Hereditary cancer: Germline testing practices across ERN GENTURIS member countries.

Germline genetic testing practices for hereditary cancer vary across the European Reference Network on Genetic Tumour Risk Syndromes (ERN GENTURIS) member countries. We surveyed experts in genetic testing from 20 EU member countries and Norway to assess multi-gene panel usage, availability of genome-wide sequencing, first-tier testing approaches, implementation of polygenic risk scores, and the roles of non-genetic healthcare professionals. National experts and members of the ERN GENTURIS completed a structured questionnaire covering founder germline pathogenic variants (gPV) testing, panel testing for common genetic tumour risk syndromes, use of whole-exome sequencing (WES) and whole-genome sequencing, polygenic risk score implementation, use of formalin-fixed paraffin-embedded tumour samples, laboratory accreditation, and the clinical roles of physicians, genetic counselors and nurses. Significant inter-country heterogeneity was observed. Most countries rely on next-generation sequencing (NGS) multi-gene panels. Founder gPV testing is first-line in a few high-prevalence populations (e.g., BRCA1/2 founders). All 21 countries offer NGS panel tests for hereditary breast and ovarian cancer, and ≥19 countries do so for colorectal and prostate cancers. However, NGS panel size and gene composition exhibit substantial variability. WES is available in 12 countries on a routine basis. Most countries implemented genetic testing on stored tumour tissue from deceased patients. In all countries, clinical geneticists can order germline genetic tests, and in 9 countries, any physician can do so. These findings show differences in accessibility to germline genetic testing of hereditary cancer in Europe. We propose EU-wide guidance via pathways, standards of care, and sharing of best practices to further optimize access to hereditary cancer genetic molecular diagnostics.

Comprehensive functional testing in fibroblasts has strong utility to diagnose mitochondrial disease.

Genome sequencing is the first-line diagnostic method for primary mitochondrial diseases (PMDs), yet its effectiveness is limited by variants of uncertain significance or unresolved genetic findings. We systematically evaluated the clinical performance of fibroblast-based functional testing, comprised of respiratory chain enzyme assays, blue native polyacrylamide gel electrophoresis with in-gel activity staining (BN-PAGE), complex I assembly assay, and targeted protein abundance assessments, in a cohort of 204 genetically confirmed PMD patients, 51 healthy controls, and 53 patients with differential diagnoses. Individually, enzyme assays, BN-PAGE, and complex I assembly assay showed sensitivities of 46%, 40%, and 49%, with specificities of 93%, 98%, and 99%, respectively. Combined, the assays achieved an overall sensitivity of 76%, a specificity 93%, a positive predictive value 96%, and a negative predictive value of 67%. Sensitivity was highest for isolated respiratory chain deficiencies, nuclear DNA-encoded mitochondrial translation defects, cofactor deficiencies, and mitochondrial aminoacyl-tRNA synthetase disorders, whereas mitochondrial DNA variants and maintenance defects remained challenging. Secondary mitochondrial dysfunction was rare. The strong clinical utility of comprehensive fibroblast functional testing improves PMD diagnosis when used complementary to genomic sequencing.

Diagnostic and clinical utility of exome sequencing and chromosomal microarray in children with GDD/iD: a meta-analysis.

BACKGROUND: Global developmental delay/intellectual disability (GDD/ID) is among the most common neurodevelopmental disorders, with up to half of cases are attributed to genetic factors. Chromosome microarray (CMA) has traditionally been the primary genetic test for idiopathic GDD/ID. However, whole exome sequencing (WES) and whole genome sequencing (WGS) have recently emerged, substantially increasing diagnostic yields in these populations. METHODS: We conducted a comprehensive literature search of PubMed, Scopus, EMBASE, and the Cochrane Library from inception to April 29, 2025. Studies reporting the diagnostic utility of these tests in children with GDD/ID were included and analyzed. RESULTS: A total of 102 studies, comprising 55,752 children, were reviewed. The pooled diagnostic yield of WES was 0.37 (95% CI: 0.33-0.41; I2 = 93%), significantly higher than that of CMA at 0.19 (95% CI: 0.16-0.21; I2 = 95%). Subgroup analyses showed that WES yielded significantly higher diagnostic rates than CMA in both same-sample comparisons (OR = 2.27, 95% CI: 1.08-4.78) and different-sample comparisons (OR = 1.65, 95% CI: 1.15-2.37). Only one study evaluated WGS, reporting a diagnostic yield of 0.27. Meta-regression revealed a significant association between CMA diagnostic yield and the proportion of male participants (p < 0.01), but not with WES. No significant difference in diagnostic utility was observed between isolated GDD/ID and GDD/ID with comorbidities. CONCLUSION: In children with unexplained GDD/ID, WES demonstrates superior diagnostic and clinical utility compared to CMA. Incorporating WES as a first-line investigation in the diagnostic evaluation of GDD/ID may be warranted.

Incidence of silent cerebral lesions during pulsed field ablation for paroxysmal atrial fibrillation.

BACKGROUND: Radiofrequency catheter ablation (RFCA) is a first-line treatment for paroxysmal atrial fibrillation (PAF). Complications such as silent cerebral lesion (SCL) may occur during ablation. Pulsed field ablation (PFA) is a non-thermal method thatablates cardiac tissue via irreversible electroporation. Limited studies have reported the incidence of SCL during PFA, with highly variable results. However, randomized controlled trials (RCTs) remain scarce. The objective of this study was to compare perioperative SCL incidence between PFA and RFCA, and to identify risk factors for SCL during PFA. METHODS: In this prospective pilot RCT (ChiCTR2400088774), 62 patients with PAF were randomized 1:1 to undergo PFA or RFCA. Cerebral MRI (3.0 T) was performed preoperatively and 24-48h postoperatively. SCL was defined as a new acute brain lesion on MRI without neurological deficits. Baseline and surgical data of the patients were collected. RESULTS: SCL was detected post-procedure in 6.45% (2/31) in the RFCA group, 12.90% (4/31) in the PFA group. No statistically significant difference in the incidence of postoperative SCL was detected between the two groups (p = 0.67). Left atrium dimension (LAD), left atrial operation time (LAOT), left ventricular end-diastolic dimension (LVEDD), and total operation time (TOT) were significantly higher in SCL group than those in no-SCL group (p < 0.05) through univariate analyses. CONCLUSIONS: SCL incidence was 12.90% in the PFA group versus 6.45% in the RFCA group. While no statistically significant difference was detected between two groups, the numerically higher rate in the PFA group warrants larger studies to evaluate cerebral safety associated with PFA.

Comparison of Keverprazan-based versus esomeprazole-based dual therapy for initial treatment of Helicobacter pylori infection: a prospective, multicenter, randomized controlled trial.

BACKGROUND: Keverprazan offers a new perspective for Helicobacter pylori eradication. This study compared 14-day keverprazan-amoxicillin therapy with esomeprazole-amoxicillin therapy to explore a superior treatment strategy. METHODS: This was a prospective, open-label, multicenter, randomized controlled trial in adult patients with treatment-naive H. pylori infection. Participants were randomly assigned to receive either 14-day of KA therapy (Keverprazan 20 mg b.i.d plus amoxicillin 1 g t.i.d) or 14-day of EA therapy (Esomeprazole 40 mg b.i.d plus amoxicillin 1 g t.i.d). The primary outcome was the H. pylori eradication rate. Secondary outcomes were the incidence of adverse events and patient adherence. RESULTS: A total of 264 patients were enrolled in the study. In the intention-to-treat (ITT) analysis, the eradication rates for the 14-day KA group and the 14-day EA group were 87.9% and 80.3%, respectively (p = 0.092); in the modified intention-to-treat (mITT) analysis, the eradication rates were 92.1% and 86.2%, respectively (p = 0.135); and in the per-protocol (PP) analysis, the eradication rates were 93.5% and 88.3%, respectively (p = 0.155). Non-inferiority was confirmed between the two groups (all p < 0.001). Adverse events and patient adherence were similar between the two groups. CONCLUSION: For treatment-naive H. pylori infection, the 14-day KA therapy is non-inferior to EA therapy. Given its good tolerability, pharmacogenomic independence, and potent acid suppression, KA is a rational first-line alternative to EA in the Chinese population.

Efficacy and safety of JAK inhibitors for vitiligo: an updated systematic review and meta-analysis of randomized controlled trials.

Purpose: Janus kinase (JAK) inhibitors are a promising therapeutic option for vitiligo, but previous meta-analyses have focused mainly on topical ruxolitinib versus placebo. Newer randomized controlled trials (RCTs) evaluating oral agents and head-to-head comparisons with active treatments have not been comprehensively synthesized. Materials and methods: We searched PubMed, Embase, the Cochrane Library, and Web of Science to 11 March 2026. Eligible RCTs evaluated JAK inhibitor monotherapy versus placebo or active comparators. Two reviewers screened records, extracted data, and assessed risk of bias using RoB 2.0. The primary outcome was F-VASI75. Meta-analyses used fixed-effect or random-effects models. GRADE assessed certainty of evidence. Results: Nine RCTs (1826 patients) were included. JAK inhibitors increased F-VASI75 versus placebo (RR 4.59, 95% CI 3.20-6.59; p < 0.001). For F-VASI50, they were superior to tacrolimus (RR 1.88, 95% CI 1.02-3.45) but not significantly different from dexamethasone (RR 2.17, 95% CI 0.95-4.94). Serious adverse events were comparable between groups (RR 1.15, 95% CI 0.57-2.33). Evidence certainty was moderate. Conclusions: JAK inhibitors are effective and well tolerated for vitiligo. Topical ruxolitinib is supported as a first-line option for limited facial disease; oral agents show promise but require longer-term safety data.

A Randomized Clinical Trial to Compare Moxifloxacin Versus Azithromycin for the Treatment of Mycoplasma genitalium: The FARTHEST Study.

BACKGROUND: Mycoplasma genitalium (MG) is increasingly characterized by high rates of macrolide and fluoroquinolone resistance. International guidelines recommend resistance-guided therapy; however, access to genotypic testing is limited, and randomized trial evidence is lacking. We assessed the efficacy of moxifloxacin and azithromycin without resistance assays. METHODS: This monocentric, open-label, superiority, randomized controlled trial enrolled adults with MG infection detected by multiplex PCR, randomized 1:1 to receive moxifloxacin 400 mg daily for 10 days or azithromycin 500 mg daily for 6 days. A test of cure was performed ≥28 days after treatment completion. The primary endpoint was microbiological cure in the intention-to-treat (ITT) and per-protocol (PP) populations. Subgroup analyses assessed symptomatic versus asymptomatic infections, doxycycline exposure, re-treatment, and sexual behavior. RESULTS: Among 358 randomized participants, 87.0% of those treated with moxifloxacin and 61.2% of those treated with azithromycin achieved microbiological cure in the ITT analysis (absolute risk difference 25.8%, 95% CI 16.5, 35.2). The superiority of moxifloxacin was confirmed in the ITT and PP populations. Moxifloxacin remained superior across most subgroups, whereas azithromycin showed comparable efficacy only among heterosexual individuals. Doxycycline coadministration did not improve outcomes. Both regimens were well tolerated, with only one case of discontinuation. CONCLUSIONS: Moxifloxacin demonstrated superior efficacy compared to azithromycin for treating MG infection in the absence of resistance testing. These randomized data support the use of moxifloxacin as a first-line option when resistance assays are unavailable and may inform treatment strategies.

A phase II study to evaluate the efficacy of commercially available molecularly matched targeted therapies in the second-line setting.

BACKGROUND: Initial studies have shown improved outcomes in patients receiving cancer therapies matched to their molecular alterations. To improve the chances of finding a therapeutic match for patients, this study evaluated the preliminary antitumor activity of 3 commercially available multitargeted agents in the United States, regorafenib, afatinib, and cabozantinib. METHODS: In this phase II trial, patients who did not benefit from first-line treatment for non-small cell lung cancer (NSCLC), upper aerodigestive tract cancers, non-colon gastrointestinal cancers, and urothelial carcinoma underwent next-generation sequencing to identify actionable genomic alterations. Eligible patients, based on identified mutations deemed treatable by regorafenib, cabozantinib, or afatinib, were enrolled to receive matched targeted therapies. Outcomes were monitored via Response Evaluation Criteria in Solid Tumors criteria, with dose modifications per National Cancer Institute Common Terminology Criteria for Adverse Events, v4.03 guidelines for adverse events (AEs). RESULTS: One hundred patients with metastatic cancers were enrolled across tumor types. Median treatment durations were 12 weeks (regorafenib), 10.7 weeks (afatinib), and 24.1 weeks (cabozantinib). The overall objective response rate was 7.0%, with 1 complete response and 8 partial responses. The clinical benefit rate, including responses and stable disease >6 months, was 16.0%. Median progression-free survival ranged from 1.9 months for urothelial carcinoma to 3.2 months for NSCLC. Toxicities were common for all medications; for regorafenib, 90.7% of patients had AEs (50% Grade 3/4); for afatinib, 86% of patients had AEs (54% Grade 3/4); for cabozantinib, 100% of patients had AEs (36% Grade 3/4). The most common AEs were diarrhea, fatigue, nausea, decreased appetite, and stomatitis. CONCLUSIONS: Regorafenib, afatinib, and cabozantinib had modest effects when used as molecularly matched targeted therapies in patients with NSCLC, upper aerodigestive tract cancers, non-colon gastrointestinal cancers, and urothelial carcinoma in the second-line setting. Future research could examine more precise matching of therapies to genomic alterations and evaluate combination therapies.

DNA damage response pathway alterations in urothelial carcinoma: a road to precision oncology or a dead-end street?

Urothelial carcinoma ranks among the most common solid tumors and exhibits aggressive behavior, with limited survival in the metastatic setting despite recent therapeutic advances. Currently, 3 first-line systemic treatment options are supported by level IA evidence, yet no validated predictive biomarkers exist to guide selection among them. Alterations in DNA damage response (DDR) pathways occur in a substantial proportion of urothelial tumors and have emerged as potential predictive biomarkers of treatment sensitivity. This review examines the biological basis of DDR pathways and their implications in carcinogenesis, summarizes the frequency and spectrum of DDR gene alterations in urothelial carcinoma, and critically appraises the available evidence linking these alterations to responses to platinum-based chemotherapy, immune checkpoint inhibitors, and PARP inhibitors in both muscle-invasive and metastatic settings. Although retrospective data suggest associations between DDR alterations and improved outcomes with certain therapies, results across studies are heterogeneous, likely reflecting inconsistent definitions of DDR alterations, the variable functional impact of individual mutations, and differences in patient populations. We discuss these limitations and highlight the need for standardized criteria and prospective validation to determine whether DDR pathway alterations can be reliably integrated into clinical decision-making for patients with urothelial carcinoma.

Retrograde intrarenal surgery with flexible and navigable suction access sheaths vs mini-percutaneous nephrolithotomy for large upper urinary tract stones: a systematic review and meta-analysis.

OBJECTIVE: To conduct a meta-analysis comparing the efficacy and perioperative outcomes of contemporary flexible and navigable suction access sheath-assisted retrograde intrarenal surgery (FANS-RIRS) against percutaneous nephrolithotomy (PCNL) for the management of large upper urinary tract stones, as despite technological advances in RIRS such as high-powered lasers and FANS that have substantially enhanced its performance, current guidelines continue to recommend PCNL as first-line treatment for renal stones >2cm. METHODS: MEDLINE, Embase, and the Cochrane Library were searched for studies performing direct comparisons of FANS-RIRS against PCNL in adult patients until September 2025. Primary outcomes included stone-free rates (SFRs) and need for ancillary procedures. Secondary outcomes included operative time, length of postoperative hospitalisation, and postoperative complications. RESULTS: A total of 10 studies (three randomised control trials, seven retrospective cohort studies) comprising 2347 patients were included; preoperative stone sizes were predominantly 2-3 cm. All PCNL procedures in the studies included were performed as mini-PCNL. The SFRs for FANS-RIRS were comparable with mini-PCNL across all stone sizes (odds ratio [OR] 0.90, 95% confidence interval [CI] 0.70-1.17) and stones ≥2 cm (OR 0.80, 95% CI 0.60-1.08), with low heterogeneity. Ancillary procedures rates were similar (OR 1.22, 95% CI 0.61-2.44). FANS-RIRS was associated with significantly fewer overall complications, specifically smaller haemoglobin decline, need for transfusion, and shorter hospital stay. However, mini-PCNL demonstrated shorter operative times for stones ≥2 cm. Urosepsis rates were low and similar between both groups. Limitations include predominance of Asian studies, variability of practice, and inclusion of non-randomised studies. CONCLUSIONS: Contemporary FANS-RIRS achieves SFRs comparable to mini-PCNL even for 2-3 cm stones, while offering superior safety profiles and shorter hospitalisation; this supports FANS-RIRS as a viable primary treatment in selected patients.

Health-system burden of higher-risk myelodysplastic syndromes in England: a literature-based micro-cost analysis.

OBJECTIVES: To quantify the per-patient-per-month (PPPM) cost for each phase of care in higher-risk myelodysplastic syndromes (HR-MDS) and the overall cost of a base-case (illustrative) non-curative management pathway followed by a patient with HR-MDS in England. DESIGN: We conducted a retrospective, literature-based, micro-costing analysis from the National Health Service (NHS) England provider perspective using published sources and publicly available price lists. No individual-patient data were used. Based on literature, a base-case management pathway followed by a patient with HR-MDS was defined as a diagnostic work-up at month 0, 12 cycles of azacitidine (given for 7 days in each 28-day cycle), 5 months of post-hypomethylating agent (HMA) failure supportive care and 1 month of terminal care. SETTING: Healthcare resource utilisation was analysed for adults with HR-MDS who received first-line azacitidine in routine practice if cycle-level or phase-level transfusion and admission rates were reported in the literature. Patients who required allogeneic haematopoietic stem cell transplantation or whose HR-MDS transformed to acute myeloid leukaemia were excluded because the diagnostic and/or therapeutic pathways differ. Unit costs for 2024/2025 were taken from published English national sources and an English trust tariff. RESULTS: PPPM costs were £8721.58 during active azacitidine therapy, £5399.58 after HMA failure and £12 554.58 for hospital-dominant terminal care; a one-off diagnostic work-up with genomics cost £2710 to £2810. The total cost for the base-case management pathway was £146 921 per patient. An alternative pathway excluding genomic testing and assuming hospice-dominant terminal care reduced the total cost to approximately £136 840 to £140 990, depending on whether the lower or upper bound of hospice bed-day costs is applied. CONCLUSIONS: The direct NHS-provider cost burden of this non-curative HR-MDS management pathway is concentrated in azacitidine acquisition and administration during active treatment, transfusions and admissions after HMA failure and setting-dependent costs at the end of life. The total cost for the illustrative management pathway followed by a patient with HR-MDS (£146 921) is of a similar order to the estimate in the National Institute for Health and Care Excellence technology appraisal for azacitidine uprated to £124 848 for 2024/2025. This comparison is provided for context only and should not be interpreted as validation of the present model, given differences in population, model structure, treatment duration and price year. The phase-specific PPPM estimates can inform, subject to local validation and scenario testing, UK budget-impact analyses, service planning and future economic models.

Metformin Adherence and Risk of Polyneuropathy in Type 2 Diabetes Mellitus: An International Matched Cohort Study with Independent Validation.

BACKGROUND: Metformin is a popular first-line glucose-lowering medication for type 2 diabetes mellitus (T2DM). Although metformin reduces the risks of various complications of diabetes, its potential to cause polyneuropathy by depleting vitamin B12 levels is concerning. This study investigated whether the adherence or discontinuation of metformin after adding-on a second-line antiglycemic agent increases the risk of polyneuropathy in patients with T2DM. METHODS: Data from TriNetX were obtained, and patients with T2DM who were receiving second-line antiglycemic agents were divided into metformin-adherent and metformin-nonadherent groups based on prescription claims data. Neuropathy incidence was evaluated using diagnostic claims and nerve conduction examinations. For independent confirmation and external validation of the primary findings, we used data from the National Health Insurance Research Database (NHIRD) of Taiwan. RESULTS: After matching, 58,027 patients were included in each group. Compared with metformin adherent patients, metformin nonadherent patients had a higher risk of polyneuropathy (adjusted hazard ratios [aHR] 1.26; 95% confidence interval [CI] 1.23-1.29; P < 0.001). Risks of diabetic foot ulcer, amputation, neuropathy-related medication use, and bone fracture were also higher among nonadherent patients. Sensitivity analyses confirmed the robustness of findings. In the validation NHIRD cohort (31,384 matched pairs), metformin nonadherence remained associated with increased polyneuropathy risk (aHR 1.25; 95% CI 1.10-1.42; P < 0.001). CONCLUSIONS: Metformin adherence in patients with T2DM who require second-line treatment may reduce the risk of polyneuropathy; vitamin B supplementation may enhance this benefit.

Efficacy of S-1 Monotherapy for Salivary Duct Carcinoma With MYC Amplification.

BACKGROUND/AIM: Salivary duct carcinoma (SDC) is a rare, highly aggressive subtype of salivary gland carcinoma, commonly characterized by overexpression of erb-b2 receptor tyrosine kinase 2 [ERBB2, commonly known as human epidermal growth factor receptor 2 (HER2)] and androgen receptor positivity. Anti-HER2 therapy, platinum-based chemotherapy, and androgen-deprivation therapy (ADT) are commonly provided as standard systemic treatments for advanced SDC; however, effective therapeutic options after failure of these treatments remain limited. The clinical efficacy of S-1 monotherapy in SDC and its predictive biomarkers are not well established. Herein, we present a case in which S-1 monotherapy showed efficacy in a case of SDC after resistance to anti-HER2 therapy, platinum-based chemotherapy, and ADT. CASE REPORT: The patient was a 70-year-old man diagnosed with HER2-positive and androgen receptor-positive SDC of the submandibular gland, who presented with multiple lung metastases. He initially received trastuzumab plus docetaxel as first-line therapy, followed by platinum-based chemotherapy and ADT, but experienced disease progression after each treatment. Comprehensive genomic profiling revealed amplifications of ERBB2 and MYC proto-oncogene bHLH transcription factor (MYC). S-1 monotherapy was started as a late-line therapy. Computed tomography scans 2 months later showed shrinkage of lung and liver metastases, with disease control maintained for more than 5 months. CONCLUSION: S-1 monotherapy may represent a treatment option for patients with advanced SDC refractory to anti-HER2 therapy, platinum-based chemotherapy, and ADT, particularly in cases harboring MYC amplification.

Effectiveness of Wearable Digital Therapeutics in Improving Sleep Outcomes Among Individuals With Insomnia: Systematic Review and Meta-Analysis of Randomized Controlled Trials.

BACKGROUND: Wearable devices are increasingly used for sleep monitoring and as adjunctive treatment. Existing meta-analyses mostly pool composite digital therapies and rarely isolate stand-alone wearables or distinguish between objective and subjective end points. Whether stand-alone wearable interventions improve sleep outcomes in adults with insomnia, and which factors moderate treatment heterogeneity, remains unclear. OBJECTIVE: This study aims to evaluate the effectiveness of wearable digital interventions on sleep outcomes in adults with insomnia versus control strategies and explore moderators of effectiveness, including device-wearing position, intervention duration, and control type, using meta-regression. METHODS: This systematic review and meta-analysis was conducted in accordance with the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta‑Analyses) 2020 statement and the PRISMA-S (Preferred Reporting Items for Systematic Reviews and Meta‑Analyses Literature Search Extension) guideline. Five electronic databases and clinical trial registries were searched from inception to May 18, 2026. Eligible studies were randomized controlled trials (RCTs) evaluating wearable digital interventions in adults with insomnia compared with sham, waitlist, usual care, or active control conditions and had an intervention duration of at least 1 week. Study screening, data extraction, and risk-of-bias assessment were carried out independently by 2 reviewers. Pooled estimates were calculated using a restricted maximum likelihood random-effects model with the Hartung-Knapp-Sidik-Jonkman correction. Heterogeneity was assessed using the I² statistic, and 95% prediction intervals (PIs) were calculated for the primary analyses. The certainty of evidence was rated using the GRADE (Grading of Recommendations, Assessment, Development, and Evaluation) approach. RESULTS: Sixteen RCTs (N=910) were included. Wearable digital interventions were associated with a significant reduction in objective sleep-onset latency (SOL; mean difference [MD] -4.52, 95% CI -8.38 to -0.67, PI -9.52 to 0.47 min) and a significant improvement in subjective sleep efficiency (SE; MD 2.00%, 95% CI 1.90%-2.11%, PI 1.85%-2.15%). Subjective total sleep time (TST) also showed a significant increase (MD 19.11, 95% CI 2.98-35.24, PI -16.20 to 54.43 minutes). Meta-regression showed that control type, intervention duration, and device location did not explain the heterogeneity of the insomnia severity index (ISI) (R²=0). Sensitivity analysis confirmed the robustness of pooled ISI estimates, and an Egger test indicated no small-study effects (P=.07). Certainty of evidence ranged from moderate to high. CONCLUSIONS: Wearable digital interventions provide selective benefits for objective SOL, subjective SE, and subjective TST in adults with insomnia, with no improvement in overall ISI. Despite statistically significant effects on several sleep parameters, wide PIs, substantial heterogeneity, and limited study numbers indicate preliminary, nonconclusive findings. Wearables should be viewed as affordable adjunctive tools requiring further validation, not substitutes for first-line cognitive behavioral therapy for insomnia. Large-scale, long-term RCTs with standardized protocols and patient-level external validation are required to consolidate the evidence base.

Spinal meningiomas: histopathological grading using a benchmark radiomics model with notes on disease control.

OBJECTIVE: Spinal meningiomas (SMs) are common primary spinal tumors for which surgery is considered the first-line treatment when safe and feasible. The ability to extrapolate the tumor grade from preoperative imaging may significantly inform early patient expectation-setting regarding recurrence. Building on radiomics studies in cranial meningiomas, the authors aimed to construct a benchmark radiomics model to preoperatively identify the histological grade of SMs. METHODS: Institutional surgical records from May 2012 to November 2025 were queried for pathology-confirmed meningiomas below the foramen magnum, with preoperative contrast-enhanced imaging available for segmentation. SMs were classified as low-grade (WHO grade 1) and high-grade (WHO grade 2 tumors and grade 1 tumors with atypia). Tumors were manually segmented, and features were extracted using the PyRadiomics software package. An ensemble model of k-nearest neighbors, random forest, and support vector machine classifiers was trained using nested cross-validation on a subset of 10 features to differentiate tumor grades. Clinical data for the cohort were also extracted, and disease control in an adjunctive clinical series was assessed. RESULTS: Seventy-four patients were included in radiomics analysis, with an area under the receiver operating characteristic curve of 0.879 and a mean F1 score of 0.748. The model's top 5 features were all texture features that differed significantly (p < 0.05) across low- and high-grade SMs. These included measures of tumor textural and contrast-enhancement heterogeneity, with overlap with features reported in radiomics models for histological grading of intracranial meningiomas. Fifty-five patients with a median radiographic follow-up of 22.2 (range 1.9-86.4) months remained for clinical analysis after exclusion of patients with less than 1 month of follow-up and syndromic meningiomas. Four recurrences occurred at a median of 20.8 (range 1.8-41.8) months. High-grade tumor pathology did not significantly impact progression-free survival (p = 0.682, log-rank test; Cox regression high vs low grade hazard ratio [HR] 0.62, 95% CI 0.06-6.11, p = 0.685). Subtotal resection was associated with poorer progression-free survival than gross-total resection (p = 0.004, log-rank test; Cox regression subtotal vs gross-total resection HR 10.62, 95% CI 1.46-77.05, p = 0.019). These findings remain contextualized within a relatively limited follow-up window and small recurrence event count, suggesting a need to characterize the interplay between tumor grade and extent of resection as drivers of local disease control in SMs. CONCLUSIONS: A preoperative radiomics model can stratify high-grade SMs using open-source tools applied to single-institution data.

Marked response to dabrafenib plus trametinib in a patient with BRAF V600E-mutant pancreatic hepatoid carcinoma: a case report and systematic analysis of 57 cases.

BACKGROUND: Pancreatic hepatoid carcinoma (PHC) is an extremely rare pancreatic malignancy characterized pathologically by hepatocellular-like differentiation. Some patients may present with elevated serum alpha-fetoprotein (AFP). Owing to the limited number of reported cases, the clinical features, molecular characteristics, and systemic treatment strategies for PHC remain poorly defined. BRAF V600E is an actionable alteration with established therapeutic value in several solid tumors; however, its clinical significance in PHC remains unclear. CASE PRESENTATION: We report the case of a 64-year-old man with advanced PHC who presented with painless jaundice, dark urine, and recent weight loss. Laboratory tests showed marked cholestatic liver injury and significantly elevated AFP. Imaging revealed a pancreatic head-neck mass with portal vein tumor thrombus and regional lymph node metastases, corresponding to cT4N1M1, stage IV disease. Percutaneous transhepatic biliary drainage was first performed to relieve obstructive jaundice. Biopsy of the pancreatic lesion showed poorly differentiated carcinoma. Based on hepatoid morphology, immunophenotype, elevated serum AFP, imaging findings, and exclusion of primary hepatocellular carcinoma, the patient was diagnosed with PHC. Comprehensive genomic profiling identified a BRAF V600E mutation with a variant allele frequency of 31.89%, together with MDM2 and MYC amplification. The molecular profile was characterized by microsatellite stability, low tumor mutational burden, MGMT promoter methylation, and low PD-L1 expression. After two cycles of pembrolizumab-based first-line therapy combined with paclitaxel, S-1, and lenvatinib, AFP continued to increase and imaging showed rapid tumor enlargement, consistent with immune checkpoint inhibitor-related hyperprogressive disease. The treatment was then switched to dabrafenib plus trametinib. AFP declined rapidly and returned to the normal range within approximately two months. Imaging showed marked regression of the pancreatic primary lesion, disappearance of the portal vein tumor thrombus and metastatic lymph nodes, and conversion of peripheral blood minimal residual disease to negative. The best response was partial response. After approximately six months of targeted therapy, occult disease progression emerged. Subsequent addition of cetuximab, replacement of the MEK inhibitor, and dose escalation of targeted therapy did not restore sustained systemic disease control, although local disease remained manageable with subsequent treatment adjustments. Proton radiotherapy was then delivered to the residual pancreatic lesion, followed by CyberKnife radiotherapy for a newly detected 2.3-cm metastasis in the caudate lobe of the liver. As of April 2026, the patient's AFP level remained close to normal at 14 ng/mL, local lesions were well controlled, peripheral blood minimal residual disease had turned positive, and the patient remained in a stable tumor-bearing state. SYSTEMATIC ANALYSIS: We further summarized 57 previously reported cases of PHC. The median age was 54 years, and 66.7% of patients were male. Tumors occurred at different pancreatic sites, including the pancreatic head in 21 cases, body in 8 cases, tail in 13 cases, and multifocal lesions in 15 cases. More than half of the patients had metastatic disease at initial diagnosis. The immunophenotype of PHC was highly heterogeneous. Regarding treatment, 47 patients underwent surgery, 20 received chemotherapy, and 6 received targeted therapy. The 1-year and 3-year overall survival rates were 70.7% and 43.1%, respectively, indicating an overall poor prognosis. CONCLUSION: This case suggests that BRAF V600E may represent a clinically actionable driver alteration in PHC. Dabrafenib plus trametinib induced a rapid and deep response in this patient with advanced BRAF V600E-mutant PHC. Microsatellite stability, low tumor mutational burden, low PD-L1 expression, and MDM2 amplification may be associated with limited benefit from immunotherapy and a risk of hyperprogression. After resistance to targeted therapy, local radiotherapy may serve as an important strategy for controlling oligoresidual and oligometastatic lesions. Together with the literature review, this case supports early comprehensive molecular profiling and individualized multidisciplinary management for advanced PHC.

Fourteen-Day Amoxicillin- or Tetracycline-Containing Bismuth Quadruple Therapy versus 14-Day Metronidazole-Based Triple Therapy as the Treatment for Clarithromycin-Resistant Helicobacter pylori Infection: A Multicenter Randomized Controlled Trial.

BACKGROUND/AIMS: Combination therapy comprising a proton pump inhibitor (PPI), amoxicillin, and metronidazole (PAM) is used to treat clarithromycin-resistant Helicobacter pylori in the Republic of Korea, but eradication rates are decreasing due to an increasing incidence of clarithromycin resistance. We compared PAM, bismuth compounds plus PAM (PAM-B), and the combination of PPI, bismuth compounds, metronidazole, and tetracycline (PBMT) to determine whether PAM-B can achieve an eradication rate higher than that of PAM and comparable to that of PBMT. METHODS: This prospective multicenter study enrolled patients with clarithromycin-resistant H. pylori infections in the Busan and Gyeongsangnam-do of the Republic of Korea between December 2022 and February 2024. RESULTS: In the intention-to-treat (ITT) analysis, the eradication rate was significantly lower in the PAM group (68.2%) than in the PAM-B group (84.8%, p=0.024), whereas the difference from the PBMT group (81.8%) was not significant (p=0.070). The rate remained lowest in the PAM group (75.4%) in the per-protocol (PP) analysis (PAM-B, 96.5%, p=0.001; PBMT, 94.6%, p=0.004). Eradication rates were comparable between the PAM-B and PBMT groups in both the ITT (p=0.640) and PP analyses (p=0.633). Nausea and vomiting were significantly less frequent in the PAM-B group than in the PBMT group (6.8% vs 25.0%; p=0.007). Severe adverse events were rare, and all symptoms resolved after treatment discontinuation. CONCLUSIONS: PAM-B yielded eradication rates higher than those of PAM and comparable to those of PBMT, with no significant increase in the incidence of adverse events, suggesting the potential of PAM-B as a first-line treatment for clarithromycin-resistant H. pylori infection. Further large-scale studies are needed to validate these results. Registered retrospectively with the Clinical Research Information Service (CRIS; KCT0012265).

[Tics and Tourette Syndrome].

Tics disorders and Tourette syndrome (TS) are neurodevelopmental conditions characterized by motor and/or vocal tics with onset in childhood. Their clinical presentation is heterogeneous and fluctuating over time, with exacerbations related to emotional, environmental, and medical factors. Diagnosis is clinical and based on medical history and neurological examination, following DSM-5-TR criteria, with ancillary testing rarely required. The prevalence of TS is estimated at 0.7%, while transient tic disorders affect up to 10% of children. The natural history is generally favorable, with symptom improvement during adolescence, although a subset of patients continues to experience tics into adulthood. Most individuals with TS present psychiatric comorbidities, particularly attention-deficit/hyperactivity disorder and obsessive-compulsive disorder, which significantly impact quality of life and should be prioritized in management decisions. Treatment is recommended only when tics cause functional impairment and follows a stepwise approach including psychoeducation, behavioral interventions, and individualized pharmacological therapy. Comprehensive behavioral intervention for tics is considered first-line treatment when available. Alpha-2 adrenergic agonists and dopamine antagonists are the most commonly used pharmacological options. Neuromodulation therapies are reserved for severe, refractory cases. These recommendations from the Ibero-American Academy of Pediatric Neurology summarize current evidence and provide a practical, updated framework for the diagnosis and management of tic disorders and Tourette syndrome in pediatric patients.
