  1. Adolpho Lutz and the origins of medical entomology in Brazil.

    2005-12-01

    Adolpho Lutz (1855-1940) formed a bridge between the Bahian Tropicalist School and post-Mansonian medicine. Before taking over as head of the São Paulo Bacteriological Institute (1893), Lutz traveled through a variety of regions and delved into various disciplines. In the 1880s, he was already arguing that leprosy was transmitted by mosquitoes. Carbuncles, cholera, and typhoid fever were then the accepted models for investigating the etiology of infectious diseases. Following the discovery of how malaria was transmitted, attention turned to hematophagous diptera. Physicians, bacteriologists, zoologists, and veterinarians reshaped the network of actors involved in the 'hunt' for the agents and transmitters of diseases, as they began relying on analogies with malaria and yellow fever. Edwin Ray Lankester, director of the British Museum (Natural History), launched then a worldwide investigation into species that might be linked to human disease. The species described by Lutz and his proposed classification system were vital to Frederick Theobald's fundamental work in medical entomology, published in the early twentieth century. In 1908, Lutz brought with him to the Oswaldo Cruz Institute a remarkable quantity of research and experiments in all branches of the newly created "tropical medicine," devoted especially to entomology.

    Parasite findings in sambaquis (shell mounds) are scarce. Although the 121 shell mound samples were previously analysed in our laboratory, we only recently obtained the first positive results. In the sambaqui of Guapi, Rio de Janeiro, Brazil, paleoparasitological analysis was performed on sediment samples collected from various archaeological layers, including the superficial layer as a control. Eggs of Acanthocephala, Ascaridoidea and Heterakoidea were found in the archaeological layers. We applied various techniques and concluded that Lutz's spontaneous sedimentation technique is effective for concentrating parasite eggs in sambaqui soil for microscopic analysis. PMID:23579793

    Antecedentes y Objetivo: En México, el 64% de los pacientes hospitalizados sufren de desnutrición hospitalaria y hasta un 100% en adultos mayores, se han estudiado las causas, entre ellas se destacan: la sub-alimentación, el tiempo de hospitalización, el catabolismo presente en diversas patologías, falta de interés o tiempo del personal que labora en los hospitales entre otras. El objetivo del presente trabajo fue obtener la prevalencia de sub-alimentación en los pacientes hospitalizados con soporte enteral, en el Centro Médico “Lic. Adolfo López Mateos” (CMLALM) durante el periodo Agosto – Octubre 2014. Metodología: Se diseñó un estudio observacional, transversal, descriptivo; con una población de 52 pacientes con soporte enteral en el que se analizó la prevalencia de pacientes con sub-alimentación a partir de la ministración de la dieta enteral y la prescripción nutricional calórica establecida, durante el periodo de Agosto – Octubre 2014. Resultados: Se realizaron medidas de tendencia central para obtener el porcentaje de pacientes con sub-alimentación calórica. La prevalencia de pacientes con sub-alimentación fue del 71%, con mayor predominio el sexo masculino (70%) y en un rango de edad entre 51 años y 61 años (43%). El servicio médico de hospitalización donde se encontró la mayor prevalencia de pacientes con sub-alimentación fue medicina interna afectando a 14 pacientes (38%), seguido de neurocirugía con 7 pacientes (19%) y unidad de cuidados intensivos (UCI) con 7 pacientes (19%); siendo el turno nocturno donde se presentó en mayor predominio la sub-alimentación. Conclusiones: La sub-alimentación afectó a 37 pacientes con soporte enteral los cuales representan el 71% de la población estudiada, esta cifra coincide con otros estudios similares. La causa principal de la sub-alimentación fue el incumplimiento en la ministración de la dieta enteral.

    Purpose: To optimize clinical efficiency and shorten patient wait time by minimizing the time and effort required to perform the Winston-Lutz test before stereotactic radiosurgery (SRS) through automation of the delivery, analysis, and documentation of results. Methods: The radiation fields of the Winston-Lutz (WL) test were created in a “machine-QA patient” saved in ARIA for use before SRS cases. Images of the BRW target ball placed at mechanical isocenter are captured with the portal imager for each of four, 2cm×2cm, MLC-shaped beams. When the WL plan is delivered and closed, this event is detected by in-house software called EventNet which automates subsequent processes with the aid of the ARIA web services. Images are automatically retrieved from the ARIA database and analyzed to determine the offset of the target ball from radiation isocenter. The results are posted to a website and a composite summary image of the results is pushed back into ImageBrowser for review and authenticated documentation. Results: The total time to perform the test was reduced from 20-25 minutes to less than 4 minutes. The results were found to be more accurate and consistent than the previous method which used radiochromic film. The images were also analyzed with DoseLab for comparison. The difference between the film and automated WL results in the X and Y direction and the radius were (−0.17 +/− 0.28) mm, (0.21 +/− 0.20) mm and (−0.14 +/− 0.27) mm, respectively. The difference between the DoseLab and automated WL results were (−0.05 +/− 0.06) mm, (−0.01 +/− 0.02) mm and (0.01 +/− 0.07) mm, respectively. Conclusions: This process reduced patient wait times by 15–20 minutes making the treatment machine available to treat another patient. Accuracy and consistency of results were improved over the previous method and were comparable to other commercial solutions. Access to the ARIA web services is made possible through an Eclipse co-development agreement

  8. SU-E-J-117: Verification Method for the Detection Accuracy of Automatic Winston Lutz Test

    2014-06-01

    Purpose: Winston Lutz test (WLT) has been a standard QA procedure performed prior to SRS treatment, to verify the mechanical iso-center setup accuracy upon different Gantry/Couch movements. Several detection algorithms exist,for analyzing the ball-radiation field alignment automatically. However, the accuracy of these algorithms have not been fully addressed. Here, we reveal the possible errors arise from each step in WLT, and verify the software detection accuracy with the Rectilinear Phantom Pointer (RLPP), a tool commonly used for aligning treatment plan coordinate with mechanical iso-center. Methods: WLT was performed with the radio-opaque ball mounted on a MIS and irradiated onto EDR2 films. The films were scanned and processed with an in-house Matlab program for automatic iso-center detection. Tests were also performed to identify the errors arise from setup, film development and scanning process. The radioopaque ball was then mounted onto the RLPP, and offset laterally and longitudinally in 7 known positions ( 0, ±0.2, ±0.5, ±0.8 mm) manually for irradiations. The gantry and couch was set to zero degree for all irradiation. The same scanned images were processed repeatedly to check the repeatability of the software. Results: Miminal discrepancies (mean=0.05mm) were detected with 2 films overlapped and irradiated but developed separately. This reveals the error arise from film processor and scanner alone. Maximum setup errors were found to be around 0.2mm, by analyzing data collected from 10 irradiations over 2 months. For the known shift introduced using the RLPP, the results agree with the manual offset, and fit linearly (R{sup 2}>0.99) when plotted relative to the first ball with zero shift. Conclusion: We systematically reveal the possible errors arise from each step in WLT, and introduce a simple method to verify the detection accuracy of our in-house software using a clinically available tool.

    Eighteen strains of L. interrogans isolated from human cases were serotyped by the agglutinin-absorption test at Instituto Adolfo Lutz in São Paulo, Brazil. Fourteen were identified as serovar copenhageni (icterohaemorrhagiae serogroup), 2 as canicola (canicola serogroup), 1 as castellonis (Ballum serogroup) and 1 as pomona serogroup (serovar not yet defined). The frequency of serovar copenhageni in 100% of the isolates in icterohaemorrhagiae serogroup is emphasized and more studies to verify the real serovars prevalence as subsidy to the epidemiology of this infection are suggested by the authors.

    In Winston-Lutz (WL) tests, the isocenter of a linear accelerator (linac) is determined as the intersection of radiation central axes (CAX) from multiple gantry, collimator, and couch angles. It is well known that the CAX can wobble due to mechanical imperfections of the linac. Previous studies suggested that the wobble varies with gantry and collimator angles. Therefore, the isocenter determined in the WL tests has a profound dependence on the gantry and collimator angles at which CAX are sampled. In this study, we evaluated the systematic and random errors in the iso-centers determined with different CAX sampling schemes. Digital WL tests were performed on six linacs. For each WL test, 63 CAX were sampled at nine gantry angles and seven collimator angles. Subsets of these data were used to simulate the effects of various CAX sampling schemes. An isocenter was calculated from each subset of CAX and compared against the reference isocenter, which was calculated from 48 opposing CAX. The differences between the calculated isocenters and the reference isocenters ranged from 0 to 0.8 mm. The differences diminished to less than 0.2 mm when 24 or more CAX were sampled. Isocenters determined with collimator 0° were vertically lower than those determined with collimator 90° and 270°. Isocenter localization errors in the longitudinal direction (along the axis of gantry rotation) showed a strong dependence on the collimator angle selected. The errors in all directions were significantly reduced when opposing collimator angles and opposing gantry angles were employed. The isocenter localization errors were less than 0.2 mm with the common CAX sampling scheme, which used four cardinal gantry angles and two opposing collimator angles. Reproducibility stud-ies on one linac showed that the mean and maximum variations of CAX during the WL tests were 0.053 mm and 0.30 mm, respectively. The maximal variation in the resulting isocenters was 0.068 mm if 48 CAX were used, or 0

    Stereotactic radiosurgery (SRS) and radiotherapy (SRT) are intricate techniques that deliver a highly precise radiation dose to a localized target, usually a tumor. At our hospital, we perform SRS and SRT on brain tumors using a linear accelerator (linac) mounted with an external micro multi-leaf system. The Task Group TG-142 Report by the American Association of Physicists in Medicine recommends the coincidence of the radiation and mechanical isocenter to be within ±1 mm. The Winston-Lutz test is commonly used to verify the linac isocenter position: it has the advantages of being a simple method that uses a film or electronic portal imaging device (EPID). However, the film method requires a higher radiation dose, which makes it more time-consuming than the EPID method, and the results are highly dependent on the skills of the observer. The EPID method has certain advantages over the film method, but it has low resolution and can only be used for a few combinations of gantry and couch angles. This prompted us to develop an in-house-designed radiation receptor system based on digital radiography, using a photostimulable storage phosphor and automated analysis algorithm for Winston-Lutz test images using a template-matching technique based on cross-correlation coefficients. Our proposed method shows a maximum average absolute error of 0.222 mm (less than 2 pixels) for 0.5 mm and 1.0 mm displacement from the isocenter toward the inline and crossline directions. Our proposed method is thus potentially useful for verifying the Linac isocenter position with a small error and good reproducibility, as demonstrated by improved accuracy of evaluation.

    In Peru, the industry's development has made economic improvements but at the same time, it has had a major impact on the health of the workers; for that reason, it was necessary to generate control mechanisms. So, in 1940 it was created the Departmento de Higiene Industrial, which in 1956 was changed to Instituto de Salud Ocupacional, but it was deactivated in 1994. However, in 2001 it reappeared into the Ministerio de Salud organizational structure with the name of Instituto de Salud Ocupacional "Alberto Hurtado Abadía". Actually, it is the Centro Nacional de Salud Ocupacional y Protección del Ambiente para la Salud (CENSOPAS), organ of the Instituto Nacional de Salud which continues working in synergy with other institutions and sectors, making research to protect the health of exposed persons (workers and community) to contamination and risks associated with economic activities.

    We develop in this paper the activities of "Instituto de Terapeutica Operatoria" during the fifty-seven years of its existence (1880-1939). It was founded by Federico Rubio (1827-1902). We consider three periods of existence for the institute: First: From its foundation (in "Hospital de la Princesa", 1880-1896) and during the next sixteen years. This period saw the beginning of graduate formation for doctors. Second: Building and activities in Moncloa (1896-1902), during six years, while his creator was still alive. He edited the "Revista Iberoamericana de Ciencias Médicas") and started the first Spanish school of infirmary (Santa Isabel de Hungría). Thirth: (1902-1939) About thirty-seven years, until the institute dissapears because of the Spanish Civil War. The Instituto de Terapeutica Operatoria was also know as Instituto Rubio or "Clínica de la Moncloa". Many medical specialities were first created (in Spain) in this place: Surgery, Gynaecology, Urology, Otorhinolaryngology, etc. Rubio, as a surgeon, was a pioneer in many interventions: ovary (1860), uterus (1861), upper maxilar ressection (1864), larynx (1870). His personality and legate was the one of a liberal politician, pedagogyst, writer o academy member (RANM). Many doctors got attached to his teachings: E. Gutiérrez, Ariza, Buissen, Martínez Angel, Pulido, Sarabia, Suender, González Bravo, López Durán, Landete, Cervera, Albitos, Botín, etc. Just in place where the "Instituto" was sited, now there is the "Clinica de la Concepción", built in 1955.

    The phlebotomine sand flies Nyssomyia intermedia (Lutz & Neiva, 1912) and Nyssomyia neivai (Pinto, 1926) are very close and may be involved in the transmission of Leishmania spp. Ross, 1903 in Brazil. The biology of the first laboratory-reared generations of these species, descended from insects captured in Além Paraíba (N. intermedia) and Corinto (N. neivai) in the Brazilian state of Minas Gerais, is described here. The captured females were fed on hamsters and maintained individually in rearing pots. Laboratory temperature and relative humidity were maintained at 25-26 masculineC and 80% respectively. The productivity of the first generation of N. intermedia was greater than that of N. neivai, and its development time clearly shorter, particularly for the second and third larval instars.

    Entomological surveys in the state of Maranhão have recorded morphologically distinct populations of Lutzomyia longipalpis (Lutz & Neiva). Some populations have one pair of spots (1S) on the fourth tergite, while others have two pairs (2S) on the third and fourth tergites of males. In the present study we investigated the degree of genetic polymorphism among four populations in the municipalities of Caxias, Codó and Raposa, in the state of Maranhão, Brazil, by using RAPD (Random Amplified Polymorphic DNA) markers. A total of 35 loci were identified, of which 30 were polymorphic. The highest polymorphism was observed with primer OPA 4, which produced 11 different profiles. Genetic diversity was assessed using grouping methods that produced a dendrogram in which the genotypes could be clearly separated into two main clades according to the number of spots on the male abdominal tergites. One cluster contained the populations from Caxias and Codó, and the other was formed by the populations from Raposa and Codó. The results of our RAPD analysis showed a clear separation between the populations with one and two pairs of spots. The epidemiologic significance of this genetic differentiation should be investigated in future studies.

    The journal Memórias do Instituto Oswaldo Cruz, founded and maintained over the course of many years for the exclusive publication of research results from one single institution, has undergone changes over the last decade which have resulted in an open journal. Conditions leading to the journal's founding and the excellent role it has played in the dissemination of knowledge produced by the Instituto Oswaldo Cruz are examined. The fact that it has differed from journals published by scientific societies does not diminish its importance. The present option to give this journal an international slant, with possibilities for competing on the foreign market, and which would be facilitated by the preference given to papers written in English, raises some questions about the role of Brazilian specialized journals within the framework of our scientific development.

    In Spain, there is an Instituto de Astrofísica de Canarias in Tenerife, an Instituto de Astrofísica de Andalucía in Granada and an Institut d'Estudis Espacials de Catalunya in Barcelona. However, there is not an Instituto de Astrofísica de Madrid (IAM). Actually, Madrilenian astronomers are spread over a number of institutions of quite different origin, size and funding source. The IAM, if it existed, would be a catalyzer of ideas and collaborations, an international meeting point, an engine for high-technology industry in the region, and an excellence centre. Furthermore, the IAM would maximise the efficiency in the use of resources, offer a place for finding synergies between research groups and, especially, have a critical mass for embarking in very large projects in the ground and space. I will expose how, in a smooth and democratic way, an IAM might be built step by step. The process may take decades and, thus, young Madrilenian astronomers shall play a rôle on it.

Although up to then I had not worked in fluid dynamics, he accepted me under the condition to build up a lab from scratch to carry out experiments on convection. I agreed enthusiastically, yet not every Ph.D. student has the opportunity to carry out his research in a new lab—and on top of this, a lab one has a lot of freedom to design.

    The purpose of these lines is to remember and refer some of the historical landmarks in the evolution of the medical services of the Instituto Mexicano del Seguro Social (IMSS, according to its initials in Spanish) since it was founded, in 1943. We also want to bring to the reader's attention that the dimensions and impacts on health that IMSS has achieved, throughout its history, have strengthened the citizenship, as well as social sustainability. Also, those impacts have determined the creation and the reinforcement of human capital in México. Throughout this concise balance, all the controversy surrounding the foundation of the Institute is being recalled (the protest in the Mexico City Zócalo, or the attack to an hospital in San Ángel -a neighborhood located in the Southwest of Mexico City-), as well as the way the IMSS incorporated several words into the vocabulary of Mexicans. We also remember the previous antecedent of the Revista Médica del Instituto Mexicano del Seguro Social, as well as the Revista de Enfermería, and the emblematic Archives of Medical Research. The IMSS has 70 years of achievements, seven decades covered.

    During the past 10 years, the Instituto Nacional de Salud Pública (National Institute of Public Health) in Mexico has meticulously revised its educational model. This analysis resulted in the transformation of its educational model by tracing a new path in the pedagogical structure and faculty development to meet current challenges and students' needs.

    Mortality is an indicator that allow us to evaluate HIV infection control programs. From the middle of the last decade, mortality presents a tendency to decrease in the population covered by the Instituto Mexicano del Seguro Social). In relation to gender and age group the most affected are men between 25 to 44 years of age with mortality rates ranging from 30 to 12 by 100,000 men (1995 to 2009 respectively). In 2009, at least half of the Delegaciones (administrative units by State) present larger mortality rates than the institutional average, particularly Campeche with 14.9 by 100,000 men. It is clear that introduction of control measures against the disease from infected people represents a modification in the course of the illness in the population covered by IMSS.

    Diabetes is major contributor to the mortality in the Mexican population and particularly in the population insured by social security institutions like The Instituto Mexicano del Seguro Social (IMSS). Mortality rates have duplicated from 1990 to 2005 period and in some regions the increment has been even higher and faster. Men not insured by IMSS present the lowest mortality rates. Mortality by chronic diseases is no longer a problem of affluent regions since Chiapas, Oaxaca and Guerrero, the poorest states in the country, have higher rates of increment than the northern and more developed regions. The different interventions employed by the health institutions should impact mortality rates in both the magnitude and velocity of increment especially in those regions where growth of mortality have been higher.

    Medical research in the Instituto Mexicano del Seguro Social has been considered one of the most important in this country for quality and quantity. Thanks to the work and leadership of Benito Coquet, who initiated the building of the National Medical Center in 1961, and the work of two pillars of research, Luis Castelazo and Bernardo Sepúlveda, the Institute successfully improved scientific research. In the years that followed, the Institute fostered the professionalization of research, the creation of research units in different areas of science, the incorporation of consolidated groups of researchers, the relationship with other institutions, the incorporation to the Sistema Nacional de Investigadores, the editing of a journal to expose outside the work done within the Institute, and the formation of a trust to raise funds for financing. Thanks to all that, institutional research strengthened in all lines, and it was placed first, at certain times, at the national level.

    The journals of medicine arose as a communication tool more than 200 years ago. At the beginning, their nature was local; later, their aim was to spread medical information along the nation; and, finally, they sought to reach the world distribution. The Revista Médica del Instituto Mexicano del Seguro Social was published for the first time 52 years ago, and it has walked its way from local to international distribution. This journal has 23 000 subscribers, it is included in Medline and it reached a 0.112 SCImago Journal Rank in 2012. Its website receives around 200 000 visits monthly and 45 % are foreign visits. In the future, the peer review system is going to be strengthened, and the journal is going to offer audio, video, and applications to reinforce interactive participation between authors, readers in order to reach modernity and draw young new attention.

    The Real Instituto y Observatorio de la Armada (ROA) meridian circle was moved to the Estación de Altura Carlos Ulrrico Cesco in the República Argentina in 1996. Until November 1999 the observations were carried out with a moving slit micrometer. In spring 2001 the result of these observations has been published, forming the first Hispano-Argentinian Meridian Catalogue (HAMC). In December 1999 was installed a SpectraSource CCD camera of 1552×1024 pixels of 9 μ. The CCD camera observes in drift scan mode. A survey of the southern hemisphere is being observed from +3° to -60° of declination. In this contribution is presented a description of the telescope and the automatic control system, the results of observations carried out with the slit micrometer, and the observational and preliminary reduction techniques with the CCD camera, the present state of the southern hemisphere survey and the future possibilities.

    Ambient dose equivalent values were determined in several sites at the Instituto Nacional de Cancerologia, Departmento de Medicina Nuclear, using TLD-100 and TLD-900 thermoluminescent dosemeters. Additionally, ambient dose equivalent was measured at a corridor outside the hospitalization room for patients treated with {sup 137}Cs brachytherapy. Dosemeter calibration was performed at the Instituto Nacional de Investigaciones Nucleares, Laboratorio de Metrologia, to known {sup 137}Cs gamma radiation air kerma. Radionuclides considered for this study are {sup 131}I, {sup 18}F, {sup 67}Ga, {sup 99m}Tc, {sup 111}In, {sup 201}Tl and {sup 137}Cs, with main gamma energies between 93 and 662 keV. Dosemeters were placed during a five month period in the nuclear medicine rooms (containing gamma-cameras), injection corridor, patient waiting areas, PET/CT study room, hot lab, waste storage room and corridors next to the hospitalization rooms for patients treated with {sup 131}I and {sup 137}Cs. High dose values were found at the waste storage room, outside corridor of {sup 137}Cs brachytherapy patients and PET/CT area. Ambient dose equivalent rate obtained for the {sup 137}Cs brachytherapy corridor is equal to (18.51{+-}0.02)x10{sup -3} mSv/h. Sites with minimum doses are the gamma camera rooms, having ambient dose equivalent rates equal to (0.05{+-}0.03)x10{sup -3} mSv/h. Recommendations have been given to the Department authorities so that further actions are taken to reduce doses at high dose sites in order to comply with the ALARA principle (as low as reasonably achievable).

    In 1988, the Instituto Geofisico (IG) began a permanent surveillance of Ecuadorian volcanoes, and due to activity on Guagua Pichincha, SP seismic stations and EDM control lines were then installed. Later, with the UNDRO and OAS projects, telemetered seismic monitoring was expanded to Tungurahua, Cotopaxi, Cuicocha, Chimborazo, Antisana, Cayambe, Cerro Negro, and Quilotoa volcanoes. In 1992 an agreement with the Instituto Ecuatoriano de Electrificacion strengthened the monitoring of Tungurahua and Cotopaxi volcanoes with real-time SP seismic networks and EDM lines. Thus, background activity levels became established, which was helpful because of the onset of the 1999 eruptive activity at Tungurahua and Guagua Pichincha. These eruptions had a notable impact on Baños and Quito. Unrest at Cotopaxi volcano was detected in 2001-2002, but waned. In 2002 Reventador began its eruptive period which continues to the present and is closely monitored by the IG. In 2006 permanent seismic BB stations and infrasound sensors were installed at Tungurahua and Cotopaxi under a cooperative program supported by JICA, which allowed us to follow Tungurahua's climatic eruptions of 2006 and subsequent eruptions up to the present. Programs supported by the Ecuadorian Secretaria Nacional de Ciencia y Tecnologia and the Secretaria Nacional de Planificacion resulted in further expansion of the IG's monitoring infrastructure. Thermal and video imagery, SO2 emission monitoring, geochemical analyses, continuous GPS and tiltmeters, and micro-barometric surveillance have been incorporated. Sangay, Soche, Ninahuilca, Pululahua, and Fernandina, Cerro Azul, Sierra Negra, and Alcedo in the Galapagos Islands are now monitored in real-time. During this time, international cooperation with universities (Blaise Pascal & Nice-France, U. North Carolina, New Mexico Tech, Uppsala-Sweden, Nagoya, etc.), and research centers (USGS & UNAVCO-USA, IRD-France, NIED-Japan, SGC-Colombia, VAAC, MIROVA) has introduced

    Instituto Traumatológico developed an innovative project to gather clinical data in a digital format, thus generating the information necessary to make decisions. The ultimate goal of the project is to provide our patients with the best attention possible. The impact of incorporating health care informatics to a hospital's daily routine is profound, especially when those who are in charge of change have not learned about this topic or encouraged their students to incorporate new technologies to their work. The results of this project become even more significant when it is implemented in Latin American public hospitals, where the resources invested in technology are scarce. The success of this project could be considered a case of study for the region and the country. Although many efforts and resources have been invested in systematizing information, few cases have shown positive results. This project started with the systematization of the process of attention at the Emergency Department and the adaptation of the Emergency Information System. Once the implementation of this system was over, the project was applied to install the Polyclinic Information System, and Hospitalization Information Systems. The Electronic Health Record includes interfaces for specialties such as upper limbs, spine, hips and lower limbs, which makes it easier for specialists to handle the required information. The large amount of recollected data has been translated into statistic charts and indicators, which support the administration processes that take place in intermediate and superior areas of the Institute.

    Electroconvulsive therapy (ECT) is a useful option for the treatment of certain psychiatric illnesses. Its efficacy and few side effects make it an important therapeutic alternative in the management of the patient with major depression. This study describes the clinical experience with ECT at the Instituto Mexicano de Psiquiatría. We retrospectively evaluated the clinical records of patients treated with ECT during the period of April 1990 to June 1994. A total of 55 patients were included in the analysis, the mean age was 42.4 +/- 17.2 years old. Diagnostic categories treated were major depression (43.6%), non-affective psychotic disorders (30.9%), mania (12.7%) and other diagnoses (12.7%). A positive response to ECT was found in 74.5% of patients. Subjects with major depression and mania responded significantly better than the rest of the patients (p < 0.01). Psychotic depression was not a predictor of better response. Only 18.1% of subjects had minor complications, all transitory. ECT is a highly effective therapeutic option in the treatment of psychiatric illness, especially in major depression and mania. The use of ECT in a tertiary psychiatric unit in Mexico reflects similar results as described in the international literature.

    The Instituto Mexicano del Seguro Social--always sensitive to the needs of health of the beneficiary population and to the demographic and epidemiological changes of the society--has developed and implemented DiabetlMSS, a program of attention to the diabetic patient. DiabetlMSS organizes care processes based on the needs and values of the patients, through simultaneous activities of individual consultation and group meetings granted by the multidisciplinary health team. These actions and activities are focused to affect patients' lifestyles positively. Through a plan of nutrition, physical activity, self-care and monitoring, this program increases the interaction between patients, by having an exchange of successful experiences about diabetes control. DiabetlMSS was created with the purpose that the patients achieve the metabolic control and identify complications early on, with the perspective of timely intervention that is reflected in the decrease of the catastrophic effects that causes the disease, both for patient's life expectancy and the quality of care provided by the Institute.

    The Instituto Nacional de Enfermedades Neoplásicas was established by the government of Peru as an institution for the treatment of cancer patients in 1939; it has existed under different names until the current title was adopted in 1952. Between 1980 and 1987, attendance increased by 70% and a new and larger facility came into use at the beginning of 1988. This institution has national responsibility for cancer prevention, detection, treatment, education, and research and is currently organizing satellite treatment centers in other parts of the country. More than 80% of the medical staff has been trained in the institute's residency program, the majority of whom received additional postgraduate training in the United States and Europe; 90% of the medical staff hold academic appointments in medical schools. In 1952 the Institute became the first hospital in Peru with a formal postgraduate training system for various medical disciplines, including surgical oncology and medical oncology. So far we have trained about 500 surgical oncologists who are working in all parts of Peru. The Maes-Heller Institute for Cancer Research forms part of the National Cancer Institute complex. Research will be directed mainly toward new diagnostic and therapeutic approaches, multidisciplinary tumor therapy, and large-scale cancer screening. The Institute focuses on early detection and prevention of cancer and is active in breast self-examination education and antismoking campaigns. It enjoys community support evidenced in the women's organization, Adainen, involved in fundraising; 460 women volunteers give at least 4 hr service per week to the Institute. The Institute has grown from 9,000 patients seen per year in its early days to 215,000 attendances in 1986.

    The aim of this study was to evaluate the epidemiological, clinical and laboratorial profile of patients with Baggio-Yoshinari Syndrome (BYS), who underwent internment at the Instituto de Infectologia Emilio Ribas in São Paulo, Brazil, during the period from July 1990 to July 2006. BYS is a new Brazilian tick-borne disease caused by Borrelia burgdorferi sensu lato microorganisms that resembles features of Lyme disease (LD), except for its epidemiological, clinical and laboratorial particularities. From 60 patients' records with positive serology to B. burgdorferi done by ELISA and Western-blotting methods, 19 cases were diagnosed as having BYS, according to criteria adopted at LIM-17 HCFMUSP, the Brazilian Reference Laboratory for the research of BYS. The other 41 remaining patients displayed miscellaneous infections or auto-immune processes. The beginning of symptoms in BYS group varied from one day to six years, from the onset of the disease. Four of 19 patients were included in acute disease stage, and 15 in latent. General unspecific symptoms were identified in almost all cases, with high frequencies of fever (78.9%) and lymphadenomegaly (36.8%). Six patients had skin lesions (31.5%); six arthralgia or arthritis (31.5%) and eight neurological symptoms (42%). Interestingly, two patients showed antibodies directed to B. burgdorferi exclusively in cerebrospinal fluid. Since BYS is a new emergent Brazilian zoonosis and its diagnosis is sometimes complex, all the new knowledge about BYS must be scattered to Brazilian Medical specialists, aiming to teach them how to diagnose this amazing tick-borne disease and to avoid its progression to chronic irreversible sequels.

    In May 2007, the Instituto Carso de la Salud—now Instituto Carlos Slim de la Salud (ICSS)—was endowed with US$500 million to focus on priority health issues in Latin America, notably issues of ‘globalisation and non-communicable diseases’. ICSS was soon criticised, however, on the grounds that its funding was derived from tobacco industry profits and that its founder Carlos Slim Hélu remained an active industry principal. Collaboration with ICSS was said to run counter to the WHO Framework Convention on Tobacco Control. The Institute's then Executive President Julio Frenk disputed these charges. This research employs an archive of tobacco industry documents triangulated with materials from commercial, media, regulatory and NGO sources to examine the financial relations between Slim and the tobacco industry. The paper analyses Slim's continuing service to the industry and role in ICSS. It demonstrates a prima facie conflict of interest between ICSS's health mission and its founder's involvement in cigarette manufacturing and marketing, reflected on ICSS's website as a resounding silence on issues of tobacco and health. It is concluded that the reliance of international health agencies upon the commercial sector requires more robust institutional policies to effectively regulate conflicts of interest. PMID:21088061

    A cross-sectional study that included 100 units of umbilical cord blood (UCB) was conducted to evaluate the minimum criteria of cellularity in UCB units, according to NetCord standards at Instituto Nacional Materno Perinatal in Lima, Peru. The volume, total count of nucleated cells by hematological tests and total number of CD34+ as well as cell viability by flow cytometry were determined. The study revealed that 56% of UCB units do not fulfill the minimum criteria of cellularity to be cryopreserved in an umbilical cord blood bank. Furthermore, the UCB units of newborns who weighed more and were female had a higher volume and cell count. In conclusion, these variables must undoubtedly be considered to optimize the collection of UCB units and obtain greater cell counts that enable the storage of high-quality units in a future umbilical cord blood bank in Peru.

The majority of the patients were in the age range of 50 to 79 years, and 79% were males. The overall observed three year tumor free survival was 85.3%. When survival rate was adjusted for intercurrent disease and second primary tumor death, the 3 year tumor free survival was 92%. Sixty two percent of the patients (17/27) undergoing surgical salvage for recurrence, were controlled. Second primary tumors were seen in 18 patients (6.9%). It is emphasized the importance of close follow up to diagnose as early as possible both the vocal cord recurrence and the second primary tumors.

Dosemeters were placed during a five month period in the nuclear medicine rooms (containing gamma-cameras), injection corridor, patient waiting areas, PET/CT study room, hot lab, waste storage room and corridors next to the hospitalization rooms for patients treated with 131I and 137Cs. High dose values were found at the waste storage room, outside corridor of 137Cs brachytherapy patients and PET/CT area. Ambient dose equivalent rate obtained for the 137Cs brachytherapy corridor is equal to (18.51±0.02)×10-3 mSv/h. Sites with minimum doses are the gamma camera rooms, having ambient dose equivalent rates equal to (0.05±0.03)×10-3 mSv/h. Recommendations have been given to the Department authorities so that further actions are taken to reduce doses at high dose sites in order to comply with the ALARA principle (as low as reasonably achievable).

    The Instituto de Investigaciones Cardiológicas (ININCA) was founded by Alberto C. Taquini in 1944 and directed by him during more than 50 years, until his death in 1998. The Institute was (and still is) dedicated to research in connection with CONICET (National Research Council) and to teaching within the Faculty of Medicine of the University of Buenos Aires. From the very beginning research was centered on hypertension, hypoxia and hemodynamic adaptations, renal physiology and electrolytes, arterial wall, cardiac metabolism, myocardial pharmacology and regulation of the circulation by the central nervous system. On the basis of Taquini's autobiographical notes, the experiments are reported which eventually led to the discovery of hypertensin, angiotensin and their relation with renin, together with the discussions promoted by the diverse hypotheses proposed by both national and international groups of investigators as the mechanism of hypertension. Taquini also played an important role in promoting science at national levels including his role as the first Secretary of Science and Technology from 1968 to 1971. He believed that scientific research is something more than planning and producing, that it also involves creating knowledge. As such he made many contributions to science, formed many disciples, and directed an Institute which is demonstrating its continuity.

    Annular pancreas (AP) is a rare congenital anomaly due to malrotation of the pancreatic ventral yolk. Although it has been described in young and middle age adults it predominates in children. Its clinical picture is that of duodenal obstruction or acute pancreatitis episodes. In this paper we report four cases of AP that were seen at the Instituto Nacional de la Nutricion Salvador Zubiran in Mexico City. Three were females and three were less than twenty years old. In one case the diagnosis was established at birth and the operation done in another hospital. In another patient a diagnosis of pyloric hypertrophy was made and a pyloroplasty was performed. This young man was admitted in our hospital because of abdominal pain and hyperamylasemia. An eighty four year old woman was seen due to abdominal pain, nausea and vomit. In all cases the diagnosis of AP was carried out with radiological studies and confirmed by laparotomy. Surgical procedures consisted of duodenal-duodenal anastomosis in two, sphincteroplasty in one, and gastrojejunoanastomosis in the other. Two patients are asymptomatic, one died in the postoperative period, and one was lost for follow up. These four cases represent all the experience of our institute and correspond to one case in 36,735 admissions.

    We evaluated 500 endoscopic retrograde cholangiopancreatographies (ERCP) performed on 422 patients during a 5-year period in the Gastrointestinal Endoscopy Department, Instituto Nacional de la Nutrición Salvador Zubirán, México, D.F. ERCP combines endoscopic and radiologic techniques in order to obtain high quality opacification of pancreatic and biliary ducts. The rate of success for cannulation was 90%; desired duct opacification was possible in 89%. The most frequent indication for ERCP was to establish the differential diagnosis for jaundice; biliary stones in the common bile duct was the most frequent diagnosis, followed by normal biliary ducts. Pancreatography was normal in 74% of patients. ERCP complications were detected in 5.6%; fever and transient pain was the most common complaint in 1.6%. Mortality attributable to the procedure was 0.8%. From histological corroboration of cases by surgery or postmortem studies, diagnostic sensitivity was 92%, specificity 76%, positive predictive value 96% and a prevalence of 89%. We conclude that ERCP is highly sensitive and specific in diagnosing bilio-pancreatic-duodenal disease. Our results are comparable to other's experiences published throughout the world.

    1985 was a year of inauguration for the Instituto de Astrofísica de Canarias (IAC). In that year its two observatories, the Observatorio del Roque de los Muchachos, on the island of La Palma, (where its 10.4m optical-NIR telescope vies with the world´s major instruments), and the Observatorio del Teide, on the island of Tenerife, as well as its headquarters in La Laguna, Tenerife, were all inaugurated. This young institution has rapidly become the leading research centre for astronomy in Spain and achieved research standards at a European and world level. The 30th anniversary celebrations this year give an opportunity to maximize its already very active outreach programmes. In February two shows, featuring IAC researchers, and with astronomical themes, were shown in the main theatre of the city of La Laguna, and during the year further entertainment, collaborating with Canarian musicians and artists, is planned. Two exhibitions have been designed combining the anniversary with celebrations of the International Year of Light: “Listen to the Universe”, in Tenerife, and “Thirty Journeys around the Sun”, in La Palma, which will be open to the public for most of the year. A new outreach magazine “Parallaxes” will be launched by the IAC, in both paper and digital editions, and will complement the current blog, and news websites of the institute, as well as its communications on Facebook and Twitter. Among the activities being organized in Tenerife will be the formal naming of traffic circles with names of the telescopes at the Observatories. In conjunction with the municipal wine cellars of the local city of Tegueste a new Canarian wine produced by innovative methods and with an astronomical motif on its label, is to be launched during the year. All of these activities are in addition to the somewhat more routine productions of videos on the research lines of the IAC, including exoplanets, solar stellar, and interstellar physics, galaxies, and cosmology.

    The superficial mycoses are very common infectious diseases and therefore are a frequent reason for medical consultation. The aim of this study was to determine the diagnostic frequency of superficial mycoses in the Mycology Department of the Instituto Nacional de Higiene "Rafael Rangel" during 14 years (2001-2014). A retrospective cross-sectional study was performed to review the mycological records of patients with presumptive diagnosis of superficial mycosis. Nails, hairs and epidermal scales were the processed samples. The identification of fungi was performed by macro and microscopic observation of colonies and biochemical and physiological tests, as required of the isolated agent. For the investigation of Malassezia spp. only direct examination was performed. Of the 3 228 samples processed, 1 098 (34%) were positive and their distribution according to the etiological agent was: dermatophytes 79.5%; 10.9% yeasts; non-dermatophytes fungi 5.1% and 4.5% Malassezia spp. The most frequently isolated dermatophyte was Trichophyton rubrum Complex (70.1%), followed by T mentagrophytes complex (15.1%), Microsporum canis (9.4%) and Epidermophyton floccosum (4%). The most frequent ringworms Were: Tinea unguium (66.8%), followed by Tineapedis (16.4%) and Tinea capitis (8.1%). Candida parapsilosis complex (37.5%) was the most frequently isolated yeast and Fusarium spp. (53.6%) was the most isolated among non-dermatophyte fungi, followed by Aspergillus spp. (19.6%) and Acremonium spp. (10.7%). The identification of the etiological agent is essential to guide appropriate treatment. This study constitutes an important contribution to the knowledge of the epidemiology of superficial mycoses in our country.

    Testing problems in diagnosing human T-lymphotropic virus (HTLV) infection, mostly HTLV-II, have been documented in HIV/AIDS patients. Since December 1998, the Immunology Department of Instituto Adolfo Lutz (IAL) offers HTLV-I/II serology to Public Health Units that attend HTLV high-risk individuals. Two thousand, three hundred and twelve serum samples: 1,393 from AIDS Reference Centers (Group I), and 919 from HTLV out-patient clinics (Group II) were sent to IAL for HTLV-I/II antibodies detection. The majority of them were screened by two enzyme immunoassays (EIAs), and confirmed by Western Blot (WB 2.4, Genelabs). Seven different EIA kits were employed during the period, and according to WB results, the best performance was obtained by EIAs that contain HTLV-I and HTLV-II viral lysates and rgp21 as antigens. Neither 1st and 2nd, nor 3rd generation EIA kits were 100% sensitive in detecting truly HTLV-I/II reactive samples. HTLV-I and HTLV-II prevalence rates of 3.3% and 2.5% were detected in Group I, and of 9.6% and 3.6% in Group II, respectively. High percentages of HTLV-seroindeterminate WB sera were detected in both Groups. The algorithm testing to be employed in HTLV high-risk population from São Paulo, Brazil, needs the use of two EIA kits of different formats and compounds as screening, and because of high seroindeterminate WB, may be another confirmatory assay.

The article describes the development of the Public Health Institutes. arising from the introduction and development of scientific and laboratory based medicine and the introduction of vaccination and sanitation with the control of water and food. At about the same time, the discoveries in microbiology and immunology were produced, being the research activities incardinated with the practical advances in the control of products. To cope with the practical needs, Institutions were created with the responsibility of providing smallpox vaccine but incorporating very soon production of sera and other vaccines and water and sanitation control and foods control. At the same time. colonization of countries specially in Africa, South East Asia and explorations in Central America confront the Europeans with new diseases and the need of laboratories where to study them. These circumstances gave rise to the birth of the Central Public Health Laboratories and the National institutes of Health at the beginning of the XX century in many countries. In Spain, the Spanish Civil War was a breaking point in the development of such an institution that finally was reinvented with the creation of the Instituto de Salud Carlos III, in 1986, incorporating research and epidemiological surveillance and control of diseases and also the responsibilities of the Food and Drug Control, lately separated from it.

    The article uses the debate surrounding creation of the Instituto Internacional da Hiléia Amazônica (International Institute of the Hylean Amazon--IIHA) as a point of departure for analyzing the topic of development. We first address post-World War II relations between science and development. Next, we examine the Brazilian government's initiatives in the Amazon during the 1940s and how the IIHA project was received. Lastly, we analyze the controversies ignited in Brazil by Unesco's plan. The IIHA project was a catalyst of the development debate in post-World War II Brazil. The discussions then sparked in Brazil and the project's denouement solidified a development model for the Amazon that even today underpins initiatives taken in the region.

    Research is a main element for human and social development. Under this point of view, it involves particular challenges and opportunities for the so-called "developing countries". An approach for those challenges and opportunities comes from the analysis of two interrelated activities; the training of new researchers and the research development with institutions or researchers which are external to the institution ("collaborative research"). Both activities are essential for the consolidation, widening and updating of the institutional capabilities for scientific production. We present here the experiences of the Instituto de Medicina Tropical "Alexander von Humboldt" of the Universidad Peruana Cayetano Heredia, in relation to the training of new researchers, we discuss the four elements we consider key for this process; the promotion of stimulating environments for research, the proactive identification of fellows, the complementary advice and networks consolidation; and we analyze three successful models of international collaboration for the training of new researchers under different institutional approaches.

    Coccidioidomycosis is an emerging fungal disease in Brazil; adequate maintenance and authentication of Coccidioides isolates are essential for research into genetic diversity of the environmental organisms, as well as for understanding the human disease. Seventeen Coccidioides isolates maintained under mineral oil since 1975 in the Instituto de Medicina Tropical de São Paulo (IMTSP) culture collection, Brazil, were evaluated with respect to their viability, morphological characteristics and genetic features in order to authenticate these fungal cultures. Only five isolates were viable after almost 30 years, showing typical morphological characteristics, and sequencing analysis using Coi-F and Coi-R primers revealed 99% identity with Coccidioides genera. These five isolates were then preserved in liquid nitrogen and sterile water, and remained viable after two years of storage under these conditions, maintaining the same features.

    The development of scientific health research requires a sustained and articulated research system that is consistent with the research priorities, as well as both internal and external funding, and availability of competent human resources. The Mining Canon, a constitutional right, has been partly used to foster applied scientific research in public universities (PU). In addition, the National Health Institute (INSTITUTO NACIONAL DE SALUD - INS) is devoted, among others, to promoting, managing and disseminating health research development at a national level. As part of these activities, a technical team was created to provide technical assistance to PU for research development using Mining Canon funds by making local adjustments to research protocols promoted by the INS and assumed by the professors-researchers at the Universities. This article aims at describing the reality of research at Peruvian public universities that have access to Mining Canon funds, as well as to elaborate on the work the INS is carrying out in order to strengthen research capabilities, starting with the development of research proposals that could potentially be funded by the Mining Canon.

    The purpose of this study was to determine the frequency of different Central Nervous System Tumors (CNST) diagnosed at the Instituto Nacional de Neurología y Neurocirugía (National Institute of Neurology and Neurosurgery) from Mexico City over a 10-year period (1990 to 1999) by means of a hospital survey. This institute is a reference hospital that provides medical attention to a very high number of adult neurological patients every year (approximately 6,000 new patients per year besides emergency cases). From a total number of 2,041 CNST cases, we found that the most frequent tumors were those affecting the neuroepithelial tissue (32.8 %), followed by tumors of the anterior pituitary gland (26.2 %) and tumors of the meninges and similar tissues (24.1 %). In both, male and female patients the higher frequency of CNST was found in patients whose age ranged from 25 to 44 years, and CNST were slightly more frequent in women than in men. Most of the CNST patients lived in the southern districts of Mexico City, it could be because of the great number of people living in the southern districts of the city, or perhaps due to the presence of certain yet unidentified environmental carcinogenic substance in this area. Since CNST are among the more frequent malignant neoplasms, it is necessary to improve the registration system to include frequency, prevalence, incidence and mortality of these diseases in Mexico, in order to plan health policies like in developed countries.

    In order to describe the clinical-pathological characteristics of the cases of Eccrine Porocarcinoma (EP) found in the Instituto Nacional de Enfermedades Neoplásicas (INEN), a cross-sectional study was carried out, including all EP cases recorded between 1998 and 2009. A revision of the clinical-pathological records indentified and a new reading of the pathology slides of the cases found were performed. 19 EP cases were found, the median age of which was 64 years (range: 37-98). EP was primarily found on male patients (57.9%) and was most commonly located on the foot (21.1%), followed by the head, thorax and thigh (15.8%, respectively). In one case, EP was located on the gluteal region, and showed an unusually invasive behavior and rectal involvement. We conclude that EP is a rather uncommon entity in Peru. Its most common location is on the foot and it affects mostly male patients for the most part.

    The quality of care has always been a subject of interest to the Instituto Nacional de la Nutrición "Salvador Zubirán", in order to improve its services. This interest led to the present survey which aims to evaluate the patient's global satisfaction and to identify specific problems susceptible of improvement. One hundred and seventy-one patients or relatives attending eight different services of the Institute were interviewed. Opinions about the following aspects were explored by means of service-specific questionnaires: sociodemographic characteristics, satisfaction with care, waiting periods, patient-personnel relationship, hospital environment, food quality, drug availability and costs. Results of the survey show a high level of satisfaction with the services provided, i.e. 33% of the patients considered it good, and 64% excellent. However, and in agreement with other reports, this high level of satisfaction does not necessarily reflect an absence of problems, i.e. long waiting periods, insufficient restrooms, failures in getting information about their health status, and occasional absence of drugs in the pharmacy were identified. Continuation of this kind of surveys in our setting leads not only to the identification of problems, but also to the evaluation of the impact that resulting measures may have on the patient's satisfaction.

    Comparison of clinical and autopsy findings of the cases studied between 1984 and 1988, were made at the Department of Pathology of the Instituto Nacional de la Nutricion Salvador Zubiran in Mexico City. The goal was to determine the accuracy of clinical diagnoses. The total number of cases was 429. A decreasing number of autopsies as a function of time was observed. Thus, in 1985, 34.65% of the deaths was autopsied, whereas in 1988, the number dropped to 21.16%, overall mean of 27.31%. In 229 autopsies (53.8%), 353 findings of clinical significance were found; of these, 86 were in the main diagnoses and 267 in the causes of death. There were 171 overdiagnoses with therapeutic implications, 38 in the main diagnoses and 133 in the causes of death. Overdiagnoses and underdiagnoses were most common in infectious diseases, followed by respiratory and digestive diseases, while endocrinologic and rheumatologic diseases had the highest diagnostic concordance. It was also found that the diagnostic accuracy did not improve with time of hospitalization. A brief analyses of the probable causes of the decrease in the number of autopsies is made. It is concluded that, in spite of the great advances in clinical and technological knowledge, the high frequency of disagreements between clinical and anatomical diagnoses, indicate that autopsy continues playing a key role in the quality control of medical practice. This justifies by itself the performance of necropsies.

    By 1960, México's Manicomio General (General Asylum) could no longer fulfill the functions for which it was created so implementation of the so-called Castañeda Operation began, an initiative designed to close down and relocate psychiatric patients to other institutions. At that time, Dr. Manuel Velasco-Suárez was in charge of the General Direction of Neurology, Mental Health and Rehabilitation, and planned to create the Institute of Neurology on a site he already possessed for its construction. The Asylum was a dependency of the aforementioned Direction and Velasco- Suárez decided that some patients at the Castañeda could be moved to the old hacienda house that stood on that terrain. Thus was born the Bernardino Álvarez Farm Hospital. A year later, in 1961, the Farm School for the Weak-Minded, also named Bernardino Álvarez was established there as well. This paper examines the history of these two institutions as antecedents to the Instituto Nacional de Neurología y Neurocirugía.

    Historians of science have yet to study the process by which the oceanographic sciences emerged and became firmly established in Brazil. The main goal of this article is to offer a preliminary analysis of this process by focusing on the contribution of the Instituto Paulista de Oceanografia (Paulista Institute of Oceanography), Brazil's first institution for oceanographic research; it was founded in 1946 and became part of the University of São Paulo in 1951, at which time it was renamed the Instituto Oceanográfico da Universidade de São Paulo (Oceanographic Institute of the University of São Paulo). The analysis centers on the role of three scientists who were on the facility's early research staff: Wladimir Besnard, Ingvar Emilsson, and Marta Vannucci.

    Background The objective of this article is to present the frequency of cancer in Mexican children who were treated in the hospitals of the Instituto Mexicano del Seguro Social in Mexico City (IMSS-MC) in the period 1996–2001. Methods The Registry of Cancer in Children, started in 1996 in the IMSS-MC, is an on-going, prospective register. The data from 1996 through 2001 were analyzed and the different types of cancer were grouped according to the International Classification for Cancer in Children (ICCC). From this analysis, the general and specific frequencies by age and by sex were obtained for the different groups of neoplasms. Also, the frequency of the stage of the disease that had been diagnosed in cases of children with solid tumors was obtained. Results A total of 1,702 new cases of children with cancer were registered, with the male/female ratio at 1.1/1. Leukemias had the highest frequency with 784 cases (46.1%) and, of these, acute lymphoblastic leukemias were the most prevalent with 614 cases (78.3%). Thereafter, in descending order of frequency, were tumors of the central nervous system (CNST) with 197 cases (11.6%), lymphomas with 194 cases (11.4%), germinal cell tumors with 110 cases (6.5%), and bone tumors with 97 cases (5.7%). The highest frequency of cancer was found in the group of one to four year-olds that had 627 cases (36.8%). In all the age groups, leukemias were the most frequent. In the present work, the frequency of Hodgkin's disease (~4%) was found to be lower than that (~10%) in previous studies and the frequency of tumors of the sympathetic nervous system was low (2.3%). Of those cases of solid tumors for which the stage of the disease had been determined, 66.9% were diagnosed as being Stage III or IV. Conclusions The principal cancers in the children treated in the IMSS-MC were leukemias, CNST, and lymphomas, consistent with those reported by developed countries. A 2.5-fold reduction in the frequency of Hodgkin's disease was found

    The concentrations of 3 oxides and 29 elements in 7 National Bureau of Standards (NBS) and 3 Instituto de Pesquisas Techno16gicas (IPT) reference clay samples were etermined by instrumental neutron activation analysis. The analytical work was designed to test the homogeneity of constituents in three new NBS reference clays, NBS-97b, NBS-98b, and NBS-679. The analyses of variance of 276 sets of data for these three standards show that the constituents are distributed homogeneously among bottles of samples for 94 percent of the sets of data. Three of the reference samples (NBS-97, NBS-97a, and NBS-97b) are flint clays; four of the samples (NBS-98, NBS-98a, NBS-98b, and IPT-32) are plastic clays, and three of the samples (NBS-679, IPT-28, and IPT-42) are miscellaneous clays (both sedimentary and residual). Seven clays are predominantly kaolinite; the other three clays contain illite and kaolinite in the approximate ratio 3:2. Seven clays contain quartz as the major nonclay mineral. The mineralogy of the flint and plastic clays from Missouri (NBS-97a and NBS-98a) differs markedly from that of the flint and plastic clays from Pennsylvania (NBS-97, NBS-97b, NBS-98, and NBS-98b). The flint clay NBS-97 has higher average chromium, hafnium, lithium, and zirconium contents than its replacement, reference sample NBS-97b. The differences between the plastic clay NBS-98 and its replacement, NBS-98b, are not as pronounced. The trace element contents of the flint and plastic clays from Missouri, NBS-97a and NBS-98a, differ significantly from those of the clays from Pennsylvania, especially the average rare earth element (REE) contents. The trace element contents of clay sample IPT-32 differ from those of the other plastic clays. IPT-28 and IPT-42 have some average trace element contents that differ not only between these two samples but also from all the other clays. IPT-28 has the highest summation of the average REE contents of the 10 samples. The uranium content of NBS-98a, 46

The analysis of the documents has considered two periods: the first one, from 1956 to 1971, is characterized by the foundation of the institute and its first training activities; the second period goes from 1972 to 1994, which is characterized by the consolidation of the institute's organizational structure and the presence of educational concepts in its training activities. Training focused on technical aspects and recurrently alluded to hygiene and organization. Discussions on the training of school cafeteria staff members should define what kind of workers is expected before defining what skills and abilities they are expected to develop.

    Abstract The former Instituto de Investigação Científica Tropical-IICT (Lisbon, Portugal), recently integrated into the University of Lisbon, gathers important natural history collections from Portuguese-speaking African countries. In this study, we describe the bird collection from the Democratic Republic of São Tomé and Príncipe, which was fully taxonomically checked and georeferenced. The IICT bird collection contains 5598 specimens, of which 559 are from São Tomé and Príncipe, representing 85 taxa, including 19 endemic species and 13 endemic subspecies of birds. The specimens were collected between 1946 and 1973, although 43% of the records are from 1954 and 45% are from 1970. The geographic distribution of samples covers the whole territory, with a higher number of records from São Tomé than from Príncipe. The districts with highest number of records are Pagué (equivalent to Príncipe Island), and Água Grande and Mé-Zochi on São Tomé. Despite the relatively low number of specimens per taxon, the importance of the collection is considerable due to the high number of endemic and threatened species represented. Furthermore, it adds valuable information to the GBIF network, especially for a country whose two islands are each an Endemic Bird Area and for which substantial gaps in ornithological knowledge remain.

    Background Osteoarthritis (OA) is one of the main causes of disability worldwide, especially in persons >55 years of age. Currently, controversy remains about the best therapeutic alternative for this disease when evaluated from a cost-effectiveness viewpoint. For Social Security Institutions in developing countries, it is very important to assess what drugs may decrease the subsequent use of medical care resources, considering their adverse events that are known to have a significant increase in medical care costs of patients with OA. Three treatment alternatives were compared: celecoxib (200 mg twice daily), non-selective NSAIDs (naproxen, 500 mg twice daily; diclofenac, 100 mg twice daily; and piroxicam, 20 mg/day) and acetaminophen, 1000 mg twice daily. The aim of this study was to identify the most cost-effective first-choice pharmacological treatment for the control of joint pain secondary to OA in patients treated at the Instituto Mexicano del Seguro Social (IMSS). Methods A cost-effectiveness assessment was carried out. A systematic review of the literature was performed to obtain transition probabilities. In order to evaluate analysis robustness, one-way and probabilistic sensitivity analyses were conducted. Estimations were done for a 6-month period. Results Treatment demonstrating the best cost-effectiveness results [lowest cost-effectiveness ratio $17.5 pesos/patient ($1.75 USD)] was celecoxib. According to the one-way sensitivity analysis, celecoxib would need to markedly decrease its effectiveness in order for it to not be the optimal treatment option. In the probabilistic analysis, both in the construction of the acceptability curves and in the estimation of net economic benefits, the most cost-effective option was celecoxib. Conclusion From a Mexican institutional perspective and probably in other Social Security Institutions in similar developing countries, the most cost-effective option for treatment of knee and/or hip OA would be celecoxib.

    The breeding sites of Culicoides pachymerus are described for the first time in western Boyacá Province, Colombia, where this species is a public health problem. In addition to being a nuisance due to its enormous density and its high biting rates, C. pachymerus cause dermatological problems in the human population. Analysis of microhabitats by the sugar flotation technique and the use of emergence traps allowed us to recover 155 larvae of Culicoides spp and 65 adults of C. pachymerus from peridomiciliary muddy substrates formed by springs of water and constant rainwater accumulation. These important findings could aid in the design of integrated control measures against this pest.

    One of the most diverse vertebrate communities is found on tropical coral reefs. Coral-reef fishes are not only remarkable in color and shape, but also in several aspects of physiological performance. Early in life, at the end of the pelagic larval stage, coral-reef fishes are the fastest swimmers of all fishes in relation to body size, and show the highest specific rates of maximum oxygen uptake. Upon settling on the reef, coral-reef fishes have to adopt a demersal lifestyle, which involves coping with a habitat that can become severely hypoxic, and some fishes may even have to rely on air breathing when their coral homes become air exposed. Oxygen availability appears to be a major ambient selection pressure, making respiratory function a key factor for survival on coral reefs. Consequently, hypoxia tolerance is widespread among coral-reef fishes. Hypoxia can even be a factor to gamble with for those fishes that are mouthbrooders, or a factor that the coral inhabitants may actively seek to reduce by sleep-swimming at night. Here, we summarize the present knowledge of the respiratory ecophysiology of coral-reef teleosts. From an ecophysiological perspective, the coral reef is an exciting and largely unexplored system for testing existing hypotheses and making new discoveries.

    A relatively high leishmanial infection rate was found in the phlebotomine sandfly Lutzomyia longipalpis collected from three villages of the Los Yungas region (Department of La Paz, Bolivia). 2,578 female sandflies were dissected. In three houses surveyed in Santa Barbara promastigote infection rates of Lu. longipalpis were 4.2, 2.2 and 3.2% respectively. Anatomical localization of the infection in the insect, and biochemical characterization of the strains indicate that the parasite belongs to the Leishmania donovani complex. The geographical area and the biotopes of Lu. longipalpis are discussed in relation to the vector-parasite relationship.

    The area of the Dunas da Joaquina, in Santa Catarina island, contains one of the most important remnants of restinga habitat in Santa Catarina State, southern Brazil. In December 2003, a fire occurred in a portion of this area, affecting most of the vegetation, including the bromeliad community. In this study, the density of individuals and the diet composition of the bromelicolous treefrog Scinax cf. alter were compared between the area affected by the fire and an adjacent unburned area. One-hundred-and-fifty-eight ground bromeliads (Vriesea friburguensis) were dissected and searched for the presence of treefrogs among their leaves. We found 30 frogs in 29.5% (23/78) of the bromeliads from the unburned site, with a mean of 1.3 frogs per rosette, and 15 frogs in 12.5% (10/80) of the bromeliads from the burned site, with a mean of 1.6 frogs per rosette. Eight (27%) of the frogs from the unburned site and eleven (73%) of those from the burned site had empty stomachs. Frogs from the burned site also contained less prey per stomach than those from the unburned site. The data suggest that the fire has negatively affected the local population of Scinax cf. alter, though it is possible that the population can recover.

    The sand fly Lutzomyia longipalpis is the main vector of Leishmania (L.) infantum (Nicolle), the causative agent of American visceral leishmaniasis (AVL) in the New World. Male Lu. longipalpis have secretory glands which produce sex pheromones in either abdominal tergites 4 or 3 and 4. These glands are sites of sex pheromone production and each pheromone type may represent true sibling species. In Latin America, apart from Lu. pseudolongipalpis Arrivillaga and Feliciangeli from Venezuela, populations of Lu. longipalpis s.l. can be identified by their male-produced sex pheromones: (S)-9-methylgermacrene-B, 3-methyl-α-himachalene and the two cembrenes, 1 and 2. In this study, we present the results of a coupled gas chromatography - mass spectrometry analysis of the pheromones of males Lu. longipalpis captured in an endemic area of visceral leishmaniasis in Asunción, Paraguay. Our results show that Lu. longipalpis from this site produce (S)-9-methylgermacrene-B which has also been found in Lu. longipalpis from different areas of Brazil, Colombia and Central America.

    This article describes the general objectives of the Regional Laboratory Network for Surveillance of Invasive Fungal Infections and Antifungal Susceptibility in Latin America. Formation of the Network was coordinated by the Essential Medicines, Vaccines, and Health Technologies Unit of the Pan American Health Organization, with the technical and financial support of the National Center for Microbiology of the Carlos III Health Institute (Spain), and the technical support of the Microbiology Department of the Dr. C. Malbrán National Institute on Infectious Diseases (Argentina) and the Microbiology Unit of the Parasitology Service of the Adolfo Lutz Institute (Brazil). The Network's principle objectives are epidemiological surveillance of invasive fungal infections through detection of antifungal resistance and identification of emergent, invasive fungal infections; establishment of norms and common protocols for early diagnosis of mycoses; and strengthening coordination, communications, and transference mechanisms among countries. The Network must be gradually implemented and must include staff training, a systematic process for sharing technology, evaluation of diagnostic techniques, identification of fungal species, and standardized tests for antifungal susceptibility.

    The seasonal distribution of Lutzomyia longipalpis was studied in two forested and five domiciliary areas of the urban area of Campo Grande; MS, from December 2003 to November 2005. Weekly captures were carried out with CDC light traps positioned on ground and in the canopy inside a residual forest and on the edge (ground) of a woodland and in at least one of the following ecotopes in peridomiciles-a cultivated area, a chicken coop, a pigsty, a kennel, a goat and sheep shelter and an intradomicile. A total of 9519 sand flies were collected, 2666 during the first year and 6853 during the second. L. longipalpis was found throughout the 2-year period, presenting smaller peaks at intervals of 2-3 months and two greater peaks, the first in February and the second in April 2005, soon after periods of heavy rain. Only In one of the woodlands was a significant negative correlation (p<0.05) between the number of insects and temperature during the first year and the climatic factors (temperature, RHA and rain) was observed. In the domiciliary areas in four domiciles some positive correlations (p< or =0.05) occurred in relation to one or more climatic factors; however, the species shows a clear tendency to greater frequency (72%) in the rainy season than in the dry (28%). Thus, we recommend an intensification of the VL control measures applied in Campo Grande, MS, during the rainy season with a view to reducing the risk of the transmission of the disease.

    Urban increase of visceral leishmaniasis (VL) in Brazil is associated with the adaptation of its vector, Lutzomyia longipalpis, to environments modified by humans. The present study reports the results of an entomological monitoring of L. longipalpis and the effect of environmental variables on its population density. Sandflies were captured in the municipality of Mossoró, State of Rio Grande do Norte, Northeastern Brazil, from January 2005 to December 2006. Two CDC light traps were placed monthly for four consecutive nights in the peridomicile of selected households. Data analysis was based on the chi-square test and linear regression. A total of 2,087 sandflies were captured, 99.86% of which were L. longipalpis. A higher proportion of females were captured (p < 0.05). Monthly analysis of the variables temperature, relative humidity and rainfall did not show a significant influence on population density. However, there were seasonal differences: approximately 70% of sand flies were captured during the rainy season (p < 0.05). The predominant species, L. longipalpis, is present in substantial number, representing a public health risk. Therefore, because of higher prevalence during the rainy season, we recommend intensified VL control measures before and during this season to reduce the risk of disease transmission.

    The influence of altitude and latitude on some structure sizes of Lutzomyia intermedia was noted; several structures of insects collected in higher localities were greater, according to Bergmann's rule. This influence was more remarkable in two localities of the State of Espírito Santo, probably due to greater differences in altitude. Comparing insects from different latitudes, more differences were noted in comparisons of insects from low altitude localities than in those of material from higher altitudes. The small number of differences between insects collected in July and in December does not indicate a defined influence of season and temperature on the size of adults. The possible epidemiological implications of these variations are discussed.

    The aim of this study was to identify potential blood feeding sources of L. (L.) longipalpis specimens from populations in Northeastern Brazil, endemic areas of American Visceral Leishmaniasis (AVL) and its correlation with the transmission of L. (L.) i. chagasi. The ELISA technique was applied using bird, dog, goat, opossum, equine, feline, human, sheep, and rodent antisera to analyze 609 females, resulting in an overall positivity of 60%. In all municipalities, females showed higher positivity for bird followed by dog antiserum and sand fly specimens were also positive for equine, feline, human, sheep, goat, opossum, and rodent antisera. The finding for 17 combinations of two or three types of blood in some females corroborates the opportunistic habit of this sand fly species. The results demonstrating the association between L. (L.) longipalpis and opossum suggest the need for further evaluation of the real role of this synanthropic mammal in the eco-epidemiology of AVL. PMID:22315621

    The life cycle of vectors and the reservoirs that participate in the chain of infectious diseases have a strong relationship with the environmental dynamics of the ecosystems in which they live. Oscillations in population abundance and seasonality of insects can be explained by factors inherent in each region and time period. Therefore, knowledge of the relationship and influence of environmental factors on the population of Lutzomyia longipalpis is necessary because of the high incidence of visceral leishmaniasis (VL) in Brazil. This study evaluates the influence of abiotic variables on the population density and seasonal behavior of L. longipalpis in an urban endemic area of VL in Brazil. The sand fly captures were performed every two months between November, 2009 and November, 2010 in the peridomicile of 13 randomly selected residences. We captured 1,367 specimens of L. longipalpis, and the ratio of male/female flies was 2.86:1. The comparison of the total male specimens in the two seasons showed a statistical difference in the wet season, but there was no significant difference when considering the total females. With respect to climatic variables, a significant negative association was observed only with wind speed. During periods of high wind speeds, the population density of this vector decreased. The presence of L. longipalpis was found in all months of the study with bimodal behavior and population peaks during the wet season.

    Nutrient digestion and absorption after blood feeding are important events for Lutzomyia longipalpis, which uses these nutrients to produce eggs. In this context, the pH inside the digestive tract is an important physiological feature as it can markedly influence the digestive process as well as interfere with Leishmania development in infected phlebotomines. It was described previously that unfed females have an acidic midgut (pH 6). In this study, the pH inside the midgut of blood-fed females was measured. The abdominal midgut (AM) pH varied from 8.15+/-0.31 in the first 10 h post-blood meal to 7.7+/-0.17 after 24 h. While the AM was alkaline during blood digestion, the pH in the thoracic midgut (TM) remained acidic (5.5-6.0). In agreement with these findings, the enzyme alpha-glucosidase, which has an optimum pH of 5.8, is mainly encountered in the acidic TM. The capacity of unfed females to maintain the acidic intestinal pH was also evaluated. Our results showed the presence of an efficient mechanism that maintains the pH almost constant at about 6 in the midgut, but not in the crop. This mechanism is promptly interrupted in the AM by blood ingestion. RT-PCR results indicated the presence of carbonic anhydrase in the midgut cells, which apparently is required to maintain the pH at 6 in the midgut of unfed females. Investigations on the phenomenon of alkalization observed after blood ingestion indicated that two mechanisms are involved: in addition to the alkalization promoted by CO2 volatilization there is a minor contribution from a second mechanism not yet characterized. Some inferences concerning Leishmania development and pH in the digestive tube are presented.

    Amphibians are hosts for a wide variety of ecto- and endoparasites, such as protozoans and parasitic worms. Naididae is a family of Oligochaeta whose species live on a wide range of substrates, including mollusks, aquatic macrophytes, sponges, mosses, liverworts, and filamentous algae. However, some species are known as endoparasitic from vertebrates, such as Dero (Allodero) lutzi, which is parasitic of the urinary tracts of frogs, but also have a free-living stage. Specimens in the parasitic stage lack dorsal setae, branchial fossa, and gills. Here we report the occurrence of D. (A.) lutzi associated with anuran Scinax fuscovarius from Semi-deciduous Atlantic Rain Forest in southern Brazil. The study took place at the Caiuá Ecological Station, Diamante do Norte, Paraná, southern Brazil. Seven specimens of S. fuscovarius were examined for parasites but only one was infected. Parasites occurred in ureters and urinary bladder. Previous records of this D. (A.) lutzi include the Brazilian States of Santa Catarina, São Paulo, Rio de Janeiro, and Minas Gerais, as well as Cuba and North America. This is a new locality record for this species in Brazil. Reports of Dero (Allodero) lutzi are rare, due to difficulty of observation, and such events are restricted only the fortuitous cases. It is important to emphasize the necessity of future studies, which are fundamental to the understanding of biological and ecological aspects of this species.

    São Paulo is the most populous Brazilian state and reports the largest number of tuberculosis cases in the country annually (over 18,500). This study included 193 isolates obtained during the 2nd Nationwide Survey on Mycobacterium tuberculosis Drug Resistance that was conducted in São Paulo state and 547 isolates from a laboratory based study of drug resistance that were analyzed by the Mycobacteria Reference Laboratory at the Institute Adolfo Lutz. Both studies were conducted from 2006 to 2008 and sought to determine the genetic diversity and pattern of drug resistance of M. tuberculosis isolates (MTC) circulating in São Paulo. The patterns obtained from the spoligotyping analysis demonstrated that 51/740 (6.9%) of the isolates corresponded to orphan patterns and that 689 (93.1%) of the isolates distributed into 144 shared types, including 119 that matched a preexisting shared type in the SITVIT2 database and 25 that were new isolates. A total of 77/144 patterns corresponded to unique isolates, while the remaining 67 corresponded to clustered patterns (n = 612 isolates clustered into groups of 2–84 isolates each). The evolutionarily ancient PGG1 lineages (Beijing, CAS1-DEL, EAI3-IND, and PINI2) were rarely detected in São Paulo and comprised only 13/740, or 1.76%, of the total isolates; all of the remaining 727/740, or 98.24%, of the MTC isolates from São Paulo state were from the recent PGG2/3 evolutionary isolates belonging to the LAM, T, S, X, and Haarlem lineages, i.e., the Euro-American group. This study provides the first overview of circulating genotypes of M. tuberculosis in São Paulo state and demonstrates that the clustered shared types containing seven or more M. tuberculosis isolates that are spread in São Paulo state included both resistant and susceptible isolates.

    Purpose To report the outcomes on the Boston Type 1 Keratoprosthesis at our institution. Design Retrospective analysis case series. Participants We analyzed 54 eyes of 53 patients who previously underwent Boston Type 1 Keratoprosthesis surgery at our institution from July 2006 to March 2011. Methods Preoperative and postoperative parameters were collected and analyzed. Main outcome measures Visual acuity and keratoprosthesis stability. Results Common preoperative diagnoses were penetrating keratoplasty failure in 49 eyes (90.7%), chronic keratitis in 2 eyes (3.7%), ocular cicatricial pemphigoid in 1 eye (1.85%), Stevens Johnson syndrome in 1 eye (1.85%) and corneal vascularization in 1 eye (1.85%). Additionally, 40 eyes (74%) had preoperative glaucoma, and an Ahmed valve was implanted in 55% of them. Preoperative BCVA ranged from 20/200 to light perception. At an average follow-up of 20.15 months ± 12.7 (range, 1–56), postoperative vision improved to ⩾20/200 in 18 eyes (33.3%) and ⩾20/50 in 4 eyes (7.4%). The graft retention was 96%. Conclusions The Boston Type 1 keratoprosthesis is a valid option for high-risk patients. The design improvements in the Boston keratoprosthesis, as well as the daily implementation of the therapeutic methods, have notably diminished occurrence of the most serious complications, such as corneal necrosis and endophthalmitis. As such, glaucoma and its subsequent complications now stand as the most prevalent prognostic factor in the long term. PMID:23960937

    Introducción: la razón de muerte materna (RMM) ha disminuido lentamente, no obstante que la OMS se propuso reducirla en un 75 % en el período de 1990 a 2015. Por esto es necesario continuar con el análisis de las causas para reforzar e innovar líneas de acción y así disminuir las muertes maternas en nuestro país. Métodos: estudio retrospectivo en el que se incluyeron casos de muerte materna que ocurrieron de 2009 a 2012, por causa directa e indirecta. La información se obtuvo del expediente de muerte materna, el cual es un documento oficial del IMSS. La definición de muerte materna utilizada fue la emitida por la OMS. Las muertes indirectas se agruparon según la décima revisión de la Clasificación Internacional de Enfermedades (CIE-10). Se utilizó estadística descriptiva. Resultados: la RMM en el IMSS ha disminuido en forma lenta pero constante, pues en el 2012 se obtuvo la RMM más baja en la institución (26.4). Sin embargo, la preeclampsia severa-eclampsia y la hemorragia obstétrica ocuparon el primero y segundo lugar. Como causa indirecta, las enfermedades del sistema cardiovascular, y las neoplasias malignas ocuparon los primeros lugares sin subestimar las cifras de las patologías respiratorias, digestivas y endocrinas. Conclusiones: es necesario proseguir con los esfuerzos para disminuir la RMM en todos los niveles de atención médica. Es prioritario continuar con la educación y consejería preconcepcional a mujeres en edad fértil y fortalecer las acciones en la planificación familiar.

    Introducción: dado que el pronóstico de infarto del miocardio con elevación del segmento ST (IMCEST) depende de su manejo inmediato y de las medidas de prevención secundaria, el no seguir las recomendaciones actuales impide mejorar las expectativas de la población afectada por este padecimiento. El objetivo es describir el perfil clínico-epidemiológico y el proceso de atención del IMCEST en un hospital de tercer nivel. Métodos: se analiza la información clínica, la estratificación de riesgo, la terapia de revascularización y los hábitos de prescripción al egreso de los casos con IMCEST atendidos en un año. Resultados: se incluyeron 246 pacientes con edad promedio de 61 años; el 76 % fueron varones. La mayoría (37.3 %) de IMCEST ocurrió entre los 60 y los 69 años. El sedentarismo fue el factor de riesgo predominante. El 81.7 % de los casos tuvo score TIMI de riesgo bajo. El 35 % tuvo isquemia/viabilidad y en todos los cateterizados se demostraron obstrucciones coronarias. El 76 % se revascularizó con stent, principalmente farmacológico (77.5 %). Al egreso más del 90 % de los casos recibió estatina y antiplaquetarios, mientras otras drogas se prescribieron al 64-82 % de los casos. Conclusiones: el IMCEST predomina en hombres sedentarios de la séptima década. Estratificar el riesgo, buscar isquemia/viabilidad residual y revascularizar con stent farmacológico son prácticas comunes; el cumplimiento de recomendaciones basadas en la evidencia es mejor que en el pasado, pero todavía no es óptimo.

    The first renal transplant was done on July 22, 1968 and until December, 2010 a total of 865 procedures have been performed. Immunosuppressive protocols have changing with time: from 1968 to 1984 azathioprine + prednisone plus total radiation in some cases; from 1985 to 1998 cyclosporine + azathioprine + prednisone; in 1998 tacrolimus is used for first time; Mofetil micofenolate was available at 2005 and practically has displaced to azathioprine. As far as possible we use some induction therapy. Primary ESRD etiologies were: unknown (74.9%), glomerulonephritis (9.7%) and diabetic nephropathy (4.2%). Recipient's mean age was 29.9 +/- 11.6 years (12-70) and 35 +/- 9.8 years (18-62) in donors. Analysis group for graft and patient survival included 292 transplants (censured for death with functional graft) with a follow-up of 103 months (CI 95%: 99-108). Survival at 1, 5 and 10 years were: 95, 85 and 60% for graft as well as 100, 94 and 90% for patient. In year 2000 we started to perform renal biopsies at transplant (time zero biopsies), those results have been published and at present are a worldwide reference. In September, 2005 laparoscopic donor nephrectomy is initiated, 180 procedures have been done with excellent results. In year 2006, training in renal transplant acquires the endorsement as a Medicine Posgrade recognized by the UNAM School of Medicine. We have participated in 9 national clinical trials and 6 international multicentric ones. Our renal transplant program offers a good choice for patients with low resources with similar results reported in the literature using current immunosuppressive schemes and surgical procedures. Institutional authorities and humanitarian associations support in addition to participation on investigation studies have been of vital importance.

    The advance in the knowledge and technology is growing quickly and greater quantity, so it is difficult for the health professional to access to whole information that is generated every day on diagnostic and therapeutic strategies more effective, so the clinic practice guidelines (CPG) is a resource to support the updating of the health professional and support them in making clinical decisions. The CPG is also a better support to the manager of health services in making decisions regarding the strategies that have performed for the patient and less risk to the individual and collective health. They also support the response capacity of the medical units and hospitals and guide the planning of services to the optimization of the resources. This paper summarizes the methodology of a national project for the development of GPC coordinated by the Mexican Social Security Institute with the collaboration of more than 1200 health professionals of the institution in a great effort institutional update and make information accessible to the entire health sector, which also defines the steps to upgrade and maintain the updating of knowledge and technology expressed in them.

    The epidemiologic transition moves mortality towards the chronic diseases as the main causes and the elderly groups as their main targets. The Institute Mexican del Seguro Social (IMSS) contributes with 3 of every 10 deaths reported in the country. Mortality rates in men increased from 330.1 x 100,000 in 1990 to 485.4 in 2005. In women rates grew from 249.9 to 405.5 in the same period. Mortality patterns show a mayor contribution by the northern region and are different with regard to sex and age groups. The group under 20 years old have a lower contribution to mortality during the period studied. In the population insured by IMSS, the 60 to 79 age group in both sexes contributes with a major proportion of deaths.

    We present the new system for the evaluation of the medical specialization courses at the IMSS which will substitute in 2005 the one used at present. This system derives from a participative conception of education and has as an axis the development of aptitudes. For participative education, knowledge is the result of the student's elaboration, and not the result of the consumption of information. An aptitude is the conjunction of knowledge, abilities and attitudes in a constant development which gives the bearer experience a growing penetration to understand the problematic situations that challenge him, a greater reach of the decisions and actions performed and progressive pertinence to positively influence the working environment. The new evaluation system is centered in the development of two types of aptitude: the clinical aptitude and the aptitude for the appropriate use of information sources. It has an explanatory and instructions section, as well as four types of forms: (a) evaluation of the aptitudes development through time. (b) Performance of activities (in the service and academic) related with the aptitudes seeking to develop. (c) Evaluation of the academic and working environment, and (d) self evaluation. With the new system of evaluation of the formation of medical specialists we pretend to contribute to the overcoming of the educative labors at the Institute, by orienting the professors' and students' reflection towards the main aspects of learning, as well as promote the criticism and self-criticism.

    Extrinsic allergic alveolitis is an interstitial lung disease caused by exposure to a variety of inhaled antigens. In Mexico, the most frequent form is due to the inhalation of avian antigens, markedly pigeon proteins. Depending on type and time exposure, the disease presents different clinical forms usually characterized by progressive dyspnea, ground glass or reticulonodular images on chest x rays, a restrictive functional pattern, rest hypoxemia worsening with exercise, and increase of T lymphocytes in bronchoalveolar lavage with an inversion in the helper/suppressor ratio. In this paper, we discuss a 15-year experience with this pathological problem in Mexico, emphasizing the differences with this disorder in Caucasian populations. Generally, our patients display a chronic form of the disease, which evolves to fibrosis in about one-half of the patients. In this sense, the diagnostic, prognostic, and therapeutic focusing exhibit different elements, and thus the development of clinical and basic research is strongly required.

    Thirty patients with Burkitt's lymphoma sporadic type are presented. All of these cases fulfilled the histologic criteria of Burkitt's tumor. The age ranged from 2 to 12 years, with a median of 4 years. Fever and chills were the most common symptoms. The abdomen was the site of initial presentation in more than half of these cases. Close to one-third of the patients had involvement of the central nervous system. Fifty percent of the patients presented with lactic dehydrogenase elevation. Uric acid was elevated in close to one-fourth of these patients. The sonogram was the most useful technique in those instances of abdominal presentation. All patients were staged according to Ziegler criteria after an initial surgical diagnostic procedure was performed. None of the patients received radiotherapy to the primary tumor. All were submitted to a chemotherapy program for 12 months. Only 26 fitted the criteria of being evaluable. The duration of remission was from 1 to 144 months, with a median of 18.2 months. The actuarial survival was 84% at 3 years. Most of the responders corresponded to Stages A, B, and AR, while Stages C and D had a high mortality rate with elevated lactic dehydrogenase and uric acid levels.

    Objectives: The purpose of this study was to review the epidemiological aspects of displacement fractures of the acetabulum that had been treated surgically at the National Institute of Traumatology and Orthopedics (INTO). Methods: We retrospectively analyzed 126 acetabulum fractures that had been treated surgically at INTO between March 2006 and November 2008. The following factors were taken into account: age, sex, trauma mechanism, injury classification, time elapsed between trauma and surgery, affected side and associated bone injuries. Results: 76.8% were male; the mean age was 39.6 years. The trauma mechanism was traffic accidents in 59%; the time that elapsed between injury and surgery was on average 16.4 days; 55% of the cases were on the right side; 30% of the patients presented associated fractures. Conclusion: Most of the patients were male, in an economically active age group, and were victims of traffic accidents. Edge and/or posterior column fractures were the most frequent types. Associated injuries were common and most of the fractures operated in our service came to us late. PMID:27022597

    Leptodactylus macrosternum and L. vastus (family: Leptodactylidae) are commonly encountered in the "Caatinga" biome in northern Brazil. The body fat of L. vastus is used as a zootherapeutic for treating a number of human maladies. The aim of this work was to determine the chemical composition of the body fats of L. macrosternum and L. vastus and to evaluate their antimicrobial activities as well as the ecological implications of their use in traditional folk medicine. Oils were extracted from body fat located in the ventral region of L. macrosternum (OLM) and L. vastus (OLV) using hexane as a solvent. The fatty acids were identified by GC-MS. The antimicrobial activities of the oils, either alone or in combination with antibiotics and antifungal drugs, were tested on standard strains of microorganisms as well as on multiresistant strains of Escherichia coli and Staphylococcus. OLM contained 40% saturated and 60% unsaturated fatty acids, while OLV contained 58.33% saturated and 41.67% unsaturated fatty acids. Our results indicated that both OLM and OLV demonstrated relevant antimicrobial activities (with MIC 256  μ g/mL for both) against Pseudomonas aeruginosa and Candida krusei. However, no antimicrobial effects were observed when these oils were combined with antibiotics or antifungal drugs.

    The purpose of this study was to identify the rate of infections due to RSV and other viruses in children. In addition we have analyzed demographic data and clinical characteristics of the RSV-positive patients comparing with patients infected by other respiratory viruses. We also described the seasonality of the RSV occurrence in a hospital in São Paulo. Children below 5 years old admitted in Santa Casa de São Paulo Hospital between February 2005 and September 2006 due to acute respiratory infections (ARI) were included. A nasopharyngeal specimens were obtained with sterile No. 5 French feeding catheters as soon as possible (usually within 24 h). Specimens were kept refrigerated at 4 degrees C and transported to Adolfo Lutz Institute, where the indirect immunofluorescent assay was performed. Virus identified by these assay included RSV, Adenovirus, Influenza A and B virus and Parainfluenza 1, 2, and 3. Clinical data from each group was compared. Four hundred and fifty five cases were included in the study, with 30% positive for some type of virus. Viruses that were identified included Respiratory Syncytial Virus (73.03%), Influenza (8.42%), Parainfluenza (8.42%) and Adenovirus (3.37%). We divided the subjects in 3 groups: Group 1 RSV-Positive, Group 2 Other Positive Viruses and Group 3 Negative for Respiratory Virus. Mean age (months) was of 7.5 for RSV-positive children, 7.6 for other viruses, and 8 for negative for respiratory virus. The RSV-Positive Group was significantly younger than the Group Negative for Respiratory Virus (p<0.05). Signs of UAI were more present in the Positive RSV Group (p<0.05). General mortality was of 2.41%. There was a higher incidence of RSV between the months of March and August in the two years of the study. Our study indicates RSV as the most prevalent viral agent in children admitted due to (ARI), especially in infants below 3 months old. We have also found that infections due to RSV can occur in months others than the classic

    The experience of 52 children with Hodgkin's disease was reviewed. Compared with Hodgkin's disease in adults there was an increased incidence among boys. Mixed cellularity (MC) was the most common histologic type (60.5% in boys, and 64.4% in girls) as was also observed in adults (61.1% in men and 63.0% in women). The methods of therapy consisted of three main groups: extended-field radiotherapy (EFRT) + MOPP; involved-field radiotherapy (IVRT) + MOPP, 44.4% for IVRT + Monochemotherapy, and 80% for EFRT alone. The progressive improvement in results was associated with the change from IVRT to EFRT and the introduction of multiagent chemotherapy.

    The experience of 260 patients with endometrial carcinoma was reviewed. The influence of factors such as age, stage of disease, grade and degree of myometrial penetration on the survival was presented, showing that survival decreases in elderly patients, in patients with advanced stage of disease, when the tumor is undifferentiated, and when the tumor deeply penetrates the myometrium. The methods of therapy, fall into three main groups: surgery, radiotherapy, and combined therapy, the latter yielding the best 5-year survival rate, in all stages. The incidence of vaginal recurrences was low, probably due to the fact that 68.8% of the patients were treated by a combined therapeutic modality.

    Mesenteric cysts are rare abdominal tumors. About 60% of these cysts occurs before 5 years of age and can be located anywhere in the gastrointestinal tract, but are most often found in the small bowel mesentery. The clinical presentation depends on the location and size of the cyst and many cases are asymptomatic and are diagnosed incidentally. The most common symptoms are abdominal pain, bloating, abdominal mass, nausea, vomiting, constipation, diarrhea, weight loss, fever and peritonitis. Complications include torsion, infarction, volvulus formation, perforation, infection, anemia, intracystic hemorrhage, intestinal obstruction and obstructive uropathy. They are typically treated by simple excision, marsupialization or segmental bowel resection and have excellent long-term prognosis.

The illness, as a sign of family imbalance within the humanistic concept, acquires an even if the treatment is given to the marital couple, the adolescent or the child. Family therapy helps in marital disagreements, behavior problems, anorexia, reactive depression, drug addictions, alcoholism and many other problems. The ISSSTE population has a stable location and is more or less homogeneous; in it family therapy is stimulating and possible; even though the institution imposes certain limitations to family therapy, the enthusiasm for this therapeutic method prevails.

    Stress, is considered to be a bodily response to both internal and environmental stimuli, is a live and unavoidable energy. It is important and necessary to learn to use it beneficially. In order to determine the utility of the educational program. "The use use and control of stress", a quasi-experimental study was conducted in 1993, in which 39 voluntary Zone I General Hospital (IMSS Tlaxcala State Delegation) workers were selected, based on stress levels over 3 points as found in an institutional validated to measure the stress level. Five groups were set up, and eight weekly educative interventions, composed of cognitive contents including stress, relaxation techniques, and techniques for living of 90 minutes each were attended by the members of these groups, utilizing groups dynamics. The results were analyzed in simple absolute and relative frequencies, as well as by Student's t tests. They show a reduction stress levels in 94.8% of the participants, which represents a 69.1% general gain, with p = < 0.005. The conclusion is that learning related with the use and control of stress is an alternative to improve the mental health of the individual and as concerns the work environment, to modify attitude of the IMSS worker.

    The diagnosis and treatment of thyroid disease has significantly changed with time. With the aim of analysing changes in thyroid surgery in our institution, a representative sample of patients from the first three years in four decades (1960-1992) were comparatively analysed. In the sixties, the diagnosis of thyroid cancer was made during surgery; by contrast, this diagnosis was correctly done by fine needle aspiration (FNA) in most patients of the last decade. Thyroid lobectomy, infrequently used in the treatment of differentiated thyroid carcinoma in earlier times, has now been abandoned and currently most patients undergo total or near-total thyroidectomy. Complications such as hypoparathyroidism and recurrent laryngeal nerve paralysis have importantly decreased with time and were not seen in the last decade. A trend toward an earlier diagnosis of thyroid carcinoma was also observed. In summary, the number of thyroidectomies for benign diseases has been importantly reduced by the use of FNA with the proportional increment of surgery for malignant disease.

    The purpose of this retrospective study was to study the incidence of idiopathic and secondary forms of membranous nephropathy in our institution, its clinical course and progression to chronic renal failure, and the risk factors associated with it. Two hundred fourteen (16%) of the 1,287 renal biopsies obtained between 1962 and 1988 were primary glomerular diseases and 28 of this 214 (13%) were idiopathic membranous nephropathy. On the other hand 59 of 1,287 biopsies were membranous nephropathy of whom 28 were idiopathic, 27 secondary to systemic lupus erythematosus, 2 due to drugs, one associated with rheumatoid arthritis, and one more with breast cancer. The clinical picture was: nephrotic syndrome in 84%, hypertension in 15%, non-nephrotic proteinuria in 14%, chronic renal failure in 8.4%, and renal vein thrombosis in 6.3%. In the idiopathic group 75% of the patients were male while in the lupus group 85% were female. For the analysis of progression to chronic renal failure we excluded 5 patients with renal failure when the biopsy was taken, 2 because the nephropathy was due to drugs, one associated with breast cancer, and nine were within the first year of follow-up. Thus, for this analysis the group consisted of 22 patients with idiopathic form and 20 with systemic lupus erythematosus. The idiopathic and lupus groups were similar except for a lower serum albumin in the former. The progression to renal failure was seen in 9 patients: six in the idiopathic group and the other 3 in the lupus group; this difference was not significant.(ABSTRACT TRUNCATED AT 250 WORDS)

    The ingestion of foreign bodies (EC) is a problem commonly seen by pediatricians and emergency physicians. The intake is almost always accidental and most common objects are coins, pieces of toys, jewelry or batteries. The button batteries are the most common, in which case is important early diagnosis and removal. The cylindrical battery ingestion is very rare, are typically alkaline manganese or nickel-cadmium (rechargeable) and when ingested they can cause toxic and corrosive damage. Such damage may occur as a result of the effect of acid gastric contents sustained over a period of days or weeks. We report the case of a patient who accidentally ingested a cylindrical battery, which was removed from the stomach endoscopically without complications.

Métodos: se estudiaron los pacientes que ingresaron al Servicio de Urgencias con diagnóstico de choque séptico y a quienes se les determinó lactato sérico al ingreso durante el periodo que abarca de enero a diciembre de 2013; se trató de un estudio de casos y controles. El valor de corte del lactato sérico asociado a mortalidad se realizó con las curvas ROC (del inglés receiver operating characteristic: característica operativa del receptor). Resultados: se estudiaron 67 pacientes del mes de enero al mes de diciembre del 2013. Sobrevivieron 56 (casos) y murieron 11 (controles). No hubo asociación con el género, la edad y las comorbilidades. El valor de corte para mortalidad del lactato sérico fue de 4.9 mmol/L. Fallecieron 10 de 40 pacientes con niveles de lactato > 4.9 mmol/L en comparación con solo uno de 27, con < 4.9 mmol/L, (p = 0.04) y razón de momios de 8.7. La mortalidad con valores de lactato > 4.9 mmol/L tuvo una sensibilidad de 90.9 % y una especificidad de 46.4 %. Conclusiones: los niveles de lactato sérico mayores a 4 mmol/L están asociados a un mayor riesgo de mortalidad en pacientes con choque séptico.

    Up to now, the best treatment for patients with acute myelogenous leukemia (AML) is the induction of bone marrow hypoplasia by ablative combined chemotherapy; the prototype of these schedules is the so-called 7 + 3 (seven days of continuous infusion of cytarabine and three days of one-hour infusion of any anthracycline); these schedules require the support of both platelet transfusions and antibiotics. Other non-ablative schedules have also been tried in the treatment of such patients. Here we analyze the results of the treatment of 76 adult patients with AML; 43 were treated with the classical 7 + 3 schedule, whereas 33 were treated with a combination of chemotherapy used in non-ablative doses (TADOP: thioguanine, arabinosyl-citosine, doxorrubicin, vincristine and prednisone). The results were as follows, respectively, for 7 + 3 and TADOP: complete remission (CR) was achieved in 60 and 48% of patients (p NS); the number of cycles to achieve CR had a median of 1 and 5 months (p less than 0.001); the median duration of the CR was 21 and 10 months (p less than 0.05); fatal myelotoxicity was 30 and 42% (p NS), one-year disease free survival (DFS) was 45 and 46% (p NS) and three-year survival was 22% and 15% (p NS). Additionally, patients treated with 7 + 3 were divided into two groups according to the type of platelet transfusion support; those supported with apheresis equipment and those with centrifugation-derived platelets.(ABSTRACT TRUNCATED AT 250 WORDS)

    Background Natural polyploidy has played an important role during the speciation and evolution of vertebrates, including anurans, with more than 55 described cases. The species of the Phyllomedusa burmeisteri group are mostly characterized by having 26 chromosomes, but a karyotype with 52 chromosomes was described in P. tetraploidea. This species was found in sintopy with P. distincta in two localities of São Paulo State (Brazil), where triploid animals also occur, as consequence of natural hybridisation. We analyse the chromosomes of P. distincta, P. tetraploidea, and their triploid hybrids, to enlighten the origin of polyploidy and to obtain some evidence on diploidisation of tetraploid karyotype. Results Phyllomedusa distincta was 2n = 2x = 26, whereas P. tetraploidea was 2n = 4x = 52, and the hybrid individuals was 2n = 3x = 39. In meiotic phases, bivalents were observed in the diploid males, whereas both bivalents and tetravalents were observed in the tetraploid males. Univalents, bivalents or trivalents; metaphase II cells carrying variable number of chromosomes; and spermatids were detected in the testis preparations of the triploid males, indicating that the triploids were not completely sterile. In natural and experimental conditions, the triploids cross with the parental species, producing abnormal egg clutches and tadpoles with malformations. The embryos and tadpoles exhibited intraindividual karyotype variability and all of the metaphases contained abnormal constitutions. Multiple NORs, detected by Ag-impregnation and FISH with an rDNA probe, were observed on chromosome 1 in the three karyotypic forms; and, additionally, on chromosome 9 in the diploids, mostly on chromosome 8 in the tetraploids, and on both chromosome 8 and 9 in the triploids. Nevertheless, NOR-bearing chromosome 9 was detected in the tetraploids, and chromosome 9 carried active or inactive NORs in the triploids. C-banding, base-specific fluorochrome stainings with CMA3 and DAPI, FISH with a telomeric probe, and BrdU incorporation in DNA showed nearly equivalent patterns in the karyotypes of P. distincta, P. tetraploidea, and the triploid hybrids. Conclusions All the used cytogenetic techniques have provided strong evidence that the process of diploidisation, an essential step for stabilising the selective advantages produced by polyploidisation, is under way in distinct quartets of the tetraploid karyotype.

    The use of bortezomib as a treatment modality of AHR improved and stabilized graft function (clinical response) in the majority of patients. Its use in single dose, even combined with rituximab, does not seem to be useful to obtain a sustained clinical response, or to reduce HLAabs level. The use of 4 doses of bortezomib in days 1, 4, 7, and 10 (1.3 mg/m2 BSA each) plus plasmapheresis produced both a good clinical response and a reduction in DSA. Moving forward, it will be necessary to define the long-term effectiveness of bortezomib and whether rituximab administration is indispensable to achieve this goal. Until now, it is evident that many patients needed retreatment and they were well tolerated.

    The goal of this presentation is the description of the epidemiologic evolution and changes in natural history of the human immunodeficiency virus infection (HIV) epidemic itself and its relation with the acquired immunodeficiency syndrome-related lymphoma (ARL). We have started with the description of the world's state of the HIV epidemic, its features since the first case report in the United States of America in 1981, through the peak of new diagnoses in 1993 until the event that changed the natural history of the disease: the era of the widespread use of the highly active antiretroviral therapy (HAART), introduced in 1995 in the world and in 1997 in our country. The widespread introduction of HAART led to dramatic reductions in AIDS related mortality and morbidity throughout the developed world with a marked fall in the incidence of the major opportunistic infections in AIDS. We describe the main risk factors for the development of ARL, and the prognostic factors for survival and response to treatment. There is no clear definition in the literature of the roll that has played the use of HAART in relation to survival and response to treatment in ARL, but there is evidence that the basal count of CD4 cells has increased with HAART, leading to a better survival and response in ARL. The debate regarding this issue is surely affected by factors such as degree of antiretroviral treatment compliance, antiretroviral therapy resistance and chemotherapy heterogeneity. Finally we present the preliminary results of the analysis of our experience in ARL from 1986 to 2003.

    Pioneering scientific information in underdeveloped areas poses several problems, such as (1) lack of understanding on the part of key functionaries as to the why, what, and when of information services; (2) lack of trained personnel to assume the responsibility for such services; (3) lack of economic resources; and (4) lack of information pertaining to available bibliographical sources in the particular area or region. The Bibliographic and Documentation Service of the Institute of Nutrition of Central America and Panama (INCAP) provides, in addition to the customary services, technical assistance for the organization or reorganization of biomedical libraries and makes INCAP library materials available to member countries, either by loan or photocopy. Although the program was designed for the member countries, INCAP tries to make its services available to other Latin American nations, Africa, and Asia, where similar nutritional problems are being studied.

  20. Overland Flow Generation and Soil Hydraulic Properties in Two Catchments in Central Panama

    NASA Astrophysics Data System (ADS)

    Godsey, S.; Elsenbeer, H.; Stallard, R.

    2003-12-01

    Land management decisions in the Panama Canal watershed directly impact the hydrological functioning of the canal itself. Knowledge of the hydrological conditions in the forested portions of the watershed provides a baseline comparison for future land use changes. We chose to work on two streams on Barro Colorado Island that are representative of large regions of the watershed. These two streams respond differently to the same storm events: Conrad Trail Stream exhibits a fairly subdued and delayed response and Lutz Creek stream is flashier. In order to understand these differences, we investigated the soil saturated hydraulic conductivity (Ks) of the two catchments and studied the frequency of overland flow generation. The Ks measurements in dominant geologies in Lutz Creek as well as in Conrad Trail Stream are great enough at shallow depths (median Ks = 29.7, 65.6 and 38.3 mm/hr) that Hortonian overland flow is rare, but a marked decrease in Ks in Lutz Creek catchment at 30 cm (to 1.4 and 5.8 mm/hr) indicates that a perched water table leading to saturated overland flow is the likely runoff mechanism in Lutz Creek. In Conrad, Ks does not decrease as markedly with soil depth, and a perched water table would form at about 60 cm below the surface (median Ks = 0.7 mm/hr). Therefore, more water is able to infiltrate into the soil in Conrad Trail Stream and saturated overland flow is less common. Overland flow was generated much more frequently in Lutz Creek than in Conrad Trail Stream, with lower thresholds of storm magnitude, duration, antecedent wetness and intensity required to generate overland flow. We also quantified the importance of microtopographic features such as concentrated flow lines and the results have implications for experimental design at other field sites. The Lutz Creek and Conrad Trail stream information will provide a useful baseline for land management decisions.

    The species diversity and seasonal abundance of biting midges of the genus Culicoides (Diptera: Ceratopogonidae) were studied in northwestern Argentina during the period 2003-2005. A total of 5437 Culicoides specimens were collected using CDC light traps in three areas of the mountainous rainforest area. The most common species were Culicoides paraensis (Goeldi) and C. insignis Lutz, Culicoides lahillei (Iches), C. venezuelensis Ortiz & Mirsa, C. debilipalpis Lutz and C. crescentis Wirth & Blanton were also collected. Culicoides paraensis was abundant during the summer, and C. insignis and C. lahillei during late summer and early fall. Accumulated rainfall was the climatic variable most related to fluctuation in abundance of C. paraensis.

    2009-12-01

    The normal phase diffusion problem in magnetic resonance imaging (MRI) is treated by means of the Langevin equation for the phase variable using only the properties of the characteristic function of Gaussian random variables. The calculation may be simply extended to anomalous diffusion using a fractional generalization of the Langevin equation proposed by Lutz [E. Lutz, Phys. Rev. E 64, 051106 (2001)] pertaining to the fractional Brownian motion of a free particle coupled to a fractal heat bath. The results compare favorably with diffusion-weighted experiments acquired in human neuronal tissue using a 3 T MRI scanner.

On each campaign 60 samples were collected, using 30 x 30 cm wooden quadrats, distributed at four sites: Taquaral, Véu da Noiva, Três Picos and Brejo da Lapa. The winter and spring campaigns included two additional sampling sites: Alsene and Agulhas Negras. A total of 3578 larvae and 292 pupae were sampled, representative of six species: Simulium clavibranchium Lutz, S. subnigrum Lutz, S. rappae Py-Daniel, S. incrustatum Lutz, S. stellatum Gil-Azevedo, Figueiró & Maia-Herzog and Lutzsimulium pernigrum Lutz 1910. The highest larvae abundance and diversity were reported at the intermediate altitude site, Brejo da Lapa. Principal Components Analysis (PCA) revealed that L. pernigrum, S. stellatum and S. incrustatum were associated with the smaller breeding sites, the first two species being associated with sunny sites, while S. incrustatum occurred in sites with little sunlight.

    Balantidium coli is a protozoon that can cause dysentery in humans, pigs and nonhuman primates, with zoonotic potential. In the literature, there is still little information on the effectiveness of different laboratory techniques for diagnosing this disease. This study compared and evaluated the performance of the Lutz, modified Ritchie, Faust, modified Sheather and direct examination techniques for detecting cysts of this protozoon. Between 2012 and 2014, 1905 fecal samples were collected from captive animals in the state of Rio de Janeiro. Of these, 790 were obtained from the rectum of pigs and 1115 from enclosures occupied by nonhuman primates. B. coli cysts were most evident through direct examination (22.4% of the samples) and the Lutz technique (21%). Fair agreement (Kappa = 0.41; p < 0.05) was observed only between direct examination and Lutz. The flotation techniques (Faust and modified Sheather) did not show good recovery of cysts. A statistically significant difference (p < 0.05) in the frequency of cysts between pigs and nonhuman primates could only be observed through direct examination and the Lutz technique. The most efficient method for diagnosing this parasitosis was seen to an association between direct examination and the spontaneous sedimentation technique.

    Lutzomyia longipalpis (Lutz & Neiva) is the primary vector of visceral leishmaniasis in Venezuela. An analysis of alleles at seven enzyme-encoding loci among four populations from different geographic and epidemiological regions revealed strong genetic substructuring. Isozyme analysis indicated that L. longipalpis in Venezuela is a complex of at least two subspecies. Possible differences in population size during their evolutionary histories, varying colonization histories and geological events may explain discrepancies in the patterns of variation observed at genetic markers between these four populations.

    This is a theoretical reflection that aims to encourage readers to rethink the role of permanent education of health and nursing subjects/workers in the perspective of individual and collective development through transformative praxis. We tried to make a thoughtful articulation about principles of transformative praxis presented by the philosopher Adolfo Sánchez Vázquez with the precepts of permanent education in health and nursing work. This articulation presents an educational concept in favor of the subject-worker's awareness about the distinct contributions of personal, social, relational and institutional arrangements that may result from different ways of perceiving and practicing permanent education in health and nursing work.

  12. Cohesion of wet grains at high liquid content

    2015-11-01

    Adding liquid to a granular medium highly increases its cohesion, due to the creation of capillary bridges between grains. From the paste obtained by mixing a large amount of water to spherical glass beads (~ 100 μm), we cast a compact beam. We study its rupture under its own weight, then deduce the cohesive strength, which increases with water content. This behavior diverges from what is expected from individual capillary bridges, suggesting a role of the liquid repartition in the granular medium. Curently at the Universidad Adolfo Ibañez (Chile).

    2014-06-01

    Purpose: To automate routine imaging QA procedures so that complying with TG 142 and TG 179 can be efficient and reliable. Methods: Two QA tests for a True Beam Linac were automatized. A Winston Lutz test as described by Lutz et al{sup 1} using the Winston Lutz test kit from BrainLab, Germany and a CBCT Image Quality test as described in TG 179 using the EMMA phantom, Siemens Medical Physics, Germany were performed in our True Beam. For each QA procedure tested, a 3 step paradigm was used. First, the data was automatically acquired using True Beam Developer Mode and XML scripting. Second, the data acquired in the first step was automatically processed using in-home grown Matlab GUIs. Third, Machine Learning algorithms were used to automatically classify the processed data and reports generated. Results: The Winston Luzt test could be performed by an experienced medical physicist in 29.0 ± 8.0 min. The same test, if automated using our paradigm, could be performed in 3.0 ± 0.1 min. In the same lieu, time could be substantially saved for image quality tests. In this case, the amount of time saved will depend on the phantoms used and the initial localization method. Additionally, machine learning algorithms could automatically identify the roots of the problems if any and possibly help reduce machine down time. Conclusion: Modern linear accelerators are equipped with advanced 2D and 3D imaging that are used for patient alignment substantially improving IGRT protocols. However, this extra complexity exponentially increases the number of QA tests needed. Using the new paradigm described above, not only bare minimum but best practice QA programs could be implemented with the same manpower. This work is supported by Varian, Palo Alto, CA.

  5. Overland flow generation in two lithologically distinct rainforest catchments

    Streams on uniformly rainforest-covered, but lithologically very diverse Barro Colorado Island in central Panama?? show remarkable differences in their runoff response to rainfall. This lithological diversity is reflected in equally diverse soilscapes, and our objective was to test the hypothesis that contrasting runoff responses derive from soilscape features that control the generation of overland flow. We determined the soil saturated hydraulic conductivity (Ks) of two neighboring, but hydrologically contrasting catchments (Lutz Creek with a flashy and Conrad Trail with a delayed response to rainfall), and quantified the spatial and temporal frequency of overland flow occurrence. The median Ks values at a depth of 12.5 cm are large enough to rule out Hortonian overland flow, but a marked decrease in K s in Lutz Creek catchment at 30 cm suggests the formation of a perched water table and the generation saturation overland flow; the decrease in Ks in the Conrad Trail catchment is more gradual, and a perched water table is expected to form only at depths below 50 cm. In Lutz Creek, overland flow was generated frequently in time and space and regardless of topographic position, including near the interfluve, with very low thresholds of storm magnitude, duration, intensity and antecedent wetness, whereas in Conrad Trail, overland flow was generated much less frequently and then only locally. We conclude that soilscape features and microtopography are important controls of overland flow generation in these catchments. Our results contribute to the growing evidence that overland flow and forests are not a priori a contradiction in terms. ?? 2004 Elsevier B.V. All rights reserved.

    2011-01-15

    Purpose: To design a fast Winston Lutz (fWL) algorithm for accurate analysis of radiation isocenter from images without edge detection or center of mass calculations. Methods: An algorithm has been developed to implement the Winston Lutz test for mechanical/radiation isocenter agreement using an electronic portal imaging device (EPID). The algorithm detects the position of the radiation shadow of a tungsten ball within a stereotactic cone. The fWL algorithm employs a double convolution to independently find the position of the sphere and cone centers. Subpixel estimation is used to achieve high accuracy. Results of the algorithm were compared to (1) a human observer with template guidance and (2) an edge detection/center of mass (edCOM) algorithm. Testing was performed with high resolution (0.05mm/px, film) and low resolution (0.78mm/px, EPID) image sets. Results: Sphere and cone center relative positions were calculated with the fWL algorithm for high resolution test images with an accuracy of 0.002{+-}0.061 mm compared to 0.042{+-}0.294 mm for the human observer, and 0.003{+-}0.038 mm for the edCOM algorithm. The fWL algorithm required 0.01 s per image compared to 5 s for the edCOM algorithm and 20 s for the human observer. For lower resolution images the fWL algorithm localized the centers with an accuracy of 0.083{+-}0.12 mm compared to 0.03{+-}0.5514 mm for the edCOM algorithm. Conclusions: A fast (subsecond) subpixel algorithm has been developed that can accurately determine the center locations of the ball and cone in Winston Lutz test images without edge detection or COM calculations.

  8. Use of charts for flow discharge calculations

    1941-01-01

    Various problems in connection with engine design involve flow-discharge calculations which are rendered difficult both on account of the large number of external variables that enter into the computation - i.e., changes in discharge area during the process, change in volume of the cylinder, pressure, etc., and changes in the thermal constants themselves of the flow medium. A fairly accurate solution that does not involve an excessive amount of labor can be obtained only through the extensive use of i-s tables. In the present report, a solution is offered in the form of a different method making use of the I-S table of Lutz and Wolf.

    Hipparcos parallaxes were used to derive absolute visual magnitudes of G, K, and M stars with Ca II emission line widths previously measured by O.C. Wilson. A linear relationship similar to the one derived originally by Wilson & Bappu and improved by Lutz & Kelker was found from Mv=+7 to -2. For stars brighter than Mv=-2 a substantial number of stars show Ca II emission lines that are broader than expected from the linear fit. Most of those stars are bright giants and supergiants of type G. (3 data files).

  20. Identifying storm flow pathways in a rainforest catchment using hydrological and geochemical modelling

    USGS Publications Warehouse

    Kinner, D.A.; Stallard, R.F.

    2004-01-01

    The hydrological model TOPMODEL is used to assess the water balance and describe flow paths for the 9??73 ha Lutz Creek Catchment in Central Panama. Monte Carlo results are evaluated based on their fit to the observed hydrograph, catchment-averaged soil moisture and stream chemistry. TOPMODEL, with a direct-flow mechanism that is intended to route water through rapid shallow-soil flow, matched observed chemistry and discharge better than the basic version of TOPMODEL and provided a reasonable fit to observed soil moisture and wet-season discharge at both 15-min and daily time-steps. The improvement of simulations with the implementation of a direct-flow component indicates that a storm flow path not represented in the original version of TOPMODEL plays a primary role in the response of Lutz Creek Catchment. This flow path may be consistent with the active and abundant pipeflow that is observed or delayed saturation overland flow. The 'best-accepted' simulations from 1991 to 1997 indicate that around 41% of precipitation becomes direct flow and around 10% is saturation overland flow. Other field observations are needed to constrain evaporative and groundwater losses in the model and to characterize chemical end-members posited in this paper.

  1. ON PULSAR DISTANCE MEASUREMENTS AND THEIR UNCERTAINTIES

    Accurate distances to pulsars can be used for a variety of studies of the Galaxy and its electron content. However, most distance measures to pulsars have been derived from the absorption (or lack thereof) of pulsar emission by Galactic H I gas, which typically implies that only upper or lower limits on the pulsar distance are available. We present a critical analysis of all measured H I distance limits to pulsars and other neutron stars, and translate these limits into actual distance estimates through a likelihood analysis that simultaneously corrects for statistical biases. We also apply this analysis to parallax measurements of pulsars in order to obtain accurate distance estimates and find that the parallax and H I distance measurements are biased in different ways, because of differences in the sampled populations. Parallax measurements typically underestimate a pulsar's distance because of the limited distance to which this technique works and the consequential strong effect of the Galactic pulsar distribution (i.e., the original Lutz-Kelker bias), in H I distance limits, however, the luminosity bias dominates the Lutz-Kelker effect, leading to overestimated distances because the bright pulsars on which this technique is applicable are more likely to be nearby given their brightness.

    Purpose: The Mevion proton therapy machine is the first to feature a gantry mounted sychro-cyclotron. In addition, the system utilizes a 6D motion couch and kV imaging for precise proton therapy. To quantify coincidence between these systems, isocentricity tests were performed based on kV imaging alignment using radiochromic film. Methods: The 100 ton gantry and 6D robotic couch can rotate 190° around isocenter to provide necessary beam angles for treatment. The kV sources and detector panels are deployed as needed to acquire orthogonal portals. Gantry and couch mechanical isocenter were tested using star-shots and radiochromic-film (RCF). Using kV imaging, the star-shot phantom was aligned to an embedded fiducial and the isocenter was marked on RCF with a pinprick. The couch and gantry stars were performed by irradiating films at every 45° and 30°, respectively. A proton beam with a range and modulation-width of 18 cm was used. A Winston-Lutz test was also performed at the same gantry and couch rotations using a custom jig holding RCF and a tungsten ball placed at isocenter. A 2 cm diameter circular aperture was used for the irradiation. Results: The couch star-shot indicated a minimum tangent circle of 0.6 mm, with a 0.9 mm offset from the manually marked isocenter. The gantry star-shot showed a 0.6 mm minimum tangent circle with a 0.5 mm offset from the pinprick. The Winston Lutz test performed for gantry rotation showed a maximum deviation from center of 0.5 mm. Conclusion: Based on star-shots and Winston-Lutz tests, the proton gantry and 6D couch isocentricity are within 1 mm. In this study, we have shown that the methods commonly utilized for Linac characterization can be applied to proton therapy. This revolutionary proton therapy system possesses excellent agreement between the mechanical and radiation isocenter, providing highly precise treatment.

    2014-06-01

    Purpose: To quantify the sub millimeter overall accuracy of EDGETM, the dedicated linac based SRS/SABR treatment platform from Varian, using a novel End-to-End (E2E) test phantom. Methods: The new E2E test phantom developed by Varian consists of a cube with an outer dimension of 15x15x15 cm3. The phantom is equipped with an exchangable inner cube (7×7×7 cm3) to hold radiochromic films or a tungsten ball (diameter = 5 mm) for Winston-Lutz tests. 16 ceramic balls (diameter = 5 mm) are embedded in the outer cube. Three embedded Calypso transponders allow for Calypso based monitoring. The outer surface of the phantom is tracked using the Optical Surface Monitoring System (OSMS). The phantom is positioned using kV, MV and CBCT images. A simCT of the phantom was acquired and SRS/SABR plans were treated using the new phantom on the first clinical installed EDGETM. As a first step a series of EPID based Winston-Lutz tests have been performed. As a second step the calculated dose distribution applied to the phantom was verified with radiochromic films in orthogonal planes. The measured dose distribution is compared with the calculated (Eclipse) one based on the known isocenter on both dose distributions. The geometrical shift needed to match both dose distributions is the overall accuracy and is determined using dose profiles, isodose lines or gamma pass rates (3%, 1 mm). Results: Winston-Lutz tests using the central tungsten BB demonstrated a targeting accuracy of 0.44±0.18mm for jaw (2cm × 2cm) defined 0.39±0.19mm for MLC (2cm × 2cm) defined and 0.37±0.15mm for cone (12.5 mm) defined fields. A treated patient plan (spinal metastases lesion with integrated boost) showed a dosimetric dose localization accuracy of 0.6mm. Conclusion: Geometric and dosimetric E2E tests on EDGETM, show sub-millimeter E2E targeting and dose localisation accuracy.

    2015-06-15

    Purpose To implement and evaluate an image-based Winston-Lutz (WL) test to measure the displacement between ExacTrac imaging origin and radiation isocenter on a Novalis Tx system using RIT V6.2 software analysis tools. Displacement between imaging and radiation isocenters was tracked over time. The method was applied for cone-based and MLC-based WL tests. Methods The Brainlab Winston-Lutz phantom was aligned to room lasers. The ExacTrac imaging system was then used to detect the Winston- Lutz phantom and obtain the displacement between the center of the phantom and the imaging origin. EPID images of the phantom were obtained at various gantry and couch angles and analyzed with RIT calculating the phantom center to radiation isocenter displacement. The RIT and Exactrac displacements were combined to calculate the displacement between imaging origin and radiation isocenter. Results were tracked over time. Results Mean displacements between ExacTrac origin and radiation isocenter were: VRT: −0.1mm ± 0.3mm, LNG: 0.5mm ± 0.2mm, LAT: 0.2mm ± 0.2mm (vector magnitude of 0.7 ± 0.2mm). Radiation isocenter was characterized by the mean of the standard deviations of the WL phantom displacements: σVRT: 0.2mm, σLNG: 0.4mm, σLAT: 0.6mm. The linac couch base was serviced to reduce couch walkout. This reduced σLAT to 0.2mm. These measurements established a new baseline of radiation isocenter-imaging origin coincidence. Conclusion The image-based WL test has ensured submillimeter localization accuracy using the ExacTrac imaging system. Standard deviations of ExacTrac-radiation isocenter displacements indicate that average agreement within 0.3mm is possible in each axis. This WL test is a departure from the tradiational WL in that imaging origin/radiation isocenter agreement is the end goal not lasers/radiation isocenter.

    Purpose: To test the accuracy and reproducibility of both translational and rotational movements for a couch with six degrees of freedom (6DoF) using a novel phantom design Methods: An end-to-end test was carried out using two different phantoms. A 6 cm3 cube with a central fiducial BB (WL-QA Sun Nuclear) and a custom fabricated rectangular prism (31 cm x 8 cm x 8 cm), placed on a baseplate with known angular offsets for pitch, roll and yaw with a central fiducial BB and unique surface structures for registration purposes, were used. The end-to-end test included an initial CT simulation for a reference study, setup to an offset mark on each phantom, registration of the reference CT to the acquired cone-beam CT, and final Winston-Lutz delivery at four cardinal gantry angles. Results for both translational and rotational movements were recorded and compared for both phantoms. Results: Translational and rotational measurements were performed with a PerfectPitch (Varian) couch for 10 trials for both phantoms. Distinct translational shifts were [−5.372±0.384mm, −10.183±0.137mm, 14.028±0.155mm] for the cube and [7.520±0.159mm, −9.117±0.101mm, 16.273±0.115mm] for the prototype phantom for lateral, longitudinal, and vertical shifts, respectively. Distinct rotational adjustments were [1.121±0.102o, −1.067±0.235o, −2.662±0.380o] for the cube and [2.534±0.059o, 1.994±0.025o, 2.094±0.076o] for the prototype for pitch, roll, and yaw, respectively. Winston-Lutz test results performed after 6DoF couch correction from each cardinal gantry angle ranged from 0.26–0.72mm for the cube and 0.55–0.86mm for the prototype. Conclusion: The prototype phantom is more precise for both translational and rotational adjustments compared to a commercial phantom. The design of the prototype phantom allows for a more discernible visual confirmation of correct translational and rotational adjustments with the prototype phantom. Winston-Lutz results are more accurate for the

    The phlebotomine sand flies Lutzomyia (Nyssomyia) intermedia (Lutz & Neiva) and Lutzomyia (Nyssomyia) whitmani (Coutinho & Antunes) are important vectors of Leishmania (Vianna) braziliensis, the etiological agent of American cutaneous leishmaniasis. In some areas, both species occur in sympatry, and their relative roles as vectors in these areas are not clear. We studied the nocturnal activity and biting rhythms of both species in Posse, a locality in Rio de Janeiro State, Brazil. Our results show differences between the activity patterns of Lu. intermedia and Lu. whitmani that might be epidemiologically important. Although the activity profiles vary between seasons and microhabitats (peridomestic versus forest), the two species show marked differences in their tendencies to bite humans in the early morning (0400-0600 hours), with Lu. whitmani showing higher feeding rates than Lu. intermedia.

    The complete primary structures of toxin II-14 from the Mexican scorpion Centruroides noxius Hoffmann and toxin gamma from the Brazilian scorpion Tityus serrulatus Lutz and Mello have been determined. Cleavage of toxin gamma after Met-6 with CNBr produced the 55-residue peptide 7-61, which maintained the four disulphide bonds but was not toxic to mice at a dose 3 times the lethal dose of native toxin gamma. Pairwise comparison by metric analysis of segment 1-50 of toxin gamma and the corresponding segments from two other South American scorpion toxins, five North American scorpion toxins, nine North African scorpion toxins and one Central Asian scorpion toxin showed that the three Brazilian toxins are intermediate between the North American and North African toxins. This result is consistent with the hypothesis that the South American and African continents were joined by a land connection in the distant past. Images Fig. 1. PMID:4052021

    Bertha Lutz was one of the women of her generation who enjoyed indisputable political and scientific authority. She wrote much and even more was written about her, especially during her day. The newspaper chronicles by Lima Barreto, countless letters, scientific papers, and unpublished texts by Bertha herself that are surveyed in this article indicate how much her feminism--inseparable from other dimensions of her life--fostered her professional career. Her feminism earned her a carefully constructed renown and visibility that interlocked with her professional performance. Science lent her social prestige and guaranteed legitimacy for her causes. During a period when the scientific community itself was engaged in publicizing its own activities, Bertha's feminist prominence in the media helped her make a name in the sciences.

    2015-01-01

    Since the description of Lutzomyia longipalpis by Lutz and Neiva more than 100 years ago, much has been written in the scientific literature about this phlebotomine species. Soares and Turco (2003) and Lainson and Rangel (2005) have written extensive reviews focused on vector-host-parasite interactions and American visceral leishmaniasis ecology. However, during the last two decades, the success of Lu. longipalpis in colonising urban environments and its simultaneous geographical spreading have led to new theoretical and operational questions. Therefore, this review updates the general information about this species and notes the more challenging topics regarding the new scenario of urbanisation-spreading and its control in America. Here, we summarise the literature on these issues and the remaining unsolved questions, which pose recommendations for operational research. PMID:26517497

    The goal of this survey was to analyze the spatio-temporal distribution patterns of Culicoides Latreille species (Diptera: Ceratopogonidae) and their relationship with environmental variables in Salta, northwestern Argentina. Culicoides were collected monthly from January 2003 through December 2005. The influence of the climatic variables on population abundance was analyzed with a multilevel Poisson regression. A total of 918 specimens belonging to five species were collected. The most abundant species was Culicoides paraensis Goeldi (65.5%), followed by Culicoides lahillei Iches (14.6%) and Culicoides debilipalpis Lutz (7.6%). The highest seasonal abundance for C. paraensis, C. debilipalpis and C. lahillei occurred during the spring and summer. A Poisson regression analysis showed that the mean maximum and minimum temperature and the mean maximum and minimum humidity were the variables with the greatest influence on the population abundance of Culicoides species.

    The Steamboat Springs geothermal system provides the most dramatic example of subhorizontal thermal-fluid aquifers in crystalline rock in the Basin and Range, but this is by no means an isolated case. Similar but more diffuse subhorizontal permeability has been reported at Roosevelt Hot Springs and Cove-Fort Sulphurdale, Utah; and a km-scale gravity-slide block channels injectate at Dixie Valley, Nevada. During the course of this phase of the project 2543 reports including text, figures and large format enclosures, 1428 maps, and 698 well logs were scanned. The information is stored in a Microsoft Access Database on the Geothermal Server. Detailed geologic cross sections of the Desert Peak geothermal field were developed to identify the structural controls on the geothermal system and locate possible fluid flow paths. The results of this work were published by Lutz and others (2009, Appendix 1) in the Stanford Reservoir Engineering Conference Proceedings.

    In this study, we examined global treatment outcomes during 16 months of intensive, psychodynamic treatment for 77 inpatients suffering from treatment-refractory disorders. Hypotheses based on the phase model of treatment change (Howard, Lueger, Maling, & Martinovich, 1993; Howard, Moras, Brill, Martinovich, & Lutz, 1996) were supported in the study results. Diagnostic and Statistical Manual of Mental Disorders (4th ed.; American Psychiatric Association, 1994) Axis V scales assessing behavioral functioning demonstrated large and medium effect size change, whereas stable, enduring personality functioning assessed by psychoanalytic Rorschach scales and the Social Cognition and Object Relations Scale (Westen, 1995) for the Thematic Apperception Test (Murray, 1943) demonstrated small and medium effect size change. We also report assessment of reliable change index and clinical significance. The ecological validity of Rorschach measures is supported by significant validity coefficients (in the hypothesized directions) between implicit measures of personality functioning and behavioral ratings.

    The precision of a medical LINear ACcelerator (LINAC) gantry rotation angle is crucial for the radiation therapy process, especially in stereotactic radio surgery, given the expected precision of the treatment and in Image Guided Radiation Therapy (IGRT) where the mechanical stability is disturbed due to the additional weight of the kV x-ray tube and detector. We present in this paper an extension of the Winston and Lutz test initially dedicated to control the size and the position of the isocenter of the LINAC and here adapted to test the gantry rotation angle with no additional portal images. This new method uses a test-object patented by QualiFormeD5 and is integrated in the QUALIMAGIQ software platform developed to automatically analyze images acquired for quality control of medical devices.

    We evaluated the occurrence of intestinal parasites and commensals among children and adults from a landless camping in the rural area of Uberlândia, State of Minas Gerais, Brazil, from October to November 2001. Stool samples from 78 individuals were examined by both the Baermann-Moraes and Lutz methods. Fifty-one (65.4%; CI 54.8 - 76.0) individuals were found to be infected, 23 (45.1%) children and 28 (54.9%) adults, of whom 34 (66.7%) were mono-infected, 9 (17.6%) bi-infected, and 8 (15.7%) poly-infected. In conclusion, the high prevalence of intestinal parasites and commensals suggests that parasitological exams should be periodically carried out in addition to the sanitation education and health special care in this population.

    Although the number of fish species that have been studied for both hypoxia/anoxia tolerance and ammonia tolerance are few, there appears to be a correlation between the ability to survive these two insults. After establishing this correlation with examples from the literature, and after examining the role Peter Lutz played in catalyzing this convergent interest in two variables, this article explores potential mechanisms underpinning this correlation. We draw especially on the larger body of information for two human diseases with the same effected organ (brain), namely stroke and hepatic encephalopathy. While several dissimilarities exist between the responses of vertebrates to anoxia and hyperammonemia, one consistent observation in both conditions is an overactivation of NMDA receptors or glutamate neurotoxicity. We propose a glutamate excitotoxicity hypothesis to explain the correlation between ammonia and hypoxia resistance in fish. Furthermore, we suggest several experimental paths to test this hypothesis.

    The goal of this survey was to analyze the spatio-temporal distribution patterns of Culicoides Latreille species (Diptera: Ceratopogonidae) and their relationship with environmental variables in Salta, northwestern Argentina. Culicoides were collected monthly from January 2003 through December 2005. The influence of the climatic variables on population abundance was analyzed with a multilevel Poisson regression. A total of 918 specimens belonging to five species were collected. The most abundant species was Culicoides paraensis Goeldi (65.5%), followed by Culicoides lahillei Iches (14.6%) and Culicoides debilipalpis Lutz (7.6%). The highest seasonal abundance for C. paraensis, C. debilipalpis and C. lahillei occurred during the spring and summer. A Poisson regression analysis showed that the mean maximum and minimum temperature and the mean maximum and minimum humidity were the variables with the greatest influence on the population abundance of Culicoides species.

    Since the description of Lutzomyia longipalpis by Lutz and Neiva more than 100 years ago, much has been written in the scientific literature about this phlebotomine species. Soares and Turco (2003) and Lainson and Rangel (2005) have written extensive reviews focused on vector-host-parasite interactions and American visceral leishmaniasis ecology. However, during the last two decades, the success of Lu. longipalpis in colonising urban environments and its simultaneous geographical spreading have led to new theoretical and operational questions. Therefore, this review updates the general information about this species and notes the more challenging topics regarding the new scenario of urbanisation-spreading and its control in America. Here, we summarise the literature on these issues and the remaining unsolved questions, which pose recommendations for operational research.

  19. Polymer Models of Interphase Chromosomes

    Experiments during interphase, the growth phase of the cell cycle in eukaryotic cells, have shown that parts of chromosomes are tethered to the nuclear periphery[1]. Using a simple polymer model of interphase chromosomes that includes tethering, we compute the probability distribution for the distance between two marked points on the chromosome. These calculations are inspired by recent experiments with two or more fluorescent markers placed along the chromosome[2]. We demonstrate how experiments of this kind, in conjunction with simpe polymer models, can be used to systematically dissect the spatial organization of interphase chromosomes in the nucleus of living cells. This comparison of theory with experiments has lead to the conclusion that the structure of chromosome III in yeast is consistent with a 10nm-fiber model of chromatin. [1]Wallace F. Marshall.

    The sandfly Lutzomyia longipalpis (Lutz and Neiva, 1912) is the main vector of American Visceral Leishmaniasis. In spite of its medical importance and several studies concerning adult digestive physiology, biochemistry and molecular biology, very few studies have been carried out to elucidate the digestion in sandfly larvae. Even the breeding sites and food sources of these animals in the field are largely uncharacterized. In this paper, we describe and characterize several carbohydrases from the gut of L. longipalpis larvae, and show that they are probably not acquired from food. The enzyme profile of this insect is consistent with the digestion of fungal and bacterial cells, which were proved to be ingested by larvae under laboratory conditions. In this respect, sandfly larvae might have a detritivore habit in nature, being able to exploit microorganisms usually encountered in the detritus as a food source.

    Calculation of photoelectron angular distribution asymmetry parameters for photodetachment precesses is a more stringent test for theory than calculation of partial or total cross sections. Since asymmetry parameters involve ratios of transition matrix elements of different channels, they are particularly sensitive to the resonance behavior of transition matrix elements. We present the asymmetry parameters for photodetachment of Li^- (2s^2 ^1S) and Al^- (3s^23p^2 ^3P) using the eigenchannel R-matrix method(U.Fano and C.M. Lee, Phys. Rev. Lett. 31), 1573 (1973)^,(C.H. Greene, in Fundamental Processes of Atomic Dynamics,) edited by J.S. Briggs, H. Kleinpoppen, and H.O. Lutz (Plenum, New York, 1988), pp.105-127.. Our results are in good agreement with the available Al^- photodetachment measurements(A.M. Covington et al.), U of Nevada-Reno, private communication..

  2. Focused attention, open monitoring and automatic self-transcending: Categories to organize meditations from Vedic, Buddhist and Chinese traditions.

    2010-12-01

    This paper proposes a third meditation-category--automatic self-transcending--to extend the dichotomy of focused attention and open monitoring proposed by Lutz. Automatic self-transcending includes techniques designed to transcend their own activity. This contrasts with focused attention, which keeps attention focused on an object; and open monitoring, which keeps attention involved in the monitoring process. Each category was assigned EEG bands, based on reported brain patterns during mental tasks, and meditations were categorized based on their reported EEG. Focused attention, characterized by beta/gamma activity, included meditations from Tibetan Buddhist, Buddhist, and Chinese traditions. Open monitoring, characterized by theta activity, included meditations from Buddhist, Chinese, and Vedic traditions. Automatic self-transcending, characterized by alpha1 activity, included meditations from Vedic and Chinese traditions. Between categories, the included meditations differed in focus, subject/object relation, and procedures. These findings shed light on the common mistake of averaging meditations together to determine mechanisms or clinical effects.

    Moore, J; Velarde, E; Wong, J

    2014-06-01

    Purpose: Precision delivery of radiation dose relies on accurate knowledge of the machine isocenter under a variety of machine motions. This is typically determined by performing a Winston-Lutz test consisting of imaging a known object at multiple gantry/collimator/table angles and ensuring that the maximum offset is within specified tolerance. The first step in the Winston-Lutz test is careful placement of a ball bearing at the machine isocenter as determined by repeated imaging and shifting until accurate placement has been determined. Conventionally this is performed by adjusting a stage manually using vernier scales which carry the limitation that each adjustment must be done inside the treatment room with the risks of inaccurate adjustment of the scale and physical bumping of the table. It is proposed to use a motorized system controlled outside of the room to improve the required time and accuracy of these tests. Methods: The three dimensional vernier scales are replaced by three motors with accuracy of 1 micron and a range of 25.4mm connected via USB to a computer in the control room. Software is designed which automatically detects the motors and assigns them to proper axes and allows for small shifts to be entered and performed. Input values match calculated offsets in magnitude and sign to reduce conversion errors. Speed of setup, number of iterations to setup, and accuracy of final placement are assessed. Results: Automatic BB placement required 2.25 iterations and 13 minutes on average while manual placement required 3.76 iterations and 37.5 minutes. The average final XYZ offsets is 0.02cm, 0.01cm, 0.04cm for automatic setup and 0.04cm, 0.02cm, 0.04cm for manual setup. Conclusion: Automatic placement decreased time and repeat iterations for setup while improving placement accuracy. Automatic placement greatly reduces the time required to perform QA.

    Machine Performance Check (MPC) is an automated and integrated image-based tool for verification of beam and geometric performance of the TrueBeam linac. The aims of the study were to evaluate the performance of the MPC geometric tests relevant to OBI/CBCT IGRT geometric accuracy. This included evaluation of the MPC isocenter and couch tests. Evaluation was performed by comparing MPC to QA tests performed routinely in the department over a 4-month period. The MPC isocenter tests were compared against an in-house developed Winston-Lutz test and the couch compared against routine mechanical QA type procedures. In all cases the results from the routine QA procedure was presented in a form directly comparable to MPC to allow a like-to-like comparison. The sensitivity of MPC was also tested by deliberately miscalibrating the appropriate linac parameter. The MPC isocenter size and MPC kV imager offset were found to agree with Winston-Lutz to within 0.2 mm and 0.22 mm, respectively. The MPC couch tests agreed with routine QA to within 0.12 mm and 0.15°. The MPC isocenter size and kV imager offset parameters were found to be affected by a change in beam focal spot position with the kV imager offset more sensitive. The MPC couch tests were all unaffected by an offset in the couch calibration but the three axes that utilized two point calibrations were sensitive to a miscalibration of the size in the span of the calibration. All MPC tests were unaffected by a deliberate misalignment of the MPC phantom and roll of the order of one degree.

    Purpose: To evaluate the spatial variations of multiple off-axial targets for a single isocenter stereotactic radiosurgery (SRS) treatment plan in ExacTrac 6D robotic couch system (BrainLab AG). Methods: Five metallic ball bearing (BB) markers were placed sparsely in 3D off-axial locations (non-coplanar) inside a skull phantom as the representatives of multiple targets mimicking multiple brain metastases. The locations of the BB markers were carefully chosen to minimize overlapping of each other in a port imaging detector plane. The skull phantom was immobilized by a frameless mask and CT scanned with a BrainLab Head and Neck Localizer using a GE Optima MDCT scanner. The CT images were exported to iPlan software (BrainLab AG) and a multiple target PTV was drawn by combining all the contours of the BBs. The margin of the MLC opening was selected as 3 mm expansion outward. Two coplanar arc beams were placed to generate a single isocenter SRS plan to treat the PTV. The arc beams were delivered using Novalis Tx system with portal imaging acquisition mode per 10% temporal resolution. The locations of the BBs were visualized and analyzed with respect to the MLC aperture in the treatment plan similar to the Winston-Lutz test. Results: All the BBs were clearly identified inside the MLC openings. The positional errors for the BBs were overall less than 1 mm along the rotational path of the two arcs. Conclusion: This study verified that the spatial deviations of multiple off-axial targets for a single isocenter SRS treatment plan is within sub-millimeter range in ExacTrac 6D robotic couch system. Accompanied with the Winston-Lutz test, this test will quality-assure the spatial accuracies of the isocenter as well as the positions of multiple off-axial targets for the SRS treatment using a single isocenter multiple target treatment plan.

    Ectopia cordis is a pathology in which the heart is complete or partially outside of the thoracic cavity. It represents a challenge for the diagnosis and handling because of its high perinatal mortality. We present the first case of thoracic ectopia cordis with prenatal diagnostic (27th week), its multidisciplinary handling at Hospital de Ginecopediatria núm. 71 of the Centro Medico Nacional Adolfo Ruiz Cortines, IMSS, in Veracruz, Mexico. We communicate the case of a 24 year-old woman referred by her correspondent medical unit with the diagnosis of 23.6 weeks pregnancy with suspicion of heart malformation by ultrasound. The pregnancy was followed-up until the 38th week, when it was programmed a caesarean section. The newborn had ectopia cordis, which was treated at the moment of birth. In this article, we present pictures of the heart defect as well as its evolution. The up-to-date bibliography is revised about the medical profile and treatment. The handling of the ectopia cordis includes an appropriate prenatal diagnosis through echocardiograph, a multidisciplinary perinatal team, to program the caesarean operation, aseptic handling of the newborn, immediate correction of the wall defect with skin torn piece without trying to correct the costal grill, specific hemodynamic cares, to reprogramme a correction of associated defects.

    Clinical data were collected in 194 cases of jaundiced patients treated at the "Adolfo Lopez Mateos" ISSSTE Hospital in Mexico City from July 1985 to July 1986. A copy of the clinical history of each patient was given to each of four physicians--one recently graduated from medical school, another in his first year of gastroenterology, and two others who were experienced gastroenterologists. The same clinical data were processed by a computer set up to use a modified Danish COMIC algorithm. All physicians and the computer technician were blinded to the "gold standard" pathologic diagnoses, with which their diagnoses were compared. Accuracy rates of the physicians in distinguishing intrahepatic (medical) from extrahepatic (surgical) jaundice were 78%, 86%, 86%, and 91%, and the accuracy of computer-assisted diagnoses was 96%. Chi-squared analysis of the diagnoses of three of the physicians and those of the computer showed significant differences (p between 0.1 and 0.01). For the diagnoses of the remaining physician, however, no significant difference was found after chi-squared continuity correction.

    This conference report of the Centro de Estudios Migratorios Latinoamericanos and the Center for Migration Studies pertains to meetings held in August 1992. Summary information on migration movements in Latin America is presented by region and subject. The topic of integration in the Americas was presented by Mr. Lelio Marmora. Other topics and presenters include the new Colombian Migration Policy (Mr. Carlos Adolfo Arenas), the integration policies in Central America (Mr. Pilar Norza of Costa Rica, Raimundo Alvarado of El Salvador, and Luis Armando Gusman of Nicaragua), the Andean Pact agreements (representatives of each country), US immigration policy (Charles B. Keely), the Mexican integration with Latin America and immigration to the US (Jorge Bustamante), migration to Bolivia and Argentina and Chile, and transnationalism in the Caribbean (Professor Andre Corten). Migration policy needs to be tailored specifically to the situation in Latin America, and greater attention needs to be devoted to labor migrants' rights and working conditions. There are still fundamental differences among countries in policies regarding the free circulation of persons across borders. There is a division among those who support migration and those who are realists. National sovereignty issues are solvable because of a common national past and a relatively homogenous population. Another opinion is that Latin America is more diverse than commonly recognized. Capital is protected more in international agreements than is migrant labor. Regional integration for the US does mean immigration from Mexico. The US sees Mexican migration as a policy problem, and Mexico sees migration as a labor opportunity.

    In this work has been studied the effects of the transport properties of biodiesel derived from soybean on the mixing process, using a CFD code OpenFOAM. For this the most relevant properties in this mixing process have been determined: density, viscosity, surface tension and vapor pressure. These fuel properties govern the spray formation however, there are only very limited studies that determined for its subsequent implementation in a CFD code, such as the OpenFOAM code. Such properties were obtained using empirical correlations based on the molecular structure of the fatty acids that compose the biodiesel and applying nonlinear regression are implemented in the programed models used in the OpenFOAM code for a diesel spray simulation. The results achieved in the present study on the one side, have been confirmed how the biodiesel properties affect the mixture process, and on the other side, the obtained coefficients which can be used in the proposed models by the CFD code OpenFOAM for the implementation of this properties as a temperature function without the correlations based on the molecular structure of the fatty acid. Also they thank the CONACYT from Mexican Government for granting the Master degree of Adolfo Benitez.

  17. Bias Properties of Extragalactic Distance Indicators. XI. Methods to Correct for Observational Selection Bias for RR Lyrae Absolute Magnitudes from Trigonometric Parallaxes Expected from the Full-Sky Astrometric Mapping Explorer Satellite

    NASA Astrophysics Data System (ADS)

    Sandage, Allan; Saha, A.

    2002-04-01

    A short history is given of the development of the correction for observation selection bias inherent in the calibration of absolute magnitudes using trigonometric parallaxes. The developments have been due to Eddington, Jeffreys, Trumpler & Weaver, Wallerstein, Ljunggren & Oja, West, Lutz & Kelker, after whom the bias is named, Turon Lacarrieu & Crézé, Hanson, Smith, and many others. As a tutorial to gain an intuitive understanding of several complicated trigonometric bias problems, we study a toy bias model of a parallax catalog that incorporates assumed parallax measuring errors of various severities. The two effects of bias errors on the derived absolute magnitudes are (1) the Lutz-Kelker correction itself, which depends on the relative parallax error δπ/π and the spatial distribution, and (2) a Malmquist-like ``incompleteness'' correction of opposite sign due to various apparent magnitude cutoffs as they are progressively imposed on the catalog. We calculate the bias properties using simulations involving 3×106 stars of fixed absolute magnitude using Mv=+0.6 to imitate RR Lyrae variables in the mean. These stars are spread over a spherical volume bounded by a radius 50,000 pc with different spatial density distributions. The bias is demonstrated by first using a fixed rms parallax uncertainty per star of 50 μas and then using a variable rms accuracy that ranges from 50 μas at apparent magnitude V=9 to 500 μas at V=15 according to the specifications for the Full-Sky Astrometric Mapping Explorer (FAME) satellite to be launched in 2004. The effects of imposing magnitude limits and limits on the ``observer's'' error, δπ/π, are displayed. We contrast the method of calculating mean absolute magnitude directly from the parallaxes where bias corrections are mandatory, with an inverse method using maximum likelihood that is free of the Lutz-Kelker bias, although a Malmquist bias is present. Simulations show the power of the inverse method. Nevertheless, we

    The diagnostic categories of the patients discharged from the "Hospital das Clínicas" of the University of São Paulo in 1989 were arranged according the International Classification of Diseases (I.C.D.) and analysed. In each Group sex, age and the reason of discharge or death was indicated. The data concerning 39,601 cases were provided by the Medical Data Service of the "Instituto Central" of the "Hospital das Clínicas". Only the principal diagnosis was taken into account. In the "Instituto de Psiquiatria" most the patients (55.4%) were males between 20 and 49 years of age. The main diagnostic categories were affective psychoses (20.3%), schizophrenic disorders (15%), and disorders related to alcoholism (9.5%). The mortality rate was 0.27%. In the "Instituto da Criança" 56% of the patients that left the hospital were male children and 45.8% of them were less than one year old. Regarding to the diagnostic categories the most important one was that of the diseases of the respiratory system with 27.1% of cases, followed by that of infectious and parasitic diseases with 16.0% of cases. Within the respiratory diseases the most important were the pneumonias caused by not specified microorganisms, and within the infectious diseases the most important was the diarrhea of presumably infectious origin. The mortality rate in this Institute was 9.4%. The "Instituto de Ortopedia e Traumatologia" left 3,825 patients 61.7% males, and 46.9% of them were aged between 20 and 49 years. The greatest number of cases (57.1%) belonged to the Chapter "Injury and Poisoning" followed by that of "Diseases of the Muscoleskeletal System" and Connective Tissue Diseases (23.5%). In this Institute the mortality rate was 1.2%. From the "Instituto do Coração" 7,194 patients were discharged; 65% of them were males, varying their age between 50 and 69 years. The diseases of the circulatory system were mostly ischemic heart disease, miocardiopathies and rheumatic heart diseases. Mortality rate

    Purpose: Quality assurance is an essential task in radiotherapy that often requires many manual tasks. We investigate the use of an event driven framework in conjunction with software agents to automate QA and eliminate wait times. Methods: An in house developed subscription-publication service, EventNet, was added to the Aria OIS to be a message broker for critical events occurring in the OIS and software agents. Software agents operate without user intervention and perform critical QA steps. The results of the QA are documented and the resulting event is generated and passed back to EventNet. Users can subscribe to those events and receive messages based on custom filters designed to send passing or failing results to physicists or dosimetrists. Agents were developed to expedite the following QA tasks: Plan Revision, Plan 2nd Check, SRS Winston-Lutz isocenter, Treatment History Audit, Treatment Machine Configuration. Results: Plan approval in the Aria OIS was used as the event trigger for plan revision QA and Plan 2nd check agents. The agents pulled the plan data, executed the prescribed QA, stored the results and updated EventNet for publication. The Winston Lutz agent reduced QA time from 20 minutes to 4 minutes and provided a more accurate quantitative estimate of radiation isocenter. The Treatment Machine Configuration agent automatically reports any changes to the Treatment machine or HDR unit configuration. The agents are reliable, act immediately, and execute each task identically every time. Conclusion: An event driven framework has inverted the data chase in our radiotherapy QA process. Rather than have dosimetrists and physicists push data to QA software and pull results back into the OIS, the software agents perform these steps immediately upon receiving the sentinel events from EventNet.

  15. Medical Genetics and the First Studies of the Genetics of Populations in Mexico.

    PubMed

    Barahona, Ana

    2016-09-01

    Following World War II (WWII), there was a new emphasis within genetics on studying the genetic composition of populations. This probably had a dual source in the growing strength of evolutionary biology and the new international interest in understanding the effects of radiation on human populations, following the atomic bombings in Japan. These global concerns were shared by Mexican physicians. Indeed, Mexico was one of the leading centers of this trend in human genetics. Three leading players in this story were Mario Salazar Mallén, Adolfo Karl, and Rubén Lisker. Their trajectories and the international networks in human genetics that were established after WWII, paved the way for the establishment of medical and population genetics in Mexico. Salazar Mallén's studies on the distribution and characterization of ABO blood groups in indigenous populations were the starting point while Karl's studies on the distribution of abnormal hemoglobin in Mexican indigenous populations showed the relationships observed in other laboratories at the time. It was Lisker's studies, however, that were instrumental in the development of population genetics in the context of national public policies for extending health care services to the Mexican population. In particular, he conducted studies on Mexican indigenous groups contributing to the knowledge of the biological diversity of human populations according to international trends that focused on the variability of human populations in terms of genetic frequencies. From the start, however, Lisker was as committed to the reconstruction of shared languages and practices as he was to building networks of collaboration in order to guarantee the necessary groundwork for establishing the study of the genetics of human populations in Mexico. This study also allows us to place Mexican science within a global context in which connected narratives describe the interplay between global trends and national contexts.

    Nocturnal activity of the sand fly Lutzomyia longipalpis (Lutz & Neiva) was studied from August 1991 to July 1992 in a small rural community in Colombia where American visceral leishmaniasis is endemic. During 2 or 3 nights each month, sand flies were collected with hand-held aspirators each hour between 1730 and 0630 hours, from a pigpen and a cattle corral located 30 m apart. Host-seeking activity of L. longipalpis adults was characterized by 2 general patterns: (1) adult sand fly activity increased shortly after sunset and continued until just after sunrise, and (2) peak sand fly activity was greatest early in the evening (1830-2330 hours) and then declined steadily toward morning. Female L. longipalpis activity generally increased after 2030 hours, whereas that of males remained constant or declined as the evening progressed. There were seasonal differences in sand fly abundance between the 2 sites: peak abundance in the cattle corral occurred during hot, dry periods, whereas maximum abundance in the pigpen occurred when relative humidity was higher. Influence of relative humidity on activity varied with season. Sand fly activity tended to decrease at temperatures below 24 degrees C and increase in the presence of moonlight.

    Leishmania infantum, the causative agent of visceral leishmaniasis (VL) in Brazil, is spread mostly by the bite of the sand fly Lutzomyia longipalpis (Lutz & Neiva). We trapped sand flies in endemic neighborhoods near Natal, Brazil, where cases of human and dog VL were documented. Amplification of species-specific cytochrome b (Cyt b) genes by polymerase chain reaction revealed that sand flies from rural and periurban areas harbored blood from different sources. The most common source ofbloodmeal was human, but blood from dog, chicken, and armadillo was also present. We tested the preference for a source of bloodmeal experimentally by feeding L. longipalpis F1 with blood from different animals. There were significant differences between the proportion of flies engorged and number of eggs laid among flies fed on different sources, varying from 8.4 to 19 (P < 0.0001). Blood from guinea pig or horse was best to support sand fly oviposition, but human blood also supported sand fly oviposition well. No sand flies fed on cats, and sand flies feeding on the opossum Monodelphis domestica Wagner produced no eggs. These data support the hypothesis that L. longipalpis is an eclectic feeder, and humans are an important source of blood for this sand fly species in periurban areas of Brazil.

    Ecological studies on the sand fly Lutzomyia longipalpis (Lutz & Neiva) were conducted during 1990-1993 in a small rural community in Colombia where American visceral leishmaniasis is endemic. Standardized weekly sand fly collections made from pigpens and natural resting sites displayed a bimodal annual abundance cycle, with a small peak occurring in October-November and a larger one in April-May. Time series analysis was employed to quantify the associations between sand fly abundance and weather factors (temperature, relative humidity, and rainfall). In addition to a prominent 6-mo cycle. Fourier analysis of the collection data demonstrated that the L. longipalpis population also exhibited a 5- to 8-wk cycle that may represent the length of larval development. Autoregressive moving average models were fit to weekly collection data and their residuals were regressed against rainfall, temperature, and relative humidity. A significant positive association between female L. longipalpis abundance and the relative humidity and rainfall recorded 3 wk earlier was found, indicating that these factors may be of value in predicting sand fly abundance. Additionally, these data indicated that L. longipalpis larvae may become quiescent during adverse conditions.

    The resurgence of visceral leishmaniasis in Brazil increases the need for studies to elucidate the spatial and temporal dynamics of Lutzomyia longipalpis (Lutz and Neiva) (Diptera: Psychodidae), the vector of Leishmania infantum, the causative agent of visceral leishmaniasis in Brazil. Sand flies were captured in peridomestic habitats biweekly for 3 yr. Cross-correlation tests and spectral analysis were used to analyze the simultaneous and lag-time correlations between Lu. longipalpis population densities and abiotic factors of temperature, relative humidity, wind velocity, and rainfall. Distinct seasonal patterns were observed for males and females, with intervals of 6 mo between population peaks for males and 12 mo for females. Peak female population densities lagged 3 mo behind the maximum annual temperature. Female population density was negatively correlated with relative humidity. An increase in average wind velocity was followed by a decrease in the number of females for 2 wk. Understanding the relationship between the seasonal population dynamics of Lu. longipalpis and abiotic factors will contribute to the design of better control measures to decrease transmission of L. infantum and consequently the incidence of leishmaniasis.

    SUMMARY Strongyloidiasis is a potentially serious infection in immunocompromised patients. Thus, the availability of sensitive and specific diagnostic methods is desirable, especially in the context of immunosuppressed patients in whom the diagnosis and treatment of strongyloidiasis is of utmost importance. In this study, serological and molecular tools were used to diagnose Strongyloides stercoralis infections in immunosuppressed patients. Serum and stool samples were obtained from 52 patients. Stool samples were first analyzed by Lutz, Rugai, and Agar plate culture methods, and then by a quantitative real time polymerase chain reaction (qPCR). Serum samples were evaluated by an enzyme-linked immunosorbent assay (ELISA) using a soluble (AS) or a membrane fractions antigen (AM) obtained from alkaline solutions of the filariform larvae of Strongyloides venezuelensis. Of the 52 immunosuppressed patients, three (5.8%) were positive for S. stercoralis by parasitological methods, compared to two patients (3.8%) and one patient (1.9%) who were detected by ELISA using the AS and the AM antigens, respectively. S. stercoralis DNA was amplified in seven (13.5%) stool samples by qPCR. These results suggest the utility of qPCR as an alternative diagnostic tool for the diagnosis of S. stercoralis infection in immunocompromised patients, considering the possible severity of this helminthiasis in this group of patients.

  1. How fruit flies came to launch the chromosome theory of heredity.

    PubMed

    Carlson, Elof Axel

    2013-01-01

    Fruit flies were used by several laboratories between 1901 and 1910 for studies of experimental evolution at Harvard, Indiana University, and Cold Spring Harbor before Thomas Hunt Morgan found his white-eyed mutation that we associate with the beginnings of the fly lab at Columbia University. The major players prior to Morgan were William Castle and his students at Harvard University, Frank Lutz at Cold Spring Harbor, and Fernandus Payne whose ideas for working with fruit flies were shaped by his studies of blind cave fauna at Indiana University. Payne's interests were stimulated by the work of Carl Eigenmann, an authority on blind cave fauna, and William Moenkhaus, who introduced Payne to fruit flies at Indiana University before Payne moved to Columbia to pursue graduate work with Morgan and Edmund Wilson. The motivations of the laboratories differed in the theories used for their work. Castle spread the word about the utility of fruit flies for research, but Payne gave Morgan his first fruit flies for research leading to the discovery of the white-eye mutation.

    Culicoides insignis Lutz is incriminated as a vector of bluetongue virus (BTV) to ruminants in America. In South America, almost all countries have serological evidence of BTV infections, but only four outbreaks of the disease have been reported. Although clinical diseases have never been cited in Argentina, viral activity has been detected in cattle. In this study, we developed a potential distribution map of Culicoides insignis populations in northwestern Argentina using Maximum Entropy Modeling (Maxent). For the analyses, information regarding both data of specimen collections between 2003 and 2013, and climatic and environmental variables was used. Variables selection was based on the ecological relevance in relation to Culicoides spp. biology and distribution in the area. The best Maxent model according to the Jackknife test included 53 C. insignis presence records and precipitation of the warmest quarter, altitude, and precipitation of the wettest month. Accuracy was evaluated by the area under the curve (AUC = 0.97). These results provide an important analytical resource of high potential for both the development of suitable control strategies and the assessment of disease transmission risk in the region.

Masked long-chain alpha-hydroxyaldehydes were trapped in all subcellular fractions of bovine liver by application of pentafluorbenzyloxime derivatization [van Kuijk, Thomas, Stephens and Dratz (1986) Biochem. Biophys. Res. Commun. 139, 144-149] and quantified via GLC/MS using characteristic ion traces. 2. The chain-length profile of long-chain 2-hydroxyalkanales clearly indicates their relationship to plasmalogens as precursor molecules. 3.

The constant oxidation rate of plasmalogens in all subcellular fractions provides conclusive evidence for a non-enzymic plasmalogen epoxidation process (probably via hydroperoxy radicals). 5.

  4. From "forest malaria" to "bromeliad malaria": a case-study of scientific controversy and malaria control.

    The article analyses the evolution of knowledge and rationale of control of a special case of malaria transmission based on Bromelia-Kerteszia complex. Since bromeliaceae function as a 'host of the carrier' and were previously associated with natural forests, the elucidation of bromeliad malaria historically elicited controversies concerning the imputation of Kertesziae as transmitters as well as over control strategies directed to bromelia eradication (manual removal, herbicides and deforestation), use of insecticides and chemoprophylaxis. Established authority, disciplinary traditions, conceptual premises and contemporary criteria for validating knowledge in the field partly explain the long time gap since Adolpho Lutz announced at the beginning of the century the existence of a new mosquito and breeding site as responsible for a 'forest malaria' epidemic occurring at a high altitude. The article brings attention to how economic, political and institutional determinants played an important role in redefining studies that led both in Trinidad and Brazil to the recognition of the importance of kerteszia transmission, including urban areas, and establishing new approaches to its study, most relevant of all the concurrence of broad ecological research. The article then describes the Brazilian campaign strategies which showed significant short-term results but had to wait four decades to achieve the goal of eradication due to the peculiar characteristics of this pathogenic complex. Finally, it brings attention to the importance of encompassing social values and discourses, in this case, environmental preservation, to understanding historical trends of malaria control programs.

    We evaluated the directional asymmetry between right and left wings and quantified the intraspecific and interspecific variation of the wing shape of 601 specimens of the genus Diachlorus to determine to what extent the geometrical variation discriminates six species distributed in six protected areas of Colombia. Geometric analyses were performed, integrating Procrustes methods, principal component analyses, cluster analyses, linear and quadratic discriminant analyses, and evaluations of shape changes. In Diachlorus, left and right wings did not present significant asymmetry but a geometrical analysis was allowed for species identification and, in some cases, the origin of the specimens using the variation of wing shape; the best-assigned species was Diachlorus leticia Wilkerson & Fairchild, while the worst was Diachlorus jobbinsi Fairchild, which also had the highest intraspecific variation, while Diachlorus fuscistigma Lutz had the lowest variation. Diachlorus fuscistigma and Diachlorus leucotibialis Wilkerson & Fairchild were the most similar species, while D. leucotibialis and Diachlorus nuneztovari Fairchild & Ortiz were the most disimilar. The specimens with the most different wing shape belonged to Chocó (especially those of D. jobbinsi), the geographically farthest area from the others in the study; however, no correlation was observed between geometric and geographical distances. Linear discriminants were better than nonlinear (quadratic) discriminant analyses in predicting species membership, but the opposite was true for predicting area membership. Based on our data, we hypothesized that other species of Diachlorus could also be discriminated using geometric morphometry of the wing shape.

  6. Defeating diplostomoid dangers in USA catfish aquaculture.

    2004-06-01

    Diplostomoid digenean metacercariae have caused widescale mortalities of channel catfish, Ictalurus punctatus (Rafinesque), at aquaculture farms in Louisiana, Mississippi and Arkansas, USA. Originally, based on a tentative diagnosis, the industry considered the primary harmful agent to be an introduced species from Europe, Bolbophorus confusus (Krause, 1914), frequently reported from the American white pelican, Pelecanus erythrorhynchos Gmelin. Our group has now shown, using ITS 1-2 plus three more-conservative gene fragments, that two sympatric species of Bolbophorus exist in the American white pelican. One, B. damnificus Overstreet et Curran, 2002, infects the musculature of catfish, and the other, probably not B. confusus, does not infect catfish. However, at least four other pathogenic diplostomoids and a clinostomoid infect the catfish, and they use at least four different snail hosts, including the planorbids Planorbella trivolvis (Say) and Gyraulus parvus (Say), the physid Physella gyrina (Say) and a lymnaeid. Two metacercariae, B. damnificus and Bursacetabulus pelecanus Dronen, Tehrany et Wardle, 1999, infect the catfish and mature in the pelican; two others, Austrodiplostomum compactum (Lutz, 1928) and Hysteromorpha cf. triloba (Rudolphi, 1819), mature in cormorants; one, Diplostomum sp., matures in seagulls and at least one, Clinostomum marginatum (Rudolphi, 1819), matures in herons, egrets and other wading birds. Consequently, management of catfish ponds relative to digenean infections requires considerable biological information on the fish, bird, and snail hosts as well as the parasites.

    Chemical insecticides are effective for controlling Lutzomyia and Phlebotomus sand fly (Diptera: Psychodidae) vectors of Leishmania parasites. However, repeated use of certain insecticides has led to tolerance and resistance. The objective of this study was to determine lethal concentrations (LCs) and lethal exposure times (LTs) to assess levels of susceptibility of laboratory Lutzomyia longipalpis (Lutz and Nieva) and Phlebotomus papatasi (Scopoli) to 10 insecticides using a modified version of the World Health Organization (WHO) exposure kit assay and Centers for Disease Control and Prevention (CDC) bottle bioassay. Sand flies were exposed to insecticides coated on the interior of 0.5-gallon and 1,000-ml glass bottles. Following exposure, the flies were allowed to recover for 24 h, after which mortality was recorded. From dose–response survival curves for L. longipalpis and P. papatasi generated with the QCal software, LCs causing 50, 90, and 95% mortality were determined for each insecticide. The LCs and LTs from this study will be useful as baseline reference points for future studies using the CDC bottle bioassays to assess insecticide susceptibility of sand fly populations in the field. There is a need for a larger repository of sand fly insecticide susceptibility data from the CDC bottle bioassays, including a range of LCs and LTs for more sand fly species with more insecticides. Such a repository would be a valuable tool for vector management. PMID:26336231

  8. Spatial distribution and environmental factors associated to phlebotomine fauna in a border area of transmission of visceral leishmaniasis in Mato Grosso do Sul, Brazil

    2014-01-01

    Background Mato Grosso do Sul has been undergoing a process of urbanization which results in loss of native vegetation. This withdrawal makes vectors of man and domestic animals closer, causing changes in the epidemiology of diseases such as American Visceral Leishmaniasis. The aim of the study was to evaluate the phlebotomine fauna and environmental issues related to the transmission of AVL in Ponta Porã, Mato Grosso do Sul, between 2009 and 2010. Methods Vegetation of the urban area was evaluated by Normalized Difference Vegetation Index (NDVI), Normalized Difference Water Index (NDWI) and Soil Adjusted Vegetation Index (SAVI). Results The results showed that the phlebotomine fauna of the city consists of five species, especially Lutzomyia longipalpis (Lutz and Neiva, 1912), the vector of Leishmania (Leishmania) infantum. Predominance of males was observed. The insects were captured in greater quantity in the intradomicile. Lu. longipalpis was the most frequent and abundant species, present throughout the year, with a peak population after the rainy season. Vectors can be found in high amounts in forest and disturbed environments. Conclusions The finding of Lu. longipalpis in regions with little vegetation and humidity suggests that the species is adapted to different sorts of environmental conditions, demonstrating its close association with man and the environment it inhabits. The tourist feature of Ponta Porã reinforces its epidemiological importance as a vulnerable city. The geographical location, bordering Paraguay through dry border, makes possible the existence of a corridor of vectors and infected dogs between the two countries. PMID:24898032

    The German naturalist Carl Hermann Conrad Burmeister (1807-1892) had a prolific scientific career, spanning multiple taxa from diverse insect groups and trilobites to temnospondyls, birds, and extant and fossil mammals (see Berg, 1895). His contributions to anuran taxonomy are concentrated in two books, "Erläuterungen zur Fauna Brasiliensis…" (Burmeister, 1856) and "Reise durch die La Plata-Staaten…" (Burmeister, 1861). The latter is an account of his travels in Argentina and Uruguay from 1857-1860 and includes descriptions of three new species of frogs: Leiuperus nebulosus, Cystignathus mystacinus, and Hyla leucotaenia. While the first two names currently designate valid species, with the combinations Pleurodema nebulosum and Leptodactylus mystacinus respectively, the last name has had a more complex taxonomic history. It involves confusions involving a homonym, its consideration as a junior synonym of Hypsiboas pulchellus (Duméril & Bibron, 1841)-a widely distributed species in eastern Argentina, southeastern Brazil, and Uruguay (Frost, 2014)-and its actual identity corresponding to another widespread species in the same geographic area, with which it has never before been associated: Scinax squalirostris (A. Lutz, 1925). All these issues are discussed in this paper.

    Abstract Background A revised list of the mosquitoes (Diptera: Culicidae) known to occur in Colombia is presented. A total of 324 species from 28 genera of Culicidae are included. The species names are organized in alphabetical order according to the current generic and subgeneric classification, along with their authorship. The list is compiled in order to support mosquito research in Colombia. New information Our systematic review and literature survey found, by 16 February 2015, 13 records of culicid species previously overlooked by mosquito catalogs for Colombia: Anopheles costai da Fonseca & da Silva Ramos, 1939, An. fluminensis Root, 1927, An. malefactor Dyar & Knab, 1907, An. shannoni Davis, 1931, An. vargasi Galbadón, Cova García & Lopez, 1941, Culex mesodenticulatus Galindo & Mendez, 1961, Haemagogus capricornii Lutz, 1904, Isostomyia espini (Martini, 1914), Johnbelkinia leucopus (Dyar & Knab, 1906), Mansonia indubitans Dyar & Shannon, 1925, Psorophora saeva Dyar & Knab, 1906, Sabethes glaucodaemon (Dyar & Shannon, 1925), and Wyeomyia intonca Dyar & Knab, 1909. Moreover, Wyeomyia (Dendromyia) luteoventralis Theobald, 1901 is recorded for Colombia for the first time. This work provides important insights into mosquito diversity in Colombia, using the current nomenclature and phylogenetic rankings. PMID:25829860

    Female undergraduate students at two Canadian universities (N = 378) completed the NEO PI-R (Costa, P.T. & McCrae, R.R. (1992). NEO PI-R Professional Manual. Lutz, FL: Psychological Assessment Resources) and the Eating Attitudes Test (EAT-26; Garner, D. M., Olmstead, M. P., Bohr, Y. & Garfinkel, P. E. (1982). The Eating Attitudes Test: Psychometric features and clinical correlates. Psychological Medicine, 12, 871-878.). Eating disorder symptomatic (N = 43) and nonsymptomatic (N = 335) women differed on facets of Neuroticism, Extraversion, and Agreeableness. Among symptomatic women, the Oral Control subscale of the EAT-26 was correlated significantly with facets of Neuroticism, Agreeableness and Conscientiousness. Specifically, the Impulsivity facet of Neuroticism was positively correlated with the Bulimia and Food Preoccupation subscale of EAT-26, but negatively correlated with the Oral Control and Dieting subscales. Overall, results suggest that high scores on Neuroticism may be a risk factor for development of disordered eating behavior and that the degree of Impulsiveness may predict the eating disorder subtype to which one is most susceptible.

    The U.S. Geological Survey has recently measured and sampled the Phosphoria formation at many localities in Idaho and other western states. These data will not be fully synthesized and analyzed for several years, but segments of the data, accompanied by little or no interpretation, are published as preliminary reports as they are assembled. This is the fifth report of data containing abstracts of sections measured in southeastern Idaho; it includes about half of the data gathered in Idaho in 1949. The field and laboratory procedures adopted in these investigations are described rather fully in a previous report (McKelvey and others, 1953a). Many people have taken part in this investigation, which was organized and supervised by V. E. McKelvey. F. J. Anderson, A. L. Bush, R. S. Jones, K. B. Krauskopf, K. Lutz, M. E. Thompson, R. G. Waring, and M. A. Warner participated in the description of strata and the collection of samples referred to in this report. T. K. Rigby assisted in the preparation of trenches and the collection, crushing, and splitting of samples in the field. The laboratory preparation of samples for chemical analysis was done in Denver, Colo., under the direction of W. P. Huleatt.

    Although the phlebotomine sandfly Lutzomyia longipalpis (Lutz & Neiva, 1912) (Diptera: Psychodidae) is generally accepted to be a species complex, it is unclear how many members there are, how they are related and which are the main vectors of leishmaniasis. The vectorial capacity of each sibling species is likely to differ, thus a means of identifying the most important vector species is of critical importance to the epidemiology and control of this debilitating disease in South and Central America. In Brazil four chemotypes have been distinguished by sex pheromone analysis. In this study the sex pheromone extracts of L. longipalpis from six regions of Brazil were analysed in detail. Samples included the sympatric 1-spot, 2-spot and intermediate spot morphotypes from Sobral, Ceará State. The results strongly suggest that members of the complex that produce different sex pheromones are reproductively isolated, thus strengthening the argument that the different chemotypes represent true sibling species. The study also found significant differences in morphology and the amounts of sex pheromone produced by members of each chemotype from different parts of Brazil, which suggests population substructuring that has not previously been recognized. Evidence of a fifth chemotype in Brazil is also presented.

    We present new probabilistic forecasts of the timing of the world's population reaching 8 billion, the world's peak population, and the date at which one-third or more of the world's population would be 60+ years old. The timing of these milestones, as well as the timing of the Day of 7 Billion, is uncertain. We compute that the 60 percent prediction interval for the Day of 8 Billion is between 2024 and 2033. Our figures show that there is around a 60 percent chance that one-third of the world's population would be 60+ years old in 2100. In the UN 2010 medium variant, that proportion never reaches one-third. As in our past forecasts (Lutz et al. 2001, 2008), we find the chance that the world's population will peak in this century to be around 84 percent and the timing of that peak to be highly uncertain. Focal days, like the Day of 7 Billion, play a role in raising public awareness of population issues, but they give a false sense of the certainty of our knowledge. The uncertainty of the timing of demographic milestones is not a constant of nature. Understanding the true extent of our demographic uncertainty can help motivate governments and other agencies to make the investments necessary to reduce it.

    Purpose: The isocenter accuracy of a linear accelerator is often assessed with star-shot films. This approach is limited in its ability to quantify three dimensional wobble of radiation field centers (RFCs). The authors report a Winston-Lutz based method to measure the 3D wobble of RFCs during gantry rotation, collimator rotation, and collimator field size change. Methods: A stationary ball-bearing phantom was imaged using multileaf collimator-shaped radiation fields at various gantry angles, collimator angles, and field sizes. The center of the ball-bearing served as a reference point, to which all RFCs were localized using a computer algorithm with subpixel accuracy. Then, the gantry rotation isocenter and the collimator rotation axis were derived from the coordinates of these RFCs. Finally, the deviation or wobble of the individual RFC from the derived isocenter or rotation axis was quantified. Results: The results showed that the RFCs were stable as the field size of the multileaf collimator was varied. The wobble of RFCs depended on the gantry angle and the collimator angle and was reproducible, indicating that the mechanical imperfections of the linac were mostly systematic and quantifiable. It was found that the 3D wobble of RFCs during gantry rotation was reduced after compensating for a constant misalignment of the multileaf collimator. Conclusions: The 3D wobble of RFCs can be measured with submillimeter precision using the proposed method. This method provides a useful tool for checking and adjusting the radiation isocenter tightness of a linac.

    Strongyloidiasis is a potentially serious infection in immunocompromised patients. Thus, the availability of sensitive and specific diagnostic methods is desirable, especially in the context of immunosuppressed patients in whom the diagnosis and treatment of strongyloidiasis is of utmost importance. In this study, serological and molecular tools were used to diagnose Strongyloides stercoralis infections in immunosuppressed patients. Serum and stool samples were obtained from 52 patients. Stool samples were first analyzed by Lutz, Rugai, and Agar plate culture methods, and then by a quantitative real time polymerase chain reaction (qPCR). Serum samples were evaluated by an enzyme-linked immunosorbent assay (ELISA) using a soluble (AS) or a membrane fractions antigen (AM) obtained from alkaline solutions of the filariform larvae of Strongyloides venezuelensis. Of the 52 immunosuppressed patients, three (5.8%) were positive for S. stercoralis by parasitological methods, compared to two patients (3.8%) and one patient (1.9%) who were detected by ELISA using the AS and the AM antigens, respectively. S. stercoralis DNA was amplified in seven (13.5%) stool samples by qPCR. These results suggest the utility of qPCR as an alternative diagnostic tool for the diagnosis of S. stercoralis infection in immunocompromised patients, considering the possible severity of this helminthiasis in this group of patients.

    The prevalence and distribution of soil and water samples contaminated with enteroparasites of humans and animals with zoonotic potential (EHAZP) in Apucaraninha Indigenous Land (AIL), southern Brazil, was evaluated. An environmental survey was conducted to evaluate the presence of parasitic forms in peridomiciliary soil and associated variables. Soil samples were collected from 40/293 domiciles (10 domiciles per season), from November 2010 to June 2011, and evaluated by modified methods of Faust et al. and Lutz. Analyses of water from seven consumption sites were also performed. The overall prevalence of soil samples contaminated by EHAZP was 23.8 %. The most prevalent parasitic forms were cyst of Entamoeba spp. and eggs of Ascaris spp. The highest prevalence of contaminated soil samples was observed in winter (31 %). The probability map obtained with geostatistical analyses showed an average of 47 % soil contamination at a distance of approximately 140 m. The parasitological analysis of water did not detect Giardia spp. or Cryptosporidium spp. and showed that all collection points were within the standards of the Brazilian law. However, the microbiological analysis showed the presence of Escherichia coli in 6/7 sampled points. Despite the low level of contamination by EHAZP in peridomiciliar soil and the absence of pathogenic protozoa in water, the AIL soil and water (due to the presence of fecal coliforms) are potential sources of infection for the population, indicating the need for improvements in sanitation and water treatment, in addition periodic treatment of the population with antiparasitic.

    We compare the absolute visual magnitude of the majority of bright O stars in the sky as predicted from their spectral type with the absolute magnitude calculated from their apparent magnitude and the Hipparcos parallax. We find that many stars appear to be much fainter than expected, up to five magnitudes. We find no evidence for a correlation between magnitude differences and the stellar rotational velocity as suggested for OB stars by Lamers et al. (1997, A&A, 325, L25), whose small sample of stars is partly included in ours. Instead, by means of a simulation we show how these differences arise naturally from the large distances at which O stars are located, and the level of precision of the parallax measurements achieved by Hipparcos. Straightforwardly deriving a distance from the Hipparcos parallax yields reliable results for one or two O stars only. We discuss several types of bias reported in the literature in connection with parallax samples (Lutz-Kelker, Malmquist) and investigate how they affect the O star sample. In addition, we test three absolute magnitude calibrations from the literature (Schmidt-Kaler et al. 1982, Landolt-Börnstein; Howarth & Prinja 1989, ApJS, 69, 527; Vacca et al. 1996, ApJ, 460, 914) and find that they are consistent with the Hipparcos measurements. Although O stars conform nicely to the simulation, we notice that some B stars in the sample of \\citeauthor{La97} have a magnitude difference larger than expected.

    Cryophilic algae thrive in liquid water within snow and ice in alpine and polar regions worldwide. Blooms of these algae lower albedo (reflection of sunlight), thereby altering melting patterns (Kohshima, Seko & Yoshimura, 1993; Lutz et al., 2014; Thomas & Duval, 1995). Here metagenomic DNA analysis and satellite imaging were used to investigate red snow in Franz Josef Land in the Russian Arctic. Franz Josef Land red snow metagenomes confirmed that the communities are composed of the autotroph Chlamydomonas nivalis that is supporting a complex viral and heterotrophic bacterial community. Comparisons with white snow communities from other sites suggest that white snow and ice are initially colonized by fungal-dominated communities and then succeeded by the more complex C. nivalis-heterotroph red snow. Satellite image analysis showed that red snow covers up to 80% of the surface of snow and ice fields in Franz Josef Land and globally. Together these results show that C. nivalis supports a local food web that is on the rise as temperatures warm, with potential widespread impacts on alpine and polar environments worldwide.

  1. Toward an appreciation of hydrothennal-vent animals: Their environment, physiological ecology, and tissue stable isotope values

    Fisher, Charles R.

    In the last few years several comprehensive reviews of the biology of hydrothermal vent organisms and communities have been published. In this contribution I will not attempt to exhaustively review the literature, list the fauna, or the known sites, but rather present a conceptual basis for understanding the relation between the dominant metazoan "primary producers" in hydrothermal vent communities and their environment. In addition to the other chapters in this volume, interested readers are encouraged to consult the following reviews for a more detailed discussion of particular aspects of vent biology. The community ecology of hydrothermal vents is reviewed by Grassle [1986], Tunnicliffe [1991], and Lutz and Kennish [1993]. Tunnicliffe [1991] contains the most complete species lists and general site descriptions currently available. Fisher [1990] reviews the literature on chemoautotrophic symbioses and presents species lists of the hosts to chemoautotrophic symbionts known at that time. Those lists are updated in Nelson and Fisher [1995] and the physiology of the associations reviewed from a distinctly bacterial (symbiont) viewpoint. The 1992 review by Childress and Fisher takes a detailed look at the physiology of vent fauna, with a full coverage of subjects such as rate processes, blood function, and chemical composition, which are not covered in depth in the other reviews, but are of special relevance to this contribution. Uses (and abuses) of stable isotopes are discussed in several of the above reviews, and are also reviewed specifically by Conway et al. [1994], Fiala-Médioni et al. [1993], and Kennicutt et al. [1992].

Critical sanitary conditions were found in areas of incomplete urbanization, where healthy water supply sources were scarce, and draining of sewage, without previous treatment, was made directly to the water-bodies used for domestic and leisure activities, despite being Biomphalaria tenagophila snail breeding-places. Stool examinations (Kato-Katz and Lutz methods) showed prevalence of 2.9% mean intensity of 79 eggs per gram of stool and 47% of positive cases presenting intense infection. The use of snail-contaminated water for domestic purposes was considered a risk factor for infection. It is concluded that incomplete urbanization would facilitate transmission, probably enhancing the intensity of infection and that a low prevalence could hide a highly focal transmission. The relevance of these facts upon the efficiency of epidemiologic study methods and disease control planning are then discussed.

    A cross-sectional study was performed on the residents of one in every ten households in the town of Novo Airão, in the northern meso-region of the State of Amazonas, 250 kilometers from Manaus by riverboat. A family cluster sample of 89 dwellings was studied. A stool sample was requested from each of the inhabitants for examination using the Lutz sedimentation and Baermann-Moraes-Coutinho techniques, and blood was taken by venous puncture for Trypanosoma cruzi Elisa antibody testing and immunofluorescence. From a total of 316 stool samples, 87.6% had one or more parasites: Ascaris lumbricoides (35.1%), Entamoeba histolytica (29.1%), Giardia lamblia (17.4%), and other parasites with lower prevalence rates. These results were directly correlated with lack of sanitation and clean water supply. Of the 346 sera examined, 16 (4.6%) were reactive to T. cruzi antibodies, but only three showed a correlation between this result and human contact with wild triatomines, known locally as "piassava lice".

    We applied finite difference method with markers in cell technique to simulate the thermal evolution in the Danba anticline, which is located to the north of the Sichuan basin within the Songpan-Ganzi orogen. We obtained the thermal history of the Danba anticline by solving thermokenematic equations for detachment folding. With that, we calculated the corresponding fission track ages based on a chemical kinetic model proposed by Lutz and Omar and compared them with the observed ones to find out the optimal model parameters. Our results show that the Danba anticline is most likely formed by horizontal contraction along a detachment fault at depth about 15 km, corresponding to the brittle-ductile transition in the mid-crust. For the last 25 My, the horizontal shortening is estimated to be about 72 km over a cross section with a width of 180 km. The average contraction velocity of about 2.9 mm/yr but it has been accelerating in a parabolic function to about 5~6 mm/yr at the present time, which is comparable with GPS observations. Our findings suggest that a weak detachement zone should exist beneath the Danba anticline, which might be associated with crustal channel flow.

    The mosquito fauna (Culicidae) from remote northern areas of the State of Amazonas were sampled using Centers for Disease Control and Prevention, Shannon, Malaise, and Suspended traps, together with net sweeping and immature collections. One hundred and seven collections were performed in five localities along the Padauari River, State of Amazonas, Brazil, during June 2010. The 20,557 mosquitoes collected are distributed in 17 genera, representing 117 different species, of which four are new distributional records for the State of Amazonas. Furthermore, there are 10 morphospecies that may represent undescribed new taxa, eight of which are also new records for the State of Amazonas. The genus Culex had the highest number of species and the largest number of individuals. Aedes and Psorophora both represented 10% of the total sample and had the second highest number of species and individuals. The most abundant species was Culex (Melanoconion) gnomatos Sallum, Hutchings & Ferreira, followed by Aedes (Ochlerotatus) fulvus (Wiedemann), Culex (Melanoconion) vaxus Dyar, Culex (Melanoconion) portesi Senevet & Abonnenc, Psorophora (Janthinosoma) amazonica Cerqueira, Culex (Culex) mollis Dyar & Knab, Psorophora (Janthinosoma) albigenu (Peryassú), and Culex (Melanoconion) theobaldi Lutz. The epidemiological and ecological implications of mosquito species found are discussed and are compared with other mosquito inventories from the Amazon region. The results represent the most diverse standardized inventory of mosquitoes along the Padauari River, with the identification of 127 species-level taxa distributed in five localities, within two municipalities (Barcelos and Santa Isabel do Rio Negro).

    Sand flies are insects of medical and veterinary importance, because some species are able to transmit several pathogens such as Bartonella spp., Phlebovirus spp., and protozoan parasites of the genus Leishmania (Ross). They are widely distributed in the Americas, with recordings ranging from Canada to Argentina. Approximately 500 Phlebotominae species are known in the Americas, of which it is considered that at least 56 are involved in the transmission of leishmaniasis (Maroli et al. 2012). Previous studies have shown that the phlebotomine fauna in Argentina consists of 32 species distributed in 14 provinces (Quintana et al. 2012; Sábio et al. 2015; Salomón et al. 2010). Of these species, Lutzomyia longipalpis (Lutz & Neiva), Nyssomyia neivai (Pinto), Ny. whitmani (Antunes & Countinho), Cortelezzii complex [Evandromyia cortelezzii (Brèthes) - Ev. sallesi (Galvão & Coutinho)], Micropygomyia quinquefer (Dyar) and Migonemyia migonei (França) have been found with DNA of Leishmania spp. (Moya et al. 2015). Five new records of species in the province of Chaco, obtained from different projects carried out between 2001 and 2015, four of which are also new records for Argentina, are described in this article. Their importance as potential vectors and the correct determination of the sympatric species is also discussed.

    We develop and describe a Bayesian statistical analysis to solve the surface brightness equations for Cepheid distances and stellar properties. Our analysis provides a mathematically rigorous and objective solution to the problem, including immunity from Lutz-Kelker bias. We discuss the choice of priors, show the construction of the likelihood distribution, and give sampling algorithms in a Markov chain Monte Carlo approach for efficiently and completely sampling the posterior probability distribution. Our analysis averages over the probabilities associated with several models rather than attempting to pick the ``best model'' from several possible models. Using a sample of 13 Cepheids we demonstrate the method. We discuss diagnostics of the analysis and the effects of the astrophysical choices going into the model. We show that we can objectively model the order of Fourier polynomial fits to the light and velocity data. By comparison with theoretical models of Bono et al. we find that EU Tau and SZ Tau are overtone pulsators, most likely without convective overshoot. The period-radius and period-luminosity relations we obtain are shown to be compatible with those in the recent literature. Specifically, we find log()=(0.693+/-0.037)[log(P)-1.2]+(2.042+/-0.047) and v>=-(2.690+/-0.169)[log(P)-1.2]-(4.699+/-0.216).

    We present new absolute trigonometric parallaxes and proper motions for seven Pop II variable stars: the five RR Lyr stars; RZ Cep, XZ Cyg, SU Dra, RR Lyr, UV Oct; and two W Vir Pop II Cepheids; VY Pyx and kappa Pav. We obtain these results with astrometric data from Fine Guidance Sensor 1r, a white-light interferometer on Hubble Space Telescope. We measure absolute parallaxes with an average precision, 6.6%. Using these parallaxes we compute absolute magnitudes in V and K bandpasses corrected for interstellar extinction and Lutz-Kelker-Hanson bias. Considering only the RR Lyr stars, we use these absolute magnitudes to construct a K-band Leavitt Law (Period-Luminosity relation) and a Galactic Mv-[Fe/H] relation. We employ these relations to determine independent distances to the LMC and several globular clusters. For the LMC our K-band distance modulus from RR Lyr stars agrees within the errors with a previous value derived by us from Galactic Cepheids, uncorrected for metallicity. These results are based on observations made through grants GO-11211 and GO-11789 administered through the Space Telescope Science Institute, which is operated by the Association of Universities for Research in Astronomy, Inc., under NASA contract NAS5-26555.

    This study examined the frequency of Strongyloides stercoralis infection in patients with gastrointestinal cancer through parasitological and immunological tests. A total of 77 patients were evaluated, 33 with gastrointestinal cancer and 44 controls with other types of cancers. All the patients were undergoing chemotherapy and 14 (18.2%) were receiving concomitant radiotherapy. For a parasitological diagnosis, we applied the Baermann and Lutz methods. The immunological diagnosis involved the indirect fluorescence antibody test (IFAT) and enzyme linked immunosorbent assay (ELISA) to detect IgG antibodies using Strongyloides ratti antigens. The frequency of positive S. stercoralis in gastrointestinal cancer diagnosed by parasitological methods was 3 cases (9.1%), by serology it was 8 cases (24.2%). In the control group 1 case (2.3%) of S. stercoralis was diagnosed by parasitological methods and 2 cases (4.5%) by immunological tests (p<0.05). Patients with gastrointestinal cancer had a 6.7-fold greater chance of testing positive for S. stercoralis infection. Our data highlight the importance of parasitological and immunological diagnosis for S. stercoralis in patients with gastrointestinal cancer living in endemic areas of strongyloidiasis, since they have a higher risk of becoming infected with S. stercoralis than patients with other types of cancer.

    Phlebotomine sandflies are the vectors for the protozoan parasites that cause leishmaniasis. The present study investigated the species composition of sandfly fauna in the rural district of Taquaruçú, municipality of Palmas, state of Tocantins, Brazil and compared the diversity of species among intradomicile, peridomicile and forest environments during the dry and rainy seasons. Sandflies were collected using CDC light traps over the course of three months during the dry and rainy seasons. A total of 767 specimens were captured, belonging to different 32 species. The most abundant species were Micropygomyia goiana (Martins, Falcão & Silva), Sciopemyia sordellii (Shannon & Del Ponte), Evandromyia carmelinoi (Ryan Fraiha, Lainson & Shaw), Evandromyia termitophila (Martins, Falcão & Silva), Nyssomyia whitmani (Antunes & Coutinho) and Lutzomyia longipalpis (Lutz & Neiva). The highest species diversity (30) and the greatest percentage of specimens (78.3%) were obtained during the rainy season. During the dry season, the species richness and abundance were greater in domestic environments. However, during the rainy season, the forest displayed the highest species richness and the domestic environment exhibited the greatest species abundance. Several important vector species are reported in this study.

    metal-deficient stars that is currently being carried out at Hamburger Sternwarte [4]. Over a period of more than 10 years, a large collection of photographic pictures of the southern sky were obtained with the ESO 1-m Schmidt Telescope, a wide-angle telescope at the La Silla observatory in Chile that has now been decommissioned. Thanks to a large glass prism in the front of the telescope, every object in the observed sky field - stars as well as galaxies - was imaged as a small spectrum, providing a first rough idea about its type and composition. The main aim of this "Hamburg/ESO survey" (with Dieter Reimers , Associate Director of the Hamburger Sternwarte, as Principal Investigator and Lutz Wisotzki , now at Astrophysikalisches Institut Potsdam, Germany, as Project Scientist) was to find quasars (particularly active centres of galaxies), a task that was accomplished most successfully, cf. e.g., ESO PR 10/97 and ESO PR 08/00 (Report F). A very welcome by-product of this survey has been a rich harvest of very metal-poor stars . This part of the project is led by Norbert Christlieb , also from the Hamburg Observatory, and now on sabbatical leave at the Research School of Astronomy and Astrophysics of the Australian National University (Canberra, Australia). Using fast computers and advanced pattern-recognition software to analyze the photographic exposures and thus to sift through millions of registered stellar spectra, about 8000 candidates for very metal-poor stars were found. These stars are now being scrutinized spectroscopically one-by-one with many medium-sized telescopes all over the world. Confirmed candidates are then observed with the largest telescopes in the world in order to obtain very detailed spectra (of high spectral resolution), which allow the astronomers to determine their chemical composition accurately.

    An application of high energy physics instrumentation is to look for structure or different densities (materials) hidden in a matrix (tons) of material. By tracing muons produced by primary Cosmic Rays, it has been possible to generate a kind of radiographs which shows the inner structure of dense containers, monuments or mountains. In this paper I review the basics principles of such techniques with emphasis in the Sun Pyramid project, carried out by IFUNAM in collaboration with Instituto Nacioanal de Antropologia e Historia.

    The completely different conservation properties of charges associated to unbroken and broken symmetries are discussed. The impossibility of establishing a conservation law for nondegenerate Hilbert space representations in the broken case leads to a reciprocal of Coleman's theorem. The quantum statistical implication is that these charges cannot be introduced as conserved operators in the density matrix.

    An application of high energy physics instrumentation is to look for structure or different densities (materials) hidden in a matrix (tons) of material. By tracing muons produced by primary Cosmic Rays, it has been possible to generate a kind of radiographs which shows the inner structure of dense containers, monuments or mountains. In this paper I review the basics principles of such techniques with emphasis in the Sun Pyramid project, carried out by IFUNAM in collaboration with Instituto Nacioanal de Antropologia e Historia.

    In this paper the relationship between the different temperatures present in a radiative plasma is examined. In particular, the physical and operational meaning of Eckart's temperature is discussed. Following an alternative way the radiative bulk viscosity coefficient is reobtained and a more precise formulation for a maximum entropy production in the Friedmann-Robertson-Walker (FRW) background is also suggested.

    20 years ago, a new diarrheal disease was introduced in Peru and the Enteropathogens Reference Laboratory of the Instituto Nacional de Salud had an outstanding role in the isolation and rapid and timely identification of Vibrio cholerae. Cholera had not been seen before, but during the last week of January 1991 an outbreak of acute diarrhea was detected, presenting intense dehydration and some deaths. The epidemic affected, in the beginning, many locations of the peruvian coast. Some working teams of the General Office of Epidemiology and of the Instituto Nacional de Salud obtained fecal samples from patients with acute diarrhea coming from the cities of Chancay, Chimbote, Piura and some hospitals in Lima. The collected samples were transported on Cary and Blair media and processed in the National Reference Laboratory of Enteropathogens (LANARE) of the Instituto Nacional de Salud. Vibrio cholerae serogroup 01 biovar El Tor serovar Inaba was isolated from all the samples, it was sensible to tetracyclines and other antibiotics. This research confirmed the first outbreak of cholera in Peru.

The words of introduction preceding the text, written by Testa himself, provide the context of not only the historical moment the university was experiencing, just days after Rodolfo Puiggrós took office as the rector within the university's political overhaul, but also the meaning given to the project of pedagogical renovation. This project proposed redefining the relationship between the university and society, originating such projects such as the Instituto de Medicina del Trabajo (Institute of Occupational Medicine), the Instituto de la Madre y el Niño (Mother and Child Institute) and the Instituto de Patología Regional (Regional Pathology Institute) in the Faculty of Medicine; the Centro de Producción de Medicamentos de Base (the Center for Basic Drug Production) in the Faculty of Pharmacy and Biochemistry; and the Centro de Erradicación de Villas de Emergencia (Center for the Eradication of Shantytowns) in the Faculty of Architecture, among many others. Republishing these words, spoken almost 40 years ago, is a way of continuing to put into discussion the type of education and training health professionals receive with public funds.

  12. Correction and Validation of Total Ozone Data Series From An Antarctic Multichannel Filter Radiometer Solar UV Network

    Torres, C.; Redondas, A.; Cuevas, E.; Lakkala, K.; Taalas, P.

    The Antarctic Network of the MAR-Project (Measurement of Antarctic Radiance for monitoring the ozone layer) is the result of a co-operation among the Instituto Nacional de Meteorología (INM, Spain), Instituto Nacional de Técnica Aeroespacial (INTA, Spain), the Instituto Antártico Argentino - Dirección Nacional del Antártico (IAA/DNA), the Finnish Meteorological Institute (FMI), and the Centro Austral de Investigaciones Científicas (CADIC, Argentina). This network consists on three NILU-UV6 multichannel filter radiometers installed at the Argentinean Antarctic bases of Vicecomodoro Marambio and Belgrano II, and at the CADIC in Ushuaia, respectively. These instruments measure at five UV channels (305, 3120, 320, 340 and 380 nm) and PAR (400 - 700 nm). Quality control and quality assurance systems of the network give us information for irradiance correction. Quality control is based on the 2-week lamp tests performed at each station, and provides quantitative information about the stability of each instrument. Quality assurance, which is performed twice a year by the FMI, lies in inter-comparisons between the travelling reference instrument and the station instruments. These intercomparisons provide calibration coefficients for each channel. Ozone can be derived from the NILU-UV6 instruments using the 305 nm / 320 nm ratio. Ozone data series before and after irradiance correction are compared against independent ozone measurements from the TOMS, the Dobson and the UV-VIS instruments at the Ushuaia station.

    The Carlsberg Meridian Catalogues give accurate positions, proper motions and magnitudes of stars north of declination -45deg and down to 15th magnitude. They also contain observations of the solar system objects: Mars, Callisto, Saturn, Titan, Iapetus, Uranus, Neptune, Pluto, and many minor planets. Typical mean errors for an entry are 0.1arcsec in position, 3mas/yr in proper motion, and 0.05mag in magnitude. The stars observed belong to a large number of observing programmes typically dealing with the reference frame or with galactic kinematics. The Carlsberg Automatic Meridian Circle on La Palma is operated by Copenhagen University Observatory, Royal Greenwich Observatory, and Real Instituto y Observatorio de la Armada at the Observatory del Roque de los Muchachos of the Instituto de Astrofisica de Canarias. For a detailed introduction, please refer to the printed catalogue. A description of the programme may also be found in the 1993 paper by Fabricius (=1993BICDS..42....5F), from which the present description is derived. Originally the CMC7 was planned to contain only observations from 1991. The actual CMC7 comprises nearly 20 month (January 1991 to August 1992) and is thus more extensive than foreseen when a description was published in Bull.

    2010-12-01

    We report results obtained from a stratigraphic and paleomagnetic study of Plio-Pleistocene sedimentary rocks in the Borrego Badlands, E of Borrego Springs, CA. The Borrego Badlands are bordered by dextral strike slip faults of the San Jacinto fault zone (Clark fault to the NE, Coyote Creek fault to the SW), and is also cut by several NE-striking sinistral faults (linked antithetically to the Coyote Creek and Clark faults), the largest of which is the Inspiration Point fault. Our work focuses on deposits of the Palm Spring Group, including Pliocene fluvial/deltaic sandstones of the Arroyo Diablo Formation and Plio-Pleistocene lacustrine mudstones of the Borrego Formation. We collected a suite of 54 paleomagnetic sample sites from a 2500 m thick section of the Borrego Badlands (3rd Wash, Hills of the Moon Wash, and Rainbow Wash), from the upper part of the Arroyo Diablo Formation to the contact between the Borrego Formation and overlying Ocotillo Formation. This section is correlated to the upper Borrego and Ocotillo formations in Beckman Wash, located NW of here on the NW side of the Inspiration Point fault, allowing us to use the previous magnetostratigraphy of Lutz et al (2006) as a tie point for this section. Sample sites were spaced at 15 to 100 m, and 5 to 8 samples were collected from each site. Samples were thermally demagnetized using steps from 80 to 690 C, and two magnetization components were observed from 53 of the sites. A total of 49 sites had well-defined second-removed components and site mean directions that were robust (k>10). The combined mean of these 49 sites is D = 35, I = 41, α95 = 7.5. We identify 8 polarity zones in this section, ranging from near the base of the Gauss magnetochron to the upper part of the Matuyama chron, including the Mammoth, Kaena, and Olduvai subchrons. The contact between the Arroyo Diablo and Borrego formations is estimated to be ~2.9 Ma. Sediment-accumulation rates are relatively rapid and vary between 0.7 and 1

  16. HIPPARCOS subdwarfs and globular cluster ages: the distance and age of M 92

    NASA Astrophysics Data System (ADS)

    1998-01-01

    A new determination of the distance and age of the old globular cluster M 92 (NGC 6341) is obtained from a consideration of a set of more than 500 subdwarf candidates with Hipparcos parallaxes. Precise [Fe/H] values are derived for most stars using the equivalent width of the Coravel cross-correlation function. We examine at some length the biases affecting the determination of the mean luminosity of a set of subdwarfs selected by metallicity and sigma_ pi /pi Lutz-Kelker bias are found to be significant, so that in most cases considered, the resulting bias acts as a slight shift in a direction opposite to the Lutz-Kelker correction. The effect of the presence of detected (and suspected) binaries is also examined and taken into account. Our best estimate of the distance of M 92 is (m-M)_V=14.67+/- 0.08 mag, from a fit of the cluster main sequence to the 17 subdwarfs in our set with [Fe/H]<-1.8 and sigma_ pi /pi <15%. Bias and binarity corrections are included. The adoption of an alternative [Fe/H] scale causes only minor differences in this result. A more classic treatment of binaries (i.e., simply excluding the detected binaries from the sample) leads to (m-M)_V=14.74 mag. The location of the evolved field subdwarfs (along the subgiant branch) provides a strong indication that M 92 and the most metal-poor subdwarfs are coeval. The M 92 C-M diagram is confronted with up-to-date stellar evolutionary models (recent opacities and nuclear reaction rates, non-ideal equation of state, alpha -element enhancement). The agreement between theory and observations is excellent, including the position of the horizontal branch, if the models are shifted by delta (B-V)= +0.012 mag. An age of 14 Gyr is derived from the luminosities of the cluster turnoff and subgiant branch stars. A similar colour shift is found from an examination of an independent set

  17. SU-E-T-54: A New Method for Optimizing Radiation Isocenter for Linac-Based SRS

    SciTech Connect

    Hancock, S; Hyer, D; Nixon, E

    2015-06-15

    Purpose: To develop a new method to minimize deviation of linac x-ray beams from the centroid of the volumetric radiation isocenter for all combinations of gantry and table angle. Methods: A set of ball-bearing (Winston-Lutz) images was used to determine the gantry radiation isocenter as the midrange of deviation values. Deviations in the cross-plane direction were minimized by calibration of MLC leaf position offset, and by adjusting beam position steering for each energy. Special attention was also paid to matching the absolute position of isocenter across all energies by adjusting position steering in the gun-target axis. Displacement of table axis from the gantry isocenter, and recommended table axis adjustment for contemporary Elekta linacs, was also determined. Eight images were used to characterize the volumetric isocenter for the full range of gantry and table rotations available. Tabulation of deviation for each beam was used to test compliance with isocenter tolerance. Results: Four contemporary Elekta linacs were evaluated and the radius in the gun-target axis of the radiation isocenter was 0.5 to 0.7 mm. After beam steering adjustment, the radius in the cross-plane direction was typically 0.2 to 0.4 mm. Position matching between energies can be reduced to 0.28 mm. Maximum total deviation was 0.68 to 1.07 mm, depending primarily on the effect of systematic table axis wobble with rotation. Conclusion: This new method effectively facilitates minimization of deviation between beam center and target position. The test, which requires a few minutes to perform, can be easily incorporated into a routine machine QA program. A tighter radiation isocenter for contemporary Elekta linacs would require reducing the effect of gantry arm flex and/or table axis wobble that are the two main components of deviation from the designated isocenter point.

    Purpose: The aim of this study was to develop a computerized method to quantify the coincidence between portal image graticules and radiation field centers or radiation isocenter. Three types of graticules were included in this study: Megavoltage (MV) mechanical graticule, MV electronic portal imaging device digital graticule, and kilovoltage (kV) on-board imaging digital graticule. Methods: A metal ball bearing (BB) was imaged with MV and kV x-ray beams in a procedure similar to a Winston-Lutz test. The radiation fields, graticules, and BB were localized in eight portal images using Hough transform-based computer algorithms. The center of the BB served as a static reference point in the 3D space so that the distances between the graticule centers and the radiation field centers were calculated. The radiation isocenter was determined from the radiation field centers at different gantry angles. Results: Misalignments of MV and kV portal imaging graticules varied with the gantry or x-ray source angle as a result of mechanical imperfections of the linear accelerator and its imaging system. While the three graticules in this study were aligned to the radiation field centers and the radiation isocenter within 2.0 mm, misalignments of 1.5-2.0 mm were found at certain gantry angles. These misalignments were highly reproducible with the gantry rotation. Conclusions: A simple method was developed to quantify the alignments of portal image graticules directly against the radiation field centers or the radiation isocenter. The advantage of this method is that it does not require the BB to be placed exactly at the radiation isocenter through a precalibrated surrogating device such as room lasers or light field crosshairs. The present method is useful for radiation therapy modalities that require high-precision portal imaging such as image-guided stereotactic radiotherapy.

  19. Maxadilan-simile expression in Nyssomyia neivai, a sandfly vector in an endemic region of Brazil, and its immunogenicity in patients with American tegumentary leishmaniasis

    BACKGROUND Maxadilan (Max) is a salivary component in the sandfly Lutzomyia longipalpis (Lutz & Neiva 1912), a vector of visceral leishmaniasis. Max has a powerful vasodilatory effect and is a candidate vaccine that has been tested in experimental leishmaniasis. Nyssomyia neivai (Pinto 1926) is a vector of the pathogen responsible for American tegumentary leishmaniasis (ATL) in Brazil. OBJECTIVE We searched for Max expression in Ny. neivai and for antibodies against Max in ATL patients. METHODS cDNA and protein were extracted from the cephalic segment, including salivary glands, of Ny. neivai and analysed by polymerase chain reaction, DNA sequencing, and blotting assays. The results were compared with data obtained from Lu. longipalpis samples. We quantified antibodies against Max in serum samples from 41 patients with ATL (31 and 10 with the cutaneous and mucocutaneous forms, respectively) and 63 controls from the endemic northeastern region of São Paulo state, using enzyme-linked immunosorbent assay. FINDINGS Recognition of a Max-simile peptide by specific antibodies confirmed expression of a Max sequence in Ny. neivai (GenBank EF601123.1). Compared to controls, patients with ATL presented higher levels of antibodies against Max (p = 0.004); 24.4% of the patients with ATL and 3.2% of the controls presented anti-Max levels above the cutoff index (p = 0.014). The anti-Max levels were not associated with the specific clinical form of ATL, leishmanin skin test response, absence or presence of amastigotes in histopathologic exam, results of indirect immunofluorescence testing for leishmaniasis, or duration of cutaneous form disease. MAIN CONCLUSION High serum anti-Max levels did not protect patients against ATL, but confirmed previous natural exposure to Ny. neivai bites in this ATL endemic region. PMID:28177045

    In the state of Rio Grande do Norte in northeast Brazil, cases of visceral leishmaniasis (VL) occur mainly in the periurban areas of the city of Natal. Lutzomyia longipalpis Lutz & Neiva 1912 (Diptera: Psychodidae), a vector of Leishmania chagasi (Protozoa: Trypanosomatidae) to humans, is found throughout the state. Flora and fauna influence the distribution of sand fly species, whose horizontal or vertical stratification can be used as a parameter for identifying potential vectors, considering the presence of vertebrate hosts in the area. The purpose of this study was to obtain information about the vertical stratification of phlebotomine sand flies in an endemic area of leishmaniasis in Rio Grande do Norte, and associate it with the presence of other animals in the peridomiciliary environment as well as to analyze, under laboratory conditions, aspects of L. longipalpis reproduction in wild females. The sand flies were captured with light traps hung at different heights in species of Atlantic Forest trees and in a peridomiciliary environment in animal shelters. The traps were placed between 17:30 and 6:00 of the following day, in a peridomiciliary and extradomiciliary area of a forest fragment in both dry and rainy months. In the extradomiciliary environment, the traps were installed at 1, 3 and 5 m above the ground. The biological cycle of L. longipalpis was followed from the eggs of 200 wild females. Specimens of L. lenti, L. walkeri, and L. migonei were captured. The comparison and statistical analysis showed that L. longipalpis is more abundant at a height of 3 m and L. evandroi at 1 m. In the animal shelters (chickens, horses, and armadillos), we captured mainly specimens of L. longipalpis and L. evandroi. The duration of the biological cycle of L. longipalpis was approximately 38 days at a temperature of 28 degrees C.
