AI Corner: Fun Fact: Run an Auto Transcript through an AI Fixer

 Otter.ai and other subscriptions services provide high quality "automatic transcripts" from audio files.   For example, I recently fed a five-hour government CMS web meeting through this service.

With ordinary conversations, Auto Transcript is pretty spot-on.   However, with detailed  technical material, it's more likely to make mistakes.

Here's a workaround.   Make the auto transcript of the public meeting (or youtube meeting) via a service like Otter.AI.   It will do the best it can, but it will never add or subtract words from what it attempts to transcribe.

THEN, as step two, feed the Auto Transcript into CHAT GPT (or another AI) and ask it to "fix" the Auto Transcript.   The result will be better, because the Chat GPT AI will feel able to make small changes for sense or common sense, and will probably improve sentence flow and paragraphing or headings.

Here's an example from a June 25, 2024, web-streamed CMS lab meeting on new test pricing policy.  Note, I've manually inserted test names that were unavailable in the audio file.

PROMPT: 

This is an Auto Transcript, which naturally has some errors or awkward grammar. 

 Please improve it, but make only minor changes for clarity and stay very close to the auto transcript.

Thank you. My name is Michelle Aldrich and I am the clinical lab laboratory director for Europeans transplant genomics. I'm here today to talk about the newly approved category one CPT code 815 6x for true graph kidney. Next slide please. This test is a gene expression profile to be used after kidney transplantation as a way to detect a subclinical rejection with the goal of improving long term outcomes of kidney transplantation and reducing the need to either go back on dialysis or have a second transplant the methodology is listed there. And the other alternative for this test is it will avoid the need for invasive and costly surveillance biopsies. Next slide. And so this slide lists the resources necessary to perform the test both from a reagent consumable equipment and a labor standpoint, as illustrated these resources are substantial. In addition, of course, there was heavy r&d involved in the development in many clinical studies that have been performed. To demonstrate the clinical validity and clinical utility of this assay. It is currently approved by modex under General LCD. Next slide please. So our crosswalk recommendation is to crosswalk to CPT code 81595, which is a similar test it is a gene expression profile in the cardiology transplant space. It utilizes 20 genes 11, which are specific for the test nine which are housekeeping and it does report a rejection risk. Next slide please. If we wanted to compare the test a little closer, you can see that there are a couple of differences. Initially, I'm from a sample type perspective, the heart transplant test 81595 does utilize whole blood that has been undergone a purification step to look at only PBMCs and then extracts RNA from those cells. In contrast, 815 6x or our new kidney CPT code does extract RNA from whole blood that has been collected in an RNA specific PAXgene to the other main difference is the heart transplant looks only at 20 genes while we were looking at 139 genes, both of them then go through a bio informatics algorithm with similar types of reporting regarding the status of rejection, and of the allograft. And that's all I have, are there any questions?

AGENDA 26

TRANSPLANT GENOMICS

Thank you. My name is Michelle Aldrich, and I am the clinical laboratory director for [Eurofins] Transplant Genomics. I'm here today to talk about the newly approved Category One CPT code 8156X for TruGraf Kidney.

• ·        Transplantation medicine (allograft rejection, kidney), mRNA, gene expression profiling by quantitative polymerase chain reaction (qPCR) of 139 genes, utilizing whole blood, algorithm reported as a binary categorization as transplant excellence, which indicates immune quiescence, or not transplant excellence, indicating subclinical rejection

 

Next slide, please.

This test is a gene expression profile used after kidney transplantation to detect subclinical rejection, with the goal of improving long-term outcomes and reducing the need to either return to dialysis or undergo a second transplant. The methodology is listed here. An alternative benefit of this test is that it will avoid the need for invasive and costly surveillance biopsies.

Next slide.

This slide lists the resources necessary to perform the test from a reagent, consumable, equipment, and labor standpoint. As illustrated, these resources are substantial. Additionally, there was significant R&D involved in the development and many clinical studies performed to demonstrate the clinical validity and utility of this assay. It is currently approved by MoDEX under General LCD.

Next slide, please.

Our crosswalk recommendation is to crosswalk to CPT code 81595, which is a similar test. It is a gene expression profile in the cardiology transplant space, utilizing 20 genes—11 specific for the test and 9 housekeeping genes—and it reports a rejection risk.

81595, $3240 (Allomap, CareDx)  Cardiology (heart transplant), mrna, gene expression profiling by real-time quantitative pcr of 20 genes (11 content and 9 housekeeping), utilizing subfraction of peripheral blood, algorithm reported as a rejection risk score

Next slide, please.

If we compare the tests more closely, there are a few differences. From a sample type perspective, the heart transplant test 81595 utilizes whole blood that has undergone a purification step to isolate PBMCs and then extracts RNA from those cells. In contrast, 8156X, our new kidney CPT code, extracts RNA from whole blood collected in an RNA-specific PAXgene tube. Another key difference is that the heart transplant test looks at 20 genes, while our test looks at 139 genes. Both tests then go through a bioinformatics algorithm with similar types of reporting regarding the status of rejection and the allograft.

That's all I have. Are there any questions?

AI Corner: SWIM Plots?

MolDx often asks clients in the minimal residual disease space for data as SWIM or SWIMMER plots.  I assumed this was because each patient's data "swims" across the page with timepoints for data points.

I asked Chat GPT about SWIM plots and it gave detailed instructions.   However, it also opened by given SWIM as an ACRONYM.   (See below).

I hadn't seen this before, and in fact, it didn't seem to be on Google.  I asked a separate Chat GPT session whether SWIM was the indicated statistical acronym, and it said NO, that wasn't a generally known acronym.    Ha!

But it's a nice one anyway!

##

I work with medical statistics and a technology review group asked for more of our data (summarized in a publication) in supplemental per patient "SWIM PLOTS". This is data such as tests for drug response in 50 patients.

SWIM plots (Summarized With Individual Measurements) are an effective way to present detailed per-patient data, especially in clinical studies involving drug response. These plots can show the timeline of various events or measurements for each patient, providing a clear visual representation of the data.

Here's a step-by-step guide on how you can create SWIM plots for your 50 patients' drug response data:

1. Data Collection:

   • Ensure you have the following data for each patient:
     • Patient ID
     • Dates of drug administration or tests
     • Test results or drug response values
     • Other relevant events (e.g., side effects, dose adjustments)

2. Data Organization:

   • Organize your data in a structured format, such as a spreadsheet. Each row represents a test or event for a patient.
   • Example format:

     Patient ID	Date	Event	Value
     001	2023-01-01	Drug Start	-
     001	2023-01-15	Test Response	0.5
     002	2023-01-01	Drug Start	-
     002	2023-01-20	Test Response	0.8

3. Plotting:

   • Use a plotting software or library that supports timeline visualizations, such as R (ggplot2), Python (matplotlib), or specialized software like GraphPad Prism.
   • Create a timeline plot where the x-axis represents time and the y-axis represents individual patients.
   • Each patient will have a separate row, and events or measurements will be marked along the timeline.

4. Example in Python (using matplotlib):

   python
   import matplotlib.pyplot as plt
   import pandas as pd
   
   # Sample data
   data = {
       'Patient ID': ['001', '001', '002', '002'],
       'Date': ['2023-01-01', '2023-01-15', '2023-01-01', '2023-01-20'],
       'Event': ['Drug Start', 'Test Response', 'Drug Start', 'Test Response'],
       'Value': [None, 0.5, None, 0.8]
   }
   
   df = pd.DataFrame(data)
   df['Date'] = pd.to_datetime(df['Date'])
   
   # Plot
   fig, ax = plt.subplots(figsize=(10, 8))
   
   patients = df['Patient ID'].unique()
   for i, patient in enumerate(patients):
       patient_data = df[df['Patient ID'] == patient]
       for _, row in patient_data.iterrows():
           if row['Event'] == 'Drug Start':
               ax.plot(row['Date'], i, 'go', label='Drug Start' if i == 0 else "")
           elif row['Event'] == 'Test Response':
               ax.plot(row['Date'], i, 'ro', label='Test Response' if i == 0 else "")
               ax.text(row['Date'], i, f'{row["Value"]}', fontsize=9, ha='right')
   
   ax.set_yticks(range(len(patients)))
   ax.set_yticklabels(patients)
   ax.set_xlabel('Date')
   ax.set_title('SWIM Plot')
   ax.legend()
   plt.show()
   

5. Interpretation:

   • Ensure each plot clearly shows the timeline for each patient.
   • Use different colors or markers to distinguish between different types of events (e.g., drug administration vs. test response).
   • Include legends and labels for clarity.

6. Supplemental Data:

   • Provide the SWIM plots as supplemental figures in your publication.
   • Include detailed captions explaining the plots and any relevant findings.

If you need more advanced customizations or have specific requirements for your plots, let me know, and I can provide further guidance or more detailed code examples.

AI Corner: Comparing First British Republic (1649-60) vs First Spanish Republic (1868-74)

 In the 1600s, what’s the name for the period in England after the death of King Charles?

The period in England after the death of King Charles I in 1649 is known as the Interregnum. This period lasted until 1660, during which England was a republic known as the Commonwealth of England. It was followed by the Restoration, which saw the return of the monarchy with King Charles II.

Was this something similar in Spain? /// In 1868, Spanish reformers toppled the monarchy of Queen Isabella II and established a new, if short-lived, republican regime…

Yes, a similar period occurred in Spain. In 1868, Spanish reformers indeed toppled the monarchy of Queen Isabella II, leading to the establishment of a short-lived republican regime. This period is known as the Sexenio Democrático (Democratic Sexennium), which lasted from 1868 to 1874. During this time, Spain experienced various forms of government, including a provisional government, a constitutional monarchy under King Amadeo I, and finally the First Spanish Republic, before the Bourbon monarchy was restored in 1874 with the reign of Alfonso XII.

Where did Isabella go?

After being deposed in 1868, Queen Isabella II went into exile in France. She initially settled in Paris, where she lived for several years. Despite her exile, she continued to be involved in Spanish politics and eventually abdicated the throne in favor of her son, Alfonso XII, in 1870. Alfonso XII later became king following the restoration of the Bourbon monarchy in 1874.

How does Amadeo fit?

Amadeo I, also known as Amadeo of Savoy, was chosen as the king of Spain following the deposition of Queen Isabella II and during the period known as the Sexenio Democrático. After Queen Isabella II was deposed and went into exile, Spain was in search of a new monarch to stabilize the country.

In 1870, the Spanish Cortes (parliament) elected Amadeo I as king. He was the second son of King Victor Emmanuel II of Italy and was seen as a neutral and modernizing figure. Amadeo I accepted the offer and began his reign on January 2, 1871. However, his reign was fraught with political instability, opposition from various factions, and widespread unrest.

Facing insurmountable challenges and lack of support, Amadeo I abdicated the throne on February 11, 1873. His abdication led to the establishment of the First Spanish Republic. The Republic itself was short-lived, and the monarchy was eventually restored in 1874 with the ascension of Alfonso XII, the son of Queen Isabella II.

Why was the 1873 republican so short? How did a (figurehead?) king help?

The First Spanish Republic, established in 1873 after the abdication of King Amadeo I, was short-lived due to several factors:

1. Political Fragmentation: The Republic faced deep political divisions between various factions, including federalists, centralists, radicals, and moderates. These groups had conflicting visions for the future of Spain, leading to frequent changes in government and policies.

2. Lack of Support: The Republic lacked broad support from key sectors of society, including the military, the church, and the aristocracy, who were traditionally aligned with the monarchy. This lack of support undermined its stability and effectiveness.

3. Economic Problems: Spain was experiencing significant economic difficulties, including widespread poverty and unemployment. The Republic struggled to address these issues, further eroding public confidence in the government.

4. Regional Separatism: There were strong separatist movements in regions like Catalonia and the Basque Country, which sought greater autonomy or independence. The central government's attempts to suppress these movements led to increased tensions and instability.

5. Carlist Wars: The Republic had to contend with the ongoing Carlist Wars, a series of civil wars involving supporters of the traditionalist Carlist claimants to the throne. The conflict drained resources and further destabilized the country.

6. Military Intervention: The military played a significant role in the politics of the period, often intervening to support or depose governments. In January 1874, General Pavia staged a coup and dissolved the Republican Cortes, leading to a period of military rule.

The return of a monarch, specifically Alfonso XII in 1874, helped stabilize the situation for several reasons:

1. Symbol of Unity: The monarchy served as a unifying symbol for many Spaniards, transcending the deep political and regional divisions that plagued the Republic.

2. Restoration of Order: The return of the monarchy was seen as a way to restore order and stability. Alfonso XII's reign began with efforts to reconcile different political factions and implement moderate reforms.

3. Military Support: The restoration of the monarchy had the backing of the military, which helped to quell uprisings and maintain order.

4. Political Moderation: Alfonso XII and his advisors pursued a more moderate and pragmatic approach to governance, avoiding the extremes that had characterized the Republic. This included integrating various political groups into the government and addressing some of the economic and social issues.

5. Historical Continuity: The monarchy represented a return to historical continuity, reassuring those who were wary of the radical changes and instability of the Republican period.

Overall, the return of the monarchy under Alfonso XII provided a sense of continuity, stability, and moderate governance that helped Spain recover from the turmoil of the previous years.

AI Corner: Chat GPT Compares Updates to FDA's Web Page about Payor Collaborations

AI Corner: Chat GPT Compares Two Very Similar Alzheimer Drug Labels

In early July 2024, FDA approved the Lilly Alzheimer drug KISUNLA (donanemab).   Here's the press release and here's the online full label.

Here's the closely similar label for last year's LEQEMBI, from Easai.

I gave Chat GPT 4 both PDF labels, about 22pp long each, and asked first for a comparision and then "forced" it to list 15 differences.   I haven't manually checked the differences, but this shows Chat GPT can give you a headstart at comparing the two 22 page PDFs.

###

There are the two PDF FDA drug labels for two similar Alzheimer drugs, KISUNLA from LILLY (Newer) and LEQEMBI from EISAI (from last year).   Much of the text and warnings are the same.   Please compare the two labels carefully and highlight for me where they are different.
