Title: Which position in American Football is more likely to get you benched due to LEI? An Analysis of NFL Players injured in the years 2016-2020. Authors: Robert de la Torre, Abdullah Sahyouni, Kinan Sawar, Gautham Pavar, Cris J. Diaz Alvarenga, Shravan Morisetty, Justin Bennie, Bohdan Matsko, Niyaz Uddin, Olivia Pakula Introduction: In American Football, there are twenty-four different positional roles that a player may assume. Some positions are unique to offense, such as quarterback and wide receiver. Others are unique to defense, such as cornerback or linebacker. There are also unique positions such as kicker or punter. All of these positions have different roles on the field and thus, different kinesiological patterns. These differences may lead to a variation in LE injuries experienced by players in different positions. Due to the prevalence of LEI\u27s in the NFL, we wanted to look at the trends for different injuries to see if there is positional correlation. Methods: We examined the NFL’s weekly injury reports for seasons from 2016 to 2020, and recorded players with four different categories of lower extremity injuries (LEI): (Hamstring, Calves, Groin, or Quadricep). Both the positional data and the nature of the injury are presented on NFL.com. We are looking at the frequency of various injuries in relation to position, as well as injury timelines for the four different LE injury categories. Results: Data is available and pending analysis. Discussion: The data collected from this study may be beneficial for any athlete engaging in organized football. Individuals with a certain injury history can be made aware of the impact their specific roles on the field may have on their injury. This can be useful information for parents and coaching staff/trainers to be aware of. Injuries to key players can dramatically impede a football season\u27s success in both monetary and subjective terms

Predictors of Patient Satisfaction in Spine Surgery: A Systematic Review

Background: Recently, there has been increased interest in patient satisfaction measures such as Press Ganey and Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS) surveys. In this systematic review, the spine surgery literature is analyzed to evaluate factors predictive of patient satisfaction as measured by these surveys. Methods: A thorough literature search was performed in PubMed/MEDLINE, Google Scholar, and Cochrane databases. All English-language articles from database inception to July 2020 were screened for study inclusion according to PRISMA guidelines. Results: Twenty-four of the 1899 published studies were included for qualitative analysis. There has been a statistically significant increase in the number of publications across years (P = 0.04). Overall, the studies evaluated the relationship between patient satisfaction and patient demographics (71%), preoperative and intraoperative clinical factors (21%), and postoperative factors (33%). Top positive predictors of patient satisfaction were patient and nursing/medical staff relationship (n = 4; 17%), physician–patient relationship (n = 4; 17%), managerial oversight of received care (n = 3; 13%), same sex/ethnicity between patient and physician (n = 2; 8%), and older age (n = 2; 8%). Top negative predictors of patient satisfaction were high Charlson Comorbidity Index/high disability/worse overall health functioning (n = 7; 29%), increased length of hospital stay (n = 4; 17%), high rating for pain/complications/readmissions (n = 4; 17%), and psychosocial factors (n = 3; 13%). Conclusions: There is heterogeneity in terms of different factors, both clinical and nonclinically related, that affect patient satisfaction ratings. More research is warranted to investigate the role of hospital consumer surveys in the spine surgical patient population

Imaging fascicular organization of rat sciatic nerves with fast neural electrical impedance tomography

Imaging compound action potentials (CAPs) in peripheral nerves could help avoid side effects in neuromodulation by selective stimulation of identified fascicles. Existing methods have low resolution, limited imaging depth, or are invasive. Fast neural electrical impedance tomography (EIT) allows fascicular CAP imaging with a resolution of <200 µm, <1 ms using a non-penetrating flexible nerve cuff electrode array. Here, we validate EIT imaging in rat sciatic nerve by comparison to micro-computed tomography (microCT) and histology with fluorescent dextran tracers. With EIT, there are reproducible localized changes in tissue impedance in response to stimulation of individual fascicles (tibial, peroneal and sural). The reconstructed EIT images correspond to microCT scans and histology, with significant separation between the fascicles (p < 0.01). The mean fascicle position is identified with an accuracy of 6% of nerve diameter. This suggests fast neural EIT can reliably image the functional fascicular anatomy of the nerves and so aid selective neuromodulation

Efficacy of steroid‐eluting stents in management of chronic rhinosinusitis after endoscopic sinus surgery: updated meta‐analysis

BackgroundRecently, there has been mounting evidence suggesting the efficacy of steroid-eluting stents (SES) for management of chronic rhinosinusitis after endoscopic sinus surgery (ESS). This meta-analysis serves to evaluate the efficacy of SES in improving postoperative outcomes after ESS.MethodsA systematic literature search was performed of PubMed for articles published between 1985 and 2018. The outcome variables were reported at, on average, 30 days postintervention.ResultsSeven of the 76 published studies, all of which were industry-sponsored, were included for a collective cohort of 444 SES and 444 control sinuses. In patients who received SES vs controls, collective odds ratios (ORs) for postoperative need for intervention, surgery, and oral steroid were 0.45 (95% confidence interval [CI], 0.33-0.62; p &lt; 0.001), 0.30 (95% CI, 0.18-0.52; p &lt; 0.001), and 0.58 (95% CI, 0.40-0.84; p = 0.004), respectively. In addition, collective ORs for frontal sinus ostia (FSO) patency, moderate-to-severe adhesion/scarring, and increase in polyp score were 2.53 (95% CI, 1.61-3.97; p &lt; 0.001), 0.28 (95% CI, 0.13-0.59; p &lt; 0.001), and 0.42 (95% CI, 0.25-0.74; p = 0.002), respectively. Collective mean differences for FSO/ethmoid inflammation and FSO diameter were -10.86 mm (p &lt; 0.001) and +1.34 mm (p &lt; 0.001), respectively.ConclusionAggregate evidence suggests that SES can improve ESS outcomes by reducing rates of postoperative intervention and recurrent polyposis and inflammation, while promoting FSO patency. All included and analyzed studies were industry-sponsored and ruling-out publication bias was not possible. Future independent and nonsponsored studies to further evaluate SES's long-term efficacy are warranted

Hyams grading as a predictor of metastasis and overall survival in esthesioneuroblastoma: a meta-analysis.

BACKGROUND:Esthesioneuroblastoma (ENB), also known as olfactory neuroblastoma, represents up to 3% of all sinonasal neoplasms. Hyams histologic grading is a promising tool in predicting metastases and establishing prognoses for this complex tumor. METHODS:A systematic literature search was performed in the PubMed, Ovid MEDLINE, and Cochrane databases. ENB patients with Hyams I-II or III-IV were categorized as low-grade Hyams (LGH) or high-grade Hyams (HGH), respectively. Binary and continuous random-effects models were applied to calculate odds ratios (ORs) for the incidences of neck and distal metastases as well as for 5- and 10-year overall survival rates. RESULTS:Of the 57 screened articles published from 1993 to 2018, 16 (525 patients) and 21 (563 patients) provided data for tumor metastases and overall survival rates, respectively. Neck metastasis was observed in 18.2% of HGH vs 7.9% of LGH patients. Distant metastasis was noted in 20.7% of HGH vs 8.9% of LGH patients. LGH patients had 5- and 10-year overall survival rates of 81.2% and 64.0%, respectively, as compared with 60.9% and 40.6%, respectively, for HGH patients. In comparing HGHs vs LGHs, the collective ORs for neck and distant metastases were 2.08 (95% confidence interval [CI], 1.09-3.99; p = 0.03) and 2.37 (95% CI, 1.07-5.26; p = 0.03), respectively. Moreover, in comparing LGHs vs HGHs, collective ORs for 5- and 10-year overall survival rates were 3.39 (95% CI, 2.09-5.49; p &lt; 0.001) and 3.03 (95% CI, 1.82-5.06; p &lt; 0.001), respectively. CONCLUSION:HGH ENBs, compared with LGH ENBs, are more likely to metastasize to neck or distal targets and to have lower overall survival rates

The Current State of Radiotherapy for Pediatric Brain Tumors: An Overview of Post-Radiotherapy Neurocognitive Decline and Outcomes.

Tumors of the central nervous system are the most common solid malignancies diagnosed in children. While common, they are also found to have some of the lowest survival rates of all malignancies. Treatment of childhood brain tumors often consists of operative gross total resection with adjuvant chemotherapy or radiotherapy. The current body of literature is largely inconclusive regarding the overall benefit of adjuvant chemo- or radiotherapy. However, it is known that both are associated with conditions that lower the quality of life in children who undergo those treatments. Chemotherapy is often associated with nausea, emesis, significant fatigue, immunosuppression, and alopecia. While radiotherapy can be effective for achieving local control, it is associated with late effects such as endocrine dysfunction, secondary malignancy, and neurocognitive decline. Advancements in radiotherapy grant both an increase in lifetime survival and an increased lifetime for survivors to contend with these late effects. In this review, the authors examined all the published literature, analyzing the results of clinical trials, case series, and technical notes on patients undergoing radiotherapy for the treatment of tumors of the central nervous system with a focus on neurocognitive decline and survival outcomes
