ABSTRACT BACKGROUND: Despite the several options available for supplements containing vitamins C and E, evidence regarding the prevalence of deficiency or insufficiency of these vitamins is weak. OBJECTIVES: To estimate the prevalence of deficiency or insufficiency of vitamins C and E and associated factors among women of childbearing age, in Brazil. DESIGN AND SETTING: Systematic review and meta-analysis conducted at a Brazilian public university. METHODS: A search from index inception until May 2020 was conducted. Meta-analyses were performed using inverse variance for fixed models, with summary proportions calculation using Freeman-Tukey double arcsine (base case). Reporting and methodological quality were assessed using the Joanna Briggs Institute tool for prevalence studies. RESULTS: Our review identified 12 studies, comprising 1,316 participants, especially breastfeeding women. There was at least one quality weakness in all studies, mainly regarding sampling method (i.e. convenience sampling) and small sample size. The prevalence of vitamin C deficiency ranged from 0% to 40%. Only vitamin E deficiency was synthetized in meta-analyses, with mean prevalences of 6% regardless of the alpha-tocopherol cutoff in plasma, and 5% and 16% for cutoffs of < 1.6-12.0 mmol/l and < 16.2 mmol/l, respectively. The cumulative meta-analysis suggested that a trend to lower prevalence of vitamin E deficiency occurred in recent studies. CONCLUSIONS: Although the studies identified in this systematic review had poor methodological and reporting quality, mild-moderate vitamin C and E deficiencies were identified, especially in breastfeeding women. Thus, designing and implementing policies does not seem to be a priority, because the need has not been properly dimensioned among women of childbearing age in Brazil.

Objective: To map the clinical pharmacy services conducted in Brazil, their characteristics, outcomes, and process measures in general population, as well as the assessment of the clinical impact on people with cardiometabolic diseases (cardiovascular diseases and metabolic diseases). Methods: A systematic scoping review and meta-analysis were conducted. The electronic searches were re-run in March 2020. To the clinical impact assessment, meta-analyses of cardiometabolic outcomes (i.e., change of systolic (SBP) and diastolic blood pressure (DBP), triglycerides, total cholesterol, glycated hemoglobin (HbA1c), fasting glycemia, LDL-, and HDL-cholesterol) were led. The risk of bias was assessed with the Cochrane Collaboration tools. Results: 71 studies were identified (7,402 patients), being the majority quasi-experimental studies (n=41) and published by research groups of Southeast Brazil (n=33). Medication therapy management (n=62) was the most frequent clinical pharmacy service, performed on outpatient setting (n=45), with adults or elderly people (n=58) with hypertension (n=18) or diabetes (n=10). Process measures (n=58) (e.g. resolution of drug related-problem) were widely used as indicator, followed by clinical (n=44) (e.g. change in SBP), humanistic (n=12) (e.g. change in quality-of-life score assessed by Short-Form 36 Health Survey Questionnaire), and economic outcomes (n=3) (incremental cost-effectiveness ratio for reduction in HbA1c). Regarding the assessment of clinical impact of the services, 20 studies were included in meta-analyses, showing improvement in most cardiometabolic outcomes when considered individual studies. However, the evidence presents high risk of bias, high heterogeneity (median 67-90%) and imprecision, contributing to wide prediction intervals and low reliability. Conclusions: A predominance of studies on cardiometabolic diseases, process measures, and clinical outcomes were identified. Considering the assessment of the clinical impact of clinical pharmacy services in cardiometabolic diseases, an improvement in most cardiometabolic outcomes was showed, however, with low confidence and wide prediction interval. Therefore, development of larger studies with low risk of bias and major homogeneity is necessary for a better comprehension of clinical pharmacy service characteristics, benefits, and the population groups most benefited.

Abstract Background: Although the management of hyperkalemia follows expert guidelines, treatment approaches are based on traditionally accepted practice standards. New drugs have been assessed such as sodium zirconium cyclosilicate and patiromer; however, their safety and efficacy or effectiveness have not yet been compared to traditional pharmacotherapy. Objective: The present systematic review had the purpose to evaluate the efficacy, effectiveness, and safety of hyperkalemia pharmacotherapies. Methods: PubMed, LILACS, Cochrane Library, and ClinicalTrials were searched through November 2018. Clinical trial, cohort and case-control were searched. The risk of bias (RoB v2.0 and ROBINS-I) and quality of evidence (GRADE) at the level of outcomes were assessed. Results: Sixteen clinical trials and one retrospective cohort were identified regarding efficacy and safety of 24 different alternatives. The management of hyperkalemia remains empirical and off-label, since sodium zirconium cyclosilicate and patiromer are not available in several countries and further studies are required to assess efficacy, effectiveness and safety. Sodium or calcium polystyrene sulfonate (moderate confidence), sodium zirconium cyclosilicate (moderate confidence), and insulin plus dextrose (moderate confidence) showed superior efficacy to, respectively, placebo, no treatment, placebo, and dextrose. Other therapies (low confidence) showed similar efficacy compared to active or inactive alternatives. Most of the adverse events reported were nonspecific, so it was not possible to assign the cause and to classify as defined or probable. Conclusions: Comparative cohort and case-control studies are need to evaluate the safety and effectiveness of new and traditional pharmacotherapies to support the development of guidelines about acute and chronic hyperkalemia, with high-quality evidence.

O objetivo do estudo foi descrever as figuras humanas retratadas nas propagandas de medicamentos psicoativos quanto ao gênero, a idade, a etnia e o contexto social. Foi realizada análise de conteúdo de 86 impressos publicitários inéditos divulgados em Araraquara (SP) no ano de 2005. A associação entre as categorias foi analisada usando o teste exato de Fisher. Houve predomínio de mulheres (62,8%), sendo quatro vezes mais freqüentes que os homens em propagandas de antidepressivos e ansiolíticos. A maioria era constituída de jovens adultos (72%), de etnia branca (98,8%). As pessoas estavam em lazer (46,5%), em suas casas (29%) ou em contato com a natureza (16,2%). A mensagem transmitida foi que os medicamentos tratam sintomatologias subjetivas de desconforto do dia-a-dia, induzindo a um apelo irracional que pode refletir na prescrição medicamentosa.

The goal of this study was to describe the human figures portrayed in psychoactive drug advertising in terms of gender, age, ethnic group, and social context. Content analysis for 86 new pieces of printed advertisements released in 2005 was carried out. Fisher exact test was used to analyze the association between categories. There was a preponderance of women (62.8%) who were four times more present in advertisements for antidepressants and anxyolitics than men. Most of the people shown were Caucasian (98.8%) young adults (72%). These people were pictured in leisure activities (46.5%), at home (29%), or in contact with nature (16.2%). The message conveyed was that the drugs treat routinely felt subjective symptoms of discomfort, inducing in an irrational appeal that may affect drug prescription.

OBJETIVO: Segundo a Organização Mundial da Saúde, as propagandas de medicamentos devem ser fidedignas, exatas, verdadeiras, informativas, equilibradas, atualizadas e passíveis de comprovação. O objetivo do estudo foi avaliar as propagandas de medicamentos psicoativos divulgadas a médicos, em relação à concordância das informações contidas nas peças publicitárias com as suas respectivas referências bibliográficas e à acessibilidade dessas referências citadas. MÉTODOS: A coleta de dados foi realizada durante o ano de 2005, em Araraquara, SP. Foram coletadas e analisadas propagandas de 152 medicamentos, num total de 304 referências. As referências bibliográficas foram solicitadas aos serviços de atendimento ao cliente dos laboratórios e consultadas nas bibliotecas da rede UNESP (Ibict, Athenas), BIREME (SciELO, PubMed, periódicos catalogados de acesso livre) e periódicos CAPES. As afirmações das propagandas foram conferidas com as das referências por meio da técnica de análise de conteúdo. RESULTADOS: Das referências citadas nas propagandas, 66,7% foram acessadas. De 639 afirmações identificadas, foi possível analisar 346 (54%). Verificou-se que 67,7% das afirmações das propagandas conferiam com suas referências e as demais não conferiam ou conferiam parcialmente. Entre as propagandas analisadas, foi observada média de 2,5 (1-28) referências citadas por propaganda. No corpo das propagandas, foram identificadas 639 informações que estavam explicitamente associadas à pelo menos uma das referências citadas (média de 3,5 informações por propaganda). CONCLUSÕES: Os resultados evidenciaram a dificuldade de acesso às referências. As mensagens de eficácia, segurança, custos, entre outras, nem sempre estão respaldadas por estudos científicos. São necessárias mudanças nas exigências legais e fiscalização efetiva das promoções de medicamentos.

OBJECTIVE: According to the World Health Organization, medicinal drug promotion should be reliable, accurate, truthful, informative, balanced, up-to-date and capable of substantiation. The objective of the present study was to review psychoactive drug advertisements to physicians as for information consistency with the related references and accessibility of the cited references. METHODS: Data was collected in the city of Araraquara, Southeastern Brazil, in 2005. There were collected and reviewed 152 drug advertisements, a total of 304 references. References were requested directly from pharmaceutical companies' customer services and searched in UNESP (Ibict, Athenas) and BIREME (SciELO, PubMed, free-access indexed journals) library network and CAPES journals. Advertisement statements were checked against references using content analysis. RESULTS: Of all references cited in the advertisements studied, 66.7% were accessed. Of 639 promotional statements identified, 346 (54%) were analyzed. The analysis showed that 67.7% of promotional statements in the advertisements were consistent with their references, while the remaining was either partially consistent or inconsistent. Of the material analyzed, an average 2.5 (1-28) references was cited per advertisement. In the text body, there were identified 639 pieces of information clearly associated with at least one cited reference (average 3.5 pieces of information per advertisement). CONCLUSIONS: The study results evidenced difficult access to the references. Messages on efficacy, safety and cost, among others, are not always supported by scientific studies. There is a need for regulation changes and effective monitoring of drug promotional materials.

OBJETIVOS: Analisar a prescrição e dispensação de medicamentos psicotrópicos por meio da análise das receitas/notificações retidas em diferentes estabelecimentos de dois municípios do estado de São Paulo. MÉTODOS: Em parceria com as Vigilâncias Sanitárias dos municípios, foram coletadas e analisadas as prescrições retidas em drogarias, farmácias de manipulação, postos públicos e hospitais no ano de 1999. Os dados contidos nas receitas/notificações foram digitados e tabulados. RESULTADOS: Foram processadas 108.215 prescrições, sendo 76.954 de benzodiazepínicos, 26.930 de anorexígenos, 3.540 de opiáceos e 788 de outros. Os benzodiazepínicos mais freqüentes foram: diazepam (31.644), bromazepam (16.911) e clonazepam (7.929) e, entre os anorexígenos, dietilpropiona (14.800) e femproporex (10.942). As mulheres, em geral, receberam mais prescrições em comparação com os homens, especialmente para os anorexígenos, com uma relação dez vezes maior nas prescrições de dietilpropiona e femproporex. As poucas farmácias de manipulação (n=6) chegaram a movimentar mais prescrições do que as drogarias (n=49). Também foi detectada uma série de erros e incoerências nas prescrições analisadas. CONCLUSÕES: Os resultados confirmam a ocorrência de uso irracional e uma série de práticas inadequadas que envolvem a prescrição desses medicamentos no Brasil e, portanto, indicam a necessidade de uma ampla revisão no atual sistema de controle dessas substâncias no país.

OBJECTIVES: To investigate the prescription and dispensation of psychotropic medications through the analysis of the prescriptions/notices kept at various institutions in two cities in the state of São Paulo. METHODS: The prescriptions kept at drugstores, magistral pharmacies, primary care settings and hospitals were collected and analyzed in collaboration with the Sanitary Vigilance agencies in the year of 1999. The information in the prescriptions/notices were typed and tabulated. RESULTS: A total of 108,215 prescriptions were processed, being 76,954 for benzodiazepines, 26,930 for anorexigenic drugs, 3,540 for opiates and 788 for other drugs. The benzodiazepines most frequently prescribed were: diazepam (31,644), bromazepam (16,911) and clonazepam (7,929). Among the anorexigenic drugs, diethylpropion (14,800) and femproporex (10,942) were the most common. When compared to men, women were given more prescriptions, mainly for anorexigenic drugs: the ratio was 10:1 in the prescriptions for diethylpropion and femproporex. The few magistral pharmacies (n=6) handled even more prescriptions than did the drugstores (n=49). A number of errors and inconsistencies were detected in the prescriptions analyzed. CONCLUSIONS: The results confirm the occurrence of an irrational use of such medications and a series of inadequate practices related to their prescription in Brazil. Therefore, they point out to the need of a comprehensive review of the government's control system of these substances.

Descrevem-se pacientes com glomerulonefrites (GNs) associadas à infecção pelo vírus da hepatite C (HCV). Entre agosto de 93 e julho de 96 foram observados 4 pacientes, com idade mediana de 41 anos, sendo 2 do sexo masculino. Pesquisaram-se o anti-HCV por ensaio imuno-enzimático e o HCV-RNA por PCR. Também foram pesquisadas crioglobulinas séricas, hemácias dismórficas no sedimento urinário e proteinúria de 24h. Viremia, crioglobulinas, hematúria e proteinúria foram observadas nos 4 pacientes. As biópsias hepáticas revelaram atividade inflamatória nos 3 pacientes em que foram realizadas e as do rim revelaram glomerulonefrite membranoproliferativa em 3 e glomerulonefrite proliferativa mesangial em 1 paciente. Dois pacientes vêm recebendo antivirais (IFN associado à ribavirina) e evoluindo com melhora. A presença de viremia e de hepatite concomitante com as alterações urinárias constituem indícios do envolvimento viral na glomerulopatia. Tais achados são reforçados pela melhora das alterações urinárias durante o tratamento específico. Conclui-se que a pesquisa de marcadores virais em pacientes com GNs assume relevância na medida em que pode modificar a conduta terapêutica.

We report 4 patients with glomerulonephritis (GN) associated with hepatitis C virus (HCV) infection seen between August 1993 and July 1996. Two of them were male and median age was 41 years. Anti-HCV was detected by enzyme-immunoassay and HCV-RNA by PCR. Serum cryoglobulins, 24-hour proteinuria, and erythrocyte dismorphism were also determined. Viremia, cryoglobulinemia, hematuria and proteinuria were observed in all patients. Liver biopsies revealed inflammatory activity in 3 cases, and renal biopsies revealed membranoproliferative glomerulonephritis in 3 patients and mesangial proliferative glomerulonephritis in 1 patient. Two patients are on specific therapy for HCV infection (IFN in combination with ribavirin) and have presented clinical and laboratory improvement. The occurrence of active liver disease and viremia concurrent with urinary alterations suggests viral involvement in renal disease, a conclusion supported by the by improvement of urinary alterations observed after treatment for HCV. We conclude that the search for viral markers in patients with GN is important since their detection could change the therapeutic approach.
