USE OF VISCOELASTIC COAGULATION TESTING IN MEGACHIROPTERA (PTEROPUS HYPOMELANUS AND PTEROPUS VAMPYRUS) REVEALS HIGH VARIABILITY IN CLOT KINETICS.

Megachiroptera is a mammalian suborder that includes old world fruit bats. Common clinical problems among captive Megachiroptera, such as liver disease (e.g., iron storage disease), kidney disease (e.g., protein-losing nephropathy), and heart disease (e.g., dilated cardiomyopathy), carry elevated risk for hemostatic derangements. The assessment of viscoelastic coagulation assays, however, has not yet been reported in bats. The main objective of the study was to describe viscoelastography data using the Viscoelastic Coagulation Monitor (VCM) Vet in captive large flying foxes (Pteropus vampyrus) (n = 20) and variable flying foxes (Pteropus hypomelanus) (n = 10). Additional objectives were to compare viscoelastic and clotting parameters (1) between healthy P. vampyrus and P. hypomelanus bats and (2) between untreated bats and those treated with meloxicam or aspirin, and (3) to examine relationships between activated partial thromboplastin time (aPTT) and potentially homologous viscoelastic parameters clotting time (CT) and clot formation time (CFT). The results showed marked variability among clinically normal bats. The intrinsic pathway, as measured by aPTT, had prolonged times compared with most terrestrial mammals, but similar times to birds, marine mammals, and sea turtles. A search of P. vampyrus genome found stop codons present in two exons of the factor XI gene; alterations in factor XI expression would be expected to alter intrinsic coagulation. Because of the high variability, no statistically significant findings were noted in the secondary objectives. Correlation between aPTT and CT or CFT was not strong (rs = 0.406 or 0.192, respectively). The results from this study suggest that clot kinetics vary widely among Megachiroptera when using the VCM Vet with untreated blood. A prolonged intrinsic coagulation pathway, as has been found in other megachiropteran species, and activation of the extrinsic coagulation pathway during venipuncture may be responsible for the inconsistent results.

Virtual surgical planning and mirrored, 3-dimensionally printed guides for corrective clavicle osteotomies in clavicle malunions and nonunions.

BACKGROUND: The objective of this study was to retrospectively review clinical and radiographic outcomes of patients who underwent corrective osteotomies for clavicle malunion and internal fixation for nonunion using a combination of virtual surgical planning, patient-specific 3-dimensional (3D)-printed clavicles, and 3D-printed cutting guides manufactured at the point of care. METHODS: Between 2015 and 2021, 18 patients underwent corrective osteotomy for a clavicle malunion (7 shoulders) or internal fixation for a clavicle nonunion (11 shoulders). There were 11 male and 7 female individuals with an average patient age of 43.9 (range 19-76) years. All patients underwent computed tomography evaluation of both clavicles. The DICOM files were manually segmented, virtual surgical planning was performed selectively using commercially available software, and a mirrored version of the normal clavicle was 3D printed along with a 3D-printed replica of the affected clavicle. Three-dimensionally printed mirrored clavicles were used in all cases to ensure adequate restoration of the shape and length of the clavicle and to precontour fixation plates. Virtual surgical planning and 3D-printed cutting guides for osteotomy were used in 4 of 18 (22%) patients. Either cancellous or structural intercalary bone grafting was used in 15 of 18 (83%) cases. Patients were contacted postoperatively to determine clinical outcome scores. Preoperative, early postoperative, and late postoperative radiographs were reviewed to assess for union and complications. The average follow-up time was 24.9 months. RESULTS: Radiographic evaluation at the most recent follow-up demonstrated adequate restoration of length and successful union for all shoulders. There were no complications or reoperations. Postoperative patient-reported outcomes could be obtained in 16 of 18 (88.9%) patients. At the most recent follow-up, the mean visual analog scale for pain was 2.38 points (range, 1-7), the mean shoulder American Shoulder and Elbow Surgeons score was 73.2 points (range, 25-100), and the mean Patient-Reported Outcome Measurement Information System Upper Extremity score was 26 points (range, 7-35). All (100%) the patients were satisfied with their outcome (9 very satisfied, 7 satisfied), and their mean subjective shoulder value was 73% (range, 10%-100%). However, 2 patients complained of hardware-related symptoms, and 1 patient had return of preoperative symptoms after an interim 2 years of pain relief. CONCLUSION: The use of mirrored 3D-printed clavicles combined with virtual surgical planning and patient-specific 3D guides provides a reliable technique for restoring native anatomy when performing corrective osteotomies for clavicle malunion or internal fixation for clavicle nonunion, with a high rate of satisfactory clinical and radiographic outcomes.

Pharmacokinetics and pharmacodynamics of intramuscular alfaxalone in central bearded dragons (Pogona vitticeps): effect of injection site.

OBJECTIVE: To evaluate the pharmacodynamic effects and pharmacokinetics of a single intramuscular (IM) injection of alfaxalone in central bearded dragons (Pogona vitticeps) when injected at a cranial versus a caudal site. STUDY DESIGN: Prospective, masked, randomized crossover study. ANIMALS: A total of 13 healthy bearded dragons weighing 0.48 ± 0.1 kg. METHODS: Alfaxalone (10 mg kg-1) was administered IM to 13 bearded dragons in the triceps muscle (cranial treatment) or the quadriceps muscle (caudal treatment) separated by 4 weeks. Pharmacodynamic variables included movement score, muscle tone score and righting reflex. Blood was obtained from the caudal tail vein using a sparse sampling methodology. Plasma alfaxalone concentrations were determined using liquid chromatography-mass spectrometry, and pharmacokinetic analysis was performed using nonlinear mixed-effects modeling. Differences in variables between injection sites were analyzed using a nonparametric Wilcoxon signed-rank test for paired data with significance set at p ≤ 0.05. RESULTS: Time to loss of righting reflex score was not different, median (interquartile range), between cranial and caudal treatments [8 (5-11) and 8 (4-12) minutes, respectively, p = 0.72]. Time to recovery of righting reflex was also not different between cranial and caudal treatments [80 (44-112) and 64 (56-104) minutes, respectively, p = 0.75]. Plasma alfaxalone concentrations were not significantly different between treatments. The population estimate (95% confidence intervals) for volume of distribution per fraction absorbed was 1.0 (0.79-1.20) L kg-1, clearance per fraction absorbed was 9.6 (7.6-11.6) mL minute-1 kg-1, absorption rate constant was 2.3 (1.9-2.8) minute-1 and elimination half-life was 71.9 (52.7-91.1) minutes. CONCLUSIONS AND CLINICAL RELEVANCE: Regardless of the injection site, IM alfaxalone (10 mg kg-1) produced reliable chemical restraint in central bearded dragons, appropriate for nonpainful diagnostic procedures or anesthetic premedication.

DETERMINATION OF ECHOCARDIOGRAPHIC TECHNIQUES FOR CLINICAL ASSESSMENT OF GALAPAGOS (CHELONOIDIS NIGRA COMPLEX) AND ALDABRA (ALDABRACHELYS GIGANTEA) TORTOISES.

The first objective of this study was to establish clinically relevant techniques for cardiac echocardiography in nonanesthetized Galapagos (Chelonoidis nigra complex) and Aldabra (Aldabrachelys gigantea) tortoises. A second objective was to establish guidelines for determining normal echocardiographic anatomy and function in both species. Select echocardiographic reference values were defined for 17 healthy Galapagos tortoises and 27 healthy Aldabra tortoises. Tortoises were either placed in ventral recumbency on an elevated surface or allowed to stand in a natural position by using food distraction. An ultrasound probe was applied in the left or right cervicobrachial window and was positioned in two long axis views to evaluate the three chambers of the heart and the associated great vessels, the presence of pericardial effusion, the atrioventricular inflow velocities, and pulmonic and aortic outflow velocities. The heart rate was 28 ± 12 (median ± SD) bpm, and the ejection fraction was 60.5 ± 10%. Thirty-four of 44 tortoises had identifiable physiologic pericardial effusion. All tortoises were successfully imaged using the techniques described, with consistent identification of cardiac structure and assessment of function. This study provides echocardiographic reference intervals for the clinical evaluation of suspected cardiac disease in captive-managed Galapagos and Aldabra tortoises.

Intralipid Emulsion Therapy for the Treatment of Suspected Toxicity in 2 Avian Species.

Intravenous lipid emulsion (ILE) therapy has shown promise as a treatment option for a variety of lipophilic toxins. Two birds presented for suspected ingestion of a toxic substance. A blue-and-gold macaw (Ara ararauna) presented after chewing a block of bromethalin rodenticide without overt clinical signs at the time of presentation. Additionally, a free-ranging bald eagle (Haliaeetus leucocephalus) was found weak and depressed near a municipal landfill after presumptive ingestion of pentobarbital. Both birds were treated with ILE therapy for potential intoxication without any adverse events. The macaw was clinically normal after 3 days of hospitalization and at a 1-week reevaluation. The eagle was transferred to a rehabilitation center after markedly improved mentation and strength and was released 7 days later. Clinicians should consider ILE therapy for the treatment of lipophilic toxicities; however, monitoring is recommended for persistent lipemia and other adverse effects that have been reported in the veterinary literature.

Accuracy and Precision of the Computed Tomographic Angiography Perforator Localization Technique for Virtual Surgical Planning of Composite Osteocutaneous Fibular Free Flaps in Head and Neck Reconstruction.

BACKGROUND: Virtual surgical planning (VSP), computer aided design/computer aided modeling, and 3-dimensional printing technology have been shown to improve surgical accuracy and efficiency in head and neck reconstruction. However, persisting criticism of the technology is that it does not adequately address the soft tissue-related aspects of reconstructive surgery. Prior publication on the computed tomographic angiography (CTA) perforator localization technique has demonstrated how soft tissue planning can be incorporated directly into existing VSP workflows. PURPOSE: The aim of this study is to prospectively assess the accuracy, precision, negative predictive value (NPV), and positive predictive value (PPV) of the CTA perforator localization technique for VSP of osteocutaneous fibular free flaps. MATERIALS AND METHODS: A prospective observational study in a consecutive cohort of subjects undergoing VSP of osteocutaneous fibular free flaps at Mayo Clinic between 2018 and 2020 was completed. All cutaneous perforators from the peroneal system of the selected donor leg were identified preoperatively through a previously reported CTA tracing method and registered into the VSP. Perforators were classified as primary or secondary based on whether the perforators were targeted for use in the final reconstructive plan. Perforator measurements obtained from the VSP were cross-referenced with intraoperatively obtained measurements of actual perforator locations to calculate accuracy, precision, NPV, PPV, sensitivity, and specificity of the CTA localization technique. RESULTS: Sixty consecutive subjects were enrolled in the study. A total of 141 perforators were identified preoperatively on CTA and 145 perforators were identified on operative exposure. One perforator identified on preoperative CTA was not identified on surgical exposure (false positive perforator). Six perforators were identified on operative exposure alone without recognition on preoperative CTA (false negative perforators). The accuracy of CTA perforator identification was 96.52%. Median precision of perforator localization was 0.3 cm (standard deviation 0.40) between CTA and operatively identified locations. PPV of the technique was 99.29% and NPV was 90.00%. CONCLUSION: The CTA localization technique for identifying and incorporating cutaneous perforator locations into VSP of osteocutaneous fibular free flaps is a reliable, accurate, and precise technique to employ in the modern paradigm of guided surgery for head and neck reconstruction.

PULMONARY AND COELOMIC MYCOSES DUE TO METARHIZIUM AND BEAUVERIA SPECIES IN REPTILES.

This report documents cases of fatal pulmonary mycosis caused by entomopathogenic fungi in the genera Metarhizium and Beauveria (Order Hypocreales) in a loggerhead sea turtle (Caretta caretta), a Chinese alligator (Alligator sinensis), two gopher tortoises (Gopherus polyphemus), a Cuvier's dwarf caiman (Paleosuchus palpebrosus), a false gharial (Tomistoma schlegelii), a green sea turtle (Chelonia mydas), and a Kemp's ridley sea turtle (Lepidochelys kempii), and a case of granulomatous coelomitis in a hawksbill sea turtle (Eretmochelys imbricata). Fungi identified in these cases included Beauveria bassiana, Beauveria brongniartii, Metarhizium anisopliae, Metarhizium robertsii, and one case of infection by a novel Metarhizium species. The animals were either housed at zoos or brought into rehabilitation from the wild. Although the majority of animals had comorbidities, the fungal infections were believed to be the primary cause of death. Fungal susceptibility testing was performed on two Beauveria spp. isolates, and revealed lower minimum inhibitory concentrations for itraconazole and voriconazole when compared to terbinafine and fluconazole. This case series demonstrates that a variety of reptile species from different orders are vulnerable to infection with Metarhizium, and multiple species of sea turtle are susceptible to infection with Beauveria.

Survival after Minimally Invasive Radical Hysterectomy for Early-Stage Cervical Cancer.

BACKGROUND: Minimally invasive surgery was adopted as an alternative to laparotomy (open surgery) for radical hysterectomy in patients with early-stage cervical cancer before high-quality evidence regarding its effect on survival was available. We sought to determine the effect of minimally invasive surgery on all-cause mortality among women undergoing radical hysterectomy for cervical cancer. METHODS: We performed a cohort study involving women who underwent radical hysterectomy for stage IA2 or IB1 cervical cancer during the 2010-2013 period at Commission on Cancer-accredited hospitals in the United States. The study used inverse probability of treatment propensity-score weighting. We also conducted an interrupted time-series analysis involving women who underwent radical hysterectomy for cervical cancer during the 2000-2010 period, using the Surveillance, Epidemiology, and End Results program database. RESULTS: In the primary analysis, 1225 of 2461 women (49.8%) underwent minimally invasive surgery. Women treated with minimally invasive surgery were more often white, privately insured, and from ZIP Codes with higher socioeconomic status, had smaller, lower-grade tumors, and were more likely to have received a diagnosis later in the study period than women who underwent open surgery. Over a median follow-up of 45 months, the 4-year mortality was 9.1% among women who underwent minimally invasive surgery and 5.3% among those who underwent open surgery (hazard ratio, 1.65; 95% confidence interval [CI], 1.22 to 2.22; P=0.002 by the log-rank test). Before the adoption of minimally invasive radical hysterectomy (i.e., in the 2000-2006 period), the 4-year relative survival rate among women who underwent radical hysterectomy for cervical cancer remained stable (annual percentage change, 0.3%; 95% CI, -0.1 to 0.6). The adoption of minimally invasive surgery coincided with a decline in the 4-year relative survival rate of 0.8% (95% CI, 0.3 to 1.4) per year after 2006 (P=0.01 for change of trend). CONCLUSIONS: In an epidemiologic study, minimally invasive radical hysterectomy was associated with shorter overall survival than open surgery among women with stage IA2 or IB1 cervical carcinoma.

College Student Perspectives of Telemental Health: a Review of the Recent Literature.

PURPOSE OF REVIEW: We review the recent literature regarding college student experiences with and attitudes toward telemental health (TMH). We examine their perspectives of the advantages and drawbacks to this form of mental healthcare and their willingness to engage in TMH. RECENT FINDINGS: College students view TMH as convenient, accessible, easy to use, and helpful. TMH helps to overcome the barrier of stigma associated with seeking mental health treatment. Despite positive reviews, many students find a lack of customization or connection to the provider to be drawbacks to some forms of TMH. Willingness to engage in TMH varies based on prior experience with mental health treatment, ethnicity, and severity of symptoms. The recent literature highlights the potential for TMH to play a key role in mental health services for college students. It also highlights some of its shortcomings, which are indicative of the continued need for in-person services. Future studies should continue to track college student perspectives toward and utilization of TMH.

Standardized Surgical Video Curriculum for Teaching Residents Principles of Abdominal Hysterectomy.

OBJECTIVES: To evaluate whether an institutionally created video-based educational module will improve obstetrics and gynecology residents' understanding of surgical anatomy and principles for performing abdominal hysterectomy. Secondary aims included evaluating the trainees' confidence levels and perceptions before and after the educational experience and ultimately implementing the module into the program curriculum, if successful. METHODS: In this prospective study, postgraduate obstetrics and gynecology resident physicians (n = 27) at the McGaw Medical Center of Northwestern University were assigned to watch an institutionally created video-based educational module on abdominal hysterectomy before the start of their gynecologic oncology rotation. A knowledge assessment and a postmodule survey were given to participants immediately following the module and repeated at the end of the 4-week rotation. RESULTS: Participants reported a median rating of 4 (n = 21, interquartile range 4-4) on a 5-point Likert scale when asked to rate the quality of the module. The module also was rated as equally effective both immediately after watching the module and after completing their gynecologic oncology rotation (median 4, interquartile range 3-4 at both times; p = 0.299, Wilcoxon signed rank test). Overall trends revealed that the video module had a greater impact on knowledge of surgical anatomy than on self-reported surgical skills and that postgraduate year 2 and postgraduate year 3 residents benefited more from the intervention. CONCLUSIONS: A video module can be a high-quality and effective educational tool for teaching the surgical principles, anatomy, and steps to perform abdominal hysterectomy to obstetrics and gynecology residents.

Retrospective analysis of ocular disease in a population of captive pteropodid bats, 2003-2020.

OBJECTIVE: To perform retrospective analysis of captive pteropodid bats presented to the University of Florida for ocular or adnexal disease from 2003-2020. ANIMALS STUDIED: Twenty-four individuals from seven species were included. PROCEDURES: Records were analyzed for disease process, methods of treatment, and surgical techniques and complications. RESULTS: The most frequently reported abnormality was corneal disease (79%), followed by cataracts (54%), and uveitis (42%). Corneal disease was primarily attributed to either trauma or exposure keratitis secondary to buphthalmia. The majority of uveitis appeared to be lens-induced. Five cases (21%) of glaucoma were reported, all of which accompanied lens luxation. Of the seven enucleations performed, six had post-operative complications (85.7%), including swelling at the surgical site, seroma formation, and bacterial infection. There was no significant relationship between age and trauma, age and cataract formation, sex and trauma, or species and cataract formation. CONCLUSIONS: The most common underlying cause of ocular pathology in these cases was trauma. While the bats tolerated topical and systemic treatment well, individual temperament must be taken into account when developing treatment plans, and prevention of injury is the most effective management strategy.

THE USE OF INTRADERMAL ALLERGY TESTING FOR ALLERGIC DERMATITIS IN PTEROPID BATS AND TREATMENT WITH ALLERGEN SPECIFIC IMMUNOTHERAPY: A CASE SERIES.

This case series describes the diagnosis of allergic dermatitis and management with allergen-specific immunotherapy (ASIT) based on intradermal allergy testing (IDAT) and adjunctive medical therapy in six pteropid bats; five large flying foxes (Pteropus vampyrus); and one variable flying fox (Pteropus hypomelanus). The cases ranged from 2 to 15 yr of age at the time of presentation. Clinical signs varied between individuals and included moist ulcerative cutaneous lesions in nonhaired skin, blepharoconjunctivitis, alopecia, and pruritus. All bats underwent IDAT under general anesthesia, and reactive allergens included a mixture of grasses, trees, weeds, and biting insects. Three of the six cases (50%) had reformulation of the ASIT before control of clinical signs was seen, and two bats were treated with the addition of oclacitinib (Apoquel). Severe adverse effects were not identified; however, one bat had self-limiting swelling at the immunotherapy injection site. All six cases showed improvement of clinical signs and perceived comfort level, including in subsequent allergy seasons.

Novel Geometry of an Extended Length Chimeric Scapular Free Flap for Hemimandibular Reconstruction: Nuances of the Technique Streamlined by In-House Virtual Surgical Planning and 3D Printing for a Severely Vessel-Depleted Neck.

Subscapular-based flaps have historically maintained an unparalleled ability to provide a multitude of bone and soft tissue components based on a single vascular pedicle. However, these flaps are often not thought of as an ideal choice for composite defects requiring extended lengths of bone for reconstruction. The ability to harvest long segments of bone and reliably perform multiple contouring osteotomies is fundamental to long-span composite mandibular reconstruction, and microvascular surgeons are often met with significant reconstructive challenges when fibular free flaps cannot be used owing to variant vascular anatomy or occlusive atherosclerotic disease in these specific clinical scenarios. This challenge is further compounded by treatment-related vessel depletion in the neck, which reduces the availability of suitable recipient vessels in close proximity to the reconstruction. We present a case in which all of the aforementioned challenges presented in a single individual, who concomitantly required hemimandibular reconstruction with treatment related vessel depletion in the neck and unsuitable bilateral vascular anatomy in the legs precluding the use of a fibular free flap. This case demonstrates a previously unreported flap component geometry for hemimandibular reconstruction using an extended-length chimeric scapular free flap with scapular tip, lateral scapular border, and parascapular fasciocutaneous skin paddle components.

Orchard grass allergy in an African spur-thighed tortoise (Centrochelys sulcata) confirmed via intradermal allergen testing and provocation testing.

The humoral immune system of reptiles is not well-studied. To the best of the authors' knowledge, this case report describes the first case of a type I allergic conjunctivitis associated with orchard grass in an African spur-thighed tortoise (Centrochelys sulcata) supported by intradermal allergen testing and provocative testing. Further studies are needed to better characterize allergic reactions in reptiles.

RENAL NEOPLASIA FROM A SINGLE POPULATION OF PTEROPODID BATS.

Neoplastic diseases have rarely been reported in the family Pteropodidae, and primary malignant renal neoplasms are generally uncommon across animal species. This case series describes four cases of primary renal neoplasia: three renal cell carcinomas and one nephroblastoma in three species of pteropodid bats, specifically large flying foxes (Pteropus vampyrus, n = 2), straw-colored fruit bat (Eidolon helvum, n = 1), and a little golden-mantled flying fox (Pteropus pumilus, n = 1). Two of the cases were diagnosed antemortem using ultrasonography, computed tomography, and cytology; and one of these bats with a renal cell carcinoma was treated successfully with a unilateral nephrectomy. The remaining two cases were diagnosed at necropsy.

Benign hysterectomy performed by gynecologic oncologists: Is selection bias altering our ability to measure surgical quality?

OBJECTIVE: To compare the characteristics of women undergoing hysterectomy for benign disease with either a benign gynecologist or a gynecologic oncologist and to assess for differences in complication rates with and without risk adjustment. METHODS: Patients undergoing benign hysterectomy recorded in the National Surgical Quality Improvement Program (NSQIP) targeted hysterectomy file in 2015 were identified. The primary outcome was any postoperative complication. Stratified analysis was performed by route of surgery. Bivariable tests and modified Poisson regression were used to adjust for confounding by procedure type and patient characteristics. RESULTS: We identified 17,639 patients who underwent hysterectomy for benign pathology, primary surgeon was a benign gynecologist (82%) or gynecologic oncologist (18%). Patients who underwent surgery with gynecologic oncologists were older (51yo v 46yo), had a higher mean BMI (32 v 30), and a higher prevalence of prior abdominal surgery (29% v 25%, p < 0.001), diabetes (10.6% v 7.0%), hypertension (34% v 25%) and higher ASA and Charlson comorbidity scores (p < 0.001, for all). For laparoscopy, surgery with a gynecologic oncologist was associated with a decreased risk of complication (RR 0.80, 95% CI 0.66-0.98). For laparotomy, surgery with a gynecologic oncologist was associated with an increased risk of complication (RR 1.18 95% CI 1.01-1.38), however, this was no longer the case with risk adjustment (aRR 0.90, 95% CI 0.76-1.07). CONCLUSIONS: Patients operated on by gynecologic oncologists have a higher prevalence of risk factors for complication compared to those operated on by benign gynecologists even with a benign indication for surgery. Quality measurement should account for this selection bias.

Prognosis and treatment of positive peritoneal cytology in early endometrial cancer: matched cohort analyses from the National Cancer Database.

BACKGROUND: While positive peritoneal cytology is no longer included among the endometrial cancer staging criteria, Federation International de Gynecologie et Obstetrique recommends continued collection of pelvic washings for cytology to produce additional data that may be used to determine the significance of positive cytology for prognosis and treatment of endometrial cancer. OBJECTIVES: The objectives of the study was to validate that positive cytology is a predictor of decreased survival in early endometrial cancer and to test whether adjuvant chemotherapy for positive cytology is associated with increased survival. STUDY DESIGN: We performed an observational retrospective cohort analysis of the 2010-2013 National Cancer Database including women with cytology status and Federation International de Gynecologie et Obstetrique stage IA-II endometrial cancer. Overall cohort and matched cohort survival analyses were performed with and without imputation of missing data. We also performed survival analyses of women with positive cytology grouped by chemotherapy exposure. Multivariable Cox proportional-hazards regressions were performed to adjust for possible confounders. A variety of sensitivity analyses, including robustness of results to possible unmeasured confounding, were reported. RESULTS: A total of 16,851 women including 953 with positive cytology were included. Four-year overall survival was 79.5% (range, 76.2-83.0%) for women with stage I/II with positive cytology vs 92.2% (range, 91.5-92.9%), 83.3% (range, 81.6-84.9%), and 86.8% (range, 85.1-88.5%) for stage IA, IB, and II with negative cytology, respectively (P ≤ .001). Positive cytology was associated with decreased survival (hazard ratio [95% confidence interval], 1.85 [range, 1.54-2.21], P < .001). For women with Federation International de Gynecologie et Obstetrique grade 1/2 endometrioid adenocarcinoma, the hazard of death associated with positive cytology was similar (hazard ratio [95% confidence interval], 1.85 [1.28-2.67], P < .001). Use of adjuvant chemotherapy by women with positive cytology was associated with increased survival (hazard ratio [95% confidence interval], 0.62 [0.40-0.95], P = .03). CONCLUSION: Positive peritoneal cytology was associated with decreased overall survival of women with Federation International de Gynecologie et Obstetrique stage I/II endometrial cancer, including low-grade endometrioid endometrial cancer. Treatment of women with stage I/II endometrial cancer and positive cytology with adjuvant chemotherapy was associated with increased survival.

Discussing sarcoma risks during informed consent for nonhysterectomy management of fibroids: an unmet need.

There is no reliable way to distinguish symptomatic uterine fibroids from sarcoma without a surgical specimen. Many women with a uterine sarcoma are initially managed without hysterectomy under a presumed fibroid diagnosis, without understanding sarcoma risks. Currently many alternatives to hysterectomy, including medical and procedural interventions, for treatment of fibroids are promoted. The sarcoma incidence among women with presumed fibroids is 0.29% (1/340) to 0.05% (1/2000). Nonmetastatic leiomyosarcoma has a 63% 5-year survival rate whereas metastatic leiomyosarcoma has a 14% 5-year survival rate. In uterine sarcoma, we often cannot identify who has sarcoma before making a potentially cure-denying decision by delaying surgery. Therefore, women electing an alternative to hysterectomy for fibroids should undergo an informed consent process that specifically includes discussion of uterine sarcoma incidence and mortality. Alternatives to hysterectomy for presumed fibroids remain preferable treatment options for many women with symptomatic fibroids, so long as underlying sarcoma risks are adequately discussed. The challenge for obstetrician- gynecologists then is how to provide better informed consent and maintain the primacy of patient autonomy over our concern to "First, do no harm." Major threats to patient's autonomy are faced in the sarcoma risk discussion. How we should present sarcoma risk information to avoid being dismissive of sarcoma or frightening women toward hysterectomy is unstudied. Research is needed to determine how to provide sarcoma risk information with less bias during informed consent.

Comparison of Uninjured and Concussed Adolecent Athletes on the Concussion Balance Test (COBALT).

BACKGROUND AND PURPOSE: Dizziness and balance problems are common symptoms following sports-related concussion (SRC). Most sports require high-level balance skills that integrate the sensory inputs used for balance. Thus, a comprehensive assessment of postural control following SRC is recommended as an integral part of evaluation and management of the injury. The purpose of this exploratory study was to examine performance differences between uninjured and concussed athletes on the Concussion Balance Test (COBALT), as well as complete preliminary analyses of criterion-related validity and reliability of COBALT. METHODS: COBALT is an 8 condition test developed for both preseason and postinjury assessment using force plate technology to measure sway velocity under dynamic postural conditions that challenge the vestibular system. Retrospective COBALT data obtained through chart review for 132 uninjured athletes and 106 concussed age-matched athletes were compared. RESULTS: All uninjured athletes were able to complete the assessment, compared with only 55% of concussed athletes. Concussed athletes committed significantly more errors than uninjured athletes. Sway velocity for concussed athletes was higher (worse) than that for uninjured athletes on 2 conditions in COBALT. DISCUSSION AND CONCLUSIONS: By examining an athlete's ability to complete the protocol, error rate, and sway velocity on COBALT postinjury, the clinician can identify balance function impairment, which may help the medical team develop a more targeted treatment plan, and provide objective input regarding recovery of balance function following SRC.Video Abstract available for more insights from the authors (see Supplemental Digital Content 1, available at: http://links.lww.com/JNPT/A204).
