Classifying patients by their characteristics and clinical presentations; the use of latent class analysis
Abstract In this article, we introduce the general statistical analysis approach known as latent class analysis and discuss some of the issues associated with this type of analysis in practice. Two recent examples from the respiratory health literature are used to highlight the types of research questions that have been addressed using this approach. (Source: Respirology)

The pathogenesis of pneumothorax in Birt–Hogg–Dubé syndrome: A hypothesis
The development and natural course of lung cysts in patients with Birt–Hogg–Dubé syndrome (BHD) is still unclear, and the relationship between lung cysts and pneumothorax is not fully clarified. Based on the follow‐up results of thoracic imaging in six patients with BHD, we hypothesize that decreased potential for stretching of the cysts' wall and extensive contact with the visceral pleura are probably responsible for rupture of the cyst wall resulting in increased risk for pneumothorax.

Glycomic Profiles of Ferret Respiratory Tissues [Glycobiology and Extracellular Matrices]
The initial recognition between influenza virus and the host cell is mediated by interactions between the viral surface protein hemagglutinin and sialic acid-terminated glycoconjugates on the host cell surface. The sialic acid residues can be linked to the adjacent monosaccharide by α2–3- or α2–6-type glycosidic bonds. It is this linkage difference that primarily defines the species barrier of the influenza virus infection with α2–3 binding being associated with avian influenza viruses and α2–6 binding being associated with human strains. The ferret has been extensively used as an animal model to study the tran...

Antibiotics for bronchiolitis in children under two years of age.
CONCLUSIONS: This review did not find sufficient evidence to support the use of antibiotics for bronchiolitis, although research may be justified to identify a subgroup of patients who may benefit from antibiotics. Further research may be better focused on determining the reasons that clinicians use antibiotics so readily for bronchiolitis, how to reduce their use and how to reduce clinician anxiety about not using antibiotics.

Antibiotics for community-acquired pneumonia in adult outpatients.
CONCLUSIONS: Available evidence from recent RCTs is insufficient to make new evidence-based recommendations for the choice of antibiotic to be used for the treatment of CAP in outpatient settings. Pooling of study data was limited by the very low number of studies assessing the same antibiotic pairs. Individual study results do not reveal significant differences in efficacy between various antibiotics and antibiotic groups. However, two studies did find significantly more adverse events with use of cethromycin as compared to clarithromycin and nemonoxacin when compared to levofloxacin. Multi-drug comparisons using similar ...

Organic Changes in the Central Nervous System in Children on Chronic Inhaled Corticosteroid Therapy.
In conclusion, patients receiving chronic inhaled corticosteroids had small subcortical hyperintense foci and features of mild supratentorial cortical atrophy. These findings suggest that ICS exposure may be associated with the development of organic changes in CNS. Further studies are needed to detail the extent of brain ICS-induced changes in children on chronic inhalative corticosteroid therapy as well as delayed impact of these changes on psychomotor functioning in adulthood.

ECMO support for right main bronchial disruption in multiple trauma patient with brain injury-a case report and literature review.
Abstract Extracorporeal membrane oxygenation (ECMO) may offer life-saving treatment in severe pulmonary contusion or acute respiratory distress syndrome when conventional treatments have failed. However, because of the bleeding risk of systemic anticoagulation, ECMO should be performed only as a last resort in multiple trauma victims. Here, we report ECMO as a bridge for right main bronchus reconstruction and recovery of traumatic wet lung in a 31-year-old male multi-trauma patient with right main bronchial disruption, bilateral pulmonary contusion, cerebral contusion and long bone fracture. The patient was dischar...

Current concept of transcatheter closure of atrial septal defect in adults.
Abstract After the introduction of catheter intervention for atrial septal defect (ASD) in the pediatric population, therapeutic advantages of this less invasive procedure were focused on adult through geriatric populations. The most valuable clinical benefits of this procedure are the significant improvement of symptoms and daily activities, which result from the closure of left to right shunt without thoracotomy and cardiopulmonary bypass surgery. These benefits contribute to increase the number of adult patients of this condition who have hesitated over surgical closure. In terms of technical point of view for c...

Frequency of viral etiology in symptomatic adult upper respiratory tract infections.
CONCLUSION: Results presented in this report suggest that respiratory viral infections are largely under diagnosed in immunocompetent adults. Although the majority of young adult infections are not life-threatening they may impose a significant burden, especially in developing countries since these individuals represent a large fraction of the working force.

CT findings of probable UIP have a high predictive value for histologic UIP.
Conclusions:Probable CT UIP is associated with a higher rate of histologic UIP than indeterminate CT UIP suggesting that they are distinct groups and should not be combined into a single CT category as currently recommended by guidelines. CT and microscopic honeycombing may be dissimilar entities. The T allele at rs35705950 predicts a UIP diagnosis by both chest CT and histology. Background: The current UIP/IPF CT classification system excludes probable UIP as a diagnostic category. We sought to determine the predictive effect of probable CT UIP on histology, and to determine the effect of the promoter polymorphism in ...

Non-Invasive Positive Pressure Ventilation Following Esophagectomy: Safety Demonstrated in a Pig Model.
Conclusions:Our pig model suggests that an esophagectomy anastomosis can tolerate a considerably higher pressure than is transmitted to the esophagus during NPPV. NPPV may be a safe alternative to ET after esophagectomy. Background: Respiratory complications occur in 20-65% of esophagectomy patients. While non-invasive positive pressure ventilation (NPPV) is associated with fewer complications than endotracheal intubation (ET), it is relatively contraindicated after esophagectomy due to potential injury to the anastomosis. We created an ex vivo and in vivo pig model to determine the pressure tolerance of an esophagecto...

Pre-Intubation application of oral chlorhexidine does not provide additional benefit in prevention of early onset ventilator-associated pneumonia.
ConclusionsAlthough it is feasible to deliver CHX prior to intubation (including emergent or urgent intubation), the results suggest that pre-intubation CHX may be inconsequential when the ventilator bundle, including daily oral CHX, is in place. During the pre-intubation period, providers should focus their attention on other critical activities.Clinical Trial Registration:ClinicalTrials.gov NCT00893763. Introduction: Daily application of oral chlorhexidine gluconate (CHX) following intubation to reduce risk of ventilator-associated pneumonia (VAP) is now standard of care in many intensive care units.

Prognostic Accuracy of Clinical Prediction Rules for Early Post-Pulmonary Embolism All-Cause Mortality: A Bivariate Meta-Analysis.
Conclusions:Numerous CPRs for prognosticating early mortality in aPE patients are available, but not all demonstrate the high sensitivity needed to reassure clinicians. Background: Studies suggest outpatient treatment or early discharge of acute pulmonary embolism (aPE) is reasonable for those deemed to be at low-risk of early mortality. We sought to determine clinical prediction rule (CPR) accuracy for identifying aPE patients at low-risk for mortality. Methods: We performed a literature search of Medline and Embase from January 2000-March 2014, along with a manual search of references. We included studies derivin...

Bardet Biedl Syndrome: Motile Ciliary Phenotype.
In conclusion motile ciliary structure and function is essentially normal in patients with BBS. Cilia line the surface of the respiratory tract and beat in a coordinated wave to protect the lungs against infection. Bardet Biedl Syndrome (BBS) is rare condition attributed to cilia dysfunction. Murine models of BBS suggest a respiratory phenotype, however, no reports have studied the translation of these findings in patients. We assessed clinical symptoms of motile cilia dysfunction and histology of ciliated respiratory epithelium in patients with BBS. We report an increased prevalence of neonatal respiratory dis...

Choosing Wisely in Critical Care Maximizing Value in the Intensive Care Unit.
Abstract Abstract: Overuse of medical tests and treatments wastes health care resources and leads to unnecessary complications, while underuse results in delayed or missed diagnoses and treatment opportunities. Such problems are well recognized and there have been multiple attempts to correct inappropriate diagnostic testing and treatment over the past several decades. However, sustainable solutions have proven to be elusive. PMID: 25317583 [PubMed - as supplied by publisher] (Source: Chest)

Childhood consequences of maternal obesity and excessive weight gain during pregnancy
Abstract Obesity is a major public health concern. In western countries, the prevalence of obesity in pregnant women has strongly increased, with reported prevalence rates reaching 30%. Also, up to 40% of women gain an excessive amount of weight during pregnancy. Recent observational studies and meta‐analyses strongly suggest long‐term impact of maternal obesity and excessive weight gain during pregnancy on adiposity, cardiovascular and respiratory related health outcomes in their children. These observations suggest that maternal adiposity during pregnancy may program common health problems in the offspring. Currently...

Trichomonas vaginalis Induces Cytopathic Effect on Human Lung Alveolar Basal Carcinoma Epithelial Cell Line A549.
Abstract Trichomonas vaginalis, the causative agent of trichomoniasis is generally known to inhabit the genitourinary tract. However, several case reports with supporting molecular and immunological identifications have documented its occurrence in the respiratory tract of neonates and adults. In addition, the reports have documented that its occurrence is associated with respiratory failures. The medical significance or consequence of this association is unclear. Thus, to establish the possible outcome from the interaction of T. vaginalis with lung cells, the cytopathic effects of the parasites were evaluated usin...

Whole genome response in guinea pigs infected with the high virulence strain TT372
In this study we conducted a microarray-based whole genomic analysis of gene expression in the lungs after exposure of guinea pigs to a low dose aerosol of the Atypical Beijing Western Cape TT372 strain of Mycobacterium tuberculosis, after harvesting lung tissues three weeks after infection at a time that effector immunity is starting to peak. The infection resulted in a very large up-regulation of multiple genes at this time, particularly in the context of a “chemokine storm” in the lungs. Overall gene expression was considerably reduced in animals that had been vaccinated with BCG two months earlier, but in both case...

Is infection with hypermutable clinically significant?
Hypermutable Pseudomonas aeruginosa (HPA) with high mutation rate due to defects in the DNA mismatch repair genes are frequently isolated in the sputum of cystic fibrosis (CF) patients. These isolates tend to be multidrug resistant and may be better adapted to the CF lung environment. However, the clinical significance of this infection has not been determined.

Accuracy of pulmonary auscultation to detect abnormal respiratory mechanics: A cross-sectional diagnostic study
Pulmonary auscultation is a method used in clinical practice for the evaluation and detection of abnormalities relating to the respiratory system. This method has limitations, as it depends on the experience and hearing acuity of the examiner to determine adventitious sounds. In this context, it’s important to analyze whether there is a correlation between auscultation of lung sounds and the behavior of the respiratory mechanical properties of the respiratory system in patients with immediate postoperative cardiac surgery.

Pathogenesis of Middle East respiratory syndrome coronavirus
This article reviews the clinical and pathological available on MERS and compares it to SARS. Most importantly, chest radiographs and imaging results of patients with MERS show features that resemble the findings of organizing pneumonia, different from the lesions in SARS patients, which show fibrocellular intra‐alveolar organization with a bronchiolitis obliterans organizing pneumonia‐like pattern. These findings are in line with differences in the induction of cytopathological changes, induction of host gene responses and sensitivity to the antiviral effect of interferons in vitro when comparing both MERS‐CoV and S...

Exchange transfusion can be life-saving in severe propanil poisoning: a case report
Conclusion: Propanil has potential to produce severe life threatening clinical manifestations, despite categorization as a herbicide with low toxicity. In cases of severe poisoning, exchange transfusion may be life saving. Since methylene blue, intensive care and exchange transfusion facilities are also not readily available in local hospitals, which frequently encounter cases of severe Propanil poisoning, early transfer of patients to tertiary care hospitals should be considered. Exchange transfusion may be helpful even in late stages in patients with severe poisoning. (Source: BMC Research Notes)

Inhibitors of PDE4, but Not PDE3, Increase β2-agonist-induced Expression of Anti-inflammatory MKP-1 in Airway Smooth Muscle Cells.
Abstract β2-agonists are principally used in asthma to provide bronchodilation, however they also have anti-inflammatory properties due, in part, to their ability to upregulate mitogen-activated protein kinase phosphatase 1 (MKP-1) in a cAMP-dependent manner. Phosphodiesterases (PDEs) are attractive targets for potentiating the anti-inflammatory response. There are 11 subfamilies of PDE enzymes, among these, inhibition of PDE3 and PDE4 are the main targets for airway smooth muscle (ASM). PDE enzymes are important intracellular regulators that catalyze the breakdown of cAMP and/or cGMP to their inactive forms. Give...

Regulatory T Cell DNA Methyltransferase Inhibition Accelerates Resolution of Lung Inflammation.
Abstract Acute respiratory distress syndrome (ARDS) is a common and oftentimes fatal inflammatory lung condition without effective targeted therapies. Regulatory T cells (Tregs) resolve lung inflammation, but mechanisms that enhance Tregs to promote resolution of established damage remain unknown. DNA demethylation at the forkhead box protein 3 (Foxp3) locus and other key Treg loci typify the Treg lineage. To test how dynamic DNA demethylation affects lung injury resolution, we administered the DNA methyltransferase inhibitor 5-aza-2'-deoxycytidine (DAC) to wild type mice beginning 24 hours after intratracheal lipo...

The thermic effect of sugar-free Red Bull: Do the non-caffeine bioactive ingredients in energy drinks play a role?
CONCLUSIONS: sfRB enhanced thermogenesis and marginally shifted RQ to favor carbohydrate oxidation. The stimulatory effects of sfRB on REE are mimicked by water + caffeine, indicating that the auxiliary ingredients do not influence this thermic effect. The metabolic effects of sfRB are primarily due to caffeine alone. PMID: 25294090 [PubMed - as supplied by publisher] (Source: Obesity)
