Obesity Increases Risk Of Prostate Cancer Recurrence For Both Blacks And Whites - Science Daily, 8/17/09 - "We found that higher BMI was associated with significantly increased risk of cancer recurrence for both blacks and whites ... Obesity is associated with more estrogen and less testosterone, and it may be that lower testosterone promotes more aggressive tumors as recent studies have suggested ... In addition, Jayachandran says alteration in the production of other hormones, like insulin, insulin-like growth factor or leptin, which occur in obese men, may also be involved in the development of more aggressive tumors"

Carnitine Supplements Reverse Glucose Intolerance In Animals - Science Daily, 8/17/09 - "After just eight weeks of supplementation with carnitine, the obese rats restored their cells' fuel- burning capacity (which was shut down by a lack of natural carnitine) and improved their glucose tolerance, a health outcome that indicates a lower risk of diabetes ... These results offer hope for a new therapeutic option for people with glucose intolerance, older people, people with kidney disease, and those with type 2 diabetes (what used to be called adult-onset diabetes) ... Carnitine is a natural compound known for helping fatty acids enter the mitochondria, the powerhouses of cells, where fatty acids are "burned" to give cells energy for their various tasks. Carnitine also helps move excess fuel from cells into the circulating blood, which then redistributes this energy source to needier organs or to the kidneys for removal" - See l-carnitine at Amazon.com.

Low Choline Levels In Pregnant Women Raise Babies' Risk For Brain And Spinal-cord Defects, Study Shows - Science Daily, 8/16/09 - "Choline, an essential nutrient found in egg yolks, soy, wheat germ and meats, was the only nutrient measured whose blood levels were linked to risk of neural tube defects" - See citicholine at Amazon.com.

High-fat diets linked to poor mental function - Nutra USA, 8/14/09 - "High consumption of fatty foods may reduce both cognitive function and physical endurance ... The standard diet-fed animals obtained 7.5 per cent of their calories from fat, while the high fat diet-fed animals obtained 55 per cent of their calories from fat ... According to the data, after only 5 days on the high-fat diet the physical endurance of the rats decreased by 30 per cent, compared to animals on the low-fat diet. By the ninth day, the animals were running 50 per cent less far ... their performance in the maze task also decreased. The number of correct decisions before making a mistake dropped from over six to an average of 5 to 5.5"

Lycopene linked to healthier blood vessels - Nutra USA, 8/13/09 - "Higher levels of lycopene in the blood are associated with lower stiffness in the arteries ... women with the highest average lycopene blood levels (more than 0.0431 millimoles per litre) had the lowest baPWV values, compared to people with the lowest average lycopene blood levels (less that 0.0342 mmol/L) ... According to their results, women with the highest average lycopene blood levels (more than 0.0431 millimoles per litre) had the lowest baPWV values, compared to people with the lowest average lycopene blood levels (less that 0.0342 mmol/L) ... these women also had lower oxidised LDL levels, as well as larger LDL particles ... Levels of C-reactive protein, a marker of inflammation, were also lower in the women with the highest lycopene levels" - See lycopene at Amazon.com.

Abstracts from this week's Doctor's Guide Nutrition/Dietetics plus abstracts from my RSS feeds (Click here for the journals, the PubMed ones at the top):

Prehypertension is associated with insulin resistance - QJM. 2009 Aug 7 - "All subjects received a 75-g oral glucose tolerance test (OGTT) for the measurements of IR ... The prehypertensive subjects were more obese and had higher levels of fasting triglycerides and 2-h insulin than the normotensives. The subjects with prehypertension were more insulin resistant than the counterparts, indicated by lower insulin sensitivity index, ISI(0,120), values. While there was no difference between the two groups in insulin response of OGTT after adjustments for confounders, the prehypertension group maintained significant between-group differences in glucose response even when the incremental insulin levels were added to covariates for adjustments ... Our data show that prehypertension is associated with IR. The subjects with prehypertension have clinical characteristics of the IR syndrome. It seems that the prehypertension group cannot handle oral glucose challenge as well as the normotension, probably a consequence of IR in prehypertension"

Effect of Influenza Vaccination of Nursing Home Staff on Mortality of Residents: A Cluster-Randomized Trial - J Am Geriatr Soc. 2009 Aug 4 - "Influenza vaccine was administered to volunteer staff after a face-to-face interview ... Staff influenza vaccination rates were 69.9% in the vaccination arm versus 31.8% in the control arm. Primary unadjusted analysis did not show significantly lower mortality in residents in the vaccination arm (odds ratio=0.86, P=.08), although multivariate-adjusted analysis showed 20% lower mortality (P=.02), and a strong correlation was observed between staff vaccination coverage and all-cause mortality in residents (correlation coefficient=-0.42, P=.007). In the vaccination arm, significantly lower resident hospitalization rates were not observed, but ILI in residents was 31% lower (P=.007), and sick leave from work in staff was 42% lower" - Note:  I keep hearing people say it's not worth it to get the flu shot.  The way I look at it, the most likely cause of dying from the flu would be being exposed to a virus that is very different than what you've been exposed to in the past.  I feel that the more flu shots you've had in the past, the lower the chances of that happening.  I mentioned before about a virus that I got in Australia that I though would kill me but it's a good  example.  It's got nothing to do with flu shots but it was probably a virus that nearly killed me from neck cancer that may have been prevented by the HPV vaccine.  Something to think about for people foreign things like the flu shot.

Beneficial Effects of Taurine on Cardiac Abnormality in NZB/W F1 Mice Fed with a High-Cholesterol Diet J Agric Food Chem. 2009 Aug 14 - "Improved cardiac histopathological changes were observed in left ventricle tissues from the cholesterol/taurine group as compared to the control or cholesterol group. Significant reductions of TUNEL-positive cells, Fas death receptor-related components, mitochondrial-dependent apoptosis, cardiac fibrosis, and fibrotic signaling components were detected in the left ventricle tissues from the cholesterol/taurine group as compared to the control or cholesterol group. Additionally, cardiac IGR1R survival signaling components were significantly increased in the left ventricle tissues from the cholesterol/taurine group as compared to the control or cholesterol group. These findings revealed the protective effects of taurine against the cardiac abnormalities in NZB/W F1 mice and may suggest the potential for clinical application of taurine in treatment of CVD in SLE" - See taurine at Amazon.com.

Liver Safety in Patients with Type 2 Diabetes Treated with Pioglitazone: Results from a 3-Year, Randomized, Comparator-Controlled Study in the US - Drug Saf. 2009;32(9):787-800 - "No case of hepatic dysfunction or hepatic failure was reported in either treatment group; two cases of hepatic cirrhosis with glibenclamide were reported. This study demonstrates an hepatic safety profile of pioglitazone similar to that of glibenclamide in long-term use in patients with poorly controlled type 2 diabetes"

Vitex agnus-castus (Chaste-Tree/Berry) in the treatment of menopause-related complaints - J Altern Complement Med. 2009 Aug;15(8):853-62 - "We conclude that, while evidence from rigorous randomized controlled trials is lacking for the individual herb in this context, emerging pharmacological evidence supports a role for V. agnus-castus in the alleviation of menopausal symptoms and suggests that further investigation may be appropriate"

Dietary correlates of urinary 6-sulfatoxymelatonin concentrations in the Nurses' Health Study cohorts2 - Am J Clin Nutr. 2009 Aug 12 - "In multivariate analyses, we found no significant associations between the intake of various nutrients, including tryptophan and urinary melatonin concentrations. A higher intake of meat, particularly red meat, was associated with lower concentrations of aMT6s (adjusted mean concentrations of aMT6s across increasing quartiles of red meat intake were 17.9, 17.0, 18.1, and 15.3 ng/mg creatinine; P for trend = 0.02). In contrast, neither intake of poultry (including turkey) nor fish was associated with aMT6s concentrations ... Although no specific nutrients were associated with altered concentrations of melatonin, our findings raise the possibility that several specific foods, including red meat, could affect cancer risk through the lowering of melatonin concentrations"

Chinese tea consumption is associated with longer telomere length in elderly Chinese men - Br J Nutr. 2009 Aug 12:1-7 - "In men, only Chinese tea consumption was significantly associated with TL after adjustment for demographics and lifestyle factors (P = 0.002). Mean difference in TL for those in the highest quartile of Chinese tea consumption (>3 cups/d or >750 ml/d) as compared with those in the lowest quartile of Chinese tea consumption ( </= 0.28 cups/d or </= 70 ml/d) was 0.46 kb, corresponding to approximately a difference of 5 years of life" - See green tea extract at Amazon.com.

Effect of betaine supplementation on power performance and fatigue - J Int Soc Sports Nutr. 2009 Feb 27;6:7 - "Subjects were tested prior to the onset of supplementation (T1) and 7 (T2) and 14 days (T3) following supplementation ... No differences were seen at T2 or T3 in the repetitions performed to exhaustion or in the number of repetitions performed at 90% of both peak and mean power between the groups in the bench press exercise. The number of repetitions performed in the squat exercise for BET was significantly greater (p < 0.05) than that seen for PL at T2. The number of repetitions performed at 90% or greater of peak power in the squat exercise was significantly greater for BET at both T2 and T3 than PL" - See trimethylglycine at Amazon.com.

Resveratrol prevents hyperglycemia-induced endothelial dysfunction via activation of adenosine monophosphate-activated protein kinase - Biochem Biophys Res Commun. 2009 Aug 7 - "Endothelial dysfunction secondary to persistent hyperglycemia plays a key role in the development of type 2 diabetic vascular disease ...

28. Blood Sugar Linked To Normal Cognitive Aging - Science Daily, 12/30/08 - "Beyond the obvious conclusion that preventing late-life disease would benefit the aging hippocampus, our findings suggest that maintaining blood sugar levels, even in the absence of diabetes, could help maintain aspects of cognitive health. More specifically, our findings predict that any intervention that causes a decrease in blood glucose should increase dentate gyrus function and would therefore be cognitively beneficial" - [WebMD]
29. Diabetes Linked To Cognitive Deterioration - Science Daily, 3/5/09 - "people with diabetes were 1.5 more likely to experience cognitive decline, and 1.6 more likely to suffer from dementia than people without diabetes ... suggests that higher-than-average levels of blood glucose (blood sugar) may have a role in this relationship ... in people with type 2 diabetes, higher levels of haemoglobin A1C (a measure of average blood glucose) are significantly associated with poorer performance on three cognitive tasks which require memory, speed and ability to manage multiple tasks at the same time. A higher A1C level was also associated with a lower score on a test of global cognitive function ... lowering A1C levels could slow the accelerated rate of cognitive decline experienced by people with diabetes"

41. Prevention of Type 2 diabetes: fact or fiction? - Expert Opin Pharmacother. 2007 Dec;8(18):3147-58 - "Both studies have shown that intensive lifestyle intervention could reduce the progression of IGT to diabetes by 58%. Furthermore, four currently-available drugs have been established as being effective in preventing diabetes in subjects with prediabetes. The Diabetes Prevention Program revealed that metformin 850 mg b.i.d. reduced the risk of diabetes by 31%. The STOP-NIDDM (Study To Prevent Non-Insulin-Dependent Diabetes Mellitus) trial (n = 1429) showed that acarbose 100 mg t.i.d. with meals decreased the incidence of diabetes by 36% when the diagnosis was based on 2 oral glucose tolerance tests. The XENDOS (Xenical in the Prevention of Diabetes in Obese Subjects) study examined the use of orlistat, an antiobesity drug, as an adjunct to an intensive lifestyle modification program in obese non-diabetic subjects. Orlistat treatment resulted in a 37% decline in the development of diabetes. More recently, the DREAM (Diabetes Reduction Assessment with Ramipril and Rosiglitazone Medication) study (n = 5269) demonstrated that rosiglitazone at 8 mg once/day in subjects with prediabetes (IGT and/or impaired fasting glucose) was effective in reducing the risk of diabetes by 60%. It can be concluded that Type 2 diabetes can be prevented or delayed through lifestyle modifications and/or pharmacologic interventions. This is a fact"

No patient developed heart failure. Both therapies similarly improved glycemic control, whole-body insulin sensitivity, and blood pressure. Pioglitazone versus metformin improved the early peak flow rate (P=0.047) and left ventricular compliance. Pioglitazone versus metformin increased myocardial glucose uptake (P<0.001), but pioglitazone-related diastolic improvement was not associated with changes in myocardial substrate metabolism. Metformin did not affect myocardial function but decreased cardiac work relative to pioglitazone (P=0.006), a change that was paralleled by a reduced myocardial glucose uptake and fatty acid oxidation. Neither treatment affected cardiac high-energy phosphate metabolism or triglyceride content. Only pioglitazone reduced hepatic triglyceride content" - I still take pioglitazone even though I don't have diabetes because I feel that higher glucose levels are a major cause of aging.  There doesn't seem to be any evidence that it has the heart rises that rosiglitazone has.  See Pioglitazone at OffshoreRx1.com.
