Feasibility of cardiovascular risk screening in Portuguese community pharmacies.

BACKGROUND: Cardiovascular disease (CVD) remains the leading cause of human mortality. As highly accessible and qualified health professionals, community pharmacists can be included in the early detection of patients at risk for CVD by implementing CVD screening programs. OBJECTIVE: To assess the feasibility of CVD risk screening services in Portuguese community pharmacies from the evaluation of customers acceptability. METHODS: A cross-sectional study was conducted in a community pharmacy in Portugal. The purpose of entering the pharmacy was recorded for all customers. Afterwards, the customers were invited to be interviewed by the pharmacist, who registered their willingness to participate and collected the participants' data and biochemical and physical parameters to assess their CV risk by applying the Systematic COronary Risk Evaluation (SCORE) model. For the participants who were not eligible for the SCORE-based risk assessment, the pharmacist considered the major modifiable CVD risk factors - hypertension, dyslipidemia, smoking habits, obesity, impaired fasting glucose and sedentary behavior - according to the ESC guidelines. RESULTS: Picking up medication was the most prevalent reason 69.8% (n=1,600) for entering the pharmacy, and among the contacted customers, 56.4% (n=621) agreed to have their CVD risk assessed. Of the 588 participants, 56.6% (n=333) were already on CV pharmacotherapy and were therefore not eligible for screening. Of the 43.4% (n=255) CV pharmacotherapy-naïve participants, 94.9% (n=242) were screened with at least one CVD risk factor; 52.9% (n=135) were not eligible for the SCORE assessment, of which 92.6% (n=125) presented CVD risk factors. Of the 120 SCORE eligible participants, 80.0% (n=96) were at least at moderate risk of CVD. CONCLUSIONS: We determined the feasibility of CVD risk screening in Portuguese community pharmacies, as we found high customer acceptability, noted the reasons for nonattendance, and found a high prevalence of CVD risk factors in at-risk patients. This is an opportunity for Portuguese community pharmacists to take a leading role in the early detection of CVD.

Proof-of-Concept Study of Multifunctional Hybrid Nanoparticle System Combined with NIR Laser Irradiation for the Treatment of Melanoma.

The global impact of cancer emphasizes the importance of developing innovative, effective and minimally invasive therapies. In the context of superficial cancers, the development of a multifunctional nanoparticle-based system and its in vitro and in vivo safety and efficacy characterization are, herein, proposed as a proof-of-concept. This multifunctional system consists of gold nanoparticles coated with hyaluronic and oleic acids, and functionalized with epidermal growth factor for greater specificity towards cutaneous melanoma cells. This nanoparticle system is activated by a near-infrared laser. The characterization of this nanoparticle system included several phases, with in vitro assays being firstly performed to assess the safety of gold nanoparticles without laser irradiation. Then, hairless immunocompromised mice were selected for a xenograft model upon inoculation of A375 human melanoma cells. Treatment with near-infrared laser irradiation for five minutes combined with in situ administration of the nanoparticles showed a tumor volume reduction of approximately 80% and, in some cases, led to the formation of several necrotic foci, observed histologically. No significant skin erythema at the irradiation zone was verified, nor other harmful effects on the excised organs. In conclusion, these assays suggest that this system is safe and shows promising results for the treatment of superficial melanoma.

A Step Forward in Breast Cancer Research: From a Natural-Like Experimental Model to a Preliminary Photothermal Approach.

Breast cancer is one of the most frequently diagnosed malignancies and common causes of cancer death in women. Recent studies suggest that environmental exposures to certain chemicals, such as 7,12-Dimethylbenzanthracene (DMBA), a chemical present in tobacco, may increase the risk of developing breast cancer later in life. The first-line treatments for breast cancer (surgery, chemotherapy or a combination of both) are generally invasive and frequently associated with severe side effects and high comorbidity. Consequently, novel approaches are strongly required to find more natural-like experimental models that better reflect the tumors' etiology, physiopathology and response to treatments, as well as to find more targeted, efficient and minimally invasive treatments. This study proposes the development and an in deep biological characterization of an experimental model using DMBA-tumor-induction in Sprague-Dawley female rats. Moreover, a photothermal therapy approach using a near-infrared laser coupled with gold nanoparticles was preliminarily assessed. The gold nanoparticles were functionalized with Epidermal Growth Factor, and their physicochemical properties and in vitro effects were characterized. DMBA proved to be a very good and selective inductor of breast cancer, with 100% incidence and inducing an average of 4.7 tumors per animal. Epigenetic analysis showed that tumors classified with worst prognosis were hypomethylated. The tumor-induced rats were then subjected to a preliminary treatment using functionalized gold nanoparticles and its activation by laser (650-900 nm). The treatment outcomes presented very promising alterations in terms of tumor histology, confirming the presence of necrosis in most of the cases. Although this study revealed encouraging results as a breast cancer therapy, it is important to define tumor eligibility and specific efficiency criteria to further assess its application in breast cancer treatment on other species.

Consequences of ignoring patient diagnoses when using the 2015 Updated Beers Criteria.

BACKGROUND: Beers Criteria are one of the best known explicit criteria to identify inappropriate medication in elderly that can be used in medication review. The access to patients' medical records may be different among healthcare professionals and settings and, subsequently, the identification of patients' diagnoses may be compromised. OBJECTIVE: To assess the consequences of ignoring patient diagnoses when applying 2015 Beers Criteria to identify potentially inappropriate medication (PIM). SETTING: Three nursing homes in Central Portugal. METHOD: Medical records of nursing home residents over 65 years old were appraised to identify medication profile and medical conditions. 2015 Beers Criteria were used with and without considering patients' diagnoses. To compare the number of PIM and PIM-qualifying criteria complied in these two judgements, Wilcoxon signed-rank tests were performed. MAIN OUTCOME MEASURE: Number of PIMs and number of PIM-qualifying criteria. RESULTS: A total of 185 patients with a mean age of 86.7 years (SD = 7.8) with a majority of female (70.3%) were studied. When assessing the patients with full access to the diagnoses, median number of PIMs was 4 (IQR 0-10) and number of PIM-qualifying criteria was 5 (IQR 0-15). When evaluating only patient current medication, median number of PIMs was 4 (IQR 0-10) and PIM-qualifying criteria was 4 (IQR 0-12). Statistical difference was found in the number of PIM-qualifying criteria identified (p < 0.001), but not in the number of PIMs per patient (p = 0.090). In 171 patients (92.4%) PIMs identified were identical when using or ignoring their medical diagnoses. However, in 80 patients (43.2%) the PIM-qualifying criteria complied were different with and without access to patient diagnoses. CONCLUSION: Although restricted access to patients' diagnoses may limit the judgement of Beers PIM-qualifying criteria, this limitation had no effect on the number of PIM identified.

Cross-cultural adaptation of Hypertension Knowledge Test into European Portuguese

ABSTRACT We aim to validate a European-Portuguese version of the Hypertension Knowledge Test (HKT) questionnaire and examine its factorial structure with a confirmatory factor analysis (CFA). A process of translation and back-translation was performed. A cross-sectional study was developed in which all adult patients taking at least one antihypertensive drug were invited to participate. Data on personal and family history were collected, and the HKT, Strelec, and the Batalla questionnaires were administered. We enrolled 304 patients with a mean age of 68.12±10.83 years. The mean score of HKT was 15.33±2.79. CFA indicated that the construct being tested was unidimensional, and Cronbach's alpha (α=0.65) showed that the instrument had an acceptable internal consistency. When evaluating concurrent validity, HKT was significantly correlated with the Batalla and Strelec scores. Thus, the Portuguese version of HKT (HKT-pt-PT) can be used either in research or in clinical practice. With this version, a potential standard exists to evaluate knowledge about hypertension, which could avoid the practice of using non-validated questionnaires in Portugal and allow the cross-sectional and longitudinal comparability of studies.

Smoking cessation in a community pharmacy: preliminary results of a pharmaceutical care programme / Cesación tabáquica en farmacia comunitaria: resultados preliminares de un programa de atención farmacéutica

Background: According to the World Health Organisation, tobacco use is one of the most widespread public health threats in the world, making it particularly urgent to promote smoking cessation. The effectiveness of pharmacist interventions in smoking cessation has been documented in the international literature, but not sufficiently in Portugal. Objective: To report the preliminary results of study to assess the effectiveness of a smoking cessation programme delivered in Portuguese community pharmacies using an outsorcing-based regimen. Methods: Within the scope of a pharmaceutical care programme implemented in seven community pharmacies by an outsourced pharmacist, a specific consultation for smoking cessation was developed, in accordance with Portugal's General Directorate of Health's recommendations and instruments. The smokers were identified and invited to join the programme by the pharmacy staff during their daily activities. Patients that accepted signed an informed consent. Through several face-to-face and phone consultations and based on a comprehensive patient approach, personalised plans to quit tobacco were defined with the patients' agreement. The effectiveness of the service was assessed through the evaluation of quit rates at 1, 6 and 12 months. The continuous variables were expressed as mean ± standard error of the mean. Results: During approximately 5 years (between January 2009 and July 2014), 69 smokers joined the programme. Of these, 17 desisted during the first consultation. Of the remaining 52 patients, the mean age was 47.4 ± 2.11 years old and 55.8% were male. A total of 264 pharmaceutical consultations were delivered and, on average, each patient received 7.7 ± 0.81 interventions. Most interventions (60.1%) were pharmacological (e.g. nicotine replacement products), while non-pharmacological measures (e.g. motivational interviewing) represented 39.9%. Five patients were referred to a physician. At 1 month after the quit date, 37 patients were abstinent (53.6%); 6 months later the number reduced to 24 (34.8%) and, 1 year later, 16 patients remained abstinent (23.2%). Conclusions: The implementation of a smoking cessation programme in community pharmacies using an external pharmacist may contribute effectively to tobacco cessation in Portugal.

Antecedentes: Según la Organización Mundial de la Salud, el tabaco es una de las mayores amenazas del mundo, siendo urgente promover el abandono tabáquico. La efectividad de las intervenciones farmacéuticas en cesación tabáquica ha sido documentada en la literatura, pero no en Portugal. Objetivo: Comunicar los resultados preliminares de un estudio para evaluar la efectividad de un programa de cesación tabáquica desarrollado en farmacias comunitarias portuguesas usando un régimen de out-sourcing. Métodos: En el ámbito de un programa de atención farmacéutica implantado en siete farmacias por un farmacéutico externalizado, se desarrolló una consulta de cesación tabáquica siguiendo las recomendaciones e instrumentos de la Dirección General de Salud de Portugal. Se identificó a los fumadores y el personal de la farmacia durante sus actividades rutinarias les invitó a unirse al programa. Los que aceptaban firmaban un consentimiento informado. Mediante consultas presenciales y telefónicas y a través de un abordaje global del paciente, se definieron en acuerdo con el paciente planes personalizados de abandono del tabaquismo. La efectividad del servicio se midió mediante las tasas de cesación a 1, 6 y 12 meses. Las variables continuas se expresaron como media ± error estándar de la media. Resultados: Durante aproximadamente 5 años (entre enero 2009 y julio 2014), 69 fumadores se unieron al programa. De estos, 17 desistieron durante la primera consulta. Entre los restantes 52 pacientes, tenían 47.4 ± 2.11 años y el 55,8% eran hombres. Se realizaron 264 consultas farmacéuticas y, en media cada paciente recibió 7.7 ± 0.81 intervenciones. La mayoría de las intervenciones (60,1%) eran farmacológicas (p.e. productos de substitución de nicotina), y el restante 39,9% fueron medidas no farmacológicas (p.e. entrevista motivacional). Cinco pacientes fueron remitidos al médico. Después de 1 mes de la fecha convenida para el inicio de la cesación, 37 pacientes (53,6%) estaban en abstinencia; 6 meses más tarde el número se reducía a 24 (34,8%) y un año más tarde 16 pacientes (23,2%) permanecían abstinentes. Conclusión: La implantación de un programa de casación tabáquica en farmacias comunitarias, utilizando un farmacéutico externo, puede contribuir efectivamente a la cesación tabáquica en Portugal.

[Development of a multidimensional system for classification and management of health information: applying to clinical information]. / Desenvolvimento de um sistema multidimensional para classificação e gestão de informação em saúde: aplicabilidade à informação clínica.

INTRODUCTION: The large amount of information in the medical area creates management problems, being necessary systematic methods for filing and retrieval. With information on the context of clinical records, methods must integrate controlled biomedical terminologies and desirable characteristics oriented to the structure, content and clinical results. The objective is to test the applicability and capacity for retrieval of a multidimensional system developed for classification and management of health information. METHODS: Three hundred questions were randomly selected, by computerized method, from the questions received in six years (Medicine Information Service, Pharmaceutical Department, Coimbra University Hospitals). They were characterized and applicability evaluated by classified amount and need to alter the system, which is composed of various independent dimensions, incorporating concepts sometimes hierarchical. Questions retrieval was tested searching information in a dimension or between dimensions. RESULTS: All questions were classified: 53% are clinical cases with illnesses incidence in the genitourinary system; metabolic, nutritional and endocrine disease; cancer; infections and nervous system. In 81%, the object is a drug, mostly anti-infectious and anti-neoplastic agents. The therapeutic and safety areas had been the most requested, regarding the subjects: use, adverse reactions, drug identification and pharmaceutical technology. As to applicability, it was necessary to add some concepts and modify same hierarchical groups, that didn't modify the basic structure, nor had collided with the desirable characteristics. The limitations were related with the incorporated external classification systems. The search in the subject dimension of the concept drug administration retrieved 19 questions. The search between two dimensions: antiinfectious (external) and teratogenicity (subject) retrieved three questions. In the two examples, it was possible to retrieve information from any one of the levels of the hierarchy, from the most general to the most specific and even from external dimensions. CONCLUSIONS: The use of the system in this sample showed its applicability in clinical information classification and filing, retrieval capacity and flexibility, supporting modifications without interfering with desirable characteristics. This tool allows retrieval of patient-oriented evidence that matters.
