Biodistribution of Polymeric Nanoparticles following in utero Delivery to a Nonhuman Primate.

Introduction: Monogenic diseases can be diagnosed before birth. Systemic fetal administration of nanoparticles (NPs) grants therapeutic access to developing stem cell populations impacted by these classes of disease. Delivery of editing reagents in these NPs administered before birth has yielded encouraging results in preclinical mouse models of monogenic diseases.

Learning health system research as a catalyst for promoting physician wellness: EHR InBasket Spring cleaning and team-based compassion practice.

Introduction: Addressing physician burnout is critical for healthcare systems. As electronic health record (EHR) workload and teamwork have been identified as major contributing factors to physician well-being, we aimed to mitigate burnout through EHR-based interventions and a compassion team practice (CTP), targeting EHR workload and team cohesion.

Methods: A modified stepped wedge-clustered randomized trial was conducted, involving specialties with heavy InBasket workloads.

Development and Validation of a Deep Learning Model for Prediction of Adult Physiological Deterioration.

Background: Prediction-based strategies for physiologic deterioration offer the potential for earlier clinical interventions that improve patient outcomes. Current strategies are limited because they operate on inconsistent definitions of deterioration, attempt to dichotomize a dynamic and progressive phenomenon, and offer poor performance.

Objective: Can a deep learning deterioration prediction model (Deep Learning Enhanced Triage and Emergency Response for Inpatient Optimization [DETERIO]) based on a consensus definition of deterioration (the Adult Inpatient Decompensation Event [AIDE] criteria) and that approaches deterioration as a state "value-estimation" problem outperform a commercially available deterioration score?

Derivation Cohort: The derivation cohort contained retrospective patient data collected from both inpatient services (inpatient) and emergency departments (EDs) of two hospitals within the University of California San Diego Health System.

Predicting Hospital Readmission among Patients with Sepsis Using Clinical and Wearable Data.

Sepsis is a life-threatening condition that occurs due to a dysregulated host response to infection. Recent data demonstrate that patients with sepsis have a significantly higher readmission risk than other common conditions, such as heart failure, pneumonia and myocardial infarction and associated economic burden. Prior studies have demonstrated an association between a patient's physical activity levels and readmission risk.

Predicting Ambulatory Capacity in Parkinson's Disease to Analyze Progression, Biomarkers, and Trial Design.

Background: In Parkinson's disease (PD), gait and balance is impaired, relatively resistant to available treatment and associated with falls and disability. Predictive models of ambulatory progression could enhance understanding of gait/balance disturbances and aid in trial design.

Objectives: To predict trajectories of ambulatory abilities from baseline clinical data in early PD, relate trajectories to clinical milestones, compare biomarkers, and evaluate trajectories for enrichment of clinical trials.

delivery of miRNA induces epigenetic alterations and corrects pulmonary pathology in congenital diaphragmatic hernia.

Structural fetal diseases, such as congenital diaphragmatic hernia (CDH) can be diagnosed prenatally. Neonates with CDH are healthy as gas exchange is managed by the placenta, but impaired lung function results in critical illness from the time a baby takes its first breath. MicroRNA (miR) 200b and its downstream targets in the TGF-β pathway are critically involved in lung branching morphogenesis.

Intra-amniotic Injection of Poly(lactic-co-glycolic Acid) Microparticles Loaded with Growth Factor: Effect on Tissue Coverage and Cellular Apoptosis in the Rat Model of Myelomeningocele.

Background: Myelomeningocele (MMC) is a devastating congenital neurologic disorder that can lead to lifelong morbidity and has limited treatment options. This study investigates the use of poly(lactic-co-glycolic acid) (PLGA) microparticles (MPs) loaded with fibroblast growth factor (FGF) as a platform for in utero treatment of MMC.

Study Design: Intra-amniotic injections of PLGA MPs were performed on gestational day 17 (E17) in all-trans retinoic acid-induced MMC rat dams.

A Smartphone Application as an Exploratory Endpoint in a Phase 3 Parkinson's Disease Clinical Trial: A Pilot Study.

Background: Smartphones can generate objective measures of Parkinson's disease (PD) and supplement traditional in-person rating scales. However, smartphone use in clinical trials has been limited.

Objective: This study aimed to determine the feasibility of introducing a smartphone research application into a PD clinical trial and to evaluate the resulting measures.

1-year cost-utility analysis of prostate artery embolization (PAE) versus transurethral resection of the prostate (TURP) in benign prostatic hyperplasia (BPH).

Objective: To determine whether prostate artery embolization (PAE) is a cost-effective alternative to transurethral resection of the prostate (TURP) in the management of benign prostate hyperplasia (BPH) after 1-year follow-up.

Design Setting And Main Outcome Measures: A retrospective cost-utility analysis over a 12-month time period was conducted to compare the two interventions from a National Health Service perspective. Effectiveness was measured as quality-adjusted life years (QALYs) derived from data collected during the observational UK Register of Prostate Embolisation (UK-ROPE) Study.

Diffusion weighted imaging as a biomarker of retinoic acid induced myelomeningocele.

Neural tube defects are a common congenital anomaly involving incomplete closure of the spinal cord. Myelomeningocele (MMC) is a severe form in which there is complete exposure of neural tissue with a lack of skin, soft tissue, or bony covering to protect the spinal cord. The all-trans retinoic acid (ATRA) induced rat model of (MMC) is a reproducible, cost-effective means of studying this disease; however, there are limited modalities to objectively quantify disease severity, or potential benefits from experimental therapies.

A narrative review of in utero gene therapy: advances, challenges, and future considerations.

The field of gene therapy (IUGT) represents a crossroad of technologic advancements and medical ethical boundaries. Several strategies have been developed for IUGT focusing on either modifying endogenous genes, replacing missing genes, or modifying gene transcription products. The list of candidate diseases such as hemoglobinopathies, cystic fibrosis, lysosomal storage disorders continues to grow with new strategies being developed as our understanding of their respective underlying molecular pathogenesis increases.

Pre-existing chronic physical morbidity and excess mortality in people with schizophrenia: a population-based cohort study.

Purpose: Schizophrenia is associated with increased premature mortality and physical morbidity. This study aimed to examine prevalence of pre-existing chronic physical diseases, and association between physical multimorbidity burden and mortality rates among patients with newly diagnosed schizophrenia.

Methods: This population-based cohort study investigated patients with first-recorded diagnosis of schizophrenia between January 2006 and December 2016, using territory-wide medical-record database of public healthcare service in Hong Kong.

Excess mortality and life-years lost in people with bipolar disorder: an 11-year population-based cohort study.

Aims: Bipolar disorder is associated with premature mortality, but evidence is mostly derived from Western countries. There has been no research evaluating shortened lifespan in bipolar disorder using life-years lost (LYLs), which is a recently developed mortality metric taking into account illness onset for life expectancy estimation. The current study aimed to examine the extent of premature mortality in bipolar disorder patients relative to the general population in Hong Kong (HK) in terms of standardised mortality ratio (SMR) and excess LYLs, and changes of mortality rate over time.

Laparoscopy is increasingly used for pediatric inguinal hernia repair.

Introduction: Inguinal hernia repairs (IHR) are commonly performed by pediatric surgeons in the United States. The operative approach depends on surgeon preference with no definitive prospective studies comparing laparoscopic inguinal hernia repair (LIHR) versus traditional inguinal hernia repair (TIHR). We aim to assess current practice, hypothesizing that laparoscopy is increasingly used for pediatric IHR.

Data Sources: Eligible studies published until June 2020 were retrieved from MEDLINE, Embase, Cochrane Central Register of Controlled Trials, EBSCO CINAHL, Web of Science, and ProQuest.

Study Eligibility Criteria: Studies must have been: (1) published in English in a peer-reviewed journal or in ProQuest, (2) available in full text, (3) contained a qualitative component, and (4) focused on expectant parents' experiences of tertiary, coordinated, multidisciplinary prenatal diagnosis and care related to a fetal anomaly.

Nanoparticles for delivery of agents to fetal lungs.

Fetal treatment of congenital lung disease, such as cystic fibrosis, surfactant protein syndromes, and congenital diaphragmatic hernia, has been made possible by improvements in prenatal diagnostic and interventional technology. Delivery of therapeutic agents to fetal lungs in nanoparticles improves cellular uptake. The efficacy and safety of nanoparticle-based fetal lung therapy depends on targeting of necessary cell populations.

Excess Mortality and Life-Years Lost in People With Schizophrenia and Other Non-affective Psychoses: An 11-Year Population-Based Cohort Study.

Psychotic disorders are associated with premature mortality, but research was primarily based on Western countries and rarely examined non-affective psychoses other than schizophrenia (ONAP). This population-based cohort study investigated excess mortality in 46 896 schizophrenia and 20 651 ONAP patients between January 2006 and December 2016 in Hong Kong (HK), by estimating all-cause and cause-specific standardized mortality ratios (SMRs), and life-years lost (LYLs), a recently developed, more precise reduced life expectancy measure taking into account the illness onset (age at first-recorded diagnosis). Changes in mortality metrics over the study period were assessed.

Closing the gap in care of blunt solid organ injury in children.

Introduction: Cross-sectional data of pediatric blunt solid organ injury demonstrates higher rates of nonoperative management and shorter lengths of stay (LOSs) in pediatric trauma centers (PTCs) versus adult trauma centers (ATCs) or dual trauma centers (DTCs). Recent iterations of guidelines (McVay 2008, J Pediatr Surg 2008;43(6):1072-1076 J Trauma Acute Care Surg 2015;79(4):683-693) have emphasized physiologic parameters rather than injury grade in clinical decision making, improving resource allocation and decreasing LOS. We sought to evaluate how these guidelines have influenced care.

Mortality in patients with schizophrenia admitted for incident ischemic stroke: A population-based cohort study.

Evidence shows that schizophrenia is associated with increased incidence of stroke. However, relationship between schizophrenia and short-term mortality risk is understudied, and mixed findings were observed. In this retrospective population-based cohort study, we identified individuals admitted for incident ischemic stroke between 2006 and 2016 using a territory-wide electronic medical record database of public healthcare system in Hong Kong to examine 30-day and 1-year mortality rates in 817 schizophrenia patients compared with 8170 patients without psychotic disorder (10:1 matched to schizophrenia patients on demographics, treatment sites and calendar-period for index admission).
