RESUMEN

BACKGROUND: The costs of developing new treatments and bringing them to the market are substantial. The pharmaceutical industry uses drug promotion to gain a competitive market share, and drive sale volumes and industry profitability. This involves disseminating information about new treatments to relevant targets. However, conflicts of interest can arise when profits are prioritised over patient care and its benefits. Drug promotion regulations are complex interventions that aim to prevent potential harm associated with these activities. OBJECTIVES: To assess the effects of policies that regulate drug promotion on drug utilisation, coverage or access, healthcare utilisation, patient outcomes, adverse events and costs. SEARCH METHODS: We searched Epistemonikos for related reviews and their included studies. To find primary studies we searched MEDLINE, CENTRAL, Embase, EconLit, Global Index Medicus, Virtual Health Library, INRUD Bibliography, two trial registries and two sources of grey literature. All databases and sources were searched in January 2023. SELECTION CRITERIA: We planned to include studies that assessed policies regulating drug promotion to consumers, healthcare professionals or regulators and third-party payers, or any combination of these groups.In this review we defined policies as laws, rules, guidelines, codes of practice, and financial or administrative orders made by governments, non-government organisations or private insurers. One of the following outcomes had to be reported: drug utilisation, coverage or access, healthcare utilisation, patient health outcomes, any adverse effects (unintended consequences), and costs. The study had to be a randomised or non-randomised trial, an interrupted time series analysis (ITS), a repeated measures (RM) study or a controlled before-after (CBA) study. DATA COLLECTION AND ANALYSIS: At least two review authors independently assessed eligibility for inclusion of studies. When consensus was not reached, any disagreements were discussed with a third review author.  We planned to use the criteria suggested by Cochrane Effective Practice and Organisation of Care (EPOC) to assess the risk of bias of included studies. For randomised trials, non-randomised trials, and CBA studies, we planned to estimate relative effects, with 95% confidence intervals (CI). For dichotomous outcomes, we planned to report the risk ratio (RR) when possible and adjusted for baseline differences in the outcome measures. For ITS and RM, we planned to compute changes along two dimensions: change in level and change in slope. We planned to undertake a structured synthesis following EPOC guidance.  MAIN RESULTS: The search yielded 4593 citations, and 13 studies were selected for full-text review. No study met the inclusion criteria. AUTHORS' CONCLUSIONS: We sought to assess the effects of policies that regulate drug promotion on drug use, coverage or access, use of health services, patient outcomes, adverse events, and costs, however we did not find studies that met the review's inclusion criteria. As pharmaceutical policies that regulate drug promotion have untested effects, their impact, as well as their positive and negative influences, is currently only a matter of opinion, debate, informal or descriptive reporting. There is an urgent need to assess the effects of pharmaceutical policies that regulate drug promotion using well-conducted studies with high methodological rigour.

RESUMEN

PURPOSE: Drug utilization research (DUR) contributes to inform policymaking and to strengthen health systems. The availability of data sources is the first step for conducting DUR. However, documents that systematize these data sources in Latin American (LatAm) countries are not known. We compiled the potential data sources for DUR in the LatAm region. METHODS: A network of DUR experts from nine LatAm countries was assembled and experts conducted: (i) a website search of the government, academic, and private health institutions; (ii) screening of eligible data sources, and (iii) liaising with national experts in pharmacoepidemiology (via an online survey). The data sources were characterized by accessibility, geographic granularity, setting, sector of the data, sources and type of the data. Descriptive analyses were performed. RESULTS: We identified 125 data sources for DUR in nine LatAm countries. Thirty-eight (30%) of them were publicly and conveniently available; 89 (71%) were accessible with limitations, and 18 (14%) were not accessible or lacked clear rules for data access. From the 125 data sources, 76 (61%) were from the public sector only; 46 (37%) were from pharmacy records; 43 (34%) came from ambulatory settings and; 85 (68%) gave access to individual patient-level data. CONCLUSIONS: Although multiple sources for DUR are available in LatAm countries, the accessibility is a major challenge. The procedures for accessing DUR data should be transparent, feasible, affordable, and protocol-driven. This inventory could permit a comparison of drug utilization between countries identifying potential medication-related problems that need further exploration.

RESUMEN

BACKGROUND: Parkinson's disease (PD) is a progressive multifactorial neurodegenerative condition. Epidemiological studies have shown that patients with type 2 diabetes mellitus (T2DM2) are at increased risk for developing PD, indicating a possible insulin-modulating role in this latter condition. We hypothesized that drugs similar to glucagon-like peptide-1 (GLP-1) and gastric inhibitory polypeptide (GIP), used in the treatment of T2DM2, may play a role in PD. OBJECTIVES: The purpose of this study is to systematically review and meta-analyze data of preclinical and clinical studies evaluating the efficacy and safety of GLP-1 and GIP drugs in the treatment of PD. METHODS: Two reviewers will independently evaluate the studies available in the Ovid Medline, Ovid Embase, Web of Science, Cochrane Central Register of Controlled Trials, Cinahl, and Lilacs databases. Preclinical rodent or non-human primate studies and randomized controlled human clinical trials will be included, without language or publication period restrictions. Outcomes of interest in preclinical studies will be primarily locomotor improvements and adverse effects in animal models of PD. For clinical trials, we will evaluate clinical improvements rated by the Movement Disorders Society Unified Parkinson's Disease Rating Scale-parts I, II, III, and IV, and adverse effects. The risk of bias of preclinical studies will be assessed by the SYRCLE tool and CAMARADES checklist and the clinical studies by the Cochrane tool; the certainty of the evidence will be rated by GRADE. DISCUSSION AND CONCLUSION: There is an urge for new PD treatments that may slow the progression of the disease rather than just restoring dopamine levels. This study will comprehensively review and update the state of the art of what is known about incretin hormones and PD and highlight the strengths and limitations of translating preclinical data to the clinic whenever possible.

RESUMEN

This investigation aimed to conduct a systematic review of the literature and meta-analysis to determine whether exposure to the herbicide paraquat was associated with the development of Parkinson's disease (PD). Observational studies that enrolled adults exposed to paraquat with PD as the outcome of interest were searched in the PubMed, Embase, LILACS, TOXNET, and Web of Science databases up to May 2019. Two authors independently selected relevant studies, extracted data, and assessed methodological quality. The evidence certainty was assessed by the GRADE approach, which served as basis for a tentative causality assessment, supplemented by the Bradford Hill criteria when necessary. Results from nine case-control studies indicated that PD occurrence was 25% higher in participants exposed to paraquat. The only cohort investigation included demonstrated a non-significant OR of 1.08. Results from subgroup analyses also indicated higher PD frequency in participants that were exposed to paraquat for longer periods or individuals co-exposed with paraquat and any other dithiocarbamate. Data indicate apositive association between exposure to paraquat and PD occurrence, but the weight-of-evidence does not enable one to assume an indisputable cause-effect relationship between these two conditions. Better designed studies are needed to increase confidence in results. Systematic Review Registration: PROSPERO CRD42017069994.

RESUMEN

Since the introduction of antibiotics, they have been used freely, with their prescription occurring almost always when they were not necessary. The other major form of contact between humans and antibiotics, now unintentionally, is with the large amount of these drugs in the environment and in our food. The relationship between antibiotic use and the development of obesity has become increasingly evident and apparent in humans, with some authors clearly establishing the relationship between the large-scale use of antibiotics in the past 70 years and the "epidemic" of obesity that has occurred in parallel, almost as an adverse epidemiological effect. In the research effort entertained herein, a correlation between the use and abuse of antibiotics and the onset of obesity was investigated.

RESUMEN

Brazil has had a National Essential Medicines List (EML) since 1964. From 2000 to 2010, five consecutive evidence-based editions were produced, building on the essential medicine concept. In 2012, the government changed course to establish a new paradigm, introducing adoption of new medicines as the main aim within the recommendation process. The objective of the article was to report efforts to develop Brazil's national EML, policy changes from 2000 to 2014, discussing results, challenges and perspectives. Brazilian EML history and development process were collected from legislation, minutes, reports and legal ordinances, from 2000 to 2014. The Brazilian EML and the WHO Model Lists were compared using the Anatomical Therapeutic Chemical system. Overlap between lists was verified, and linear trends were produced. Type of membership, inclusion criteria, procedures, flow and listed medicines varied greatly between the selection committees acting before and after 2012. Paradigm-changing legislation aiming at linking list compliance to public financing in 2012 produced (i) greater importance given to political and administrative stakeholders, (ii) increasing trends in number of medicines over the years, (iii) decrease in use of WHO Model List as a reference and (iv) substitution of an essential medicines list review and update process by an adoption decision output. Other issues remained unchanged. Insufficient efforts for list implementation, such as lack of physician education, presented consequences to the health system. Substantial efforts were made to produce and update the list from 2000 to 2014. However, continuous and intense health litigation disproves process outcome effectiveness.

RESUMEN

INTRODUCTION: Postoperative nausea and vomiting (PONV) affect approximately 80% of surgical patients and is associated with increased length of hospital stay and systemic costs. Preoperative and postoperative pain, anxiety and depression are also commonly reported. Recent evidence regarding their safety and effectiveness has not been synthesised. The aim of this systematic review is to evaluate the efficacy and safety of herbal medications for the treatment and prevention of anxiety, depression, pain and PONV in patients undergoing laparoscopic, obstetrical/gynaecological and cardiovascular surgical procedures. METHODS AND ANALYSIS: The following electronic databases will be searched up to 1 October 2016 without language or publication status restrictions: CENTRAL, MEDLINE, EMBASE, CINAHL, Web of Science and LILACS. Randomised clinical trials enrolling adult surgical patients undergoing laparoscopic, obstetrical/gynaecological and cardiovascular surgeries and managed with herbal medication versus a control group (placebo, no intervention or active control) prophylactically or therapeutically will be considered eligible. Outcomes of interest will include the following: anxiety, depression, pain, nausea and vomiting. A team of reviewers will complete title and abstract screening and full-text screening for identified hits independently and in duplicate. Data extraction, risk of bias assessments and evaluation of the overall quality of evidence for each relevant outcome reported will be conducted independently and in duplicate using the Grading of Recommendations Assessment Development and Evaluation classification system. Dichotomous data will be summarised as risk ratios; continuous data will be summarised as standard average differences with 95% CIs. ETHICS AND DISSEMINATION: This is one of the first efforts to systematically summarise existing evidence evaluating the use of herbal medications in laparoscopic, obstetrical/gynaecological and cardiovascular surgical patients. The findings of this review will be disseminated through peer-reviewed publications and conference presentations. SYSTEMATIC REVIEW REGISTRATION: PROSPERO CRD42016042838.

RESUMEN

The aim of this study was to identify the factors associated with the combined use of antidepressants and benzodiazepines (BDZs) in patients with major depression. We conducted a case-control study in the public health service of the city of São Paulo, Brazil. The participants were all patients being treated with antidepressants, who were diagnosed with major depression. Patients who received a combination of antidepressants and BDZs were classified as cases, and those who used only antidepressants, as controls. Data were obtained from a pharmacy database, medical records and interviews with the healthcare team. The association of predisposing factors for combined therapy was analysed using logistic regression analysis, and the odds ratios (ORs) and 95% confidence intervals (CIs) were calculated. Of the 1355 users of antidepressants, 265 had major depression, of whom 138 were cases and 127 were controls. The factors associated with combined use were age older than 35 years (OR 2.2, 95% CI 1.0-4.7), absence of comorbidities (OR 2.3, 95% CI 1.4-4.1) and no use of other drugs (OR 1.9, 95% CI 1.1-3.3). Patients with combined use were more likely to exhibit inadequate prescribing, including inappropriate antidepressants (OR 4.7, 95% CI 2.2-9.9), inadequate dosages (OR 3.62, 95% CI 1.4-9.6) and/or a non-recommended duration (OR 66.6, 95% CI 18.4-240.7). The factors identified showed the groups most susceptible to combined use in this population, who in turn are more likely to receive inappropriate prescriptions.

RESUMEN

ABSTRACT OBJECTIVE: Data on clinical practice in pediatrics on the use of analgesic, antipyretic, and nonsteroidal anti-inflammatory drugs considering the best available evidence and regulatory-agency approved use are uncertain. This study aimed to determine the frequency of prescription of these drugs according to the best scientific evidence and use approved by regulatory agencies. METHODS: This was a cross-sectional study of 150 pediatric prescriptions containing analgesic, antipyretic, and nonsteroidal anti-inflammatory drugs, followed by interview with caregivers at 18 locations (nine private drugstores and nine Basic Health Units of the Brazilian Unified Health System). The assessed outcomes included recommended use or use with no contraindication, indications with benefit evidence, and health surveillance agency-approved use. Data were analyzed in electronic databases and the variables were summarized by simple frequency. RESULTS: A total of 164 analgesic, antipyretic, and nonsteroidal anti-inflammatory drugs were prescribed to 150 children aged 1-4 years (38.6%). Dipyrone was included in 82 (54.6%) and ibuprofen in 40 (26.6%) prescriptions. Non-recommended uses were identified in 15% of prescriptions and contraindicated uses were observed in 13.3%. Nimesulide (1.5%) is still prescribed to children younger than 12 years. The dose was incorrect in 74.3% of prescriptions containing dipyrone. Of the 211 reported clinical indications, 56 (26.5%) had no evidence of benefit according to the best available scientific evidence and 66 (31.3%) had indications not approved by the regulatory agencies. CONCLUSION: There are significant discrepancies between clinical practice and recommended use of analgesic, antipyretic, and nonsteroidal anti-inflammatory drugs in pediatrics.

RESUMO OBJETIVO: Dados sobre a prática clínica em pediatria no uso de analgésicos, antipiréticos e anti-inflamatórios não esteroides considerando a melhor evidência disponível e o uso aprovado por agências reguladoras são incertos. Este estudo tem como objetivo verificar a frequência de prescrição de tais medicamentos segundo a melhor evidência científica e o uso aprovado por agências reguladoras. MÉTODO: Estudo transversal de 150 prescrições pediátricas, contendo analgésicos, antipiréticos e anti-inflamatórios não esteroides, seguido de entrevista aos cuidadores, em 18 locais (nove drogarias privadas e nove unidades de saúde do SUS). Os desfechos avaliados incluíram uso recomendado ou sem contraindicação, indicações com evidência de benefício e o uso autorizado por agências de vigilância sanitária. Os dados foram analisados em banco eletrônico e as variáveis sumarizadas por frequência simples. RESULTADOS: Foram prescritos 164 analgésicos, antipiréticos e anti-inflamatórios não esteroides para as 150 crianças entre um e quatro anos (38,6%). Dipirona constou em 82 (54,6%) e ibuprofeno em 40 (26,6%). Usos não recomendados foram encontrados em 15% das receitas e usos contraindicados em 13,3%. Nimesulida (1,5%) ainda é usada em crianças com menos de 12 anos. Em 74,3% das prescrições contendo dipirona a dose estava incorreta. Das 211 indicações clínicas referidas, 56 (26,5%) não tinham evidências de benefício segundo a melhor prova científica disponível e 66 (31,3%) eram indicações não aprovadas em agências de vigilância sanitária. CONCLUSÃO: Existem importantes discrepâncias entre prática clínica e recomendações de uso de analgésicos, antipiréticos e anti-inflamatórios não esteroides em pediatria.

RESUMEN

INTRODUCTION: Respiratory illness, often associated with cough and sputum, is frequent. In Brazil, herbal medicines are often recommended as a first-line treatment for respiratory illness. There exists uncertainty regarding the effectiveness of these treatments. No systematic review has evaluated Brazilian medicinal plants (BMP) to treat upper respiratory tract and bronchial illness (URTI). METHODS AND ANALYSIS: We will conduct a systematic review and, if appropriate, a series of meta-analyses evaluating the safety and effectiveness of BMP for URTI. Eligible randomised controlled trials and observational studies will enrol adult or paediatric patients presenting with URTI treated by BMP approved by the Brazilian Health Surveillance Agency compared with placebo, no treatment or an alternative therapy. Our search will include the Cochrane Central Register of Controlled Trials (CENTRAL), which contains the Cochrane Acute Respiratory Illness Group's Specialized Register; MEDLINE; EMBASE; CINAHL (Cumulative Index to Nursing and Allied Health Literature); Web of Science; AMED; LILACS; CAB abstracts; clinical trial.gov; the WHO Trial Register and the Brazilian thesis database (CAPES) without any language restrictions. Outcomes of interest are time to resolution of clinical symptoms and/or signs (cough, sputum production or activity limitations), severity of symptoms prior to resolution and major/minor adverse events. Teams of reviewers will, independently and in duplicate, screen titles and abstracts and the complete full text to determine eligibility. For eligible studies, reviewers will perform data abstraction and assess risk of bias of eligible trials. When appropriate, we will conduct meta-analyses. We will also assess the quality of body of evidence (confidence in estimates of effect) for each of the outcomes using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach. ETHICS AND DISSEMINATION: The systematic review will be published in a peer-reviewed journal. Brief reports of review findings will be disseminated directly to appropriate audiences via email and other modes of communication. The review will guide healthcare practice and policy in Brazil. TRIAL REGISTRATION NUMBER: Prospero CRD42014007057.

RESUMEN

Cycloeucalenone (1) and 24-oxo-31-norcycloartanone (2) obtained from Solanum cernuum Vell. were assayed to explore their pharmacologic roles. Previous studies showed that (2) has selective activity against lung tumor cell line (NCIH460) which expresses high levels of COX-2, suggesting its role in inflammatory process, and also a link between chronic inflammation and cancer-associated process. Dichloromethane crude extract (DCE) significantly reduced writhing and stretching induced by 0.8 % acetic acid at a dose of 100, 300, and 600 mg/kg, po; oral administration of different doses of (1) and (2) also displayed significant analgesic and anti-inflammatory effects in the writhing acetic acid test (p < 0.0001). Selected oral doses of both compounds (100 and 50 mg/kg) were assayed in the carrageenan-induced paw edema model. Compound (2) showed significant activity during the early phase (1.5-6 h) and also in the late phase (48 h) (p < 0.01). The anti-nociceptive activity observed for the compounds (1) and (2) and DCE was found to be related to the inhibition of different mediators involved in inflammation and nociceptive process. Both compounds decrease COX-2 protein expression, although only compound (2) reached a significant response (p < 0.05 vs control). However, in vitro Sirtuin 1 activity and TNF-α production in THP-1 macrophages were not affected.

RESUMEN

Uma transfusão de sangue com o tipo ABO incorreto pode resultar na morte dopaciente, com reação hemolítica intravascular, seguida de alterações imunológicas e bioquímicas. Considerando a pequena quantidade de estudos sobre as hemolisinas anti-A e anti-B e a importância desses anticorpos na prática transfusional, o objetivodeste trabalho foi verificar a frequência dessas hemolisinas e a associação a fatores como etnia e gênero em doadores de sangue dos bancos de sangue dos municípios de Itapeva e de Ourinhos, no interior do estado de São Paulo. Foram analisadas todas asamostras de doadores tipo O cadastradas nos bancos de sangue, com elevado nível plasmático de hemolisinas (doadores considerados perigosos). Coletaram-se os dados relativos à frequência das hemolisinas, etnia, gênero e procedência destes doadores.A frequência de doadores de sangue do grupo sanguíneo O perigosos é de 1,2%em Itapeva e de 5,3% em Ourinhos. Na cidade de Ourinhos, o risco de um doadorbranco ter hemolisina positiva é 2,16 vezes maior do que para outros doadores, e na cidade de Itapeva notou-se que o risco é menor para brancos do que para outros doadores. Em relação ao gênero, em Ourinhos o risco de um doador ter hemolisina positiva é 1,82 vezes maior para o gênero masculino, e na cidade de Itapeva, o risco foi maior para doadores do gênero feminino. A relação entre o gênero, a etnia e a frequência de hemolisinas foi diferente nas duas cidades. Mesmo assim, destaca-se a importância dos bancos de sangue estarem atentos às características de prevalência deste tipo de doador.

Blood transfusion using unmatched ABO blood types can result in patient death due to intravascular hemolytic reactions followed by immunological and biochemical changes. Considering the small number of studies on anti-A and anti-B hemolysins and the relevanceof these antibodies in the transfusional practice, this work aimed at assessing the frequency of these hemolysins and their relationship to factors such as ethnic background and gender in blood donors of blood banks located in Itapeva and Ourinhos, São Paulo State, Brazil. All samples from type O donors recorded in these two blood banks with high serum levels of hemolysins (donations considered high-risk) were analyzed. Data related to hemolysin frequencies, ethnicity, gender and origin of blood donors were collected. Thefrequency of donors belonging to the high-risk O blood group was 1.2% in Itapeva and 5.3% in Ourinhos. In Ourinhos the risk of a Caucasian donor being positive for hemolysin is 2.16 times higher than other ethnic groups and in Itapeva, it was observed that therisk is lower for Caucasians than other ethnic groups. Regarding the gender, in Ourinhos the risk of a donor being positive to hemolysin is 1.82 times greater in men and in Itapeva the risk ishigher in women. The ratios of gender and ethnic background in respect to frequency were different between the two regions. Thus it is important for blood banks to be aware of regional variations.

RESUMEN

Triterpenoids with 31-norcycloartanone structure were isolated for the first time from the Solanum genus. Cycloeucalenone and 24-oxo-31-norcycloartanone were the main constituents of the dichloromethane extract of Solanum cernuum Vell. leaves [7% (w/w) and 1.47% (w/w)]. Both triterpenoids were tested against human tumour cell lines, and 24-oxo-31-norcycloartanone was significantly active and selective against the lung tumour cell line NCI-H460 with total growth inhibition at 1.10 microg/mL, growth inhibition 50 at 0.19 microg/mL and lethal concentration 50 at 8.43 microg/mL, while cycloeucalenone showed poor activity. A homologous series of alkanes (C25-C34), beta-sitosterol, and the xanthophyll lutein were also identified. The antiulcer activity was assayed for the dichloromethane extract. In the gastric ulcer model induced by 95% ethanol, administration of 500, 1000 and 2000 mg/kg/po dichloromethane extract gave ulcer lesion indices of, respectively, 38.2, 61.0 and 81.9%, while carbenoxolone inhibited 88.9% at 200 mg/kg. In the gastric ulcer model induced by indomethacin the dichloromethane extract showed a small percentage of lesion inhibition. The ethanol extract was also analyzed and was mainly composed of glycoalkaloids, peptides and disaccharides.

RESUMEN

No Brasil o PBM (Pharmacy Benefits Management) é de utilização relativamente nova, podendo-se classificá-lo como um sistema de gerenciamento de saúde que administra benefícios na compra e venda de medicamentos. Considerando que o surgimento de bactérias resistentes está relacionado à prescrição inapropriada de antibióticos ou ao uso de antibióticos de baixa atividade, este estudo avaliou se o sistema PBM pode fornecer informações úteis sobre os perfis de prescrição e aquisição de antibióticos de efeitos sistêmicos, a partir da base de dados de uma empresa de PBM brasileira, referente a um grupo formado por 6 525 metalúrgicos de uma empresa da região de Campinas, SP, e seus dependentes, cobrindo o período de janeiro a abril de 2005. Observou-se que 7,7 por cento de todos os medicamentos adquiridos eram antibióticos sistêmicos, numa média 2,4 antibióticos e ao custo de R$ 51,80 por receita. A amoxicilina foi o fármaco mais prescrito e em 92,7 por cento dos casos o usuário adquiriu o medicamento até um dia após a consulta médica. A partir das listas das especialidades farmacêuticas adquiridas (por unidade de venda), dos laboratórios fabricantes, dos antibióticos que compunham cada produto, das datas de emissão das receitas e da dispensação, foi possível concluir que o sistema permite extrair informações relevantes sobre o tema enfocado.

Pharmacy Benefits Management (PBM), a system that manages benefits in the purchase and sale of drugs, is of relatively recent implementation in Brazil. Taking into account that the development of bacterial resistance is related to the inadequate prescription of antibiotics or to the use of low activity antibiotics, this study sought to assess the capability of PBM to provide useful information on the profiles of prescription and purchase of systemic antibiotics. The data used for this purpose were collected from the database of a Brazilian PBM company and related to a group of 6 525 metalworkers of a company located in the region of Campinas, SP, and to their dependents, covering the period from January to April 2005. Of the drugs purchased, 7.7 percent were systemic antibiotics, with a mean of 2.4 antibiotics and a mean cost of R$ 51.80 per prescription. Amoxicillin was the most prescribed drug. In 92.7 percent of cases, users purchased the prescribed drug within one day of the medical visit. Based on the lists of purchased pharmaceutical specialties (per retail package), manufacturers, antibiotics present in the composition of each product, prescription dates, and dispensation dates, the system was found capable of providing relevant information on the theme investigated.
