The effects of ginger supplementation on markers of inflammatory and oxidative stress: A systematic review and meta‐analysis of clinical trials

The present systematic review and meta‐analysis was conducted to investigate the effects of ginger supplementation on markers of inflammatory and oxidative stress. PubMed, Embase, Scopus, and Web of Science were systematically searched to identify relevant clinical trials evaluating the effects of ginger on serum CRP (C‐reactive protein), TNF‐α (tumor necrosis factor‐alpha), IL‐6 (interleukin‐6), PGE2 (prostaglandin E2), TAC (total antioxidant capacity), and MDA (malondialdehyde) from inception up to September 2019. Mean difference and 95% confidence intervals were pooled using a random‐effects model. Potential publication bias was assessed using visual inspection of funnel plot and Egger's weighted regression tests. After excluding irrelevant records, 20 full‐text articles that included 25 separate studies were included to the meta‐analysis. Pooled results of this study indicated a statistically significant effect of ginger on serum CRP, TNF‐α, IL‐6, TAC, and MDA levels following ginger supplementation in compared to the controls. Also, the effects of ginger on serum PGE2 was marginally significant. Moreover, the high heterogeneity was disappeared in subgroup analysis performed by age, duration, dosage, and quality. This current analysis indicates that ginger supplementation has a significant effects on serum inflammatory and oxidative stress markers.     

ETV6 (TEL1) regulates embryonic hematopoiesis in zebrafish

Chromosomal translocations involving fusions of the human ETV6 (TEL1) gene occur frequently in hematologic malignancies. However, a detailed understanding of the normal function of ETV6 remains incomplete. This study has employed zebrafish as a relevant model to investigate the role of ETV6 during embryonic hematopoiesis. Zebrafish possessed a single conserved etv6 ortholog that was expressed from 12 hpf in the lateral plate mesoderm, and later in hematopoietic, vascular and other tissues. Morpholino-mediated gene knockdown of etv6 revealed the complex contribution of this gene toward embryonic hematopoiesis. During primitive hematopoiesis, etv6 knockdown resulted in reduced levels of progenitor cells, erythrocyte and macrophage populations, but increased numbers of incompletely differentiated heterophils. Definitive hematopoiesis was also perturbed, with etv6 knockdown leading to decreased erythrocytes and myeloid cells, but enhanced lymphopoiesis. This study suggests that ETV6 plays a broader and more complex role in early hematopoiesis than previously thought, impacting on the development of multiple lineages.     

Enzymatic antioxidant and lipid peroxidation evaluation in the newly diagnosed breast cancer patients in Iran

Background: Breast cancer is caused by breast tissue malignant cells and it has become one of the main medical concerns with a socio-economic significance especially for women. Among the multiple factors involved in the initiation, progression, and invasion of breast cancer, oxidative stress plays an important role. Antioxidant status, lipid peroxidation, and oxidative stress in newly diagnosed breast cancer patients were determined to find a defined pattern of oxidative stress in these patients. Methods: The malondialdehyde (MDA) levels (as an indicator of lipid peroxidation), glutathione peroxidase (GPX), and superoxide dismutase (SOD) activities of newly diagnosed breast cancer patients (n=38) and controls (n=38) were assessed using blood samples. Results: MDA level and SOD activity were significantly higher in the breast cancer patients compared to the healthy subjects group (p     

Demographics,health literacy and health locus of control beliefs of Australian women who take complementary medicine products during pregnancy and breastfeeding: A cross‐sectional,online, national survey

BackgroundPregnant and breastfeeding women''s use of complementary medicine products (CMPs) is common, and possibly associated with autonomous health care behaviours. However, the health literacy levels and health locus of control (HLOC) beliefs of women who use CMPs in pregnancy and lactation have not been previously assessed in a large Australian sample.AimThe aim of this study is to determine the health literacy levels and HLOC beliefs of women who use CMPs in pregnancy and lactation and determine the types of CMPs used.MethodsA cross‐sectional, national, online survey of Australian pregnant or breastfeeding women aged 18 years and older, and currently using CMPs was conducted.ResultsA total of 810 completed surveys (354 pregnant and 456 breastfeeding women) were analysed. Most had adequate functional health literacy levels (93.3%). Health care practitioners (HCPs) HLOC mean scores were the highest for the sample, followed by Internal HLOC beliefs mean scores. Almost all (n = 809) took at least one dietary supplement, the most popular being pregnancy and breastfeeding multivitamins, iron supplements and probiotics. Use was generally in line with clinical recommendations, except for low rates of iodine supplementation. Herbal medicine use was lower for the total sample (57.3%, n = 464), but significantly higher (p < .0001) for the breastfeeding cohort, with consumers taking one to four herbal medicines each. The most popular herbs were raspberry leaf, ginger, peppermint and chamomile (pregnant respondents) and chamomile, ginger and fenugreek (breastfeeding respondents).ConclusionsRespondents were health literate, with high scores for Internal and HCP HLOC scales, suggesting that they are likely to demonstrate self‐efficacy, positive health behaviours and work well in partnership with HCPs. HCPs can facilitate discussions with pregnant and breastfeeding women using CMPs, while considering women''s health literacy levels, health beliefs and goals.     

Barriers to a healthy lifestyle among obese adolescents: a qualitative study from Iran

Purpose  

Existing data show a rising prevalence of overweight and obesity among Iranian adolescents. The current study investigates adolescents’ perceptions regarding overweight/obesity and explores barriers to a healthy life style among Iranian adolescents.
