Factors predicting depressive symptoms in parents of children with autism spectrum disorder in eastern China.

BACKGROUND: Parents of children with autism spectrum disorder (ASD) are at a higher risk of depression than parents of typically developing children and those of children with other developmental disorders. Depression affects the well-being and quality of life of parents of children with ASD and has serious consequences for the long-term health outcomes of children with ASD. Therefore, this study explored the current status of depressive symptoms in parents of children with ASD in eastern China and further analyzed multiple aspects of the predictors of depressive symptoms. METHODS: A multicenter cross-sectional survey was conducted among parents of children with ASD in the rehabilitation department of a large specialized hospital and 10 rehabilitation centers for children with special needs in Lianyungang, Jiangsu Province, Eastern China. A structured questionnaire that focused on child-related factors, parent-related factors, depressive symptoms, courtesy stigma, and social support was used to obtain data. Binary logistic regression was used to identify the independent predictors of depressive symptoms in parents of children with ASD. RESULTS: A total of 409 parents of children with ASD were recruited, of whom 18.8% had depressive symptoms. Parents of children with ASD who raised a child who spoke few to no words (odds ratio [OR]: 2.747, 95% confidence interval [CI]: 1.026-7.357), claimed a high economic burden (OR: 3.215, 95% CI: 1.234-8.379), reported no change or increased severity of ASD in their children (OR: 2.518, 95% CI: 1.108-5.720), and those with a higher courtesy stigma score (OR: 1.189, 95% CI: 1.093-1.294) were more likely to have depressive symptoms. Conversely, parents of children with ASD who were employed (OR: 0.427, 95% CI: 0.201-0.907), satisfied with their current marital status (OR: 0.429, 95% CI: 0.221-0.834), and those with a higher social support score (OR: 0.973, 95% CI: 0.950-0.996) were less likely to have depressive symptoms. CONCLUSIONS: Depressive symptoms are common in parents of children with ASD in eastern China. Therefore, screening and intervention for depressive symptoms in parents of children with ASD is necessary, especially for those with high-risk factors.

Novel KMT5B variant associated with neurodevelopmental disorder in a Chinese family: A case report.

Background: We report here the clinical and genetic features of KMT5B-related neurodevelopmental disorder caused by a novel heterozygous frameshift variant in KMT5B in a Chinese family. Case presentation: A 7-year-old Chinese boy with mild-to-moderate intellectual disability, significant language impairment, motor disability, and coordination difficulties presented to our hospital because he "could not speak and did not look at others." He was diagnosed with autism spectrum disorder previously owing to developmental delays in cognition, language expression, and understanding. The child also had variable nonspecific features including macrocephaly, wide button-hole space and nasal bridge, low ear, social behavior disorder, and foot deformities. Exome sequencing (ES) revealed that both the proband and his younger brother had inherited a novel heterozygous frameshift variant c.438_439ins[ASD; KT192064.1:1_310] of the KMT5B gene from their father. Bioinformatics analysis showed that the novel mutation affected the structure of the KMT5B pre-SET domain, mainly in the α-helix region. According to the American College of Medical Genetics and Genomics (ACMG) guidelines, this type of variant was eventually determined to be likely pathogenic (PVS1+PM2_P). Conclusions: Our investigation expands the mutation spectrum of KMT5B to help us to better understand KMT5B-related neurodevelopmental disorder.

Blood nesfatin-1 levels in patients with polycystic ovary syndrome: a systematic review and meta-analysis.

Background: Previous studies have investigated the relationship between nesfatin-1 level and polycystic ovary syndrome (PCOS). However, these studies have produced conflicting results. Thus, in this meta-analysis, we aimed to clarify the association between blood nesfatin-1 levels and PCOS, and the ability of nesfatin-1 as a biomarker in PCOS. Methods: Meta-analysis was performed using STATA 12.0 software. We computed standard mean difference (SMD) and 95% confidence interval (CI) regarding the comparison of blood nesfatin-1 in patients with PCOS and controls. Results: The present meta-analysis showed no significant difference in blood nesfatin-1 level between patients with PCOS and controls with a random effects model (SMD = 0.03; 95%CI: -0.71, 0.77; I2 = 97.1%, p value for Q test < 0.001). Subgroup analysis for different ethnicities reported no significant difference in blood nesfatin-1 level between patients with PCOS and controls in both Caucasian and Asian populations. Subgroup analysis for different sample types reported no significant difference in serum nesfatin-1 level between patients with PCOS and controls. Subgroup studies reported no significant difference in blood nesfatin-1 level between PCOS and controls in both obese and non-obese populations. Conclusion: In conclusion, there is no significant relationship between blood nesfatin-1 levels and PCOS.
