A Narrative Review of Complementary Nutritional Supplements for Chemotherapy-induced Peripheral Neuropathy.
Conclusion: Nutritional therapists seem to recommend nutrient supplements as potential anti-inflammatory and neuroprotective agents for both the prevention and management of CIPN. An understanding of this evolving literature is useful in exploring these therapies with patients who are considering using them. However, their effects against CIPN are still controversial due to the undetermined neuropathic mechanisms of different antineoplastic agents and complex drug interactions. Further research on these agents is warranted. PMID: 31634876 [PubMed - as supplied by publisher] (Source: Alternative Therapies in Health and Medicine)

Tryptophan catabolites as metabolic markers of vitamin B-6 status evaluated in cohorts of healthy adults and cardiovascular patients.
This study aimed to comprehensively evaluate the use of Kyns as potential markers of functional vitamin B-6 status across 2 large cohorts. METHODS: We measured circulating concentrations of the first 6 metabolites in the Trp catabolic pathway by LC-MS-MS in the community-based Hordaland Health Study (HUSK; n = 7017) and cardiovascular patient-based Western Norway Coronary Angiography Cohort (WECAC; n = 4161). Cross-sectional and longitudinal associations of plasma PLP with Kyns were estimated using linear and nonlinear regression-based methods. RESULTS: 3'-Hydroxykynurenine (HK), a subst...

Preoperative Gabapentin Administration Improves Acute Postoperative Analgesia in Patients Undergoing Craniotomy: A Randomized Controlled Trial
Background: Gabapentin is an adjuvant antiepileptic agent and helps to reduce acute postoperative pain in several surgery settings. However, the effect of gabapentin on postoperative pain from suboccipital or subtemporal craniotomy is not clear. Methods: The study was a single-center, randomized, placebo-controlled, and double-blinded trial. A total of 122 patients undergoing elective craniotomy by a suboccipital or subtemporal approach were randomly allocated to a placebo group and gabapentin group. The patients received gabapentin (600 mg, orally) the night before surgery and 2 hours before anesthesia inducti...

Sex-Specific Linkages Between Taxonomic and Functional Profiles of Tick Gut Microbiomes
Ticks transmit the most diverse array of disease agents and harbor one of the most diverse microbial communities. Major progress has been made in the characterization of the taxonomic profiles of tick microbiota. However, the functional profiles of tick microbiome have been comparatively less studied. In this proof of concept we used state-of-the-art functional metagenomics analytical tools to explore previously reported datasets of bacteria found in male and female Ixodes ovatus, Ixodes persulcatus and Amblyomma variegatum. Results showed that both taxonomic and functional profiles have differences between sexes of the sa...

Genetics of hyperhomocysteinemia and 1-carbon metabolism: implications for retinal structure and eye functions.
Abstract Homocysteine (Hcy); a sulfur-containing non-proteinogenic amino acid is generated as a metabolic intermediate. Hcy constitutes an important part of the "1-carbon metabolism" during methionine turnover. Elevated levels of Hcy known as hyperhomocysteinemia (HHcy) results from vitamin B deficiency, lack of exercise, smoking, excessive alcohol intake, high fat and methionine rich diet, and the underlying genetic defects. These factors directly affect the "1-carbon metabolism (methionine-Hcy-folate)" of a given cell. In fact, the Hcy levels are determined primarily by dietary intake, vitami...

The Critical Role of Nutrition in Facial Plastic Surgery.
er AJ Abstract Nutrition plays a key role in optimizing healing following surgery. The increased catabolic state postoperatively, coupled with a propensity for patients to be suffering from marginal nutritional deficiencies at baseline preoperatively, necessitates that the surgeon be attuned to the need for optimal perioperative nutritional support. This ensures the smoothest recovery and best possible outcomes in facial plastic surgery. Key nutrients include vitamin A, vitamin C, zinc, bromelain, arnica montana, arginine, glutamine, hydrolyzed collagen, vitamin B complex, and protein. The ability for patients to ...

Effect of Vitamin B Supplementation on Cognitive Function in the Elderly: A Systematic Review and Meta-Analysis
ConclusionsRaised total plasma homocysteine is associated with an increased risk of cognitive impairment and dementia, although available evidence from randomized controlled trials shows no obvious cognitive benefit of lowering homocysteine using B vitamins. Existing trials vary greatly in the type of supplementation, population sampled, study quality, and duration of treatment, thereby making it difficult to draw firm conclusions from existing data. Findings should therefore be viewed in the context of the limitations of the available data and the lack of evidence of effect should not necessarily be interpreted as evidenc...

Synergistic Effects of Combined Chlorine and Vitamin B 1 on the Reduction of Murine Norovirus-1 on the Oyster ( Crassostrea gigas ) Surface
This study investigated the synergistic effects of combined chlorine (200, 500, 700, and 1000 ppm) and vitamin B1 (1000, 2000, and 3000 ppm) on the murine norovirus-1 (MNV-1), a human norovirus (NoV) surrogate, on oyster surface. Vitamin B1 slightly reduced MNV-1 (0.04 –0.3 log-reduction), whereas chlorine significantly reduced MNV-1 (0.4–1.0 log-reduction). The combined chlorine and vitamin B1 resulted in a 0.52 –1.97 log-reduction of MNV-1.

Folate/Vitamin B Alleviates Hyperhomocysteinemia-Induced Alzheimer-Like Pathologies in Rat Retina
AbstractHyperhomocysteinemia (Hhcy) is an independent risk factor for Alzheimer ’s disease (AD). Visual dysfunction is commonly found and is positively correlated with the severity of cognitive defects in AD patients. Our previous study demonstrated that Hhcy induces memory deficits with AD-like tau and amyloid-β (Aβ) pathologies in the hippocampus, and supplementation with folate and vitamin B12 (FB) prevents the Hhcy-induced AD-like pathologies in the hippocampus. Here, we investigated whether Hhcy also induces AD-like pathologies in the retina and the effects of FB. An Hhcy rat model was produced by vena...

Vitamin B-12 and liver activity and expression of methionine synthase are decreased in fetuses with neural tube defects.
CONCLUSIONS: The decreased vitamin B-12 in liver and cord blood and decreased expression and activity of MS in liver point out the impaired remethylation pathway as hallmarks associated with NTD risk. We suggest evaluating vitamin B-12 in the nutritional recommendations for prevention of NTD risk beside folate fortification or supplementation.
