Implantación del distintivo de garantía de calidad ambiental en hoteles de 3*, 4* y 5* de Sitges

Este proyecto tiene como objetivo estudiar la viabilidad de la implantación del Distintivo de Garantía de Calidad Ambiental (DGQA) en los hoteles de 3*, 4* y 5* del municipio de Sitges, perteneciente a la comarca del Garraf. El criterio de selección se ha basado en el estado del hotel (abierto o cerrado) en que se encontraba en el momento del estudio. Para conocer la gestión ambiental de los establecimientos hoteleros se llevó a cabo la realización de unas encuestas elaboradas a partir de los criterios requeridos por el DGQA, tanto obligatorios como opcionales. Los resultados obtenidos muestran un elevado cumplimiento de la puntuación obligatoria, así como la totalidad de los criterios opcionales requeridos. No se han detectado diferencias significativas entre las tres categorías hoteleras. Sin embargo, sí que aparecen diferencias entre los ámbitos propuestos por el DGQA, destacando el elevado cumplimiento en integración paisajística, ruidos y vibraciones, y diseño de espacios exteriores. Por el contrario se observa una carencia relevante en los ámbitos de compras y residuos. Finalmente se han propuesto las acciones de mejora necesarias para dicha obtención, obteniendo así un presupuesto aproximado para la consecución del distintivo por cada uno de los hoteles.

In Vitro and in Vivo Assays of 3,5-Disubstituted-Tetrahydro-2H-1,3,5-Thiadiazin-2-Thione Derivatives against Trypanosoma cruzi

Cytotoxicity assays of 24 new 3,5-disubstituted-tetrahydro-2H-1,3,5-thiadiazin-2-thione derivatives were performed. The 17 compounds with higher anti-epimastigote activity and lower cytotoxicity were, thereafter, screened against amastigote of Trypanosoma cruzi. Out of these 17 derivatives S-2d was selected to be assayed in vivo, because of its remarkable trypanocidal properties. To determine toxicity against J774 macrophages, a method based on quantification of cell damage, after 24 h, was used. Cell respiration, an indicator of cell viability, was assessed by the reduction of MTT [3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide] to formazan. Anti-amastigote activity was estimated after 48 h by microscopic counts of May Grünwald-Giemsa-stained monolayers. Nifurtimox and benznidazole were used as reference drugs. For the in vivo experiences, mice were infected with 10(4) blood trypomastigotes and then treated during 15 days with S-2d or nifurtimox by oral route. All of the compounds were highly toxic at 100 µg/ml for macrophages and a few of them maintained this cytotoxicity even at 10 µg/ml. Of the derivatives assayed against amastigotes 3k and S-2d showed an interesting activity, that was held even at 1µg/ml. It is demonstrated that the high anti-epimastigote activity previously reported is mainly due to the non-specific toxicity of these compounds. In vivo assays assessed a reduction of parasitemia after administration of S-2d to infected mice.

Seguimiento a 5 años de pacientes con hepatits crónica C y respuesta viral sostenida

L'objectiu va ser avaluar la persistència de resposta viral sostinguda als 5 anys de seguiment en pacients amb hepatitis crònica per virus C tractats amb interferó pegilat i ribavirina. Des d'agost de 2001 fins a maig de 2004, es van incloure tots els pacients del nostre centre tractats amb interferó pegilat i ribavirina que van assolir resposta viral sostinguda. Es van recollir dades demogràfiques, histològiques, bioquímics i virològiques durant el tractament i als 5 anys d'haver obtingut la resposta viral sostinguda. Només un dels pacients va presentar recurrència virològica (taxa de recurrència viral a llarg termini molt baixa).

Efficacy and safety of various combination therapies based on a calcium antagonist in essential hypertension: results of a placebo-controlled randomized trial

We tested the efficacy and safety of different combination therapies in hypertensive patients with uncontrolled blood pressure (BP) on a monotherapy with a calcium antagonist: 1,647 hypertensive patients were enrolled to receive placebo for 4 weeks followed by isradipine (ISR) 2.5 mg twice daily (b.i.d.) for 4 weeks. Nonresponders [diastolic BP (DBP) > 90 mm Hg] were randomly assigned to receive either the beta-blocker bopindolol 0.5 or 1 mg/day, the diuretic metolazone 1.25 or 2.5 mg/day, the angiotensin-converting enzyme (ACE) inhibitor enalapril 10 or 20 mg/day, ISR 5 mg b.i.d., or placebo. One hundred seventy-five receiving placebo dropped out; 93% (n = 1,376) of the 1,472 patients finished 4-week monotherapy with ISR. Sixty percent (n = 826) reached target BP, and 40% (n = 550) remained uncontrolled and were randomized. Regardless of dosage, all drugs led to a comparable reduction in BP except for the lower dosage of bopindolol and ISR 5 mg b.i.d., which were less effective in lowering systolic BP (SBP). The BP decrease achieved by combination therapy ranged from 10 to 15 mm Hg SBP and from 7 to 11 mm Hg DBP but remained unchanged with placebo. Side effects were minor, and only 2.4% of patients discontinued therapy because of side effects. The side-effect score for edema was lower with ISR plus diuretics than with other combinations, whereas the ACE inhibitor was associated with a higher score for cough. Monotherapy with a calcium antagonist normalizes BP in about two-thirds of patients when used in general practice.(ABSTRACT TRUNCATED AT 250 WORDS)

The gap between scientific evidence and clinical practice : 5-aminosalicylates are frequently used for the treatment of Crohn's disease

BACKGROUND: There is uncertain evidence of effectiveness of 5-aminosalicylates (5-ASA) to induce and maintain response and remission of active Crohn's disease (CD), and weak evidence to support their use in post-operative CD. AIM: To assess the frequency and determinants of 5-ASA use in CD patients and to evaluate the physicians' perception of clinical response and side effects to 5-ASA. METHODS: Data from the Swiss Inflammatory Bowel Disease Cohort, which collects data since 2006 on a large sample of IBD patients, were analysed. Information from questionnaires regarding utilisation of treatments and perception of response to 5-ASA were evaluated. Logistic regression modelling was performed to identify factors associated with 5-ASA use. RESULTS: Of 1420 CD patients, 835 (59%) were ever treated with 5-ASA from diagnosis to latest follow-up. Disease duration >10 years and colonic location were both significantly associated with 5-ASA use. 5-ASA treatment was judged to be successful in 46% (378/825) of treatment episodes (physician global assessment). Side effects prompting stop of therapy were found in 12% (98/825) episodes in which 5-ASA had been stopped. CONCLUSIONS: 5-Aminosalicylates were frequently prescribed in patients with Crohn's disease in the Swiss IBD cohort. This observation stands in contrast to the scientific evidence demonstrating a very limited role of 5-ASA compounds in the treatment of Crohn's disease.

Cyclic 3'-5' guanosine monophosphate-dependent activity in Leishmania amazonensis

Although there are some data concerning the nitric oxide and the cyclic 3'-5'guanosine monophosphate (cGMP) signaling pathway in trypanosomatids, there is no report about the cGMP-dependent enzymatic activity identification. In this sense, a cGMP dependent activity was detected on soluble fraction from Leishmania amazonensis promastigotes with a high metacyclic level. This information is valuable in order to explore the metabolic pathway of G kinase protein in this parasite.

Drug use in Ireland and Northern Ireland 2010/11 Drug Prevalence Survey: Polydrug Use Results: Bulletin 5

This bulletin presents key findings regarding polydrug use (the use of more than one substance within a specific time period) in Ireland. These are based on the drug prevalence survey of households in Ireland and Northern Ireland. A representative sample of adults aged between 15 and 64 years was sampled during late 2010 and early 2011. The bulletin presents prevalence rates for combinations of both legal and illegal drug use for the Republic of Ireland and also examines gender and age differences and the relationship between the use of a particular substance and the use of another substance. The survey was carried out according to standards set by the European Monitoring Centre for Drugs and Drug Addiction (EMCDDA). View the report here.

Alteration in neuromuscular function after a 5 km running time trial.

The aim of this study was to characterize the effect of a 5 km running time trial on the neuromuscular properties of the plantar flexors. Eleven well-trained triathletes performed a series of neuromuscular tests before and immediately after the run on a 200 m indoor track. Muscle activation (twitch interpolation) and normalized EMG activity were assessed during maximal voluntary contraction (MVC) of plantar flexors. Maximal soleus H-reflexes and M-waves were evoked at rest (i.e. H (MAX) and M (MAX), respectively) and during MVC (i.e. H (SUP) and M (SUP), respectively). MVC significantly declined (-27%; P < 0.001) after the run, due to decrease in muscle activation (-8%; P < 0.05) and M (MAX)-normalized EMG activity (-13%; P < 0.05). Significant reductions in M-wave amplitudes (M (MAX): -13% and M (SUP): -16%; P < 0.05) as well as H (MAX)/M (MAX) (-37%; P < 0.01) and H (SUP)/M (SUP) (-25%; P < 0.05) ratios occurred with fatigue. Following exercise, the single twitch was characterized by lower peak torque (-16%; P < 0.001) as well as shorter contraction (-19%; P < 0.001) and half-relaxation (-24%; P < 0.001) times. In conclusion, the reduction in plantar flexors strength induced by a 5 km running time trial is caused by peripheral adjustments, which are attributable to a failure of the neuromuscular transmission and excitation-contraction coupling. Fatigue also decreased the magnitude of efferent motor outflow from spinal motor neurons to the plantar flexors and part of this suboptimal neural drive is the result of an inhibition of soleus motoneuron pool reflex excitability.

Ampakine CX546 bolsters energetic response of astrocytes: a novel target for cognitive-enhancing drugs acting as alpha-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA) receptor modulators.

Glutamate was previously shown to enhance aerobic glycolysis i.e. increase glucose utilization and lactate production with no change in oxygen levels, in mouse cortical astrocytes by a mechanism involving glutamate uptake. It is reported here that a similar response is produced in both hippocampal and cerebellar astrocytes. Application of the cognitive-enhancing drug CX546 promoted further enhancement of glucose utilization by astrocytes from each brain area following glutamate exposure. alpha-Amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA) receptors represent the purported molecular target of cognitive-enhancing drugs such as CX546, and the presence of AMPA receptor subunits GluR1-4 was evidenced in astrocytes from all three regions by immunocytochemistry. AMPA itself did not stimulate aerobic glycolysis, but in the presence of CX546, a strong enhancement of glucose utilization and lactate production was obtained in cortical, hippocampal and cerebellar astrocytes. The effect of CX546 was concentration-dependent, with an EC(50) of 93.2 microm in cortical astrocytes. AMPA-induced glucose utilization in the presence of CX546 was prevented by the AMPA receptor antagonist 6-cyano-7-nitroquinoxaline-2,3-dione (CNQX) and the negative modulator GYKI 52466. In addition, the metabolic effect of CX546 in the presence of AMPA was mimicked by the AMPA receptor modulator cyclothiazide. Our data suggest that astrocyte energetics represents a novel target for cognitive-enhancing drugs acting as AMPA receptor modulators.

Reducing unintentional injuries in and around the home among children under 5 Years

Public Health England today launches 2 new resources for local authorities on preventing accidents to children and young people in the home and on the road. The reports show whilst the number of children and young people killed or seriously injured continues to fall in England there are still significant numbers of deaths and emergency admissions from preventable causes. On average each year between 2008 to 2012, 525 children and young people under 25 died and there were more than 53,700 admissions to hospital. The reports highlight actions local partners can take to reduce accidents including improving safety for children travelling to and from school and using existing services like health visitors and children’s centres. The Reducing unintentional injuries in and around the home among children under 5 Years and the Reducing unintentional injuries on the roads among children and young people under 25 reports include an analysis of data between 2008 to 2012. Key findings from the reports include: home injuries (under 5 years of age): an average of 62 children died each year between 2008 and 2012 these injuries result in an estimated 40,000 emergency hospital admissions among children of this age each year 5 injury types should be prioritised for the under-fives: choking; suffocation and strangulation; falls; poisoning; burns and scalds; and drowning hospital admission rate for unintentional injuries among the under-fives is 45% higher for children from the most deprived areas compared with children from the least deprived Road traffic injuries (under 25 years of age) there were 2,316 deaths recorded by the police among road users under the age of 25 years, an average of 463 under 25s each year there were 68,657 admissions to hospital as a result of road traffic injuries, an average of 13,731 each year in total there were 322,613 casualties of all severities recorded by the police, an average of 64,523 each year the rate of fatal and serious injuries for 10to 14 year olds was significantly greater for children from the 20% most deprived areas (37 per 100,000) compared with those from the most affluent areas (10 per 100,000)
