Objectives: Maternal depression negatively affects depression and anxiety symptoms in the offspring. This study examined the association between maternal depression and their adolescent offspring depression and anxiety, as well as the mediating role of emotional trauma in determining the association. Methods: Participants were 237 mothers (46.08±5.00 years) and their adolescent offspring (16.54±1.51 years). The participants completed the Beck Depression Inventory-II, Early Trauma Inventory Self Report-Short Form, Center for Epidemiological Studies Depression Scale for Children, and the Screen for Children’s Anxiety Related Disorders. The mediating effect of emotional trauma on offspring was explored using mediation analysis. Results: Maternal depressive symptoms were significantly correlated with adolescent offspring traumatic experiences, as well as with their depressive and anxiety symptoms. Mediation analysis results showed that emotional trauma of offspring significantly mediated the effect of maternal depression on their depressive and anxiety symptoms. Conclusion Findings indicate that maternal depression was significantly associated with depressive and anxiety symptoms in adolescent offspring, mediated by their emotional trauma. Future research is needed to investigate pathways and intervention strategies to prevent the intergenerational transmission of emotional problems.

Background: The management of distal radius fractures (DRFs) has evolved with the introduction of volar locking plate (VLP) fixation.Nevertheless, despite the low occurrence rates, reduction loss following VLP fixation has been reported in several studies. Our objective was to determine the incidence and features of reduction loss in patients despite the appropriate application of VLP fixation for DRF. Methods: This retrospective study was conducted between March 2017 and August 2023, during which a single hand surgeon performed VLP procedures for DRFs. This study included 379 patients (382 wrists) including 3 patients who underwent bilateral surgery. We identified patients who experienced reduction loss after VLP fixation (group 1) and patients without stability problems (group 2) and compared the 2 groups. Results: The mean age of the patients was 63.5 years, with a standard deviation of 13.8. There were 90 male patients (23.6%) and 289 female patients (75.7%). We identified 14 cases of DRFs, in which reduction loss occurred even after VLP fixation during the follow-up period (group 1, 3.7%). The remaining DRFs were assigned to group 2 (n=368, 96.3%). Among the 14 patients, 7 cases of screw breakage were identified as causing the loss of fracture reduction. As the joint surface collapsed and sank down to the distal row locking screw, 4 cases presented with distal locking screws penetrating into the radiocarpal joint. There were no significant differences between the 2 groups in terms of sex, weight, fracture arm direction, and Arbeitsgemeinschaft für Osteosynthesefragen/Orthopaedic Trauma Association (AO/OTA) fracture classification. However, patients in group 1 were statistically significantly older than those in group 2 (average age, 77.5 years vs. 62 years). Among 4 patients experiencing distal screw violation of the radiocarpal joints, 3 underwent partial or complete screw removal immediately after fracture consolidation or union. Conclusions While rare, reduction loss remains a potential complication following VLP fixation, especially in elderly patients with intra-articular DRFs. However, with diligent monitoring and timely intervention, such as implant removal if necessary, acceptable outcomes can still be attained.

Background: In this study, we aimed to investigate postoperative radiographic parameters for predicting flexor tendon rupture after volar plate fixation for distal radius fractures. Methods: In this retrospective cohort study, postoperative radiographs of 15 cases of flexor tendon rupture were included as a flexor tendon rupture group. Additionally, data from 45 patients with non-flexor tendon rupture (control group), matched in terms of age, sex, and fracture type (1 : 3) to the flexor tendon rupture group, were reviewed in terms of fracture reduction and plate position. We assessed the Soong grade, plate-to-critical line distance (PCLD), and plate-to-volar rim distance to determine plate position and used other parameters to analyze anatomical reduction including radial tilt, ulnar variance, coronal carpal translation, radius-radial styloid distance, volar tilt, sagittal carpal alignment (SCA), and radius-volar lip distance (RVLD). Results: We identified 3 significant predictive factors for flexor tendon rupture after volar plate fixation for distal radius fractures.The mean PCLD and SCA were significantly greater in the flexor tendon rupture group than in the control group (p < 0.001). The mean RVLD was smaller in the flexor tendon rupture group than in the control group (p = 0.033). Logistic regression analysis was performed to examine the importance of the variables. Conclusions Our findings underscore the importance of PCLD, SCA, and RVLD as significant risk factors for flexor tendon rupture.Accurate plate positioning, achieving appropriate anatomical reduction, and vigilant monitoring for signs of plate irritation in highrisk patients may help prevent flexor tendon rupture.

Background: and Purpose: Empathy comprises cognitive and emotional components.However, the impairments in empathy among individuals with mild cognitive impairment (MCI) and dementia of the Alzheimer’s type (DAT) are not well understood, particularly in the context of depression, which may exacerbate these deficits. This study aimed to evaluate the effects of neurodegeneration and depression on empathetic abilities. Methods: The study included 31 healthy elderly (HE) individuals, 30 patients with amnestic multi-domain MCI (amMCI), and 30 patients with DAT. Empathy was assessed using the Korean-Multifaceted Empathy Test (K-MET), and the Interpersonal Response Index (IRI).Participants were classified as depressed or non-depressed using the Geriatric Depression Scale. A two-way MANOVA was conducted to examine differences in empathy based on group and depressive status. Results: A significant interaction between group and depressive status was found for both cognitive and emotional empathy on the K-MET, but not on the IRI. In the depressed group, cognitive empathy scores were lower in the order of HE, amMCI, and DAT. Similarly, in the non-depressed group, the HE group performed better than both amMCI and DAT, with no significant difference between the latter two. Regarding emotional empathy, the depressed HE group scored higher than both amMCI and DAT, with no significant difference between these groups. In the non-depressed group, emotional empathy declined in the order of HE, amMCI, and DAT. Conclusions These findings indicate that both neurodegeneration and depression significantly impair empathetic abilities, with declines in cognitive and emotional empathy evident at the MCI stage, regardless of depressive status.

Background: s/Aims: In recent years, many minimally invasive techniques have been introduced to reduce the number of ports in laparoscopic cholecystectomy (LC), offering benefits such as reduced postoperative pain and improved cosmetic outcomes. ArtiSential®is a new multi-degree-of-freedom articulating laparoscopic instrument that incorporates the ergonomic features of robotic surgery, potentially overcoming the spatial limitations of laparoscopic surgery. ArtiSential® LC can be performed using only two ports. This study aims to compare the surgical outcomes of ArtiSential® LC with those of single-fulcrum LC. Methods: This retrospective study compared ArtiSential® LC and single-fulcrum LC among LCs performed for gallbladder (GB) stones at the same center, analyzing the basic characteristics of patients; intraoperative outcomes, such as operative time, estimated blood loss, and intraoperative GB rupture; and postoperative outcomes, such as length of hospital stay, incidence of postoperative complications, and postoperative pain. Results: A total of 88 and 63 patients underwent ArtiSential® LC and single-fulcrum LC for GB stones, respectively. Analysis showed that ArtiSential® LC resulted in significantly fewer cases of surgeries longer than 60 minutes (30 vs. 35 min, p = 0.009) and intraoperative GB ruptures (2 vs. 10, p = 0.007). In terms of postoperative outcomes, ArtiSential® LC showed better results in the respective visual analog scale (VAS) scores immediately after surgery (2.59 vs. 3.73, p < 0.001), and before discharge (1.44 vs. 2.02, p = 0.01). Conclusions ArtiSential® LC showed better results in terms of surgical outcomes, especially postoperative pain. Thus, ArtiSential®LC is considered the better option for patients, compared to single-fulcrum LC.

Background: s/Aims: Balancing surgical risks and benefits is crucial for managing non-functional pancreatic neuroendocrine tumors (NF-PNETs). Despite high postoperative pancreatic fistula (POPF) rates, studies on postoperative complications of sporadic NFPNETs are scarce. Thus, this study aimed to investigate postoperative complications and identify risk factors for POPF. Methods: A retrospective review of 166 NF-PNET surgeries performed at Severance Hospital between February 2000 and August 2023 was conducted. Results: Age > 65 years and higher American Society of Anesthesiology (ASA) grade were not significantly correlated with severe complications (odds ratio [OR]: 1.10, p = 0.871 and OR: 1.47, p = 0.491, respectively). Surgical procedures included enucleation (13.9%), distal pancreatectomy (50.0%), central pancreatectomy (4.8%), pancreaticoduodenectomy (PD) (26.5%), and total pancreatectomy (4.8%). Severe complications occurred in 12.05% of surgeries. The overall incidence of all POPFs including biochemical leaks was 53%, while clinically relevant POPF (grade B or C) occurred in 7.8% of patients. Logistic regression showed that PD (OR: 3.94, p = 0.092) tended to be risk factor for POPF and that diameter of the main pancreatic duct (MPD) ≤ 3 mm was a significant risk factor for POPF (OR: 0.22, p = 0.008). A pancreas thickness (PT)/MPD ratio > 4.47 on preoperative computed tomography predicted all POPFs in PD patients (OR: 11.70, p = 0.001). Conclusions Age and comorbidities had no significant impact on surgical outcomes. PD was associated with higher serious complications and POPF rates. The PT/MPD ratio is a valuable preoperative tool for predicting POPF risk in PD patients.

Selecting the optimal surgical treatment for multilevel cervical spondylotic myelopathy and radiculopathy significantly affects symptom improvement, postoperative prognosis, and quality of life. Proper patient selection and precise surgical execution are crucial for achieving successful outcomes, considering the favorable natural course of cervical radiculopathy. Several factors must be considered, including the number of affected segments, spinal alignment, kyphosis degree, stiffness, and surgeon expertise, when determining the surgical approach for cervical spondylotic myelopathy. An anterior approach is commonly used in cases that involve fewer than three segments with mild kyphosis, whereas posterior laminoplasty or anterior cervical discectomy and fusion (ACDF) are effective for cases with more than three segments with maintained lordosis. Both the degree of stiffness and spinal cord compression need to be considered for cases with kyphotic deformity. ACDF may be suitable when anterior structures are the primary source of compression and mild kyphosis is present. The decision between laminoplasty or laminectomy and fusion depends on the kyphosis degree for multilevel compression with kyphosis. An evaluation of cervical rigidity is required for severe kyphosis, and posterior laminectomy and fusion may be effective for flexible kyphosis, whereas a staged posterior–anterior–posterior approach may be required for rigid kyphosis to address both deformity and neural compression. This review summarizes recent research and presents illustrative cases of optimal surgical decision-making for various cervical spondylotic radiculopathy and myelopathy presentations.

Connecting peptide (C-peptide), a byproduct of insulin biosynthesis, has diverse cellular and biological functions. Particulate mat-ter 2.5 (PM2.5 ) adversely affects human skin, leading to skin thickening, wrinkle formation, skin aging, and inflammation. This study aimed to investigate the protective effects of C-peptide against PM2.5 -induced damage to skin cells, focusing on oxidative stressas a key mechanism. C-peptide mitigated NADPH oxidation and intracellular reactive oxygen species (ROS) production inducedby PM2.5 . It also suppressed PM2.5 -induced NADPH oxidase (NOX) activity and alleviated PM2.5 -induced NOX1 and NOX4 expression. C-peptide protected against PM2.5 -induced DNA damage, lipid peroxidation, and protein carbonylation. Additionally, C-peptide mitigated PM2.5 -induced apoptosis by inhibiting intracellular ROS production. In summary, our findings suggest that C-peptide mitigates PM2.5 -induced apoptosis in human HaCaT keratinocytes by inhibiting intracellular ROS production and NOX activity.
