Inappropriate electrolyte repletion for patients undergoing endoscopic procedures

At Thomas Jefferson University Hospital (TJUH), there has been a perceived necessity among housestaff and fellows to routinely check and replete serum potassium and magnesium for inpatients prior to endoscopic procedures In addition, there was an unwritten policy that these electrolytes needed to be aggressively repleted, with a goal potassium above 4.0 and magnesium above 2.0 Contributing factors include absence of clear policy, fear of adverse outcomes during procedures, and fear of delay of procedures leading to increased hospital stay This practice has led to unwarranted lab draws, costs of lab tests and electrolyte riders, and possible delayed procedures Goals Clarify policies regarding electrolyte repletion Determine frequency of inappropriate electrolyte checking and repletion Determine monetary cost of this action Decrease frequency of inappropriate electrolyte lab check and repletionhttps://jdc.jefferson.edu/patientsafetyposters/1023/thumbnail.jp

Sono, estresse e comportamentos compensatórios por enfermeiras e parteiras australianas

OBJECTIVE: To describe sleep, stress and compensatory behaviors in nurses and midwives. METHODS: The study included 41 midwives and 21 nurses working in Australian hospitals between 2005 and 2009. Participation was voluntary. All participants recorded on a daily basis their work and sleep hours, levels of stress and exhaustion, caffeine intake and use of sleep aids for a month (1,736 days, 1,002 work shifts). RESULTS: Participants reported moderate to high levels of stress and exhaustion on 20-40% of work days; experienced sleep disruption on more than 50% of work days; struggled to remain awake on 27% of work days; and suffered extreme drowsiness or experienced a near accident while travelling home on 9% of workdays. Age, perceived sleep duration and work hours were significant predictors of caffeine intake. About 60% of participants reported using sleep aids (about 20% reported taking prescription medications and 44% of nurses and 9% of midwives reported alcohol use as a sleep aid at least once during the study). Stress and workdays were significant predictors of sedative use. Overall, 22% reported being indifferent or mildly dissatisfied with their job. CONCLUSIONS: Sleep problems, high levels of stress and exhaustion and low job satisfaction are prevalent among nurses and midwives. The use of alcohol and sleeping pills as sleep aids, and the use of caffeine to help maintain alertness is also common. Nurses and midwives may use caffeine to compensate for reduced sleep, especially on workdays, and sleeping pills to cope with their daily work-related stress.OBJETIVO: Describir sueño, estrés y comportamientos compensatorios en enfermeras y parteras. MÉTODOS: El estudio incluyó 41 enfermeras 21 parteras en hospitales australianos de 2005 a 2009. La participación fue voluntaria. Los participantes registraron diariamente las horas de trabajo, sueño, estrés y niveles de agotamiento, cafeína y uso de ayuda para dormir durante un mes (1.736 días, 1.002 turnos). RESULTADOS: Los participantes relataron de moderados a elevados niveles de estrés y de agotamiento en 20%-40% de los días de trabajo; experimentaron disturbios del sueño en más de 50% de los días de trabajo; relataron esfuerzo para permanecer despierto en 27% de los días de trabajo; y sofrieron somnolencia extrema o accidente cerca de casa en 9% de los días de trabajo. Edad, duración del sueño percibido y jornadas fueron predictores significativos de la ingestión de cafeína. Aproximadamente 60% de los participantes relataron utilizar la ayuda para dormir: cerca de 20% usaron de medicación prescripta y 44% de las enfermeras y 9% de las parteras consumirán alcohol como auxilio para dormir al menos una vez durante el estudio. Estrés y días de trabajo fueron predictores significativos del uso de sedativos. En general, 22% relataron ser indiferente, o ligeramente insatisfecho con su trabajo. CONCLUSIONES: Problemas en el sueño, estrés y agotamiento elevados y disminución en la satisfacción en el trabajo son prevalecientes. Uso de alcohol y de medicamentos para dormir, y consumo de cafeína para mantenerse alerta también es común. Enfermeras y parteras pueden usar la cafeína para compensar la reducción del sueño, especialmente en días de trabajo, y usar somníferos para compensar el estrés diario.OBJETIVO: Descrever sono, estresse e comportamentos compensatórios em enfermeiras e parteiras.

Explanation of the Colour Change in Alexandrites.

Alexandrites are remarkable and rare gemstones. They display an extraordinary colour change according to the ambient lighting, from emerald green in daylight to ruby red in incandescent light from tungsten lamps or candles. While this colour change has been correctly attributed to chromium impurities and their absorption band in the yellow region of the visible light spectrum, no adequate explanation of the mechanism has been given. Here, the alexandrite effect is fully explained by considering the von Kries model of the human colour constancy mechanism. This implies that our colour constancy mechanism is real (objective) and primarily attuned to correct for the colour temperature of black-body illuminants

Increasing Employee Awareness of the Signs and Symptoms of Heart Attack and the Need to Use 911 in a State Health Department

INTRODUCTION: Early recognition of the signs and symptoms of a heart attack can lead to reduced morbidity and mortality. METHODS: A workplace intervention was conducted among 523 Montana state health department employees in 2003 to increase awareness of the signs and symptoms of heart attack and the need to use 911. All employees received an Act in Time to Heart Attack Signs brochure and wallet card with their paychecks. Act in Time posters were placed in key workplace areas. A weekly e-mail message, including a contest entry opportunity addressing the signs and symptoms of heart attack, was sent to all employees. Baseline and follow-up telephone surveys were conducted to evaluate intervention effectiveness. RESULTS: Awareness of heart attack signs and symptoms and the need to call 911 increased significantly among employees from baseline to follow-up: pain or discomfort in the jaw, neck, or back (awareness increased from 69% to 91%); feeling weak, light-headed, or faint (awareness increased from 79% to 89%); call 911 if someone is having a heart attack or stroke (awareness increased from 84% to 90%). Awareness of chest pain, pain or discomfort in the arms or shoulders, and shortness of breath were more than 90% at baseline and did not increase significantly at follow-up. At baseline, 69% of respondents correctly reported five or more of the signs and symptoms of heart attack; 89% reported correctly at follow-up. CONCLUSION: This low-cost workplace intervention increased awareness of the signs and symptoms of heart attack and the need to call 911

The decision to moonlight: does second job holding by the self-employed and employed differ?

This paper considers drivers of second job holding amongst the self-employed in comparison with the employed. Econometric analysis of panel data explores whether the self-employed are more or less likely to take on a second job when already running their own business, than their employed counterparts. The findings contribute to the literature through identification of a need-based variable – difficulty in meeting housing costs – as a key driver of movements from self-employment to hybrid entrepreneurship. Findings, further, identify different patterns of second job holding by gender, particularly amongst self-employed individuals

Guiding principles for determining work shift duration and addressing the effects of work shift duration on performance, safety, and health

The article of record as published may be found at http://dx.doi.org/10.1093/sleep/zsab161Risks associated with fatigue that accumulates during work shifts have historically been managed through working time arrangements that specify fixed maximum durations of work shifts and minimum durations of time off. By themselves, such arrangements are not sufficient to curb risks to performance, safety, and health caused by misalignment between work schedules and the biological regulation of waking alertness and sleep. Science-based approaches for determining shift duration and mitigating associated risks, while addressing operational needs, require: 1) a recognition of the factors contributing to fatigue and fatigue-related risks; 2) an understanding of evidence-based countermeasures that may reduce fatigue and/or fatigue-related risks; and 3) an informed approach to selecting workplace-specific strategies for managing work hours. We propose a series of guiding principles to assist stakeholders with designing a shift duration decision-making process that effectively balances the need to meet operational demands with the need to manage fatigue-related risks.Academy of Sleep Medicine (AASM)Sleep Research Societ

Comparative distribution of dopamine D-1 and D-2 receptors in the basal ganglia of turtles, pigeons, rats, cats, and monkeys

The distribution and density of dopamine D-1 and D-2 receptors were studied in the basal ganglia of adult turtles, pigeons, rats, cats, and monkeys. Dopamine receptors were measured in vitro by quantitative autoradiography in alternate sections processed for D-1 and D-2 receptor subtypes and compared to adjacent sections stained for acetylcholinesterase (AChE) activity. [ 3 H]-SCH 23390 and [ 3 H]-spiroperidol were used to label the D-1 and D-2 dopamine receptor subtypes, respectively. The anatomic distribution of both D-1 and D-2 receptors in the basal ganglia was remarkably similar across all species examined. Whereas the absolute number of D-1 and D-2 receptors in the basal ganglia varied between species, the percentage of D-1 and D-2 receptors in a region was quite similar among species. The pattern of binding to the D-1 and D-2 receptor varied among the different species. The adult turtles, pigeons, and rats demonstrated non-patchy D-1 and D-2 receptor binding in the striatum and pallidum. The adult cat and monkey caudate nucleus and putamen demonstrated mildly heterogeneous receptor binding in a pattern that differed from that seen with AChE staining, but did occasionally demonstrate similar patterns of the D-1 and D-2 receptor subtypes, The immature cat striatum was characterized by heterogeneous D-1 receptor binding that corresponded to heterogeneous AChE rich patches, whereas D-2 receptor binding was homogeneous. Heterogeneous binding was seen in other basal ganglia structures including the nucleus accumbens, olfactory tubercle, and substantia nigra pars compacta and reticulata. Complementary D-1 and D-2 receptor binding patterns were seen in the pallidum and substantia nigra of the mammals. The results of this study indicate that both D-1 and D-2 dopamine receptors are present in the basal ganglia of five different vertebrates. A common feature of dopamine receptors in the basal ganglia is their heterogeneity in distribution and density. The heterogeneity of dopamine receptors has similarities to and differences from the distribution of presynaptic dopamine and other neurotransmitter markers of the basal ganglia.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/50037/1/902620308_ftp.pd

An application of Extended Normalisation Process Theory in a randomised controlled trial of a complex social intervention: process evaluation of the Strengthening Families Programme (10-14) in Wales, UK

Purpose: Process evaluations generate important data on the extent to which interventions are delivered as intended. However, the tendency to focus only on assessment of pre-specified structural aspects of fidelity has been criticised for paying insufficient attention to implementation processes and how intervention-context interactions influence programme delivery. This paper reports findings from a process evaluation nested within a randomised controlled trial of the Strengthening Families Programme 10–14 (SFP 10–14) in Wales, UK. It uses Extended Normalisation Process Theory to theorise how interaction between SFP 10–14 and local delivery systems - particularly practitioner commitment/capability and organisational capacity - influenced delivery of intended programme activities: fidelity (adherence to SFP 10–14 content and implementation requirements); dose delivered; dose received (participant engagement); participant recruitment and reach (intervention attendance). Methods: A mixed methods design was utilised. Fidelity assessment sheets (completed by practitioners), structured observation by researchers, and routine data were used to assess: adherence to programme content; staffing numbers and consistency; recruitment/retention; and group size and composition. Interviews with practitioners explored implementation processes and context. Results: Adherence to programme content was high - with some variation, linked to practitioner commitment to, and understanding of, the intervention’s content and mechanisms. Variation in adherence rates was associated with the extent to which multi-agency delivery team planning meetings were held. Recruitment challenges meant that targets for group size/composition were not always met, but did not affect adherence levels or family engagement. Targets for staffing numbers and consistency were achieved, though capacity within multi-agency networks reduced over time. Conclusions: Extended Normalisation Process Theory provided a useful framework for assessing implementation and explaining variation by examining intervention-context interactions. Findings highlight the need for process evaluations to consider both the structural and process components of implementation to explain whether programme activities are delivered as intended and why

'To live and die [for] Dixie': Irish civilians and the Confederate States of America

Around 20,000 Irishmen served in the Confederate army in the Civil War. As a result, they left behind, in various Southern towns and cities, large numbers of friends, family, and community leaders. As with native-born Confederates, Irish civilian support was crucial to Irish participation in the Confederate military effort. Also, Irish civilians served in various supporting roles: in factories and hospitals, on railroads and diplomatic missions, and as boosters for the cause. They also, however, suffered in bombardments, sieges, and the blockade. Usually poorer than their native neighbours, they could not afford to become 'refugees' and move away from the centres of conflict. This essay, based on research from manuscript collections, contemporary newspapers, British Consular records, and Federal military records, will examine the role of Irish civilians in the Confederacy, and assess the role this activity had on their integration into Southern communities. It will also look at Irish civilians in the defeat of the Confederacy, particularly when they came under Union occupation. Initial research shows that Irish civilians were not as upset as other whites in the South about Union victory. They welcomed a return to normalcy, and often 'collaborated' with Union authorities. Also, Irish desertion rates in the Confederate army were particularly high, and I will attempt to gauge whether Irish civilians played a role in this. All of the research in this paper will thus be put in the context of the Drew Gilpin Faust/Gary Gallagher debate on the influence of the Confederate homefront on military performance. By studying the Irish civilian experience one can assess how strong the Confederate national experiment was. Was it a nation without a nationalism
