تشير أبحاث جديدة إلى أن النساء اللواتي يعانين من نقص فيتامين د يواجهن ألماً أكبر بكثير وحاجة متزايدة لاستخدام المسكنات الأفيونية بعد جراحة سرطان الثدي. ووجدت الدراسة أن المريضات اللواتي يعانين من نقص الفيتامين كن أكثر عرضة بثلاث مرات للشعور بانزعاج متوسط إلى شديد في اليوم الأول بعد استئصال الثدي.

تابع باحثون في مستشفى جامعة الفيوم في مصر 184 امرأة كن يستعددن لإجراء عملية استئصال جذري معدل لثدي واحد. أجريت الدراسة الرصدية الاستباقية في الفترة من سبتمبر 2024 حتى أبريل 2025. كانت مستويات فيتامين د لدى نصف المشاركات أقل من 30 نانومول/لتر، بينما كانت المستويات لدى الأخريات كافية. ولم يكن الطاقم الطبي على علم بهذه النتائج أثناء تقديم الرعاية.

A study published in the journal *Bone Research* reports that parathyroid hormone (PTH) reduced pain-related behaviors in mouse models of spinal degeneration, apparently by strengthening vertebral endplates and triggering bone-cell signals that repel pain-sensing nerve fibers. The work was led by Dr. Janet L. Crane of Johns Hopkins University School of Medicine.

Large VIVID trial finds high-dose vitamin D3 did not lessen acute COVID-19 severity, but adherence analysis suggests possible long COVID signal

A major randomized trial led by Mass General Brigham found that a four-week course of high-dose vitamin D3 started soon after a positive COVID-19 test did not reduce acute illness severity, healthcare visits or deaths, and did not curb household spread. But in an analysis limited to participants who consistently took the assigned pills, researchers observed a small, borderline statistically significant difference in lingering symptoms reported eight weeks after infection, a finding they say warrants further study.

Higher midlife vitamin D levels linked to lower brain tau protein

A new study has found that adults with higher vitamin D levels in their 30s and 40s tend to have lower levels of tau protein in their brains about 16 years later. Tau is a key biomarker associated with dementia. The research, published this week, highlights a potential modifiable risk factor for brain health.

A 59-year-old woman achieved remission from a cancerous arm tumor without further treatment after a diagnostic biopsy. The procedure appears to have sparked an immune response that eliminated the myxofibrosarcoma within weeks. This marks one of only nine known similar cases.
