Effects of passive blood flow restriction on muscle function following exercise-induced muscle damage in recreationally active males.

This investigation examined the effects of passive blood flow restriction (pBFR) on indices of exercise-induced muscle damage (EIMD) in recreationally active males. Fifteen males completed six consecutive visits (&#xb1;2&#x2009;hours). Participants completed 3&#x2009;&#xd7;&#x2009;25 maximal, unilateral, isokinetic (60&#xb0;&#xb7;s-1), concentric-eccentric leg extensions on both legs. Each leg was randomly assigned to receive pBFR (80% arterial occlusion pressure) or sham (20&#x2009;mmHg) at 0, 24, 48, 72, and 96&#x2009;hours post-EIMD. Perceived muscle soreness, range of motion (ROM), pain pressure threshold (PPT), concentric peak torque (CPT), and maximal voluntary isometric contraction (MVIC) torque were assessed and analyzed using separate linear mixed-effects models. Perceived muscle soreness increased at 24&#x2009;hours (mean difference [meandiff] = 4.9 au; p&#x2009;<&#x2009;0.001) and recovered by 96&#x2009;hours (p&#x2009;=&#x2009;0.482), with no differences between conditions (p&#x2009;=&#x2009;0.450). ROM (meandiff&#x2009;=&#x2009;-3.1&#xb0;; p&#x2009;=&#x2009;0.040), PPT (meandiff&#x2009;=&#x2009;-1.63 kgf; p&#x2009;<&#x2009;0.001), CPT (meandiff&#x2009;=&#x2009;-27.7&#x2009;Nm; p&#x2009;<&#x2009;0.001), and MVIC torque (meandiff&#x2009;=&#x2009;-30.8&#x2009;Nm; p&#x2009;<&#x2009;0.001) decreased at 24&#x2009;hours, with recovery occurring between 48-96&#x2009;hours. Condition-specific differences were observed for ROM (meandiff&#x2009;=&#x2009;2.5&#xb0;; p&#x2009;<&#x2009;0.001), PPT (meandiff&#x2009;=&#x2009;0.49 kgf; p&#x2009;=&#x2009;0.005), CPT (meandiff&#x2009;=&#x2009;6.2&#x2009;Nm; p&#x2009;=&#x2009;0.020), and MVIC torque (meandiff&#x2009;=&#x2009;7.1&#x2009;Nm; p&#x2009;=&#x2009;0.044), which were greater in pBFR than sham. These findings suggested that pBFR may reduce impairments in ROM, PPT, CPT, and MVIC torque following EIMD, despite a similar recovery trajectory between conditions.

Premeal insulin administration lowers postprandial blood glucose and increases myocardial microvascular blood flow in people with type 1 diabetes: a randomised, crossover clinical trial.

AIMS/HYPOTHESIS: We aimed to evaluate whether prandial insulin timing affects vascular function in people with type 1 diabetes. Our hypothesis was that premeal insulin administration would lead to greater myocardial microvascular blood flow (MBF) via blunting postprandial hyperglycaemia. METHODS: People with type 1 diabetes between 18 and 35 years of age with BMI <30 kg/m2 underwent two protocols with a 1:1 randomised crossover design wherein prandial insulin was injected either 15 min before or 15 min after meal intake began. To provide a physiological comparison, age-, sex- and BMI-matched control participants completed one study where they consumed the same meal but received no exogenous insulin. Glucose, insulin, vascular function (including ultrasound measures of myocardial and skeletal muscle microvascular perfusion, aortic stiffness, brachial artery endothelial function) and biomarkers of systemic inflammation and endothelial dysfunction were assessed at baseline and then 2 h after meal ingestion within each protocol. The primary outcome was change in myocardial MBF within each protocol. Study personnel assessing outcomes were masked to group assignment. RESULTS: Eighteen people with type 1 diabetes and 18 matched control participants were analysed within each protocol. Glucose area under the curve was significantly greater (p=0.015) in the postmeal insulin study compared with the premeal insulin study in participants with type 1 diabetes. Myocardial microvascular flow velocity significantly increased (p=0.031) with premeal insulin administration in people with type 1 diabetes and this consequently led to greater myocardial MBF (p=0.044). There were no changes in myocardial MBF within the other protocols. Changes in vital signs were similar between all protocols. CONCLUSIONS/INTERPRETATION: Appropriately timed premeal insulin led to lower postprandial blood glucose along with increased myocardial MBF in people with type 1 diabetes. Further work is needed to determine the underlying aetiology of these changes. TRIAL REGISTRATION: ClinicalTrials.gov NCT04730882.

Psychotherapy vs antidepressants in heart failure: Impact of adherence.

BACKGROUND: Depression affects nearly half of patients with heart failure (HF), which is associated with increased morbidity and reduced health-related quality of life (HRQoL). This secondary per-protocol analysis of a previously published randomized trial evaluated the behavioral activation (BA) versus antidepressant medication (MEDS) among patients with depression and HF who adhered to study interventions. METHODS: This analysis is based on a pragmatic randomized comparative-effectiveness trial conducted from 2018 to 2022, with a 1-year follow-up. 416 participants diagnosed with HF and a DSM-5 depressive disorder were randomized to BA or MEDS, and the current analysis examined outcomes according to treatment adherence. OUTCOMES: The primary outcome was depressive symptom severity (PHQ-9) at 6&#xa0;months, and the secondary outcomes were physical and mental HRQoL (SF-12v2-PC and SF-12v2-MC, respectively) and HF-specific HRQoL (Kansas City Cardiomyopathy Questionnaire; KCCQ) overall and clinical scores (KCCQ-OS and KCCQ-CS), at 3, 6, and 12&#xa0;months. High adherence was defined as completion of >75-100% of intervention components. Overall adherence rates were similar between BA and MEDS. At 6&#xa0;months, among patients with >75-100% adherence who followed treatment as directed in both arms, BA was associated with higher Mental HRQoL (SF-12v2-MC: 5.22; 95% CI: 0.72 to 9.72; p&#xa0;=&#xa0;0.023) and higher HF-specific HRQoL (KCCQ-OS: 16.08; 95% CI: 7.20 to 24.97; p&#xa0;<&#xa0;0.001); (KCCQ-CS: 16.04; 95%CI: 7.05 to 25.02; p&#xa0;<&#xa0;0.001) compared to MEDS. There were no significant differences in depressive symptoms or physical HRQoL at 6&#xa0;months. INTERPRETATION: Both BA and MEDS were equally effective treatments for depression in HF. However, among highly adherent patients, BA was associated with greater improvements in mental and HF-specific HRQoL than MEDS. FUNDING/SUPPORT: The study was funded by PCORI Award Number: 2017C2-7716.

[Moxibustion combined with Jianpi Wenshen formula for cancer-related anorexia of spleen-kidney yang deficiency: a randomized controlled trial].

OBJECTIVE: To observe the clinical efficacy of moxibustion combined with Jianpi Wenshen formula in treating cancer-related anorexia of spleen-kidney yang deficiency. METHODS: A total of 80 patients with cancer-related anorexia of spleen-kidney yang deficiency were randomized into an observation group and a control group, with 40 cases in each group.Jianpi Wenshen formula was given orally in the control group. On the basis of the treatment in the control group, moxibustion was applied at bilateral Zusanli (ST36), Neiguan (PC6) and Zhongwan (CV12), Guanyuan (CV4), Mingmen (GV4) in the observation group, once daily for the first 15 days, then once every other day. Both groups were treated for 4 weeks. The scores of appetite, Karnofsky performance status (KPS), nutritional risk screening 2002 (NRS-2002), and patient-generated subjective global assessment (PG-SGA), as well as the serum levels of interferon-&#x3b3; (IFN-&#x3b3;) and C-reactive protein (CRP)were observed before and after treatment, and the clinical efficacy was evaluated after treatment in the two groups. RESULTS: After treatment, the scores of appetite, NRS-2002, PG-SGA, and the serum levels of IFN-&#x3b3; and CRP were decreased compared with those before treatment in the two groups (P<0.001, P<0.05, P<0.01), and the above indexes in the observation group were lower than those in the control group (P<0.05, P<0.001); the KPS scores were increased in the two groups compared with those before treatment (P<0.001, P<0.05), and the KPS score in the observation group was higher than that in the control group (P<0.001). The marked response rate was 57.5% (23/40) in the observation group, which was higher than 30.0% (12/40) in the control group (P<0.05). CONCLUSION: Moxibustion combined with Jianpi Wenshen formula can effectively improve appetite and overall status, and reduce the levels of IFN-&#x3b3; and CRP in patients with cancer-related anorexia of spleen-kidney yang deficiency.

Effect of demographic characteristics on the outcome of prostate cancer salvage radiotherapy: Analysis from a randomized controlled trial.

BACKGROUND: This study investigated the impact of advanced molecular imaging, race, socioeconomic status, and metabolic dysregulation on the outcome of salvage radiotherapy (sRT) for prostate cancer recurrence in a clinical trial setting. METHODS: The authors randomized post-prostatectomy men with detectable prostate-specific antigen to sRT guided by conventional imaging (arm A) or 18F-fluciclovine-positron emission tomography/computed tomography (arm B) and followed them up for up to 48 months to determine failure-free survival (FFS). The authors computed socioeconomic status (SES) and allostatic load (AL) scores to quantify socioeconomic status and level of metabolic dysregulation. They stratified patients by race as African American men (AAM) versus men of other races (MOR) and compared FFS between them using the z-test. RESULTS: Eighty-one (AAM&#xa0;=&#xa0;29, MOR&#xa0;=&#xa0;52) and 76 (AAM&#xa0;=&#xa0;26, MOR&#xa0;=&#xa0;50) men completed per-protocol sRT in arms A and B, respectively. Across study arms, AAM showed a higher FFS rate than MOR (72.8% [95% CI, 53.8%-85.0%] vs. 58.7% [95% CI, 46.6%-68.9%]; p&#xa0;=&#xa0;.002). In arm A, FFS rate was better for AAM than MOR, (64.0% [95% CI, 34.4%-82.9%] vs. 45.3% [95% CI, 28.8%-60.4%]; p&#xa0;=&#xa0;.008). In arm B, FFS improved for both groups but less so for AAM, (81.5% [95% CI, 57.2%-92.7%] vs. 73.0% [95% CI, 56.3%-84.1%]; p&#xa0;=&#xa0;.131). The authors found lower SES scores and higher AL scores for AAM in both study arms than MOR. CONCLUSION: Despite lower socioeconomic status and higher burden of metabolic dysregulation, in a clinical trial setting that controls for disparities in health care access, AAM have a more favorable sRT outcome than MOR.

Angiography-Based Index of Microcirculatory Resistance in Assessing the MVO and Infarct Size in STEMI Patients.

OBJECTIVES: To evaluate angiography-based index of microcirculatory resistance (angio-IMR) in assessing microvascular obstruction (MVO) and infarct size (IS) in ST-segment elevation myocardial infarction (STEMI). BACKGROUND: The effect of thrombolysis on post-percutaneous coronary intervention (PCI) angio-IMR, and its associations with MVO and IS remains unclear. METHODS: One hundred twenty-three STEMI patients randomized to receive 5&#x2009;mg intravenous bolus of recombinant staphylokinase (r-SAK) or normal saline (NS) before PCI were recruited. Angio-IMR was computed in infarct-related arteries. MVO and IS were detected by cardiac magnetic resonance imaging. RESULTS: Compared with NS group, r-SAK group exhibited numerically lower post-PCI angio-IMR (39.12 U vs. 42.57 U; p&#x2009;=&#x2009;0.567), MVO (54.0% vs. 70.9%; p&#x2009;=&#x2009;0.059), MVO extent (0.70% vs. 1.90%; p&#x2009;=&#x2009;0.101) and IS (21.30% vs. 24.50%; p&#x2009;=&#x2009;0.079). Post-PCI angio-IMR was positively correlated with MVO extent (&#x3c1;&#x2009;=&#x2009;0.347; p&#x2009;<&#x2009;0.001) and IS (&#x3c1;&#x2009;=&#x2009;0.324; p&#x2009;<&#x2009;0.001). Receiver operating characteristic analyses showed moderate diagnostic performance of angio-IMR for MVO (area under the curve [AUC] = 0.750; p&#x2009;<&#x2009;0.001), MVO&#x2009;>&#x2009;2.6% (AUC&#x2009;=&#x2009;0.735; p&#x2009;<&#x2009;0.001) and IS&#x2009;>&#x2009;25% (AUC&#x2009;=&#x2009;0.712; p&#x2009;<&#x2009;0.001). The exploratory optimal cut-off values for these endpoints were approximately 40&#x2009;U. CONCLUSIONS: In STEMI patients, a single bolus of r-SAK before PCI was associated with numeric reductions in post-PCI angio-IMR, MVO, MVO extent and IS. Additionally, angio-IMR exhibited a significantly positive correlation with both MVO extent and IS, demonstrating the diagnostic value of this wire-free method for assessing microvascular injury.

Assessment of the safety and efficacy of sodium pentaborate pentahydrate in individuals with overweight and obesity: a randomized, double-blind, placebo-controlled, phase 1/2 dose-finding trial.

The present study aimed to examine the short-term safety and tolerability of sodium pentaborate pentahydrate (NaB) and to explore preliminary efficacy and dose selection as secondary objectives in individuals with overweight or obesity. In this randomized, double-blind, placebo-controlled, phase 1/2 trial, conducted from July 2024 to January 2025, 177 adults with overweight or obesity were randomized, of whom 116 completed the 12-week trial. Participants received placebo or NaB at doses of 200, 400, 600, 800, or 1,000&#x2009;mg for 12&#x2009;weeks, alongside a standardized diet and exercise programme. The primary safety objective was to investigate short-term safety and tolerability through adverse events, hypoglycaemic episodes, gastrointestinal adverse events, and changes in haematological and biochemical parameters. The primary exploratory efficacy outcome was percentage change in body weight from baseline to week 12. Secondary and exploratory efficacy outcomes included body weight, body mass index (BMI), waist and hip circumferences, waist-to-hip ratio, glycaemic markers, lipid parameters, and blood pressure. Baseline characteristics were broadly similar across groups (all p&#x2009;&#x2265;&#x2009;0.05), and no major short-term safety signal was observed. Mean body weight decreased in the 400&#x2009;mg (-2.6&#x2009;kg), 600&#x2009;mg (-1.2&#x2009;kg), and 1,000&#x2009;mg groups (-3.1&#x2009;kg). Compared with placebo, the 1,000&#x2009;mg dose resulted in the largest reductions in body weight (mean difference, -2.30&#x2009;kg; p&#x2009;=&#x2009;0.01) and BMI (mean difference, -0.85&#x2009;kg/m2; p&#x2009;=&#x2009;0.02). The 1,000&#x2009;mg dose showed preliminary efficacy for reducing body weight and BMI over 12&#x2009;weeks compared with placebo, with no major short-term safety signal and no clinically meaningful changes in renal, hepatic, or haematological markers. All reported adverse events were mild. These short-term findings are exploratory and require confirmation in future phase 3 trials with extended follow-up to investigate long-term safety and efficacy.

Efficacy and safety of thulium fiber laser versus conventional holmium:YAG laser in anatomical endoscopic enucleation of the prostate: a systematic review and pairwise meta-analysis.

PURPOSE: Anatomical endoscopic enucleation is an established treatment for benign prostatic obstruction. Whether thulium fiber laser enucleation (ThuFLEP) improves outcomes over conventional holmium:YAG laser enucleation (HoLEP) remains uncertain. We compared the efficacy and safety of ThuFLEP versus non-MOSES-modulated HoLEP. METHODS: We performed a PRISMA-compliant systematic review and pairwise meta-analysis of randomised and comparative cohort studies comparing ThuFLEP and conventional HoLEP in adult men. Six databases were searched. Outcomes included International Prostate Symptom Score (IPSS), IPSS quality-of-life score, maximum urinary flow rate (Qmax), post-void residual volume, hospital stay, and complications. Risk of bias and certainty of evidence were assessed with RoB 2/ROBINS-I and GRADE. RESULTS: Seven non-overlapping comparative populations in eight publications included 3,509 patients. ThuFLEP was associated with a small statistically significant reduction in IPSS at 3&#xa0;months (mean difference [MD] -1.04 points, 95% confidence interval [CI] -1.81 to -0.28) of uncertain clinical relevance. Qmax differences were small and directionally inconsistent across follow-up (favouring HoLEP at 3&#xa0;months and ThuFLEP at 6 and 12&#xa0;months) and derived mainly from retrospective cohorts, with neutral randomised subgroups. Stress and urge urinary incontinence were less frequent overall (RR 0.75, 95% CI 0.58 to 0.96, and RR 0.39, 95% CI 0.22 to 0.68), but both estimates depended on one large registry cohort and were not robust to its exclusion. Most other complications and hospital stay showed no clear between-group difference. Limitations include few studies per outcome, heterogeneity, sparse safety events, inconsistent prostate-specific antigen reporting, and mostly low/very low certainty evidence. CONCLUSION: ThuFLEP and conventional HoLEP are clinically comparable with no definitive superiority of either laser. Platform selection should be individualised according to surgeon expertise, institutional resources, and patient characteristics. Future trials should standardise cost-effectiveness outcomes and investigate whether the distinct laser-tissue interactions impact adenoma clearance, PSA reduction, enucleation completeness, and long-term durability.

Clopidogrel vs Aspirin According to Diabetes Mellitus: A Prespecified Analysis of the SMART-CHOICE 3 Trial.

BACKGROUND: Recent trials support the superior efficacy of clopidogrel compared to aspirin monotherapy after completion of dual antiplatelet therapy (DAPT) in patients who have undergone percutaneous coronary intervention (PCI). However, limited evidence is available in patients with diabetes mellitus (DM). OBJECTIVES: This study sought to evaluate the comparative efficacy and safety of clopidogrel vs aspirin monotherapy according to the presence of DM. METHODS: This was a prespecified analysis of the SMART-CHOICE 3 trial, which was a multicenter, open-label, randomized controlled trial comparing clopidogrel vs aspirin monotherapy in patients with complex coronary lesions or high-risk clinical characteristics. From August 2020 to July 2023, a total of 5,506 patients who underwent PCI and standard DAPT duration and had complex coronary lesions, DM, or previous myocardial infarction, were randomized to clopidogrel or aspirin monotherapy groups. The primary endpoint was major adverse cardiac and cerebrovascular events (MACCE), which was defined as a composite of death from any cause, myocardial infarction, or stroke. RESULTS: Of 5,506 patients, 2,089 had DM (1,039 in the clopidogrel group and 1,050 in the aspirin group). At a median follow-up of 2.3 years (IQR: 1.6-3.0 years), DM patients had a higher risk of MACCE compared to non-DM patients (6.8% vs 4.7%; HR: 1.44, 95% CI: 1.10-1.87; P = 0.008). Clopidogrel showed a significantly lower risk of MACCE than aspirin in DM patients (4.5% vs 9.1%; HR: 0.57, 95% CI: 0.38-0.86; P = 0.008). There was no significant interaction between DM and antiplatelet monotherapy regarding MACCE (P for interaction = 0.124). The risk of bleeding was comparable between the 2 groups in DM patients (2.9% vs 2.9%; HR: 1.06, 95% CI: 0.57-1.95; P = 0.855). CONCLUSIONS: Among DM patients who completed the standard duration of DAPT after PCI, clopidogrel monotherapy was associated with a lower risk of a composite of death from any cause, myocardial infarction, and stroke compared with aspirin monotherapy, without increased rates of bleeding. There was no significant interaction between DM and antiplatelet monotherapy with respect to MACCE.

Effects of Exergame Balance Training with Variable Cognitive Motor Challenges on Serum BDNF, p-tau181, and Cognitive Functions in Adults with Mild Cognitive Impairment: A Randomized Trial.

INTRODUCTION: Cognitive-motor exergame balance training may increase attentional demands and neuronal processing, potentially affecting serum levels of brain-derived neurotrophic factor (BDNF), A&#x3b2;1-42, and p-tau181, as well as train cognitive abilities in adults with mild cognitive impairment (MCI). This study aimed to compare the effects of exergame balance training of mild, moderate, high-difficulty, and Wii Fit&#x2122; groups on blood serum levels of BDNF, A&#x3b2;1-42, p-tau181, and cognition function in adults with MCI. METHODS: In this four-arm, parallel group randomized clinical trial, 97 adults with MCI were randomly assigned to exergame balance training groups of mild, moderate, high-difficulty, and Wii Fit exergame as a control group. All participants received 40 min/session, 3 times/week for 8 weeks. Assessment of serum levels of p-tau181, A&#x3b2;1-42, BDNF, and cognitive functions was conducted at baseline, after weeks 4 and 8. A mixed-model analysis of covariance was used, with post-baseline measurements (weeks 4 and 8) specified as the within-subject factor and the corresponding baseline value entered as a covariate to adjust for initial between-group variability. RESULTS: A significant group &#xd7; time interaction was found for BDNF, F(3,92) = 6.413, P = 0.017, &#x3b7;p2 = 0.181; p-tau181, F(3,92) = 4.640, P = 0.040, &#x3b7;p2 = 0.138; attention, F(3,92) = 4.171, P = 0.045, &#x3b7;p2 = 0.057; abstraction, F(3,92) = 4.263, P = 0.043, &#x3b7;p2 = 0.058; and visuospatial skills, F(3,92) = 6.931, P < 0.001, &#x3b7;p2 = 0.234. CONCLUSION: Cognitive-motor challenge-based exergame balance training was associated with an increase in serum BDNF, a reduction in p-tau181. In contrast, the A&#x3b2;1-42 levels remained stable. These changes were accompanied by improvement in selective cognitive functions (attention, abstraction, and visuospatial skills) in individuals with MCI. Greater effects were observed in moderate and high-difficulty groups, suggesting the importance of intervention intensity in promoting cognitive and neurobiological outcomes in MCI.

Exercise Snacks Are Feasible to Perform in the Real World and Improve Physical Capacity for Adults Living With Non-Insulin Treated Type 2 Diabetes: A Randomised Trial.

AIMS: To investigate the feasibility and preliminary efficacy of a 12-week remotely-delivered exercise snacks (ES) intervention in adults with type 2 diabetes. MATERIAL AND METHODS: Insufficiently active adults with type 2 diabetes (N&#x2009;=&#x2009;69; 46 females; mean age&#x2009;&#xb1;&#x2009;SD: 58&#x2009;&#xb1;&#x2009;11&#x2009;years) were randomised to an ES or mobility/stretching comparator group (CON), which involved 4&#x2009;&#xd7;&#x2009;1-min bouts of either vigorous or low intensity exercise, respectively, on &#x2265;&#x2009;5&#x2009;days/week. The primary outcome was feasibility based on adherence. Secondary outcomes included exercise enjoyment (1-7 scale), rating of perceived exertion (RPE; 0-10 scale), heart rate (HR), haemoglobin A1c (HbA1c), blood biomarkers of cardiometabolic health, 30-s sit-to-stand capacity, grip strength, estimated maximal oxygen uptake, and anthropometrics. RESULTS: Weekly adherence (estimated marginal mean [95% confidence interval]: 18 bouts [16-21] for both groups; p&#x2009;=&#x2009;0.99) and total enjoyment (ES: 4.5 [4.1-4.8] vs. CON: 4.3 [4.0-4.7]; p&#x2009;=&#x2009;0.64) were high and not different between groups. Despite higher RPE (5.7 [5.4-6.1]) and peak HR (73 [70-77] % of age-predicted HR maximum) in ES versus CON (2.0 [1.7-2.4] and 61 [58-64] % of age-predicted HR maximum, respectively) (all p&#x2009;<&#x2009;0.001), there were no between-group differences in the change in any secondary outcome (all p&#x2009;>&#x2009;0.05) except for greater sit-to-stand capacity in ES after training (between-group effect estimate [95% confidence interval]: 1.9 repetitions [0.3-3.4]; p&#x2009;=&#x2009;0.02). CONCLUSIONS: Exercise snacks were feasible to perform in the real world and improved sit-to-stand capacity to a greater extent than CON in adults living with type 2 diabetes.

Alterations in Spatiotemporal Parameters in Patients With Lower-Limb Amputation: A Systematic Review With Meta-Analysis.

OBJECTIVES: To evaluate differences in spatiotemporal gait parameters in individuals with transfemoral (TFA) and transtibial amputation (TTA) compared with physically able individuals. METHODS: This systematic review with meta-analysis was conducted according to the MOOSE guidelines. Cross-sectional studies or clinical trials that assessed spatiotemporal gait parameters in adults with unilateral TFA or TTA were included. Searches were performed in Medline (via PubMed), CINAHL, Scopus, LILACS, Cochrane Library, and Embase using descriptors related to amputation and gait. Risk of bias was assessed using the Joanna Briggs Institute scale for cross-sectional studies, whereas the meta-analysis was performed using quantitative data for the following outcomes: walking speed, step length, stride length, step width, cadence, stance time, swing time, step time, or stride time. RESULTS: A total of 12 cross-sectional studies involving 150 individuals with amputation (86 TTA and 64 TFA) and 138 healthy controls were included. Meta-analysis demonstrated a significant reduction in walking speed (mean difference of -0.24; 95% CI -0.32 to -0.17; p&#xa0;<&#xa0;0.0001; I2&#xa0;=&#xa0;61%) and cadence (mean difference of -6.01; 95% CI -9.69 to -2.34; p&#xa0;=&#xa0;0.001; I2: 54%) in patients with amputation compared with healthy individuals. A reduction in stride length (mean difference of -11.71; 95% CI -23.37 to -0.04; p&#xa0;=&#xa0;0.05; I2: 85%) and an increase in step width (mean difference of 5.22; 95% CI 2.99 to 7.45; p&#xa0;<&#xa0;0.0001; I2: 71%) were also observed. Step time showed no significant difference between groups (mean difference of 0.06; 95% CI -0.01 to 0.14; p&#xa0;=&#xa0;0.11; I2: 93%). Patients with TFA amputation exhibited greater impairment in gait variables, particularly cadence, when compared with a healthy individual. CONCLUSIONS: Patients with lower limb amputation present with functionally compromised gait, characterized by reduced walking speed. Increased step width and reduced stride length are findings that may suggest compensatory strategies during gait and improved balance, which are important requirements for amputee patients. These findings reinforce the need for rehabilitation interventions focused on improving propulsion and postural safety. TRIAL REGISTRATION: PROSPERO: CRD42024620098.

Efficacy and Safety of iGlarLixi Versus IDegAsp by Baseline Age, Disease Duration and HbA1c in Chinese People With Type 2 Diabetes: Post Hoc Analyses of the Soli-D Study.

AIMS: To compare the efficacy and safety of insulin glargine 100&#x2009;U/mL plus lixisenatide (iGlarLixi) with insulin degludec plus insulin aspart (IDegAsp) by baseline age, Type 2 diabetes (T2D) duration and glycated haemoglobin (HbA1c) in the Soli-D study. MATERIALS AND METHODS: In Soli-D, Chinese adults with T2D suboptimally controlled on oral antidiabetic drugs (OADs) were randomized to iGlarLixi or IDegAsp for 24&#x2009;weeks. These post hoc analyses evaluated glycaemic efficacy, insulin dose, body weight and hypoglycaemia outcomes in subgroups defined by baseline age (<&#x2009;65, &#x2265;&#x2009;65&#x2009;years), T2D duration (<&#x2009;10, &#x2265;&#x2009;10&#x2009;years) and HbA1c (&#x2265;&#x2009;7% to &#x2264;&#x2009;8% [&#x2265;&#x2009;53 to &#x2264;&#x2009;64&#x2009;mmol/mol], >&#x2009;8% to &#x2264;&#x2009;9% [>&#x2009;64 to &#x2264;&#x2009;75&#x2009;mmol/mol], >&#x2009;9% [>&#x2009;75&#x2009;mmol/mol]). RESULTS: Among 582 participants (iGlarLixi n&#x2009;=&#x2009;291; IDegAsp n&#x2009;=&#x2009;291), baseline age was <&#x2009;65&#x2009;years in 442 and &#x2265;&#x2009;65&#x2009;years in 140; T2D duration was <&#x2009;10&#x2009;years in 366 and &#x2265;&#x2009;10&#x2009;years in 216; and HbA1c was &#x2265;&#x2009;7% to &#x2264;&#x2009;8% in 205, >&#x2009;8% to &#x2264;&#x2009;9% in 209 and >&#x2009;9% in 168. At Week 24, HbA1c reductions were greater with iGlarLixi versus IDegAsp, with no treatment-by-subgroup interactions for baseline age, T2D duration or HbA1c. Change in other glycaemic outcomes, insulin dose and body weight generally showed no interaction across subgroups. Total insulin daily doses during treatment and hypoglycaemia event rates were consistently lower with iGlarLixi versus IDegAsp in all subgroups. CONCLUSIONS: iGlarLixi provides improved glycaemic control at lower insulin doses with reduced risk of hypoglycaemia in Chinese adults with suboptimally controlled T2D on OADs, regardless of baseline age, disease duration or HbA1c.

Efficacy and safety of add-on topiramate vs. metformin on cardiometabolic profile in patients of schizophrenia on atypical antipsychotics with metabolic syndrome: an active-controlled, rater-blinded, parallel-design randomized controlled trial.

BACKGROUND: Metabolic syndrome is common among patients with schizophrenia, but current treatment options are limited, with metformin being the most studied. While placebo-controlled studies suggest potential benefits of topiramate, comparative efficacy and safety data are lacking. This study aimed to compare the efficacy and safety of topiramate versus metformin for treating metabolic syndrome and reducing cardiovascular risks among patients with schizophrenia. METHODS: A randomised, open-label, parallel-group clinical trial was conducted on 60 patients of schizophrenia with metabolic syndrome, randomised equally to receive either topiramate (50&#xa0;mg/day) or metformin (1000&#xa0;mg/day) for eight weeks. Primary outcome was cardiovascular risk score (QRISK3), and secondary outcomes were LDL&#x2236;HDL ratio, insulin resistance (HOMA-IR), positive and negative syndrome scale (PANSS), Montreal Cognitive Assessment (MoCA) and clinical global impression-Schizophrenia scale (CGI-SCH) scores. RESULTS: Over the study period, QRISK3 scores improved significantly in both groups [topiramate: MD&#x2009;=&#x2009;0.61 (0.02 to 1.21), p&#x2009;=&#x2009;0.04; metformin: MD&#x2009;=&#x2009;0.45 (0.07 to 0.83), p&#x2009;=&#x2009;0.02], with no significant between-group difference in unadjusted analysis (p&#x2009;=&#x2009;0.648). However, ANCOVA adjusting for baseline QRISK3 revealed a significantly greater improvement in the topiramate group (&#x3b2; = -0.324, p&#x2009;=&#x2009;0.043). Metformin showed significant within-group improvements in LDL: HDL ratio and HOMA-IR; however, ANCOVA adjusting for baseline HOMA-IR showed the between-group difference remained non-significant (&#x3b2; = -1.209, p&#x2009;=&#x2009;0.078). Both groups showed significant improvements in PANSS and CGI-SCH scores, with no significant between-group differences in MoCA scores. A moderate correlation between the QRISK3 change, the PANSS change, and the CGI-SCH-I scores was observed in the topiramate group and the total population. Regression analysis identified PANSS change as a predictor of QRISK3 improvement. CONCLUSION: Topiramate demonstrated comparable, and on adjusted analysis superior, cardiovascular risk reduction compared to metformin, supporting its use as a viable alternative in the management of metabolic syndrome in patients with schizophrenia on atypical antipsychotics, particularly where metformin is contraindicated.

A novel neoadjuvant immunotherapy confers improved overall survival in oral cancer patients with low tumor PD-L1 expression The IT-MATTERS Clinical trial - Prognostic role of tumor PD-L1 expression.

OBJECTIVE: Five-year overall survival (OS) remains&#xa0;<&#xa0;50% for patients with resectable, locally advanced (LA) primary oral squamous cell carcinoma (OSCC) and soft palate, receiving current standard of care (SOC). The aim of our study was to examine neoadjuvant Leukocyte Interleukin Injection (LI) with CIZ (intravenous low dose cyclophosphamide, indomethacin and zinc multivitamins) effect on OS, in low-risk (LR) OSCC patients. PATIENTS AND METHODS: In a randomized, controlled Phase 3 trial, treatment-na&#xef;ve locally advanced patients, with stage III/IVa OSCC and soft-palate cancer, had surgical tumor samples assessed for pre-defined thresholds of PD-L1 tumor proportion score (TPS). OS was analyzed using proportional hazard models for LI&#xa0;+&#xa0;CIZ&#xa0;+&#xa0;SOC vs SOC, in the intention-to-treat (ITT) population. RESULTS: OS was superior in low risk (LR) patients receiving LI&#xa0;+&#xa0;CIZ&#xa0;+&#xa0;SOC compared to SOC; OS advantage hazard ratio (HR) 0.64, p&#xa0;=&#xa0;0.0569 (without selecting for N0, PD-L1 TPS&#xa0;<&#xa0;10%), and the Kaplan-Meier (K-M) lifetable achieved significance (log rank p&#xa0;=&#xa0;0.0340) favoring LI&#xa0;+&#xa0;CIZ&#xa0;+&#xa0;SOC vs SOC. Applying the selection criteria (cN0 and TPS&#xa0;<&#xa0;10%) to ITT, OS reached HR 0.34p&#xa0;=&#xa0;0.0012, Kaplan-Meier log rank p&#xa0;=&#xa0;0.0015. The ITT LR cohort (cN0 and TPS&#xa0;<&#xa0;10%) achieved a HR 0.26 (p&#xa0;=&#xa0;0.0023), Kaplan-Meier log rank p&#xa0;=&#xa0;0.0013, supported by progression free survival (PFS) HR 0.43, p&#xa0;=&#xa0;0.0178, Kaplan-Meier log rank p&#xa0;=&#xa0;0.0431, with 32% absolute survival advantage over control at 60&#xa0;months. CONCLUSIONS: Significant OS prolongation was observed in ITT population for LI&#xa0;+&#xa0;CIZ&#xa0;+&#xa0;SOC vs SOC, in LR and in ITT LR cN0, PD-L1TPS&#xa0;<&#xa0;10% cohort having locally advanced squamous cell carcinoma tumors in oral cavity/soft-palate.

Timing and Dose Matter: Late High-Speed Exposure and Higher High-Intensity Acceleration Volumes Reduce Hamstring Reinjury Risk in Elite Male Football (Soccer).

OBJECTIVES: The aims of this study were to (a) investigate whether the timing and magnitude of exposure to high-speed running (HSR), sprinting, and high-intensity accelerations during on-field rehabilitation after hamstring strain injury were associated with reinjury risk and (b) examine changes in match running performance upon return to play (RTP). DESIGN: Retrospective cohort study. METHODS: Data from 95 elite male football (soccer) players from five professional clubs competing in major European and Middle Eastern leagues were analyzed. Players with complete rehabilitation load profiles were included in the 2-month and 6-month reinjury analysis. Modified Poisson regression assessed associations between rehabilitation load characteristics and reinjury risk. Match running performance (HSR distance, sprint distance, and high-intensity accelerations per minute) during the five matches before injury and the first five matches after RTP was compared using paired t-tests for the entire cohort. RESULTS: Late introduction of HSR, sprinting, and high-intensity accelerations during rehabilitation (ie, &#x2265; 60% of rehabilitation progression) was associated with a significantly lower reinjury risk at 2 months (relative risk [RR] range = 0.948-0.969; P < .01) and 6 months (RR range = 0.964-0.979; P < .05). Higher daily exposure to high-intensity accelerations once introduced was protective (RR = 0.861 (0.778-0.951)). There were no meaningful associations between total volume of HSR or sprinting and reinjury. Match running performance metrics did not differ between pre-injury and post-RTP matches (all P > .05). Changes in performance were not correlated with rehabilitation load characteristics. CONCLUSION: The timing of high-intensity running exposure during on-field rehabilitation appeared associated with a lower hamstring reinjury risk. Delaying the introduction of HSR, sprinting, and accelerations, followed by a structured and progressive build-up, was associated with lower risk of reinjury without compromising the subsequent match performance of elite male football players.

Exploring the role of successful exercise-induced body weight loss on cardiometabolic health in individuals with metabolic syndrome.

BACKGROUND AND AIM: High-intensity interval training (HIIT) is known to improve cardiorespiratory fitness (i.e., VO2MAX), a key marker of cardiometabolic health in individuals with metabolic syndrome (MetS). Nonetheless, body weight loss is widely recognized as a crucial factor in reducing insulin resistance and improving metabolic risk factors. Thus, we aimed to determine the importance of body weight loss following exercise training on improving MetS. METHODS AND RESULTS: Two hundred and twenty-eight adults (55.3&#xa0;&#xb1;&#xa0;7.9&#xa0;yr) with overweight/obesity (32.5&#xa0;&#xb1;&#xa0;4.6&#xa0;kg&#xb7;m-2) and MetS were randomized to: a) standard health care non-exercise group (CONTROL group, N=58) or b) standard health care plus 16 weeks of HIIT (EXER group, N=170). MetS (MetS z-score), insulin resistance (HOMA-IR), cardiorespiratory fitness (VO2PEAK), maximal cycling power (WPEAK), and body weight/composition were assessed. After intervention, EXER group participants were divided according to their weight loss response to training: i) those achieving the weight loss predicted from estimated exercise energy expenditure (-BW group, n=78; -3.3&#xa0;&#xb1;&#xa0;2.2&#xa0;kg); ii) those not reaching the expected weight loss (=BW group, n=38; -0.7&#xa0;&#xb1;&#xa0;0.5&#xa0;kg); iii) and those who gained weight (+BW group, n=54; 1.1&#xa0;&#xb1;&#xa0;1.0&#xa0;kg). VO2PEAK significantly improved regardless of body weight loss response (-BW, 0.3&#xa0;&#xb1;&#xa0;0.3; =BW, 0.2&#xa0;&#xb1;&#xa0;0.3; +BW, 0.3&#xa0;&#xb1;&#xa0;0.2&#xa0;L&#xb7;min-1; all p&#xa0;<&#xa0;0.001) compared to CONTROL group (0.0&#xa0;&#xb1;&#xa0;0.3&#xa0;L&#xb7;min-1). However, significant improvements in MetS z-score (-0.31&#xa0;&#xb1;&#xa0;0.41) and HOMA-IR (-0.7&#xa0;&#xb1;&#xa0;1.6) were observed only in the -BW group (both p&#xa0;<&#xa0;0.001). CONCLUSIONS: Exercise recommendations should consider that greater improvements in MetS are observed when interventions are accompanied by successful body weight loss.

Hyper-oncotic albumin administration reduces mortality in acute Respiratory Distress Syndrome compared to crystalloid: a systematic review and meta-analysis.

BACKGROUND: To evaluate the association between albumin administration as volume replacement and mortality in adult ARDS patients, we performed this meta-analysis and trial sequential analysis (TSA). METHODS: We searched databases including PubMed, Science Direct, Scopus, Web of Science databases and Cochrane Central Register of Controlled Trials up to 12 December 2024. We screened trials that included adult ARDS patients and compared albumin with crystalloid. The 28-day mortality served as the primary endpoint, while the oxygenation change, the length of ICU stay and the length of hospital stay were designated as secondary outcomes. To clarify the differing concentrations of albumin, we formed two distinct subgroups: the hyper-oncotic albumin subgroup (&#x2265;20%) and the iso-oncotic albumin subgroup (4%&#x223c;5%). Statistical synthesis was performed with Cochrane Review Manager 5.4.1, employing random-effects models. To mitigate random errors, TSA was implemented with &#x3b1;&#x2009;=&#x2009;0.05 and &#x3b2;&#x2009;=&#x2009;0.20 parameters. RESULTS: The analysis incorporated 5 publications: 3 randomized controlled trials (RCTs) and 2 non-randomized studies (NRSs). Overall mortality was lower in the albumin group (33.2%, 97/292) than in the crystalloid group (44.9%, 133/296) (OR = 0.61, 95%CI 0.43-0.85, p&#x2009;=&#x2009;0.004). RCTs (n&#x2009;=&#x2009;204) showed no benefit (OR = 0.83, p&#x2009;=&#x2009;0.54), but NRSs (n&#x2009;=&#x2009;384) demonstrated reduced mortality (OR = 0.52, p&#x2009;=&#x2009;0.002). Hyper-oncotic albumin was associated with lower mortality in NRSs (OR = 0.40, p&#x2009;=&#x2009;0.02) but not in RCTs (OR = 0.74, p&#x2009;=&#x2009;0.57). Iso-oncotic albumin showed no benefit (OR = 0.88, p&#x2009;=&#x2009;0.72). Regarding the impact of albumin on oxygenation, significant improvements in oxygenation were observed only on the first (p&#x2009;=&#x2009;0.05) and second days (p&#x2009;<&#x2009;0.0001). The TSA indicated a continued need for high-quality RCTs. CONCLUSIONS: Our analysis suggests that hyper-oncotic albumin may reduce mortality and improve early oxygenation in ARDS patients compared to crystalloids. Larger RCTs are urgently needed to validate these findings and define their potential role in clinical management.
