Feeding tubes are often used for infant and geriatric care. But in our inventive and odd society, they have somehow found a market with aspiring models and others who insist on losing weight any way they can. Do these people have have any idea about the medical risks? Why are medical professionals enabling these neuroses? Two abstracts and the news article that prompted this below.

WHO (2007) recommended that to reduce microbial risks, powdered infant formula should be reconstituted with water at temperatures > 70 °C, and that such feeds should be used within 2 h of preparation. .
Bacterial biofilm formation by members of the Enterobacteriaceae was ca. 105106 cfu/cm after 24 h. Negligible biofilm was detected for Acinetobacter gensp. 13; ca. 10 cfu/cm, whereas Cr. sakazakii strain ATCC 12868 had the highest biofilm cell density of 107 cfu/cm. Biofilm formation did not correlate with capsule production, and was not inhibited on silver-impregnated tubing. Bacteria grew in the tube lumen to cell densities of 107 cfu/ml within 8 h, and 109 cfu/ml within 24 h. It is plausible that in vivo the biofilm will both inoculate subsequent routine feeds and as the biofilm ages, clumps of cells will be shed which may survive passage through the neonate’s stomach. Therefore biofilm formation on enteral feedingtubes constitutes a risk factor for susceptible neonates.

We examined the external surfaces of the gastric portion of nasogastric tubes recovered from hospitalized patients. Most of these surfaces were covered with a thick amorphous biofilm which was shown to be largely composed of microbial microcolonies in which individual cells were enclosed in their exopolysaccharide glycocalyces. Bacteria of many different morphotypes and some yeast cells were found in a fibrillar matrix that appeared to mediate their attachment to the silastic tubing. Within these mature biofilms some microcolonies were structurally intact and apparently vigorous, while others were composed largely of dead cells and empty cell walls. We conclude that nasogastric tubes that remain in patients for as short a time as one day are heavily colonized by a rich variety of biofilm-forming bacteria and yeasts.
We must stop feeding unhealthy obsession with looks

Imagine walking around with a tube that goes through your nose and passes through your esophagus, right down into your stomach.
A nasogastric tube, or feeding tube, provides nourishment. Its usually reserved for patients with medical challenges. But now, feeding tubes are the new dietary rage.
Last week, the New York Times ran a story about crash-dieting brides willing to undergo the 10-day K-E diet that costs $1,500 and requires a doctors supervision.
Its an eyebrow-raising trend, but we know where it stems from. The pressure on brides and women in general to look a certain way is not imaginary.
When I was planning my wedding, every magazine had a get-fit-quick plan for brides. Looking a certain way was an ongoing dialogue.
There was no escape from the endless pictures of Kate Middleton and even short-term bride Kim Kardashian. Theres nothing wrong with losing weight healthfully, but magazines, TV, runways and society seem to scream, Lose weight. Look perfect.
Perfection is expected of women, not just by men, but by other women, because this is the culture of thinspiration and bodysnarking. We feel so insecure about our own image that we pick on others. I am no exception. Ive been picked on for being too skinny and having acne. But Ive also scoffed at the girls in too-short skirts and v-necks down to there. Its the bullied becomes the bully complex.
This is why Ashley Judds puffy face became a thing to talk about recently. We all wondered if she was a victim of botched plastic surgery or a crazy beauty treatment. I shamefully admit I gave her face the questioning side-eye. And I know better. Still, its easy to get caught up in the crazy talk.
In her essay for the Daily Beast, the actress blames the puffiness on steroids she was prescribed for an illness and takes us all to task over our obsession.
The Conversation about women happens everywhere, publicly and privately, she wrote. We are described and detailed, our faces and bodies analyzed and picked apart, our worth ascertained and ascribed based on the reduction of personhood to simple physical objectification. Our voices, our personhood, our potential, and our accomplishments are regularly minimized and muted.
She admits that she falls for it too. Its one of those things in which none of us is completely innocent. And we must do better by our little girls and women.
Judd says men and boys face the same pressure when it comes to fulfilling an image of masculinity. I think there are unfair expectations for guys. But I dont think its the same as what women go through.
On TV you can see a chubby, balding guy like Modern Familys Jay Pritchett with the curvy and gorgeous Gloria. There is no reverse of that, not even in cartoon land with Family Guy. As long as a guy is funny, charming or talented, it almost doesnt matter how he looks.
Adele, one of the most talented singers in the world, was called fat by designer Karl Lagerfeld. But Ruben Studdard, once American Idols winner, was considered a teddy bear.
Rapper Rick Ross, a Billboard regular known for his big belly, graced the cover of Vibe magazines sex issue last summer, shirtless. He has been called a sex symbol. But Jessica Simpson bares her naked, pregnant body on the cover of Elle and gets criticized for her weight. Its called pregnant.
There is no way for women to mold themselves into this image of perfection the media pushes. But there is a way for us to quit feeding into this unhealthy diet of body shaming and accept ourselves as well as one another.
We cannot be reduced to our bodies, our faces and our clothes. We are much more than that. And it should be reflected in our conversations.
