RESUMEN
Purpose@#Tumescent in nipple-sparing mastectomy (NSM) has been reported to increase the risk of necrosis by impairing blood flow to the skin flap and nipple-areolar complex. At our institution, we introduced a tumescent-free robotic NSM using the da Vinci single-port system (Intuitive Surgical, Inc.). @*Methods@#We conducted a retrospective analysis of patients who underwent tumescent-free robotic NSM between October 2020 and March 2023 at Asan Medical Center (Seoul, Korea). Clinicopathological characteristics, adverse events, and operative time were evaluated. @*Results@#During the study period, 118 patients underwent tumescent-free robotic NSM. Thirty-one patients (26.3%) experienced an adverse event. Five patients (4.2%) were classified as grade III based on the Clavien-Dindo classification and required surgery. The mean total operative time was 467 minutes for autologous tissue reconstruction (n = 49) and 252 minutes for implants (n = 69). No correlation was found between the cumulative number of surgical cases and the breast operative time (P = 0.30, 0.52, 0.59 for surgeons A, B, C) for the 3 surgeons. However, a significant linear relationship (P < 0.001) was observed, with the operative time increasing by 13 minutes for every 100-g increase in specimen weight. @*Conclusion@#Tumescent-free robotic NSM is a safe procedure with a feasible operative time and few adverse events.
RESUMEN
Purpose@#This study aimed to investigate the frequency of BRCA testing and related factors among young breast cancer patients (age < 40 years) in South Korea. @*Materials and Methods@#We conducted a nationwide retrospective cohort study using data from the Health Insurance Review and Assessment claims. Newly diagnosed breast cancer patients younger than 40 were included. Annual BRCA testing ratios (number of BRCA test recipients/the number of patients undergoing breast cancer surgery in each year) were analyzed by region and health care delivery system. We investigated the location of breast cancer diagnosis and BRCA testing. @*Results@#From January 2010 to December 2020, there were 25,665 newly diagnosed young breast cancer patients, of whom 12,186 (47.5%) underwent BRCA testing. The BRCA testing ratios increased gradually from 0.084 (154/1,842) in 2010 to 0.961 (1,975/2,055) in 2020. Medical aid (vs. health insurance) and undergoing surgery in metropolitan cities or others (vs. Seoul), general hospitals, and clinics (vs. tertiary hospitals) were associated with a lower likelihood of BRCA testing. While 97.8% of the patients diagnosed in Seoul underwent BRCA testing in Seoul, 22.9% and 29.2% of patients who were diagnosed in metropolitan areas and other regions moved to Seoul and underwent BRCA testing, respectively. @*Conclusion@#The frequency of BRCA testing has increased over time in South Korea, with Seoul showing a particularly high rate of testing. About one-quarter of patients diagnosed with breast cancer outside of Seoul moved to Seoul and underwent BRCA testing.
RESUMEN
Objective@#Although maintenance treatment for mood disorders is important, the treatment discontinuation rate is reported to be high. This study aimed to investigate the dropout rates and associated factors in mood disorders. @*Methods@#The patients in a mood disorder clinic (n = 535) were examined. Demographic and clinical factors, scores of psychometric scales, time to dropout from initial treatment in patients with bipolar disorder (BP) (n = 288) and depressive disorder (DD) (n = 143) were evaluated based on database of the mood disorder clinic. @*Results@#Among the studied patients with BP and DD, 50% showed dropout in 4.05 and 2.17 years, respectively. The mean survival times were 8.90 years in bipolar disorder I (BP-I), 5.19 years in bipolar II disorder, 3.22 years in bipolar disorder not otherwise specified, 4.24 years in major depressive disorder, and 4.03 years in other depressive disorders.In the multivariate Cox proportional hazards regression model in the BP group, diagnosis BP-I was found to be significantly related to the decrease in dropout rate (hazard ratio [HR] = 0.22, p = 0.001); however, increased past suicide attempt number was significantly related to the increase in dropout rate (HR = 1.13, p = 0.017). In the DD group, none of anxiety disorders as comorbidity, increased scores of openness, and extraversion personality were related to the increase in dropout rate. @*Conclusion@#Patients with BP, especially BP-I, showed a lower dropout rate as compared to patients with other mood disorders.
RESUMEN
Purpose@#This study aimed to evaluate age-stratified radiographic features in temporomandibular joint osteoarthritis using cone-beam computed tomography. @*Materials and Methods@#In total, 210 joints from 183 patients (144 females, 39 males, ranging from 12 to 88 years old with a mean age of 44.75±19.97 years) diagnosed with temporomandibular joint osteoarthritis were stratified by age. Mandibular condyle position and bony changes (flattening, erosion, osteophytes, subchondral sclerosis, and subchondral pseudocysts in both the condyle and articular eminence, thickening of the glenoid fossa, joint space narrowing, and joint loose bodies) were evaluated through cone-beam computed tomography. After adjusting for sex, the association between age groups and radiographic findings was analyzed using both a multiple regression model and a multinomial logistic regression model (α=0.05). @*Results@#The prevalence of joint space narrowing and protruded condyle position in the glenoid fossa significantly increased with age (P<0.05). The risks of bony changes, including osteophytes and subchondral pseudocysts in the condyle; flattening, erosion, osteophyte, and subchondral sclerosis in the articular eminence; joint loose bodies; and thickening of the glenoid fossa, also significantly rose with increasing age (P<0.05). The number of radiographic findings increased with age; in particular, the increase was more pronounced in the temporal bone than in the mandibular condyle (P<0.05). @*Conclusion@#Increasing age was associated with a higher frequency and greater diversity of bony changes in the temporal bone, as well as a protruded condyle position in the glenoid fossa, resulting in noticeable joint space narrowing in temporomandibular joint osteoarthritis.
RESUMEN
Purpose@#The Avoid Axillary Sentinel Lymph Node Biopsy After Neoadjuvant Chemotherapy (ASLAN) trial aims to demonstrate the oncologic safety of omitting axillary surgery in patients with excellent response after neoadjuvant chemotherapy (NACT) for early human epidermal growth factor 2 (HER2)-positive (+)/triple-negative breast cancer (TNBC) who have undergone breast-conserving surgery (BCS) and adjuvant radiotherapy. The ASLAN trial will provide crucial information that could change the procedure in highly selected patients undergoing axillary surgery after NACT. @*Methods@#ASLAN is a prospective, multicenter, and single-arm surgical trial. The recruitment will be conducted among five tertiary care hospitals in the Republic of Korea. The total number of patients to be recruited will be 178, and we plan to complete patient enrollment by December 2023. The enrollment is considered among patients with HER2+ breast cancer (BC) or TNBC at clinical stage T1–3N0–1M0 who are expected to achieve breast pathological complete response (BpCR) based on a combination of radiologic imaging and physical examination after NACT. BCS was performed on eligible patients. After BCS, patients who showed BpCR were enrolled with the omission of sentinel lymph node biopsy (SLNB). The primary study endpoint upon completion of this trial is 5-year recurrence-free survival, and the secondary endpoints include the 5-year ipsilateral breast tumor recurrence interval, 5-year ipsilateral axillary recurrence interval, 5-year distant metastasis-free survival, 5-year BC-specific survival, 5-year overall survival, 5-year contralateral BC-free survival, re-operation rate according to breast biopsy after NACT, adverse events within 5 years, and quality of life.Discussion: Several clinical trials are currently underway to determine whether SLNB can be omitted after NACT in patients with HER2+ BC or TNBC that are expected to achieve pathologic complete response. The ASLAN trial is expected to provide valuable clues regarding the feasibility of omitting axillary surgery in highly selected patients.
RESUMEN
Background@#The rapid economic development of South Korea provides a unique model to study changes in the clinical characteristics, treatment approaches, and clinical outcomes of patients with rheumatic mitral stenosis (MS) relative to socioeconomic growth. @*Methods@#From the Multicenter mitrAl STEnosis with Rheumatic etiology (MASTER) registry, 2,337 patients diagnosed with moderate or severe rheumatic MS between January 2001 and December 2020 were analyzed. Patients were grouped into consecutive 5-year intervals based on their year of diagnosis. Clinical characteristics, echocardiographic data, and clinical outcomes were assessed. @*Results@#Over 20 years, the severity of mitral stenosis increased from 79.1% to 90.2%; similarly, the average age at diagnosis increased from 54.3 to 63.0 years (all P < 0.001). Comorbidities such as hypertension and atrial fibrillation increased (6.3% to 29.5% and 41.4% to 46.9%, respectively; all P for trend < 0.05). The rate of mitral intervention within five years after diagnosis increased from 31.2% to 47.4% (P for trend < 0.001). However, clinical outcomes of rheumatic mitral stenosis deteriorated over time in the composite outcomes (log-rank test, P < 0.001). Conversely, the incidence of stroke remained stable (60.6–73.7%; P < 0.001), which might be attributed to the increased use of anticoagulation therapy. @*Conclusion@#This study observed an increase in patient age, comorbidities, and valve disease severity as the country transitioned from a developing to developed status. Despite a rise in mitral valve interventions, clinical outcomes deteriorated over 20 years, highlighting the need for modified treatment approaches to improve patient outcomes.
RESUMEN
Objectives@#The purpose of this study was to examine the patterns of use of oral aripiprazole treatment in children and adolescents diagnosed with autism spectrum disorder (ASD) at a university medical center in Korea. @*Methods@#We retrospectively reviewed the medical records of 164 outpatient children and adolescents diagnosed with ASD by child and adolescent psychiatrists. Patient demographic characteristics, clinical features, age and dose of aripiprazole treatment, associated adverse events, and concomitant medications, etc. were evaluated. @*Results@#Aripiprazole treatment was initiated at a mean age of 7.64 years, at a mean initial dose of 1.15 mg. Methylphenidate was often co-administered with aripiprazole. The most commonly reported adverse effects were increased appetite and weight gain, which in some cases led to discontinuation of medication. @*Conclusion@#A follow-up study is warranted to evaluate the efficacy and safety of aripiprazole treatment in Korean children and adolescents diagnosed with ASD, and it is crucial to consider their clinical characteristics and response to treatment in the evaluation.
RESUMEN
Autism spectrum disorder (ASD) is diagnosed by the clinical decision of a trained professional based on the Diagnostic and Statistical Manual for Mental Disorders, Fifth Edition or International Classification of Diseases 11th Revision diagnostic criteria. To obtain information for diagnostic formulation, professionals should explore detailed developmental history, and can use structured or semi-structured assessment tools to observe interaction between the child and parents or strangers. Diagnostic assessment should include a profile of the strength and weaknesses of the individual and should be conducted using an optimal approach by a multidisciplinary team with appropriate techniques and experience. Assessment of language, cognitive, neuropsychological, and adaptive functioning should be conducted in ASD individuals prior to establishing an individualized treatment plan. Genetic testing, brain magnetic resonance imaging or electroencephalogram testing can be considered for identification of underlying causes.
RESUMEN
Background@#Cyclosporine (CS) has been effectively used in various skin diseases, but gastrointestinal (GI) adverse events are so common. However, there is no standardized treatment for managing CS-induced GI adverse events. @*Objective@#To analyze the effectiveness of two empirical GI medications, an H2 receptor antagonist (H2RA) and proton pump inhibitor (PPI), in relieving CS-induced GI adverse events. @*Methods@#This is a prospective, randomized clinical trial conducted at Ajou University Hospital. The patients completed a gastrointestinal symptom rating scale (GSRS) questionnaire to assess GI symptoms before and after taking the drugs. @*Results@#A total of 60 patients, divided into a PPI group (n=30) and an H2RA group (n=30), were analyzed. The onset of GI events occurred in 6.04 days on average. GSRS scores improved significantly in both groups (p＜0.01). While abdominal pain, reflux syndrome, and indigestion syndrome consistently improved, changes in diarrhea syndrome and constipation syndrome were not statistically significant. The overall change in GSRS scores was higher in the PPI group, but the difference was not significant (p=0.76). @*Conclusion@#Both PPI and H2RA significantly improved CS-induced GI side effects, with PPI showing a slight advantage over H2RA, but the cost of PPIs should be considered when deciding on first-line therapy. GI side effects typically appeared within 6.04 days of starting CS therapy, highlighting the importance of close monitoring and personalized intervention for improving patient compliance.
RESUMEN
Systemic sclerosis (SSc), also called scleroderma, is a rare debilitating autoimmune disease of the connective tissue characterized by microvascular damage, specific immunologic abnormalities, and progressive fibrosis of the skin and internal organs. The disease may be associated with serious visceral complications involving the pulmonary, gastrointestinal, cardiac and renal systems, why early identification is important. Cutaneous telangiectasia was originally one of the diagnostic criteria of the CREST syndrome (calcinosis, Raynaud’s phenomenon, esophageal dysmotility, sclerodactyly, and telangiectasias), and is now included in the 2013 American College of Rheumatology/European League Against Rheumatism criteria for the diagnosis of SSc. We report herein three cases of SSc who presented our department for telangiectasia, because eruptive telangiectasia on exposed area associated with high titer of antinuclear antibody could be the first sign of SSc.
RESUMEN
Objective@#To investigate whether reader training improves the performance and agreement of radiologists in interpreting unenhanced breast magnetic resonance imaging (MRI) scans using diffusion-weighted imaging (DWI). @*Materials and Methods@#A study of 96 breasts (35 cancers, 24 benign, and 37 negative) in 48 asymptomatic women was performed between June 2019 and October 2020. High-resolution DWI with b-values of 0, 800, and 1200 sec/mm 2 was performed using a 3.0-T system. Sixteen breast radiologists independently reviewed the DWI, apparent diffusion coefficient maps, and T1-weighted MRI scans and recorded the Breast Imaging Reporting and Data System (BI-RADS) category for each breast. After a 2-h training session and a 5-month washout period, they re-evaluated the BI-RADS categories. A BI-RADS category of 4 (lesions with at least two suspicious criteria) or 5 (more than two suspicious criteria) was considered positive.The per-breast diagnostic performance of each reader was compared between the first and second reviews. Inter-reader agreement was evaluated using a multi-rater κ analysis and intraclass correlation coefficient (ICC). @*Results@#Before training, the mean sensitivity, specificity, and accuracy of the 16 readers were 70.7% (95% confidence interval [CI]: 59.4–79.9), 90.8% (95% CI: 85.6–94.2), and 83.5% (95% CI: 78.6–87.4), respectively. After training, significant improvements in specificity (95.2%; 95% CI: 90.8–97.5; P = 0.001) and accuracy (85.9%; 95% CI: 80.9–89.8; P = 0.01) were observed, but no difference in sensitivity (69.8%; 95% CI: 58.1–79.4; P = 0.58) was observed. Regarding inter-reader agreement, the κ values were 0.57 (95% CI: 0.52–0.63) before training and 0.68 (95% CI: 0.62–0.74) after training, with a difference of 0.11 (95% CI: 0.02–0.18; P = 0.01). The ICC was 0.73 (95% CI: 0.69–0.74) before training and 0.79 (95% CI: 0.76–0.80) after training (P = 0.002). @*Conclusion@#Brief reader training improved the performance and agreement of interpretations by breast radiologists using unenhanced MRI with DWI.
RESUMEN
Objective@#Sibling relationships in early childhood can have a positive impact on children’s social interaction and communication skills. Similarly, autistic children can benefit from interactions with their siblings, who can serve as readily available partners for social interaction. However, there is a lack of research on the effects of siblings based on specific characteristics of the sibling. Therefore, the aim of this study is to compare social interactions and communication skills of autistic children based on sibling status and characteristics. @*Methods@#We conducted a retrospective data review involving 895 autistic children and their siblings at Seoul National University Bundang Hospital. Variety of diagnostic assessments or questionnaires were administered. Based on the characteristics of the data, Quade’s test for nonparametric analysis of covariance was used to compare autism-related symptoms and levels of functioning of the autistic child according to 1) sibling status, 2) birth order, 3) sex, and 4) diagnosis of the sibling. Pearson correlation was used to explore associations between the sibling age gap and different clinical scores. @*Results@#Having siblings was associated with fewer difficulties in restricted and repetitive behaviors. Based on the comparison of the Autism Diagnostic Interview-Revised scores, autistic children with multiple siblings demonstrated better nonverbal behaviors. Autistic children with autistic siblings experienced greater difficulties in social interactions and communications, such as peer relationships, sharing enjoyment, and engaging in social imitative play. @*Conclusion@#The study revealed differences in social interactions and communication skills of autistic children based on sibling status, birth order, affected sibling, age gap, and sex.
RESUMEN
Patients with chronic myeloid leukemia (CML) now have an improved life expectancy similar to that of the general population due to the introduction of tyrosine kinase inhibitors (TKIs). However, many patients experience mild to severe adverse events while undergoing TKI treatment. This review aimed to discuss the adverse events of TKIs, including myocardial infarction and hypertension, and comprehensively analyze strategies for minimizing vascular complications.Current Concepts: Near-fatal cardiovascular events (CVEs) are common among patients receiving nilotinib and ponatinib. However, those receiving other TKIs, such as imatinib and dasatinib, rarely experience CVEs. Among these CVEs, vascular complications, including peripheral arterial occlusion, venous occlusion, and hypertension, are exacerbated in patients with pre-existing vascular risk factors and prolonged TKI use. Therefore, it is crucial to assess predisposing factors to vascular complications and select the optimal TKI to minimize serious CVEs before initiating therapy. Additionally, patients should be closely monitored for vascular complications during nilotinib and ponatinib treatment.Discussion and Conclusion: Despite advancements in therapeutic approaches and research on CML leading to the development of target-specific TKIs aiming to minimize side effects, newer generations are not entirely devoid of adverse events. Hence, it is important for patients and physicians to be knowledgeable about these medications to effectively monitor for side effects, particularly those that are life-threatening, such as vascular toxicity. It is now more important than ever to carefully observe symptoms and perform adequate testing to identify at-risk individuals early and avoid preventable adverse events.
RESUMEN
Objective@#Face-to-face evaluation is the most important in psychiatric evaluation, but smart healthcare, including non-face-to-face evaluation, can be beneficial considering the situation in which face-to-face evaluation is limited or the preventive aspect of mental illness. In this paper, we aimed to check whether mental health screening tests have the same significance as paper-based tests even when collected through mobile applications. @*Methods@#A smart mental healthcare screening test was conducted on the 1,327 community subjects. We measured two indicators of depression (Patient Health Questionnaire 9-item scale, PHQ-9) and anxiety (Generalized Anxiety Disorder 7-item scale, GAD-7) to check mental health conditions. @*Results@#The average Cronbach’s alpha value of the PHQ-9 questionnaire was good at 0.870. As a result of PHQ-9’s principal component analysis, one component with an eigenvalue of 1 or more was identified, which is suitable to be described as a single factor. The average Cronbach’s alpha value of the GAD-7 was 0.919. The structural validity of the GAD-7 was confirmed through principal component analysis. @*Conclusion@#Our results show that PHQ-9 and GAD-7 scales performed through mobile applications can have the same meaning as paper-based tests. Surveys using a tablet PC, or smartphone application can monitor residents’ mental health and accumulate data. Based on these data, smart mental health management can check the mental health of residents and treat mental illness in connection with medical services.
RESUMEN
Purpose@#This study aimed to analyze the waiting time for initial treatment after breast cancer diagnosis and determine the factors influencing treatment delay in South Korea. @*Methods@#This nationwide retrospective cohort study was conducted using the Health Insurance Review and Assessment data. The participants were classified according to the regions where their biopsy and treatment were performed (Seoul-Seoul, Metro-Metro, OtherOther, Metro-Seoul, Other-Seoul). Waiting time was analyzed according to regional subgroup, year of diagnosis, and type of treatment. Multivariable logistic regression models were constructed to identify the factors associated with treatment delay (after 30 days of diagnosis). @*Results@#A total of 133,514 participants newly diagnosed between January 2010 and December 2017 were included in the study. The median waiting time for initial treatment in the total population increased from 8 days, in 2010, to 14 days, in 2017. In the Seoul-Seoul group, the waiting time increased from 10 days, in 2010, to 16 days, in 2017. Although the median waiting time was approximately 10 days in the Metro-Metro and Other-Other groups, it was 27 and 24 days, in the Metro-Seoul and Other-Seoul group, respectively, in 2017. The proportion of delayed upfront surgery by more than 30 days was higher in the Metro-Seoul (odds ratio [OR], 8.088; 95% confidence interval [CI], 7.357–8.893; p < 0.001) and OtherSeoul (OR, 6.210; 95% CI, 5.717–6.750; p < 0.001) groups than in the Metro-Metro (OR, 1.468; 95% CI, 1.352–1.594; p < 0.001) and Other-Other (reference) groups. Previous medical history and treatment at tertiary hospital were observed as factors related to delayed surgery. @*Conclusion@#Waiting times for breast cancer surgery have increased across all regions of Korea, with those traveling to Seoul experiencing particularly long wait times.
RESUMEN
Fertility preservation is a major concern in young patients diagnosed with breast cancer and planning to receive multimodality treatment, including gonadotoxic chemotherapy with or without age-related decline through long-term endocrine therapy. Most breast cancer patients undergo multimodality treatments; many short-term and long-term side effects arise during these therapies. One of the most detrimental side effects is reduced fertility due to gonadotoxic treatments with resultant psychosocial stress. Cryopreservation of oocytes, embryos, and ovarian tissue are currently available fertility preservation methods for these patients. As an adjunct to these methods, in vitro maturation or gonadotropinreleasing hormone agonist could also be considered. It is also essential to communicate well with patients in the decision-making process on fertility preservation. It is essential to refer patients diagnosed with breast cancer on time to fertility specialists for individualized treatment, which may lead to desirable outcomes. To do so, a multimodal team-based approach and in-depth discussion on the treatment of breast cancer and fertility preservation is crucial. This review aims to summarize infertility risk related to currently available breast cancer treatment, options for fertility preservation and its details, barriers to oncofertility counseling, and psychosocial issues.
RESUMEN
This article provides an annual update of Korean breast cancer statistics, including the incidence, tumor stage, type of surgical treatment, and mortality. The data was collected from the Korean Breast Cancer Society registry system and Korean Central Cancer Registry.In 2019, 29,729 women were newly diagnosed with breast cancer. Breast cancer has continued to increase in incidence since 2002 and been the most common cancer in Korean women since 2019. Of the newly diagnosed cases in 2019, 24,820 (83.5%) were of invasive carcinomas, and 4,909 (16.5%) were of carcinoma in situ. The median age of women with breast cancer was 52.8 years, and breast cancer was most commonly diagnosed in the age group of 40–49 years. The number of patients who have undergone breast conserving surgery has continued to increase since 2016, with 68.6% of patients undergoing breast conserving surgery in 2019. The incidence of early-stage breast cancer continues to increase, with stage 0 or I breast cancer accounting for 61.6% of cases. The most common subtype of breast cancer is the hormone receptor-positive human epidermal growth factor receptor 2-negative subtype (63.1%). The 5-year relative survival rate of patients with breast cancer from 2015 to 2019 was 93.6%, with an increase of 14.3% compared to that from 1993 to 1995. This report improves our understanding of breast cancer characteristics in South Korea.
RESUMEN
The cytological diagnosis of lymph node lesions is extremely challenging because of the diverse diseases that cause lymph node enlargement, including both benign and malignant or metastatic lymphoid lesions. Furthermore, the cytological findings of different lesions often resemble one another. A stepwise diagnostic approach is essential for a comprehensive diagnosis that combines: clinical findings, including age, sex, site, multiplicity, and ultrasonography findings; low-power reactive, metastatic, and lymphoma patterns; high-power population patterns, including two populations of continuous range, small monotonous pattern and large monotonous pattern; and disease-specific diagnostic clues including granulomas and lymphoglandular granules. It is also important to remember the histological features of each diagnostic category that are common in lymph node cytology and to compare them with cytological findings. It is also essential to identify a few categories of diagnostic pitfalls that often resemble lymphomas and easily lead to misdiagnosis, particularly in malignant small round cell tumors, poorly differentiated squamous cell carcinomas, and nasopharyngeal undifferentiated carcinoma. Herein, we review a stepwise approach for fine needle aspiration cytology of lymphoid diseases and suggest a diagnostic algorithm that uses this approach and the Sydney classification system.
RESUMEN
Objectives@#This study aimed to assess the status of the Journal of the Korean Academy of Child and Adolescent Psychiatry (JKACAP) and propose measures for its growth and development. @*Methods@#The study was conducted using a questionnaire survey targeting members of the Korean Academy of Child and Adolescent Psychiatry. The six key elements analyzed were Access to the journal, Convenience following conversion to English, Recognition as an international journal and institutional achievements, Author perspectives on manuscript submission,Transition to an online-only journal, and Content and identity of the journal. @*Results@#The survey revealed that email notification was highly effective for Journal Accessibility, with the website and search engines also frequently being used by members. Conversion to English in 2018 initially impacted readability and submission rates, but these concerns have decreased over time. However, the Recognition of JKACAP as an international academic journal was still not on par with SCIE journals, highlighting the need for further efforts towards SCIE inclusion. Despite these challenges and limited research opportunities, there was an active intention among members to submit manuscripts. Respondents showed a notable preference for the Transition to an online-only journal. Regarding content and identity of the JKACAP, members predominantly favored review articles and perceived the journal as a research and communication platform for Korean child and adolescent psychiatrists. @*Conclusion@#The results indicate the need for JKACAP to enhance its digital accessibility, provide more support for domestic and international authors, and actively seek SCIE indexing. Addressing the varied content preferences of its members, improving the submission process, and transitioning to an online-only format could further its growth and solidify its position as an internationally recognized academic journal in the field of child and adolescent psychiatry.
RESUMEN
Background@#Interleukin (IL)-17 and IL-23 inhibitors have helped achieve clear skin in many patients with psoriasis. However, real-world data to compare short- and long-term efficacy of these biologics in Korean patients are lacking. @*Objective@#To compare short- and long-term efficacy of IL-17A and IL-23 inhibitors in patients with moderateto-severe psoriasis. @*Methods@#We retrospectively evaluated efficacy of IL-17A and IL-23 inhibitors among patients treated at Ajou University Hospital from 2017 to 2022. The specific agents studied were as follows: secukinumab, 32 patients; ixekizumab, four patients; guselkumab, 13 patients; and risankizumab, 31 patients. Patients who were followed up for less than a year or changed biologics were excluded. @*Results@#The rates of psoriasis area and severity index (PASI) 90 achievement of secukinumab were 62.5%, 86.7%, 89.3%, 80.8%, and 70.8% at weeks 16, 40, 88, 112, and 136, respectively. For ixekizumab, the PASI90 achievement rates were 75%, 100%, 75%, and 100% at weeks 16, 40, 64, and 88, respectively. The PASI90 achievement rates of guselkumab were 53.8%, 76.9%, 72.7%, and 77.8% at weeks 20, 44, 68, and 92, respectively. For risankizumab, PASI90 achievement rates were 69.7%, 90.0%, 93.7%, and 100% at weeks 28, 52, 76, and 100, respectively. Before 52 weeks, PASI90 achievement was significantly lower with guselkumab than with secukinumab (hazardratio=0.22). After 52 weeks, PASI90 achievement was significantly higher with risankizumab than with secukinumab (hazard ratio=2.00). @*Conclusion@#PASI90 was achieved faster with IL-17A inhibitors than with IL-23 inhibitors. However, IL-23 inhibitors afforded the maintenance of a higher PASI score after 52 weeks.
