    Abstract Twenty-six common ingredients of personal care products (PCPs) in water, sediment and fish from the Evrotas River (Greece) were investigated. Water sample analysis revealed the occurrence of twenty PCPs at concentrations ranging from 2.8 to 2031.0 ng l−1, the maximum corresponding to the endocrine disrupting UV filter benzophenone 3 (BP3). In sediment samples, six compounds were found to be adsorbed, the highest concentration being that of 4-methylbenzylidene camphor (4MBC, 1400.4 ng g−1 dw). Evrotas cyprinid fish (Squalius keadicus) showed a high accumulation potential for these chemicals, 100% detection frequency with maximum concentration that of benzophenone 2 (BP2, 41.9 ng g−1 dw). These data allowed estimating the distribution coefficients sediment-water (DCs-w) and the bioaccumulation factors (BAFs) of the pollutants investigated. Calculated rates revealed that benzophenone 1 (BP1), 4-hydroxybenzophenone (4HB) and ethyl-4-(dimethyl-amino)benzoate (EtPABA) have a strong tendency to adsorb onto the sediments, showing high DCs-w, i.e. 8.2E + 4 l g−1, 6.7E + 4 l g−1 and 5.7E + 3 l g−1, respectively. BFAs were only estimated for 5-methyl benzotriazole (MeBT), the compound having paired data from fish and water. The obtained values (range 2.0E + 2 l g−1–3.8E + 3 l g−1), indicated MeBT's strong bioaccumulation. Risk assessment of the investigated compounds for several aquatic organisms indicated a high ecological risk (HQ > 1) for BP3 and medium ecological risk (HQ ~ 0.5) for ODPABA.

    Abstract A new voltammetric methodology is proposed for the simultaneous determination of the organic UV filters oxybenzone (benzophenone 3, BP3) and octocrylene (OC) in personal care products and in wastewater extracts. It is based on previous adsorptive stripping voltammetric (AdSV) methods developed for hanging mercury drop electrodes, adapted to the special characteristics of carbon-based screen-printed electrodes. Among the carbon substrates tested, regular carbon screen-printed devices exhibited the best performance, with detection limits of 4.8 and 6.6 μmol L−1 and linearity ranges of 16–400 and 22–400 μmol L−1 for BP3 and OC, respectively, and, as compared to mercury electrodes, with the advantages of environmental safety, easy of use, low cost and compatibility with automation and flow measurements. The methodology has been successfully tested in real samples and compared to the standard methodology by liquid chromatography – tandem mass spectrometry (LC-MS/MS).

    Abstract Cinnamaldehyde is a naturally occurring α,β-unsaturated aldehyde. Its potential as a natural cross-linker to improve the physical performance of cast wheat gliadin films was evaluated. The cross-linking reaction was found to be dependent on the pH of the reaction medium, with pH 2 as the optimum. The water resistance (weight loss after immersion), mechanical properties (Young's modulus, tensile strength and elongation at break), thermal properties (Tg and decomposition behavior), optical properties and morphology of films were evaluated. Cross-linked films showed high transparency, maintained their integrity after immersion, and displayed significant improvements in tensile strength and Young's modulus without impairment of their elongation properties. These effects, which were proportional to the amount of cinnamaldehyde added, highlight the possible formation of intermolecular covalent bonds between "monomeric" gliadins, leading to a polymerized network. Thus, this treatment could provide a new alternative to the toxic cross-linkers commonly employed and so extend the use of gliadin films.

    Abstract The aim of this work has been to study the modification of gliadin films with cinnamaldehyde as a potential cross-linker agent. The molecular weight profile and cross-linking density showed that cinnamaldehyde increased reticulation in the resulting films. The participation of free amino groups of the protein in the newly created entanglements could be a possible mechanism of connection between the polypeptidic chains. The combination of a Schiff base and a Michael addition is a feasible approach to understanding this mechanism. The protein solubility in different media pointed to lower participation by both noncovalent and disulfide bonds in stabilizing the structure of the cross-linked films. The new covalent bonds formed by the cinnamaldehyde treatment hampered water absorption and weight loss, leading to more water-resistant matrices which had not disintegrated after 5 months. The properties of this novel bioplastic could be modified to suit the intended application by using cinnamaldehyde, a naturally occurring compound.

    Abstract Objective: The psycho-social needs of patients with advanced chronic illness and their families include emotional, spiritual, and bereavement care. With a funding initiative by the La Caixa Foundation and design by the WHO Collaborating Center, we developed and implemented a program for the comprehensive care of terminally-ill individuals and their families, in Spain. The intent was to improve the psycho-social and spiritual dimensions of care, to generate experience and evidence, to explore models, and to act as catalyst in the Spanish National Strategy for Palliative Care.
    Method: We reviewed the process of design, implementation, and initial evaluation of the program at 18 months.
    Results: Thirty psycho-social teams' (PST) acting as support teams projects were initiated. There were 120 full-time healthcare professionals appointed (58% clinical psychologists). These professionals received training through a comprehensive postgraduate course, and all used the same documentation. Some results were collated 18 months post-implementation. The total number of patients attended to was 10,954, and the number of relatives was 17,715. The preliminary clinical outcomes show a significant improvement in well-being, and a decrease in anxiety and insomnia, although there was a smaller impact on alleviating depression. Healthcare professionals collated results on satisfaction with palliative care (PC) services.
    Significance of results: Based on these preliminary results, we suggest that the PST can be a model of organization that is effective and efficient in improving the psycho-social and spiritual aspects of care of terminally ill patients. Further follow-up and evaluation with validated tools are the main goals for the immediate future.

    Title translation Community-onset and nosocomial bacteremia due to methicillin-resistant Staphylococcus aureus in Spanish hospitals.
    Abstract Introduction: Community-onset infections caused by methicillin-resistant Staphylococcus aureus (MRSA) are increasing. However, there is little information about community-onset bacteremia (CB) due to MRSA in Spain. The objectives of this study were to evaluate the prevalence, clinical and molecular epidemiology, clinical features, and prognosis of CB due to MRSA in comparison with nosocomial bacteremia (NB).
    Methods: Prospective multicenter cohort study; all new cases of bacteremia due to MRSA occurring during June 2003 in 59 Spanish hospitals were included. Episodes diagnosed during the first 48 hours of admission were considered CB, and otherwise, NB. Isolates were typed by pulsed field electrophoresis and multilocus sequence typing. Staphylococcal cassete chromosome mec types and Panton-Valentine leukocidin genes were studied by polymerase chain reaction.
    Results: Sixty-four cases were included; 21 (33%) were classified as CB. In all CB cases, a relation was found with health care, or the isolate proved to be clonally related to nosocomial isolates. There were no significant differences between the groups in terms of demographic data, underlying conditions, prognosis, or characteristics of the isolates. Regarding the source of bacteremia, catheter-related cases were more frequent in NB than CB (39.5% vs 5%, P=0.005), whereas a urinary source was more frequent in CB than NB (25% vs 0%, P=0.001). Most isolates belonged to 2 clones related to the pandemic "pediatric" clone.
    Conclusion: MRSA should be considered in empiric treatment for certain infectious syndromes in patients with healthcare-associated community-onset sepsis.
