UDLCO summary :
Project principal investigators PIs collecting data regularly for each of the current 10 projects need to qualitatively thematically analyze on a case by case basis each of the 50-60 odd cases collected over last two years since their projects began. The conversational transcripts below describe a UDLC driven thematic analysis using human users that is perhaps quite akin to how multiple nodes in an artificial neural network would optimise input data toward an acceptable learning output after few iterations through deeper layers of nodes. The human user driven nodes performed comparably well at present and learning points from the first two thematic analysis on two cases is summarized below after every UDLC activity centered around each patient.

Theme diagnostic uncertainty :
The 75M patient's sepsis apparently resolved after administration of antibiotics chosen for an uncertain (retrospectively)/certain (prospectively to some actors during March 2024)as part of their urological localization of the sepsis."
Again in days to weeks, he showed another localization in the lungs and antibiotics were again targeted to another uncertain (retrospectively) /certain (prospectively) organism isolated from the lungs which didn't appear to resolve and he died and it's currently uncertain from the overall timeline if he died due to the organisms or due to his associated organ failures (comorbidities in heart, brain, kidneys) that contributed to the clinical complexity.

[5/31, 8:36 AM] Rakesh Biswas: This is the first case being analyzed?
[5/31, 8:37 AM] Aneef Elective May 2024: Yes sir
[5/31, 8:40 AM] Aneef Elective May 2024: Oh! Thank you ma'am for pointing it our
[5/31, 8:41 AM] Rakesh Biswas: The date of discharge in your case report mentions 5/4 while the available fever chart shows 8/4 and that too very high grade spikes!
How do you explain that @Kims Med Pg 2021 Nishitha ?
[5/31, 8:44 AM] Kims Med Pg 2021 Nishitha: Maybe it was typed wrong by our interns who made that discharge summary sir
I will check and get back to u
[5/31, 8:50 AM] Kims Med Pg 2021 Nishitha: Found it out sir
His frst case sheet was discharged and second case sheet was opened
But we continued the fever chart
[5/31, 8:53 AM] Rakesh Biswas: Yes but when was he discharged and was he discharged with those high fever spikes? How can we say then in his discharge that he recovered?
[5/31, 9:00 AM] Kims Med Pg 2021 Nishitha: Frst case sheet was discharged due to arogya sree issues sir so it was kept as recovered
Second case sheet was opened on the same day but They went on LAMA on 9th sir so there is no fever chart after 8th and pt went home with high grade fever spikes sir
[5/31, 9:06 AM] Rakesh Biswas: And what happened to the patient after that?
[5/31, 9:09 AM] Rakesh Biswas: It's written :
"ET TUBE CULTURE WAS SENT
ENTEROBACTER SPECIES WAS DETECTED"
Which date?
What drug sensitivity tests were run and what was it susceptible to?
Was it pathogenic for the patient? If so did he have a ventilator associated pneumonia VAP? Please share his chest X-ray asap
[5/31, 9:45 AM] Rakesh Biswas: The PI's not actively analyzing each of their 50 project patient participants by the steps detailed earlier will get an opportunity of 6 more months to do it
[5/31, 9:55 AM] Kims Med Pg 2021 Nishitha: He had low grade fever spikes at home for 2 days sir and fever subsided but patient suddenly died on 28/04/2024
[5/31, 10:01 AM] Aneef Elective May 2024: Wow! Thank you ma'am
[5/31, 10:01 AM] Aneef Elective May 2024: Is it acinetobacter ?
[5/31, 10:03 AM] Aneef Elective May 2024: I believe if it is an extended spectrum resistant acinetobacter, it was most probably VAP
[5/31, 10:06 AM] Kims Med Pg 2021 Nishitha: 06/04/2024
[5/31, 10:06 AM] Kims Med Pg 2021 Nishitha: His post intubation chest xray sir
[5/31, 10:19 AM] Rakesh Biswas: How many days post intubation?
Why can't this be cardiogenic pulmonary edema? @Aneef Elective May 2024
[5/31, 10:20 AM] Kims Med Pg 2021 Nishitha: Immediately after his intubation sir
[5/31, 10:21 AM] Rakesh Biswas: It can't be VAP then?
What's the definition of VAP @Aneef Elective May 2024 ?
[5/31, 10:22 AM] Rakesh Biswas: Can the organism decide the pathology? Prove it to me that this wasn't a commensal. Search for commensal Acinetobacter in the engine and share what you learn
[5/31, 10:35 AM] Aneef Elective May 2024: Sir my assumption was based on its wide resistance
[5/31, 10:41 AM] Rakesh Biswas: Why should someone who is tough automatically be designated criminal without a fair trial?
[5/31, 10:41 AM] Aneef Elective May 2024: https://www.ncbi.nlm.nih.gov/
All we need to know about acinetobacter sir. I am currently trying to find relevant information from this very long study π
[5/31, 10:43 AM] Aneef Elective May 2024: Sir please correct me if I am wrong. Because the blood is sterile, it shows that the infection was local uncomplicated UTI.
In addition, the patients overall picture and mortality too derives its root from a primary respiratory infection
[5/31, 10:44 AM] Rakesh Biswas: So as per @Kims Med Pg 2021 Nishitha's data on the chest X-ray shared above, the shadows were already there on day 1 of intubation and hence it doesn't satisfy the VAP definition?
[5/31, 10:48 AM] Aneef Elective May 2024: "In general, Acinetobacter spp. are found in wet environments, including moist soil/mud, wetlands, ponds, water treatment plants, fish farms, wastewater, and even seawater (3). These environmental strains often harbor antibiotic resistance mechanisms, including carbapenemases and extended-spectrum Ξ²-lactamases (ESBLs) (3), and may thus serve as important environmental reservoirs for resistance elements that transform into clinically relevant strains."
Al Atrouni A, Joly-Guillou ML, Hamze M, Kempf M. 2016. Reservoirs of non-baumannii Acinetobacter species. Front Microbiol 7:49. doi: 10.3389/fmicb.2016.00049.
[5/31, 10:51 AM] Aneef Elective May 2024: Sir interestingly, the environmental form itself is Multi drug resistant π
[5/31, 10:55 AM] Rakesh Biswas: What primary respiratory infection?
What is the incidence of urine cultures positive uti also testing positive in blood culture?
[5/31, 10:56 AM] Rakesh Biswas: Why shouldn't it be?
Why should someone who is tough automatically be designated criminal without a fair trial?
[5/31, 11:17 AM] Aneef Elective May 2024: Background
To effectively treat sepsis and urinary tract infection (UTI), blood and urine cultures should be used appropriately and relative to incidences of bacteremia and bacteriuria. This study aimed to investigate the use of blood and urine cultures and incidences of bacteremia and bacteriuria in a hospital in Thailand.
Methods
Medical records of patients admitted from 2016 to 2018 were randomly selected and data in the records were anonymously extracted for investigation.
Results
From 12 000 records, data on blood and urine cultures were extracted from 9% and 4% of them, respectively. *The negative rate of blood culture was 87.48%*. Bacteremia was detected in 10.22%. The positive rate of urine culture was 27.38%
Conclusions
A high negative rate of blood culture may result not only from its low sensitivity but also from liberal test use to identify sepsis in some conditions. Improper urine collection is the main problem with use of urine culture.

Hope this clarifies
[5/31, 11:27 AM] Rakesh Biswas: Share the "fever project" learning points from this patient as per your initial objectives and let's quickly close this case and move to the next?
[5/31, 12:00 PM] Kims Med Pg 2021 Nishitha: Sir in this case we have diagnostic uncertainity and therapeutic uncertainity of his fever
Is it because of the E. Coli from urine or acenetobacter from ET and what should be treated
Leaning point here is at frst the antibiotic we started was sensitive to e. Coli and his fever spikes subsided but after intubation was done the organism isolated was resistant to the same antibiotic and his fever spikes were persistent and were high grade
[5/31, 12:29 PM] Kims Med Pg 2021 Nishitha: So we cannot treat every organism with the same antibiotic or we shouldnt give patient antibiotics which are of no use or for which they are resistant
[5/31, 12:47 PM] Kims Med Pg 2021 Nishitha: Even after we got culture reports and changing the antibiotic ultimately patient outcome (death) didn't change sir
This is the therapeutic uncertainty in this case
[5/31, 12:51 PM] Kims Med Pg 2021 Nishitha: Diagnostic uncertainity is whether the patient had his fever spikes due to isolated E. Coli or acenetobacter or any other cause
[5/31, 12:55 PM] Rakesh Biswas: I can see that we are now somewhat on the right track.
Can the above learning points be expressed in a better written manner @Chandana Kims Med PG @Aneef Elective May 2024 ?
[5/31, 1:42 PM] Chandana Kims Med PG: I have a doubt sir.
RESOLVING DIAGNOSTIC AND THERAPEUTIC UNCERTAINTIES AND IMPROVING OUTCOMES IN PATIENTS WITH UNDIFFERENTIATED FEVER
What do we mean by undifferentiated fever?
Going by literature , undifferentiated fever is when there is no localizing signs of infection.(ex-dengue,other viral fevers, malaria,typhoid,leptospira etc)
Why are we including urosepsis and aspiration pneumonia case?
@Kims Med Pg 2021 Nishitha
[5/31, 1:50 PM] Kims Med Pg 2021 Nishitha: His urosepsis resolved with our treatment mam
I included this case because he has no symptoms of aspiration pneumonia but has fever spikes
After chest xray was taken and et culture was positive we got to know the cause
[5/31, 1:53 PM] Chandana Kims Med PG: Yes exactly..when we evaluate and find out a cause or localise a fever it doesnt become undifferentiated fever.
[5/31, 2:00 PM] Rakesh Biswas: Good point!
[5/31, 1:55 PM] Chandana Kims Med PG: The term acute undifferentiated febrile illness (AUFI) connotes fever of <14 days duration without any evidence of organ or system specific aetiology
[5/31, 1:58 PM] Aneef Elective May 2024: Does Acute decompensated heart failure have fever as a symptom?
[5/31, 1:59 PM] Aneef Elective May 2024: To bring it to context, This patient has been on diuretics lasix 40 mg and has history of HTN and DM and CVA
[5/31, 2:01 PM] Rakesh Biswas: Comorbidities adding to clinical complexity
[5/31, 2:02 PM] Chandana Kims Med PG: Acute decompensated heart failure (ADHF) typically does not present with fever as a primary symptom. The common symptoms of ADHF include:Shortness of breath(dyspnea), particularly when lying down (orthopnea) or during physical activity, Swelling(edema),palpitations , cough, and reduced exercise tolerance.
However, fever in a patient with ADHF might indicate an underlying infection or other complicating condition. For example: co existing UTI, pneumonia or myocarditis or endocarditis
[5/31, 2:03 PM] Aneef Elective May 2024: Thank you ma'am for this elaborate explanation
[5/31, 2:09 PM] Rakesh Biswas: To rephrase it again : I guess you meant,
"His sepsis apparently resolved after administration of antibiotics chosen for an uncertain/certain urological localization."
However he showed another localization in the lungs and antibiotics were again targeted to another uncertain/certain organism isolated from the lungs which didn't appear to resolve and he died and it's uncertain if he died due to the organisms or due to his associated organ failures that contributed to the clinical complexity.
@Chandana Kims Med PG Does this now sound like a good contender to your second paper as the first here π
"Understanding clinical complexity in organisms and organ systems
[5/31, 2:12 PM] Chandana Kims Med PG: Yes sir
[5/31, 2:14 PM] Rakesh Biswas: Let's quickly dig out the organismal and organ system complexities in the other ProJRs asap
[5/31, 2:14 PM] Aneef Elective May 2024: Yes sir
Second case :
UDLC summary :
A 45F woman with lowbackache and CKD since many years and recently sepsis brewing for 1 month, presented with undifferentiated fever and encephalopathy that was attributed to sepsis. In our recently published past analysis of CKD sepsis cases, we showed that patients with chronic kidney disease sepsis and lowbackache had vertebral-spinal pathologies due to poor infection control measures during haemodialysis. All these patients were young with a long history of secondary hypertension. https://pubmed.
In this patient,given the clinical presentation overlap, both septic and uremic encephalopathy can present with altered mental status, making differential diagnosis challenging.
Recognition and treatment of potential sepsis are essential, even in the absence of clear localization of infection.
Negative cultures do not exclude sepsis, clinical judgment and continued observation are vital.
The lack of improvement in mental status and persistent fever despite adequate hemodialysis suggests a diagnosis other than uremic encephalopathy, supporting septic encephalopathy.
Conversational transcripts :
[5/31, 3:14 PM] Kims Med Pg 2021 Nishitha: https://anahitabehara.
[5/31, 6:59 PM] Rakesh Biswas: Is date of admission really 24/4??
Did she spend 1 month here??
[5/31, 7:00 PM] Rakesh Biswas: Is this the second thesis patient for discussion among your 50 patients?
[5/31, 7:45 PM] Chandana KIMS 2020 SR: I think it is the admission date on case sheet (opened for 10 day care dailysis) but she became bad someday in between and came to icu . When was she admitted to icu? @Kims Med Pg 2021 Nishitha
[5/31, 8:00 PM] Kims Med Pg 2021 Nishitha: Sir she was admitted on 24/4 for maintenence hemodialysis and was coming only for dialysis once a week
Then she had high grade fever we advuced admission but they didnt want to stay back after dialysis and took her back home
Then when she came for hemodialysis she suddenly went into altered sensorium and was admitted to icu on 11/05 night sir
[5/31, 8:50 PM] Kims Med Pg 2021 Nishitha:
Fever could not be localized in this case, and cultures came back negative. Despite daily hemodialysis for 7 days, the patient did not improve and continued to have fever spikes and altered sensorium, making septic encephalopathy highly likely rather than uremic encephalopathy and also one day in between when her counts came down her gcs improved and she was able to talK few words and was oriented but again the next day counts again increased and her gcs and sensorium came down
Later, the patient succumbed to death after leaving the hospital against medical advice.
Learning points-
Clinical Presentation Overlap,both septic and uremic encephalopathy can present with altered mental status, making differential diagnosis challenging.
Recognising and treatment of potential sepsis are essential, even in the absence of clear localization of infection.
Negative cultures do not exclude sepsis, clinical judgment and continued observation are vital.
The lack of improvement in mental status and persistent fever despite adequate hemodialysis suggests a diagnosis other than uremic encephalopathy, supporting septic encephalopathy.
Bedsores can introduce new infections
Uncertainty-
Diagnostic-Negative blood cultures
Non localised (undifferentiated) fever
Therapeutic-
Persistent fever and altered sensorium despite daily hemodialysis and antibiotics for 7 days strongly suggest septic encephalopathy, as uremic symptoms should improve with dialysis. Possibility of drug resistant organism is there.But it also maybe due to middle molecules even though her urea was normal
Bore sore development later made the diagnosis more uncertain as it can also contribute to fever(although it developed later)
[5/31, 8:59 PM] Rakesh Biswas: Wow! ππ
That's very rapid progress since the first case this morning!
Can you share some relevant review of literature to septic encephalopathy and similar case reports of the same in the background of dialysis patients.
Again @Chandana KIMS 2020 SR , Karnati Vaishnavi and Aditya's last paper was largely around the complexity of managing sepsis in our dialysis patients
