A Pulmonary Artery Pseudoaneurysm from a Locally Advanced Lung Cancer: A Case Report

Background: Pseudoaneurysms or false arterial aneurysms are infrequent complications that result from direct injury to the vascular wall leading to a single-layer hematoma. The formation of a pulmonary artery pseudoaneurysm secondary to an adjacent lung neoplasm is a rare occurrence.Presentation of Case: We report a patient who developed a pseudoaneurysm of his left pulmonary artery from an infiltrating squamous cell carcinoma of the lung.Conclusion: Despite the relative infrequency, the presence of a pulmonary pseudoaneurysm secondary to a lung cancer continues to have a high mortality. The aneurysm was managed with an endovascular stent with the goal of hemorrhage control. Unfortunately, the presence of the pseudoaneurysm in the context of his rapidly growing squamous cell carcinoma made the patient no longer a candidate for curative surgery, chemotherapy or radiation. After a long discussion on the patient’s wishes and goals of care, he decided for palliative care measures. He was sent home with home oxygen and community supports in order to spend the remaining days with his family

Mandatory Networked ID Scanners in Nightlife Precincts Across Queensland, Australia: Key Stakeholder Perspectives on Policy and Practice

This study explored stakeholder experiences and attitudes regarding the use of ID scanners in licensed venues in Queensland, Australia. In July 2017, the Queensland Government introduced mandatory, networked ID scanners in licensed venues within designated nightlife districts (SNPs). After 10pm, people seeking to enter late-night licensed venues must provide identification, which is verified by the scanner. The scanner also checks whether the patron has any recorded banning notice/s that may preclude entry into the venue. Semi-structured interviews were conducted with 66 key stakeholders and analysed using thematic analysis. Stakeholders reported that ID scanners support the enforcement of patron bans. Their mandated use within SNPs allows for accurate and timely identification of patrons, and may offer benefits with respect to reducing and solving crime, and improving patron behaviours. Some concerns were expressed regarding data privacy and the need to ensure procedural fairness and consistent use. Overall, the study highlighted the importance of ongoing monitoring and refining of ID scanner policy, particularly with respect to where and when scanners are used

The Assessment of Anemia From Attenuation Values of Cranial Venous Drainage on Unenhanced Computed Tomography of the Head

AbstractObjectiveTo determine if prediction of anemia is possible from quantitative analyses of unenhanced cranial computed tomography (CT) images.MethodsA retrospective chart review revealed 101 patients who had hemoglobin and hematocrit levels obtained within 24 hours of an unenhanced cranial CT. Regions of interest were the place on the torcular Herophili (confluence of sinuses) and the left and right transverse sinuses. Attenuation values were correlated with hemoglobin and hematocrit to investigate any possible relationship.ResultsHemoglobin levels were correlated with torcular and transverse sinus attenuation levels. For every 10 Hounsfield unit (HU) increase in torcular attenuation, hemoglobin levels increased by 16.3 g/L (P < .001). When subgroup analysis was performed, by sex, for every 10 HU increase in torcular attenuation, hemoglobin levels increased by 22.6 g/L (P < .001) in men and 8.96 g/L (P < .05) in women.ConclusionThe attenuation values for venous drainage on unenhanced cranial CT constitute a practical adjunct in the assessment of anemia. Given the number of individuals undergoing CT without blood work, this rapid assessment technique for anemia is a convenient means for narrowing possible diagnoses

A mapping review of evaluations of alcohol policy restrictions targeting alcohol-related harm in night-time entertainment precincts

Alcohol-related harm in night-time entertainment precincts (NEPs) is disproportionately high for the amount of alcohol consumed within these areas. Previous evaluations of alcohol restrictions targeting NEPs have often looked at restrictions in isolation and not attempted to create a comprehensive theoretical explanation that takes multiple restrictions into account. The aim of this review is to establish which restrictions have been adequately evaluated in previous literature, and to identify any research which may provide the basis for a theoretical model that explains the interactions between different alcohol restrictions in NEPs and their combined impact on alcohol-related-harm.A mapping review was conducted to plot evaluations of the effectiveness of different alcohol restrictions in NEPs at reducing assault and injury rates (protocol PROSPERO 2017: CRD42017069773). Six databases and 145 websites were searched, results were categorised based on the type of restrictions evaluated: Outlet density, trading hours, lockouts, price, patron bans, and drinks restrictions.Forty-eight articles were identified out of 20,743 returned by the systematic search. Thirty-five of these papers were original works, and 13 reviews. Outlet density was examined in 15 of the papers, trading hours in 30, lockouts in 21, price in 2, patron bans in 7 and drinks restrictions in 15.No pre-existing theoretical models were identified. Outlet density, trading hours, and price restrictions all had evidence that suggested high levels of effectiveness in NEPs and would be suitable for inclusion in a theoretical model. More research is required before attempting to include lockouts, patron bans and drinks restrictions in a theoretical model. Future research should focus on establishing a theoretical model based on evidence of effective alcohol restrictions and gathering an evidence base for under-researched restrictions
