New Antipsychotics Old Results

Risks Found for Youths in New Antipsychotics

A new government study published Monday has found that the medicines most often prescribed for schizophrenia in children and adolescents are no more effective than older, less expensive drugs and are more likely to cause some harmful side effects. The standards for treating the disorder should be changed to include some older medications that have fallen out of use, the study’s authors said.

“I think the reason the use of these newer drugs has gone up so fast is that there was this widespread assumption that they were safer and more effective than what we had before,” Dr. McClellan said. “Well, we’re seeing now that that’s not the whole story.”

Study Finds No Measurable Benefit to Flu Shots

Do Flu Shots For The Elderly Save Lives? Just Washing Hands Works Better, Says Study

The widely-held perception that the influenza vaccination reduces overall mortality risk in the elderly does not withstand careful scrutiny, according to researchers in Alberta. The vaccine does confer protection against specific strains of influenza, but its overall benefit appears to have been exaggerated by a number of observational studies that found a very large reduction in all-cause mortality among elderly patients who had been vaccinated.

The study included more than 700 matched elderly subjects, half of whom had taken the vaccine and half of whom had not. After controlling for a wealth of variables that were largely not considered or simply not available in previous studies that reported the mortality benefit, the researchers concluded that any such benefit “if present at all, was very small and statistically non-significant and may simply be a healthy-user artifact that they were unable to identify.”

“Over the last two decades in the United Sates, even while vaccination rates among the elderly have increased from 15 to 65 percent, there has been no commensurate decrease in hospital admissions or all-cause mortality

Study challenges notion of ‘pandemic’ flu

Peter Doshi, a graduate student in the History, Anthropology, and Science, Technology and Society Program at MIT, based his study on an analysis of more than a century of influenza mortality data. He found that the peak monthly death rates in the 1957-1958 and 1968-1969 pandemic seasons were no higher than–and were sometimes exceeded by–those for severe nonpandemic seasons.

Doshi says the pandemic-equals-extreme-mortality concept appears to be a generalization of a single data point: the 1918 season, a period in which “doctors lacked intensive care units, respirators, antiviral agents and antibiotics.” He argues that “had no other aspect of modern medicine but antibiotics been available in 1918, there seems good reason to believe that the severity of this pandemic would have been far reduced.”

As may be expected given improvements in living conditions, nutrition and other public health measures, influenza death rates substantially declined across the 20th century. Doshi calculates an 18-fold decrease in influenza deaths between the 1940s and 1990s, a trend that began far before the introduction of widespread vaccination.

Eating Breakfast Keeps Teenagers Leaner

Breakfast ‘keeps teenagers lean’

In a five year study of more than 2,000 youngsters, those who skipped breakfast weighed on average 5lbs (2.3kg) more than those who ate first thing. This was despite the fact that the breakfast-eaters consumed more calories in the course of the day. But the study in Pediatrics found they were likely to be much more active.

The University of Minnesota research adds weight to a growing body of evidence that those who eat breakfast – whether young or old – are leaner than those who do not.
…
“The real problem is the profusion of messages about obesity. We need to make clear that eating regular meals is vital – and that a proper breakfast is very important. “If you eat well first thing, you’ll feel brighter, you’ll have more get up and go – and that will mean you’ll expend more energy.”

Teenagers are not the only ones who may benefit from sitting down to a proper breakfast. In a study of nearly 7,000 middle-aged people in Norfolk, a team from Cambridge University found that those who ate the most in the morning put on the least amount of weight.

Exercise to Reduce Fatigue

Low-Intensity Exercise Edges Out Fatigue — Without Requiring Lots of Sweat

If fatigue hounds your days, a little exercise may shoo it away without leaving you drenched with sweat. So say University of Georgia researchers. In a new study, they report that healthy young adults who say they’re tired all the time got an energy boost from a low-intensity workout plan.

Here’s all it took: three sessions per week of pedaling a stationary bicycle at a mild pace. They didn’t need to train every day, and they didn’t push themselves too far — just far enough to shake their fatigue

As I have said before, I have found exercise reduces fatigue myself.
