skin cancer compared with the general population, which requires consistent monitoring and management from a multidisciplinary team. The aim of this review is to provide a comprehensive overview for nondermatologist clinicians, outlining skin cancer diagnosis, treatment pearls, and skin cancer prevention strategies as they relate to SOTRs. A comprehensive search of the literature was conducted through the MEDLINE database with search terms including organ transplantation, transplant recipient, skin cancer, cutaneous neoplasms, management, and therapies. The search was limited to the English language and dates ranging from January 1, 2011, to December 28, 2021. All studies were reviewed for inclusion. Skin cancer will develop in more than half of SOTRs at some point in their life, most often nonmelanoma skin cancer such as basal cell carcinoma or squamous cell carcinoma. Melanoma and rarer cutaneous malignant neoplasms, such as Merkel cell carcinoma and Kaposi sarcoma, are also more frequent among SOTRs. A multidisciplinary effort at skin cancer screening and patient education is invaluable to prevent skin cancer-related morbidity and mortality in this population of patients. Reduction in immunosuppressive medications and surgical intervention are effective therapeutic approaches, and more novel systemic therapies including G protein-coupled receptor inhibitors and immune checkpoint inhibitors are possible options when traditional treatment approaches are not feasible. Checkpoint inhibitor therapy, however, comes with the risk of allograft rejection. With a growing and aging SOTR population, it is essential that SOTRs have support from dermatologists and nondermatologists alike in skin cancer prevention and treatment.

A systematic review and meta-analysis of racial disparities in deep vein thrombosis and pulmonary embolism events in patients hospitalized with coronavirus disease 2019.

OBJECTIVE: Coronavirus disease 2019 (COVID-19) is associated with an increased risk of venous thromboembolism (VTE). Recent studies have characterized racial disparities in the incidence of VTE. The aim of our study was to present a systematic review and meta-analysis to assess the association between race and VTE in patients hospitalized with COVID-19. METHODS: We performed a systematic literature review to evaluate the number of deep vein thrombosis (DVT) and pulmonary embolism (PE) events reported by racial groups in patients hospitalized with COVID-19. For the qualitative analysis, independent reviewers extracted the data from eligible studies, and we used the Newcastle-Ottawa scale to assess the quality of design and content for accurate interpretation. For the quantitative analysis, we pooled the odds ratios with Der Simonian and Laird random effects models. RESULTS: The qualitative analysis included 11 studies, with 6 included in the meta-analysis. All studies were observational, retrospective cohort studies, except for one retrospective case-control study. Six studies were eligible for the meta-analysis owing to the high interstudy heterogeneity; thus, the variable reports of racial groups reduced the cohort to Black/African American and White patients (n = 9723) in the analysis. The estimated proportion for DVT and PE events for Black/African American and White patients was 0.07 (95% confidence interval, 0.00-0.10) and 0.04 (95% confidence interval, 0.00-0.07), respectively. The P value of .13 suggested nonsignificant differences in the VTE rates between Black/African American and White patients. CONCLUSIONS: In our study, the proportion of DVT and PE events between Black/African American and White patients with COVID-19 were comparable. Future COVID-19 studies should include systematic racial group reporting to identify any disparities in the setting of VTE events.

A Systematic Review of Nutritional Lab Correlates with Chemotherapy Induced Peripheral Neuropathy.

Chemotherapy induced peripheral neuropathy (CIPN) is a dose-limiting side effect of chemotherapy for which no prevention or cure exists. Cancer and cancer treatments can adversely affect nutritional status. Nutrition may play a role in development of CIPN, yet the relationship between nutrition and CIPN is not well understood. Common laboratory values measuring various aspects of nutrition (hemoglobin/hematocrit, vitamin B12, calcium, and magnesium) may be associated with CIPN. The aim of this systematic review is to evaluate the empirical evidence surrounding the relationship between laboratory measures of nutrition and CIPN among persons with cancer who received neurotoxic chemotherapy drugs. We conducted an extensive review of the literature to identify articles that evaluated relationships between laboratory measures of nutrition and CIPN. A total of eleven articles satisfied the inclusion/exclusion criteria. Participants in the studies had breast or colorectal cancer, lymphoma or multiple myeloma and were receiving a variety of neurotoxic drugs. Hemoglobin/hematocrit, vitamin D, albumin, and magnesium were associated with CIPN. The quality of the studies ranges from fair to good. Evidence suggests that low levels of the above-mentioned tests could be associated with CIPN but additional research is needed.

Preoperative echocardiography as a prognostic tool for liver transplant in patients with hypertrophic cardiomyopathy.

BACKGROUND: Hypertrophic cardiomyopathy (HCM) presents with a hypertrophied left ventricle (LV). It is often associated with LV outflow tract obstruction (LVOTO) and a risk for sudden death. This study aimed to describe outcomes of patients with HCM who underwent liver transplant (LT). METHODS: A retrospective review was conducted for patients diagnosed with HCM undergoing LT. Patient characteristics, preoperative echocardiography results, HCM risk of sudden cardiac death prediction model score, and 5-year mortality were examined. A univariable Cox proportional hazards model was used to evaluate the association between risk factors and 5-year mortality. All tests were two-sided with the alpha level set at .05. RESULTS: Twenty-nine patients were included in the analysis. Six patients (21%) had a perioperative cardiopulmonary complication. The 5-year survival rate was 61% (95% CI, 45-82). The analyzed risk factors showed that 5-year post-LT survival was significantly predicted by maximal LV outflow tract gradient at rest > 60 mmHg (hazard ratio, 1.04 [95% CI, 1.01-1.06]). CONCLUSIONS: Preoperative LV outflow tract resting gradient > 60 mmHg was associated with 5-year post-LT mortality. The results suggest the severity of LVOTO identified by echocardiography is a prognostic tool for patients with HCM after LT.

Cardiac structure and function in elite female athletes: A systematic review and meta-analysis.

We conducted a meta-analysis to synthesize the best available evidence comparing cardiac biventricular structure and function using cardiac magnetic resonance imaging (CMR) and transthoracic echocardiography (TTE) in elite female athletes and healthy controls (HC). Chronic exposure to exercise may induce cardiac chamber enlargement as a means to augment stroke volume, a condition known as the "athlete's heart." These changes have not been clearly characterized in female athletes. Multiple databases were searched from inception to June 18, 2019. Outcomes of interest included left ventricular (LV) and right ventricular (RV) dimensional, volumetric, mass, and functional assessments in female athletes. Most values were indexed to body surface area. The final search yielded 22 studies, including 1000 female athletes from endurance, strength, and mixed athletic disciplines. CMR-derived LV end-diastolic volume (LVEDV) and RV end-diastolic volume (RVEDV) were greater in endurance athletes (EA) versus HC (17.0% and 18.5%, respectively; both p < 0.001). Similarly, TTE-derived LVEDV and RVEDV were greater in EA versus HC (16.8% and 28.0%, respectively; both p < 0.001). Both LVEF and RVEF were lower in EA versus HC, with the most pronounced difference observed in RVEF via TTE (9%) (p < 0.001). LV stroke volume was greater in EA versus HC via both CMR (18.5%) and TTE (13.2%) (both p < 0.05). Few studies reported data for the mixed athlete (MA) population and even fewer studies reported data for strength athletes (SA), therefore a limited analysis was performed on MA and no analysis was performed on SA. This evidence-synthesis review demonstrates the RV may be more susceptible to ventricular enlargement. General changes in LV and RV structure and function in female EA mirrored changes observed in male counterparts. Further studies are needed to determine if potential adverse outcomes occur secondary to these changes.

V.I.T.A.M. in COVID 19: A Systematic Approach to a Global Pandemic.

INTRODUCTION: In the unprecedented era of COVID-19, ongoing research and evolution of evidence has led to ever-changing guidelines for clinical monitoring and therapeutic options. Formulating treatment protocols requires the understanding and application of the evolving research. OBJECTIVE: The primary objective of this study is to present a systematic evidence-based approach to synthesize the necessary data in order to optimize the management of COVID-19. METHODS: At Mayo Clinic Florida, we developed a multidisciplinary centralized COVID Treatment Review Panel (TRP) of expert pulmonologists, intensivists, infectious disease specialists, anesthesiologists, hematologists, rheumatologists, and hospitalists that in real-time reviews the latest evidence in peer-reviewed journals, the available clinical trials, and help guide the rapid application of therapeutics or interventions to the patient and the bedside provider. RESULTS/CONCLUSIONS: The multi-disciplinary team approach of synthesizing clinical data and coordinating care is effective in responding to rapidly evolving and changing evidence. Systematic data collection and evidence-based treatment algorithms enable physicians to rapidly translate the current literature to clinical practice, and improve care and outcomes of patients.

Evaluating Scholars' Impact and Influence: Cross-sectional Study of the Correlation Between a Novel Social Media-Based Score and an Author-Level Citation Metric.

BACKGROUND: The development of an author-level complementary metric could play a role in the process of academic promotion through objective evaluation of scholars' influence and impact. OBJECTIVE: The objective of this study was to evaluate the correlation between the Healthcare Social Graph (HSG) score, a novel social media influence and impact metric, and the h-index, a traditional author-level metric. METHODS: This was a cross-sectional study of health care stakeholders with a social media presence randomly sampled from the Symplur database in May 2020. We performed stratified random sampling to obtain a representative sample with all strata of HSG scores. We manually queried the h-index in two reference-based databases (Scopus and Google Scholar). Continuous features (HSG score and h-index) from the included profiles were summarized as the median and IQR. We calculated the Spearman correlation coefficients (ρ) to evaluate the correlation between the HSG scores and h-indexes obtained from Google Scholar and Scopus. RESULTS: A total of 286 (31.2%) of the 917 stakeholders had a Google Scholar h-index available. The median HSG score for these profiles was 61.1 (IQR 48.2), and the median h-index was 14.5 (IQR 26.0). For the 286 subjects with the HSG score and Google Scholar h-index available, the Spearman correlation coefficient ρ was 0.1979 (P<.001), indicating a weak positive correlation between these two metrics. A total of 715 (78%) of 917 stakeholders had a Scopus h-index available. The median HSG score for these profiles was 57.6 (IQR 46.4), and the median h-index was 7 (IQR 16). For the 715 subjects with the HSG score and Scopus h-index available, ρ was 0.2173 (P<.001), also indicating a weak positive correlation. CONCLUSIONS: We found a weak positive correlation between a novel author-level complementary metric and the h-index. More than a chiasm between traditional citation metrics and novel social media-based metrics, our findings point toward a bridge between the two domains.

Transbronchial Forceps Biopsy in the Intensive Care Unit: A Systematic Review and Meta-analysis.

BACKGROUND: A transbronchial forceps lung biopsy performed in mechanically ventilated patients with respiratory failure of unknown etiology has significant uncertainty of diagnostic yield and safety along with sparse literature. This study investigated the complication rate of transbronchial biopsies in mechanically ventilated patients in the intensive care unit and its ability to obtain a diagnosis and change current therapy. METHODS: PubMed, Ovid MEDLINE, and Ovid Cochrane Central Register of Controlled Trials databases were systematically searched for all publications of transbronchial lung biopsies in mechanically ventilated patients. We pooled the results of individual studies using random-effects meta-analysis models to achieve the summary proportions. RESULTS: Of the identified 9 observational studies with a total of 232 patients undergoing a transbronchial biopsy, complications occurred in 67 patients [25.2%; 95% confidence interval (CI), 11.5%-42.0%; I2=70.0%]. Pneumothorax occurred in 24 patients (9.5%; 95% CI, 4.5%-16.2%; I2=15.9%) and bleeding in 18 patients (8.9%; 95% CI, 4.1%-15.3%; I2=0%). A diagnosis was given in 146 patients (62.9%; 95% CI, 56.0%-69.1%; I2=74.6%), with 103 of 210 patients (49.0%; 95% CI, 44.6%-55.1%; I2=74.9%) having a change in treatment. CONCLUSION: The results of this meta-analysis suggest that a transbronchial forceps biopsy when performed in mechanically ventilated patients with respiratory failure of unclear etiology had a moderate complication rate. These biopsies resulted in varied diagnoses with a high rate of management change. Randomized controlled trials are necessary to identify the ideal patients to perform a transbronchial forceps biopsy on in the intensive care unit.

COVID-19 - Background and Health Sciences Library Response during the First Months of the Pandemic.

COVID-19, a novel respiratory disease caused by the SARS-CoV-2 coronavirus, was first recognized in Wuhan, China in December 2019 and declared a pandemic by the World Health Organization in March 2020. Health science librarians continue to navigate the global health crisis while providing critical information services to their institutions. An informal survey was conducted to obtain some general information on the types of responses by health science librarians to this event. Among the findings is an opportunity for librarians to strengthen interdepartmental relationships and disaster response plans in preparation for future pandemics and disaster events.

Higher Risk for Reintervention in Patients after Stenting for Radiation-Induced Internal Carotid Artery Stenosis: A Single-Center Analysis and Systematic Review.

BACKGROUND: This study aimed to review short- and long-term outcomes of all carotid artery stenting (CAS) in patients with radiation-induced (RI) internal carotid artery (ICA) stenosis compared with patients with atherosclerotic stenosis (AS). METHODS: We performed a single-center, multisite case-control study of transfemoral carotid artery intervention in patients stented for RI or AS. Cases of stented RI carotid arteries were identified using a CAS database covering January 2000 to December 2019. These patients were randomly matched 2:1 with stented patients because of AS by age, sex, and year of CAS. A conditional logistic regression model was performed to estimate the odds of reintervention in the RI group. Finally, a systematic review was performed to assess the outcomes of RI stenosis treated with CAS. RESULTS: There were 120 CAS in 113 patients because of RI ICA stenosis. Eighty-nine patients (78.8%) were male, and 68 patients (60.2%) were symptomatic. The reasons for radiation included most commonly treatment for diverse malignancies of the head and neck in 109 patients (96.5%). The mean radiation dose was 58.9 ± 15.6 Gy, and the time from radiation to CAS was 175.3 ± 140.4 months. Symptoms included 31 transient ischemic attacks (TIAs), 21 strokes (7 acute and 14 subacute), and 17 amaurosis fugax. The mean National Institutes of Health Stroke Scale in acute strokes was 8.7 ± 11.2. In asymptomatic patients, the indication for CAS was high-grade stenosis determined by duplex ultrasound. All CAS were successfully completed. Reinterventions were more frequent in the RI ICA stenosis cohort compared with the AS cohort (10.1% vs. 1.4%). Reinterventions occurred in 14 vessels, and causes for reintervention were restenosis in 12 followed by TIA/stroke in two vessels. On conditional regression modeling, patients with RI ICA stenosis were at a higher risk for reintervention (odds ratio = 7.1, 95% confidence interval = 2.1-32.8; P = 0.004). The mean follow-up was 33.7 ± 36.9 months, and the mortality across groups was no different (P = 0.12). CONCLUSIONS: In our single-center, multisite cohort study, patients who underwent CAS for RI ICA stenosis experienced a higher rate of restenosis and a higher number of reinterventions compared with CAS for AS. Although CAS is safe and effective for this RI ICA stenosis cohort, further data are needed to reduce the risk of restenosis, and close patient surveillance is warranted. In our systematic review, CAS was considered an excellent alternative option for the treatment of patients with RI ICA stenosis. However, careful patient selection is warranted because of the increased risk of restenosis on long-term follow-up.

An Evidence-Based Approach to Casting and Orthosis Management of the Pediatric, Adolescent, and Young Adult Population for Injuries of the Upper Extremity: A Review Article.

OBJECTIVE: Review the use of upper-extremity orthoses and casts after injuries to the wrist and hand in the pediatric, adolescent, and young adult population. The common injuries reviewed include pediatric distal radius fractures, scaphoid fractures, metacarpal fractures, mallet fingers, volar plate injuries of the proximal interphalangeal (PIP) joint, and ulnar collateral ligament (UCL) tears of the thumb metacarpophalangeal (MCP) joint. DATA SOURCES: We conducted a literature review from 1985 to 2016 of upper-extremity orthotic interventions. Non-English language citations and animal studies were excluded. Citations from retrieved studies were used to identify other relevant publications. This review included cases of common injuries to the upper extremity, which required orthotic intervention. MAIN RESULTS: Immobilization recommendations for nonsurgical pediatric distal radius fractures, nonsurgical metacarpal fractures, mallet fingers, and UCL tears of the thumb MCP include a removable orthosis. Nondisplaced scaphoid fracture orthosis recommendations include initial immobilization in a nonremovable short-arm thumb spica cast. Volar plate injuries of the PIP joint require buddy straps for healing. CONCLUSIONS: The literature demonstrates the effectiveness of removable orthoses in healing, patient satisfaction, and time to return to activity after many common upper-extremity injuries. Removable orthoses should be considered an equal or superior treatment method to cast immobilization, immobilization of additional joints, or longer periods of immobilization.

Complications of Peripherally Inserted, Large-Bore, Rapid-Infusion Catheters in Orthotopic Liver Transplant Patients.

BACKGROUND: At our institution, peripherally inserted, 8.5-French rapid-infusion catheters (RICs) are placed for high-flow administration of intravenous fluids and blood products during liver transplant (LT). We sought to estimate the incidence of RIC placement-associated complications in LT patients. METHODS: Electronic health records of all patients who underwent LT from January 2008 through December 2017 were retrospectively reviewed. RIC-related complications were deemed clinically significant if they required surgical consultation or intervention due to infiltration. Univariable and multivariable logistic regression analyses were used to evaluate associations between patient characteristics and RIC complications. RESULTS: In total, 839 LT patients who received RICs were identified; of these, 14 (1.67%) had RIC-related complications, and 7 (0.83%) required surgical consultation. No patients needed fasciotomy or wound débridement due to a RIC complication, and no patients had permanent sequelae. In the multivariable logistic regression analysis, only an increase in international normalized ratio (INR) from 1.4 to 2.2 (equivalent to the interquartile range of observed INR values) increased the odds of complications due to RIC placement (odds ratio [95% CI], 1.98 [1.10-3.56]; P = .02). CONCLUSIONS: We observed a low incidence of perioperative RIC-related complications (1.7%). No patients had permanent RIC-related complications.
