Gang Membership Tied To Mental Health Problems

Young men who are members of street gangs are more likely to have psychiatric illnesses and access mental health services, according to new research from the UK published online in the July 12th issue of the American Journal of Psychiatry.

Lead author Professor Jeremy Coid, Director of the Forensic Psychiatry Research Unit at Queen Mary, University of London, says in a statement this is the first time researchers have investigated a possible link between gang violence and psychiatric illness, apart from substance misuse and the burden it places on mental health services.

"Here we have shown unprecedented levels among this group, identifying a complex public health problem at the intersection of violence, substance misuse, and mental health problems among young men," says Coid.

Inner-city areas tend to have higher levels of crime and social problems.

The researchers say that in Britain, about 1% of men aged 18 to 34 are gang members, and this figure rises to 8.6% in the London Borough of Hackney, where 20% of black men reported being in a gang.

For their study, they surveyed 4,664 men aged 18 to 34 living in Britain. They note that they deliberately oversampled men from areas with high levels of violence and gang activity, that were more deprived and with a higher-than-average proportion of ethnic minority residents.

The survey was based on standard screening methods and asked the men about gang membership, violence, use of mental health services, and psychiatric diagnoses.

It found that 70.4% of the men (3,284 individuals) reported they had not been violent in the last five years, 27.3% (1,272) said they had been in a fight or assaulted someone, and 2.1% (108) reported being a current gang member.

The researchers then put the men into three groups: gang member, violent, and non-violent, and analyzed the rest of the survey results according to these groups.

These showed that violent men and gang members tended to be younger than non-violent men. They were also more likely to be born in the UK and less likely to have a job.

Violent men and gang members were also significantly more likely to report having a psychiatric illness and to be using mental health services than non-violent men.

There was, however, one exception: depression. This illness was less common among violent men and gang members than non-violent men. The researchers say:

"Violent ruminative thinking, violent victimization, and fear of further victimization accounted for the high levels of psychosis and anxiety disorders in gang members, and with service use in gang members and other violent men."

Psychosis is a term used to describe a range of mental health problems that cause loss of contact with reality, such as hallucinations and delusions (or "having a psychotic episode").

The survey results showed that of the 108 gang members, over half were drug dependent, two-thirds were alcohol dependent and over 85% had an antisocial personality disorder.

They also found that over half of the gang members had an anxiety disorder and one in three had attempted suicide.

The researchers propose that post-traumatic stress disorder (PTSD), the most common psychiatric condition to result from exposure to violence, may account for the high levels of anxiety disorder and, at least partly, for the high levels of psychosis among gang members.

As street gangs are on the increase in UK cities, the researchers suggest young men in areas where gang activity is high who seek mental health services should be routinely assessed for gang membership.

The elevated levels of attempted suicide among gang members could be linked to psychiatric illness, say the authors, but they also suggest it could be linked to the idea that impulsive violence can be directed at oneself as well as others.

Coid says the survey may have missed some important features of gang membership because they limited the sample to men between the age of 18 and 34, and the average age of a gang member is around 15:

"So gang members in this study should be considered 'core' gang members who have not stopped in early adulthood."

He says more studies following young men should now be done to confirm if their findings are specific to this group.

The research was funded by the The National Institute for Health Research (NIHR) and the Maurice and Jacqueline Bennett Charitable Trust.

In a federally funded study that explored the benefits of gang membership in the US, researchers discovered that children who join gangs feel safer despite a greater risk of being assaulted or killed.

Is Cat Poop A Danger For Public Health?

Every year, 1.2 metric tons of cat feces are deposited in the US, raising the risk of infection with the Toxoplasma gondii parasite, researchers from the Stanley Medical Research Institute and Johns Hopkins University Medical Center reported in Trends in Parasitology (July 10th, 2013 issue).

Some cat feces are contaminated with Toxoplasma gondii, a protozoan known to cause toxoplasmosis epidemics in healthy individuals, not just patients with weakened immune systems and pregnant mothers.

Co-author, E. Fuller Torrey, said: "The accumulation of Toxoplasma gondii oocysts, found in cat feces, may be a much bigger problem than we realize because of their apparent long life and their association with some diseases."

Torrey said authorities need to gain better control of cat populations, especially feral cats. He also called for more research.

American backyards and communities contain between 3 and 400 oocysts per square feet. Just one single Toxoplasma gondii oocyst can infect a human.

There are between 25 and 60 million
feral cats in the USA

Cats become infected when they catch infected mice, birds and other small mammals. The infected cat then spreads oocysts through its feces in soil, water, grass, etc.

If you have a pet cat, no mice or rats in your home and your pet stays indoors all the time, you have nothing to worry about, Torrey said. If it does spend time outdoors, be extremely careful with litter boxes, makes sure sandboxes are covered, and wear gloves when you are gardening.

Torrey quoted one study showing that 100 T. gondii oocysts may be found under your fingernails.

Co-author Robert Yolken says parents, teachers and guardians need to be extra careful with young children.

Should we get tested? - Torrey says: "No, except perhaps in the case of pregnant women. Fifteen percent of us have antibodies, including me." Somebody may test positive one day and negative the next.

Toxoplasmosis prevention in newborns inadequate in USA - American babies born with toxoplasmosis have significantly higher rates of eye and brain damage compared to infants in Europe, researchers from Stanford University School of Medicine reported in Pediatric Infectious Disease Journal.

Toxoplasmosis is a disease caused by the common Toxoplasma gondii parasite.

Signs and symptoms of toxoplasmosis are usually "flu-like" and may include

The majority of infected people will have no signs or symptoms at all.

For people with weakened immune systems, such as patients with cancer, AIDS, or transplant organ recipients on immunosuppressive medications, signs and symptoms may include the same as those listed above, plus:

ConfusionCoordination problemsSeizures (fits)Tuberculosis-like complicationsOcular toxoplasmosis - severe inflammation of the retina

If a pregnant woman becomes infected with Toxoplasma gondii, there is a 30% chance that the developing fetus will also become infected (congenital toxoplasmosis), even if the mother has no symptoms.

The pregnant mother is more likely to pass on the infection during the third trimester. However, the risk of more serious outcomes is greater earlier on during the pregnancy.

The following risks and complications are possible if the pregnant mother becomes infected with Toxoplasma gondii:

Miscarriage or stillbirthThe baby may suffer from seizuresThe newborn will have jaundiceThe infant may have serious eye infectionsThe newborn may have brain damageThe baby's liver and spleen may be enlargedMost complications appear when the child is a teenager or later, and may include:

- deafness
- recurrent and serious eye infections
- rheumatoid arthritis
- brain cancer
- mental problems, including schizophrenia, obsessive-compulsive disorder, and problems in school

As background information, Torry and Yolken informed that between 1989 and 2006 in the US, cat ownership rose by about 50%, from 54.6 million to 81.7 million. However, during the same period, the country's human population grew by only 23%. There are also between 25 and 60 million feral cats in the US.

In the UK, cat ownership rose from 4.5 million in 1990 to 8 million in 2009. Cat ownership has increased all over the world, especially in China and Latin America.

Some cat owners are very close to their pets. Torrey quoted one study showing that 62% of cats sleep with their adult owners and another 13% slept with children.

New Cry Analyzer Could Detect Babies' Health Problems

New Cry Analyzer Could Detect Babies' Health Problems
3 starsnot yet rated

Parents may sometimes wish they could interpret their babies' cries, and now researchers may have found a way to do this.

A team from Brown University and the Women & Infants Hospital of Rhode Island developed a device that analyzes a baby's cry as a means to interpret possible health or developmental problems.

The computer-based instrument may allow researchers and doctors to make use of cries as a way to determine whether a child has neurological or developmental problems.

The Journal of Speech, Language and Hearing Research recently published a paper describing the device and its testing methods.

According to a release from Brown University, the analyzer works in two steps:

It separates recorded cries from babies into frames of 12.5 milliseconds. Each of these frames is then studied for things like frequency traits, voicing and volume.The frames then go back together, and this time they are categorized as either an utterance or a silence (the pause between each utterance). The utterances are then grouped according to their length and analyzed for variables such as pitch. In addition, the lengths of the silences are measured.

In total, 80 different metrics are used to find clues about the health of a baby.

Stephen Sheinkopf, an assistant professor at Brown who helped develop the device, says:

"There are lots of conditions that might manifest in differences in cry acoustics. For instance, babies with birth trauma or brain injury as a result of complications in pregnancy, or birth of babies who are extremely premature can have ongoing medical effects.

Cry analysis can be a noninvasive way to get a measurement of these disruptions in the neurobiological and neurobehavioral systems in very young babies."

Barry Lester, director of Brown's Center for the Study of Children at Risk, has been working with Sheinkopf and others on this project as an expert in baby cries. He notes that this kind of research dates back to the 1960s, with a disorder known as Cri du chat - cry of the cat - syndrome.

Like Down syndrome, Cri du chat is a result of a genetic anomaly and is characterized by a recognizably high-pitched cry. Although the cries are perceivable by the human ear, Lester says the cries associated with that syndrome led him to wonder if there were other, smaller differences in a baby's cry that could be indicative of health.

He refers to a baby's cry as "a window into the brain."

Since the tests outlined in the team's paper show an accuracy rating of 88% to 95% for detecting voicing characteristics in the samples, the team is optimistic that their new device will be able to accurately identify problems in babies from a very early stage.

Lester adds: "Early detection of developmental disorders is critical. It can lead to insights into the causes of these disorders and interventions to prevent or reduce the severity of impairment."

In addition to aiding doctors, the team believes their device can further the research being done on "infant cry development."

Recently, a Smart Diaper was created that can communicate urine data to parents' phones, in yet another way scientists are attempting to glean health information from babies.
