A grande iniquidade socioeconômica que prevalece no Brasil e a existência de um sistema nacional de saúde com cobertura universal torna necessário o acompanhamento da evolução e das iniquidades sociais no acesso aos serviços. Analisar as mudanças na prevalência do uso de serviços de saúde e o grau de iniquidade social considerando a demanda, o uso e acesso, resolução de problemas de saúde, satisfação e utilização dos serviços de saúde do Sistema Único de Saúde (SUS), segundo o nível de escolaridade, na população residente na zona urbana do Município de São Paulo, em 2003 e 2015. Foram analisados dados de dois inquéritos domiciliares de saúde de base populacional (Inquérito de Saúde do Município de São Paulo - ISA-Capital) de 2003 e 2015. As variáveis dependentes relacionadas à utilização de serviços de saúde nas duas semanas anteriores à pesquisa e devido à presença de alguma doença incluem: demanda, acesso, satisfação, resolução do problema e a natureza pública ou privada do serviço. A prevalência foi estimada por meio da escolaridade e das razões de prevalência (RP) por regressão de Poisson. Entre 2003 e 2015, a demanda por cuidados de saúde, acesso, resolutividade e utilização de serviços públicos de saúde aumentou. As iniquidades no uso da saúde pública mudaram de 2003 para 2015 quando se trata do nível de escolaridade. Não foram encontradas iniquidades sociais na utilização dos serviços de saúde no Município de São Paulo em termos de demanda, acesso, satisfação e resolutividade, segundo o nível de escolaridade. Os resultados mostram avanços na utilização e resolutividade dos serviços de saúde, bem como uma forte concentração do uso do SUS pela população com menor nível de escolaridade. Os resultados indicam os avanços do SUS, mas também mostram que ainda há desafios no uso e acesso aos serviços.

The great socioeconomic inequality that prevails in Brazil and the existence of a national health system with universal coverage places the need to monitor the evolution and social inequities regarding access to these services. This study aims to analyze the changes in the prevalence of health care use and the extent of social inequality in the demand, use and, access, resolution of health problems, satisfaction, and health care use of Brazilian Unified National Health System (SUS) according to education levels in the population living in the urban area of the Municipality of São Paulo, in 2003 and 2015. We analyzed data from two population-based household health surveys (Health Survey in São Paulo City - ISA-Capital) from 2003 and 2015. Dependent variables related to health care use in the two weeks preceding the survey and due to diseases included demand, access, satisfaction, problem resolution, and the public or private nature of the service. Prevalence was estimated using level of education and prevalence ratios (PR) by the Poisson regression. In the period, the demand for health care, access, resolution, and use of public health care increased from 2003 to 2015. Inequities in public health care use changed from 2003 to 2015 according to level of education. We found no social inequities in health care use in the municipality of São Paulo regarding demand, access, satisfaction, and resolution according to levels of education. Results show progress in the use and resolution of health care services, as well as the strong concentration of the use of SUS by the population with lower education. Results indicate the progress that SUS has made, but also show persistent challenges in the use and access to services.

Abstract This work developed biscuits with the partial substitution of wheat flour with olive pomace flour (OPF). The wheat flour contents substituted by OPF in the biscuits were 0%, 10%, and 20%. The effects of the flour on the chemical composition, lipid profile, and sensory aspects of the reformulated biscuits were evaluated. The data showed that the OPF has a high concentration of dietary fiber (43.75%) and 27.70% lipids. The biscuit with 10% of the wheat flour replaced by OPF has 4.29% of total dietary fiber and 22.61% of lipids, whereas the biscuits made by substituting 20% of the wheat flour with OPF have 8.52% of total dietary fiber and 23.78% of lipids. The incorporation of OPF increased the contents of lipids, minerals, and dietary fiber. Sensorially, the sensory descriptors were not beneficial to characterize the biscuits reformulated with OPF. Also, the lightness, texture, and brittleness decreased in the biscuits with added OPF, as did the loss from baking. Hence, the BIS10 biscuit proved to have the potential to be better explored from the physicochemical and sensory viewpoint.

Abstract Objective: This study monitors trends in access to cancer screening, focusing on mammography, Papanicolaou (Pap smear), and Prostate-Specific Antigen (PSA), assessing the magnitude of inequality in the city of São Paulo from 2003 to 2015 according to education level. Method: This is a cross-sectional population-based study conducted with data from the 2003, 2008, and 2015 editions of the Health Survey of the City of São Paulo (ISA-Capital). Outcome variables were the proportion of mammography, Papanicolaou (Pap smear), and Prostate-Specific Antigen (PSA) tests according to the protocols. Inequality was measured by education level according to years of study. For static analysis, Poisson regression was used to estimate proportion ratios. Results: The proportion of Pap smears remained stationary at a high level (>89%) throughout the study period, while access to mammography and PSA tests significantly increased in the 2003–2015 period. The present results indicate inequalities in access to cancer screening due to education, and being more expressive for mammography and PSA tests. However, this inequality significantly decreased over the period analyzed comparing the most educated individuals with those with the lowest educational level. In addition, an increase in the proportion of tests performed in the Brazilian Unified Health System was identified, especially for mammography and PSA tests, in the period 2003–2015. Conclusions: The inequalities observed in the access to preventive exams were influenced by the level of education. The offer of exams was expanded, more significantly for mammography and PSA, especially among the less educated group.

ABSTRACT Objective To understand the feasibility of FGFR3 tests in the Brazilian public health context, and to sample the mutational burden of this receptor in high-grade muscle invasive bladder cancer. Methods A total of 31 patients with high-grade muscle-invasive bladder cancer were included in the present study. Either transurethral resection of bladder tumor or radical cystectomy specimens were analyzed. Formalin-fixed paraffin-embedded tissue blocks were sectioned, hematoxylin and eosin stained, and histologic sections were reviewed. Total RNA was extracted using the RNeasy DSP formalin-fixed paraffin-embedded kit. Qualitative results were displayed in Rotor-Gene AssayManager software. Results Six patients were excluded. From the samples analyzed, four (16.7%) were considered inadequate and could not have their RNA extracted. Two patients presented FGFR3 mutations, accounting for 9.5% of material available for adequate analysis. The two mutations detected included a Y373C mutation in a male patient and a S249C mutation in a female patient. Conclusion FGFR3 mutations could be analyzed in 84% of our cohort and occurred in 9.5% of patients with high-grade muscle invasive bladder cancer in this Brazilian population. FGFR3 gene mutations are targets for therapeutic drugs in muscle-invasive bladder cancer. For this reason, know the frequency of these mutations can have a significant impact on public health policies and costs provisioning.

ABSTRACT Objective To evaluate Primary Health Care attributes and analyze the association between the fulfilment of these attributes and problem-solving capacity of services for elderly patients. Methods A cross-sectional, observational, quantitative study. The Primary Care Assessment Tool, designed to assess Primary Health Care attributes, was employed to evaluate elderly users of Primary Care Units located in the south region of the city of São Paulo (SP). Results Many attributes assessed at the reference services were considered as unsatisfactory by users. Overall scores were also below the cut-off point. “First contact access – use”, “longitudinality” and “coordination – information system” were the only attributes considered as satisfactory. Also, more than half (62.7%) of respondent patients reported having been referred to specialized services. A combined analysis of these three outcomes revealed users referred to other services had a significantly better perception of Primary Health Care attributes. Conclusion The study provides important insights on satisfaction of elderly individuals and the problem-solving capacity of health care services, especially for the study population. Findings reported emphasize the association between Primary Health Care attributes and the problem-solving capacity of health care services at this level.

ABSTRACT Objective: To analyze the factors associated with the SARS-CoV-2 infection among oral health professionals. Material and Methods: This was a cross-sectional study in the city of São Paulo, São Paulo State, Brazil. Professionals from three different categories were included: dental surgeons (DS), dental assistants (DA), and dental hygienists (DH). A questionnaire was created on a digital platform and sent via institutional email to each subject. The questionnaire contained 32 questions about sociodemographic, work, and behavior factors. The data about SARS-CoV-2 infection was confirmed through RT-PCR exams. Descriptive (absolute and relative frequencies) and inferential analyses (chi-squared or Fisher’s exact test) (p<0.05) were performed. Results: There was a SARS-CoV-2 infection prevalence of 3.8% for DS, 30.0% for DH, and 33.3% for DA. SARS-CoV-2 was associated with a lower income (p=0.027), a lower education level (p=0.011), the category of technical professionals (DA and DH) (p=0.025), and using public transportation to commute to work (p=0.009). Conclusion: Sociodemographic factors like lower income and education levels and work factors like job category and public transportation were associated with COVID-19 among professionals on the oral health teams.

OBJECTIVES: To analyze the use and acquisition of medicines in São Paulo, Brazil, in 2003 and 2015, according to sociodemographic factors, socioeconomic status, and health conditions of the population. METHODS: Data were obtained from population health surveys “ISA-Capital”. Descriptive analysis, bivariate analysis, and logistic regression models were used to evaluate the use of medicines and coverage by the Brazilian Unified Health System (SUS) according to socioeconomic status and health conditions in two periods: 2003 and 2015. RESULTS: From 2003 to 2015, the surveys showed an increase in the income and education level of the study population. There was no increase in the prevalence of chronic diseases and use of medicines from 2003 to 2015. The provision of medicines by SUS was higher in 2015 than in 2003, and the coverage by SUS was higher in the population with lower education level and income in both 2003 and 2015. CONCLUSIONS: The use of medicines, mainly for chronic disease control, did not change over the years, and there was an increase in SUS coverage for medicines during 2003-2015 in all population groups, with a greater impact on the lower socioeconomic status population. The programs of the provision of medicines implanted since 2003 had influenced the greater SUS coverage for medicines and in the reduction of inequalities in access to medicines.

ABSTRACT Introduction: Low levels of daily physical activity is considered to be one of the causes of the exorbitant increase in overweight and obese children, and associated comorbidities. Therefore, it is vital to develop strategies that will be implemented consistently, to improve this situation. Studies have used dance as a resource for training overweight and obese children, but the lack of information about the creation process and its respective stages reduce the possibility of these proposals being effectively applied. Objectives: To describe the steps in the creation of a dance protocol as a training resource, and its effectiveness in improving the health parameters of overweight and obese children. Methods: 30 children (9 ± 1.1 years) underwent training sessions consisting of a five-minute warm-up at 60% HRmax., and four 10-minute sessions at 70% to 80% at HRmax. interspersed with five 2-minute active recovery periods at 60% HRmax. The sessions were carried out three times a week, and lasted 60 minutes each, over a 13-week period. Before and after the training, the body composition, body mass index (BMI), BMI z-score, waist circumference (WC), waist-to-height ratio (WHtR), systolic (SBP) and diastolic (DBP) blood pressure and blood variables were measured. Statistical analysis was performed using a mixed effects regression model. Results: After training with Afro-Brazilian dance, there was a significant reduction (p<0.05) in the BMI z-score and waist-to-height ratio. Conclusion: Afro-Brazilian dance training was a strategy with a positive effect on BMI z-score and waist-to-height ratio in overweight and obese children. Level of evidence IV; Case series.

Quantum dots (QDs) are semiconductor nanocrystals, which present unique photophysical properties, enabling their application as new fluorescent platforms for biomedical sciences. Colloidal QDs are end-capped with organic or inorganic compounds, not only to prevent their agglomeration but also to provide reaction sites for the attachment of targeting (bio)molecules, nanoparticles or other interfaces, for specific biological purposes. The (bio)conjugation can involve non-covalent or covalent interactions, which can be accomplished through different strategies. The final assembly needs to maintain its chemical and optical stability and biochemical functionality. Although a relative good comprehension of the experimental procedures has been established, the bioconjugation process is still a challenge. The present manuscript aims to review the main (bio)conjugation strategies successfully applied to QDs, describing the steps necessary to prepare stable targeting fluorescent nanoplatforms, as well as some usual methods used to evaluate and optimize this process.

RESUMO INTRODUÇÃO: Interação medicamentosa é uma importante causa de morbidade mundial. Apresenta especial importância em pacientes oncológicos, pois esses frequentemente estão em uso de polifarmácia, podendo haver interações entre os medicamentos e os quimioterápicos utilizados. OBJETIVO: Avaliar a interação medicamentosa entre a quimioterapia e outros medicamentos em pacientes oncológicos. MÉTODOS: Estudo transversal realizado em serviço ambulatorial de oncologia de um hospital público terciário. Foram incluídos 235 pacientes, identificando-se quais medicamentos eram utilizados por eles. Por meio do auxílio do banco de dados do MedScape e Epocrates, avaliaram-se as interações entre as medicações e os quimioterápicos, definindo sua frequência e dividindo sua gravidade da interação em leve, monitorização próxima e grave. RESULTADOS: Do total estudado, 161 pacientes apresentavam alguma interação medicamentosa, sendo nove tipos de interações leves, 23 tipos de interações com necessidade de monitorização próxima e dois tipos de interações graves. As interações mais frequentes foram entre fluoracil e leucovorin (32 casos) e ciclofosfamida e doxorrubicina (19 casos). As interações sérias foram entre aspirina e pemetrexed; e leucovorim e bactrim. CONCLUSÃO: No presente trabalho, interações medicamentosas foram frequentes, incluindo interações graves com potencial aumento de morbimortalidade. Assim, faz-se necessário que oncologistas tracem um plano terapêutico levando em consideração as possíveis interações medicamentosas entre a quimioterapia prescrita e demais medicações em uso pelos pacientes.

SUMMARY INTRODUCTION: Drug interaction is an important cause of global morbidity. It is of particular importance in cancer patients since they are often in use of polypharmacy, related to interactions between the drugs and the chemotherapeutics used. OBJECTIVE: To evaluate the drug interaction between chemotherapy and other drugs in cancer patients. METHODS: a cross-sectional study carried out in the outpatient oncology department of a public tertiary hospital. Two hundred thirty-five patients were included, and the drugs they were using were identified. Using the MedScape and Epocrates database, we evaluated the interactions between medications and chemotherapy by defining their frequency and dividing their severity from interaction into mild, close monitoring necessity and severe. RESULTS: 161 patients had some drug interaction. We identified 9 types of mild interactions, 23 types of interactions with close monitoring necessity, and 2 types of serious interactions. The most frequent interactions were between fluorouracil and leucovorin (32 cases) and cyclophosphamide and doxorubicin (19 cases). Serious interactions were between aspirin and pemetrexed; and leucovorin and Bactrim. CONCLUSION: In the present study, drug interactions were frequent, including serious interactions with a potential increase in morbidity and mortality. Thus, it is necessary for oncologists to draw up a therapeutic plan considering potential interactions between prescribed chemotherapy and current medications in use by patients.
