Abstract
Community-acquired pneumonia (CAP) is a common illness that can lead to mortality. β-lactams are ineffective against atypical pathogen including Mycoplasma pneumoniae. We used molecular examinations to develop a decision tree to predict atypical pathogens with CAP and to examine the prevalence of macrolide resistance in Mycoplasma pneumoniae. We conducted a prospective observational study of patients aged ≥ 18 years who had fever and respiratory symptoms and were diagnosed with CAP in one of two community hospitals between December 2016 and October 2018. We assessed combinations of clinical variables that best predicted atypical pathogens with CAP by classification and regression tree (CART) analysis. Pneumonia was defined as respiratory symptoms and new infiltration recognized on chest X-ray or chest computed tomography. We analyzed 47 patients (21 females, 44.7%, mean age: 47.6 years). Atypical pathogens were detected in 15 patients (31.9%; 12 Mycoplasma pneumoniae, 3 Chlamydophila pneumoniae). Ten patients carried macrolide resistant Mycoplasma pneumoniae (macrolide resistant rate 83.3%). CART analysis suggested that factors associated with presence of atypical pathogens were absence of crackles, age < 45 years, and LD ≥ 183 U/L (sensitivity 86.7% [59.5, 98.3], specificity 96.9% [83.8, 99.9]). ur simple clinical decision rules can be used to identify primary care patients with CAP that are at risk for atypical pathogens. Further research is needed to validate its usefulness in various populations.Trial registration Clinical Trial (UMIN trial ID: UMIN000035346).

Abstract
BACKGROUND Parapneumonic pleural effusion and pleural empyema (PPE/PE) are complications of community-acquired pneumonia. The objective of this study was to analyze prehospital antibiotic therapy (PH-ABT) of children with PPE/PE and investigate its effects on clinical outcome and pathogen detection. METHODS Prospective nationwide active surveillance in Germany between October 2010 and June 2018. Children and adolescents <18 years of age with pneumonia-associated PE or PPE requiring drainage or with persistence of PPE/PE >7 days were included. RESULTS A total of 1724 children with PPE/PE were reported, of whom 556 children (32.3% of 1719 with available data) received PH-ABT. Children with PH-ABT had a shorter median hospital length of stay (15 vs. 18 days, P < 0.001), a longer time from onset of symptoms until hospital discharge (25 vs. 23 days, P = 0.002), a lower rate of intensive care unit admission (58.3% vs. 64.4%, P = 0.015) and fewer infectious complications (5.9% vs. 10.0%; P = 0.005). Bacterial pathogens in blood or pleural fluid culture were detected in 597 (34.5%) of 1513 children. Positive culture results were less frequent in children with than without PH-ABT (81/466 [17.4%] vs. 299/1005 [29.8%]; P < 0.001), whereas detection rates in pleural fluid samples by polymerase chain reaction were similar (91/181 [50.3%] vs. 220/398 [55.3%]; P = 0.263). CONCLUSIONS In children with PPE/PE, PH-ABT significantly reduced the overall rate of bacterial pathogen detection by culture, but not by polymerase chain reaction. PH-ABT was associated with a lower rate of infectious complications but did not affect the overall duration of disease. We therefore speculate that the duration of PPE/PE is mainly a consequence of an infection-induced inflammatory process, which can only partially be influenced by antibiotic treatment.

Abstract
AIM COVID-19 has caused large death tolls all over the world. Accurate diagnosis is of significant importance for early treatment. METHODS In this study, we proposed a novel PSSPNN model for classification between COVID-19, secondary pulmonary tuberculosis, community-captured pneumonia, and healthy subjects. PSSPNN entails five improvements: we first proposed the n-conv stochastic pooling module. Second, a novel stochastic pooling neural network was proposed. Third, PatchShuffle was introduced as a regularization term. Fourth, an improved multiple-way data augmentation was used. Fifth, Grad-CAM was utilized to interpret our AI model. RESULTS The 10 runs with random seed on the test set showed our algorithm achieved a microaveraged F1 score of 95.79%. Moreover, our method is better than nine state-of-the-art approaches. CONCLUSION This proposed PSSPNN will help assist radiologists to make diagnosis more quickly and accurately on COVID-19 cases.

Abstract
BACKGROUND AND OBJECTIVES Reports comparing the characteristics of patients and their clinical outcomes between community-acquired (CA) and hospital-acquired (HA) COVID-19 have not yet been reported in the literature. We aimed to characterise and compare clinical, biochemical and haematological features, in addition to clinical outcomes, between these patients. METHODS This multi-centre, retrospective, observational study enrolled 488 SARS-CoV-2 positive patients - 339 with CA infection and 149 with HA infection. All patients were admitted to a hospital within the University Hospitals of Morecambe Bay NHS Foundation Trust between March 7th and May 18th, 2020. RESULTS The CA cohort comprised of a significantly younger population, median age 75 years, versus 80 years in the HA cohort (P = 0·0002). Significantly less patients in the HA group experienced fever (P = 0·03) and breathlessness (P < 0·0001). Furthermore, significantly more patients had anaemia and hypoalbuminaemia in the HA group, compared to the CA group (P < 0·0001 for both). Hypertension and a lower median BMI were also significantly more pronounced in the HA cohort (P = 0·03 and P = 0·0001, respectively). The mortality rate was not significantly different between the two cohorts (34% in the CA group and 32% in the HA group, P = 0·64). However, the CA group required significantly greater ICU care (10% versus 3% in the HA group, P = 0·009). CONCLUSION Hospital-acquired and community-acquired COVID-19 display similar rates of mortality despite significant differences in baseline characteristics of the respective patient populations. Delineation of community- and hospital-acquired COVID-19 in future studies on COVID-19 may allow for more accurate interpretation of results.

Abstract
Background Despite recent advances in management and preventive strategies, high rates of first line antibiotics treatment failure and case fatality for Severe Community Acquired Pneumonia (SCAP) continue to occur in children in low and middle-income countries. This study aimed to identify the predictors and outcome of first line antibiotics treatment failure among children under-five years of age with SCAP admitted at Bugando Medical Centre (BMC) in Mwanza, Tanzania. Methods The study involved under-five children admitted with SCAP, treated with first line antibiotics as recommended by WHO. Patients with treatment failure at 48 hours were shifted to second line of antibiotics treatment and followed up for 7 days. Generalized linear model was used to determine predictors of first line antibiotics treatment failure for SCAP. Results A total of 250 children with SCAP with a median age of 18 [IQR 9–36] months were enrolled, 8.4% had HIV infection and 28% had acute malnutrition. The percentage of first line antibiotics treatment failure for the children with SCAP was 50.4%. Predictors of first line treatment failure were; presentation with convulsion (RR 1.55; 95% CI [1.11–2.16]; p-value 0.009), central cyanosis (RR 1.55; 95% CI [1.16–2.07]; p-value 0.003), low oxygen saturation (RR 1.28; 95% CI [1.01–1.62]; p-value 0.04), abnormal chest X-ray (RR 1.71; 95% CI [1.28–2.29]; p-value <0.001), HIV infection (RR 1.80; 95% CI [1.42–2.27]; p-value 0.001), moderate acute malnutrition (RR 1.48; 95% CI [1.04–2.12]; p-value = 0.030) and severe acute malnutrition (RR 2.02; 95% CI [1.56–2.61]; p-value<0.001). Mortality in children who failed first line treatment was 4.8%. Conclusion Half of the children with SCAP at this tertiary center had first line antibiotics treatment failure. HIV infection, acute malnutrition, low oxygen saturation, convulsions, central cyanosis, and abnormal chest X-ray were independently predictive of first line treatment failure. We recommend consideration of second line treatment and clinical trials for patients with SCAP to reduce associated morbidity and mortality.

Abstract
OBJECTIVE Coronavirus disease 2019 (COVID-19) has high morbidity and mortality, and spreads rapidly in the community to result in a large number of infection cases. This study aimed to compare clinical features in adult patients with coronavirus disease 2019 (COVID-19) pneumonia to those in adult patients with community-acquired pneumonia (CAP). METHODS Clinical presentations, laboratory findings, imaging features, complications, treatment and outcomes were compared between patients with COVID-19 pneumonia and patients with CAP. The study group of patients with COVID-19 pneumonia consisted of 120 patients. One hundred and thirty-four patients with CAP were enrolled for comparison. RESULTS Patients with COVID-19 pneumonia had lower levels of abnormal laboratory parameters (white blood cell count, lymphocyte count, procalcitonin level, erythrocyte sedimentation rate and C-reactive protein level) and more extensive radiographic involvement. More severe respiratory compromise resulted in a higher rate of intensive care unit admission, acute respiratory distress syndrome (ARDS) and mechanical ventilation (36% vs 15%, 34% vs 15% and 32% vs 12%, respectively; all p < .05). The 30 day mortality was more than twice as high in patients with COVID-19 pneumonia (12% versus 5%; p = .063), despite not reaching a statistically significant difference. CONCLUSIONS Lower levels of abnormal laboratory parameters, more extensive radiographic involvement, more severe respiratory compromise, and higher rates of ICU admission, ARDS and mechanical ventilation are key characteristics that distinguish patients with COVID-19-associated pneumonia from patients with CAP.

Abstract
Complicated community-acquired pneumonia in a previously well child is a severe illness characterised by combinations of local complications (eg, parapneumonic effusion, empyema, necrotising pneumonia, and lung abscess) and systemic complications (eg, bacteraemia, metastatic infection, multiorgan failure, acute respiratory distress syndrome, disseminated intravascular coagulation, and, rarely, death). Complicated community-acquired pneumonia should be suspected in any child with pneumonia not responding to appropriate antibiotic treatment within 48-72 h. Common causative organisms are Streptococcus pneumoniae and Staphylococcus aureus. Patients have initial imaging with chest radiography and ultrasound, which can also be used to assess the lung parenchyma, to identify pleural fluid; CT scanning is not usually indicated. Complicated pneumonia is treated with a prolonged course of intravenous antibiotics, and then oral antibiotics. The initial choice of antibiotic is guided by local microbiological knowledge and by subsequent positive cultures and molecular testing, including on pleural fluid if a drainage procedure is done. Information from pleural space imaging and drainage should guide the decision on whether to administer intrapleural fibrinolytics. Most patients are treated by drainage and more extensive surgery is rarely needed; in any event, in low-income and middle-income countries, resources for extensive surgeries are scarce. The clinical course of complicated community-acquired pneumonia can be prolonged, especially when patients have necrotising pneumonia, but complete recovery is the usual outcome.

Abstract
RATIONALE Invasive community-acquired infections, including pyogenic liver abscesses, caused by hypervirulent Klebsiella pneumoniae (hvKp) strains have been well recognized worldwide. Among these, sporadic hvKp-related community-acquired pneumonia (CAP) is an acute-onset, rapidly progressing disease that can likely turn fatal, if left untreated. However, the clinical diagnosis of hvKp infection remains challenging due to its non-specific symptoms, lack of awareness regarding this disease, and no consensus definition of hvKp. PATIENT CONCERNS A 39-year-old man presented with high-grade fever and sudden-onset chest pain. Laboratory testing revealed an elevated white blood cell count of 11,600 cells/μl and C-reactive protein level (>32 mg/dl). A chest X-ray and computed tomography revealed a focal consolidation in the left lower lung field. DIAGNOSIS Diagnosis of fulminant CAP caused by a hvKp K2-ST86 strain was made based upon multilocus sequencing typing (MLST). INTERVENTIONS The patient was treated with ampicillin/sulbactam. OUTCOMES The pneumonia became fulminant. Despite intensive care and treatment, he eventually died 15.5 hours after admission. LESSONS This is the first case of fatal fulminant CAP caused by a hvKp K2-ST86 strain reported in Japan. MLST was extremely useful for providing a definitive diagnosis for this infection. Thus, we propose that a biomarker-based approach should be considered even for an exploratory diagnosis of CAP related to hvKp infection.

Abstract
OBJECTIVE The aim: To assess the metabolic by-products of nitric oxide in peripheral blood before and after the medicamentous management in patients suffering from community-acquired pneumonia associated with coronary heart disease. PATIENTS AND METHODS Materials and methods: We have examined 102 patients with community-acquired pneumonia aged from 50 to 65 years, of which 58 patients were diagnosed with coronary heart disease (CHD). The complex treatment of patients with coronary heart disease was supplemented by the additional use of tivortin aspartate, which was taken orally with food at the dose of 5 ml (1g) 3 times a day for 15 days. The NO content in blood plasma was assessed by the concentration of the amount of final NO metabolites (NO3 + NO2), identified by means of the photocalorimetric method. RESULTS Results: The content of (NO3 + NO2) in peripheral blood of patients with CAP was slightly higher (6.83 ± 0.29) μmol/l as compared to the group of apparently healthy individuals (5.19 ± 0.14) μmol/l, while in patients with CAP associated with CHD it has markedly increased to (12.74 ± 1.09) μmol/l. Against the background of administered treatment, the index of (NO3 + NO2) in patients with coronary heart disease has decreased to (5.76 ± 0.33) μmol/l, while in the group of patients who were not given tivortin aspartate additionally, this index has even slightly increased (7.01 ± 0.40) μmol/l. CONCLUSION Conclusions: Marked increase of (NO3 + NO2) levels in blood pointed to destabilization of the course of coronary heart disease with CAP, which was eliminated by the involvement of tivortin aspartate (15 days) to the main course of treatment.

Abstract
BACKGROUND Diabetes is one of the underlying risk factors for developing community-acquired pneumonia (CAP). The high prevalence of diabetes among population and the rising incidence of this illness, converts it as an important disease to better control and manage, to prevent its secondary consequences as CAP. The objective of this research is to describe the characteristics of the patients with diabetes and the differences with the no diabetes who have had an episode of CAP in the context of the primary care field. METHODS A retrospective, observational study in adult patients (> 18 years-old) who suffer from CAP and attended at primary care in Spain between 2009 and 2013 was developed using the Computerized Database for Pharmacoepidemiological Studies in Primary Care (BIFAP). We carried out a descriptive analysis of the first episodes of CAP, in patients with or without diabetes as comorbidity. Other morbidity (CVA, Anaemia, Arthritis, Asthma, Heart disease, Dementia, Depression, Dysphagia, Multiple sclerosis, Epilepsy, COPD, Liver disease, Arthrosis, Parkinson's disease, Kidney disease, HIV) and life-style factors were also included in the study. RESULTS A total of 51,185 patients were included in the study as they suffer from the first episode of CAP. Of these, 8012 had diabetes as comorbidity. There were differences between sex and age in patients with diabetes. Patients without diabetes were younger, and had less comorbidities including those related to lifestyles such as smoking, alcoholism, social and dental problems than patients with diabetes. CONCLUSIONS Patients who developed an episode of CAP with diabetes have more risk factors which could be reduced with an appropriate intervention, including vaccination to prevent successive CAP episodes and hospitalization. The burden of associated factors in these patients can produce an accumulation of risk. Health care professional should know this for treating and control these patients in order to avoid complications. Diabetes and those other risk factors associated could be reduced with an appropriate intervention, including vaccination to prevent the first and successive CAP episodes and the subsequent hospitalization in severe cases.

Abstract
BACKGROUND Community-acquired pneumonia (CAP) is a major global disease. Parapneumonic effusions often complicate CAP and range from uninfected (simple) to infected (complicated) parapneumonic effusions and empyema (pus). CAP patients who have a pleural effusion at presentation are more likely to require hospitalization, have a longer length of stay and higher mortality than those without an effusion. Conventional management of pleural infection, with antibiotics and chest tube drainage, fails in about 30% of cases. Several randomized controlled trials (RCT) have evaluated the use of corticosteroids in CAP and demonstrated some potential benefits. Importantly, steroid use in pneumonia has an acceptable safety profile with no adverse impact on mortality. A RCT focused on pediatric patients with pneumonia and a parapneumonic effusion demonstrated shorter time to recovery. The effects of corticosteroid use on clinical outcomes in adults with parapneumonic effusions have not been tested. We hypothesize that parapneumonic effusions develop from an exaggerated pleural inflammatory response. Treatment with systemic steroids may dampen the inflammation and lead to improved clinical outcomes. The steroid therapy and outcome of parapneumonic pleural effusions (STOPPE) trial will assess the efficacy and safety of systemic corticosteroid as an adjunct therapy in adult patients with CAP and pleural effusions. METHODS STOPPE is a pilot multicenter, double-blinded, placebo-controlled RCT that will randomize 80 patients with parapneumonic effusions (2:1) to intravenous dexamethasone or placebo, administered twice daily for 48 hours. This exploratory study will capture a wide range of clinically relevant endpoints which have been used in clinical trials of pneumonia and/or pleural infection; including, but not limited to: time to clinical stability, inflammatory markers, quality of life, length of hospital stay, proportion of patients requiring escalation of care (thoracostomy or thoracoscopy), and mortality. Safety will be assessed by monitoring for the incidence of adverse events during the study. DISCUSSION STOPPE is the first trial to assess the efficacy and safety profile of systemic corticosteroids in adults with CAP and pleural effusions. This will inform future studies on feasibility and appropriate trial endpoints. TRIAL REGISTRATION ACTRN12618000947202 PROTOCOL VERSION:: version 3.00/26.07.18.

Severe-febrile-illness (SFI) is a common cause of morbidity and mortality across sub-Saharan Africa (SSA). The burden of SFI in SSA is currently unknown and its estimation is fraught with challenges. This is due to a lack of diagnostic capacity for SFI in SSA, and thus a dearth of baseline data on the underlying etiology of SFI cases and scant SFI-specific causative-agent prevalence data. To highlight the public health significance of SFI in SSA, we developed a Bayesian model to quantify the incidence of SFI hospital admissions in SSA. Our estimates indicate a mean population-weighted SFI-inpatient-admission incidence rate of 18.4 (6.8–31.1, 68% CrI) per 1000 people for the year 2014, across all ages within areas of SSA with stable Plasmodium falciparum transmission. We further estimated a total of 16,200,337 (5,993,249–27,321,779, 68% CrI) SFI hospital admissions. This analysis reveals the significant burden of SFI in hospitals in SSA, but also highlights the paucity of pathogen-specific prevalence and incidence data for SFI in SSA. Future improvements in pathogen-specific diagnostics for causative agents of SFI will increase the abundance of SFI-specific prevalence and incidence data, aid future estimations of SFI burden, and enable clinicians to identify SFI-specific pathogens, administer appropriate treatment and management, and facilitate appropriate antibiotic use.

Abstract
OBJECTIVE To examine predefined risk factors and outcome of seizures in community-acquired bacterial meningitis (CABM). DESIGN Observational cohort studies SETTING: Denmark PARTICIPANTS: In the derivation cohort, we retrospectively included all adults (>15 years of age) with CABM in North Denmark Region from 1998 to 2014 and at Hvidovre and Hillerød hospitals from 2003 to 2014. In the validation cohort, we prospectively included all adults (>18 years of age) with CABM treated at all departments of infectious diseases in Denmark from 2015 to 2017. PRIMARY AND SECONDARY OUTCOME MEASURES In the derivation cohort, we used modified Poisson regression to compute adjusted relative risks (RRs) with 95% confidence intervals for predefined risk factors for seizures during CABM as well as for risks of death and unfavourable outcome assessed by the Glasgow Outcome Scale score (1-4). Next, results were validated in the validation cohort. RESULTS In the derivation cohort (n=358), risk factors for seizures at any time were pneumococcal aetiology (RR 1.69, 1.01-2.83) and abnormal cranial imaging (RR 2.27, 1.46-3.53), while the impact of age >65 years and immunocompromise was more uncertain. Examining seizures occurring after admission, risk factors were abnormal cranial imaging (RR 2.23, 1.40-3.54) and immunocompromise (RR 1.59, 1.01-2.50). Seizures at any time were associated with increased risks of in-hospital mortality (RR 1.45, 1.01-2.09) and unfavourable outcome at discharge (RR 1.27, 1.02-1.60). In the validation cohort (n=379), pneumococcal aetiology (RR 1.69, 1.10-2.59) and abnormal cranial imaging (RR 1.68, 1.09-2.59) were confirmed as risk factors for seizures at any time. For seizures occurring after admission, only pneumococcal meningitis (RR 1.92, 1.12-3.29) remained significant. Seizures at any time were also associated with in-hospital mortality (RR 3.26, 1.83-5.80) and unfavourable outcome (RR 1.23, 1.00-1.52) in this cohort. CONCLUSIONS Pneumococcal aetiology, immunocompromise and abnormal cranial imaging were risk factors for seizures in CABM. Seizures were strongly associated with mortality and unfavourable outcome.

Abstract
Objectives To determine whether the impact of a thoracic CT scan on community-acquired pneumonia (CAP) diagnosis and patient management varies according to emergency physician’s experience (≤10 vs >10 years). Methods Early thoracic CT Scan for Community-Acquired Pneumonia at the Emergency Department is an interventional study conducted from November 2011 to January 2013 in four French emergency departments, and included suspected patients with CAP. We analysed changes in emergency physician CAP diagnosis classification levels before and after CT scan; and their agreement with an adjudication committee. We performed univariate analysis to determine the factors associated with modifying the diagnosis classification level to be consistent with the radiologist’s CT scan interpretation. Results 319 suspected patients with CAP and 136 emergency physicians (75% less experienced with ≤10 years, 25% with >10 years of experience) were included. The percentage of patients whose classification was modified to become consistent with CT scan radiologist’s interpretation was higher among less-experienced than experienced emergency physicians (54.2% vs 40.2%; p=0.02). In univariate analysis, less emergency physician experience was the only factor associated with changing a classification to be consistent with the CT scan radiologist’s interpretation (OR 1.77, 95% CI 1.01 to 3.10, p=0.04). After CT scan, the agreement between emergency physicians and adjudication committee was moderate for less-experienced emergency physicians and slight for experienced emergency physicians (k=0.457 and k=0.196, respectively). After CT scan, less-experienced emergency physicians modified patient management significantly more than experienced emergency physicians (36.1% vs 21.7%, p=0.01). Conclusions In clinical practice, less-experienced emergency physicians were more likely to accurately modify their CAP diagnosis and patient management based on thoracic CT scan than more experienced emergency physicians.

Abstract
IMPORTANCE Patients with alcohol use disorder (AUD) are at elevated risk of developing pneumonia, but few studies have assessed the outcomes of pneumonia in patients with AUD. OBJECTIVES To compare the causes, treatment, and outcomes of pneumonia in patients with and without AUD and to understand the associations of comorbid illnesses, alcohol withdrawal, and any residual effects due to alcohol itself with patient outcomes. DESIGN, SETTING, AND PARTICIPANTS A retrospective cohort study was conducted of 137 496 patients 18 years or older with pneumonia who were admitted to 177 US hospitals participating in the Premier Healthcare Database from July 1, 2010, to June 30, 2015. Statistical analysis was conducted from October 27, 2017, to August 20, 2018. EXPOSURE Alcohol use disorders identified from International Classification of Diseases, Ninth Revision, Clinical Modification codes. MAIN OUTCOMES AND MEASURES Pneumonia cause, antibiotic treatment, inpatient mortality, clinical deterioration, length of stay, and cost. Associations of AUD with these variables were studied using generalized linear mixed models. RESULTS Of 137 496 patients with community-acquired pneumonia (70 358 women and 67 138 men; mean [SD] age, 69.5 [16.2] years), 3.5% had an AUD. Patients with an AUD were younger than those without an AUD (median age, 58.0 vs 73.0 years; P < .001), more often male (77.3% vs 47.8%; P < .001), and more often had principal diagnoses of aspiration pneumonia (10.9% vs 9.8%; P < .001), sepsis (38.6% vs 30.7%; P < .001), or respiratory failure (9.3% vs 5.5%; P < .001). Their cultures more often grew Streptococcus pneumoniae (43.7% vs 25.5%; P < .001) and less frequently grew organisms resistant to guideline-recommended antibiotics (25.0% vs 43.7%; P < .001). Patients with an AUD were treated more often with piperacillin-tazobactam (26.2% vs 22.5%; P < .001) but equally as often with anti-methicillin-resistant Staphylococcus aureus agents (32.9% vs 31.8%; P = .11) compared with patients without AUDs. When adjusted for demographic characteristics and insurance, AUD was associated with higher mortality (odds ratio, 1.40; 95% CI, 1.25-1.56), length of stay (risk-adjusted geometric mean ratio, 1.24; 95% CI, 1.20-1.27), and costs (risk-adjusted geometric mean ratio, 1.33; 95% CI, 1.28-1.38). After additional adjustment for differences in comorbidities and risk factors for resistant organisms, AUD was no longer associated with mortality but remained associated with late mechanical ventilation (odds ratio, 1.28; 95% CI, 1.12-1.46), length of stay (risk-adjusted geometric mean ratio, 1.04; 95% CI, 1.01-1.06), and costs (risk-adjusted geometric mean ratio, 1.06; 95% CI, 1.03-1.09). Models segregating patients undergoing alcohol withdrawal showed that poorer outcomes among patients with AUD were confined to the subgroup undergoing alcohol withdrawal. CONCLUSIONS AND RELEVANCE This study suggests that, compared with hospitalized patients with community-acquired pneumonia but without AUD, those with AUD less often harbor resistant organisms. The higher age-adjusted risk of death among patients with AUD appears to be largely attributable to differences in comorbidities, whereas greater use of health care resources may be attributable to alcohol withdrawal.

Abstract
BACKGROUND The Mortality in Emergency Department Sepsis (MEDS) score can be used to stratify ED patients with suspected infections according to mortality risk. However, it has yet to be externally validated for patients having bloodstream infections. METHODS We retrospectively computed clinical information for the MEDS score, Pitt bacteremia score (PBS), Charlson comorbidity index (CCI), and McCabe-Jackson comorbid classification (MJCC) for adults with community-onset bacteremia. The MEDS score was validated by the comparisons with the following scoring systems: the PBS, CCI, MJCC, PBS plus MJCC, and PBS plus CCI. We evaluated goodness-of-fit statistics and c-statistics as measures of model calibration and discrimination, respectively. RESULTS Of 2328 adults, a good calibration for 28-day crude mortality was obtained only in the MEDS score and PBS plus MJCC; a higher c-statistic (0.870, P < 0.001) were achieved by the MEDS score, compared to the PBS, CCI MJCC, PBS plus MJCC, and PBS plus CCI. A high c-statistic was observed in two combinative scoring system: the PBS plus CCI (0.855, P < 0.001) and PBS plus MJCC (0.843, P < 0.001). According to the Kaplan-Meier curves, 28-day crude mortality significantly differed between patients with scores equal to or higher than selected cutoff values and those with scores lower than selected cutoff values: 10 in the MEDS score and 5 in the PBS plus MJCC, respectively. CONCLUSION The MEDS score is an excellent predictor of short-term outcomes in patients with community-onset bacteremia because it provides estimates with higher calibration and discrimination than those of the other scoring systems.

Abstract
BACKGROUND CAP (Community acquired pneumonia) is frequent, with a high mortality rate and a high burden on health care systems. Development of predictive biomarkers, new therapeutic concepts, and epidemiologic research require a valid, reproducible, and quantitative measure describing CAP severity. METHODS Using time series data of 1532 patients enrolled in the PROGRESS study, we compared putative measures of CAP severity for their utility as an operationalization. Comparison was based on ability to correctly identify patients with an objectively severe state of disease (death or need for intensive care with at least one of the following: substantial respiratory support, treatment with catecholamines, or dialysis). We considered IDSA/ATS minor criteria, CRB-65, CURB-65, Halm criteria, qSOFA, PSI, SCAP, SIRS-Score, SMART-COP, and SOFA. RESULTS SOFA significantly outperformed other scores in correctly identifying a severe state of disease at the day of enrollment (AUC = 0.948), mainly caused by higher discriminative power at higher score values. Runners-up were the sum of IDSA/ATS minor criteria (AUC = 0.916) and SCAP (AUC = 0.868). SOFA performed similarly well on subsequent study days (all AUC > 0.9) and across age groups. In univariate and multivariate analysis, age, sex, and pack-years significantly contributed to higher SOFA values whereas antibiosis before hospitalization predicted lower SOFA. CONCLUSIONS SOFA score can serve as an excellent operationalization of CAP severity and is proposed as endpoint for biomarker and therapeutic studies.

Performance of the CHA 2DS 2-VASc score in predicting new onset atrial fibrillation during hospitalization for community-acquired pneumonia. Eur J Intern Med 2019; 62:24-28.

Abstract
BACKGROUND Cardiovascular events are common during hospitalization for community-acquired pneumonia (CAP), with new onset atrial fibrillation (NOAF) being the second most relevant complication. In this study, we aimed to investigate the role of CHA2DS2-VASc score in predicting NOAF during hospitalization for CAP. METHODS Patients admitted for CAP were prospectively assessed using CHA2DS2-VASc. The end-point of the study was the occurrence of any objectively documented episode of NOAF during hospitalization in patients that were in sinus rhythm at hospital admission. RESULTS Of 468 patients enrolled (median age 76 years), 48 (10.3%) experienced NOAF during hospitalization. They were older, had more comorbidities, more severe pneumonia, and higher CHA2DS2-VASc than those who remained in sinus rhythm (4.4 ± 1.6 vs 3.4 ± 1.9, respectively; p < .0001). There was a direct relationship between CHA2DS2-VASc score and risk of NOAF. At ROC curve analysis, a CHA2DS2-VASc score > 3 was the most accurate cut-off for prediction of NOAF (AUC 0.653; 95% CI 0.577-0.729; p = .001). In two different multivariable models, each CHA2DS2-VASc point increase and a score > 3 both were independently associated with NOAF (HR 1.3; 95% CI 1.09-1.55; p = .003 and 2.3; 95% CI 1.19-4.44; p = .007, respectively). CONCLUSIONS CHA2DS2-VASc score is an accurate and independent predictor of NOAF in patients with CAP, and a score > 3 features a population at high risk of developing the arrhythmia during hospitalization. This simple and effective tool should be incorporated in the evaluation of patients hospitalized for CAP, with implications ranging from arrhythmic prevention to anticoagulation management.

Abstract
BACKGROUND Non-alcoholic fatty liver disease (NAFLD) is a common and serious form of chronic liver disease. Risk factors of NAFLD include obesity and type 2 diabetes which are associated with infections. AIM We aimed to determine the association of NAFLD with 30-day all-cause mortality in adult patients with community-acquired pneumonia (CAP). METHODS A retrospective cohort study on hospitalized patients with CAP that was conducted during a period of 4 years. We included patients aged ≥18 years with CAP who underwent abdominal ultrasonography. We compared between patients with and without NAFLD in term of age, gender, body mass index (BMI), comorbidities, CURB-65, pneumonia severity index (PSI), liver enzymes, C-reactive protein (CRP) and 30-day all-cause mortality. We used fibrosis score to distinguish between patients with NAFLD who have advanced fibrosis (F3-F4) and do not have (F0-F2). RESULTS A total of 561 patients were included in this study. The overall prevalence of NAFLD was 200/561 (35.6%). Significant differences were found between the groups with and without NAFLD in term of BMI, CURB-65, ALT, GGT and CRP. The 30-day all-cause mortality rate was 9.8% (55/561). Among the NAFLD group 34/200 (17%) subjects died vs. 21/361 (5.82%) among patients without NAFLD, P < 0.001. Multi-variate logistic regression analysis after adjusting for other multiple covariates showed that NAFLD with fibrosis score 0-2 [odds ratio (OR) 1.38, 95% confidence interval (CI) 1.12-1.51, P = 0.04], NAFLD with fibrosis score> 2 (1.52; 1.25-1.70, P = 0.03) were associated with 30-day all-cause mortality among patients with CAP. CONCLUSIONS NAFLD was associated with 30-day all-cause mortality in patients with CAP. This association was more significant in patients with advanced hepatic fibrosis.

Abstract
The aim of the study was to determin the incidence, severity and prognostic significance of acute kidney injury (AKI) in elderly patients with community-acquired pneumonia (CAP). 122 older patients (≥60 years) with community-acquired pneumonia were examined. Acute kidney injury was diagnosed in 49 (40,2%) patients including 47 (95,9%) patients with AKI occurring prehospital. In patients with community-acquired pneumonia associated with acute kidney injury the clinical picture of AKI was harder. Also disturbance of consciousness, dyspnea, leg swelling, tachycardia, abnormal liver function tests such as hyperbilirubinemia and hypertransaminasemia were diagnosed more frequently in this group of patients. With the development of AKI increased in-hospital mortality: odds ratio of death among patients with CAP associated with AKI was 8,3 (95% CI 2,75-25,28). So, the development of AKI in elderly patients with CAP is an actual health problem requiring the development of preventive measures and drug therapy in patients with CAP and also mandatory monitoring of patients who have had acute kidney injury.

Abstract
AIM To evaluate prior prevalence of HIV indicator conditions in late-presenters with HIV infection. DESIGN Retrospective cohort study between 2000 and 2014 in a healthcare network in Melbourne, Australia comparing patients presenting with late diagnosis of HIV infection (CD4 < 350 cells/ml) to those patients who had a CD greater than or equal to 350 cells/ml at presentation. METHOD The European AIDS Clinical Society guidelines on HIV indicator guided testing were used to assess for any indicator conditions in their prior medical history which may have represented a missed opportunity for earlier diagnosis. Main outcome measures: Descriptive statistics and prevalence of HIV indicator conditions. RESULTS Of 436 patients with HIV infection, 82 were late presenters. Late presenters were more commonly male (83% vs. 75%, P = 0.11), older (mean age 45 vs. 39 years), born overseas (61% vs. 58%, P = 0.68) and report heterosexual transmission as their exposure risk (51% vs. 31%, P < 0.001). Of 80 patients with late presentation of HIV infection, 54 (55%) had at least one, 29 (36%) at least 2, 12 (15%) at least 3 and 5 (6%) had 4 or more previous HIV indicator conditions which would have triggered HIV testing according to guidelines. The most common indicator conditions were: unexplained loss of weight (31%), herpes zoster (10%), thrombocytopenia or leukopenia (10%), oral or oesophageal candidiasis (10%) and community acquired pneumonia (9%). Twenty patients (25%) had HIV indicator conditions diagnosed at least 12 months before the eventual diagnosis of HIV infection. DISCUSSION/ CONCLUSION Patients diagnosed with late-presenting HIV often had an HIV indicator condition prior to presentation, presenting a missed opportunity for earlier diagnosis.
