Objectives:The Brazilian Unified Health System(SistemaÚnico de Saúde−SUS)is the universal public healthcare system of Brazil that maintains a nationwide database of its *** primary objective was to analyze regional and temporal trends,while our secondary goal was to establish correlations between states’health economy status and their prostate cancer(PCa)***:We analyzed Brazil’s nationwide data on prostate cancer(PCa)incidence,mortality,and care gathered between 2013 and 2021 by the Information Technology Department of SUS(DATA-SUS),updated monthly using the International Classification of Diseases(ICD-10)***:In the period,273,933 new cases of PCa and 135,336 PCa deaths were reported in men aged 50 years or over in *** median annual PCa-specific incidence rate(PCSIR)ranged from 14.7 in the Southeast to 6.9 in the North region and the median annual PCa-specific mortality rate(PCSMR)ranged from 7.7 in the Northeast to 6.0 in the South region(per 10,000 men>50).The median annual mortality to incidence ratio(MIR)was highest in the North(0.88)and lowest in the Southeast region(0.44).There were significant regional differences in PCa treatment rates(per new cases);the Midwest region had the highest median annual surgery rate(0.63)while the North region had the highest median annual systemic therapy rate(0.75)and the lowest radiation therapy rate(0.06).Temporal analysis of the data showed significant change in annual rate trends after the year 2018 for PCSIR(coefficient[β]=+3.66,p<0.001),any treatment(β=−0.06,p=0.016),surgery([SR]β=+0.05,p=0.017)radiation therapy([RTR]β=−0.06,p=0.005)and systemic therapy([STR]β=−0.10,p=0.002).After the 2020 pandemic,annual PCSIR decreased(β=−2.15,p=0.002)but annual PCSMR,MIR,and treatment rates remained *** studies showed that the PCSIR was strongly negatively correlated with STR(p<0.001)and positively correlated with RTR(p=0.004).MIR was positively correlated with STR(p<0.001)and ne

Objective: Metabolomics has been extensively utilized in bladder cancer (BCa) research, employing mass spectrometry and nuclear magnetic resonance spectroscopy to compare various variables (tissues, serum, blood, and urine). This study aimed to identify potential biomarkers for early BCa ***: A search strategy was designed to identify clinical trials, descriptive and analytical observational studies from databases such as Medline, Embase, Cochrane Central Register of Controlled Trials, and Latin American and Caribbean Literature in Health Sciences. Inclusion criteria comprised studies involving BCa tissue, serum, blood, or urine profiling using widely adopted metabolomics techniques like mass spectrometry and nuclear magnetic resonance. Primary outcomes included description of metabolites and metabolomics profiling in BCa patients and the association of metabolites and metabolomics profiling with BCa diagnosis compared to control patients. The risk of bias was assessed using the Quality Assessment of Studies of Diagnostic ***: The search strategy yielded 2832 studies, of which 30 case-control studies were included. Urine was predominantly used as the primary sample for metabolite identification. Risk of bias was often unclear inpatient selection, blinding of the index test, and reference standard assessment, but no applicability concerns were observed. Metabolites and metabolomics profiles associated with BCa diagnosis were identified in glucose, amino acids, nucleotides, lipids, and aldehydes ***: The identified metabolites in urine included citric acid, valine, tryptophan, taurine, aspartic acid, uridine, ribose, phosphocholine, and carnitine. Tissue samples exhibited elevated levels of lactic acid, amino acids, and lipids. Consistent findings across tissue, urine, and serum samples revealed downregulation of citric acid and upregulation of lactic acid, valine, tryptophan, taurine, glutamine, aspartic acid, uridine, rib
