ADHD and Atomoxetine (ATX)

  • ADHD - attention deficit hyperactivity disorder
    • Symptoms: inattention, hyperactivity, impulsivity
    • High-level impacts on an individual’s academic performance and personal life, relationships, and daily lifestyle
  • Atomoxetine - drug treatment for ADHD
    • Broken down by CYP2D6, a drug-metabolizing enzyme
    • Effective as a non-stimulant treatment for ADHD

Background: ATX and Metabolism

5

  • Neurons (nerve cells) send messages in the body using neurotransmitters like norepinephrine (NE)
  • ATX helps people with ADHD by blocking the reuptake of NE too quickly back into the nerve that sent it
    • Lets NE do its job longer and better
  • Enzymes break down our food, drugs, or chemicals into pieces called metabolites
  • This means the way ATX works in different people could correlate to different metabolite levels

6 of 68

Precision Medicine for ATX treatment

    • Not everyone responds to ATX the same way or at all
      • Some patients struggle with side-effects
      • For some ATX does nothing to ADHD
  • One goal of CMH is Precision Medicine
  • Precision Medicine allows for patients to be able to receive precise and specialized treatments
  • This study aims to investigate if we can predict whether a patient will respond to ATX or not by looking at their metabolite before giving them the medicine

Change in Metabolites from Baseline to 6 Weeks Associated with ATX Response

  • 2 metabolites were found to be related to response status:
    • Xanthurenate and Kynine
  •  None of these metabolites were found to differ by CYP2D6 status

11

Association of 6 Week ATX Drug Metabolites with Response

  • No significant differences in drug metabolite levels by responder status found 
  • Metabolites measured: 
    • 4-hydroxy atomoxetine
    • 4-hydroxy n-desmethyl atomoxetine
    • N-desmethyl atomoxetine

Discussion & Conclusions

  • Results were consistent with our hypothesis that metabolite levels, and changes in those levels weeks after ATX treatment, do differ between responders and non-responders
  • 3 baseline metabolites differed: Xanthurenate, Indolepropionate, 8-methoxykynurenate
  • 2 changes in metabolites differed: (Xanthurenate, Kynurenine) also differed between responders and non-responders 
  • None of these metabolite or changes differed by CYP2D6 status
  • No difference was found between responders and non-responders in their levels of the three ATX drug metabolites we measured
  • Further Research in a larger study is needed

Introduction

  • Seeing increase in missed appointments
  • Missed Appointment = missing appointment with no notification
  • Causes = miss out on important appointments and opens up slots for hospital schedule – annual loss of profit

17

18 of 68

Introduction

To prevent missed opportunities, we researched some reasons why a person may miss their appointment. Understanding these reasons can help healthcare providers implement strategies to improve attendance (NIH 2020).

  • Forgot the appointment – 26%
  • Other reasons ( illness, travel, family emergency) – 23%
  • Transportation issues – 6%
  • Work-related conflicts – 1.7%

18

19 of 68

Impacts of Missed Appointments:

    • Children miss necessary care, leading to worsening health conditions.
    • Open appointment slots are created, which could have been utilized by other patients.
    • Loss of work for physicians due to unfilled schedules.
    • Annual financial loss of approximately $22,000 per clinic for healthcare facilities (Lee 2025).

19

20 of 68

Measures Taken by Children's Mercy:

    • Implementing reminder calls to patients about upcoming appointments.
      • Calls made by Contact Center and Patient Access reps
    • Inquiring about patients' intentions to attend their scheduled appointments.

20

21 of 68

Methodology

  • High-risk patients: missed 30% or more of their previous appointments

21

Contact Center & Patient Access staff contact guardians of high-risk patients with appointments scheduled 1 week out

Family answers call and confirms, reschedules, or cancels appt

Family does not answer – voicemail is left if possible

  • Used a two-proportion z-test to test for a significant difference
    • p-value: 0.000
  • Conclusion: Patients are significantly more likely to attend their appointment when we leave a voicemail compared to when we are unable to contact them
  • This indicates that leaving a voicemail is still more effective than no contact at all. Additionally, patients who have a disconnected phone or do not answer and don’t have a voicemail option are most likely to miss their appointments.

27 of 68

Conclusion

  • Patients are more likely to attend appointment if we remind the patient before the appointment.
    • People either show up or reschedule their appointment when they are contacted.
  • Our findings were significant because we verified the interventions we have in place are making a difference for high-risk patients at a 95% significance level

27

28 of 68

Recommendations

  • Run the significance tests again when more data is available
  • Utilize features in Epic’s app for scheduling, rescheduling, and reminders
  • Utilize Telehealth appointments
  • Give appointment cards for upcoming appointments when scheduled at the clinic
  • Attempt to get updated contact information
  • Hire more staff + set biweekly goals + rewards system (gift cards, luncheons, prizes)

CDH & Hearing Loss: What We Know!

  • Children with CDH are presumed to be at higher risk of hearing loss (HL)
  • The most common type of hearing loss in CDH patients is sensorineural hearing loss (SNHL), others are conductive and mixed.
  • Causes can be congenital or acquired

35

It is not studied whether there is discrepancy in the prevalence of hearing loss with age.

Known Risk Factors:

  • Ototoxic Medication
  • Extracorporeal Membrane Oxygenation (ECMO)
  • Inhaled Nitric Oxide (iNO)
  • Prolonged ventilation
  • Hypoxia
  • Low Birth Weight

36 of 68

Aim

Determine frequencies of hearing loss in children diagnosed with CDH at initial discharge and at follow-up assessments at 12 and 24 months of age.

Determine association of risk factors with failed hearing screen in CDH at discharge and at follow up visits.

Methodology

  • Retrospective cohort study conducted on infants w/ CDH in Level IV NICU

  • Data was collected from 2010-2020

  • 73 surviving infants until discharge, smaller cohort at follow up visits

  • Compared hearing screen results at discharge from NICU versus at follow up visits

    (Discharge > 12 Months > 24 Months)

37

38 of 68

Statistical Analysis

  • SPSS 30 software

  • Median and interquartile range (IQR) for continuous data due to non-normal distribution

  • Categorical data were presented as percentage

  • Fisher’s exact tests used to generate p-value comparing infants who undergo ECMO, use ototoxic medication, or use of iNO by hearing screen result at discharge and follow up visits.

  • Trend analysis for proportion was used to evaluate failed hearing screens for infants who had ECMO, ototoxic medications and iNO over time.

Discussion

  • Hearing loss rates increased from 5.5% at discharge to 32.1% at 12 months and 34% at 24 months�
  • In our cohort, ECMO, iNO and ototoxic treatment was not strongly linked to hearing loss although increased linear trend in failed hearing screen at discharge and subsequent follow up visits noted with iNO and ototoxic medications.

Shortcomings:

    • Study had a small sample size of 73 and no control group for comparison
    • The type of hearing loss (sensorineural vs. conductive) was not determined; a more general study on hearing loss

46

47 of 68

Conclusion

  • Hearing loss in CDH patients can be progressive and delayed
  • Results showed no significance in medical interventions to HL for CDH cases
  • Highlights the necessity for routine audiology follow-ups, especially in the first 2 years
  • Early screenings alone are not reliable indicators of long-term hearing outcomes
  • Future studies should focus on larger groups, risk factors, and long-term outcomes
  • No other studies on CDH and hearing loss have collected data in separate intervals in correlation to risk factors making this study unique

      PBMC Extraction and scRNA Sequencing

    • PBMCs were isolated using the SepMate protocol
    • Single- Cell sequencing methods was used to determine cell population in single cell gene expression 

Statistical Analysis

    • Cell proportions calculated in Excel, Wilcoxon rank-sum test used to compare immune cell proportions across ACE categories, p < 0.05 
    • Used a generalized linear model to identify differentially expressed genes (DEGs) between high vs. low stress groups
    • Adjusted p-values using Benjamini-Hochberg false discovery rate (FDR)
    • FDR < 0.05 were considered significant
