Creutzfeldt-Jakob disease (CJD) is a rapidly progressive fatal prion disease. Although most cases are sporadic or inherited, prions may be transmitted via contaminated tissues or durable medical equipment.1,2 The risk of iatrogenic transmission is highest following procedures involving the central nervous system, where prion burden is highest.2,3 However, experimental models suggest that transmission may occur following contact with other tissues (eg, nasal mucosa, lung, lymph nodes, and spleen).4 If these models are accurate, surgical procedures involving these tissues may pose a risk to future patients. To evaluate the potential scope of this problem, we determined the frequency of invasive procedures performed in patients with CJD at multiple tertiary care centers.
Methods
Protocols for this case-control study were approved by the Mayo Clinic institutional review board. A waiver of consent was granted for the use of retrospective, deidentified data. This study follows the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) reporting guideline. An automated search of Mayo Clinic records identified 252 of 1 843 675 patients with diagnostic evaluation including “CJD” or “prion disease” evaluated from January 2014 (the time at which specific biomarkers of prion disease were incorporated within clinical practice) to February 2021 at Mayo Clinic locations in Rochester, Minnesota; Jacksonville, Florida; and Phoenix, Arizona. Fourteen patients at Washington University (Saint Louis, Missouri) were enrolled from February 2016 to December 2019 within prospective studies of rapid progressive dementia. Available records were dual-reviewed (April 2021) to identify patients who met criteria for probable CJD (neuropsychiatric disorder with positive cerebrospinal fluid real-time quaking-induced recovery assays; or rapidly progressive dementia with 1 or more of the following signs and symptoms: myoclonus, visual or cerebellar signs, pyramidal or extrapyramidal signs, akinetic mutism, and consistent brain magnetic resonance imaging; 71 patients) or definite CJD (pathologically or genetically confirmed, 50 patients)5 and to capture surgical procedures. Procedures performed within 1 year of the onset of symptoms attributed to CJD were counted to include the presymptomatic period associated with latent prion accumulation. Procedures were stratified by risk of prion contamination of instruments.3,4 Statistical analysis was performed using SPSS statistical software version 28.0 (IBM), using Pearson χ2 tests for categorical variables and Mann-Whitney U tests for continuous variables to evaluate the association between patient-specific factors and procedures. Significance was set at P < .10 due to the exploratory nature of this analysis. Data were analyzed from March 2021 to June 2021.
Results
In total, 26 of 121 patients (21%) (63 female patients [52%]; median [range] age, 65.4 [21.9 to 81.5] years) with CJD underwent 55 procedures, including high-risk procedures in 2 patients with neuropathologically proven CJD (Table 1). Procedures were more frequent in patients with a history of arthritis (odds ratio [CI] 5.58 [1.16-26.7], P = .02) and possibly less frequent in patients with behavioral symptoms or signs at presentation (odds ratio [CI] 0.43 [0.16-1.17]. P = .093) (Table 2). Median times from symptom onset to brain magnetic resonance imaging and electroencephalogram were greater in patients who underwent procedures, suggesting that diagnostic delays were associated with procedures. Seventeen of 32 procedures (53%) were performed in the months prior to symptomatic onset (median [range,] −5.4 [−0.2 to −10.8] months). Appropriate procedural precautions were observed in 1 patient.
Discussion
Invasive procedures were frequently performed in patients with CJD included in this case-control study. Actual numbers of procedures may have been even greater, recognizing that procedures performed at outside hospitals may have been overlooked or excluded from records. Replication of study methods within additional hospitals—including community-based centers—is required to confirm these findings and establish the generalizability of results.
Features of sporadic CJD typically manifest in the sixth through eighth decades of life (median age, 68 years),5 a time when gait abnormalities, sensorimotor complaints and visual changes may be mistaken for common age-related surgically responsive conditions, leading to surgical procedures in this cohort and others.6 Thus, it is essential to accurately decipher the cause of symptoms and signs in clinical practice (eg, distinguishing between difficulty walking due to joint pain vs ataxia due to CJD). Preoperative risk assessment tools may identify patients at risk of CJD, for whom elective surgical procedures should be deferred and emergent procedures completed under precautions.2 However, prescreening cannot prevent invasive procedures in presymptomatic patients. National registries may address this problem. In the US, The National Prion Disease Pathology and Surveillance Center systematically collects data from patients with suspected CJD. Incorporating questions on recent invasive procedures would allow early notification of surgeons or facilities when a diagnosis of CJD is confirmed, permitting quarantine, decontamination, or decommissioning of affected instruments. This would also allow for prospective surveillance in larger numbers of patients, providing data needed to replicate our findings and quantify the scope of the potential problem posed by surgical procedures in patients with CJD.

Greetings Voice,
i send this 'CJD Foundation Questionnaire' and ask the group, what they suppose will be found out with this ???
with this questionnaire, in my opinion, they don't want to know what/where the routes and sources of CJDs in theUSA are coming from. NO WONDER they said i was interfering with there research, there research consist of _not_ finding out anything other than how it was diagnosed.
you folksjudge for yourself. maybe i'm just being an extremist as some say???
then again, maybe not...TSS

Dear xxxx:
Creutzfeldt-Jakob Disease Study Neuroepidemiology Section Department of Neurology, Rm 1580 School of Medicine Loma Linda, California 92350
July 9, 1991
The Department of Neurology of Loma Linda University is conducting a multi-state study of Creutzfeldt-Jakob disease to identify risk factors for this disease. This study is federally funded by a grant from the National Institute of Neuroiogic Disorders and Stroke (NINDS) of the National Institutes of Health (NIH).
We recently contacted the Texas Department of Health in Austin and according to their records xxxxx xxxxxx had Creutzfeldt-Jakob disease.
We would like for you to participate in this study of Creutzfeldt-Jakob disease. This research project may be of great benefit in preventing this disease.

Dear xxxx,
Thank you for participating in the Creutzfeldt-Jakob disease study. Your participation and interest in this important research project are greatly appreciated.
The research project on Creutzfeldt-Jakob disease is progressing very well. We have met and even exceeded our goal of interviewing 100 families who had a relative with Creutzfeldt-Jakob disease. In fact, we have interviewed 119 families who had a relative with Creutzfeldt-Jakob disease. Moreover, we have interviewed 105 control subjects (i.e., non-demented subjects) and are in the process of finding additional control subjects and interviewing them to compare the data with the individuals who had Creutzfeldt-Jakob disease. We expect to complete this research project in a couple of years and then we will analyze all of the information that we have collected. Once research results become available we will share the information with you and your family, if you so indicate on the enclosed form. Of course, no identifying information on any subject will be released.

HISTORY OF USA QUESTIONNAIRE ;
Monitoring the occurrence of emerging forms of Creutzfeldt-Jakob disease in the United States 2003 revisited 2009
Saturday, July, 18, 2009
Greetings,
I would like to submit a review of past CJD surveillance in the USA, and the urgent need to make all human TSE in the USA a reportable disease, in every state, of every age group, and to make this mandatory immediately without further delay. The ramifications of not doing so will only allow this agent to spread further in the medical, dental, surgical arena’s. North America seems to have the most species with documented Transmissible Spongiform Encephalopathy's, most all of which have been rendered and fed back to food producing animals and to humans for years. If you look at the statistics, sporadic CJD seems to be rising in the USA, and has been, with atypical cases of the sCJD. I find deeply disturbing in the year of 2009, that Human Transmissible Spongiform Encephalopathy of any strain and or phenotype, of all age groups, and I stress all age groups, because human TSE's do not know age, and they do not know borders. someone 56 years old, that has a human TSE, that has surgery, can pass this TSE agent on i.e. friendly fire, and or passing it forward, and there have been documented nvCJD in a 74 year old. Remembering also that only sporadic CJD has been documented to transmit via iatrogenic routes, until recently with the 4 cases of blood related transmission, of which the origin is thought to be nvCJD donors. However most Iatrogenic CJD cases are nothing more than sporadic CJD, until the source is proven, then it becomes Iatrogenic. An oxymoron of sorts, because all sporadic CJD is, are multiple forms, or strains, or phenotypes of Creutzfeldt Jakob Disease, that the route and source and species have not been confirmed and or documented. When will the myth of the UKBSEnvCJD only theory be put to bed for good. This theory in my opinion, and the following there from, as the GOLD STANDARD, has done nothing more than help spread this agent around the globe. Politics and money have caused the terrible consequences to date, and the fact that TSEs are a slow incubating death, but a death that is 100% certain for those that are exposed and live long enough to go clinical. once clinical, there is no recourse, to date. But, while sub-clinical, how many can one exposed human infect? Can humans exposed to CWD and scrapie strains pass it forward as some form of sporadic CJD in the surgical and medical arenas? why must we wait decades and decades to prove this point, only to expose millions needlessly, only for the sake of the industries involved? would it not have been prudent from the beginning to just include all TSE's, and rule them out from there with transmission studies and change policies there from, as opposed to doing just the opposite? The science of TSE's have been nothing more than a political circus since the beginning, and for anyone to still believe in this one strain, one group of bovines, in one geographical location, with only one age group of human TSE i.e. nvCJD myth, for anyone to believe this today only enhances to spreading of these human and animal TSE's. This is exactly why we have been in this quagmire.
The ones that believe that there is a spontaneous CJD in 85%+ of all cases of human TSE, and the ones that do not believe that cattle can have this same phenomenon, are two of the same, the industry, and so goes the political science aspect of this tobacco and or asbestos scenario i.e. follow the money. I could go into all angles of this man made nightmare, the real facts and science, for instance, the continuing rendering technology and slow cooking with low temps that brewed this stew up, and the fact that THE USA HAD THIS TECHNOLOGY FIRST AND SHIPPED IT TO THE U.K. SOME 5 YEARS BEFORE THE U.S. STARTED USING THE SAME TECHNOLOGY, to save on fuel cost. This is what supposedly amplified the TSE agent via sheep scrapie, and spread via feed in the U.K. bovine, and other countries exporting the tainted product. BUT most everyone ignores this fact, and the fact that the U.S. has been recycling more TSE, from more species with TSEs, than any other country documented, but yet, it's all spontaneous, and the rise in sporadic CJD in the U.S. is a happenstance of bad luck ??? I respectfully disagree. To top that all off, the infamous BSE-FIREWALL that the USDA always brags about was nothing more than ink on paper, and I can prove this. YOU can ignore it, but this is FACT (see source, as late as 2007, in one recall alone, some 10,000,000 MILLION POUNDS OF BANNED MAD COW FEED WENT OUT INTO COMMERCE TO BE FED OUT, and most was never recovered. This was banned blood laced, meat and bone meal. 2006 was a banner year for banned mad cow protein going into commerce in the U.S. (see source of FDA feed ban warning letter below). I stress that the August 4, 1997 USA mad cow feed ban and this infamous BSE firewall, was nothing more than ink on paper, it was never enforceable.
I propose that the current diagnostic criteria for human TSEs only enhances and helps the spreading of human TSE from the continued belief of the UKBSEnvCJD only theory in 2009. With all the science to date refuting it, to continue to validate this old myth, will only spread this TSE agent through a multitude of potential routes and sources i.e. consumption, medical i.e., surgical, blood, dental, endoscopy, optical, nutritional supplements, cosmetics etc. I propose as with Aguzzi, Asante, Collinge, Caughey, Deslys, Dormont, Gibbs, Gajdusek, Ironside, Manuelidis, Marsh, et al and many more, that the world of TSE Transmissible Spongiform Encephalopathy is far from an exact science, but there is enough proven science to date that this myth should be put to rest once and for all, and that we move forward with a new classification for human and animal TSE that would properly identify the infected species, the source species, and then the route. This would further have to be broken down to strain of species and then the route of transmission would further have to be broken down. Accumulation and Transmission are key to the threshold from sub-clinical to clinical disease, and key to all this, is to stop the amplification and transmission of this agent, the spreading of, no matter what strain. In my opinion, to continue with this myth that the U.K. strain of BSE one strain TSE in cows, and the nv/v CJD one strain TSE humans, and the one geographical location source i.e. U.K., and that all the rest of human TSE are just one single strain i.e. sporadic CJD, a happenstance of bad luck that just happens due to a twisted protein that just twisted the wrong way, IN 85%+ OF ALL HUMAN TSEs, when to date there are 6 different phenotypes of sCJD, and growing per Gambetti et al, and that no other animal TSE transmits to humans ??? With all due respect to all Scientist that believe this, I beg to differ. To continue with this masquerade will only continue to spread, expose, and kill, who knows how many more in the years and decades to come. ONE was enough for me, My Mom, hvCJD i.e. Heidenhain Variant CJD, DOD 12/14/97 confirmed, which is nothing more than another mans name added to CJD, like CJD itself, Jakob and Creutzfeldt, or Gerstmann-Straussler-Scheinker syndrome, just another CJD or human TSE, named after another human. WE are only kidding ourselves with the current diagnostic criteria for human and animal TSE, especially differentiating between the nvCJD vs the sporadic CJD strains and then the GSS strains and also the FFI fatal familial insomnia strains or the ones that mimics one or the other of those TSE? Tissue infectivity and strain typing of the many variants of the human and animal TSEs are paramount in all variants of all TSE. There must be a proper classification that will differentiate between all these human TSE in order to do this. With the CDI and other more sensitive testing coming about, I only hope that my proposal will some day be taken seriously. ...
please see history, and the ever evolving TSE science to date ;
RE-Monitoring the occurrence of emerging forms of Creutzfeldt-Jakob disease in the United States
Terry S. Singeltary, retired (medically), CJD WATCH
Submitted March 26, 2003
I lost my mother to hvCJD (Heidenhain Variant CJD). I would like to comment on the CDC's attempts to monitor the occurrence of emerging forms of CJD. Asante, Collinge et al [1] have reported that BSE transmission to the 129-methionine genotype can lead to an alternate phenotype that is indistinguishable from type 2 PrPSc, the commonest sporadic CJD. However, CJD and all human TSEs are not reportable nationally. CJD and all human TSEs must be made reportable in every state and internationally. I hope that the CDC does not continue to expect us to still believe that the 85%+ of all CJD cases which are sporadic are all spontaneous, without route/source. We have many TSEs in the USA in both animal and man. CWD in deer/elk is spreading rapidly and CWD does transmit to mink, ferret, cattle, and squirrel monkey by intracerebral inoculation. With the known incubation periods in other TSEs, oral transmission studies of CWD may take much longer. Every victim/family of CJD/TSEs should be asked about route and source of this agent. To prolong this will only spread the agent and needlessly expose others. In light of the findings of Asante and Collinge et al, there should be drastic measures to safeguard the medical and surgical arena from sporadic CJDs and all human TSEs. I only ponder how many sporadic CJDs in the USA are type 2 PrPSc?

Diagnosis and Reporting of Creutzfeldt-Jakob Disease
Terry S. Singeltary, Sr

JAMA. 2001;285(6):733-734. doi:10-1001/pubs.JAMA-ISSN-0098-7484-285-6-jlt0214 To the Editor: In their Research Letter, Dr Gibbons and colleagues1 reported that the annual US death rate due to Creutzfeldt-Jakob disease (CJD) has been stable since 1985. These estimates, however, are based only on reported cases, and do not include misdiagnosed or preclinical cases. It seems to me that misdiagnosis alone would drastically change these figures. An unknown number of persons with a diagnosis of Alzheimer disease in fact may have CJD, although only a small number of these patients receive the postmortem examination necessary to make this diagnosis. Furthermore, only a few states have made CJD reportable. Human and animal transmissible spongiform encephalopathies should be reportable nationwide and internationally.
Alzheimer’s disease and Transmissible Spongiform Encephalopathy prion disease, Iatrogenic, what if ?
Posted by flounder on 05 Nov 2014 at 21:27 GMT
Background
Alzheimer’s disease and Transmissible Spongiform Encephalopathy disease have both been around a long time, and was discovered in or around the same time frame, early 1900’s. Both diseases are incurable and debilitating brain disease, that are in the end, 100% fatal, with the incubation/clinical period of the Alzheimer’s disease being longer (most of the time) than the TSE prion disease. Symptoms are very similar, and pathology is very similar.
Methods
Through years of research, as a layperson, of peer review journals, transmission studies, and observations of loved ones and friends that have died from both Alzheimer’s and the TSE prion disease i.e. Heidenhain Variant Creutzfelt Jakob Disease CJD.
Results
I propose that Alzheimer’s is a TSE disease of low dose, slow, and long incubation disease, and that Alzheimer’s is Transmissible, and is a threat to the public via the many Iatrogenic routes and sources. It was said long ago that the only thing that disputes this, is Alzheimer’s disease transmissibility, or the lack of. The likelihood of many victims of Alzheimer’s disease from the many different Iatrogenic routes and modes of transmission as with the TSE prion disease.
Conclusions
There should be a Global Congressional Science round table event set up immediately to address these concerns from the many potential routes and sources of the TSE prion disease, including Alzheimer’s disease, and a emergency global doctrine put into effect to help combat the spread of Alzheimer’s disease via the medical, surgical, dental, tissue, and blood arena’s. All human and animal TSE prion disease, including Alzheimer’s should be made reportable in every state, and Internationally, WITH NO age restrictions. Until a proven method of decontamination and autoclaving is proven, and put forth in use universally, in all hospitals and medical, surgical arena’s, or the TSE prion agent will continue to spread. IF we wait until science and corporate politicians wait until politics lets science _prove_ this once and for all, and set forth regulations there from, we will all be exposed to the TSE Prion agents, if that has not happened already.

*** Transmission of Creutzfeldt-Jakob disease to a chimpanzee by electrodes contaminated during neurosurgery ***
Gibbs CJ Jr, Asher DM, Kobrine A, Amyx HL, Sulima MP, Gajdusek DC.
Laboratory of Central Nervous System Studies, National Institute of Neurological Disorders and Stroke, National Institutes of Health, Bethesda, MD 20892. Stereotactic multicontact electrodes used to probe the cerebral cortex of a middle aged woman with progressive dementia were previously implicated in the accidental transmission of Creutzfeldt-Jakob disease (CJD) to two younger patients. The diagnoses of CJD have been confirmed for all three cases. More than two years after their last use in humans, after three cleanings and repeated sterilisation in ethanol and formaldehyde vapour, the electrodes were implanted in the cortex of a chimpanzee. Eighteen months later the animal became ill with CJD. This finding serves to re-emphasise the potential danger posed by reuse of instruments contaminated with the agents of spongiform encephalopathies, even after scrupulous attempts to clean them.

Second death in France in a laboratory working on prions
Second lab worker with deadly prion disease prompts research pause in France
A lab worker died of prion disease in 2019, nine years after a lab accident.
BETH MOLE - 7/29/2021, 5:16 PM
A 2020 paper published in the New England Journal of Medicine left little doubt that Jaumain had been infected on the job. She had variant CJD, but since Europe’s ‘mad cow’ outbreak ended after 2000 and the disease virtually disappeared, the paper said it was virtually impossible for someone her age in France to contract food-borne vCJD.
Science also said two independent reports – one by government inspectors – had found no safety violations at the lab where Jaumain worked. The press release also noted that the inspectors concluded there was “the presence of a risk control culture within the research teams”. The Jaumain family’s lawyer called the neutrality of the reports into question, however.
At the same time, the government inspectors’ report also revealed that there had been at least 17 accidents among the 100 or so scientists and technicians in France working with prions in the previous decade, raising concerns about how effective this risk control culture is. Five of these occurred when workers “stabbed or cut themselves with contaminated syringes or blades”.

Friendly fire, pass it forward, they call it iatrogenic cjd, or what i call 'tse prion poker', are you all in $$$
all iatrogenic cjd is, is sporadic cjd, before the iatrogenic event is discovered, traced back, proven, documented, put into the academic domain, and then finally the public domain, this very seldom happens, thus problem solved, it's all sporadic cjd...

***> In conclusion, sensory symptoms and loss of reflexes in Gerstmann-Sträussler-Scheinker syndrome can be explained by neuropathological changes in the spinal cord.

vpspr, sgss, sffi, TSE, an iatrogenic by-product of gss, ffi, familial type prion disease, what it ???
Confucius is confused again.
I was just sitting and thinking about why there is no genetic link to some of these TSE prion sGSS, sFFi, and it’s really been working on my brain, and then it hit me today.
what if, vpspr, sgss, sffi, TSE prion disease, was a by-product from iatrogenic gss, ffi, familial type prion disease ???
it could explain the cases of no genetic link to the gss, ffi, familial type prion disease, to the family.
sporadic and familial is a red herring, in my opinion, and underestimation is spot on, due to the crude prehistoric diagnostic procedures and criteria and definition of a prion disease.
I say again, what if, iatrogenic, what if, with all these neurological disorders, with a common denominator that is increasingly showing up in the picture, called the prion.
I urge all scientist to come together here, with this as the utmost of importance about all these neurological disease that are increasingly showing up as a prion mechanism, to put on the front burners, the IATROGENIC aspect and the potential of transmission there from, with diseases/disease???
in question, by definition, could they be a Transmissible Spongiform Encephalopathy TSE prion type disease, and if so, what are the iatrogenic chances of transmission?
this is very important, and should be at the forefront of research, and if proven, could be a monumental breakthrough in science and battle against the spreading of these disease/diseases.
