Medical image foundation models in assisting diagnosis of brain tumors: a pilot study
ConclusionsFoundation models obtained from self-supervised learning have demonstrated encouraging potential for scalability and interpretability in downstream brain tumor-related tasks and hold promise for extension to neurological diseases with diffusely distributed lesions.Clinical relevance statementThe application of our proposed method to the prediction of key molecular status in gliomas is expected to improve treatment planning and patient outcomes. Additionally, the foundation model we developed could serve as a cornerstone for advancing AI applications in the diagnosis of brain-related diseases. (Source: European Radiology)

Skin Cancer Image Segmentation Based on Midpoint Analysis Approach
This article introduces an innovative segmentation mechanism that operates on the ISIC dataset to divide skin images into critical and non-critical sections. The main objective of the research is to segment lesions from dermoscopic skin images. The suggested framework is completed in two steps. The first step is to pre-process the image; for this, we have applied a bottom hat filter for hair removal and image enhancement by applying DCT and color coefficient. In the next phase, a background subtraction method with midpoint analysis is applied for segmentation to extract the region of interest and achieves an accuracy of 95...

Efficacy of sentinel lymph-node biopsy after neoadjuvant chemotherapy in clinically axilla node-negative patients
ConclusionsAxillary lymph-node dissection may not be necessary for patients with cNO confirmed by physical and radiological examination using positron emission tomography (PET) computed tomography (CT), and breast magnetic resonance imaging (MRI) after NACT, if ≥ three negative SLNB are removed. Further studies are needed to confirm our findings. (Source: Surgery Today)

Computed Tomography-Based Body Composition is Related to Perioperative Morbidity in Older Lung Transplant Recipients
Conclusion Body composition parameters determined in pretransplant chest CT scans in older LTx candidates might aid in identifying high-risk patients with a worse perioperative outcome after LTx.

A prospective case series to evaluate subcostal nerve injury with high-resolution ultrasound in posterior retroperitoneoscopic adrenalectomy
ConclusionIn this exporatory case series the incidence of postoperative damage to the subcostal nerve, both clinically and radiologically, was 60% after posterior retroperitoneoscopic adrenalectomy. There was no association with pain, and the spontaneous recovery rate was high.Graphical Abstract (Source: Surgical Endoscopy)

Comparison of [18F]FDG and [68 Ga]pentixafor PET/CT in Nasopharyngeal Carcinoma
Conclusions[68 Ga]pentixafor is a promising imaging tracer for detecting primary and metastatic NPC. [68 Ga]pentixafor PET/CT is comparable to [18F]FDG PET/CT in the detection rate of primary tumors and metastatic cervical lymph nodes in nasopharyngeal carcinoma, but [68 Ga]pentixafor uptake was heterogeneous. [68 Ga]pentixafor PET/CT may help select patients most likely to benefit from CXCR4-directed endoradiotherapy.Clinical trial registration No.: ChiCTR2200065902 (Source: Molecular Imaging and Biology)

Healing the Miseducation About Pressure Injuries and Chronic Wounds
My great aunt was a career US Air Force nurse who served during World War II. I was in medical school when I encountered my first patient with a pressure injury, and I have a vivid memory of her reaction when I told her about it. She was quite literally shocked, sharing that it would have been scandalous if an injured airman or soldier developed a pressure injury. She said it would have been considered a failure of care. Because most pressure injuries today occur in older adults who often are frail, have multiple chronic conditions and limited mobility, that viewpoint has evolved, and I while I don ’t believe most expert...
