Noradrenaline release from the locus coeruleus shapes stress-induced hippocampal gene expression.

Exposure to an acute stressor triggers a complex cascade of neurochemical events in the brain. However, deciphering their individual impact on stress-induced molecular changes remains a major challenge. Here, we combine RNA sequencing with selective pharmacological, chemogenetic, and optogenetic manipulations to isolate the contribution of the locus coeruleus-noradrenaline (LC-NA) system to the acute stress response in mice.

Brain Kynurenine Pathway Metabolite Levels May Reflect Extent of Neuroinflammation in ALS, FTD and Early Onset AD.

Objectives: Despite distinct clinical profiles, amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD) patients share a remarkable portion of pathological features, with a substantial percentage of patients displaying a mixed disease phenotype. Kynurenine metabolism seems to play a role in dementia-associated neuroinflammation and has been linked to both diseases. We aimed to explore dissimilarities in kynurenine pathway metabolites in these early onset neurodegenerative disorders in a brain-region-specific manner.

Plasma 5-HIAA activity indicative of serotonergic disturbances in cognitively impaired, elderly patients experiencing postoperative delirium.

Objectives: Delirium frequently arises in older demented and non-demented patients in postoperative, clinical settings. To date, the underlying pathophysiological mechanisms remain poorly understood. Monoamine neurotransmitter alterations have been linked to delirium and cognitive impairment.

Differentiating Colorectal Carcinoma From Diverticulitis With Computerised Tomography: Does Every Patient Need Follow-Up Colonoscopy After an Episode of Acute Diverticulitis?

Purpose To correlate computerised tomography (CT) and endoscopic follow-up (FU) in differentiating presentations of acute diverticulitis (AD) and colorectal carcinoma (CRC). Methods Patient's discharge summaries between April 2018 and September 2019, stating AD under-diagnosis were retrieved. Admission details, CT reports, endoscopic findings and histopathology results were retrospectively collected from prospectively maintained data.

Early integrated palliative care in chronic heart failure and chronic obstructive pulmonary disease: protocol of a feasibility before-after intervention study.

Background: Patients with chronic heart failure (CHF) and patients with chronic obstructive pulmonary disease (COPD) are amenable to integrated palliative care (PC); however, despite the recommendation by various healthcare organizations, these patients have limited access to integrated PC services. In this study, we present the protocol of a feasibility prospective study that aims to explore if an "early integrated PC" intervention can be performed in an acute setting (cardiology and pulmonology wards) and whether it will have an effect on (i) the satisfaction of care and (ii) the quality of life and the level of symptom control of CHF/COPD patients and their informal caregivers.

Methods: A before-after intervention study with three phases, (i) baseline phase where the control group receives standard care, (ii) training phase where the personnel is trained on the application of the intervention, and (iii) intervention phase where the intervention is applied, will be carried out in cardiology and pulmonology wards in the University Hospital Leuven for patients with advanced CHF/COPD and their informal caregivers.
