Illinois Counties Facing Increases In STDs Among Teenagers; Bill Aims To Reduce Rates
Illinois health officials contend that images seen in the media, social influences, and a lack of "frank" discussion on STDs in schools, among other issues, might be contributing to increases in STD rates across the state, the State Journal-Register reports. "According to recently released data, new cases of chlamydia in Illinois reached an all-time high statewide in 2008 - 59,169 - while the number of gonorrhea cases outside Chicago has been rising in recent years and totaled 10,165 in 2008," the Journal-Register reports. In addition, about 35,000 state residents have HIV/AIDS, the article states. Charlie Rabins, chief of the STD program at the Illinois Department of Public Health, said a bill (SB 212) currently awaiting Gov. Pat Quinn"s (D) approval might help reduce STD rates. The bill "would allow what is called "expedited partner therapy," in which medical professionals who treat patients for gonorrhea or chlamydia can give those patients single-dose antibiotics to pass on to sexual partners without first examining the partners," according to the Journal-Register (Olsen, 7/27).

Lifestyle Program For Patients With COPD Is Health And Cost Effective
Patients with moderate COPD were randomized to receive "usual care" or to undergo an interdisciplinary, community-based program (INTERCOM) that offered an intensive lifestyle moderation phase of four months, during which patients were instructed in detail to perform two 15-minute intervals of pleasurable walking or cycling, and offered instruction in other lifestyle changes such as nutrition and smoking cessation. After the four-month introductory period, there was a less intensive 20-month maintenance during which patients were offered guidance but not intensive intervention.

Statistics Show Drop In Births, Lower Demand For Infertility Services During Recession
More people in the Atlanta area and across the U.S. are delaying pregnancy in a possible reaction to the current economic recession, leading to a decline in the number of couples seeking infertility treatments, the Atlanta Journal-Constitution reports. According to the Journal-Constitution, 13 states saw a decrease in the number of recorded births in 2008 compared with 2007. The Georgia Hospital Association reports that there were 5,352 fewer recorded births in Georgia in 2008 than in 2007. Mark Perloe of Georgia Reproductive Specialists said there has been a 20% decline in the number of people seeking infertility services. To retain business during the economic downturn, Perloe said Georgia Reproductive Specialists is offering a discount on select services of as much as 70%.Elisabeth Burgess, a Georgia State University sociology professor who focuses on families, said, "In times of economic downturns, different people react in different ways." For some people, "[f]amily becomes more important, so you might decide to have a child." The Journal-Constitution reports that one cycle of treatment can cost $15,000 or more, which some people pay for through credit, retirement savings or home equity loans. Evelina Sterling, co-author of a book on budgeting finances for infertility treatments, said that 70% of infertility patients cover the costs of the treatments completely out of pocket. She added that some older infertility patients "can"t wait on" the economy to recover to start a family.Carol Hogue, a professor of maternal and child health at Emory University, said there has been a "very predictable" pattern of reduced births during periods of economic recessions dating back to the Great Depression. The Journal-Constitution reports that some people delay planned pregnancy because of concerns over job security, health insurance, income and the cost of raising a child. Statistics from USDA show that the average middle-class family will pay $11,000 to raise a child in the first year, with the largest portion of that cost going to child care. The Agency for Healthcare Research and Quality reported in 2007 -- the latest year for which data are available -- that prenatal care and routine delivery costs about $7,600 after insurance (Cash, Atlanta Journal-Constitution, 5/24).

The Fancier The Cortex, The Smarter The Brain?

Why are some people smarter than others? In a new article in Current Directions in Psychological Science, a journal of the Association for Psychological Science, Eduardo Mercado III from the University at Buffalo, The State University of New York, describes how certain aspects of brain structure and function help determine how easily we learn new things, and how learning capacity contributes to individual differences in intelligence. Cognitive plasticity is the capacity to learn and improve cognitive skills such as solving problems and remembering events. Mercado argues that the structural basis of cognitive plasticity is the cortical module. Cortical modules are vertical columns of interconnected neuronal cells. Across different areas of the cerebral cortex, these columns vary in the number and diversity of neurons they contain. Identifying how cortical modules help us learn cognitive skills may help explain why variations in this capacity occur - that is, why people learn skills at different rates and why our ability to learn new skills changes as we age. Studies examining a number of different species have shown that, on average, a larger cortex predicts greater intellectual capacity. The of this correlation is unclear, but Mercado believes that a "more expansive cortex provides more space within which a larger quantity and greater diversity of cortical modules can be distributed." In other words, Mercado notes that when it comes to intellectual potential, it is not the absolute or even relative size that is important, but how many cortical modules (with various types of neurons) are available. These features of cortical organization and function determine how effectively our brain distinguishes events. This ability to differentiate events may be what enables us to learn cognitive skills. One implication of this proposal is that experience can be as important as genetics in determining intellectual capacity. Specifically, structural changes of cortical modules generated by development and learning experiences may also contribute to individual differences in intelligence. As these networks of neurons develop over time, their diversity increases, leading to further increases in cognitive plasticity. This research has important implications for improving educational techniques and can potentially lead to new methods for rehabilitating patients suffering from brain damage. In addition, understanding how cortical modules function may lead to new ways of increasing intelligence. However, Mercado cautions that "new technologies for increasing cognitive plasticity have ethical implications far beyond those raised by doping in sports." He concludes, "The phrase "changing your mind" may soon take on a whole new meaning." Barbara Isanski Association for Psychological Science
