「CADi2」は認知症早期発見のための検査アプリです。Cognitive Assessment for Dementia, iOS versionの頭文字をとりCADiです。住民健診等におけるマススクリーニングでの使用を想定しています。CADi2ではCADiから2つの問題の入れ替え及び問題順序の変更を実施し,認知症検出精度を向上させています。 ※重要:CADi2は認知症の可能性のある方を検出するのが目的であり、この検査における低得点が直ちに認知症を意味するものではありません。同様に高得点が認知症でないことを確証するものでもありません。結果に不安がある場合は、かかりつけ医等にご相談ください。 【主な機能】 認知症早期発見のための一次スクリーニング用検査です。 ◆CADi検査項目の構成 本検査は10個の項目で構成されます。 1.即時再認、2.長期記憶、3.逆唱、4.見当識(月)、5.見当識(曜日)、6.計算、7.直方体回転、8.順列作成A、9.順列作成B、10.遅延再認。 1項目1得点の10点満点で評価されます。また、各設問を回答するのにかかった時間も記録されます。 ◆必須装置 CADiは音声で問題が提示されるため、ヘッドフォンを必要とします。ヘッドフォンは密閉型が推奨されます。検査者の声が聞こえなくなるため、ノイズキャンセラーのついたヘッドフォンの使用は避けてください。 ◆使用条件 CADiは検査者と被験者が一対一で行うことを想定しています。事前に内容を把握した検査者が被験者につき、被験者を補助してください。答えを教える以外の補助(分かりやすく言い直してあげる等)は問題ありません。被験者が単独でこの検査を行った場合、その結果はあまり信頼できるものではありません。 ◆検査の流れ 検査は個人識別のためのID入力、ヘッドフォン装着、タッチ練習、練習問題2問、本問題10問、フィードバックの順に行います。音声と画面の指示に従ってください。 ◆評価 10点満点中6点以下が認知症を疑いますが、これは暫定的な基準です。 ◆データ管理 検査データはメールに添付して送信する方法と、iTunesに接続して取り出す方法が用意されています。また、iTunesからsqlite3形式のデータベースファイルが見えるようになって 【その他の機能】 ◆玉ころがしゲーム 認知機能維持のためのアプリとして、玉ころがしゲームが付属しています。非常に簡単な面から若者でも難しい面まで、全部で30面あります。このゲームもクリアするまでの時間等が記録されます。ご自由に活用ください。 【データの取扱】 検査データはクラウドに送信され保存されます。このデータは本アプリの検査性能の向上と機能開発ために活用され、それ以外の用途では利用されません。また、検査データは個人情報を含みません。 【開発と検証】 CADiシリーズは,島根大学医学部神経内科が株式会社テクノプロジェクト[http://www.tpj.co.jp]及び株式会社イーストバック[http://www.eastback.co.jp]の協力を得て開発を行いました。妥当性の検証は島根大学医学部付属病院においてアルツハイマー病患者を対象に行われました。CADi2は健常者とアルツハイマー病患者を感度0.85~0.96,特異度0.81~0.93の精度で識別可能でした(Onoda & Yamaguchi, 2014) [http://www.ncbi.nlm.nih.gov/pubmed/25310860]。すでに島根県内の幾つかの自治体における住民健診や,全国複数の脳ドック施設において認知症早期発見のため活用がなされています。 本アプリの機能は以下の研究成果に基づいて設計されています。 - 認知症マススクリーニングにおける iPad の活用:CADi の開発と検証 https://www.jstage.jst.go.jp/article/hbfr/34/3/34_331/_article/-char/ja/ - Revision of the Cognitive Assessment for Dementia, iPad Version (CADi2) https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0109931 - やる気スコアを用いた脳卒中後の意欲低下の評価 https://www.jstage.jst.go.jp/article/jstroke1979/20/3/20_3_318/_article/-char/ja

"MySOS" is an app that connects you and your family with medical care as you face health conditions and illnesses. By registering your own and your family’s health and medical records, it can facilitate communication with healthcare providers during consultations and sharing information among family members. You can record vitals such as blood pressure, blood sugar levels, and weight, as well as daily symptoms and medication records. Additionally, by linking with Mynaportal operated by the Digital Agency, you can easily register information about your medications, health checkup results, and medical expenses. Recommended for: • Those managing conditions like diabetes, hypertension, dyslipidemia, or hyperuricemia. • Individuals who already maintain records such as blood pressure logs or blood sugar diaries. • People looking to prevent conditions such as heart failure or chronic kidney disease (CKD). • Anyone who wants to manage their own health. • Those who wish to share health information with family members. • Individuals who want to manage the health of family members who don’t own a smartphone. Features of MySOS: ■ Recording and setting goals for vital signs important for health management and treatment You can record and manage vitals such as body temperature, blood pressure, heart rate, weight, body fat percentage, blood sugar levels, SpO2, and step count. It is also possible to link with health care apps pre-installed. The recorded data can be displayed in graph form. Additionally, you can set target values as agreed upon with your primary care physician or occupational health doctor. ■ Recording daily symptoms and actions like medication intake You can register daily symptoms (such as headaches or vomiting), wake-up and bedtime, and medication intake records. Mood and memos can also be recorded, providing support for accurately conveying your condition and symptoms to your doctor during consultations. ■ Registering medication information and alert functions You can register medications ranging from over-the-counter drugs to those prescribed by healthcare providers. Reminders can be set to prevent missed doses. ■ Recording through Mynaportal integration You can record information about your medications, medical expenses, specific health check-up results, and vaccination history through the Mynaportal managed by the Digital Agency. ■ Sharing records with family members You can share information on vitals like blood pressure, blood sugar levels, and weight, as well as medication and health checkup results among family members. Information for children and elderly who do not own the app can be recorded by proxy through a family account. Family accounts can be easily transferred using QR codes. ■ AED and Medical Facility Search You can check the locations of AEDs and hospitals on a map. ■ Basic Life Support Guide, Medical Emergency Guide(Adults and Children) and First Aid Guide • The Basic Life Support Guide supports you in assessing the situation and performing basic life support (BLS) until the ambulance arrives when you find someone experiencing a medical emergency. • Medical Emergency Guide(Adults and Children) assists parents of young children in determining how to respond to sudden illnesses during holidays or nighttime. It provides guidance on how to deal with different symptoms and when to seek emergency medical care. • The First Aid Guide provides instructions on initial care in cases of fractures, bleeding, convulsions, heatstroke, and more. It also offers tips on accident prevention. (Japanese Red Cross Society provided) ■ Feedback Please send requests or comments regarding the app via review or email.
