Abstract Objective To test the reliability and validity of the Chinese version of the Child-to-parent Violence Questionnaire (CPV-Q) in a group of Chinese adolescents. Methods A total of 1138 adolescents (15.24 ± 1.17 years old) were tested with the Chinese version of CPV-Q, Parent-Adolescent Conflict Scale, and Adolescent Aggressive Behavior Scale of which 201 adolescents were retested 1 month later. The Chinese version of CPV-Q contains psychological, physical, financial, and control/domain factors with 14 items. Results The four-factor model has good main fit indicators (father: χ 2 /df = 3.28, CFI = 0.96, RMSEA = 0.06; mother: χ 2 /df = 3.30, CFI = 0.96, RMSEA = 0.06); the scale has good criterion-related validity. The Cronbach’s α coefficients of the Chinese version of CPV-Q were 0.89 (father) and 0.88 (mother), and the Cronbach’s α coefficients of the four subscales were 0.81 ~ 0.84 (father) and 0.76 ~ 0.85 (mother). The test–retest reliability of the Chinese version of CPV-Q was 0.85 (father) and 0.83 (mother), and the test–retest reliability of the four subscales was 0.80 ~ 0.83 (father) and 0.75 ~ 0.84 (mother). Conclusion Therefore, the CPV-Q has good reliability and validity for Chinese adolescents and can be used as an effective tool to evaluate Chinese adolescents’ violence toward their parents.

TTMV::RARA is a recently reported fusion gene associated with acute promyelocytic leukemia (APL), caused by the integration of torque teno mini virus (TTMV) genomic fragments into the second intron of the RARA gene. Currently, there have been only six documented cases, with clinical presentations showing significant variability. Although initial responses to all-trans retinoic acid (ATRA) treatment may be observed in patients with TTMV::RARA-APL, the overall prognosis remains unfavorable among infrequent reported cases. This article presents a pediatric case that manifested as PML::RARA-negative APL with central nervous system involvement at onset. The patient experienced both intramedullary and extramedullary relapse one year after undergoing allogeneic hematopoietic stem cell transplantation. Upon identification as TTMV::RARA-APL and subsequent administration of two rounds of ATRA-based treatment, the patient rapidly developed multiple RARA ligand-binding domain mutations and demonstrated extensive resistance to ATRA and various other therapeutic interventions. Additionally, the patient experienced ARID1A mutant clone expansion and progressed MYC-targeted gene activation. This case represents the first documentation of extramedullary involvement at both the initial diagnosis and relapse stages, emphasizing the intricate clinical features and challenges associated with the rapid accumulation of multiple ATRA-resistant mutations in TTMV::RARA-APL, characterizing it as a distinct and complex sub-entity of atypical APL.

ObjectiveSome previous studies have suggested a potential link between stroke and gastroesophageal reflux disease (GERD). We used a two-sample bidirectional Mendelian randomization (MR) method to explore the causal relationship between stroke and GERD.DesignSummary-level data derived from the published genome-wide association studies (GWAS) were employed for analyses. Single-nucleotide polymorphisms (SNPs) as instrumental variables (IVs) for stroke (n = 446,696) and its common subtypes ischemic stroke (IS) (n = 440,328), large vessel stroke (LVS) (n = 410,484), small vessel stroke (SVS) (n = 198,048), and cardioembolic stroke (CES) (n = 413,304) were obtained from the MEGASTROKE consortium. The data on intracerebral hemorrhage (ICH) (n = 721,135) come from the UK Biobank. Instrumental variables (IVs) for lacunar stroke (LS) (n = 474,348) and GERD (n = 602,604) were screened from publicly available genetic summary data. The inverse variance weighted (IVW) method was used as the main MR method. Pleiotropy was detected by the MR-Egger intercept test, MR pleiotropy residual sum and outlier, and leave-one-out analysis. Cochran Q statistics were used as supplements to detect pleiotropy.ResultsWe found that GERD can causally increase the risk of stroke [IVW odds ratio (OR): 1.22, 95% confidence interval (CI): 1.13–1.32, p = 1.16 × 10−6] and its common subtypes IS (OR: 1.19, 95% CI: 1.10–1.30, p = 3.22 × 10−5), LVS (OR: 1.49, 95% CI: 1.21–1.84, p = 1.47 × 10−4), and LS (OR: 1.20, 95% CI: 1.001–1.44, p = 0.048). Several important risk factors for stroke have also been implicated in the above causal relationship, including type 2 diabetes, sleep apnea syndrome, high body mass index, high waist-to-hip ratio, and elevated serum triglyceride levels. In reverse MR analysis, we found that overall stroke (OR: 1.09, 95% CI: 1.004–1.19, p = 0.039) and IS (OR: 1.10, 95% CI: 1.03–1.17, p = 0.007) have the causal potential to enhance GERD risk.ConclusionThis MR study provides evidence supporting a causal relationship between GERD and stroke and some of its common subtypes. We need to further explore the interconnected mechanisms between these two common diseases to better prevent and treat them.
