Pharmaceutical care improves medication adherence and quality of life in type 2 diabetes mellitus

Aims: This study aimed to evaluate whether pharmacotherapeutic follow-up in patients with T2DM in primary care interferes in metabolic control, cardiovascular risk, medication adherence and quality of life. Methods: A prospective clinical study was conducted at two Primary Health Units in Vitória, Espírito Santo, Brazil with 75 patients with T2DM between 40 and 70 years old. The parameters of metabolic control evaluated included fasting blood glucose, HbA1c, triglyceride/HDL-c and total cholesterol/HDL-c ratio. The cardiovascular risk was calculated based on the Framingham risk score. Adherence to medication was measured using the Brief Medication Questionnaire and quality of life was evaluated by applying the World Health Organization Quality of Life-Bref. Results: After the follow-up, there was a significant decreasing in cardiovascular risk (p=0.048) and total cholesterol/HDL-c ratio (p=0.024) and a discrete improvement in fast glucose and HbA1c levels. The quality of life scores increased for all domains (p<0.0001) and the treatment adherence also improved with 12.00% of the patients classified as low adherence in the final time, against 41.33% before the meetings. Conclusion: These results show the proposed pharmacotherapeutic follow-up influenced positively cardiovascular risk, adherence to therapy and quality of life in all domains, and, therefore, may contribute to delay the onset of the main chronic complications of the disease (AU)

Pesticide exposure and poisoning in Brazil: Outcome severity, clinical manifestations and management of cases reported to a poison control center.

This work aimed to identify variables associated with increased risk of outcome severity as well as to describe clinical manifestations/symptoms and management of pesticide-related cases reported to a poison center in Brazil. An increased risk of more severe outcomes was observed when exposures occurred in rural areas, involved suicide attempts and moderately to extremely hazardous pesticides. Clinical manifestations with higher frequencies included vomiting, nausea, sialorrhea, headache, miosis and sweating. From the treatment initially applied to the patient, 51.91% encompassed gastric lavage, but this procedure was only recommended in 20.01% of cases by the CIATox. Identifying risk factors associated with poor outcome, describing clinical manifestations, and contrasting initial treatment measures adopted against those recommended by the Poison Center can help determine diagnosis, prognosis and ensure appropriate clinical interventions are used in cases of pesticide poisoning.

High-risk pregnancy: characterization of medication use profile and association with clinical and sociodemographic factors / Gestação de alto risco: caracterização do perfil de utilização de medicamentos e associação com fatores clínicos e sociodemográficos

Abstract Objectives: describe the profile of medication use and adherence, and the association with clinical and sociodemographic characteristics of high-risk pregnant women attended at a university hospital. Methods: cross-sectional study with data collected through a questionnaire applied on 386 pregnant women. Results: most participants were seen only by the gynecologist (75.1%), started prenatal in the first gestational trimester (86.8%), did not plan the pregnancy (61.9%), and performed an average of 8.2 (SD=4.4) prenatal consultations. The most frequent diagnoses were arterial hypertension (20.5%) and diabetes mellitus (19.7%). Prevalence of medication use was 99.7%, with an average of 5.1 (SD=2.1) medication per woman and 12.7% self-medication. Antianemics (88.9%) and analgesics (63.2%) were the most prevalent classes and 17.9% of the women reported the use of medication with significant gestational risk. Only 36.5% were considered adherent, 32.9% declared they were unaware of the indication of the medication in use and 42% did not receive guidance on the use of the medication during pregnancy. There is no evidence of association between the number of the medication used and clinical and sociodemographic aspects. Conclusions: there is a need to develop strategies to improve the care of this population, with emphasis on strengthening multi-professional care.

Métodos: trata-se de um estudo transversal com dados coletados mediante um questionário estruturado aplicado à 386 gestantes. Resultados: a maior parte das participantes era acompanhada apenas pelo ginecologista (75,1%), iniciou o pré-natal no primeiro trimestre gestacional (86,8%), não planejou a gravidez (61,9%) e realizou em média 8,2 (DP=4,4) consultas de pré-natal. Os diagnósticos mais frequentes foram hipertensão arterial (20,5%) e diabetes mellitus (19,7%). A prevalência de uso de medicamentos foi 99,7%, com média de 5,1 (DP=2,1) medicamentos por mulher e 12,7% de automedicação. Os antianêmicos (88,9%) e analgésicos (63,2%) foram as classes farmacológicas mais prevalentes e 17,9% das gestantes referiram uso de fármacos com risco gestacional relevante. Apenas 36,5% das gestantes foram consideradas aderentes ao tratamento, 32,9% declararam desconhecer a indicação dos medicamentos em uso e 42% não receberam orientações sobre o uso de medicamentos durante a gestação. Não há evidências de associação entre o número de medicamentos utilizados e os aspectos clínicos e sociodemográficos. Conclusão: é necessário desenvolver estratégias para melhorar o atendimento desta população e o uso racional de medicamentos, com ênfase no fortalecimento do cuidado multiprofssional.

Health-Related Quality of Life and Coping Strategies in a Cohort Study of Highly Active Antiretroviral Therapy Naïve Patients Adherence.

Objective: The main objective of this study was to describe the perceived quality of life (QoL) in patients living with AIDS (PLWA) and their chosen coping strategies in a cohort of individuals managed with HAART. Methods: This is a prospective cohort study conducted at the Medication Dispensing Unit of a university hospital (MDU-UH) located in southeastern Brazil. Study population comprised HIV/AIDS patients starting antiretroviral treatment at MDU. The final sample comprised 99 participants. Patients were followed up for 24 months from their recruitment. We used a face-to-face questionnaire to determine sociodemographic and behavioural variables. Quality of life (QoL) and coping strategies (CS) were measured through validated instruments. Results: Regarding the QoL dimensions, the general perception of QoL among these participants was considered good. Regarding CS, the adherent patients scored higher than the nonadherents. Conclusions: The present study revealed that the perceived QoL can be maintained in individuals treated for HIV/AIDS. There is an association between high score of coping strategies and adherence to HAART.

Implementation of Medication Reconciliation conducted by hospital pharmacists: A case study guided by the Consolidated Framework for Implementation Research.

BACKGROUND: Medication reconciliation (MR) implementation in hospital care transitions has proved to be a challenge for health professionals and managers. It points to the need to conduct Implementation Research with a view to understanding the tasks of the real world and knowing how they impact this process. Guided by the Consolidated Framework for Implementation Research (CFIR), this study aims to analyze the factors that influenced the MR implementation process conducted by pharmacists at a hospital setting. METHODS: A qualitative case study was carried out in the cardiology and gastroenterology units of a teaching hospital in Brazil, involving participant observation and semi-structured interviews with physicians, pharmacists, nurses, nutritionists and a social worker. The CFIR was used to guide data collection and thematic analysis. The constructs were classified according to their influence and strength. RESULTS: Sixteen health professionals involved directly or indirectly with MR implementation participated in the study. Based on the analysis of the participants' quotes and of the field diary, 18 constructs of the CFIR were identified as influencing MR implementation. The constructs that most strongly influenced MR implementation concerned "Inner Setting", "Characteristics of Individuals" and "Characteristics of Intervention". The participating professionals showed little knowledge of MR and had different points of view on its scope, weakly relating MR to patient safety. The tools used to conduct MR were adapted according to the hospital's needs, thus facilitating its implementation. However, MR proved to be complex and require clinical knowledge and aligned teamwork to identify and resolve undocumented medication discrepancies, being as well intertwined with culture and organizational communication. CONCLUSIONS: The results point to implementation failures and highlight that MR is a complex intervention, requiring specific knowledge from the multidisciplinary team and alignment with other existing workflows. The barriers and facilitators identified may serve to design and test implementation improvement strategies.

Functional evaluation of immunoregulatory molecules HLA-G, galectin-1, and IL-10 in people living with HIV.

OBJECTIVES: Investigate polymorphisms and expressions of human leukocyte antigen-G (HLA-G), galectin-1 (Gal-1), and interleukin-10 (IL-10) in people living with HIV (PLHIV) with and without comorbidities to help understanding the mechanisms involved in triggering these disorders in PLHIV and in their prognosis. DESIGN: Here we evaluated the potential correlation between the genetic polymorphism and/or protein levels of HLA-G, Gal-1, and IL-10 with and without comorbidities of PLHIV. METHODS: Two hundred HIV patients under antiretroviral treatment (83 with comorbidities and 117 without comorbidities) and 200 healthy individuals (controls) were genotyped, using PCR, for HLA-G 14-base pair polymorphism located at the 3' untranslated region in exon 8 insertion/insertion (Ins/Ins: low HLA-G expression) or deletion/deletion (Del/Del: high HLA-G expression). Soluble levels of HLA-G (sHLA-G), Gal-1, and IL-10 were quantified by enzyme-linked immunosorbet assay. RESULTS: HIV patients without comorbidities exhibited higher frequency of 14-base pair Del/Del genotype than HIV patients with comorbidities. As expected, HIV patients Ins/Ins with and without comorbidities produced less sHLA-G than controls. However, HIV patients Del/Del with comorbidities expressed sHLA-G more than controls and HIV patients Del/Del without comorbidities. Interestingly, patients that showed low levels sHLA-G, and presence of comorbidities, exhibited high Gal-1 serum levels. However, an increase in soluble levels of IL-10 in PLHIV was observed when compared to controls, especially in the PLHIV group without comorbidities suggesting, a protective role of IL-10 in the development of comorbidities. CONCLUSIONS: These data suggested that the high expression of sHLA-G and IL-10 or Gal-1 could be associated and could be associated with the development or not of comorbidities in PLHIV.

Perception of pharmacists regarding human resources, training, and development of a national hospital pharmacy: a preliminary report on Basel Statements

Abstract The hospital pharmacy needs a constant process of evaluation and monitoring of its activities. In Brazil, several agencies establish tasks and duties for pharmacists, but little is known about the compliance and the perception of the professional regarding these policies. The present study aims to characterize the pharmacist's perception of Brazilian hospital pharmacy policies according to the Basel Statements. A search was performed for the contacts of all medium and high complexity hospitals in the country. Subsequently, a questionnaire elaborated following the Basel Statements was sent by e-mail to hospital pharmacists throughout the country. The domain analyzed was "Human Resources, Training, and Development". Statistical analyses were performed using SPSS 19.0. Pharmacists representing a total of 111 hospitals from all Brazilian regions answered the survey questionnaire and showed that more than half of the hospital pharmacists perceive themselves as not complying, whether in the service of local, national, or pharmaceutical education. Besides updating the professionals in relation to national policies, it is necessary that the representative bodies of the pharmaceutical class be more present in the elaboration and evaluation of the policies directed to human resources, seeking uniformity and the possibility of carrying out the activities required.

Sociodemographic characteristics and exposure patterns of pesticide-related cases reported to a poison service center in Brazil between 2012 and 2016.

Pesticide poisoning is a significant public health problem responsible for an estimated three million poisoning cases per year and more than 250,000 deaths, most of which occur in underdeveloped countries. We evaluated pesticide exposure cases reported to a toxicological service center in Brazil, between 2012 and 2016. There were 3211 cases of pesticide exposure, with a high prevalence in adults aged 20-39 years (41.2%). Attempted suicide was the leading cause of pesticide cases (48%). Occupational exposure to pesticides of agricultural use was more frequently observed among men. Accidental exposure and attempted suicide were more frequently observed in urban areas while occupational exposure was more prevalent in rural areas. A higher exposure rate was observed among men in counties with higher agricultural activities. Establishing prevalence and cause of pesticide exposure is important to provide subsidy for evidence-based interventions in the field.

Obesity prevalence in Brazilian firefighters and the association of central obesity with personal, occupational and cardiovascular risk factors: a cross-sectional study.

OBJECTIVES: This study aimed to investigate the obesity prevalence in a population of Brazilian firefighters and the association of central obesity (CO) with sociodemographic, occupational, life habits, fitness and health status variables. DESIGN: Cross-sectional study. SETTINGS: The data were collected during annual health inspections of firefighters from the Military Fire Service of the State of Espírito Santo, a state in Southeast Brazil. PARTICIPANTS: The study encompassed 1018 active military firefighters. After exclusion criteria, 892 male firefighters were analysed. PRIMARY AND SECONDARY OUTCOME MEASURES: The collected data included: sociodemographic, occupational, lifestyle, fitness and health status variables. The associations between these factors and CO were calculated by adjusted OR through a hierarchical logistic regression model. RESULTS: Obesity estimation by body mass index indicated that 48.65% of the firefighters were overweight and 10.99% were obese. Concerning the body fat percentage, 26.23% of the participants were considered obese, while 18.61% of the firefighters were considered centrally obese or at risk using the waist circumference measure. After adjusted OR analysis, CO was more likely associated with the age range of 50 to 59 years old (OR 2.93; 95% CI 1.05 to 8.14), low self-reported physical activity (OR 1.95; 95% CI 1.14 to 3.34), low cardiorespiratory fitness (OR 5.15; 95% CI 3.22 to 8.23), hyperglycaemia (OR 1.70; 95% CI 1.07 to 2.72) and hypertriglyceridaemia fasting status (OR 3.12; 95% CI 1.75 to 5.55). CONCLUSIONS: Our study identified an overall high prevalence of overweight and obese individuals in the examined firefighter population. Age and cardiovascular risk factors were directly associated with CO among the firefighters. Cardiovascular risk factors should be routinely inspected within the Brazilian firefighters' corporations in order to improve the health condition and wellness of these workers. These endeavours will improve the performance of the services provided to the population.

Pharmacist-led medication reconciliation at patient discharge: A scoping review.

BACKGROUND: One of the strategies to promote patient safety in care transitions is medication reconciliation (MR), which is conducted by the pharmacist at the patient's discharge from hospital. However, there are divergences about this process and about the pharmacist's role in conducting such intervention. OBJECTIVE: To systematically review the literature that reports the MR process led by pharmacists at patient discharge and map the different methods, strategies and tools used in the process. METHODS: Relevant studies were searched in the following databases: EMBASE, MEDLINE (PubMed), The Cochrane Library, and LILACS. No language restriction or publication date was applied. The studies considered eligible were those involving and describing pharmacist-led MR processes at acute patient discharge from hospital, with an experimental, quasi-experimental, or observational design. The characteristics of the studies and the MR processes were identified and then a qualitative synthesis was performed. RESULTS: Fifty studies were included. The majority of them were observational ones (82%), and the main outcome was medication discrepancies (42%). The studies were mostly conducted in university hospitals (70%) and in internal medicine wards (54%). Pharmacists were responsible mainly for gathering medication histories (72%), and identifying (96%) and solving (98%) pharmacotherapeutic problems. The main sources of information on pre-admission medications were patient/caregiver interviews (66%) and records from other care providers (40%). Only 30% of the studies described a patient discharge plan, and 14% shared information of the patient's pharmacotherapy with community pharmacists. CONCLUSION: The concept of MR and the pharmacist-led activities in the process varied in the literature, as well as the pharmacotherapy assessment focus and the communication strategies towards patients and other care providers, showing that standardization of the process and concepts is necessary.

Comparative efficacy of antiepileptic drugs for patients with generalized epileptic seizures: systematic review and network meta-analyses.

Background Valproate is a widely prescribed antiepileptic drug for generalized epilepsies, due to the extensive knowledge on its efficacy since it is on the market for many decades. However, a large number of new antiepileptic medicines was introduced into clinical practice and may be better options for treatment, considering that these medicines differ in terms of efficacy spectrum. Despite extensive research, questions regarding which medicine would constitute the first option for the monotherapy treatment of generalized epilepsy remain. Aim of the Review To compare the relative efficacy of all available antiepileptic drugs in the monotherapy treatment of generalized epileptic seizures; and also to compare all antiepoileptig drugs with valproate, which is the current first-line treatment for generalized epilepsy. Methods A systematic review for randomized controlled clinical trials was performed. Network meta-analyses used Bayesian random effects model. Sensitivity analyses determined the results´ robustness. The relative probability of two efficacy outcomes ("Seizure free" and "Therapeutic inefficacy") to happen for each medcicine was calculated using the Surface Under the Cumulative Ranking Curve. Results Seven papers (1809 patients) studied the efficacy of valproate, lamotrigine, phenytoin, carbamazepine, topiramate, levetiracetam, and phenobarbital in the treatment of generalized tonicclonic, tonic, and clonic seizures. Phenytoin demonstrated to be inferior to valproate in leaving the patient free of these seizures types [OR: 0.50 (95% CrI 0.27, 0.87)]. Lamotrigine (61%) showed the highest probability of presenting the outcome "Seizure free", followed by levetiracetam (47%), topiramate (44%), and valproate (38%) in the treatment of generalized tonic-clonic, tonic, and clonic seizures. Meanwhile, valproate exhibited greater chance of presenting the outcome "Therapeutic inefficacy" (62%). Regarding absence seizures itself, there was no difference in the efficacy of lamotrigine and ethosuximide when compared to valproate. However, the ranking indicates that ethosuximide (52%) and valproate (47%) are both more likely than lamotrigine to keep the patient free of seizures. Conclusions Lamotrigine, levetiracetam, and topiramate are as effective as valproate for treating generalized tonic-clonic, tonic, and clonic seizures. Meanwhile, valproate and ethosuximide are the best options for the treatment of absence seizures promoting better control of seizures, which is the primary goal of pharmacotherapy.

Hospital pharmacy workforce in Brazil.

BACKGROUND: This study aims to describe the distribution of the hospital pharmacy workforce in Brazil. METHODS: Data were acquired, during 2016, through the Brazilian National Database of Healthcare Facilities (CNES). The following variables were extracted: hospital name, registry number, telephone, e-mail, state, type of institution, subtype, management nature, ownership, presence of research/teaching activities, complexity level, number of hospital beds, presence of pharmacists, number of pharmacists, pharmacist specialization. All statistical analyses were performed by IBM SPSS v.19. RESULTS: The number of hospitals with a complete registry in the national database was 4790. The majority were general hospitals (77.9%), managed by municipalities (66.1%), under public administration (44.0%), had no research/teaching activities (90.5%), classified as medium complexity (71.6%), and had no pharmacist in their team (50.6%). Furthermore, almost 60.0% of hospitals did not comply with the minimum recommendations of having a pharmacist per 50 hospital beds. The Southeast region had the highest prevalence of pharmacists, with 64.4% of hospitals having a pharmaceutical professional. This may have occurred as this region had the highest population to hospital ratio. Non-profit hospitals were more likely to have pharmacists compared to those under public administration and private hospitals. CONCLUSION: This study mapped the hospital pharmacy workforce in Brazil, showing a higher prevalence of hospital pharmacists in the Southeast region, and in non-profit specialized hospitals.

Pharmacists in dispensing drugs (PharmDisp): protocol for a clinical trial to test the effectiveness of distance education in training pharmacists for dispensing drugs

ABSTRACT Dispensing drug is a moment in which the pharmacist is able to analyze pharmacotherapy and contribute to its rational use. However, research has shown that some pharmacists lack adequate knowledge to perform this service. This study aims to describe a research protocol for a clinical trial to test the effectiveness of a distance learning program to train pharmacists in dispensing drugs. This is a protocol for an open diagnostic, non-randomized, single group clinical trial. A 12-week duration distance learning course was structured on the Moodle platform for training community pharmacists who are registered in the Regional Board of Pharmacy and work as employees or owners in Brazilian community pharmacies. The course curricula involves concepts and practice of dispensing drugs applied to the treatment of hypertension, diabetes mellitus, dyslipidemia and asthma. Pharmacists are divided randomly into groups, to which previously selected tutors give directions to the discussion and clarify questions. A validated questionnaire is being used before and after the course to measure participants' knowledge. Participant satisfaction with the course is also being measured. Pharmacists who work in the study headquarters municipality receive two visits from a mystery shopper, before and after the course, to evaluate their performance in dispensing drugs. The virtual platform and the content of the course material were evaluated by judges. The study has been approved by the Research Ethics Committee of the School of Pharmaceutical Sciences of Ribeirão Preto, University of São Paulo. The sample size was estimated to provide desired power for testing the significance of the difference between baseline-to-endpoint change scores. Information about the course is being released through channels such as social networks. The results will be submitted for publication in scientific journals, but information enabling the identification of the study subjects will be kept confidential. The trial has been registered in The Brazilian Clinical Trials Registry with number RBR7mbrp3 on January 15th, 2015.

Cost-effectiveness of insulin analogs from the perspective of the Brazilian public health system

ABSTRACT Human insulin is provided by the Brazilian Public Health System (BPHS) for the treatment of diabetes, however, legal proceedings to acquire insulin analogs have burdened the BPHS health system. The aim of this study was to perform a cost-effectiveness analysis to compare insulin analogs and human insulins. This is a pharmacoeconomic study of cost-effectiveness. The direct medical cost related to insulin extracted from the Ministry of Health drug price list was considered. The clinical results, i.e. reduction in glycated hemoglobin (HbA1c), were extracted by meta-analysis. Different scenarios were structured to measure the uncertainties regarding the costs and reduction in HbA1c. Decision tree was developed for sensitivity of Incremental Cost Effectiveness Ratio (ICER). A total of fifteen scenarios were structured. Given the best-case scenario for the insulin analogs, the insulins aspart, lispro, glargine and detemir showed an ICER of R$ 1,768.59; R$ 3,308.54; R$ 11,718.75 and R$ 2,685.22, respectively. In all scenarios in which the minimum effectiveness was proposed, lispro, glargine and detemir were dominant strategies. Sensitivity analysis showed that the aspart had R$ 3,066.98 [95 % CI: 2339.22; 4418.53] and detemir had R$ 6,163.97 [95% CI: 3919.29; 11401.57] for incremental costs. We concluded there was evidence that the insulin aspart is the most cost-effective.

Adherence and/or discontinuation of imatinib mesylate in patients with chronic myeloid leukemia

ABSTRACT Adherence to imatinib mesylate improves clinical outcomes and promotes a reduction in health expenditure. However, treatment duration and lack of efficacy decrease adherence to pharmacotherapy, resulting in increased mortality associated with Chronic Myeloid Leukemia. This study aimed to evaluate and compare adherence and/or discontinuation of imatinib mesylate in different studies from the literature. An integrative review of original articles published between the years of 2004 and 2014 was performed using the databases PubMed/MEDLINE, Scopus and SciELO. The descriptor "imatinib" was used in two combinations employing the connector AND between terms: "medication adherence'' AND ''imatinib" AND "leukemia'' and ''patient compliance'' AND "imatinib" AND "leukemia". We identified 476 studies, being 14 included in the study. The rates of adherence and discontinuation were diverse, ranging from 19.0 to 97.0% and from 1.8 and 41.0%, respectively, and a high number of longitudinal studies was observed (71.4%). Most studies used questionnaires as an indirect method to assess adherence and factors related to poor adherence were adverse drug reactions, dose changes and unavailability of the medication. Patient education associated with follow up by pharmacists and other health professionals can improve patient adherence and minimize the pharmacotherapy discontinuation.

Efficacy and Tolerability of Antiepileptic Drugs in Patients with Focal Epilepsy: Systematic Review and Network Meta-analyses.

Several newer antiepileptic drugs (AEDs) have been introduced into clinical practice, offering choices for individualizing the treatment of epilepsy since AEDs have different efficacy and tolerability profiles. In particular, questions exist regarding which AEDs are the best options for the monotherapy of focal epilepsy. Is carbamazepine (CBZ), which is considered the standard treatment for focal epilepsy, still the best option for monotherapy of focal epilepsy, despite the emergence of new AEDs? In this systematic review, we compared the relative tolerability of all available AEDs for monotherapy of all types of epilepsy as well as their efficacy in the monotherapy of focal epilepsy. In addition, we compared CBZ with other AEDs for the monotherapy of focal epilepsy. We performed a search of the MEDLINE/PubMed, Scopus, Web of Science, and Cochrane Central Register of Controlled Trials (CENTRAL) databases for randomized controlled clinical trials. To compare the relative efficacy and tolerability of the AEDs, we performed network meta-analyses using a Bayesian random-effects model. Sensitivity analyses were conducted to determine the robustness of the results. A total of 65 studies were included in this review, composing 16,025 patients. Clobazam, levetiracetam, lamotrigine, oxcarbazepine, sulthiame, topiramate, and valproate had the best efficacy profiles and demonstrated no evidence of superiority or inferiority compared with CBZ. However, CBZ showed the greatest risk of patient discontinuation due to intolerable adverse reactions, whereas lamotrigine had the best safety profile and an 81% probability of being the best for the tolerability outcome of patient withdrawals from the study due to intolerable adverse reactions, followed by sulthiame (60%) and clobazam (51%). The newer AEDs-levetiracetam, lamotrigine, oxcarbazepine, sulthiame, and topiramate-should be considered for monotherapy of focal epilepsy because they were demonstrated to be as effective as the older ones (CBZ, clobazam, and valproate) for the treatment of focal epilepsy and were more tolerable. Lamotrigine was the AED with the best tolerability profile, suggesting that it may be the best option for the treatment of focal epilepsy in children and adults.

The aim of this study was to analyze the access to pharmaceutical services by the elderly provided by the Unified Health System in the municipality of Ribeirão Preto - SP, Brazil, as well as their knowledge about the correct form of using the prescribed medication. A crosssectional study was performed with elderly patients aged 60 years and older in the moment that they withdrawal their medications at a public pharmacy in the municipality of Ribeirão Preto - SP. A standardized form was used for data collection performed between November 2008 and May 2009. We interviewed 1000 elderly, of which less than half (46.8%) acquired all the medications contained in the prescription through the Unified Health System. In addition, 31.3% of the interviewees did not acquired the prescribed medication by a lack of at least one medication in the standardized list of the municipality. More than 87.4% of the elderly claimed they did not receive guidance from the pharmacist in the moment of drug dispensing, 37.1% reported a lack of knowledge of the correct dosage form of the medications used and 62,2% of the elderly interviewed stopped using the prescribed medication once during the treatment period. It is noteworthy that 15.8% of the respondents have also private health insurance. Access barriers to prescribed medication and the lack of knowledge about the dosage highlight deficiencies with respect to pharmaceutical services offered by the Unified Health System of Ribeirão Preto - SP...

Bothrops snake venoms and their isolated toxins, an L-amino acid oxidase and a serine protease, modulate human complement system pathways.

BACKGROUND: Activation of the complement system plays an important role in the regulation of immune and inflammatory reactions, and contributes to inflammatory responses triggered by envenomation provoked by Bothrops snakes. The present study aimed to assess whether Bothrops jararacussu and Bothrops pirajai crude venoms and their isolated toxins, namely serine protease (BjussuSP-I) and L-amino acid oxidase (BpirLAAO-I), modulate human complement system pathways. METHODS: Lyophilized venom and toxin samples solubilized in phosphate buffered saline were diluted in appropriate buffers to evaluate their hemolytic activity on the alternative and classical pathways of the complement system. Venom- and toxin-treated normal human serum was added to the erythrocyte suspension, and the kinetic of hemolysis was measured spectrophotometrically at 700 nm. The kinetic 96-well microassay format was used for this purpose. We determined the t(½) values (time required to lyse 50 % of target erythrocytes), which were employed to calculate the percentage of inhibition of the hemolytic activity promoted by each sample concentration. To confirm complement system activation, complement-dependent human neutrophil migration was examined using the Boyden chamber model. RESULTS: At the highest concentration tested (120 µg/mL), B. jararacussu and B. pirajai crude venoms inhibited the hemolytic activity of the classical pathway (65.3 % and 72.4 %, respectively) more strongly than they suppressed the hemolytic activity of the alternative pathway (14.2 and 13.6 %, respectively). BjussuSP-I (20 µg/mL) did not affect the hemolytic activity of the classical pathway, but slightly decreased the hemolytic activity of the alternative pathway (13.4 %). BpirLAAO-I (50 µg/mL) inhibited 24.3 and 12.4 % of the hemolytic activity of the classical and alternative pathways, respectively. Normal human serum treated with B. jararacussu and B. pirajai crude venoms induced human neutrophil migration at a level similar to that induced by zymosan-activated normal human serum. CONCLUSION: Together, the results of the kinetics of hemolysis and the neutrophil chemotaxis assay suggest that pre-activation of the complement system by B. jararacussu and B. pirajai crude venoms consumes complement components and generates the chemotactic factors C3a and C5a. The kinetic microassay described herein is useful to assess the effect of venoms and toxins on the hemolytic activity of the complement system.
