Comparison of the role of vitamin D in normal organs and those affected by COVID-19.

The outbreak of COVID-19 has opened up new avenues for exploring the importance of vitamin D in immunity, in addition to its role in calcium absorption. Recently, vitamin D supplementation has been found to enhance T regulatory lymphocytes, which are reduced in individuals with COVID-19. Increased risk of pneumonia and increases in inflammatory cytokines have been reported to be major threats associated with vitamin-D deficiency.

Effective BCDNet-based breast cancer classification model using hybrid deep learning with VGG16-based optimal feature extraction.

Problem: Breast cancer is a leading cause of death among women, and early detection is crucial for improving survival rates. The manual breast cancer diagnosis utilizes more time and is subjective. Also, the previous CAD models mostly depend on manmade visual details that are complex to generalize across ultrasound images utilizing distinct techniques.

Testis-Sparing Approach in Paratesticular Leiomyoma: A Rare Case Navigating From Diagnosis to Targeted Treatment Planning.

In this case study, we describe a 46-year-old male presenting with a palpable, gradually enlarging scrotal mass persisting over three to four years, ultimately diagnosed as paratesticular leiomyoma, who underwent enucleation of the tumor with no signs of recurrence, two years after surgery. This report underscores the significance of accurate diagnosis to avoid unnecessary treatment. We also emphasize the sequential events and findings, supported by relevant literature review, that contributed to establishing the correct diagnosis and guiding appropriate treatment decisions.
