New guidelines published for social workers around Creutzfeldt-Jakob Disease
Document aims to enhance professionals' awareness around the rare and rapidly deteriorating condition by Alex Turner on July 3, 2018 in Adults direction Photo: BillionPhotos.Com/Fotolia The government has published new guidance specifically aimed at social workers working with people with Creutzfeldt-Jakob Disease (CJD) and their families.
The document, issued by the Department for Health and Social Care, marks the first time that such guidance has been updated since 2003 – partly as a response to the changing legislative framework with the advent of the Care Act 2014.
CJD, which entered public consciousness after the BSE or ‘mad cow disease’ scandal of the late 1980s and early 90s, sees 100-130 new cases annually in the UK across all its sub-variants.
But the condition, which deteriorates quickly and can involve extreme behavioural disinhibition and is always fatal, is particularly distressing for those diagnosed with it and their families.
Rapid response The new guidance stresses the importance of responding “without delay” to cases involving people with CJD, who are often only diagnosed at an advanced stage and whose cognitive and other functions will decline rapidly.
“Social workers should avoid the use of standardised care packages and recognise the role families, communities and the adults’ own strengths and assets can play in meeting needs,” it says. A “whole family approach” should be adopted towards needs assessment, while care and support plans must be “creative” and geared towards fluctuations in need, the document adds in later sections.
It also underlines the importance of settling who is funding care, and appointing a key worker to coordinate a multi-disciplinary response, without delay.
The document signposts to a number of national resources, including individuals’ potential eligibility for the NHS’s Fast Track Provision, used where someone has a rapidly deteriorating condition that may be entering terminal phase.
It also points out the need for local authorities to ensure they issue sufficient advice around CJD and adult social care, noting a template published by Somerset council.
‘Empowering advice’ In an introduction to the guidance, the chief social worker for adults Lyn Romeo said she recognised that most social workers would never work with anyone with CJD.
But Romeo added that she hoped that for social workers who did find themselves supporting someone with CJD, the guidelines would prove “invaluable”.
“Social work practice is enabled by guidelines and the profession has long recognised that accurate information and advice are empowering – this is keenly felt by those social workers who encounter people whose health conditions require specialist consideration,” she said. “While each person is unique; those affected by CJD receive specialist diagnosis services, nationally coordinated health support and may have legal entitlements unique to this condition.”
CREUTZFELDT-JAKOB DISEASE: GUIDELINES FOR SOCIAL WORKERS IN ENGLAND
Peter Simcock, Jill Manthorpe, Selam Tesfamichael and Simon Mead
June 2018
Creutzfeldt-Jakob Disease (CJD) We provide services free of charge for people diagnosed with Creutzfeldt-Jakob Disease (CJD).
CJD was first identifed in the 1920s. It is a rare disease found in all parts of the world. The average age of sufferers is 65 years. Variant Creutzfeldt-Jakob Disease (vCJD) is a form of CJD that was identified in 1995. This disease affects people under the age of 50 years.
Many of the early signs of vCJD are like those that occur in other neurological and psychiatric illnesses. These can include : Mood swings Sleep problems Lack of interest in life Neglect of personal hygiene It may not be clear that the person has a serious disease of the nervous system for several months. You can find out more about the symptoms of vCJD on the NHS Direct website.
If you are concerned about yourself or someone you know, talk to your doctor. You can find out how we provide care and support by phoning us on 0300 123 2224.
It is important that everyone involved with the care of a person with vCJD works together and responds quickly to meet their needs and support their carers.
The professionals involved may include: Social Workers Doctors Nurses Physiotherapists Occupational Therapists The type of help most often asked for is: Social work and counselling Daily help and personal care Sitting service Respite care Financial advice Nursing care Continence aids Aids to daily living Adaptations to the home We will respond to anyone who contacts us about vCJD within two days.
One worker will be assigned to work with you. They will take responsibility for assessing and developing a care plan. They will co-ordinate services, information sharing and will contact the national CJD Surveillance Unit for advice.
If you care for someone with vCJD you can also ask to be assessed and services can be provided to support you in your caring role.
No charge will be made for any services provided to meet the needs arising from a diagnosis of CJD or vCJD.
The government has established a national fund to support the timely provision of care for people suffering from all forms of CJD. This money is not intended for routine care. The fund is administered by the CJD Surveillance Unit.

the tse prion aka mad cow type disease is not your normal pathogen.
The TSE prion disease survives ashing to 600 degrees celsius, that’s around 1112 degrees farenheit.
you cannot cook the TSE prion disease out of meat.
you can take the ash and mix it with saline and inject that ash into a mouse, and the mouse will go down with TSE.
Prion Infected Meat-and-Bone Meal Is Still Infectious after Biodiesel Production as well.
the TSE prion agent also survives Simulated Wastewater Treatment Processes.
IN fact, you should also know that the TSE Prion agent will survive in the environment for years, if not decades.
you can bury it and it will not go away.
The TSE agent is capable of infected your water table i.e. Detection of protease-resistant cervid prion protein in water from a CWD-endemic area.
it’s not your ordinary pathogen you can just cook it out and be done with.
that’s what’s so worrisome about Iatrogenic mode of transmission, a simple autoclave will not kill this TSE prion agent.

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.

In 1978, a rigorous programme was implemented to stop the spread of, and subsequently eradicate, sheep scrapie in Iceland. Affected flocks were culled, premises were disinfected and, after 2–3 years, restocked with lambs from scrapie-free areas. Between 1978 and 2004, scrapie recurred on 33 farms. Nine of these recurrences occurred 14–21 years after culling, apparently as the result of environmental contamination, but outside entry could not always be absolutely excluded. Of special interest was one farm with a small, completely self-contained flock where scrapie recurred 18 years after culling, 2 years after some lambs had been housed in an old sheephouse that had never been disinfected. Epidemiological investigation established with near certitude that the disease had not been introduced from the outside and it is concluded that the agent may have persisted in the old sheep-house for at least 16 years.

Using in vitro Prion replication for high sensitive detection of prions and prionlike proteins and for understanding mechanisms of transmission.
Claudio Soto Mitchell Center for Alzheimer's diseases and related Brain disorders, Department of Neurology, University of Texas Medical School at Houston.
Prion and prion-like proteins are misfolded protein aggregates with the ability to selfpropagate to spread disease between cells, organs and in some cases across individuals. I n T r a n s m i s s i b l e s p o n g i f o r m encephalopathies (TSEs), prions are mostly composed by a misfolded form of the prion protein (PrPSc), which propagates by transmitting its misfolding to the normal prion protein (PrPC). The availability of a procedure to replicate prions in the laboratory may be important to study the mechanism of prion and prion-like spreading and to develop high sensitive detection of small quantities of misfolded proteins in biological fluids, tissues and environmental samples. Protein Misfolding Cyclic Amplification (PMCA) is a simple, fast and efficient methodology to mimic prion replication in the test tube. PMCA is a platform technology that may enable amplification of any prion-like misfolded protein aggregating through a seeding/nucleation process. In TSEs, PMCA is able to detect the equivalent of one single molecule of infectious PrPSc and propagate prions that maintain high infectivity, strain properties and species specificity. Using PMCA we have been able to detect PrPSc in blood and urine of experimentally infected animals and humans affected by vCJD with high sensitivity and specificity. Recently, we have expanded the principles of PMCA to amplify amyloid-beta (Aβ) and alphasynuclein (α-syn) aggregates implicated in Alzheimer's and Parkinson's diseases, respectively. Experiments are ongoing to study the utility of this technology to detect Aβ and α-syn aggregates in samples of CSF and blood from patients affected by these diseases.
=========================
***Recently, we have been using PMCA to study the role of environmental prion contamination on the horizontal spreading of TSEs. These experiments have focused on the study of the interaction of prions with plants and environmentally relevant surfaces. Our results show that plants (both leaves and roots) bind tightly to prions present in brain extracts and excreta (urine and feces) and retain even small quantities of PrPSc for long periods of time. Strikingly, ingestion of prioncontaminated leaves and roots produced disease with a 100% attack rate and an incubation period not substantially longer than feeding animals directly with scrapie brain homogenate. Furthermore, plants can uptake prions from contaminated soil and transport them to different parts of the plant tissue (stem and leaves). Similarly, prions bind tightly to a variety of environmentally relevant surfaces, including stones, wood, metals, plastic, glass, cement, etc. Prion contaminated surfaces efficiently transmit prion disease when these materials were directly injected into the brain of animals and strikingly when the contaminated surfaces were just placed in the animal cage. These findings demonstrate that environmental materials can efficiently bind infectious prions and act as carriers of infectivity, suggesting that they may play an important role in the horizontal transmission of the disease.
========================
Since its invention 13 years ago, PMCA has helped to answer fundamental questions of prion propagation and has broad applications in research areas including the food industry, blood bank safety and human and veterinary disease diagnosis.

PPo4-4:
Survival and Limited Spread of TSE Infectivity after Burial
Discussion Classical scrapie is an environmentally transmissible disease because it has been reported in naïve, supposedly previously unexposed sheep placed in pastures formerly occupied by scrapie-infected sheep (4, 19, 20).
Although the vector for disease transmission is not known, soil is likely to be an important reservoir for prions (2) where – based on studies in rodents – prions can adhere to minerals as a biologically active form (21) and remain infectious for more than 2 years (22).
Similarly, chronic wasting disease (CWD) has re-occurred in mule deer housed in paddocks used by infected deer 2 years earlier, which was assumed to be through foraging and soil consumption (23).
Our study suggested that the risk of acquiring scrapie infection was greater through exposure to contaminated wooden, plastic, and metal surfaces via water or food troughs, fencing, and hurdles than through grazing.
Drinking from a water trough used by the scrapie flock was sufficient to cause infection in sheep in a clean building.
Exposure to fences and other objects used for rubbing also led to infection, which supported the hypothesis that skin may be a vector for disease transmission (9).
The risk of these objects to cause infection was further demonstrated when 87% of 23 sheep presented with PrPSc in lymphoid tissue after grazing on one of the paddocks, which contained metal hurdles, a metal lamb creep and a water trough in contact with the scrapie flock up to 8 weeks earlier, whereas no infection had been demonstrated previously in sheep grazing on this paddock, when equipped with new fencing and field furniture.
When the contaminated furniture and fencing were removed, the infection rate dropped significantly to 8% of 12 sheep, with soil of the paddock as the most likely source of infection caused by shedding of prions from the scrapie-infected sheep in this paddock up to a week earlier.
This study also indicated that the level of contamination of field furniture sufficient to cause infection was dependent on two factors: stage of incubation period and time of last use by scrapie-infected sheep.
Drinking from a water trough that had been used by scrapie sheep in the predominantly pre-clinical phase did not appear to cause infection, whereas infection was shown in sheep drinking from the water trough used by scrapie sheep in the later stage of the disease.
It is possible that contamination occurred through shedding of prions in saliva, which may have contaminated the surface of the water trough and subsequently the water when it was refilled.
Contamination appeared to be sufficient to cause infection only if the trough was in contact with sheep that included clinical cases.
Indeed, there is an increased risk of bodily fluid infectivity with disease progression in scrapie (24) and CWD (25) based on PrPSc detection by sPMCA.
Although ultraviolet light and heat under natural conditions do not inactivate prions (26), furniture in contact with the scrapie flock, which was assumed to be sufficiently contaminated to cause infection, did not act as vector for disease if not used for 18 months, which suggest that the weathering process alone was sufficient to inactivate prions.
PrPSc detection by sPMCA is increasingly used as a surrogate for infectivity measurements by bioassay in sheep or mice.
In this reported study, however, the levels of PrPSc present in the environment were below the limit of detection of the sPMCA method, yet were still sufficient to cause infection of in-contact animals.
In the present study, the outdoor objects were removed from the infected flock 8 weeks prior to sampling and were positive by sPMCA at very low levels (2 out of 37 reactions).
As this sPMCA assay also yielded 2 positive reactions out of 139 in samples from the scrapie-free farm, the sPMCA assay could not detect PrPSc on any of the objects above the background of the assay.
False positive reactions with sPMCA at a low frequency associated with de novo formation of infectious prions have been reported (27, 28).
This is in contrast to our previous study where we demonstrated that outdoor objects that had been in contact with the scrapie-infected flock up to 20 days prior to sampling harbored PrPSc that was detectable by sPMCA analysis [4 out of 15 reactions (12)] and was significantly more positive by the assay compared to analogous samples from the scrapie-free farm.
This discrepancy could be due to the use of a different sPMCA substrate between the studies that may alter the efficiency of amplification of the environmental PrPSc.
In addition, the present study had a longer timeframe between the objects being in contact with the infected flock and sampling, which may affect the levels of extractable PrPSc.
Alternatively, there may be potentially patchy contamination of this furniture with PrPSc, which may have been missed by swabbing.
The failure of sPMCA to detect CWD-associated PrP in saliva from clinically affected deer despite confirmation of infectivity in saliva-inoculated transgenic mice was associated with as yet unidentified inhibitors in saliva (29), and it is possible that the sensitivity of sPMCA is affected by other substances in the tested material.
In addition, sampling of amplifiable PrPSc and subsequent detection by sPMCA may be more difficult from furniture exposed to weather, which is supported by the observation that PrPSc was detected by sPMCA more frequently in indoor than outdoor furniture (12).
A recent experimental study has demonstrated that repeated cycles of drying and wetting of prion-contaminated soil, equivalent to what is expected under natural weathering conditions, could reduce PMCA amplification efficiency and extend the incubation period in hamsters inoculated with soil samples (30).
This seems to apply also to this study even though the reduction in infectivity was more dramatic in the sPMCA assays than in the sheep model.
Sheep were not kept until clinical end-point, which would have enabled us to compare incubation periods, but the lack of infection in sheep exposed to furniture that had not been in contact with scrapie sheep for a longer time period supports the hypothesis that prion degradation and subsequent loss of infectivity occurs even under natural conditions.
In conclusion, the results in the current study indicate that removal of furniture that had been in contact with scrapie-infected animals should be recommended, particularly since cleaning and decontamination may not effectively remove scrapie infectivity (31), even though infectivity declines considerably if the pasture and the field furniture have not been in contact with scrapie-infected sheep for several months. As sPMCA failed to detect PrPSc in furniture that was subjected to weathering, even though exposure led to infection in sheep, this method may not always be reliable in predicting the risk of scrapie infection through environmental contamination.
These results suggest that the VRQ/VRQ sheep model may be more sensitive than sPMCA for the detection of environmentally associated scrapie, and suggest that extremely low levels of scrapie contamination are able to cause infection in susceptible sheep genotypes.

O.05: Transmission of prions to primates after extended silent incubation periods: Implications for BSE and scrapie risk assessment in human populations

Prion diseases (PD) are the unique neurodegenerative proteinopathies reputed to be transmissible under field conditions since decades. The transmission of Bovine Spongiform Encephalopathy (BSE) to humans evidenced that an animal PD might be zoonotic under appropriate conditions. Contrarily, in the absence of obvious (epidemiological or experimental) elements supporting a transmission or genetic predispositions, PD, like the other proteinopathies, are reputed to occur spontaneously (atpical animal prion strains, sporadic CJD summing 80% of human prion cases). Non-human primate models provided the first evidences supporting the transmissibiity of human prion strains and the zoonotic potential of BSE. Among them, cynomolgus macaques brought major information for BSE risk assessment for human health (Chen, 2014), according to their phylogenetic proximity to humans and extended lifetime. We used this model to assess the zoonotic potential of other animal PD from bovine, ovine and cervid origins even after very long silent incubation periods.
*** We recently observed the direct transmission of a natural classical scrapie isolate to macaque after a 10-year silent incubation period,
***with features similar to some reported for human cases of sporadic CJD, albeit requiring fourfold long incubation than BSE. Scrapie, as recently evoked in humanized mice (Cassard, 2014),
***is the third potentially zoonotic PD (with BSE and L-type BSE),
***thus questioning the origin of human sporadic cases.
We will present an updated panorama of our different transmission studies and discuss the implications of such extended incubation periods on risk assessment of animal PD for human health.

Dietary exposure to bovine spongiform encephalopathy (BSE) contaminated bovine tissues is considered as the origin of variant Creutzfeldt Jakob (vCJD) disease in human. To date, BSE agent is the only recognized zoonotic prion. Despite the variety of Transmissible Spongiform Encephalopathy (TSE) agents that have been circulating for centuries in farmed ruminants there is no apparent epidemiological link between exposure to ruminant products and the occurrence of other form of TSE in human like sporadic Creutzfeldt Jakob Disease (sCJD). However, the zoonotic potential of the diversity of circulating TSE agents has never been systematically assessed. The major issue in experimental assessment of TSEs zoonotic potential lies in the modeling of the ‘species barrier‘, the biological phenomenon that limits TSE agents’ propagation from a species to another. In the last decade, mice genetically engineered to express normal forms of the human prion protein has proved essential in studying human prions pathogenesis and modeling the capacity of TSEs to cross the human species barrier.
To assess the zoonotic potential of prions circulating in farmed ruminants, we study their transmission ability in transgenic mice expressing human PrPC (HuPrP-Tg). Two lines of mice expressing different forms of the human PrPC (129Met or 129Val) are used to determine the role of the Met129Val dimorphism in susceptibility/resistance to the different agents.
These transmission experiments confirm the ability of BSE prions to propagate in 129M- HuPrP-Tg mice and demonstrate that Met129 homozygotes may be susceptible to BSE in sheep or goat to a greater degree than the BSE agent in cattle and that these agents can convey molecular properties and neuropathological indistinguishable from vCJD. However homozygous 129V mice are resistant to all tested BSE derived prions independently of the originating species suggesting a higher transmission barrier for 129V-PrP variant.
Transmission data also revealed that several scrapie prions propagate in HuPrP-Tg mice with efficiency comparable to that of cattle BSE. While the efficiency of transmission at primary passage was low, subsequent passages resulted in a highly virulent prion disease in both Met129 and Val129 mice.
Transmission of the different scrapie isolates in these mice leads to the emergence of prion strain phenotypes that showed similar characteristics to those displayed by MM1 or VV2 sCJD prion.
These results demonstrate that scrapie prions have a zoonotic potential and raise new questions about the possible link between animal and human prions.
why do we not want to do TSE transmission studies on chimpanzees $
5. A positive result from a chimpanzee challenged severly would likely create alarm in some circles even if the result could not be interpreted for man. I have a view that all these agents could be transmitted provided a large enough dose by appropriate routes was given and the animals kept long enough. Until the mechanisms of the species barrier are more clearly understood it might be best to retain that hypothesis.

Title: Transmission of scrapie prions to primate after an extended silent incubation period)
*** In complement to the recent demonstration that humanized mice are susceptible to scrapie, we report here the first observation of direct transmission of a natural classical scrapie isolate to a macaque after a 10-year incubation period. Neuropathologic examination revealed all of the features of a prion disease: spongiform change, neuronal loss, and accumulation of PrPres throughout the CNS.
*** This observation strengthens the questioning of the harmlessness of scrapie to humans, at a time when protective measures for human and animal health are being dismantled and reduced as c-BSE is considered controlled and being eradicated.
*** Our results underscore the importance of precautionary and protective measures and the necessity for long-term experimental transmission studies to assess the zoonotic potential of other animal prion strains.

4. The link between BSE and vCJD
4.29 The evidence discussed above that vCJD is caused by BSE seems overwhelming. Uncertainties exist about the cause of CJD in farmers, their wives and in several abattoir workers. It seems that farmers at least might be at higher risk than others in the general population. 1 Increased ascertainment (ie, increased identification of cases as a result of greater awareness of the condition) seems unlikely, as other groups exposed to risk, such as butchers and veterinarians, do not appear to have been affected. The CJD in farmers seems to be similar to other sporadic CJD in age of onset, in respect to glycosylation patterns, and in strain-typing in experimental mice. Some farmers are heterozygous for the methionine/valine variant at codon 129, and their lymphoreticular system (LRS) does not contain the high levels of PrPSc found in vCJD. It remains a remote possibility that when older people contract CJD from BSE the resulting phenotype is like sporadic CJD and is distinct from the vCJD phenotype in younger people...BSE INQUIRY

CDC CWD 2018 TRANSMISSION
*** The potential impact of prion diseases on human health was greatly magnified by the recognition that interspecies transfer of BSE to humans by beef ingestion resulted in vCJD. While changes in animal feed constituents and slaughter practices appear to have curtailed vCJD, there is concern that CWD of free-ranging deer and elk in the U.S. might also cross the species barrier. Thus, consuming venison could be a source of human prion disease. Whether BSE and CWD represent interspecies scrapie transfer or are newly arisen prion diseases is unknown. Therefore, the possibility of transmission of prion disease through other food animals cannot be ruled out. There is evidence that vCJD can be transmitted through blood transfusion. There is likely a pool of unknown size of asymptomatic individuals infected with vCJD, and there may be asymptomatic individuals infected with the CWD equivalent. These circumstances represent a potential threat to blood, blood products, and plasma supplies.

Cervid to human prion transmission
Kong, Qingzhong
Case Western Reserve University, Cleveland, OH, United States
Abstract
Prion disease is transmissible and invariably fatal. Chronic wasting disease (CWD) is the prion disease affecting deer, elk and moose, and it is a widespread and expanding epidemic affecting 22 US States and 2 Canadian provinces so far. CWD poses the most serious zoonotic prion transmission risks in North America because of huge venison consumption (>6 million deer/elk hunted and consumed annually in the USA alone), significant prion infectivity in muscles and other tissues/fluids from CWD-affected cervids, and usually high levels of individual exposure to CWD resulting from consumption of the affected animal among often just family and friends. However, we still do not know whether CWD prions can infect humans in the brain or peripheral tissues or whether clinical/asymptomatic CWD zoonosis has already occurred, and we have no essays to reliably detect CWD infection in humans. We hypothesize that:
(1) The classic CWD prion strain can infect humans at low levels in the brain and peripheral lymphoid tissues;
(2) The cervid-to-human transmission barrier is dependent on the cervid prion strain and influenced by the host (human) prion protein (PrP) primary sequence;
(3) Reliable essays can be established to detect CWD infection in humans;and
*** (4) CWD transmission to humans has already occurred.
We will test these hypotheses in 4 Aims using transgenic (Tg) mouse models and complementary in vitro approaches.
Aim 1 will prove that the classical CWD strain may infect humans in brain or peripheral lymphoid tissues at low levels by conducting systemic bioassays in a set of "humanized" Tg mouse lines expressing common human PrP variants using a number of CWD isolates at varying doses and routes. Experimental "human CWD" samples will also be generated for Aim 3.
Aim 2 will test the hypothesis that the cervid-to-human prion transmission barrier is dependent on prion strain and influenced by the host (human) PrP sequence by examining and comparing the transmission efficiency and phenotypes of several atypical/unusual CWD isolates/strains as well as a few prion strains from other species that have adapted to cervid PrP sequence, utilizing the same panel of humanized Tg mouse lines as in Aim 1.
Aim 3 will establish reliable essays for detection and surveillance of CWD infection in humans by examining in details the clinical, pathological, biochemical and in vitro seeding properties of existing and future experimental "human CWD" samples generated from Aims 1-2 and compare them with those of common sporadic human Creutzfeldt-Jakob disease (sCJD) prions.
Aim 4 will attempt to detect clinical CWD-affected human cases by examining a significant number of brain samples from prion-affected human subjects in the USA and Canada who have consumed venison from CWD-endemic areas utilizing the criteria and essays established in Aim 3. The findings from this proposal will greatly advance our understandings on the potential and characteristics of cervid prion transmission in humans, establish reliable essays for CWD zoonosis and potentially discover the first case(s) of CWD infection in humans.
Public Health Relevance There are significant and increasing human exposure to cervid prions because chronic wasting disease (CWD, a widespread and highly infectious prion disease among deer and elk in North America) continues spreading and consumption of venison remains popular, but our understanding on cervid-to-human prion transmission is still very limited, raising public health concerns. This proposal aims to define the zoonotic risks of cervid prions and set up and apply essays to detect CWD zoonosis using mouse models and in vitro methods. The findings will greatly expand our knowledge on the potentials and characteristics of cervid prion transmission in humans, establish reliable essays for such infections and may discover the first case(s) of CWD infection in humans.

This is a progress report of a project which started in 2009. 21 cynomolgus macaques were challenged with characterized CWD material from white-tailed deer (WTD) or elk by intracerebral (ic), oral, and skin exposure routes. Additional blood transfusion experiments are supposed to assess the CWD contamination risk of human blood product. Challenge materials originated from symptomatic cervids for ic, skin scarification and partially per oral routes (WTD brain). Challenge material for feeding of muscle derived from preclinical WTD and from preclinical macaques for blood transfusion experiments. We have confirmed that the CWD challenge material contained at least two different CWD agents (brain material) as well as CWD prions in muscle-associated nerves.
Here we present first data on a group of animals either challenged ic with steel wires or per orally and sacrificed with incubation times ranging from 4.5 to 6.9 years at postmortem. Three animals displayed signs of mild clinical disease, including anxiety, apathy, ataxia and/or tremor. In four animals wasting was observed, two of those had confirmed diabetes. All animals have variable signs of prion neuropathology in spinal cords and brains and by supersensitive IHC, reaction was detected in spinal cord segments of all animals. Protein misfolding cyclic amplification (PMCA), real-time quaking-induced conversion (RT-QuiC) and PET-blot assays to further substantiate these findings are on the way, as well as bioassays in bank voles and transgenic mice.
At present, a total of 10 animals are sacrificed and read-outs are ongoing. Preclinical incubation of the remaining macaques covers a range from 6.4 to 7.10 years. Based on the species barrier and an incubation time of > 5 years for BSE in macaques and about 10 years for scrapie in macaques, we expected an onset of clinical disease beyond 6 years post inoculation.

8. Even though human TSE‐exposure risk through consumption of game from European cervids can be assumed to be minor, if at all existing, no final conclusion can be drawn due to the overall lack of scientific data. In particular the US data do not clearly exclude the possibility of human (sporadic or familial) TSE development due to consumption of venison. The Working Group thus recognizes a potential risk to consumers if a TSE would be present in European cervids. It might be prudent considering appropriate measures to reduce such a risk, e.g. excluding tissues such as CNS and lymphoid tissues from the human food chain, which would greatly reduce any potential risk for consumers. However, it is stressed that currently, no data regarding a risk of TSE infections from cervid products are available.
snip...
The tissue distribution of infectivity in CWD‐infected cervids is now known to extend beyond CNS and lymphoid tissues. While the removal of these specific tissues from the food chain would reduce human dietary exposure to infectivity, exclusion from the food chain of the whole carcass of any infected animal would be required to eliminate human dietary exposure.

Volume 2: Science
4. The link between BSE and vCJD
4.29 The evidence discussed above that vCJD is caused by BSE seems overwhelming. Uncertainties exist about the cause of CJD in farmers, their wives and in several abattoir workers. It seems that farmers at least might be at higher risk than others in the general population. 1 Increased ascertainment (ie, increased identification of cases as a result of greater awareness of the condition) seems unlikely, as other groups exposed to risk, such as butchers and veterinarians, do not appear to have been affected. The CJD in farmers seems to be similar to other sporadic CJD in age of onset, in respect to glycosylation patterns, and in strain-typing in experimental mice. Some farmers are heterozygous for the methionine/valine variant at codon 129, and their lymphoreticular system (LRS) does not contain the high levels of PrPSc found in vCJD. It remains a remote possibility that when older people contract CJD from BSE the resulting phenotype is like sporadic CJD and is distinct from the vCJD phenotype in younger people...BSE INQUIRY
Summary and Recommendation:
snip...
Health Portfolio partners were recently made aware of initial findings from a research project led by a CFIA scientist that have demonstrated that cynomolgus macaques can be infected via intracranial exposure and oral gavage with CWD infected muscle.
These findings suggest that CWD, under specific experimental conditions, has the potential to cross the human species barrier, including by enteral feeding of CWD infected muscle.
*** WDA 2016 NEW YORK ***
We found that CWD adapts to a new host more readily than BSE and that human PrP was unexpectedly prone to misfolding by CWD prions.
In addition, we investigated the role of specific regions of the bovine, deer and human PrP protein in resistance to conversion by prions from another species.
***We have concluded that the human protein has a region that confers unusual susceptibility to conversion by CWD prions.
Student Presentations Session 2
The species barriers and public health threat of CWD and BSE prions
Ms. Kristen Davenport1, Dr. Davin Henderson1, Dr. Candace Mathiason1, Dr. Edward Hoover1 1Colorado State University
Chronic wasting disease (CWD) is spreading rapidly through cervid populations in the USA. Bovine spongiform encephalopathy (BSE, mad cow disease) arose in the 1980s because cattle were fed recycled animal protein.
These and other prion diseases are caused by abnormal folding of the normal prion protein (PrP) into a disease causing form (PrPd), which is pathogenic to nervous system cells and can cause subsequent PrP to misfold. CWD spreads among cervids very efficiently, but it has not yet infected humans. On the other hand, BSE was spread only when cattle consumed infected bovine or ovine tissue, but did infect humans and other species.
The objective of this research is to understand the role of PrP structure in cross-species infection by CWD and BSE. To study the propensity of each species’ PrP to be induced to misfold by the presence of PrPd from verious species, we have used an in vitro system that permits detection of PrPd in real-time.
We measured the conversion efficiency of various combinations of PrPd seeds and PrP substrate combinations.
We observed the cross-species behavior of CWD and BSE, in addition to feline-adapted CWD and BSE. We found that CWD adapts to a new host more readily than BSE and that human PrP was unexpectedly prone to misfolding by CWD prions. In addition, we investigated the role of specific regions of the bovine, deer and human PrP protein in resistance to conversion by prions from another species.
***We have concluded that the human protein has a region that confers unusual susceptibility to conversion by CWD prions. CWD is unique among prion diseases in its rapid spread in natural populations. BSE prions are essentially unaltered upon passage to a new species, while CWD adapts to the new species. This adaptation has consequences for surveillance of humans exposed to CWD.

CDC CWD 2018 TRANSMISSION
*** The potential impact of prion diseases on human health was greatly magnified by the recognition that interspecies transfer of BSE to humans by beef ingestion resulted in vCJD. While changes in animal feed constituents and slaughter practices appear to have curtailed vCJD, there is concern that CWD of free-ranging deer and elk in the U.S. might also cross the species barrier. Thus, consuming venison could be a source of human prion disease. Whether BSE and CWD represent interspecies scrapie transfer or are newly arisen prion diseases is unknown. Therefore, the possibility of transmission of prion disease through other food animals cannot be ruled out. There is evidence that vCJD can be transmitted through blood transfusion. There is likely a pool of unknown size of asymptomatic individuals infected with vCJD, and there may be asymptomatic individuals infected with the CWD equivalent. These circumstances represent a potential threat to blood, blood products, and plasma supplies.
Transmission Studies
Mule deer transmissions of CWD were by intracerebral inoculation and compared with natural cases {the following was written but with a single line marked through it ''first passage (by this route)}...TSS
resulted in a more rapidly progressive clinical disease with repeated episodes of synocopy ending in coma. One control animal became affected, it is believed through contamination of inoculum (?saline). Further CWD transmissions were carried out by Dick Marsh into ferret, mink and squirrel monkey. Transmission occurred in ALL of these species with the shortest incubation period in the ferret.

Prion Infectivity in Fat of Deer with Chronic Wasting Disease▿
Brent Race#, Kimberly Meade-White#, Richard Race and Bruce Chesebro* + Author Affiliations
In mice, prion infectivity was recently detected in fat. Since ruminant fat is consumed by humans and fed to animals, we determined infectivity titers in fat from two CWD-infected deer. Deer fat devoid of muscle contained low levels of CWD infectivity and might be a risk factor for prion infection of other species.
Prions in Skeletal Muscles of Deer with Chronic Wasting Disease
Here bioassays in transgenic mice expressing cervid prion protein revealed the presence of infectious prions in skeletal muscles of CWD-infected deer, demonstrating that humans consuming or handling meat from CWD-infected deer are at risk to prion exposure.

Dear Sir/Madam,
In the Archives of Neurology you quoted (the abstract of which was attached to your email), we did not say CWD in humans will present like variant CJD. That assumption would be wrong. I encourage you to read the whole article and call me if you have questions or need more clarification (phone: 404-639-3091). Also, we do not claim that "no-one has ever been infected with prion disease from eating venison." Our conclusion stating that we found no strong evidence of CWD transmission to humans in the article you quoted or in any other forum is limited to the patients we investigated.

key word here is 'reported'. science has shown that CWD in humans will look like sporadic CJD. SO, how can one assume that CWD has not already transmitted to humans? they can't, and it's as simple as that. from all recorded science to date, CWD has already transmitted to humans, and it's being misdiagnosed as sporadic CJD. ...terry
*** LOOKING FOR CWD IN HUMANS AS nvCJD or as an ATYPICAL CJD, LOOKING IN ALL THE WRONG PLACES $$$ ***
*** These results would seem to suggest that CWD does indeed have zoonotic potential, at least as judged by the compatibility of CWD prions and their human PrPC target. Furthermore, extrapolation from this simple in vitro assay suggests that if zoonotic CWD occurred, it would most likely effect those of the PRNP codon 129-MM genotype and that the PrPres type would be similar to that found in the most common subtype of sCJD (MM1).***

Aims: Sporadic Creutzfeldt-Jakob disease (sCJD), the most common human prion disease, is transmissible by neuroinvasive iatrogenic routes due to abundant prion infectivity in the central nervous system (CNS). The disease-associated prion protein (PrPSc) and its infectivity have never been detected in skin from sCJD patients; however, some epidemiological studies have associated sCJD risk with skin-involved non-CNS surgeries. The aims of our study were to explore potential prion seeding activity and infectivity of skin and the feasibility of skin-based CJD diagnosis.
Methods: Skin samples were collected at autopsy or biopsy from twenty-one sCJD, two variant CJD, and fifteen non-CJD patients and analysed by Western blotting and real-time quaking-induced conversion (RT- QulC) for PrPSc. Infectivity of skin from two sCJD patients was determined by bioassay using two lines of humanized transgenic (Tg) mice.
Results: Western blotting demonstrated PrPSc in the skin of one of five deceased sCJD patients examined. However, the more sensitive RT-QuIC assay detected prion-seeding activity in skin from all 23 CJD decedents but not in non-CJD controls, indicating preliminary ClD diagnostic sensitivities and specificities of 100% (95% confidence intervals of 85-100%, and 78-100%, respectively). Although sCJD skins contained ~102-105-fold lower RT-QuIC seeding activity than sCJD brains, ten out of twelve mice from two Tg mouse lines inoculated with skin homogenates of two patients with two different subtypes of sCJD succumbed to prion disease within 450 days after inoculation.
Conclusions: O sCJD patients' skin may contain both detectable prion seeding activity and transmissible prions. Our findings not only suggest a new basis for diagnostic sCJD testing, but also raise concerns about the potential for iatrogenic sCJD transmission via skin.

*** PrPSc in the skin of CJD patients
Unexpectedly, our latest preliminary study identified two types of PK-resistant PrP molecules [with gel mobility similar to the PrPSc types 1 and 2 from the brain of sporadic CJD (sCJD)] in the fibroblast cells extracted from the skin of clinical sCJD patients and asymptomatic subjects carrying PrP mutations linked to familial CJD (fCJD). We also detected PrPSc in the skin of humanized transgenic (Tg) mice inoculated intracerebrally with a human prion. Moreover, prion infectivity has been observed in the skin of infected greater kudu (Cunningham et al., 2004) and a murine prion inoculated to mice via skin scarification can not only propagate in the skin, but also spread to the brain to cause prion disease (Wathne et al., 2012). We hypothesize that the skin of patients with prion disease harbors prion infectivity and the presence of PK-resistant PrP in the skin is a novel diagnostic marker for preclinical CJD patients.
A Kiss of a Prion: New Implications for Oral Transmissibility
The transmissibility of scrapie among sheep (intraspecies) is well recognized. It must be emphasized that horizontal transfer (from one individual to another) of scrapie is the main route of infection, because vertical transmission of disease from mother to offspring via milk or placental tissue occurs infrequently. Thus, in view of the report by Maddison et al, the oral transmissibility of prions among sheep may serve as a major route for horizontal scrapie transfer. This occurrence is plausible because sheep often lick each other. Maddison et al [10] indicate that, because of the similarities in prion tissue distribution, their implications for the oral transmission of ovine scrapie might be true for other prion diseases, such as cervid chronic wasting disease and human vCJD. If this is true for humans, a kiss of a prion may sometimes have lethal consequences.
PERSON TO PERSON TRANSMISSION OF THE TSE PRION DISEASE, never say never. as the disease mutates, it becomes more virulent in some cases, and cwd is efficiently transmitted from cervid to cervid. there are now multiple strains of CWD in cervids, as with the TSE prion disease in bovine, sheep and goats, and we now have the atypical TSE in these species, that have mutated, and some strains _have_ become more virulent. we now have younger humans dying from the TSE prion disease, with shorter incubation period, and that are much younger. human to human casual transmission of the TSE prion disease...again, never say never. ...TSS
see more here;
The occurrence of the disease in a patient who had contact with cases of familial C.J.D., but was not genetically related, has been described in Chile (Galvez et al., 1980) and in France (Brown et al., 1979b). In Chile the patient was related by marriage, but with no consanguinity, and had social contact with subsequently affected family members for 13 years before developing the disease. The contact case in France also married into a family in which C.J.D. was prevalent and had close contact with an affected member. In neither instance did the spouse of the non-familial case have the disease. The case described in this report was similarly related to affected family members and social contact had occurred for 20 years prior to developing C.J.D. If contact transmission had occurred, the minimum transmission period would be 11 years. Contact between sporadic cases has not been described and it is remarkable that possible contact transmissions have all been with familial cases. No method of transmission by casual social contact has been suggested.
***The occurrence of contact cases raises the possibility that transmission in families may be effected by an unusually virulent strain of the agent.

Skin as a Potential Source of Prion Infectivity Mammalian skin is composed of different strata and cell types, which are both innervated and carry blood vessels. There is therefore the potential for skin to harbor prions and facilitate its excretion into the environment. Cunningham and coworkers demonstrated the presence of prion infectivity in the skin of BSE-affected kudu.87 Subsequently, Thomzig et al. used a rodent model to demonstrate that skin-associated prions could be identified from late preclinical stages of disease for both scrapie and BSE,88 estimating that there is likely to be 5,000–10,000 times less prion in the skin of hamsters challenged with scrapie than in the brains of those same animals. This study also demonstrated the presence of prions in the skin of sheep during the late stages of naturally acquired scrapie where PrPSc was generally associated with small nerve fibers within the dermis. More recently, PrPSc was found within the skin of a vCJD patient.89 In addition, cervine CWD prions have been found within antler velvet,90 a vascularized skin layer covering the developing antler of male deer, which is shed after the ossification of antlers.
Skin may therefore represent another route by which prions contaminate the environment. Mechanisms of prion shedding from this organ could include natural sloughing of skin, abrasions of the skin and, in the case of sheep, skin cuts and nicks that are introduced during shearing.

In the event of an accidental exposure or injury, the protocol is as follows:
1. Modes of Transmission:
- Skin puncture or injection
- Ingestion
- Contact with mucous membranes (eyes, nose, mouth)
- Contact with non-intact skin
- Exposure to aerosols
2. First Aid: There is no evidence of occupational transmission of prion disease to healthcare workers. Perform first aid as self-care according to the type of exposure/ injury.
a. First Aid for an unbroken Skin Exposure: Wash with soap and abundant quantities of warm water (avoid scrubbing), rinse, and dry. Apply for 1 minute, 0.1N Sodium Hydroxide (NaOH) or a 1:10 dilution of bleach (sodiumhypochlorite).
- When decontaminating with 0.1N NaOH or sodium hypochlorite, a face shield and eye goggles or eye goggles with mask should be worn for protection. It is important to decontaminate the wound with the appropriate agent for the appropriate length of time in order to denature the protein as soon as possible. See the special precautions for NaOH below.
- After decontamination, rinse well with soap and water to neutralize the base.
- Bring the 0.1N sodium hydroxide SDS to the ED
b. First Aid for lacerations or needlestick injuries: Gently encourage bleeding; wash (avoid scrubbing) with warm soapy water, rinse, dry and cover with a waterproof dressing. Further treatment (e.g. sutures) should be appropriate to the type of injury.
c. First Aid for splashes to the Eye, Nose or Mouth: Immediately flush the area with running water or normal saline. Continue washing for 15 minutes. Do not use sodium hydroxide or sodium hypochlorite in or around your eyes. Do not rub or keep eyes closed.
d. Following the administration of first aid, the employee will:
- Inform your supervisor of the exposure.
- Remove any garments that may have become soiled/contaminated with prions or NaOH, and place them in a double plastic bag. Close the bag securely, label it as contaminated, and wash your hands thoroughly.
- Identify any equipment involved in the exposure and the mechanism of exposure. Make sure that the area has been secured and that notification of contamination has been posted to prevent other individuals from entering the area.
- If you need immediate care for your injury, proceed to the Emergency Department(ED). When you injury is stable, Contact the Needlestick Exposure Hotline (415-353-7842) to report the exposure. The injured employee will need to follow up in the UCSF Occupational Health Clinic. Be sure to go to the clinic for medical evaluation and complete all necessary workers’ compensation paperwork.
e. Splash Affecting Garments, remove garments that may have become soiled or contaminated and place them in a double biohazard red plastic bag. Disposable gloves and gowns should dispose of by incineration, according to World Health Organization guidelines.

She left 6 Kids and a Husband.The Purpose of this web is to give information in Spanish to the Hispanic community, and to all the community who want's information about this terrible disease.- Physician Discharge Summary, Parkland Hospital, Dallas Texas Admit Date: 12/29/2009 Discharge Date: 1/20/2010 Attending Provider: Greenberg, Benjamin Morris; General Neurology Team: General Neurology Team Linda was a Hispanic female with no past medical history presents with 14 months of incresing/progressive altered mental status, generalized weakness, inability to walk, loss of appetite, inability to speak, tremor and bowel/blader incontinence.She was, in her usual state of health up until February, 2009, when her husbans notes that she began forgetting things like names and short term memories. He also noticed mild/vague personality changes such as increased aggression. In March, she was involved in a hit and run MVA,although she was not injured. The police tracked her down and ticketed her. At that time, her son deployed to Iraq with the Army and her husband assumed her mentation changes were due to stress over these two events. Also in March, she began to have weakness in her legs, making it difficult to walk. Over the next few months, her mentation and personality changes worsened, getting to a point where she could no longer recognized her children. She was eating less and less. She was losing more weight. In the last 2-3 months, she reached the point where she could not walk without an assist, then 1 month ago, she stopped talking, only making grunting/aggressive sounds when anyone came near her. She also became both bowel and bladder incontinent, having to wear diapers. Her '"tremor'" and body jerks worsened and her hands assumed a sort of permanent grip position, leading her family to put tennis balls in her hands to protect her fingers. The husband says that they have lived in Nebraska for the past 21 years. They had seen a doctor there during the summer time who prescribed her Seroquel and Lexapro, Thinking these were sx of a mood disorder. However, the medications did not help and she continued to deteriorate clinically. Up until about 6 years ago, the pt worked at Tyson foods where she worked on the assembly line, slaughtering cattle and preparing them for packaging. She was exposed to brain and spinal cord matter when she would euthanize the cattle. The husband says that he does not know any fellow workers with a similar illness. He also says that she did not have any preceeding illness or travel.

En terminos Médicos ella prensento un desorden mental con ansiedad y pérdida del habla y contracciones en los musculos que la inmobilizaba. Esto llevo a los médicos a predecir el diagnostico de CJD esporádico o variante, después de reuniones familiares se llego al acuerdo de no proseguir con los exámenes indicados como una biopsia cerebral debido al estado de debilidad y gravedad de ella, pues peligraba su vida y por consiguiente peligraban los médicos que le aplicarian el exámen ya que es demasiado contagioso.
Ella fué dada de alta con el diagnostico de CJD Esporádico, sin medicamento y con pocas esperanzas y semanas de vida.

Diagnosis and Reporting of Creutzfeldt-Jakob Disease
Singeltary, Sr et al. JAMA.2001; 285: 733-734. Vol. 285 No. 6, February 14, 2001 JAMA Diagnosis and Reporting of Creutzfeldt-Jakob Disease
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.

Tracking spongiform encephalopathies in North America
Xavier Bosch
Published: August 2003
Summary;
“My name is Terry S Singeltary Sr, and I live in Bacliff, Texas. I lost my mom to hvCJD (Heidenhain variant CJD) and have been searching for answers ever since. What I have found is that we have not been told the truth. CWD in deer and elk is a small portion of a much bigger problem.”
49-year-old Singeltary is one of a number of people who have remained largely unsatisfied after being told that a close relative died from a rapidly progressive dementia compatible with spontaneous Creutzfeldt-Jakob disease (CJD). So he decided to gather hundreds of documents on transmissible spongiform encephalopathies (TSE) and realised that if Britons could get variant CJD from bovine spongiform encephalopathy (BSE), Americans might get a similar disorder from chronic wasting disease (CWD) the relative of mad cow disease seen among deer and elk in the USA. Although his feverish search did not lead him to the smoking gun linking CWD to a similar disease in North American people, it did uncover a largely disappointing situation.
Singeltary was greatly demoralised at the few attempts to monitor the occurrence of CJD and CWD in the USA. Only a few states have made CJD reportable. Human and animal TSEs should be reportable nationwide and internationally, he complained in a letter to the Journal of the American Medical Association (JAMA 2003; 285: 733). "I hope that the CDC does not continue to expect us to still believe that the 85% plus of all CJD cases which are sporadic are all spontaneous, without route or source."
Until recently, CWD was thought to be confined to the wild in a small region in Colorado. But since early 2002, it has been reported in other areas, including Wisconsin, South Dakota, and the Canadian province of Saskatchewan. Indeed, the occurrence of CWD in states that were not endemic previously increased concern about a widespread outbreak and possible transmission to people and cattle.
To date, experimental studies have proven that the CWD agent can be transmitted to cattle by intracerebral inoculation and that it can cross the mucous membranes of the digestive tract to initiate infection in lymphoid tissue before invasion of the central nervous system. Yet the plausibility of CWD spreading to people has remained elusive.
Part of the problem seems to stem from the US surveillance system. CJD is only reported in those areas known to be endemic foci of CWD. Moreover, US authorities have been criticised for not having performed enough prionic tests in farm deer and elk.
Although in November last year the US Food and Drug Administration issued a directive to state public-health and agriculture officials prohibiting material from CWD-positive animals from being used as an ingredient in feed for any animal species, epidemiological control and research in the USA has been quite different from the situation in the UK and Europe regarding BSE.
"Getting data on TSEs in the USA from the government is like pulling teeth", Singeltary argues. "You get it when they want you to have it, and only what they want you to have."
Norman Foster, director of the Cognitive Disorders Clinic at the University of Michigan (Ann Arbor, MI, USA), says that "current surveillance of prion disease in people in the USA is inadequate to detect whether CWD is occurring in human beings"; adding that, "the cases that we know about are reassuring, because they do not suggest the appearance of a new variant of CJD in the USA or atypical features in patients that might be exposed to CWD. However, until we establish a system that identifies and analyses a high proportion of suspected prion disease cases we will not know for sure". The USA should develop a system modelled on that established in the UK, he points out.
Ali Samii, a neurologist at Seattle VA Medical Center who recently reported the cases of three hunters "two of whom were friends" who died from pathologically confirmed CJD, says that "at present there are insufficient data to claim transmission of CWD into humans"; adding that "[only] by asking [the questions of venison consumption and deer/elk hunting] in every case can we collect suspect cases and look into the plausibility of transmission further". Samii argues that by making both doctors and hunters more aware of the possibility of prions spreading through eating venison, doctors treating hunters with dementia can consider a possible prion disease, and doctors treating CJD patients will know to ask whether they ate venison.
CDC spokesman Ermias Belay says that the CDC "will not be investigating the [Samii] cases because there is no evidence that the men ate CWD-infected meat". He notes that although "the likelihood of CWD jumping the species barrier to infect humans cannot be ruled out 100%" and that "[we] cannot be 100% sure that CWD does not exist in humans& the data seeking evidence of CWD transmission to humans have been very limited".

Terry S. Singeltary, retired (medically) CJD WATCH
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?

First, I applaud Nature, the Scientist and Authors of the Nature paper, for bringing this important finding to the attention of the public domain, and the media for printing said findings.
Secondly, it seems once again, politics is getting in the way possibly of more important Transmissible Spongiform Encephalopathy TSE Prion scientific findings. findings that could have great implications for human health, and great implications for the medical surgical arena. but apparently, the government peer review process, of the peer review science, tries to intervene again to water down said disturbing findings.
where have we all heard this before? it's been well documented via the BSE Inquiry. have they not learned a lesson from the last time?
we have seen this time and time again in England (and other Country's) with the BSE mad cow TSE Prion debacle.
That 'anonymous' Lancet editorial was disgraceful. The editor, Dick Horton is not a scientist.
The pituitary cadavers were very likely elderly and among them some were on their way to CJD or Alzheimer's. Not a bit unusual. Then the recipients, who got pooled extracts injected from thousands of cadavers, were 100% certain to have been injected with both seeds. No surprise that they got both diseases going after thirty year incubations.
That the UK has a "system in place to assist science journalists" to squash embargoed science reports they find 'alarming' is pathetic.
Sounds like the journalists had it right in the first place: 'Alzheimer's may be a transmissible infection' in The Independent to 'You can catch Alzheimer's' in The Daily Mirror or 'Alzheimer's bombshell' in The Daily Express
if not for the journalist, the layperson would not know about these important findings.
where would we be today with sound science, from where we were 30 years ago, if not for the cloak of secrecy and save the industry at all cost mentality?
when you have a peer review system for science, from which a government constantly circumvents, then you have a problem with science, and humans die.
to date, as far as documented body bag count, with all TSE prion named to date, that count is still relatively low (one was too many in my case, Mom hvCJD), however that changes drastically once the TSE Prion link is made with Alzheimer's, the price of poker goes up drastically.
so, who makes that final decision, and how many more decades do we have to wait?
the iatrogenic mode of transmission of TSE prion, the many routes there from, load factor, threshold from said load factor to sub-clinical disease, to clinical disease, to death, much time is there to spread a TSE Prion to anywhere, but whom, by whom, and when, do we make that final decision to do something about it globally? how many documented body bags does it take? how many more decades do we wait? how many names can we make up for one disease, TSE prion?
Professor Collinge et al, and others, have had troubles in the past with the Government meddling in scientific findings, that might in some way involve industry, never mind human and or animal health.
FOR any government to continue to circumvent science for monetary gain, fear factor, or any reason, shame, shame on you.
in my opinion, it's one of the reasons we are at where we are at to date, with regards to the TSE Prion disease science i.e. money, industry, politics, then comes science, in that order.
greed, corporate, lobbyist there from, and government, must be removed from the peer review process of sound science, it's bad enough having them in the pharmaceutical aspect of healthcare policy making, in my opinion.
my mother died from confirmed hvCJD, and her brother (my uncle) Alzheimer's of some type (no autopsy?). just made a promise, never forget, and never let them forget, before I do.
I kindly wish to remind the public of the past, and a possible future we all hopes never happens again. ...

Alzheimer’s disease and Transmissible Spongiform Encephalopathy prion disease, Iatrogenic, what if ?
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.

Hello Nicole,
by all means, please do use my poster. but I thought this was already taken care of, and I could not attend for my poster presentation, therefore, it was not going to be presented. I have some health issues and could not make the trip.
please see old correspondence below...

#0670: Transmissible Spongiform encephalopathy (TSE) animal and human TSE in North America update October 2009
Authors: T. Singeltary; Bacliff, TX/US
Title: Transmissible Spongiform encephalopathy (TSE) animal and human TSE in North America update October 2009
Body: Background
An update on atypical BSE and other TSE in North America. Please remember, the typical U.K. c-BSE, the atypical l-BSE (BASE), and h-BSE have all been documented in North America, along with the typical scrapie's, and atypical Nor-98 Scrapie, and to date, 2 different strains of CWD, and also TME. All these TSE in different species have been rendered and fed to food producing animals for humans and animals in North America (TSE in cats and dogs ?), and that the trading of these TSEs via animals and products via the USA and Canada has been immense over the years, decades.
Methods
12 years independent research of available data
Results
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.
Conclusion
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. Restricting the reporting of CJD and or any human TSE is NOT scientific. Iatrogenic CJD knows NO age group, TSE knows no boundaries.
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.
