RESUMO

BACKGROUND AND PURPOSE: Incidental findings are discovered in neuroimaging research, ranging from trivial to life-threatening. We describe the prevalence and characteristics of incidental findings from 16,400 research brain MRIs, comparing spontaneous detection by nonradiology scanning staff versus formal neuroradiologist interpretation. MATERIALS AND METHODS: We prospectively collected 16,400 brain MRIs (7782 males, 8618 females; younger than 1 to 94 years of age; median age, 38 years) under an institutional review board directive intended to identify clinically relevant incidental findings. The study population included 13,150 presumed healthy volunteers and 3250 individuals with known neurologic diagnoses. Scanning staff were asked to flag concerning imaging findings seen during the scan session, and neuroradiologists produced structured reports after reviewing every scan. RESULTS: Neuroradiologists reported 13,593/16,400 (83%) scans as having normal findings, 2193/16,400 (13.3%) with abnormal findings without follow-up recommended, and 614/16,400 (3.7%) with "abnormal findings with follow-up recommended." The most common abnormalities prompting follow-up were vascular (263/614, 43%), neoplastic (130/614, 21%), and congenital (92/614, 15%). Volunteers older than 65 years of age were significantly more likely to have scans with abnormal findings (P < .001); however, among all volunteers with incidental findings, those younger than 65 years of age were more likely to be recommended for follow-up. Nonradiologists flagged <1% of MRIs containing at least 1 abnormality reported by the neuroradiologists to be concerning enough to warrant further evaluation. CONCLUSIONS: Four percent of individuals who undergo research brain MRIs have an incidental, potentially clinically significant finding. Routine neuroradiologist review of all scans yields a much higher rate of significant lesion detection than selective referral from nonradiologists who perform the examinations. Workflow and scan review processes need to be carefully considered when designing research protocols.

RESUMO

BACKGROUND: Uterine clear cell carcinoma is a rare and aggressive subtype of endometrial carcinoma. Prospective clinical trials have not been feasible for this rare tumor, and data regarding the optimal adjuvant treatment regimen for early-stage uterine clear cell carcinomas is limited. Our study's objective was to determine if adjuvant chemotherapy or radiation therapy improves patients' outcomes in stage I and II uterine clear cell carcinoma. METHODS: Patients with stage I and II uterine clear cell carcinoma were identified at a single institution. All cases were reviewed by a gynecologic pathologist. Both pure and mixed non-serous uterine clear cell carcinomas were included. Primary outcomes were recurrence free survival and overall survival. RESULTS: A total of 71 patients were identified including 39 (55%) pure and 32 (45%) mixed clear cell carcinoma. Most patients were FIGO stage IA (77.5%). Most patients (n = 58, 82%) received adjuvant therapy, including 43 (61%) receiving chemotherapy, 50 (70%) receiving radiation therapy, and 35 (49%) receiving both. Recurrence free survival was not significantly different among patients receiving no or <6 cycles of chemotherapy versus patients receiving 6 cycles of chemotherapy (p = 0.39). However, median OS was significantly different among patients receiving no or <6 cycles of chemotherapy versus 6 cycles of chemotherapy (p = 0.004). On univariable analysis, 6 cycles of chemotherapy was significantly associated with improved OS (HR 0.1, 95% CI 0.01-0.07). Presence of LVSI, mutated p53, number of pelvic and para-aortic lymph nodes assessed, adjuvant chemotherapy (any number of cycles), and >2 medical co-morbidities were not significant predictors of OS on univariable analysis. On multivariable analysis, 6 cycles of adjuvant chemotherapy remained a significant predictor of improved OS (HR 0.1, 95% CI 0.01-0.8). CONCLUSIONS: In this study, administration of 6 cycles of chemotherapy appears to significantly improve OS. This finding suggests consideration of 6 cycles of adjuvant chemotherapy in patients with early-stage uterine clear cell carcinoma, however clinical trials are needed to confirm these findings.

RESUMO

PURPOSE: To evaluate the changes in mental health, quality of life (QOL) and physical activity (PA) among adolescent athletes during the COVID-19 pandemic as organised sports resumed. METHODS: Adolescent athletes completed surveys including demographic and sport participation information, 7-item Generalized Anxiety Disorder, 9-item Patient Health Questionnaire, Pediatric Quality of Life Inventory and the Hospital for Special Surgery Pediatric Functional Activity Brief Scale in May 2020 following COVID-19-related sport cancellations (Spring20) and after returning to sports in May 2021 (Spring21). The groups were balanced by inverse propensity score weighting and compared using analysis of variance models and ordinal regression models. RESULTS: 17 421 participants were included (Spring20=13 002; Spring21=4419; 16.2±1.2 years; 53% female). Anxiety was significantly lower (better) in Spring21 (Spring20=7.0, 95% CI 6.9 to 7.1; Spring21=4.9, 95% CI 4.8 to 5.0, p<0.001), as was the prevalence of moderate to severe anxiety (Spring20=29.4%, Spring21=17.1%, p<0.001). Depression was significantly improved in Spring21 (Spring20=7.6, 95% CI 7.5 to 7.7; Spring21=4.6, 95% CI 4.5 to 4.8, p<0.001), as was the prevalence of moderate to severe depression (Spring20=32.2%, Spring21=15.4%, p<0.001). Athletes in Spring21 reported higher QOL (Spring20=79.6, 95% CI 79.3 to 79.9; Spring21=84.7, 95% CI 84.4 to 85.0, p<0.001) and increased levels of PA (Spring20=13.8, 95% CI 13.6 to 13.9; Spring21=22.7, 95% CI 22.6 to 22.9, p<0.001). CONCLUSION: Early COVID-19 sports restrictions were associated with worsening mental health in adolescents. In 2021, after returning to sports, athletes reported significant improvements in mental health, QOL and PA, although mental health adversities remain an important priority.

RESUMO

There has been a long history of human usage of the biologically-active phytochemicals in Salvia rosmarinus, Zingiber officinale, and Sophora japonica for health purposes, and we recently reported on a combination of those plant materials as the PB123 dietary supplement. In the present work we extended those studies to evaluate activation of the nuclear factor erythroid 2-related factor 2 (Nrf2) transcription factor and differential gene expression in cultured HepG2 (hepatocellular carcinoma) cells treated with PB123. We determined transcriptome changes using mRNA-seq methods, and analyzed the affected pathways using Ingenuity Pathway Analysis and BioJupies, indicating that primary effects included increasing the Nrf2 pathway and decreasing the cholesterol biosynthesis pathway. Pretreatment of cultured HepG2 cells with PB123 upregulated Nrf2-dependent cytoprotective genes and increased cellular defenses against cumene hydroperoxide-induced oxidative stress. In contrast, pretreatment of cultured HepG2 cells with PB123 downregulated cholesterol biosynthesis genes and decreased cellular cholesterol levels. These findings support the possible beneficial effects of PB123 as a healthspan-promoting dietary supplement.

RESUMO

AIMS: Substantial lymphovascular space invasion (LVSI) compared with none or focal LVSI is predictive of lymph node involvement and worse clinical outcomes in endometrioid-type endometrial carcinoma. We aimed to quantify the incidence of substantial LVSI in type II (clear cell and serous) endometrial cancer and correlate the extent of LVSI with clinical outcomes. MATERIALS AND METHODS: A retrospective review was conducted on type II endometrial cancer patients who underwent surgical management from July 2017 to December 2019 using the three-tier LVSI scoring system. Binary logistic regression and Cox regression were used to analyse predictors of lymph node involvement or survival outcomes, respectively. The Kaplan-Meier method and Log-rank test were used to analyse differences in locoregional disease-free survival (LR-DFS), distant metastasis disease-free survival (DM-DFS) and overall survival between patients with substantial versus none/focal LVSI. RESULTS: In 79 patients with type II endometrial carcinoma, no LVSI, focal LVSI and substantial LVSI was present in 48.1%, 15.2% and 36.7% of patients, respectively. Lymph nodes were involved in 0.0% with no LVSI, 20.0% with focal LVSI and 60.0% with substantial LVSI (P < 0.001). The median follow-up was 22.2 months. In patients with none/focal versus substantial LVSI, the 2-year LR-DFS and DM-DFS rates were 91.5% versus 71.4% (P = 0.01) and 90.2% versus 63.8% (P = 0.005), respectively. On univariate analysis, myometrial invasion ≥50%, tumour size ≥3.6 cm, substantial versus none/focal LVSI, lymph node involvement and omission of adjuvant radiotherapy were significant predictors for worse LR-DFS and DM-DFS (P < 0.05). DISCUSSION: Substantial LVSI has a high incidence in type II pathology at our institution and predicts for lymph node involvement and worse clinical outcomes.

RESUMO

CONTEXT: During the fall of 2020, some high schools across the United States allowed their students to participate in interscholastic sports while others cancelled or postponed their sport programs due to concerns regarding COVID-19 transmission. What effect this has had on the physical and mental health of adolescents is unknown. OBJECTIVE: To identify the effect of playing a sport during the COVID-19 pandemic on the health of student-athletes. DESIGN: Cross-sectional study. SETTING: Sample recruited via email. PATIENTS OR OTHER PARTICIPANTS: A total of 559 Wisconsin high school athletes (age = 15.7 ± 1.2 years, female = 43.6%, male = 56.4%) from 44 high schools completed an online survey in October 2020. A total of 171 (30.6%) athletes played (PLY) a fall sport, while 388 (69.4%) did not play (DNP). MAIN OUTCOME MEASURE(S): Demographic data included sex, grade, and sport(s) played. Assessments were the General Anxiety Disorder-7 Item for anxiety, Patient Health Questionnaire-9 Item for depression, the Hospital for Special Surgery Pediatric Functional Activity Brief Scale for physical activity, and the Pediatric Quality of Life Inventory 4.0 for quality of life. Univariable comparisons between the 2 groups were made via t tests or χ2 tests. Means for each continuous outcome measure were compared between groups using analysis-of-variance models that controlled for age, sex, teaching method (virtual, hybrid, or in person), and the percentage of students eligible for free or reduced-price lunch. RESULTS: The PLY group participants were less likely to report moderate to severe symptoms of anxiety (PLY = 6.6%, DNP = 44.1%, P < .001) and depression (PLY = 18.2%, DNP = 40.4%, P < .001). They also demonstrated higher (better) Pediatric Functional Activity Brief Scale scores (PLY = 23.2 [95% CI = 22.0, 24.5], DNP = 16.4 [95% CI = 15.0, 17.8], P < .001) and higher (better) Pediatric Quality of Life Inventory total scores (PLY = 88.4 [95% CI = 85.9, 90.9], DNP = 79.6 [95% CI = 76.8, 82.4], P < .001). CONCLUSIONS: Adolescents who played a sport during the COVID-19 pandemic described fewer symptoms of anxiety and depression and had better physical activity and quality-of-life scores compared with adolescent athletes who did not play a sport.

RESUMO

PURPOSE: Tumor molecular analyses in endometrial cancer (EC) includes 4 distinct subtypes: (1) POLE-mutated, (2) mismatch repair protein (MMR) deficient, (3) p53 mutant, and (4) no specific molecular profile. Recently, a sub-analysis of PORTEC-3 demonstrated notable differences in treatment response between molecular classification (MC) groups. Cost of testing is one barrier to widespread adoption of MC. Therefore, we sought to determine the cost-effectiveness of MC in patients with stage I and II high-risk EC. METHODS: A Markov decision model was developed to compare tumor molecular classification (TMC) vs. no testing (NT). A healthcare payor's perspective and 5-year time horizon were used. Base case data were abstracted from PORTEC-3 and the molecular sub-analysis. Cost and utility data were derived from public databases, peer-reviewed literature, and expert input. Strategies were compared using the incremental cost-effectiveness ratio (ICER) with effectiveness in quality-adjusted life years (QALYs) and evaluated with a willingness-to-pay threshold of $100,000 per QALY gained. Sensitivity analyses were performed to test model robustness. RESULTS: When compared to NT, TMC was cost effective with an ICER of $25,578 per QALY gained; incremental cost was $1780 and incremental effectiveness was 0.070 QALYs. In one-way sensitivity analyses, results were most sensitive to the cost of POLE testing, but TMC remained cost-effective over all parameter ranges. CONCLUSIONS: TMC in early-stage high-risk EC is cost-effective, and the model results were robust over a range of parameters. Given that MC can be used to guide adjuvant treatment decisions, these findings support adoption of TMC into routine practice.

RESUMO

The clinical application of intraoperative mechanical ventilation is highly variable and often determined by providers' attitudes and preferences, rather than evidence. Ventilation strategies using high tidal volumes (VT) with little to no positive end-expiratory pressure (PEEP) are associated with lung injury, increasing the risk of postoperative pulmonary complications. Literature demonstrates that applying lung protective ventilation (LPV) strategies intraoperatively, including low VT, individualized PEEP, and alveolar recruitment maneuvers, can reduce the risk of postoperative pulmonary complications. This multicenter quality improvement project aimed to develop and implement an LPV protocol to increase nurse anesthetists' knowledge and adherence to LPV strategies in adults undergoing laparoscopic cholecystectomy. The anesthesia providers were educated about LPV strategies and their intraoperative application to individualize ventilation settings based on patient comorbidities and body habitus. Adherence was determined by collecting ventilator data and evaluating the data using logistic regression. The overall protocol adherence significantly increased (P=.01). Additionally, there was a significant improvement in adherence to each individual component of the protocol (all P<.05) except for VT. Decreasing the oxygen concentration administered during maintenance and emergence was the most commonly adopted practice (P<.0001). This project demonstrates that education and a standardized protocol can increase the use of intraoperative LPV strategies.

RESUMO

AIMS: There are limited data in endometrial cancer for nodal control and appropriate treatment volume for non-surgically resected nodes treated with chemoradiotherapy (CRT) for patients who are not candidates for upfront extrafascial hysterectomy. MATERIALS AND METHODS: Patients (n = 105) with clinical stage ≥ II endometrial cancer who were not candidates for upfront extrafascial hysterectomy treated with preoperative CRT were retrospectively reviewed. CRT included pelvic nodes to the common iliac for node-negative disease and para-aortic nodes to the renal vessel for any node-positive disease. Involved nodes most commonly received a boost of 55 Gy in 25 fractions ± additional 4-6 Gy sequential boost for nodes >2 cm. RESULTS: Of the included 95 patients, 55 patients were node positive, with a total of 300 positive nodes. At a median follow-up of 25 months (interquartile range 9-46), the 3-year regional control was 91%. The 3-year involved nodal control rate was 96%. Involved nodal control was significantly higher in type I histology, nodes <2 cm and by radiation dose (75% for <55 Gy, 98% for 55 Gy in 25 fractions and 89% for >55 Gy, P = 0.03). The 3-year para-aortic failure rate for node negative patients treated with pelvis-only CRT was significantly higher with positron emission tomography/computed tomography (PET/CT) versus computed tomography (CT)-based staging (0% versus 20%). CONCLUSION: This is the largest study examining regional control rates of involved lymph nodes with CRT for patients who were not candidates for upfront extrafascial hysterectomy. Nodal failure was low following CRT and dose ≥55 Gy in 25 fractions seems to be adequate for involved nodes.

RESUMO

PURPOSE: The Vienna and Venezia (Elekta) are hybrid intracavitary/interstitial brachytherapy (BT) applicators for cervical cancers unsuitable for intracavitary BT alone to improve target coverage or reduce critical organ dose. There is limited outcome data with the use of these applicators outside published experience of the EMBRACE group. We report feasibility and early outcomes with the use of these hybrid applicators at our institution. METHODS AND MATERIALS: Hybrid applicators were used to treat 61 patients with cervical cancer from November 2011 to December 2019. Indications for hybrid applicator use were involvement of the vagina in 10 patients (16%), residual central or parametrial disease in 46 patients (75%), and a narrow introitus in 5 patients (9%). Toxicities were graded using the CTCAE v4.0. Outcomes were assessed with the Kaplan-Meier method. RESULTS: Median follow-up was 16 months (IQR 9-32 mos). Median HRCTV volume was 31.6 cm3 (IQR 25-48 cm3). Median HRCTV D90 was 86.1 Gy (IQR 84.3-88.0 Gy). In 54 patients with follow-up PET/CT at 3 months, complete initial imaging response locally was seen in 46 patients.Estimated 12-month Kaplan-Meier overall survival, locoregional control, distant control, and recurrence-free survival estimates were 86.9%, 80.6%, 73.8%, and 65.9%, respectively. The 12-month incidence of Grade 3+ GI/GU chronic toxicities was 5.7%, consisting of vesicovaginal fistula, rectovaginal fistula, and ureterovesical fistula. CONCLUSIONS: Our single-institution data support the use of the hybrid applicators, as an alternative to traditional BT applicators when clinically warranted. Use of hybrid applicators is feasible with adequate coverage of disease in the vagina and parametrium.

RESUMO

Vertebral compression fractures (VCFs) result from either trauma or a pathologic process that weakens the bone by conditions such as osteoporosis or tumor. The incidence of VCFs has been rising over the last few decades in accordance with the aging population. These fractures can result in severe pain, physical limitation and disability, as well as increased morbidity and mortality. Patients with VCFs are optimally treated by accurate and early diagnosis and treatment. An effective method to treat these fractures is percutaneous vertebral augmentation, which is a set of minimally invasive procedures that stabilizes osseous fractures, provides immediate pain relief, and improves quality of life. Vertebral augmentation procedures include vertebroplasty, kyphoplasty, and vertebral augmentation with implants. Each of these techniques is described in general terms in this article. The ideal candidate for vertebral augmentation is a patient with a symptomatic fracture seen on cross-sectional imaging in which nonsurgical management has failed and has positive signs on physical examination with no absolute contraindication. This procedure should be done with the appropriate equipment and personnel in a facility designed for this purpose. After the procedure, the patient should undergo the appropriate follow-up to ensure optimal recovery. Additionally, it is essential that the patient receives appropriate therapy for the underlying disorder that predisposed them to the vertebral fracture.

RESUMO

OBJECTIVES: A pooled analysis of PORTEC-1 & 2 identified substantial lymphovascular space invasion (LVSI) in 4.8% of patients, which predicted for pelvic recurrence, distant metastasis, and overall survival. Our institution implemented the PORTEC three-tier system of LVSI reporting (absent, focal, or substantial). We aimed to quantify the incidence of substantial LVSI in a North American population and to correlate extent of LVSI with lymph node (LN) involvement. METHODS: A retrospective review was conducted on patients with clinically uterine-confined, endometrioid type endometrial cancer who underwent surgical staging and were found to have pT1a-b disease. Binary logistic regression was used to assess predictors of LN involvement (defined as ITC, micrometastases, or macrometastases). RESULTS: In total, 438 patients with pT1a-b disease were identified. In the overall cohort and in the subset meeting PORTEC-1 inclusion criteria (n = 195), no LVSI was present in 67.4% and 50.8%; focal LVSI was present in 16.7% and 24.1%; and substantial LVSI was present in 16.0% and 25.1%, respectively. Among patients who underwent surgical LN assessment (79.2%, n = 347), LNs were involved in 3.3% without LVSI, 7.5% with focal LVSI (OR 2.4), and 15.2% with substantial LVSI (OR 5.3) (p = .005), with a similar trend in the PORTEC-1 cohort. Extent of LVSI correlated with disease burden in LN metastases. CONCLUSION: Our incidence of substantial LVSI was three to five times higher than reported by PORTEC and correlated with LN involvement. This questions the reproducibility of the three-tier LVSI reporting system and emphasizes the need for multi-institutional data outside PORTEC for confirmation of our findings.

RESUMO

BACKGROUND: Injury epidemiology for boys' high school contact and collision sport has been described in several overlapping but fragmented studies. Comprehensive comparisons of injuries sustained in boys' soccer, wrestling, football, ice hockey, and lacrosse are lacking. PURPOSE: To describe patterns of injury by severity, body site, and diagnosis among high school boys' contact and collision sports in the United States. STUDY DESIGN: Descriptive epidemiology study. METHODS: Injury rates and rate ratios (RRs) were calculated for injuries sustained in boys' high school soccer, wrestling, football, ice hockey, and lacrosse through use of the High School RIO (Reporting Information Online) surveillance data from 2008-2009 through 2012-2013. Injury patterns were described by site, diagnosis, time loss, and severity. Severe injury was defined as an injury that resulted in 21 days or more of time loss from sport participation. Risk of sustaining a concussion was compared between sports. RESULTS: The risk of sustaining an injury was higher in competition compared with practice overall (RR, 4.01; 95% CI, 3.90-4.12); the same pattern was true for severe injuries (RR, 4.61; 95% CI, 4.34-4.90). Football players experienced the highest injury rate (3.87 per 1000 athlete-exposures [AEs]) and the highest severe injury rate (0.80 per 1000 AEs). Overall, the most commonly injured body site was the head/face (22.5%), and the most prevalent injury diagnosis was ligament sprain not requiring surgery (23.5%). The most frequently injured body site from severe injury was the knee (24.6%), and fracture or avulsion was the most prevalent severe injury diagnosis (37.0%). Football players had a significantly higher risk of sustaining a concussion compared with other contact or collision sport athletes (P < .05). CONCLUSION: Injuries rates were higher in competition than those in practice for boys' high school contact and collision athletes. Football players sustained the highest injury rate, the highest severe injury rate, and the highest concussion rate among the sports included in this analysis. Understanding these patterns of injury can generate policy and rule changes to make sports safer and maintain high levels of participation.

RESUMO

Bioactive phytochemicals in Rosmarinus officinalis, Withania somnifera, and Sophora japonica have a long history of human use to promote health. In this study we examined the cellular effects of a combination of extracts from these plant sources based on specified levels of their carnosol/carnosic acid, withaferin A, and luteolin levels, respectively. Individually, these bioactive compounds have previously been shown to activate the nuclear factor erythroid 2-related factor 2 (Nrf2) transcription factor, which binds to the antioxidant response element (ARE) and regulates the expression of a wide variety of cytoprotective genes. We found that combinations of these three plant extracts act synergistically to activate the Nrf2 pathway, and we identified an optimized combination of the three agents which we named PB125 for use as a dietary supplement. Using microarray, quantitative reverse transcription-PCR, and RNA-seq technologies, we examined the gene expression induced by PB125 in HepG2 (hepatocellular carcinoma) cells, including canonical Nrf2-regulated genes, noncanonical Nrf2-regulated genes, and genes which appear to be regulated by non-Nrf2 mechanisms. Ingenuity Pathway Analysis identified Nrf2 as the primary pathway for gene expression changes by PB125. Pretreatment with PB125 protected cultured HepG2 cells against an oxidative stress challenge caused by cumene hydroperoxide exposure, by both cell viability and cell injury measurements. In summary, PB125 is a phytochemical dietary supplement comprised of extracts of three ingredients, Rosmarinus officinalis, Withania somnifera, and Sophora japonica, with specified levels of carnosol/carnosic acid, withaferin A, and luteolin, respectively. Each ingredient contributes to the activation of the Nrf2 pathway in unique ways, which leads to upregulation of cytoprotective genes and protection of cells against oxidative stress and supports the use of PB125 as a dietary supplement to promote healthy aging.

RESUMO

PURPOSE: Human papillomavirus (HPV) is implicated as a causative factor in vulvar squamous cell carcinoma (VSCC). This study evaluates if p16-positivity, a surrogate for HPV, predicts for better response rates to chemoradiation therapy and survival. MATERIALS AND METHODS: We conducted a retrospective chart review of women treated with neoadjuvant or definitive chemoradiation (CRT) therapy from 2000 to 2016 for VSCC. p16 stain-positivity was defined as diffuse strong "block" immunoreactivity within invasive tumor. RESULTS: Seventy-three women with median follow-up of 13.4 months were analyzed. Thirty-three (45.2%) had p16+ tumors. Median age was 73 years (range: 37-89); with p16+ tumors, the median age was 60 years vs 73 years for women with p16- tumors (p < 0.001). The distribution of tumor size and stage by p16-status were similar. The complete clinical response (cCR) rate for p16+ tumors was 63.6% vs 35.0% for p16- tumors (p = 0.014). The pathologic complete response (pCR) rate for women treated neoadjuvantly was 53.8% vs 31.4% for p16+ vs p16-, respectively (p = 0.067). The combined complete response (cCR orpCR [CCR]) rate was 63.6% for p16+ and 30.0% for p16- (p = 0.004). Two-year vulvar control (VC) for women with p16+ tumors was 75.5% vs. 49.5% for p16- (p = 0.008). In women with p16+ tumors who achieved CCR, 2-year VC was 92.3% vs 52.1% for CIR (p = 0.009). For p16- tumors, 2-year VC was 67.3% vs 41.1% for CCR and CIR (p = 0.072). No woman with a p16+ tumor developed distant metastases vs. 7 with p16- tumor (p = 0.013). OS was not statistically different between p16+ cohorts, but was improved for p16- patients with CR vs CIR, 72.9% vs 18.8% (p = 0.026). CONCLUSIONS: p16-positive tumors appear to have better clinical and pathologic response rates and clinical outcomes.

RESUMO

Introduction Patients who experience a transient ischaemic attack are at the highest risk of having a subsequent stroke immediately after their symptoms. A carotid endarterectomy should be performed on symptomatic, surgically suitable patients who present with a greater than 50% North American Symptomatic Carotid Endarterectomy Trial stenosis of the internal carotid artery within 2 weeks of their symptoms. This study aimed to determine whether the effectiveness of the carotid endarterectomy pathway has been impacted by the centralisation of vascular surgical services in the Bath, Bristol and Weston area. Materials and Methods From October 2013 to October 2015, critical steps in the patient carotid endarterectomy pathway that vascular surgeons from the Royal United Hospital Bath, Bristol Royal Infirmary and North Bristol NHS Trust input into the Royal College of Surgeons National Vascular Registry were collected. The dates of patient's symptoms, referral, first scan, surgical team review and surgery were analysed. Results Carotid endarterectomy data was collected for 261 patients. Overall, no significant difference in median time (days) from symptom to surgery from precentralisation data compared with post-centralisation data was seen (P = .175), with 65% patients meeting the national target of symptom to surgery in less than 14days. Discussion and Conclusion Centralisation has not significantly impacted the overall efficiency of the carotid endarterectomy pathway. This study highlights areas where improvement across the vascular network is required. This includes addressing the 35% patients that are not currently meeting the 14-day target and standardising the provision of care to outlying communities. Further follow-up is required to assess the longer term effects of centralisation.

RESUMO

PURPOSE: To describe the prevalence of anemia among incoming female college athletes and to characterize the results and expenses of iron-related testing at one National Collegiate Athletic Association Division I institution. METHODS: In this retrospective medical record review, hemoglobin (Hgb) and ferritin laboratory values were obtained for student-athletes at a single institution, 2002 to 2014. Laboratories were collected either as part of the preparticipation examination (PPE) for female athletes, routine screening for cross-country athletes, or as needed for medical evaluation. Anemia was defined as Hgb < 11.6 g·dL for females and < 13.6 g·dL for male athletes. Iron deficiency was defined as Fer < 20 ng·mL for both sexes. RESULTS: A total of 5674 laboratory draws were obtained for 2749 individuals (56% female) from 25 different teams. The prevalence of low Hgb among female athletes at PPE was 5.7% (95% confidence interval, 4.4%-6.9%). At PPE, the incidence of anemia was not significantly higher for any sport when compared with the group mean. Ferritin and Hgb were collected together in approximately one third of all blood draws from females (n = 1059) and one sixth of blood draws from males (n = 411). For female athletes, 2.2% indicated iron deficiency anemia and 30.9% indicated iron deficiency without anemia. For male athletes, 1.2% indicated iron deficiency anemia and 2.9% indicated iron deficiency without anemia. The median cost of iron testing exceeded US $20,000 annually for the institution. CONCLUSIONS: One in 20 incoming female athletes was identified with anemia at the PPE. Given the costs of testing, screening practices at each institution should be thoughtfully selected and routinely reassessed.

RESUMO

BACKGROUND: The differential diagnosis for chest pain in the emergency department is broad and includes both benign and life-threatening conditions-with pericardial cyst as a rare example. Emergency physician-performed point-of-care focused cardiac ultrasound (FOCUS) is increasingly recognized as a useful modality in the evaluation of patients with chest pain. CASE REPORT: We report a case of hemorrhagic pericardial cyst in a young woman presenting with chest pain in which findings on FOCUS contradicted findings on chest x-ray study and thus, accelerated diagnosis and definitive treatment. We also comment on epidemiology, pathophysiology, clinical presentation, diagnosis, and management of this uncommon, potentially fatal cause of chest pain. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: This case report aims to bring an uncommon case to the attention of emergency providers and emphasize the importance of facility with FOCUS. Although definitive diagnosis and management were not accomplished at the bedside in this case, an abnormal finding on FOCUS prompted further investigation and timely treatment.

RESUMO

OBJECTIVES: Delayed discharges are a significant problem for the National Health Service. The objectives of this study were to determine the prevalence and impact of delayed discharge at a single specialist vascular surgery ward. DESIGN: A cross-sectional observational study. SETTING: A single specialist vascular unit in the UK during a 4-month study period (01/09/2014-31/12/2014). PARTICIPANTS: All patients admitted to the ward during the study period were included. Patients spending ≥1 night on the ward once declared medically fit for discharge (MFFD) were prospectively identified and data prospectively collected. All other patients were identified retrospectively with data collected retrospectively from electronic records. OUTCOME MEASURES: Primary outcome was number of patients experiencing delayed discharge. Secondary outcome measures were length of stay, length of delay and cost of delay. RESULTS: There were 268 admissions with a total length of stay (LoS) of 2776 days. 57 admissions (21.3%) experienced delayed discharges with a total 535 excess bed days (19.3% total LoS) once MFFD. Unplanned admission (relative risk 7.3 (95% CI 2.7 to 20.0; p<0.001)) and index amputation (relative risk 9.2 (95% CI 3.8 to 22.0; p<0.001)) were associated with increased risk of delayed discharge. There were significant differences in the length of delay by the reason for the delay (p=0.01). Delay due to the provision of social services and inpatient rehabilitation were associated with longer length of delay (post hoc analysis). Age was not independently associated with either increased risk of delayed discharge or length of delay.The total estimated cost of delayed discharges during the study period was £146 055. CONCLUSIONS: A significant number of vascular patients experience delayed discharge. MFFD vascular patients occupy a high proportion of vascular beds at considerable financial cost. Unplanned admissions, amputees and those delayed due to social services contributed most to delays. Closer integration with community health and social care providers may reduce delays.
