Abstract
The use of the brine shrimp Artemia salina (Leach) in acute toxicity assays has great potential due to its simplicity, low cost and reproducibility. In the current study, some of the variables that can influence the reliability of the assay in terms of test organism survival, were evaluated as part of its implementation in our laboratory. The quality and type of water used, the buffer components and other parameters (salinity, pH and dissolved oxygen level), were all evaluated for optimisation purposes. DMSO (dimethyl sulphoxide) was used as the test substance in the toxicity assay, to evaluate the concentration limits as a solvent in sample preparation. Regarding the buffer salinity, pH and dissolved oxygen level, we found that a 25% to 30% deviation from the standard values did not affect the survival of the nauplii (the first-instar larval stage) under assay conditions. In summary, we corroborate the potential use of this model for the prediction of the toxic potential of substances, to inform future testing strategies.

Abstract
Duchenne muscular dystrophy (DMD) occurs due to genetic mutations that lead to a deficiency in dystrophin production and consequent progressive degeneration of skeletal muscle fibres, through oxidative stress and an exacerbated inflammatory process. The flavonoid trilobatin (TLB) demonstrates antioxidant and anti-inflammatory potential. Its high safety profile and effective action make it a potent therapy for the process of dystrophic muscle myonecrosis. Thus, we sought to investigate the action of TLB on damage in a DMD model, the mdx mouse. Eight-week-old male animals were treated with 160 mg/kg/day of trilobatin for 8 weeks. Control animals were treated with saline. Following treatment, muscle strength, serum creatine kinase (CK) levels, histopathology (necrotic myofibres, regenerated fibres/central nuclei, Feret's diameter and inflammatory area) and the levels of catalase and NF-κB (western blotting) of the quadriceps (QUA), diaphragm (DIA) and tibialis anterior (TA) muscles were measured. TLB was able to significantly increase muscle strength and reduce serum CK levels in dystrophic animals. The QUA of mdx mice showed a reduction in catalase and the number of fibres with a centralized nucleus after treatment with TLB. In the DIA of dystrophic animals, TLB reduced the necrotic myofibres, inflammatory area and NF-κB and increased the number of regenerated fibres and the total fibre diameter. In TA, TLB increased the number of regenerated fibres and reduced catalase levels in these animals. It is concluded that in the mdx experimental model, treatment with TLB was beneficial in the treatment of DMD.

Abstract
INTRODUCTION Zerumbone is a natural compound found in bitter ginger plants (Zingiber zerumbet) that shows antiproliferative, antioxidant, anti-inflammatory, and analgesic properties. We aimed to investigate the role of zerumbone in improving the quality of life and symptom control in cancer patients with no treatment options. METHODS We conducted a pilot, non-randomized, single-center, open prospective, and systematic study on the use of 400 mg of zerumbone twice a day. RESULTS The study included 35 patients (mean age, 68 years; 64% men), of which 16 completed the eight-week study. The intention-to-treat population showed no significant changes in weight or sleep quality over the eight-week study. Assessments performed using the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 (EORTC QLQ-C30) showed significant improvements in the quality of life in the global (p = 0.072), activity (p = 0.0393), social (p = 0.0001), and emotional (p = 0.0023) dimensions. The Hospital Anxiety and Depression Scale (HADS) questionnaire scores showed significant improvement in anxiety (p = 0.032) and depression (p = 0.021), while the Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F) questionnaire scores also indicated a significant improvement (p = 0.001). Bitter ginger showed low toxicity. CONCLUSIONS Bitter ginger showed promising results in improving the quality of life and reducing symptoms of anxiety and depression in the study population. A randomized placebo-controlled study is necessary to confirm these results. This trial was registered under the number FMABC: CAAE - 93459418.00000082, at ISRCTN (BIOMED CENTRAL) NUMBER 4388 (03/07/23) and at Plataforma Brasil (https://plataformabrasil.saude.gov.br/login.jsf).

Abstract
BACKGROUND Atopic dermatitis (AD) is a relapsing, chronic cutaneous inflammatory disease with onset, in general, in early childhood. Chronic skin inflammation is associated with overproduction of reactive oxygen species (ROS) such as superoxide and hydrogen peroxide. Oxidative stress, an imbalance between the production of free radicals and antioxidant defense, results in tissue inflammation due to the upregulation of genes that encode inflammatory cytokines. This condition plays an important role in the pathogenesis of AD. OBJECTIVE To compare the antioxidant defense in children and adolescents with AD with that of healthy individuals and to verify the association of antioxidant defense with disease severity and nutritional status. METHODS Cross-sectional study that evaluated 48 children and adolescents with AD and 25 controls for nutritional assessment (body mass index z score [BMIZ] and height for age z score [HAZ]) and levels of vitamins A, C, E, and D, zinc (Zn), copper (Cu), antioxidant enzymes (superoxide dismutase [SOD], catalase [CAT], glutathione peroxidase [GPx]), high-sensitivity C-reactive protein (CRP) and interleukin 33 (IL-33). RESULTS There was no significant difference in the comparison between AD and control groups for serum levels of vitamins (A, D, C, and E), copper, and antioxidant enzymes. Serum zinc levels were higher in the AD group (β = 24.20; 95% CI 13.95-34.91; P < 0.001) even after adjusting the BMIZ, HAZ, gender, IL-33, and CRP. Children and adolescents with moderate or severe AD compared to mild AD (SCORAD - 36.7±17.4 vs 11.8 ± 3.9; P < 0.001) had lower values of the vitamin E/total lipid ratio (3.68 [0.29;12.63] vs 5.92 [3.27;17.37]; P = 0.013). CONCLUSION Children and adolescents with AD had higher concentrations OF elevated levels of zinc compared to controls, a fact not observed for other biomarkers of antioxidant defense. AD in moderate or severe forms presented lower concentrations of vitamin E, a potent antioxidant fat soluble.

Abstract
The Pipercubeba, it is one spice, widely consumed in Europe, which has several bioactive molecules, between those a lignan named cubebin. Cubebin has several known biological activities, such as analgesic activity and anti-inflammatory, trypanocidal activity, leishmanicidal and antitumor activity. The objective of this study was to evaluate the antiproliferative activity "in vitro" cubebin in eight different human tumor cell lines. It was fully characterized by IR analysis, NMR, mass spectrometry, DSC, TGA, residual solvent and elemental analysis. The antitumor activity of cubebin was evaluated "in vitro" on eight different human tumor cell lineages. Cubebin showed GI50≤30μg/mL for lineage cell U251 (glioma CNS), 786-0 (kidney), PC-3 (prostate), HT-29 (colon rectum). For K562 cells (leukemia), cubebin presented GI50≤to 4.0mg/mL. For the other lineages cells, MCF-7 (breast) and NCI-H460 to cubebin can be considered inactive because of GI50>250mg/mL. Analyzing the selectivity index for cubebin, it can be observed that high selectivity of cubebin to K562 lineage cells (leukemia). Analyzing the cytotoxic potential of cubebin was observed that probably acts cubebin altering metabolism, inhibiting cell growth - a cytostatic effect, showing no cytocidal effect on any lineage cell.

Abstract
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
Hyperglycemia leads to microvascular lesions in various tissues. In diabetic nephropathy-DN, alterations in usual markers reflect an already installed disease. The study of new biomarkers for the early detection of diabetic complications can bring new prevention perspectives. Rats were divided into diabetic adult-DMA-or elderly-DME and control sham adult-CSA-or control sham elderly-CSE. Blood and urine samples were collected for biochemical analysis. Bulbar region, cardiac, hepatic and renal tissues were collected for target gene expression studies. As result, DMA showed decreased TNFR1, MCT1 and CD147 expression in the bulbar region, TNFR1 in the heart, VEGFA and CD147 in the kidney and TNFR1 in blood. Positive correlations were found between TNFR1 and MCT1 in the bulbar region and HbA1c and plasma creatinine, respectively. DME showed positive correlation in the bulbar region between TNFR1 and glycemia, in addition to negative correlations between CD147 in the heart versus glycemia and urea. We concluded that the initial hyperglycemic stimulus already promotes changes in the expression of genes involved in the inflammatory and metabolic pathways, and aging alters this profile. These changes prior to the onset of diseases such as DN, show that they have potential for early biomarkers studies.

Abstract
OBJECTIVE Acute kidney injury (AKI) increases mortality and costs in hospitalized patients. New methods for early AKI identification have been developed with targeted biomarkers and electronic health records data analysis. Machine learning (ML) use in diagnostics and health data analysis has recently increased. We performed a systematic review to analyze the use of ML for AKI prediction in hospitalized adults. MATERIALS AND METHODS Tubmed, EMBASE, Cochrane, and Web of Science databases were searched until 31st March of 2023. English-language studies using ML in adults for AKI prediction were included using predetermined eligibility search terms such as acute kidney injury, machine learning, and artificial intelligence. Two reviewers evaluated the publications' titles, abstracts, and full texts separately and obtained appropriate data. The main outcome was an area under the curve (AUC) result of at least 0.70. RESULTS Ten studies in 102 articles were included involving 242,251 patients. Deep learning (AUC 0.907 in critical care AKI; AUC 0.797 in hospitalized patients AKI) was similar to Logistic regression (AUC 0.877 in critical care AKI; AUC 0.789 in hospitalized patients). Decision tree constructions had similar AUC. CONCLUSIONS In this review, most ML models analyzed fulfilled the main outcome. AKI is multifactorial; however, ML performed well with different etiologies, such as cardiac-related AKI, drug-related AKI, and critical care patients. Overfitting data and constructing black box models are limitations that might jeopardize the generalization and comprehension of the results. Most studies were single-center, and three manuscripts used the same database with a predominantly Caucasian population, resulting in a lack of diversity and reducing external generalization. In conclusion, ML could effectively predict AKI in hospitalized adults. Future directions rely on including a more diverse population and completing prospective and controlled trials.

Abstract
BACKGROUND The BRCA2 gene is a well-known tumor suppressor gene implicated in breast and ovarian cancers. BRCA1/2 mutations can be sensitive to poly ADP-ribose polymerase (PARP) inhibitors such as olaparib. However, some of these patients develop resistance to this treatment and an essential factor contributing to acquired insensitivity is the occurrence of reversion mutations in the BRCA1/2 genes. CASE PRESENTATION We report the case of a 65-year-old Brazilian female patient who had previously been diagnosed with metastatic lung carcinoma carrying a BRCA2 mutation that had extended to the central nervous system. Following disease progression, olaparib was administered, resulting in a stabilizing effect on her condition for ~ 30 months. During a routine follow-up, a new triple-negative breast tumor was found. Genetic testing revealed the presence of two distinct BRCA2 gene mutations in the breast tumor. The original mutation (p.Val220Ilefs4) led to a frameshift, culminating in the production of a truncated and non-functional BRCA2 protein; the second mutation, K437fs22, rectified the reading frame of exon 11. Consequently, Rad51 could properly bind to BRCA2-an essential protein crucial for DNA repair. This restoration resulted in a functional BRCA2 protein, effectively elucidating the clinical resistance observed in the new breast tumor in this case. CONCLUSIONS This case report highlights the clinical significance of comprehensive next-generation sequencing analyses for lung adenocarcinomas, both at diagnosis and upon progression. Such analyses enable informed decisions regarding targeted therapies and facilitate a deeper comprehension of resistance mechanisms.

Abstract
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.

Abstract
Parkinson's-disease (PD) is an incurable, age-related neurodegenerative disease, and its global prevalence of disability and death has increased exponentially. Although motor symptoms are the characteristic manifestations of PD, the clinical spectrum also contains a wide variety of non-motor symptoms, which are the main cause of disability and determinants of the decrease in a patient's quality of life. Noteworthy in this regard is the stress on the cardiac system that is often observed in the course of PD; however, its effects have not yet been adequately researched. Here, an untargeted metabolomics approach was used to assess changes in cardiac metabolism in the 6-hydroxydopamine model of PD. Beta-sitosterol, campesterol, cholesterol, monoacylglycerol, α-tocopherol, stearic acid, beta-glycerophosphoric acid, o-phosphoethanolamine, myo-inositol-1-phosphate, alanine, valine and allothreonine are the metabolites that significantly discriminate parkinsonian rats from sham counterparts. Upon analysis of the metabolic pathways with the aim of uncovering the main biological pathways involved in concentration patterns of cardiac metabolites, the biosynthesis of both phosphatidylethanolamine and phosphatidylcholine, the glucose-alanine cycle, glutathione metabolism and plasmalogen synthesis most adequately differentiated sham and parkinsonian rats. Our results reveal that both lipid and energy metabolism are particularly involved in changes in cardiac metabolism in PD. These results provide insight into cardiac metabolic signatures in PD and indicate potential targets for further investigation.

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.

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
BACKGROUND Ataxia-telangiectasia (A-T) is a DNA repair disorder characterized by changes in several organs and systems. Advances in clinical protocols have resulted in increased survival of A-T patients, however disease progression is evident, mainly through metabolic and liver changes. OBJECTIVE To identify the frequency of significant hepatic fibrosis in A-T patients and to verify the association with metabolic alterations and degree of ataxia. METHODS This is a cross-sectional study that included 25 A-T patients aged 5 to 31 years. Anthropometric data, liver, inflammatory, lipid metabolism and glucose biomarkers (oral glucose tolerance test with insulin curve-OGTT) were collected. The Cooperative Ataxia Rating Scale was applied to assess the degree of ataxia. The following were calculated: Homeostasis Model Assessment-Insulin Resistance, Homeostasis Model Assessment-Adiponectin (HOMA-AD), Matsuda index, aspartate aminotransferase (AST): platelet ratio index, nonalcoholic fatty liver disease fibrosis score and BARD score. Liver ultrasonography and transient liver elastography by FibroScan® were performed. RESULTS Significant hepatic fibrosis was observed in 5/25 (20%). Patients in the group with significant hepatic fibrosis were older (p < 0.001), had lower platelet count values (p = 0.027), serum albumin (p = 0.019), HDL-c (p = 0.013) and Matsuda index (p = 0.044); and high values of LDL-c (p = 0.049), AST (p = 0.001), alanine aminotransferase (p = 0.002), gamma-glutamyl transferase (p = 0.001), ferritin (p = 0.001), 120-min glycemia by OGTT (p = 0.049), HOMA-AD (p = 0.016) and degree of ataxia (p = 0.009). CONCLUSIONS A non-invasive diagnosis of significant hepatic fibrosis was observed in 20% of A-T patients associated with changes in liver enzymes, ferritin, increased HOMA-AD, and the severity of ataxia in comparison with patients without hepatic fibrosis.

Abstract
IMPORTANCE Since the beginning of the COVID-19 pandemic, numerous metabolic alterations have been observed in individuals with this disease. It is known that SARS-CoV-2 can mimic the action of hepcidin, altering intracellular iron metabolism, but gaps remain in the understanding of possible outcomes in other pathways involved in the iron cycle. OBJECTIVE To profile iron, ferritin and hepcidin levels and transferrin receptor gene expression in patients diagnosed with COVID-19 between June 2020 and September 2020. DESIGN, SETTING AND PARTICIPANTS Cross-sectional study that evaluated iron metabolism markers in 427 participants, 218 with COVID-19 and 209 without the disease. EXPOSURES The primary exposure was positive diagnose to COVID-19 in general population of Santo André and São Bernardo cities. The positive and negative diagnose were determinate through RT-qPCR. MAIN OUTCOMES AND MEASURES Devido a evidências de alterações do ciclo do ferro em pacientes diagnosticados com COVID-19 e devido a corregulação entre hepcidina e receptor de transferrina, uma análise da expressão gênica deste último, poderia trazer insights sobre o estado de ferro celular. A hipótese foi confirmada, mostrando aumento da expressão de receptor de transferrina concomitante com redução do nível de hepcidina circulante. RESULTS Serum iron presented lower values in individuals diagnosed with COVID-19, whereas serum ferritin presented much higher values in infected patients. Elderly subjects had lower serum iron levels and higher ferritin levels, and men with COVID-19 had higher ferritin values than women. Serum hepcidin was lower in the COVID-19 patient group and transferrin receptor gene expression was higher in the infected patient group compared to controls. CONCLUSIONS AND RELEVANCE COVID-19 causes changes in several iron cycle pathways, with iron and ferritin levels being markers that reflect the state and evolution of infection, as well as the prognosis of the disease. The increased expression of the transferrin receptor gene suggests increased iron internalization and the mimicry of hepcidin action by SARS-CoV-2, reduces iron export via ferroportin, which would explain the low circulating levels of iron by intracellular trapping.

Abstract
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
BACKGROUND It has already been shown that melatonin is an antitumoral molecule that affects malignant cells via some mechanisms. The benefit played by this hormone on cancer is due to its antioxidant effects. OBJECTIVE This study aimed to evaluate the preclinical effects of melatonin in mice with the Ehrlich ascites tumor. METHODS Twenty Balb/ c male mice with Ehrlich tumor were treated with different melatonin doses. Their inflammatory and oxidative stress were accessed by gene expression. Hepatotoxicity and hematological parameters were also evaluated through biochemical analyses. Animal welfare was analysed weekly from the categories guided by the NC3Rs. RESULTS Gene expression analyses have shown that only Tnfα and Sod1 were expressed in all groups studied. Only the M-3 group showed increased Tnfα expression compared to the control. All groups treated with melatonin showed decreased Sod1 expression compared to the control. No signs of hepatotoxicity were caused by any of the melatonin doses used in the treatment. CONCLUSION In animals with Ehrlich´s tumor treated with melatonin, a decrease in oxidative stress, an amelioration in welfare and in cognitive tasks could be observed, even if the treatment has not reduced the size of the tumor itself. In parallel with the already patented use of melatonin in the treatment of sleep disorders or chronic kidney disease, our results propose its use to improve the general well-being of breast cancer patients.

Abstract
Introduction:
Yellow fever is an infectious disease endemic to Africa, and Central and
South America with a significant impact on public health, causing outbreaks and epidemics. Clinical
manifestations can vary from asymptomatic to more severe and lethal disease outcomes. The primary
prevention of yellow fever occurs through the vaccination of individuals, which confers immunity for
life. Patients with chronic kidney disease, especially those undergoing dialysis, have low vaccination
and seroconversion rates. As mentioned above, this research aimed to perform a systematic review of
the yellow fever vaccination protocol in hemodialysis patients
Methods:
A systematic review on vaccination against yellow fever in hemodialysis patients using databases, PubMed and Biblioteca Virtual em Saúde (BVS), was performed. For data collection, combinations were made using the following descriptors: protocols, vaccination, yellow fever, kidney dialysis, chronic kidney failure, chronic kidney disease, and group risk included in the title and abstract description. Articles with no subject related to the search were excluded and also if they were duplicated.
Results:
In this review, 90 scientific articles were identified in both databases. After applying exclusion criteria, a total of 3 articles were selected.
Conclusion:
We recommend carefully assessing the risk-benefit and contraindications for the patient,
emphasizing the risk groups. There is an evident lack of studies on the subject, and there is a need to
broaden investigations related toimmunization for patients on dialysis. The review is registered in the
PROSPERO system with the number 323550.

BACKGROUND The diagnosis of Type 2 Diabetes Mellitus (T2DM) is made by demonstrating the hypoglycemic condition, which involves the determination of plasma glucose, and the follow-up of hypoglycemic treatment is performed by assessing the glycated hemoglobin (HbA1c) concentration. AIM The aim of this study was to evaluate the saliva as an alternative sample in assessing the adherence to treatment with oral hypoglycemic agents in patients with Type 2 Diabetes. METHODS We selected 68 patients with T2DM, who were subjected to venous blood and saliva collection, in addition to answering a standardized questionnaire on adherence to hypoglycemic treatment. Laboratory tests performed on saliva, whole blood, serum or plasma included assessment of glycemia, urea, creatinine, uric acid, total cholesterol, HDL-cholesterol, LDL-cholesterol, VLDL-cholesterol, and glycated hemoglobin. RESULTS It was concluded that 82% of the patients adhered to hypoglycemic treatment based on glycated hemoglobin concentration (cut-off value of 7.0%). Comparing the groups that adhered to hypoglycemic treatment and those that did not adhere, statistical differences (P<0,05) were observed in the glucose, HDL-cholesterol, triglycerides, and insulin use (insulin therapy) parameters. Plasma glucose and urea serum concentration showed positive correlations when compared to saliva samples. Regarding the questionnaire, it was found that 35% of the patients presented positive screening for belief barriers and 83% positive score for recall barriers, and the positive screening correlated with glycated hemoglobin. CONCLUSION Data have shown that it is possible to use saliva as an alternative sample to the laboratory assessment of hypoglycemic treatment adherence in T2DM patients.

Abstract
Background and Aim To identify ocular findings related to SARS-CoV-2 infection in patients after the resolution of COVID-19 using complete ocular examinations and optical coherence tomography (OCT). Methods In this cross-sectional study, conducted from May 30 to October 30, 2020, patients who recovered from various stages COVID-19 underwent eye examination and multimodal retinal imaging (Retinographies and Spectral-OCT). Results We included 50 patients, 29 (58%) males, median age of 46.5 [standard deviation 15.8]. Of these, 42% (21) had mild, 18% (9) had severe and 40% (20) had critical disease. The median time interquartile range (IQR) between symptom onset and ocular examination was 55 days [IQR 39-71]. Seven patients (14%) reported ophthalmic symptoms, transitory low visual acuity (6%) and retroocular pain (8%). On OCT, one patient without comorbidities had sectoral retinal pallor suggestive of acute retinal ischaemia and oedema of the retina's inner layers and atrophy. All findings progressively and spontaneously improved months after resolution of COVID-19. Conclusion Patients with COVID-19 present findings compatible with the general population depending on age and comorbidities; nevertheless, acute retinal findings associated with the disease may be present, such as caused either by the direct effects of retinal SARS-CoV-2 infection, by indirect effects of the cytokine storm or by the pro-thrombotic state associated with COVID-19. Therefore, retinal involvement in patients with COVID-19 remains subject to considerable discussion and study.

Abstract
INTRODUCTION AND AIM Vitamin D is the name given to a group of lipid-soluble steroidal substances of physiological importance in the body, especially in bone metabolism. The active form of vitamin D is believed to have immunomodulatory effects on immune system cells, especially T lymphocytes, as well as on the production and action of several cytokines and on the expression of potent antimicrobial peptides in epithelial cells that line the respiratory tract, playing an important role in protecting the lung from infections. The aim of this study was to assess vitamin D levels in patients with COVID-19 in healthcare service and to verify that these levels are adequate to protect the progression of this infection. METHODS The aim of this observational study was to evaluate the serum concentration of vitamin D in 300 patients suspected of being infected with COVID-19, treated at Basic Health Units (BHUs) and at the Hospital Complex in the municipality of São Bernardo do Campo. RESULTS 294 patients were included, 195 (66%) of which tested positive for COVID-19 and 99 (34%) negative for COVID-19. Among the patients in the positive group, 163 patients were in the mild group (84%); 22 patients in the moderate group (11%); 8 patients in the severe group (4%), and 2 patients in the deceased group (1%). CONCLUSION For the patients in this study, no association was observed for the protective factor of vitamin D against COVID-19 infection, and its role in controlling the clinical staging of the disease was not verified.

Abstract
The aim of this study was to investigate whether the habitat of older adults living in the urban and rural areas is a contributing factor to altered serum 25(OH)D levels. An analytical, cross-sectional research with a quantitative approach was conducted in the upper backwoods of Paraíba with older adults registered at the Reference Center for Social Assistance (CRAS), addressing residents of both rural area (n = 41) and urban area (n = 43) who were randomly chosen to participate in the study. Data collection took place between January and February 2020. Higher rates of handgrip strength were observed in rural older adults (29.22 ± 8.92 Kgf) with serum 25(OH)D levels in the range of 30 to 40 ng/mL when compared to older adults with concentrations below 30 ng/mL (21.82 ± 5.00 Kgf) and above 40 ng/mL (23.47 ± 6.88 Kgf). Older people living in the urban area, with 25(OH)D levels above 40 ng/mL, presented a lower muscle power index when compared to individuals with vitamin levels from 21 to 29 ng/mL (17.40 ± 6.34 s; 15.33 ± 2.00 s). The urbanization associated with 25(OH)D levels can cause changes in skeletal and respiratory muscle strength, because the habitat associated with 25(OH)D levels affects the parameters of muscle strength of the upper limbs for older adults living in a rural area and the muscle strength of the lower limbs for those living in an urban area.

Abstract
There is an unmet medical need for effective treatments for hospitalized patients with coronavirus disease 2019 (COVID-19). Ribavirin is a broad-spectrum antiviral with demonstrated in vitro activity against multiple viruses, including severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). This trial evaluated the potential of ribavirin inhalation solution (ribavirin aerosol) to reduce COVID-19 disease severity in adults with confirmed SARS-CoV-2 infection and a diagnosis of respiratory distress. This phase I, multicenter, open-label, nonrandomized trial was conducted from February 2021 through August 2021. Patients received ribavirin aerosol (100 mg/ml for 30 min or 50 mg/ml for 60 min) twice daily for up to 6 days. The primary end point was change from baseline in clinical status severity, rated on a 7-point scale (1 [death]; 7 [not hospitalized; no limitations on activities]), at day 7 (or end-of-treatment/early termination) and day 30 (follow-up). Fifty-one patients were treated with ribavirin aerosol (mean age, 51.5 years; 78.4% men); mean number of doses was 9.7 (range, 1-12). Improvement of ≥1 level in clinical status severity was observed in 31.4% (16/51) and 78.4% (40/51) of patients at end-of-treatment and day 30, respectively. Of 21 patients who required a ventilator, 16 (76.2%) were able to discontinue ventilator use. Five patients (9.8%) died between end-of-treatment and day 30. Three patients (5.9%) discontinued study treatment due to adverse events. No deaths were considered related to study treatment. These data provide preliminary evidence that ribavirin aerosol may be an efficacious treatment for respiratory distress in adults with COVID-19.

Abstract
Objectives: To evaluate the acceptance of generic drugs in the population of Diadema, and identify factors that interfere in their choice, aiming at an improvement in assistance for these patients. Materials and methods: 203 participants were interviewed through a questionnaire containing 23 questions. The interviews were performed in Diadema city/São Paulo - Brazil. Data was expressed inpercentages; however, Chi-square test was also used for some associations and a 95% confidence interval was considered. Results: Most interviewees declared having satisfactory knowledge about generic drugs and reported previous use of it. Eighty-one point three percent of interviewed people reported that generic drugs had present the expected therapeutic effect, and 85.7% informed they believed in the safety of these drugs. The pharmacy/drugstore was the principal mean of communication to transmit information about generic medications, and a relation was observed between socioeconomic conditions and knowledge/use of these drugs. Conclusion: The studied population showed good acceptance and satisfactory knowledge about generic drugs and most of them believe in its safety. The price, the level of education, and the value of income of the population, and the low frequency of prescription, demonstrated to influence the consumption of generic drugs. Implementation of programs encouraging the prescription of these drugs and campaigns to enlighten information about generic drugs for the population could be beneficial for a better knowledge and use of them, ensuring access to health by all populations.

Abstract
While there is sustained growth of the older population worldwide, ageing is a consistent risk factor for neurodegenerative diseases, such as Parkinson’s-disease (PD). Considered an emblematic movement disorder, PD comprises a miscellany of non-motor symptoms, for which effective management remains an unfulfilled need in clinical practice. Highlighted are the cardiovascular abnormalities, that cause significant burden in PD patients. Evidence suggests that key biological processes underlying PD pathophysiology can be modulated by diet-derived bioactive compounds, such as green propolis, a natural functional food with biological and pharmacological properties. The effects of propolis on cardiac affection associated to PD have received little coverage. In this study, a metabolomics approach and Positron Emission Tomography (PET) imaging were used to assess the metabolic response to diet supplementation with green propolis on heart outcomes of rats with Parkinsonism induced by 6-hydroxydopamine (6-OHDA rats). Untargeted metabolomics approach revealed four cardiac metabolites (2-hydroxybutyric acid, 3-hydroxybutyric acid, monoacylglycerol and alanine) that were significantly modified between animal groups (6-OHDA, 6-OHDA + Propolis and sham). Propolis-induced changes in the level of these cardiac metabolites suggest beneficial effects of diet intervention. From the metabolites affected, functional analysis identified changes in propanoate metabolism (a key carbohydrate metabolism related metabolic pathway), glucose-alanine cycle, protein and fatty acid biosynthesis, energy metabolism, glutathione metabolism and urea cycle. PET imaging detected higher glucose metabolism in the 17 areas of the left ventricle of all rats treated with propolis, substantially contrasting from those rats that did not consume propolis. Our results bring new insights into cardiac metabolic substrates and pathways involved in the mechanisms of the effects of propolis in experimental PD and provide potential novel targets for research in the quest for future therapeutic strategies.

Abstract
The oxidation of 20 amino acids (AAs; alanine, arginine, asparagine, aspartic acid, cysteine (Cys), glutamic acid, glutamine, glycine, histidine, isoleucine, leucine, lysine, methionine, phenylalanine, proline, serine, threonine, tryptophan, tyrosine, and valine) by Fe(III) in a buffered aqueous solution (pH 8.0, Tris) containing 1-nitroso-2-naphthol-3,6-disulfonic acid (H2NRS) was spectrophotometrically evaluated. Under the employed conditions, Fe(III) was reduced to Fe(II) to afford greenish Fe(NRS)34−, the absorbance of which at max = 730 nm was correlated to AA reducing capacity and expressed as ascorbic acid equivalents (ASE). Comparison of the thus obtained ASE values with those determined using the Folin-Ciocalteau reagent (FCR) revealed that all analyzed AAs preferentially reacted with Fe(III)-H2NRS rather than with the FCR. The obtained insights were utilized to develop a spectrophotometric procedure for the quantitation of the total antioxidant capacity (TAC) of blood serum samples in solution containing Fe(III) and H2NRS (pH 8.0, Tris). The TAC values (in mgCys mL−1 serum) of 22 serum samples determined by the Fe(III)-NRS method were well correlated with those determined using the FCR method (r = 0.788), which suggested that the proposed procedure can be used to quantify the TAC of other protein-rich biological samples.

Abstract
Selenium has an anti-inflammatory, antioxidant, and possibly antitumoral action. Thus, we hypothesized that this element could be an ally in cancer treatment. We evaluated the effect of chelated selenium treatment of BALB/c mice with Erhlich Tumor on tumor size, histology, and biochemical parameters of the liver. A total of 96 male mice were treated for 7, 15, and 30 days with different doses of chelated selenium. During the 7 days of treatment, livers presented mild hydropic degeneration; after 15 days, the livers presented mild hydropic degeneration, inflammatory infiltrate, and steatosis, which was intensified in the animals treated for 30 days. Biochemical analysis showed an increase of the alanine transaminase enzyme in those animals, indicating hepatotoxicity. At the beginning of treatment, selenium was able to inhibit tumor growth. After 30 days of treatment, however, hepatotoxicity could be seen.

Abstract
OBJECTIVE to verify the stability of vancomycin hydrochloride in antimicrobial seal solutions with and without association of heparin sodium according to temperature and association time. METHOD an experimental study designed for the analysis of hydrogenionic potential and concentration by means of high-efficiency liquid chromatography of vancomycin hydrochloride (n=06) and vancomycin hydrochloride and heparin sodium (n=06). The solutions studied were submitted to absence of light, as well as to 22°C and 37°C. Analyses in triplicate (n=192) were performed at the initial moment (T0) and three (T3), eight (T8) and 24 hours (T24) after preparation. The data were submitted to analysis of variance (p≤0.05). RESULTS concentration of the antimicrobial at 22°C presented a reduction (T0-T8) and a subsequent increase (T24); hydrogenionic potential decreased significantly over time. At 37°C, the concentration increased up to T3 and decreased at T24, with a reduction of hydrogenionic potential up to 24 hours. Concentration of the vancomycin hydrochloride and heparin sodium solutions varied with a reduction at 22°C, accompanied by increased hydrogenionic potential. Precipitate formation was observed by visual inspection of the vancomycin hydrochloride-heparin sodium association (T3). CONCLUSION pharmacological stability of vancomycin hydrochloride (5 mg/mL) and physical incompatibility with heparin sodium (100 IU/mL) were evidenced after three hours of association in the antimicrobial seal solutions studied.

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.

Abstract
INTRODUCTION Brazil has been facing the pandemic of COVID-19 since march 2020. To date, more than 540,000 people have died from this disease in the country. There are estimates that indicate that the population exposed to SARS-CoV-2 represents 1 to 20%, however, these data are questionable due to the number of asymptomatic and untested individuals. As a result, vaccination for COVID-19 has become the main means of achieving herd immunity. OBJECTIVES To demonstrate, through local sampling, that broad and rapid vaccination may decrease the rate of COVID-19 detection in individuals potentially exposed to the SARS-CoV-2 virus. RESULTS A total of 1,128 individuals were studied, including students and health professionals from Centro Universitário FMABC, who received the two doses of the vaccine for COVID-19 (Oxford/Astrazeneca ® and CoronaVac®). There was a 41% reduction in the demand for RT-PCR test after vaccination, in the studied period. And a 78.3% reduction in positive results after vaccination started Conclusion: The results of this study showed that, even vaccinating a population with higher exposure to the risk of contamination, there was a significant reduction in test positivity and in the demand to perform these tests. Emphasizing that vaccination is the best strategy to achieve herd immunity and to reduce the spread of the disease.

Abstract
The ongoing COVID-19 pandemic represents an extra burden in the majority of public and private health systems worldwide beyond the most pessimistic expectations, driving an urgent rush to develop effective vaccines and effective medical treatments against the SARS-CoV-2 pandemic. The Nucleocapsid structural viral protein is remarkably immunogenic and hugely expressed during infection. High IgG antibodies against Nucleocapsid protein (N protein) levels were detected in the serum of COVID-19 patients, confirming its pivotal antigen role for a T lymphocyte response in a vaccine microenvironment. Currently, adverse events associated with immunizations have raised some degree of concern, irrespective of its huge benefits in dealing with disease severity and decreasing mortality and morbidity. This hitherto study evaluates histological changes in rats’ testes, epididymis, prostate, and seminal vesicles and analyzes hormone levels after solely N protein inoculation. Therefore, we exposed a group of Lewis rats to weekly injections of the recombinant N protein for 28 days, while a control group was inoculated with a buffer solution. The N group revealed a more significant number of spermatozoa. Spermatozoa in the seminiferous tubules were counted in twenty 400 × microscopy fields (mean of 9.2 vs. 4.6 in the control group; p < 0,01), but significantly lower testosterone levels (mean of 125.70 ng/dl vs. 309,00 ng/dl in the control group; p < 0,05) were found. No other histological and biochemical changes were displayed. Conclusively, these data suggest testicular hormonal imbalance mediated by the SARS-CoV-2 N protein that could be linked to reported post-COVID-19 syndrome hypogonadism. More relevant research might be performed to confirm this viral antigen’s deleterious mechanism in the human testicular microenvironment, particular in Leydig cell function.

Abstract
e12559 Background: Pathologic Complete Response (pCR) to neoadjuvant chemotherapy (NAC) in breast cancer is strongly associated with a favorable prognosis. We evaluated whether there is a correlation between serum levels of circulating tumor DNA (ctDNA) during neoadjuvant therapy with obtaining pCR and detection of residual disease after treatment. Methods: ctDNA was isolated from 310 plasma samples of 27 patients diagnosed with localized and/or locally advanced breast cancer treated with standard NAC alone or combined with immunotherapy and/or anti-HER 2- targeted therapy when indicated. Blood was collected at pretreatment, every 15 days during treatment and before surgery. Results: Eight (29%) of the 27 patients presented pCR, 4 triple negative (50%, 3 HER2+ (37%) and 1 (13%) luminal B. We observed that throughout the neoadjuvant treatment in the seventh collection the ctDNA levels were significantly higher in patients who did not presented pCR in relation to those who achieved it, p-value = 0.014. 62% of patients who presented pCR in the surgical specimen also had a complete radiological response, with a significant correlation, p-value = 0.02492. Although we did not find statistical significance, we did note that patients who presented pCR had a tendency towards an initial increase in their ctDNA levels after the first cycle of chemotherapy. Conclusions: ctDNA dosage in the third month (seventh collection) of neoadjuvant treatment is inversely correlated with the achievement of tumor pCR. The tendency we saw of an increased ctDNA levels soon after the initiation neoadjuvant chemotherapy could indicate tumor sensitivity by the increase in cell death with release of ctDNA into the circulation. Clinical trial information: NCT05050890.

Abstract
e22520 Background: Ovarian cancer mortality varies by region and age group in Brazil. However, it is still unknown if socioeconomic inequalities may affect its outcome even if indirectly as it happens for other gynecologic neoplasms in the country. Methods: Ecological study conducted with secondary data from 2016-2018 to examine the relationship between income-inequality and the amount of doctors per inhabitant on ovarian cancer mortality in Brazil. All data were gathered from Brazil’s public health system. Mortality was analyzed by sex and age, which was standardized according to the World Health Organization’s population. Income-Inequality was measured using the Gini index, obtained from the United Nations Development Programme. The number of doctors was obtained from the Unified Health System and was also calculated as the rate per 100,000 inhabitants. Linear regression was performed using stepwise selection/backward elimination. Results: Despite income inequality as measured by the Gini index not having any statistically significant relationship with ovarian cancer mortality rates, we found that the amount of doctors per inhabitant was positively associated with ovarian cancer mortality rates (β 0.037, IC95% 0.028;0.045), whereas the amount of clinical oncologists (β-0.426, IC95% -0.805; -0.047) and higher income (β -0.004, IC95% -0.005; -0.003) were all negatively associated with those rates (p < 0.05), meaning that the higher those variables, the lower the mortality. Conclusions: Ovarian cancer mortality differs among federative units in Brazil. Higher mortality is associated with a greater amount of doctors per inhabitant, whereas lower mortality rates were found to be associated with higher income and more clinical oncologists available.

Abstract
e22516 Background: Colorectal cancer mortality is expected to rise in the upcoming years in Brazil, especially in less developed regions. It is also known that socioeconomic factors play a role not only in the development, but also in the outcome of this disease. Methods: Ecological study that analyzed secondary data from 2016-2018 to examine the relationship between both income-inequality and the amount of doctors per inhabitant on colorectal cancer mortality in Brazil and its Federative Units. All data were gathered from Brazil’s public health system. Mortality was standardized by the World Health Organization’s population and analyzed by sex and age. Income-Inequality was measured using the Gini index, obtained from the United Nations Development Programme. The number of doctors was obtained from the Unified Health System and also calculated as the rate per 100,000 inhabitants. For this study, linear regression was performed using stepwise selection/backward elimination. Results: In the present study, we found that female sex (β -0.616, IC95% -1.308;0.075), the number of gastroenterologists (β -2.506, IC95% -3.702;-1.309), clinicians (β -0.107, IC95% -0.155; -0.0600), and the number of general surgeons (β -0.845, IC95% -1.188; -0.501) were negatively associated with colorectal cancer mortality, whereas higher income (β 0.02, IC95% 0.001;0.003), the amount of doctors in the public health system as a whole (β 0.090, IC95% 0.064;0.116), generalists (β 1.760, IC95% 0.987; 2.533) and oncology surgeons (β 14.252, IC95% 3.937; 24.566), were positively associated with cancer mortality. Conclusions: Colorectal cancer presents different mortality rates depending on sex, socioeconomic status and availability of medical doctors and specialists, whether for diagnosis and higher notifications or treatment and lesser deaths form the disease.

Abstract
The creation of multigene panels for prognostic and predictive purposes allows a more accurate indication of adjuvant chemotherapy for patients with breast cancer. In a previous study, we reproduced a multigene panel of 21 genes based on the commercial Oncotype-DX method. We submitted 183 embedded specimens obtained from breast surgery on patients with locoregional disease (stages I to III) between 2005 and 2010 performed at the Hospitals of the Medical School of the ABC Foundation. When we analysed the correlations between the score of the multigene panel and the progression-free interval (PFI) in all patients, we did not find a statistically significant association. However, when we selected only the 71 samples that had amplification of at least eight non-housekeeping genes, we observed that those with scores above the 75th percentile had a significantly lower PFI (p = .0054). Samples processed with nonbuffered formaldehyde were associated with a worse quality of extracted RNA (p = .004) and a significantly higher multigene panel score (p = .021). We conclude that variations in the pre-analytical processing of specimens destined for multigene panel amplification can significantly affect the results, with a potential impact on clinical management.

Abstract
The complete regression of clear cell renal cell carcinoma (ccRCC) obtained pre-clinically with anti-carbonic anhydrase IX (CAIX) G36 chimeric antigen receptor (CAR) T cells in doses equivalent to ≅108 CAR T cells/kg renewed the potential of this target to treat ccRCC and other tumors in hypoxia. The immune checkpoint blockade (ICB) brought durable clinical responses in advanced ccRCC and other tumors. Here, we tested CD8α/4-1BB compared to CD28-based anti-CAIX CAR peripheral blood mononuclear cells (PBMCs) releasing anti-programmed cell death ligand-1 (PD-L1) IgG4 for human ccRCC treatment in vitro and in an orthotopic NSG mice model in vivo. Using a ≅107 CAR PBMCs cells/kg dose, anti-CAIX CD28 CAR T cells releasing anti-PD-L1 IgG highly decrease both tumor volume and weight in vivo, avoiding the occurrence of metastasis. This antitumoral superiority of CD28-based CAR PBMCs cells compared to 4-1BB occurred under ICB via PD-L1. Furthermore, the T cell exhaustion status in peripheral CD4 T cells, additionally to CD8, was critical for CAR T cells efficiency. The lack of hepatotoxicity and nephrotoxicity upon the administration of a 107 CAR PMBCs cells/kg dose is the basis for carrying out clinical trials using anti-CAIX CD28 CAR PBMCs cells releasing anti-PD-L1 antibodies or anti-CAIX 4-1BB CAR T cells, offering exciting new prospects for the treatment of refractory ccRCC and hypoxic tumors.

Abstract
OBJECTIVE To describe the 25-hydroxyvitamin D [25(OH)D] concentrations in children and adolescents and to verify the association with the body mass index z-score (ZBMI), lipid profile and Homeostasis Model Assessment-Insulin Resistance (HOMA-IR). METHOD Cross-sectional study with 170 children and adolescents aged between 4 and 15 years (106 normal weight and 64 overweight) from a public institution in Santo André-Brazil. Weight, height and waist circumference were verified and ZBMI and waist-to-height ratio (WHtR) were calculated. Biochemical analysis: 25(OH)D levels [deficiency: 25(OH)D < 20 ng/ml]; glycemia and insulin (HOMA-IR), lipid profile and ultra-sensitive C-reactive protein. RESULTS Mean age was 8.37 ± 3.17 years; 89 (52.4%) were male; 77 (45.3%) Caucasians and 121 (71.2%) pre-pubescent. Overweight was observed in 64 (37.6%), dyslipidemia in 108 (63.5%) and 25(OH)D deficiency in 117 (68.8%) of the individuals. ZBMI (r = -0.209; p = 0.006), WHtR (r = -0.154; p = 0.045), triglycerides (TGs) (r = -0.161; p = 0.037) and TGs/high-density lipoprotein (HDL) ratio (r = -0.168; p = 0.028) were inversely correlated with 25(OH)D concentrations. Overweight children and adolescents were four times more likely to have vitamin D deficiency (odds ratio = 4.28; 95% confidence interval 1.152 to 4.907; p = 0.019), after adjustment for pubertal development (prepubertal), sex (male), HDL-c (<45 mg/dl), non-HDL (>120 mg/dl), TG/HDL ratio (>2.0) and HOMA-IR. CONCLUSIONS A high prevalence of vitamin D deficiency (68.8%) was observed. There was an independent association between vitamin D deficiency and overweight, not observed for dyslipidemia and insulin resistance. The data point to the need for periodic monitoring of serum concentrations of 25(OH)D and reinforcement of guidelines for combating and preventing overweight in the pediatric age group.

Abstract
Introdução: Diversos estudos têm mostrado que a mobilização precoce é segura e benéfica para pacientes internados em unidades de terapia intensiva (UTIs), especialmente para aqueles com ventilação mecânica (VM). Objetivo: Investigar os benefícios das técnicas fisioterapêuticas de mobilização precoce aplicada aos pacientes que sofreram traumatismo cranioencefálico (TCE). Métodos: Trata-se de um estudo quasi-randomizado, que incluiu 27 com TCE divididos em dois grupos: controle (n=13) e experimental (n=14) pacientes. No grupo experimental, os pacientes sedados foram submetidos à mobilização e alongamentos passivos nos membros superiores e inferiores; naqueles sem sedação, foram incluídos exercícios ativo-assistidos, livres e resistidos. Resultados: O grupo experimental foi composto por 51,8% dos participantes da pesquisa e o grupo controle por 48,2%, sendo a maioria do sexo masculino (81,5%) com mediana de idade de 43 anos. Os pacientes do grupo experimental apresentaram média de 9,5 dias (2,2-14,7) de ventilação mecânica, e os pertencentes ao grupo controle, de 17 dias (7-21,7) com de VM (p=0,154). Os pacientes do grupo experimental apresentaram média de 13,5 dias de internação em UTI, contra média de 17 dias do grupo controle (p=0,331), e média de 20,5 dias de internação hospitalar contra 24 dias do grupo controle (p=0,356). Conclusão: A mobilização precoce é uma técnica que deve ser aplicada em pacientes críticos dentro das UTIs, pois pode diminuir o tempo de internação na UTI e hospitalar.

Abstract
BACKGROUND The practice of regular physical activity can alter the lipid profile in populations according to diverse demographic characteristics. OBJECTIVE To evaluate the association of physical inactivity with the lipid profile among vulnerable populations. METHODS A cross-sectional study was conducted among 349 vulnerable individuals from Tocantins state, northern Brazil. The International Physical Activity Questionnaire 7 Day short form was used to measure self-reported physical activity levels. Venous blood samples were drawn to evaluate lipid profile. Logistic regression adjusted by the socioeconomic variables was used to analyse the effects of physical inactivity on the lipidic profile. The level of significance was 5% and Stata® (StataCorp, LC) version 11 was used. RESULTS We observe an inverse relationship between physical inactivity and HDL-C-that is, those who were sedentary or below the WHO Recommendations for physical activity were at 2.6 greater odds (IC95% 1.21, 5.67; p = 0.015) of having a lower HDL compared with those meeting or exceeding WHO physical activity recommendations. CONCLUSION On the vulnerable populations studied, the insufficiently active or sedentary individuals (called the physical inactivity individuals) have more risk of the altered HDL-C.

Abstract
Objective:
The objective of this study is to analyze the characteristics of insertion and
maintenance of 163 peripherally inserted central venous catheters in juvenile patients oncological.
Methods:
This is an observational study of a cross-sectional and longitudinal collection, with quantitative
approach of secondary data from patient’s medical records that underwent the procedure
for a peripheral insertion central catheter implantation, carried out in a non-profit Health Institution
(HI) in Sao Paulo, Brazil, specialized in the treatment of childhood-juvenile cancer, and which attends
children and adolescents from all regions of Brazil.
Results:
The measurement of the external catheter, when greater than 2 centimeters, negatively influences
the period of the segment used (p = 0.007) and is associated with catheter removal for unforeseen
causes (p = 0.013); displacement was the main cause of unexpected removal of peripherally
inserted central venous catheter.
Conclusion:
Peripherally inserted central venous catheter is a safe option when the entire therapeutic
trajectory is reached.

Abstract
Background Globally, stroke remains an important cause of death and long-term disability, and the impact of coronavirus disease (COVID-19) on the health system may have impaired stroke care. Previous studies suggest significant reduction in hospital admissions for stroke after COVID-19 onset as patients may hesitate seeking medical help due to fear of exposure. Methods This cross-sectional study included cases of hospital admissions for stroke, identified from the Hospital Information System of the Unified Health System (Sistema Único de Saúde), which contains official and public data in Brazil. Data were collected in duplicate, then categorized according to the International Classification of Diseases, tenth revision (ICD-10), considering codes I60–I69. Linear regression was used to estimate the variation in hospital admissions for stroke in the city of São Paulo (SP) − the largest and most populous city in Brazil and Latin America, between January and June of each analyzed year (2017–2020). The percentage variation between June and January 2020 was also compared. The level of significance was set at 5%, and the statistical program used was Stata, version 14.0. Results In the city of SP, during the first wave of COVID-19, from January to June 2020, there were registered decreases in absolute numbers and mean monthly admissions for stroke. Compared to January 2020, data from June 2020 showed 17% reduction in hospitalizations for intracerebral hemorrhage, 32% for cerebral infarction, 26% for stroke unspecified, and 47% for other cerebrovascular diseases. Conclusion We argue for policies aimed at improving stroke care and developing awareness campaigns regarding the importance of early diagnosis and treatment, as even in less severe presentations, stroke can trigger an increase in mortality, cost, and long-term disability.

Abstract
OBJECTIVES To assess nutritional status regarding selenium in adolescents with Juvenile Systemic Lupus Erythematosus (jSLE) and analyze possible associations with disease activity, insulin resistance and lipid profile. METHODS This was an observational, cross-sectional study of 31 female adolescents with jSLE and 31 healthy female volunteers as a comparison group. We obtained demographic, anthropometric (weight, stature, waist, and neck circumferences), and clinical data (disease activity measured by SLEDAI-2K) from both groups; laboratory data including: lipid profile, plasma selenium, erythrocyte glutathione peroxidase activity (GPx), plasma malondialdehyde (MDA), ultrasensitive C-reactive protein (usCRP), insulin levels, and glycemia (Homeostasis Model Assessment for Insulin Resistance-HOMA-IR). RESULTS Mean age at diagnosis of jSLE group was 15.9±1.7 years, with mean disease duration of 3.6±2.6 years. 48% of patients and controls had below-reference Se levels (≤46mcg/L). GPx was more frequently below reference levels (<4.171U/L) in the jSLE group, compared to controls. A ROC curve was used to assess the power of the variables to discriminate between both groups; insulin (AUC = 0.712; CI 95% 0.584-0.840), waist-to-height ratio (AUC = 0.704; CI 95% 0.572-0.837), and HOMA-IR (AUC = 0.689; CI 95% 0.556-0.822) were the variables with the greatest discriminatory power. Linear regression showed an independent inverse association between Se levels and c-LDL; no such correlation was found for GPx activity. SLEDAI-2 K and HOMA-IR showed no association with levels of Se and GPx activity. CONCLUSIONS Approximately, 50% of jSLE adolescents had below reference Se levels. The frequency of inadequate GPx values was higher in patients, compared to controls. There was an independent inverse association between Se and c-LDL levels in both groups; this was not the case for HOMA-IR and SLEDAI-2K. The data show the importance of assessing Se nutritional status in jSLE patients.

Abstract
Case Presentation Arboviruses primarily consist of RNA, which favours greater genetic plasticity, with a higher frequency of mutations that allow the virus to adapt to different hosts. The initial symptomatology is nonspecific, in that the patient can present fever, myalgia, arthralgia, rash and headache. This makes a clinical diagnosis using laboratory tests difficult and time-consuming. In Brazil, the main arboviruses involved in epidemics belong to the family Flaviviridae. The patient in this case is from the municipality of São Bernardo do Campo, an area endemic for arboviruses. He presented symptoms of fever, myalgia and headache. Results The multiplex assay for arboviruses detected genetic material from the dengue 2 and yellow fever viruses. Conclusion This result confirms the importance of molecular tests showing high sensitivity and specificity that can assist clinical diagnosis, particularly in endemic areas during periods of outbreak for other arboviruses, like the epidemiological picture in Brazil in 2018, when significant co-circulation of dengue virus and yellow fever virus occurred. The presence of co-circulating arboviruses increases the chance of coinfection and demonstrates the importance of differential diagnosis.

Abstract
Abstract Objective: to verify the stability of vancomycin hydrochloride in antimicrobial seal solutions with and without association of heparin sodium according to temperature and association time. Method: an experimental study designed for the analysis of hydrogenionic potential and concentration by means of high-efficiency liquid chromatography of vancomycin hydrochloride (n=06) and vancomycin hydrochloride and heparin sodium (n=06). The solutions studied were submitted to absence of light, as well as to 22°C and 37°C. Analyses in triplicate (n=192) were performed at the initial moment (T0) and three (T3), eight (T8) and 24 hours (T24) after preparation. The data were submitted to analysis of variance (p≤0.05). Results: concentration of the antimicrobial at 22°C presented a reduction (T0-T8) and a subsequent increase (T24); hydrogenionic potential decreased significantly over time. At 37°C, the concentration increased up to T3 and decreased at T24, with a reduction of hydrogenionic potential up to 24 hours. Concentration of the vancomycin hydrochloride and heparin sodium solutions varied with a reduction at 22°C, accompanied by increased hydrogenionic potential. Precipitate formation was observed by visual inspection of the vancomycin hydrochloride-heparin sodium association (T3). Conclusion: pharmacological stability of vancomycin hydrochloride (5 mg/mL) and physical incompatibility with heparin sodium (100 IU/mL) were evidenced after three hours of association in the antimicrobial seal solutions studied.

Abstract
BACKGROUND AND AIM DNA repair systems are functionally essential for the maintenance of life and among these, we can highlight the MutS system, subdivided into MutSα (hMSH2 and hMSH6) and MutSβ (hMSH2 and hMSH3). The objective of this study was to analyze the expression of hMSH2 and hMSH6 repair genes in radiology technicians exposed to low radiation doses. METHODS Thirty workers occupationally exposed to ionizing radiation and twenty-five non-exposed were included in this study. Gene expression was analyzed by qPCR. Peripheral blood samples were collected from both groups for total RNA isolation. RESULTS It was observed a five-fold increase (p=0.006) in the hMSH2 repair gene expression in those exposed to radiation and a weak but significant correlation (p=0.041) with the hMSH6 genes when we associated the number of hours of exposure with gene expression. CONCLUSIONS The longer the exposure time, the greater the activation of this component of the repair system. APPLICATION TO PRACTICE Blood count parameters could did not alter with radiation exposure. X-rays used by radiology technicians in imaging tests can damage the DNA to the point of activating the MutS repair system and that there is a greater tendency of expression of this system in professionals that had undergone longer exposure.
