INTRODUCTION: An aviation safety management system should consider and mitigate against all potential risks to flight safety. In addition to in-flight incapacitation, pilots falling below regulatory standards who are assessed as unfit may have represented a risk prior to that assessment. An analysis was undertaken of Class 1 certificate holders to determine factors correlated with unfit assessments.METHODS: Fitness assessments of pre-existing Class 1 certificate holders following medical examinations (to EASA Part-MED standards) or between medicals were studied between 1 January 2016 and 31 December 2019. Assessments where the outcome was ‘fit’ (N= 99,406) were compared with those where the outcome was ‘unfit’ (N= 7925). Analyses for correlation between unfit assessments against age, declared coexisting medical conditions, and the number of days since last assessed as fit were undertaken using SPSS.RESULTS: Unfit assessment likelihood and age were strongly correlated; there is, however, evidence for the ‘healthy worker effect’, with a fall in unfit assessments between 60–65 yr of age. There was no association between coexisting medical condition declaration and the likelihood of becoming unfit. The time interval between a fit and unfit assessment was significantly lower when comparing 20–60 and 61–63 yr old individuals.DISCUSSION: The analysis of unfit assessments shows strong correlation with increasing age and the possible presence of the healthy worker effect among commercial pilots. The decreased time from a previous fit assessment to an unfit assessment supports the reduced certificate validity period of Class 1 applicants over 60 yr of age.Cairns MK.

Comorbid Medical Condition

Introduction: The aim of this study was to describe the nature of regular medications taken by active comorbid scuba divers (having a declared medical comorbidity) and scuba divers and snorkellers who died following a diving incident. Methods: We undertook a retrospective, observational study from July to October, 2020. Data on 268 active comorbid divers were obtained through a 2013 survey of Divers Alert Network Asia-Pacific members. Data on 126 deceased scuba divers and 175 deceased snorkellers were obtained predominantly from 2001–2013 reports to Australian State Coronial Services. Results: The active comorbid divers were significantly older, less likely to be male, and more likely to be taking one or more medications than the two deceased subject groups (P < 0.001). Cardiovascular, endocrine and psychotropic medications accounted for 53.4%, 9.9% and 6.4% of all medications taken, respectively. Almost one tenth of the deceased divers took at least one psychotropic medication, a proportion significantly greater than the other groups (P = 0.01). Conclusions: Medication use among active comorbid divers is common which likely reflects their declared medical condition. Nevertheless, they appear to be diving relatively safely, often with conditions once thought to be absolute contradictions to scuba diving. The deceased divers took significantly more psychotropic medications. It is possible that their underlying psychological/psychiatric conditions rendered them more at risk of a diving incident. Increased vigilance for psychological conditions may need to be considered during diving medical examinations.

<p class="1"><span lang="EN-US">Academic laboratories considered as more hazardous than industry due to relaxed approach of academic management for chemical safety. This study designed to analyze the safe work practices and facilities by Exploratory Factor Analysis (EFA) using Varimax rotation. A designed checklist of 26 safety items administered personally in 68 academic laboratories in a Saudi university. From EFA, five factors were extracted: “Availability of laboratory safety documents (5 items, α = 0.92)”, “Maintenance of fume hood (2 items, α = 0.75)”, “Proper chemical storage (3 items, α = 0.64)”, “Proper use of fume hood for chemical handling (4 items, α = 0.62)” and “Laboratory safety labelling (2 items, α = 0.73)”. The results revealed the 5 factors model that grouped 16 safety items that may be crucial for chemical storage, fume hood, laboratory safety plans and labels in the academic laboratories. The extracted factors derived from EFA are expected to help in the development of chemical safety management in the academic laboratories. </span></p>

Intelligent Model

A man-made catastrophe is considered as an information display of catastrophic development of events in the management system, a peculiar projection of  a man-made catastrophe on the information plane. The paper presents an intellectual model, considers dynamics and ranges of emergency changes in management system parameters, assesses potential risks and  threats  of  catastrophe  emergence.  It  has been  shown  that  at  the  macro-structural  level  for  semantic   description of a catastrophe, it is quite effective to use a tree-like network of scenarios, which displays the conceptual scheme of the subject and problem areas of the catastrophe and is based on judgments of experts, their experience and intuition. This allows probabilistic methods  to  assess  potential  risks  of  a catastrophe using two quantitative indicators: risk (probability) level of  phenomenon occurrence at a certain control point of time and the volume of the expected material loss. It has been suggested that for assessment of possible microstate the fuzzy logic should be applied for each critical object parameter, tolerance limits and functions of affiliation with the fields of fail-safe object functioning should be set by expertise, migration trajectories of relative parameter values should be monitored and terms of their forced return to the working field of regular functioning should be duly provided. Quantitative indicators having imprecise origin have been introduced in the intelligent model of potential risks to assess dynamics of catastrophe threat. One of these indicators is the expert level of catastrophe occurrence during migration of a group of abnormally dangerous parameters of a technical object. The time interval has also been considered which is measured from the current moment to the expected moment of catastrophe occurrence at the preset maximum permissible level of catastrophe threat.

Anxiety about our borders is not a new phenomenon. Distrust of immigrants, external threats, fraud and efforts to secure borders to deflect risky outsiders features prominently in political paranoia today and has since the fortification of state boundaries. This article is concerned with such anxiety and paranoia as it shapes Canadian political discourse, policy and practice in efforts to secure our borders and keep out potential risks. These risks – the poor, the unhealthy, the fraudulent – operate as real concerns for our political elite. Despite liberalized changes to border technologies, specifically citizenship and immigration legislation and practice, I argue that the assumptions about these ‘risks’ remain.

Background and purposeWide-necked bifurcation aneurysms pose a significant challenge to the treating clinician. The Contour Neurovascular System embolization device is a novel tool for the treatment of such intracranial aneurysms. We report on our experience with this device.MethodsProspective clinical and radiological data were collected for all patients treated with the Contour device at our center. All our patients were treated on an elective basis.ResultsWe have treated 11 patients successfully with the Contour device to date. All patients were women with a mean (SD) age of 65.0 (6.4) years. In total, four basilar tip, two internal carotid artery, three middle cerebral artery, one anterior communicating artery, and one superior cerebellar artery aneurysms were treated. At 1-year follow-up, complete occlusion (Raymond Class 1) was seen in 55.56% (5/9) of cases, with 44.44% (4/9) having small neck remnants (Raymond Class 2). One patient declined 1-year catheter angiography and another had no further follow-up due to an unrelated medical condition. For six patients, 2-year radiological follow-up is available and shows stability. At 6 weeks, nine of the 11 patients had a modifed Rankin Scale score of 0, with two patients scoring 1 for headaches. Two patients had thromboembolic events, but there were no complications leading to permanent neurological disability or death. We additionally had three patients where the Contour device was attempted but was unable to be successfully used.ConclusionInitial results are promising although larger case numbers and longer follow-up are necessary to draw further conclusions on the utility and risk profile of this new device.

Construction safety is critical in the success of a project. A considerable amount of effort has been placed on research and practice in order to reduce the potential risks on the construction site. Recent application of electroencephalogram (EEG) to construction research enables researchers to gain insight into construction workers’ physical and mental status during construction tasks. By summarizing existing studies that involve EEG and construction safety, the literature review aims to provide practical suggestions for future research and on-site safety management. The literature search and inclusion process included eleven eligible studies. Comprehensive analysis was conducted based on primary and secondary measures. The primary measures considered the frequency bands of EEG and the channels for detecting electrical activity of the brain. The secondary measures that were involved with physical and mental status with respect to EEG signal variations as a result of task, working hour, and work conditions. Although the field of study that combines EEG measures with construction tasks is still emerging, it is worth continuous attention in the future, as relevant findings would be of great value to the safety management and risk control in the construction industry.

This study evaluated whether patients with somatic symptom disorder, expressing chronic pain that could not be attributed to a medical condition, would benefit from an 8-week inpatient residence at a psychiatric ward. In the 1-year follow-up after termination the authors examined the extent to which the integrated treatment decreased patient costs. A total of 106 patients participated in the follow-up and reported a significant improvement in their general health (Cohen's d = 1.5–2.21), a decrease in impairment due to pain (d = 2.24), and a decrease in symptom severity (d = 1.29). They took fewer medications and sick days, reported fewer hospital stays and medical examinations, and consulted and changed physicians and outpatient clinics less often (d = 0.55–1.1). The average cost per patient was cut in half, down to є 80,000/$96,000 per year. From a clinical standpoint, group analysis that focused on aggression was the most effective intervention.

Introduction. New food safety management systems (FSMS) can contribute to safe production of high quality products that meet the current legal and regulatory standards. The research objective was to develop requirements for a new FSMS, which would make it possible to produce quality pasta made from whole-grain flour and vegetable powders. Study objects and methods. The research featured a whole-grain pasta factory, a technological process of vegetable pasta production, and various elements of FSMS. Results and discussion. The article introduces product description and process flow chart for successful development, implementation, and maintenance of a new FSMS of pasta production. It describes potential physical, chemical, and biological hazards, as well as critical processes. The hazard analysis included probability level and severity of consequences. The study revealed the related unacceptable risks and critical control points, as well as their critical limits. Six critical control points were identified at the stages of kneading, pressing, drying, and stabilization. The paper contains a Hazard Analysis and Critical Control Points (HACCP) plan with a full description of the controlled parameters, their critical limits, monitoring systems, and corrective actions. Conclusion. The new HACCP-based safety management system reduces the response time and increases the responsibility of personnel. It reduces possible losses in case of failures or returns as it improves the product quality. The developed FSMS gives new market options and increases the loyalty of consumers and business partners. As a result, the company becomes more efficient in achieving its goals.
