Traumatic injury can result not only in physical disability but also in mental and behavioral sequelae. It is very important to properly judge the severity of disability as well as the need for assistance and future medical treatment. It is very difficult to establish objective guidelines for assessing mental and behavioral disabilities due to the inherent peculiarity of the disabilities. This study uses reports generated for court because they need to be more judicious than reports for other types of evaluation. We analyzed reports concerning the facts and problems associated with evaluation of mental and behavioral disabilities. We hope this study will help further our understanding of mental and behavioral disabilities.

PURPOSE: The purpose of this study was to elucidate prognostic factors for survival and clinical outcomes of rological soft tissue sarcomas (STSs). MATERIALS AND METHODS: This was a retrospective review of the medical records of 48 patients with urological STS treated from January 1982 to July 2009. Demographic and pathological characteristics were compared. Patients' demographics, clinico-pathological parameters, overall survival, and the factors expected to predict survival, such as sex, age at diagnosis, primary organ, surgical resection, metastasis, and mass size, were analyzed. We evaluated differences in survival on the basis of histological subtype by Kaplan-Meier analysis and multivariate Cox proportional hazards regression. RESULTS: The study included 34 males (70.8%) and 14 females (29.1%). The mean age at diagnosis was 47.1 years (range, 3 to 80). The most common site was the retroperitoneum (n=16), followed by the kidney (n=12), prostate (n=10), bladder (n=7), ureter (n=1), and paratesticular region (n=1). Nineteen patients (39.5%) had other organ metastases at diagnosis. The most common subtypes of sarcoma were leiomyosarcoma (50%), rhabdomyosarcoma (18.7%), and liposarcoma (8%). The remaining 11 cases had other histological subtypes (22.9%). Mean tumor size was 9.5 cm (range, 2.2 to 24). Thirty-three patients (68.7%) underwent surgical resection. The overall survival rate at 5 years was 51.4%. In the univariate and multivariate analysis, surgical resection, primary tumor site, and metastasis at diagnosis remained significant predictors of prognosis. Patients with retroperitoneal sarcoma had a higher overall survival rate by 5 years compared with patients with other organ sarcoma. CONCLUSIONS: The overall survival rate at 5 years was 51.4%. Surgical resection, primary tumor site, and metastasis at diagnosis remained significant predictors of prognosis.

Background/Aims: Blocking the complement system is a promising strategy to impede the progression of metabolic dysfunction–associated steatotic liver disease (MASLD). However, the interplay between complement and MASLD remains to be elucidated. This comprehensive approach aimed to investigate the potential association between complement dysregulation and the histological severity of MASLD. Methods: Liver biopsy specimens were procured from a cohort comprising 106 Korean individuals, which included 31 controls, 17 with isolated steatosis, and 58 with metabolic dysfunction–associated steatohepatitis (MASH). Utilizing the Infinium Methylation EPIC array, thorough analysis of methylation alterations in 61 complement genes was conducted. The expression and methylation of nine complement genes in a murine MASH model were examined using quantitative RT-PCR and pyrosequencing. Results: Methylome and transcriptome analyses of liver biopsies revealed significant (p<0.05) hypermethylation and downregulation of C1R, C1S, C3, C6, C4BPA<, and SERPING1, as well as hypomethylation (p<0.0005) and upregulation (p<0.05) of C5AR1, C7, and CD59, in association with the histological severity of MASLD. Furthermore, DNA methylation and the relative expression of nine complement genes in a MASH diet mouse model aligned with human data. Conclusions Our research provides compelling evidence that epigenetic alterations in complement genes correlate with MASLD severity, offering valuable insights into the mechanisms driving MASLD progression, and suggests that inhibiting the function of certain complement proteins may be a promising strategy for managing MASLD.

Colorectal cancer (CRC) is the second most common cause of cancer-related death in the world. The pro-viral integration site for Moloney murine leukemia virus 1 (PIM1) is a proto-oncogene and belongs to the serine/threonine kinase family, which are involved in cell proliferation, migration, and apoptosis. Fibroblast growth factor receptor 1 (FGFR1) is a tyrosine kinase that has been implicated in cell proliferation, differentiation and migration. Small molecule HCI-48 is a derivative of chalcone, a class of compounds known to possess anti-tumor, anti-inflammatory and antibacterial effects. However, the underlying mechanism of chalcones against colorectal cancer remains unclear. This study reports that HCI-48 mainly targets PIM1 and FGFR1 kinases, thereby eliciting antitumor effects on colorectal cancer growth in vitro and in vivo. HCI-48 inhibited the activity of both PIM1 and FGFR1 kinases in an ATP-dependent manner, as revealed by computational docking models. Cell-based assays showed that HCI-48 inhibited cell proliferation in CRC cells (HCT-15, DLD1, HCT-116 and SW620), and induced cell cycle arrest in the G2/M phase through modulation of cyclin A2. HCI-48 also induced cellular apoptosis, as evidenced by an increase in the expression of apoptosis biomarkers such as cleaved PARP, cleaved caspase 3 and cleaved caspase 7. Moreover, HCI-48 attenuated the activation of downstream components of the PIM1 and FGFR1 signaling pathways. Using patient-derived xenograft (PDX) murine tumor models, we found that treatment with HCI-48 diminished the PDX tumor growth of implanted CRC tissue expressing high protein levels of PIM1 and FGFR1. This study suggests that the inhibitory effect of HCI-48 on colorectal tumor growth is mainly mediated through the dual-targeting of PIM1 and FGFR1 kinases. This work provides a theoretical basis for the future application of HCI-48 in the treatment of clinical CRC.
