Background: To assess the quality of life (QoL) and treatment satisfaction with intermittently-scanned continuous glucose monitoring (isCGM) in women with gestational diabetes mellitus (GDM). Methods: This prospective observational study included 189 women with GDM who completed the Korean version of the Audit of Diabetes-Dependent Quality of Life Questionnaire (K-ADDQoL). Among them, 25 women who utilized isCGM between gestational weeks 30 and 34 completed the Korean version of the Diabetes Treatment Satisfaction Questionnaire change version (K-DTSQc) to evaluate their satisfaction with isCGM during pregnancy. Results: GDM had a negative impact on the perceived QoL in 89.4% of the women. All 19 domains of the K-ADDQoL were adversely influenced by GDM, with the most significant impact on the freedom to eat (weighted impact score, −6.98 ± 2.49, P < 0.001) and the least impact on the sex life (−0.25 ± 0.80, P = 0.008). Younger women and those treated with insulin perceived themselves as being more affected in their QoL due to GDM. Women perceived to have less effect on their QoL attributed to GDM exhibited higher ΔHbA1c one year after delivery (ΔHbA1c, 0.3 ± 0.4% vs. 0.0 ± 0.4% in less affected vs. more affected women). The utilization of isCGM improved treatment satisfaction (overall satisfaction score, 10.36 ± 9.21, P < 0.001), independent of glycemic control during pregnancy. Conclusion Although GDM negatively affects the perceived QoL during pregnancy, attentiveness to GDM management may have a positive impact on long-term glycemic control.Moreover, employing isCGM can enhance treatment satisfaction in women with GDM.

Objective: This study aimed to quantitatively assess abnormalities in the talar dome cartilage using MRI T2 mapping, with additional analyses based on the Lauge-Hansen (LH) classification and anatomical locations. Materials and Methods: This retrospective study analyzed 78 patients who underwent ankle MRI with T2 mapping for acute ankle trauma between January 2021 and October 2022. Patients were classified into the supination (S) and pronation (P) groups based on the LH classification, and then divided into subgroups based on posterior malleolus (PM) involvement. The T2 values for the talar cartilage were quantitatively measured in six anatomical regions defined by the combination of medial vs.lateral and anterior vs. central vs. posterior. The T2 mapping values in each region of the talus were compared between the S and P groups and between the PM and non-PM injury groups using t-tests. The T2 values were also compared between the medial and lateral sides within each group. Results: Among the 78 patients (mean age, 38.62 ± 14.82 years; 47 male), 53 and 25 were in the S and P groups, respectively, and 53 patients showed PM involvement. In comparison with the P group, the S group exhibited higher T2 values in the medial portion (61.27 ± 8.30 vs. 54.03 ± 6.96; P < 0.001) and lower T2 values in the lateral talus (54.95 ± 8.47 vs. 64.15 ± 7.31; P < 0.001). The PM injury group showed higher T2 values in the posterior region than the non-PM injury group (P ≤ 0.011). Within the PM injury group, T2 values were higher in the anteromedial and posterolateral regions than on the opposite sides (P= 0.037 and 0.011, respectively). Conclusion MRI T2 values demonstrated significant regional variations in the talar dome cartilage in acute ankle trauma, and the T2 values may reflect different ankle trauma mechanisms and PM involvement. Thus, T2 mapping can facilitate evaluation of talar cartilage alterations.

The initial molecular cytogenetic characteristics of blasts plays a significant role in determining the treatment course of B-cell acute lymphoblastic leukemia (B-ALL).B-ALL with intrachromosomal amplification of chromosome 21 (iAMP21) has been well known to have unfavorable prognosis. Also, there are previously recognized germline mutations that increase the risk of ALL, such as trisomy 21, Down syndrome. This case report is about a 16-year-old girl who presented with lymphadenitis, purpura, and fever followed by initial lab of elevated white blood cell with blasts.She had some notable facial features, but no typical Down syndrome related one.Bone marrow biopsy and fluorescence in situ hybridization finalized the diagnosis as B-ALL with iAMP21, high-risk group. The minimal residual disease-negative complete remission was achieved after the induction chemotherapy with Korean multicenter high-risk protocol. However, abnormal karyotype was sustained in bone marrow. Microarrays with her buccal swab raised the possibility that the abnormal karyotype was not from the leukemic blasts but rather from the germline. Although she underwent scheduled chemotherapy uneventfully as slow early responder type, thrombocytopenia and abnormal karyotype persisted, leading to the diagnosis of acute myeloid leukemia. Additional chemotherapy and peripheral blood stem cell transplantation was performed which resulted in engraftment. This case highlights the discovery of a constitutional genetic aberration, which played like a silent yet critical background factor for B-ALL with iAMP21. As the number of reported cases are limited, the role of germline chromosome 21 mutation as the indicator for prognosis of B-ALL should be studied further.

Background/Aims: We previously reported that patients with moderate-to-severe ulcerative colitis (UC) often experience common mental disorders (CMDs) such as anxiety and depression, necessitating immediate psychological interventions within the first 4 weeks of diagnosis. In this 3-year follow-up study of the MOSAIK cohort in Korea, we examined the effects of CMDs at initial diagnosis on clinical outcomes and health-related quality of life (HRQoL). Methods: We examined differences in clinical outcomes (evaluated based on clinical response, relapse, hospitalization, and medication use) and HRQoL (assessed using the Inflammatory Bowel Disease Questionnaire [IBDQ] and Short Form 12 [SF-12]) according to Hospital Anxiety and Depression Scale (HADS) scores at diagnosis. Results: In a study involving 199 UC patients, 47.7% exhibited significant psychological distress (anxiety and/or depression) at diagnosis. Clinical follow-up showed no major differences in outcomes, including remission rates, response rates, or hospitalization rates, between patients with anxiety or depression at diagnosis and patients without anxiety or depression at diagnosis. The HRQoL at the end of follow-up was notably lower in those with baseline CMDs, particularly anxiety, across all domains of the IBDQ and SF-12. Linear mixed-effect models revealed that higher HADS scores, as well as higher Mayo scores, were independently associated with lower IBDQ scores and both summary domains of the SF-12. Additionally, regular attendance at follow-up visits during the study period was also related to improvements in HRQoL (all p<0.05). Conclusions While CMDs present at the time of UC diagnosis did not influence long-term clinical outcomes, they persistently impaired HRQoL. Our findings support the routine incorporation of psychological interventions into the long-term management of moderate-to-severe UC.

Purpose: This study compared the outcomes of haploidentical-related donor (HRD) and umbilical cord blood (UCB) hematopoietic stem cell transplantation (HSCT) in pediatric patients with hematologic malignancies. Methods: Data on patients who underwent HRD HSCT with post-transplant cyclophosphamide (n = 41) and UCB HSCT (n = 24) after targeted busulfan-based myeloablative conditioning with intensive pharmacokinetic monitoring between 2009 and 2018 were retrospectively analyzed. Results: The median follow-up durations in the HRD and UCB groups were 7.0 and 10.9 years, respectively. The cumu‑ lative incidence of acute graft-versus-host disease (GVHD) grades II–IV and moderate-to-severe chronic GVHD did not differ significantly between the groups. However, the HRD group demonstrated significantly lower rates of acute GVHD grades III–IV (4.9% vs. 29.2%, p = 0.009) and non-relapse mortality (2.6% vs. 34.2%, p < 0.001) but a higher relapse incidence (32.1% vs. 8.8%, p = 0.004) than the UCB group. The 5-year event-free and overall survival rates were 65.8% and 54.2% (p = 0.204) and 78.0% and 65.7% (p = 0.142) for the HRD and UCB groups, respectively. Multivariate analysis identified disease status as a significant risk factor for overall survival (hazard ratio, 3.24; p = 0.016). Additionally, UCB HSCT exhibited a trend toward worse event-free survival compared to HRD HSCT (hazard ratio, 2.63; p = 0.05). Conclusions These findings indicate that HRD HSCT with post-transplant cyclophosphamide provides promising outcomes compared to UCB HSCT in pediatric patients, with a trend toward improved survival over a long-term follow-up period exceeding a median of 7 years. Thus, HRD HSCT may be a valuable option for pediatric patients with‑ out human leukocyte antigen-matched donors.

Objective: This study investigated potential relationships between the kinetics of nucleolar precursor bodies (NPBs) in the pronucleus and developmental morphokinetics and euploidy in human preimplantation genetic testing for aneuploidy (PGT-A) cycles. Methods: The morphokinetic analysis of 200 blastocysts obtained from 53 PGT-A cycles was performed retrospectively in a time-lapse incubator. At the time of pronuclear breakdown (PNBD), we categorized the blastocysts into two groups based on the kinetic degree of clustering NPBs at the interface of the two pronuclei: clustered NPBs (CL) and non-clustered NPBs (NCL). We then compared morphokinetic parameters, abnormal behavioral events, and the rate of aneuploidy between the two groups. Results: Pronuclear fading and the first cleavage occurred earlier in the NCL group than in the CL group. However, the initiation of blastocyst formation and blastocyst expansion was delayed in the NCL group relative to the CL group. No differences were found in the rate of abnormal cleavage events, such as multinucleation at the 2-cell stage, direct cleavage from one to three cells, and from two to five cells between the CL and NCL groups. However, the fragmentation rate at the 8-cell stage was higher in the NCL group than in the CL group (10.3% vs. 1.9%, p<0.05). Additionally, the euploid rate in the CL group was significantly higher than in the NCL group (37.9% vs. 12.4%, p<0.05). Conclusion These results demonstrate the effectiveness of combining NPB clustering at PNBD with morphokinetics as a parameter for selecting embryos with higher developmental potential in in vitro fertilization.

Purpose: To investigate the clinical efficacy of rebamipide eyedrops in patients with meibomian gland dysfunction (MGD) associated with Sjögren’s syndrome. Methods: The study included 50 patients with Sjögren’s syndrome accompanied by MGD treated with 0.05% (w/v) cyclosporine and 0.15% (w/v) sodium hyaluronate eyedrops. They were divided into two groups: 25 who added rebamipide eyedrops to their existing treatments and a control group of 25 whose treatments did not change. We evaluated the tear breakup time, the Schirmer test and conjunctival staining scores, meibomian gland quality and function, and eyelid margin irregularity before prescribing rebamipide eyedrops and 1 and 3 months after prescription. Additionally, before eyedrops use and 3 months later, meibographic scores were assessed via imaging of the meibomian gland and ocular surface disease index values also were assessed. Results: The rebamipide group exhibited significant improvements in the tear breakup time, conjunctival staining score, and ocular surface disease index compared to before treatment (all p < 0.05). However, the Schirmer test result, meibomian gland quality and function, and eyelid margin irregularity did not differ between either groups before or after treatment. After 3 months of eyedrop use, the rebamipide group exhibited a significantly higher tear breakup time (p < 0.01) and Schirmer test score (p < 0.01) than the control group (p = 0.01), and significantly lower ocular surface disease index and conjunctival staining scores (p < 0.01). Conclusions Addition of rebamipide eyedrops to the conventional treatment of patients with Sjögren’s syndrome accompanied by MGD effectively improves dry eye symptoms and the ocular surface parameters.
