Aerobic exercise may help guard against dementia
According to a small study, aerobic exercise may strengthen memory and thinking skills in older adults with mild cognitive impairment (MCI). The study included 16 people, average age 63, who did aerobic workouts such as on a treadmill, stationary bike or elliptical training. They worked out four times a week for six months. There was also a control group of 19 people, average age 67, who did stretching exercises four times a week for six months but no aerobic activity. All of the participants had mild cognitive impairment. After six months, brain scans revealed that those in the aerobic exercise group had greater increases in brain volume than those in the stretching group. Those in the exercise group also showed significant improvement in thinking and memory after six months, while those in the stretching group did not, according to the researchers.

Tuberculosis virulence factor identified, may be target for new drug
Scientists have discovered the mechanism that hijacks the immune system's response to tuberculosis, revealing an important new drug target for the disease that kills more than 1 million people each year. When Mycobacterium tuberculosis enters a human cell, the presence of its DNA and a molecule that it makes called c-di-AMP alert the cell to the bacteria's presence. The human cell responds by creating a messenger molecule, cGAMP, which signals nearby cells to mount an immune response to kill the tuberculosis bacteria. But the tuberculosis bacterium has found a way to turn off the call for help. By producing a protein called cyclic dinucleotide phosphodiesterase (CdnP), the bacterium reduces the concentration of the cell's messenger molecule, cGAMP, a nucleic acid. This accentuates the effect of the human phosphodiesterase ENPP1, an enzyme that cleaves nucleic acids, to quickly degrade any already-made cGAMP and turn off the immune response early.

Yoga called good medicine for high blood pressure
According to a new study, yoga may help reduce blood pressure in people who are at risk for developing hypertension. The new study included 60 people who had slightly elevated blood pressure but were otherwise healthy. The participants were randomly assigned to either practice hatha yoga while also making conventional lifestyle changes, or to just make the lifestyle changes (the "control" group). The lifestyle changes included moderate aerobic exercise, eating a healthier diet and quitting smoking. The yoga group, average age 56, received yoga instruction for a month and then did the activities such as stretching, controlled breathing and meditation at home. After three months, those in the yoga group had notable decreases in blood pressure, while those in the control group did not, the investigators found.

Global efforts to combat tb epidemic falling short
Countries around the world need to work harder to combat tuberculosis infections and deaths, a new World Health Organization report says. Nations across the globe have pledged to reduce tuberculosis (TB) infections by 80 percent and TB deaths by 90 percent by 2030, but they must work faster if they want to meet these goals, according to the WHO. The global response to the TB epidemic did manage to save more than 3 million lives last year, the WHO report revealed. But new data collected from India suggests estimates about the total burden of the disease were too low. In 2015, an estimated 10.4 million people were newly diagnosed with TB. Of these people, 60 percent were from India. The WHO report suggests that disparities exist in many countries, which may prevent people with the infection from gaining access to cost-effective diagnosis and treatments.

Drug-Resistant germs thrive in America's corroding water systems
The thousands of miles of aging, corroding pipes that bring water to Americans each day may be home to dangerous drug-resistant bacteria, a new report warns. These harmful bacteria include legionella, which causes Legionnaires' disease; pseudomonas, which can trigger pneumonia; and mycobacteria, which can cause tuberculosis and other illnesses, the researchers said. Many of the bacteria that triggered these cases may already be resistant to one or more antibiotics, as was seen in 1 percent to 2 percent of hospitalizations. Not only are antibiotic-resistant bacteria much more dangerous for patients, but treating such cases boosts costs by 10 percent to 40 percent.
