Tips on<br />
dementia<br />
DEMENTIA IS a broad category<br />
of brain diseases that cause<br />
a long term and often gradual<br />
decrease in the ability to think<br />
and remember that is great<br />
enough to affect a person's daily<br />
functioning. Other common<br />
symptoms include emotional<br />
problems, problems with language,<br />
and a decrease in motivation<br />
• Dementia is mainly a disease<br />
of old age.<br />
• About 47m people around<br />
the world are living with dementia.<br />
• It is expected to rise to<br />
115m by 2050.<br />
• One in three dementia cases<br />
can be prevented<br />
• People with dementia may<br />
have problems with short-term<br />
memory, keeping track of a<br />
purse or wallet, paying bills, planning<br />
and preparing meals, remembering<br />
appointments or<br />
traveling out of the neighborhood.<br />

Cow antibodies for AIDS cure soon<br />
IN A significant find, a team<br />
of researchers has reported<br />
for the first time elicitation<br />
of powerful, HIV-blocking<br />
antibodies in cows in a matter<br />
of weeks -- a process<br />
that usually takes years in humans<br />
-- paving the way for developing a<br />
broadly effective AIDS vaccine in<br />
the near future.<br />
According to the study, published<br />
in the prestigious journal<br />
Nature, the unexpected discovery<br />
in cows is providing clues for important<br />
questions at a moment<br />
when new energy has infused HIV<br />
vaccine research.<br />
"One approach to a preventive<br />
HIV vaccine involves trying to<br />
elicit broadly neutralising antibodies<br />
in healthy people, but so far<br />
the experiments have been unsuccessful,<br />
in both human and animal<br />
studies," said lead author Devin<br />
Sok, Director, Antibody Discovery<br />
and Development at the International<br />
AIDS Vaccine Initiative<br />
(IAVI).<br />
"This experiment demonstrates<br />
that not only is it possible to produce<br />
these antibodies in animals,<br />
but we can do so reliably, quickly,<br />
and using a relatively simple immunisation<br />
strategy when given in<br />
the right setting," Sok added.<br />
Scientists have known that<br />
some people living with chronic<br />
HIV infection produce broadly<br />
neutralising antibodies (bnAbs),<br />
which can overcome the high levels<br />
of diversity of HIV.<br />
One type of bnAb uses long,<br />
arm-like loops that are capable of<br />
reaching concealed areas on the<br />
virus's surface to block infection.<br />
The scientists had a question:<br />
what would happen if they immunise<br />
cows with an HIV immunogen?<br />
"The answer began with a single<br />
protein on HIV's surface that<br />
serves as a bnAb target -- develop<br />
an antibody that recognises variants<br />
of this protein on different<br />
HIV viruses and<br />
you'll likely be protected<br />
from all of them," the<br />
study said.<br />
One of the many tricks<br />
that HIV uses to prevent<br />
humans from developing<br />
the right antibodies is to<br />
display irrelevant forms of<br />
this protein to distract the<br />
immune system.<br />
Scientists thought they<br />
had overcome this challenge<br />
by developing an immunogen<br />
called "BG505<br />
SOSIP", which closely<br />
mimics the protein target.<br />
In the new study, four<br />
cows immunised with<br />
"BG505 SOSIP" elicited<br />
"bnAbs" to HIV within 35-<br />
52 days.<br />
In comparison, it takes HIVpositive<br />
humans multiple years to<br />
develop comparable responses,<br />
and only 5-15% even develops<br />
them at all.<br />
"Cows cannot be infected with<br />
HIV, of course. But these findings<br />
illuminate a new goal for HIV vaccine<br />
researchers: by increasing the<br />
number of human antibodies with<br />
long loops, we might have an easier<br />
chance of eliciting protective<br />
bnAbs by vaccination," the researchers<br />
noted.<br />
There is no doubt that cows'<br />
ability to produce bNAbs against a<br />
complicated pathogen like HIV in<br />
a matter of weeks, highlights even<br />
broader significance, particularly<br />
for emerging pathogens.<br />

Red Cross Society trains 2,000 teachers in First Aid<br />
A THREE-DAY First Aid training<br />
workshop for basic school teachers<br />
in the Sekondi/Takoradi Metropolis<br />
has been held in Sekondi.<br />
The training is to equip them<br />
as active volunteers of the Ghana<br />
Red Cross Society to acquire<br />
knowledge in relief services and<br />
attend to emergency health situations<br />
in their schools and the communities.<br />
It was organised by the GRCS,<br />
in conjunction with the Ghana<br />
Education Service (GES) and attended<br />
by 72 teachers.<br />
The Western Regional Manager<br />
of the GRCS, Mr Matthew<br />
Boateng told the media on the<br />
sidelines of the training that 2,000<br />
teachers from 14 districts in the<br />
region had so far benefited from<br />
the training programme.<br />
Mr Boateng said as part of the<br />
training, the GRCS had supplied<br />
the teachers with First Aid Manuals<br />
to boost their capacity on how<br />
to deal with emergency health issues.<br />
He said every school and day<br />
care centre must have access to<br />
First Aid Kits to attend to school<br />
children in case of any casualties.<br />
Mr Boateng said most of the<br />
trained teachers had formed Disaster<br />
Management Teams<br />
through the Red Cross Society to<br />
prevent and mitigate disasters in<br />
their schools and communities.<br />
He said it was incumbent<br />
on first<br />
aiders "to adopt a<br />
life-saving technique<br />
to monitor the Airway,<br />
Breathing and<br />
Circulation (ABC) of<br />
an injured or sick<br />
person before a professional<br />
medical<br />
assistance.”<br />
He reminded the teachers<br />
that; "A good first aider to attend<br />
to ill people, disaster and<br />
accident victims, must be observant,<br />
resourceful, gentle,<br />
tactful, sympathetic, cheerful<br />
and courageous in a bid to<br />
bring relief to the situation".<br />
He said it was incumbent<br />
on first aiders "to adopt a lifesaving<br />
technique to monitor<br />
the Airway, Breathing and Circulation<br />
(ABC) of an injured<br />
or sick person before a professional<br />
medical assistance.”<br />
Mr Philip Bruce Arhin, the<br />
Regional First Aid Instructor,<br />
who took the teachers through<br />
First Aid steps, reminded them<br />
that as first aiders, they ought to<br />
make it their prime motive to<br />
“preserve lives, prevent a condition<br />
from getting worse, and promote<br />
recovery and human<br />
dignity".<br />
He appealed to the volunteers<br />
not to "frighten victims in emergency<br />
situations but encourage<br />
them that their condition will be<br />
better”.<br />
The trainees were taken<br />
through some basic steps such as<br />
cardio pulmonary resuscitation,<br />
external bleeding, wounds and<br />
cuts, bleeding with embedded object,<br />
shock, choking, drowning,<br />
burns, scalds and<br />
poisoning. GNA
