Abstract
PURPOSE To analyze the surgical outcomes of external dacryocystorhinostomy (DCR) and the risk factors associated with functional failure. METHODS We reviewed the medical records of 769 patients who underwent external DCR for primary lacrimal drainage obstruction between 2005 and 2014. Recorded data included intraoperative anatomical findings, postoperative diagnosis, and surgical outcomes. We performed univariate and multivariate analyses to identify risk factors for functional failure. RESULTS Of the 769 cases, primary nasolacrimal duct obstruction (NLDO) was diagnosed in 457 cases; common canalicular obstruction in 228 cases; and canalicular obstruction in 84 cases. Anatomical success was achieved in 98.8% (760/769) and functional success in 81.9% (630/769) of the cases. An analysis of 760 anatomically successful DCRs showed that common canalicular obstruction (OR=1.752, P=0.014) and canalicular obstruction (OR=2.058, P=0.015) were independent risk factors for functional failure. In a subgroup analysis of patients with primary NLDO, patients with a small lacrimal sac had a significantly higher risk of functional failure (OR=2.500, P=0.018). CONCLUSIONS The overall surgical outcomes of external DCR were favorable in this case series. Site of obstruction was an important risk factor for functional failure in cases with primary lacrimal drainage obstruction. A small lacrimal sac was also found to be a risk factor for functional failure in cases with primary NLDO.

Abstract
The farming and agricultural sector remains one of Ireland's primary industries. Fatality rates remain higher than the European average. The aim of this study was to analyze the national trend in hospital in-patient admissions for farmyard related fractures and related fatalities in Ireland from 2005 to 2014. Relevant socioeconomic trends were used for comparison. There were 2,064 farm-related fractures and 187 fatalities recorded over the same period. Despite a decrease in incidence of farmyard fractures over 2005-2014, fatality rates have increased indicating the alarming continued occupational hazards and severity of sustained injuries.

Abstract
We surveyed the attitudes of breast cancer professionals to standard face-to-face and future telemedicine-delivered breast multidisciplinary team (MDT) meetings. Interviews, which included the Group Behaviour Inventory, were conducted face-to-face (n = 19) or by telephone (n = 26). The mean total score on the Group Behaviour Inventory was 96 (SD 19) for 33 respondents, which indicated satisfaction with standard MDT meetings, irrespective of role and base hospital. Positive attitudes to videoconferencing were more common among participants with previous experience of telemedicine (Spearman's rank correlation 0.26, P = 0.91). Common themes emerging from the interviews about telemedicine-delivered MDTs included group leadership, meeting efficiency, group interaction, group atmosphere and technical quality of communication. Most participants were satisfied with standard breast MDTs. Nurses and allied health professionals were least supportive of telemedicine.

Abstract
BACKGROUND European recommendations suggest that medical students should be taught radiation safety before entering clinical practice. AIM The aim of this study was to produce a summative assessment of radiation protection training in medical school in Ireland. MATERIALS AND METHODS A web-based questionnaire was distributed to the 2014 intern population (n = 683) via network intern-coordinators. The survey encompassed knowledge of radiation dose in X-ray investigations, laws governing the prescribing of radiation and complications of radiation exposure to staff and patients. RESULTS Response rate was 14.2% (97/683) with all Irish medical schools represented. 64% of interns reported no formal training in radiation safety. 80% correctly identified MRI and 94% US as not posing a radiation risk. 54% identified CT PET as emitting the highest radiation dose to patients. Only 32% correctly identified one CT abdomen/pelvis as equivalent to the dose from 300 to 500 chest X-rays and 22% correctly identified the theoretical lifetime risk of cancer induction from CT abdomen/pelvis as 1 in 2000. While 71% thought it was very important that prescribers should be aware of patient radiation dose and 28% thought it was moderately important, 74% were not aware of any laws governing the prescribing of radiology investigations. CONCLUSION Currently, there is little formal radiation safety training in Irish medical schools. Knowledge of radiation dose and the laws governing prescribing is limited among qualifying interns. Implementation of a formal radiation safety curriculum in Irish Medical Schools would adhere to EU guidelines and improve prescriber knowledge, patient, and personal radiation safety.

Abstract
INTRODUCTION Peripheral arterial disease (PAD) is being increasingly managed by endovascular therapies. In this study, we identified the clinical services publishing research as well as the journals of publication over a 5-year period. METHODS Twenty keywords and phrases related to endovascular intervention were identified, and a literature search was performed through the PubMed database from January 2009 to January 2014. Inclusion criteria were English language, study population more than five patients, and matching the keyword search. Eligible studies were collated into a database and classified by journal of publication, PubMed number, article title, publishing clinical service, type of publication, country of origin, and authors. RESULTS 825 studies from 114 different journals were identified. 297 papers were excluded. Of the 528 included papers, 204 (39%) were published by Vascular Surgery (VS), 157 (30%) by Interventional Radiology (IR), 101 (19%) by Cardiology, 43 (8%) by Angiology, 6 (1%) by Vascular Medicine, and 17 (3%) from miscellaneous services. 283 (54%) studies originated from Europe, 157 (30%) from North America, 76 (14%) from Asia, 6 from Australia, 3 each from South America and Africa. IR published the most papers on PAD endovascular intervention in Europe with VS second while this trend was reversed in the USA. The 528 papers were published in 98 different journals with retrospective case series (72%), the majority. CONCLUSION IR continues to play a significant research role in endovascular intervention in PAD, particularly in Europe, and specifically in below the knee intervention, pedal intervention, and drug-eluting technologies.

Abstract
A new experiment is described to detect a permanent electric dipole moment of the proton with a sensitivity of 10-29 e ⋅ cm by using polarized "magic" momentum 0.7 GeV/c protons in an all-electric storage ring. Systematic errors relevant to the experiment are discussed and techniques to address them are presented. The measurement is sensitive to new physics beyond the standard model at the scale of 3000 TeV.

Abstract
Venous thromboembolism is a common condition with widely varied outcomes. Pulmonary embolism is associated with a case-fatality rate of up to 8%, increasing up to 18-fold in massive PE. Pharmacological treatment of VTE with anticoagulant medication (AC) is the first line therapy of choice. Retrievable inferior vena cava filters (IVCF) are indicated as a short-term replacement for AC in certain circumstances. Most of the evidence concerning IVCF pertains to permanent filters and older filter models. Limited evidence for retrievable IVCF results in poor consensus regarding indications, follow-up and retrieval. Complications increase with dwell-time and retrieval success rates decline. Professional bodies advocate strict guideline adherence and robust strategies for filter monitoring to maximise retrieval rate.

Abstract
INTRODUCTION Rupture of abdominal aortic aneurysm is a surgical emergency. In order to improve operative outcomes, vascular services have been centralised in the United Kingdom. This means that a patient may present to a hospital with a ruptured aneurysm, but require transfer to a vascular centre for definitive treatment. METHODS This retrospective cohort study identified patients who underwent surgery for ruptured abdominal aortic aneurysm in a tertiary vascular centre over a 2-year period. Data on demographics and originating unit were recorded. Outcomes assessed included 30-day mortality, operative mortality and postoperative morbidity. RESULTS We identified 70 patients who underwent surgery for ruptured abdominal aortic aneurysm in the 2-year period; 36 presented directly to the vascular unit (VU), 14 to referral unit 1 (RU1) and 20 to referral unit 2 (RU2); 30-day mortality rates were 27.7% (VU), 35.5% (RU1) and 30.0% (RU2), respectively. There was no statistical difference in mortality between units. Postoperative complications were seen in 35.9% of VU patients, 78.6% of RU1 patients and 70% of RU2 patients. This was statistically significant between VU and RU1 (P = 0.006) and VU and RU2 (P = 0.02). Direct operative complications were seen in 9 patients, gastrointestinal complications in 9, limb complications in 6 and systemic complications in 40. CONCLUSION This study found that site of presentation does not affect mortality but is associated with increased morbidity. This is a complex issue, which will require a prospective multicentre study to investigate further.

Abstract
The objective of this study was to analyse associations between sexualised substance use (chemsex), STI diagnoses and sexual behaviour among gay bisexual and other men who have sex with men accessing sexual health clinics to better inform clinical pathways. A retrospective case notes review was undertaken following the introduction of more detailed and holistic profomas for all gay bisexual and other men who have sex with men attending two London sexual health clinics between 1 June 2014 and 31 January 2015. Chemsex status was documented for 655/818. Overall, 30% disclosed recreational drug use of whom 113 (57%) disclosed chemsex and 27 (13.5%) injecting drugs. HIV-positive gay bisexual and other men who have sex with men were more likely to disclose chemsex (AOR 6.68; 95% CI 3.91–11.42; p < 0.001). Those disclosing chemsex had a higher incidence of acute bacterial STIs (AOR 2.83 CI 1.79–4.47; p < 0.001), rectal STIs (AOR 3.10 CI 1.81–5.32; p < 0.001) or hepatitis C (AOR 15.41 CI 1.50–158.17; p = 0.021). HIV incidence in the study period was 1.8% (chemsex) vs. 0.9% (no chemsex) (p = 0.61). Chemsex was associated with having more sexual partners, transactional sex, group sex, fisting, sharing sex toys, injecting drug use, higher alcohol consumption and the use of ‘bareback’ sexual networking applications (p < 0.004). Chemsex participants were also more likely to have accessed post-exposure prophylaxis for HIV in the study period and report sex with a discordant HIV or hepatitis C-infected partner (p < 0.001). Chemsex disclosure is associated with higher risk-taking behaviours, acute bacterial STIs, rectal STIs and hepatitis C incidence. HIV incidence was higher but not significantly so in the study period. Chemsex disclosure in sexual health clinics should prompt an opportunity for prevention, health promotion and wellbeing interventions.

Abstract
OBJECTIVES Sexualised substance use, 'chemsex', is being increasingly reported by gay, bisexual and other men who have sex with men (GBMSM) in sexual health clinics. We aim to describe the evidence base and practical ways in which clinicians can assess and advise patients disclosing chemsex. METHODS We review published literature on chemsex, discuss vulnerability to substance use, highlight the importance of clinical communication and discuss a management approach. RESULTS GBMSM are vulnerable to substance use problems, which interplay with mental, physical and sexual health. Knowledge on sexualised drug use and related communication skills are essential to facilitating disclosure. Identifying sexual health and other consequences of harmful drug use may motivate patients to seek change. CONCLUSIONS Sexual health clinicians are well placed to make more holistic assessments of GBMSM accessing their services to promote broader sexual health and well-being beyond the management of HIV and sexually transmitted infections (STIs) alone.

Most Low-Abundance "Background" Symbiodinium spp. Are Transitory and Have Minimal Functional Significance for Symbiotic Corals. MICROBIAL ECOLOGY 2016; 71:771-783.

Abstract
Speculation surrounds the importance of ecologically cryptic Symbiodinium spp. (dinoflagellates) that occur at low abundances in reef-building corals and in the surrounding environment. Evidence acquired from extensive sampling, long-term monitoring, and experimental manipulation can allow us to deduce the ecology and functional significance of these populations and whether they might contribute to the response of coral-dinoflagellate mutualisms to climate change. Quantitative PCR was used here to diagnose the prevalence, seasonal variation, and abundances of Symbiodinium spp. within and between colonies of the coral, Alveopora japonica. Consistent with broader geographic sampling, only one species comprised 99.9 %, or greater, the population of symbionts in every sample. However, other Symbiodinium including the non-mutualistic species, Symbiodinium voratum, were often detected, but at estimated cell densities thousands-fold less than the dominant symbiont. The temporal variation in prevalence and abundances of these "background" Symbiodinium could not be definitively related to any particular environmental factor including seasonality and water chemistry. The prevalence (proportion detected among host samples), but not abundance, of S. voratum may weakly correspond to increases in environmental inorganic silica (SiO2) and possibly nitrogen (NO3). When multiple background Symbiodinium occurred within an individual polyp, the average cell densities were positively correlated, suggesting non-specific processes of cell sorting and retention by the animal. While these findings substantiate the existence of a broader, yet uncharacterized, diversity of Symbiodinium, we conclude that only those species which can occur in high abundance and are temporally stable are ultimately important to coral-dinoflagellate mutualisms. Many transient Symbiodinium spp., which occur only at trace abundances in the coral's microbiome, belong to different functional guilds and likely have little, if any, importance to a coral's physiology. The successful integration between host and symbiont into a stable functional unit should therefore be considered when defining host-symbiont specificity.

Abstract
We report on measurements of the decays of B¯ mesons into the semileptonic final states B¯→D^(*)π^(+)π^(-)ℓ^(-)ν¯, where D^(*) represents a D or D^(*) meson and ℓ^(-) is an electron or a muon. These measurements are based on 471×10^(6) BB ¯ pairs recorded with the BABAR detector at the SLAC asymmetric B factory PEP-II. We determine the branching fraction ratios R_{π^{+}π^{-}}^{(*)}=B(B[over ¯]→D^{(*)}π^{+}π^{-}ℓ^{-}ν[over ¯])/B(B[over ¯]→D^{(*)}ℓ^{-}ν[over ¯]) using events in which the second B meson is fully reconstructed. We find R_{π^{+}π^{-}}=0.067±0.010±0.008 and R_{π^{+}π^{-}}^{*}=0.019±0.005±0.004, where the first uncertainty is statistical and the second is systematic. Based on these results and assuming isospin invariance, we estimate that B[over ¯]→D^{(*)}ππℓ^{-}ν[over ¯] decays, where π denotes either a π^{±} and π^{0} meson, account for up to half the difference between the measured inclusive semileptonic branching fraction to charm hadrons and the corresponding sum of previously measured exclusive branching fractions.

Abstract
BACKGROUND KRAS mutations in NSCLC are associated with a lack of response to epidermal growth factor receptor inhibitors. Selumetinib (AZD6244; ARRY-142886) is an oral selective MEK kinase inhibitor of the Ras/Raf/MEK/ERK pathway. PATIENTS AND METHODS Advanced nonsmall-cell lung cancer (NSCLC) patients failing one to two prior regimens underwent KRAS profiling. KRAS wild-type patients were randomized to erlotinib (150 mg daily) or a combination of selumetinib (150 mg daily) with erlotinib (100 mg daily). KRAS mutant patients were randomized to selumetinib (75 mg b.i.d.) or the combination. The primary end points were progression-free survival (PFS) for the KRAS wild-type cohort and objective response rate (ORR) for the KRAS mutant cohort. Biomarker studies of ERK phosphorylation and immune subsets were carried out. RESULTS From March 2010 to May 2013, 89 patients were screened; 41 KRAS mutant and 38 KRAS wild-type patients were enrolled. Median PFS in the KRAS wild-type arm was 2.4 months [95% confidence interval (CI) 1.3-3.7] for erlotinib alone and 2.1 months (95% CI 1.8-5.1) for the combination. The ORR in the KRAS mutant group was 0% (95% CI 0.0% to 33.6%) for selumetinib alone and 10% (95% CI 2.1% to 26.3%) for the combination. Combination therapy resulted in increased toxicities, requiring dose reductions (56%) and discontinuation (8%). Programmed cell death-1 expression on regulatory T cells (Tregs), Tim-3 on CD8+ T cells and Th17 levels were associated with PFS and overall survival in patients receiving selumetinib. CONCLUSIONS This study failed to show improvement in ORR or PFS with combination therapy of selumetinib and erlotinib over monotherapy in KRAS mutant and KRAS wild-type advanced NSCLC. The association of immune subsets and immune checkpoint receptor expression with selumetinib may warrant further studies.

Abstract
PURPOSE Internal iliac artery (IIA) embolisation is commonly performed prior to endovascular aneurysm repair (EVAR) of aortoiliac aneurysms to prevent type 2 endoleaks via the internal iliac arteries. The safety of this procedure is controversial due to the high incidence of pelvic ischaemic complications. METHODS We undertook a retrospective review of all patients undergoing IIA embolisation before EVAR from 2002 to 2012, to determine incidence of, and factors associated with pelvic ischaemia. RESULTS Eight of 25 patients (32 %) experienced new-onset ischaemia, including erectile dysfunction (4 %), and buttock claudication (28 %) that persisted >6 months in only four patients (16 %). Both bilateral IIA embolisation and a shorter time interval to EVAR correlate with increased risk (p = 0.006 and p = 0.044). No co-morbidities or demographic factors were predictive. CONCLUSIONS We conclude that IIA embolisation remains a beneficial procedure, however, to minimise the risk of buttock claudication we advise against both bilateral IIA embolisation and short time intervals between embolisation and subsequent EVAR.

Abstract
We report a measurement of the time-dependent CP asymmetry of B[over ¯]^{0}→D_{CP}^{(*)}h^{0} decays, where the light neutral hadron h^{0} is a π^{0}, η, or ω meson, and the neutral D meson is reconstructed in the CP eigenstates K^{+}K^{-}, K_{S}^{0}π^{0}, or K_{S}^{0}ω. The measurement is performed combining the final data samples collected at the ϒ(4S) resonance by the BABAR and Belle experiments at the asymmetric-energy B factories PEP-II at SLAC and KEKB at KEK, respectively. The data samples contain (471±3)×10^{6} BB[over ¯] pairs recorded by the BABAR detector and (772±11)×10^{6} BB[over ¯] pairs recorded by the Belle detector. We measure the CP asymmetry parameters -η_{f}S=+0.66±0.10(stat)±0.06(syst) and C=-0.02±0.07(stat)±0.03(syst). These results correspond to the first observation of CP violation in B[over ¯]^{0}→D_{CP}^{(*)}h^{0} decays. The hypothesis of no mixing-induced CP violation is excluded in these decays at the level of 5.4 standard deviations.

Abstract
Saccharomyces cerevisiae, an ascosporogenous yeast commonly used in the production of food, is an emerging infection in immunocompromised patients. We report the case of a 60-year-old man whose orthotopic liver transplant was complicated by S. cerevisiae fungemia and peritoneal abscess, successfully treated with caspofungin and drainage. We also review the literature of invasive saccharomycoses in recipients of hematologic and solid organ transplants.

Abstract
CIRSE established a registry of retrievable filter use with the primary aim of determining the success of IVC Filter retrieval and associated complications. Secondary endpoints included filter indications, imaging strategies before retrieval, filter dwell times, and anticoagulation status. A web-based electronic registry was hosted between 01/12/2010 and 30/06/2012. Data entry occurred at the date of IVC filter retrieval and included items such as filter type, indication for filter insertion, access route, dwell time, retrieval success, complications, reasons for failed retrieval, and anticoagulation status. 671 filter retrievals were entered (male:female 333:295, mean age 55, median 57). Retrieval data were not entered in 43/671 leaving 628 patients for analysis. The 4 commonest retrievable filters used were the Celect in 182 patients, the OPTEASE in 161, ALN in 120, and Gunther Tulip in 98. Filters were inserted for absolute indications 40%, relative indications in 31%, and prophylactic in 24%, with 5% missing. Mean filter dwell time was 90 days. Filters were successfully retrieved in 576/628 patients (92%). The mean dwell time for successful retrievals was 85 days versus 145 days for unsuccessful retrievals (p = 0.001). Major complications occurred in 2 patients (0.03%). In summary, the CIRSE retrievable filter registry demonstrates a retrieval rate of 92% across a range of filter types, with a low major complication rate, reflecting current practice. There is an increase in trend of retrievable filter use for relative and prophylactic indications.

Abstract
We present a search for a neutral, long-lived particle L that is produced in e+ e- collisions and decays at a significant distance from the e+ e- interaction point into various flavor combinations of two oppositely charged tracks. The analysis uses an e+ e- data sample with a luminosity of 489.1 fb(-1) collected by the BABAR detector at the ϒ(4S), ϒ(3S), and ϒ(2S) resonances and just below the ϒ(4S). Fitting the two-track mass distribution in search of a signal peak, we do not observe a significant signal, and set 90% confidence level upper limits on the product of the L production cross section, branching fraction, and reconstruction efficiency for six possible two-body L decay modes as a function of the L mass. The efficiency is given for each final state as a function of the mass, lifetime, and transverse momentum of the candidate, allowing application of the upper limits to any production model. In addition, upper limits are provided on the branching fraction B(B→XsL), where Xs is a strange hadronic system.

Abstract
BACKGROUNDS Leukoaraiosis may present with slowly progressive parkinsonism indistinguishable from primary degenerative parkinsonism. Both leukoaraiosis and degenerative parkinsonism are an age-related disorder. Thus, comorbidity is expected to be common in elderly patients with parkinsonism. However, no systematic study has been reported on the clinical features indicating concomitant nigrostriatal dopaminergic denervation (NDD) in parkinsonian patients with leukoaraiosis. METHODS We performed [(18)F] FP-CIT positron emission tomography studies in 42 consecutive parkinsonian patients with diffuse leukoaraiosis, but no basal ganglia vascular lesions. RESULTS Twenty (48%) of the 42 patients had coexisting NDD. Compared to parkinsonian patients with isolated leukoaraiosis, those with coexisting NDD more frequently had asymmetric onset. They had similar degree of parkinsonian motor deficits in the legs, but greater rigidity and resting tremor in the arms. Consequently, they had less prominent lower body parkinsonism. They more frequently showed favorable response to levodopa treatment. They had similar burden of regional and total leukoaraiosis. Among a variety of clinical variables and MRI findings, only asymmetric onset and more than 30% improvement in UPDRS motor score by levodopa treatment were valuable indicators of coexisting NDD. CONCLUSIONS We would like to recommend dopaminergic functional imaging studies for all parkinsonian patients with leukoaraiosis. Further studies are needed to confirm sensitivity and specificity of asymmetric onset and good levodopa response for the prediction of coexisting NDD in a different group of parkinsonian patients with leukoaraiosis.

Abstract
The papaya (Carica papaya L.) is one of the most important economic tropical fruits in the world, and the hermaphrodite is the preferred type in field cultures. We analyzed the sexual ratio of offspring from the cultivar 'Taiwan Seed Station No. 7' (T7) by a self-cross and its cross with Taichung Sunrise (TS). Female progeny from the T7 self-crossing were not observed. This finding may be caused by a lethal gene that is linked to females. In this study, we selected 192 simple sequence repeats (SSRs) to analyze the polymorphism between T7 and TS. A total of 37 SSRs were identified for T7 and TS. In addition, 14 SSRs served as the molecular makers for identification of T7, TS and their hybrid offsprings. Thus, the results show that the genetic similarity between T7 and TS is rather high. This suggests that T7 may be a mutant of TS. Phylogenetic analysis from the SSR polymorphisms of the above parent strains and 15 F1 offspring revealed the genetic distance of the F1 offspring located between T7 and TS. The results of this study may provide an opportunity for elucidating the genetic characteristics of all hermaphrodites via identification of molecular makers.

Abstract
We present a measurement of the asymmetry A_{CP} between same-sign inclusive dilepton samples ℓ^{+}ℓ^{+} and ℓ^{-}ℓ^{-} (ℓ=e, μ) from semileptonic B decays in ϒ(4S)→BB[over ¯] events, using the complete data set recorded by the BABAR experiment near the ϒ(4S) resonance, corresponding to 471×10^{6} BB[over ¯] pairs. The asymmetry A_{CP} allows comparison between the mixing probabilities P(B[over ¯]^{0}→B^{0}) and P(B^{0}→B[over ¯]^{0}), and therefore probes CP and T violation. The result, A_{CP}=[-3.9±3.5(stat)±1.9(syst)]×10^{-3}, is consistent with the standard model expectation.

Abstract
This work was conducted to investigate the performance and meat characteristics of commercial Korean native duck (KND). A total of 180 1-d-old ducklings of 2-way crossbreds from A and B lines (from National Institute of Animal Science) were used in this work and divided into 4 groups (3 replicates/group, 15 birds/replicate). The four groups were 4 crossbreds as AA (A line [♀]×A line [♂]), AB (A line [♀]×B line [♂]), BB (Pure line B strains) and BA (B strains [♀]×A strain [♂]). Ducks were fed diets based on corn-soybean meal for 0 to 3 wk (22.4% crude protein [CP], 2,945 kcal/kg metabolizable energy [ME]) and 3 to 8 wk (18.4% CP, 3,047 kcal/kg ME). As a result of this study, average body weight of 4 crossbreds were 625, 1,617, 2,466, and 2,836 g at 2, 4, 6, and 8 weeks, respectively, and significantly increased over the period of time (p<0.05). Body weight of BB group was greater than other crossbreds at the age of 6 weeks (p<0.05). There was a significant difference in weekly body weight gains (p<0.05), which were 573, 991, 850, and 371 g at 2, 4, 6, and 8 weeks old, respectively. Uniformity of 4 crossbreds was 84.9%, 80.5%, and 72.5% at 6, 7, and 8 weeks, respectively, and there was no difference among crossbreds. Body weight gain of BB crossbred was highest among crossbreds (p<0.05). Weekly feed intake significantly increased with weeks as 669, 1,839, 2,812, and 3,381 g at 2, 4, 6, and 8 weeks respectively (p<0.05). Feed intakes of AA and BB crossbreds were higher at 2 to 4 weeks old than others and that of BB crossbred was highest at 4 to 6 weeks old (p<0.05). Weekly feed conversion ratios were 1.17, 1.86, 3.32, and 9.37 at 0 to 2, 2 to 4, 4 to 6, and 6 to 8 weeks old, respectively, and it increased with age (p<0.05). There was no significant difference in feed conversion ratio among crossbreds. Carcass yields of 4 crossbreds were 73.6%, 71.6%, 73.5%, and 71.7%, respectively, so there was no significant difference among crossbreds. There was no difference in wing, neck, breast and leg ratios among crossbreds. However, back ratios of 4 crossbreds were 17.6%, 18.0%, 15.8%, and 17.6%, respectively, and back ratio of BB was the highest among crossbreds. Finally, these results may provide the basic data on the production, carcass quality, fatty acid and amino acid composition of commercial KND with 2-way crossbreeding.

Abstract
BACKGROUND Palliative management of malignant pancreaticobiliary (PB) disease typically takes the form of endoscopic biliary stenting with a covered metal stent. We set out to assess outcomes from endoscopic biliary stenting (endoscopic retrograde cholangiopancreatography, ERCP) for malignant disease in our district general hospital (DGH). METHODS We identified patients with malignant PB disease who underwent primary ERCP between 2011 and 2012. Case notes were reviewed for clinical outcomes and involvement of palliative care. RESULTS 38 patients underwent biliary stenting in this period. Median age was 75.6 years (53.6-99.8 years). 35 stents were placed for primary PB malignancy. 31 of these stents were covered metal stents and 6 were uncovered. Bilirubin decreased from a median of 218 to 112 µmol/L (median decrease 55 µmol/L). Complications occurred in the following 13 cases: 7 blocked stents (18.9%), 2 of which were associated with sepsis; 2 cases of stent migration (8.1%); 3 cases of biliary sepsis (8.1%) and 1 episode of pancreatitis (2.7%). Subsequently, 12 patients underwent a single repeat ERCP and 1 patient underwent 3 further ERCPs. Median survival following ERCP and stent was 78 days (10-806). 28 patients (76%) were known to the hospital palliative care team. CONCLUSIONS Our DGH provides local service with complication rates comparable to those described in the literature. This allows care of patients with limited prognosis to be treated close to home. The majority of stent complications and mortality occur within 3 months. Input from the palliative care team is useful when considering whether a patient has a prognosis long enough to benefit from the procedure.

Abstract
Dark sectors charged under a new Abelian interaction have recently received much attention in the context of dark matter models. These models introduce a light new mediator, the so-called dark photon (A^{'}), connecting the dark sector to the standard model. We present a search for a dark photon in the reaction e^{+}e^{-}→γA^{'}, A^{'}→e^{+}e^{-}, μ^{+}μ^{-} using 514 fb^{-1} of data collected with the BABAR detector. We observe no statistically significant deviations from the standard model predictions, and we set 90% confidence level upper limits on the mixing strength between the photon and dark photon at the level of 10^{-4}-10^{-3} for dark photon masses in the range 0.02-10.2 GeV. We further constrain the range of the parameter space favored by interpretations of the discrepancy between the calculated and measured anomalous magnetic moment of the muon.
