Dietary polyphenols and the risk of metabolic syndrome: a systematic review and meta-analysis.

BACKGROUND: Accumulating evidence has suggested that dietary polyphenols may be protective against metabolic syndrome (MetS); however, the available evidence is contradictory. The aim of this meta-analysis was to assess the association between dietary intake of polyphenols and the odds of MetS. METHODS: The PubMed and Scopus databases were systematically searched to obtain eligible studies. The risk of MetS for the highest versus the lowest intakes of total, subclasses and individual polyphenols were examined by pooling odds ratios (OR) and 95% confidence intervals (95%CI) using the random effects model. RESULTS: A total of 14 studies (6 cohort and 8 cross-sectional studies) involving a total of 50,366 participants with 10,879 cases of MetS were included. When various polyphenol compounds were pooled, they were significantly related to a 22% decreased odds of MetS (([5 studies]; OR: 0.78; 95%CI: 0.72-0.85). Higher intakes of total flavonoids (([9 studies]; OR: 0.78; 95%CI: 0.72-0.85), flavan-3-ols (([2 studies]; OR: 0.64; 95%CI: 0.43-0.94), isoflavones (([3 studies]; OR: 0.84; 95%CI: 0.75-0.93), stilbenes (([4 studies]; OR: 0.86; 95%CI: 0.76-0.97), flavones (([2 studies]; OR: 0.79; 95%CI: 0.71-0.89), and quercetin (([2 studies]; OR: 0.63; 95%CI: 0.43-0.93) were also significantly associated with a decreased risk of MetS. The associations were not modified by the age of the participants. No association was found for total polyphenols, phenolic acids, lignans, anthocyanins, and flavonols. CONCLUSION: The results of this meta-analysis supported that higher polyphenol intake can lower the risk of MetS.

Functions of LncRNAs, exosomes derived MSCs and immune regulatory molecules in preeclampsia disease.

Modulatory signaling pathway such as T cell immunoreceptor with Ig and ITIM domains (TIGIT), Cytotoxic T-Lymphocyte Associated Protein 4 (CTLA-4), P53 signaling and TIM (T-cell immunoglobin and mucin domain) are important in normal pregnancy and loss of their functions or dysregulation of related genes can lead to some disorders. Inflammation is a process by which your body's white blood cells and the things they make protect you from infection from outside invaders, such as bacteria and viruses. Some cellular and molecular signaling have been categorized to demonstrate the mechanism that protects tolerance to antigens. lncRNAs significantly impact physiological processes like immunity and metabolism, and are linked to tumors, cardiovascular diseases, nervous system disorders, and nephropathy.In this review article, we summarized recent studies about the role of TIGIT, CTLA-4, P53 and TIM regulatory molecules and reviewed dysregulation of these pathway in diseases.We will also talk about the role of lncRNAs and mesenchymal stem cells.

LncRNA PVT1: as a therapeutic target for breast cancer.

A significant number of women are identified with breast cancer (BC) every year, making it among the most prevalent malignancies and one of the leading causes of mortality globally. Despite significant progress in understanding BC pathogenesis and treatment options, there is still a need to identify new therapeutic targets and develop more effective treatments. LncRNAs have been discovered as biomarkers and a promising target for various cancers, including BC. PVT1 is a particular one of these lncRNAs, and research has indicated that it has a significant impact on the appearance and progression of BC.PVT1 is an attractive therapeutic target for BC due to its role in promoting cancer cell growth, metastasis and invasion. In addition to its potential as a treatment strategy, PVT1 may also have diagnostic value in BC. In this article, we will discuss targeting PVT1 as a treatment strategy for BC.

Diet quality indices and odds of metabolic dysfunction-associated fatty liver disease: a case-control study.

Objectives: There are only limited studies investigating the impact of dietary quality indicators, such as dietary quality index (DQI), dietary diversity score (DDS), and alternative healthy eating index (AHEI), on metabolic dysfunction-associated fatty liver disease (MASLD). Furthermore, these indicators may have different components that could lead to varying results. Therefore, this study aims to assess the nutritional quality indicators and their potential association with MASLD. Methods: The study included 128 recently diagnosed MASLD patients and 256 controls aged between 20 and 60 years. The dietary intake of participants was evaluated using a validated semi-quantitative food frequency questionnaire that consisted of 168 items. In this study, the method used to evaluate dietary diversity was based on five main food groups, specifically bread and grains, vegetables, fruits, meat, and dairy. The AHEI-2010 was computed using data collected from the FFQ. Results: After adjusting for confounders in the fully adjusted model, a significant negative correlation was observed between DDS and the risk of MASLD (OR 0.41, 95% CI 0.20, 0.97). Participants in the top quartile of AHEI had a 76% lower risk of MASLD compared with those in the bottom quartile after controlling for all potential confounders in the fully adjusted model (OR 0.24, 95% CI 0.12, 0.56). Conclusion: The results of our study suggest that there is a significant association between adherence to a high-diversity diet and a reduced likelihood of developing MASLD. Similarly, we observed a similar association between adherence to the AHEI diet and a lower risk of MASLD.

Effectiveness of Breathing Exercises, Foot Reflexology and Massage (BRM) on Maternal and Newborn Outcomes Among Primigravidae in Saudi Arabia: A Randomized Controlled Trial.

BACKGROUND: Labor pain and anxiety are important concerns during labor, especially among the primigravidae. It may increase the duration of labor, increase stress hormones, and affect maternal and new-born related outcomes. This study examined the effectiveness of combined breathing exercises, foot reflexology, and massage (BRM) interventions on labor pain, anxiety, labor duration, stress hormone levels, maternal satisfaction, maternal vital signs, and the new-born's APGAR scores. PARTICIPANTS AND METHODS: This single-blind-parallel randomized controlled trial (RCT) was conducted at the Maternity and Children Hospital (MCH), Makkah, Saudi Arabia, by recruiting primigravidae aged 20 to 35 years, without any medical complications, and who were block-randomized at six-centimeter cervical dilation and stratified by intramuscular pethidine. The intervention is BRM compared to standard care. The labor pain was measured via present behavioral intensity (PBI) and visual analogue scale (VAS), and the anxiety was measured via Anxiety Assessment Scale for Pregnant Women in Labor (AASPWL). The secondary outcomes were duration of labor, maternal stress hormone levels, maternal vital signs, maternal satisfaction, fetal heart rate, and APGAR scores. All outcomes were measured at multiple time-points during and after contraction at baseline, during BRM intervention, at 60, 120, and 180 minutes post-intervention. Generalized linear mixed models were used to estimate the intervention effects over time. RESULTS: A total of 225 participants were randomized for the control (n = 112) and intervention group (113). BRM lowered the labor pain intensity at 60 minutes after intervention during (1.3 vs 3.5, F = 102.5, p < 0.001) and after contraction (0.4 vs 2.4, F = 63.6, p < 0.001) and also lowered anxiety (2.9 vs 4.2, F = 80.4, p < 0.001). BRM correspondingly lowered adrenocorticotropic (ACTH) (133 vs 209 pg/mL, p < 0.001), cortisol (1231 vs 1360 nmol/mL, p = 0.003), and oxytocin (159 vs 121 pg/mL, p < 0.001). It also shortened the labor duration (165 vs 333 minutes, p < 0.001), improved vital signs, which resulted in higher APGAR scores, and increased maternal satisfaction. CONCLUSION: The labor unit management could consider adopting BRM as one of the non-pharmacological analgesia for healthy women in labor. TRIAL REGISTRATION: ISRCTN87414969, registered 3 May 2019.

Impact of estrogen therapy on temporomandibular joints of rats: Histological and hormone analytical study.

OBJECTIVES: This research aims to evaluate the effects of estrogen deficiency and replacement on the TMJ structures of rats. The considerable similarities in the anatomical features of rats and humans make rats a suitable model for human scientific studies. METHODS: A clinical trial was conducted on 18 female Sprague-Dawley rats grouped into three categories. The GI group included 6 female rats labelled as the control group, the GII group consisted of 6 females that received ovariectomies, and the GIII group had 6 ovariectomised females that were injected with estrogen replacement therapy in a science laboratory at King Abdulaziz University. ANOVA and Tukey HSD post hoc tests were used to determine any significant differences between the levels of estrogen among the three groups. RESULTS: The results indicate that some TMJ structures, including the articular disc and condylar cartilaginous layer, were degraded after estrogen deficiency. However, there was a slight improvement in the cartilaginous layer thickness and proliferation of chondroid cells after estrogen replacement therapy. Estrogen level was reduced in the ovariectomized rats, and while estrogen injections increased blood hormone levels, the levels did not reach those of the control group. CONCLUSION: Estrogen deficiency degraded some TMJ structures, and there is only a slight recovery after estrogen replacement therapy.

Effectiveness of breathing exercises, foot reflexology and back massage (BRM) on labour pain, anxiety, duration, satisfaction, stress hormones and newborn outcomes among primigravidae during the first stage of labour in Saudi Arabia: a study protocol for a randomised controlled trial.

INTRODUCTION: Labour pain is among the severest pains primigravidae may experience during pregnancy. Failure to address labour pain and anxiety may lead to abnormal labour. Despite the many complementary non-pharmacological approaches to coping with labour pain, the quality of evidence is low and best approaches are not established. This study protocol describes a proposed investigation of the effects of a combination of breathing exercises, foot reflexology and back massage (BRM) on the labour experiences of primigravidae. METHODS AND ANALYSIS: This randomised controlled trial will involve an intervention group receiving BRM and standard labour care, and a control group receiving only standard labour care. Primigravidae of 26-34 weeks of gestation without chronic diseases or pregnancy-related complications will be recruited from antenatal clinics. Eligible and consenting patients will be randomly allocated to the intervention or the control group stratified by intramuscular pethidine use. The BRM intervention will be delivered by a trained massage therapist. The primary outcomes of labour pain and anxiety will be measured during and after uterine contractions at baseline (cervical dilatation 6 cm) and post BRM hourly for 2 hours. The secondary outcomes include maternal stress hormone (adrenocorticotropic hormone, cortisol and oxytocin) levels, maternal vital signs (V/S), fetal heart rate, labour duration, Apgar scores and maternal satisfaction. The sample size is estimated based on the between-group difference of 0.6 in anxiety scores, 95% power and 5% α error, which yields a required sample size of 154 (77 in each group) accounting for a 20% attrition rate. The between-group and within-group outcome measures will be examined with mixed-effect regression models, time series analyses and paired t-test or equivalent non-parametric tests, respectively.
