Efficacy and Safety of Panax ginseng Sprout Extract in Subjective Memory Impairment: A Randomized, Double-Blind, Placebo-Controlled Clinical Trial.

Sprout ginseng extract (ThinkGIN™) manufactured through a smart farm system has been shown to improve memory in preclinical studies. This study conducted a 12-week randomized, double-blind, placebo-controlled clinical trial to evaluate the efficacy and safety of ThinkGIN™ for improving memory in subjective memory impairment (SMI). Subjects aged 55 to 75 years with SMI participated in this study. A total of 80 subjects who met the inclusion/exclusion criteria were assigned to the ThinkGIN™ group (n = 40, 450 mg ThinkGIN™/day) or a placebo group (n = 40). Efficacy and safety evaluations were conducted before intervention and at 12 weeks after intervention. As a result of 12 weeks of ThinkGIN™ intake, significant differences in SVLT, RCFT, MoCA-K, PSQI-K, and AChE were observed between the two groups. Safety evaluation (AEs, laboratory tests, vital signs, and electrocardiogram) revealed that ThinkGIN™ was safe with no clinically significant changes. Therefore, ThinkGIN™ has the potential to be used as a functional food to improve memory.

Primary surgery versus pharmacotherapy for newly diagnosed ileocecal Crohn's disease: a hospital-based cohort study.

Background/Aims: Limited knowledge exists regarding the optimal timing and relative advantages of primary surgery compared to medical treatment in ileocecal Crohn's disease (CD). This study aimed to compare long-term outcomes between medication-based treatment versus surgery in newly diagnosed ileocecal CD patients in an Asian population. Methods: Among the 885 patients diagnosed with CD and enrolled in the study site hospital cohort between 1980 and 2013, 93 (10.5%) had ileocecal CD. Patients were categorized into either the surgical or medical remission group based on their initial management strategy that led to remission. The rates of relapse, hospitalization, and surgery after achieving remission were compared using Kaplan-Meier curves. Results: The numbers of patients assigned to surgical and medical remission groups were 15 (17.0%) and 73 (83.0%), respectively. The surgical remission group exhibited a lower relapse rate and longer maintenance of remission (10.7 vs. 3.7 yr; p = 0.017) during a median follow-up of 6.6 years. Hospitalization after the first remission tended to be lower in the surgical remission group (p = 0.054). No cases required repeated intestinal resection after the initial surgical remission, whereas a 23% surgery rate was reported at 5 years after initial medical treatment (p = 0.037). In the multivariable analysis, the initial medication-based treatment was significantly associated with relapse (hazard ratio = 3.23, p = 0.039). Conclusions: In selected cases of localized ileocecal CD, ileocolic resection might be a favorable alternative to medication- based treatment, as it demonstrates a lower relapse rate and longer maintenance of remission.

Optimal Treatment Approaches to Intestinal Behçet's Disease Complicated by Myelodysplastic Syndrome: The KASID and KSBD Multicenter Study.

PURPOSE: Studies on intestinal Behçet's disease (BD) complicated by myelodysplastic syndrome (MDS) are rare, and no established therapeutic guidelines exist. This study aimed to evaluate the clinical presentation and outcomes of patients with intestinal BD complicated by MDS (intestinal BD-MDS) and suggest a treatment strategy. MATERIALS AND METHODS: Data from patients with intestinal BD-MDS from four referral centers in Korea who were diagnosed between December 2000 and December 2022 were retrospectively analyzed. Clinical features and prognosis of intestinal BD-MDS compared with age-, sex-matched intestinal BD without MDS were investigated. RESULTS: Thirty-five patients with intestinal BD-MDS were included, and 24 (70.6%) had trisomy 8. Among the 35 patients, 23 (65.7%) were female, and the median age at diagnosis for intestinal BD was 46.0 years (range, 37.0-56.0 years). Medical treatments only benefited eight of the 32 patients, and half of the patients underwent surgery due to complications. Compared to 70 matched patients with intestinal BD alone, patients with intestinal BD-MDS underwent surgery more frequently (51.4% vs. 24.3%; p=0.010), showed a poorer response to medical and/or surgical treatment (75.0% vs. 11.4%; p<0.001), and had a higher mortality (28.6% vs. 0%; p<0.001). Seven out of 35 patients with intestinal BD-MDS underwent hematopoietic stem cell transplantation (HSCT), and four out of the seven patients had a poor response to medical treatment prior to HSCT, resulting in complete remission of both diseases. CONCLUSION: Patients with intestinal BD-MDS frequently have refractory diseases with high mortalities. HSCT can be an effective treatment modality for medically refractory patients with intestinal BD-MDS.

Effects of COVID-19 vaccines on patient-reported outcomes in patients with inflammatory bowel disease: a multicenter survey study in Korea.

Background/Aims: The impact of vaccination on inflammatory bowel disease (IBD) patients is still unknown, and no studies have assessed the changes in patient-reported outcomes (PROs) after vaccination in patients with IBD. Therefore, in this study, we investigated the impact of vaccines on the PROs of patients with IBD. Methods: We conducted a questionnaire survey of patients with IBD who visited outpatient clinics at 4 specialized IBD clinics of referral university hospitals from April 2022 to June 2022. A total of 309 IBD patients were included in the study. Patient information was collected from a questionnaire and their medical records, including laboratory findings, were reviewed retrospectively. Risk factors associated with an increase in PROs after COVID-19 vaccination were analyzed using logistic regression analyses. In addition, we assessed whether there were differences in variables by vaccine order using the linear mixed model. Results: In multivariate analysis, young age ( < 40 years) and ulcerative colitis (UC) were found to be independent risk factors for aggravation of PROs in patients with IBD. In all patients, platelet count significantly increased with continued vaccination in multiple pairwise comparisons. In UC patients, PROs such as the short health scale, UC-abdominal signs and symptoms, and UC-bowel signs and symptoms were aggravated significantly with continued vaccination. There was no significant increase in the variables of patients with Crohn's disease. Conclusions: Therefore, there may be a need to counsel patients with IBD younger than 40 years of age, and patients with UC before they receive COVID-19 vaccinations.

A Comprehensive Understanding of Post-Translational Modification of Sox2 via Acetylation and O-GlcNAcylation in Colorectal Cancer.

Aberrant expression of the pluripotency-associated transcription factor Sox2 is associated with poor prognosis in colorectal cancer (CRC). We investigated the regulatory roles of major post-translational modifications in Sox2 using two CRC cell lines, SW480 and SW620, derived from the same patient but with low and high Sox2 expression, respectively. Acetylation of K75 in the Sox2 nuclear export signal was relatively increased in SW480 cells and promotes Sox2 nucleocytoplasmic shuttling and proteasomal degradation of Sox2. LC-MS-based proteomics analysis identified HDAC4 and p300 as binding partners involved in the acetylation-mediated control of Sox2 expression in the nucleus. Sox2 K75 acetylation is mediated by the acetyltransferase activity of CBP/p300 and ACSS3. In SW620 cells, HDAC4 deacetylates K75 and is regulated by miR29a. O-GlcNAcylation on S246, in addition to K75 acetylation, also regulates Sox2 stability. These findings provide insights into the regulation of Sox2 through multiple post-translational modifications and pathways in CRC.

The effect of ulinastatin on acute kidney injury in patients undergoing off-pump cardiac bypass surgery.

BACKGROUND: Ulinastatin, an anti-inflammatory and antioxidant trypsin inhibitor, has shown potential in mitigating acute kidney injury (AKI) and reducing serum creatinine levels after various surgeries. This retrospective study aimed to evaluate the effects of ulinastatin on AKI in patients undergoing off-pump coronary artery bypass (OPCAB) surgery. METHODS: We hypothesized that the administration of ulinastatin could prevent AKI in OPCAB. Electrical medical records were reviewed to identify OPCAB patients between January 2015 and June 2020. The utilization of ulinastatin was randomly determined and applied during this period. Acute kidney injury was defined according to the KDIGO guideline, and its incidence was compared between the ulinastatin administration group and the control group. To investigate the effect of ulinastatin on renal function, multivariate logistic regression analysis was used to calculate propensity scores for each group. RESULTS: A total 454 OPCAB were performed, and after following inclusion and exclusion process, 100 patients were identified in the ulinastatin group and 303 patients in the control group. Using 1:2 propensity score matching, we analyzed 100 and 200 patients in the ulinastatin and control groups. The incidence of AKI was similar between the groups (2.5% for the control group, 2.0% for the ulinastatin group, p > 0.999). However, the serum creatinine value on the first post-operative day were significantly lower in the ulinastatin group compared to the control group (0.774 ± 0.179 mg/dL vs 0.823 ± 0.216 mg/dL, P = 0.040), while no significant differences were observed for the other time points (P > 0.05). The length of ICU stay day was significantly shorter in the ulinastatin group (2.91 ± 2.81 day vs 5.22 ± 7.45 day, respectively, P < 0.001). CONCLUSIONS: Ulinastatin did not have a significant effect on the incidence of AKI; it demonstrated the ability to reduce post-operative serum creatine levels at first post-operative day and shorten the length of ICU stay.

Neither hepatic steatosis nor fibrosis is associated with clinical outcomes in patients with intestinal Behçet's disease.

BACKGROUND: Behçet's disease (BD) and nonalcoholic fatty liver disease (NAFLD) are chronic inflammatory diseases that share pathogenetic mechanisms. In this study, we investigated whether NAFLD influences the clinical outcomes in patients with intestinal BD. METHODS: Patients with intestinal BD and available hepatic steatosis index (HSI) and fibrosis-4 (FIB-4) scores were recruited between 2005 and 2022. An HSI of ≥30 and FIB-4 of ≥1.45 were used to diagnose hepatic steatosis and significant liver fibrosis, respectively. The primary outcomes were intestinal BD-related hospitalization, surgery, emergency room visits, or the first use of corticosteroids, immunomodulators, or biologic agents for intestinal BD. RESULTS: A total of 780 patients with BD were selected. The prevalence of hepatic steatosis and significant liver fibrosis were 72.3% and 8.8%, respectively. Multivariate analysis showed that younger age, prior smoking history, concomitant skin lesions, higher white blood cell count, and lower serum albumin levels were independently associated with an increased risk of clinical relapse (all P < 0.05), whereas hepatic steatosis and significant liver fibrosis were not (hazard ratio [HR] = 1.164, 95% confidence interval [CI] 0.923-1.468; P = 0.199 for hepatic steatosis; HR = 0.982, 95% CI 0.672-1.436; P = 0.927 for significant liver fibrosis). CONCLUSION: Hepatic steatosis and liver fibrotic burden were not independently associated with clinical outcomes in patients with intestinal BD.

Effectiveness and Tolerability of Methotrexate Combined with Biologics in Patients with Crohn's Disease: A Multicenter Observational Study.

BACKGROUND: Methotrexate (MTX) combination therapy with biological agents has gained increasing interest. Here, we assessed the efficacy and tolerability of the MTX combination therapy in patients with Crohn's disease (CD). METHODS: We performed a multicenter observational study with 185 patients with CD with MTX and biologics combination therapy; the patients were recruited from three IBD Clinics in Korea. We evaluated the outcomes of the MTX combination therapy and examined the predictive factors of clinical and endoscopic remission. RESULTS: MTX was administered orally to 62.7% of patients; the mean dose was 15.5 mg per week, and the mean treatment duration was 36 months. Of the 169 patients treated with MTX combination therapy for over 6 months, the steroid-free clinical remission rates were 34.3%, 26.0%, 29.8%, and 32.7% at 4, 12, 18, and 24 months, respectively. Previous thiopurine use was a significant negatively associated independent factor (p < 0.001), and a higher dose of MTX (≥ 15 mg/week) was a positively associated independent factor of steroid-free clinical remission (p = 0.035). Ninety-six patients underwent follow-up endoscopy after 28 months, and 36 (37.5%) achieved endoscopic remission. Longer disease duration (p = 0.006), ileocolonic type of Montreal location (p = 0.036), and baseline C-reactive protein (CRP) level of more than 5 mg/L (p = 0.035) were significant negatively associated independent factors and a higher dose of MTX (≥ 15 mg/week) was a positively associated independent factor of endoscopic remission (p = 0.037). CONCLUSIONS: MTX combination therapy with biologics was effective and tolerable in patients with CD.

Association of preoperative blood glucose level with delirium after non-cardiac surgery in diabetic patients.

BACKGROUND: Hyperglycemia has shown a negative association with cognitive dysfunction. We analyzed patients with high preoperative blood glucose level and hemoglobin A1c (HbA1c) level to determine the prevalence of postoperative delirium. METHODS: We reviewed a database of 23,532 patients with diabetes who underwent non-cardiac surgery. Acute hyperglycemia was defined as fasting blood glucose > 140 mg/dl or random glucose > 180 mg/dl within 24 h before surgery. Chronic hyperglycemia was defined as HbA1c level above 6.5% within three months before surgery. The incidence of delirium was compared according to the presence of acute and chronic hyperglycemia. RESULTS: Of the 23,532 diabetic patients, 21,585 had available preoperative blood glucose level within 24 h before surgery, and 18,452 patients reported levels indicating acute hyperglycemia. Of the 8,927 patients with available HbA1c level within three months before surgery, 5,522 had levels indicating chronic hyperglycemia. After adjustment with inverse probability weighting, acute hyperglycemia was related to higher incidence of delirium (hazard ratio: 1.33, 95% CI [1.10,1.62], P = 0.004 for delirium) compared with controls without acute hyperglycemia. On the other hand, chronic hyperglycemia did not correlate with postoperative delirium. CONCLUSIONS: Preoperative acute hyperglycemia was associated with postoperative delirium, whereas chronic hyperglycemia was not significantly associated with postoperative delirium. Irrespective of chronic hyperglycemia, acute glycemic control in surgical patients could be crucial for preventing postoperative delirium.

New genetic biomarkers predicting 5-aminosalicylate-induced adverse events in patients with inflammatory bowel diseases.

Background: Notably, 5-aminosalicylates (5-ASA) are vital in treating inflammatory bowel diseases (IBD). The adverse events of 5-ASA rarely occur but they could be fatal. Objectives: We aimed to discover new genetic biomarkers predicting 5-ASA-induced adverse events in patients with IBD. Design: This was a retrospective observational study. Methods: We performed a genome-wide association study on patients with IBD in South Korea. We defined subset 1 as 39 all adverse events and 272 controls; subset 2 as 20 severe adverse events and 291 controls (mild adverse events and control); subset 3 as 20 severe adverse events and 272 controls; and subset 4 as 19 mild adverse events and 272 controls. Logistic regression analysis was performed and commonly found associated genes were determined as candidate single-nucleotide polymorphisms predicting 5-ASA adverse events. Results: Patients with Crohn's disease (CD) were significantly negatively associated with the development of adverse events compared to patients with ulcerative colitis (UC) (5.3% versus 22.9%). However, sex and age at diagnosis were unassociated with the adverse events of 5-ASA. rs13898676 [odds ratio (OR), 20.33; 95% confidence interval (CI), 5.69-72.67; p = 3.57 × e-6], rs12681590 (OR, 7.35; 95% CI, 2.85-19.00; p = 3.78 × e-5), rs10967320 (OR, 4.51; 95% CI, 2.18-9.31; p = 4.72 × e-5), and rs78726924 (OR, 3.54; 95% CI, 1.69-7.40; p = 7.96 × e-5) were genetic biomarkers predicting 5-ASA-induced severe adverse events in patients with IBD. Conclusion: The adverse events of 5-ASA were more common in patients with UC than those with CD in our study. We found that novel rs13898676 nearby WSB2 was the most significant genetic locus contributing to 5-ASA's adverse event risk.

Hepatic Steatosis but Not Fibrosis Is Independently Associated with Poor Outcomes in Patients with Inflammatory Bowel Disease.

Background/Aims: Increased prevalence of nonalcoholic fatty liver disease (NAFLD) and inflammatory bowel disease (IBD) has been reported. However, the effects of NAFLD on the outcome of IBD remains unclear. We investigated whether the presence of NAFLD could influence the outcomes of patients with IBD. Methods: We recruited 3,356 eligible patients with IBD into our study between November 2005 and November 2020. Hepatic steatosis and fibrosis were diagnosed using hepatic steatosis index of ≥30 and fibrosis-4 of ≥1.45, respectively. The primary outcome was clinical relapse, defined based on the following: IBD-related admission, surgery, or first use of corticosteroids, immunomodulators, or biologic agents for IBD. Results: The prevalence of NAFLD in patients with IBD was 16.7%. Patients with hepatic steatosis and advanced fibrosis were older, had a higher body mass index, and were more likely to have diabetes (all p<0.05). Conclusions: Hepatic steatosis was independently associated with increased risks of clinical relapse in patients with ulcerative colitis and Crohn's disease, whereas fibrotic burden in the liver was not. Future studies should investigate whether assessment and therapeutic intervention for NAFLD will improve the clinical outcomes of patients with IBD.

Risk factors for post-polypectomy bleeding in patients with end-stage renal disease undergoing colonoscopic polypectomy.

BACKGROUND AND AIMS: Little is known about the risk factors of bleeding after colonoscopic polypectomy in patients with end-stage renal disease (ESRD). This study investigated the incidence and risk factors of post-polypectomy bleeding (PPB), including immediate and delayed bleeding, in patients with ESRD. METHODS: Ninety-two patients with ESRD who underwent colonoscopic polypectomy between September 2005 and June 2020 at a single tertiary referral center were included. The patients' medical records were retrospectively reviewed. Patient- and polyp-related factors associated with immediate PPB (IPPB) were analyzed using logistic regression analysis. Additionally, the optimal cutoff polyp size related to a significant increase in the risk of IPPB was determined by performing receiver operating characteristic (ROC) analysis and calculating the area under the ROC curve (AUC). RESULTS: In total, 286 polyps were removed. IPPB occurred in 24 (26.1%) patients and 46 (16.1%) polyps and delayed PPB occurred in 2 (2.2%) patients. According to multivariate analysis, the polyp size (> 7 mm), old age (> 70), and endoscopic mucosal resection (EMR) as the polypectomy method (EMR versus non-EMR) were found to be independent risk factors for IPPB. According to the Youden index method, the optimal cutoff polyp size to identify high-risk polyps for IPPB was 7 mm (AUC = 0.755; sensitivity, 76.1%; specificity, 69.6%). CONCLUSIONS: Colonoscopic polypectomy should be performed with caution in patients with ESRD, especially in those with the following risk factors: advanced age (> 70 years), polyp size > 7 mm, and EMR as the polypectomy method.

Impact of age at diagnosis on long-term prognosis in patients with intestinal Behçet's disease.

BACKGROUND AND AIM: Although age at disease onset is considered to be a significant factor in the prognosis of Crohn's disease, little is known about its influence on the long-term prognosis of those with intestinal Behçet's disease (BD). This study aimed to evaluate the long-term clinical outcomes of patients with intestinal BD according to age of disease onset. METHODS: Patients diagnosed with intestinal BD at < 18, 18-60, and > 60 years of age were classified into early-onset, adult-onset, and late-onset groups, respectively. The influence of disease onset time on clinical prognosis, including specific medical requirements, BD-related intestinal surgery, hospitalization, and emergency room visits, was compared using the log-rank test in a large cohort of patients with intestinal BD. RESULTS: Among 780 patients, 21 (2.7%), 672 (86.2%), and 87 (11.1%) comprised the early-onset, adult-onset, and late-onset groups, respectively. Patients in the early-onset group were more likely to require immunosuppressants than those in the adult-onset group (P = 0.048). Nine (42.9%), 158 (23.5%), and 18 (20.7%) patients in the early-onset, adult-onset, and late-onset groups, respectively, underwent intestinal resection. The early-onset group exhibited a higher risk for intestinal resection than the late-onset (P = 0.043) and adult-onset (P = 0.030) groups. The late-onset group exhibited a higher risk for BD-related hospitalization than the adult-onset group (P = 0.023). CONCLUSIONS: Age at diagnosis affected the clinical course of intestinal BD, including intestinal surgery, hospitalization, and specific medical requirements. Different treatment strategies should be established according to age at diagnosis.

Nanoplastics exacerbate Parkinson's disease symptoms in C. elegans and human cells.

The increasing prevalence of nanoplastics in our environment due to the widespread use of plastics poses potential health risks that are not yet fully understood. This study examines the physiological and neurotoxic effects of these minuscule nanoplastic particles on the nematode Caenorhabditis elegans as well as on human cells. Here, we find that 25 nm polystyrene nanoplastic particles can inhibit animal growth and movement at very low concentrations, with varying effects on their surface groups. Furthermore, these nanoplastic particles not only accumulate in the digestive tract but also penetrate further into extraintestinal tissues. Such nanoplastics significantly compromise the integrity of the intestinal barrier, leading to "leaky gut" conditions and cause mitochondrial fragmentation in muscles, which possibly explains the observed movement impairments. A striking discovery was that these nanoplastics exacerbate symptoms similar to those of Parkinson's disease (PD), including dopaminergic neuronal degeneration, locomotor dysfunction, and accumulation of α-Synuclein aggregates. Importantly, our study demonstrates that the detrimental effects of nanoplastics on the aggregation of α-Synuclein extend to both C. elegans and human cell models of PD. In conclusion, our research highlights the potential health hazards linked to the physicochemical properties of nanoplastics, underlining the urgency of understanding their interactions with biological systems. ENVIRONMENTAL IMPLICATION: The escalating prevalence of nanoplastics in the environment due to widespread plastic usage raises potential health risks. Studies conducted on C. elegans indicate that even low concentrations of 25 nm polystyrene nanoplastics can impair growth and movement. These particles accumulate in the digestive system, compromising the intestinal barrier, causing "leaky gut", as well as inducing Parkinson's-like symptoms. Importantly, in both C. elegans and human cell models of Parkinson's disease, such nanoplastics penetrate tissues or cells and increase α-Synuclein aggregates. This underscores the urgent need to understand the interactions of nanoplastics with biological systems and highlights potential environmental and health consequences.

The Impact of Head Elevation on Prevalence and Severity of Emergence Cough in Male Patients during Endotracheal Extubation.

BACKGROUND Emergence cough during endotracheal extubation can lead to complications. This cough is triggered by the deviation of the endotracheal tube from the airway anatomy, causing pressure on the airway mucosal wall. Head elevation has the potential to align the airway passage with the tube's configuration. In this study, we aimed to investigate the impact of head elevation using a pillow on the prevalence and severity of emergence cough in male patients. MATERIAL AND METHODS A total of 71 male patients undergoing laparoscopic cholecystectomy were randomly assigned to either the head elevation group (n=35) or the control group (n=36). The head elevation group maintained a position with a neck flexion angle of 35º using a pillow, while the control group remained in a neutral position after anesthetic induction. The severity of cough was assessed before, during, and after extubation using a 4-point scale, with grades 2 and 3 indicating cough and grade 3 indicating severe cough. RESULTS The characteristics and intraoperative data of the patients were similar between the two groups. There was no significant difference in the incidence of cough and severe cough between the groups. However, the severity of cough was significantly lower in the head elevation group compared to the control group before extubation (cough scale: 0/5/8/23 vs 1/2/17/15 in the control group vs the head elevation group, P=0.039). The time to extubation, respiratory complications, nausea, pain, and the number of patients receiving fentanyl were comparable between the groups. CONCLUSIONS Head elevation using a pillow effectively reduced the severity of cough before endotracheal extubation during anesthesia emergence in male patients. However, it did not significantly reduce the incidence of cough. These findings highlight the potential benefits of head elevation in minimizing the discomfort associated with emergence cough.

Effectiveness and tolerability of methotrexate monotherapy in Crohn's disease patients: a multicenter observational study.

Background: Methotrexate monotherapy is recommended as a maintenance therapy for Crohn's disease (CD). However, long-term follow-up data are scarce. Objectives: We aimed to examine the effectiveness and tolerability of methotrexate monotherapy in 94 CD patients from three inflammatory bowel disease Clinics in Korea. Design: This was a multicenter retrospective observational study. Methods: Patients with active CD treated with methotrexate monotherapy were included. Clinical characteristics, laboratory indicators, endoscopy indices were evaluated at baseline, 6, 12, and 24 months. Independent factors associated with long-term clinical and endoscopic outcomes were determined. Results: Methotrexate was administered orally (70.2%) or parenterally (29.8%). The mean methotrexate induction dose was 15.3 ± 0.4 mg/week, and the mean duration of therapy was 26.2 months. Of 76 patients who were treated for >6 months, the clinical remission rates were 76.3%, 74.6%, and 80.0% at 6, 12, and 24 months, respectively, by per-protocol analysis. The mean CRP levels were 7.5 ± 1.3, 5.3 ± 1.2, 3.8 ± 0.7, and 2.6 ± 0.5 mg/L at 0, 6, 12, and 24 months, respectively. Of 31 patients who underwent follow-up endoscopy after 27.5 months, the endoscopic remission rate was 38.7%. Baseline hemoglobin level <10 g/dL was a significant independent factor negatively associated with clinical remission at 6 [odds ratio (OR): 0.023, 95% confidence interval (CI): 0.003-0.206, p = 0.001] and 12 (OR: 0.079, 95% CI: 0.009-0.699, p = 0.023) months. Parenteral administration was a significant independent factor positively associated with clinical remission (OR: 11.231, 95% CI: 1.027-122.811, p = 0.047) and endoscopic remission (hazard ratio: 4.711, 95% CI: 1.398-15.874, p = 0.012) at 12 months. Conclusions: Methotrexate monotherapy was effective and tolerable as a maintenance therapy in CD patients.

Characteristics and Treatment Outcomes of Transition among Patients with Inflammatory Bowel Disease.

PURPOSE: This study aimed to assess disease characteristics and outcomes of transition in patient care among adolescent patients with inflammatory bowel disease (IBD). MATERIALS AND METHODS: Data from patients younger than 18 years who were diagnosed with IBD (Crohn's disease, ulcerative colitis, or intestinal Behçet's disease) were investigated. We categorized the patients into two groups: transition IBD group (Group A, diagnosed in pediatric care followed by transfer to/attendance in adult IBD care) and non-transition group (Group B, diagnosed and followed up in pediatric care or adult IBD care without transfer). RESULTS: Data from a total of 242 patients [Group A (n=29, 12.0%), Group B (n=213, 88.0%)] were analyzed. A significantly higher number of patients was diagnosed at an earlier age in Group A than in Group B (p<0.001). Group A patients had more severe disease in terms of number of disease flare ups (p=0.011) and frequency of bowel-related complications (p<0.001). Multiple linear regression analysis showed that Group B patients had more medical non-compliance than Group A patients (ß=2.31, p=0.018). After transition, IBD-related admission frequency, emergency admission frequency, disease flare frequency, and medical non-compliance were significantly improved. CONCLUSION: The transition IBD group had more severe disease. Medical non-compliance was lower in the transition IBD group. Clinical outcomes improved after transition.

Bilateral Cardiac Sympathetic Denervation as a Safe Therapeutic Option for Ventricular Arrhythmias.

Background: The recurrence of ventricular arrhythmias (VAs) in patients who have already undergone treatment with antiarrhythmic medication, catheter ablation, and the insertion of implantable cardioverter defibrillators is not uncommon. Recent studies have shown that bilateral cardiac sympathetic denervation (BCSD) effectively treats VAs. However, only a limited number of studies have confirmed the safety of BCSD as a viable therapeutic option for VAs. Methods: This single-center study included 10 patients, who had a median age of 54 years (interquartile range [IQR], 45-65 years) and a median ejection fraction of 58.5% (IQR, 56.2%-60.8%), with VAs who underwent video-assisted BCSD. BCSD was executed as a single-stage surgery for 8 patients, while the remaining 2 patients initially underwent left cardiac sympathetic denervation followed by right cardiac sympathetic denervation. We evaluated postoperative complications, the duration of hospital stays, and VA-related symptoms before and after surgery. Results: The median hospital stay after surgery was 2 days (IQR, 2-3 days). The median surgical time for BCSD was 113 minutes (IQR, 104-126 minutes). No significant complications occurred during hospitalization or after discharge. During the median follow-up period of 13.5 months (IQR, 10.5-28.0 months) from surgery, no VA-related symptoms were observed in 70% of patients. Conclusion: The benefits of a short postoperative hospitalization and negligible complications make BCSD a safe, alternative therapeutic option for patients suffering from refractory VAs.

The Efficacy of Scalp Nerve Block in Postoperative Pain Management after Microvascular Decompression: A Randomized Clinical Trial.

The scalp nerve block, created by injecting local anesthetics around the scalp nerves, is reported to effectively reduce pain after surgery. In this study, we evaluated the efficacy of scalp nerve block in patients with hemifacial spasm (HFS) undergoing microvascular decompression (MVD). Seventy-four patients who underwent MVD for HFS were enrolled. The block group received scalp nerve block with 0.5% ropivacaine before surgery. The primary outcome was cumulative dose of rescue analgesics 24 h postoperatively. The secondary outcomes were included pain scores, postoperative antiemetic consumption, and Quality of Recovery-15 scale. The cumulative dose of rescue analgesics at 24 h postoperatively was not significantly different between the two groups (4.80 ± 3.64 mg vs. 5.92 ± 3.95 mg, p = 0.633). However, the pain score was significantly reduced in the block group at 6, 12, and 24 h postoperatively. Postoperative antiemetic consumption was lower in the block group than the control group at 12 h. There were no significant differences between the two groups for other secondary outcomes. In MVD for HFS, a preoperative scalp nerve block might reduce postoperative pain in the early postoperative period, but a larger study using a multimodal approach is needed to confirm the efficacy of a scalp block.
