Abstract
IntroductionPsychomotor agitation is a common psychiatric emergency in our environment that can occur in a wide clinical spectrum. Both the agitation itself as the procedures for their control, carry an implicit risk to patient safety and health workers.ObjectiveTo describe the prevention measures used in patients requiring mechanical restraint in relation to diagnosis of psychiatric disorders.Material and methodsThis is a naturalistic descriptive study. Mechanical restraints made in brief psychiatric hospitalization units of “Hospital del Mar” between January of 2013 to March of 2015, were analyzed by diagnosis. Proportions of the prevention intervention performed by nurses in each episode were compared. The groups of prevention interventions done were: “verbal approach”, “environmental measures”, “psychopharmacological intervention”, “observation increase” and “inability for applying any measure because unpredictability”.ResultsA total of 2986 mechanical restraints were done in brief hospitalization units. Among the results, we find that verbal approach measure was use in 77.23% of patient with personality disorders. Environmental measures were used in 40% of the total of restraints. The most of psychopharmacological intervention was done in alcohol intoxication (50%) and then in psychotic spectrum (42.01%). The inability for applying measures was greater in alcohol intoxication (45.4%).ConclusionSome of the results of this study are interesting and consistent with clinical practice (for example, effectivity of pharmacological intervention in psychosis and bipolar disorders, as well verbal approach in anxiety, etc.), we can predict the usefulness of measures applied to prevent a mechanical restraint. Further research is needed in this topic.Disclosure of interestL. Galindo is a Rio-Hortega-fellowship – (ISC-III; CM14/00111).

Abstract
AIMS To explore whether the transfer of very poor quality (VPQ) embryos is associated with an increase in congenital malformations or perinatal problems. METHODS In this retrospective case-control study, 74 children conceived by in vitro fertilization (IVF) and/or intracytoplasmic sperm injection (ICSI) resulting exclusively from the transfer of VPQ embryos were compared with 1,507 children born after the transfer of top morphological quality (TQ) embryos over the same period of time in the same centers. RESULTS The prevalence of birth defects in children resulting from VPQ embryos was 1.35% (1/74), similar to the 1.72% (26/1,507) when only TQ embryos were transferred; the rate of chromosomal abnormalities detected was also similar (0.0 vs. 0.4%), as was perinatal mortality. After correcting for multiplicity (higher in the TQ group), the aforementioned parameters remained similar in the two groups. CONCLUSION Congenital malformations and perinatal complications do not seem to be more common in children born after transfer of VPQ embryos in IVF/ICSI cycles. Given our preliminary data, which need to be confirmed in much larger studies, when only VPQ embryos are available for transfer in IVF/ICSI cycles, we do not believe that they should be discarded with the intention of avoiding birth defects or perinatal complications.

Abstract
BACKGROUND Clinical experience with the Pipeline Embolization Device (PED) has been widely described in the literature since it obtained its European CE and FDA approvals in 2008 and 2011, respectively. The new generation of PED, the Pipeline Flex Embolization Device, received the CE mark of approval in March 2014. While the implant composition has not changed, its new delivery system has some differences. One of the main changes from the previous generation is a new delivery system that makes the device resheathable until deployed over 90% of its length. We present our preliminary experience using this device. METHODS Between May and June 2014, six patients with six aneurysms were treated with the Pipeline Flex device. RESULTS All devices were placed properly, without technical difficulties. We successfully resheathed and repositioned the device in two cases. Minor and major intraprocedural or periprocedural events were noted. CONCLUSIONS The Pipeline Flex device allows more precise and controlled deployment than the current PED device. Although this preliminary experience seems positive, multicenter larger series will be needed to confirm the safety and durability of this new device.

CHEMOSPHERE 2014; 104:44-50.

Abstract
Due to the concern about the negative effects of exposure to sunlight, combinations of UV filters like 4-Methylbenzylidene-camphor (4-MBC), Benzophenone-3 (BP-3), Benzophenone-4 (BP-4) and 2-Ethylhexyl-4-methoxycinnamate (EHMC) are being introduced in all kind of cosmetic formulas. These chemicals are acquiring a concerning status due to their increasingly common use and the potential risk for the environment. The aim of this study is to assess the behaviour of these compounds in seawater, the toxicity to marine organisms from three trophic levels including autotrophs (Isochrysis galbana), herbivores (Mytilus galloprovincialis and Paracentrotus lividus) and carnivores (Siriella armata), and set a preliminary assessment of potential ecological risk of UV filters in coastal ecosystems. In general, EC50 results show that both EHMC and 4-MBC are the most toxic for our test species, followed by BP-3 and finally BP-4. The most affected species by the presence of these UV filters are the microalgae I. galbana, which showed toxicity thresholds in the range of μg L(-1) units, followed by S. armata>P. Lividus>M. galloprovincialis. The UV filter concentrations measured in the sampled beach water were in the range of tens or even hundreds of ng L(-1). The resulting risk quotients showed appreciable environmental risk in coastal environments for BP-3 and 4-MBC.

Abstract
BACKGROUND Pain and anxiety have been reported as primary concerns for patients with head-and-neck, gynecologic, and prostate cancers undergoing high dose rate (hdr) brachytherapy. However, almost no research has been published on the degree to which these symptoms are experienced by rectal cancer patients undergoing hdr brachytherapy. We conducted a pilot study examining the experiences of rectal cancer patients during hdr brachytherapy, specifically the intensity and trajectory of their anxiety and pain. METHODS Rectal cancer patients (n = 25) who received hdr brachytherapy treatment at a hospital in Montreal, Quebec, completed verbal analog scales for pain and anxiety at 4 time points over 4 treatment days. RESULTS On all 4 days, a subset of patients reported moderate-to-severe anxiety before applicator insertion. Pain increased significantly from the time patients were lying on the table to immediately after insertion of the applicator (p < 0.001). Insertion of the applicator appears to be the most painful part of the procedure, and although anxiety declined to below baseline after applicator removal, pain remained somewhat elevated. Some patients required conscious sedation; however, reports of moderate-to-severe pain were more frequent from patients who received pain medications than from patients who did not receive such medication (p < 0.05). CONCLUSIONS Most patients with rectal cancer tolerated hdr rectal brachytherapy well, although the procedure is stressful and painful for some. Insertion of the applicator was found to be the point of maximal pain, and medication was not always completely successful at alleviating the pain, suggesting that additional psychosocial interventions might be needed, with particular emphasis on the time of applicator insertion.

Abstract
The reported incidence of oligodendrogliomas in the paediatric population is less than 1 %. The posterior fossa is a rare location, with the vast majority arising in the cerebral hemispheres. We report the first paediatric case of a WHO grade II oligodendroglioma arising in the cerebellopontine angle (CPA). CPA oligodendrogliomas in children appear to behave aggressively and adjuvant therapy must be considered early; especially when complete resection cannot be achieved.

Abstract
This study examines the degradation of the antiepileptic carbamazepine (CBZ) by sonolysis, TiO2-based heterogeneous photocatalysis under UV-A and simulated solar irradiation, and by the combined use of UV-A and ultrasound irradiation (i.e. sonophotocatalysis) in demineralized water, ground water and effluent wastewater. The processes were compared with respect to substrate conversion rate and the extent of DOC reduction as a measure of mineralization. CBZ was degraded following a pseudo-first order kinetics. Sonophotocatalysis provided the highest rate of CBZ transformation over the time-course of the experiment while the degree of DOC removal in pure water was similar for all the studied treatments (around 40%), and always lower than CBZ conversion. This indicated that a considerable organic load remained in the treated solutions that could also be attributed to the presence of persistent oxidation products. UPLC-(+ESI)-QToF-MS was employed to determine major CBZ-related transformation products. Several recalcitrant hydroxy- and keto-derivatives of CBZ were tentatively identified. A Daphnia magna bioassay was used to evaluate the potential toxicity of the samples collected at different time points showing that the mixtures were highly toxic to D. magna.

Abstract
This work investigated the application of a solar driven advanced oxidation process (solar Fenton), for the degradation of the antibiotic ofloxacin (OFX) in various environmental matrices at a pilot-scale. All experiments were carried out in a compound parabolic collector pilot plant in the presence of doses of H2O2 (2.5 mg L(-1)) and at an initial Fe(2+) concentration of 2 mg L(-1). The water matrices used for the solar Fenton experiments were: demineralized water (DW), simulated natural freshwater (SW), simulated effluent from municipal wastewater treatment plant (SWW) and pre-treated real effluent from municipal wastewater treatment plant (RE) to which OFX had been spiked at 10 mg L(-1). Dissolved organic carbon removal was found to be dependent on the chemical composition of the water matrix. OFX mineralization was higher in DW (78.1%) than in SW (58.3%) at 12 mg L(-1) of H2O2 consumption, implying the complexation of iron or the scavenging of hydroxyl radicals by the inorganic ions present in SW. On the other hand, the presence of dissolved organic matter (DOM) in SWW and RE, led to lower mineralization per dose of H2O2 compared to DW and SW. The major transformation products (TPs) formed during the solar Fenton treatment of OFX, were elucidated using liquid chromatography-time of flight-mass spectrometry (LC-ToF-MS). The transformation of OFX proceeded through a defluorination reaction, accompanied by some degree of piperazine and quinolone substituent transformation while a hydroxylation mechanism occurred by attack of the hydroxyl radicals generated during the process leading to the formation of TPs in all the water matrices, seven of which were tentatively identified. The results obtained from the toxicity bioassays indicated that the toxicity originates from the DOM present in RE and its oxidation products formed during the photocatalytic treatment and not from the TPs resulted from the oxidation of OFX.

Abstract
The pilot-scale solar degradation of trimethoprim (TMP) in different water matrices (demineralized water: DW, simulated natural freshwater: SW; simulated wastewater: SWW; and real effluent: RE) was investigated in this study. DOC removal was lower in the case of SW compared to DW, which can be attributed to the presence of inorganic anions which may act as scavengers of the HO·. Furthermore, the presence of organic carbon and higher salt content in SWW and RE led to lower mineralization per dose of hydrogen peroxide compared to DW and SW. Toxicity assays in SWW and RE were also performed indicating that toxicity is attributed to the compounds present in RE and their by-products formed during solar Fenton treatment and not to the intermediates formed by the oxidation of TMP. A large number of compounds generated by the photocatalytic transformation of TMP were identified by UPLC-QToF/MS. The degradation pathway revealed differences among the four matrices; however hydroxylation, demethylation and cleavage reactions were observed in all matrices. To the best of our knowledge this is the first time that TMP degradation products have been identified by adopting a solar Fenton process at a pilot-scale set-up, using four different aqueous matrices.

Abstract
Abstract
Background: We already showed that lymphopenia (<1000 lymphocytes/μl) or CD4+ T cell lymphopenia (<450/μl) detected before initiation of chemotherapy are prognostic factors for toxicity and death for metastatic breast cancer (MBC) patients. The goal of the present study was to identify the characteristics of the T cells in these lymphopenic patients. TCR diversity was investigated and tested as a prognostic factor for overall survival (OS).
Patients and methods: The ImmunTraCkeR® assay (ImmunID, Grenoble, France), which analyzes through semi quantitative multiplex-PCR the V-D-J combinatorial diversity of TCR-beta chain (TRB), was used to investigate diversity of T cell repertoire on cryopreserved blood samples from a retrospective cohort of MBC patients before chemotherapy administration (n=66). Univariate and multivariate analysis were performed. We then validated our score on a prospective cohort (n=67) using the same eligibility criteria (MBC patients before first line chemotherapy administration).
Results: Using a 33% cutoff for divpenia in our retrospective cohort (T cell diversity below 33%) (average diversity for healthy people is 70%), divpenia was associated with a median OS of 10 months vs 22 months for patients with diversity >33% (logrank p value=0.04). The NDL® score (Numeration Diversity Lymphocytes representation) that combines lymphocyte numeration with TRB diversity, demonstrated that lympho-divpenia (T cell diversity below 33% and lymphopenia below lGiga/L) was associated with a poor OS compared to patients with either lymphocyte <1000/μL & diversity >33% or lymphocyte >1000/μL & diversity <33% or both lymphocyte >1000/μL and diversity >33% (p=0.015). In multivariate analysis, including performance status (PS), hemoglobin level, polynuclear neutrophil count (PNN), age, and liver metastasis, NDL® score was identified as an independent prognostic factor for OS. In our prospective validation cohort, NDL® score was also identified as a prognostic factors for OS (p=0,007), as well as lymphopenia (<1000/μL) (p=0,0003), CD4+ lymphopenia (<450/μL) (p=0,04), menopausal status (p=0,02), hormonal receptor status (estrogen receptor p=0.02; progesterone receptor p=0.002) and lung metastasis (p=0,009). In multivariate analysis, hemoglobin level was the only independent prognostic factor in this cohort.
Conclusion: We showed that Divpenia and NDL® score are prognostic factors for OS in MBC patients. In order to confirm these results, a prospective clinical trial is ongoing on a larger cohort of MBC and lung cancer patients.
