RESUMEN

Long-term memory (LTM) formation is dependent on neurochemical changes that guarantee that a recently formed memory (short-term memory [STM]) remains in the specific neural circuitry via the consolidation process. The persistence of recognition memory has been evidenced by using behavioral tagging in young adult rats, but it has not been effective on aging. Here, we investigated the effects of treatment with a standardized extract of Ginkgo biloba (EGb) associated with novelty on the consolidation of object location memory (OLM) and its persistence after weak training of spatial object preference in young adult and aged rats. The object location task used in this study included two habituation sessions, training sessions associated or not associated with EGb treatment and contextual novelty, and short-term or long-term retention testing sessions. Altogether, our data showed that treatment with EGb associated with novelty close to the time of encoding resulted in STM that lasted for 1 h and persisted for 24 h for both young adult and aged rats. In aged rats, the cooperative mechanisms induced robust long-term OLM. Our findings support and extend our knowledge about recognition memory in aged rats and the modulating effects of EGb treatment and contextual novelty on the persistence of memory.

RESUMEN

BACKGROUND: In Brazil, the COVID-19 pandemic found the universal and public Unified Health System (SUS) with problems accumulated over time, due, among other reasons, to low investments, and disparities in resource distribution. The preparedness and response of the healthcare system, involving the SUS and a private sector, was affected by large socioeconomic and healthcare access inequities. This work was aimed at offering an overview of COVID-19 inpatient mortality during the pandemic in Brazil, exploring factors associated with its variations and, specifically, differences across public, private (for-profit) and philanthropic (private non-profit) inpatient healthcare units, providers, and non-providers of services to the SUS. METHODS: This cross-sectional study used public secondary data. The main data source was the SIVEP-Gripe, which comprises data on severe acute respiratory illness records prospectively collected. We also employed the National Record of Health Establishments, the SUS' Hospitalization Information System and municipalities' data from IBGE. We considered adult COVID-19 hospitalizations registered in SIVEP-Gripe from February 2020 to December 2022 in inpatient healthcare units with a minimum of 100 cases in the period. Data analyses explored the occurrence of inpatient mortality, employing general linear mixed models to identify the effects of patients', health care processes', healthcare units' and municipalities' characteristics on it. RESULTS: About 70% of the COVID-19 hospitalizations in Brazil were covered by the SUS, which attended the more vulnerable population groups and had worse inpatient mortality. In general, non-SUS private and philanthropic hospitals, mostly reimbursed by healthcare insurance plans accessible for more privileged socioeconomic classes, presented the best outcomes. Southern Brazil had the best performance among the macro-regions. Black and indigenous individuals, residents of lower HDI municipalities, and those hospitalized out of their residence city presented higher odds of inpatient mortality. Moreover, adjusted inpatient mortality rates were higher in the pandemic peak moments and were significantly reduced after COVID-19 vaccination reaching a reasonable coverage, from July 2021. CONCLUSIONS: COVID-19 exposed socioeconomic and healthcare inequalities and the importance and weaknesses of SUS in Brazil. This work indicates the need to revert the disinvestment in the universal public system, a fundamental policy for reduction of inequities in the country.

RESUMEN

Objective: To identify correlations between COVID-19, demographic and socioeconomic characteristics, and the capacity of Latin American health systems to respond to health emergencies. Method: An ecological study was performed using secondary data from 20 Latin American countries regarding incidence, mortality, testing and vaccination coverage for covid-19 from 2020 to 2021 as well as demographic and socioeconomic indicators. The preparedness of countries to respond to health emergencies was explored based on the 2019 State Party Self-Assessment Annual Report on the implementation of the International Health Regulations (IHR). Statistical analyses were performed using the Spearman correlation test (rho). Results: A high positive correlation was noted between gross domestic product per capita and the human development index with the incidence of COVID-19, testing, and vaccination coverage; and between the proportion of elderly population and vaccination coverage. No correlations were identified between the covid-19 indicators and previous IHR implementation capacities. Conclusions: The lack of correlation between indicators related to COVID-19 and the ability to implement the IHR may reflect limitations of the indicators used or of the IHR monitoring tool as an instrument that induces the preparedness of countries to face health emergencies. The results suggest the importance of structural conditioning factors and the need for longitudinal, comparative, and qualitative studies to understand the factors that influenced the response of countries to COVID-19.


Objetivo: Determinar las posibles correlaciones entre la COVID-19, las características demográficas y socioeconómicas, y la capacidad de los sistemas de salud latinoamericanos para responder a emergencias de salud. Método: Se realizó un estudio ecológico con datos secundarios de 20 países latinoamericanos sobre la incidencia, la mortalidad, las pruebas y la cobertura de vacunación relativas a la COVID-19 en el período 2020-2021, y con información demográfica y socioeconómica. Se exploró la preparación de los países para responder a emergencias de salud a partir del Informe Anual de Autoevaluación de los Estados Miembros de la Organización Mundial de la Salud del 2019 sobre la implementación del Reglamento Sanitario Internacional (RSI). Los análisis estadísticos se realizaron con la prueba de correlación (ro) de Spearman. Resultados: Se observó una alta correlación positiva del producto interno bruto per cápita y del índice de desarrollo humano con la incidencia, las pruebas y la cobertura de vacunación respecto a la COVID-19, así como de la proporción de personas mayores en la población con la cobertura de vacunación. No se observó ninguna correlación entre los indicadores de COVID-19 y la capacidad previa de implementación del RSI. Conclusiones: La falta de correlación entre los indicadores relativos a la COVID-19 y la capacidad de implementación del RSI puede deberse a limitaciones de los indicadores utilizados o del mecanismo de seguimiento del RSI como instrumento inductor de la preparación de los países para enfrentar emergencias de salud. Los resultados sugieren la importancia de los factores condicionantes estructurales y la necesidad de realizar estudios longitudinales, comparativos y cualitativos para determinar los factores que influyeron en la respuesta de los países a la COVID-19.

RESUMEN

PURPOSE: The purpose of this 3D finite element analysis was to evaluate the biomechanical effects of different materials used to fabricate occlusal devices to achieve stress distribution in simulated abutment screws, dental implants, and peri-implant bone tissue in individuals who clench their teeth. MATERIALS AND METHODS: Eight 3D models simulated a posterior maxillary bone block with three external hexagon implants (Ø4.0 × 7.0 mm) supporting a 3-unit screw-retained metal-ceramic prosthesis with different crown connection (splinting), and the use of an occlusal device (OD). The OD was modeled to be 2-mm thick. ANSYS 19.2 software was used to generate the finite-element models in the pre-and post-processing phases. Simulated abutment screws and dental implants were evaluated by von Mises stress maps, and simulated bone was evaluated by maximum principal stress and microstrain maps by using a finite element software program. RESULTS: The highest stress values in the dental implants and screws were observed in single crowns without OD (M1). Furthermore, the highest stress values and bone tissue strain were found in single crowns without OD (M1). The simulated material for the OD did not cause many discrepancies in terms of the stress magnitude in the simulated dental implant and abutment screw for both single and splinted crowns; however, more rigid materials exhibited lower stress values. CONCLUSION: The use of OD was effective in reducing stress in the simulated implants and abutment screws and stress and strain in the simulated bone tissue. The material used to simulate the OD influenced the biomechanical behavior of implant-supported fixed prostheses, whereas splints with rigid materials such as PEEK and PMMA exhibited better biomechanical behavior.

RESUMEN

OBJECTIVE: To analyze the temporal evolution of the pattern of hospital use in the context of the COVID-19 pandemic in Brazil. METHODS: This retrospective observational study compared hospital use and mortality in the Brazilian Unified Health System (SUS) in the first six months of the COVID-19 pandemic with the year before the onset of the pandemic in six Brazilian capitals (São Paulo, Rio de Janeiro, Manaus, Fortaleza, Recife, and Brasilia). It was based on secondary administrative data from the SUS Hospital Information System (SIH), focusing on the number of hospitalizations per fortnight, age, and gender of patients, hospital length of stay, and the proportions of surgical, elective, with the use of ICU, and resulting in death hospitalizations. It also compared the number of hospitalizations and mortality related to frequent diagnostic groups. RESULTS: A significant drop was identified in the number of hospitalizations as of March 2020, with the first peak of COVID-19 hospitalizations in five capitals recorded in May 2020. In the six capitals, we observed significant reductions in the mean number of hospitalizations per fortnight from the beginning of the pandemic. We also identified an increase in the mean age of the patients and the proportion of male patients. The proportion of surgical and elective hospitalizations dropped significantly in all capitals, while the proportion of hospitalizations with ICU use increased significantly. Significant increases in-hospital mortality were also recorded in the six capitals with the pandemic, including or excluding COVID-19 hospitalizations from the comparison. CONCLUSION: The pandemic caused changes in the pattern of use and hospital indicators in the first six months in the cities considered, evidencing the need for attention to diseases with a hospital production altered by the COVID-19 course and health system performance problems in the face of challenges.

RESUMEN

This study evaluated the antimicrobial effect of essential oils (EO) and organic acids (OA) against Salmonella Enteritidis in chicken feed and during an in vitro model that mimics the chicken digestive process. The minimal inhibitory concentration (MIC) of allyl isothiocyanate (AITC), carvacrol (CV), propionic acid (PROP) and caproic acid (CAP) were individually determined. Then, based on the MICs of each compound, combinations of EOs and/or OAs were tested to evaluate their synergic antimicrobial effect. The synergic effect of AITC and CAP was the most efficient against the bacterial strain tested. Commercial feed was inoculated with a 5-strain cocktail of S. Enteritidis and treated with different doses of AITC + CAP to evaluate their effect on the growth/survival of the pathogen. In addition, the simulated digestion model was used to access the antimicrobial effect of AITC + CAP added to the feed towards S. Enteritidis and Lactobacillus plantarum. Synergistic effect was found between AITC (0.065 mM) and CAP (17.5 mM) against S. Enteritidis in chicken feed, where S. Enteritidis was reduced to undetectable levels (<1.00 log CFU/g). AITC (1.95 mM) + CAP (45 mM) also decreased (p < 0.05) the population of S. Enteritidis in the simulated digestion, while the growth of L. plantarum was not affected. Therefore, the addition of AITC + CAP in feed might be a potential natural antimicrobial able to prevent economic losses caused for Salmonella in chicken.

RESUMEN

BACKGROUND: Histoplasmosis is worldwide systemic mycoses caused by the dimorphic fungus Histoplasma capsulatum. The isolation and identification of H. capsulatum in culture is the reference test for histoplasmosis diagnosis confirmation. However, in the absence of it, serology has been used as a presumptive diagnosis through antibody and antigen detection. The purpose of the present study was to validate an immunoassay method (western blot) for antibodies detection in the diagnosis of histoplasmosis. METHODS: To validate the western blot (WB) a study was conducted using 118 serum samples from patients with histoplasmosis and 118 serum controls collected from January 2000 to December 2013 in residents of the Rio de Janeiro State, Brazil. Diagnostic validation parameters were calculated based on the categorization of results obtained in a 2 × 2 table and subjected to statistical analysis. In addition, the viability of deglycosylated histoplasmin antigen (ptHMIN) onto nitrocellulose membranes previously sensitized was evaluated during the same period. RESULTS: The WB test showed sensitivity of 94.9 %, specificity of 94.1 %, positive predictive value of 94.1 %, negative predictive value of 94.9 %, accuracy of 94.5 %, and almost perfect precision. Besides, the strips have proved to be viable for using at least 5 years after ptHMIN antigen sensitization. CONCLUSION: Western blot test using ptHMIN provides sensitive, specific, and faster results. Therefore, could be considered a useful tool in the diagnosis of histoplasmosis being used by public health system, even in situations where laboratory facilities are relatively limited.

RESUMEN

PURPOSE: To compare the rates of success of two-dimensional (2D) and three-dimensional (3D) sonographic (US) examinations in locating and adequately visualizing levonorgestrel intrauterine devices (IUDs) and to explore factors associated with the unsuccessful viewing on 2D US. METHODS: Transvaginal 2D and 3D US examinations were performed on all patients 1 month after insertion of levonorgestrel IUDs. The devices were considered adequately visualized on 2D US if both the vertical (shadow, upper and lower extremities) and the horizontal (two echogenic lines) shafts were identified. 3D volumes were also captured to assess the location of levonorgestrel IUDs on 3D US. RESULTS: Thirty women were included. The rates of adequate device visualization were 40% on 2D US (95% confidence interval [CI], 24.6; 57.7) and 100% on 3D US (95% CI, 88.6; 100.0). The device was not adequately visualized in all six women who had a retroflexed uterus, but it was adequately visualized in 12 of the 24 women (50%) who had a nonretroflexed uterus (95% CI, -68.6; -6.8). CONCLUSIONS: We found that 3D US is better than 2D US for locating and adequately visualizing levonorgestrel IUDs. Other well-designed studies with adequate power should be conducted to confirm this finding.

RESUMEN

Essential oils from fresh Piperaceae leaves were obtained by hydrodistillation and analyzed by gas chromatography mass spectrometry (GC-MS), and a total of 68 components were identified. Principal components analysis results showed a chemical variability between species, with sesquiterpene compounds predominating in the majority of species analyzed. The composition of the essential oil of Piper mosenii was described for the first time. The cytotoxicity of the essential oils was evaluated in peritoneal macrophages and the oils of P. rivinoides, P. arboretum, and P. aduncum exhibited the highest values, with cytotoxic concentration at 50% (CC50) > 200 µg/mL. Both P. diospyrifolium and P. aduncum displayed activity against Leishmania amazonensis, and were more selective for the parasite than for the macrophages, with a selectivity index (SI) of 2.35 and >5.52, respectively. These SI values were greater than the 1 for the standard drug pentamidine. The antileishmanial activity of the essential oils of P. diospyrifolium and P. aduncum was described for the first time. P. rivinoides, P. cernuum, and P. diospyrifolium displayed moderate activity against the Mycobacterium tuberculosis H37Rv bacillus, with a minimum inhibitory concentration (MIC) of 125 µg/mL. These results are relevant and suggests their potential for therapeutic purposes. Nevertheless, further studies are required to explain the exact mechanism of action of these essential oils.

RESUMEN

Niemann-Pick type C disease (NPC) is a neurodegenerative genetic disorder caused by accumulation of lipids, especially cholesterol, in the perinuclear space. U18666A is a cholesterol transport-inhibiting agent, being used to mimic NPC, mainly in fibroblasts. The objective of this study was to observe the effect of the drug U18666A, which causes the accumulation of cholesterol in the cytoplasm of astrocytes from newborn rats, on some lysosomal hydrolase activities. Filipin staining and fluorescence microscopy, through CellM software, were used for visualization and quantification of cholesterol. The dose of U18666A that provided the greatest accumulation of cholesterol was that of 0.25 µg/mL in incubation for 48 h. Primary rat astrocytes incubated with the drug (NPC) showed a significantly higher amount of cholesterol than those without U18666A (controls). The measurement of activity of enzymes sphingomyelinase and beta-glucosidase in astrocytes of rats with NPC was significantly lower than that of control astrocytes, which is consistent with the disease in humans. The activity of the enzyme beta-galactosidase showed no significant difference between both groups. We concluded that U18666A appears to be an excellent intracellular cholesterol transport-inhibiting agent affecting some metabolic pathways in astrocytes of young rats, which mimics NPC in these animals. Just like the change in the activity of lysosomal enzymes has been demonstrated, other biochemical parameters of the cell can be tested with this animal model, thus contributing to a better understanding of the disease.

RESUMEN

BACKGROUND: Musculoskeletal chronic pain is a leading cause of global disability and laboral incapacity. However, there is a lack of population-based studies that investigate the relationship between chronic pain and mental disorders with a control group, particularly among low- and middle-income countries. Chronic pain is a serious public health problem in terms of human suffering, and in terms of socioeconomic implications. Frequent association with different mental disorders increases disability, decreases quality of life, and makes diagnosis and treatment challenging. The present study aimed to evaluate the presence of mental disorders in patients with chronic musculoskeletal pain and compare with a control group without pain. METHODS: We selected 100 patients in a regular follow-up at the Musculoskeletal Pain Outpatient Clinic of the University Hospital and compared them with 100 painless individuals from the control group from June 2016 to June 2018. The instruments used were the Mini International Neuropsychiatric Interview (MINI-PLUS) and a structured questionnaire to collect sociodemographic data. Statistical analysis used t-test, chi-square, Fisher's exact test, Mann-Whitney, Kolmogorov-Smirnov tests, and multiple logistic regression. RESULTS: In the sample evaluated, the majority of patients were women (83%), of brown color (54%), with lower-level education (51%), lower salary range (73%) and high absenteeism rate at work (60,7%). Patients with chronic pain had more psychiatric disorders (88% vs. 48% in the control group; p < 0.001). The most frequent diagnoses were anxiety disorders with panic attacks (44%), generalized anxiety (36%), mixed anxiety and depression disorder (33%), social phobia (30%), agoraphobia (29%), suicide risk (28%), and major depression (27%). CONCLUSION: Positive correlations of mental disorders and chronic musculoskeletal pain have been documented. This suggests that psychiatric components must be taken into account in the management of chronic pain syndromes. The use of Mini Plus as a diagnostic tool for psychiatric disorders can contribute to optimizing the diagnosis and treatment of patients with chronic pain and encourage the creation of policies with strategies and criteria for quick access to Multi-professional Services.

RESUMEN

The present article analyzes the transfers from parliamentary amendments by the Ministry of Health to municipalities to finance public health actions and services from 2015 to 2021. A descriptive and exploratory study was carried out with secondary data, including all Brazilian cities. Resources from amendments showed an increase, particularly from 2018 onwards, indicating the expansion of their relevance for financing SUS. From 2016 to 2021, over 80% was allocated to municipalities, representing 9.5% of all federal transfers, with 91.2% for operational expenses. Transfers from amendments differ from regular transfers due to greater instability and per capita variation among the amounts collected by municipalities and due to the fact that they allocate most resources to the Northeast and primary care to the detriment of the Southeast and medium and high complexity care. These transfers represent a differentiated modality of resource allocation in SUS that produces new distortions and asymmetries, with implications for intergovernmental relations, as well as between the executive and legislative powers, increasing the risk of the discontinuity of actions and services and imposing challenges for the municipal management.


O artigo tem como objetivo analisar as transferências por emendas parlamentares do Ministério da Saúde aos municípios para o financiamento de ações e serviços públicos de saúde, de 2015 a 2021. Foi realizado estudo descritivo e exploratório com dados secundários, abrangendo a totalidade de municípios brasileiros. Os recursos provenientes de emendas apresentaram aumento, em especial a partir de 2018, indicando a expansão de sua relevância para o financiamento do SUS. No período de 2016 a 2021, mais de 80% foram alocados aos municípios, representando 9,5% dos repasses federais, com 91,2% de natureza de custeio. As transferências por emendas diferem dos repasses regulares por possuir maior instabilidade e variação per capita entre os montantes captados pelos municípios, e por destinar a maior parte dos recursos ao Nordeste e à atenção primária, em detrimento do Sudeste e da média e alta complexidade. Configura-se uma modalidade diferenciada de alocação de recursos no SUS que produz novas distorções e assimetrias, com implicações para as relações intergovernamentais e entre os poderes executivo e legislativo, ampliando o risco de descontinuidade de ações e serviços e impondo desafios para as gestões municipais.

RESUMEN

Disasters cause changes in morbidity, mortality, and medicine use. Brazil is one of the main producers of mineral ores at great environmental cost. Mine tailings are stored in dams and ruptures have led to major disasters. We investigated the consumption of psychoactive medicines in the municipalities affected by the Fundão dam disaster in Minas Gerais State. An ecological study was carried out on drug consumption, estimated using public purchases in Minas Gerais and dispensing data from private retail pharmacies. Consumption (in number of defined daily doses/100,000 inhabitants per day) was analyzed descriptively in eight municipalities, stratified according to consumption level during a 25-month period. Six comparisons of mean consumption values for both data sets were done for pre- and post-disaster periods. The means of medicine consumption before and after the event were plotted and linear trends were added. Public purchase data evinced high consumption levels. Only pharmaceutical retail showed significant differences between the strata in the pre-disaster versus two post-disaster periods. Smaller municipalities showed an increase in consumption 15 months after the disaster. Clonazepam led the way in pharmaceutical retail consumption, followed by fluoxetine. Medicines showed an upward trend after the disaster. The high public provision may have stifled significant consumption patterns of psychoactive drugs; however, peak consumption were observed in private retail, suggesting a modification in use patterns after the disaster. The decrease in consumption immediately after the event was probably related to lower care-seeking behavior on the part of the population, and significant peaks after the disaster may reflect economic consequences of it.

RESUMEN

BACKGROUND AND OBJECTIVE: Long COVID (LC) refers to persistent symptoms after acute COVID-19 infection, which may endure for months or years. LC affects millions of people globally, with substantial impacts on quality of life, employment, and social participation. Ensuring access to effective, patient-centered care for LC demands evidence, grounded in inclusive representation of those affected by the condition. Yet survey studies frequently under-represent people with the most disabling disease presentations and racially and socio-economically marginalized groups. We aimed to describe a patient-engaged approach to developing a survey to inform public LC healthcare, and to assess its implementation in terms of enabling participation by diverse LC patients in Brazil. METHODS: Survey development was iterative, achieved through an interdisciplinary collaboration among researchers including people living with LC, and grounded in three guiding principles: (1) evidence-based; (2) inclusive, intersectional, and patient-centered understanding of chronic illness and research participation; and (3) sensitivity to the context of healthcare access. RESULTS: The product of our collaboration was a longitudinal survey using a questionnaire assessing: LC symptoms; their clinical and functional evolution; and impacts on quality of life, household income, health service access, utilization, and out-of-pocket expenses. We illustrate how we operationalized our three principles through survey content, instrument design, and administration. 651 participants with diverse LC symptoms, demography, and socio-economic status completed the survey. We successfully included participants experiencing disabling symptoms, Black and mixed race participants, and those with lower education and income. CONCLUSION: By centering patient experience, our novel, principles-based approach succeeded in promoting equity, diversity, and inclusion in LC survey research. These principles guiding patient-engaged collaboration have broad transferability. We encourage survey researchers working on chronic illness and in other contexts of marginalization and inequality to adopt them.

RESUMEN

This work aimed to analyze graduates' profiles, education's effects, and the professional trajectory of those who completed lato sensu courses at Fiocruz. A total of 1,620 graduates participated in 79 courses completed in the 2013-2020 period. A questionnaire was applied before the course and after its completion. A description of the absolute and relative frequency of the variables was realized. A binary logistic regression model was developed to identify variables associated with the positive impact of the course. The odds ratio and its 95% confidence interval were the measures used. Among graduates with a positive impact from the course, those with black/brown skin color are 40% more likely to have a positive impact from the course than those with white skin color; those who have other academic education before the course are 1.5 times more likely than those who have no previous education; those who changed their professional activity as a result of the course are 3.3 more likely than those who were not working; those who reported that the course was closely related to their professional activity were 5.7 more likely than those who reported that the course had poor or no relationship. Every one-year increase since graduation increased the likelihood of the course's positive impact by 14%.


O objetivo da pesquisa foi analisar o perfil dos egressos, os efeitos da formação e a trajetória profissional dos que concluíram cursos presenciais de Especialização da Fiocruz. Participaram 1.620 egressos de 79 cursos concluídos entre 2013 e 2020. Foi aplicado questionário antes do ingresso e após o término do curso. Foi realizada descrição da frequência absoluta e relativa das variáveis e desenvolvido modelo de regressão logística binária para identificar variáveis associadas ao impacto positivo do curso. A razão de chance e seu intervalo de confiança de 95% foram as medidas utilizadas. Entre os egressos com impacto positivo do curso concluído: aqueles com cor de pele preta ou parda têm cerca de 40% mais chance de ter impacto positivo do curso do que os de cor de pele branca; os que têm outra formação acadêmica antes do curso têm 1,5 vez mais chance do que os que não têm outra formação anterior, aqueles que mudaram a atividade profissional em função do curso têm 3,3 mais chance do que os que não estavam trabalhando, os que informaram que o curso estava muito relacionado à atividade profissional têm 5,7 mais chance do que os que relataram que o curso teve pouca ou nenhuma relação; e cada acréscimo de 1 ano no tempo de formado aumenta em 14% a chance do impacto positivo do curso.

RESUMEN

This study evaluated the inclusion of nanofibers from soybean hulls and pupunha peach palm heart sheaths in the diet of growing rabbits. Twenty-four New Zealand White rabbits (male and female) were allocated in three experimental groups: control, fed a basal diet; Nanosoy, fed a diet containing 7% soybean-hull nanofibers; and Nanopupunha, fed a diet containing 7% pupunha palm heart-sheath nanofibers. The Nanosoy-group rabbits showed poorer final weight, daily feed intake, and daily weight gain than those in other groups. In the duodenum, villus height, total mucosal thickness, and villus width were higher in rabbits that received nanofiber-supplemented diets than in the controls. Higher villus density and wall thickness were observed in Nanopupunha-fed rabbits than in the controls. In the jejunum, although the crypt depth was higher in Nanosoy-fed rabbits, the villus height:crypt depth ratio was higher in the Nanopupunha-fed group. Nanosoy-fed animals exhibited increased count Enterobacteriaceae populations. Rabbits in both nanofiber-fed groups exhibited higher lactic-acid bacterial counts than those in the control-diet group. Therefore, although the inclusion of 7% Nanopupunha in the diet of rabbits did not alter the performance, it improved intestinal health and increased the lactic-acid bacterial count in the cecum of growing rabbits.

RESUMEN

Background: Most cancer drugs enter the US market first. US Food and Drug Administration (FDA) approvals of new cancer drugs may influence regulatory decisions in other settings. The study examined whether characteristics of available evidence at FDA approval influenced time-to-marketing authorisation (MA) in Brazil, and price differences between the two countries. Methods: All new FDA-approved cancer drugs from 2010 to 2019 were matched to drugs with MA and prices approved in Brazil by December 2020. Characteristics of main studies, availability of randomised controlled trials (RCTs), overall survival (OS) benefit, added therapeutic benefit, and prices were compared. Findings: Fifty-six FDA-approved cancer drugs with matching indications received a MA at the Brazilian Health Regulatory Agency (Anvisa) after a median of 522 days following US approval (IQR: 351-932). Earlier authorisation in Brazil was associated with availability of RCT (median: 506 vs 760 days, p = 0.031) and evidence of OS benefit (390 vs 543 days, p = 0.019) at FDA approval. At Brazilian marketing authorisation, a greater proportion of cancer drugs had main RCTs (75% vs 60.7%) and OS benefit (42.9% vs 21.4%) than that in the US. Twenty-eight (50%) drugs did not demonstrate added therapeutic benefit over drugs for the same indication in Brazil. Median approved prices of new cancer drugs were 12.9% lower in Brazil compared to the US (adjusted by Purchasing Power Parity). However, for drugs with added therapeutic benefit median prices were 5.9% higher in Brazil compared to the US, while 17.9% lower for those without added benefit. Interpretation: High-quality clinical evidence accelerated the availability of cancer medicines in Brazil. The combination of marketing and pricing authorisation in Brazil may favour the approval of cancer drugs with better supporting evidence, and more meaningful clinical benefit albeit with variable degree of success in achieving lower prices compared to the US. Funding: None.

RESUMEN

The effects of inspiratory muscle training on functional capacity and quality of life in functional class III and IV heart failure patients were evaluated. The inspiratory muscle training protocol was applied to 20 patients with heart disease, over a period of 6 weeks, 3 times a week, for 30 minutes, with a load of 40% of the maximum inspiratory pressure and 5 sets of 10 repetitions, with an interval of 1-2 minutes. The Minnesota Quality of Life Questionnaire, the 6-minute walk test, vital data and manovacuometry (pre- and post-intervention) were used. Pre- and post-test comparisons revealed significant differences in the 6-minute walk test, heart rate, respiratory rate, Borg scale, respiratory muscle strength, and systolic and diastolic blood pressure, and an increase in quality of life was also observed (P < 0.01). Inspiratory muscle training improved functional capacity and quality of life, suggesting that inspiratory muscle training should be included in Class III and IV cardiac rehabilitation.

RESUMEN

The scope of the article was to characterize the process of regulation of care in Primary Health Care units in the city of Rio de Janeiro, with an emphasis on the outpatient dimension. A cross-sectional study was carried out in 2019, by means of a survey, with the participation of 114 local regulatory physicians. With respect to the profile of local regulators, there is a high percentage with training in Family and Community Medicine and the length of service of these professionals in the units is relatively satisfactory. For 52.6%, the infrastructure for regulation is adequate, but connectivity frequently presents problems. In the regulation system, the mechanisms and schedules for making vacancies available and accessing them elicit competition between the regulators of the units, with work overload and associated access inequities. There was major involvement of local regulators in activities of evaluation and management of waiting times. The majority reported that there was little or no interaction with specialized care. Although the decentralized regulation process still has some shortcomings, the study points to the feasibility and contribution of more intense participation of Primary Care in the regulation of access.


O artigo teve por objetivo caracterizar o processo de regulação assistencial realizado nas unidades de Atenção Primária à Saúde do município do Rio de Janeiro, com ênfase na dimensão ambulatorial. Foi realizado estudo transversal, por meio de um survey, com participação de 114 médicos reguladores locais, no ano de 2019. Quanto ao perfil dos reguladores locais, destacou-se o alto percentual com formação em Medicina de Família e Comunidade e o tempo de atuação relativamente adequado destes profissionais nas unidades. Para 52,6%, a infraestrutura para regulação é adequada, mas a conectividade apresenta problemas com frequência. No sistema de regulação, os mecanismos e horários de disponibilização de vagas produzem competição entre os reguladores das unidades, com sobrecarga de trabalho e iniquidades de acesso associadas. Observou-se importante envolvimento dos reguladores locais em atividades de avaliação e gestão de filas de espera. A maioria informou haver pouca ou nenhuma interação com a atenção especializada. Apesar do processo de regulação descentralizada ainda apresentar importantes limites, o estudo aponta a factibilidade e contribuição da entrada mais intensa da Atenção Primária na regulação do acesso.
