Prevalence of Probable Hoarding and Associated Consequences at the Scene of Mississippi Fires, 2009-2019

Background: Increased risk for fire is an often-discussed consequence of hoarding disorder; however, the source of this association has been largely through clinicians’ accounts or hoarding patients’ self-reports.Purpose: The purpose of this study was to investigate the association between probable hoarding and incidence of fires using archival data from Mississippi.Methods: Incidents of residential fires from 2009-2019 were provided by the Mississippi State Fire Marshal’s Office. Fires that were classified as having “a significant amount of fire load present” were classified as probable hoarding fires for analysis.Results: Of the 5,194 unique residential fires identified across the study period, 96 fires (1.9% of all residential fires) were classified as potentially linked to hoarding. Compared to fires not classified as probable hoarding fires, probable hoarding fires were more likely to have at least one individual injured (8.3% vs 5.2%) and to have one or more deaths (4.2% vs 2.1).Conclusion: Our results suggest that the recorded prevalence of probable hoarding at the scene of residential fires in the state of Mississippi is lower than national estimates of the incidence of hoarding; however, residential fires with probable hoarding conditions appear to be more deadly than other fires

The use of acute oxygen supplementation upon muscle tissue saturation during repeat sprint cycling

This study examined performance and physiological responses (power output, tissue saturation index) to repeat sprint cycling with oxygen supplementation (O2Supp [fraction of inspired oxygen 1.00]). Fourteen amateur male cyclists took part. Two visits to the laboratory entailed; 15min relative intensity warm-up, 10min of passive recovery, followed by 10x15s repeated sprints, during which air inspired had FiO21.00 oxygen or normal air. Outcome measures include, mean power (W) and change in Tissue Saturation Index (ΔTSI%). Repeated measures ANOVA were used to examine difference between conditions in mean power output. Paired samples t-tests were used to examine differences between conditions in ΔTSI (%) and rate of muscle reoxygenation and deoxygenation (%·s-1). Mean power output was 4% higher in the oxygen condition compared to normoxia (p<.01). There was a significant positive correlation between power output and reoxygenation rate during O2Supp (r=0.65, p=.04). No correlation was seen between power output and reoxygenation rate during normoxia (r=-0.30, p=.40). A significantly increased deoxy rate was seen in the O2Supp condition compared to normoxia (p=.05). Oxygen supplementation appears to elicit the greatest performance improvements in mean power, potentially facilitated by an increasing muscle reoxygenation rate. This evidences the utility of oxygen as an ergogenic aid to in cycling performance

Carbon Structure Hazard Control

Carbon composite structures are widely used in virtually all advanced technology industries for a multitude of applications. The high strength-to-weight ratio and resistance to aggressive service environments make them highly desirable. Automotive, aerospace, and petroleum industries extensively use, and will continue to use, this enabling technology. As a result of this broad range of use, field and test personnel are increasingly exposed to hazards associated with these structures. No single published document exists to address the hazards and make recommendations for the hazard controls required for the different exposure possibilities from damaged structures including airborne fibers, fly, and dust. The potential for personnel exposure varies depending on the application or manipulation of the structure. The effect of exposure to carbon hazards is not limited to personnel, protection of electronics and mechanical equipment must be considered as well. The various exposure opportunities defined in this document include pre-manufacturing fly and dust, the cured structure, manufacturing/machining, post-event cleanup, and post-event test and/or evaluation. Hazard control is defined as it is applicable or applied for the specific exposure opportunity. The carbon exposure hazard includes fly, dust, fiber (cured/uncured), and matrix vapor/thermal decomposition products. By using the recommendations in this document, a high level of confidence can be assured for the protection of personnel and equipment

Relationship Between Self-Esteem and Athletic Participation

The purpose of this study was to examine the correlation between one’s participation in athletics and levels of self-esteem. Researchers wanted to examine if a person’s participation in competitive sports led to higher levels of self-esteem as opposed to those who do not participate in organized or competitive sports. Participants were found using convenience sampling exclusively on the campus of a religiously affiliated university. A survey was created electronically using the program Qualtrics. The survey measured athletic participation by asking participants how many competitive sports they were participants of. Self-esteem was measured using the Rosenberg Self-Esteem Scale. A sample of 98 total surveys were used from the surveys completed (no sports = 28; one sport = 55; two sports = 10; three sports = 1; four or more sports = 4) and the data were analyzed using SPSS. The mean score on the self-esteem scale was 36.82 (SD=5.93). For the sports participation scale it was 1.96 (SD=0.90). Results indicate a moderate positive correlation was found between the two variables, r (98) = .330, p \u3c .001 supporting the hypothesis that there is a positive correlation between athletic participation and self-esteem. One of the limitations of this study is that its sample was taken exclusively from one religiously affiliated university which is not representative of the entire population of college students or athletes. However, future studies done using participants of religiously affiliated institutions may explore the impact religious beliefs have on self-esteem

Cerebrovascular Reactivity Change with Increased Intracranial Pressure

Cerebrovascular reactivity (CVR) is an important regulatory factor of the brain. The parameter controls the dilation and constriction of blood vessels in the brain in response to certain stimuli, such as carbon dioxide. Abnormal CVR values could potentially be indicators of poorly functioning regulatory systems. Testing of CVR is one method of assessing the brain\u27s regulatory capabilities. The purpose of this study was to test for a relationship between CVR and intracranial pressure (ICP). In this study, increased intracranial pressure was created in 4 female subjects through head down tilt, using an inversion table. Subjects were lowered in the table and secured in 15 degree increments, from positive 45 degrees, to negative 30 degrees. At each level, a breath holding test was performed to measure CVR. In the breath holding test, the subject breathed normally for 30 seconds, held their breath for 30 seconds, and breathed normally for 30 seconds while blood flow velocity was recorded in the middle cerebral artery. The subject’s blood pressure was taken at each level of the table. The blood flow velocities from the middle cerebral artery were used to calculate the subject’s CVR value for each angle. The CVR values were observed to not change significantly at different angles of the inversion table. As mean arterial pressure was also observed to have remained unchanged through the various angles of the inversion table, it was confirmed that ICP was being increased

Mutually-Antagonistic Interactions in Baseball Networks

We formulate the head-to-head matchups between Major League Baseball pitchers and batters from 1954 to 2008 as a bipartite network of mutually-antagonistic interactions. We consider both the full network and single-season networks, which exhibit interesting structural changes over time. We find interesting structure in the network and examine their sensitivity to baseball's rule changes. We then study a biased random walk on the matchup networks as a simple and transparent way to compare the performance of players who competed under different conditions and to include information about which particular players a given player has faced. We find that a player's position in the network does not correlate with his success in the random walker ranking but instead has a substantial effect on its sensitivity to changes in his own aggregate performance.Comment: A few clarifications added 14 pages, 2 tables, 6 figures.

Self-care self-efficacy, religious participation and depression as predictors of poststroke self-care among underserved ethnic minorities

Underserved ethnic minorities have multiple chronic disease risk factors, including tobacco, alcohol and substance use, which contribute to increased incidence of stroke. Self-efficacy (self-care self-efficacy), religious participation and depression may directly and indirectly influence engagement in post stroke self-care behaviors. The primary aim of the present study was to investigate the effects of self-care self-efficacy, religious participation and depression, on tobacco, alcohol and substance use in a sample of largely ethnic minority, underserved stroke survivors (n=52). Participants previously recruited for a culturally tailored secondary stroke prevention self-care intervention were included. The treatment group received three stroke self-care sessions. The usual care group completed assessments only. Both groups were included in these analyses. Main outcome measures included tobacco, alcohol and substance use. Self-care self-efficacy, religious participation and depression were also assessed. Logistic regression analyses, using self-efficacy, religious practice and depression as the referents, were used to predict binary outcomes of tobacco, alcohol and substance use at 4-weeks post-stroke. Higher depression and self-care self-efficacy were associated with reduced odds of smoking and substance use. Greater participation in religious activities was associated with lower odds of alcohol use. We can conclude that incorporating depression treatment and techniques to increase self-care self-efficacy, and encouraging religious participation may help to improve stroke self-care behaviors for underserved and low socioeconomic status individuals. Results are discussed in the context of stroke self-management
