Efficacy and Safety of Once-Weekly Semaglutide 2.0 mg as an Add-On to Dose-Reduced Insulin Glargine versus Dose-Titrated Insulin Glargine in People With Type 2 Diabetes and Overweight (SUSTAIN OPTIMIZE).

AIMS: Type 2 diabetes (T2D) management with basal insulin can lead to hypoglycaemia and weight gain. SUSTAIN OPTIMIZE compared once-weekly semaglutide 2.0&#x2009;mg as add-on to dose-reduced insulin glargine (Sema+IGlarreduced) versus dose-titrated IGlar (IGlartitrated) on glycated haemoglobin (HbA1c), body weight (BW), daily insulin dose, and participant satisfaction. MATERIALS AND METHODS: SUSTAIN OPTIMIZE was a 40-week, phase 3b, open-label, randomised study. Adults with T2D, overweight (body mass index &#x2265;&#x2009;25&#x2009;kg/m2), and treatment with basal insulin &#x2264;&#x2009;40&#x2009;units/day were randomised 1:1 into Sema+IGlarreduced or IGlartitrated. The primary endpoint was change in HbA1c using a non-inferiority approach. Secondary endpoints assessed superiority of Sema+IGlarreduced versus IGlartitrated in reducing HbA1c, BW, daily insulin dose, and improving Diabetes Treatment Satisfaction Questionnaire change version (DTSQc) scores. RESULTS: Overall, 573 participants were randomised. Sema+IGlarreduced achieved both non-inferiority and superiority versus IGlartitrated in HbA1c reduction (estimated treatment difference [ETD]: -0.74%; 95% confidence interval [CI95]: -0.90, -0.59) and superiority in BW change (ETD: -8.5&#x2009;kg; CI95: -9.5, -7.4), relative daily insulin dose change (ETD: -121.9%; CI95: -143.1, -100.6), and DTSQc scores (ETD: 2.6; CI95: 1.6, 3.5) (p&#x2009;<&#x2009;0.0001 for all endpoints). No new safety concerns were identified. Severe hypoglycaemia was reduced (rate ratio: 0.45; CI95: 0.23, 0.87; p&#x2009;=&#x2009;0.02), while gastrointestinal events were higher for Sema+IGlarreduced (310 vs. 32 events). CONCLUSIONS: Once-weekly subcutaneous semaglutide 2.0&#x2009;mg as add-on to dose-reduced IGlar achieved superior reductions in HbA1c, BW, and daily insulin dose in people with T2D and overweight, while reducing their risk for severe hypoglycaemia compared to dose-titrated IGlar alone.

Single-organ proteomics in Drosophila melanogaster larva.

The combination of genetic accessibility, organ complexity, evolutionary conservation, and cost-efficiency makes Drosophila melanogaster (Dm) a well-known model system for biomedical and fundamental biological research. Proteomic analysis of single organs enables the identification and quantification of proteins expressed in specific organs. This will help to uncover specific biological functions and unique protein profiles that are not detectable in whole-organism analyses. In this study we have isolated single organs form Dm larvae, and we have performed a deep proteomics mapping by following a minimal manipulation preparation procedure. The combined dataset across all organs comprised 9132 identified proteins. As anticipated, principal component analysis (PCA) revealed clear separation between the proteomes of most organs, confirming distinct protein profiles. These findings demonstrate the applicability of the sample preparation strategy for high-resolution proteomic characterization of individual organs in Drosophila. Given the extensive genetic tools available for this model organism, our approach has the potential to open new avenues for proteomic studies in Drosophila melanogaster and any other biological systems where the sample amount is limiting. SIGNIFICANCE STATEMENT: Drosophila melanogaster is a well-known model system for biomedical and fundamental biological research that serves as a valuable in vivo model organism due to its high degree of evolutionary conservation with higher vertebrates, tractable genetics, and logistical efficiency. However, the proteome of Drosophila at single organ level has been elusive to date, due to several factors like low sensitivity of previous generation mass spectrometers and sample preparation procedures, difficult isolation of some organs. In this study we have applied a compilation of advanced methods including minimal sample manipulation together with simple, straightforward and efficient protein extraction and digestion methods. Obtained peptides were minimally handled to be analyzed by applying specific and sensitive nLC methods coupled on-line to state-of-the-art MS/MS system. Altogether, the applied strategy allowed us to get the first single organ study to date for this animal. These datasets represent a significative resource for future genomic, transcriptomic and proteomic studies in Drosophila, as multi-omic integration requires deep proteomics to translate data into functional biochemistry, and serves as a critical bridge and an indispensable standalone resource across the genomic, transcriptomic, and proteomic landscapes.

Vestibular schwannoma associated normal pressure hydrocephalus: clinical features and shunt responsiveness compared with idiopathic NPH.

BACKGROUND: Vestibular schwannoma (VS) is commonly associated with obstructive hydrocephalus due to mass effect; however, a rarer communicating form resembling normal pressure hydrocephalus (NPH) has also been described, possibly related to impaired CSF absorption from elevated CSF protein. We aimed to characterize the clinical and imaging features of VS-associated NPH (VS-NPH) and compare them with those of an idiopathic NPH (iNPH) cohort. METHODS: We retrospectively analyzed 18 patients with VS-NPH identified between 2008 and 2024. For comparison, 41 iNPH patients were drawn from a prospective longitudinal study at our center. Variables included demographics, tumor size, VS treatment modality, CSF parameters, Radscale imaging features, and shunt responsiveness. RESULTS: VS-NPH patients had markedly higher CSF protein levels than patients with iNPH (median 100 vs. 51&#xa0;mg/dL, p&#xa0;<&#xa0;0.001). Radiological features largely overlapped; however, parasagittal sulcal narrowing was more frequent in VS-NPH (61&#xa0;% vs.13&#xa0;%, p&#xa0;=&#xa0;0.002). These differences remained significant in the sensitivity analysis excluding the two patients without gait impairment. VS-NPH patients were younger in the primary analysis (66.8 vs. 72.0&#xa0;years, p&#xa0;=&#xa0;0.03), while exploratory associations between larger tumor size and both earlier NPH symptom onset (r&#xa0;=&#xa0;-0.48, p&#xa0;=&#xa0;0.049) and smaller callosal angle (r&#xa0;=&#xa0;-0.49, p&#xa0;=&#xa0;0.048) attenuated to non-significant trends in the sensitivity analysis. Tumor size was&#xa0;<&#xa0;30&#xa0;mm in 89&#xa0;% of patients. Ventriculoperitoneal shunt (VPS) resulted in clinical improvement in both groups, although response rates were numerically lower in VS-NPH than in iNPH (63&#xa0;% vs.75&#xa0;%). CTT was positive in 9 of 11 VS-NPH patients who underwent testing, although improvement after shunting also occurred in patients with negative CTT results or without prior CTT. CONCLUSIONS: VS-NPH may represent a secondary subtype of NPH with distinct biochemical and subtle imaging features. Elevated CSF protein may contribute to altered CSF dynamics. These findings are exploratory and require confirmation in larger prospective studies.

Resistance versus concurrent training with three assigned protein targets in middle-aged and older women: a randomized 2 &#xd7; 3 factorial trial.

BACKGROUND: Evidence is limited regarding whether assigned protein targets modify responses to resistance training (RT) alone or to the same RT program plus cycling (concurrent training [CT]) in middle-aged and older women. This randomized 2&#x2009;&#xd7;&#x2009;3 factorial trial examined bioelectrical impedance analysis (BIA)-derived skeletal muscle mass (SMM; primary outcome), other body composition outcomes, muscular and functional performance, and cycle-derived estimated VO&#x2082;max. METHODS: In this randomized 2&#x2009;&#xd7;&#x2009;3 factorial trial, 108 women aged 40-77 years were assigned to 12 weeks of supervised RT or CT (identical RT followed by cycling) and protein targets of 0.8, 1.6, or 2.2 g&#xb7;kg-1&#xb7;d-1. Baseline-adjusted ANCOVA tested training&#x2009;&#xd7;&#x2009;protein interactions and marginal training and protein effects. Complete-case analyses included 83 participants. RESULTS: For SMM, no training-condition&#x2009;&#xd7;&#x2009;protein-target interaction (p&#x2009;=&#x2009;0.856), marginal protein-target effect (p&#x2009;=&#x2009;0.726), or marginal training-condition effect (p&#x2009;=&#x2009;0.273) was detected. CT had a lower baseline-adjusted week-12 BFP than RT (adjusted difference, -2.04 percentage points; 95% CI, -2.94 to -1.14; p&#x2009;<&#x2009;0.001). RT had a higher baseline-adjusted week-12 leg-press estimated 1-RM than CT (CT - RT: -6.68 kg; 95% CI, -8.32 to -5.04; p&#x2009;<&#x2009;0.001), whereas CT had a higher baseline-adjusted week-12 cycle-derived estimated VO&#x2082;max (adjusted difference, 4.53 mL&#xb7;kg-1&#xb7;min-1; 95% CI, 3.80 to 5.25; p&#x2009;<&#x2009;0.001). No detectable marginal protein-target effects or training-condition&#x2009;&#xd7;&#x2009;protein-target interactions were observed for the key secondary outcomes. CONCLUSIONS: No detectable differences in SMM or key secondary outcomes were attributable to assigned protein target. Compared with RT, CT favored estimated aerobic fitness and BFP, whereas RT favored leg-press strength. Because CT included additional cycling and greater exercise exposure, these differences cannot be attributed solely to training modality. Null protein findings do not establish equivalence among doses.

Efficacy and Safety of Anti-Obesity Medications for Weight Loss Maintenance in Adults With Overweight or Obesity: A Systematic Review and Meta-Analysis of Randomised Controlled Trials.

AIMS: This systematic review and meta-analysis aimed to evaluate the efficacy and safety of anti-obesity medications (AOMs) for long-term weight maintenance following initial weight loss in adults with overweight or obesity. METHODS: We searched PubMed, Embase, Web of Science and the Cochrane Library from inception to 31 October 2025. Eligible studies were randomised controlled trials (RCTs) comparing AOMs with placebo during the weight-maintenance phase in adults with overweight or obesity after initial weight loss achieved through lifestyle, dietary, surgical or pharmacological interventions. Outcomes included anthropometric indices, cardiometabolic measures, safety endpoints, quality of life and neuropsychiatric adverse events. Weighted mean differences (WMDs) and odds ratios (ORs), each with 95% confidence intervals (CIs), were pooled for continuous and categorical outcomes, respectively, using fixed-effect or random-effects models as appropriate. Risk of bias was assessed using the Cochrane RoB 2 tool, and certainty of evidence was evaluated using the GRADE framework. The protocol was registered with PROSPERO (CRD420261293040). RESULTS: A total of 12 RCTs comprising 4915 participants met the inclusion criteria. Compared with placebo, AOM therapy during the weight-maintenance phase was associated with prevention of weight regain and additional improvements in anthropometric and cardiometabolic outcomes. AOMs led to further reductions in body weight (BW, WMD: -8.68&#x2009;kg, 95% CI: -13.25 to -4.11), waist circumference (WC, WMD: -7.16&#x2009;cm, 95% CI: -10.34 to -3.98) and body mass index (BMI, WMD: -3.58&#x2009;kg/m2, 95% CI: -5.69 to -1.46). Additional benefits were observed for triglycerides, total cholesterol, low-density lipoprotein cholesterol, systolic blood pressure and diastolic blood pressure. Gastrointestinal adverse events were more common with AOMs, whereas serious adverse events were not significantly increased. Neuropsychiatric adverse events were generally comparable between groups, and available quality-of-life measures favoured AOM treatment. CONCLUSIONS: AOM therapy during the weight-maintenance phase can help prevent weight regain, provide further reductions in body weight and improve cardiometabolic risk factors in adults with overweight or obesity. Gastrointestinal adverse events were more common with AOMs, whereas serious adverse events were not significantly increased. Further long-term trials are needed to clarify optimal treatment strategies and safety.

Sodium-glucose cotransporter-2 inhibitors and gastrointestinal neoplasm risk in type 2 diabetes: a systematic review and meta-analysis of randomized controlled trials.

The potential carcinogenic effects of sodium-glucose cotransporter 2 (SGLT2) inhibitors in patients with type 2 diabetes mellitus (T2DM) remain controversial, particularly regarding site-specific gastrointestinal (GI) neoplasms. This systematic review and meta-analysis aimed to determine the relationship between SGLT2 inhibitors and the risk of GI neoplasms in patients with T2DM. We searched PubMed, EMBASE, Cochrane CENTRAL, Scopus, and Web of Science through March 17, 2025, for RCTs in T2DM comparing SGLT2 inhibitors with placebo or active comparators. Two reviewers independently screened studies, extracted data, and assessed the risk of bias. The primary outcome was GI neoplasms reported in publications, supplementary materials, or trial registries, usually as adverse events rather than centrally adjudicated cancer endpoints. Pooled odds ratios (ORs) with 95% confidence intervals (CIs) were calculated in Stata 17.0. In 48 RCTs (n&#x2009;=&#x2009;48,765), SGLT2 inhibitor therapy was not associated with overall GI neoplasm risk (OR&#x2009;=&#x2009;1.10, 95% CI: 0.84-1.44; p&#x2009;=&#x2009;0.46; I&#xb2; = 0%). Site-specific analyses showed no statistically significant association for esophageal (OR&#x2009;=&#x2009;1.12, 95% CI 0.37-3.45), gastric (1.20, 0.65-2.23), hepatic (0.62, 0.31-1.22), pancreatic (0.91, 0.51-1.64), colonic (1.28, 0.78-2.08), colorectal (0.76, 0.27-2.17), and rectal neoplasms (0.98, 0.49-1.97), with all p-values&#x2009;>&#x2009;0.05. Subgroup analyses by agents (e.g., canagliflozin, dapagliflozin, empagliflozin), baseline age, body mass index (BMI), HbA1c, treatment duration, and dose were also non-significant (all p&#x2009;>&#x2009;0.05). Approximately half of the trials had follow-up of one year or less, limiting our ability to evaluate long-term risk. Available RCT evidence does not show a clear increase in GI neoplasm risk with SGLT2 inhibitors in T2DM. However, limited follow-up, low event counts, and non-cancer-specific outcome ascertainment, the findings should be interpreted as reassuring but not definitive evidence of long-term oncologic safety.Systematic review registration: PROSPERO No. CRD42024619019.

Risk factors for bleeding after endoscopic retrograde cholangiopancreatography: a systematic review and meta-analysis.

BACKGROUND AND AIMS: ERCP is associated with adverse events, including bleeding, which occurs in up to 1.3% of cases. This meta-analysis aims to identify and quantify risk factors associated with post-ERCP bleeding. METHODS: A comprehensive literature search of electronic databases was conducted from inception to January 10, 2025. Studies were eligible if they used multivariate analysis to identify predictors of post-ERCP bleeding. Risk factors reported in at least 2 studies were pooled using a random-effects model to calculate odds ratios (ORs) with 95% CIs. A further subgroup analysis was performed, including risk factors for postsphincterotomy bleeding and postendoscopic papillectomy bleeding. RESULTS: Twenty-seven studies (4 prospective and 23 retrospective studies) comprising 149,870 patients were included, of whom 1865 experienced post-ERCP bleeding. Twenty potential risk factors were analyzed. The meta-analysis identified several factors significantly associated with increased odds of post-ERCP bleeding in the pooled adjusted analysis, including male gender (OR, 1.24; 95% CI, 1.05-1.46), anticoagulation therapy (OR, 2.75; 95% CI, 1.66-4.56), cirrhosis (OR, 2.54; 95% CI, 1.76-3.65), hemodialysis (OR, 5.82; 95% CI, 3.32-10.18), coagulopathy (OR, 11.01; 95% CI, 2.50-48.40), endoscopic sphincterotomy (EST) (OR, 3.19; 95% CI, 1.69-6.01), precut sphincterotomy (OR, 2.24; 95% CI, 1.52-3.30), and intraoperative bleeding (OR, 2.57; 95% CI, 1.80-3.66). Several factors in the pooled adjusted analysis were not found to be significantly associated with higher odds of post-ERCP bleeding, including high body mass index (BMI), nonsteroidal anti-inflammatory drug (NSAID) use, antiplatelet therapy, thrombocytopenia, common bile duct stones, cholangitis, endoscopic papillary balloon dilatation, and covered self-expandable metal stent insertion. CONCLUSIONS: This meta-analysis identified that the anticoagulation therapy, cirrhosis, hemodialysis, coagulation disorder, EST, precut sphincterotomy, and male gender are associated with increased odds of post-ERCP bleeding in the pooled adjusted analysis. Conversely, age, high BMI, cholangitis, choledocholithiasis, pancreatic duct stones, needle-knife sphincterotomy, NSAID use, and antiplatelet therapy were not significantly associated with higher odds of post-ERCP bleeding in the pooled adjusted analysis. Incorporating our results into a prediction model may assist in identifying patients at increased risk, optimizing informed consent, and guiding prevention and management strategies for post-ERCP bleeding.

Lateral Femoral Condyle Angle Is an Anatomic Risk Factor for Anterior Cruciate Ligament Primary Injury and Secondary Graft Rerupture.

PURPOSE: To define the lateral femoral condylar angle (LFCA)-a parameter measuring condylar inclination-and assess its predictive capacity for primary and recurrent anterior cruciate ligament (ACL) injuries. METHODS: Patients aged 18 to 50&#x2009;years who underwent primary ACL reconstruction between 2017 and 2022 were screened. Those with graft rerupture were matched 1:1:1 by sex, age, body mass index, and meniscal status to ACL-intact controls and patients without graft failure during a minimum 48-month follow-up. LFCA was measured as the angle between the long axis of the distal femur and the axis of the lateral femoral condyle, alongside 38 established parameters using preoperative 3.0-T magnetic resonance imaging scans. Intergroup differences were assessed with one-way analysis of variance; multivariate regression and receiver operating characteristic analyses identified independent predictors and evaluated predictive performance. RESULTS: The study included 540 patients (180 per group: primary ACL injury, rerupture, controls). One-way analysis of variance revealed a significant gradient in LFCA across controls (81.3&#xb0;, 95% CI: 80.8-81.8&#xb0;), primary injuries (81.9&#xb0;, 95% CI: 81.5-82.3&#xb0;), and reruptures (84.2&#xb0;, 95% CI: 83.7-84.6&#xb0;) (P&#x2009;<&#x2009;.001). In multivariate models adjusted for baseline factors, LFCA independently predicted primary injury (odds ratio [OR]&#x2009;=&#x2009;1.27, 95% CI: 1.13-1.42, P&#x2009;<&#x2009;.001; area under the curve [AUC]&#x2009;=&#x2009;.576) and rerupture (OR&#x2009;=&#x2009;1.46, 95% CI: 1.21-1.76, P&#x2009;<&#x2009;.001; AUC&#x2009;=&#x2009;.704). Combined models incorporating LFCA with tibial slopes, notch angle, and notch height achieved an AUC of .847 for primary injury prediction, whereas models with LFCA, lateral condylar flexion curvature radius, slope asymmetry, and tibial AP distance reached an AUC of .817 for rerupture. LFCA alone with lateral condylar flexion curvature radius yielded an AUC of .777 for rerupture prediction. Sex-stratified analyses confirmed LFCA predicted rerupture in both male patients (OR&#x2009;=&#x2009;1.44, 95% CI: 1.19-1.75) and female patients&#xa0;(OR&#x2009;=&#x2009;1.49, 95% CI: 1.16-1.92), and primary injury in male patients&#xa0;(OR&#x2009;=&#x2009;1.30, 95% CI: 1.15-1.48). CONCLUSIONS: LFCA is an independent predictor of ACL injury, showing particular strength in identifying Asian patients at high risk for graft rerupture. LEVEL OF EVIDENCE: Level III, retrospective case-control study.

Higher Rates of PASS and SCB After Arthroscopic Subspine Decompression Are Associated With a Positive Diagnostic AIIS Injection: A Propensity Score-Matched Cohort Study.

BACKGROUND: Hip arthroscopy effectively treats femoroacetabular impingement syndrome (FAIS), but persistent pain may be related to concomitant extra-articular pathology such as subspine impingement syndrome (SSI). Standard diagnosis of SSI often relies on 3-dimensional computed tomography (3D-CT) morphology (Hetsroni type II/III), although this morphology is common in individuals who are asymptomatic and correlates poorly with symptoms. PURPOSE: To compare minimum 2-year clinical outcomes after arthroscopic subspine decompression in patients with concurrent FAIS and type II/III anterior inferior iliac spine (AIIS) morphology, stratified by diagnostic method: 3D-CT morphology alone versus 3D-CT morphology plus a positive ultrasound-guided diagnostic injection. STUDY DESIGN: Cohort study; Level of evidence, 3. METHODS: This study included patients aged 18 to 55 years with type II/III AIIS morphology who underwent primary hip arthroscopy for FAIS and SSI between January 2021 and November 2023 and had minimum 2-year follow-up. Patients diagnosed by CT morphology alone (CT classification group) were propensity score matched 1:1 to patients with a positive ultrasound-guided AIIS injection (injection group), with 57 patients per group. Matching variables were age, sex, body mass index, lateral center-edge angle, alpha angle, T&#xf6;nnis grade, and Beighton score. All patients underwent arthroscopic subspine decompression. Patient-reported outcomes and rates of achieving the minimal clinically important difference, Patient Acceptable Symptom State (PASS), and substantial clinical benefit (SCB) were compared. RESULTS: Preoperative patient-reported outcome scores were similar between groups (all P > .05). At minimum 2-year follow-up, the injection group had significantly better scores on the modified Harris Hip Score (90.8 vs 84.2), Hip Outcome Score-Activities of Daily Living (88.4 vs 82.4), Hip Outcome Score-Sports Subscale (71.9 vs 64.1), 12-item International Hip Outcome Tool (83.9 vs 76.1), and visual analog scale for pain (1.2 vs 2.0) (all P < .001). Minimal clinically important difference rates were high in both groups, with higher rates in the injection group for modified Harris Hip Score (93% vs 77%; P = .033) and Hip Outcome Score-Activities of Daily Living (91% vs 75%; P = .042). PASS and SCB rates were significantly higher in the injection group across all patient-reported outcome measures (all P < .05). Revision and complication rates were low and did not differ significantly between groups. CONCLUSION: Both groups improved significantly after arthroscopic subspine decompression. However, patients with a positive ultrasound-guided diagnostic AIIS injection achieved higher PASS and SCB rates than those selected by CT morphology alone, suggesting that injection-confirmed SSI may improve patient selection for subspine decompression.

Systemic biomarkers of treatment response to methotrexate in people with painful knee osteoarthritis: A biological substudy of the PROMOTE randomised controlled clinical trial.

OBJECTIVE: Stratification of therapeutic responses may help identify efficacious therapies for osteoarthritis (OA). In the PROMOTE randomised trial, participants with elevated baseline high-sensitivity C-reactive protein (hs-CRP) showed greater pain reduction after methotrexate treatment. We set out to interrogate a broader panel of serum/plasma inflammatory response markers relevant to methotrexate actions as potential biomarkers of therapeutic effect. Our objectives were to: (i) characterize changes in these systemic markers during methotrexate treatment; determine whether (ii) baseline levels or (iii) changes in any marker during treatment were associated with treatment response; and (iv) compare these findings with the more established clinical inflammatory marker, hs-CRP. DESIGN: Plasma/serum samples from participants in PROMOTE's biological substudy were analysed for 35 inflammatory markers at baseline (pre-treatment) and at 6-months (post-treatment), by MesoScale V-plex multiplex assay. Those with paired biological and clinical data at both baseline and 6-months were included in the substudy analysis set. Relationships between markers and overall data structure were assessed by Pearson correlation and Principal Component analysis. Associations between markers (baseline levels or change over time) and change in average knee pain severity in past week (numerical rating scale, NRS) were evaluated by univariable linear regression, adjusting for baseline age, sex, and body mass index. Least Absolute Shrinkage and Selection Operator (LASSO) regression with bootstrap resampling enabled marker selection. Benjamini-Hochberg correction adjusted for multiple testing (Padj). RESULTS: 87 participants with paired blood marker and clinical data were eligible for substudy analysis. 18/35 markers were quantifiable and analysed. Systemic IL-8 and TNF-&#x3b1; levels decreased (Padj=0.015, 0.048 respectively) while IL-15 increased (Padj=0.033) with methotrexate treatment over 6-months. Analysing within this active treatment randomised arm, higher baseline IFN-&#x3b3; was associated with greater reduction in NRS pain change (0.66 [0.01, 1.31], P=0.047), as was decreasing TNF-&#x3b1; over 6-months (2.25 [0.00, 4.5], P=0.049). LASSO identified higher IFN-&#x3b3;, lower plasma IL-15 and IL-16, and younger age as the most important baseline predictors of pain improvement. hs-CRP was highly selected by LASSO for treatment response in both arms. In a secondary univariate treatment arm-by-biomarker interaction analysis, of the 19 markers, only hs-CRP showed consistent effects in adjusted models (at baseline, coeffic. 2.34 [0.53, 4.15], P=0.001; change over 6-months, (0.36 [0.06, 0.66], P=0.018). CONCLUSIONS: Blood measurement of IFN-&#x3b3;, TNF-&#x3b1;, IL-15 and IL-16 as well as hs-CRP could act as potential markers to stratify the treatment response by average knee pain to methotrexate in knee osteoarthritis.

Distal versus proximal radial access for diagnostic cerebral angiography: comparative outcomes and learning curve analysis.

BACKGROUND AND PURPOSE: Distal transradial access (dTRA) is an alternative to proximal transradial access (pTRA) for neuroangiography, but comparative real-world data and evidence on its early learning curve remain limited. We compared procedural performance and access-site complications between dTRA and pTRA and evaluated the early learning curve of dTRA. METHODS: We retrospectively analyzed 470 diagnostic cerebral angiography procedures, representing 421 unique patients, performed via radial access at a single center between January 2025 and February 2026, including 237 dTRA and 233 pTRA procedures. Baseline characteristics, including age, sex, body mass index (BMI) category, aortic arch type, and antiplatelet/anticoagulant use, procedural performance, and clinically assessed access-site events were compared between groups. Radial artery occlusion (RAO) was assessed by postoperative bedside pulse examination and confirmed with Doppler ultrasound when clinical findings were uncertain. Multivariable logistic regression was used to evaluate predictors of RAO, persistent bleeding or repeated compression, hand edema, and a composite access-site event endpoint. Because repeated procedures occurred in a subset of patients and event counts were limited, first-procedure sensitivity analysis and analyses of infrequent outcomes were interpreted cautiously. The dTRA learning process was assessed in the first 100 dTRA cases performed by a single operator using multivariable regression, cumulative sum (CUSUM) analysis, segmented trend analysis, and phase-based comparisons. RESULTS: Baseline characteristics were comparable between groups, including age, male sex, BMI category, aortic arch type, and antiplatelet/anticoagulant use. Compared with pTRA, dTRA was associated with more puncture attempts (3.0 [2.0-4.0] vs 2.0 [1.0-3.0], P&#xa0;<&#xa0;0.001), longer puncture time (2.0 [1.0-5.0] vs 2.0 [1.0-3.0] min, P&#xa0;=&#xa0;0.003), lower first-pass success (19.4% vs 35.2%, P&#xa0;<&#xa0;0.001), and a higher crossover rate (11.4% vs 6.0%, P&#xa0;=&#xa0;0.037). However, dTRA was associated with a lower clinically assessed RAO rate (2.5% vs 7.7%, P&#xa0;=&#xa0;0.011). On multivariable analysis, pTRA was independently associated with higher odds of RAO (OR 3.27, 95% CI 1.26-8.49, P&#xa0;=&#xa0;0.015) and the composite access-site event endpoint (OR 3.12, 95% CI 1.55-6.28, P&#xa0;=&#xa0;0.001). Similar findings were observed in a sensitivity analysis restricted to the first procedure per patient. In the first 100 dTRA cases, cumulative dTRA experience was independently associated with shorter total procedure time (beta&#xa0;=&#xa0;-0.074&#xa0;min/case, P&#xa0;=&#xa0;0.009), while CUSUM and moving-average analyses suggested that the major learning effect occurred within approximately the first 10-15 cases. CONCLUSIONS: In this retrospective single-operator cohort, dTRA was associated with lower clinically assessed RAO than pTRA despite greater access difficulty. The early learning effect was mainly reflected in shorter total procedure time. These findings support the feasibility of dTRA but should be interpreted cautiously given the study's observational design and limited anatomical data.

Acute mild cold exposure with shivering reduces 24 h glucose levels in individuals with type 2 diabetes but not prediabetes.

AIMS/HYPOTHESIS: Repeated cold exposure with shivering has been proposed as a potential strategy to enhance glucose metabolism by increasing energy expenditure and substrate utilisation. However, acute effects/benefits of cold-induced shivering on glucose homeostasis in metabolically compromised individuals are unknown. Here, we aimed to determine whether cold exposure at two different intensities improves 24 h glucose homeostasis in individuals with prediabetes and type 2 diabetes. METHODS: In a randomised crossover trial conducted in the South Limburg/Maastricht region of the Netherlands, men and postmenopausal women with prediabetes (n=12) and stable type 2 diabetes (n=12), aged 40-75 years, body mass index &#x2265;27 and &#x2264;35 kg/m2, non-smoking and sedentary, underwent two whole-body cold exposure sessions using a water-perfused suit. Session order was randomised using an online randomisation tool (randomizer.org); participants were masked to the cold exposure intensity received, but investigators were not. Sessions were designed to elicit ~1.5-fold (mild, 15&#xb0;C) and ~2.5-fold (moderate, 4&#xb0;C) increases in resting metabolic rate (RMR). Continuous glucose monitoring assessed interstitial glucose concentrations over 24 h periods before and after each intervention, with controlled diet and activity. Shivering was confirmed via indirect calorimetry and electromyography. RESULTS: In both study groups and periods, RMR increased significantly vs baseline (p<0.001 for all). In prediabetes, the increase in the final 1 h of cold was 1.53&#xa0;&#xd7;&#xa0;RMR in mild and 1.94&#xa0;&#xd7;&#xa0;RMR in moderate cold. In type 2 diabetes, the increase was 1.57&#xa0;&#xd7;&#xa0;RMR and 2.09&#xa0;&#xd7;&#xa0;RMR in the final 1 h of mild and moderate cold, respectively. In prediabetes, neither mild nor moderate cold exposure altered mean 24 h glucose levels. In contrast, after mild cold exposure the type 2 diabetes group exhibited a significant reduction in mean 24 h glucose levels (-0.6&#xa0;&#xb1;&#xa0;0.5 mmol/l, p=0.003) and fasting glucose (-0.6&#xa0;&#xb1;&#xa0;0.8 mmol/l, p=0.019), as well as an increase in time in normal range (+8.8&#xa0;&#xb1;&#xa0;10.3%, p=0.013) and reduced time in hyperglycaemia (-10.9&#xa0;&#xb1;&#xa0;12.9%, p=0.014). Moderate cold did not significantly affect any of the glucose outcomes in type 2 diabetes. Baseline fasting glucose, age and ALT levels were predictors of the glucose-lowering response, suggesting greater benefits in individuals who have higher baseline glucose levels, are younger and/or have more optimal liver health, i.e. lower ALT. CONCLUSIONS/INTERPRETATION: Acute mild cold exposure with shivering reduced 24 h glucose levels in individuals with type 2 diabetes. No changes were observed in prediabetes. The observed effects appear to depend on baseline metabolic status rather than acute substrate utilisation during cold exposure. These findings support the potential of cold exposure as an adjunct non-pharmacological therapy for type 2 diabetes, although further mechanistic studies and validation in larger cohorts are warranted.

Post-exercise rehydration: a randomized cross-over trial comparing a 100% fruit juice, a glucose-based sports drink, and water.

BACKGROUND: Previous studies indicate that sports drinks may improve rehydration, compared to water, an effect likely achieved by manufacturing sports drinks to contain carbohydrates and sodium. However, there is a growing preference for natural products and a "food first" approach to sports nutrition. Fruit juices naturally contain similar concentrations of carbohydrates to sports drinks, but fruit juices may produce a more stable blood glucose profile. Fruit juices also naturally contain electrolytes, particularly potassium, but their potential as effective rehydration alternatives to sports drinks, which have higher sodium concentrations, is not well understood. This study compared the rehydration efficacy and glucose responses following consumption of a 100% fruit juice (Raw Hydrate&#xae;; FRU), a glucose-based sports drink (SPO), and water (WAT) after exercise-induced hypohydration. Importantly, rehydration beverages were matched for water volume, rather than total volume, to ensure that any potential differences in water balance were not due to unequal water volumes between trials, a limitation affecting previous rehydration research. METHODS: After familiarization, 17 adults (age: 28&#x2009;&#xb1;&#x2009;8&#x2009; years; BMI: 23.8&#x2009;&#xb1;&#x2009;2.9&#x2009;kg/m2) completed three trials in a randomized cross-over design. The participants cycled in the heat (~35&#xb0;C) to induce ~2% body mass loss (BML), then rehydrated over a 1&#x2009;h period in a laboratory (~21&#xb0;C) with a water volume equivalent to 150% of BML from either FRU, SPO, or WAT. This was followed by an additional 4&#x2009;h of seated rest (5&#x2009;h rehydration period), when blood glucose was measured (0, 0.25, 0.5, 0.75, 1, 1.5, and 2&#x2009;h after beverage consumption), and all urine produced was collected. RESULTS: During the 5&#x2009;h rehydration period, there was no effect of trial on total urine volume (FRU: 1266&#x2009;&#xb1;&#x2009;403&#x2009;mL, SPO: 1338&#x2009;&#xb1;&#x2009;361&#x2009;mL, WAT: 1394&#x2009;&#xb1;&#x2009;360&#x2009;mL; P&#x2009;=&#x2009;0.156) or water retention (FRU: 42&#x2009;&#xb1;&#x2009;12%, SPO: 37&#x2009;&#xb1;&#x2009;10%, WAT: 35&#x2009;&#xb1;&#x2009;11%; P&#x2009;=&#x2009;0.059). The blood glucose area under the curve differed by trial (P&#x2009;<&#x2009;0.001), with all beverages significantly different from each other (FRU: 10.12&#x2009;&#xb1;&#x2009;0.72 mmol/L/2h, SPO: 12.48&#x2009;&#xb1;&#x2009;1.34 mmol/L/2h, WAT: 7.90&#x2009;&#xb1;&#x2009;0.47 mmol/L/2h; P&#x2009;<&#x2009;0.003). CONCLUSION: Rehydration efficacy was similar between all beverages, but each elicited a distinct glycemic response. For sports drink consumers seeking a natural alternative or implementing a "food first" nutritional strategy, switching to a 100% fruit juice will not compromise rehydration effectiveness, but may elicit a lower blood glucose response. Although, it should be noted that an additional three participants were withdrawn from the study because of gastrointestinal issues after consuming the 100% fruit juice. This was likely a product of the present study's design, where a large volume of 100% fruit juice (average ~2,300 mL) was consumed in a short period of time (1&#x2009;h). Whilst this is a commonly used study design to robustly assess the rehydration efficacy of different beverages, future studies should distribute fluid intake over a longer duration, in order to improve ecological validity and reduce the risk of gastrointestinal issues.

Pharmacological therapies for the prevention of fractures in men.

RATIONALE: Pharmacological therapies for fracture prevention usually target osteoporosis, a skeletal disorder characterised by compromised bone mass or quality (or both). As most participants in osteoporosis trials are women, a review of pharmacological therapies for fracture prevention in men was warranted. OBJECTIVES: To determine the benefits and harms of bisphosphonates, parathyroid (PTH) or parathyroid-related protein (PTHrP) analogues, denosumab, and romosozumab therapy for the prevention of fractures in men. SEARCH METHODS: We searched CENTRAL, MEDLINE, Embase, and two trial registries (ClinicalTrials.gov and WHO ICTRP) until 14 October 2025, with no restrictions on date or language of publication. ELIGIBILITY CRITERIA: We included randomised controlled trials that compared bisphosphonates, PTH or PTHrP analogues, denosumab, or romosozumab (alone or with calcium or vitamin D, or both) with placebo, other drugs, or non-pharmacological therapies in men aged 50 years or older. Our primary comparison was bisphosphonates versus placebo. OUTCOMES: Critical outcomes were incidence of hip fractures, symptomatic vertebral fractures, other (not hip or vertebral) fractures, disability, participants with adverse events, study withdrawals due to adverse events, and participants with serious adverse events. Our primary time point was the final time point reported in the trials. RISK OF BIAS: We used Cochrane's RoB 2 tool to assess risk of bias. SYNTHESIS METHODS: We used a random-effects model for meta-analysis employing the Mantel-Haenszel approach, and the DerSimonian and Laird method to estimate between-trial variance. We assessed the certainty of evidence using GRADE. INCLUDED STUDIES: Seventeen trials (4132 participants) met our inclusion criteria. The average age of participants ranged from 52 to 73 years. Twelve trials used a placebo comparator versus bisphosphonate (7 trials, 2548 participants), PTH or PTHrP analogues (4 trials, 569 participants), denosumab (1 trial, 240 participants), and romosozumab (1 trial, 244 participants). For the other planned comparisons, a bisphosphonate was compared to vitamin D/vitamin D analogues (2 trials, 434 participants), to calcitonin (1 trial, 32 participants), to PTH or PTHrP analogues (1 trial, 19 participants), or to another bisphosphonate (1 trial, 301 participants), and one trial compared a bisphosphonate plus calcium to calcium tablets alone (46 participants). SYNTHESIS OF RESULTS: Placebo-controlled trials were largely susceptible to bias in selection of the reported result (83%), while most trials without a placebo control were also susceptible to bias arising from the randomisation process (100%) and in measurement of the outcome (80%). We are very uncertain about the effect of bisphosphonates on the incidence of hip fractures, symptomatic vertebral fractures, or other (non-hip non-vertebral) fractures compared to placebo at the final follow-up (up to two years). We downgraded the certainty of evidence once for risk of bias, twice for imprecision (very low event rates), and once for suspected publication bias. The certainty of evidence for incidence of other fractures was further downgraded for indirectness, as it was unclear if hip fractures were also included in the outcome. At up to two years, 2/875 participants (2 per 1000) in the bisphosphonate group reported hip fractures compared with 2/760 (3 per 1000) in the placebo group (risk ratio (RR) 0.73, 95% confidence interval (CI) 0.06 to 8.51; I&#xb2; = 36%; 4 trials, 1635 participants); 5/1021 (4/1000) participants in the bisphosphonate group had a symptomatic vertebral fracture compared to 7/855 (8/1000) participants in the placebo group (RR 0.49, 95% CI 0.14 to 1.74; I&#xb2; = 0%; 5 trials, 1876 participants); 25/1130 participants (16/1000) in the bisphosphonate group reported other (non-hip non-vertebral) fractures compared to 19/913 participants (21/1000) in the placebo group (RR 0.78, 95% CI 0.42 to 1.45; I&#xb2; = 0%; 6 trials, 2043 participants). Bisphosphonates probably do not increase the risk of adverse events: 1024/1374 participants (746/1000) receiving bisphosphonates reported adverse events compared to 826/1174 participants (704/1000) receiving placebo (RR 1.06, 95% CI 0.93 to 1.19; I&#xb2; = 75%; 7 trials, 2548 participants; moderate-certainty evidence) or serious adverse events: 329/1329 participants (272/1000) receiving bisphosphonate reported serious adverse events compared to 323/1128 participants (286/1000) receiving placebo (RR 0.95, 95% CI 0.84 to 1.08; I&#xb2; = 0%; 6 trials, 2457 participants; moderate-certainty evidence). We downgraded the certainty of evidence once due to potential bias for adverse events and serious adverse events. We are very uncertain if bisphosphonates result in more withdrawals due to adverse events: 41/1374 participants (25/1000) in the bisphosphonate group withdrew due to adverse events compared with 43/1174 participants (37/1000) in the placebo group (RR 0.68, 95% CI 0.39 to 1.18; I&#xb2; = 37%; 7 trials, 2548 participants; very low-certainty evidence). We downgraded the certainty of evidence once for risk of bias, once for indirectness, and once for imprecision. No trial reported disability. We are very uncertain about the effects of PTH or PTHrP analogues, denosumab, or romosozumab compared to placebo on fracture outcomes. We are very uncertain about the effects of PTH/PTHrP analogues on total adverse events, withdrawals due to adverse events, and serious adverse events. Denosumab may not increase the risk of adverse events or serious adverse events compared to placebo, while the evidence for withdrawals due to adverse events is very uncertain. Romosozumab probably does not increase the risk of adverse events and may not increase the risk of serious adverse events or result in more withdrawals due to adverse events. AUTHORS' CONCLUSIONS: We are very uncertain about the effects of bisphosphonates compared to placebo on the incidence of hip fractures, symptomatic vertebral fractures, or other (non-hip non-vertebral) fractures in men at up to two years of use. Bisphosphonates probably do not increase the risk of adverse events or serious adverse events, and we are very uncertain if they result in more withdrawals due to adverse events. We downgraded the certainty of evidence for indirectness, imprecision (low event rate), and serious risk of bias in selection of the reported result, as it was unclear if all studies fully reported every fracture. We found similar results for PTH or PTHrP analogues, denosumab, or romosozumab versus placebo. Larger, longer placebo-controlled studies are needed to determine whether pharmacological therapies are beneficial for reducing fractures in men.
