One way to extract the first value of that loop:

Code:
find "$dir" -maxdepth 1 -mindepth 1 -type d -printf '%T+\t%P\0' | sort -rz > /tmp/$$
while read -r -d $'\t' time && read -r -d '' filename
do
    printf "The oldest folder is $filename, created on $time and analysis done using v1.4 by $USER at $(date "+%D %r")\n" >> /home/cmccabe/medex.logs/folder.log
    awk -v FL="$filename" '
         FNR == 1 {filenum++}
         filenum==1 && index($0, FL) { 
              match($0, "_0*([0-9]+)/")
              FNUM=substr($0,RSTART+1,RLENGTH-2)
              gsub(/^0+/,"", FNUM)
          }
          filenum==2 && $0 ~ FNUM".pdf$"' /home/cmccabe/s5_files/downloads/list /home/cmccabe/s5_files/pdf/pdf > /home/cmccabe/s5_files/pdf/output
    break
done < /tmp/$$

read filename < /tmp/$$
rm -f /tmp/$$

If your data is formatted differently than you showed, it won't work.

SYNOPSIS

       cachefslog [-f logfile | -h]  cachefs_mount_point

DESCRIPTION

       The  cachefslog	command displays where CacheFS statistics are being logged. Optionally, it sets where CacheFS statistics are being logged,
       or it halts logging for a cache specified by cachefs_mount_point. The cachefs_mount_point argument is a mount point of a cache file system.
       All file systems cached under the same cache as cachefs_mount_point will be logged.

OPTIONS

       The following options are supported. You must be super-user to use the -f and -h options.

       -f logfile      Specify the log file to be used.

       -h	       Halt logging.

EXAMPLES

       Example 1: Checking the Logging of a directory.

       The example below checks if the directory /home/sam is being logged:

       example% cachefslog /home/sam
       not logged: /home/sam

       Example 2: Changing the logfile.

       The example below changes the logfile of  /home/sam to /var/tmp/samlog:

       example# cachefslog -f /var/tmp/samlog /home/sam
       /var/tmp/samlog: /home/sam

       Example 3: Verifying the change of a logfile.

       The example below verifies the change of the previous example:

       example% cachefslog /home/sam
       /var/tmp/samlog: /home/sam

       Example 4: Halting the logging of a directory.

       The example below halts logging for the /home/sam directory:

       example# cachefslog -h /home/sam
       not logged: /home/sam
