Abstract We explored the association between the serum level of cystatin C (CysC) at admission and short‐term functional outcome in patients with hypertensive intracerebral hemorrhage (HICH) without chronic kidney disease (CKD). A total of 555 patients with HICH were consecutively recruited after admission and were followed‐up for 3 months after admission. The primary outcome was poor functional outcome (modified Rankin Scale [mRS] score ≥ 3). The median serum CysC level in our cohort was 1.03 mg/L (interquartile range, .89–1.20). Patients were categorized into four groups according to the serum CysC quartiles. Multivariate logistic regression analysis revealed a negative association between serum CysC and poor functional outcome at 3‐month follow‐up (quartile [Q]1 vs. Q4: adjusted odds ratio [OR] = .260, 95% confidence interval [CI] = .098, .691, p < .001). The negative association between serum CysC and poor functional outcome at 3 months was more pronounced in subgroups with smaller hematoma volume (≤ 30 mL), and absence of secondary intraventricular hemorrhage (IVH). Addition of serum CysC to a model containing conventional risk factors improved the model performance with net reclassification index (NRI) of .426% (p < .001) and integrated discrimination improvement (IDI) of .043% (p < .001) for poor functional outcome. Serum CysC was found to be a negative predictor of poor short‐term functional outcome in HICH patients independent of renal function.

Background The incidence of delay language development in early childhood is high, and the early recognition rate is low, which has a significant negative impact on the early childhood development of other dimensions. The family cognitive environment is a key factor affecting early childhood language development. Objective This study aimed to explore the influence of family cognitive environment on early childhood language development, and provide theoretical basis for promoting early childhood language development from the perspective of community intervention on family cognitive environment. Methods A retrospective case-control study was conducted on 4 307 children who were admitted to a community child healthcare department in Shanghai from 2018 to 2020. The Shanghai Pediatric Development Screening Scale Ⅱ (DenverⅡ) was used for developmental screening, which was conducted at the child's age of 1, 2, and 3 years old. A total of 172 children with delay language development were selected as the case group, and 516 children with normal language development were included in the control group, which was determined by the matching factor of age, with a ratio of the number of children in the case and control groups being 1∶3. The following information of children in both groups were collected, including children's basic birth characteristics, parental demographic characteristics, maternal pregnancy and childbirth characteristics, and family cognitive environment characteristics. The Logistic regression analysis was used to explore the influencing factors of delay early childhood language development. Results A total of 172 children with delayed early language development had an incidence rate of 3.99%, among them ,1-year-old, 2-year-old, and 3-year old children accounted for 33.14% (57 cases), 53.49% (92 cases), and 13.37% (23 cases), respectively. The proportions of male children, children with premature birth, and children with maternal education of high school and below were higher in the case group than those in the control group (P
