Full Text Available Abstract Background In February, 2007, the Associated Press (AP conducted a poll of 1,002 adults in the United States about their attitudes towards the war in Iraq. Respondents were remarkably accurate estimating the current death toll of US soldiers, yet were grossly inaccurate in estimating the current death toll of Iraqi civilians. We conducted a search of newspapers reports to determine the extent of the discrepancy between reporting Coalition and Iraqi civilian deaths, hypothesizing that there would be an over-representation of Coalition deaths compared to Iraqi civilian deaths. Methods We examined 11 U.S. newspapers and 5 non-U.S. newspapers using electronic databases or newspaper web-archives, to record any reports between March 2003 and March 2008 of Coalition and Iraqi deaths that included a numeric indicator. Reports were described as "events" where they described a specific occurrence involving fatalities and "tallies" when they mentioned the number of deaths over a period of time. We recorded the number of events and tallies related to Coalition deaths, Iraqi civilian deaths, and Iraqi combatant deaths Results U.S. newspapers report more events and tallies related to Coalition deaths than Iraqi civilian deaths, although there are substantially different proportions amongst the different U.S. newspapers. In four of the five non-US newspapers, the pattern was reversed. Conclusion This difference in reporting trends may partly explain the discrepancy in how well people are informed about U.S. and Iraqi civilian fatalities in Iraq. Furthermore, this calls into question the role of the media in reporting and sustaining armed conflict, and the extent to which newspaper and other media reports can be used as data to assess fatalities or trends in the time of war.

Full Text Available Several studies have been conducted to investigate the grammatical errors of Iraqi postgraduates and undergraduates in their academic writing. However, few studies have focused on the writing challenges that Iraqi pre-university students face. This research aims at examining the written discourse of Iraqi high school students and the common grammatical errors they make in their writing. The study had a mixed methods design. Through convenience sampling method, 112 compositions were collected from Iraqi pre-university students. For purpose of triangulation, an interview was conducted. The data was analyzed using Corder’s (1967 error analysis model and James’ (1998 framework of grammatical errors. Furthermore, Brown’s (2000 taxonomy was adopted to classify the types of errors. The result showed that Iraqi high school students have serious problems with the usage of verb tenses, articles, and prepositions. Moreover, the most frequent types of errors were Omission and Addition. Furthermore, it was found that intralanguage was the dominant source of errors. These findings may enlighten Iraqi students on the importance of correct grammar use for writing efficacy.

2018-04-01

Full Text Available The current study aims at analysing the improper pronunciation of Iraqi EFL learners concerning the pronunciation of diphthongs in words of various syllables. It describes and identifies thoroughly the mispronunciations of such important sounds in English language. The study attempts at analysing such mispronunciations by clarifying and assigning the phonetic deviations of Iraqi EFL learners when they pronounce diphthongs. So the main objective of the study is to analyse the errors committed by Iraqi learners in the pronunciation of diphthongs grouping each error into its specific category. To verify the objective of the paper, 25 Iraqi EFL learners from the department of English at Cihan University/ Slemani are chosen to be the main participants of the study. The test which was conducted in the laboratory of the Department of English contained 10 words comprising various diphthongs. The results clearly revealed that mispronouncing English diphthongs by Iraqi EFL were mostly observed by replacing the required diphthong with another improper one and they also tended to use simple vowels instead of the correct required diphthongs.

Full Text Available 【Abstract】Objective: To determine the pattern of causalities of Iraqi ballistic missile attacks on Tehran, the capital of Iran, during Iraq-Iran war. Methods: Data were extracted from the Army Staff Headquarters based on daily reports of Iranian army units during the war. Results: During 52 days, Tehran was stroked by 118 Al-Hussein missiles (a modified version of Scud missile. Eighty-six missiles landed in populated areas. During Iraqi missile attacks, 422 civilians died and 1 579 injured (4.9 deaths and 18.3 injuries per missile. During 52 days, 8.1 of the civilians died and 30.4 injured daily. Of the cases that died, 101 persons (24% were excluded due to the lack of information. Among the remainders, 179 (55.8% were male and 142 (44.2% were female. The mean age of the victims was 25.3 years±19.9 years. Our results show that the high accuracy of modified Scud missiles landed in crowded ar-eas is the major cause of high mortality in Tehran. The pres-ence of suitable warning system and shelters could reduce civilian casualties. Conclusion: The awareness and readiness of civilian defense forces, rescue services and all medical facilities for dealing with mass casualties caused by ballistic missile at-tacks are necessary. Key words: Mortality; War; Mass casualty incidents; Wounds and injuries

The Tuwaitha site, 20 km south of Baghdad, was chosen at the beginning of the sixties to be the Center for Research and Development of the Iraqi Nuclear Program. The israeli air attack to the Osirak reactor in 1981, the clandestine activities for nuclear weapons production and the inspections carried out by the International Atomic Energy Agency (IAEA) to verify such activities are parts of the history of that nuclear complex. Its installations were extensively damaged in 1991 during the so called Golf War and finally destroyed by air bombardment during the invasion by the Coalition Forces in 2003. The IAEA and other several countries have elaborated an international assistance program for the future activities of installations dismantling and site remediation. (author) [es

War violates every human right of children. In recent years, the lives of Iraqi children and the livelihoods of their families have become precarious. Conflict has split the communities where they live and taken the lives of hundreds of their friends and family members. The literature focuses on the negative effects of armed conflict on Iraqi children, and the steps that need to be taken to ameliorate their condition by adapting evidence based but culturally sensitive measures. A comprehensive solution to child protection problems clearly will take time. The primary need for the protection of Iraqi children is an end to conflict. Family and educational order and social stability are central to efforts to achieve progress in child protection. Solutions to armed conflict and its aftermath work best when they are responsive to local cultural practices and beliefs, and are drawn from an understanding of child development. Child safety, security and well-being should be in the forefront of the national agenda to ensure a more positive future both economically and socially to achieve a healthier Iraq.

'Jail break' made by Iraqi oil tankers

2000-01-01

The implications of Iran's policy turn-about of allowing ships smuggling Iraqi crude oil to sail through its coastal waters, out of reach of UN and US ships patrolling the Persian Gulf, are discussed. It is suspected that the change in Iranian policy may be due to the fact that an infusion of Iraqi oil on the international markets would suit Iran's purposes by reducing the need for OPEC to raise production quotas. Iran is known to be opposed to an increase of production by OPEC members. At the same time, developments in US-Iranian relations and in the international oil market also have to be considered as factors influencing the Iranian position on this issue

The Iraqi civil registration system and the test of political upheaval

Directory of Open Access Journals (Sweden)

Sulaiman Bah

2014-04-01

Full Text Available An in-depth situation analysis was carried out on the Iraqi civil registration system in 2011, years after the end of the military operation of 2003. The study was done using a combination of methods, including interviews with key role players in the Iraqi civil registration system, observation, study of documents, triangulation, and gap analysis. The study found the civil registration system in Iraq to be largely intact and functional, in spite of the wars experienced in Iraq over the past three decades. Given that civil registration systems generally get destroyed through wars, the paper discusses the reasons for the resilience in the Iraqi civil registration system and draws lessons from them.

Warrior Resilience Training in Operation Iraqi Freedom: combining rational emotive behavior therapy, resiliency, and positive psychology.

Science.gov (United States)

Jarrett, Thomas

2008-01-01

Warrior Resilience Training (WRT) is an educational class designed to enhance Warrior resilience, thriving, and posttraumatic growth for Soldiers deployed in Operation Iraqi Freedom. Warrior Resilience Training uses rational emotive behavior therapy (REBT), Army leadership principles, and positive psychology as a vehicle for students to apply resilient philosophies derived from Army Warrior Ethos, Stoic philosophy, and the survivor and resiliency literature. Students in WRT are trained to focus upon virtue, character, and emotional self-regulation by constructing and maintaining a personal resiliency philosophy that emphasizes critical thinking, rationality, virtue, and Warrior Ethos. The author, an Army licensed clinical social worker, executive coach, REBT doctoral fellow, and former Special Forces noncommissioned officer, describes his initial experience teaching WRT during Operation Iraqi Freedom to combat medics and Soldiers from 2005 to 2006, and his experience as a leader of a combat stress control prevention team currently in Iraq offering mobile WRT classes in-theater. Warrior Resilience Training rationale, curriculum, variants (like Warrior Family Resilience Training), and feedback are included, with suggestions as to how behavioral health providers and combat stress control teams might better integrate their services with leaders, chaplains, and commands to better market combat stress resiliency, reduce barriers to care, and promote force preservation. Informal analysis of class feedback from 1168 respondents regarding WRT reception and utilization is examined.

Full Text Available Analysis of the Israel's Foreign Policy is one of the important issues concerned by the researchers of the international and regional affairs. Israel's Foreign Policy in years 2003-2015 has witnessed a lot of events. In these years, transformation of the Iraq's internal structures including the fall of the Baath Regime in Iraq and appearance of the terroristic group of Dashi (ISIS in this country has provided new opportunities and challenges for the Israel's Foreign Policy. In this regard, establishment of a republic system in Iraq and the reinforcement of the Kurdish streams, specially during the current transformations and the increasing desires for the independence in Iraqi's Kurdistan, have paved the way for Israel to intensify its activities in the region. In this regard, the current study has approach the issue of Israel's Foreign Policy concerning Iraqi's Kurdistan during the years 2003-2015 with a descriptive analytic method. The achieved results show that the political reasons (alliance of the periphery and development of the strategic depth in closeness to Iran, economic (accessing the energy and mineral resources in Iraqi's Kurdistan, the importance of the Kurdistan's hydro-politic resources for Israel and the Israel's economical influence from the Nile to the Euphrates, military-security (presence in the strategic environment of Iran and the external threats in the Middle East, creation of an environmental crisis un the Kurdish region of the Middle East, weakening the Iraqi's central government and disintegration of this country, Israel's security-intelligence expansion, acquiring a strategic territory and getting out of isolation and the resolving the its legitimacy crisis, controlling the currents of thought in this region, all have been influential in thein Israel's Foreign Policy Concerning Iraqi's Kurdistan.

To identify access barriers to healthcare and potential interventions to improve access for Iraqi refugee children. Four focus groups were conducted using consecutive sampling of Iraqi refugee parents residing in the US for 8 months to 5 years. Eight key-informant interviews also were conducted with employees of organizations serving Iraqi refugee families, recruited using snowball sampling. Focus groups and interviews were audiotaped, transcribed, and analyzed using margin coding and grounded theory. Iraqi refugees identified provider availability, Medicaid maintenance and renewal, language issues, and inadequate recognition of post-traumatic stress disorder as barriers to care for their children. Interviewees cited loss of case-management services and difficulties in understanding the Medicaid renewal process as barriers. Potential interventions to improve access include community-oriented efforts to educate parents on Medicaid renewal, obtaining services, and accessing specialists. Given the enduring nature of language and Medicaid renewal barriers, policies addressing eligibility alone are insufficient.

Night-Time Light Dynamics during the Iraqi Civil War

Full Text Available In this study, we analyzed the night-time light dynamics in Iraq over the period 2012–2017 by using Visible Infrared Imaging Radiometer Suite (VIIRS monthly composites. The data quality of VIIRS images was improved by repairing the missing data, and the Night-time Light Ratio Indices (NLRIs, derived from urban extent map and night-time light images, were calculated for different provinces and cities. We found that when the Islamic State of Iraq and Syria (ISIS attacked or occupied a region, the region lost its light rapidly, with the provinces of Al-Anbar, At-Ta’min, Ninawa, and Sala Ad-din losing 63%, 73%, 88%, and 56%, of their night-time light, respectively, between December 2013 and December 2014. Moreover, the light returned after the Iraqi Security Forces (ISF recaptured the region. In addition, we also found that the night-time light in the Kurdish Autonomous Region showed a steady decline after 2014, with the Arbil, Dihok, and As-Sulaymaniyah provinces losing 47%, 18%, and 31% of their night-time light between December 2013 and December 2016 as a result of the economic crisis in the region. The night-time light in Southern Iraq, the region controlled by Iraqi central government, has grown continuously; for example, the night-time light in Al Basrah increased by 75% between December 2013 and December 2017. Regions formerly controlled by ISIS experienced a return of night-time light during 2017 as the ISF retook almost all this territory in 2017. This indicates that as reconstruction began, electricity was re-supplied in these regions. Our analysis shows the night-time light in Iraq is directly linked to the socioeconomic dynamics of Iraq, and demonstrates that the VIIRS monthly night-time light images are an effective data source for tracking humanitarian disasters in that country.

For more than a decade, mild induced hypothermia (32 °C-34 °C) has been standard of care for patients remaining comatose after resuscitation from out-of-hospital cardiac arrest with an initial shockable rhythm, and this has been extrapolated to survivors of cardiac arrest with initially nonshockable rhythms and to patients with in-hospital cardiac arrest. Two randomized trials published in 2002 reported a survival and neurological benefit with mild induced hypothermia. One recent randomized trial reported similar outcomes in patients treated with targeted temperature management at either 33 °C or 36 °C. In response to these new data, the International Liaison Committee on Resuscitation Advanced Life Support Task Force performed a systematic review to evaluate 3 key questions: (1) Should mild induced hypothermia (or some form of targeted temperature management) be used in comatose post-cardiac arrest patients? (2) If used, what is the ideal timing of the intervention? (3) If used, what is the ideal duration of the intervention? The task force used Grading of Recommendations Assessment, Development and Evaluation methodology to assess and summarize the evidence and to provide a consensus on science statement and treatment recommendations. The task force recommends targeted temperature management for adults with out-of-hospital cardiac arrest with an initial shockable rhythm at a constant temperature between 32 °C and 36 °C for at least 24 hours. Similar suggestions are made for out-of-hospital cardiac arrest with a nonshockable rhythm and in-hospital cardiac arrest. The task force recommends against prehospital cooling with rapid infusion of large volumes of cold intravenous fluid. Additional and specific recommendations are provided in the document.

Studies have examined the potential benefits and risks of alternative forms of detention, such as house arrest, for adults but, despite its growing use, little research has examined the implications of house arrest for juveniles. The current research examined the experience of 14 adolescents under house arrest. Six main themes were identified in the narratives of the participants: the experience of detention, daily schedule and utilization of time, emotions and self-reflection, relationships with peers, relation to parents and supervisor(s), and contact with professionals. Findings emphasized the potential developmental dangers of house arrest at the critical stage of adolescence. Yet, analysis also showed that the period of house arrest has the potential to be a period of positive changes, and can be used for successful rehabilitation.

Many Iraqi refugees suffer from posttraumatic stress. Efficient, culturally sensitive interventions are needed, and so we adapted narrative exposure therapy into a brief version (brief NET) and tested its effects in a sample of traumatized Iraqi refugees. Iraqi refugees in the United States reporting elevated posttraumatic stress (N = 63) were randomized to brief NET or waitlist control conditions in a 2:1 ratio; brief NET was 3 sessions, conducted individually, in Arabic. Positive indicators (posttraumatic growth and well-being) and symptoms (posttraumatic stress, depressive, and somatic) were assessed at baseline and 2- and 4-month follow-up. Treatment participation (95.1% completion) and study retention (98.4% provided follow-up data) were very high. Significant condition by time interactions showed that those receiving brief NET had greater posttraumatic growth (d = 0.83) and well-being (d = 0.54) through 4 months than controls. Brief NET reduced symptoms of posttraumatic stress (d = -0.48) and depression (d = -0.46) more, but only at 2 months; symptoms of controls also decreased from 2 to 4 months, eliminating condition differences at 4 months. Three sessions of brief NET increased growth and well-being and led to symptom reduction in highly traumatized Iraqi refugees. This preliminary study suggests that brief NET is both acceptable and potentially efficacious in traumatized Iraqi refugees. Copyright © 2014 International Society for Traumatic Stress Studies.

Circulatory Arrest, Brain Arrest and Death Determination

Directory of Open Access Journals (Sweden)

Sam David Shemie

2018-03-01

Full Text Available Technological advances, particularly in the capacity to support, replace or transplant failing organs, continue to challenge and refine our understanding of human death. Given the ability to reanimate organs before and after death, both inside and outside of the body, through reinstitution of oxygenated circulation, concepts related to death of organs (e.g. cardiac death are no longer valid. This paper advances the rationale for a single conceptual determination of death related to permanent brain arrest, resulting from primary brain injury or secondary to circulatory arrest. The clinical characteristics of brain arrest are the permanent loss of capacity for consciousness and loss of all brainstem functions. In the setting of circulatory arrest, death occurs after the arrest of circulation to the brain rather than death of the heart. Correspondingly, any intervention that resumes oxygenated circulation to the brain after circulatory arrest would invalidate the determination of death.

Full Text Available Several studies have indicated that the range and linguistics expressions of external modifiers available in one language differ from those available in another language. The present study aims to investigate the cross-cultural differences and similarities with regards to the realization of request external modifications. To this end, 30 Iraqi and 30 Malay university students are selected as the participants of this study. Spencer-Oatey's (2008 rapport management theoretical framework is used to examine how face rapport is managed through the use of external modifications. The corpus consists of responses to a Discourse Completion Test (DCT consisting of eight situations. The questionnaires, adopted from Rose (1994, were distributed among Iraqi students and Malaysian Malay students studying at Universiti Sains Malaysia, Malaysia. The corpus were then analyzed based on Blum-Kulka, House and Kasper (1989 classification of external modifiers. The primary objective of this paper is to compare the effect of situational factors on the realization patterns of request modification between Iraqi and Malay university students .The findings are hoped to have implications for comparative cross-cultural and intercultural communication studies.

2017-02-01

Full Text Available This study examines the influence of liquidity on the profitability of Iraqi commercial banks. Five banks based in Iraq namely: North bank, Iraqi Islamic bank, Sumer bank, Dar Es-Salam bank and Babylon bank randomly selected and analyzed for the current study over the period 2005 to 2013. Moreover,  annual reports of these banks have studied and the main ratios of profitability and liquidity were calculated. These reports are available at Iraqi Stock Exchange site. The variables that were identified as independent for liquidity were, loan deposit ratio, deposit asset ratio and cash deposit ratio, while return on assets as dependent variable for profitability. The Ordinary Least Square (OLS model used to examine the impact of liquidity on profitability. The study observes that any increase in liquidity ratios as above mentioned will lead return on asset to increase as well. Depending on this study it could be better for Iraqi banks to keep a balance between liquidity and profitability.

This study was conducted to identify the predictors, levels, and prevalence of anxiety and stress and to assess the relationship between these factors and quality of life in recently displaced Iraqis. A cross-sectional design was used. A convenience sample of 171 Iraqi refugees was recruited. The results indicated that more than half of the sample suffered from high anxiety levels, while 42.8% reported high stress. The regression model explained 46.3% of the variance in levels of quality of life. Unemployment, fewer than three family members, and high anxiety significantly predicted low-level quality of life. These three predictors need to be taken into consideration when developing health-related interventions to improve the quality of life of Iraqi refugees. © 2017 John Wiley & Sons Australia, Ltd.

More than 63,000 Iraqi refugees were resettled in the United States from 1994 to 2010. We analyzed data for all US-bound Iraqi refugees screened in International Organization for Migration clinics in Jordan during June 2007-September 2009 (n = 18,990), to describe their health profile before arrival in the United States. Of 14,077 US-bound Iraqi refugees ≥ 15 years of age, one had active TB, 251 had latent TB infection, and 14 had syphilis. No HIV infections were reported. Chronic diseases comorbidities accounted for a large burden of disease in this population: 35% (n = 4,105) of screened Iraqi refugees had at least one of three chronic medical conditions; hypertension, diabetes mellitus, or obesity. State health departments and clinicians who screen refugees need to be aware of the high prevalence of chronic diseases among Iraqi refugees resettled in the United States. These results will help public health specialists develop policies to reduce morbidity and mortality among US-bound Iraqi refugees.

[Manpower migrations and Arab unity: the challenges of the Iraqi model].

Science.gov (United States)

Roussillon, A

1985-01-01

Iraq occupies a unique position in the system of manpower exchanges between Middle Eastern states brought about by the rise in petroleum incomes of the 1970s. Iraq was among the most important oil exporters until the war with Iran, but its economy is predominantly agricultural, it is a rich country in terms of available financial resources, and it is both an importer and exporter of labor, traits which place it squarely between the nonoil-producing states which are poor and overpopulated and the oil exporters which are rich and underpopulated. Its migration policy, which radically distinguishes between Arab and non-Arab manpower, is also unique. Data on migration to Iraq are very sparse despite the fact that the nation has a good data-gathering capacity. Estimates of migration to Iraq and employment patterns of migrants have varied widely and have contradicted each other in crucial respects. The most unusual aspect of Iraqi immigration policy, the free access offered to Egyptians and other Arabs, has hampered attempts to estimate the volume of migration, as workers come and go for relatively short periods, seeking their own employment in Iraq and working in jobs for which they may be overqualified. Official formulations of Iraqi migration policy insist that migration should not only be beneficial to individual importing and exporting countries in terms of development and social cohesion, but should also reinforce the solidarity and regional complementarity of the Arab world as a whole. Iraqi migration policy is presented as expressing the most fundamental choices of the "Arab revolution" in the socialist dimension of Arab unitary ideology rather than in terms of immediate national economic interest. Iraqi legislation grants non-Iraqi Arabs the same labor, residence, investment, and ultimately naturalization rights as those enjoyed by nationals, but severely restricts access to employment and other rights of non-Arab foreigners.

Antimicrobial resistance is a serious global health concern. It has considerable implications on societies' health and resources. In Jordan, there is a large Iraqi community due to the ongoing turmoil in Iraq. Unfortunately, health awareness and practices of this community are under-investigated due to scarcity of research. This paper assesses the awareness of antibiotic use and antimicrobial resistance in the Iraqi community residing in Amman, Jordan. Their level of interaction with health care professionals regarding antibiotics and differences in their antibiotic use between Iraq and Jordan are also discussed. A cross-sectional questionnaire-based survey involving randomly selected Iraqis residing in Amman, Jordan was conducted. The study involved 508 participants. Sixty-two percent of participants agreed with buying antibiotics without a prescription, 29% agreed with obtaining antibiotics from friends or relatives, and 46% agreed with keeping leftover antibiotics for future use. Furthermore, 60% disagreed with not completing an antibiotic course and almost 90% of the sample listed viral diseases as an indication for antibiotics. Forty-four percent of participants abided by physicians' instructions on antibiotic use. Half of the participants believed that pharmacists provided instructions on antibiotics all the time, whereas physicians were perceived to do so by 29% of participants. Gaps exist in knowledge of antibiotic use and reasons for antimicrobial resistance among Iraqis residing in Jordan. These gaps should serve in planning educational campaigns to raise the community's awareness of responsible antibiotic use. Law enforcement to restrict access to antibiotics is also pivotal to tackle their misuse.

The medical infrastructure of Iraqi Kurdistan, a semiautonomous region in the northern part of Iraq, lags disproportionately behind relative to the otherwise booming industrial advances of the region. Although neurosurgical training is available, the local population lacks trust in its own neurosurgeons. Medical facilities suffer from a lack of basic resources, such as high-speed drills, intracranial pressure monitoring, and stereotaxy to care for neurosurgical patients. Since 2012, American volunteer neurosurgeons have delivered lectures and mentored local neurosurgeons in performing neurosurgical procedures. Over the last 4 years, the visiting neurosurgical team has seen hundreds of patients in consultation and performed more than 50 complex cranial and spinal operations jointly with local neurosurgeons. This article discusses our experience as volunteer neurosurgeons in building neurosurgical capacity in Iraqi Kurdistan. Copyright © 2016 Elsevier Inc. All rights reserved.

An engineering interpretation of pop-in arrest and tearing arrest in terms of static crack arrest, Ksub(Ia)

International Nuclear Information System (INIS)

Witt, F.J.

1983-01-01

When fracture toughness specimens are tested under displacement controlled conditions, they are often observed to exhibit unstable cleavage fracture followed by arrest of the cleavage mode wherein a significant load remains on the specimen (pop-in arrest). This behavior carries over into the ductile tearing regime wherein tearing may occur rapidly identified by load reduction and then proceeds at a discernible less rate (tearing arrest). Both these behaviors represent an initiation condition followed by an arrest condition. In this paper it is demonstrated that from either of the arrest conditions an arrest value may be determined which, for available experimental data, is shown to be an engineering estimate for the static crack arrest toughness, Ksub(Ia). A data analysis procedure is outlined and Ksub(Ic) and Ksub(Ia) estimates from sixty-eight 1/2, 1 and 2 in. thick compact specimens from two steels (A533 Grade B Class 1 and AISI 1018) tested between -40 deg F and 200 deg F are summarized. The crack arrest estimates are seen to compare favorably with Ksub(Ia) results obtained by other investigators using 2 in. thick specimens. Also it is demonstrated that when failure is by fully ductile tearing, the crack arrest toughness is at least equal to the estimate for Ksub(Ic) for the specimen. (author)

The United Nations High Commissioner for Refugees (UNHCR) recognizes 43.7 million forcibly displaced persons and asylum seekers due to conflict and persecution worldwide. Neurological disorders have rarely been described in displaced persons but likely pose a significant burden of disease. We describe the disease spectrum and health service utilization of Iraqi refugees and asylum seekers with neurological disorders using an information system developed by the UNHCR. Neurological disorders were actively monitored among the 7,642 UNHCR-registered Iraqi refugees and asylum seekers who received health and humanitarian assistance using a pilot, centralized, database called the Refugee Assistance Information System (RAIS) in the Kingdom of Jordan in 2010. There were 122 neurological diagnoses reported in 1,328 refugees (mean age 41 years, 49% female, 10% disabled, 43% with pending resettlement applications) in 2,659 health visits, accounting for 17% of all refugees who sought health assistance in RAIS. Referral to a neurologist occurred in 178 cases (13.4%). The most frequent ICD-10 neurological diagnoses were dorsalgia (back pain) (29.7% of individuals with neurological disorders), headache (13.1%), and epilepsy (12.6%). Approximately 1 in 20 Iraqi refugees with a neurological diagnosis self-reported a history of torture, which was higher than Iraqi refugees without a history of torture [66/1,328 versus 196/6,314, odds ratio (OR) = 1.63, 95% confidence interval (CI) 1.21-2.18]. Neurological disease affects a high proportion of Iraqi refugees, including victims of torture and the disabled. Refugees require dedicated care for treatment of neurological disease with a focus on pain disorders and epilepsy.

The data of sieve analysis (215 samples of aggregates being obtained from of National Central Construction Laboratory and Technical College Construction Laboratory in Kirkuk city have analyzed using the statistical program SAS. The results showed that 5%, 17%, and 18% of fine aggregate samples are passing sieve sizes 10 mm, 4.75 mm, and 2.36 mm, respectively, which were less than the minimum limit allowed by the Iraqi specifications for each sieve. The percentages passing sieve sizes 1.18mm, 600micrometers, and 300micrometers were more than the upper limit of specification by 5%, 20%, and 30% respectively. The samples were passing sieve sizes 1.18mm, and 600micrometers less than the minimum limit of specification by 17%, and 4%, respectively. The results showed that the deviation in a sieve size of 150 micrometers for the upper limit of the specification performs 2% of the total number of samples. For Coarse aggregate, the samples passing sieves size 37.5mm and 20mm were comforting the Iraqi specifications by 100% and 83% respectively, it has found that the samples were passing sieve sizes 10 mm was 5% was more than the higher limit of Iraqi specifications, and 27% of these samples were less than the minimum limit, whereas sample passing sieve size 5mm was 1% which is more than the upper limit of the Iraqi specification. As a result of statistical analysis of data for fine aggregate, it has found that the samples were passing sieve sizes 10 mm, 2.36 mm, 1.18 mm and 150micrometers conforming from statistical point of view the Iraqi specifications, whereas the samples were passing sieve sizes 4.75 mm, 600micrometers and 300 micrometers didn’t conform.

A vibration protection system under consideration consists of a payload connected to a vibrating housing by shape memory alloy (SMA) slotted springs. To provide an arrest function two permanent magnets are inserted into the system. The slotted SMA elements are preliminary deformed in the martensitic state. Activation of one element by heating initiates force and displacement generation, which provide an arrest of the payload by magnets. The magnets also secure the arrest mode after cooling of the SMA element. Activation of the other element results in uncaging of the payload and switching to the vibration isolation mode. Computer simulations of arrest and uncaging when the housing is quiescent or producing sine-wave displacements were carried out. Functional-mechanical behavior of SMA parts was described by means of a microstructural model.

Biomechanics of fall arrest using the upper extremity: age differences.

This study tried to isolate critical biomechanical factors in fall arrests using the upper extremity during simulated forward falls. This study also attempted to find the differences in those factors between young and old age groups. The role of the upper extremity is not well defined despite its primary usage as a local shock absorber during fall impact. Comparative study in which two age groups underwent motion analysis.Methods. Ten healthy older males (mean age, 66.4 years) and 10 young males (mean age, 24.1 years) volunteered to perform self-initiated and cable-released falls at selected falling distances, while the joint motion and impact forces at the hand were recorded. Significant age differences were demonstrated in joint kinematics and impact force parameters at close distances. Excessive reflexive responses of the upper extremity in cable-released falls for the older adults resulted in 10-15 times higher peak impact forces and 2-3 times shorter body braking time than in self-initiated falls. Pre-impact activities of the upper extremity predispose the post-impact response during fall arrests. Suppressing excessive pre-impact reflexive activation of the arms could efficiently decrease the risk of fall-related injuries, which calls for securing sufficient arm movement time. Any fall prevention strategy that can increase arm movement time would be effective against injuries of the upper extremity during falling in the older adults. The findings will help to understand underlying mechanisms of fall arrest using the upper extremity for prevention of fall-related fractures.

As dispersed ethnic populations in Swedish society expand, the healthcare system need to adapt rehabilitation services according to their needs. The experiences of trauma and forced resettlement have a continuing impact on health and musculoskeletal pain, as well as the intersecting structures that prerequisite the possibilities in the new country. To understand the specific needs of women from the Iraqi diaspora in Sweden, there is a need to elucidate the effects of pain on their everyday life. To elucidate everyday life with chronic pain from the perspective of women from the Iraqi diaspora in Sweden. Qualitative interview study according to Glaser's grounded theory. The results from 11 interviews suggest that pain was associated with dependency on society as well as on family. It resulted in a struggle for sense of control, framed by faith in God, influenced by the healthcare system, and with support from family. The women's testimony of lack of continuity of care, resulting in recollection of lived traumas in every visit, is a vital sign of the unconscious power relations within health care and how representatives from health care, instead of being the ones who help the women forward, become the ones who hold them back. The results show the importance of challenging the normative assumptions embedded in health care and treatment for patients with chronic pain and of including the voice of "others".

The Iraq conflict resulted in the largest displacement in the Middle East in recent history, and provision of health services to the displaced population presents a critical challenge. With an increase in the number of people affected by complex emergencies and the number of people displaced in urban settings, the international community must adapt intervention strategies to meet the specific demands and contexts of this population. The study aimed to provide information on food security and livelihoods for Iraqi refugees in Syria and Jordan to inform humanitarian assistance planning. National cross-sectional cluster sample surveys of displaced Iraqi populations displaced were conducted in Jordan (October 2008) and Syria (March 2009). Clusters of ten households were randomly selected using probability-based sampling; a total of 1200 and 813 Iraqi households in Jordan and Syria, respectively, were interviewed about food security and receipt of humanitarian assistance. In Syria, 60% of households reported the household food situation had declined since the arrival period as compared to 46% in Jordan. Food aid receipt was reported by 18.0% of households in Jordan and 90.3% of households in Syria. In Jordan, 10.2% of households received cash assistance and in Syria 25.3% of households received cash assistance. In Jordan, cash assistance was associated with low socioeconomic status, large household size, and UNHCR registration. In Syria, female headed households, Damascus residents, families with children, and those registered with UNHCR were more likely to receive cash assistance. Food insecurity remains a concern among displaced Iraqi households in both Jordan and Syria. Improved targeting of both food and cash assistance and the expansion of cash-based programs could lead to a more effective use of funds and facilitate the implementation of assistance programs that are sustainable in the context of declining funding availability.

A year into the 2003 US-Iraq war, how were adolescents in Baghdad faring? Conflict-related events typically lower psychological well-being; in contrast, investment in and protection of threatened identities should lead to self-esteem striving and, presumably, better well-being. How threatened do Iraqi adolescents feel? Is their self-esteem related to their sense of threat? Do age, religion, ethnicity, and gender alter the link between perceived threat and self-esteem? We use data from 1000 randomly selected adolescents living in Baghdad during July 2004. Iraqi adolescents reported high levels of threat; those feeling more threatened reported higher levels of self-esteem. Social background correlates with both self-esteem and perceived threat, but controlling for social background does not eliminate the relationship between self-esteem and perceived threat. We interpret our results in light of theory and research concerning social identity, mortality threats, and war trauma.

Iraqi dates (Zahdi and Khestawi) were irradiated at different dose levels (0 to 1500 krad) to extend their shelf-lives. Samples irradiated at 150 krad showed no change in the behaviour studies of tested Swiss albino mice. Fungi were found to have a constant rate of growth on the syrup irradiated dates. Chemical products such as malondialdehyde, deoxy sugars, acids and reducing sugars were quantified. In conclusion, 150 krad is a convenient dose to extend the shelf-lives of the tested dates and is therefore recommended. (author)

This study investigated differences in mental health knowledge and beliefs between participants from the Iraqi and Sudanese refugee communities, and Australian-born individuals, in Sydney, Australia. Ninety-seven participants were given vignettes of characters describing symptoms of major depressive disorder and posttraumatic stress. They were required to identify psychological symptoms as disorders, rate beliefs about the causes of and helpful treatments for these disorders, and rate attitude statements regarding the two characters. Australian participants recognized the presented symptoms as specific mental disorders significantly more than Iraqi and Sudanese participants did, and reported causal and treatment beliefs which were more congruent with expert beliefs as per the western medical model of mental disorder. The Sudanese group endorsed supernatural and religious causal beliefs regarding depression and posttraumatic stress symptoms most often; but both Sudanese and Iraqi participants strongly supported options from the supernatural and religious treatment items. However, evidence for pluralistic belief systems was also found. Although sampling was non-random, suggesting caution in the interpretation of results, it appears that the mental health literacy of lay Australians may be more aligned with the western medical model of mental disorder than that of Iraqi and Sudanese refugee communities. Mental health literacy support needs of Iraqi and Sudanese refugee communities resettled in western countries such as Australia might include education about specific symptoms and causes of mental disorder and the effectiveness of psychiatric treatments. These findings provide useful directions for the promotion of optimal service utilization among such communities.

Pragmatic Difficulties in the Production of the Speech Act of Apology by Iraqi EFL Learners

Full Text Available The purpose of this paper is to investigate the pragmatic difficulties encountered by Iraqi EFL university students in producing the speech act of apology. Although the act of apology is easy to recognize or use by native speakers of English, non-native speakers generally encounter difficulties in discriminating one speech act from another. The problem can be attributed to two factors: pragma-linguistic and socio-pragmatic knowledge. The aim of this study is(1to evaluate the socio-pragmatic level of interpreting apologies as understood and used by Iraqi EFL university learners, (2 find out the level of difficulty they experience in producing apologies and(3 detect the reasons behind such misinterpretations and misuses. It is hypothesized that the socio-pragmatic interpretation of apology tends to play a crucial role in comprehending what is intended by the speaker. However, cultural gaps can be the main reason behind the EFL learners' inaccurate production of the act of apology. To verify the aforementioned hypotheses, a test has been constructed and administered to a sample of 70 fourth-year Iraqi EFL university learners, morning classes. The subjects' responses have been collected and linguistically analyzed in the light of an eclectic model based on Deutschmann (2003 and Lazare (2004. It has been concluded that the misinterpretation or difficulty Iraqi EFL students have faced is mainly attributed to their lack of socio-pragmatic knowledge. The interference of the learnersʹ first language culture has led to non-native productions of speech act of apology.

Brief dynamic-model tests have been made at the request of the Federal Aviation Agency to investigate the use of a shallow pond of water at the end of a runway as a means of arresting jet-transport aircraft when they are forced to abort on take-off or overrun on landing. Such a scheme is of particular interest for civil aircraft because it requires no modifications or attachments to the airplane and no mechanical devices in the arresting system. A modification of this scheme that uses a flexible plastic cover over the water surface has also been tested. The purpose of this paper is to present the results of a dynamic model investigation which would aid in determining whether the water-pond arresting system could be used as a means of arresting airplane overrun.

Poor self-rated health is an estimator of quality of life and a predictor of mortality seldom studied in immigrant populations. This work aimed to study self-rated health in relation to social capital, socioeconomic status, lifestyle and comorbidity in immigrants from Iraq - one of the largest non-European immigrant group in Sweden today - and to compare it with the self-rated health of native Swedes. The study was a cross-sectional population-based study conducted from 2010 to 2012 among citizens of Malmö, Sweden, aged 30-65 years and born in Iraq or Sweden. All participants underwent a health examination and answered questionnaires on self-rated health, social capital, comorbidity, lifestyle and socioeconomic status. In total, 1348 Iraqis and 677 Swedes participated. Poor self-rated health was identified in 43.9% of Iraqis and 21.9% of native Swedes ( psocial capital was highly prevalent in the immigrants. Female gender showed higher odds of poor self-rated health in Iraqis than in Swedes (OR 1.8, 95% CI 1.4-2.5, p interaction =0.024), independent of other risk factors connected to social capital, socioeconomic status, lifestyle or comorbidity. Although public health initiatives promoting social capital, socioeconomic status and comorbidity in immigrants are crucial, the excess risk of poor self-rated health in Iraqi women is not fully attributed to known risk factors for self-rated health, but remains to be further explored.

This paper reports that Iraq is making progress in putting its battered petroleum industry back together 1 1/2 years after the Persian Gulf war ended. OPEC News Agency (Opecna) reported the finish of reconstruction of Iraq's Mina al-Bakr oil terminal on the northern tip of the Persian Gulf, using Iraqi know-how and engineering personnel. The terminal, heavily damaged during the gulf conflict, has been restored to its prewar loading capacity of 1.6 million b/d at a cost of $16 million. Ninety per cent of the port had been damaged

To examine breast-feeding and complementary feeding practices during the first 6 months of life among Norwegian infants of Somali and Iraqi family origin. A cross-sectional survey was performed during March 2013-February 2014. Data were collected using a semi-quantitative FFQ adapted from the second Norwegian national dietary survey among infants in 2006-2007. Somali-born and Iraqi-born mothers living in eastern Norway were invited to participate. One hundred and seven mothers/infants of Somali origin and eighty mothers/infants of Iraqi origin participated. Breast-feeding was almost universally initiated after birth. Only 7 % of Norwegian-Somali and 10 % of Norwegian-Iraqi infants were exclusively breast-fed at 4 months of age. By 1 month of age, water had been introduced to 30 % of Norwegian-Somali and 26 % of Norwegian-Iraqi infants, and infant formula to 44 % and 34 %, respectively. Fifty-four per cent of Norwegian-Somali and 68 % of Norwegian-Iraqi infants had been introduced to solid or semi-solid foods at 4 months of age. Breast-feeding at 6 months of age was more common among Norwegian-Somali infants (79 %) compared with Norwegian-Iraqi infants (58 %; P=0·001). Multivariate analyses indicated no significant factors associated with exclusive breast-feeding at 3·5 months of age. Factors positively associated with breast-feeding at 6 months were country of origin (Somalia) and parity (>2). Breast-feeding initiation was common among Iraqi-born and Somali-born mothers, but the exclusive breast-feeding period was shorter than recommended in both groups. The study suggests that there is a need for new culture-specific approaches to support exclusive breast-feeding and complementary feeding practices among foreign-born mothers living in Norway.

Crack arrest within teeth at the dentinoenamel junction caused by elastic modulus mismatch

Bechtle, Sabine

2010-01-01

Enamel and dentin compose the crowns of human teeth. They are joined at the dentinoenamel junction (DEJ) which is a very strong and well-bonded interface unlikely to fail within healthy teeth despite the formation of multiple cracks within enamel during a lifetime of exposure to masticatory forces. These cracks commonly are arrested when reaching the DEJ. The phenomenon of crack arrest at the DEJ is described in many publications but there is little consensus on the underlying cause and mecha...

During the last two decades, the Iraqi human resources for health was exposed to an unprecedented turnover of trained and experienced medical professionals. This study aimed to explore prominent factors affecting turnover intentions among Iraqi doctors. A descriptive cross-sectional multicentre study was carried out among 576 doctors across 20 hospitals in Iraq using multistage sampling technique. Participants completed a self-administered questionnaire, which included socio-demographic information, work characteristics, the 10-item Warr-Cook-Wall job satisfaction scale, and one question on turnover intention. Descriptive and bivariate and multiple logistic regression analyses were conducted to identify significant factors affecting turnover intentions. More than one half of Iraqi doctors (55.2%) were actively seeking alternative employment. Factors associated with turnover intentions among doctors were low job satisfaction score (odds ratio (OR) = 0.97; 95% confidence interval (CI): 0.95, 0.99), aged 40 years old or less (OR = 2.9; 95% CI: 1.74, 4.75), being male (OR = 4.2; 95% CI: 2.54, 7.03), being single (OR = 5.0; 95% CI: 2.61, 9.75), being threatened (OR = 3.5; 95% CI: 1.80, 6.69), internally displaced (OR = 3.1; 95% CI: 1.43, 6.57), having a perception of unsafe medical practice (OR = 4.1; 95% CI: 1.86, 9.21), working more than 40 h per week, (OR = 2.3; 95% CI: 1.27, 4.03), disagreement with the way manager handles staff (OR = 2.2; 95% CI: 1.19, 4.03), being non-specialist, (OR = 3.9, 95% CI: 2.08, 7.13), and being employed in the government sector only (OR = 2.0; 95% CI: 1.09, 3.82). The high-turnover intention among Iraqi doctors is significantly associated with working and security conditions. An urgent and effective strategy is required to prevent doctors' exodus.

Objective. To explore for the first time the extent to which Iraqi pharmacy students and faculty use Facebook and university email for academic communications, and to examine factors influencing utilization within the framework of the Technology Acceptance Model (TAM). Methods. An electronic survey was administered to convenience samples of students and faculty of six Iraqi public schools and colleges of pharmacy in 2015. Results. Responses included 489 student and 128 faculty usable surveys. Both students and faculty use Facebook more than university email for academic communications. Less than a third of the faculty used university email. Students used Facebook for academic purposes twice as much as faculty. Conclusion. Absence of university email in Iraqi schools and colleges of pharmacy makes Facebook essential for faculty-student communications. The majority (71.1% to 82%) of respondents perceived that Facebook was easy to use. Three TAM variables (intention to use, attitude toward use and perceived usefulness) had significant positive associations with actual use of both Facebook messaging and university email.

Salman, Khlood F; Resick, Lenore K

2015-08-01

The purpose of this study was to understand the description of health among Iraqi women refugees, their health status, and health experiences during resettlement in the United States. Twelve women, ages 21-67 years old, who resettled in the United States during or after 2003 where interviewed. The women described health as a gift determined by God, the ability to function, the absence of physical symptoms, and the need to feel safe and secure in the context of resettlement. Although the Iraqi women valued health, during the resettlement process, seeking safety and feeling secure were the foremost priorities. Findings revealed that this is a vulnerable population which has experienced the violence of war and, as a result, have unique physical, mental, economic, and social concerns related to health. Implications are for a multidisciplinary approach to best meet the unique individual health needs of this vulnerable population.

Arresting relaxation in Pickering Emulsions

Science.gov (United States)

Atherton, Tim; Burke, Chris

2015-03-01

Pickering emulsions consist of droplets of one fluid dispersed in a host fluid and stabilized by colloidal particles absorbed at the fluid-fluid interface. Everyday materials such as crude oil and food products like salad dressing are examples of these materials. Particles can stabilize non spherical droplet shapes in these emulsions through the following sequence: first, an isolated droplet is deformed, e.g. by an electric field, increasing the surface area above the equilibrium value; additional particles are then adsorbed to the interface reducing the surface tension. The droplet is then allowed to relax toward a sphere. If more particles were adsorbed than can be accommodated by the surface area of the spherical ground state, relaxation of the droplet is arrested at some non-spherical shape. Because the energetic cost of removing adsorbed colloids exceeds the interfacial driving force, these configurations can remain stable over long timescales. In this presentation, we present a computational study of the ordering present in anisotropic droplets produced through the mechanism of arrested relaxation and discuss the interplay between the geometry of the droplet, the dynamical process that produced it, and the structure of the defects observed.

The burden of neuropsychiatric disorders in refugees is likely high, but little has been reported on the neuropsychiatric disorders that affect Syrian and Iraqi refugees in a country of first asylum. This analysis aimed to study the cost and burden of neuropsychiatric disorders among refugees from Syria and Iraq requiring exceptional, United Nations-funded care in a country of first asylum. The United Nations High Commissioner for Refugees works with multi-disciplinary, in-country exceptional care committees to review refugees' applications for emergency or exceptional medical care. Neuropsychiatric diagnoses among refugee applicants were identified through a retrospective review of applications to the Jordanian Exceptional Care Committee (2012-2013). Diagnoses were made using International Classification of Disease-10(th) edition codes rendered by treating physicians. Neuropsychiatric applications accounted for 11% (264/2526) of all Exceptional Care Committee applications, representing 223 refugees (40% female; median age 35 years; 57% Syrian, 36% Iraqi, 7% other countries of origin). Two-thirds of neuropsychiatric cases were for emergency care. The total amount requested for neuropsychiatric disorders was 925,674 USD. Syrian refugees were significantly more likely to request neurotrauma care than Iraqis (18/128 vs. 3/80, p = 0.03). The most expensive care per person was for brain tumor (7,905 USD), multiple sclerosis (7,502 USD), and nervous system trauma (6,466 USD), although stroke was the most frequent diagnosis. Schizophrenia was the most costly and frequent diagnosis among the psychiatric disorders (2,269 USD per person, 27,226 USD total). Neuropsychiatric disorders, including those traditionally considered outside the purview of refugee health, are an important burden to health among Iraqi and Syrian refugees. Possible interventions could include stroke risk factor reduction and targeted medication donations for multiple sclerosis, epilepsy, and

The aim of the present paper was to describe food and nutrient intake among 12-month-old Norwegian-Somali and Norwegian-Iraqi infants, with a focus on iron and vitamin D intake. A cross-sectional survey was conducted from August 2013 through September 2014. Eighty-nine mothers/infants of Somali origin and 77 mothers/infants of Iraqi origin residing in Eastern Norway participated in the study. Data were collected using two 24-h multiple-pass recalls. Forty percent of the Norwegian-Somali infants and 47% of the Norwegian-Iraqi infants were breastfed at 12 months of age ( p = 0.414). Median energy percentages (E%) from protein, fat and carbohydrates were within the recommended intake ranges, except the level of saturated fats (12-13 E%). Median intakes of almost all micronutrients were above the recommended daily intakes. Most of the infants consumed iron-enriched products (81%) and received vitamin D supplements (84%). The median intakes of iron and vitamin D were significantly higher among infants receiving iron-enriched products and vitamin D supplements compared to infants not receiving such products ( p food and nutrient intake of this group of infants in general seems to be in accordance with Norwegian dietary recommendations. Foods rich in iron and vitamin D supplements were important sources of the infants' intake of iron and vitamin D and should continue to be promoted.

However, the unusual circumstances that happened in Iraq were affected on a universities course. The revolution in information technology (IT affects most of our activations. As a result, it is important to consider the impact of IT on accounting careers. Developing accenting information system course content can generate an accountant who is armed with the knowledge and skills before entering accounting job. Also the development process required instructors have characteristics that make the integrating process of IT knowledge components in AIS course content more smoothly. Iraq is the country facing many difficulties that makes its higher education institutions (HEIs suffered from un updated learning environment and technological backwardness. This causes a low level of accounting graduates’ knowledge and in turn leads to led to consider the Iraqi accountant incapable of working with international organizations and companies or conducting was it professionally. The aim of this paper is to explain the role of IT knowledge elements in developing AIS course content in Iraqi HEIs with considering the moderate effect of the instructors’ characteristics. Furthermore, this paper discusses the development and validation of the quantitative instrument (questionnaire for IT knowledge elements in Iraqi HEIs. Moreover, the reliability of the constructs is also discussed.

2011-11-01

Full Text Available The authors report a case of cardiac arrest in a patient receiving intravenous (IV metoclopramide and review the pertinent literature. A 62-year-old morbidly obese female admitted for a gastric sleeve procedure, developed cardiac arrest within one minute of receiving metoclopramide 10 mg via slow intravenous (IV injection. Bradycardia at 4 beats/min immediately appeared, progressing rapidly to asystole. Chest compressions restored vital function. Electrocardiogram (ECG revealed ST depression indicative of myocardial injury. Following intubation, the patient was transferred to the intensive care unit. Various cardiac dysrrhythmias including supraventricular tachycardia (SVT associated with hypertension and atrial fibrillation occurred. Following IV esmolol and metoprolol, the patient reverted to normal sinus rhythm. Repeat ECGs revealed ST depression resolution without pre-admission changes. Metoclopramide is a non-specific dopamine receptor antagonist. Seven cases of cardiac arrest and one of sinus arrest with metoclopramide were found in the literature. The metoclopramide prescribing information does not list precautions or adverse drug reactions (ADRs related to cardiac arrest. The reaction is not dose related but may relate to the IV administration route. Coronary artery disease was the sole risk factor identified. According to Naranjo, the association was possible. Other reports of cardiac arrest, severe bradycardia, and SVT were reviewed. In one case, five separate IV doses of 10 mg metoclopramide were immediately followed by asystole repeatedly. The mechanism(s underlying metoclopramide’s cardiac arrest-inducing effects is unknown. Structural similarities to procainamide may play a role. In view of eight previous cases of cardiac arrest from metoclopramide having been reported, further elucidation of this ADR and patient monitoring is needed. Our report should alert clinicians to monitor patients and remain diligent in surveillance and

The Iraq conflict resulted in the largest displacement in the Middle East since the Palestinian crisis, and provision of health services to the displaced population presents a critical challenge. The study aimed to provide information on chronic medical conditions and disability to inform humanitarian assistance planning. Nationally representative cross-sectional surveys of Iraqi populations displaced in Jordan and Syria were conducted in late 2008 and early 2009. Clusters of 10 household were randomly selected using probability-based sampling; a total of 1200 and 813 Iraqi households in Jordan and Syria, respectively, were interviewed. The majority of respondents in both countries perceived healthcare as unaffordable but accessible; cost was an important barrier to care. In Jordan, most routine health expenditures were for medications where in Syria, expenses were divided between medical consultations and medication. Chronic disease prevalence among adults was 51.5% (confidence interval (CI): 49.4-53.5) in Syria and 41.0% (CI: 39.4-42.7) in Jordan, most common were hypertension and musculoskeletal problems. Overall disability rates were 7.1% (CI: 6.3-8.0) in Syria and 3.4% (CI: 3.0-3.9) in Jordan. In both countries, the majority of disability was attributed to conflict, prevalence was higher in men than women, and depression was the leading cause of mental health disability. Chronic illnesses, disabilities and psychological health are key challenges for the Iraqi population and the health systems in Jordan and Syria. Continued attention to the development of systems to manage conditions that require secondary and tertiary care is essential, particularly given reported difficulties in accessing care and the anticipated prolonged displacement.

Crack arrest within teeth at the dentinoenamel junction caused by elastic modulus mismatch.

Science.gov (United States)

Bechtle, Sabine; Fett, Theo; Rizzi, Gabriele; Habelitz, Stefan; Klocke, Arndt; Schneider, Gerold A

2010-05-01

Enamel and dentin compose the crowns of human teeth. They are joined at the dentinoenamel junction (DEJ) which is a very strong and well-bonded interface unlikely to fail within healthy teeth despite the formation of multiple cracks within enamel during a lifetime of exposure to masticatory forces. These cracks commonly are arrested when reaching the DEJ. The phenomenon of crack arrest at the DEJ is described in many publications but there is little consensus on the underlying cause and mechanism. Explanations range from the DEJ having a larger toughness than both enamel and dentin up to the assumption that not the DEJ itself causes crack arrest but the so-called mantle dentin, a thin material layer close to the DEJ that is somewhat softer than the bulk dentin. In this study we conducted 3-point bending experiments with bending bars consisting of the DEJ and surrounding enamel and dentin to investigate crack propagation and arrest within the DEJ region. Calculated stress intensities around crack tips were found to be highly influenced by the elastic modulus mismatch between enamel and dentin and hence, the phenomenon of crack arrest at the DEJ could be explained accordingly via this elastic modulus mismatch.

The Heavy-Section Steel Technology (HSST) Program at the Oak Ridge National Laboratory under the sponsorship of the Nuclear Regulatory Commission is conducting analytical and experimental studies aimed at understanding the circumstances that would initiate the growth of an existing crack in a reactor pressure vessel (RPV) and the conditions leading to arrest of a propagating crack. Objectives of these studies are to determine (1) if the material will exhibit crack-arrest behavior when the driving force on a crack exceeds the ASME limit, (2) the relationship between K Ia and temperature, and (3) the interaction of fracture modes (arrest, stable crack growth, unstable crack growth, and tensile instability) when arrest occurs at high temperatures. In meeting these objectives, crack-arrest data are being developed over an expanded temperature range through tests involving large thermally shocked cylinders, pressurized thermally shocked vessels, and wide-plate specimens. The wide-plate specimens provide the opportunity for a significant number of data points to be obtained at relatively affordable costs. These tests are designed to provide fracture-toughness measurements approaching or above the onset of the Charpy upper-shelf regime in a rising toughness region and with an increasing driving force. This document discusses test methodology and results. 23 refs., 92 figs., 25 tabs

"Seeing the Life": Redefining self-worth and family roles among Iraqi refugee families resettled in the United States.

Nelson, Matthew; Hess, Julia Meredith; Isakson, Brian; Goodkind, Jessica

2016-08-01

Social and geographic displacement is a global phenomenon that precipitates novel stressors and disruptions that intersect with longstanding familial and social roles. Among the displaced are war-torn Iraqi refugee families, who must address these new obstacles in unconventional ways. This study explores how such disruptions have influenced associations between gender and apparent self-worth experienced by Iraqi refugee families upon relocation to the United States. Further, the psychosocial mechanisms requisite of any novel approach to a new social construct are explored and reveal that production in the family is at the core of instability and shifting power dynamics during resettlement, preventing family members from "seeing the life" in the United States that they had envisioned prior to immigration. Over 200 semi-structured qualitative interviews with Iraqi participants and mental health providers were conducted over the course of the study, and demonstrate a plasticity among social roles in the family and community that transcends the notion of a simple role reversal, and illustrate the complex positionalities that families under stress must approximate during such physical and social displacement.

The high prevalence of female genital mutilation has been a concern in Iraqi Kurdistan. This study was undertaken to estimate its prevalence and describe factors associated with its occurrence. A cross-sectional survey was undertaken from March to April 2011 of females aged up to 20 years using interviews and clinical examination. The survey included 1,508 participants with mean age of 13.5 years (SD 5.6). Overall female genital mutilation prevalence was 23%, and the mean age at which it had been performed was 4.6 years (SD 2.4). Type I (partial or total removal of the clitoris) comprised 76% of those who had had female genital mutilation; in 79% of cases the decision to perform it was made by the mother; and in 54% of cases it was performed by traditional birth attendants/midwives. Women aged 16 years and over were more likely to have had female genital mutilation compared to children aged below 6 years (OR 11.9, p Kurdistan region were more likely to have been circumcised. The study results show that female genital mutilation is a frequent practice in Iraqi Kurdistan. Attention and intervention is needed to address this aspect of the well-being of girls and women.

This study was carried out in 4 Iraqi South-central governorates using 596 pre-mating and 628 pregnant buffaloes (during the last two months of gestation. Pre-mating buffaloes were divided randomly into 496 concentrate-supplemented buffaloes (Flushing and 100 control ones. Additionally, pregnant buffaloes were also divided into 528 concentrate- supplemented buffaloes (Steaming up and 100 controls. Each buffalo within the flushing and steaming up groups were fed daily on 7 Kg of concentrate diet (13% crude protein and 1.70 Mcal of net energy for 60 days. The control buffaloes were nourished only on low-quality roughages of the area and wheat bran. Higher estrus (+15%, P<0.01, pregnancy (+23.8%, P<0.05 and calving rates (+30.8%, P<0.01 were observed in concentrate-supplemented buffaloes as compared with controls. An obvious increase in (P<0.05 calving rate (+14.7%, daily milk yield (+44.8% and calf birth weight (+25.6% were noted in steaming up buffaloes in comparison with control buffaloes. Results indicated that improvement in feeding schedule of Iraqi buffaloes during pre-mating and late gestation periods enhanced the reproductive performance and increased milk production of subsequent lactation and calf birth weight. These improvements increased owner income ($174=209,000 Iraqi dinar /buffalo from the sale of meat and milk.

Unraveling this relationship is potentially important for better understanding of breast cancer etiology, early detection and possibly prevention of breast cancer. The aim of the current study is to unravel the association between EBV and primary invasive breast cancer (PIBC) in two different Arab populations (Egyptian and Iraqi women). Patients and Methods: The study was done on paraffin-embedded tissues of 40 Egyptian and 50 Iraqi patients with PIBC in addition to 20 normal breast tissues as controls for each group. Both controls and neoplastic tissues were assessed for the expression of EBV genes and proteins (EBNA-1, LMP-1, and EBER) as well as CD21 marker by immunohistochemistry (IHC), in situ hybridization (ISH) and PCR techniques. Results: Our gold standard for EBV reactivity in breast cancer cases was positivity of both EBNA1 by PCR and EBER by in situ hybridization. EBV was detected in 18/40 (45%) and 14/50 (28%) of Egyptian and Iraqi women; respectively where p = 0.073, compared to 0/20 (0%) of their control groups (p < 0.05). Regarding the association between EBV positivity and tumor grade, there was not any statistical significant difference between EBV presence and tumor grade in both populations

Measles virus C protein suppresses gamma-activated factor formation and virus-induced cell growth arrest

International Nuclear Information System (INIS)

Yokota, Shin-ichi; Okabayashi, Tamaki; Fujii, Nobuhiro

2011-01-01

Measles virus (MeV) produces two accessory proteins, V and C, from the P gene. These accessory proteins have been reported to contribute to efficient virus proliferation through the modulation of host cell events. Our previous paper described that Vero cell-adapted strains of MeV led host cells to growth arrest through the upregulation of interferon regulatory factor 1 (IRF-1), and wild strains did not. In the present study, we found that C protein expression levels varied among MeV strains in infected SiHa cells. C protein levels were inversely correlated with IRF-1 expression levels and with cell growth arrest. Forced expression of C protein released cells from growth arrest. C-deficient recombinant virus efficiently upregulated IRF-1 and caused growth arrest more efficiently than the wild-type virus. C protein preferentially bound to phosphorylated STAT1 and suppressed STAT1 dimer formation. We conclude that MeV C protein suppresses IFN-γ signaling pathway via inhibition of phosphorylated STAT1 dimerization.

Refugees have typically experienced stress and trauma before entering the US. Stressors and mental health disorders may contribute to obesity. The aim of this study was to investigate changes in the body mass index (BMI) in Iraqi refugees settled in Michigan in relationship to pre- and post-migration stressors and mental health. Anthropometric and demographic data were collected from 290 Iraqi refugees immediately after they arrived in Michigan and one year after settlement. Significant increases were observed in BMI (+0.46 ± 0.09 kg/m(2), p refugees suffering from hypertension (from 9.6 to 13.1%, p migration trauma and social support, were also observed. Linear regression analyses failed to link stressors, well-being, and mental health to changes in BMI. It is likely that acculturation to a new lifestyle, including dietary patterns and physical activity levels, may have contributed to these changes.

Nelson, Matthew; Hess, Julia Meredith; Isakson, Brian; Goodkind, Jessica

2017-01-01

Social and geographic displacement is a global phenomenon that precipitates novel stressors and disruptions that intersect with longstanding familial and social roles. Among the displaced are war-torn Iraqi refugee families, who must address these new obstacles in unconventional ways. This study explores how such disruptions have influenced associations between gender and apparent self-worth experienced by Iraqi refugee families upon relocation to the United States. Further, the psychosocial mechanisms requisite of any novel approach to a new social construct are explored and reveal that production in the family is at the core of instability and shifting power dynamics during resettlement, preventing family members from “seeing the life” in the United States that they had envisioned prior to immigration. Over 200 semi-structured qualitative interviews with Iraqi participants and mental health providers were conducted over the course of the study, and demonstrate a plasticity among social roles in the family and community that transcends the notion of a simple role reversal, and illustrate the complex positionalities that families under stress must approximate during such physical and social displacement.

The understanding and detection of molar-incisor hypomineralisation (MIH) is linked to its recognition by clinicians. No study has investigated dental clinicians' level of perception regarding MIH in the Middle East region including Iraq. To determine the perception of Iraqi academic clinicians about MIH prevalence, severity and aetiological factors. A questionnaire, based on previous European and Australian/New Zealand studies was administered to the academic dental staff of Mosul University. A response rate of 77.7% was reported. General dental practitioners represented 30.8% of the total respondents, whilst 65.1% were dentists with post-graduate qualification. The majority of the respondents (81.2%) encountered MIH in their clinical activities and 37.3% of them identified that the prevalence appeared to have increased in recent years. Fewer than half of the respondents observed MIH affected teeth on a monthly basis. The condition was less commonly seen in primary second molars than the first permanent molars. A variation in views was recorded about MIH specific aetiological factor/s. Respondents advocated the need for clinical training regarding MIH-aetiological and therapeutic fields. Molar-incisor hypomineralisation is a condition commonly diagnosed by Iraqi dental academics. No apparent consensus existed between the general and specialist dentists regarding the anticipated prevalence, severity and aetiology of this condition. © 2011 The Authors.

Arab countries face the corruption issues in its several public organizations. The corruption in these countries is considered as the main challenge. The oil sector is one of the public sectors that have huge level of corruption. However, the Iraqi economy had become dependable on oil sector daring the last three decades, and on the contrary, of what other oil countries did. The capital is considered as one of the essential factor for economic development. The revenues of oil exports will stay the essential source for economic development in Iraq in the future in order to reduce being dependable on oil. Since the beginning of the 3rd thousands, the world witnessed great rise in the demand on oil, but the Iraqi exports of crude oil come to be less than its similarities in the seventeenths of last century. So our oil sector is still in need of deep study. This study focuses on technological technique that can make huge decrease for corruption in oil sector in Iraq. However, e-government is considered as the best techniques that can decrease the corruption. Thus, this study bases on challenges that effect on build successful e-government project in Iraqi oil industry.

2004-05-01

This study correlated the effect of witnessing a cardiac arrest and instituting bystander CPR (ByCPR), as a secondary end point in a study evaluating the effect of bicarbonate on survival. This prospective, randomised, double blinded clinical intervention trial enrolled 874 prehospital cardiopulmonary arrest patients encountered in a prehospital urban, suburban, and rural regional emergency medical service (EMS) area. This group underwent conventional advanced cardiac life support intervention followed by empiric early administration of sodium bicarbonate (1 mEq/l), monitoring conventional resuscitation parameters. Survival was measured as presence of vital signs on emergency department (ED) arrival. Data were analysed using chi(2) with Pearson correlation and odds ratio where appropriate. The overall survival rate was 13.9% (110 of 792) of prehospital cardiac arrest patients. The mean (SD) time until provision of bystander cardiopulmonary resuscitation (ByCPR) by laymen was 2.08 (2.77) minutes, and basic life support (BLS) by emergency medical technicians was 6.62 (5.73) minutes. There was improved survival noted with witnessed cardiac arrest-a 2.2-fold increase in survival, 18.9% (76 of 402) versus 8.6% (27 of 315) compared with unwitnessed arrests (ptwo minutes (p = 0.3752). Survival after prehospital cardiac arrest is more likely when witnessed, but not necessarily when ByCPR was performed by laymen.

Abstract Objective To determine the range and burden of health services utilization among Iraqi refugees receiving health assistance in Jordan, a country of first asylum. Methods Medical conditions, diagnosed in accordance with the tenth revision of the International classification of diseases, were actively monitored from 1January to 31December 2010 using a pilot centralized database in Jordan called the Refugee Assistance Information System. Findings There were 27 166 medical visits by 7642 Iraqi refugees (mean age: 37.4 years; 49% male; 70% from Baghdad; 6% disabled; 3% with a history of torture). Chronic diseases were common, including essential hypertension (22% of refugees), visual disturbances (12%), joint disorders (11%) and type II diabetes mellitus (11%). The most common reasons for seeking acute care were upper respiratory tract infection (11%), supervision of normal pregnancy (4%) and urinary disorders (3%). The conditions requiring the highest number of visits per refugee were cerebrovascular disease (1.46 visits), senile cataract (1.46) and glaucoma (1.44). Sponsored care included 31 747 referrals or consultations to a specialty service, 18 432 drug dispensations, 2307 laboratory studies and 1090 X-rays. The specialties most commonly required were ophthalmology, dentistry, gynaecology and orthopaedic surgery. Conclusion Iraqi refugees in countries of first asylum and resettlement require targeted health services, health education and sustainable prevention and control strategies for predominantly chronic diseases.

Refugees are one of the most vulnerable groups in Australian society, presenting high levels of exposure to traumatic events and consequently high levels of severe psychological distress. While there is a need for professional help, only a small percentage will receive appropriate care for their mental health concerns. This study aimed to determine cultural considerations required when providing mental health first aid to Iraqi refugees experiencing mental health problems or crises. Using a Delphi method, 16 experts were presented with statements about possible culturally-appropriate first aid actions via questionnaires and were encouraged to suggest additional actions not covered by the questionnaire content. Statements were accepted for inclusion in a guideline if they were endorsed by ≥90 % of panellists as 'Essential' or 'Important'. From a total of 65 statements, 38 were endorsed (17 for cultural awareness, 12 for cross-cultural communication, 7 for stigma associated with mental health problems, and 2 for barriers to seeking professional help). Experts were able to reach consensus about how to provide culturally-appropriate first aid for mental health problems to Iraqi refugees, demonstrating the suitability of this methodology in developing cultural considerations guidelines. This specific refugee study provided potentially valuable cultural knowledge required to better equip members of the Australian public on how to respond to and assist Iraqi refugees experiencing mental health problems or crises.

The Stalled Recovery of the Iraqi Marshes

Directory of Open Access Journals (Sweden)

Richard H. Becker

2014-01-01

Full Text Available The Iraqi (Mesopotamian Marshes, an extensive wetlands system in Iraq, has been heavily impacted by both human and climate forces over the past decades. In the period leading up to the Second Gulf War in 2002, the marshlands were shrinking due to both a policy of draining and water diversion in Iraq and construction of dams upstream on the Tigris and Euphrates rivers. Following the war through 2006, this trend was reversed as the diversions were removed and active draining stopped. A combination of MODIS and GRACE datasets were used to determine the change in surface water area (SWA in the marshes, marshland extent and change in mass both upriver in the Tigris and Euphrates watersheds and in the marshlands. Results suggest that the post war dam removal and decreased pumping in 2003 provided only temporary respite for the marshlands (2003–2006 SWA: 1,477 km2 increase (600%, water equivalent depth (WED: +2.0 cm/yr.; 2006–2009: −860 km2 (−41% WED: −3.9 cm/yr.. Unlike in the period 2003–2006, from 2006 forward the mass variations in the marshes are highly correlated with those in the upper and middle watershed (R = 0.86 and 0.92 respectively, suggesting that any recovery due to that removal is complete, and that all future changes are tied more strongly to any climate changes that will affect recharge in the upper Tigris-Euphrates system. Precipitation changes in the watershed show a reduction of an average of 15% below the 15 yr mean in 2007–2011 This corresponds with published ensemble predictions for the 2071–2099 time period, that suggested similar marshland shrinkage should be expected in that time period.

Berberine, a genotoxic alkaloid, induces ATM-Chk1 mediated G2 arrest in prostate cancer cells

Berberine has been shown to possess anti-tumor activity against a wide spectrum of cancer cells. It inhibits cancer cell proliferation by inducing cell cycle arrest, at G1 and/or G2/M, and apoptosis. While it has been documented that berberine induces G1 arrest by activating the p53-p21 cascade, it remains unclear what mechanism underlies the berberine-induced G2/M arrest, which is p53-independent. In this study, we tested the anti-proliferative effect of berberine on murine prostate cancer cell line RM-1 and characterized the underlying mechanisms. Berberine dose-dependently induced DNA double-strand breaks and apoptosis. At low concentrations, berberine was observed to induce G1 arrest, concomitant with the activation of p53-p21 cascade. Upon exposure to berberine at a higher concentration (50 μM) for 24 h, cells exhibited G2/M arrest. Pharmacological inhibition of ATM by KU55933, or Chk1 by UCN-01, could efficiently abrogate the G2/M arrest in berberine-treated cells. Downregulation of Chk1 by RNA interference also abolished the G2/M arrest caused by berberine, confirming the role of Chk1 in the pathway leading to G2/M arrest. Abrogation of G2/M arrest by ATM inhibition forced more cells to undergo apoptosis in response to berberine treatment. Chk1 inhibition by UCN-01, on the other hand, rendered cells more sensitive to berberine only when p53 was inhibited. Our results suggest that combined administration of berberine and caffeine, or other ATM inhibitor, may accelerate the killing of cancer cells.

Critical experiments, measurements, and analyses to establish a crack arrest methodology for nuclear pressure vessel steels

International Nuclear Information System (INIS)

Hahn, G.T.

1977-01-01

Substantial progress was made in three important areas: crack propagation and arrest theory, two-dimensional dynamic crack propagation analyses, and a laboratory test method for the material property data base. The major findings were as follows: Measurements of run-arrest events lent support to the dynamic, energy conservation theory of crack arrest. A two-dimensional, dynamic, finite-difference analysis, including inertia forces and thermal gradients, was developed. The analysis was successfully applied to run-arrest events in DCB (double-cantilever-beam) and SEN (single-edge notched) test pieces. A simplified procedure for measuring K/sub D/ and K/sub Im/ values with ordinary and duplex DCB specimens was demonstrated. The procedure employs a dynamic analysis of the crack length at arrest and requires no special instrumentation. The new method was applied to ''duplex'' specimens to measure the large K/sub D/ values displayed by A533B steel above the nil-ductility temperature. K/sub D/ crack velocity curves and K/sub Im/ values of two heats of A533B steel and the corresponding values for the plane strain fracture toughness associated with static initiation (K/sub Ic/), dynamic initiation (K/sub Id/), and the static stress intensity at crack arrest (K/sub Ia/) were measured. Possible relations among these toughness indices are identified. During the past year the principal investigators of the participating groups reached agreement on a crack arrest theory appropriate for the pressure vessel problem. 7 figures

The views of medical professionals on efficiency of health system and needs for any changes are very critical and constitute a cornerstone for any health system improvement. This is particularly relevant to Iraqi Kurdistan case as the events of the last few decades have significantly devastated the national Iraqi health system while the necessity for adopting a new health care system is increasingly recognized since 2004. This study aims to examine the regional health system in Iraqi Kurdistan from medical professionals' perspectives and try to define its problems and priorities for improvement. A survey questionnaire was developed and administered to a convenience sample of 250 medical professionals in Erbil governorate. The questionnaire included four items; rating of the quality of services and availability of resources in the health institutions, view on different aspects of the health system, the perceived priority needs for health system improvement and gender and professional characteristics of the respondents. The response rate to the survey was 83.6%. A high proportion of respondents rated the different aspects of services and resources in the health institutions as weak or very weak including the availability of the required quantity and quality of medicines (68.7%), the availability of sufficient medical equipment and investigation tools (68.7%), and the quality of offered services (65.3%). Around 72% of respondents had a rather negative view on the overall health system. The weak role of medical research, the weak role of professional associations in controlling the system and the inefficient health education were identified as important problems in the current health system (87.9%, 87.1% and 84.9%, respectively). The priority needs of health system improvement included adoption of social insurance for medical care of the poor (82%), enhancing the role of family medicine (77.2%), adopting health insurance system (76.1%) and periodic scientific

The study of the performance of radioactive lightning arrester comparing to the performance of conventional one are presented. Measurements of currents between lightning arrester and an energyzed plate with wind simulation were done for radioactive and conventional lightning arresters, separately. The attraction range of radioactive and conventional lightning arresters using atmospheric pulses produced by a generator of 3MV were verified, separately and simultaneously. The influence of ionization produced by radioactive lightning arrester on critical disruptive tension of a spark plate, testing two lightning arresters for differents nominal attraction distances with applications of atmospheric pulses (positive and negative polarity) and tensions of 60 Hz was verified. The radiation emitted by a radioactive lightning had used in a building was retired and handled without special carefullness by a personnel without worthy of credence to evaluate the hazard in handling radioactive lightning arrester was measured. Critical disruptive tensions of radioactive and conventional lightning arrester using a suspensed electrode and external pulse generator of 6MV was measured. The effect of attraction of a radioactive and conventional lightning arresters disposed symmetrically regarding the same suspensed electrode was verified simultaneously. Seven cases on faults of radioactive lightning arrester in external areas are present. (M.C.K.) [pt

The possibility of using gamma-irradiation for date preservation had been considered as an alternative method to fumigation. Two varieties of Iraqi dates (Zahdi and Sayer) had been used in the study, and three doses of 50, 100 and 150 krads. A combination of treatments of heat plus irradiation were also applied and tests were conducted at three maturation stages. Gas chromatographic analysis was used to fractionate sugars from dates after converting to their TMS - ether derivatives. No qualitative or quantitative changes were observed in sugar components in either Zahdi or Sayer dates within the doses used in the experiments.

Full Text Available The current study involved conducting a pilot test of a culturally sensitive support group program developed to assist Iraqi women in the year following the birth of their baby (CSSG-B in Perth, Western Australia. The aim of this study was to evaluate the social validity of the program. It was hypothesised that women involved in the program would find the program to be socially valid and culturally appropriate, and will also report lower levels of depressive symptomatology and higher levels of social support, following the group intervention. Participants were twelve Iraqi Arabic speaking women, who had a child less than 12 months of age. The program was based on Iraqi women's explanatory models (Kleinman, 1978; Di Ciano, Rooney, Wright, Hay, & Robinson, 2010 of the birth and motherhood experience. Social validity ratings were obtained during the implementation of the program in order to assess the level of acceptability of the intervention. A one-group pretest-posttest design was used to determine if depressive symptoms had decreased during the course of the intervention and social support had increased. Results indicated that Iraqi Arabic speaking women found the support group intervention acceptable and relevant and there was a significant decrease in scores on the Edinburgh Postnatal Depression scale from pretest to posttest. These results that the culturally sensitive group intervention was culturally acceptable and was associated with decreased levels of depressive symptomatology.

Objective was to establish the prevalence of dyslipidemia in the Iraqi adult population in Mosul, according to the different recommended criteria. The study was carried out from October 2003 to April 2004, with 871 apparently healthy volunteers (413 males, 458 females) aged 20-70 year ([mean+- SD] 41.2+-13.8 year). Fasting blood specimens were collected from all subjects for measurement of serum lipid profile including triglycerides (TG), total cholesterol (TC), high density lipoprotein-cholesterol (HDL-C), low density lipoprotein-cholesterol (LDL-C), and ratios of cholesterol such as TC:HDL-C, LDL-C:HDL-C, and TG:HDL-C. Classification was carried out according to the different cut-off levels as recommended by the 2001 American National Cholesterol Education Program (NCEP) III using thresholds of TG>150mg/dl (2.0 mmol/L), LDL-C>100 mg/dl (2.6 mmol/L), LDL-C 130mg/dl (3.37 mmol/L). The criteria of the 1998 British Hyperlipidemia Association (BHA) were also followed using thresholds of TG>180mg/dl (2.4mmol/L), TC>194mg/dl (5.0 mmol/L), LDL-C>116mg/dl (3.0mmol/L), HDL-C 5.0, HDL-C: DL-C>2.5 and TG: HDL-C>3.0. Based on the American NCEPIII criteria, the dyslipidemic states were noted with high TG (41.6%), high LDL-C (57.8%), low HDL-C (49.9%) and high HDL-C (57.8%), low HDL-C (49.9%) and high non-HDL-C (56.8%) from the subjects. Based on BHA criteria, high TG24.5%), high TC (32.7%), high HDL-C (37.8%), high TC: HDL-C (30.9%), high LDL-C HDL-C (55.7%) and high TG: HDL-C (58.3%) were noted. Dyslipidemia is common in Iraqi population, and this was identified at different recommendation criteria. (author)

Cardiac arrest attributable to anaesthesia occurs at the rate of between 0.5 and 1 case per 10 000 cases, tends to have a different profile to that of cardiac arrest occurring elsewhere, and has an in-hospital mortality of 20%. However, as individual practitioners encounter cardiac arrest rarely, the rapidity with which the diagnosis is made and the consistency of appropriate management varies considerably. To examine the role of a previously described core algorithm "COVER ABCD-A SWIFT CHECK", supplemented by a sub-algorithm for cardiac arrest, in the management of cardiac arrest occurring in association with anaesthesia. The potential performance of this structured approach for each the relevant incidents among the first 4000 reported to the Australian Incident Monitoring Study (AIMS) was compared with the actual management as reported by the anaesthetists involved. There were 129 reports of cardiac arrest associated with anaesthesia among the first 4000 AIMS incident reports. Identified aetiological factors were grouped into five categories: (1) anaesthetic technique (11 cases with this category alone; 32 with this and one or more of the other categories, representing 25% of all 129 cardiac arrests); (2) drug related (16; 32, 25%); (3) associated with surgical procedure (9; 29, 22%); (4) associated with pre-existing medical or surgical disease (30; 82, 64%); (5) unknown (8; 14, 11%). The "real life" presentation and management of cardiac arrest in association with anaesthesia differs substantially from that detailed in general published guidelines. Cardiac rhythms at the time were sinus bradycardia (23%); asystole (22%); tachycardia/ventricular tachycardia/ventricular fibrillation (14%); and normal (7%), with a further third unknown. Details of treatment were recorded in 110 reports; modalities employed included cardiac compression (72%); adrenaline (61%); 100% oxygen (58%); atropine (38%); intravenous fluids (25%), and electrical defibrillation (17%).

Extracorporeal membrane oxygenation for refractory cardiac arrest

Directory of Open Access Journals (Sweden)

Steven A Conrad

2017-01-01

Full Text Available Extracorporeal cardiopulmonary resuscitation (ECPR is the use of rapid deployment venoarterial (VA extracorporeal membrane oxygenation to support systemic circulation and vital organ perfusion in patients in refractory cardiac arrest not responding to conventional cardiopulmonary resuscitation (CPR. Although prospective controlled studies are lacking, observational studies suggest improved outcomes compared with conventional CPR when ECPR is instituted within 30-60 min following cardiac arrest. Adult and pediatric patients with witnessed in-hospital and out-of-hospital cardiac arrest and good quality CPR, failure of at least 15 min of conventional resuscitation, and a potentially reversible cause for arrest are candidates. Percutaneous cannulation where feasible is rapid and can be performed by nonsurgeons (emergency physicians, intensivists, cardiologists, and interventional radiologists. Modern extracorporeal systems are easy to prime and manage and are technically easy to manage with proper training and experience. ECPR can be deployed in the emergency department for out-of-hospital arrest or in various inpatient units for in-hospital arrest. ECPR should be considered for patients with refractory cardiac arrest in hospitals with an existing extracorporeal life support program, able to provide rapid deployment of support, and with resources to provide postresuscitation evaluation and management.

2007-07-01

Objective was to establish the prevalence of dyslipidemia in the Iraqi adult population in Mosul, according to the different recommended criteria. The study was carried out from October 2003 to April 2004, with 871 apparently healthy volunteers (413 males, 458 females) aged 20-70 year ([mean+- SD] 41.2+-13.8 year). Fasting blood specimens were collected from all subjects for measurement of serum lipid profile including triglycerides (TG), total cholesterol (TC), high density lipoprotein-cholesterol (HDL-C), low density lipoprotein-cholesterol (LDL-C), and ratios of cholesterol such as TC:HDL-C, LDL-C:HDL-C, and TG:HDL-C. Classification was carried out according to the different cut-off levels as recommended by the 2001 American National Cholesterol Education Program (NCEP) III using thresholds of TG>150mg/dl (2.0 mmol/L), LDL-C>100 mg/dl (2.6 mmol/L), LDL-C<40mg/dl (1.04mmol/L) and non-HDL-C>130mg/dl (3.37 mmol/L). The criteria of the 1998 British Hyperlipidemia Association (BHA) were also followed using thresholds of TG>180mg/dl (2.4mmol/L), TC>194mg/dl (5.0 mmol/L), LDL-C>116mg/dl (3.0mmol/L), HDL-C<45mg/dl (1.15mmol/L), TC: HDL-C>5.0, HDL-C: DL-C>2.5 and TG: HDL-C>3.0. Based on the American NCEPIII criteria, the dyslipidemic states were noted with high TG (41.6%), high LDL-C (57.8%), low HDL-C (49.9%) and high HDL-C (57.8%), low HDL-C (49.9%) and high non-HDL-C (56.8%) from the subjects. Based on BHA criteria, high TG24.5%), high TC (32.7%), high HDL-C (37.8%), high TC: HDL-C (30.9%), high LDL-C HDL-C (55.7%) and high TG: HDL-C (58.3%) were noted. Dyslipidemia is common in Iraqi population, and this was identified at different recommendation criteria. (author)

Full Text Available The present study focuses on determining whether automatic speech recognition (ASR technology is reliable for improving English pronunciation to Iraqi EFL students. Non-native learners of English are generally concerned about improving their pronunciation skills, and Iraqi students face difficulties in pronouncing English sounds that are not found in their native language (Arabic. This study is concerned with ASR and its effectiveness in overcoming this difficulty. The data were obtained from twenty participants randomly selected from first-year college students at Al-Turath University College from the Department of English in Baghdad-Iraq. The students had participated in a two month pronunciation instruction course using ASR Eyespeak software. At the end of the pronunciation instruction course using ASR Eyespeak software, the students completed a questionnaire to get their opinions about the usefulness of the ASR Eyespeak in improving their pronunciation. The findings of the study revealed that the students found ASR Eyespeak software very useful in improving their pronunciation and helping them realise their pronunciation mistakes. They also reported that learning pronunciation with ASR Eyespeak enjoyable.

Full Text Available Background: Many attempts were done to develop a method that actually reflects the sagittal jaw discrepancies without depending on cranial landmarks or dental occlusion. This study aimed to use one of these methods (dentoskeletal overjet for assessing the sagittal jaw relationships of Iraqi adult sample with different skeletal jaw relationship. Materials and method: The sample consisted of 90 digital true lateral cephalometric radiographs of Iraqi individuals with no previous orthodontic treatment. Cephalometric analysis of skeletal sagittal jaw relationship -ANB angle, beta angle and Wits appraisal- will perform for everyone to divide the sample into three groups (skeletal class I, II, III for which the dentoskeletal overjet will be measured. All cephalometric measurements will be done using AutoCAD. Results: Descriptive statistics of all variables with different skeletal jaw relationship showed that mean values of dentoskeletal overjet were (1.15, 3.91 and –2.01 mm for skeletal class I, class II and class III jaw relationship respectively. Accurate reproducibility of dentoskeletal overjet in assessment of jaw skeletal relationship showed that the lowest value was for assessment of skeletal class III jaw relationship (73% and the value for assessment of both skeletal class I and class II was higher (93%. Conclusions: Dentoskeletal overjet could be utilized in accurate representation of skeletal jaw relationship.

Full Text Available Background: Smoking is a major public health problem, especially in Iraq. There is very little information had been documented regarding smoking risk factors and quit intention among Iraqi smokers. Objectives: The main objectives of this study are to determine smokers' knowledge and perception about smoking health risks; and to determine smoking behavior and quitting intentions among Iraqi smokers; as well as to predict the factors that may associate with quit intentions. Methods: A cross-sectional study was conducted at the outpatient clinic in Tikrit Teaching Hospital, Tikrit City, Iraq. Adult smokers who are smoking cigarette everyday and able to communicate with the researcher were invited to participate in the study. A self-administered questionnaire was used to collect data from 386 participants. Results: This study showed that smokers had low awareness about some risk effects of smoking such as lung cancer in nonsmokers (30.1%, impotence in male smokers (52.6%, premature ageing (64%, and stroke (66.3%. In addition, the high score of knowledge and perception was significantly associated with quitting intention. Conclusion: Smokers' knowledge and perception regarding smoking health effects were low, especially in terms of secondhand smokers. Many efforts needed from health policy-makers and health care professionals to disseminate information about the risks of smoking and health benefits of give up smoking.

The incidence of sudden cardiac arrest during participation in sports activities remains unknown. Preparticipation screening programs aimed at preventing sudden cardiac arrest during sports activities are thought to be able to identify at-risk athletes; however, the efficacy of these programs remains controversial. We sought to identify all sudden cardiac arrests that occurred during participation in sports activities within a specific region of Canada and to determine their causes. In this retrospective study, we used the Rescu Epistry cardiac arrest database (which contains records of every cardiac arrest attended by paramedics in the network region) to identify all out-of-hospital cardiac arrests that occurred from 2009 through 2014 in persons 12 to 45 years of age during participation in a sport. Cases were adjudicated as sudden cardiac arrest (i.e., having a cardiac cause) or as an event resulting from a noncardiac cause, on the basis of records from multiple sources, including ambulance call reports, autopsy reports, in-hospital data, and records of direct interviews with patients or family members. Over the course of 18.5 million person-years of observation, 74 sudden cardiac arrests occurred during participation in a sport; of these, 16 occurred during competitive sports and 58 occurred during noncompetitive sports. The incidence of sudden cardiac arrest during competitive sports was 0.76 cases per 100,000 athlete-years, with 43.8% of the athletes surviving until they were discharged from the hospital. Among the competitive athletes, two deaths were attributed to hypertrophic cardiomyopathy and none to arrhythmogenic right ventricular cardiomyopathy. Three cases of sudden cardiac arrest that occurred during participation in competitive sports were determined to have been potentially identifiable if the athletes had undergone preparticipation screening. In our study involving persons who had out-of-hospital cardiac arrest, the incidence of sudden cardiac

Arrested larval development in cattle nematodes.

Science.gov (United States)

Armour, J; Duncan, M

1987-06-01

Most economically important cattle nematodes are able to arrest their larval development within the host - entering a period of dormancy or hypobiosis. Arrested larvae have a low death rate, and large numbers can accumulate in infected cattle during the grazing season. Because of this, outbreaks of disease caused by such nematodes can occur at times when recent infection with the parasites could not have occurred, for example during winter in temperature northern climates when cattle are normally housed. The capacity to arrest is a heritable trait. It is seen as an adaptation by the parasite to avoid further development to its free-living stages during times when the climate is unsuitable for free-living survival. But levels of arrestment can vary markedly in different regions, in different cattle, and under different management regimes. Climatic factors, previous conditioning, host immune status, and farm management all seem to affect arrestment levels. In this article, James Armour and Mary Duncan review the biological basis of the phenomenon, and discuss the apparently conflicting views on how it is controlled.

Crack arrest and crack arrest toughness are of great interest, particularly for studies pertaining to safety of nuclear reactor pressure vessels. Investigations are needed in which the instantaneous values of stress intensity factor (K) can be observed during crack propagation and arrest. Such observations are possible if the test specimens are made from plates of a transparent photoelastic sensitive material. Values of K as a function of crack speed are shown for Homalite 100 and various epoxy blends. 9 figures

This study describes the epidemiology of sudden cardiac arrest patients in Victoria, Australia, as captured via the Victorian Ambulance Cardiac Arrest Register (VACAR). We used the VACAR data to construct a new model of out-of-hospital cardiac arrest (OHCA), which was specified in accordance with observed trends. All cases of cardiac arrest in Victoria that were attended by Victorian ambulance services during the period of 2002-2005. Overall survival to hospital discharge was 3.8% among 18,827 cases of OHCA. Survival was 15.7% among 1726 bystander witnessed, adult cardiac arrests of presumed cardiac aetiology, presenting in ventricular fibrillation or ventricular tachycardia (VF/VT), where resuscitation was attempted. In multivariate logistic regression analysis, bystander CPR, cardiac arrest (CA) location, response time, age and sex were predictors of VF/VT, which, in turn, was a strong predictor of survival. The same factors that affected VF/VT made an additional contribution to survival. However, for bystander CPR, CA location and response time this additional contribution was limited to VF/VT patients only. There was no detectable association between survival and age younger than 60 years or response time over 15min. The new model accounts for relationships among predictors of survival. These relationships indicate that interventions such as reduced response times and bystander CPR act in multiple ways to improve survival.

Regionalizing Immigration, Health and Inequality: Iraqi Refugees in Australia

Lenore Manderson

2012-01-01

Full Text Available Humanitarian immigrants and refugees face multiple adjustment tasks and post-settlement support services concentrated in metropolitan areas play an important role. As part of an ongoing commitment, the Australian Government has increasingly supported resettlement in rural and regional areas of the country. Drawing on the experience of Iraqi migrants in Victoria, Australia, we examine some of the conditions that characterize regional resettlement and raise key questions for public health policy. Structural vulnerabilities and discriminations impact upon physical, mental and social wellbeing, leading to further exclusion, with negative long-term implications. The discussion throws light on the issues that migrants and refugees may encounter in other parts within Australia, but are also germane in many countries and highlight the resulting complexity for policy-making.

Recent clinical studies reporting the high frequency of inadequate chest compression depth (compression depth in certain patients. Using a specially designed monitor/defibrillator equipped with a sternal pad fitted with an accelerometer and a pressure sensor, compression force and depth was measured during CPR in 91 adult out-of-hospital cardiac arrest patients. There was a strong non-linear relationship between the force of compression and depth achieved. Mean applied force for all patients was 30.3+/-8.2 kg and mean absolute compression depth 42+/-8 mm. For 87 of 91 patients 38 mm compression depth was obtained with less than 50 kg. Stiffer chests were compressed more forcefully than softer chests (pcompressed more deeply than stiffer chests (p=0.001). The force needed to reach 38 mm compression depth (F38) and mean compression force were higher for males than for females: 29.8+/-14.5 kg versus 22.5+/-10.2 kg (pcompression depth with age, but a significant 1.5 kg mean decrease in applied force for each 10 years increase in age (pcompressions performed. Average residual force during decompression was 1.7+/-1.0 kg, corresponding to an average residual depth of 3+/-2 mm. In most out-of-hospital cardiac arrest victims adequate chest compression depth can be achieved by a force<50 kg, indicating that an average sized and fit rescuer should be able to perform effective CPR in most adult patients.

2017-03-01

Patients with burns have to live with a variety of long-term physical and psychosocial consequences. Burns lead to prolonged hospital stay, disfiguring scars, disability, and even death. Since self-immolation is common in women of Iraqi Kurdistan, the present study sought to explore the experiences of women living with scars caused by self-immolation. This paper was part of a qualitative research study. A purposive sample of 18 female self-immolation survivors from Iraqi Kurdistan was selected, and 21 individual interviews were conducted and analyzed using conventional content analysis. Four categories emerged during the data analysis: (1) feelings of disbelief, regret, and anger caused by post-burn scars; (2) desperately seeking solutions; (3) grief due to disappointment and surrender to despair; and (4) rejection and isolation. In conclusion, individuals with scars and disfigurements sometimes adopted inappropriate measures to deal with the psychological problems caused by others' behaviors and wrong perceptions. Educational and support programs are hence indicated to promote awareness levels of self-immolation survivors, their families, and the whole society. Copyright © 2016 Elsevier Ltd and ISBI.

Cardiac arrest is a condition frequently encountered by physicians in the hospital setting including the Emergency Department, Intensive Care Unit and medical/surgical wards. This paper reviews the current literature involving the use of ultrasound in resuscitation and proposes an algorithmic approach for the use of ultrasound during cardiac arrest. At present there is the need for a means of differentiating between various causes of cardiac arrest, which are not a direct result of a primary ventricular arrhythmia. Identifying the cause of pulseless electrical activity or asystole is important as the underlying cause is what guides management in such cases. This approach, incorporating ultrasound to manage cardiac arrest aids in the diagnosis of the most common and easily reversible causes of cardiac arrest not caused by primary ventricular arrhythmia, namely; severe hypovolemia, tension pneumothorax, cardiac tamponade, and massive pulmonary embolus. These four conditions are addressed in this paper using four accepted emergency ultrasound applications to be performed during resuscitation of a cardiac arrest patient with the aim of determining the underlying cause of a cardiac arrest. Identifying the underlying cause of cardiac arrest represents the one of the greatest challenges of managing patients with asystole or PEA and accurate determination has the potential to improve management by guiding therapeutic decisions. We include several clinical images demonstrating examples of cardiac tamponade, massive pulmonary embolus, and severe hypovolemia secondary to abdominal aortic aneurysm. In conclusion, this protocol has the potential to reduce the time required to determine the etiology of a cardiac arrest and thus decrease the time between arrest and appropriate therapy.

He immediately received basic life support from a bystander and was transported to our hospital. On arrival, his spontaneous circulation had returned from a state of ventricular fibrillation and pulseless electrical activity. Following admission, hyperthyroidism led to a suspicion of thyroid storm, which was then diagnosed as a possible cause of the cardiac arrest. Although hyperthyroidism-induced cardiac arrest including ventricular fibrillation is rare, it should be considered when diagnosing the cause of treatable cardiac arrest.Keywords: hyperthyroidism, ventricular fibrillation, treatable cardiac arrest, cardiac arrest, cardiopulmonary arrest

Performance of Surge Arrester Installation to Enhance Protection

Directory of Open Access Journals (Sweden)

2017-01-01

Full Text Available The effects of abnormal voltages on power system equipment and appliances in the home have raise concern as most of the equipments are very expensive. Each piece of electrical equipment in an electrical system needs to be protected from surges. To prevent damage to electrical equipment, surge protection considerations are paramount to a well designed electrical system. Lightning discharges are able to damage electric and electronic devices that usually have a low protection level and these are influenced by current or voltage pulses with a relatively low energy, which are induced by lightning currents. This calls for proper designed and configuration of surge arresters for protection on the particular appliances. A more efficient non-linear surge arrester, metal oxide varistor (MOV, should be introduced to handle these surges. This paper shows the selection of arresters laying more emphasis on the arresters for residential areas. In addition, application and installation of the arrester will be determined by the selected arrester. This paper selects the lowest rated surge arrester as it provides insulation when the system is under stress. It also selected station class and distribution class of arresters as they act as an open circuit under normal system operation and to bring the system back to its normal operation mode as the transient voltage is suppressed. Thus, reduces the risk of damage, which the protection measures can be characterized, by the reduction value of the economic loss to an acceptable level.

Interfacial forces exceed gravitational forces on a scale small relative to the capillary length—two millimeters in the case of an air-water interface—and therefore dominate the physics of sub-millimetric systems. They are of paramount importance for various biological taxa and engineering processes where the motion of a liquid meniscus induces a viscous frictional force that exhibits a sublinear dependence in the meniscus velocity, i.e., a power law with an exponent smaller than one. Interested in the fundamental implications of this dependence, we use a liquid-foam sloshing system as a prototype to exacerbate the effect of sublinear friction on the macroscopic mechanics of multi-phase flows. In contrast to classical theory, we uncover the existence of a finite-time singularity in our system yielding the arrest of the fluid's oscillations. We propose a minimal theoretical framework to capture this effect, thereby amending the paradigmatic damped harmonic oscillator model. Our results suggest that, although often not considered at the macroscale, sublinear capillary forces govern the friction at liquid-solid and liquid-liquid interfaces.

Conclusion: Pulmonary emboli with subsequent right ventricular failure may cause backwards stasis, and parenchymal organ e.g. liver enlargement. The risk for laceration injuries and internal bleed must be acknowledged when applying external forces as in case of cardiac arrest and need for resuscitation. Frequent and vigilant control of positioning of manual as well as mechanical compressions is of importance.

Introduction Mitochondrial injury post-cardiac arrest has been described in pre-clinical settings but the extent to which this injury occurs in humans remains largely unknown. We hypothesized that increased levels of mitochondrial biomarkers would be associated with mortality and neurological morbidity in post-cardiac arrest subjects. Methods We performed a prospective multicenter study of post-cardiac arrest subjects. Inclusion criteria were comatose adults who suffered an out-of-hospital cardiac arrest. Mitochondrial biomarkers were measured at 0, 12, 24, 36 and 48 hours after return of spontaneous circulation as well as in healthy controls. Results Out of 111 subjects enrolled, 102 had evaluable samples at 0 hours. Cardiac arrest subjects had higher baseline cytochrome c levels compared to controls (2.18 ng/mL [0.74, 7.74] vs. 0.16 ng/mL [0.03, 0.91], p<0.001), and subjects who died had higher 0 hours cytochrome c levels compared to survivors (3.66 ng/mL [1.40, 14.9] vs. 1.27 ng/mL [0.16, 2.37], p<0.001). There were significantly higher RNAase P (3.3 [1.2, 5.7] vs. 1.2 [0.8, 1.2], p<0.001) and B2M (12.0 [1.0, 22.9], vs. 0.6 [0.6, 1.3], p<0.001) levels in cardiac arrest subjects at baseline compared to the control subjects. There were no differences between survivors and non-survivors for mitochondrial DNA, nuclear DNA, or cell free DNA. Conclusions Cytochrome C was increased in post-cardiac arrest subjects compared to controls, and in post-cardiac arrest non-survivors compared to survivors. Nuclear DNA and cell free DNA was increased in plasma of post-cardiac arrest subjects. There were no differences in mitochondrial DNA, nuclear DNA, or cell free DNA between survivors and non-survivors. Mitochondrial injury markers showed mixed results in post-arrest period. Future research needs to investigate these differences. PMID:28126408

Eidinemacheilus proudlovei, new species, is described from subterranean waters in the Little Zab River drainage in Iraqi Kurdistan. After the discovery of E. smithi in 1976, E. proudlovei is the second troglomorphic nemacheilid loach found in the Middle East and the second species placed in Eidinemacheilus. Eidinemacheilus proudlovei is distinguished from E. smithi by having 8+8 or 8+7 branched caudal-fin rays, no adipose keel on the caudal peduncle, enlarged jaws and a fully developed head canal system. It furthers differs substantially in its DNA barcode (>8% K2P distance) from all other nemacheilid loaches in the Middle East, Europe and Western India.

Low health literacy is associated with lack of medical information, less use of preventive measures, low medication adherence rates, high health care costs and high risk of hospitalization. The aims were to compare the results of the three health literacy tests, to measure for the first time the health literacy level of Iraqis, to describe the use of standardized health literacy tests, to evaluate reliability and validity of the Arabic versions of these tests, and to investigate whether there is relationship between the participant characteristics and the health literacy level. A convenience sample of 95 subjects was studied in five community pharmacies in Al-Najaf and Babylon governorates, Iraq. Three health literacy tests, the Single Item Literacy Screener (SILS), the New Vital Sign (NVS) and the Short version of the Test of Functional Health Literacy in Adults (S-TOFHLA), were translated in the Arabic language and administered to the pharmacy customers. There were no statistically significant associations between age, gender, education and current education status and NVS score, but there were significant positive associations between the level of education and each one of SILS, New SILS, and S-TOFHLA scores. SILS has one subjective, possibly culturally biased question. Since Iraqis are generally not exposed to reading product labels, the NVS test might be not an accurate measure for them. S-TOFHLA was the most comprehensive test and gave equitable results. The Arabic version of S-TOFHLA can be used to measure health literacy in 22 Arabic speaking countries.

Perioperative cardiac arrests and death on the table represent the most serious complications of surgery and anaesthesia. This paper was designed to study their pattern, causes and outcomes following cardiopulmonary resuscitation (CPR) and intensive care unit (ICU) management in our institution. Three year retrospective review of perioperative cardiac arrests and death on operating table following surgical procedure under anaesthesia. For each cardiac arrest or death on the table the sequence of events leading to the arrest was evaluated using case notes, anaesthetic chart and ICU records. Study variables which include demographic data, ASA score, anaesthetic technique, causes and outcome were analysed and discussed. Fourteen perioperative cardiac arrests were encountered following 4051 anaesthetics administered over the three year study period. Twelve out of the fourteen cardiac arrests occurred following general anaesthesia, while the remaining two occurred following spinal anaesthesia. There was no cardiac arrest following local anaesthesia. Children suffered more cardiac arrest than adults. ASA class III and IV risk status suffered more arrests than ASA I and II. Hypoxia from airway problems was the commonest cause of cardiac arrest followed by septic shock. Monitoring with pulse oximeter was done in only 4 out of the 14 cardiac arrests. Only 2 (14%) out of 14 cardiac arrests recovered to home discharge, one of them with significant neurological deficit. Majority of arrests were due to hypoxia from airway problems that were not detected early There is need to improve on patient monitoring, knowledge of CPR and intensive care so as to improve the outcome of perioperative cardiac arrest.

Typhoid fever imposes a high disease burden worldwide, but resource limitations mean that the burden of typhoid fever in many countries is poorly understood. The authors conducted a prospective surveillance study at the adult and pediatric teaching hospitals in Sulaimania, Iraqi Kurdistan. All patients presenting with an undifferentiated febrile illness consistent with typhoid were eligible for enrollment. Enrolled patients had blood cultures and Brucella serologies performed. Incidence was calculated with reference to census data. Both typhoid fever and brucellosis were common, and the incidence of typhoid fever was 21 cases/100 000 patient-years. Classic disease symptoms were uncommonly observed. Cost-effective surveillance projects to calculate disease burden of typhoid fever are practical and replicable. Typhoid has successfully adapted to the healthcare environment in Sulaimania. Additional work in the region should focus on antibiotic resistance and other enteric pathogens such as Brucella spp. Copyright © 2014 The Authors. Published by Elsevier Ltd.. All rights reserved.

Cell cycle arrest induced by radiation

It is known that various chemical reactions, such as cell cycle arrest, DNA repair and cell killing, can occur within the cells when exposed to ionizing radiation and ultraviolet radiation. Thus protein dynamics involved in such chemical reactions has received considerable attention. In this article, cell cycle regulation is first discussed in terms of the G2/M-phase and the G1/S-phase. Then, radiation-induced cell cycle arrest is reviewed. Cell cycle regulation mechanism involved in the G2 arrest, which is well known to occur when exposed to radiation, has recently been investigated using yeasts. In addition, recent study has yielded a noticeable finding that the G1 arrest can occur with intracellular accumulation of p53 product following ionization radiation. p53 is also shown to play an extremely important role in both DNA repair and cell killing due to DNA damage. Studies on the role of genes in protein groups induced by radiation will hold promise for the elucidation of cell cycle mechanism. (N.K.) 57 refs

Same-Sex and Race-Based Disparities in Statutory Rape Arrests.

Chaffin, Mark; Chenoweth, Stephanie; Letourneau, Elizabeth J

2016-01-01

This study tests a liberation hypothesis for statutory rape incidents, specifically that there may be same-sex and race/ethnicity arrest disparities among statutory rape incidents and that these will be greater among statutory rape than among forcible sex crime incidents. 26,726 reported incidents of statutory rape as defined under state statutes and 96,474 forcible sex crime incidents were extracted from National Incident-Based Reporting System data sets. Arrest outcomes were tested using multilevel modeling. Same-sex statutory rape pairings were rare but had much higher arrest odds. A victim-offender romantic relationship amplified arrest odds for same-sex pairings, but damped arrest odds for male-on-female pairings. Same-sex disparities were larger among statutory than among forcible incidents. Female-on-male incidents had uniformly lower arrest odds. Race/ethnicity effects were smaller than gender effects and more complexly patterned. The findings support the liberation hypothesis for same-sex statutory rape arrest disparities, particularly among same-sex romantic pairings. Support for race/ethnicity-based arrest disparities was limited and mixed. © The Author(s) 2014.

In response to DNA damage, cells arrest at specific stages in the cell cycle. This arrest must fulfill at least 3 requirements: it must be activated promptly; it must be sustained as long as damage is present to prevent loss of genomic information; and after the arrest, cells must re-enter into the appropriate cell cycle phase to ensure proper ploidy. Multiple molecular mechanisms capable of arresting the cell cycle have been identified in mammalian cells; however, it is unknown whether each mechanism meets all 3 requirements or whether they act together to confer specific functions to the arrest. To address this question, we integrated mathematical models describing the cell cycle and the DNA damage signaling networks and tested the contributions of each mechanism to cell cycle arrest and re-entry. Predictions from this model were then tested with quantitative experiments to identify the combined action of arrest mechanisms in irradiated cells. We find that different arrest mechanisms serve indispensable roles in the proper cellular response to DNA damage over time: p53-independent cyclin inactivation confers immediate arrest, whereas p53-dependent cyclin downregulation allows this arrest to be sustained. Additionally, p21-mediated inhibition of cyclin-dependent kinase activity is indispensable for preventing improper cell cycle re-entry and endoreduplication. This work shows that in a complex signaling network, seemingly redundant mechanisms, acting in a concerted fashion, can achieve a specific cellular outcome.

A glimpse at the intricate mosaic of ethnicities from Mesopotamia: Paternal lineages of the Northern Iraqi Arabs, Kurds, Syriacs, Turkmens and Yazidis.

Full Text Available Widely considered as one of the cradles of human civilization, Mesopotamia is largely situated in the Republic of Iraq, which is also the birthplace of the Sumerian, Akkadian, Assyrian and Babylonian civilizations. These lands were subsequently ruled by the Persians, Greeks, Romans, Arabs, Mongolians, Ottomans and finally British prior to the independence. As a direct consequence of this rich history, the contemporary Iraqi population comprises a true mosaic of different ethnicities, which includes Arabs, Kurds, Turkmens, Assyrians, and Yazidis among others. As such, the genetics of the contemporary Iraqi populations are of anthropological and forensic interest. In an effort to contribute to a better understanding of the genetic basis of this ethnic diversity, a total of 500 samples were collected from Northern Iraqi volunteers belonging to five major ethnic groups, namely: Arabs (n = 102, Kurds (n = 104, Turkmens (n = 102, Yazidis (n = 106 and Syriacs (n = 86. 17-loci Y-STR analyses were carried out using the AmpFlSTR Yfiler system, and subsequently in silico haplogroup assignments were made to gain insights from a molecular anthropology perspective. Systematic comparisons of the paternal lineages of these five Northern Iraqi ethnic groups, not only among themselves but also in the context of the larger genetic landscape of the Near East and beyond, were then made through the use of two different genetic distance metric measures and the associated data visualization methods. Taken together, results from the current study suggested the presence of intricate Y-chromosomal lineage patterns among the five ethic groups analyzed, wherein both interconnectivity and independent microvariation were observed in parallel, albeit in a differential manner. Notably, the novel Y-STR data on Turkmens, Syriacs and Yazidis from Northern Iraq constitute the first of its kind in the literature.

OBJECTIVE: To test serum tau as a predictor of neurological outcome after cardiac arrest. METHODS: We measured the neuronal protein tau in serum at 24, 48, and 72 hours after cardiac arrest in 689 patients in the prospective international Target Temperature Management trial. The main outcome...... was poor neurological outcome, defined as Cerebral Performance Categories 3-5 at 6 months. RESULTS: Increased tau was associated with poor outcome at 6 months after cardiac arrest (median = 38.5, interquartile range [IQR] = 5.7-245ng/l in poor vs median = 1.5, IQR = 0.7-2.4ng/l in good outcome, for tau....... The accuracy in predicting outcome by serum tau was equally high for patients randomized to 33 °C and 36 °C targeted temperature after cardiac arrest. INTERPRETATION: Serum tau is a promising novel biomarker for prediction of neurological outcome in patients with cardiac arrest. It may be significantly better...

Background Multicenter data regarding cardiac arrest in children undergoing heart operations are limited. We describe epidemiology and outcomes associated with postoperative cardiac arrest in a large multiinstitutional cohort. Methods Patients younger than 18 years in the Society of Thoracic Surgeons Congenital Heart Surgery Database (2007 through 2012) were included. Patient factors, operative characteristics, and outcomes were described for patients with and without postoperative cardiac arrest. Multivariable models were used to evaluate the association of center volume with cardiac arrest rate and mortality after cardiac arrest, adjusting for patient and procedural factors. Results Of 70,270 patients (97 centers), 1,843 (2.6%) had postoperative cardiac arrest. Younger age, lower weight, and presence of preoperative morbidities (all p < 0.0001) were associated with cardiac arrest. Arrest rate increased with procedural complexity across common benchmark operations, ranging from 0.7% (ventricular septal defect repair) to 12.7% (Norwood operation). Cardiac arrest was associated with significant mortality risk across procedures, ranging from 15.4% to 62.3% (all p < 0.0001). In multivariable analysis, arrest rate was not associated with center volume (odds ratio, 1.06; 95% confidence interval, 0.71 to 1.57 in low- versus high-volume centers). However, mortality after cardiac arrest was higher in low-volume centers (odds ratio, 2.00; 95% confidence interval, 1.52 to 2.63). This association was present for both high- and low-complexity operations. Conclusions Cardiac arrest carries a significant mortality risk across the stratum of procedural complexity. Although arrest rates are not associated with center volume, lower-volume centers have increased mortality after cardiac arrest. Further study of mechanisms to prevent cardiac arrest and to reduce mortality in those with an arrest is warranted. PMID:25443018

Visualizing Vpr-induced G2 arrest and apoptosis.

Directory of Open Access Journals (Sweden)

Tomoyuki Murakami

Full Text Available Vpr is an accessory protein of human immunodeficiency virus type 1 (HIV-1 with multiple functions. The induction of G2 arrest by Vpr plays a particularly important role in efficient viral replication because the transcriptional activity of the HIV-1 long terminal repeat is most active in G2 phase. The regulation of apoptosis by Vpr is also important for immune suppression and pathogenesis during HIV infection. However, it is not known whether Vpr-induced apoptosis depends on the ability of Vpr to induce G2 arrest, and the dynamics of Vpr-induced G2 arrest and apoptosis have not been visualized. We performed time-lapse imaging to examine the temporal relationship between Vpr-induced G2 arrest and apoptosis using HeLa cells containing the fluorescent ubiquitination-based cell cycle indicator2 (Fucci2. The dynamics of G2 arrest and subsequent long-term mitotic cell rounding in cells transfected with the Vpr-expression vector were visualized. These cells underwent nuclear mis-segregation after prolonged mitotic processes and then entered G1 phase. Some cells subsequently displayed evidence of apoptosis after prolonged mitotic processes and nuclear mis-segregation. Interestingly, Vpr-induced apoptosis was seldom observed in S or G2 phase. Likewise, visualization of synchronized HeLa/Fucci2 cells infected with an adenoviral vector expressing Vpr clearly showed that Vpr arrests the cell cycle at G2 phase, but does not induce apoptosis at S or G2 phase. Furthermore, time-lapse imaging of HeLa/Fucci2 cells expressing SCAT3.1, a caspase-3-sensitive fusion protein, clearly demonstrated that Vpr induces caspase-3-dependent apoptosis. Finally, to examine whether the effects of Vpr on G2 arrest and apoptosis were reversible, we performed live-cell imaging of a destabilizing domain fusion Vpr, which enabled rapid stabilization and destabilization by Shield1. The effects of Vpr on G2 arrest and subsequent apoptosis were reversible. This study is the first to

Cardiopulmonary arrest during and proximate to hemodialysis is rare but highly fatal. Studies have examined peridialytic sudden cardiac event risk factors, but no study has considered associates of cardiopulmonary arrests (fatal and nonfatal events including cardiac and respiratory causes). This study was designed to elucidate patient and procedural factors associated with peridialytic cardiopulmonary arrest. Data for this case-control study were taken from the hemodialysis population at Fresenius Medical Care, North America. 924 in-center cardiopulmonary events (cases) and 75,538 controls were identified. Cases and controls were 1 : 5 matched on age, sex, race, and diabetes. Predictors of cardiopulmonary arrest were considered for logistic model inclusion. Missed treatments due to hospitalization, lower body mass, coronary artery disease, heart failure, lower albumin and hemoglobin, lower dialysate potassium, higher serum calcium, greater erythropoietin stimulating agent dose, and normalized protein catabolic rate (J-shaped) were associated with peridialytic cardiopulmonary arrest. Of these, lower albumin, hemoglobin, and body mass index; higher erythropoietin stimulating agent dose; and greater missed sessions had the strongest associations with outcome. Patient health markers and procedural factors are associated with peridialytic cardiopulmonary arrest. In addition to optimizing nutritional status, it may be prudent to limit exposure to low dialysate potassium (<2 K bath) and to use the lowest effective erythropoietin stimulating agent dose.

Dwell-Time Distribution, Long Pausing and Arrest of Single-Ribosome Translation through the mRNA Duplex.

Science.gov (United States)

Xie, Ping

2015-10-09

Proteins in the cell are synthesized by a ribosome translating the genetic information encoded on the single-stranded messenger RNA (mRNA). It has been shown that the ribosome can also translate through the duplex region of the mRNA by unwinding the duplex. Here, based on our proposed model of the ribosome translation through the mRNA duplex we study theoretically the distribution of dwell times of the ribosome translation through the mRNA duplex under the effect of a pulling force externally applied to the ends of the mRNA to unzip the duplex. We provide quantitative explanations of the available single molecule experimental data on the distribution of dwell times with both short and long durations, on rescuing of the long paused ribosomes by raising the pulling force to unzip the duplex, on translational arrests induced by the mRNA duplex and Shine-Dalgarno(SD)-like sequence in the mRNA. The functional consequences of the pauses or arrests caused by the mRNA duplex and the SD sequence are discussed and compared with those obtained from other types of pausing, such as those induced by "hungry" codons or interactions of specific sequences in the nascent chain with the ribosomal exit tunnel.

Two new species of Oxynoemacheilus are described from the Sirvan River drainage in Iraqi Kurdistan. Oxynoemacheilus gyndes, new species, is distinguished by having a very short lateral line, reaching behind the pectoral-fin base, no scales except on the posteriormost part of the caudal peduncle, a slightly emarginate caudal fin and no suborbital groove in males. Oxynoemacheilus hanae, new species, is distinguished by having a midlateral row of elongated blotches, isolated patches of dark-brown spots or blotches on lower flank, a deeply emarginate caudal fin and a suborbital groove in males.

The results of the experiments to determine an effect of UV (254 nm) on human diploid fibroblasts (HDF) arrested with respect to division by using 0.5% fetal calf serum in the culture medium are reported. A fraction of cells from irradiated arrested populations, maintained in the arrested state post-irradiation, was lost from the populations. The extent of cell loss was fluence-dependent and cell strain specific. A Xeroderma pigmentosum cell strain was more sensitive to UV than were normal HDF. No difference in sensitivity were observed when arrested populations established from normal HDF populations of various in vitro ages were used. The length of the pre-irradiation arrested period affected the sensitivity of normal HDF, which appeared more resistant at longer arrested periods, but not the sensitivity of arrested Xeroderma populations. These results suggest that DNA repair processes play a role in maintaining irradiated cells in the arrested state. The suggestion is made that the lethal event caused by UV is an effect on transcription leading to an inhibition of required protein synthesis. (author)

Dole, Mark J; Kissane, Jonathan M

2016-01-01

Medical Logistics (MEDLOG) is a function of the Army's integrated System for Health that provides the medical products and specialized logistics services required to deliver health protection and care under all operational conditions. In unified land operations, MEDLOG is an inherent function of Health Service Support (HSS), which also includes casualty care and medical evacuation. This paper focuses on a few key lessons observed during Operations Enduring Freedom and Iraqi Freedom with direct implications for the support of HSS in future operations as envisioned in the Army Operating Concept and the Joint Concept for Health Services. It also examines a few key enablers that helped mitigate these challenges that are not yet fully acknowledged in Army Medical Department doctrine, policy, and planning.

Dynamic propagation and cleavage crack arrest in bainitic steel

International Nuclear Information System (INIS)

Hajjaj, M.

2006-06-01

In complement of the studies of harmfulness of defects, generally realized in term of initiation, the concept of crack arrest could be used as complementary analyses to the studies of safety. The stop occurs when the stress intensity factor becomes lower than crack arrest toughness (KIa) calculated in elasto-statics (KI ≤ KIa). The aim of this thesis is to understand and predict the stop of a crack propagating at high speed in a 18MND5 steel used in the pressure water reactor (PWR). The test chosen to study crack arrest is the disc thermal shock test. The observations under the scanning electron microscope of the fracture surface showed that the crack arrest always occurs in cleavage mode and that the critical microstructural entity with respect to the propagation and crack arrest corresponds to at least the size of the prior austenitic grain. The numerical analyses in elasto-statics confirm the conservatism of the codified curve of the RCC-M with respect to the values of KIa. The dynamic numerical analyses show that the deceleration of the crack measured at the end of the propagation is related to the global dynamic of the structure (vibrations). The transferability to components of crack arrest toughness obtained from tests analysed in static is thus not assured. The disc thermal shock tests were also modelled by considering a criterion of propagation and arrest of the type 'RKR' characterized by a critical stress sc which depends on the temperature. The results obtained account well for the crack jump measured in experiments as well as the shape of the crack arrest front. (author)

Cardiac arrest due to lymphocytic colitis: a case report

Full Text Available Abstract Introduction We present a case of cardiac arrest due to hypokalemia caused by lymphocytic colitis. Case presentation A 69-year-old Caucasian man presented four months prior to a cardiac arrest with watery diarrhea and was diagnosed with lymphocytic colitis. Our patient experienced a witnessed cardiac arrest at his general practitioner's surgery. Two physicians and the emergency medical services resuscitated our patient for one hour and four minutes before arriving at our university hospital. Our patient was defibrillated 16 times due to the recurrence of ventricular tachyarrhythmias. An arterial blood sample revealed a potassium level of 2.0 mmol/L (reference range: 3.5 to 4.6 mmol/L and pH 6.86 (reference range: pH 7.37 to 7.45. As the potassium level was corrected, the propensity for ventricular tachyarrhythmias ceased. Our patient recovered from his cardiac arrest without any neurological deficit. Further tests and examinations revealed no other reason for the cardiac arrest. Conclusion Diarrhea can cause life-threatening situations due to the excretion of potassium, ultimately causing cardiac arrest due to hypokalemia. Physicians treating patients with severe diarrhea should consider monitoring their electrolyte levels.

Mental health court outcomes: a comparison of re-arrest and re-arrest severity between mental health court and traditional court participants.

Moore, Marlee E; Hiday, Virginia Aldigé

2006-12-01

Mental health courts have been proliferating across the country since their establishment in the late 1990's. Although numerous advocates have proclaimed their merit, only few empirical studies have evaluated their outcomes. This paper evaluates the effect of one mental health court on criminal justice outcomes by examining arrests and offense severity from one year before to one year after entry into the court, and by comparing mental health court participants to comparable traditional criminal court defendants on these measures. Multivariate models support the prediction that mental health courts reduce the number of new arrests and the severity of such re-arrests among mentally ill offenders. Similar analysis of mental health court completers and non-completers supports the prediction that a "full dose" of mental health treatment and court monitoring produce even fewer re-arrests.

ON THE HORNS OF A DILEMMA: INTELLECTUALS BETWEEN THE REGIME AND THE PEOPLE AS REFLECTED IN IRAQI COMMUNIST LITERATURE

Directory of Open Access Journals (Sweden)

Hilla Peled-Shapira

2012-12-01

Full Text Available This paper deals with the way in which Communist writers in mid-twentieth-century Iraq used literature in order to, on the one hand express their tense relationship with the regime during times of severe political repression, and on the other hand sharply criticize the Iraqi people themselves for not taking responsibility for or caring about their fate—or, for that matter, for failing to internalize the social class discourse to which the Communists aspired.  The paper’s objective is to examine the connection between the writers’ ideology and the rhetorical and conceptual elements with which they expressed their dissatisfaction with the regime, the way Iraqi society was run, and the desires of both—intellectuals and society at large—to undergo change. In addition, this study will survey the esthetic and stylistic devices, which the writers under consideration chose, and consider both the meanings and motives behind their choices. These aspects will be examined in the framework of a proposed model of “circles of criticism.”

Senescence of the human diploid fibroblast-like cell line, W138, is characterized by a loss of proliferative activity and an arrest of cells with a 2C DNA content (G1 or G0). To examine the specific region within G1 in which senescent cells arrest, senescent cells were stained with quinacrine dihydrochloride (QDH) and their nuclear fluorescence was compared with that of young cultures arrested in early and late G1 by serum deprivation and hydroxyurea exposure, respectively. Release of these G1-arrested young cultures from their blocking conditions and timing the kinetics of their entry into the S phase by autoradiographic detection of [ 3 H]thymidine incorporation revealed that serum-deprived cells entered the S phase within 15-18h, whereas hydroxyurea-exposed cells entered the S phase within 1.5h, thus confirming their relative G1-arrest positions. QDH-stained, serum-deprived and hydroxyurea-exposed young cells exhibited relative nuclear fluorescence intensities of 51.7 and 23.9, respectively. Senescent cells exhibited a relative nuclear fluorescence intensity of 17.4, closely resembling the fluorescence of young cultures arrested in late G1 by hydroxyurea exposure. These data support the concept that senescent cells are arrested from further progression in the cell cycle in late G1

Although researchers and practitioners have established that men and women use force in their intimate heterosexual relationships for very different reasons, there is a dearth of information regarding the events surrounds women's arrests and subsequent court orders to anti-violence intervention programming. This information is fundamental to improving Criminal Legal System (CLS) and community-partner understanding of and response to intimate partner violence (IPV). The authors meet this need by analyzing 208 women's descriptions of their arrests and subsequent court order to intervention programs for using force. From these, the authors frame nine categorical descriptions of women's actions. The descriptions and categories highlight areas for CLS and community-partners' growing understanding of this complex issue. © The Author(s) 2016.

Maturation arrest of human oocytes at germinal vesicle stage

Directory of Open Access Journals (Sweden)

Zhi Qin Chen

2010-01-01

Full Text Available Maturation arrest of human oocytes may occur at various stages of the cell cycle. A total failure of human oocytes to complete meiosis is rarely observed during assisted conception cycles. We describe here a case of infertile couples for whom all oocytes repeatedly failed to mature at germinal vesicle (GV stage during in vitro fertilization/Intra cytoplasmic sperm injection (IVF/ICSI. The patient underwent controlled ovarian stimulation followed by oocyte retrieval and IVF/ICSI. The oocytes were stripped off cumulus cells prior to the ICSI procedure and their maturity status was defined. The oocyte maturation was repeatedly arrested at the GV. Oocyte maturation arrest may be the cause of infertility in this couple. The recognition of oocyte maturation arrest as a specific medical condition may contribute to the characterization of the currently known as "oocyte factor." The cellular and genetic mechanisms causing oocyte maturation arrest should be the subject for further investigation.

Little is known about the effects of combat exposure on women's health after service in Operation Iraqi Freedom (OIF). Our purpose was to describe the incidence and nature of physical heath symptoms reported by deployed women to identify problematic areas where early intervention or better surveillance might be directed. Using a random, stratified sample (theater vs. non-theater; parent vs. non-parent; and military component including active, guard, and reserve members) of 1,114 Air Force women, we provide descriptive statistics, group comparisons, and multiple regression models to identify health concerns and potential predictors of physical health outcomes. Findings revealed that those in the reserve/guard forces (vs. active duty) and those in the theater of operations (vs. elsewhere during the same time period) reported greater physical health problems (β = -0.07, p social functioning (β = 0.08, p war-related predictors of health among women serving in deployed locations around the world.

Tuberculosis (TB) remains a major public health problem especially in low and middle-income countries. The current study was undertaken to estimate the incidence of the disease and describe its epidemiological characteristics in Iraqi Kurdistan. A retrospective study was carried out on cases registered in the directly observed treatment-short course (DOTS) centers in Sulaimaniyah province. Information was collected from the summary reports of all cases registered in 2010 and detailed information was obtained from 307 cases in the main center. During 2010, a total of 530 new and relapsed cases were registered in the DOTS centers amounting to an annual incidence of 31 per 100,000. Over 73% of cases were pulmonary TB and 45% of all cases had positive smear. Most common symptoms were cough (58%), sweating (49%) and fever (48). Almost 43% of patients were diagnosed by direct swab examination, 30% by biopsy and 23% through clinical and radiologic examination. In relation to outcome, 89% of patients were treated successfully, 7% died and 3% defaulted. Mortality rate was 8% in pulmonary infection and 4% in extrapulmonary infection. Old age (65 years and over) was significantly associated with higher odds of death compared to people aged 34 years and younger (OR 6.7, 95% CI 1.3-36.1, P=0.03). The incidence of TB is still high in the Iraqi Kurdistan. The DOTS has been successful in treating the majority of cases but there are areas needing improvement especially record-keeping and patient follow-up during and after treatment.

Operation Iraqi Freedom/Operation Enduring Freedom: exploring wartime death and bereavement.

Harrington Lamorie, Jill

2011-01-01

Military deaths are often sudden, unanticipated, traumatic, and/or violent in nature and involve the death of a young adult. More than 5,500 service members have died as a result of their service in the wars in Afghanistan (2001) and Iraq (2003) in combat- or non-combat- related incidences. As the death toll continues to rise, service members and their families struggle with the visible and invisible wounds of war. This article explores wartime death, trauma, and bereavement experienced by those survivors affected by service members who have died as a result of their military service in Operation Iraqi Freedom (OIF) and Operation Enduring Freedom (OEF). It recognizes the circumstantial and cultural factors of the death as well as the grief and trauma experiences of survivors. Resources and suggested interventions of support are highlighted.

Iraqi refugees in Lebanon are vulnerable to food insecurity because of their limited rights and fragile livelihoods. The objective of the present study was to assess household food insecurity among Iraqi refugees living in Lebanon, almost 10 years after the invasion of Iraq. A representative survey of 800 UN High Commissioner for Refugees-registered refugee households in Lebanon was conducted using multi-stage cluster random sampling. We measured food insecurity using a modified US Department of Agriculture household food security module. We collected data on household demographic, socio-economic, health, housing and dietary diversity status and analysed these factors by food security status. Hb level was measured in a subset of children below 5 years of age (n 85). Weighted data were used in univariate and multivariate analyses. Among the Iraqi refugee households surveyed (n 630), 20·1% (95% CI 17·3, 23·2) were found to be food secure, 35·5% (95% CI 32·0, 39·2) moderately food insecure and 44·4% (95% CI 40·8, 48·1) severely food insecure. Severe food insecurity was associated with the respondent's good self-reported health (OR 0·3, 95% CI 0·2, 0·5), length of stay as a refugee (OR 1·1, 95% CI 1·0, 1·2), very poor housing quality (OR 3·3, 95% CI 1·6, 6·5) and the number of children in the household (OR 1·2, 95% CI 1·0, 1·4), and resulted in poor dietary diversity (PLebanon call for urgent programmes to address the food and health situation of this population with restricted rights.

Protective force legal issues: the security perspective

There has been much discussion and some controversy on the legal issues faced by the Department of Energy's (DOE) protective forces in the performance of their security duties. These include the observance of legal proprieties in the arrest of non-violent demonstrators, the use of lethal weapons, and the extent of protective forces' authority to carry weapons and protect DOE's security interests offsite. In brief, the need to protect DOE's security interests may be in nominal conflict with other requirements. When faced with a potential conflict in requirements, we in the DOE security community must place first attention to the security mission -- to deter and prevent hostile acts

2017-10-01

The purpose of this study was to examine coping strategies used by Iraqi refugees in Jordan based on their demographic details. A cross-sectional design was used. A representative sample of 333 refugees living in Jordan participated in the study. The Cope inventory and the demographic details were compiled to produce and collate the relevant data. Being older, female, educated, single, and living with more than three family members was associated with greater use of the problem solving coping strategy. Being female, educated, and unemployed was associated with greater use of the active emotional coping strategy. In addition, being older, male, illiterate, unemployed, and living with less than three family members was associated with greater use of the avoidant emotional coping strategy. This study recommends a multidisciplinary approach intervention as being the best method of addressing and fulfilling the health and socioeconomic needs of older, male, illiterate, unemployed people.

A new fracture test specimen has been developed to study crack extension and arrest in nuclear reactor vessel steels subject to stress-intensity factor and toughness gradients similar to those in postulated pressurized thermal shock situations. A summary of the results of all the tests performed is presented to illustrate the range of crack arrest and crack reinitiation conditions observed. One test of this specimen with the corresponding stress analysis is described in detail. During this test the crack initiated, extended, arrested, reinitiated, extended again, and reached a final arrest. Comparison of detailed dynamic elastic-plastic finite-element analyses and dynamic strain and displacement measurements of the crack extension, arrest, and reinitiation events, combined with topographic analysis of the future surfaces, has led to a new understanding of the crack extension and arrest process. The results of the tests demonstrate crack arrest in rising stress-intensity field at near-upper-shelf temperature conditions and show that the toughness required for arrest is lower than would be predicted by the analysis procedures usually employed for pressurized thermal shock evaluations

The geometry of empty space is the key to arresting dynamics

We present the concept of dynamically available volume as a suitable order parameter for dynamical arrest. We show that dynamical arrest can be understood as a de-percolation transition of a vacancy network or available space. Beyond the arrest transition we find that droplets of available space are disconnected and the dynamics is frozen. This connection of the dynamics to the underlying geometrical structure of empty space provides us with a rich framework for studying the arrest transition.

Full Text Available Cardiac arrest can occur following a myriad of clinical conditions. With advancement of medical science and improvements in Emergency Medical Services systems, the rate of return of spontaneous circulation for patients who suffer an out-of-hospital cardiac arrest (OHCA continues to increase. Managing these patients is challenging and requires a structured approach including stabilization of cardiopulmonary status, early consideration of neuroprotective strategies, identifying and managing the etiology of arrest and initiating treatment to prevent recurrence. This requires a closely coordinated multidisciplinary team effort. In this article, we will review the initial management of survivors of OHCA, highlighting advances and ongoing controversies.

Communication between members of the cardiac arrest team--a postal survey.

Effective communication enhances team building and is perceived to improve the quality of team performance. A recent publication from the Resuscitation Council (UK) has highlighted this fact and recommended that cardiac arrest team members make contact daily. We wished to identify how often members of this team communicate prior to a cardiopulmonary arrest. A questionnaire on cardiac arrest team composition, leadership, communication and debriefing was distributed nationally to Resuscitation Training Officers (RTOs) and their responses analysed. One hundred and thirty (55%) RTOs replied. Physicians and anaesthetists were the most prominent members of the team. The Medical Senior House Officer is usually nominated as the team leader. Eighty-seven centres (67%) have no communication between team members prior to attending a cardiopulmonary arrest. In 33%, communication occurs but is either informal or fortuitous. The RTOs felt that communication is important to enhance team dynamics and optimise task allocation. Only 7% achieve a formal debrief following a cardiac arrest. Communication between members of the cardiac arrest team before and after a cardiac arrest is poor. Training and development of these skills may improve performance and should be prioritised. Team leadership does not necessarily reflect experience or training.

Full Text Available The 4-H volunteer program is a new concept to the people of Iraq, for decades the country has been closed to western ideas. Iraqi culture and the Arabic customs have not embraced the volunteer concept and even more the concept of scientific animal production technologies designed to increase profitability for producers. In 2011 the USAID-Inma Agribusiness program teamed with the Iraq 4-H program to create youth and community entrepreneurship opportunities for widowed families. Iraq 4-H provided the youth members and adult volunteers and Inma provided the financial capital (livestock and the animal science training program for the volunteers. The purpose of this study was to measure the knowledge level gained through intensive animal science training for Iraqi 4-H volunteers. Researchers designed and implemented a pre and post test to measure the knowledge of fifteen volunteers who participated in the three day course. The pretest exposed a general lack of animal science knowledge of all volunteers; over 80% of the participants incorrectly answered the questions. However, the post-test indicated positive change in the participants understanding of animal science production principles.

Current Pharmacological Advances in the Treatment of Cardiac Arrest

Directory of Open Access Journals (Sweden)

Andry Papastylianou

2012-01-01

Full Text Available Cardiac arrest is defined as the sudden cessation of spontaneous ventilation and circulation. Within 15 seconds of cardiac arrest, the patient loses consciousness, electroencephalogram becomes flat after 30 seconds, pupils dilate fully after 60 seconds, and cerebral damage takes place within 90–300 seconds. It is essential to act immediately as irreversible damage can occur in a short time. Cardiopulmonary resuscitation (CPR is an attempt to restore spontaneous circulation through a broad range of interventions which are early defibrillation, high-quality and uninterrupted chest compressions, advanced airway interventions, and pharmacological interventions. Drugs should be considered only after initial shocks have been delivered (when indicated and chest compressions and ventilation have been started. During cardiopulmonary resuscitation, no specific drug therapy has been shown to improve survival to hospital discharge after cardiac arrest, and only few drugs have a proven benefit for short-term survival. This paper reviews current pharmacological treatment of cardiac arrest. There are three groups of drugs relevant to the management of cardiac arrest: vasopressors, antiarrhythmics, and other drugs such as sodium bicarbonate, calcium, magnesium, atropine, fibrinolytic drugs, and corticosteroids.

We investigated the risk of sudden cardiac arrest in association with the recent loss of, or separation from, a family member or friend. Our case-crossover study included 490 apparently healthy married residents of King County, Washington, who suffered sudden cardiac arrest between 1988 and 2005. We compared exposure to spouse-reported family/friend events occurring ≤ 1 month before sudden cardiac arrest with events occurring in the previous 5 months. We evaluated potential effect modification by habitual vigorous physical activity. Recent family/friend events were associated with a higher risk of sudden cardiac arrest (odds ratio [OR] = 1.6; 95% confidence interval [CI] = 1.1-2.4). ORs for cases with and without habitual vigorous physical activity were 1.1 (0.6-2.2) and 2.0 (1.2-3.1), respectively (interaction P = 0.02). These results suggest family/friend events may trigger sudden cardiac arrest and raise the hypothesis that habitual vigorous physical activity may lower susceptibility to these potential triggers.

Full Text Available Background. The polymorphism R229Q is one of the most commonly reported podocin sequence variations among steroid-resistant nephrotic syndromes (SRNS. Aim of the Study. We investigated the frequency and risk of this polymorphism among a group of Iraqi children with SRNS and steroid-sensitive nephrotic syndrome (SSNS. Patients and Methods. A prospective case control study which was conducted in Al-Imamein Al-Kadhimein Medical City, spanning the period from the 1st of April 2015 to 30th of November 2015. Study sample consisted of 54 children having NS, divided into 2 groups: patients group consisted of 27 children with SRNS, and control group involved 27 children with SSNS. Both were screened by real time polymerase chain reaction for R229Q in exon 5 of NPHS2 gene. Results. Molecular study showed R229Q polymorphism in 96.3% of SRNS and 100% of SSNS. There were no phenotypic or histologic characteristics of patients bearing homozygous R229Q polymorphism and the patients with heterozygous R229Q polymorphism. Conclusion. Polymorphism R229Q of NPHS2 gene is prevalent in Iraqi children with SRNS and SSNS. Further study needs to be done, for other exons and polymorphism of NPHS2 gene in those patients.

Ventilation and gas exchange management after cardiac arrest.

Sutherasan, Yuda; Raimondo, Pasquale; Pelosi, Paolo

2015-12-01

For several decades, physicians had integrated several interventions aiming to improve the outcomes in post-cardiac arrest patients. However, the mortality rate after cardiac arrest is still as high as 50%. Post-cardiac arrest syndrome is associated with high morbidity and mortality due to not only poor neurological outcome and cardiovascular failure but also respiratory dysfunction. To minimize ventilator-associated lung injury, protective mechanical ventilation by using low tidal volume ventilation and driving pressure may decrease pulmonary complications and improve survival. Low level of positive end-expiratory pressure (PEEP) can be initiated and titrated with careful cardiac output and respiratory mechanics monitoring. Furthermore, optimizing gas exchange by avoiding hypoxia and hyperoxia as well as maintaining normocarbia may improve neurological and survival outcome. Early multidisciplinary cardiac rehabilitation intervention is recommended. Minimally invasive monitoring techniques, that is, echocardiography, transpulmonary thermodilution method measuring extravascular lung water, as well as transcranial Doppler ultrasound, might be useful to improve appropriate management of post-cardiac arrest patients.

Sabri, Manhal Isam; Hussain, Azham

2017-10-01

Mobile utilization has rapidly expanded due to its feasibility in executing different applications that can be used in solving everyday problems. Common issues in daily life include electricity saving. In Iraq, the Ministry of Power seriously faces such issue. This is because most households have lack access to information regarding to sufficient power consumption, as well as applications that educate about such saving. Therefore, this study aims at developing a mobile application for Iraqi to help them understand the basis for reducing electricity consumption based on the meter data supplied by the users for square meter along with the active devices and period of usage. The proposed mobile application was evaluated by 50 households from the perspective of ease of use, usefulness, ease of learning, and satisfaction. The obtained result showed that majority of the participants found the application to be ease to use, useful, easy to learn, and were satisfied with its functionalities. The study findings provide some insights about the importance of using mobile application for promoting households in Iraq to manage their power consumption behavior.

The neighborhood context of racial and ethnic disparities in arrest.

Science.gov (United States)

Kirk, David S

2008-02-01

This study assesses the role of social context in explaining racial and ethnic disparities in arrest, with afocus on how distinct neighborhood contexts in which different racial and ethnic groups reside explain variations in criminal outcomes. To do so, I utilize a multilevel, longitudinal research design, combining individual-level data with contextual data from the Project on Human Development in Chicago Neighborhoods (PHDCN). Findings reveal that black youths face multiple layers of disadvantage relative to other racial and ethnic groups, and these layers work to create differences in arrest. At the family level, results show that disadvantages in the form of unstable family structures explain much of the disparities in arrest across race and ethnicity. At the neighborhood level, black youths tend to reside in areas with both significantly higher levels of concentrated poverty than other youths as well as lower levels of collective efficacy than white youths. Variations in neighborhood tolerance of deviance across groups explain little of the arrest disparities, yet tolerance of deviance does influence the frequency with which a crime ultimately ends in an arrest. Even after accounting for relevant demographic, family, and neighborhood-level predictors, substantial residual arrest differences remain between black youths and youths of other racial and ethnic groups.

2012-01-01

The present work aimed at investigating the compositions and microstructures of some archaeological samples which dated back to various periods of the ancient Iraqi civilizations using PIXE, XRF, XRD, and SEM techniques. The models selected for the study (ceramics, glaze, etc.) were diverse in size and nature, therefore a limited number of samples were then butted from them by a small diamond wheel. Conventional powder metallurgy method was then used to prepare the samples. Dried samples were then coated with a thin layer of carbon, and analyzed using the ion beam accelerator of the LAEC. Three other groups of samples were also prepared for the purpose of analysis by X-ray fluorescence (XRF), X-ray diffraction (XRD), and scanning electron microscope (SEM). Analysis results of the chemical composition showed good agreement between the various techniques as well as for phases, while the fine structure analysis obtained by optical and scanning microscopy exhibited features of a structure where it got an intensified densification in the final stage of sintering and accompanied by quasi-homogeneous distribution of the closed pores. This will lead to the conclusion that the temperature used for sintering by ancient Iraqi was sufficient and it may fall in the range between 950-1200°C, also the mixes and the forming methods used by them, were both suitable to obtain good sintered bodies with even distribution of pores. A ring-shaped trace noticed in SEM micrographs need more work and study to explain what it is?

Arrest in flagrante delicto as a measure restricting the Right to Freedom

Directory of Open Access Journals (Sweden)

Majlinda Andrea

2015-11-01

Full Text Available Arrest in flagrante delicto is one of the cases in which the international and national legal framework allows the restriction of the right to freedom. Currently, the individual and his fundamental rights are in the focus of human society. Some of them are absolute and some others have a relative character. The right to freedom, notwithstanding its importance, is a right of relative character but with cases of its restriction exhaustively defined. The protection of this right is extended both in horizontal perspective versus the actions of other persons, providing a legal-criminal defense and in vertical context, in the face of repressive power of the state, which adopted the most significant position in the case of someone’s arrest or detention. The latter constitute an indicator of an incomparable relation between the force of state power and a person’s vulnerability. The exact meaning of arrest in flagrante delicto and its application only in the conditions and criteria set out by the criminal procedural legislation prevents arbitrary restriction of the right to freedom. A key importance in the analysis of this institute is attached to ECtHR jurisprudence that is consolidated and detailed in addressing the right to freedom. The respect and application of standards affirmed by this court on part of the state institutions directly affects the consolidation of rule of law. The criminal procedural legislation has consented to the general principle according to which “only the judge has the power to apply a security measure restricting personal liberty, a measure that has continuous effects over time, although such measures have a specific maximum duration”. According to this approach, the arrest in flagrante delicto is qualified due to its character, as a temporary measure applied in situations of emergency when the procedure for security measure cannot be effectively applied. As already known, it is linked with the power of judicial

An overview is given of the efforts underway in the Heavy-Section Steel Technology (HSST) Program to better understand and model crack-arrest behavior in reactor pressure vessel steels. The efforts are both experimental and analytical. The experimental work provides K/sub Ia/ data from laboratory-sized specimens, from thick-wall cylinders which exhibit essentially-full restraint and from nonisothermal wide-plate specimens. These data serve to define toughness-temperature trends and to provide validation data under prototypical reactor conditions. The analytical efforts interpret and correlate the data, plus provide LEFM, elastodynamic and viscoplastic methods for analyzing crack run-arrest behavior in reactor vessels. The analysis methods are incorporated into finite element computer programs which are under development at three separate laboratories. 22 refs., 10 figs

Cardiac arrest following ventilator fire: A rare cause

K Nazeer Ahmed

2012-01-01

Full Text Available Operating room fires are rare events, but when occur they result in serious and sometimes fatal consequences. Anaesthesia ventilator fire leading to cardiac arrest is a rare incident and has not been reported. We report a near catastrophic ventilator fire leading to cardiac arrest in a patient undergoing subtotal thyroidectomy. In the present case sparks due to friction or electrical short circuit within the ventilator might have acted as source of ignition leading to fire and explosion in the oxygen rich environment. The patient was successfully resuscitated and revived with uneventful recovery and no adverse sequelae. The cardiac arrest was possibly due to severe hypoxia resulting from inhalation of smoke containing high concentrations of carbon monoxide and other noxious gases.

Perioperative cardiac arrest: an evolutionary analysis of the intra-operative cardiac arrest incidence in tertiary centers in Brazil

Directory of Open Access Journals (Sweden)

Matheus Fachini Vane

2016-03-01

Full Text Available Background: Great changes in medicine have taken place over the last 25 years worldwide. These changes in technologies, patient risks, patient profile, and laws regulating the medicine have impacted the incidence of cardiac arrest. It has been postulated that the incidence of intraoperative cardiac arrest has decreased over the years, especially in developed countries. The authors hypothesized that, as in the rest of the world, the incidence of intraoperative cardiac arrest is decreasing in Brazil, a developing country. Objectives: The aim of this study was to search the literature to evaluate the publications that relate the incidence of intraoperative cardiac arrest in Brazil and analyze the trend in the incidence of intraoperative cardiac arrest. Contents: There were 4 articles that met our inclusion criteria, resulting in 204,072 patients undergoing regional or general anesthesia in two tertiary and academic hospitals, totalizing 627 cases of intraoperative cardiac arrest. The mean intraoperative cardiac arrest incidence for the 25 years period was 30.72:10,000 anesthesias. There was a decrease from 39:10,000 anesthesias to 13:10,000 anesthesias in the analyzed period, with the related lethality from 48.3% to 30.8%. Also, the main causes of anesthesia-related cause of mortality changed from machine malfunction and drug overdose to hypovolemia and respiratory causes. Conclusions: There was a clear reduction in the incidence of intraoperative cardiac arrest in the last 25 years in Brazil. This reduction is seen worldwide and might be a result of multiple factors, including new laws regulating the medicine in Brazil, incorporation of technologies, better human development level of the country, and better patient care.

Abstract Out of hospital cardiac arrest (OHCA) is a leading cause of death worldwide. Developing countries including Lebanon report low survival rates and poor neurologic outcomes in affected victims. Community involvement through early recognition and bystander cardiopulmonary resuscitation (CPR) can improve OHCA survival. This study assesses knowledge and attitude of university students in Lebanon and identifies potential barriers and facilitators to learning and performing CPR. A cross-sectional survey was administered to university students. The questionnaire included questions regarding the following data elements: demographics, knowledge, and awareness about sudden cardiac arrest, CPR, automated external defibrillator (AED) use, prior CPR and AED training, ability to perform CPR or use AED, barriers to performing/learning CPR/AED, and preferred location for attending CPR/AED courses. Descriptive analysis followed by multivariate analysis was carried out to identify predictors and barriers to learning and performing CPR. A total of 948 students completed the survey. Participants’ mean age was 20.1 (±2.1) years with 53.1% women. Less than half of participants (42.9%) were able to identify all the presenting signs of cardiac arrest. Only 33.7% of participants felt able to perform CPR when witnessing a cardiac arrest. Fewer participants (20.3%) reported receiving previous CPR training. Several perceived barriers to learning and performing CPR were also reported. Significant predictors of willingness to perform CPR when faced with a cardiac arrest were: earning higher income, previous CPR training and feeling confident in one's ability to apply an AED, or perform CPR. Lacking enough expertise in performing CPR was a significant barrier to willingness to perform CPR. University students in Lebanon are familiar with the symptoms of cardiac arrest, however, they are not well trained in CPR and lack confidence to perform it. The attitude towards the importance of

The exposure of mammalian cells to X rays results in the prolongation of the cell cycle, including the delay or the arrest in G 1 , S and G 2 phase. The major function of G 1 arrest may be to eliminate the cells containing DNA damage and only occurs in the cells with wild type p53 function whereas G 2 arrest following ionizing radiation has been shown to be important in protecting the cells from death and occurs in all cells regardless of p53 status. So the study on G 2 phase arrest of the cell cycle induced by ionizing radiation has currently become a focus at radiobiological fields

Cell cycle age dependence for radiation-induced G2 arrest: evidence for time-dependent repair

International Nuclear Information System (INIS)

Rowley, R.

1985-01-01

Exponentially growing eucaryotic cells, irradiated in interphase, are delayed in progression to mitosis chiefly by arrest in G 2 . The sensitivity of Chinese hamster ovary cells to G 2 arrest induction by X rays increases through the cell cycle, up to the X-ray transition point (TP) in G 2 . This age response can be explained by cell cycle age-dependent changes in susceptibility of the target(s) for G 2 arrest and/or by changes in capability for postirradiation recovery from G 2 arrest damage. Discrimination between sensitivity changes and repair phenomena is possible only if the level of G 2 arrest-causing damage sustained by a cell at the time of irradiation and the level ultimately expressed as arrest can be determined. The ability of caffeine to ameliorate radiation-induced G 2 arrest, while inhibiting repair of G 2 arrest-causing damage makes such an analysis possible. In the presence of caffeine, progression of irradiated cells was relatively unperturbed, but on caffeine removal, G 2 arrest was expressed. The duration of G 2 arrest was independent of the length of the prior caffeine exposure. This finding indicates that the target for G 2 arrest induction is present throughout the cell cycle and that the level of G 2 arrest damage incurred is initially constant for all cell cycle phases. The data are consistent with the existence of a time-dependent recovery mechanism to explain the age dependence for radiation induction of G 2 arrest

There were no limits on language or publication dates.Study selectionTwo reviewers selected prospective clinical studies investigating SDF treatment for caries prevention in children.Data extraction and synthesisData was abstracted independently by two reviewers and risk of bias assessed. Meta-analysis was performed on studies in which the caries-arresting rate using 38% SDF solution on primary teeth could be obtained or calculated.ResultsNineteen studies were included; 16 were conducted in the primary dentition and three in permanent dentition. Fourteen studies used 38% SDF, three 30% SDF, and two 10% SDF. Eight studies using 38% SDF contributed to a meta-analysis and the overall proportion of arrested caries was 81% (95% CI; 68-89%). Percentage reductions were also calculated for 6,12,18,24 and >30 months. Arrested carious lesions stained black but no other adverse effects were reported.ConclusionsSDF commonly used at a high concentration (38%, 44,800ppm fluoride) is effective in arresting caries among children. There is no consensus on its number and frequency of application to arrest caries. Further studies are necessary to develop evidence-based guidelines on its use in children.

Early Recognition of Foreign Body Aspiration as the Cause of Cardiac Arrest

Directory of Open Access Journals (Sweden)

Muhammad Kashif

2016-01-01

Full Text Available Foreign body aspiration (FBA is uncommon in the adult population but can be a life-threatening condition. Clinical manifestations vary according to the degree of airway obstruction, and, in some cases, making the correct diagnosis requires a high level of clinical suspicion combined with a detailed history and exam. Sudden cardiac arrest after FBA may occur secondary to asphyxiation. We present a 48-year-old male with no history of cardiac disease brought to the emergency department after an out-of-hospital cardiac arrest (OHCA. The patient was resuscitated after 15 minutes of cardiac arrest. He was initially managed with therapeutic hypothermia (TH. Subsequent history suggested FBA as a possible etiology of the cardiac arrest, and fiberoptic bronchoscopy demonstrated a piece of meat and bone lodged in the left main stem bronchus. The foreign body was removed with the bronchoscope and the patient clinically improved with full neurological recovery. Therapeutic hypothermia following cardiac arrest due to asphyxia has been reported to have high mortality and poor neurological outcomes. This case highlights the importance of early identification of FBA causing cardiac arrest, and we report a positive neurological outcome for postresuscitation therapeutic hypothermia following cardiac arrest due to asphyxia.

Twenty Reserve component (Army and Marines) and Army National Guard male veterans of Operational Enduring Freedom/Operation Iraqi Freedom discuss their deployment and postdeployment family reintegration experiences. A Grounded Theory approach is used to highlight some of the ways in which family miscommunication during deployment can occur. Communication with civilian family members is affected by the needs of operational security, technical problems with communication tools, miscommunication between family members, or because veterans have "nothing new to say" to family back home. These communication difficulties may lead to an initial gulf of understanding between veterans and family members that can cause family strain during postdeployment family reintegration. We end with a discussion of veteran family reintegration difficulties.

Keyes, Paul H; Rams, Thomas E

An inverse relationship between dental calculus mineralization and dental caries demineralization on teeth has been noted in some studies. Dental calculus may even form superficial layers over existing dental caries and arrest their progression, but this phenomenon has been only rarely documented and infrequently considered in the field of Cariology. To further assess the occurrence of dental calculus arrest of dental caries, this study evaluated a large number of extracted human teeth for the presence and location of dental caries, dental calculus, and dental plaque biofilms. A total of 1,200 teeth were preserved in 10% buffered formal saline, and viewed while moist by a single experienced examiner using a research stereomicroscope at 15-25× magnification. Representative teeth were sectioned and photographed, and their dental plaque biofilms subjected to gram-stain examination with light microscopy at 100× magnification. Dental calculus was observed on 1,140 (95%) of the extracted human teeth, and no dental carious lesions were found underlying dental calculus-covered surfaces on 1,139 of these teeth. However, dental calculus arrest of dental caries was found on one (0.54%) of 187 evaluated teeth that presented with unrestored proximal enamel caries. On the distal surface of a maxillary premolar tooth, dental calculus mineralization filled the outer surface cavitation of an incipient dental caries lesion. The dental calculus-covered carious lesion extended only slightly into enamel, and exhibited a brown pigmentation characteristic of inactive or arrested dental caries. In contrast, the tooth's mesial surface, without a superficial layer of dental calculus, had a large carious lesion going through enamel and deep into dentin. These observations further document the potential protective effects of dental calculus mineralization against dental caries.

2018-04-01

Insects enter diapause to synchronise their life cycle with biotic and abiotic environmental conditions favourable for their development, reproduction, and survival. One of the most noticeable characteristics of diapause is the blockage of ontogeny. Although this blockage should occur with the cessation of cellular proliferation, i.e. cell cycle arrest, it was confirmed only in a few insect species and information on the molecular pathways involved in cell cycle arrest is limited. In the present study, we investigated developmental and cell cycle arrest in diapause larvae of the jewel wasp Nasonia vitripennis. Developmental and cell cycle arrest occur in the early fourth instar larval stage of N. vitripennis under short days. By entering diapause, the S fraction of the cell cycle disappears and approximately 80% and 20% of cells arrest their cell cycle in the G0/G1 and G2 phases, respectively. We further investigated expression of cell cycle regulatory genes and some housekeeping genes to dissect molecular mechanisms underlying the cell cycle arrest. Copyright © 2016 Elsevier Ltd.

2018-05-05

By the end of the year 2016, approximately 3 billion people worldwide travelled by commercial air transport. Between 1 out of 14,000 and 1 out of 50,000 passengers will experience acute medical problems/emergencies during a flight (i.e., in-flight medical emergency). Cardiac arrest accounts for 0.3% of all in-flight medical emergencies. So far, no specific guideline exists for the management and treatment of in-flight cardiac arrest (IFCA). A task force with clinical and investigational expertise in aviation, aviation medicine, and emergency medicine was created to develop a consensus based on scientific evidence and compiled a guideline for the management and treatment of in-flight cardiac arrests. Using the GRADE, RAND, and DELPHI methods, a systematic literature search was performed in PubMed. Specific recommendations have been developed for the treatment of IFCA. A total of 29 specific recommendations for the treatment and management of in-flight cardiac arrests were generated. The main recommendations included emergency equipments as well as communication of the emergency. Training of the crew is of utmost importance, and should ideally have a focus on CPR in aircraft. The decision for a diversion should be considered very carefully.

Despite plans of calling back the skilled health workforce, they are still worried by the disadvantages of their return. Hence, technology plays a central role in taking advantage of their profession through the use of telemedicine. Studying the factors that affect the implementation of telemedicine is necessary. Telemedicine covers network services, policy makers, and patient understanding. A framework that includes the influencing factors in adopting telemedicine in Iraq was developed in this study. A questionnaire was distributed among physicians in Baghdad Medical City to examine the hypothesis on each factor. The Statistical Package for the Social Sciences was utilized to verify the reliability of the questionnaire and Cronbach’s alpha test shows that the factors have values more than 0.7, which are standard.

Although kidnapping is common in war-torn countries, there is little research examining its psychological effects. Iraqi refugees (N = 298) were assessed upon arrival to the U.S. and 1 year later. At arrival, refugees were asked about prior trauma exposure, including kidnapping. One year later refugees were assessed for posttraumatic stress disorder (PTSD) and major depression disorder (MDD) using the SCID-I. Individual resilience and narratives of the kidnapping were also assessed. Twenty-six refugees (9 %) reported being kidnapped. Compared to those not kidnapped, those who were had a higher prevalence of PTSD, but not MDD, diagnoses. Analyses examining kidnapping victims revealed that higher resilience was associated with lower rates of PTSD. Narratives of the kidnapping were also discussed. This study suggests kidnapping is associated with PTSD, but not MDD. Additionally, kidnapping victims without PTSD reported higher individual resilience. Future studies should further elucidate risk and resilience mechanisms.

Full Text Available It is vital in any industry to regain the spent capitals plus running costs and a margin of profits for the industry to flourish. The electricity industry is an everyday life touching industry which follows the same finance-economic strategy. Cost allocation is a major issue in all sectors of the electric industry, viz, generation, transmission and distribution. Generation and distribution service costing’s well documented in the literature, while the transmission share is still of need for research. In this work, the cost of supplying a bulk electric load connected to the EHV system is calculated. A sample basic lump-average method is used to provide a rough costing guide. Also, two transmission pricing methods are employed, namely, the postage-stamp and the load-flow based MW-distance methods to calculate transmission share in the total cost of each individual bulk load. The three costing methods results are then analyzed and compared for the 400kV Iraqi power grid considered for a case study.

2015-12-01

Full Text Available This paper introduces the indicators for surge arrester condition assessment based on the leakage current analysis. Maximum amplitude of fundamental harmonic of the resistive leakage current, maximum amplitude of third harmonic of the resistive leakage current and maximum amplitude of fundamental harmonic of the capacitive leakage current were used as indicators for surge arrester condition monitoring. Also, the effects of operating voltage fluctuation, third harmonic of voltage, overvoltage and surge arrester aging on these indicators were studied. Then, obtained data are applied to the multi-layer support vector machine for recognizing of surge arrester conditions. Obtained results show that introduced indicators have the high ability for evaluation of surge arrester conditions.

Dynamical principles of cell-cycle arrest: Reversible, irreversible, and mixed strategies

Science.gov (United States)

Pfeuty, Benjamin

Living cells often alternate between proliferating and nonproliferating states as part of individual or collective strategies to adapt to complex and changing environments. To this aim, they have evolved a biochemical regulatory network enabling them to switch between cell-division cycles (i.e., oscillatory state) and cell-cycle arrests (i.e., steady state) in response to extracellular cues. This can be achieved by means of a variety of bifurcation mechanisms that potentially give rise to qualitatively distinct cell-cycle arrest properties. In this paper, we study the dynamics of a minimal biochemical network model in which a cell-division oscillator and a differentiation switch mutually antagonize. We identify the existence of three biologically plausible bifurcation scenarios organized around a codimension-four swallowtail-homoclinic singularity. As a result, the model exhibits a broad repertoire of cell-cycle arrest properties in terms of reversibility of these arrests, tunability of interdivision time, and ability to track time-varying signals. This dynamic versatility would explain the diversity of cell-cycle arrest strategies developed in different living species and functional contexts.

Juvenile Arrest and Collateral Educational Damage in the Transition to Adulthood

Official sanctioning of students by the criminal justice system is a long-hypothesized source of educational disadvantage, but its explanatory status remains unresolved. Few studies of the educational consequences of a criminal record account for alternative explanations such as low self-control, lack of parental supervision, deviant peers, and neighborhood disadvantage. Moreover, virtually no research on the effect of a criminal record has examined the “black box” of mediating mechanisms or the consequence of arrest for postsecondary educational attainment. Analyzing longitudinal data with multiple and independent assessments of theoretically relevant domains, this paper estimates the direct effect of arrest on later high school dropout and college enrollment for adolescents with otherwise equivalent neighborhood, school, family, peer, and individual characteristics as well as similar frequency of criminal offending. We present evidence that arrest has a substantively large and robust impact on dropping out of high school among Chicago public school students. We also find a significant gap in four-year college enrollment between arrested and otherwise similar youth without a criminal record. We assess intervening mechanisms hypothesized to explain the process by which arrest disrupts the schooling process, and, in turn, produces collateral educational damage. The results imply that institutional responses and disruptions in students’ educational trajectories, rather than social psychological factors, are responsible for the arrest-education link.

Developments of the theory, the analyses and the materials characterization for assessments of crack arrest in heavy walled nuclear pressure vessels are described. A two-dimensional, dynamic, finite difference analysis of crack propagation and arrest, including inertia forces and thermal stresses is derived. The analysis is used to treat run-arrest events in DCB- and SEN-specimens. Calculations based on the one-dimensional analysis are compared with detailed measurements of run-arrest in two polymeric materials. The agreements between calculations and experiments support the dynamic, energy conservation theory of crack arrest. Implications of a K/sub ID/-crack velocity curve with a negative slope are examined. The quantity K/sub Im/, the minimum propagating crack toughness, is identified as the crack arrest material property for engineering applications. Considerations entering the design of a crack arrest property measuring procedure, including specimen shape, size, thickness and the crack jump are discussed. The influence of side grooves on the propensity for crack branching is examined. Compliance measurements for rectangular DCB-specimens are presented and analyzed. Energy losses arising from damping remote from the crack tip in an A533B steel DCB specimen are described, and classed as negligible. Interactions between test pieces and the loading system are examined. A simplified procedure for measuring K/sub D/-, K/sub m/-, and K/sub a/-values, based on the dynamic analysis of the crack length at arrest is demonstrated. Measurements of K/sub D/ at temperatures in the range (NDT-66)C to (NDT +34)C and for crack velocities in the range 200 ms -1 to 1000 ms -1 are presented. The connection between propagating crack toughness values and the rapidly loaded stationary crack toughness K/sub Id/ is examined

A new on-line leakage current monitoring system of ZnO surge arresters

International Nuclear Information System (INIS)

Lee, Bok-Hee; Kang, Sung-Man

2005-01-01

This paper presents a new on-line leakage current monitoring system of zinc oxide (ZnO) surge arresters. To effectively diagnose the deterioration of ZnO surge arresters, a new algorithm and on-line leakage current detection device, which uses the time-delay addition method, for discriminating the resistive and capacitive currents was developed to use in the aging test and durability evaluation for ZnO arrester blocks. A computer-based measurement system of the resistive leakage current, the on-line monitoring device can detect accurately the leakage currents flowing through ZnO surge arresters for power frequency ac applied voltages. The proposed on-line leakage current monitoring device of ZnO surge arresters is more highly sensitive and gives more linear response than the existing devices using the detection method of the third harmonic leakage currents. Therefore, the proposed leakage current monitoring device can be useful for predicting the defects and performance deterioration of ZnO surge arresters in power system applications

Arrest of cytoplasmic streaming induces algal proliferation in green paramecia.

Directory of Open Access Journals (Sweden)

Toshiyuki Takahashi

Full Text Available A green ciliate Paramecium bursaria, bearing several hundreds of endosymbiotic algae, demonstrates rotational microtubule-based cytoplasmic streaming, in which cytoplasmic granules and endosymbiotic algae flow in a constant direction. However, its physiological significance is still unknown. We investigated physiological roles of cytoplasmic streaming in P. bursaria through host cell cycle using video-microscopy. Here, we found that cytoplasmic streaming was arrested in dividing green paramecia and the endosymbiotic algae proliferated only during the arrest of cytoplasmic streaming. Interestingly, arrest of cytoplasmic streaming with pressure or a microtubule drug also induced proliferation of endosymbiotic algae independently of host cell cycle. Thus, cytoplasmic streaming may control the algal proliferation in P. bursaria. Furthermore, confocal microscopic observation revealed that a division septum was formed in the constricted area of a dividing paramecium, producing arrest of cytoplasmic streaming. This is a first report to suggest that cytoplasmic streaming controls proliferation of eukaryotic cells.

The relevance of crack arrest phenomena for pressure vessel structural integrity assessment

The potential role of a crack arrest argument for the structural integrity assessments of steel pressure vessels and the relationship between crack initiation and crack arrest philosophies are described. A typical structural integrity assessment using crack initiation fracture mechanics is illustrated by means of a case study based on assessment of the steel pressure vessels for Magnox power stations. Evidence of the occurrence of crack arrest in structures is presented and reviewed, and the applications to pressure vessels which are subjected to similar conditions are considered. An outline is given of the material characterisation that would be required to undertake a crack arrest integrity assessment. It is concluded that crack arrest arguments could be significant in the structural integrity assessment of PWR reactor pressure vessels under thermal shock conditions, whereas for Magnox steel pressure vessels it would be limited in its potential to supporting existing arguments.

Carbamazepine induces mitotic arrest in mammalian Vero cells

Perez Martin, J.M.; Fernandez Freire, P.; Labrador, V.; Hazen, M.J.

2008-01-01

We reported recently that the anticonvulsant drug carbamazepine, at supratherapeutic concentrations, exerts antiproliferative effects in mammalian Vero cells, but the underlying mechanism has not been elucidated. This motivates us to examine rigorously whether growth arrest was associated with structural changes in cellular organization during mitosis. In the present work, we found that exposure of the cells to carbamazepine led to an increase in mitotic index, mainly due to the sustained block at the metaphase/anaphase boundary, with the consequent inhibition of cell proliferation. Indirect immunofluorescence, using antibodies directed against spindle apparatus proteins, revealed that mitotic arrest was associated with formation of monopolar spindles, caused by impairment of centrosome separation. The final consequence of the spindle defects induced by carbamazepine, depended on the duration of cell cycle arrest. Following the time course of accumulation of metaphase and apoptotic cells during carbamazepine treatments, we observed a causative relationship between mitotic arrest and induction of cell death. Conversely, cells released from the block of metaphase by removal of the drug, continued to progress through mitosis and resume normal proliferation. Our results show that carbamazepine shares a common antiproliferative mechanism with spindle-targeted drugs and contribute to a better understanding of the cytostatic activity previously described in Vero cells. Additional studies are in progress to extend these initial findings that define a novel mode of action of carbamazepine in cultured mammalian cells

Full Text Available The objectives of this study were to measure the incidence and types of medication prescribing errors (MPEs in Iraqi hospitals, to calculate for the first time the percentage of physician agreement with pharmacist medication regimen review (MRR recommendations regarding MPEs, and to identify the factors influencing the physician agreement rate with these recommendations. Methods: Fourteen pharmacists (10 females and 4 males reviewed each hand-written physician order for 1506 patients who were admitted to two public hospitals in Al-Najaf, Iraq during August 2015. The pharmacists identified medication prescribing errors using the Medscape WebMD, LCC phone application as a reference. The pharmacists contacted the physicians (2 females and 34 males in-person to address MPEs that were identified. Results: The pharmacists identified 78 physician orders containing 99 MPEs with an incidence of 6.57 percent of all the physician orders reviewed. The patients with MPEs were taking 4.8 medications on average. The MPEs included drug-drug interactions (65.7%, incorrect doses (16.2%, unnecessary medications (8.1%, contra-indications (7.1%, incorrect drug duration (2%, and untreated conditions (1%. The physicians implemented 37 (37.4% pharmacist recommendations. Three factors were significantly related to physician acceptance of pharmacist recommendations. These were physician specialty, pharmacist gender, and patient gender. Pediatricians were less likely (OR= 0.1 to accept pharmacist recommendations compared to internal medicine physicians. Male pharmacists received more positive responses from physicians (OR=7.11 than female pharmacists. Lastly, the recommendations were significantly more likely to be accepted (OR= 3.72 when the patients were females. Conclusions: The incidence of MPEs is higher in Iraqi hospitalized patients than in the U.S. and U.K, but lower than in Brazil, Ethiopia, India, and Croatia. Drug-drug interactions were the most common type of

Pressurized thermal shock (PTS) is a phenomenon that can occur in the reactor pressure vessels (RPVs) with internal pressure and is one of the most severe stress conditions that can be applied to the vessel. Preliminary research has shown that no PTS concern is likely to exist on Japanese RPVs during their design service lives. However, public acceptance of vessel integrity requires analyses and experiment in order to establish an analytical method and a database for life extension of Japanese RPVs. The Japanese PTS integrity study was carried out from FY 1983 to FY 1991 as a national project by Japan Power Engineering and Inspection Corporation (JAPEIC) under contract with Ministry of International Trade and Industry (MITI) in cooperation with LWR utilities and vendors. Here, a crack arrest test was carried out using a toughness gradient steel plate with three layers to study the concept of crack arrest toughness. Four-point bending load with thermal shock was applied to the large flat plate specimen with a surface crack. Five crack initiations and arrests were observed during the test and the propagated crack bifurcated. Finally, cracks were arrested at the boundary of the first and the second layer, except for a small segment of the crack. The first crack initiation took place slightly higher than the lower bound of K Ic data obtained by ITCT specimens. That is, the K IC concept for brittle crack initiation was verified for heavy section steel plates. The first crack arrest took place within the scatter band of K Ia and K Id data for the first layer. That is, the K Ia concept appears applicable for crack arrest of a short crack jump

Full Text Available The communications in Iraq has been fluctuated for decades. In fact, this fluctuation constitutes a reality that the country has been facing such as the security issues, the economic blockade imposed on the previous regime, and all the exceptional circumstances. This paper illustrates the nature and reality of communication in Iraq after 2003. While the sophisticated technology works very well all around the world, Iraq still does not keep the work up to improve its communications. This paper tackles the most importantcommunication problems in Iraq after 2003, and the possibility to process good services to customers, either by developing the governmental combinations, or/and by enforcing telecommunication companies to provide their best services to their customers. This paper answers the following the questions: Are the telecom/communication companies serve good qualities to the customers? If not, why? Who is the responsible? Are these companies at least doing their best to serve good qualities? Or are they just profitable companies? Why have these companies not started using the optical fiber cables instead of the copper one? Is the government seeking to compel such companies to serve good services? Whether the Iraqi government plans to develop the landlines services so it would compete with the telecom companies? What is the role of the Communication and Media Commission (CMC?

Relationship between cardiopulmonary arrest and resuscitation (CPR) durations and survival after out-of-hospital cardiac arrest (OHCA) remain unclear. Our primary aim was to determine the association between survival without neurologic sequelae and cardiac arrest intervals in the setting of witnessed OHCA. We analyzed 27,301 non-traumatic, witnessed OHCA patients in France included in the national registry from June 1, 2011 through December 1, 2015. We analyzed cardiac arrest intervals, designated as no-flow (NF; from collapse to start of CPR) and low-flow (LF; from start of CPR to cessation of resuscitation) in relation to 30-day survival without sequelae. We determined the influence of recognized prognostic factors (age, gender, initial rhythm, location of cardiac arrest) on this relation. For the entire cohort, the area delimited by a value of NF greater than 12min (95% confidence interval: 11-13min) and LF greater than 33min (95% confidence interval: 29-45min), yielded a probability of 30-day survival of less than 1%. These sets of values were greatly influenced by initial cardiac arrest rhythm, age, sex and location of cardiac arrest. Extended CPR duration (greater than 40min) in the setting of initial shockable cardiac rhythm is associated with greater than 1% survival with NF less than 18min. The NF interval was highly influential on the LF interval regardless of outcome, whether return of spontaneous circulation (padvanced techniques. Copyright © 2016 Elsevier Ireland Ltd.

The objective of the Heavy-Section Steel Irradiation Program Sixth Irradiation Series is to determine the effect of neutron irradiation on the shift and shape of the lower-bound curve to crack-arrest toughness data. Two submerged-arc welds with copper contents of 0.23 and 0.31 wt % were commercially fabricated in 220-mm-thick plate. Crack-arrest specimens fabricated from these welds were irradiated at a nominal temperature of 288 degrees C to an average fluence of 1.9 x 10 19 neutrons/cm 2 (>1 MeV). This is the second report giving the results of the tests on irradiated duplex-type crack-arrest specimens. A previous report gave results of tests on irradiated weld-embrittled-type specimens. Charpy V-notch (CVN) specimens irradiated in the same capsules as the crack-arrest specimens were also tested, and a 41-J transition temperature shift was determined from these specimens. open-quotes Mean close-quote curves of the same form as the American Society of Mechanical Engineers (ASME) K la curve were fit to the data with only the open-quotes reference temperatureclose quotes as a parameter. The shift between the mean curves agrees well with the 41-J transition temperature shift obtained from the CVN specimen tests. Moreover, the four data points resulting from tests on the duplex crack-arrest specimens of the present study did not make a significant change to mean curve fits to either the previously obtained data or all the data combined

2014-03-01

Full Text Available The aim of the present study is to assess the complications of mild induced hypothermia (MIH in patients with cardiac arrest. Presently, based on the guidelines of the American heart Association, MIH following successful cardiopulmonary resuscitation (CPR in unconscious adult patients due to ventricular fibrillation (VF with out-of-hospital cardiac arrest (OOHCA is essential and required. However, MIH could be associated with complications in Patients with cardiac arrest. Studies conducted on the precautions and care following cardiac arrest and MIH were included. Valid scientific data bases were used for data collection. The obtained results from different studies revealed that mild MIH could be associated with numerous complications and the knowledge and awareness of the medical staff from the complications is required to guarantee successful therapeutic approaches in MIH following cardiac arrest which is a novel medical facility with different styles and complications. Overall, further future studies are required to improve the quality of MIH, to increase survival and to decrease complications rates.

Targeted temperature management is recommended for comatose adults and children after out-of-hospital cardiac arrest; however, data on temperature management after in-hospital cardiac arrest are limited. In a trial conducted at 37 children's hospitals, we compared two temperature interventions in children who had had in-hospital cardiac arrest. Within 6 hours after the return of circulation, comatose children older than 48 hours and younger than 18 years of age were randomly assigned to therapeutic hypothermia (target temperature, 33.0°C) or therapeutic normothermia (target temperature, 36.8°C). The primary efficacy outcome, survival at 12 months after cardiac arrest with a score of 70 or higher on the Vineland Adaptive Behavior Scales, second edition (VABS-II, on which scores range from 20 to 160, with higher scores indicating better function), was evaluated among patients who had had a VABS-II score of at least 70 before the cardiac arrest. The trial was terminated because of futility after 329 patients had undergone randomization. Among the 257 patients who had a VABS-II score of at least 70 before cardiac arrest and who could be evaluated, the rate of the primary efficacy outcome did not differ significantly between the hypothermia group and the normothermia group (36% [48 of 133 patients] and 39% [48 of 124 patients], respectively; relative risk, 0.92; 95% confidence interval [CI], 0.67 to 1.27; P=0.63). Among 317 patients who could be evaluated for change in neurobehavioral function, the change in VABS-II score from baseline to 12 months did not differ significantly between the groups (P=0.70). Among 327 patients who could be evaluated for 1-year survival, the rate of 1-year survival did not differ significantly between the hypothermia group and the normothermia group (49% [81 of 166 patients] and 46% [74 of 161 patients], respectively; relative risk, 1.07; 95% CI, 0.85 to 1.34; P=0.56).

Cardiac arrest during gamete release in chum salmon regulated by the parasympathetic nerve system.

Directory of Open Access Journals (Sweden)

Yuya Makiguchi

Full Text Available Cardiac arrest caused by startling stimuli, such as visual and vibration stimuli, has been reported in some animals and could be considered as an extraordinary case of bradycardia and defined as reversible missed heart beats. Variability of the heart rate is established as a balance between an autonomic system, namely cholinergic vagus inhibition, and excitatory adrenergic stimulation of neural and hormonal action in teleost. However, the cardiac arrest and its regulating nervous mechanism remain poorly understood. We show, by using electrocardiogram (ECG data loggers, that cardiac arrest occurs in chum salmon (Oncorhynchus keta at the moment of gamete release for 7.39+/-1.61 s in females and for 5.20+/-0.97 s in males. The increase in heart rate during spawning behavior relative to the background rate during the resting period suggests that cardiac arrest is a characteristic physiological phenomenon of the extraordinarily high heart rate during spawning behavior. The ECG morphological analysis showed a peaked and tall T-wave adjacent to the cardiac arrest, indicating an increase in potassium permeability in cardiac muscle cells, which would function to retard the cardiac action potential. Pharmacological studies showed that the cardiac arrest was abolished by injection of atropine, a muscarinic receptor antagonist, revealing that the cardiac arrest is a reflex response of the parasympathetic nerve system, although injection of sotalol, a beta-adrenergic antagonist, did not affect the cardiac arrest. We conclude that cardiac arrest during gamete release in spawning release in spawning chum salmon is a physiological reflex response controlled by the parasympathetic nervous system. This cardiac arrest represents a response to the gaping behavior that occurs at the moment of gamete release.

Iraqi western plateau is considered as one of the most resourceful areas of the middle east, that is not yet well explored, due to the many political disturbances and security issues. The viability of underground water for the various industrial, municipal, commercial and agricultural uses is examined for Shithatha, Karbala governorates as a representative for the western plateau via chemical and physical analysis of water samples that are taken from 9 wells and 3 springs all-around the study area during the wet and dry periods. Hydro chemical and statistical analysis for the field samples have proved that groundwater of the studied area is classified as slightly-brackish water and water hardness is very high. Also, the results of the analyses of trace elements in the groundwater of the study area have confirmed the contamination of groundwater with some elements such as (Fe, Cd, Pb, Ni) in concentrations that have exceeded the WHO and Iraqi national standards IQS, permissible limits. The application of Hydro-chemical formulae of Kurlouv and Piper, Schoeller, Stiff classifications have demonstrated that most samples of the study area have water type of (Na2SO4) while other samples have ranged between (MgSO4), and (NaCl) water type. The quality of groundwater is unsuitable for drinking and industrial purposes and it is almost suitable for irrigation purposes, but it is suitable for livestock, building and agricultural purposes because the salinity of the water is within the permissible limits when considering the nature of the soil.

Activation of a host DNA damage response (DDR) is essential for DNA replication of minute virus of canines (MVC), a member of the genus Bocavirus of the Parvoviridae family; however, the mechanism by which DDR contributes to viral DNA replication is unknown. In the current study, we demonstrate that MVC infection triggers the intra-S-phase arrest to slow down host cellular DNA replication and to recruit cellular DNA replication factors for viral DNA replication. The intra-S-phase arrest is regulated by ATM (ataxia telangiectasia-mutated kinase) signaling in a p53-independent manner. Moreover, we demonstrate that SMC1 (structural maintenance of chromosomes 1) is the key regulator of the intra-S-phase arrest induced during infection. Either knockdown of SMC1 or complementation with a dominant negative SMC1 mutant blocks both the intra-S-phase arrest and viral DNA replication. Finally, we show that the intra-S-phase arrest induced during MVC infection was caused neither by damaged host cellular DNA nor by viral proteins but by replicating viral genomes physically associated with the DNA damage sensor, the Mre11-Rad50-Nbs1 (MRN) complex. In conclusion, the feedback loop between MVC DNA replication and the intra-S-phase arrest is mediated by ATM-SMC1 signaling and plays a critical role in MVC DNA replication. Thus, our findings unravel the mechanism underlying DDR signaling-facilitated MVC DNA replication and demonstrate a novel strategy of DNA virus-host interaction. PMID:23365434

Optimizing Neurologically Intact Survival from Sudden Cardiac Arrest: A Call to Action

Directory of Open Access Journals (Sweden)

Jeffrey M. Goodloe

2014-11-01

Full Text Available The U.S. national out-of-hospital and in-hospital cardiac arrest survival rates, although improving recently, have remained suboptimal despite the collective efforts of individuals, communities, and professional societies. Only until very recently, and still with inconsistency, has focus been placed specifically on survival with pre-arrest neurologic function. The reality of current approaches to sudden cardiac arrest is that they are often lacking an integrative, multi-disciplinary approach, and without deserved funding and outcome analysis. In this manuscript, a multidisciplinary group of authors propose practice, process, technology, and policy initiatives to improve cardiac arrest survival with a focus on neurologic function.

So far, cardiac arrest is still associated with high mortality or severe neurological disability in survivors. At the tissue level, cardiac arrest results into an acute condition of generalized hypoxia. A better understanding of the pathophysiology of ischemia-reperfusion and of the inflammatory response that develops after cardiac arrest could help to design novel therapeutic strategies in the future. It seems unlikely that a single drug, acting as a , might be able to improve survival or neurological prognosis. Lessons learned from pathophysiological mechanisms rather indicate that combined therapies, involving thrombolysis, neuroprotective agents, antioxidants and anti-inflammatory molecules, together with temperature cooling, might represent helpful strategies to improve patient's outcome after cardiac arrest.

The variation of the SNPs in FTO (fat mass and obesity associated) gene are improved to be associated with obesity and type 2 diabetes (T2DM) in some ethnic groups for example in European while, this consistency is controversial in Asians and there were few studies in Iraqi population about the effect of this gene on the development of T2DM in obese patients. Therefore, the objective of this study is to investigate the impact of the two common FTO gene variants in the development of T2DM in obese Iraqi patients. A case-control study in which the FTO gene variants rs9939609 and rs17817449 were genotyping in a total of 800 individuals, 400 T2DM obese patients (patients group) and 400 healthy control obese volunteers (control group) to explore the relation of these SNPs with T2DM in obese Iraqi population. The patients group was enrolled from diabetic clinic in Al Najaf al Ashraf based on WHO guidelines of T2DM. From whole blood the DNA was extraction and genotyped by using ScaI and AlwNI enzymes respectively in the PCR-RFLP technique. Multinomial logistic regression was applied to compare the proportions of genotypes and alleles. The odd's ratio, t-test P value at 95% confidence interval were measured before and after adjustment of BMI, age and sex adjustment. The genetic power, Hardy Weinberg equilibrium and haplotype analysis were tested in the present study. It was observed that the presence of T allele in the two SNPs rs9939609 and rs17817449 in the FTO gene polymorphisms was associated with increased risk for the development of T2DM in Iraqi obese individuals. The minor allele (T) in rs9939609 was significantly higher (P=0.0001) in T2DM (31.25%) when compared with that of the control obese group (20%). The Homozygous genotype (TT) significantly (OR=3.25, CI 95% 1.87-5.64, P=0.000) increased the risk of T2DM by three folds with respect to those of wild type (AA) after adjustment for age, sex and BMI, furthermore, it was significantly increased the risk in the

Cell cycle arrest and cell survival induce reverse trends of cardiolipin remodeling.

Directory of Open Access Journals (Sweden)

Yu-Jen Chao

Full Text Available Cell survival from the arrested state can be a cause of the cancer recurrence. Transition from the arrest state to the growth state is highly regulated by mitochondrial activity, which is related to the lipid compositions of the mitochondrial membrane. Cardiolipin is a critical phospholipid for the mitochondrial integrity and functions. We examined the changes of cardiolipin species by LC-MS in the transition between cell cycle arrest and cell reviving in HT1080 fibrosarcoma cells. We have identified 41 cardiolipin species by MS/MS and semi-quantitated them to analyze the detailed changes of cardiolipin species. The mass spectra of cardiolipin with the same carbon number form an envelope, and the C64, C66, C68, C70 C72 and C74 envelopes in HT1080 cells show a normal distribution in the full scan mass spectrum. The cardiolipin quantity in a cell decreases while entering the cell cycle arrest, but maintains at a similar level through cell survival. While cells awakening from the arrested state and preparing itself for replication, the groups with short acyl chains, such as C64, C66 and C68 show a decrease of cardiolipin percentage, but the groups with long acyl chains, such as C70 and C72 display an increase of cardiolipin percentage. Interestingly, the trends of the cardiolipin species changes during the arresting state are completely opposite to cell growing state. Our results indicate that the cardiolipin species shift from the short chain to long chain cardiolipin during the transition from cell cycle arrest to cell progression.

The rate of survival from out-of-hospital cardiac arrest in Europe remains unacceptably low and could be increased by better bystander cardiopulmonary resuscitation (CPR) rates. The European Resuscitation Council has announced that there will be a European Cardiac Arrest Awareness Day every year on the 16th of October. This is to coincide with the goals of the Written Declaration passed by the European Parliament in June 2012 that emphasised the importance of equal access to CPR and automated external defibrillator (AED) training. The topic of this year's Awareness Day is 'Children Saving Lives' and it is hoped that all national resuscitation councils will promote awareness of the benefits of training all children in CPR and AED use and lobby for legislative change to ensure that all children receive this training. Children are not just the adults of tomorrow - they are the lifesavers of today and tomorrow. Copyright © 2013 Elsevier Ltd. All rights reserved.

Effect of gamma irradiation on the sugar and protein composition of Iraqi dates

Auda, H.; Khalaf, Z.; Mirjan, J.

1978-01-01

Completely ripened date fruits of several Iraqi varieties were irradiated with 30, 70, 100, 270 and 500krad of gamma irradiation and stored at a temperature of 25-35 0 C in wooden boxes or in plastic bags. At various intervals samples were taken and analysed by paper-chromatography, gas-chromatography and spectrophotometry for quantitative and qualitative changes in carbohydrates. The results showed no effect of gamma irradiation on reducing sugar and major carbohydrate components. The formation of malonaldehyde under gamma irradiation of dates and solid standard sugars was also studied up to 500krad. The results showed no formation of malonaldehyde in irradiated date samples as well as standard sugars. Gamma irradiation showed no effect on the protein content of dates. However, storage showed some reduction in the protein content of both unirradiated and irradiated samples. (author)

Everyday discrimination contributes negatively to depressive symptomatology among Blacks in the US and being arrested could add to this depression. Using data from the National Survey on American Life, the present study determined the association between an arrest history and major depressive disorder (MDD), while accounting for discrimination among African Americans, US-born Afro-Caribbeans and first-generation Black immigrants. Findings from logistic regression analyses adjusted for discrimination suggested an arrest history is associated with 12-month MDD (Adjusted OR=1.47; 95% CI=1.02-2.10) and lifetime MDD (Adjusted OR=1.56 CI=1.17-2.09). Accounting for drug and alcohol dependence attenuated the association between arrest history and 12-month MDD, but not lifetime MDD. The associations between arrest history and both 12-month and lifetime MDD, and discrimination and lifetime MDD varied by ethnic/immigrant group. Specifically, while the association between arrest history and MDD (both 12-month and lifetime) was strongest among US-born Afro-Caribbeans, evidence consistent with the immigrant paradox, the association between discrimination and lifetime MDD was particularly relevant for first-generation Black immigrants, suggesting discrimination may hinder the protection of first-generation status. Mental health prevention and treatment programs should target the stress associated with being arrested and experiencing discrimination among US Blacks. Copyright © 2014 Elsevier Ireland Ltd.

Arrest of metamorphosis induced by x rays in flesh fly, Sarcophaga peregrina

International Nuclear Information System (INIS)

Sasaki, S.; Sakka, M.

1976-01-01

Arrest of metamorphosis induced by x irradiation at prepupal stage was studied histologically, and age dependency of radiosensitivity with regard to this effect was examined. Prepupae did not cease their development soon after irradiation, but continued to develop and evaginated the head and the thorax. At this point, development came to a stop. In these animals, not only the histogenesis of imaginal tissues but also the histolysis of larval tissues was arrested. Since the arrest of development was not observed after irradiation at the pupal stage, the effect was considered to result from inhibition of initiation of postpupation development. A possible mechanism of the arrest of postpupation development in the irradiated animals was discussed in connection with the neuroendocrine control of insect development

Introduction Out-of-hospital cardiac arrest (OHCA) is a major public health problem. Recognising the complexity of the underlying causes of OHCA in the community, we aimed to establish the clinical, pharmacological, environmental and genetic factors and their interactions that may cause OHCA. Methods and analysis We set up a large-scale prospective community-based registry (AmsteRdam Resuscitation Studies, ARREST) in which we prospectively include all resuscitation attempts from OHCA in a large study region in the Netherlands in collaboration with Emergency Medical Services. Of all OHCA victims since June 2005, we prospectively collect medical history (through hospital and general practitioner), and current and previous medication use (through community pharmacy). In addition, we include DNA samples from OHCA victims with documented ventricular tachycardia/fibrillation during the resuscitation attempt since July 2007. Various study designs are employed to analyse the data of the ARREST registry, including case–control, cohort, case only and case-cross over designs. Ethics and dissemination We describe the rationale, outline and potential results of the ARREST registry. The design allows for a stable and reliable collection of multiple determinants of OHCA, while assuring that the patient, lay-caregiver or medical professional is not hindered in any way. Such comprehensive data collection is required to unravel the complex basis of OHCA. Results will be published in peer-reviewed journals and presented at relevant scientific symposia. PMID:25332818

Arrested embryonic development: a review of strategies to delay hatching in egg-laying reptiles

Science.gov (United States)

Rafferty, Anthony R.; Reina, Richard D.

2012-01-01

Arrested embryonic development involves the downregulation or cessation of active cell division and metabolic activity, and the capability of an animal to arrest embryonic development results in temporal plasticity of the duration of embryonic period. Arrested embryonic development is an important reproductive strategy for egg-laying animals that provide no parental care after oviposition. In this review, we discuss each type of embryonic developmental arrest used by oviparous reptiles. Environmental pressures that might have directed the evolution of arrest are addressed and we present previously undiscussed environmentally dependent physiological processes that may occur in the egg to bring about arrest. Areas for future research are proposed to clarify how ecology affects the phenotype of developing embryos. We hypothesize that oviparous reptilian mothers are capable of providing their embryos with a level of phenotypic adaptation to local environmental conditions by incorporating maternal factors into the internal environment of the egg that result in different levels of developmental sensitivity to environmental conditions after they are laid.

To evaluate controlled substance prescribing trends available in the Maine Prescription Monitoring Program (PMP) among individuals arrested for prescription drug "trafficking." The demographic characteristics of the individuals who had matching prescription records in the PMP within 90 days of the arrest were identified. A population-based, retrospective cohort study using data from the Maine Diversion Alert Program (DAP) and the Maine PMP. The study population consisted of persons arrested for trafficking prescription drugs in Maine during the 2014 calendar year from January 1 to December 31. There were 594 trafficking arrests reported by the Maine DAP in 2014. The study population consisted of the 235 persons (40%) with arrests involving controlled prescription medications. The mean age of these persons was 33 years (range 18-77 yrs), and 156 (66%) were male. Arrests involved 154 prescription opioids (65%), seven stimulants (3%), seven benzodiazepines (3%), and 77 unspecified controlled prescription drugs (33%). A minority of individuals (n=57, 24%) had a prescription record in the PMP that matched the substance involved in the arrest. Only one person with matching PMP and arrest records utilized ≥ 5 prescribers, while none used ≥ 5 pharmacies within 90 days before the arrest. Payment methods for matching prescriptions were commercial insurance (n=28, 49%), Medicaid (n=19, 33%), Medicare (n=5, 9%), and cash (n=5, 9%). The majority (76%) of persons arrested for prescription drug trafficking did not have PMP records and did not directly obtain the diverted medication from a licensed pharmacy. Traditional red flags, like cash payment and using multiple prescribers or pharmacies, were uncommon. Therefore, arrest records for diversion and PMPs are distinct and complementary tools for identifying individuals at risk for substance misuse. © 2016 Pharmacotherapy Publications, Inc.

Full Text Available Non-state armed groups are the main threats to states’ national security in the 21st century, to defend against which, states require useful methods. Recently, use of children by these groups, especially in the Middle East, has turned into one of the most important discussable issues that need to be evaluated in the context of the law of armed conflict. This study aims to discuss legal regime of the military use of children in armed conflict. The main purpose of the study is to analyze the use of child soldiers by the Syrian-Iraqi Salafi-Jihadist Group in its combat operations. In this respect, initially, the legal definition of child soldiers and the role of them in armed conflicts will be discussed. Based on this, different forms of the child soldiers’ involvement in armed conflicts and the international criminal responsibility for their war crimes will be examined as an applicable law in the context of international criminal law.

A study was conducted to evaluate new and laboratory-aged samples of surge arresters and anchorage polymeric insulators, for 12 and 24 kV networks, which are used by the Rio Grande Energia (RGE). Power utility polymeric compounds were analyzed by Differential Scanning Calorimetry (DSC), Thermogravimetric Analysis (TG), Dynamic-Mechanic Analysis (DMA), Fourier Transformed Infrared Spectroscopy (FTIR) and Scanning Electronic Microscopy (SEM) to verify changes in the insulator properties due to degradation occurred during the experiments. The analyses were carried out before and after 6 months of aging in laboratory devices (weather meter, 120 deg C, salt spray, immersion in water). After the aging experiments, high-voltage electrical tests were also conducted: a radio interference voltage test and, simultaneously, the total and the internal leakage currents were measured to verify the surface degradation of the polymeric material used in the housing. The impulse current test was applied with current values close to 5, 10 and 30 k A, in order to force an internal degradation. Results showed that only surface degradation is detected at the polymer. The main properties of the parts were not affected by the aging. It confirms that polymer insulator and surge arrester are appropriate for use in electricity distribution networks. (author)

Local stresses, dyke arrest and surface deformation in volcanic edificesand rift zones

Directory of Open Access Journals (Sweden)

L. S. Brenner

2004-06-01

Full Text Available Field studies indicate that nearly all eruptions in volcanic edifices and rift zones are supplied with magma through fractures (dykes that are opened by magmatic overpressure. While (inferred dyke injections are frequent during unrest periods, volcanic eruptions are, in comparison, infrequent, suggesting that most dykes become arrested at certain depths in the crust, in agreement with field studies. The frequency of dyke arrest can be partly explained by the numerical models presented here which indicate that volcanic edifices and rift zones consisting of rocks of contrasting mechanical properties, such as soft pyroclastic layers and stiff lava flows, commonly develop local stress fields that encourage dyke arrest. During unrest, surface deformation studies are routinely used to infer the geometries of arrested dykes, and some models (using homogeneous, isotropic half-spaces infer large grabens to be induced by such dykes. Our results, however, show that the dyke-tip tensile stresses are normally much greater than the induced surface stresses, making it difficult to explain how a dyke can induce surface stresses in excess of the tensile (or shear strength while the same strength is not exceeded at the (arrested dyke tip. Also, arrested dyke tips in eroded or active rift zones are normally not associated with dyke-induced grabens or normal faults, and some dykes arrested within a few metres of the surface do not generate faults or grabens. The numerical models show that abrupt changes in Young's moduli(stiffnesses, layers with relatively high dyke-normal compressive stresses (stress barriers, and weak horizontal contacts may make the dyke-induced surface tensile stresses too small for significant fault or graben formation to occur in rift zones or volcanic edifices. Also, these small surface stresses may have no simple relation to the dyke geometry or the depth to its tip. Thus, for a layered crust with weak contacts, straightforward

The correct and adequate modelling of ZnO surge arresters characteristics is very important for insulation coordination studies and systems reliability. In this context many researchers addressed considerable efforts to the development of surge arresters models to reproduce the dynamic characteristics observed in their behaviour when subjected to fast front impulse currents. The difficulties with these models reside essentially in the calculation and the adjustment of their parameters. This paper proposes a new technique based on genetic algorithm to obtain the best possible series of parameter values of ZnO surge arresters models. The validity of the predicted parameters is then checked by comparing the predicted results with the experimental results available in the literature. Using the ATP-EMTP package, an application of the arrester model on network system studies is presented and discussed. (author)

To compare the effectiveness of three applications of silver diammine fluoride (SDF) solution at yearly interval and three applications of SDF solution or sodium fluoride (NaF) varnish at weekly interval at baseline in arresting active caries in the primary teeth of preschool children. Children aged 3-4 years (n = 371) who had at least one active caries lesion (ICDAS codes 3-6) in their primary teeth were randomly allocated into three groups: Group 1 - annual application of 30% SDF solution; Group 2 - three applications of 30% SDF at weekly intervals; and Group 3 - three applications of 5% NaF varnish at weekly intervals. Follow-up examinations were performed every 6 mo nths by the same masked examiner. After 30 months, 309 (83%) children with 1877 caries lesions remained in the study. For cavitated lesions (ICDAS code 5 or 6), the caries arrest rate of Group 1 (48%) was significantly higher than those of Group 2 (33%) and Group 3 (34%), (p  0.05). Presence of plaque on caries lesion, tooth type and tooth surface type had an influence on caries arrest. Over a 30-month period, annual applications of SDF solution is more effective than three weekly applications of NaF varnish or SDF solution at baseline in arresting active cavitated dentine caries lesions in primary teeth. As annual application of SDF solution was found to be more effective than 3 weekly applications of NaF varnish or SDF solution at baseline in arresting active cavitated dentine caries lesions, the former application protocol is preferred for young children who are available for regular caries arrest treatment.

Cardiac arrest is a catastrophic event that may arise during the management of convulsive status epilepticus. We aimed to report the clinical characteristics, outcomes, and early predictors of convulsive status epilepticus-related cardiac arrest. Retrospective multicenter study. Seventeen university or university affiliated participating ICUs in France and Belgium. Consecutive patients admitted to the participating ICUs for management of successfully resuscitated out-of-hospital cardiac arrest complicating the initial management of convulsive status epilepticus between 2000 and 2015. Patients were compared with controls without cardiac arrest identified in a single-center registry of convulsive status epilepticus patients, regarding characteristics, management, and outcome. None. We included 49 cases with convulsive status epilepticus-cardiac arrest and 235 controls. In the cases, median time from medical team arrival to cardiac arrest was 25 minutes (interquartile range, 5-85 min). First recorded rhythm was asystole in 25 patients (51%) and pulseless electrical activity in 13 patients (27%). A significantly larger proportion of patients had a favorable 1-year outcome (Glasgow Outcome Scale score of 5) among controls (90/235; 38%) than among cases (10/49; 21%; p = 0.02). By multivariate analysis, independent predictors of cardiac arrest were pulse oximetry less than 97% on scene (odds ratio, 2.66; 95% CI, 1.03-7.26; p = 0.04), drug poisoning as the cause of convulsive status epilepticus (odds ratio, 4.13; 95% CI, 1.27-13.53; p = 0.02), and complications during early management (odds ratio, 11.98; 95% CI, 4.67-34.69; p status epilepticus, relative hypoxemia, on-scene management complications, and drug poisoning as the cause of convulsive status epilepticus were strong early predictors of cardiac arrest, suggesting areas for improvement.

Powell's optimization method has been used for the evaluation of the surge arrester models parameters. The proper modelling of metal-oxide surge arresters and the right selection of equivalent circuit parameters are very significant issues, since quality and reliability of lightning performance studies can be improved with the more efficient representation of the arresters' dynamic behavior. The proposed approach selects optimum arrester model equivalent circuit parameter values, minimizing the error between the simulated peak residual voltage value and this given by the manufacturer. Application of the method in performed on a 120 kV metal oxide arrester. The use of the obtained optimum parameter values reduces significantly the relative error between the simulated and manufacturer's peak residual voltage value, presenting the effectiveness of the method.

Metal Oxide Arrester (MOA) suffers from aging and poor insulation due to long-term impulse voltage and environmental impact, and the value and variation tendency of resistive current can reflect the health conditions of MOA. The common wired MOA detection need to use long cables, which is complicated to operate, and that wireless measurement methods are facing the problems of poor data synchronization and instability. Therefore a novel synchronous measurement system of arrester current resistive based on heterogeneous network is proposed, which simplifies the calculation process and improves synchronization, accuracy and stability and of the measuring system. This system combines LoRa wireless network, high speed wireless personal area network and the process layer communication, and realizes the detection of arrester working condition. Field test data shows that the system has the characteristics of high accuracy, strong anti-interference ability and good synchronization, which plays an important role in ensuring the stable operation of the power grid.

Crack arrest toughness measurements with A533B steel

International Nuclear Information System (INIS)

Salonen, Seppo.

1979-11-01

This work covers crack arrest toughness measurements on A533B steel done at the Technical Research Centre of Finland. These measurements are one part of a multinational effort, involving 30 laboratories. The aim of the cooperative test program is to examine two test procedures for measuring the crack arrest toughness, to give information about their reproducibility, and to identify the factors affecting the interpretation. The principles given for the testing were easy to apply in general and the results were satisfactory. Some factors in the test runs and in the specimen's behaviour are indicated which can cause error in the results or make implementation of the test more difficult. By comparing the results from our laboratory with average values from the test program a good agreement can be seen. Crack arrest toughness values derived from the compared procedures with a static analysis agree closely, but values calculated using a dynamic analysis differ considerably. (author)

Protective head-cooling during cardiac arrest and cardiopulmonary resuscitation: the original animal studies

Directory of Open Access Journals (Sweden)

Eric W. Brader

2010-02-01

Full Text Available Prolonged standard cardiopulmonary resuscitation (CPR does not reliably sustain brain viability during cardiac arrest. Pre-hospital adjuncts to standard CPR are needed in order to improve outcomes. A preliminary dog study demonstrated that surface cooling of the head during arrest and CPR can achieve protective levels of brain hypothermia (30°C within 10 minutes. We hypothesized that protective head-cooling during cardiac arrest and CPR improves neurological outcomes. Twelve dogs under light ketamine-halothane-nitrous oxide anesthesia were arrested by transthoracic fibrillation. The treated group consisted of six dogs whose shaven heads were moistened with saline and packed in ice immediately after confirmation of ventricular fibrillation. Six control dogs remained at room temperature. All 12 dogs were subjected to four minutes of ventricular fibrillation and 20 minutes of standard CPR. Spontaneous circulation was restored with drugs and countershocks. Intensive care was provided for five hours post-arrest and the animals were observed for 24 hours. In both groups, five of the six dogs had spontaneous circulation restored. After three hours, mean neurological deficit was significantly lower in the treated group (P=0.016, with head-cooled dogs averaging 37% and the normothermic dogs 62%. Two of the six head-cooled dogs survived 24 hours with neurological deficits of 9% and 0%, respectively. None of the control group dogs survived 24 hours. We concluded that head-cooling attenuates brain injury during cardiac arrest with prolonged CPR. We review the literature related to the use of hypothermia following cardiac arrest and discuss some promising approaches for the pre-hospital setting.

Progress toward national estimates of police use of force

Garner, Joel H.; Malega, Ronald W.; Maxwell, Christopher D.

2018-01-01

This research builds on three decades of effort to produce national estimates of the amount and rate of force used by law enforcement officers in the United States. Prior efforts to produce national estimates have suffered from poor and inconsistent measurements of force, small and unrepresentative samples, low survey and/or item response rates, and disparate reporting of rates of force. The present study employs data from a nationally representative survey of state and local law enforcement agencies that has a high survey response rate as well as a relatively high rate of reporting uses of force. Using data on arrests for violent offenses and the number of sworn officers to impute missing data on uses of force, we estimate a total of 337,590 use of physical force incidents among State and local law enforcement agencies during 2012 with a 95 percent confidence interval of +/- 10,470 incidents or +/- 3.1 percent. This article reports the extent to which the number and rate of force incidents vary by the type and size of law enforcement agencies. Our findings demonstrate the willingness of a large proportion of law enforcement agencies to voluntarily report the amount of force used by their officers and the relative strengths and weaknesses of the Law Enforcement Management and Administrative Statistics (LEMAS) program to produce nationally representative information about police behavior.

1983-07-06

Recent Supreme Court decisions, which interpret the 200-year-old Fourth Amendment of the US Constitution, are used to provide a brief overview of some search and seizure subjects important to management and officers responsible for physical protection of nuclear facilities. The overview is framed in practical terms in order to make the comments applicable to the everyday activity of nuclear-protective-force persons. The Supreme Court has described several exceptions where searches and seizures (arrests) are permitted without a warrant, despite the Fourth Amendment which states that warrants are always required. The seven exceptions briefly discussed are search incidents to a lawful arrest, the automobile-search exception, the suitcase or container exception, the hot-pursuit or emergency exception, the stop-and-frisk exception, the plain-view exception, and consent to be searched.

The ATM signaling cascade promotes recombination-dependent pachytene arrest in mouse spermatocytes.

Directory of Open Access Journals (Sweden)

Sarai Pacheco

2015-03-01

Full Text Available Most mutations that compromise meiotic recombination or synapsis in mouse spermatocytes result in arrest and apoptosis at the pachytene stage of the first meiotic prophase. Two main mechanisms are thought to trigger arrest: one independent of the double-strand breaks (DSBs that initiate meiotic recombination, and another activated by persistent recombination intermediates. Mechanisms underlying the recombination-dependent arrest response are not well understood, so we sought to identify factors involved by examining mutants deficient for TRIP13, a conserved AAA+ ATPase required for the completion of meiotic DSB repair. We find that spermatocytes with a hypomorphic Trip13 mutation (Trip13mod/mod arrest with features characteristic of early pachynema in wild type, namely, fully synapsed chromosomes without incorporation of the histone variant H1t into chromatin. These cells then undergo apoptosis, possibly in response to the arrest or in response to a defect in sex body formation. However, TRIP13-deficient cells that additionally lack the DSB-responsive kinase ATM progress further, reaching an H1t-positive stage (i.e., similar to mid/late pachynema in wild type despite the presence of unrepaired DSBs. TRIP13-deficient spermatocytes also progress to an H1t-positive stage if ATM activity is attenuated by hypomorphic mutations in Mre11 or Nbs1 or by elimination of the ATM-effector kinase CHK2. These mutant backgrounds nonetheless experience an apoptotic block to further spermatogenic progression, most likely caused by failure to form a sex body. DSB numbers are elevated in Mre11 and Nbs1 hypomorphs but not Chk2 mutants, thus delineating genetic requirements for the ATM-dependent negative feedback loop that regulates DSB numbers. The findings demonstrate for the first time that ATM-dependent signaling enforces the normal pachytene response to persistent recombination intermediates. Our work supports the conclusion that recombination defects trigger

Iraqi, Syrian, and Palestinian Refugee Adolescents' Beliefs About Parental Authority Legitimacy and Its Correlates.

Smetana, Judith G; Ahmad, Ikhlas; Wray-Lake, Laura

2015-01-01

This study examined intra- and interindividual variations in parental legitimacy beliefs in a sample of 883 Arab refugee adolescents (M(age) = 15.01 years, SD = 1.60), 277 Iraqis, 275 Syrians, and 331 Palestinians in Amman, Jordan. Confirmatory factor analyses showed distinct latent factors for moral-conventional, prudential, and personal legitimacy items. Older adolescents rated legitimacy lower for personal issues, but higher for prudential issues. Beliefs were associated with socioeconomic status (fathers' education, family size), particularly for personal issues, but were more pervasively associated with displacement-related experiences. Greater war trauma was associated with less prudential legitimacy for all youth and more authority legitimacy over moral-conventional issues for Syrian youth. Greater hopefulness was associated with more authority legitimacy over all but personal issues. © 2015 The Authors. Child Development © 2015 Society for Research in Child Development, Inc.

The Force-Displacement Relationship in Commonly Used Resuscitation Manikins: Not Very Human

Master curve based correlation between static initiation toughness KIC and crack arrest toughness KIa

International Nuclear Information System (INIS)

Wallin, K.; Rintamaa, R.

1999-01-01

Historically the ASME reference curve concept assumes a constant relation between static fracture toughness initiation toughness and crack arrest toughness. In reality, this is not the case. Experimental results show that the difference between K IC and K Ia is material specific. For some materials there is a big difference while for others they nearly coincide. So far, however, no systematic study regarding a possible correlation between the two parameters has been performed. The recent Master curve method, developed for brittle fracture initiation estimation, has enabled a consistent analysis of fracture initiation toughness data. The Master curve method has been modified to be able to describe also crack arrest toughness. Here, this modified 'crack arrest master curve' is further validated and used to develop a simple, but yet (for safety assessment purpose) adequately accurate correlation between the two fracture toughness parameters. The correlation enables the estimation of crack arrest toughness from small Charpy-sized static fracture toughness tests. The correlation is valid for low Nickel steels ≤ (1.2% Ni). If a more accurate description of the crack arrest toughness is required, it can either be measured experimentally or estimated from instrumented Charpy-V crack arrest load information. (orig.)

Ly, Tony; Endo, Aki; Lamond, Angus I

2015-01-02

Previously, we analyzed protein abundance changes across a 'minimally perturbed' cell cycle by using centrifugal elutriation to differentially enrich distinct cell cycle phases in human NB4 cells (Ly et al., 2014). In this study, we compare data from elutriated cells with NB4 cells arrested at comparable phases using serum starvation, hydroxyurea, or RO-3306. While elutriated and arrested cells have similar patterns of DNA content and cyclin expression, a large fraction of the proteome changes detected in arrested cells are found to reflect arrest-specific responses (i.e., starvation, DNA damage, CDK1 inhibition), rather than physiological cell cycle regulation. For example, we show most cells arrested in G2 by CDK1 inhibition express abnormally high levels of replication and origin licensing factors and are likely poised for genome re-replication. The protein data are available in the Encyclopedia of Proteome Dynamics (

Advanced cardiovascular life support guidelines exist, yet there are variations in clinical practice. Our study aims to describe the utilization of medications during resuscitation from in-hospital cardiopulmonary arrest. A retrospective review of patients who suffered a cardiopulmonary arrest from May 2008 to June 2014 was performed. Clinical and resuscitation data, including timing and dose of medications used, were extracted from the electronic medical record and comparisons made. A total of 94 patients were included in the study. Patients were divided into different groups based on the medication combination used during resuscitation: (1) epinephrine; (2) epinephrine and bicarbonate; (3) epinephrine, bicarbonate, and calcium; (4) epinephrine, bicarbonate, and epinephrine drip; and (5) epinephrine, bicarbonate, calcium, and epinephrine drip. No difference in baseline demographics or clinical data was present, apart from history of dementia and the use of calcium channel blockers. The number of medications given was correlated with resuscitation duration (Spearman's rank correlation = 0.50, p resuscitation durations compared to that of the other groups (p resuscitation efforts for in-hospital cardiopulmonary arrests. Increased duration and mortality rates were found in those resuscitations compared with epinephrine alone, likely due to the longer resuscitation duration in the former groups.

We aimed to determine whether there is a seasonal variation of out-of-hospital cardiac arrests (OHCA) in an equatorial climate, which does not experience seasonal environmental change. We conducted an observational prospective study looking at the occurrence of OHCA in Singapore. Included were all patients with OHCA presented to Emergency Departments across the country. We examined the monthly, daily, and hourly number of cases over a three-year period. Data was analyzed using analysis of variance (ANOVA). From October, 1st 2001 to October, 14th 2004, 2428 patients were enrolled in the study. Mean age for cardiac arrests was 60.6 years with 68.0% male. Ethnic distribution was 69.5% Chinese, 15.0% Malay, 11.0% Indian, and 4.4% Others. There was no significant seasonal variation (spring/summer/fall/winter) of events (ANOVA P = 0.71), monthly variation (P = 0.88) or yearly variation (P = 0.26). We did find weekly peaks on Mondays and a circadian pattern with daily peaks from 9-10 am. We did not find any discernable seasonal pattern of cardiac arrests. This contrasts with findings from temperate countries and suggests a climatic influence on cardiac arrest occurrence. We also found that sudden cardiac arrests follow a circadian pattern.

A METHOD OF DETERMINING THE ABILITY OF THE ARRESTER TO ABSORB ENERGY WITHOUT BREAKING THE HEAT BALANCE

2015-08-01

Full Text Available Purpose.The aim of this study is to obtain a method for determining the capacity surge arrester nonlinear absorb energy without breaking the heat balance in modes of long-term application of operating voltage, which allows for analysis of their work in terms of violations as electricity. Methodology. For values of the energy passing through the arrester must be able to determine the current value for the voltage value in the area of leakage current-voltage characteristics. We have carried out calculations of the energy passing everywhere arrester for certain periods of time based on the current-voltage characteristics obtained experimentally. Analysis of the experimental current-voltage characteristics of resistors and literature led to the important conclusion that the dielectric properties of the ceramic varistor affect the value of active power losses in the arrester only when the active component of the leakage current is very small. This is confirmed by the characteristics of different classes of varistor voltage. This property of varistors and surge arresters shows the need to consider how the dielectric and conductive properties of the varistor ceramics in the analysis of work in the area of the arrester leakage current-voltage characteristic. These results demonstrate the need to clarify the mathematical model and the method for determining the energy dissipates in the area of the arrester leakage current CVC with their account. Results. The study, an improved mathematical model for calculating energy affects surge arrester during its working life. The study obtained the method, of evaluation capacity surge arrester, maintains heat balance throughout working life. Based on experimentally obtained current-voltage characteristic of the varistors is defined voltage at which surge arrester starts conducting active current. This allowed to receive specified mathematical model for calculating energy affects surge arrester and develop a method

A case of complete maternal and fetal recovery after prolonged cardiac arrest from massive lidocaine overdose is presented. A 27-year-old woman at 15 weeks gestation had a complete neurologic recovery after 22 minutes of CPR, including 19 minutes of electromechanical dissociation and asystole, with normal fetal heart function and fetal motion confirmed by ultrasound immediately after resuscitation. The patient delivered a healthy and neurologically normal infant at 40 weeks gestation. This is the longest cardiac arrest in early pregnancy reported in the medical literature with normal maternal and fetal outcome.

The objective of this study was to determine whether perceived health status of Iraqi immigrants and refugees residing in the United States was related to pre-migration environmental stress, current unemployment, and if they had emigrated before or after the 1991 Gulf War. A random sample of Iraqis residing in Southeast Michigan, US, was interviewed using an Arab language structured survey. The main outcome measure was self-rated health (SRH). Major predictors included socioeconomics, employment status, pre-migration environmental stress, and health disorders. Path analysis was used to look at mediating effects between predictors and SRH. We found that SRH was significantly worse among participants that had left Iraq after the 1991 Gulf War. Unemployment and environmental stress exposure were inversely related to SRH. There was a direct path between Gulf War exposure and poor health. In addition, there were indirect paths mediated through psychosomatic and psychiatric disorders to SRH. Another path went from Gulf War exposure, via environmental stress and somatic health to poor health. Unemployment had a direct path, as well as indirect paths mediated through psychiatric and psychosomatic disorders, to poor self-rated health. In conclusion, these results suggest that pre- as well as post-migration factors, and period of migration, affect health.

Full Text Available Patients with β-thalassemia may have an increased risk for diabetes mellitus and cardiovascular diseases due to high level of iron which may lead to insulin resistanceand metabolic syndrome. So this study aimed to evaluate the levels of lipids profile in Iraqi female patients with β-thalassemia. Forty twofemale (age 15-30 years were enrolled in this study. Blood was collected and the sera were separated from (22 female patients with β-thalassemia who were attended the Ibn-Al-Baladi hospital from September 2012 to January 2013 and (20 healthy subject as a control group. Body mass index (BMI, lipid profile, FSG, insulin, insulin resistance, insulin sensitivity, B-cell function, iron, atherogenic index of serum were estimated. The results showed the presence of a significant increase in serum iron and significant decrease in insulin, B-cell function, LDL, VLDL, and TC in serum of patients with β-thalassemia when compared with control group. BMI also showed a significant decrease in patients when compared with the controls. Serum Insulin resistance, insulin sensitivity, HDL, TG, AIS, and FSG showed no-significant differences in patients with β-thalassemia when compared with control group. We concluded there was no metabolic syndrome in female patients with β-thalassemia.

Radiation-induced G/sub 2/-arrest is reduced by inhibitors of poly(adenosine diphosphoribose) synthetase

Rowley, R.

1985-01-01

Experiments are in progress to test whether poly(adenosine diphosphoribose) synthesis is required for the induction of G/sub 2/-arrest in growing mammalian cells following X-irradiation. A variety of poly(ADPR) synthetase inhibitors have been tested to determine: 1) whether addition of an inhibitor to X-irradiated CHO cells reduces G/sub 2/-arrest; 2) whether compounds structurally similar to poly-(ADPR) synthetase inhibitors but inactive against this enzyme affect radiation-induced G/sub 2/-arrest and 3) whether the concentration dependence for poly(ADPR) synthetase inhibition matches that for G/sub 2/-arrest reduction. G/sub 2/-arrest was measured in X-irradiated (1.5 Gy) CHO cells using the mitotic cell selection technique. Poly(ADPR) synthetase activity was measured in permeabilized cells by /sup 3/H-NAD incorporation. The synthetase inhibitors used were 3-aminobenzamide, benzamide, nicotinamide, 4-acetyl pyridine, caffeine and theophylline. The inactive compounds used were 3-aminobenzoic acid, benzoic acid, nicotinic acid, adenine, adenosine and 3'-deoxyadenosine. Inhibitors of poly(ADPR) synthetase reduced G/sub 2/-arrest while related compounds which produced no enzyme inhibition did not. The concentration dependencies for G/sub 2/-arrest reduction and enzyme inhibition were similar only for methyl xanthines. Further analysis awaits the determination of intracellular drug concentrations

Cusick, Gretchen Ruth; Havlicek, Judy R.; Courtney, Mark E.

2012-01-01

This study examines a sample of foster youth at the onset of the transition to adulthood and explores how social bonds are related to the risk of arrest during adulthood. Drawing from official arrest records, event history models are used to examine the time to arrest. Because individuals may be at risk for different types of crime, competing risk regression models are used to distinguish among arrests for drug-related, nonviolent, or violent crimes. Between the ages of 17–18 and 24, 46% of former foster youth experience an arrest. Arrests were evenly distributed across drug, nonviolent, and violent crimes columns. Although findings fail to support the significance of social bonds to interpersonal domains, bonds to employment and education are associated with a lower risk for arrest. Child welfare policy and practice implications for building connections and protections around foster youth are discussed. PMID:22239390

The evolution of civil society and the rule of law regarding female genital mutilation in Iraqi Kurdistan.

Directory of Open Access Journals (Sweden)

R. Cardone

2015-04-01

Full Text Available International human rights law relies on state sovereignty to localize suggested policy with codification and enforcement in an attempt to reconcile universalism with particularity. However, amidst domestic governance developments from post-conflict state building and self-determination, governmental instability complicates and often overlooks priorities of international human rights for more tangible domestic infrastructure, such as basic human needs rather than seemingly suggested rights ideals. This does not diminish the significance of human rights, though, pertaining to the rights of the child in addressing gender-based violence through the elimination of female genital mutilation, for example. While state-centric localization is currently prioritized for implementing international law, the rule of law is more integrated throughout the realms of societal structure, culture, and institutions in addition to the legal realm. If the legal realm is disrupted with instability, violence, and discontinuity, how does society internalize and integrate international human rights law over time, and can it be sustainable despite instability? This research evaluates the development of the rule of law, and its effectiveness, regarding female genital mutilation (FGM as a case study in Iraqi Kurdistan from the end of the Iran-Iraq War in 1988 until 2013, the early years of the Kurdistan Regional Government’s parliament. Comprehensive rule of law evolution can be measured through comparing domestic legal developments through state-centric policy and enforcement, or lack thereof, with cultural internalization and non-governmental engagements. By studying the legal and cultural realms’ interaction with the anti-FGM discourse over Iraqi Kurdistan’s past two decades, this research will determine the role of a continuous society overlaid by intermittent legal structures in the sustainability of negotiating cultural relativity with universal human rights.

The present study was conducted to investigate the impacts of active and passive immunization against synthetic inhibin and steroid-free bovine follicular fluid, respectively, on reproductive fecundity out of breeding season in Iraqi Awassi ewes. Follicular fluid was aspired from mature bovine follicles, treated with activated charcoal, and used for immunization of male rabbits for obtaining steroid free bovine follicular fluid (SFBFF) antiserum. Forty non-pregnant Awassi ewes were allocated into 4 groups (n = 10 each). At day 38 of experiment, ewes were treated with intra-vaginal MPA sponge (60 mg for 12 days). Ewes were treated at 0, 28, and 50 days with 4, 2 and 2 ml of normal saline (control; C-ve), 400, 200 and 200 µl of ovalbumine (C+ve), 400, 200 and 200 µl of inhibin (SI group), and 4 ml of normal saline at 0 day, and 4ml and 2ml of SFBFF antiserum, at 28, and 50 days (AI group). After mating with Awassi rams, pregnancy and embryo number were diagnosed using ultrasonography. Blood samples were collected at 30, 60, 90, and 120 days of pregnancy, for assessment of estradiol-17β (E2) and progesterone (P4) levels. After parturition, numbers of delivered lambs were recorded. The results revealed significant increase of P4 and significant decrease of E2 levels in SI and AI pregnant ewes than controls at 30, 60 and 90 day. Newborn number increased significantly in SI and AI treated than control ewes. Active or passive immunization against endogenous inhibin could augment reproductive fecundity out of breeding season in Iraqi Awassi ewes.

Therapeutic hypothermia is recommended for comatose adults after witnessed out-of-hospital cardiac arrest, but data about this intervention in children are limited. We conducted this trial of two targeted temperature interventions at 38 children's hospitals involving children who remained unconscious after out-of-hospital cardiac arrest. Within 6 hours after the return of circulation, comatose patients who were older than 2 days and younger than 18 years of age were randomly assigned to therapeutic hypothermia (target temperature, 33.0°C) or therapeutic normothermia (target temperature, 36.8°C). The primary efficacy outcome, survival at 12 months after cardiac arrest with a Vineland Adaptive Behavior Scales, second edition (VABS-II), score of 70 or higher (on a scale from 20 to 160, with higher scores indicating better function), was evaluated among patients with a VABS-II score of at least 70 before cardiac arrest. A total of 295 patients underwent randomization. Among the 260 patients with data that could be evaluated and who had a VABS-II score of at least 70 before cardiac arrest, there was no significant difference in the primary outcome between the hypothermia group and the normothermia group (20% vs. 12%; relative likelihood, 1.54; 95% confidence interval [CI], 0.86 to 2.76; P=0.14). Among all the patients with data that could be evaluated, the change in the VABS-II score from baseline to 12 months was not significantly different (P=0.13) and 1-year survival was similar (38% in the hypothermia group vs. 29% in the normothermia group; relative likelihood, 1.29; 95% CI, 0.93 to 1.79; P=0.13). The groups had similar incidences of infection and serious arrhythmias, as well as similar use of blood products and 28-day mortality. In comatose children who survived out-of-hospital cardiac arrest, therapeutic hypothermia, as compared with therapeutic normothermia, did not confer a significant benefit in survival with a good functional outcome at 1 year.

The use of transmission line surge arresters to improve the lightning performance of transmission lines is becoming more common. Especially in areas with high soil resistivity and ground flash density, surge arresters constitute the most effective protection mean. In this paper a methodology for assessing the surge arrester failure rate based on the electrogeometrical model is presented. Critical currents that exceed arresters rated energy stress were estimated by the use of a simulation tool. The methodology is applied on operating Hellenic transmission lines of 150 kV. Several case studies are analyzed by installing surge arresters on different intervals, in relation to the region's tower footing resistance and the ground flash density. The obtained results are compared with real records of outage rate showing the effectiveness of the surge arresters in the reduction of the recorded failure rate. The presented methodology can be proved valuable to the studies of electric power systems designers intending in a more effective lightning protection, reducing the operational costs and providing continuity of service.

The content of emergency calls for suspected cardiac arrest is rarely analyzed. This study investigated the recognition of a cardiac arrest by dispatchers and its influence on survival rates. During 8 months, voice recordings of 14,800 consecutive emergency calls were collected to audit content and cardiac arrest recognition. The presence of cardiac arrest during the call was assessed from the ambulance crew report. Included calls were placed by laypersons on site and did not involve trauma. Prevalence of cardiac arrest was 3.0%. Of the 285 cardiac arrests, 82 (29%) were not recognized during the call, and 64 of 267 suspected calls (24%) were not cardiac arrest. We analyzed a random sample (n=506) of 9230 control calls. Three-month survival was 5% when a cardiac arrest was not recognized versus 14% when it was recognized (P=0.04). If the dispatcher did not recognize the cardiac arrest, the ambulance was dispatched a mean of 0.94 minute later (P<0.001) and arrived 1.40 minutes later on scene (P=0.01) compared with recognized calls. The main reason for not recognizing the cardiac arrest was not asking if the patient was breathing (42 of 82) and not asking to describe the type of breathing (16 of 82). Normal breathing was never mentioned in true cardiac arrest calls. A logistic regression model identified spontaneous trigger words like facial color that could contribute to cardiac arrest recognition (odds ratio, 7.8 to 9.7). Not recognizing a cardiac arrest during emergency calls decreases survival. Spontaneous words that the caller uses to describe the patient may aid in faster and better recognition of a cardiac arrest.

To determine whether X90 steel pipe has enough crack arrest toughness or not, a damage model was suggested as crack arrest criterion with material parameters of plastic uniform percentage elongation and damage strain energy per volume. Fracture characteristic length which characterizes fracture zone size was suggested to be the largest mesh size on expected cracking path. Plastic uniform percentage elongation, damage strain energy per volume and fracture characteristic length of X90 were obtained by five kinds of tensile tests. Based on this criterion, a length of 24 m, Φ1219 × 16.3 mm pipe segment model with 12 MPa internal gas pressure was built and computed with fluid-structure coupling method in ABAQUS. Ideal gas state equation was used to describe lean gas behavior. Euler grid was used to mesh gas zone inside the pipe while Lagrangian shell element was used to mesh pipe. Crack propagation speed and gas decompression speed were got after computation. The result shows that, when plastic uniform percentage elongation is equal to 0.054 and damage strain energy per volume is equal to 0.64 J/mm"3, crack propagation speed is less than gas decompression speed, which means the simulated X90 gas pipe with 12 MPa internal pressure can arrest cracking itself. - Highlights: • A damage model was suggested as crack arrest criterion. • Plastic uniform elongation and damage strain energy density are material parameters. • Fracture characteristic length is suggested to be largest mesh size in cracking path. • Crack propagating simulation with coupling of pipe and gas was realized in ABAQUS. • A Chinese X90 steel pipe with 12 MPa internal pressure can arrest cracking itself.

Severe trauma is the most frequent cause of death in young people, in civilized countries with major social and vital costs. The speed of diagnostic decision making and the precocity of treatment approaches are both essential and depend on the specialists' colaboration. The present study aims to emphasize the actual situation of medical interventions in case of cardiorespiratory arrest due to trauma. 1387 patients who suffered a cardio respiratory arrest both traumatic and non-traumatic were included in order to point out the place of traumatic arrest. Resuscitation of such patients is considered useless and resource consumer by many trauma practitioners who are reporting survival rates of 0%-3.5%. As the determinant of lesions, trauma etiology was as it follows car accidents - 43%, high falls - 30%, suicidal attempts - 3%, domestic violence - 3%, other causes - 21%. Hypovolemia remains the major cause of cardiac arrest and death and that is why the efforts of emergency providers (trauma team) must be oriented towards "hidden death" in order to avoid it. This condition could be revealed and solved easier with minimal diagnostic and therapeutic maneuvers in the emergency department.

Protein synthetic requirements for caffeine amelioration of radiation-induced G/sub 2/-arrest

Rowley, R.; Colkitt, D.

Irradiated cells are arrested in G/sub 2/ (transition point [TP] = 32 min before cell selection in mitosis). Irradiated cells do not recover from G/sub 2/ arrest in the presence of cycloheximide (CHM) indicating dependence of recovery on protein synthesis. Irradiated cells in the presence of caffeine progress to mitosis without arrest. The authors investigate whether irradiated cells in the presence of caffeine require protein synthesis to progress to mitosis. Mitotic cell selection was used to monitor the progression of irradiated CHO cells (150 rad) during exposure to 5 mM caffeine and/or 50 μg/ml CHM. Protein synthesis inhibition was confirmed using /sup 3/H-leucine incorporation. Cells exposed to CHM alone are arrested in G/sub 2/ (TP=49 min), thus cells beyond this point have synthesized all proteins necessary for entry into mitosis. In the presence of caffeine, unirradiated cells exposed to CHM are not arrested at all in G/sub 2/, instead arrest occurs near the S/G/sub 2/ boundary (TP=95 min) indicating that caffeine alleviates the dependence of G/sub 2/ cell progression on protein synthesis. However, irradiated cells exposed to both caffeine and CHM are only able to progress to mitosis if beyond the CHM-TP. Irradiated cells in the presence of caffeine thus behave as untreated cells and require protein synthesis for progression to mitosis when prior to the CHM-TP

It is very suitable to select the polymer materials for the housings of surge arresters (SAs), because the polymer materials are generally soft and light weight. Therefore, many kinds of polymer-housed SAs using various polymer materials have been developed, and expanding into many countries. Considering these backgrounds, the JEC technical report (JEC-TR) 23002-2008; polymer-housed surge arrester(1) has been established based on the existent relevant standards of arresters, such as JEC-2371-2003; Insulator-housed surge arresters(2) and IEC 60099-4 Edition 2.2, Metal-oxide surge arresters (MOSAs) without gaps for a.c. systems(3) in order to introduce the technology and provide a common guide for testing of polymer-housed SAs. According as the JEC-TR, the various new applications of the polymer-housed SAs, which are caused by superior advantages such as compact, light weight, safe failure mode, anti-seismic performance, anti-pollution performance and cost efficiency design, have been realized recently in Japan. Therefore, this paper gives specific consideration on the superior performance of the polymer-housed SAs and the evaluation methods of the polymer-housed SAs, because there are some issues in the existent standards to be solved.

Conservatism of ASME KIR-reference curve with respect to crack arrest

Wallin, K.; Rintamaa, R.; Nagel, G.

1999-01-01

The conservatism of the RT NDT temperature indexing parameter and the ASME K IR -reference curve with respect to crack arrest toughness, has been evaluated. Based on an analysis of the original ASME K Ia data, it was established that inherently, the ASME K IR -reference curve corresponds to an overall 5% lower bound curve with respect to crack arrest. It was shown that the scatter of crack arrest toughness is essentially material independent and has a standard deviation of 18% and the temperature dependence of K Ia has the same form as predicted by the master curve for crack initiation toughness. The 'built in' offset between the mean 100 MPa√(m) crack arrest temperature, TK Ia , and RT NDT is 38 C (TK Ia =RT NDT +38 C) and the experimental relation between TK Ia and NDT is, TK Ia =NDT+28 C. The K IR -reference curve using NDT as reference temperature will be conservative with respect to the general 5% lower bound K Ia(5%) -curve, with a 75% confidence. The use of RT NDT , instead of NDT, will generally increase the degree of conservatism, both for non-irradiated as well as irradiated materials, close to a 95% confidence level. This trend is pronounced for materials with Charpy-V upper shelf energies below 100 J. It is shown that the K IR -curve effectively constitutes a deterministic lower bound curve for crack arrest. The findings are valid both for nuclear pressure vessel plates, forgings and welds. (orig.)

Crack arrest tests such as compact, ESSO and DCB tests were made on SA533B Cl. 1, HT80 and KD32 steels to evaluate the crack arrest toughness. The main results obtained are as follows: (1) The crack arrest toughness could be evaluated by K sub(Ia) which was obtained by the static analysis of compact test. (2) K sub(ID) determined by the dynamic analysis of compact test was greater than K sub(Ia), though K sub(ID) became close to K sub(Ia)/K sub(Q) became a unity where K sub(Q) is the stress intensity factor at the crack initiation. (3) No significant difference was observed between K sub(Ia) and K sub(ca) obtained by ESSO and DCB tests, though K sub(ca) obtained by DCB test tended to be smaller than K sub(Ia) at lower temperatures. (4) K sub(Ia) was smaller than K sub(Ic) in the transition temperature range, while it was greater than K sub(Id). In the temperature range where K sub(Ic), which was determined from J sub(Ic), decreased with temperature increase, however, it was smaller than K sub(Ia). (5) The fracture appearance transition temperature and the absorbed energy obtained by 2 mm V-notch Charpy test were appropriate parameters for representing the crack arrest toughness, while the NDT temperature was not.

Epinephrine in Out-of-hospital Cardiac Arrest: Helpful or Harmful?

Science.gov (United States)

Shao, Huan; Li, Chun-Sheng

2017-09-05

Epinephrine is the primary drug administered during cardiopulmonary resuscitation (CPR) to reverse cardiac arrest. The evidence for the use of adrenaline in out-of-hospital cardiac arrest (OHCA) and in-hospital resuscitation is inconclusive. We conducted a systematic review on the clinical efficacy of adrenaline in adult OHCA patients to evaluate whether epinephrine provides any overall benefit for patients. The EMBASE and PubMed databases were searched with the key words "epinephrine," "cardiac arrest," and variations of these terms. Data from clinical randomized trials, meta-analyses, guidelines, and recent reviews were selected for review. Sudden cardiac arrest causes 544,000 deaths in China each year, with survival occurring in CPR. There is currently insufficient evidence to support or reject epinephrine administration during resuscitation. We believe that epinephrine may have a role in resuscitation, as administration of epinephrine during CPR increases the probability of restoring cardiac activity with pulses, which is an essential intermediate step toward long-term survival. The administration of adrenaline was associated with improved short-term survival (ROSC). However, it appears that the use of adrenaline is associated with no benefit on survival to hospital discharge or survival with favorable neurological outcome after OHCA, and it may have a harmful effect. Larger placebo-controlled, double-blind, randomized control trials are required to definitively establish the effect of epinephrine.

After cardiac arrest, organ damage consequent to ischemia-reperfusion has been attributed to oxidative stress. Mild therapeutic hypothermia has been applied to reduce this damage, and it may reduce oxidative damage as well. This study aimed to compare oxidative damage and antioxidant defenses in patients treated with controlled normothermia versus mild therapeutic hypothermia during postcardiac arrest syndrome. The sample consisted of 31 patients under controlled normothermia (36°C) and 11 patients treated with 24 h mild therapeutic hypothermia (33°C), victims of in- or out-of-hospital cardiac arrest. Parameters were assessed at 6, 12, 36, and 72 h after cardiac arrest in the central venous blood samples. Hypothermic and normothermic patients had similar S100B levels, a biomarker of brain injury. Xanthine oxidase activity is similar between hypothermic and normothermic patients; however, it decreases posthypothermia treatment. Xanthine oxidase activity is positively correlated with lactate and S100B and inversely correlated with pH, calcium, and sodium levels. Hypothermia reduces malondialdehyde and protein carbonyl levels, markers of oxidative damage. Concomitantly, hypothermia increases the activity of erythrocyte antioxidant enzymes superoxide dismutase, glutathione peroxidase, and glutathione S-transferase while decreasing the activity of serum paraoxonase-1. These findings suggest that mild therapeutic hypothermia reduces oxidative damage and alters antioxidant defenses in postcardiac arrest patients. PMID:28553435

2002-05-01

We sought to determine whether pretreatment with a sodium/hydrogen-exchange inhibitor (EMD 96 785) improves myocardial performance and reduces myocardial edema after cardioplegic arrest and cardiopulmonary bypass. Anesthetized dogs (n = 13) were instrumented with vascular catheters, myocardial ultrasonic crystals, and left ventricular micromanometers to measure preload recruitable stroke work, maximum rate of pressure rise (positive and negative), and left ventricular end-diastolic volume and pressure. Cardiac output was measured by means of thermodilution. Myocardial tissue water content was determined from sequential biopsy. After baseline measurements, hypothermic (28 degrees C) cardiopulmonary bypass was initiated. Cardioplegic arrest (4 degrees C Bretschneider crystalloid cardioplegic solution) was maintained for 2 hours, followed by reperfusion-rewarming and separation from cardiopulmonary bypass. Preload recruitable stroke work and myocardial tissue water content were measured at 30, 60, and 120 minutes after bypass. EMD 96 785 (3 mg/kg) was given 15 minutes before bypass, and 2 micromol was given in the cardioplegic solution. Control animals received the same volume of saline vehicle. Arterial-coronary sinus lactate difference was similar in both animals receiving EMD 96 785 and control animals, suggesting equivalent myocardial ischemia in each group. Myocardial tissue water content increased from baseline in both animals receiving EMD 96 785 and control animals with cardiopulmonary bypass and cardioplegic arrest but was statistically lower in animals receiving EMD 96 785 compared with control animals (range, 1.0%-1.5% lower in animals receiving EMD 96 785). Preload recruitable stroke work decreased from baseline (97 +/- 2 mm Hg) at 30 (59 +/- 6 mm Hg) and 60 (72 +/- 9 mm Hg) minutes after cardiopulmonary bypass and cardioplegic arrest in control animals; preload recruitable stroke work did not decrease from baseline (98 +/- 2 mm Hg) in animals receiving

Hyperkalemia masked by pseudo-stemi infarct pattern and cardiac arrest.

Hyperkalemia is a common electrolyte abnormality and has well-recognized early electrocardiographic manifestations including PR prolongation and symmetric T wave peaking. With severe increase in serum potassium, dysrhythmias and atrioventricular and bundle branch blocks can be seen on electrocardiogram. Although cardiac arrest is a worrisome consequence of untreated hyperkalemia, rarely does hyperkalemia electrocardiographically manifest as acute ischemia. We present a case of acute renal failure complicated by malignant hyperkalemia and eventual ventricular fibrillation cardiac arrest. Recognition of this disorder was delayed secondary to an initial ECG pattern suggesting an acute ST segment elevation myocardial infarction (STEMI). Emergent coronary angiography performed showed no evidence of coronary artery disease. Pseudo-STEMI patterns are rarely seen in association with acute hyperkalemia and are most commonly described with patient without acute cardiac symptomatology. This is the first such case presenting concurrently with cardiac arrest. A brief review of this rare pseudo-infarct pattern is also given.

Cardiopulmonary resuscitation guidelines imply the use of epinephrine/adrenaline during cardiopulmonary arrest. However, in cardiac arrest situations resulting from coronary artery spasm (CAS), the use of epinephrine/adrenaline could be deleterious. A 49-year-old patient underwent an emergency coronarography with an attempt to stent the coronary arteries. Radiologic imaging revealed a positive methylergonovine maleate (Methergine, Novartis Pharmaceuticals, East Hanover, NJ) test, with subocclusive CAS in several coronary vessels leading to electromechanical dissociation. Cardiopulmonary resuscitation was performed, and intracoronary boluses of isosorbide dinitrate were given to treat CAS. Epinephrine/adrenaline was not administered during resuscitation. Spontaneous circulation was obtained after cardioversion for ventricular fibrillation, and the patient progressively regained consciousness. Resuscitation guidelines do not specify the use of trinitrate derivatives in cardiac arrest situations caused by CAS. The pros and cons of the use of nitrates and epinephrine/adrenaline during cardiac arrest caused by CAS are analyzed in this case report.

2014-01-01

AIM: To systematically review the literature on the efficacy of noninvasive methods of arresting the progression of non-cavitated occlusal carious lesions in dentin. METHODS: The Medline/PubMed, LILACS, SciELO and Scopus databases were searched to identify relevant publications through to November 2013. Only clinical trials evaluating the ability of noninvasive methods to arrest the progression of occlusal non-cavitated carious lesions in dentin were included. Screening, data extraction and quality assessment were conducted independently and in duplicate. RESULTS: Of 167 citations identified, nine full text articles were screened and five were included in the analysis. All papers reported on occlusal fissure sealing using a self-curing glass ionomer (n = 1) or resin-based (n = 4) sealant. Only the use of resin-based sealant to obliterate occlusal fissures arrested the progression of non-cavitated occlusal carious lesions in dentin. CONCLUSION: Occlusal fissure sealing with a resin-based sealant may arrest the progression of non-cavitated occlusal dentinal caries. Further clinical trials with longer follow-up times should be performed to increase scientific evidence. PMID:24868513

Mutation or common intronic variants in cardiac ion channel genes have been suggested to be associated with sudden cardiac death caused by idiopathic ventricular tachyarrhythmia. This study aimed to find mutations in cardiac ion channel genes of Korean sudden cardiac arrest patients with structurally normal heart and to verify association between common genetic variation in cardiac ion channel and sudden cardiac arrest by idiopathic ventricular tachyarrhythmia in Koreans. Study participants were Korean survivors of sudden cardiac arrest caused by idiopathic ventricular tachycardia or fibrillation. All coding exons of the SCN5A, KCNQ1, and KCNH2 genes were analyzed by Sanger sequencing. Fifteen survivors of sudden cardiac arrest were included. Three male patients had mutations in SCN5A gene and none in KCNQ1 and KCNH2 genes. Intronic variant (rs2283222) in KCNQ1 gene showed significant association with sudden cardiac arrest (OR 4.05). Four male sudden cardiac arrest survivors had intronic variant (rs11720524) in SCN5A gene. None of female survivors of sudden cardiac arrest had SCN5A gene mutations despite similar frequencies of intronic variants between males and females in 55 normal controls. Common intronic variant in KCNQ1 gene is associated with sudden cardiac arrest caused by idiopathic ventricular tachyarrhythmia in Koreans.

Synchronization and Arrest of the Budding Yeast Cell Cycle Using Chemical and Genetic Methods.

Science.gov (United States)

Rosebrock, Adam P

2017-01-03

The cell cycle of budding yeast can be arrested at specific positions by different genetic and chemical methods. These arrests enable study of cell cycle phase-specific phenotypes that would be missed during examination of asynchronous cultures. Some methods for arrest are reversible, with kinetics that enable release of cells back into a synchronous cycling state. Benefits of chemical and genetic methods include scalability across a large range of culture sizes from a few milliliters to many liters, ease of execution, the absence of specific equipment requirements, and synchronization and release of the entire culture. Of note, cell growth and division are decoupled during arrest and block-release experiments. Cells will continue transcription, translation, and accumulation of protein while arrested. If allowed to reenter the cell cycle, cells will do so as a population of mixed, larger-than-normal cells. Despite this important caveat, many aspects of budding yeast physiology are accessible using these simple chemical and genetic tools. Described here are methods for the block and release of cells in G 1 phase and at the M/G 1 transition using α-factor mating pheromone and the temperature-sensitive cdc15-2 allele, respectively, in addition to methods for arresting the cell cycle in early S phase and at G 2 /M by using hydroxyurea and nocodazole, respectively. © 2017 Cold Spring Harbor Laboratory Press.

Cardiovascular morbidity has been associated with particulate matter (PM) air pollution, although the relation between pollutants and sudden death from cardiac arrest has not been established. This study examined associations between out-of-hospital cardiac arrests and fine PM (of aerodynamic diameter ≤2.5 μm, or PM2.5), ozone, nitrogen dioxide, sulfur dioxide, and carbon monoxide in New York City. The authors analyzed 8,216 out-of-hospital cardiac arrests of primary cardiac etiology during the years 2002–2006. Time-series and case-crossover analyses were conducted, controlling for season, day-of-week, same-day, and delayed/apparent temperature. An increased risk of cardiac arrest in time-series (relative risk (RR) = 1.06, 95% confidence interval (CI): 1.02, 1.10) and case-crossover (RR = 1.04, 95% CI: 0.99, 1.08) analysis for a PM2.5 increase of 10 μg/m3 in the average of 0- and 1-day lags was found. The association was significant in the warm season (RR = 1.09, 95% CI: 1.03, 1.15) but not the cold season (RR = 1.01, 95% CI: 0.95, 1.07). Associations of cardiac arrest with other pollutants were weaker. These findings, consistent with studies implicating acute cardiovascular effects of PM, support a link between PM2.5 and out-of-hospital cardiac arrests. Since few individuals survive an arrest, air pollution control may help prevent future cardiovascular mortality. PMID:20729350

Full Text Available Care to heart arrest patient should be performed in a systematic way, based on basic protocol as well as advanced life support. The objective of this study is to assess the knowledge of the nursing staff of an intensive care unit in relation to the recognition of heart arrest and the establishment of resuscitation according to the protocols above. It is a descriptive and quantitative study which was conducted from April to June 2011. Of the 33 professionals who participated in the study, 54.5% had not undergone previous training on the theme, 93.9% partially agreed the rates of heart arrest, and only 15.2 % got all the maneuvers in ventilating intubated patient. The low hit total demonstrates the need to update the nursing staff, with periodical theoretical-practical training, and systematic assessments of the performance of the team.

Social relationships are important to health out comes. The postdeployment family reintegration literature focuses on the role of the civilian family in facilitating the transition from Active Duty military deployment to civilian society. The focus on the civilian family relationship may miss other important personal connections in veterans' lives. One such connection is the relationship many veterans have with former military unit members who served with them when deployed. Drawing on interviews with male Operation Iraqi Freedom/Operation Enduring Freedom veterans conducted from 2008 to 2009, we argue that the members of a military unit, especially during armed conflict, should be considered a resource to help the "family" reintegration process rather than impede it. This research has implications for current reintegration policy and how best to assist veterans transitioning into civilian society.

Background Survivors of out-of-hospital cardiac arrest are at high risk of recurrent arrests, many of which could be prevented with implantable cardioverter defibrillators (ICDs). We sought to determine the ICD insertion rate among survivors of out-of-hospital cardiac arrest and to determine factors associated with ICD implantation. Methods The Ontario Prehospital Advanced Life Support (OPALS) study is a prospective, multiphase, before–after study assessing the effectiveness of prehospital interventions for people experiencing cardiac arrest, trauma or respiratory arrest in 19 Ontario communities. We linked OPALS data describing survivors of cardiac arrest with data from all defibrillator implantation centres in Ontario. Results From January 1997 to April 2002, 454 patients in the OPALS study survived to hospital discharge after experiencing an out-of-hospital cardiac arrest. The mean age was 65 (standard deviation 14) years, 122 (26.9%) were women, 398 (87.7%) had a witnessed arrest, 372 (81.9%) had an initial rhythm of ventricular tachycardia or ventricular fibrillation (VT/VF), and 76 (16.7%) had asystole or another arrhythmia. The median cerebral performance category at discharge (range 1–5, 1 = normal) was 1. Only 58 (12.8%) of the 454 patients received an ICD. Patients with an initial rhythm of VT/VF were more likely than those with an initial rhythm of asystole or another rhythm to undergo device insertion (adjusted odds ratio [OR] 9.63, 95% confidence interval [CI] 1.31–71.50). Similarly, patients with a normal cerebral performance score were more likely than those with abnormal scores to undergo ICD insertion (adjusted OR 12.52, 95% CI 1.74–92.12). Interpretation A minority of patients who survived cardiac arrest underwent ICD insertion. It is unclear whether this low usage rate reflects referral bias, selection bias by electrophysiologists, supply constraint or patient preference. PMID:15505267

The effects of the medium (TCM 199 or SOFaa) and temperature (20 or 39 C) during meiotic arrest by cycloheximide (CHX) under air on the developmental competence of bovine oocytes after in vitro maturation (IVM) and fertilization (IVF) were investigated. Oocytes were maintained in meiotic arrest by 10 microg/ml CHX in a 50-microl droplet of 25-mM HEPES-buffered TCM 199 (H199) at 39 C or synthetic oviduct fluid (HSOFaa) at 20 or 39 C in air for 24 h. After release from the arrest, the oocytes was matured and fertilized in vitro and their developmental competence was examined. The developmental rate of oocytes arrested in HSOFaa at 20 C to the blastocyst stage was similar to that of non-arrested oocytes but was significantly higher (Ptransport conditions, we also investigated the meiotic arrest of oocytes maintained in a 0.25-ml straw by CHX individually with 10 microl HSOFaa or as a group (40-50 oocytes) with 170-200 microl HSOFaa at 20 C in air for 24 h. After release from meiotic arrest, the developmental competence of these oocytes was assessed similarly. The developmental rate of oocytes treated with CHX individually was similar to that of those treated with CHX in 50-microl droplet of HSOFaa at 20 C. However, the developmental rate of oocytes treated with CHX as a group was lower than that of oocytes treated with CHX in a 50-microl droplet. Five blastocysts developed from oocytes maintained in meiotic arrest in a plastic straw were transferred to five recipient heifers. Consequently, three recipients became pregnant and 2 calves were delivered. The results of the present study indicate that bovine oocytes treated with CHX in HSOFaa at 20 C under air retain the same developmental competence as non-arrested oocytes.

Based on the recently proposed self-consistent generalized Langevin equation theory of dynamic arrest, in this letter we show that the ergodic-nonergodic phase diagram of a classical mixture of charged hard spheres (the so-called 'primitive model' of ionic solutions and molten salts) includes arrested phases corresponding to nonconducting ionic glasses, partially arrested states that represent solid electrolytes (or 'superionic' conductors), low-density colloidal Wigner glasses, and low-density electrostatic gels associated with arrested spinodal decomposition.

Highlights: • TGEV N protein reduces cell viability by inducing cell cycle arrest and apoptosis. • TGEV N protein induces cell cycle arrest and apoptosis by regulating p53 signaling. • TGEV N protein plays important roles in TGEV-induced cell cycle arrest and apoptosis. - Abstract: Our previous studies showed that TGEV infection could induce cell cycle arrest and apoptosis via activation of p53 signaling in cultured host cells. However, it is unclear which viral gene causes these effects. In this study, we investigated the effects of TGEV nucleocapsid (N) protein on PK-15 cells. We found that TGEV N protein suppressed cell proliferation by causing cell cycle arrest at the S and G2/M phases and apoptosis. Characterization of various cellular proteins that are involved in regulating cell cycle progression demonstrated that the expression of N gene resulted in an accumulation of p53 and p21, which suppressed cyclin B1, cdc2 and cdk2 expression. Moreover, the expression of TGEV N gene promoted translocation of Bax to mitochondria, which in turn caused the release of cytochrome c, followed by activation of caspase-3, resulting in cell apoptosis in the transfected PK-15 cells following cell cycle arrest. Further studies showed that p53 inhibitor attenuated TGEV N protein induced cell cycle arrest at S and G2/M phases and apoptosis through reversing the expression changes of cdc2, cdk2 and cyclin B1 and the translocation changes of Bax and cytochrome c induced by TGEV N protein. Taken together, these results demonstrated that TGEV N protein might play an important role in TGEV infection-induced p53 activation and cell cycle arrest at the S and G2/M phases and apoptosis occurrence

The role of baculovirus apoptotic suppressors in AcMNPV-mediated translation arrest in Ld652Y cells

2004-01-01

Infecting the insect cell line IPLB-Ld652Y with the baculovirus Autographa californica multinucleocapsid nucleopolyhedrovirus (AcMNPV) results in global translation arrest, which correlates with the presence of the AcMNPV apoptotic suppressor, p35. In this study, we investigated the role of apoptotic suppression on AcMNPV-induced translation arrest. Infecting cells with AcMNPV bearing nonfunctional mutant p35 did not result in global translation arrest. In contrast, global translation arrest was observed in cells infected with AcMNPV in which p35 was replaced with Opiap, Cpiap, or p49, baculovirus apoptotic suppressors that block apoptosis by different mechanisms than p35. These results indicated that suppressing apoptosis triggered translation arrest in AcMNPV-infected Ld652Y cells. Experiments using the DNA synthesis inhibitor aphidicolin and temperature shift experiments, using the AcMNPV replication mutants ts8 and ts8Δp35, indicated that translation arrest initiated during the early phase of infection, but events during the late phase were required for global translation arrest. Peptide caspase inhibitors could not substitute for baculovirus apoptotic suppressors to induce translation arrest in Ld652Y cells infected with a p35-null virus. However, if the p35-null-AcMNPV also carried hrf-1, a novel baculovirus host range gene, progeny virus was produced and treatment with peptide caspase inhibitors enhanced translation of a late viral gene transcript. Together, these results indicate that translation arrest in AcMNPV-infected Ld652Y cells is due to the anti-apoptotic function of p35, but suggests that rather than simply preventing caspase activation, its activity enhances signaling to a separate translation arrest pathway, possibly by stimulating the late stages of the baculovirus infection cycle

Transfusion Associated Hyperkalemia and Cardiac Arrest in an Infant after Extracorporeal Membrane Oxygenation

Full Text Available Cardiac arrest associated with hyperkalemia during red blood cell transfusion is a rare but fatal complication. Herein, we report a case of transfusion-associated cardiac arrest following the initiation of extracorporeal membrane oxygenation support in a 9-month old infant. Her serum potassium level was increased to 9.0 mEq/L, soon after the newly primed circuit with pre-stored red blood cell (RBC was started and followed by sudden cardiac arrest. Eventually, circulation was restored and the potassium level decreased to 5.1 mEq/L after 5 min. Extracorporeal membrane oxygenation (ECMO priming is a relatively massive transfusion into a pediatric patient. Thus, to prevent cardiac arrest during blood-primed ECMO in neonates and infants, freshly irradiated and washed RBCs should be used when priming the ECMO circuit, to minimize the potassium concentration. Also, physicians should be aware of all possible complications associated with transfusions during ECMO.

Full Text Available The approach of greening existing buildings, is an urgent necessity, because the greening operation provides the speed and optimal efficiency in the environmental performance, as well as keeping up with the global green architecture revolution. Therefore, greening existing buildings in Iraq is important for trends towards renewable energies, because of what the country went through economic conditions and crises and wars which kept the country away from what took place globally in this issue. The research problem is: insufficient knowledge about the importance and the mechanism of the greening of existing buildings, including its environmental and economic dimensions, by rationalization of energy consumption and preserving the environment. The research objective is: clarifying the importance of greening existing buildings environmentally and economically, providing a virtual experience for greening the presidency building of Baghdad University, through advanced computer program. The main conclusions is: there is difference representing by reducing the disbursed thermal loads amount for cooling in summer and heating in winter through the use of computerized program (DesignBuilder and that after the implementation of greening operations on the building envelope, which confirms its effectiveness in raising the energy performance efficiency inside the building. Hence, the importance of the application of greening existing buildings approach in Iraq, to bring back Iraqi architecture to environmental and local track proper.

We examined the role of youth HIV status and other key factors on past-year arrest in perinatally HIV-exposed but uninfected (PHIV-) and perinatally HIV-infected (PHIV+) youth using data from a multi-site study of psychosocial behaviors in PHIV-exposed urban youth (N = 340; 61% PHIV+; 51% female; ages 9-16 at baseline). Youth and caregivers were administered 5 interviews, spanning approximately 7.5 years. Using longitudinal logistic mixed-effect models, we explored the association between past year arrest, internal [e.g., substance use disorder (SUD)] and external (e.g., neighborhood arrest rates) contextual factors, and social-regulation processes (e.g., in-school/work). Arrest rates increased from 2.6 to 19.7% across follow-ups; there were no differences in arrest over time by HIV status. In the final model, odds of arrest were greater for youth who were male, with SUD, ≥ 18 years old, with high levels of city stress, and neither in school nor employed. PHIV-exposed, urban youth have much higher rates of arrest than national samples. Lack of differences in arrest by HIV status suggests key contextual factors are more important in promoting arrest.

2013-04-01

Full Text Available This research deals with the viability of using polyester fiber (PF, crumb rubber tire (CRT and cellulose fiber (CF as stabilizing waste additives in producing Iraqi SMA mixtures that sustain drain down phenomenon and moisture damage sensitivity. Different ratios of these additives (0.1, 0.2, and 0.3% by weight of aggregate and filler were mixed with 40/50 paving asphalt by means of dry process. Unmodified and modified SMA mixtures were subjected to drain down, Marshall, static indirect tensile strength, tensile stiffness modulus, static compressive strength, tensile strength ratio and index of retained strength tests. A set of regression equations between these tests were established. In addition, an optimization table based on these tests, which can be used to select the type or amount of additive for any field applications has been determined and reported. The results indicated that the inclusion of these additives in SMA mixtures can satisfy the performance requirement of high temperature and much rain zone.

A Periphery Becomes a Center? Shopping Malls as Symbols of Modernity in Iraqi Kurdistan

Directory of Open Access Journals (Sweden)

2015-11-01

Full Text Available Being labelled and framed as a remote periphery of Iraq, the Kurdistan Region of Iraq is transforming since 2003 into a center attracting investments worth billions of dollars. Investigating this transformation, I scrutinize one of the visible outcomes of the investments, namely shop- ping malls, as examples and symbols of “modernity” and “progress.” The recently built shopping malls are thereby analyzed as the built materialization and symbols of neoliberal transformation and socio-economic change. Engaging with representatives of shopping malls as well as with the experiences of young female shopping-mall-goers, it will be illustrated how modernity and progress is framed within the Kurdish nationalist narrative and how this is taken up by young Kurdish female mall-goers. Thus, it will be contended that a historical narrative of past sufferings comes to legitimize the new liberal “freedoms” that are available through the full connection to and participation of Iraqi Kurdistan in the capitalist economic world system.

Resumption of spontaneous circulation (ROSC) after cardiac arrest is an unnatural pathophysiological state. In 2008, ILCOR has proposed "post-cardiac arrest syndrome (PCAS)". Clinicians must focus on treating to reverse the pathophysiological manifestations of PCAS in bed. Immobility, deconditioning, and weakness are common problems in patients with critical illness. Therapeutic strategies have to be identified to give patients after ROSC the best chance for survival with good neurological function. Concerning the beneficial effects of early mobilization after stroke, and the efficacy of a strategy for whole-body rehabilitation in the earliest days of critical illness on functional outcomes, the intervention of early rehabilitation care by an interdisciplinary team seems to contribute to good long-time outcome of post-cardiac arrest patients.

To compare the effects of moderate and deep hypothermic circulatory arrest (DHCA) with selective antegrade cerebral perfusion (SACP) during aortic arch surgery in adult patients and to offer the evidence for the detection of the temperature which provides best brain protection in the subjects who accept aortic arch reconstruction surgery. A total of 109 patients undergoing surgery of the aortic arch were divided into the moderate hypothermic circulatory arrest group (Group I) and the deep hypothermic circulatory arrest group (Group II). We recorded the data of the patients and their cardiopulmonary bypass (CPB) time, aortic clamping time, SACP time and postoperative anesthetized recovery time, tracheal intubation time, time in the intensive care unit (ICU) and postoperative neurologic dysfunction. Patient characteristics were similar in the two groups. There were four patients who died in Group II and 1 patient in Group I. There were no significant differences in aortic clamping time of each group (111.4±58.4 vs. 115.9±16.2) min; SACP time (27.4±5.9 vs. 23.5±6.1) min of the moderate hypothermic circulatory arrest group and the deep hypothermic circulatory arrest group; there were significant differences in cardiopulmonary bypass time (207.4±20.9 vs. 263.8±22.6) min, postoperative anesthetized recovery time (19.0±11.1 vs. 36.8±25.3) hours, extubation time (46.4±15.1 vs. 64.4±6.0) hours; length of stay in the intensive care unit (ICU) (4.7±1.7 vs. 8±2.3) days and postoperative neurologic dysfunction in the two groups. Compared to deep hypothermic circulatory arrest, moderate hypothermic circulatory arrest can provide better brain protection and achieve good clinical results.

An Analysis of Alternatives to New York City's Current Marijuana Arrest and Detention Policy.

Johnson, Bruce D; Golub, Andrew; Dunlap, Eloise; Sifaneck, Stephen J

During the 1990s, the New York Police Department (NYPD) instituted a policy of arresting and detaining people for minor offenses that occur in public as part of their quality-of-life (hereafter QOL) policing initiative. The number of NYPD arrests for smoking marijuana in public view (MPV) increased from 3,000 in 1994 to over 50,000 in 2000, and have been about 30,000 in the mid 2000s. Most of these arrestees (84%) have been minority; blacks have been 2.7 more likely and Hispanics 1.8 times more likely to be detained than whites for an MPV arrest. Minorities have been most likely to receive more severe dispositions, even controlling for demographics and prior arrest histories.This paper examines the pros and cons of the current policy; this is compared with possible alternatives including the following: arrest and issue a desk appearance ticket (DAT); issue a non-criminal citation (violation); street warnings; and tolerate public marijuana smoking. The authors recommend that the NYPD change to issuing DATs on a routine basis. Drug policy reformers might wish to further pursue changing statutes regarding smoking marijuana in public view into a violation (noncriminal) or encourage the wider use of street warnings. Any of these policy changes would help reduce the disproportionate burden on minorities associated with the current arrest and detention policy. These policies could help maintain civic norms against smoking marijuana in public.

Arrested hydrocephalus is stable ventriculomegaly without evidence of neurologic deterioration or symptoms. Management of arrested hydrocephalus in asymptomatic adults is controversial, with little clinical data. This case highlights the potential for decompensation in adults with arrested hydrocephalus and reviews the literature regarding pathophysiology and management of this clinical entity. A 39 year-old gentleman with arrested hydrocephalus incidentally found during work-up for new-onset seizure and managed conservatively for ten years presented with increasing headache, memory loss, gait instability and urinary and fecal incontinence. Stable massive triventriculomegaly was documented on serial brain imaging, and ophthalmologic exam revealed no papilledema. The patient underwent endoscopic third ventriculostomy with immediate post-operative improvement of headache, resolution of incontinence, and cessation of seizures. At 15 months after surgery, neuropsychiatric testing demonstrated improvement in visuomotor skills, problem solving, verbal fluency and cognitive flexibility compared to his pre-operative baseline. At 18 months after surgery he remained seizure free with full continence and significant improvement in headaches. Early recognition of arrested hydrocephalus and its potential for decompensation may prompt surgical treatment and prevent neurologic deterioration. Copyright © 2016 Elsevier B.V.

Pulver, Aaron; Wei, Ran; Mann, Clay

2016-01-01

Out-of-hospital cardiac arrest (OOHCA) is prevalent in the United States. Each year between 180,000 and 400,000 people die due to cardiac arrest. The automated external defibrillator (AED) has greatly enhanced survival rates for OOHCA. However, one of the important components of successful cardiac arrest treatment is emergency medical services (EMS) response time (i.e., the time from EMS "wheels rolling" until arrival at the OOHCA scene). Unmanned Aerial Vehicles (UAV) have regularly been used for remote sensing and aerial imagery collection, but there are new opportunities to use drones for medical emergencies. The purpose of this study is to develop a geographic approach to the placement of a network of medical drones, equipped with an automated external defibrillator, designed to minimize travel time to victims of out-of-hospital cardiac arrest. Our goal was to have one drone on scene within one minute for at least 90% of demand for AED shock therapy, while minimizing implementation costs. In our study, the current estimated travel times were evaluated in Salt Lake County using geographical information systems (GIS) and compared to the estimated travel times of a network of AED enabled medical drones. We employed a location model, the Maximum Coverage Location Problem (MCLP), to determine the best configuration of drones to increase service coverage within one minute. We found that, using traditional vehicles, only 4.3% of the demand can be reached (travel time) within one minute utilizing current EMS agency locations, while 96.4% of demand can be reached within five minutes using current EMS vehicles and facility locations. Analyses show that using existing EMS stations to launch drones resulted in 80.1% of cardiac arrest demand being reached within one minute Allowing new sites to launch drones resulted in 90.3% of demand being reached within one minute. Finally, using existing EMS and new sites resulted in 90.3% of demand being reached while greatly reducing

Full Text Available Subarachnoid hemorrhage (SAH may present with cardiac arrest (SAH-CA. We report a case of SAH-CA to assist providers in distinguishing SAH as an etiology of cardiac arrest despite electrocardiogram findings that may be suggestive of a cardiac etiology. SAH-CA is associated with high rates of return of spontaneous circulation, but overall poor outcome. An initially non-shockable cardiac rhythm and the absence of brain stem reflexes are important clues in indentifying SAH-CA.

Influence of novobiocin on mitotic events and radiation-induced G2-arrest

International Nuclear Information System (INIS)

Rowley, R.

1987-01-01

Novobiocin was used in CHO cells to test for an involvement of topoisomerase II activity in; 1) the induction of, and recovery from, radiation-induced G 2 -arrest and 2) progression through mitosis. Novobiocin blocked recovery from G 2 -arrest with a concentration dependency which suggested that this effect resulted from protein synthesis inhibition. Novobiocin alone, at concentrations above 500 μgml, blocked cell progression in early mitosis. The transition point was distinct from that of protein and RNA synthesis inhibitors and was the only arrest point in mitosis. A similar block was imposed by coumermycin. While this may indicate a requirement for topoisomerase II activity during chromosome condensation, it was also associated with inhibition of histone phosphorylation. Histone H3 phosphorylation is believed to be necessary for chromosome condensation and, when inhibited by novobiocin, correlates with a block in premature chromatin condensation in tsBN2 cells. The authors' data thus unite these two findings, provide an opportunity to analyse the temporal relationship between histone phosphorylation and mitotic events and suggest that topological reorganization of the chromatin is not involved in radiation-induced G 2 arrest

There may be a pathological connection between cardiac failure and ischemic stroke.In this article we describe pertinent research that demonstrates subsequent death of cardiac and neural myocytes in the post ischemic stroke brain.Current stroke therapy overlooks the connection between cardiac and cerebrovascular events and fails to address the shared risk factors.Current pre-clinical stroke investigations have provided evidence that suggests the presence of an indirect cell death pathway in which toxic molecules emanate from the stroke brain and trigger cardiac cell death.On the other hand,other studies highlight the presence of a reverse cell death cascade in which toxic molecules from the heart,following cardiac arrest,travel to the brain and induce ischemic cell death.Further examination of these putative cell death pathways between ischemic stroke and cardiac arrest will prompt the advancement of innovative treatments specifically targeting both diseases,leading to ameliorated clinical results of patients diagnosed with heart failure and ischemic stroke.

Growth-arrest-specific protein 2 inhibits cell division in Xenopus embryos.

Directory of Open Access Journals (Sweden)

Tong Zhang

Full Text Available Growth-arrest-specific 2 gene was originally identified in murine fibroblasts under growth arrest conditions. Furthermore, serum stimulation of quiescent, non-dividing cells leads to the down-regulation of gas2 and results in re-entry into the cell cycle. Cytoskeleton rearrangements are critical for cell cycle progression and cell division and the Gas2 protein has been shown to co-localize with actin and microtubules in interphase mammalian cells. Despite these findings, direct evidence supporting a role for Gas2 in the mechanism of cell division has not been reported.To determine whether the Gas2 protein plays a role in cell division, we over-expressed the full-length Gas2 protein and Gas2 truncations containing either the actin-binding CH domain or the tubulin-binding Gas2 domain in Xenopus laevis embryos. We found that both the full-length Gas2 protein and the Gas2 domain, but not the CH domain, inhibited cell division and resulted in multinucleated cells. The observation that Gas2 domain alone can arrest cell division suggests that Gas2 function is mediated by microtubule binding. Gas2 co-localized with microtubules at the cell cortex of Gas2-injected Xenopus embryos using cryo-confocal microscopy and co-sedimented with microtubules in cytoskeleton co-sedimentation assays. To investigate the mechanism of Gas2-induced cell division arrest, we showed, using a wound-induced contractile array assay, that Gas2 stabilized microtubules. Finally, electron microscopy studies demonstrated that Gas2 bundled microtubules into higher-order structures.Our experiments show that Gas2 inhibits cell division in Xenopus embryos. We propose that Gas2 function is mediated by binding and bundling microtubules, leading to cell division arrest.

Erroneously arising tetraploid mammalian cells are chromosomally instable and may facilitate cell transformation. An increasing body of evidence shows that the propagation of mammalian tetraploid cells is limited by a p53-dependent arrest. The trigger of this arrest has not been identified so far. Here we show by live cell imaging of tetraploid cells generated by an induced cytokinesis failure that most tetraploids arrest and die in a p53-dependent manner after the first tetraploid mitosis. Furthermore, we found that the main trigger is a mitotic defect, in particular, chromosome missegregation during bipolar mitosis or spindle multipolarity. Both a transient multipolar spindle followed by efficient clustering in anaphase as well as a multipolar spindle followed by multipolar mitosis inhibited subsequent proliferation to a similar degree. We found that the tetraploid cells did not accumulate double-strand breaks that could cause the cell cycle arrest after tetraploid mitosis. In contrast, tetraploid cells showed increased levels of oxidative DNA damage coinciding with the p53 activation. To further elucidate the pathways involved in the proliferation control of tetraploid cells, we knocked down specific kinases that had been previously linked to the cell cycle arrest and p53 phosphorylation. Our results suggest that the checkpoint kinase ATM phosphorylates p53 in tetraploid cells after abnormal mitosis and thus contributes to proliferation control of human aberrantly arising tetraploids.

The technique of nuclear fission track analysis with solid state nuclear track detectors CR-39 has been applied to determine concentrations of uranium in cancerous samples of human tissues that excised from patients in the three key southern Iraqi governorates namely, Basrah, Dhi-Qar, and Muthanna. These provinces were the sites of intensive military events during the Gulf Wars in 1991 and 2003. The investigation was based on the study of 24 abnormal samples and 12 normal samples for comparing the results. These samples include four types of soft tissues (kidney, breast, stomach and uterus). The results show that uranium concentrations in the normal tissues ranged between (1.42-4.76 μg kg -1 ), whereas in the cancerous tissues ranged between (3.37-7.22 μg kg -1 ). The uranium concentrations in the normal tissues were significantly lower than in the abnormal tissues (P < 0.001). (author)

Results of crack-arrest tests on irradiated a 508 class 3 steel

Ten crack-arrest toughness values for irradiated specimens of A 508 class 3 forging steel have been obtained. The tests were performed according to the American Society for Testing and Materials (ASTM) Standard Test Method for Determining Plane-Strain Crack-Arrest Fracture Toughness, K la of Ferritic Steels, E 1221-88. None of these values are strictly valid in all five ASTM E 1221-88 validity criteria. However, they are useful when compared to unirradiated crack-arrest specimen toughness values since they show the small (averaging approximately 10 degrees C) shifts in the mean and lower-bound crack-arrest toughness curves. This confirms that a low copper content in ASTM A 508 class 3 forging material can be expected to result in small shifts of the transition toughness curve. The shifts due to neutron irradiation of the lower bound and mean toughness curves are approximately the same as the Charpy V-notch (CVN) 41-J temperature shift. The nine crack-arrest specimens were irradiated at temperatures varying from 243 to 280 degrees C, and to a fluence varying from 1.7 to 2.7 x 10 19 neutrons/cm 2 (> 1 MeV). The test results were normalized to reference values that correspond to those of CVN specimens irradiated at 284 degrees C to a fluence of 3.2 x 10 19 neutrons/cm 2 (> 1 MeV) in the same capsule as the crack-arrest specimens. This adjustment resulted in a shift to lower temperatures of all the data, and in particular moved two data points that appeared to lie close to or lower than the American Society of Mechanical Engineers K la curve to positions that seemed more reasonable with respect to the remaining data. A special fixture was designed, fabricated, and successfully used in the testing. For reasons explained in the text, special blocks to receive the Oak Ridge National Laboratory clip gage were designed, and greater-than-standard crack-mouth opening displacements measured were accounted for. 24 refs., 13 figs., 12 tabs

Guidelines for cardiopulmonary resuscitation recommend a chest compression rate of at least 100 compressions per minute. Animal and human studies have reported that blood flow is greatest with chest compression rates near 120/min, but few have reported rates used during out-of-hospital (OOH) cardiopulmonary resuscitation or the relationship between rate and outcome. The purpose of this study was to describe chest compression rates used by emergency medical services providers to resuscitate patients with OOH cardiac arrest and to determine the relationship between chest compression rate and outcome. Included were patients aged ≥ 20 years with OOH cardiac arrest treated by emergency medical services providers participating in the Resuscitation Outcomes Consortium. Data were abstracted from monitor-defibrillator recordings during cardiopulmonary resuscitation. Multiple logistic regression analysis assessed the association between chest compression rate and outcome. From December 2005 to May 2007, 3098 patients with OOH cardiac arrest were included in this study. Mean age was 67 ± 16 years, and 8.6% survived to hospital discharge. Mean compression rate was 112 ± 19/min. A curvilinear association between chest compression rate and return of spontaneous circulation was found in cubic spline models after multivariable adjustment (P=0.012). Return of spontaneous circulation rates peaked at a compression rate of ≈ 125/min and then declined. Chest compression rate was not significantly associated with survival to hospital discharge in multivariable categorical or cubic spline models. Chest compression rate was associated with return of spontaneous circulation but not with survival to hospital discharge in OOH cardiac arrest.

Full Text Available Introduction. Elevated intracranial pressure that occurs at the time of cerebral aneurysm rupture can lead to inadequate cerebral blood flow, which may mimic the brain injury cascade that occurs after cardiac arrest. Insights from clinical trials in cardiac arrest may provide direction for future early brain injury research after subarachnoid hemorrhage (SAH. Methods. A search of PubMed from 1980 to 2012 and clinicaltrials.gov was conducted to identify published and ongoing randomized clinical trials in aneurysmal SAH and cardiac arrest patients. Only English, adult, human studies with primary or secondary mortality or neurological outcomes were included. Results. A total of 142 trials (82 SAH, 60 cardiac arrest met the review criteria (103 published, 39 ongoing. The majority of both published and ongoing SAH trials focus on delayed secondary insults after SAH (70%, while 100% of cardiac arrest trials tested interventions within the first few hours of ictus. No SAH trials addressing treatment of early brain injury were identified. Twenty-nine percent of SAH and 13% of cardiac arrest trials showed outcome benefit, though there is no overlap mechanistically. Conclusions. Clinical trials in SAH assessing acute brain injury are warranted and successful interventions identified by the cardiac arrest literature may be reasonable targets of the study.

To determine out-of-hospital cardiac arrest survival rates before and after implementation of the Take Heart America program (a community-based initiative that sequentially deployed all of the most highly recommended 2005 American Heart Association resuscitation guidelines in an effort to increase out-of-hospital cardiac arrest survival). Out-of-hospital cardiac arrest patients in Anoka County, MN, and greater St. Cloud, MN, from November 2005 to June 2009. Two sites in Minnesota with a combined population of 439,692 people (greater St. Cloud and Anoka County) implemented: 1) widespread cardiopulmonary resuscitation and automated external defibrillator skills training in schools and businesses; 2) retraining of all emergency medical services personnel in methods to enhance circulation, including minimizing cardiopulmonary resuscitation interruptions, performing cardiopulmonary resuscitation before and after single-shock defibrillation, and use of an impedance threshold device; 3) additional deployment of automated external defibrillators in schools and public places; and 4) protocols for transport to and treatment by cardiac arrest centers for therapeutic hypothermia, coronary artery evaluation and treatment, and electrophysiological evaluation. More than 28,000 people were trained in cardiopulmonary resuscitation and automated external defibrillator use in the two sites. Bystander cardiopulmonary resuscitation rates increased from 20% to 29% (p = .086, odds ratio 1.7, 95% confidence interval 0.96-2.89). Three cardiac arrest centers were established, and hypothermia therapy for admitted out-of-hospital cardiac arrest victims increased from 0% to 45%. Survival to hospital discharge for all patients after out-of-hospital cardiac arrest in these two sites improved from 8.5% (nine of 106, historical control) to 19% (48 of 247, intervention phase) (p = .011, odds ratio 2.60, confidence interval 1.19-6.26). A financial analysis revealed that the cardiac arrest centers

The Heavy-Section Steel Technology (HSST) Program at the Oak Ridge National Laboratory (ORNL) under the sponsorship of the US Nuclear Regulatory Commission is continuing to improve the understanding of conditions that govern the initiation, rapid propagation, arrest, and ductile tearing of cracks in reactor pressure vessel (RPV) steels. This paper describes recent advances in a coordinated effort being conducted under the HSST Program by ORNL and several subcontracting groups to develop the crack-arrest data base and the analytical tools required to construct inelastic dynamic fracture models for RPV steels. Large-scale tests are being carried out to generate crack-arrest toughness data at temperatures approaching and above the onset of Charpy upper-shelf behavior. Small- and intermediate-size specimens subjected to static and dynamic loading are being developed and tested to provide additional fracture data for RPV steels. Viscoplastic effects are being included in dynamic fracture models and computer programs and their utility validated through analyses of data from carefully controlled experiments. Recent studies are described that examine convergence problems associated with energy-based fracture parameters in viscoplastic-dynamic fracture applications. Alternative techniques that have potential for achieving convergent solutions for fracture parameters in the context of viscoplastic-dynamic models are discussed. 46 refs., 15 figs., 3 tabs

The experiences of male sudden cardiac arrest survivors and their partners: a gender analysis.

To explore how masculinities shape the experiences of men and their partners after survival from out-of-hospital cardiac arrest. Survivors of out-of-hospital cardiac arrest report depression, dependence on others for daily functioning, decreased participation in society and significant decreases in quality of life. There is growing evidence that masculine gender identities play a central role in the recovery experiences of men and their families following other major cardiac events. However, to date, there has been no examination of how masculinities shape men's experiences of recovery following out-of-hospital cardiac arrest. Interview study guided by an interpretive description approach. Data were subjected to thematic analysis. A purposive sample of seven male sudden cardiac arrest survivors and 6 female partners was recruited in 2010 from a secondary care centre in British Columbia, Canada. Three themes were prominent in the experiences of the participants: (1) Support and self-reliance; (2) Dealing with emotional (in) vulnerability; and (3) No longer a 'He-man'. Masculinities played a role in men's experiences of recovery and adaptation following out-of-hospital cardiac arrest. Hegemonic masculinity partly explained men's experiences, notably their reluctance to seek professional support and reactions to changes in lifestyle. However, the study also suggests that the popular stereotype of men being 'strong and silent' in the face of ill-health may only be a part of a more complex story. Nurses would benefit from taking into consideration the potential influence of male gender identities on men's recovery postcardiac arrest. © 2014 John Wiley & Sons Ltd.

Deficits in cognitive function are a well-known dysfunction in survivors of cardiac arrest. However, data concerning memory function in this neurological vulnerable patient collective remain scarce and inconclusive. Therefore, we aimed to assess multiple aspects of retrospective and prospective memory performance in patients after cardiac arrest. We prospectively enrolled 33 survivors of cardiac arrest, with cerebral performance categories (CPC) 1 and 2 and a control-group (n=33) matched in sex, age and educational-level. To assess retrospective and prospective memory performance we administrated 4 weeks after cardiac arrest the "Rey Adult Learning Test" (RAVLT), the "Digit-Span-Backwards Test", the "Logic-Memory Test" and the "Red-Pencil Test". Results indicate an impairment in immediate and delayed free recall, but not in recognition. However, the overall impairment in immediate recall was qualified by analyzing RAVLT performance, showing that patients were only impaired in trials 4 and 5 of the learning sequence. Moreover, working and prospective memory as well as prose recall were worse in cardiac arrest survivors. Cranial computed tomography was available in 61% of all patients (n=20) but there was no specific neurological damage detectable that could be linked to this cognitive impairment. Episodic long-term memory functioning appears to be particularly impaired after cardiac arrest. In contrast, short-term memory storage, even tested via free-call, seems not to be affected. Based on cranial computed tomography we suggest that global brain ischemia rather than focal brain lesions appear to underlie these effects. Copyright © 2014 Elsevier Ireland Ltd.

In a prior study of seven North American cities Pittsburgh had the highest crude rate of cardiac arrest deaths in patients 18 to 64 years of age, particularly in neighborhoods with lower socioeconomic status (SES). We hypothesized that lower SES, associated poor health behaviors (e.g., illicit drug use) and pre-existing comorbid conditions (grouped as socioeconomic factors [SE factors]) could affect the type and severity of cardiac arrest, thus outcomes. We retrospectively identified patients aged 18 to 64 years treated for in-hospital (IHCA) and out-of hospital arrest (OHCA) at two Pittsburgh hospitals between January 2010 and July 2012. We abstracted data on baseline demographics and arrest characteristics like place of residence, insurance and employment status. Favorable cerebral performance category [CPC] (1 or 2) was our primary outcome. We examined the associations between SE factors, cardiac arrest variables and outcome as well as post-resuscitation care. Among 415 subjects who met inclusion criteria, unfavorable CPC were more common in patients who were unemployed, had a history of drug abuse or hypertension. In OHCA, favorable CPC was more often associated with presentation with ventricular fibrillation/tachycardia (OR 3.53, 95% CI 1.43-8.74, p = 0.006) and less often associated with non-cardiovascular arrest etiology (OR 0.22, 95% CI 0.08-0.62, p = 0.004). We found strong associations between specific SE factors and arrest factors associated with outcome in OHCA patients only. Significant differences in post-resuscitation care existed based on injury severity, not on SES. SE factors strongly influence type and severity of OHCA but not IHCA resulting in an association with outcomes. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

Estimating cost-effectiveness of mass cardiopulmonary resuscitation training strategies to improve survival from cardiac arrest in private locations.

Most cardiopulmonary resuscitation (CPR) trainees are young, and most cardiac arrests occur in private residences witnessed by older individuals. To estimate the cost-effectiveness of a CPR training program targeted at citizens over the age of 50 years compared with that of current nontargeted public CPR training. A model was developed using cardiac arrest and known demographic data from a single suburban zip code (population 36,325) including: local data (1997-1999) regarding cardiac arrest locations (public vs. private); incremental survival with CPR (historical survival rate 7.8%, adjusted odds ratio for CPR 2.0); arrest bystander demographics obtained from bystander telephone interviews; zip code demographics regarding population age and distribution; and 12.50 dollars per student for the cost of CPR training. Published rates of CPR training programs by age were used to estimate the numbers typically trained. Several assumptions were made: 1) there would be one bystander per. arrest; 2) the bystander would always perform CPR if trained; 3) cardiac arrest would be evenly distributed in the population; and 4) CPR training for a proportion of the population would proportionally increase CPR provision. Rates of arrest, bystanders by age, number of CPR trainees needed to result in increased arrest survival, and training cost per life saved for a one-year study period were calculated. There were 24.3 cardiac arrests per year, with 21.9 (90%) occurring in homes. In 66.5% of the home arrests, the bystander was more than 50 years old. To yield one additional survivor using the current CPR training strategy, 12,306 people needed to be trained (3,510 bystanders aged 50 years), which resulted in CPR provision to 7.14 additional patients. The training cost per life saved for a bystander aged 50 years was 785,040 dollars. Using a strategy of training only those cost of 53,383 dollars per life saved. Using these assumptions, current CPR training strategy is not a cost

We describe two cases of cardiac arrest due to hyperkalemia following transfusion of irradiated packed red cells. Case 1: Because sudden, rapid and massive hemorrage occurred in a 69-year-old male patient undergoing the left lobectomy of the liver, 8 units of irradiated packed red cells were rapidly transfused, the patient developed cardiac arrest. Serum kalium concentration after transfusion was 7.6 mEq/l. Case 2: A 7-month-old girl scheduled for closure of a ventricular septal defect, developed cardiac arrest due to hyperkalemia at the start of cardiopulmonary bypass. The extracorporeal circuit was primed with 6 units of irradiated packed red blood cells. Serum kalium concentration immediately after the start of cardiopulmonary bypass was 10.6 mEq/l. Analysis of kalium concentration in the pilot tubes of the same packs revealed 56-61 mEq/l. These case reports suggest that fresh irradiated packed red cells should be transfused during massive bleeding and for pediatric patients to prevent severe hyperkalemia. (author)

The objective of this study was to determine the effect of neutron irradiation on the shift and shape of the lower-bound curve to crack-arrest data. Two submerged-arc welds with copper contents of 0.23 and 0.31 wt % were commercially fabricated in 220-mm-thick plate. Crack-arrest specimens fabricated from these welds were irradiated at a nominal temperature of 288 degree C to an average fluence of 1.9 x 10 19 neutrons/cm 2 (>1 MeV). Evaluation of the results shows that the neutron-irradiation-induced crack-arrest toughness temperature shift is about the same as the Charpy V-notch impact temperature shift at the 41-J energy level. The shape of the lower-bound curves (for the range of test temperatures covered) did not seem to have been altered by irradiation compared to those of the ASME K Ia curve. 9 refs., 21 figs., 10 tabs

To examine levels of psychological distress and help seeking behaviour in resettled refugees attending English tuition classes in Australia, and their associations with participants' demographic characteristics. Data was collected by bilingual interviewers between March and November 2013. A volunteer sample of attendees of Adult Migrant English Programs (AMEP) in Western Sydney were recruited. Participants were two hundred and twenty five Iraqi refugees resettled in Western Sydney, who had left Iraq no earlier than 1991, were fluent in Arabic and/or English, and were between the ages of 18 and 70. The chief outcome measures used were the Kessler Psychological Distress Scale (K-10) as well as The Harvard Trauma Questionnaire (HTQ). On the K-10, 39.8% of participants had severe psychological distress, 19.4% moderate distress, and 40.7% had low to mild distress. Ninety-five percent of participants reported having experienced one or more potentially traumatic event (PTE) as defined by the HTQ prior to leaving Iraq, with a mean of 14.28 events (SD = 8.69). Thirty-one percent of participants met the threshold (≥2.5) for clinically significant PTSD symptomatology, with a significantly higher occurrence among participants with lower education attainment (χ (2) (3) = 8.26, p = .04). Of those participants with clinically significant PTSD symptomatology according to the HTQ, only 32.9% reported ever having ever sought help for a mental health problem. The high level of distress found in this sample, combined with low uptake of mental health care, highlights the need for programs targeted to promote help-seeking among Iraqi refugees who have resettled in Australia. Further, the higher level of PTSD symptomatology found amongst those with lower education attainment has mental health promotion and treatment implications. Specifically, in designing service and treatment programs, consideration should be given to the possible impact excessive levels of psychological

Full Text Available This Experiment was conducted in the Newashi village of Thiqar province in the south of Iraq from 15 October till 31 December 2006. A sample of 50 milking buffaloes in 1st to 7th lactation were randomly choosed in three nearby herds , then divided into two equal groups for the treatment and the control. After 10 days of adaptation, the treated group was fed the standardized diet which was consisted of: Alfa Alfa hay ,12 kg/day, concentrates, 8 kg/day. The concentrate consists of barley grains 37%, maize grain 15%, wheat bran 40%, rice bran 5%,calcium carbonate 2% and food salt 1% .The control group was fed -as it is usual in the region –reed roughages , rice straws, dray bred and some wheat bran. Daily milk yield for the whole sample, cream( ghiamer and fat percent rom randomly choosed individuals from each group were measured . Simple linear model was used to detect the effect of the lactation, herd, calf sex and milking time on the traits . Duncan test was used to compare the differences between means . The results obtained showed that the lactation , herd, sex of calf and milking time had significant effect on the traits (p< 0.001. The diet had significantly affected daily milk yield , cream and fat percent ( 8.40 ± 1.75 vis 5.67 ± 1.41,21± 6.6 vis 9.79 3.24, and 12.4.11 vis 5.88±1.95 for the treated group vis. the control group (p<0.001.Accordingly, it can be assumed that the Iraqi buffaloes have good potential to produce more milk and fat under standardized feed condition.

Previous studies on cardiac arrest in mountainous areas were focused on environmental features such as altitude and temperature. However, those are limited to factors affecting the prognosis of patients after cardiac arrest. We analyzed the cardiac arrests in national or provincial parks located in the mountains and determined the factors affecting the prognosis of patients after cardiac arrest. This study included all emergency medical service (EMS) treated patients over the age of 40 experiencing out-of-hospital cardiac arrests (OHCAs) of presumed cardiac etiology during exercise, between January 2012 and December 2015. The main focus of interest was the location of cardiac arrest occurrence (national mountain parks and provincial parks vs. other sites). The main outcome was survival to discharge and multivariable logistic regression was performed to adjust for possible confounding effects. A total 1835 patients who suffered a cardiac arrest while exercising were included. From these, 68 patients experienced cardiac arrest in national or provincial parks, and 1767 occurred in other locations. The unadjusted and adjusted ORs (95% CI) for a good cerebral performance scale (CPC) were 0.09 (0.01-0.63) and 0.08(0.01-0.56), survival discharges were 0.13(0.03-0.53) and 0.11 (0.03-0.48). Cardiac arrests occurring while exercising in the mountainous areas have worse prognosis compared to alternative locations. Copyright © 2017. Published by Elsevier Inc.

By 2000, MPV accounted for 15% of all arrests. The NYPD's supporters report this arrest activity is just part of quality-of-life (QOL policing, which seeks to promote order in public locations by aggressively patrolling for behaviors that offend the general population. The NYPD's critics contend the NYPD has disproportionately targeted poor, black and Hispanic communities. Methods This paper analyzes the geographic distribution of MPV arrests from 1992 to 2003 to evaluate these alternative perspectives. A sequence of maps identify that the focus of MPV arrests shifted over time. Results In the early 1990s, most MPV arrests were recorded in the lower half of Manhattan (NYC's business and cultural center and by the transit police. However, in the later 1990s and into the 2000s, most MPV arrests were recorded in high poverty, minority communities outside the lower Manhattan area and by the NYPD's policing of low-income housing projects. Conclusion These findings suggest that current levels of MPV arrests in NYC may not be justifiable, at least based solely on the purpose of QOL policing. Accordingly, we suggest the NYPD seriously consider less stringent measures for public marijuana smokers, especially for use outside of highly public locations in recessed locations hidden from open view (like the stairwell of a housing project. Alternatives could include Desk Appearance Tickets, fines, or simply requiring smokers to desist, discard their product, and move along.

Paediatric cardiopulmonary arrest (CPA) survival rates are strongly linked to the training of the doctors responding to the event. This study sought to characterise the level of experience in managing CPAs among paediatric trainees and to investigate the nontechnical (NTS) required to effectively lead a paediatric CPA team. A mixed-methods research design was used. For the quantitative phase, a questionnaire was developed to assess training, confidence, and experiences related to CPA management. During the qualitative phase, 17 paediatric trainees participated in a series of critical incident technique (CIT) interviews to explore the NTS used during the management of paediatric CPAs. A total of 56 of 131 (37.1% response rate) trainees responded to the preparedness questionnaire. A total of 48.2% of respondents expressed low confidence in their skill as a team leader during the management of a CPA. The CIT interviews highlighted deficiencies in specific NTS (identifying options, prioritising, and identifying and utilising resources). Our results indicate that there is a desire for more training in CPA management among paediatric trainees, in particular as a team leader, which includes a focus on key NTS. What is Known • Levels of preparedness to be a paediatric cardiopulmonary arrests team member/leader are generally lower than desirable. • The importance of nontechnical skills to the effective performance of adult cardiopulmonary arrests teams has been identified. What is New • Levels of preparedness to be a cardiopulmonary arrests team member were higher than reported in US studies. • There is a need for greater training in cardiopulmonary arrest management which includes a focus on key nontechnical skills to include identifying options, prioritising, identifying and utilising resources.

Objective: To observe the cell cycle arrest changes in peripheral blood mononuclear cells (PBMNCs) of normal persons and several kinds of tumor cell lines after 60 Co γ-irradiation. Methods: PBMNCs of normal persons, HL-60, K562, SiHA and 113 tumor cell lines were irradiated with 60 Co γ-rays at the absorbed doses of 6, 10,15 Gy. Cell cycles changes were checked 6, 12, 24, 48 and 60 h after the irradiation. Results: A stasis state was observed in normal person PBMNCs, 95 percents of which were in G 1 phase, and they still remained stasis after the irradiation. Except the 113 cell line manifesting G 1 phase arrest, all other tumor cell lines showed G 2 /M phase arrest after irradiation. The radiation sensitivity of HL-60 was higher than that of SiHA cell line. Conclusion: Different cell lines have different cell cycle arrest reaction to radiation and their radiation sensitivity are also different

Severe and partly irreversible G2 arrest caused by americium-241 alpha-particles in Chinese hamster V79 cells acted as a competing process to the yield of detectable aberrant mitoses at metaphase. With increasing dose of alpha-radiation an increasing fraction of cells was irreversibly arrested in G2 with the consequence of interphase death before the first post-irradiation mitosis. This irreversible G2 arrest (demonstrated by flow cytofluorometry and mitotic indices) could be overcome by adding caffeine 8 hours after irradiation, the time point of maximum G2 arrest (80-90 per cent of all cells). Within 3.5 hours the number of aberrant mitoses increased by this treatment from 54 to 96 per cent and from 65 to 99.9 per cent for doses of 1.75 and 4.38 Gy of alpha-particles, respectively. The aberration frequency per mitotic cell, scored as chromatid and isochromatid breaks, rings, interchanges and dicentrics increased by a factor of about 3 after releasing G2 arrested cells. The frequency distribution of aberrations per cell revealed that, after 4.38 Gy, 58 per cent of the formerly G2-arrested cells had more than five aberrations per cell compared to only 8 per cent without the interaction of caffeine.

Full Text Available ‘Eghterab’ in Iraqi Emigrants' Poetry: The Case of Ahmad Matar    Jafar Delshad *  Seyyed Adnan Eshkewaree **    Abstract  The word ‘eghterab’ in human sciences has different concepts which could be classified into three groups: 1 Westernization and tending to western culture or being alien with eastern authenticity 2 nostalgia and homesickness caused by being away from his/her motherhood land and hometown. Most of this group of poets are emigrants or are in exile and 3 having the sense of nostalgia but being in home country. It means that this group of poets have very high ideals which no one in their homeland can take and bare these ideals. The poet perceives that ideals which are essential for him/her are higher than the society in which he/she lives can grasp. This essay makes an attempt to study the various concepts of ‘eghterab’ by focusing on Ahmad Matar as a prominent poet with regard to the third concept and deal with the third concept of Eghterab from three points of view: political, social and spiritual. This article examines some samples of these three parts in Ahmad Matar's poetry.    Key words: nostalgia, poetry, emigration, Ahmad Matar, Iraq   * Assistant Professor, Department of Arabic Language and Literature, University of IsfahanE-mail: delshad@fgn.ui.ir  ** Assistant Professor, University for Teacher Training, E-mail: eshkewaree@yahoo.com.

This ex vivo study compared the physico-chemical structural differences between primary carious teeth biannually treated with silver diamine fluoride (SDF) and carious teeth without such treatment. Twelve carious primary upper-central incisors were collected from 6-year-old children. Six teeth had arrested caries after 24-month biannual SDF applications and 6 had active caries when there was no topical fluoride treatment. The mineral density, elemental contents, surface morphology, and crystal characteristics were assessed by micro-computed tomography (micro-CT), energy-dispersive X-ray spectrometry (EDX), scanning electron microscopy (SEM), and transmission electron microscopy (TEM). Micro-CT examination revealed a superficial opaque band approximately 150μm on the arrested cavitated dentinal lesion. This band was limited in the active carious lesion. EDX examination detected a higher intensity of calcium and phosphate of 150μm in the surface zone than in the inner zone, but this zone was restricted in the active cavitated dentinal lesion. SEM examination indicated that the collagens were protected from being exposed in the arrested cavitated dentinal lesion, but were exposed in the active cavitated dentinal lesion. TEM examination suggested that remineralised hydroxyapatites were well aligned in the arrested cavitated dentinal lesion, while those in the active cavitated dentinal lesion indicated a random apatite arrangement. A highly remineralised zone rich in calcium and phosphate was found on the arrested cavitated dentinal lesion of primary teeth with an SDF application. The collagens were protected from being exposed in the arrested cavitated dentinal lesion. Clinical SDF application positively influences dentine remineralisation. Copyright © 2013 The Authors.

Rotariu, Elena L; Manole, Mioara D

2017-08-01

Lightning strike injuries, although less common than electrical injuries, have a higher morbidity rate because of critical alterations of the circulatory system, respiratory system, and central nervous system. Most lightning-related deaths occur immediately after injury because of arrhythmia or respiratory failure. We describe the case of a pediatric patient who experienced cardiorespiratory arrest secondary to a lightning strike, where the Advanced Cardiac Life Support and Basic Life Support chain of survival was well executed, leading to return of spontaneous circulation and intact neurological survival. We review the pathophysiology of lightning injuries, prognostic factors of favorable outcome after cardiac arrest, including bystander cardiopulmonary resuscitation, shockable rhythm, and automatic external defibrillator use, and the importance of temperature management after cardiac arrest.

The ubiquitous spread of polybrominated diphenyl ethers (PBDEs) has led to concerns regarding the metabolites of these congeners, in particular hydroxylated PBDEs. There are limited studies regarding the biological interactions of these chemicals, yet there is some concern they may be more toxic than their parent compounds. In this study three hydroxylated PBDEs were assessed for toxicity in embryonic zebrafish: 3-OH-BDE 47, 5-OH-BDE 47, and 6-OH-BDE 47. All three congeners induced developmental arrest in a concentration-dependent manner; however, 6-OH-BDE 47 induced adverse effects at lower concentrations than the other congeners. Furthermore, all three induced cell death; however apoptosis was not observed. In short-term exposures (24–28 hours post fertilization), all hydroxylated PBDEs generated oxidative stress in the region corresponding to the cell death at 5 and 10 ppm. To further investigate the short-term effects that may be responsible for the developmental arrest observed in this study, gene regulation was assessed for embryos exposed to 0.625 ppm 6-OH-BDE 47 from 24 to 28 hpf. Genes involved in stress response, thyroid hormone regulation, and neurodevelopment were significantly upregulated compared to controls; however, genes related to oxidative stress were either unaffected or downregulated. This study suggests that hydroxylated PBDEs disrupt development, and may induce oxidative stress and potentially disrupt the cholinergic system and thyroid hormone homeostasis. -- Highlights: ► OH-PBDEs induce developmental arrest in a concentration-dependent manner. ► Hydroxyl group location influences biological interaction. ► OH-PBDEs induce oxidative stress. ► Thyroid hormone gene regulation was disrupted following exposure. ► To our knowledge, this is the first whole organism study of OH-PBDE toxicity.

Trauma exposure contributes to poor mental health among refugees, and exposure often is measured using a cumulative index of items from the Harvard Trauma Questionnaire (HTQ). Few studies, however, have asked whether trauma subtypes derived from the HTQ could be superior to this cumulative index in predicting mental health outcomes. A community sample of recently arrived Iraqi refugees (N = 298) completed the HTQ and measures of posttraumatic stress disorder (PTSD) and depression symptoms. Principal components analysis of HTQ items revealed a 5-component subtype model of trauma that accounted for more item variance than a 1-component solution. These trauma subtypes also accounted for more variance in PTSD and depression symptoms (12 and 10%, respectively) than did the cumulative trauma index (7 and 3%, respectively). Trauma subtypes provided more information than cumulative trauma in the prediction of negative mental health outcomes. Therefore, use of these subtypes may enhance the utility of the HTQ when assessing at-risk populations.

Directory of Open Access Journals (Sweden)

Marcelo T O Carlucci

Full Text Available BACKGROUND: Little information on the factors influencing intraoperative cardiac arrest and its outcomes in trauma patients is available. This survey evaluated the associated factors and outcomes of intraoperative cardiac arrest in trauma patients in a Brazilian teaching hospital between 1996 and 2009. METHODS: Cardiac arrest during anesthesia in trauma patients was identified from an anesthesia database. The data collected included patient demographics, ASA physical status classification, anesthesia provider information, type of surgery, surgical areas and outcome. All intraoperative cardiac arrests and deaths in trauma patients were reviewed and grouped by associated factors and also analyzed as totally anesthesia-related, partially anesthesia-related, totally surgery-related or totally trauma patient condition-related. FINDINGS: Fifty-one cardiac arrests and 42 deaths occurred during anesthesia in trauma patients. They were associated with male patients (P<0.001 and young adults (18-35 years (P=0.04 with ASA physical status IV or V (P<0.001 undergoing gastroenterological or multiclinical surgeries (P<0.001. Motor vehicle crashes and violence were the main causes of trauma (P<0.001. Uncontrolled hemorrhage or head injury were the most significant associated factors of intraoperative cardiac arrest and mortality (P<0.001. All cardiac arrests and deaths reported were totally related to trauma patient condition. CONCLUSIONS: Intraoperative cardiac arrest and mortality incidence was highest in male trauma patients at a younger age with poor clinical condition, mainly related to uncontrolled hemorrhage and head injury, resulted from motor vehicle accidents and violence.

Identification of Fitness Determinants during Energy-Limited Growth Arrest in Pseudomonas aeruginosa.

Basta, David W; Bergkessel, Megan; Newman, Dianne K

Microbial growth arrest can be triggered by diverse factors, one of which is energy limitation due to scarcity of electron donors or acceptors. Genes that govern fitness during energy-limited growth arrest and the extent to which they overlap between different types of energy limitation are poorly defined. In this study, we exploited the fact that Pseudomonas aeruginosa can remain viable over several weeks when limited for organic carbon (pyruvate) as an electron donor or oxygen as an electron acceptor. ATP values were reduced under both types of limitation, yet more severely in the absence of oxygen. Using transposon-insertion sequencing (Tn-seq), we identified fitness determinants in these two energy-limited states. Multiple genes encoding general functions like transcriptional regulation and energy generation were required for fitness during carbon or oxygen limitation, yet many specific genes, and thus specific activities, differed in their relevance between these states. For instance, the global regulator RpoS was required during both types of energy limitation, while other global regulators such as DksA and LasR were required only during carbon or oxygen limitation, respectively. Similarly, certain ribosomal and tRNA modifications were specifically required during oxygen limitation. We validated fitness defects during energy limitation using independently generated mutants of genes detected in our screen. Mutants in distinct functional categories exhibited different fitness dynamics: regulatory genes generally manifested a phenotype early, whereas genes involved in cell wall metabolism were required later. Together, these results provide a new window into how P. aeruginosa survives growth arrest. IMPORTANCE Growth-arrested bacteria are ubiquitous in nature and disease yet understudied at the molecular level. For example, growth-arrested cells constitute a major subpopulation of mature biofilms, serving as an antibiotic-tolerant reservoir in chronic

Time series analysis as input for clinical predictive modeling: modeling cardiac arrest in a pediatric ICU.

Science.gov (United States)

Kennedy, Curtis E; Turley, James P

Thousands of children experience cardiac arrest events every year in pediatric intensive care units. Most of these children die. Cardiac arrest prediction tools are used as part of medical emergency team evaluations to identify patients in standard hospital beds that are at high risk for cardiac arrest. There are no models to predict cardiac arrest in pediatric intensive care units though, where the risk of an arrest is 10 times higher than for standard hospital beds. Current tools are based on a multivariable approach that does not characterize deterioration, which often precedes cardiac arrests. Characterizing deterioration requires a time series approach. The purpose of this study is to propose a method that will allow for time series data to be used in clinical prediction models. Successful implementation of these methods has the potential to bring arrest prediction to the pediatric intensive care environment, possibly allowing for interventions that can save lives and prevent disabilities. We reviewed prediction models from nonclinical domains that employ time series data, and identified the steps that are necessary for building predictive models using time series clinical data. We illustrate the method by applying it to the specific case of building a predictive model for cardiac arrest in a pediatric intensive care unit. Time course analysis studies from genomic analysis provided a modeling template that was compatible with the steps required to develop a model from clinical time series data. The steps include: 1) selecting candidate variables; 2) specifying measurement parameters; 3) defining data format; 4) defining time window duration and resolution; 5) calculating latent variables for candidate variables not directly measured; 6) calculating time series features as latent variables; 7) creating data subsets to measure model performance effects attributable to various classes of candidate variables; 8) reducing the number of candidate features; 9

L1 arrest, daf-16/FoxO and nonautonomous control of post-embryonic development.

Science.gov (United States)

Kaplan, Rebecca E W; Baugh, L Ryan

Post-embryonic development is governed by nutrient availability. L1 arrest, dauer formation and aging illustrate how starvation, anticipation of starvation and caloric restriction have profound influence on C. elegans development, respectively. Insulin-like signaling through the Forkhead box O transcription factor daf-16/FoxO regulates each of these processes. We recently reported that ins-4, ins-6 and daf-28 promote L1 development from the intestine and chemosensory neurons, similar to their role in dauer development. daf-16 functions cell-nonautonomously in regulation of L1 arrest, dauer development and aging. Discrepancies in daf-16 sites of action have been reported in each context, but the consensus implicates epidermis, intestine and nervous system. We suggest technical limitations of the experimental approach responsible for discrepant results. Steroid hormone signaling through daf-12/NHR is known to function downstream of daf-16 in control of dauer development, but signaling pathways mediating cell-nonautonomous effects of daf-16 in aging and L1 arrest had not been identified. We recently showed that daf-16 promotes L1 arrest by inhibiting daf-12/NHR and dbl-1/TGF-β Sma/Mab signaling, two pathways that promote L1 development in fed larvae. We will review these results on L1 arrest and speculate on why there are so many signals and signaling centers regulating post-embryonic development.

Potentially traumatic events and mental health problems among children of Iraqi refugees: The roles of relationships with parents and feelings about school.

This study examined mental health problems among children of Iraqi refugees, most of whom were Christian. Exposure to potentially traumatic events was hypothesized to predict more symptoms of depression and traumatic stress. Moreover, youth reports of supportive relationships with parents and positive feelings about school were examined in relation to mental health problems. These promotive factors were expected to mitigate the hypothesized association between traumatic event exposure and mental health problems. Participants were 211 youth recruited from agencies and programs serving Iraqi refugees in a large metropolitan area in the United States. The hypotheses were partially supported. Youth who reported experiencing more potentially traumatic events endorsed more traumatic stress and depression symptoms. After accounting for exposure to potentially traumatic events and other covariates, youth who reported more positive feelings about school endorsed fewer symptoms of traumatic stress, and youth who reported more supportive relationships with parents endorsed fewer symptoms of depression. In addition, there was an interaction between potentially traumatic events and relationships with parents when predicting depression symptoms. Youth endorsed higher levels of depression symptoms when they reported less supportive relationships, regardless of the amount of traumatic event exposure, whereas youth endorsed lower levels of depression symptoms when they reported more supportive relationships with parents, but only at low levels of traumatic event exposure. Otherwise, the main effects were not qualified by interactions between potentially traumatic event exposure and the promotive factors. The findings from this study have implications for future research, policy, and practice with children of refugees. (PsycINFO Database Record (c) 2016 APA, all rights reserved).

Reports of race-related triathlon fatalities have raised questions regarding athlete safety. To describe death and cardiac arrest among triathlon participants. Case series. United States. Participants in U.S. triathlon races from 1985 to 2016. Data on deaths and cardiac arrests were assembled from such sources as the U.S. National Registry of Sudden Death in Athletes (which uses news media, Internet searches, LexisNexis archival databases, and news clipping services) and USA Triathlon (USAT) records. Incidence of death or cardiac arrest in USAT-sanctioned races from 2006 to 2016 was calculated. A total of 135 sudden deaths, resuscitated cardiac arrests, and trauma-related deaths were compiled; mean (±SE) age of victims was 46.7 ± 12.4 years, and 85% were male. Most sudden deaths and cardiac arrests occurred in the swim segment (n = 90); the others occurred during bicycling (n = 7), running (n = 15), and postrace recovery (n = 8). Fifteen trauma-related deaths occurred during the bike segment. Incidence of death or cardiac arrest among USAT participants (n = 4 776 443) was 1.74 per 100 000 (2.40 in men and 0.74 in women per 100 000; P < 0.001). In men, risk increased substantially with age and was much greater for those aged 60 years and older (18.6 per 100 000 participants). Death or cardiac arrest risk was similar for short, intermediate, and long races (1.61 vs. 1.41 vs. 1.92 per 100 000 participants). At autopsy, 27 of 61 decedents (44%) had clinically relevant cardiovascular abnormalities, most frequently atherosclerotic coronary disease or cardiomyopathy. Case identification may be incomplete and may underestimate events, particularly in the early study period. In addition, prerace medical history is unknown in most cases. Deaths and cardiac arrests during the triathlon are not rare; most have occurred in middle-aged and older men. Most sudden deaths in triathletes happened during the swim segment, and clinically silent cardiovascular disease

Comparison of ANSI, IEC and CSA standards durability requirements on station-type metal oxide surge arresters for EHV power systems

Hamel, A.; St-Jean, G.

1992-01-01

This paper presents an analysis of stresses applied to two actual types of station class surge arresters of the same voltage rating when tested for durability as prescribed by American (ANSI) International (IEC) and Canadian (CSA) standards for 315 kV and 734 kV power systems. The analysis which is made with an experimentally validated arrester model, reveals that the IEC duty cycle test is the most severe of all. In fact it can bring the varistors of an actual station-type arrester to a peak temperature of 129 degrees C, which leaves a margin of only 46 degrees C to its thermal stability limit at maximum continuous operating voltage (MCOV). Another actual arrester using lesser V-I-T varistor characteristics but larger varistor volume and better heat transfer from inside to outside the arrester, produces 103 degrees C which corresponds to a slightly better temperature margin of 49 degrees C. It is observed that even when using the lower performance V-I-T characteristics of the latter arrester, a thin-wall arrester housing design can improve heat transfer to a point where the margin improves to 101 degrees C on a hypothetical arrester

Mutation breeding programme was conducted to improve soybean (Glycine max. L. merrill) yield and oil Seeds were irradiation with 0,100,200,300 Gray of gamma ray Co 60 Selection of genetic variants started from M2 and continued to M8. Eight variants were selected in M8 generation that were characterized with high yield and desirable morphological characters. Preliminary comparison experiments of M9 and M10 with check variety (Lee74) were conducted at two locations (Twaitha and Lattifya). Three promising variants were selected for high yield and low percentage of seed shrinkage as compared with the check variety (Lee74) and other mutants. The same selected variants were planted in large scale comparison experiments with check variety (LEE 74) and two introduced varieties (Coker335 and Gasoy17) in two locations (Twaitha and lattifya) for two seasons (1998,1999). Variants H134 and H39 were superior in their yield components and earliness in maturity compared with the variant H226 and the other check varieties . The average yield and oil percentage in the two seasons(1998,1999) was 3195, 3115kg/ha and 18.2%, 19.3% respectively for the variants H134 and H39 compared with the yield and the percentage of oil for the check variety (Lee74) that was 2794 kg/ha and 18.3% respectively. These two variants were also superior in their protein percentage. According to these promising results of the variants H134 and H39 they were submitted for registration. They were registered under the names TAKA1 and TAKA-2 as suitable varieties for Iraqi environmental conditions. (authors) 13 refs., 5 tabs

Crack arrest studies currently being conducted by the Heavy-Section Steel Technology Program are designed to improve our understanding of the conditions contributing to the arrest of a propagating fracture in a pressure vessel. These studies are generating data spanning a wide temperature range for a variety of experimental configurations. Dynamic crack arrest parameters are back-figured from these experiments through 'generation mode' dynamic viscoplastic finite element calculations driven by the measured crack tip history input. A major approximation in these analyses, which is dictated by the practical limitations of current supercomputer hardware, is the assumption of two-dimensional plane stress conditions. Although this approximation is reasonable over most of the problem domain for many test specimen geometries, it deteriorates at locations near the crack tip due to triaxial constraint effects. This paper describes plans for a fine-grained three-dimensional computational study to investigate the importance of these near-tip triaxial constraint effects on crack tip yielding and to develop appropriate algorithms for incorporating these effects into conventional two-dimensional plane stress approximations.

Occipital lobe epilepsy of childhood includes two entities: Panayiotopoulos syndrome in pre-school children, and idiopathic childhood occipital epilepsy of Gastaut (ICOEG) in school-age children. The typical initial manifestation of the former is vomiting, and that of the latter is visual hallucinations. Ictal cardiopulmonary arrest at initial presentation has been reported for Panayiotopoulos syndrome, but not for ICOEG. We document a 7-year-old previously healthy girl who experienced an acute elemental visual hallucination of seeing insects, followed by a new-onset generalized seizure. Upon arrival at the local hospital, she was unconscious and soon thereafter, developed respiratory arrest. She was resuscitated and initiated on mechanical ventilation. An electroencephalogram taken three days after seizure cessation showed frequent occipital spikes, consistent with the diagnosis of ICOEG. The sequence of acute elementary visual hallucination followed by a motor seizure, and then witnessed respiratory arrest illustrated occurrence of life-threatening autonomic involvement at initial onset in ICOEG. We speculate that the epileptic propagation from the occipital lobes eventually compromised the respiratory center in the brainstem. The possibility of occipital lobe epilepsy should be considered in school-age children presenting with acute visual hallucination followed by respiratory arrest. Such a presentation should prompt an urgent electroencephalogram and initiation of antiepileptic treatment if indicated. Copyright © 2017 The Japanese Society of Child Neurology.

Refugees frequently experience symptoms of posttraumatic stress and depression, which impede their acculturation in the new host country where they are resettling. There are few longitudinal studies investigating predictors of mental health and acculturation during the early postmigration period. We conducted a longitudinal study of 298 Iraqi refugees, assessing them upon arrival to the U.S. and 1 year after migration. Premigration trauma was associated with increased PTSD and depressive symptoms at baseline, and with decreased acculturation 1 year later. Resilience was associated with depressive symptoms at 1-year follow-up, but not with other resettlement outcomes (PTSD symptoms, English-language skills, or acculturation). PTSD and depressive symptoms at baseline predicted the same symptoms at 1-year follow-up, but not any other resettlement outcomes. The number of chronic diseases at baseline predicted worse PTSD and depressive symptoms, acculturation, and English language skills at 1-year follow up. Postmigratory exposure to daily stressors and less social support predicted worse 1-year outcomes. Results suggest that interventions that aim to improve mental health and promote acculturation among refugees should assess their history of trauma, chronic disorders, and psychological symptoms soon after migration, and promptly provide opportunities for social support.

Previous refugee research has been unable to link pre-displacement trauma with unemployment in the host country. The current study assessed the role of pre-displacement trauma, post-displacement trauma, and the interaction of both trauma types to prospectively examine unemployment in a random sample of newly-arrived Iraqi refugees. Participants (N=286) were interviewed three times over the first two years post-arrival. Refugees were assessed for pre-displacement trauma exposure, post-displacement trauma exposure, a history of unemployment in the country of origin and host country, and symptoms of posttraumatic stress disorder (PTSD) and depression. Analyses found that neither pre-displacement nor post-displacement trauma independently predicted unemployment 2 years post-arrival; however, the interaction of pre and post-displacement trauma predicted 2-year unemployment. Refugees with high levels of both pre and post-displacement trauma had a 91% predicted probability of unemployment, whereas those with low levels of both traumas had a 20% predicted probability. This interaction remained significant after controlling for sociodemographic variables and mental health upon arrival to the U.S. Resettlement agencies and community organizations should consider the interactive effect of encountering additional trauma after escaping the hardships of the refugee's country of origin.

Effect of caffeine on radiation-induced mitotic delay: delayed expression of G2 arrest

International Nuclear Information System (INIS)

Rowley, R.; Zorch, M.; Leeper, D.B.

1984-01-01

In the presence of 5 mM caffeine, irradiated (1.5 Gy) S and G 2 cells progressed to mitosis in register and without arrest in G 2 . Caffeine (5 mM) markedly reduced mitotic delay even after radiation doses up to 20 Gy. When caffeine was removed from irradiated (1.5 Gy) and caffeine-treated cells, a period of G 2 arrest followed, similar in length to that produced by radiation alone. The arrest expressed was independent of the duration of the caffeine treatment for exposures up to 3 hr. The similarity of the response to the cited effects of caffeine on S-phase delay suggests a common basis for delay induction in S and G 2 phases

Rotavirus replication is correlated with S/G2 interphase arrest of the host cell cycle.

Directory of Open Access Journals (Sweden)

Full Text Available In infected cells rotavirus (RV replicates in viroplasms, cytosolic structures that require a stabilized microtubule (MT network for their assembly, maintenance of the structure and perinuclear localization. Therefore, we hypothesized that RV could interfere with the MT-breakdown that takes place in mitosis during cell division. Using synchronized RV-permissive cells, we show that RV infection arrests the cell cycle in S/G2 phase, thus favoring replication by improving viroplasms formation, viral protein translation, and viral assembly. The arrest in S/G2 phase is independent of the host or viral strain and relies on active RV replication. RV infection causes cyclin B1 down-regulation, consistent with blocking entry into mitosis. With the aid of chemical inhibitors, the cytoskeleton network was linked to specific signaling pathways of the RV-induced cell cycle arrest. We found that upon RV infection Eg5 kinesin was delocalized from the pericentriolar region to the viroplasms. We used a MA104-Fucci system to identify three RV proteins (NSP3, NSP5, and VP2 involved in cell cycle arrest in the S-phase. Our data indicate that there is a strong correlation between the cell cycle arrest and RV replication.

Metazoan operons accelerate recovery from growth arrested states

Summary Existing theories explain why operons are advantageous in prokaryotes, but their occurrence in metazoans is an enigma. Nematode operon genes, typically consisting of growth genes, are significantly up-regulated during recovery from growth-arrested states. This expression pattern is anti-correlated to non-operon genes consistent with a competition for transcriptional resources. We find that transcriptional resources are initially limiting during recovery, and that recovering animals are highly sensitive to any additional decrease in transcriptional resources. Operons become advantageous because by clustering growth genes into operons, fewer promoters compete for the limited transcriptional machinery, effectively increasing the concentration of transcriptional resources, and accelerating recovery. Mathematical modeling reveals how a moderate increase in transcriptional resources can substantially enhance transcription rate and recovery. This design principle occurs in different nematodes and the chordate C. intestinalis. As transition from arrest to rapid growth is shared by many metazoans, operons could have evolved to facilitate these processes. PMID:21663799

Attention deficit hyperactivity disorder and arrest history: Differential association of clinical characteristics by sex.

Kolla, Nathan J; van der Maas, Mark; Erickson, Patricia G; Mann, Robert E; Seeley, Jane; Vingilis, Evelyn

Attention deficit hyperactivity disorder (ADHD) is often cited as a risk factor for criminality. However, many studies do not take other criminogenic variables into account when reporting on this relationship. It is even less clear whether models that include ADHD as a potential risk factor for criminality consider the importance of sex differences. To answer this question, we collected data from a telephone population survey sampling adults over the age of 18 years in the province of Ontario, Canada (final sample size = 5196). Respondents were screened for ADHD using the Adult ADHD Self-Report Version 1.1 Screener (ASRS-V1.1) and four extra items. Problematic drinking was assessed using the Alcohol Use Disorders Identification Test (AUDIT), while cannabis misuse was evaluated using the Alcohol, Smoking and Substance Involvement Screening Test (ASSIST). The Antisocial Personality Disorder Scale from the Mini-International Neuropsychiatric Interview provided a measure of previous conduct disorder symptoms and the 12-item General Health Questionnaire screening procedure was used to gauge general distress. History of arrest was self-reported. Three separate logistic regression analyses (entire sample, male only, and female only) were applied to estimate the association of the foregoing variables with arrest history. In the combined sample, conduct disorder symptoms, problem alcohol use, and problem cannabis use all predicted history of arrest. With regard to the male sample, conduct disorder symptoms, elevated AUDIT and ASSIST scores, and general distress were associated with an arrest history. For the female subsample, only conduct disorder symptoms and problematic cannabis use showed a relationship with criminality. To summarize, ADHD did not predict history of arrest for either subsample or the combined sample. When comparing males and females, conduct disorder symptoms and cannabis misuse exerted stronger effects on history of arrest for females than males

Intracellular pH in Gastric and Rectal Tissue Post Cardiac Arrest

Science.gov (United States)

Fisher, Elaine M.; Steiner, Richard P.; LaManna, Joseph C.

We directly measured pHi using the pH sensitive dye, neutral red. We defined pHi for rectal and gastric tissue in whole tissue and by layer under control and arrest conditions. Fifteen minutes of arrest was not sufficient time to alter the pHi at the rectal or gastric site. On initial inspection, the stomach may be more sensitive to ischemic changes than the rectum. Understanding the mechanism by which PCO2 generation is used to track clinical changes is vital to the early detection of tissue dysoxia in order to effectively treat and manage critically ill patients.

The objective of this study is to determine the effect of neutron irradiation on the shift and shape of the lower-bound curve to crack-arrest data. Two submerged-arc welds with copper contents of 0.23 and 0.31 wt % were commercially fabricated in 220-mm-thick plate. Crack-arrest specimens fabricated from these welds were irradiated at a nominal temperature of 288 degree C to an average fluence of 1.9 x 10 19 neutrons/cm 2 (>1 MeV). A preliminary evaluation of the results shows that the neutron-irradiation induced crack-arrest toughness temperature shift is about the same as the Charpy V-notch impact temperature shift at the 41-J energy level. The shape of the lower-bound curves, (for the range of test temperatures covered), compared to those of the ASME K Ia -curve did not seem to have been altered by irradiation. 10 refs., 9 figs., 7 tabs

Four typical types of green shrubs of Beijing (Euonymus japonicus, Buxus microphylla, Berberis thunbergii cv. atropurpurea, Taxus cuspidate cv. nana) were selected to study their capacities in adsorbing and arresting PM2.5 using both field observations and air chamber simulations. Concurrently, in order to analyze the pollution characteristics of Beijing in winter and spring, the PM2.5 concentrations of December 2012 to May 2013 were collected. Experimental results showed that: From the gas chamber experiments, the ability to adsorb and arrest PM2.5 was in the order of Berberis thunbergii cv. atropurpurea > Buxus microphylla > Taxus cuspidate cv. nana > Euonymus japonicus, mainly due to the differences in leaf characteristics; Outside measurement results showed that the ability to adsorb and arrest PM2.5 was ranked as Buxus microphylla > Berberis thunbergii cv. atropurpurea > Taxus cuspidate cv. nana > Euonymus japonicus. Chamber simulation and outdoor observation showed that Buxus microphylla and Berberis thunbergii cv. atropurpurea had strong ability to adsorb and arrest PM2.5; Meanwhile, the slight differences between the chamber simulation and outdoor observation results might be related to plant structure. Compared to tree species, the planting condition of shrub species was loose, and it greened quickly; By analyzing the Beijing PM2.5 concentration values in winter and spring, it was found that the PM2.5 concentration was particularly high in the winter of Beijing, and evergreen shrubs maintained the ability to adsorb and arrest PM2.5.

Co-Occurring Risk Factors for Arrest among Persons with Opioid Abuse and Dependence: Implications for Developing Interventions to Limit Criminal Justice Involvement

Persons who abuse opioids or are dependent on opioids are at elevated risk for arrest. Co-occurring behavioral health problems may exacerbate that risk, although the extent of any such increase has not been described. This study examines such risk factors among 40,238 individuals with a diagnosis of opioid abuse or dependence who were enrolled in the Massachusetts Medicaid program in 2010. Medicaid data were merged with statewide arrest data to assess the effects of co-existing mental illness, substance abuse, and previous arrests on arrest during 2010. Persons with serious mental illnesses (psychotic and bipolar disorders) and those with two or more pre-2010 arrests had significantly increased greater odds of arrest. We believe this to be the first study examining effects of co-occurring risk factors on arrest in a large population with opioid dependency/abuse. These findings identify predictors of arrest that could be used to design interventions targeting specific co-occurring risk factors. PMID:25012550

Astronomy in Iraq

The history of modern Iraqi astronomy is reviewed. During the early 1970's Iraqi astronomy witnessed significant growth through the introduction of the subject at university level and extensively within the school curriculum. In addition, astronomy was popularised in the media, a large planetarium was built in Baghdad, plus a smaller one in Basra. Late 1970 witnessed the construction of the Iraqi National Observatory at Mount Korek in Iraqi Kurdistan. The core facilities of the Observatory included 3.5-meter and 1.25-meter optical telescopes, and a 30-meter radio telescope for millimetre wavelength astronomy. The Iraqi Astronomical Society was founded and Iraq joined the IAU in 1976. During the regime of Saddam Hussain in the 1980's, the Observatory was attacked by Iranian artillery during the Iraq-Iran war, and then again during the second Gulf war by the US air force. Years of sanctions during the 1990's left Iraq cut off from the rest of the international scientific community. Subscriptions to astronomical journals were halted and travel to conferences abroad was virtually non-existent. Most senior astronomers left the country for one reason or another. Support from expatriate Iraqi astronomers existed (and still exists) however, this is not sufficient. Recent changes in Iraq, and the fall of Saddam's regime, has meant that scientific communication with the outside world has resumed to a limited degree. The Ministry of Higher Education in Baghdad, Baghdad University and the Iraqi National Academy of Science, have all played active roles in re-establishing Iraqi astronomy and re-building the damaged Observatory at Mount Korek. More importantly the University of Sallahudin in Erbil, capital of Iraqi Kurdistan, has taken particular interest in astronomy and the Observatory. Organized visits to the universities, and also to the Observatory, have given us a first-hand assessment of the scale of the damage to the Observatory, as well as the needs of astronomy teaching

Cardiopulmonary resuscitation (CPR) performed by bystanders is associated with increased survival rates among persons with out-of-hospital cardiac arrest. We investigated whether rates of bystander-initiated CPR could be increased with the use of a mobile-phone positioning system that could instantly locate mobile-phone users and dispatch lay volunteers who were trained in CPR to a patient nearby with out-of-hospital cardiac arrest. We conducted a blinded, randomized, controlled trial in Stockholm from April 2012 through December 2013. A mobile-phone positioning system that was activated when ambulance, fire, and police services were dispatched was used to locate trained volunteers who were within 500 m of patients with out-of-hospital cardiac arrest; volunteers were then dispatched to the patients (the intervention group) or not dispatched to them (the control group). The primary outcome was bystander-initiated CPR before the arrival of ambulance, fire, and police services. A total of 5989 lay volunteers who were trained in CPR were recruited initially, and overall 9828 were recruited during the study. The mobile-phone positioning system was activated in 667 out-of-hospital cardiac arrests: 46% (306 patients) in the intervention group and 54% (361 patients) in the control group. The rate of bystander-initiated CPR was 62% (188 of 305 patients) in the intervention group and 48% (172 of 360 patients) in the control group (absolute difference for intervention vs. control, 14 percentage points; 95% confidence interval, 6 to 21; PCPR was associated with significantly increased rates of bystander-initiated CPR among persons with out-of-hospital cardiac arrest.

Withholding or termination of resuscitation in pediatric out-of-hospital traumatic cardiopulmonary arrest.

Fallat, Mary E

2014-04-01

This multiorganizational literature review was undertaken to provide an evidence base for determining whether or not recommendations for out-of-hospital termination of resuscitation could be made for children who are victims of traumatic cardiopulmonary arrest. Although there is increasing acceptance of out-of-hospital termination of resuscitation for adult traumatic cardiopulmonary arrest when there is no expectation of a good outcome, children are routinely excluded from state termination-of-resuscitation protocols. The decision to withhold resuscitative efforts in a child under specific circumstances (decapitation or dependent lividity, rigor mortis, etc) is reasonable. If there is any doubt as to the circumstances or timing of the traumatic cardiopulmonary arrest, under the current status of limiting termination of resuscitation in the field to persons older than 18 years in most states, resuscitation should be initiated and continued until arrival to the appropriate facility. If the patient has arrested, resuscitation has already exceeded 30 minutes, and the nearest facility is more than 30 minutes away, involvement of parents and family of these children in the decision-making process with assistance and guidance from medical professionals should be considered as part of an emphasis on family-centered care, because the evidence suggests that either death or a poor outcome is inevitable.

To analyze the relationship between previous severity of illness, lactic acid, creatinine and inotropic index with mortality of in-hospital cardiac arrest (CA) in children, and the value of a prognostic index designed for adults. The study included total of 44 children aged from 1 month to 18 years old who suffered a cardiac arrest while in hospital. The relationship between previous severity of illness scores (PRIMS and PELOD), lactic acid, creatinine, treatment with vasoactive drugs, inotropic index with return of spontaneous circulation and survival at hospital discharge was analyzed. The large majority (90.3%) of patients had a return of spontaneous circulation, and 59% survived at hospital discharge. More than two-thirds (68.2%) were treated with inotropic drugs at the time of the CA. The patients who died had a higher lactic acid before the CA (3.4 mmol/L) than survivors (1.4 mmol/L), P=.04. There were no significant differences in PRIMS, PELOD, creatinine, inotropic drugs, and inotropic index before CA between patients who died and survivors. A high lactic acid previous to cardiac arrest could be a prognostic factor of in-hospital cardiac arrest in children. Copyright © 2013 Asociación Española de Pediatría. Published by Elsevier Espana.

Extensive survey of meiotic metaphase II arrest during oocyte maturation in vertebrates revealed that the mitogen-activated protein kinase (MAPK) pathway regulated by the c-mos proto-oncogene product, Mos, has an essential role in cytostatic activity, termed cytostatic factor (CSF). In contrast, little is known in invertebrates in which meiotic arrest occurs in most cases at metaphase I (MI arrest). A parthenogenetic insect, the sawfly Athalia rosae, in which artificial egg activation is practicable, has advantages to investigate the mechanisms of MI arrest. Both the MAPK/extracellular signal-regulated protein kinase kinase (MEK) and MAPK were phosphorylated and maintained active in MI-arrested sawfly eggs, whereas they were dephosphorylated soon after egg activation. Treatment of MI-arrested eggs with U0126, an inhibitor of MEK, resulted in dephosphorylation of MAPK and MI arrest was resumed. The sawfly c-mos gene orthologue encoding a serine/threonine kinase was cloned and analyzed. It was expressed in nurse cells in the ovaries. To examine CSF activity of the sawfly Mos, synthesized glutathione S-transferase (GST)-fusion sawfly Mos protein was injected into MI-resumed eggs in which MEK and MAPK were dephosphorylated. Both MEK and MAPK were phosphorylated again upon injection. In these GST-fusion sawfly Mos-injected eggs subsequent mitotic (syncytial) divisions were blocked and embryonic development was ceased. These results demonstrated that the MEK-MAPK pathway was involved in maintaining CSF arrest in sawfly eggs and Mos functioned as its upstream regulatory molecule.

Initiation and arrest - two approaches to pressure vessel safety

International Nuclear Information System (INIS)

Brumovsky, M.; Filip, R.; Stepanek, S.

1976-01-01

The safety analysis is described of the reactor pressure vessel related to brittle fracture based on the fracture mechanics theory using two different approximations, i.e., the Crack Arrest Temperature (CAT) or Nil Ductility Temperature (NDT), and fracture toughness. The variation of CAT with stress was determined for different steel specimens of 120 to 200 mm in thickness. A diagram is shown of CAT variation with stress allowing the determination of crack arrest temperature for all types of commonly used steels independently of the NDT initial value. The diagram also shows that the difference between fracture transition elastic (FTE) and NDT depends on the type of material and determines the value of the ΔTsub(sigma) factor typical of the safety coefficient. The so-called fracture toughness reference value Ksub(IR) is recommended for the computation of pressure vessel criticality. Also shown is a defect analysis diagram which may be used for the calculation of pressure vessel safety prior to and during operation and which may also be used in making the decision on what crack sizes are critical, what cracks may be arrested and what cracks are likely to expand. The diagram is also important for the fact that it is material-independent and may be employed for the estimates of pre-operational and operational inspections and for pressure vessel life prediction. It is generally applicable to materials of greater thickness in the region where the validity of linear elastic fracture mechanics is guaranteed. (J.P.)

Diacylglycerol kinase zeta negatively regulates CXCR4-stimulated T lymphocyte firm arrest to ICAM-1 under shear flow.

T lymphocyte arrest within microvasculature is an essential process in immune surveillance and the adaptive immune response. Integrins and chemokines coordinately regulate when and where T cells stop under flow via chemokine-triggered inside-out activation of integrins. Diacylglycerol kinases (DGKs) regulate the levels of diacylglycerol (DAG) which in turn determine the activation of guanine nucleotide exchange factors (GEFs) and Ras proximity 1 (Rap1) molecules crucial to the activation of integrin lymphocyte function-associated antigen 1 (LFA-1). However, how the level of DGK regulates chemokine-stimulated LFA-1-mediated T cell arrest under flow is unknown. Using a combination of experiment and computational modeling, we demonstrate that DGKζ is a crucial regulator of CXCL12-triggered T cell arrest on surfaces presenting inter-cellular adhesion molecule 1 (ICAM-1). Using flow chamber assays, we found that the deficiency of DGKζ in T cells significantly increased firm arrest to ICAM-1-coated substrates and shortened the time to stop without altering the rolling velocity. These results suggest that DGKζ levels affect LFA-1-mediated T cell firm arrest, but not P-selectin-mediated rolling during CXCL12 stimulation. We accurately simulated the role of DGKζ in firm arrest of T cells computationally using an Integrated-Signaling Adhesive Dynamics (ISAD). In the absence of DGK catalytic reaction, the model cells rolled for a significantly shorter time before arrest, compared to when DGK molecules were present. Predictions of our model for T cell arrest quantitatively match experimental results. Overall these results demonstrate that DGKζ is a negative regulator of CXCL12-triggered inside-out activation of LFA-1 and firm adhesion of T cells under shear flow.

Arrested of coalescence of emulsion droplets of arbitrary size

Mbanga, Badel L.; Burke, Christopher; Blair, Donald W.; Atherton, Timothy J.

2013-03-01

With applications ranging from food products to cosmetics via targeted drug delivery systems, structured anisotropic colloids provide an efficient way to control the structure, properties and functions of emulsions. When two fluid emulsion droplets are brought in contact, a reduction of the interfacial tension drives their coalescence into a larger droplet of the same total volume and reduced exposed area. This coalescence can be partially or totally hindered by the presence of nano or micron-size particles that coat the interface as in Pickering emulsions. We investigate numerically the dependance of the mechanical stability of these arrested shapes on the particles size, their shape anisotropy, their polydispersity, their interaction with the solvent, and the particle-particle interactions. We discuss structural shape changes that can be induced by tuning the particles interactions after arrest occurs, and provide design parameters for the relevant experiments.

The objective of this study was to analyze the characteristic and the prognostic factors of in-hospital pediatric cardiac arrest (CA) in a public hospital Honduras. A prospective observational study was performed on pediatric in-hospital CA as a part of a multicenter international study. One hundred forty-six children were studied. The primary end point was survival at hospital discharge. Univariate and multivariate logistic regression analyses were performed to assess the influence of each factor on mortality. Cardiac arrest occurred in the emergency department in 66.9%. Respiratory diseases and sepsis were predominant causes of CA. Return of spontaneous circulation was achieved in 60% of patients, and 22.6% survived to hospital discharge. The factors related with mortality were nonrespiratory cause of CA (odds ratio [OR], 2.55; P = 0.045), adrenaline administration (OR, 4.96; P = 0.008), and a duration of cardiopulmonary resuscitation more than 10 minutes (OR, 3.40; P = 0.012). In-hospital CA in children in a developing country has low survival. Patients with nonrespiratory causes and those who need adrenaline administration and prolonged resuscitation had worse prognosis.

As a great number of overvoltage arresters used by France Telecom to protect its telecommunication network against disturbing voltages (notably lightning) contain radio-elements, this report aims at assessing dose levels and associated risks for employees exposed to radioactive overvoltage arrester when setting them up, exploiting installations containing such arresters, or when removing them. After a presentation of these devices, a modelling of activities and geometries is proposed, as well as computation tools. Different scenarios and exposure situations are considered. As far as risks are concerned, after a recall on cancers and ionizing radiation, and on the exposure of France Telecom employees, the report comments the knowledge on radio-induced cancers; notably breast cancer, skin cancer, and mouth and pharynx cancers

Background Cardiac arrests are a major public health concern worldwide. The extent and types of randomized controlled trials (RCTs) – our most reliable source of clinical evidence – conducted in these high-risk patients over recent years are largely unknown. Methods and Results We performed a systematic review, identifying all RCTs published in PubMed, EMBASE, Scopus, Web of Science, and the Cochrane Library from 1995 to 2014 that focused on acute treatment of non-traumatic cardiac arrest in adults. We then extracted data on the setting of study populations, types and timing of interventions studied, risk of bias, outcomes reported and how these factors have changed over time. Over this twenty-year period, 92 RCTs were published containing 64,309 patients (median, 225.5 per trial). Of these, 81 RCTs (88.0%) involved out-of-hospital cardiac arrest whereas 4 (4.3%) involved in-hospital cardiac arrest and 7 (7.6%) included both. Eighteen RCTs (19.6%) were performed in the U.S., 68 (73.9%) were performed outside the U.S., and 6 (6.5%) were performed in both settings. Thirty-eight RCTs (41.3%) evaluated drug therapy, 39 (42.4%) evaluated device therapy, and 15 (16.3%) evaluated protocol improvements. Seventy-four RCTs (80.4%) examined interventions during the cardiac arrest, 15 (16.3%) examined post-cardiac arrest treatment, and 3 (3.3%) studied both. Overall, reporting of risk of bias was limited. The most common outcome reported was ROSC: 86 (93.5%) with only 22 (23.9%) reporting survival beyond 6 months. Fifty-three RCTs (57.6%) reported global ordinal outcomes whereas 15 (16.3%) reported quality-of-life. RCTs in the last 5 years were more likely to be focused on protocol improvement and post-cardiac arrest care. Conclusions Important gaps in RCTs of cardiac arrest treatments exist, especially those examining in-hospital cardiac arrest, protocol improvement, post-cardiac arrest care, and long-term or quality-of-life outcomes.

Full Text Available The unprecedented development of criminality at the social and economical levels, the tendency toglobalize some categories of crimes, of maximum gravity, as terrorism, armament traffic, drug traffic orhuman traffic, have determined the world states to undertake specific measures to prevent, combat and finallyreduce it. The first and most important measure taken by the Europe’s Council, regarding the intensificationof judicial cooperation in criminal matters was the adoption of the European Convention on extradition, inParis on 13 December 1957, completed by the two Additional Protocols in Strasbourg, on 15 October 1975and 17 March 1978. In this context, the release of the Council’s Framework Decision on 13 June 2002 on theEuropean arrest warrant and the procedures of delivery among the member states (2002/584/JAI representeda natural decision, with the purpose of contributing at ensuring a free, secure and just European space. TheEuropean arrest warrant is a judicial decision through which a competent judicial authority of a EuropeanUnion member state solicits the arrest and delivery by another member state, in order to proceed to theprosecution, trial or execution of a penalty or safety measure that is privative of freedom.

Passive quench arrest by a chimney induced deluge at every quench front

International Nuclear Information System (INIS)

Sydoriak, S.G.

1984-01-01

This chapter describes a magnet in which a growing quench stops itself spontaneously within a fraction of one winding turn because vapor in quench-heated channels generates a progressively increasing downflow of liquid in advance of each of the quench fronts. The downflow eventually becomes a deluge as the quench grows. The design of the multiple arrested quench magnet is discussed. It is shown how to construct a magnet so that if an arrested quench arises when it is at its highest operating current, peak nucleate boiling will exist in all quenching channels

Highlights: ► Iraqi synthetic zeolite type Na-A has been suggested as ion exchange material to treat cobalt-60 in radioactive liquid waste which came from neutron activation for corrosion products. ► The ability of Na-A zeolite to remove cobalt from wastewater was checked for high cobalt concentration (822 mg/L) in addition to low cobalt concentration in the source sample (0.093 mg/L). ► The effects of important design variables on the zeolite column performance were studied these include initial concentration, flow rate, and bed depth. ► The experimental results show that high sorption capacity can be obtained at high influent concentration, low flow rate, and high bed depth. ► Higher column performance was obtained at higher bed depth. - Abstract: Iraqi synthetic zeolite type Na-A has been suggested as ion exchange material to treat cobalt-60 in radioactive liquid waste which came from neutron activation for corrosion products. Batch experiments were conducted to find out the equilibrium isotherm for source sample .The equilibrium isotherm for radioactive cobalt in the source sample showed unfavorable type, while the equilibrium isotherm for the total cobalt (the radioactive and nonradioactive cobalt) in the source sample showed a favorable type. The ability of Na-A zeolite to remove cobalt from wastewater was checked for high cobalt concentration (822 mg/L) in addition to low cobalt concentration in the source sample (0.093 mg/L). A good fitting for the experimental data with Langmuir equilibrium model was observed. Langmuir constant qm which is related to monolayer adsorption capacity for low and high cobalt concentration was determined to be 0.021 and 140 mg/g zeolite . The effects of important design variables on the zeolite column performance were studied these include initial concentration, flow rate, and bed depth. The experimental results have shown that high sorption capacity can be obtained at high influent concentration, low flow rate, and

Despite wide dissemination of automated external defibrillators (AEDs), bystander defibrillation rates remain low. We aimed to investigate how route distance to the nearest accessible AED was associated with probability of bystander defibrillation in public and residential locations. We used data from the nationwide Danish Cardiac Arrest Registry and the Danish AED Network to identify out-of-hospital cardiac arrests and route distances to nearest accessible registered AED during 2008-2013. The association between route distance and bystander defibrillation was described using restricted cubic spline logistic regression. We included 6971 out-of-hospital cardiac arrest cases. The proportion of arrests according to distance in meters (≤100, 101-200, >200) to the nearest accessible AED was: 4.6% (n=320), 5.3% (n=370), and 90.1% (n=6281), respectively. For cardiac arrests in public locations, the probability of bystander defibrillation at 0, 100 and 200m from the nearest AED was 35.7% (95% confidence interval 28.0%-43.5%), 21.3% (95% confidence interval 17.4%-25.2%), and 13.7% (95% confidence interval 10.1%-16.8%), respectively. The corresponding numbers for cardiac arrests in residential locations were 7.0% (95% confidence interval -2.1%-16.1%), 1.5% (95% confidence interval 0.002%-2.8%), and 0.9% (95% confidence interval 0.0005%-1.7%), respectively. In public locations, the probability of bystander defibrillation decreased rapidly within the first 100m route distance from cardiac arrest to nearest accessible AED whereas the probability of bystander defibrillation was low for all distances in residential areas.

Bystander-delivered defibrillation (hereinafter referred to as bystander defibrillation) of patients with out-of-hospital cardiac arrests (OHCAs) remains limited despite the widespread dissemination of automated external defibrillators (AEDs). To examine calendar changes in bystander defibrillation and subsequent survival according to a public or a residential location of the cardiac arrest after nationwide initiatives in Denmark to facilitate bystander-mediated resuscitative efforts, including bystander defibrillation. This nationwide study identified 18 688 patients in Denmark with first-time OHCA from June 1, 2001, to December 31, 2012, using the Danish Cardiac Arrest Registry. Patients had a presumed cardiac cause of arrest that was not witnessed by emergency medical services personnel. Data were analyzed from April 1, 2015, to December 10, 2016. Nationwide initiatives to facilitate bystander resuscitative efforts, including bystander defibrillation, consisted of resuscitation training of Danish citizens, dissemination of on-site AEDs, foundation of an AED registry linked to emergency medical dispatch centers, and dispatcher-assisted guidance of bystander resuscitation efforts. The proportion of patients who received bystander defibrillation according to the location of the cardiac arrest and their subsequent 30-day survival. Of the 18 688 patients with OHCAs (67.8% men and 32.2% women; median [interquartile range] age, 72 [62-80] years), 4783 (25.6%) had a cardiac arrest in a public location and 13 905 (74.4%) in a residential location. The number of registered AEDs increased from 141 in 2007 to 7800 in 2012. The distribution of AED location was consistently skewed in favor of public locations. Bystander defibrillation increased in public locations from 3 of 245 (1.2%; 95% CI, 0.4%-3.5%) in 2001 to 78 of 510 (15.3%; 95% CI, 12.4%-18.7%) in 2012 (P bystander defibrillation increased in public locations from 8.3% (95% CI, 1.5%-35.4%) in 2001/2002 to 57

Patient survival after cardiac arrest can be improved significantly with prompt and effective resuscitative care. This systematic review analyzes the basic life support factors that improve survival outcome, including chest compression technique and rapid defibrillation of shockable rhythms. For patients who are successfully resuscitated, comprehensive postresuscitation care is essential. Targeted temperature management is recommended for all patients who remain comatose, in addition to careful monitoring of oxygenation, hemodynamics, and cardiac rhythm. Management of cardiac arrest in circumstances such as pregnancy, pulmonary embolism, opioid overdose and other toxicologic causes, hypothermia, and coronary ischemia are also reviewed.

The effect of bystander interventions on long-term functional outcomes among survivors of out-of-hospital cardiac arrest has not been extensively studied. We linked nationwide data on out-of-hospital cardiac arrests in Denmark to functional outcome data and reported the 1-year risks of anoxic brain damage or nursing home admission and of death from any cause among patients who survived to day 30 after an out-of-hospital cardiac arrest. We analyzed risks according to whether bystander cardiopulmonary resuscitation (CPR) or defibrillation was performed and evaluated temporal changes in bystander interventions and outcomes. Among the 2855 patients who were 30-day survivors of an out-of-hospital cardiac arrest during the period from 2001 through 2012, a total of 10.5% had brain damage or were admitted to a nursing home and 9.7% died during the 1-year follow-up period. During the study period, among the 2084 patients who had cardiac arrests that were not witnessed by emergency medical services (EMS) personnel, the rate of bystander CPR increased from 66.7% to 80.6% (Pbystander defibrillation increased from 2.1% to 16.8% (Pbystander CPR was associated with a risk of brain damage or nursing home admission that was significantly lower than that associated with no bystander resuscitation (hazard ratio, 0.62; 95% confidence interval [CI], 0.47 to 0.82), as well as a lower risk of death from any cause (hazard ratio, 0.70; 95% CI, 0.50 to 0.99) and a lower risk of the composite end point of brain damage, nursing home admission, or death (hazard ratio, 0.67; 95% CI, 0.53 to 0.84). The risks of these outcomes were even lower among patients who received bystander defibrillation as compared with no bystander resuscitation. In our study, we found that bystander CPR and defibrillation were associated with risks of brain damage or nursing home admission and of death from any cause that were significantly lower than those associated with no bystander resuscitation.

Successful resuscitation of a pregnant woman undergoing cardiac arrest and survival of the fetus require prompt, high-quality cardiopulmonary resuscitation. The objective of this observational study was to assess management of maternal cardiac arrest by anesthesia residents using high-fidelity simulation and compare subsequent performance following either didactic teaching or electronic learning (e-learning). Twenty anesthesia residents were randomized to receive either didactic teaching (Didactic group, n = 10) or e-learning (Electronic group, n = 10) on maternal cardiac arrest. Baseline management skills were tested using high-fidelity simulation, with repeat simulation testing one month after their teaching intervention. The time from cardiac arrest to start of perimortem Cesarean delivery (PMCD) was measured, and the technical and nontechnical skills scores between the two teaching groups were compared. The median [interquartile range] time to PMCD decreased after teaching, from 4.5 min [3.4 to 5.1 min] to 3.5 min [2.5 to 4.0 min] (P = 0.03), although the change within each group was not statistically significant (Didactic group 4.9 to 3.8 min, P = 0.2; Electronic group 3.9 to 2.5 min, P = 0.07; Didactic group vs Electronic group, P = 1.0). Even after teaching, only 65% of participants started PMCD within four minutes. Technical and nontechnical skills scores improved after teaching in both groups, and there were no differences between the groups. There are gaps in the knowledge and implementation of resuscitation protocols and the recommended modifications for pregnancy among residents. Teaching can improve performance during management of maternal cardiac arrest. Electronic learning and didactic teaching offer similar benefits.

Use of force [UOF] by police can result in serious injuries and fatalities. The risk of significant injuries associated with different force modalities is poorly defined. We sought to determine the incidence of police UOF and compare the likelihood of significant injury with different force modalities. A prospective multicenter observational study of all UOF incidents was conducted via mandatory UOF investigations at three mid-sized police agencies over a two year period. Expert physicians reviewed police and medical records to determine injury severity using a priori injury severity stratification criteria. There were 893 UOF incidents, representing a UOF rate of 0.086% of 1,041,737 calls for service (1 in 1167) and 0.78% of 114,064 criminal arrests(1 in 128). Suspects were primarily young (mean age, 31 years; range, 12-86 years) males (89%). The 1,399 force utilizations included unarmed physical force (n = 710, 51%), CEWs (504, 30%), chemical (88, 6.3%), canines (47, 3.4%), impact weapons (9, 0.6%), kinetic impact munitions (8, 0.6%), firearms (6, 0.4%), and other (27, 1.9%). Among 914 suspects, 898 (98%) sustained no or mild injury after police UOF. Significant (moderate or severe) injuries occurred in 16 (1.8%) subjects. Logistic regression analysis shows these are most associated with firearm and canine use. There was one fatality (0.1%) due to gunshots. No significant injuries occurred among 504 CEW uses (0%; 95% confidence interval, 0.0-0.9%). Of the 355 suspects transported to a medical facility, 78 (22%) were hospitalized. The majority of hospitalizations were unrelated to UOF (n = 59, 76%), whereas a minority (n = 19, 24%) were due to injuries related to police UOF. Police UOF is rare. When force is used officers most commonly rely on unarmed physical force and CEWs. Significant injuries are rare. Transport for medical evaluation is a poor surrogate for significant injury due to UOF. Epidemiological, level II.
