Expression and distribution of sialic acid influenza virus receptors in wild birds.
Abstract Avian influenza (AI) viruses have been detected in more than 105 wild bird species from 12 different orders but species-related differences in susceptibility to AI viruses exist. Expression of α2,3-linked (avian-type) and α2,6-linked (human-type) sialic acid (SA) influenza virus receptors in tissues is considered one of the determinants of the host range and tissue tropism of influenza viruses. We investigated the expression of these SA receptors in 37 wild bird species from 11 different orders by lectin histochemistry. Two isoforms of Maackia amurensis (MAA) lectin, MAA1 and MAA2, were used to detect α...

Lobar torsion after lung transplantation.
Abstract Lobar torsion is a rare complication after lung transplantation. Here we report a case of right middle lobe (RML) torsion after bilateral sequential lung transplantation (BLTx). This 30-year-old lady underwent BLTx for bronchiolitis obliterans due to paraneoplastic pemphigus. The right lower lobe of the donor lung was resected due to inflammatory change during procurement. The postoperative chest X-ray showed persisting RML infiltrates. Fever and leukocytosis were noted 1 week later. RML lobectomy was performed after the reconstructed chest computed tomography confirmed the diagnosis of RML torsion. Adult ...

Pioglitazone acutely reduces energy metabolism and insulin secretion in rats.
In conclusion, pioglitazone acutely induces whole body metabolic slowing and reduces glucose-induced insulin secretion, the latter being largely independent from the insulin-sensitizing action of the drug. The results suggest that pioglitazone has direct metabolic deceleration effects on the β-cell that may contribute to its capacity to lower insulinemia, and anti-diabetic action.

Human metapneumovirus keeps dendritic cells from priming antigen-specific naive T cells.
Abstract Human metapneumovirus (hMPV) is the second cause of acute lower respiratory tract infections in children, causing significant public health burden worldwide. Given that hMPV can repeatedly infect the host without major antigenic changes, it has been suggested that hMPV may have evolved molecular mechanisms to impair host adaptive immunity and more specifically T-cell memory. Recent studies have shown that hMPV can interfere with super antigen-induced T cell activation by infecting conventional dendritic cells (DCs). Here, we show that hMPV infects mouse DCs in a restricted manner and induces, among others ...

The role of hypoxia in pulmonary vascular diseases: a perspective.
Abstract From the discovery of hypoxic pulmonary vasoconstriction, responses to hypoxia have been considered as representative for the many alterations in lung vessels that occur in several chronic lung diseases, including pulmonary hypertension, interstitial pulmonary fibrosis, acute respiratory distress syndrome and COPD. An essential part of preclinical research to explain the pathobiology of these diseases has been centered around the exposure of small and large animals to hypoxia. This review aims to summarize pivotal results of clinical and preclinical research on hypoxia, which still have important implicati...

Macrophage TNFα mediates parathion-induced airway hyperreactivity in guinea pigs.
Abstract Organophosphorus pesticides (OPs) are implicated in human asthma. We previously demonstrated that at concentrations that do not inhibit acetylcholinesterase activity, the OP parathion causes airway hyperreactivity in guinea pigs due to functional loss of inhibitory M2 muscarinic receptors on parasympathetic nerves. Since macrophages are associated with asthma, we investigated whether macrophages mediate parathion-induced M2 receptor dysfunction and airway hyperreactivity. Airway physiology was measured in guinea pigs 24 h after a subcutaneous injection of parathion. Pretreatment with liposome encapsulated ...

Temporary tracheostomy tubes complications
Tracheostomy tubes are used to provide a temporary patent airway in cases with upper respiratory tract obstruction; to allow conscious ventilation when neurological or respiratory function is compromised; to improve surgical access to the mouth or pharynx during anesthesia; or to allow repeated access to diseased lungs. Complications of tracheostomy are reported to occur in 43 to 87% of dogs and cats with either tube or permanent tracheostomy during hospitalization. The reported mortality rate of either tube or permanent tracheostomy in dogs and cats is up to 39%, caused by asphyxiation after tube obstruction or dislodgeme...

Skeletal muscle mitochondrial dysfunction during chronic obstructive pulmonary disease: Central actor and therapeutic target
Abstract Muscle dysfunction is a common complication and an important prognostic factor in chronic obstructive pulmonary disease (COPD). As therapeutic strategies are still needed to treat this complication, gaining more insight into the process that leads to skeletal muscle decline in COPD appears an important issue. This review will focus on mitochondrial involvement in limb skeletal muscle alterations (decreased muscle mass, strength, endurance to work, power and increased fatigue) in COPD. Indeed, mitochondria are the main energy source of the cells, are involved in reactive oxygen species (ROS) production and activ...

Advisory Committee on Immunization Practices (ACIP) Recommended Immunization Schedule for Adults Aged 19 Years and Older - United States, 2013.
Abstract Vaccines are recommended for adults on the basis of age, prior vaccinations, health conditions, lifestyle, occupation, and travel. Current levels of vaccination coverage among adults are low. Health-care providers should be aware of the importance of routinely assessing patients' vaccination histories and recommending and providing routinely recommended vaccines. A strong recommendation from a health-care provider is associated with increased uptake of vaccines. Other interventions shown to increase vaccine uptake, such as implementation of reminder/recall systems and standing orders, have been summarized ...

Breathlessness and cough
Abstract: Breathlessness is a common presentation for a wide range of mainly cardiorespiratory conditions. It can present as a symptom of a life-threatening emergency. In the acute medical setting, the priority is to recognize those patients who are critically unwell and who require emergency treatment. In this group, rapid initial assessment and treatment are essential. However, at some stage, a more thorough assessment is required in all patients to ensure the diagnosis is correct and that on-going treatment and investigations are planned effectively.Cough is a common respiratory symptom that is troublesome for the patie...

Anaesthesia for patients with sickle cell disease (and other haemoglobinopathies)
Abstract: Sickle cell disease is a common inherited disorder of haemoglobin associated with significant morbidity and mortality. It arises from a mutation in chromosome 11, where valine is substituted for glutamic acid, producing an abnormal β globin chain. Under adverse conditions these chains undergo polymerization, leading to deformation of red cells and subsequent sickling crises.Individuals with sickle cell disease have multisystem problems including anaemia, respiratory disease, cardiomegaly, cerebrovascular accident, painful bone disease and renal impairment. Sickle crises may be precipitated by hypoxia, venous sta...

Distribution of Collagen Fiber Orientation in the Human Lung
Collagen fiber, a major component of the extracellular matrix in the human lung, is crucial in maintaining the lung structure mechanically. It is necessary to study the collagen fiber orientation which the mechanical function is closely related to. In the present study the collagen fiber orientation in the lung was quantitatively measured by Osaki's microwave method. We succeeded in preparing sheet samples cut in a coronal direction from the lung for the measurements. It was found that the collagen fibers were, on average, orientated parallel to the longitudinal axis of the spine. The void spaces in the lung sample observe...

Major variations in Aspergillus fumigatus arising within aspergillomas in chronic pulmonary aspergillosis
Summary Aspergillomas develop from progressive layers of mycelial growth on the walls of pulmonary cavities over months. Aspergillomas are characteristic of chronic pulmonary aspergillosis and are a risk factor for azole resistance. We investigated genotypic and phenotypic alterations in Aspergillus fumigatus recovered from aspergillomas. Aspergillomas were removed from three patients (two at surgery, one at autopsy) and dissected. Overall 92 colonies of A. fumigatus were isolated. Microsatellite typing was conducted to determine genetic type. Itraconazole, voriconazole and posaconazole susceptibilities were performed. The...

Effect of contrasted levels of habitual physical activity on metabolic flexibility
The factors regulating the body's ability to switch from fat to carbohydrate oxidation in response to fuel availability changes, or metabolic flexibility (MF), are currently intensively investigated in the context of metabolic diseases. Although numerous metabolic diseases are associated with sedentary behaviors and metabolic inflexibility, the effect of habitual physical activity level (PAL) on MF regulation is surprisingly poorly known. We investigated how PAL affects MF in cross-sectional and interventional studies. MF was assessed in 44 subjects: normal-weight and overweight sedentary men submitted to 2 mo of exercise ...
