AI Article Synopsis

  • A 70-year-old male was admitted with chest pain and faintness, showing signs on an ECG that suggested his pacemaker wasn't capturing his heartbeats properly.
  • Further testing, including a 12-lead ECG and a device interrogation, indicated that what appeared to be non-capture was actually a false indication (pseudo non-capture).
  • The device interrogation confirmed that the pacemaker was effectively capturing the ventricles as intended.

Article Abstract

This case report presents a 70-year-old-male, brought in by ambulance for assessment of chest pain and presyncope, with a paced ECG showing possible non-capture following ventricular pacing spikes. This was demonstrated to be pseudo non-capture with a 12-lead electrocardiogram performed in emergency and a device interrogation demonstrating ventricular capture.

Summary: Oral levothyroxine (LT4) is prescribed worldwide for hypothyroidism. Bariatric surgery for patients with obesity has shown a substantial, long-term weight loss and considerable improvement of obesity-related diseases. LT4 malabsorption represents a significant cause of refractory hypothyroidism, well known after malabsorptive bariatric surgery such as Roux-en-Y gastric bypass.

Neonatal pseudo-hypoaldosteronism type 1 with a novel gene variant.

Sudan J Paediatr

Pseudohypoaldosteronism (PHA) is a rare disorder that mimics congenital adrenal hyperplasia (CAH). Renal type A1A of the disorder has a known gene mutation (NR3C2) and parents may be asymptomatic despite biochemical abnormalities. Meticulous interpretation of hormonal and biochemical data, and early liaison with endocrinology and renal teams are key in diagnosis.

With the rapid development of tourism, the concentration of visitor flows poses significant challenges for public safety management, especially in low-light and highly occluded environments, where existing pedestrian detection technologies often struggle to achieve satisfactory accuracy. Although infrared images perform well under low-light conditions, they lack color and detail, making them susceptible to background noise interference, particularly in complex outdoor environments where the similarity between heat sources and pedestrian features further reduces detection accuracy. To address these issues, this paper proposes the FusionU10 model, which combines information from both infrared and visible light images.

Human adipose depots are functionally distinct. Yet, recent single-nucleus RNA sequencing (snRNA-seq) analyses largely uncovered overlapping or similar cell-type landscapes. We hypothesized that adipocyte subtypes, differentiation trajectories and/or intercellular communication patterns could illuminate this depot similarity-difference gap.

Simultaneous Treatment of Pseudo-gynecomastia and Lateral Chest in Patients with Massive Weight Loss.

Aesthetic Plast Surg

January 2025

Department of Plastic, Burn and Maxillofacial Surgery, Ain Shams University, 7 Mohsen Roshdy street, Nasr City, Cairo, 11731, Egypt.

Background: Pseudogynecomastia in MWL patients is characterized by excess skin in chest, lateral chest, axilla and upper abdomen without enlargement of the breast glandular component. The aim of this work was to study long-term aesthetic outcomes of correction of severe pseudogynecomastia post-weight loss with inferior pedicle technique with some refinements.

Methodology: This prospective study included 15 patients underwent chest contouring after massive weight loss within period of 2 years between January 2022 and January 2024.
