Washington - Leaving nothing to chance and taking no vote for granted, the two US presidential candidates kept up a frenetic pace Saturday as they plunged into the last weekend of campaigning before Tuesday's election.

Democratic Party presidential candidate Barack Obama is increasing his lead over Republican rival John McCain as the campaign enters its final phase, according to a poll published Saturday by the Washington Post.

It said 53 per cent of the electorate would vote for Obama, compared to 44 per cent for McCain. Obama also led in several key states seen as decisive in the election.

A recent study conducted by Dr. Jan Shifren, of Massachusetts General's Obstetrics and Gynecology Service and team surveyed 32,000 women aged 18 and older, across the U.S. The participants were asked standardized questions about their sexual health. The survey also gauged the women’s distress related to their sex lives — including feelings of anger, guilt, frustration, and worry.

Overall, 43.1% women reported some kind of sexual problem; 39% had diminished desire; 26% had arousal problems, and 21% had problems with achieving orgasm.

But luckily only 12% suffered from personal distress due to these problems.

The latest from writer-director Kevin Smith , “Zack and Miri Make a Porno,” is a raunch-heavy comedy. The story revolves around two childhood friends who decide to make a dirty movie together. What compels them to do so and how they fall in love along the way expresses the comic as well as satirical character of the movie.

Zack and Miri played Seth Rogen and Elizabeth Banks met in kindergarten. They share a platonic love as well as a room since high school, which is a decade ago. Their room  nearly shanty, infested by rats is a rented accommodation in Pittsburgh.  Both work at a franchise coffee shop. Both Zack and Miri are presented to be underachievers.

A recent study conducted on 40,000 mothers and their babies found that 1-in-5 women gain too much weight during pregnancy, which doubles the chances of their babies gaining 9-pounds or more.

The findings of the research by Dr. Hillier M.D., of Kaiser Permanente Northwest and colleagues have been published  in the November issue of Obstetrics and Gynecology.

The research also found these babies are prone to obesity later in life.

"The take-home message is that all pregnant women need to watch their weight gain and it is especially important for women who have risk factors like gestational diabetes," said Dr Hiller
