摘要： Microglia are resident immune cells in the central nervous system. During the pathogenesis of Alzheimer’s disease, stimulatory factors continuously act on the microglia causing abnormal activation and unbalanced phenotypic changes;these events have become a significant and promising area of research. In this review, we summarize the effects of microglial polarization and crosstalk with other cells in the central nervous system in the treatment of Alzheimer’s disease. Our literature search found that phenotypic changes occur continuously in Alzheimer’s disease and that microglia exhibit extensive crosstalk with astrocytes, oligodendrocytes, neurons, and penetrated peripheral innate immune cells via specific signaling pathways and cytokines. Collectively, unlike previous efforts to modulate microglial phenotypes at a single level, targeting the phenotypes of microglia and the crosstalk with other cells in the central nervous system may be more effective in reducing inflammation in the central nervous system in Alzheimer’s disease. This would establish a theoretical basis for reducing neuronal death from central nervous system inflammation and provide an appropriate environment to promote neuronal regeneration in the treatment of Alzheimer’s disease.

摘要： BACKGROUND The number of elderly individuals with diabetes is dramatically increasing.Diabetes is a long-term condition and a noncommunicable disease and requires intensive daily self-management.Understanding of self-management from the patients’perspectives is important to nurses,healthcare providers,and researchers and benefits people by improving their self-management skills.AIM To examine and synthesize qualitative studies that explore the experiences of elderly people in self-managing diabetes.METHODS Electronic databases were searched,including MEDLINE,CINAH,PsycINFO,PubMed,CNKI,and WANFADATA.Relevant research was identified by manually searching reference lists and gray literature.Only English and Chinese publications were included.The Critical Appraisal Skills Program was used to assess the quality of the research.The Confidence in the Evidence from Reviews of Qualitative research approach was used to assess the confidence of the findings.RESULTS A total of 10 qualitative studies were included,and content analysis was performed.Five themes were identified:The need for knowledge about diabetes care,support systems,functional decline,attitudes toward diabetes,and healthy lifestyle challenges.CONCLUSION This present review provides a deep and broad understanding of the experiences in the self-management of diabetes and can be valuable to nursing practice and provide recommendations for future research.

摘要： Severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)infection has spread throughout the world,which becomes a global public health emergency.Undernourishment prolongs its convalescence and has an adverse effect on its prognosis,especially in diabetic patients.The purpose of this study was to evaluate the prevalence and characteristics of undernourishment and to determine how it is related to the prognostic outcomes in the diabetic patients with coronavirus disease 2019(COVID-19).A retrospective,multicenter study was conducted in 85 diabetic COVID-19 patients from three hospitals in Hubei Province.All patients were assessed using the European Nutritional Risk Screening 2002(NRS-2002)and other nutritional assessments when admitted.Of them,35(41.18%)were at risk of malnutrition(NRS score≥3).Severe COVID-19 patients had a significantly lower level of serum albumin and prealbumin and higher NRS score than non-severe patients.Multivariate logistic regression analysis showed that serum prealbumin and NRS score increased the likelihood of progression into severe status(P<0.05).Meanwhile,single factor and multivariate analysis determined that grade of illness severity was an independent predictor for malnutrition.Furthermore,prealbumin and NRS score could well predict severe status for COVID-19 patients.The malnutrition group(NRS score≥3)had more severe illness than the normal nutritional(NRS score<3)group(P<0.001),and had a longer length of in-hospital stay and higher mortality.Malnutrition is highly prevalent among COVID-19 patients with diabetes.It is associated with severely ill status and poor prognosis.Evaluation of nutritional status should be strengthened,especially the indicators of NRS-2002 and the level of serum prealbumin.

摘要： BACKGROUND Type 1 diabetes(T1D)incidence varies substantially between countries/territories,with most studies indicating increasing incidence.In Western Pacific region(WPR),reported rates are much lower than European-origin populations.In contrast,there are reports of substantial numbers of young people with type 2 diabetes(T2D).A deeper understanding of T1D and T2D in the WPR may illuminate factors important in pathogenesis of these conditions.Furthermore,with varying resources and funding for diabetes treatment in this region,there is a need to more clearly determine the current burden of disease and also any gaps in knowledge.AIM To compile and summarise published epidemiologic and phenotypic data on childhood diabetes in non-European populations in and from WPR.METHODS Research articles were systematically searched from PubMed(MEDLINE),Embase,Cochrane library,and gray literature.Primary outcome measures were incidence and prevalence,with secondary measures including phenotypic descriptions of diabetes,including diabetes type categorization,presence of diabetic ketoacidosis(DKA)at onset,autoantibody positivity,Cpeptide levels,and human leucocyte antigen phenotype.Extracted data were collected using a customized template.Three hundred and thirty relevant records were identified from 16 countries/territories,with analysis conducted on 265(80.3%)records published from the year 2000.RESULTS T1D incidence ranged from<1-7.3/100000 individuals/year,rates were highest in emigrant/mixed populations and lowest in South-East Asia,with most countries/territories(71.4%)having no data since 1999.Incidence was increasing in all six countries/territories with data(annual increases 0.5%-14.2%,highest in China).Peak age-of-onset was 10-14 years,with a female case excess.Rate of DKA at onset varied from 19.3%-70%.Pancreatic autoantibodies at diagnosis were similar to European-origin populations,with glutamic acid decarboxylase-65 autoantibody frequency of 44.1%-64.5%,insulinoma-associated 2 autoantibody 43.5%-70.7%,and zinc transporter-8 autoantibody frequency 54.3%(one study).Fulminant T1D also occurs.T2D was not uncommon,with incidence in Japan and one Chinese study exceeding T1D rates.Monogenic forms also occurred in a number of countries.CONCLUSION T1D is less common,but generally has a classic phenotype.Some countries/territories have rapidly increasing incidence.T2D is relatively common.Registries and studies are needed to fill many information gaps.

摘要： Coronavirus disease 2019(COVID-19)caused by severe acute respiratory syndrome coronavirus-2 has become a worldwide public health crisis.Studies have demonstrated that diabetes and dyslipidaemia are common comorbidities and could be high-risk factors for severe COVID-19.Vitamin D,a group of fatsoluble compounds responsible for intestinal absorption of calcium,magnesium,and phosphate,has been widely used as a dietary supplement for the prevention and treatment of numerous diseases,including infectious and non-infectious diseases,due to its high cost-effectiveness;safety;tolerability;and anti-thrombotic,anti-inflammatory,antiviral,and immunomodulatory properties.In this letter to the editor,we mainly discuss the potential role of vitamin D in patients with diabetes,dyslipidaemia,and COVID-19.

摘要： Polycystic ovary syndrome(PCOS)often coexists with a wide spectrum of dysglycemic conditions,ranging from impaired glucose tolerance to type 2 diabetes mellitus(T2D),which occur to a greater extent compared to healthy body mass index-matched women.This concurrence of disorders is mainly attributed to common pathogenetic pathways linking the two entities,such as insulin resistance.However,due to methodological flaws in the available studies and the multifaceted nature of the syndrome,there has been substantial controversy as to the exact association between T2D and PCOS which has not yet been elucidated.The aim of this review is to present the best available evidence regarding the epidemiology of dysglycemia in PCOS,the unique pathophysiological mechanisms underlying the progression of dysglycemia,the most appropriate methods for assessing glycemic status and the risk factors for T2D development in this population,as well as T2D risk after transition to menopause.Proposals for application of a holistic approach to enable optimal management of T2D risk in PCOS are also provided.Specifically,adoption of a healthy lifestyle with adherence to improved dietary patterns,such the Mediterranean diet,avoidance of consumption of endocrine-disrupting foods and beverages,regular exercise,and the effect of certain medications,such as metformin and glucagon-like peptide 1 receptor agonists,are discussed.Furthermore,the maintenance of a healthy weight is highlighted as a key factor in achievement of a significant reduction of T2D risk in women with PCOS.

摘要： BACKGROUND When combined with vanadium salts,catecholamines strongly activate glucose uptake in rat and mouse adipocytes.AIM To test whether catecholamines activate glucose transport in human adipocytes.METHODS The uptake of 2-deoxyglucose(2-DG)was measured in adipocytes isolated from pieces of abdominal subcutaneous tissue removed from women undergoing reconstructive surgery.Pharmacological approaches with amine oxidase inhibitors,adrenoreceptor agonists and antioxidants were performed to unravel the mechanisms of action of noradrenaline or adrenaline(also named epinephrine).RESULTS In human adipocytes,45-min incubation with 100μmol/L adrenaline or noradrenaline activated 2-DG uptake up to more than one-third of the maximal response to insulin.This stimulation was not reproduced with millimolar doses of dopamine or serotonin and was not enhanced by addition of vanadate to the incubation medium.Among various natural amines and adrenergic agonists tested,no other molecule was more efficient than adrenaline and noradrenaline in stimulating 2-DG uptake.The effect of the catecholamines was not impaired by pargyline and semicarbazide,contrarily to that of benzylamine or methylamine,which are recognized substrates of semicarbazide-sensitive amine oxidase.Hydrogen peroxide at 1 mmol/L activated hexose uptake but not pyrocatechol or benzoquinone,and only the former was potentiated by vanadate.Catalase and the phosphoinositide 3-kinase inhibitor wortmannin inhibited adrenaline-induced activation of 2-DG uptake.CONCLUSION High doses of catecholamines exert insulin-like actions on glucose transport in human adipocytes.At submillimolar doses,vanadium did not enhance this catecholamine activation of glucose transport.Consequently,this dismantles our previous suggestion to combine the metal ion with catecholamines to improve the benefit/risk ratio of vanadium-based antidiabetic approaches.

摘要： Background:Diabetes and hypertension have been identified as risk factors for HCV complications in previous studies.This has sparked the interest in the field of prevention by identifying at-risk individuals and increasing investments for screening among pharmacists.The aim of this study was to screen for risk factors,including age,gender,BMI,hypertension,diabetes,and obesity,in Egyptian patients with HCV Methods:A prospective cross-sectional study was carried out from September 2018 to February 2019,with a total of 1,959 medical records collected.By comparing the patients'characteristics,variables related to metabolic risk,and body composition measurements,regression models have been established to determine any confounding factors.Results:The prevalence of HCV antibody was 41.0%in men and 59.0%in women.Among the variables included in the regression analysis,age,BMI,and uncontrolled hypertension were found to have statistically significant associations with diabetes in HCV positive cases(p40 years old with high BMI were found to have significant associations with both,diabetes and hypertension(p40,and DM(p<0.001).Conclusion:HCV infection and metabolic disorders have a closed cycle relationship.Reducing the complications of DM has a promising prospective of limiting the complications of HCV .
