[PMID: 34239067 PMCID: PMC8265292 DOI: 10.1038/s41390-021-01606-3] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/30/2020] [Revised: 05/14/2021] [Accepted: 05/20/2021] [Indexed: 02/01/2023]
Abstract
BACKGROUND Children receiving home medical care need special attention to prevent unexpected death. The aim of this study was to clarify the factors contributing to death in children receiving home medical care from the child death review database. METHODS Children receiving home medical care were enrolled from the child death review database from 2014 to 2016 in Aichi prefecture, Japan, with a population of one million children. Types of medical care and factors contributing to death were examined. RESULTS Of the 631 children who died, 40 children (6%) were receiving home medical care (21: tracheostomy; 19: ventilator; 26: suctioning of naso-oral secretions; 19: oxygen inhalation; 32: tube feeding; 6: urethral catheterization; and 1: peritoneal dialysis). The death rate was 50 times that in the general population of children. Ten children had contributory factors that seemed to be preventable. In four children, the families could not replace the tracheostomy tubes during an accident. In three, oxygen saturation or ventilator alarms were not set appropriately. In two, an oxygen cylinder became empty. One child fell down from a seat in a car. CONCLUSIONS Improvement of devices and correct guidance to caregivers may reduce the death rate in children receiving home medical care. IMPACT Children receiving home medical care, such as tracheostomy care, mechanical ventilation, or tube feeding, need special attention to prevent unexpected death. In this population-based child death review, 6% of children received home medical care, and it was estimated that 1 of 100 children receiving home medical care died per year. One-quarter of the deaths could be preventable by caregiver education or development of devices.

Natural History of Leigh Syndrome: A Study of Disease Burden and Progression. Ann Neurol 2021; 91:117-130. [PMID: 34716721 PMCID: PMC9534328 DOI: 10.1002/ana.26260] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/31/2021] [Revised: 10/26/2021] [Accepted: 10/26/2021] [Indexed: 11/21/2022]
Abstract
Objective This observational cohort study aims to quantify disease burden over time, establish disease progression rates, and identify factors that may determine the disease course of Leigh syndrome. Methods Seventy‐two Leigh syndrome children who completed the Newcastle Paediatric Mitochondrial Disease Scale (NPMDS) at baseline at 3.7 years (interquartile range [IQR] = 2.0–7.6) and follow‐up assessments at 7.5 years (IQR = 3.7–11.0) in clinics were enrolled. Eighty‐two percent of this cohort had a confirmed genetic diagnosis, with pathogenic variants in the MT‐ATP6 and SURF1 genes being the most common cause. The total NPMDS scores denoted mild (0–14), moderate (15–25), and severe (>25) disease burden. Detailed clinical, neuroradiological, and molecular genetic findings were also analyzed. Results The median total NPMDS scores rose significantly (Z = −6.9, p < 0.001), and the percentage of children with severe disease burden doubled (22% → 42%) over 2.6 years of follow‐up. Poor function (especially mobility, self‐care, communication, feeding, and education) and extrapyramidal features contributed significantly to the disease burden (τb ≈ 0.45–0.68, p < 0.001). These children also deteriorated to wheelchair dependence (31% → 57%), exclusive enteral feeding (22% → 46%), and one‐to‐one assistance for self‐care (25% → 43%) during the study period. Twelve children (17%) died after their last NPMDS scores were recorded. These children had higher follow‐up NPMDS scores (disease burden; p < 0.001) and steeper increase in NPMDS score per annum (disease progression; p < 0.001). Other predictors of poor outcomes include SURF1 gene variants (p < 0.001) and bilateral caudate changes on neuroimaging (p < 0.01). Interpretation This study has objectively defined the disease burden and progression of Leigh syndrome. Our analysis has also uncovered potential influences on the trajectory of this neurodegenerative condition. ANN NEUROL 2022;91:117–130
