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 Coronavirus pandemic (Covid-19) has infected millions of people worldwide and there is evidence that it affects many systems in the human body. This rapid review summarises the current evidence on short-term negative health outcomes of Covid-19. It also assesses the risk of potential long-term negative effects by looking at data from the other coronaviruses; Middle East Respiratory Syndrome (MERS) and Severe Acute Respiratory Syndrome (SARS). The burden for caring for Covid-19 survivors is likely to be huge and so policy makers need suitable data to put the appropriate care strategies in place. The review is divided into sections as per body system affected: Immune, respiratory, cardiovascular, gastrointestinal, hepatic and renal, neurological, dermatological, mental health, pregnancy and prenatal exposure. The evidence (short-term and long-term) is then reviewed by experts in those fields. Further large-scale studies are needed to monitor the adverse effects and to measure the long-term health consequences.
Abstract
The coronavirus disease 2019 (COVID-19) pandemic has resulted in millions of patients infected worldwide and indirectly affecting even more individuals through disruption of daily living. Long-term adverse outcomes have been reported with similar diseases from other coronaviruses, namely Middle East Respiratory Syndrome (MERS) and Severe Acute Respiratory Syndrome (SARS). Emerging evidence suggests that COVID-19 adversely affects different systems in the human body. This review summarizes the current evidence on the short-term adverse health outcomes and assesses the risk of potential long-term adverse outcomes of COVID-19. Major adverse outcomes were found to affect different body systems: immune system (including but not limited to Guillain-Barré syndrome and paediatric inflammatory multisystem syndrome), respiratory system (lung fibrosis and pulmonary thromboembolism), cardiovascular system (cardiomyopathy and coagulopathy), neurological system (sensory dysfunction and stroke), as well as cutaneous and gastrointestinal manifestations, impaired hepatic and renal function. Mental health in patients with COVID-19 was also found to be adversely affected. The burden of caring for COVID-19 survivors is likely to be huge. Therefore, it is important for policy makers to develop comprehensive strategies in providing resources and capacity in the healthcare system. Future epidemiological studies are needed to further investigate the long-term impact on COVID-19 survivors.

Plain language summary
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
Respiratory tract infections (RTIs) are a leading cause of morbidity and mortality among children worldwide. Probiotics are thought to be able to balance the gut microbiota and interact with the immune system, which may promote resistance against pathogens. There are conflicting results from studies investigating the effect of probiotics on RTI infection. The aim of this systematic review and meta-analysis was to provide the latest and convincing evidence of the effect of probiotic consumption on RTIs in children. 32 studies were included in the qualitative analysis, and 23 in the quantitative meta-analysis. All trials were randomised, double-blinded, and placebo-controlled. Probiotic supplementation had a significant effect on the reduction of number of subjects having at least 1 respiratory symptom episode, on the number of days the children were ill and the number of days absent from day care/school. There was no significant statistical difference of illness episode duration. There was statistical heterogeneity among the trials, and subgroup analysis did not highlight the source of this. It was noted, however, that the probiotic strain, the duration of regimens, administration forms, doses, and follow-up times differed across the included studies, as did the age of children. The authors conclude that probiotic consumption may decrease the incidence and illness duration of RTIs, and that further research is needed to establish optimal probiotic strains, dosing, administration form, time of intervention, and long-time follow-up.
Abstract
BACKGROUND Respiratory tract infections (RTIs) represent one of the main health problems in children. Probiotics are viable bacteria that colonize the intestine and affect the host intestinal microbial balance. Accumulating evidence suggests that probiotic consumption may decrease the incidence of or modify RTIs. The authors systematically reviewed data from randomized controlled trials (RCTs) to investigate the effect of probiotic consumption on RTIs in children. METHODS MEDLINE/PubMed, Embase, Cochrane Library, and Web of Science were systematically searched for RCTs regarding the effect of probiotics on RTIs in children. The outcomes included number of children experienced with at least 1 RTI episode, duration of illness episodes, days of illness per subject, and school/day care absenteeism due to infection. A random-effects model was used to calculate pooled relative risks, or mean difference (MD) with the corresponding 95% confidence interval (CI). RESULTS A total of 23 trials involving 6269 children were eligible for inclusion in the systematic review. None of the trials showed a high risk of bias. The quality of the evidence of outcomes was moderate. The age range of subjects was from newborn to 18 years. The results of meta-analysis showed that probiotic consumption significantly decreased the number of subjects having at least 1 RTI episode (17 RCTs, 4513 children, relative risk 0.89, 95% CI 0.82-0.96, P = 0.004). Children supplemented with probiotics had fewer numbers of days of RTIs per person compared with children who had taken a placebo (6 RCTs, 2067 children, MD -0.16, 95% CI -0.29 to 0.02, P = 0.03), and had fewer numbers of days absent from day care/school (8 RCTs, 1499 children, MD -0.94, 95% CI -1.72 to -0.15, P = 0.02). However, there was no statistically significant difference of illness episode duration between probiotic intervention group and placebo group (9 RCTs, 2817 children, MD -0.60, 95% CI -1.49 to 0.30, P = 0.19). CONCLUSION Based on the available data and taking into account the safety profile of RCTs, probiotic consumption appears to be a feasible way to decrease the incidence of RTIs in children.

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.
