Can Extra Time Outdoors When Young Reduce Nearsightedness?

Posted 6 days ago by Drugs.com

THURSDAY, Dec. 1, 2016 – Spending more time outside early in life may offer some protection against nearsightedness, a new study suggests. The European study authors suspect that additional exposure to the sun's ultraviolet B (UVB) rays may play a role in reducing nearsightedness – the inability to see clearly at a distance, also known as myopia. "We found that higher annual lifetime UVB exposure, directly related to time outdoors and sunlight exposure, was associated with reduced odds of myopia," the study authors wrote. "Exposure to UVB between ages 14 and 29 years was associated with the highest reduction in odds of adult myopia," they added. The findings don't "add a lot to the picture" of current research that links nearsightedness to time outdoors, said Ian Morgan, a vision researcher and visiting fellow at Australian National University. He was not involved with the study. ... Read more

Vitamin D May Affect Breast Cancer Survival

Posted 10 Nov 2016 by Drugs.com

THURSDAY, Nov. 10, 2016 – Vitamin D levels may affect breast cancer patients' chances of survival, a new study suggests. Researchers analyzed data from nearly 1,700 breast cancer patients in California and found that higher vitamin D levels at diagnosis were associated with better overall survival. This link was strongest in premenopausal women. Researchers found lower vitamin D levels in patients with advanced-stage tumors and the lowest levels in premenopausal women with triple-negative cancer. Triple-negative cancer is the most common type of breast cancer found in women with changes in a gene called BRCA1. While the findings are consistent with previous studies, other factors may play a role and the study does not prove cause and effect, the researchers noted. "Our findings provide compelling observational evidence for inverse associations between vitamin D levels and risk of ... Read more

Vitamin D Levels May Fall When Women Stop Taking Birth Control

Posted 4 Aug 2016 by Drugs.com

THURSDAY, Aug. 4, 2016 – Vitamin D levels may drop after women stop using birth control pills or other contraceptives with estrogen, researchers report. The vitamin is involved in the immune system and in managing calcium in the blood, which influences bone health. The body produces it when exposed to sunlight. During pregnancy, women produce higher amounts of vitamin D to help fetal bone development and are at increased risk of vitamin deficiency, according to the researchers. "Our findings indicate women may run the risk of developing vitamin D deficiency just when they want to become pregnant," said study first author Dr. Quaker Harmon. She is a postdoctoral fellow at the U.S. National Institute of Environmental Health Sciences. "For women who are planning to stop using birth control, it is worth taking steps to ensure that vitamin D levels are adequate while trying to conceive and ... Read more

Cow's Milk Allergy in Childhood May Lead to Weaker Bones: Study

Posted 20 Apr 2016 by Drugs.com

WEDNESDAY, April 20, 2016 – Children who are allergic to cow's milk may have weaker bones than kids with other food allergies, a small study suggests. Cow's milk allergy is the most common childhood food allergy in the United States, affecting up to 3 percent of children, the researchers said. The main treatment is elimination of cow's milk and dairy products – which are major sources of the calcium kids need to build strong bones. This new study detected low bone density in 6 percent of 52 children with a long-term milk allergy. "Prepubertal children with persistent cow's milk allergy have a lower bone mineral density and calcium intake compared with similarly aged children with food allergies other than cow's milk," said study co-author Genevieve Mailhot. She is an associate professor at the CHU Sainte-Justine Research Center at the University of Montreal. The study findings don't ... Read more

Tanning May Limit Skin's Ability to Produce Vitamin D: Study

Posted 4 Apr 2016 by Drugs.com

MONDAY, April 4, 2016 – While the sun helps the body make vitamin D, a new study says that too much exposure might actually lower the levels of the essential vitamin. Tan skin may provide some protection against the sun's harmful UV rays, but this increase in pigment blocks vitamin D synthesis and limits the skin's ability to produce vitamin D, according researchers in Brazil. "Our findings suggest that skin tanning, which is a natural protection against the harmful effects of UV irradiation, limits the progressive rise in serum vitamin D towards optimal concentrations," said study author Dr. Francisco Bandeira, of the University of Pernambuco Medical School in Recife, Brazil. For the study, researchers examined nearly 1,000 males and females from Recife who were between 13 and 82 years old. All had significant daily sun exposure and none routinely used sunscreen or took vitamin D ... Read more

Be Wary of Imported Supplements: FDA

Posted 9 Mar 2016 by Drugs.com

WEDNESDAY, March 9, 2016 – You could be putting your health at risk if you buy imported dietary supplements and nonprescription drug products, the U.S. Food and Drug Administration warns. Health fraud scammers often sell such products at ethnic or international stores, flea markets, swap meets or online, Cariny Nunez, a public health adviser in the FDA's Office of Minority Health, said in an agency news release. This may be because many people who shop at these places have poor English-language skills and limited access to health care services and information, she suggested. "These scammers know that ethnic groups who may not speak or read English well, or who hold certain cultural beliefs, can be easy targets," she added. For example, Native American, Hispanic, Asian and black people may have a long tradition of using herbal – or so-called "natural" – products, and many of these ... Read more

Vitamin D a No Go for Arthritic Knees, Study Finds

Posted 8 Mar 2016 by Drugs.com

TUESDAY, March 8, 2016 – Vitamin D supplements didn't relieve pain or slow the progression of knee osteoarthritis in a new study, even though the patients involved had low levels of the vitamin. Osteoarthritis is a progressive disease, and currently no treatment is available that will stop the loss of cartilage. Eventually, many patients are headed for knee replacements, the Australian researchers said. "These data suggest a lack of evidence to support vitamin D supplementation for slowing disease progression or structural change in knee osteoarthritis," said lead researcher Dr. Changhai Ding, a professor at the University of Tasmania in Hobart. The use of vitamin D supplements to reduce pain and slow the progression of knee osteoarthritis has been controversial in the past, with studies showing conflicting results, he said. This new study put vitamin D supplements to the test by ... Read more

Low Prenatal Vitamin D Linked to Later MS in Offspring

Posted 8 Mar 2016 by Drugs.com

MONDAY, March 7, 2016 – Children of mothers with too little vitamin D during their pregnancy may have a higher risk of developing multiple sclerosis when they reach adulthood, a new study suggests. One expert in the United States said that the findings need to be interpreted with caution, however. "We cannot say from this study that low vitamin D levels cause MS in women's offspring," said Dr. Daniel Skupski, chair of obstetrics and gynecology at NewYork-Presbyterian/Queens hospital in New York City. All the study points to is an association between the two, he stressed. What the research does do, Skupski said, is "set the stage" for further research to see if getting more vitamin D in pregnancy might lower people's lifetime risk for multiple sclerosis. Multiple sclerosis affects a person's brain and spinal cord by damaging the myelin sheath, the insulating layer that surrounds and ... Read more

Vitamin D While Pregnant Won't Boost Most Infants' Bone Health, Study Says

Posted 2 Mar 2016 by Drugs.com

WEDNESDAY, March 2, 2016 – Taking vitamin D supplements during pregnancy does not improve a baby's bone density, according to a new British study. But for babies born in the winter, "sunshine vitamin" supplementation may help counteract low levels caused by seasonal loss of sunlight, the researchers said. Some previous studies have suggested that higher vitamin D in mothers during pregnancy are associated with greater bone density in babies, and guidelines in the United Kingdom recommend vitamin D supplements for all pregnant women. However, the American College of Obstetricians and Gynecologists only recommends supplements for mothers-to-be who are deficient in vitamin D. This study included more than 1,100 British women, 14 to 17 weeks pregnant, with low to normal levels of vitamin D. Half took a 1,000 International Unit vitamin D capsule daily until they had their baby, while the ... Read more

Low Vitamin D Levels May Signal More Aggressive Prostate Cancer

Posted 2 Mar 2016 by Drugs.com

WEDNESDAY, March 2, 2016 – Prostate cancer may be more aggressive in men who are deficient in vitamin D, new research suggests. A study of nearly 200 men having their prostate removed found those with low vitamin D levels were more likely to have rapidly growing tumors than those with normal levels of the "sunshine" vitamin. "If men with vitamin D deficiency are more likely to have [more advanced disease] at the time of prostate surgery, then perhaps men should be tested for this when they are diagnosed with prostate cancer and subsequently supplemented with vitamin D if they are deficient," said researcher Dr. Adam Murphy. He is an assistant professor of urology at Northwestern University in Chicago. However, another expert isn't ready to go that far. This study can't prove that vitamin D deficiency causes aggressive prostate cancer, only that the two are associated, said Dr. Anthony ... Read more

Prenatal Diet Rich in Vitamin D May Cut Allergy Risk in Kids: Study

Posted 17 Feb 2016 by Drugs.com

WEDNESDAY, Feb. 17, 2016 – Children born to women who eat vitamin D-rich foods during pregnancy have a lower risk of hay fever, but vitamin D supplements do not have the same effect, a new study suggests. The new study included more than 1,200 mothers and their children. The children were followed until they were about 7 years old. A diet with higher levels of vitamin D – equivalent to the amount in an 8-ounce serving of milk each day – during pregnancy was associated with a 20 percent lower risk of hay fever in school-age children. Taking vitamin D supplements did not reduce the risk, according to the study published Feb. 11 in the Journal of Allergy and Clinical Immunology. "Expectant mothers have questions about what they should eat during pregnancy, and our study shows that it's important to consider the source of nutrients in a mother's diet," study leader Dr. Supinda ...

Could High-Dose Vitamin D Help Fight Multiple Sclerosis?

Posted 31 Dec 2015 by Drugs.com

WEDNESDAY, Dec. 30, 2015 – High-dose vitamin D appears safe for people with multiple sclerosis, and it may help quiet the immune system hyperactivity that marks the disease, a small clinical trial finds. The study, published online Dec. 30 in Neurology, bolsters evidence that vitamin D might benefit people with MS. But clinical trials are still underway to answer the big question: Does taking vitamin D improve MS symptoms and alter the course of the disease? The current study shows only that high doses – 10,400 IU a day – reduce the proportion of certain immune-system cells that have been implicated in the MS disease process. "I'm not going to make any claims beyond that," said senior researcher Dr. Peter Calabresi, a professor of neurology at Johns Hopkins University in Baltimore. "We don't have enough data here to guide clinical practice," he stressed. Bruce Bebo, executive vice ... Read more

Vitamin D Deficiency Might Be Tied to Erectile Dysfunction

Posted 13 Nov 2015 by Drugs.com

FRIDAY, Nov. 13, 2015 – Low levels of vitamin D may be associated with erectile dysfunction, a new study suggests. Researchers analyzed data from more than 3,400 American men, age 20 and older, who did not have heart disease. Thirty percent were vitamin D deficient, which means their levels of the "sunshine vitamin" were below 20 nanograms per milliliter of blood. And 16 percent had erectile dysfunction. Vitamin D deficiency was present in 35 percent of men with erectile dysfunction, compared with 29 percent of those without erectile dysfunction, the study found. "Vitamin D deficiency is easy to screen for and simple to correct with lifestyle changes that include exercise, dietary changes, vitamin supplementation and modest sunlight exposure," study lead investigator Dr. Erin Michos, an associate professor of medicine at Johns Hopkins University School of Medicine, said in a university ...

Scientists Pinpoint What Level of Vitamin D Promotes Heart Health

Posted 12 Nov 2015 by Drugs.com

THURSDAY, Nov. 12, 2015 – Researchers say they've identified the minimum level of vitamin D needed for good heart health. Previous research has shown that vitamin D deficiency increases the risk of heart disease, heart attack and stroke, but the level of deficiency associated with such risk was unclear, the researchers said. Having a vitamin D level anywhere above 15 nanograms per milliliter is fine for heart health, according to a team at the Intermountain Medical Center Heart Institute in Salt Lake City. "Although vitamin D levels above 30 were traditionally considered to be normal, more recently, some researchers have proposed that anything above 15 was a safe level. But the numbers hadn't been backed up with research until now," lead researcher Dr. J. Brent Muhlestein, co-director of cardiovascular research, said in an institute news release. "Even if any level above 15 is safe, ... Read more

Many Hospital Patients Not Asked About Supplements: Study

Posted 23 Jun 2015 by Drugs.com

TUESDAY, June 23, 2015 – Most hospitalized Americans aren't asked if they take dietary supplements, such as multivitamins, a new study suggests. "If clinicians are unaware of possible drug-[dietary supplement] reactions, they may unknowingly provide a treatment plan or prescribe medications that could have an adverse reaction or interactions with the dietary supplement," said study author Dr. Paula Gardiner. She is assistant director of Boston Medical Center's program for integrative medicine and health care disparities. "Dietary supplements also affect physiological processes in the body and could have an impact on medical procedures like surgery, chemotherapy, blood work and many other treatments or procedures," she added in a medical center news release. Nearly 18 percent of American adults (more than 40 million) take dietary supplements, according to the 2012 National Health ... Read more
