Ustekinumab (UST) is an interleukin-12/interleukin-23 receptor antagonist approved for the treatment of Crohn's disease (CD). Only limited real-life data on the long-term outcomes of CD patients treated with UST are available. This study assessed UST's long-term effectiveness and safety in a large population-based cohort of moderate to severe CD patients.

Purpose: Mild Traumatic brain injury is classified based on Glasgow Coma Scale (GCS 13-15), it also involves transient alteration of brain function, which may lead to severe short- and long-term sequelae. When treating a patient with a mild head injury outside the hospital, it is of crucial importance to decide whether to transport him to a center without neurosurgery or to a center equipped with neurosurgery (primary centralization). Recent decades have seen exploration of portable, non-invasive devices for intracranial injury and stroke detection, with microwave frequency electromagnetic field technology showing promising clinical outcomes.

Background: Infections by carbapenem-resistant Pseudomonas aeruginosa (CRPA) have been associated with high morbidity and mortality among solid organ recipients.

Objectives: To delineate the epidemiological and molecular characteristics of a recurrent outbreak of imipenem (IMP)-producing P. aeruginosa (CRPA) among kidney transplant (KT) recipient METHODS: We described a recurring CRPA outbreak in a KT ward, divided into two periods: before unit closure (Feb 2019-2020) and after reopening (Aug 2020-Dec 2023).

Bats are becoming recognised as new model species to study naturally evolved mammalian extended healthspan and disease tolerance. However, this research is limited by the lack of bat specific cellular resources. Here we describe an optimised protocol to develop both primary and immortalised fibroblast cell-lines from wing biopsy punches from the Egyptian fruit bat, Rousettus aegyptiacus.

Although diphtheria is a vaccine-preventable disease, numerous cases are still reported around the world, as well as outbreaks in countries, including European ones. Species of the Corynebacterium diphtheriae complex are potentially toxigenic and, therefore, must be considered given the possible consequences, such as the circulation of clones and transmission of antimicrobial resistance and virulence genes. Recently, Corynebacterium rouxii was characterized and included among the valid species of the complex.

Cases of diphtheria, even in immunized individuals, are still reported in several parts of the world, including in Brazil. New outbreaks occur in Europe and other continents. In this context, studies on Corynebacterium diphtheriae infections are highly relevant, both for a better understanding of the pathogenesis of the disease and for controlling the circulation of clones and antimicrobial resistance genes.

Article Synopsis
  • Public health is increasingly challenged by pathogenic microorganisms with new antimicrobial resistance, making identification difficult for emerging pathogens like NDM-1-producing strains.
  • A study documents Brazil's first case of a new ST418 strain, initially misidentified, which was accurately identified through ANI analyses and whole-genome sequencing.
  • The study found that the resistance gene was located on a 112 kb IncFIB plasmid, emphasizing the need for public health vigilance as this species may spread significant resistance genes.

Background: COVID-19 pandemic characterised a unique and vulnerable social, emotional, and health environment for pregnancy, with potential long-lasting risks to maternal and child health outcomes. In women who were pregnant at the peak of COVID-19 pandemic, we investigated the association between pandemic-related concerns about pregnancy and delivery and both the parent's (i.e.

  • - Dengue virus serotype 2, genotype Cosmopolitan (DENV-2-GII), is widely distributed and was newly identified in Brazil, having been present in other regions since 2019.
  • - A study sequenced 237 confirmed DENV-2 cases from March 2021 to March 2023, discovering that DENV-2-GII circulates in all areas of Brazil, having been introduced multiple times between 2020 and 2022.
  • - Despite its presence, DENV-1 dominated the Brazilian dengue epidemic in 2022, suggesting pre-existing immunity from prior DENV-2-GIII infections may limit symptomatic cases of DENV-2-GII, highlighting the need for ongoing

Background: Ustekinumab (UST) is an interleukin-12/interleukin-23 receptor antagonist recently approved for treating ulcerative colitis (UC) but with limited real-world data. Therefore, we evaluated the effectiveness and safety of UST in patients with UC in a real-world setting.

Research Design And Methods: This is a multicenter, retrospective, observational cohort study.

We present a case of skin lesion caused by nontoxigenic Corynebacterium diphtheriae. Genomic taxonomy analyses corroborated the preliminary identification provided by mass spectrometry. The strain showed a susceptible phenotype with increased exposure to penicillin, the first drug of choice for the treatment.

  • Over the last ten years, New Delhi metallo-beta-lactamase (NDM) has spread in Brazil among various Enterobacterales species, not just Klebsiella.
  • The study involved analyzing 32 clinical isolates from 11 different species, with a focus on their antibiotic resistance profiles, revealing the presence of key resistance genes such as bla and mcr-1.
  • The findings highlight the urgent need for improved detection and control measures in hospitals to prevent the further spread of these resistant bacteria.

  • * The research involved various methods like antimicrobial susceptibility testing, whole genome sequencing, and conjugation assays to understand the strain's resistance mechanisms and plasmid characteristics.
  • * The findings reveal that strain 195_20 is resistant to multiple antibiotics and carries three significant plasmids related to its resistance genes, highlighting the risk of transmission of these resistant pathogens from animals to humans.

Article Synopsis
  • Carbapenem-resistant Klebsiella pneumoniae (CRKP) is a significant global health threat due to its widespread resistance to multiple antimicrobial agents, necessitating the exploration of new treatment options.
  • In a study of 97 isolates from Brazilian hospitals, the majority were found to be extensively drug-resistant, with the most effective treatments being meropenem-vaborbactam, cefiderocol, and ceftazidime-avibactam.
  • The results highlight a critical need for proper antimicrobial stewardship to protect the effectiveness of remaining treatment options, especially since only ceftazidime-avibactam is currently available in Brazil.

Diphtheria is an infectious disease potentially fatal that constitutes a threat to global health security, with possible local and systemic manifestations that result mainly from the production of diphtheria toxin (DT). In the present work, we report a case of infection by Corynebacterium diphtheriae in a cutaneous lesion of a fully immunized individual and provided an analysis of the complete genome of the isolate. The clinical isolate was first identified by MALDI-TOF Mass Spectrometry.

, an opportunistic pathogen causing infections in immunocompromised patients, usually shows pronounced antimicrobial resistance. In recent years, the frequency of carbapenemases in has decreased, which allows use of new beta-lactams/combinations in antimicrobial therapy. Therefore, the in vitro evaluation of these drugs in contemporary isolates is warranted.

Background: Developing and implementing home telehealth (HTH) services for patients with chronic conditions is a challenge. HTH services provide continuous and integrated care to patients, but very often pilot projects face non-adoption and abandonment issues. Change processes in healthcare are often complex and require learning to adapt to non-linear and unpredictable events.

Objective: This study aims to extend the understanding of the psychological impact of the first-trimester pre-eclampsia (PE) screening on women identified as high risk for preterm PE. We examined the differences between low- vs. high-risk women throughout pregnancy in: symptoms of distress (anxiety, depression, physical and mental health, and worry), health behaviour changes, the experience of pregnancy, and attitudes towards PE screening.

Background: The thymus gland is a lymphoid organ normally located in the anterior mediastinum. Location abnormalities of the thymus, such as ectopic thymus or the superior herniation of a mediastinal thymus, could be responsible for the occurrence of cervical masses in pediatric patients, raising concerns among clinicians. The knowledge of these conditions is essential for a thorough differential diagnosis and for preventing unnecessary invasive procedures.
