You could play with IEEEtran
to generate the similar looking document template. This is what I could get.
\documentclass{IEEEtran}
\usepackage{lipsum}
\title{Here goes my JTEHM Title}
\author{Author1, Author2, Author3 \\ Institute1, Address1\\ Institute2, Address2}
\begin{document}
\twocolumn[
\begin{@twocolumnfalse}
\maketitle
\end{@twocolumnfalse}
\begin{abstract}
~{\lipsum[1-1]}
\index{keyword1, keyword2, keyword3}
\end{abstract}
\bigskip]
\section{Introduction}
\lipsum[1-7]
\section{Conclusion}
\lipsum[1-1]
\end{document}
