Abstract
Homologous recombination (HR) is the primary pathway for repairing double-strand DNA breaks implicating in the development of cancer. RNAi-based knockdowns of BRCA1 and RAD51 in this pathway have been performed to investigate the resulting transcriptomic profiles. Here we propose a computational framework to utilize these profiles to calculate a score, named RNA-Interference derived Proliferation Score (RIPS), which reflects cell proliferation ability in individual breast tumors. RIPS is predictive of breast cancer classes, prognosis, genome instability, and neoadjuvant chemosensitivity. This framework directly translates the readout of knockdown experiments into potential clinical applications and generates a robust biomarker in breast cancer.

Abstract
PURPOSE The efficacy of an Image Gently(®)/Image Wisely(®) radiology departmental campaign consisting of the optimization of CT protocols to reduce dose while maintaining quality, and an educational effort to alter the ordering patterns of referring physicians at a multihospital academic center, was evaluated. METHODS The numbers of CT, MR, and ultrasound studies performed at inpatient, outpatient, and emergency facilities in the hospital system before and after the initiation of the departmental campaign (2010) were obtained for a 10-year period (2004-2014) using a radiology information system. For the same time period, dose per scan (volumetric CT dose index) was obtained through the Dose Index Registry(®)/National Radiology Data Registry for frequently performed studies. Descriptive statistics were used to analyze temporal trends in radiation dose and utilization across differing age groups: <20, 20 to 39, and 40 to 59 years. RESULTS The radiology information system yielded 865,879 imaging examinations and 4,508,030 patients. Although patient and imaging volume grew annually over the study period (by 6.8% and 4.9%, respectively), CT utilization as a percentage of total imaging decreased, compensated for by an increase in ultrasound use. This was most marked in the youngest age group. MR use as a percentage of total imaging was unchanged. The median volumetric CT dose index for each study protocol was reduced or stabilized. CONCLUSIONS The campaign resulted in a reduction in CT utilization, a reduction in radiation dose per study, and a compensatory rise in ultrasound use. An interactive aggressive educational campaign directed toward referring providers combined with protocol dose reduction efforts can be successful in reducing patient exposure from medical radiation.

Abstract
BACKGROUND Standardized methodologies for assessing economic burden of injury at the national or international level do not exist. OBJECTIVE To measure national incidence, medical costs, and productivity losses of medically treated injuries using the most recent data available in the United States, as a case study for similarly developed countries undertaking economic burden analyses. METHOD The authors combined several data sets to estimate the incidence of fatal and non-fatal injuries in 2000. They computed unit medical and productivity costs and multiplied these costs by corresponding incidence estimates to yield total lifetime costs of injuries occurring in 2000. MAIN OUTCOME MEASURES Incidence, medical costs, productivity losses, and total costs for injuries stratified by age group, sex, and mechanism. RESULTS More than 50 million Americans experienced a medically treated injury in 2000, resulting in lifetime costs of $406 billion; $80 billion for medical treatment and $326 billion for lost productivity. Males had a 20% higher rate of injury than females. Injuries resulting from falls or being struck by/against an object accounted for more than 44% of injuries. The rate of medically treated injuries declined by 15% from 1985 to 2000 in the US. For those aged 0-44, the incidence rate of injuries declined by more than 20%; while persons aged 75 and older experienced a 20% increase. CONCLUSIONS These national burden estimates provide unequivocal evidence of the large health and financial burden of injuries. This study can serve as a template for other countries or be used in intercountry comparisons.

Abstract
Background The present interdisciplinary consensus review proposes clinical considerations and recommendations for anaesthetic practice in patients undergoing gastrointestinal surgery with an Enhanced Recovery after Surgery (ERAS) programme. Methods Studies were selected with particular attention being paid to meta‐analyses, randomized controlled trials and large prospective cohort studies. For each item of the perioperative treatment pathway, available English‐language literature was examined and reviewed. The group reached a consensus recommendation after critical appraisal of the literature. Results This consensus statement demonstrates that anaesthesiologists control several preoperative, intraoperative and postoperative ERAS elements. Further research is needed to verify the strength of these recommendations. Conclusions Based on the evidence available for each element of perioperative care pathways, the Enhanced Recovery After Surgery (ERAS ®) Society presents a comprehensive consensus review, clinical considerations and recommendations for anaesthesia care in patients undergoing gastrointestinal surgery within an ERAS programme. This unified protocol facilitates involvement of anaesthesiologists in the implementation of the ERAS programmes and allows for comparison between centres and it eventually might facilitate the design of multi‐institutional prospective and adequately powered randomized trials.

Abstract
Lung transplantation (LTx) is a therapeutic option for severe pulmonary arterial hypertension (PAH) patients failing optimal medical therapy. The use of donation after circulatory determination of death (DCDD) donor lungs for PAH LTx has rarely been reported, primarily reflecting concerns that DCDD lungs represent extended criteria donors, at risk of morbidity and mortality. A retrospective study of all Alfred Hospital DCDD and DNDD (donation after neurologic determination of death) PAH LTx was undertaken. Protocolized fluid/inotrope/ventilator and extracorporeal membrane oxygenation (ECMO) strategies were utilized. Since our first DCDD LTx in 2006, 512 LTx have been performed. Of 31 PAH recipients, 11 received DCDD lungs (11% of DCDD LTx) and 20 received DNDD lungs (5% of DNDD LTx) (p = 0.04). Only one PAH patient died on the LTx waiting list. Peri-LTx ECMO was utilized in 3/11 (27%) DCDD and 6/20 (30%) DNDD PAH LTx (p = 0.68). Primary graft dysfunction, intensive care, and overall stay were the same in both groups. Survival at 1 and 8 years was 100% and 80% for DCDD versus 100% and 70% for DNDD LTx (p = 0.88), respectively. In conclusion, excellent results can be achieved for PAH LTx. DCDD donor lungs are not extended lungs per se having passed the toughest test.

Abstract
Despite numerous therapies that effectively inhibit estrogen signaling in breast cancer, a significant proportion of patients with estrogen receptor (ER)-positive malignancy will succumb to their disease. Herein we demonstrate that long-term estrogen deprivation (LTED) therapy among ER-positive breast cancer cells results in the adaptive increase in ER expression and subsequent activation of multiple tyrosine kinases. Combination therapy with the ER down-regulator fulvestrant and dasatinib, a broad kinase inhibitor, exhibits synergistic activity against LTED cells, by reduction of cell proliferation, cell survival, cell invasion and mammary acinar formation. Screening kinase phosphorylation using protein arrays and functional proteomic analysis demonstrates that the combination of fulvestrant and dasatinib inhibits multiple tyrosine kinases and cancer-related pathways that are constitutively activated in LTED cells. Because LTED cells display increased insulin receptor (InsR)/insulin-like growth factor 1 receptor (IGF-1R) signaling, we added an ant-IGF-1 antibody to the combination with fulvestrant and dasatinib in an effort to further increase the inhibition. However, adding MK0646 only modestly increased the inhibition of cell growth in monolayer culture, but neither suppressed acinar formation nor inhibited cell migration in vitro and invasion in vivo. Therefore, combinations of fulvestrant and dasatinib, but not MK0646, may benefit patients with tyrosine-kinase-activated, endocrine therapy-resistant breast cancer.

Abstract
Circular dichroism (CD) observed by photoemission, being sensitive to the orbital and spin angular momenta of the electronic states, is a powerful probe of the nontrivial surface states of topological insulators, but the experimental results thus far have eluded a comprehensive description. We report a study of Bi2Te3 films with thicknesses ranging from one quintuple layer (two-dimensional limit) to 12 layers (bulk limit) over a wide range of incident photon energy. The data show complex variations in magnitude and sign reversals, which are nevertheless well described by a theoretical calculation including all three photoemission mechanisms: dipole transition, surface photoemission, and spin-orbit coupling. The results establish the nontrivial connection between the spin-orbit texture and CD.

Abstract
BACKGROUND Hospital admissions for back pain are prolonged, costly, and common. Epidural steroid injections are frequently performed in an outpatient setting with an excellent safety and efficacy profile. OBJECTIVES The purpose was to review data from patients with severe pain that did not respond to aggressive medical treatment in the emergency department (ED) and determine the effectiveness of an interlaminar epidural steroid injection (ESI) in this patient population. STUDY DESIGN Retrospective matched cohort design. SETTING Single urban emergency department at a tertiary referral center. METHODS A retrospective cohort comparison pairing 2 groups that both failed aggressive pain control in the ED was performed. The epidural injection group (1ESI) received an interlaminar ESI while in the ED. The standard therapy group (2ST) was admitted for medical pain management. Groups were matched for pain intensity, age, and symptom duration. RESULTS Thirty-five patients in 1ESI (NRS 8.8, 5 - 10, 0.35), and 28 patients in 2ST (NRS 8.9, 4 - 10, 1.7). Pain score after ESI 0.33 (0 - 2, 0.6); all were discharged. Pain score on day 1 of hospital admission for 2ST was 8.7 (7 - 10, 1.5). Total ED time was 8 hours for 1ESI and 13 hours for 2ST (P < 0.002). 1ESI patients received less narcotics while in the ED (P < 0.002) and were discharged home with less narcotics than 2ST (< 0.002). Average inpatient length of stay (LOS) for 2ST was 5 (1.5 - 15, 3.3) days. Cost of care was over 6 times greater for those patients admitted for pain management (P < 0.001). LIMITATIONS Retrospective design, non-randomized sample, and a small patient population. CONCLUSION An ED patient cohort with severe refractory pain was treated with an interlaminar ESI after failing maximal medical pain management while in the ED. Complete pain relief was achieved safely and rapidly. The need for inpatient admission was eliminated after injection. Costs were lower in the group that received an epidural injection. Narcotic requirements upon discharge were decreased as well.

Abstract
Peer networks including social groups using typical peers, scripted instruction, visual text cues, and reinforcement were examined with students with autism spectrum disorders (ASD). A multiple baseline design across four participants was used to measure students’ use of communication acts with peers during free play following instruction. Peer Network groups occurred over a 3-month period for 30 min 3 times per week. Visual inspection of trends and TauU effect size calculations showed significant changes in total communication acts for all four participants during peer network sessions and increased initiations for three of the four participants. Generalization probes during classroom centers indicated increased communications following interventions for three of the four participants.

Abstract
To sustain natural systems, there must be an ongoing balance between environmental, social, and economic considerations. A key element of sustainability theory is to identify the most vulnerable surroundings. The most vulnerable knee tissue is the articular cartilage as it is the last line of osteoarthritis (OA) defense. This tissue has a poor capacity for healing. Based on sustainability theory and social ecology concepts we propose that several key factors contribute to knee function preservation. Factors include health history, genetic predisposition, personal behaviors, and socio-environmental factors in addition to local-regional-global physiological system function. Addressing only some of these factors or any one factor in isolation may lead to less than optimal treatment effectiveness. The purpose of this commentary is to introduce a medical, surgical and rehabilitation management approach for patients with knee OA that considers more than physical function improvement. This approach also considers social, emotional, and environmental factors to better ensure patient satisfaction, fulfilled expectations and successful outcomes. A clinical care pathway is presented for a 57-year-old patient with medial compartment knee OA who is contemplating early arthroplasty versus a knee function preservation treatment approach. Early arthroplasty refers to high revision likelihood based on a minimum 15 year prosthesis life-expectancy.

Abstract
Recess plays an integral role in the social and emotional development of children given the time provided to engage in interactions with others and practice important social skills. Students with ASD, however, typically fail to achieve even minimal benefit from recess due to social and communication impairments as well as a tendency to withdraw. Implementation of evidence-based interventions such as peer-mediated social skills groups, are necessary to ensure recess is an advantageous learning environment for students with ASD. A multiple-baseline design across participants was used to determine if a functional relationship exists between a social skills instructional program combined with peer networks with school staff as implementers and increases in level of communicative acts for participants with ASD at recess. Results indicate all participants demonstrated an immediate increase in the number of communicative acts with the introduction of the intervention. Implications for practice are discussed.

Abstract
The screening and detection of recurrent medulloblastoma presents the clinician with significant diagnostic challenges, including the risk of misdiagnosis. The authors present the case of a young girl with a history of a treated standard-risk medulloblastoma that highlights the risk of assuming recurrence has occurred when clinical and/or imaging changes are observed. This girl developed both new clinical deficits and had radiographic evidence of recurrence. She subsequently experienced a complete resolution of symptoms and radiographic findings with steroids alone.

Abstract
BACKGROUND Niacin has lipid-modifying efficacy and cardiovascular benefit, but is underutilised because of niacin-induced flushing (NIF). This real-world, prospective, observational study characterised the severity and impact of NIF symptoms among participants who were newly prescribed extended-release (ER) niacin. METHODS Participants were surveyed daily during week 1 of therapy, at weeks 5, 9, 13, and at months 7, 10 and 13. Surveys included the Flushing Symptom Questionnaire (FSQ), which includes the Global Flushing Severity Score (GFSS) question, the Flushing Impact Questionnaire (FIQ) and the Treatment Satisfaction Questionnaire for Medication (TSQM). RESULTS Overall, 306 participants were enrolled. During week 1, 30.0% of participants reported a maximum GFSS ≥ 4 (moderate or greater). Mean FIQ domain scores increased with increasing flushing severity, primarily driven by the Irritation/Frustration domain. By week 13, only 2.5% of participants had attained a 2 g ER niacin dose. By month 13, 43.5% (n = 133) had discontinued ER niacin. At discontinuation, only 3.1% of participants had attained the 2 g dose. Over half of the participants who discontinued experienced flushing symptoms: 82% reported moderate to extreme flushing (GFSS ≥ 4), and 68% reported severe to extreme flushing (GFSS ≥ 7). Participants who discontinued and had flushing side effects reported high degrees of impact in the FIQ Irritation/Frustration domain, and high dissatisfaction as a result of side effects, as measured by the TSQM. CONCLUSION In a real-world setting, NIF side effects were bothersome and had an impact on the continuation of therapy.

Abstract
Absent sella turcica is an extremely rare and dramatic radiographic finding. It may be isolated or occur in the presence of other anomalies, often involving the adenohypophysis. Our evaluation of a female infant with multiple anomalies including absence of the sella turcica, a normal pituitary in the craniopharyngeal canal, normal pituitary function, choanal atresia and anomalies of the appendiceal skeleton prompted a review of the occurrence and biology of an absent sella turcica.

Abstract
We present a seminal set of experiments on dense granular flows in the stadium shear geometry. The advantage of this geometry is that it produces steady shear flow over large deformations, in which the shear stress is constant. The striking result is that the velocity profiles exhibit an S shape, and are not linear as local constitutive laws would predict. We propose a model that suggests this is a result of wall perturbations which span through the system due to the nonlocal behavior of the material. The model is analogous to that of eddy viscosity in turbulent boundary layers, in which the distance to the wall is introduced to predict velocity profiles. Our findings appear pivotal in a number of experimental and practical situations involving dense granular flows next to a boundary. They could further be adapted to other similar materials such as dense suspensions, foams, or emulsions.
