What is to be blamed for childhood cancer?

A team of researchers has thrown light on the community beliefs about what causes cancer in children, an area which remains understudied, finds a latest research.

“Few childhood cancers are attributed to genetics or environmental factors, so when children are diagnosed with cancer, families often wonder ‘why me/why us’?” said lead author Janine Vetsch, postdoctoral research candidate from UNSW Sydney in Australia.

For the study, the team examined the beliefs of more than 600 participants — parents and childhood cancer survivors — about the causes of childhood cancer, and compared them with beliefs of 510 members of the general population.

Findings, published in Acta Oncologica, revealed that more than seven out of 10 childhood cancer survivors and survivors’ parents believed that chance or bad luck caused the cancer.

This led to most parents and survivors seem to understand that there is nothing they could have done to prevent the cancer, according to Vetsch.

However, around one in five families did believe that environmental factors and genetics played a role, despite only limited available scientific evidence, results further showed.

“It looks like healthcare professionals are successfully helping most families arrive at that view,” said Vetsch.

Such views could lead to stigma. Hence, it is important to increase community knowledge of childhood cancer causes in general.

There is a need to encourage doctors to talk about the causes with affected families to address unhelpful misconceptions,” Vetsch suggested.

Birth control pills could impair women’s ability to recognise emotion

London, Feb 12: Despite the widespread use of oral contraceptives (OCPs) by women, many are not aware that it may impair their ability to recognise others’ emotional expressions, which may have serious consequences in interpersonal contexts, suggests a new study.

The study showed that healthy women who use birth control pills are poorer judges of subtle facial expressions than non-users.

“More than 100 million women worldwide use oral contraceptives, but remarkably little is known about their effects on emotion, cognition and behaviour,” said senior author Alexander Lischke from the University of Greifswald in Germany.

“However, coincidental findings suggest that oral contraceptives impair the ability to recognise emotional expressions of others which could affect the way users initiate and maintain intimate relationships,” said Lischke.

To investigate the effects of OCPs on women’s emotion recognition, the researchers administered a special emotion recognition task to two similar groups of healthy women: 42 OCP users and 53 non-users.

The findings, published in Frontiers in Neuroscience, showed that OCP users were nearly 10 per cent less accurate on average than non-users in deciphering the most enigmatic emotional expressions.

Though the groups were equally good at recognising easy expressions, the OCP users were less likely to correctly identify difficult expressions, results showed.

The effect held for both positive and negative expressions, and regardless of the type of OCP or the menstrual cycle phase of non-users.

“Cyclic variations of estrogen and progesterone levels are known to affect women’s emotion recognition and influence activity and connections in associated brain regions. Since oral contraceptives work by suppressing estrogen and progesterone levels, it makes sense that oral contraceptives also affect women’s emotion recognition,” said Lischke.

There is a need for further studies that replicate and extend the findings of the present study before thinking about changing current guidelines regarding the prescription of OCPs, the study noted.

The Delhi High Court seeks Delhi government response over bike ambulance controversy

Published

on

New Delhi, Feb 11 (IANS) The Delhi High Court on Monday asked the state government to file response to a plea alleging that trained paramedics are not deployed in bike ambulance service.

On February 7, the Central Accident and Trauma Services (CATS), an entity of the state government, launched a scheme of First Responder Vehicle, popularly known as bike ambulance service, to provide timely health assistance in traffic-congested areas and small lanes.

A bench of Chief Justice Rajendra Menon and Justice V. Kameswar Rao asked the Delhi government and CATS to file response on the plea seeking direction to deploy trained, young and energetic paramedics with requisite qualification and valid licence to drive two-wheelers.

The court has listed the matter for further hearing on May 2.

The court was hearing a plea filed by advocate Satakashi Verma and Kamlesh Kumar. In the plea, the advocates said that the scheme has been launched without doing due diligence with the help of untrained manpower, who are unfit to manage existing ambulance system due to lack of technical qualification.

The scheme was launched without deploying adequately qualified and trained paramedics, they added.

In their petition, they claimed that the existing staff of Assistant Ambulance Officer was found to be unfit for operation and maintenance of the bike ambulance service.

Researchers identify gene to treat alcoholism

Alcoholism alcohol

New York, Feb 9: Researchers have identified a gene that could provide a new target for developing medication to prevent and treat alcoholism, according to a new study on mice.

Researchers at Oregon National Primate Research Center (ONPRC) in the US discovered a gene that had lower expression in the brains of non-human primates which voluntarily consumed heavy amounts of alcohol compared to those that drank less.

Furthermore, the team unraveled a link between alcohol and how it modulates the levels of activity of this particular gene.

Researchers discovered that when they increased the levels of the gene encoded protein in mice, they reduced alcohol consumption by almost 50 per cent without affecting the total amount of fluid consumed or their overall well-being.

The study modified the levels of the protein encoded by a single gene known as GPR39.

The prevalence rates of co-occurring mood and alcohol use disorders are high, with individuals with alcohol use disorder being 3.7 times more likely to have major depression than those who do not abuse alcohol.

Using a commercially available substance that mimics the activity of the GPR39 protein, the researchers found that targeting this gene dramatically reduced alcohol consumption in mice, showed the findings of the study published in the journal, Neuropsychopharmacology.

“The study highlights the importance of using cross-species approaches to identify and test relevant drugs for the treatment of alcohol use disorder,” noted senior author Rita Cervera-Juanes, Research Assistant Professor at ONPRC.
