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.

Mortality rates in people with first diagnosis of schizophrenia-spectrum disorders: A 5-year population-based cohort study.

Objective: Schizophrenia-spectrum disorder (SSD) is associated with increased premature death, with emerging data suggesting early illness course as a high-risk period for excess mortality. This study aimed to examine mortality rate in patients with incident SSD and differential mortality risk between inpatient-diagnosed and outpatient-diagnosed subsamples within 5 years of first diagnosis.

Method: This population-based cohort study identified 8826 patients aged 18-39 years receiving first-recorded SSD diagnosis upon service entry, comprising 3877 inpatient-diagnosed and 4949 outpatient-diagnosed patients, between 2006 and 2012 in Hong Kong using a territory-wide medical record database of public health care services.

Establishing an Association between Polycystic Ovarian Syndrome and Pilonidal Disease in Adolescent Females.

Study Objective: We sought to determine whether pilonidal disease (PD) is associated with polycystic ovarian syndrome (PCOS) in adolescent females.

Design: Retrospective cohort study SETTING: Urban tertiary children's hospital PARTICIPANTS: All girls aged 12 to 21 who received a diagnosis of PD and/or PCOS from 2012 to 2019 INTERVENTIONS: Treatment for PCOS and PD MAIN OUTCOME MEASURES: The variables analyzed included age, race/ethnicity, body mass index, age at menarche, tobacco use, payer status, treatment of PCOS and PD, and serum markers of hyperandrogenism and metabolic syndrome.

Results: During the study period, 100,043 patients presented to an urban tertiary medical center.

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.

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.

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.

The parental journey of fetal care: a systematic review and metasynthesis.

Objective: This study aimed to synthesize the qualitative literature on parental experiences of fetal care to reflect events that happened across the continuum of care and to better understand parents' positive and negative experiences with care delivery.

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).
