鎌状赤血球症における末梢動脈眼圧測定と神経認知
この研究では、あらゆる遺伝子型の鎌状赤血球症と診断された参加者(12~18歳)の睡眠呼吸障害と睡眠の質を調査します。 遠隔末梢動脈眼圧測定法(PAT)とアンケートを利用して、睡眠の困難さを評価します。 PAT 評価は参加者の自宅で遠隔的に行われます。
神経認知、行動、神経画像の評価は、通常の診療と同じ日に行われます。
第一目的:
鎌状赤血球症と診断された小児(12~18歳)において、年齢、遺伝子型、社会的脆弱性を調整しながら、夜間のオキシヘモグロビン飽和度(SpO2)と神経認知機能(作業記憶および言語理解)との関係を評価します。
二次的な目的:
鎌状赤血球症と診断された小児 (12 ~ 18 歳) で睡眠呼吸障害がある場合とない場合で、年齢をコントロールした上で、白質の完全性、サイレント脳梗塞、神経炎症、機能的接続性の違いを評価します。
鎌状赤血球症と診断された小児 (12 ~ 18 歳) で、睡眠呼吸障害がある場合とない場合で、年齢をコントロールした上で、自己報告と介護者の報告による気分と痛みの重症度の違いを評価します。
探索的な目的:
鎌状赤血球症と診断され、年齢、遺伝子型、社会的脆弱性をコントロールしている小児(12~18歳)の夜間オキシヘモグロビン飽和度(SpO2)と神経認知機能(注意力、処理速度、言語記憶、視覚記憶、運動器用さ)との関係を調査します。 。
鎌状赤血球症と診断された子供 (12 ~ 18 歳) に対する超ポータブル リング オキシメーター (BodimetricsCircul+ Ring) の実現可能性を評価します。
鎌状赤血球症と診断された小児 (12 ~ 18 歳) を対象に、Circul+Ring と WatchPAT の一致性を評価します。

メジャーの説明 |

Evaluate the relationship between nocturnal oxyhemoglobin saturation (SpO2) and neurocognitive functioning (working memory and verbal comprehension) in individuals (ages 12-25) diagnosed with sickle cell disease.
時間枠:Baseline remote sleep assessment over 3 days followed by in-clinic assessment.
|
A linear regression model will be used to assess the relationship between SpO2 and neurocognitive functioning after adjusting for age, genotype, and social vulnerability.

|
Assess differences in white matter integrity among individuals (ages 12-25) diagnosed with sickle cell disease with and without sleep disordered breathing.
時間枠:Baseline remote sleep assessment over 3 days followed by in-clinic assessment.
|
This study will measure resting-state BOLD signal in SCD patients after assessing nocturnal oxyhemoglobin saturation.
The primary endpoint is the whole brain BOLD response and functional connectivity among brain regions within the default mode, fronto-parietal, executive control, salience, sensorimotor, and other resting state networks.
Then we will compare differences in white matter integrity based on the structural connectivity connectome for the working memory network, silent cerebral infarcts, neuroinflammation, and functional connectivity among individuals with and without sleep disordered breathing.

Assess differences in self- and caregiver-reported mood and pain severity among individuals (ages 12-25) diagnosed with sickle cell disease with and without sleep disordered breathing after controlling for age.
時間枠:Baseline remote sleep assessment over 3 days followed by in-clinic assessment.
|
The general linear regression model is then used to assess the relationship of functional connectivity and to assess the relationship of self- and caregiver-reported mood and pain severity with sleep disordered breathing with controlling for age in the model.
As a secondary analysis, we will also associate continuous obstructive and central AHI with functional connectivity and self- and caregiver-reported mood and pain severity using linear regression model with adjusting for age.

Assess the feasibility of an ultraportable ring oximeter (BodimetricsCircul+ Ring) in individuals (ages 12-25) diagnosed with sickle cell disease.
時間枠:Baseline remote sleep assessment over 3 days followed by in-clinic assessment.
|
Feasibility of the Circul+Ring equipment will be defined as more than 50% of participants wearing Circul+Ring for at least one night's sleep.
There is no power calculation needed for this feasibility objective.
However, 55 participants give 92% power to detect a 20% difference at an assumed 70% of participants who will wear the ring for at least one night's sleep, with a significance level of 0.05 based on a one-sided test.
The number of hours worn for the WatchPAT and Circul+Ring will be compared using Wilcoxon rank sum test.
Descriptive statistics will be used to summarize the two-question survey.

|
Assess the concordance between the Circul+Ring with the WatchPAT in individuals (ages 12-25) diagnosed with sickle cell disease.
時間枠:Baseline remote sleep assessment over 3 days followed by in-clinic assessment.
|
To evaluate concordance, the nocturnal SpO2 obtained using the WatchPAT and a Circul+ Ring will be plotted against each other, and Pearson/Spearman correlations will be used to examine their relationship.
The Bland-Altman method will be used to investigate the variability between the two measurements using the WatchPAT and Circul+ Ring.
Lin's concordance correlation coefficient will be determined to demonstrate the level of agreement.
