Markers of renal function at admission and mortality in hip fracture patients - a single center prospective observational study.
Plasma cystatin C and shrunken pore syndrome (SPS) are associated with increased mortality in older adults. The objective was to assess the association between these markers of kidney function at admission and mortality in hip fracture patients. Hip fracture patients presenting at Lund University Hospital were eligible for inclusion. ⋯ None of the markers improved discrimination compared to the Nottingham Hip Fracture Score using ROC analysis whereas eGFRCYS and eGFRCREA improved NRI. Our conclusion is that plasma concentrations of creatinine or cystatin C, eGFRCYS or eGFRCREA or SPS at admission in hip fracture patients are associated with mortality when known risk factors are accounted for. Identification of high risk patients may be improved by eGFRCYS or eGFRCREA.

High ratio of C-reactive protein/procalcitonin predicts Mycoplasma pneumoniae infection among adults hospitalized with community acquired pneumonia.
There is limited data on serum biomarkers in distinguishing Mycoplasma pneumoniae (MP) from Streptococcus pneumoniae (SP) and viral pneumoniae (VP) etiologies of community-acquired pneumonia (CAP). A retrospective study of inpatients diagnosed with CAP at the First Affiliated Hospital of Dali University (Dali, Yunnan, China) between January 2018 and June 2020 was conducted. The demographic, clinical and laboratory data of the patients with CAP were analyzed. ⋯ CRP/PCT >350 μg/ng present better information (OR: 4.70; AUC = 0.92, p < .001, 87% sensitivity and 100% specificity). In addition, comparing MP and non-MP (SP and VP combined), CRP/PCT >350 μg/ng exhibited excellent performance (AUC = 0.90, 95%CI 0.83-0.95, p < .001, 76% sensitivity and 100% specificity). CRP/PCT ratio may be a potential index to distinguish MP-CAP from non-MP-CAP.

Utility of the neutrophil-to-lymphocyte ratio and C-reactive protein level for coronavirus disease 2019 (COVID-19).
To investigate the value of the combined detection of the neutrophil-to-lymphocyte ratio (NLR) and C-reactive protein level (CRP) in the diagnosis of COVID-19. A total of 191 patients with COVID-19 were recruited at the Third Hospital of Wuhan from 21 January 2020 to 20 February 2020. Fifty healthy volunteers were randomly selected as the control group. ⋯ Logistic regression analysis showed that the NLR, CRP, and lymphocyte percentage were independent risk factors for COVID-19. The AUC of the combined determination of NLR and CRP was 0.863, which was higher than that of NLR, CRP, WBC, and lymphocyte percentage (AUC: 0.835, 0.775, 0.416, and 0.749, respectively). Our results showed that the NLR and CRP were independent risk factors for COVID-19, and the combined detection of the NLR and CRP showed improved diagnostic performance for COVID-19.

Meta AnalysisLaboratory findings of COVID-19: a systematic review and meta-analysis.
The Coronavirus Disease (COVID-19) pandemic first broke out in December 2019 in Wuhan, China, and has now spread worldwide. Laboratory findings have been only partially described in some observational studies. To date, more comprehensive systematic reviews of laboratory findings on COVID-19 are missing. ⋯ A meta-analysis of seven studies with 1905 patients showed that increased CRP (OR 3.0, 95% CI: 2.1-4.4), lymphopenia (OR 4.5, 95% CI: 3.3-6.0), and increased LDH (OR 6.7, 95% CI: 2.4-18.9) were significantly associated with severity. These results demonstrated that more attention is warranted when interpreting laboratory findings in patients with COVID-19. Patients with elevated CRP levels, lymphopenia, or elevated LDH require proper management and, if necessary, transfer to the intensive care unit.

Differential diagnosis of tuberculous and malignant pleural effusions: comparison of the Th1/Th2 cytokine panel, tumor marker panel and chemistry panel.
The differentiation between tuberculous plural effusion (TPE) and malignant plural effusion (MPE) remains a major clinical challenge in the diagnosis and management of pleural effusions, especially in developing countries with a high incidence of tuberculosis. We aimed to evaluate the diagnostic value of cytokines, tumor markers and biochemical markers in the differentiation of TPE and MPE. Two hundred and forty-two patients were included, of whom 134 were diagnosed with MPE and 108 were diagnosed with TPE. ⋯ With a cut-off value of >2.45 pg/mL, the sensitivity and specificity of IFN-γ were 91.11 and 91.94%, respectively. TNF-α, IFN-γ, IL-6, CYFRA 21-1, CEA, ADA and Hs-CRP were useful in the differentiation between the TPE and MPE groups. IFN-γ showed a better diagnostic performance than the multitude of other markers evaluated in this study, which is satisfactory for the discrimination of TPE and MPE.
