Breakthrough in cancer research

‘Breakthrough’ method rids patients of advanced cancer - Healthzone.ca
Excerpt:

Kalos explains that the technique works much like a vaccine, training
the immune system to target cancer cells, just as inoculations coax it
to fight off viruses.



To do this, researchers isolated
immunological T-cells from the blood of the three leukemia patients and
genetically reprogrammed them using a virus vector that inserted a new
gene into their DNA.



This gene coaxed the T-cells to
create an antibody — known as chimeric antigen receptor or CAR — that
would specifically target structures on the surface of cancer cells.



The newly armed T-cells were then
injected back into the respective patients where they sought out and
bound themselves to the cancer cells and killed them.



More importantly, however, the
reprogrammed hunters caused other T-cells to multiply each time they
attacked, creating more killers with each slain cancer cell.



“Within three weeks the tumours had
been blown away, in a way that was much more violent than we ever
expected,” Dr. Carl June, a senior study author, said in a statement.



“In addition to an extensive capacity
for self-replication the infused T-cells are serial killers. On average
each infused T-cell led to the killing of thousands of tumour cells,”
said June, a University of Pennsylvania pathologist.



It’s estimated the scant number of
T-cells originally injected into the patients killed more than two
pounds of tumour cells in each of the men, whose blood and bone marrow
were replete with cancer.



After a year, microscopic analysis of their blood could find no trace of cancerous cells, Kalos says.



“I am still trying to grasp the
enormity of what I am part of and of what the results will mean to
countless others with (leukemia) or other forms of cancer,” one of the
patients, none of whom were named, said in a written statement.



Kalos says it appears that, like a
vaccine, the T-cells also left the patients with a lingering protection,
which would reactivate the immunological attack if cancer returned.



“If leukemia does come back, those T-cells (appear to be) armed and ready to eliminate it,” he said.

Measles and Mumps rear their ugly heads in Ontario

Doctors warn that measles, mumps going around - Healthzone.ca
I'm guessing that this is at least in part thanks to the ignorance spread by the anti-vaxxers.
If you aren't already immune, please get your shots to help protect yourself, your friends and family, and the public in general.

Excerpt:
If in doubt of your immunization status, get another needle, King advised. A blood test will also tell you if you’re protected.

“There is never any harm in receiving another dose of measles, mumps
and rubella vaccine if you simply do not know,” King said. Extra doses
are generally not considered harmful, she said.


Later this year the province is rolling out an integrated infectious
disease and immunization registry, called Panorama, which will compile
existing data and create a vaccination database accessible by health
professionals and, one day, the public. The project is expected to take
years, and eventually link to other provincial systems.


King called Panorama, related to the broader eHealth program, a
“really important advancement” in public health and emergency
preparedness.


To be fully vaccinated requires two doses of the measles, mumps and
rubella (MMR) vaccine, which is publicly funded and delivered for free
to Ontario residents. The province provides 14 vaccines against 17
illnesses. Those born before 1970 probably became immune to those
illnesses by exposure.


Measles is highly contagious, spread by contact, coughing and
sneezing. Symptoms of measles include rash, high fever and watery eyes.


Mumps, a viral infection of the salivary glands, is rare. Symptoms of
the mumps include swelling and pain in the side of the jaw, fever,
headache, fatigue, and loss of appetite.

Smokers in the North, Drinkers in the Southwest

Drinking and marijuana use on the rise in Ontario: Survey - Healthzone.ca

A daily beer or cocktail could be turning into a habit for more
people in Ontario and marijuana use is also growing, according to a new
survey.


The survey released today by the Centre for Addiction and Mental
Health suggests the proportion of adults reporting daily drinking
increased from 5.3 per cent in 2002 to more than nine per cent in 2009.


Tobacco smoking is down slightly, but the use of cannabis, or
marijuana, has increased from 8.7 per cent in 1996 to 13.3 per cent in
2009.

'Storm' in a Tea Cup Raises Larger Concerns

'Storm' in a Tea Cup Raises Larger Concerns | The Mark
The Torontotonians raising a "genderless" child should consider the ethics of experimenting on kids.

by Margaret Somerville (Director of the Centre for Medicine, Ethics, and Law, McGill University)

The following is the full article (highlighting is mine) as it was published in the Ottawa Citizen.

With same-sex marriage, we saw the advent of arguments for
“genderless parenting” – the idea that all a child needs is love, and
that it’s irrelevant whether the loving persons are male or female. Now
we have “genderless kids.”
Kathy Witterick and David Stocker, the parents of five-year-old Jazz,
two-year-old Kio, and three-month old Storm, want to rear and love each
of their children not as a daughter or son, not as a girl or a boy, but
just as a child.


Now, at one level, that’s not a bad thing. It’s a statement of
unconditional love for one’s child simply because he or she is one’s
child, and it stands as a small counter-statement to the abomination of
the millions of missing girls in India and China, where daughters are
aborted or killed as infants because the parents want a son instead.


But, as the Supreme Court of Canada, citing the United States Supreme
Court, once said, in distinguishing what parents were free to decide
with respect to their own medical treatment as compared with what they
could decide for their children, “Parents may be free to become martyrs
themselves. But it does not follow they are free, in identical
circumstances, to make martyrs of their children.”


So, are Witterick and Stocker making martyrs of their children? Is
their conduct with respect to their children unethical? And, if it is,
does society have any obligation to step in? These are difficult
questions to answer, and ones that require us to consider some
definitions and facts.


First, a person’s sex is a matter of biology: Women have two X
sex chromosomes, and men have one X and one Y. (There are other
combinations, such as XXY or XO, but these are not the norm, and the
people who have them are usually infertile).


Gender, on the other hand, is the cultural expression of male and female. For most people, gender parallels their biological sex.


Media reports quote Witterick and Stocker as wanting their children
to be “gender creative.” In trying to achieve this goal, they allow the
two older boys “to make their own choices” with respect to clothing and
hairstyles (they often wear pink feather boas, dresses, and braids). As a
result, the boys are often mistaken for girls, and other children do
not want to play with “that girl-boy.”


The sex of the baby, Storm, has not been disclosed to anyone other
than the midwives who delivered it, a close family friend, the father,
and the two siblings, who have been told to keep it secret (which also
raises ethical issues). They refer to the baby as “Z,” not he or she.
Even the grandparents don’t know Storm’s sex.


To analyze this situation, ethically and legally, the basic
presumption from which we start is that the parents have a right to make
decisions concerning their children, and have obligations to them in
doing so. That right can be displaced, however, when the parents’
conduct constitutes neglect or abuse. My guess is that most people would
be very reluctant to argue that that’s the case here, but, at the same
time, many believe that these children are going to have a difficult
path in life as a result of the nature of their upbringing.
So what do
we need to consider in trying to gain some insights as to whether the
parents’ present approach is acceptable?


The parents seem to believe that children “can make choices to be
whoever they want to be,” including regarding their gender, and they are
giving them the opportunity to do this. Are the parents, however,
conducting a social experiment on their children, or – as it’s been
described – “a social experiment of nurture”? If so, the principles
governing experimentation should be especially stringent when children
are the subjects, because children are classified as “vulnerable
persons.” Ethics requires that, when there is a conflict that prevents
us from honouring everyone’s rights or claims, we must decide in a way
that gives a preference to the most vulnerable people.


As with all experimentation, we can only find out later what harm may
result, but we have obligations, at the very least, to avoid reasonably
foreseeable harm. In this regard, we might learn from past unethical
experimentation. Sexologist and psychologist Dr. John Money's experiment on David Reimer
is a tragic example. In the infamous case, Reimer was sexually
reassigned after a botched circumcision destroyed his penis. Money
reported the reassignment as successful, and as evidence that gender
identity is primarily learned. However, later research showed that
Reimer never identified as female, and he began living as male at age
15. He lived a tormented life and eventually committed suicide.


I suggest that we might also gain insights from asking: “Are the
parents doing this for the kids, as they claim, or are they doing it for
themselves?” My guess is that they would say – and probably believe –
they’re doing it for the kids, but that their own ideological and
political beliefs are the main motivation. When the adults’ beliefs
about such things are concordant with the “best interests” of the
children, there is no problem – but when they clash, there is. The
conflict situation can be compared to that of a physician asking a
patient to participate in a medical experiment. Long ago, as a
protective measure, we started to teach patients to ask doctors who
approached them to be research subjects: “Are you doing this for me,
doctor, or am I doing it for you?” These kids need someone to ask their
parents that question for them.


It merits noting that there is an ethical difference between parents
having children who are non-conformist in some ways, and parents
intentionally making their children non-conformist, as in this case. As
well, parents are still making a choice when they choose not to choose for their children.


Witterick and Stocker’s strong emphasis on the idea of choice, and on
giving their children choice, even at such a young age, is also
noteworthy. In many ways, it seems naïve. It is a rejection of the
belief that there is a natural reality, including with respect to our
own selves, with which we need to live in harmony and balance. Much of
what makes us who we are as individuals, and what matters to us as human
beings, is not open to choice. The new field of epigenetics
is showing us, from one scientific perspective, just how complex the
interaction of nature and nurture is in forming who we are and who we
become.


There is also arrogance in ignoring millennia-worth of human wisdom
when it comes to what we need in order to become as fully actualized as
we can. Before the “choice armies” come after me, let me quickly add
that this does not mean that we must not change or continue to evolve
socially. Instead, it means that, in seeking to do good, we must be
careful that we do not do serious harm to individuals or society.


Finally, in the context of some other work I’m involved in from time
to time, it’s interesting to note that the most socially liberal parents
(such as Storm’s parents) and the most socially conservative ones (such
as, for example, those who want strict obedience from their children
and are willing to use corporal punishment to get it) both want the
state to keep its nose out of family issues. (Strange bedfellows!) But
society always has residual obligations to protect its children.

Tourette's may be linked to histamine levels

Treating Tourette's: Scientific American
Excerpts:
...
Tourette’s syndrome is most pronounced in children. The physical and
vocal tics, which can alienate kids from peers, are difficult to treat.
First-line drugs are limited in their efficacy, whereas more effective
antipsychotics have many potential long-term side effects, including
weight gain and movement disorders. Investigators may be moving closer
to a new treatment option involving drugs that already exist.

Last year researchers identified a new gene mutation associated with
the disorder. Known mutations have only explained a small number of
Tourette’s cases, so the investigators, led by Matthew State,
co-director of the Yale Neurogenetics Program, studied a rare family in
which the father and his eight children all had Tourette’s. In these
family members, the gene involved in the production of histamine in the
brain was shorter than normal, generating lower levels of the compound,
which is involved in inflammatory response. State believes these lower
levels can cause tics, and he is looking for this and further
histamine-related mutations in other people with Tourette’s.


Now scientists have found parallels between this family and
histamine-deficient mice, which furthers the connection to Tourette’s.
Most individuals with Tour­ette’s have low prepulse inhibition, meaning
that they are more easily startled or distracted than the average
person, says Christopher Pittenger, director of the Yale OCD Research
Clinic. In May he was to pre­sent new data to the Society of Biological
Psychiatry that both this family and mice missing the histamine gene had
low prepulse inhibition and tics. Other experiments have shown that
histamine-boosting drugs decrease ticlike behaviors in mice.


...
Drugs that increase histamine are already being tested to treat other
neurological conditions, as well as attention-deficit hyperactivity
disorder, which is often found in people with Tourette’s.

Drinkable vaccines for babies coming to Ontario

Drinkable vaccine for babies among changes saving families up to $350 - Parentcentral.ca

Ontario newborns will soon be able to receive a new, drinkable vaccine to protect them from diarrhea, vomiting and dehydration.


Nearly 140,000 infants will benefit from the oral rotavirus
vaccine, the Liberal government says. They are set to announce a number
of changes to its publicly funded immunization program this morning.


Ontario is the first jurisdiction in Canada to cover the oral rotavirus vaccine, according to Health Minister Deb Matthews.


Beginning this August, the government will offer two new vaccines —
one for rotavirus and the other a combined chicken pox and
measles-mumps-rubella vaccine known as MMRV.


The government says the vaccine change will save families up to $350 per person.


Also this August, Ontario will cover a second childhood dose of the
varicella (chicken pox) vaccine to enhance protection and they’ll pay
for a lifetime dose of the pertussis, or whooping cough vaccine.


“Immunization is one of the most effective ways to protect yourself
and your family,” said Dr. Arlene King, Ontario’s chief medical officer
of health in a release.

People with Tourettes syndrome have tremendous cognitive motor control

People with Tourettes syndrome have tremendous cognitive motor control
Excerpt:

The motor outputs of children with Tourettes syndrome are under
greater cognitive control. You might view this as their being less
likely to respond without thinking, or as being less reflexive.



This helps explain why some people may have many tics as children,
but as adults have very few. Over time, their brains have developed ways
to control these tics. Jackson points out that this may mean people
with Tourettes need mental exercises rather than brain surgery or drugs,
because their brains will naturally develop compensatory mechanisms.

LSD makes a comeback as a possible clinical treatment

LSD Returns--For Psychotherapeutics: Scientific American
Excerpt:

The preliminary study picks up where investigators left off. It
explores the possible therapeutic effects of the drug on the intense
anxiety experienced by patients with life-threatening disease, such as cancer.
A number of the hundreds of studies conducted on lysergic acid
diethylamide-25 from the 1940s into the 1970s (many of poor quality by
contemporary standards) delved into the personal insights the drug
supplied that enabled patients to reconcile themselves with their own
mortality. In recent years some researchers have studied psilocybin (the
active ingredient in “magic mushrooms”) and MDMA (Ecstasy), among
others, as possible treatments for this “existential anxiety,” but not
LSD.


Gasser, head of the Swiss Medical Society for Psycholytic Therapy,
which he joined after his own therapist-administered LSD experience, has
only recently begun to discuss his research, revealing the challenges
of studying psychedelics. The $190,000 study approved by Swiss medical
authorities, was almost entirely funded by the Multidisciplinary
Association for Psychedelic Studies, a U.S. nonprofit that sponsors
research toward the goal of making psychedelics and marijuana into
prescription drugs. Begun in 2008, the study intends to treat 12
patients (eight who will receive LSD and four a placebo). Finding
eligible candidates has been difficult—after 18 months only five
patients had been recruited, and just four had gone through the trial’s
regimen of a pair of all-day sessions. “Because LSD is not a usual
treatment, an oncologist will not recommend it to a patient,” Gasser
laments.


The patients who received the drug found the experience aided them
emotionally, and none experienced panic reactions or other untoward
events. One patient, Udo Schulz, told the German weekly Der Spiegel
that the therapy with LSD helped him overcome anxious feelings after
being diagnosed with stomach cancer, and the experience with the drug
aided his reentry into the workplace.


The trials follow a strict protocol—“all LSD treatment sessions will
begin at 11 a.m.”—and the researchers are scrupulous about avoiding
mistakes that, at times, occurred during older psychedelic trials, when
investigators would leave subjects alone during a drug session. Both
Gasser and a female co-therapist are present throughout the eight-hour
sessions that take place in quiet, darkened rooms, with emergency
medical equipment close at hand. Before receiving LSD, subjects have to
undergo psychological testing and preliminary psychotherapy sessions.


Another group is also pursuing LSD research. The British-based
Beckley Foundation is funding and collaborating on a 12-person pilot
study at the University of California, Berkeley, that is assessing how
the drug may foster creativity and what changes in neural activity go
along with altered conscious experience induced by the chemical. Whether
LSD will one day become the drug of choice for psychedelic
psychotherapy remains in question because there may be better solutions.
“We chose psilocybin over LSD because it is gentler and generally less
intense,” says Charles S. Grob, a professor of psychiatry at the
University of California, Los Angeles, who conducted a trial to test
psilocybin’s effects on anxiety in terminal cancer patients. Moreover,
“it is associated with fewer panic reactions and less chance of paranoia
and, most important, over the past half a century psilocybin has
attracted far less negative publicity and carries far less cultural
baggage than LSD.”

What makes antidepressants work

At last scientists finally understand what makes antidepressants work
Excerpt:

Most antidepressants don't show an immediate effect - instead, they
take about three weeks to kick in. For the longest time, scientists
couldn't actually explain this delay. They knew the antidepressants had
to somehow "adapt" themselves to the neural pathways, but what that
actually meant was anyone's guess. Now a team of French researchers have
figured it out: antidepressants need three weeks to shut down a
particular chemical regulator of microRNA.


This particular microRNA, designated miR-16, is in charge of making
the serotonin transporter, and is generally found in the serotonergic
neurons that produce serotonin. However, miR-16 is also found in neurons
responsible for making the neurotransmitter noradrenaline. Here, miR-16
has precisely the opposite purpose - it completely blocks the
production of serotonin in these neurons.




When drugs like Prozac go to work, they cause the serotonergic
neurons to release signals. These signals cause the miR-16 to die off,
which frees up the noradrenaline neurons to start making the serotonin
transporter as well. Thus, Prozac both directly boosts the production of
serotonin in the serotonergic neurons and indirectly causes the
noradrenaline neurons to start making it as well.

Wind Farms and Health in Canada

Komorowski’s Korner – No Adverse Health Effect from Wind Turbines – June 5, 2010 – Cornwall Ontario |
A report from Dr. Arlene King, Ontario's Chief Medical Officer of Health, states that there is not any direct causal link between wind turbine noise and adverse health effects.

An Angus Reid survey has shown that most people support renewable energy generation, including wind power. Most opposition comes from people in the locations where wind farms are to be built. I occasionally see posts about negative health effects, but they seem to be unsubstantiated claims without proof. You would think that, with all the wind farms around the world, especially in Europe and Britain, where they have had large wind farms for many years, if there were adverse health effects, then they would have come to light by now.

From what I have seen and read about the dangers of different kinds of energy production, I'll take wind power over nuclear or coal power generation any day.

Anyway, read the link at the top for more information on the health report.

Here is a list of Wind Farms in Canada.

Doctor's determine a way to reduce risks from ovarian cancer

B.C. study a ‘eureka moment’ in fight against ovarian cancer - The Globe and Mail
Excerpt:

Removing fallopian tubes as part of hysterectomies and tubal
litigations would “have an immediate impact on saving lives,” said
Dianne Miller, a gynecologic oncologist with the Ovarian Cancer Research
Program of the B.C. Cancer Agency.

That is because,
paradoxically, the most deadly form of ovarian cancer originates in the
fallopian tubes – where eggs travel from the ovaries to the womb – not
the ovaries per se, she said.
