Bigger in Texas: Does That Include The Penal Code Definition of Public Place?

Texas courts have split opinions on the subject, and this Comment will focus on both sides of the argument as to whether places such as front yards and driveways may be considered public places under the Texas Penal Code

Multi-Scale Entropy Analysis as a Method for Time-Series Analysis of Climate Data

Evidence is mounting that the temporal dynamics of the climate system are changing at the same time as the average global temperature is increasing due to multiple climate forcings. A large number of extreme weather events such as prolonged cold spells, heatwaves, droughts and floods have been recorded around the world in the past 10 years. Such changes in the temporal scaling behaviour of climate time-series data can be difficult to detect. While there are easy and direct ways of analysing climate data by calculating the means and variances for different levels of temporal aggregation, these methods can miss more subtle changes in their dynamics. This paper describes multi-scale entropy (MSE) analysis as a tool to study climate time-series data and to identify temporal scales of variability and their change over time in climate time-series. MSE estimates the sample entropy of the time-series after coarse-graining at different temporal scales. An application of MSE to Central European, variance-adjusted, mean monthly air temperature anomalies (CRUTEM4v) is provided. The results show that the temporal scales of the current climate (1960–2014) are different from the long-term average (1850–1960). For temporal scale factors longer than 12 months, the sample entropy increased markedly compared to the long-term record. Such an increase can be explained by systems theory with greater complexity in the regional temperature data. From 1961 the patterns of monthly air temperatures are less regular at time-scales greater than 12 months than in the earlier time period. This finding suggests that, at these inter-annual time scales, the temperature variability has become less predictable than in the past. It is possible that climate system feedbacks are expressed in altered temporal scales of the European temperature time-series data. A comparison with the variance and Shannon entropy shows that MSE analysis can provide additional information on the statistical properties of climate time-series data that can go undetected using traditional method

Bench-to-bedside review: Rare and common viral infections in the intensive care unit – linking pathophysiology to clinical presentation

Viral infections are common causes of respiratory tract disease in the outpatient setting but much less common in the intensive care unit. However, a finite number of viral agents cause respiratory tract disease in the intensive care unit. Some viruses, such as influenza, respiratory syncytial virus (RSV), cytomegalovirus (CMV), and varicella-zoster virus (VZV), are relatively common. Others, such as adenovirus, severe acute respiratory syndrome (SARS)-coronavirus, Hantavirus, and the viral hemorrhagic fevers (VHFs), are rare but have an immense public health impact. Recognizing these viral etiologies becomes paramount in treatment, infection control, and public health measures. Therefore, a basic understanding of the pathogenesis of viral entry, replication, and host response is important for clinical diagnosis and initiating therapeutic options. This review discusses the basic pathophysiology leading to clinical presentations in a few common and rare, but important, viruses found in the intensive care unit: influenza, RSV, SARS, VZV, adenovirus, CMV, VHF, and Hantavirus

National strategy for health research and innovation

In 2011, the Malta Council for Science and Technology (MCST) commissioned the Development of a dedicated strategy for health research and innovation in line with its mandate from Government to identify areas of national priority and design and to also implement strategic approaches to enhance economic competitiveness and quality of life. The Strategy was drawn up by a steering group which also included people from outside the health sector, to ensure that it also keeps note of the economic side of things.peer-reviewe

Congenital Nasal Pyriform Aperture Stenosis Repair: A Case Series and Discussion of Postoperative Care

Congenital nasal pyriform aperture stenosis (CNPAS) is a rare condition related to holoprosencephaly in which bony overgrowth of the medial nasal process of the maxilla narrows the pyriform aperture. CNPAS presents in neonates with signs of upper airway obstruction ranging from mild to severe respiratory distress and failure to thrive. Surgical intervention is indicated after failed conservative measures and generally includes temporary stent placement. We report a series of 3 cases of CNPAS treated surgically, examine postoperative care recommendations in the literature, and present a comprehensive postoperative care regimen with a novel method to maintain stent patency

Extracellular chloride is required for efficient activation of secondary signalling pathways during platelet aggregation

Anion channels perform a diverse range of functions and have been implicated in ATP release, volume regulation and phosphatidylserine exposure. Platelets have been shown to express several anion channels however their function is incompletely understood. Due to a paucity of specific pharmacological blockers, we investigated the global effect of extracellular chloride substitution on platelet activation using aggregometry and flow cytometry. In the absence of extracellular chloride we observed a modest effect on the maximum aggregation response to thrombin or collagen-related peptide. Although the rate of aggregation was substantially reduced in a manner that was dependent on the extracellular chloride concentration, aggregation in the absence of chloride was noticeably biphasic, indicative of impaired secondary signalling. This was further investigated by targeting secondary agonists with aspirin and apyrase or by blockade of the ADP receptor P2Y12. Under these conditions, the rates of aggregation were comparable to those recorded in the absence of extracellular chloride. Finally, we assessed platelet granule release by flow cytometry and report a chloride-dependent element of alpha, but not dense, granule secretion. Taken together these data support a role for anion channels in the efficient induction of platelet activation, likely via enhancement of secondary signalling pathways
