Motion Compensation for Ultrasound Thermal Imaging Using Motion-Mapped Reference Model: An in vivo Mouse Study
In this study, we aim to develop a motion compensation method for stable US thermal imaging in in vivo subjects. Based on the assumption that the major tissue motion is approximately periodic caused by respiration, we propose a motion compensation method for change in backscattered energy (CBE) with multiple reference frames. Among the reference frames, the most similar reference to the current frame is selected to subtract the respiratory-induced motions. Since exhaustive reference searching in all stored reference frames can impede real-time thermal imaging, we improve the reference searching by using a motion-mapped ref...

Nasal Oestrosis in a Jamunapari goat
Abstract Oestrus ovis is a well-known parasite of the nasal cavities and adjoining sinuses in sheep and goats. A 3-year-old female Jamunapari goat was presented with a history of anorexia, weight loss, in-coordinated movements, nasal discharge since 10 days and two nasal bots expelled during sneezing 3 days back. Upon clinical examination the animal was dull, dysphonic, unsteady gait and having blocked nostrils with thick mucoid discharge along with an increased respiratory rate. Parasitiological examination revealed it as an O. ovis (nasal bots). The occurrence of nasal bots in a goat an...

GAL-021, a new intravenous BKCa-channel blocker, is well tolerated and stimulates ventilation in healthy volunteers
Conclusions GAL-021 was safe and generally well tolerated with adverse events comparable with placebo except for an infusion site burning sensation. GAL-021 stimulated ventilation at the highest doses suggesting that greater infusion rates may be required for maximum PD effects. GAL-021 had PK characteristics consistent with an acute care medication. (Source: British Journal of Anaesthesia)

Traumatic massive tension pneumothorax due to a break in the middle lobe bronchus
A patient presented respiratory failure and haemodynamic instability after falling from a height of 6 m. After a high suspicion of tension pneumothorax based on clinical status and pulmonary auscultation, the emergency physician inserted a Pneumocath (8 Fr; 2.7 mm) while in the ambulance. Once in hospital, CT scan (figure 1) showed a tension pneumothorax that caused an important left displacement of the heart, right diaphragm and hepatic silhouette. These findings led to replacing the chest tube by a thicker one (Argyle Thoracic Catheter 28 Fr; 9.3 mm). Due to the presence of massive and persistent...

Travel-related MERS-CoV cases: an assessment of exposures and risk factors in a group of Dutch travellers returning from the Kingdom of Saudi Arabia, May 2014
Conclusions: This epidemiological study revealed the complexity of MERS-CoV outbreak investigations with multiple potential exposures to MERS-CoV reported such as healthcare visits, camel exposure, and exposure to untreated food products. Exposure to MERS-CoV during a hospital visit is considered a likely source of infection for Case 1 but not for Case 2. For Case 2, the most likely source could not be determined. Exposure to MERS-CoV via direct contact with animals or dairy products seems unlikely for the two Dutch cases. Furthermore, exposure to a common but still unidentified source cannot be ruled out.

Optogenetic Stimulation of Adrenergic C1 Neurons Causes Sleep State Dependent Cardiorespiratory Stimulation and Arousal with Sighs in Rats.
Conclusions: C1 cell stimulation reproduces most effects of acute hypoxia, specifically cardiorespiratory stimulation, sighs and arousal. C1 cell activation likely contributes to the sleep disruption and adverse autonomic consequences of sleep apnea. During hypoxia (awake) or REM sleep, C1 cell stimulation increases BP but no longer stimulates breathing.

The Airway Colonization by Opportunistic Filamentous Fungi in Patients with Cystic Fibrosis: Recent Updates
Abstract There has been a remarkable increase recently in the isolation of fungi such as Aspergillus fumigatus, species of the Pseudallescheria boydii/Scedosporium apiospermum complex, and Exophiala sp. from the respiratory tract of patients with cystic fibrosis (CF). This review describes the recent insights into the epidemiology, ecology, and physiopathology of the filamentous fungi able to colonize and/or to infect the airways of CF patients, and that may be responsible for accelerated lung function decline. We summarize salient features not only on highly prevalent species such as Aspergillus and Scedosporium,...

Noninvasive Ventilation During Procedural Sedation in the Emergency Department: A Case Series
Procedural sedation and analgesia (PSA) is the administration of sedative, analgesic, or dissociative agents to facilitate painful or unpleasant procedures. The most important complication during PSA is hypoventilation, which may result from compromise of the airway or respiratory drive. While emergency physicians have a conclusive record of safety in using a variety of PSA agents to facilitate painful procedures across the sedation continuum,1 EDs serve an aging population that is burdened with high rates of obesity;2,3 emergency providers are therefore more likely to perform PSA on patients with high anesthetic risk.

On the sociology of
I think I have undervalued the role of horizontal transfer in shaping the genome of Mycobacterium tuberculosis. My excuse for this is that no plasmids have been isolated from M. tuberculosis and that the phylogeny of the M. tuberculosis complex can be explained without invoking any substantive contribution from exogenous DNA. If M. tuberculosis felt that it was okay to ignore horizontal transfer, then I was happy enough to go along with this. It's interesting that the great champions of mycobacterial horizontal transfer–Graham Hatfull for phage and Keith Derbyshire for conjugation – are both graduates of the Nigel G...

The Burden of Influenza-Associated Critical Illness Hospitalizations*
Conclusions: Extrapolating our data to the 2010 U.S. population, we estimate that about 28,000 adults are hospitalized for influenza-associated critical illness annually. Influenza in many of these critically ill patients may be undiagnosed. Critical care physicians should have a high index of suspicion for influenza in the ICU, particularly when influenza is known to be circulating in their communities. (Source: Critical Care Medicine)

Simplified Severe Sepsis Protocol: A Randomized Controlled Trial of Modified Early Goal–Directed Therapy in Zambia*
Conclusion: Factors other than tissue hypoperfusion probably account for much of the end-organ dysfunction in African patients with severe sepsis. Studies of fluid-based interventions should utilize inclusion criteria to accurately capture patients with hypovolemia and tissue hypoperfusion who are most likely to benefit from fluids. Exclusion of patients with severe respiratory distress should be considered when ventilatory support is not readily available. (Source: Critical Care Medicine)

An Unusual Cause of Tree-in-Bud Pattern: Pulmonary Intravascular Tumor Embolism Caused by Chondrosarcoma
We report the case of a 45-year-old man who initially presented with chondrosarcoma of the left femur that was treated surgically. Follow-up chest computed tomography (CT) performed 3 years later showed multiple small nodules with a tree-in-bud branching pattern and larger elongated opacities with beaded contours. These findings raised the suspicion of intravascular tumor embolism. Pulmonary CT angiography demonstrated intravascular thrombosis and dilated and beaded peripheral pulmonary arteries.

Post-transcriptional Silencing of the COX Assembly Factor SURF1 [Molecular Bases of Disease]
Leigh Syndrome (LS) is the most common early-onset, progressive mitochondrial encephalopathy usually leading to early death. The single most prevalent cause of LS is occurrence of mutations in the SURF1 gene, and LSSurf1 patients show a ubiquitous and specific decrease in the activity of mitochondrial respiratory chain complex IV (cytochrome c oxidase, COX). SURF1 encodes an inner membrane mitochondrial protein involved in COX assembly. We established a Drosophila melanogaster model of LS based on the post-transcriptional silencing of CG9943, the Drosophila homolog of SURF1. Knockdown of Surf1 was induced ubiquitously in l...

DosS is Required for the Complete Virulence of Mycobacterium tuberculosis in Mice with Classical Granulomatous Lesions.
Conclusions: DosS, but not DosR and DosT, is required by Mtb to survive in C3HeB/FeJ mice. The attenuation of Δ-dosS is not due to its inability to induce the DosR regulon, nor is it a result of the accumulation of hypoxia. That the in-vivo growth restriction of Δ-dosS could be mimicked ex-vivo suggested sensitivity to macrophage oxidative burst. Anoxic caseous centers within TB lesions eventually progress to cavities. Our results provide greater insight into the molecular mechanisms of Mtb persistence within host lungs.
