The Effectiveness of Perinatal Omega-3 Supplements in Neurodevelopment and Physical Growth of 9- and 12-month-old Infants: A Follow-up of a Clinical Trial.

BACKGROUND: Omega-3 fatty acids (FAs) are essential long-chain polyunsaturated fatty acids (LCPUFAs) that are essential for optimal health and development. OBJECTIVE: The present study aimed to evaluate the effectiveness of maternal fish oil (containing omega-3 LCPUFA) intake from 21th week of pregnancy to 30 days postpartum for neurodevelopment and growth of infants at 9 and 12 months. METHODS: This was a follow-up study of a triple-blinded clinical trial. The study population was 9-- month-old infants. Their mothers were randomly divided into two groups of 75 people with a 1:1 ratio to take one fish oil supplement or a placebo daily. The anthropometric indicators of infants at months 9 and 12 and neurodevelopment at month 12 by the ASQ questionnaire were measured. In the fish oil and placebo groups, respectively, 73 and 71 infants at nine months, as well as 71 and 69 at 12 months, were analyzed. RESULTS: No statistically significant impact was observed following consuming omega-3 capsules on the neurodevelopmental domains, growth parameters, and the profile of maternal serum FAs (p > 0.05) except DHA. Neurodevelopmental problems were illustrated in one case in the intervention group and two cases in the placebo group. CONCLUSION: Perinatal relatively low-dose omega-3 LCPUFAs supplements indicated no statistically significant impacts on the growth and neurodevelopment of 9- and 12-month-old infants in a population with low consumption of marine products. Further studies investigating the effect of higher doses of omega-3 LCPUFAs are suggested.

Harnessing tumor-derived exosomes: A promising approach for the expansion of clinical diagnosis, prognosis, and therapeutic outcome of prostate cancer.

Prostate cancer is the second leading cause of men's death worldwide. Although early diagnosis and therapy for localized prostate cancer have improved, the majority of men with metastatic disease die from prostate cancer annually. Therefore, identification of the cellular-molecular mechanisms underlying the progression of prostate cancer is essential for overcoming controlled proliferation, invasion, and metastasis. Exosomes are small extracellular vesicles that mediate most cells' interactions and contain membrane proteins, cytosolic and nuclear proteins, extracellular matrix proteins, lipids, metabolites, and nucleic acids. Exosomes play an essential role in paracrine pathways, potentially influencing Prostate cancer progression through a wide variety of mechanisms. In the present review, we outline and discuss recent progress in our understanding of the role of exosomes in the Prostate cancer microenvironment, like their involvement in prostate cancer occurrence, progression, angiogenesis, epithelial-mesenchymal transition, metastasis, and drug resistance. We also present the latest findings regarding the function of exosomes as biomarkers, direct therapeutic targets in prostate cancer, and the challenges and advantages associated with using exosomes as natural carriers and in exosome-based immunotherapy. These findings are a promising avenue for the expansion of potential clinical approaches.

Is hyperemesis gravidarum associated with transient hyperthyroidism? A systematic review and meta-analysis.

Emerging evidence suggests an association of hyperemesis gravidarum (HG) with transient hyperthyroidism and high HCG levels. For synthesizing the current evidence to determine the association between HG with hormones related to thyroid function, a comprehensive systematic search was performed in the electronic databases comprised Medline, Web of Science, Scopus, Embase, ProQuest, and Cochrane Library up to December 2021. All published observational studies that evaluated the association of hyperemesis gravidarum with transient hyperthyroidism were investigated considering the PICO method. The standardized Joanna Briggs Institute Meta-Analysis of Statistics, Assessment, and Review Instrument were applied to appraise the included studies. Twenty-nine studies consisted of 6525 women included in the systematic review. Among them, 28 studies with 2446 participants were included in the meta-analysis. There were significant associations of HG with fT3 (MD: 1.31 pg/mL, 95% CI: 0.61 to 2.01), fT4 (MD: 1.95 ng/dL, 95% CI: 1.17 to 2.73), TSH (MD: -1.22µIU/mL, 95% CI: -1.75 to -0.68), TT4 (MD: 0.56 nmol/L, 95% CI:-0.43 to 1.24), and HCG (MD: 1.90IU/L, 95% CI: 0.497 to 3.301). In conclusion, the serum levels of fT3, fT4, and TT4 increased but TSH decreased significantly in women with compared without HG, indicating the significant association of HG with GTT.

Curcumin and vitamin E improve hot flashes, lipid profile, and fasting blood glucose without any detrimental effect on the liver and renal function in postmenopausal women: A triple-blind placebo-controlled clinical trial.

We conducted this study to evaluate the efficacy of Curcumin and vitamin E on hot flashes, lipid profile, blood glucose, and hepatic & renal biomarkers. Eighty-four postmenopausal women were randomly assigned into three groups to receive one Curcumin 500 milligram, vitamin E 200 IU, or placebo capsules twice/daily/eight weeks. In comparison with placebo, vitamin E significantly decreased the number of hot flashes (P = 0.002), serum triglyceride (P < 0.001), and aspartate aminotransferase (P = 0.007), while it increased high-density lipoprotein cholesterol (P = 0.005). Curcumin decreased significantly fasting blood glucose (P = 0.007), total cholesterol (P = 0.015), and triglyceride (P = 0.007) compared to placebo. We conclude that vitamin E reduced the incidence of hot flashes by nearly one-third of the base amount. It improved serum lipid profile and aspartate aminotransferase. Curcumin ameliorated fasting blood glucose and serum lipid profile.

The effect of nanomicelle curcumin supplementation and Nigella sativa oil on the expression level of miRNA-21, miRNA-422a, and miRNA-503 gene in postmenopausal women with low bone mass density: A randomized, triple-blind, placebo-controlled clinical trial with factorial design.

This study aimed to investigate the effect of nanomicelle curcumin (CUR), Nigella sativa oil (NS), and CUR and NS on the plasma levels of miR-21, miR-422a, and miR-503 expression in postmenopausal women with low bone mass density (BMD). This randomized, triple-blind, placebo-controlled clinical trial with a factorial design was conducted on 120 postmenopausal women from the integrated healthcare system, Tabriz-Iran. The BMD was determined using dual-energy X-ray absorptiometry (DEXA). Women were randomly divided into four groups of 30 participants: (a) CUR (80 mg) and placebo of NS, (b) NS (1,000 mg) and placebo of CUR, (c) CUR (80 mg) and NS (1,000 mg), and (d) both placebos (containing microcrystalline cellulose). The plasma level of miRNA-21, miRNA-422a, and miRNA-503 was determined by qRT-PCR. The expression level of miRNAs at the baseline was similar. At the end of the intervention, only the expression level of miRNA-21 changed statistically significantly between the four groups (p = .037) and between the NS and placebo groups (p = .005). Also, its expression in the two groups receiving NS (p = .037) and NS-CUR (p = .043) was significantly increased. NS and NS-CUR supplementation can increase the expression level of miRNA-21 in postmenopausal women with low bone density, and bring perspective to further studies of the target.
