Background: Given the dual potential of statins to act as both carcinogenic and antineoplastic agents, evidence from previous investigations into statin use and the risk of nonmelanoma skin cancer (NMSC) remains inconclusive. Objective: To demonstrate the impact of statin exposure on the NMSC risk in Korean patients. Methods: We carried out a multicenter cohort study based on electronic health record data aggregated from 11 Korean hospitals. Patients with hyperlipidemia who had been taking antilipidemic agents, including statins were included in this study. We applied 1:1 propensity score matching to create balanced cohorts and used Cox regression to assess the hazard ratio (HR) for NMSC. Results: A total of 18,579 statin users and a matched number of non-users were included across 11 databases. Statin use showed no significant association with an increased risk of NMSC (HR, 1.03; 95% confidence interval, 0.75–1.43). Subgroup analyses of drug exposure, age, and sex depicted no significant HR trends. Conclusion Statin exposure demonstrated no significant association with NMSC development in Korean patients with hyperlipidemia.

Background/Aims: Chronic constipation is prevalent yet under-diagnosed across Asia, compromising quality of life and burdening healthcare systems. Cultural stigma, varied diets, and limited access to standardized diagnostic tools delay timely care. Methods: The Bali Chronic Constipation Roundtable in November 2024, brought together experts from 11 Asian countries. The group reviewed epidemiological data, analyzed multinational questionnaire on clinical practice pattern, and conducted structured discussions to identify key barriers and propose region-specific recommendations. Results: Chronic constipation prevalence varies across Asia, ranging from 1.8% in India to 16.6% in Japan, with women and the elderly disproportionately affected. Under-reporting persists owing to cultural taboos and widespread self treatment with laxatives and traditional medications. Although the Rome IV criteria remains the global standard, they may not fully reflect Asian symptom profiles, and diagnosis is limited by scarce motility laboratories. First line therapies such as dietary-fiber optimization and osmotic laxatives are widely available, but newer pharmacotherapies (prucalopride, linaclotide, lubiprostone, and elobixibat) remain costly and unevenly accessible. Biofeedback for dyssynergic defecation is underutilized due to limited availability. Experts recommend expanded regional research on to refine diagnostic criteria, coupled with enhanced physician education and public awareness. They advocate accessibility to second-line and novel therapies that incorporate culturally attuned regional guidelines, and improved access to gastrointestinal motility testing. Conclusions The Bali Chronic Constipation Roundtable highlighted Asia’s need for region specific diagnostics and management. Addressing diagnostic and treatment gaps will improve outcomes, while ongoing researcher clinician policy collaboration must standardize guidelines, advance research, and ensure equitable care across Asia.

Methods: Retrospective study of 120 patients (223 fusion levels) who underwent ACDF between 2016 and 2021. Spacer types included structural allografts, PEEK, titanium, and ceramic cages. Radiographic measurements of subsidence were obtained from immediate (≤8 weeks) and long-term (≥6 months) postoperative lateral cervical radiographs. Multivariable linear regression was used to assess the association between spacer type and subsidence, adjusting for patient demographics, surgical levels, smoking history, and osteopenia. Results: The mean age of patients was 53.6±10.9 years and 41.7% were male; 47.5% had a smoking history and 20.8% had osteopenia. There were 38 one-level (31.7%), 61 two-level (50.8%), and 21 three-level fusions (17.5%). Spacer distribution included 62 structural allografts (51.7%), 27 PEEK (22.5%), 20 titanium (16.7%), and 11 ceramic (9.2%) cages. On multivariable analysis, PEEK cages were associated with significantly less anterior subsidence (β=−0.972, p <0.001) and posterior subsidence (β=−0.666, p=0.001) compared to allografts, and greater preservation of segmental lordosis (β=1.393, p=0.024). No significant differences in subsidence were found between titanium, ceramic, and allograft spacers. Conclusions PEEK cages showed reduced subsidence and better preservation of cervical lordosis compared to structural allografts, while titanium and ceramic cages did not differ significantly from structural allografts. These results suggest that PEEK cages may help minimize subsidence-related complications and improve outcomes.

Objective: To explain process of developing basic veterinary clinical performance guidelines, based on frequently observable clinical manifestations, thereby supporting competencybased veterinary education in Korea. Methods: A structured review of learning outcomes established by Korean Association of Veterinary Medical Colleges (KAVMC) was conducted by a planning committee including veterinary educators, practitioners, and advisory members. Owner-oriented descriptions were used to frame each performance task, and each was mapped to corresponding learning outcomes. These tasks were aligned with learning outcomes recommended by the KAVMC to support the development of communication, clinical reasoning, and performance-related competencies among veterinary students, thereby enhancing day-one clinical readiness. Results: In total, 63 clinical manifestations for a guidebook format that can be used for clinical education were identified and categorized by organ systems that are described in language understandable to animal owners. Conclusions and Relevance: The basic veterinary clinical performance guidelines based on common clinical manifestations would serve as a vital component in veterinary education to reinforce core graduation competencies.

Objective: This study aimed to compare aneuploidy rates and clinical outcomes between trophectoderm biopsy at fresh blastocyst (biopsy-fresh) followed by vitrification and biopsy at vitrified-warmed blastocyst (biopsy-vitri) followed by next day transfer (without re-vitrification). Methods: This retrospective study included 844 patients undergoing 844 cycles conducted from August 2019 to December 2023. Preimplantation genetic testing for aneuploidy (PGT-A) was performed via trophectoderm biopsy using array comparative genomic hybridization or next-generation sequencing for comprehensive 24-chromosome screening. Patients were divided into two groups based on the blastocyst status at the time of biopsy: the biopsy-fresh group (531 patients) and the biopsy-vitri group (313 patients). Results: The clinical pregnancy rate was significantly higher in the biopsy-fresh group compared to the biopsy-vitri group (58.7% vs. 45.6%; odds ratio [OR], 1.695; 95% confidence interval [CI], 1.215 to 2.364; p=0.002). Furthermore, the biopsy-fresh group showed higher implantation rates (45.6% vs. 32.1%; OR, 1.767; 95% CI, 1.274 to 2.451; p=0.002), ongoing pregnancy or live birth rates per cycle (48.0% vs. 35.8%; OR, 1.652; 95% CI, 1.177 to 2.319; p=0.004), and rates of good-quality blastocysts (57.1% vs. 32.1%, p<0.001) compared with the biopsy-vitri group. Miscarriage rates did not differ significantly between the groups (18.2% vs. 21.4%; OR, 0.818; 95% CI, 0.457 to 1.465; p=0.501). Conclusion Biopsy at fresh blastocyst demonstrated superior clinical outcomes compared with biopsy at vitrified-warmed blastocyst, likely due to better embryo quality. Both biopsy at fresh blastocyst and vitrified-warmed blastocyst remain viable options for PGT-A, with biopsy at vitrified-warmed blastocyst serving as a practical alternative. Embryo quality and euploid status continue to be critical considerations for embryo transfer selection.

Dementia is a neuropsychiatric disorder that primarily affects the elderly, leading to a widespread decline in cognitive function and significant impairment of occupational, social, and personal functioning. In addition to cognitive deficits, dementia is frequently comorbid with behavioral and psychological symptoms of dementia (BPSD), such as agitation.When present, these secondary symptoms can exacerbate the clinical course of the disease, reduced treatment responsiveness, increased rates of admission to long-term care facilities, extended hospitalization, higher risk of personal injury and a substantial socioeconomic burden. Given these consequences, early management of BPSD—particularly agitation—is critical to mitigating these risks. Although antipsychotics are commonly prescribed to manage agitation, risperidone remains the only agent approved by regulatory authorities for this indication. Recently, however, brexpiprazole, a medication with a pharmacological profile distinct from that of risperidone, received U.S. FDA approval (on May 11, 2023) for the treatment of agitation associated with Alzheimer’s disease. Agitation is among the most prevalent BPSD manifestations, with symptoms ranging from verbal to physical aggression. Given its recent approval and unique pharmacodynamic properties, brexpiprazole may have strong potential as a therapeutic option for this population. This paper aims to review the pharmacological mechanisms, clinical evidence, and future perspectives of brexpiprazole as a novel therapeutic option for managing agitation in patients with Alzheimer’s disease.

Objective: Recognizing discrimination as a significant public health risk during the coronavirus disease 2019 (COVID-19) pandemic, which coincided with increased drug use and heightened awareness of structural disparities in the United States, we investigated its association with the odds of drug use in a large and diverse cohort from the All of Us Research Program. Methods: In this cross-sectional study, data from 68,976 participants completed the COVID-19 participant experiences (COPE) survey. We applied logistic regression models with propensity score-based overlap weighting to examine associations between everyday discrimination and drug use. Self-reported everyday discrimination score and drug use were the primary exposure and outcome measures, respectively. Results: Of the 67,662 COPE respondents (mean [standard deviation] age, 57.5 [15.9] years; female sex at birth, 43,658 [64.5%]), we identified 15,493 participants with no reported discrimination and 15,493 participants with reported discrimination, after overlap weighting. The odds of drug use in those who reported discrimination was 1.38 (95% confidence interval, 1.32–1.43), with a dose-dependent association based on discrimination score. Participants who experienced discrimination had significantly higher odds of using drugs and this association was particularly pronounced in those under 40 years of age, those assigned female sex at birth, current smokers, individuals undergoing chemotherapy or immunotherapy, and those experiencing unemployment or COVID-19/flu-like symptoms. Conclusion This relationship was observed across various types of drugs and different reasons for discrimination, and it was particularly pronounced in specific subgroups. These findings provide critical evidence for developing targeted preventive interventions; however, further longitudinal studies for causality are warranted.
