Surgery and the first 8000 days of life: a review.

The first 8000 days of life, from birth to adulthood, encompasses critical phases that shape a child's health and development. While global health efforts have focused on the first 1000 days, the next 7000 days (ages 2-21) are equally vital, especially concerning the unmet burden of surgical conditions in low- and middle-income countries (LMICs).

Delivery of Safe Pediatric Anesthesia Care in the First 8000 days: Realities, Challenges, and Solutions in Low- and Middle-Income Countries.

Background: Worldwide, perioperative mortality has declined over the past 50 years, but the reduction is skewed toward high-income countries (HICs). Currently, pediatric perioperative mortality is much higher in low- and middle-income countries (LMICs) compared to HICs, despite studied cohorts being predominantly low-risk. These disparities must be studied and addressed.

Targeted ablation of the PTH/PTHrP receptor in osteocytes impairs bone structure and homeostatic calcemic responses.

Parathyroid hormone (PTH) is a major physiologic regulator of calcium, phosphorous, and skeletal homeostasis. Cells of the osteoblastic lineage are key targets of PTH action in bone, and recent evidence suggests that osteocytes might be important in the anabolic effects of PTH. To understand the role of PTH signaling through the PTH/PTHrP receptors (PPR) in osteocytes and to determine the role(s) of these cells in mediating the effects of the hormone, we have generated mice in which PPR expression is specifically ablated in osteocytes.

SloR modulation of the Streptococcus mutans acid tolerance response involves the GcrR response regulator as an essential intermediary.

Streptococcus mutans, the primary causative agent of human dental caries, grows as a biofilm on the tooth surface, where it metabolizes dietary carbohydrates and generates acid byproducts that demineralize tooth enamel. A drop in plaque pH stimulates an adaptive acid-tolerance response (ATR) in this oral pathogen that allows it to survive acid challenge at pHs as low as 3.0.
