BACKGROUND AND OBJECTIVES Neonatal tracheal intubation is a high-risk procedure, and multiple attempts are associated with adverse events. At our tertiary neonatal intensive care unit, the baseline first-attempt success rate was 45%, which we aimed to increase to over 55% through a quality improvement (QI) initiative. METHODS A multidisciplinary team conducted a QI project using the define-measure-analyze-improve-control framework. Root cause analysis identified poor glottic visualization and patient instability as primary drivers of failure. Plan-do-study-act cycles were carried out (April 2023–July 2024), followed by a sustainability phase (August 2024–May 2025). Key interventions included the phased implementation of video laryngoscopy (VL) as the primary intubation device and the standardization of oxygenation during laryngoscopy using nasal high flow. First-attempt success was tracked using statistical process control, and bimonthly VL use was monitored as a process measure. RESULTS A total of 642 intubations were analyzed. By control chart analysis, the first-attempt success rate increased from a baseline of 45% to a sustained process mean of 61% during the intervention and sustainability phases. VL use increased from 0% at baseline to 70% to 90% during the sustainability phase. Success rates improved across all clinician types and locations. Notably, first-attempt success in infants weighing less than 1000 g increased from 38% at baseline to 62% during the intervention phase. CONCLUSION A systematic QI initiative focused on VL and standardized oxygenation improved and sustained neonatal intubation success rates, exceeding the project aim. The maintenance of high-success rates confirms the durability of these safety improvements.

Portal hypertension is a central driver of morbidity and mortality in advanced chronic liver disease, yet its contribution to death is frequently underestimated owing to underreporting on death certificates. Population-level data on portal hypertension-related mortality trends and disparities in the United States remain limited. We conducted a retrospective, population-based mortality study using the Centers for Disease Control and Prevention Wide-ranging Online Data for Epidemiologic Research Multiple Cause of Death database, identifying deaths with International Statistical Classification of Diseases and Related Health Problems, 10th Revision code K76.6 listed in any cause-of-death field from 1999 to 2023. Crude and age-adjusted mortality rates per 100,000 population were calculated and stratified by sex, U.S. Census region, race/ethnicity, and urban–rural status (the latter restricted to 1999–2020 due to data availability). Temporal trends were assessed using Joinpoint regression, with annual percent change (APC) reported as the primary trend metric and 95% confidence intervals presented for all estimates. A total of 34,551 portal hypertension-related deaths were identified. Overall age-adjusted mortality rates declined sharply from 1999 to 2002 (APC − 12.85%), plateaued for more than a decade, and rose thereafter. Mortality increased significantly in women after 2009 (APC + 6.69%) and in men after 2013 (APC + 6.18%). Among racial and ethnic groups, Hispanic or Latino individuals consistently demonstrated the highest mortality burden throughout the study period, followed by White individuals, whereas Black or African American individuals exhibited comparatively lower but significantly rising rates from 2006 onward. White individuals demonstrated the steepest recent acceleration, with a significant increase after 2014 (APC + 8.51%). Regionally, the South experienced the steepest post-2013 increase, while the Northeast retained the lowest absolute rates despite a significant rise after 2014. Urban populations showed early improvement through 2014 followed by rising mortality, whereas rural populations experienced a later but steeper rise beginning around 2013, with widening urban–rural disparities over time. Portal hypertension-related mortality has risen significantly since the mid-2010s across all demographic and geographic subgroups, with disproportionate burdens among Hispanic individuals, men, rural populations, and residents of the Southern United States. These findings highlight the urgent need for targeted prevention strategies, equitable access to hepatology care, and aggressive management of metabolic and alcohol-related risk factors to reverse this trajectory.

ABSTRACT Biofilm‐associated staphylococcal infections remain exceptionally difficult to treat due to the presence of resilient staphylococcal biofilms and the limited effectiveness of currently available antibiotics. To combat persistent infections, providers are often forced to use prolonged courses of combination antimicrobial therapies that have significant toxicities with limited effectiveness, leading to increased hospital stays, substantial health care costs and a rise in patient morbidity and mortality. Staphylococcus aureus is a dominant cause of recalcitrant biofilms, for which novel non‐antibiotic therapeutics are critically needed. Lysins, a class of protein‐based antimicrobials, rapidly kill staphylococci, exhibit potent anti‐biofilm activity, have a low propensity of resistance development and synergy with antibiotics. To address this unmet need, we evaluate an extracellular vesicle (EV)‐based delivery platform for the engineered anti‐staphylococcal lysin LYSG101, designed to improve stability and localization at sites of infection. Initial proof‐of‐concept work is provided here, demonstrating that human serum‐derived EVs can be loaded with LYSG101 to exert a potent in vitro antimicrobial effect against both planktonic and biofilm forms of S. aureus . EV‐mediated delivery achieved activity equivalent to free lysin, with additional translational advantages including stability and the potential for sustained intra‐articular retention. This work supports further development of the EV‐mediated lysin delivery as a broadly applicable antimicrobial platform, with potential future applications in biofilm‐associated infections, including prosthetic joint infection (PJI).

Background With improvements in in vitro culture techniques, there has been a steady shift in practice to transfer in vitro fertilisation (IVF) embryos at the blastocyst-stage to increase pregnancy rates per embryo transfer (ET) and reduce the risk of multiple pregnancy. In patients with fewer embryos (≤5 zygotes), fresh cleavage-stage ET is still commonly performed to reduce the risk of cycle cancellation if no embryo survives to the blastocyst-stage in vitro. However, evidence for improved outcomes with cleavage-stage embryo transfer in this subgroup of patients is lacking. We will compare blastocyst-stage to cleavage-stage ET with regard to cumulative live birth rates (CLBR) per oocyte retrieval and other patient-centred cycle outcomes in patients with ≤5 zygotes. Methods and analysis Multicentre, randomised pragmatic comparative effectiveness trial with superiority design comparing blastocyst-stage to cleavage-stage ET in patients with ≤5 zygotes. This trial will enrol and randomise 1126 women aged 18–44 undergoing IVF to either fresh cleavage-stage or blastocyst-stage ET at eleven IVF centres. Surplus embryos will be vitrified at the blastocyst-stage. The primary outcome is the CLBR per oocyte retrieval. Secondary outcomes include: multiple pregnancy, pregnancy loss <20 weeks and cycle cancellation. Exploratory outcomes include: live birth per fresh ET, ectopic pregnancy, time to pregnancy, stillbirth, preterm birth, financial burden, patient distress and facilitators and barriers for patient involvement and implementation. All primary analyses will be conducted according to the intent-to-treat principle. We also will report per-protocol analyses as a sensitivity analysis. A multidisciplinary stakeholder team, including a 5-patient stakeholder panel, will participate in study design, conduct and oversight. Ethics and dissemination The Institutional Review Board at Beth Israel Deaconess Medical Center (BIDMC) provides central regulatory oversight. Results will inform timing of embryo transfer in patients with ≤5 zygotes and will be disseminated through academic publications, meeting presentations and communications to advocacy groups and patient participants.

Background: Pregnancies complicated by fetal growth restriction are at increased risk of fetal demise and adverse neonatal outcomes. Distinguishing growth-restricted fetuses from constitutionally small ones remains challenging. Given the variability in current diagnostic criteria and the importance of identifying at-risk fetuses, fetal growth velocity has emerged as a predictor of adverse neonatal outcomes. Objective: To evaluate whether percentile-based fetal growth velocity, defined as change in estimated fetal weight percentile per week, predicts adverse neonatal outcomes in pregnancies affected by fetal growth restriction or small-for-gestational-age neonates. The primary aim was to determine the relationship between growth velocity and a composite of adverse neonatal outcomes. Study Design: This was a retrospective cohort study of pregnant patients 18 - 45 years old who delivered between August 2017 to December 2022 in a single healthcare system. Patients were excluded who had fewer than 2 ultrasounds after 16 weeks gestation, genetic or anatomic abnormalities, or a multiple gestation. Results: 300 patients met all inclusion criteria, and most patients (n=199) delivered at the tertiary care center. Three had an intrauterine fetal demise at a mean gestational age of 35w3d. 74 neonates were admitted to the NICU with a mean length of stay of 8.5 days; 29 required respiratory support. No neonatal deaths occurred. In fetuses with initial estimated fetal weight <3rd percentile (n=33), the probability of composite outcome was increased (50%, 95% CI 44.8-55.2) compared to those >50th percentile (5%, 95% CI 3.7-6.6). In the 3-10th and 10 - 50th percentile subgroups with decelerated growth, composite outcome rates were also increased (56.2% and 44.1%) compared to those with neutral or increased growth velocity. Conclusion: Percentile-based fetal growth velocity is a simple calculation that correlates with adverse neonatal outcomes regardless of initial estimated fetal weight. As fetal growth velocity decreased, our cohort saw increased rates of adverse outcomes. Change in EFW percentile normalizes for gestational age and allows ease of clinical interpretation. Decelerated growth identified fetuses at highest risk, suggesting growth velocity as a useful metric in routine surveillance.

Background The management of osteochondral lesions of the talus (OLT) is challenging, with 2 main options being conservative and surgical management. Orthobiologic therapies come to bridge the gap between these 2 options; however, inconsistencies in indication, composition, and heterogeneous evidence limit clinical decision-making. To address these challenges, 3 International Congress Meetings on Cartilage Repair of the Ankle were convened in Pittsburgh, USA (2017), Dublin, Ireland (2019), and New York, USA (2025) to establish agreement on the role of conservative management and injectable orthobiologic strategies in the treatment of OLT. Methods Seventy-five multidisciplinary experts from over 25 countries and 1 territory participated in a structured Delphi-based consensus process. Blinded surveys, structured questionnaires, and in-person discussions were used to develop and refine statements, supported by literature review and graded evidence (A1–E). Consensus strength was defined as consensus (51%-74%), strong consensus (75%-99%), or unanimous (100%) Results In total, 29 consensus statements were achieved across the 3 meetings. Strong agreement was reached regarding indications and expected outcomes of conservative management, including the role of immobilization and appropriate timing for surgical intervention. Orthobiologic injections, including platelet-rich plasma, concentrated bone marrow aspirate, and hyaluronic acid, were considered appropriate in select patients with persistent symptoms, although no superiority was demonstrated among formulations, preparation methods, or injection strategies. When used as adjuncts to surgical procedures, orthobiologics may improve radiological outcomes, with limited evidence for improvement in clinical outcomes. Technical considerations, including preferred harvest sites and a lack of standardized preparation protocols, were identified, along with key principles for patient counseling Conclusion These international consensus statements establish a standardized framework for the conservative management and use of injectable orthobiologic therapies in OLT. By clarifying indications, technical considerations, and current limitations, this work aims to improve consistency in clinical practice, guide treatment decision-making, and inform future research.

ABSTRACT Objective To provide expert recommendations for the development of a specialty bipolar clinic that promotes best clinical practices for the delivery of safe and effective care. Methods Members of the National Network of Depression Centers (NNDC) Bipolar Clinics Work Group met in a series of 1‐h monthly video calls over 18 months to discuss all aspects of their respective institution's bipolar clinics, including services provided, administrative processes, staffing models, characteristics of patients treated, patient volumes, finances, and research. The group also invited psychiatrists from outside of the NNDC who ran large bipolar clinics to contribute their thoughts and experiences on the subject. In addition, the NNDC sent a 20‐question survey to all 27 sites asking clinic directors specific questions about their bipolar clinics, if applicable. Further meetings and discussions incorporating results from the survey took place to produce a comprehensive set of recommendations. Results Twenty‐one of 27 NNDC sites (81%) responded to the survey. Twelve of 21 (57%) sites had a specific bipolar clinic, and another 4 (19%) were looking to start one. Clinics were based in university settings. The meetings, clinic survey, and discussions resulted in 10 recommendations describing services and operations for bipolar specialty clinics. Conclusions Given the complexity of bipolar disorder, specialty clinics are important to enhance care. Clinics with a wide array of services that include consultation, medication management, bipolar‐specific psychotherapies, and patient/family psychoeducation provide the most comprehensive care. Challenges to these clinics include maintaining ongoing patient access as well as ensuring long‐term financial stability.
