Abstract
Redox-active catechols are bioinspired precursors for ortho-quinones that are characterized by higher discharge potentials than para-quinones, the latter being extensively used as organic cathode materials for lithium ion batteries (LIBs). Here, this study demonstrates that the rational molecular design of copolymers bearing catechol- and Li+ ion-conducting anionic pendants endow redox-active polymers (RAPs) with ultrarobust electrochemical energy storage features when combined to carbon nanotubes as a flexible, binder-, and metal current collector-free buckypaper electrode. The importance of the structure and functionality of the RAPs on the battery performances in LIBs is discussed. The structure-optimized RAPs can store high-capacities of 360 mA h g-1 at 5C and 320 mA h g-1 at 30C in LIBs. The high ion and electron mobilities within the buckypaper also enable to register 96 mA h g-1 (24% capacity retention) at an extreme C-rate of 600C (6 s for total discharge). Moreover, excellent cyclability is noted with a capacity retention of 98% over 3400 cycles at 30C. The high capacity, superior active-material utilization, ultralong cyclability, and excellent rate performances of RAPs-based electrode clearly rival most of the state-of-the-art Li+ ion organic cathodes, and opens up new horizons for large-scalable fabrication of electrode materials for ultrarobust Li storage.

Abstract
BACKGROUND Interleukin (IL)-33 is implicated in the pathophysiology of asthma and allergic diseases. However, our knowledge is limited regarding how IL-33 release is controlled. The transcription factor nuclear factor-erythroid-2-related factor 2 (Nrf2) plays a key role in antioxidant response regulation. OBJECTIVE The goal of this project was to investigate the role of cellular oxidative stress in controlling IL-33 release in airway epithelium. METHODS Complementary approaches were used that included human bronchial epithelial cells and mouse models of airway type-2 immunity that were exposed to fungus Alternaria extract. The clinically available Nrf2 activator 2-cyano-3,12-dioxooleana-1,9-dien-28-oic acid methyl ester (CDDO-Me) was used to evaluate the role of Nrf2-induced antioxidant molecules. RESULTS Human bronchial epithelial cells produced reactive oxygen species (ROS) when they were exposed to Alternaria extract. ROS scavengers, such as glutathione (GSH) and N-acetyl cysteine, prevented extracellular secretion of ATP and increases in intracellular calcium concentrations that precede IL-33 release. Administration of CDDO-Me to mice enhanced expression of a number of antioxidant molecules in the lungs and elevated lung levels of endogenous GSH. Importantly, CDDO-Me treatment reduced allergen-induced ATP secretion and IL-33 release by airway epithelial cells in vitro and protected mice from IL-33 release and asthma-like pathological changes in the lungs. CONCLUSIONS The balance between oxidative stress and antioxidant responses plays a key role in controlling IL-33 release in airway epithelium. The therapeutic potential of Nrf2 activators needs to be considered for asthma and allergic airway diseases.

Abstract
Epistaxis represents the most common ENT emergency and its management has been a focus of audit recently, with consideration given to the associated economic burden. The aim of our study is to evaluate the management of epistaxis in terms of treatments used, duration of stay, recurrence and cost. A retrospective review of hospital inpatient enquiry (HIPE) data from a single secondary referral centre was undertaken during a four year period. Four hundrefd and thirty-four patients were identified. The majority (n= 262, 60.3%) were male and the average age was 64.2 years. The vast majority (n=362, 83.4%) were managed non-operatively. Only 15 patients (3.4%) were managed surgically. The average length of stay was 2.5 days and did not vary greatly between the treatment groups. The recurrence rate was 8.2% (n=36). Approximate costs of packing vs EUA and cautery suggest that packing alone is more economical but more data is needed to fully compare the options.

Abstract
BACKGROUND Oral cavity cancer is the most common cancer among rural India. There is a paucity of data for outcomes of operable oral cavity cancer from rural India. Use of maintenance metronomic may delay or avoid relapse. AIM To evaluate outcomes of operable oral cavity carcinoma and evaluate impact of maintenance metronomic chemotherapy. OBJECTIVES To evaluate disease-free survival (DFS), overall survival (OS), and factors affecting the outcome in operable oral cavity cancer. MATERIALS AND METHODS Data of patients diagnosed with oral cavity cancer registered between May 2008 and May 2014 were retrieved. Only those patients with operable oral cavity cancer and upfront definitive surgery were included in the study. Demographic profile, stage, tobacco consumption, adjuvant therapy, and pattern of failure were collected. Kaplan-Meir survival analysis was used to determine DFS and OS. Log-rank test was used to evaluate factors affecting outcome. RESULTS Median follow-up is 24 months. Out of 335 patients, 225 (67%) had advanced operable cancer with 42/225 (18%) and 183/225 (82%) as Stages III and IVA, respectively. Buccal mucosa was the most common subsite (178/335, 53%) followed by tongue (63/335, 19%). Ninety-two percent patients were addicted to smokeless tobacco, whereas 27% were smokers. Median DFS is 13 months with 2 years relative DFS 32%. Median OS is 30 months, with 2 years OS of 54%. Metronomic adjuvant oral chemotherapy was given in 130/225 (58%); Stage III and IVA patients with median of 14 months (3-18 months). Use of metronomic chemotherapy improved DFS (8 vs. 14 months, P = 0.22) and OS (14 vs. 26 months, P = 0.04). CONCLUSION Oral cavity cancer is a major health care problem in rural India. Presentation at advanced stage leads to suboptimal outcomes. Benefit of metronomic maintenance chemotherapy in locally advanced oral cavity needs to be further evaluated prospectively.

Abstract
OBJECTIVE To determine, by evaluation of histological slides, images and descriptions of early (second-trimester) placenta accreta (EPA) and placental implantation in cases of Cesarean scar pregnancy (CSP), whether these are pathologically indistinguishable and whether they both represent different stages in the disease continuum leading to morbidly adherent placenta in the third trimester. METHODS The database of a previously published review of CSP and EPA was used to identify articles with histopathological descriptions and electronic images for pathological review. When possible, microscopic slides and/or paraffin blocks were obtained from the original researchers. We also included from our own institutions cases of CSP and EPA for which pathology specimens were available. Two pathologists examined all the material independently and, blinded to each other's findings, provided a pathological diagnosis based on microscopic appearance. Interobserver agreement in diagnosis was determined. RESULTS Forty articles were identified, which included 31 cases of CSP and 13 cases of EPA containing histopathological descriptions and/or images of the pathology. We additionally included six cases of CSP and eight cases of EPA from our own institutions, giving a total of 58 cases available for histological evaluation (37 CSP and 21 EPA) containing clear definitions of morbidly adherent placenta. In the 29 cases for which images/slides were available for histopathological evaluation, both pathologists attested to the various degrees of myometrial and/or scar tissue invasion by placental villi with scant or no intervening decidua, consistent with the classic definition of morbidly adherent placenta. Based on the reviewed material, cases with a diagnosis of EPA and those with a diagnosis of CSP showed identical histopathological features. Interobserver correlation was high (kappa = 0.93). CONCLUSIONS EPA and placental implantation in CSP are histopathologically indistinguishable and may represent different stages in the disease continuum leading to morbidly adherent placenta in the third trimester.

Abstract
BACKGROUND Certain jurisdictions in Canada legally require that physicians report unfit drivers. Physician attitudes and patterns of practice have yet to be evaluated in Canada for patients with brain tumours. METHODS We conducted a survey of 97 radiation oncologists, eliciting demographics, knowledge of reporting laws, and attitudes on reporting guidelines for unfit drivers. Eight scenarios with varying disability levels were presented to determine the likelihood of a patient being reported as unfit to drive. Statistical comparisons were made using the Fisher exact test. RESULTS Of physicians approached, 99% responded, and 97 physicians participated. Most respondents (87%) felt that laws in their province governing the reporting of medically unfit drivers were unclear. Of the responding physicians, 23 (24%) were unable to correctly identify whether their province had mandatory reporting legislation. Physicians from provinces without mandatory reporting legislation were significantly less likely to consider reporting patients to provincial authorities (p = 0.001), and for all clinical scenarios, the likelihood of reporting significantly depended on the physician's provincial legal obligations. CONCLUSIONS The presence of provincial legislation is of primary importance in determining whether physicians will report brain tumour patients to drivers' licensing authorities. In Canada, clear guidelines have to be developed to help in the assessment of whether brain tumour patients should drive.
