Sparganosis is a rare parasitic infection caused by Spirometra species. Although it was relatively common in the past, it is now often overlooked. In this study, we review cases diagnosed through histopathological examination at a single institution in recent years to raise awareness of this neglected parasitic disease. Methods: We retrospectively analyzed cases of human sparganosis identified in the pathology archives of a single institution in South Korea between 2004 and 2025. A comprehensive review was conducted, including demographic data, clinical features, lesion locations, imaging findings, exposure history (such as dietary habits), and histopathologic findings. Results: A total of 15 patients were identified, including 10 females and 5 males, with a mean age of 65.1 years. Lesions were most commonly located in the lower extremities and breast. Imaging findings were largely nonspecific, with ultrasonography being the most frequently used modality. In most cases, clinical suspicion of sparganosis was absent, and excision was performed under the impression of a benign or malignant tumor. Histologically, variably degenerated parasitic structures were identified within granulomatous inflammation. However, preserved features such as calcospherules and tegumental structures facilitated definitive diagnosis. Conclusions: This study underscores the importance of recognizing the characteristic histopathological features of sparganosis, which can allow for accurate diagnosis even in the absence of clinical suspicion. Although rare, sparganosis remains a relevant diagnostic consideration in endemic regions, particularly in East Asia.

Objectives:
Ischemic stroke is influenced by long-term metabolic and renal deterioration; however, many risk prediction frameworks rely on single time-point measurements. We examined whether multi-period patterns in national health screening indicators are associated with incident ischemic stroke in Korea.
Methods:
Using customized National Health Insurance Service data with 3 biennial screenings (P1: 2013–2014; P2: 2015–2016; P3: 2017–2018), we identified incident ischemic stroke during 2019–2023 (Korean Standard Classification of Diseases-7 I63). After applying eligibility criteria and excluding individuals with missing screening values, we performed 1:1 propensity score matching on sex, 1-year age strata, and insurance type (97 454 matched pairs; n=194 908). Multi-period indicators included waist circumference increase ≥10%, sustained blood pressure ≥130/80 mmHg, sustained fasting glucose ≥126 mg/dL, proteinuria progression, and creatinine elevation in ≥2 periods (sex-specific thresholds). Associations were evaluated using conditional logistic regression; a comparator model used P3-only indicators.
Results:
In the multi-period model, stroke was associated with waist circumference increase ≥10% (odds ratio [OR], 1.05; 95% confidence interval [CI], 1.01 to 1.08), sustained blood pressure ≥130/80 mmHg (OR, 1.34; 95% CI, 1.31 to 1.37), sustained fasting glucose ≥126 mg/dL (OR, 1.66; 95% CI, 1.60 to 1.73), creatinine elevation in ≥2 periods (OR, 1.08; 95% CI, 1.06 to 1.10), and proteinuria progression (OR, 1.36; 95% CI, 1.32 to 1.39). In the P3-only model, all single-time-point indicators were associated with incident stroke (ORs, 1.08 to 1.47).
Conclusions
Multi-year patterns in metabolic screening indicators were associated with incident ischemic stroke. Repeated health screening measurements may complement single time-point assessments and support continuous risk-factor monitoring and patient-centered prevention.

Purpose:
This study examined the current status, perceptions, and educational needs of primary care education in medical and nursing schools to provide foundational data that can inform effective curriculum development.
Methods:
In total, 40 medical and 64 nursing schools were eligible for this study. Data were collected through an online survey using Google Forms, developed by the research team, from November 2024 to January 2025. Frequency analysis and independent t-tests were performed to compare perceptions on primary care education between the two schools types. Borich Needs Assessment and Locus-for-Focus model were used to identify and prioritize educational needs.
Results:
Responses from 21 medical and 24 nursing schools were analyzed. All medical schools primarily offered education in primary care clinics (100%), whereas most nursing schools offered it in community healthcare institutions (87.5%). Visits and observations were the most common educational methods (>80%). Reports, presentations, and discussions were the most used assessment methods (>60%). Multidisciplinary team-based practicums were limited in both medical (9.5%) and nursing (25.0%) schools. Both groups rated the need to expand primary care education and multidisciplinary team approach highly (>4.4/5). “Longitudinality” and “generalism” were educational priority needs across both groups, whereas other elements showed variations.
Conclusion
This study identified the shared and distinct aspects of primary care education across schools. The findings highlight the importance of enhancing and tailoring primary care education to each school’s specific context and needs, while fostering interprofessional collaboration to strengthen community-based healthcare.

Objectives:
This study aimed to examine the association between anticholinergic burden, cognitive function, and clinical severity in elderly patients with schizophrenia to suggest safer medication treatment strategies.
Methods:
A cross-sectional study was conducted with 60 patients aged 60-90 years diagnosed with schizophrenia according to Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition criteria at the National Center for Mental Health. Participants with Clinical Global Impression-Severity (CGS-S) scores ≤4 were included. The Korean Version of the Consortium to Establish a Registry for Alzheimer’s Disease assessment Packet, the 2nd Edition (CERAD-K), CGI-S, and total Anticholinergic Cognitive Burden (ACB) scores were assessed. Statistical analyses included Mann-Whitney tests, Bootstrap analysis of covariance, and Spearman correlations.
Results:
The mean age was 69.52±6.33 years, with 66.67% female participants. The mean total ACB score was 4.30±2.42, with 80% of patients having scores ≥3. High ACB group (n=48) showed significantly higher CGI-S scores (3.13±0.73 vs. 2.67±0.49, p=0.030) and lower performance in Word List Memory, Constructional Praxis, and Constructional Recall domains. After adjusting for education year, age, and sex, high ACB group showed significantly lower CERAD-K total score I than the low ACB group (F=5.947, p=0.018). Total ACB score also showed significant negative correlations with CERAD-K total score I (r=-0.32, p=0.011).
Conclusion
High anticholinergic burden in elderly schizophrenia patients was significantly associated with cognitive impairment and symptom severity. These findings suggest the need for careful medication adjustment in this population.

OBJECTIVES:
The coronavirus disease 2019 (COVID-19) pandemic had direct effects on population health through infection and morbidity, as well as indirect effects on population mental health. We estimated the network structure of post-traumatic stress symptoms (PTSS) and depressive symptoms throughout the pandemic in Korea and aimed to identify the most central and bridging symptoms.
METHODS:
Participants aged 30–64 years completed mental health surveys across 3 phases of the COVID-19 pandemic: March 2020 (n=1,925), February–March 2021 (n=1,754), and December 2021–January 2022 (n=1,595). Using PTSS and depressive symptom data, we conducted network analyses, and the primary measures of symptom importance (centrality) were expected influence and bridge expected influence.
RESULTS:
In the comorbidity network, although the most central symptoms fluctuated over the course of the pandemic, sleep problems were consistently identified as the most influential bridge symptoms throughout. The symptom network structure differed between the subacute and chronic phases of the pandemic.
CONCLUSIONS
We found evidence of changes in the network structure of PTSS and depressive symptoms, even as sleep problems retained a consistent role as a bridging symptom. Although overall network structures varied across phases of the pandemic, the bridging role of sleep-related symptoms remained consistently strong, suggesting that sleep problems may represent a general and enduring mechanism underlying PTSS–depression comorbidity. During future pandemics, prompt screening for sleep problems may help prevent the development of comorbidity between PTSS and depressive symptoms.

Objective:
To investigate the relationship between oral health, cognitive function, and quality of life (QoL) in elderly patients with schizophrenia.
Methods:
This cross-sectional study included 92 patients with schizophrenia, aged 60-90 years. Assessments included the Geriatric Oral Health Assessment Index (GOHAI), Consortium to Establish a Registry for Alzheimer’s Disease-Korean version, Schizophrenia Quality of Life Scale (SQLS), and Clinical Global Impression-Severity (CGI-S). Correlation and multiple regression analyses were performed.
Results:
GOHAI scores were significantly and negatively correlated with SQLS (r=-0.323) and CGI-S (r=-0.230). Multiple regression confirmed GOHAI as an independent predictor of SQLS (β=-0.325, p=0.001) after controlling for demographic and clinical variables. Furthermore, anticholinergic drug use did not significantly moderate the positive impact of oral health on QoL.
Conclusion
Improving oral health is directly associated with better subjective QoL in elderly patients with schizophrenia, independent of objective cognitive decline or anticholinergic burden. Integrated psychiatric-dental care is crucial for this population.
