Pre-diabetes, which is typically defined as blood glucose concentrations higher than normal but lower than thediabetes threshold, is a high-risk state for diabetes and cardiovascular disease development. As such, it represents three groups of individuals: Those with impaired fasting glucose(IFG), those with impaired glucose tolerance(IGT) and those with a glycated haemoglobin(HbA1c) between 39-46 mmol/mol. Several clinical trials have shown the important role of IFG, IGT and HbA1c -pre-diabetes as predictive tools for the risk of developing type 2 diabetes. Moreover, with regard to cardiovascular disease, pre-diabetes is associated with more advanced vascular damage compared with normoglycaemia, independently of confounding factors. In view of these observations, diagnosis of pre-diabetes is mandatory to prevent or delay the development of the disease and its complications; however, a number of previous studies reported that the concordance between pre-diabetes diagnoses made by IFG, IGT or HbA1c is scarce and there are conflicting data as to which of these methods best predicts cardiovascular disease. This review highlights recent studies and cur-rent controversies in the field. In consideration of the expected increased use of HbA1c as a screening tool to identify individuals with alteration of glycaemic homeo-stasis, we focused on the evidence regarding the ability of HbA1c as a diagnostic tool for pre-diabetes and as a useful marker in identifying patients who have an increased risk for cardiovascular disease. Finally, we reviewed the current evidence regarding non-traditional glycaemic biomarkers and their use as alternatives to or additions to traditional ones. 展开更多

Objectives: Diagnostics is the first step for the treatment and eradication of infectious microbial diseases. Due to ever evolving pathogens and emerging new diseases, there is an urgent need to identify suitable diagnostic techniques for better management of each disease. The success rate of specific diagnostic technique in any population depends on various factors including type of the microbial pathogen, availability of resources, technical expertise, disease severity and degree of epidemic of disease in the area. One of the important tasks of the policy makers is to identify and implement suitable diagnostic techniques for specific regions based on their specific requirements. In this review we have discussed various techniques available in the literature and their suitability for the target population based on above mentioned criteria. Methods: Diagnostic techniques evaluation of well documented representative microbial diseases;Tuberculosis (bacterial), Malaria (parasitic) and HIV (viral) were included in the study. Identification and collection of information and data was performed focusing on the diagnostic techniques used from the scientific publications from Pubmed, Science Access, Scopus, EMBASE and several regional databases. WHO and CDC database for Tuberculosis, Malaria and HIV were also included. These techniques were compared with respect to the financial resource availability, expertise and management, functional capacity, pathogen virulence and degree of epidemic in the population. Results and Conclusion: In case of Tuberculosis, ELISA and colorimetric techniques are successful in rural and urban communities with 80% - 90% sensitivity. Genotyping and SNP analysis are useful in drug resistant strains. Parasitic disease Malaria also follows the same trend with diagnostic techniques like RDTs being common in both population with fast results and around 90% sensitivity. STD disease like HIV however shows slight different trends due to urgent need of interference in rural epidemics of the disease. Rapid and sensitive immunotechniques like dipsticks and agglutination with almost 100% sensitivity are used in both rural and urban areas. For the confirmation further tests are done like protein Western and NAAT. Advance techniques could be the option for higher epidemic area, drug resistance and disease research, while rapid techniques would be suitable for low income areas and POC facilities. Therefore, suitability of the diagnostic techniques for better management depends not only on the financial resources and assessment skills of a community but sometimes on the disease itself. We have further discussed the technological improvements for specific settings (rural/urban) based on the past research for better management of diseases, which could be implemented for the understanding of understudied and newly emerging diseases. 展开更多

The development of intestinal anastomosis techniques,including hand suturing,stapling,and compression anastomoses,has been a significant advancement in surgical practice.These methods aim to prevent leakage and minimize tissue fibrosis,which can lead to stricture formation.The healing process involves various phases:hemostasis and inflammation,proliferation,and remodeling.Mechanical staplers and sutures can cause inflammation and fibrosis due to the release of profibrotic chemokines.Compression anastomosis devices,including those made of nickel-titanium alloy,offer a minimally invasive option for various surgical challenges and have shown safety and efficacy.However,despite advancements,anastomotic techniques are evaluated based on leakage risk,with complications being a primary concern.Newer devices like Magnamosis use magnetic rings for compression anastomosis,demonstrating greater strength and patency compared to stapling.Magnetic technology is also being explored for other medical treatments.While there are promising results,particularly in animal models,the realworld application in humans is limited,and further research is needed to assess their safety and practicality. 展开更多

BACKGROUND Type 2 diabetes mellitus(T2DM)causes both macrovascular and microvascular complications.However,currently,selection of glycemic measures and their thresholds to diagnose T2DM,and efficacy outcomes in evaluation of anti-diabetic drugs is predominantly informed by the relation of T2DM to microvascular complications.We can be severely mistaken on T2DM by neglecting macrovascular complications which are generally more severe,if they also occur more commonly than microvascular complications.AIM To compare the incidence of major cardiovascular events(MACEs)and severe microvascular complications(SMICs)in T2DM patients.METHODS MEDLINE,EMBASE,and Cochrane Central Register of Controlled Trials were searched from inception to September 2017.Cohort studies or trials of T2DM patients aged 18 years or older that reported incidence of both MACEs and SMICs were included.MACEs were defined as nonfatal myocardial infarction and stroke,and cardiovascular death,while SMICs included serious retinopathy,nephropathy and diabetic disorder.The relative risk(RR)was estimated as the incidence of MACEs divided by that of SMICs in same patients and combined with meta-analysis in a random-effect model.RESULTS Twelve studies with a total of 16 cohorts and 387376 patients were included,and the combined RR was 2.02(95%CI:1.46–2.79).The higher incidence of MACEs remained in various subgroup and sensitivity analyses.CONCLUSION Patients with T2DM are much more likely to develop MACEs than SMICs.By taking more serious consequences and relatively higher incidence into consideration,macrovascular complications deserve more emphasis in developing the diagnostic criteria of T2DM and in evaluating the efficacy of antidiabetic drugs. 展开更多

Uveitis can cause significant visual morbidity and often affects younger adults of working age.Anterior uveitis,or inflammation limited to the anterior chamber(AC),iris,and/or ciliary body comprises the majority of uveitis cases.Current clinical biomarkers and conventional grading scales for intraocular inflammation are mostly subjective and have only a moderate degree of interobserver reliability,and as such they have significant limitations when used in either clinical practice or research related to uveitis.In recent years,novel imaging techniques and applications have emerged that can supplement exam findings to detect subclinical disease,monitor quantitative biomarkers of disease progression or treatment effect,and provide overall a more nuanced understanding of disease entities.The first part of this review discusses automated algorithms for optical coherence tomography(OCT)image processing and analysis as a means to assess and describe intraocular inflammation with higher resolution than that afforded by conventional AC and vitreous cell ordinal grading scales.The second half of the review focuses on anterior segment OCT and OCT angiography(OCTA)in scleritis and iritis,especially with regards to their ability to directly image and characterize the pathologic structures and vasculature underlying these diseases.Finally,we briefly review experimental animal research with promising but more distant human clinical applications,including in vivo molecular microscopy of inflammatory markers and investigation of gold nanoparticles as a potential contrast agent in OCT imaging.Imaging modalities are discussed in the broader context of trends within the field of uveitis towards greater objectivity and quantifiable outcome measures and biomarkers. 展开更多

BACKGROUND Axial and coronal reformations have been a widely used image post-processing protocol for the ordinary multidetector computed tomography(MDCT)examination of patients with small bowel obstruction(SBO) or other abdominal diseases. The diagnostic accuracy of MDCT for assessing SBO is expected to be further improved through the use of multiple post-processing techniques.AIM To systemically evaluate the diagnostic accuracy and efficiency of an optimized protocol using multiple post-processing techniques for MDCT assessment of SBO and secondary bowel ischemia.METHODS This retrospective cross-sectional study included 106 patients with clinically suspected SBO. Two readers applied three protocols to image post-processing and interpretation of patients' MDCT volume data. We compared the three protocols based on time spent, number of images, diagnostic self-confidence,agreement, detection rate, and accuracy of detection of SBO and secondary bowel ischemia.RESULTS Protocol 2 resulted in more time spent and number of images than protocols 1 and 3(P < 0.01), but the results of the two readers using the same protocol were not different(P > 0.05). Using protocol 3, both readers added multiple postprocessing techniques at frequencies of 29.2% and 34.9%, respectively, for obstruction cause, and 32.1% and 30.2%, respectively, for secondary bowel ischemia. Protocols 2 and 3 had higher total detection rates of obstruction cause and secondary bowel ischemia than protocol 1(P < 0.01), but no difference was detected between protocols 2 and 3(P > 0.05). The accuracy, sensitivity,specificity, positive predictive value and negative predictive value of protocols 2 and 3 were superior to those of protocol 1 for evaluating obstruction cause and secondary bowel ischemia.CONCLUSION Our optimized protocol of multiple post-processing techniques can both guarantee efficiency and improve diagnostic accuracy of MDCT for assessing SBO and secondary bowel ischemia. 展开更多

BACKGROUND Gout and seronegative rheumatoid arthritis(SNRA)are two distinct inflammatory joint diseases whose co-occurrence is relatively infrequently reported.Limited information is available regarding the clinical management and prognosis of these combined diseases.CASE SUMMARY A 57-year-old woman with a 20-year history of joint swelling,tenderness,and morning stiffness who was negative for rheumatoid factor and had a normal uric acid level was diagnosed with SNRA.The initial regimen of methotrexate,leflunomide,and celecoxib alleviated her symptoms,except for those associated with the knee.After symptom recurrence after medication cessation,her regimen was updated to include iguratimod,methotrexate,methylprednisolone,and folic acid,but her knee issues persisted.Minimally invasive needle-knife scope therapy revealed proliferating pannus and needle-shaped crystals in the knee,indicating coexistent SNRA and atypical knee gout.After postarthroscopic surgery to remove the synovium and urate crystals,and following a tailored regimen of methotrexate,leflunomide,celecoxib,benzbromarone,and allopurinol,her knee symptoms were significantly alleviated with no recurrence observed over a period of more than one year,indicating successful management of both conditions.CONCLUSION This study reports the case of a patient concurrently afflicted with atypical gout of the knee and SNRA and underscores the significance of minimally invasive joint techniques as effective diagnostic and therapeutic tools in the field of rheumatology and immunology. 展开更多

儿童活动性结核病存在标本获取困难和病原学诊断阳性率低等问题,而利福平耐药实时荧光定量核酸扩增检测技术(Mycobacterium tuberculosis and rifampin-resistant,简称“Xpert”)作为一种快速检测结核分枝杆菌(MTB)和利福平耐药性的方法... 儿童活动性结核病存在标本获取困难和病原学诊断阳性率低等问题,而利福平耐药实时荧光定量核酸扩增检测技术(Mycobacterium tuberculosis and rifampin-resistant,简称“Xpert”)作为一种快速检测结核分枝杆菌(MTB)和利福平耐药性的方法,以较高的敏感度和特异度为结核病的诊断提供了可靠的依据。目前,该方法已广泛应用于痰液或胃液检测,关于粪便样本对诊断肺结核的应用价值基本得到肯定,但肺外结核应用仍需要大量研究验证。笔者就该方法用于检测儿童结核病粪便样本中的MTB进行综述,为Xpert用于儿童粪便检测在临床中的应用提供参考。 展开更多
