Background: Folate and vitamin B12 are well-known as essential nutrients that play key roles in the normal functions of the brain. Inflammatory processes play at least some role in the pathology of AD. Effective nutritional intervention approaches for improving cognitive deficits that reduce the peripheral inflammatory cytokine levels have garnered special attention.
Objective: The present study aimed to determine whether supplementation with folic acid and vitamin B12, alone and in combination improves cognitive performance via reducing levels of peripheral inflammatory cytokines.
Methods: 240 participants with MCI were randomly assigned in equal proportion to four treatment groups: folic acid alone, vitamin B12 alone, folic acid plus vitamin B12 or control without treatment daily for 6 months. Cognition was measured with WAIS-RC. The levels of inflammatory cytokines were measured using ELISA. Changes in cognitive function or blood biomarkers were analyzed by repeatedmeasure analysis of variance or mixed-effects models. This trial has been registered with trial number ChiCTR-ROC-16008305.
Results: Compared with control group, the folic acid plus vitamin B12 group had significantly greater improvements in serum folate, homocysteine, vitamin B12 and IL-6, TNF-α, MCP-1. The folic acid plus vitamin B12 supplementation significantly changed the Full Scale IQ (effect size d = 0.169; P = 0.024), verbal IQ (effect size d = 0.146; P = 0.033), Information (d = 0.172; P = 0.019) and Digit Span (d = 0.187; P = 0.009) scores. Post hoc Turkey tests found that folic acid and vitamin B12 supplementation was significantly more effective than folic acid alone for all endpoints.
Conclusions: The combination of oral folic acid plus vitamin B12 in MCI elderly for six months can significantly improve cognitive performance and reduce the levels of inflammatory cytokines in human peripheral blood. The combination of folic acid and vitamin B12 was significantly superior to either folic acid or vitamin B12 alone.

Unlabelled: The Ketogenic Diet (KD) is a non-pharmacological strategy for drug-resistant epilepsy (DRE) and inborn errors of metabolism (Glut-1 deficiency) management. KD is characterized by being restrictive, affecting micronutrient intake. There are different modalities of KD in which food intake and nutritional deficiencies vary.

Objectives: Vitamin B12 (Cobalamin or Cbl) plays a crucial role in normal human growth and development, as well as in neurological, cardiovascular, and immune systems. Previous studies reported association of high levels of cobalamin with solid cancers, hematological disorders, and liver diseases. Reporting the frequency of comorbid diseases with high serum Vitamin B12 level in patients attending KSAMC at Madinah.

Introduction: The increasing adoption of strict vegetarian diets during pregnancy has raised concerns about their effects on maternal and neonatal outcomes. This systematic review and meta-analysis aimed to assess the impact of strict vegetarian diets on key pregnancy outcomes, including neonatal birth weight, small-for-gestational-age (SGA) infants, gestational diabetes mellitus (GDM), hypertensive disorders, and gestational weight gain (GWG).
Methods: A comprehensive literature search across multiple databases yielded eight studies from various countries, involving a total of 72,284 participants.
