SUMMARY INTRODUCTION: Chronic kidney disease has presented frequencies that exceed the installed capacity of dialysis services, and data on prevalence are uncertain worldwide. OBJECTIVE: The objective of this study was to analyze the epidemiological profile of patients assisted in renal replacement therapy and details on the assistance provided. METHODS: Population-based cross-sectional study with information obtained from the Unified Health System database. The research location was the state of Paraíba, and the observation period was from January 1, 2009, to December 31, 2013, n = 64,676 documents, and the variables observed were: gender; age group, race, or color; place of residence; place where the therapy was performed; vascular access; modality if hemodialysisor peritoneal dialysis; registration on the kidney transplantation list; infection by hepatitis B, C, and HIV viruses; and costs. RESULTS: A higher prevalence of request for highly complex procedure was observed in males (56.8%) and white (39%). The cities with the highest prevalence of dialysis patients were João Pessoa, Campina Grande, Santa Rita, Sousa, Bayeux, and Patos. Most of the sample referred to patients undergoing hemodialysis as a renal replacement therapy modality, with 42.2% not having definitive arteriovenous fistula access. The renal replacement therapy expenses observed were increasing, and in 2009, they accounted for 2.89% of health spending, reaching 3.32% of state health spending in 2013. CONCLUSION: Using secondary data from DATASUS to understand the population with chronic kidney disease and the assistance offered is possible.

SUMMARY OBJECTIVE: The aim of this study was to evaluate serum 25(OH)D concentrations in the homebound elderly people and relate them to level of dementia, nutritional risk, and route of dietary administration. METHODS: This is a cross-sectional study involving 207 bedridden elderly people assisted by the Home Care Service in the city of Santo André – SP, from June to December 2016. The following factors were evaluated: dietary intake of vitamin D, arm circumference, triceps skin fold thickness, calf circumference, nutritional risk by Mini-Nutritional Assessment, level of dementia by the adapted Clinical Dementia Rating questionnaire, and laboratory tests such as serum concentrations of 25(OH)D, ultrasensitive C-reactive protein, alkaline phosphatase, serum calcium, and parathormone. RESULTS: The mean age of the elderly people was 81.6 (9.2) years. Deficiency of 25(OH)D was observed in 76.3% of the elderly people. There was an inverse correlation between serum concentrations of 25(OH)D: parathormone (r=-0.418, p<0.001) and alkaline phosphatase (r=-0.188, p=0.006) and a direct correlation with serum calcium (r=-0.158, p=0.022). Logistic regression showed that vitamin D deficiency was directly and independently associated with oral feeding (odds ratio 7.71; 95%CI 2.91–20.40). CONCLUSION: Bedridden households showed high prevalence of vitamin D deficiency without association with nutritional risk and level of dementia. Oral diet was associated with vitamin D deficiency, possibly due to low consumption of source foods.

ABSTRACT OBJECTIVE To compare the incidence of covid-19 symptoms between informal home-based workers and a control group and to assess the association of these cases with blood elements concentrations and other relevant risk factors for Sars-Cov-2 infection. METHODS Welders chemically exposed to potentially toxic elements (PTEs) (n = 26) and control participants (n = 25) answered questionnaires on adherence to social distancing and signs and symptoms of the disease for five months during the covid-19 pandemic. After follow-up, covid-19 serology tests were performed on a subsample of 12 chemically exposed workers and 20 control participants. Before the pandemic, PTE concentrations in blood (As, Mn, Ni, Cd, Hg, Sb, Sn, Cu, Zn, and Pb) were measured by ICP-MS. RESULTS The chemically exposed group had higher lead and cadmium levels in blood (p < 0.01). The control group presented lower adherence to social distancing (p = 0.016). Although not significant, welders had a 74% greater chance of having at least one covid-19 symptom compared with control participants, but their adherence to social distancing decreased this chance by 20%. The use of taxis for transportation was a risk factor significantly associated with covid-19 symptoms. CONCLUSION The lower adherence to social distancing among the control group greatly influences the development of covid-19. The literature lacks data linking exposure to PTEs and Sars-Cov-2 infection and/or severity. In this study, despite chemical exposure, working from home may have protected welders against covid-19, considering that they maintained greater social distancing than control participants. covid19 covid 19 covid-1 homebased based SarsCov2 SarsCov Sars Cov 2 Sars-Cov- (PTEs n 26 25 pandemic followup, followup follow up, up follow-up 1 As, As (As Mn Ni Cd Hg Sb Sn Cu Zn Pb ICPMS.

ABSTRACT Objective To evaluate the effects of the Covid-19 pandemic on the profile of emergency eye-related visits and compare the findings with the same period before the pandemic. Methods Cross-sectional study performed during one year at a reference eye hospital. Cases registered at the emergency Municipal Hospital Complex of Santo Andre, Brazil, between March, 2019 and February, 2020 were included in the study as the Pre-pandemic group. Cases registered between March, 2020 and February, 2021 were included as the Pandemic group. Cases were classified according to the International Classification of Diseases ICD-10 and Related Health Problems. Results There was a decrease of 52.1% in the emergency eye care visits during the pandemic period (n=9,198) when compared to the pre-pandemic period (n=19,220), with significant reductions in nonspecific cases (-98.1%), postoperative visits (-67.0%), disorders of the conjunctiva (-54.1%), tear film (-49.4%) and refraction (-85.6%) during the pandemic period. Conditions such as retina disorders (+202.7%), sclera disorders (+76.2%), orbit disorders (+20.2%), glaucoma (+66.6%) and trauma (+19.4%) have shown increased rates, as well as those related to eyelids (+186.9%), cornea (+33.4%), uvea (+40.2%), and herpes (+55.3%). Conclusion A drastic reduction in the number of eye-related emergency visits was observed during the Covid-19 pandemic, outlining a new profile of care, with higher frequency of sight-threatening conditions and lower frequency of contagious and non-specific diagnosis.

SUMMARY OBJECTIVE: Due to the speed of development observed in breast cancer, several studies aimed at discovering new biomarkers have been carried out in order to arrive at an early diagnosis. As survivin plays a fundamental role in the evasion of apoptosis in tumor cells, the aim of this study was to verify the expression profile of the survivin gene in paraffin-embedded breast tumor samples and associate it with the clinical characteristics of the patients. METHODS: This is a cross-sectional study, for which 100 tumor samples were obtained from cancer patients treated throughout the year 2019 at Instituto de Mama do Cariri (Juazeiro do Norte, in the state of Ceará). This study included women over 30 years old who had confirmed breast cancer through anatomopathological examination but excluded those with non-neoplastic breast comorbidities, other neoplasms, or chronic diseases. Survivin gene expression was assessed by quantitative polymerase chain reaction. RESULTS: The expression of survivin is associated with the lack of expression of estrogen (p=0.027) and progesterone (p>0.0005) receptors. It means that survivin expression is higher in patients in which labeling was absent for estrogen receptor and progesterone receptor. CONCLUSION: Our data reinforce that survivin expression is higher in estrogen receptor-patients, thus representing an additional prognostic tool.

SUMMARY OBJECTIVE: The aim of this study was to investigate the role of irisin in type 2 diabetes mellitus and its association with metabolic alterations and obesity. METHODS: A cross-sectional case-control study was conducted on participants treated at Centro Universitário FMABC between August 2018 and July 2019, by comparing a control group (n=14) with type 2 diabetes mellitus patients (n=16). The control group consisted of participants aged above 21 years with no chronic diseases, diabetes, smoking, or illicit drug use. The type 2 diabetes mellitus group included patients aged above 21 years, who were diagnosed with type 2 diabetes for at least 5 years (glycated hemoglobin>7%). Exclusion criteria were not willing to continue, recent hospitalization, and failure to meet inclusion criteria. Biochemical parameters included blood glucose, glycated hemoglobin, plasma irisin levels, and irisin gene expression in peripheral blood. RESULTS: Type 2 diabetes mellitus patients exhibited significantly higher plasma glucose levels [143 (40) vs. 92 (13) mg/dL, *p<0.05] and glycated hemoglobin levels [7.1% (1.6) vs. 5.6% (0.5), *p<0.05] compared to the control group. Irisin gene expression in type 2 diabetes mellitus patients was lower 0.02288 (0.08050) than the control group 8.506e-006 (1.412e-005) (p=0.06). Correlation analysis revealed a positive association between irisin expression and body mass index in type 2 diabetes mellitus (Rho=0.5221, 95%CI -0.058 to 0.838, p=0.06), while plasma irisin showed a negative correlation with body mass index (Rho=-0.656, 95%CI -0.836 to 0.215, p=0.03). No significant correlations were found between plasma glucose or glycated hemoglobin levels and irisin expression. CONCLUSION: The data suggests that body mass index directly influences plasma irisin levels and the regulation of irisin gene expression, possibly linking irisin to adiposity changes observed in obesity-related type 2 diabetes mellitus.

ABSTRACT Objective To compare serum amyloid A concentrations between overweight and eutrophic children and adolescents and to relate it to lipid profiles, glucose tolerance, and carotid intima-media thickness. Methods One hundred children and adolescents (mean age: 10.8±3.16 years) were included and divided into two groups: overweight and non-overweight. The following were evaluated: Z-score body mass index, carotid intima-media thickness, lipid metabolism biomarkers (lipid profile and apolipoproteins A1 and B), inflammatory biomarkers (ultra-sensitive C-reactive protein and serum amyloid A), and glucose homeostasis model assessment of insulin resistance. Results The groups were homogeneous in age, sex, and pubertal stage. Higher levels of triglycerides, apolipoprotein B, homeostasis model assessment of insulin resistance, ultrasensitive C-reactive protein, serum amyloid A, and carotid intima-media thickness were observed in the overweight group. In the multivariate analysis, age (OR=1.73; 95%CI: 1.16-2.60, p=0.007), Z-score body mass index (OR=3.76; 95%CI: 1.64-8.59, p=0.002), apolipoprotein-B (OR=1.1; 95%CI: 1.01-1.2, p=0.030), and carotid intima-media thickness (OR=5.00; 95%CI: 1.38-18.04, p=0.014) were independently associated with serum amyloid A levels above the fourth quartile of the studied sample (>9.4mg/dL). Conclusion Overweight children and adolescents had higher serum amyloid A concentrations than eutrophic children. There was an independent association between higher concentrations of serum amyloid A and Z-score, body mass index, apolipoprotein B, and carotid intima-media thickness, indicating the importance of this inflammatory biomarker in identifying the early risk of atherosclerosis. profiles tolerance intimamedia intima media mean 108316 10 8 3 16 10.8±3.1 years nonoverweight. nonoverweight non overweight. non-overweight evaluated Zscore Z score B , B) ultra sensitive Creactive C reactive A) resistance sex stage triglycerides group analysis OR=1.73 OR173 OR 1 73 (OR=1.73 95%CI 95CI CI 95 1.162.60, 116260 1.16 2.60, 2 60 1.16-2.60 p=0.007, p0007 p p=0.007 0 007 p=0.007) OR=3.76 OR376 76 (OR=3.76 1.648.59, 164859 1.64 8.59, 64 59 1.64-8.59 p=0.002, p0002 p=0.002 002 p=0.002) apolipoproteinB OR=1.1 OR11 (OR=1.1 1.011.2, 10112 1.01 1.2, 01 1.01-1.2 p=0.030, p0030 p=0.030 030 p=0.030) OR=5.00 OR500 5 00 (OR=5.00 1.3818.04, 1381804 1.38 18.04, 38 18 04 1.38-18.04 p=0.014 p0014 014 >9.4mg/dL. 94mgdL mgdL >9.4mg/dL . 9 4mg dL mg (>9.4mg/dL) Zscore, score, atherosclerosis 10831 10.8±3.

ABSTRACT OBJECTIVE To compare the incidence of covid-19 symptoms between informal home-based workers and a control group and to assess the association of these cases with blood elements concentrations and other relevant risk factors for Sars-Cov-2 infection. METHODS Welders chemically exposed to potentially toxic elements (PTEs) (n = 26) and control participants (n = 25) answered questionnaires on adherence to social distancing and signs and symptoms of the disease for five months during the covid-19 pandemic. After follow-up, covid-19 serology tests were performed on a subsample of 12 chemically exposed workers and 20 control participants. Before the pandemic, PTE concentrations in blood (As, Mn, Ni, Cd, Hg, Sb, Sn, Cu, Zn, and Pb) were measured by ICP-MS. RESULTS The chemically exposed group had higher lead and cadmium levels in blood (p < 0.01). The control group presented lower adherence to social distancing (p = 0.016). Although not significant, welders had a 74% greater chance of having at least one covid-19 symptom compared with control participants, but their adherence to social distancing decreased this chance by 20%. The use of taxis for transportation was a risk factor significantly associated with covid-19 symptoms. CONCLUSION The lower adherence to social distancing among the control group greatly influences the development of covid-19. The literature lacks data linking exposure to PTEs and Sars-Cov-2 infection and/or severity. In this study, despite chemical exposure, working from home may have protected welders against covid-19, considering that they maintained greater social distancing than control participants.

Abstract Objective: The nutritional status resultant from dietary habits along with socioeconomic conditions and the school environment are directly related to the individual's health condition not only in their childhood but also throughout adulthood. The aim of this study was to evaluate the effects of socioeconomic factors on the anthropometric profile and to analyze a probable association between this profile and biochemical markers in children attending public daycare centers. Methods: It is a transversal study developed in a probability sample of clusters of children from 6 months to 5 years old. Anthropometric and socioeconomic data were gathered at the CMEIs, questionnaires on the nutritional status were applied and blood was collected at the Family Health Units (USFs). Results: Female children are three times more likely to be underweight; in families with five members, it is 1/3 more likely that children of higher-educated parents are overweight. Among the results of the biochemical tests, hypervitaminosis A was a relevant aspect, positively correlating with copper (p=0.005) and zinc (p=0.008). Conclusion: Therefore, since the influence of the family is an important predictor of overweight and its future outcomes related to nutritional deficiencies and inadequate dietary intake, educational interventions are vital as a way to pave the path to prevention.

SUMMARY OBJECTIVE: The aim of this study was to assess the quality of primary health care services through self-reports by caregivers of children and adolescents living in quilombola communities in Brazil. METHODS: This is a cross-sectional study in accordance with the STROBE (STrengthening the Reporting of OBservational studies in Epidemiology). Exposure variables included sociodemographic characteristics; and outcome variable was the quality of primary health care offered to quilombola children and adolescents. RESULTS: A total of 68 individuals participated in the survey. Quilombolas have a low income, a lower level of education, do not work, and receive government benefits. Our results showed that the quality of primary health care, measured by the experience of caregivers of quilombola children and adolescents, generally presents satisfactory values. CONCLUSION: The quality of primary health care has generally satisfactory values. However, as these results differ from most studies, more research should be conducted.

RESUMO O câncer de pulmão é o primeiro em incidência e mortalidade, sendo responsável mundialmente por cerca de 1,8 milhão de mortes. No Brasil, 31.270 casos novos foram diagnosticados em 2018, sendo 18.740 em homens e 12.350 em mulheres. Um dos principais desafios do câncer de pulmão é o diagnóstico precoce, na maioria das vezes a doença é detectada em fases tardias, o que implica em mau prognóstico. Os biomarcadores tumorais são extremamente relevantes no diagnóstico precoce, compreensão da carcinogênese, determinação do prognóstico e escolha terapêutica. O presente trabalho revisa biomarcadores de câncer de pulmão de células não pequenas descritos na literatura e suas aplicações diagnósticas, prognósticas e terapêuticas, intervenção e controle terapêutico para terapia individualizada. Embora ainda exista um vasto universo a ser explorado, estudos revelam um futuro promissor para o tratamento do câncer de pulmão com terapias cada vez mais personalizadas e assertivas que aumentam as chances de sobrevida livre de progressão.

ABSTRACT Lung cancer is the first in terms of incidence and mortality, being responsible worldwide for about 1.8 million deaths. In Brazil 31,270 new cases were diagnosed in 2018, 18,740 in men and 12,350 in women. One of the main challenges about lung cancer is performing an early diagnosis, in most cases the disease is detected in the late stages, which implies in poor prognoses. Tumor biomarkers are hugely relevant in early diagnosis, understanding of carcinogenesis, prognostic determination and therapeutic choice. The present paper reviews non-small cell lung cancer biomarkers described in the literature and their diagnostic, prognostic and therapeutic applications, intervention and therapeutic control for individualized therapy. Although there is still a vast universe to be explored, studies reveal a promising future for lung cancer treatment with increasingly personalized and assertive therapies that increase the chances of progression-free survival.

RESUMO A vigilância da qualidade dos esgotos sanitários pode representar uma ferramenta complementar para monitoramento de doenças infecciosas e prevenção de surtos epidêmicos, especialmente quando a capacidade para testes clínicos é limitada. Dessa maneira, o presente estudo descreve o detalhamento técnico de um método de baixo custo para a concentração e extração de ácidos nucleicos de amostras de esgoto sanitário como etapa prévia para a detecção de vírus e outros agentes patogênicos. Para validar a metodologia proposta, após as etapas de concentração e extração, analisaram-se a presença do ácido ribonucleico do SARS-CoV-2 (COVID-19) nas amostras, por meio de reação em cadeia da polimerase em tempo real. O ácido ribonucleico do vírus foi detectado em 80% das amostras de esgoto sanitário analisadas, comprovando o êxito do procedimento metodológico adotado. A detecção precoce de um patógeno associado ao trabalho de equipes multidisciplinares possibilita a prática da vigilância epidemiológica, que auxilia na tomada de decisões na Saúde Única — união indissociável entre a saúde animal, humana e ambiental.

ABSTRACT Sewage quality surveillance can represent a complementary tool for monitoring infectious diseases and preventing epidemic outbreaks, especially when the capacity for clinical testing is limited. Thus, the present study describes the technical details of a low-cost method for concentrating and extracting nucleic acids from sewage samples, as a preliminary step for the detection of viruses and other pathogens. To validate the proposed methodology, after the concentration and extraction steps, the presence of the SARS coronavirus-2 (COVID-19) in the samples was analyzed using real-time polymerase chain reaction. The virus’ ribonucleic acid was detected in 80% of the sewage samples analyzed, proving the success of the methodological procedure adopted. The early detection of a pathogen associated with the work of multidisciplinary teams allows the practice of epidemiological surveillance, which assists in making decisions about One Health — an inseparable union between animal, human, and environmental health.

RESUMO OBJETIVO: Caracterizar os efeitos da aspiração nasal com Proetz® no pico do fluxo inspiratório nasal (Pnif) em pacientes com sinusite pediátrica (SP) com obstrução nasal. MÉTODOS: Trata-se de um ensaio clínico analítico descritivo, não randomizado, com abordagem quantitativa. A amostra foi composta por 30 crianças. Inicialmente, o Pnif foi medido e a escala visual analógica (EVA) foi utilizada para obstrução nasal, seguida do procedimento de aspiração nasal. O questionário Snot-22 foi aplicado ao responsável legal de cada criança e, uma semana depois, foi reaplicado para fins de acompanhamento. RESULTADOS: Dezesseis (53,3%) pacientes eram do sexo feminino e 14 (46,7%) do sexo masculino, com idade média de 6,4±1,8 anos (entre 4 e 10 anos). A análise da EVA para obstrução antes da intervenção revelou que dez dos participantes (33,3%) apresentaram níveis moderados e 20 deles (66,7%), níveis graves. No entanto, após a aplicação do método Proetz®, todas as amostras (n=30) apresentaram níveis leves. O Pnif aumentou significativamente após a utilização da técnica, com uma melhoria de 23,4% nos valores médios. Não houve correlação significativa entre EVA e Pnif. CONCLUSÃO: A aspiração nasal com o método Proetz® melhorou significativamente o quadro clínico de pacientes com sinusite com obstrução nasal, de acordo com a escala visual analógica, o Pnif e o questionário Snot-22. Não foi encontrada correlação entre EVA e Pnif. O estudo confirma a importância de intervenções não farmacológicas no tratamento da sinusite em crianças, resultando em melhoria na sua qualidade de vida.

SUMMARY OBJECTIVE: To characterize the effects of nasal aspiration with Proetz® in peak nasal inspiratory flow (PNIF) in pediatric sinusitis (PS) patients with nasal obstruction. METHODS: This is a non-randomized descriptive-analytical clinical trial with a quantitative approach. The sample comprised 30 children. Initially, the PNIF was measured and the Visual Analogical Scale (VAS) was used for nasal obstruction, followed by the nasal aspiration procedure. The SNOT-22 questionnaire was applied to the legal guardian of each child, and one week later, it was reapplied for the sake of follow-up. RESULTS: 16 (53.3%) patients were females and 14 (46.7%) were males, with an average age of 6.4±1.8 years (between 4 and 10 years of age). Analyses of the VAS for obstruction before the intervention revealed that 10 of the participants (33.3%) presented moderate levels, and 20 of them (66.7%) severe levels. However, after the Proetz® method was applied, all the samples (n=30) had mild levels. The PNIF significantly increased after the technique was used, with an improvement of 23.4% in mean values. There was no significant correlation between the VAS and the PNIF. CONCLUSION: Nasal aspiration with the Proetz® method significantly improved the clinical condition of sinusitis patients with nasal obstruction according to the visual analogical scale, the PNIF, and the SNOT-22 questionnaire. No correlation between the VAS and the PNIF could be found. The study confirms the importance of non-pharmacological interventions in the treatment of sinusitis in children, thus resulting in an improvement in their quality of life.
