Parks NE, Jackson-Tarlton CS, Vacchi L, Merdad R, Johnston BC · The Cochrane database of systematic reviews · 2020 · n=217

Multiple sclerosis (MS) is a common demyelinating disease of the central nervous system. Although the exact pathogenesis remains unknown, the leading theory is that it results from immune system dysregulation. Approved disease-modifying therapy appears to modulate the immune system to improve MS-related outcomes. There is substantial interest in the ability of dietary interventions to influence MS-related outcomes. This is an update of the Cochrane Review 'Dietary interventions for multiple sclerosis' (Farinotti 2003; Farinotti 2007; Farinotti 2012). To assess the effects of dietary interventions (including dietary plans with recommendations for specific whole foods, macronutrients, and natural health products) compared to placebo or another intervention on health outcomes (including MS-related outcomes and serious adverse events) in people with MS. On 30 May 2019, we searched CENTRAL, MEDLINE, Embase, and Web of Science. We also searched ClinicalTrials.gov, World Health Organization

Bariatric Surgery in Obesity: Effects on Gut Microbiota and Micronutrient Status.

Ciobârcă D, Cătoi AF, Copăescu C, Miere D, Crișan G · Nutrients · 2020

Obesity is associated with reduced gut microbial diversity and a high rate of micronutrient deficiency. Bariatric surgery, the therapy of choice for severe obesity, produces sustained weight loss and improvements in obesity-related comorbidities. Also, it significantly alters the gut microbiota (GM) composition and function, which might have an important impact on the micronutrient status as GM is able to synthesize certain vitamins, such as riboflavin, folate, B12, or vitamin K2. However, recent data have reported that GM is not fully restored after bariatric surgery; therefore, manipulation of GM through probiotics represents a promising therapeutic approach in bariatric patients. In this review, we discuss the latest evidence concerning the relationship between obesity, GM and micronutrients, the impact of bariatric surgery on GM in relation with micronutrients equilibrium, and the importance of the probiotics' supplementation in obese patients submitted to surgical treatment.

Sivanand A, Gulliver WP, Josan CK, Alhusayen R, Fleming PJ · Journal of cutaneous medicine and surgery · 2020 · n=1279

Hidradenitis suppurativa (HS) is a common inflammatory disorder characterized by recurrent, painful, and malodorous abscesses and nodules predominantly in skin folds. HS is associated with substantial morbidity and poor quality of life. There are no curative therapies, and the only approved biologic drug has variable efficacy and requires high doses, making adjunct treatments crucial. An important risk factor for disease severity is obesity. Our primary objective was to conduct a systematic review examining weight loss and dietary interventions, in HS. Our secondary objective was to examine nutritional supplements in HS.A systematic literature search was conducted using Medline, EMBASE, and the Cochrane Database. We included all study types in adults (>18 years), with a minimum sample size of 5, examining the effects of any dietary or weight loss intervention on HS severity. Two authors screened n = 1279 articles of which 9 met inclusion criteria. All included studies were observati

The increasing recognition of cyclic vomiting syndrome (CVS) in adults prompted the development of these evidence-based guidelines on the management of CVS in adults, which was sponsored by the American Neurogastroenterology and Motility Society (ANMS) and the Cyclic Vomiting Syndrome Association (CVSA). GRADE (Grading of Recommendations, Assessment, Development, and Evaluation) framework was used and a professional librarian performed the literature search. The expert committee included the President of the CVSA who brought a patient perspective into the deliberations. The committee makes recommendations for the prophylaxis of CVS, treatment of acute attacks, diagnosis, and overall management of CVS. The committee strongly  recommends that adults with moderate-to-severe CVS receive a tricyclic antidepressant (TCA), such as amitriptyline, as a first-line prophylactic medication and receive topiramate or aprepitant as alternate prophylactic medications. Zonisamide or levetiracetam

The Role of Water-Soluble Vitamins and Vitamin D in Prevention and Treatment of Depression and Seasonal Affective Disorder in Adults.

Jahan-Mihan A, Stevens P, Medero-Alfonso S, Brace G, Overby LK, Berg K · Nutrients · 2024

Depression is a major global health concern expected to worsen by 2030. In 2019, 28 million individuals were affected by depressive disorders. Dietary and supplemental vitamins show overall favorable preventative and therapeutic effects on depression. B vitamins are crucial for neurological function and mood regulation. Deficiencies in these vitamins are linked to depression. Studies on individual B vitamins show promise in improving depressive symptoms, particularly thiamin, riboflavin, niacin, and folate. Vitamin C deficiency may heighten depressive symptoms, but its exact role is not fully understood. Seasonal Affective Disorder (SAD) is associated with insufficient sunlight exposure and vitamin D deficiency. Vitamin D supplementation for SAD shows inconsistent results due to methodological variations. Further investigation is needed to understand the mechanisms of vitamins in depression treatment. Moreover, more research on SAD and light therapy's efficacy and underlying mechanisms

Practical supplements for prevention and management of migraine attacks: a narrative review.

Hajhashemy Z, Golpour-Hamedani S, Eshaghian N, Sadeghi O, Khorvash F, Askari G · Frontiers in nutrition · 2024

Migraine is one of the most debilitating neurological disorders that causes frequent attacks of headaches and affects approximately 11% of the global population. Deficient or even insufficient levels of vital nutrients would increase the severity and frequency of migraine attacks. Therefore, we aimed to examine the practical supplements for the prevention and management of migraine attacks. This narrative review study was conducted by searching PubMed, ISI web of science, EMBASE, Google Scholar, and Scopus using the keywords of "dietary supplement" and "migraine" plus their MeSH terms. Original articles published in English language from their inception to July 27th, 2024, studies that investigated adult population (aged >18 years), and those assessing the impact of intended nutrient supplementation on clinical symptoms of migraine were included in the study. Oxidative stress and low intake of antioxidants would be risk factors for migraine attacks by inducing inflammation.

Causes and Clinical Sequelae of Riboflavin Deficiency.

McNulty H, Pentieva K, Ward M · Annual review of nutrition · 2023

Riboflavin, in its cofactor forms flavin adenine dinucleotide (FAD) and flavin mononucleotide (FMN), plays fundamental roles in energy metabolism, cellular antioxidant potential, and metabolic interactions with other micronutrients, including iron, vitamin B6, and folate. Severe riboflavin deficiency, largely confined to low-income countries, clinically manifests as cheilosis, angular stomatitis, glossitis, seborrheic dermatitis, and severe anemia with erythroid hypoplasia. Subclinical deficiency may be much more widespread, including in high-income countries, but typically goes undetected because riboflavin biomarkers are rarely measured in human studies. There are adverse health consequences of low and deficient riboflavin status throughout the life cycle, including anemia and hypertension, that could contribute substantially to the global burden of disease. This review considers the available evidence on causes, detection, and consequences of riboflavin deficiency, ranging from clin

Pilot Study for the Evaluation of the Effectiveness of Natural Versus Synthetic Vitamin B Complexes in Humans.

n=30 · NCT03444155 · COMPLETED · COMPLETED

In a cross-over study the investigators evaluate the effects of natural (Panmol-B-Complex) (Pan \[Greek\] = all; moles \[Latin\] = molecules/particles - brand name) versus synthetic vitamin B complexes to identify the bioavailability of distinct vitamins as well as long-term effects. The primary hypothesis for this study: "Natural Vitamin B-complexes are as effective as synthetic Vitamin B-complexes or better." For this reason 30 subjects (18 to 65y; BMI \>19 to \<29) were recruited for this study. The study population was divided into 2 groups of each 15 subjects in a cross-over trial. Vitamin supplementation consisted of Thiamine (2.93 mg), Riboflavin (3.98 mg), Niacin (29.85 mg), Pantothenic acid (10.95 mg), Pyridoxine (3.38 mg), Biotin (0.108 mg), Folic acid (0.69 mg) and Cobalamin (8.85 µg) per day in both groups. Blood samples are taken at baseline - 1.5h after vitamin supplementation - 4h - 7h - 6 weeks - wash out phase I (2 weeks); start cross-over: baseline - 1.5h after vitamin supplementation - 4h - 7h - 6 weeks - washout phase II (6 weeks). In case of main target criteria Thiamin, Riboflavin, Pyridoxine, Folic acid and Cobalamin were measured in serum as well as total peroxides (µmol/L), peroxidase-activity (U/L), total antioxidant status (mmol/L) and polyphenols (mmol/L).
