Abstract
Human cutaneous melanoma (CM) is a highly invasive malignancy arising from melanocytes, and accompanied by ever-increasing incidence and mortality rates worldwide. Interestingly, microRNAs (miRNAs) possess the ability to regulate CM cell biological functions, resulting in the aggressive progression of CM. Nevertheless, a comprehensive understanding of the underlying mechanism remains elusive. Accordingly, the current study sought to elicit the functional role of miR-141-3p in human CM cells in association with fibroblast growth factor 13 (FGF13) and the MAPK pathway. First, miR-141-3p expression patterns were detected in human CM tissues and cell lines, in addition to the validation of the targeting relationship between miR-141-3p and FGF13. Subsequently, loss- and gain-of-function studies of miR-141-3p were performed to elucidate the functional role of miR-141-3p in the malignant features of CM cells. Intriguingly, our findings revealed that FGF13 was highly expressed, whereas miR-141-3p was poorly expressed in the CM tissues and cells. Further analysis highlighted FGF13 as a target gene of miR-141-3p. Meanwhile, overexpression of miR-141-3p inhibited the proliferative, invasive, and migratory abilities of CM cells, while enhancing their apoptosis accompanied by downregulation of FGF13 and the MAPK pathway-related genes. Collectively, our findings highlighted the inhibitory effects of miR-141-3p on CM cell malignant properties via disruption of the FGF13-dependent MAPK pathway, suggesting a potential target for treating human CM.

Abstract
OBJECTIVE Epidemiological information is essential in providing appropriate empiric antimicrobial therapy for pneumonia. This study aimed to clarify the epidemiology of community-acquired pneumonia (CAP) by conducting a systematic review of published studies in Japan. DESIGN Systematic review. DATA SOURCE PubMed and Ichushi web database (January 1970 to October 2022). ELIGIBILITY CRITERIA Clinical studies describing pathogenic micro-organisms in CAP written in English or Japanese, excluding studies on pneumonia other than adult CAP, investigations limited to specific pathogens and case reports. DATA EXTRACTION AND SYNTHESIS Patient setting (inpatient vs outpatient), number of patients, concordance with the CAP guidelines, diagnostic criteria and methods for diagnosing pneumonia pathogens as well as the numbers of each isolate. A meta-analysis of various situations was performed to measure the frequency of each aetiological agent. RESULTS Fifty-six studies were included and 17 095 cases of CAP were identified. Pathogens were undetectable in 44.1% (95% CI 39.7% to 48.5%). Streptococcus pneumoniae was the most common cause of CAP requiring hospitalisation or outpatient care (20.0% (95% CI 17.2% to 22.8%)), followed by Haemophilus influenzae (10.8% (95% CI 7.3% to 14.3%)) and Mycoplasma pneumoniae (7.5% (95% CI 4.6% to 10.4%)). However, when limited to CAP requiring hospitalisation, Staphylococcus aureus was the third most common at 4.9% (95% CI 3.9% to 5.8%). Pseudomonas aeruginosa was more frequent in hospitalised cases, while atypical pathogens were less common. Methicillin-resistant S. aureus accounted for 40.7% (95% CI 29.0% to 52.4%) of S. aureus cases. In studies that used PCR testing for pan-respiratory viral pathogens, human enterovirus/human rhinovirus (9.4% (95% CI 0% to 20.5%)) and several other respiratory pathogenic viruses were detected. The epidemiology varied depending on the methodology and situation. CONCLUSION The epidemiology of CAP varies depending on the situation, such as in the hospital versus outpatient setting. Viruses are more frequently detected by exhaustive genetic searches, resulting in a significant variation in epidemiology.

Abstract
Introduction Several serum inflammatory markers are associated with poor clinical outcomes in community-acquired pneumonia (CAP). However, the prognosis and early treatment response in hospitalized CAP patients based on serial neutrophil-to-lymphocyte ratio (NLR) measurement has never been investigated. Methods We performed a retrospective observational study for 175 consecutive patients hospitalized with CAP between February 2016 and February 2018. NLR, C-reactive protein (CRP) and procalcitonin levels were measured on admission day (D1) and on hospital day 4 (D4). The Pneumonia Severity Index (PSI) was also assessed on admission. The primary endpoint was all-cause death within 30 days after admission. The secondary endpoint was early treatment response such as intensive care unit (ICU) admission during hospitalization and clinical unstability on day 4. Results The 30-day mortality rate was 9.7%. In multivariate analysis, NLR D4 (OR: 1.11; 95% CI: 1.04–1.18; P = 0.003) and its incremental change (NLR D4/D1 >1) (OR: 7.10; 95% CI: 2.19–23.06; P = 0.001) were significant predictors of 30-day mortality. NLR D4 and its incremental change were significant predictors of ICU admission and clinical unstability on day 4 in multivariate analyses. Adding of incremental NLR change significantly improved the prognostic ability of the PSI. The additive value of incremental NLR change for the prognostic ability of the PSI was larger than that of incremental CRP change. Conclusion Serial NLR measurement represents useful laboratory tool to predict the prognosis and early treatment response of hospitalized CAP patients.

Abstract
Globally, tuberculosis is the leading infectious cause of death; discovering biomarkers that predict a high mortality risk may improve treatment outcomes. We prospectively enrolled 252 pulmonary tuberculosis patients who were not coinfected with human immunodeficiency virus and initiated antituberculosis treatment, measured serum procalcitonin levels (PCT), and assessed mortality risk. PCT serum levels higher than 0.13 (day 0), 0.05 (day 7), 0.12 (day 14), or 0.06 (day 28) ng/mL predicted nonsurvivors with odds ratios of 7.9, 14.3, 20.0, and 7.3, respectively (P ≤ .005 for all), respectively. Therefore, serum PCT levels are a promising mortality risk indicator for patients with pulmonary tuberculosis. Main Point. For patients with pulmonary tuberculosis, a promising mortality risk indicator is the level of serum procalcitonin, which is weakly associated with sputum bacterial load and independent of radiographic findings.

Abstract
INTRODUCTION Procalcitonin expression is thought to be stimulated by bacteria and suppressed by viruses via interferon signalling. Consequently, during respiratory viral illness, clinicians often interpret elevated procalcitonin as evidence of bacterial coinfection, prompting antibiotic administration. We sought to evaluate the validity of this practice and the underlying assumption that viral infection inhibits procalcitonin synthesis. METHODS We conducted a retrospective cohort study of patients hospitalised with pure viral infection (n=2075) versus bacterial coinfection (n=179). The ability of procalcitonin to distinguish these groups was assessed. In addition, procalcitonin and interferon gene expression were evaluated in murine and cellular models of influenza infection. RESULTS Patients with bacterial coinfection had higher procalcitonin than those with pure viral infection, but also more severe disease and higher mortality (p<0.001). After matching for severity, the specificity of procalcitonin for bacterial coinfection dropped substantially, from 72% to 61%. In fact, receiver operating characteristic curve analysis showed that procalcitonin was a better indicator of multiple indices of severity (eg, organ failures and mortality) than of coinfection. Accordingly, patients with severe viral infection had elevated procalcitonin. In murine and cellular models of influenza infection, procalcitonin was also elevated despite bacteriologic sterility and correlated with markers of severity. Interferon signalling did not abrogate procalcitonin synthesis. DISCUSSION These studies reveal that procalcitonin rises during pure viral infection in proportion to disease severity and is not suppressed by interferon signalling, in contrast to prior models of procalcitonin regulation. Applied clinically, our data suggest that procalcitonin represents a better indicator of disease severity than bacterial coinfection during viral respiratory infection.

Abstract
Historically, elevations in procalcitonin (PCT) have been implicated in medullary thyroid cancer and neuroendocrine tumors. More recently, the trending of PCT has been suggested as a monitor of infection to assess the presence, clearance and eradication of infection, especially in cancer patients. Its increase serves as a marker of bacterial infections. During homeostasis it is produced by most tissues in the body at an extremely low level (<.01 ng/mL) and is often induced by bacterial endotoxins. In cancer patients additional factors influence these levels. Metastasis in particular is linked with relatively higher PCT levels. We present a case of an afebrile patient with undifferentiated pleomorphic sarcoma who underwent 25 cycles of radiation therapy and presented one month later with elevated procalcitonin, lactic acid, and leukocytosis. All infectious work up was negative. Findings were incidental after a hospital visit for dehydration. Leukocytosis and lactic acidosis resolved after four days into the hospitalization. Procalcitonin, however, remained elevated over four months in the range of 2-5 ng/mL. The patient has no findings of metastatic disease. To our knowledge, there has never been a report in the literature describing a prolonged elevation of procalcitonin in a patient with a non-metastatic sarcoma without any signs of infection or any other underlying cause. The elevation of PCT has been noted in patients who suffered burns, trauma, minor and major surgery, and cardiogenic shock in addition to infection. Increases have served as signs of worsening patient outcomes and elevated rate of complications. Trending PCT can help in appropriated antibiotic use as it has been shown to decrease antibiotic use by 2.4 days. PCT trends have been increasing in value making idiopathic elevations found in combination undifferentiated pleomorphic sarcoma an important addition to the literature.

Abstract
Pneumonia is a type of acute lower respiratory infection that is common and severe. The outcome of lower respiratory infection is determined by the degrees to which immunity is protective and inflammation is damaging. Intercellular and interorgan signaling networks coordinate these actions to fight infection and protect the tissue. Cells residing in the lung initiate and steer these responses, with additional immunity effectors recruited from the bloodstream. Responses of extrapulmonary tissues, including the liver, bone marrow, and others, are essential to resistance and resilience. Responses in the lung and extrapulmonary organs can also be counterproductive and drive acute and chronic comorbidities after respiratory infection. This review discusses cell-specific and organ-specific roles in the integrated physiological response to acute lung infection, and the mechanisms by which intercellular and interorgan signaling contribute to host defense and healthy respiratory physiology or to acute lung injury, chronic pulmonary disease, and adverse extrapulmonary sequelae. Pneumonia should no longer be perceived as simply an acute infection of the lung. Pneumonia susceptibility reflects ongoing and poorly understood chronic conditions, and pneumonia results in diverse and often persistent deleterious consequences for multiple physiological systems.

Abstract
The effects of microRNA-141 (miR-141) on epithelial-mesenchymal transition (EMT), and ovarian cancer cell migration and invasion were investigated. SKOV3 cells were transfected with the miR-141 mimic (mimic group), inhibitor (inhibitor group) and nonspecific sequences (NC group), and left untransfected group (blank group). The reverse transcription-quantitative polymerase chain reaction (RT-qPCR) was used to detect the expression of miR-141 in SKOV3 cell lines. Then, mRNA levels and protein expression of EMT markers were determined by RT-qPCR and western blotting, respectively. Cell proliferation was assessed using an MTT assay, followed by analysis of cell invasion and migration. SPSS software was used for statistical analysis. The results demonstrated that miR-141 expression in the mimic group was increased compared with the NC or blank group. Compared with the NC or blank group, upregulation of epithelial-cadherin (E-cadherin) and integrin-β, and downregulation of zinc finger E-box-binding homeobox (ZEB) was observed in the mimic group. The rate of cell proliferation decreased in the mimic group and increased in the inhibitor group when compared with the NC group (P<0.05). The number of invasive cells significantly increased in the inhibitor group and decreased in the mimic group when compared with the NC group (P<0.01). Compared with the NC group, the migratory rate was decreased in the mimic group, and increased in the inhibitor group at 24 and 48 h (all P<0.01). In conclusion, overexpression of miR-141 caused upregulation of E-cadherin, inhibited cell proliferation and EMT, and decreased cell invasion and migration in the SKOV3 cell line.

Abstract
Background The objective of this study was to explore the diagnostic and prognostic value of soluble triggering receptor expressed on myeloid cell 1 (sTREM-1), soluble cluster of differentiation 14 (sCD14), soluble cluster of differentiation 163 (sCD163), interleukin-6 (IL-6), procalcitonin (PCT), and C-reactive protein (CRP) serum levels for patients with severe sepsis and septic shock in an intensive care unit (ICU). Methods Fifty patients admitted at the ICU with the diagnosis of severe sepsis or septic shock were studied. SOFA and APACHE II scores as well as serum biomarkers were measured at days 0, 2 and 5. The influence of these variables on 28-day mortality was analyzed. Twenty healthy individuals served as controls. Results Baseline serum concentrations of sTREM-1, sCD163, IL-6 and PCT correlated with SOFA score. Only sTREM-1 levels correlated with APACHE II score. The 28-day mortality rate for all patients was 42%. The absence of risk factors for infection, presence of septic shock, baseline values of sCD14 and decrease of PCT and IL-6 from baseline to day 5 were variables associated to mortality in the univariate analysis. The unique independent factor associated to mortality in the multivariate analysis was a decrease of PCT higher than 50% from days 0 to 5. Conclusions Serum levels of sTREM-1 are correlated with the severity of sepsis. A 50% decrease of PCT was the unique variable associated with survival in the multivariate analysis.

METHODS 352 hospitalized community-acquired pneumonia patients in an observational cohort study in which procalcitonin was measured three times serially, on admission (Day 1) and 2-3 days (Day 3) and 6-8 days (Day 7) after admission, between October 2010 and February 2016 were reviewed retrospectively. Antibiotics could be stopped if Day 7 procalcitonin was <0.25 ng mL-1 or ≤10% of the higher value of procalcitonin on Day 1 or 3. Antibiotic duration and costs and recurrence and mortality rates were evaluated in mild to moderate or severe pneumonia by theoretical procalcitonin guidance for community-acquired pneumonia treatment. RESULTS Using theoretical procalcitonin guidance, antibiotic duration could be reduced from 12.6 to 8.6 days (P < 0.001), while costs could be reduced from 45,833 to 38,952 yen (P = 0.005). Among the patients in whom theoretical procalcitonin guidance could be adopted, recurrence rates (5.6% vs. 8.1%, P = 0.15) and mortality rates (0% vs. 5.1%, P = 0.07) did not worsen between the group having the same antibiotic durations as with theoretical procalcitonin guidance in actual practice (N = 71) and the group having durations more than 2 days longer in actual practice than in theoretical procalcitonin guidance (N = 198). There was no significant difference in pneumonia severity using A-DROP, CURB-65, and PSI between two groups. CONCLUSIONS Procalcitonin-guided therapy may be useful in hospitalized community-acquired pneumonia patients to reduce antibiotic duration and costs without worsening the prognosis.

Diagnostic and prognostic value of soluble CD14 subtype (Presepsin) for sepsis and community-acquired pneumonia in ICU patients. Ann Intensive Care 2016; 6:59. [PMID: 27389015 PMCID: PMC4936977 DOI: 10.1186/s13613-016-0160-6] [Citation(s) in RCA: 74] [Impact Index Per Article: 9.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/20/2016] [Accepted: 06/20/2016] [Indexed: 12/21/2022] Open
Abstract
Background The soluble CD14 subtype, Presepsin, appears to be an accurate sepsis diagnostic marker, but data from intensive care units (ICUs) are scarce. This study was conducted to evaluate the diagnostic and prognostic value of Presepsin in ICU patients with severe sepsis (SS), septic shock (SSh) and severe community-acquired pneumonia (sCAP). Methods Presepsin and procalcitonin (PCT) levels were determined for patients at admission to ICU. Four groups have been differentiated: (1) absence or (2) presence of systemic inflammatory response syndrome, (3) SS or (4) SSh; and 2 groups, among the patients admitted for acute respiratory failure: absence or presence of sCAP. Biomarkers were tested for diagnosis of SS, SSh and sCAP and for prediction of ICU mortality. Results One hundred and forty-four patients were included: 44 SS and 56 SSh. Plasma levels of Presepsin and PCT were significantly higher in septic than in non-septic patients and in SSh as compared to others. The sepsis diagnostic accuracy of Presepsin was not superior to that of PCT (AUC: 0.75 vs 0.80). In the 72/144 patients admitted for acute respiratory failure, the capability of Presepsin to diagnose sCAP was significantly better than PCT. Presepsin levels were also predictive of ICU mortality in sepsis and in sCAP patients. Conclusion Plasma levels of Presepsin were useful for the diagnosis of SS, SSh and sCAP and may predict ICU mortality in these patients.

Abstract
OBJECTIVES The pneumonia severity index and CURB-65 are risk assessment tools widely used in community-acquired pneumonia (CAP). However, limitations in these prognostic scores have led to increasing interest in finding biomarkers that might provide additional information. To date, the role of these biomarkers has not been fully elucidated. METHODS We systematically searched the Medline, Web of Knowledge, Science Direct, and LILACS databases. We included studies that assessed the accuracy of biomarkers for the prediction of in-hospital or ≤30-day mortality, in hospitalized adults with CAP. Two independent investigators extracted patient and study characteristics, which were thereafter pooled using a random effects model. Relationships between sensitivity and specificity of biomarkers and prognostic scores were plotter using the area under the receiver operator characteristic curve (AUC). RESULTS We included 24 articles and 2 databases from 1069 reviewed abstracts, which provided 10,319 patients for analysis. Reported mortality rates varied from 2.4% to 34.6%. The highest AUC values for predicting mortality were associated with pro-adrenomedullin (0.80) and prohormone forms of atrial natriuretic peptide (0.79), followed by cortisol (0.78), procalcitonin (0.75), copeptin (0.71), and C-reactive protein (0.62). There were no statistically significant differences between the AUCs of the studied biomarkers, other than for copeptin and C-reactive protein, which performed comparatively poorly. When compared with the CAP-specific scores, the AUCs were not significantly different from those of most biomarkers. CONCLUSIONS The identified biomarkers are able to predict mortality with moderate to good accuracy in CAP. However, biomarkers have no clear advantage over CAP-specific scores for predicting mortality.

Abstract
BACKGROUND Pentraxin 3 (PTX-3) is an acute-phase protein that increases in the plasma during inflammation. OBJECTIVE We aimed to evaluate the usefulness of PTX-3 as a clinical marker in children with lower respiratory tract infection (LRTI) and examine the correlation of PTX-3 with other biomarkers such as C-reactive protein (CRP) and procalcitonin (PCT). METHODS We enrolled 117 consecutive patients admitted to Seoul St. Mary's Hospital with LRTI using the WHO criteria. We recorded data on fever duration and peak temperature before admission, duration of fever after admission, respiratory rate, heart rate, oxygen saturation upon admission, duration of oxygen supplementation, and duration of hospital stay. Upon admission, white blood cell (WBC) count, erythrocyte sedimentation rate, CRP level were measured. Multiplex respiratory virus polymerase chain reaction was performed using nasal swabs. PTX-3, PCT, and various cytokines were measured after the study had been completed. RESULTS We found that there was no significant difference in the level of PTX-3 according to the type of viral infection. PTX-3 levels showed a significant correlation with PCT levels, but not with levels of CRP. The level of PTX-3 showed a significant correlation with peak temperature and duration of fever before admission as well as interleukin (IL)-6 levels. PCT levels showed a significant correlation with IL-6 and granulocyte-colony stimulating factor levels, peak temperature, and duration of fever before admission, and duration of hospital stay. CRP levels showed a significant correlation with duration of fever before admission, total WBC count, and neutrophil count. PCT levels significantly predicted a hospital stay of 7 days or more. PTX-3, PCT, and CRP levels showed no correlation with any other clinical features. CONCLUSION PTX-3 reflected disease severity but failed to predict length of hospital stay. Further studies evaluating the use of PTX-3 as a biomarker in mild LRTI would be useful.

Abstract
The role of procalcitonin (PCT) as a biomarker for sepsis in adults is well documented, while its role in infections affecting neonatal children remains controversial. Among these infections, Community-Acquired pneumonia (CAP) has been studied extensively, because it's the second cause of death in children in developing countries, and one of the most frequent causes of hospitalization in industrialized countries. The PubMed database and the Cochrane Library were used to search for the following keywords: CAP, procalcitonin, and children. Thirteen articles were studied to determine the role of PCT in CAP management, specifically its usefulness for distinguishing pneumococcal infections from viral and unknown infections, for predicting severity and the correct antibiotic treatment. This paper focuses on the studies performed to identify the best inflammatory biomarker for CAP management. Although there is an increase in studies confirming the usefulness of PCT in CAP management in children, further studies are needed to have better understanding of its role for pediatric CAP management.

Abstract
OBJECTIVES Although the importance of serum Procalcitonin (PCT) levels at diagnosis is well established in adult Community-Acquired Pneumonia (CAP), its use remains controversial in pediatric CAP. The aim of our study is to investigate the role of PCT and C-Reactive Protein (CRP) in the assessment of pediatric CAP severity defined by the extent of consolidation on chest X-rays and the presence of pleural effusion. In this particular setting, no clinical severity score is available at present and chest X-ray, although important for diagnosis confirmation, is not recommended as routine test. DESIGN AND METHODS The study involved 119 children admitted to the Department of Pediatric Infectious Disease for radiographically documented CAP aged 1 year to 14 years, without chronic diseases. Baseline PCT, CRP and routine laboratory tests were performed on admission. RESULTS The median PCT (μg/L) and CRP (mg/L) were 0.11 (0.05–0.58) and 21.3 (4.2–48.1), respectively. PCT showed a good correlation with CRP, neutrophils and WBC (r = 0.538, P < 0.001; r = 0.377, P < 0.001; r = 0.285, P0.002, respectively). CRP, but not PCT, was associated with lobar consolidation (P = 0.007) and pleural effusion (P = 0.002). Logistic regression analysis revealed that only CRP was a predictor of lobar consolidation (OR: 1.078; 95% CI: 1.017–1.143; P = 0.011) and pleural effusion (OR: 1.076; 95% CI: 1.005–1.153; P = 0.036). CONCLUSION Our findings revealed that PCT is correlated to the main inflammatory markers in children with CAP. CRP, unlike PCT, is able to predict the extent of chest X-ray infiltration and ultimately the severity of the disease confirming its usefulness in the management of pneumonia

Abstract
BACKGROUND Sepsis is a common complication of infections, burns, traumas, surgeries, poisonings, and post-cardiopulmonary resuscitation. The present study aimed to investigate prognostic value of CD4(+)CD25(+) regulatory T cells (Treg) in peripheral blood of patients with sepsis. METHODS Periphery blood from 28 patients diagnosed with sepsis was collected on day 1 and 7 after hospitalization in the ICU of Shanghai Changzheng Hospital between December 2013 to April 2014. The blood was used for analyses of Treg ratio using flow cytometry and for analyses of blood routine test, C-reactive protein (CRP), bilirubin, procalcitonin (PCT), and coagulation. APACHE II and sequential organ failure assessment (SOFA) scores were also investigated. The results were compared between two outcome groups of survival or death to evaluate prognostic value for sepsis. RESULTS The patients had an average age of 60.36±15.03 years, APACHE II score 16.68±7.00, and SOFA score 7.18±3.78. Among the 28 patients, 12 had severe trauma (42.9%), 10 had septic shock (35.7%), and 9 (32.2%) died. The median ratio of Tregs was 2.10% (0.80%, 3.10%) in the survival group vs. 1.80% (1.15%, 3.65%) in the death group (Z=-0.148, P=0.883) on day 1; however it was significantly changed to 0.90% (0.30%, 2.80%) vs. 5.70% (2.60%, 8.30%) (Z=-2.905, P=0.004). CONCLUSION With better prospects for clinical application, dynamic monitoring of Tregs ratio in peripheral blood has potential value in predicting prognosis of sepsis.

Abstract
Pneumonia cases can vary in both severity and chest X-ray findings. Elevated C-reactive protein (CRP) levels may be an indicator of disease severity. We retrospectively evaluated factors correlated with the extent of chest X-ray infiltration both in community-acquired pneumonia (CAP) and a subgroup of cases with pneumococcal pneumonia. In a clinical study that evaluated the efficacy of sitafloxacin, 137 patients with CAP had been previously enrolled. In our study, 75 patients with pneumococcal pneumonia were identified among these 137 CAP patients. The extent of chest X-ray infiltration was scored and correlations with age, sex, body temperature, white blood cell (WBC) count, and CRP levels were analyzed using multivariate analysis with logistic regression. Significant correlations were observed between the extent of chest X-ray infiltration and CRP levels in both CAP and pneumococcal pneumonia. Our data indicates that CRP is a valuable and informative resource that could reflect the severity of pneumonia in cases of both CAP and pneumococcal pneumonia.
