Oral Bisphosphonates and the Risk of Esophageal Cancer - Medscape, 10/9/12 - "Seven studies, with 19 700 oesophageal cancer cases, met our inclusion criteria. We found a positive relationship between exposure to bisphosphonates and oesophageal cancer, with an odds ratio (OR) of 1.74 with a 95% CI of 1.19–2.55. Heterogeneity was observed (I2 = 85%, P < 0.001). Publication bias was not present. An increased risk of oesophageal cancer was also found in the group exposed to bisphosphonates for a longer period of time, compared with the group who experienced a shorter period of exposure (OR 2.32; 95% CI 1.57–3.43 vs. OR 1.35; 95% CI 0.77–2.39). An increased risk was associated with exposure to Etidronate (OR 1.58; 95% CI 1.12–2.24), but not to Aledronate"
Are we throwing away 'expired' medications too soon? - CNN.com, 10/8/12 - "A new laboratory analysis of eight prescription drugs that expired between 28 and 40 years ago has found that most have remained just as potent as they were on the day they were made ... Overall, the eight drugs included 14 different active ingredients, including aspirin, codeine and hydrocodone"
Tomatoes May Lower Your Risk for Stroke - WebMD, 10/8/12 - "Men who had the highest levels of lycopene in their blood were 55% less likely to have a stroke, compared with men who had the lowest levels of the antioxidant in their blood ... The new study included slightly more than 1,000 men from Finland aged 46 to 65. Researchers measured the level of lycopene in their blood when the study began and followed the men for about 12 years" - See Jarrow Lyco-Sorb (contains Lyco-O-Mato) at Amazon.com.
Prenatal mercury exposure may be linked to risk of ADHD-related behaviors; Fish consumption may be linked to lower risk - Science Daily, 10/8/12 - "Nonoccupational methylmercury exposure comes primarily from eating fish, and the U.S. Environmental Protection Agency and the U.S. Food and Drug Administration have recommended pregnant women limit their total fish intake to no more than two, six-ounce servings per week. However, fish is also a source of nutrients, such as omega-3 fatty acids, which have been shown to benefit brain development, potentially confounding mercury-related risk estimates ... analyzed data from the New Bedford birth cohort, a group of infants born between 1993 and 1998, to investigate the association of peripartum maternal hair mercury levels (n=421) and prenatal fish intake (n=515) with ADHD-related behaviors at age 8 years ... In this population-based prospective cohort study, hair mercury levels were consistently associated with ADHD-related behaviors, including inattention and hyperactivity/impulsivity. We also found that higher prenatal fish consumption was protective for these behaviors"
BPA linked to thyroid hormone changes in pregnant women, newborns - Science Daily, 10/3/12 - "The researchers found that for each doubling of BPA levels, there was an associated decrease of 0.13 micrograms per deciliter of total thyroxine (T4) in mothers during pregnancy, which suggests a hypothyroid effect. For newborn boys, each doubling of BPA levels linked to a 9.9 percent decrease in thyroid stimulating hormone (TSH), indicating a hyperthyroid effect ... studies suggest that small changes in thyroid level, even if they're within normal limits, may still have a cognitive effect"
New study sheds light on cancer-protective properties of milk - Science Daily, 10/3/12 - "lactoferricin4-14 (Lfcin4-14), a milk protein with known health effects, significantly reduces the growth rate of colon cancer cells over time by prolonging the period of the cell cycle before chromosomes are replicated. In a new study, investigators report that treatment with Lfcin4-14 reduced DNA damage in colon cancer cells exposed to ultraviolet (UV) light ... Our data suggest that the effects of Lfcin4-14 in prolonging the cell cycle may contribute to the cancer preventive effect of milk"
Beta-blocker use not associated with lower risk of cardiovascular events - Science Daily, 10/2/12 - "The researchers found that in the prior MI group, the event rates were not significantly different among those with beta-blocker use (489 [16.93 percent]) vs. those without beta-blocker use (532 [18.60 percent]) for the primary outcome, or the secondary outcome (30.96 percent vs. 33.12 percent, respectively). In the CAD without MI cohort, the event rates were not different in those with beta-blocker use (391 [12.94 percent]) vs. those without p-blocker use (405 [13.55 percent]) for the primary outcome, for cardiovascular death, for stroke, and for MI. The event rates were higher in those with beta-blocker use (1,101 [30.59 percent] vs. those without beta-blocker use (1,002 [27.84 percent]) for the secondary outcome and for hospitalization in the propensity score-matched model ... In the risk factors alone group, the event rates were higher in those with beta-blocker use (467 [14.22 percent] vs. those without beta-blocker use (403 [12.11 percent]) for the primary outcome, for the secondary outcome (870 [22.01 percent] vs. 797 [20.17 percent], respectively) but not for MI or stroke. In the propensity score-matched model, there were similar event rates for cardiovascular death and for hospitalization" - Note: Plus beta-blockers increase the chances of diabetes and their side effect profile is intolerable for many. It seems like the only reason they are prescribed is their low cost or for dual drug hypertension therapy. See my telmisartan as first line therapy page. That said, I'm not a doctor.
Low vitamin D levels linked to more severe multiple sclerosis symptoms - Science Daily, 10/2/12 - "For the study, Mowry and her colleagues used data from a five-year study of 469 people with MS. Each year, beginning in 2004, researchers drew blood from, and performed MRIs on, the brains of study participants, looking for both new lesions and active spots of disease, which lit up when a contrast dye was used. The investigators found that each 10-nanograms-per-milliliter increase in vitamin D levels was associated with a 15 percent lower risk of new lesions and a 32 percent lower risk of spots of active disease, which require treatment with medication to reduce likelihood of permanent nerve damage. Higher vitamin D levels were also associated with lower subsequent disability" - See vitamin D at Amazon.com.
Low levels of vitamin D are associated with mortality in older adults - Science Daily, 10/2/12 - "We observed vitamin D insufficiency (defined as blood levels <20 ng/ml), in one third of our study participants. This was associated with nearly a 50 percent increase in the mortality rate in older adults" - See vitamin D at Amazon.com.
Metabolic Syndrome: A Potential and Independent Risk Factor for Erectile Dysfunction in the Chinese Male Population - Urology. 2012 Oct 4 - "our results showed that subjects with MetS had a significantly greater risk of ED (OR 1.34, 95% CI 1.04-1.72; P = .02), especially in middle-age (40-59 years) men (OR 2.43, 95% CI 1.71-3.47; P <.001). Of the MetS components, abnormal fasting blood glucose was the most significantly independent factor of MetS for ED (OR 1.31, 95% CI 1.11-1.55; P = .002)"
Effects of Serum n-3 to n-6 Polyunsaturated Fatty Acids Ratios on Coronary Atherosclerosis in Statin-Treated Patients With Coronary Artery Disease - Am J Cardiol. 2012 Oct 2 - "A low ratio of n-3 to n-6 polyunsaturated fatty acids has been associated with cardiovascular events ... Coronary atherosclerosis in nonculprit lesions in the percutaneous coronary intervention vessel was evaluated using virtual histology intravascular ultrasound in 101 patients at the time of percutaneous coronary intervention and 8 months after statin therapy ... decreases in serum n-3 to n-6 polyunsaturated fatty acid ratios are associated with progression in coronary atherosclerosis evaluated using virtual histology intravascular ultrasound in statin-treated patients with coronary artery disease" - See Mega Twin EPA at Amazon.com and Jarrow Max DHA at Amazon.com.

Dietary and Supplemental Folate and the Risk of Left- and Right-Sided Colorectal Cancer - Nutr Cancer. 2012 Oct 4 - "Epidemiological evidence suggests that folate may lower the risk of colorectal cancer (CRC) although studies have been inconsistent and some have indicated differences in the effects of naturally occurring dietary folate and the synthetic form of this vitamin, folic acid. Most studies to date have considered CRC as a single disease; however, cancers that develop on the left and right sides of the colorectum display important phenotypic differences, suggesting they may also have different risk factors. A population-based case-control study was conducted in Western Australia to examine the relationship between intake of both natural dietary folate and supplements containing folic acid and the risk of left- and right-sided CRC ... There was no association between natural dietary folate intake and risk of either left-or right-sided CRC. Supplement use similarly had no significant effect on right-sided CRC. However, long-term supplement users (4+ yr) were at lower risk of left-sided CRC than those who had not taken supplements (OR = 0.65, 95% CI, 0.50-0.86) and there was a significant trend in risk reduction as duration of use increased" - See folic acid products at Amazon.com.
Dietary phylloquinone intake and risk of type 2 diabetes in elderly subjects at high risk of cardiovascular disease - Am J Clin Nutr. 2012 Oct 3 - "Limited evidence from human and animal studies has suggested that vitamin K has a potentially beneficial role in glucose metabolism and insulin resistance ... Cross-sectional associations were tested in 1925 men and women in the Prevention with the Mediterranean Diet trial ... Dietary intake was collected during each annual visit by using a food-frequency questionnaire, and phylloquinone intake was estimated by using the USDA database ... Dietary phylloquinone at baseline was significantly lower in subjects who developed type 2 diabetes during the study. After adjustment for potential confounders, risk of incident diabetes was 17% lower for each additional intake of 100 μg phylloquinone/d. Moreover, subjects who increased their dietary intake of vitamin K during the follow-up had a 51% reduced risk of incident diabetes compared with subjects who decreased or did not change the amount of phylloquinone intake" - See vitamin K at Amazon.com.
The effect of coffee consumption on blood pressure and the development of hypertension: a systematic review and meta-analysis - J Hypertens. 2012 Oct 1 - "Ovid, MEDLINE (from 1948), EMBASE (from 1988), and all of Web of Science and Scopus ... Low-quality evidence did not show any statistically significant effect of coffee consumption on BP or the risk of hypertension. Given the quality of the currently available evidence, no recommendation can be made for or against coffee consumption as it relates to BP and hypertension"
Losartan improves erectile dysfunction in diabetic patients: a clinical trial - Int J Impot Res. 2012 Aug 30 - "Erectile function was assessed by International Index of Erectile Function (IIEF-5) questionnaire, the percentage of positive responses to sexual encounter profile questions 2 (SEP2), 3 (SEP3) and the global assessment question (GAQ). Losartan or tadalafil or losartan plus tadalafil significantly improved the mean IIEF-5 scores, the percentage of successful penetrations (SEP2), the successful intercourse completions (SEP3) and GAQ (P<0.05). The combination of losartan and tadalafil is more effective than the single-use of losartan or tadalafil (P<0.05). The patients with moderate and mild ED had better response rates to losartan than patients with severe ED" - Note: It seems like the benefit would extend to the entire ARB class of anti-hypertensives but I haven't seen studies on it.
Moderate-Intensity Physical Activity Ameliorates the Breast Cancer Risk in Diabetic Women - Diabetes Care. 2012 Oct 1 - "A population-based case-control study was conducted using 1,000 incident case subjects and 1,074 control subjects ... The association between diabetes and BC risk decreased with increasing tertiles of moderate-intensity physical activity (odds ratio [OR] = 4.9 [95% CI 2.3-10.8]; 3.0 [1.3-6.9]; and 1.0 [0.1-9.2] respectively, for each tertile) (test for interaction = 0.04). Compared with the women in the lowest tertiles, increased risk was observed in those premenopausal women with the highest serum C-peptide, IGF-1, and IGF-1 binding protein 3 levels"
Fish consumption and risk of stroke and its subtypes: accumulative evidence from a meta-analysis of prospective cohort studies - Eur J Clin Nutr. 2012 Oct 3 - "A database was derived from 16 eligible studies (19 cohorts), including 402 127 individuals (10 568 incident cases) with an average 12.8 years of follow-up ... Accumulated evidence generated from this meta-analysis suggests that fish intake may have a protective effect against the risk of stroke, particularly ischemic stroke" - See Mega Twin EPA at Amazon.com and Jarrow Max DHA at Amazon.com.
Magnesium intake and risk of colorectal cancer: a meta-analysis of prospective studies - Eur J Clin Nutr. 2012 Oct 3 - "We performed a literature search on PubMed database through July 2012 to identify prospective studies of magnesium intake in relation to CRC risk ... On the basis of the findings of this meta-analysis, a higher magnesium intake seems to be associated with a modest reduction in the risk of CRC, in particular, colon cancer" - See magnesium supplements at Amazon.com.
The relationship of breakfast skipping and type of breakfast consumed with overweight/obesity, abdominal obesity, other cardiometabolic risk factors and the metabolic syndrome in young adults. The National Health and Nutrition Examination Survey (NHANES): 1999-2006 - Public Health Nutr. 2012 Oct 3:1-10 - "metabolic syndrome (MetS) ... Three breakfast groups were identified, breakfast skippers (BS), ready-to-eat-cereal (RTEC) consumers and other breakfast (OB) consumers, using a 24 h dietary recall ... Relative to the BS, the RTEC consumers were 31%, 39%, 37%, 28%, 23%, 40 % and 4 % less likely to be overweight/obese or have abdominal obesity, elevated blood pressure, elevated serum total cholesterol, elevated serum LDL-cholesterol, reduced serum HDL-cholesterol or elevated serum insulin, respectively. Relative to the OB consumers, the BS were 1.24, 1.26 and 1.44 times more likely to have elevated serum total cholesterol, elevated serum LDL-cholesterol or reduced serum HDL-cholesterol, respectively. Relative to the OB consumers, the RTEC consumers were 22%, 31% and 24% less likely to be overweight/obese or have abdominal obesity or elevated blood pressure, respectively. No difference was seen in the prevalence of the MetS by breakfast skipping or type of breakfast consumed"
