There is no need for more than two hours of fasting before inguinoscrotal region surgery. Further studies in surgical patients should help to substantiate the safety and clinical benefits of this new concept.

That's because nicotine suppresses appetite and boosts a smoker's metabolism. But a new meta-analysis shows that women who quit smoking while receiving treatment for weight control are better able to control their weight gain and are more successful at quitting cigarettes. The finding disproves clinical guidelines that say trying to diet and quit smoking at the same time will sabotage efforts to ditch cigarettes.

Men and women carrying the CC genotype demonstrated higher body mass index scores and a higher incidence of obesity, but only if they consumed a diet high in saturated fat. These associations were seen in the apolipoprotein A-II gene promoter.

Rising obesity is associated with the lower likelihood of having optimal blood pressure and blood sugar levels. Another study indicates that weight loss may correct structural heart damage in obese patients.

While those who misperceived their need for weight loss thought they were healthier than others their age, they had the same risk factors for heart disease as other obese patients. Those who misperceived their body size were less likely to exercise and see a physician than their counterparts who accurately perceived their body size.
