How the COAPT trial affected the selection of patients with secondary mitral regurgitation undergoing transcatheter edge-to-edge repair: insights from the GIOTTO Registry.

Background: The impact of the COAPT results on clinical practice has not yet been investigated in large real-world cohort study. The aim of the study is to evaluate the potential impact of the COAPT trial by analyzing the temporal trends of baseline characteristics and outcome of secondary mitral regurgitation (SMR) patients undergoing MitraClip (MC) included in the GIOTTO registry.

Methods: The study population was divided into two groups, considering the enrolment before or after the COAPT publication.

Allogeneic Hematopoietic Cell Transplantation in Elderly Patients in a Latin American Country: Analysis of 11 Year of Data from the Brazilian Registry SBTMO/CIBMTR.

This study analyzed recent changes in the utilization of allogeneic hematopoietic cell transplantation (HCT) for treatment of acute myeloid leukemia (AML), myelodysplastic syndrome (MDS), and myeloproliferative diseases (MPDs) and the survival of HCT recipients ≥60 years of age in Brazil. This retrospective registry study included patients who received a first allogeneic HCT from any donor between 2012 and 2023. Of the 6657 patients, 444 (7%) were 60 years of age or older who received grafts from human leukocyte antigen (HLA)-matched related (42%) or unrelated (20%) donors or HLA-haploidentical donors (32%).

THE IMPACT OF THE COVID-19 PANDEMIC RESTRICTIVE MEASURES ON THE DIAGNOSIS OF ADENOMATOUS POLYPS AND COLORRECTAL ADENOCARCINOMA IN A POPULATION SUBMITTED TO COLONOSCOPY.

Background: Colorectal cancer (CRC) is globally the third most common malignant neoplasm and the second leading cause of cancer-related death worldwide. The COVID-19 pandemic led to the suspension of routine screening tests by health services. A 35.

A novel approach to triazole fungicides risk characterization: Bridging human biomonitoring and computational toxicology.

Brazil stands as the world's leading coffee producer, where the extensive use of pesticides is economically critical yet poses health and environmental risks due to their non-selective mechanisms of action. Specifically, triazole fungicides are widely used in agriculture to manage fungal diseases and are known to disrupt mammalian CYP450 and liver microsomal enzymes. This research establishes a framework for risk characterization of human exposure to triazole fungicides by internal-dose biomonitoring, biochemical marker measurements, and integration of high-throughput screening (HTS) data via computational toxicology workflows from the Integrated Chemical Environment (ICE).

Progression and perceptual responses to blood flow restriction resistance training among people with multiple sclerosis.

Purpose: Resistance exercise can attenuate muscular impairments associated with multiple sclerosis (MS), and blood flow restriction (BFR) may provide a viable alternative to prescribing heavy training loads. The purpose of this investigation was to examine the progression of upper and lower body low-load (30% of one-repetition maximum [1RM]) resistance training (RT) with BFR applied intermittently during the exercise intervals (RT + BFR) versus volume-matched heavy-load (65% of 1RM) RT.

Methods: Men and women with MS (n = 16) were randomly assigned to low-load RT + BFR (applied intermittently) or heavy-load RT and completed 12 weeks (2 × /week) of RT that consisted of bilateral chest press, seated row, shoulder press, leg press, leg extension, and leg curl exercises.

Biomonitoring and risk assessment of human exposure to triazole fungicides.

Risk assessment and biomarkers were evaluated in volunteers exposed to triazole fungicides in southern Minas Gerais, Brazil. Volunteers were divided into two groups: occupationally and environmentally exposed to pesticides (n = 140) and those unexposed (n = 50) from urban areas. Urine samples were analyzed by GC-MS for triazoles, and samples from men and women in the exposed group were quantified.

Characterization of biomarkers in blood serum for cancer diagnosis in dogs using Raman spectroscopy.

Biomarkers of cancer in sera of domestic dogs were detected through Raman spectroscopy with 830 nm excitation. Raman spectra of sera from 61 dogs (31 healthy and 30 with cancer, resulting in 154 and 200 spectra, respectively) were submitted to principal component analysis (PCA) for feature extraction and partial least squares (PLS) regression for discrimination between Healthy and Cancer groups. In the PCA, the peaks at 1132, 1342, 1368, and 1453 cm (albumin and phenylalanine) were higher for the Cancer group.

[Definition, classification and diagnosis of myocardial infarction with non-obstructive coronary artery disease: where do we stand?].

The systematic use of coronary angiography and the availability of increasingly sensitive biomarkers of myocardial cytolysis have determined an increase in the diagnosis of myocardial infarction with non-obstructed coronary arteries (MINOCA), which is currently reported in 5-20% of patients with acute myocardial infarction. The first diagnostic criteria of MINOCA were reported by a position paper of the European Society of Cardiology in 2017; since then, these criteria have been revised several times until the current version. The diagnosis of MINOCA requires not only the presence of myocardial damage, indicated by the detection of a rise or fall in cardiac troponin with at least one value above the 99th percentile upper reference limit, but also the clinical evidence of acute myocardial infarction as shown by symptoms, ECG, or imaging.

Beta-blockers and renin-angiotensin system inhibitors for Takotsubo syndrome recurrence: a network meta-analysis.

Introduction: Takotsubo syndrome (TTS) is an acute heart failure syndrome, featured by transient left ventricular systolic dysfunction. Recurrences of TTS are not infrequent and there is no standard preventive therapy. The aim of this study was to evaluate in a network meta-analysis if beta-blockers (BB) and ACE inhibitors/angiotensin receptor blockers (ACEi/ARBs), in combination or not, can effectively prevent TTS recurrences.

Assessment of cellular damage with cytome assay among environmental/occupational triazole.

The use of triazole fungicides is common in Minas Gerais, Brazil. However, the risk arising from excessive and often unprotected exposure can be harmful to farmers. Therefore, we evaluated volunteers, exposed to triazole fungicides for cellular damage caused by this pesticide.
