ABSTRACT Objective: To compare the glucose metabolism of patients with chronic hepatitis C virus infection treated with direct-acting antivirals (DAAs) in pretreatment and sustained viral response (SVR) periods. Materials and methods: This was an intervention pre-post study of 273 patients with chronic hepatitis C virus infection treated with DAAs from March 2018 to December 2019. Glycidic metabolism was evaluated through homeostasis model assessment (HOMA) – insulin resistance (IR) and HOMA-β indices and assessments of insulinemia and HbA1c levels. These parameters were analyzed with a T test by paired comparison of the means of the variables and Wilcoxon's test paired for the median; in the variables with an abnormal distribution, the Z score was generated for the mean in both the pretreatment and SVR periods. Statistical significance was considered at p ≤ 0.05. Results: Among 273 participants, 125 (45.8%) had prediabetes, and 50 (18.3%) had diabetes. In SVR, there was a significant increase in platelets, albumin, alkaline phosphatase, cholesterol and triglycerides and a significant decrease in aspartate aminotransferase, alanine aminotransferase, gamma GT and bilirubin. The HOMA-IR and HOMA-β indices increased in SVR from 1.95 to 2.29 (p = 0.087) and 71.20 to 82.60 (p = 0.001), respectively. Insulinemia increased from 7.60 μU/mL to 8.90 μU/mL (p = 0.011). HbA1c decreased from 5.6 to 5.4 (p < 0.001). Among patients with prediabetes and those with diabetes, the reduction in HbA1c values was significant (p = 0.006 and p = 0.026, respectively). Conclusion: SVR significantly impacts and leads to improvement in glucose metabolism in patients with chronic liver disease induced by hepatitis C virus.

Abstract Objective To compare the use of mirabegron with anticholinergics drugs for the treatment of overactive bladder (OB). Data Source Systematic searches were conducted in EMBASE, PUBMED, Cochrane, and LILACS databases from inception to September 2021. We included RCTs, women with clinically proven OB symptoms, studies that compared mirabegron to antimuscarinic drugs, and that evaluated the efficacy, safety or adherence. Data Collection RevMan 5.4 was used to combine results across studies. We derived risk ratios (RRs) and mean differences with 95% CIs using a random-effects meta-analytic model. Cochrane Collaboration Tool and GRADE was applied for risk of bias and quality of the evidence. Data Synthesis We included 14 studies with a total of 10,774 patients. Fewer total adverse events was reported in mirabegron group than in antimuscarinics group [RR 0.93 (0.89–0.98)]. The risk of gastrointestinal tract disorders and dry mouth were lower with mirabegron [RR 0,58 (0.48–0.68); 9375 patients; RR 0.44 (0.35–0.56), 9375 patients, respectively]. No difference was reported between mirabegron and antimuscarinics drugs for efficacy. The adherence to treatment was 87.7% in both groups [RR 0.99 (0.98–1.00)]. Conclusion Mirabegron and antimuscarinics have comparable efficacy and adherence rates; however, mirabegron showed fewer total and isolated adverse events.

Resumo Objetivo Comparar o uso de mirabegrom com anticolinérgicos para o tratamento da bexiga hiperativa (BH). Fonte de Dados Buscas sistemáticas foram realizadas nas bases de dados EMBASE, PUBMED, Cochrane e LILACS desde o início até setembro de 2021. Incluímos ECR, mulheres com sintomas de BH clinicamente comprovados, estudos que compararam mirabegrom a medicamentos antimuscarínicos e avaliaram a eficácia, segurança ou adesão. Coleta de Dados RevMan 5.4 foi usado para combinar os resultados entre os estudos. Derivamos razões de risco (RRs) e diferenças médias com intervalo de confiança (IC) de 95% usando um modelo meta-analítico de efeitos aleatórios. Cochrane Collaboration Tool e GRADE foi aplicado para risco de viés e qualidade da evidência. Síntese dos Dados Foram incluídos 14 estudos com um total de 10.774 pacientes. Menos eventos adversos totais foram relatados no grupo mirabegrom do que no grupo antimuscarínicos [RR: 0,93 (0,89–0,98)]. O risco de distúrbios do trato gastrointestinal e boca seca foram menores com mirabegrom [RR: 0,58 (0,48–0,68); 9.375 pacientes; RR: 0,44 (0,35–0,56), 9.375 pacientes, respectivamente]. Nenhuma diferença foi relatada entre mirabegrom e drogas antimuscarínicos para eficácia. A adesão ao tratamento foi de 87,7% em ambos os grupos [RR: 0,99 (0,98–1,00)]. Conclusão Mirabegrom e antimuscarínicos têm eficácia e taxas de adesão comparáveis, porém o mirabegrom apresentou menos eventos adversos totais e isolados.

Resumo A heterogeneidade e vulnerabilidade da população em situação de rua revelam a complexidade de viver nessa condição e exige que o Estado tenha papel fundamental na oferta de políticas de saúde e assistência social. O objetivo do estudo, a partir de uma revisão integrativa da literatura, foi avaliar a intersetorialidade entre políticas de saúde, proteção social e ações da sociedade civil organizada para a população em situação de rua no Brasil. Foi realizada uma busca nas bases SciELO, Lilacs e PubMed, sendo selecionados dez artigos, publicados entre 2004-2021, todos de caráter qualitativo. Observou-se indícios da intersetorialidade entre as políticas para a população em situação de rua, descritas principalmente como uma ponte de acesso entre os serviços ofertados. Entretanto, as intervenções ainda são pouco exploradas e sistematizadas. Nesse sentido, recomenda-se que estudos de impacto voltados à avaliação de políticas públicas intersetoriais sejam desenvolvidos para que se permita a avaliação da efetividade da intersetorialidade entre os serviços de saúde, assistência social e sociedade civil organizada na qualidade de vida da população em situação de rua.

Abstract The heterogeneous and vulnerable nature of the unhoused population reveal the complexity of living on the street and call for the State to play a fundamental role in the provision of health and social care policies. The scope of this study was to evaluate the intersectorality between health policies, social protection and organized civil society actions for the unhoused population in Brazil, based on an integrative literature review. To achieve this, a search was conducted in the SciELO, LILACS and PubMed databases, from which ten articles published between 2004-2021, all of a qualitative nature, were selected. From the analysis of the chosen articles, the evidence of intersectorality between the policies for the unhoused population was observed, mainly described as a point of intersection between the services offered. However, interventions are still poorly explored and systematized. It is recommended that quantitative studies aimed at the evaluation of intersectoral public policies be developed to allow the assessment of the impact of intersectorality between health services, social assistance and organized civil society on the quality of life of the unhoused population.

O objetivo deste artigo é desenvolver um índice de priorização para aceleração do cumprimento das metas nacionais de saúde propostas pela Agenda 2030. Trata-se de estudo ecológico que abordou as Regiões de Saúde do Brasil. O índice incorporou 25 indicadores com proximidade analítica aos indicadores oficiais da Agenda 2030, para os quais existem dados de fontes públicas no nível municipal para o período de 2015 a 2019. O índice apresentou-se como potente método para apoiar a decisão da gestão em saúde. Os resultados permitiram identificar que a Região Norte do país apresenta os territórios mais vulneráveis e, portanto, prioritários para a alocação de recursos. Além disso, a análise dos subíndices permitiu destacar os gargalos locais de saúde, reforçando a necessidade de os municípios de cada região estabelecerem suas próprias prioridades na decisão de alocação dos recursos da saúde. Ao indicar as Regiões de Saúde e os temas prioritários para maiores investimentos, esta investigação aponta caminhos que podem apoiar a implementação da Agenda 2030 do nível local ao nacional, além de fornecer elementos por meio dos quais os formuladores de políticas podem minimizar os efeitos das iniquidades sociais sobre a saúde, priorizando os territórios com piores índices.

Además, el análisis de los subíndices permitió resaltar cuellos de botella locales en salud, reforzando la necesidad de que los municipios de cada región establezcan sus propias prioridades en la decisión de asignación de recursos en salud. Al indicar las Regiones de Salud y los temas prioritarios para mayores inversiones, esta investigación apunta caminos que pueden apoyar la implementación de la Agenda 2030 desde el nivel local al nacional, además de proporcionar elementos a través de los cuales los formuladores de políticas pueden minimizar los efectos de las inequidades sociales sobre la salud, priorizando los territorios con peores índices.

This study aimed to develop a prioritization index to speed up the achievement of national health targets proposed in the 2030 Agenda. This is an ecological study that addressed the Health Regions in Brazil. The index incorporated 25 indicators with analytical proximity to the official indicators of the 2030 Agenda whose data are available from public municipal sources for the period of 2015-2019. According to our study, the index was a powerful method to support health management decisions. The results showed the most vulnerable territories are located in the North Region of the country, and therefore, these are priority areas for resource allocation. The analysis of subindices highlighted local health bottlenecks, reinforcing the need for municipalities in each region to set their own priorities while making decisions for health resource allocation. By indicating Health Regions and priority themes for more investments, this investigation shows paths to support the implementation of the 2030 Agenda, from the local to the national level, in addition to providing elements that can be used by policy makers to minimize the effects of social inequalities on health, prioritizing territories with worse indices.

Abstract Few long-term studies assess the discoloration induced by hydraulic calcium silicate-based cement on dental structures. In addition, as far as we know, no long-term study has assessed the discoloration induced by these cement on composite resin. Objective This in vitro study aimed to assess, during a period of two years, the discoloration potential of different hydraulic calcium silicate-based cements (hCSCs) on the enamel/dentin structure and composite resin restoration. Methodology A total of 40 enamel/dentin discs were obtained from bovine incisors, and 40 composite resin discs (10 mm in diameter × 2 mm thick) were fabricated. A 0.8 mm-deep cavity was made in the center of each disc and filled with the following hCSCs (n=10): Original MTA (Angelus); MTA Repair HP (Angelus); NeoMTA Plus (Avalon); and Biodentine (Septodont). An initial color measurement was performed (T0 - baseline). After 7, 15, 30, 45, 90, 300 days, and two years, new color measurements were performed to determine the color (ΔE00), lightness (ΔL’), chroma (ΔC’), hue differences (ΔH’), and whiteness index (WID). Results For enamel/dentin, the ΔE00 was significant among groups and periods (p<0.05). NeoMTA Plus had the greatest ΔE00. The NeoMTA Plus group had the greatest ΔE00 after two years for composite resin. Significant reduction in lightness was observed for all groups after two years (p<0.05). The most significant WID values were observed after 30 days for Biodentine (enamel/dentin) and MTA Repair HP groups (composite resin) (p<0.05). Conclusions The hCSCs changed the colorimetric behavior of both substrates, leading to greater darkening over time. The Bi2O3 in the Original MTA seems relevant in the short periods of color change assessment.

Abstract Accumulated evidence has shown that the oral cavity may be an important reservoir for SARS-CoV-2. Some authors have suggested that the use of mouthrinses could reduce SARS-CoV-2 viral load in the saliva. Thus, the aim of this review was to synthesize evidence about the efficacy of mouthrinses in reducing the salivary viral load of SARS-CoV-2. 2. Nine randomized controlled trials (RCTs) have investigated the efficacy of different mouthrinses in reducing salivary SARS-CoV-2 loads. Various active ingredients have been tested in these trials: 0.5%,1% and 2% povidone-iodine, 0.2% and 0.12% chlorhexidine (CHX), 0.075% cetylpyridinium chloride (CPC), 0.075% CPC with Zinc lactate, 1% and 1.5% hydrogen peroxide (HP), 1.5% HP + 0.12% CHX and ß-cyclodextrin and citrox. The studies reported an intra-group reduction in the salivary levels of the virus, when compared with the baseline. However, the majority of these trials failed to demonstrate a significant inter-group difference between active groups and the control group relative to the decrease in salivary SARS-CoV-2 loads. Although promising, these results should be confirmed by larger trials.

SUMMARY OBJECTIVE: The objective of this study, carried out at the university hospital of the Federal University of Rio Grande, was to assess whether the treatment of chronic hepatitis C with direct-acting antivirals and the sustained virological response will affect the metabolic influences of the hepatitis C virus and whether these effects will vary according to genotypes and virus load. METHODS: This is an intervention pre-post study, carried out from March 2018 to December 2019, evaluating 273 hepatitis C virus patients treated with direct-acting antivirals. Inclusion criteria included being monoinfected with hepatitis C virus and achieving sustained virological response . Exclusion criteria included the presence of decompensated cirrhosis or co-infected with hepatitis B virus or human immunodeficiency virus. Genotypes, genotype 1 subtypes, and hepatitis C virus viral load were analyzed. Glucose metabolism was evaluated by the Homeostasis Model Assessment-insulin resistance indices: Homeostasis Model Assessment-β, TyG, and HbA1c, measured at the beginning of treatment and in sustained virological response. Statistical analysis with a T test by paired comparison of the means of the variables in the pretreatment and in the sustained virological response. RESULTS: Homeostasis Model Assessment-insulin resistance analysis: there were no significant differences between pretreatment and sustained virological response. Homeostasis Model Assessment-β analysis: significant increase in genotype 1 patients (p<0.028). TyG index analysis: significant increase in genotype 1b (p<0.017), genotype 3 (p<0.024), and genotype non-1 with low viral load (p<0.039). HbA1c analysis: significant decrease in genotype 3 (p<0.001) and genotype non-1 patients with low viral load (p<0.005). CONCLUSION: We detected significant metabolic influences after sustained virological response: impairment in lipid profile and improvements in the glucose metabolism. We found significant differences in genotype dependence, genotype 1 subtypes, and viral load.

BACKGROUND Chikungunya is a mosquito-borne virus that has been causing large outbreaks in the Americas since 2014. In Brazil, Asian-Caribbean (AC) and East-Central-South-African (ECSA) genotypes have been detected and lead to large outbreaks in several Brazilian states. In Rio Grande do Sul (RS), the southernmost state of Brazil, the first cases were reported in 2016. OBJECTIVES AND METHODS We employed genome sequencing and epidemiological investigation to characterise the Chikungunya fever (CHIKF) burden in RS between 2017-2021. FINDINGS We detected an increasing CHIKF burden linked to travel associated introductions and communitary transmission of distinct lineages of the ECSA genotype during this period. MAIN CONCLUSIONS Until 2020, CHIKV introductions were most travel associated and transmission was limited. Then, in 2021, the largest outbreak occurred in the state associated with the introduction of a new ECSA lineage. CHIKV outbreaks are likely to occur in the near future due to abundant competent vectors and a susceptible population, exposing more than 11 million inhabitants to an increasing infection risk.

Abstract Background Data on post-acute COVID-19 in autoimmune rheumatic diseases (ARD) are scarce, focusing on a single disease, with variable definitions of this condition and time of vaccination. The aim of this study was to evaluate the frequency and pattern of post-acute COVID-19 in vaccinated patients with ARD using established diagnosis criteria. Methods Retrospective evaluation of a prospective cohort of 108 ARD patients and 32 non-ARD controls, diagnosed with SARS-CoV-2 infection (RT-PCR/antigen test) after the third dose of the CoronaVac vaccine. Post-acute COVID-19 (≥ 4 weeks and > 12 weeks of SARS-CoV-2 symptoms) were registered according to the established international criteria. Results ARD patients and non-ARD controls, balanced for age and sex, had high and comparable frequencies of ≥ 4 weeks post-acute COVID-19 (58.3% vs. 53.1%, p = 0.6854) and > 12 weeks post-acute COVID-19 (39.8% vs. 46.9%, p = 0.5419). Regarding ≥ 4 weeks post-acute COVID-19, frequencies of ≥ 3 symptoms were similar in ARD and non-ARD controls (54% vs. 41.2%, p = 0.7886), and this was also similar in > 12 weeks post-acute COVID-19 (68.3% vs. 88.2%, p = 0.1322). Further analysis of the risk factors for ≥ 4 weeks post-acute COVID-19 in ARD patients revealed that age, sex, clinical severity of COVID-19, reinfection, and autoimmune diseases were not associated with this condition (p > 0.05). The clinical manifestations of post-acute COVID-19 were similar in both groups (p > 0.05), with fatigue and memory loss being the most frequent manifestations. Conclusion We provide novel data demonstrating that immune/inflammatory ARD disturbances after third dose vaccination do not seem to be a major determinant of post-acute COVID-19 since its pattern is very similar to that of the general population.

Resumen Introducción: Momordica charantia L. es ampliamente utilizada para consumo y medicina tradicional debido a sus actividades biológicas. Sin embargo, se sabe poco sobre los efectos del melón amargo en las células sanas. Por lo tanto, nuestro objetivo fue evaluar los efectos del extracto de Momordica charantia en linfocitos humanos aislados, especialmente en aspectos inflamatorios, citotóxicos, genotóxicos y mutagénicos. Método: Para ello se preparó un extracto hidroetanólico con frutos y semillas y se procedió a la identificación y cuantificación fitoquímica. Los linfocitos humanos purificados se expusieron a 12,5; 25; 50 µg/mL de extracto de Momordica charantia durante 24 horas y después de este período. Resultados: Los datos mostraron que el extracto de Momordica charantia no indujo citotoxicidad, alteraciones en la frecuencia de micronúcleos, ni actividad de interleucina-6, interleucina-10 ciclooxigenasa-2 y producción de óxido nítrico; sin embargo, causó daño en el ADN y una disminución de TNF-α en las condiciones experimentales y células aplicadas. Conclusiones: Nuestros datos proponen un proceso antiinflamatorio generado por Momordica charantia mediado por la reducción de TNF-α.

Abstract Introduction: Momordica charantia L. is widely used for consumption and traditional medicine due to its biological activities. Nevertheless, little is known about the effects of bitter melon on healthy cells. Hence, we aimed to evaluate the effects of Momordica charantia extract in human isolated lymphocytes, especially on inflammatory, cytotoxicity, genotoxicity, and mutagenicity aspects. Method: For this, we prepared a hydroethanolic extract with fruits and seeds and proceeded with phytochemical identification and quantification. The human purified lymphocytes were exposed to 12.5, 25, and 50 µg/mL of Momordica charantia extract for 24h and, after this period. Results: The data showed that the Momordica charantia extract did not induce cytotoxicity, micronucleus frequency alterations, or interleukin-6, interleukin-10 cyclooxygenase-2 activity and the production of nitric oxide; however, it caused DNA damage and a decrease of TNF-α under the experimental conditions and cells applied. Conclusions: Our data propose an anti-inflammatory process generated by Momordica charantia mediated by TNF-α reduction.

Abstract Background: Therapeutic hypothermia is used in adults and neonates after cardiac arrest, but its efficiency in children under 18 years old is still uncertain. Objective: To evaluate the effectiveness and risks of therapeutic hypothermia after cardiac arrest in children under 18 years of age through a systematic review. Methods: A systematic review was performed in January 2022 in the MEDLINE, SciELO, Cochrane, and LILACS databases. Inclusion criteria: randomized controlled trials (RCTs) performed in humans. Articles from other typologies, published more than 10 years ago, or with volunteers over 18 years old were excluded. Results: Four studies were identified, of which 3 were analyzed; all of them were of moderate quality according to the Jadad Scale and the Cochrane Collaboration tool. The studies indicated that lowering the temperature did not improve data on mortality and adverse events. Two studies did not identify statistically significant differences (p > 0.05) considering hypothermia in relation to normothermia in terms of survival, safety, and global neurobehavioral and cognitive function. The other study did not show improved serum biomarker concentrations. Conclusion: The results found in this review do not support the use of therapeutic hypothermia after pediatric cardiac arrest, as this intervention did not provide any apparent benefits in terms of safety, adverse events, survival, and neurological impact. We recommend the conduction of new RCTs using the measurement of serum biomarkers to better evaluate the effectiveness of the intervention.

ABSTRACT Introduction: experimental animal models provide valuable information to understand the physiological and pathological processes of blood vessel injuries and their consequences. Objective: to analyze the histological and morphometric changes observed in the abdominal aorta of Wistar rats subjected to a hyperglycemic diet. Methods: two experimental groups of 10 animals each were randomly formed. The control group was fed with a standard diet for this species, and the experimental group was fed with a standard diet plus 35% sucrose, as drinking water from weaning to 20 weeks of life. The study was performed on aortic samples fixed and processed by the classic paraffin embedding technique and stained with the hematoxylin-eosin and Verhoeff techniques. The description of the layers of the arterial wall and the determination of morphometric variables in each histological slide were made. Results: the Wistar rats belonging to the experimental group developed incipient changes in the arterial wall of the abdominal aorta, which correspond to the presence of endothelial cell swelling and vacuolation in the vascular smooth muscle cell, as well as marked disorganization of the muscle and elastic fibers of the middle layer. The morphometric variables that showed significant differences between the groups were the thickness of the tunica media and the media/lumen ratio. Conclusions: the middle wall turned out to be the most affected layer, demonstrating the harmful effect of the hyperglycemic diet on the arterial wall.

RESUMEN Introducción: Los modelos experimentales en animales proporcionan una valiosa información para comprender los procesos fisiopatológicos de las lesiones de los vasos sanguíneos y sus consecuencias. Objetivo: Analizar los cambios histológicos y morfométricos que se observaron en la aorta abdominal de las ratas Wistar sometidas a una dieta hiperglucídica. Métodos: Se formaron aleatoriamente dos grupos experimentales de 10 animales cada uno. El grupo control alimentado con dieta estándar para la especie, y el grupo experimental alimentado con dieta estándar más sacarosa al 35 %, como agua de bebida desde el destete hasta las 20 semanas de vida. El estudio se realizó en muestras de aorta fijadas y procesadas por la técnica clásica de inclusión en parafina y coloreadas con las técnicas de hematoxilina - eosina y Verhoeff. Se realizó la descripción de las capas de la pared arterial y la determinación de variables morfométricas en cada lámina histológica. Resultados: Las ratas Wistar pertenecientes al grupo experimental desarrollaron modificaciones incipientes en la pared arterial de la aorta abdominal, las cuales corresponden con la presencia de tumefacción en la célula endotelial y vacuolización en la célula muscular lisa vascular, así como marcada desorganización de las fibras elásticas y musculares de la capa media. Las variables morfométricas que mostraron diferencias significativas entre los grupos fueron el grosor de la túnica media y el cociente media/ lumen. Conclusiones: La pared media resultó ser la capa más afectada demostrándose el efecto nocivo de la dieta hiperglucídica en la pared arterial.
