About

Newborn Physique

This application helps healthcare professionals quickly assess a newborn's physical development based on weight, height, and head circumference relative to gestational age. It calculates z-scores and percentiles, and identifies infants considered Small for Gestational Age (SGA). The app utilizes data from The Journal of the Japan Pediatric Society for its assessments.

Highlights
  • Assess newborn physique
  • Calculate z-scores and percentiles
  • Identify SGA infants
  • Utilizes pediatric society data
  • Customizable display options

Newborn Physique is an application to assess the newborn's physique such as weight, height and head circumference for gestational age. You can quickly evaluate a newborn's physique on iOS device. It is very convenient to use in the field of neonatal care. - Displays the z-score (Standard Deviation value) and Percentile of weight, height and head circumference. - Displays "SGA" if weight and height were below 10 percentile . - You can set the default value of gestational age, show SGA or not, and show percentile or not. This app uses the data in the article of The Journal of the Japan Pediatric Society.

糸球体濾過量(GFR)算出のゴールドスタンダードであるイヌリンクリアランスは,特に小児では検査手技が煩雑です.日常診療で容易に小児の腎機能を評価するためにこれまでもGFR推算式(eGFR)が使われてきました. しかし,これまで汎用された旧Schwartz推算式は,血清クレアチニン(s-Cr)測定が現在日本で使用されている酵素法ではなくJaffé 法であるという問題があり,新Schwartz推算式は酵素法に改められましたが筋肉量の急激に増加する思春期を含めた1歳~16歳で共通の係数を使用するという問題がありました.また民族による腎機能や筋肉量の違いもあります.そこで,日本人固有の2つのeGFR作成をおこないました. I. 日本人小児のs-Crを利用したeGFR 2歳~18歳については,男女に分けて,下記のように身長から血清クレアチニン基準値(ref Cr)を求めます.その論文は以下に示しました. 男児については身長をHt (m)とすると,  ref Cr =-1.259Ht5+7.815Ht4-18.57Ht3+21.39Ht2-11.71Ht+2.628 女児については身長をHt (m)とすると,  ref Cr =-4.536Ht5+27.16Ht4-63.47Ht3+72.43Ht2-40.06Ht+8.778 その計算をした上で,  eGFR(ml/min/1.73m2) = 110.2×(ref Cr / s-Cr) +2.93 によりeGFRが求められます. 残念ながら,2歳未満ではs-Crを利用したeGFRを使うことができません. II. 日本人小児のcysCを利用したeGFR cysCを利用したeGFRを作成した.1ヶ月~18歳について以下の式でeGFRが求められます.その論文は以下に示しました. eGFR (mL/min/1.73 m2) = 104.1 ×1/serum cysC (mg/L) - 7.80 また,求めたGFRが正常なのか異常なのかを知るために,GFRの基準値が必要です.以前に日本人小児のs-CrやcysCの基準値を作成したときのデータを推算式に入れることでGFR基準値表を作成しました.2歳以上18歳以下はs-Crを利用したeGFRで,3ケ月以上2歳未満はcysCを利用したeGFRで計算したもので,3か月未満の基準値はありません. 腎機能が正常の50%未満ならば赤字のアラート,75%未満ならば黄字のアラートが出るようになっています.このアプリケーションが活用され,小児CKD患者が早期発見・早期治療されて,その子たちの幸せに繋がればと思います. 論文 1.Uemura O, Nagai T, Ishikura K, et al: Creatinine-based equation to estimate the glomerular filtration rate in Japanese children and adolescents with chronic kidney disease.

Verdict

The call

The clearest difference is price: 小児CKD at Free against Newborn Physique's $0.99. 小児CKD also leads on iOS requirement (9.2 vs 17.0). Newborn Physique's advantage is update cadence (every 3 weeks vs every 2 months). On ads, in-app purchases and device support there is nothing between them.
