RESUMO

OBJECTIVES: [51Cr]CrEDTA is used to measure the Glomerular Filtration Rate (GFR) in different clinical conditions. However, there is no consensus on the ideal number of blood samples to be taken and at what time points to measure its clearance. This study aimed to compare Slope Intercept (SI) and Single-Sample (SS) methods for measuring GFR in patients with solid tumors, stratified by age, GFR, and Body Mass Index (BMI). METHODS: 1,174 patients with cancer were enrolled in this prospective study. GFR was calculated by the SI method using blood samples drawn 2-, 4-, and 6-hours after [51Cr]CrEDTA injection (246-GFR). GFR was also measured using the SI method with samples at 2 and 4 hours (24-GFR) and at 4 and 6 hours (46-GFR), and SS methods according to Groth (4Gr-GFR) and Fleming (4Fl-GFR). Statistical analysis was performed to assess the accuracy, precision, and bias of the methods. RESULTS: Mean 246-GFR was 79.2 ± 21.9 mL/min/1.73 m2. ANOVA indicated a significant difference between 4Gr-GFR and the reference 246-GFR. Bias was lower than 5 mL/min/1.73 m2 for all methods, except for SS methods in subgroups BMI > 40 kg/m2; GFR > 105 or < 45. Precision was adequate and accuracy of 30 % was above 98% for all methods, except for SS methods in subgroup GFR < 45. CONCLUSION: 46-GFR and 246-GFR have high agreement and may be used to evaluate kidney function in patients with solid tumors. Single-sample methods can be adopted in specific situations, for non-obese patients with expected normal GFR.

RESUMO

Accurate assessment of glomerular filtration rate (GFR) is crucial to guiding drug eligibility, dosing of systemic therapy, and minimizing the risks of both undertreatment and toxicity in patients with cancer. Up to 32% of cancer patients have baseline chronic kidney disease (CKD), and both malignancy and treatment may cause kidney injury and subsequent CKD. To date, there has been lack of guidance to standardize approaches to GFR estimation in the cancer population. In this two-part statement from the American Society of Onco-Nephrology, we present key messages for estimation of GFR in patients with cancer, including the choice of GFR estimating equation, use of race and body surface-area (BSA)-adjustment, and anticancer drug dose-adjustment in the setting of CKD. These key messages are based on a systematic review of studies assessing GFR estimating equations using serum creatinine and cystatin C in patients with cancer, against a measured GFR comparator. The preponderance of current data involving validated GFR estimating equations involves the CKD-EPI equations, with 2,508 patients in whom CKD-EPI using serum creatinine and cystatin C was assessed (8 studies) and 15,349 in whom CKD-EPI with serum creatinine was assessed (22 studies). The former may have improved performance metrics and be less susceptible to shortfalls of eGFR using serum creatinine alone. Since included studies were moderate quality or lower, the ASON Position Committee rated the certainty of evidence as low. Additional studies are needed to assess the accuracy of other validated eGFR equations in patients with cancer. Given the importance of accurate and timely eGFR assessment we advocate for the use of validated GFR estimating equations incorporating both serum creatinine and cystatin C in patients with cancer. Measurement of GFR via exogenous filtration markers should be considered in patients with cancer for whom eGFR results in borderline eligibility for therapies or clinical trials.

RESUMO

All non-Mimosoid nodulated genera in the legume subfamily Caesalpinioideae confine their rhizobial symbionts within cell wall-bound 'fixation threads' (FTs). The exception is the large genus Chamaecrista in which shrubs and subshrubs house their rhizobial bacteroids more intimately within symbiosomes, whereas large trees have FTs. This study aimed to unravel the evolutionary relationships between Chamaecrista growth habit, habitat, nodule bacteroid type, and rhizobial genotype. The growth habit, bacteroid anatomy, and rhizobial symbionts of 30 nodulated Chamaecrista species native to different biomes in the Brazilian state of Bahia, a major centre of diversity for the genus, was plotted onto an ITS-trnL-F-derived phylogeny of Chamaecrista. The bacteroids from most of the Chamaecrista species examined were enclosed in symbiosomes (SYM-type nodules), but those in arborescent species in the section Apoucouita, at the base of the genus, were enclosed in cell wall material containing homogalacturonan (HG) and cellulose (FT-type nodules). Most symbionts were Bradyrhizobium genotypes grouped according to the growth habits of their hosts, but the tree, C. eitenorum, was nodulated by Paraburkholderia. Chamaecrista has a range of growth habits that allow it to occupy several different biomes and to co-evolve with a wide range of (mainly) bradyrhizobial symbionts. FTs represent a less intimate symbiosis linked with nodulation losses, so the evolution of SYM-type nodules by most Chamaecrista species may have (i) aided the genus-wide retention of nodulation, and (ii) assisted in its rapid speciation and radiation out of the rainforest into more diverse and challenging habitats.

RESUMO

RATIONALE & OBJECTIVE: ß2-Microglobulin (B2M) and ß-trace protein (BTP) are novel endogenous filtration markers that may improve the accuracy of estimated glomerular filtration rate (eGFR) beyond creatinine and cystatin C (eGFRcr-cys), but they have not been assessed in patients with cancer. STUDY DESIGN: Cross-sectional analysis. SETTING & PARTICIPANTS: Prospective cohort of 1,200 patients with active solid tumors recruited between April 2015 and September 2017. EXPOSURE: CKD-EPI equations without race combining B2M and/or BTP with creatinine with or without cystatin C (2-, 3-, or 4-marker panel eGFR). OUTCOME: Performance of equations compared with eGFRcr-cys and non-GFR determinants of serum B2M and BTP (SB2M, and SBTP, respectively). Measured GFR (mGFR) was determined using the plasma clearance of chromium-51 labeled ethylenediamine tetraacetic acid (51Cr-EDTA). ANALYTICAL APPROACH: Bias was defined as the median of the differences between mGFR and eGFR, and 1-P30 was defined as the percentage of estimates that differed by more than 30% from the mGFR (1-P30). Linear regression was used to assess association of clinical and laboratory variables with SB2M, and SBTP after adjustment for mGFR. RESULTS: Mean age and mGFR were 58.8±13.2 SD years and 78.4±21.7 SD mL/min/1.73m2, respectively. Performance of the 3-marker and 4-marker panel equations was better than eGFRcr-cys (lesser bias and 1-P30). Performance of 2-marker panel equations was as good as eGFRcr-cys (lesser bias and similar 1-P30). SB2M and SBTP were not strongly influenced by cancer site. LIMITATIONS: Participants may have had better clinical performance status than the general population of patients with solid tumors. CONCLUSIONS: B2M and BTP can improve the accuracy of eGFR and may be useful as confirmatory tests in patients with solid tumors, either by inclusion in a multimarker panel equation with creatinine and cystatin C, or by substituting for cystatin C in combination with creatinine. PLAIN-LANGUAGE SUMMARY: The most accurate method to assess estimate kidney function is estimated glomerular filtration rate (eGFR) using creatinine and cystatin C (eGFRcr-cys). We studied whether using ß2-microglobulin (B2M) and/or ß-trace protein (BTP) with creatinine with or without cystatin C (2-, 3-, or 4-marker panel eGFR) might be useful in patients with active solid tumors. The performance of the 3-marker and 4-marker panel equations was better than eGFRcr-cys. Performance of 2-marker panel equations was as good as eGFRcr-cys. We conclude that B2M and BTP can improve the accuracy of eGFR and may be useful as a confirmatory test in patients with solid tumors either by inclusion in multimarker panel equation with creatinine and cystatin C or by substituting for cystatin C in combination with creatinine.

RESUMO

Creatinine and cystatin-C are recommended for estimating glomerular filtration rate (eGFR) but accuracy is suboptimal. Here, using untargeted metabolomics data, we sought to identify candidate filtration markers for a new targeted assay using a novel approach based on their maximal joint association with measured GFR (mGFR) and with flexibility to consider their biological properties. We analyzed metabolites measured in seven diverse studies encompasing 2,851 participants on the Metabolon H4 platform that had Pearson correlations with log mGFR and used a stepwise approach to develop models to < -0.5 estimate mGFR with and without inclusion of creatinine that enabled selection of candidate markers. In total, 456 identified metabolites were present in all studies, and 36 had correlations with mGFR < -0.5. A total of 2,225 models were developed that included these metabolites; all with lower root mean square errors and smaller coefficients for demographic variables compared to estimates using untargeted creatinine. Seventeen metabolites were chosen, including 12 new candidate filtration markers. The selected metabolites had strong associations with mGFR and little dependence on demographic factors. Candidate metabolites were identified with maximal joint association with mGFR and minimal dependence on demographic variables across many varied clinical settings. These metabolites are excreted in urine and represent diverse metabolic pathways and tubular handling. Thus, our data can be used to select metabolites for a multi-analyte eGFR determination assay using mass spectrometry that potentially offers better accuracy and is less prone to non-GFR determinants than the current eGFR biomarkers.

RESUMO

ABSTRACT Objective: To understand the experience of young people with orofacial clefts regarding life as an adolescent. Methods: Descriptive, qualitative study, developed in a Brazilian public and tertiary hospital, a reference center in the care of patients with craniofacial anomalies and related syndromes, between February and April 2019. The sample was defined by theoretical saturation. The following inclusion criteria were established: age between ten and 19 years old and having previously operated on orofacial cleft (lip and/or palate). Individuals with fissure associated with syndromes or other malformations were excluded. Data collection was performed through semi-structured interviews, which were audio recorded and transcribed in full. The trigger element was: how has it been for you to experience your adolescence? For the construction of the results, content analysis was used in the thematic modality. Results: Seventeen adolescents participated. From the speeches, three categories were revealed: interacting socially, feeling supported, and experiencing and facing prejudice. Conclusions: The biopsychosocial and conflicting complexity that adolescents with orofacial clefts experience was noticed, as well as the importance of receiving support and establishing modalities of situational coping.

RESUMO

Drug-induced liver injury (DILI) is one of the leading causes of acute liver injury. While many factors may contribute to the susceptibility to DILI, obese patients with hepatic steatosis are particularly prone to suffer DILI. The secretome derived from mesenchymal stem cell has been shown to have hepatoprotective effects in diverse in vitro and in vivo models. In this study, we evaluate whether MSC secretome could improve DILI mediated by amiodarone (AMI) or tamoxifen (TMX). Hepatic HepG2 and HepaRG cells were incubated with AMI or TMX, alone or with the secretome of MSCs obtained from human adipose tissue. These studies demonstrate that coincubation of AMI or TMX with MSC secretome increases cell viability, prevents the activation of apoptosis pathways, and stimulates the expression of priming phase genes, leading to higher proliferation rates. As proof of concept, in a C57BL/6 mouse model of hepatic steatosis and chronic exposure to AMI, the MSC secretome was administered endovenously. In this study, liver injury was significantly attenuated, with a decrease in cell infiltration and stimulation of the regenerative response. The present results indicate that MSC secretome administration has the potential to be an adjunctive cell-free therapy to prevent liver failure derived from DILI caused by TMX or AMI.

RESUMO

We analyzed the European countries participation in clinical trials addressing to new drug development focused on rare diseases in women comparing to more prevalent diseases as breast cancer. Participation was not associated with type of healthcare system neither socio-economic features, but it was associated with population size. Protocol ratios focused on breast cancer vs. orphan drugs and rare diseases was 15:1 and 9:1, respectively, mainly focused on ovarian cancer. Protocol number was insufficient to evaluate the success of Regulation (EC) 141/2000, it is necessary to increase the scientific quality and the number of really new molecules.

RESUMO

The most prevalent cystic fibrosis (CF)-causing mutation - F508del - impairs the folding of CFTR protein, resulting in its defective trafficking and premature degradation. Small molecules termed correctors may rescue F508del-CFTR and therefore constitute promising pharmacotherapies acting on the fundamental cause of the disease. Here, we screened a collection of triazole compounds to identify novel F508del-CFTR correctors. The functional primary screen identified four hit compounds (LSO-18, LSO-24, LSO-28, and LSO-39), which were further validated and demonstrated to rescue F508del-CFTR processing, plasma membrane trafficking, and function. To interrogate their mechanism of action (MoA), we examined their additivity to the clinically approved drugs VX-661 and VX-445, low temperature, and genetic revertants of F508del-CFTR. Rescue of F508del-CFTR processing and function by LSO-18, LSO-24, and LSO-28, but not by LSO-39, was additive to VX-661, whereas LSO-28 and LSO-39, but not LSO-18 nor LSO-24, were additive to VX-445. All compounds under investigation demonstrated additive rescue of F508del-CFTR processing and function to low temperature as well as to rescue by genetic revertants G550E and 4RK. Nevertheless, none of these compounds was able to rescue processing nor function of DD/AA-CFTR, and LSO-39 (similarly to VX-661) exhibited no additivity to genetic revertant R1070W. From these findings, we suggest that LSO-39 (like VX-661) has a putative binding site at the NBD1:ICL4 interface, LSO-18 and LSO-24 seem to share the MoA with VX-445, and LSO-28 appears to act by a different MoA. Altogether, these findings represent an encouraging starting point to further exploit this chemical series for the development of novel CFTR correctors.

RESUMO

Resumo O Subsistema de Atenção à Saúde Indígena (SasiSUS), como parte do Sistema Único de Saúde (SUS), é responsável pela atenção à saúde dos povos indígenas do Brasil. Em âmbito local, são os Distritos Sanitários Especiais Indígenas (DSEI) os responsáveis pela gestão, planejamento e organização do processo de trabalho das equipes multidisciplinares de saúde indígena (EMSI), que realizam a atenção primária à saúde para essa população. O objetivo do estudo foi analisar como ocorrem o planejamento e a gestão do processo de trabalho das EMSI. Foi realizado um estudo de casos múltiplos holístico, considerando sete DSEI como unidades de análise. A principal fonte de dados utilizada foi a entrevista e, de forma complementar, a observação direta. Os resultados indicaram que, de forma geral, o planejamento está presente na organização do processo de trabalho das equipes, com variações entre os DSEI. A efetivação das ações planejadas foi relacionada à disponibilidade de diferentes recursos: funcionamento adequado do sistema de informação e a articulação intra e intersetorial do SasiSUS. Como conclusão, apontou-se a necessidade de radicalização da participação no planejamento e na gestão, necessária a uma ação coordenada para garantia da atenção diferenciada e dos princípios do SUS.


Abstract The Indigenous Health Care Subsystem (SasiSUS), as part of the Brazilian National Health System (SUS), is responsible for health care for indigenous peoples in Brazil. At the local level, the Special Indigenous Health Districts (DSEI) are responsible for managing, planning, and organizing the work process of the multidisciplinary indigenous health teams (EMSI), which provide primary health care for this population. The objective of the study was to analyze how the planning and the management of the EMSI work process occurs. A holistic multiple-case study was carried out, considering seven DSEI as units of analysis. The main source of data used were interviews and, in a complementary way, direct observation. The results indicated that, in general, planning is present in the organization of the teams' work process, with variations between the DSEI. Carrying out the planned actions was related to the availability of different resources: adequate functioning of the information system and the intra and intersectoral articulation of SasiSUS. As a conclusion, the need to radicalize participation in planning and management, necessary for a coordinated action to guarantee differentiated care and the principles of SUS, was pointed out.

RESUMO

ABSTRACT Objective: To understand the experience of parents regarding prenatal diagnosis of orofacial cleft in their children. Methods: Descriptive study with a qualitative approach, carried out in a Brazilian public tertiary hospital between January and March 2019. Parents who were accompanying their children during hospitalization for primary surgeries and who had received the diagnosis of malformation during pregnancy were included in this study. Data was collected through semi-structured interviews, which were audio-recorded and transcribed in full. To prepare the results, Content Analysis was used in the Thematic modality. Results: The sample had 17 participants: 16 mothers and one father. From the speeches, three categories were unveiled: dealing with the unknown, assimilating the diagnosis, and positive and negative implications of prenatal diagnosis. Conclusions: We learned how complex and conflicting it was for parents to receive the diagnosis of malformation in their children, and that family and professional support was essential to the process of assimilation and coping. The findings point to the need for planning and implementing interventions, protocols and/or public policies aimed at assisting these parents in this period.

RESUMO

Inflammatory bowel disease (IBD), including ulcerative colitis (UC) and Crohn disease (CD), has emerged as a global disease with an increasing incidence in developing and newly industrialized regions such as South America. This global rise offers the opportunity to explore the differences and similarities in disease presentation and outcomes across different genetic backgrounds and geographic locations. Our study includes 265 IBD patients. We performed an exploratory analysis of the databases of Chilean and North American IBD patients to compare the clinical phenotypes between the cohorts. We employed an unsupervised machine-learning approach using principal component analysis, uniform manifold approximation, and projection, among others, for each disease. Finally, we predicted the cohort (North American vs Chilean) using a random forest. Several unsupervised machine learning methods have separated the 2 main groups, supporting the differences between North American and Chilean patients with each disease. The variables that explained the loadings of the clinical metadata on the principal components were related to the therapies and disease extension/location at diagnosis. Our random forest models were trained for cohort classification based on clinical characteristics, obtaining high accuracy (0.86 = UC; 0.79 = CD). Similarly, variables related to therapy and disease extension/location had a high Gini index. Similarly, univariate analysis showed a later CD age at diagnosis in Chilean IBD patients (37 vs 24; P = .005). Our study suggests a clinical difference between North American and Chilean IBD patients: later CD age at diagnosis with a predominantly less aggressive phenotype (39% vs 54% B1) and more limited disease, despite fewer biological therapies being used in Chile for both diseases.

RESUMO

Current guidelines recommend estimating glomerular filtration rate (eGFR) using creatinine (eGFRcr) with the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equation as the first test for GFR evaluation, but the Cockcroft-Gault (CG) equation is still commonly used in oncology practice and clinical trials despite increasing evidence of its inaccuracy compared to measured GFR (mGFR). Guidelines recommend eGFR using cystatin C (eGFRcys) or both markers (eGFRcr-cys) as a confirmatory test, but neither was carefully evaluated in cancer patients. Therefore, we compared performance of the CKD-EPI equations and others to the CG equation in adults with a variety of solid tumors. The mGFR was determined by plasma clearance of 51Cr-EDTA. Bias was defined as the median of the differences between mGFR and eGFR while accuracy was defined as the percentage of estimates that differed by more than 30% from the measured GFR (1-P30). We prospectively recruited 1,200 patients between April 2015 and September 2017 with a mean age and mGFR of 58.8 years and 78.4 ml/min/1.73m2, respectively. Bias among eGFRcr equations varied from -8.1 to +6.1 ml/min/1.73 m2. CG was the least accurate, 1-P30 (95% confidence interval) was 24.9 (22.4- 27.3)%; CKD-EPI had 1-P30 of 19.1 (16.8-21.2)% while eGFRcr-cys had the best performance: bias -2.0 (-2.6 to -1.1) ml/min/1.73m2 and 1-P30 7.8 (6.3-9.4)%. Thus, the CG equation should not be preferred over CKD-EPI equation, and eGFRcr-cys can be used as a confirmatory test in adults with solid tumors. Hence, a major policy implication would be to adopt general practice guideline-recommended methods for GFR evaluation in oncology practice and clinical trials.

RESUMO

O objetivo do artigo é apresentar os resultados do estudo de avaliabilidade do Sistema de Informação da Atenção à Saúde Indígena (SIASI) e suas implicações para a gestão em saúde no nível local. O estudo foi desenvolvido com base nas seguintes etapas: descrição da intervenção, descrição dos usuários potenciais e análise de contexto (interno e externo). Para tanto, adotaram-se as seguintes técnicas de coleta de dados: análise documental, entrevistas com informantes-chave e oficina de trabalho. A modelização do SIASI no Distrito Sanitário Especial Indígena (DSEI) Alto Rio Solimões (Amazonas) e no DSEI Leste Roraima (Roraima) possibilitou a visualização esquemática do modo de funcionamento do sistema, considerando-se as peculiaridades do fluxo de informação descentralizado e centralizado. A análise de contexto aponta para o reconhecimento do SIASI como ferramenta para a organização do processo de trabalho das equipes multidisciplinares de saúde indígena (EMSI) e o acompanhamento da situação de saúde, ainda que ocorra baixa utilização das informações nos territórios. Entre os desafios, persistem os problemas de infraestrutura e a fragmentação das informações, provocando aumento do retrabalho na alimentação dos dados. Como potencialidade, destaca-se a criação do Painel SIASI Local, que gera relatórios dinâmicos e interativos sobre a situação de saúde. Conclui-se que a capacidade de utilização do SIASI como ferramenta de apoio à gestão pelo nível local pode ser potencializada com a ampliação do processo de descentralização do fluxo de informações.


The article's objective is to present the results of the study on the evaluability of the Information System on Indigenous Health (SIASI) and its implications for local health administration. The study was performed with the following stages: description of the intervention, description of potential users, and context analysis (internal and external). The following data collection techniques were adopted: document analysis, interviews with key informants, and a workshop. Modeling of the SIASI in the Special Indigenous Health District Upper Solimões River (Amazonas State) and Special Indigenous Health District Eastern Roraima (Roraima State) allowed a schematic view of the system's mode of functioning, considering the peculiarities of the decentralized and centralized information flow. Context analysis pointed to acknowledgment of the SIASI as a tool for organization of the work process in the multidisciplinary indigenous health team (EMSI) and for follow-up of the health situation, despite low utilization of the information in the territories. Persistent challenges include infrastructure problems and fragmentation of information, causing an increase in rework in feeding the data. One key feature is the creation of the Local SIASI Panel, generating dynamic and interactive reports on the health situation. In conclusion, the capacity for use of the SIASI as a tool to support local management can be enhanced by expanding the decentralization of the information flow.

El análisis de contexto apunta al reconocimiento del SIASI como herramienta para la organización del proceso de trabajo de los equipos multidisciplinares de salud indígena (EMSI) y el seguimiento de la situación de salud, aunque exista una baja utilización de la información en los territorios. Entre los desafíos persisten los problemas de infraestructura y fragmentación de la información, provocando un aumento del retrabajo en la alimentación de datos. Como potencialidad se destaca la creación del Panel SIASI Local que genera informes dinámicos e interactivos sobre la situación de salud. Se concluye que la capacidad de utilización del SIASI como herramienta de apoyo a la gestión por parte del nivel local puede potenciarse con la ampliación del proceso de descentralización del flujo de información.
