Contribution of EQA to improve Preanalytical practices by systematic verification of Laboratory Services
International literature describes the preanalytical phase as the most susceptible to errors due to the numerous non automated activities it involves Most EQA organizers offer preanalytical schemes to participants. There are basically three types of surveys procedures registration, samples circulation and errors registration The Portuguese EQA Programme ( provides these type of schemes for 13 years, using as a guide
the ISO 15189 2012 In order to improve the evaluation of the preanalytical phase, PNAEQ recently launched two other preanalytical EQA schemes, mystery client and presential audits in 2015 and 2016 respectively. The aim of the mystery client survey is to verify whether the information provided to the patient is constant regardless the day and time or if it is dependent on the collaborator. The aim of the presential audit survey is to give the participants a tool to verify if the procedures performed daily are in accordance with laboratorial good practices recommendations. Conclusions:
Results from Mystery Client surveys demonstrate the need for written procedures and harmonization of practices for all collaborators, as more than a third of the responses differed in date/time and operator in a global view. In the Presential Audit surveys we highlight as critical points the results regarding questions 3 5 and 6 as they point to specific problems that occurred during the blood collection procedure, such as operator and patient safety, as well as the quality of the sample collected, suggesting the need to review legal and normative issues and to train collaborators. Participants who use systematically these two methodologies are monitoring some of the requirements of ISO 15189:2012, namely 4. 1.2.6, 4.3, 4.4.1, 4.14, 5.4.2 (both), 5.4.4.2 (mystery client) and 5.1.2, 5.2.2, 5.2.5, 5.3.2.5, 5.3.2.7, 5.4.4 (presential audit), contributing to release reliable results for medical decisions. For the future, we will extend the questions and items in evaluation in these two surveys to Microbiology area and continuing to offer training in Preanalytical matters.N/
Asset price distributions and risk aversion : what can we learn from options market?
This dissertation infers descriptive statistical measures from the estimated risk-neutral probability density
functions derived from short-term out-of-the money monthly S&P 500 option prices in respective precrisis
and crisis periods. The generalized beta distribution of the second kind, the mixture of lognormal
distribution and the lognormal polynomial distribution comprise the three parametric methods used to
estimate such density functions. The three estimated risk-neutral probability density functions tend to be
negatively skewed, leptokurtic and exhibit roughly equal distribution mean values.
The constant relative risk aversion coefficient is computed through the method used by Liu et al. (2007)
for quarterly risk-neutral densities. The pre-crisis constant relative risk aversion value is approximately
2.672 with a MLN distribution and 2.666 with a GB2 distribution, compared to constant relative risk
aversion of 2.507 and 2.477, respectively, during the crisis period. The real-world densities became less
skewed, less kurtic and contain a higher first-moment value than the risk-neutral densities. Results are
fairly consistent with available academic literature
Performance of PNAEQ participant’s results for HIV and HCV infection in the First EQA round 2019
The Portuguese National External Quality Assessment Program (PNAEQ) has been collaborating with Labquality since 2002. One of the first schemes distributed to PNAEQ participants was for HIV laboratory tests, followed by HCV laboratory tests scheme in 2003. A suitable scheme for Point of Care Testing (POCT) is available for HIV since 2012 and for HCV since 2018. Given the burden of HIV and HCV diseases, the Portuguese legislation allows, since 2018, that other locations than laboratories, such as pharmacies and Non-Governmental-Organizations (NGOs), perform tests for detect HIV and HCV infection. For this purpose, and in order to assure reliable results that leads to an early correct diagnostic and a timely treatment, leading to a decrease in the person-to-person transmission of HIV and HCV infection, a specific training to perform POCT for HIV and HCV is mandatory for these entities, as well as the participation in such EQA schemes, namely the PNAEQ-Labquality. The performance of PNAEQ participants for HIV and HCV tests in the First EQA round 2019 was considered in general good. For HIV POCT, the user that reported an undetermined result proceeded correctly requesting a second sample for confirmation. Regarding the two incorrect results reported by laboratories, it is necessary to review the internal validation procedure and revalidation of the laboratory test, and implement corrective and preventive actions.
The training of participants that used POCT for the first time proved to be effective in acquiring skills to perform the tests properly. PNAEQ will continue to provide education and training in quality control and motivate all the participants to continuously evaluate the results from the internal quality control and the reports from the external quality assessment.N/
The Role of the Ombudsman in the Defense of Fundamental Rights
En Portugal, al Proveedor de justicia es el equivalente al Ombudsman y se caracteriza por ser un órgano independiente de control de la actividad de la Administración pública.
Fue instituido en la década de 1970 y su objetivo es también la defensa de los derechos fundamentales de los ciudadanos. En el presente artÃculo, la autora subraya esta función defensora de protección y promoción de ios derechos fundamentales, resaltando los derechos más reclamados al Defensor del Pueblo portugués y reflejando las competencias constitucionales y estatutarias de la Institución y su especÃfica adecuación para el reconocimiento del Proveedor de Justicia, como un defensor de los derechos humanos.The Proveedor de Justicia, although corresponding to the classic Ombudsman model as an independent body to control the activities of the public administration, has been
established, in the 1970s, also with a mandate of defence of fundamental rights. In the present article, the author emphasises this Ombudsman's function of protection and promotion of fundamental rights, exposing, on one hand, the rights which are more frequently complained about to the Portuguese Ombudsman and, on the other hand, reflecting on certain constitutional and statutory powers granted to the institution and respective adequacy for the recogmtion ofthe Proveedor de Justicia as an human rights defender
Doença Coronária e Disfunção Erétil
Introdução: A doença coronária é uma das principais causas de morbilidade e mortalidade
em todo mundo. (1) A aterosclerose é uma doença inflamatória crónica multifatorial que
ocorre como resposta à lesão endotelial. Assim sendo, a disfunção erétil apresenta
processos patofisiológicos e fatores de risco semelhantes aos da doença coronária, uma vez
que a lesão endotelial é um denominador comum. (2) Desta forma, fatores de risco
cardiovascular, como a hipertensão arterial, dislipidemia, diabetes mellitus, obesidade e
tabagismo são comuns a estas duas patologias. (3) Assim sendo, vários estudos
demonstram a Ãntima relação entre estas duas condições, evidenciando que uma
proporção significativa (42-89%) dos indivÃduos diagnosticados com doença coronária
apresentam disfunção erétil. (4,5)
Objetivos: Verificar a existência de relação entre a doença coronária e a disfunção erétil.
Bem como avaliar a relevância estatÃstica de variáveis como a idade, fatores de risco
cardiovascular e fármacos anti-hipertensores.
Metodologia: Este estudo foi realizado entre janeiro e março de 2020 na Consulta externa
de Cardiologia do Centro Hospitalar Universitário Cova da Beira. A recolha de dados
baseou-se na aplicação de um questionário que avaliava a função erétil dos doentes
coronários, bem como informações clÃnicas e sociodemográficas.
Resultados: Foram estudados 50 indivÃduos do sexo masculino com idades entre os 48 e
81 anos. Verificou-se que nesta amostra, 62% dos indivÃduos praticavam atividade sexual,
dos quais 71% apresentavam algum grau de disfunção erétil. Demonstrou-se haver uma
relação estatisticamente significativa entre a variável Ãndice de massa corporal e a
presença de disfunção (p-value = 0,007), bem como entre o uso de bloqueadores dos
canais de cálcio e a função erétil (p-value = 0,03). Para além disso, verificou-se que
indivÃduos com Ãndice de massa corporal superior ou igual a 25 apresentavam um risco
relativo de ter DE de 6,8 (intervalo de confiança de 95% entre 1,233 – 37,497). Por outro
lado, no que diz respeito à caracterização da doença coronária não se verificaram
diferenças estatisticamente significativas.
Conclusões: Tendo em conta os resultados obtidos, demonstrou-se que nesta amostra
existe uma elevada prevalência de disfunção erétil, concordante com a literatura. Da
mesma forma, outros estudos comprovaram a relação entre o Ãndice de massa corporal e a
disfunção erétil. Por outro lado, foram obtidos resultados discordantes no que diz respeito aos bloqueadores dos canais de cálcio, sendo por isso necessário um estudo com uma
dimensão superior para avaliar o seu verdadeiro impacto. De facto, uma das principais
causas para que não se verificassem mais relações entre as diferentes variáveis é sem
dúvida a pequena amostra em estudo. Assim, importa destacar que este estudo pretende
em primeira instância alertar para a relação entre estas duas patologias, de forma a que
melhores estratégias preventivas possam ser alcançadas.Introduction: Coronary artery disease is a major cause of morbidity and mortality
worldwide. (1) Atherosclerosis is a multifactorial chronic inflammatory disease that occurs
in response to endothelial injury. Therefore, erectile dysfunction has pathophysiological
mechanisms and risk factors similar to those of coronary disease, since endothelial injury
is a common denominator. (2) Thus, cardiovascular risk factors such as hypertension,
dyslipidemia, diabetes mellitus, obesity and smoking are common to these two
pathologies. (3) Accordingly, several studies demonstrate the close relationship between
these two conditions, showing that a significant proportion (42-89%) of individuals
diagnosed with coronary disease have erectile dysfunction. (4,5)
Objective: To verify the existence of a relationship between coronary artery disease and
erectile dysfunction. As well as assessing the statistical relevance of variables such as age,
cardiovascular risk factors and antihypertensive drugs.
Methodology: This study was carried out between January and March 2020 at the
Cardiology Outpatient Clinic of Cova da Beira University Hospital Center. Data collection
was based on the application of a questionnaire that assessed the erectile function of
coronary patients, as well as clinical and sociodemographic information.
Results: Fifty male individuals aged between 48 and 81 years old were studied. In this
sample it was found that 62% of the participants had regular sexual activity, of which 71%
had some degree of erectile dysfunction. There was a statistically significant relationship
between the variable body mass index and the presence of dysfunction (p-value = 0.007),
as well as between the use of calcium channel blockers and erectile function (p-value =
0,03). In addition, it was found that individuals with a body mass index greater than or
equal to 25 had a relative risk of having erectile dysfunction of 6.8 (95% confidence
interval between 1.233 - 37.497). On the other hand, with regard to the characterization of
coronary disease, there were no statistically significant differences.
Conclusions: Taking into account the results obtained, it was demonstrated that in this
sample there is a high prevalence of erectile dysfunction, in agreement with the literature.
Likewise, other studies have proven the relationship between body mass index and erectile
dysfunction. On the other hand, conflicting results were obtained with regard to calcium
channel blockers, which is why a larger study is needed to assess its true impact. In fact,
one of the main reasons for not having more relationships between the different variables is undoubtedly the small sample under study. Thus, it is important to highlight that this
study intends to alert to the relationship between these two diseases, so that better
preventive strategies can be achieved
Celebridades nas propagandas de medicamentos: um estudo acerca das dimensões da credibilidade do endossante e seus impactos na atitude e intenção de compra do consumidor
TCC (graduação) - Universidade Federal de Santa Catarina, Centro Sócio Econômico, Curso de Administração.A indústria farmacêutica encontra-se no ranking dos setores econômicos que mais investem em publicidade no Brasil. Em 2014 ocupava o décimo lugar com investimento anual de R 6.040.390. Last year, the investments in advertising went over the figure of eight million reais, making the sector to occupy the sixth spot on the ranking. It is well known that one of the most frequently used advertising strategies by this industry, even if really costly, is to hire celebrities to endorse the purchase or the use of a determined medicine. The advertising of medicines directly to the consumer can be a risk inducing practice. The self-medication, inadequate use, inaccurate dosages, intoxication risks, layman’s diagnosis and the belief that some medicine is completely safe, are just some of the problems that appear among the debate on the legitimacy of medicine advertising. As they are potentially dangerous to the health, unlikely more common consumer goods, the medicines can’t be regulated only by the law of supply and demand, once that, if consumed incorrectly can cause serious injuries to health and even death, in the most extreme cases. In Brazil, the advertising directly oriented to the consumer is only allowed if the medicine does not need medical prescription, also known as free sale medicines. Those are the ads that celebrities appear sole, as characters, with their family or children, and many times, being humorous and using figure of speech. Studies about the endorse of celebrities made on common goods, like sneakers, clothes, perfume and cell phones, show that the efficiency of the endorse in the ads are directly connected to the credibility of the endorsing celebrity. However, it was not found any study that tested if that effect is also observed in ads of medicines, once that they are not common consumer goods. Trying to fill this gap, this study inquired if the credibility of the endorser influences the buying intent and attitudes of the consumer regarding the ad and the brand from the viewpoint of the three dimensions of credibility suggested by Ohanian (1990), trustworthiness, attractiveness and expertise. For this end, an experiment was conducted in 12 classes of students enrolled in administration at UFSC. The classes were exposed to ads of medicines with endorse of celebrities with different levels of credibility. From the analyses of the data, it was found that there is a linear positive correlation between the credibility and the attitude towards the brand, the ad and the buying intent, it being stronger in the two last. As for the dimensions, the expertise displayed a strong association with the attitude towards the ad (r=0,7). But, the buying intent and attitude towards the brand were more influenced by the trustworthiness of the endorser. It was observed that the attractiveness was the least impactful dimension between the studied variables
Tradução e validação para a população portuguesa da Individual Workload Perception Scale - Revised
As condições de trabalho dos enfermeiros têm vindo a ser alvo de preocupação e interesse crescentes
por parte dos investigadores e gestores, por serem impulsionadoras da qualidade dos cuidados e dos
nÃveis de satisfação dos profissionais e dos clientes. Neste sentido, o ambiente da prática de enfermagem
é fortemente influenciado pelos comportamentos, produtividade, motivação e satisfação dos
profissionais. Para a existência de um ambiente favorável é necessário que todos estes aspetos se
desenvolvam e prosperem. A área da enfermagem é reconhecida pelos elevados nÃveis de stress
associados ao ambiente de trabalho. Os enfermeiros estão constantemente sujeitos a riscos psicossociais
com impacto a nÃvel fÃsico, psicológico e social, decorrentes de fatores de sobrecarga de trabalho,
interação e conflitos com os pares ou outros profissionais, horários por turnos, carência de recursos
materiais/técnicos/humanos e exigências emocionais inerentes ao contacto direto com os clientes. As
tentativas de descrever esta questão complexa da carga de trabalho em enfermagem têm-se concentrado
em medidas objetivas, tais como: horas por dia de cuidados de enfermagem ao cliente, e nÃveis de
dependência do cliente determinados pela quantidade de cuidados realizados durante um certo perÃodo.
Estes métodos não têm em conta a experiência e as competências dos profissionais de saúde, nem os
problemas com o suporte do enfermeiro gestor/pares e as limitações dos recursos. A escala Individual
Workload Perception Scale – Revised (IWPS-R) foi desenvolvida para ser um instrumento que avalia a
satisfação dos enfermeiros relativamente à sua carga de trabalho. Deste modo, o objetivo do presente
estudo é adaptar culturalmente/ linguisticamente e validar a escala IWPS-R, dando origem à versão
portuguesa da mesma. Para tal, recorreu-se a um estudo do tipo quantitativo, observacional e descritivo transversal, sendo o instrumento validado numa amostra de 323 enfermeiros pertencentes a um centro
hospitalar. A sua aplicação decorreu desde 10 a 26 de fevereiro, sendo a maioria da amostra pertencente
ao sexo feminino (87,3%) e a média de idades a situar-se no intervalo de idades dos 30 aos 39 anos.
Para validação do questionário foi solicitada autorização à autora da escala IWPS-R original, bem como
ao Conselho de Administração e Comissão de Ética da instituição envolvida. A fiabilidade foi garantida
através da determinação da consistência interna, tendo sido testada através do Alfa de Cronbach onde
se obteve 0,9, com exclusão de 8 itens. A validade de conteúdo foi garantida pela realização do teste de
compreensão e a validade de construto através da análise fatorial, cuja análise de componentes principais
deu origem a uma matriz constituÃda por cinco fatores: Suporte do Enfermeiro Gestor, Suporte da
Equipa, Carga de Trabalho, Recursos da Organização, Intenção de Permanecer. A IWPS-R revelou ser
um instrumento adequado para ser aplicado no contexto cultural português, através das suas
caracterÃsticas psicométricas.Nurses´ working conditions have been the subject of growing concern and interest for researchers and
managers, as these conditions drive the quality of care and the levels of satisfaction of professionals and
clients. In this sense, the nursing practice environment is strongly influenced by the behaviors,
productivity, motivation and satisfaction of professionals. For a favorable environment, all these aspects
must develop and prosper. The nursing job is recognized for the high levels of stress associated with the
work environment. There are psychosocial risks inherent to the nursing practice, with a physical,
psychological and social impact on the professionals, due to work overload factors, conflicts with peers
or other professionals, shift schedules, lack of material/technical/human resources, and emotional
demands associated to the direct contact with customers. Attempts to describe the complex issue of
nursing workload have focused on objective measures, such as: hours per day of nursing client care, and
client dependency levels determined by the amount of care performed over a given period. However,
these methods don´t consider relevant aspects, like the experience and skills of the professionals, limited
support from nurse manager/peers, and resource limitations. The Individual Workload Perception Scale
– Revised (IWPS-R) was developed to be an instrument that assesses nurses' satisfaction with their
workload. Thus, the objective of the present study is to culturally/linguistically adapt and validate the
IWPS-R scale, so it can be developed the Portuguese version of it. In order to achieve this, the instrument
was validated in a sample of 323 nurses from a hospital center, through a quantitative, observational and
descriptive/cross-sectional study. Its application took place from the 10th to the 26th of February, with
the majority of the sample belonging to the female sex (87.3%) and the average age between 30 to 39
years. For validation of the questionnaire, it was requested authorization from the original IWPS-R
scale´s author, as well as from the Directors´ Board and the Ethics Committee of the institution involved.
Reliability was guaranteed by the determination of internal consistency, through the measure of
Cronbach's Alpha, where 0.9 was obtained and 8 items were excluded. Content validity was guaranteed
by carrying out the comprehension test. Construct validity, in turn, it was assured through factor
analysis, whose main components analysis gave rise to a five factors matrix: Support from the Nurse
Manager, Team Support, Workload, Organization Resources, and Intent to Stay. It was proved that the
IWPS-R is a suitable instrument for application in the Portuguese cultural context, through its
psychometric characteristics
