Abstract

Keywords:  Intrahepatic cholestasisLymphoedemaNutrition assessmentNutrient intakeSyndrome
BACKGROUND & AIMS: Patients with lymphoedema cholestasis syndrome 1/Aagenaes Syndrome need a fat reduced diet when cholestatic. We wanted to assess the need for dietary counselling outside cholestatic episodes, and hypothetized that no counselling was needed.

METHODS:

Fifteen patients above 10 years of age without symptoms of cholestasis were compared with a sex and age matched control group. Diet from a four-day weighed record and blood samples were compared between the two groups and with general Norwegian recommendations.

RESULTS:

The patients had a similar diet to the healthy controls, except for statistically significant lower intake of energy from total fat (p=0.04) and saturated fat (0.02), and fish (0.05). The patients met the dietary recommendations for macronutrients, except for saturated fat, monounsaturated fat, refined sugar and fibre. Supplements were needed to meet the micronutrient recommendations. Patients had a significantly lower serum level of alpha-tocopherol (0.01) compared with the control group, and the serum 25-OH D level was below reference ranges.

CONCLUSIONS:

The patients would benefit from counselling on fat quality, carbohydrates including fibre intake, and individual needs for vitamins D and E. To secure serum 25-OH D and alpha-tocopherol levels within reference ranges, regular examinations to determine the need for supplementary vitamins D and E are recommended.

Abstract

Vegetarians are at risk for vitamin B(12) (B12) deficiency due to suboptimal intake. The goal of the present literature review was to assess the rate of B12 depletion and deficiency among vegetarians and vegans. Using a PubMed search to identify relevant publications, 18 articles were found that reported B12 deficiency rates from studies that identified deficiency by measuring methylmalonic acid, holo-transcobalamin II, or both. The deficiency rates reported for specific populations were as follows: 62% among pregnant women, between 25% and almost 86% among children, 21-41% among adolescents, and 11-90% among the elderly. Higher rates of deficiency were reported among vegans compared with vegetarians and among individuals who had adhered to a vegetarian diet since birth compared with those who had adopted such a diet later in life. The main finding of this review is that vegetarians develop B12 depletion or deficiency regardless of demographic characteristics, place of residency, age, or type of vegetarian diet. Vegetarians should thus take preventive measures to ensure adequate intake of this vitamin, including regular consumption of supplements containing B12.

Abstract

In the year 2011, 6.9 million children under the age of 5 years died worldwide, one third of them related to increased susceptibility to illnesses due to under nutrition. An estimated 178 million children under 5 years are stunted, 55 million are wasted, and 19 million of these are severely affected and are at a higher risk of premature death, the vast majority being from sub-Saharan Africa and South-Central Asia. Globally, over 2 billion people are at risk for vitamin A, iodine, and/or irondeficiency. Other micronutrient deficiencies of public health concern include zinc, folate, and the B vitamins. 
The risk factors for undernutrition include low birth weight, inadequate breastfeeding, improper complementary feeding, and recurrent infections. Infectious diseases often coexist with micronutrient deficiencies and exhibit complex interactions leading to the vicious cycle of malnutrition and infections. Diarrhea along with the poor selection and intake of complementary food are the major contributors to undernutrition. 
Possible strategies to combat malnutrition include promotion of breastfeeding, dietary supplementation of micronutrients, prevention of protein-energy malnutrition, and improvement in the standard of preparation and hygiene of available weaning foods. The universal coverage with the full package of these proven interventions at observed levels of program effectiveness could prevent about one quarter of child deaths under 36 months of age and reduce the prevalence of stunting at 36 months by about one third. 

The median coverage rate of interventions along the continuum of care for Countdown countries has however beenlesws then 80 percent for vaccination and vitamin A supplementation. However, for several interventions, including early initiation and exclusive breastfeeding below 6 months of age and case management of childhood illnesses, the median coverage rate hovers at or below fifty percent. This suggests that interventions requiring strong health systems or behavior change appear to be stalled and need to be re-examined to find more effective ways of delivery.

Cranberry Proanthocyanidins Improve Intestinal sIgA During Elemental Enteral Nutrition.


Cranberry Proanthocyanidins Improve Intestinal sIgA During Elemental Enteral Nutrition.

Abstract


Background: 
Elemental enteral nutrition (EEN) decreases gut-associated lymphoid tissue (GALT) function, including fewer Peyer's patch lymphocytes and lower levels of the tissue T helper 2 (Th2) cytokines and mucosal transport protein polymeric immunoglobulin receptor (pIgR), leading to lower luminal secretory immunoglobulin A (sIgA) levels. Since we recently demonstrated that cranberry proanthocyanidins (PACs) maintain the Th2 cytokine interleukin (IL)-4 when added to EEN, we hypothesized the addition of PACs to EEN would normalize other GALT parameters and maintain luminal levels of sIgA. 

Methods
Institute of Cancer Research mice were randomized (12/group) to receive chow, EEN, or EEN + PACs (100 mg/kg body weight) for 5 days, starting 2 days after intragastric cannulation. Ileum tissue was collected to measure IL-4 by enzyme-linked immunosorbent assay, pIgR by Western blot, and phosphorylated STAT-6 by microarray. Intestinal wash fluid was collected to measure sIgA by Western blot. 

Results: 
Compared with chow, EEN significantly decreased tissue IL-4, phosphorylated STAT-6, and pIgR. The addition of PACs to EEN prevented these alterations. Compared with chow, EEN resulted in significantly lower levels of luminal sIgA. The addition of PACs to EEN increased luminal sIgA levels compared with EEN alone. 

Conclusions: 
This study suggests the addition of PACs to EEN may support GALT function and maintain intestinal sIgA levels compared with EEN administration alone

Abstract


Depression is a debilitating disorder estimated to become the second cause of morbidity worldwide by the year 2020. The limited efficacy of antidepressant therapy, as well as the major negative consequences of this disorder, has stimulated additional research in order to determine possible adjunctive treatments. There is mounting evidence linking dietary patterns to major depression development. This article presents some of the most significant findings concerning the role of nutrition in major depressive disorder. Although more focused and clear results are needed, the correlation between nutrition and mental health is gaining attention. Now, there is evidence supporting the importance of nutrition in maintaining good mental health. We emphasize multiple findings that support adherence to healthy dietary patterns, taking into account that the production of neurotransmitters need, among others, right amounts of nutrients, a lot of which can only be supplied through diet. Not only certain nutrients are needed for proper brain functioning, but also others can be harmful, promoting depression. The Mediterranean diet has been linked to a low prevalence of depression while fast-food consumption has been found to increase the risk of developing and aggravating this disorder, hence the need for nutritional interventions. From the perspective of discovering modifiable risk factors, the role of nutrition in psychiatry could be more important than it was initially considered.

Vitamins can harm cancer patients: scientist


Vitamins can harm cancer patients: scientist

Jan 2013

LATE-stage cancer patients could be thwarting their own treatment by taking multi-vitamin pills containing antioxidants, the Nobel Prize-winning scientist James Watson has warned.

The benefits of supplements containing antioxidants such as vitamins A, C and E are the subject of fierce debate.

While some studies suggest that they could offer moderate protection against cancer, Professor Watson, who with Francis Crick discovered the ''double helix'' structure of DNA in 1953, argues that the pills could be doing more harm than good.

In a new paper, he claims that the reason late-stage cancers often become untreatable is that they produce high levels of antioxidants which stop treatments such as chemotherapy and radiotherapy from working.In healthy people, antioxidants can be helpful because they attack molecules known as ''free radicals'' which can damage DNA. But many cancer treatments use free radicals to kill tumour cells, meaning antioxidants could prevent them doing their job.

Professor Watson said studies should be carried out to test his theory, which he described as ''among my most important work since the double helix''.

Writing in the Royal Society's Open Biology journal, he said: ''For as long as I have been focused on the understanding and curing [of] cancer, well-intentioned individuals have been consuming antioxidative nutritional supplements as cancer preventatives if not actual therapies.

''In light of the recent data strongly hinting that much of late-stage cancer's untreatability may arise from its possession of too many antioxidants, the time has come to seriously ask whether antioxidant use much more likely causes, than prevents, cancer.

''Blueberries [which are high in antioxidants] had best be eaten because they taste good, not because their consumption will lead to less cancer.''

Professor Nic Jones, Cancer Research UK's chief scientist, said: ''We know from many large studies that, far from being potent cancer-fighters, antioxidant supplements seem to be ineffective for cancer prevention in healthy people, and some can even slightly increase the risk of cancer. This should give people good reason to think twice about relying on them.''
Steve Williamson, cancer spokesman for Britain's Royal Pharmaceutical Society, added: ''I always advise patients not to take antioxidants while they are having chemotherapy in case it counteracts it.''

Cancer Council Australia's chief executive Ian Olver said the comments ''had merit''.
''Multi-vitamins are something that may be helpful in prevention, but they may not be helpful for treatment,'' Professor Olver said.

With a study last year showing that more than 50 per cent of male cancer patients in Australia were using ''complementary and alternative medicines'' while receiving chemotherapy or radiotherapy, Professor Olver said patients and doctors should ensure that alternative medicine use is out in the open.
