Hospital readmission within 30 days of older adults hospitalized in a public hospital

Older adults have difficulty monitoring their drug therapy in the first thirty days following hospital discharge. This transition care period may trigger hospital readmissions. The study aims to identify the factors associated with the readmission of older adults 30 days after discharge from the perspective of drug therapy. This is a cross-sectional study and hospital admission within 30 days was defined as readmission to any hospital 30 days after discharge. The complexity of the drug therapy was established by the Medication Regimen Complexity Index (MRCI).. Readmission risks were predicted by the "Readmission Risk Score - RRS". The multivariate logistic regression was used to identify factors associated with readmission within 30 days after discharge. Two hundred fifty-five older adults were included in the study, of which 32 (12.5%) had non-elective hospital readmission. A higher number of readmissions was observed with increased RRS value, suggesting a linear gradient effect. The variables included in the final logistic regression model were the diagnosis of cancer (OR=2.9, p=0.031), pneumonia (OR=2.3, p=0.055), and High MRCI (> 16.5) following discharge (OR=1.9, p=0.119). The cancer diagnosis is positively associated with hospital readmissions of older adults within 30 days

Avaliação do tratamento quimioterápico paliativo com o esquema LDE- paclitaxel em pacientes portadores de metástases ósseas por neoplasia maligna / Evaluation of palliative chemotherapy treatment with the LDEpaclitaxel regimen in patients with bone metastases from malignant neoplas

Introdução: Pacientes com câncer em estádios avançados e metástases ósseas frequentemente não apresentam condições clínicas para a realização de esquemas quimioterápicos convencionais subsequentes, restringindo as opções de tratamento. Anteriormente, demonstramos que nanopartículas artificiais lipídicas (LDE), semelhantes à lipoproteína de baixa densidade (LDL) rica em colesterol, são captadas por tecidos malignos, e quando associadas aos quimioterápicos, após injeção pela via endovenosa, reduz drasticamente a toxicidade do tratamento. Os objetivos deste presente estudo foram avaliar a resposta clínica ao tratamento quimioterápico com paclitaxel (PTX) associado à LDE; avaliar as toxicidades clínicas e laboratorial, e a capacidade da associação LDE-PTX em reduzir a dor oncológica relacionada às metástases ósseas em pacientes com carcinoma de mama, próstata e pulmão, previamente tratados e não elegíveis para tratamento quimioterápico convencional subsequente. Métodos: Dezoito pacientes (8 com câncer de mama, 5 de próstata e 5 de pulmão) com metástases ósseas foram incluídos. O tratamento consistiu no esquema LDE-PTX na dose convencional do PTX (175 mg/m2 de superfície corpórea de 3/3 semanas) e os pacientes foram avaliados por resposta clínica, redução da dor óssea, uso de medicamentos opióides, e ocorrência de fraturas ósseas patológicas. Resultados: No total, 104 ciclos de quimioterapia foram realizados, e nenhum paciente apresentou toxicidade clínica, laboratorial, assim como não houve fraturas patológicas. Dos 18 pacientes incluídos, 9 tiveram sobrevida livre de progressão de doença 6 meses. Houve em todos os pacientes redução da dor óssea, permitindo substituição da medicação opióide por analgésico não opióide. Conclusão: A melhora significativa na dor óssea sem que tenha ocorrido toxicidade do tratamento, e o tempo de não progressão de doença 6 meses na metade dos pacientes sugere que esses pacientes tenham se beneficiado consistentemente do tratamento com a LDE-PTX. Portanto, a LDE-PTX pode tornar- se uma opção terapêutica interessante em pacientes com carcinomas de próstata, mama ou pulmão em estágios avançados e sem condições clínicas de se submeterem a outros esquemas quimioterápicos convencionais

Introduction: Patients with advanced cancer and bone metastases usually do not have clinical conditions to perform additional conventional chemotherapy regimens, restricting treatment options. Previously, we showed that lipid core nanoparticles (LDE), similar to cholesterol-rich low-density lipoprotein (LDL), are taken up by malignant tissues, and when associated to chemotherapy, after endovenous injection, it drastically decreases the toxicity of the treatment. The objectives of this study were to evaluate the clinical response to chemotherapy treatment with paclitaxel (PTX) associated with LDE; to evaluate the clinical and laboratorial toxicities, and the ability of the LDE-PTX to reduce cancer pain related to bone metastases in patients with breast, prostate or lung carcinoma, previously treated and not eligible for subsequent conventional chemotherapy treatment. Methods: Eighteen patients (8 with breast cancer, 5 with prostate and 5 with lung) with bone metastases were included. Treatment consisted of the LDE-PTX regimen at a conventional dose of PTX (175 mg/m2 body surface area, 3/3 weeks) and patients were evaluated for clinical response, reduction in bone pain, use of opioid medications, and the occurrence of pathological bone fractures. Results: In total, 104 chemotherapy cycles were performed, and none of the patients showed clinical or laboratorial toxicities, as well as there were no pathological fractures. Of the 18 patients evaluated, 9 had progression-fee survival 6 months. Patients had decrease in bone pain allowing replacement of opioid medication by another non-opioid analgesic. Conclusion: Significant improvement in bone pain without treatment toxicity, and time to disease progression of 6 months in half of the patients suggest that these patients have consistently benefited with LDE-PTX treatment. Therefore, LDE-PTX may become an interesting therapeutic option in patients with advanced stage of prostate, breast or lung carcinomas and without clinical conditions to undergo other conventional chemotherapy regimens

Development and validation of a reversed-phase HPLC method for quantification of 1'-acetoxychavicol acetate content in a nanostructured lipid carrier formulation

Abstract 1'-acetoxychavicol acetate (ACA)-loaded nanostructured lipid carriers (NLCs) were formulated for prostate cancer therapy and to determine the optimal therapeutic dose, we developed a rapid, specific, and accurate reversed-phase high-performance liquid chromatography (RP-HPLC) method to quantify the ACA content in NLCs. The method was validated according to International Council for Harmonisation of Technical Requirements for Pharmaceuticals for Human Use (ICH) guidelines. Chromatographic separation of ACA from the lipid components was performed with an Agilent 1220 Infinity LC system and ultraviolet detector using an Agilent Poroshell C18 column (4.6 x 250.0 mm). The mobile phase consisted of acetonitrile and water (80:20 [v/v]) with a flow rate of 0.8 mL/min in isocratic mode. Linearity of the standard curve was assessed at an ACA concentration range of 5-200 µg/mL, and a 1/x weighted linear regression was adopted for the calibration curve. The calculated limits of detection and quantification were 0.59 µg/mL and 1.79 µg/mL, respectively. The mean percent recovery of ACA was 100.02% (relative SD, 2%), and the coefficients of variation for intraday and interday assays were within the values required by the ICH. We also demonstrated robustness of the method by altering the mobile phase ratio and flow rate. Furthermore, we proved specificity of the method for ACA by comparing chromatograms of the blank NLC and ACA-NLC. Hence, we effectively used this validated method to determine the drug-loading capacity and entrapment efficiency of the NLCs.

Planejamento, síntese e avaliação biológica de candidatos a fármacos: busca de inibidores epigenéticos da Sirtuína 2 Sir2 / Design, synthesis and biological evaluation of drug candidates: search for Sirtuin 2 (Sir 2) epigenetic inhibitors

As doenças negligenciadas são causadas por agentes infecciosos e parasitários, como vírus, bactérias, protozoários e helmintos. Essas doenças são prevalentes em populações de baixa renda que vivem em países em desenvolvimento e são responsáveis por incapacitar e levar milhares de pessoas à morte. Este nome se dá pois, apesar de sua grande relevância médica, recebem pouca atenção dos governos e indústrias farmacêuticas. Dentre essas doenças podemos destacar a Doença de Chagas, doença infecciosa causada pelo parasita hemoflagelado Trypanosoma cruzi. Endêmica em 21 países, com 6 a 7 milhões de pessoas infectadas resultando em 7500 mortes por ano. A quimioterapia disponível contra essa parasitose é baseada em apenas dois medicamentos, o benznidazol e o nifurtimox, ativos principalmente na fase aguda da doença e com efeitos adversos graves que comprometem a adesão ao tratamento e, além disso, apesar dos enormes esforços na pesquisa de novos agentes antichagásicos em nível nacional e internacional, na maioria realizada academicamente, ainda não foram encontradas alternativas terapêuticas para a doença, persistindo, assim, a necessidade de descoberta e desenvolvimento de novos fármacos. O início de um planejamento de um novo fármaco se dá pela definição de um alvo bioquímico a ser utilizado na busca de moléculas que possam exercer a função de inibidores ou moduladores, conforme a atividade biológica desejada. Neste sentido, as sirtuínas 2 (Sir2) são enzimas que se mostraram essenciais para o crescimento in vitro do T. cruzi em suas formas amastigota e epimastigota. No caso de tripanossomatídeos, em geral, a superexpressão de Sir2 está relacionada à sobrevivência de formas amastigotas. Assim, essas evidências indicam que a Sir2 de tripanosomatídeos tem grande potencial como alvo biológico na busca e desenvolvimento de novos fármacos antichagásicos. O objetivo principal deste projeto foi identificar moléculas que apresentaram atividade inibitória para a sirtuína 2 de T. cruzi por meio da utilização da estratégia de Planejamento de Fármacos Baseada no Ligante - Ligand Based Drug Design (LBDD) e o desenvolvimento de análogos dos inibidores da Sir2. A modificação molecular está entre algumas das técnicas tradicionais usadas no desenvolvimento racional de um fármaco, e é usada principalmente no desenvolvimento de análogos, e busca melhorar as propriedades farmacocinéticas e/ou farmacodinâmicas de um protótipo, obter propriedades de interação semelhantes ao alvo e, em alguns casos, revelar uma atividade biológica. Com este intuito, análogos do sirtinol e da salermida foram sintetizados e uma nova rota sintética utilizando o microrreator em fluxo contínuo foi desenvolvida e apresentou rendimento superior quando comparado à síntese em bancada. A partir desta metodologia foram obtidos 20 compostos. Os ensaios in vitro contra formas amastigotas do T. cruzi indicaram que 8 compostos inibiram a atividade parasitária em mais de 50%, na dose de 10 µM, sendo que alguns destes apresentaram maior inibição parasitária quando comparados ao benznidazol, o fármaco de referência e único disponível no Brasil. Com estes resultados preliminares, novos ensaios estão sendo realizados para identificar potência e mecanismo de ação destes candidatos a agentes tripanomicidas

Neglected diseases are caused by infectious and parasitic agents such as viruses, bacteria, protozoa and helminths. These diseases are prevalent in low-income populations living in developing countries and are responsible for disabling and killing thousands of people. They get this name because, despite their great medical relevance, they end up receiving little attention from governments and pharmaceutical industries. Among these diseases, we can highlight Chagas disease, an infectious endemic disease caused by the hemoflagellate parasite Trypanosoma cruzi. This disease is endemic in 21 countries, with 6 to 7 million people infected resulting in 7,500 deaths per year. Chemotherapy is based on just two drugs, benznidazole and nifurtimox, which are mainly active in the acute phase of the disease. These drugs have adverse effects that compromise adherence, even more, considering that they are not effective from the point of view of the chronic phase of the disease. Despite the enormous efforts in researching new anti-chagasic agents at the national and international level, and mostly carried out academically, therapeutic alternatives for the disease have not yet been found, thus, the need for the discovery and development of new drugs persists. Sirtuins 2 (Sir2) are enzymes that have been shown to be essential for the in vitro growth of T. cruzi in its amastigote and epimastigote forms. In the case of trypanosomatids in general, Sir2 overexpression is related to the survival of amastigote forms. Sir2 inhibitors, such as sirtinol, have shown efficacy in leishmanicides. Thus, these evidences indicate that Sir2 from trypanosomatids can be considered as a biological target in the search and development of new anti-chagasic drugs. The beginning of a new drug planning study is the definition of a biochemical target to be used in the search for molecules that can play the role of inhibitors or modulators, according to the desired biological activity. The main objective of this project was to identify molecules that presented inhibitory activity to sirtuin 2 of T. cruzi using the Ligand Based Drug Design (LBDD) strategy of planning and the development of analogues of Sir2 inhibitors. Molecular modification is a traditional technique used in the rational development of a drug, as well as the use of natural products, combinatorial chemistry, high-throughput screening (HTS), among others. Mainly used in the development of analogues, molecular modification is applied for different purposes, among them, it seeks to improve the pharmacokinetic and/or pharmacodynamic properties of a prototype, obtain target-like interaction properties and, in some cases, reveal an activity biological. For this purpose, analogues of sirtinol and salermide were synthesized and a new synthetic route using the microreactor in continuous flow was developed and presented superior yield when compared to benchtop synthesis. From this methodology, 20 compounds were obtained. in vitro assays against amastigote forms of T. cruzi indicated that 8 compounds inhibited parasitic activity by more than 50% at a dose of 10 µM, and some of these showed greater parasitic inhibition when compared to benznidazole, the reference drug, and only available in Brazil. With these preliminary results, new assays are being carried out to identify the potency and mechanism of action of these candidate trypanocidal agents

Desenvolvimento de inibidores duais de histona desacetilase 6 (HDAC6) e tirosina quinase (TQ) com vistas ao tratamento do câncer / Design of histone deacetylase 6 (HDAC6) and tyrosine kinase (TK) dual inhibitors for cancer treatment

Câncer é a denominação atribuída a um conjunto de doenças que são responsáveis pela segunda maior causa de morte no Brasil e no mundo. A quimioterapia figura entre uma das estratégias utilizadas para o tratamento e cura do câncer, sendo amplamente empregada em estratégias terapêuticas isoladas, ou em associação à radioterapia e cirurgia. A enzima histona desacetilase 6 (HDAC6) é responsável por desacetilar a cadeia lateral de N-acetillisinas em -tubulinas, desempanhando papel crítico na dinâmica do citoesqueleto celular, estando superexpressa em uma série de neoplasias. Neste sentido, na última década os receptores tirosina quinase (TQ) foram os principais alvos de fármacos aprovados para o tratamento do câncer e de doenças autoimunes e continuam atraindo a atenção de grupos de pesquisa dada a exorbitante diversidade do quinoma humano. É sabido que a monoterapia seja com inibidores de HDAC, seja com inibidores TQ, apresenta problemas de toxicidade, reações adversas, ineficácia, resistência e/ou recidiva. Diversos estudos relatam o desenvolvimento de inibidores duais de HDAC-TQ, almejando tanto a simplificação do tratamento, quanto sinergismo terapêutico e redução de efeitos adversos. Assim, o presente trabalho apresenta o planejamento, síntese e avaliação da citotoxicidade de inibidores duais, potencialmente seletivos para HDAC6 e receptores TQ. No total, 23 compostos foram sintetizados entre 2 a 4 etapas. Todos os compostos finais foram caracterizados por RMN (1H e 13C) e espectrometria de massas de alta resolução (HRMS). A citotoxicidade foi determinada pelo ensaio de MTT, em linhagens derivadas de tumores sólidos (HCT116 e MCF-7) e hematológicos (Jurkat e Namalwa). Os compostos apresentaram citotoxicidade em concentrações micro e nanomolares em todas as linhagens testadas, sendo que a linhagem MCF-7 foi a mais resistente à ação dos compostos, e as linhagens hematológicas foram as mais sensíveis. Os inibidores 4d-f foram os mais ativos na triagem por MTT, com IC50 iguais a 20, 30 e 50 nM, respectivamente, em células Jurkat. Estudos mecanísticos do efeito citotóxico indicaram que os compostos 4d-f exercem atividade de forma tempo-dependente, e majoritariamente por ação antiproliferativa, embora estímulos apoptóticos também tenham sido observados nos estudos. Simulações de ancoramento molecular (docking) e de relação entre as estruturas químicas dos compostos e suas respectivas atividades biológicas (REA) permitiram identificar padrões moleculares, propriedades físico-químicas e eletrônicas que potencialmente possuem relação com a atividade biológica dos compostos, permitindo futuras otimizações do arcabouço molecular desta série de compostos. Tomados em conjunto, os resultados deste trabalho revelam o potencial terapêutico de inibidores duais de HDAC6-TQ. Notadamente, os compostos apresentados aqui podem ser os primeiros potenciais inibidores duais de HDAC6-TQ a serem reportados na literatura

Cancer is the name of a series of diseases that are the second main cause of death in Brazil and worldwide. Chemotherapy is one of the main strategies to treat and cure cancer, and has been widely applied as a single therapeutic agent, and in association with radiotherapy and surgery. Histone deacetylase 6 (HDAC6) deacetylates N-acetyllysine side chains of tubulin, playing crucial role on cytoskeletal dynamics, and could be overexpressed in several cancers. Tyrosine kinase receptors (TK) have been the main targets of FDA-approved drugs through the last decade for both cancer and autoimmune diseases, and have been attracting special attention of research groups due to the exorbitant diversity of the human kinome. It is known that either HDAC or TK single therapy have toxicity issues, adverse effects, inefficacy, resistance and/or recidive. Therefore, many studies report the design of HDAC-TK dual inhibitors aiming simpler treatments, synergism of action and side effects reduction. Herein, the design, synthesis and cytotoxic evaluation of dual and selective HDAC6-TK inhibitors are presented. A total of 23 compounds were designed and synthesized through 2 to 4 steps. All final compounds were characterized by 1H/13C NMR and high-resolution mass spectrometry (HRMS). The cytotoxicity of compounds was determined by MTT assay for both solid (HCT116 and MCF-7 cells) and hematological cancers (Jurkat and Namalwa cells). Compounds exhibited micro and nanomolar ranges of cytotoxicity for all cell lines tested. MCF-7 cells were the most resistant against the treatment, and hematological cells were more susceptible to the cytotoxic effect of the compounds. Compounds 4d-f were the most actives in the MTT screening against Jurkat cells (IC50 = 20, 30 and 50 nM, respectively). Mechanistic studies regarding the cytotoxic effects of 4d-f indicated that the compounds induced cell death in a time-dependent manner mainly via cytostatic activity even though apoptotic stimuli were observed also. Molecular docking and structure-activity relationships (SARs) allowed the identification of molecular patterns, and physicochemical and electronic properties that potentially modulate the biological activity of these compounds, allowing further optimizations of the molecular scaffold for these series of compounds. Taken together, the results of this study reveal the therapeutic potential of HDAC6-TK dual inhibitors. Noteworthy, the compounds reported herein could be the first HDAC6-TK dual inhibitors ever reported in literature

Profile of pharmaceutical interventions of a pharmacotherapeutic follow-up model for diabetic patients in a community pharmacy

Abstract The insertion of Pharmaceutical Care in Primary Health Care (PHC) improves patients' clinical outcomes and quality of life. Pharmacotherapeutic follow-up can contribute to the management of chronic diseases such as diabetes, promoting better glycemic control and adherence to therapy. This study aimed to assess the Drug-therapy Problems (DTPs) and Pharmacist Interventions (PIs) on the pharmacotherapeutic management in patients with type 2 diabetes mellitus (T2DM) in a community pharmacy. A quantitative, retrospective, and cross-sectional study was conducted in a Pharmaceutical Care Program within the PHC in Juiz de Fora (Minas Gerais, Brazil). Inclusion criteria were patients with T2DM above 18, who attended at least three pharmaceutical consultations between July 2016 and October 2018 and presented two or more glycated hemoglobin tests. The study group (n = 17) was largely composed of women (65%), elderly (76%), sedentary (72%), and obese people (52%). The resolution was achieved in 79% of the DTPs identified (n = 115). Most of DTPs were related to administration and adherence to pharmacotherapy (46%). 60% of the 437 PIs involved the provision of information and counseling. In other words, accessible interventions lead to high resolvability. Therefore, clinical actuation of pharmacists could improve the prognosis in diabetes treatment

Cost analysis of a medication dispensing service in community pharmacy in Brazil

This study was aimed to calculate in detail the costs of a medication dispensing service in community pharmacy in Brazil. Descriptive and retrospective analysis with a cost analysis based on mixed costing; absorption costing and time-driven activity based-costing, considering year 2018 and both public and private health system perspectives within a one-year time horizon to estimates costs related to implement and to deploy the service, costs per patient and costs per activity of process (US$ 1 = R$ 3.8310 in October, 2018). Total costs of dispensing service ranged from US$ 24,451.61 to US$ 37,914.48. Costs per patient ranged from US$ 2.43 to US$ 3.77. Costs per activity of the process ranged from US$ 0.39 in pharmacotherapy assessment to US$ 2.46 in pharmaceutical interview. This provides evidence to deploy and implement a structured medication dispensing service in community pharmacy in Brazil with a view to optimize the usage of medicines.

Schizophrenia: effects of aripiprazole in metabolic syndrome

Schizophrenia, in general, is characterized by severe and disabling mental alterations, characterized by the impairment of one's mental, behavioral and social activities, developing certain clinical symptoms, relevant to the diagnosis. The drugs used for the reversion of the symptoms cause several adverse effects that affect the patient's health and well-being, such as motor, endocrine and cardiovascular damages. For a long time, little was known about the origin and the treatment of schizophrenia, which has become a curiosity for science, originating countless researches and theories that are background for several treatments. It is known that alterations in dopaminergic pathways are related to the development of the symptoms of the disease, and evaluating these symptoms, the diagnosis is made and the treatment is initiated. The insertion of new drugs with different characteristics and mechanisms tends to be an advance in the treatment of schizophrenia, as well as reducing the occurence of adverse effects or not worsening already existing cases. Aripiprazole is an innovative atypical antipsychotic employed in the pharmacotherapy of schizophrenia, which tends to attenuate the symptoms, inducing few adverse effects compared to other drugs that are already used, and promotes better quality of life to patients.

Desenvolvimento e validação de indicadores para avaliação da qualidade do acompanhamento farmacoterapêutico / Development and validation of indicators for quality assessment of medication management

Um dos elementos para melhoria da qualidade dos serviços farmacêuticos clínicos é medir a qualidade do cuidado prestado e os indicadores podem ser usados nesta avaliação. O presente trabalho teve como objetivos identificar estudos sobre indicadores de qualidade para serviços farmacêuticos clínicos e desenvolver e validar um instrumento de indicadores para avaliação dos serviços de acompanhamento farmacoterapêutico prestados para pacientes ambulatoriais. Para tanto, uma busca abrangente da literatura foi conduzida nas bases de dados PubMed/Medline, Scopus, Lilacs e DOAJ por esses estudos. Os instrumentos apresentados pelos estudos foram avaliados em relação à qualidade das propriedades psicométricas. A seguir, foi desenvolvido um instrumento de indicadores-chave de desempenho. O grupo de pesquisa estabeleceu sete indicadores possíveis para avaliação de especialistas da área através de duas rodadas da técnica Delphi para validação de conteúdo. Ainda, farmacêuticos foram convidados a participar por meio de um questionário para validação de construto e confiabilidade do instrumento. A busca bibliográfica identificou 3.276 registros, dos quais 12 estudos completaram os critérios de inclusão. No geral, o maior número de estudos foi baseado em pesquisas para avaliar a satisfação dos pacientes e usou a revisão da literatura combinada com opinião de especialistas para o desenvolvimento do instrumento. Todos os estudos apresentaram algumas propriedades psicométricas do instrumento. A consistência interna e a validade de conteúdo foram os critérios mais relatados dos estudos, e nenhum deles apresentou o critério de estabilidade. Onze (68,8%) especialistas participaram da primeira rodada da técnica Delphi e nove (81,8%) especialistas completaram as 2 rodadas. Um novo indicador foi desenvolvido após a avaliação do painel de especialistas na primeira rodada. No geral, a validade de conteúdo e construto foi alcançada para o instrumento final. Os resultados desta tese apontam que os instrumentos dos estudos identificados na revisão sistemática apresentaram propriedades psicométricas, porém de forma incompleta ou não satisfatória. Ainda, um instrumento com seis indicadores foi desenvolvido e validado para o Serviço de Acompanhamento Farmacoterapêutico prestado para pacientes ambulatoriais

One of the elements of quality improvement of medication management services is measuring the quality of care and key performance indicators (KPIs) can be used in this assessment. The study is aimed to identify quality indicators instruments in pharmaceutical care services and to develop and validate KPI instrument for medication management services provided for outpatients. For this, comprehensive literature search was performed in databases PubMed/Medline, Scopus, and Lilacs. The psychometric quality of the instruments was determined. In addition, a key performance indicators instrument was developed. A working group established 7 possible KPIs for assessment of the expert panel through an internet based 2-round Delphi approach. An internet questionnaire was developed for pharmacists in order to construct validity and reliability of the instrument. The literature search yielded 3,276 records, of which 12 studies satisfied the inclusion criteria. Overall, the greatest number of studies were based surveys to assess patients' satisfaction and used literature review combined with expert's opinion for the instrument development. All studies presented some psychometrics properties of the instrument. Internal consistency and content validity were the most reported criteria of the studies and none of them presented stability. Eleven (68.8%) experts participated in the Delphi round 1 and nine (81.8%) experts completed the 2 Delphi rounds. A new KPI was develop after expert panel assessment in the first round. Overall, content and construct validity were reached for final instrument. The results of this thesis point out that instrument of the studies identified in the systematic review presented some psychometrics properties, but did not describe them satisfactorily. In addition, a set of six key performance indicators was developed and validated for medication management services provided for outpatients

Supervivencia de cáncer gástrico en el occidente de Honduras, estudio piloto: 2002-2012 / Survival of Gastric Cancer in Western Honduras Pilot study: 2002-2012

Antecedentes: El cáncer gástrico es la segunda causa de muerte por cáncer globalmente. En Honduras la incidencia en la década pasada fue de 39 y 21 por 100,000 habitantes para hombres y mujeres, respectivamente. En 2008 IARC (GLOBOCAN) colocó a Honduras como el país con más alta incidencia de cáncer gástrico en Latinoamérica. Objetivo: Determinar la supervivencia en pacientes diagnosticados con cáncer gástrico en el occidente de Honduras entre los años 2002-2012. Métodos: Se diseñó un es- tudio de cohorte retrospectivo de pacientes diagnosticados con cáncer gástrico en el Hospital de Occidente (2002-2012). Una muestra de 144 pacientes fue seleccionada de un total de 490 para obtener un nivel de confianza de 95%. La recolección de datos se obtuvo mediante autopsia verbal. Se analizaron los factores pronósticos de supervivencia mediante modelos de razón de riesgos proporcio - nales de Cox (CI:95%) Resultados: La relación hombre/mujer fue 2.8:1. La media de edad fue 63.29 años. La supervivencia global a cinco años fue 9.39%. Entre los pacientes que recibieron terapia dual (cirugía y quimioterapia), se encontró un aumento estadísti- camente significativo de la supervivencia (10.42%,p=0.048). Entre la localizaci ón proximal (28.95%) y distal (56.58%) se observó diferencia estadísticamente significativa (p=0.03). No hubo diferencia estadísticamente significativa entre hallazgos macroscópicos (Borrmann) y microscópicos (Lauren). Discusión: Este estudio representa el primer esfuerzo para estimar la supervivencia de cáncer gástrico en Honduras. La supervivencia podría estar ligada a la localización de la lesión primaria y al tipo de tratamiento. Se espera desarrollar estudios con mayor cobertura, para responder a estas preguntas...(AU)

Evaluacioón de dos protocolos de quimioterapia (EBV-1 y EBV-2) más radioterapia en niños con enfermedad de hodgkin / Evaluation of two chemoterapy of protocolic (EBV-1 And EBV-2) more children in radioterapy with hodgkin desease

Se presentan los resultados obtenidos en 46 niños tratados en la unidad de linfomas del Hospital Universitario de Caracas con el esquema EBV más Rt a bajas dosis. Veinticuatro se trataron entre enero 1988-diciembre de 1990 con el EBV-1 (epirubicina 30 mg/m² yviblastina 6 mg/m² los días 1 y 15, cada 4 semanas) yveintidós se trataron entre enero 1991-diciembre 1994 con el EBV-2, cuya diferencia con el anterior fue el incremento de las dosis de epirubicina a 6o mg/m²Las características clínicas e histológicas de los grupos fueron similares. Se consideraron factores pronósticos (FP): los estadios clínicos III Y IV, la masa medistinal mayor del 30 por ciento del diámetro torácico, los síntomas B y el volumen tumoral mayor de 5 cm. Los pacientes con 0 ó 1 FP se ubicaron en el grupo favorable y recibieron 4 ciclos de Qt, combinados en ambos grupos con Rt: 20-25 C y a zonas afectas. Se obtuvo remisión completa en el 76 por ciento de los pacientes y sobrevidas libre de enfermedad, libre de eventos y total de 84 por ciento, 68 por ciento y 78 por ciento respectivamente a los 5 años de seguimiento. No se observaron diferencais significativas en los resultados obtenidos con el EBV-1 y el EBV-2, pero fueron superiores en el grupo favorable. La Qt fue bien tolerada y pudo administrarse ambulatoriamente. Los efectos tóxicos tardíos fueron hipotiroidismo subclínico en 5/14 pacientes (36 por ciento), carcinoma de tiroides en 1/46 (2 por ciento) y cardiomiopatía dilatada en 1/46 (2 por ciento) tratado con EBV-2. Concluimos que 4 ciclos de EBV-1 combinados con Rt. a bajas dosis es una alternativa efectiva en el tratamiento de los niños con E.H grupo favorable y que el incremento de la dosis de epirubicina a 60 mg/m² no mejora los resultados

Drug consumption pattern in low socio-economic group in an urban community.

117 families, having a total population of 558 were studied regarding drug consumption pattern. It was found that the average no. of episodes per person was 0.99 of which drugs were consumed for 72% of episodes. Significant difference was observed in consumption of drugs between males and females. Allopathic medicines were consumed for 93.3% of the episodes and the major source (53.8%) of medical care was from private practitioners. It was seen that the number of drugs consumed per episode of sickness rose as the per capita income increased. Vitamins and Minerals (22.3%) were the main group of drugs consumed. Drugs acting on the alimentary system (17.5%), Respiratory System (14.7%), Antimicrobials (14.6%) and Analgesics (10.8%) contributed to 80% of drug intake.
