Postmortem histological freeze-thaw artifacts: a case report of a frozen infant and literature review.

Freezing and thawing have the potential to alter the gross and histologic appearance of tissues, causing damage to individual cells and disrupting the overall architecture. In forensic investigations, freezing and thawing can play a crucial role in cases of unknown cause of death. Perpetrators may use freezing preservation to conceal the body or obscure the time of death.

Impact of COVID-19 outbreak on ICU nurses' mental health. An Italian multicenter study.

Aim: AIM: The aim of this study was to evaluate variations in ICU nurses ' mental health status over the COVID-19 outbreak by quantifying the extent of symptoms of depression, anxiety and PTSD over time.

Results: RESULTS: A total of 359 nurses, 233 (64.

Active screening of COVID-19-associated pulmonary aspergillosis with serum beta-glucan and endotracheal aspirates galactomannan and fungal culture.

Background: Since February 2021 active screening of COVID-19-associated pulmonary aspergillosis (CAPA) has been implemented in our institution.

Objectives: To evaluate CAPA incidence in our centre and evaluate performance of our screening protocol.

Methods: We screened once per week, collecting endotracheal aspirates for fungal culture and galactomannan (GM) and serum for 1,3-ß-D-glucan (BG).

Fulminant Sepsis and Perinatal Death at 23 Weeks Due to .

is a gram-negative anaerobe, a constituent of the oral microflora, responsible for chronic periodontal diseases. We describe a preterm infant with premature rupture of membranes at 23 weeks of gestational age due to . The newborn died soon after birth.

Frontoparietal network activation is associated with motor recovery in ischemic stroke patients.

Strokes cause lesions that damage brain tissue, disrupt normal brain activity patterns and can lead to impairments in motor function. Although modulation of cortical activity is central to stimulation-based rehabilitative therapies, aberrant and adaptive patterns of brain activity after stroke have not yet been fully characterized. Here, we apply a brain dynamics analysis approach to study longitudinal brain activity patterns in individuals with ischemic pontine stroke.
