Abstract: Background: Aging brains are shaped by a continuous dialogue amongst diminishing neurogenesis as well as escalating neuroinflammation. Neural stem cells propagatively possess elimination of regenerative capability, whereas microglia in addition to astrocytes switch toward maladaptive states that undermines synaptic plasticity, along with cognition. Such intersecting defines inflammaging, a gradual however unrelenting event that weaken flexibility. Nevertheless, the field continues to be hindered by pivotal lacunae: i) incomplete mapping of microglial multifaceted nature, ii) lack of insight over epigenetic scars frominflammasome signaling, iii) absence of longitudinal data, iv) unclear niche-particular immune mechanistic modes, as well as v) uncertain cross-species germaneness. This review tackles such pressing barricades, with the objective of conversion of fractionated understanding into actionable approaches. Summary: We chart the manner neurogenesis in addition to neuroinflammation operate in persistent dialogue, isolate five major information lacunae, along with explore approaches to reprogram such crosstalk. Strategies are inclusive of i) longitudinal imaging, ii) niche-focused immunomodulation, iii) glial subtype reprogramming, iv) brain-penetrant inflammasome hampering agents, as well as v) CRISPR- dependent epigenetic editing.Every approach is mapped against i) translational plausibility, ii) short-term feasibility, in addition to iii) long term vision, with highlighting the manner mechanistic exactitude possesses the capability of driving clinical breakthrough. Conclusions: Here we emphasize that neurogenic plausibility is not completely eliminated however might be perpetuated or cause restoration by recalibrating immune along with epigenetic milieu. This review posits a roadmap for reshaping the aging brain’s fate, yielding mechanistically grounded approaches to postpone cognitive diminishing. Further than neurology, the work butresses a wider principle: by incorporating cellular plasticity with immune modulation, science edges nearer to re-engineeringflexibility across the lifespan.

Abstract: The maternal pelvis is a unique osteoligamentous structure that plays a fundamental role in normal vaginal delivery. While obstetric practice primarily focuses on maternal and fetal factors influencing labor, orthopedic understanding of pelvic anatomy, biomechanics, joint mobility, and pelvic morphology is equally important. The bony pelvis serves as the birth canal, and its dimensions, shape, orientation, and dynamic adaptations determine the ease with which the fetal head traverses the pelvic inlet, cavity, and outlet. Although true cephalopelvic disproportion (CPD) is relatively uncommon, abnormalities of pelvic architecture resulting from congenital deformities, trauma, metabolic bone disease, hip disorders, or previous pelvic fractures may significantly influence labor outcomes. Recent evidence suggests that routine pelvimetry alone is a poor predictor of successful vaginal delivery. Modern obstetrics increasingly relies on dynamic assessment through clinical examination and intrapartum ultrasound rather than static measurements. Nevertheless, orthopedic evaluation remains valuable in women with previous pelvic injuries, skeletal dysplasia, acetabular abnormalities, or pelvic reconstructive surgery. This review summarizes pelvic anatomy, biomechanics, orthopedic conditions affecting childbirth, methods of pelvic assessment, and current evidence regarding delivery planning from an orthopedic perspective.
