Levantamento dos trabalhos científicos de farmacoeconomia realizados no Brasil por farmacêuticos
Trabalho de Conclusão de Curso (graduação)—Universidade de Brasília, Faculdade de Ceilândia, Curso de Farmácia, 2015.A farmacoeconomia foi definida como sendo a descrição e a análise dos custos da terapia farmacêutica para os sistemas de assistência à saúde e para a sociedade, apresentando-se como um valioso instrumento de apoio para a tomada de decisão racional e de informação no cenário de saúde global permitindo a comparação dos custos e dos resultados dos diversos tratamentos para os pacientes. Sendo assim, esse trabalho tem como objetivo realizar o levantamento de estudos farmacoeconômicos desenvolvidos por farmacêuticos brasileiros entre 2003 e 2014. Foi realizada uma revisão da literatura adotando como descritores farmacoeconomia, análise de custo, análise custo efetividade, análises custo benefício, análise custo utilidade, minimização de custos e economia da saúde, sem restrição de período, nas bases de dados Scielo, Medline, Bireme e Lilacs. Posteriormente realizou-se uma busca ativa. Foram identificados 329 trabalhos que, após aplicados os critérios de exclusão, selecionou-se apenas os trabalhos publicados que continham profissionais farmacêuticos como autor ou coautor. Obteve-se um resultado com 33 trabalhos publicados no Brasil. A partir dos resultados, foi observado um aumento de publicações a partir do ano de 2011. De maneira geral, o conceito adotado nesses trabalhos se referia a aplicação das ferramentas da farmacoeconomia para o estudo comparativo de medicamentos. A farmacoeconomia no Brasil é uma prática crescente demonstrando o interesse dos farmacêuticos e de outros profissionais da saúde em promover um melhor tratamento terapêutico ao paciente e a otimizar os recursos financeiros. Entretanto, ainda é pequeno o número de estudos realizados no país.The Pharmacoeconomics was defined as the description and analysis of the cost of pharmaceutical therapy for healthcare systems and society. It is a valuable instrument of support for rational decision-making and information on the global health scene allowing the comparison of the costs and the results of various treatments. Therefore, this study aims to carry out the survey of pharmacoeconomics studies developed by Brazilian pharmaceutical between 2003 and 2014. The literature was reviewed adopting as descriptors: Pharmacoeconomics, cost analysis, cost effectiveness analysis, cost benefit analysis, cost-utility analysis, minimizing costs and health economics. The active search was made on Medline, Scielo, Bireme and Lilacs. There was no restriction of date articles on searching and were analyzed articles in English and Portuguese. As a result, 329 articles were identified, however after applied the exclusion criteria only 33 articles published in Brazil were selected, since only those were published by pharmaceutical professionals. The result of the study showed an increase in publications from the year 2011. In General, the concept adopted in these works, meant the application of Pharmacoeconomics tools for the comparative study of medicines. The Pharmacoeconomics in Brazil is a growing practice demonstrating the interest of pharmacists and other health professionals in promoting a better therapeutic treatment to the patient and optimizing financial resources. However, the number of studies carried out in the country is still small
Cost-utility analysis of opportunistic and systematic diabetic retinopathy screening strategies from the perspective of the Brazilian Public Healthcare System
Objective: To perform a cost-utility analysis of diabetic retinopathy (DR) screening strategies from the perspective of the Brazilian Public Healthcare System. Methods: A model-based economic evaluation was performed to estimate the incremental costs per quality-adjusted life-year (QALY) gained between three DR screening strategies: (1) the opportunistic ophthalmology referral-based (usual practice), (2) the systematic ophthalmology referral-based, and (3) the systematic teleophthalmology-based. The target population included individuals with type 2 diabetes (T2D) aged 40 years, without retinopathy, followed over a 40-year time horizon. A Markov model was developed with five health states and a 1-year cycle. Model parameters were based on literature and country databases. One-way and probabilistic sensitivity analyses were performed to assess model parameters’ uncertainty. WHO willingness-to-pay (WHO-WTP) thresholds were used as reference (i.e. one and three times the Brazilian per capita Gross Domestic Product of R21445/QALY gained (4) and less effective (incremental QALY = −0.012) compared to the systematic teleophthalmology-based screening. The probability of systematic teleophthalmology-based screening being cost-effective compared to usual practice was 0.46 and 0.67 at the minimum and the maximum WHO-WTP thresholds, respectively. Conclusion: Systematic teleophthalmology-based DR screening for the Brazilian population with T2D would be considered very cost effective compared to the opportunistic ophthalmology referral-based screening according to the WHO-WTP threshold. However, there is still a considerable amount of uncertainty around the results
Expanding the knowledge about Leishmania species in wild mammals and dogs in the Brazilian savannah
Background: Wild, synanthropic and domestic mammals act as hosts and/or reservoirs of several Leishmania spp. Studies on possible reservoirs of Leishmania in different areas are fundamental to understand host-parasite interactions and develop strategies for the surveillance and control of leishmaniasis. In the present study, we evaluated the Leishmania spp. occurrence in mammals in two conservation units and their surroundings in Brasília, Federal District (FD), Brazil. Methods: Small mammals were captured in Brasília National Park (BNP) and Contagem Biological Reserve (CBR) and
dogs were sampled in residential areas in their vicinity. Skin and blood samples were evaluated by PCR using different molecular markers (D7 24Sα rRNA and rDNA ITS1). Leishmania species were identified by sequencing of PCR products. Dog blood samples were subjected to the rapid immunochromatographic test (DPP) for detection of anti-Leishmania infantum antibodies. Results: 179 wild mammals were studied and 20.1% had Leishmania DNA successfully detected in at least one sample. Six mammal species were considered infected: Clyomys laticeps, Necromys lasiurus, Nectomys rattus, Rhipidomys macrurus, Didelphis albiventris and Gracilinanus agilis. No significant difference, comparing the proportion of individuals with Leishmania spp., was observed between the sampled areas and wild mammal species. Most of the positive samples were collected from the rodent N. lasiurus, infected by L. amazonensis or L. braziliensis. Moreover, infections by Trypanosoma spp. were detected in N. lasiurus and G. agilis. All 19 dog samples were positive by DPP; however, only three (15.8%) were confirmed by PCR assays. DNA sequences of ITS1 dog amplicons showed 100% identity with L. infantum sequence. Conclusions: The results suggest the participation of six species of wild mammals in the enzootic transmission of Leishmania spp. in FD. This is the first report of L. amazonensis in N. lasiurus
The psychological science accelerator’s COVID-19 rapid-response dataset
In response to the COVID-19 pandemic, the Psychological Science Accelerator coordinated three large-scale psychological studies to examine the effects of loss-gain framing, cognitive reappraisals, and autonomy framing manipulations on behavioral intentions and affective measures. The data collected (April to October 2020) included specific measures for each experimental study, a general questionnaire examining health prevention behaviors and COVID-19 experience, geographical and cultural context characterization, and demographic information for each participant. Each participant started the study with the same general questions and then was randomized to complete either one longer experiment or two shorter experiments. Data were provided by 73,223 participants with varying completion rates. Participants completed the survey from 111 geopolitical regions in 44 unique languages/dialects. The anonymized dataset described here is provided in both raw and processed formats to facilitate re-use and further analyses. The dataset offers secondary analytic opportunities to explore coping, framing, and self-determination across a diverse, global sample obtained at the onset of the COVID-19 pandemic, which can be merged with other time-sampled or geographic data
A global experiment on motivating social distancing during the COVID-19 pandemic
Finding communication strategies that effectively motivate social distancing continues to be a global public health priority during the COVID-19 pandemic. This cross-country, preregistered experiment (n = 25,718 from 89 countries) tested hypotheses concerning generalizable positive and negative outcomes of social distancing messages that promoted personal agency and reflective choices (i.e., an autonomy-supportive message) or were restrictive and shaming (i.e., a controlling message) compared with no message at all. Results partially supported experimental hypotheses in that the controlling message increased controlled motivation (a poorly internalized form of motivation relying on shame, guilt, and fear of social consequences) relative to no message. On the other hand, the autonomy-supportive message lowered feelings of defiance compared with the controlling message, but the controlling message did not differ from receiving no message at all. Unexpectedly, messages did not influence autonomous motivation (a highly internalized form of motivation relying on one’s core values) or behavioral intentions. Results supported hypothesized associations between people’s existing autonomous and controlled motivations and self-reported behavioral intentions to engage in social distancing. Controlled motivation was associated with more defiance and less long-term behavioral intention to engage in social distancing, whereas autonomous motivation was associated with less defiance and more short- and long-term intentions to social distance. Overall, this work highlights the potential harm of using shaming and pressuring language in public health communication, with implications for the current and future global health challenges
Search for dark matter produced in association with bottom or top quarks in √s = 13 TeV pp collisions with the ATLAS detector
A search for weakly interacting massive particle dark matter produced in association with bottom or top quarks is presented. Final states containing third-generation quarks and miss- ing transverse momentum are considered. The analysis uses 36.1 fb−1 of proton–proton collision data recorded by the ATLAS experiment at √s = 13 TeV in 2015 and 2016. No significant excess of events above the estimated backgrounds is observed. The results are in- terpreted in the framework of simplified models of spin-0 dark-matter mediators. For colour- neutral spin-0 mediators produced in association with top quarks and decaying into a pair of dark-matter particles, mediator masses below 50 GeV are excluded assuming a dark-matter candidate mass of 1 GeV and unitary couplings. For scalar and pseudoscalar mediators produced in association with bottom quarks, the search sets limits on the production cross- section of 300 times the predicted rate for mediators with masses between 10 and 50 GeV and assuming a dark-matter mass of 1 GeV and unitary coupling. Constraints on colour- charged scalar simplified models are also presented. Assuming a dark-matter particle mass of 35 GeV, mediator particles with mass below 1.1 TeV are excluded for couplings yielding a dark-matter relic density consistent with measurements

A multi-country test of brief reappraisal interventions on emotions during the COVID-19 pandemic.
The COVID-19 pandemic has increased negative emotions and decreased positive emotions globally. Left unchecked, these emotional changes might have a wide array of adverse impacts. To reduce negative emotions and increase positive emotions, we tested the effectiveness of reappraisal, an emotion-regulation strategy that modifies how one thinks about a situation. Participants from 87 countries and regions (n = 21,644) were randomly assigned to one of two brief reappraisal interventions (reconstrual or repurposing) or one of two control conditions (active or passive). Results revealed that both reappraisal interventions (vesus both control conditions) consistently reduced negative emotions and increased positive emotions across different measures. Reconstrual and repurposing interventions had similar effects. Importantly, planned exploratory analyses indicated that reappraisal interventions did not reduce intentions to practice preventive health behaviours. The findings demonstrate the viability of creating scalable, low-cost interventions for use around the world
