Abstract
Pesticide exposure is an important driver of bee declines. Laboratory toxicity tests provide baseline information on the potential effects of pesticides on bees, but current risk assessment schemes rely on one species, the highly social honey bee, Apis mellifera, and there is uncertainty regarding the extent to which this species is a suitable surrogate for other pollinators. For this reason, Osmia cornuta and Osmia bicornis have been proposed as model solitary bee species in the EU risk assessment scheme. The use of solitary bees in risk assessment requires the development of new methodologies adjusted to the biology of these species. For example, oral dosing methods used with honey bees cannot be readily applied to solitary bees due to differences in feeding behaviour and social interactions. In this study, we describe the "petal method", a laboratory feeding method, and validate its use in acute and chronic exposure oral tests with Osmia spp. We conducted five experiments in which we compared the performance of several artificial flowers combining visual and olfactory cues against the petal method, or in which variations of the petal method were confronted. We then use the results of these experiments to optimize the feeding arenas and propose standardized methods for both acute and chronic exposure tests. The petal method provides high levels of feeding success, thus reducing the number of bees needed. It works with a wide variety of petal species and with both female and male Osmia spp., thus ensuring reproducibility across studies. To validate the use of the petal method in ecotoxicology tests, we assess the toxicity of a standard reference insecticide, dimethoate, in O. cornuta adults and determine LD50 values for this species. The petal method should facilitate the inclusion of solitary bees in risk assessment schemes therefore increasing the protection coverage of pesticide regulation.

Abstract
The diet of a potentially omnivorous coastal shark species, the bonnethead (Sphyrna tiburo), was examined in the western Atlantic along the coast of the southeastern United States. A total of 423 stomachs collected from Texas, Alabama, Florida and South Carolina were analyzed using standardized stomach content analysis methods. The diet was dominated by crabs, primarily portunids (Callinectes spp.), across the geographical range analyzed, though the relative importance of crabs varied between regions. Ontogenetic shifts in diet were not observed throughout the region studied. Female and male bonnetheads in South Carolina displayed different diets, particularly in the amount of portunid crabs consumed, with a higher proportion ingested by females. Bonnetheads consumed limited amounts of seagrasses in all regions except in South Carolina, where they occupy habitats without seagrasses in marsh dominated bays and estuaries. This finding indicates that, at least seasonally, seagrasses are not an essential part of the diet of this shark species and may only occur in stomachs as accidental ingestion.

Abstract
AIMS Moderately hypofractionated breast irradiation has been evaluated in several prospective studies, resulting in wide acceptance of shorter treatment protocols for postoperative breast irradiation. Reimbursement for radiation therapy varies between private and public systems and between countries, impacting variably financial considerations in the use of hypofractionation. The aim of this study was to evaluate the financial impact of moderately hypofractionated breast irradiation by reimbursement system in different countries. MATERIALS AND METHODS The study was designed by an international group of radiation oncologists. A web-questionnaire was distributed to representatives from each country. The participants were asked to involve the financial consultant at their institution. RESULTS Data from 13 countries from all populated continents were collected (Europe: Denmark, France, Italy, the Netherlands, Spain, UK; North America: Canada, USA; South America: Brazil; Africa: South Africa; Oceania: Australia; Asia: Israel, Taiwan). Clinicians and/or departments in most of the countries surveyed (77%) receive remuneration based on the number of fractions delivered to the patient. The financial loss per patient estimated resulting from applying moderately hypofractionated breast irradiation instead of conventional fractionation ranged from 5-10% to 30-40%, depending on the healthcare provider. CONCLUSION Although a generalised adoption of moderately hypofractionated breast irradiation would allow for a considerable reduction in social and economic burden, the financial loss for the healthcare providers induced by fee-for-service remuneration may be a factor in the slow uptake of these regimens. Therefore, fee-for-service reimbursement may not be preferable for radiation oncology. We propose that an alternative system of remuneration, such as bundled payments based on stage and diagnosis, may provide more value for all stakeholders.

Abstract
Radiotherapy is a treatment with curative intent, both in patients with primary diagnosis of prostate cancer (PCa) and in patients presenting with biochemical recurrence after radical prostatectomy (RP). Moreover, the use of stereotactic body radiotherapy as a metastasis directed therapy in patients with oligometastatic PCa has significantly increased in the recent years. Conventional imaging techniques, including transrectal ultrasound, computed tomography (CT), morphologic magnetic resonance and bone scintigraphy have traditionally played a minor role in all those clinical scenarios due to its low diagnostic accuracy. The recent development of the positron emission tomography (PET) radiotracer 68Ga-PSMA binding to the prostate specific membrane antigen (PSMA), a transmembrane glycoprotein overexpressed in PCa cells, has shown promising results. Detection rates for PCa lesions are higher than CT and higher than the best technique available, the PET/CT with choline. Its superiority has been demonstrated even at very low PSA levels (<1 ng/ml). This increase in diagnostic accuracy represents a potential impact on patient management, especially in radiotherapy. Even if this imaging technique is already available for routine clinical practice in some European countries, in Spain, unfortunately, there is very limited access. In this review, we analyze the main studies that investigate the usefulness of 68Ga-PSMA PET/CT in patients with PCa and its potential impact on radiotherapy treatments. In addition, we compared the 68Ga-PSMA PET/CT, with the multiparametric magnetic resonance imaging and the PET/CT with choline, in the different clinical scenarios.

Abstract
PURPOSE To investigate patterns of practice among Spanish radiation oncologists in the use of multiparametric magnetic resonance imaging (mpMRI) for the treatment of prostate cancer (PCa). We evaluated (1) access to mpMRI, (2) current clinical practices, and (3) physician expectations of mpMRI. METHODS Cross-sectional survey of 118 radiation oncologists at 75 Radiation Oncology (RO) departments in Spain. RESULTS A total of 55 radiation oncologists from 52 RO departments (52/75; 69%) completed the survey. Prostate mpMRI is performed at 94.5% of the centres that provided data. The most common indications for mpMRI in routine clinical practice were: (1) detection/localization of the tumour prior to second biopsy (82.7%), (2) cancer staging (80.8%), and (3) detection of recurrence after definitive treatment (80.8%). Most respondents (72.7%) reported modifying the primary radiotherapy treatment when mpMRI findings indicate a more advanced T stage with a resultant change in the risk group. Most respondents (90.5%) treat macroscopic local recurrence after prostatectomy with high doses, ranging from 71 to 83 Gy; in 37.7% of cases, the full dose is delivered to the entire prostate bed. In pelvic nodal recurrence, more than half (59.3%) of the respondents reported performing elective pelvic radiotherapy, including the prostate bed, with a boost to the involved nodes. CONCLUSIONS This survey shows that prostate mpMRI is routinely used by radiation oncologists in Spain in a wide range of clinical scenarios. The findings reported here underscore the need to standardize treatment protocols for definitive and salvage radiotherapy in patients evaluated with mpMRI.

Abstract
PURPOSE/OBJECTIVE Little is known about the clinical impact of using multiparametric MRI to plan early salvage radiotherapy after radical prostatectomy. We aimed to evaluate the incidence and location of recurrence based on pelvic multiparametric MRI findings and to identify clinical variables predictive of positive imaging results. MATERIALS AND METHODS We defined radiological criteria of local and lymph node malignancy and reviewed records and MRI studies of 70 patients with PSA recurrence after radical prostatectomy. We performed univariate and multivariate analysis to identify any association between clinical, pathological and treatment-related variables and imaging results. RESULTS Multiparametric MRI was positive in 33/70 patients. We found local and lymph node recurrence in 27 patients and 7 patients, respectively, with a median PSA value of 0.38 ng/ml. We found no statistically significant differences between patients with positive and negative multiparametric MRI for any variable. Shorter PSADT was associated with positive lymph nodes (median PSADT: 5.12 vs 12.70 months; p: 0.017). CONCLUSIONS Nearly half the patients had visible disease in multiparametric MRI despite low PSA. Positive lymph nodes incidence should be considered when planning salvage radiotherapy, particularly in patients with a short PSADT.

Abstract
Prolonged and high-speed swimming performance measurements were used to explore the swimming abilities of two species of estuarine fishes, the mummichog Fundulus heteroclitus and the striped killifish Fundulus majalis, under different salinities. Critical swimming performance was significantly higher for F. majalis in high salinity than in low salinity, but no difference was observed in brief constant acceleration swimming trials in this species; however, the swimming performance of F. heteroclitus was not significantly affected by salinity changes, indicating that this species is well adapted to regular estuarine salinity oscillations. Fundulus majalis displayed higher swimming speeds than F. heteroclitus in both high and low salinities, and while this cannot be explained by their respective salinity preferences, the specific habitat preferences of F. majalis for sandy subtidal habitats and F. heteroclitus for vegetated marshes could explain the better swimming performance of F. majalis.

Abstract
AIM The purpose of the study was to describe infrastructures, treatment modalities, and workload in radiation oncology (RO) in Spain, referred particularly to prostate cancer (PC). METHODS An epidemiologic, cross-sectional study was performed during 2008-2009. A study-specific questionnaire was sent to the 108 RO-registered departments. RESULTS One hundred and two departments answered the survey, and six were contacted by telephone. Centers operated 236 treatment units: 23 (9.7 %) cobalt machines, 37 (15.7 %) mono-energetic linear accelerators, and 176 (74.6 %) multi-energy linear accelerators. Sixty-one (56.4 %) and 33 (30.5 %) departments, respectively, reported intensity-modulated radiation therapy (IMRT) and image-guided RT (IGRT) capabilities; three-dimensional-conformal RT was used in 75.8 % of patients. Virtual simulators were present in 95 departments (88.0 %), 35 use conventional simulators. Fifty-one departments (47.2 %) have brachytherapy units, 38 (35.2 %) perform prostatic implants. Departments saw a mean of 24.9 new patients/week; the number of patients treated annually was 102,054, corresponding to 88.4 % of patients with a RT indication. In 56.5 % of the hospitals, multidisciplinary teams were available to treat PC. CONCLUSIONS Results provide an accurate picture of current situation of RO in Spain, showing a trend toward the progressive introduction of new technologies (IMRT, IGRT, brachytherapy).

Abstract
Several species of fish, aggregate around DFADs in marine tropical waters. We captured three predatory species: yellow fin tuna (Thunnus albacares), wahoo (Acanthocybium solandri) and dolphinfish (Coryphaena hippurus) from aggregations under DFADs in the Western Indian Ocean to characterize their diet and determine whether they fed on other DFAD associated organisms. Yellowfin tuna did not feed on DFAD–associated prey, while wahoo and dolphinfish did exploit resources aggregated by the DFADs, though they predominantly fed on other non–associated organisms. Opportunistic feeding on surface swarming stomatopod crustaceans was observed in yellowfin tuna and dolphinfish associated with FADs, but was not observed in wahoo.

Abstract
PURPOSE To evaluate retrospectively the cumulative risk probability and factors correlated with renal dysfunction after allogeneic bone marrow transplantation (BMT). PATIENTS AND METHODS From October 1984 to July 1994, 84 patients with malignant hematopoietic diseases received allogeneic BMT after conditioning with high-dose chemotherapy and total-body irradiation (TBI). Seventy-nine patients with normal renal function before conditioning are included in this study. Conditioning included high-dose cyclophosphamide without (n = 46) or with (n = 33) other agents (daunorubicin, busulfan, cytarabine, and thiotepa) followed by TBI. The TBI dose prescribed to the center of the abdomen was 10 Gy for 24 patients, 12 Gy for 32, and 13.5 Gy for 23. In vitro T-cell depletion was undertaken in 48 cases. The post-BMT nephrotoxicity of aminoglycosides, vancomycin, amphotericin, and cyclosporine was assessed. Time to renal dysfunction was defined as the time to a persistent increase of serum creatinine (SCr) level greater than 110 mumol/L. The potential influence of sex, age, diagnosis, chimerism, and graft-versus-host disease (GvHD) on renal dysfunction was also assessed. RESULTS The 18-month probability of renal dysfunction-free survival (RDFS) for the whole group was 77%. Only TBI dose and presence of GvHD were significantly correlated with renal dysfunction by multivariate analysis. The 18-month probabilities of RDFS were 95%, 74%, and 55% for the patients conditioned with 10, 12, and 13.5 Gy, respectively. The 18-month RDFS probabilities were 88% and 61% for patients without and with GvHD, respectively. Combining both variables, we have defined two risk categories: low-risk (ie, 10 Gy TBI with/without GvHD and 12 Gy TBI without GvHD) and high-risk (ie, 12 Gy TBI with GvHD and 13.5 Gy TBI with/without GvHD). The predicted 18-month RDFS rates were 93% and 52% for the low- and high-risk groups, respectively. CONCLUSION Renal dysfunction after allogeneic BMT is strongly related to the delivered TBI dose (and dose per fraction) and to the presence of GvHD. Renal shielding should be recommended if a TBI dose greater than 12 Gy (fractionated twice daily over 3 days) is to be prescribed. Furthermore, in those cases with a high risk of developing GvHD (eg, unrelated allogeneic BMT, absence of T-cell depletion), these data suggest that kidney doses greater than 10 Gy should be avoided.

Abstract
The incidence of malignant disease appears to be increased in patients with dermatomyositis, although the relationship between dermatomyositis and cancer is still controversial. The most frequently associated tumors are not different from the tumors observed in the general population. There are very few cases of head and neck cancer associated with myositis reported in the medical literature despite the high incidence of these tumors in western countries. Two new cases are reported and the relationship between myositis and cancer is discussed.

Abstract
Eleven entire and twelve castrated male pigs were implanted with trenbolone acetate and the effects of the treatment on genital tract macro- and microscopical modifications were evaluated and compared to non-implanted animals. In entire male pigs a reduction of testicular weight and size was observed as a consequence of the treatment (< 0.001), but no important modifications were found in bulbourethral gland and seminal vesicles macroscopically. Castrated non-implanted males had bulbourethral gland atrophy (P < 0.01), while castrated implanted ones showed similar development to entire males. As for vesicular glands there were no significant differences among the four groups under study. Histological study of prostate has demonstrated structural modifications. As a consequence of the treatment glandular lumen was increased (P < 0.05), and most parenchyma was occupied by polymorphous cysts.

Abstract
Twenty-four gilts and 24 barrows were divided into two groups of 12 of each gender. One group was implanted with 300 mg of trenbolone acetate, and the other one was used as a control. Treatment had no effect on fat thickness in gilts but significantly reduced fatness in barrows. The fatty acid composition of the backfat showed a tendency toward greater unsaturation in treated barrows. Key words: Pig, trenbolone acetate, anabolic
