Background: The prognosis of end-of-life patients is challenging, and clinicians have attempted to predict survival more accurately. High serum creatinine (sCr) levels are associated with lower survival rates in patients with various cancers; however, low sCr levels are commonly expected in patients with terminal cancer because of muscle wasting and malnutrition. Therefore, we investigated the prevalence of low and high sCr levels and their association with survival duration in patients with terminal cancer in a palliative care unit. Methods: We analyzed the medical records of 280 patients admitted to a palliative care unit. Patients were divided into low (<0.5 mg/dL), normal (0.5–1.2 mg/dL), and high (>1.2 mg/dL) sCr groups. Kaplan-Meier survival curves using sCr levels were plotted and compared using the log-rank test. Using stepwise selection, a multivariable Cox proportional hazards model was used to identify the significant prognostic factors. Results: The median survival durations in the high-, low-, and normal-sCr groups were 9.57 days, 22.26 days, and 27.51 days, respectively. Multivariable Cox proportional hazard model identified that males (hazard ratio [HR], 1.81; 95% confidence interval [CI], 1.16–2.85), poor performance status (HR, 3.43; 95% CI, 1.12–10.54), total parenteral nutrition use (HR, 1.84; 95% CI, 1.09–3.1), high sCr (HR, 2.74; 95% CI, 1.52–4.94), and low sCr (HR, 1.22; 95% CI, 1.07–1.43) were significantly associated with a shorter survival time. Conclusion Low and high serum creatinine levels were significantly associated with poor survival in patients with cancer at the end-of-life stage. Therefore, readily available and simple biomarkers may help plan advanced care in palliative care settings.

Background: Although numerous studies examined the association between obesity and colorectal cancer, comparatively less research has focused on the relationship between weight change and physical activity. Methods: This study used health check-up data from the National Health Insurance Service. Participants aged 20–79 years who underwent health check-ups between 2004 and 2007 and again 10 years later were included. Differences were analyzed by dividing the weight change into groups that increased or decreased by 5%, 5%–20%, and 20% or more. Results: Among men, a 5%–20% increase in body weight was significantly associated with a higher risk of colon cancer (hazard ratio [HR], 1.26; 95% confidence interval [CI], 1.05–1.52), even among those who exercised on at least 3 days a week. In contrast, women who had undergone a weight loss of more than 20% of their body weight were found to have a significantly reduced risk of colon cancer (HR, 0.69; 95% CI, 0.50–0.93). However, women who reduced their exercise frequency from 3 or more days per week to less than 3 days per week experienced a weight gain of 20% or more, which was associated with a higher risk of developing colorectal cancer (HR, 1.82; 95% CI, 1.07–3.12). Conclusion These findings highlight the association between recent increases in colon cancer incidence and weight management, emphasizing the importance of maintain a healthy weight in mitigating obesity-related cancer risk.

Primary care is a key component in building an efficient and sustainable healthcare system, providing comprehensive health management through a patient-centered approach. Countries worldwide continue to reform their primary care systems to enhance their effectiveness within diverse healthcare environments and socioeconomic contexts. Among them, Australia is recognized for its well-established primary care system. It provides universal health coverage through Medicare. General practitioners offer comprehensive medical services and play a pivotal role in Australia’s primary care system. To further support primary care, the Primary Health Networks (PHNs), a community-based medical service network, has been established. However, challenges remain, such as a shortage of workforce shortages and regional disparity in medical resources. To address these issues, the Australian government announced the “Primary Health Care 10 Year plan.” Through the efforts, Australia is expected to further strengthen its primary care system.

Kimura’s disease is a rare, chronic inflammatory disorder that typically presents as painless head and neck masses in young Asian males, often accompanied by peripheral eosinophilia and elevated IgE levels. We report a case of recurrent Kimura’s disease involving the right parotid gland in a 35-year-old man, previously treated surgically. Due to tumor size (6 cm) and high risk of surgical complications, the patient underwent radiotherapy (30 Gy/15 fractions). Post-treatment imaging showed significant tumor reduction with no adverse effects or recurrence during 12 months of follow-up. While surgery remains the mainstay of treatment, recent studies suggest that radiotherapy or immunosuppressive therapy may be effective, especially in cases at high risk of recurrence. A recent meta-analysis identified tumor size ≥3 cm, prolonged disease duration (5 years), high eosinophil percentage (20%), and elevated IgE (10,000 IU/ml) as significant recurrence predictors. This case supports that radiotherapy may sere as a valuable treatment option when surgery in contraindicated or in high-risk recurrent cases.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection contribute to platelet activation and thrombus formation. Severe coronavirus disease 2019 (COVID-19) is characterized by an increased risk of thromboembolic events that can lead to adverse outcomes in patients with severe disease manifestations. We present the case of a 41-year-old man who died from a pulmonary embolism and review the connection between SARS-CoV-2 infection, increased platelet counts, and the resulting fatal thrombosis. Total knee replacement surgery was performed and the patient was able to ambulate for a few days postoperatively. The platelet count exceeded the upper limit between postoperative days six and nine, reaching 708,000/μL on day 20. SARS-CoV-2 was confirmed 14 days after surgery, and the patient died 23 days after surgery while hospitalized. Autopsy revealed a fatal pulmonary embolism and deep vein thrombosis. If blood clots are caused by increased platelet counts due to COVID-19, it is essential to understand this relationship and prepare for complications that may arise after infection. Several recent studies have shown a link between COVID-19 and coagulation. We propose several considerations for autopsies of unexpected fatal pulmonary embolism during the SARS-CoV-2 endemic period.

Purpose: This study analyzed the career paths of medical school graduates in the Daejeon, Sejong, and Chungcheongnam-do (DSC) region of South Korea, focusing on career choice factors at each career path. The ultimate goal was to derive practical insights to improve career guidance in the medical field and enhance professionalism. Methods: Data were collected through in-depth interviews with 10 medical school graduates working in the DSC region. A semi-structured questionnaire was used to explore their career paths, and factors influencing their career decisions. The collected qualitative data were analyzed using the constant comparative method to identify themes and categories. Results: The study results categorized career stages into three phases: “entering medical school,” “choosing a specialty after graduation,” and “choosing a workplace after training.” Career choice factors were classified into “personal factors,” “social factors,” and “job and work environment factors.” The factors influencing career choices differed across each career path. Conclusion This study holds significance in its in-depth analysis of career choice factors across different career paths from a long-term perspective. The findings suggest that effective support for career decision-making in the medical field requires a tailored approach that considers the distinct needs and influencing factors at each career path.

Purpose: With the accelerated adoption of artificial intelligence (AI) in medicine, the integration of AI education into medical school curricula is gaining significant attention. This study aimed to gather the perceptions of faculty members and students regarding the integration of AI education into medical curricula in the Korean context. Methods: Faculty members and medical students’ perspectives on integrating AI into medical curricula were assessed through thematic analysis of free-written responses from 157 faculty members and 125 students in a national online survey on medical AI competencies in South Korea. Results: Three key themes emerged: content, which prioritizes basic knowledge and its practical applications, with an emphasis on ethical and legal responsibilities; curricular design, which advocates for a spiral curriculum tailored to learners' needs; and concerns, which highlight balancing AI integration with the principal goals of medical education while critically evaluating ongoing advancements. Conclusion Our study adds valuable insights into the content and methods to prioritize AI education. Given the rapid evolution of medical learners and AI technologies, continuous and timely needs assessment for AI curriculum development is crucial to maintain relevance and effectiveness.

Objectives: Maternal depression negatively affects depression and anxiety symptoms in the offspring. This study examined the association between maternal depression and their adolescent offspring depression and anxiety, as well as the mediating role of emotional trauma in determining the association. Methods: Participants were 237 mothers (46.08±5.00 years) and their adolescent offspring (16.54±1.51 years). The participants completed the Beck Depression Inventory-II, Early Trauma Inventory Self Report-Short Form, Center for Epidemiological Studies Depression Scale for Children, and the Screen for Children’s Anxiety Related Disorders. The mediating effect of emotional trauma on offspring was explored using mediation analysis. Results: Maternal depressive symptoms were significantly correlated with adolescent offspring traumatic experiences, as well as with their depressive and anxiety symptoms. Mediation analysis results showed that emotional trauma of offspring significantly mediated the effect of maternal depression on their depressive and anxiety symptoms. Conclusion Findings indicate that maternal depression was significantly associated with depressive and anxiety symptoms in adolescent offspring, mediated by their emotional trauma. Future research is needed to investigate pathways and intervention strategies to prevent the intergenerational transmission of emotional problems.
