Antimullerian hormone represents a potential way to test ovarian reserve. There are many low AMH level tests or other tests that we currently use to assess the reserve of remaining eggs. None of the tests are perfect, and fertility specialists often use a combination of tests to try to get a better estimate of the size of the remaining egg supply.

Not enough vitamin D: health consequences for Canadians. Schwalfenberg G. Can Fam Physician. 2007 May;53(5):841-54. Review PMID: 17872747 Conclusion Low levels of VTD are considered a major public health problem in Canada, especially during the winter. Those with risk factors should be screened for low 25(OH)D levels and repletion therapy instituted if needed. Researchers have estimated that the oral dose of vitamin D3 to attain and maintain 25(OH)D levels >80 nmol/L is 2200 IU/d if baseline levels are 20 to 40 nmol/L, 1800 IU/d if levels are 40 to 60 nmol/L, and 1160 IU/d if levels are between 60 and 80 nmol/L.64 We need to ensure that patients have healthy blood levels of 25(OH)D to prevent levels of parathyroid hormone from rising and to maximize absorption of calcium, magnesium, and phosphate. Positive effects on bone are marginal at best unless patients consume at least 800 IU/d of VTD. The emerging and exciting role of the VTD receptor and the actions of VTD in maintaining health in other cell types have become more apparent during the last decade.

Independent association of low serum 25-hydroxyvitamin d and 1,25-dihydroxyvitamin d levels with all-cause and cardiovascular mortality.\nDobnig H, Pilz S, Scharnagl H, Renner W, Seelhorst U, Wellnitz B, Kinkeldei J, Boehm BO, Weihrauch G, Maerz W.\nArch Intern Med. 2008 Jun 23;168(12):1340-9.\nPMID: 18574092

Scientists have long known that a lack of vitamin D can weaken our bones. A new study shows that low levels of this nutrient may also be linked to a higher chance of dying early from heart and circulation problems, as well as other causes.

Low levels of vitamin D may raise a person's risk of premature death, a study by Johns Hopkins researchers shows. The research followed other recent studies showing low levels of vitamin D are linked to certain cancers, diabetes, and bone and immune system problems, but this is the first research to connect vitamin D deficiency to a higher risk of death

March 11, 2009 -- Low vitamin D levels greatly increase a teenager's risk of diabetes and heart disease, Johns Hopkins researchers find. It is becoming clear that adults who get too little vitamin D are at higher risk for diabetes and heart disease. Now, it appears vitamin D levels also affect these risks earlier in life, say Johns Hopkins researchers Jared P. Reis, PhD, and colleagues.

Low vitamin d levels predict stroke in patients referred to coronary angiography.\nPilz S, Dobnig H, Fischer JE, Wellnitz B, Seelhorst U, Boehm BO, März W.\nStroke. 2008 Sep;39(9):2611-3. Epub 2008 Jul 17.\nPMID: 18635847 \ndoi: 10.1161/STROKEAHA.107.513655

Keeping a high and low blood sugar levels chart can help the patient learn how to handle his problem and prevent the risk of heart disease, high blood pressure, strokes, kidney illness, blindness and gangrene that go with this ever more typical ailment.

Feb. 23, 2009 -- A walk in the sun may be better than popping a vitamin C tablet for boosting your chances of preventing the common cold or flu.\n\nA new study adds to mounting evidence that vitamin C may have been stealing the spotlight all these years from the real cold fighter, vitamin D.

The prostate is the gland below a man's bladder that produces fluid for semen. Prostate cancer is the third most common cause of death from cancer in men of all ages. It is rare in men younger than 40. Levels of a substance called prostate specific antigen (PSA) is often high in men with prostate cancer. However, PSA can also be high with other prostate conditions. Since the PSA test became common, most prostate cancers are found before they cause symptoms. Symptoms of prostate cancer may include Problems passing urine, such as pain, difficulty starting or stopping the stream, or dribbling Low back pain Pain with ejaculation Prostate cancer treatment often depends on the stage of the cancer. How fast the cancer grows and how different it is from surrounding tissue helps determine the stage. Treatment may include surgery, radiation therapy, chemotherapy or control of hormones that affect the cancer.
