Abstract
OBJECTIVE Decision-making regarding level of lower extremity amputation is sometimes challenging. Selecting an appropriate anatomic level for major amputation requires consideration of tradeoffs between postoperative function and risk of wound complications that may require additional operations, including debridement and/or conversion to above-knee amputation (AKA). We evaluated the utility of common, non-invasive diagnostic tests used in clinical practice to predict the need for reoperations among patients undergoing primary, elective below knee-amputations (BKAs) by vascular surgeons. METHODS Patients undergoing elective BKA over a 5-year period were identified using Current Procedural Terminology codes. Medical records were reviewed to characterize demographics, pre-amputation testing transcutaneous oxygen tension (TcPO2), and ankle-brachial index (ABI). The need for ipsilateral post-BKA reoperation (including BKA revision and/or conversion to AKA) regardless of indication was the primary outcome. Associations were evaluated using univariable and multivariable logistic regression models. Cutpoints for TcPO2 values associated with amputation reoperation were evaluated using receiver operating characteristic curves. RESULTS We identified 175 BKAs, of which 46 (26.3%) required ipsilateral reoperation (18.9% BKA revisions and 14.3% conversions to AKA). The mean age was 63.3 ± 14.8 years. Most patients were male (65.1%) and White (72.0%). Mean pre-amputation calf TcPO2 was 40.0 ± 20.5 mmHg, and mean ABI was 0.64 ± 0.45. In univariable models, post-BKA reoperation was associated with calf TcPO2 (odds ratio [OR], 0.97; 95% confidence interval [CI], 0.94-0.99; P = .013) but not ABI (OR, 0.53; 95% CI, 0.19-1.46; P = .217). Univariable associations with reoperation were also identified for age (OR, 0.97; 95% CI, 0.94-0.990; P = .003) and diabetes (OR, 0.43; 95% CI, 0.21-0.87; P = .019). No associations with amputation revision were identified for gender, race, end-stage renal disease, or preoperative antibiotics. Calf TcPO2 remained associated with post-BKA reoperation in a multivariable model (OR, 0.97; 95% CI, 0.94-0.99; P = .022) adjusted for age (OR, 0.98; 95% CI, 0.94-1.01; P = .222) and diabetes (OR, 0.98; 95% CI, 0.94-1.01; P = .559). Receiver operating characteristic analysis suggested a TcPO2 ≥38 mmHg as an appropriate cut-point for assessing risk for BKA revision (area under the curve = 0.682; negative predictive value, 0.91). CONCLUSIONS Reoperation after BKA is common, and reoperation risk was associated with pre-amputation TcPO2. For patients undergoing elective BKA, higher risk of reoperation should be discussed with patients with an ipsilateral TcPO2 <38 mmHg.

Abstract
We describe a novel sequestrate genus and species, Asperosporus subterraneus gen. et sp. nov., found associated with nursery production of ferns in south Florida. This truffle species has a unique combination of morphological characters among described Agaricaceae in that it lacks a stipe or columella, has large, ornamented spores, the fresh sporocarps rapidly stain pink-red when cut or bruised, and they have a rancid smell. Although this fungus does not appear to be a direct plant pathogen, the hyphae of A. subterraneus produce a thick hydrophobic mycelial mat that binds the organic matter and therefore prevents water and fertilizer from being absorbed by plants, consequently causing wilting and chlorosis. Using morphological characteristics and phylogenetic reconstruction based on the internal transcribed spacer (ITS), partial large subunit nuclear ribosomal DNA (LSU), second largest subunit of RNA polymerase II (rpb2) and translation elongation factor 1-alpha (tef1) regions, we describe this taxon as a new genus and species in Agaricaceae.

Abstract
OBJECTIVE To characterize the relationship between office-based laboratory (OBL) use and Medicare payments for peripheral vascular interventions (PVI). METHODS Using the Centers for Medicare and Medicaid Services Provider Utilization and Payment Data Public Use Files from 2014 to 2017, we identified providers who performed percutaneous transluminal angioplasty, stent placement, and atherectomy. Procedures were aggregated at the provider and hospital referral region (HRR) level. RESULTS Between 2014 and 2017, 2641 providers performed 308,247 procedures. The mean payment for OBL stent placement in 2017 was $4383.39, and mean payment for OBL atherectomy was $13,079.63. The change in the mean payment amount varied significantly, from a decrease of $16.97 in HRR 146 to an increase of $43.77 per beneficiary over the study period in HRR 11. The change in the rate of PVI also varied substantially, and moderately correlated with change in payment across HRRs (R2 = 0.40; P < .001). The majority of HRRs experienced an increase in rate of PVI within OBLs, which strongly correlated with changes in payments (R2 = 0.85; P < .001). Furthermore, 85% of the variance in change in payment was explained by increases in OBL atherectomy (P < .001). CONCLUSIONS A rapid shift into the office setting for PVIs occurred within some HRRs, which was highly geographically variable and was strongly correlated with payments. Policymakers should revisit the current payment structure for OBL use and, in particular atherectomy, to better align the policy with its intended goals.

Abstract
Despite being one of the most consumed vegetables in the United States, the elemental profile of sweet corn (Zea mays L.) is limited in its dietary contributions. To address this through genetic improvement, a genome-wide association study was conducted for the concentrations of 15 elements in fresh kernels of a sweet corn association panel. In concordance with mapping results from mature maize kernels, we detected a probable pleiotropic association of zinc and iron concentrations with nicotianamine synthase5 (nas5), which purportedly encodes an enzyme involved in synthesis of the metal chelator nicotianamine. In addition, a pervasive association signal was identified for cadmium concentration within a recombination suppressed region on chromosome 2. The likely causal gene underlying this signal was heavy metal ATPase3 (hma3), whose counterpart in rice, OsHMA3, mediates vacuolar sequestration of cadmium and zinc in roots, whereby regulating zinc homeostasis and cadmium accumulation in grains. In our association panel, hma3 associated with cadmium but not zinc accumulation in fresh kernels. This finding implies that selection for low cadmium will not affect zinc levels in fresh kernels. Although less resolved association signals were detected for boron, nickel, and calcium, all 15 elements were shown to have moderate predictive abilities via whole-genome prediction. Collectively, these results help enhance our genomics-assisted breeding efforts centered on improving the elemental profile of fresh sweet corn kernels.

Abstract
Importance Various clinical societies and patient advocacy organizations continue to encourage minimum volume standards at hospitals that perform certain high-risk operations. Although many clinicians and quality and safety experts believe this can improve outcomes, the extent to which hospitals have responded to these discretionary standards remains unclear. Objective To evaluate the association between short-term clinical outcomes and hospitals' adherence to the Leapfrog Group's minimum volume standards for high-risk cancer surgery. Design, Setting, and Participants Longitudinal cohort study using 100% of the Medicare claims for 516 392 patients undergoing pancreatic, esophageal, rectal, or lung resection for cancer between January 1, 2005, and December 31, 2016. Data were accessed between December 1, 2018, and April 30, 2019. Exposures High-risk cancer surgery in hospitals meeting and not meeting the minimum volume standards. Main Outcomes and Measures Patients having surgery in hospitals meeting the volume standard and 30-day and in-hospital mortality and complication rates. Results Overall, a total of 516 392 procedures (47 318 pancreatic resections, 29 812 esophageal resections, 116 383 rectal resections, and 322 879 lung resections) were included in the study, and patient mean (SD) age was 73.1 (7.5) years. Outcomes improved over time in both hospitals meeting and not meeting the minimum volume standards. Mortality after pancreatic resection decreased from 5.5% in 2005 to 4.8% in 2016 (P for trend <.001). Mortality after esophageal resection decreased from in 6.7% 2005 to 5.0% in 2016 (P for trend <.001). Mortality after rectal resection decreased from 3.6% in 2005 to 2.7 % in 2016 (P for trend <.001). Mortality after lung resection decreased from 4.2% in 2005 to 2.7 % in 2016 (P for trend <.001). Throughout the study period, there were no statistically significant differences in risk-adjusted mortality between hospitals meeting and not meeting the volume standards for esophageal, lung, and rectal cancer resections. Mortality rates after pancreatic resection were consistently lower at hospitals meeting the volume standard, although mortality at all hospitals decreased over the study period. For example, in 2016, risk-adjusted mortality rates for hospitals meeting the volume standard were 3.8% (95% CI, 3.3%-4.3%) compared with 5.7% (95% CI, 5.1%-6.5%) for hospitals that did not. Although an increasing majority of patients underwent surgery in hospitals meeting the Leapfrog volume standards over time, the overall proportion of hospitals meeting the standards in 2016 ranged from 5.6% for esophageal resection to 23.3% for pancreatic resection. Conclusions and Relevance Although volume remains an important factor for patient safety, the Leapfrog Group's minimum volume standards did not differentiate hospitals based on mortality for 3 of the 4 high-risk cancer operations assessed, and few hospitals were able to meet these standards. These findings highlight important tradeoffs between setting effective volume thresholds and practical expectations for hospital adherence and patient access to centers that meet those standards.

Abstract
BACKGROUND To address overuse of unnecessary practices, several surgical organizations have participated in the Choosing Wisely® campaign and identified four breast cancer surgical procedures as unnecessary. Despite evidence demonstrating no survival benefit for all four, evidence suggests only two have been substantially de-implemented. Our objective was to understand why surgeons stop performing certain unnecessary cancer operations but not others and how best to de-implement entrenched and emerging unnecessary procedures. METHODS We sampled surgeons who treat breast cancer in a variety of practice types and geographic regions in the United States. Using a semi-structured guide, we conducted telephone interviews (n = 18) to elicit attitudes and understand practices relating to the four identified breast cancer procedures in the Choosing Wisely® campaign. Interviews were recorded, transcribed, and anonymized. Transcripts were analyzed using inductive and deductive thematic analysis. RESULTS For the two procedures successfully de-implemented, surgeons described a high level of confidence in the data supporting the recommendations. In contrast, surgeons frequently described a lack of familiarity or skepticism toward the recommendation to avoid sentinel-node biopsy in women ≥ 70 years of age and the influence of other collaborating oncology providers as justification for continued use. Regarding contralateral prophylactic mastectomy, surgeons consistently agreed with the recommendation that this was unnecessary, yet reported continued utilization due to the value placed on patient autonomy and preference. CONCLUSIONS With a growing focus on the elimination of ineffective, unproven or low value practices, it is imperative that the behavioral determinants are understood and targeted with specific interventions to decrease utilization rapidly.

Abstract
Sweet corn (Zea mays L.) is highly consumed in the United States, but does not make major contributions to the daily intake of carotenoids (provitamin A carotenoids, lutein and zeaxanthin) that would help in the prevention of health complications. A genome-wide association study of seven kernel carotenoids and twelve derivative traits was conducted in a sweet corn inbred line association panel ranging from light to dark yellow in endosperm color to elucidate the genetic basis of carotenoid levels in fresh kernels. In agreement with earlier studies of maize kernels at maturity, we detected an association of β-carotene hydroxylase (crtRB1) with β-carotene concentration and lycopene epsilon cyclase (lcyE) with the ratio of flux between the α- and β-carotene branches in the carotenoid biosynthetic pathway. Additionally, we found that 5% or less of the evaluated inbred lines possessing the shrunken2 (sh2) endosperm mutation had the most favorable lycE allele or crtRB1 haplotype for elevating β-branch carotenoids (β-carotene and zeaxanthin) or β-carotene, respectively. Genomic prediction models with genome-wide markers obtained moderately high predictive abilities for the carotenoid traits, especially lutein, and outperformed models with less markers that targeted candidate genes implicated in the synthesis, retention, and/or genetic control of kernel carotenoids. Taken together, our results constitute an important step toward increasing carotenoids in fresh sweet corn kernels.

Abstract
β'-Sialons (Si6-zAlzOzN8-z, where 0 ≤ z ≤ ∼4.2) are studied using a combination of 29Si and 27Al solid-state NMR, using magnetic fields of up to 20 T, powder X-ray diffraction, and density functional theory (DFT) calculations of both the structure and NMR parameters. Four different structural models have been proposed in the literature for the replacement of silicon and nitrogen by aluminum and oxygen within a β-Si3N4-structured lattice. Experimental data are presented for the variation with composition (z) of the unit cell parameters from diffraction and the local coordination units present suggested by NMR data. The experimental data are compared to the changes with composition in the DFT calculations of the structure and the NMR parameters according to the four models, allowing the models to be distinguished. It is shown that only one of these, the domain model, is fully consistent with all of the experimental data and is, therefore, a good structural model for β'-sialons. More speculatively, it is suggested that for the domain model, 27Al NMR data might provide a constraint on the thickness of its aluminum-rich layers.

Abstract
BACKGROUND Although bariatric surgery is an effective treatment for obesity, utilization of bariatric procedures in older adults remains low. Previous work reported higher morbidity in older patients undergoing bariatric surgery. However, the generalizability of these data to contemporary septuagenarians is unclear. OBJECTIVES We sought to evaluate differences in 30-day outcomes, 1-year weight loss, and co-morbidity remission after bariatric surgery among 3 age groups as follows: <45 years, 45-69 years, and ≥70 years. SETTING Statewide quality improvement collaborative. METHODS Using a large quality improvement collaborative, we identified patients undergoing sleeve gastrectomy (SG) or Roux-en-Y gastric bypass (RYGB) between 2006 and 2018. We used multivariable logistic regression models to evaluate the association between age cohorts and 30-day outcomes, 1-year weight loss, and co-morbidity remission. RESULTS We identified 641 septuagenarians who underwent SG (68.5%) or RYGB (31.5%). Compared with 45-69 year olds, septuagenarians had higher rates of hemorrhage (5.1% versus 3.1%; P = .045) after RYGB and higher rates of leak/perforation (.9% versus .3%; P = .044) after SG. Compared with younger patients, septuagenarians lost less of their excess weight, losing 64.8% after RYGB and 53.8% after SG. Remission rates for diabetes and obstructive sleep were similar for patients aged ≥70 years and 45-69 years. CONCLUSIONS Bariatric surgery in septuagenarians results in substantial weight loss and co-morbidity remission with an acceptable safety profile. Surgeons with self-imposed age limits should consider broadening their selection criteria to include patients ≥70 years old.

Abstract
The conformational transition of a fluorinated amphiphilic dendrimer is monitored by the 1 H signal from water, alongside the 19 F signal from the dendrimer. High-field NMR data (chemical shift δ, self-diffusion coefficient D, longitudinal relaxation rate R1 , and transverse relaxation rate R2 ) for both dendrimer (19 F) and water (1 H) match each other in detecting the conformational transition. Among all parameters for both nuclei, the water proton transverse-relaxation rate R2 (1 H2 O) displays the highest relative scale of change upon conformational transition of the dendrimer. Hydrogen/deuterium-exchange mass spectrometry reveals that the compact form of the dendrimer has slower proton exchange with water than the extended form. This result suggests that the sensitivity of R2 (1 H2 O) toward dendrimer conformation originates, at least partially, from the difference in proton exchange efficiency between different dendrimer conformations. Finally, we also demonstrated that this conformational transition could be conveniently monitored using a low-field benchtop NMR spectrometer via R2 (1 H2 O). The 1 H2 O signal thus offers a simple way to monitor structural changes of macromolecules using benchtop time-domain NMR.

Abstract
Failure to rescue-mortality following a major surgical complication-is a key driver of variation in postoperative mortality. However, little is known about the impact of interpersonal and organizational dynamics, or microsystem factors, on failure to rescue. In a qualitative study of providers from hospitals with high and low rescue rates, we identified five key factors that providers believe influence the successful rescue of surgical patients: teamwork, action taking, psychological safety, recognition of complications, and communication. Near-uniform agreement existed on two targets for improvement: delayed recognition of developing complications and poor interprofessional communication and inability to express clinical concerns. To improve perioperative outcomes, hospitals and payers should shift their attention to improving early detection and effective communication of major complications.

Abstract
BACKGROUND A ruptured abdominal aortic aneurysm (rAAA) is a life-threatening condition that carries a high mortality rate. Recent guidelines have recommended a goal "door-to-intervention" time of ≤90 minutes despite a paucity of evidence to support this goal. The aim of this study was to analyze recent trends in door-to-intervention time for rAAAs and determine the effect of the 90-minute door-to-intervention benchmark on postoperative complications. METHODS A retrospective analysis of all patients who underwent open aortic repair (OAR) or endovascular aneurysm repair (EVAR) of a rAAA in the Vascular Quality Initiative database (2003-2018) was performed. Variation in door-to-intervention time was analyzed at the patient and hospital level. Patients were dichotomized into ≤90 or >90 minute door-to-intervention time cohorts. Hierarchical modeling controlling for the hospital random effect and multivariate logistic models was used to analyze the association on 30-day mortality and major in-hospital complications. RESULTS A total of 3,630 operative cases for rAAA were identified (1696 OAR and 1934 EVAR). For the OAR cohort, 1035 patients (61%) had a door-to-intervention time of ≤90 minutes. However, at the hospital level, a minority of hospitals (49%) reliably achieved the OAR goal door-to-intervention time. For OARs, there was no difference in 30-day risk-adjusted major complications or mortality between the ≤90- and > 90-minute cohorts. For EVAR, 1014 patients (53.8%) had a door-to-intervention time of ≤90 minutes and a minority of hospitals (40%) upheld the recommended ≤90 minute door-to-intervention threshold. In the EVAR group, patients with a ≤90 minute door-to-intervention time had higher rates of postoperative myocardial infarction (12.0% vs. 8.5%; P < 0.05) but no difference in 30-day risk-adjusted mortality. CONCLUSIONS A low percentage of rAAAs are being treated within the recommended door-to-intervention time. Despite this deficiency, the ≤90-minute benchmark has minimal impact on postoperative morbidity and mortality. Based on these findings, alternative quality metrics should be identified to improve the clinical care of patients with rAAA.

Abstract
Sweet corn ( L.), a highly consumed fresh vegetable in the United States, varies for tocochromanol (tocopherol and tocotrienol) levels but makes only a limited contribution to daily intake of vitamin E and antioxidants. We performed a genome-wide association study of six tocochromanol compounds and 14 derivative traits across a sweet corn inbred line association panel to identify genes associated with natural variation for tocochromanols and vitamin E in fresh kernels. Concordant with prior studies in mature maize kernels, an association was detected between γ-tocopherol methyltransferase (vte4) and α-tocopherol content, along with () and () for tocotrienol variation. Additionally, two kernel starch synthesis genes, () and (), were associated with tocotrienols, with the strongest evidence for in combination with fixed, strong and alleles, accounting for the greater amount of tocotrienols in and lines. In prediction models with genome-wide markers, predictive abilities were higher for tocotrienols than tocopherols, and these models were superior to those that used marker sets targeting a priori genes involved in the biosynthesis and/or genetic control of tocochromanols. Through this quantitative genetic analysis, we have established a key step for increasing tocochromanols in fresh kernels of sweet corn for human health and nutrition.

Abstract
Unlike many known amphiphiles, the fluorinated amphiphilic dendrimer studied in this work demonstrated a concentration-dependent conformational transition rather than micellization or assembly. Hydrophobic and hydrophilic interactions with water were suggested as the most probable driving force of this transition. This assumption was consistent with the observed 19F chemical shift changes of the dendrimer compared to a known micelle-forming fluorinated amphiphile. Since water is an important factor in the process, trends of the concentration-dependent changes in water proton transverse relaxation rate served as an indicator of structural changes and/or supramolecular assembly. The conformational transition process was also confirmed by ion-mobility mass-spectrometry. We suggested that structural features, namely, steric hindrances, prevented the micellization/assembly of the dendrimer of this study. This conclusion might inform the approach to develop novel unconventional amphiphiles.

Abstract
Balsamia, a hypogeous, sequestrate genus in the Helvellaceae, has been characterized variously as having three to eight species in North America, and these have been considered either different from or conspecific with European species. No available modern systematic treatment of Balsamia exists to allow for accurate identification at the species level. We sequenced DNA from recent western North American Balsamia collections, assessed relationships by sequence similarity, and identified molecular taxonomic units. From these data, we determined which matched descriptions and types of named species. ITS sequences supported 12 Balsamia species in western North America, five originally described by Harkness and Fischer and seven new species that we describe here. No sequences from Balsamia collections in western North America were nested among those of European species. We found no clear evidence for separation of Balsamia into multiple genera.

Abstract
The monotypic genus Phylloporopsis is described as new to science based on Phylloporus boletinoides. This species occurs widely in eastern North America and Central America. It is reported for the first time from a neotropical montane pine woodland in the Dominican Republic. The confirmation of this newly recognised monophyletic genus is supported and molecularly confirmed by phylogenetic inference based on multiple loci (ITS, 28S, TEF1-α, and RPB1). A detailed morphological description of P. boletinoides from the Dominican Republic and Florida (USA) is provided along with colour images of fresh basidiomata in habitat, line drawings of the main anatomical features, transmitted light microscopic images of anatomical features and scanning electron microscope images of basidiospores. The taxonomic placement, ecological requirements and distribution patterns of P. boletinoides are reviewed and the relationships with phylogenetically related or morphologically similar lamellate and boletoid taxa such as Phylloporus, Phylloboletellus, Phyllobolites and Bothia are discussed.

Abstract
INTRODUCTION New persistent opioid use following surgery is a common iatrogenic complication, developing in roughly 6% of patients after elective surgery. Despite increased awareness of misuse and associated morbidity, opioids remain the cornerstone of pain management in bariatric surgery. The potential impact of new persistent opioid use on long-term postoperative outcomes is unknown. We sought to determine the relationship between new persistent opioid use and 1-year postoperative outcomes for patients undergoing bariatric surgery. METHODS Using data from the MBSC registry, we identified patients undergoing primary bariatric surgery between 2006 and 2016. Using previously validated patient-reported survey methodology, we evaluated patient opioid use preoperatively and at 1 year following surgery. New persistent use was defined as a previously opioid-naïve patient who self-reported opioid use 1 year after surgery. We used multivariable logistic regression models to evaluate the association between new persistent opioid use, risk-adjusted weight loss, and psychologic outcomes (psychological wellbeing, body image, and depression). RESULTS 27,799 patients underwent primary bariatric surgery between 2006 and 2016. Among opioid-naïve patients, the rate of new persistent opioid use was 6.3%. At 1-year after surgery, patients with new persistent opioid user lost significantly less excess body weight compared to those without new persistent use (57.6% vs. 60.3%; p < 0.0001). Patients with new persistent opioid use had significantly worse psychological wellbeing (35.0 vs. 33.1; p < 0.0001), body image (19.9 vs. 18.0; p < 0.0001), and depression scores (2.4 vs. 5.0; p < 0.0001). New persistent opioid users also reported less overall satisfaction with their bariatric surgery (75.1% vs. 85.7%; p < 0.0001). CONCLUSIONS New persistent opioid use is common following bariatric surgery and associated with significantly worse physiologic and psychologic outcomes. More effective screening and postoperative surveillance tools are needed to identify these patients, who likely require more aggressive counseling and treatment to maximize the benefits of bariatric surgery.

Abstract
The dopamine transporter (DAT) controls the spatial and temporal dynamics of dopamine neurotransmission through reuptake of extracellular transmitter and is a target for addictive compounds such as cocaine, amphetamine (AMPH), and methamphetamine (METH). Reuptake is regulated by kinase pathways and drug exposure, allowing for fine-tuning of clearance in response to specific conditions, and here we examine the impact of transporter ligands on DAT residue Thr-53, a proline-directed phosphorylation site previously implicated in AMPH-stimulated efflux mechanisms. Our findings show that Thr-53 phosphorylation is stimulated in a transporter-dependent manner by AMPH and METH in model cells and rat striatal synaptosomes, and in striatum of rats given subcutaneous injection of METH. Rotating disc electrode voltammetry revealed that initial rates of uptake and AMPH-induced efflux were elevated in phosphorylation-null T53A DAT relative to WT and charge-substituted T53D DATs, consistent with functions related to charge or polarity. These effects occurred without alterations of surface transporter levels, and mutants also showed reduced cocaine analog binding affinity that was not rescued by Zn2+ Together these findings support a role for Thr-53 phosphorylation in regulation of transporter kinetic properties that could impact DAT responses to amphetamines and cocaine.

Abstract
OBJECTIVES To assess current variation in the management of pinna haematoma (PH) and its effect on outcomes. DESIGN Multicentre retrospective observational record-based study. SETTING Eleven hospitals around the UK. PARTICIPANTS Eighty-three patients above the age of 16 with PH. OUTCOME MEASURES The primary outcome measure was recurrence rate of PH over a 6-month period post-treatment, assessed by treatment type (scalpel incision vs needle aspiration). Secondary outcome measures assessed the impact of other factors on recurrence, infection and cosmetic complications of PH over a period of 6 months. RESULTS After adjusting for confounding factors, involvement of the whole ear, and management within an operating theatre were associated with a lower rate of recurrence of pinna haematoma. The drainage technique, suspected aetiology, choice of post-drainage management, grade and specialty of practitioner performing drainage, the use of antibiotic cover and hospital admission did not affect the rate of haematoma recurrence, infection or cosmetic complications. CONCLUSIONS Where possible PH should be drained in an operating theatre. Multicentre randomized controlled trials are required to further investigate the impact of drainage technique and post-drainage management on outcome.

Abstract
In the summer of 1981, the Research and Degree Committee of the College of Occupational Therapists carried out a survey with the aim of finding out how many occupational therapists had research experience or were interested in becoming involved in research, where they were located and what they considered to be the priorities for research in occupational therapy.

Abstract
This is a case study of a male perpetrator of domestic abuse who voluntarily sought help for abusive behavior toward his partner. The case is described, highlighting a 20-week treatment plan underpinned by an interacting cognitive subsystem-based conceptualization. Evaluation of the therapy is by self-report measures of aggression, assertiveness, and dysfunctional attitude that were administered pre- and posttherapy and at 9-month follow-up. The results are a reduction in aggressive behavior and improved assertiveness, whereas dysfunctional attitudes changed to a profile of greater psychological strengths. Implications for therapeutic intervention and development are also discussed.

Abstract
UNLABELLED This study evaluates the incidence of bone fractures in women with BC.We found that women with invasive breast cancer are at an increased risk for bone fractures, with fractures most commonly occurring at lower extremity and vertebral sites. The risk is further increased in women undergoing cancer therapy. INTRODUCTION Bone loss and fractures in breast cancer have generally been attributed to aromatase inhibitor use. This study assessed the incidence of fractures after invasive breast cancer diagnosis and evaluated bone density and FRAX risk calculation at time of fracture occurrence. METHODS Retrospective cohort study of women with invasive breast cancer [June 2003-December 2011] who participated in an academic hospital based genetic biobank. Demographic and clinical characteristics were abstracted from the electronic medical record (EMR). RESULTS A total of 422 women with invasive breast cancer were assessed; 79 (28 %) sustained fractures during the observation period; fractures occurred at multiple skeletal sites in 27 cases (116 fractures). The incidence of fractures was 40 per 1000 person-years. Women who sustained fractures were mostly white and had a family history of osteoporosis (36.9 %, p = 0.03) or history of a prior fracture (6/79, p = 0.004). Fractures occurred 4.0 years (range 0-12 years) after cancer diagnosis. Fracture cases had femoral neck bone mineral density (BMD) of 0.72 + 0.12 g/cm(2), T-score of -1.2, that is, within the low bone mass range. Fractures most commonly occurred in lower extremities, vertebral, and wrist sites. Hip fractures accounted for 11 % of fractures, occurring at a median age of 61 years. CONCLUSIONS Fractures occur shortly after commencing cancer therapy. Rapid bone loss associated with cancer therapy may precipitate fractures. Fractures occur at relatively higher BMD in BC. Occurrence of fractures in invasive breast cancer raises the possibility of cancer-induced impairment in bone quality.

Abstract
Pre-operative consent discussion and documentation is an essential process that should follow relevant guidance, and include all serious or frequently occurring risks. We assessed the appropriateness of consent for grommet insertion, tonsillectomy, septoplasty, and hemithyroidectomy, by comparing the risks listed in current consenting practice to published complication data for the relevant operation. 120 consent forms and associated clinic letters were analysed. A literature search identified published complication data for comparison. There was great variation in consent practice for each operation type, and poor correlation with published risk incidence. Only 'bleeding' post-tonsillectomy and 'recurrent laryngeal nerve injury' post hemithyroidectomy were listed in 100 % of relevant cases. Common and serious complications were frequently omitted from forms. The number and type of risks consented for a procedure significantly differed between consultant and non-consultant staff. The potential requirement for blood transfusion was discussed in only 20 % of tonsillectomy cases. Currently, the pre-operative consent for commonly performed ENT operations does not reflect operative risks. Consenting for surgical complications should be evidence based using published or personal data. A change in the consent process is required to protect patient autonomy and meet both legal and professional body requirements.

Abstract
The implementation of the European Working Time Regulations (EWTR), coupled with the ongoing impact of Modernising Medical Careers (MMC), has necessitated a significant redevelopment of out-of-hours cover for surgical specialties in the UK. A review of the literature related to the provision of out-of-hours ENT cover gives an insight into the impact of these changes on a comparatively small surgical specialty. A 2008 survey revealed that three-quarters of junior doctors providing ENT out-of-hours care were crosscovering specialties other than ENT – a figure up from just over half of junior doctors in 2005, prior to stricter EWTR rules. Of all 'first-on-call' doctors for ENT, only 19–32% have prior ENT experience. Consequently, ENT services are provided frequently by inexperienced, non-enT doctors covering multiple other specialties, often as part of a 'hospital-at-night' team.

Abstract
Stress activates the hypothalamus-pituitary-adrenal (HPA) axis leading to the release of glucocorticoids (GC). Increased activity of the HPA axis and GC exposure has been suggested to facilitate the development of obesity and metabolic syndrome. Nonetheless, different stressors can produce distinct effects on food intake and may support different directions of food learning e.g. avoidance or acceptance. This study examined whether interoceptive (LiCl and exendin-4) and restraint stress (RS) support similar or distinct food learning. Female rats were exposed to different stressors after their consumption of a palatable food (butter icing). After four palatable food-stress pairings, distinct intakes of the butter icing were observed in rats treated with different stressors. Rats that received butter icing followed by intraperitoneal injections of LiCl (42.3mg/kg) and exendin-4 (10μg/kg) completely avoided the palatable food with subsequent presentations. In contrast, rats experiencing RS paired with the palatable food increased their consumption of butter icing across trials and did so to a greater degree than rats receiving saline injections. These data indicate that interoceptive and psychosocial stressors support conditioned food avoidance and acceptance, respectively. Examination of c-Fos immunoreactivity revealed distinct neural activation by interoceptive and psychosocial stressors that could provide the neural basis underlying opposite direction of food acceptance learning.

Abstract
AIM To investigate the use of anaglyphs and stereograms for three-dimensional imaging of the external nose. METHOD Red-cyan anaglyphs and colour stereograms created from stereo photographs of patients with nasal deformity were compared to standard photographs. Assessors rated images on 'life-likeness' of imaging, contour definition and utility for surgical planning. RESULTS 9 patients were recruited. Stereograms provided significantly improved life-like features and definition of nasal structure, with some benefit for pre-operative planning. Less benefit was found for anaglyph images. Oblique views proved most effective. CONCLUSIONS Stereograms provide simple, inexpensive three-dimensional images of the nose, with potential uses in operative analysis, medicolegal documentation, teaching and research.
