INTRODUCTION: Evaluations of behavior change interventions aimed at improving professional practice are increasingly focused on impacts at the practice and patient outcome levels. Many of these evaluations assume that if the intended changes occur, the result represents an improvement. However, given the systemic nature of clinical practice, a change in one area can produce changes in other areas as well, some of which may adversely affect the patient. Balancing measures are used to determine whether unintended consequences of an intervention have been introduced into other areas of the system...

Here we describe the development, characterization and biological testing of a new type of linear molecularly imprinted polymer (LMIP) designed to act as anti-infective by blocking the quorum sensing (QS) mechanism and so preventing virulence of the pathogen Streptococcus pneumoniae. The LMIP is prepared (polymerized) in presence of a template molecule, but unlike in traditional molecular imprinting approaches no cross-linker is used. This results in soluble low molecular weight polymer that can act as drug agent in vitro and in vivo...

Patients receiving mechanical ventilation are at risk of developing ventilator-associated pneumonia. Here, we show that clinically utilized ventilation protocols in rat with 5 or 8 mL/kg tidal volumes cause increased IL-4 expression, lowered ratio of TH1:TH2 transcriptional factors (Tbet:Gata3) and increased arginase1-positive (Arg1+) macrophages and eosinophils in lungs. Macrophages from ventilated lungs had reduced ex vivo capacity towards phagocytosing bacteria. Ventilated animals, when further challenged with bacterial pneumonia, continued to show persistence of Arg1+ M2 macrophages as well as an increased bacterial burden compared to spontaneously breathing animals receiving the same bacterial dose...

We evaluated the relationship between initial antibiotic therapy and clinical outcomes in 5005 patients with microbiologically confirmed infections due to Streptococcus pneumoniae. In multivariable analysis, the receipt of "discordant" empiric antibiotic therapy was not associated with 30-day mortality (Hazard Ratio 0.94, 95% CI 0.67-1.32).

Strongyloides stercoralis is an intestinal nematode that can cause disseminated infection in an immunocompromised host. It is most commonly acquired in developing countries. It was previously a common infection in many parts of the United States, particularly in the Appalachian region, but is rarely identified currently. Here, we describe a patient born and raised in Appalachia, with no history of travel outside the United States, who presented with chronic lymphocytic leukemia and S. stercoralis hyperinfection characterized by acute respiratory failure, altered mental status, and extended-spectrum-beta-lactamase Klebsiella pneumoniae bacteremia...

OBJECTIVE: A substantial proportion of cases of usual interstitial pneumonia (UIP) are due to connective tissue disease (CTD)-associated interstitial lung disease (ILD). The purpose of this study was to determine whether specific CT findings can help differentiate a UIP pattern of CTD-ILD from a UIP pattern of idiopathic pulmonary fibrosis (IPF) and whether these signs are associated with survival. MATERIALS AND METHODS: Adults visiting an ILD clinic from 2006 to 2015 enrolled in a research registry with a multidisciplinary diagnosis of CTD-ILD or IPF and a UIP pattern at high-resolution CT were included in the study...

AIMS: Diuretic drugs may theoretically improve respiratory health outcomes in COPD through several possible mechanisms, but they might also lead to respiratory harm. We evaluated the association of incident oral diuretic drug use with respiratory-related morbidity and mortality among older adults with COPD. METHODS: This was a population-based, retrospective cohort study using health administrative data from Ontario, Canada, for the period 2008-2013. We identified adults aged 66 years and older with non-palliative COPD using a validated algorithm...

AIM: Pneumonia is one of the major causes of mortality in older adults. As the average lifespan has extended and new modalities to prevent or treat pneumonia are developed, the factors that affect the length of hospital stay (LHS) and in-hospital mortality of older patients with pneumonia have changed. The object of the present study was to determine the factors associated with LHS and mortality as a result of pneumonia among older patients with dementia. METHODS: With a retrospective cohort study design, we used the data derived from the Japanese Administrative Database and diagnosis procedure combination/per diem payment system (DPC/PDPS) database...

Stenotrophomonas maltophilia (SM) has emerged as an important nosocomial pathogen with high morbidity and mortality. Because of its unique antimicrobial susceptibility pattern, appropriate antimicrobial therapy for SM bacteremia is still challenging, especially in immunocompromised patients. The present study was performed to assess clinical predictors of SM bacteremia in adult patients with hematologic malignancy. From 2006 through 2016, a case-control study was performed at a tertiary-care hospital. Case patients were defined as SM bacteremia in patients with hematologic malignancy...

Urinary tract infections due to enterobacteria producing extended spectrum beta-lactamases (ESBL-E) constitute a infectious risk, a major therapeutic challenge and can even lead, in some cases, to a deadlock beacuse of their multi-resistance to antibiotics. This study aimed to determine the epidemiological profile of uropathogenic ESBL-E and to describe their current level of resistance to antibiotics for a better patient management according to local data. We conducted a retrospective study of all ESBL-E strains isolated from all cytobacteriogical testing of urine (CBEU) treated in the Microbiology Laboratory at the Military Hospital of Moulay Ismail, Meknes over a period of three years (from 1 January 2013 to 31 December 2015)...

REVIEW
So Hyeon Bak, Ho Yun Lee
Smoking-related interstitial lung disease (ILD) consists of a heterogeneous group of disorders that are considered a distinct entity. The 2013 American Thoracic Society and European Respiratory Society recommendations classified respiratory bronchiolitis (RB)/RB-ILD and desquamative interstitial pneumonia (DIP) as smoking-related idiopathic interstitial pneumonias (IIPs). The overlapping histopathological and radiological patterns of smoking-related IIPs must be considered. Overlap patterns of smoking-related IIPs are not easily classified as a single disorder...

The continued rise and spread of antimicrobial resistance among bacterial pathogens pose a serious challenge to global health. Countering antimicrobial-resistant pathogens requires a multifaceted effort that includes the discovery of novel therapeutic approaches. Here, we establish the capacity of the human CXC chemokines CXCL9 and CXCL10 to kill multidrug-resistant Gram-negative bacteria, including New Delhi metallo-beta-lactamase-1-producing Klebsiella pneumoniae and colistin-resistant members of the family Enterobacteriaceae that harbor the mobile colistin resistance protein MCR-1 and thus possess phosphoethanolamine-modified lipid A...
