Objectives: We examined the trends in the rate of Henoch-Schönlein purpura (HSP) hospitalizations and the associated resource use among children in the United States from 2006 through 2014.

Methods: Pediatric hospitalizations with HSP were identified by using , code 287.0 from the National Inpatient Sample. HSP hospitalization rate was calculated by using the US population as the denominator. Resource use was determined by length of stay (LOS) and hospital cost. We used linear regression for trend analysis.

Results: A total of 16 865 HSP hospitalizations were identified, and the HSP hospitalization rate varied by age, sex, and race. The overall HSP hospitalization rate was 2.4 per 100 000 children, and there was no trend during the study period. LOS remained stable at 2.8 days, but inflation-adjusted hospital cost increased from $2802.20 in 2006 to $3254.70 in 2014 ( < .001).

Conclusions: HSP hospitalization rate in the United States remained stable from 2006 to 2014. Despite no increase in LOS, inflation-adjusted hospital cost increased. Further studies are needed to identify the drivers of increased hospitalization cost and to develop cost-effective management strategies.

Endoplasmic reticulum stress (ERs) is implicated in antitumor immunity. However, the exact role of ERs in mediating the effects of dendritic cells (DCs) is not unclear. In this study, we explored the role of exosomes derived from ER-stressed hepatocellular carcinoma (HCC) cells in the antitumor effects of DCs and the precise underlying mechanism.

Background: The aim of this study was to characterize hereditary spastic paraplegias (HSP) patients' urodynamic profiles and development of bladder symptoms.

Methods: This is a multicentric retrospective study which included patients presenting with bladder disorders. We reviewed medical and urodynamic records in individuals with HSP and recorded age at onset of gait and bladder disorders, disability stage at the time of urodynamic assessment.

Diagnosing hereditary spastic paraplegia (HSP) in paediatric patients can be challenging, especially when there is no positive family history. Children are often initially misdiagnosed with cerebral palsy due to the gradual progression of the disease and non-specific neuroimaging findings, despite the absence of perinatal insult. This misdiagnosis can prevent timely prenatal diagnosis, limiting the ability to make informed decisions about the pregnancy and to plan early interventions.

Patients with Hereditary Spastic Paraplegia (HSP) report reduced quality of life (QoL) compared to the general population. Generic QoL measures do not address disease-specific aspects such as spasticity, access to specialty HSP clinics, and bladder symptoms. We designed and validated a HSP-specific QoL scale (HSPQoL), intended for use in standard clinical settings and clinical trials.

Protein-protein interactions (PPIs) form complex cellular networks fundamental to many key biological processes, including signal transduction, cell proliferation and DNA repair. In consequence, their perturbation is often associated with many human diseases. Targeting PPIs offers a promising approach in drug discovery and ongoing advancements in this field hold the potential to provide highly specific therapies for a wide range of complex diseases.
