Background: Studies have shown a bidirectional relationship between asthma and obstructive sleep apnea (OSA). However, there is a paucity of national-level data evaluating the impact of OSA on hospital outcomes in pediatric hospitalizations for asthma.

Methods: We analyzed the National Inpatient Sample and Kids Inpatient Database to include all pediatric hospitalizations with a primary diagnosis of asthma between 2003-2016.

While Brugada syndrome (BrS) is well described in adults and older children, presentation of BrS within the first 12 months of life is rare and therefore poorly characterized. We report a 7-year-old male with a malignant BrS phenotype with onset at 8 months of age, leading to multiple ventricular tachycardia (VT) and ventricular fibrillation (VF) related cardiac arrests and ultimately his death. The report is supplemented by a comprehensive review of existing literature on infantile-onset BrS and unique features in this population are discussed.

Background: Patients with chronic pancreatitis (CP) often have a debilitating clinical course characterized by high disease burden, and poor quality of life and these factors adversely affect mental health. However, there is paucity of literature on the prevalence and impact of psychiatric disorders on hospitalized pediatric patients with CP.

Method: ology: We analyzed the Kids Inpatient Database, and National Inpatient Sample, between 2003 and 2019 and included patients up to 21 years of age.

Background: Adults with inflammatory bowel disease (IBD) are at increased risk of developing cytomegalovirus (CMV) colitis, which is associated with adverse outcomes. Similar studies in pediatric IBD patients are lacking.

Methods: We analyzed non-overlapping years of National Inpatient Sample (NIS) and Kids Inpatient Database (KID) between 2003 and 2016.

Purpose: The incidence and prevalence of inflammatory bowel disease (IBD) are increasing along with an increasing number of patients with comorbid conditions like psychiatric and behavioral disorders, which are independent predictors of quality of life.

Methods: Non-overlapping years (2003-2016) of National Inpatient Sample and Kids Inpatient Database were analyzed to include all IBD-related hospitalizations of patients less than 21 years of age. Patients were analyzed for a concomitant diagnosis of psychiatric/behavioral disorders and were compared with IBD patients without psychiatric/behavioral disorder diagnoses for outcome variables: IBD severity, length of stay and inflation-adjusted hospitalization charges.

Background: Pediatric severe sepsis (PSS) is associated with increased mortality, and acute kidney injury (AKI) is an independent risk factor of mortality in PSS. However, there is little data on impact of AKI on hospital outcomes in PSS.

Methods: We analyzed non-overlapping years of the Kids' Inpatient Database (KID) and National Inpatient Sample (NIS) database between 2003 and 2019 of all pediatric patients with severe sepsis between 1 and 18 years of age.

Adults with congenital heart disease (ACHD) are at risk of developing metabolic syndrome (MetS) at a younger age. We sought to obtain the prevalence of MetS in ACHD from a large population-based database in the United States. We conducted a retrospective cohort study of patients with ACHD in Explorys (IBM Inc.

Background: Cystic fibrosis-related liver disease (CFLD) is more prevalent in recent decades due to the increasing life expectancy of patients with cystic fibrosis (CF). There is paucity of population-level data on the impact of CFLD on hospital outcomes.

Methods: We interrogated nonoverlapping years (2003-2016) of the National Inpatient Sample and Kids' Inpatient Database to include all hospitalized patients <21 years of age with a primary diagnosis of CF within the United States.

Background: Patent Ductus Arteriosus (PDA) in premature neonates has been associated with comorbidities including chronic lung disease (CLD), and death. However, the treatment of PDA remains controversial. There have been several echocardiographic variables previously used to determine the hemodynamic significance of PDA but their utility in early prediction of clinical outcomes is not well studied.

Objective: To analyze the impact of acute pancreatitis on mortality and hospital outcomes among the pediatric population following hematopoietic stem cell transplantation (HSCT).

Study Design: We analyzed nationally representative, nonoverlapping years of the National Inpatient Sample and Kids Inpatient Database between 2003 and 2016, including all pediatric patients who had HSCT. Patients were divided into those with and without a diagnosis of acute pancreatitis and compared for demographics, clinical characteristics, comorbid conditions related to both HSCT and acute pancreatitis, and outcome measures such as in-hospital mortality and health care resource use (length of hospital stay and total hospitalization charges).

Purpose: Studies in adults have shown an increasing incidence of infection (CDI) in patients hospitalized with acute pancreatitis (AP). There is lack of epidemiological data on CDI and its impact on hospitalized pediatric patients with AP.

Methods: We analyzed the National Inpatient Sample and Kids' Inpatient Database between the years 2003 and 2016 and included all patients (age <21 years) with a primary diagnosis of AP using specific International Classification of Diseases codes.

Aim: To analyze the clinical characteristics, trends in hospitalization and health care resource utilization of pediatric patients with cyclical vomiting syndrome (CVS).

Methods: We analyzed the latest 5 Healthcare Cost and Utilization Project-Kids Inpatient Database (HCUP-KID) datasets including years 2003, 2006, 2009, 2012 and 2016 for patients aged 1-20 years with a primary diagnosis of CVS and were compared with Age/gender-matched controls for comorbidities, clinical outcomes, and healthcare resource utilization.

Results: A total of 12,396 CVS-related hospitalizations were analyzed.

Article Synopsis
  • The GBD 2019 study systematically estimated the global cancer burden, providing data on incidence, mortality, and disability to help address cancer worldwide.
  • In 2019, an estimated 23.6 million new cancer cases and 10 million cancer deaths occurred globally, marking significant increases in rates since 2010, with cancer becoming a leading cause of both death and disability-adjusted life years (DALYs).
  • The impact of cancer varied across sociodemographic index (SDI) quintiles, with higher SDI areas seeing more new cases, while middle SDI areas experienced more deaths and DALYs, highlighting disparities in cancer burden.

Congenital complete heart block is a potentially fatal complication that can occur in neonates whose mothers have autoimmune disorders; it has rarely been reported in the presence of Sjögren syndrome. Pacemaker implantation is recommended to treat rhythm abnormalities in these neonates. We report the case of a late-preterm infant with Sjögren-syndrome-antibody-induced complete heart block who underwent temporary bipolar epicardial pacing as a bridge to permanent pacemaker implantation.

Background: The incidence of acute pancreatitis (AP) in pediatric patients is rising with accompanying increased hospitalizations. Acute kidney injury (AKI) is associated with worse clinical outcomes in adults, and similar data in the pediatric age group is limited.

Methods: We analyzed non-overlapping years of National Inpatient Sample (NIS) and Kids Inpatient Database (KID) to include all patients less than 21 years old with primary diagnosis of AP between 2003 and 2016.
