Validation and clinical application of a nested PCR for paracoccidioidomycosis diagnosis in clinical samples from Colombian patients.
Abstract Paracoccidioidomycosis is a systemic and endemic mycosis, restricted to tropical and subtropical areas of Latin America. The infection is caused by the thermal dimorphic fungus Paracoccidioides brasiliensis and Paracoccidioides lutzii. The diagnosis of paracoccidioidomycosis is usually performed by microscopic examination, culture and immunodiagnostic tests to respiratory specimens, body fluids and/or biopsies; however these methods require laboratory personnel with experience and several days to produce a result. In the present study, we have validated and evaluated a nested PCR assay targeting the gene e...

Home Oxygen Program review: Regionalization in Vancouver Coastal Health and British Columbia.
Abstract Since its inception in the 1980s, the Home Oxygen Program in British Columbia was centrally managed by the Ministry of Health. Initially a small program with few clients across the province, it soon became a large program with many clients and increasing expenditures. A pilot program started in Victoria (British Columbia) in 1996 demonstrated that managing the program locally could offer better client care, better contract management and significant cost savings. In 2002, the pilot's model and recommendations were implemented in British Columbia's five health authorities. The present review details the exp...

Ambient air pollution and lung disease in China: health effects, study design approaches and future research
Abstract Ambient air pollution in China has worsened following dramatic increases in industrialization, automobile use and energy consumption. Particularly bothersome is the increase in the PM2.5 fraction of pollutants. This fraction has been associated with increasing rates of cardio-respiratory disease in China and elsewhere. Ambient pollutant levels have been described in many of China’s cities and are comparable to previous levels in southern California. Lung cancer mortality in China has increased since the 1970s and has been higher in men and in urban areas, the exact explanation for which has not been det...

Whole-heart four-dimensional flow can be acquired with preserved quality without respiratory gating, facilitating clinical use: a head-to-head comparison
Background: Respiratory gating is often used in 4D-flow acquisition to reduce motion artifacts. However, gating increases scan time. The aim of this study was to investigate if respiratory gating can be excluded from 4D flow acquisitions without affecting quantitative intracardiac parameters. Methods: Eight volunteers underwent CMR at 1.5 T with a 5-channel coil (5ch). Imaging included 2D flow measurements and whole-heart 4D flow with and without respiratory gating (Resp(+), Resp(−)). Stroke volume (SV), particle-trace volumes, kinetic energy, and vortex-ring volume were obtained from 4D flow-data. These parameters were...

Elevation of one hour plasma glucose during oral glucose tolerance testing
ConclusionThe risk of CFRD increases with PG1 > 160 mg/dl. No statistically significant evidence of an association between elevated PG1 and pulmonary function was found, yet our results do not exclude the possibility that in males, elevated PG1 may signal adverse changes in FEV1% predicted over time.

Increased autophagy and apoptosis contribute to muscle atrophy in a myotonic dystrophy type 1 Drosophila model [RESEARCH ARTICLE]
ABSTRACT Muscle mass wasting is one of the most debilitating symptoms of myotonic dystrophy type 1 (DM1) disease, ultimately leading to immobility, respiratory defects, dysarthria, dysphagia and death in advanced stages of the disease. In order to study the molecular mechanisms leading to the degenerative loss of adult muscle tissue in DM1, we generated an inducible Drosophila model of expanded CTG trinucleotide repeat toxicity that resembles an adult-onset form of the disease. Heat-shock induced expression of 480 CUG repeats in adult flies resulted in a reduction in the area of the indirect flight muscles. In these model ...

The lung clearance index in young infants: impact of tidal volume and dead space
This study was designed to investigate the effect of lung volumes on LCI in young infants. The dependence of LCI on dead space volume ( V D ), tidal volume ( V T ) and functional residual capacity (FRC) was investigated by mathematical modeling and by MBW measurements using sulfur hexafluoride (SF 6 ) as a tracer gas. MBW was performed in 150 infants, of median postmenstrual age 46.7?weeks, followed up after neonatal intensive care. Wheezing was assessed in 90 of these infants by computerized respiratory sound analysis during quiet sleep. The strongest correlation was observed between LCI and the volume ratios V T /F...

Rapid Detection of Emerging Pathogens and Loss of Microbial Diversity Associated with Severe Lung Disease in Cystic Fibrosis [Bacteriology]
Respiratory infection in cystic fibrosis (CF) is polymicrobial, but standard sputum microbiology does not account for the lung microbiome or detect changes in microbial diversity associated with disease. As a clinically applicable CF microbiome surveillance scheme, total sputum nucleic acids isolated by a standard high-throughput robotic method for accredited viral diagnosis were profiled for bacterial diversity using ribosomal intergenic spacer analysis (RISA) PCR. Conventional culture and RISA were performed on 200 paired sputum samples from 93 CF adults; pyrosequencing of the 16S rRNA gene was applied to 59 patients to ...

Comparative Profile of Heme Acquisition Genes in Disease-Causing and Colonizing Nontypeable Haemophilus influenzae and Haemophilus haemolyticus [Bacteriology]
Nontypeable Haemophilus influenzae (NTHI) are Gram-negative bacteria that colonize the human pharynx and can cause respiratory tract infections, such as acute otitis media (AOM). Since NTHI require iron from their hosts for aerobic growth, the heme acquisition genes may play a significant role in avoiding host nutritional immunity and determining virulence. Therefore, we employed a hybridization-based technique to compare the prevalence of five heme acquisition genes (hxuA, hxuB, hxuC, hemR, and hup) between 514 middle ear strains from children with AOM and 235 throat strains from healthy children. We also investigated the...

Evaluation of Unbiased Next-Generation Sequencing of RNA (RNA-seq) as a Diagnostic Method in Influenza Virus-Positive Respiratory Samples [Virology]
Unbiased nontargeted metagenomic RNA sequencing (UMERS) has the advantage to detect known as well as unknown pathogens and, thus, can significantly improve the detection of viral, bacterial, parasitic, and fungal sequences in public health settings. In particular, conventional diagnostic methods successfully identify the putative pathogenic agent in only 30% to 40% of respiratory specimens from patients with acute respiratory illness. Here, we applied UMERS to 24 diagnostic respiratory specimens (bronchoalveolar lavage [BAL] fluid, sputum samples, and a swab) from patients with seasonal influenza infection and 5 BAL fluid ...

Human metapneumovirus-associated severe acute respiratory illness hospitalisation in HIV-infected and HIV-uninfected South African children and adults
Human metapneumovirus (HMPV) has been implicated as an etiologic agent of lower respiratory tract infection (LRTI) among both healthy and immunocompromised individuals across age groups [1]. The burden of disease is greatest in young children with the majority of infections occurring in children without underlying medical conditions [2,3]. Rates of HMPV infection are lower in adults than children, and severe disease occurs predominantly in the immunocompromised and elderly, who are at increased risk of hospitalisation [4–7].

The use of Next Generation Sequencing in the diagnosis and typing of respiratory infections
Virus specific molecular assays such as real-time PCR (RT-PCR) are now considered the gold standard in the diagnosis of viral respiratory tract infections. They are rapid, relatively inexpensive and offer increased sensitivity and specificity over prior techniques such as virus culture and direct immunofluorescence. Assays can be developed quickly to detect novel / emerging pathogens and can be combined to identify multiple microbiological pathogens in a single test. Yet there is a limit to the number of targets, usually up to four, which can be included in an in-house test before compromising test sensitivity. (Source: Jo...

Pollen-induced Innate Recruitment of Neutrophils Facilitates Induction of Allergic Sensitization and Airway Inflammation.
Abstract Neutrophil recruitment is a hallmark of rapid innate immune responses. Exposure of airways of naïve mice to pollens rapidly induces neutrophil recruitment. The innate mechanisms that regulate pollen-induced neutrophil recruitment, and the contribution of this neutrophilic response to subsequent induction of allergic sensitization and inflammation needs to be elucidated. Here we show that ragweed pollen extract (RWPE)-challenge in naïve mice induces CXCL chemokine synthesis that stimulates CXCR2-dependent recruitment of neutrophils into the airways. Deletion of TLR4 abolishes CXCL chemokine secretion and ...

ApolipoproteinA-1 Overexpression Attenuates Cigarette Smoke Induced Emphysema in Mice.
In this study, the ApoA1 levels were significantly decreased in the lungs of patients with COPD, as well as in the lungs of mice exposed to CS. ApoA1 TG mice did not develop emphysema when chronically exposed to CS. Compared to the control TG mice, ApoA1 overexpression attenuated lung inflammation, oxidative stress, metalloprotease activation, and apoptosis in CS-exposed mouse lungs. To explore a plausible mechanism of anti-apoptotic activity of ApoA1, alveolar epithelial cells (A549) were treated with cigarette smoke extract (CSE).

Chlamydia pneumoniae and Chlamydia Trachomatis Infection Differentially Modulates Human Dendritic Cell Line (MUTZ) Differentiation and Activation
Abstract Chlamydia trachomatis and Chlamydia pneumoniae are important human pathogens that infect the urogenital/anorectal and respiratory tracts, respectively. Whilst the ability of these bacteria to infect epithelia is well defined, there is also considerable evidence of infection of leucocytes, including dendritic cells (DCs). Using a human dendritic cell line (MUTZ), we demonstrate that the infection and replication of chlamydiae inside DCs is species and serovar specific and that live infection with C. pneumoniae is required to upregulate costimulatory markers CD80, CD83 and human leucocyte antigen (HLA)‐DR on MUTZ...
