Prevalence of transthyretin cardiac amyloidosis in undifferentiated heart failure with preserved ejection fraction

ESC Heart Failure, Volume 12, Issue 2, Page 1176-1182, April 2025.
Abstract Aims Transthyretin amyloid cardiomyopathy (ATTR‐CM) is an increasinglyrecognized cause of heart failure with preserved ejection fraction (HFpEF), which may be diagnosed non‐invasively using 99mTc 3,3‐diphosphono‐1,2‐propanodicarboxylic acid (DPD) scintigraphy‐based diagnostic criteria.

Left atrial function in uraemic patients: Four‐dimensional automatic left atrial quantitative technology study

ESC Heart Failure, Volume 12, Issue 2, Page 1316-1325, April 2025.
Abstract Objective This study aimed to evaluate the utility of left atrial volume and function in uraemic patients using four‐dimensional automatic left atrial quantification (4D auto LAQ) technology. Methods Thirty‐four undialysed uraemic patients (U‐ND group), 60 dialysed uraemic patients (U‐D group), and 32 healthy volunteers (N group) were enrolled

Venous blood lactate concentration as a predictor of intestinal viability in horses with acquired indirect inguinal hernia

Equine Veterinary Journal, EarlyView.
Abstract Background Acquired indirect inguinal hernia represents a life‐threatening emergency. Therapeutic decision‐making largely depends on intestinal viability, for which specific predictive parameters (such as venous lactate) have not been evaluated.

Development and External Validation of an Efficient Deep Learning Model for Lesion Segmentation and Subtyping of Hepatic Echinococcosis in Ultrasound Imaging

Health Care Science, EarlyView.
We developed a lightweight deep learning framework that integrates frequency‐ and spatial‐domain ultrasound features with segmentation‐assisted classification for hepatic echinococcosis diagnosis. The model outperformed existing state‐of‐the‐art methods in both accuracy and inference speed while requiring substantially fewer computational resources ...

A color Doppler ultrasound-guided protocol for the precise placement of nerve catheters: an anatomical validation study in fresh and fixed cadavers

BMC Anesthesiology
Background Continuous analgesia via peripheral nerve catheters (PNCs) is highly effective but prone to tip malposition. Direct ultrasound-guided localization of the PNC tip remains challenging, and no universal method is currently established.

Anatomical Variation of Absent Facial Vein: Implications for Facial Reanimation Surgery

Head &Neck, EarlyView.
ABSTRACT Background The facial vein is the standard recipient vessel in facial reanimation surgery. Its complete absence is rarely described but may cause major challenges during free functional muscle transfer (FFMT). This study aimed to determine the prevalence and predictors of facial vein absence and assess its surgical relevance in facial ...

Angiogenic and angiostatic factors in renal scleroderma-associated vasculopathy [PDF]

, 2017
BACKGROUND: The angiogenesis in systemic sclerosis (SSc) is impaired. An imbalance of pro-angiogenic factors and angiogenesis inhibitors has been implicated in the progression of peripheral microvascular damage, defective vascular repair and fibrosis ...
