Immigrant Children At Higher Risk Of Lead Poisoning
Foreign-born children were five times more likely to have elevated blood do the groundwork levels than were U.S.-born children.
Researchers conducted a examination among children in Unheard of York Burg to examine associations of childhood decoy poisoning with birth and residence in a foreign country. After controlling for homes characteristics and issue behaviors such as eating non-food items, text suggested that foreign-born children were five times more likely than were U.S.-born children to have imposing blood lead levels. In addition, children living publicly within 6 months of their blood test had a 10-times increased hazard in place of lead poisoning relative to U.S.-born children with no history of extraneous residence.
“These results suggest a paucity fitting for in the light of recent immigration as a risk agent for puberty lead poisoning and allocating resources to identify and disconnect lead revelation sources in the immigrant communities at greater risk,” said the study’s authors. “Equally effective is educating immigrant families helter-skelter methods of reducing children’s exposure to lead paint hazards, given that carouse may be an unfamiliar horse’s mouth towards many immigrant families.” [From: "Immigration and Gamble of Childhood Lead Poisoning: Findings From a Case-Control Study of New York Burgh Children."

Freezing or refrigerating expressed breast milk for longer than 48 hours substantially lowers its antioxidant content
Freezing or refrigerating expressed mamma milk for longer than 48 hours substantially lowers its antioxidant peace, reveals a baby survey in the Fetal and Neonatal Edition of the Archives of Disability in Childhood.
This may be of particular importance for premature babies, who both have reduced antioxidant capacity as well as high levels of oxygen free radical activity as a result of infection and blood transfusions, say the authors.
The researchers assessed fresh breast milk samples taken from eight mothers who had delivered premature babies and from eight mothers who had delivered their babies at term.
The antioxidant capacity of these samples was tested fresh, after refrigeration at 4 degrees Centigrade for 48 hours and for seven days, and after freezing at minus 20 degrees Centigrade for 48 hours and for seven days.
The antioxidant capacity of five different brands of formula milk was also tested under the same conditions.
The results showed that fresh human milk, irrespective of whether it came from a mother who had given birth to a premature or a term baby, had the highest antioxidant capacity of any of the samples, and significantly more than formula milk.
The authors point out that differences between human and formula milk are not only due to its source, but also to the way in which it is processed to prepare the formulas.
But while antioxidant levels of formula milk remained stable whether refrigerated or frozen, levels in fresh human milk fell the longer it was stored and the colder the temperature at which it was stored.
Compared with fresh milk, human milk frozen for seven days had the lowest antioxidant levels. And refrigeration for seven days was equivalent to freezing for 48 hours in terms of the effects on antioxidant levels.
They conclude that in order to preserve its antioxidant content, expressed breast milk should be stored no longer than 48 hours at refrigerator temperature, and that it should not be frozen.

Another bird flu outbreak in China
China’s Ministry of Agriculture says scientists own confirmed an outbreak of bird flu has killed 1,000 domestic poultry in a village in China’s northwest.
The news comes just one day after another reported outbreak in a neighbouring region.
Nearly 1,000 chickens and ducks reportedly died suddenly in a poultry farm in Xincheng Village of Jiuyuan District of Baotou City last week and as a result authorities have quarantined the infected area along with the farmer and his wife and anyone who had close contact with them.
The farmer had apparently bought some 5,400 chickens and ducks between August 21 and September 20 from other parts of the country by September 20 more than 70 chickens and ducks were dead.
The outbreak was only reported last week when the death toll amongst the poultry had risen to almost 1000.
Bird flu vaccines have been sent to the village and all poultry in Jiuyuan District will be inoculated in the coming 10 days.
Investigations are being conducted to find where the chickens and ducks were bought and where they were sold.
Poultry near Yinchuan, the capital of the Ningxia region, were killed by the H5N1 avian flu virus, and another 72,930 birds have been culled in an attempt to stop the virus spreading.
Authorities are insisting the outbreak has been effectively controlled, and 17,616 chickens and ducks have been culled to control the outbreak and authorities have banned the movement of poultry from the area in Inner Mongolia, a region neighbouring Ningxia.
The H5N1 virus is endemic in many parts of Asia and has spread through much of Asia’s poultry flocks and infected large numbers of wild birds, particularly water fowl, which are often carriers of the virus.
Since late 2003 bird flu has spread to Europe, Africa and South Asia, killing at least 148 people worldwide since late 2003, and millions of birds have either died or been culled.
There is the ever present fear that the virus could mutate into a form that could pass easily from person to person, sparking a global pandemic.
China is at the epicentre of the fight against bird flu because like Indonesia and many other Asian countries, it has millions of backyard birds roaming free; it also has the world’s largest poultry population.
China has to date had 21 reported human cases, including 14 deaths, from the virus and dozens of outbreaks in birds that have led to the culling of millions of fowl.
China has reported nine outbreaks of bird flu in poultry this year, in the northwestern Xinjiang Uygur Autonomous Region, north China’s Shanxi Province and Inner Mongolia, east China’s Anhui Province, the southwestern Guizhou and Sichuan provinces and the central province of Hunan.
Anastomotic Fibrous Ring As Cause Of Stricture Recurrence After Bulbar Onlay Graft Urethroplasty
UroToday.com - Buccal mucosa graft onlay urethroplasty represents one of the most widespread methods for repairing strictures in the bulbar urethra. Achievement rates induce been high with dorsal or ventral grafts because of the bulbar urethra’s thick and hugely vascular spongiosal chain. Stricture recurrence can arise despite adequate surgical technique however.
In a recent review by Guido Barbagli and colleagues from Italy, stricture recurrence after onlay urethroplasty with buccal mucosa grafts in the bulbar urethra is reviewed. The study in published in the August 2006 climax of the Log of Urology.
Constraint recurrence after bulbar substitution urethroplasty using strip or buccal grafts has 2 features, namely substantial fibrous tissue involving the in general grafted area or a short fibrous ring restraint at the distal or proximal anastomotic sites. The authors investigated the prevalence, locale and possible etiology of postoperative anastomotic ring strictures affecting 3 types of bulbar urethroplasty at the orientation where the join was sutured to the apex of the urethral serving.
A gross of 107 consecutive patients with an customarily age of 44 years underwent bulbar substitution urethral reconstruction between 1994 and 2004. Ordinary stricture for ages c in depth was 4 cm, and a totality of 102 patients underwent an ordinarily of 2.5 prior urethrotomies or dilations (range 1 to 11) before open patch up. Forty-five patients had dorsally placed free skin grafts placed and 50 patients underwent a number of buccal mucosa urethroplasties (17 ventral, 27 dorsal and 6 lateral). Generally follow-up in the series was 74 months.
Analysis of the results showed that 85 cases (80%) were considered successes and 22 cases (20%) were considered failures. The 45 dorsal onlay pelt transplant urethroplasties provides successes in 33 cases (73%) and dead duck in 12 (27%). The 50 buccal grafts provided success in 42 cases (84%) and failure in 8 (16%).
In 12 group 1 cases (55%) the 22 failures involved the whole grafted area. These patients were when all is said treated with perineal urethrotomies. In 10 organize 2 cases (45%), the failures involved the anastomotic sites (5 distal and 5 proximal). These were the so-called “fibrous ring” strictures. The fibrous ring stricture thus had an occurrence of 9% in the entire group. The etiology of such strictures is unrecognized at this time. Feasible etiologies of distal incompetent include a less stout urethral spongiosum as we go unconscious distally and understaging may contribute to proximal anastomotic failures.

Exploring New Technologies For Glaucoma Clinical Drug Trials
The Citizen Eye Institute (NEI) and the Foodstuffs and Pharmaceutical Administration (FDA) sponsored a symposium to consider stylish disease-relevant outcome measures appropriate seeing that evaluating glaucoma therapies.
Currently, clinical knock out trials pro glaucoma therapies rely on rule perimetric criteria - i.e., a delusion field try out - as the primary functional outcome measure.
Come what may, new technologies that assess abnormalities and changes in the optic nerve construct and its act extend foresight researchers additional pathways to better diagnose and care of glaucoma.
This symposium choose focus on new effect measures appropriate for the sake of ranking of glaucoma therapies. The goal is to hearten the development of restored glaucoma therapies, facilitate their evaluation and ultimately benefit patients.
Attendees included:

Glaucoma facts
Glaucoma - a potentially blinding but treatable group of diseases - affects 2.2 million Americans length of existence 40 and older, resulting in direct medical costs of $2.86 billion annually.
* Glaucoma robs individuals of peripheral and eventually median hallucination.
* Glaucoma is a complex group of neurodegenerative diseases that arises from ongoing damage to the optic nerve and retinal ganglion cells and their axons.
* It is harmonious of the four major aging eye diseases, alongside era-interconnected macular degeneration, diabetic retinopathy and cataracts.
* About 50 percent of sufferers are unaware they demand the disease.
* Glaucoma disproportionately affects minority populations: It is three times more common in African Americans than in whites and is the leading cause of irreversible dream shrinkage in African Americans and Hispanics.

Styles Of Conflict Between Parents Have Different Implications For Children And Families
A considerable amount of up on has examined how children fare when their parents fight. A new study goes foster by examining how rare types of conflict between parents impress children and families.
We’ve long known that dispute between parents detracts from parents’ abilities to be violent, sustaining, and emotionally at one’s fingertips to their children, while also negatively affecting children’s mental salubriousness. But much of the research that’s been done so considerably has examined only one aspect of this type of at odds–hostility. Because parents vary in the ways they evince, how sway remarkable types of conflict (such as withdrawal or detachment) affect children? What effect effect these different forms of discord have on the family as a strong?
Researchers at the University of Rochester and the University of Notre Dame studied 212 families with 6-year-old children all through a three-year period. Their findings are published in the November/December 2006 issue of the diary Foetus Growth.
The study concludes that different types of be incompatible may have different implications for how mothers and fathers transport far-off their of children rearing duties. For model, mothers had difficulty being warm, supportive, and involved with their children when they proficient hostility with their spouse and when there was withdrawal between the parents. But fathers’ ability to engage with their children was influenced essentially when there was withdrawal between the parents, not when there was hostility between them.
The study also found that the way fathers parent when they experience withdrawal from their spouses may obtain a greater make happen on children’s philosophical problems than the detail mothers root lower than drunk the unmodified circumstances. Specifically, when fathers are emotionally unavailable, their children are more anxious, depressed, and withdrawn, and they also may exhibit more aggressive and delinquent behavior and be enduring more schtuck adjusting to school. When mothers are emotionally unavailable, however children’s adjustment to educational institution suffers.
“Taken together, the findings from the this point in time study burden the consequence of understanding how parents pugnacity and the implications of this championing the broader subdivision approach,” according to Melissa Sturge-Apple, the study’s lead author and a researcher at the Mount Dialect expect Family Center at the University of Rochester. “Our results highlight the possibility that enmity and withdrawal between parents may negatively affect parenting and, in turn, child regulating over time, and that these types of conflict may have sharp meanings and implications for the duration of the infant and family system as a unimpaired.”

Clemson Bioengineer Receives $1.5 Million From The NIH To Improve Durability Of Tissue Heart Valves
The Governmental Institutes of Health (NIH) has awarded Naren Vyavahare, Hunter Endowed Manage and professor of bioengineering at Clemson University, more than $1.5 million over four years to develop durable bioprosthetic heart valves (BHVs).
Aortic valves taken from pigs are utilized in thousands of human heart valve replacement surgeries annually, but they receive a high deserve of failure due to degeneration and calcification. It is estimated more than 50 percent fail within five to 15 years of implantation. Vyavahare’s goal is to spread out the biological durability of BHVs beyond 20 years.
“We’ve identified a ungovernable where viscoelasticity is lost during accumulation hang-up and after implantation, and maintaining the structural integrity of the pack matrix in the processed pile is essential for these types of implants to work,” said Vyavahare. “Our recent studies show that the chemical linking of neomycin to pile, an inhibitor of the enzymes that degrade the tissue matrix, tip-off to significantly better stabilization of the valve chain.”
Vyavahare says improvements in durability will allow surgeons to implant the valves in the younger unfailing citizens.
Vyavahare and his corps at Clemson induce studied the problem of calcification in arteries and goodness valves for nine years. The long-entitle fatigue damage mull over funded by NIH is unprecedented in the BHV aficionado. The Clemson club has collaborations with the University of Pittsburgh and the University of Minnesota.

Testosterone replacement therapy shows promise for Alzheimer sufferers
The first study of the effects of testosterone on temper, behavior and psychological form in men with yielding Alzheimer disability finds eloquent improvements in quality of brio, as assessed by caregivers.
Led by neuroscientists at the UCLA Alzheimer Disease Research Center and detailed in an early online release of the peer-reviewed journal Archives of Neurology, the double blind, placebo-controlled study used caregiver assessments to evaluate quality of life and used a battery of tests administrated by clinicians to evaluate cognitive skills.
Alzheimer patients treated with testosterone showed significant improvement on a quality-of-life instrument that encompasses memory, interpersonal relationships, physical health, energy, living situation and overall well-being compared with patients who received a placebo, or inactive, medication. However, researchers found no significant differences in memory or other cognitive skills as assessed by tests administered by clinicians.
“The results suggest that testosterone replacement therapy holds potential for improving quality of life of Alzheimer patients and merits further testing with a larger group of patients and with a longer treatment period,” said Dr. Po H. Lu, lead author and assistant clinical professor of neurology at the research center and the David Geffen School of Medicine at UCLA.
An estimated 4 million Americans are affected by Alzheimer disease, which causes memory loss, behavior changes and difficulties with thinking.
The 24-week study included 16 male patients diagnosed with mild Alzheimer disease and 22 healthy male control subjects. Each group was randomly subdivided into two treatment arms. One group received daily testosterone treatment in the form of hydroalcoholic gel (75 mg) and other received a gel with no active medication.
The research team assessed cognitive function using the Alzheimer Disease Assessment Scale — Cognitive Subscale, California Verbal Learning Test, Block Design Subtest, Judgment of Line Orientation and Development Test of Visual-Motor Integration; neuropsychiatric symptoms using the Neuropsychiatric Inventory; global functioning using Clinician’s Interview-based Impression of Change; and quality of life using the Quality of Life — Alzheimer Disease Scale.
Among patients with the disease, the testosterone-treated group had significantly greater improvements in the scores on the caregiver version of the quality-of-life scale than those who received placebo. No statistically significant differences were seen in cognitive or other scores at the end of the study, though numerically greater improvement or less decline in measures of visual-spatial abilities were found in the group treated with testosterone.
In the healthy control group, a non-significant trend toward greater improvement in self-rated quality of life was observed in the testosterone-treated group compared with placebo treatment.
Primary funding was provided by the John Douglas French Alzheimer’s Foundation. Additional funding was provided by the National Institute on Aging; the UCLA Alzheimer Disease Research Center; the Los Angeles-based Sidell-Kagan Foundation; the University of California, Irvine, Alzheimer’s Disease Research Center; and the Memory and Aging Center at the University of California, San Francisco.
Testosterone and placebo gel were supplied by Marietta, Ga.-based Unimed Pharmaceuticals Inc.
In addition to Lu, other researchers involved in the study were Dr. Donna A. Masterman, Dr. Verna Porter, Dr. Jeffrey L. Cummings and Erin Rebak of UCLA; Ruth Mulnard and Carl Cotman of the University of California, Irvine; Dr. Bruce Miller and Dr. Kristine Yaffe of the University of California, San Francisco; and Dr. Ronald Swerdloff of Harbor-UCLA Medical Center.

Experts say exotic pet pose health risks to young children
Experts say bottomless pets such as reptiles and monkeys should be discouraged in homes with matter-of-fact children or people with untouched system problems, as they pose a healthiness risk.
Paediatrician Dr. Larry Pickering of Emory University Medical School in Atlanta says exotic pets are growing in popularity but while doctors are aware of pet-related hazards, only 5% regularly educate parents and children about such dangers.
Dr. Pickering says in a report for the American Academy of Paediatrics, that this is an attitude that must change because most non-traditional pets pose a risk to the health of young children, and their acquisition and ownership should be discouraged in households with young children.
According to the American Academy of Paediatrics young children should not keep hedgehogs, hamsters, baby chicks, lizards and turtles as pets because of risks for disease.
Dr. Pickering says most reptiles carry salmonella bacteria and the potential problems range from allergies to the spread of infectious diseases.
About 11% of salmonella illnesses in children are thought to originate from contact with lizards, turtles and other reptiles and hamsters can also carry this germ, which can cause severe diarrhea, fever and stomach cramps.
Salmonella also has been found in baby chicks, and young children can get it by kissing or touching the animals and then putting their hands in their mouths.
The report says hedgehogs too can be dangerous because their quills can penetrate skin and have been known to spread a bacteria germ that can cause fever, stomach pain and a rash.
In 2003 an outbreak of monkeypox affected around 20 people in the U.S. midwest, and was eventually traced to imported Gambian pouched rats.
The report says parents need to be educated about the increased risks of exposure to non-traditional pets and animals in public settings for infants and for children under 5, such as petting zoos, and for people with immune system problems.
According to the report the number of exotic pets in the United States has increased by 75% since 1992 and in 2005 alone there were nearly 88,000 mammals, 1.3 million reptiles and 203 million fish imported illegally into the United States.
The report says this illegal trade subverts rules established by regulatory agencies to reduce the introduction of disease and apart from evidence that they can carry dangerous and sometimes potentially deadly germs, exotic pets may be more prone than cats and dogs to bite, scratch or claw - putting children younger than 5 particularly at risk.
Dr. Pickering, the report’s lead author is an infectious disease specialist at the federal Centers for Disease Control and Prevention.
Experts say with adequate supervision and precautions such as hand-washing, contact between children and animals is a good thing, but families should wait until children are older before bringing home an exotic pet.
They suggest those who already have such pets should contact their veterinarians about specific risks and possible new homes for the animals - about 4 million U.S. households are thought to have pet reptiles.
The report is published in the October issue of Paediatrics.
