Objectives: To test whether presenilin-1 E280A mutation carriers have reduced basal forebrain functional connectivity and whether this is linked to amyloid pathology.

Long-term Mechanical Circulatory Support in Cardiogenic Shock Secondary to Acromegaly. Case report.

Heart failure is a complication that may develop in patients diagnosed with acromegaly. This complication can progress to cardiogenic shock, which in cases like the one described, may be refractory to optimal medical management, necessitating the use of mechanical circulatory support as a bridge to decision. Given the specific morphology of this patient's heart, the likelihood of finding a suitable donor in our environment was very low.

First evidence of human infection by the kinetoplastid flagellate Dimastigella trypaniformis in a patient with urinary tract infection.

We present a case of an 88-year-old man with symptoms consistent with a urinary tract infection, whose diagnostic workup uncovered a previously unrecognized motile flagellated protozoan. Molecular identification confirmed the organism as Dimastigella trypaniformis, a free-living kinetoplastid from the Rhynchomonadidae family. Known only from soil samples in Scotland and termite gut contents in Australia and Germany, Dimastigella trypaniformis has not been previously reported to infect vertebrate hosts.

Clinical presentation of pheochromocytoma and screening recommendations.

Pheochromocytomas are neuroendocrine tumors that derive from sympathetic adrenomedullary chromaffin tissue and produce catecholamines. Due to the excess release of catecholamines, they can produce arterial hypertension, tachycardia, sweating, headache and a large number of other clinical manifestations secondary to the stimulation of α and β adrenoreceptors. Screening for pheochromocytoma is recommended in patients with paroxysmal, resistant or early-onset arterial hypertension, in cases with symptoms suggestive of catecholamine hypersecretion, patients with hereditary syndromes associated with pheochromocytomas, diabetes mellitus of atypical presentation and in adrenal incidentalomas with radiological characteristics not typical of adenoma (with > 10 Hounsfield Units on non-contrast CT).

Transhepatic venous access for catheter ablation of right and left side atrial arrhythmias in adults: challenges and outcomes.

Introduction: Electrophysiologic (EP) procedures are typically performed via the femoral venous system, but in some patients, the inferior vena cava (IVC) is unavailable. The hepatic vein has emerged as a viable alternative to femoral access, providing an inferior route that accommodates large sheaths required for better catheter manipulation. Although the percutaneous transhepatic approach has been used successfully in the pediatric population, its use in adults is scarce, with a complication rate of approximately 5%.

Intranasal oxytocin for apathy in people with frontotemporal dementia (FOXY): a multicentre, randomised, double-blind, placebo-controlled, adaptive, crossover, phase 2a/2b superiority trial.

Background: No treatments exist for apathy in people with frontotemporal dementia. Previously, in a randomised double-blind, placebo-controlled, dose-finding study, intranasal oxytocin administration in people with frontotemporal dementia improved apathy ratings on the Neuropsychiatric Inventory over 1 week and, in a randomised, double-blind, placebo-controlled, crossover study, a single dose of 72 IU oxytocin increased blood-oxygen-level-dependent signal in limbic brain regions. We aimed to determine whether longer treatment with oxytocin improves apathy in people with frontotemporal dementia.
