Diabetes is one of the most common chronic diseases in China, with a high prevalence rate of 12.8%. Diabetes is divided into type 1 diabetes and type 2 diabetes. Monitoring blood glucose levels is also very important to keep the blood glucose level at a normal level. The aim of this study was to evaluate the effectiveness of continuous glucose monitoring (CGM) and self-monitoring of blood glucose (SMBG) in maintaining glycaemic control among patients with type 1 diabetes. This study is a systematic review and meta-analysis of fifteen studies Results showed that the level of haemoglobin A1C in the CGM group decreased by 2.69 mmol/mol compared with the SMBG group. Furthermore, compared with the SMBG group, the risk of severe hypoglycaemic events in the CGM group was reduced by 48%, which is inconsistent with the results of other meta-analyses. Finally, there was no difference between the two methods in the incidence of diabetic ketoacidosis [is a serious complication of diabetes that can be life-threatening]. Authors conclude that for patients with type 1 diabetes, CGM is a better method for monitoring blood glucose.
Abstract
Objective: To evaluate the effectiveness of different glucose monitoring methods on blood glucose control and the incidence of adverse events among patients with type 1 diabetes mellitus. Methods: Using the method of literature review, the databases PubMed, Cochrane, and Embase were retrieved to obtain relevant research literature, and the selected studies were analyzed and evaluated. This study used Cochrane software RevMan5.4 to statistically analyze all the data. Results: A total of 15 studies were included in this study, including 10 randomized controlled trials and 5 crossover design trials, with a total of 2071 patients. Meta-analysis results showed that continuous blood glucose monitoring (CGM) could significantly reduce the HbA1c level of patients, weighted mean difference (WMD) = -2.69, 95% confidence interval (CI) (-4.25, -1.14), and P < 0.001 compared with self-monitoring of blood glucose (SMBG). Meanwhile, the incidence of severe hypoglycemia in the CGM group was significantly decreased, risk ratio (RR) = 0.52, 95% CI 0.35-0.77, and P = 0.001. However, there was no statistical difference in the probability of diabetic ketoacidosis between CGM and SMBG groups, RR = 1.34, 95% CI 0.57-3.15, and P = 0.5. Conclusion: Continuous blood glucose monitoring is associated with lower blood glucose levels than the traditional blood glucose self-test method.

The human gut, or intestines, are populated with commensal bacteria which live in harmony with us and support various biological functions. The main role of the gut microbiota is to maintain the homeostasis of our immune system. It does this by maintaining the integrity of the intestinal lining and helping with digestive processes, production, and absorption of nutrients, and harvesting of immune cells. Our gut microbiome develops throughout infancy and confers benefits in adulthood and so any disruption to its development may impact on health. An imbalance between these helpful bacteria and more harmful pathogenic bacteria, which are also present in smaller amounts, is called dysbiosis and is a common factor in many autoimmune conditions. Autoimmune conditions are characterised by an over-active immune system where immune cells attack our own body. Imbalances in gut microbiota are also common, and diet is thought to be a key factor alongside other genetic and environmental factors. Evidence suggests that long-term dysbiosis may trigger autoimmune disease, amplify disease progression or both, as seen in studies on Arthritis, Lupus, Inflammatory bowel disease. The gut microbiota can be partially restored and supported with antimicrobial interventions, prebiotics, and selective probiotics. The review concludes that therapies targeting the gut microbiota may be effective in the future prevention or treatment of autoimmune diseases.
Abstract
The human gut-resident commensal microbiota is a unique ecosystem associated with various bodily functions, especially immunity. Gut microbiota dysbiosis plays a crucial role in autoimmune disease pathogenesis as well as in bowel-related diseases. However, the role of the gut microbiota, which causes or influences systemic immunity in autoimmune diseases, remains elusive. Aryl hydrocarbon receptor, a ligand-activated transcription factor, is a master moderator of host-microbiota interactions because it shapes the immune system and impacts host metabolism. In addition, treatment optimization while minimizing potential adverse effects in autoimmune diseases remains essential, and modulation of the gut microbiota constitutes a potential clinical therapy. Here, we present evidence linking gut microbiota dysbiosis with autoimmune mechanisms involved in disease development to identify future effective approaches based on the gut microbiota for preventing autoimmune diseases.

Metabolic syndrome (MetS) is a complex disease characterised by high blood sugar, raised blood pressure, dyslipidemia and obesity. It is a major contributing factor to chronic disease such as type 2 diabetes and cardiovascular disease. The aim of this study is to review the cause of MetS, understand how it progresses to chronic disease and analyse the efficacy of clinical interventions in reducing this progression. According to the existing research, this study found insulin sensitivity to be a critical aspect of the pathogenesis in MetS. Effective intervention strategies should be aimed at increasing insulin sensitivity. Based on this information, the authors conclude health practitioners should help patients manage energy balance and reduce overall inflammatory markers to best control the progression of MetS.
Abstract
The growing prevalence of metabolic syndrome (MetS) in the U.S. and even worldwide is becoming a serious health problem and economic burden. MetS has become a crucial risk factor for the development of type 2 diabetes mellitus (T2D) and cardiovascular diseases (CVD). The rising rates of CVD and diabetes, which are the two leading causes of death, simultaneously exist. To prevent the progression of MetS to diabetes and CVD, we have to understand how MetS occurs and how it progresses. Too many causative factors interact with each other, making the investigation and treatment of metabolic syndrome a very complex issue. Recently, a number of studies were conducted to investigate mechanisms and interventions of MetS, from different aspects. In this review, the proposed and demonstrated mechanisms of MetS pathogenesis are discussed and summarized. More importantly, different interventions are discussed, so that health practitioners can have a better understanding of the most recent research progress and have available references for their daily practice.

Plain language summary
This mechanism study examines the role of quercetin at inhibiting influenza infection. Influenza A viruses (IAVs) are responsible for seasonal global pandemics and mortality, and genetic variations make it almost impossible to develop timely vaccines. Novel therapeutic strategies are anti-influenza agents are therefore of great interest. Two classes of anti-influenza drugs are widely used to inhibit viral entry and development, with varying side effects reported. Targeting viral entry and suppression of the infection at its early stage is an attractive therapeutic strategy. Quercetin is known to have anti-viral effects, alongside antioxidant, antibacterial and antiproliferation properties. Cells were infected with different influenza strains and exposed to quercetin, and the cytopathic effect and inhibition rates were measured at intervals. The results showed quercetin reduced transcription in influenza-virus-infected cells in a dose-dependent manner. This implies that quercetin’s mechanism of action may inhibit influenza in the early stage of viral attachment. Additional experiments found that quercetin directly targets the viral hemagglutinin protein particles rather than the host cells. The study concludes that quercetin possesses interesting anti-influenza activities which could be developed as a future therapeutic option for the therapy and prophylaxis of IAV infection.
Abstract
Influenza A viruses (IAVs) cause seasonal pandemics and epidemics with high morbidity and mortality, which calls for effective anti-IAV agents. The glycoprotein hemagglutinin of influenza virus plays a crucial role in the initial stage of virus infection, making it a potential target for anti-influenza therapeutics development. Here we found that quercetin inhibited influenza infection with a wide spectrum of strains, including A/Puerto Rico/8/34 (H1N1), A/FM-1/47/1 (H1N1), and A/Aichi/2/68 (H3N2) with half maximal inhibitory concentration (IC50) of 7.756 ± 1.097, 6.225 ± 0.467, and 2.738 ± 1.931 μg/mL, respectively. Mechanism studies identified that quercetin showed interaction with the HA2 subunit. Moreover, quercetin could inhibit the entry of the H5N1 virus using the pseudovirus-based drug screening system. This study indicates that quercetin showing inhibitory activity in the early stage of influenza infection provides a future therapeutic option to develop effective, safe and affordable natural products for the treatment and prophylaxis of IAV infections.
