Chemical characterization and in vitro toxicity of diesel exhaust particulate matter generated under varying conditions
Abstract Epidemiologic studies have linked diesel exhaust (DE) to cardiovascular and respiratory morbidity and mortality, as well as lung cancer. DE composition is known to vary with many factors, although it is unclear how this influences toxicity. We generated eight DE atmospheres by applying a 2 × 2 × 2 factorial design and altering three parameters in a controlled exposure facility: (1) engine load (27 vs 82 %), (2) particle aging (residence time ~5 s vs ~5 min prior to particle collection), and (3) oxidation (with or without ozonation during dilution). Selected exposure concentrations of both die...

Unique properties of cbb3 H+ channel [Biophysics and Computational Biology]
The respiratory chains of nearly all aerobic organisms are terminated by proton-pumping heme-copper oxygen reductases (HCOs). Previous studies have established that C-family HCOs contain a single channel for uptake from the bacterial cytoplasm of all chemical and pumped protons, and that the entrance of the KC-channel is a conserved glutamate...

Shear stress upregulates IL‐1β secretion by Chlamydia pneumoniae‐ infected monocytes
Abstract Infectious agents are increasingly implicated in the development and progression of chronic inflammatory diseases. Several lines of evidence suggest that the common intracellular respiratory pathogen, Chlamydia pneumoniae contributes to the well‐established risk factors of atherosclerosis but the exact mechanism is not well understood. It is believed that C. pneumoniae‐infected monocytes travel from the lung to the atherosclerotic foci, during which the cells experience mechanical stimuli due to blood flow. In this work, we characterized the effect of physiological levels of shear stress on C. pneumoniae‐inf...

Lung squamous carcinoma with two paraneoplastic syndromes ‐Dermatomyositis and Lambert‐Eaton myasthenic syndrome
We reported a case of a 60‐year‐old male smoker who presented multiple erythematous lesion for six months with progressive proximal muscular weakness, and developed to dysphonia in two months. His chest computed tomography showed a spiculate pulmonary nodule near the hilar in the right upper lobe and mediastinal lymph nodes enlargement. Lung biopsy showed squamous cell carcinoma. The patients’blood test revealed elevated creatine kinase levels. Electromyography results was consistent with moderate myopathy accompanied with a pattern suggestive of Lambert‐Eaton myasthenic syndrome. So we made the diagnosis of an ove...

Tuberculous pleuritis secondary to Mycobacterium bovis in a veterinarian
Abstract Mycobacterium bovis is a rare cause of tuberculosis in humans, but should be considered in individuals at risk secondary to medical co‐morbidities (notably immunocompromise) or occupational exposure. Most cases are secondary to re‐activation of latent infection in elderly individuals although cases of primary infection still occur, usually involving animal‐to‐human transmission. Pleural fluid culture in the context of suspected tuberculous pleuritis is frequently negative and pleural biopsy significantly increases the likelihood of confirming the diagnosis histologically and microbiologically. Although tho...

The present and future of tuberculosis vaccinations
The clinical, social, and economic burden of tuberculosis (TB) remains high worldwide, thereby highlighting the importance of TB prevention. The bacilli Calmette-Guérin (BCG) vaccine that is currently available can protect younger children but is less effective in adults, the major source of TB transmission. In addition, the emergence of drug-resistant Mycobacterium tuberculosis (Mtb) strains and the high prevalence of HIV infection have significantly complicated TB prognosis and treatment. Together, these data highlight the need for new and more effective vaccines. (Source: Tuberculosis)

Pilot Randomised Controlled Trial to Test Effectiveness of Facemasks in Preventing Influenza-Like Illness Transmission Among Australian Hajj Pilgrims in 2011.
Abstract Studies to determine the effectiveness of facemasks in preventing influenza have been inconclusive, largely due to small sample size. The Hajj pilgrimage, where the incidence of influenza and other respiratory infections is high, provides an excellent opportunity to test the effectiveness of facemasks against syndromic and laboratory-confirmed infections. Hence, a pilot study was conducted among Australian pilgrims to assess the feasibility of such a large-scale trial in the coming years. At the 2011 Hajj, tents were randomised to 'supervised mask use' versus 'no supervised mask use'. Pilgrims with ILI sym...

Oxidative stress, cardiolipin and mitochondrial dysfunction in nonalcoholic fatty liver disease.
Abstract Nonalcoholic fatty liver disease (NAFLD) is today considered the most common form of chronic liver disease, affecting a high proportion of the population worldwide. NAFLD encompasses a large spectrum of liver damage, ranging from simple steatosis to steatohepatitis, advanced fibrosis and cirrhosis. Obesity, hyperglycemia, type 2 diabetes and hypertriglyceridemia are the most important risk factors. The pathogenesis of NAFLD and its progression to fibrosis and chronic liver disease is still unknown. Accumulating evidence indicates that mitochondrial dysfunction plays a key role in the physiopathology of NAF...

Interventions for managing asthma in pregnancy.
CONCLUSIONS: Based on eight included trials, of moderate quality overall, no firm conclusions about optimal interventions for managing asthma in pregnancy can be made. Five trials assessing pharmacological interventions did not provide clear evidence of benefits or harms to support or refute current practice. While inhaled magnesium sulphate for acute asthma was shown to reduce exacerbations, this was in one small trial of unclear quality, and thus this finding should be interpreted with caution. Three trials assessing non-pharmacological interventions provided some support for the use of such strategies, however were not ...

Respiratory Mechanics in Mechanically Ventilated Patients.
Abstract Respiratory mechanics refers to the expression of lung function through measures of pressure and flow. From these measurements, a variety of derived indices can be determined, such as volume, compliance, resistance, and work of breathing. Plateau pressure is a measure of end-inspiratory distending pressure. It has become increasingly appreciated that end-inspiratory transpulmonary pressure (stress) might be a better indicator of the potential for lung injury than plateau pressure alone. This has resulted in a resurgence of interest in the use of esophageal manometry in mechanically ventilated patients. End...

Ventilator Liberation for High-Risk-for-Failure Patients: Improving Value of the Spontaneous Breathing Trial.
Abstract Several patient populations have been identified as high risk for extubation failure despite successful completion of a spontaneous breathing trial (SBT). Extubation failure and subsequent need for emergent re-intubation have been associated with increased morbidity and mortality. In this review, we discuss ways to optimize the value and performance of the SBT in a subgroup of high-risk patients (elderly, cardiac, and/or respiratory failure) to reduce the rate of extubation failure. We recommend the use of T-piece mode, longer duration SBT, and measurement of the rapid shallow breathing index (breathing fr...

A Case of Lung Cancer Originating from Cavitary Mycobacterium xenopi Infection.
Abstract Coexistence of Mycobacterium xenopi with lung cancer has been reported. However, lung cancer originating within a pre-existing cavity caused by M. xenopi has not. A 55-y-old woman with a history of smoking presented with complaints of chronic dry cough, night sweats, and weight loss for several months. Computed tomography (CT) scanning revealed a 3.5-cm irregular thick-walled cavity in the right lung apex. Cultures obtained from a CT-guided biopsy grew M. xenopi. The patient received standard treatment, and her clinical symptoms improved, and the radiographic lesion stabilized. However, 2 y later, a repeat...
