Outcomes of the Subsequent Periprosthetic Joint Infection Revisions after a Failed Debridement, Antibiotics and Implant Retention: A Multicentric Study of 197 Patients.

The impact of prior unsuccessful debridement, antibiotics, and implant retention (DAIR) procedures on subsequent revisions is uncertain, with conflicting evidence. Despite 85% consensus against the second DAIR procedure following the 2018 International Consensus Meeting, a 2020 study reported high success rates for the aforementioned second DAIR procedure. We conducted a multicenter observational study reviewing data from patients with failed DAIR procedures between 2005 and 2021.

Anti-SARS-CoV-2 serology based on ancestral RBD antigens does not correlate with the presence of neutralizing antibodies against Omicron variants.

Unlabelled: Neutralizing antibody titers and binding antibody levels are considered correlates of protection against severe SARS-CoV-2 infection. The clinical utility of serology should be reevaluated in light of the emergence of escape variants, as commercial antibody-binding assays have not been adapted to the virus' antigenic evolution. We compared anti-SARS-CoV-2 antibody titers in four quantitative serological tests based on variable ancestral spike antigens (three in-house ELISAs and the prototype VIDAS SARS-CoV-2 IgG QUANT assay) and neutralization assays against the pseudotyped Wuhan, BA.

This retrospective cross-sectional observational study aimed to report the characteristics of osteosarcomas of the jaws diagnosed in an oral pathology reference laboratory.

Material And Methods: Information (gender, location of origin, age, symptoms, lesion evolution time, and clinical appearance) regarding the cases diagnosed as osteosarcomas between 2001 and 2023 were obtained from histopathology reports, exam request forms, and clinical photographs.

Oximic compounds as potential inhibitors of metacaspase-2 (TbMCA2) of Trypanosoma brucei.

Metacaspases are a distinct class of cysteine proteases predominantly found in plants, fungi, and protozoa, crucial for regulating programmed cell death (PCD). They possess unique structural features and differ markedly from caspases in their activation mechanisms and substrate specificities, with a notable preference for binding basic residues in substrates. In this study, we introduced vanillin-derived oximic compounds to explore their pharmaceutical potential.

Phosphate is associated with frailty in older patients with chronic kidney disease not on dialysis.

Purpose: Frailty is common in older patients with chronic kidney disease (CKD) and has been considered an independent risk factor for adverse clinical outcomes in this population. CKD-associated mineral and bone metabolism (CKD-MBD) increases energy expenditure and causes malnutrition and inflammation leading to frailty. We investigated whether CKD-MBD markers and energy metabolism are associated with frailty in patients with advanced CKD on conservative management.

Sex differences in the anticompulsive-like effect of memantine: Involvement of nitric oxide pathway but not AMPA receptors.

Memantine, an N-Methyl-D-Aspartate (NMDA) antagonist, has been examined as a potential treatment for Obsessive-Compulsive Disorder (OCD). Yet, there is limited knowledge regarding how it works to reduce compulsive behaviour and whether it has different effects on individuals based on their sex. Herein, we investigated if there are sex differences in the anticompulsive-like effect of memantine in adult Swiss mice.

Shorter Reperfusion Time in Stroke is Associated with Better Cognition.

Background: Cognitive changes that result from cerebrovascular disease contribute to a poor functional outcome with reduced quality of life. Among patients undergoing endovascular therapy (EVT), we aim to assess cognitive function and evaluate the impact of reperfusion time in cognitive performance.

Methods: Patients with acute right anterior circulation strokes that underwent EVT between January 2018 and August 2020 at Centro Hospitalar de Vila Nova de Gaia/Espinho, participated in the study.

The Green Tea Polyphenol Epigallocatechin-Gallate (EGCG) Interferes with Microcin E492 Amyloid Formation.

Microcin E492 (MccE492) is an antimicrobial peptide and proposed virulence factor produced by some strains, which, under certain conditions, form amyloid fibers, leading to the loss of its antibacterial activity. Although this protein has been characterized as a model functional amyloid, the secondary structure transitions behind its formation, and the possible effect of molecules that inhibit this process, have not been investigated. In this study, we examined the ability of the green tea flavonoid epigallocatechin gallate (EGCG) to interfere with MccE492 amyloid formation.

Antimicrobial resistance, pathogenic potential, and genomic features of carbapenem-resistant isolated in Chile: high-risk ST25 clones and novel mobile elements.

Multidrug- and carbapenem-resistant (CR-) are critical threats to global health and key traffickers of resistance genes to other pathogens. Despite the sustained increase in CR- infections in Chile, few strains have been described at the genomic level, lacking details of their resistance and virulence determinants and the mobile elements mediating their dissemination. In this work, we studied the antimicrobial susceptibility and performed a comparative genomic analysis of 10 CR- isolates from the Chilean surveillance of carbapenem-resistant .

Applying the bioisosterism strategy to obtain lead compounds against SARS-CoV-2 cysteine proteases: An in-silico approach.

SARS-CoV-2 cysteine proteases are essential nonstructural proteins due to their role in the formation of the virus multiple enzyme replication-transcription complex. As a result, those functional proteins are extremely relevant targets in the development of a new drug candidate to fight COVID-19. Based on this fact and guided by the bioisosterism strategy, the present work has selected 126 out of 1050 ligands from DrugBank website.
