    2008-01-01

    This review of Professor Marcos Cueto's Cold War Deadly Fevers: Malaria Eradication in Mexico, 1955–1975 discusses some of the historical, sociological, political and parasitological topics included in Dr. Cueto's superbly well-informed volume. The reviewer, a parasitologist, follows the trail illuminated by Dr. Cueto through the foundations of the malaria eradication campaign; the release in Mexico of the first postage stamp in the world dedicated to malaria control; epidemiological facts on malarial morbidity and mortality in Mexico when the campaign began; the emergence of problem areas that impeded eradication; considerations on mosquitoes and malaria transmission in Mexico; the role of business and society in malaria eradication; the results of the campaign; the relationship between malaria and poverty; and the parasitological lessons to be learned from the history of malaria eradication campaigns. Dr. Cueto's excellent and well-informed exploration of malaria – not merely as a disease but as a social, economic and human problem – makes this book required reading.

  2. Control of typhus fever in Finland during World War II.

    The article describes the measures taken against the threat of typhus epidemic in Finland during the Second World War. Comparisons between countries at war and their different typhus prevention methods are made. The main method of typhus prevention in Finland consisted of regular sauna bathing, which was culturally acceptable and very efficient when combined with heating of the clothing. The Finnish troops remained virtually louse-free by ecological and traditional methods, and thus the spread of typhus fever in the army could be prevented.

  3. The centenary of the discovery of trench fever, an emerging infectious disease of World War 1.

    In 1915, a British medical officer on the Western Front reported on a soldier with relapsing fever, headache, dizziness, lumbago, and shin pain. Within months, additional cases were described, mostly in frontline troops, and the new disease was called trench fever. More than 1 million troops were infected with trench fever during World War 1, with each affected soldier unfit for duty for more than 60 days. Diagnosis was challenging, because there were no pathognomonic signs and symptoms and the causative organism could not be cultured. For 3 years, the transmission and cause of trench fever were hotly debated. In 1918, two commissions identified that the disease was louse-borne. The bacterium Rickettsia quintana was consistently found in the gut and faeces of lice that had fed on patients with trench fever and its causative role was accepted in the 1920s. The organism was cultured in the 1960s and reclassified as Bartonella quintana; it was also found to cause endocarditis, peliosis hepatis, and bacillary angiomatosis. Subsequently, B quintana infection has been identified in new populations in the Andes, in homeless people in urban areas, and in individuals with HIV. The story of trench fever shows how war can lead to the recrudescence of an infectious disease and how medicine approached an emerging infection a century ago. Copyright © 2016 Elsevier Ltd.

    After description of the medical institutions and epidemiological situations of the Austro-Hungarian army in World War I the provisions against spotted fever focused on louse control are discussed. The letter specified for the army had to be adjusted for the local populations. 1915 in the k.u.k. military service in Galicia Edmund Weil and Arthur Felix cultivated Proteus strains from urine of soldiers with spotted fever. As sera of such patients agglutinated these bacteria in considerable titers the investigators developed the reliable diagnostic "Weil-Felix-Test" used still today. In the same military area and time Rudolf Weigl invented the anal infection of lice. This enabled him to harvest a great amount of louse intestines containing the spotted fever Rickettsiae in their epithelial cells. Lots with defined numbers of intestines were homogenized, sterilized and used with success as vaccine for medical staff. This sort of vaccine still was used in World War II.

    Poor quality housing is an infringement on the rights of all humans to a standard of living adequate for health. Among the many vulnerabilities of those without adequate shelter is the risk of disease spread by rodents and other pests. One such disease is Lassa fever, an acute and sometimes severe viral hemorrhagic illness endemic in West Africa. Lassa virus is maintained in the rodent Mastomys natalensis, commonly known as the "multimammate rat," which frequently invades the domestic environment, putting humans at risk of Lassa fever. The highest reported incidence of Lassa fever in the world is consistently in the Kenema District of Sierra Leone, a region that was at the center of Sierra Leone's civil war in which tens of thousands of lives were lost and hundreds of thousands of dwellings destroyed. Despite the end of the war in 2002, most of Kenema's population still lives in inadequate housing that puts them at risk of rodent invasion and Lassa fever. Furthermore, despite years of health education and village hygiene campaigns, the incidence of Lassa fever in Kenema District appears to be increasing. We focus on Lassa fever as a matter of human rights, proposing a strategy to improve housing quality, and discuss how housing equity has the potential to improve health equity and ultimately economic productivity in Sierra Leone. The manuscript is designed to spur discussion and action towards provision of housing and prevention of disease in one of the world's most vulnerable populations.

    Introduction: Dengue fever is a global pandemic threat with increasing incidence. To date, there are no cures and the effectiveness of dengue vaccines is still uncertain. World Heath Organization introduced expanded dengue syndrome to include unusual presentations of dengue fever including severe neurologic complications. One of the deadly complications is intracranial hemorrhage (ICH). Methodology: We collected data of patients with ICH diagnosed via a plain computed tomography of the brain (CT brain) with thrombocytopenia and positive Dengue virus type 1 nonstructural protein (NS1) antigen test or positive dengue serology IgM from January 2014 till June 2015 at our center. Nine patients were included and all 20 other remaining patients reported in literature so far are discussed. Discussion: We found that all patients in our center requiring neurosurgical intervention died. Another interesting observation is that detection of Dengue IgG usually meant more severe ICH and poorer outcomes. From our series, platelet levels did not seem to influence the outcome. Conclusion: We recommend that for early detection of ICH, Dengue IgG should be routinely screened and a high index of suspicion be maintained. Future research should be focused on determining predictors of ICH in patients with dengue fever so that preventive steps can be taken as mortality is high and no treatment seems beneficial at the moment once severe ICH occurs.

    The article is concerned to the materials about epidemiologic situation of typhus fever in the regions around Volga river (Saratovsky, Samarsky and others) during World War I (1914-1918) among the military personnel of the Russian army and among the civilians. The main reasons for spread of infection, ways of the transmission, and also measures for decreasing of level of morbidity on the different stages of evacuation of patients with typhus fever in the safer hospitals are shown. The most important methods of fighting against epidemic of typhus fever were: isolation of patients in separate special hospitals, desincection and disinfection measures in the foci of infection and organization appropriate sanitary conditions for military man in the army and among civilians. Acquired valuable experience of territorial and military doctors during the period of epidemic of typhus fever allowed receiving complex effective antiepidemic measures of fighting and prevention from this disease.

    Trench fever became a major worry for the Allied High Command during the First World War because of its debilitating effects on troop performance. The causes of the fever were not previously known, but entomological research identified the body louse (pediculus humanus corporis) as the carrier, and the Royal Army Medical Corps developed effective methods of control through disinfestation. These were markedly influenced by the researches of a young entomologist, Alexander David Peacock, which were conducted under campaign conditions. Peacock subsequently occupied a Chair of Zoology at St. Andrews University for 30 years.

  9. The Multifactorial Epidemiology of Blackwater Fever.

    PubMed

    Shanks, G Dennis

    2017-12-01

    Blackwater fever is a massive hemolytic event usually occurring in the context of repeated falciparum malaria infections and intermittent quinine use. Its etiology is poorly understood, and it is rarely seen today. Historical epidemiological observations from the 20th century demonstrated variable patterns in prisoners in Andaman Islands, refugees in Macedonia, canal workers in Panama, expatriates in Rhodesia, and Second World War soldiers. Rates of blackwater fever per 1,000 malaria cases varied over two orders of magnitude. Islands, such as the Andaman Islands and New Guinea, had lower blackwater fever rates than continental areas. During the Second World War, blackwater fever rates in British soldiers in West Africa and Australian soldiers in New Guinea differed by a factor of 40 despite similar treatment regimens and falciparum malaria transmission risks. Blackwater fever is a complex interaction between host erythrocyte, falciparum malaria, and antimalarial drugs which remains poorly understood.

    2000-01-01

    At the end of history's bloodiest century and the outset of a new millennium, we have an opportunity to fulfil one of humanity's oldest dreams: making the world largely free of war. Global changes make this goal achievable. Nuclear weapons have shown the folly of war. For the first time, there is no war and no immediate prospect of war among the main military powers. For the first time, many proven measures to prevent armed conflict, distilled in the crucible of this century's wars, are available. If systematically applied, these measures can sharply decrease the frequency and violence of war, genocide, and other forms of deadly conflict. To seize the opportunity, nations should adopt a comprehensive programme to reduce conventional armaments and armed conflict. This programme will complement and strengthen efforts to eliminate nuclear arms. To assure its ongoing worldwide implementation, the conventional reduction programme should be placed in a treaty framework. We propose a four-phased process, with three treaties, each lasting five to ten years, to lay the groundwork for the fourth treaty, which will establish a permanent international security system. The main objectives of the treaties are to achieve: 1. A verified commitment to provide full transparency on conventional armed forces and military spending, not to increase forces during negotiations on arms reductions, and to increase the resources allocated to multilateral conflict prevention and peacekeeping. 2. Substantial worldwide cuts in national armed forces and military spending and further strengthening of United Nations and regional peacekeeping and peace-enforcement capabilities. 3. A trial of a watershed commitment by participating nations, including the major powers, not to deploy their armed forces beyond national borders except in a multilateral action under UN or regional auspices. 4. A permanent transfer to the UN and regional security organizations of the authority and capability for armed

  15. Lassa fever: the challenges of curtailing a deadly disease.

    2012-01-01

    Today Lassa fever is mainly a disease of the developing world, however several imported cases have been reported in different parts of the world and there are growing concerns of the potentials of Lassa fever Virus as a biological weapon. Yet no tangible solution to this problem has been developed nearly half a decade after its identification. Hence, the paper is aimed at appraising the problems associated with LAF illness; the challenges in curbing the epidemic and recommendations on important focal points. A Review based on the documents from the EFAS conference 2011 and literature search on PubMed, Scopus and Science direct. The retrieval of relevant papers was via the University of British Columbia and University of Toronto Libraries. The two major search engines returned 61 and 920 articles respectively. Out of these, the final 26 articles that met the criteria were selected. Relevant information on epidemiology, burden of management and control were obtained. Prompt and effective containment of the Lassa fever disease in Lassa village four decades ago could have saved the West African sub-region and indeed the entire globe from the devastating effect and threats posed by this illness. That was a hard lesson calling for much more proactive measures towards the eradication of the illness at primary, secondary and tertiary levels of health care.

  16. Dead sea asphalts: historical aspects

    Asphalts are present in the Dead Sea basin in three forms: (1) huge blocks, up to 100 tons in weight, composed of extremely pure (>99.99%) solid asphalt occasionally found floating on the lake, (2) veins, seepages, and cavity and fissure fillings in Lower Cretaceous to Holocene rocks, and (3) ozocerite veins on the eastern shore of the lake. Dead Sea asphalts probably have been documented over a longer period of time than any other hydrocarbon deposit--from antiquity to the 19th century. Major uses of asphalt from the Dead Sea have been as an ingredient in the embalming process, for medicinalmore » purposes, for fumigation, and for agriculture. The first known war for control of a hydrocarbon deposit was in the Dead Sea area in 312 B.C. between the Seleucid Syrians and the Nabatean Arabs who lived around the lake. Surface manifestations of asphalt are linked closely to tectonic activity. In the lake itself, the asphalt is associated with diapirs During certain historic periods, tectonic and diapiric activity caused frequent liberation to the Dead Sea surface of semiliquid asphalt associated with large amounts of hydrogen sulfide gas. When the tectonic activity was attenuated, as in the 19th and 20th centuries, the rate of asphalt seepage to the bottom sediments of the Dead Sea was much slower and the asphalt solidified on the lake bottom. The release of asphalt to the surface became much more sporadic, and may have resulted in part from earthquakes. Thus, future asphalt prospecting in the Dead Sea area should be conducted along the boundaries of diapirs or their associated faults.« less

    The behaviour of free ranging wild boar (Sus scrofa) towards carcasses of their conspecifics potentially infected with African swine fever (ASF) may significantly influence the course of an ASF epidemic. This study aims to better understand the behaviour of wild boar towards their dead fellows. Thirty-two wild boar carcasses on nine study sites in northeast Germany were monitored under field conditions by photo-trapping from October 2015 until October 2016. During this period, a total of 122 160 pictures were taken, thereof 16 111 pictures of wild boar. In both winter and summer, wild boar seemed to be particularly interested in the soil next to and underneath the carcasses. About one third of the visits of wild boar led to direct contact with dead conspecifics. The contacts consisted mostly in sniffing and poking on the carcass. Under the given ecological and climatic conditions, there was no evidence for intra-species scavenging. However, piglets were observed several times chewing bare bones once skeletonization of the carcasses was complete. It must be assumed that all these types of contact may represent a risk of transmission. Both the high tenacity of ASF virus and the long time wild boar carcasses can remain in the environment, allow the persistence of the virus for several months or even years. We therefore consider the rapid detection and removal (or destruction on the spot) of contaminated carcasses as an important control measure against ASF in wild boar. PMID:28573011

    There are currently no widely accepted animal surveillance guidelines for human Ebola hemorrhagic fever (EHF) outbreak investigations to identify potential sources of Ebolavirus (EBOV) spillover into humans and other animals. Animal field surveillance during and following an outbreak has several purposes, from helping identify the specific animal source of a human case to guiding control activities by describing the spatial and temporal distribution of wild circulating EBOV, informing public health efforts, and contributing to broader EHF research questions. Since 1976, researchers have sampled over 10,000 individual vertebrates from areas associated with human EHF outbreaks and tested for EBOV or antibodies. Using field surveillance data associated with EHF outbreaks, this review provides guidance on animal sampling for resource-limited outbreak situations, target species, and in some cases which diagnostics should be prioritized to rapidly assess the presence of EBOV in animal reservoirs. In brief, EBOV detection was 32.7% (18/55) for carcasses (animals found dead) and 0.2% (13/5309) for live captured animals. Our review indicates that for the purposes of identifying potential sources of transmission from animals to humans and isolating suspected virus in an animal in outbreak situations, (1) surveillance of free-ranging non-human primate mortality and morbidity should be a priority, (2) any wildlife morbidity or mortality events should be investigated and may hold the most promise for locating virus or viral genome sequences, (3) surveillance of some bat species is worthwhile to isolate and detect evidence of exposure, and (4) morbidity, mortality, and serology studies of domestic animals should prioritize dogs and pigs and include testing for virus and previous exposure.

    Dead of Night, the first psychoanalytic horror film, was produced in England in 1945, immediately after the end of World War II--that is, after the English population had suffered systematic Nazi terror from imminent invasion, incessant aerial bombing, and rocket-bombs. This film continued the prewar format of horror films based on themes of the supernatural and the hubris and excesses of science. However, it introduced psychoanalysis as the science in question. The film is structured on two levels: a genteel English country weekend to which witty and urbane guests have been invited; and five horror stories told by the guests. Psychoanalytic insights into this film structure are used here to explain how the film induces horror in the audience.

    During 1911-1914, using the resources of the Metropolitan Life Insurance Company, Louis I. Dublin conducted two national studies into the survival of those surviving episodes of typhoid fever or scarlet fever. He identified an elevated risk of such mortality, associated with specific causes of death, among those having had typhoid fever but not among the scarlet fever survivors. The studies were methodologically sophisticated, resembling those conducted three to four decades later. The studies appear to have been accepted by the medical and public health communities. However, the absence of modern data processing technology and the lack of financial support for such studies by other investigators precluded the further development of modern epidemiology until World War II.

    During World War II, nearly all US and Allied troops received yellow fever vaccine. Until May 1942, it was both grown and suspended in human serum. In April 1942, major epidemics of hepatitis occurred in US and Allied troops who had received yellow fever vaccine. A rapid and thorough investigation by the US surgeon general followed, and a directive was issued discontinuing the use of human serum in vaccine production. The large number of cases of hepatitis caused by the administration of this vaccine could have been avoided. Had authorities undertaken a thorough review of the literature, they would have discovered published reports, as early as 1885, of postvaccination epidemics of hepatitis in both men and horses. It would take 4 additional decades of experiments and epidemiological research before viruses of hepatitis A, B, C, D, and E were identified, their modes of transmission understood, and their genomes sequenced.

    Armed conflict within nations has had disastrous humanitarian consequences throughout much of the world. Here we undertake the first comprehensive examination of the potential impact of global climate change on armed conflict in sub-Saharan Africa. We find strong historical linkages between civil war and temperature in Africa, with warmer years leading to significant increases in the likelihood of war. When combined with climate model projections of future temperature trends, this historical response to temperature suggests a roughly 54% increase in armed conflict incidence by 2030, or an additional 393,000 battle deaths if future wars are as deadly as recent wars. Our results suggest an urgent need to reform African governments' and foreign aid donors' policies to deal with rising temperatures.

    Russell, W M S

    2002-01-01

    This article discusses three serious wars that were averted and the three men who averted them. In 1478-79, Pope Sixtus IV's hatred of the Medici culminated in aggressive war against Florence, supported by his powerful ally King Ferrante of Naples. The initial stags of this war were indecisive, but it was about to become much more serious, probably involving all the Italian states and possibly meaning the total destruction of Florence. Lorenzo il Magnifico sailed to Naples, convinced Ferrante this more serious war was against his interests and obtained a generous peace. In 1861, the British Government responded to the boarding of a British ship by a vessel of the American North with a peremptory letter. Albert, Prince Consort, though dying of typhoid fever amended the letter to save Lincoln's face and thus averted war with the North. From 1871 to 1890, Otto von Bismarck worked for a stable peace between the European powers to be attained by arranging meetings of most or all of them to accustom them to solving disputes by negotiation. Two such meetings in Berlin secured 36 years of peace between the powers, despite many disputes, and in particular averted war for possessions in Africa, which could have involved them all.

    This introduction proceeds in five steps. First, it briefly considers the etymology of the term "suffering," as well as the way in which scholars from different disciplines have approached it conceptually and empirically. Second, drawing on the contributions to this issue, it raises general themes emerging from the study of the Thirty Years, Franco-Prussian and First World Wars, with particular attention to gender, the disabled, and Jewish-German veterans. Finally, it considers the most politically contested field of German suffering - the Second World War - and reflects on how that suffering can be narrated and understood without running into the intellectual dead ends of either self-pity or collective guilt.

    Crimean Congo hemorrhagic fever (CCHF) is one of the deadly hemorrhagic fevers that are endemic in Africa, Asia, Eastern Europe, and the Middle East. It is a tick-borne zoonotic viral disease caused by CCHF virus of genus Nairovirus (family Bunyaviridae). CCHF not only forms an important public health threat but has a significant effect on the healthcare personnel, especially in resource-poor countries. India was always a potentially endemic area until an outbreak hit parts of Gujarat, taking four lives including the treating medical team. The current review is an attempt to summarize the updated knowledge on the disease particularly in modern era, with special emphasis on nosocomial infections. The knowledge about the disease may help answer certain questions regarding entry of virus in India and future threat to community. PMID:21887063

    In Lvov and Cracow at the times of World War I, the infectious diseases such as tuberculosis followed by typhus fever, typhoid fever, dysentery, as well as scarlet fever, diphtheria, measles, whooping cough, smallpox, cholera and venereal diseases (particularly syphilis) posed one of the most significant and dangerous problems for inhabitants. Their increased prevalence was the result of deteriorating sanitary and living conditions of the city population. The spread of epidemic infectious diseases was enhanced by marching troops, migration of civilians and war prisoners, return of large groups of displaced people and demobilized soldiers after regaining independence in November 1918. Additionally, unfavorable epidemiological situation in Lvov deteriorated at the time of the war with Ukrainians (November 1918-April 1919) and Bolsheviks (July-August 1920). The control of infectious diseases was in the hands of regional local physicians who referred patients to hospitals, isolated homes, bath and disinfection institutions, and conducted vaccinations against smallpox. A decrease in infectious diseases prevalence and deaths to the prewar levels occurred in 1922.

  12. [Complications and cause of death in mexican children with rocky mountain spotted fever].

    PubMed

    Martínez-Medina, Miguel Ángel; Rascón-Alcantar, Adela

    Rocky Mountain spotted fever is a life threatening disease caused by Rickettsia rickettsia, characterized by multisystem involvement. We studied 19 dead children with Rocky Mountain spotted fever. All children who were suspected of having rickettsial infections were defined as having Rocky Mountain spotted fever by serology test and clinical features. Through the analysis of each case, we identified the clinical profile and complications associated to the death of a patient. In nine (69.2%) of 13 cases that died in the first three days of admission, the associated condition was septic shock. Others complications included respiratory distress causes by non-cardiogenic pulmonary edema, renal impairment, and multiple organ damage. The main cause of death in this study was septic shock. The fatality rate from Rocky Mountain spotted fever can be related to the severity of the infection, delay in diagnosis, and delay in initiation of antibiotic therapy. Pulmonary edema and cerebral edema can be usually precipitated by administration of excess intravenous fluids.

    During August 2007-February 2008, the novel Bundibugyo ebolavirus species was identified during an outbreak of Ebola viral hemorrhagic fever in Bundibugyo district, western Uganda. To characterize the outbreak as a requisite for determining response, we instituted a case-series investigation. We identified 192 suspected cases, of which 42 (22%) were laboratory positive for the novel species; 74 (38%) were probable, and 77 (40%) were negative. Laboratory confirmation lagged behind outbreak verification by 3 months. Bundibugyo ebolavirus was less fatal (case-fatality rate 34%) than Ebola viruses that had caused previous outbreaks in the region, and most transmission was associated with handling of dead persons without appropriate protection (adjusted odds ratio 3.83, 95% confidence interval 1.78-8.23). Our study highlights the need for maintaining a high index of suspicion for viral hemorrhagic fevers among healthcare workers, building local capacity for laboratory confirmation of viral hemorrhagic fevers, and institutionalizing standard precautions.

    Yellow fever (YF) is a viral hemorrhagic fever endemic to tropical regions of South America and Africa. From 2007 to 2009 an important epidemic/epizootic of YF was detected in different populations of howler monkeys (Alouatta species) in Misiones, a northeastern Argentinian province. Yellow fever virus (YFV) infection was researched and documented by laboratory tests in humans and in dead Alouatta carayá. The objective of that research was to investigate the circulation of YFV in mosquitoes, which could be implicated in the sylvatic transmission of YF in Argentina. The above-mentioned mosquitoes were captured in the same geographical region where the epizootic took place. A YFV strain was isolated in cell culture from pools of Sabethes albiprivus. This study is not only the first isolation of YFV from mosquitoes in Argentina, but it is also the first YFV isolation reported in the species Sabethes albiprivus, suggesting that this species might be playing a key role in sylvatic YF in Argentina.

    Arenaviruses are enveloped single-strand RNA viruses that mostly have natural hosts in rodents. Upon infection of humans, several arenaviruses can cause severe hemorrhagic fever diseases, including Lassa fever that is endemic in West Africa. The virulence mechanism of these deadly arenaviruses can be studied in a safe and economical small animal model-guinea pigs infected by a nonpathogenic arenavirus Pichinde virus (PICV), a virulent strain of which can cause similar disease syndromes in guinea pigs as arenaviral hemorrhagic fevers in humans. We have recently developed molecular clones for both the virulent and avirulent strains of PICV. Using the available reverse genetics tools, we are characterizing the molecular determinants of virulent arenavirus infections in vivo.

    Coxiella burnetii is an intracellular bacterial pathogen that causes Q fever. Infected pregnant goats are a major source of human infection. However, the tissue dissemination and excretion pathway of the pathogen in goats are still poorly understood. To better understand Q fever pathogenesis, we inoculated groups of pregnant goats via the intranasal route with a recent Dutch outbreak C. burnetii isolate. Tissue dissemination and excretion of the pathogen were followed for up to 95 days after parturition. Goats were successfully infected via the intranasal route. PCR and immunohistochemistry showed strong tropism of C. burnetii towards the placenta at two to four weeks after inoculation. Bacterial replication seemed to occur predominantly in the trophoblasts of the placenta and not in other organs of goats and kids. The amount of C. burnetii DNA in the organs of goats and kids increased towards parturition. After parturition it decreased to undetectable levels: after 81 days post-parturition in goats and after 28 days post-parturition in kids. Infected goats gave birth to live or dead kids. High numbers of C. burnetii were excreted during abortion, but also during parturition of liveborn kids. C. burnetii was not detected in faeces or vaginal mucus before parturition. Our results are the first to demonstrate that pregnant goats can be infected via the intranasal route. C. burnetii has a strong tropism for the trophoblasts of the placenta and is not excreted before parturition; pathogen excretion occurs during birth of dead as well as healthy animals. Besides abortions, normal deliveries in C. burnetii-infected goats should be considered as a major zoonotic risk for Q fever in humans. PMID:23152826

    2018-04-01

    Dengue fever is an acute febrile illness with a duration of 2-12 days. Our observational study observed the 24-h continuous tympanic temperature pattern of 15 patients with dengue fever and compared this with 26 others with fever due to a non-dengue aetiology. A tri-phasic fever pattern was seen among two-thirds of dengue fever patients, but in only one with an inflammatory disease. One-third of dengue fever patients exhibited a single peak temperature. Continuous temperature monitoring and temperature pattern analysis in clinical settings can aid in the early differentiation of dengue fever from non-dengue aetiology.

    Acute infectious diseases of high intensity, i.e. typhus fever, typhoid fever, dysentery, followed by scarlet fever, measles, malaria, relapsing fever, whooping cough, diphtheria, smallpox and Asiatic cholera spreading after the World War I in Poland posed one of the most significant problems in the reviving country. Their incidence resulted not only from bad living conditions of the population but also from poor personal and environmental hygiene and lack of access to bacteriologically healthy drinking water. The Polish-Bolshevik war (1919-1920) as well as repatriation of war prisoners and the Polish population from Russia (its territory was a reservoir of numerous infectious diseases) and the return of large groups of displaced people contributed to spread of epidemics. Morbidity rate of acute infectious diseases was the highest in the big Polish cities, especially in Warsaw, Lodz, Lvov, Cracow and Vilnius. The Bureau of Chief Emergency Commissar for fighting against epidemics, which closely cooperated with other Polish sanitary institutions and international organisations, rendered the greatest service to the control of infectious diseases. Until the year 1924, the largest foci of diseases were controlled and their incidence decreased, what was possible after formation of sanitary posts along the eastern border of Poland, organisation of infectious disease hospitals, bath and disinfection centres in the country, and implementation of protective vaccinations.

    PubMed

    Jalland, Pat

    2014-06-01

    The First World War was a turning point in the cultural history of death and bereavement in Australia. The mass deaths of some 60,000 soldiers overseas led to communal rituals of mourning for the war dead and minimal public expressions of private grief. The mass slaughter of so many young men and the interminable grief of so many families devalued the deaths of civilians at home and helped to create a new cultural model of suppressed and privatised grieving which deeply constrained the next two generations. Emotional and expressive grieving became less common, mourning ritual was minimised and sorrow became a private matter. Copyright © 2014. Published by Elsevier Ltd.

    Ebola virus, described in 1976 in Zaire, causes severe hemorrhagic fever with a high mortality rate in humans and nonhuman primates. Epidemics occurred since this time to nowadays in Sudan, Gabon, Congo and currently in Guinea, Liberia, Sierra-Leone, Nigeria and Senegal. Specific treatment and vaccine are not available. So, to prevent the virus transmission with live and dead patients, we must use strict individual and collective measures which are not always understood by local populations and make contact tracing; it is the only way to curb the epidemic.

    During the period 2007-2008 several epizootics of Yellow fever with dead of monkeys occurred in southeastern Brasil, Paraguay, and northeastern Argentina. In 2008 after a Yellow fever outbreak an exhaustive prevention campaign took place in Argentina using 17D live attenuated Yellow fever vaccine. This vaccine is considered one of the safest live virus vaccines, although serious adverse reactions may occur after vaccination, and vaccine-associated neurotropic disease are reported rarely. The aim of this study was to confirm two serious adverse events associated to Yellow fever vaccine in Argentina, and to describe the analysis performed to assess the origin of specific IgM against Yellow fever virus (YFV) in cerebrospinal fluid (CSF). Both cases coincided with the Yellow fever vaccine-associated neurotropic disease case definition, being clinical diagnosis longitudinal myelitis (case 1) and meningoencephalitis (case 2). Specific YFV antibodies were detected in CSF and serum samples in both cases by IgM antibody-capture ELISA. No other cause of neurological disease was identified. In order to obtain a conclusive diagnosis of central nervous system (CNS) infection the IgM antibody index (AI(IgM) ) was calculated. High AI(IgM) values were found in both cases indicating intrathecal production of antibodies and, therefore, CNS post-vaccinal YFV infection could be definitively associated to YFV vaccination.

    Hemorrhagic fever with renal syndrome (HFRS) has been known from ancient times as a disease with many names, which raised great interest during the Korean war (1951-1954), occurring as a large epidemic (Korean hemorrhagic fever). Therefore, the subsequently discovered causative agent was named after the Hantaan River which runs along the 38th parallel and divides North Korea from South Korea. A similar disease was described in 1934 in Scandinavian countries (epidemic nephrosonephritis or nephropathy). During the Second World War, the disease was also registered as wartime nephritis in several European south-eastern countries. Since 1982, similar clinical manifestations of the disease, differently named in various parts of the world, have been assigned one unique name--hemorrhagic fever with renal syndrome, as recommended by the World Health Organization. In Croatia, the first patient with HFRS was diagnosed in 1952 and the paper describing the case was published in 1954 (Radosevic and Mohacek). Since then, the disease has been regularly occurring in our country, especially in sporadic form, with only two smaller epidemics recorded until 1995. The first epidemic with 14 forestry workers involved occurred in 1967 at the Plitvice Lakes, and the second with the same number of soldiers in 1989 around the Pieso-Airport near Zagreb. Simultaneously, in 1967 and 1989 two large-scale epidemics of HFRS occurred in Bosnia and Herzegovina with 144 cases each. Until the first large epidemic of HFRS in Croatia during the Croatian War in 1995, occurring at several localities (Mala Kapela, Dinara mountain, west Slavonia), it was considered that there were only several natural foci of the disease in Croatia (around Ogulin and Slunj, Plitvice Lakes, Zagreb surroundings). A total of 125 cases were reported to the Croatian National Institute of Public Health in 1995. Fifty patients, 45 of them soldiers, were hospitalized at Dr. Fran Mihaljević University Hospital for infectious

    The First World War (1914-1918) was the first truly industrial conflict in human history. Never before had rifle fire and artillery barrage been employed on a global scale. It was a conflict that over 4 years would leave over 750,000 British troops dead with a further 1.6 million injured, the majority with orthopaedic injuries. Against this backdrop, the skills of the orthopaedic surgeon were brought to the fore. Many of those techniques and systems form the foundation of modern orthopaedic trauma management. On the centenary of 'the War to end all Wars', we review the significant advances in wound management, fracture treatment, nerve injury and rehabilitation that were developed during that conflict.

    2018-07-01

    Rocky Mountain spotted fever (RMSF) is potentially deadly and can present subtly with signs and symptoms overlapping with other clinical conditions. Delayed diagnosis can be fatal. This review provides an evidence-based summary of the current data for the evaluation and management of RMSF in the emergency department. RMSF occurs through transmission of Rickettsia rickettsii by an infected tick. Exposure in the United States occurs most commonly from April to September, and high-risk locations include wooded, shrubby, or grassy areas. Approximately half of patients with infection do not recall tick exposure. Symptoms can include fever, headache, photophobia, malaise, myalgias, and a petechial rash that begins on the wrists and ankles and spreads to the trunk. Rash may not occur in ≤15% of patients, and the classic triad of fever, headache, and rash is also not definitive. Laboratory evaluation may demonstrate hyponatremia, anemia, thrombocytopenia, abnormal liver enzymes, and elevated coagulation tests. Antibody testing can be helpful, but these results are not typically available to the emergency clinician. Doxycycline is the treatment of choice in adults, children, and pregnant patients. Patients should be advised about prevention strategies and effective techniques for removing ticks. RMSF is a potentially deadly disease that requires prompt recognition and management. Focused history, physical examination, and testing are important in the diagnosis of this disease. Understanding the clinical features, diagnostic tools, and proper treatment can assist emergency clinicians in the management of RMSF. Published by Elsevier Inc.

    Inhalational exposure to metal-containing fumes generated by welding and related processes may result in the development of the clinical syndrome known as "metal fume fever." Polymer fume fever is a separate and distinct but related disorder that has been associated with inhalational exposure to specific fluorinated polymer products, such as polytetrafluoroethylene or Teflon(®). We undertook a review of the peer-reviewed medical literature as it relates to these two disease entities in order to describe their epidemiology, pathophysiology, clinical presentation, diagnosis, treatment, prevention, and prognosis. We performed a search of the PubMed ( www.pubmed.com ) and Ovid MEDLINE (ovidsp.tx.ovid.com) databases for keywords "metal fume fever," "polymer fume fever," and "fume fever," covering the period 1946 to September 2014, which resulted in a total of 141 citations. Limiting the search to articles published in the English language yielded 115 citations. These 115 articles were manually reviewed for relevance. In addition, the reference lists in each article retrieved were reviewed for additional relevant references. This left 48 relevant citations. Metal fume fever occurs most commonly as an occupational disease in individuals who perform welding and other metal-joining activities for a living. It is estimated that 1,500-2,500 cases of metal fume fever occur annually in the United States. Polymer fume fever was initially identified as an occupational disease but increased regulations have resulted in decreased incidence in the occupational setting. Overheating of Teflon(®)-coated cookware is one of the more common mechanisms for exposure. While the precise pathophysiology associated with the development of metal fume fever is yet to be elucidated, suggested pathophysiologic mechanisms include pro-inflammatory cytokine release, neutrophil activation, and oxygen radical formation. The pathophysiologic mechanism for polymer fume fever has not been definitively

    The death of a military service member in war provokes feelings of distress and pride in mortuary workers who process the remains. To further understand their reactions, the authors interviewed 34 military and civilian personnel to learn more about their work stresses and rewards. They review stresses of anticipation, exposure, and experience in handling the dead and explore the personal, supervisory, and leadership strategies to reduce negative effects and promote personal growth. These results can be applied to many other situations requiring planning, implementing, and supervising mortuary operations involving mass death.

    Measurement of body temperature remains one of the most common ways to assess health. An increase in temperature above what is considered to be a normal value is inevitably regarded as a sure sign of disease and referred to with one simple word: fever. In this review, we summarize how research on fever allowed the identification of the exogenous and endogenous molecules and pathways mediating the fever response. We also show how temperature elevation is common to different pathologies and how the molecular components of the fever-generation pathway represent drug targets for antipyretics, such as acetylsalicylic acid, the first “blockbuster drug”. We also show how fever research provided new insights into temperature and energy homeostasis, and into treatment of infection and inflammation. PMID:20305990

    This paper proposes a dead-time compensation structure for processes with multiple dead times. The controller is based on the filtered Smith predictor (FSP) dead-time compensator structure and it is able to control stable, integrating, and unstable processes with multiple input/output dead times. An equivalent model of the process is first computed in order to define the predictor structure. Using this equivalent model, the primary controller and the predictor filter are tuned to obtain an internally stable closed-loop system which also attempts some closed-loop specifications in terms of set-point tracking, disturbance rejection, and robustness. Some simulation case studies are used to illustrate the good properties of the proposed approach. Copyright © 2014 ISA. Published by Elsevier Ltd. All rights reserved.

  18. Raising the Dead without a Red Sea-Dead Sea Canal? A hydro-economic-institutional analysis

    NASA Astrophysics Data System (ADS)

    Rosenberg, D. E.

    2010-12-01

    Presently, just 100 million cubic meters per year (MCM/year) of the 1,000+ MCM/year that historically flowed in the lower Jordan River reach the Dead Sea. Israeli, Jordanian, and Syrian dam and extraction projects built over seven decades have principally caused the reduced flow, associated falling Dead Sea level, shrinking surface area, sink holes, salinity, and other catastrophic problems. These problems will be magnified in the face of up to 20% reductions in precipitation expected with climate change. The fix proposed by Jordan, Israel, and Palestine—and now under study by the World Bank—envisions building a $US 5 billion multipurpose canal from the Red Sea to the Dead Sea that would also generate hydropower and desalinated water. Yet alternatives to raise the Dead Sea level that could take advantage of hydrologic variability remain unstudied. Here we show system-wide hydrologic and economic impacts of and discusses institutional management for alternatives to raise the Dead Sea level. Hydro-economic model results for the inter-tied Israel-Jordan-Palestinian water systems show the desalination component of the Red Sea-Dead Sea project is economically unviable. Further, many decentralized new supply, wastewater reuse, conveyance, conservation, and leak reduction projects and programs in each country together increase economic benefits and can reliably deliver up to 900 MCM/year to the Dead Sea. In all cases, results show that net benefits fall and water scarcity rises as the flow volume delivered to the Dead Sea increases. These findings suggest that (i) each country has little individual incentive to allow water to flow to the Dead Sea, and (ii) outside institutions—such as the World Bank—that seek to raise the Dead should instead offer the countries direct incentives to deliver water rather than build them new infrastructure. The work expands the set of viable options to raise the Dead Sea level and can help the World Bank and others recommend whether

    Patients in persistent vegetative state (PVS) may be biologically alive, but these experiments indicate that people see PVS as a state curiously more dead than dead. Experiment 1 found that PVS patients were perceived to have less mental capacity than the dead. Experiment 2 explained this effect as an outgrowth of afterlife beliefs, and the tendency to focus on the bodies of PVS patients at the expense of their minds. Experiment 3 found that PVS is also perceived as "worse" than death: people deem early death better than being in PVS. These studies suggest that people perceive the minds of PVS patients as less valuable than those of the dead - ironically, this effect is especially robust for those high in religiosity.

    2017-02-01

    Fever is a relatively common occurrence among patients in the intensive care setting. Although the most obvious and concerning etiology is sepsis, drug reactions, venous thromboembolism, and postsurgical fevers are all on the differential diagnosis. There is abundant evidence that fever is detrimental in acute neurologic injury. Worse outcomes are reported in acute stroke, subarachnoid hemorrhage, and traumatic brain injury. In addition to the various etiologies of fever in the intensive care setting, neurologic illness is a risk factor for neurogenic fevers. This primarily occurs in subarachnoid hemorrhage and traumatic brain injury, with hypothalamic injury being the proposed mechanism. Paroxysmal sympathetic hyperactivity is another source of hyperthermia commonly seen in the population with traumatic brain injury. This review focuses on the detrimental effects of fever on the neurologically injured as well as the risk factors and diagnosis of neurogenic fever.

    2012-01-01

    For thousands of years insects have been incorporated into human conflict, with the goals of inflicting pain, destroying food, and transmitting pathogens. Early methods used insects as "found" weapons, functioning as tactical arms (e.g., hurled nests) or in strategic habitats (e.g., mosquito-infested swamps). In the twentieth century the relationship between insects and disease was exploited; vectors were mass-produced to efficiently deliver pathogens to an enemy. The two most sophisticated programs were those of the Japanese in World War II with plague-infected fleas and cholera-coated flies and of the Americans during the Cold War with yellow fever-infected mosquitoes. With continued advances, defenses in the form of insecticides and vaccines meant that insects were no longer considered as battlefield weapons. However, in recent times sociopolitical changes have put insects back into the realm of human conflict through asymmetrical conflicts pitting combatants from nonindustrialized regions against forces from militarily and economically superior nations.

  6. Analysis of México’s Narco-War Network (2007–2011)

    2015-01-01

    Since December 2006, more than a thousand cities in México have suffered the effects of the war between several drug cartels, amongst themselves, as well as with Mexican armed forces. Sources are not in agreement about the number of casualties of this war, with reports varying from 30 to 100 thousand dead; the economic and social ravages are impossible to quantify. In this work we analyze the official report of casualties in terms of the location and the date of occurrence of the homicides. We show how the violence, as reflected by the number of casualties, has increased over time and spread across the country. Next, based on the correlations between cities in the changes of the monthly number of casualties attributed to organized crime, we construct a narco-war network where nodes are the affected cities and links represent correlations between them. We find that close geographical distance between violent cities does not imply a strong correlation amongst them. We observe that the dynamics of the conflict has evolved in short-term periods where a small core of violent cities determines the main theatre of the war at each stage. This kind of analysis may also help to describe the emergence and propagation of gang-related violence waves. PMID:25993657

    Dengue Haemorrhagic Fever (DHF) is one of major health problems in Indonesia. DHF is a caused by the dengue virus and potentially deadly infection spread by some mosquitos. The mosquito Aedes aegypti is the main species that spreads this disease. The incidence rate of dengue haemorrhagic fever was still increased in 2011 to 2015 in Indonesia. Dengue viruses and their mosquito vectors are sensitive to their environment. Temperature, rainfall and humidity have well-define roles in the transmission cycle. Therefore changes in these conditions may contribute to increasing incidence. The aim of this study was to analyze the relationship between climate factors and the incidence rate of dengue hemorrhagic fever in Semarang City. The type of research was analytic with cross sectional study. The sample used is the climate data from Meteorology, Climatology and Geophysics Agency (BMKG) and the number of dengue cases from Health Office in Semarang City from 2011 to 2016. Data were analyzed using Pearson trials with α=0,05. Base on this study here air temperature and relative humidity were moderate correlation with negative direction on air temperature (p = 0,000 and r = -0, 429), weakly correlation with positive direction on rainfall (p = 0,014 and r = 0,288) and humidity (p=0,001 and r = 0,382) with dengue hemorrhagic fever incidence in Semarang City. The conclusions of this study there were correlation between climate (air temperature, rainfall, and relative humidity) and DHF in Semarang City in 2011-2016.

    One of the most important disadvantages of war environmental is infectious diseases. The Ottoman Empire combated infectious diseases in addition to the war because of Balkan wars and afterwards first world war. Because of increasing migrations to Anatolia after Balkan wars spread some epidemic diseases, such as cholera, typhoid fever, plaque, dysentery, syphilis. With the start of the First World War, malaria began to spread within civilian population as well as the military. The population fell from power because of illness and therefore could not process the land tax failed to pay taxes. Founded in 1914 with the fight against epidemic diseases was initiated by the Sıhhiye ministry. Quinine was formed as tablets which was imported from Germany by legal regulation and was distributed to the public by Ziraat Bank. However, malaria epidemic could not be prevented because of long war years, lack of population, insufficiency of the preventive methods and lack of quinine, and about three quarters of the population caught malaria and in four years 412.000 soldiers had malaria and 20.000 of them died despite of measures.

    2010-01-01

    Fever is an active yet nonspecific response of the body to infections and other insults that cause immune cells to release cytokines, resulting in a brain prostanoid-mediated rise in body temperature. The causes, types, clinical management, and postoperative consequences of fever are reviewed in this article. Physicians use fever as a clinical sign for diagnoses and prognoses, but "fevers of unknown origin" continue to be problematic. Fevers that arise 1 or 2 days after surgery are usually due to stress and trauma, but later postoperative fevers often have more serious causes and consequences, such as wound infection. Fever is commonly encountered by podiatric physicians and surgeons, and certain procedures with the lower extremity are more likely to eventuate in fever.

    2003-09-01

    Rat bite fever is a rarely reported acute febrile bacterial illness caused by Streptobacillus moniliformis or Spirillum minus following a rat bite. It is classically characterised by abrupt onset of fever with rigors, myalgias, headache, and the appearance of a generalised maculopapular petechial skin rash. Polyarthritis complicates the course of the disease in up to 50% of infected patients, and numerous hurdles can make the diagnosis particularly difficult in the absence of fever or rash, as in the present case. A high degree of awareness is necessary to make the correct diagnosis in such cases. Diagnosis has important prognostic implications as the disease is potentially lethal, but easily treatable.

    Fever is a common presenting complaint among adult or pediatric patients in the emergency department setting. Although fever in healthy individuals does not necessarily indicate severe illness, fever in patients with neutropenia may herald a life-threatening infection. Therefore, prompt recognition of patients with neutropenic fever is imperative. Serious bacterial illness is a significant cause of morbidity and mortality for neutropenic patients. Neutropenic fever should trigger the initiation of a rapid work-up and the administration of empiric systemic antibiotic therapy to attenuate or avoid the progression along the spectrum of sepsis, severe sepsis, septic shock syndrome, and death.

    2017-05-01

    Rift Valley Fever (RVF), is a viral zoonotic disease transmitted by Aedes and Culex mosquitoes. In Kenya, its occurrence is associated with increased rains. In Baringo County, RVF was first reported in 2006-2007 resulting in 85 human cases and 5 human deaths, besides livestock losses and livelihood disruptions. This study sought to investigate the county's current RVF risk status. A cross-sectional study on the knowledge, attitudes and practices of RVF was conducted through a mixed methods approach utilizing a questionnaire survey (n = 560) and 26 focus group discussions (n = 231). Results indicate that study participants had little knowledge of RVF causes, its signs and symptoms and transmission mechanisms to humans and livestock. However, most of them indicated that a person could be infected with zoonotic diseases through consumption of meat (79.2%) and milk (73.7%) or contact with blood (40%) from sick animals. There was a statistically significant relationship between being male and milking sick animals, consumption of milk from sick animals, consuming raw or cooked blood, slaughtering sick livestock or dead animals for consumption (all at p≤0.001), and handling sick livestock with bare hands (p = 0.025) with more men than women engaging in the risky practices. Only a few respondents relied on trained personnel or local experts to inspect meat for safety of consumption every time they slaughtered an animal at home. Sick livestock were treated using conventional and herbal medicines often without consulting veterinary officers. Communities in Baringo County engage in behaviour that may increase their risk to RVF infections during an outbreak. The authors recommend community education to improve their response during outbreaks.

  1. No Time for Dead Time: Use the Fourier Amplitude Differences to Normalize Dead-time-affected Periodograms

    NASA Astrophysics Data System (ADS)

    Bachetti, Matteo; Huppenkothen, Daniela

    2018-02-01

    Dead time affects many of the instruments used in X-ray astronomy, by producing a strong distortion in power density spectra. This can make it difficult to model the aperiodic variability of the source or look for quasi-periodic oscillations. Whereas in some instruments a simple a priori correction for dead-time-affected power spectra is possible, this is not the case for others such as NuSTAR, where the dead time is non-constant and long (∼2.5 ms). Bachetti et al. (2015) suggested the cospectrum obtained from light curves of independent detectors within the same instrument as a possible way out, but this solution has always only been a partial one: the measured rms was still affected by dead time because the width of the power distribution of the cospectrum was modulated by dead time in a frequency-dependent way. In this Letter, we suggest a new, powerful method to normalize dead-time-affected cospectra and power density spectra. Our approach uses the difference of the Fourier amplitudes from two independent detectors to characterize and filter out the effect of dead time. This method is crucially important for the accurate modeling of periodograms derived from instruments affected by dead time on board current missions like NuSTAR and Astrosat, but also future missions such as IXPE.

    After the discovery of the New World, yellow fever proved to be an important risk factor of morbidity and mortality for Caribbean populations. In the following centuries epidemic risk, expanded by sea trade and travel, progressively reached the settlements in North America and Brazil as well as the Atlantic seaboard of tropical and equatorial Africa. In the eighteenth century and the first half of the nineteenth century epidemics of yellow fever were reported in some coastal towns in the Iberian peninsula, French coast, Great Britain and Italy, where, in 1804 at Leghorn, only one epidemic was documented. Prevention and control programs against yellow fever, developed at the beginning of the twentieth century in Cuba and in Panama, were a major breakthrough in understanding definitively its aetiology and pathogenesis. Subsequently, further advances in knowledge of yellow fever epidemiology were obtained when French scientists, working in West and Central Africa, showed that monkeys were major hosts of the yellow fever virus (the wild yellow fever virus), besides man. In addition, advances in research, contributing to the development of vaccines against the yellow fever virus in the first half of the nineteenth century, are reported in this paper.

    In the early 20th century, when it was discovered that the yellow fever virus was transmitted in its urban cycle by Aedes aegypti, measures of control were introduced leading to its disappearance. Progressive neglect of the disease, however, led to a new outbreak in 1927 during which the etiological agent was isolated; some years later a vaccine was discovered and yellow fever disappeared again. In the 1960s, rare cases of encephalitis were observed in young children after vaccination and the administration of the vaccine was forbidden for children under 10 years. Five years later, a new outbreak of yellow fever in Diourbel, Senegal, was linked to the presence of Aedes aegypti. In the late 1970s, the idea of a selvatic cycle for yellow fever arose. Thanks to new investigative techniques in Senegal and Côte d'Ivoire, the yellow fever virus was isolated from the reservoir of virus and vectors. The isolated virus was identified in monkeys and several vectors: Aedes furcifer, Aedes taylori, Aedes luteocephalus. Most importantly, the virus was isolated in male mosquitoes. Until recently, the only known cycle had been that of Haddow in East Africa. The virus circulate in the canopea between monkeys and Aedes africanus. These monkeys infect Aedes bromeliae when they come to eat in banana plantations. This cycle does not occur in West Africa. Vertical transmission is the main method of maintenance of the virus through the dry season. "Reservoirs of virus" are often mentioned in medical literature, monkeys having a short viremia whereas mosquitoes remain infected throughout their life cycle. In such a selvatic cycle, circulation can reach very high levels and no child would be able to escape an infecting bite and yet no clinical cases of yellow fever have been reported. The virulence--as it affects man--of the yellow fever virus in its wild cycle is very low. In areas where the virus can circulate in epidemic form, two types of circulation can be distinguished

    For centuries pictures of the dead and wounded have been part and parcel of war communications. Often the intentions were clear, ranging from medical instructions to anti-war protests. The public's response could coincide with or diverge from the publisher's intention. Following the invention of photography in the nineteenth century, and the subsequent claim of realism, the veracity of medical war images became more complex. Analysing and understanding such photographs have become an ethical obligation with democratic implications. We performed a multidisciplinary analysis of War Surgery (2008), a book containing harsh, full-colour photographs of mutilated soldiers from the Iraq and Afghanistan wars. Our analysis shows that, within the medical context, this book is a major step forward in medical war communication and documentation. In the military context the book can be conceived as an attempt to put matters right given the enormous sacrifice some individuals have suffered. For the public, the relationship between the 'reality' and 'truth' of such photographs is ambiguous, because only looking at the photographs without reading the medical context is limiting. If the observer is not familiar with medical practice, it is difficult for him to fully assess, signify and acknowledge the value and relevance of this book. We therefore assert the importance of the role of professionals and those in the humanities in particular in educating the public and initiating debate.

    At the beginning of the First World War the most typical diseases in the Russian Army were typhoid, typhus, diphtheria, cholera, smallpox and other infectious diseases. At the beginning of the First World War the level of infectious morbidity was significantly low, but further increased and pandemic risk arose. Servicemen were mostly ill with typhus, relapsing fever, flux, cholera, smallpox and typhoid. The highest mortality rate was registered in patients with cholera, typhus and typhoid. According the prewar deployment program of the Russian Army anti-epidemiologic facilities were established. By the end of war were established 110 sanitary-and-hygienic and 90 disinfection units. However, organization of anti-epidemiologic security was unsatisfactory. Due to lack of specialists and equipment anti-epidemiologic facilities of units were under strength. Commanders of sanitary units and sanitary service had not enough resources for operational service in the Forces and facilities of rear area.

    In Poland, African swine fever (ASF) emerged in February 2014; by August 2015, the virus had been detected in >130 wild boar and in pigs in 3 backyard holdings. We evaluated ASF spread in Poland during these 18 months. Phylogenetic analysis indicated repeated incursions of genetically distinct ASF viruses of genotype II; the number of cases positively correlated wild boar density; and disease spread was very slow. More cases were reported during summer than autumn. The 18-month prevalence of ASF in areas under various animal movement restrictions was 18.6% among wild boar found dead or killed by vehicles and only 0.2% in hunted wild boar. Repeated introductions of the virus into the country, the primary role of wild boar in virus maintenance, and the slow spread of the disease indicate a need for enhanced biosecurity at pig holdings and continuous and intensive surveillance for fast detection of ASF.

    Petersen, Jakob; Simons, Hilary; Patel, Dipti

    More than 700,000 trips were made by residents in England, Wales, and Northern Ireland (EWNI) in 2015 to tropical countries endemic for yellow fever, a potentially deadly, yet vaccine-preventable disease transmitted by mosquitoes. The aim of this study was to map the geographical accessibility of yellow fever vaccination centres (YFVC) in EWNI. The location of 3208 YFVC were geocoded and the average geodetic distance to nearest YFVC was calculated for each population unit. Data on trips abroad and centres were obtained regionally for EWNI and nationally for the World Top20 countries in terms of travel. The mean distance to nearest YFVC was 2.4 km and only 1% of the population had to travel more than 16.1 km to their nearest centre. The number of vaccines administered regionally in EWNI was found correlated with the number of trips to yellow fever countries. The number of centres per 100,000 trips was 6.1 in EWNI, which was below United States (12.1) and above the rest of Top20 countries. The service availability was in line with demand regionally. With the exception of remote, rural areas, yellow fever vaccination services were widely available with only short distances to cover for the travelling public. Crown Copyright © 2017.

    Estuaries and coastal seas provide valuable ecosystem services but are particularly vulnerable to the co-occurring threats of climate change and oxygen-depleted dead zones. We analyzed the severity of climate change predicted for existing dead zones, and found that 94% of dead zones are in regions that will experience at least a 2 °C temperature increase by the end of the century. We then reviewed how climate change will exacerbate hypoxic conditions through oceanographic, ecological, and physiological processes. We found evidence that suggests numerous climate variables including temperature, ocean acidification, sea-level rise, precipitation, wind, and storm patterns will affect dead zones, and that each of those factors has the potential to act through multiple pathways on both oxygen availability and ecological responses to hypoxia. Given the variety and strength of the mechanisms by which climate change exacerbates hypoxia, and the rates at which climate is changing, we posit that climate change variables are contributing to the dead zone epidemic by acting synergistically with one another and with recognized anthropogenic triggers of hypoxia including eutrophication. This suggests that a multidisciplinary, integrated approach that considers the full range of climate variables is needed to track and potentially reverse the spread of dead zones. © 2014 John Wiley & Sons Ltd.

    The Dead Sea is the lowest point on Earth at 418 meters below sea level, and also one of the saltiest bodies of water on Earth with a salinity of about 300 parts-per-thousand (nine times greater than ocean salinity). It is located on the border between Jordan and Israel, and is fed by the Jordan River. The Dead Sea is located in the Dead Sea Rift, formed as a result of the Arabian tectonic plate moving northward away from the African Plate. The mineral content of the Dead Sea is significantly different from that of ocean water, consisting of approximately 53% magnesium chloride, 37% potassium chloride and 8% sodium chloride. In the early part of the 20th century, the Dead Sea began to attract interest from chemists who deduced that the Sea was a natural deposit of potash and bromine. From the Dead Sea brine, Israel and Jordan produce 3.8 million tons potash, 200,000 tons elemental bromine, 45,000 tons caustic soda, 25, 000 tons magnesium metal, and sodium chloride. Both countries use extensive salt evaporation pans that have essentially diked the entire southern end of the Dead Sea.

    Virus-like particles (VLPs) present viral antigens in a native conformation and are effectively recognized by the immune system and therefore are considered as suitable and safe vaccine candidates against many viral diseases. Here we demonstrate that chimeric VLPs containing Rift Valley fever virus (RVFV) glycoproteins GN and GC, nucleoprotein N and the gag protein of Moloney murine leukemia virus represent an effective vaccine candidate against Rift Valley fever, a deadly disease in humans and livestock. Long-lasting humoral and cellular immune responses are demonstrated in a mouse model by the analysis of neutralizing antibody titers and cytokine secretion profiles. Vaccine efficacy studies were performed in mouse and rat lethal challenge models resulting in high protection rates. Taken together, these results demonstrate that replication-incompetent chimeric RVF VLPs are an efficient RVFV vaccine candidate. PMID:19932911

    2011-01-01

    We present findings from one survey and five experiments carried out in the USA, Nigeria and the Middle East showing that judgements about the use of deadly intergroup violence are strikingly insensitive to quantitative indicators of success, or to perceptions of their efficacy. By demonstrating that judgements about the use of war are bounded by rules of deontological reasoning and parochial commitment, these findings may have implications for understanding the trajectory of violent political conflicts. Further, these findings are compatible with theorizing that links the evolution of within-group altruism to intergroup violence. PMID:21325334

    The DEAD-box RNA helicases are involved in almost every aspect of RNA metabolism, associated with diverse cellular functions including plant growth and development, and their importance in response to biotic and abiotic stresses is only beginning to emerge. However, none of DEAD-box genes was well characterized in tomato so far. In this study, we reported on the identification and characterization of two putative DEAD-box RNA helicase genes, SlDEAD30 and SlDEAD31 from tomato, which were classified into stress-related DEAD-box proteins by phylogenetic analysis. Expression analysis indicated that SlDEAD30 was highly expressed in roots and mature leaves, while SlDEAD31 was constantly expressed in various tissues. Furthermore, the expression of both genes was induced mainly in roots under NaCl stress, and SlDEAD31 mRNA was also increased by heat, cold, and dehydration. In stress assays, transgenic tomato plants overexpressing SlDEAD31 exhibited dramatically enhanced salt tolerance and slightly improved drought resistance, which were simultaneously demonstrated by significantly enhanced expression of multiple biotic and abiotic stress-related genes, higher survival rate, relative water content (RWC) and chlorophyll content, and lower water loss rate and malondialdehyde (MDA) production compared to wild-type plants. Collectively, these results provide a preliminary characterization of SlDEAD30 and SlDEAD31 genes in tomato, and suggest that stress-responsive SlDEAD31 is essential for salt and drought tolerance and stress-related gene regulation in plants.

  9. Did scarlet fever and rheumatic fever exist in Hippocrates' time?

    PubMed

    Quinn, R W

    1991-01-01

    Case histories recorded by Hippocrates around 400 B.C. describe the clinical manifestations of scarlet fever and rheumatic fever, although the entities are not identified by name. Although the descriptions are not as detailed or complete as they would be today, they strongly suggest the existence of scarlet fever and rheumatic fever at that time. Hippocrates' references to these illnesses were presumably the first to be documented and/or discovered, as a thorough search of the worldwide medical literature revealed no prior descriptions.

  10. [The war at home: "war amenorrhea" in the First World War].

    PubMed

    Stukenbrock, Karin

    2008-01-01

    In 1917, the Göttingen gynaecologist Dietrich published a short article about a phenomenon which he called "war amenorrhea" ("Kriegsamenorrhoe"). The article attracted the attention of his colleagues. While the affected women did not pay much attention to their amenorrhea, the physicians considered the phenomenon a new disease which was mainly caused by the war. This new disease gave the gynaecologists the opportunity to present their specialty as a discipline with high relevance for medicine in times of war. Nevertheless, there was no consensus about the importance, the incidence, the diagnostic criteria, the causes and the appropriate therapy of"war amenorrhea". Although the gynaecologists failed to define a uniform clinical syndrome, they maintained the construction of "war amenorrhea" after the war and subsumed it under well known types of amenorrhea. We can conclude that under the conditions of war a new disease emerged which was not sharply defined.

  11. How dead is dead? Qualitative findings from participants of combined traditional and lead-time time trade-off valuations.

    The EuroQol Valuation Technology (EQ-VT) uses traditional time trade-off (tTTO) for health states better than dead and lead-time TTO (LT-TTO) for states worse than dead to elicit a value (-1.0 to +1.0) for each health state. In the Canadian EQ-5D-5L Valuation study which used the EQVT platform, we observed an unexpected peak in frequency of "0" values and few negative values, particularly in the range of 0 to -0.5. To better understand this finding, we sought to explore respondents' thought processes while valuing a health state, and their understanding of the tTTO and LT-TTO exercises. Qualitative semi-structured interviews were conducted with EQVT task respondents. Questions focused on valuations of health states as: (a) Same as dead in tTTO, (b) Worse than dead in tTTO but changed to same as dead in LT-TTO, (c) Worse than dead in LT-TTO, and (d) Worse than dead in LT-TTO with trading off all 10 years. Data were analyzed using content and thematic analysis. Mean age of participants (N = 70) was 40 ± 18.1 years, 60% female, and 76% Caucasian. Participants provided similar reasons for valuing a health state same as or worse than dead. Many participants expressed confusion about worse than dead valuations, distinction between same as and worse than dead, and the transition from tTTO to LT-TTO. A few indicated that the addition of 10 years of full health in the LT-TTO influenced their valuations. The transition from tTTO to LT-TTO in the EQVT was confusing to participants, whereby some health state valuations around this transition appeared to be arbitrary.

    Yellow fever, a mosquito-borne flavivirus disease occurs in tropical areas of South America and Africa. It is a disease of major historical importance, but remains a threat to travelers to and residents of endemic areas despite the availability of an effective vaccine for nearly 70 years. An important aspect is the receptivity of many non-endemic areas to introduction and spread of yellow fever. This paper reviews the clinical aspects, pathogenesis, and epidemiology of yellow fever, with an emphasis on recent changes in the distribution and incidence of the disease. Recent knowledge about yellow fever 17D vaccine mechanism of action and safety are discussed. Copyright © 2014 Elsevier B.V. All rights reserved.

    The aim of this study is to describe the nature of war wounds with fracture caused by cluster bombs and to suggest treatment options for such injuries. The nature of wounds caused by cluster bombs differs from those caused by conventional arms (they are more severe). The sides of the wounds are represented by conquasated soft tissues (such as fat and muscle) with thick dead tissues, ordinarily with a thickness of 0.5-4.5 cm. Another main characteristic of such injuries is the high percentage of amputations needed due to the high rate of neurovascular damage. This paper investigates the cases of 81 patients who sustained a total of 99 war wounds with fractures. The average age of the patients was 32.7 years while the youngest was 20 and the oldest, 77. According to The International Committee of the Red Cross (ICRC) classification of war wounds, 14 patients had grade I injuries, 48 patients grade II, and 29 patients, grade III. Mitkovic external fixation system, known also as the "War Fixator" was used for all fractures fixation. One protocol, which was a modification of the ICRC's protocol adapted to our specific conditions, was used throughout the study. For solving soft tissue defects, a rotator fasciocutan flap was the most frequently used. For solving of bones defect Mitkovic reconstructive external fixation device was used. All fractures we treated healed. We concluded that shortening the procedural time and being a very simple, immediate using of Mitkovic versatile external fixator ("War Fixator") is, leads to desirable results.

  15. Fever in sepsis.

    PubMed

    Schortgen, F

    2012-11-01

    Fever is a common symptom of sepsis usually believed to predict better survival. Experimental data suggest that body temperature elevation may slow micro-organism growth and enhance host immune responses. In patients with sepsis, however, the high energy cost of fever may exacerbate the life-threatening situation. Fever control is widely used in the ICU, mainly in patients with infections. The efficacy of antipyretic drugs in lowering body temperature remains uncertain, however, and all antipyretics have well known adverse effects. Surface cooling methods are efficient but require sedation to avoid the harmful effects of shivering. A recent controlled trial in patients with septic shock suggests that external cooling for fever control may diminish vasopressor requirements and improve early survival. In this review, we examine the benefits and risks of fever and of controlled normothermia. The fever control modalities that provide the best risk/benefit ratio in sepsis are discussed.

    Background Rift Valley Fever (RVF), is a viral zoonotic disease transmitted by Aedes and Culex mosquitoes. In Kenya, its occurrence is associated with increased rains. In Baringo County, RVF was first reported in 2006–2007 resulting in 85 human cases and 5 human deaths, besides livestock losses and livelihood disruptions. This study sought to investigate the county’s current RVF risk status. Methodology and principal findings A cross-sectional study on the knowledge, attitudes and practices of RVF was conducted through a mixed methods approach utilizing a questionnaire survey (n = 560) and 26 focus group discussions (n = 231). Results indicate that study participants had little knowledge of RVF causes, its signs and symptoms and transmission mechanisms to humans and livestock. However, most of them indicated that a person could be infected with zoonotic diseases through consumption of meat (79.2%) and milk (73.7%) or contact with blood (40%) from sick animals. There was a statistically significant relationship between being male and milking sick animals, consumption of milk from sick animals, consuming raw or cooked blood, slaughtering sick livestock or dead animals for consumption (all at p≤0.001), and handling sick livestock with bare hands (p = 0.025) with more men than women engaging in the risky practices. Only a few respondents relied on trained personnel or local experts to inspect meat for safety of consumption every time they slaughtered an animal at home. Sick livestock were treated using conventional and herbal medicines often without consulting veterinary officers. Conclusions Communities in Baringo County engage in behaviour that may increase their risk to RVF infections during an outbreak. The authors recommend community education to improve their response during outbreaks. PMID:28542242

    Objective: Through analyzing the surveillance data on typhoid fever and paratyphoid fever in 2015 to understand the related epidemiological features and most possible clustering areas of high incidence. Methods: Individual data was collected from the passive surveillance program and analyzed by descriptive statistic method. Characteristics on seasonal, regional and distribution of the diseases were described. Spatial-temporal clustering characteristics were estimated, under the retrospective space-time method. Results: A total of 8 850 typhoid fever cases were reported from the surveillance system, with incidence rate as 0.65/100 000. The number of paratyphoid fever cases was 2 794, with incidence rate as 0.21/100 000. Both cases of typhoid fever and paratyphoid fever occurred all year round, with high epidemic season from May to October. Most cases involved farmers (39.68 % ), children (15.89 % ) and students (12.01 % ). Children under 5 years showed the highest incidence rate. Retrospective space-time analysis for provinces with high incidence rates would include Yunnan, Guangxi, Guizhou, Hunan and Guangdong, indicating the first and second class clusters were mainly distributed near the bordering adjacent districts and counties among the provinces. Conclusion: In 2015, the prevalence rates of typhoid fever and paratyphoid fever were low, however with regional high prevalence areas. Cross regional transmission existed among provinces with high incidence rates which might be responsible for the clusters to appear in these areas.

    The early 20th century Southerner lived in a disease environment created by a confluence of poverty, climate and the legacy of slavery. A deadly trio of pellagra, hookworm and malaria enervated the poor Southerner--man, woman and child--creating a dull, weakened people ill equipped to prosper in the modem world. The Northern perceptions of the South as a backward and sickly region were only compounded by the realization that her population was malnourished, infected by worms, and continually plagued by agues and fevers. As historian John Duffy concluded, "As a chronically debilitating disease, it [malaria] shared with the other two the responsibility for the term 'lazy Southerner".

    Coxiella burnetii causes Q fever, a zoonosis, which has acute and chronic manifestations. From 2007 to 2010, the Netherlands experienced a large Q fever outbreak, which has offered a unique opportunity to analyze chronic Q fever cases. In an observational cohort study, baseline characteristics and clinical characteristics, as well as mortality, of patients with proven, probable, or possible chronic Q fever in the Netherlands, were analyzed. In total, 284 chronic Q fever patients were identified, of which 151 (53.7%) had proven, 64 (22.5%) probable, and 69 (24.3%) possible chronic Q fever. Among proven and probable chronic Q fever patients, vascular infection focus (56.7%) was more prevalent than endocarditis (34.9%). An acute Q fever episode was recalled by 27.0% of the patients. The all-cause mortality rate was 19.1%, while the chronic Q fever-related mortality rate was 13.0%, with mortality rates of 9.3% among endocarditis patients and 18% among patients with a vascular focus of infection. Increasing age (P = 0.004 and 0.010), proven chronic Q fever (P = 0.020 and 0.002), vascular chronic Q fever (P = 0.024 and 0.005), acute presentation with chronic Q fever (P = 0.002 and P < 0.001), and surgical treatment of chronic Q fever (P = 0.025 and P < 0.001) were significantly associated with all-cause mortality and chronic Q fever-related mortality, respectively.

    Unclaimed dead are deceased persons with no known next of kin (NoK) or NoK was located but did not claim the deceased. Unclaimed dead in Marion County, Indiana, 2004-2011, are examined. Comparisons are provided of the unclaimed to the claimed dead population and county death patterns. Race, gender, marital status, age, location, manner and cause of death, NoK, and days to disposition are analyzed. The unclaimed dead were disproportionately male, slightly more likely to be Black, younger at death, died from natural causes, had unknown marital status, were equally likely as not to have NoK, did not die in a hospital, and were subject to autopsy. Nearly half the unclaimed had NoK who did not claim the body; the other half had no identifiable NoK. Unclaimed were more likely to have an autopsy and to die from external causes. Most unclaimed were identified by means outside fingerprints or DNA. © 2015 American Academy of Forensic Sciences.

    Summary The Semple antirabies vaccine was developed by David Semple in India in 1911. Semple introduced a peculiarly British approach within the Pasteurian tradition by using carbolized dead virus. This article studies this unique phase of vaccine research between 1910 and 1935 to show that in the debates and laboratory experiments around the potency and safety of vaccines, categories like "living" and "dead" were often used as ideological and moral denominations. These abstract and ideological debates were crucial in defining the final configuration of the Semple vaccine, the most popular antirabies vaccine used globally, and also in shaping international vaccination policies.

    During a series of epizootics caused by Yellow fever virus in Brazil between 2007 and 2009, a monkey was found dead (May 2009) in a sylvatic area in the State of Paraná. Brain samples from this animal were used for immunohistochemical analysis and isolation of a wild-type strain of YFV. This viral strain was characterized, and sequence analyzes demonstrated that it is closely related with YFV strains of the recently identified subclade 1E of the South American genotype I. Further characterization included indirect-immunofluorescence of different infected cell lines and analysis of the kinetics of virus replication and infectivity inhibition by type I IFN. The generated data contributes to the knowledge of YFV evolution and phylogeny. Additionally, the reagents generated and characterized during this study, such as a panel of monoclonal antibodies, are useful tools for further studies on YFV. Lastly, this case stresses the importance of yellow fever surveillance through sentinel monkeys. Copyright © 2016 Elsevier B.V. All rights reserved.

    In Poland, African swine fever (ASF) emerged in February 2014; by August 2015, the virus had been detected in >130 wild boar and in pigs in 3 backyard holdings. We evaluated ASF spread in Poland during these 18 months. Phylogenetic analysis indicated repeated incursions of genetically distinct ASF viruses of genotype II; the number of cases positively correlated wild boar density; and disease spread was very slow. More cases were reported during summer than autumn. The 18-month prevalence of ASF in areas under various animal movement restrictions was 18.6% among wild boar found dead or killed by vehicles and only 0.2% in hunted wild boar. Repeated introductions of the virus into the country, the primary role of wild boar in virus maintenance, and the slow spread of the disease indicate a need for enhanced biosecurity at pig holdings and continuous and intensive surveillance for fast detection of ASF.

    Infectious diseases were one of the first health threats confronted by Coalition troops deployed to the Arabian desert in August 1990. On the basis of experiences in World War II, the major endemic infectious disease risks were thought to be sandfly fever, cutaneous leishmaniasis, diarrheal disease, and malaria. Although there was active surveillance, no case of sandfly fever and few other endemic infectious diseases were identified among over 500,000 U.S., British, and Canadian ground troops. In addition, there was no diagnosis of biological warfare (BW) exposure, and BW agents were not detected in clinical, environmental, or veterinary samples. The most common infectious disease problems were those associated with crowding (acute upper respiratory infections) and reduced levels of sanitation (travelers-type diarrhea). Only one endemic infectious disease has been confirmed as causing chronic health problems: visceral Leishmania tropica infection (viscerotropic leishmaniasis). However, this protozoan infection was diagnosed in only 12 U.S. veterans, and no new cases have been identified during the last 8 years. Infectious diseases were not a serious problem for Gulf War troops because of extensive preventive medicine efforts and favorable weather and geographic factors. Moreover, it is unlikely that an endemic infectious disease or a BW agent could cause chronic health problems and remain undetected over a 10-year period.

    Rift Valley Fever epizootics are characterized by numerous abortions and mortality among young animals. In humans, the illness is usually characterized by a mild self-limited febrile illness, which could progress to more serious complications.Objectives. The aim of the present prospective study was to describe severe clinical signs and symptoms of Rift Valley Fever in southern Mauritania. Suspected cases were enrolled in Kiffa (Assaba) and Aleg (Brakna) Hospital Centers from September 1 to November 7, 2015, based on the presence of fever, hemorrhagic or meningoencephalitic syndromes, and probable contact with sick animals. Suspected cases were confirmed by enzyme-linked immunosorbent assay (ELISA) and reverse transcriptase-polymerase chain reaction (RT-PCR). There were thirty-one confirmed cases. The sex ratio M/F and the average age were 2.9 and 25 years old [range, 4-70 years old], respectively. Mosquito bites, direct contact with aborted or dead animals, and frequent ingestion of milk from these animals were risk factors observed in all patients. Hemorrhagic and neurological manifestations were observed in 81% and 13% of cases, respectively. The results of laboratory analysis showed high levels of transaminases, creatinine, and urea associated with thrombocytopenia, anemia, and leukopenia. All patients who died (42%) had a hemorrhagic syndrome and 3 of them had a neurological complication. Among the cured patients, none had neurologic sequelae. The hemorrhagic form was the most common clinical manifestation of RVF found in southern Mauritania and was responsible for a high mortality rate. Our results justify the implementation of a continuous epidemiological surveillance.

  5. Assessment and management of dead-wood habitat

    2007-01-01

    The Bureau of Land Management (BLM) is in the process of revising its resource management plans for six districts in western and southern Oregon as the result of the settlement of a lawsuit brought by the American Forest Resource Council. A range of management alternatives is being considered and evaluated including at least one that will minimize reserves on O&C lands. In order to develop the bases for evaluating management alternatives, the agency needs to derive a reasonable range of objectives for key issues and resources. Dead-wood habitat for wildlife has been identified as a key resource for which decision-making tools and techniques need to be refined and clarified. Under the Northwest Forest Plan, reserves were to play an important role in providing habitat for species associated with dead wood (U.S. Department of Agriculture Forest Service and U.S. Department of the Interior Bureau of Land Management, 1994). Thus, the BLM needs to: 1) address the question of how dead wood will be provided if reserves are not included as a management strategy in the revised Resource Management Plan, and 2) be able to evaluate the effects of alternative land management approaches. Dead wood has become an increasingly important conservation issue in managed forests, as awareness of its function in providing wildlife habitat and in basic ecological processes has dramatically increased over the last several decades (Laudenslayer et al., 2002). A major concern of forest managers is providing dead wood habitat for terrestrial wildlife. Wildlife in Pacific Northwest forests have evolved with disturbances that create large amounts of dead wood; so, it is not surprising that many species are closely associated with standing (snags) or down, dead wood. In general, the occurrence or abundance of one-quarter to one-third of forest-dwelling vertebrate wildlife species, is strongly associated with availability of suitable dead-wood habitat (Bunnell et al., 1999; Rose et al., 2001).

    2007-01-01

    Aim To present a summary of the organization, field search, repatriation, forensic anthropological examination, and DNA analysis for the purpose of identification of Finnish soldiers with unresolved fate in World War II. Methods Field searches were organized, executed, and financed by the Ministry of Education and the Association for Cherishing the Memory of the Dead of the War. Anthropological examination conducted on human remains retrieved in the field searches was used to establish the minimum number of individuals and description of the skeletal diseases, treatment, anomalies, or injuries. DNA tests were performed by extracting DNA from powdered bones and blood samples from relatives. Mitochondrial DNA (mtDNA) sequence comparisons, together with circumstantial evidence, were used to connect the remains to the putative family members. Results At present, the skeletal remains of about a thousand soldiers have been found and repatriated. In forensic anthropological examination, several injuries related to death were documented. For the total of 181 bone samples, mtDNA HVR-1 and HVR-2 sequences were successfully obtained for 167 (92.3%) and 148 (81.8%) of the samples, respectively. Five samples yielded no reliable sequence data. Our data suggests that mtDNA preserves at least for 60 years in the boreal acidic soil. The quality of the obtained mtDNA sequence data varied depending on the sample bone type, with long compact bones (femur, tibia and humerus) having significantly better (90.0%) success rate than other bones (51.2%). Conclusion Although more than 60 years have passed since the World War II, our experience is that resolving the fate of soldiers missing in action is still of uttermost importance for people having lost their relatives in the war. Although cultural and individual differences may exist, our experience presented here gives a good perspective on the importance of individual identification performed by forensic professionals.

    Fever with rashes is one of the commonest clinical problems a general practitioner or pediatrician has to face in day-to-day clinical practice. It can be a mild viral illness or a life-threatening illness like meningococcemia or Dengue hemorrhagic fever or it can be one with a lifelong consequence like Kawasaki disease. It is very important to arrive at a clinical diagnosis as early as possible with the minimum investigational facilities. The common causes associated with fever and rashes are infections, viral followed by other infections. There can be so many non-infectious causes also for fever and rashes like auto immune diseases, drug allergies etc. The type of rashes, their appearance in relation to the fever and pattern of spread to different parts of body and the disappearance, all will help in making a diagnosis. Often the diagnosis is clinical. In certain situations laboratory work up becomes essential.

    2015-08-21

    Rift valley fever (RVF) is a re-emerging viral vector-borne disease with rapid global socio-economic impact. A large RVF outbreak occurred in Tanzania in 2007 and affected more than half of the regions with high (47 %) case fatality rate. Little is known about RVF and its dynamics. A cross sectional study was conducted to assess the knowledge, attitudes and practices regarding RVF in Kongwa and Kilombero districts, Tanzania. We conducted a cross sectional survey among a randomly selected sample of individuals in 2011. We administered questionnaires to collect data on demographic characteristics, knowledge on symptoms, mode of transmission, prevention, attitudes and health seeking practices. A total of 463 community members participated in this study. The mean (±SD) age was 39.8 ± 14.4 years and 238 (51.4 %) were female. Majority of respondents had heard of RVF. However, only 8.8 % knew that mosquitoes were transmitting vectors. Male respondents were more likely to have greater knowledge about RVF. A small proportion mentioned clinical signs and symptoms of RVF in animals while 73.7 % mentioned unhealthy practices related to handling and consumption of dead animals. Thorough boiling of milk and cooking of meat were commonly mentioned as preventive measures for RVF. Majority (74.6 %) sought care for febrile illness at health facilities. Few (24.3 %) reported the use of protective gears to handle dead/sick animal while 15.5 % were consuming dead animals. Our study highlights the need to address the limited knowledge about RVF and promoting appropriate and timely health seeking practices. Rift valley fever outbreaks can be effectively managed with collaborative efforts of lay and professional communities with a shared perception that it poses a serious threat to public and animal health. The fact that this study was conducted in "high risk transmission areas" warrants further inquiry in other geographic regions with relatively low risk of RVF.

    NASA Astrophysics Data System (ADS)

    2000-03-01

    Communicating with dead persons is popular in the new paranatural (paranormal-spiritual) paradigm that has emerged today. This view violates physicalist principles. Scientists have investigated survival questions for over 150 years. Beginning with the Fox sisters in 1848, they have examined reports of apparitions and ghosts, rappings, table turnings, teleportation, levitation, and other alleged physicalist manifestations in séances. Such reports were discredited by uncovering hoaxes by alleged mediums, e.g. Eusapia Palladino (1910s), Marjorie Crandon (1920s), etc. In recent decades there has been a revival of interest in survival with reports of near-death experiences. Skeptics ask: Are such persons clinically dead? Today, channelers such as James Van Praagh, John Edwards, and Sylvia Browne claim to communicate directly with the dead (the "Sixth Sense"). There is no attempt at physical confirmation or independent eyewitness corroboration so essential for scientific inquiry. Subjective claims are uncritically accepted at their face value, though alternative naturalistic explanations can be given for the alleged phenomena.

  14. TURBULENCE, TRANSPORT, AND WAVES IN OHMIC DEAD ZONES

    DOE Office of Scientific and Technical Information (OSTI.GOV)

    Gole, Daniel; Simon, Jacob B.; Armitage, Philip J.

    We use local numerical simulations to study a vertically stratified accretion disk with a resistive mid-plane that damps magnetohydrodynamic (MHD) turbulence. This is an idealized model for the dead zones that may be present at some radii in protoplanetary and dwarf novae disks. We vary the relative thickness of the dead and active zones to quantify how forced fluid motions in the dead zone change. We find that the residual Reynolds stress near the mid-plane decreases with increasing dead zone thickness, becoming negligible in cases where the active to dead mass ratio is less than a few percent. This impliesmore » that purely Ohmic dead zones would be vulnerable to episodic accretion outbursts via the mechanism of Martin and Lubow. We show that even thick dead zones support a large amount of kinetic energy, but this energy is largely in fluid motions that are inefficient at angular momentum transport. Confirming results from Oishi and Mac Low, the perturbed velocity field in the dead zone is dominated by an oscillatory, vertically extended circulation pattern with a low frequency compared to the orbital frequency. This disturbance has the properties predicted for the lowest order r mode in a hydrodynamic disk. We suggest that in a global disk similar excitations would lead to propagating waves, whose properties would vary with the thickness of the dead zone and the nature of the perturbations (isothermal or adiabatic). Flows with similar amplitudes would buckle settled particle layers and could reduce the efficiency of pebble accretion.« less

    Yellow fever continues to occur in regions of Africa and South America, despite the availability of effective vaccines. Recently, some cases of severe neurologic disease and multiorgan system disease have been described in individuals who received yellow fever vaccine. These events have focused attention on the need to define criteria for judicious use of yellow fever vaccine and to describe the spectrum of adverse events that may be associated with yellow fever vaccine. Describing host factors that would increase risk of these events and identifying potential treatment modalities for yellow fever and yellow fever vaccine-associated adverse events are subjects of intense investigation.

    Fever is an evolutionary conserved defense mechanism which is present in both endothermic and ectothermic vertebrates. Ectotherms in response to infection can increase their body temperature by moving to warmer places. This process is known as behavioral fever. In this review, we summarize the current knowledge on the mechanisms of induction of fever in mammals. We further discuss the evolutionary conserved mechanisms existing between fever of mammals and behavioral fever of ectothermic vertebrates. Finally, the experimental evidences supporting an adaptive value of behavioral fever expressed by ectothermic vertebrates are summarized. Copyright © 2016 Elsevier Ltd. All rights reserved.

  17. The dead donor rule: a defense.

    PubMed

    Birch, Samuel C M

    2013-08-01

    Miller, Truog, and Brock have recently argued that the "dead donor rule," the requirement that donors be determined to be dead before vital organs are procured for transplantation, cannot withstand ethical scrutiny. In their view, the dead donor rule is inconsistent with existing life-saving practices of organ transplantation, lacks a cogent ethical rationale, and is not necessary for maintenance of public trust in organ transplantation. In this paper, the second of these claims will be evaluated. (The first and third are not addressed.) The claim that the dead donor rule lacks a cogent ethical rationale will be shown to be an expression of the contemporary rejection of the moral significance of the traditional distinction between killing and allowing to die. The moral significance of this traditional distinction, and the associated norm that doctors should not kill their patients, will be defended, and this critique of it shown to be unsuccessful.

  18. Fever: a concept analysis

    Thompson, Hilaire J.

    2008-01-01

    Aim The purpose of this paper is to critically analyse the current state of the science literature in order to develop an accurate conception of fever. Rationale The measurement of body temperature and treatment of fever have long been considered to be within the domain of nursing practice. What body temperature constitutes ‘fever’, however, is often not clear from nursing protocols or the literature. Methods Literature for this concept analysis was obtained by computerized searches of PubMed, CINAHL and BIOSYS for the years 1980−2004. Additional sources were obtained after reviewing the bibliographies of the literature identified by the initial search. The Wilsonian method of concept analysis provided the framework for the analysis. Findings Fever has characteristically been recognized as a cardinal sign of illness and has traditionally had negative connotations for patient well-being. Substantive advances over the past 20 years in immunology and neurophysiology have expanded understanding of the process of fever. This new knowledge has shifted the perception of fever as part of the acute-phase response to one of an adaptive nature. This knowledge has yet to be fully translated into changes in the fever management practices of nurses. Conclusions Consistent usage of terminology in relation to fever should lead to improved and evidence-based care for patients, and to fever management practices consistent with current research. It is important to use clear language about fever and hyperthermia in discussions and documentation between nurses and among disciplines. By creating clarity in our language, we may help to achieve praxis. PMID:16098165

  4. Dead time corrections using the backward extrapolation method

    2017-05-01

    Dead time losses in neutron detection, caused by both the detector and the electronics dead time, is a highly nonlinear effect, known to create high biasing in physical experiments as the power grows over a certain threshold, up to total saturation of the detector system. Analytic modeling of the dead time losses is a highly complicated task due to the different nature of the dead time in the different components of the monitoring system (e.g., paralyzing vs. non paralyzing), and the stochastic nature of the fission chains. In the present study, a new technique is introduced for dead time corrections on the sampled Count Per Second (CPS), based on backward extrapolation of the losses, created by increasingly growing artificially imposed dead time on the data, back to zero. The method has been implemented on actual neutron noise measurements carried out in the MINERVE zero power reactor, demonstrating high accuracy (of 1-2%) in restoring the corrected count rate.

  5. Mechanisms of fever production and lysis: lessons from experimental LPS fever.

    PubMed

    Roth, Joachim; Blatteis, Clark M

    2014-10-01

    Fever is a cardinal symptom of infectious or inflammatory insults, but it can also arise from noninfectious causes. The fever-inducing agent that has been used most frequently in experimental studies designed to characterize the physiological, immunological and neuroendocrine processes and to identify the neuronal circuits that underlie the manifestation of the febrile response is lipopolysaccharide (LPS). Our knowledge of the mechanisms of fever production and lysis is largely based on this model. Fever is usually initiated in the periphery of the challenged host by the immediate activation of the innate immune system by LPS, specifically of the complement (C) cascade and Toll-like receptors. The first results in the immediate generation of the C component C5a and the subsequent rapid production of prostaglandin E2 (PGE2). The second, occurring after some delay, induces the further production of PGE2 by induction of its synthesizing enzymes and transcription and translation of proinflammatory cytokines. The Kupffer cells (Kc) of the liver seem to be essential for these initial processes. The subsequent transfer of the pyrogenic message from the periphery to the brain is achieved by neuronal and humoral mechanisms. These pathways subserve the genesis of early (neuronal signals) and late (humoral signals) phases of the characteristically biphasic febrile response to LPS. During the course of fever, counterinflammatory factors, "endogenous antipyretics," are elaborated peripherally and centrally to limit fever in strength and duration. The multiple interacting pro- and antipyretic signals and their mechanistic effects that underlie endotoxic fever are the subjects of this review.

  11. Discriminating fever behavior in house flies.

    PubMed

    Anderson, Robert D; Blanford, Simon; Jenkins, Nina E; Thomas, Matthew B

    2013-01-01

    Fever has generally been shown to benefit infected hosts. However, fever temperatures also carry costs. While endotherms are able to limit fever costs physiologically, the means by which behavioral thermoregulators constrain these costs are less understood. Here we investigated the behavioral fever response of house flies (Musca domestica L.) challenged with different doses of the fungal entomopathogen, Beauveria bassiana. Infected flies invoked a behavioral fever selecting the hottest temperature early in the day and then moving to cooler temperatures as the day progressed. In addition, flies infected with a higher dose of fungus exhibited more intense fever responses. These variable patterns of fever are consistent with the observation that higher fever temperatures had greater impact on fungal growth. The results demonstrate the capacity of insects to modulate the degree and duration of the fever response depending on the severity of the pathogen challenge and in so doing, balance the costs and benefits of fever.

  12. AMP sensing by DEAD-box RNA helicases

    PubMed Central

    Putnam, Andrea A.; Jankowsky, Eckhard

    2013-01-01

    In eukaryotes, cellular levels of adenosine monophosphate (AMP) signal the metabolic state of the cell. AMP concentrations increase significantly upon metabolic stress, such as glucose deprivation in yeast. Here we show that several DEAD-box RNA helicases are sensitive to AMP, which is not produced during ATP hydrolysis by these enzymes. We find that AMP potently inhibits RNA binding and unwinding by the yeast DEAD-box helicases Ded1p, Mss116p, and eIF4A. However, the yeast DEAD-box helicases Sub2p and Dbp5p are not inhibited by AMP. Our observations identify a subset of DEAD-box helicases as enzymes with the capacity to directly link changes in AMP concentrations to RNA metabolism. PMID:23702290

  13. Dead pixel replacement in LWIR microgrid polarimeters.

    PubMed

    Ratliff, Bradley M; Tyo, J Scott; Boger, James K; Black, Wiley T; Bowers, David L; Fetrow, Matthew P

    2007-06-11

    LWIR imaging arrays are often affected by nonresponsive pixels, or "dead pixels." These dead pixels can severely degrade the quality of imagery and often have to be replaced before subsequent image processing and display of the imagery data. For LWIR arrays that are integrated with arrays of micropolarizers, the problem of dead pixels is amplified. Conventional dead pixel replacement (DPR) strategies cannot be employed since neighboring pixels are of different polarizations. In this paper we present two DPR schemes. The first is a modified nearest-neighbor replacement method. The second is a method based on redundancy in the polarization measurements.We find that the redundancy-based DPR scheme provides an order-of-magnitude better performance for typical LWIR polarimetric data.

    Scaravilli, V; Tinchero, G; Citerio, G

    2011-09-01

    An electronic literature search through August 2010 was performed to obtain articles describing fever incidence, impact, and treatment in patients with subarachnoid hemorrhage. A total of 24 original research studies evaluating fever in SAH were identified, with studies evaluating fever and outcome, temperature control strategies, and shivering. Fever during acute hospitalization for subarachnoid hemorrhage was consistently linked with worsened outcome and increased mortality. Antipyretic medications, surface cooling, and intravascular cooling may all reduce temperatures in patients with subarachnoid hemorrhage; however, benefits from cooling may be offset by negative consequences from shivering.

    PubMed Central

    1998-01-01

    Dengue fever, a very old disease, has reemerged in the past 20 years with an expanded geographic distribution of both the viruses and the mosquito vectors, increased epidemic activity, the development of hyperendemicity (the cocirculation of multiple serotypes), and the emergence of dengue hemorrhagic fever in new geographic regions. In 1998 this mosquito-borne disease is the most important tropical infectious disease after malaria, with an estimated 100 million cases of dengue fever, 500,000 cases of dengue hemorrhagic fever, and 25,000 deaths annually. The reasons for this resurgence and emergence of dengue hemorrhagic fever in the waning years of the 20th century are complex and not fully understood, but demographic, societal, and public health infrastructure changes in the past 30 years have contributed greatly. This paper reviews the changing epidemiology of dengue and dengue hemorrhagic fever by geographic region, the natural history and transmission cycles, clinical diagnosis of both dengue fever and dengue hemorrhagic fever, serologic and virologic laboratory diagnoses, pathogenesis, surveillance, prevention, and control. A major challenge for public health officials in all tropical areas of the world is to devleop and implement sustainable prevention and control programs that will reverse the trend of emergent dengue hemorrhagic fever.

  10. QUAD fever: beware of non-infectious fever in high spinal cord injuries.

    PubMed

    Goyal, Jyoti; Jha, Rakesh; Bhatia, Paramjeet; Mani, Raj Kumar

    2017-06-18

    A case of cervical spinal cord injury and quadriparesis with prolonged fever is being described. Initially, the patient received treatment for well-documented catheter-related bloodstream infection. High spiking fever returned and persisted with no obvious evidence of infection. The usual non-infectious causes too were carefully excluded. QUAD fever or fever due to spinal cord injury itself was considered. The pathogenetic basis of QUAD fever is unclear but could be attributed to autonomic dysfunction and temperature dysregulation. Awareness of this little known condition could help in avoiding unnecessary antimicrobial therapy and in more accurate prognostication. Unlike several previous reported cases that ended fatally, the present case ran a relatively benign course. The spectrum of presentations may therefore be broader than hitherto appreciated. © BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2017. All rights reserved.

  11. The reasons why Pakistan might be at high risk of Crimean Congo haemorrhagic fever epidemic; a scoping review of the literature.

    PubMed

    Atif, Muhammad; Saqib, Anum; Ikram, Raazeyah; Sarwar, Muhammad Rehan; Scahill, Shane

    2017-03-23

    Pakistan has faced a number of significant healthcare challenges over the past decade. In 2000, one of these events - a deadly epidemic of Crimean Congo Haemorrhagic Fever (CCHF) - struck Pakistan. The people of Pakistan are at a very high risk of acquiring CCHF, due to a number of factors which emerge from a scoping review of the literature. First, the underdeveloped healthcare system of the country is currently not prepared to cope with challenges of this nature. Healthcare professionals and medical institutes are not sufficiently equipped to properly diagnose, manage and prevent CCHF. Second, a large percentage of the general public is unaware of the spread and control of the vector. The agricultural sector of Pakistan is vast and thus many people are involved in animal husbandry and the handling of livestock which can lead to the transmission of the CCHF virus. Even in urban areas the risk of transmission is significantly higher around the time of Eid-ul-Azha, when Muslims slaughter animals. Finally, the political upheavals faced by the country have also increased Pakistan's vulnerability because a large number of refugees from Afghanistan, a CCHF endemic country, have migrated to Pakistan as a result of the Afghan war. Most of the refugees and their animals settle in Baluchistan and Khyber Pakhtunkhwa provinces, which consequently have a higher prevalence of CCHF. This scoping review of the literature highlights the potential causes of high risk CCHF and draws conclusions and makes recommendations that policy-makers in Pakistan may wish to consider in-order to improve on the current situation.

  17. Typhoid fever and paratyphoid fever: Systematic review to estimate global morbidity and mortality for 2010

    PubMed Central

    Buckle, Geoffrey C.; Walker, Christa L. Fischer; Black, Robert E.

    2012-01-01

    Background Typhoid and paratyphoid fever remain important causes of morbidity worldwide. Accurate disease burden estimates are needed to guide policy decisions and prevention and control strategies. Methods We conducted a systematic literature review of the PubMed and Scopus databases using pre-defined criteria to identify population-based studies with typhoid fever incidence data published between 1980 and 2009. We also abstracted data from annual reports of notifiable diseases in countries with advanced surveillance systems. Typhoid and paratyphoid fever input data were grouped into regions and regional incidence and mortality rates were estimated. Incidence data were extrapolated across regions for those lacking data. Age-specific incidence rates were derived for regions where age-specific data were available. Crude and adjusted estimates of the global typhoid fever burden were calculated. Results Twenty-five studies were identified, all of which contained incidence data on typhoid fever and 12 on paratyphoid fever. Five advanced surveillance systems contributed data on typhoid fever; 2 on paratyphoid fever. Regional typhoid fever incidence rates ranged from <0.1/100 000 cases/y in Central and Eastern Europe and Central Asia to 724.6/100 000 cases/y in Sub-Saharan Africa. Regional paratyphoid incidence rates ranged from 0.8/100 000 cases/y in North Africa/Middle East to 77.4/100 000 cases/y in Sub-Saharan Africa and South Asia. The estimated total number of typhoid fever episodes in 2010 was 13.5 million (interquartile range 9.1–17.8 million). The adjusted estimate accounting for the low sensitivity of blood cultures for isolation of the bacteria was 26.9 million (interquartile range 18.3–35.7 million) episodes. These findings are comparable to the most recent analysis of global typhoid fever morbidity, which reported crude and adjusted estimates of 10.8 million and 21.7 million typhoid fever episodes globally in 2000. Conclusion Typhoid fever

  3. Respect for the dead and the ethics of anatomy.

    PubMed

    Wilkinson, T M

    2014-04-01

    Dead bodies are not persons but nor are they just things. What, ethically speaking, do the living owe the dead when it comes to using their bodies in anatomy? The article begins with the general question of respect for the dead. It distinguishes between why we should respect the dead, how we should respect them, and the weight to be given to respect. It sets out an account of the reason to respect the dead based on their interests. The article then turns to how the dead should be respected and the importance of doing so. Specifically, it considers three ethical issues in anatomy: the role of the family, the use of unclaimed bodies, and the public display of bodies donated for that purpose. This article claims that what it is to respect the dead is substantially determined by their wishes. Nonetheless the article argues that respect is consistent with allowing the family to veto anatomical use even when the deceased has consented because respect for the dead does not require following all their possible wishes. Respect is also consistent with using unclaimed bodies to which no one--deceased or family--has consented because the interests of the dead do not directly require consent and the interests of the family are unlikely to be relevant. Finally, the article does not see anything disrespectful in the public display of the bodies of those who have consented. Copyright © 2013 Wiley Periodicals, Inc.

  4. Cofactor-dependent specificity of a DEAD-box protein.

    PubMed

    Young, Crystal L; Khoshnevis, Sohail; Karbstein, Katrin

    2013-07-16

    DEAD-box proteins, a large class of RNA-dependent ATPases, regulate all aspects of gene expression and RNA metabolism. They can facilitate dissociation of RNA duplexes and remodeling of RNA-protein complexes, serve as ATP-dependent RNA-binding proteins, or even anneal duplexes. These proteins have highly conserved sequence elements that are contained within two RecA-like domains; consequently, their structures are nearly identical. Furthermore, crystal structures of DEAD-box proteins with bound RNA reveal interactions exclusively between the protein and the RNA backbone. Together, these findings suggest that DEAD-box proteins interact with their substrates in a nonspecific manner, which is confirmed in biochemical experiments. Nevertheless, this contrasts with the need to target these enzymes to specific substrates in vivo. Using the DEAD-box protein Rok1 and its cofactor Rrp5, which both function during maturation of the small ribosomal subunit, we show here that Rrp5 provides specificity to the otherwise nonspecific biochemical activities of the Rok1 DEAD-domain. This finding could reconcile the need for specific substrate binding of some DEAD-box proteins with their nonspecific binding surface and expands the potential roles of cofactors to specificity factors. Identification of helicase cofactors and their RNA substrates could therefore help define the undescribed roles of the 19 DEAD-box proteins that function in ribosome assembly.

    PubMed

    Sakkas, Hercules; Bozidis, Petros; Franks, Ashley; Papadopoulou, Chrissanthy

    2018-04-04

    Oropouche fever is an emerging zoonotic disease caused by Oropouche virus (OROV), an arthropod transmitted Orthobunyavirus circulating in South and Central America. During the last 60 years, more than 30 epidemics and over half a million clinical cases attributed to OROV infection have been reported in Brazil, Peru, Panama, Trinidad and Tobago. OROV fever is considered the second most frequent arboviral febrile disease in Brazil after dengue fever. OROV is transmitted through both urban and sylvatic transmission cycles, with the primary vector in the urban cycle being the anthropophilic biting midge Culicoides paraensis . Currently, there is no evidence of direct human-to-human OROV transmission. OROV fever is usually either undiagnosed due to its mild, self-limited manifestations or misdiagnosed because its clinical characteristics are similar to dengue, chikungunya, Zika and yellow fever, including malaria as well. At present, there is no specific antiviral treatment, and in the absence of a vaccine for effective prophylaxis of human populations in endemic areas, the disease prevention relies solely on vector control strategies and personal protection measures. OROV fever is considered to have the potential to spread across the American continent and under favorable climatic conditions may expand its geographic distribution to other continents. In view of OROV's emergence, increased interest for formerly neglected tropical diseases and within the One Health concept, the existing knowledge and gaps of knowledge on OROV fever are reviewed.

  7. ON HYDRODYNAMIC MOTIONS IN DEAD ZONES

    We investigate fluid motions near the midplane of vertically stratified accretion disks with highly resistive midplanes. In such disks, the magnetorotational instability drives turbulence in thin layers surrounding a resistive, stable dead zone. The turbulent layers in turn drive motions in the dead zone. We examine the properties of these motions using three-dimensional, stratified, local, shearing-box, non-ideal, magnetohydrodynamical simulations. Although the turbulence in the active zones provides a source of vorticity to the midplane, no evidence for coherent vortices is found in our simulations. It appears that this is because of strong vertical oscillations in the dead zone. By analyzingmore » time series of azimuthally averaged flow quantities, we identify an axisymmetric wave mode particular to models with dead zones. This mode is reduced in amplitude, but not suppressed entirely, by changing the equation of state from isothermal to ideal. These waves are too low frequency to affect sedimentation of dust to the midplane, but may have significance for the gravitational stability of the resulting midplane dust layers.« less

    In 1987 there was an unexplained increase in severe streptococcal diseases in Norway and other western countries. In Norway this increase was not accompanied by a corresponding increase in acute rheumatic fever. This study investigated the occurrence of scarlet fever and acute rheumatic fever in a rural district (approximately 15,000 inhabitants) of western Norway during the years 1862-1884. Four epidemics of severe scarlet fever occurred during this period. The local doctor treated 1,155 patients (96% children), of whom 154 (13.3%) died. Acute glomerulonephritis with subsequent kidney failure seems to have been a major cause of death. During the same period 76 patients (96% adults) were treated for acute rheumatic fever. These cases were not related to the severe epidemics of scarlet fever. It is probable that different, co-circulating strains of streptococci caused the infections, which were followed by glomerulonephritis and rheumatic fever. It is possible that rheumatic fever was caused by the strain that induced the more benign "Angina tonsillaris".

    In view of the fact that African swine fever (ASF) was recently introduced into the wild boar population of the European Union and that classical swine fever (CSF) keeps reoccurring, targeted surveillance is of utmost importance for early detection. Introduction of both diseases is usually accompanied by an increased occurrence of animals found dead. Thus, fallen wild boar are the main target for passive surveillance. However, encouraging reporting by hunters and sampling of these animals is difficult. Partly, these problems could be solved by providing a pragmatic sampling approach. For this reason, we assessed the applicability of three different dry/semi-dry blood swabs, namely a cotton swab, a flocked swab, and a forensic livestock swab, for molecular swine fever diagnosis. After nucleic acid extraction using manual and automated systems, routine quantitative real-time polymerase chain reactions (qPCR) were carried out. Results obtained from swabs or their fragments were compared to results generated from EDTA blood. It was shown that reliable detection of both pathogens was possible by qPCR. Shifts in genome copy numbers were observed, but they did not change the qualitative results. In general, all swabs were suitable, but the forensic swab showed slight advantages, especially in terms of cutting and further storage. Robustness of the method was confirmed by the fact that different extraction methods and protocols as well as storage at room temperature did not have an influence on the final outcome. Taken together, swab samples could be recommended as a pragmatic approach to sample fallen wild boar. Copyright © 2014 Elsevier B.V. All rights reserved.

  10. Self-Interaction Chromatography of mAbs: Accurate Measurement of Dead Volumes.

    Measurement of the second virial coefficient B22 for proteins using self-interaction chromatography (SIC) is becoming an increasingly important technique for studying their solution behaviour. In common with all physicochemical chromatographic methods, measuring the dead volume of the SIC packed column is crucial for accurate retention data; this paper examines best practise for dead volume determination. SIC type experiments using catalase, BSA, lysozyme and a mAb as model systems are reported, as well as a number of dead column measurements. It was observed that lysozyme and mAb interacted specifically with Toyopearl AF-Formyl dead columns depending upon pH and [NaCl], invalidating their dead volume usage. Toyopearl AF-Amino packed dead columns showed no such problems and acted as suitable dead columns without any solution condition dependency. Dead volume determinations using dextran MW standards with protein immobilised SIC columns provided dead volume estimates close to those obtained using Toyopearl AF-Amino dead columns. It is concluded that specific interactions between proteins, including mAbs, and select SIC support phases can compromise the use of some standard approaches for estimating the dead volume of SIC columns. Two other methods were shown to provide good estimates for the dead volume.

    Relatively high counting rates were registered in a proton inelastic scattering experiment on 16O and 28Si using HPGe detectors which was performed at the Tandem facility of IFIN-HH, Bucharest. In consequence, dead time corrections were needed in order to determine the absolute γ-production cross sections. Considering that the real counting rate follows a Poisson distribution, the dead time correction procedure is reformulated in statistical terms. The arriving time interval between the incoming events (Δt) obeys an exponential distribution with a single parameter - the average of the associated Poisson distribution. We use this mathematical connection to calculate and implement the dead time corrections for the counting rates of the mentioned experiment. Also, exploiting an idea introduced by Pommé et al., we describe a consistent method for calculating the dead time correction which completely eludes the complicated problem of measuring the dead time of a given detection system. Several comparisons are made between the corrections implemented through this method and by using standard (phenomenological) dead time models and we show how these results were used for correcting our experimental cross sections.

    The ICDP funded Dead Sea Deep Drilling Project (DSDDP) recovered the longest and most complete paleo-environmental record in the Middle East, drilling holes in a deep and a shallow site extending to ~450 meters. The Dead Sea expands during the glacials and contracts during interglacials, and the sediments are an archive of the evolving climatic conditions. During glacials the sediments comprise intervals of marl (aragonite, gypsum and detritus) and during interglacials they are salts and marls. We estimate that the deep site core spans ~200 kyr (to early MIS 7). A dramatic discovery is a ~40 cm interval of rounded pebbles at ~235 m below the lake floor, the only clean pebbly unit in the entire core. It appears to be a beach layer, near the deepest part of the Dead Sea, lying above ~35 meters of mainly salt. If it is a beach layer, it implies an almost complete dry-down of the paleo-Dead Sea. The pebble layer lies within the last interglacial interval. Our initial attempt to estimate the age of the possible dry down shows an intriguing correlation between the salt-mud stratigraphy of the Dead Sea core and the oxygen isotope record of Soreq Cave, whereby excursions to light oxygen in the speleothems correspond to periods of salt deposition. Through this comparison, we estimate that the dry down occurred during MIS 5e. The occurrence of ~35 meters of mainly salt along with the pebble layer demonstrates a severe dry interval during MIS 5. This observation has implications for the Middle East today, where the Dead Sea level is dropping as all the countries in the area use the runoff. GCM models indicate a more arid future in the region. The core shows that the runoff nearly stopped during a past warm period without human intervention.

  13. Dead cell phagocytosis and innate immune checkpoint

    2017-01-01

    The human body loses several billions of cells daily. When cells die in vivo, the corpse of each dead cell is immediately cleared. Specifically, dead cells are efficiently recognized and cleared by multiple types of neighboring phagocytes. Early research on cell death focused more on molecular mechanisms of cell death regulation while the cellular corpses were merely considered cellular debris. However, it has come to light that various biological stimuli following cell death are important for immune regulation. Clearance of normal dead cells occurs silently in immune tolerance. Exogenous or mutated antigens of malignant or infected cells can initiate adaptive immunity, thereby inducing immunogenicity by adjuvant signals. Several pathogens and cancer cells have strategies to limit the adjuvant signals and escape immune surveillance. In this review, we present an overview of the mechanisms of dead cell clearance and its immune regulations. PMID:28768566

    Q fever is a worldwide zoonosis with many acute and chronic manifestations caused by the pathogen Coxiella burnetii. Farm animals and pets are the main reservoirs of infection, and transmission to human beings is mainly accomplished through inhalation of contaminated aerosols. Persons at greatest risk are those in contact with farm animals and include farmers, abattoir workers, and veterinarians. The organs most commonly affected during Q fever are the heart, the arteries, the bones and the liver. The most common clinical presentation is an influenza-like illness with varying degrees of pneumonia and hepatitis. Although acute disease is usually self-limiting, people do occasionally die from this condition. Endocarditis is the most serious and most frequent clinical presentation of chronic Q fever. Vascular infection is the second most frequent presentation of Q fever. The diagnosis of Q fever is based on a significant increase in serum antibody titers. The treatment is effective and well tolerated, but must be adapted to the acute or chronic pattern with the tetracyclines to be considered the mainstay of antibiotic therapy. For the treatment of Q fever during pregnancy the use of long-term cotrimoxazole therapy is proposed. PMID:23113081

    Fever is one of the most common reasons for the emergency department presentation of immunocompromised patients. Their differential diagnosis can be broad and includes rare or unexpected pathogens. Certain infectious causes of fever portend true emergencies; if they are not managed appropriately, rapid progression and death may ensue. This article reviews the diagnosis and management of fevers in patients immunocompromised by human immunodeficiency virus/AIDS, solid-organ and hematopoietic transplants, chemotherapy-induced neutropenia, and tumor necrosis factor-α inhibitors. Prompt recognition of the type of immunosuppression and delineation of possible causes of fever are critical for management of these complex patients. Copyright © 2013 Elsevier Inc.

    The definition of fever is flexible and depends on the clinical context. Fever is frequently observed in patients with cancer. Infectious and noninfectious causes of fever in patients with various oncological and hematological malignancies and the usefulness of biomarkers are discussed. To treat patients in a timely manner and to minimize morbidity and mortality, it is paramount that health care professionals determine the cause of fever. The usefulness of biomarkers in febrile patients with cancer continues to be controversial. Fever is frequently seen in patients with cancer and can be associated with a variety of infectious and noninfectious causes. The utility of acute-phase reactants, such as erythrocyte sedimentation rate, C-reactive protein, and procalcitonin, along with a nonsteroidal anti-inflammatory drug challenge should be further evaluated as adjunct tools for the workup of fever in patients with cancer.

    This study attempted to find the incidence of scarlet fever in the Oxford region, including the proportion of patients from whom Streptococcus pyogenes could be isolated. General practitioners collected throat swabs from patients with suspected scarlet fever. The swabs were examined for viral and bacterial pathogens. Children admitted to hospital were used as controls. Twenty-five of 105 patients with suspected scarlet fever grew Str. pyogenes; M type 4 was the commonest type. The clinical diagnosis of scarlet fever was not always confirmed by throat culture. The annual incidence of scarlet fever was estimated to be 0.3 cases per 1000 per year. PMID:6358344

  19. Do the 'brain dead' merely appear to be alive?

    2017-11-01

    The established view regarding 'brain death' in medicine and medical ethics is that patients determined to be dead by neurological criteria are dead in terms of a biological conception of death, not a philosophical conception of personhood, a social construction or a legal fiction. Although such individuals show apparent signs of being alive, in reality they are (biologically) dead, though this reality is masked by the intervention of medical technology. In this article, we argue that an appeal to the distinction between appearance and reality fails in defending the view that the 'brain dead' are dead. Specifically, this view relies on an inaccurate and overly simplistic account of the role of medical technology in the physiology of a 'brain dead' patient. We conclude by offering an explanation of why the conventional view on 'brain death', though mistaken, continues to be endorsed in light of its connection to organ transplantation and the dead donor rule. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

    Mixed maerl beds (corralline red algae) comprise dead thalli with varying amounts of live maerl fragments, but previously it was not known whether the presence of the live maerl increases the ecosystem service 'habitat provision' of the dead maerl for the associated epibenthos. A 'flying array' towed sled with high definition video was used to film transects of the epibenthos in dead maerl and mixed maerl beds in two locations to the north and south of the English Channel (Falmouth and Jersey). Mixed maerl beds supported greater number of taxa and abundance than dead beds in Falmouth, while in Jersey, mixed and dead beds supported similar number of taxa and dead beds had a greater abundance of epifauna. Scallops tended to be more abundant on mixed beds than dead beds. Tube worms were more abundant on mixed beds in Falmouth and dead beds in Jersey. An increasing percentage occurrence of live maerl thalli correlated with increasing number of taxa in Falmouth but not Jersey. It was concluded that while live thalli can increase the functional role of dead maerl beds for the epibenthos, this is dependent on location and response variable. As a result of this work, maerl habitat in SE Jersey has been protected from towed demersal fishing gear.

    The Brisbane Supreme Court has denied an Australian woman's request to harvest and freeze her dead fiancé's sperm for future impregnation. After she was denied access to the sperm, the woman learnt that her fiancé may have been a sperm donor and she began checking to find out if his sperm was still available. Given what we know, there is a good ethical argument that the woman should have access to the sperm and should be allowed to have her dead fiancé's child. Another aspect of this case is that it illustrates the way in which ethics, law, and personal opinion can differ.

    Summary In Escherichia coli, activity of the global regulatory RNA binding protein CsrA is antagonized by two noncoding sRNAs, CsrB and CsrC, which sequester it away from its lower affinity mRNA targets. Transcription of csrB/C requires the BarA-UvrY two component signal transduction system, which responds to short chain carboxylates. We show that two DEAD-box RNA helicases, DeaD and SrmB, activate csrB/C expression by different pathways. DeaD facilitates uvrY translation by counteracting the inhibitory effect of long distance basepairing between the uvrY mRNA leader and coding region, while SrmB does not affect UvrY or UvrY-phosphate levels. Contrary to the prevailing notion that these helicases act primarily at low temperatures, DeaD and SrmB activated csrB expression over a wide temperature range. High-throughput sequencing of RNA isolated by crosslinking immunoprecipitation (HITS-CLIP) revealed in vivo interactions of DeaD with 39 mRNAs, including those of uvrY and 9 other regulatory genes. Studies on the expression of several of the identified genes revealed regulatory effects of DeaD in all cases and diverse temperature response patterns. Our findings uncover an expanded regulatory role for DeaD, which is mediated through novel mRNA targets, important global regulators and under physiological conditions that were considered to be incompatible with its function.

    An improved circuit is provided for application to a radiation survey meter that uses a detector that is subject to dead time. The circuit compensates for dead time over a wide range of count rates by producing a dead-time pulse for each detected event, a live-time pulse that spans the interval between dead-time pulses, and circuits that average the value of these pulses over time. The logarithm of each of these values is obtained and the logarithms are subtracted to provide a signal that is proportional to a count rate that is corrected for the effects of dead time. The circuit produces a meter indication and is also capable of producing an audible indication of detected events.

    In recent years, political figures begin to utilize social media as one of alternative to engage in communication with their supporters. Publics referred to Jokowi, one of the candidates in Indonesia presidential election in 2014, as the first politician in Indonesia to truly understand the power of social media. Social media is very important in shaping public opinion. In this paper, effect of social media on the Jokowi-fever model in a closed population will be discussed. Supporter population is divided into three class sub-population, i.e susceptible supporters, Jokowi infected supporters, and recovered supporters. For case no positive media, there are two equilibrium points; the Jokowi-fever free equilibrium point in which it locally stable if basic reproductive ratio less than one and the Jokowi-fever endemic equilibrium point in which it locally stable if basic reproductive ratio greater than one. For case no negative media, there is only the Jokowi-fever endemic equilibrium point in which it locally stable if the condition is satisfied. Generally, for case positive media proportion is positive, there is no Jokowi-fever free equilibrium point. The numerical result shows that social media gives significantly effect on Jokowi-fever model, a sharp increase or a sharp decrease in the number of Jokowi infected supporters. It is also shown that the boredom rate is one of the sensitive parameters in the Jokowi-fever model; it affects the number of Jokowi infected supporters.

    A medical investigation was carried out in April 2001 into an outbreak of a mysterious haemorrhagic disease and deaths in the remote picturesque Strickland River area of Papua New Guinea (PNG). The area is in part of the Southern Highlands and West Sepik Provinces and situated downstream from the Porgera Joint Venture gold mine. 9 villages were visited and 140 persons, consisting of immediate blood relatives of the deceased (cases) and others in the village picked at random (controls), were physically examined. Specimens of blood, urine and faeces were collected from each person for laboratory tests in PNG and Australia. Positive sera for dengue (15%) and Japanese encephalitis (JE) (6%) were identified. Surprisingly, a number of the sera were positive for scrub typhus (Orientia tsutsugamushi) (28%) and spotted fever (Rickettsia australis) (11%). The last reported cases of scrub typhus in PNG were during World War Two among the allied troops. This is the first time spotted fever (R. australis) has been reported in PNG. These conditions may have been the cause of the deaths described by the villagers. However, there were significantly more dengue-positive results among relatives of the deceased than non-relatives though no such difference was found with rickettsial infections: haemorrhagic dengue fever is thus the most likely cause of this recurring outbreak. Mining did not appear to be a direct causal factor for the deaths in the area.

    Acute septicemic spirochetosis was diagnosed in an adult male northern spotted owl (Strix occidentalis caurina) found dead in Kittitas County, Washington, USA. Gross necropsy findings included marked enlargement of the liver and spleen and serofibrinous deposits on the serous membranes lining the body cavities and the pericardial and perihepatic sacs. Microscopic observations included macrophage infiltration in the liver and spleen with mild thrombosis and multifocal necrosis, as well as hemorrhage and acute inflammation in the choroid plexus of the brain. No viruses or pathogenic bacteria were isolated from brain, liver, or spleen, and no parasites were found in blood smears or impression smears of the liver. Chlamydial culture attempts were unsuccessful and no chlamydial antibodies were detected in serum. In silver-stained microscopic sections and by transmission electron microscopy of liver, numerous long, thin, spiral-shaped bacteria were seen in the liver, spleen, cerebral ventricles, and within blood vessels in many organs. The organism was identified as a member of the Borrelia genus by sequence analysis of the PCR-amplified 16S rRNA gene. The most closely related species is B. hermsii, an agent of relapsing fever in humans in the western United States. This is the first report of a relapsing fever-related Borrelia in a wild bird.

  11. STUDIES ON TUBERCULIN FEVER

    Evidence has been presented that the fever elicited by intravenous administration of old tuberculin (O.T.) in BCG-infected rabbits is a specific property of this hypersensitivity system and is probably not due to contamination of tuberculin with bacterial endotoxins. Daily injections of O.T. in sensitized animals resulted in a rapid tolerance to its pyrogenic effect. Tuberculin tolerance can be differentiated from that occurring with endotoxins and was invariably associated with the development of a negative skin test. The mechanism of this tolerance would thus appear to be desensitization. A circulating pyrogen found during tuberculin fever was indistinguishable in its biologic effects from endogenous pyrogens obtained in several other types of experimental fever. This material produced fevers in normal recipients and therefore may be clearly differentiated from O.T. itself which was pyrogenic only to sensitized animals. Since the titer of serum pyrogen was directly proportional to the degree of fever induced by injection of O.T. in the donor animals, a causal relation is suggested. On the basis of these findings, it is postulated that tuberculin fever is due to a circulating endogenous pyrogen released by a specific action of O.T. on sensitized cells of the host. PMID:13641561

Forty-eight hours after admission, the presence of subconjunctival haemorrhage, malena, and jaundice raised the possibility of a different aetiology, the two most likely differentials being dengue and typhus. Finally, a co-infection of typhoid and typhus was discovered. This uncommon clinical scenario should be taken into account in the management of patients with high fever on admission being treated as a case of typhoid fever.

    Yellow fever, the original viral haemorrhagic fever, was one of the most feared lethal diseases before the development of an effective vaccine. Today the disease still affects as many as 200,000 persons annually in tropical regions of Africa and South America, and poses a significant hazard to unvaccinated travellers to these areas. Yellow fever is transmitted in a cycle involving monkeys and mosquitoes, but human beings can also serve as the viraemic host for mosquito infection. Recent increases in the density and distribution of the urban mosquito vector, Aedes aegypti, as well as the rise in air travel increase the risk of introduction and spread of yellow fever to North and Central America, the Caribbean and Asia. Here I review the clinical features of the disease, its pathogenesis and pathophysiology. The disease mechanisms are poorly understood and have not been the subject of modern clinical research. Since there is no specific treatment, and management of patients with the disease is extremely problematic, the emphasis is on preventative vaccination. As a zoonosis, yellow fever cannot be eradicated, but reduction of the human disease burden is achievable through routine childhood vaccination in endemic countries, with a low cost for the benefits obtained. The biological characteristics, safety, and efficacy of live attenuated, yellow fever 17D vaccine are reviewed. New applications of yellow fever 17D virus as a vector for foreign genes hold considerable promise as a means of developing new vaccines against other viruses, and possibly against cancers.

    Fever is common in patients with intracerebral hemorrhage (ICH). We sought to identify predictors of fever in patients hospitalized with ICH, and compare infectious fever with noninfectious fever. A retrospective review on consecutive spontaneous ICH patients from April 2009 to March 2010 was performed. Fever was defined as temperature 100.9°F or higher and attributed to infectious versus noninfectious etiology, based upon the National Healthcare Safety Network criteria. Univariate analysis and multivariable logistic regression model were used to determine factors associated with fever and with infection. Among the 351 ICH patients, 136 (39%) developed fever. Factors associated with fever included mean ICH volume, intraventricular hemorrhage (IVH), external ventricular drain (EVD) placement or surgical evacuation, positive microbial cultures, longer length of stay (LOS), and higher in-hospital mortality. Among patients with fever, 96 (71%) were noninfectious and 40 (29%) were infectious. Infectious fever was associated with higher LOS. Noninfectious fever was associated with higher in-hospital mortality. In multivariable analysis, ICH volume (OR = 1.01, P = .04), IVH (OR = 2.0, P = .03), EVD (OR = 3.7, P < .0001), and surgical evacuation (OR = 6.78, P < .0001) were significant predictors of fever. Infectious fever (OR = 5.26, P = .004), EVD (OR = 4.86, P = .01), and surgical evacuation (OR = 4.77, P = .04) correlated with prolonged LOS when dichotomized using a median of 15 days. Fever is common in ICH patients and is not associated with a clear infectious etiology in the majority of patients. Patients with noninfectious fever have higher in-hospital mortality, but survivors have shorter LOS. Further studies are warranted to better understand fevers in ICH.

  16. Localizing chronic Q fever: a challenging query

    PubMed Central

    2013-01-01

    Background Chronic Q fever usually presents as endocarditis or endovascular infection. We investigated whether 18F-FDG PET/CT and echocardiography were able to detect the localization of infection. Also, the utility of the modified Duke criteria was assessed. Methods Fifty-two patients, who had an IgG titre of ≥ 1024 against C. burnetii phase I ≥ 3 months after primary infection or a positive PCR ≥ 1 month after primary infection, were retrospectively included. Data on serology, the results of all imaging studies, possible risk factors for developing proven chronic Q fever and clinical outcome were recorded. Results According to the Dutch consensus on Q fever diagnostics, 18 patients had proven chronic Q fever, 14 probable chronic Q fever, and 20 possible chronic Q fever. Of the patients with proven chronic Q fever, 22% were diagnosed with endocarditis, 17% with an infected vascular prosthesis, and 39% with a mycotic aneurysm. 56% of patients with proven chronic Q fever did not recall an episode of acute Q fever. Ten out of 13 18F-FDG PET/CT-scans in patients with proven chronic Q fever localized the infection. TTE and TEE were helpful in only 6% and 50% of patients, respectively. Conclusions If chronic Q fever is diagnosed, 18F-FDG PET/CT is a helpful imaging technique for localization of vascular infections due to chronic Q fever. Patients with proven chronic Q fever were diagnosed significantly more often with mycotic aneurysms than in previous case series. Definite endocarditis due to chronic Q fever was less frequently diagnosed in the current study. Chronic Q fever often occurs in patients without a known episode of acute Q fever, so clinical suspicion should remain high, especially in endemic regions. PMID:24004470

    The objective of the multidisciplinary expert Consensus Panel on Research with the Recently Dead (CPRRD) was to craft ethics guidelines for research with the recently dead. The CPRRD recommends that research with the recently dead: (i) receive scientific and ethical review and oversight; (ii) involve the community of potential research subjects; (iii) be coordinated with organ procurement organizations; (iv) not conflict with organ donation or required autopsy; (v) use procedures respectful of the dead; (vi) be restricted to one procedure per day; (vii) preferably be authorized by first-person consent, though both general advance research directives and surrogate consent are acceptable; (viii) protect confidentiality; (ix) not impose costs on subjects' estates or next of kin and not involve payment; (x) clearly explain ultimate disposition of the body.

  4. Are Brain Dead Individuals Dead? Grounds for Reasonable Doubt

    PubMed Central

    Brugger, E. Christian

    2016-01-01

    According to the biological definition of death, a human body that has not lost the capacity to holistically organize itself is the body of a living human individual. Reasonable doubt against the conclusion that it has lost the capacity exists when the body appears to express it and no evidence to the contrary is sufficient to rule out reasonable doubt against the conclusion that the apparent expression is a true expression (i.e., when the conclusion that what appears to be holistic organization is in fact holistic organization remains a reasonable explanatory hypothesis in light of the best evidence to the contrary). This essay argues that the evidence and arguments against the conclusion that the signs of complex bodily integration exhibited in ventilated brain dead bodies are true expressions of somatic integration are unpersuasive; that is, they are not adequate to exclude reasonable doubt against the conclusion that BD bodies are dead. Since we should not treat as corpses what for all we know might be living human beings, it follows that we have an obligation to treat BD individuals as if they were living human beings.

    Objective Pulmonary dead-space fraction is one of few lung-specific independent predictors of mortality from acute respiratory distress syndrome (ARDS). However, it is not measured routinely in clinical trials and thus altogether ignored in secondary analyses that shape future research directions and clinical practice. This study sought to validate an estimate of dead-space fraction for use in secondary analyses of clinical trials. Design Analysis of patient-level data pooled from ARDS clinical trials. Four approaches to estimate dead-space fraction were evaluated: three required estimating metabolic rate; one estimated dead-space fraction directly. Setting U.S. academic teaching hospitals. Patients Data from 210 patients across three clinical trials were used to compare performance of estimating equations with measured dead-space fraction. A second cohort of 3,135 patients from six clinical trials without measured dead-space fraction was used to confirm whether estimates independently predicted mortality. Interventions None. Measurements and Main Results Dead-space fraction estimated using the unadjusted Harris-Benedict equation for energy expenditure was unbiased (mean ± SD Harris-Benedict 0.59 ± 0.13; measured 0.60 ± 0.12). This estimate predicted measured dead-space fraction to within ± 0.10 in 70% of patients and ± 0.20 in 95% of patients. Measured dead-space fraction independently predicted mortality (OR 1.36 per 0.05 increase in dead-space fraction, 95% CI 1.10–1.68; p < .01). The Harris-Benedict estimate closely approximated this association with mortality in the same cohort (OR 1.55, 95% CI 1.21–1.98; p < .01) and remained independently predictive of death in the larger ARDSNet cohort. Other estimates predicted measured dead-space fraction or its association with mortality less well. Conclusions Dead-space fraction should be measured in future ARDS clinical trials to facilitate incorporation into secondary analyses. For analyses where dead

    Thirteen pregnant goats were inoculated intravenously with the ALD strain of virulent swine fever (SF) virus on Days 64-84 of gestation. Dams showed transient and mild viremia, and produced high serum neutralizing (SN) antibody after inoculation. Six inoculated dams were reared until parturition occurred and bore six apparently normal, one apparently normal but dead, one mummified and three edematous kids. Neutralizing antibody was demonstrated in the pre-colostral sera obtained from all normal kids, but no SF virus was isolated from any of them. The other seven dams were killed on post-inoculation days (PID) 5-61, and fetuses, placenta and amnion were tested for the virus and SN antibody. All fetuses of five dams examined within PID 40 were positive for SF virus, but negative for SN antibody. SF virus was also isolated from one of three fetuses examined on PID 61. Conversely, the other two fetuses examined on PID 61 were negative for SF virus, but positive for SN antibody. Furthermore, SF virus was isolated from the placenta and amnion of all the dams.

    Scarlet fever, an infection caused by toxin-producing strains of Streptococcus pyogenes, was associated with high levels of morbidity and mortality when epidemics were common in the 18 th and 19 th centuries throughout Europe and the USA. 1 Although this disease nearly disappeared during the 20 th century, several countries, including the UK, have recently experienced a re-emergence of scarlet fever. 1-3 However, the reason for these new outbreaks remains unclear. 1,4 Despite a general move to reduce the use of antibiotics for many mild self-limiting infections (e.g. tonsillitis, sinusitis), national guidance recommends treating people with scarlet fever with antibiotics regardless of severity of illness to speed recovery, to reduce the length of time the infection is contagious and to reduce the risk of complications. 5,6 Here, we discuss the management of scarlet fever in the UK.

    Fever can reduce mortality in infected animals. Yet, despite its fitness-enhancing qualities, fever often varies among animals. We used several approaches to examine this variation in insects. Texas field crickets (Gryllus texensis) exhibited a modest fever (1 °C increase in preferred body temperature, T pref) after injection of prostaglandin, which putatively mediates fever in both vertebrates and invertebrates, but they did not exhibit fever during chronic exposure to heat-killed bacteria. Further, chronic food limitation and mating status did not affect T pref or the expression of behavioural fever, suggesting limited context dependency of fever in G. texensis. Our meta-analysis of behavioural fever studies indicated that behavioural fever occurs in many insects, but it is not ubiquitous. Thus, both empirical and meta-analytical results suggest that the fever response in insects 'is widespread, although certainly not inevitable' (Moore 2002). We highlight the need for future work focusing on standardizing an experimental protocol to measure behavioural fever, understanding the specific mechanism(s) underlying fever in insects, and examining whether ecological or physiological costs often outweigh the benefits of fever and can explain the sporadic nature of fever in insects.

    Typhoid fever (enteric fever) remains a burden in developing countries and a major health problem in Southern and Southeastern Asia. Salmonella typhi (S. typhi), the causative agent of typhoid fever, is a gram-negative, motile, rod-shaped, facultative anaerobe and solely a human pathogen with no animal reservoir. Infection of S. typhi can cause fever, abdominal pain and many worsenonspecific symptoms, including gastrointestinal symptoms suchas nausea, vomiting, constipation, and diarrhea. Chloramphenicol, ampicillin,and cotrimoxazole were the first-recommended antibiotics in treating typhoid fever. In the last two decades though, these three traditional drugs started to show resistance and developed multidrug resistance (MDR) S. typhi strains. In many parts of the world, the changing modes ofpresentation and the development of MDR have made typhoid fever increasingly difficult to treat.The use of first-line antimicrobials had been recommended to be fluoroquinolone as a replacement. However, this wassoonfollowedbyreportsof isolates ofS. typhi showing resistancetofluoroquinolones as well. These antimicrobial resistance problems in typhoid fever have been an alarming situation ever since and need to be taken seriously or else typhoid fever will no longer be taken care completely by administering antibiotics.

    Context Fever is an important sign of inflammation recognized by health care practitioners and family caregivers. However, few empirical data obtained directly from patients exist to support many of the long-standing assumptions about the symptoms of fever. Many of the literature-cited symptoms, including chills, diaphoresis, and malaise, have limited scientific bases, yet they often represent a major justification for antipyretic administration. Objectives To describe the patient experience of fever symptoms for the preliminary development of a fever assessment questionnaire. Methods Qualitative interviews were conducted with 28 inpatients, the majority (86%) with cancer diagnoses, who had a recorded temperature of ≥38°C within approximately 12 hours before the interview. A semi-structured interview guide was used to elicit patient fever experiences. Thematic analyses were conducted by three independent research team members, and the data were verified through two rounds of consensus building. Results Eleven themes emerged. The participants reported experiences of feeling cold, weakness, warmth, sweating, nonspecific bodily sensations, gastrointestinal symptoms, headaches, emotional changes, achiness, respiratory symptoms, and vivid dreams/hallucinations. Conclusion Our data not only confirm long-standing symptoms of fever but also suggest new symptoms and a level of variability and complexity not captured by the existing fever literature. Greater knowledge of patients’ fever experiences will guide more accurate assessment of symptoms associated with fever and the impact of antipyretic treatments on patient symptoms in this common condition. Results from this study are contributing to the content validity of a future instrument that will evaluate patient outcomes related to fever interventions. PMID:23742739

  18. World War I psychoneuroses: hysteria goes to war.

    PubMed

    Tatu, Laurent; Bogousslavsky, Julien

    2014-01-01

    During the First World War, military physicians from the belligerent countries were faced with soldiers suffering from psychotrauma with often unheard of clinical signs, such as camptocormia. These varied clinical presentations took the form of abnormal movements, deaf-mutism, mental confusion, and delusional disorders. In Anglo-Saxon countries, the term 'shell shock' was used to define these disorders. The debate on whether the war was responsible for these disorders divided mobilized neuropsychiatrists. In psychological theories, war is seen as the principal causal factor. In hystero-pithiatism, developed by Joseph Babinski (1857-1932), trauma was not directly caused by the war. It was rather due to the unwillingness of the soldier to take part in the war. Permanent suspicion of malingering resulted in the establishment of a wide range of medical experiments. Many doctors used aggressive treatment methods to force the soldiers exhibiting war neuroses to return to the front as quickly as possible. Medicomilitary collusion ensued. Electrotherapy became the basis of repressive psychotherapy, such as 'torpillage', which was developed by Clovis Vincent (1879-1947), or psychofaradism, which was established by Gustave Roussy (1874-1948). Some soldiers refused such treatments, considering them a form of torture, and were brought before courts-martial. Famous cases, such as that of Baptiste Deschamps (1881-1953), raised the question of the rights of the wounded. Soldiers suffering from psychotrauma, ignored and regarded as malingerers or deserters, were sentenced to death by the courts-martial. Trials of soldiers or doctors were also held in Germany and Austria. After the war, psychoneurotics long haunted asylums and rehabilitation centers. Abuses related to the treatment of the Great War psychoneuroses nevertheless significantly changed medical concepts, leading to the modern definition of 'posttraumatic stress disorder'.

  19. Setting Dead at Zero: Applying Scale Properties to the QALY Model.

    2018-04-01

    Scaling severe states can be a difficult task. First, the method of measurement affects whether a health state is considered better or worse than dead. Second, in discrete choice experiments, different models to anchor health states on 0 (dead) and 1 (perfect health) produce varying amounts of health states worse than dead. Within the context of the quality-adjusted life-year (QALY) model, this article provides insight into the value assigned to dead and its consequences for decision making. Our research questions are 1) what are the arguments set forth to assign dead the number 0 on the health-utility scale? And 2) what are the effects of the position of dead on the health-utility scale on decision making? A literature review was conducted to explore the arguments set forth to assign dead a value of 0 in the QALY model. In addition, scale properties and transformations were considered. The review uncovered several practical and theoretical considerations for setting dead at 0. In the QALY model, indifference between 2 health episodes is not preserved under changes of the origin of the duration scale. Ratio scale properties are needed for the duration scale to preserve indifferences. In combination with preferences and zero conditions for duration and health, it follows that dead should have a value of 0. The health-utility and duration scales have ratio scale properties, and dead should be assigned the number 0. Furthermore, the position of dead should be carefully established, because it determines how life-saving and life-improving values are weighed in cost-utility analysis.

    A total of 100 consecutive episodes of fever of 101° F (38·3°C) or above in 56 neutropenic patients have been investigated. All the patients had either acute leukaemia or aplastic anaemia. A cause for the fever was found in 68 of these episodes, in 87% of which it was due to infection. The commonest single finding was septicaemia (30 episodes). Only two episodes of fever could be ascribed solely to the underlying malignant disease. Infection should be assumed to be present and the cause of fever in neutropenic patients until proved otherwise. PMID:4843653

  1. The dead donor rule: can it withstand critical scrutiny?

    PubMed

    Miller, Franklin G; Truog, Robert D; Brock, Dan W

    2010-06-01

    Transplantation of vital organs has been premised ethically and legally on "the dead donor rule" (DDR)-the requirement that donors are determined to be dead before these organs are procured. Nevertheless, scholars have argued cogently that donors of vital organs, including those diagnosed as "brain dead" and those declared dead according to cardiopulmonary criteria, are not in fact dead at the time that vital organs are being procured. In this article, we challenge the normative rationale for the DDR by rejecting the underlying premise that it is necessarily wrong for physicians to cause the death of patients and the claim that abandoning this rule would exploit vulnerable patients. We contend that it is ethical to procure vital organs from living patients sustained on life support prior to treatment withdrawal, provided that there is valid consent for both withdrawing treatment and organ donation. However, the conservatism of medical ethics and practical concerns make it doubtful that the DDR will be abandoned in the near future. This leaves the current practice of organ transplantation based on the "moral fiction" that donors are dead when vital organs are procured.

    Adverse reactions to mesalamine, a treatment used to induce and maintain remission in inflammatory bowel diseases, particularly ulcerative colitis, have been described in the literature as case reports. This case illustrates an unusual adverse reaction. Our patient developed an isolated fever of unexplained etiology, which was found to be related to mesalamine treatment. A 22-year-old patient diagnosed with ulcerative colitis developed a fever with rigors and anorexia 10 d after starting oral mesalamine while his colitis was clinically resolving. Testing revealed no infection. A mesalamine-induced fever was considered, and treatment was stopped, which led to spontaneous resolution of the fever. The diagnosis was confirmed by reintroducing the mesalamine. One year later, this side effect was noticed again in the same patient after he was administered topical mesalamine. This reaction to mesalamine seems to be idiosyncratic, and the mechanism that induces fever remains unclear. Fever encountered in the course of a mesalamine treatment in ulcerative colitis must be considered a mesalamine-induced fever when it cannot be explained by the disease activity, an associated extraintestinal manifestation, or an infectious etiology.

Additionally, this review aims at providing suggestions on how to deal with fever, and with the anxiety it causes. Bibliographic review using Medline database and previously selected manuscripts. Fever may cause both negative and positive outcomes, none of major consequence. Age group, fever magnitude and duration, shivering, appetite decrease or behavioral changes (toxemia), and other localizing symptoms should be investigated through the patient's medical history. Laboratory screening tests should include complete blood count, erythrocyte sedimentation rate, C-reactive protein, urinalysis (white cells count and gram stain of the sediment), and in some cases, lumbar puncture and blood culture. The treatment should include antipyretic medications and, occasionally, physical methods (cool baths, sponging) in order to reduce discomfort caused by the fever. Children with fever request both scientific expertise, as well as empathy from the pediatrician, so that they can receive individualized therapy.

Five observations of factitious fever are presented including 2 cases of thermometer manipulation in men aged 45 and 80. The latter patient is the oldest in whom such a case has been reported. In the first case the prolonged fever led to exploratory laparotomy with splenectomy followed by antilymphoma chemotherapy before the thermometer manipulation was discovered. This patient had previously been treated successfully for stage Ib Hodgkin lymphoma. In the other case hospitalization had lasted several weeks, and much antibiotic and steroid treatment had been administered, before the manipulation was suspected. A third case of thermometer manipulation was observed in a 57-year-old woman who had been presenting with factitious symptoms for over 10 years. Two other cases of factitious fever due to self-induced infections have been observed in two young women aged 23 and 27, both in paramedical professions. These self-induced infections led to polymicrobial bacteremia, exploratory laparotomy and hemicolectomy in one case, and to probable bacterial meningitis in the other. Certain aspects of these cases agree well with the diagnostic criteria of factitious fever described in the literature. We feel it is important to recognize this cause of febrile states, even if there is an apparent etiology, in order to avoid much vain investigation and prolonged hospitalization.

    Viral hemorrhagic fevers (VHFs) typically manifest as rapidly progressing acute febrile syndromes with profound hemorrhagic manifestations and very high fatality rates. Lassa fever, an acute hemorrhagic fever characterized by fever, muscle aches, sore throat, nausea, vomiting, diarrhea and chest and abdominal pain. Rodents are important reservoirs of rodent-borne zoonosis worldwide. Transmission rodents to humans occur by aerosol spread, either from the genus Mastomys rodents' excreta (multimammate rat) or through the close contact with infected patients (nosocomial infection). Other rodents of the genera Rattus, Mus, Lemniscomys, and Praomys are incriminated rodents hosts. Now one may ask do the rodents' ectoparasites play a role in Lassa virus zoonotic transmission. This paper summarized the update knowledge on LHV; hopping it might be useful to the clinicians, nursing staff, laboratories' personals as well as those concerned zoonoses from rodents and rodent control.

  14. Extreme drying event in the Dead Sea basin during MIS5 from the ICDP Dead Sea Deep Drill Core

    The ICDP funded Dead Sea Deep Drilling Project (DSDDP) recovered the longest and most complete paleo-environmental record in the Middle East, drilling holes of ~450 and ~350 meters in length in deep (~300 m below the lake level) and shallow sites (~3 mbll) respectively. The Dead Sea expands during the glacials and contracts during interglacials, and the sediments comprise a geological archive of the evolving environmental conditions (e.g. rains, floods, dust-storms, droughts). Dead Sea sediments include inorganic aragonite, allowing for dating by U-series (e.g. Haase-Schramm et al. GCA 2004). The deep site cores were opened and described in June 2011. The cores are composed mainly of alternating intervals of marl (aragonite, gypsum and detritus) during glacials, and salts and marls during interglacials. From this stratigraphy we estimate that the deep site core spans ~200 kyr (to the boundary of MIS 6 and 7). A dramatic discovery is a ~40 cm thick interval of partly rounded pebbles at ~235 m below the lake floor. This is the only clean pebbly unit in the entire core. It appears to be a beach layer, near the deepest part of the Dead Sea, lying above ~35 meters of mainly salt. If it is a beach layer, it implies an almost complete dry-down of the paleo-Dead Sea. The pebble layer lies within the last interglacial interval. Our initial attempt to more precisely estimate the age of the possible dry down shows an intriguing correlation between the salt-mud stratigraphy of the Dead Sea core and the oxygen isotope record of Soreq Cave, whereby excursions to light oxygen in the speleothems correspond to periods of salt deposition. Through this comparison, we estimate that the possible dry down occurred during MIS 5e. The occurrence of ~35 meters of mainly salt along with the pebble layer demonstrates a severe dry interval during MIS 5. This observation has implications for the Middle East today, where the Dead Sea level is dropping as all the countries in the area use the

    Fever in the neurocritical care setting is common and has a negative impact on outcome of all disease types. Meta-analyses have demonstrated that fever at onset and in the acute setting after ischemic brain injury, intracerebral hemorrhage, and cardiac arrest has a negative impact on morbidity and mortality. Data support that the impact of fever is sustained for longer durations after subarachnoid hemorrhage and traumatic brain injury. Recent advances have made eliminating fever and maintaining normothermia feasible. However, there are no prospective randomized trials demonstrating the benefit of fever control in these patient populations, and important questions regarding indications and timing remain. The purpose of this review is to analyze the data surrounding the impact of fever across a range of neurologic injuries to better understand the optimal timing and duration of fever control. Prospective randomized trials are needed to determine whether the beneficial impact of secondary injury prevention is outweighed by the potential risks of prolonged fever control.

    Fever is one of the most common complaints in the emergency department (ED) and is more complex than generally appreciated. The broad differential diagnosis of fever includes numerous infectious and non-infectious etiologies. An essential skill in emergency medicine is recognizing the pitfalls in fever evaluation. This review provides an overview of the complaint of fever in the ED to assist the emergency physician with a structured approach to evaluation. Fever can be due to infectious or non-infectious etiology and results from the body's natural response to a pyrogen. Adjunctive testing including C-reactive protein, erythrocyte sedimentation rate, and procalcitonin has been evaluated in the literature, but these tests do not have the needed sensitivity and specificity to definitively rule in a bacterial cause of fever. Blood cultures should be obtained in septic shock or if the results will change clinical management. Fever may not be always present in true infection, especially in elderly and immunocompromised patients. Oral temperatures suffer from poor sensitivity to diagnose fever, and core temperatures should be utilized if concern for fever is present. Consideration of non-infectious causes of elevated temperature is needed based on the clinical situation. Any fever evaluation must rigorously maintain a broad differential to avoid pitfalls that can have patient care consequences. Fever is complex and due to a variety of etiologies. An understanding of the pathophysiology, causes, and assessment is important for emergency physicians. Published by Elsevier Inc.

    Although specific treatment is available for Lassa fever, early diagnosis is still difficult in most Nigerian primary and secondary health centers. This study was carried out to compare the case-fatality rates of Lassa fever and other medical diseases commonly seen in adult medical wards, to determine the community habits that make Lassa fever endemic in Edo Central District of Nigeria, with the aim of prescribing preventive measures for its control in Nigeria. The records of 908 inpatients in the adult medical wards of Irrua Specialist Teaching Hospital, Irrua and responses from respondents interviewed by trained interviewers on their knowledge, attitudes and practices pertaining to Lassa fever were used for this study. The case-fatality rate of Lassa fever in this center was 28%. Cultural factors and habits were found to favor endemicity of Lassa fever in Edo Central District of Nigeria. Preventive measures were prescribed for families and communities.

    1. Micro-injections of prostaglandin E1 (PGE1) into the anterior hypothalamus of the rabbit produced fever which was nearly immediate in onset. The prostaglandin sensitive region appears to be identical to that described as being fever sensitive to leucocytic pyrogen. 2. Micro-injections of PGE1 into the posterior hypothalamus and midbrain reticular formation of the rabbit did not produce fever. 3. The febrile response to PGE1 injected into the anterior hypothalamus was dose dependent over a range of 20-1000 ng. 4. Ambient temperature influenced the thermoregulatory mechanism by which PGE1 fever evolved. In the cold, PGE1 fever was due to increased heat production while during heat exposure both evaporative and dry heat losses were reduced without significant changes in heat production. Vasoconstriction, confined mainly to the ears, was effective in producing fever in standard room environments (24-25° C) along with a small increase in heat production. 5. The preoptic anterior hypothalamic area retained its thermosensitivity during PGE1 fever; heating this area attenuated, while cooling augmented the fever. 6. The results support the view that PGE1 is a mediator of pyrogen induced fever. ImagesFig. 2 PMID:4733481

    Fever and leukocytosis have many possible etiologies in injection drug users. We present a case of a 22-year-old woman with fever and leukocytosis that were presumed secondary to cotton fever, a rarely recognized complication of injection drug use, after an extensive workup. Cotton fever is a benign, self-limited febrile syndrome characterized by fevers, leukocytosis, myalgias, nausea and vomiting, occurring in injection drug users who filter their drug suspensions through cotton balls. While this syndrome is commonly recognized amongst the injection drug user population, there is a paucity of data in the medical literature. We review the case presentation and available literature related to cotton fever.

    1968-01-01

    When rabbits sensitized to human serum albumin (HSA) are challenged intravenously with specific antigen, fever develops and two transferable pyrogens can be demonstrated in the circulation. The first appears prior to the development of fever and has properties consistent with soluble antigen-antibody complexes. These have been shown to be pyrogenic when prepared in vitro and to produce a state of febrile tolerance when repeatedly administered. The second pyrogen, demonstrable during fever in donor rabbits, appears to be similar to endogenous pyrogen described in other experimental fevers. It is postulated that the formation of antigen-antibody complexes constitutes an important initial phase of the febrile reaction in this type of immune fever. PMID:4873023

    Children presenting with recurrent fever may represent a diagnostic challenge. After excluding the most common etiologies, which include the consecutive occurrence of independent uncomplicated infections, a wide range of possible causes are considered. This article summarizes infectious and noninfectious causes of recurrent fever in pediatric patients. We highlight that, when investigating recurrent fever, it is important to consider age at onset, family history, duration of febrile episodes, length of interval between episodes, associated symptoms and response to treatment. Additionally, information regarding travel history and exposure to animals is helpful, especially with regard to infections. With the exclusion of repeated independent uncomplicated infections, many infective causes of recurrent fever are relatively rare in Western countries; therefore, clinicians should be attuned to suggestive case history data. It is important to rule out the possibility of an infectious process or a malignancy, in particular, if steroid therapy is being considered. After excluding an infectious or neoplastic etiology, immune-mediated and autoinflammatory diseases should be taken into consideration. Together with case history data, a careful physical exam during and between febrile episodes may give useful clues and guide laboratory investigations. However, despite a thorough evaluation, a recurrent fever may remain unexplained. A watchful follow-up is thus mandatory because new signs and symptoms may appear over time. PMID:27023528

    Brink, Uri ten

    I cannot think of a subject more befitting the description of interdisciplinary research with societal relevance than the study of the Dead Sea, a terminal lake of the Jordan River in Israel and Jordan. The scientific study of the Dead Sea is intimately connected with politics, religion, archeology, economic development, tourism, and environmental change.The Dead Sea is a relatively closed geologic and limnologic system with drastic physical changes often occurring on human timescales and with a long human history to observe these changes. Research in this unique area covers diverse aspects such as active subsidence and deformation along strike-slip faults; vertical stratification and stability of the water column; physical properties of extremely saline and dense (1234 kg/m3) water; spontaneous precipitation of minerals in an oversaturated environment; origin of the unusual chemical composition of the brine; existence of life in extreme environments; use of lake level fluctuations as a paleoclimatic indicator; and effects on the environment of human intervention versus natural climatic variability. Although the Dead Sea covers a small area on a global scale, it is nevertheless one of the largest natural laboratories for these types of research on Earth. These reasons make the Dead Sea a fascinating topic for the curious mind.

  6. Biomechanics of Tetrahymena escaping from a dead end

    2018-01-01

    Understanding the behaviours of swimming microorganisms in various environments is important for understanding cell distribution and growth in nature and industry. However, cell behaviour in complex geometries is largely unknown. In this study, we used Tetrahymena thermophila as a model microorganism and experimentally investigated cell behaviour between two flat plates with a small angle. In this configuration, the geometry provided a ‘dead end' line where the two flat plates made contact. The results showed that cells tended to escape from the dead end line more by hydrodynamics than by a biological reaction. In the case of hydrodynamic escape, the cell trajectories were symmetric as they swam to and from the dead end line. Near the dead end line, T. thermophila cells were compressed between the two flat plates while cilia kept beating with reduced frequency; those cells again showed symmetric trajectories, although the swimming velocity decreased. These behaviours were well reproduced by our computational model based on biomechanics. The mechanism of hydrodynamic escape can be understood in terms of the torque balance induced by lubrication flow. We therefore conclude that a cell's escape from the dead end was assisted by hydrodynamics. These findings pave the way for understanding cell behaviour and distribution in complex geometries.

    The scientific study of death across animal taxa-comparative thanatology-investigates how animals respond behaviourally, physiologically and psychologically to dead conspecifics, and the processes behind such responses. Several species of cetaceans have been long known to care for, attend to, be aroused by, or show interest in dead or dying individuals. We investigated patterns and variation in cetacean responses to dead conspecifics across cetacean taxa based on a comprehensive literature review. We analysed 78 records reported between 1970 and 2016, involving 20 of the 88 extant cetacean species. We adopted a weighted comparative approach to take observation effort into account and found that odontocetes (toothed cetaceans) were much more likely than mysticetes (baleen whales) to attend to dead conspecifics. Dolphins (Delphinidae) had the greatest occurrence of attentive behaviour (92.3% of all records), with a weighed attendance index 18 times greater than the average of all other cetacean families. Two dolphin genera, Sousa and Tursiops, constituted 55.1% of all cetacean records (N=43) and showed the highest incidence of attentive behaviour. Results of analyses intended to investigate the reasons behind these differences suggested that encephalisation may be an important predictor, consistent with the "social brain" hypothesis. Among attending individuals or groups of known sex (N=28), the majority (75.0%) were adult females with dead calves or juveniles (possibly their own offspring, with exceptions), consistent with the strong mother-calf bond, or, in a few cases, with the bond between mothers and other females in the group. The remaining records (25.0%) involved males either showing sexual interest in a dead adult or subadult, or carrying a dead calf in the presence of females. Because an inanimate individual is potentially rescuable, responses to dead conspecifics-especially by females-can be explained at least in part by attempts to revive and protect

    Fever in children is a common concern for parents and one of the most frequent presenting complaints in emergency department visits, often involving non-pediatric emergency physicians. Although the incidence of serious infections has decreased after the introduction of conjugate vaccines, fever remains a major cause of laboratory investigation and hospital admissions. Furthermore, antipyretics are the most common medications administered to children. We review the epidemiology and measurement of fever, the meaning of fever and associated clinical signs in children of different ages and under special conditions, including fever in children with cognitive impairment, recurrent fevers, and fever of unknown origin. While the majority of febrile children have mild, self-resolving viral illness, a minority may be at risk of life-threatening infections. Clinical assessment differs markedly from adult patients. Hands-off evaluation is paramount for a correct evaluation of breathing, circulation and level of interaction. Laboratory markers and clinical prediction rules provide limited help in identifying children at risk for serious infections; however, clinical examination, prudent utilization of laboratory tests, and post-discharge guidance (“safety netting”) remain the cornerstone of safe management of febrile children.

    Adverse reactions to mesalamine, a treatment used to induce and maintain remission in inflammatory bowel diseases, particularly ulcerative colitis, have been described in the literature as case reports. This case illustrates an unusual adverse reaction. Our patient developed an isolated fever of unexplained etiology, which was found to be related to mesalamine treatment. A 22-year-old patient diagnosed with ulcerative colitis developed a fever with rigors and anorexia 10 d after starting oral mesalamine while his colitis was clinically resolving. Testing revealed no infection. A mesalamine-induced fever was considered, and treatment was stopped, which led to spontaneous resolution of the fever. The diagnosis was confirmed by reintroducing the mesalamine. One year later, this side effect was noticed again in the same patient after he was administered topical mesalamine. This reaction to mesalamine seems to be idiosyncratic, and the mechanism that induces fever remains unclear. Fever encountered in the course of a mesalamine treatment in ulcerative colitis must be considered a mesalamine-induced fever when it cannot be explained by the disease activity, an associated extraintestinal manifestation, or an infectious etiology.

    When shared by people who inject drugs, needles and syringes with different dead space may affect the probability of HIV and hepatitis C virus (HCV) transmission differently. We measured dead space in 56 needle and syringe combinations obtained from needle and syringe programs across 17 countries in Europe and Asia. We also calculated the amounts of blood and HIV that would remain in different combinations following injection and rinsing. Syringe barrel capacities ranged from 0.5 to 20 mL. Needles ranged in length from 8 to 38 mm. The average dead space was 3 μL in low dead space syringes with permanently attached needles, 13 μL in high dead space syringes with low dead space needles, 45 μL in low dead space syringes with high dead space needles, and 99 μL in high dead space syringes with high dead space needles. Among low dead space designs, calculated volumes of blood and HIV viral burden were lowest for low dead space syringes with permanently attached needles and highest for low dead space syringes with high dead space needles. The dead space in different low dead space needle and syringe combinations varied substantially. To reduce HIV transmission related to syringe sharing, needle and syringe programs need to combine this knowledge with the needs of their clients.

  12. Can dead zones create structures like a transition disk?

    NASA Astrophysics Data System (ADS)

    Pinilla, Paola; Flock, Mario; Ovelar, Maria de Juan; Birnstiel, Til

    2016-12-01

    Context. Regions of low ionisation where the activity of the magneto-rotational instability is suppressed, the so-called dead zones, have been suggested to explain gaps and asymmetries of transition disks. Dead zones are therefore a potential cause for the observational signatures of transition disks without requiring the presence of embedded planets. Aims: We investigate the gas and dust evolution simultaneously assuming simplified prescriptions for a dead zone and a magnetohydrodynamic (MHD) wind acting on the disk. We explore whether the resulting gas and dust distribution can create signatures similar to those observed in transition disks. Methods: We imposed a dead zone and/or an MHD wind in the radial evolution of gas and dust in protoplanetary disks. For the dust evolution, we included the transport, growth, and fragmentation of dust particles. To compare with observations, we produced synthetic images in scattered optical light and in thermal emission at mm wavelengths. Results: In all models with a dead zone, a bump in the gas surface density is produced that is able to efficiently trap large particles (≳ 1 mm) at the outer edge of the dead zone. The gas bump reaches an amplitude of a factor of 5, which can be enhanced by the presence of an MHD wind that removes mass from the inner disk. While our 1D simulations suggest that such a structure can be present only for 1 Myr, the structure may be maintained for a longer time when more realistic 2D/3D simulations are performed. In the synthetic images, gap-like low-emission regions are seen at scattered light and in thermal emission at mm wavelengths, as previously predicted in the case of planet-disk interaction. Conclusions: Main signatures of transition disks can be reproduced by assuming a dead zone in the disk, such as gap-like structure in scattered light and millimetre continuum emission, and a lower gas surface density within the dead zone. Previous studies showed that the Rossby wave instability can

    We describe the first molecular confirmation of Rickettsia rickettsii, the cause of Rocky Mountain spotted fever (RMSF), from a tick vector, Amblyomma cajennense, and from a cluster of fatal spotted fever cases in Argentina. Questing A. cajennense ticks were collected at or near sites of presumed or confirmed cases of spotted fever rickettsiosis in Jujuy Province and evaluated by polymerase chain reaction assays for spotted fever group rickettsiae. DNA of R. rickettsii was amplified from a pool of A. cajennense ticks and from tissues of one of four patients who died during 2003-2004 after illnesses characterized by high fever, severe headache, myalgias, and petechial rash. The diagnosis of spotted fever rickettsiosis was confirmed in the other patients by indirect immunofluorescence antibody and immunohistochemical staining techniques. These findings show the existence of RMSF in Argentina and emphasize the need for clinicians throughout the Americas to consider RMSF in patients with febrile rash illnesses.

    Data about prognostic value of postoperative fever in gastric cancer was lacking. Thus, the present study aims to investigate the prognostic value of postoperative fever in gastric cancer. From September 2008 to March 2015, 2938 gastric cancer patients were enrolled in the present study. Clinicopathological features were recoded. The association between postoperative fever and prognosis of gastric cancer were analyzed. There were 2294 male (78.1%) and 644 female (21.9%). Seven hundred and fifty-six patients suffered from fever. Among them, the duration of fever less than 48h occurred in 508 cases, and duration of fever over 48h occurred in 248 cases. Univariate and multivariate analysis showed that postoperative fever was an independent risk factor for prognosis of gastric cancer ( P < 0.001). For the entire cohort, duration of fever over 48h was significantly associated with decreased survival ( P < 0.001). In subgroup analysis, duration of fever over 48h was significantly associated with poor prognosis of stage I and II gastric cancer (both P < 0.001). However, postoperative fever was not associated with the prognosis of stage III gastric cancer ( P = 0.334). Considering the type of gastrectomy, postoperative fever was not associated with the prognosis of patients with proximal ( P = 0.318) and distal gastrectomy ( P = 0.806), but duration of fever over 48h was significantly associated with poor prognosis of patients with total gastrectomy ( P = 0.004). In conclusion, postoperative fever was associated with poor prognosis of gastric cancer.

    The Dead Sea, the deepest and most saline lake on earth, has been known from biblical times for its healing properties. The aim of this systematic review was to present critically the level of evidence for the claims of therapeutic effects of Dead Sea treatments in several rheumatologic diseases and psoriasis as well as to review these treatments' safety. All articles cited in MEDLINE under the query, "Dead Sea," were reviewed. We found bona fide evidence that Dead Sea treatments are especially effective in psoriasis due to both the special characteristics of solar ultraviolet radiation in the Dead Sea and the Dead Sea water balneotherapy. Dead Sea mud and Dead Sea balneotherapy have been found to be beneficial in rheumatologic diseases, including rheumatoid arthritis, psoriatic arthritis, ankylosing spondylitis, and knee osteoarthritis. In the safety analysis, we found no evidence for an increase in skin neoplasia, although skin actinic damage seems to be increased in patients treated in the Dead Sea. Dead Sea treatments do not lead to worsening of blood pressure. Substantial ingestion of Dead Sea water (generally in unusual near-drowning cases) is toxic and can result in cardiac rhythm disturbances because of electrolyte concentration abnormalities. Laboratory analysis of Dead Sea mud did not reveal mineral concentrations that could represent a health concern for their intended use. Dead Sea treatments are beneficial in several rheumatologic diseases and psoriasis and have a good safety profile. Copyright © 2012 Elsevier Inc. All rights reserved.

    Dengue fever, also known as breakbone fever, is a mosquito-borne infectious tropical disease caused by the dengue virus. Symptoms include fever, headache, muscle and joint pains, and a characteristic skin rash that is similar to measles. In a small proportion of cases, the disease develops into life-threatening dengue hemorrhagic fever, which results in bleeding, thrombocytopenia, and leakage of blood plasma, or into dengue shock syndrome, in which dangerously low blood pressure occurs. Treatment of acute dengue fever is supportive, with either oral or intravenous rehydration for mild or moderate disease and use of intravenous fluids and blood transfusion for more severe cases. Along with attempts to eliminate the mosquito vector, work is ongoing to develop a vaccine and medications targeted directly at the virus.

    Coastal regions of eutrophication-driven oxygen depletion are widespread and increasing in number. Also known as dead zones, these regions take their name from the deleterious effects of hypoxia (dissolved oxygen less than 2 mg/L) on shrimp, demersal fish, and other animal life. Dead zones result from nutrient enrichment of primary production, concomitant consumption by chemoorganotrophic aerobic microorganisms, and strong stratification that prevents ventilation of bottom water. One of the largest dead zones in the world occurs seasonally in the northern Gulf of Mexico (nGOM), where hypoxia can reach up to 22,000 square kilometers. While this dead zone shares many features with more well-known marine oxygen minimum zones, it is nevertheless understudied with regards to the microbial assemblages involved in biogeochemical cycling. We performed metagenomic and metatranscriptomic sequencing on six samples from the 2013 nGOM dead zone from both hypoxic and oxic bottom waters. Assembly and binning led to the recovery of over fifty partial to nearly complete metagenomes from key microbial taxa previously determined to be numerically abundant from 16S rRNA data, such as Thaumarcheaota, Marine Group II Euryarchaeota, SAR406, SAR324, Synechococcus spp., and Planctomycetes. These results provide information about the roles of these taxa in the nGOM dead zone, and opportunities for comparing this region of low oxygen to others around the globe.

    On December 17, 1903, the brothers Wilbur and Orville Wright flew the world's first successful airplane, following this with the first military airplane in 1908. (The 1908 Flyer was built by the brothers in response to a 1907 requirements specification for a 2-place aircraft capable of flying at 40 mph and able to be broken down and transported in a horse-drawn wagon. Technically, since it crashed during its demonstration program and was not formally delivered to the Army, it never became Army property. But the trials had been so impressive that the Army ordered a second, delivered in 1909.) Just six years later, Europe erupted in a general war. Often portrayed as a sideshow to the war on land and sea, the air war heralded the advent of mechanized warfare, the airplane being one of four great technological advances--the submarine, the tank, and radio communication--that, together, revolutionized military affairs. Aircraft reconnaissance influenced the conduct of military operations from the war's earliest days, and airborne observers routinely governed the fall of artillery barrages, crucially important in an artillery-dominant war.

  6. MAGNETIZED ACCRETION AND DEAD ZONES IN PROTOSTELLAR DISKS

    Dzyurkevich, Natalia; Henning, Thomas; Turner, Neal J.

    The edges of magnetically dead zones in protostellar disks have been proposed as locations where density bumps may arise, trapping planetesimals and helping form planets. Magneto-rotational turbulence in magnetically active zones provides both accretion of gas on the star and transport of mass to the dead zone. We investigate the location of the magnetically active regions in a protostellar disk around a solar-type star, varying the disk temperature, surface density profile, and dust-to-gas ratio. We also consider stellar masses between 0.4 and 2 M{sub Sun }, with corresponding adjustments in the disk mass and temperature. The dead zone's size andmore » shape are found using the Elsasser number criterion with conductivities including the contributions from ions, electrons, and charged fractal dust aggregates. The charged species' abundances are found using the approach proposed by Okuzumi. The dead zone is in most cases defined by the ambipolar diffusion. In our maps, the dead zone takes a variety of shapes, including a fish tail pointing away from the star and islands located on and off the midplane. The corresponding accretion rates vary with radius, indicating locations where the surface density will increase over time, and others where it will decrease. We show that density bumps do not readily grow near the dead zone's outer edge, independently of the disk parameters and the dust properties. Instead, the accretion rate peaks at the radius where the gas-phase metals freeze out. This could lead to clearing a valley in the surface density, and to a trap for pebbles located just outside the metal freezeout line.« less

    2013-01-01

    Scavenging (feeding on dead prey) has been demonstrated across a number of spider families, yet the implications of feeding on dead prey for the growth and development of individuals and population is unknown. In this study we compare the growth, development, and predatory activity of two species of spiders that were fed on live and dead prey. Pardosa astrigera (Lycosidae) and Hylyphantes graminicola (Lyniphiidae) were fed live or dead fruit flies, Drosophila melanogaster. The survival of P. astrigera and H. graminicola was not affected by prey type. The duration of late instars of P. astrigera fed dead prey were longer and mature spiders had less protein content than those fed live prey, whereas there were no differences in the rate of H. graminicola development, but the mass of mature spiders fed dead prey was greater than those fed live prey. Predation rates by P. astrigera did not differ between the two prey types, but H. graminicola had a higher rate of predation on dead than alive prey, presumably because the dead flies were easier to catch and handle. Overall, the growth, development and reproduction of H. graminicola reared with dead flies was better than those reared on live flies, yet for the larger P. astrigera, dead prey may suit smaller instars but mature spiders may be best maintained with live prey. We have clearly demonstrated that dead prey may be suitable for rearing spiders, although the success of the spiders fed such prey appears size- and species specific.

    Defining the appropriate threshold at which to initiate a fever workup is imperative to promote patient safety, appropriate resource utilization, and antibiotic stewardship. Our group performed a systematic review of the available literature on perioperative fever (POF) workups in orthopaedic patients to evaluate the frequency, timing and utility of blood cultures (BC) and other investigations in the POF workup, to determine the clinical relevance of any infections and to evaluate their cost effectiveness. Studies were identified by searching MEDLINE, EMBASE, Pubmed, Cochrane and Google Scholar for articles through September 2016. Forty-nine articles were retrieved and 22 articles met the pre-determined inclusion criteria. Proportions of positive studies were noted and averaged using random effects analysis. Post-operative pyrexia ranged in prevalence between 8.1% and 87.3%. The studies routinely performed during a fever workup had wide ranges of diagnostic yield, including chest X-rays from 0% to 40%, urinalyses from 8.2% to 38.7%, urine cultures from 0% to 22.4% and BC from 0% to 13.3%. Only two patients with positive BC developed clinical sepsis. Cost per fever evaluation ranged from $350 to $950. The findings of this review suggest that early post-operative fever is an expected event following orthopaedic surgery. Based on the available literature, any kind of workup in the absence of localizing symptoms in the third post-operative day or before is unwarranted and is an inappropriate use of hospital resources.

    To test the hypothesis that fever was more frequent in critically ill patients with brain injury when compared to nonneurological patients and to study its effect on in-hospital case fatality. Retrospective matched cohort study utilizing a single-center prospectively compiled registry. Critically ill neurological patients ≥18 years and consecutively admitted to the intensive care unit (ICU) with acute ischemic stroke (AIS), intracerebral hemorrhage (ICH), and traumatic brain injury (TBI) were selected. Patients were matched by sex, age, and Acute Physiology and Chronic Health Evaluation II (APACHE-II) to a cohort of nonneurological patients. Fever was defined as any temperature ≥37.5°C within the first 24 hours upon admission to the ICU. The primary outcome measure was in-hospital case fatality. Mean age among neurological patients was 65.6 ± 15 years, 46% were men, and median APACHE-II was 15 (interquartile range 11-20). There were 18% AIS, 27% ICH, and 6% TBI. More neurological patients experienced fever than nonneurological patients (59% vs 47%, P = .007). The mean hospital length of stay was higher for nonneurological patients (18 ± 20 vs 14 ± 15 days, P = .007), and more neurological patients were dead at hospital discharge (29% vs 20%, P < .0001). After risk factor adjustment, diagnosis (neurological vs nonneurological), and the probability of being exposed to fever (propensity score), the following variables were associated with higher in-hospital case fatality: APACHE-II, neurological diagnosis, mean arterial pressure, cardiovascular and respiratory dysfunction in ICU, and fever (odds ratio 1.9, 95% confidence interval 1.04-3.6, P = .04). These data suggest that fever is a frequent occurrence after brain injury, and that it is independently associated with in-hospital case fatality. © The Author(s) 2013.

    2014-02-01

    When the Anglo-Boer War broke out in October 1899, Arthur Conan Doyle, a retired ophthalmologist, was already famous as the creator of Sherlock Holmes. Motivated by patriotism and adventure, Doyle joined the medical staff of a private field hospital endowed by philanthropist John Langman (1846-1928). Langman Hospital opened in Bloemfontein, South Africa, at the height of that city's typhoid fever epidemic which raged from April to June 1900. There were nearly 5000 cases of typhoid and 1000 deaths but official statistics do not truly reflect the magnitude of the suffering. Doyle argued that the British Army had made a major mistake by not making antityphoid inoculation compulsory. Because of the new vaccine's side effects, 95% of the soldiers refused immunization. Despite his strong opinions, Doyle failed to press the issue of compulsory inoculation when he testified before two Royal Commissions investigating the medical and military management of the war in South Africa. One can only imagine how the army might have benefited from the new idea of prophylactic vaccination in preventive medicine if Doyle had not let these opportunities slip away. As a consequence, antityphoid inoculation was still voluntary when Great Britain entered World War I in August 1914.

    Climate change can increase the risk of conditions that exceed human thermoregulatory capacity. Although numerous studies report increased mortality associated with extreme heat events, quantifying the global risk of heat-related mortality remains challenging due to a lack of comparable data on heat-related deaths. Here we conducted a global analysis of documented lethal heat events to identify the climatic conditions associated with human death and then quantified the current and projected occurrence of such deadly climatic conditions worldwide. We reviewed papers published between 1980 and 2014, and found 783 cases of excess human mortality associated with heat from 164 cities in 36 countries. Based on the climatic conditions of those lethal heat events, we identified a global threshold beyond which daily mean surface air temperature and relative humidity become deadly. Around 30% of the world's population is currently exposed to climatic conditions exceeding this deadly threshold for at least 20 days a year. By 2100, this percentage is projected to increase to ~48% under a scenario with drastic reductions of greenhouse gas emissions and ~74% under a scenario of growing emissions. An increasing threat to human life from excess heat now seems almost inevitable, but will be greatly aggravated if greenhouse gases are not considerably reduced.

    Objectives To determine how many veterans in a random sample of British veterans who served in the Gulf war believe they have “Gulf war syndrome,” to examine factors associated with the presence of this belief, and to compare the health status of those who believe they have Gulf war syndrome with those who do not. Design Questionnaire study asking British Gulf war veterans whether they believe they have Gulf war syndrome and about symptoms, fatigue, psychological distress, post-traumatic stress, physical functioning, and their perception of health. Participants 2961 respondents to questionnaires sent out to a random sample of 4250 Gulf war veterans (69.7%). Main outcome measure The proportion of veterans who believe they have Gulf war syndrome. Results Overall, 17.3% (95% confidence interval 15.9 to 18.7) of the respondents believed they had Gulf war syndrome. The belief was associated with the veteran having poor health, not serving in the army when responding to the questionnaire, and having received a high number of vaccinations before deployment to the Gulf. The strongest association was knowing another person who also thought they had Gulf war syndrome. Conclusions Substantial numbers of British Gulf war veterans believe they have Gulf war syndrome, which is associated with psychological distress, a high number of symptoms, and some reduction in activity levels. A combination of biological, psychological, and sociological factors are associated with the belief, and these factors should be addressed in clinical practice.

  20. Are Brain Dead Individuals Dead? Grounds for Reasonable Doubt.

    PubMed

    Brugger, E Christian

    2016-06-01

    According to the biological definition of death, a human body that has not lost the capacity to holistically organize itself is the body of a living human individual. Reasonable doubt against the conclusion that it has lost the capacity exists when the body appears to express it and no evidence to the contrary is sufficient to rule out reasonable doubt against the conclusion that the apparent expression is a true expression (i.e., when the conclusion that what appears to be holistic organization is in fact holistic organization remains a reasonable explanatory hypothesis in light of the best evidence to the contrary). This essay argues that the evidence and arguments against the conclusion that the signs of complex bodily integration exhibited in ventilated brain dead bodies are true expressions of somatic integration are unpersuasive; that is, they are not adequate to exclude reasonable doubt against the conclusion that BD bodies are dead. Since we should not treat as corpses what for all we know might be living human beings, it follows that we have an obligation to treat BD individuals as if they were living human beings. © The Author 2016.

    Control of typhoid fever relies on clinical information, diagnosis, and an understanding for the epidemiology of the disease. Despite the breadth of work done so far, much is not known about the biology of this human-adapted bacterial pathogen and the complexity of the disease in endemic areas, especially those in Africa. The main barriers to control are vaccines that are not immunogenic in very young children and the development of multidrug resistance, which threatens efficacy of antimicrobial chemotherapy. Clinicians, microbiologists, and epidemiologists worldwide need to be familiar with shifting trends in enteric fever. This knowledge is crucial, both to control the disease and to manage cases. Additionally, salmonella serovars that cause human infection can change over time and location. In areas of Asia, multidrug-resistant Salmonella enterica serovar Typhi (S Typhi) has been the main cause of enteric fever, but now S Typhi is being displaced by infections with drug-resistant S enterica serovar Paratyphi A. New conjugate vaccines are imminent and new treatments have been promised, but the engagement of local medical and public health institutions in endemic areas is needed to allow surveillance and to implement control measures.

    Typhoid and paratyphoid fever remain a global health problem, which - in non-endemic countries - are mainly seen in travelers, particularly in VFRs (visiting friends and relatives), with occasional local outbreaks occurring. A rise in anti-microbial resistance emphasizes the role of preventive measures, especially vaccinations against typhoid and paratyphoid fever for travelers visiting endemic countries. Areas covered: This state-of-the-art review recapitulates the epidemiology and mechanisms of disease of typhoid and paratyphoid fever, depicts the perspective of non-endemic countries and travelers (VFRs), and collectively presents current European recommendations for typhoid fever vaccination. We provide a brief overview of available (and developmental) vaccines in Europe, present current data on cross-protection to S. Paratyphi, and aim to provide a background for typhoid vaccine decision-making in travelers. Expert commentary: European recommendations are not harmonized. Experts must assess vaccination of travelers based on current country-specific recommendations. Travel health practitioners should be aware of the issues surrounding vaccination of travelers and be motivated to increase awareness of typhoid and paratyphoid fever risks.

    Yemen has witnessed several dengue fever outbreaks coincident with the social unrest and war in the country. The aim of the present study was to describe the knowledge, attitudes and practices (KAPs) of at-risk urban populations residing in Taiz, southwest of Yemen. In addition, factors possibly associated with poor preventive practices were investigated. A household-based, cross-sectional survey was conducted in three urban districts encompassing 383 households. Data on the socio-demographic characteristics and KAPs of the participating household heads were collected using a pre-designed, structured questionnaire. The association of socio-demographic characteristics, knowledge and attitudes of the population with poor preventive practices against dengue fever was then analyzed using logistic regression. More than 90.0 % of respondent household heads had correct knowledge about fever, headache and joint pain as common signs and symptoms of dengue fever. Moreover, muscular pain and bleeding were perceived by more than 80.0 % of the respondents as being associated with dengue fever; however, only 65.0 % of the respondents reported skin rash as a sign of dengue fever. More than 95.0 % of respondents agreed about the seriousness and possible transmission of dengue fever; however, negative attitudes regarding the facts of being at risk of the disease and that the infection is preventable were expressed by 15.0 % of respondents. Despite the good level of knowledge and attitudes of the respondent population, poor preventive practices were common. Bivariate analysis identified poor knowledge of dengue signs and symptoms (OR = 2.1, 95 % CI = 1.24-3.68; P = 0.005) and its vector (OR = 2.1, 95 % CI = 1.14-3.84; P = 0.016) as factors significantly associated with poor preventive practices. However, multivariable analysis showed that poor knowledge of the vector is an independent predictor of poor preventive practices of the population (adjusted

Dead and dying trees don't awe us with their beauty; they just stand or lie there on the forest floor, offering no promise of lumber or other wood products we need. But if we look more closely at such trees, we may see lots of life in them: a raccoon family huddled in a burrow, a downy woodpecker excavating another...

  5. The Dead Donor Rule: Can It Withstand Critical Scrutiny?

    PubMed Central

    2010-01-01

    Transplantation of vital organs has been premised ethically and legally on “the dead donor rule” (DDR)—the requirement that donors are determined to be dead before these organs are procured. Nevertheless, scholars have argued cogently that donors of vital organs, including those diagnosed as “brain dead” and those declared dead according to cardiopulmonary criteria, are not in fact dead at the time that vital organs are being procured. In this article, we challenge the normative rationale for the DDR by rejecting the underlying premise that it is necessarily wrong for physicians to cause the death of patients and the claim that abandoning this rule would exploit vulnerable patients. We contend that it is ethical to procure vital organs from living patients sustained on life support prior to treatment withdrawal, provided that there is valid consent for both withdrawing treatment and organ donation. However, the conservatism of medical ethics and practical concerns make it doubtful that the DDR will be abandoned in the near future. This leaves the current practice of organ transplantation based on the “moral fiction” that donors are dead when vital organs are procured. PMID:20439355

    Exposure to war-related experiences can comprise a broad variety of experiences and the very nature of certain war-related events has generally been neglected. To examine the long-term outcomes of war-related death of family members, the authors investigated the prevalence rates of major depressive episode (MDE), anxiety disorders, and quality of life among civilian war survivors with or without war-related death of first-degree family members 9 years after the war in Kosovo. Compared to participants without war-related death of family members, those who had experienced such loss had signficantly higher prevalence rates of MDE, posttraumatic stress disorder, and generalized anxiety disorder, and reported a lower quality of life 9 years after the war. These results indicate that bereaved civilian survivors of war experience significant mental health problems many years after the war.

  9. Donation after circulatory death: burying the dead donor rule.

    Rodríguez-Arias, David; Smith, Maxwell J; Lazar, Neil M

    2011-08-01

    Despite continuing controversies regarding the vital status of both brain-dead donors and individuals who undergo donation after circulatory death (DCD), respecting the dead donor rule (DDR) remains the standard moral framework for organ procurement. The DDR increases organ supply without jeopardizing trust in transplantation systems, reassuring society that donors will not experience harm during organ procurement. While the assumption that individuals cannot be harmed once they are dead is reasonable in the case of brain-dead protocols, we argue that the DDR is not an acceptable strategy to protect donors from harm in DCD protocols. We propose a threefold alternative to justify organ procurement practices: (1) ensuring that donors are sufficiently protected from harm; (2) ensuring that they are respected through informed consent; and (3) ensuring that society is fully informed of the inherently debatable nature of any criterion to declare death.

  10. FORMATION OF CIRCUMBINARY PLANETS IN A DEAD ZONE

    Martin, Rebecca G.; Armitage, Philip J.; Alexander, Richard D.

    Circumbinary planets have been observed at orbital radii where binary perturbations may have significant effects on the gas disk structure, on planetesimal velocity dispersion, and on the coupling between turbulence and planetesimals. Here, we note that the impact of all of these effects on planet formation is qualitatively altered if the circumbinary disk structure is layered, with a non-turbulent midplane layer (dead zone) and strongly turbulent surface layers. For close binaries, we find that the dead zone typically extends from a radius close to the inner disk edge up to a radius of around 10-20 AU from the center ofmore » mass of the binary. The peak in the surface density occurs within the dead zone, far from the inner disk edge, close to the snow line, and may act as a trap for aerodynamically coupled solids. We suggest that circumbinary planet formation may be easier near this preferential location than for disks around single stars. However, dead zones around wide binaries are less likely, and hence planet formation may be more difficult there.« less

    West Nile fever (WNF) and Rift Valley fever (RVF) are emerging diseases causing epidemics outside their natural range of distribution. West Nile virus (WNV) circulates widely and harmlessly in the old world among birds as amplifying hosts, and horses and humans as accidental dead-end hosts. Rift Valley fever virus (RVFV) re-emerges periodically in Africa causing massive outbreaks. In the Maghreb, eco-climatic and entomologic conditions are favourable for WNV and RVFV emergence. Both viruses are transmitted by mosquitoes belonging to the Culex pipiens complex. We evaluated the ability of different populations of Cx. pipiens from North Africa to transmit WNV and the avirulent RVFV Clone 13 strain. Mosquitoes collected in Algeria, Morocco, and Tunisia during the summer 2010 were experimentally infected with WNV and RVFV Clone 13 strain at titers of 107.8 and 108.5 plaque forming units/mL, respectively. Disseminated infection and transmission rates were estimated 14–21 days following the exposure to the infectious blood-meal. We show that 14 days after exposure to WNV, all mosquito st developed a high disseminated infection and were able to excrete infectious saliva. However, only 69.2% of mosquito strains developed a disseminated infection with RVFV Clone 13 strain, and among them, 77.8% were able to deliver virus through saliva. Thus, Cx. pipiens from the Maghreb are efficient experimental vectors to transmit WNV and to a lesser extent, RVFV Clone 13 strain. The epidemiologic importance of our findings should be considered in the light of other parameters related to mosquito ecology and biology. PMID:22693557

    Nasal high flow (NHF) reduces minute ventilation and ventilatory loads during sleep but the mechanisms are not clear. We hypothesised NHF reduces ventilation in proportion to physiological but not anatomical dead space.11 subjects (five controls and six chronic obstructive pulmonary disease (COPD) patients) underwent polysomnography with transcutaneous carbon dioxide (CO 2 ) monitoring under a metabolic hood. During stable non-rapid eye movement stage 2 sleep, subjects received NHF (20 L·min -1 ) intermittently for periods of 5-10 min. We measured CO 2 production and calculated dead space ventilation.Controls and COPD patients responded similarly to NHF. NHF reduced minute ventilation (from 5.6±0.4 to 4.8±0.4 L·min -1 ; p<0.05) and tidal volume (from 0.34±0.03 to 0.3±0.03 L; p<0.05) without a change in energy expenditure, transcutaneous CO 2 or alveolar ventilation. There was a significant decrease in dead space ventilation (from 2.5±0.4 to 1.6±0.4 L·min -1 ; p<0.05), but not in respiratory rate. The reduction in dead space ventilation correlated with baseline physiological dead space fraction (r 2 =0.36; p<0.05), but not with respiratory rate or anatomical dead space volume.During sleep, NHF decreases minute ventilation due to an overall reduction in dead space ventilation in proportion to the extent of baseline physiological dead space fraction.

    Typhoid fever remains a major health problem worldwide, in contrast to Chile, where this disease is an isolated finding. Clinical presentation is varied, mainly presenting with fever, malaise, abdominal discomfort, and nonspecific symptoms often confused with other causes of febrile syndrome. We report a six-year-old, male patient presenting with fever of two weeks associated with gastrointestinal symptoms, malaise, hepatomegaly and elevated liver enzymes. Differential diagnoses were considered and a Widal reaction and two blood cultures were requested; both came back positive, confirming the diagnosis of typhoid fever caused by Salmonella typhi. Prior to diagnosis confirmation, empirical treatment was initiated with ceftriaxone and metronidazole, with partial response; then drug therapy was adjusted according to ciprofloxacin susceptibility testing with a favorable clinical response. We discuss diagnostic methods and treatment of enteric fever with special emphasis on typhoid fever.

  20. Fever in Children: Should it be Treated?

    PubMed Central

    Habbick, Brian F.

    1988-01-01

    Fever, which is the regulation of body temperature at an elevated level, must be differentiated from hyperthermia. The pathogenesis of fever involves exogenous pyrogens acting on macrophages/monocytes to produce the endogenous pyrogen, interleukin-1, which acts on the thermoregulatory centre and also has important effects on the body's immune responses to infection. Fever by itself is rarely harmful, and there is no evidence that febrile seizures produce long-term sequelae. On the other hand, fever may be part of the body's innate protection against infection. The main reason for treating a fever in a child is to relieve discomfort. Acetaminophen should be the drug of first choice in treatment, and sponging, if used at all, should be employed only after acetaminophen has been given first. Education of parents about fever management can be helpful. PMID:21253180

    Fever is one of the most common complaints presented to the Paediatric Emergency Unit (PEU). It is a sign that there is an underlying pathologic process, the most common being infection. Many childhood illnesses are accompanied by fever, many of which are treated at home prior to presentation to hospital. Most febrile episodes are benign. Caregivers are the primary contacts to children with fever. Adequate caregivers' knowledge and proper management of fever at home leads to better management of febrile illnesses and reduces complications. To determine the caregivers' knowledge and practices regarding fever in children. A cross-sectional study. Peadiatric Emergency Unit at Kenyatta National Hospital (KNH) SUBJECTS: Two hundred and fifty caregivers of children under 12 years presenting with fever in August to October 2011 to the PEU. Three quarters of the caregivers' defined fever correctly. Their knowledge on the normal body was at 47.6%. Infection was cited as the leading cause of fever (95.2%). Brain damage (77.6%) and dehydration (65.6%) were viewed as the most common complication. Fever was treated at home by 97.2% of caregivers, most of them used medication. Fever was defined correctly by 75.2% of the study participants and a majority of them used touch to detect fever. Fever was managed at home with medications. Public Health Education should be implemented in order to enlighten caregivers on fever and advocate for the use of a clinical thermometer to monitor fever at home.

    Three exogenous pyrogens (Escherichia coli lipopolysaccharide, synthetic double-stranded ribonucleic acid. Newcastle disease virus) were compared with respect to their mechanisms of fever induction in rabbits. All inducers stimulated the production of an endogenous pyrogen demonstrated in the blood as well as prostaglandins of the E group, and of cyclic adenosine 3',5'-monophosphate in the cerebrospinal fluid. The concentrations of these compounds were elevated approximately twofold as compared to the controls. Independently of the mode of induction, the fever reaction could be prevented by pretreatment with 5 mg of cycloheximide per kg, although the three fever mediators were induced as in febrile animals. Consequently, at least one additional fever mediator that is sensitive to a 30 to 50% inhibition of protein synthesis by cycloheximide has to be postulated. The comparable reactions of the rabbits after administration of different pyrogens argues for a similar fever mechanism. In contrast to fever induction there was no stimulation of endogenous pyrogen, prostaglandins of the E group, and cyclic adenosine 3',5'-monophosphate in hyperthermia as a consequence of exposure of the animals to exogenous overheating. Furthermore, hyperthermia could not be prevented by cycloheximide. PMID:185148

    Dengue fever, rickettsial diseases, and Q fever are acute febrile illnesses with similar manifestations in tropical areas. Early differential diagnosis of scrub typhus, murine typhus, and Q fever from dengue fever may be made by understanding the distinguishing clinical characteristics and the significance of demographic and weather factors. We conducted a retrospective study to identify clinical, demographic, and meteorological characteristics of 454 dengue fever, 178 scrub typhus, 143 Q fever, and 81 murine typhus cases in three Taiwan hospitals. Case numbers of murine typhus and Q fever correlated significantly with temperature and rainfall; the scrub typhus case number was only significantly related with temperature. Neither temperature nor rainfall correlated with the case number of dengue fever. The rarity of dengue fever cases from January to June in Taiwan may be a helpful clue for diagnosis in the area. A male predominance was observed, as the male-to-female rate was 2.1 for murine typhus and 7.4 for Q fever. Multivariate analysis revealed the following six important factors for differentiating the rickettsial diseases and Q fever group from the dengue fever group: fever ≥8 days, alanine aminotransferase > aspartate aminotransferase, platelets >63,000/mL, C-reactive protein >31.9 mg/L, absence of bone pain, and absence of a bleeding syndrome. Understanding the rarity of dengue in the first half of a year in Taiwan and the six differentiating factors may help facilitate the early differential diagnosis of rickettsial diseases and Q fever from dengue fever, permitting early antibiotic treatment.

  6. A review of the physiology of fever in birds.

    Gray, David A; Marais, Manette; Maloney, Shane K

    2013-04-01

    While fever is known to occur in invertebrates and vertebrates, the mechanisms of fever in animals other than mammals have received scant attention. We look initially at the recognition, by the avian immune system, of pathogen associated molecular patterns and the likely role of toll-like receptors in signaling the presence of bacteria and viruses. Several mediators of fever are subsequently released by immune cells, including interleukin-6 and interleukin-1β, that eventually reach the brain and alter thermoregulatory function. As is the case in mammals, prostaglandins appear to be the ultimate mediators of fever in birds, since the febrile response is attenuated when prostaglandin synthesis is inhibited. Ambient temperature modulates the fever response, with larger fevers at higher, and smaller fevers at lower ambient temperatures. Glucocorticoid levels are increased during fever and seem to play an important role by modulating the extent of fever generation, possibly playing a role in the attenuation of fever after repeated exposure to a pathogen in a process termed tolerance, suggesting that the fever process can be phenotypically adapted to likely future conditions. While fever has an ancient phylogenetic history and many of the underling mechanisms in birds appear similar to mammals, there are several important differences that suggest fever has evolved quite differently in these two homeothermic classes.

    Rat bite fever, caused by Streptobacillus moniliformis, is a systemic illness classically characterized by fever, rigors, and polyarthralgias. If left untreated, it carries a mortality rate of 10%. Unfortunately, its nonspecific initial presentation combined with difficulties in culturing its causative organism produces a significant risk of delay or failure in diagnosis. The increasing popularity of rats and other rodents as pets, together with the risk of invasive or fatal disease, demands increased attention to rat bite fever as a potential diagnosis. The clinical and biological features of rat bite fever and Streptobacillus moniliformis are reviewed, providing some distinguishing features to assist the clinician and microbiologist in diagnosis.

    The potential for health promotion through social networking sites (SNSs) is widely recognized. However, while health promotion prides itself in focusing on the social determinants of health, its partiality for persuading individuals to comply with health behaviours dominates the way health promotion utilizes SNSs. This paper contributes to an understanding of collaborative ways SNSs can work for health promotion agendas of self-determination and empowerment in an Indigenous Australia context. An ethnographic study was undertaken with Deadly Choices, an Indigenous-led health promotion initiative. The study involved participant observation of interactions on Deadly Choices SNSs between Deadly Choices and its online community members. Deadly Choices provides an example of SNSs providing a powerful tool to create a safe, inclusive and positive space for Indigenous people and communities to profile their healthy choices, according to Indigenous notions of health and identity. The study found five principles that underpin Deadly Choices' use of SNSs for health promotion. These are: create a dialogue; build community online and offline; incentivise healthy online engagement; celebrate Indigenous identity and culture; and prioritize partnerships. Deadly Choices SNSs empowers Indigenous people and communities to be health promoters themselves, which represents a power shift from health promotion practitioner to Indigenous people and communities and more broadly, an enactment of Indigenous self-determination on SNSs. Mainstream health promotion can learn from Indigenous health promotion practice regarding the use of SNSs for health promotion agendas. © The Author 2017. Published by Oxford University Press.

    African swine fever (ASF) is a notifiable infectious disease with a high impact on swine health. The disease is endemic in certain regions in the Baltic countries and has spread to Poland constituting a risk of ASF spread toward Western Europe. Therefore, as part of contingency planning, it is important to explore strategies that can effectively control an epidemic of ASF. In this study, the epidemiological and economic effects of strategies to control the spread of ASF between domestic swine herds were examined using a published model (DTU-DADS-ASF). The control strategies were the basic EU and national strategy (Basic), the basic strategy plus pre-emptive depopulation of neighboring swine herds, and intensive surveillance of herds in the control zones, including testing live or dead animals. Virus spread via wild boar was not modelled. Under the basic control strategy, the median epidemic duration was predicted to be 21days (5th and 95th percentiles; 1-55days), the median number of infected herds was predicted to be 3 herds (1-8), and the total costs were predicted to be €326 million (€256-€442 million). Adding pre-emptive depopulation or intensive surveillance by testing live animals resulted in marginal improvements to the control of the epidemics. However, adding testing of dead animals in the protection and surveillance zones was predicted to be the optimal control scenario for an ASF epidemic in industrialized swine populations without contact to wild boar. This optimal scenario reduced the epidemic duration to 9days (1-38) and the total costs to €294 million (€257-€392 million). Export losses were the driving force of the total costs of the epidemics.

Amidst a particularly dangerous moment, the show’s hero references the human struggle to survive by remarking, “We are the walking dead.” This offhand comment sheds light upon physicians’ struggles in medicine, in particular the high prevalence of burnout and the challenge to cultivate compassion and meaning. This is an important question for our age and for our profession. Are we the walking dead? PMID:28376445

    Fever is a benign process, but it is still frequently regarded as harmful. We aimed to evaluate the knowledge of parents and healthcare professionals on fever. Data were obtained through questionnaires administered to a sample of parents and nurses in the paediatric emergency rooms of two hospitals and to family doctors and paediatricians currently practising in Portugal. We collected 265 answers from parents, 49 from nurses and 525 from doctors. Most nurses (74%), doctors (55%) and parents (43%) considered fever as a temperature above 38°C. The parents' first reaction to a febrile child was to give them antipyretics, and acetaminophen was used most frequently (44%). Nurses considered that a child with fever must always be treated and that a history of febrile seizures was the most decisive factor in initiating treatment. On the other hand, the most important factor for paediatricians was the presence of discomfort. For parents (74%) and nurses (92%), the most feared effect of untreated fever was seizures, and for paediatricians (97%), it was irritability. The parents' and nurses' attitudes demonstrated fear of fever and its consequences. The approach to paediatric fever was significantly different among healthcare professionals. ©2016 Foundation Acta Paediatrica. Published by John Wiley & Sons Ltd.

  2. Vertical Mixing in the Dead Sea

    For hundreds of years, the Dead Sea was characterized by a stable haline stratification, supported by runoff. The penetration of the winter convection was limited to an upper mixed layer (UML) of about 30-50 m. Below the UML, a stable halocline prevented the mixing. As a result of the runoff reduction, the UML salinity increased and the gravitational stability diminished. During the winter of 1978-1979, the sea water overturned, ending the long-term stable hydrological regime. Since 1979, the haline stratification structure reoccurred twice after extremely rainy winters, in 1980-82 and 1992-1995. In other years, the sea was entirely mixed by winter thermal convection ( which occurs from November to March ) and had a seasonal pycnocline beneath the UML during summer. Profiles of temperature and quasi-salinity (density anomaly from 1000 kg/m3 for the chosen reference temperature of 32° C) during the last 19 years, show the formation of summer ``overturning halocline'' beneath the UML, and the thermocline that supports the stable stratification. Another warm and saline layer is formed also during the summer period near the bottom. This layer spreads from the southern part of the sea, where end-brine is discharged to the sea from the Israeli and Jordanian salt plants' evaporation ponds. The end-brine has extremely high salinity (˜ 350 g/kg) and, in spite of the high temperatures ( ˜ 45° C), high density (1350 kg/m^3), it therefore spreads as a gravitational current in the Dead Sea deep basin. Estimation of the density ratio (Rρ) for the Dead Sea water (where measurements of water salinity is quite difficult) was done using quasi-salinity (σ32) and potential temperature (θ): Rρ= [α(partialθ/partial z)]/[β(partial σ32/partial z)], where α and β are temperature expansion and quasi-salinity contraction coefficients respectively. The values of α and β for the Dead Sea water were defined from water samples collected during 2008. The Rρ values confirm that

  4. Dead Zone Accretion Flows in Protostellar Disks

    Planets form inside protostellar disks in a dead zone where the electrical resistivity of the gas is too high for magnetic forces to drive turbulence. We show that much of the dead zone nevertheless is active and flows toward the star while smooth, large-scale magnetic fields transfer the orbital angular momentum radially outward. Stellar X-ray and radionuclide ionization sustain a weak coupling of the dead zone gas to the magnetic fields, despite the rapid recombination of free charges on dust grains. Net radial magnetic fields are generated in the magnetorotational turbulence in the electrically conducting top and bottom surface layers of the disk, and reach the midplane by ohmic diffusion. A toroidal component to the fields is produced near the midplane by the orbital shear. The process is similar to the magnetization of the solar tachocline. The result is a laminar, magnetically driven accretion flow in the region where the planets form.

    One purpose of this review was to raise awareness for the new autoinflammatory syndromes. These diseases are increasingly recognized and are in the differential diagnosis of many disease states. We also aimed to review the latest recommendations for the diagnosis, management, and treatment of these patients. Familial Mediterranean fever (FMF), cryopyrin-associated periodic syndrome (CAPS), tumor necrosis factor receptor-associated periodic fever syndrome (TRAPS), and hyperimmunoglobulinemia D and periodic fever syndrome/mevalonate kinase deficiency (HIDS/MVKD) are the more common autoinflammatory diseases that are characterized by periodic fevers and attacks of inflammation. Recently much collaborative work has been done to understand the characteristics of these patients and to develop recommendations to guide the physicians in the care of these patients. These recent recommendations will be summarized for all four diseases. FMF is the most common periodic fever disease. We need to further understand the pathogenesis and the role of single mutations in the disease. Recently, the management and treatment of the disease have been nicely reviewed. CAPS is another interesting disease associated with severe complications. Anti-interleukin-1 (anti-IL-1) treatment provides cure for these patients. TRAPS is characterized by the longest delay in diagnosis; thus, both pediatricians and internists should be aware of the characteristic features and the follow-up of these patients. HIDS/MVKD is another autoinflammatory diseases characterized with fever attacks. The spectrum of disease manifestation is rather large in this disease, and we need further research on biomarkers for the optimal management of these patients.

    Posttraumatic stress disorder (PTSD) in response to active war is understudied among Sinhalese children in Sri Lanka. We investigated PTSD symptom severity in children using child (n = 60) and mother (n = 60) reports; child-reported war exposure and coping; as well as self-reported maternal PTSD symptom severity. The study addressed active war in 2 rural locations (acute and chronic community war exposure). Child-reports were significantly greater than mother-reports of child PTSD symptom severity. Furthermore, children's war exposure, child-reported and mother-reported child PTSD symptom severity, and maternal PTSD symptom severity were significantly greater in the acute versus chronic community war exposure location, but children's approach and avoidance coping did not significantly differ, indicating a potential ceiling effect. Children's war exposure significantly, positively predicted child-reported child PTSD symptom severity, controlling for age, gender, and maternal PTSD symptom severity, but only maternal PTSD symptom severity significantly, positively predicted mother-reported child PTSD symptom severity. Avoidance coping (in both acute and chronic war) significantly positively mediated the children's war exposure-child-reported child PTSD symptom severity relation, but not mother-reports of the same. Approach coping (in chronic but not acute war) significantly, positively mediated the children's war exposure-child-reported and mother-reported child PTSD symptom severity relations. We advanced the literature on long-term active war by confirming the value of children's self-reports, establishing that both approach and avoidance coping positively mediated the war-exposure-PTSD symptom severity relation, and that the mediation effect of approach coping was situationally moderated by acute verses chronic community war exposure among Sri Lankan children.

    Highly evaporated Dead Sea brines are found in isolated sinkholes along the Dead Sea. Many of these brines reach densities of over 1.3 kg/L and pH<5 and are the product of evaporation of Dead Sea brine that drain into the sinkholes. The low pH and the reddish to brownish hue of these brines were an enigma until recently. Despite the rather high total alkalinity (TA) of the Dead Sea (3.826 mmol/kg) the pH of the Dead Sea brine is known to be slightly acidic with a value of ~6.3. In comparison, seawater with the same alkalinity would have a pH value well above 8.3, meaning that H+ activity is 100 fold lower than that of Dead Sea brine. In the present work we assess the apparent dissociation constant value of boric acid (K`B) for the Dead Sea brine and use it to explain the brine's low pH value. We then show that pH decreases further as the brine evaporates and salinity increases. Finally we explain the reddish hue of the hypersaline brines in the sinkholes as due to the presence of dissolved bromine. The latter is the product of oxidation of dissolved bromide, a process that is enabled by the low pH of the hypersaline brines and their high bromide concentration.

  8. The dead donor rule, voluntary active euthanasia, and capital punishment.

    We argue that the dead donor rule, which states that multiple vital organs should only be taken from dead patients, is justified neither in principle nor in practice. We use a thought experiment and a guiding assumption in the literature about the justification of moral principles to undermine the theoretical justification for the rule. We then offer two real world analogues to this thought experiment, voluntary active euthanasia and capital punishment, and argue that the moral permissibility of terminating any patient through the removal of vital organs cannot turn on whether or not the practice violates the dead donor rule. Next, we consider practical justifications for the dead donor rule. Specifically, we consider whether there are compelling reasons to promulgate the rule even though its corresponding moral principle is not theoretically justified. We argue that there are no such reasons. In fact, we argue that promulgating the rule may actually decrease public trust in organ procurement procedures and medical institutions generally - even in states that do not permit capital punishment or voluntary active euthanasia. Finally, we examine our case against the dead donor rule in the light of common arguments for it. We find that these arguments are often misplaced - they do not support the dead donor rule. Instead, they support the quite different rule that patients should not be killed for their vital organs.

    Variation of dead wood decay rates among tropical trees remains one source of uncertainty in global models of the carbon cycle. Taking advantage of a broad forest plot network surveyed for tree mortality over a 23-year period, we measured the remaining fraction of boles from 367 dead trees from 26 neotropical species widely varying in wood density (0.23-1.24 g cm(-3)) and tree circumference at death time (31.5-272.0 cm). We modeled decay rates within a Bayesian framework assuming a first order differential equation to model the decomposition process and tested for the effects of forest management (selective logging vs. unexploited), of mode of death (standing vs. downed) and of topographical levels (bottomlands vs. hillsides vs. hilltops) on wood decay rates. The general decay model predicts the observed remaining fraction of dead wood (R2 = 60%) with only two biological predictors: tree circumference at death time and wood specific density. Neither selective logging nor local topography had a differential effect on wood decay rates. Including the mode of death into the model revealed that standing dead trees decomposed faster than downed dead trees, but the gain of model accuracy remains rather marginal. Overall, these results suggest that the release of carbon from tropical dead trees to the atmosphere can be simply estimated using tree circumference at death time and wood density.

    Objective: To verify if the Bio-Manguinhos 17DD yellow fever vaccine (17DD-YFV) used in lower doses is as immunogenic and safe as the current formulation. Results: Doses from 27,476 IU to 587 IU induced similar seroconversion rates and neutralizing antibodies geometric mean titers (GMTs). Immunity of those who seroconverted to YF was maintained for 10 mo. Reactogenicity was low for all groups. Methods: Young and healthy adult males (n = 900) were recruited and randomized into 6 groups, to receive de-escalating doses of 17DD-YFV, from 27,476 IU to 31 IU. Blood samples were collected before vaccination (for neutralization tests to yellow fever, serology for dengue and clinical chemistry), 3 to 7 d after vaccination (for viremia and clinical chemistry) and 30 d after vaccination (for new yellow fever serology and clinical chemistry). Adverse events diaries were filled out by volunteers during 10 d after vaccination. Volunteers were retested for yellow fever and dengue antibodies 10 mo later. Seropositivity for dengue was found in 87.6% of volunteers before vaccination, but this had no significant influence on conclusions. Conclusion: In young healthy adults Bio-Manguinhos/Fiocruz yellow fever vaccine can be used in much lower doses than usual. International Register ISRCTN 38082350. PMID:23364472

    Dead wood is a major component of forests and contributes to overall diversity, primarily by supporting insects that feed directly on or in it. Further, a variety of organisms benefit by feeding on those insects. What is not well known is how or whether dead wood influences the composition of the arthropod community that is not solely dependent on it as a food resource, or whether woody debris influences prey available to generalist predators. One group likely to be affected by dead wood is ground-dwelling arthropods. We studied the effect of adding large dead wood to unburned and frequently burnedmore » pine stands to determine if dead wood was used more when the litter and understory plant community are removed. We also studied the effect of annual removal of dead wood from large (10-ha) plots over a 5-year period on ground-dwelling arthropods. In related studies, we examined the relationships among an endangered woodpecker that forages for prey on live trees, its prey, and dead wood in the forest. Finally, the results of these and other studies show that dead wood can influence the abundance and diversity of the ground-dwelling arthropod community and of prey available to generalist predators not foraging directly on dead trees.« less

  13. Coding for Communication Channels with Dead-Time Constraints

    2004-01-01

    Coding schemes have been designed and investigated specifically for optical and electronic data-communication channels in which information is conveyed via pulse-position modulation (PPM) subject to dead-time constraints. These schemes involve the use of error-correcting codes concatenated with codes denoted constrained codes. These codes are decoded using an interactive method. In pulse-position modulation, time is partitioned into frames of Mslots of equal duration. Each frame contains one pulsed slot (all others are non-pulsed). For a given channel, the dead-time constraints are defined as a maximum and a minimum on the allowable time between pulses. For example, if a Q-switched laser is used to transmit the pulses, then the minimum allowable dead time is the time needed to recharge the laser for the next pulse. In the case of bits recorded on a magnetic medium, the minimum allowable time between pulses depends on the recording/playback speed and the minimum distance between pulses needed to prevent interference between adjacent bits during readout. The maximum allowable dead time for a given channel is the maximum time for which it is possible to satisfy the requirement to synchronize slots. In mathematical shorthand, the dead-time constraints for a given channel are represented by the pair of integers (d,k), where d is the minimum allowable number of zeroes between ones and k is the maximum allowable number of zeroes between ones. A system of the type to which the present schemes apply is represented by a binary- input, real-valued-output channel model illustrated in the figure. At the transmitting end, information bits are first encoded by use of an error-correcting code, then further encoded by use of a constrained code. Several constrained codes for channels subject to constraints of (d,infinity) have been investigated theoretically and computationally. The baseline codes chosen for purposes of comparison were simple PPM codes characterized by M-slot PPM

    Most arid and semi-arid regions are characterized by evaporites, which are assured sources for volatile organohalogens (VOX) [1]. These compounds play an important role in tropospheric and stratospheric chemistry. The Dead Sea between Israel and Jordan is the world's most famous and biggest all-season water covered salt lake. In both countries chemical plants like the Dead Sea Works and the Arab Potash Company are located at the southern part of the Dead Sea and mine various elements such as bromine and magnesium. Conveying sea water through constructed evaporation pans multifarious salts are enriched and precipitated. In contrast, the Northern basin and main part of the Dead Sea has remained almost untouched by industrial salt production. Its fresh water supply from the Jordan River is constantly decreasing, leading to further increased salinity. During a HALOPROC campaign (Natural Halogenation Processes in the Environment) we collected various samples including air, soils, sediments, halophytic plants, ground- and seawater from the Northern and Southern basin of the Israeli side of the Dead Sea. These samples were investigated for the occurrence of halocarbons using different analytical techniques. Most samples were analyzed for volatile organohalogens such as haloalkanes using gas chromatography- mass spectrometry (GC-MS). Interestingly, there is a strong enrichment of trihalomethanes (THM), especially all chlorinated and brominated ones and also the iodinated compound dichloroiodomethane were found in the Southern basin. In addition, volatile organic carbons (VOC) such as ethene and some other alkenes were analyzed by a gas chromatography-flame ionisation detector (GC-FID) to obtain further information about potential precursors of halogenated compounds. Halophytic plants were investigated for their potential to release chloromethane and bromomethane but also for their stable carbon and hydrogen isotope composition. For this purpose, a plant chamber was

    1) Determine the correlation between pulmonary dead space fraction and extubation success in postoperative pediatric cardiac patients; and 2) document the natural history of pulmonary dead space fractions, dynamic compliance, and airway resistance during the first 72 hours postoperatively in postoperative pediatric cardiac patients. A retrospective chart review. Cardiac ICU in a quaternary care free-standing children's hospital. Twenty-nine with balanced single ventricle physiology, 61 with two ventricle physiology. None. We collected data for all pediatric patients undergoing congenital cardiac surgery over a 14-month period during the first 72 hours postoperatively as well as prior to extubation. Overall, patients with successful extubations had lower preextubation dead space fractions and shorter lengths of stay. Single ventricle patients had higher initial postoperative and preextubation dead space fractions. Two-ventricle physiology patients had higher extubation failure rates if the preextubation dead space fraction was greater than 0.5, whereas single ventricle patients had similar extubation failure rates whether preextubation dead space fractions were less than or equal to 0.5 or greater than 0.5. Additionally, increasing initial dead space fraction values predicted prolonged mechanical ventilation times. Airway resistance and dynamic compliance were similar between those with successful extubations and those who failed. Initial postoperative dead space fraction correlates with the length of mechanical ventilation in two ventricle patients but not in single ventricle patients. Lower preextubation dead space fractions are a strong predictor of successful extubation in two ventricle patients after cardiac surgery, but may not be as useful in single ventricle patients.

    The Dead Sea Region is an exceptional ecosystem whose seismic activity has influenced all facets of the development, from ground water availability to human evolution. Israelis, Palestinians and Jordanians living in the Dead Sea region are exposed to severe earthquake hazard. Repeatedly large earthquakes (e.g. 1927, magnitude 6.0; (Ambraseys, 2009)) shook the whole Dead Sea region proving that earthquake hazard knows no borders and damaging seismic events can strike anytime. Combined with the high vulnerability of cities in the region and with the enormous concentration of historical values this natural hazard results in an extreme earthquake risk. Thus, an integration of earthquake parameters at all scales (size and time) and their combination with data of infrastructure are needed with the specific aim of providing a state-of-the-art seismic hazard assessment for the Dead Sea region as well as a first quantitative estimate of vulnerability and risk. A strong motivation for our research is the lack of reliable multi-parameter ground-based geophysical information on earthquakes in the Dead Sea region. The proposed set up of a number of observatories with on-line data access will enable to derive the present-day seismicity and deformation pattern in the Dead Sea region. The first multi-parameter stations were installed in Jordan, Israel and Palestine for long-time monitoring. All partners will jointly use these locations. All stations will have an open data policy, with the Deutsches GeoForschungsZentrum (GFZ, Potsdam, Germany) providing the hard and software for real-time data transmission via satellite to Germany, where all partners can access the data via standard data protocols.

    A bottom photographic and temperature study was carried out in the Dead Sea using a miniature version of the unmanned camera system ANGUS (mini-ANGUS). Due to the low transparency of the Dead Sea water, the bottom photographs provide very poor results. Only in a very few locations was the floor visible and in those cases it was found to be a white undulating sedimentary surface. The bottom temperature measurements, which were made continuously along the ship track, indicate the presence of a large zone of temperature anomalies. This zone is located in the deep part of the north basin at a water depth of over 330 m. The anomalies occur above a portion of an east-west fault which cuts through the Dead Sea suggesting the presence of hydrothermal activity.

    Studying the evolution of a circumplanetary disk can help us to understand the formation of Jupiter and the four Galilean satellites. With the grid-based hydrodynamic code, FARGO3D, we simulate the evolution of a circumplanetary disk with a dead zone, a region of low turbulence. Tidal torques from the sun constrain the size of the circumplanetary disk to about 0.4 R_H. The dead zone provides a cold environment for icy satellite formation. However, as material builds up there, the temperature of the dead zone may reach the critical temperature required for the magnetorotational instability to drive turbulence. Part of the dead zone accretes on to the planet in an accretion outburst. We explore possible disk parameters that provide a suitable environment for satellite formation.

    Coxiella burnetii, the causative agent of Q fever, is present worldwide. Recent studies have shown that this bacterium is an emerging pathogen in French Guiana and has a high prevalence (24% of community-acquired pneumonia). In this review, we focus on the peculiar epidemiology of Q fever in French Guiana. We place it in the context of the epidemiology of the disease in the surrounding countries of South America. We also review the clinical features of Q fever in this region, which has severe initial presentation but low mortality rates. These characteristics seem to be linked to a unique genotype (genotype 17). Finally, we discuss the issue of the animal reservoir of C. burnetii in French Guiana, which is still unknown. Further studies are necessary to identify this reservoir. Identification of this reservoir will improve the understanding of the Q fever epidemic in French Guiana and will provide new tools to control this public health problem. PMID:25092817

    Analysis of the dead zone is among the intensive studies in a closed-loop fiber optic gyroscope. In a dead zone, a gyroscope cannot detect any rotation and produces a zero bias. In this study, an analysis of dead zone sources is performed in simulation and experiments. In general, the problem is mainly due to electrical cross coupling and phase modulation drift. Electrical cross coupling is caused by interference between modulation voltage and the photodetector. The cross-coupled signal produces spurious gyro bias and leads to a dead zone if it is larger than the input rate. Phase modulation drift as another dead zone source is due to the electrode contamination, the piezoelectric effect of the LiNbO3 substrate, or to organic fouling. This modulation drift lasts for a short or long period of time like a lead-lag filter response and produces gyro bias error, noise spikes, or dead zone. For a more detailed analysis, the cross-coupling effect and modulation phase drift are modeled as a filter and are simulated in both the open-loop and closed-loop modes. The sources of dead zone are more clearly analyzed in the simulation and experimental results.

    Gap filling for the reconstruction of metabolic networks is to restore the connectivity of metabolites via finding high-confidence reactions that could be missed in target organism. Current methods for gap filling either fall into the network topology or have limited capability in finding missing reactions that are indirectly related to dead-end metabolites but of biological importance to the target model. We present an automated dead-end filling (DEF) approach, which is derived from the wisdom of endosymbiosis theory, to fill gaps by finding the most efficient dead-end utilization paths in a constructed quasi-endosymbiosis model. The recalls of reactions and dead ends of DEF reach around 73% and 86%, respectively. This method is capable of finding indirectly dead-end-related reactions with biological importance for the target organism and is applicable to any given metabolic model. In the E. coli iJR904 model, for instance, about 42% of the dead-end metabolites were fixed by our proposed method. DEF is publicly available at http://bis.zju.edu.cn/DEF/. mchen@zju.edu.cn Supplementary data are available at Bioinformatics online.

    This paper presents a model for evaluating measurement uncertainty of a feature used in the assessment of ultrasound images: dead zone. The dead zone was measured by two technicians of the INMETRO's Laboratory of Ultrasound using a phantom and following the standard IEC/TS 61390. The uncertainty model was proposed based on the Guide to the Expression of Uncertainty in Measurement. For the tested equipment, results indicate a dead zone of 1.01 mm, and based on the proposed model, the expanded uncertainty was 0.17 mm. The proposed uncertainty model contributes as a novel way for metrological evaluation of diagnostic imaging by ultrasound.

    Yellow fever virus is a mosquito-borne flavivirus that causes yellow fever, an acute infectious disease that occurs in South America and sub-Saharan Africa. Most patients with yellow fever are asymptomatic, but among the 15% who develop severe illness, the case fatality rate is 20%-60%. Effective live-attenuated virus vaccines are available that protect against yellow fever (1). An outbreak of yellow fever began in Brazil in December 2016; since July 2017, cases in both humans and nonhuman primates have been reported from the states of São Paulo, Minas Gerais, and Rio de Janeiro, including cases occurring near large urban centers in these states (2). On January 16, 2018, the World Health Organization updated yellow fever vaccination recommendations for Brazil to include all persons traveling to or living in Espírito Santo, São Paulo, and Rio de Janeiro states, and certain cities in Bahia state, in addition to areas where vaccination had been recommended before the recent outbreak (3). Since January 2018, 10 travel-related cases of yellow fever, including four deaths, have been reported in international travelers returning from Brazil. None of the 10 travelers had received yellow fever vaccination.

    AIM To describe the frequency and clinical characteristics of patients with undifferentiated periodic fever (UPF) and to investigate whether a clinical classification of UPF based on the PRINTO-Eurofever score can help predicting the response to treatment and the outcome at follow-up. METHODS Clinical and therapeutic information of patients with recurrent fever who presented at a single pediatric rheumatology center from January 2006 through April 2016 were retrospectively collected. Patients with a clinical suspicion of hereditary periodic fever (HPF) syndrome and patients with clinical picture of periodic fever, aphthae, pharingitis, adenitis (PFAPA) who were refractory to tonsillectomy underwent molecular analysis of five HPF-related genes: MEFV (NM_000243.2), MVK (NM_000431.3), TNFRSF1A (NM_001065.3), NLRP3 (NM_001079821.2), NLRP12 (NM_001277126.1). All patients who had a negative genetic result were defined as UPF and further investigated. PRINTO-Eurofever score for clinical diagnosis of HPF was calculated in all cases. RESULTS Of the 221 patients evaluated for periodic fever, twelve subjects with a clinical picture of PFAPA who were refractory to tonsillectomy and 22 subjects with a clinical suspicion of HPF underwent genetic analysis. Twenty-three patients (10.4%) resulted negative and were classified as UPF. The median age at presentation of patients with UPF was 9.5 mo (IQR 4-24). Patients with UPF had a higher frequency of aphthae (52.2% vs 0%, P = 0.0026) and musculoskeletal pain (65.2% vs 18.2%, P = 0.0255) than patients with genetic confirmed HPF. Also, patients with UPF had a higher frequency of aphthous stomatitis (52.2% vs 10.7%, P < 0.0001), musculoskeletal pain (65.2% vs 8,0%, P < 0.0001), and abdominal pain (52.2% vs 4.8%, P < 0.0001) and a lower frequency of pharyngitis (56.6% vs 81.3%, P = 0.0127) compared with typical PFAPA in the same cohort. Twenty-one of 23 patients with UPF (91.3%) received steroids, being effective in 16; 13 (56.2%) were

    The surrounded area of the Dead Sea, especially the west side suffers from many hydrological problems. While the Dead Sea level drop considered a major problem that affect the quality of the surrounded freshwater resources, a lot of the surface water flood from the adjacent Wadi are lost through direct run off without any exploitation. Therefore, it is necessary to maintain a type of balance between surface water exploitation through the Wadi and at the same time allow a sufficient amount of flow to the Dead Sea to ensure its sustainability. In this study, we choose one of the larger tributaries in the western side of the Dead Sea basin. The stream was modelled for runoff response to different rainfall amount and climate conditions (dry, normal, and wet seasons) which were chosen from the rainy seasons in the previous 30 years. Finally, the amount of surface water contribution from each of the three seasons of the Dead Sea was quantified. The outcome of the model shows the results from the normal rainy season, which is frequently reoccurs and common in the region. The model data show that such events normally contribute with about 18-22 MCM annually to the Dead Sea. The problem is with the recurrence of dry season such as 2005/2006, by which the amount of the surface water decrease and consequently has adverse effect on the Dead Sea. However, the presence of less frequent thunder storm season such as that one in 1991/1992 has also a positive effect on the Dead Sea level. In the rainy season 1991/1992 there was a higher amount of rainfall over the study area that reaches around 155 MCM. Despite the presence of this high amount most of the recharge lost to the ground as groundwater recharge. The high amount of rain increases the amount of inundated surface water out of the Wadi banks and covers more surfaces all over the study area, which in role promote more water loss to the ground. That is why the total loss (rather than surface runoff) was much higher (77

  10. Never Declared Brain Dead Potential Organ Donors-An Additional Source of Donor Organs?

    2018-03-01

    Patients never declared brain dead may represent an additional source of donor organs. To determine the number of likely brain dead potential donors who are never declared brain dead and to compare them with brain dead and donation after cardiac death potential organ donors. This study was a retrospective chart review of all catastrophically brain-injured patients referred to a single-organ procurement organization (OPO) over a 4-year period. This study identified 159 likely brain dead potential organ donors, 902 brain dead potential organ donors, and 357 potential donation after circulatory death donors over a 4-year period. None. This study did not predetermine outcome measures before data collection because the study group, likely brain dead potential organ donors, had not previously been described. Likely brain dead potential donors were significantly older than brain dead potential donors ( P < .0001) but were otherwise not different demographically. They were more likely to be a late referral to the OPO ( P < .0001) and less likely to be in the donor registry ( P < .0001). The most commonly identified factors associated with a failure to declare brain death were an unwillingness to continue supportive care by the family, premention of donation, a nontimely imminent death referral, known prior objection to donation, terminal instability, and a lack of cooperation with the OPO.

    The purpose of this paper was to study the incidence and clinical significance of fever after intraventricular neuroendoscopic procedures in children. We retrospectively assessed all children subjected to an intraventricular neuroendoscopic procedure between 2004 and 2015. Body temperature 6 days postoperatively, symptoms and signs, and eventual cerebrospinal fluid analysis were evaluated. Fever was defined as temperature above 38 °C. Fifty-five children (mean age 4.8 years) had 67 procedures. Forty-three children (47 procedures, 70 %) developed fever, mostly the day of surgery (n = 17; 25 %) or the next day (n = 33; 49 %). All children who were clinically ill (n = 9, including 7 with fever) suffered serious illness, as opposed to none of the children with fever without being clinically ill (n = 36). Fever was unrelated to gender, indication for, and type of procedure and did not influence ETV success rate at 3 months. Children under 1 year less frequently developed fever (p = 0.032). Fever frequently develops after intraventricular neuroendoscopic procedures in children and follows a rather predictable course, peaking the day of surgery and/or the next day, and rapidly subsiding thereafter. Fever is not a cardinal symptom except when combined with other symptoms in children who are clinically ill (which most of them are not). Close observation avoiding invasive diagnostic tests may suffice for those who are not clinically ill, while extra attention should be paid to those whose temperature rises after day 2 especially when clinically ill, as they likely suffer serious illness. We recommend to closely observe children after any intraventricular neuroendoscopic procedure for at least 5 days.

  15. Forms of war.

    PubMed

    Vogel, H; Bartelt, D

    2007-08-01

    Under war conditions, employed weapons can be identified on radiographs obtained in X-ray diagnostic. The analysis of such X-ray films allows concluding that there are additional information about the conditions of transport and treatment; it shall be shown that there are X-ray findings which are typical and characteristic for certain forms of warfare. The radiograms have been collected during thirty years; they come from hospitals, where war casualties had been treated, and personal collections. The material is selected, because in war X-ray diagnostic will be limited and the interest of the opposing parties influence the access to the material; furthermore the possibilities to publish or to communicate facts and thoughts are different. Citizens of the USA, GB, France, or Israel will have easier access to journals than those of Vietnam, Chad, and Zimbabwe. Under war conditions, poor countries, like North Vietnam may develop own concepts of medical care. There are X-ray findings which are typical or even characteristic for air warfare, guerrilla warfare, gas war, desert warfare, conventional warfare, and annihilation warfare, and city guerrilla warfare/civil war. The examples demonstrate that weapons and the conditions of transport and treatment can be recognized by X-ray findings. The radiogram can be read like a document. In War, there are differences between a treatment and imaging diagnostic in countries, which control the air space and in those who do not. Medical care of the poor, i.e. in countries (in general those opposing the western nations) will hardly be published, and poverty has no advocate.

    ABSTRACT Lassa virus remains an important cause of illness in West Africa and among the travelers returning from this region with an acute febrile illness. The symptoms of Lassa fever can be nonspecific and mimic those of other endemic infections, especially early in illness, making a clinical diagnosis difficult; therefore, laboratory testing is needed to confirm the diagnosis. An early identification of Lassa fever is crucial for maximizing the benefit of available antiviral therapy, as treatment efficacy rapidly decreases following the clinical onset of the disease. This minireview provides an overview of the currently available diagnostic tests for Lassa fever and their strengths and weaknesses. PMID:28404674

    2008-11-01

    There has been debate in the ethics literature as to whether the donation-after-cardiac-death donor is dead after 5 minutes of absent circulation. We set out to determine whether pediatricians consider the donation-after-cardiac-death donor as dead. A survey was mailed to all 147 pediatricians who are affiliated with the university teaching children's hospital. The survey had 4 pediatric patient scenarios in which a decision was made to donate organs after 5 minutes of absent circulation. Background information described the organ shortage, and the debate about the term "irreversibility" applied to death in donation after cardiac death. Descriptive statistics were used, with responses between groups compared by using the chi(2) statistic. The response rate was 54% (80 of 147). In each scenario, when given a patient described as dead with absent circulation for 5 minutes, dead, dead," and dead. On at least 1 of the scenarios, 38 (48%) of 147 responded uncertain, disagree, or strongly disagree that the patient is definitely dead. Although the patients in the 4 scenarios were in the identical physiologic state, with absent circulation for 5 minutes, 12 (15%) of 80 respondents did not consistently consider the patients in the state called "dead" between scenarios. Fewer than 5% of respondents answered strongly agree/agree to allow donation after cardiac death while also answering disagree/strongly disagree that the patient is definitely dead, suggesting little support to abandon the dead-donor rule. Most pediatrician respondents were not confident that a donation-after-cardiac-death donor was dead. This suggests that additional debate about the concept of irreversibility applied to donation after cardiac death is needed.

    Since it has been recognized as a separate disease during the Korean war, hemorrhagic fever with renal syndrome (HFRS) has often been discovered among the members of different armies in various countries, military personnel being the highest risk group for the disease. In the period from March to May 1999 we treated 6 soldiers coming from the military formation stationed at Kosovo and Metohia. The reaction of indirect hemagglutination test proved the presence of antibodies against Hantavira in each of them. They were infected during the stay in a dugout in the area with great population of field rodents. Only one patient was slightly ill, on the admission to the hospital. The others had severe clinical and laboratory findings: several days lasting fever, strong abdominal pain, as well as the pain in the loins, dyspeptical discomfort, manifold increased blood urea nitrogen and serum creatinine values, thrombocytopenia, etc. Oliguria occurred in 4 patients. Hemorrhagic manifestations were slight (epistaxis, petechial rash, conjunctival injection), or absent. Because of the aggravation of the acute renal failure, hemodialysis was performed in 3 patients, while other 3 underwent conservative treatment. Two of the patients had severe anemia because of which transfusions of erythrocytes and plasma were performed. Complications occurred in 2 patients (convulsive crises and lung infections). All patients recovered completely.

    Deadly nightshade (Atropa belladonna) intoxication has been infrequently reported in both children and adults in the literature. In this article, the clinical and laboratory findings of 49 children with acute deadly nightshade intoxication are reviewed. Our purpose was to enlighten the findings of deadly nightshade intoxication in childhood. The most common observed symptoms and signs were meaningless speech, tachycardia, mydriasis, and flushing. None of the children required mechanical ventilation or died in our series. The patients were categorized into two groups, mild/moderate and severe intoxication. Children with and without encephalopathy were accepted as severe and mild/moderate intoxication, respectively. While 43 children were placed in the group of mild/moderate intoxication, six were in severe intoxication group. We found that meaningless speech, lethargy, and coma were more common, but tachycardia was less common in the severe intoxication group (children with encephalopathy) (P < 0.05). In the treatment, neostigmine was used in all children because of no available physostigmine in our country. In conclusion, our findings showed that the initial signs and symptoms of acute deadly nightshade intoxication might be severe in some children, but no permanent sequel and death were seen in children. We also showed that meaningless speech, lethargy, coma, and absence of tachycardia were ominous signs in deadly nightshade intoxication in childhood. Lastly, we suggest that neostigmine may be used in cases of deadly nightshade intoxication if physostigmine cannot be available.

    The Dead Sea is located on the northern branch of the African-Levant Rift systems. The rift system, according to one model, was formed by a series of strike slip faults, initially forming approximately two million years ago. The Dead Sea is an evaporite basin that receives freshwater from springs and from the Jordan River. The Dead Sea is different from other evaporite basins, such as the Great Salt Lake, in that it possesses high concentrations of magnesium and has an average pH of 6.1. The dominant cation in the Great Salt Lake is sodium, and the pH is 7.7. Calcium concentrations are also higher in the Dead Sea than in the Great Salt Lake. Both basins are similar in that the dominant anion is chlorine and the salinity levels are approximately 20 %. Other common cations that have been identified from the waters of the Dead Sea and the Great Salt Lake include sodium and potassium. A variety of Archea, Bacteria, and a single genus of a green algal, Dunaliella, has been described from the Dead Sea. Earlier studies concentrated on microbial identification and analysis of their unique physiology that allows them to survive in this type of extreme environment. Potential microbial fossilization processes, microbial fossils, and the metallic ions associated with fossilization have not been studied thoroughly. The present study is restricted to identifying probable microbial morphologies and associated metallic ions. XRD (X Ray Diffraction) analysis indicates the presence of halite, quartz, and orthoclase feldspar. In addition to these minerals, other workers have reported potassium chloride, magnesium bromide, magnesium chloride, calcium chloride, and calcium sulfate. Halite, calcium sulfate, and orthoclase were examined in this report for the presence of microbes, microbially induced deposits or microbial alteration. Neither the gypsum nor the orthoclase surfaces possesses any obvious indications of microbial life or fossilization. The sand-sized orthoclase particles are

    Lung involvement in both acute and chronic Q fever is not well described with only a few reported cases of pseudotumor or pulmonary fibrosis in chronic Q fever. The aim of this study was to better understand the pulmonary manifestations of Q fever. We conducted a retrospective cohort study of patients with diagnosis of Q fever at Mayo Clinic Rochester. A total of 69 patients were initially identified between 2001 and 2014. Thirty-eight patients were included in this study as 3 were pediatric patients, 20 did not meet serologic criteria for Q fever, and 8 did not have imaging available at time of initial diagnosis. Descriptive analysis was conducted using JMP software. The median age was 57 years [interquartile range (IQR) 43, 62], 84% from the Midwest, and 13% worked in an occupation involving animals. The most common presentation was fevers (61%). Respiratory symptoms, such as cough, were noted in only 4 patients (11%). Twelve patients (29%) had abnormal imaging studies attributed to Q fever. Three patients (25%) with acute Q fever had findings of consolidation, lymphadenopathy, pleural effusions, and nonspecific pulmonary nodules. Radiographic findings of chronic Q fever were seen in 9 patients (75%) and included consolidation, ground-glass opacities, pleural effusions, lymphadenopathy, pulmonary edema, and lung pseudotumor. Our results demonstrate that pulmonary manifestations are uncommon in Q fever but include cough and consolidation for acute Q fever and radiographic findings of pulmonary edema with pleural effusions, consolidation, and pseudotumor in those with chronic Q fever.

    To evaluate whether osteogenic matrix cell sheets can supply osteogenesis to dead bone. Femur bone fragments (5 mm in length) were obtained from Fisher 344 rats and irradiated by a single exposure of 60 Gy to produce bones that were no longer viable. Osteogenic matrix cell sheets were created from rat bone marrow-derived stromal cells (BMSCs). After wrapping the dead bone with an osteogenic matrix cell sheet, it was subcutaneously transplanted into the back of a rat and harvested after 4 weeks. Bone formation around the dead bone was evaluated by X-ray imaging and histology. Alkaline phosphatase (ALP) and osteocalcin (OC) mRNA expression levels were measured to confirm osteogenesis of the transplanted bone. The contribution of donor cells to bone formation was assessed using the Sry gene and PKH26. After the cell sheet was transplanted together with dead bone, X-ray images showed abundant calcification around the dead bone. In contrast, no newly formed bone was seen in samples that were transplanted without the cell sheet. Histological sections also showed newly formed bone around dead bone in samples transplanted with the cell sheet, whereas many empty lacunae and no newly formed bone were observed in samples transplanted without the cell sheet. ALP and OC mRNA expression levels were significantly higher in dead bones transplanted with cell sheets than in those without a cell sheet (P < 0.01). Sry gene expression and cells derived from cell sheets labeled with PKH26 were detected in samples transplanted with a cell sheet, indicating survival of donor cells after transplantation. Our study indicates that osteogenic matrix cell sheet transplantation can supply osteogenesis to dead bone. Copyright © 2018. Published by Elsevier B.V.

    Rift Valley fever (RVF) is a severe veterinary disease of livestock that also causes moderate to severe illness in people. The life cycle of RVF is complex and involves mosquitoes, livestock, people, and the environment. RVF virus is transmitted from either mosquitoes or farm animals to humans, but is generally not transmitted from person to person. People can develop different diseases after infection, including febrile illness, ocular disease, hemorrhagic fever, or encephalitis. There is a significant risk for emergence of RVF into new locations, which would affect human health and livestock industries. Copyright © 2017 Elsevier Inc. All rights reserved.

    Concepts of fever from Hippocrates to the present are briefly outlined and compared with current ideas of the pathogenesis of fever. Evidence is presented that endogenous pyrogen, the hormone that elevates body temperature, is identical with lymphocyte-activating factor, a monokine that stimulates lymphocyte proliferation and function. It now appears that inflammation and fever are closely interrelated phenomena that are modulated by a single hormone and that have been selected by evolution to protect the host against infection.

    DEAD-box RNA helicases play various, often critical, roles in all processes where RNAs are involved. Members of this family of proteins are linked to human disease, including cancer and viral infections. DEAD-box proteins contain two conserved domains that both contribute to RNA and ATP binding. Despite recent advances the molecular details of how these enzymes convert chemical energy into RNA remodeling is unknown. We present crystal structures of the isolated DEAD-domains of human DDX2A/eIF4A1, DDX2B/eIF4A2, DDX5, DDX10/DBP4, DDX18/myc-regulated DEAD-box protein, DDX20, DDX47, DDX52/ROK1, and DDX53/CAGE, and of the helicase domains of DDX25 and DDX41. Together with prior knowledge this enables a family-wide comparative structural analysis. We propose a general mechanism for opening of the RNA binding site. This analysis also provides insights into the diversity of DExD/H- proteins, with implications for understanding the functions of individual family members.

    Both endotherms and ectotherms (e.g., fish) increase their body temperature to limit pathogen infection. Ectotherms do so by moving to warmer places, hence the term "behavioral fever." We studied the manifestation of behavioral fever in the common carp infected by cyprinid herpesvirus 3, a native carp pathogen. Carp maintained at 24°C died from the infection, whereas those housed in multi-chamber tanks encompassing a 24°C-32°C gradient migrated transiently to the warmest compartment and survived as a consequence. Behavioral fever manifested only at advanced stages of infection. Consistent with this, expression of CyHV-3 ORF12, encoding a soluble decoy receptor for TNF-α, delayed the manifestation of behavioral fever and promoted CyHV-3 replication in the context of a temperature gradient. Injection of anti-TNF-α neutralizing antibodies suppressed behavioral fever, and decreased fish survival in response to infection. This study provides a unique example of how viruses have evolved to alter host behavior to increase fitness. Copyright © 2017 The Author(s). Published by Elsevier Inc. All rights reserved.

    2006-01-01

    This study examined the influence of level of practice, additional paediatric education and length of paediatric and current experience on nurses' knowledge of and beliefs about fever and fever management. Fifty-one nurses from medical wards in an Australian metropolitan paediatric hospital completed a self-report descriptive survey. Knowledge of fever management was mediocre (Mean 12.4, SD 2.18 on 20 items). Nurses practicing at a higher level and those with between one and four years paediatric or current experience were more knowledgeable than novices or more experienced nurses. Negative beliefs that would impact nursing practice were identified. Interestingly, beliefs about fever, antipyretic use in fever management and febrile seizures were similar; they were not influenced by nurses' knowledge, experience, education or level of practice. Paediatric nurses are not expert fever managers. Knowledge deficits and negative attitudes influence their practice irrespective of additional paediatric education, paediatric or current experience or level of practice. Continuing education is therefore needed for all paediatric nurses to ensure the latest clear evidence available in the literature for best practice in fever management is applied.

  5. Clinical factors and incidence of prolonged fever in neurosurgical patients.

    To describe the incidence of prolonged fever in patients admitted to the neurosurgery department, and the corresponding risk indicators. Prolonged fever was defined as a temperature higher than 38·3°C lasting more than five days. Prolonged fever is a common phenomenon and could lead to worsened outcomes in specific patient groups, especially for those with brain injury. However, the studies on prolonged fever in neurosurgical patients are limited and insufficient. A retrospective observational study. Retrospective data were collected from 1 January 2014 to 31 December 2014, at the neurosurgical department of a large teaching hospital. We performed univariate and multivariate analyses to identify independent indicators for prolonged fever vs. short-term fever. Among 2845 patients, prolonged fever occurred in 466 (16%). The older patients were associated with longer duration of mechanical ventilation and hospital stay. It predominantly occurred in patients with subarachnoid haemorrhage (SAH) and traumatic brain injury. Patients receiving antibiotic treatment tended to manifest prolonged fever more frequently. Multivariate analysis revealed that the use of antibiotics, central venous catheter and prolonged mechanical ventilation were independent risk predictors for prolonged fever. Patients diagnosed with brain tumour seemed to be not associated with prolonged fever. Prolonged fever is the common complication in neurosurgical patients. The risks of prolonged fever in patients are attributed to antibiotic therapy, use of central venous catheter and prolonged mechanical ventilation. Indicators of prolonged fever are helpful for better identification of high-risk patients and fever control. A better reveal on the epidemiology and predictable factors of prolonged fever in neurosurgical patients will provide a better understanding on those patients who are most at risk, and therefore contribute to fever control and better outcome. © 2016 John Wiley & Sons Ltd.

    2018-02-01

    To examine whether maternal fever during pregnancy is associated with reduced head circumference and risk of microcephaly at birth. A prospective study of 86,980 live-born singletons within the Danish National Birth Cohort was carried out. Self-reported maternal fever exposure was ascertained in two interviews during pregnancy and information on head circumference at birth was extracted from the Danish Medical Birth Registry. Fever in pregnancy was reported by 27% of the mothers, and we identified 3370 cases of microcephaly (head circumference less than or equal to third percentile for sex and gestational age) and 1140 cases of severe microcephaly (head circumference less than or equal to first percentile for sex and gestational age). In this study, maternal fever exposure was not associated with reduced head circumference (adjusted β = 0.03, 95% confidence intervals [CI]: 0.01-0.05), increased risk of microcephaly (odds ratio: 0.95, 95% CI: 0.88-1.03) nor severe microcephaly (odds ratio: 1.01, 95% CI: 0.88-1.15) in the offspring. These findings were consistent for increasing numbers of fever episodes, for increasing fever severity, and for exposure in both early pregnancy and midpregnancy. In this most comprehensive study to date, we found no indication that maternal fever in pregnancy is associated with small head size in the offspring. Copyright © 2017 Elsevier Inc.

    Yellow fever (YF) virtually disappeared in francophone West African countries as a result of YF mass vaccination campaigns carried out between 1940 and 1953. However, because of the failure to continue mass vaccination campaigns, a resurgence of the deadly disease in many African countries began in the early 1980s. We developed an original modeling approach to assess YF epidemic risk (vulnerability) and to prioritize the populations to be vaccinated. We chose a two-step assessment of vulnerability at district level consisting of a quantitative and qualitative assessment per country. Quantitative assessment starts with data collection on six risk factors: five risk factors associated with "exposure" to virus/vector and one with "susceptibility" of a district to YF epidemics. The multiple correspondence analysis (MCA) modeling method was specifically adapted to reduce the five exposure variables to one aggregated exposure indicator. Health districts were then projected onto a two-dimensional graph to define different levels of vulnerability. Districts are presented on risk maps for qualitative analysis in consensus groups, allowing the addition of factors, such as population migrations or vector density, that could not be included in MCA. The example of rural districts in Burkina Faso show five distinct clusters of risk profiles. Based on this assessment, 32 of 55 districts comprising over 7 million people were prioritized for preventive vaccination campaigns. This assessment of yellow fever epidemic risk at the district level includes MCA modeling and consensus group modification. MCA provides a standardized way to reduce complexity. It supports an informed public health decision-making process that empowers local stakeholders through the consensus group. This original approach can be applied to any disease with documented risk factors.

  11. Psychiatry in the Korean War: perils, PIES, and prisoners of war.

    PubMed

    Ritchie, Elspeth Cameron

    2002-11-01

    In the initial months of the Korean War, very high numbers of psychological casualties occurred among American troops, 250 per 1,000 per annum. Initially, these men were evacuated to Japan or the United States, and very few of them were returned to duty. Then the principles of early and far-forward treatment, learned in the previous world wars, were reinstituted. Up to 80% of neuropsychiatric casualties were returned to duty. During and after the war, the prisoners of war were believed to have been "brainwashed," have "give-it-upitis," and exhibit apathy and depression. Mistakenly believed to be signs of moral decay, the psychiatric symptoms during and after release were probably a result of extended inhumane treatment and vitamin deficiencies.

  12. Simplifying study of fever's dramatic relief of autistic behavior.

    PubMed

    Good, Peter

    2017-02-01

    Dramatic relief of autistic behavior by infectious fever continues to tantalize parents and practitioners, yet researchers still hesitate to study its physiology/biochemistry, fearing stress and heat of brain imaging, contagion, and fever's complexity. Yet what could be more revealing than a common event that virtually 'normalizes' autistic behavior for a time? This paper proposes study of three simplified scenarios: (1) improvements appearing hours before fever, (2) return of autistic behavior soon after fever, (3) improvements persisting long after fever. Each scenario limits some risk - and some explanation - inviting triangulation of decisive factor(s) in relief and recurrence. Return of autistic behavior after fever may be most revealing. The complex mechanisms that generated fever have all abated; simpler cooling mechanisms prevail - how many plausible explanations can there be? The decisive factor in fever's benefit is concluded to be water drawn/carried from brain myelin and astrocytes by osmolytes glutamine and taurine released from muscles and brain; the decisive factor in return of autistic behavior after fever is return of water.

    PubMed

    Cirillo, Vincent J

    2006-01-01

    Typhoid fever was the scourge of 19th- and early 20th-century armies. During the Spanish-American War (1898) and the Anglo-Boer War (1899- 1902), typhoid killed more soldiers than enemy bullets. Walter Reed and his coworkers investigated the cause of the typhoid epidemics in the U.S. Army camps and concluded that, next to human contact, the housefly (Musca domestica) was the most active agent in the spread of the disease. British medical officers in South Africa, facing even worse typhoid epidemics, reached the same conclusion. The experiences of the American and British armies finally convinced the medical profession and public health authorities that these insects conveyed typhoid. The housefly was now seen as a health menace. Military and civilian sanitarians waged fly-eradication campaigns that prevented the housefly's access to breeding places (especially human excrement), and that protected food and drink from contamination. Currently, M. domestica is recognized as the mechanical vector of a wide variety of viral, bacterial, and protozoal pathogens. Fly control is still an important public health measure in the 21st century, especially in developing countries.

  15. Behavioral fever in newborn rabbits

    Satinoff, E.; Mcewen, G. N., Jr.; Williams, B. A.

    1976-01-01

    New Zealand white rabbit pups aged 12 to 72 hr were divided into three groups and given an intraperitoneal injection of Pseudomonas polysaccharide, a saline vehicle alone, and no treatment, respectively. The animals injected with pyrogen and maintained at an ambient temperature of 32 C for 2 hr did not develop fever. When placed in a thermally graded alleyway, the animals injected with pyrogen selected gradient positions that represented significantly higher temperatures than controls injected with saline. Further stay at selected positions for 5 min caused a considerable increase in the rectal temperature of the pyrogen-injected pups but not that of controls. The results support the hypothesis that newborn rabbits will develop a fever by behavioral means after a single injection of an exogenous pyrogen if the opportunity for thermoregulatory behavior is present. No fever develops if the pups must rely solely on internal thermoregulatory mechanisms. The behavioral system for producing a fever is mature at birth, but an adequate system of internal reflexes does not appear to develop for some days.

  16. Monoacylglycerol Lipase Regulates Fever Response

    Cyclooxygenase inhibitors such as ibuprofen have been used for decades to control fever through reducing the levels of the pyrogenic lipid transmitter prostaglandin E2 (PGE2). Historically, phospholipases have been considered to be the primary generator of the arachidonic acid (AA) precursor pool for generating PGE2 and other eicosanoids. However, recent studies have demonstrated that monoacyglycerol lipase (MAGL), through hydrolysis of the endocannabinoid 2-arachidonoylglycerol, provides a major source of AA for PGE2 synthesis in the mammalian brain under basal and neuroinflammatory states. We show here that either genetic or pharmacological ablation of MAGL leads to significantly reduced fever responses in both centrally or peripherally-administered lipopolysaccharide or interleukin-1β-induced fever models in mice. We also show that a cannabinoid CB1 receptor antagonist does not attenuate these anti-pyrogenic effects of MAGL inhibitors. Thus, much like traditional nonsteroidal anti-inflammatory drugs, MAGL inhibitors can control fever, but appear to do so through restricted control over prostaglandin production in the nervous system.

    The Dead Sea is a unique place on earth. It is located at the lowest point of the Jordan Rift valley and its water level is currently at -429 m above mean sea level (amsl). To the West the Judean Mountains (up to 1000 m amsl) and to the East the Moab mountains (up to 1300 m amsl) confine the north-south oriented valley. The whole region is located in a transition zone of semi-arid to arid climate conditions and together with the steep orography, this forms a quite complex and unique environment. The Virtual Institute DEad SEa Research Venue (DESERVE) is an international project funded by the German Helmholtz Association and was established to study coupled atmospheric, hydrological, and lithospheric processes in the changing environment of the Dead Sea. Previous studies showed that the valley's atmosphere is often governed by periodic wind systems (Bitan, 1974), but most of the studies were limited to ground measurements and could therefore not resolve the three dimensional development and evolution of these wind systems. Performed airborne measurements found three distinct layers above the Dead Sea (Levin, 2005). Two layers are directly affected by the Dead Sea and the third is the commonly observed marine boundary layer over Israel. In the framework of DESERVE a field campaign with the mobile observatory KITcube was conducted to study the three dimensional structure of atmospheric processes at the Dead Sea in 2014. The combination of several in-situ and remote sensing instruments allows temporally and spatially high-resolution measurements in an atmospheric volume of about 10x10x10 km3. With this data set, the development and evolution of typical local wind systems, as well as the impact of regional scale wind conditions on the valley's atmosphere could be analyzed. The frequent development of a nocturnal drainage flow with wind velocities of over 10 m s-1, the typical lake breeze during the day, its onset and vertical extension as well as strong downslope winds

    Rocky Mountain spotted fever (RMSF) is an unusual but important dermatological condition to identify without hesitation. The classic triad of headache, fever, and a rash that begins on the extremities and travels proximally to involve the trunk is found in a majority of patients. The cutaneous centripetal pattern is a result of cell to cell migration by the causative organism Rickettsia rickettsii. Such individuals should receive prompt antimicrobial therapy and supportive care to avoid serious and potentially fatal complications.

    Q fever is a global zoonosis that can cause both acute and chronic infections in humans through aerogenic transmission. Although Q fever was discovered already 80 years ago, this infectious disease remains largely unknown. We studied a case series in a Belgian tertiary care hospital. A laboratory and file query at our department was performed to detect patients who were newly diagnosed with Q fever from 01 January 2005 to 01 October 2014. In total, 10 acute Q fever and 5 chronic Q fever infections were identified. An aspecific flu-like illness was the prevailing manifestation of acute Q fever, while this was infective endocarditis in chronic Q fever cases. Noteworthy are the high percentage of myocarditis cases in the acute setting and one case of amyloidosis as a manifestation of chronic Q fever. No evolution from acute to chronic Q fever was noted; overall outcome for both acute and chronic Q fever was favourable with a 94% survival rate. Q fever is an infectious disease characterised by a variable clinical presentation. Detection requires correct assessment of the clinical picture in combination with a laboratory confirmation. Treatment and follow-up are intended to avoid a negative outcome.

  20. Children and war.

    Children bear disproportionate consequences of armed conflict. The 21st century continues to see patterns of children enmeshed in international violence between opposing combatant forces, as victims of terrorist warfare, and, perhaps most tragically of all, as victims of civil wars. Innocent children so often are the victims of high-energy wounding from military ordinance. They sustain high-energy tissue damage and massive burns - injuries that are not commonly seen in civilian populations. Children have also been deliberately targeted victims in genocidal civil wars in Africa in the past decade, and hundreds of thousands have been killed and maimed in the context of close-quarter, hand-to-hand assaults of great ferocity. Paediatricians serve as uniformed military surgeons and as civilian doctors in both international and civil wars, and have a significant strategic role to play as advocates for the rights and welfare of children in the context of the evolving 'Laws of War'. One chronic legacy of contemporary warfare is blast injury to children from landmines. Such blasts leave children without feet or lower limbs, with genital injuries, blindness and deafness. This pattern of injury has become one of the post-civil war syndromes encountered by all intensivists and surgeons serving in four of the world's continents. The continued advocacy for the international ban on the manufacture, commerce and military use of antipersonnel landmines is a part of all paediatricians' obligation to promote the ethos of the Laws of War. Post-traumatic stress disorder remains an undertreated legacy of children who have been trapped in the shot and shell of battle as well as those displaced as refugees. An urgent, unfocused and unmet challenge has been the increase in, and plight of, child soldiers themselves. A new class of combatant comprises these children, who also become enmeshed in the triad of anarchic civil war, light-weight weaponry and drug or alcohol addiction. The

    This paper examines the geographical impact of the British Government's wartime evacuation scheme on notified rates of two common acute childhood diseases (scarlet fever and diphtheria) in the 1470 local government districts of England and Wales, 1939-1945. Drawing on the notifications of communicable diseases collated by the General Register Office (GRO), we establish pre-war (baseline) disease rates for the 1470 districts. For the war years, techniques of binary logistic regression analysis are used to assess the associations between (a) above-baseline ('raised') disease rates in evacuation, neutral and reception districts and (b) the major phases of the evacuation scheme. The analysis demonstrates that the evacuation was temporally associated with distinct national and regional effects on notified levels of disease activity. These effects were most pronounced in the early years of the dispersal (1939-1941) and corresponded with initial levels of evacuation-related population change at the regional and district scales.

  4. The unwanted heroes: war invalids in Poland after World War I.

    This article focuses on the unique and hitherto unknown history of disabled ex-servicemen and civilians in interwar Poland. In 1914, thousands of Poles were conscripted into the Austrian, Prussian, and Russian armies and forced to fight against each other. When the war ended and Poland regained independence after more than one hundred years of partition, the fledgling government was unable to provide support for the more than three hundred thousand disabled war victims, not to mention the many civilians left injured or orphaned by the war. The vast majority of these victims were ex-servicemen of foreign armies, and were deprived of any war compensation. Neither the Polish government nor the impoverished society could meet the disabled ex-servicemen's medical and material needs; therefore, these men had to take responsibility for themselves and started cooperatives and war-invalids-owned enterprises. A social collaboration between Poland and America, rare in Europe at that time, was initiated by the Polish community in the United States to help blind ex-servicemen in Poland.

    Chronic Q fever is a persistent infection with the intracellular Gram-negative bacterium Coxiella burnetii, which can lead to complications of infected aneurysms. Matrix metalloproteinases (MMPs) cleave extracellular matrix and are involved in infections as well as aneurysms. We aimed to study the role of MMPs in the pathogenesis of chronic Q fever. We investigated gene expression of MMPs through microarray analysis and MMP production with ELISA in C. burnetii-stimulated peripheral blood mononuclear cells (PBMCs) of patients with chronic Q fever and healthy controls. Twenty single nucleotide polymorphisms (SNPs) of MMP and tissue inhibitor of MMP genes were genotyped in 139 patients with chronic Q fever and 220 controls with similar cardiovascular co-morbidity. Additionally, circulating MMPs levels in patients with chronic Q fever were compared with those in cardiovascular controls with and without a history of past Q fever. In healthy controls, the MMP pathway involving four genes (MMP1, MMP7, MMP10, MMP19) was significantly up-regulated in C. burnetii-stimulated but not in Escherichia coli lipopolysaccharide -stimulated PBMCs. Coxiella burnetii induced MMP-1 and MMP-9 production in PBMCs of healthy individuals (both p<0.001), individuals with past Q fever (p<0.05, p<0.01, respectively) and of patients with chronic Q fever (both p<0.001). SNPs in MMP7 (rs11568810) (p<0.05) and MMP9 (rs17576) (p<0.05) were more common in patients with chronic Q fever. Circulating MMP-7 serum levels were higher in patients with chronic Q fever (median 33.5 ng/mL, interquartile range 22.3-45.7 ng/mL) than controls (20.6 ng/mL, 15.9-33.8 ng/mL). Coxiella burnetii-induced MMP production may contribute to the development of chronic Q fever. Copyright © 2017 European Society of Clinical Microbiology and Infectious Diseases.

    This article discusses the methods the United States Holocaust Memorial Museum used to make an exhibition on the complex history of Nazi eugenics accessible to the museum's mass public and at the same time, provocative for special audiences consisting of professionals and students from the biomedical fields. Deadly Medicine: Creating the Master Race showed how both eugenics and related "euthanasia" programs in Nazi Germany helped pave the road to the Holocaust. The exhibition implicitly evoked the present-day appeal of biological explanations for human behavior and of new visions of human perfection. Educational programs used the exhibition as a springboard for discussions of bioethics and medical ethics.

    2004-04-01

    Yellow fever (YF) is a mosquito-borne viral illness that causes hemorrhagic fever in tropical Africa and South America. Although a very safe and efficient vaccine (17D) is available, it is underused. An estimated 200,000 people are still infected annually, and YF remains a major public health concern. This article reviews the recent data on YF epidemiology, virology, and immunity, and analyzes the rare postvaccination adverse effects that have been recently reported. YF vaccine should be included in the expanded program of immunization for children and sustained for people living in or traveling to endemic areas. A surveillance of vaccinated people also should be reinforced. New research programs should be developed to identify molecular markers of YF virus tropism and attenuation, and to understand mechanisms of host responses to virus infection.

    Background Pontiac fever is usually described in epidemic settings. Detection of Pontiac fever is a marker of an environmental contamination by Legionella and should thereby call for prevention measures in order to prevent outbreak of Legionnaire's disease. The objective of this study is to propose an operational definition of Pontiac fever that is amenable to epidemiological surveillance and investigation in a non epidemic setting. Methods A population of 560 elderly subjects residing in 25 nursing homes was followed during 4 months in order to assess the daily incidence of symptoms associated, in the literature, with Pontiac fever. The water and aerosol of one to 8 showers by nursing home were characterized combining conventional bacterial culture of Legionella and the Fluorescence In Situ Hybridization (FISH) technique that used oligonucleotides probes specific for Legionellaceae. A definition of Pontiac fever was devised based on clinical symptoms described in epidemic investigations and on their timing after the exposure event. The association between incidence of Pontiac fever and shower contamination levels was evaluated to test the relevance of this definition. Results The proposed definition of Pontiac fever associated the following criteria: occurrence of at least one symptom among headache, myalgia, fever and shivers, possibly associated with other 'minor' symptoms, within three days after a shower contaminated by Legionella, during a maximum of 8 days (minimum 2 days). 23 such cases occurred during the study (incidence rate: 0.125 cases per person-year [95% CI: 0.122–0.127]). A concentration of Legionella in water equal to or greater than 104.L-1 (FISH method) was associated with a significant increase of incidence of Pontiac fever (p = 0.04). Conclusion Once validated in other settings, the proposed definition of Pontiac fever might be used to develop epidemiological surveillance and help draw attention on sources of Legionella.

    2013-01-01

    DEAD-box helicases perform diverse cellular functions in virtually all steps of RNA metabolism from Bacteria to Humans. Although DEAD-box helicases share a highly conserved core domain, the enzymes catalyze a wide range of biochemical reactions. In addition to the well established RNA unwinding and corresponding ATPase activities, DEAD-box helicases promote duplex formation and displace proteins from RNA. They can also function as assembly platforms for larger ribonucleoprotein complexes, and as metabolite sensors. This review aims to provide a perspective on the diverse biochemical features of DEAD-box helicases and connections to structural information. We discuss these data in the context of a model that views the enzymes as integrators of RNA, nucleotide, and protein binding. PMID:23416748

    Intravenous administration of bacterial endotoxins in dogs is followed within 2 hours by the appearance of a fever-producing substance in the blood. This endogenous pyrogen differs from the endotoxins originally administered by its ability to produce fever in tolerant recipients and failure to promote tolerance after repeated daily injections. Endogenous serum pyrogen is destroyed by heating at 90°C. for 30 minutes, and is also inactivated to some degree by incubation at 37°C. for 24 hours. Suppression of fever by aminopyrine does not affect appearance of the endogenous factor. Animals made febrile with dinitrophenol, kaolin, or lysergic acid do not elaborate a fever-promoting substance in the blood. Sterile abscesses, accompanied by elevations in body temperature of the host, are unassociated with detectable amounts of secondary pyrogen in the serum. The absence of endogenous pyrogen in the blood of febrile dogs made leukopenic with nitrogen mustard favors the idea that polymorphonuclear leukocytes injured by endotoxins release the endogenous factor. On the other hand, the finding that the granulocytopenic animals are febrile when no circulating endogenous pyrogen is present, casts doubt upon the essential role of this substance in endotoxin fever.

    The Crimean-Congo hemorrhagic fever is a zoonotic disease transmitted by ticks and is characterized by fever and bleeding. It was seen for the first time in the south of present day Ukraine and thus named, Crimean fever. 1 In 1956, the virus was isolated in a patient with similar symptoms residing in Congo, Kenya and the virus was named Congo virus. The viruses causing these two diseases were the same and hence was termed Crimean-Congo hemorrhagic fever virus (CCHFV). Humans are the only known host that develops disease.

    Typhoid fever is an important cause of morbidity and mortality in patients especially in developing country. Therapy with conventional drugs is associated with increasing resistance, non-compliance to therapy and toxicity. Oral fluoroquinolones have been shown to be effective compared to parenteral broad-spectrum cephalosporins in the treatment of uncomplicated typhoid. However, there is no data available regarding the use of levofloxacin in the treatment of typhoid fever in spite of the susceptibility of Salmonella species to levofloxacin. The present study was undertaken to evaluate the efficacy, safety and tolerability of oral levofloxacin 750 mg once daily in the treatment of typhoid fever. Results indicated that levofloxacin 750 mg administered orally once daily was an effective, safe, well-tolerated and cost-effective option in the treatment of typhoid fever in adult Indian males and non-pregnant females.

    Further studies have been made of a pyrogenic substance which appears in the circulation of rabbits during the course of experimental fever induced by injection of typhoid vaccine. With the use of a passive transfer method and pyrogen-tolerant recipients, the biological properties of this substance have been differentiated from those of the uncleared vaccine in the circulation. The newly identified factor resembles leucocytic pyrogen in the rapidity with which it produces fever and in its failure to exhibit cross-tolerance with bacterial pyrogen. This striking similarity of properties suggests that the circulating factor is of endogenous origin and may arise from cell injury. A close correlation between its presence in the circulation and the existence of fever has been demonstrated. The possible relationship of these findings to the pathogenesis of fever is evident.

    Previously, we reported on the use of emergency tourniquets to stop bleeding in war casualties, but virtually all the data were from adults. Because no pediatric-specific cohort of casualties receiving emergency tourniquets existed, we aimed to fill knowledge gaps on the care and outcomes of this group by surveying data from a trauma registry to refine device designs and clinical training. A retrospective review of data from a trauma registry yielded an observational cohort of 88 pediatric casualties at US military hospitals in theater on whom tourniquets were used from May 17, 2003, to December 25, 2009. Of the 88 casualties in the study group, 72 were male and 16 were female patients. Ages averaged 11 years (median, 11 years; range, 4-17 years). There were 7 dead and 81 survivor outcomes for a trauma survival rate of 93%. Survivor and dead casualties were similar in all independent variables measured except hospital stay duration (median, 5 days and 1 day, respectively). Six casualties (7%) had neither extremity nor external injury in that they had no lesion indicating tourniquet use. The survival rate of the present study's casualties is similar to that of 3 recent large nonpediatric-specific studies. Although current emergency tourniquets were ostensibly designed for modern adult soldiers, tourniquet makers, perhaps unknowingly, produced tourniquets that fit children. The rate of unindicated tourniquets, 7%, implied that potential users need better diagnostic training. Level 4; case series, therapeutic study.

    2014-04-01

    Fever is common in the ICU among patients with severe brain injury. Fever has been consistently shown to exacerbate brain injuries in animal models and has been consistently associated with poor outcome in human studies. However, whether fever control improves outcome and the ideal means of fever control remain unknown. This review will address recent literature on the impact of fever on severe brain injury and on interventions to maintain normothermia. Current guidelines generally recommend maintenance of normothermia after brain injury but have scant recommendations on methods to do this. Observational trials have continued to demonstrate the association between fever and poor outcome after severe brain injury. Recent trials have shown the efficacy of more aggressive approaches to fever reduction, whereas a large randomized trial showed the relative ineffectiveness of acetaminophen alone for fever control. Several studies have also described the impact of fever and of fever control on brain physiology. The value of therapeutic normothermia in the neurocritical care unit (NCCU) is increasingly accepted, yet prospective trials that demonstrate a functional benefit to patients are lacking.

    Five suspected cases of yellow fever vaccine-associated viscerotropic disease (YEL-AVD) clustered in space and time following a vaccination campaign in Ica, Peru in 2007. All five people received the same lot of 17DD live attenuated yellow fever vaccine before their illness; four of the five died of confirmed YEL-AVD. The surviving case was classified as probable YEL-AVD. Intensive investigation yielded no abnormalities of the implicated vaccine lot and no common risk factors. This is the first described space-time cluster of yellow fever viscerotropic disease involving more than two cases. Mass yellow fever vaccination should be avoided in areas that present extremely low risk of yellow fever.

    2012-07-01

    There is a paucity of knowledge on gene expression in dead bacterial cells. Why would this knowledge be useful? The cells are dead. However, the time duration of gene expression following cell death is often unknown, and possibly in the order of minutes. In addition, it is a challenge to determine if bacterial cells are dead, or viable but non-culturable (VBNC), and what is an agreed upon correct definition of dead bacteria. Cells in the bacterial population or community may die at different rates or times and this complicates both the viability and gene expression analysis. In this article, the definition of dead bacterial cells is discussed and its significance in continued gene expression in cells following death. The definition of living and dead has implications for possible, completely, synthetic bacterial cells that may be capable of growth and division. Copyright © 2012 Elsevier B.V. All rights reserved.

The Combined Military Hospital, Malir Cantt., Karachi, from August 2005 to December 2006. All patients with age above 14 years, who were either hospitalized or treated in medical outdoor clinic due to acute febrile illness, were evaluated for clinical features of Dengue Fever (DF), Dengue haemorrhagic fever (DHF) and Dengue Shock Syndrome (DSS). Patients showing typical clinical features and haematological findings suggestive of Dengue fever (As per WHO criteria) were evaluated in detail for comparison of probable and confirmed cases of Dengue fever. All other cases of acute febrile illness, not showing clinical features or haematological abnormalities of Dengue fever, were excluded. The clinical and laboratory features were recorded on SPSS 11.0 programme and graded where required, for descriptive and statistical analysis. Out of 5200 patients with febrile illness, 107(2%) presented with typical features of DF, 40/107(37%) were Dengue-proven while 67/107(63%) were Dengue-probable. Out of Dengue-proven cases, 38 were of DF and 2 were of DHF. Day 1 temperature ranged from 99-1050C (mean 1010C). Chills and rigors were noticed in 86 (80%), myalgia in 67%, headache in 54%, pharyngitis in 35%, rash in 28%, and bleeding manifestations in 2% cases. Hepatomegaly in 1(0.5%), lymphadenopathy in 1(0.5%) and splenomegaly in 12 (11.2%) cases. Leucopoenia (count<4x109 /L) was noted in 73%, platelet count<150 x109 /L in 84% and ALT>40 U/L in 57% cases. Frequency of clinically suspected dengue virus infection was 107 (2%), while confirmed dengue fever cases were 40 (0.8%) out of 5200 fever cases. Fever with chills and rigors, body aches, headache, myalgia, rash, haemorrhagic manifestations, platelet count, total leukocyte count, and ALT, are parameters to screen the cases of suspected dengue virus

    Although body temperature is one of four key vital signs routinely monitored and treated in clinical practice, relatively little is known about the symptoms associated with febrile states. The purpose of this study was to assess the validity, reliability and feasibility of the Fever Assessment Tool (FAST) in an acute care research setting. Qualitative: To assess content validity and finalize the FAST instrument, 12 adults from an inpatient medical-surgical unit at the National Institutes of Health (NIH) Clinical Center participated in cognitive interviews within approximately 12 h of a febrile state (tympanic temperature ≥ 38° Celsius). Quantitative: To test reliability, validity and feasibility, 56 new adult inpatients completed the 21-item FAST. The cognitive interviews clarified and validated the content of the final 21-item FAST. Fifty-six patients completed the FAST from two to 133 times during routine vital sign assessment, yielding 1,699 temperature time points. Thirty-four percent of the patients (N = 19) experienced fever at one or more time points, with a total of 125 febrile time points. Kuder-Richardson 20 (KR-20) reliability of the FAST was 0.70. Four nonspecific symptom categories, Tired or Run-Down (12), Sleepy (13), Weak or Lacking Energy (11), and Thirsty (9) were among the most frequently reported symptoms in all participants. Using Generalized Estimating Equations (GEE), the odds of reporting eight symptoms, Warm (4), Sweating (5), Thirsty (9), General Body Aches (10), Weak or Lacking Energy (11), Tired or Run Down (12) and Difficulty Breathing (17), were increased when patients had a fever (Fever Now), compared to the two other subgroups-patients who had a fever, but not at that particular time point, (Fever Not Now) and patients who never had a fever (Fever Never). Many, but not all, of the comparisons were significant in both groups. Results suggest the FAST is reliable, valid and easy to administer. In addition to symptoms usually

    Hundreds of thousands of soldiers face exposure to combat during wars across the globe. The health effects of traumatic war experiences have not been adequately assessed across the lifetime of these veterans. To identify the role of traumatic war experiences in predicting postwar nervous and physical disease and mortality using archival data from military and medical records of veterans from the Civil War. An archival examination of military and medical records of Civil War veterans was conducted. Degree of trauma experienced (prisoner-of-war experience, percentage of company killed, being wounded, and early age at enlistment), signs of lifetime physician-diagnosed disease, and age at death were recorded. The US Pension Board surgeons conducted standardized medical examinations of Civil War veterans over their postwar lifetimes. Military records of 17,700 Civil War veterans were matched to postwar medical records. Signs of physician-diagnosed disease, including cardiac, gastrointestinal, and nervous disease; number of unique ailments within each disease; and mortality. Military trauma was related to signs of disease and mortality. A greater percentage of company killed was associated with signs of postwar cardiac and gastrointestinal disease (incidence risk ratio [IRR], 1.34; P < .02), comorbid nervous and physical disease (IRR, 1.51; P < .005), and more unique ailments within each disease (IRR, 1.14; P < .005). Younger soldiers (<18 years), compared with older enlistees (>30 years), showed a higher mortality risk (hazard ratio, 1.52), signs of comorbid nervous and physical disease (IRR, 1.93), and more unique ailments within each disease (IRR, 1.32) (P < .005 for all), controlling for time lived and other covariates. Greater exposure to death of military comrades and younger exposure to war trauma were associated with increased signs of physician-diagnosed cardiac, gastrointestinal, and nervous disease and more unique disease ailments across the life of Civil War

  4. Management of Postoperative Fever in Adult Cardiac Surgical Patients.

    PubMed

    O'Mara, Susan K

    Postoperative fever after cardiac surgery is a common occurrence. Most fevers are benign and self-limiting resulting from inflammation caused by surgical trauma and blood contact with cardiopulmonary bypass circuit resulting in the release of cytokines. Only a small percentage of time is postoperative fever due to an infection complicating surgery. The presence of fever frequently triggers a battery of diagnostic tests that are costly, could expose the patient to unnecessary risks, and can produce misleading or inconclusive results. It is therefore important that fever be evaluated in a systematic, prudent, clinically appropriate, and cost-effective manner. This article focuses on the current evidence regarding pathophysiology, incidence, causes, evaluation, and management of fever in postoperative adult cardiac surgical patients.

    2017-12-01

    Recent studies have shown that normal subjects exhibit periodic breathing when submitted to concomitant environmental (hypoxia) and physiological (exercise) stresses. A mathematical model including mass balance equations confirmed the short period of ventilatory oscillations and pointed out an important role of dead space in the genesis of these phenomena. Ten healthy subjects performed mild exercise on a cycloergometer in different conditions: rest/exercise, normoxia/hypoxia and no added dead space/added dead space (aDS). Ventilatory oscillations (V˙E peak power) were augmented by exercise, hypoxia and aDS (P<0.001, P<0.001 and P<0.01, respectively) whereas V˙E period was only shortened by exercise (P<0.001), with an 11-s period. aDS also increased V˙E (P<0.001), tidal volume (VT, P<0.001), and slightly augmented PETCO 2 (P<0.05) and the respiratory frequency (P<0.05). These results confirmed our previous model, showing an exacerbation of breathing instability by increasing dead space. This underlines opposite effects observed in heart failure patients and normal subjects, in which added dead space drastically reduced periodic breathing and sleep apneas. It also points out that alveolar ventilation remains very close to metabolic needs and is not affected by an added dead space. Clinical Trial reg. n°: NCT02201875. Copyright © 2017 Elsevier B.V.

    During the Second World War, publicly employed medical officers in Norway were given a role which disharmonized in many ways with the role they had before 9 April 1940. They had been employed on terms which included loyalty towards employer, colleagues and patients. After the outbreak of the war and for five years to come, loyalties were put to the test. At the same time their actual services became more demanding. Their daily work was complicated by various laws and regulations, and the political situation in general hindered personal and professional development and free communication between doctors and patients, and between colleagues. After the war the central medical administration was relentless and the sanctions against those who had supported the occupying powers were exceptionally hard. The author emphasizes the doctors' personal experiences during the war and the first postwar years. The most important sources are personal testimonies, as they come forth in public records, biographies and interviews.

  9. "War dysentery" and the limitations of German military hygiene during World War I.

    Linton, Derek S

    2010-01-01

    This article examines major epidemics of bacillary dysentery in the German army as well as among civilians in eastern Europe and in Germany during World War I. These epidemics were all the more surprising in light of prewar advances in understanding the disease and limiting dysentery outbreaks. Three major reasons are adduced for the incapacity of German military hygienists to prevent wartime epidemics. First was the difficulty of bacteriological testing at the front, especially early in the war, with negative consequences for diagnosis, therapy, and disease control. Second was inadequate hygiene including major shortcomings in latrine cleanliness and attempts to grapple with the "fly plague." Third was the lack of a Pasteur-type vaccine until late in the war. Susceptibility to dysentery was also heightened by war-related nutritional deficiencies. Taking off from an article by the English medical historian Roger Cooter, this article shows that the concept of "war dysentery" was socially constructed and served a variety of professional interests but at the same time takes issue with Cooter's arguments against linking "war" and "epidemics" pathogenetically.

    2009-11-01

    Rocky Mountain spotted fever is caused by the tick-borne bacterium Rickettsia rickettsii. Symptoms range from moderate illness to severe illness, including cardiovascular compromise, coma and death. The disease is prevalent in most of the USA, especially during warmer months. The trademark presentation is fever and rash with a history of tick bite, although tick exposure is unappreciated in over a third of cases. Other signature symptoms include headache and abdominal pain. The antibiotic therapy of choice for R. rickettsii infection is doxycycline. Preventive measures for Rocky Mountain spotted fever and other tick-borne diseases include: wearing long-sleeved, light colored clothing; checking for tick attachment and removing attached ticks promptly; applying topical insect repellent; and treating clothing with permethrin.

  13. Water input requirements of the rapidly shrinking Dead Sea

    2009-05-01

    The deepest point on Earth, the Dead Sea level, has been dropping alarmingly since 1978 by 0.7 m/a on average due to the accelerating water consumption in the Jordan catchment and stood in 2008 at 420 m below sea level. In this study, a terrain model of the surface area and water volume of the Dead Sea was developed from the Shuttle Radar Topography Mission data using ArcGIS. The model shows that the lake shrinks on average by 4 km2/a in area and by 0.47 km3/a in volume, amounting to a cumulative loss of 14 km3 in the last 30 years. The receding level leaves almost annually erosional terraces, recorded here for the first time by Differential Global Positioning System field surveys. The terrace altitudes were correlated among the different profiles and dated to specific years of the lake level regression, illustrating the tight correlation between the morphology of the terrace sequence and the receding lake level. Our volume-level model described here and previous work on groundwater inflow suggest that the projected Dead Sea-Red Sea channel or the Mediterranean-Dead Sea channel must have a carrying capacity of >0.9 km3/a in order to slowly re-fill the lake to its former level and to create a sustainable system of electricity generation and freshwater production by desalinization. Moreover, such a channel will maintain tourism and potash industry on both sides of the Dead Sea and reduce the natural hazard caused by the recession.

    Once again, the politically volatile Middle East and accompanying rhetoric has escalated the risk of a major nuclear exchange. Diplomatic efforts have failed to make the medical consequences of such an exchange a leading element in negotiations. The medical and academic communities share this denial. Without exaggeration, the harsh reality of the enormous consequences of an imminently conceivable nuclear war between Iran and Israel will encompass an unprecedented millions of dead and an unavoidable decline in public health and environmental devastation that would impact major populations in the Middle East for decades to come. Nuclear deterrence and the uncomfortable but real medical and public health consequences must become an integral part of a broader global health diplomacy that emphasizes health security along with poverty reduction and good governance.

    We report a case of Q fever in a man who presented with fever of 40 days duration associated with thrombocytosis. Serological and molecular analysis (polymerase chain reaction) confirmed infection with Coxiella burnetii. A field study was conducted by collecting blood samples from the patient's family and from the animals in the patient's house. The patient's wife and 2 of 13 dogs showed seroreactivity. Our data indicate that C. burnetii may be an underrecognized cause of fever in Brazil and emphasize the need for clinicians to consider Q fever in patients with a febrile illness, particularly those with a history of animal contact.

    Chronic Q fever, caused by Coxiella burnetii, has high mortality and morbidity rates if left untreated. Controversy about the diagnosis of this complex disease has emerged recently. We applied the guideline from the Dutch Q Fever Consensus Group and a set of diagnostic criteria proposed by Didier Raoult to all 284 chronic Q fever patients included in the Dutch National Chronic Q Fever Database during 2006–2012. Of the patients who had proven cases of chronic Q fever by the Dutch guideline, 46 (30.5%) would not have received a diagnosis by the alternative criteria designed by Raoult, and 14 (4.9%) would have been considered to have possible chronic Q fever. Six patients with proven chronic Q fever died of related causes. Until results from future studies are available, by which current guidelines can be modified, we believe that the Dutch literature-based consensus guideline is more sensitive and easier to use in clinical practice.

    Stressful war experiences can cause posttraumatic stress disorder (PTSD) in survivors. To what extent were the soldiers and young women of World War II affected by PTSD symptoms over the course of their lives? Do these men and women differ in the traumatic experiences and PTSD symptom severity? To investigate these questions 52 male and 20 female Germans aged 81-95 years were recruited through newspaper advertisements and notices and interviewed regarding war experiences and PTSD symptoms. Of the men 2% and 7% met the criteria for current and lifetime PTSD diagnoses, respectively, as compared to 10% and 30% of the women, respectively. Using multiple linear regression a dose-response relationship between the number of trauma types experienced and PTSD symptom severity could be demonstrated. The slope of the regression curve was steeper for women than for men. When controlling for the number of different traumatic experiences women reported a significantly higher severity of PTSD symptoms than men. It is presumed that this difference in severity of symptoms can be attributed to qualitative differences in the type of traumatic stress factors during the war. The present study provides evidence that even today people continue to be affected by PTSD symptoms due to events which occurred during World War II; therefore, during patient contact with this age group the war experiences specific to each individual need to be considered as potential moderators of symptoms.

    A sensitive method for determination of plasma unconjugated etiocholanolone by double-isotope-derivative dilution has been described. The mean values for normal subjects was 0.038±0.003 (SEM) μg/100 ml. 40 patients, 20 with familial Mediterranean fever and 20 with other diseases characterized by recurrent fever were studied. The over-all mean concentration of plasma unconjugated etiocholanolone for the patients (febrile or afebrile) was 0.101 ±0.012 μg/100 ml, significantly above that of normals. Mean plasma values for the patients while they were febrile did not differ from the mean values when they were afebrile. It is suggested that the concentration of plasma unconjugated etiocholanolone is not related to fever in these patients. PMID:4886315

    Lassa fever, an endemic zoonotic viral infection in West Africa, presents with varied symptoms including fever, vomiting, retrosternal pain, abdominal pain, sore-throat, mucosal bleeding, seizures and coma. When fever and abdominal pain are the main presenting symptoms, and a diagnosis of acute abdomen is entertained, Lassa fever is rarely considered in the differential diagnosis, even in endemic areas. Rather the diagnosis of Lassa fever is suspected only after surgical intervention. Therefore, such patients often undergo unnecessary surgery with resultant delay in the commencement of ribavirin therapy. This increases morbidity and mortality and the risk of nosocomial transmission to hospital staff. We report 7 patients aged between 17 months and 40 years who had operative intervention for suspected appendicitis, perforated typhoid ileitis, intussuception and ruptured ectopic pregnancy after routine investigations. All seven were post-operatively confirmed as Lassa fever cases. Four patients died postoperatively, most before commencement of ribavirin, while the other three patients eventually recovered with appropriate antibiotic treatment including intravenous ribavirin. Surgeons working in West Africa should include Lassa fever in the differential diagnosis of acute abdomen, especially appendicitis. The presence of high grade fever, proteinuria and thrombocytopenia in patients with acute abdomen should heighten the suspicion of Lassa fever. Prolonged intra-operative bleeding should not only raise suspicion of the disease but also serve to initiate precautions to prevent nosocomial transmission.

    The Deadly Nightshade, Atropa belladonna, is a plant surrounded by myth, fear and awe. In antiquity, the Greeks and the Romans knew that it contained a deadly poison. In medieval times, it was widely used by witches, sorcerors and professional poisoners. Linnaeus later codified its remarkable properties as the genus Atropa, the Fate that slits the thin spun life and the species belladonna because of its power to dilate the pupils. In the 1830s, the pure alkaloid I-atropine was isolated from the plant. This proved to be a significant tool in the study of the autonomic nervous system leading to the identification of acetylcholine as an important neurotransmitter in mammals. When pure atropine became available, it caused a large number of deaths, whether by accident, suicide or homicide.

    Lassa fever is a rodent-borne zoonosis that clinically manifests as an acute hemorrhagic fever. It is treated using ribavarin. Surviving Lassa fever without receiving the antiviral drug ribavarin is rare. Only few cases have been documented to date. We report a case of a 59-year old female with fever who was initially thought to have acute pyelonephritis and sepsis syndrome with background malaria. Further changes in her clinical state and laboratory tests led to a suspicion of Lassa fever. However at the time her laboratory confirmatory test for Lassa fever returned, her clinical state had improved and she made full recovery without receiving ribavarin. Her close contacts showed no evidence of Lassa virus infection. This report adds to the literature on the natural history of Lassa fever; and that individuals may survive Lassa fever with conservative management of symptoms of the disease and its complications.

  9. War, famine and excess child mortality in Africa: the role of parental education.

    Civilian-targeted warfare and famine constitute two of the greatest public health challenges of our time. Both have devastated many countries in Africa. Social services, and in particular, health services, have been destroyed. Dictatorial and military governments have used the withholding of food as a political weapon to exacerbate human suffering. Under such circumstances, war and famine are expected to have catastrophic impacts on child survival. This study examines the role of parental education in reducing excess child mortality in Africa by considering Tigrai-Ethiopia, which was severely affected by famine and civil war during 1973--1991. This study uses data from the 1994 Housing and Population Census of Ethiopia and on communities' vulnerability to food crises. Child mortality levels and trends by various subgroups are estimated using indirect methods of mortality estimation techniques. A Poisson regression model is used to examine the relationship between number of children dead and parental education. Although child mortality is excessively high (about 200 deaths per 1000 births), our results show enormous variations in child mortality by parental education. Child mortality is highest among children born to illiterate mothers and illiterate fathers. Our results also show that the role of parental education in reducing child mortality is great during famine periods. In the communities devastated by war, however, its impact was significant only when the father has above primary education. CONCLUSIONS Our findings suggest that both mother's and father's education are significantly and negatively associated with child mortality, although this effect diminishes over time if the crisis is severe and prolonged. The policy implications of our study include, obviously, reducing armed conflict, addressing food security in a timely manner, and expansion of educational opportunities.

    After primary infection with Coxiella burnetii, patients may develop acute Q fever, which is a relatively mild disease. A small proportion of patients (1%-5%) develop chronic Q fever, which is accompanied by high mortality and can be manifested as infected arterial or aortic aneurysms or infected vascular prostheses. The disease can be complicated by arterial fistulas, which are often fatal if they are left untreated. We aimed to assess the cumulative incidence of arterial fistulas and mortality in patients with proven chronic Q fever. In a retrospective, observational study, the cumulative incidence of arterial fistulas (aortoenteric, aortobronchial, aortovenous, or arteriocutaneous) in patients with proven chronic Q fever (according to the Dutch Chronic Q Fever Consensus Group criteria) was assessed. Proven chronic Q fever with a vascular focus of infection was defined as a confirmed mycotic aneurysm or infected prosthesis on imaging studies or positive result of serum polymerase chain reaction for C. burnetii in the presence of an arterial aneurysm or vascular prosthesis. Of 253 patients with proven chronic Q fever, 169 patients (67%) were diagnosed with a vascular focus of infection (42 of whom had a combined vascular focus and endocarditis). In total, 26 arterial fistulas were diagnosed in 25 patients (15% of patients with a vascular focus): aortoenteric (15), aortobronchial (2), aortocaval (4), and arteriocutaneous (5) fistulas (1 patient presented with both an aortocaval and an arteriocutaneous fistula). Chronic Q fever-related mortality was 60% for patients with and 21% for patients without arterial fistula (P < .0001). Primary fistulas accounted for 42% and secondary fistulas for 58%. Of patients who underwent surgical intervention for chronic Q fever-related fistula (n = 17), nine died of chronic Q fever-related causes (53%). Of patients who did not undergo any surgical intervention (n = 8), six died of chronic Q fever-related causes (75%). The

    Despite the availability of a safe and efficacious vaccine, yellow fever (YF) remains a disease of significant public health importance, with an estimated 200,000 cases and 30,000 deaths annually. The disease is endemic in tropical regions of Africa and South America; nearly 90% of YF cases and deaths occur in Africa. It is a significant hazard to unvaccinated travelers to these endemic areas. Virus transmission occurs between humans, mosquitoes, and monkeys. The mosquito, the true reservoir of YF, is infected throughout its life, and can transmit the virus transovarially through infected eggs. Man and monkeys, on the other hand, play the role of temporary amplifiers of the virus available for mosquito infection. Recent increases in the density and distribution of the urban mosquito vector, Aedes aegypti, as well as the rise in air travel increase the risk of introduction and spread of yellow fever to North and Central America, the Caribbean, the Middle East, Asia, Australia, and Oceania. It is an acute infectious disease characterized by sudden onset with a two-phase development, separated by a short period of remission. The clinical spectrum of yellow fever varies from very mild, nonspecific, febrile illness to a fulminating, sometimes fatal disease with pathognomic features. In severe cases, jaundice, bleeding diathesis, with hepatorenal involvement are common. The case fatality rate of severe yellow fever is 50% or higher. The pathogenesis and pathophysiology of the disease are poorly understood and have not been the subject of modern clinical research. There is no specific treatment for YF, making the management of YF patients extremely problematic. YF is a zoonotic disease that cannot be eradicated, therefore instituting preventive vaccination through routine childhood vaccination in endemic countries, can significantly reduce the burden of the disease. The distinctive properties of lifelong immunity after a single dose of yellow fever vaccination are the

  18. Relationships between dead wood and arthropods in the Southeastern United States.

    DOE Office of Scientific and Technical Information (OSTI.GOV)

    Ulyshen, Michael, Darragh

    The importance of dead wood to maintaining forest diversity is now widely recognized. However, the habitat associations and sensitivities of many species associated with dead wood remain unknown, making it difficult to develop conservation plans for managed forests. The purpose of this research, conducted on the upper coastal plain of South Carolina, was to better understand the relationships between dead wood and arthropods in the southeastern United States. In a comparison of forest types, more beetle species emerged from logs collected in upland pine-dominated stands than in bottomland hardwood forests. This difference was most pronounced for Quercus nigra L., amore » species of tree uncommon in upland forests. In a comparison of wood postures, more beetle species emerged from logs than from snags, but a number of species appear to be dependent on snags including several canopy specialists. In a study of saproxylic beetle succession, species richness peaked within the first year of death and declined steadily thereafter. However, a number of species appear to be dependent on highly decayed logs, underscoring the importance of protecting wood at all stages of decay. In a study comparing litter-dwelling arthropod abundance at different distances from dead wood, arthropods were more abundant near dead wood than away from it. In another study, grounddwelling arthropods and saproxylic beetles were little affected by large-scale manipulations of dead wood in upland pine-dominated forests, possibly due to the suitability of the forests surrounding the plots.« less

    To explore what triggers an elevated body temperature of > or =40.0 degrees C in some women given misoprostol, a prostaglandin E1 analogue, for postpartum haemorrhage (PPH). Post hoc analysis. One tertiary-level hospital in Quito, Ecuador. A cohort of 58 women with a fever of above 40 degrees C following treatment with sublingual misoprostol (800 micrograms) for PPH. Side effects were documented for 163 Ecuadorian women given sublingual misoprostol to treat their PPH. Women's body temperatures were measured, and if they had a fever of > or =40.0 degrees C, measurements were taken hourly until the fever subsided. Temperature trends were analysed, and the possible physiological mechanisms by which postpartum misoprostol produces a high fever were explored. The onset, duration, peak temperatures, and treatments administered for cases with a high fever. Fifty-eight of 163 women (35.6%) treated with misoprostol experienced a fever of > or =40.0 degrees C. High fevers followed a predictable pattern, often preceded by moderate/severe shivering within 20 minutes of treatment. Body temperatures peaked 1-2 hours post-treatment, and gradually declined over 3 hours. Fevers were transient and did not lead to any hospitalisation. Baseline characteristics were comparable among women who did and did not develop a high fever, except for known previous PPH and time to placental expulsion. An unexpectedly high rate of elevated body temperature of > or =40.0 degrees C was documented in Ecuador following sublingually administered misoprostol. It is unclear why temperatures > or =40.0 degrees C occurred with a greater frequency in Ecuador than in other study populations using similar treatment regimens for PPH. Pharmacogenetic studies may shed further light on variations in individuals' responses to misoprostol.
