A Bayesian localized conditional autoregressive model for estimating the health effects of air pollution
Summary Estimation of the long‐term health effects of air pollution is a challenging task, especially when modeling spatial small‐area disease incidence data in an ecological study design. The challenge comes from the unobserved underlying spatial autocorrelation structure in these data, which is accounted for using random effects modeled by a globally smooth conditional autoregressive model. These smooth random effects confound the effects of air pollution, which are also globally smooth. To avoid this collinearity a Bayesian localized conditional autoregressive model is developed for the random effects. This localize...

Stroke Alters Respiratory Burst in Neutrophils and Monocytes [Clinical Sciences]
Conclusions— Stroke-induced immune alterations include impairment of the first-line defense performed by specialized phagocytes against bacteria. The hypothesis that these changes enhance susceptibility to acquired infections is supported by our observation that on admission oxidative burst in monocytes was more impaired in patients with stroke with subsequent stroke-associated infections.

A practical approach to the theoretical models to calculate NO parameters of the respiratory system
Expired nitric oxide (NO) is used as a biomarker in different respiratory diseases. The recommended flow rate of 50 mL s −1 (F E NO 0.05 ) does not reveal from where in the lung NO production originated. Theoretical models of NO transfer from the respiratory system, linear or nonlinear approaches, have therefore been developed and applied. These models can estimate NO from distal lung (alveolar NO) and airways (bronchial flux). The aim of this study was to show the limitation in exhaled flow rate for the theoretical models of NO production in the respiratory system, linear and nonlinear models. Subjects ( n = 32...

Endomorphin analogues with mixed μ-opioid (MOP) receptor agonism/δ-opioid (DOP) receptor antagonism and lacking β-arrestin2 recruitment activity.
Abstract Analogues of endomorphin (Dmt-Pro-Xaa-Xaa-NH2) modified at position 4 or at positions 4 and 3, and tripeptides (Dmt-Pro-Xaa-NH2) modified at position 3, with various phenylalanine analogues (Xaa=Trp, 1-Nal, 2-Nal, Tmp, Dmp, Dmt) were synthesized and their effects on in vitro opioid activity were investigated. Most of the peptides exhibited high μ-opioid (MOP) receptor binding affinity (KiMOP=0.13-0.81nM), modest MOP-selectivity (Kiδ-opioid (DOP)/KiMOP=3.5-316), and potent functional MOP agonism (GPI, IC50=0.274-249nM) without DOP and κ-opioid (KOP) receptor agonism. Among them, compounds 7 (Dmt-Pro-Tmp-...

Modulating Endothelial Barrier Function by Targeting Vimentin Phosphorylation
Vimentin is a major intermediate filament protein in vascular endothelial cells which might be involved in their function as a barrier tissue. It is proposed to dynamically maintain integrity of the endothelium as a tightly regulated permeability barrier that is subjected to a variety of shear and contractile forces. The results described in this report demonstrate that vimentin plays that role through mechanisms that are dependent on its phosphorylation state. Withaferin A (WFA), a vimentin targeting drug is shown to disrupt endothelial barrier function through its effects on vimentin filament distribution and physical pr...

Development of a Respiratory Sensitization/Elicitation Protocol of Toluene Diisocyanate (TDI) in Brown Norway Rats to derive an Elicitation-based Occupational Exposure Level.
Abstract Toluene diisocyanate (TDI), a known human asthmagen, was investigated in skin-sensitized Brown Norway rats for its concentration x time (Cxt)-response relationship on elicitation-based endpoints. The major goal of study was to determine the elicitation inhalation threshold dose in sensitized, re-challenged Brown Norway rats, including the associated variables affecting the dosimetry of inhaled TDI-vapor in rats and as to how these differences can be translated to humans. Attempts were made to duplicate at least some traits of human asthma by using skin-sensitized rats which were subjected to single or mult...

Case report: passive transfer of hepatitis B antibodies from intravenous immunoglobulin
Conclusion: Misinterpretation of serology results following IVIg infusion may lead to significant patient harm, including unnecessary antiviral administration, the withholding of treatments, and psychosocial damage. This is especially pertinent at a time when we have an ever increasing number of patients being treated with IVIg for a wide array of immune-mediated disease. Passive antibody transfer should be considered wherever unexpected serological changes are identified. (Source: BMC Infectious Diseases)

Second-Generation Antipsychotics Cause a Rapid Switch to Fat Oxidation That Is Required for Survival in C57BL/6J Mice
Some second-generation antipsychotics (SGAs) increase insulin resistance and fat oxidation, but counter intuitively they do not activate lipolysis. This seems unsustainable for meeting energy demands. Here, we measured dose-dependent effects of SGAs on rates of oxygen consumption (VO2), respiratory exchange ratio (RER), and physical activity in C57BL/6J mice. The role of H1-histamine receptors and consequences of blocking fat oxidation were also examined. Olanzapine, risperidone, and clozapine (2.5–10mg/kg) elicited rapid drops in dark-cycle RER (~0.7) within minutes, whereas aripiprazole exerted only modest changes....

Mechanisms of Pharmaceutical Aerosol Deposition in the Respiratory Tract.
Abstract Aerosol delivery is noninvasive and is effective in much lower doses than required for oral administration. Currently, there are several types of therapeutic aerosol delivery systems, including the pressurized metered-dose inhaler, the dry powder inhaler, the medical nebulizer, the solution mist inhaler, and the nasal sprays. Both oral and nasal inhalation routes are used for the delivery of therapeutic aerosols. Following inhalation therapy, only a fraction of the dose reaches the expected target area. Knowledge of the amount of drug actually deposited is essential in designing the delivery system or devi...

Rothia mucilaginosa Pneumonia in an Immunocompetent Patient.
Abstract Rothia mucilaginosa is a gram-postive coccus that occurs as part of the normal flora of the oropharynx and upper respiratory tract. Lower respiratory tract infections caused by this organism are rare and usually occur in immunocompromised patients. This is the case of an immunocompetent 47-year-old woman with right upper lobe pneumonia in which R.mucilaginosa was isolated in sputum and bronchial aspirate. Infections caused by this agent in the last four years in our hospital were reviewed. The most common predisposing factor was COPD with bronchiectasis. R.mucilaginosa was identified as the causative agent...

[Seminar] Adult obstructive sleep apnoea
Obstructive sleep apnoea is an increasingly common disorder of repeated upper airway collapse during sleep, leading to oxygen desaturation and disrupted sleep. Features include snoring, witnessed apnoeas, and sleepiness. Pathogenesis varies; predisposing factors include small upper airway lumen, unstable respiratory control, low arousal threshold, small lung volume, and dysfunctional upper airway dilator muscles. Risk factors include obesity, male sex, age, menopause, fluid retention, adenotonsillar hypertrophy, and smoking. (Source: LANCET)

Cross-country variation in additive effects of socio-economics, health behaviors, and comorbidities on subjective health of patients with diabetes
Conclusion: Countries show different profiles of social and behavioral determinants of subjective health among patients with diabetes. Our study suggests that universal programs that assume that determinants of well-being are similar across different countries may be over-simplistic. Thus instead of universal programs that use one protocol for health promotion of patients in all countries, locally designed interventions should be implemented in each country.

Successful treatment of pulmonary hemangioma with propranolol
Summary Pulmonary hemangioma is a rare benign tumor of the lungs. Airway hemangiomas in particular may lead to feeding difficulties, barking cough, stridor, respiratory distress, and even acute airway obstruction. Hence, such hemangiomas usually require early and aggressive treatment; however, the treatment modalities employed so far have been associated with their own co‐morbidities and potential long‐term adverse effects for the developing child. Here, we report a case of 9‐month‐old girl who presented with dyspnea and diagnosed pulmonary hemangioma in the lower lobe of left lung. Propranolol is now used as a fir...

Evolution of primate α and θ defensins revealed by analysis of genomes.
Abstract Defensins are endogenous peptides with cysteine-rich antimicrobial ability that contribute to host defence against bacterial, fungal and viral infections. There are three subfamilies of defensins in primates: α, β and θ-defensins. α-defensins are most present in neutrophils and Paneth cells; β-defensins are involved in protecting the skin and the mucous membranes of the respiratory, genitourinary and gastrointestinal tracts; and θ-defensins are physically distinguished as the only known fully-cyclic peptides of animal origin, which are first isolated from rhesus macaques. All three kinds of defensins...

Induction of CYP1A1, CYP1A2, CYP1B1, increased oxidative stress and inflammation in the lung and liver tissues of rats exposed to incense smoke.
Abstract Incense smoke is increasingly being recognized as a potential environmental contaminant and is linked to malignant and non-malignant respiratory diseases. The detoxification of environmental contaminants including polycyclic aromatic hydrocarbons (PAHs) involves the induction of cytochrome P-450 family enzymes (CYPs) by PAHs. However, the detoxification of PAHs also results in the generation of reactive and unstable intermediary metabolites which are implicated in the oxidative stress, DNA damage, and inflammation. It is unclear whether CYPs are similarly induced by incense smoke, which incidentally contai...

Aging Mesenchymal Stem Cells Fail to Protect due to Impaired Migration and Anti-Inflammatory Response.
Abstract Rationale: Aging is characterized by functional impairment and reduced capacity to respond appropriately to environmental stimuli and injury. With age, there is an increase in the incidence and severity of chronic and acute lung diseases. However, the relationship between age and the lung's reduced ability to repair is far from established and necessitates further research in the field. Objectives: Very little is currently known about age-related phenomena in mesenchymal stem cells (MSC). On account of their ability to protect the endothelium and the alveolar epithelium through multiple paracrine mechanism...
