Respiratory Syncytial Virus-Associated Hospitalizations in Pre-Mature Infants in Lima, Peru.
Abstract We conducted a prospective cohort study in four hospitals in Lima, Peru in infants with a birth weight ≤ 1,500 g followed from birth hospital discharge up to 1 year of age to determine the incidence of respiratory syncytial virus (RSV) hospitalizations. We enrolled 222 infants from March of 2009 to March of 2010 infants: 48 infants with a birth weight < 1,000 g and 174 infants with a birth weight of 1,000-1,500 g (birth weight = 1,197 ± 224 g; gestational age = 30.1 ± 2.6 weeks). There were 936 episodes of respiratory infections; the incidence of respiratory infections during the first 1 year of lif...

Pulmonary rehabilitation for interstitial lung disease.
CONCLUSIONS: Pulmonary rehabilitation seems to be safe for people with ILD. Improvements in functional exercise capacity, dyspnoea and quality of life are seen immediately following pulmonary rehabilitation, with benefits also evident in IPF. Because of inadequate reporting of methods and small numbers of included participants, the quality of evidence was low to moderate. Little evidence was available regarding longer-term effects of pulmonary rehabilitation. PMID: 25284270 [PubMed - as supplied by publisher] (Source: Cochrane Database of Systematic Reviews)

Characteristics of candidates for lung transplantation due to chronic obstructive pulmonary disease and alpha-1 antitrypsin deficiency emphysema.
CONCLUSIONS: The number of patients receiving a lung transplant for COPD has progressively increased and the tendency is to perform the evaluation in earlier stages of the disease. Patients receiving transplants for COPD and AATD had similar characteristics at the time of the evaluation, although AATD patients were younger and had less exposure to tobacco and lower PCO2.

strains spreading in Hanoi, Vietnam: Beijing sublineages, genotypes, drug susceptibility patterns, and host factors
Beijing genotype strains are divided into two major sublineages, ancient (atypical) and modern (typical) types, but their phenotypic variations remain largely unknown. Mycobacterium tuberculosis (MTB) isolates from Hanoi, Vietnam, were analyzed by single-nucleotide polymorphisms and spoligotyping. Patient information and drug susceptibility patterns were obtained. Genetic clustering was assessed by variable number of tandem repeat (VNTR) locus sets. Multivariate analysis was also performed to investigate factors possibly associated with these sublineages.

Serum and bal beta--glucan for the diagnosis of pneumonia in HIV positive patients
The diagnosis of patients with pulmonary infiltrates and human immunodeficiency virus (HIV) infection remains a challenge. In current clinical practice the gold standard for Pneumocystis jirovecii pneumonia (PCP) diagnosis remains the identification of the organism in bronco alveolar lavage (BAL) using microscopy (e.g., silver stain). (1->3)-β -d-glucan (BG) is a polysaccharide that is present within the cell wall of Pneumocystis and other fungi. (Source: Respiratory Medicine CME)

Conclusions: Candidate proteins and miRNAs associated with the general diagnosis of dyspnea have been identified in subjects with differing medical diagnoses. Since these markers can be measured in readily obtained clinical samples, further studies are possible that test the value of these findings in more formal classification or case-control studies in much larger cohorts of subjects with specific lung diseases such as asthma, emphysema, or some other well-defined lung disease.

Anticholinergics/Antimuscarinic Drugs in Asthma
Abstract Anticholinergic alkaloids have been used for thousands of years for the relief of bronchoconstriction and other respiratory symptoms, and their use in the treatment of chronic obstructive pulmonary disease is well established. Acetylcholine, acting through muscarinic receptor (M) receptor, modulates multiple physiologic functions pertinent to asthma including airway muscle tone, mucus gland secretion, and various parameters of inflammation and remodeling. In addition, activation of M receptors may inhibit beta2 adrenoreceptor. These observations offer the rationale for the use of M receptors antagonists ...

Intestinal current measurement versus nasal potential difference measurements for diagnosis of cystic fibrosis: a case-control study
Background: Nasal potential difference (NPD) and intestinal current measurement (ICM) are functional CFTR tests that are used as adjunctive diagnostic tools for cystic fibrosis (CF). Smoking has a systemic negative impact on CFTR function. A diagnostic comparison between NPD and ICM and the impact of smoking on both CFTR tests has not been done. Methods: The sweat chloride test, NPD, and ICM were performed in 18 patients with CF (sweat chloride >60 mmol/l), including 6 pancreatic sufficient (PS) patients, and 13 healthy controls, including 8 smokers. The NPD CFTR response to Cl-free and isoproterenol perfusion (Delta0Cl- +...

Systematic identification of transcriptional and post-transcriptional regulations in human respiratory epithelial cells during influenza A virus infection
Conclusion: Compared with other representative state-of-the-art algorithms, the proposed SITPR framework can more effectively identify the activated transcriptional and post-transcriptional regulations simultaneously from a given background network. The idea of SITPR is generally applicable to the analysis of gene regulatory networks in human cells. The results obtained for human respiratory epithelial cells suggest the importance of the transcriptional, post-transcriptional regulations as well as their synergies in the innate immune responses against IAV infection.

A chalcone with potent inhibiting activity against biofilm formation by nontypeable Haemophilus influenzae
In this study, a series of natural and synthetic chalcones with various chemical substituents were evaluated in vitro for their antibiofilm activities against strong biofilm‐forming strains of NTHi. Of the test chalcones, 3‐hydroxychalcone (chalcone 8) exhibited the most potent inhibitory activity, its mean minimum biofilm inhibitory concentration (MBIC50) being 16 μg/mL (71.35 μM), or approximately sixfold more active than the reference drug, azithromycin (MBIC50 419.68 μM). The inhibitory activity of chalcone 8, which is a chemically modified chalcone, appeared to be superior to those of the natural chalcone...

Duration of Gestation and Mode of Delivery Affect the Genes of Transepithelial Sodium Transport in Pulmonary Adaptation.
Conclusions: In late preterm and early term infants, low expression of ENaC and SGK1 may parallel insufficient lung liquid clearance predisposing to respiratory distress. Lower SGK1 expression after term CD could translate into insufficient sodium and lung liquid absorption. The findings demonstrate a central role for cortisol in regulation of ENaC and potentially perinatal sodium and lung liquid clearance. © 2014 S. Karger AG, Basel.

Snoring – Obnoxious (but medically innocent) noise or wakeup call for sleep medicine?
In the present issue of Sleep Medicine Reviews, there are two articles with complementary reviews of adult and pediatric snoring [1,2]. Both studies acknowledge that snoring is often a marker of obstructive sleep apnea, but they also highlight the greater frequency of this symptom and its potential independent clinical importance. The most important issue raised by both reviews is the persisting question about the significance of snoring in the absence of frank obstructive sleep apnea. Both reviews allude to the assumption that snoring is the mildest form of the obstruction we loosely call “sleep disordered breathing” ...

Bioenergetic differences between MCF-7 and T47D breast cancer cells and their regulation by estradiol and tamoxifen
Estrogen receptor α (ERα+) breast tumors rely on mitochondria (mt) to generate ATP. The goal of this study was to determine how estradiol (E2) and 4-hydroxytamoxifen (4-OHT) affect cellular bioenergetic function in MCF-7 and T47D ERα+ breast cancer cells in serum-replete versus dextran-coated charcoal (DCC)-stripped fetal bovine serum (FBS)-containing medium (‘serum-starved’). Serum-starvation reduced oxygen consumption rate (OCR), extracellular acidification rate (ECAR), ATP-linked OCR, and maximum mt capacity, reflecting lower ATP demand and mt respiration.

Thromboxane-Induced Actin Polymerization in Hypoxic Neonatal Pulmonary Arterial Myocytes Involves Cdc42 Signaling.
Abstract In hypoxic pulmonary arterial (PA) myocytes, challenge with thromboxane mimetic U46619 induces marked actin polymerization and contraction, phenotypic features of persistent pulmonary hypertension of the newborn (PPHN). Rho GTPases regulate the actin cytoskeleton. We previously reported U46619-induced actin polymerization in hypoxic PA myocytes occurs independently of the RhoA pathway, and hypothesized involvement of the Cdc42 pathway. PA myocytes grown in normoxia or hypoxia for 72 hrs were stimulated with U46619, then analyzed for Rac/Cdc42 activation by affinity precipitation, PI3K activity by phospho-A...

Animal models of bronchopulmonary dysplasia. V: The preterm baboon models.
Abstract Much of the progress in improved neonatal care, particularly management of under-developed preterm lungs, has been aided by investigations of multiple animal models, including the neonatal baboon (Papio species). In this chapter we highlight how the preterm baboon model at both140d and 125 d gestation (term equivalent 185d) has advanced our understanding and management of the immature human infant with neonatal lung disease. Not only is the 125-d baboon model extremely relevant to the condition of BPD but there are also critical neurodevelopmental and other end-organ pathological features associated with t...

Carl Wilhelm Scheele, the discoverer of oxygen, and a very productive chemist.
Abstract Carl Wilhelm Scheele (1742-1786) has an important place in the history of the discovery of respiratory gases because he was undoubtedly the first person to prepare oxygen and describe some of its properties. In spite of this, his contributions have often been overshadowed by those of Joseph Priestley and Antoine Lavoisier who also played critical roles in preparing the gas and understanding its nature. Sadly, Scheele was slow to publish his discovery and therefore Priestley is rightly recognized as the first person to report the preparation of oxygen. Having said this, the thinking of both Scheele and Prie...
