AIMS: To evaluate in-hospital mortality rate within 24 hours in internal medicine wards and to evaluate if it may be used as quality indicator. BACKGROUND: In-hospital mortality rate is an outcome measure which apparently reflects quality of care. There are debates on whether it may be considered a quality indicator since it is difficult to compare different case-mixes between hospitals. Research on mortality within 24 hours had not been published. METHODS: An historical prospective study was conducted including the entire internal wards admissions to the Rabin Medical Center between 1/7/14 and 30/6/15...

Although many bacteriology studies on tonsillar diseases have been completed, only a few studies investigated bacteriology of tonsillar diseases in recent years, especially in Asian children population. The aim of our study is to elucidate the bacterial flora and antibiotic sensitivity of tonsillar diseases in Chinese children. A three-center study was performed on 2994 children with or without tonsillar diseases. We compared and analyzed differences of bacterial pathogens among recurrent tonsillitis, tonsillar hypertrophy and controls...

Sialidases are key virulence factors that remove sialic acid from host cell surface glycans, thus unmasking receptors to facilitate bacterial adherence and colonization. In this study, we report the isolation and characterization of novel inhibitors of the Streptococcus pneumoniae sialidases NanA, NanB, and NanC from Myristica fragrans seeds. Of the isolated compounds (1-12), malabaricone C showed the most pneumococcal sialidases inhibition (IC50 of 0.3μM for NanA, 3.6μM for NanB, and 2.9μM for NanC). These results suggested that malabaricone C and neolignans could be potential agents for combating S...

Streptococcus pneumoniae (the pneumococcus) is a human pathogen, accounting for massive global morbidity and mortality. Although asymptomatic colonization of the nasopharynx almost invariably precedes disease, the critical determinants enabling pneumococcal progression from this niche to cause invasive disease are poorly understood. One mechanism proposed to be central to this transition involves opacity phase variation, whereby pneumococci harvested from the nasopharynx are typically transparent, while those simultaneously harvested from the blood are opaque...

Estimation of the pleural effusion's volume is an important clinical issue. The existing methods cannot assess it accurately when there is large volume of liquid in the pleural cavity and/or the patient has some other disease (e.g. pneumonia). In order to help solve this issue, the objective of this study is to develop and test a novel algorithm using B-spline and local clustering level set method jointly, namely BLL. The BLL algorithm was applied to a dataset involving 27 pleural effusions detected on chest CT examination of 18 adult patients with the presence of free pleural effusion...

The production of 1,3-propanediol (1,3-PDO) from glucose was investigated using Klebsiella pneumoniae J2B, which converts glycerol to 1,3-PDO and synthesize an essential coenzyme B12. In order to connect the glycolytic pathway with the pathway of 1,3-PDO synthesis from glycerol, i.e., to directly produce diol from glucose, glycerol-3-phosphate dehydrogenase and glycerol-3-phosphate phosphatase from Saccharomyces cerevisiae were overexpressed. Additionally, the effect of expression levels and the use of isoforms of these two enzymes on glycerol and 1,3-PDO production were studied...

Nursing and healthcare-associated pneumonia (NHCAP) is a category of healthcare-associated pneumonia that was modified for the healthcare system of Japan. The NHCAP guidelines stated the difficulty in assessing the severity classifications, for instance, A-DROP. We compared the usefulness of different severity classifications (A-DROP, CURB-65, PSI, and I-ROAD) in predicting the prognosis of nursing and healthcare-associated pneumonia. We conducted a retrospective analysis on 303 adult patients hospitalized for nursing healthcare-associated pneumonia and community-acquired pneumonia, which were diagnosed at the Department of Respiratory Medicine of Niigata General City Hospital between January 2012 and December 2014...

OBJECTIVE: Mutations in 23S rRNA gene are known to be associated with macrolide resistance in Mycoplasma pneumoniae (M. pneumoniae). However, these mutations alone do not fully explain the high resistance rates in Asia. The aim of this study was to investigate other possible mutations involved in macrolide resistance in M. pneumoniae. METHODS: The whole genomes of 10 clinical isolates of M. pneumoniae with macrolide resistance were sequenced by Illumina HiSeq2000 platform...

Acute exacerbations and community-acquired pneumonia (CAP) are severe complications in patients with chronic obstructive pulmonary disease (COPD). In this study, we analyzed inflammatory parameters in serum including C-reactive protein (CRP), procalcitonin (PCT), and serum neopterin (NPT) to determine their potential to differentiate between patients with CAP+COPD and with acute exacerbations of COPD (AECOPD) without pneumonia. 102 (39 women and 63 men) patients were included in this retrospective study, of whom 48 presented with CAP without underlying COPD, 20 with CAP+COPD and 34 with AECOPD...

Streptococcus pneumoniae (SP) is a pathogenic bacterium and a major cause of community-acquired pneumonia that could be fatal if left untreated. Therefore, rapid and sensitive detection of SP is crucial to enable targeted treatment during SP infections. In this study, DNA tetrahedron (DNA TH) with a hollow structure is anchored on gold electrodes to construct an electrochemical immunosensor for rapid detection of pneumococcal surface protein A (PspA) peptide and SP lysate from synthetic and actual human samples...

BACKGROUND: Individuals with atopic conditions may have increased susceptibility to infections outside the organs directly affected by their atopic condition. OBJECTIVE: We tested the hypothesis that atopic conditions overall, and stratified by smoking history, are associated with increased risk of hospitalization for infections. METHODS: We collected information on smoking history and self-reported atopic conditions from 105,519 individuals from the general population and followed them for up to 23 years for infectious disease hospitalizations and deaths...

BACKGROUND Adult Still's disease (ASD) is a rare systemic inflammatory condition, which commonly presents with the triad of quotidian fevers, rash, and non-specific rheumatologic symptoms such as myalgia and arthralgia. The etiology and pathogenesis are poorly understood and both the clinical presentation and laboratory data are typically nonspecific. As such, the presentation is often confused with infection, other autoimmune processes, and malignancy. CASE REPORT We present a case of a 29-year-old Hispanic female who presented with fever, sore throat, myalgia, and shortness of breath...
