Helicobacter pylori infection is the cause of 90% of non-cardia gastric cancer. Several dietary elements have been identified as possible contributors to H. pylori infection and its advancement through various pathways. Based on the anti-inflammatory and anti-microbial effects of a diet low in omega-6 and high in omega-3 polyunsaturated fatty acids (PUFAs), this study aimed to assess the ratio of dietary omega-6 to omega-3 PUFAs and the risk of developing H. pylori. The present case-control study was conducted on 150 cases with H. pylori infection and 302 controls. The omega-6 to omega-3 ratio was calculated using food intake information sourced from a validated food frequency questionnaire. Physical activity and demographic data were collected through a related questionnaire. The association between the odds of H. pylori infection and the omega-6 to omega-3 ratio was evaluated using logistic regression models. A p value < 0.05 was considered statistically significant. The findings revealed that individuals in the third tertile had significantly higher odds of H. pylori (odds ratio [OR], 2.10; 95% confidence interval [CI], 1.30-3.40) in the crude model. Furthermore, even after adjusting the potential confounders including sex, age, body mass index, physical activity, energy intake, alcohol, and smoking status, this association remained significant (fully adjusted model: OR, 2.00; 95% CI, 1.17-3.34). Our study revealed a higher ratio of omega-6 to omega-3 was related to a higher likelihood of H. pylori infection. Therefore, it is advisable to maintain a balanced intake of PUFAs in the diet.

Vegan diets are widely promoted as protective against cardiovascular disease (CVD); however, removing all animal foods from a human\'s diet usually causes unfavorable health consequences. Our hominin ancestors began consuming meat, fish, seafood, and eggs >2 million years ago. Consequently, humans are genetically adapted to procure nutrients from both plant and animal sources. In contrast, veganism is without evolutionary precedent in Homo sapiens species. Strict adherence to a vegan diet causes predictable deficiencies in nutrients including vitamins B12, B2, D, niacin, iron, iodine, zinc, high-quality proteins, omega-3, and calcium. Prolonged strict veganism increases risk for bone fractures, sarcopenia, anemia, and depression. A more logical diet is a plant-forward omnivorous eating pattern that emphasizes generous consumption of natural, unprocessed foods predominantly from plants. To balance this diet, modest amounts of wholesome animal foods, such wild-caught fish/seafood, pasture-raised meat and eggs, and fermented unsweetened dairy should be consumed regularly.

BACKGROUND: Preeclampsia is a complication during pregnancy characterised by new-onset hypertension and proteinuria that develops after 20 weeks of gestation. Dyslipidemia in pregnancy is correlated with an increased risk of preeclampsia. However, the dynamic changes in lipid metabolic product, particularly fatty acid fraction, in preeclampsia maternal circulation, are not well understood. This study aimed to investigate fatty acid fraction in preeclampsia maternal blood compared with normotensive normal pregnancy.
METHODS: A total of 34 women who developed preeclampsia and 32 women with normotensive normal pregnancy were included in our case-control study. Maternal blood samples were collected for serum fatty acid fractions analysis and other biochemical parameters. Serum fatty acid fractions included long-chain polyunsaturated fatty acid (LCPUFA), monounsaturated fatty acid (MUFA), saturated fatty acid, and total fatty acid, measured with gas chromatography-mass spectrometry (GC-MS). The mean difference of fatty acid level was analysed using parametric and non-parametric bivariate analysis based on normality distributed data, while the risk of preeclampsia based on fatty acid fraction was analysed using a logistic regression model.
RESULTS: Women with preeclampsia have lower high-density lipoprotein (53.97 ± 12.82 mg/dL vs. 63.71 ± 15.20 mg/dL, p = 0.006), higher triglyceride (284.91 ± 97.68 mg/dL vs. 232.84 ± 73.69 mg/dL, p = 0.018) than that in the normotensive group. Higher palmitoleic acid was found in women with preeclampsia compared to normotensive normal pregnancy (422.94 ± 195.99 vs. 325.71 ± 111.03 μmol/L, p = 0.037). The binary logistic regression model showed that pregnant women who had total omega-3 levels within the reference values had a higher risk of suffering preeclampsia than those with the higher reference value (odds ratio OR (95% CI): 8,5 (1.51-48.07), p = 0.015). Pregnant women who have saturated fatty acid within reference values had a lower risk for suffering preeclampsia than those in upper reference value (OR (95% CI): 0.21 (0.52-0.88), p = 0.032).
CONCLUSIONS: Overall, palmitoleic acid was higher in women with preeclampsia. Further analysis indicated that reference omega-3 in and high saturated fatty acid serum levels are characteristics of women with preeclampsia.

Asparaginase-induced hypertriglyceridemia can have a spectrum of clinical presentations, from being asymptomatic to having life-threatening thrombosis or hyperviscosity syndrome. At present, there is no recommendation on routine lipid monitoring during asparaginase-containing treatment phase, nor a standardized guideline on its management. Two cases are presented here to illustrate the effects of concurrent infection on asparaginase-induced hypertriglyceridemia in patients with high-risk ALL and the use of SMOFlipid infusion as a treatment option in an acute situation.

The role of diet in rheumatoid arthritis (RA) has been the topic of extensive research. The present review aimed to present and appraise the studies assessing adherence to the Mediterranean diet (MD) and the primary/secondary prevention of rheumatoid arthritis. Based on the available studies, the evidence appears low and adherence to the MD does not appear to affect RA indices.

Attention deficit disorder with and without hyperactivity (ADHD) in children is associated with decreased 24-h heart rate variability (HRV). Previous research has shown that supplementation of omega-3-fatty acid increases HRV. Here, we aimed to investigate whether the supplementation of omega-3-fatty acids would increase 24-h HRV in an uncontrolled case series of children with ADHD. HRV was recorded in 18 children and adolescents (age 13.35 ± 2.8 years) before and after omega-3 supplementation. Preliminary results indicate that omega-3 supplementation in children with AD(H)D may reduce mean heart rate and increase its variability. Future studies would do well to implement randomized, placebo-controlled designs with greater methodological rigor.

Omega-3 long chain polyunsaturated fatty acid supplementation (n-3 LCPUFA) for treatment of Autism Spectrum Disorder (ASD) is popular. The results of previous systematic reviews and meta-analyses of n-3 LCPUFA supplementation on ASD outcomes were inconclusive. Two meta-analyses were conducted; meta-analysis 1 compared blood levels of LCPUFA and their ratios arachidonic acid (ARA) to docosahexaenoic acid (DHA), ARA to eicosapentaenoic acid (EPA), or total n-6 to total n-3 LCPUFA in ASD to those of typically developing individuals (with no neurodevelopmental disorders), and meta-analysis 2 compared the effects of n-3 LCPUFA supplementation to placebo on symptoms of ASD. Case-control studies and randomised controlled trials (RCTs) were identified searching electronic databases up to May, 2016. Mean differences were pooled and analysed using inverse variance models. Heterogeneity was assessed using I² statistic. Fifteen case-control studies (n = 1193) were reviewed. Compared with typically developed, ASD populations had lower DHA (-2.14 [95% CI -3.22 to -1.07]; p < 0.0001; I² = 97%), EPA (-0.72 [95% CI -1.25 to -0.18]; p = 0.008; I² = 88%), and ARA (-0.83 [95% CI, -1.48 to -0.17]; p = 0.01; I² = 96%) and higher total n-6 LCPUFA to n-3 LCPUFA ratio (0.42 [95% CI 0.06 to 0.78]; p = 0.02; I² = 74%). Four RCTs were included in meta-analysis 2 (n = 107). Compared with placebo, n-3 LCPUFA improved social interaction (-1.96 [95% CI -3.5 to -0.34]; p = 0.02; I² = 0) and repetitive and restricted interests and behaviours (-1.08 [95% CI -2.17 to -0.01]; p = 0.05; I² = 0). Populations with ASD have lower n-3 LCPUFA status and n-3 LCPUFA supplementation can potentially improve some ASD symptoms. Further research with large sample size and adequate study duration is warranted to confirm the efficacy of n-3 LCPUFA.
