  • Most vitamin D is synthesized in the skin from sunlight, with a small percentage obtained from food; it's crucial for bone health and immune function.
  • The study analyzed maternal vitamin D levels during pregnancy and their effects on fetal growth, finding that while hematologic and serological impacts were minimal, vitamin D levels were linked to increased femur and humerus lengths in the fetus.
  • The research suggests maternal vitamin D may help reduce rates of sexually transmitted infections and is important for fetal bone development, highlighting the need for vitamin D sufficiency through diet or sunlight exposure.

We performed the core needle biopsy of metastatic sites and confirmed discordance in estrogen receptor, progesterone receptors, and human epidermal growth factor receptor 2 expression between primary breast cancer and skeletal muscle metastases.
