Occlusion site and outcomes in intra-arterial tenecteplase after successful endovascular therapy: a secondary analysis of the ANGEL-TNK trial.

BACKGROUND: Endovascular thrombectomy achieves macroreperfusion in large vessel occlusion (LVO) stroke, but only one-quarter of patients had excellent functional outcome. Adjunct intra-arterial (IA) tenecteplase could further improve the treatment effect, yet its efficacy across internal carotid artery (ICA) versus middle cerebral artery (MCA) M1/M2 occlusion remains unclear. OBJECTIVE: To evaluate whether IA tenecteplase improves 90-day functional outcomes in LVO patients stratified by occlusion site (ICA, MCA M1, MCA M2). METHODS: Prespecified secondary analysis of the ANGEL-TNK trial (multicenter, randomized, open-label, blinded endpoint) in 19 Chinese stroke centers. Participants were enrolled who had anterior circulation LVO, 4.5-24 hours from symptom onset, and CT angiography (CTA)/magnetic resonance angiography (MRA)-proven ICA, M1, or M2 occlusion. INTERVENTION: Randomization (1:1) to IA tenecteplase (0.125 mg/kg) or standard medical management after expanded Thrombolysis in Cerebral Infarction (eTICI) 2b50-3 reperfusion. MAIN OUTCOME MEASURE: The primary outcome was the rate of 90-day modified Rankin Scale (mRS) 0-1. RESULTS: There were 256 patients in the trial, including 71 (27.7%) ICA, 122 (47.6%) MCA M1, and 62 (24.2%) MCA M2. ICA occlusion patients treated with IA tenecteplase had higher rates of 90-day mRS 0-1 (39.4% vs 13.2%; relative risk (RR) 2.99; 95% CI 1.51 to 5.96; p=0.002) and mRS 0-3 (54.5% vs 42.1%; RR 1.30; p=0.048) versus controls, with a significant shift toward better mRS scores (median 3 (IQR 1-4) vs 4 (2-6); odds ratio (OR) 2.26; p<0.001). Post hoc analysis showed higher eTICI progression in ICA patients (51.5%) versus MCA M1 (37.9%) and M2 (25.7%). IA tenecteplase had a lower any intracranial hemorrhage within 48 hours in ICA patients (15.2% vs 39.5%; RR 0.38; p<0.001) compared with standard medical management. No significant benefits were observed in the MCA M1/M2 subgroups, and interaction effects were significant between ICA and MCA segments for functional outcomes and safety. CONCLUSIONS AND RELEVANCE: IA tenecteplase had a better functional outcome and lower hemorrhage risk in ICA occlusion compared with standard medical management but not in MCA M1/M2. Occlusion site is a critical determinant of response to IA tenecteplase. A pooled analysis of IA tenecteplase stratified by occlusion site strata is warranted.

Ginkgo biloba versus desmopressin in treatment of children with monosymptomatic nocturnal enuresis: A randomized controlled trial.

OBJECTIVE: To evaluate the efficacy and safety of Ginkgo biloba extract (GBE) compared with Desmopressin and their combination in children with monosymptomatic nocturnal enuresis (MNE). METHODS: In this double-blind, randomized, placebo-controlled trial, 398 children aged 5-14 years with MNE were assigned to four groups: placebo, GBE (60 mg daily), Desmopressin (0.2 mg daily), or GBE plus Desmopressin for 3 months. Primary outcomes included the number of wet nights per week. Secondary outcomes assessed sleep quality using the Sleep Disturbance Scale for Children (SDSC), arousal by the Disorders of Arousal (DA) score, and quality-of-life using the Pediatric Incontinence Questionnaire (PinQ). RESULTS: After 3 months, the combination group demonstrated the greatest improvement in wet nights (median 0 [IQR 0-2]) compared to GBE (6 [0.5-6.5]) and Desmopressin (2 [0-6]) (p < 0.001). Full response rates (≥90% reduction in wet nights) were highest with combination therapy (88.3%), followed by Desmopressin (46.5%), GBE (24.8%), and placebo (9.5%) (p < 0.001). GBE-containing groups showed significantly increased DA and SDSC scores, indicating enhanced arousal and lighter sleep. Quality-of-life (PinQ) score decreased in all treatment groups denoting improvement, with the best outcomes observed in the combination arm. Adverse effects were mild and comparable across groups, and serum sodium levels remained stable. CONCLUSION: GBE is a safe and effective novel therapy for MNE, improving sleep arousal and symptom control. Its combination with Desmopressin offers superior efficacy, better quality of life, and lower relapse rates than either agent alone.

Efficacy and Safety of Celecoxib Combined With Jintiange Capsules for the Treatment of Knee Osteoarthritis: A Randomized, Double-Blind, Placebo-Controlled Clinical Trial.

BACKGROUND Knee osteoarthritis (KOA) poses a substantial global health burden, and conventional nonsteroidal anti-inflammatory drug (NSAID) therapy with celecoxib is hindered by adverse effects. This study evaluated the efficacy and safety of combining celecoxib with Jintiange capsules, a synthetic tiger bone formulation used in traditional Chinese medicine (TCM), to manage symptomatic KOA. MATERIAL AND METHODS This 12-week, randomized, double-blind, placebo-controlled trial enrolled 120 patients with KOA (age 40 years; visual analog scale [VAS] score 4-7). Participants received celecoxib (200 mg/day tapered to 100 mg/day) combined with either Jintiange capsules (3.6 g/day) or placebo. The primary outcome was the change in the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) total score. Secondary outcomes included WOMAC subscale scores (pain, function, and stiffness), VAS scores, and adverse drug reaction reports. RESULTS The experimental group demonstrated a 23.5-point (37.8%) reduction in WOMAC total score from baseline (P<0.001); the control group showed a 13.2-point (21.6%) reduction (P<0.001). The experimental group achieved 51.6% improvement in the WOMAC pain subscale (P<0.001), whereas the control group showed 33.3% improvement (P<0.001). Relative to the control group, the experimental group demonstrated a greater reduction in VAS score (P<0.001). Combined TCM-NSAID therapy produced significantly greater pain relief and functional improvement than NSAID monotherapy. CONCLUSIONS Celecoxib combined with Jintiange capsules provided clinically meaningful improvements in pain relief and functional outcomes relative to celecoxib monotherapy in patients with KOA. These findings support integration of TCM with conventional pharmacotherapy for osteoarthritis management.

Efficacy and Safety of Rivaroxaban in Patients with Peripheral Artery Disease: A GRADE-assessed Systematic Review and Meta-Analysis.

BACKGROUND: Peripheral artery disease (PAD) is a common atherosclerotic disorder characterized by progressive arterial narrowing in the limbs. This study aims to determine the efficacy and safety of rivaroxaban, focusing on major cardiovascular events, limb outcomes, and bleeding risks. METHODS: PubMed, Cochrane, and EMBASE were searched for randomized controlled trials (RCTs) and nonrandomized comparative studies that compared rivaroxaban, either alone or in combination with aspirin, to placebo or standard care such as antiplatelet therapy. Risk ratios and hazard ratios with 95% confidence intervals were pooled using R v4.5.1 with an appropriate random-effects model applied. Subgroup analyses were performed according to rivaroxaban plus aspirin versus rivaroxaban alone. RESULTS: A total of 39,991 participants across 6 studies were included. Compared with control, use of rivaroxaban was linked to a significant reduction in composite efficacy outcomes (relative risk [RR] = 0.84, 95% confidence interval [CI] 0.78-0.91, P < 0.001), risk of acute limb ischemia (RR = 0.65, 95% CI 0.55-0.78, P < 0.001), and thromboembolism (RR = 0.60, 95% CI 0.38-0.97, P = 0.037). Although rivaroxaban plus aspirin failed to show a significant reduction in the risk of amputation, rivaroxaban alone reported a significant risk reduction (RR = 0.50, 95% CI 0.30-0.85, P = 0.003). However, its use was associated with a significantly higher risk of major bleeding (hazard ratio [HR] = 1.54, 95% CI 1.38-1.72, P < 0.001) and International Society on Thrombosis and Hemostasis-defined bleeding (RR = 1.45, 95% CI 1.19-1.76, P < 0.001). No significant differences were observed for stroke, myocardial infarction, major adverse limb events, fatal bleeding, mortality, or cardiovascular mortality. CONCLUSION: Rivaroxaban-based therapy reduced the trial-defined composite efficacy outcome, acute limb ischemia, and thromboembolism in patients with PAD, but increased the risk of major bleeding. These findings support individualized use of rivaroxaban-based therapy in carefully selected patients, balancing ischemic and limb-protective benefits against bleeding risk.

Chronic postsurgical pain: risk assessment and mitigation.

PURPOSE OF THE REVIEW: Chronic postsurgical pain (CPSP) and persistent postoperative opioid use (PPOU) are two of the most common complications of a number of surgical interventions, which can cause significant personal and economic negative consequences. This review outlines known and potential risk factors for CPSP and PPOU and approaches to reduce these risk factors. RECENT FINDINGS: Modifiable risk factors for developing CPSP include psychological distress, preoperative pain intensity, and perioperative opioid exposure. Although less studied, psychological comorbidities are also risk factors for PPOU. Evidence-based mitigation strategies include psychological interventions and perioperative opioid sparing. SUMMARY: A number of perioperative risk factors for developing CPSP and PPOU have been identified, and anesthesiologists should be cognizant of these risk factors and potential risk mitigation strategies. Additional prospective studies are needed to further develop easily adoptable, evidence-based interventions to reduce the incidence of CPSP and PPOU.

Integrated genomic and biochemical diagnosis of a novel homozygous start-loss variant in AKR1D1 associated with neonatal cholestasis.

INTRODUCTION: Congenital bile acid synthesis defects are rare autosomal recessive disorders that typically present in early infancy with cholestasis, progressive liver dysfunction, and, in severe cases, acute liver failure. These conditions may mimic other metabolic diseases detected in newborn screening, complicating early diagnosis. The AKR1D1 gene encodes Δ4-3-oxosteroid 5β-reductase, a key enzyme in primary bile acid synthesis, and pathogenic variants cause bile acid synthesis defect type 2 (OMIM #235555). CASE DESCRIPTION: We report a 3-month-old male infant with severe neonatal cholestasis and a history of elevated tyrosine levels in newborn screening. Pregnancy was high risk and unmonitored, with birth outside a hospital. Parental consanguinity was first-degree. Early metabolic evaluation showed transient normalization of tyrosine levels, but subsequent analyses revealed recurrent hyper-tyrosinemia. Urinary organic acids showed increased 4-hydroxyphenyl metabolites, with absent succinylacetone, excluding tyrosinemia type I. Progressive cholestasis developed, accompanied by coagulopathy, hyperbilirubinemia, hyperammonemia, and markedly elevated alpha-fetoprotein. Imaging revealed no structural liver abnormalities. Clinical exome sequencing identified a novel homozygous start-loss variant in AKR1D1, likely abolishing functional enzyme production. Metabolic studies confirmed increased urinary excretion of 3-oxocholenoic acids consistent with abnormal bile acid synthesis and supporting a diagnosis of bile acid synthesis defect type 2. Oral cholic acid therapy led to stabilization and improvement in clinical and biochemical parameters. DISCUSSION/CONCLUSION: This case illustrates the diagnostic complexity of neonatal cholestasis, particularly when initial metabolic findings suggest alternative etiologies. It highlights the importance of newborn screening as a tool for broader diagnostic suspicion and the critical role of early molecular diagnosis and multidisciplinary care. Timely recognition and targeted therapy can improve outcomes, prevent liver transplantation, and enable accurate genetic counseling, especially in consanguineous families.

The Natural History of Residual and Recurrent Disease in Advanced Juvenile Nasopharyngeal Angiofibroma: A Systematic Review.

OBJECTIVE: This systematic review explores the natural history of residual and recurrent juvenile nasopharyngeal angiofibromas (JNAs) to inform clinical decision-making. DATA SOURCES: PubMed, Embase, Scopus, and Web of Science. REVIEW METHODS: A systematic literature review was conducted according to PRISMA guidelines across PubMed, Embase, Scopus, and Web of Science from inception to February 20, 2025 and was re-run on September 21, 2025. Studies included patients with advanced JNA and documented follow-up of residual or recurrent disease. Descriptive statistics, chi-squared analysis, and analysis of variance were used to evaluate treatment outcomes across different modalities including surgery, radiotherapy, gamma knife surgery, and medical therapies. RESULTS: Twenty-one studies encompassing 131 male patients (mean age 16.3 years) were included. Residual or recurrent disease demonstrated complete involution in 41%, stable disease in 29%, and reduction in size in 25% of cases. Only 2% of patients had progressive disease. A statistically significant association was observed between treatment modality and outcome (p = 0.015), with radiotherapy, either alone, or as part of a multimodal approach, showing the highest rates of spontaneous involution. CONCLUSION: Residual and recurrent JNAs often remain stable or regress without further intervention. Close surveillance with imaging is a safe and effective strategy for asymptomatic patients, minimizing the risks of additional treatment in a young patient population with disease near critical anatomical structures.

Efficacy and Safety Profile of a Triple Single-Pill Combination of Valsartan/Amlodipine/Chlorthalidone in Patients with Uncontrolled Hypertension.

PURPOSE: This randomized, double-blind, multicenter Phase III study evaluated the efficacy and safety profile of a single-pill triple combination of valsartan/amlodipine/chlorthalidone (KDF1901, Valdipine Plus) compared with a dual combination of valsartan/amlodipine (KDF1901-R) in patients with essential hypertension. METHODS: Patients (n = 294) with inadequately controlled hypertension after a 4-week run-in phase with valsartan/amlodipine (80/5 mg) were randomized to receive KDF1901 (valsartan/amlodipine/chlorthalidone 160/10/25 mg, n = 147) or KDF1901-R (valsartan/amlodipine 160/10 mg, n = 147) for 8 weeks. The primary efficacy endpoint was the change in mean sitting systolic blood pressure (MSSBP) from baseline to week 8. Secondary endpoints included changes in mean sitting diastolic blood pressure (MSDBP), BP normalization rates, and response rates. Safety profile outcomes assessed treatment-emergent adverse events (TEAEs), laboratory parameters, and serious adverse events. FINDINGS: At week 8, the KDF1901 group exhibited a significantly greater reduction in MSSBP (-22.8 ± 1.0 mmHg) compared with the dual therapy group (-16.7 ± 1.0 mmHg, P < 0.0001). Similarly, the mean MSDBP reduction was significantly greater with KDF1901 (P = 0.0006). BP normalization rates (75.9% vs 54.5%, P < .0001) and response rates (73.8% vs 51.7%, P < 0.0001) were significantly higher in the triple combination group. Overall, the incidence of TEAEs was similar between groups (24.7% vs 21.5%, P = 0.5783), with mild cases of dizziness were most commonly reported. Exploratory ad hoc analyses showed statistically greater changes in sodium, potassium, and uric acid levels with triple therapy, but clinically meaningful extreme electrolyte abnormalities were rare in both groups, and the overall laboratory profile remained acceptable. IMPLICATIONS: This trial reported that the single-pill triple combination KDF1901 significantly improved BP control compared with dual therapy without compromising tolerability. GOV IDENTIFIER: NCT07116863.

Molecular evaluation of residual disease following neoadjuvant chemotherapy in triple-negative breast cancer CALGB 40603 (Alliance).

BACKGROUNDDespite therapeutic advances in early-stage triple-negative breast cancer (TNBC), residual disease (RD) following neoadjuvant therapy remains a key predictor of a worse prognosis and obstacle to improving patient outcomes.METHODSTo better characterize RD and identify survival-associated features, we performed comprehensive transcriptomic profiling of 340 pretreatment stage II/III TNBCs and 70 matched posttreatment RD samples from the randomized CALGB 40603 (Alliance) phase II clinical trial. To explore preclinical treatment strategies for RD, patient-derived xenograft (PDX) mouse models mimicking RD were treated with antibody-drug conjugates (ADCs).RESULTSOur study shows prognostic genomic features measured pretreatment may differ from prognostic features measured posttreatment from RD specimens. Patients with a genomic PAM50 subtype of basal-like in RD specimens had a poor survival outcome, and their matching pretreatment tumors were characterized by elevated chromosomal amplifications of oncogenic drivers and significantly reduced B and T cell expression features. Paired analyses of basal-like RD and matched pretreatment tumors revealed further lymphocyte depletion in RD, along with lower expression of MHC class I and interferon signaling, indicating an immune-cold RD microenvironment. Treatment of a basal-like and conventional chemotherapy-resistant PDX model, resembling basal-like RD, with sacituzumab govitecan or trastuzumab deruxtecan produced a marked antitumor response.CONCLUSIONRD biology differs from pretreatment tumors, with basal-like subtype RD following neoadjuvant chemotherapy being immune cold and associated with poor survival. Preclinical modeling suggests this high-risk group may benefit from adjuvant ADC therapy.TRIAL REGISTRATIONClinicalTrials.gov NCT00861705.FUNDINGNIH NCI U10CA180821 (Alliance for Clinical Trials in Oncology), NCI U24CA176171 (Alliance for Clinical Trials in Oncology), NCI UG1CA233373 (Alliance for Clinical Trials in Oncology), NCI Breast SPORE program P50-CA058223; Susan G.

Effects of exercise on aerobic capacity in people with prehypertension or hypertension: a systematic review and meta-analysis of randomized controlled trials.

This study aimed to quantify the effects of exercise on aerobic capacity in people with prehypertension or hypertension and to identify exercise prescription parameters that optimize improvements. A comprehensive search was conducted in PubMed, Web of Science, Embase, Cochrane Library, and Scopus from inception to 24 October 2025. Data were pooled using standardized mean differences (SMDs) with 95% confidence intervals (CI). Fifteen studies met the inclusion criteria. Exercise significantly improved aerobic capacity in people with prehypertension or hypertension (SMD = 0.88; 95% CI: 0.61-1.15; P  < 0.00001), with multicomponent training demonstrating superior efficacy. Exploratory subgroup analyses suggest that longer programs (≥12 weeks), lower frequency (<3 sessions/week), 60-min sessions or longer, total weekly exercise less than 180 min, and professional supervision may be associated with better outcomes.

Transcranial Photobiomodulation Variables Assessment Battery: Development and Validation.

Transcranial photobiomodulation (tPBM) response variability is partly driven by biophysical characteristics such as skin tone and hair properties that attenuate photon penetration, and by lifestyle factors including sleep quality, alcohol use, and nicotine consumption that disrupt the mitochondrial and vascular pathways on which tPBM acts. To date, no validated self-report tool exists to capture these moderators systematically. To address this gap, the tPBM Variables Assessment Battery was developed and psychometrically evaluated. It integrates adapted versions of established measures (Brief Pittsburgh Sleep Quality Index, E-cigarette Dependence Scale, Hair Scale Assessment PRO, Monk Skin Tone Scale, and Heaviness of Smoking Index), validated wellbeing evaluators (Ryff's Psychological Wellbeing), and custom measures (Hairstyle Classification, Hair Color Classification). Face and content validity met recommended expert thresholds, internal consistency was acceptable across adapted subscales, and criterion validity analyses confirmed meaningful associations between the lifestyle components and PROMIS-10 global health outcomes. The battery is low-burden, digitally deployable, and psychometrically defensible, offering a practical tool for characterizing the variables most likely to moderate tPBM response in home-use studies.

Examining Behavioral Interventions for Infancy and Early Toddlerhood: A Systematic Review of Intervention Effects, Parameters, and Participants.

Rapid advancement is paving the way to identify children who would likely benefit from early intervention during the first years of life, prior to the onset of significant delays in development. With the widely acknowledged benefits of early intervention, key questions arise: Does behavioral intervention targeted to infancy and early toddlerhood improve developmental outcomes? What procedures might be used, and under what circumstances? Who do these interventions work for? The current review comprehensively examined the literature on behavioral interventions based in operant learning, focused on key developmental areas with children in the first two years of life. We located and synthesized 69 studies with unique participant cohorts that included 1735 children. The search revealed many studies focused on the first year of life, of which a large proportion investigated approaches to increase communication. We provide implications, limitations, and future directions on how behavioral interventions for infants and young toddlers can inform current practice and future intervention research this population.

Outcomes of stereotactic radiosurgery for spine multiple myeloma-a systematic review.

Spinal involvement in multiple myeloma (MM) commonly results in pain, vertebral instability, epidural spinal cord compression, and neurological deficits. Although conventional external beam radiation therapy (EBRT) remains the standard radiation modality because of the radiosensitive nature of MM, stereotactic radiosurgery (SRS) has emerged as a highly conformal treatment option capable of delivering focal high-dose radiation while sparing adjacent spinal cord structures and uninvolved bone marrow. This systematic review evaluated the clinical outcomes and safety profile of SRS for spinal MM. A systematic review of the literature was performed to identify studies evaluating SRS for spinal MM. Extracted variables included patient demographics, tumor characteristics, treatment parameters, radiographic outcomes, pain response, neurological outcomes, local control, overall survival, and adverse events. Three retrospective studies comprising 133 patients and 181 treated spinal lesions met the inclusion criteria. Median patient age ranged from 59 to 65 years, with a slight male predominance across studies. Thoracic spine lesions represented the most treated region (55.5-67.7%). Median prescribed SRS dose was 14-16 Gy, predominantly delivered in a single fraction. Median follow-up ranged from 11.2 to 27.8 months. Local control rates ranged from 89.4 to 100%, with 6- and 12-month local control rates of 94% and 91%, respectively, in one study. Pain improvement was reported in 41-88% of treated patients/sites, with a median time to pain relief of 1.6 months in one cohort. Neurological improvement occurred in 56-71.4% of patients with preexisting deficits. Reported adverse events included vertebral compression fractures, fracture progression, pain flare, and tracheoesophageal fistula. De novo vertebral fractures ranged from 3.6 to 7%, while fracture progression ranged from 14 to 18%. SRS appears to provide excellent local control and meaningful pain and neurological improvement in patients with spinal MM, with acceptable toxicity profiles. The highly conformal nature of SRS may preserve uninvolved bone marrow and facilitate continuation of systemic therapy. However, the current evidence is limited to small retrospective studies with heterogeneous reporting, and further prospective comparative studies are needed to better define the role of SRS relative to conventional EBRT in spinal MM.

The present and future of nonviral delivery-based genome editing for hereditary hearing loss.

PURPOSE OF REVIEW: This review summarizes nonviral genome-editing delivery platforms for hereditary hearing loss, focusing on lipid nanoparticles (LNPs) and engineered virus-like particles (eVLPs), and discusses their advantages over adeno-associated virus-based delivery, as well as the barriers to clinical translation. RECENT FINDINGS: Recent advances have established LNPs as a clinically advanced nonviral platform, although challenges related to inner ear biodistribution, cell type specificity, endosomal escape, and immunogenicity remain to be addressed. In parallel, eVLPs have undergone substantial technical evolution, progressing from early low efficiency systems to advanced base editor- and prime editor-eVLP architectures that enhance cargo loading and editing efficiency. Extracellular vesicle-based genome editing has also emerged as an additional platform, although issues related to reproducibility, loading efficiency, and scalability remain major hurdles. SUMMARY: Nonviral genome editing platforms expand the therapeutic toolkit for hereditary hearing loss by enabling transient delivery of genome editors with potential safety advantages. Future efforts should focus on characterizing biodistribution and immunogenicity, refining cell type-specific tropism, and establishing scalable manufacturing processes to enable successful clinical translation.

Overcoming Immunological Barriers in MSC-Derived Insulin-Producing Cells through CRISPR-Based Hypoimmunogenic Engineering and Translational Perspectives for Type 1 Diabetes.

Mesenchymal stromal cell (MSC)-derived insulin-producing cells (IPCs) represent an emerging strategy for β-cell replacement in type 1 diabetes mellitus (T1DM) owing to their differentiation potential, intrinsic immunomodulatory properties, and lower tumorigenic risk compared with pluripotent stem cell-derived platforms. However, accumulating evidence indicates that differentiation-associated immunogenicity, context-dependent immune recognition, and recurrent autoimmune responses may substantially limit long-term graft survival and therapeutic durability following transplantation. This review critically examines the immunological barriers associated with MSC-derived IPCs, including altered MHC expression, susceptibility to alloimmune and autoimmune-mediated rejection, and potential reactivation of autoreactive immune memory. We discuss the application of CRISPR-based hypoimmunogenic engineering strategies targeting antigen presentation pathways, NK-cell activation, and immune checkpoint modulation to generate more immune-evasive MSC-derived IPCs while preserving β-cell functionality. By integrating insights from T1DM immunopathogenesis, MSC biology, genome editing, and translational immunology, we propose a framework linking immune engineering with controlled differentiation, functional maturation, and long-term safety evaluation. In parallel, we comparatively position MSC-derived IPCs alongside clinically advancing iPSC-derived β-cell platforms to highlight their distinct translational niche, including potential advantages related to safety, immunomodulatory capacity, manufacturing accessibility, and scalability, while acknowledging the superior functional maturity and clinical progression currently demonstrated by iPSC-derived systems. Finally, we discuss key translational challenges, including genomic stability, immune-evasion durability, GMP-compliant manufacturing, and the need for rigorous functional and immunological benchmarking prior to clinical application of hypoimmunogenic MSC-derived IPC therapies in T1DM.

A system-level metastable model of cancer evolution: integrating replication stress, cell cycle deregulation and chromosomal instability.

INTRODUCTION: Cancer cell proliferation occurs within the context of persistent genomic instability. In this review, we propose the RS-CCD-CIN axis as a systems-level framework in which replication stress (RS), cell cycle deregulation (CCD) and chromosomal instability (CIN) form an interdependent triad that shapes tumour evolution. This axis represents a constrained metastable state in which genomic instability is tolerated and buffered. The objective of this review is to synthesize the current understanding of how the RS-CCD-CIN axis contributes to tumour heterogeneity, adaptability and therapy response. DISCUSSION: Evidence indicates that RS, CCD and CIN operate as a dynamic, interconnected network rather than as independent processes. Replication stress induces DNA damage and mutagenesis, while partial checkpoint disruption permits cells with unresolved lesions to proliferate. Chromosomal instability generates both structural and numerical alterations, contributing to intratumoural heterogeneity. Together, these processes facilitate adaptation to environmental and therapeutic pressures. Extrachromosomal DNA, micronuclei formation and cytosolic DNA signalling, including the cGAS-STING pathway, connect genomic instability to adaptive responses and immune modulation. Single-cell and spatial profiling reveal temporal and spatial variability in RS, CCD and CIN states, highlighting the limitations of static biomarkers. Therapeutically, targeting individual components often yields limited durability, whereas approaches that simultaneously perturb multiple aspects of the RS-CCD-CIN axis may improve clinical outcomes. CONCLUSIONS: This review highlights the RS-CCD-CIN axis as a fragile and metastable architecture that supports cancer evolution, while also being susceptible to collapse. A deeper understanding of this interconnected framework may inform the development of therapeutic strategies and enhance the management of resistance.

Effect of an oral complementary medicine combination for symptomatic knee osteoarthritis: A double-blind, randomized, placebo-controlled trial.

OBJECTIVE: Many individuals use complementary medicine therapies for osteoarthritis, despite limited scientific supporting evidence. These therapies have demonstrated anti-inflammatory, antioxidative, and chondroprotective effects via different molecular pathways, suggesting potential therapeutic benefits. This trial aimed to evaluate the efficacy and safety of a novel oral complementary medicine combination in adults with symptomatic knee osteoarthritis at 12 weeks. DESIGN: The 12-week, double-blind, randomized, placebo-controlled ATLAS trial was conducted in Australia from July 2024 to April 2025 (ACTRN12623000380695). Eligible participants were aged ≥40 years with symptomatic knee osteoarthritis and radiographic Kellgren-Lawrence grade ≥2. Participants were randomized 1:1 to receive the complementary medicine combination, comprising a total daily dose of Boswellia serrata extract 250 mg, pine bark extract 100 mg, methylsulfonylmethane 1500 mg, curcumin 500 mg, and piperine 5 mg, or placebo. The primary outcome was the 12-week change in knee pain (0-100 mm visual analogue scale (VAS)). A 95% confidence interval excluding differences >18 mm between groups was interpreted as the absence of a clinically meaningful difference. Harms were monitored weekly. RESULTS: Eighty-four participants were recruited (mean [SD], age 63.7 [8.0] years, BMI 29.0 [5.5] kg/m2), and 57% were female. At 12-weeks, both groups (intention-to-treat population: complementary medicine, n=42; placebo, n=41) showed a decrease in VAS pain (least squares means: complementary medicine 20.1 mm vs placebo 20.3 mm), however with no difference between groups: 0.16 mm (95% CI -6.81 to 7.12). The safety profile of experiencing any AE was similar between groups (risk difference, -3.4% [95% CI -24.8-17.9%]); and most adverse events were mild or moderate. Four participants experienced serious adverse events, unrelated to the treatment. CONCLUSIONS: The complementary medicine combination was not superior to placebo for improving pain over 12 weeks, and the evidence does not support the use of this combination to treat people with symptomatic knee osteoarthritis.

Near and distance vergence facility provides complementary clinical information in concussion-related convergence insufficiency.

PURPOSE: To compare near and distance vergence facility testing in adolescents and young adults with concussion-related convergence insufficiency and evaluate changes following office-based vergence/accommodative therapy (OBVAM). METHODS: This secondary analysis of the CONCUSS randomized clinical trial evaluated vergence facility at near (40 cm) and distance (4 m) using a 12Δ base out/3Δ base in prism flipper. Participants aged 11-25 years with concussion-related convergence insufficiency were randomized to immediate or 6 weeks delayed OBVAM. Vergence facility was assessed at baseline, outcome time 1 assessment (after 12 therapy sessions for the immediate group and 6 weeks of watchful waiting for the delayed group), and outcome time 2 assessment (after both groups completed 16 therapy sessions). Agreement between near and distance vergence facility classifications was evaluated, and treatment-related changes were compared between groups. RESULTS: Of the 106 enrolled participants, 102 completed all study visits. At baseline, the near and distance vergence facility classifications demonstrated substantial discordance. Among 101 participants with both measures available, 49 demonstrated reduced distance vergence facility despite normal near vergence facility, whereas only two showed the opposite pattern (Cohen's κ = 0.12; p < 0.0001). Vergence facility improved following therapy in both treatment groups, with larger early improvements in the immediate-treatment group. CONCLUSIONS: Near and distance vergence facility testing provided complementary rather than interchangeable clinical information in adolescents and young adults with concussion-related convergence insufficiency. Both measures improved following vergence/accommodative therapy, supporting consideration of both testing distances in clinical assessment.
