In this task, you're given a paragraph and title from the research paper. Your task is to classify whether the given title is suitable or not for the research paper based on the given paragraph. Return "True" if title is proper according to paragraph else "False".

Q: Paragraph: Background. Recent trials suggest procalcitonin-based guidelines can reduce antibiotic use for respiratory infections. However, the accuracy of procalcitonin to discriminate between viral and bacterial pneumonia requires further dissection. Methods. We evaluated the association between serum procalcitonin concentration at hospital admission with pathogens detected in a multicenter prospective surveillance study of adults hospitalized with community-acquired pneumonia. Systematic pathogen testing included cultures, serology, urine antigen tests, and molecular detection. Accuracy of procalcitonin to discriminate between viral and bacterial pathogens was calculated. Results. Among 1735 patients, pathogens were identified in 645 (37%), including 169 (10%) with typical bacteria, 67 (4%) with atypical bacteria, and 409 (24%) with viruses only. Median procalcitonin concentration was lower with viral pathogens (0.09 ng/ mL; interquartile range [IQR], <0.05-0.54 ng/mL) than atypical bacteria (0.20 ng/mL; IQR, <0.05-0.87 ng/mL; P = .05), and typical bacteria (2.5 ng/mL; IQR, 0.29-12.2 ng/mL; P < .01). Procalcitonin discriminated bacterial pathogens, including typical and atypical bacteria, from viral pathogens with an area under the receiver operating characteristic (ROC) curve of 0.73 (95% confidence interval [CI], .69-.77). A procalcitonin threshold of 0.1 ng/mL resulted in 80.9% (95% CI, 75.3%-85.7%) sensitivity and 51.6% (95% CI, 46.6%-56.5%) specificity for identification of any bacterial pathogen. Procalcitonin discriminated between typical bacteria and the combined group of viruses and atypical bacteria with an area under the ROC curve of 0.79 (95% CI, .75-.82). Conclusions. No procalcitonin threshold perfectly discriminated between viral and bacterial pathogens, but higher procalcitonin strongly correlated with increased probability of bacterial pathogens, particularly typical bacteria.

Q: Paragraph: microRNAs (miRNAs) represent a newly identified class of nonprotein-coding *22 nt small RNA that plays important roles in multiple biological processes by degrading targeted mRNA or repressing mRNA translation. This study observed the morphology of swine testicular tissue at different developmental stages (including 1-day old, 1-7 month old) by Hematoxylin-eosin staining. We also examined the expression of miR-499 and its target genes (CYLC1, DMRT1, QKI, XRN2, ZNF313) in samples of tissue slices using quantitative reversetranscription polymerase chain reaction, which showed that miR-499 had a significant negative correlation with QKI gene. Then, the proteins of QKI gene expression were determined by western blot, which were consistent with results of quantitative polymerase chain reaction (qPCR) detection. Therefore, the luciferase reporter gene system was used to verify correlation between miR-499 and QKI gene. Activity of luciferase was significantly lower in miR-499 co-transfected with pmiR-RB-REPORT-QKI-WT group than the miR-499 co-transfected with pmiR-RB-REPORT-QKI-mut/si groups, indicating that target sequence of miR-499 existed in 3¢UTR of QKI gene. Furthermore, the expressions of miR-499 and QKI were detected in testicular cells that were transfected with miR-499, miR-499 negative control and untreated. The results showed that the diameter of convoluted seminiferous tubule growth increased with age. Significantly different expressions of miR-499 and its target genes were found in swine testicular tissue at different developmental stages ( p < 0.05), overexpressing miR-499 analysis, suggesting that miR-499 was negatively correlated to the expression of QKI ( p < 0.05). In conclusion, QKI is a target gene of miR-499.

Q: Paragraph: The worldwide impact of COVID 19 continues to be felt as hospitals in all countries reduce elective and nonurgent cases to allow staffing and resources to be deployed elsewhere. Urgent gynaecological and cancer procedures are continuing, and it is imperative all theatre staff are protected and risks of SARS-CoV-2 viral transmission reduced when operating on asymptomatic, suspected or confirmed COVID 19 patients. In particular, there are concerns relating to the transmission of COVID 19 during gynaecological laparoscopic surgery, arising from the potential generation of SARS-CoV-2 contaminated aerosols from CO2 leakage and the creation of smoke from the use of energy devices. The aim of this paper is to review all the up to date evidence, including experiences from China and Italy, to guide the safe management of such patients when undergoing gynaecological procedures.
