For example hypertension history generic trandate 100 mg overnight delivery, there was a 52% term who have an unfavourable cervix may benefit decrease in the odds for bronchopulmonary more from labour induction than other women40 arrhythmia from clonidine purchase trandate 100 mg amex. In addition blood pressure medication cough discount trandate 100 mg otc, there are supported by data derived from normotensive, longer-term considerations relevant to Caesarean rather than hypertensive pregnancies50. Cervical delivery, such as the risk of uterine rupture with ripening could be by either mechanical. Ergometrine (ergonovine maleate) is the beneficial effects of antenatal corticosteroids contraindicated in all forms of hypertensive disorder can be observed within 4 hours of the first dose77. If oxytocin is not available, considered if iatrogenic preterm birth at 34+6 safer alternative uterotonic drugs that have weeks still seems likely within the next 7 days, and significantly fewer side-effects, especially acute at least 7 days have transpired since the initial course elevations in blood pressure, are recommended19,72–76. Mode of delivery is usually driven by the usual obstetric indications, unless there is evidence of substantial fetal compromise or gestational age is <30 weeks. All women with severe pre-eclampsia or eclampsia should be delivered within 24 hours, regardless of gestational age. For women with non-severe pre-eclampsia at <24+0 weeks’ gestation, counselling should include information about delivery within days as an option. For women with non-severe pre-eclampsia at 24+0–33+6 weeks’ gestation, expectant management should be considered, but only in centres capable of caring for very preterm infants. For women with non-severe pre-eclampsia at 34+0–36+6 weeks’ gestation, expectant management is advised. For women with pre-eclampsia at 37+0 weeks’ gestation, delivery within 24 hours is recommended. There is consensus that these represent indications for delivery: (1) uncontrolled maternal hypertension; (2) maternal end-organ complications of the central nervous, cardiorespiratory, haematological, renal, or hepatic systems; or (3) stillbirth or substantial fetal compromise of abruption with maternal/fetal compromise or reversed ductus venosus A wave. For women with gestational hypertension at <34+0 weeks, expectant management is advised. For women with gestational hypertension at 34+0–36+6 weeks’, expectant management is advised. For women with gestational hypertension at 37+0 weeks’, childbirth within days should be discussed. For women with pre-existing hypertension at <34+0 weeks, expectant management is advised. For women with pre-existing hypertension at 34+0–36+6 weeks, expectant management is advised, even if women require treatment with antihypertensive therapy. For women with uncomplicated pre-existing hypertension who are otherwise well at 37+0 weeks’ gestation, childbirth should be considered at 38+0–39+6 weeks’ gestation. For women with any hypertensive disorder of pregnancy, vaginal delivery should be considered unless a Caesarean delivery is required for the usual obstetric indications. If vaginal delivery is planned and the cervix is unfavourable, then cervical ripening should be used to increase the chance of a successful vaginal delivery. At a gestational age remote from term, women with a hypertensive disorder of pregnancy with evidence of fetal compromise may benefit from delivery by emergent Caesarean. Antihypertensive treatment should be continued throughout labour and delivery to maintain systolic blood pressure at <160mmHg and diastolic blood pressure at <110mmHg. Ergometrine maleate should not be administered to women with any hypertensive disorder of pregnancy, particularly pre-eclampsia or gestational hypertension; alternative oxytocics should be considered.

In this m odule, w e w ill be discussing hypertensive Slide 1 disorders of pregnancy, including pregnancy induced hypertension and preeclam psia. W e w ill also discuss G estational Diabetes as w ell as nutrition solutions related to these issues Slide 2 W e w ill begin by discussing hypertensive disorders in pregnancy. There are at least 5 distinct categories of hypertension and related disorders that occur during pregnancy. These categories are: preeclam psia/eclam psia, chronic hypertension, preeclam psia Slide 3 superim posed upon chronic hypertension, gestational hypertension and transient hypertension. Each of these w ill be discussed individually throughout the m odule, w ith recom m endations based on best practices provided. Systolic blood pressure is m easured w hen the ventricles are contracting w hile diastolic pressure is m easured w hen the ventricles are relaxed. Chronic hypertension often exists prior to pregnancy and continues throughout pregnancy. It m ay not be noticed until the second trim ester of pregnancy if prenatal care is delayed or if w om en have suffered from prolonged nausea and vom iting or m orning sickness. If hypertension is Slide 5 diagnosed in early pregnancy and persists past 6 w eeks postpartum, it w ould be considered to be a chronic health condition. G estational hypertension is differentiated from chronic hypertension w hen it occurs for the first tim e Slide 6 during pregnancy and resolves w ithin 6-12 w eeks postpartum. If the blood pressure rem ains elevated after pregnancy, then it w ould be considered a chronic condition. The physiological stress of pregnancy can lead to transient gestational hypertension, and m ay be a risk factor for hypertension later in life. W om en w ho are at highest risk for all hypertensive disorders of pregnancy include: underw eight w om en w ho do not gain adequate w eight by the m iddle to end of the 2nd trim ester of pregnancy, w om en from low socioeconom ic status backgrounds, w hich m ay be a result of stress or other underlying health issues, and w om en that are at a high risk for hypertension due to race, ethnicity, and fam ily history of hypertension. Slide 7 G estational hypertension can precede preeclam psia and then develop into preeclam psia by 30 w eeks of pregnancy. Preeclam psia is a condition that affects several m ajor organ system s in the body including the cardiovascular and renal system s. The etiology of the disease is still unclear, but it is believed that the placenta “causes” preeclam psia. Abnorm al placentation results in reduced m aternal-fetal exchange and placental hypoxia (oxygen deprivation). This hypoxia then Slide 8 leads to several biochem ical changes w hich lead to preeclam psia. It generally occurs after the m iddle of the 2nd trim ester but can occur earlier in som e individuals. Preeclam psia is distinguished from hypertension by the presence of protein in the urine w hich is called proteinuria and does not occur w ith chronic hypertension. Protein in the urine can also occur during urinary tract infections, so it is im portant to quantify the am ount of protein in the urine and to rule out infections w hen considering the presence of preeclam psia. This is accom panied by the presence of m oderate am ounts protein in the urine (greater than. A large, sudden w eight gain that is accom panied by significant edem a Slide 9 and elevated blood pressure is indicative of preeclam psia. As preeclam psia progresses, w om en m ay experience headaches or visual problem s and occasionally gastric pain. Young prim iparous w om en have been found to be at higher risk for preeclam psia in som e, but not all, studies. These young w om en are often underw eight or are at a low socieconom ic level, w hich m akes it difficult to determ ine if it is age or other factors that convey the increased risk. G enerally the latter w ill be Slide 10 characterized by a large, rapid w eight gain, sudden increase in blood pressure and protein in the urine. M ild cases of preeclam psia m ay persist for w eeks and end in the early delivery of the infant to resolve the health issues associated w ith it. For this reason, it is im portant to treat even suspected cases of preeclam psia aggressively to prevent m aternal and fetal m orbidity and m ortality. W om en w ith preeclam psia appear to be in a state of oxidative stress prior to pregnancy and then is exacerbated by Slide 12 pregnancy. These are w om en w ho often have other risk factors for Cardiovascular and/or renal disease and are at high risk for these problem s later in life. These risk factors include: obesity, high triglycerides, pre-existing hypertension, insulin resistance, diabetes, and m etabolic syndrom. W om en w ho are hypertensive in one pregnancy are at higher risk for hypertension in another pregnancy. To m anage preeclam psia hospitalization or hom e m anagem ent are dependent on the severity. Careful m anagem ent of w om en w ith gestational hypertension or m ild pre eclam psia is w arranted and can often be delivered via hom e visits or Slide 13 frequent outpatient visits.

Currently blood pressure chart for 35 year old man cheap trandate 100 mg with visa, the rabies vaccine production plant is being finished hypertension quiz questions purchase 100mg trandate with amex, starting operation in the beginning of the second semester of 2015 pulse pressure lower than 20 cheap 100mg trandate with visa. We envision that the production of inactivated rabies/ebola virus will be very similar to blood pressure medication edema order cheap trandate that established at Butantan for the production of the human rabies vaccine blood pressure medication effect on heart rate buy trandate online from canada. Following the virus production heart attack movie review quality 100mg trandate, it is expected to collect continuously the media (supernatant) during six days (the media will be replaced to keep the initial volume). The medium containing the virus will be concentrated by tangential filtration, purified by ion exchange cromatography, and the virus will be inactivated by beta-propiolactone treatment. The vaccine can be delivered in a liquid form with an expected validity of 18 months. On the other hand, the vaccine can be lyophilized to increase the validity time (to be determined). Our current rabies production plant has the capacity to produce 8 – 9 million doses of rabies vaccine/year. They hope to obtain the first lots of antibodies within 7 months and for the vaccine within 12 months in order to initiate fase 1 clinical trial in Brazil. Total enrolment of 40 subjects was completed in December 2014, and all participants have received their injections and have completed the initial monitoring phase. This trial will be led by researchers from Guinea as part of a team that includes collaborators from a number of different countries including Canada, Norway, the United States and Mali, amongst others. Research proposals across will be solicited from a number of priority research areas, namely: Ebola biology; Ebola treatment; transmission, spread, containment and prevention of Ebola; and health system impacts of the Ebola crisis. The focus is on 1-year projects, to support research with the potential to create new knowledge, and be rapidly implemented to effect changes in practice and preparedness. This alarming situation can be reversed by a major increase in highly qualified personnel for diagnosis, epidemiology, clinical trials and socio-anthropology, backed by greatly improved laboratory and hospital facilities, and research. Apart from the Gambia, Ghana and Guinea-Bissau, all the countries that adjoin the main affected region are francophone and these in turn are contiguous with six more French ex colonies. Nearly all these countries retain strong links with France, and a range of French institutions are actively involved in health-related research. Improvement of diagnostic tools There is a need for diagnostic tools that are applicable for large-scale interventions. The objective is to strengthen diagnostic capabilities and train local laboratory staff. However, the efficacy and safety of such drugs in humans are unknown and existing supplies limited. Among those, Favipiravir (T-705) was recently approved for treatment of novel or resistant influenza in Japan and has demonstrated effectiveness in mice model infected with Ebola virus. The study will be launched in Guinea and is coordinated jointly by a Guinean and a French scientist. In parallel, we will assess the antiviral activity of favipiravir in non-human primates at different doses and at different stages of disease: preventive use, post-exposure use, and use at early clinical stages of infection. In response to the dramatic escalation of the epidemic, we joined a consortium led by the Tropical Medicine Institute in Antwerp to investigate how convalescent plasma can be produced and used in Guinea in order to treat Ebola patients. France will investigate how convalescent plasma can be produced and used in Guinea in order to treat Ebola patients, and will explore the feasibility to use plasma from blood donors in order to determine whether they could constitute a valuable source of immune plasma. A third project focused on the development of a Dendritic cell-based prophylactic and therapeutic Ebola vaccines, has been submitted to the National Research Agency. In this report, an important rate of severe persistent asthenia, arthralgia, ocular and hearing disturbance was described among the survivors. Public response to epidemics In addition to their direct impact on Public Health, epidemic crises have important social, economic and political consequences through disruption of activities that are shaped and amplified by key features of local society. Other proposals include: Several proposals have been submitted to the National Research Agency in December 2014. Results are pending A study of the characteristics and care’s trajectories of patients with suspected Ebola infection in France 24 Overview of Ebola research – March 2015 A study to exploit specimens collected from Ebola virus infected patients to gather knowledge on B and T cell immunology, biomarkers, virus evolution, virulence determinants and transmission on the virus. There are currently two promising candidate vaccines against the Ebola virus available, which are yet to be tested in humans. Clinical trial preparations are underway and an implementation is expected at the beginning of 2015. However, the cocktail is globally no longer available and the production of a few new doses takes months. There is currently a lack of concepts for rapidly developing and producing passive immune therapies. This project compares different vaccination strategies and validates the most promising ones with further experiments in Marburg. Analysing and inhibiting Ebola virus entry into host cells There are currently no antiviral drugs available against Ebola viruses. One potential mechanism of anti-Ebola virus therapy could be to inhibit its entry into target cells. In order to identify potentially highly effective antiviral drugs, this project will investigate the interaction between the virus and host cells and how it can be inhibited. The significance of these mutations for the biology of the virus and its pathogenic effects is currently totally unclear. Using chimeric mouse models to investigate Ebola virus immunity and pathogenesis Immune responses to Ebola viruses are not well understood because insufficient numbers of patient samples have been available up to now. For example, it is not known how the T cell response of patients who survive Ebola infections differs to immune responses in cases where infection was fatal. Mouse models in which the virus can replicate will be used to help investigate these questions. Systems vaccinology: Hereditary predictors of Ebola virus induced adaptive immunity There is very little data available about immune responses to Ebola virus vaccines. It is expected that investigations into the initial post-immunisation stage, in which the innate immune system triggers the acquired immune response, will deliver valuable information regarding vaccination success. Besides this, the Albert-Schweitzer Hospital in Gabon will also be conducting a phase I trial sponsored by the University of Tubingen. Investigating the filovirus transmission chain in an industrialised West African country Fruit bats are known to be the natural reservoir of Ebola virus. However, the exact route of transmission to humans is unknown, as is the question of whether other infected animals play a role in the spread of the epidemic. The project will investigate the entire possible transmission chain of Ebola viruses and other so called filoviruses with existing patient samples in Ghana a relatively well industrialised West African country without having to do elaborate field work. Minimising the risk of further Ebola virus spread 9a: Investigating a possible secondary reservoir in animals in West Africa: In this project, animals in the outbreak areas will be tested for Ebola viruses as well as for Ebola antibodies, in order to identify possible secondary reservoirs and the consequent risks. Besides being dependent on air traffic movements, the risk of transporting the virus also depends on other factors. Ebola surveillance with mobile real-time data transmission in Nigeria In past Ebola outbreaks, monitoring people who had had contact with people suffering from Ebola infections was an essential tool for containing the epidemic. However, the current outbreak has taken on a scale where such measures can only be implemented by means of very modern technology, especially under West African conditions. A new system using centrally connected mobile telephones as a steering instrument is being developed in Germany, together with Nigerian partners and due to be piloted in Nigeria. The project application is now getting updated and revised; project start-up is December 2014, with estimated vaccination start up in Guinea, February 2015. These factors compound the problem with early diagnosis required for patient containment and the tracing of case contacts. However viraemia may be often brief and/or present at a low level hence diagnosis by this methodology is not always definitive. Each test requires collection of a tube of blood, and takes on average 4 hours for completion, and is expensive (~$100). These requirements are difficult to meet in resource-constrained West African settings, thus severely limiting diagnostic capacity. Other important constrain is the time lost when transporting specimens from remote locations to limited number of laboratories. This situation also poses the risk of their deterioration during prolong transport, misplacement, and delay in diagnosis. Lost time means that infected people may remain in the community and unintentionally transmit the virus to others. Moreover, in the absence of rapid laboratory support, people with other common infectious diseases, which have similar early symptoms, may be held in an Ebola holding centres as a precautionary measure, and consequently if they were not infected when entering the centre, they may unfortunately be at increased risk of acquiring infection within this facility. In this format, the sample reacts with dried virus specific reagents that have been immobilized on a solid matrix, such as nitrocellulose membrane. A positive result is indicated by a colour change which can be read by the user within 10-15 minutes. The biomarkers used for these devices differ from proteins, nucleic acids, metabolites, and microbes to microbe antigens found in various clinical samples which require only minimal or no preparation such as blood, saliva, urine and other bodily excretions. Validation of diagnostic performance of newly developed assays is often hampered by unavailability of well characterized clinical materials. Research activities related to the study of Ebola pseudotyped viral models: Platform of screening of Ebola Virus cell-entry inhibitors: Instituto de Investigacion Hospital Universitario 12 de Octubre, Madrid. Our screening platform allows rapid evaluation of antiviral potency to improve design of candidate compounds. The Ministry of Public Health will be implementing the program with technical support from related agencies. In addition, a device measuring body temperature has been installed at Suvarnabhumi airport. In addition, the Ministry has increased immigration screening measures for persons travelling from such countries. The Ministry of Public Health and associated agencies have prepared specific guidelines for preventing and controlling the spread of Ebola virus in all sectors under 3 possible scenarios as follows: 34 Overview of Ebola research – March 2015 No patient infected with the Ebola virus in Thailand, and no cases found of persons infected with the virus travelling into the country from abroad. Thus, increased aid measures have been proposed as follows: Monetary aid as estimated by the United Nations through funding from the Federal budget, and will collect addition funds from organisations such as the government, the Thai Red Cross and the public sector. Alternatively, 3 sets of medical personnel will be supported to the affected countries such as Guinea, Liberia and Sierra Leon for a period of 1 month each. A candidate Ebola vaccine is being tested as part of a series of safety trials of potential vaccines. This candidate vaccine is against the Zaire species of Ebola, and uses a single Ebola virus protein to generate an immune response. Pre-clinical research has indicated that it provides promising protection in non-human primates exposed to Ebola without significant adverse effects. EbolaCheck – Portable Device which tests bodily fluids for Ebola University of Westminster – Dr Sterghios Moschos this project looks at the development of a cost-effective, portable, battery-powered device which can provide reliable, rapid and safe diagnostic tests suitable for use in the field. EbolaCheck aims to test bodily fluids for Ebola in a single process, providing results within 40 minutes – over eight times quicker than some existing laboratory techniques. Predicting the geographic spread of Ebola virus disease in West Africa University of Oxford – Professor Simon Hay & Dr Nick Golding Using data on human mobility, population density and transport infrastructure in West African countries, this piece of research will make predictions about disease spread. This will enable resources to be deployed more effectively to contain the epidemic. The information will be mapped out and contain summaries of health centres most likely to see new cases. This will be continuously updated as data becomes available and shared through an online tool. Behaviour change to help infection prevention and control International Rescue Committee – Dr Lara Ho this research, being carried out in Sierra Leone, analyses the levels of knowledge and risks perceptions amongst health workers. The aim to help overcome barriers that staff may face in adhering to standard precautions. This will ensure that safety procedures and training for health workers is effective as possible to reduce the risk of infection while working on the front line. The study will look at what health care facilities will be needed to cope with different scenarios. Ebola Response Anthropology Platform London School of Hygiene & Tropical Medicine – Dr Melissa Parker An Ebola Response Anthropology Platform will look at developing locally-appropriate interventions. The project aims to provide rapid, practical advice on how to engage more effectively with affected populations. Rapid, point-of-care diagnostic test for the Ebola virus 36 Overview of Ebola research – March 2015 Pasteur Institute in Dakar, Senegal – Dr Amadou A Sall A rapid, point-of-care diagnostic test for the Ebola virus will be trialled in the coming weeks at the Ebola treatment centre in Conakry, Guinea. The trial will be deployed using a ‘mobile suitcase laboratory’ which is designed for low-resource settings. The portable laboratory includes a solar panel, a power pack and a results reader which is the size of a small laptop. Agency representatives indicated document markings are hindering data accessibility and sharing needed to support the Ebola response in West Africa (Department of Defense (DoD) and Department of State). An Ebola virus research working group has been created under the initiative to explore how investigators can address scientific questions associated with Ebola virus, including viral persistence studies on contaminated surfaces. Comparative sequence analysis of circulating West African strain(s) of Ebola virus, non-West African strains, and non-contemporary strains can provide additional evidence-based information on transmission and pathogenesis characteristics of Ebola virus to support medical countermeasure development. Department of Health and Human Services also specifically has the lead for monitoring the outbreak and developing new and improved Ebola countermeasures. We are supporting the development of five Ebola vaccine candidates in various stages of development. The results indicate that the vaccine candidate is safe and induces an immune response. Additional clinical trials of the vaccine are underway or imminent in Atlanta, Baltimore, the United Kingdom, Switzerland, and Mali, among other sites. The National Insitutes of Health collaborating with Liberian health authorities initiated a Phase 2 clincial studies Liberia in early February 2015 using a randomized controlled trial protocol to evaluate the safety and efficacy of two Ebola vaccine canddiates aginst a placebo control.

A wildlife pathologist who was enlisted to blood pressure chart emt order trandate cheap perform autopsies on several of the birds failed to arteria testicularis 100mg trandate sale identify the cause but ruled out common problems that could have killed so many of the crea tures prehypertension triples heart attack risk trandate 100mg fast delivery. Examiners at the New York State Department of Environmental Conservation could not identify any of the known toxins or parasites like bacteria or fungi in samples sent to prehypertension values purchase discount trandate line them for testing arrhythmia from caffeine buy trandate 100 mg with mastercard. Five days later two other patients with similar symptoms (indicators of illness that the patient describes) and signs (indicators that the doctor sees) (6) were admitted to blood pressure levels exercise order trandate 100 mg mastercard the hospital. One of the previous patients with the mysterious infection died, and an autopsy was performed (6,7). Meanwhile, the New York City Health Department sent epidemiologists to investigate the disease 236 Viruses, Plagues, and History outbreak in Queens. The epidemiologic eld investigator located numer ous mosquito breeding sites and mosquito larvae in and around the hospitalized patients’ backyards and surrounding neighborhoods, all pointing to a mosquito-borne disease as the possible culprit. At the same time, reports of bird deaths continued to increase, especially crows in New York City and as far as Buffalo. By the second week in September, when the head pathologist of the Bronx Zoo had recorded the deaths of over 400 birds, samples were sent to the U. Geological Survey at the National Wildlife Center, a federal government facility that assesses and diagnoses disease outbreak in birds and other animals. Meanwhile, the New York State Health Department reported evi dence of avivirus infection in the patients’ samples they had received. After being bitten by a mosquito bearing this virus, the victim develops an infection that reaches the brain, most likely by traveling in circulating blood, although spread via the peripheral nerves is also possible. Several members of the aviviral family are mosquito borne, have birds as their natural hosts, and cause encephalitis. Antibod ies to specic aviviruses are usually used to identify these pathogens in patients’ blood or tissues but often cross-react among various sub-species in the viral group. Therefore, positive diagnosis of a specic family mem ber rests primarily with distinguishing its genetic sequence and unique differences therein. One such laboratory, and the one actively involved in this investiga tion, is the Division of Vector-Borne Infectious Diseases at Fort Collins, Colorado. This unit deals with viral and bacterial diseases transmitted by mosquitoes and ticks and provides laboratory services for diagnoses of such vector-borne pathogens. Evaluating methods to prevent, treat, and control vector-borne outbreaks is also the work of this division. Louis encephalitis virus, a member of the avivirus group but never before reported in New York City. Louis encephalitis virus had caused most West Nile Virus: Deaths of Crows and Humans 237 of the mosquito-borne virus outbreaks of this nerve disease in the United States. The lower forty-eight states are home to this virus, which induces, on average, thirty to forty cases of encephalitis per year. Virtually equaling the entire country’s usual caseload, the number of patients with suspected encephalitis approached forty in the New York City area alone, and the eighth patient was admit ted to the Flushing Queens Hospital. These antigens are placed on a plate along with the serum portion from the patient’s blood. The New York Health Department initiated a mosquito control program for the city, disseminated public information about the disease, and established a hotline. Public hotlines now overowed with reports that large numbers of birds continued to die. Bird deaths increased further in the Bronx Zoo, throughout New York City and surrounding areas. The rst human outside of Queens who tested positive for this virus was reported in Brooklyn, and a third patient died in the Flushing Queens Hospital. As the number of patients with suspected avivirus infections grew through out New York City, the New York Times reported that public health ofcials were investigating additional cases over those already reported. Eight more patients died of encephalitis, and fteen more infected people in New York City and Westchester County were suspected of hosting the St. Louis encephalitis viruses had been identied by their reaction to antibodies, but those antibodies sometimes cross-reacted with several other mem bers of the avivirus group. Louis encephalitis viruses that were known generally were not toxic for birds; however, large numbers of birds were dying. Louis encephalitis virus infection did not usually include muscle weak ness, yet muscle weakness was prevalent among infected patients in the current outbreak. One of the attendees was Ian Lipkin, a professor of neurology and microbiology at the University of California Medi cal School in Irvine, who was head of a laboratory studying emerging diseases. Several years earlier, upon concluding his medical and neurology training, Ian applied to work with me in the Viral-Immunobiology Lab oratory at the Scripps Research Institute (at that time called Scripps Clinic and Research Foundation) in La Jolla, California. His research training was negligible; however, he showed a keen intellect and desire to learn what research was about and how to do it. His interest was to develop new assays for detecting infectious agents, primarily viruses that might be responsi ble for human diseases whose cause was unknown. The most serious, like multiple sclerosis, diabetes, amyotrophic lateral sclerosis (Lou Gehrig’s disease), and schizophrenia, were his special area of concern. His desire was to become a modern microbe hunter, a term coined for the earliest seekers of pathogens that kill and maim humanity. In my laboratory alone, the number dropped from 80 to 90 percent of my research staff in the 1970s to roughly 50 percent during his time with me to less than 5 percent for the last decade. This deciency in persons trained broadly in normal human biology and its diseases is more than a national concern; it is a disaster. Together, they provide a thirst for understanding the current issues of human diseases West Nile Virus: Deaths of Crows and Humans 239 in biomedicine with a balance between clinical and laboratory training. Only with this full set of skills is the ultimate goal of establishing causes, understanding mechanism(s) of disease, and devising therapies to cure and prevent human diseases likely to succeed. There are many causes why medical physicians are not entering the investigational research pool, and this crisis in biomedicine urgently requires correction. At this point, virologists at the National Wildlife Health Center had isolated viruses from birds but were not con vinced they were St. The Albany conference had also been designed to discuss new methods of detective virology for the rapid identication of disease-causing viruses. Lipkin, after leaving my laboratory to begin his own at the University of California, Irvine, had devised and set up rapid molecular biologic assays to screen for just such an infectious agent as that being sought in the New York City encephalitis outbreak. From contacts he made at the Albany meeting and following a lecture he gave about his rapid assays, participants recommended sending brain samples from infected patients to Lipkin for testing. State health ofcials also wished to evaluate Lipkin’s assay because they had failed to obtain positive results for St. Soon after the conference ended, the virology section of the New York State Department of Health sent samples to Lipkin’s laboratory. Six days later, Lipkin’s staff identied avivirus sequences in the brains of three patients. Genomic sequencing and aligning the materials obtained from the three human brains indi cated to Lipkin that the infectious agent was not St. Louis encephalitis virus but was, instead, most closely related to West Nile virus, a virus that had never before been seen in the United States, and to Kunjin virus. West Nile virus is toxic for several species of birds, and crows are highly susceptible (15–17). In our current world of rapid communication, many ndings like these are disseminated on the Internet or by Pro Med. When the reports linking West Nile virus with encephalitis reached Vincent Deubel of the Pasteur Institute in Paris, he replied that he had in his laboratory genomic sequences of West Nile virus that had never been published in the med ical literature. Moreover, he was willing to provide those sequences to assist in uncovering the cause of New York City’s outbreak of deadly viral infection. The time was by then the last week in September, just a little more than two weeks after the Albany Conference, when the source of blood from more than 50 percent of the infected birds surveyed were positive for West Nile virus. Department of Agriculture reported that a horse in Long Island was infected with what looked like West Nile virus. By the end of that same week in September, sixty-two cases of West Nile virus infection were veried in humans, and seven had died. The New York City Department of Health reported an additional 622 sus pected cases. One hundred and thirty of the dead birds were conrmed as infected with West Nile virus as were twenty-ve horses. By October, dead crows were found in Baltimore, other counties of New York State, Massachusetts, Connecticut, Rhode Island, and New Jersey. Over 25,000 mosquitoes were collected and put into 1,500 test pools; 15 of those pools tested positive for the virus. The mosquitoes involved were Culex pipiens, a type that inhabits polluted water and is active at night, and Aedes vexan, which occupy natural areas and are active during the day. The New York Daily News reported in the rst week of October 1999, “Ancient Disease is on the Move. However, very little activity by West Nile viruses was documented until a substantial outbreak in Israel during the 1950s. However, until the West Nile virus surfaced in New York City in 1999, the geographic distribution of this infection was limited to countries bordering the Mediterranean, the Middle East, Africa, and West Asia. But despite its stealthy entrance into New York City, the virus spread rapidly throughout the region involving the majority of American states (3,19, Table 13. This coverage represents the largest arbovirus epidemic of human encephalitis in history. The disease is trans mitted in enzootic cycles involving a variety of mosquitoes, but primarily the Culex species, and birds (1,2,20). The virus moves with infected migra tory birds as well as being maintained locally by resident birds (15). The infected birds fall into two major groups: those that carry the virus and are asymptomatic and those that develop an often fatal neu rologic disease. Crows, jays, magpies, and house nches, upon infection, develop high virus loads and rapidly infect the mosquitoes that prey on them (21–24). These birds, which are highly susceptible to the deadly West Nile Virus: Deaths of Crows and Humans 243 neurologic disease, are sentinels of virus activity whose deaths should be considered an alarm that West Nile virus has infested the community. House sparrows are also reservoirs for high titers of West Nile virus and play a role in the virus’s transmission in city areas. The current depletion of certain bird populations in North America, for example, the robin, is related to their infection by West Nile viruses (25). Humans are incidental/accidental hosts in the natural mosquito–bird cycle of this viral infection. In addition to humans, domestic and wild animals can intrude into the mosquito–bird cycle; some known examples are horses, cats, dogs, sheep, goats, rodents, bats, and even alligators (22). Most humans who become infected have received bites from mosquitoes carrying the West Nile virus. The viruses then replicate at the bite site and likely spread to specialized cells, dendritic cells, that act as proces sors of foreign antigens (in this case, the viruses). Subsequently, these viral antigens initiate both the rapid (innate) and adoptive (T cell [killer cells] and B cell [antibodies]) immune responses. Dendritic cells then carry processed virus material and probably infectious virus as well to the lym phoid system, from there to blood and then to other tissues. Since West Nile viruses travel in blood, they can also spread from human to human by transfusion, from mothers to their fetuses through the placenta and from organ donors to recipients of transplants (26,27). The clinical picture following West Nile virus infection is an asymp tomatic incubation period of two to fourteen days followed by mild symptoms, or none at all, in the majority or at least 80 percent of infected persons. That group experiences severe headaches, backaches, muscle pain, fever, and fatigue; half develop a rash. These observations were made in mice whose toll-like receptor 3, which is normally present, was genetically removed (28). The observation is that mice without toll-like receptor 3 were more resistant to lethal infection with West Nile virus 244 Viruses, Plagues, and History and had larger loads of virus in the periphery than the brain. In contrast, mice with the toll-like 3 receptors had smaller viral loads but inamma tion and tissue damage in their brains following West Nile virus infection. Thus, West Nile virus infection initiated peripherally after a mosquito bite led to a breakdown of the blood–brain barrier due to high cytokine and chemokine production followed by enhanced brain infection in mice possessing toll-like receptor 3. Since the 1999 outbreak in New York City, West Nile virus has been responsible for major epidemics of neurologic disease throughout the United States in 2002, 2003, and thereafter. Over 2 percent of residents in the Queens borough of New York City, the epicenter of the out break, were infected. As of March 2008, throughout this country, over 28,000 cases of West Nile virus infection have been recorded; of these, over 11,000 individuals suffered neurologic involvement and over 1,000 died (3). Just as canaries have been used in mines to detect gas leakage, crows can warn that West Nile virus is present. The unique susceptibility of crows to North American strain(s) of West Nile virus (14,15) and the birds’ close association with human habitation in almost all areas except the Southwestern desert make them an excellent indicator for the active presence of West Nile virus. This mutation of a single amino acid allows selection for a strain of West Nile virus that replicates with such robust vigor in susceptible birds that the amount of virus in their blood is nearly 10,000 to 100,000-fold greater than that of the nonmutated West Nile virus. The heightened level of virus in the blood not only for crows but for other susceptible birds as well provides the best opportunity possible for a mosquito to become infected West Nile Virus: Deaths of Crows and Humans 245 when biting that bird. The emergence of West Nile virus in North America correlates directly with the large-scale decline of the North American bird pop ulation (30). Populations of birds that are resistant to West Nile virus like the mourning dove, downy woodpecker, Northern mockingbird, wood thrush, Baltimore oriole, Eastern towhee, and the white-breasted nuthatch remain undiminished. Flocks of birds with moderate or intermediate susceptibility to West Nile virus like the common grackle, Northern cardinal, and the song spar row have been reduced somewhat in size but not as greatly as the most susceptible bird populations. Thus, this recent redistribution in the bird population is not caused primarily by changes in local environment, bird habitat, land usage, or climate, since these variables were taken into account when the numbers of birds in each group were calculated. For no other reason than the epidemic of West Nile virus infection, the bird communities and populations most commonly associated with humans in towns and suburbs where the mosquito–bird/mosquito–human cycle ourishes have undergone drastic changes.

Methods of control—The control of human brucellosis rests on the elimination of the disease among domestic animals pulse pressure for dengue generic 100 mg trandate overnight delivery. Preventive measures: 1) Educate the public (especially tourists) regarding the risks associated with drinking untreated milk or eating products made from unpasteurized or otherwise untreated milk arteria subscapularis discount trandate 100 mg on-line. In high-prevalence areas blood pressure medication recreational buy cheap trandate 100mg on-line, immunize young goats and sheep with live attenuated Rev-1 strain of B arrhythmia consultants greenville sc discount trandate generic. This must be taken into account when treating human cases of animal vaccine infections pulse pressure 41 generic trandate 100 mg visa, which are otherwise to arrhythmia guideline cheap 100mg trandate overnight delivery be treated like other human cases of brucellosis. Tetracycline should preferably be avoided in children under 7 to avoid tooth staining. Relapses occur in about 5% of patients treated with doxycycline and rifampicin and are due to sequestered rather than resistant organisms; patients should be treated again with the original regimen. Epidemic measures: Search for common vehicle of infection, usually raw milk or milk products, especially cheese, from an infected herd. Recall incriminated products; stop production and distribution unless pasteurization is instituted. International measures: Control of domestic animals and animal products in international trade and transport. Measures in the case of deliberate use: Their potential to infect humans and animals through aerosol exposition is such that Brucella species may be used as potent biological weapons. Identication—Classically, Buruli ulcer presents as a chronic essentially painless skin ulcer with undermined edges and a necrotic whitish or yellowish base (“cotton wool” appearance). Most lesions are located on the extremities and occur among children living near wetlands in rural tropical environments. Buruli ulcer often starts as a painless nodule or a papule, which eventually ulcerates; other presentations, such as plaques and indurated oedematous lesions, represent a rapidly dissemi nated form that does not pass through a nodular stage. Bones and joints may be affected by direct spread from an overlying cutaneous lesion of Buruli ulcer or through the blood stream; osteomyelitis due to Mycobac terium ulcerans is being reported with increasing frequency. Long neglected or poorly managed patients usually present with scars— sometimes hypertrophic or keloid, with partially healed areas or disabling contractures, especially for lesions that cross joints. Marjolin ulcers (squamous cell carcinoma) may develop in unstable or chronic non pigmented scars. In experienced hands and in endemic areas, diagnosis can usually be made on clinical grounds. Histopathological features of active disease include the contiguous coagulation necrosis of subcutaneous fat and demonstration of acid-fast bacilli. Mycolactone production varies with the different groups and is maximal in the African strain. Numbers of reported cases have been increasing over the last 25 years, most strikingly in western Africa, where M. Reservoir—Some evidence points to the environment of the fauna and ora and other ecological factors in the wetlands. Water-dwelling insects, snails and sh are naturally infected and may serve as natural hosts for M. In Australia, it has been described not only in humans but also in native animals including the koala (Phascolarctos cinereus), the brushtail and ringtail possum (family Phalangeridae) and the long-footed potoroo (Potorous longipes). There has been a case reported in a domesticated alpaca (Lama pacos); all of these except for those in the potoroo occurred in the focal areas where human cases occurred. Mode of transmission—In most studies a signicant number of patients had antecedent trauma at the site of the lesion. Recent evidence suggests that aquatic insects (Naucoridae) may be natural reser voirs and their bite may transmit the disease to humans. Snails belonging to the families of Ampullariidae and Planorbidae could be contaminated after feeding on aquatic plants covered by a biolm of M. Environmental changes that promote ooding, such as deforestation, dam construction and irrigation systems, are often associated with out breaks of Buruli ulcer. Population increases in rural wetlands place increasing populations at risk during manual farming activities. Lack of protected water supplies contributes to dependence on pond water for domestic use. Incubation period—Incubation period is about 2 3 months; anecdotal observations suggest that M. As for tuberculosis, it is believed that only a small proportion of infected people develop the disease. Period of communicability—Interhuman transmission of Buruli ulcer in the eld is exceptional; rare cases have developed in caretakers of Buruli ulcer patients. Most, however, are believed to abort the disease in a preclinical stage and others show only small lesions that are rapidly self-healing. Residence or travel to the permanent wetlands of endemic areas, regular contact with the contam inated aquatic environment, and local trauma to the skin are known risk factors. Factors that probably determine the type of disease are dose of agent, depth of inoculation of the agent, host immunological response. Control of patients, contacts and immediate environment: 1) Report to local health authority: Although neither a notifiable nor a contagious disease, it is recommended that cases be reported to local health authorities because of its emerg ing nature. Specic antibiotics—rifampicin and an aminoglycoside (streptomycin or amikacin)—given for at least 4 weeks and not more than 12 weeks. Antibiotics should be started 1 or 2 days before the initial surgery to minimize M. Clinical improvements will dictate continua tion of antibiotherapy or further surgical intervention. Epidemics are very uncommon and call for education, cleanliness, early reporting, and the provision of wound care materials. Disaster implications: During wars and other conicts, diag nosis and treatment of patients is neglected because the health care infrastructure needed to treat patients is disrupted or destroyed. International measures: Endemic countries should coordinate efforts across borders. Health workers in non-endemic areas must be aware of the disease and its management because of international travel. Identication—An acute zoonotic bacterial enteric disease of variable severity characterized by diarrhea (frequently with bloody stools), abdominal pain, malaise, fever, nausea and/or vomiting. Less common forms include a typhoid-like syndrome, febrile convulsions, meningeal syn drome; rarely, post-infectious complications include reactive arthritis, febrile convulsions or Guillain-Barre syndrome. Diagnosis is based on isolation of the organisms from stools using selective media, reduced oxygen tension and incubation at 43°C (109. Visualization of motile and curved, spiral or S-shaped rods similar to those of Vibrio cholerae by stool phase contrast or darkeld microscopy can provide rapid presumptive evidence for Campylobacter enteritis. At least 20 biotypes and serotypes occur; their identication may be helpful for epidemiological purposes. Occurrence—These organisms are an important cause of diar rheal illness in all age groups, causing 5%–14% of diarrhea worldwide. In industrialized countries; children under 5 and young adults have the highest inci dence of illness. Persons who are immunocompromised show an increased risk for infection and recurrences, more severe symptoms and a greater likelihood of being chronic carriers. In developing countries, illness is conned largely to children under 2, especially infants. Common-source outbreaks have occurred, most often associ ated with foods, especially undercooked poultry, unpasteurized milk and nonchlorinated water. The largest numbers of sporadic cases in temperate areas occur in the warmer months. Puppies, kittens, other pets, swine, sheep, rodents and birds may also be sources of human infection. Mode of transmission—Ingestion of the organisms in under cooked meat, contaminated food and water, or raw milk; from contact with infected pets (especially puppies and kittens), farm animals or infected infants. Contamination of milk usually occurs from intestinal carrier cattle; people and food can be contaminated from poultry, especially from common cutting boards. Incubation period—Usually 2 to 5 days, with a range of 1–10 days, depending on dose ingested. Period of communicability—Throughout the course of infection; usually several days to several weeks. The temporary carrier state is probably of little epidemiological importance, except for infants and others who are incontinent of stool. Chronic infection of poultry and other animals constitutes the primary source of infection. Susceptibility—Immune mechanisms are not well understood, but lasting immunity to serologically related strains follows infection. In developing countries, most people develop immunity in the rst 2 years of life. Preventive measures: 1) Control and prevention measures at all stages of the food chain, from agricultural production on the farm to process ing, manufacturing and preparation of foods in both commer cial establishments and the domestic environment. Use irradiated foods or thoroughly cook all animal foodstuffs, particularly poultry. Avoid common cutting boards and re contamination from uncooked foods within the kitchen after cooking is completed. Comprehensive control programs and hygienic measures (change of boots and clothes; thorough cleaning and disinfection) to prevent spread of organisms in poultry and animal farms. Good slaughtering and handling practices will reduce contamination of carcases and meat products. Puppies and kittens with diarrhea are possible sources of infection; erythromycin may be used to treat their infections, reducing risk of transmission to children. Control of patient, contacts and the immediate environment: 1) Report to local health authority: Obligatory case report in several countries, Class 2 (see Reporting). Ex clude symptomatic individuals from food handling or care of people in hospitals, custodial institutions and day care cen tres; exclude asymptomatic convalescent stool-positive indi viduals only for those with questionable handwashing habits. In communities with an adequate sewage dis posal system, feces can be discharged directly into sewers without preliminary disinfection. Identication—A mycosis usually conned to the supercial layers of skin or mucous membranes, presenting clinically as oral thrush, intertrigo, vulvovaginitis, paronychia or onychomycosis. The single most valuable laboratory test is microscopic demonstration of pseudohyphae and/or yeast cells in infected tissue or body uids. Culture conrmation is important, but isolation from sputum, bronchial washings, stool, urine, mucosal surfaces, skin or wounds is not proof of a causal relationship to the disease. Candida (Torulopsis) glabrata is distinguished from other causes of candidiasis by lack of pseudohyphae formation in tissue. Mode of transmission—Contact with secretions or excretions of mouth, skin, vagina and feces, from patients or carriers; by passage from mother to neonate during childbirth; and by endogenous spread. Susceptibility—The frequent isolation of Candida species from sputum, throat, feces and urine in the absence of clinical evidence of infection suggests a low level of pathogenicity or widespread immu nity. Oral thrush is a common, usually benign condition during the rst few weeks of life. Local factors contributing to supercial candidiasis include interdigital intertrigo and paronychia on hands with excessive water exposure. Uri nary tract candidiasis usually arises as a complication of prolonged catheterization of the bladder or renal pelvis. Most adults and older children have a delayed dermal hypersensitivity to the fungus and possess humoral antibodies. Preventive measures: Early detection and local treatment of any infection in the mouth, oesophagus or urinary bladder of those with predisposing systemic factors (see Susceptibility) to prevent systemic spread. Fluconazole chemoprophylaxis de creases the incidence of deep candidiasis during the rst 2 months following allogenic bone marrow transplantation. Anti fungal agents that are absorbed fully (uconazole, ketocon azole, itraconazole) or partially (miconazole, clotrimazole) from the gastrointestinal tract have been found to be effective in preventing oral candidiasis in cancer patients receiving chemotherapy. Topical nystatin or an azole (miconazole, clotrimazole, ketoconazole, ucon azole) is useful in many forms of supercial candidiasis. Oral clotrimazole troches or nystatin suspension are effec tive for treatment of oral thrush. Itraconazole suspension or uconazole is effective in oral and oesophageal candi diasis. Epidemic measures: Outbreaks are most frequently due to contaminated intravenous solutions and thrush in nurseries for newborns. Identication—First described in Luzon, Philippines, in the early 1960s, the disease is clinically an enteropathy with massive protein loss and a malabsorption syndrome leading to progressive weight loss and emaciation. Fatal cases are characterized by the presence of great numbers of parasites in the small intestine together with ascites and pleural transudate. Diagnosis is based on clinical ndings plus the identication of eggs or larval or adult parasites in the stool. Occurrence—Intestinal capillariasis is endemic in the Philippines and in Thailand; cases have been reported from Egypt, Japan, the Republic of Korea and Taiwan (China). Isolated cases have also been reported from Colombia, India, Indonesia, and the Islamic Republic of Iran. Mode of transmission—A history of ingestion of raw or inade quately cooked small sh eaten whole is usually obtained from patients. Experimentally, infective larvae develop in the intestines of freshwater sh that ingest eggs; monkeys, Mongolian gerbils and some birds fed these sh become infected, the parasite maturing within their intestines. Susceptibility—Susceptibility appears to be general in those geo graphic areas in which the parasite is prevalent. Preventive measures: 1) Avoid eating uncooked sh or other aquatic animal life in known endemic areas.
