Anaphylaxis: incidence, presentation, causes and outcome in patients in a tertiary-care hospital in Karachi, Pakistan
Conclusion: Anaphylaxis is a rare but life-threatening condition. Though cutaneous features are most common, their absence does not exclude the diagnosis. Drugs were the most common cause and epinephrine was not commonly used as first-line agent for its management. (Source: QJM)

Tools and Talk: An evolutionary perspective on the functional deficits associated with amyotrophic lateral sclerosis
Abstract We propose that amyotrophic lateral sclerosis (ALS), and frontotemporal dementia may be viewed as a failure of interlinked functional complexes having their origins in key evolutionary adaptations. We discuss how hand‐arm function, locomotion, brain‐stem function (involving vocalization/speech, swallowing and breathing), and cognitive impairment share complex, inter‐dependent evolutionary adaptations that can be traced back several million years. Fine movements of the hand facilitated tool‐making and use enhanced by development of bipedalism. Development of the larynx and integration of respiratory control...

[Neonatal morbidity in early-term newborns.]
CONCLUSIONS: In our environment, there is a significant number of RNTP, which have a significantly higher morbidity than newborns RNTC registered. After individualizing each case, it is essential not end a pregnancy before 39 weeks of gestation, except for maternal, placental or fetal conditions indicating that continuing the pregnancy may increase the risk for the fetus and/or the mother.

Spirometry and Health Status Worsen with Weight Gain in Obese but Improve in Normal-weight Smokers.
Conclusions: Weight gain affects respiratory outcomes differently between obese and normal-weight smokers. While FEV1 and health status decrease with weight gain among obese smokers, they improve among normal-weight smokers. The non-linear relationship between weight gain and respiratory outcomes suggests that this effect of excess weight is unlikely to be mechanical alone.

Evidence for Right Ventricular Lipotoxicity in Heritable Pulmonary Arterial Hypertension.
Conclusions: These data demonstrate that Bmpr2 mutation affects RV stress responses in a transgenic rodent model. Impaired RV hypertrophy and triglyceride and ceramide deposition are present as a function of RV mutant Bmpr2 in mice; fatty acid oxidation impairment in human HPAH RVs may underlie this finding. Further study of how BMPR2 mediates RV lipotoxicity is warranted. PMID: 24274756 [PubMed - as supplied by publisher] (Source: American Journal of Respiratory and Critical Care Medicine)

Eosinophil activities modulate the immune/inflammatory character of allergic respiratory responses in mice
ConclusionsEosinophil contributions to allergic immune/inflammatory responses appear to be limited to the airway challenge and not to the sensitization phase of allergen provocation models. The reversible steroid‐resistant character of the iPHIL neutrophilic airway variant suggests underappreciated mechanisms by which eosinophils shape the character of allergic respiratory responses.

Air pollution and hospital admissions for respiratory diseases in Lanzhou, China.
Abstract Lanzhou is among the most seriously air-polluted cities in China as a whole, due to its unique topography, climate, industrial structure and so on. We studied the relationship between different air pollution and respiratory hospitalizations from 2001 to 2005, the total of respiratory hospital admissions were 28,057. The data were analyzed using Poisson regression models after controlling for the long time trend for air pollutants, the "day of week" effect and confounding meteorological factors. Three air pollutants (PM10, SO2, NO2) had a lag effect, the lag was 3-5 days for PM10, 1-3 days for SO2 and 1-4 d...

Aerially-transmitted human fungal pathogens: What can we learn from metagenomics and comparative genomics?
Abstract In the last few decades, aerially transmitted human fungal pathogens have been increasingly recognized to impact the clinical course of chronic pulmonary diseases, such as asthma, cystic fibrosis or chronic obstructive pulmonary disease. Thanks to recent development of culture-free high-throughput sequencing methods, the metagenomic approaches are now appropriate to detect, identify and even quantify prokaryotic or eukaryotic microorganism communities inhabiting human respiratory tract and to access the complexity of even low-burden microbe communities that are likely to play a role in chronic pulmonary di...

Chest computed tomography for the diagnosis of Mycoplasma pneumoniae infection
We analysed 53 cases of laboratory‐confirmed Mycoplasma pneumoniae infection with cough lasting ≥7 days and chest radiography showing no abnormal findings. Twenty‐two (41%) of those patients showed abnormal findings on chest high‐resolution computed tomography. In the daily clinical setting, for assessment of acute cough, physicians should be aware that it is difficult to confirm bronchiolitis or bronchopneumonia due to M. pneumoniae by chest radiography.

Models for the analysis of repeated continuous outcome measures in clinical trials
Abstract Repeated continuous outcome measures are common in clinical trials. In this tutorial style paper, using data collected from a trial evaluating an intervention for managing asthma and chronic obstructive pulmonary disease, we demonstrate ways of statistically analysing such data to answer frequently encountered clinical research questions. We illustrate the use of linear mixed effects modelling in doing so and discuss its advantages over several other commonly used approaches. The methods described in this paper can easily be carried out using standard statistical software. (Source: Respirology)

Predicting fluid responsiveness in children: a systematic review.
CONCLUSIONS: Respiratory variation in aortic blood flow peak velocity was the only variable shown to predict fluid responsiveness in children. Static variables did not predict fluid responsiveness in children, which was consistent with evidence in adults. Dynamic variables based on arterial blood pressure did not predict fluid responsiveness in children, but the evidence for dynamic variables based on plethysmography was inconclusive.

A retrospective assessment of the incidence of respiratory depression after neuraxial morphine administration for postcesarean delivery analgesia.
Abstract Respiratory depression can occur after neuraxial morphine administration. In the obstetric population, there are little data on respiratory depression after neuraxial morphine administration in women undergoing cesarean delivery. In this single-center, retrospective study in 5036 obstetric patients (mean body mass index = 34 kg/m) who underwent cesarean delivery and received neuraxial morphine, we did not identify any instances of respiratory depression requiring naloxone administration or rapid response team involvement. Therefore, the upper 95% confidence limit for respiratory depression in our study is ...

Apparent Dead Space with the Anesthetic Conserving Device, AnaConDa®: A Clinical and Laboratory Investigation.
CONCLUSIONS: The use of an ACD increases apparent dead space to a greater extent than can be explained by its internal volume. This is caused by adsorption of CO2 in the ACD during expiration and release of CO2 during inspiration. Rebreathing of CO2 was attenuated by moisture. The dead space effect of the ACD could be clinically relevant in acute respiratory distress syndrome and other diseases associated with ventilation difficulties, but investigations with larger sample sizes would be needed to determine the clinical importance.

Effects of flattening filter-free and volumetric-modulated arc therapy delivery on treatment efficiency.
Abstract Flattening filter-free (FFF) beams are available on an increasing number of commercial linear accelerators. FFF beams have higher dose rates than flattened beams of equivalent energy which can lead to increased efficiency of treatment delivery, especially in conjunction with increased FFF beam energy and arc-based delivery configurations. The purpose of this study is to quantify and assess the implications of improved treatment efficiency for several FFF delivery options on common types of linac applicable radiotherapy. Eleven characteristic cases representative of a variety of clinical treatment sites and...

Respiratory Safety Pharmacology - Current Practice and Future Directions.
Abstract Current practice in respiratory safety pharmacology is guided primarily by regulatory requirements as stated in the ICH document S7A. Based on this guidance, it is generally accepted that testing the effects of drugs on ventilatory parameters alone is sufficient to meet regulatory expectations. This strategy needs to be addressed since although ventilatory measurements are capable of assessing the functional status of the respiratory pumping apparatus, such measurements are not capable of assessing the status of the gas exchange unit (lung). The importance of the lung as a target for drug-induced effects i...

The Evolution and Development of Human Swallowing: The Most Important Function We Least Appreciate
As mammals evolved, the larynx accrued added importance in new activities such as effectuating intra-abdominal pressure control during the transition from egg-laying to birthing and control of intrathoracic stabilization as movement of the upper limb required rib stabilization during climbing. The proper development of the larynx during the embryonic period is crucial to its later normal function. The permanent intersection of the respiratory and digestive pathways has created a de novo aerodigestive tract; a first of its kind in mammals. The lowered position of the human larynx has provided a greatly expanded supralarynge...

UWB pulse propagation into human tissues.
Abstract In this paper the propagation of a UWB pulse into a layered model of the human body is studied to characterize absorption and reflection of the UWB signal due to the different body tissues. Several time behaviours for the incident UWB pulse are considered and compared with reference to the feasibility of breath and heartbeat activity monitoring. Results show that if the UWB source is placed far from the human body, the reflection coming from the interface between air and skin can be used to detect the respiratory activity. On the contrary, if the UWB source is placed close to the human body, a small reflec...
