Antibiotic-dependent correlation between drug-induced killing and loss of luminescence in Streptococcus gordonii expressing luciferase.

Measuring antibiotic-induced killing relies on time-consuming biological tests. The firefly luciferase gene (luc) was successfully used as a reporter gene to assess antibiotic efficacy rapidly in slow-growing Mycobacterium tuberculosis. We tested whether luc expression could also provide a rapid evaluation of bactericidal drugs in Streptococcus gordonii. The suicide vectors pFW5luc and a modified version of pJDC9 carrying a promoterless luc gene were used to construct transcriptional-fusion mutants. One mutant susceptible to penicillin-induced killing (LMI2) and three penicillin-tolerant derivatives (LMI103, LMI104, and LMI105) producing luciferase under independent streptococcal promoters were tested. The correlation between antibiotic-induced killing and luminescence was determined with mechanistically unrelated drugs. Chloramphenicol (20 times the MIC) inhibited bacterial growth. In parallel, luciferase stopped increasing and remained stable, as determined by luminescence and Western blots. Ciprofloxacin (200 times the MIC) rapidly killed 1.5 log10 CFU/ml in 2-4 hr. Luminescence decreased simultaneously by 10-fold. In contrast, penicillin (200 times the MIC) gave discordant results. Although killing was slow (< or = 0.5 log10 CFU/ml in 2 hr), luminescence dropped abruptly by 50-100-times in the same time. Inactivating penicillin with penicillinase restored luminescence, irrespective of viable counts. This was not due to altered luciferase expression or stability, suggesting some kind of post-translational modification. Luciferase shares homology with aminoacyl-tRNA synthetase and acyl-CoA ligase, which might be regulated by macromolecule synthesis and hence affected in penicillin-inhibited cells. Because of resemblance, luciferase might be down-regulated simultaneously. Luminescence cannot be universally used to predict antibiotic-induced killing. Thus, introducing reporter enzymes sharing mechanistic similarities with normal metabolic reactions might reveal other effects than those expected.

Increased α2- and β1-adrenoceptor densities in postmortem brain of subjects with depression: differential effect of antidepressant treatment.

BACKGROUND: Brain α2- and β-adrenoceptor alterations have been suggested in suicide and major depressive disorder. METHODS: The densities of α2-, β1- and β2-adrenoceptors in postmortem prefrontal cortex of 26 subjects with depression were compared with those of age-, gender- and postmortem delay-matched controls. The effect of antidepressant treatment on α2- and β-adrenoceptor densities was also evaluated. α2- and β-adrenoceptor densities were measured by saturation experiments with respective radioligands [(3)H]UK14304 and [(3)H]CGP12177. β1- and β2-adrenoceptor subtype densities were dissected by means of β1-adrenoceptor selective antagonist CGP20712A. RESULTS: Both, α2- and β1-adrenoceptors densities were higher in antidepressant-free depressed subjects (n=14) than those in matched controls (Δ~24%, p=0.013 and Δ~20%, p=0.044, respectively). In antidepressant-treated subjects (n=12), α2-adrenoceptor density remained increased over that in controls (Δ~20%), suggesting a resistance of α2-adrenoceptors to the down-regulatory effect of antidepressants. By contrast, β1-adrenoceptor density in antidepressant-treated depressed subjects was not different from controls, suggesting a possible down-regulation by antidepressants. The down-regulation of β1-adrenoceptor density in antidepressant-treated depressed subjects differs from the unaltered β1-adrenoceptor density observed in citalopram-treated rats and in a group of non-depressed subjects also treated with antidepressants (n=6). β2-adrenoceptor density was not altered in depressed subjects independently of treatment. LIMITATIONS: Antidepressant-treated subjects had been treated with a heterogeneous variety of antidepressant drugs. The results should be understood in the context of suicide victims with depression. CONCLUSIONS: These results show the up-regulation of brain α2- and β1-adrenoceptors in depression and suggest that the regulation induced by chronic antidepressant treatment would be altered in these subjects.

Ética y muerte digna

This book is an study about the bill of Death with Dignity Act, written by the Andalusian Commission on Healthcare Ethics and Research. The aim of the Act would be to “establish the criteria and conditions to be adopted by the health system to guarantee adequate healthcare during life’s final process based on the prevention of suffering and respect for each person’s dignity and free choice”.

Entourage des patients âgés avec une pathologie mentale [Carers of elderly patients suffering from mental disorders]

Mental disorders in the elderly lead their families to stand in and adopt a variety of roles before institutional care takes over. These pathologies carry a high risk of suffering for families and distress for professional caregivers. Thus, the psychological burden endured by the proxies of an elderly depressed patient, or of one who has committed suicide, or of patient suffering from dementia needs special attention and, in some cases, professional care. The discussion of these paradigmatic situations in this manuscript will be extended by a paragraph on specific stakes raised by alcoholic patients living in nursing homes. It will stress the complexity and requirements of professionalism when approaching the familial and professional circle of the elderly psychiatric patient.

Caspase-3 Protects Stressed Organs against Cell Death.

The ability to generate appropriate defense responses is crucial for the survival of an organism exposed to pathogenesis-inducing insults. However, the mechanisms that allow tissues and organs to cope with such stresses are poorly understood. Here we show that caspase-3-knockout mice or caspase inhibitor-treated mice were defective in activating the antiapoptotic Akt kinase in response to various chemical and environmental stresses causing sunburns, cardiomyopathy, or colitis. Defective Akt activation in caspase-3-knockout mice was accompanied by increased cell death and impaired survival in some cases. Mice homozygous for a mutation in RasGAP that prevents its cleavage by caspase-3 exhibited a similar defect in Akt activation, leading to increased apoptosis in stressed organs, marked deterioration of their physiological functions, and stronger disease development. Our results provide evidence for the relevance of caspase-3 as a stress intensity sensor that controls cell fate by either initiating a RasGAP cleavage-dependent cell resistance program or a cell suicide response.

Prevención de los comportamientos sexuales de riesgo en los adolescentes: SIDA, otras enfermedades de transmisión sexual y embarazos no deseados

En la actualidad, los adolescentes son uno de los grupos que por sus características conductuales, cognitivas y sociales, se encuentran en mayor riesgo frente al posible contagio con el VIH. Esta amenaza para la salud y el bienestar de los adolescentes, se ha venido a sumar a otros problemas ya existentes en este colectivo: los embarazos no deseados y las enfermedades de transmisión sexual (ETS), que también se derivan de la no utilización de precauciones en las relaciones sexuales. En este trabajo se exponen diversos factores biológicos, psicológicos (conductuales y cognitivos) y sociales que pueden facilitar, dificultar o impedir los comportamientos sexuales de prevención de los adolescentes, y se revisan y valoran algunas de las intervenciones preventivas realizadas. A partir de esta revisión se argumenta sobre la conveniencia de unificar los programas para la prevención simultánea de los tres trastornos, maximizando de esta forma los recursos disponibles

5-Fluorouracil-loaded poly(ε-caprolactone) nanoparticles combined with phage E gene therapy as a new strategy against colon cancer

This work aimed to develop a new therapeutic approach to increase the efficacy of 5-fluorouracil (5-FU) in the treatment of advanced or recurrent colon cancer. 5-FU-loaded biodegradable poly(ε-caprolactone) nanoparticles (PCL NPs) were combined with the cytotoxic suicide gene E (combined therapy). The SW480 human cancer cell line was used to assay the combined therapeutic strategy. This cell line was established from a primary adenocarcinoma of the colon and is characterized by an intrinsically high resistance to apoptosis that correlates with its resistance to 5-FU. 5-FU was absorbed into the matrix of the PCL NPs during synthesis using the interfacial polymer disposition method. The antitumor activity of gene E from the phage ϕX174 was tested by generating a stable clone (SW480/12/E). In addition, the localization of E protein and its activity in mitochondria were analyzed. We found that the incorporation of 5-FU into PCL NPs (which show no cytotoxicity alone), significantly improved the drug's anticancer activity, reducing the proliferation rate of colon cancer cells by up to 40-fold when compared with the nonincorporated drug alone. Furthermore, E gene expression sensitized colon cancer cells to the cytotoxic action of the 5-FU-based nanomedicine. Our findings demonstrate that despite the inherent resistance of SW480 to apoptosis, E gene activity is mediated by an apoptotic phenomenon that includes modulation of caspase-9 and caspase-3 expression and intense mitochondrial damage. Finally, a strongly synergistic antiproliferative effect was observed in colon cancer cells when E gene expression was combined with the activity of the 5-FU-loaded PCL NPs, thereby indicating the potential therapeutic value of the combined therapy.

Prédiction de la réponse aux SSRI chez les patients avec épisode majeur de dépression par l'étude du métabolisme cérébral par PET/CT au F-18-FDG

Contexte : Les patients souffrant d'un épisode dépressif sévère sont fréquemment traités par des inhibiteurs sélectifs de la recapture de la sérotonine (SSRI). Cependant, seulement 30-50% des patients répondront à ce type de traitement. Actuellement, il n'existe pas de marqueur biologique utilisable pour prédire la réponse à un traitement par SSRI. Un délai dans la mise en place d'une thérapie efficace peut avoir comme conséquences néfastes une augmentation du risque de suicide et une association avec un moins bon pronostic à long terme lors d'épisodes ultérieurs. Objectif : Par l'étude du métabolisme cérébral par tomographie par émission de positons (PET) au F-18-fluorodeoxyglucose (FDG), nous étudierons la présence de corrélations éventuelles entre la réponse clinique, qui généralement survient dans les 4 à 6 semaines après l'instauration du traitement antidépresseur, et une modification du métabolisme cérébral mesuré plus précocement, dans le but d'identifier les futurs répondeurs au traitement par SSRI. Méthodes : Cette étude longitudinale comprendra 20 patients unipolaires avec un épisode dépressif sévère au bénéfice d'un traitement par SSRI. Chacun des patients aura deux examens PET cérébraux au F-18-FDG. Le premier PET aura lieu juste avant le début du traitement aux SSRI et le second dans la 3ème semaine après début du traitement. La réponse clinique sera mesurée à 3 mois, et les répondeurs seront identifiés par une diminution significative des scores lors d'évaluation sur échelles de dépression. La recherche d'altérations métaboliques cérébrales sera faite en évaluant: (1) l'examen de base ou (2) l'examen PET précoce, à la recherche d'altérations spécifiques corrélées à une bonne réponse clinique, afin d'obtenir une valeur pronostique quant à la réponse au traitement. L'analyse de l'imagerie cérébrale utilisera la technique SPM (Statistical Parameter Mapping) impliquant un traitement numérique voxel par voxel des images PET. Résultats escomptés : Cette étude caractérisant les variations du métabolisme cérébral dans la phase précoce d'un traitement par SSRI vise à identifier des marqueurs métaboliques potentiels fournissant une valeur prédictive quant à la future efficacité du traitement SSRI introduit. Plus-value escomptée : L'identification d'un tel marqueur métabolique permettrait d'identifier rapidement les futurs répondeurs aux SSRI, et par conséquent d'éviter de proposer aux non-répondeurs la poursuite d'une médication, pendant plusieurs semaines, qui aurait peu de chance d'être efficace. Ainsi, une identification précoce des répondeurs aux SSRI pourrait permettre d'éviter des délais dans la mise en place d'une thérapie efficace et d'obtenir une amélioration du pronostic à plus long terme, avec une influence favorable sur les coûts de la santé.

La eutanasia en Bélgica.

The experience of the Netherlands in relation with the legalization and practice of euthanasia is better known in Spain than the Belgian experience in this matter. But the historical process of social debate in Belgium has many specific details which should be known by Spanish healthcare professionals, bioethicists, politicians and lawyers. This paper begins with a comparative analysis of both countries: Spain and Belgium and follows with a description of the milestones of the historical process of debating and, finally, passing the Belgian Law on Euthanasia in 2002. The next chapter consists of a description of the main contents of this important Law. The paper continues then with an approach to the epidemiology of the practice of euthanasia in Belgium and finishes with a description of the different positions of the actors of the process. Two positions are described more in depth: the opinion of the specialists in palliative care, and the opinion of the Catholic Church. The paper ends underlining the reason for the incorporation of the Belgian experience on euthanasia to the debate about the possibility of legalizing euthanasia in Spain.

Toward an integration of spirituality and religiousness into the psychosocial dimension of schizophrenia.

OBJECTIVE: Spirituality and religiousness have been shown to be highly prevalent among patients with schizophrenia. However, clinicians are rarely aware of the importance of religion and understand little of the value or difficulties it presents to treatment. This study aimed to assess the role of religion as a mediating variable in the process of coping with psychotic illness. METHOD: Semistructured interviews about religious coping were conducted with a sample of 115 outpatients with psychotic illness. RESULTS: For some patients, religion instilled hope, purpose, and meaning in their lives (71%), whereas for others, it induced spiritual despair (14%). Patients also reported that religion lessened (54%) or increased (10%) psychotic and general symptoms. Religion was also reported to increase social integration (28%) or social isolation (3%). It may reduce (33%) or increase (10%) the risk of suicide attempts, reduce (14%) or increase (3%) substance use, and foster adherence to (16%) or be in opposition to (15%) psychiatric treatment. CONCLUSIONS: Our results highlight the clinical significance of religion in the care of patients with schizophrenia. Religion is neither a strictly personal matter nor a strictly cultural one. Spirituality should be integrated into the psychosocial dimension of care. Our results suggest that the complexity of the relationship between religion and illness requires a highly sensitive approach to each unique story.

The use of palliative sedation: A comparison of attitudes of French-speaking physicians from Quebec and Switzerland.

OBJECTIVE: Previous literature has suggested that laws and regulations may impact the use of palliative sedation. Our present study compares the attitudes of French-speaking physicians practicing in the Quebec and Swiss environments, where different laws are in place regarding physician-assisted suicide. METHOD: Data were drawn from two prior studies, one by Blondeau and colleagues and another by Beauverd and coworkers, employing the same two-by-two experimental design with length of prognosis and type of suffering as independent variables. Both the effect of these variables and the effect of their interaction on Swiss and Quebec physicians' attitudes toward sedation were compared. The written comments of respondents were submitted to a qualitative content analysis and summarized in a comparative perspective. RESULTS: The analysis of variance showed that only the type of suffering had an effect on physicians' attitudes toward sedation. The results of the Wilcoxon test indicated that the attitudes of physicians from Quebec and Switzerland tended to be different for two vignettes: long-term prognosis with existential suffering (p = 0.0577) and short-term prognosis with physical suffering (p = 0.0914). In both cases, the Swiss physicians were less prone to palliative sedation. SIGNIFICANCE OF RESULTS: The attitudes of physicians from Quebec and Switzerland toward palliative sedation, particularly regarding prognosis and type of suffering, seem similar. However, the results suggest that physicians from Quebec could be slightly more open to palliative sedation, even though most were not in favor of this practice as an answer to end-of-life existential suffering.
