Published: April 2021

Introduction Senior medical students learn trauma principles in a 90-min interactive teaching session based on the trauma evaluation and management module designed by the American College of Surgeons. However, the number of surgical faculty available to conduct these interactive small group sessions is limited. The goal of this study is to compare the effectiveness of surgical residents to that of surgical faculty in teaching trauma principles. Methods 53 senior medical students received trauma teaching from trauma faculty ( n = 22), trauma residents ( n = 21), or no teaching ( n = 10). Students were tested on cognitive trauma knowledge (20 multiple choice questions) and clinical trauma simulation (using objective structured clinical performance score). All students completed a 5-point subjective questionnaire. Results Students receiving trauma teaching outperformed students receiving no teaching in the knowledge test (mean 13.0 ± 3.6 standard deviation (SD) vs. 8.4 ± 2.4 SD, p < 0.05), while faculty and resident teaching outcomes were similar (mean 12.6 ± 3.0 SD vs. 13.4 ± 4.1, p = 0.45). Similarly, in the clinical trauma simulation, students receiving trauma teaching scored better (objective score mean 78% vs. 56%, p < 0.05), while there was no difference between faculty and resident teaching outcomes (objective score mean 77% vs. 80%, p = 0.52). In the subjective questionnaire, students who received trauma teaching rated themselves higher on a scale of 10 in trauma knowledge and skills than those who did not have formal teaching (mean 5.2 vs. 2.1, p < 0.05) as resident and attending teaching group ratings were similar. Conclusions Although small group discussions and increased simulation enhance undergraduate surgical trauma education, the number of faculty surgeons needed to fully incorporate these activities is limited. Objective and perceived effectiveness of teaching trauma management by surgical residents compared to trauma attendings is equivalent. This highlights the opportunity to incorporate residents into teaching roles to bridge the gap in undergraduate trauma education.

Background Person-centered care has been shown to increase desired outcomes for people with dementia, yet informal caregivers’ dissatisfaction with care is often reported. For those living in a nursing home, informal caregivers are uniquely situated to provide key insights into the individual’s care. However, little is known of the informal caregivers’ perspective, which hinders efforts to improve their satisfaction with person-centered nursing home care. Thus, we examined the comprehensive experiences, priorities, and perceptions of informal caregivers of nursing home residents with dementia. Methods In collaboration with stakeholders, a scoping review of Medline (Ovid), EMBASE.com , CINAHL (EBSCO), the Cochrane Library (Wiley), and PsycINFO (Ovid) databases from January 2000 to July 2020 was conducted. Data were extracted reflecting the experiences, priorities, and preferences of caregivers of people with dementia residing in nursing homes. Results We identified 114 articles that revealed nine themes: (1) communication, (2) transition to nursing home, (3) quality of care, (4) quality of life, (5) informal caregiver role, (6) knowledge of dementia, (7) end-of-life preferences, (8) medication use to manage neuropsychiatric behaviors, and (9) finances. Conclusion Informal caregivers described aspects of care that led to both positive and negative experiences with and perceptions of nursing home care. The shortcomings in communication were discussed most frequently, indicating a high priority area. While researchers define the identified themes individually, informal caregivers perceive them to be interwoven as they relate to person-centered care delivery. Although we did not assess the quality of included articles, by identifying themes relevant to caregivers’ perspectives of nursing home care, our findings may help to inform efforts to optimize caregivers’ satisfaction with nursing home care for residents with dementia.

Background. While advanced practice providers (APPs) are increasingly integrated into care delivery models, little is known about their impact in surgical settings. Given that many patients undergo surgery in multispecialty group practice settings, we examined the impact of APP integration into such practices on outcomes after major surgery. Methods. We used a 20% sample of national Medicare claims to identify 190 101 patients who underwent 1 of 4 major surgeries (coronary artery bypass graft [CABG], colectomy, major joint replacement, and cystectomy) at multispecialty group practices from 2010 through 2016. The level of APP integration was measured as the ratio of APPs to physicians within each practice. Rates of mortality, major complications, and readmission within 30 days of discharge after the index surgery were compared between patients treated in practices with low, medium, and high levels of APP integration using multivariable regression analysis. Results. Relative to patients treated in practices with low APP integration, those treated in practices with medium or high APP integration had significantly lower rates of mortality (2.4% [low integration] vs 1.9% [medium integration] vs 2.0% [high integration]; P < .01), major complications (34.1% [low] vs 31.2% [medium] vs 30.2% [high]; P < .01), and readmission (11.7% [low] vs 10.6% [medium] vs 10.1% [high]; P < .01). This relationship was consistent for virtually all outcomes when considering each surgery type individually. Conclusions. Integration of APPs into multispecialty group practices was associated with improved postoperative outcomes after major surgery. Future research should identify the mechanisms by which APPs improve outcomes to inform optimal utilization.

Background and purpose Flow diversion is commonly used to treat intracranial aneurysms in various regions of the cerebral vasculature, but is only approved for use in the internal carotid arteries. Treatment of distal PICA aneurysms with PED is sometimes performed but has not been well studied. Here, we report our experience with flow diversion of distal PICA aneurysms with PED. Materials and methods Clinical and angiographic data of eligible patients was retrospectively obtained and assessed for key demographic characteristics and clinical and angiographic outcomes. Principal outcomes included rates of aneurysm occlusion, ischemic or hemorrhagic complication, technical complication, and in-stent stenosis. Results Three female and 2 male patients underwent placement of PED in the PICA for treatment of 5 distal PICA aneurysms. Clinical and angiographic follow-up was obtained for all patients. Complete aneurysm occlusion was observed in 100% (5/5) of treated aneurysms at 6 month and longest angiographic follow-up. While there were no ischemic or device-related complications, delayed hemorrhagic complications occurred in 20% (1/5) of patients. Conclusion Pipeline embolization of distal PICA aneurysms can be performed in select patients. Further study is necessary in larger cohorts to better define clinical scenarios in which flow diversion in the distal PICA should be considered.

Background Carotid artery stenting is a minimally invasive, durable alternative treatment option, which is an alternative to the reference method, carotid endarterectomy, for patients with carotid artery stenosis; however, silent new ischemic cerebral lesions (SNICLs) after carotid artery stenting remain as a matter of concern. Hence, we aimed to assess the effect of complex vascular anatomy on silent new ischemic cerebral lesions in carotid artery stenting procedures. Methods We prospectively evaluated 122 patients (mean age: 69.5 ± 7.1 years, male:83) who underwent carotid artery stenting for carotid artery revascularization. The patients having symptomatic transient ischemic attack or stroke after carotid artery stenting were excluded. The presence of a new hyperintense lesions on diffusion-weighted imaging without any neurological findings was considered as the SNICL. Patients were classified into two groups as DWI-positive and DWI-negative patients. Results Among the study population, 32 patients (26.2%) had SNICLs. The DWI-positive group had a significantly higher common carotid artery (CCA)-internal carotid artery (ICA) angle, older age, more frequent history of stroke, a higher proportion of type III aortic arch, and longer fluoroscopy time than the DWI-negative group. High CCA-ICA angle was identified as one of the independent predictors of SNICL (OR (odds ratio) = 1.103 95%CI (confidence interval): (1.023–1.596); p = 0.034), and CCA-ICA angle higher than 34.5 degrees predicted SNICL with a sensitivity of 62.5% and a specificity of 62.2% (area under the curve: 0.680; 95% CI: 0.570 to 0.789; p = 0.003). Conclusions The higher CCA-ICA angle may predict pre-procedure SNICL risk in carotid artery stenting and may have clinical value in the management of patients with carotid artery stenosis.

Objective To compare the use of high saphenous ligation and stripping, radiofrequency ablation, and subfascial endoscopic perforator surgery for the treatment of active venous ulcers. Methods One hundred ninety-five ( n = 195) subjects who were treated for venous leg ulcers were enrolled between 2009 and 2014. Three groups were formed (Group A: high saphenous ligation and total stripping, Group B: radiofrequency ablation of the great saphenous vein + perforators, and Group C: radiofrequency ablation of the great saphenous vein + subfascial endoscopic perforator surgery) ( n = 65 for each group). The venous clinical severity score for baseline, 1st, 6th, and 12th months, great saphenous vein occlusion at the 1st, 6th, and 12th months, and ulcer rates for the 1st, 2nd, 3rd, 4th, and 5th years were recorded. Results For venous clinical severity score, only the first month decrease was significant for the subfascial endoscopic perforator surgery group ( p = 0.001). Great saphenous vein occlusion was higher at the 6th and 12th months for the high saphenous ligation and stripping and subfascial endoscopic perforator surgery groups than for the radiofrequency ablation group ( p = 0.036 and p = 0.037). The rate of ulcers for the subfascial endoscopic perforator surgery group was lower at the second, third, fourth, and fifth years ( p = 0.011). No significant difference was found between groups for the five-year recovery rates ( p > 0.05). Conclusion Subfascial endoscopic perforator surgery technique in conjunction with radiofrequency ablation of axial vein was superior to both high saphenous ligation and stripping and radiofrequency ablation of axial and perforators for ulcer healing.

Background/Aims: Many investigators have tested interventions to improve research participant understanding of information shared during the informed consent process, using a variety of methods and with mixed results. A valid criticism of most consent research is that studies are often conducted in simulated research settings rather than ongoing clinical studies. The present study rigorously tested two simple and easily adoptable strategies for presenting key consent information to participants eligible to enroll in six actual clinical trials (i.e. six parent studies). Methods: In collaboration with the study team from each parent study, we developed two consent interventions: a fact sheet and an interview-style video. The content of each of the intervention was based on the information shared in the consent form approved for each parent study. Participants were randomized to the standard consent process, or to one of the two interventions. Once exposed to the assigned consent mode, participants were asked to complete an assessment of understanding. The study was powered to determine whether those exposed to the fact sheet or video performed better on the consent assessment compared to those exposed to the standard consent. We also assessed participant satisfaction with the consent process. Results: A total of 284 participants were randomized to one of the three consent arms. Assessments of understanding were completed with a total of 273 participants from July 2017 to April 2019. Participants exposed to the video had better understanding scores compared to those exposed to the standard consent form process ( p value = 0.020). Participants were more satisfied with the video when compared to the standard consent. Participants who received the fact sheet did not achieve higher overall understanding or satisfaction scores when compared to the standard consent process. Conclusion: This randomized study of two novel consent interventions across six different clinical trials demonstrated a statistically significant difference in participant understanding based on overall scores among those exposed to the video intervention compared to those exposed to the standard consent.

Authors: Testa Edward J , Lemme Nicholas J , Li Lambert T , DeFroda Steven 
Published: April 2021

Background As total shoulder arthroplasty has emerged as the fastest growing joint replacement performed, optimizing surgical efficiency and patient outcomes is essential. The goals of the current study were to identify trends and factors affecting the operative time of total shoulder arthroplasty over a 10-year period. Methods The National Surgical Quality Improvement Program database was analyzed to determine the operative time and 30-day complications of total shoulder arthroplasty from 2008 to 2018. Factors affecting total shoulder arthroplasty operative time were also assessed. Multivariable linear regression was used to analyze operative time over years studied while controlling for patient demographics and comorbidities. Results A total of 20,587 total shoulder arthroplasty cases from 2008 to 2018 were included. Mean operative time in 2008 was 139.0 min, while in 2018, mean operative time decreased to 105.6 min (P < .001). Male sex, outpatient surgery, increased body mass index, and low preoperative hematocrit were associated with longer operative times, while elevated international normalized ratio, resident involvement, and elective surgeries were associated with decreased operative duration. Discussion Operative time for total shoulder arthroplasty has decreased from 2008 to 2018. Patient factors and comorbidities are associated with operative time, and such factors are important to consider in operative planning to ensure appropriate patient and surgeon expectations.

Published: April 2021

Background: Platelet-rich plasma (PRP) injections have been proposed as a biologic option to provide symptomatic relief and delay surgery in patients with degenerative joint disease of osteoarthritis (OA). The efficacy of autologous PRP on symptomatic degenerative meniscal lesions (DMLs) has never been investigated. Hypothesis: We hypothesized that patients with symptomatic DMLs without OA undergoing autologous PRP injections experience a significant clinical improvement at 12 months. Study Design: Prospective case series. Level of Evidence: Level 4. Methods: A total of 69 patients with symptomatic DMLs without radiographic evidence of knee OA (Kellgren-Lawrence radiographic grading scale 0-1) received 4 autologous PRP injections once a week. Patients were prospectively evaluated before the injection and then at 1, 3, 6, and 12 months. Evaluation was based on Lysholm knee scoring scale (primary outcome), Western Ontario and McMaster Universities Arthritis Index (WOMAC), Tegner activity scale, and visual analogue scale scores. Results: Patients treated with PRP injections demonstrated an improving knee function and symptoms over the duration of the study. A significant improvement from baseline to 12 months was observed in all the outcome measures, and no patients experienced failure or required surgery during the follow-up. Patients younger than 50 years reported lower subjective level of pain and higher Tegner activity scale at baseline and had significantly better Lysholm knee scoring scale ( P = 0.03) and WOMAC ( P = 0.03) scores at 6 months, as well as better range of motion at 3, 6, and 12 months ( P < 0.001). Thirty-three (47.8%) patients were very satisfied, 26 (37.7%) satisfied, 8 (11.6%) partially satisfied, and 2 (2.9 %) not satisfied, with 62 (89.8%) patients willing to repeat the same treatment. No patient was lost to follow-up and no patient experienced adverse reaction, infection, failure, recurrence or underwent further surgery. Conclusion: PRP injections provide short-term benefits in symptomatic DMLs. Although promising results were evident at 12 months, this is a preliminary study and no definitive recommendation can be made based, for example, on longer follow-up. Clinical Relevance: This research supports the use of autologous PRP injections for symptomatic DMLs.

Published: April 2021

Background: Amiodarone treatment is effective against various types of arrhythmias but is associated with adverse effects affecting, among other organs, thyroid function. Amiodarone-induced thyroid dysfunction was not thoroughly evaluated in children as it was in adults, yet this affection may lead to irreversible neurodevelopmental complications. Our study aimed to define the incidence and risk factors of amiodarone-induced thyroid dysfunction in children. Methods: The study was designed as an observational study with a retrospective clinical series of 152 children treated by amiodarone in the Pediatric Cardiology Unit of our center from 1990 to 2019. All patients were divided into three groups according to their thyroid status: euthyroid, AIH (amiodarone-induced hypothyroidism) or AIT (amiodarone-induced thyrotoxicosis). Patients from these three groups were compared in terms of key clinical and therapeutic features. Results: Amiodarone-induced thyroid dysfunction was present in 23% of patients. AIT (5.3%) was three times less common than AIH (17.7%), and its occurrence increased with older age ( p < 0.05), treatment dosage ( p < 0.05), treatment duration ( p < 0.05) and the number of loading doses administered ( p < 0.05). There were no distinctive clinical features between euthyroid and AIH groups. A multivariable prediction model of AIT was built, with a yield of 66.7% as positive predictive value and 96.7% as negative predictive value. Conclusion: We observed that one in five children developed amiodarone-induced thyroid dysfunction. Special attention is required for older children with a high dosage and long-term therapy and who received a large number of loading doses, since these children are at risk to develop AIT, which is more delicate to manage than AIH.

Published: April 2021

Background: Acute kidney injury (AKI) is a common complication of hospitalization with high morbidity and mortality for which no effective treatments exist and for which current diagnostic tools have limitations for earlier identification. MicroRNAs (miRNAs) are small non-coding RNAs that have been implicated in the pathogenesis of AKI, and some miRNAs have shown promise as therapeutic tools in animal models of AKI. However, less is known about the role of miRNAs in human AKI. Objective: To evaluate the role of miRNAs in human subjects with AKI. Design: Systematic review and meta-analysis Measurements: Quantification of miRNA levels from human blood, urine, or kidney biopsy samples, and measures of renal function as defined in the study protocol. Methods: A comprehensive search strategy for Ovid MEDLINE All, Embase, Web of Science, and CENTRAL will be developed to identify investigational studies that evaluated the relationship between miRNA levels and human AKI. Primary outcomes will include measurements of kidney function and miRNA levels. Study screening, review and data extraction will be performed independently by 2 reviewers. Study quality and certainty of evidence will be assessed with validated tools. A narrative synthesis will be included and the possibility for meta-analysis will be assessed according to characteristics of clinical and statistical heterogeneity between studies. Limitations: These include (1) lack of randomized trials of miRNAs for the prevention or treatment of human AKI, (2) quality of included studies, and (3) sources of clinical and statistical heterogeneity that may affect strength and reproducibility of results. Conclusion: Previous studies of miRNAs in different animal models of AKI have generated strong interest on their use for the prevention and treatment of human AKI. This systematic review will characterize the most promising miRNAs for human research and will identify methodological constraints from miRNA research in human AKI to help inform the design of future studies.
