    新型冠状病毒属于SARS和MERS-CoV家族,较早的影响更为可怕,病态病例的稳步增加证明了这一点。COVID-19的平均潜伏期为1-14天,平均为6天。目的-评估COVID-19患者死亡率的预测因素。目标-1.评估与COVID-19患者死亡率相关的风险预测因子2。提出了预防未来疫情死亡的预测模型。
    研究设计-病例对照研究。研究地点-三级护理中心,Nanded,马哈拉施特拉邦.本研究包括400例因新冠肺炎死亡的病例和400例对照以1:1的比例在新冠肺炎疾病中存活。
    入学时,在SpO2百分比方面,病例和对照组之间观察到显着差异(p<0.05)。病例中相关合并症的比例非常高,即与具有29.25%合并症的比例的对照相比,75.75%。与对照组相比,病例的中位住院天数显着降低(3天vs12天,P<0.001)。
    住院时间(以天为单位)在病例和对照组之间存在显着差异(3天比12天);病例的住院时间较少(中位数为3天),因为他们报告较晚,因此死亡较早;因此得出结论,提前入院将减少因COVID-19死亡的机会。
    UNASSIGNED: The novel Coronavirus is belonging to the family of SARS & MERS-CoV, the impact of the earlier is more dreadful as demonstrated by the steady increase in morbid cases. The average incubation period of COVID-19 is 1-14 days with a mean of 6 days. Aim - To evaluate predictors of mortality among COVID-19 patients. Objectives - 1. To assess risk predictors associated with mortality among COVID-19 patients 2. To a suggest prediction model for preventing mortality in future outbreaks.
    UNASSIGNED: Study design - A case-control study. Study place -Tertiary care center, Nanded, Maharashtra. The present study included 400 cases that died off due to Covid-19 and 400 controls survived COVID-19 disease in a 1:1 proportion.
    UNASSIGNED: On admission, a significant difference was observed among cases and controls with reference to the percentage of SpO2 (p < 0.05). The proportion of associated co-morbidities among cases was very high i.e., 75.75% as compared to controls with a proportion of 29.25% co-morbidities. The median days of hospital stay were significantly lower in cases compared to controls (3 days vs 12 days, P < 0.001).
    UNASSIGNED: Length of hospital stay (in days) was showing a significant difference among cases and control (3 days Vs 12 days); hospital stay was less (median 3 days) for cases, as they reported late and thus died earlier; hence concluded that early hospital admission will decrease chances of death due to COVID-19.

    未经证实:多囊卵巢综合征(PCOS)始于青春期,并在以后几年有心血管和代谢成分。胱抑素C和高敏C反应蛋白(hs-CRP)水平以及中性粒细胞-淋巴细胞和血小板-淋巴细胞比率与代谢和炎症事件相关。这里,我们评估了正常和超重PCOS青少年的炎症和代谢参数.
    UNASSIGNED:这项前瞻性病例对照研究纳入了90名PCOS青少年和100名年龄和BMI健康青少年,分为正常体重(NW)和超重(OW)。根据炎症和代谢参数(血清胱抑素C,hs-CRP,中性粒细胞-淋巴细胞比率(NLR),血小板-淋巴细胞比率(PLR),脂质,空腹血糖-胰岛素(FBG-FI),HOMA-IR水平,腰围[WC],和腰臀比[WHR])。比较参数之间的关系并评估预测能力。
    未经批准:胱抑素C,hs-CRP,NLR,甘油三酯(TG),FBG-FI,HOMA-IR,WC,PCOS患者的WHR明显更高。NWPCOS组TG明显增高,胱抑素C,hs-CRP,以及NLR与OW控件。在OWPCOS中观察到最高的HOMA-IR值(p<0.05)。胱抑素C和hs-CRP敏感性和特异性差异有统计学意义(p<0.05)。胱抑素C和hs-CRP与其他代谢指标呈正相关。
    未经批准:与BMI无关,与对照组相比,PCOS青少年的炎症和代谢参数明显更高,而OW青少年的炎症和代谢参数甚至更差。因此,应鼓励PCOS青少年保持健康的生活方式和体重,以避免代谢风险.Hs-CRP和胱抑素C可能是预测未来代谢风险的有希望的标志物。
    UNASSIGNED: Polycystic ovary syndrome (PCOS) begins in adolescence and has cardiovascular and metabolic components in later years. Cystatin C and high-sensitivity C-reactive protein (hs-CRP) levels and neutrophil-lymphocyte and platelet-lymphocyte ratios are associated with metabolic and inflammatory events. Here, we evaluated inflammatory and metabolic parameters in normal and overweight adolescents with PCOS.
    UNASSIGNED: This prospective case-control study enrolled 90 adolescents with PCOS and 100 matched by age and BMI healthy adolescents classified as either normal weight (NW) and overweight (OW). Groups were compared based on inflammatory and metabolic parameters (serum cystatin C, hs-CRP, neutrophil-lymphocyte ratio (NLR), platelet-lymphocyte ratio (PLR), lipids, fasting blood glucose-insulin (FBG-FI), HOMA-IR levels, waist circumference [WC], and waist-hip ratio [WHR]). The relationship between the parameters were compared and predictive abilities were evaluated.
    UNASSIGNED: Cystatin C, hs-CRP, NLR, triglyceride (TG), FBG-FI, HOMA-IR, WC, and WHR were significantly higher in those with PCOS. The NW PCOS group had significantly higher TG, cystatin C, hs-CRP, and NLR versus OW controls. The highest HOMA-IR values were observed in OW PCOS (p < .05). Cystatin C and hs-CRP sensitivity and specificity were significant (p < 0.05). Cystatin C and hs-CRP were positively correlated with other metabolic parameters.
    UNASSIGNED: Independent of BMI, inflammatory and metabolic parameters are significantly higher in adolescents with PCOS compared to controls and even worse in those who are also OW. Therefore, adolescents with PCOS should be encouraged to maintain healthy lifestyles and weights to avoid metabolic risks. Hs-CRP and cystatin C could be promising markers to predictive of future metabolic risks.

    引言由于其与妊娠生理学的相似性,很难诊断孕妇急性阑尾炎的症状。在这项研究中,我们研究了实验室参数在孕妇急性阑尾炎诊断中的诊断价值.材料和方法对42例妊娠期行阑尾切除术的患者进行评估。人口特征,检查了患者的实验室参数和影像学方法。根据病理结果,将两组患者分别评估为正常阑尾和急性阑尾炎。此外,形成非妊娠对照组,比较妊娠组和对照组的结果.结果42例患者平均年龄30±6岁,16例(38.1%)患者病理结果为正常。作为成像方法,对所有患者进行了超声检查,对两名患者进行了MRI检查。当比较正常阑尾组和急性阑尾炎组时,在实验室参数方面没有观察到显著差异(中性粒细胞,淋巴细胞,白细胞和血小板计数,中性粒细胞-淋巴细胞比率,血小板-淋巴细胞比率,平均血小板体积,红细胞分布宽度,和妊娠三个月(P>0.05)。与对照组相比,接受阑尾切除术的组的阑尾切除术阴性率明显更高(P=0.001)。结论单纯的实验室指标不足以诊断妊娠合并急性阑尾炎。如果临床检查,实验室参数和USG不足以诊断,MRI是应考虑降低阴性阑尾切除术率的成像方法。
    Introduction It is difficult to diagnose the symptoms of acute appendicitis in pregnant women due to its similarities with pregnancy physiology. In this study, we examined the diagnostic value of laboratory parameters in the diagnosis of acute appendicitis in pregnant women. Material and methods Forty-two patients who underwent appendectomy during pregnancy were evaluated. The demographic characteristics, laboratory parameters and imaging methods of the patients were examined. According to the pathology results, the patients were evaluated in two groups as normal appendix and acute appendicitis. In addition, a non-pregnant control group was formed to compare the results between the pregnant and control groups. Results The mean age of the 42 patients was 30±6 years, and the pathology results were evaluated as normal in 16 (38.1%) of the patients. As imaging methods, ultrasonography was undertaken in all patients, with MRI being additionally performed in two patients. When the normal appendix and acute appendicitis groups were compared, no significant difference was observed in terms of laboratory parameters (neutrophil, lymphocyte, white blood cell and platelet counts, neutrophil-lymphocyte ratio, platelet-lymphocyte ratio, mean thrombocyte volume, red cell distribution width, and pregnancy trimesters (P>0.05). The group that had undergone appendectomy had a significantly higher rate of negative appendectomy compared to the control group (P=0.001). Conclusion Laboratory parameters alone cannot be sufficient for the diagnosis of acute appendicitis in pregnant patients. If clinical examination, laboratory parameters and USG are not sufficient for diagnosis, MRI is the imaging method that should be considered to reduce negative appendectomy rate.

    背景:中性粒细胞-淋巴细胞比率(NLR)是易于计算的血液测试参数,可以作为预测许多炎症性疾病的标志物。这项研究的目的是评估和比较母体血液中的NLR与白细胞(WBC)计数和C反应蛋白(CRP)浓度,以预测组织学绒毛膜羊膜炎。
    方法:这是一项病例对照研究,研究对象为137名胎龄在22+0~34+6周的早产胎膜早破(PPROM)妇女。血样,在分娩前48小时内和皮质类固醇给药后至少48小时收集,被选中进行分析。通过将嗜中性粒细胞的数量除以淋巴细胞的数量来计算NLR。通过胎盘膜和绒毛膜板的组织病理学评估来诊断绒毛膜羊膜炎。
    结果:诊断为组织学绒毛膜羊膜炎(HCA)的患者的白细胞水平明显升高,CRP和NLR(p值<0.001)。WBC的水平,CRP和NLR预测HCA的曲线下面积(AUC)分别为0.81、0.81和0.89。NLR的AUC明显高于WBC,但NLR和CRP的AUC无显著差异。发现NLR的截止水平为5,97,其具有77%的灵敏度和95%的特异性。
    结论:NLR对HCA具有良好的预测价值,可作为预测34周孕前未足月胎膜早破患者绒毛膜羊膜炎的额外诊断指标。
    BACKGROUND: The neutrophil-lymphocyte ratio (NLR) is easily calculated blood test parameter, which can be used as marker to predict many inflammatory disorders. The aim of this study was to assess and compare the NLR in maternal blood with the white blood cell (WBC) count and C-reactive protein (CRP) concentration for the prediction of histological chorioamnionitis.
    METHODS: This was a case-control study of 137 woman with preterm premature rupture of membranes (PPROM) at a gestational age between 22+ 0 and 34+ 6 weeks. Blood samples, collected less than 48 h before delivery and at least 48 h after the administration of corticosteroids, were selected for the analysis. The NLR was calculated by dividing the number of neutrophils by the number of lymphocytes. Chorioamnionitis was diagnosed by the histopathological evaluation of placental membranes and chorionic plate.
    RESULTS: Patients with diagnosed histological chorioamnionitis (HCA) had significantly higher levels of WBC, CRP and NLR (p-value < 0.001). Levels of WBC, CRP and NLR predicted HCA with an area under the curve (AUC) of 0.81, 0.81 and 0.89, respectively. NLR had statistically significantly higher AUC than WBC, but no significant difference was found between AUCs of NLR and CRP. The cut-off level of NLR was found to be 5,97, which had a sensitivity of 77 % and a specificity of 95 %.
    CONCLUSIONS: NLR has a good predictive value for HCA and could be used as an additional diagnostic marker for predicting histological chorioamnionitis in cases with preterm premature rupture of membranes before 34 weeks of gestation.

    在先前的研究中,炎症在认知障碍的病理生理学中起着重要作用。中性粒细胞-淋巴细胞比率(NLR)是全身性炎症的可靠指标。
    这项研究的目的是调查NLR与轻度认知障碍(MCI)之间的关系。并进一步探讨炎症标志物NLR在中国老年人MCI中的诊断潜力。
    本研究连续评估了186名MCI受试者和153名认知功能正常的受试者。在空腹血液样品中测量中性粒细胞(NEUT)计数和淋巴细胞(LYM)计数。通过将绝对NEUT计数除以绝对LYM计数来计算NLR。多变量logistic回归用于评估NLR和MCI之间的潜在关联。使用接收器工作特征(ROC)曲线分析来分析用于预测MCI的NLR。
    MCI组NLR显著高于认知功能正常组(2.39±0.55vs.1.94±0.51,P<0.001)。Logistic回归分析显示,NLR升高是MCI的独立危险因素(OR:4.549,95%CI:2.623~7.889,P<0.001)。ROC分析表明,MCI的最佳NLR截止点为2.07,灵敏度为73.66%,69.28%的特异性,74.48%的阳性预测值(PPV)和68.36%的阴性预测值(NPV)。相对于NLR<2.07,NLR≥2.07的受试者显示出更高的风险(OR:5.933,95%CI:3.467-10.155,P<0.001)。
    NLR升高与MCI风险增加显著相关。特别是,NLR水平高于阈值2.07与MCI的概率显著相关。
    Inflammation plays a significant role in the pathophysiology of cognitive impairment in previous studies. Neutrophil-lymphocyte ratio (NLR) is a reliable measure of systemic inflammation.
    The aim of this study was to investigate the association between NLR and mild cognitive impairment (MCI), and further to explore the diagnostic potential of the inflammatory markers NLR for the diagnosis of MCI in elderly Chinese individuals.
    186 MCI subjects and 153 subjects with normal cognitive function were evaluated consecutively in this study. Neutrophil (NEUT) count and Lymphocyte (LYM) count were measured in fasting blood samples. The NLR was calculated by dividing the absolute NEUT count by the absolute LYM count. Multivariable logistic regression was used to evaluate the potential association between NLR and MCI. NLR for predicting MCI was analyzed using Receiver Operating Characteristic (ROC) curve analysis.
    The NLR of MCI group was significantly higher than that of subjects with normal cognitive function (2.39 ± 0.55 vs. 1.94 ± 0.51, P < 0.001). Logistic regression analysis showed that higher NLR was an independent risk factor for MCI (OR: 4.549, 95% CI: 2.623-7.889, P < 0.001). ROC analysis suggested that the optimum NLR cut-off point for MCI was 2.07 with 73.66% sensitivity, 69.28% specificity, 74.48% Positive Predictive Values (PPV) and 68.36% negative predictive values (NPV). Subjects with NLR ≥ 2.07 showed higher risk relative to NLR < 2.07 (OR: 5.933, 95% CI: 3.467-10.155, P < 0.001).
    The elevated NLR is significantly associated with increased risk of MCI. In particular, NLR level higher than the threshold of 2.07 was significantly associated with the probability of MCI.

    Aim: The present study aims to determine whether various hematological parameters and ratios of patients could be used to diagnose AMI. Materials and Methods: The subjects of the study are the patients who were hospitalized with an acute mesenteric ischemia (AMI) pre-diagnosis and underwent surgery as a consequence. The patients who were determined to have the diagnosis of AMI intraoperatively are categorized in the AMI Group. The patients whose operations do not reveal AMI (negative exploration) are categorized in the Control Group. These two groups are compared in terms of hematological parameters and rates. Results: In the study, the PLR (p = 0.017), NLR (p = 0.33), PDW (0.023), RDW (p = 0.025) values are significantly higher in the AMI group compared to the control group while the LYMP (p = 0.023) count is significantly lower. Conclusions: For the patients admitted to the emergency clinics with suspected AMI, the increased PLR, NLR, PDW, and RDW values together with the reduced lymphocyte count can be used to support the diagnosis.

    OBJECTIVE: Endodontic originated chronic apical periodontitis (AP) is an inflammatory disease of periapical tissue. High-sensitivity C-reactive protein (hsCRP) as an inflammatory marker and hemogram indexes provide valuable information to clinicians for diagnosis, screening and follow-up of various diseases. The aim of this study was to investigate AP in terms of its association with hemogram indices and hsCRP levels.
    METHODS: Study includes 104 patients with AP and 40 participants as the control group. 160 teeth were diagnosed as AP through digital radiographic images and scored with respect to Periapical Index (PAI) scoring. Afterwards, patients were categorized into 3 grades in accordance with both the number and the severity of AP. AP grade 0 was considered for the control group with regard to a new scoring system. Patients with only one tooth involved with AP with a PAI score of 3 or 4 were categorized as an AP Grade 1, when a patient had more than one tooth with a PAI score of 3 or 4 he was classified as an AP Grade 2 and a patient with at least one tooth scored as a PAI 5 was rated as an AP Grade 3. Hemograms and hsCRP levels were measured for each individual to establish a correlation with inflammatory markers.
    RESULTS: The neutrophil/lymphocyte ratio (NLR) levels of patients with AP Grade 3 were significantly higher than all other AP grades (p < .05). hsCRP levels in patients with an AP Grade 2 and 3 were higher than both AP Grade 0 and 1 (p < .05).
    CONCLUSIONS: hsCRP levels of patients were reliable predictive indicators for AP severity in correlation with the new proposed scoring system for AP.

    Neutrophil-lymphocyte ratio(NLR) is a novel marker for the evaluation of inflammation and has not been evaluated previously in patients with AD.
    To investigate the relationship between NLR and the clinical findings of AD.
    Sixty-six children with AD were included in the study.The control group was included 66 children who have no allergic and chronic diseases.The immunoglobulin(Ig)E levels and complete blood count were measured. Skin prick tests were performed using the same antigens for all patients.
    NLR was not significant between the patient and control groups (p>0.05).The patients with AD were divided into 3 groups according to their SCORAD score as mild, moderate and severe AD.No statistically significant difference was present between groups in terms of demographic and clinical characteristics,eosinohil-lymphocyte ratio,eosinophil-neutrophil ratio,the percentage of eosinophil, IgE,the sensitivity of skin tests(p>0.05). However,NLR and sensitivity to house dust mite were significantly different among groups(respectively,p=0.037,p:0.043).SCORAD scores were weak positively correlated with NLR levels,eosinophil-lymphocyte ratio and the sensitivity of house dust mite (respectively,r:0.329;p:0.007,r:0.264;p:00035,r:0.325;p:0.008).
    We didn\'t found significant difference in term of mean NLR betweeen patients with AD and control group. NLR was found significantly higher in severe AD patients than mild AD patients.The house dust mite sensitivity, eosinohil-lymphocyte ratio and NLR were correlated with AD severity.
