Teen pot use could hurt brain and memory, new research suggests - NBC
News.com, 12/16/13 - "Research released Monday in the
journal Schizophrenia Bulletin showed the brains of young heavy marijuana users
were altered in so-called sub-cortical regions — primitive structures that are
part of the memory and reasoning circuits. And young people with such
alterations performed worse on memory tests than non-using controls, despite the
fact that the heavy users had not indulged for more than two years, on average,
before the testing"
Should Patients Taking
Metformin Also Take Vitamin B12? - Medscape, 12/13/13 -
"Vitamin B12
deficiency is estimated to be present in up to 30% of patients with diabetes
taking metformin.[1] The risk for vitamin B12
deficiency increases with patient age and the dose and duration of metformin
use.[5,7] Concomitant conditions such as suboptimal dietary intake, which is
common among vegetarians and alcohol abusers, and malabsorption due to atrophic
gastritis, pernicious anemia, chronic pancreatitis, and celiac disease may
further increase risk for vitamin B12 deficiency.[5] The combination of
metformin with proton pump inhibitors has been reported to have an additive
effect on risk for vitamin B12 deficiency ... Screening for vitamin B12
deficiency seems reasonable for all adult patients with diabetes, especially
those taking metformin" - See

Open
Access Article on Biological Effects of the Popular Artificial Sweetener
Sucralose - Science Daily, 12/12/13 - "Some of the
biological effects of sucralose
described by Schiffman and Rother include: alterations in insulin, blood
glucose, and glucagon-like peptide 1 (GLP-1) levels, metabolism of sucralose in
the gastrointestinal tract to metabolites whose identity and safety profile are
unknown, induction of cyctochrome P450 and P-glycoprotein in the
gastrointestinal tract to levels that may limit the bioavailability of
therapeutic drugs, reduction in the number and balance of beneficial bacteria in
the gastrointestinal tract, histopathological findings in gastrointestinal tract
including lymphocytic infiltrates into epithelium, epithelial scarring, mild
depletion of goblet cells and glandular disorganization in the colon,
decomposition and generation of chloropropanols (a potentially toxic class of
compounds) during baking, and mutagenic alterations using several types of
biological assays"

Dietary
amino acids improve sleep problems in mice with traumatic brain injury -
Science Daily, 12/11/13 - "the scientists gave the
injured mice a dietary therapy of branched chain amino
acids -- which humans get most often through foods high in protein,
including red meat, poultry and eggs. Branched chain amino acids are the
building blocks of neurotransmitters, the chemicals released by neurons in the
brain. Like the oil in a car engine, branched chain amino acids keep neurons
running smoothly and boost neuron excitability. The branched chain amino acids
restored the orexin neurons in the injured mice to a normal activity level, and
improved wakefulness ... If a dietary supplement can
improve sleeping and waking patterns as well as cognitive problems, it could
help brain-injured patients regain crucial functions ... human patients with a
variety of disorders have been treated with branched chain amino acid therapy
for up to two years without adverse effects" - See

Low
vitamin B12 levels increase risk of fractures in older men - Science Daily,
12/10/13 - "the Gothenburg researchers studied 1,000
Swedish men, MrOS Sweden, with an average age of 75, and used various methods to
analyze the blood concentrations of the B vitamins
B12 and folate, which are found in our food naturally ... the risk of
suffering a fracture six years later was
higher among men who had low B12 levels at the beginning of the study than men
with normal B12 levels. In the quartile with the lowest B12 content, the risk
was elevated by approximately 70 percent compared with the others. The risk
increase pertained primarily to fractures in the lumbar region, where the risk
increase was up to 120 percent" - See

Calcium + Vitamin D:
Surprises From Long-term Follow-up - Medscape, 12/11/13 -
"the analyses that were limited to adherent women who
were taking at least 80% of their study pills compared with the women who were
taking at least 80% of their placebo pills showed a statistically significant
29% reduction in the risk for hip fracture
... Also shown in the new report is that with longer-term follow-up, a
statistically significant reduction in in situ breast
cancer emerged -- a 13% reduction overall ... In terms of
all cancers, among the women who had low baseline
intake of vitamin D, there was a statistically
significant 9% reduction in total cancer with supplementation, and also a
marginally significant 9% reduction in all-cause
mortality" - See

The microbes in your gut may be making you fat or keeping you thin - The
Washington Post, 12/6/13 - "naturally occurring bacteria
and other microbes in the body, and possibly even viruses, can influence weight
in ways that scientists are only just beginning to understand ... Studies in
mice have shown that intestinal microbes may
contribute to weight gain. A novel
experiment published this fall, for example, took gut bacteria from human twins
— in which one was lean and the other obese — and transferred them into lean
mice. The animals with bacteria from fat twins grew fat; those that received
bacteria from lean twins stayed lean" - See

BPA is still everywhere, and mounting evidence suggests harmful effects -
The Washington Post, 12/6/13 - "the chemical is found in
many other common items: medical devices, dental sealants and compact discs, to
name a few. Even paper receipts from the grocery store and ATM machines often
contain BPA. In short, it’s pretty hard to avoid the chemical ... When chemicals
such as BPA mimic hormones, it leads to what’s called
endocrine disruption ... BPA has also been linked to obesity and Type 2 diabetes
... Researchers have also found that newborn rats that were exposed to low doses
of BPA for a short period had a significantly higher risk of prostate cancer (an
estrogen-induced cancer) later in life ... low-level exposure to BPA in pregnant
mice suppresses gene expression of two proteins that are important in regulating
social behavior — oxytocin and vasopressin — and alters social behaviors in the
fourth generation ... We can reduce our BPA exposure by making choices such as
opting for electronic receipts, using fresh and frozen vegetables rather than
canned, choosing glass and stainless steel containers and not microwaving food
in polycarbonate plastic containers"
Long-term use of common heartburn and ulcer medications linked to vitamin B12
deficiency - Science Daily, 12/10/13 - "Left
untreated, vitamin B12 deficiency can increase
the risk of dementia, nerve damage, anemia, and other medical complications,
some of which may be irreversible. Stomach acid aids in vitamin B12 absorption;
suppressing the acids can lead to the health-threatening vitamin deficiency ...
Researchers examined the electronic health records (including diagnoses,
pharmacy orders, and laboratory results) of 25,956 adult Kaiser Permanente
patients diagnosed with vitamin B12 deficiency in Northern California between
January 1997 and June 2011 ... Patients who took PPI medications for more than
two years had a 65 percent increase in their risk of B12 deficiency"

The
Protective Role of Resveratrol against Arsenic Trioxide-Induced Cardiotoxicity
- Evid Based Complement Alternat Med. 2013;2013:407839 -
"Arsenic trioxide (As2O3) shows substantial
anticancer activity in patients with acute promyelocytic
leukemia (APL). Unfortunately, limiting the
application of this effective agent to APL patients is severe cardiotoxicity.
Resveratrol, the natural food-derived
polyphenolic compound, is well known for its antioxidant properties and protects
the cardiovascular system. But the potential role of resveratrol against As2O3
in heart via nuclear factor erythroid 2-related factor 2 (Nrf2) and heme
oxygenase-1 (HO-1) is unclear ... Our findings suggest coadministration with
resveratrol, and As2O3 might provide a novel therapeutic strategy for APL"

Significance
of Imbalance in the Ratio of Serum n-3 to n-6 Polyunsaturated Fatty Acids in
Patients With Acute Coronary Syndrome - Am J Cardiol. 2013 Nov 7 -
"We enrolled 1,119 patients who were treated and in whom
serum PUFA level was evaluated in 5 divisions of cardiology in a metropolitan
area in Japan ... eicosapentaenoic acid (EPA),
docosahexaenoic acid (DHA), and
arachidonic acid (AA) ... According
to multivariate logistic regression analysis, the group with the lowest EPA/AA
(≤0.33) had a greater probability of ACS (odds ratio 3.14, 95% confidence
interval 1.16 to 8.49), but this was not true for DHA/AA. In conclusion, an
imbalance in the ratio of serum EPA to AA, but not in the ratio of DHA to AA,
was significantly associated with ACS"

Serum levels of vitamin E
forms and risk of cognitive impairment in a Finnish cohort of older adults
- Exp Gerontol. 2013 Dec;48(12):1428-35 - "A sample of
140 non-cognitively impaired elderly subjects derived from the Cardiovascular
Risk Factors, Aging, and Dementia (CAIDE) study was followed-up for 8years to
detect cognitive impairment, defined as development of mild cognitive impairment
(MCI) or Alzheimer's dementia. The association between baseline serum
vitamin E and
cognitive impairment was analyzed with multiple
logistic regression after adjusting for several confounders ... Elevated levels
of tocopherol and tocotrienol forms are associated with reduced risk of
cognitive impairment in older adults. The association is modulated by concurrent
cholesterol concentration. Various vitamin E forms might play a role in
cognitive impairment, and their evaluation can provide a more accurate measure
of vitamin E status in humans" - [Nutra

Lower
lifetime dietary fiber intake is associated with carotid artery stiffness: the
Amsterdam Growth and Health Longitudinal Study - Am J Clin Nutr. 2012
Jul;96(1):14-23 - "This was a longitudinal cohort study
among 373 participants in whom dietary intake was assessed between the ages of
13 to 36 y (2-8 repeated measures, median of 5), and arterial stiffness
estimates of 3 large arteries (ultrasonography) were ascertained at age 36 y ...
After adjustment for sex, height, total energy intake, and other lifestyle
variables, subjects with stiffer carotid arteries consumed less fiber (in g/d)
during the 24-y study than did those with less stiff carotid arteries, as
defined on the basis of the highest compared with the lowest sex-specific
tertiles of the distensibility and compliance coefficients (reversed) and
Young's elastic modulus: -1.9 (95% CI: -3.1, -0.7), -2.3 (-3.5, -1.1), and -1.3
(-2.5, -0.0), respectively. Furthermore, subjects with stiffer carotid arteries
were characterized by a lower lifetime consumption of fruit, vegetables, and
whole grains-deleterious associations that could be explained, to a great
extent, by related low fiber intake"

Amazing acai alleviates atherosclerosis: Study - Nutra USA, 4/6/11 -
"The study, published in Atherosclerosis , presents
evidence to suggest that the athero-protective effect of the açaí juice is in

oxidative stress were found to be significantly lower in the serum and liver of
açaí juice fed animals ... Results from analysis of 17 genes related to
oxidation/antioxidant enzymes also showed that expression of two antioxidant
enzyme genes glutathione peroxidase (GPX) and glutathione reductase (GSR) –
considered important antioxidant enzymes in vascular systems – were
significantly up-regulated in the aorta of açaí juice fed mice ... The
activities of GSR in serum and liver and GPX in serum were also reported to
increase in açaí juice fed mice ... Hence, these two antioxidant enzymes may act

Biomarkers of lipid peroxidation, including F(2)-isoprostanes and isomers of
hydroxyoctadecadienoic acids and hydroxyeicosatetraenoic acids were
significantly lower in serum and in liver of AJ fed mice. Expression of the two
antioxidant enzyme genes, Gpx3 and Gsr, were significantly up-regulated in the

Protective
effects of dehydroepiandrosterone on atherosclerosis in ovariectomized rabbits
via alleviating inflammatory injury in endothelial cells - Atherosclerosis.
2010 Aug 3 - "The risk for atherosclerosis is increased
in postmenopausal women. Dehydroepiandrosterone (DHEA) is postulated to have
anti-atherogenic properties ... DHEA administration alleviates efficiently the
early pathologic damage of atherosclerosis, increases the serum NO level, and
up-regulates the endothelial cell estrogen receptor (ER) expression of
ovariectomized rabbits. DHEA in vitro significantly promotes NO synthesis,
suppresses MDA and MCP-1 secretion of endothelial cells, and decreases ICAM-1,
VCAM-1 and E-selectin expression in HUVECs; neither selective ERα antagonist
(methyl-piperidino-pyrazole, MPP) nor ERβ antagonist (R,R-tetrahydrochrysene,
R,RTHC) can abolish these effects. Furthermore, DHEA reduces CCR2, LFA-1 and
VLA-4 expression in U937 cells, which in turn inhibits the adherence of
monocytes to the injured endothelial cells. DHEA significantly decreased the
LPS-induced NF-κB transcription" - See

Effects
of acetyl-L-carnitine and oxfenicine on aorta stiffness in diabetic rats
- Eur J Clin Invest. 2010 Jul 29 - "Oxfenicine, but
not acetyl-L-carnitine, increased total peripheral resistance in diabetes,
which paralleled its elevation in plasma levels of free fatty acids. By
contrast, acetyl-L-carnitine, but not oxfenicine, resulted in a significant
increase in wave transit time and a decrease in wave reflection factor,
suggesting that acetyl-L-carnitine may attenuate the diabetes-induced
deterioration in systolic loading condition for the left ventricle. This was
in parallel with its lowering of MDA/TBARS content in plasma and aortic
walls in diabetes. Acetyl-L-carnitine therapy also prevented the
diabetes-related cardiac hypertrophy, as evidenced by the reduction in ratio
of the left ventricular weight to body weight. Conclusion
Acetyl-L-carnitine, but not oxfenicine, attenuates aortic stiffening and
cardiac hypertrophy, possibly through its decrease of lipid
oxidation-derived MDA/TBARS in the rats with insulin deficiency" -

Low Vitamin D Raises Heart Disease Risks In Diabetics - Science Daily,
8/21/09 - "Low levels of vitamin D are known to
nearly double the risk of cardiovascular disease in patients with diabetes

cholesterol, and they can't get rid of it. The macrophages get clogged with
cholesterol and become what scientists call foam cells, which are one of the
earliest markers of atherosclerosis" - See

Resveratrol inhibits the mTOR mitogenic signaling evoked by oxidized LDL in
smooth muscle cells - Atherosclerosis. 2008 Nov 24 -
"Smooth muscle cell (SMC) proliferation is a major
feature in atherosclerosis, since it contributes to the formation of the
fibrous cap, thus to plaque stability, but also to arterial stenosis and
post-angioplasty restenosis ... These data indicate that the mTOR pathway is
activated by oxLDL via PI3K/PDK1/Akt, and is required for SMC proliferation.
Resveratrol blocks specifically this pathway, thereby inhibiting
oxLDL-induced SMC proliferation. These data highlight a new property for
resveratrol that could contribute to the general anti-atherogenic properties

there is a defect in the resolution response -- the ability of blood vessels
to recover from inflammation -- atherosclerosis or hardening of the arteries
can result ... Some natural mediators that 'cool' this inflammation are

HbA1c
Levels Predict Carotid IMT in Diabetic Adolescents - Medscape, 11/13/09 -
"For every 1% increase in HbA1c, the likelihood of
having a thicker common carotid IMT increased by 35%, after adjustment for sex,
systolic blood pressure z-score, and insulin use ... These data suggest that
poor glycemic control is associated with structural changes in the carotid
artery that are consistent with early atherosclerosis"

HbA1c is
associated with intima media thickness in individuals with normal glucose
tolerance - Diabetes Care. 2009 Oct 6 - "normal
glucose tolerant individuals (NGT) ... 1h-glucose and
HbA1c were significantly correlated to carotid IMT in individuals with NGT,
while fasting and 2h-glucose were not informative. Only HbA1c was associated
with IMT independent of other confounders, while 1h-glucose was not informative
... HbA1c was the most informative glycemic marker with respect to IMT in
individuals with NGT"

Stress Raises Belly Fat, Heart Risks - WebMD, 8/6/09 -
"Even compared to other monkeys with the same body mass
index and weight, CT scans showed that the stressed monkeys had a great deal
more belly fat. And when the researchers looked at the animals' arteries, they
found plaque clogging the arteries of the stressed monkeys ... it's not how much
fat you have, but where it is located ... Over time, high cortisol levels cause
belly fat to accumulate. It also makes individual fat cells get larger ... When
you have lots more fat in visceral fat cells and all the characteristics of the
metabolic syndrome, each of these things promotes atherosclerosis"

which is a measure of diurnal cortisol decline. Results: Total cortisol exposure
while awake (AUC) was associated with higher plaque scores (beta = 0.08 per SD
of AUC, 95% CI; 0.00 - 0.17, p-value = 0.04) in a fully adjusted linear
regression model. Persons with an AUC in the highest tertile had a higher number
of plaques of carotid arteries compared to those in the lowest tertile (3.08

Pioglitazone May Prevent Progression of Atherosclerosis in Patients With
Type 2 Diabetes - Doctor's Guide, 4/2/08 - "Two
TZD agents are currently on the market -- pioglitazone and rosiglitazone.
Both agents reduce inflammatory biomarkers, while pioglitazone also produces
elevation of high-density lipoprotein cholesterol (HDL-C) and reduction of
triglyceride levels ... Dr. Nissen said the findings of the PERISCOPE study
support the conclusion that treatment with pioglitazone can prevent the
progression of atherosclerosis in patients with type 2 diabetes during 18
months of treatment. These finding may have important implications for
defining the optimal strategy for management of patients with type 2
diabetes and coronary atherosclerosis" - See pioglitazone at
