Brain imaging techniques can help scientists understand what is going on inside the heads of patient populations.

In their recent study published in PLOS ONE, Dr. John Aucott and Cherie Marvel found that unexpected white matter activity in the brain, a symptom normally considered pathological, was found to be correlated with better outcomes in patients with post-treatment Lyme disease (PTLD).

PTLD occurs in patients who have received treatments for Lyme disease but have yet to fully recover. Persistent complaints about cognitive difficulty are one of the symptoms.

Aucott is an associate professor in the Division of Rheumatology at the School of Medicine. He is also the director of the Lyme Disease Clinical Research Center and a clinical-translational researcher in Lyme disease with a focus on PTLD.

He stressed that PTLD affects 10% to 20% of patients who were previously diagnosed with and treated for Lyme disease in an interview with The News-Letter.

“Post-treatment Lyme disease is not a trivial problem. It is a problem that should be noticed,” he said.

Marvel is a cognitive neuroscientist and an associate professor of Neurology at the School of Medicine. She has been using brain imaging methods to look at different cognitive and motor functions, primarily in clinical populations.

In an interview with The News-Letter, Marvel noted that the complaints of PTLD patients did not align well with the standard cognitive or neuro-psychological testing.

“So we thought we should look inside the brain. The way we can do that non-invasively is through functional MRI,”she said.

Participants were asked to perform working memory tasks while their brain activity was recorded by functional magnetic resonance imaging (fMRI). fMRI measures brain activity by detecting increased oxygen level in areas of activation.

Aucott highlighted that the decision to use an fMRI test for the study was intentional.

“The mystery behind post-treatment Lyme disease is whether there is something biological going on. Tests that are normally available to clinicians, such as regular MRI or CT, scans can’t identify these,“ he said. “So we hypothesized that stress tests under fMRI would be more sensitive to any biological changes.”

All participants performed two tasks. The easier task, which was the control condition, required participants to remember two letters for a short duration. After, the screen would show a new letter, and the participant would need to evaluate whether it was one of the two letters previously shown.

The harder task, which was the experimental condition, required participants to count two alphabetical letters forward of the same two letters and remember the new letters. Then, they were asked if a newly-appeared letter was one of the two new letters.   (See link for article)

**Comment**

It is disingenuous to use the PTLD moniker for many reasons:

  1. It denies persistent infection
  2. It only includes the smaller subset of patients that have bee diagnosed and treated early and omits the larger subset of patients that are diagnosed and treated late
  3. Those with persistent symptoms may develop secondary psychosomatic & psychiatric disorders.  By using the PTLD moniker, treatment will only address the secondary conditions, but continue to deny life-saving antimicrobials
This is crucial because ignoring these facts will only propagate the continuing under-treatment (or denying treatment altogether) of severely ill patients

SUMMARY:

  • The researchers found expected brain activity in the gray matter but also in the white matter, which wasn’t expected.
  • White matter cells communicate signals between gray matter.
  • The finding caused the researchers to look more closely at the phenomenon.
  • Axial diffusivity (water leaking along the axon) is how the neurons relay electrical signals to each other and increased axial diffusivity was correlated with better outcomes and few symptoms.
  • Aucott states this response appears to be the body’s compensatory response to slower cognitive functions and is similar to a positive response to injury.
  • The researchers want to follow patients longitudinally as well as look for inflammatory markers through cerebral fluid samples.

Abstract

Blacklegged ticks, Ixodes scapularis, can transmit single or multiple infections during a tick bite. These tick-borne, zoonotic infections can become chronic and cause insidious diseases in patients.

In the present tick-pathogen study, 138 (48.9%) of 282 ticks collected from 17 sites in 6 geographic area in eastern Canada harbored various combinations of Borrelia burgdorferi sensu lato (Lyme disease), Anaplasma phagocytophilum (human anaplasmosis), and Babesia spp. (human babesiosis). Overall, 167 microbial infections were detected and, of these, 25 ticks had co-infections and two ticks had polymicrobial infections.

  • the prevalence of Babesia spp. was 15.2%
  • the ratio of Babesia odocoilei to Babesia microti was 41 to 1 with this sole B. microti being detected in Nova Scotia
  • we provide the first documentation of B. odocoilei in the Maritimes
  • Eastern Ontario had an infection prevalence for B. odocoilei of 25%―the highest among the areas surveyed in this study
  • the predominant Babesia sp. was B. odocoilei

Based on our findings, health-care practitioners need to recognize that I. scapularis ticks removed from patients may be carrying multiple tick-borne pathogens.  (See link for article)

DNA amplicons from these two patients are almost identical matches with the type strains of B. odocoilei in GenBank. In addition, the same two human subjects had the hallmark symptoms of human babesiosis, including night sweats, chills, fevers, and profound fatigue. Based on symptoms and molecular identification, we provide substantive evidence that B. odocoilei is pathogenic to humans. Dataset reveals that B. odocoilei serologically cross-reacts with Babesia duncani.

RMSF Masquerading as Gastroenteritis

Rickettsia – Rocky Mountain Spotted Fever Masquerading as Gastroenteritis

By R.E.D. Laboratories

The recent article by Braun et al. explains the importance of test for Ricketissa tick-borne infection. This infection can hide numerous symptoms like fever, rash, gastrointestinal symptoms such as anorexia, nausea, vomiting, and abdominal pain.

The article: Rocky Mountain Spotted Fever Masquerading as Gastroenteritis: A Common but Overlooked Clinical Presentation, shows a case of a 20-year-old male presented to the emergency department with many alarming symptoms.

It is important to test for Rickettsia in order to help identifying infection rapidly as well as avoid expensive workups and invasive procedures which may delay the needed treatment.

To ensure the detection of Rickettsia infections, R.E.D. Laboratories propose the new Phage Rickettsia test which can uncover a broad range of Rickettsias: Rickettsia japonica (multiple strains); Rickettsia heilongjiangensis (multiple strains); Rickettsia parkeri (multiple strains); Rickettsia raoultii (multiple strains); Rickettsia rickettsia (multiple strains); Rickettsia slovaca (multiple strains); Rickettsia montanensis; Rickettsia peacocki; Rickettsia africae; Rickettsia conorii.

Background: Lyme disease (LD) is a complex tick-borne pathology caused by Borrelia burgdorferi sensu lato bacteria. Currently, there are limited data regarding the health outcomes of people infected during pregnancy, the potential for perinatal transmission to their fetus, and the long-term effects on these children. Therefore, the primary objective of this survey study was to investigate the impact of LD in pregnancy on both the parent and their offspring.

Methods: A seven-section survey was developed and administered in REDCap. Although recruitment was primarily through LD-focused organizations, participation was open to anyone over the age of 18 who had been pregnant. Participant health/symptoms were compared across those with “Diagnosed LD,” “Suspected LD,” or “No LD” at any time in their lives. The timing of LD events in the participants’ histories (tick bite, diagnosis, treatment start, etc.) were then utilized to classify the participants’ pregnancies into one of five groups: “Probable Treated LD,” “Probable Untreated LD,” “Possible Untreated LD,” “No Evidence of LD,” and “Unclear.”

Results: A total of 691 eligible people participated in the survey, of whom 65% had Diagnosed LD, 6% had Suspected LD, and 29% had No LD ever. Both the Diagnosed LD and Suspected LD groups indicated a high symptom burden (p < 0.01). Unfortunately, direct testing of fetal/newborn tissues for Borrelia burgdorferi only occurred following 3% of pregnancies at risk of transmission; positive/equivocal results were obtained in 14% of these cases. Pregnancies with No Evidence of LD experienced the fewest complications (p < 0.01) and were most likely to result in a live birth (p = 0.01) and limited short- and long-term offspring pathologies (p < 0.01). Within the LD-affected pregnancy groups, obtaining treatment did not decrease complications for the parent themselves but did ameliorate neonatal health status, with reduced rates of rashes, hypotonia, and respiratory distress (all p < 0.01). The impact of parent LD treatment on longer-term child outcomes was less clear.

Conclusion: Overall, this pioneering survey represents significant progress toward understanding the effects of LD on pregnancy and child health. A large prospective study of pregnant people with LD, combining consistent diagnostic testing, exhaustive assessment of fetal/newborn samples, and long-term offspring follow-up, is warranted.

**Comment**

And that long-term offspring follow-up will never happen unless independent researchers take it upon themselves.  Our government just wants this to all go away – except for acute cases for which a lucrative “vaccine,” can be created, which is always viewed as a magic-bullet and will be a cash-cow with big profit margins.

The little we know about congenital Lyme has come primarily from Dr. Jones, RIP and a nurse who personally gathered all the research done on congenital Lyme disease out of the goodness of her heart and out of necessity for her own family.  This is typically how we finally get some answers, and frankly the best way to get real answers that are helpful.

Aren’t you tired of funding research with our tax dollars that doesn’t help patients?

Science, Public Health Policy & the Law Has Accepted Dr. Sin Hang Lee’s Study of the Flaws of Non-Quantitative RT-PCT For SARS-CoV-2 Detection – Part 1

**UPDATE**

Go here for another excellent read on how for a 5% prevalence rate for COVID infections in a population, the 42% false positive discovery rate means that for every 50 true positives, there will be 36 false positives.  Ponder that for a moment.

COVID cases will be overstated by a factor of 72%

Due to unreliable of PCR tests:

There are no credible COVID-19 ‘vaccine’ trial data.

Science, Public Health Policy & the Law has Accepted Dr. Sin Hang Lee’s Study of the Flaws of Non-Quantitative RT-PCR for SARS-CoV-2 Detection – Part 1

Sanger Sequencing Provides Definitive Evidence that RT-PCR Use with No Internal Control Applied to the Problem of Diagnosis of COVID-19 is Fatally Flawed

When the German team (Cormen et al. (aka “Drosten Report”)) published primers capable of detecting synthetic oligonucleotide that matched parts of the SARS-CoV-2 genome sequence published from the first clinical sample from the first patient diagnosis of pneumonia associated with a novel coronavirus, there was hope that the virus might be controlled at least until healthcare facilities could be made ready using the training and preparations they conducted during the Ebola care of 2014.

The use of PCR to detect specific sequences is trivially non-controversial, if it is done in an expert manner. First, the primers are chosen computationally to match only the target species (or quasi-species, in the case of viruses). Second, multiple targets can be selected that help nail down the results in case one of the single. Finally, if the primers are nested or hemi-nested – that is if the targets sequences overlap, a local sequence can reliably be determined on a percentage of the samples as a direct gold-standard check to estimate both the true positive rate (the probability of detecting a virus that is truly present) and the false positive rate (the probability of detecting the target when it is truly not present).

I expected when CDC’s PCR test failed that there would likely be a variety of approaches that would be developed by commercial nucleic acid technology companies. I started advocating for private mass testing, with an emphasis on “private”, expecting that accurate testing would emerge.

I was astonished when I saw that the FDA had only requested that commercial suppliers provide data on the true positive rate, but no data on the false positive rate. Worse, I was astonished to learn, upon reading the documents being submitted to the FDA, that the test kit manufacturers were not including positive control sample material to allow the determination of cycle threshold (Ct) by which one makes the call for a given patient that the virus was present or absent. Cycle thresholds are the number of rounds of amplification necessary to reach a specific point in the exponential growth of the number of copies of target sequences. This must be done for each patient separately – even if the test is the same kit done in the same lab, on the same day, by the same technician – because the amount of starting material in each swab varies.

This was the first time I had ever seen any RT-PCR-based test NOT use a positive control sample. The lack of a positive control sample means that the assay was qualitative, not the robust and rigorous qRT-PCR (“q” stands for “quantitative”. For example, even the RT-PCR test for the Monkeypox virus uses a positive control sample.

Instead of using empirically derived Ct values per patient, generic Ct values were used. These were part of the kits, but they were not published. This was unusual. I asked medical freedom activists to request from their local health department what Ct values were being used to determine a diagnosis for a patient. Multiple people did, and the reply was the same: that information is proprietary. This was ridiculous; the exact Ct being used is not a top-secret part of a test, but is, instead, an essential aspect of checking the reliability of the results of an RT-PCR test.

Go to top link for a video on RT-PCR.

The absence of a positive control target sample was a big deal because, without any data on whether tests were hitting human sequences via off-target amplification, many people would be “diagnosed” with COVID-19 who were not infected. This would not only be disruptive – the resulting huge numbers of false positives could be used to justify police actions as was going on in China at the time.

Further, people who had other respiratory illnesses like influenza, respiratory syncytial virus, bacterial pneumonia, the common cold, or other coronaviruses might not be given appropriate medical care given the isolate-and-do-nothing approach to COVID-19. Many would die from severe pneumonia that could have been prevented via medical intervention, just as antibiotics for bacterial pneumonia.

Also, it was clear that many people who were sick but did not have COVID-19 would believe thereafter they were immune, and they might risk exposures that they otherwise might not risk.

In addition, those that did then become infected after their false positive COVID-19 test might then doubt their actual case of SARS-CoV-2 infection was worth testing for and they might fail to protect others who were at the highest risk of death from COVID-19 infection – the immunocompromised and the elderly.

So I wrote to the FDA with my concerns. Dr. Peter Marks wrote back with a terse “Thank you, we will take your concerns up with my team”.

At the same time, Dr. Sin Hang Lee independently saw the same issues and was motivated to develop a Sanger sequencing-based test. His approach circumvented the risk of false positives altogether by using primer pairs that targeted parts of the SARS-CoV-2 genome in an overlapping mapper. This way, he could tell if he truly had the sequence of interest in a sample, or if one of the primer pairs was failing due to a mutation in the primer site.

Dr. Lee is an extremely capable and experienced scientist and is an expert in molecular diagnosis and diagnostic pathology. The fact that he independently came to the same conclusion as I did on the risks of using RT-PCR the way CDC, ultimately, FDA allowed under emergency use authorization gave me hope.

July 2020 WWDNYK’s Unbreaking Science: CDC PCR Test Wrong 1/4 of the Time

See top link for a video from about the time I contacted FDA (Nov 2020).

After writing various blog articles and doing podcasts attempting to alert the public and health departments to these very serious issues, I was invited to testify in a case in Pennsylvania wherein a restauranteur was sued by the Commonwealth for not following the public health dictates regarding her customers.

Originally, the testimony was meant to be written. So I provided the judge with the scientific literature on measured false positive rates of the RT-PCR tests. There were about four studies that provided data that demonstrated that the false positive rates varied from 11% (Basile et al.) to as high as 38% (the Duke Marines study).

The State Epidemiology submitted her testimony at the same time, without seeing mine. (I did not see hers, either). When I was given a copy of her testimony, I could see she knew nothing about the state of the science on the use of RT-PCR as allowed by CDC and PCR. She reported to the judge in her written testimony that RT-PCR tests for COVID-19 had – get this – ZERO false positives.

That’s when the judge, for reasons I will never understand, refused both sets of written testimony, and instead decided that only verbal testimony was going to be allowed. Of course, the State’s lawyer used the only tool they had – ad hominem attack – to try to discredit me. But even that didn’t change the fact that RT-PCR tests were visiting abuse on the public via false positives as outlined above.

A group of people became increasingly aware of the issues, and together we created NAATEC, the Nucleic Acid Assay Technology Evaluation Consortium – to collect public funds and fund the comparison of RT-PCR testing to Sanger sequencing.

I am happy to report that we thereby funded research by independent research scientist Dr. Sin Hang Lee to conduct the evaluation that FDA should have required by PCR test kit manufacturers.

The study underwent a single-blind peer review with two independent reviewers not involved in the study. The peer reviewers were scientists and experts in the field. After two rounds of feedback from the reviewers, the manuscript was accepted for publication and is with the editorial production team.

Prior to publication, I am providing the title, author, and Abstract.

Evidence-Based Evaluation of PCR Diagnostics for SARS-CoV-2 and the Omicron Variants by Sanger Sequencing

Dr. Sin Hang Lee

Abstract: Both SARS-CoV-2 and SARS-CoV-1 initially appeared in China and spread to other parts of the world. SARS-CoV-2 has generated a COVID-19 pandemic causing more than 6 million human deaths worldwide while the SARS outbreak quickly ended in six months with a global total of 774 reported deaths. One of the factors contributing to this stunning difference in the outcome between these two outbreaks is the inaccuracy of the RT-PCR tests for SARS-CoV-2, which generated a large number of false-negative and false-positive test results that have misled patient management and public health policymakers. This article presented Sanger sequencing evidence to show that the RT-PCR diagnostic protocol established in 2003 for SARS-CoV-1 can in fact detect SARS-CoV-2 accurately due to the well-known ability of the PCR to amplify similar, homologous sequences. Using nested RT-PCR followed by Sanger sequencing to retest 50 patient samples collected in January 2022 and sold as RT-qPCR positive reference confirmed that 21 (42%) were false-positive. Routine sequencing of the RT-PCR amplicons of the receptor-binding domain (RBD) and N-terminal domain (NTD ) of the Spike protein (S) gene is a tool to avoid false positives and to study the effects of amino acid mutations and multi-allelic SNPs in the circulating variants for investigation of their impacts on vaccine efficacies, therapeutics. and diagnostics.

The study was partially funded by IPAK via the NAATEC. To support research like this, visit http://ipaknowledge.org/

Watch for Part 2 at the end of the month – the details of the study will be explained.
