Asistencia farmacéutica a la prescripción para aproximar la práctica clínica a la evidencia científica

ObjetivoEl objetivo del presente estudio es valorar la utilidad de un programa de asistencia farmacéutica a la prescripción (AFP) en cuanto a la detección de problemas relacionados con los medicamentos.DiseñoRealizamos un estudio descriptivo de los hallazgos de este programa al cabo de 6 meses de rodaje.EmplazamientoEl trabajo fue realizado en 5 centros del Distrito Bahía-Cádiz de Atención Primaria.PacientesSe estudian todos los pacientes (499) incluidos a petición y criterio de su médico, que solicita asesoramiento sobre su farmacoterapia.IntervenciónImplantamos el programa de AFP en pacientes crónicos con dos finalidades básicas:1. Asistencial: detectar problemas relacionados con medicamentos y proponer soluciones individualizadas.2. Docente: aproximar los conocimientos en farmacoterapia aplicados en la práctica clínica a la evidencia científica disponible.Mediciones y resultadosNos centramos en la detección de aquellos problemas relacionados con medicamentos más frecuentes, con incidencia directa y relevante sobre la morbimortalidad. Detectamos 236 casos (47%) de posible mejora terapéutica con implicaciones importantes sobre morbilidad asociada, de los cuales 114 (23%) tenían también implicaciones sobre mortalidad. Un 56% de los pacientes recibía más de 4 medicamentos, polimedicación que podía reducirse fácilmente en un 43,5% de ellos, evitando la utilización de medicamentos de valor intrínseco no elevado.ConclusionesLa utilidad del programa resulta muy elevada al detectar numerosos problemas de gran relevancia clínica y aportar información que puede ser útil al médico para aproximar la farmacoterapia a la evidencia científica disponible.ObjectiveThe objective of this study is to assess the usefulness of a programme of attention to pharmaceutical prescriptions (APP) so as to detect medicine-related problems.DesignA descriptive study of the findings after six months operation of this programme.SettingFive primary care centres in the Bahía-Cádiz Area.PatientsAll the patients (499) who requested advice on their drug therapy and were included at the request and on the criterion of their doctor were studied.InterventionWe introduced the APP programme for chronic patients, with two basic aims:1. Care: to detect medicine-related problems and propose individual solutions.2. Teaching: to bring drug-therapy skills used in clinical practice into line with the scientific evidence available.Measurements and resultsWe focused on the detection of problems related to the most common medicines, with direct and relevant incidence on morbidity and mortality. We detected 236 cases (47%) of possible therapeutic improvement that had important implications for associated morbidity, of which 114 (23%) also had implications for mortality. 56% of the patients took more than 4 medicines, multiple medication that could easily be reduced in 43.5% of cases, so avoiding the use of medicines of low intrinsic value.ConclusionsThe programme was very useful, as numerous very clinically relevant problems were detected and information was gained that the doctor can use to bring drug therapy into line with the available scientific evidence

Seed storage conditions change the germination pattern of clonal growth plants in Mediterranean salt marshes.

8 páginas, 4 tablas, 8 figuras.The effect of salinity level and extended exposure to different salinity and flooding conditions on germination patterns of three saltmarsh clonal growth plants (Juncus subulatus, Scirpus litoralis, and S. maritimus) was studied. Seed exposure to extended flooding and saline conditions significantly affected the outcome of the germination process in a different, though predictable, way for each species, after favorable conditions for germination were restored. Tolerance of the germination process was related to the average salinity level measured during the growth/germination season at sites where established individuals of each species dominated the species cover. No relationship was found between salinity tolerance of the germination process and seed response to extended exposure to flooding and salinity conditions. The salinity response was significantly related to the conditions prevailing in the habitats of the respective species during the unfavorable (nongrowth/nongermination) season. Our results indicate that changes in salinity and hydrology while seeds are dormant affect the outcome of the seed-bank response, even when conditions at germination are identical. Because these environmental-history-dependent responses differentially affect seed germination, seedling density, and probably sexual recruitment in the studied and related species, these influences should be considered for wetland restoration and managementFinancial support from the Spanish Ministry of the Environment (MMA, project 05/99) and the Junta de Andalucía (research group 4086)enabled us to carry out the present work.Peer reviewe

Virulence Regulator EspR of Mycobacterium tuberculosis Is a Nucleoid-Associated Protein

The principal virulence determinant of Mycobacterium tuberculosis (Mtb), the ESX-1 protein secretion system, is positively controlled at the transcriptional level by EspR. Depletion of EspR reportedly affects a small number of genes, both positively or negatively, including a key ESX-1 component, the espACD operon. EspR is also thought to be an ESX-1 substrate. Using EspR-specific antibodies in ChIP-Seq experiments (chromatin immunoprecipitation followed by ultra-high throughput DNA sequencing) we show that EspR binds to at least 165 loci on the Mtb genome. Included in the EspR regulon are genes encoding not only EspA, but also EspR itself, the ESX-2 and ESX-5 systems, a host of diverse cell wall functions, such as production of the complex lipid PDIM (phenolthiocerol dimycocerosate) and the PE/PPE cell-surface proteins. EspR binding sites are not restricted to promoter regions and can be clustered. This suggests that rather than functioning as a classical regulatory protein EspR acts globally as a nucleoid-associated protein capable of long-range interactions consistent with a recently established structural model. EspR expression was shown to be growth phase-dependent, peaking in the stationary phase. Overexpression in Mtb strain H37Rv revealed that EspR influences target gene expression both positively or negatively leading to growth arrest. At no stage was EspR secreted into the culture filtrate. Thus, rather than serving as a specific activator of a virulence locus, EspR is a novel nucleoid-associated protein, with both architectural and regulatory roles, that impacts cell wall functions and pathogenesis through multiple genes

Overlapping political budget cycles in the legislative and the executive

We advance the literature on political budget cycles by testing separately for cycles in expenditures for elections in the legislative and the executive. Using municipal data, we can separately identify these cycles and account for general year effects. For the executive branch, we show that it is important whether the incumbent re-runs. To account for the potential endogeneity associated with this decision, we apply a unique instrumental variables approach based on age and pension eligibility rules. We find sizable and significant effects in expenditures before council elections and before joint elections when the incumbent re-runs

Vote buying or (political) business (cycles) as usual?

We study the short-run effect of elections on monetary aggregates in a sample of 85 low and middle income democracies (1975-2009). We find an increase in the growth rate of M1 during election months of about one tenth of a standard deviation. A similar effect can neither be detected in established OECD democracies nor in other months. The effect is larger in democracies with many poor and uneducated voters, and in Sub-Saharan Africa, Latin America, and in East-Asia and the Pacific. We argue that the election month monetary expansion is related to systemic vote buying which requires significant amounts of cash to be disbursed right before elections. The finely timed increase in M1 is consistent with this; is inconsistent with a monetary cycle aimed at creating an election time boom; and it cannot be, fully, accounted for by alternative explanations
