Background Metacarpal fractures are common in football players and lead to time away from competition, but current operative treatment data is limited. The purpose of this study was to examine demographics and outcomes of football players who underwent operative fixation for metacarpal fractures. Methods Retrospective review from 2009 to 2012 of any football player surgically treated at one institution for a metacarpal fracture. Charts were reviewed for player position, level of competition, mechanism of injury, return to play, postoperative bracing, and re-fracture event. Current information was obtained via phone interviews with the patient and their athletic trainers. Fractures were classified by radiographic analysis. Results Twenty injuries in ten high school players, nine college players, and one recreational player were identified. The most common injured position was wide receiver (six cases) followed by defensive back (five cases). Most injuries occurred through player-to-player contact (12 cases). The long finger (11 cases) was most commonly involved metacarpal. Two players had multiple metacarpal fractures. The most common location was mid-diaphyseal (15 cases). The mean return to play for all in-season athletes was 6.3 days (range 1–21). Protective splints were used for an average of 21 days (range 14–36). All athletes returned to their preinjury level of play without recurrence of fracture or wound complication. Conclusion Football players who required surgical fixation of a metacarpal fracture demonstrated an efficient return to play, including in-season players with use of protective bracing.

AbstractBuriti oil contains nutrients such as essential fatty acids and vitamins, which are directly involved with neonates' development. However, the refining process of this oil can change its nutrient profile. This study investigated the effects of maternal consumption of Buriti oil (crude or refined), on reflex and somatic development and retinol levels in neonatal rats. Thirty‐six Wistar male neonate rats born from mothers who consumed diet with 7% lipids during gestation and lactation were used. Rats were randomized into three groups: rats receiving diet added of soybean oil (control‐CG), crude Buriti oil (CB) and refined Buriti oil (RB). Offspring weight, tail length, reflex ontogeny and somatic maturation were assessed during lactation. At the end of the experiment, serum and liver retinol concentrations were measured. Animals from CB and RB groups showed delayed onset of palm grasp, righting reflex and cliff avoidance reflexes compared to the control group (CG). However, animals from RB group showed anticipation of auditory startle compared to those from BC group. Regarding somatic maturation indicators, animals from RB group showed delayed eye opening and eruption of superior and inferior incisors in relation to control and anticipation in the auditory conduit opening in relation to CB group. Rats from CB and RB groups showed higher serum and liver vitamin A contents. Buriti oil delays physical parameters and reflex maturation and increases serum and liver retinol deposition among neonatal rats.

Abstract
Chronic refractory venous hypertension is a common complication following repeated central venous cannulation performed as a temporary vascular access for dialysis in patients with chronic renal failure. The symptoms of venous hypertension may diverge from being asymptomatic to severe edema, ulceration, headaches, bloating, and blackouts, especially if the patient has a surgical arteriovenous fistula for dialysis in any of his upper limbs. Treatment options for such patients are mainly directed toward endovascular management via balloon angioplasty and possibly stenting of the stenosed vein. Resistant lesions or cases with total venous occlusion coerce surgeons to consider surgical bypass. We present a case of a 43-year-old patient with history of renal impairment and repeated bilateral central venous cannulation for dialysis. The patient experienced superior vena cava syndrome with bilateral total occlusion of the internal jugular veins and both subclavian veins (with an occluded previously inserted stent) along with the superior vena cava. An extra-anatomical bypass was done from the left internal jugular vein to the left external iliac vein using a synthetic silver Dacron ringed graft. The procedure was successful and resulted in relief of the patient's symptoms and a dramatic improvement of the patient's quality of life. Superior vena cava syndrome represents 1 of the most challenging complications for patients with chronic renal impairment and repeated central venous cannulation. The endovascular approach is currently gaining popularity as the first line of treatment for such patients. However, surgical management is sometimes the only available option when the endovascular approach is not technically feasible. Our case, along with others, shows that an extra-anatomical synthetic graft bypass can be a reliable, less invasive option for the management of superior vena cava syndrome once surgical intervention is inevitable.

Abstract
Introduction: Placement of totally implanted venous access devices, or port systems, in the upper arm is becoming a common practice in interventional radiology. To gain a better understanding of the literature in this area, we performed a search for and analysis of previous publications related to upper arm implantation of these devices by members of interventional radiology departments.
Methods: A review of the literature pertaining to upper arm port systems implanted in human beings by members of interventional radiology departments was performed, assessing publications between the years 1992 and 2014. Only English-language publications were assessed.
Results: Eighteen publications met selection criteria during the time frame reviewed. None of the studies used a prospective, randomized design; rather, all studies consisted of case–cohort descriptions of outcomes for a single device or for multiple devices. Analysis of the available literature for interventional radiology-inserted arm ports was performed. The technical success rate ranged between 93.7% and 100%, with an average of 98.9%.
Conclusions: The high technical success rate of arm port implantation and the elimination of the potential for pneumothorax, hemothorax, catheter pinch-off syndrome, and subclavian and carotid artery injury are strengths of the arm implantation strategy. There was wide variation in the rates of complications detected, in addition to inconsistent study design and study implementation strategies.

AbstractBackgroundHandball is one of the most challenging sports for the knee joint. Persistent biomechanical and jumping capacity alterations can be observed in athletes with an anterior cruciate ligament (ACL) injury. Commonly identified jumping biomechanical alterations have been described by the use of laboratory technologies. However, portable and easy‐to‐handle technologies that enable an evaluation of jumping biomechanics at the training field are lacking.ObjectiveTo analyze unilateral/bilateral acceleration and orientation jumping performance differences among elite male handball athletes with or without previous ACL reconstruction via a single inertial sensor unit device.DesignCase control descriptive study.SettingAt the athletes' usual training court.ParticipantsTwenty‐two elite male (6 ACL‐reconstructed and 16 uninjured control players) handball players were evaluated.MethodsThe participants performed a vertical jump test battery that included a 50‐cm vertical bilateral drop jump, a 20‐cm vertical unilateral drop jump, and vertical unilateral countermovement jump maneuvers.Main outcome measurementsPeak 3‐dimensional (X, Y, Z) acceleration (m·s−2), jump phase duration and 3‐dimensional orientation values (°) were obtained from the inertial sensor unit device. Two‐tailed t‐tests and a one‐way analysis of variance were performed to compare means. The P value cut‐off for significance was set at P < .05.ResultsThe ACL‐reconstructed male athletes did not show any significant (P < .05) residual jumping biomechanical deficits regarding the measured variables compared with players who had not suffered this knee injury. A dominance effect was observed among non‐ACL reconstructed controls but not among their ACL‐reconstructed counterparts (P < .05).ConclusionsElite male handball athletes with previous ACL reconstruction demonstrated a jumping biomechanical profile similar to control players, including similar jumping performance values in both bilateral and unilateral jumping maneuvers, several years after ACL reconstruction. These findings are in agreement with previous research showing full functional restoration of abilities in top‐level male athletes after ACL reconstruction, rehabilitation and subsequent return to sports at the previous level.

AbstractObjectivesTo describe and validate a sonographically guided (SG) semimembranosus (SM) bursa injection technique in an unembalmed cadaveric model.DesignProspective, cadaveric laboratory investigation.SettingAcademic institution procedural skills laboratory.SubjectsTen unembalmed cadaveric thigh‐knee‐ankle‐foot specimens from 4 male and 6 female donors ages 55‐92 years (mean 76.2 years) with body mass indices of 15.4‐31.8 kg/m2 (mean 21.9 kg/m2).MethodsA single, experienced operator completed SG SM bursa injections in 10 unembalmed cadaveric knees using 3 mL of diluted colored latex. At a minimum of 2 days after the injection, co‐investigators dissected the specimens to assess the distribution of latex with respect to the SM bursa.Main OutcomeInjections were graded for accuracy as follows: accurate (all latex contained within the SM bursa), accurate with overflow (latex within the SM bursa and extending into regions other than the needle track), or inaccurate (no latex within the SM bursa).ResultsAll 10 injections (100%) accurately placed latex within the SM bursa and resulted in proximal spread to at least the level of the knee joint. Eight of 10 injections (80%) demonstrated minimal (<1 mL) extrabursal flow without extension into the intra‐articular space. No neurovascular injury occurred in any specimen.ConclusionsSG SM injections are feasible and accurate and may be considered for diagnostic and therapeutic injections in patients with suspected distal SM disorders. Injection volumes less than 3 mL should be considered to reduce extrabursal spread as clinically indicated.

AbstractAdenoid cystic carcinoma (ACC) of the salivary gland often metastasizes to the lungs. It has previously been reported that the combination chemotherapy of weekly paclitaxel plus cetuximab is effective for the treatment of lung metastasis from ACC of the salivary gland. Here, we report a case in which a regimen of this combination therapy provided an antitumor treatment for lung metastatic ACC arising from the minor salivary gland of the hard palate.

ABSTRACTObjectivesBy the end of residency training, pediatric emergency medicine (PEM) residents are expected to have developed the confidence and abilities required to manage acutely ill children. Acquisition of competence requires exposure and/or supplemental formal education for critical and noncritical medical clinical presentations. Simulation can provide experiential learning and can improve trainees’ knowledge, skills, and attitudes. The primary objective of this project was to identify the content for a simulation-based national curriculum for PEM training.MethodsWe recruited participants for the Delphi study by contacting current PEM program directors and immediate past program directors as well as simulation experts at all of the Canadian PEM fellowship sites. We determined the appropriate core content for the Delphi study by combining the PEM core content requirements of the Royal College of Physicians and Surgeons of Canada (RCPSC) and the American Board of Pediatrics (ABP). Using the Delphi method, we achieved consensus amongst the national group of PEM and simulation experts. The participants completed a three-round Delphi (using a four-point Likert scale).ResultsResponse rates for the Delphi were 85% for the first round and 77% for second and third rounds. From the initial 224 topics, 53 were eliminated (scored <2). Eighty-five topics scored between 2 and 3, and 87 scored between 3 and 4. The 48 topics, which were scored between 3.5 and 4.0, were labeled as “key curriculum topics.”ConclusionWe have iteratively identified a consensus for the content of a national simulation-based curriculum.

Published: May 2015

AbstractObjectivesThis study aimed to ascertain the association between self-reported pain intensity and vital signs in both emergency department (ED) patients and a subgroup of patients with diagnosed conditions known to produce significant pain.MethodsWe performed a retrospective analysis of real-time, archived data from an electronic medical record system at an urban teaching hospital and regional community hospital. We included consecutive ED patients ≥16 years old who had a self-reported pain intensity ≥1 as measured during triage, from March 2005 to December 2012. The primary outcome was vital signs for self-reported pain intensity levels (mild, moderate, severe) on an 11-point verbal numerical scale. Changes in pain intensity levels were also compared to variations in vital signs. Both analyses were repeated on a subgroup of patients with diagnosed conditions recognized to produce significant pain: fracture, dislocation, or renal colic.ResultsWe included 153,567 patients (mean age of 48.4±19.3 years; 55.5% women) triaged with pain (median intensity of 7/10±3). Of these, 8.9% of patients had diagnosed conditions recognized to produce significant pain. From the total sample, the difference between mild and severe pain categories was 2.7 beats/minutes (95% CI: 2.4−3.0) for heart rate and 0.13 mm Hg (95% CI: -0.26−0.52) for systolic blood pressure. These differences generated small effect sizes and were not clinically significant. Results were similar for patients who experienced changes in pain categories and for those conditions recognized to produce significant pain.ConclusionHealth care professionals cannot use vital signs to estimate or substantiate self-reported pain intensity levels or changes over time.

AbstractObjectivesAs an aging population continues to place strain on the health care system, many older adults are living with unmet social and medical needs. In response, Emergency Medical Services (EMS) have initiated programs that encourage paramedics to refer patients in need to community based support services. This qualitative study explores frontline paramedic experiences with referral programs to identify opportunities and challenges in their practice.MethodsThis study used an intepretivist qualitative study design involving interviews of frontline paramedics employed in a region where referral programs were in place. Interviews were semi-structured and one-on-one. Data were transcribed verbatim and analyzed using inductive open coding throughout, then grouped to identify themes. Data collection and analysis were conducted simultaneously and flexibly until saturation.ResultsTwenty-three interviews were conducted representing 6 regions. When participating with referral programs the data revealed that frontline paramedics appear to experience (a) role confusion, (b) an inadequate knowledge base, (c) inadequate feedback, (d) undefined accountability, and (e) strong patient advocacy.ConclusionsIn a strained health care system, EMS and paramedics have an opportunity to better serve patients by initiating referrals for patients they encounter with unmet social and medical needs. However, referral programs face a number of challenges that, if left poorly addressed, may threaten the success of such programs.
Statistical Studies of Supernova Environments

AbstractMapping the diversity of SNe to progenitor properties is key to our understanding of stellar evolution and explosive stellar death. Investigations of the immediate environments of SNe allow statistical constraints to be made on progenitor properties such as mass and metallicity. Here, we review the progress that has been made in this field. Pixel statistics using tracers of e.g. star formation within galaxies show intriguing differences in the explosion sites of, in particular SNe types II and Ibc (SNe II and SNe Ibc respectively), suggesting statistical differences in population ages. Of particular interest is that SNe Ic are significantly more associated with host galaxy Hα emission than SNe Ib, implying shorter lifetimes for the former. In addition, such studies have shown (unexpectedly) that the interacting SNe IIn do not explode in regions containing the most massive stars, which suggests that at least a significant fraction of their progenitors arise from the lower end of the core-collapse SN mass range. Host H ii region spectroscopy has been obtained for a significant number of core-collapse events, however definitive conclusions on differences between distinct SN types have to-date been elusive. Single stellar evolution models predict that the relative fraction of SNe Ibc to SNe II should increase with increasing metallicity, due to the dependence of mass-loss rates on progenitor metallicity. We present a meta-analysis of all current host H ii region oxygen abundances for CC SNe. It is concluded that the SN II to SN Ibc ratio shows little variation with oxygen abundance, with only a suggestion that the ratio increases in the lowest bin. Radial distributions of different SNe are discussed, where a central excess of SNe Ibc has been observed within disturbed galaxy systems, which is difficult to ascribe to metallicity or selection effects. Environment studies are also being undertaken for SNe Ia, where constraints can be made on the shortest delay times of progenitor systems. It is shown that ‘redder’ SNe Ia are more often found within star-forming regions. Environment studies are evolving to enable studies at higher spatial resolutions than previously possible, while in addition the advent of wide-field integral field unit instruments allows galaxy-wide spectral analyses which will provide fruitful results to this field. Some example contemporary results are shown in that direction.

AbstractWe present observations of the first 10° of longitude in the Mopra CO survey of the southern Galactic plane, covering Galactic longitude l = 320–330° and latitude b = ±0.5°, and l = 327–330°, b = +0.5–1.0°. These data have been taken at 35-arcsec spatial resolution and 0.1 km s−1 spectral resolution, providing an unprecedented view of the molecular clouds and gas of the southern Galactic plane in the 109–115 GHz J = 1–0 transitions of 12CO, 13CO, C18O, and C17O. Together with information about the noise statistics from the Mopra telescope, these data can be retrieved from the Mopra CO website and the CSIRO-ATNF data archive.

In the present study, the effects of partial substitution of dietary protein by digestible starch on endogenous glucose production were evaluated in European seabass (Dicentrarchus labrax). The fractional contribution of dietary carbohydratesv.gluconeogenesis to blood glucose appearance and hepatic glycogen synthesis was quantified in two groups of seabass fed with a diet containing 30 % digestible starch (DS) or without a carbohydrate supplement as the control (CTRL). Measurements were performed by transferring the fish to a tank containing water enriched with 5 %2H2O over the last six feeding days, and quantifying the incorporation of2H into blood glucose and hepatic glycogen by2H NMR. For CTRL fish, gluconeogenesis accounted for the majority of circulating glucose while for the DS fish, this contribution was significantly lower (CTRL 85 (sem4) %v.DS 54 (sem2) %;P< 0·001). Hepatic glycogen synthesis via gluconeogenesis (indirect pathway) was also significantly reduced in the DS fish, in both relative (CTRL 100 (sem1) %v.DS 72 (sem1) %;P< 0·001) and absolute terms (CTRL 28 (sem1)v.DS 17 (sem1) μmol/kg per h;P< 0·001). A major fraction of the dietary carbohydrates that contributed to blood glucose appearance (33 (sem1) % of the total 47 (sem2) %) had undergone exchange with hepatic glucose 6-phosphate. This indicated the simultaneous activity of hepatic glucokinase and glucose 6-phosphatase. In conclusion, supplementation of digestible starch resulted in a significant reduction of gluconeogenic contributions to systemic glucose appearance and hepatic glycogen synthesis.
