Janus kinase (JAK) inhibitors are an important treatment option for ulcerative colitis, providing rapid onset of action, oral administration, and efficacy even after biologic failure. The 3 approved agents—tofacitinib, filgotinib, and upadacitinib—differ in JAK isoform selectivity, leading to clinically meaningful differences in efficacy and safety. Evidence from network meta-analyses, clinical trials, and real-world studies consistently shows that upadacitinib provides the highest efficacy for induction and maintenance of remission, whereas filgotinib demonstrates the most favorable safety profile. The strong efficacy of upadacitinib and tofacitinib is particularly relevant in patients with severe disease, including acute severe ulcerative colitis, and upadacitinib maintains high efficacy regardless of prior advanced therapy exposure. JAK inhibitors also benefit extraintestinal manifestations. Although risks such as herpes zoster, serious infection, thromboembolism, and major cardiovascular events differ among agents, long-term data suggest generally acceptable safety when used appropriately. Intraclass JAK-to-JAK cycling is feasible, with about half of patients achieving steroid-free clinical remission in retrospective cohorts. Based on mechanistic, clinical, and real-world evidence, filgotinib may be a first-line option for patients with lower disease activity or when safety is a priority, whereas upadacitinib or tofacitinib may be preferred in higher disease activity. Strategically selecting agents may improve durability and outcomes.

With a solitary remaining tooth in the mandible, restoration with a conventional removable partial denture is often associated with insufficient retention, support, and stability, as well as excessive stress concentration on the remaining tooth, leading to an unfavorable prognosis. Recently, treatment plans involving the placement of a small number of strategically positioned implants to fabricate removable partial dentures have been adopted to overcome these limitations.The use of implant surveyed crowns is considered to offer superior long-term outcomes compared with implant attachments. This report describes the restoration of a partially edentulous mandible with a single remaining tooth using an implant-assisted removable partial denture assisted by a surveyed fixed partial denture following bilateral posterior implant placement, achieving favorable clinical results.

Cervical foraminal lipoma is a rare cause of cervical radiculopathy. We report the case of a 47-year-old woman who presented with a 1-year history of right arm pain and paresthesia that was refractory to conservative treatment. Magnetic resonance imaging demonstrated a well-defined mass within the right C5-6 neural foramen, causing compression of the exiting C6 nerve root. The patient underwent microsurgical excision via posterior cervical laminoforaminotomy. Intraoperatively, a lipomatous mass compressing the nerve root was identified and completely removed. Histopathological examination confirmed a benign lipoma. Postoperatively, the patient experienced marked symptomatic improvement, with no recurrence of symptoms at a 6-month follow-up. Although it is uncommon, cervical foraminal lipoma should be considered in patients with persistent radiculopathy and atypical imaging findings, and surgical excision can provide favorable clinical outcomes.

OBJECTIVES:
Individuals with disabilities are at greater risk of hospitalization than the general population. We examined 10-year trends in potentially preventable hospitalizations (PPH) in Korea, comparing individuals with and without disabilities and assessing age-specific patterns.
METHODS:
Using National Health Information Database claims data (2010–2019), we established a fixed cohort of newly registered individuals with disabilities and control subjects statistically matched (1:1.5) at baseline. Annual PPH rates among patients with each condition were calculated and age- and sex-standardized according to Organization for Economic Cooperation and Development Health Care Quality Indicators definitions. Trends and annual percent changes (APCs) were analyzed by disability status and age group (non-older: 30–64; older adults: ≥65 years).
RESULTS:
Between 2010 and 2019, PPH rates declined significantly in both groups. Among individuals with disabilities, the steepest decline was observed for hypertension (APC, −15.7%; 95% confidence interval [CI], −17.7 to −13.7), whereas congestive heart failure showed the largest reduction among individuals without disabilities (APC, −7.8%; 95% CI, −10.8 to −4.7). Declines were generally greater among non-older adults aged 30–64 years, regardless of disability status. The disparity between disability and non-disability groups narrowed over the decade, primarily due to larger improvements among non-older adults. Older adults with disabilities consistently exhibited the highest PPH rates for most conditions, whereas younger individuals with disabilities had the highest rates for diabetes.
CONCLUSIONS
PPH rates declined over the decade among both individuals with and without disabilities, particularly for hypertension and among non-older adults. However, older adults with disabilities remain at elevated risk, underscoring the need for targeted strategies to improve access to community-based primary care.

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.

This study aimed to investigate sleep quality and the fear of falling among community- dwelling older women living alone and to identify the factors influencing the fear of falling. Methods: This descriptive correlational study included 178 community-dwelling older women living alone. Data were collected from December 10, 2023, to February 29, 2024. The collected data were analyzed using t-tests, analysis of variance, Pearson’s correlation coefficients, and hierarchical multiple linear regression. Results: The results of this study showed that age (β=.29, p<.001), community activity (β= -.23, p<.001), depression (β=.29, p<.001), social participation (β=-.18, p=.004), and sleep quality (β=.37, p<.001) were significantly associated with the fear of falling. Conclusion: Identifying the factors influencing the fear of falling, including sleep quality, among community-dwelling older women living alone highlights the need to develop preventive programs tailored to the characteristics of this population.

Menopause is a normative midlife transition characterized by profound endocrine remodeling and a high burden of symptoms and functional change. Accumulating epidemiologic and translational evidence links menopausal transition with shifts in cardiometabolic risk, musculoskeletal health, sleep, mood, and perceived cognitive function. However, most data support association rather than definitive causal acceleration of aging independent of chronological time. This narrative review proposes a menopause-centered healthspan framework that integrates biological, neurocognitive, and psychosocial domains and translates evidence into pragmatic clinical pathway tools. To inform topic selection and prioritize higher-level evidence, including guidelines, randomized trials, meta-analyses, and large cohort studies, a structured evidence scan utilizing PubMed and targeted citation tracking was performed. The evidence scan identified 256 citations. After duplicate removal, titles/abstracts of 162 unique records were reviewed, of which 102 citations informed the final narrative synthesis. The results emphasize that menopausal hormone therapy remains the most effective treatment for vasomotor symptoms and an evidence-based option for reducing fracture risk in appropriate candidates. However, it is not indicated for the primary prevention of cardiovascular disease or dementia. Absolute risks and benefits vary by age, time since menopause, and formulation/route. The neurocognitive section distinguishes common, often transient midlife cognitive complaints from long-term neurodegenerative outcomes, highlighting that menopause is not established as an independent dementia risk factor in the general population. Overall, the framework aims to support individualized, equity-informed care during menopausal transition.

Probiotics have gained increasing clinical attention as adjunctive treatment for lower gastrointestinal disorders. However, evidence supporting their therapeutic efficacy remains limited, particularly with regard to sex-related differences. This expert review provides evidence-based insights and practical recommendations for the use of probiotics in patients with irritable bowel syndrome (IBS), functional constipation (FC), and Clostridioides difficile infection (CDI), considering possible sex-related differences. Evidence from randomized controlled trials and meta-analyses indicates that probiotics can modestly improve global symptoms, abdominal pain, and bloating in IBS and enhance bowel movement frequency and stool consistency in FC. However, these effects are strain-specific and heterogeneous. Although clinical studies on probiotics in IBS have not confirmed significant sex-related differences, experimental animal studies using stress-induced IBS models have demonstrated sex-dependent responses to specific probiotic strains, supporting the biological plausibility of such differences. For CDI, the efficacy of probiotics in preventing primary or recurrent infections remains inconsistent across large trials, and current guidelines usually do not recommend their routine use. However, sex and age difference of immunology supports the clinical differences of CDI. Probiotics are generally considered safe for healthy individuals, although caution is advised in patients who are immunocompromised or critically ill. Clinicians should select probiotic products based on strain-specific clinical evidence, adequate viable doses, patient's characteristics, or patient’s sex. In conclusion, probiotics might play a role as adjunctive therapy for IBS and FC, with variability in responses influenced by microbial, host, and potential sex-related factors. Further research is needed to establish optimized personalized probiotic strategies.

Journal of Neurogastroenterology and Motility 2026;32(1):86-98
Background/Aims:
Spinal cord injury (SCI) frequently impairs defecation, severely affecting the quality of life. This study examines compensatory neural remodeling after SCI, focusing on basal colonic contractility, neural responses to electrical field stimulation, and alterations in excitatory cholinergic and inhibitory nitrergic pathways.
Methods:
Female Sprague–Dawley rats underwent either sham surgery or T10 spinal cord transection and were categorized into 3 groups: sham, 1-week post-SCI (acute), and 4-week post-SCI (chronic). Colonic contractility was assessed in an organ bath using electrical field stimulation in the presence of a nitric oxide synthase inhibitor. Neural protein expression was analyzed by immunofluorescence and Western blotting.
Results:
SCI produced region- and time-dependent impairments in colonic contractility, with distinct alterations in the proximal circular and longitudinal muscles across acute and chronic phases. Neural excitability shifted dynamically, showing enhanced excitatory activity in the proximal longitudinal muscle at 1-week and the distal circular muscle at 4-week post-SCI. Protein analysis revealed increased neuronal nitric oxide synthase in the proximal colon, decreasedsoluble guanylyl cyclase in the distal colon, upregulated muscarinic M3 receptor in the proximal colon, and reduced vaso-active intestinal peptide receptor 1 in both proximal and distal regions.
Conclusion
SCI induces spatiotemporal remodeling of excitatory and inhibitory neural pathways, contributing to colonic dysmotility and revealing potential targets for therapeutic intervention.
