On the spread of the European catfish (Silurus glanis) in the Iberian Peninsula: first record in the Llobregat river basin

The first record of the European catfish (Silurus glanis L. 1758) introduced to the Llobregat river basin (NE Spain) is reported. We captured one individual of this silurid fish species (of a total of 541 fish) in La Baells reservoir on 30 August 2006. Given the low catchability of this fish species, the popularity among some anglers, and old rumours on this introduction, we hypothesize that this species has been present in the reservoir since a few years ago, despite we did not capture it in two previous surveys. The illegal introduction of this and other exotic species to other Iberian river basins should be prevented by the Spanish administration

Prediction of functional outcome 18 months after a first psychotic episode: a proton magnetic resonance spectroscopy study.

CONTEXT: Recent magnetic resonance imaging studies have attempted to relate volumetric brain measurements in early schizophrenia to clinical and functional outcome some years later. These studies have generally been negative, perhaps because gray and white matter volumes inaccurately assess the underlying dysfunction that might be predictive of outcome. OBJECTIVE: To investigate the predictive value of frontal and temporal spectroscopy measures for outcome in patients with first-episode psychoses. DESIGN: Left prefrontal cortex and left mediotemporal lobe voxels were assessed using proton magnetic resonance spectroscopy to provide the ratio of N-acetylaspartate (NAA) and choline-containing compounds to creatine and phosphocreatine (Cr) (NAA/Cr ratio). These data were used to predict outcome at 18 months after admission, as assessed by a systematic medical record audit. SETTING: Early psychosis clinic. PARTICIPANTS: Forty-six patients with first-episode psychosis. MAIN OUTCOME MEASURES: We used regression models that included age at imaging and duration of untreated psychosis to predict outcome scores on the Global Assessment of Functioning Scale, Clinical Global Impression scales, and Social and Occupational Functional Assessment Scale, as well as the number of admissions during the treatment period. We then further considered the contributions of premorbid function and baseline level of negative symptoms. RESULTS: The only spectroscopic predictor of outcome was the NAA/Cr ratio in the prefrontal cortex. Low scores on this variable were related to poorer outcome on all measures. In addition, the frontal NAA/Cr ratio explained 17% to 30% of the variance in outcome. CONCLUSIONS: Prefrontal neuronal dysfunction is an inconsistent feature of early psychosis; rather, it is an early marker of poor prognosis across the first years of illness. The extent to which this can be used to guide treatment and whether it predicts outcome some years after first presentation are questions for further research.

Mise au point et validation d'un fantôme spécifique pour asssurer le suivi des mesures quantitatives en tomographie par émission de positons.

L'index de consommation du glucose, SUV pour standardized uptake value, est largement utilisé en tomographie par émission de positons (TEP) pour quantifier la concentration relative de [18F]2-fluoro-2-désoxy-D-glucose (18F-FDG) dans les tissus. Cependant, cet indice dépend de nombreux facteurs méthodologiques et biologiques et son utilisation fait débat. Il est donc primordial d'instaurer un contrôle qualité régulier permettant d'assurer la stabilité de la mesure des indices quantitatifs. Dans cette optique, un fantôme spécifique avec inserts cylindriques de différentes tailles a été développé. L'objectif de cette étude est de montrer la sensibilité et l'intérêt de ce fantôme. Méthodes. - La sensibilité du fantôme a été étudiée à travers la mesure des SUV et des coefficients de recouvrement (RC). Plusieurs méthodes de mesure ont été utilisées. Les données ont été reconstruites en utilisant les algorithmes de routine clinique. Nous avons étudié la variation des RC en fonction de la taille des cylindres et le changement relatif de fixation, en utilisant des activités différentes. Le fantôme a ensuite été testé sur l'appareil d'un autre centre. Résultats. - Pour toutes les méthodes de mesure, une forte variation des RC avec la taille des cylindres, de l'ordre de 50 %, a été obtenue. Ce fantôme a également permis de mesurer un changement relatif de fixation qui s'est révélé être indépendant de la méthode de mesure. Malgré un étalonnage des deux systèmes TEP/TDM, des différences de quantification d'environ 20 % ont subsisté. Conclusion. - Les résultats obtenus montrent l'intérêt de ce fantôme dans le cadre du suivi des mesures quantitatives.

Hypatropis inermis (Hemiptera, Pentatomidae): first record on rice crops

This study reports for the first time the occurrence of Hypatropis inermis on upland rice crops (variety Cambará), in Novo Progresso, state of Pará, Brazil (7°07'45.71"S 55°23'21.13"W). The inventory of insect pests was conducted between November 2010 and March 2011 with entomological sweep nets and visual search on stems of rice plants. This record indicates that rice crops may represent important feeding and mating sites for this species.

First record of Molorchus minor minor (Linnaeus) (Coleoptera, Cerambycidae) in Brazil

Molorchus minor minor (Linnaeus) (Coleoptera, Cerambycidae) is recorded for the first time in Brazil (Bahia). It was originally described from Europe and is currently widely distributed in that continent and Asia.

First record of folivory on a newly documented host plant for the little known geometrid moth Eupithecia yubitzae Vargas & Parra (Lepidoptera, Geometridae) in northern Chile

The native tree Schinus molle (Anacardiacae) is reported for the first time as a host plant for larvae of the little known geometrid moth Eupithecia yubitzae Vargas & Parra (Lepidoptera, Geometridae) in the Atacama Desert of northern Chile, based on morphology and DNA barcodes. This discovery importantly expands the host range of E. yubitzae, as previous records were restricted to Fabaceae trees. Larvae were previously known as florivorous, while these were found to be folivorous on S. molle. Furthermore, host-associated cryptic larval polychromatism was detected, as larvae collected on S. molle were found to be mostly pale green, contrasting with the dark yellow ground color of the larvae typically collected on fabaceous host plants.

Effects of the playing surface on plantar pressures during the first serve in tennis.

PURPOSE: This study aimed at examining the influence of different playing surfaces on in-shoe loading patterns in each foot (back and front) separately during the first serve in tennis. METHODS: Ten competitive tennis players completed randomly five first (ie, flat) serves on two different playing surfaces: clay vs GreenSet. Maximum and mean force, peak and mean pressure, mean area, contact area and relative load were recorded by Pedar insoles divided into 9 areas for analysis. RESULTS: Mean pressure was significantly lower (123 ± 30 vs 98 ± 26 kPa; -18.5%; P < .05) on clay than on GreenSet when examining the entire back foot. GreenSet induced higher mean pressures under the medial forefoot, lateral forefoot and hallux of the back foot (+9.9%, +3.5% and +15.9%, respectively; both P < .01) in conjunction with a trend toward higher maximal forces in the back hallux (+15.1%, P = .08). Peak pressures recorded under the central and lateral forefoot (+21.8% and +25.1%; P < .05) of the front foot but also the mean area values measured on the back medial and lateral midfoot were higher (P < .05) on clay. No significant interaction between foot region and playing surface on relative load was found. CONCLUSIONS: It is suggested that in-shoe loading parameters characterizing the first serve in tennis are adjusted according to the ground type surface. A lesser asymmetry in peak (P < .01) and mean (P < .001) pressures between the two feet was found on clay, suggesting a greater need for stability on this surface.

Predictive value of the MGMT promoter methylation status in metastatic melanoma patients receiving first-line temozolomide plus bevacizumab in the trial SAKK 50/07.

The O6-methylguanine-DNA-methyltransferase (MGMT) promoter methylation status is a predictive parameter for the response of malignant gliomas to alkylating agents such as temozolomide. First clinical trials with temozolomide plus bevacizumab therapy in metastatic melanoma patients are ongoing, although the predictive value of the MGMT promoter methylation status in this setting remains unclear. We assessed MGMT promoter methylation in formalin-fixed, primary tumor tissue of metastatic melanoma patients treated with first-line temozolomide and bevacizumab from the trial SAKK 50/07 by methylation-specific polymerase chain reaction. In addition, the MGMT expression levels were also analyzed by MGMT immunohistochemistry. Eleven of 42 primary melanomas (26%) revealed a methylated MGMT promoter. Promoter methylation was significantly associated with response rates CR + PR versus SD + PD according to RECIST (response evaluation criteria in solid tumors) (p<0.05) with a trend to prolonged median progression-free survival (8.1 versus 3.4 months, p>0.05). Immunohistochemically different protein expression patterns with heterogeneous and homogeneous nuclear MGMT expression were identified. Negative MGMT expression levels were associated with overall disease stabilization CR+PR+SD versus PD (p=0.05). There was only a poor correlation between MGMT methylation and lack of MGMT expression. A significant proportion of melanomas have a methylated MGMT promoter. The MGMT promoter methylation status may be a promising predictive marker for temozolomide therapy in metastatic melanoma patients. Larger sample sizes may help to validate significant differences in survival type endpoints.

Six Years of Denosumab Treatment in Postmenopausal Women with Osteoporosis: Results From the First Three Years of the FREEDOM Extension

Background/Purpose: Denosumab (DMAb) is an approved therapy for the treatment of postmenopausal women with osteoporosis at increased risk for fracture. A favorable risk/benefit profile was demonstrated in the pivotal, 3-year FREEDOM trial (Cummings et al NEJM 2009). The open-label, active-treatment FREEDOM Extension study is investigating the efficacy and safety of DMAb for up to 10 years. The Extension trial enrolled women who had received DMAb or placebo in FREEDOM and provides an opportunity to evaluate the long-term efficacy and safety of continuous DMAb treatment (long-term group), and to replicate the DMAb findings observed in FREEDOM (cross-over group). Here, we report the results from the first 3 years of the Extension, representing up to 6 continuous years of DMAb exposure. Methods: During the Extension, each woman is scheduled to receive 60 mg DMAb every 6 months and supplemental calcium and vitamin D daily. For the analyses reported here, women from the FREEDOM DMAb group received 3 more years of DMAb for a total of 6 years of exposure (long-term group) and women from the FREEDOM placebo group received 3 years of DMAb exposure (cross-over group). Results: Of the 5928 women eligible for the Extension, 4550 (77%) enrolled (N_2343 long-term; N_2207 cross-over). In the long-term group, further significant mean increases in bone mineral density (BMD) occurred 4044 for cumulative 6-year gains of 15.2% at the lumbar spine and 7.5% at the total hip (Figure). During the first 3 years of DMAb treatment during the Extension, the cross-over group had significant mean gains in BMD at the lumbar spine (9.4%) and total hip (4.8%), similar to those observed in the long-term DMAb group during the first 3 years of FREEDOM (lumbar spine, 10.1%; total hip, 5.7%). Serum CTX was rapidly and similarly reduced after the 1st (cross-over) or 7th (long-term) DMAb dose with the characteristic attenuation observed at the end of the dosing period. In the cross-over group, yearly incidences of new vertebral and nonvertebral fractures were lower than in the FREEDOM placebo group. Fracture incidence remained low in the long-term group. Incidences of adverse events (AEs) and serious AEs did not increase over time with DMAb treatment. There were 2 subjects with AEs adjudicated to ONJ in the cross-over group and 2 in the long-term group. Both cases in the cross-over group healed completely and without further complications; 1 of these subjects continues to receive DMAb. Both women in the long-term group continue to be followed. No atypical femur fractures have been observed to date. Figure. Percent changes in bone mineral density during FREEDOM and the Extension Conclusion: DMAb treatment for 6 continuous years (long-term group) remained well tolerated, maintained reduced bone turnover, and continued to significantly increase BMD. Fracture incidence remained low. DMAb treatment for 3 years in the cross-over group reproduced the original observations in FREEDOM
