Article Abstract
Central precocious puberty (CPP) is associated with adverse health outcomes in females; however, CPP pathogenesis remains unclear. In this study, we investigated the association of 20 single nucleotide polymorphisms (SNPs) in eight genes with CPP risk and hormone levels. A case-control study on 247 and 243 girls with and without CPP, respectively, was conducted at Kunming Children's Hospital, China, from September 2019 to August 2020. The genotype of the SNPs and their haplotypes were identified. Additionally, the effects of the polymorphisms on hormone levels were investigated. Three variants (rs10159082, rs7538038, and rs5780218) in and two variants (rs7895833 and rs3758391) in were related to an increased CPP risk (odds ratio (OR) = 1.524, 1.507, 1.409, 1.348, and 1.737; 95% confidence interval (CI) = 1.176-1.974, 1.152-1.970, 1.089-1.824, 1.023-1.777, and 1.242-2.430, respectively). Rs3740051in and rs1544410 in reduced CPP risk (OR = 0.689, 0.464; 95% CI, 0.511-0.928, 0.232-0.925, respectively). Rs1544410, rs7975232, and rs731236 in were negatively correlated with peak follicle-stimulating hormone (FSH; = -2.181; =0.045), basal FSH ( = -0.391; =0.010), and insulin-like growth factor ( = -50.360; =0.041) levels, respectively. , , and variants were associated with CPP susceptibility, and SNPs influenced hormonal levels in Chinese females with CPP. In particular, polymorphism rs1544410 was associated with both CPP risk and GnRH-stimulated peak FSH levels. Further functional research and large-scale genetic studies of these loci and genes are required to confirm our findings.

Importance: Higher intellectual abilities have been associated with lower mortality risk in several longitudinal cohort studies. However, these studies did not fully account for early life contextual factors or test whether the beneficial associations between higher neurocognitive functioning and mortality extend to children exposed to early adversity.
Objective: To explore how the associations of child neurocognition with mortality changed according to the patterns of adversity children experienced.

Background: Low cerebral perfusion pressure (CPP) has previously been identified as a key prognostic marker after pediatric traumatic brain injury (TBI). Cerebrovascular autoregulation supports stabilization of cerebral blood flow within the autoregulation range. Beyond the upper limit of this range, cerebral blood flow increases with increasing CPP, leading to increased risk of intracranial hypertension and blood-brain barrier disruptions.

Di(2-ethylhexyl) phthalate (DEHP), the most prevalent plasticizer worldwide, can enter the human body via various exposure pathways, including ingestion, inhalation, skin contact, and medical applications. It has been observed to exhibit characteristic patterns of accumulation in the female reproductive system. Research has demonstrated that DEHP poses a threat to reproductive health in females across various life stages.

Central precocious puberty (CPP) results from premature reactivation of the hypothalamic-pituitary-gonadal axis and is increasingly recognized as a systemic condition linked to cardiometabolic health. Genetic mutations, particularly in imprinted genes such as and , are major monogenic causes of familial CPP, while rare activating variants in and highlight the pivotal role of kisspeptin signaling. Neuropeptides, including kisspeptin and neurokinin B, are central to pubertal regulation.
