Choosing the right adjuvant therapy for stage III-IVA endometrial cancer: A comparative analysis of chemoradiotherapy and chemotherapy.

OBJECTIVE: The optimal adjuvant treatment for patients with locally advanced endometrial cancer (EC) remains debatable. We comparatively analyzed recurrence patterns and survival outcomes in patients with stage III-IVA EC treated with adjuvant chemotherapy (CT) exclusively or combined with radiotherapy (CRT). METHODS: We retrospectively analyzed 184 patients treated for stage III-IVA EC at 2 tertiary institutions between 2010 and 2021. All patients underwent standard primary surgery and received either CT alone (n = 89) or CRT (n = 95) as an adjuvant treatment. We compared the failure patterns, recurrence-free survival (RFS), and overall survival (OS) between the CT and CRT groups. RESULTS: The median follow-up period was 54.8 months. Most patients underwent pelvic (94.6%) or para-aortic (75.5%) lymphadenectomies. The 5-year RFS was 69.2% with CRT versus 56.3% with CT (P = 0.038), and 5-year OS was 86.1% versus 78.9% (P = 0.357). Pelvic and para-aortic recurrence rates were significantly higher in the CT group (pelvic: 29.2%; para-aortic: 20.2%) than in the CRT group (pelvic: 10.5%; para-aortic: 6.3%). The CRT group showed a higher rate of distant recurrence (CRT, 23.2% vs. CT, 14.6%) however, the 5-year cumulative incidence of distant recurrence was not significantly different between the two groups (CRT, 28% vs. CT, 35%). CONCLUSIONS: This study highlights the potential benefits of adjuvant CRT in patients with stage III-IVA EC. The incorporation of molecular classification is necessary to derive optimal personalized adjuvant treatment strategies for this patient population.

Cervical enamel projections from a periodontal perspective: A scoping review.

Cervical enamel projections (CEPs) represent a unique developmental and anatomical anomaly wherein the enamel structure extends apically beyond the cemento-enamel junction of the tooth. In this scoping review, the existing literature on CEPs was evaluated to delineate their characteristics, prevalence, predilection for specific teeth and surfaces, clinical significance, and management approaches. Searches were conducted on MEDLINE (PubMed), Cochrane Library, and Embase databases using the keywords "enamel projection(s)" or "ectopic enamel." In total, 24 studies meeting inclusion criteria were included in the review. The prevalence of CEPs varied widely (8.3%-85.1%), predominantly manifesting as grade I or grade III. Mandibular first and second molars exhibited a higher incidence of CEPs, with a notable predilection for buccal surfaces. The consensus in most studies was that CEPs are associated with localized periodontal diseases. Recommendations inclined toward the removal of ectopic enamel during periodontal surgery to enhance periodontal attachment formation. However, decision-making should involve careful consideration of the benefits and drawbacks based on individual circumstances.

Alleviative Effect of Geniposide on Lipopolysaccharide-Stimulated Macrophages via Calcium Pathway.

In this study, we investigated how geniposide (a bioactive ingredient of gardenia fruit) acts on lipopolysaccharide (LPS)-stimulated macrophages. Griess reagent assay, Fluo-4 calcium assay, dihydrorhodamine 123 assay, multiplex cytokine assay, quantitative RT-PCR, and flow cytometry assay were used for this study. Data showed that geniposide at concentrations of 10, 25, and 50 µM reduced significantly the levels of nitric oxide, intracellular Ca2+, and hydrogen peroxide in LPS-activated RAW 264.7. Multiplex cytokine assay showed that geniposide at concentrations of 10, 25, and 50 µM meaningfully suppressed levels of IL-6, G-CSF, MCP-1, and MIP-1α in RAW 264.7 provoked by LPS; additionally, geniposide at concentrations of 25 and 50 µM meaningfully suppressed the levels of TNF-α, IP-10, GM-CSF, and MIP-1ß. Flow cytometry assay showed that geniposide reduces significantly the level of activated P38 MAPK in RAW 264.7 provoked by LPS. Geniposide meaningfully suppressed LPS-induced transcription of inflammatory target genes, such as Chop, Jak2, Fas, c-Jun, c-Fos, Stat3, Nos2, Ptgs2, Gadd34, Asc, Xbp1, Nlrp3, and Par-2. Taken together, geniposide exerts alleviative effects in LPS-stimulated macrophages via the calcium pathway.

Efficient CRISPR-Cas12f1-Mediated Multiplex Bacterial Genome Editing via Low-Temperature Recovery.

CRISPR-Cas system is being used as a powerful genome editing tool with developments focused on enhancing its efficiency and accuracy. Recently, the miniature CRISPR-Cas12f1 system, which is small enough to be easily loaded onto various vectors for cellular delivery, has gained attention. In this study, we explored the influence of temperature conditions on multiplex genome editing using CRISPR-Cas12f1 in an Escherichia coli model. It was revealed that when two distinct targets in the genome are edited simultaneously, the editing efficiency can be enhanced by allowing cells to recover at a reduced temperature during the editing process. Additionally, employing 3'-end truncated sgRNAs facilitated the simultaneous single-nucleotide level editing of three targets. Our results underscore the potential of optimizing recovery temperature and sgRNA design protocols in developing more effective and precise strategies for multiplex genome editing across various organisms.

Multimodal neural correlates of dispositional resilience among healthy individuals.

Resilient individuals are less likely to develop psychiatric disorders despite extreme psychological distress. This study investigated the multimodal structural neural correlates of dispositional resilience among healthy individuals. Participants included 92 healthy individuals. The Korean version of the Connor-Davidson Resilience Scale and other psychological measures were used. Gray matter volumes (GMVs), cortical thickness, local gyrification index (LGI), and white matter (WM) microstructures were analyzed using voxel-based morphometry, FreeSurfer, and tract-based spatial statistics, respectively. Higher resilient individuals showed significantly higher GMVs in the inferior frontal gyrus (IFG), increased LGI in the insula, and lower fractional anisotropy values in the superior longitudinal fasciculus II (SLF II). These resilience's neural correlates were associated with good quality of life in physical functioning or general health and low levels of depression. Therefore, the GMVs in the IFG, LGI in the insula, and WM microstructures in the SLF II can be associated with resilience that contributes to emotional regulation, empathy, and social cognition.

Level of Anxiety Shows a Positive Correlation With the Frequency of Acute Cystitis Recurrence in Women.

PURPOSE: Previous studies have simply confirmed recurrence of acute cystitis negatively affects a patient's psychological state. This study was performed to assess the impact of the recurrence of urinary tract infections on anxiety and depression and further assess whether there is a correlation between the number of recurrences and the degree of anxiety and depression. METHODS: This cross-sectional study enrolled patients with recurrent cystitis who visited a tertiary care center between April 2018 and June 2022. For eligible patients, depression and anxiety were assessed by the Patient Health Questionnaire-9 and State-Trait Anxiety Inventory. Among the clinical characteristics, factors that independently affected the degree of depression and anxiety were analyzed. Additionally, the relationship between the level of anxiety, depression, and the number of recurrent cystitis was assessed. RESULTS: A total of 112 female patients with recurrent cystitis were enrolled in this study. The proportion of patients with depression (moderate, 8%; severe, 0%) was relatively low compared with that of patients with anxiety (moderate, 22.3%; severe, 68.8%). Multivariate regression analysis showed that more recurrent episodes were significantly associated with higher anxiety scores (P<0.001). It was confirmed that longer disease duration is associated with higher depression scores (P=0.031). Additionally, there was a positive correlation between the number of recurrences and State-Trait Anxiety Inventory and Patient Health Questionnaire-9 scores (r=0.362, P<0.001 and r=0.248, P=0.009, respectively). CONCLUSION: Our study reveals that recurrent cystitis notably increases patients' anxiety, correlating with the frequency of recurrences. Disease duration is also linked to depression. These findings emphasize the importance of preventing urinary tract infection recurrences to reduce psychological complications. To reinforce these results, larger cohort studies are necessary.

Predicting treatment outcomes in patients with panic disorder: Cross-sectional and two-year longitudinal structural connectome analysis using machine learning methods.

PURPOSE: This study examined the relationship between structural brain networks and long-term treatment outcomes in patients with panic disorder (PD) using machine learning methods. METHOD: The study involved 80 participants (53 PD patients and 27 healthy controls) and included clinical assessments and MRI scans at baseline and after two years (160 MRIs). Patients were categorized based on their response to two-year pharmacotherapy. Brain networks were analyzed using white matter tractography and network-based statistics. RESULTS: Results showed structural network changes in PD patients, particularly in the extended fear network, including frontal regions, thalamus, and cingulate gyrus. Longitudinal analysis revealed that increased connections to the amygdala, hippocampus, and insula were associated with better treatment response. Conversely, overconnectivity in the amygdala and insula at baseline was associated with poor response, and similar patterns were found in the insula and parieto-occipital cortex related to non-remission. This study found that SVM and CPM could effectively predict treatment outcomes based on network pattern changes in PD. CONCLUSIONS: These findings suggest that monitoring structural connectome changes in limbic and paralimbic regions is critical for understanding PD and tailoring treatment. The study highlights the potential of using personalized biomarkers to develop individualized treatment strategies for PD.

Assessment of Bone Marrow Involvement in Extranodal NK/T-Cell Lymphoma: Positron Emission Tomography versus Bone Marrow Biopsy, and the Significance of Minimal Involvement by EBV+ Cells (KROG 18-09).

PURPOSE: This study aims to investigate the diagnostic significance of positron emission tomography/computed tomography (PET/CT) in assessing bone marrow (BM) involvement through a comparison of PET/CT findings with BM biopsy in extranodal natural killer/T-cell lymphoma. MATERIALS AND METHODS: The medical records of 193 patients were retrospectively reviewed. Patients were categorized as having early-stage (PET-ES) or advanced-stage (PET-AS) disease based on PET/CT results. The BM involvement was classified into three groups according to BM biopsy: gross BM involvement, minimal BM involvement (defined as the presence of a limited number of Epstein-Barr virus-positive cells in BM), and no involvement. Calculations of the accuracy of PET/CT in detecting BM involvement and analysis of the clinical outcomes (progression-free survival [PFS] and overall survival [OS]) according to the BM biopsy status were performed. RESULTS: PET/CT exhibited a sensitivity of 64.7% and a specificity of 96.0% in detecting gross BM involvement. For detecting any (both gross and minimal) BM involvement, the sensitivity was 30.4%, while the specificity was 99.0%. Only one patient (0.7%) demonstrated gross BM involvement among the PET-ES group. Survival outcomes of the PET-ES group with minimal BM involvement (3-year PFS, 55.6%; OS, 77.0%) were closer to those of the PET-ES group with no BM involvement (3-year PFS, 62.2%; OS, 80.6%) than to those of the PET-AS group (3-year PFS, 20.1%; OS, 29.9%). CONCLUSION: PET/CT exhibits high specificity, but moderate and low sensitivity in detecting gross and minimal BM involvement, respectively. The clinical significance of minimal BM involvement for patients in the PET-ES group may be limited.

Cardiac Evaluation before and after Oral Propranolol Treatment for Infantile Hemangiomas.

Background: Most recent clinical practice guidelines addressing the management of infantile hemangiomas (IHs) recommend oral propranolol, a non-selective beta-adrenergic antagonist, as first-line treatment. However, few reports have provided continuous follow-up data regarding cardiac evaluations. Methods: Sixty-four patients diagnosed with IHs and treated with oral propranolol before 2 years of age at the Department of Pediatrics, Kangbuk Samsung Hospital (Seoul, Republic of Korea), with regular examinations between 2017 and 2021, were included. Cardiac evaluations, including electrocardiography, Holter monitoring, chest X-ray, and echocardiography, were performed. Results: Sixty-four patients with IHs successfully underwent continuous follow-up cardiac evaluations. The median age at diagnosis was 2 weeks (1 day to 34.3 weeks). The median age at treatment initiation was 13.6 weeks (2.4-87.9 weeks), the mean longitudinal diameter of hemangioma at diagnosis was 2.8 ± 2.1 cm (0.3-12.0 cm), and the mean percentage of size decrease after 1 year of oral propranolol treatment was 71.8%. None of the 64 patients experienced severe adverse side effects during propranolol treatment. There was no statistically significant differences in echocardiographic function and electrocardiographic data after treatment. Conclusions: Propranolol treatment ≥6 months was effective and safe without significant cardiac toxicity in the treatment of patients with infantile hemangiomas.

Lactobacillus plantarum LPYC225 mixture partially modulates the vaginal bacterial community of Gardnerella vaginalis-infected bacterial vaginosis in mice.

Bacterial vaginosis (BV) is defined as dysbiosis of the vaginal microbiome associated with the depletion of Lactobacilli and excessive growth of commensal or pathogenic bacteria. This study investigated the effects of lactic acid bacteria (LAB) mixture (LM; InoRexyne™) on the vaginal bacterial community of Gardnerella vaginalis (G. vaginalis)-infected BV mice. Single LAB and LM exhibited antibacterial and anti-inflammatory effects by inhibiting G. vaginalis growth and pro-inflammatory markers in RAW 264.7 cells. Administering LM did not significantly alter the vaginal architecture or fecal short-chain fatty acids but did significantly inhibit the vaginal interleukin-6 levels in the high LM group compared to the GV group. LM administration decreased the relative abundances of Enterobacter, Escherichia coli, and Bacteroides vulgatus in vaginal flushing fluids compared to the GV group. LM partially alleviated BV by inhibiting G. vaginalis growth and modulating the vaginal bacterial community, providing new insights into its modulatory effects on the vaginal microbiome in BV.

Early Trauma Subtypes are Differentially Related to Anxiety Symptomatology and Suicidal Ideation in Panic Disorder.

OBJECTIVE: Early trauma significantly affects the severity of panic disorder (PD) symptoms and suicidal ideation. However, few studies have explored the specific effects of different early trauma subtypes on PD. This study analyzed how childhood trauma subtypes, including general, physical, emotional, and sexual, influence panic and phobia levels and suicidal ideation in adults with PD and healthy controls (HCs). METHODS: In total, 455 adults with PD and 149 HCs participated in this study. The independent variables were sociodemographic and clinical variables such as coping strategies and early trauma subtypes from the Early Trauma Inventory Self Report-Short Form. The dependent variables were the Albany Panic and Phobia Questionnaire (APPQ), the Panic Disorder Severity Scale, and the Scale for Suicide Ideation (SSI). RESULTS: Early emotional trauma significantly influenced the APPQ scores, whereas early physical trauma significantly influenced the SSI scores in patients with PD. However, in HCs, only early emotional trauma was significantly associated with the APPQ and SSI scores. CONCLUSION: These findings highlight the influence of early trauma subtypes on the phobic symptom severity of PD and suicidal ideation among patients with PD. Early emotional trauma is associated with the severity of phobic symptoms, whereas early physical trauma is associated with suicidal ideation, suggesting distinct clinical outcomes based on the type of trauma in patients with PD.
