Traditionally, there are some medicinal plants believed to treat diabetes, as they have been proven in research studies to possess antidiabetic properties, such as improved insulin sensitivity and hypoglycemic activities, due to their high level of phenolic compounds, flavonoids, terpenoids, alkaloids, and glycosides. We conducted a systematic review to identify potential medicinal plants used during human clinical trials in the Association of Southeast Asian Nation (ASEAN) countries on prediabetic or type 2 diabetic individuals and to potentially identify any bioactive compounds involved in effectively treating symptoms of diabetes such as lowering of blood glucose. A total of 1209 reference titles were retrieved from four selected databases (Science Direct, Scopus, Springer Link, and PubMed) and only three met the inclusion criteria. Upon evaluation of the selected articles, four medicinal plants were identified: turmeric (Curcuma longa), garlic (Allium sativum L.), bitter melon (Momordica charantia), and Rosella flower (Hibiscus sabdariffa L.). Of these, only the bitter melon study did not show any significant change in the blood glucose of participants after intervention. This review demonstrates the limitations in published articles of human clinical trials for medicinal plants’ intervention for diabetes. Upon further investigations on the four identified medicinal plants included in the animal studies, the findings showed positive effects in the management of diabetes, such as hyperglycemia. Hence, further testing and standardization of the methods in the studies can be suggested for human clinical trials for reliable data collections such as methods of extract preparation, duration of intervention, and conditions set for the study design.

Background: Among non-communicable diseases, cardiovascular diseases (CVDs) are the leading cause of mortality and morbidity in global communities. By 2030, CVD-related deaths are projected to reach a global rise of 25 million. Obesity, smoking, alcohol, hyperlipidemia, hypertension, and hyperhomocysteinemia are several known risk factors for CVDs. Elevated homocysteine is tightly related to CVDs through multiple mechanisms, including inflammation of the vascular endothelium. The strategies for appropriate management of CVDs are constantly evolving; medicinal plants have received remarkable attention in recent researches, since these natural products have promising effects on the prevention and treatment of various chronic diseases. The effects of nutraceuticals and herbal products on CVD/dyslipidemia have been previously studied. However, to our knowledge, the association between herbal bioactive compounds and homocysteine has not been reviewed in details. Thus, the main objective of this study is to review the efficacy of bioactive natural compounds on homocysteine levels according to clinical trials and animal studies. Results: Based on animal studies, black and green tea, cinnamon, resveratrol, curcumin, garlic extract, ginger, and soy significantly reduced the homocysteine levels. According to the clinical trials, curcumin and resveratrol showed favorable effects on serum homocysteine. In conclusion, this review highlighted the beneficial effects of medicinal plants as natural, inexpensive, and accessible agents on homocysteine levels based on animal studies. Nevertheless, the results of the clinical trials were not uniform, suggesting that more well-designed trials are warranted.

Urethral Reconstruction

The purpose of this article was to perform a systematic review of the recent literature on urethral tissue engineering. A total of 31 articles describing the use of tissue engineering for urethra reconstruction were included. The obtained results were discussed in three groups: cells, scaffolds, and clinical results of urethral reconstructions using these components. Stem cells of different origin were used in many experimental studies, but only autologous urothelial cells, fibroblasts, and keratinocytes were applied in clinical trials. Natural and synthetic scaffolds were studied in the context of urethral tissue engineering. The main advantage of synthetic ones is the fact that they can be obtained in unlimited amount and modified by different techniques, but scaffolds of natural origin normally contain chemical groups and bioactive proteins which increase the cell attachment and may promote the cell proliferation and differentiation. The most promising are smart scaffolds delivering different bioactive molecules or those that can be tubularized. In two clinical trials, only onlay-fashioned transplants were used for urethral reconstruction. However, the very promising results were obtained from animal studies where tubularized scaffolds, both non-seeded and cell-seeded, were applied. Impact statement The main goal of this article was to perform a systematic review of the recent literature on urethral tissue engineering. It summarizes the most recent information about cells, seeded or non-seeded scaffolds and clinical application with respect to regeneration of urethra.

Abstract Objectives The present systematic review and meta-analysis investigates the effectiveness of S. officinalis leaves in management of dyslipidemia of chronic disease. Dyslipidemia is one of the main indicators of cardiovascular disease (CVD). It is typically characterized by elevated levels of total cholesterol (TC), low-density lipoprotein cholesterol (LDL) and triglyceride (TG) along with reduction of high-density lipoprotein cholesterol (HDL) in blood. The handling of dyslipidemia is a crucial factor in the general control of the cardiovascular risk in individuals suffering from diseases such as diabetes, CVD or hypertension. Plant foods have played an important role in chronic disease management. S. officinalis leaves (sage) have been identified as improving glucose homeostasis and serum lipids in animal and human models. Methods PubMed, FSTA, Web of Science, CINAHEL and MEDLINE databases were searched using keywords (“Serum lipids” OR triglyceride* OR cholesterol* OR “LDL” OR “HDL” OR dyslipidemia) AND (sage or "Salvia officinalis") up to January 2019. Review articles, animal studies, non-trial, non-specific related plants, and articles which did not examine lipid profiles were included in the exclusion criteria. Articles that met the inclusion criteria included effects of administration of Salvia officinalis on serum lipid in clinical trials. All statistical calculations were performed using SAS software version 9.2 (SAS, Cary NC, USA). Results From 243 studies, four of the trials met the selection criteria of the meta-analysis. Salvia officinalis significantly improved serum lipids. The estimated value for TC was −52.64 mg/dl, 95% CI: −71.0505 to −34.23, P = 0.0001 and LDL −23.28 mg/dl, 95% CI: −40.07 to −6.48, P = 0.006. Moreover, TG was −74.98 mg/dl, 95% CI: −129.16 to −20.8190, P = 0.006 and HDL-C at 6.3424 mg/dl, 95% CI: 1.58 to 11.1033, P = 0.009) was significantly improved after Salvia officinalis administration Conclusions Although the systematic review and meta-analysis investigation involved few studies it revealed promising efficiency of Salvia officinalis on improving the serum lipids in clinical trials and suggested that Salvia officinalis can be an appropriate plant food to manage dyslipidemia of chronic diseases.

Background: Diabetes mellitus is a metabolic disorder associated with relative or absolute insulin deficiency or resistance, characterized by hyperglycemia. Modern prescriptions such as pioglitazone have better therapeutic potential, but its side effects and financial burden for developing countries have motivated the researchers to find alternative natural drugs to compete hyperglycemia in patients with diabetes. The present study was conducted to explore the therapeutic potential of selected medicinal plants for the treatment of diabetes as an alternative to allopathic medicines. Method: In present study, hydroalcoholic extracts of Curcuma longa, Lavandula stoechas, Aegle marmelos, and Glycyrrhiza glabra and their polyherbal preparation (PHP) as compound drug were investigated for their antihyperglycemic potential in alloxan-induced diabetic mice. The study subjects (mice) were divided into different groups as normal control, diabetic control, pioglitazone treated (standard drug), test groups (plant extract treated 50, 100, and 150 mg/kg body weight), and PHP-treated group. Blood glucose concentration of all the study animals was determined by Glucose strip test. Qualitative phytochemical analysis of all the plant extracts was also performed following standard methods. Result: It was investigated that treatment of alloxan-induced diabetic mice with hydroalcoholic extracts of studied medicinal plants showed significant ( P < .05) effects on fasting blood glucose levels (from baseline to normal range) in a manner comparable to that of the reference drug, pioglitazone (1 mg/kg body weight intraperitoneal). The tested plant extracts significantly ( P < .05) reduced the glucose concentration in blood of diabetes-induced mice in a dose-dependent manner. Conclusion: It could be concluded that studied medicinal plants have antihyperglycemic activity. The study findings favor the use of traditional herbal medicinal practices for the management of diabetes that might due to the presence of bioactive phytoconstituents in plants. However, larger studies are required to identify, isolate, and characterize the bioactive phytoconstituents responsible for antihyperglycemic activity of studied medicinal plants.

AbstractThe gut–brain axis has received considerable attention in recent years, and the “psychobiotics” concept indicates that probiotics have a potential positive effect on cognitive function. Therefore, the aim of this study was to quantitatively evaluate the influence of probiotics on cognitive function. We conducted a random-e?ects meta-analysis of 7 controlled clinical trials and 11 animals studies to evaluate the e?ects of probiotics on cognitive function. Probiotics supplementation enhanced cognitive function in both human (0.24 [0.05–0.42]; I2 = 0%) and animal studies (0.90 [0.47–1.34]; I2 = 74%). Subgroup analyses indicated that the effects of probiotics on cognitively impaired individuals (0.25 [0.05–0.45]; I2 = 0%) were greater than those on healthy ones (0.15 [−0.30 to 0.60]; I2 = 0%). Furthermore, compared with a multiple-probiotic supplement, one strain of probiotic was more effective in humans. The meta-analysis provided some suggestions for probiotics intervention and tended to support a customized approach for different individuals to ameliorate cognitive disorders. Future additional clinical trials are necessary to evaluate therapeutic effect and influencing factors.

Glycemic Markers

Background: Although the results were conflicting, the Paleolithic diet (PD) was proposed to be effective in improvement of metabolic status. We aimed to conduct a systematic review and meta-analysis on the randomized controlled clinical trials (RCTs) evaluating the effects of PD on glycemic markers. Methods: Online databases such as PubMed, Scopus, Web of Science, and Google Scholar were searched up to December 2017 without any restrictions. The weighted mean difference (WMD) was also calculated using random effects model. Results: Eventually, eight good quality studies were included in the present systematic review and meta-analysis. The pooled analysis showed that although adherence to the PD led to reduction of fasting blood glucose (FBG) concentrations, it was no statistically significant (WMD = -0.31, 95% CI: -0.70, 0.07, P = 0.11). Moreover, compared with the control diets, the PD consumption did not significantly affect other glycemic markers such as 2-h post-prandial blood glucose (2h PBG), insulin, homeostasis model assessment for insulin resistance (HOMA-IR), and Hemoglobin A1c (HbA1c). Conclusions: Adherence to the PD had no significant effect on the glycemic markers, but reduction was observed in FBG levels.
