Brazilian scientific production on pharmaceutical care from 1990 to 2009

Brazilian scientific production on pharmaceutical care was identified based on articles indexed on the Medline, Embase, Lilacs, Web of Science and International Pharmaceutical Abstracts databases. Sixty-three articles published in both national and international journals were retrieved. With regard to authors, 72.3% were from the Southeast and South Regions, and 60.8% were affiliated to public universities. In relation to the type of studies, 85.7% were descriptive, and the most frequently researched fields were community pharmacies, hospitals and primary health care units. Articles were original in 65.1% of cases, updates in 20.6%, and reviews in 7.9%. An increase in publications commenced in 2006. In 31.7% of cases, authors had adopted a bibliographical study design, 28.6% qualitative study, 23.8% intervention, and 15.9% observational study design. The most researched subjects were elderly with chronic diseases. The importance of stimulating the conducting of experimental and qualitative studies, as well as amplifying authorship affiliated with the service area, foreign authors and with research in a wide variety of practice settings were highlighted. Despite the limited quantity of articles, an increase in their number as well as in their scope and quality is expected, so as to create further knowledge that contributes to the recognition of pharmacists' actions by patient healthcare teams.

The Pharmaceutical care of patients with type 2 diabetes mellitus

Objective To evaluate the efficiency of pharmaceutical care on the control of clinical parameters, such as fasting glycaemia and glycosylated haemoglobin in patients with Type 2 Diabetes mellitus. Setting This study was conducted at the Training and Community Health Centre of the College of Medicine of Ribeirao Preto, University of Sao Paulo, Brazil. Methods A prospective and experimental study was conducted with 71 participants divided in two groups: (i) pharmaceutical care group (n=40), and (ii) the control group (n=31). The distribution of patients within these groups was made casually, and the patients were monitored for 12 months. Main outcome measure: Values for fasting glycaemia and glycosylated haemoglobin were collected. Results Mean values of fasting glycaemia in the pharmaceutical care group were significantly reduced whilst a small reduction was detected in the control group at the same time. A significant reduction in the levels of glycosylated haemoglobin was detected in patients in the pharmaceutical care group, and an average increase was observed in the control group. Furthermore, the follow-up of the intervention group by a pharmacist contributed to the resolution of 62.7% of 142 drug therapy problems identified. Conclusion In Brazil, the information provided by a pharmacist to patients with Type 2 Diabetes mellitus increases compliance to treatment, solving or reducing the Drug Therapy Problem and, consequently, improving glycaemic control.

Effect of a 36-month pharmaceutical care program on pharmacotherapy adherence in elderly diabetic and hypertensive patients

Objective: The primary objective of this study was to evaluate the effect of a pharmaceutical care program on pharmacotherapy adherence in elderly diabetic and hypertensive patients. The clinical outcomes of this pharmacotherapy adherence approach were the secondary objective of the study. Setting: Public Primary Health Care Unit in a municipality in the Brazilian State of Sao Paulo. Method: A 36-month randomized, controlled, prospective clinical trial was carried out with 200 patients divided into two groups: control (n = 100) and intervention (n = 100). The control group received the usual care offered by the Primary Health Care Unit (medical and nurse consultancies). The patients randomized into the intervention group received pharmaceutical care intervention besides the usual care offered. Main outcome measure: Pharmacotherapy adherence (Morisky-Green test translated into Portuguese and computerized dispensed medication history) and clinical measurements (blood pressure, fasting glucose, A1C hemoglobin, triglycerides and total cholesterol) were evaluated at the baseline and up to 36 months. A P value < 0.05 was considered statistically significant. Results: A total of 97 patients from the intervention group and 97 patients from the control group completed the study (n = 194). Significant improvements in the pharmacotherapy adherence were verified for the intervention group according to the Morisky-Green test (50.5% of adherent patients at baseline vs. 83.5% of adherent patients after 36 months; P < 0.001) and the computerized dispensed medication history (52.6% of adherent patients at baseline vs. 83.5% of adherent patients after 36 months; P < 0.001); no significant changes were verified in the control group. Significant improvements in the number of patients reaching adequate values for their blood pressure (26.8% at baseline vs. 86.6% after 36-months; P < 0.001), fasting glucose (29.9% at baseline vs. 70.1% after 36 months; P < 0.001), A1C hemoglobin (3.3% at baseline vs. 63.3% after 36 months; P < 0.001), triglycerides (47.4% at baseline vs. 74.2% after 36 months; P < 0.001) and total cholesterol (59.8% at baseline vs. 80.4% after 36 months; P = 0.002) were verified in the intervention group, but remained unchanged in the control group. Conclusion: These results indicated the effectiveness of pharmaceutical care in improving pharmacotherapy adherence, with positive effects in the clinical outcomes of the patients studied.

Controle judicial da política de assistência farmacêutica: direito, ciência e técnica

Para identificar mecanismos de compatibilização entre a lei e as normas técnicas, foram considerados o conceito de saúde e as características do Estado Democrático de Direito. Tomando-se o exemplo brasileiro das normas da política de assistência farmacêutica, concluiu-se que racionalidade jurídica impõe verificar se sua elaboração obedeceu ao requisito constitucional que exige a "participação da comunidade", instaurando um controle democrático e judicial.

Atenção farmacêutica em farmácias e drogarias: existe um processo de mudança?

Para se conhecer a prática profissional de farmacêuticos que atuam em farmácias e drogarias, seus conhecimentos e percepções acerca da Atenção Farmacêutica (AF), realizou-se estudo descritivo com 91 farmacêuticos do município de Jundiaí-SP. A maioria era jovem (62,6% entre 20 e 29 anos), do sexo feminino (63,7%), graduada em instituições privadas (90,1%) e não proprietária do estabelecimento (87,9%). Desenvolviam atividades administrativas, técnicas e de atenção ao usuário, principalmente dispensação de medicamentos e orientação; 67,0% acompanhavam o tratamento farmacoterapêutico dos usuários, mas sem registrar informações. Para 62,7%, AF relacionava-se apenas à orientação e atendimento dispensados, mas tais atividades não eram realizadas de forma sistemática e organizada, como preconizado. Muitos (91,2%) consideravam necessário realizar trabalho mais intenso com os usuários, porém apontaram dificuldades como falta de tempo e de apoio dos proprietários e desinteresse dos usuários. Várias dessas dificuldades têm sido verificadas também em outros países, sugerindo que a prática da AF: (a) requer uma mudança estrutural e rearranjo de funções, uma vez que, atualmente, a estrutura e as atividades são adequadas à atividade comercial; (b) reflete uma crise de identidade profissional e, em consequência, falta de reconhecimento social e pouca inserção na equipe multiprofissional de saúde. O conhecimento sobre AF mostrou-se limitado, mas a situação pode vir a alterar-se à medida que as mudanças curriculares em curso surtam efeito na formação dos novos farmacêuticos.

Um enfoque sanitário sobre a demanda judicial de medicamentos

No Brasil, apesar dos avanços da assistência farmacêutica, permanecem falhas na garantia do acesso dos cidadãos aos medicamentos pelo Estado. Nos últimos anos, vem crescendo a reivindicação de medicamentos por parte do cidadão via sistema judiciário. Os objetos dessas solicitações são tanto os medicamentos em falta na rede pública como aqueles ainda não incorporados pelo Sistema Único de Saúde. Este fenômeno pode ser analisado sob diferentes perspectivas, inclusive a sanitária, entendida aqui como os desfechos sobre a saúde dos indivíduos que demandam estes medicamentos. O presente texto busca discutir as principais características das demandas judiciais frente aos seguintes aspectos: o uso racional de medicamentos, o uso de evidências científicas para a indicação terapêutica proposta e o quanto as demandas se justificam diante do conceito de acesso adotado pelo campo da assistência farmacêutica. Ponderações podem ser feitas no sentido de minimizar os riscos à saúde dos demandantes de medicamentos por via judicial, sobretudo quando o objeto da ação são medicamentos não pertencentes às listas de fornecimento público, ou com uso off label, ou desprovidos de registro no país. Considera-se que o Judiciário, a partir do fornecimento de medicamentos, busca garantir a saúde dos demandantes, e assim a dignidade da pessoa humana. Cabe ressaltar que este objetivo só será atingido quando a garantia da saúde estiver associada aos aspectos que certificam a segurança do paciente, inclusive no uso de medicamentos.

Terminologia de incidentes com medicamentos no contexto hospitalar

Incidentes com medicamentos geram problemas aos pacientes e custos adicionais ao sistema de saúde. A variedade de termos utilizada para comunicá-los propicia divergências nos resultados de pesquisas e confundem notificadores. Objetivou-se revisar os termos utilizados para descrever estes incidentes confrontando-os com as conceituações/definições oficiais disponíveis. Pesquisaram-se as bases PubMed, MEDLINE, IPA e LILACS para selecionar estudos publicados entre janeiro de 1990 e dezembro de 2005. Selecionaram-se 33 publicações. Verificou-se que a terminologia supranacional recomendada para descrever incidentes com medicamentos é insuficiente, mas que há consenso de uso das expressões em função do gênero do incidente. O termo Reação Adversa a Medicamento é mais utilizado quando não se verifica intencionalidade. A expressão Evento Adverso a Medicamento foi mais usada quando se descreviam incidentes durante a hospitalização; e Problema Relacionado a Medicamento foi mais utilizada em estudos que avaliaram atenção/cuidados farmacêuticos (uso/falta do medicamento). Ainda assim, a linha divisória entre essas três categorias não é clara e simples. Futuros estudos das relações entre as categorias e investigações multidisciplinares sobre erro humano podem subsidiar a proposição de novas conceituações

Knowledge and information flows in supply chains: A study on pharmaceutical companies

A great deal of attention in the supply chain management literature is devoted to study material and demand information flows and their coordination. But in many situations, supply chains may convey information from different nature, they may be an important channel companies have to deliver knowledge, or specifically, technical information to the market. This paper studies the technical flow and highlights its particular requirements. Drawing upon a qualitative field research, it studies pharmaceutical companies, since those companies face a very specific challenge: consumers do not have discretion over their choices, ethical drugs must be prescribed by physicians to be bought and used by final consumers. Technical information flow is rich, and must be redundant and early delivered at multiple points. Thus, apart from the regular material channel where products and order information flow, those companies build a specialized information channel, developed to communicate to those who need it to create demand. Conclusions can be extended to supply chains where products and services are complex and decision makers must be clearly informed about technology-related information. (C) 2009 Elsevier B.V.

Oral findings and dental care in a patient with myelomeningocele: case report of a 3-year-old child

Myelomeningocele (MMC) is a congenital malformation of the neural tube that occurs in the first weeks of pregnancy. This malformation refers to the caudal non-closure of the neural tube and neural tissue exposure, which lead to neurological problems, such as hydrocephalus, motor disability, genitourinary tract and skeletal abnormalities and mental retardation. Patients with MMC have an acknowledged predisposition to latex allergy and are usually at a high caries risk and activity due to poor oral hygiene, fermentable carbon hydrate-rich diet and prolonged use of sugar-containing medications. This paper addresses the common oral findings in pediatric patients with MMC, discusses the strategies and precautions to deal with these individuals and reports the dental care to a young child diagnosed with this condition.

Fatal adenoviral necrotizing bronchiolitis case in a post-cardiac surgery intensive care unit

We report a case of a 67 year-old-male patient admitted to the intensive care unit in the post-coronary bypass surgery period who presented cardiogenic shock, acute renal failure and three episodes of sepsis, the latter with pulmonary distress at the 30th post-operative day. The patient expired within five days in spite of treatment with vancomycin, imipenem, colistimethate and amphotericin B. At autopsy severe adenovirus pneumonia was found. Viral pulmonary infections following cardiovascular surgery are uncommon. We highlight the importance of etiological diagnosis to a correct treatment approach.

Recalled and recorded bowel habits confirm early onset and high frequency of constipation in day-care nursery children

CONTEXT: Mothers recall early-onset constipation in children attending gastroenterology clinics. OBJECTIVES: To study the bowel habit of young children in the community to determine, first, whether early-onset constipation is confirmed in this setting and, second, the agreement between recalled and recorded bowel habit. METHODS:Defecation data of 57 children aged 6.0-40.7 mo were obtained by maternal recall (questionnaire on predominant stool characteristics) and by record (1,934 defecations registered prospectively at home and in the nursery). The bowel habit was classified according to stool frequency and proportion of stool characteristics (soft, hard and/or runny). Two criteria were used to classify recorded data, since the cutoff point for hard stools to identify constipation is undefined in children: predominant criterion and adult criterion, respectively with >50% and >25% of stools with altered consistency. Bowel habit categories were: adequate, constipation, functional diarrhea and "other bowel habit". Nonparametric statistics, and the Kappa index for agreement between recalled and recorded bowel habit, were used. RESULTS: Constipation occurred in 17.5%, 10.5%, 19.3% of the children by recall, the predominant and the adult criteria, respectively. Constipation was the main recalled alteration, vs 12.3% "other bowel habit". Only one child classified as having functional diarrhea (by the adult criterion). Agreement between recalled and recorded bowel habit was fair for constipation, by the predominant and the adult criteria (K = 0.28 and 0.24, respectively), but only slight (K <0.16) for other bowel habit categories. Individual data, however, pointed to a better relationship between recalled constipation and the adult rather than the predominant criterion. CONCLUSIONS: Frequent early-onset constipation was confirmed. Fair agreement between recalled and recorded constipation by the two used criteria indicates that recalled data are quite reliable to detect constipation.

First cases of exclusive paternal care in stink bugs (Hemiptera: Pentatomidae)

We describe paternal care in two pentatomid bugs, Lopadusa (Lopadusa) augur Stål, 1860 and Edessa nigropunctata Berg, 1884. Field and laboratory observations showed that males remain with their eggs and early hatched nymphs, while females abandon the eggs after oviposition. Guarding males defensive behaviors towards their clutches were similar to those described for guarding females of pentatomids. Since there is no detailed information on the internal phylogeny of Pentatomidae, it is not possible to make a robust inference on whether paternal care in L. augur and E. nigropunctata has arisen independently or not. If the latter, the two new cases of paternal care we describe here represent the fifth event of independent evolution of this rare behavioral trait in Heteroptera.

Determination of 5-aminosalicylic acid in pharmaceutical formulations by square wave voltammetry at pencil graphite electrodes

An analytical method for the determination of the anti-inflammatory drug 5-aminosalicylic acid (5-ASA) in pharmaceutical formulations using square wave voltammetry at pencil graphite electrodes was developed. After the optimization of the experimental conditions, calibration curves were obtained in the linear concentration range from 9.78 × 10-7 to 7.25 × 10-5 mol L-1 resulting in a limit of detection of 2.12 ± 0.05 x 10-8 mol L-1. Statistical tests showed that the concentrations of 5-ASA in commercial tablets and enemas obtained with the proposed voltammetric method agreed with HPLC values at a 95% confidence level.

Self-disclosure of HIV diagnosis to sexual partners by heterosexual and bisexual men: a challenge for HIV/AIDS care and prevention

This study investigated the disclosure of HIV-positive serostatus to sexual partners by heterosexual and bisexual men, selected in centers for HIV/AIDS care. In 250 interviews, we investigated disclosure of serostatus to partners, correlating disclosure to characteristics of relationships. The focus group further explored barriers to maintenance/establishment of partnerships and their association with disclosure and condom use. Fear of rejection led to isolation and distress, thus hindering disclosure to current and new partners. Disclosure requires trust and was more frequent to steady partners, to partners who were HIV-positive themselves, to female partners, and by heterosexuals, occurring less frequently with commercial sex workers. Most interviewees reported consistent condom use. Unprotected sex was more frequent with seropositive partners. Suggestions to enhance comprehensive care for HIV-positive men included stigma management, group activities, and human rights-based approaches involving professional education in care for sexual health, disclosure, and care of "persons living with HIV".

The use of a graphite-silicone rubber composite electrode in the determination of rutin in pharmaceutical formulation

The possibility of using a graphite silicone-rubber composite electrode (GSR) in a differential pulse voltammetric(DPV) procedure for rutin (vitamin P) determination is described. Cyclic voltammograms of rutin presented a reversible pair of oxidation/reduction peaks respectively at 0.411 and 0.390 V (vs. SCE) at the GSR surface in Britton-Robinson(B-R) buffer solution pH 4.0. In DPV after optimization of conditions, an oxidation peak at 0.370 V (vs. SCE) was used to quantitative determination of rutin in B-R buffer solution pH 4.0. In this case a linear dynamic range of 5.0×10-8 to 50.0×10-8 mol L-1 was observed with a detection limit of 1.8×10-8 mol L-1 for the analyte. Recoveries from 94 to 113% were observed. The electrode surface was renewed by polishing after each determination, with a repeatability of 1.09 ± 0.06 µA (n = 10) peak current. Rutin was determined in a pharmaceutical formulation using the proposed electrode and the results agreed with those from an official method within 95% confidence level.
