Short-term use of IV devices is common — and risky — study shows

Many hospital patients get medicine or nutrition delivered straight into their bloodstream through a tiny device called a PICC. In just a decade, it’s become the go-to device for intravenous care. But a new study finds that one in every four times a PICC gets inserted, the patient didn’t need it long enough to justify the risks it can pose. And nearly one in ten of those patients suffered a complication linked to the device.

Molecular Trojan horse delivers chemotherapeutic drug to cancer cells

Researchers have discovered a way for chemotherapy drug paclitaxel to target migrating, or circulating, cancer cells, which are responsible for the development of tumor metastases. Until now, paclitaxel has only been used to target rapidly dividing cancer cells. The team was successful in getting the drug to piggyback on 123B9, an agent they devised to target an oncogene called EphA2.

The Weird Reason Why Stress Sweat Might Smell Worse Than Exercise Sweat

Some people do notice they give off an extra-foul stench when they’re feeling overwhelmed or anxious. A little background info: The purpose of sweating is to regulate body temperature; with stress sweat, a shift in hormones, such as adrenaline, causes the body to have a fightor-flight response that leads to excessive sweating. But there are two main types of sweat glands, and they produce different types of sweat. When you exercise, you produce sweat, consisting mainly of water and salt, from eccrine glands all around the body that open on the surface of the skin in order to cool you down. When you’re stressed out, sweat gets produced by apocrine glands, which are located in spots on the body that have lots of hair follicles. While all sweat is odorless, the perspiration produced in the areas where we have hair follicles, such as the armpits and the groin, smells bad when it leaves the follicles and combines with bacteria on the skin’s surface. This sweat also contains fats and proteins, which the bacteria likes to feed on.

So, controlling stress in general will keep body odor at bay in high-anxiety moments. Have stress management techniques—some deep breathing, a quick meditation in a quiet room at the office, you know the drill—in place that you can use, say, before a big presentation. And avoid overdoing it on caffeine during stress spirals; it can cause blood pressure and heart rate to rise and can make stress symptoms even worse.

Also, if you’re worried about stress sweat ruining a moment, try a clinical strength antiperspirant-deodorant (tons of options are available at the drugstore; we like Secret Clinical Strength) at night, when your armpits are drier and the pores will take in the product better—and reapply in the morning.

What to Do If Working Out Is Killing Your Knees

Knee pain is a common exercise complaint. The knee is an intricate joint, involving bones, menisci, muscles, tendons, and ligaments all supporting the joint. If there is damage or stress to any of these components, you may have achy knees. Plus, many physical activities—running, jumping, stretching, bending—can put a lot of strain, impact, or body weight directly on the knees, and in turn, cause pain while you work out. This is common among weekend warriors who work out intensely but inconsistently. You can also develop tendonitis over time if you’re regularly doing these motions.

Some causes of knee pain are a bit more serious, however. A common cause in young people, especially those who exercise or play high-impact sports, is patellofemoral pain syndrome. Also known as runner’s knee, this syndrome is characterized by pain in the soft tissues and bone around the kneecap. Treatment may involve rest and physical therapy to stabilize the knee joint. Or, it’s possible that the cartilage in your knees has suffered some wear and tear with use and age (osteoarthritis), in which case you may have to change up your workouts and incorporate more low-impact activities, like swimming, using the elliptical, or cycling, to lessen the pain.

Doing away with general knee pain from exercising could just be a matter of perfecting your form when you, say, run or do squats and lunges. A few sessions with a certified personal trainer or physical therapist can help you learn these basic movements so that you’re doing them with correct form every time and not putting yourself at risk of injury or long-term damage. Or you may need to do physical therapy to improve your knee stabilization. But because there are so many possible reasons for knee pain, your best bet is to talk to your doctor so you can get the specific help you need.

Sweet, bitter, fat: Genetics play a role in kids’ snacking patterns

The types of snacks a child chooses could be linked to genetics, a new study found. The study investigated whether genetic variants in taste receptors related to sweet, fat and bitter tastes influence the snacks preschoolers choose and found nearly 80 per cent carried at least one of these genotypes that could predispose them to poor snacking habits. These findings could help parents tailor their kids’ diets based on their genetics of taste.
