Abstract
OBJECTIVES To investigate the effect of a medical food (Souvenaid) on body mass index (BMI) and functional abilities in patients with mild Alzheimer's disease (AD). DESIGN/SETTING/PARTICIPANTS/INTERVENTION /MEASUREMENTS: These analyses were performed on data from a 12-week, double-blind, randomized, controlled, multicenter, proof-of-concept study with a similarly designed and exploratory 12-week extension period. Patients with mild AD (Mini-Mental State Examination score of 20-26) were randomized to receive either the active product or an iso-caloric control product. While primary outcomes included measures of cognition, the 23-item Alzheimer's Disease Cooperative Study-Activities of Daily Living (ADCS-ADL) scale was included as a secondary outcome. Both ADCS-ADL and BMI were assessed at baseline and Weeks 6, 12 and 24. Data were analyzed using a repeated-measures mixed model. RESULTS Overall, data suggested an increased BMI in the active versus the control group at Week 24 (ITT: p = 0.07; PP: p = 0.03), but no treatment effect on ADCS-ADL was observed. However, baseline BMI was found to be a significant treatment effect modifier (ITT: p = 0.04; PP: p = 0.05), and an increase in ADCS-ADL was observed at Week 12 in patients with a 'low' baseline BMI (ITT: p = 0.02; PP: p = 0.04). CONCLUSIONS These data indicate that baseline BMI significantly impacts the effect of Souvenaid on functional abilities. In addition, there was a suggestion that Souvenaid increased BMI.

Abstract
AIM The aim of the present study was to determine if micronutrients supplementation can improve neuropathy indices in type 2 diabetes. MATERIALS AND METHODS In this randomized, double-blind, placebo-controlled clinical trial, 75 type 2 diabetes patients were assigned to three treatment groups, receiving one of the following daily supplement for 4 months: Group MV: zinc (20 mg), magnesium (250 mg), vitamin C (200 mg) and E (100 mg); Group MVB: both of the above mineral and vitamin supplements plus vitamin B1 (10 mg), B2 (10 mg), B6 (10 mg), biotin (200 μg), B12 (10 μg) and folic acid (1 mg); Group P: placebo. RESULTS 67 patients completed the study. Neuropathic symptoms based on the MNSI questionnaire improved from 3.45 to 0.64 (p=0.001) in group MVB, from 3.96 to 1.0 (p=0.001) in group MV and from 2.54 to 1.95 in placebo group after 4 months. There was no significant difference between three treatment groups in MNSI examinations after 4 months supplementations. Over 4 months of treatment, patients showed no significant changes in glycemic control, capillary blood flow or electrophysiological measures in MV and MVB groups compared with placebo group. CONCLUSIONS These studies suggest that micronutrients supplementation might ameliorate diabetic neuropathy symptoms.

Abstract
BACKGROUND Nutritional approach to the deterioration of bone integrity and increased fracture risk appears to be particularly appropriate in elderly women living in nursing homes. OBJECTIVE To investigate the beneficial effect of the consumption of soft plain cheese on bone resorption markers in institutionalized elderly women. DESIGN Prospective, randomized crossover controlled study. SETTING Six French nursing homes or other institutions for elderly. PARTICIPANTS Institutionalized women ≥ 65 years old with low vitamin D status and calcium intake below 700 mg/day. INTERVENTION Consumption of soft plain cheese made of semi-skimmed milk which was fortified by both vitamin D3 (+1.25 µg/100g) and milk extracted Ca, thus achieving a total Ca content of 151 mg/100g as compared to about 118 mg/100g for standard fresh cheese. Two servings were taken every day during the 6 weeks that preceded or followed a period of 6 weeks without soft plain cheese consumption. MEASUREMENTS The primary end point was the change in serum carboxy terminal cross-linked telopeptide of type I collagen (CTX) selected as a marker of bone resorption. RESULTS 29 women aged 73-94 yr were selected, 21 of them with mean age 87.2±6.1 years remained compliant. The intervention increased calcium and protein intakes by 51% (904±228 vs. 599±122 mg/d) and 33 % (74.2±17.1 vs. 55.6±12.7 g/d, mean±SD), respectively. The dietary intervention was associated with a statistically significant increase in serum levels of both 25OHD and IGF-I, while those of [corrected] CTX and TRAP5b were significantly reduced. Compliance was 93,4 %. The daily consumption of two servings of soft plain cheese was well accepted in terms of tastiness and appetite suited portion size. CONCLUSION This randomized crossover controlled trial demonstrates that in elderly women living in nursing homes, the consumption of soft plain cheese increasing the supply of vitamin D, calcium and proteins, could reduce bone resorption and thereby reduce the risk of incidental fragility fractures in the long term.

Abstract
PURPOSE OF REVIEW Childhood malnutrition is prevalent in developing countries and contributes to one-third of all deaths in these countries. There have been advances in prevention of childhood malnutrition and the purpose of this article was to review the current evidence in the field. RECENT FINDINGS Multiple micronutrient (MMN) supplements during pregnancy reduce the incidence of maternal anemia and small for gestational-age babies. Recent evidence suggest that combined supplementation of MMNs with protein energy supplement is more effective than MMN supplementation alone. It is now recommended that HIV-infected mothers can exclusively breast-feed their infants for 6 months when the mother or infant is on effective antiretroviral therapy. Home fortification of complementary foods reduces the prevalence of anemia in infancy and combined supplementation of MMNs with lipid-based supplements improves growth in young children. Ready-to-use therapeutic foods have been successfully used to manage severe acute malnutrition in the community. Zinc supplementation is associated with a reduction in diarrhea and respiratory disease morbidity and improves linear growth. Vitamin A supplementation decreases the incidence of diarrhea and measles. Water supply, sanitation, and hygiene are important for the prevention of malnutrition because of their direct impact on infectious disease. SUMMARY There is clear evidence on the causes and consequences of malnutrition as well as effective interventions to prevent undernutrition. The next step is to implement these packages of interventions at large scale. A global effort is required that should entail unified and compelling advocacy among governments, lead organizations, and institutions.

Abstract
Chronic pancreatitis is a progressive fibroinflammatory disease that exists in large-duct (often with intraductal calculi) or small-duct form. In many patients this disease results from a complex mix of environmental (eg, alcohol, cigarettes, and occupational chemicals) and genetic factors (eg, mutation in a trypsin-controlling gene or the cystic fibrosis transmembrane conductance regulator); a few patients have hereditary or autoimmune disease. Pain in the form of recurrent attacks of pancreatitis (representing paralysis of apical exocytosis in acinar cells) or constant and disabling pain is usually the main symptom. Management of the pain is mainly empirical, involving potent analgesics, duct drainage by endoscopic or surgical means, and partial or total pancreatectomy. However, steroids rapidly reduce symptoms in patients with autoimmune pancreatitis, and micronutrient therapy to correct electrophilic stress is emerging as a promising treatment in the other patients. Steatorrhoea, diabetes, local complications, and psychosocial issues associated with the disease are additional therapeutic challenges.

Abstract
Nutrition interventions play a central role in the treatment and management of inflammatory bowel disease in children. Malnutrition is a common presenting symptom in both pediatric ulcerative colitis and Crohn's disease and is associated with increased morbidity. Providing macronutrients can improve growth; likewise, identifying and correcting micronutrient deficiencies can improve comorbid conditions like osteopenia and anemia. Although many patients manipulate their diets to help treat their inflammatory bowel disease, only parenteral nutrition with bowel rest and exclusive enteral nutrition therapy have been shown effective for the treatment of inflammatory bowel disease.

Abstract
A randomized, double-blind, placebo-controlled trial was carried out to investigate the effects of micronutrients supplementation on immunity and the incidence of common infections in type 2 diabetic outpatients. A total of 196 type 2 diabetic outpatients were randomized to receive tablets of micronutrients (n=97) or placebo (n=99) for 6 months. Individualized dietary energy intake and daily physical activity were recommended. Anthropometric measurements, blood biochemical variables and the incidence of common infections were measured at baseline and at 6 months. Data on diet, exercise and infection (upper respiratory tract infection, skin infection, urinary and genital tract infections, other infections) were recorded 1 month before the study and every month during the study. Blood concentrations of total protein, iron (Fe), folic acid and hemoglobin increased and unsaturated iron-binding capacity(UIBC) levels were decreased in the micronutrients supplementation group compared to the placebo group at 6 months. Moreover, at 6 months, compared to the placebo group, the blood concentrations of IgE, CD4+, CD4+/CD8+, WBC, lymphocyte counts, basophilic leukocyte increased and CD8+ count decreased in the supplementation group, and the levels of IgA, IgM, IgG and complements C3 and C4 did not differ. The incidence of upper respiratory infection, whitlow, dermapostasis, vaginitis, urinary tract infection, gingivitis and dental ulcer were lower and body temperature and duration of fever greatly improved in the supplementation than the placebo group. These data indicated that supplementation of micronutrients might increase immune function and reduce the incidence of common infections in type 2 diabetic outpatients.

Abstract
UNLABELLED Depression is associated with nutritional deterioration in older persons and is highly prevalent among people of low socioeconomic status (LSES). OBJECTIVES To determine the prevalence of depressive symptoms and food insufficiency, and to examine the relationship between dietary intake, food insufficiency and depression, in LSES community dwelling elderly. DESIGN Cross-sectional study. SETTING Lod, a town in the central Israel. PARTICIPANTS Community-dwelling welfare recipients aged 60 to 92. MEASUREMENTS Depression was assessed by 15-item Geriatric Depression Scale (GDS-short version), using a score ≥ 10 as the cut off point for clinically important depressive symptoms. Dietary intake was evaluated using a 24-hour dietary recall. Food insufficiency was defined by participants reporting that they did not have enough food to eat " sometimes " or " often " . RESULTS This study reports on 112 persons aged 60 years and above (27.1% men). The prevalence of depression in this population was 47%; 25% of the study sample was classified as " food insufficient " . Macronutrients intake was similar for depressed and non-depressed persons, except for polyunsaturated fats which was lower among the depressed group (7.9 ± 4.9 vs.11.0 ± 7.5 g/day in the non-depressed, p=0.03). Vitamins and minerals intake was lower than recommended for both groups; vitamin E intake was associated with depression. In regression models controlling for confounding variables, an increase of 1 mg in vitamin E intake and 1 gram in polyunsaturated fatty acids (PUFA) intake was associated with lower risk for depression (OR=0.73, p=0.008 and OR=0.86, p=0.007 respectively) Participants who reported food insufficiency were 10 times more likely to be depressed compared with those who reported sufficient food. CONCLUSIONS Given the evaluated adverse association between depressive symptoms and food insufficiency, more efforts are needed to guarantee adequate food intake, particularly foods rich in vitamin E and PUFA, in poor elderly people. Further studies are needed to clarify the temporal relationship between the emotional and nutritional domains in this vulnerable population.

Abstract
BACKGROUND Airway infection leads to progressive damage of the lungs in cystic fibrosis (CF), partly due to oxidative stress. Supplementation of antioxidant micronutrients (vitamin E, vitamin C, ß-carotene and selenium) may help maintain an oxidant-antioxidant balance. Current literature suggests a relationship between oxidative status and lung function. OBJECTIVES To synthesize existing knowledge of the effect of vitamin C, vitamin E, ß-carotene and selenium in CF lung disease. SEARCH STRATEGY The Cochrane CF and Genetic Disorders Group CF Trials Register, PubMed, CINAHL and AMED were searched using detailed search strategies. We contacted authors of included studies and checked reference lists of these studies for additional, potentially relevant studies.Last search of CF Trials Register: 09 September 2010. SELECTION CRITERIA Randomized controlled trials and quasi-randomized controlled trials of people with CF with explicitly stated diagnostic criteria, comparing vitamin E, vitamin C, ß-carotene and selenium (individually or in combination) to placebo or standard care. DATA COLLECTION AND ANALYSIS Two authors independently selected trials, extracted data and assessed risk of bias. We contacted trialists to obtain missing information. Primary outcomes are lung function and quality of life; secondary outcomes are oxidative stress, inflammation, body mass index, days on antibiotics and adverse events during supplementation. If meta-analysed, studies were subgrouped according to combined or single antioxidant supplementation. MAIN RESULTS Four randomized controlled trials and one quasi-randomized controlled trial were included; only three trials (87 participants) presented data suitable for analysis. Based on two trials, there was no significant improvement in lung function; one trial indicated significant improvement in quality of life favouring control, mean difference -0.06 points on the quality of well-being scale (95% confidence interval -0.12 to -0.01). Based on two trials, selenium-dependent glutathione peroxidase enzyme significantly improved in favour of combined supplementation, mean difference 1.60 units per gram of haemoglobin (95% CI 0.30 to 2.90) and selenium supplementation, mean difference 10.20 units per gram of haemoglobin (95% CI 2.22 to 18.18). All plasma antioxidant levels, except vitamin C, significantly improved with supplementation. AUTHORS' CONCLUSIONS There appears to be conflicting evidence regarding the clinical effectiveness of antioxidant supplementation in CF. Based on the evidence, antioxidants appear to decrease quality of life and oxidative stress; however, few trials contributed data towards analysis. Further trials examining clinically important outcomes and elucidation of a clear biological pathway of oxidative stress in CF are necessary before a firm conclusion regarding effects of antioxidants supplementation can be drawn.

Abstract
PURPOSE OF REVIEW To review the most recent aspects of nutrition therapy of cirrhotic patients on the waiting list for liver transplantation. RECENT FINDINGS Undernutrition has been widely reported among these patients, despite the lack of consensus on the best nutritional assessment tools in this population. Nutrition therapy has been marked by controversy. Nonetheless, recent findings have pointed out to the important role of the nutrition status and of some specific nutrients on the outcome of these patients. SUMMARY We report the latest findings on nutrition care of patients with end-stage liver disease on the waiting list for liver transplantation such as the impact of the nutritional status on outcome, probiotic and branched-chain amino acid supplementation, as well as the use of immunomodulating formula. Another important strategy that has been shown to improve these patients' nutritional care is the offering of nocturnal meals and micronutrient supplementation.

Abstract
BACKGROUND Diarrhoea is a major cause of morbidity and mortality among infants and children worldwide, especially in low- and middle-income countries. Human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) is a condition that similarly disproportionately affects low- and middle-income countries; of the nearly 2.1 million children under age 15 years living with HIV/AIDS, the large majority reside in sub-Saharan Africa. Infants and children with HIV infection have more frequent and more severe diarrhoea than children without HIV. Interventions including vitamin A, zinc and cotrimoxazole may contribute substantially to preventing diarrhoea in children with HIV infection or exposure to HIV. OBJECTIVES We perform a systematic review of randomised controlled trials and nonrandomised studies that examine the effectiveness of vitamin A, zinc and cotrimoxazole on mortality and morbidity from diarrhoea in HIV-infected and -exposed infants and children. SEARCH STRATEGY Electronic databases including Pubmed, Central and EMBASE were searched without limits to language from 1980 to April 2010. Conference database searches were performed, experts were contacted and bibliographies were handsearched. SELECTION CRITERIA Randomised controlled trials (RCTs) and nonrandomised studies (NRSs) that examined the effectiveness of the three interventions were included. DATA COLLECTION AND ANALYSIS Two reviewers independently assessed citations for eligibility and double-extracted included studies. Assessment of bias of individual studies was performed independently by both reviewers. Only two summary estimates were performed due to heterogeneity in study design and interventions. MAIN RESULTS Four RCTs were identified for vitamin A. One RCT was identified for zinc. One RCT and two NRSs were identified for cotrimoxazole. Vitamin A reduced mortality overall in children with HIV infection (four studies). A pooled estimate of three studies for reduction in mortality from vitamin A compared to placebo had a relative risk (DerSimonian and Laird method, random effects) of 0.50 (95% confidence interval (CI): 0.31 to 0.79) in 267 patients. Diarrheoa-specific mortality did not reach statistical significance and diarrhoeal morbidity outcomes were variable in three trials. Zinc supplementation reduced the number of physician visits for watery diarrhoea in one trial. Cotrimoxazole reduced mortality and hospitalisations compared to placebo in one RCT, although diarrhoea-specific morbidities were not significant. AUTHORS' CONCLUSIONS Vitamin A shows benefits in reduction of mortality in HIV-infected children. The effect of vitamin A on children with HIV exposure is not clear and needs further review. Zinc and combination vitamin A, zinc and micronutrient supplementation did not show an effect compared to vitamin A alone in children with HIV infection. Cotrimoxazole reduced mortality and some morbidity in children with HIV infection. Further research may clarify the effects of these interventions on morbidity from diarrhoea and in the population of children with HIV exposure.

Abstract
Low serum concentrations of micronutrients, intestinal abnormalities, and an inflammatory state have been associated with HIV progression. These may be ameliorated by micronutrients, N-acetyl cysteine, probiotics, and prebiotics. This review aims to integrate the evidence from clinical trials of these interventions on the progression of HIV. Vitamin B, C, E, and folic acid have been shown to delay the progression of HIV. Supplementation with selenium, N-acetyl cysteine, probiotics, and prebiotics has considerable potential, but the evidence needs to be further substantiated. Vitamin A, iron, and zinc have been associated with adverse effects and caution is warranted for their use.

Abstract
Dietary supplementation with nutrients that have physiologic effects on immune function has been shown to be beneficial in subsets of patients with surgical and medical critical illness. However, several meta-analyses have suggested potential harm when immune nutrients are used inappropriately. This has led to concern among clinicians that in turn has curtailed the more widespread use of immunonutrition as a therapeutic modality. This article discusses the mechanisms by which immune nutrients can be used to modulate alterations in innate and acquired immunity associated with critical illness. In addition, recent evidence-based clinical practice guidelines for use of immunonutrition in adults is reviewed as a means to clarify some of the more controversial issues and provide a "roadmap" for the practitioner.

Abstract
The growing prevalence of diabetes parallels the increased prevalence of obesity. Overweight and obese individuals with diabetes who attempt weight reduction face considerable challenges. However, several recent studies showed that weight reduction in patients with diabetes is feasible using a multidisciplinary approach that incorporates structured dietary intervention and meal replacements (MRs). Nutritionally complete MRs are shown to be useful at the start of weight reduction programs and for weight maintenance because of their nutrition adequacy. However, patients using this approach need to monitor their blood glucose levels closely and may need to adjust their diabetes medications. Most commercial MRs are currently fortified with vitamins and minerals to prevent long-term deficiency in essential micronutrients that are commonly seen in low-calorie diet plans. They also come in different flavors and formats that improve their general acceptability. To successfully initiate weight loss, MRs are generally used as absolute replacement of an agreed upon number of meals/snacks. This article covers the use of MRs for patients with diabetes for short-term and long-term weight reduction in clinical trials and real-world clinical practice.

Abstract
BACKGROUND Evaluations of large-scale health and nutrition programmes in developing countries are needed for determining the effectiveness of interventions. This article critically analyses a non-governmental organization (NGO)-led large-scale, multi-country, 10-year micronutrient and health (MICAH) programme with an 'adequacy evaluation', that is, a documentation of time trends in the expected direction. METHODS MICAH was implemented from 1996 to 2005 in selected areas of Ethiopia, Ghana, Malawi and Tanzania, reaching >6 million people with numerous health and nutrition interventions. Coverage and impact were monitored through surveys at baseline, midpoint and end of funding. The data were subjected to post-hoc methods of quality determination, and, if of suitable quality, included in the adequacy evaluation. RESULTS Most collected data were of moderate or high quality and therefore included in the adequacy evaluation. There were moderate to large improvements in vitamin A status in Ethiopian school-age children, children <5 years of age in Tanzania and Ghana and mothers in Ghana. Iodine status improved in Malawi and Tanzania. Anaemia rates and malaria prevalence decreased in women, pregnant women and pre-school children in Ghana, Malawi and Tanzania, but anaemia increased in Ethiopian women. Large increases were reported for rates of exclusive breastfeeding and immunization. Child growth improved to the maximum that would be predicted with the given interventions. CONCLUSIONS Numerous nutrition and health impacts were observed in the intervention areas, often of a magnitude equal to or larger than observed in controlled interventions or trials. These results show the value of integrated long-term interventions.

Abstract
Autism spectrum disorder (ASD) is often accompanied by self-injurious behavior (SIB), aggression, and tantrums, symptoms that have reportedly improved with micronutrient (vitamins and minerals) treatment. The current study took advantage of naturally occurring differences in parental preferences for treatment approaches. The micronutrient group asked for treatment without pharmaceuticals (n = 44, aged 2-28 years at entry [M = 8.39 +/- 5.58]). Their records were matched with those of 44 similar children whose families requested conventional treatment (medication group). Both groups improved on both the Childhood Autism Rating Scale and the Childhood Psychiatric Rating Scale (all p values <0.0001). Both groups also exhibited significant decreases in total Aberrant Behavior Checklist scores, but the micronutrient group's improvement was significantly greater (p < 0.0001). SIB Intensity was lower in the micronutrient group at the end of the study (p = 0.005), and improvement on the Clinical Global Impressions scale was greater for the micronutrient group (p = 0.0029). It is difficult to determine whether the observed changes were exerted through improvement in mood disorder or through an independent effect on autistic disorder. There were some advantages to treatment with micronutrients-lower activity level, less social withdrawal, less anger, better spontaneity with the examiner, less irritability, lower intensity SIB, markedly fewer adverse events, and less weight gain. Advantages of medication management were insurance coverage, fewer pills, and less frequent dosing.

Abstract
The study was undertaken to evaluate the efficacy of multivitamin and micronutrient supplementation in azoospermic patients with maturation arrest. A total of 35 azoospermic patients showing maturation arrest on testicular biopsy were recruited in this study. The patients were divided into two groups. Untreated group (n=11) without any treatment and treated group (n=24) who received multivitamins, micronutrients and co-enzyme Q10. The sperm concentration, motility and morphology were evaluated at monthly interval. The results showed reduction in liquefaction time and relative viscosity of the semen in the treated group. Further, in treated group there was appearance of spermatozoa (4.0 million/ml) exhibiting progressive motility (7%) and normal morphology (6%), even in the first follow up visit. The sperm count, motility and normal morphology increased significantly on subsequent visits. Within 3 months (3 visits) 2 pregnancies were reported. These observations indicate that multivitamin and micronutrient supplementation improve the qualitative and quantitative parameters of seminogram in patients with azoospermia of maturation arrest.

Abstract
Micronutrient therapy, designed to buttress tissue methyl and thiol groups, curbs attacks and controls background pain in patients with chronic pancreatitis, irrespective of aetiology. This outcome and the premises upon which it is based facilitate an understanding of links with mutations in genes for hereditary pancreatitis and cystic fibrosis, demography, and predisposition to pancreatic cancer. Above all, there is an opportunity for prophylaxis in individuals at high risk of developing the disease.

Abstract
A truly integrative approach to mental health includes a thorough assessment of dietary habits, level of exercise/physical activity, environmental exposures, medications, comorbid conditions, life stressors, level of social support, and family history. A complete physical exam and appropriate laboratory and imaging studies should be utilized to rule out underlying causes of depressed or anxious mood. Many patients will benefit from the use of specific dietary supplements, such as a multivitamin-mineral high in B-vitamins and omega-3 fatty acid. And no matter what the underlying cause of the mood disorder, patients should be counseled about the relationship between food and mood, for the evidence now substantiates what laypeople and medical professionals have long known intuitively: the way we eat affects the way we feel. The Western diet consumed in a growing number of countries is devoid of many of the key nutrients critical for the proper functioning of the central nervous system. When making dietary recommendations, clinicians should consider a low-glycemic, modified Mediterranean diet rich in fruits, vegetables, whole grains, and seafood (if not vegetarian) and low in processed, refined foods for optimizing mental health. A future article on the topic of nutrition and mental health will address the role of nutraceuticals and herbal medicines in mental health.

Abstract
Pregnancy anemia and pregnancy-induced hypertension (PIH) are common and potentially dangerous disorder in human pregnancy, and nutritional status of pregnant women is one of the leading causes. Chlorella contains large quantities of folate, vitamin B-12 and iron, and can help improve anemia and hypertensive disorder. Our objective was to investigate the preventive effects of Chlorella supplement on pregnancy anemia and PIH in Japanese pregnant women. A total of 70 pregnant women were placed into the control group (n = 38) or the Chlorella group (n = 32). The subjects in the Chlorella group were supplemented daily from 12th-18th wk of gestation until delivery with 6 g of Chlorella supplement. The proportion of anemic (hemoglobin level < 11 g/dL) subjects in the Chlorella group were significantly lower compared with the control group at the second and third trimesters. Additionally, in the Chlorella group, the incidences of proteinuria and edema, signs of PIH, were significantly lower during the third trimester. These results suggest that Chlorella supplementation significantly reduces the risk of pregnancy associated anemia, proteinuria and edema. Chlorella supplement may be useful as a resource of natural folate, vitamin B-12 and iron for pregnant women.

Abstract
PURPOSE OF REVIEW The purpose of the present review is to evaluate the most recent evidence for a role of antioxidant nutrients in the prevention or delay in progression of age-related macular degeneration (AMD), a major cause of visual impairment and blindness in the aging population. RECENT FINDINGS Recent human studies (>2008) report a decreased AMD risk with increased intakes of lutein/zeaxanthin, B vitamins, zinc and docosahexaenoic acid but an increased risk with increased intakes of beta-carotene and vitamin E. These latter findings are inconsistent with previous reports (<2008). SUMMARY Findings on the association of certain antioxidants and docosahexaenoic acid support a role for nutrition in a decreased risk of AMD. The inconsistent findings of an increased risk with increased intake of beta-carotene and vitamin E warrants continued investigation into these relationships.

Abstract
The hemodialysis (HD) patient is often marked by constant malnutrition, inflammation, and atherosclerosis, resulting in an increased risk of cardiovascular events and mortality. This chronic inflammatory state is often the result of increased oxidative stress. Nutritional supplementation may become an additional therapy to lower this inflammatory burden. By providing these patients with nutritional supplement and antioxidant therapies consisting of alpha-lipoic acid, cholecalciferol, ascorbic acid, and Gamma-Tocopherol, providers may reduce overall inflammation and improve HD outcomes in patients with end-stage renal disease.
