Marital Quality-A Neglected Player in the Prevention of Cardiovascular Diseases: A Systematic Review of Longitudinal Studies.

PURPOSE OF REVIEW: Marital quality (MQ) is a psychosocial factor that has been neglected in cardiovascular prevention guidelines, although its association with cardiovascular diseases has been identified in several studies. Therefore, we aim to investigate how MQ either in positive or negative dimensions affect different cardiovascular risk factors and diseases. RECENT FINDINGS: We systematically searched different databases in September 2023 for longitudinal studies conducted to assess the contribution of MQ to well-established cardiovascular risk factors and diseases. Two independent researchers screened studies and carried out data extraction and quality assessment of included ones. From 12,175 potential studies screened, 40 were included. The presence of significant heterogeneity in methodology, follow-up, and subsequent effect estimates made it unfeasible to do a meta-analysis. Despite the variation, most studies found a significant association of negative MQ measures with physical inactivity (2/2), high levels of smoking (4/5) and alcohol (3/3) use, increased metabolic syndrome risk (3/3), elevated type 2 diabetes mellitus (T2DM) risk and poor T2DM management (3/6), elevated cardiovascular disease risk and progression (9/11), increased body weight and obesity risk (2/3), elevated blood pressure and hypertension risk (7/8). Positive MQ measures were mainly associated with improvement in blood pressure control (2/2), reduced T2DM risk and its good management (1/1), reduced body weight and obesity risk (2/2), and increased survival in cardiovascular diseases (4/4). Based on current evidence, MQ seems to play a crucial role in developing established cardiovascular risk factors and diseases and is worth considering in preventive strategies.

Antioxidative and Anti-inflammatory Effects of Plant-derived Hypoglycemic Medicines: An In vivo/In vitro Systematic Review.

BACKGROUND: The activation of oxidative stress and inflammatory conditions has been associated with acceleration in diabetes (DM) onset and complications. Despite various anti-DM medications, there is a growing trend to discover inexpensive and effective treatments with low adverse effects from plants as one of the promising sources for drug development. OBJECTIVE: This study aimed to systematically investigate the simultaneous anti-inflammatory and antioxidant effects of plant-derived hypoglycemic medicines in diabetic experimental models. METHODS: The search terms consisted of "diabetes", "herbal medicine", "antioxidant", "Inflammatory biomarker", and their equivalents among PubMed, Scopus, Web of Science, and Cochrane Library databases up to 17 August 2021. RESULTS: Throughout the search of databases, 201 eligible experimental studies were recorded. The results showed that the most commonly assessed inflammatory and oxidative stress biomarkers were tumor necrosis factor (TNF)-α, interleukin (IL) 6, IL-1ß, IL-10, malondialdehyde (MDA), and nitric oxide (NO). The activity of antioxidant enzymes, including superoxide dismutase (SOD), glutathione (GSH), and catalase (CAT) were assessed in the present review. Among herbal treatments, Trigonella foenum-graecum L., Centella asiatica (L.) Urb., Vitis vinifera L., and Moringa oleifera Lam. were most commonly used for diabetic complications. Due to the dispersion of the treatments, meta-analysis was not applicable. CONCLUSION: Our findings showed that the application of different plant-derived hypoglycemic treatments in animal models improved diabetes and its complications, as well as modulated concomitant inflammatory and oxidative stress biomarkers. These findings suggest that plant-based antidiabetic medicines and food supplements have the potential to manage diabetes and its complications.

The power of Punica granatum: A natural remedy for oxidative stress and inflammation; a narrative review.

ETHNOPHARMACOLOGICAL RELEVANCE: Pomegranate 'Punica granatum' offers multiple health benefits, including managing hypertension, dyslipidemia, hyperglycemia, insulin resistance, and enhancing wound healing and infection resistance, thanks to its potent antioxidant and anti-inflammatory properties. It has been symbolized by life, health, femininity, fecundity, and spirituality. AIM OF THE STUDY: Although laboratory and animal studies have been conducted on the healing effects of pomegranate, there needs to be a comprehensive review on its anti-oxidative and anti-inflammatory effects in chronic disorders. We aim to provide a comprehensive review of these effects based on in-vitro, in-vivo, and clinical studies conducted in managing various disorders. MATERIALS AND METHODS: A comprehensive search of in-vitro, in-vivo, and clinical findings of pomegranate and its derivatives focusing on the highly qualified original studies and systematic reviews are carried out in valid international web databases, including Web of Science, PubMed, Scopus, and Cochrane Library. RESULTS: Relevant studies have demonstrated that pomegranate and its derivatives can modulate the expression and activity of several genes, enzymes, and receptors through influencing oxidative stress and inflammation pathways. Different parts of pomegranate; roots, bark, blossoms, fruits, and leaves contain various bioactive compounds, such as polyphenols, flavonoids, anthocyanins, and ellagitannins, that have preventive and therapeutic effects against many disorders such as cardiovascular diseases, diabetes, neurological diseases, and cancers without any serious adverse effects. CONCLUSIONS: Most recent scientific evidence indicates that all parts of the pomegranate can be helpful in treating a wide range of chronic disorders due to its anti-oxidative and anti-inflammatory activities. Since the safety of pomegranate fruit, juice, and extracts is established, further investigations can be designed by targeting its active antioxidant and anti-inflammatory constituents to discover new drugs.

Theoretical study on efficient HF gas sensing by functionalized, decorated, and doped nanocone strategy.

Hydrogen fluoride (HF) is a highly dangerous and corrosive gas that can cause severe burns and respiratory damage. The density functional theory method (DFT) used to study the interaction between the HF gas and the surface of a carbon nanocone (CNC) doped with gallium atom as a chemical sensor. The results showed that CNC wasn't a good candidate to sense the HF gas and consequently its electrical properties are changed insignificant. To improve the properties of the CNC, several strategies were tried: functionalizing by pyridinol (Pyr) and pyridinol oxide (PyrO), decorated with metals (M = B, Al, and Ga), and doped with element of third group (M = B, Al, and Ga). The obtained data demonstrated that the promising results were obtained by doping the CNC with Ga atom. After full optimization, we achieved one stable configuration between the HF gas and CNC-Ga structure (S15 configuration) with Eads = -19.86 kcal/mol. The electronic properties of the CNC-Ga structure is sensible changed after the HF molecule is adsorbed. According to calculated the energy gap between HOMO and LUMO orbitals of S15 configuration are increased which could be applied a chemical signal. Eventually, one could propose that the CNC-Ga has the ability to act as a Φ-type sensor based on its physical adsorption energy and quick recovery time and doped with gallium atom is a promising strategy.
