Characteristics of pediatric inpatients with primary and secondary hypertension.

ABSTRACT:

Importance

Extensive population-based studies have explored the prevalence of primary hypertension (HTN) in children and adolescents. However, there is little published data on the characteristics of different types of pediatric HTN and the causes of secondary HTN.

Objective

To investigate the characteristics of different types of pediatric HTN and the causes of secondary HTN in a hospital setting.

Methods

The study cohort comprised pediatric inpatients (<18 years of age) discharged with a diagnosis of HTN from Beijing Children's Hospital during 2015-2020. Pediatric patients with HTN were allocated to secondary and primary HTN groups on the basis of comprehensive analyses of their diagnoses, family history of HTN, and findings on physical examination, as documented in their medical records. The Mann-Whitney U test, χ ² and Fisher's exact test were used to assess differences in characteristics of patients with different HTN types and causes of secondary HTN.

Results

Data of 1470 inpatients with HTN from 18 clinical departments were included in the analysis. Among them, 458 (31.2%) had primary HTN, and 1012 (68.8%) had secondary HTN. Compared with patients had primary HTN, children with secondary HTN were younger and had lower body mass indexes and longer lengths of stay. Moreover, children with primary HTN had mostly been managed by the Endocrinology and Cardiology Departments, 75.8% of them having obesity-related comorbidities. In contrast, most patients with secondary HTN had been managed by the Nephrology Department, renal diseases being the leading cause of their HTN (46.3%).

Interpretation

Secondary HTN is more common than primary HTN in pediatric clinical settings, renal diseases being the leading cause of secondary HTN.

Project description:BackgroundThe children infected with the Omicron variant of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) are at risk of progressing to severe disease. Clinical characteristics treatment measures and prognosis of these special age group of patients have not been completely understood which necessitate more researches. This study sought to analyze the clinical characteristics of children infected with the Omicron variant to provide evidences for the prevention, diagnosis and treatment of the Omicron variant infection in children.MethodsThe subjects of this study included children hospitalized for the Omicron variant at Tianjin Binhai Hospital in November 2022. The data were collected from the electronic medical record system, and the clinical characteristics of the children were analyzed. The primary endpoints included the clinical presentation, laboratory tests, virological characteristics, treatment regimen, and clinical prognosis of the patients.ResultsA total of 49 patients were enrolled, of whom 32 (65.3%) were male. The patients had a median age of 10 (interquartile range, 6-11) years, and 34.7% of the patients received 2 or more coronavirus disease 2019 (COVID-19) vaccines. The main clinical manifestations of the patients were fever (79.6%) and cough (24.5%), with a maximum temperature of 42 ℃ and a median temperature of 39 (interquartile range, 38.4-39) ℃. The proportions of neutrophils and C-reactive protein were elevated by 50.0% and 25.0%, respectively. The total percentages of white blood cells and thrombocytopenia were 12.5% and 6.3%, respectively. D-dimer was examined in 6 cases, and was elevated to 1.77 μg/mL in 1 case (16.7%), and normal in 5 cases. The liver function, kidney function, and coagulation of 9 (100%) patients were all normal. After the anti-virus, anti-inflammatory response, antipyretic, and traditional Chinese medicine treatments, all the children were cured and discharged from the hospital. There were no severe cases.ConclusionsThe main manifestations of children infected with the SARS-CoV-2 Omicron variant were fever and cough. Some children had a high fever, nasal congestion, runny nose, gastrointestinal symptoms, and rash. A proportion of 12.5% of patients have a white blood cell count less than 4×109/L, and 6.3% have thrombocytopenia. The prognosis of the child was favorable after treatment with antiviral, antipyretic, and traditional Chinese medicine.

Project description:BackgroundUK "Pathway" teams offer specialist hospital care coordination for people experiencing homelessness. Emergency healthcare use is high among homeless people, yet "homelessness" is not routinely coded in National Health Service (NHS) data. Pathway team records provide an opportunity to assess patterns in admissions and outcomes for inpatients identified as homeless.MethodsRetrospective analysis of patients referred to "Pathway" homelessness teams in seven UK hospitals to explore the patterns of hospital admission, morbidity, secondary healthcare utilisation and housing status. Each patient was individually identified as experiencing homelessness. Within a six-month period, demographic data, reason for admission, morbidity, mortality and secondary care hospital usage 120-days before and 120-days after the index admission was collected.ResultsA total of 1009 patients were referred, resulting in 1135 admissions. Most admissions had an acute physical health need (94.9%). Co-morbid mental illness and/or substance misuse was common (55.7%). Reasons for admission included mental and behavioral disorders (overdose, alcohol withdrawal or depression, 28.3%), external causes of morbidity and mortality (assault or trauma, 18.7%), and injury, poisoning and external causes (head injury, falls and fractures, 12.4%). Unplanned Emergency Department attendances reduced after index admission and unplanned hospital admissions increased slightly. Planned admissions doubled and total bed days increased. Housing status was maintained or improved for over 60% of inpatients upon discharge. Within 12 months of index admission, 50 patients (5%) died, 15 deaths (30%) occurred during the index admission.ConclusionsDisengagement with health services is common among homeless people. Many deaths are due to treatable medical conditions (heart disease, pneumonia, cancer). Observed increases in planned admissions suggests intervention from Pathway teams facilitates necessary investigations and treatment for homeless people. Equity, parity of care, and value should be inbuilt interventions for inclusion health groups and evaluations need to move beyond simply seeking cost reductions.
