Purpose:
This study investigated the impact of nusinersen on health-related quality of life (HRQoL), functional performance, and caregiver burden in patients with infantile-onset spinal muscular atrophy (SMA), addressing a growing interest in disease-modifying treatments.
Methods:
A 14-month observational study was conducted to evaluate changes in HRQoL and functional performance using the Pediatric Quality of Life Inventory (PedsQL) Infant Scales and the Pediatric Evaluation of Disability Inventory Computer Adaptive Test (PEDI-CAT). Caregiver burden was assessed through the Assessment of Caregiver Experience with Neuromuscular Disease (ACEND). Motor function was evaluated using the Children’s Hospital of Philadelphia Infant Test of Neuromuscular Disorders (CHOP INTEND). Correlations between CHOP INTEND scores, functional performance, and caregiver burden were analyzed.
Results:
Eight patients with infantile-onset SMA and their caregivers participated, with a median treatment initiation age of 4.6 months (range, 1.1 to 15.1). CHOP INTEND scores showed significant improvement (P<0.001), whereas all PedsQL Infant Scale scores declined. Conversely, the PEDI-CAT revealed significant enhancements in daily activities, mobility, and social-cognitive domains (all P<0.001). Caregiver burden lessened across most dimensions (P<0.001), with the exception of the time-related burden (P=0.731). Higher CHOP INTEND scores correlated with improvements in PEDI-CAT domains and a reduction in caregiver burden related to sitting/play and transfer activities.
Conclusion
The study demonstrates the positive effects of nusinersen on functional performance and caregiver burden in patients with infantile-onset SMA. However, discrepancies were observed in HRQoL outcomes, suggesting a need for further research that includes SMA-specific outcome measures to comprehensively assess the treatment's impact on patients' lives.

4.Clinical outcomes and optimal indications for nonoperative management of acute appendicitis in adult patients: a comprehensive literature review
Annals of Coloproctology 2025;41(2):107-118
Appendectomy as the standard treatment for acute appendicitis has been challenged by accumulating evidence supporting nonoperative management with antibiotics as a potential primary treatment. This review aimed to summarize the clinical outcomes and the optimal indications for nonoperative management of acute appendicitis in adults. Current evidence suggests that uncomplicated and complicated appendicitis have different pathophysiologies and should be treated differently. Nonoperative management for uncomplicated appendicitis was not inferior to appendectomy in terms of complications and length of stay, with less than a 30% failure rate at 1 year. The risk of perforation and postoperative complications did not increase even if nonoperative management failed. Complicated appendicitis with localized abscess or phlegmon could also be treated conservatively, with a success rate of more than 80%. An interval appendectomy following successful nonoperative management is recommended only for patients over the age of 40 years to exclude appendiceal malignancy. The presence of appendicoliths increased the risk of treatment failure and complications; thus, it may be an indication for appendectomy. Nonoperative management is a safe and feasible option for both uncomplicated and complicated appendicitis. Patients should be informed that nonoperative management may be a safe alternative to surgery, with the possibility of treatment failure.

Background:
In vitro and animal studies have demonstrated that bone morphogenetic protein-7 (BMP-7), renowned for its osteogenic properties, also exerts beneficial effects on muscle metabolism by enhancing myogenesis and reversing muscle atrophy. Despite being proposed as a common regulatory factor for both muscle and bone, the impact of BMP-7 on human muscle health has not been thoroughly investigated.
Methods:
This cross-sectional study involved 182 community-dwelling older adults who underwent a comprehensive geriatric assessment in South Korea. Sarcopenia was diagnosed using Asian-specific cutoffs, and serum BMP-7 levels were quantified via enzyme immunoassay.
Results:
The mean age of the participants was 72.2±7.3 years, with 62.6% being female. After adjustments for confounders, serum BMP-7 levels were not significantly different between individuals with and without sarcopenia, nor were there differences based on skeletal muscle mass, strength, or physical performance levels (p=0.423 to 0.681). Likewise, no correlations were detected between circulating BMP-7 levels and any sarcopenia assessment metrics such as skeletal muscle index, grip strength, gait speed, or chair stand completion times (p=0.127 to 0.577). No significant associations were observed between increases in serum BMP-7 concentrations and the risk of sarcopenia or poor muscle phenotypes (p=0.431 to 0.712). Stratifying participants into quartiles based on serum BMP-7 levels also indicated no differences in sarcopenia-related parameters (p=0.663 to 0.996).
Conclusion
Despite experimental evidence supporting BMP-7’s role in muscle metabolism, this study found no significant association between serum BMP-7 levels and clinical indicators of muscle health in older adults. These findings challenge the utility of serum BMP-7 as a biomarker for sarcopenia in this demographic.

Purpose:
Mitochondria-accumulating amphiphilic peptide (Mito-FF) was designed to selectively target mitochondria in cancer cells and enhance anticancer effects through its unique structure. Mito-FF consists of (1) diphenylalanine, a β-sheet-forming building block critical for self-assembly; (2) triphenylphosphonium, a mitochondrial targeting moiety guiding the peptide to mitochondria; and (3) pyrene, a fluorescent probe enabling visualization of its accumulation and selfassembly. This study evaluates the anticancer efficacy of Mito-FF in breast cancer cells and explores its combination with paclitaxel, a standard therapy for breast cancer, focusing on its modulation of the epithelial-mesenchymal transition (EMT) pathway.
Methods:
In vitro and in vivo experiments were performed using MCF-7 and MDA-MB-231 breast cancer cell lines and their respective xenograft models. Cell viability, migration, EMT marker expression, and apoptosis-related proteins were analyzed.
Results:
Mito-FF demonstrated superior inhibition of cell viability and migration compared to paclitaxel alone in both cell lines. Combination therapy with Mito-FF and paclitaxel resulted in enhanced reduction of cell viability and migration. EMT markers were significantly modulated, with decreased mesenchymal markers (Snail and vimentin) and increased epithelial marker (E-cadherin) following combination treatment. Furthermore, the combination therapy synergistically elevated proapoptotic markers such as poly (adenosine diphosphate-ribose) polymerase and reduced anti-apoptotic markers such as myeloid cell leukemia 1. In vivo experiments revealed a marked reduction in tumor volume with combination therapy, accompanied by the highest expression levels of E-cadherin and pro-apoptotic marker Bim.
Conclusion
Mito-FF, designed for mitochondrial targeting and visualization, exhibited potent anticancer effects when combined with paclitaxel, in the breast cancer cells.

Purpose:
Determining the extent of radical lymphadenectomy at clinical early stage is challenging. We aimed to investigate the appropriate extent of lymphadenectomy in clinical early-stage right colon cancer.
Methods:
Patients with clinical stage 0 or I right colon cancer who underwent curative surgery from January 2007 to December 2021 were included in this retrospective study. The extent of lymph node (LN) metastases based on the distribution of LN metastases (LND: LND1 pericolic nodes, LND2 intermediate nodes, LND3 apical nodes), along with the depth of submucosal (SM) invasion (classed into SM1–3), were analyzed.
Results:
Of the 348 patients, distribution across pathologic stages was as follows: 30 patients (8.6%) at stage 0, 207 (59.5%) at stage I, 52 (14.9%) at stage II, and 59 (17.0%) at stage III. In pT1 tumor patients, LN metastases varied by SM invasion depth: 3.6% in SM1 (all LND1), 5.1% in SM2 (all LND1), and 17.5% in SM3 (LND1 10%, LND2 5%, LND3 2.5%). For pT2, pT3, and pT4 stages, LN metastasis rates were 16.2% (LND1 11.3%, LND2 3.8%, LND3 1.3%), 39.7% (LND1 28.9%, LND2 8.4%, LND3 2.4%), and 50% (LND1 25%, LND2 25%), respectively. Tumor invasion depth and lymphovascular invasion were identified as significant risk factors for LN metastasis extending to LND2–3.
Conclusion
Complete mesocolic excision should be considered for right-sided colon cancer because tumor infiltration deeper than SM2 could metastasize to LND2 or further. If preoperative endoscopy confirms SM1 or SM2 invasion, D2 lymphadenectomy could be a limited surgical option.

Purpose:
We aimed to evaluate health-related quality of life (HRQoL) in intestinal failure (IF) patients after different modes of intestinal rehabilitation.
Methods:
HRQoL was assessed using the generic 36-item Short Form Survey (SF-36, ver. 2) and visual analogue scale (VAS) in 6 different areas: diet, sleep, gastrointestinal (GI) symptoms, diarrhea, musculoskeletal pain, and other symptoms.
Results:
Twenty-two patients completed the questionnaires, of which 7 had received intestinal transplant (ITx), 9 were continuing home total parenteral nutrition (HPN), and 6 had tapered off total parenteral nutrition (TPN). SF-36 physical component summary scores were highest in the ITx group (median, 65.6; interquartile range [IQR], 31.6–80.3) compared to the HPN (median, 48.4; IQR, 44.7–66.3) or tapered group (median, 54.2; IQR, 45.2–61.6). Mental component summary scores were lowest in the ITx group (median, 48.8; IQR, 37.1–63.6), compared to the TPN (median, 60.2; IQR, 41.6–78.5) or tapered group (median, 51.0; IQR, 48.8–56.0). Differences were not significant in all items of the SF-36. VAS scores showed that patients in the ITx group showed the best results in diet (0.9), gastrointestinal (GI) symptoms (1.4), and musculoskeletal pain (2.4). There was a significant difference in sleep (P = 0.036), with the ITx (1.43) and HPN groups (1.33) showing better outcomes compared with the tapered group (4.67). Patients in the tapered group showed the least favorable results in all performance areas, except GI symptoms.
Conclusion
SF-36 did not show a significant difference between the ITx, HPN, and tapered groups, but VAS showed a significant difference in sleep between groups. Further studies, including serial data, will allow a better understanding of the effects of different modes of intestinal rehabilitation.

Purpose:
Regenerative medicine is expected to offer an alternative to liver transplantation for treating liver diseases in the future, with one significant challenge being the establishment of an effective stem cell administration route. This study assessed the antifibrogenic effects of adipose-derived stem cells (ASCs) in a liver fibrosis mouse model, focusing on 2 methods of delivery: intravenous injection and scaffold implantation.
Methods:
An extracellular matrix mimic scaffold was utilized for culturing peroxisome proliferator-activated receptor gamma coactivator 1-alpha–overexpressing ASCs (tASCs). These scaffolds, laden with tASCs, were then implanted subcutaneously in mice exhibiting liver fibrosis. In contrast, the Cell groups received biweekly intravenous injections of tASCs for 4 weeks. After 4 weeks, tissue samples were harvested from the euthanized mice for subsequent analysis.
Results:
Real-time PCR and Western blot analyses on liver tissues, focusing on markers like alpha-smooth muscle actin (α-SMA), matrix metalloproteinase-2, and transforming growth factor-beta 1 (TGF-β1), showed that both delivery routes substantially lowered fibrotic and inflammatory markers compared to controls (P < 0.05), with no significant differences between the routes. Histological examinations, along with immunohistochemical analysis of α-SMA, collagen type I alpha, and TGF-β1, revealed that the scaffold implantation approach resulted in a greater reduction in fibrosis and lower immunoreactivity for fibrotic markers than intravenous delivery (P < 0.05).
Conclusion
These findings indicate that delivering tASCs via a scaffold could be more effective, or at least similarly effective, in treating liver fibrosis compared to intravenous delivery. Scaffold implantation could offer a beneficial alternative to frequent intravenous treatments, suggesting its potential utility in clinical applications for liver disease treatment.

Purpose:
The purpose of this study was to develop an approach to alleviate the discomfort caused by sandbag compression after a bone marrow examination. This research examined the effects of applying a pressure hemostasis band on bleeding, pain, and discomfort at the bone marrow examination site.
Methods:
This study was conducted with a nonequivalent control group non-synchronized design. For 74 patients under evaluation who underwent bone marrow examination, sandbag compression was applied to the examination site in the control group (n=37), and a pressure hemostasis band was applied to the intervention group (n=37). In both groups, absolute bed rest was performed for two hours, and bleeding, pain, and discomfort at the examination site were measured.
Results:
After two hours of the bone marrow examination, there was no difference in bleeding on the gauze between the two groups (F=0.59, p=.444). Bleeding occurred in three patients in the intervention group and six in the control group (χ 2 =1.14, p=.479), with no cases of hematoma detected in either group. One hour post-examination, the control group experienced significantly higher pain (F=5.45, p=.022) and discomfort (F=5.68, p=.020) than the intervention group. However, pain and discomfort levels were similar between groups after two hours.
Conclusion
Compared to the sandbag compression group, the band application group showed no difference in bleeding and experienced less pain and discomfort at the examination site. This confirms that the pressure hemostasis band is a suitable alternative to sandbag compression in post-examination care.
