Traditional Chinese medicines(TCMs) have certain limitations in the clinical research design in their post-marketing evaluation, so that randomized controlled programs cannot be strictly implemented in some studies, while the objective performance criteria is a reasonable external controlled research method that has been gradually recognized at home and abroad in recent years in addition to randomized controlled trial(RCT) method. It is more mature in medical devices, surgery and other research fields, but there is no relevant report in the field of post-marketing evaluation of Chinese patent medicines. In this paper, the application prospect of the objective performance criteria and the problems were discussed in the field of post-marketing evaluation of TCM. The characteristics of as TCM are more consistent with the scope of the objective performance criteria, the application of the objective performance criteria in post-marketing evaluation of Chinese patent medicines, especially in single arm research, can break through the limitations of existing conventional clinical research methods, and improve the level of evidence, with good feasibility and advantages. However, in the application process, we should pay attention to the key issues such as the selection of index, research population, follow-up period and the reference selection, to ensure the quality of research. This research group has carried out some exploration and practice in the field of post-marketing evaluation of TCM injections by using single arm combined with the objective performance criteria, hoping to establish the key technology in this field, and provide certain research and design reference for the secondary development of Chinese patent medicines.

Objective: to analyze the contribution of patients in drug surveillance, considering some stages of development of these technologies and the interest of public health. Methodology: a bibliographic and documentary analysis was performed on patients' contributions and mechanisms of social participation. Results: we identified consolidated initiatives and results that support the importance of patients in drug surveillance in various segments. However, participation is limited due to the low scientific literacy and ineffectiveness of some social participation mechanisms. Conclusion: patient representative organizations can contribute more effectively to social participation initiatives in drug surveillance, as reported in international experiences. In addition, it is essential that regulatory agencies seek to improve participation mechanisms and the use of methods to collect social contributions, as well as to systematize patients' experiences.

In 2013,China pharmaceutical regulatory department issued guiduance on postmarketing drug safety monitoring for industry. It aimed to encourage industry to carry out postmarketing drug safety monitoring including hospital-based intensive monitoring of postmarketing Chinese patent medicine. Subsequently,more and more such kind of studies have been performed all over China. However,in view of the current situation in this field,the development of hospital-based intensive monitoring of postmarketing Chinese patent medicine lacks standardization,such as unreasonable design,omission of reports about adverse drug reactions,inadequate process of quality control,non-standardized interpretation of adverse reactions,etc. Therefore,it is necessary to formulate relevant technical specifications to guide this area. The developing of this technical specification refered to the international post-marketing safety monitoring model and advanced design concepts and methods. We developed it under the guidance of relevant laws,regulations and technical documents in China. Meanwhile the characteristics of Chinese patent medicines and the real situation in this area were considered. The aim of this technical specification is to obtain the incidence,type,degree and clinical manifestation of adverse drug reactions of Chinese patent medicines,to find new risk signals of adverse reactions,to identify risk factors,and to provide a basis for the formulation of risk management and control plans. This specification has been approved by China association of Chinese medicine which is numbered T/CACM011-2016.

RESUMEN La giardiasis es una enfermedad causada por Giardia duodenalis, protozoario enteropatógeno que también es responsable de la enfermedad diarreica aguda y la gastroenteritis en humanos. Dadas las características de excreción intermitente propias de este parásito, la probabilidad de obtener resultados falsos negativos durante el proceso de diagnóstico es alta. En el Grupo de Parasitología del Instituto Nacional de Salud de Colombia se identificaron proteínas inmunogénicas presentes en quistes y trofozoítos del parásito en aislamientos colombianos de Giardia con potencial comercial y posibilidad de ser patentadas. Se realizó un estudio exploratorio descriptivo a partir de las características de la técnica en estudio, su estado de desarrollo y la viabilidad comercial de la invención. Se encontraron 390 patentes y se seleccionaron cinco invenciones similares que no representaban ningún riesgo frente a una eventual solicitud de patente. De los 36 estuches para el diagnóstico de Giardia disponibles en el mercado y las 21 licencias sanitarias otorgadas hasta diciembre del 2017, sólo cuatro y tres, respectivamente, proponen técnicas similares a la de la estudiada, pero ninguna de ellas cuenta con un registro de patente relacionado. La técnica en desarrollo es innovadora y puede aplicarse en el campo de la salud pública en la Región de las Américas con beneficios previsibles.

ABSTRACT Giardiasis is a disease caused by Giardia duodenalis, an intestinal protozoan that causes acute diarrhea and gastroenteritis in humans. Given the characteristic intermittent excretion of this parasite, there is a high probability of false negative results during diagnosis. The Parasitology Group of Colombia's National Institute of Health identified immunizing proteins present in the parasite's cysts and trophozoites in Colombian Giardia isolates with commercial and patentability potential. A descriptive exploratory study was conducted that focused on characteristics of the technique under study, its state of development, and the commercial viability of the invention. A total of 390 patents were found and five similar inventions were selected that did not pose any risk regarding an eventual patent application.

Background: The use of herbal medicines is justified empirically using ethnopharmacological knowledge, which has limitations. Reports of adverse events (AE) may contribute for safety, quality, and effectiveness assessment. Objectives: This study aimed to develop an instrument to allow detection and evaluation of the causal likelihood of AE related to herbal medicines. Methods: A quantitative methodological development research intervention was performed with primary care health professionals. Two cases were distributed in an interval of one week in order to allow for completion of the proposal form. The within-rater reliability was calculated and classified into satisfactory, regular, and unsatisfactory, according to essential, necessary, and recommended items reported. Results: Fifty-seven professionals were enrolled. A high degree of the within-rater reliability was observed for the most essential, necessary, and recommended fields. The instrument contributed to assessment of definite causal association, once the duration of reactions including evolution, withdrawal, and reposition items showed high reliability. Most fields poor and weak filled were related to quality defects, such as popular name and appearance. Conclusions: Data suggest the instrument is adequate to report AE arising from herbal medicines. Owing to information regarding to organoleptic characteristics, the instrument is different from drug instruments. Therefore, it is intended to improve AE reports related to herbal medicines and contribute for appropriate use.

Antecedentes: Hierbas medicinales son utilizadas empíricamente con la base en el conocimiento etnofarmacobotánico, los cuales tienen limitaciones. Los informes de los eventos adversos (EA) pueden contribuir a la seguridad, la calidad y la evaluación de la eficacia de estos productos. Objetivos: El objetivo del estudio fue desarrollar un formulario para permitir la detección y evaluación de la probabilidad causal de EA relacionado al uso de plantas medicinales e fitoterápicos. Métodos: Investigación cuantitativa, de desenvolvimiento se llevó a cabo con los profesionales sanitarios de atención primaria. Dos casos fueran distribuidos, en un intervalo de una semana, con el fin de ser llenado en el formulario propuesto. La fiabilidad inter-observadores del instrumento fue evaluada y los resultados fueran clasificados en satisfactorio, regular e insatisfactorio, según los datos esenciales, necesarios y recomendados que fueran rellenados en el formulario de notificación. Resultados: Cincuenta y siete profesionales fueran elegibles. Se observó alto grado de fiabilidad entre observadores para la mayoría de los campos esenciales, necesarios y recomendados. El formulario contribuyó para la evaluación de la asociación causal definitiva, una vez que los campos de duración de las reacciones; evolución, retirada y re- exposición tuvieran alta fiabilidad. La mayoría de los campos flacamente llenados estaban relacionados con defectos de calidad, tales como: nombre popular y apariencia. Conclusiones: Los datos sugieren que el formulario propuesto es adecuado para reportar EA derivados de hierbas medicinales. Por la información relativa a las características organolépticas, el instrumento es diferente de lo instrumento para notificación de medicamentos. Por lo tanto, se pretende mejorar los informes de EA relacionados con los productos naturales y contribuir para el uso apropiado.

The issue of safety evaluation on postmarketing Chinese medicines has become a hot topic in mainland China recently. Researchers and decision-makers can obtain a variety of evidence resources about safety in order to evaluate the safety profile for postmarketing Chinese medicines. A registry study on ten Chinese medicine injections for postmarketing surveillance has come to the end. From such a study observing more than 300,000 patients for more than 4 years, a theoretical research question emerges, that is, how to identify and evaluate safety evidence systematically. We put forward a brand new research paradigm on the theory level, which is to establish a body of evidence on safety evaluation for postmarketing Chinese medicine. Therefore, multiple information sources were explored and extracted from preclinical experiments for toxicity, postmarketing clinical trials for effificacy and safety evaluation, registry study for surveillance, retrospective data analysis from hospital information system and spontaneous response system, and case reports and systematic review from literature. Greater efforts for this idea and cooperation with experts in this fifield both in China and abroad are urgently needed.

The animal trade is an important risk factor that affects the spread of diseases among animals and herds. The goal of the present study was to characterize the cattle movement network in Pernambuco, Brazil, based on the animal movement permits (Guias de Trânsito Animal; GTAs) from 2012 to 2013, and identify the intensity of the commercial relationship between farm premises. A total of 737,950 GTAs were issued, and the movement of 3,481,185 cattle (1,688,585 in 2012 and 1,792,600 in 2013) was analyzed. Of the moved animals analyzed, 52.57% (1,829,907/3,481,185) were involved in the movement of cattle in or out of livestock markets, indicating that livestock markets played a major role in the network. Approximately 20% of the more-connected premises were responsible for approximately 87% of the movement related to sales and 95% of the movement related to purchases. Considering the important role of livestock markets and the intense cattle trade between farm premises, surveillance, and control measures could be more efficient if targeted to livestock markets and highly connected premises to prevent the spread of infectious diseases.(AU)

O comércio de animais é um importante fator de risco para a disseminação de doenças entre animais e rebanhos. O objetivo do presente estudo foi caracterizar a rede de movimentação de bovinos em Pernambuco, com base nas guias de trânsito animal (GTAs) de 2012 a 2013, e identificar a intensidade da relação comercial entre os estabelecimentos. Foram analisadas 737.950 GTAs emitidas, e as movimentações de bovinos totalizaram 3.481.185 animais (1.688.585 em 2012 e 1.792.600 em 2013). Um percentual de 52,57% (1.829.907/3.481.185) das movimentações de bovinos envolveu entrada ou saída de feiras de gado, indicando que as feiras desempenharam um papel importante na rede. Aproximadamente 20% dos estabelecimentos mais conectados foram responsáveis por aproximadamente 87% das movimentações relacionadas às vendas, e 95% das movimentações, relacionadas às compras. Considerando o importante papel das feiras e o intenso comércio de bovinos entre as propriedades, medidas de vigilância e controle podem ser mais eficientes se aplicadas em feiras e estabelecimentos altamente conectados, para prevenir a propagação de doenças infecciosas.(AU)

A ciência e a tecnologia cada vez mais vêm proporcionando avanços em produtos inovadores. Particularmente na área da saúde nota-se eminente sinergismo entre os materiais utilizados, suas propriedades de biocompatibilidade, biofuncionalidade, processabilidade, esterilidade e a área de aplicabilidade no organismo humano. O setor farmacêutico por apresentar grande complexidade exige conhecimentos multidisciplinares, atualizados e em conformidade às tendências internacionais. A Agência Nacional de Vigilância Sanitária (ANVISA) tem sob sua responsabilidade extensa diversidade de bens, serviços e produtos, dentre eles estão os correlatos, que também compreende os produtos para saúde. Os produtos para saúde são classificados conforme o seu risco, no Brasil podendo apresentar até quatro classes, sendo as classes III e IV as que caracterizam maior risco. Para alguns produtos, devido seu risco sanitário, é compulsório a Certificação de Conformidade pelo Instituto Nacional de Metrologia, Qualidade e Tecnologia (INMETRO) previamente a concessão de seu registro sanitário pela ANVISA. Dentre as normas técnicas aplicáveis pelo INMETRO estão as normas da Associação Brasileira de Normas Técnicas (ABNT) e na sua ausência, as normas da International Organization for Standardization (ISO). Outros requisitos técnicos e regulatórios devem ser contemplados com o propósito de comprovação da segurança e eficácia dos produtos. Entretanto, as regulamentações sanitárias inerentes a essa categoria de produtos ainda se encontram incipientes no país. A desenvoltura do setor produtivo nesse segmento pode ser evidenciada pelo aumento de novas solicitações na ANVISA e de seu crescimento na balança comercial. No entanto, observa-se pouco estudo e entendimento do setor regulado e regulador referente à relação mútua entre ANVISA, INMETRO e ABNT e quanto à regulação sanitária aplicável para obtenção da anuência do produto ao consumo. Na conjuntura das demandas apontadas o objetivo deste estudo foi avaliar o processo regulatório aplicável à cadeia produtiva dos produtos para saúde com a finalidade de compreender a relação entre ANVISA, INMETRO e ABNT na garantia da qualidade, segurança e eficácia dos produtos. A metodologia aplicada neste trabalho foi à pesquisa qualitativa. Com o auxílio da pesquisa documental constatou-se que o processo regulatório brasileiro é complexo, específico e robusto e apresenta estrutura e exigências semelhantes dos Estados Unidos e União Europeia. A fiscalização pós-uso é uma tendência internacional e a ANVISA vem adotando com frequência com intuito de acompanhar a qualidade dos produtos comercializados. As três instituições apresentam competências definidas e regulamentadas, bem como mecanismos de inter-relação por meio de conselhos consultivos. O estudo de caso caracterizou que o perfil dos profissionais do setor regulado apresenta em grande percentual formação na área da saúde e nível de pós-graduação, porém o nível de conhecimento dos principais conceitos relativos aos produtos para saúde é parcial, reforçando a necessidade de incentivos de capacitação de recursos humanos em regulação em saúde

The science and technology increasingly been providing advancements in innovative products. Particularly in the health score is eminent synergism between the materials used, their properties of biocompatibility, biofunctionality, processability, sterility and applicability area of the human body. The pharmaceutical sector to present great complexity requires multidisciplinary knowledge, up to date and in line with international trends. The National Health Surveillance Agency (ANVISA) has under its responsibility extensive range of goods, services and products, among them are correlates, which also includes medical devices. Medical devices are classified according to their risk in Brazil may present up to four classes, and classes III and IV which characterize the greatest risk. For some products, because of their health risk, it is compulsory Compliance Certification by the National Institute of Metrology, Quality and Technology (INMETRO) prior to granting its sanitary registry by ANVISA. From among the technical standards the INMETRO are the standards of the Brazilian Association of Technical Standards (ABNT) and in his absence, the standards of the International Organization for Standardization (ISO).Other technical and regulatory requirements must be included for the purpose of proving the safety and efficacy of products. However, the sanitary regulations inherent in this product category is still incipient in the country. The resourcefulness of the productive sector in this segment can be evidenced by the increase in new requests in ANVISA and its growth in the trade balance. However, there is little study and understanding of the regulated and regulatory sector concerning the mutual relationship between ANVISA, INMETRO and ABNT and on the sanitary regulation applicable to obtaining the approval of the product for consumption. In the context of the demands indicated the objective of this study was to evaluate the regulatory procedure applicable to the production chain of medical devices in order to understand the relationship between ANVISA, INMETRO and ABNT in ensuring quality, safety and efficacy of products. The methodology used in this study was the qualitative research. With the assistance of documentary research it was found that the Brazilian regulatory process is complex, specific and robust and has similar structure and requirements of the United States and European Union. The postmarketing monitoring is an international trend and ANVISA has adopted often aiming to monitor the quality of marketed products. The three institutions have defined and regulated competences and interrelation through advisory boards mechanisms. The case study characterized the profile of professionals in the regulated sector has a large percentage of training in health and post-graduate level, but the level of knowledge of the main concepts related to medical devices is partial, reinforcing the need for incentives training of human resources in health regulation

The effective quality control in clinical practices is an effective guarantee for the authenticity and scientificity of the findings. The post-marketing reevaluation for traditional Chinese medicines (TCM) focuses on the efficacy, adverse reaction, combined medication and effective dose of drugs in the market by expanded clinical trials, and requires a larger sample size and a wider range of patients. Therefore, this increases the difficulty of quality control in clinical practices. With the experience in quality control in clinical practices for the post-marketing reevaluation for Kangbingdu oral for cold, researchers in this study reviewed the study purpose, project, scheme design and clinical practice process from an overall point of view, analyzed the study characteristics of the post-marketing reevaluation for TCMs and the quality control risks, designed the quality control contents with quality impacting factors, defined key review contents and summarized the precautions in clinical practices, with the aim to improve the efficiency of quality control of clinical practices. This study can provide reference to clinical units and quality control-related personnel in the post-marketing reevaluation for TCMs.
