Interactive gaming during inhalational induction of anesthesia reduces pediatric patient anxiety and improves induction compliance: A randomized controlled trial.

BACKGROUND: Preoperative anxiety affects up to 75% of pediatric surgical patients and is associated with adverse postoperative outcomes. Traditional anxiolytic strategies with premedication carry drawbacks including delayed recovery and paradoxical reactions, driving interest in non-pharmacologic alternatives. Audiovisual distraction represents one approach, encompassing passive methods (e.g. watching a video) and active modalities (e.g. interactive gaming). The Bedside Entertainment and Relaxation Theater (BERT) is a projection-based environment that enables audiovisual distraction during induction. Whether BERT-based interactive gaming reduces anxiety and improves induction compliance compared to standard perioperative care remains unknown. METHODS: This single-center RCT enrolled 74 pediatric patients aged 4 to 14 undergoing inhalational induction, randomized to standard care (SOC) or interactive gaming via BERT added to SOC during induction (BERT). The primary outcome was change in patient anxiety from baseline to induction, measured using the Modified Yale Preoperative Anxiety Scale (mYPAS). Secondary outcomes included caregiver anxiety, induction compliance, OR efficiency, opioid administration, and OR staff perceptions. RESULTS: Patients in the BERT group experienced significantly smaller increases in anxiety from baseline to induction than SOC (median mYPAS increase [IQR]: 0 [0 to 0] vs 10 [0 to 38], p < 0.001). Induction compliance improved, with lower Induction Compliance Checklist (ICC) scores indicating fewer induction-related disruptive behaviors than SOC (median: 0 vs 1, shift -1 [95% CI: -2 to 0]; p = 0.004). Caregiver anxiety increased less in the BERT group than SOC (mean STAI increase: 0.18 vs 1.89, difference - 1.7, [95% CI: -3.2 to -0.26]; p = 0.022). OR staff reported high acceptability, with 97% supporting continued use. No differences were observed in OR efficiency or opioid administration between groups. CONCLUSIONS: Interactive gaming via BERT attenuated increases in patient anxiety, improved induction compliance, and reduced the rise in caregiver anxiety without prolonging OR time. These findings support BERT as an effective, workflow-compatible anxiolytic strategy for pediatric inhalational induction.

Intravesical mitomycin-C administered immediately before transurethral resection of bladder tumor in non-muscle-invasive bladder cancer: Clinical outcomes and molecular predictors from over 3 years of extended follow-up in a phase II trial.

PURPOSE: To evaluate the long-term outcomes and molecular correlates of response after immediate preoperative intravesical chemotherapy (IPeIC) with mitomycin-C (MMC) in patients with non-muscle-invasive bladder cancer (NMIBC). MATERIALS AND METHODS: In this single-center, open-label, randomized phase II trial, 33 patients received two split doses of IPeIC/MMC (40 mg/20 mL), whereas 38 patients underwent transurethral resection of bladder tumor (TURBT) alone. The primary endpoint was 3-year recurrence-free survival (RFS), and secondary endpoints included progression-free survival (PFS). Exploratory RNA sequencing was performed on IPeIC-treated patients (three with recurrence, 25 without) using a Monte Carlo-based resampling strategy. RESULTS: The median follow-up durations were comparable between the intervention (60.0 months) and control arms (60.4 months). IPeIC/MMC reduced recurrence risk by 76.8% versus TURBT alone (p=0.024), yielding a 3-year RFS rate of 90.7% versus 78.6%. On multivariable analysis, IPeIC/MMC independently improved RFS (hazard ratio [HR] 0.266, p=0.044). IPeIC was associated with superior PFS, with 3-year and 5-year rates of 100% versus 92.1% and 85.8%, respectively, in the controls (HR 0.078, p=0.014). Exploratory transcriptomics identified low Glutathione S-transferase Mu 1 (GSTM1) expression as the factor most strongly associated with recurrence. CONCLUSIONS: IPeIC/MMC is associated with improved long-term oncological outcomes compared with TURBT alone and represents a safe prophylactic option for patients with NMIBC who are unable to receive standard immediate postoperative intravesical chemotherapy because of safety concerns or practical constraints. The GSTM1 findings are hypothesis-generating and support future biomarker-driven validation studies.

"It was good because they have a relationship with us": A qualitative study on low-threshold buprenorphine treatment at syringe services programs.

INTRODUCTION: Syringe service programs (SSPs) reach people who inject drugs with opioid use disorder (OUD) and are novel "low-threshold" venues to initiate buprenorphine treatment. The study investigated patients' experiences with SSP-initiated buprenorphine treatment, which could aid in improving buprenorphine treatment delivery at SSPs. METHODS: The study included 12 participants who completed qualitative exit interviews after a randomized controlled trial of buprenorphine treatment at SSPs. In the parent study, participants received buprenorphine treatment through an onsite model at an SSP or enhanced referral to a community health center based on the randomization sequence. Most participants started taking buprenorphine at home. Exit interviews included participants from both study arms, and the semi-structured interview guide focused on their experiences with clinicians, experiences initiating buprenorphine, prior experiences with OUD treatment, and perceptions about continuing buprenorphine treatment. Four researchers iteratively read, coded, and discussed each transcript, then they derived recurring themes using thematic analysis. RESULTS: Participants were mostly male, middle-aged, and 50% identified as Latino. Four main themes related to buprenorphine treatment initiation: 1) Onsite treatment facilitated buprenorphine prescription, but some participants also expressed a need for additional support; 2) Precipitated withdrawal complicated participants' buprenorphine initiation in both arms; 3) Participants largely experienced the SSPs as affirming and welcoming; and 4) Developing strong relationships with healthcare providers was critical to successful buprenorphine treatment initiation. CONCLUSIONS: The SSP-based model provided rapid access to buprenorphine prescriptions, but precipitated withdrawal was a common complication. Some participants desired additional support and guidance when they started taking buprenorphine at home. The findings point to a "low-threshold, high-touch" approach where participants receive expedited access to buprenorphine providers at SSPs but also additional support throughout the initiation process to avoid and/or manage precipitated withdrawal. Despite some challenges, SSP-based buprenorphine treatment was highly valued by study participants.

Clinical Outcomes and Genomic Epidemiology of Multidrug-Resistant Methicillin-Resistant Staphylococcus aureus Keratitis.

PURPOSE: To characterize the clinical features, management, antimicrobial resistance patterns, and genomic epidemiology of methicillin-resistant Staphylococcus aureus (MRSA) keratitis at two North American centers. DESIGN: Retrospective interventional case series combined with laboratory investigation PARTICIPANTS: Seventy eyes of 67 patients presenting laboratory-confirmed MRSA keratitis were included METHODS: We performed a multicenter retrospective case series of patients with culture-proven MRSA keratitis treated between 2005 and 2022. Demographic and clinical data were collected. Antimicrobial susceptibility testing was conducted, and multidrug resistance (MDR) was defined as resistance to ≥3 antibiotic classes. A subset of isolates underwent whole-genome sequencing with core genome multilocus sequence typing. Vancomycin susceptibility, heteroresistance screening, and tolerance testing were performed on available isolates. MAIN OUTCOME MEASURES: Antimicrobial susceptibility and multidrug resistance rates, vancomycin phenotypic profiles, MRSA genotypic distribution, and final best-corrected visual acuity RESULTS: Median age was 63.5 years, and 61.4% were female. Ocular surface disease (67.7%) and prior ocular surgery (65.2%) were common. Only 25.4% had significant healthcare exposure in the preceding year. Most isolates (85.7%) were MDR. Fluoroquinolone susceptibility was low (moxifloxacin 19.7%). All isolates were susceptible to vancomycin (MIC₉₀ 2 µg/mL), and no vancomycin-intermediate, heteroresistant, or tolerant phenotypes were identified. Whole genome sequencing (n = 41) demonstrated predominance of clonal complexes 5 (68.3%) and 8 (29.2%). Visual outcomes were poor, with most patients (85.2%) having a final visual acuity worse than 20/60 among those with follow-up. CONCLUSIONS: MRSA keratitis is associated with high rates of multidrug resistance and poor visual outcomes despite guideline-based therapy. Infections were predominantly caused by CC5 MDR strains despite limited recent healthcare exposure. These findings highlight the persistence of highly resistant MRSA lineages in community-associated corneal infection and underscore the need for ongoing antimicrobial surveillance and optimized treatment strategies.

Imaging-based surgical stratification of parasagittal meningiomas involving the superior sagittal sinus: a case analysis of 62 patients.

OBJECTIVE: The objective was to evaluate the Superior Sagittal Sinus Involvement Grading (SSIG) system as an imaging-based surgical stratification framework for parasagittal meningiomas adjacent to the superior sagittal sinus (SSS) and to assess its relationship with established sinus invasion grading, venous sinus patency, and operative strategy. METHODS: In this single-center retrospective cohort study, the authors included 62 consecutive parasagittal meningioma resections performed by a single surgeon. SSIG grade was assigned primarily on contrast-enhanced coronal MRI, with CT/MR venography used when available to evaluate sinus patency and collateral venous drainage. Operative variables, resection strategy, and clinicopathological factors were compared across SSIG and Sindou grades, and postoperative complications were compared between low- and high-involvement SSIG groups. RESULTS: SSIG correlated significantly with Sindou grade (rs = 0.790, τb = 0.702, both p < 0.001), and among patients with available venous imaging, it also correlated with the venous sinus involvement grade (rs = 0.742, τb = 0.665, both p < 0.001). With increasing SSIG grade, operative time, intraoperative blood loss, and intraoperative fluid administration increased (p = 0.012, p = 0.008, and p = 0.007, respectively). Compared with the low-involvement group (SSIG grades 1, 2, and 4a), the high-involvement group (SSIG grades 3, 4b, and 5) was less likely to achieve Simpson grade I resection and more likely to adopt Simpson grades II-III strategies (66.7% vs 13.6%, p < 0.001; OR 12.667). Surgery-related complication rates did not differ significantly between groups. The mean follow-up was 13.3 ± 7.9 months, with no radiographic recurrence or progression at last follow-up. CONCLUSIONS: SSIG characterizes parasagittal meningiomas by integrating sinus invasion, venous patency, falcine extension, and parasagittal convexity involvement on preoperative imaging. This surgically oriented framework may help anticipate operative exposure, sinus handling, and resection strategy. Its predictive value for complications and long-term oncological outcomes requires validation in larger cohorts with longer follow-up.

Evaluating a culturally adapted question prompt list to improve end-of-life communication among indonesian migrant caregivers: A randomized controlled trial with qualitative insights.

OBJECTIVE: Indonesian caregivers serve as essential providers of end-of-life (EOL) care in Taiwan. But often face communication challenges due to language, cultural, and hierarchical barriers. This study evaluated the effectiveness of a culturally adapted Question Prompt List (QPL). METHODS: This study employed a two-arm randomized controlled trial design supplemented with qualitative interviews. The study was conducted in a hospice ward and home care setting within a medical center in Taiwan. A total of sixty Indonesian caregivers were recruited and randomly assigned to either the intervention group (n = 30) or the control group (n = 30). The intervention group received routine end-of-life (EOL) education along with a culturally adapted Question Prompt List (QPL), which consisted of 37 items covering domains including the dying process, emotional support, communication, symptom management, and care decision-making. The control group received routine EOL education. Outcome measures included caregiving preparedness, communication self-efficacy, satisfaction, and question-asking behavior. In addition, semi-structured interviews were conducted with eight participants, and the data were analyzed using thematic content analysis. RESULTS: Analysis of covariance revealed no statistically significant between-group differences in caregiving preparedness (F = 1.58, p = .215 [-0.41, 0.44]) or communication selfefficacy (F = 0.83, p = .366 [-0.44, 0.79]). However, communication satisfaction was significantly higher in the intervention group (F = 4.19, p < .05 [0.04, 0.44]). The number of questions asked was also significantly higher in the intervention group (t = -4.35, p < .001 [-5.41, -1.98]). Thematic analysis of qualitative data identified 4 themes and 14 subthemes, illustrating how the QPL reduced anxiety, clarified care needs, and improved confidence. CONCLUSIONS: A culturally adapted QPL can enhance communication engagement and satisfaction among migrant caregivers. PRACTICE IMPLICATIONS: Integrating culturally tailored QPLs into caregiver education and palliative care practice may promote more inclusive and effective communication.

Evaluating the Effectiveness of an Intimate Partner Violence Training Intervention on Healthcare Providers' Preparedness, Knowledge, and Experiences: A Mixed-Methods Study From Nepal.

Intimate partner violence (IPV) places a considerable burden on health systems globally due to its profound effects on women's health, and women who experience violence often seek care from healthcare providers (HCPs). However, HCPs often lack the preparedness and confidence to respond effectively, resulting in missed opportunities for support and care. This study, conducted in Nepal, evaluated the impact of structured training intervention on HCPs' perceived preparedness, knowledge, and attitudes toward managing IPV and its mental health consequences, including self-harm and suicidal tendencies. The study was nested within a larger cluster randomized trial. A convergent mixed-methods design with a comparison group was conducted among 46 female HCPs in all public hospitals (except one) and 17 primary healthcare centers in Madhesh Province, Nepal. The intervention group (n = 24) received a 10-day intensive IPV and mental health training, while the control group (n = 22) completed 3-day training. Quantitative data were collected using a validated self-administered Physician's Readiness to Manage IPV questionnaire and IPV consequences scale. Paired and independent t-tests were applied to assess changes. Insights from key informant interviews were thematically analyzed to explore participant experiences and perceived impacts. At baseline, over 80% of participants had not received IPV management training. Post-intervention, significant improvements were observed in HCPs perceived preparedness (median change 2.1; 95% confidence interval (CI): 1.1- 2.9), knowledge (median change 2.7; 95% CI: 2.0-3.1), and awareness of IPV consequences (mean difference 1.2; 95% CI: 0.5-2.0), with greater gains in the intervention group. Qualitative findings revealed enhanced confidence in identifying IPV, addressing psychological impacts, and supporting survivors through safety planning and referral. The training significantly improved HCPs' knowledge, preparedness, and confidence to manage IPV and related mental health issues, underscoring the need to scale similar programs to frontline providers, particularly in rural and underserved settings, to strengthen health system's response to IPV.

Randomized Trial of Intensive Nurse-Led Follow‑Up Versus Standard Care in Inflammatory Bowel Disease.

BACKGROUND:  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:  Patients were randomized (1:1) to intensive nurse follow‑up (Arm A) or standard care (Arm B). Both arms received baseline nurse education; Arm A additionally had scheduled nurse calls and visits. Primary outcome was reduction in IBD‑Disk score in W12. Secondary outcomes were W52 reduction, robust response (> 20-point improvement), and IBD-Disk remission (score < 40). RESULTS: Overall, 98 patients were randomized (Arm A: n = 50; Arm B: n = 48) with similar baseline characteristics. Mean baseline IBD‑Disk scores were 49.2 ± 20.7 in Arm A and 42.0 ± 19.8 in Arm B (p = 0.07). At W12, both groups improved, with greater IBD-Disk reductions in Arm A (16.1 ± 22.9 vs. 10.1 ± 20.1, p = 0.09). At W52, improvement was greater in Arm A (18.4 ± 20.7 vs 9.4 ± 17.8; p = 0.08). More patients achieved robust response in Arm A (49% vs 21%, p = 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 = 0.045). CONCLUSIONS:  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‑led follow‑up program may improve quality of life in patients with IBD. These findings support the integration of specialist IBD nurses to improve patient‑centered outcomes.

Gubernacular discontinuity and abnormal distal fixation in cryptorchidism: Challenging the classical concept.

BACKGROUND: The gubernaculum is essential for testicular descent, but its detailed surgical anatomy remains poorly understood. We have previously identified an unrecognized anatomy of the round ligament in female patients with sliding inguinal hernias. OBJECTIVE: This study investigated whether comparable anatomical features exist in the gubernaculum of male cryptorchidism patients, as compared to those identified in female sliding hernias. MATERIALS AND METHODS: We retrospectively analyzed undescended testes located in the inguinal canal that underwent open inguinal orchidopexy between 2016 and 2025. Laparoscopically managed nonpalpable testes and those with suprascrotal testes were excluded. To ensure consistent anatomical evaluation, a standardized surgical protocol supervised by the senior author was applied to all cases. Findings were verified using operative reports and video recordings. After dissecting the processus vaginalis along the internal spermatic fascia (transversalis fascia), the pars infravaginalis gubernaculi were exposed. The relationship between the plica gubernaculi and pars infravaginalis gubernaculi, as well as the site of distal gubernacular fixation, was assessed. RESULTS: A total of 64 undescended testes of 56 patients were included. Video recordings were available for 45 of these 64 testes (70%). A patent processus vaginalis was observed in 60 out of 64 testes (94%), while it was obliterated in two ascending testes and unknown in two. In all 64 testes (100%), the pars infravaginalis gubernaculi was not continuous with the plica gubernaculi, with the transversalis fascia interposed between them. This configuration closely resembled that described previously for sliding inguinal hernias in women. Distal gubernacular fixation was located lateral to the scrotum in 49 testes (77%), at the upper scrotal border in 14 testes (22%), and absent in one testis (1.6%). DISCUSSION: Cryptorchidism is associated with a previously unrecognized discontinuity of the gubernaculi and common abnormal distal gubernacular fixation. These findings challenge the conventional views on gubernacular invagination and suggest that abnormal distal fixation may contribute to failed testicular descent. The study was limited by its single-center, retrospective design, small sample size, and lack of a control group. CONCLUSION: This study identified a previously unrecognized discontinuity of the gubernaculi in cryptorchidism. These findings deepen the understanding of the pathophysiology of testicular descent.

Adherence and efficacy of the 0 - 7 - 21-day versus the 0 - 1 - 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 - 7 - 21-day and the 0 - 1 - 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 µg 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 - 7 - 21-day group (74.40%) than in the 0 - 1 - 6-month group (51.58%, p < 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 - 1 - 6-month schedule (90.71%, 76.82%, and 67.35%) than for the 0 - 7 - 21-day schedule (74.23%, 49.40%, and 40.95%; all p < 0.001). HBV infection incidence was similar between schedules, but significantly different between vaccinees and non-vaccinees (p = 0.018). CONCLUSIONS: The 0 - 7 - 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).

Preoperative intramuscular testosterone and urethrocutaneous fistula formation after primary hypospadias repair.

INTRODUCTION: Preoperative androgen stimulation is widely used before hypospadias repair to increase penile dimensions and optimise surgical conditions. However, its impact on postoperative complications, particularly urethrocutaneous fistula formation, remains controversial. OBJECTIVE: To evaluate the association between preoperative intramuscular testosterone therapy and urethrocutaneous fistula formation in children undergoing primary hypospadias repair. STUDY DESIGN: This was a retrospective comparative analysis of prospectively collected clinical data from 111 boys undergoing primary hypospadias repair at a single tertiary pediatric urology center. Patients were divided into two groups: those who did not receive hormonal therapy (Group 1, n = 55) and those who received intramuscular testosterone enanthate (2 mg/kg administered 5 and 2 weeks before surgery; Group 2, n = 56). Preoperative penile measurements, operative characteristics, and postoperative complications were compared. The primary outcome was urethrocutaneous fistula formation. The mean follow-up duration was 11.9 months (median 7 months). RESULTS: Preoperative testosterone therapy was associated with significant increases in glans diameter and stretched penile length at the time of surgery. The hormone-treated group had a significantly higher proportion of proximal hypospadias (p = 0.001), underwent more complex urethroplasty procedures, and had longer operative times (p = 0.007). Postoperative edema and local inflammatory changes were more frequently observed in the hormone-treated group. Despite these differences, urethrocutaneous fistula occurred in four patients in each group (7.3% vs 7.1%, p = 0.357), with no statistically significant difference between groups. DISCUSSION: Despite greater baseline anatomical severity and operative complexity in the hormone-treated group, preoperative testosterone administration was not associated with an increased risk of urethrocutaneous fistula. These findings suggest that improved tissue bulk and vascularity may offset the potential adverse effects of transient inflammatory changes. CONCLUSION: Selective preoperative intramuscular testosterone therapy was not associated with increased urethrocutaneous fistula risk and may be considered a reasonable adjunct in appropriately selected patients undergoing primary hypospadias repair. CLINICAL/TRANSLATIONAL APPLICABILITY: These findings provide clinical reassurance that preoperative testosterone can be used selectively in patients with smaller penile dimensions or anticipated technical difficulty without increasing fistula risk, thereby supporting shared decision-making in clinical practice.

Intensive glycemic control in adults aged 80 years and older: A randomized trial evaluating diabetes complications and competing mortality.

AIMS: To evaluate whether intensive glycemic control reduces microvascular or macrovascular events compared with conservative glycemic targets in independently ambulatory adults aged 80 years or older with type 2 diabetes. METHODS: We conducted a prospective, randomized, open-label, single-center trial enrolling independently ambulatory adults aged ≥ 80 years with type 2 diabetes. Participants were assigned (1:1) to an intensive glycemic target (HbA1c < 7 %) or a conservative target (HbA1c < 9 %) and followed for 5 years. Primary outcomes were composite microvascular and macrovascular events. Analyses were done by intention to treat. Cause-specific Cox models and Fine-Gray subdistribution hazard models were used to account for all-cause mortality as a competing event. This trial is registered with ClinicalTrials.gov, NCT00850798. FINDINGS: 206 participants were randomly assigned to intensive (n = 102) or conservative (n = 104) treatment. At 5 years, mean HbA1c was lower in the intensive group than in the conservative group (7·42 % vs 8·21 %; p = 0·005). Intensive therapy did not reduce microvascular events (hazard ratio [HR] 1·24, 95 % CI 0·76-2·04) or macrovascular events (HR 1·02, 0·36-2·92). Competing risk analyses showed no reduction in cumulative incidence of vascular outcomes (subdistribution HR approximately 1·0 for both). The cumulative incidence of death exceeded that of vascular events, indicating that many participants died before potential glycemic benefits could be realized. Severe hypoglycemia requiring hospitalization was more frequent with intensive therapy (7 vs 1 event). INTERPRETATION: In adults aged 80 years or older with type 2 diabetes, intensive glycaemic control improved glycaemic levels but did not reduce vascular events and increased the risk of severe hypoglycaemia. High competing mortality substantially limits the potential long-term benefit of intensive treatment, supporting conservative and individualized glycemic targets in very old adults.

Preoperative Carbohydrate Supplementation Reduces Thirst and Improves Patient Satisfaction Before Elective Cesarean Delivery: A Randomized Controlled Trial.

BACKGROUND & AIMS: Prolonged preoperative fasting is a major source of patient discomfort, particularly thirst, before elective cesarean delivery. This study aimed to evaluate whether preoperative carbohydrate (CHO) supplementation could alleviate these discomforts and improve patient satisfaction without compromising safety. METHODS: In this single-center randomized controlled trial, 262 women scheduled for elective cesarean delivery under neuraxial anesthesia were randomly allocated to either the CHO group (Group CHO, n = 131), which received 355 mL of an oral carbohydrate solution on the night before and the morning of surgery, or the control group (Group C, n = 131), which followed conventional fasting. The primary outcome was the thirst Numeric Rating Scale (NRS, 0-10) score measured immediately before surgery. Secondary outcomes included hunger NRS, satisfaction NRS, and maternal and neonatal safety parameters. RESULTS: Baseline characteristics were comparable between groups. Despite a longer preoperative fasting duration in Group CHO (9.25 ± 1.05 vs. 8.74 ± 0.97 h, P < 0.001), this group exhibited significantly lower thirst NRS scores (1.69 ± 0.90 vs. 4.02 ± 0.99, P < 0.001) and hunger NRS scores (1.25 ± 0.94 vs. 2.09 ± 0.82, P < 0.001), as well as higher satisfaction NRS scores (7.70 ± 0.69 vs. 5.69 ± 1.17, P < 0.001). Subgroup analyses confirmed consistent benefits of CHO supplementation across most patient characteristics. Further analyses suggested that the maximum effect on thirst reduction occurred at approximately 9.2 h of solid fasting; however, the interaction between fasting duration and treatment group was not statistically significant (P = 0.187). CONCLUSION: Preoperative carbohydrate supplementation effectively reduces thirst and hunger and improves patient satisfaction before elective cesarean delivery without increasing maternal or neonatal risk. The beneficial effects were consistent across varying fasting durations, with exploratory spline analyses suggested a potential peak effect around 9.2 h, though this was not statistically significant and should be interpreted cautiously. These findings support the incorporation of carbohydrate loading into enhanced recovery protocols. TRIAL REGISTRATION: China Clinical Trial Registry ChiCTR2500097956.

Superficial Cervical Plexus Block and Quality of Recovery after Thyroidectomy: A Randomized Clinical Trial.

BACKGROUND: Whether adding a bilateral superficial cervical plexus block to a thyroidectomy enhanced recovery pathway improves postoperative quality of recovery remains uncertain. METHODS: In a single-center prospective, randomized, double-blind, placebo-controlled trial in adults undergoing thyroidectomy with general anesthesia, participants were randomized to bilateral superficial cervical plexus blocks with 0.25% bupivacaine or saline. All participants received multimodal analgesia with dexamethasone, acetaminophen, nonsteroidal anti-inflammatory drugs, and incisional local anesthetic. The primary outcome was quality of recovery, measured by the QoR-40 survey, on postoperative day 1. Secondary outcomes included the need for rescue opioid, total opioid consumption, nausea, vomiting, antiemetic administration, length of stay in the postanesthesia care unit (PACU), and opioid use on postoperative day 1. RESULTS: A total of 160 participants were randomized to receive a superficial cervical plexus block with bupivacaine 0.25% (n = 78) or saline (n = 82). On postoperative day 1, mean QoR-40 scores were 174 (95% CI, 170 to 178) for bupivacaine and 173 (95% CI, 169 to 177) for saline. The adjusted mean difference between bupivacaine versus saline was 0.91 (95% CI, -3.57 to 5.40; P = 0.688). There were no significant between-group differences in the need for opioids in the PACU or on postoperative day 1, nausea, vomiting, or PACU length of stay. However, the total amount of opioid administered in the PACU was lower in the bupivacaine group (median [interquartile range], 0 [0 to 8]) compared with the saline group (2 [0 to 20]; Hodges-Lehmann location shift, 0 morphine milligram equivalents; 95% CI, -4 to 0; P = 0.017), and fewer participants in the bupivacaine group received rescue antiemetics (3 [3.8%] vs . 13 [16%]; difference, -12%; 95% CI, -22% to -1.8%; P = 0.011). CONCLUSIONS: Bilateral superficial cervical plexus blocks did not improve quality of recovery after thyroidectomy when added to a multimodal analgesic regimen including dexamethasone, acetaminophen, nonsteroidal anti-inflammatory drugs, and incisional local anesthetic but were associated with lower total PACU opioid consumption.

Effects of low-dose esketamine on early quality of recovery following minimally invasive esophagectomy: a multicenter, randomized controlled study.

BACKGROUND: Patients undergoing minimally invasive esophagectomy (MIE) frequently experience moderate-to-severe postoperative pain and anxiety-depressive symptoms, compromising postoperative quality of recovery (QoR). Esketamine is a promising adjunct for analgesia and anxiolysis; however, the effect of low-dose esketamine on patient-centered recovery outcomes in MIE remains unclear. METHODS: In this double-blinded, multicenter randomized controlled trial, patients scheduled for elective McKeown esophagectomy were allocated to esketamine (0.25 mg/kg loading dose and 0.125 mg/kg/h continuous infusion during surgery) or placebo (equivalent volume and rate of saline). The primary outcome was the QoR-15 score on postoperative day (POD) 2. Secondary outcomes included QoR-15 scores on POD 1, 3, 7 and 30. Hospital Anxiety and Depression Scale - Anxiety Subscale (HADS-A) and Depression Subscale (HADS-D) scores, numeric rating scale (NRS) pain scores, and the Brief Pain Inventory (BPI) scores on POD 1 to 3, and safety evaluations. RESULTS: A total of 198 patients were analyzed (esketamine, n = 98; placebo, n = 100). Intraoperative esketamine significantly improved QoR-15 scores on POD 2 (116.9 ± 9.4 vs. 110.2 ± 9.8, p < 0.001) and POD 3 (123.6 ± 7.2 vs. 116.8 ± 8.4, p < 0.001) compared with placebo. HADS-A and HADS-D scores were lower in the esketamine group on POD 1 to 3 (all p < 0.001). Additionally, esketamine recipients reported significantly lower NRS scores at rest and during movement and BPI scores for pain severity and pain interference items (all p < 0.001). There were no significant between-group differences in safety outcomes. CONCLUSIONS: Intraoperative low-dose esketamine improved early, patient-reported recovery after MIE by enhancing analgesia and reducing postoperative anxiety and depression without increasing adverse events.

Comparison of analgesic efficacy of pericapsular group of nerve block versus anterior quadratus lumborum block in adult patients undergoing unilateral hip arthroplasty: A comparative randomized controlled trial.

BACKGROUND: Total hip arthroplasty is a painful surgical procedure; therefore, it is a challenge to manage effective pain control during the perioperative period. STUDY OBJECTIVES: We compared the analgesic efficacy of the pericapsular nerve group block and the anterior quadratus lumborum block in patients undergoing unilateral hip arthroplasty. DESIGN: Randomized controlled trial. SETTINGS: Operating room of a tertiary care center. PATIENTS: 92 adult patients of >18 years who underwent elective, unilateral total hip arthroplasty under spinal anesthesia were randomized to either Group P (USG guided PENG block with 30 ml 0.25% ropivacaine +4 mg dexamethasone) or Group Q (USG guided QL block with 30 ml 0.25% ropivacaine +4 mg dexamethasone) 20 min before surgery. MEASUREMENTS: We compared the total perioperative fentanyl consumption between the two groups in the first 24 h as the primary outcome. Other outcomes included time to first rescue analgesia in the postoperative period, NRS scores at rest and on movement at 0, 2, 4, 6, 12, and 24 h, incidence of intraoperative hemodynamic changes, and incidence of postoperative PONV. MAIN RESULTS: There was no significant difference in the total fentanyl consumption between the two groups: 237.5 (150-450) μg in the P group and 250 (125-400) μg in the Q group; p = 0.617. The time to first rescue analgesia was similar in both groups: the P group (198 [123-268] minutes) and the Q group (241 [180-318] minutes); p = 0.120. There was also no difference in pain scores, intraoperative hemodynamic changes, or PONV. CONCLUSION: There was no difference in the perioperative opioid consumption, pain scores, and adverse event rates between the pericapsular nerve group block and anterior quadratus lumborum block in adult patients undergoing unilateral hip arthroplasty.

Ketamine assisted psychotherapy to reduce chronic neuropathic pain: A mixed-methods randomized pilot trial.

BACKGROUND: Intravenous ketamine can provide short-term analgesia in chronic neuropathic pain but benefits often wane after treatment. We conducted a randomized pilot trial to assess the feasibility of combining ketamine infusions with psychotherapy to inform future efficacy trials. METHODS: In this single-center, randomized, outcome-assessor-blinded pilot trial at a Canadian tertiary pain clinic, adults with moderate-to-severe chronic neuropathic pain were randomly assigned in 1:1:1 ratio to the ketamine, psychotherapy, or combined ketamine plus psychotherapy arm. Ketamine was delivered as three intravenous infusions over 16 weeks; psychotherapy consisted of 16 weekly cognitive behavioral therapy and mindfulness-based meditation sessions. The primary outcome was feasibility, assessed using prespecified progression criteria. Exploratory outcomes included changes in pain interference (PROMIS 6a T-score), pain intensity, mood, and qualitative interview findings at week 20 (ClinicalTrials.gov: NCT05639322). FINDINGS: Between October 23, 2023, and March 31, 2025, 30 participants were randomized, and 26 (87%) completed 20-week follow-up. Most feasibility criteria, including consent, retention, data completeness, and absence of study-related serious adverse events, were met; adherence targets were partially met. Exploratory pain outcomes showed numerical improvement across groups, with clinically meaningful reductions observed for pain interference and pain intensity. Sixty-four adverse events were recorded, mostly mild and in ketamine-containing groups; no serious study-related adverse events occurred. CONCLUSIONS: Combined ketamine and psychotherapy was feasible and acceptably safe in this pilot trial, supporting evaluation in a larger efficacy-powered study. FUNDING: The study was funded by the St. Michael's Hospital Innovation Fund, The Canadian Pain Society Early Investigator Award and the Physician Services Incorporation Early Career Researcher Award.

Use of indocyanine green fluorescence versus patent blue V dye for sentinel lymph node biopsy in early breast cancer, a randomized controlled trial.

BACKGROUND: Sentinel lymph node biopsy (SLNB) is standard for axillary staging in early breast cancer. While the combination of radioisotope and blue dye (e.g., patent blue V, PBV) remains the standard, it has limitations including logistics, variable identification rate (IR), and allergic potential. Indocyanine green (ICG) fluorescence is a promising alternative, but high-quality comparative evidence is needed. METHODS: This was a single-center, prospective, randomized controlled trial. Forty patients with early-stage, node-negative breast cancer were allocated to SLNB using either ICG (n = 20) or PBV (n = 20). All patients subsequently underwent completion level I-II axillary lymph node dissection (ALND) as the pathological reference standard for diagnostic performance assessment. Primary outcome was sentinel lymph node (SLN) IR. Secondary outcomes included detection time, number of SLNs retrieved, false-negative rate (FNR), and safety. RESULTS: Baseline characteristics were comparable between groups. The SLN IR was significantly higher with ICG (100% [20/20]) than with PBV (75% [15/20], p = 0.047). ICG was associated with a significantly shorter median detection time (14.5 vs. 24.0 min, p < 0.001) and retrieved more SLNs (mean: 3.6 vs. 2.4, p = 0.002). Most critically, ICG demonstrated 100% sensitivity, specificity, negative predictive value (NPV), and overall diagnostic accuracy, with a 0% FNR. In contrast, PBV achieved a sensitivity of 75%, an overall diagnostic accuracy of 90%, and an FNR of 25%. No ICG-related adverse events occurred. PBV caused skin discoloration in 75% of patients and one (5%) allergic reaction. CONCLUSION: ICG fluorescence achieved a higher SLN IR, shorter detection time, higher sensitivity, lower FNR, and fewer tracer-related adverse events than PBV as a single tracer for SLNB in patients with early-stage breast cancer. These findings suggest that ICG is a promising standalone tracer when radioisotope mapping is unavailable. Larger multicenter studies are required before widespread adoption can be recommended.
