Novel Proactive Speech-Language Intervention Is More Effective Than Usual Care: Randomized Controlled Trial of Babble Boot Camp for Infants With Classic Galactosemia.

PURPOSE: Speech and language disorders cannot be diagnosed and treated until children are approximately 2-4 years old. To investigate whether these disorders can be prevented, we developed and trialed Babble Boot Camp (BBC), the first proactive sustained intervention starting with precursor skills including cooing and babbling. METHOD: Participants were two randomly assigned groups of 22 infants with classic galactosemia, a metabolic disease with known risks for severe speech and language disorders. One group started BBC at under 6 months of age, and the other started at 15 months of age, both completing BBC at 24 months of age. Coached by a speech-language pathologist in weekly telehealth sessions, caregivers implemented BBC activities and routines daily at home. A typical control group and a group of children with classic galactosemia who received usual care participated as well. All children completed standardized assessments of speech and language at postintervention. RESULTS: Assessment scores showed that BBC was more effective than usual care for both intervention groups. Greatest benefits were seen in the group that started at or before 6 months of age, with a proportion of clinically concerning scores equal to that in the typically developing peers. No effects of sex, genotype, or milk consumption were evident in the outcomes. CONCLUSIONS: Findings motivate a paradigm shift from deficit-based to proactive approaches for infants with classic galactosemia. BBC is extensible to many other disorders, with trials currently underway for infants with Down syndrome and infants born preterm.

Effect of transcutaneous auricular vagus nerve stimulation on postoperative pain in patients undergoing thoracoscopic partial lung resection: a randomized, double-blind, controlled clinical trial.

BACKGROUND: Postoperative pain after thoracic surgery remains common and challenging. Transcutaneous auricular vagus nerve stimulation (taVNS) is a noninvasive neuromodulation technique with potential analgesic effects. This study aimed to evaluate the efficacy and safety of taVNS for postoperative pain management in patients undergoing thoracoscopic partial lung resection. METHODS: Adults undergoing thoracoscopic partial lung resection were randomized to active or sham taVNS. The primary outcome was cough pain intensity at 48h post-surgery, assessed by Numeric Rating Scale (NRS). Secondary outcomes included cough pain at 24h and 72h, resting pain, moderate-to-severe pain incidence,&#xa0;opioid consumption, quality of recovery, postoperative pulmonary complications , chest tube duration, hospital stay, postoperative nausea/vomiting, and adverse events. RESULTS: Among 119 analyzed patients (active n&#x2009;=&#x2009;60, sham n&#x2009;=&#x2009;59), active taVNS reduced cough pain scores at 24h, 48h, and 72h postoperatively, as well as resting pain (p < 0.05). It also lowered the incidence of moderate-to-severe cough pain at 24h and 48h, reduced cumulative postoperative opioid use at 24h and 72h, and decreased rescue analgesia on postoperative day 3 (p < 0.05). Active taVNS was associated with a lower incidence of postoperative pneumothorax (p < 0.05). No serious adverse events occurred. CONCLUSION: Perioperative taVNS was associated with a modest analgesic benefit and reduced postoperative opioid requirements after thoracoscopic partial lung resection. The observed reduction in postoperative pneumothorax requires cautious interpretation, and further multicenter trials are needed to determine its clinical utility.

Aquablation/AquaBeam Waterjet Therapy for Benign Prostatic Hyperplasia: Three-Year Functional and Ejaculatory Outcomes in a Multicenter Real-World Italian Cohort.

OBJECTIVE: To evaluate the 3-year functional outcomes of Aquablation/AquaBeam waterjet therapy for bladder outlet obstruction secondary to benign prostatic hyperplasia (BPH), with particular attention to urinary symptoms, quality of life, continence, ejaculatory function, and complications. METHODS: We performed a retrospective analysis of a prospectively maintained multicenter database including 218 consecutive men who underwent Aquablation/AquaBeam for symptomatic BPH between January 2019 and January 2022 at three referral centers. Functional outcomes assessed preoperatively and during follow-up included International Prostate Symptom Score (IPSS), IPSS quality-of-life item (IPSS-QoL), maximum urinary flow rate (Qmax), post-void residual urine (PVR), continence, and ejaculatory function. Median follow-up was 36&#x2009;months. Ejaculatory preservation was evaluated only in patients with preserved antegrade ejaculation at baseline. RESULTS: Median age was 61&#x2009;years (IQR 57-66), median prostate-specific antigen (PSA) was 2.52&#x2009;ng/mL (IQR 0.40-21.60), and median prostate volume was 55&#x2009;mL (IQR 40-73). Median operative time was 56&#x2009;min, while median catheterization time and length of hospital stay were both 48&#x2009;h. Functional improvements were evident from the 3-month follow-up and remained stable through 36&#x2009;months. At 36&#x2009;months, median IPSS improved to 5 and median Qmax to 18&#x2009;mL/s. Median PSA changed modestly from 2.52&#x2009;ng/mL at baseline to 2.75&#x2009;ng/mL at 36&#x2009;months. No cases of de novo urinary incontinence were observed throughout follow-up. Among patients with preserved antegrade ejaculation at baseline, 87% maintained antegrade ejaculation at 36&#x2009;months. Most postoperative complications were minor (Clavien-Dindo grade I-II, 20.2%). One grade III rectal injury occurred (0.5%). Median hemoglobin decreased from 15.2&#x2009;g/dL preoperatively to 14.0&#x2009;g/dL before hospital discharge, and two patients required blood transfusion. During the 36-month follow-up, no surgical retreatment was required, whereas 11 patients (5.0%) received temporary medical retreatment. CONCLUSION: In this multicenter real-world cohort, Aquablation/AquaBeam was safe and effective over 3&#x2009;years, providing durable improvement in lower urinary tract symptoms and quality of life while preserving continence and antegrade ejaculation in most patients. These findings support Aquablation/AquaBeam as a valuable minimally invasive surgical option for selected men with BPH, particularly those who prioritize preservation of ejaculatory function. Longer-term and comparative studies are warranted. TRIAL REGISTRATION: 48281.

Depressive Symptoms and Smoking Cessation Among Adolescents and Young Adults Who Smoke: A Prospective Cohort Study.

PURPOSE: This study examined the bidirectional prospective associations between depressive symptoms and smoking cessation among adolescent and young adults who smoke. METHODS: Data on 1,151 participants aged &#x2264;25 years who smoke and receive peer-led quitline counseling in Hong Kong (2016-2022) were analyzed. Exposures included baseline depressive symptoms and smoking cessation (self-reported 7-day abstinence) at 1, 3, and 6 months; Outcome measures included smoking cessation at 1, 3, and 6 months and depressive symptoms at 6 months. Depressive symptoms were assessed using the Center for Epidemiologic Studies Depression Scale, with a score &#x2265;16 indicating at risk for depression. RESULTS: More severe baseline depressive symptoms were associated with lower odds of smoking cessation at 1, 3, and 6 months, which reversely was associated with lower depressive symptoms at 6 months (all p < .05). Similarly, being at risk for depression at baseline was associated with lower odds of smoking cessation at 1 (adjusted odds ratio [aOR] .66, 95% confidential interval [CI] .47-.93) and 3 months (aOR .71, 95% CI .52-.97). Conversely, smoking cessation at 1 (aOR .40, 95% CI .23-.69), 3 (aOR .58, 95% CI .37-.92), and 6 months (aOR .44, 95% CI .29-.69) was associated with lower odds of at risk for depression at 6 months. DISCUSSION: More severe depressive symptoms were prospectively associated with lower odds of smoking cessation, while smoking cessation was associated with lower depressive symptoms and risk for depression. Integrated interventions simultaneously addressing psychological needs and smoking are warranted, when delivered in smoking cessation programs or embedded within mental health services for youth who smoke.

Compound muscle action potential amplitudes in newborn screen positive spinal muscular atrophy.

OBJECTIVE: To evaluate the utility of compound muscle action potential (CMAP) amplitudes as biomarkers of disease severity in newborn screening (NBS)-positive infants with spinal muscular atrophy (SMA). METHODS: We conducted a retrospective review of 21 infants identified through SMA NBS (11 with 2 SMN2 copies and 10 with 3 SMN2 copies). Baseline and serial right median, ulnar, and fibular motor nerve CMAP amplitudes (millivolts, mV) were obtained during the study. Functional outcomes were assessed using the Children's Hospital of Philadelphia Infant Test of Neuromuscular Disorders (CHOP-INTEND). RESULTS: At baseline, infants with 2 SMN2 copies demonstrated significantly lower median, ulnar, and fibular CMAP amplitudes compared with infants with 3 SMN2 copies (p&#xa0;<&#xa0;0.05). In contrast, baseline CHOP-INTEND scores did not differ significantly between the two groups. Prior to genetic confirmation, a right median CMAP amplitude&#xa0;&#x2265;3.2&#xa0;mV predicted&#xa0;&#x2265;3 SMN2 copies. Following treatment, right median and fibular CMAP amplitudes demonstrated significant improvement over time, including in analyses accounting for SMN2 copies number. CONCLUSION: CMAP amplitudes obtained from multiple upper- and lower-extremity motor nerves provided objective electrophysiological measures that distinguished infants with two versus three SMN2 copies, despite similar baseline CHOP-INTEND scores. Furthermore, CMAP abnormalities were detectable in some cases before confirmatory genetic testing results became available. Serial CMAP measurements demonstrated significant longitudinal changes following treatment, whereas functional assessments approached ceiling values, supporting the potential value of electrophysiological monitoring in the era of disease-modifying therapies. SIGNIFICANCE: CMAP assessment is a useful adjunct in the evaluation of infants identified through SMA NBS.

Less Invasive Surfactant Administration Using Video Laryngoscope to Decrease Pain in Neonates: A Randomized Controlled Trial.

OBJECTIVES: To assess whether the use of video laryngoscope, when compared to conventional laryngoscope decreases pain (assessed by Faceless Acute Neonatal Pain Scale) in preterm neonates while administering surfactant by LISA. METHODS: Preterm neonates <&#x2009;35 weeks requiring FiO2&#x2009;>&#x2009;0.3 on CPAP pressure of at least 6&#x2009;cm of H2O were administered surfactant by LISA technique either by video laryngoscope (Intervention) or conventional laryngoscope (Control). Faceless Acute Neonatal Pain Scale was used to determine pain 5&#x2009;min before the procedure, immediately, 5&#x2009;min, and 10&#x2009;min after the procedure. The primary outcome was severity of pain; secondary outcomes were time taken to complete the procedure, number of attempts, incidence of IVH, and adverse events during the procedure. RESULTS: In total, 42 neonates of <&#x2009;35 weeks gestation with comparable baseline demographics were randomized into 2 groups. The median (IQR) FANS score immediately post-procedure in the intervention arm was 2 (2-4) versus 2 (1-4) in the control arm, p&#x2009;=&#x2009;0.79. There was no statistical difference in the secondary outcomes studied. CONCLUSION: The two groups had no difference in the pain score. The pain experienced by neonates during the LISA procedure was moderate and of short duration and it did not depend on the type of laryngoscope used. Moderate pain during the procedure can be managed with nonpharmacological measures; thereby, the use of sedatives or analgesics can be avoided, which might be of concern. There was no difference in the number of attempts or in time taken to complete the procedure when performed by neonatologists experienced in using conventional laryngoscopes compared to video laryngoscopes.

Metabolic ketosis attenuates NLRP3 inflammasome activation and is associated with improvements in hepatic steatosis and liver stiffness in MASLD: a pilot randomized controlled trial.

BACKGROUND: Metabolic dysfunction-associated steatotic liver disease (MASLD) is increasingly recognized as a systemic metabolic-inflammatory disorder in which metabolic stress and innate immune activation, particularly through the NLRP3 inflammasome, contribute to disease progression. Metabolic ketosis, characterized by increased levels of circulating ketone bodies, especially &#x3b2;-hydroxybutyrate, has emerged as a promising strategy to modulate substrate utilization, inflammatory signaling, and hepatic injury. However, clinical evidence integrating molecular, metabolic, and hepatic outcomes remains limited. METHODS: In this pilot randomized controlled trial, 20 participants with newly diagnosed MASLD were randomly assigned to either a 3-month intervention with a daily C8-enriched medium-chain fatty acid formulation (m-CAP; meta-Capridin, providing approximately 20 g/day of C8) or a standardized low-carbohydrate dietary protocol. Metabolic indices, inflammatory mediators, adipokines, and hepatic enzymes were assessed. The expression of key inflammasome components (NLRP3, caspase-1, and ASC) was evaluated in peripheral blood mononuclear cells, and hepatic steatosis and liver stiffness were measured via transient elastography. RESULTS: The C8-enriched intervention was associated with increased circulating &#x3b2;-hydroxybutyrate levels, indicating the achievement of nutritional ketosis. Changes over time were observed in metabolic parameters, including fasting serum glucose (p < 0.05), HOMA-IR (p < 0.05), body fat percentage (p < 0.05), and BMI (p < 0.05). Alterations in inflammatory mediators and adipokine-related outcomes were also observed following the intervention. At the molecular level, changes in inflammasome-related markers were detected, including caspase-1 mRNA expression (p < 0.05) and NLRP3 expression at the transcriptional (p < 0.05) and protein levels (p < 0.01), whereas ASC expression remained unchanged. Changes in hepatic steatosis (p < 0.01) and liver stiffness measurements were observed following the intervention. Given the absence of significant Group &#xd7; Time interactions for several secondary outcomes, these findings should be interpreted as exploratory and hypothesis-generating. CONCLUSIONS: Induction of metabolic ketosis was associated with changes in metabolic, inflammatory, and hepatic parameters in patients with MASLD. The observed associations between ketosis, inflammasome-related markers, and noninvasive liver outcomes warrant further investigation of ketosis-based interventions as adjunctive approaches in MASLD. Larger and longer-term clinical trials are needed to confirm these findings and to determine whether short-term changes in liver stiffness reflect sustained alterations in hepatic status rather than structural fibrosis regression.

Esketamine vs. sufentanil for quality of recovery after outpatient gynecological surgery: a randomized clinical trial.

BACKGROUND: Perioperative administration of esketamine has been reported to improve early quality of recovery (QoR). However, data on its effects in outpatient surgery are limited. This study aimed to assess the impact of esketamine on QoR in patients undergoing outpatient gynecological procedures. METHODS: In this investigator-initiated, double-blind, randomized clinical trial, patients aged 18-65&#x2009;years scheduled for outpatient gynecological surgery under sedation were allocated to receive esketamine (0.2&#x2009;mg/kg) or sufentanil (0.1&#x2009;&#x3bc;g/kg) combined with propofol (1.5-3&#x2009;mg/kg). The primary outcome was quality of recovery on postoperative day (POD) 1. Secondary outcomes included quality of recovery on POD2, sedation success rate, length of post-anesthesia care unit (PACU) stay, injection pain, postoperative pain, nausea and vomiting, fatigue, patient and clinician satisfaction, sleep quality, and anxiety and depression. RESULTS: A total of 126 patients were randomized, with 63 assigned to the esketamine group and 63 to the sufentanil group. Of these, 125 patients were included in the final analysis (62 in the esketamine group and 63 in the sufentanil group), as one patient lacked follow-up data. The mean (SD) QoR-15 score on POD1 was 137.9 (14.5) in the esketamine group and 137.8 (10.7) in the sufentanil group, with no significant difference between groups (absolute difference, 0.2; 95% CI, -4.2 to 4.6; p&#x2009;=&#x2009;0.93). For secondary outcomes, the esketamine group had a longer PACU stay (median, 28.0 vs. 23.0&#x2009;min; p&#x2009;<&#x2009;0.001), a lower incidence of severe injection pain (22.6% vs. 50.8%; p&#x2009;=&#x2009;0.002), a higher proportion of patients with pain scores &#x2265; 4 at 30&#x2009;min postoperatively (30.6% vs. 6.3%; p&#x2009;=&#x2009;0.001), and higher fatigue scores (median, 3.0 vs. 2.0; p&#x2009;=&#x2009;0.01). Other secondary outcomes did not differ significantly between groups. CONCLUSION: Among patients undergoing sedation for outpatient gynecological procedures, esketamine did not significantly improve quality of recovery on POD1 compared to sufentanil.

Comparative Evaluation of Virtual Reality versus Standard Nursing Care in Managing Pain and Fear during Lumbar Puncture Procedures: A Randomised Controlled Trial.

BACKGROUND: Meningitis is a serious infectious disease that can cause significant morbidity and long-term neurological problems. Although a lumbar puncture is a necessary diagnostic procedure, it is often accompanied by discomfort, anxiety, and fear, which can severely impact the patient's experience. Although there is few data on its application prior to lumbar puncture in adult patients with meningitis, immersive virtual reality (VR) has become a promising non-pharmacological technique for lowering procedural distress. Thus, among individuals undergoing lumbar punctures, this randomized controlled research assessed how well pre-procedural VR reduced pain, anxiety, and fear while enhancing patient satisfaction. OBJECTIVE: This study aims to evaluate the effectiveness of virtual reality (VR) in reducing pain and fear among adults undergoing lumbar puncture (LP) compared with standard care protocol. METHODS: A randomised clinical trial was conducted from May to October 2025, using a single-blind, true experimental design. A total of 85 patients were randomly assigned to either the VR intervention group ( n = 41) or the control group receiving standard care ( n = 44). Pain levels were assessed using a visual analogue scale. Fear was assessed using the Multidimensional Fear-of-Injection Scale. Data were analysed using SPSS version 26. RESULTS: According to the study, the findings revealed a significant reduction in pain levels among the study group following the VR intervention, with mean pain scores dropping from 7.54 &#xb1; 1.925 to 2.49 &#xb1; 0.675. In contrast, the control group showed increased pain intensity, with mean scores rising from 6.84 &#xb1; 1.842 to 8.36 &#xb1; 1.348. The VR group showed a significant reduction in fear scores across all domains, whereas no significant changes were observed in the control group. Direct fear decreased from 20.12 &#xb1; 1.71 to 9.44 &#xb1; 2.00, indirect fear from 17.24 &#xb1; 1.46 to 8.66 &#xb1; 2.24, physiological response improved from 0.34 &#xb1; 0.66 to 3.00 &#xb1; 1.00 and avoidance behaviour decreased from 16.71 &#xb1; 1.49 to 7.80 &#xb1; 1.85. CONCLUSIONS: The research shows that the use of VR prior to LP significantly reduces level of pain and fear compared to standard care. These results support VR as a non-pharmacological intervention for fear and pain to improve patient experience during invasive procedures. In contrast, the control group experienced no improvement.Trial Registration: The IRCT code for the trial was IRCT ID 20250803066743N1.

Fractional laser therapy versus microneedling for non-acne scars and scar-like dermal fibrotic lesions.

BACKGROUND: Scarring caused by trauma, burns, surgery, and other dermal fibrotic conditions can lead to functional limitation and cosmetic distress. The comparative effectiveness of fractional laser therapy and microneedling for non-acne scars remains uncertain. METHODS: We conducted a systematic review and meta-analysis of randomized controlled trials comparing fractional laser therapy with microneedling for non-acne scars and scar-like dermal fibrotic lesions. Following a PROSPERO-registered protocol and PRISMA guidelines, we searched PubMed, EMBASE, Web of Science, Cochrane Library, and CNKI from inception to May 2026 without language restrictions. Parallel-group and split-body randomized trials were eligible. Random-effects models were used to calculate standardized mean differences (SMDs) for continuous outcomes and odds ratios (ORs) for dichotomous outcomes. RESULTS: Nine randomized controlled trials were included. Fractional laser therapy showed a statistically significant advantage over microneedling in scar scores (SMD = -0.99, 95% CI [-1.83, -0.15], P&#x2009;=&#x2009;0.02) and collagen fiber regeneration (SMD = -2.14, 95% CI [-3.57, -0.72], P&#x2009;=&#x2009;0.03). No statistically significant differences were found between the two interventions for elastic fiber improvement, epidermal thickness, or adverse events. Subgroup analyses did not show clear or consistent significant differences according to laser type, including comparisons between traditional and non-traditional fractional lasers and between CO&#x2082; and non-CO&#x2082; fractional laser systems. Substantial heterogeneity was observed across several outcomes, indicating considerable between-study variability. CONCLUSION: Based on currently available randomized evidence, fractional laser therapy may provide superior improvement in overall scar severity and collagen fiber regeneration compared with microneedling for non-acne scars and scar-like dermal fibrotic lesions. However, no clear differences were observed for elastic fiber improvement, epidermal thickness, or adverse-event incidence. Given the substantial heterogeneity, limited sample sizes, and possible reporting bias, these findings should be interpreted cautiously. Further large, standardized trials with longer follow-up are needed.

Transcranial Alternating Current Stimulation at 40 Hz Improves Social Functioning in Children With Autism Spectrum Disorder: A Randomized Clinical Trial.

BACKGROUND: Autism spectrum disorder (ASD) lacks rapid and effective interventions for its core social difficulties. The right temporoparietal junction (rTPJ), a critical hub for social cognition, together with gamma band abnormalities implicated in ASD, provides a promising neuromodulation target. METHODS: In this randomized, double-blind, sham-controlled trial, 47 children with ASD (39 male; mean [SD] age = 8.79 [2.71] years) were assigned to receive either 21 sessions of 40-Hz high-definition transcranial alternating current stimulation (tACS) targeting the rTPJ (3 sessions/day for 7 days) or sham stimulation, with assessments conducted at baseline, postintervention (week 1), and a 3-week follow-up (week 4). The primary outcome was change in Ohio State University Autism Rating Scale-DSM-5 (OARS-5) total scores. Secondary outcomes included the Aberrant Behavior Checklist-Second Edition, Social Responsiveness Scale-Second Edition, and Short Sensory Profile. Eye-tracking metrics during Frith-Happ&#xe9; animations were exploratory measures of theory of mind (ToM)-related social cognitive processing. RESULTS: The active group demonstrated significant improvements in OARS-5 total scores at week 1 (mean difference = -1.13, 95% CI [-1.78 to -0.47], p < .001) and week 4 (mean difference = -1.47, 95% CI [-2.20 to -0.74], p < .001). Improvements in selected behavioral and sensory domains were observed. Average fixation duration during ToM animations showed a significant group &#xd7; time interaction. No serious adverse events occurred. CONCLUSIONS: These findings suggest that 40-Hz tACS targeting the rTPJ may be associated with rapid improvements in ASD symptom severity, particularly social functioning, in children with ASD, while being well tolerated. Clinical significance requires further evaluation.

High-flow nasal cannula oxygenation in sedated endoscopy for high-risk obstructive sleep apnea patients: study protocol for a multicentre randomised controlled trial.

BACKGROUND: Hypoxemia is the most common adverse event during sedated gastrointestinal endoscopy. Patients with high obstructive sleep apnea (OSA) risk (STOP-Bang &#x2265;5) are susceptible due to sedation-induced loss of upper airway tone exacerbating airway collapsibility. Although high-flow nasal cannula (HFNC) benefits general at-risk populations, its efficacy in this specific cohort remains uncertain, as its mild positive pressure falls far below therapeutic continuous positive airway pressure levels for moderate-to-severe OSA, questioning its ability to stent the collapsible airway. Our prior proof-of-concept study in this cohort observed a 5% incidence of hypoxemia with HFNC, confirming feasibility and safety and justifying this confirmatory trial. METHODS: This prospective, multicenter, randomized controlled single-blind trial will enroll 600 adults (STOP-Bang score &#x2265;5) undergoing elective sedated gastroenteroscopy across three centers. Participants will be 1:1 randomized (stratified by center) to HFNC (30&#x2009;L/min pre-oxygenation, 60&#x2009;L/min post-induction) or conventional nasal cannula (6&#x2009;L/min). Both groups receive standardized propofol-alfentanil sedation. The primary outcome is the proportion of patients with at least one episode of hypoxemia (SpO2 75%-90% <60&#x2009;s). Secondary outcomes include the proportion of patients with at least one episode of severe hypoxemia (SpO2 <75% or 75%&#x2264;SpO2<90% &#x2265;60&#x2009;s), the proportion with subclinical respiratory depression (90%&#x2264;SpO2<95%), and the frequency of other adverse events. DISCUSSION: This trial will provide definitive evidence on HFNC's efficacy in high-risk OSA patients, addressing whether it can overcome pressure limitations to prevent hypoxemia. Results are expected to inform sedation management guidelines, establish a new standard of care for this subgroup, and enhance procedural safety. TRIAL REGISTRATION: The trial was registered at the ClinicalTrials.gov on 14 December 2025 (NCT07307560).

Preoperative Proximal Migration of the Radial Head as an Independent Predictor of Suboptimal Outcomes After Osteochondral Autograft Transplantation for Capitellar Osteochondritis Dissecans: A Retrospective Cohort Study.

BACKGROUND: Osteochondral autograft transplantation (OAT) is widely performed for capitellar osteochondritis dissecans (OCD). However, preoperative predictors of suboptimal postoperative outcomes remain unclear. PURPOSE/HYPOTHESIS: The authors aimed to evaluate clinical outcomes after OAT for capitellar OCD and identify preoperative risk factors associated with suboptimal outcomes. They hypothesized that radiographic indicators of disease severity, including preoperative proximal migration of the radial head, lesion size, and lateral wall disruption, would be associated with suboptimal postoperative clinical outcomes. STUDY DESIGN: Cohort study; Level of evidence, 3. METHODS: The records of adolescent athletes who underwent OAT for capitellar OCD with a minimum 2-year follow-up were retrospectively reviewed. Clinical outcomes included elbow range of motion (ROM) and Timmerman-Andrews (T-A) score. A suboptimal outcome was defined as a postoperative T-A score <160. Preoperative radiographs were used to measure proximal migration of the radial head relative to the coronoid process, hypertrophy of the radial head, OCD lesion area, and a 5-grade lateral wall disruption classification; measurement reliability was assessed. Multivariate logistic regression analysis was performed to identify independent predictors of a suboptimal outcome, and receiver operating characteristic (ROC) curve analysis was used to determine the optimal cutoff value for proximal migration. RESULTS: A total of 69 elbows (mean age, 13.6 years; mean follow-up, 48 months) were included. ROM and T-A scores improved significantly after OAT, and all athletes returned to any sports. Of these, 50 elbows (72%) achieved good outcomes, whereas 19 (28%) had suboptimal outcomes. Preoperative proximal migration was significantly greater in the suboptimal outcome group compared with the good outcome group (mean, 2.1 &#xb1; 2.3 vs 0.5 &#xb1; 1.7 mm; P = .002), as were lesion area (mean, 70 &#xb1; 16 vs 58 &#xb1; 20 mm2; P = .02) and lateral wall disruption grade (median, 5 vs 3; P = .01). On multivariate analysis, proximal migration of the radial head was the only independent predictor of a suboptimal outcome (adjusted OR, 1.47 per 1-mm increase; 95% CI, 1.03-2.09; P = .033). ROC analysis showed an area under the curve of 0.72 with an optimal cutoff of 2.2 mm (sensitivity, 56%; specificity, 84%). CONCLUSION: OAT resulted in significant clinical improvement in adolescents with capitellar OCD; however, 28% of patients were classified as having suboptimal outcomes. Preoperative proximal migration of the radial head is an independent predictor of a suboptimal postoperative outcome. A value >2.2 mm may indicate advanced radiocapitellar incongruity, a condition in which OAT may be less effective.

Robot-assisted versus freehand cannulated-screw fixation for femoral neck fractures: a systematic review of technical, clinical and adoption outcomes.

Robot-assisted guidance may improve the technical precision of percutaneous cannulated-screw fixation for femoral neck fractures. Whether these procedural advantages translate into better clinical outcomes remains uncertain. We compared robot-assisted and conventional freehand fixation in adults with femoral neck fractures. MEDLINE, Embase and CINAHL were searched from inception to 15 July 2026 without language restrictions. Google Scholar was used only as a supplementary search source, together with forward and backward citation searching. Comparative studies of robot-assisted versus freehand fluoroscopy-guided cannulated-screw fixation were included. Risk of bias was assessed using RoB 2 and ROBINS-I, with the Newcastle-Ottawa Scale used as a complementary appraisal of non-randomised studies. Random-effects meta-analyses included prediction intervals and prespecified sensitivity analyses. The protocol was registered prospectively (PROSPERO CRD420261465038). Sixteen comparative studies involving 1,293 participants were included. Of these, 597 underwent robot-assisted fixation and 696 underwent freehand fixation. Two studies reporting random allocation and 14 non-randomised studies were included in the study. Robot-assisted fixation was associated with fewer guide-wire manipulations, greater screw-placement accuracy and 13.9 fewer fluoroscopic acquisitions per procedure (95% confidence interval [CI] -20.3 to -7.5). Earlier radiographic healing and modestly higher final Harris Hip Scores were also observed. Pooled estimates suggested lower risks of union failure, avascular necrosis and composite complications. Fluoroscopy duration, overall operative time and reoperation did not differ significantly. Heterogeneity was substantial for several continuous outcomes, with prediction intervals crossing the null for several estimates, indicating that the magnitude of benefit varied considerably between studies. Some clinical associations were also sensitive to eligibility-restricted analyses. Robot-assisted cannulated-screw fixation improves technical execution compared with freehand fixation. Patient-important clinical superiority and economic value have not been established, and evidence concerning learning curves, operator acceptability and system reliability remains insufficient. Current evidence does not support routine widespread adoption; adequately powered multicentre randomised trials incorporating economic and implementation evaluation are required.

Exploring the Diagnostic Utility of Ferumoxytol for Brachial Plexus MR Neurography.

Background Ferumoxytol has been described as an alternative contrast agent for vascular suppression in MR neurography (MRN), but its diagnostic utility in patients has yet to be evaluated. Purpose To evaluate the impact of ferumoxytol on vascular suppression, nerve conspicuity, and evaluation of nerve abnormalities at three-dimensional (3D) brachial plexus MRN, compared with noncontrast and gadolinium-enhanced MRN, in participants with suspected Parsonage-Turner syndrome (PTS) or thoracic outlet syndrome (TOS). Materials and Methods This prospective study included participants who underwent 3D MRN with and/or without gadolinium chelate for clinical suspicion of PTS or TOS and subsequently underwent 3D MRN with ferumoxytol (within 3 months of the clinical examination). Two musculoskeletal radiologists qualitatively evaluated 3D short-tau inversion-recovery fast spin-echo scans for the degree of vascular suppression, nerve conspicuity, and presence of nerve abnormalities. Wilcoxon signed-rank or McNemar tests were used for comparing noncontrast and gadolinium-enhanced scans with ferumoxytol-enhanced scans. Results This study included 18 participants (mean age, 42 years &#xb1; 15.2 [SD]; 10 men). Ferumoxytol-enhanced scans demonstrated improved vascular suppression compared with both noncontrast scans (both raters, P < .001) and gadolinium-enhanced scans (both P = .04). For rater 2, ferumoxytol-enhanced acquisitions demonstrated improved conspicuity of several nerve segments relative to the noncontrast scan, including segments of the suprascapular (P = .01), axillary (P = .02), and long thoracic nerves (P = .004). The distribution of scores for these nerve segments for rater 1 also favored ferumoxytol-enhanced versus noncontrast scans, but the differences were not statistically significant (all P &#x2265; .06). There was no evidence of a difference in nerve conspicuity between ferumoxytol-enhanced and gadolinium-enhanced scans (P &#x2265; .17 for all nerve segments) and also no evidence of discrepancies in abnormal nerve findings between the acquisitions (all P &#x2265; .48). Conclusion Ferumoxytol improved vascular suppression compared with noncontrast and gadolinium-enhanced 3D short-tau inversion-recovery fast spin-echo sequences in brachial plexus MRN, enhancing the conspicuity of several nerve branches versus noncontrast scans, with similar detection of abnormal nerve findings. &#xa9; RSNA, 2026 Supplemental material is available for this article.

Virtual Reality Education for Hospitalized Pediatric Patients Improves Intrinsic Motivation: A Prospective, Randomized Crossover Study.

Hospitalized children experience educational disruption and reduced motivation during prolonged admissions. Despite the availability of in-hospital schools, many cannot participate due to illness severity or isolation precautions. This pragmatic, randomized crossover trial evaluated whether bedside virtual reality (VR) lessons improve intrinsic motivation among inpatients aged 5 to 25 years unable to attend the hospital school. Participants completed both VR-based educational sessions and standard of care (SOC) conditions on consecutive days. The primary outcome was intrinsic motivation, with secondary outcomes including educational self-efficacy, well-being, self-esteem, and parental experience. Of 156 enrolled patients, 100 were analyzed (mean age 11.5 [SD = 4.1 years]; 43.9% female). Intrinsic motivation scores were higher in the VR condition than SOC (P = .0048), and parental satisfaction was also greater (P = .0008). Bedside VR education represents a feasible, acceptable, and scalable adjunct to inpatient learning, supporting intrinsic motivation and caregiver satisfaction during hospitalization.Trial Registration: ClinicalTrials.gov NCT05725395, date first registered November 22, 2022.

Two-Year Outcomes of a 211 Care Coordination Trial.

BACKGROUND AND OBJECTIVES: Early screening for developmental concerns enables timely diagnosis and referral, yet many families face barriers accessing services. Prior work showed that early childhood care coordination could improve timely service connection. This study assessed developmental outcomes among children participating in a randomized controlled trial of Information and Referral Federation of Los Angeles County (211LA). METHODS: Participants, aged 21-42&#xa0;months, were randomized to usual care or the 211LA intervention. Developmental and behavioral measures, including the Parental Evaluation of Developmental Status Developmental Milestones Assessment Level (PEDS-DM-AL) and the Child Behavior Checklist (CBCL), were collected at baseline and 24&#xa0;months later. The sample included 499 participants, 250 in the 211LA intervention and 249 in usual care. Primary analyses examined changes in PEDS-DM-AL and CBCL scores over the 24-month period by study arm. Post hoc analyses compared family characteristics between intervention and control families who enrolled in services. RESULTS: Developmental and behavioral measures showed some clinically insignificant change over time, but these changes did not differ by condition (expressive/receptive language skills mastered: P&#x2009;>&#x2009;.9; autism, attention, aggression, and externalizing behavior T scores: P&#x2009;>&#x2009;.4). Post hoc analyses identified potentially relevant imbalances between the treatment arms at baseline as well as in the subgroup that enrolled in services, with families assigned to the 211LA intervention being more likely to have a non-US born parent and a parent with limited English proficiency compared with families assigned to usual care. Intervention families enrolled in services also used telehealth more frequently and received a lower duration of services than those receiving usual care. CONCLUSIONS: This study measured the indirect influence of service enrollment through 211LA care coordination on developmental outcomes. Although increased service enrollment through 211LA did not affect developmental outcomes, we hypothesize this may be because of several factors, including overrepresentation of a subset of historically underrepresented families in the 211LA intervention, suboptimal performance of our developmental assessment tool, and complexity of conducting a trial of this magnitude during the COVID-19 pandemic, which may have diminished the ability of this trial to demonstrate developmental benefits despite demonstrated service enrollment gains.

Epithelial regeneration in the gastrointestinal tract.

The gastrointestinal tract possesses a remarkable regenerative capacity to maintain tissue homeostasis against various injuries. However, the intestine and stomach exhibit distinct regenerative strategies. In the intestine, damage to Lgr5-positive (Lgr5+) stem cells induces cellular plasticity and the emergence of transient Revival stem cells (RevSCs), a process critically dependent on YAP/TAZ signaling. Conversely, the stomach utilizes paligenosis, where quiescent p57-positive (p57+) mature chief cells act as reserve stem cells, dedifferentiating to restore damaged tissue. Although the cellular origins differ, both organs appear to share some common regenerative features, including transient activation of pro-proliferative programs such as YAP/TAZ signaling. In contrast, whether Retinoic Acid (RA) signaling also serves as a conserved mechanism for regenerative resolution in the stomach remains to be determined. In this review, we discuss the cellular and molecular mechanisms governing regeneration in these two organs. This comparative analysis provides a framework for future research.
