EPIDEMIOLOGY OF TRAUMATIC FRACTURES OF THE SPINE IN MARIO COVAS HOSPITAL BETWEEN 2015 AND 2020.

Objectives: Analyze the epidemiological profile of patients with traumatic spinal fractures treated at Mário Covas State Hospital between 2015 and 2020.

Methodology: This is an epidemiological, descriptive, retrospective, quantitative, comparative, medical records review-type study. Data collection was carried out between May and June 2022 at the Mário Covas State Hospital, the following characteristics being evaluated: age, sex, lesion topography, trauma mechanism, origin and treatment.

Influence of chlorhexidine digluconate on biocompatibility of cements: Morphological and immunohistochemistry analysis.

In this study, the in vivo biocompatibility was evaluated by using conventional ionomer cements modified with Chlorhexidine (CHX) in different time intervals. In total, 105 male Wistar rats were randomized into seven groups: control, groups M, M10, M18 and groups RL, RL10, RL18 (M-Meron and RL-RivaLuting, and added CHX-10% and CHX-18%, respectively). Histological analyses of inflammatory infiltrate and collagen fibers, and immunohistochemistry of CD68+ for macrophages (MOs) and multinucleated giant cells (MGCs) were performed.

Acute organ failure and risk of admission to intensive medical care in cancer patients: a single center prospective cohort study.

Objective: To ascertain the cumulative incidence of acute organ failure and intensive care unit admission in cancer patients.

Methods: This was a single-center prospective cohort study of adult cancer patients admitted for unscheduled inpatient care while on systemic cancer treatment.

Results: Between August 2018 and February 2019, 10,392 patients were on systemic treatment, 358 had unscheduled inpatient care and were eligible for inclusion, and 285 were included.

Effect of Yellow Propolis on Biocompatibility of Cements: Morphological and Immunohistochemistry Analysis.

Objective:  The focus of this study was to evaluate the biocompatibility of ionomer cements modified with ethanolic extracts of propolis (EEP) in different concentrations and time intervals.

Materials And Methods:  In total, one hundred and thirty-five male Wistar rats were randomized into nine groups: Control, Groups Meron, and Groups Ketac (conventional, and added with 10, 25, 50% EEP, respectively). Histological analyses of inflammatory infiltrate and collagen fibers, and immunohistochemistry of CD68+ for macrophages (MOs) and multinucleated giant cells (MGCs) were performed.

CTAB-modified carboxymethyl cellulose/bagasse cryogels for the efficient removal of bisphenol A, methylene blue and Cr(VI) ions: Batch and column adsorption studies.

The simultaneous removal of organic and inorganic pollutants from water requires multifunctional adsorbents. Cryogels of carboxymethyl cellulose (CMC) and sugarcane bagasse (BG) were modified with cetyltrimethylammonium bromide (CTAB) micelles for the adsorption of methylene blue (MB), Cr(VI) ions and bisphenol A (BPA) separately, in binary or ternary aqueous mixtures. Batch adsorption studies of MB and Cr(VI) and BPA on the CMCBG-CTAB adsorbents indicated removal capacities of 100%, 70% and 95%, respectively.
