Change of Symptoms after Total Hip Arthroplasty in Patients with Hip-Spine Syndrome.

Purpose: Elderly patients with degenerative diseases undergo treatment for the hip and spine; these patients present with various symptoms. This study focused on patients with residual symptoms, predominantly pain, even after receiving treatment for their spinal lesions. Materials and Methods: Patients who underwent total hip arthroplasty (THA) between 2016 and 2022 at a single tertiary hospital were included in the study. Of the 417 patients who underwent primary THA, a retrospective review of 40 patients with previous lesions of the spine was conducted. Patients were stratified to two cohorts: Patients with symptoms related to the spine (Group A), and those with hip-related symptoms (Group B). Pre- and postoperative comparisons of groups A and B were performed. Results: Improvements in patients' symptoms were observed in groups A and B after THA. In Group A, the mean preoperative visual analog scale (VAS) score was 5.10±0.876, which showed a postoperative decrease to 2.70±1.767. In Group B, the mean preoperative VAS score was 5.10±1.539, which showed a postoperative decrease to 2.67±1.493. Conclusion: According to the findings, promising results were achieved with THA in treatment of debilitating diseases of the hip for both the prognosis of the disease, as well as the patients' symptoms. In addition, in some cases elderly patients with dual pathologies underwent treatment for spinal lesions without performance of any evaluation related to the hip. Thus, evaluation of a patient's hip must be performed and performance of THA in patients with symptoms even after treatment of spinal lesions is recommended.

Perfectionism, test anxiety, and neuroticism determines high academic performance: a cross-sectional study.

BACKGROUND: Academic performance is an important issue for Korean students. Various psychological factors contribute to academic performance. We aimed to evaluate the psychological factors that affect academic performance integratively. METHODS: A total of 102 academic high achievers and 120 comparison participants were recruited. We evaluated psychological factors (test anxiety, perfectionism, personality traits, resilience, and self-efficacy) and measured academic performance using the College Scholastic Ability Test and the current college grade. We compared psychological factors and academic performance between the academic high achiever and comparison groups. Multiple linear regression was then conducted to identify the significant psychological factors for high academic performance. Further, we used cluster analysis to classify the comparison group by the significant psychological factors and compared them among clusters and academic high achievers to determine the psychological characteristics of academic high achievers. RESULTS: The academic high achiever group showed lower test anxiety (p = .002), less neuroticism (p = .001), higher self-efficacy (p = .028), and less socially prescribed perfectionism (p < .001) than the comparison group. Multiple linear regression results (p = .020) clarified that neuroticism (p = .020), test anxiety level (p = .047), and perfectionism (p = .035) were important factors predicting better academic performance. Academic high achievers had moderate test anxiety and perfectionism levels, with the best performance on the College Scholastic Ability Test. CONCLUSIONS: Neuroticism, test anxiety levels, and perfectionism are important psychological factors for high academic performance. Interventions targeting these factors may help to improve academic accomplishments.

Is ulnar shortening osteotomy effective for the treatment of ulnar styloid impaction syndrome compared to ulnar impaction syndrome?

PURPOSE: This study aimed at evaluating the outcomes of ulnar shortening osteotomy (USO) for the treatment of ulnar styloid impaction syndrome (USIS) and to compare them with those of USO for the treatment of ulnar impaction syndrome (UIS). METHODS: We enrolled 144 patients who underwent USO between March 2015 and October 2021. The patients were divided into a UIS group (group I, n = 93) and a USIS group (group II, n = 51). Clinical and radiological parameters, including Disabilities of the Arm, Shoulder, and Hand (DASH) score, ulnar variance, ulnar styloid length, and ulnar styloid process index (USPI), were collected pre-operatively and one year post-operatively, and a comparative analysis was performed. RESULTS: The DASH score showed significant improvement in both groups (p < .001 and p < .001), and there was no significant difference between the two groups one year after surgery (p = .143). The USPI was significantly different between the two groups (p < .001). The ulno-lunate and ulno-triquetrum distances showed significant increases in both groups, with significant differences between the two groups (p = .020, and p < .001, respectively). The incidence of post-operative arthritic changes in the distal radioulnar joint was significantly greater in the UIS group than that in the USIS group (21 vs 3, respectively; p = .017). No remarkable differences were observed in the post-operative evidence of chondromalacia at the last follow-up between the two groups. CONCLUSION: The USO, which was performed as a treatment for USIS showed reliable outcomes compared to the USO for the treatment of UIS. Therefore, USO is a viable option for the treatment of USIS.

Diallyl trisulfide suppresses dextran sodium sulfate-induced mouse colitis: NF-κB and STAT3 as potential targets.

Diallyl trisulfide (DATS), one of the volatile constituents of garlic oil, has been reported to possess antioxidant, anti-inflammatory, and anti-carcinogenic properties. In this study, DATS (10µmol) given orally for 7days before and for another 7days after starting administration of 2.5% dextran sulfate sodium (DSS) in drinking water protected against colitis induced by DSS in male ICR mice. DATS significantly inhibited the DSS-induced DNA binding of NF-κB, phosphorylation of IκBα and the expression of pro-inflammatory proteins, such as cyclooxygenase-2 and inducible nitric oxide synthase, which are major target proteins of NF-κB. The DSS-induced DNA binding and phosphorylation at the Tyr 705 residue of signal transducer and activator of transcription 3 (STAT3), and expression of its major target protein cyclin D1 in mouse colonic mucosa were also attenuated by DATS administration. Likewise, DSS-induced phosphorylation of extracellular signal-regulated kinase 1/2 was suppressed by DATS treatment. In conclusion, DATS ameliorates the DSS-induced mouse colitis presumably by blocking inflammatory signaling mediated by NF-κB and STAT3.

Curcumin Inhibits STAT3 Signaling in the Colon of Dextran Sulfate Sodium-treated Mice.

Turmeric (Curcuma longa L., Zingiberaceae) has a long history of use in medicine for the treatment of inflammatory conditions. One of the major constituents of turmeric is curcumin (diferuloylmethane), which is responsible for its characteristic yellow color. In the present study, we have examined the chemoprotective effects of curcuminon dextran sulfate sodium (DSS)-induced mouse colitis. For this purpose, we pre-treated male ICR mice with curcumin (0.1 or 0.25 mmol/kg in 0.05% carboxymethyl cellulose) by gavage for a week and then co-treated the animals with curcumin by gavage and 3% DSS in drinking water for another 7 days. Our study revealed that administration of curcumin significantly attenuated the severity of DSS-induced colitis and STAT3 signaling in mouse colon. The levels of the cell cycle regulators CDK4 and cylinD1 were significantly reduced by curcumin administration. Moreover, the expression of p53, which is an upstream regulator of the CDK4-cylinD1 complex, was inhibited by curcumin treatment.
