Abstract
Long non-coding RNA Small Nucleolar RNA Host Gene 16 (SNHG16) has been reported to participate in Lipopolysaccharide (LPS)-induced inflammatory pathway, which contributes to pneumonia. This study was therefore conducted to explore the role of SNHG16 in pneumonia. In this study, expression of SNHG16 and microRNA (miR)-210 in pneumonia plasma samples (n = 56) and control samples (n = 60) was detected by RT-qPCR. The potential crosstalk between SNHG16 and miR-210 was analyzed by performing overexpression experiments. MSP was performed to study the role of SNHG16 in methylation of miR-210 gene. Cell apoptosis was analyzed by cell apoptosis assay. Decreased expression levels of SNHG16 and increased expression levels of miR-210 were observed in pneumonia. SNHG16 showed an inverse correlation to miR-210. LPS treatment led to downregulated SNHG16 and upregulated miR-210 in Human Bronchial Epithelial Cells (HBEpCs). In HBEpCs, SNHG16 downregulated miR-210 and increased miR-210 DNA gene methylation. Moreover, SNHG16 suppressed the role of miR-210 in cell apoptosis under LPS treatment. In conclusion, SNHG16 is downregulated in pneumonia, and it downregulates miR-210 possibly through methylation to promote lung cell apoptosis induced by LPS.

Abstract
CONTEXT Qiangli Wuhu (QLWH) mixture is a concoction approved and registered by Ningxia Medical Products Administration. It has therapeutic effects on various types of pneumonia. OBJECTIVE To clarify the mechanisms of QLWH in treating pneumonia. MATERIALS AND METHODS The potential targets of QLWH in the treatment of pneumonia were predicted by network pharmacology. Male, Institute of Cancer Research (ICR) mice were randomly divided into five groups of 12 mice, control, vehicle, QLWH (10 and 20 mg/kg) and dexamethasone (DXM), and orally treated twice daily with normal saline, QLWH or DXM. The pneumonia model was established by tracheal instillation of lipopolysaccharide (LPS). After treatment five days, ELISA, H&E staining and Western blot were used to investigate protective effects of QLWH. RESULTS Nine hundred and ninety-four active ingredients were found through network pharmacology, corresponding to 135 targets for the treatment of pneumonia; compared to the vehicle group, QLWH (10 and 20 mg/kg) significantly decreased the levels of TNF-α (14.3% and 28.8%), IL-1β (23.9% and 42.8%) and IL-6 (13.2% and 16.1%), increased the levels of IL-10 (134.3% and 172.9%); in terms of mechanism, QLWH down-regulated TLR4/NF-κB/NLRP3 axis related proteins in lung tissue of pneumonia model mice (p < 0.05). DISCUSSION AND CONCLUSIONS This study combined network pharmacology and animal experiments, providing effective evidence for the clinical promotion of QLWH. Meanwhile, it is of significance for further development.

Abstract
STUDY DESIGN Retrospective study. OBJECTIVES To analyze factors associated with major complications (MC) in patients with ankylosing spondylitis (AS) undergoing surgical management for a spine fracture. METHODS Included were all persons with spine fractures and AS in a teriary health care center between 2003 and 2019. Clinical data and MC were characterized with descriptive characteristics. Multivariable analyses were used to find factors associated with MC. RESULTS In total, 174 traumatic fracture incidents in 166 patients with AS were included, with a mean patient age of 70.7 ± 13.1 years. The main reason for spine fracture was minor trauma (79.9%). Spinal cord injuries (SCI) were described in 36.7% of cases. The majority of patients (54.6%) showed more than one fracture of the spine, with cervical fractures being the most common (50.5%). Overall, the incidences of surgical site infection, implant failure, nosocomial pneumonia (NP), and mortality were 17.2%, 9.2%, 31%, and 14.9%, respectively. ICU stay > 48 hours was associated with MC (including death). Posterior approach for spondylodesis, ICU stay > 48 hours and cervical SCI were related to MC (excluding death). Age > 70 years, NP and Charlson comorbidity index > 5 points were associated with in-hospital mortality. CONCLUSIONS Patients with AS and surgical treatment of spine fractures are at high risk for MC. Therefore, our results might give physicians better insight into the incidence and sequelae of major complications and therefore might improve patient and family expectations.

Abstract
Objectives To evaluate baseline characteristics, describe pulmonary outcomes, and identify weaning predictors for people with acute traumatic spinal cord injury (SCI) who are dependent on mechanical ventilation at admission to acute inpatient rehabilitation (AIR). Methods The retrospective study was conducted at an AIR facility in the United States. It included 91 adults with acute traumatic SCI from 2015 to 2019 who were dependent on mechanical ventilation. Results People who successfully weaned (85%) had fewer days from time of SCI to AIR admission (22 vs. 30, p = .04), higher vital capacity at admission to AIR (12 vs. 3 mL/kg predicted body weight [PBW]; p < .001), and lower (caudal) neurological injury level (p < .001) compared to those who failed weaning. The risk of pneumonia was higher in people who failed weaning compared to those who were weaned successfully (risk ratio, 5.5; 95% confidence interval [95% CI], 2.3-13). Receiver operating characteristics (ROC) curves suggest a vital capacity cutoff of 5.8 mL/kg PBW could predict weaning. The vital capacity of ≥ 5.8 mL/kg PBW is associated with 109 times higher odds (95% CI, 11-1041; p < .001) of weaning than vital capacity below that threshold. Conclusion In this retrospective study, there was an increased risk of pneumonia in people with SCI who failed weaning at discharge from AIR. Vital capacity was a better predictor of weaning from mechanical ventilation compared to the neurological level of injury, with a cutoff of 5.8 mL/kg PBW predictive of weaning success. Further research is needed on this critical topic.

Abstract
Background Preoperative education and breathing exercise training by a physiotherapist minimises pulmonary complications after abdominal surgery. Effects on specific clinical outcomes such as antibiotic prescriptions, chest imaging, sputum cultures, oxygen requirements, and diagnostic coding are unknown. Methods This post hoc analysis of prospectively collected data within a double-blinded, multicentre, randomised controlled trial involving 432 participants having major abdominal surgery explored effects of preoperative education and breathing exercise training with a physiotherapist on postoperative antibiotic prescriptions, hypoxemia, sputum cultures, chest imaging, auscultation, leukocytosis, pyrexia, oxygen therapy, and diagnostic coding, compared to a control group who received a booklet alone. All participants received standardised postoperative early ambulation. Outcomes were assessed daily for 14 postoperative days. Analyses were intention-to-treat using adjusted generalised multivariate linear regression. Results Preoperative physiotherapy was associated with fewer antibiotic prescriptions specific for a respiratory infection (RR 0.52; 95% CI 0.31 to 0.85, p = 0.01), less purulent sputum on the third and fourth postoperative days (RR 0.50; 95% CI 0.34 to 0.73, p = 0.01), fewer positive sputum cultures from the third to fifth postoperative day (RR 0.17; 95% CI 0.04 to 0.77, p = 0.01), and less oxygen therapy requirements (RR 0.49; 95% CI 0.31 to 0.78, p = 0.002). Treatment effects were specific to respiratory clinical coding domains. Conclusions Preoperative physiotherapy prevents postoperative pulmonary complications and is associated with the minimisation of signs and symptoms of pulmonary collapse/consolidation and airway infection and specifically results in reduced oxygen therapy requirements and antibiotic prescriptions.

Abstract
STUDY DESIGN Retrospective, monocentric, observational study in a tertiary health care center. OBJECTIVES To analyze prehospital and clinical findings, complications, neurological improvement and follow-up in a young person cohort with spinal cord injury (SCI) and tetraplegia according to the American Spinal Injury Association (ASIA) Impairment Scale (AIS) A to D after diving into shallow water. METHODS Included were all persons younger than 50 years with SCI after head-first diving into shallow water between June 2001 and June 2019. All persons with SCI were divided into complete tetraplegia (AIS A) and incomplete tetraplegia (AIS B, C, and D) to test differences. RESULTS A total of 59 males (98.7%) and 1 female with a mean age of 27.7 years suffered an SCI. Alcohol use was documented in 25 cases (41.7%). At the time of admission, 33 people (55%) showed a complete tetraplegia (AIS A) and 27 showed an incomplete tetraplegia with 8 AIS B (13.3%), 15 AIS C (25%), and 4 AIS D (6.7%). At the time of discharge, people with initially complete tetraplegia showed a significant improvement from admission to discharge (P ≤ .004). Persons with incomplete tetraplegia were more likely to improve their neurological status compared with complete tetraplegia patients (P ≤ .001). Especially persons with complete tetraplegia suffered from typical SCI-related problems and complications. CONCLUSIONS People with SCI and tetraplegia at the time admission show neurological improvement in 50% of the cases with an overall better outcome in persons with incomplete tetraplegia. The surgical treatment of SCI within 24 hours seems to be associated with a better neurological outcome and a lower level of tetraplegia. The incidence of SCI caused by diving into shallow water remains stable without a significant change, especially in high-risk groups. More education and prevention programs are necessary to avoid these injuries.

Abstract
INTRODUCTION Community-acquired pneumonia (CAP) and hospital-acquired pneumonia (HAP) are common complications in idiopathic inflammatory myopathy (IIM) patients, and are frequently associated with unfavorable outcome as well as prolonged antibiotic therapy. In this study, we intended to clarify whether clinical pulmonary infection score (CPIS) and multiple serum biomarkers are valuable in predicting unfavorable outcomes and prolonged antibiotic therapy in adult IIM patients complicated with CAP or HAP. METHODS Data of IIM patients with CAP or HAP who were admitted to three tertiary centers from December 2010 to November 2019 were retrospectively collected. Cox proportional hazards regression analysis and logistic regression analysis were adopted to identify risk factors for unfavorable outcomes and prolonged antibiotic therapy in these patients. The predictive values of potential predictors were assessed using receiver operating characteristic analysis. RESULTS The mortality rate was 60.6% in 109 IIM patients complicated with CAP or HAP. Myositis Disease Activity Assessment Visual Analogue Scales (MYOACT) score, CPIS and timely adjustment to antibiotics based on drug susceptibility test (DST-based antibiotic) were significantly associated with long-term outcome in these patients. With an optimal cutoff value of 6.5 and area under the curve (AUC) of 0.813, CPIS was a more satisfying predictor compared with MYOACT score. The peak C-reactive protein (CRP) level, DST-based antibiotics, and complication of interstitial lung disease (ILD) were also significantly correlated with prolonged antibiotic therapy. CONCLUSIONS IIM patients complicated with CAP or HAP frequently suffer from unfavorable outcomes. Compared with IIM disease activity, CPIS worked as a better predictor of outcome in these patients. Also, the peak CRP level during hospitalization might be valuable in predicting prolonged antibiotic therapy. The existence of ILD might impede early discontinuation of antibiotics. Timely adjustment to antibiotics based on drug susceptibility testing would decrease the mortality rate and reduce the incidence of prolonged antibiotic therapy.

Abstract
BACKGROUND ALI/ARDS is a severe lung injury leading to refractory respiratory failure, accounting for high morbidity and mortality. However, therapeutic approaches are rather limited. Targeting long non-coding RNA MALAT1 and microRNA miR-181a-5p might be potential option for ALI/ARDS intervention. OBJECTIVE We aimed to investigate the role of MALAT and miR-181a-5p in the pathogenesis of ALI/ARDS, and test the therapeutic effects of targeting MALAT and miR-181a-5p for ALI/ARDS intervention in vitro. METHODS MALAT1 and miR-181a-5p levels were measured in plasma from ALI/ARDS patients. In vitro human pulmonary microvascular endothelial cell (HPMEC) injury was induced by LPS treatment, and molecular targets of MALAT1 and miR-181a-5p were explored by molecular biology approaches, mainly focusing on cell apoptosis and vascular inflammation. Interaction between MALAT1 and miR-181a-5p was also detected. Finally, the effects of targeting MALAT1 and miR-181a-5p for ALI/ARDS intervention were validated in a rat ALI/ARDS model. RESULTS MALAT1 upregulation and miR-181a-5p downregulation were observed in ALI/ARDS patients. Transfection of mimic miR-181a-5p into HPMECs revealed decreased Fas and apoptosis, along with reduced inflammatory factors. Fas was proved to be a direct target of miR-181a-5p. Similar effects were also present upon MALAT1 knockdown. As for the interaction between MALAT1 and miR-181a-5p, MALAT1 knockdown increased miR-181a-5p expression. Knocking down of MALAT1 and miR-181a-5p could both improve the outcome in ALI/ARDS rats. CONCLUSION MALAT1 antagonism or miR-181a-5p could both be potential therapeutic strategies for ALI/ARDS. Mechanistically, miR-181a-5p directly inhibits Fas and apoptosis, along with reduced inflammation. MALAT1 negatively regulates miR-181a-5p.

Comparing outcomes of mechanical ventilation with high vs. moderate tidal volumes in tracheostomized patients with spinal cord injury in acute inpatient rehabilitation setting: a retrospective cohort study. Spinal Cord 2020; 59:618-625. [PMID: 32647326 DOI: 10.1038/s41393-020-0517-4] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/19/2020] [Revised: 07/01/2020] [Accepted: 07/01/2020] [Indexed: 11/09/2022]
Abstract
STUDY DESIGN Retrospective cohort study. OBJECTIVES The primary objective of this study was to evaluate safety and efficacy of higher tidal volumes (HVt) compared to moderate Vt (MVt) in people with spinal cord injury (SCI) admitted to acute inpatient rehabilitation (AIR) facility on mechanical ventilation via tracheostomy. SETTING AIR facility in the United States. METHODS Eighty-four adults with SCI were divided into MVt group if maximum Vt received in AIR was <15 ml/kg predicted body weight (PBW) and HVt group if maximum Vt was >15 ml/kg PBW. Primary outcomes were incidence of pneumonia and composite pulmonary adverse events (pneumonia, weaning failure, or acute care transfers due to respiratory complications). Secondary outcomes were AIR preweaning days defined as time from AIR admission to beginning of weaning, weaning days defined as days from start to end of weaning, and AIR ventilator days calculated as days on ventilator from AIR admission to discharge. RESULTS MVt was utilized in 50 patients and HVt was utilized in 34 patients. The risk of pneumonia in HVt group was 4.3 times higher [95% confidence interval (CI): 1.5-12] compared to MVt group. Odds of pulmonary adverse events in HVt group was 5.4 times higher (CI: 1.8-17) compared to MVt group. There was no difference in preweaning days, weaning days, or AIR ventilator days between the two groups. CONCLUSIONS Our data suggest that HVt is associated with increased risk of pneumonia and higher odds of pulmonary adverse events in tracheostomized patients with SCI which warrants further investigation.

Supervised machine learning for the prediction of infection on admission to hospital: a prospective observational cohort study. J Antimicrob Chemother 2020; 74:1108-1115. [PMID: 30590545 DOI: 10.1093/jac/dky514] [Citation(s) in RCA: 22] [Impact Index Per Article: 5.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/23/2018] [Revised: 10/11/2018] [Accepted: 11/14/2018] [Indexed: 01/11/2023] Open
Abstract
BACKGROUND Infection diagnosis can be challenging, relying on clinical judgement and non-specific markers of infection. We evaluated a supervised machine learning (SML) algorithm for diagnosing bacterial infection using routinely available blood parameters on presentation to hospital. METHODS An SML algorithm was developed to classify cases into infection versus no infection using microbiology records and six available blood parameters (C-reactive protein, white cell count, bilirubin, creatinine, ALT and alkaline phosphatase) from 160203 individuals. A cohort of patients admitted to hospital over a 6 month period had their admission blood parameters prospectively inputted into the SML algorithm. They were prospectively followed up from admission to classify those who fulfilled clinical case criteria for a community-acquired bacterial infection within 72 h of admission using a pre-determined definition. Predictive ability was assessed using receiver operating characteristics (ROC) with cut-off values for optimal sensitivity and specificity explored. RESULTS One hundred and four individuals were included prospectively. The median (range) cohort age was 65 (21-98) years. The majority were female (56/104; 54%). Thirty-six (35%) were diagnosed with infection in the first 72 h of admission. Overall, 44/104 (42%) individuals had microbiological investigations performed. Treatment was prescribed for 33/36 (92%) of infected individuals and 4/68 (6%) of those with no identifiable bacterial infection. Mean (SD) likelihood estimates for those with and without infection were significantly different. The infection group had a likelihood of 0.80 (0.09) and the non-infection group 0.50 (0.29) (P < 0.01; 95% CI: 0.20-0.40). ROC AUC was 0.84 (95% CI: 0.76-0.91). CONCLUSIONS An SML algorithm was able to diagnose infection in individuals presenting to hospital using routinely available blood parameters.

Abstract
OBJECTIVE To determine whether Clostridioides difficile infection (CDI) exhibits spatiotemporal interaction and clustering. DESIGN Retrospective observational study. SETTING The University of Iowa Hospitals and Clinics. PATIENTS This study included 1,963 CDI cases, January 2005 through December 2011. METHODS We extracted location and time information for each case and ran the Knox, Mantel, and mean and maximum component size tests for time thresholds (T = 7, 14, and 21 days) and distance thresholds (D = 2, 3, 4, and 5 units; 1 unit = 5-6 m). All tests were implemented using Monte Carlo simulations, and random CDI cases were constructed by randomly permuting times of CDI cases 20,000 times. As a counterfactual, we repeated all tests on 790 aspiration pneumonia cases because aspiration pneumonia is a complication without environmental factors. RESULTS Results from the Knox test and mean component size test rejected the null hypothesis of no spatiotemporal interaction (P < .0001), for all values of T and D. Results from the Mantel test also rejected the hypothesis of no spatiotemporal interaction (P < .0003). The same tests showed no such effects for aspiration pneumonia. Our results from the maximum component size tests showed similar trends, but they were not consistently significant, possibly because CDI outbreaks attributable to the environment were relatively small. CONCLUSION Our results clearly show spatiotemporal interaction and clustering among CDI cases and none whatsoever for aspiration pneumonia cases. These results strongly suggest that environmental factors play a role in the onset of some CDI cases. However, our results are not inconsistent with the possibility that many genetically unrelated CDI cases occurred during the study period.

Abstract
Significance: High-mobility group protein box 1 (HMGB1), a ubiquitous nuclear protein, regulates chromatin structure and modulates the expression of many genes involved in the pathogenesis of lung cancer and many other lung diseases, including those that regulate cell cycle control, cell death, and DNA replication and repair. Extracellular HMGB1, whether passively released or actively secreted, is a danger signal that elicits proinflammatory responses, impairs macrophage phagocytosis and efferocytosis, and alters vascular remodeling. This can result in excessive pulmonary inflammation and compromised host defense against lung infections, causing a deleterious feedback cycle. Recent Advances: HMGB1 has been identified as a biomarker and mediator of the pathogenesis of numerous lung disorders. In addition, post-translational modifications of HMGB1, including acetylation, phosphorylation, and oxidation, have been postulated to affect its localization and physiological and pathophysiological effects, such as the initiation and progression of lung diseases. Critical Issues: The molecular mechanisms underlying how HMGB1 drives the pathogenesis of different lung diseases and novel therapeutic approaches targeting HMGB1 remain to be elucidated. Future Directions: Additional research is needed to identify the roles and functions of modified HMGB1 produced by different post-translational modifications and their significance in the pathogenesis of lung diseases. Such studies will provide information for novel approaches targeting HMGB1 as a treatment for lung diseases.

Abstract
Community-acquired pneumonia (CAP) is one of the most common infectious diseases, as well as a major cause of death both in developed and developing countries, and it remains a challenge for physicians around the world. Several guidelines have been published to guide clinicians in how to diagnose and take care of patients with CAP. However, there are still many areas of debate and uncertainty where research is needed to advance patient care and improve clinical outcomes. In this review we highlight current hot topics in CAP and present updated evidence around these areas of controversy. Community-acquired pneumonia is the most frequent cause of infectious death worldwide; however, there are several areas of controversy that should be addressed to improve patient care. This review presents the available data on these topics.http://bit.ly/2ShnH7A

Abstract
Objective This study aimed to determine the serum levels of NACHT, Leucine-rich repeat (LRR), and Pyrin (PYD) domains-containing Protein 3 (NLRP3) and cathelicidin LL-37, and investigate their prognostic significance in community-acquired pneumonia (CAP). Methods The sample of this prospective study was composed of 76 consecutive patients with CAP. Demographic data and clinical characteristics were collected. Serum levels of NLRP3 and LL-37 were determined by ELISA. Spearman’s analysis was used to evaluate the correlation between NLRP3 and LL-37. Association of NLRP3 and LL-37 with 30-day survival and mortality rates was assessed using the Kaplan-Meier curve and logistic regression analysis. Results Serum NLRP3 significantly increased whereas serum LL-37 significantly decreased in patients with severe CAP. Significant correlation was observed between serum NLRP3 and LL-37 in CAP patients. Patients with higher levels of NLRP3 and lower levels of LL-37 showed lower 30-day survival rate and higher mortality compared with those with lower NLRP3 and higher LL-37 levels. Conclusion Severe CAP patients tend to present higher serum NLRP3 and lower serum LL-37, which might serve as potential biomarkers for CAP prognosis.

Abstract
AIMS To evaluate the relationship between cardiovascular diseases (CVDs) and pneumonia in the general population. METHODS This retrospective observational study included two cohorts, namely CVD (n = 28,363) and non-CVD (n = 28,363) cohorts, which were matched by propensity score and examined for cases of pneumonia. Data were obtained from 2000 to 2011. In both cohorts, pneumonia risk was measured using multivariable Cox proportional hazard models. RESULTS With the non-CVD cohort as reference, the corresponding adjusted hazard ratios (aHRs) [95% confidence intervals (CIs)] of pneumonia were 2.03 [1.77-2.31] for coronary artery disease, 4.11 [3.15-5.36] for heart failure, 3.21 [2.70-3.81] for cerebrovascular disease, 1.46 [1.07-1.98] for peripheral vascular disease, and 2.27 [2.01-2.56] for the CVD cohort. The cohort with comorbidities had a higher risk (all p < .05) of pneumonia compared with that without comorbidities, except for patients with the comorbidities of hypertension, hyperlipidemia, obesity, and liver disease. The aHR (95% CI) of pneumonia for antibiotic use was 1.26 (1.09-1.47). The aHRs of community-acquired pneumonia (CAP) and hospital-acquired pneumonia (HAP) were 3.25 (95% CI = 1.04-10.1) and 2.95 (95% CI = 2.25-3.88), respectively. The aHRs (95% CI) were 1.78 (1.05-3.03) for intensive care unit (ICU) risk and 0.98 (0.96-0.99) for length of admission. CONCLUSION Pneumonia risk was associated with CVDs, especially heart failure, regardless of age, gender, comorbidities, and antibiotic use, particularly in elderly male patients. In addition, Patients with CVDs had a higher risk of CAP and HAP. The CVD cohort had a higher frequency of ICU admissions, but shorter admission lengths.

Abstract
BACKGROUND Sepsis is life-threatening organ dysfunction caused by a dysregulated host response to infection. Early recognition and treatment are the cornerstones of management. METHODS Review of the English-language literature. RESULTS For both sepsis and septic shock "antimicrobials [should be] be initiated as soon as possible and within one hour" (Surviving Sepsis Campaign). The risk of progression from severe sepsis to septic shock increases 8% for each hour before antibiotics are started. Selection of antimicrobial agents is based on a combination of patient factors, predicted infecting organism(s), and local microbial resistance patterns. The initial drugs should have activity against typical gram-positive and gram-negative causative micro-organisms. Anaerobic coverage should be provided for intra-abdominal infections or others where anaerobes are significant pathogens. Empiric antifungal or antiviral therapy may be warranted. For patients with healthcare-associated infections, resistant micro-organisms will further complicate the choice of empiric antimicrobials. Recommendations are given for specific infections. CONCLUSION Early administration of broad-spectrum antimicrobial drugs is one of the most important, if not the most important, treatment for patients with sepsis or septic shock. Drugs should be initiated as soon as possible, and the choice of should take into account patient factors, common local pathogens, hospital antibiograms and resistance patterns, and the suspected source of infection. Antimicrobial agent therapy should be de-escalated as soon as possible.

Abstract
BACKGROUND Unplanned readmission following surgery is a quality metric that helps surgeons assess initiatives targeted at improving patient care. We utilized the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database to determine the rates, causes, and predictors of unplanned 30-day readmissions after outpatient elective hand and elbow surgery. METHODS The ACS-NSQIP database was queried using hand-and-elbow-specific Current Procedural Terminology (CPT) codes to retrospectively identify patients who had undergone outpatient hand or elbow surgery in 2012 and 2013. Patients who required an unplanned readmission to the hospital within 30 days were compared with those who were not readmitted. Preoperative patient characteristics, intraoperative variables, complications, and mortality were compared between the cohorts. Cox proportional hazard models were used to determine independent associations with 30-day unplanned readmission. RESULTS A total of 14,106 outpatient hand or elbow surgery procedures were identified between 2012 and 2013, and 169 (1.2%) of them were followed by an unplanned readmission. The leading causes of readmission included postoperative infections (19.5%), pain (4.7%), thromboembolic events (4.1%), and pulmonary complications (3.0%). The causes of approximately 1/3 of the readmissions were missing from the database, and these readmissions were likely unrelated to the principal procedure. Independent predictors of readmission included an age of 70 to 84 years (hazard ratio [HR] = 2.83, 95% confidence interval [CI] = 1.67 to 4.78), smoking (HR = 2.23, 95% CI = 1.57 to 3.18), a lower hematocrit (HR = 2.19, 95% CI = 1.38 to 3.46), renal dialysis (HR = 3.32, 95% CI = 1.60 to 6.91), and an elbow procedure (with or without a hand procedure) (HR = 2.19, 95% CI = 1.57 to 3.04). CONCLUSIONS The prevalence of unplanned readmission following outpatient hand and elbow surgery is low. Several modifiable factors, including preoperative smoking and anemia, are associated with unplanned readmission. These data may be helpful in developing quality-control initiatives to target unplanned readmissions following hand and elbow procedures. LEVEL OF EVIDENCE Therapeutic Level IV.

Abstract
Aspiration pneumonia is thought to be associated with a poor outcome in patients with community acquired pneumonia (CAP). However, there has been no systematic review regarding the impact of aspiration pneumonia on the outcomes in patients with CAP. This review was conducted using the MOOSE guidelines: Patients: patients defined CAP. Exposure: aspiration pneumonia defined as pneumonia in patients who have aspiration risk. Comparison: confirmed pneumonia in patients who were not considered to be at high risk for oral aspiration. Outcomes: mortality, hospital readmission or recurrent pneumonia. Three investigators independently identified published cohort studies from PubMed, CENTRAL database, and EMBASE. Nineteen studies were included for this systematic review. Aspiration pneumonia increased in-hospital mortality (relative risk, 3.62; 95% CI, 2.65–4.96; P < 0.001, seven studies) and 30-day mortality (3.57; 2.18–5.86; P < 0.001, five studies). In contrast, aspiration pneumonia was associated with decreased ICU mortality (relative risk, 0.40; 95% CI, 0.26–0.60; P < 0.00001, four studies). Although there are insufficient data to perform a meta-analysis on long-term mortality, recurrent pneumonia, and hospital readmission, the few reported studies suggest that aspiration pneumonia is also associated with these poor outcomes. In conclusion, aspiration pneumonia was associated with both higher in-hospital and 30-day mortality in patients with CAP outside ICU settings.

Witnessed aspiration in trauma: Frequent occurrence, rare morbidity--A prospective analysis. J Trauma Acute Care Surg 2016; 79:1030-6; discussion 1036-7.

Abstract
BACKGROUND Aspiration events (AEs) are a well-recognized complication in trauma patients and have traditionally been considered a risk factor for pneumonia. Despite this, there is no consensus on the incidence or clinical significance of AE in the trauma population. METHODS All patients admitted as trauma team activations at our Level I trauma center who were intubated in the field or on arrival from September 2013 to August 2014 were prospectively collected. Field and admission data including witnessed AEs were analyzed. Additional hospital data included imaging, associated injuries, laboratory, and clinical data. Early respiratory failure, pneumonia, and hospital mortality were collected. RESULTS During the study period, 228 patients met inclusion criteria. Median age was 35.5 years, and Injury Severity Score (ISS) was 21.0. Overall, 58 patients (25.4%) had witnessed AEs. Patients with AE had significantly higher ISS (26.0 vs. 17.0, p = 0.027) and lower Glasgow Coma Scale (GCS) score on admission (median, 4.0 vs. 7.0; p = 0.003), despite similar field GCS score (p = 0.946). Body mass index (median, 27.2 vs. 26.2; p = 0.374) and intoxication rates (86.2% vs. 83.5%, p = 0.835) were similar between groups. Early pneumonia and respiratory failure were rare in all patients and were not higher in those with AE. Although mortality was higher after AE in patients who died directly after admission (51.7% vs. 30.0%, p = 0.004), in patients who survived to intensive care unit admission, there was no longer a difference between groups and aspiration was not an independent predictor of mortality (p = 0.107) on multivariable regression analysis. CONCLUSION The rate of aspiration in trauma is high and more likely to occur in patients with increased injury burden or depressed GCS score. In patients who survive past admission, early pneumonia rates are similar, regardless of AE. These data suggest that aspiration is a marker of severe illness and is associated with but not an independent predictor of mortality. LEVEL OF EVIDENCE Prognostic/epidemiologic study, level III.

Abstract
Pseudomonas putida are ubiquitous inhabitants of soils and clinical isolates of this species have been seldom described. Clinical isolates show significant variability in their ability to cause damage to hosts because some of them are able to modulate the host’s immune response. In the current study, comparisons between the genomes of different clinical and environmental strains of P. putida were done to identify genetic clusters shared by clinical isolates that are not present in environmental isolates. We show that in clinical strains specific genes are mostly present on transposons, and that this set of genes exhibit high identity with genes found in pathogens and opportunistic pathogens. The set of genes prevalent in P. putida clinical isolates, and absent in environmental isolates, are related with survival under oxidative stress conditions, resistance against biocides, amino acid metabolism and toxin/antitoxin (TA) systems. This set of functions have influence in colonization and survival within human tissues, since they avoid host immune response or enhance stress resistance. An in depth bioinformatic analysis was also carried out to identify genetic clusters that are exclusive to each of the clinical isolates and that correlate with phenotypical differences between them, a secretion system type III-like was found in one of these clinical strains, a determinant of pathogenicity in Gram-negative bacteria.
