Recently studies have shown a connection between periodontal disease and cardiovascular disease, as oxidative stress plays an important role in chronic inflammatory diseases such as periodontal disease and cardiovascular disease. Nuclear factor erythroid 2 - related factor 2 (Nrf2) is the core transcriptional regulator of endogenous antioxidant system and plays a cellular defense role in antioxidant, anti-inflammatory and immune response. Objective To explore Nrf2/antioxidant responsive element (ARE) signaling pathway in periodontitis or periodontitis complicated with atherosclerosis. Method With \"Nuclear Factor Erythroid 2-Related Factor 2 (Nrf2), Periodontitis, Atherosclerosis, Oxidative Stress\" as the search terms, the authors searched related articles published during 2016-2021 in PubMed, CNKI, Science Direct and other databases by computer, and made the following review through screening, induction and summary. Result & Conclusion Nrf2/ARE signaling pathway is one of the important mechanisms connecting chronic periodontitis and atherosclerosis. Nrf2 can slow down the occurrence and development of periodontitis by promoting osteoblast differentiation, inhibiting osteoclast activation, regulating mesenchymal stem cell proliferation, differentiation and apoptosis. However, inhibition of Nrf2/ARE signaling pathway may increase the risk of periodontitis with atherosclerosis by destroying the integrity of vascular endothelium, increasing lipid accumulation and promoting inflammation","PeriodicalId":7179,"journal":{"name":"Advanced Biomedicine","volume":"16 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79646637","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Tens and thousands of people have suffered with COVID-19 in last one and half year. Most people who have suffered with COVID-19 recover completely within a few weeks but majority of patients continue to have varied symptoms after initial recovery. Objective: To assess the prevalence of Post COVID symptoms, to assess requirement of treatment and to make recommendation for Post COVID syndrome care. Methods: Present cross-sectional study was done among patients who recovered from COVID-19 in GIMS Hospital of Kalaburagi district. Mobile numbers of COVID patients were collected from records. Total 100 randomly selected patients were contacted and information regarding post COVID symptoms in between 6 weeks to 12 weeks after recovery from COVID-19 was collected. Result: 87%patients developed one or more post COVID symptoms. Weakness was reported to be most common problem (55%), followed by body ache (26%) and neuropsychiatric symptoms such as difficulty in concentration and insomnia (22%). Every fifth patient reported that symptoms persisted for more than 1 month. Though most of the respondents classified their symptoms as mild and moderate (52.5% and 37.9% respectively), 47% of the symptomatic patients have to take some treatment for these symptoms. Conclusion: Post COVID symptoms are common but usually less severe. Many of patients required conservative management with medications. Many patients required lot of counselling. Almost one in five patients reported that symptoms persisted for more than one month. The results highlight the need for post COVID care for COVID recovered patients.","PeriodicalId":7179,"journal":{"name":"Advanced Biomedicine","volume":"128 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87633728","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, current approaches for exosomal PD-L1 detection are poorly sensitive, laborious, and time-consuming. Here, a new method, named Aptamer-RPA-TMA-Cas13a Assay (ARTCA) is established, which enables exosomal PD-L1 to be detected directly in serum with a lower limit of 10 particles mL−1. Mechanistically, using DNA aptamer specifically binding to exosomal PD-L1, the aptamer is amplified twice by recombinase polymerase amplification (RPA) coupled with transcription-mediated amplification (TMA) and simultaneously the TMA products are detected in real-time with CRISPR/Cas13a system. Utilizing ARTCA, PD-L1 levels in circulating exosomes seem to be a reliable marker of PD-L1 expression in tumor tissue. The level of circulating exosomal PD-L1 increases significantly in patients with tumor progression. Ultra-trace detection of serum exosomal PD-L1 by ARTCA provides a potentially convenient way for dynamic monitoring of tumor progression for patients undergoing immunotherapy. These results demonstrate the use of CRISPR-Cas13a for protein detection, and circulating exosomal PD-L1 levels seem to be a reliable marker as well as PD-L1 expression in tumor tissue, opening up new avenues for monitoring tumor progression.","PeriodicalId":7179,"journal":{"name":"Advanced Biomedicine","volume":"222 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75798662","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, in non-small cell lung cancer (NSCLC) studies, various NLR and/or dNLR cut-oﬀs have been used, manly based on previous reports on melanoma. Methods: In this Italian multicenter retrospective study, NLR, dNLR, platelet-to-lymphocyte ratio, albumin, and lactate dehydrogenase (LDH) were longitudinally assessed in patients with stage IV non-small cell lung cancer (NSCLC) treated with ICI. The primary objective was to evaluate if baseline parameters predicted response to ICI, using Receiver Operating Characteristic (ROC) curves. Secondary endpoint was to evaluate if dynamic changing of NLR and dNLR also predicted response. Results: Data of 402 patients were collected and analyzed. Among the baseline parameters considered, NLR and dNLR were the most appropriate biomarkers according to the ROC analyses, which also identiﬁed meaningful cut-oﬀs (NLR = 2.46; dNLR = 1.61). Patients with low ratios reported a signiﬁcantly improved outcome, in terms of overall survival (p = 0.0003 for NLR; p = 0.0002 for dNLR) and progression free survival (p = 0.0004 for NLR; p = 0.005 for dNLR). The role of NLR and dNLR as independent biomarkers of response was conﬁrmed in the Cox regression model. When assessing NLR and dNLR dynamics from baseline to cycle 3, a decrease ≥1.04 for NLR and ≥0.41 for dNLR also predicted response. Conclusions in our cohort, we conﬁrmed that NLR and dNLR, easily assessable on peripheral blood, can predict response at baseline and early after ICI initiation. For both baseline and dynamic assessment, we identiﬁed clinically meaningful cut-oﬀs, using ROC curves.","PeriodicalId":7179,"journal":{"name":"Advanced Biomedicine","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86066824","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Most local CI-AKI studies in Vietnam had small sample sizes and short-term follow-up of only 24-48 hours following CA or PCI intervention, resulting in controversial conclusions. We conducted a study of the incidence of CI-AKI during a longer follow-up time period and associated risk factors among adult patients undergoing CA/ PCI at Nguyen Tri Phuong University Public Hospital and Tam Duc Private Cardiology Center in Ho Chi Minh City, Vietnam between January 2014 and March 2015. All 320 patients with CA/PCI at the two hospitals were enrolled in a retrospective cohort study. Information on demographic data, treatment, and laboratory test results was collected from the patients’ records. The total cumulative incidence of CI-AKI at 24, 48, 72 and ≥72 hours following CA/PCI was 6.7%, 12%, 14% and 16.9% respectively. Prognostic factors for CI-AKI included an increase by 1 ml/min/1,73m² in clearance creatinine before the intervention (P = 0.006, Hazard Ratio (HR) = 0.970, 95%CI 0.949 – 0.991) and an increase by 1% in ejection fraction (P = 0.023, HR = 0.984, 95%CI 0.970 – 0.998). Delayed CI-AKI was not rare after CA/PCI intervention. Therefore, it is pivotal to monitor serum creatinine in a longer time after the intervention to timely detect CI-AKI. Also, information on risk factors such as emergency interventions, chronic kidney disease, and ejection fraction < 45% could assist in predicting CI-AKI development.","PeriodicalId":7179,"journal":{"name":"Advanced Biomedicine","volume":"25 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-08-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78594640","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In general, patients with COPD exacerbation get admitted to the hospital and treated with antibiotics, glucocorticoids and inhaled bronchodilators. Oropharyngeal dysphagia is an under-recognized provoking factor for COPD exacerbation. Patients with advanced COPD often have impaired coordination of respiration and deglutition which can lead to aspiration of liquids, food particles, and saliva into the airways. Aspiration events can lead to exacerbation of symptoms and cause further decline in lung function. We described a 69-year-old male with a history of COPD who presented with progressive dyspnea, productive cough and hypoxia which required intubation and mechanical ventilation.
