Achalasia with Megaesophagus and Tracheal Compression in a Young Patient: A Case Report
Conclusion This report emphasizes that physicians should be alert and consider airway obstruction and signs of dyspnea as severe and threatening symptoms in extensive cases of achalasia with megaesophagus. Early surgical treatment provides a therapeutic option to obviate the occurrence of acute respiratory distress and consecutive complications. In particular, difficulties in intubation prior to surgery must be considered. Due to potential tracheomalacia, the status of a “bull frog neck” in achalasia, including severe tracheal compression caused by megaesophagus with concomitant cervical swelling, may also lead to extu...

High risk of delisting or death in liver transplant candidates following infections: Results from the North American consortium for the study of end‐stage liver disease
Because Model for End‐Stage Liver Disease (MELD) scores at the time of liver transplantation (LT) increase nationwide, patients are at an increased risk for delisting by becoming too sick or dying while awaiting transplantation. We quantified the risk and defined the predictors of delisting or death in patients with cirrhosis hospitalized with an infection. North American Consortium for the Study of End‐Stage Liver Disease (NACSELD) is a 15‐center consortium of tertiary‐care hepatology centers that prospectively enroll and collect data on infected patients with cirrhosis. Of the 413 patients evaluated, 136 were lis...

Molecular epidemiological analysis of Saffold cardiovirus genotype 3 from upper respiratory infection patients in Taiwan
Saffold cardiovirus (SAFV) belongs to the Cardiovirus genus of Picornaviridae family, which includes other pathogenic viruses involved in human hand, foot and mouth diseases (HFMD) such as enteroviruses [1,2]. The Cardiovirus genus includes two species: Theilovirus and Encephalomyocarditis virus. A newly identified Theilovirus named SAFV has been isolated from an 8-month-old child with fever of unknown origin in 2007 and designated as SAFV genotype 1 (SAFV-1) [1,3]. SAFV is distinct from Theiler’s murine encephalomyelitis virus (TMEV), Vilyuisk human encephyalomyelitis virus (VHEV) and Theiler-like rat virus (TRV) making...

Markers for upper limb dysfunction in Amyotrophic Lateral Sclerosis using analysis of typing activity
Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disorder involving upper and lower limb function, as well as bulbar and respiratory muscles (Andersen et al., 2012; Miller et al., 2013). Most ALS patients (85 to 90%) need assistive devices at some stage during disease progression, to assist in communication and social interaction (Beukelman et al., 2011; Brownlee and Bruening, 2012). Depending on disease stage, different interface technologies are required to enhance autonomy. (Source: Clinical Neurophysiology)

The Effect of Body Mass Index on Post-Vaccination Maternal and Neonatal Pertussis Antibody Levels
The bacterium, Bordatella pertussis, is responsible for pertussis, a highly contagious respiratory infection which most commonly affects young children. Pertussis is particularly dangerous to infants under one year of age who may present with periods of potentially fatal apnea (Cortese et al, 2008). The Centers for Disease Control (CDC) reported 48,277 cases of pertussis in 2012 in the United States, the highest reported number of cases since 1955 (CDC, 2012). Infants cannot be vaccinated against pertussis until approximately two months of age and are thus susceptible to pertussis during this time period. (Source: Journal ...

Junctional abnormalities in human airway epithelial cells expressing delF508 CFTR.
We examined changes to CFTR function, tight junctions, and gap junctions in NuLi-1 (CFTRwt/wt) and CuFi-5 (CFTRΔF508/ΔF508). Cells were studied at air-liquid interface (ALI) and compared to primary human bronchial epithelial cells. Based on fluorescent lectin binding, the phenotype of the NuLi-1 and CuFi-5 at week 8 resembled serous, glycoprotein-rich airway cells. After 7 weeks at ALI, CuFi-5 cells possessed 130% of the ENaC activity and 17% of the CFTR activity found in NuLi-1. In both cell types, expression levels of CFTR were comparable to CFTR levels found in primary airway epithelia. Transepithelial resistance (TER...

Phenotype of Normal Spirometry in an Aging Population.
CONCLUSION: GLI-defined normal spirometry, even when classified as respiratory impairment by GOLD, included adjusted mean values in the normal range for multiple phenotypes. These results suggest that among adults with GLI-defined normal spirometry, GOLD may misclassify normal phenotypes as having respiratory impairment.

The bacterial microbiota in inflammatory lung diseases.
Abstract Numerous lines of evidence, ranging from recent studies back to those in the 1920's, have demonstrated that the lungs are NOT bacteria-free during health. We have recently proposed that the entire respiratory tract should be considered a single ecosystem extending from the nasal and oral cavities to the alveoli, which includes gradients and niches that modulate microbiome dispersion, retention, survival and proliferation. Bacterial exposure and colonization of the lungs during health is most likely constant and transient, respectively. Host microanatomy, cell biology and innate defenses are altered during ...

Impacts of Particulate Air Pollution on Asthma: Current Understanding and Future Perspectives.
Authors: Takizawa H Abstract The impacts of air pollution on human health and disease have been attracting attention, especially in industrialized countries and areas with heavy traffic burdens. Fine particulate matters (PMs) are considered as an important air pollutant, since it was reported that there was a significant relationship between PM2.5 levels and mortality by cohort studies in 1990s. Epidemiological and toxicological studies have strongly suggested a causative relationship between fine particulate air pollution and increased incidence as well as exacerbations of asthma, and other respiratory disorders. ...

Prevalence of respiratory virus in symptomatic children in private physician office settings in five communities of the state of Veracruz, Mexico
Conclusions: A large proportion of respiratory infections in the community setting in Mexico was associated to viruses. Although testing for common respiratory pathogens in children with acute respiratory tract infections may lead to a better understanding of the role of viral pathogens in, and eventually to improvement in the management of, individual patients, additional prospective studies are required to study the need of routinely using such tests in general pediatric practices in resource-limited countries.

Tuberculosis: A disease without boundaries
Tuberculosis (TB) is an airborne disease caused by Mycobacterium tuberculosis (MTB) that usually affects the lungs leading to severe coughing, fever, and chest pains. Although current research in the past four years has provided valuable insight into TB transmission, diagnosis, and treatment, much remains to be discovered to effectively decrease the incidence of and eventually eradicate TB. The disease still puts a strain on public health, being only second to HIV/AIDS in causing high mortality rates. (Source: Tuberculosis)

Pi Effects on Mitochondrial Ca2+ [Metabolism]
The large inner membrane electrochemical driving force and restricted volume of the matrix confer unique constraints on mitochondrial ion transport. Cation uptake along with anion and water movement induces swelling if not compensated by other processes. For mitochondrial Ca2+ uptake, these include activation of countertransporters (Na+/Ca2+ exchanger and Na+/H+ exchanger) coupled to the proton gradient, ultimately maintained by the proton pumps of the respiratory chain, and Ca2+ binding to matrix buffers. Inorganic phosphate (Pi) is known to affect both the Ca2+ uptake rate and the buffering reaction, but the role of anio...

Differential regulation of metabolic parameters by energy deficit and hunger
: Hypocaloric diet decreases both energy expenditure (EE) and respiratory exchange rate (RER), affecting the efficacy of dieting inversely. Energy deficit and hunger may be modulated separately both in human and animal studies by drug treatment or food restriction.
