(TW) is a rod-shaped, gram-positive bacterium that, when chronically infects humans, can lead to multi-system pathologies, including joint pain, abdominal pain with diarrhea and weight loss, myocarditis, pericarditis, and neurologic inflammation. Moreover, acute infections can lead to bronchopulmonary infections, bacteraemia, and acute diarrhea. However, fewer cases of acute pneumonia due to TW have been reported, and this diagnosis is not well founded. Herein, we report a case of acute pneumonia caused by a TW infection. The patient, a middle-aged man, underwent bronchoscopic alveolar lavage, and the metagenomic next-generation sequencing of the lavage fluid suggested TW infection. A lung puncture biopsy tissue specimen was also positive based on periodic acid-Schiff staining. After confirming the diagnosis, the patient was administered ceftriaxone for anti-infection treatment, improving clinical symptoms and lung imaging results. Therefore, in cases where conventional anti-infective treatment is ineffective for patients with acute pneumonia, we should consider the possibility of TW infection, conduct prompt pathogenetic examination, and provide timely treatment after diagnosis to improve overall patient prognosis.

Acute kidney injury in critically ill COVID-19 patients in a tertiary hospital: short and long-term kidney and patient outcomes.
J Bras Nefrol
January 2025
Santa Casa de Porto Alegre, Porto Alegre, RS, Brazil.
Introduction: Acute kidney injury (AKI) in the setting of COVID-19 is associated with worse clinical and renal outcomes, with limited long-term data.
Aim: To evaluate critically ill COVID-19 patients with AKI that required nephrologist consultation (NC-AKI) in a tertiary hospital.
Methods: Prospective single-center cohort of critically ill COVID-19 adult patients with NC-AKI from May 1st, 2020, to April 30th, 2021.
Disseminated organ and tissue infection secondary to carbapenem-resistant Klebsiella pneumoniae bloodstream infection for acute lymphoblastic leukemia treated with ceftazidime-avibactam: Two case reports.

Rationale: Carbapenem-resistant Klebsiella pneumoniae (CRKP) bloodstream infections are a severe complication resulting from granulocyte deficiency following chemotherapy for hematologic malignancies and have a high mortality rate. However, reports of disseminated organ infections secondary to bloodstream infections are rare.
Patient Concerns And Diagnoses: We report 2 cases of patients with acute lymphoblastic leukemia who both developed CRKP bloodstream infections during the granulocyte deficiency stage following chemotherapy, with 1 case of secondary bacterial liver abscess and 1 case of secondary septic arthritis.
Ultrasensitive detection of intact SARS-CoV-2 particles in complex biofluids using microfluidic affinity capture.

Measuring virus in biofluids is complicated by confounding biomolecules coisolated with viral nucleic acids. To address this, we developed an affinity-based microfluidic device for specific capture of intact severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Our approach used an engineered angiotensin-converting enzyme 2 to capture intact virus from plasma and other complex biofluids.

The underlying mechanisms explaining the differential course of SARS-CoV-2 infection and the potential clinical consequences after COVID-19 resolution have not been fully elucidated. As a dysregulated mitochondrial activity could impair the immune response, we explored long-lasting changes in mitochondrial functionality, circulating cytokine levels, and metabolomic profiles of infected individuals after symptoms resolution, to evaluate whether a complete recovery could be achieved. Results of this pilot study evidenced that different parameters of aerobic respiration in lymphocytes of individuals recuperated from a severe course lagged behind those shown upon mild COVID-19 recovery, in basal conditions and after simulated reinfection, and they also showed altered glycolytic capacity.

Hypoxia-inducible factors (HIFs) are central regulators of gene expression in response to oxygen deprivation, a common feature in critical illnesses. The significant burden that critical illnesses place on global healthcare systems highlights the need for a deeper understanding of underlying mechanisms and the development of innovative treatment strategies. Among critical illnesses, impaired lung function is frequently linked to hypoxic conditions.
