Recurrent myocardial infarction identified by centralized troponin review: Insights from the MINT trial.

BACKGROUND: The utility of routine troponin testing to identify recurrent myocardial infarction (MI) after an incident MI is unclear. We assessed the incidence and prognosis of recurrent MIs identified from centralized troponin review in patients from the Myocardial Ischemia and Transfusion (MINT) trial. METHODS: The MINT trial randomized patients with acute MI and anemia to a liberal vs restrictive red blood cell transfusion strategy. Suspected recurrent MIs were identified through both site-report and centralized review of troponin levels collected for 3 days following randomization. Differences in cardiac, noncardiac, and all-cause death at 30 and 180 days were compared across patients with any site-reported MI, only centrally identified MI, and no recurrent MI. RESULTS: Among 3,504 patients, 275 (7.8%) had a recurrent MI within 30 days; 119 (43.3%) by site-report, and 156 (56.7%) by central troponin review only. Rates of cardiac and all-cause death at 30 and 180 days were highest for patients with site-reported MI, intermediate for centrally identified MI, and lowest for no recurrent MI; rates of noncardiac death did not vary. Patients with only centrally identified recurrent MI had an increased risk of cardiac death at 30 days (RR 1.9, 95% CI 1.0-3.4) and 180 days (RR 1.7, 95% CI 1.1-2.7) compared to those without recurrent MI. CONCLUSIONS: In patients with acute MI and anemia, centralized troponin review identified more than half of all recurrent MI events. Patients with centrally identified MI had a higher risk of cardiac death than those with no recurrent MI.

Adjunctive intermittent theta-burst stimulation for first-episode schizophrenia: A randomized clinical trial.

BACKGROUND: The efficacy of intermittent theta-burst stimulation (iTBS) combined with pharmacotherapy and psychotherapy in first-episode schizophrenia remains unclear. This study evaluated adjunctive iTBS with risperidone and cognitive behavioral therapy (CBT) and explored serum biomarkers indicating treatment response. METHODS: In this randomized, assessor-blind trial, 100 first-episode schizophrenia patients received either iTBS plus risperidone and CBT (iTBS group, n = 50) or risperidone and CBT alone (control, n = 50) for 3 months. The primary outcome was change in PANSS total score at 4 weeks and 3 months. Response was defined as a &#x2265; 50 % PANSS reduction. Secondary outcomes included cognitive function (MCCB subtests) and serum GDNF, cortisol, and dehydroepiandrosterone sulfate (DHEA-S) levels. RESULTS: The iTBS group showed significantly greater reduction in PANSS total scores than controls at both 4 weeks and 3 months (mean difference at 3 months: -13.3, 95 % CI: -16.8 to -9.8; P < 0.001), with a higher responder rate (76 % vs. 48 %). Significant improvements across all cognitive domains were observed in the iTBS group (all P < 0.001). Post-treatment, the iTBS group exhibited higher GDNF and lower cortisol and DHEA-S levels (all P < 0.001). A combined biomarker panel demonstrated superior discriminative performance for treatment efficacy (AUC=0.865 after cross-validation). Adverse events were comparable between groups. CONCLUSIONS: Adding iTBS to risperidone and CBT significantly improves clinical symptoms and cognitive function in first-episode schizophrenia. The combination of GDNF, cortisol, and DHEA-S shows promise as a composite biomarker for treatment response, though sham-controlled validation is warranted.

Chinese herbal medicine Xiangsu Hewei Granules in treating non-erosive gastroesophageal reflux disease with liver stomach stagnation heat syndrome: A multicentre, randomized, double-blind, placebo-controlled trial.

ETHNOPHARMACOLOGICAL RELEVANCE: Xiangsu Hewei Granules are an herbal preparation that has shown potential for controlling symptoms of nonerosive gastroesophageal reflux disease (NERD) in preliminary studies. However, high-quality randomized controlled evidence for its use in NERD remains lacking. AIM: To verify the efficacy and safety of Xiangsu Hewei Granules in treating NERD with liver stomach stagnation heat syndrome. MATERIALS AND METHODS: This randomized, double-blind, placebo-controlled, multicentre phase III trial included 480 patients (aged 18-65 years) with confirmed NERD (GerdQ&#x2265;8; negative H. pylori) and traditional Chinese medicine (TCM) liver stomach stagnation heat syndrome. Patients were randomized 3:1 to receive either Xiangsu Hewei Granules or placebo, thrice daily for 8 weeks. The primary outcomes were the effective rate of the response based on visual analog scale (VAS) scores for heartburn and acid regurgitation at week 8. The secondary outcomes included reductions in the TCM syndrome score, etc. RESULTS: 479 participants (mean age 48.5 years, SD10.2; 54.3% female) entered the full analysis set and safety set (360 tests group; 119 control group, 1 participant in the control group withdrawing before medication). At week 8, compared with the control group, the test group demonstrated significantly better effective rate of VAS score response for heartburn(76.39% vs 21.01%, 95% CI 55.38 (45.98, 62.94) %, p&#x202f;<&#x202f;0.01),acid regurgitation (79.72% vs 23.53%, 95% CI56.39 (46.90, 64.12) %, p&#x202f;<&#x202f;0.01), and TCM syndrome score (69.23% vs 30.13%, p&#x202f;<&#x202f;0.01) at week 8. CONCLUSION: In this selected population of NERD patients with liver-stomach stagnation heat syndrome (e.g., negative H. pylori, no pH-impedance phenotype, and low anxiety/depression scores), Xiangsu Hewei Granules demonstrated efficacy and safety in improving heartburn, acid regurgitation, and TCM syndrome scores. However, generalizability to the broader NERD population and its comparative effectiveness against standard proton pump inhibitor therapy require further investigation.

Effects of adjunctive memantine on executive function and global cognition in bipolar disorder (BD): A randomized, double-blind, placebo-controlled clinical trial.

BACKGROUND: Cognitive impairment contributes substantially to disability in bipolar disorder (BD), but effective pharmacologic options remain limited. This trial evaluated whether adjunctive memantine improves global cognition and executive function in BD. METHODS: In this double-blind, placebo-controlled randomized trial, patients with bipolar I disorder (B1D) receiving lithium and olanzapine were assigned to memantine or placebo. Memantine was titrated to 20&#xa0;mg/day over 6&#xa0;weeks. Cognitive outcomes were assessed at baseline, week 6, and week 18. Global cognition was measured with the Neurocognitive Assessment Battery (NuCog), and executive function with the Frontal Assessment Battery (FAB). Data were analyzed using generalized estimating equations and Bonferroni-adjusted post-hoc tests. RESULTS: Sixty-three participants were randomized (memantine, n&#xa0;=&#xa0;31; placebo, n&#xa0;=&#xa0;32), and all completed follow-up. Groups were comparable at baseline for demographic and clinical variables and for most cognitive measures. Both groups improved over time (P&#xa0;<&#xa0;0.001), but improvement was greater with memantine for global cognition at week 6 (MD&#xa0;=&#xa0;9.32; 95% CI, 4.84-13.81; P&#xa0;<&#xa0;0.001) and week 18 (MD&#xa0;=&#xa0;12.69; 95% CI, 8.67-16.71; P&#xa0;<&#xa0;0.001). FAB total scores favored memantine at week 18 (MD&#xa0;=&#xa0;2.68; 95% CI, 1.76-3.61; P&#xa0;<&#xa0;0.001), but not at week 6. Domain analyses showed significant benefits for NuCog attention, visuoconstructional ability, memory, and executive function, and for several FAB subscales by week 18. CONCLUSIONS: Adjunctive memantine improved global cognition and, over longer follow-up, executive function in BD. These findings support NMDA receptor modulation as a potential strategy for cognitive dysfunction in BD.

Comparison of summative assessments between simulated electronic health records versus traditional paper-based patient cases: A non-inferiority randomized controlled trial.

INTRODUCTION: Electronic health records are fundamental to contemporary pharmacy practice, yet evidence supporting their use in pharmacy education is lacking. This single-center, non-inferiority randomized controlled trial with blinded outcome assessment evaluated whether delivering patient cases via a simulated academic EHR (aEHR) was non-inferior to a traditional paper-based format in student exam performance. METHODS: 53 third-year PharmD students at the University of British Columbia were randomized 1:1 to complete a mock summative examination using either the aEHR or paper-based case delivery, stratified by self-reported EHR comfort level. The primary outcome was mean written exam score (%). Non-inferiority was pre-specified at a margin of 14%. Adjusted linear regression was used for the primary analysis, with a multiple imputation sensitivity analysis. Student perceptions were explored through post-exam focus groups analyzed using inductive thematic analysis. RESULTS: 42 students (21 per group) completed the exam and were included in the primary analysis. Mean scores were 66% (SD 11) in the aEHR group and 68% (SD 10) in the paper group. The adjusted mean difference (paper minus aEHR) was -2.2% (95% CI -9.2% to +4.8%), satisfying non-inferiority but not superiority. Sensitivity analysis (n&#xa0;=&#xa0;53) yielded consistent results (-2.3%; 95% CI -7.1% to +4.1%). Focus groups revealed initial student anxiety with the aEHR but recognized its alignment with clinical practice. DISCUSSION: These findings support the feasibility of integrating simulated EHRs into summative pharmacy assessments without compromising performance. CONCLUSION: Simulated EHRs are a non-inferior assessment medium compared with paper-based formats and represent a viable step toward technology-driven pharmacy practice environments.

Chemotherapy-Induced Nausea and Vomiting in Early Breast Cancer Patients Receiving Adjuvant Chemotherapy With Fluorouracil, Epirubicin, Cyclophosphamide Followed by Docetaxel Versus an Anthracycline-Free Regimen With Docetaxel, Cyclophosphamide-Results From a Randomized Clinical Trial.

Chemotherapy-induced nausea and vomiting (CINV) remains an important side effect despite new antiemetic drugs. This study tried to understand the occurrence of CINV in patients receiving two different chemotherapy regimens. As part of the randomized controlled clinical trial SUCCESS C (NCT00847444), 1582 of the 3463 patients completed CINV diaries. Patients were randomized to receive either chemotherapy with FEC (5-fluorouracil, epirubicin, cyclophosphamide followed by docetaxel) or TC (docetaxel, cyclophosphamide). CINV was evaluated hourly using a specially designed questionnaire. Endpoints of the study were complete response (no emesis) and total control (no nausea and no emesis) and were assessed with Kaplan-Meier curves and Cox regression analyses over three chemotherapy cycles. Eight hundred fourteen patients received FEC and 768 received TC; patients and tumor characteristics were similar in both groups. Patients receiving FEC had significantly more nausea and vomiting, with the main difference in the first 12&#x2009;h. In the first cycle, the 0-12-h nausea/emesis-free rates were 70%/41% for FEC and 91/76% for TC. By 24&#x2009;h after chemotherapy, the rates were 65%/33% (FEC) and 85%/60% (TC). The differences were similar in cycles 2 and 3. The detailed analysis of CINV in the study is unique and paves the way for modern CINV analysis of new therapeutics such as antibody-drug conjugates.

Safety and outcomes of dapagliflozin initiation in critically ill patients with acute kidney injury: A post-hoc analysis of the defender trial.

BACKGROUND: SGLT2 inhibitor use in acute kidney injury (AKI) is controversial due to concerns about hemodynamic instability. We evaluated dapagliflozin initiation in critically ill patients with AKI enrolled in the DEFENDER trial. METHODS: Among 212 patients with AKI at enrollment (100 dapagliflozin, 112 control), we compared 28-day mortality, kidney replacement therapy (KRT), and composite death/KRT. Adjusted risk differences were estimated controlling for age, sepsis, baseline vasopressor use, and creatinine. Physiological trajectories (creatinine, urine output, fluid balance, acid-base parameters) over days 1-5 were analyzed using mixed models. Likelihood ratios quantified compatibility with clinically meaningful harm or benefit. RESULTS: Event rates were similar: 28-day mortality 38% vs 40%, KRT 12% vs 18%, composite 41% vs 42% (dapagliflozin vs control). Adjusted risk differences were&#xa0;-&#xa0;1.9% (95% CI -14.5 to 10.7) for death, -7.4% (-16.2 to 1.5) for KRT, and&#xa0;-&#xa0;0.9% (-13.6 to 11.8) for the composite. Physiological trajectories showed no divergence suggestive of hemodynamic or metabolic instability. Likelihood ratios provided limited separation: at 5% absolute effect threshold, LR against harm was 1.47 and against benefit 1.19. CONCLUSIONS: Dapagliflozin initiation in critically ill patients with AKI was not associated with excess mortality, KRT, or physiological derangement. The near-neutral evidential profile indicates neither moderate harm nor benefit can be excluded, supporting feasibility of dedicated trials of SGLT2 inhibitors in AKI.

Randomised, Multicentre Clinical Trial Found That Hypertonic Saline Did Not Reduce the Length of Stay of Hospitalised Patients With Acute Bronchiolitis.

AIM: Bronchiolitis is a major cause of hospitalisation in young children, but the effectiveness of inhaled hypertonic saline remains unclear. We compared treating hospitalised infants with nebulised hypertonic saline or normal saline. METHOD: This multisite, double-blind RCT was conducted from 1 October 2023 to 1 April 2025 in four Polish paediatric units. Children from 5&#x2009;weeks to 24&#x2009;months, who had been hospitalised with mild-to-moderate bronchiolitis, were randomly assigned to receive nebulised 3% hypertonic saline or 0.9% normal saline until discharge. They were followed for 7&#x2009;days. RESULTS: The study comprised 181 children (55% male) with a mean age of 8.3&#x2009;&#xb1;&#x2009;6.3&#x2009;months: 90 were randomised to hypertonic saline and 91 to normal saline. The median hospital stay was 2.68 (1.92-4.03) days in the hypertonic saline group and 2.79 (1.8-3.96) days in the normal saline group. The mean difference was -0.11&#x2009;days (95% confidence interval -0.73 to 0.12, p&#x2009;=&#x2009;0.3). No differences were observed in clinical severity scores between the groups. Readmissions only occurred in the normal saline group (5.9%). CONCLUSION: Hypertonic saline inhalation did not reduce the length of hospital stay or improve clinical severity scores in hospitalised children with bronchiolitis, but it was associated with a lower risk of rehospitalisation.

Short-term psychodynamic psychotherapy for functional neurological disorder: A pilot randomized controlled trial.

BACKGROUND: Evidence-based psychotherapeutic treatments for Functional Neurological Disorder (FND) remain limited. This pilot trial evaluated the preliminary efficacy of Short-term Psychodynamic Psychotherapy (STPP) plus Standard Medical Care (SMC) compared with SMC alone in reducing FND symptom frequency. METHODS: Adults with FND were randomized (1:1) to receive either SMC alone or 12 weekly sessions of STPP plus SMC. The primary outcome was symptom frequency (days with symptoms in the last 4 weeks) assessed at the end of treatment (3 months) and at 6-month follow-up. Secondary outcomes included treatment response (&#x2265;50% reduction in symptom frequency) and scores on the Hamilton Depression Rating Scale (HAM-D), Hamilton Anxiety Rating Scale (HAM-A), and World Health Organization Disability Assessment Schedule 2.0 (WHODAS 2.0). RESULTS: Of 91 randomized patients (mean age 38.2 years, 75.8% female), 81.3% completed follow-up. Intention-to-treat analysis using Linear Mixed Models showed that STPP plus SMC significantly reduced symptom frequency compared with SMC alone (estimated mean difference -5.72 [95% CI -8.68 to -2.77]; Cohen's d = 0.77; p&#x202f;<&#x202f;0.001).Treatment response was achieved by 65.8% in the intervention group versus 16.7% in controls (OR 8.21 [95% CI 2.79-24.19]; p&#x202f;<&#x202f;0.001; NNT 2.0).Significant improvements were also observed for depression (HAM-D: estimated mean difference -10.80; d = 1.45), anxiety (HAM-A: -7.94; d = 1.06), and disability (WHODAS 2.0: -5.77; d = 0.74), all p&#x202f;<&#x202f;0.001. CONCLUSIONS: STPP was associated with clinically meaningful improvements in FND symptom frequency and all secondary outcomes, with large effect sizes and high treatment response rates. These findings support the preliminary efficacy of STPP for FND and justify larger, multicenter confirmatory trials.

Blinding integrity in psychedelic research: Evidence from a comparative randomized controlled trial of psilocybin, MDMA, and methylphenidate in healthy volunteers.

Maintaining effective blinding is a major methodological challenge in psychedelic research. This study provides a comprehensive evaluation of blinding integrity in 120 healthy volunteers who received either psilocybin, MDMA, or methylphenidate (active placebo) in a double-blind, randomized controlled trial. Using a multi-level assessment incorporating forced-choice substance guesses, certainty ratings, decision factors, and subjective substance effects, the analyses characterize blinding integrity and its relation to the substance experience. Results indicate that overall blinding was insufficient, with psilocybin showing the highest rates of functional unblinding, MDMA moderate levels, and methylphenidate the lowest. As an active placebo, methylphenidate provided more effective blinding for MDMA than for psilocybin. Incorporating certainty levels of substance guesses revealed a more differentiated pattern, with lower functional unblinding rates. Decision factors and subjective substance experiences were associated with phenomenological substance effects. Prior substance experiences did not influence accuracy of forced-choice substance guesses. These findings provide empirical guidance for the design and reporting of blinding procedures in psychedelic trials and underscore the value of systematic, multi-level assessment of blinding integrity.

Adherence and efficacy of the 0&#x2009;-&#x2009;7&#x2009;-&#x2009;21-day versus the 0&#x2009;-&#x2009;1&#x2009;-&#x2009;6-month hepatitis B vaccination schedules among people who use drugs: a two-year randomized controlled trial.

BACKGROUND: To compare the adherence and efficacy between the 0&#x2009;-&#x2009;7&#x2009;-&#x2009;21-day and the 0&#x2009;-&#x2009;1&#x2009;-&#x2009;6-month hepatitis B virus (HBV) vaccination schedules among people who use drugs (PWUD) in China. RESEARCH DESIGN AND METHODS: A randomized controlled trial was conducted in 1261 HBV-susceptible PWUD from compulsory isolated detoxification centers (CIDCs) and methadone maintenance treatment (MMT) clinics in Xi'an. A 20&#x2009;&#xb5;g per-dose vaccine was used. HBV surface antibody (anti-HBs), surface antigen, and core antibody were tested at months 7, 15, and 22 after the first dose. RESULTS: Third-dose coverage was significantly higher in the 0&#x2009;-&#x2009;7&#x2009;-&#x2009;21-day group (74.40%) than in the 0&#x2009;-&#x2009;1&#x2009;-&#x2009;6-month group (51.58%, p&#x2009;<&#x2009;0.001), mainly driven by participants from CIDCs (77.75% vs. 45.69%). Anti-HBs positive rates at months 7, 15, and 22 among participants who completed all three doses were significantly higher for the 0&#x2009;-&#x2009;1&#x2009;-&#x2009;6-month schedule (90.71%, 76.82%, and 67.35%) than for the 0&#x2009;-&#x2009;7&#x2009;-&#x2009;21-day schedule (74.23%, 49.40%, and 40.95%; all p&#x2009;<&#x2009;0.001). HBV infection incidence was similar between schedules, but significantly different between vaccinees and non-vaccinees (p&#x2009;=&#x2009;0.018). CONCLUSIONS: The 0&#x2009;-&#x2009;7&#x2009;-&#x2009;21-day schedule substantially enhances three-dose completion in PWUD, but induces a notably weaker anti-HBs response and persistence. Schedules should be selected based on the management models for PWUD and their individual characteristics. CLINICAL TRIAL REGISTRATION: Chinese Clinical Trial Registry (ChiCTR1900022403).

King's Mill anterior-posterior and transverse versus paracervical block in operative outpatient hysteroscopy: a randomised trial.

BACKGROUND: Pain control during operative outpatient hysteroscopy remains a clinical challenge, with the paracervical block (PCB) showing inconsistent efficacy. The King's Mill Anterior-Posterior and Transverse (KAPT) block targets the Lee-Frankenhauser plexus within the uterosacral ligament complex, where the highest density of uterine and cervical sensory fibres lies. We compared the KAPT block with the PCB in operative outpatient hysteroscopy. METHODS: Single-centre, participant- and outcome assessor-blinded randomised controlled trial in a UK district general hospital. Forty-eight women undergoing operative outpatient hysteroscopy were randomised 1:1 to the KAPT block or the PCB, each delivered with 10&#x2009;ml of prilocaine. Pain was measured on a 10-point Visual Analogue Scale (VAS) during the procedure and 10&#x2009;minutes post-procedure (co-primary endpoints), and during cervical dilatation (exploratory). Analyses used the Mann-Whitney U test on an intention-to-treat basis, with Hodges-Lehmann median differences, percentile bootstrap 95% confidence intervals, and a hierarchical fixed-sequence testing strategy. RESULTS: Median intra-procedural VAS was 1 (IQR 0 to 3) with the KAPT block versus 2 (IQR 1 to 6) with the PCB (Hodges-Lehmann median difference -1.00, 95% CI -3.00 to 0.00; p&#x2009;=&#x2009;0.040). At 10&#x2009;minutes post-procedure, median VAS was 0 (IQR 0 to 1.25) versus 2 (IQR 0 to 3.25) (median difference -1.00, 95% CI -2.00 to 0.00; p&#x2009;=&#x2009;0.011). Both co-primary endpoints reached significance under hierarchical testing. Cervical dilatation pain did not differ significantly (p&#x2009;=&#x2009;0.146). Satisfaction was 100% in both arms; willingness to recommend was 100% (KAPT) versus 95.8% (PCB). No serious adverse events occurred. CONCLUSIONS: The KAPT block was associated with lower intra-procedural and post-procedural pain than the PCB, with effect sizes consistent with a clinically meaningful difference. These findings support the KAPT block as a superior, anatomically targeted alternative to the PCB and justify evaluation in a larger multicentre trial.Trial registration: ISRCTN15619382.

Multimodal Therapy With Metformin, Inositol and Dietary Restriction Improves Insulin Resistance and Endocrine Outcomes in Women With Polyendocrine Metabolic Ovarian Syndrome: A Randomized Controlled Trial.

INTRODUCTION: Polyendocrine metabolic ovarian syndrome (PMOS), formerly known as polycystic ovary syndrome (PCOS), is a common endocrine-metabolic disorder characterized by insulin resistance, hyperandrogenism and ovulatory dysfunction. Metformin, inositol supplementation and lifestyle modification are widely used treatments, but direct comparative evidence remains limited. Multimodal therapy combining metformin, inositol and dietary restriction produces greater metabolic and reproductive improvement than single-modality interventions. METHODS: We conducted a 12-week randomized controlled trial in 192 women aged 18-35 years diagnosed with PMOS according to Rotterdam criteria. Participants were allocated to metformin (1500-2000 mg/day), inositol (myo-inositol 2&#x2009;g plus d-chiro-inositol 50&#x2009;mg twice daily), calorie-restricted diet (1200-1500&#x2009;kcal/day), or combination therapy. Primary outcomes included changes in body mass index (BMI) and insulin resistance assessed by HOMA-IR. Secondary outcomes included testosterone, LH/FSH ratio and menstrual regularity. Analysis was performed using analysis of covariance (ANCOVA), with post-intervention values as dependent variables and corresponding baseline values as covariates. Categorical outcomes were compared using the Chi-square test. RESULTS: All interventions improved metabolic and endocrine parameters. Combination therapy resulted in the greatest reduction in HOMA-IR (-&#x2009;2.64, 95% CI&#x2009;-&#x2009;2.82 to -2.46, p&#x2009;<&#x2009;0.001) and BMI (-&#x2009;2.8&#x2009;kg/m2, 95% CI&#x2009;-&#x2009;3.05 to -2.55, p&#x2009;<&#x2009;0.001). Menstrual cyclicity improved across all groups, with the highest proportion of participants reporting cycle regularisation in the combination therapy group (85.4%), compared with dietary restriction (72.9%), inositol (64.6%), and metformin (39.6%) (p&#x2009;<&#x2009;0.001). Given the short follow-up duration, these findings reflect early improvements rather than sustained normalisation. CONCLUSION: Multimodal therapy was associated with superior metabolic and reproductive outcomes compared with single-modality interventions in women with PMOS.

Effect of intraoperative 40-hz gamma-frequency auditory stimulation on postoperative delirium in older adults undergoing major surgery: a randomized clinical trial protocol.

INTRODUCTION: Postoperative delirium (POD) is a common and clinically significant complication among older adults undergoing major surgery under general anesthesia. Gamma-frequency (40-Hz) auditory stimulation has demonstrated potential neuroprotective and cognition-enhancing effects, suggesting a plausible role in perioperative delirium prevention. However, direct clinical evidence supporting intraoperative 40-Hz auditory stimulation in reducing POD remains limited, warranting rigorous evaluation in a randomized trial. PATIENTS AND METHODS: This prospective, parallel-group, randomized controlled trial will enroll 550 older adults scheduled for major noncardiac, nonneurosurgical surgery under general anesthesia. Participants will be randomized in a 1:1 ratio to either the active stimulation group, receiving intraoperative 40-Hz gamma-frequency auditory stimulation delivered via headphones for 2&#x2009;h following successful anesthesia induction, or the sham stimulation group, wearing headphones without active auditory output. The primary outcome is the incidence of POD on postoperative day 1 though 3, assessed using the Confusion Assessment Method (CAM) or the CAM for the ICU (CAM-ICU). Secondary outcomes include POD severity, sleep quality, pain scores, analgesic consumption, the incidence of postoperative nausea and vomiting (PONV), rescue antiemetic use, duration of post-anesthesia care unit (PACU) stay, length of hospital stay, quality of postoperative recovery, incidence of perioperative adverse events; postoperative morbidity, health-related quality of life, and all-cause 30-day mortality. DISCUSSION: This trial will determine whether intraoperative 40-Hz gamma-frequency auditory stimulation reduces the incidence of POD among older adults undergoing major surgery under general anesthesia. If efficacious, this noninvasive intervention could constitute a feasible perioperative strategy to mitigate delirium risk and enhance postoperative recovery.

Efficacy of smartphone- and bibliotherapy-delivered multicomponent lifestyle medicine interventions for probable depression: A three-arm randomized controlled trial.

BACKGROUND: This study examined the efficacy of smartphone- (AG) and bibliotherapy-delivered (BG) lifestyle medicine (LM) interventions compared with a waitlist control group (WLG) in reducing depressive symptoms. METHODS: A total of 122 adults with probable depression were randomized to AG (n&#xa0;=&#xa0;41), BG (n&#xa0;=&#xa0;40), or WLG (n&#xa0;=&#xa0;41). AG and BG received the same core 8-week multicomponent LM intervention via a smartphone application or booklets, respectively. The core content included lifestyle psychoeducation, physical activity, diet and nutrition, stress and sleep management, goal-setting, and motivational techniques. Outcomes were assessed at baseline and immediate post-intervention (Week 9) in all groups, with 1-month (Week 13) and 3-month (Week 21) follow-ups conducted in the intervention groups only. RESULTS: At Week 9, AG (d&#xa0;=&#xa0;0.89) and BG (d&#xa0;=&#xa0;0.64) showed significantly greater reductions in depressive symptoms than WLG, with within-group improvements maintained at 1- and 3-month follow-ups (ps&#xa0;<.001, d&#xa0;=&#xa0;0.77-0.96). Clinically significant improvement was achieved by 78% of AG and 55% of BG participants, both significantly higher than WLG (19.5%; ps&#xa0;<.001). Compared with WLG, both interventions yielded greater improvements in overall lifestyle and physical activity (d&#xa0;=&#xa0;0.59-0.91) at Week 9. The AG showed additional benefits for perceived stress, health responsibility, nutrition, spiritual growth, and stress management (d&#xa0;=&#xa0;0.58-0.73), whereas BG uniquely improved insomnia symptoms (d&#xa0;=&#xa0;0.83). CONCLUSION: Smartphone- and bibliotherapy-delivered LM interventions are efficacious for managing probable depression. Further RCTs comparing them with established treatments are warranted.

Pulmonary artery catheters or central venous catheters for cardiac surgery: the PUMA Pilot randomised clinical trial.

INTRODUCTION: Pulmonary artery catheters are used widely in cardiac surgery despite observed associations with worse outcomes and guidelines that recommend against their routine use. No adequately powered randomised trials are available. METHODS: The PUMA Pilot was a multicentre, randomised, parallel assignment, open-label, pilot and feasibility trial conducted at three tertiary cardiac surgery centres. Eligible patients were adults undergoing coronary artery bypass grafting, aortic valve replacement or surgery on the aortic root or ascending aorta with or without aortic valve replacement, with a predicted surgical mortality of <&#x2009;2%. Patients were allocated randomly to receive a pulmonary artery catheter or a central venous catheter inserted immediately before surgery. The primary feasibility outcome was protocol compliance, defined as receiving the assigned intervention without crossover. Secondary feasibility outcomes were eligibility rate; recruitment proportion and rate; data completeness; and rate of clinician refusal. RESULTS: We screened 480 patients and 206 (43%) were eligible; 150/203 (74%) approached provided informed consent. Three of 206 (1%) eligible patients were not included due to clinician refusal. Of 149 patients who were randomised, 76 were assigned to the pulmonary artery catheter group and 73 to the central venous catheter group. For the primary feasibility outcome, 147 patients (99%) received the allocated intervention. Data were complete for 144 (97%) patients. Median (IQR [range]) days alive and at home at 30&#x2009;days was 23.7 (21.9-24.7 [7.0-26.0]) in the pulmonary artery catheter group and 22.9 (20.8-23.9 [8.6-25.8]) in the central venous catheter group. Acute kidney injury occurred in 26/76 (34%) patients in the pulmonary artery catheter group and 14/73 (19%) in the central venous catheter group. DISCUSSION: A randomised trial of pulmonary artery catheters compared with central venous catheters in low-risk cardiac surgery is feasible. Such a trial would address significant practice variability and inform international guidelines.

HPV Testing Versus Cytology for Cervical Cancer Screening&#xa0;Among Women 50&#x2009;Years and Older: Evidence From the HPV FOCAL Randomized Controlled Trial.

Evidence on the comparative effectiveness of HPV testing versus cytology specifically in women aged &#x2265;&#x2009;50&#x2009;years who are approaching screening cessation remains limited. This analysis included 6471 women aged &#x2265;&#x2009;50 at baseline screening in the HPV FOCAL randomized clinical trial. Women were randomly allocated to receive cytology (Control Group, n&#x2009;=&#x2009;3248, 50.19%) or HPV testing (Intervention Group, n&#x2009;=&#x2009;3223, 49.81%) at baseline, with co-testing at 48-month exit. We calculated incidence rates and risk ratios for CIN2+ detection over follow-up and compared missed lesions at exit by screening method. At the 48-month exit, CIN2+ detection was lower among HPV baseline-negative women than among those in the cytology group (1.61/1000 [95% CI, 0.52-3.76] vs. 3.15/1000 [95% CI, 1.51-5.78]; risk ratio, 0.51 [95% CI, 0.11-0.91]), reflecting higher baseline detection with HPV testing and fewer prevalent lesions at exit. Even with cytology re-screening at 2&#x2009;years, 50% of CIN2+ cases were missed compared to 30% with HPV testing. After adjusting for age, education, smoking status, and lifetime sexual partners, the hazard ratio for CIN2+ comparing HPV to cytology was 0.44 (95% CI, 0.22-0.88). Among women aged &#x2265;&#x2009;50&#x2009;years, HPV primary screening was more effective than cytology at detecting CIN2+ lesions and was associated with a continued lower subsequent risk following a negative HPV test, supporting its use in cervical cancer screening programs in this age cohort.

Randomized Trial of Intensive Nurse-Led Follow&#x2011;Up Versus Standard Care in Inflammatory Bowel Disease.

BACKGROUND: &#xa0;Nurses play a key role in inflammatory bowel disease (IBD) management. This randomized controlled trial evaluated intensive nurse-led program in patients with IBD starting advanced therapy. METHODS: &#xa0;Patients were randomized (1:1) to intensive nurse follow&#x2011;up (Arm&#xa0;A) or standard care (Arm&#xa0;B). Both arms received baseline nurse education; Arm A additionally had scheduled nurse calls and visits. Primary outcome was reduction in IBD&#x2011;Disk score in W12. Secondary outcomes were W52 reduction, robust response (>&#x2009;20-point improvement), and IBD-Disk remission (score&#x2009;<&#x2009;40). RESULTS: Overall, 98 patients were randomized (Arm&#xa0;A:&#xa0;n&#x2009;=&#x2009;50; Arm&#xa0;B:&#xa0;n&#x2009;=&#x2009;48) with similar baseline characteristics. Mean baseline IBD&#x2011;Disk scores were 49.2&#x2009;&#xb1;&#x2009;20.7 in Arm&#xa0;A and 42.0&#x2009;&#xb1;&#x2009;19.8 in Arm&#xa0;B (p&#x2009;=&#x2009;0.07). At W12, both groups improved, with greater IBD-Disk reductions in Arm A (16.1&#x2009;&#xb1;&#x2009;22.9 vs. 10.1&#x2009;&#xb1;&#x2009;20.1, p&#x2009;=&#x2009;0.09). At W52, improvement was greater in Arm&#xa0;A (18.4&#x2009;&#xb1;&#x2009;20.7 vs 9.4&#x2009;&#xb1;&#x2009;17.8; p&#x2009;=&#x2009;0.08). More patients achieved robust response in Arm A (49% vs 21%, p&#x2009;=&#x2009;0.013) at W12. By W52, IBD-Disk remission was achieved by 22/25 (88%) patients in Arm A vs 18/28 (64%) in Arm B (p&#x2009;=&#x2009;0.045). CONCLUSIONS: &#xa0;In this pilot randomized trial, intensive nurse-led follow-up did not significantly improve IBD-Disk at week 12, yet favorable trends of functional outcomes were observed. Intensive nurse&#x2011;led follow&#x2011;up program may improve quality of life in patients with IBD. These findings support the integration of specialist IBD nurses to improve patient&#x2011;centered outcomes.
