Rectal cancer, which accounts for approximately 40% of colorectal cancers, remains a major clinical concern. Recent advances in diagnostic imaging, surgical techniques, radiotherapy, and systemic treatment have steadily improved rectal cancer outcomes. Considering this, the Korean Rectal Cancer Multidisciplinary (KRCM) Committee has aimed to provide clinicians and policymakers with up-to-date, evidence-based clinical practice guidelines to support optimal decision-making, reflecting current evidence, the Korean healthcare context, and patient values and preferences. The Clinical Practice Guidelines for Rectal Cancer version 2.0 were developed through multidisciplinary collaboration with related academic societies, building upon and updating the KRCM Clinical Practice Guidelines version 1.0 (titled “Multidisciplinary guidelines for the management of rectal cancer”). These consensus guidelines of the KRCM were established based on a comprehensive literature review, evidence synthesis, with recommendation development guided by the GRADE (Grading of Recommendations Assessment, Development and Evaluation) methodology, and consideration of applicability in real-world clinical practice under the national health insurance system. Each recommendation has been presented with its strength and level of evidence.

Purpose: The career ladder system is a pivotal strategy for securing excellent nurses. The aim of this study is to understand hospital nurses’ experiences of participating in the career ladder system and to explore the essence of this system. Methods: In February 22 to March 3, 2022, nurses employed at a general hospital in South Korea were selected for this study using snowball and purposive sampling. Data were collected from interviews with three focus groups, the compositions of which are as follows: group 1, 6 participants; group 2, 5 participants; and group 3, 6 participants. All interviews were recorded, transcribed verbatim, and subsequently analyzed using qualitative research methods. Results: The following six categories were derived under the overall theme of “the arduous journey to discovering a nurse’s true name”: (1) rites of passage to becoming the ideal nurse; (2) unexpected challenges in the promotion preparation process; (3) biased criteria for evaluating nursing competencies; (4) unclear changes in roles and perceptions after promotion; (5) self-discovered pride and fulfillment as a nurse; and (6) the unspoken struggles of evaluators. Conclusion The findings suggest that the career ladder system fosters nurses’ professional growth and self-actualization. However, for effective implementation, nurses’ deep understanding and systematic management of the career ladder system are essential. This study offers valuable insights and benchmarks for healthcare institutions aiming to adopt the system.

Background: Poor outcomes after acute ischemic stroke (AIS) revascularization are anticipated in patients with dementia due to advanced age, comorbidities, and reduced disease awareness. This study investigated clinical characteristics and short-term outcomes of AIS revascularization in patients undergoing dementia treatment. Methods: We retrospectively reviewed patients who underwent AIS revascularization therapy at eight centers of the Catholic University of Korea. Patients receiving anti-dementia medication for cognitive impairment before stroke onset were analyzed. Clinical characteristics and outcomes, including the modified Rankin Scale (mRS) score, hemorrhagic transformation, and mortality, were collected. Results: Among 1,379 patients who received AIS revascularization over 5 years, 13 (0.94%; mean age 83 years; 8 females) had a preexisting diagnosis of dementia (Alzheimer’s disease in 11, mild cognitive impairment in 2) and were on anti-dementia medication. Two patients underwent intravenous thrombolysis combined with endovascular therapy, whereas 11 underwent endovascular therapy alone. Most patients (11/13, 84.6%) presented with an unclear onset time. Stroke lesions were located in the right middle cerebral artery (MCA) in seven cases, left MCA in three, bilateral MCAs in one, and posterior circulation in two. Hemorrhagic transformation occurred in six patients (46%), of whom three (23%) were symptomatic. The mRS scores at discharge were 6 in two patients, 5 in one patient, 4 in nine patients, and 3 in one patient. Four patients died within 3 months of stroke onset. Conclusion The proportion of patients with cognitive impairment receiving anti-dementia medication among those undergoing stroke revascularization therapy was very small. The rates of hemorrhagic transformation and mortality were high. None of the patients achieved favorable outcomes at discharge.

Background/Aims: Fecal microbiota transplantation (FMT) is a promising therapy for inducing and maintaining remission in patients with ulcerative colitis (UC). However, FMT has not been approved for UC treatment in Korea. Our study aimed to investigate patient perceptions of FMT under the national medical policy. Methods: This was a prospective, multicenter study. Patients with UC ≥ 19 years of age were included. Patients were surveyed using 22 questions on FMT. Changes in perceptions of FMT before and after education were also compared. Results: A total of 210 patients with UC were enrolled. We found that 51.4% of the patients were unaware that FMT was an alternative treatment option for UC. After reading the educational materials on FMT, more patients were willing to undergo this procedure (27.1% vs. 46.7%; p < 0.001). The preferred fecal donor was the one recommended by a physician (41.0%), and the preferred transplantation method was the oral capsule (30.4%). A large proportion of patients (50.0%) reported that the national medical policy influenced their choice of FMT treatment. When patients felt severe disease activity, their willingness to undergo FMT increased (92.3% vs. 43.1%; p = 0.001). Conclusions Education can increase preference for FMT in patients with UC. When patients have severe disease symptoms or their quality of life decreases their willingness to undergo FMT increases. Moreover, national medical policies may influence patient choices regarding FMT.

Hepatic dysregulation of lipid metabolism exacerbates inflammation and enhances the progression of metabolic dysfunction-associated steatotic liver disease (MASLD). STAT3 has been linked to lipid metabolism and inflammation. Jolkinolide B (JB), derived from Euphorbia fischeriana, is known for its pharmacological anti-inflammatory and anti-tumor properties. Therefore, this study investigated whether JB affects MASLD prevention by regulating STAT3 signaling. JB attenuated steatosis and inflammatory responses in palmitic acid (PA)-treated hepatocytes. Additionally, JB treatment reduced the mRNA expression of de-novo lipogenic genes, such as acetyl-CoA carboxylase and stearoyl-CoA desaturase 1. Interestingly, JB-mediated reduction in inflammation and lipogenesis was dependent on STAT3 signaling. JB consistently modulated mitochondrial dysfunction and the mRNA expression of inflammatory cytokines by inhibiting PA-induced JAK/STAT3 activation. This study suggests that JB is a potential therapeutic agent to prevent major stages of MASLD through inhibition of JAK/STAT3 signaling in hepatocytes.

Background: Adolescent unintended pregnancies can have detrimental effects on maternal and fetal health, impacting the social lives of young parents. Globally, there is an emphasis on preventing unintended pregnancies in adolescents through comprehensive contraceptive education. This study examined contraception practices and determinants among sexually active Korean adolescents. Methods: This study analyzed raw data from the 2018 and 2021 Korea Youth Risk Behavior Survey conducted by the Korea Disease Control and Prevention Agency. The cohort consisted of 6,042 adolescents who reported sexual experience, categorized into those always practicing contraception and those not. We scrutinized factors related to sexual behavior, such as contraception and sex education, as well as other social and behavioral factors. Results: Among sexually active adolescents, 47.9% of males and 48.1% of females consistently used contraception. The most prevalent contraceptive method was condoms (male 58.1%; female 59.6%). However, a significant portion of adolescents were not using contraception (male 29.4%; female 21.7%). Females who did not consistently use contraception exhibited higher pregnancy rates (2.4% vs. 11.3%). Consistent contraceptive users tended to live with their families and reported less sexual experience after drinking alcohol. Despite a decline in sexual education in schools from 2018 to 2021, the proportion of adolescents consistently using contraception increased. Conclusion To prevent unintended pregnancies among sexually active adolescents, consistent use of appropriate contraceptive methods is crucial.Comprehensive education on contraception should be extended beyond schools to include homes and primary healthcare settings. Policymakers and healthcare providers should consider these consequences when devising strategies to reduce unintended pregnancies among adolescents.
