Diagnostic and management challenges of a rare case of caesarean scar pregnancy in a low-resource setting: a case report.

Caesarean scar pregnancy is a rare type of ectopic pregnancy with the potential for catastrophic outcomes. A high index of suspicion is required for prompt diagnosis and intervention to improve outcomes. This report describes a rare case of Caesarean scar pregnancy, which was initially misdiagnosed as a threatened miscarriage and cervical ectopic pregnancy. A 35-year-old multiparous lady with two previous caesarean sections presented to the Gynaecology Unit of the Nnamdi Azikiwe University Teaching Hospital (NAUTH), Nigeria, at an estimated gestational age of 10 weeks, with recurrent vaginal bleeding of eight weeks' duration. She was referred to our facility from a private hospital, where she had first been managed as a case of threatened miscarriage and later as a cervical ectopic pregnancy. The transvaginal ultrasound in our facility was in keeping with a viable Caesarean scar pregnancy. The urine pregnancy test was positive, and the quantitative serum beta human chorionic gonadotropin was 75.6 mIU/ml. She had initial medical treatment with a combination of systemic multidose and intrauterine sac methotrexate and, subsequently, hysterotomy. Following systemic and local methotrexate, there was the demise of the foetus, which was evacuated at hysterotomy, and the uterine scar defect was repaired. She was discharged home in stable clinical condition one week after surgery. Her serum beta human chorionic gonadotropin dropped to 51.6 mIU/mL two weeks post-hysterotomy, and her urine pregnancy test became negative three weeks later. Though rare, caesarean scar pregnancy should be considered a differential diagnosis in reproductive-aged women with a previous caesarean section who present with vaginal bleeding in the first trimester.

Rapid Assessment of Biomarkers on Single Extracellular Vesicles Using "Catch and Display" on Ultrathin Nanoporous Silicon Nitride Membranes.

Extracellular vesicles (EVs) are particles released from cells that facilitate intercellular communication and have tremendous diagnostic and therapeutic potential. Bulk assays lack the sensitivity to detect rare EV subsets relevant to disease, and while single EV analysis techniques remedy this, they are often undermined by complicated detection schemes and prohibitive instrumentation. To address these issues, a microfluidic technique for EV characterization called "catch and display for liquid biopsy (CAD-LB)" is proposed. In this method, minimally processed samples are pipette-injected and fluorescently labeled EVs are captured in the nanopores of an ultrathin membrane.  This enables the rapid assessment of EV number and biomarker colocalization by light microscopy. Here, nanoparticles are used to define the accuracy and dynamic range for counting and colocalization. The same assessments are then made for purified EVs and for unpurified EVs in plasma. Biomarker detection is validated using CD9 and Western blot analysis to confirm that CAD-LB accurately reports relative protein expression levels. Using unprocessed conditioned media, CAD-LB captures the known increase in EV-associated ICAM-1 following endothelial cell cytokine stimulation. Finally, to demonstrate CAD-LB's clinical potential, EV biomarkers indicative of immunotherapy responsiveness are successfully detected in the plasma of bladder cancer patients treated with immune checkpoint blockade.

The Implementation of Enhanced Recovery After Spine Surgery in High and Low/Middle-income Countries: A Systematic Review and Meta-Analysis.

In this review article, we explore the implementation and outcomes of enhanced recovery after spine surgery (spine ERAS) across different World Bank country-income levels. A systematic literature search was conducted through PubMed, Embase, Scopus, and CINAHL databases for articles on the implementation of spine ERAS in both adult and pediatric populations. Study characteristics, ERAS elements, and outcomes were analyzed and meta-analyses were performed for length of stay (LOS) and cost outcomes. The number of spine ERAS studies from low-middle-income countries (LMICs) increased since 2017, when the first spine ERAS implementation study was published. LMICs were more likely than high-income countries (HICs) to conduct studies on patients aged ≥18 years (odds ratio [OR], 6.00; 95% CI, 1.58-42.80), with sample sizes 51 to 100 (OR, 4.50; 95% CI, 1.21-22.90), and randomized controlled trials (OR, 7.25; 95% CI, 1.77-53.50). Preoperative optimization was more frequently implemented in LMICs than in HICs (OR, 2.14; 95% CI, 1.06-4.41), and operation time was more often studied in LMICs (OR 3.78; 95% CI, 1.77-8.35). Implementation of spine ERAS resulted in reductions in LOS in both LMIC (-2.06; 95% CI, -2.47 to -1.64 d) and HIC (-0.99; 95% CI, -1.28 to -0.70 d) hospitals. However, spine ERAS implementation did result in a significant reduction in costs. This review highlights the global landscape of ERAS implementation in spine surgery, demonstrating its effectiveness in reducing LOS across diverse settings. Further research with standardized reporting of ERAS elements and outcomes is warranted to explore the impact of spine ERAS on cost-effectiveness and other patient-centered outcomes.

Transoral robotic surgery for pediatric upper airway pathology: An institutional update.

OBJECTIVE: Provide an update on our institution's experience with utilizing transoral robotic surgery (TORS) in pediatric airway surgery and compare these results to surgery by traditional methods. METHODS: Pediatric patients who underwent TORS for treatment of upper airway pathology between 2010 and 2021 at our institution were retrospectively identified and compared to patients with the same or similar pathology who underwent a traditional (open or endoscopic) surgical approach over the same time period. Outcomes of interest included patient demographics, operative times, adverse events, hospital length of stay (LOS), and modified barium swallow (MBSS) results. RESULTS: Forty children (19M, 21F) underwent 46 TORS procedures. Mean age was 6.4 years (range: 6 days-17 years). Most commonly treated pathology included: laryngeal clefts (LC) (n = 18), lymphatic malformations (n = 9), and base of tongue masses (n = 7). Surgical time was decreased in traditional type I LC repairs (mean: 111 vs 149 min, P = 0.04) and lymphatic malformation excisions (59 vs 120 min, p = 0.005). Hospital LOS was increased in TORS type I LC repairs (2.6 vs 1.2 days, P = 0.04). Adverse event rate was similar between TORS and traditional cohorts (17 % vs 16 % cases, P = 0.9). Postoperative MBSS results were improved for TORS type I LC repairs at 6 months (70 % vs 33 %, P = 0.09) and 12 months (82 % vs 43 %, P = 0.05). CONCLUSIONS: Pediatric TORS is practical and safe and has comparable outcomes to traditional surgery. Robotic-assisted LC repair displayed improved postoperative swallow results versus traditional approaches and may be particularly useful in recurrent cases.

Applications of artificial intelligence for adolescent idiopathic scoliosis: mapping the evidence.

PURPOSE: Adolescent idiopathic scoliosis (AIS) is a common spinal deformity with varying progression, complicating treatment decisions. Artificial intelligence (AI) and machine learning (ML) are increasingly prominent in orthopedic care, aiding in diagnosis, risk-stratification, and treatment guidance. This scoping review outlines AI applications in AIS. METHODS: This study followed PRISMA-ScR guidelines and included articles that reported the development, use, or validation of AI models for treating, diagnosing, or predicting clinical outcomes in AIS. RESULTS: 40 full-text articles were included, with most studies published in the last 5 years (77.5%). Common ML techniques were convolutional neural networks (55%), decision trees and random forests (15%), and artificial neural networks (15%). Most AI applications in AIS were for imaging analysis (25/40; 62.5%), focusing on automatic measurement of Cobb angle, and axial vertebral rotation (13/25; 52%) and curve classification/severity (13/25; 52%). Prediction was the second most common application (15/40; 37.5%), with studies predicting curve progression (9/15; 60%), and Cobb angles (9/15; 60%). Only 15 studies (37.5%) reported clinical implementation guidelines for AI in AIS management. 52.5% of studies reported model accuracy, with an average of 85.4%. CONCLUSION: This review highlights the applications of AI in AIS care, notably including automatic radiographic analysis, curve type classification, prediction of curve progression, and AIS diagnosis. However, the current lack of clear clinical implementation guidelines, model transparency, and external validation of studied models limits clinician trust and the generalizability and applicability of AI in AIS management.

Investigating Substance Use as a Coping Strategy Among Adolescent Psychiatric Inpatients: A Comparative Analysis Before and During the COVID-19 Pandemic.

The COVID-19 pandemic resulted in significant changes in daily life, potentially impacting mental health and substance use behavior. Research on COVID-related changes in adolescent substance use have yielded mixed findings. The current cross-sectional chart review study compared rates of past-year substance use before and during COVID-19 among adolescent psychiatric inpatients, and investigated how motives for coping with COVID-19 changes were related to psychiatric acuity, and past-year substance use. Count models assessed if the number of past-year days of alcohol and cannabis use was higher among adolescents (n = 491, 11-18 years, 61% female) hospitalized during COVID-19 (3/14/20 to 4/5/21) versus adolescents hospitalized before COVID-19 (8/30/2019 to 3/13/20). For a subsample of COVID-19 inpatients (n = 124; 75% female), we evaluated psychiatric correlates of endorsing substances to cope with COVID-19 changes/rules. Results indicated adolescents admitted during COVID-19 reported significantly more past-year alcohol and cannabis use days than adolescents admitted before COVID-19. Adolescents endorsed using alcohol (19%), cannabis (33%), and e-cigarettes/vaping (25%) to cope with COVID-19. E-cigarette/vaping to cope with COVID-19 was significantly related to lifetime suicide attempt. Endorsing alcohol or cannabis to cope with COVID-19 was associated with a significantly greater number of past-year use days for each respective substance. Adolescent psychiatric inpatients admitted during COVID-19 reported more substance use days than adolescents admitted before COVID-19. Using substances to cope was linked to psychiatric correlates (e.g., suicidality). Assessing the presence and function of substance use in this population may be important to identify, treat, and prevent compounding negative outcomes during times of community stress.

Treatment of Locally Recurrent Rectal Cancer: A Review.

ABSTRACT: Up to 10% of patients with locally advanced rectal cancer will experience locoregional recurrence. In the setting of prior surgery and often radiation and chemotherapy, these represent uniquely challenging cases. When feasible, surgical resection offers the best chance for oncologic control yet risks significant morbidity. Studies have consistently indicated that a negative surgical resection margin is the strongest predictor of oncologic outcomes. Chemoradiation is often recommended to increase the chance of an R0 resection, and in cases of close/positive margins, intraoperative radiation/brachytherapy can be utilized. In patients who are not surgical candidates, radiation can provide symptomatic relief. Ongoing phase III trials are aiming to address questions regarding the role of reirradiation and induction multiagent chemotherapy regimens in this population.

Leveraging biotin-based proximity labeling to identify cellular factors governing early alphaherpesvirus infection.

Neurotropic alphaherpesviruses, including herpes simplex virus type 1 and pseudorabies virus, establish a lifelong presence within the peripheral nervous system of their mammalian hosts. Upon entering cells, two conserved tegument proteins, pUL36 and pUL37, traffic DNA-containing capsids to nuclei. These proteins support long-distance retrograde axonal transport and invasion of the nervous system in vivo. To better understand how pUL36 and pUL37 function, recombinant viral particles carrying BioID2 fused to these proteins were produced to biotinylate cellular proteins in their proximity (<10 nm) during infection. Eighty-six high-confidence host proteins were identified by mass spectrometry and subsequently targeted by CRISPR-Cas9 gene editing to assess their contributions to early infection. Proteins were identified that both supported and antagonized infection in immortalized human epithelial cells. The latter included zyxin, a protein that localizes to focal adhesions and regulates actin cytoskeletal dynamics. Zyxin knockout cells were hyper-permissive to infection and could be rescued with even modest expression of GFP-zyxin. These results provide a resource for studies of the virus-cell interface and identify zyxin as a novel deterrent to alphaherpesvirus infection.IMPORTANCENeuroinvasive alphaherpesviruses are highly prevalent with many members found across mammals [e.g., herpes simplex virus type 1 (HSV-1) in humans and pseudorabies virus in pigs]. HSV-1 causes a range of clinical manifestations from cold sores to blindness and encephalitis. There are no vaccines or curative therapies available for HSV-1. A fundamental feature of these viruses is their establishment of lifelong infection of the nervous system in their respective hosts. This outcome is possible due to a potent neuroinvasive property that is coordinated by two proteins: pUL36 and pUL37. In this study, we explore the cellular protein network in proximity to pUL36 and pUL37 during infection and examine the impact of knocking down the expression of these proteins upon infection.

Variation in Androgen Deprivation Therapy Use Among Men With Intermediate-Risk Prostate Cancer: Results From a Statewide Radiation Oncology Quality Consortium.

PURPOSE: For men with intermediate-risk prostate cancer treated with definitive therapy, the addition of androgen deprivation therapy (ADT) reduces the risk of distant metastasis and cancer-related mortality. However, the absolute benefit of ADT varies by baseline cancer risk. Estimates of prognosis have improved over time, and little is known about ADT decision making in the modern era. We sought to characterize variability and identify factors associated with intended ADT use within the Michigan Radiation Oncology Quality Consoritum (MROQC). MATERIALS AND METHODS: Patients with localized prostate cancer undergoing definitive radiation therapy were enrolled from June 9, 2020, to June 26, 2023 (n = 815). Prospective data were collected using standardized patient, physician, and physicist forms. Intended ADT use was prospectively defined and was the primary outcome. Associations with patient, tumor, and practice-related factors were tested with multivariable analyses. Random intercept modeling was used to estimate facility-level variability. RESULTS: Five hundred seventy patients across 26 facilities were enrolled with intermediate-risk disease. ADT was intended for 46% of men (n = 262/570), which differed by National Comprehensive Cancer Network favorable intermediate-risk (23.5%, n = 38/172) versus unfavorable intermediate-risk disease (56.3%, n = 224/398; P < .001). After adjusting for the statewide case mix, the predicted probability of intended ADT use varied significantly across facilities, ranging from 15.4% (95% CI, 5.4%-37.0%) to 71.7% (95% CI, 57.0%-82.9%), with P < .01. Multivariable analyses showed that grade group 3 (OR, 4.60 [3.20-6.67]), ≥50% positive cores (OR, 2.15 [1.43-3.25]), and prostate-specific antigen 10 to 20 (OR, 1.87 [1.24-2.84]) were associated with ADT use. Area under the curve was improved when incorporating MRI adverse features (0.76) or radiation treatment variables (0.76), but there remained significant facility-level heterogeneity in all models evaluated (P < .05). CONCLUSIONS: Within a state-wide consortium, there is substantial facility-level heterogeneity in intended ADT use for men with intermediate-risk prostate cancer. Future efforts are necessary to identify patients who will benefit most from ADT and to develop strategies to standardize appropriate use.

Intricacies of Human-AI Interaction in Dynamic Decision-Making for Precision Oncology: A Case Study in Response-Adaptive Radiotherapy.

Background: Adaptive treatment strategies that can dynamically react to individual cancer progression can provide effective personalized care. Longitudinal multi-omics information, paired with an artificially intelligent clinical decision support system (AI-CDSS) can assist clinicians in determining optimal therapeutic options and treatment adaptations. However, AI-CDSS is not perfectly accurate, as such, clinicians' over/under reliance on AI may lead to unintended consequences, ultimately failing to develop optimal strategies. To investigate such collaborative decision-making process, we conducted a Human-AI interaction case study on response-adaptive radiotherapy (RT). Methods: We designed and conducted a two-phase study for two disease sites and two treatment modalities-adaptive RT for non-small cell lung cancer (NSCLC) and adaptive stereotactic body RT for hepatocellular carcinoma (HCC)-in which clinicians were asked to consider mid-treatment modification of the dose per fraction for a number of retrospective cancer patients without AI-support (Unassisted Phase) and with AI-assistance (AI-assisted Phase). The AI-CDSS graphically presented trade-offs in tumor control and the likelihood of toxicity to organs at risk, provided an optimal recommendation, and associated model uncertainties. In addition, we asked for clinicians' decision confidence level and trust level in individual AI recommendations and encouraged them to provide written remarks. We enrolled 13 evaluators (radiation oncology physicians and residents) from two medical institutions located in two different states, out of which, 4 evaluators volunteered in both NSCLC and HCC studies, resulting in a total of 17 completed evaluations (9 NSCLC, and 8 HCC). To limit the evaluation time to under an hour, we selected 8 treated patients for NSCLC and 9 for HCC, resulting in a total of 144 sets of evaluations (72 from NSCLC and 72 from HCC). Evaluation for each patient consisted of 8 required inputs and 2 optional remarks, resulting in up to a total of 1440 data points. Results: AI-assistance did not homogeneously influence all experts and clinical decisions. From NSCLC cohort, 41 (57%) decisions and from HCC cohort, 34 (47%) decisions were adjusted after AI assistance. Two evaluations (12%) from the NSCLC cohort had zero decision adjustments, while the remaining 15 (88%) evaluations resulted in at least two decision adjustments. Decision adjustment level positively correlated with dissimilarity in decision-making with AI [NSCLC: ρ = 0.53 ( p < 0.001); HCC: ρ = 0.60 ( p < 0.001)] indicating that evaluators adjusted their decision closer towards AI recommendation. Agreement with AI-recommendation positively correlated with AI Trust Level [NSCLC: ρ = 0.59 ( p < 0.001); HCC: ρ = 0.7 ( p < 0.001)] indicating that evaluators followed AI's recommendation if they agreed with that recommendation. The correlation between decision confidence changes and decision adjustment level showed an opposite trend [NSCLC: ρ = -0.24 ( p = 0.045), HCC: ρ = 0.28 ( p = 0.017)] reflecting the difference in behavior due to underlying differences in disease type and treatment modality. Decision confidence positively correlated with the closeness of decisions to the standard of care (NSCLC: 2 Gy/fx; HCC: 10 Gy/fx) indicating that evaluators were generally more confident in prescribing dose fractionations more similar to those used in standard clinical practice. Inter-evaluator agreement increased with AI-assistance indicating that AI-assistance can decrease inter-physician variability. The majority of decisions were adjusted to achieve higher tumor control in NSCLC and lower normal tissue complications in HCC. Analysis of evaluators' remarks indicated concerns for organs at risk and RT outcome estimates as important decision-making factors. Conclusions: Human-AI interaction depends on the complex interrelationship between expert's prior knowledge and preferences, patient's state, disease site, treatment modality, model transparency, and AI's learned behavior and biases. The collaborative decision-making process can be summarized as follows: (i) some clinicians may not believe in an AI system, completely disregarding its recommendation, (ii) some clinicians may believe in the AI system but will critically analyze its recommendations on a case-by-case basis; (iii) when a clinician finds that the AI recommendation indicates the possibility for better outcomes they will adjust their decisions accordingly; and (iv) When a clinician finds that the AI recommendation indicate a worse possible outcome they will disregard it and seek their own alternative approach.

Rapid Assessment of Biomarkers on Single Extracellular Vesicles Using 'Catch and Display' on Ultrathin Nanoporous Silicon Nitride Membranes.

Extracellular vesicles (EVs) are particles secreted by all cells that carry bioactive cargo and facilitate intercellular communication with roles in normal physiology and disease pathogenesis. EVs have tremendous diagnostic and therapeutic potential and accordingly, the EV field has grown exponentially in recent years. Bulk assays lack the sensitivity to detect rare EV subsets relevant to disease, and while single EV analysis techniques remedy this, they are undermined by complicated detection schemes often coupled with prohibitive instrumentation. To address these issues, we propose a microfluidic technique for EV characterization called 'catch and display for liquid biopsy (CAD-LB)'. CAD-LB rapidly captures fluorescently labeled EVs in the similarly-sized pores of an ultrathin silicon nitride membrane. Minimally processed sample is introduced via pipette injection into a simple microfluidic device which is directly imaged using fluorescence microscopy for a rapid assessment of EV number and biomarker colocalization. In this work, nanoparticles were first used to define the accuracy and dynamic range for counting and colocalization by CAD-LB. Following this, the same assessments were made for purified EVs and for unpurified EVs in plasma. Biomarker detection was validated using CD9 in which Western blot analysis confirmed that CAD-LB faithfully recapitulated differing expression levels among samples. We further verified that CAD-LB captured the known increase in EV-associated ICAM-1 following the cytokine stimulation of endothelial cells. Finally, to demonstrate CAD-LB's clinical potential, we show that EV biomarkers indicative of immunotherapy responsiveness are successfully detected in the plasma of bladder cancer patients undergoing immune checkpoint blockade.

Co-clustering of EphB6 and ephrinB1 in trans restrains cancer cell invasion.

EphB6 is an understudied ephrin receptor tyrosine pseudokinase that is downregulated in multiple types of metastatic cancers. Unlike its kinase-active counterparts which autophosphorylate and transmit signals upon intercellular interaction, little is known about how EphB6 functions in the absence of intrinsic kinase activity. Here, we unveil a molecular mechanism of cell-cell interaction driven by EphB6. We identify ephrinB1 as a cognate ligand of EphB6 and show that in trans interaction of EphB6 with ephrinB1 on neighboring cells leads to the formation of large co-clusters at the plasma membrane. These co-clusters exhibit a decreased propensity towards endocytosis, suggesting a unique characteristic for this type of cell-cell interaction. Using lattice light-sheet microscopy, 3D structured illumination microscopy and cryo-electron tomography techniques, we show that co-clustering of EphB6 and ephrinB1 promotes the formation of double-membrane tubular structures between cells. Importantly, we also demonstrate that these intercellular structures stabilize cell-cell adhesion, leading to a reduction in the invasive behavior of cancer cells. Our findings rationalize a role for EphB6 pseudokinase as a tumor suppressor when interacting with its ligands in trans.

Clinical validation of circulating GDF15/MIC-1 as a marker of response to docetaxel and survival in men with metastatic castration-resistant prostate cancer.

BACKGROUND: Elevated circulating growth differentiation factor (GDF15/MIC-1), interleukin 4 (IL4), and IL6 levels were associated with resistance to docetaxel in an exploratory cohort of men with metastatic castration-resistant prostate cancer (mCRPC). This study aimed to establish level 2 evidence of cytokine biomarker utility in mCRPC. METHODS: IntVal: Plasma samples at baseline (BL) and Day 21 docetaxel (n = 120). ExtVal: Serum samples at BL and Day 42 of docetaxel (n = 430). IL4, IL6, and GDF15 levels were measured by ELISA. Monocytes and dendritic cells were treated with 10% plasma from men with high or low GDF15 or recombinant GDF15. RESULTS: IntVal: Higher GDF15 levels at BL and Day 21 were associated with shorter overall survival (OS) (BL; p = 0.03 and Day 21; p = 0.004). IL4 and IL6 were not associated with outcomes. ExtVal: Higher GDF15 levels at BL and Day 42 predicted shorter OS (BL; p < 0.0001 and Day 42; p < 0.0001). Plasma from men with high GDF15 caused an increase in CD86 expression on monocytes (p = 0.03), but was not replicated by recombinant GDF15. CONCLUSIONS: Elevated circulating GDF15 is associated with poor prognosis in men with mCRPC receiving docetaxel and may be a marker of changes in the innate immune system in response to docetaxel resistance. These findings provide a strong rationale to consider GDF15 as a biomarker to guide a therapeutic trial of drugs targeting the innate immune system in combination with docetaxel in mCRPC.

Quality Assurance for Stereotactic Body Radiation Therapy for Gynecologic Malignancies.

The use of stereotactic body radiation therapy (SBRT) is not well studied or reported in the treatment of gynecologic malignancies, despite its success in the definitive management of other cancer sites. This report describes a rigorous quality assurance process for patients to undergo dose escalation to the pelvis via stereotactic photon beam irradiation. Patients who receive SBRT must be ineligible for conventional brachytherapy boost and undergo comprehensive informed consent. Fiducial placement, bowel prep, Foley catheter placement with standardized bladder filling, computerized tomography (CT) simulation with whole-body immobilization, magnetic resonance imaging (MRI)-assisted target delineation, planning aims based on the established brachytherapy literature, and physics consultation for SBRT plan optimization are necessary. Prior to each fraction, the simulation position is reproduced and verified with on-table cone beam CT, and the position is maintained with whole-body immobilization. Following treatment, the treating physician is active in survivorship and toxicity management. Gynecologic SBRT is an ongoing area of study, and preliminary successes in delivering high-quality stereotactic dose escalation suggest prospective investigation is warranted. By adhering to strict quality control measures and following a pre-defined best standard of practice, patients with gynecologic malignancies who are ineligible for traditional brachytherapy procedures can be safely treated with SBRT.

Pediatric Robotic Laryngeal Cleft Repair.

OBJECTIVE: Compare surgical and swallow outcomes in robotic versus traditional laryngeal cleft (LC) repairs. STUDY DESIGN: Retrospective cohort study. SETTING: Tertiary care pediatric hospital. METHODS: Pediatric patients who underwent robotic or traditional (open or endoscopic) LC repair between 2010 and 2021 were identified. Patient characteristics, operative times, adverse events, hospital length of stay (LOS), and modified barium swallow study (MBSS) results were compared. RESULTS: Eighteen robotic and thirty traditional LC repairs were identified. Mean surgical (149 vs 111 min, P < .05) and OR times (207 vs 139 min, P < .002) were increased for robotic type I LC repairs, but were similar for type II and III LC. Mean hospital LOS was increased for robotic type I LC repairs (2.6 vs 1.2 days, P < .006), but was decreased for type II (4 vs 12.2 days) and type III (4.3 vs 94.5 days) LC. Postoperative MBSS results were improved for robotic type I LC repairs at 12 months (82% vs 43%, P = .05), and trended toward improvement at 6 months for type II (75% vs 22%), and type III (67% vs 50%) LC repairs, although significance was limited for type II and III LC due to the number of subjects. A robotic approach was used successfully to revise all recurrent LC that failed traditional repairs. CONCLUSION: Robotic type 1 LC repairs demonstrated increased operative times and hospital LOS but improved postoperative swallow outcomes compared to traditional approaches may be particularly useful in cases of recurrent clefts.

Pain screening in youth with sickle cell disease: A quality improvement study.

BACKGROUND: Youth with sickle cell disease (SCD) face several challenges as they age, including increased pain frequency, duration, and interference. The purpose of this study was to (i) determine the feasibility of routine pain screening; (ii) identify and describe various clinical pain presentations; and (iii) understand preferences/resources related to engaging in integrative health and medicine (IHM) modalities within an outpatient pediatric SCD clinic. METHODS: During routine outpatient visits, patients aged 8-18 completed measures of pain frequency, duration, and chronic pain risk (Pediatric Pain Screening Tool [PPST]). Participants screening positive for (i) persistent or chronic pain or (ii) medium or high risk for persistent symptoms and disability on the PPST were asked to complete measures of pain interference, pain catastrophizing, and interest in/resources for engaging in IHM modalities. RESULTS: Between March 2022 and May 2023, 104/141 (73.8%) patients who attended at least one outpatient visit were screened. Of these 104 (mean age 12.46, 53.8% female, 63.5% HbSS), 34 (32.7%) reported persistent or chronic pain, and 48 (46.2%) reported medium or high risk for persistent symptoms and disability. Patients completing subsequent pain screening measures reported a mean pain interference T-score of 53.2 ± 8.8 and a mean pain catastrophizing total score of 24.3 ± 10.2. Patients expressed highest interest in music (55.6%) and art therapy (51.9%) and preferred in-person (81.5%) over virtual programming (22.2%). CONCLUSIONS: Comprehensive pain screening is feasible within pediatric SCD care. Classifying patients by PPST risk may provide a means of triaging patients to appropriate services to address pain-related psychosocial factors.

Iterative assessment of a sports rehydration beverage containing a novel amino acid formula on water uptake kinetics.

PURPOSE: Rapid gastric emptying and intestinal absorption of beverages is essential for rapid rehydration, and certain amino acids (AA) may augment fluid delivery. Three sugar-free beverages, containing differing AA concentrations (AA + PZ), were assessed for fluid absorption kinetics against commercial sugar-free (PZ, GZ) and carbohydrate-containing (GTQ) beverages. METHODS: Healthy individuals (n = 15-17 per study) completed three randomised trials. Three beverages (550-600 mL) were ingested in each study (Study 1: AA + PZ [17.51 g/L AA], PZ, GZ; Study 2: AA + PZ [6.96 g/L AA], PZ, GZ; Study 3: AA + PZ [3.48 g/L AA], PZ, GTQ), containing 3.000 g deuterium oxide (D2O). Blood samples were collected pre-, 2-min, 5-min, and every 5-min until 60-min post-ingestion to quantify maximal D2O enrichment (Cmax), time Cmax occurred (Tmax) and area under the curve (AUC). RESULTS: Study 1: AUC (AA + PZ: 15,184 ± 3532 δ‰ vs. VSMOW; PZ: 17,328 ± 3153 δ‰ vs. VSMOW; GZ: 17,749 ± 4204 δ‰ vs. VSMOW; P ≤ 0.006) and Tmax (P ≤ 0.005) were lower for AA + PZ vs. PZ/GZ. Study 2: D2O enrichment characteristics were not different amongst beverages (P ≥ 0.338). Study 3: Cmax (AA + PZ: 440 ± 94 δ‰ vs. VSMOW; PZ: 429 ± 83 δ‰ vs. VSMOW; GTQ: 398 ± 81 δ‰ vs. VSMOW) was greater (P = 0.046) for AA + PZ than GTQ, with no other differences (P ≥ 0.106). CONCLUSION: The addition of small amounts of AA (3.48 g/L) to a sugar-free beverage increased fluid delivery to the circulation compared to a carbohydrate-based beverage, but greater amounts (17.51 g/L) delayed delivery.

Anterior cervical osteotomy of diffuse idiopathic skeletal hyperostosis lesions with computer-assisted navigation surgery: A case report.

Key Clinical Message: Diffuse idiopathic skeletal hyperostosis (DISH) involves spine ligament ossification. Computer-assisted navigation (CAN) effectively aids complex surgeries, such as anterior cervical osteotomy, to alleviate progressive DISH-related dysphagia. Abstract: We describe a 68-year-old man with sudden onset dysphagia to both solids and liquids. Radiographic Imaging revealed DISH lesions from C2 down to the thoracic spine. The patient was successfully treated with CAN anterior osteotomy and resection of DISH lesions from C3-C6 and had complete symptom relief within 2 weeks post-operatively.

Effectiveness of Medical Music Therapy Practice: Integrative Research Using the Electronic Health Record: Rationale, Design, and Population Characteristics.

Background: Several clinical trials support the efficacy of music therapy (MT) for improving outcomes in hospitalized patients, but few studies have evaluated the real-world delivery and integration of MT across multiple medical centers. This article describes the rationale, design, and population characteristics of a retrospective study examining the delivery and integration of MT within a large health system. Methods: A retrospective electronic health record (EHR) review was conducted of hospitalized patients seen by and/or referred to MT between January 2017 and July 2020. MT was provided across ten medical centers, including an academic medical center, a freestanding cancer center, and eight community hospitals. Discrete demographic, clinical, and MT treatment and referral characteristics were extracted from the EHR, cleaned, and organized using regular expressions functions, and they were summarized using descriptive statistics. Results: The MT team (average 11.6 clinical fulltime equivalent staff/year) provided 14,261 sessions to 7378 patients across 9091 hospitalizations. Patients were predominantly female (63.7%), White (54.3%) or Black/African American (44.0%), 63.7 ± 18.5 years of age at admission, and insured under Medicare (51.1%), Medicaid (18.1%), or private insurance (14.2%). Patients' hospitalizations (median length of stay: 5 days) were primarily for cardiovascular (11.8%), respiratory (9.9%), or musculoskeletal (8.9%) conditions. Overall, 39.4% of patients' hospital admissions included a mental health diagnosis, and 15.4% were referred to palliative care. Patients were referred by physicians (34.7%), nurses (29.4%), or advanced practice providers (24.7%) for coping (32.0%), anxiety reduction (20.4%), or pain management (10.1%). Therapists provided sessions to patients discharged from medical/surgical (74.5%), oncology (18.4%), or intensive care (5.8%) units. Conclusions: This retrospective study indicates that MT can be integrated across a large health system for addressing the needs of socioeconomically diverse patients. However, future research is needed to assess MT's impact on health care utilization (i.e., length of stay and rates of readmission) and immediate patient-reported outcomes.

Innovative vision rehabilitation method for epiretinal membrane: Enhancing visual functions through Biofeedback Training.

Purpose: To report a case with epiretinal membrane (ERM) treated with audio-luminous Biofeedback training (BT) which resulted in improvement of monocular and binocular visual functions. Observations: We report a case of ERM with distance Best Corrected Visual Acuity (BCVA) of 20/40 in the right dominant eye, and 20/20 in the left eye. The main symptom was binocular blurry vision, and the patient did not desire to pursue posterior vitrectomy due to its risks. Using a 10-2 microperimetry test with the MAIA Microperimeter, it was possible to identify an inferior paracentral relative scotoma in the right eye with splitting fixation. The right eye was trained with five 20-minute sessions with Biofeedback training towards a trained retinal locus (TRL) with better retinal sensitivity and 1.46° superior and temporal to the current preferred retinal locus (PRL). After training, the patient reported total improvement of symptoms, and BCVA was 20/25 in the right eye and 20/20 in the left eye. Conclusions and importance: Biofeedback training is a valuable treatment with no known adverse effects that can be performed as an alternative to patients with ERM with no surgical indication and debilitating symptoms, or as a post-surgery adjuvant treatment.
