    Cessy, 7 September 2010 Subject: Thanks for the evening of solidarity in favour of the victims of the Haiti earthquake organised by the CERN Fitness Club. The "HAÏTI-ECOLES" Association wishes to thank everyone who took part in the event. The donation of 2080 CHF paid onto the Association's account will be transferred in its entirety to our partners in Haiti who are in charge of running the Verrettes and La Chapelle schools. They are responsible for meeting the needs of families affected by the earthquake: buying food, helping to pay the rent on small houses, payment of school fees when school starts again in September. The number of children enrolled in the schools has risen from 2300 to 2500 following the huge influx of families who fled Port au Prince in the aftermath of the earthquake. The Association's principal role is helping with the schooling of disadvantaged children in Verrettes and La Chapelle and keeping the school canteens running to make sure that the children ...

    Full Text Available Objective. To determine if there is an unrecognized problem of congenital rubella syndrome (CRS in Haiti, a country without a national rubella immunization program. Methods. During March 2001 and June 2001, screening physicals were conducted on approximately 80 orphans at three orphanages in Haiti that accept disabled children. Children were classified as probable CRS cases based on established clinical criteria. Photo documentation of findings was obtained whenever possible. Results. Six children met the criteria for probable CRS. Using data from surrounding Caribbean countries and from the United States of America prior to rubella immunization, we estimated that there are between 163 and 440 new cases of CRS per year in Haiti. Conclusions. CRS exists in Haiti, but its presence is generally unrecognized. A national rubella immunization policy should be considered.

    Frankel, Arthur; Harmsen, Stephen; Mueller, Charles; Calais, Eric; Haase, Jennifer

    2011-01-01

    We have produced probabilistic seismic hazard maps of Haiti for peak ground acceleration and response spectral accelerations that include the hazard from the major crustal faults, subduction zones, and background earthquakes. The hazard from the Enriquillo-Plantain Garden, Septentrional, and Matheux-Neiba fault zones was estimated using fault slip rates determined from GPS measurements. The hazard from the subduction zones along the northern and southeastern coasts of Hispaniola was calculated from slip rates derived from GPS data and the overall plate motion. Hazard maps were made for a firm-rock site condition and for a grid of shallow shear-wave velocities estimated from topographic slope. The maps show substantial hazard throughout Haiti, with the highest hazard in Haiti along the Enriquillo-Plantain Garden and Septentrional fault zones. The Matheux-Neiba Fault exhibits high hazard in the maps for 2% probability of exceedance in 50 years, although its slip rate is poorly constrained.

    RIT1 belongs to the RAS family of small GTPases. Germline and somatic RIT1 mutations have been identified in Noonan syndrome (NS) and cancer, respectively. By using heterologous expression systems and purified recombinant proteins, we identified the p21-activated kinase 1 (PAK1) as novel direct effector of RIT1. We found RIT1 also to directly interact with the RHO GTPases CDC42 and RAC1, both of which are crucial regulators of actin dynamics upstream of PAK1. These interactions are independent of the guanine nucleotide bound to RIT1. Disease-causing RIT1 mutations enhance protein-protein interaction between RIT1 and PAK1, CDC42 or RAC1 and uncouple complex formation from serum and growth factors. We show that the RIT1-PAK1 complex regulates cytoskeletal rearrangements as expression of wild-type RIT1 and its mutant forms resulted in dissolution of stress fibers and reduction of mature paxillin-containing focal adhesions in COS7 cells. This effect was prevented by co-expression of RIT1 with dominant-negative CDC42 or RAC1 and kinase-dead PAK1. By using a transwell migration assay, we show that RIT1 wildtype and the disease-associated variants enhance cell motility. Our work demonstrates a new function for RIT1 in controlling actin dynamics via acting in a signaling module containing PAK1 and RAC1/CDC42, and highlights defects in cell adhesion and migration as possible disease mechanism underlying NS.

The Metar bracelet for the feeder tubes, the REC robot for the heat exchanger and the RIT robot for the Delayed Neutron system just to name a few. This paper discusses with the successful deployment of the Camera Probe Positioning robot for Visual Inspection of the sample lines of the delayed neutron system of CANDU power plants. This RIT robot has three possible configurations (Face, Cabinet and LRG configurations) and has remained a prototype version although it has been used over the years in many outage inspection campaigns since 1997. The main advantages of using this robot are: the significant reduction in radiation exposure, the high quality of the data collected and the archiving of inspection data for further analysis and reports. In 2007, Gentilly-2 (G-2), decided to industrialize the LRG configuration of the RIT robot and to designate it the standard tool for the inspection of the Delayed Neutron System. An improved RIT-LRG robot, along with its control box and command station was developed. The software had to be rewritten requiring an ergonomics analysis of user tasks, work station and interface display. These issues included both physical and cognitive requirements aspects. The two principal topics of this paper will be on the Inspection Robot Technology developed and highlights of the 2008 outage inspection campaign. (author)

    Noonan syndrome is the most frequent of the congenital group of malformation syndromes caused by germline mutations that encode components of the RAS/MAPK pathway, termed RASopathies, one of the most frequent congenital genetic disorders in the clinical practice. Recently RIT1 mutations have been reported in patients with Noonan syndrome. A 7 years-old girl with a clinical diagnosis of Noonan syndrome, and with a hypertrophic cardiomyopathy included in her clinical manifestations, where a de novo heterozygous, probably pathogenic, novel mutation in RIT1, c.295T>C (p.Phe99Leu), has been identified. RIT1 shares homology with other RAS proteins and the expression of mutant alleles demonstrates a gain-of-function effect supporting a causative role in Noonan syndrome pathogenesis. Data suggest that the frequency of RIT1 mutations can be estimated as 3-5% in Noonan syndrome patients. These cases compared with Noonan patients harboring mutations in other genes are characterized by high frequency of prenatal abnormalities and hypertrophic cardiomyopathy, and lower frequencies of short stature and pectus abnormalities. We emphasize the importance of the novel identified genes in order to be included in the diagnostic panels.

  17. Haiti. Educating factory workers.

    Science.gov (United States)

    Hughes, H

    1990-04-01

    There are approximately 50,000 workers employed in the light assembly industry in Haiti. About 70% are women, the majority of whom are aged between 25 and 34 years, and are either single or in a nonpermanent relationship with the father of their children. Many live and work in appalling conditions, surviving on very low wages to support several children and an extended family. The acquired immunodeficiency syndrome (AIDS) is now a visible problem in many factories. In October 1988, the Center for the Promotion of Women Workers (Centre de Promotion des Femmes Ouvriers/CPFO) launched a pilot AIDS education program for factory women. The Center, based in a large industrial zone near the airport, runs a health clinic and courses in literacy, communications skills, health promotion and family planning. The new AIDS program allowed CPFO staff to gain entry into factories for the 1st time. Other courses were held outside working hours and outside factory premises. Staff contacted manages by telephone to arrange a meeting to discuss AIDS and to ask permission to hold educational "round tables" with workers. Of 18 managers in the factories approached over a 12-month period, only 2 refused entry to CPFO staff. Almost all managers reported they had registered between 2 and 5 deaths from AIDS among their employees over the past couple of years. A total of 85 educational sessions, each lasting about 2 hours, were held within 28 different factories, community or labor organizations reaching 3063 workers (male and female). In each session, the presentation was carried out by 2 CPFO trained monitors and included a slide show, flip charts, and the video "Met ko," originally produced for Haitian immigrants in New York. The most important aspect of the program was the training of 38 volunteer factory-based health promoters. These promoters attended the round table sessions, where they facilitated discussion and distributed condoms and were subsequently available for counseling co

    As one of the preliminary research projects of Chinese ELT, 30m RIT--Ring Interferometric Telescope are being simulated and tentatively designed by Yunnan Astronomical Observatory, CAS. The simulations of 30m RIT are mainly included as follows: PSF transform and the image quality at limited photons mode, active control mode of the primary ring mirror, the phasing mode of 30m segmented ring mirror, the turbulent atmosphere and adaptive optics etc. This paper also introduces some tentative design results of 30m RIT, such as the optical design, the conceptual design of the enclosure. The astronomical experiments at seeing limited case and diffraction limited case are introduced in this paper too. A ring aperture mask was put on the entrance pupil of a one meter telescope, real astronomical objects were observed by this "ring telescope" and reconstructed by high resolution imaging techniques such as speckle masking, iterative shift and add methods. The diffraction imaging ability and the full u-v coverage property of a ring aperture were proved by these astronomical experiments.

  1. Radioiodine-treatment (RIT) of functional thyroidal autonomy

    International Nuclear Information System (INIS)

    Meller, J.; Sahlmann, C.O.; Becker, W.

    2002-01-01

    Since 1942, therapy with radioiodine (RIT) has gained a major role in the treatment of benign thyroid disorders, notably hyperthyroidism caused by Graves' disease or toxic multinodular goitre (thyroid autonomy). In iodine deficient areas thyroid autonomy accounts for 40-50% of all cases with hyperthyroidism. RIT has become a cost-effective first-line procedure in autonomy-patients with latent or overt hyperthyroidism, especially in the absence of a large goitre, after thyroid surgery and in elderly patients with associated conditions who carry a high intra- or perioperative risk. Decisions concerning the definitive treatment of thyroid autonomy should take into account previous episodes of hyperthyroidism, objective parameters of risk stratification in euthyroid patients as well as concomitant diseases and the probability of iodine exposure in the future. In Central Europe the majority of investigators prefer to estimate the therapeutic activity individually by a radioiodine test. TCTUs (global 99m-Tc-pertechnetate thyroid uptake under suppression) - based dose concepts have been proven to be highly effective in the elimination of autonomy and carry a low (< 10%) risk of postradioiodtherapeutic hypothyroidism. Radioiodine therapy for autonomy has been found to be both effective and safe and without major early or late side effects. The most frequent complication is hypothyroidism requiring lifelong follow-up. (author)

  2. Modeling near-road air quality using a computational fluid dynamics model, CFD-VIT-RIT.

    Wang, Y Jason; Zhang, K Max

    2009-10-15

    It is well recognized that dilution is an important mechanism governing the near-road air pollutant concentrations. In this paper, we aim to advance our understanding of turbulent mixing mechanisms on and near roadways using computation fluid dynamics. Turbulent mixing mechanisms can be classified into three categories according to their origins: vehicle-induced turbulence (VIT), road-induced turbulence (RIT), and atmospheric boundary layer turbulence. RIT includes the turbulence generated by road embankment, road surface thermal effects, and roadside structures. Both VIT and RIT are affected by the roadway designs. We incorporate the detailed treatment of VIT and RIT into the CFD (namely CFD-VIT-RIT) and apply the model in simulating the spatial gradients of carbon monoxide near two major highways with different traffic mix and roadway configurations. The modeling results are compared to the field measurements and those from CALINE4 and CFD without considering VIT and RIT. We demonstrate that the incorporation of VIT and RIT considerably improves the modeling predictions, especially on vertical gradients and seasonal variations of carbon monoxide. Our study implies that roadway design can significantly influence the near-road air pollution. Thus we recommend that mitigating near-road air pollution through roadway designs be considered in the air quality and transportation management In addition, thanks to the rigorous representation of turbulent mixing mechanisms, CFD-VIT-RIT can become valuable tools in the roadway designs process.

    An automation target device intended for isotope production on the internal beam of the RITs cyclotron is decribed. The target device comprises the following main units: target head, vacuum lock, charging device, transport system for bringing the target for charging; mechanism of target discharge transport device, control interlocking and signalling control system of target radiation power. The automation target device permits radioisotope production on the cyclotron in commercial scales with automation substitution of irradiated targets. The time of substitution of one of six targets makes up only 5 min. The time of charging a new group of targets to the charge device - 60 min. Contact of the personnel with irradiated targets is practically excluded and the necessity of entering the cyclotron room for maintenance of the plant is reduced to the minimum [ru

  6. Haiti, insecurity, and the politics of asylum.

    Science.gov (United States)

    James, Erica Caple

    2011-09-01

    In this article, I seek to show how states of insecurity provoked by ongoing social, economic, and political ruptures in Haiti can disorder individual subjectivity and generate the flight of individuals seeking asylum within and across borders. Nongovernmental actors working in Haiti and with Haitians in the diaspora frequently managed the long-term psychosocial effects of insecurity. Their interventions can range from repressive to compassionate and influence the formation of identity and the embodied experiences of trauma for vulnerable Haitians. The case of a young Haitian refugee who was repatriated to Haiti from the United States in the 1990s demonstrates how insecurity is both an existential state reflecting the disordering of embodied experience, as well as a collective sociopolitical condition the effects of which cannot be managed or contained within national borders. The case is emblematic of the plight of thousands of Haitians affected by the January 12, 2010, earthquake.

  7. Astronomical Polarimetry with the RIT Polarization Imaging Camera

    2018-06-01

    In the last decade, imaging polarimeters based on micropolarizer arrays have been developed for use in terrestrial remote sensing and metrology applications. Micropolarizer-based sensors are dramatically smaller and more mechanically robust than other polarimeters with similar spectral response and snapshot capability. To determine the suitability of these new polarimeters for astronomical applications, we developed the RIT Polarization Imaging Camera to investigate the performance of these devices, with a special attention to the low signal-to-noise regime. We characterized the device performance in the lab, by determining the relative throughput, efficiency, and orientation of every pixel, as a function of wavelength. Using the resulting pixel response model, we developed demodulation procedures for aperture photometry and imaging polarimetry observing modes. We found that, using the current calibration, RITPIC is capable of detecting polarization signals as small as ∼0.3%. The relative ease of data collection, calibration, and analysis provided by these sensors suggest than they may become an important tool for a number of astronomical targets.

  11. Nursing and nursing education in Haiti.

    Garfield, Richard M; Berryman, Elizabeth

    2012-01-01

    Haiti has long had the largest proportion of people living in poverty and the highest mortality level of any country in the Americas. On January 12, 2010, the most powerful earthquake to hit Haiti in 200 years struck. Before the earthquake, half of all Haitians lacked any access to modern medical care services. Health care professionals in Haiti number around one-fourth of the world average and about one-tenth the ratio present in North America. The establishment of new primary care services in a country where half of the people had no access to modern health care prior to the earthquake requires advanced practice roles for nurses and midwives. With a high burden of infectious, parasitic, and nutritional conditions, Haiti especially needs mid-level community health workers and nurses who can train and supervise them for public health programs. As in many other developing countries, organized nursing lacks many of the management and planning skills needed to move its agenda forward. The public schools prepare 3-year diploma graduates. These programs have upgraded the curriculum little in decades and have mainly trained for hospital service. Primary care, public health program management, and patient education had often not been stressed. Specializations in midwifery and HIV care exist, while only informal programs of specialization exist in administration, surgery, and pediatrics. An advanced practice role, nonetheless, is not yet well established. Nursing has much to contribute to the recovery of Haiti and the revitalization if its health system. Professional nurses are needed in clinics and hospitals throughout the country to care for patients, including thousands in need of rehabilitation and mental health services. Haitian nursing colleagues in North America have key roles in strengthening their profession. Ways of supporting our Haitian colleagues are detailed. Copyright © 2012 Elsevier Inc.

    2016-03-01

    RASopathies are a clinically heterogeneous group of conditions caused by mutations in 1 of 16 proteins in the RAS-mitogen activated protein kinase (RAS-MAPK) pathway. Recently, mutations in RIT1 were identified as a novel cause for Noonan syndrome. Here we provide additional functional evidence for a causal role of RIT1 mutations and expand the associated phenotypic spectrum. We identified two de novo missense variants p.Met90Ile and p.Ala57Gly. Both variants resulted in increased MEK-ERK signaling compared to wild-type, underscoring gain-of-function as the primary functional mechanism. Introduction of p.Met90Ile and p.Ala57Gly into zebrafish embryos reproduced not only aspects of the human phenotype but also revealed abnormalities of eye development, emphasizing the importance of RIT1 for spatial and temporal organization of the growing organism. In addition, we observed severe lymphedema of the lower extremity and genitalia in one patient. We provide additional evidence for a causal relationship between pathogenic mutations in RIT1, increased RAS-MAPK/MEK-ERK signaling and the clinical phenotype. The mutant RIT1 protein may possess reduced GTPase activity or a diminished ability to interact with cellular GTPase activating proteins; however the precise mechanism remains unknown. The phenotypic spectrum is likely to expand and includes lymphedema of the lower extremities in addition to nuchal hygroma. © 2015 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    A time-projection chamber (TPC) called the SAMURAI Pion-Reconstruction and Ion-Tracker (SπRIT) has recently been constructed at Michigan State University as part of an international effort to constrain the symmetry-energy term in the nuclear Equation of State (EoS). The SπRIT TPC will be used in conjunction with the SAMURAI spectrometer at the Radioactive Isotope Beam Factory (RIBF) at RIKEN to measure yield ratios for pions and other light isospin multiplets produced in central collisions of neutron-rich heavy ions, such as 132 Sn+ 124 Sn. The SπRIT TPC can function both as a TPC detector and as an active target. It has a vertical drift length of 50 cm, parallel to the magnetic field. Gas multiplication is achieved through the use of a multi-wire anode plane. Image charges, produced in the 12096 pads, are read out with the recently developed Generic Electronics for TPCs

    Full Text Available Abstract Background We determined direct medical costs, overhead costs, societal costs, and personnel requirements for the provision of antiretroviral therapy (ART to patients with AIDS in Haiti. Methods We examined data from 218 treatment-naïve adults who were consecutively initiated on ART at the GHESKIO Center in Port-au-Prince, Haiti between December 23, 2003 and May 20, 2004 and calculated costs and personnel requirements for the first year of ART. Results The mean total cost of treatment per patient was $US 982 including $US 846 in direct costs, $US 114 for overhead, and $US 22 for societal costs. The direct cost per patient included generic ART medications $US 355, lab tests $US 130, nutrition $US 117, hospitalizations $US 62, pre-ART evaluation $US 58, labor $US 51, non-ART medications $US 39, outside referrals $US 31, and telephone cards for patient retention $US 3. Higher treatment costs were associated with hospitalization, change in ART regimen, TB treatment, and survival for one year. We estimate that 1.5 doctors and 2.5 nurses are required to treat 1000 patients in the first year after initiating ART. Conclusion Initial ART treatment in Haiti costs approximately $US 1,000 per patient per year. With generic first-line antiretroviral drugs, only 36% of the cost is for medications. Patients who change regimens are significantly more expensive to treat, highlighting the need for less-expensive second-line drugs. There may be sufficient health care personnel to treat all HIV-infected patients in urban areas of Haiti, but not in rural areas. New models of HIV care are needed for rural areas using assistant medical officers and community health workers.

  1. Documentation for Initial Seismic Hazard Maps for Haiti

    2010-01-01

    In response to the urgent need for earthquake-hazard information after the tragic disaster caused by the moment magnitude (M) 7.0 January 12, 2010, earthquake, we have constructed initial probabilistic seismic hazard maps for Haiti. These maps are based on the current information we have on fault slip rates and historical and instrumental seismicity. These initial maps will be revised and improved as more data become available. In the short term, more extensive logic trees will be developed to better capture the uncertainty in key parameters. In the longer term, we will incorporate new information on fault parameters and previous large earthquakes obtained from geologic fieldwork. These seismic hazard maps are important for the management of the current crisis and the development of building codes and standards for the rebuilding effort. The boundary between the Caribbean and North American Plates in the Hispaniola region is a complex zone of deformation. The highly oblique ~20 mm/yr convergence between the two plates (DeMets and others, 2000) is partitioned between subduction zones off of the northern and southeastern coasts of Hispaniola and strike-slip faults that transect the northern and southern portions of the island. There are also thrust faults within the island that reflect the compressional component of motion caused by the geometry of the plate boundary. We follow the general methodology developed for the 1996 U.S. national seismic hazard maps and also as implemented in the 2002 and 2008 updates. This procedure consists of adding the seismic hazard calculated from crustal faults, subduction zones, and spatially smoothed seismicity for shallow earthquakes and Wadati-Benioff-zone earthquakes. Each one of these source classes will be described below. The lack of information on faults in Haiti requires many assumptions to be made. These assumptions will need to be revisited and reevaluated as more fieldwork and research are accomplished. We made two sets of

  2. Sustainable Community Sanitation for a Rural Hospital in Haiti

    Directory of Open Access Journals (Sweden)

    2012-12-01

    Full Text Available A fully sustainable sanitation system was developed for a rural hospital in Haiti. The system operates by converting human waste into biogas and fertilizer without using external energy. It is a hybrid anaerobic/aerobic system that maximizes methane production while producing quality compost. The system first separates liquid and solid human waste at the source to control carbon to nitrogen ratio and moisture content to facilitate enhanced biodegradation. It will then degrade human waste through anaerobic digestion and capture the methane gas for on-site use as a heating fuel. For anaerobic decomposition and methane harvesting a bioreactor with two-stage batch process was designed. Finally, partially degraded human waste is extracted from the bioreactor with two-stage batch process and applied to land farming type aerobic composter to produce fertilizer. The proposed system is optimized in design by considering local conditions such as waste composition, waste generation, reaction temperature, residence time, construction materials, and current practice. It is above ground with low maintenance requirements.

    Casualties are estimated for the 12 January 2010 earthquake in Haiti using various reports calibrated by observed building damage states from satellite imagery and reconnaissance reports on the ground. By investigating various damage reports, casualty estimates and burial figures, for a one year period from 12 January 2010 until 12 January 2011, there is also strong evidence that the official government figures of 316 000 total dead and missing, reported to have been caused by the earthquake, are significantly overestimated. The authors have examined damage and casualties report to arrive at their estimation that the median death toll is less than half of this value (±137 000). The authors show through a study of historical earthquake death tolls, that overestimates of earthquake death tolls occur in many cases, and is not unique to Haiti. As death toll is one of the key elements for determining the amount of aid and reconstruction funds that will be mobilized, scientific means to estimate death tolls should be applied. Studies of international aid in recent natural disasters reveal that large distributions of aid which do not match the respective needs may cause oversupply of help, aggravate corruption and social disruption rather than reduce them, and lead to distrust within the donor community.

    RITS (Radiographic Integrated Test Stand) is an induction voltage adder designed by Sandia and PSD to provide 16-MV, 150-kA electron beams and other capabilities. Previous publications have reported on tests of a single pulse forming line and adder cell, including initial results of the effects of various degrees of non-uniform injection of current into the adder bore on magnetic insulation and power flow in the downstream MITL. Now RITS-3 has been constructed, consisting of three pfls driven by a common intermediate store; three induction cells, one driven by each pfl; a three-stage, 4-MV, 150-kA vacuum voltage adder; and an output MITL and diode. Here we report on (1) simulations of the three-stage adder using the MRC 3-D particle-in-cell code LSP that address the effects of injected current non-uniformities on magnetic insulation and power-flow both upstream and downstream in a multi-cell adder; (2) experimental results compared with simulations; and (3) initial performance of the RITS-3 pulse power

    Noonan syndrome is a heterogeneous autosomal dominant disorder caused by mutations in at least eight genes involved in the RAS/MAPK signaling pathway. Recently, RIT1 (Ras-like without CAAX 1) has been shown to be involved in the pathogenesis of some patients. We report a series of 44 patients from 30 pedigrees (including nine multiplex families) with mutations in RIT1. These patients display a typical Noonan gestalt and facial phenotype. Among the probands, 8.7% showed postnatal growth retardation, 90% had congenital heart defects, 36% had hypertrophic cardiomyopathy (a lower incidence compared with previous report), 50% displayed speech delay and 52% had learning difficulties, but only 22% required special education. None had major skin anomalies. One child died perinatally of juvenile myelomonocytic leukemia. Compared with the canonical Noonan phenotype linked to PTPN11 mutations, patients with RIT1 mutations appear to be less severely growth retarded and more frequently affected by cardiomyopathy. Based on our experience, we estimate that RIT1 could be the cause of 5% of Noonan syndrome patients. Because mutations found constitutionally in Noonan syndrome are also found in several tumors in adulthood, we evaluated the potential contribution of RIT1 to leukemogenesis in Noonan syndrome. We screened 192 pediatric cases of acute lymphoblastic leukemias (96 B-ALL and 96 T-ALL) and 110 cases of juvenile myelomonocytic leukemias (JMML), but detected no variation in these tumoral samples, suggesting that Noonan patients with germline RIT1 mutations are not at high risk to developing JMML or ALL, and that RIT1 has at most a marginal role in these sporadic malignancies.

    Full Text Available Background. Preventing mother-to-child transmission of HIV relies on engagement in care during the prenatal, peripartum, and postpartum periods. Under PMTCT Option B, pregnant women with elevated CD4 counts are provided with antiretroviral prophylaxis until cessation of breastfeeding. Methods. Retrospective analysis of retention in care among HIV-infected pregnant women in Haiti was performed. Logistic regression was used to identify risk factors associated with loss to follow-up (LFU defined as no medical visit for at least 6 months and Kaplan-Meier curves were created to show LFU timing. Results. Women in the cohort had 463 pregnancies between 2009 and 2012 with retention rates of 80% at delivery, 67% at one year, and 59% at 2 years. Among those who were LFU, the highest risk period was during pregnancy (60% or shortly afterwards (24.4% by 12 months. Never starting on antiretroviral therapy (aRR 2.29, 95% CI 1.4–3.8 was associated with loss to follow-up. Conclusions. Loss to follow-up during and after pregnancy was common in HIV-infected women in Haiti under PMTCT Option B. Since sociodemographic factors and distance from home to facility did not predict LFU, future work should elicit and address barriers to retention at the initial prenatal care visit in all women. Better tracking systems to capture engagement in care in the wider network are needed.

    2016-03-01

    This article explores the effects of the 2010 Haiti earthquake on women's reproductive health, using geocoded data from the 2005 and 2012 Haiti Demographic and Health Surveys. We use geographic variation in the destructiveness of the earthquake to conduct a difference-in-difference analysis. Results indicate that heightened earthquake intensity reduced use of injectables-the most widely used modern contraceptive method in Haiti-and increased current pregnancy and current unwanted pregnancy. Analysis of impact pathways suggests that severe earthquake intensity significantly increased women's unmet need for family planning and reduced their access to condoms. The earthquake also affected other factors that influence reproductive health, including women's ability to negotiate condom use in their partnerships. Our findings highlight how disruptions to health care services following a natural disaster can have negative consequences for women's reproductive health. © 2016 The Population Council, Inc.

    Cholera reappeared in Haiti in October, 2010 after decades of absence. Cases were first detected in Artibonite region and in the ensuing months the disease spread to every department in the country. The rate of increase in the number of cases at the start of epidemics provides valuable information about the basic reproductive number (). Quantitative analysis of such data gives useful information for planning and evaluating disease control interventions, including vaccination. Using a mathematical model, we fitted data on the cumulative number of reported hospitalized cholera cases in Haiti. varied by department, ranging from 1.06 to 2.63. At a national level, 46% vaccination coverage would result in an () cholera vaccines in endemic and non-endemic regions, our results suggest that moderate cholera vaccine coverage would be an important element of disease control in Haiti.

    Mobile health (mHealth) technology can play a critical role in improving disaster victim tracking, triage, patient care, facility management, and theater-wide decision-making. To date, no disaster mHealth application provides responders with adequate capabilities to function in an austere environment. The Operational Medicine Institute (OMI) conducted a qualitative trial of a modified version of the off-the-shelf application iChart at the Fond Parisien Disaster Rescue Camp during the large-scale response to the January 12, 2010 earthquake in Haiti. The iChart mHealth system created a patient log of 617 unique entries used by on-the-ground medical providers and field hospital administrators to facilitate provider triage, improve provider handoffs, and track vulnerable populations such as unaccompanied minors, pregnant women, traumatic orthopedic injuries and specified infectious diseases. The trial demonstrated that even a non-disaster specific application with significant programmatic limitations was an improvement over existing patient tracking and facility management systems. A unified electronic medical record and patient tracking system would add significant value to first responder capabilities in the disaster response setting.

    The effects of heart failure (HF) severity on risk of inappropriate implantable cardioverter-defibrillator (ICD) therapy have not been thoroughly investigated. We aimed to study the association between HF severity and inappropriate ICD therapy in MADIT-RIT. MADIT-RIT randomized 1,500 patients to three ICD programming arms: conventional (Arm A), high-rate cut-off (Arm B: ≥200 beats/min), and delayed therapy (Arm C: 60-second delay for ≥170 beats/min). We evaluated the association between New York Heart Association (NYHA) class III (n = 256) versus class I-II (n = 251) and inappropriate ICD therapy in Arm A patients with ICD-only and cardiac resynchronization therapy with defibrillator (CRT-D). We additionally assessed benefit of novel ICD programming in Arms B and C versus Arm A by NYHA classification. In Arm A, the risk of inappropriate therapy was significantly higher in those with NYHA III versus NYHA I-II for both ICD (hazard ratio [HR] = 2.55, confidence interval [CI]: 1.51-4.30, P programming significantly reduced inappropriate therapy in patients with both NYHA III (Arm B vs Arm A: HR = 0.08, P programming with high-rate cut-off or delayed detection reduces inappropriate ICD therapies in both mild and moderate HF. © 2017 Wiley Periodicals, Inc.

    Sandia National Laboratories is investigating and developing high-dose, high-brightness flash radiographic sources. We are in the process of designing; fabricating and conducting engineering tests on the next-generation magnetically immersed electron diodes. These diodes employ unique, large-bore (80-110 mm), high-field (28-45 T), cryogenically-cooled solenoid magnets to help produce an intense electron beam from a needle-like cathode 'immersed' in the strong Bz field of the magnet. The diode designs and status of the engineering development are described. Later this year we plan to conduct experiments with these sources on the new Radiographic Integrated Test Stand (RITS), now in operation at Sandia. In its present three-stage configuration, RITS provides a 4-MV, 150-kA, 70-ns pulse to the diode. Fully three-dimensional particle in cell LSP code simulations are used to investigate relevant physics issues and the expected radiographic performance (spot size and dose) of this system.

    Noonan syndrome is a well-known genetic condition associating congenital heart defects, short stature, and distinctive facial features. Pulmonary valve stenosis and hypertrophic cardiomyopathy are the most frequent cardiac abnormalities, the latter being associated with a higher mortality. Here we report for the first time, a case of congenital left main coronary artery atresia in a Noonan syndrome associated with RIT1 variant, leading to unrescued sudden death. This case-report supports the already-suspected severity of the RIT1-related Noonan syndrome compared to average Noonan syndrome, and should encourage clinicians to be very cautious with these patients.

Ritüel, devlet ya da din kurumları oluşmadan önceki zamanlardan başlayarak insan hayatının önemli bir parçası olmuştur. Erken dönemlerde yalnızca kutsal olanla ilişkilendirilen ritüeller, ilerleyen süreçte ortak bir değerler dizgesinin oluşumunun getirdiği milletleşmeye paralel biçimde ayırt edici unsurlar kazanarak sistemleşmiştir. Milletleşmenin getirdiği birliktelik duygusu tarihsel arka planı olan ritüellerin yaşamasına olanak verirken yeni sosyal ve siyasal kabuller, aynı misyonu kendi amaçlarına uyarlamak üzere yeni törenler ve bu törenlerde uygulanan ritüeller oluşturmuştur. Aynı kültür dairesinden olmakla birlikte farklı siyasal görüşlere mensup kitlelerin belirli zamanlar içerisinde farkındalıklarını göstermek, ortak bir öğe üzerinde birleşmeyi sağlamak gibi amaçlarla var ettikleri tören ve ritüeller siyasalı oluşturanların ilkesel birlikteliği süresince devam etmiş ve etmektedir.Osmanlı İmparatorluğu sonrasında kurulan Türkiye Cumhuriyeti de doğal olarak yukarıda temel unsurları belirtilen genel çerçeveye uygun bir şekilde gerek resmi gerekse gayrı resmi tören ve bağlı ritüellerin gerçekleştirildiği bir politik ve sosyal yapıya sahiptir.

    RAS GTPases mediate a wide variety of cellular functions, including cell proliferation, survival, and differentiation. Recent studies have revealed that germline mutations and mosaicism for classical RAS mutations, including those in HRAS, KRAS, and NRAS, cause a wide spectrum of genetic disorders. These include Noonan syndrome and related disorders (RAS/mitogen-activated protein kinase [RAS/MAPK] pathway syndromes, or RASopathies), nevus sebaceous, and Schimmelpenning syndrome. In the present study, we identified a total of nine missense, nonsynonymous mutations in RIT1, encoding a member of the RAS subfamily, in 17 of 180 individuals (9%) with Noonan syndrome or a related condition but with no detectable mutations in known Noonan-related genes. Clinical manifestations in the RIT1-mutation-positive individuals are consistent with those of Noonan syndrome, which is characterized by distinctive facial features, short stature, and congenital heart defects. Seventy percent of mutation-positive individuals presented with hypertrophic cardiomyopathy; this frequency is high relative to the overall 20% incidence in individuals with Noonan syndrome. Luciferase assays in NIH 3T3 cells showed that five RIT1 alterations identified in children with Noonan syndrome enhanced ELK1 transactivation. The introduction of mRNAs of mutant RIT1 into 1-cell-stage zebrafish embryos was found to result in a significant increase of embryos with craniofacial abnormalities, incomplete looping, a hypoplastic chamber in the heart, and an elongated yolk sac. These results demonstrate that gain-of-function mutations in RIT1 cause Noonan syndrome and show a similar biological effect to mutations in other RASopathy-related genes.

    The immersed-B{sub z} diode is being developed as a high-brightness, flash x-ray radiography source. This diode is a foil-less electron-beam diode with a long, thin, needle-like cathode inserted into the bore of a solenoid. The solenoidal magnetic field guides the electron beam emitted from the cathode to the anode while maintaining a small beam radius. The electron beam strikes a thin, high-atomic-number anode and produces bremsstrahlung. We report on an extensive series of experiments where an immersed-B{sub z} diode was fielded on the RITS-3 pulsed power accelerator, a 3-cell inductive voltage generator that produced peak voltages between 4 and 5 MV, {approx}140 kA of total current, and power pulse widths of {approx}50 ns. The diode is a high impedance device that, for these parameters, nominally conducts {approx}30 kA of electron beam current. Diode operating characteristics are presented and two broadly characterized operating regimes are identified: a nominal operating regime where the total diode current is characterized as classically bipolar and an anomalous impedance collapse regime where the total diode current is in excess of the bipolar limit and up to the full accelerator current. The operating regimes are approximately separated by cathode diameters greater than {approx}3 mm for the nominal regime and less than {approx} 3 mm for the anomalous impedance collapse regime. This report represents a compilation of data taken on RITS-3. Results from key parameter variations are presented in the main body of the report and include cathode diameter, anode-cathode gap, and anode material. Results from supporting parameter variations are presented in the appendices and include magnetic field strength, prepulse, pressure and accelerator variations.

    The first phase of the clinical trial using the humanized monoclonal antibody h-R3 labeled with {sup 188} Re, for radioimmunotherapy (RIT) of brain tumors began in the Republic of Cuba in 2002. This monoclonal antibody was obtained in the country and it is required to evaluate its toxicity, biodistribution and internal radiation dosimetry. Five groups of three patients of each one with an administered activity from 0.37 GBq to 1.1 GBq, are considered. The aim of this work is to assess workers doses and public doses for this research and to compare projected doses with the first results related to the radiological surveillance. The contribution to the total effective dose and equivalent dose in extremities are calculated with the code Microshield version 4.0 by each activity level, operation and total quantity of patients. We take into account radioactive decay of {sup 188} Re and consider that only a person made all of the operations during this study. It is demonstrated that individual doses are acceptable and lower than world average effective annual dose of natural radiation background (2.4 mSv), because for the operations of more risk are used individual protection means. Nevertheless, it is identified that nurses are the most exposed. The projected maximum equivalent dose to hands is about 4 mSv and it belongs to the neurosurgeon. Radiological surveillance is performed to verify our calculations. Five workers and public (four individuals) are monitoring for each patient with direct reading dosimeters DOSICARD and TLD for extremities. For the first seven patients results are obtained. The conservative assumptions in the dose assessment and the compliance with established safety procedures determine that the registered doses are lower than those were projected. RIT with 188 Re for high-grade astrocytomas is a safety practice from radiation protection point of view. There is not a reference of a similar study in Latin America. (author)

    To investigate the improved clearance effect of avidin (Av) and streptavidin-gal (SA - gal) for blood radiolabeled biotinylated antibody in pre-targeting radio-immuno therapy (RIT) of colon carcinoma xenograft models. Biotinylated antibody radiolabeled with 131 I was injected into the nude mice bearing the colon carcinoma via the tail vein. 24 h later, in 2 test groups, SA-gal or Av at a 10 - fold molar excess of antibody was intraperitoneally injected into the animals whereas no any chase agents were given to the control animals. Animals were killed for biodistribution study at 30h after 131 I-labelled biotinylated antibody administration. Results showed that Av and SA-gal took the effect of chase very fast. At 6h after injection, the blood level of radioactivity decreased very fast. The tumor/blood ratios of control group, Av chase group, SA-gal chase group were 0.42, 2.09, 5.23 respectively, P < 0.05 and P < 0.01 for the latter two groups as compared other control groups. Compared with Av, SA-gal showed better chase effect, its T/B ratios was 5.23, significantly higher than 2.09 of Av (P < 0.01). In the tissue biodistributions, relatively high non-specific radioactivity uptakes in non-liver organs were seen in Av chase group. Utilized in pre-targeting RIT, both Av and SA-gal could make the blood level of radioactivity decrease quickly and considerably improves tumor T/NT ratios. The chase effect of SA-gal was superior to that of avidin

    In spite of the strength of gravitational focres between celestial bodies, gravitational capture is not a simple concept. The principles of conservation of linear momentum and of conservation of angular momentum, always impose severe constraints, while conservation of energy and the vital distinction between dissipative and non-dissipative systems allows one to rule out capture in a wide variety of cases. In complex systems especially those without dissipation, long dwell time is a more significant concept than permanent capture. (author)

    Two stories from Haiti are considered from three different perspectives. The first story is about a boy named Joseph Alvyns, whose mother died from cholera in 2011. His story is told in a short film titled Baseball in the time of Cholera. The second story is about Mme. Yolande Marie Nazaire, who was the Director of the Haiti National School of Nursing in Port-au-Prince on the morning of January 12, 2010, when an earthquake killed 90 students and faculty. The three perspectives discussed here are: (a) Critical Reflective in health professional education as used by the University of California at San Francisco (UCSF) School of Medicine; (b) The Capacities of Stories, which is part of a socio-narratology methodology; and(c) Story Theory with implications for global health nursing.

    Damage to the inferior and fragile water and sanitation infrastructure of Haiti after Hurricane Matthew has created an urgent public health emergency in terms of likelihood of cholera occurring in the human population. Using satellite-derived data on precipitation, gridded air temperature, and hurricane path and with information on water and sanitation (WASH) infrastructure, we tracked changing environmental conditions conducive for growth of pathogenic vibrios. Based on these data, we predicted and validated the likelihood of cholera cases occurring past hurricane. The risk of cholera in the southwestern part of Haiti remained relatively high since November 2016 to the present. Findings of this study provide a contemporary process for monitoring ground conditions that can guide public health intervention to control cholera in human population by providing access to vaccines, safe WASH facilities. Assuming current social and behavioral patterns remain constant, it is recommended that WASH infrastructure should be improved and considered a priority especially before 2017 rainy season.

    Health care providers frequently struggle to develop wise applications of theoretical knowledge. As a nurse studying traditional approaches in ethics while simultaneously volunteering in Haiti, I wrestled with the notion of justice in the midst of radical material inequities. Paul Farmer, physician and anthropologist, provides an analytic perspective for health care providers who work in poor and underserved countries by expanding the liberation theology of the 1970s to include social applications. Analyzing my past experiences in Haiti using Farmer's methodology provided insight into my successes and failures and prompted me to search for personal and professional reasons to provide care for the poor in the future. This type of reflection is essential for health care providers who work with the underserved, regardless of their religion or the country in which they work.

    2010-01-01

    With the recent earthquake in Haiti, it is most befitting to discuss my travel to this poor country more than a decade ago. The travel was a mission that examined the health status and the education of residents in the capital city of Port- au-Prince. After close observation, it seems that the health and educational status then, today and since the tragedy, is basically the same with less, if any, possible improvement. This article examines the present state of health and education of the Haitian people, in the wake of its recent tragedy. Although, the people were very poor in economics, they were rich in culture and exhibited polite mannerisms that made me feel overly welcomed in their homes and to the few resources they had to offer It appears that in past years, this country was and still is noted as the poorest country in the Americas, however, it is not the poorest country in the Western Hemisphere. On many occasions, it has been publicly and widely reported that Haiti experienced political violence throughout its history. The government of Haiti is known for corruption. It also appears that an earthquake the magnitude of 7.0 would not have easily destroyed so many of its infrastructure and people, if in the past, the surrounding countries, including the United States, would have assisted in providing this country with safer and stronger foundations for buildings and especially shelter for the residents and the many visitors who were the true victims. Despite the repressive regime, Haiti's location, history and culture were very attractive to tourists in the 1960s and 1970s. Visitors returned home with memorable artifacts that included cave paintings, wood statues (figurines) and hand made jewelry.

  7. Availability, prices and affordability of essential medicines in Haiti.

    Haiti is the poorest country in the Western Hemisphere and faces numerous challenges, including inadequate medication access for its residents. The objective of this study was to determine the availability, prices, and affordability of essential medicines in Haiti and compare these findings to other countries. We conducted a cross-sectional nationwide survey in 2011 of availability and consumer prices of 60 essential medicines in Haiti using a standardized methodology developed by the World Health Organization and Health Action International. The survey was conducted in 163 medicine outlets in four health care sectors (public, retail, nonprofit and mixed sectors). Medicine prices were expressed as ratios relative to the International Reference Price. Affordability was calculated by comparing the costs of treatment for common conditions with the salary of the lowest paid government worker and was compared to available data from four Latin American countries. For generic medicines, the availability in public, retail, nonprofit and mixed sectors was 20%, 37%, 24% and 23% of medications, respectively. Most of the available medicines were priced higher than the International Reference Price. The lowest paid government worker would need 2.5 days' wages to treat an adult respiratory infection with generic medicines from the public sector. For treatment of common conditions with originator brands (OB) purchased from a retail pharmacy, costs were between 1.4 (anaerobic bacterial infection) and 13.7 (hyperlipidemia) days' wages, respectively. Treatment of pediatric bacterial infections with the OB of ceftriaxone from a retail pharmacy would cost 24.6 days' wages. Prices in Bolivia, Colombia, Mexico and Nicaragua were frequently lower for comparable medications. The availability of essential medicines was low and prices varied widely across all four sectors. Over 75% of Haitians live on less than US$ 2.00 /day; therefore, most medication regimens are largely unaffordable

  9. On the probability of extinction of the Haiti cholera epidemic

    Nearly 3 years after its appearance in Haiti, cholera has already exacted more than 8,200 deaths and 670,000 reported cases and it is feared to become endemic. However, no clear evidence of a stable environmental reservoir of pathogenic Vibrio cholerae, the infective agent of the disease, has emerged so far, suggesting that the transmission cycle of the disease is being maintained by bacteria freshly shed by infected individuals. Thus in principle cholera could possibly be eradicated from Haiti. Here, we develop a framework for the estimation of the probability of extinction of the epidemic based on current epidemiological dynamics and health-care practice. Cholera spreading is modelled by an individual-based spatially-explicit stochastic model that accounts for the dynamics of susceptible, infected and recovered individuals hosted in different local communities connected through hydrologic and human mobility networks. Our results indicate that the probability that the epidemic goes extinct before the end of 2016 is of the order of 1%. This low probability of extinction highlights the need for more targeted and effective interventions to possibly stop cholera in Haiti.

The information is then entered onto computer manually, thus making the process a long and arduous one. With the development of the Haiti Commodity Tracker mobile app, we are able to make this commodity price data recording process more efficient. Officials may use this information for making inferences about the difference in commodity prices and for food distribution during critical time after natural disasters. This information can also be utilized by governments and aid agencies on their food assistance programs. Agronomists record the item prices from several sample sites in a marketplace and compare those results from other markets across the region. Due to limited connectivity in rural areas, data is first saved to the phone's database and then retransmitted to a central server via SMS messaging. The mobile app is currently being field tested by an international NGO providing agricultural aid and support in rural Haiti.

    Fasciola hepatica, the aetiological agent of fascioliasis in the Caribbean region, occurs throughout the major islands of the Greater Antilles and in localised zones on two islands (Martinique and Saint Lucia) of the Lesser Antilles. However, apart from Puerto Rico, information regarding human fascioliasis in islands of the Caribbean is out of date or unavailable, or even nonexistent as in Haiti. The authors conducted a retrospective, cross-sectional serological survey in Port-au-Prince using a Western blotting test (LDBIO Diagnostics) on human fascioliasis in Haiti. A total of 216 serum samples obtained from apparently healthy adults were tested. The frequency of antibodies in serum samples of the study population was 6.5% (14/216). The immunodominant bands recognised in Western blots were 27-28 kDa (100%), 42 kDa (64%), 60 kDa, and 8-9 kDa (28%). This is the first survey to reveal a relatively low proportion of asymptomatic F. hepatica-infected humans in Haiti.

    Full Text Available Eastern part of the Republic of Croatia as a tourist destination is not fully valorized yet, despite its natural values and rich cultural heritage. Stronger contribution to touristic development could be ensured by Kopački rit Nature Park as potentially great tourist attractor. Its flora and fauna attract people for educational and tourist reasons. Tourism in nature parks has certain limitations due to primary goals which are protection and preservation of nature together with sustainable management of nature resources and ensuring an undisturbed course of natural processes. The aim of this research is to emphasize importance of marketing tools implementation in process of tourist activities development. Through application of marketing techniques and especially nonprofit marketing, primary goals related to nature protection can be harmonized with development of self-financing through tourism activities. Research was conducted by using case study methodology. Relevant persons for the topic were interviewed and from collected information SWOT analysis was made which may be used for policy suggestions in process of creation adequate tourist products and services together with ensuring quality education for visitors and minimizing visitors influence on natural resources.

    Together with Petrovaradin wetland positioned on the opposite banks of the river Danube, named in Serbian 'Koviljsko-Petrovaradinski rit' (Kovilj-Petrovaradin wetland), this area has been proposed for the registration of wetland areas of international significance according to the Ramsar Convention. The Kovilj-Petrovaradin wetland is being registered as the Natural treasure of special significance and is being classified into I category of protection as the Special Nature Reserve. The protection and conservation of this wetland area is in agreement with Action Plan of protection of rivers and accompanied wetlands in the frame of Paneuropean Strategy for the protection of biological and landscape diversity, accepted at the Strasburg Conference (1995). Being of such importance, this project should contribute to the raising of awareness of this special wetland value as well as to the importance of protection, conservation and improvement of this kind of ecosystems in general. Also, the objectives and results should contribute to the achieving of the wise use of this special wetland and of natural resources as a whole. (author)

    There have been estimates that over 150,000 Haitian children are living in servitude. Child domestic servants who perform unpaid labor are referred to as "restavèks." Restavèks are often stigmatized, prohibited from attending school, and isolated from family placing them at higher risk for experiencing violence. In the absence of national data on the experiences of restavèks in Haiti, the study objective was to describe the sociodemographic characteristics of restavèks in Haiti and to assess their experiences of violence in childhood. The Violence Against Children Survey was a nationally representative, cross-sectional household survey of 13-24year olds (n=2916) conducted May-June 2012 in Haiti. A stratified three-stage cluster design was used to sample households and camps containing persons displaced by the 2010 earthquake. Respondents were interviewed to assess lifetime prevalence of physical, emotional, and sexual violence occurring before age 18. Chi-squared tests were used to assess the association between having been a restavèk and experiencing violence in childhood. In this study 17.4% of females and 12.2% of males reported having been restavèks before age 18. Restavèks were more likely to have worked in childhood, have never attended school, and to have come from a household that did not have enough money for food in childhood. Females who had been restavèks in childhood had higher odds of reporting childhood physical (OR 2.04 [1.40-2.97]); emotional (OR 2.41 [1.80-3.23]); and sexual violence (OR 1.86 [95% CI 1.34-2.58]) compared to females who had never been restavèks. Similarly, males who had ever been restavèks in childhood had significantly increased odds of emotional violence (OR 3.06 [1.99-4.70]) and sexual violence (OR 1.85 [1.12-3.07]) compared to males who had never been restavèks, but there was no difference in childhood physical violence. This study demonstrates that child domestic servants in Haiti experience higher rates of

    Noonan syndrome (NS) is a genetic condition presenting with typical facies, cardiac defects, short stature, variable developmental deficit, cryptorchidism, skeletal, and other abnormalities. Germline mutations in genes involved in the RAS/MAPK signaling have been discovered to underlie NS. Recently, missense mutations in RIT1 have been reported as causative for individuals with clinical signs of NS. We report on a 2.5-year-old boy with NS phenotype with a novel heterozygous change in the RIT1 gene. The patient was born prematurely from pregnancy monitored for polyhydramnios. At 7 months of age, non-immune neutropenia and splenomegaly have been observed. During the severe pneumonia at 10 months, significant progression of hepatosplenomegaly, leukopenia with monocytosis (15-29 %), and thrombocytopenia occurred. Bone marrow evaluation showed myeloid hyperplasia and monocytosis, suggestive of myeloproliferative syndrome. Clinical phenotype (facial dysmorphism, soft hair, short neck, broad chest, widely spaced nipples, mild pectus carinatum, deep palmar creases, unilateral cryptorchidism), and moderate pulmonary valve stenosis with mild psychomotor delay were indicative of NS. DNA analysis identified a de novo heterozygous variant c.69A >T, p.(Lys23Asn) in exon 2 of the RIT1 gene, presumed to be causative. We present a patient with a clinical suspicion of NS carrying a novel substitution in RIT1 and hematologic findings not being observed in RIT1 positive patients to date. Thus, the case broadens variability of hematologic symptoms in RIT1 positive NS individuals. • Noonan syndrome is a common genetically heterogeneous disorder of autosomal dominant inheritance characterized by craniofacial dysmorphism, short stature, congenital heart defects, variable cognitive deficit, and other anomalies. What is new: • We report on a 2.5-year-old male patient with clinical signs of NS and hematologic abnormalities, in whom a novel heterozygous substitution in RIT1 with probable

    Ovarian peritoneal carcinomatosis is a pathology for which effective cures are currently lacking. New research protocols seek to eradicate residual micrometastases following cytoreductive surgery by using hyperthermic intraperitoneal chemotherapy (HIPEC) or radioimmunotherapy (RIT). This study aims to first develop alpha-RIT using an anti-CD138 mAb radiolabeled with an alpha-emitter, bismuth-213 ((213)Bi-B-B4) and HIPEC in a nude mouse model and second to compare and combine these techniques. A murine model of postoperative ovarian peritoneal carcinomatosis was established. A pilot group of six mice received an intraperitoneal injection of luciferase-tagged SHIN-3 cells and bioluminescence was measured every day. Cytoreductive surgery was performed at day 14 (n = 4) and 29 (n = 2). Because the residual bioluminescence signal measured after surgery was equivalent to that obtained 3 days after the graft, HIPEC or alpha-RIT treatments were applied 3 days after the graft. Ten mice were treated by HIPEC with cisplatine (37.5 mg/mL), 11 with 7.4 MBq of (213)Bi-B-B4, seven with 11.1 MBq of (213)Bi-B-B4, and 10 mice were treated with the combined therapy (HIPEC + 7.4 MBq of (213)Bi-B-B4). Eleven mice received no treatment. Bioluminescence imaging and survival were assessed. Alpha-RIT 7.4 MBq and 11.1 MBq significantly improved survival (p = 0.0303 and p = 0.0070, respectively), whereas HIPEC and HIPEC + alpha-RIT treatments did not significantly ameliorate survival as compared to the control group. Survival was significantly increased by alpha-RIT treatment in mice with peritoneal carcinomatosis of ovarian origin; however, HIPEC alone or in combination with alpha-RIT had no significant effect.

    Tungiasis is endemic in poverty-stricken communities of South and Central America, Africa, Asia, and the Caribbean. This ectoparasitosis, caused by the female sand flea Tunga penetrans, is associated with considerable longterm morbidity in severely affected patients, including toe deformation and limited mobility. In Haiti, tungiasis is poorly documented but is known to occur. This study is the first formal investigation of tungiasis in Haiti. A total of 383 patients in four regions (Belle Fontaine, Vallue, Savanette, Cerca Carvajal) were examined and interviewed to determine disease prevalence, demographics and clinical presentation, and tungiasis-related behaviors. Prevalences of tungiasis ranged from 10.6 to 81.8% across the four regions. The overall prevalence of tungiasis in the patients examined was 31.1%. Of the affected patients, 63% were male and 37% were female, 37% were aged 0-10 years, and 100% reported pain and pruritus. Lesions occurred on the feet in 93.3% and on the hands in 22.7% of affected patients. The most common complications observed were chronic inflammation (54.2%) and hyperkeratosis (48.2%). This study establishes tungiasis as endemic in four regions of Haiti and reveals disease characteristics similar to those reported previously, suggesting that there are common factors underlying this disease in various regions, which are likely to be poverty-related. These findings emphasize the need to acknowledge tungiasis as a clinically relevant public health issue in order to decrease the frequency of tungiasis-related morbidity in endemic areas. © 2014 The International Society of Dermatology.

    This report details current epidemiologic information on peripartum cardiomyopathy in 1 district of Haiti and represents the initial report of an ongoing investigation that addresses potential etiologic and prognostic factors. Another goal is to alert the medical community of what appears to be a high-incidence area. A detailed peripartum cardiomyopathy registry has been implemented to include a review of case records from 1994 to 2000 and subsequently to identify new cases from February 1, 2000, to July 1, 2001. The Hospital Albert Schweitzer District of Haiti is a 600-square mile area with approximately 258,000 population served by a hospital, an associated clinic, and outlying health centers. There are approximately 7740 live births annually. This report details epidemiologic information on the HAS District peripartum cardiomyopathy patients including incidence, mortality rate, complications, and prognostic factors. There were 47 confirmed patients (retrospective cohort, 20 patients; prospective cohort, 27 patients), which was approximately 1 case per 400 live births (compared with an incidence of 1 case per 3000 to 4000 live births in the United States). There were 4 deaths (14% of 29 patients with follow-up), and 7 complications (pulmonary embolism, 1 case; hemiplegia, 1 case; subsequent deterioration of heart function, 5 cases). The prognosis for subsequent pregnancy was 4 of 5 cases (80%) of recurrent congestive heart failure. Peripartum cardiomyopathy appears to be relatively common in the Hospital Albert Schweitzer District of Haiti. A core group of patients is identified for ongoing epidemiologic and immunohematologic investigation of risk factors and potential etiologic factors.

    Full Text Available Purpose: Little is known about the epidemiology of breast cancer in developing countries, and Haiti has perhaps the least data of any country in the Western Hemisphere. Methods: We conducted a retrospective review of all patients enrolled in an ongoing breast cancer treatment program in Port-au-Prince, Haiti, from July 1, 2013, through June 30, 2017. Data were drawn from each patient's electronic medical record, paper chart, and biopsy results. Results: The records of 525 women with breast cancer were reviewed for this study. The median age at presentation was 49 years (n = 507. The risk factors observed were as follows: postmenopausal, 50.8% (n = 354; nulliparity, 15.7% (n = 338; hormonal contraception use, 35.0% (n = 309; never breastfed, 20.6% (n = 316; family history of any cancer, 22.0% (n = 295; overweight, 51.5% (n = 332; and smoking, 5.0% (n = 338. Of all those staged, 83.9% (n = 447 of the patients presented with stage III/IV disease and more than half delayed care for > 12 months after first noticing a breast mass. For the subset of tumors for which estrogen receptor (ER; n = 245 and human epidermal growth factor receptor 2 (HER2; n = 179 status was available, the prevalence of ER-positive tumors was 51.8%, of HER2-positive tumors was 19.6%, and of triple-negative tumors was 38.5%. The 12-month mortality rate (n = 425 was 18.4% overall and 27.5% for those who presented with stage IV disease. Median survival was not reached. Conclusion: Breast cancer in Haiti presents at an early age and advanced stage. Triple-negative, ER-negative, and high-grade tumors are common. Delays in seeking care and incomplete treatment likely contribute to the high mortality rate; however, as in black women in the United States, the distribution of tumor types may contribute to disparate outcomes.

    Despite improvement, maternal mortality in Haiti remains high at 359/100,000 live births. Improving access to high quality antenatal and postnatal care has been shown to reduce maternal mortality and improve newborn outcomes. Little is known regarding the quality and uptake of antenatal and postnatal care among Haitian women. Exit interviews were conducted with all pregnant and postpartum women seeking care from large health facilities (n = 10) in the Nord and Nord-Est department and communes of St. Marc, Verrettes, and Petite Rivière in Haiti over the study period (March-April 2015; 3-4 days/facility). Standard questions related to demographics, previous pregnancies, current pregnancy, and services/satisfaction during the visit were asked. Total number of antenatal visits were abstracted from charts of recently delivered women (n = 1141). Provider knowledge assessments were completed by antenatal and postnatal care providers (n = 39). Frequencies were calculated for descriptive variables and multivariable logistic regression was used to explore predictors of receiving 5 out of 10 counseling messages among pregnant women. Among 894 pregnant women seeking antenatal care, most reported receiving standard clinical service components during their visit (97% were weighed, 80% had fetal heart tones checked), however fewer reported receiving recommended counseling messages (44% counselled on danger signs, 33% on postpartum family planning). Far fewer women were seeking postnatal care (n = 63) and similar service patterns were reported. Forty-three percent of pregnant women report receiving at least 5 out of 10 counseling messages. Pregnant women on a repeat visit and women with greater educational attainment had greater odds of reporting having received 5 out of 10 counseling messages (2 nd visit: adjusted odds ratio [aOR] =1.70, 95% confidence interval [CI]: 1.09-2.66; 5+ visit: aOR = 5.44, 95% CI: 2.91-10.16; elementary school certificate: a

    2015-04-01

    Container-based sanitation (CBS) - in which wastes are captured in sealable containers that are then transported to treatment facilities - is an alternative sanitation option in urban areas where on-site sanitation and sewerage are infeasible. This paper presents the results of a pilot household CBS service in Cap Haitien, Haiti. We quantify the excreta generated weekly in a dense urban slum, (1) the proportion safely removed via container-based public and household toilets, and the costs associated with these systems. The CBS service yielded an approximately 3.5-fold decrease in the unmanaged share of faeces produced, and nearly eliminated the reported use of open defecation and "flying toilets" among service recipients. The costs of this pilot small-scale service were higher than those of large-scale waterborne sewerage, but economies of scale have the potential to reduce CBS costs over time. The paper concludes with a discussion of planning and policy implications of incorporating CBS into the menu of sanitation options for rapidly growing cities.

    Haiti and the Dominican Republic, which share the island of Hispaniola, are the last locations in the Caribbean where malaria still persists. Malaria is an important public health concern in Haiti with 17,094 reported cases in 2014. Further, on January 12, 2010, a record earthquake devastated densely populated areas in Haiti including many healthcare and laboratory facilities. Weakened infrastructure provided fertile reservoirs for uncontrolled transmission of infectious pathogens. This situation results in unique challenges for malaria epidemiology and elimination efforts. To help Haiti achieve its malaria elimination goals by year 2020, the Laboratoire National de Santé Publique and Henry Ford Health System, in close collaboration with the Direction d'Épidémiologie, de Laboratoire et de Recherches and the Programme National de Contrôle de la Malaria, hosted a scientific meeting on "Elimination Strategies for Malaria in Haiti" on January 29-30, 2015 at the National Laboratory in Port-au-Prince, Haiti. The meeting brought together laboratory personnel, researchers, clinicians, academics, public health professionals, and other stakeholders to discuss main stakes and perspectives on malaria elimination. Several themes and recommendations emerged during discussions at this meeting. First, more information and research on malaria transmission in Haiti are needed including information from active surveillance of cases and vectors. Second, many healthcare personnel need additional training and critical resources on how to properly identify malaria cases so as to improve accurate and timely case reporting. Third, it is necessary to continue studies genotyping strains of Plasmodium falciparum in different sites with active transmission to evaluate for drug resistance and impacts on health. Fourth, elimination strategies outlined in this report will continue to incorporate use of primaquine in addition to chloroquine and active surveillance of cases. Elimination of

  12. FPGA-based Upgrade to RITS-6 Control System, Designed with EMP Considerations

    International Nuclear Information System (INIS)

    Anderson, Harold D.; Williams, John T.

    2009-01-01

    The existing control system for the RITS-6, a 20-MA 3-MV pulsed-power accelerator located at Sandia National Laboratories, was built as a system of analog switches because the operators needed to be close enough to the machine to hear pulsed-power breakdowns, yet the electromagnetic pulse (EMP) emitted would disable any processor-based solutions. The resulting system requires operators to activate and deactivate a series of 110-V relays manually in a complex order. The machine is sensitive to both the order of operation and the time taken between steps. A mistake in either case would cause a misfire and possible machine damage. Based on these constraints, a field-programmable gate array (FPGA) was chosen as the core of a proposed upgrade to the control system. An FPGA is a series of logic elements connected during programming. Based on their connections, the elements can mimic primitive logic elements, a process called synthesis. The circuit is static; all paths exist simultaneously and do not depend on a processor. This should make it less sensitive to EMP. By shielding it and using good electromagnetic interference-reduction practices, it should continue to operate well in the electrically noisy environment. The FPGA has two advantages over the existing system. In manual operation mode, the synthesized logic gates keep the operators in sequence. In addition, a clock signal and synthesized countdown circuit provides an automated sequence, with adjustable delays, for quickly executing the time-critical portions of charging and firing. The FPGA is modeled as a set of states, each state being a unique set of values for the output signals.

    Full Text Available - La fiesta de Qoyllur Rit'i, que se presenta todos los años para el tiempo de Corpus Christi en un valle aislado cerca del Cusco, es todavía dominada por creencias indígenas. En este trabajo se intenta demostrar que la fiesta es de origen precolombino y que originalmente se celebraba el tránsito de un año al próximo, del mundo pasado al presente. Este concepto de tránsito es luego examinado en el contexto de las ideas del espacio y tiempo, tanto de los Incas como de la actualidad andina. The fiesta of Qoyllur Rit'i, held every year at Corpus Christi in an isolated valley near Cusco, is still dominated by indigenous beliefs. In this paper it is suggested that the fiesta is actually pre-Columbian in origin and that it was originally intended as a celebration of the transition form one year to the next, from the past world to the present. This concept of transition is then placed within the context of both Inca and present-day Andean ideas of time and space.

    Haiti has the worst malnutrition rate in the Western hemisphere. In October 2010, a cholera epidemic erupted and spread rapidly throughout the country, straining Haiti's already fragile health infrastructure across all levels of care. This study reviews data from an outpatient therapeutic feeding program (OTP) for acute childhood malnutrition at a clinic in rural Haiti with a focus on the effect of the 2010 cholera epidemic on program operations. A retrospective chart review was conducted for the complete set of patients who were enrolled in the OTP from its inception in March 2009 through January 2014. A total of 187 charts were retrieved representing 176 unique patients, of whom 5 were currently enrolled in care. At admission, 96 (51.3%) met criteria for severe acute malnutrition, 88 (47.1%) met criteria for moderate acute malnutrition, and 3 (1.6%) did not meet criteria for acute malnutrition. Of the 182 completed charts, 119 (65.4%) reached their target weight (≥-1 weight-for-height z-score) by discharge (ie, were "cured"), 43 (23.6%) defaulted, 11 (6.0%) were discharged prematurely, 8 (4.4%) died, and 1 (0.5%) was hospitalized. A total of 11 patients (6.3%) who were initially admitted relapsed after discharge and were later readmitted. Data from 170 complete records (93.4%) were included in a multivariate logistic regression. Severe (vs moderate) acute malnutrition was negatively associated with likelihood of being cured when controlling for other patient- and care-related factors (OR = 0.261, P = .002). Average cholera burden was negatively correlated with likelihood of OTP treatment cure when controlling for patient- and care-related variables (OR = 0.859, P = .002) but was insignificant when controlling for year. Results from the study have been used to inform a restructuring of the clinic's acute malnutrition program toward a more community-centered model of management, the context and implications of which are discussed in relation to the existing

    CD20 has been used as target molecule for low-dose as well as high-dose, myeloablative RIT of B-cell NHL. MCL is an especially aggressive, prognostically unfavorable form of B-cell NHL. The aim of this study was to investigate whether high-dose, myeloablative RIT with the 131 I-labeled chimeric anti-CD20 antibody C2B8 (rituxan, Mabthera, Roche) may be therapeutically more effective than conventional low-dose therapy in MCL. A total of twelve patients with chemorefractory or relapsed mantle cell lymphoma were studied so far (all of them having relapsed after high-dose chemotherapy, seven of them combined with 12 Gy TBI). A diagnostic-dosimetric study was performed with 10 mCi of 131 I-C2B8 at a protein dose of 2.5 mg/kg. In case of splenic pooling, the protein dose was increased until a more 'favorable' biodistribution was obtained. Therapy was performed with conventional (30-75 mCi; n=4) or myeloablative activities (261-515 mCi; n=8) of 131 I-C2B8 at the previously optimized protein dose, aiming at whole-body doses of ≤ 0.8 Gy (for low-dose RIT) or lung doses of ≤ 27 Gy (for high-dose RIT). Clinical follow-up was obtained for up to 42 months. Overall, in 11 patients the 2.5 mg/kg protein dose was used, whereas in one patient with marked splenomegaly, 10 mg/kg were necessary to overcome the splenic antigenic sink. In the high-dose patients, non-hematologic toxicity was restricted to mild to moderate nausea, fever, transient bilirubin or liver enzyme elevations. Despite thyroid blocking, 6/8 high-dose (in contrast to 0/4 low-dose) patients developed hypothyroidism, requiring thyroxine substitution at 6-18 months after RIT. The response rate in the low-dose arm was only 1(PR)/4, whereas 7/8 high-dose patients experienced complete and the remainder a partial remission. 6 high-dose patients are still in CR (one of them relapsed locally at 3 months, one systemically at 26 months after RIT), and 7 are still alive for up to 42+ months. In contrast to low-dose therapy

    Haiti remains the poorest country in the Americas and one of the poorest in the world. Children in Haiti face many health concerns, some of which were exacerbated by the 2010 earthquake. This systematic review summarizes published research conducted since the 2010 earthquake, focusing on health outcomes for children in Haiti, including physical, psychological, and socioeconomic well-being. A literature search was conducted identifying articles published from January 2010 through May 2016 related to pediatric health outcomes in Haiti. Two reviewers screened articles independently. Included research articles described at least one physical health, psychological health, or socioeconomic outcome among children less than 18 years of age in Haiti since the January 2010 earthquake. Fifty-eight full-length research articles were reviewed, covering infectious diseases (non-cholera [N=12] and cholera [N=7]), nutrition (N=11), traumatic injuries (N=11), mental health (N=9), anemia (N=4), abuse and violence (N=5), and other topics (N=3). Many children were injured in the 2010 earthquake, and care of their injuries is described in the literature. Infectious diseases were a significant cause of morbidity and mortality among children following the earthquake, with cholera being one of the most important etiologies. The literature also revealed that large numbers of children in Haiti have significant symptoms of posttraumatic stress disorder (PTSD), peri-traumatic stress, depression, and anxiety, and that food insecurity and malnutrition continue to be important issues. Future health programs in Haiti should focus on provision of clean water, sanitation, and other measures to prevent infectious diseases. Mental health programming and services for children also appear to be greatly needed, and food insecurity/malnutrition must be addressed if children are to lead healthy, productive lives. Given the burden of injury after the 2010 earthquake, further research on long

    On 12 January 2010 a magnitude Mw 7.0 earthquake occurred 25 km west-southwest of Haiti’s Capital of Port-au-Prince, which resulted in more than 230,000 fatalities. In addition tsunami waves triggered by the earthquake caused at least 3 fatalities at Petit Paradis. Unfortunately, the people of Haiti had neither ancestral knowledge nor educational awareness of tsunami hazards despite the 1946 Dominican Republic tsunami at Hispaniola’s northeast coast. In sharp contrast Sri Lankan UN-soldiers on duty at Jacmel self-evacuated given the memory of the 2004 Indian Ocean tsunami. The International Tsunami Survey Team (ITST) documented flow depths, runup heights, inundation distances, sediment deposition, damage patterns at various scales, and performance of the man-made infrastructure and impact on the natural environment. The 31 January to 7 February 2010 ITST covered the greater Bay of Port-au-Prince and more than 100 km of Hispaniola’s south coast between Pedernales, Dominican Republic and Jacmel, Haiti. The Hispaniola survey data includes more than 20 runup and flow depth measurements. The tsunami impacts peaked with maximum flow depths exceeding 3 m both at Petit Paradis inside the Bay of Grand Goâve located 45 km west-southwest of Port-au-Prince and at Jacmel on Haiti’s south coast. A significant variation in tsunami impact was observed on Hispaniola and tsunami runup of more than 1 m was still observed at Pedernales in the Dominican Republic. Jacmel, which is near the center of the south coast, represents an unfortunate example of a village and harbor that was located for protection from storm waves but is vulnerable to tsunami waves with runup doubling from the entrance to the head of the bay. Inundation and damage was limited to less than 100 m inland at both Jacmel and Petit Paradis. Differences in wave period were documented between the tsunami waves at Petit Paradis and Jacmel. The Petit Paradis tsunami is attributed to a coastal submarine landslide

    Sickle cell disease is a growing global health concern because infants born with the disorder in developing countries are now surviving longer with little access to diagnostic and management options. In Haiti, the current state of sickle cell disease/trait in the population is unclear. To inform future screening efforts in Haiti, we assayed sickle hemoglobin mutations using traditional hemoglobin solubility tests (HST) and add-on techniques, which incorporated spectrophotometry and insoluble hemoglobin separation. We also generated genotype data as a metric for HST performance. We found 19 of 202 individuals screened with HST were positive for sickle hemoglobin, five of whom did not carry the HbS allele. We show that spectrophotometry and insoluble hemoglobin separation add-on techniques could resolve false positives associated with the traditional HST approach, with some limitations. We also discuss the incorporation of insoluble hemoglobin separation observation with HST in suboptimal screening settings like Haiti. PMID:24957539

    2012-01-01

    Cholera is an acute watery diarrheal disease caused by infection with Vibrio cholerae. The disease has a high fatality rate when untreated and outbreaks of cholera have been increasing globally in the past decade, most recently in Haiti. We present the case of a 28-year-old Haitian male with a history of severe untreated mental health disorder that developed acute fatal watery diarrhea in mid-October 2010 in central Haiti after drinking from the local river. We believe he is the first or among the first cases of cholera in Haiti during the current epidemic. By reviewing his case, we extracted lessons for global health on the importance of mental health for overall health, the globalization of diseases in small communities, and the importance of a comprehensive approach to the health of communities when planning services in resource-poor settings.

    2016-01-01

    This article discusses the functioning of a health-oriented development project pursued in an emergency situation and its impacts beyond its stated goals. The tripartite project between Brazil, Haiti, and Cuba was designed to strengthen Haiti's health and epidemiologic surveillance system, introduced in 2010 as part of the aid effort after the earthquake. An essentially ethnographic perspective is taken, with a focus on describing the practices and perspectives of the agents involved in the program. The networks of agents were mapped out, paying particular attention to translators, drivers, and journalists, who were understood as being "cooperation brokers". Finally, the article discusses the project's position in the broader context of international health initiatives in Haiti.

    Describing factors related to high attrition is important in order to improve the implementation of the Option B+ strategy in Haiti. We conducted a retrospective cohort study to describe the variability of antiretroviral therapy (ART) retention across health facilities among pregnant and lactating women and assess for differences in ART retention between Option B+ clients and other ART patients. There were 1989 Option B+ clients who initiated ART in 45 health facilities. The percentage of attrition varied from 9% to 81% across the facilities. The largest health facilities had 38% higher risk of attrition (relative risk [RR]: 1.38, 95% confidence interval [CI]: 1.08-1.77, P = .009). Private institutions had 18% less risk of attrition (RR: 0.82, 95% CI: 0.70-0.96, P = .020). Health facilities located in the West department and the South region had lower risk of attrition. Being on treatment in a large or public health facility or a facility located in the North region was a significant risk factor associated with high attrition among Option B+ clients. The implementation of the Option B+ strategy must be reevaluated in order to effectively eliminate mother-to-child HIV transmission.

    The U.S. Geological Survey produced 1:24,000-scale post-earthquake image base maps incorporating high- and medium-resolution remotely sensed imagery following the 7.0 magnitude earthquake near the capital city of Port au Prince, Haiti, on January 12, 2010. Commercial 2.4-meter multispectral QuickBird imagery was acquired by DigitalGlobe on January 15, 2010, following the initial earthquake. Ten-meter multispectral ALOS AVNIR-2 imagery was collected by the Japanese Space Agency (JAXA) on January 12, 2010. These data were acquired under the Remote Sensing International Charter, a global team of space and satellite agencies that provide timely imagery in support of emergency response efforts worldwide. The images shown on this map were employed to support earthquake response efforts, specifically for use in determining ground deformation, damage assessment, and emergency management decisions. The raw, unprocessed imagery was geo-corrected, mosaicked, and reproduced onto a cartographic 1:24,000-scale base map. These maps are intended to provide a temporally current representation of post-earthquake ground conditions, which may be of use to decision makers and to the general public.

    Vaginal symptoms are a common chief complaint amongst women visiting outpatient clinics in rural Haiti. A systematic sample of 206 consecutive women over age 18 with gynaecological symptoms underwent gynaecologic examination and laboratory testing for chlamydia, gonorrhoea, syphilis, HIV infection, trichomoniasis, candidiasis, and bacterial vaginosis. Among 206 women, 174 (84%) presented with vaginal discharge, 165 (80%) with vaginal itching, 123 (60%) with vaginal pain or dysuria, and 18 (9%) with non-traumatic vaginal sores or boils. Laboratory results were positive forChlamydia trachomatisin 5.4% (11/203), syphilis in 3.5% (7/202), HIV in 1.0% (2/200), andNeisseria gonorrhoeaein 1.0% (2/203). Among those that had microscopy, hyphae suggestive of candidiasis were visualized in 2.2% (1/45) and no cases of trichomoniasis were diagnosed 0% (0/45). Bacterial vaginosis was diagnosed in 28.3% (13/46). The prevalence of chlamydia was 4.9 (95% CI: 1.3-17.7) times greater among those 25 years of age and under (10.8%) than those older (2.3%). Chlamydia and bacterial vaginosis were the most common sexually transmitted infection and vaginal condition, respectively, in this study of rural Haitian adult women. The higher risk of chlamydia in younger women suggests education and screening programmes in young women should be considered. © The Author(s) 2013 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

  6. Water-resources reconnaissance of Isle de la Gonave, Haiti

    Troester, J.W.; Turvey, M.D.

    2004-01-01

    Isle de la Gonave is a 750-km2 island off the coast of Haiti. The depth to the water table ranges from less than 30 m in the Eocene and Upper Miocene limestones to over 60 m in the 300-m-thick Quaternary limestone. Annual precipitation ranges from 800-1,400 mm. Most precipitation is lost through evapotranspiration and there is virtually no surface water. Roughly estimated from chloride mass balance, about 4% of the precipitation recharges the karst aquifer. Cave pools and springs are a common source for water. Hand-dug wells provide water in coastal areas. Few productive wells have been drilled deeper than 60 m. Reconnaissance field analyses indicate that groundwater in the interior is a calcium-bicarbonate type, whereas water at the coast is a sodium-chloride type that exceeds World Health Organization recommended values for sodium and chloride. Tests for the presence of hydrogen sulfide-producing bacteria were negative in most drilled wells, but positive in cave pools, hand-dug wells, and most springs, indicating bacterial contamination of most water sources. Because of the difficulties in obtaining freshwater, the 110,000 inhabitants use an average of only 7 L per person per day.

    2010-01-01

    Initially, the devastating Mw 7.0, 12 January 2010 Haiti earthquake seemed to involve straightforward accommodation of oblique relative motion between the Caribbean and North American plates along the Enriquillog-Plantain Garden fault zone. Here, we combine seismological observations, geologic field data and space geodetic measurements to show that, instead, the rupture process may have involved slip on multiple faults. Primary surface deformation was driven by rupture on blind thrust faults with only minor, deep, lateral slip along or near the main Enriquillog-Plantain Garden fault zone; thus the event only partially relieved centuries of accumulated left-lateral strain on a small part of the plate-boundary system. Together with the predominance of shallow off-fault thrusting, the lack of surface deformation implies that remaining shallow shear strain will be released in future surface-rupturing earthquakes on the Enriquillog-Plantain Garden fault zone, as occurred in inferred Holocene and probable historic events. We suggest that the geological signature of this earthquakeg-broad warping and coastal deformation rather than surface rupture along the main fault zoneg-will not be easily recognized by standard palaeoseismic studies. We conclude that similarly complex earthquakes in tectonic environments that accommodate both translation and convergenceg-such as the San Andreas fault through the Transverse Ranges of Californiag-may be missing from the prehistoric earthquake record. ?? 2010 Macmillan Publishers Limited.

    Full Text Available Intensive or inadequate management of tourism and related development may affect the nature, integrity and the dominant features of an area. Local communities hosting tourism often are the weaker link which interacts with guests and service providers within the tourism value chain. Therefore, tourism development should embrace the paradigm of sustainability by improving the living conditions of host communities, ensuring efficient use of the resources available, and valorizing and preserving local heritage and traditions from any damages or loss. This paper examines the extent to which tourism development may affect social, economic, and environmental conditions of communities of the Sud Department of Haiti particularly Les Cayes. To meet the objective of this paper, we surveyed of 453 residents and examined their views on the influence of tourism development in the region. By using conducting this survey, we gathered insights on what is considered significant for the respondents, and also an assessed the influence of number of residents, place of residence, and coastal vs. Inland on residents' perceptions.

    2011-03-01

    Full Text Available As the world joins forces to support the people of Haiti on their long road of recovery following the January 2010 earthquake, plans and strategies should take into consideration past experiences from other postdisaster recovery efforts with respect to integrating ecosystem considerations. Sound ecosystem management can both support the medium and long-term needs for recovery as well as help to buffer the impacts of future extreme natural events, which for Haiti are likely to include both hurricanes and earthquakes. An additional challenge will be to include the potential impacts of climate change into ecosystem management strategies.

  10. A model for establishing and developing relationships with visitors of the Kopački rit Nature Park based on mobile technologies

    2015-03-01

    Full Text Available Kopački rit as a nature park is a great tourist attractor in northeastern Croatia. Its flora and fauna used to attract people for economic reasons, whereas today people mostly visit it for educational and tourism purposes. Visitor loyalty is increasingly important in tourism development today. One-time visitors cannot be the basis of tourist demand. Such guests often visit a particular destination motivated by global political trends, and not by the need to visit the destination itself. For example, the increased number of guests in Croatia in the past few years is a result of political events in Greece and North Africa. Once the political situation in their primary choice is stabilised, such guests will be lost. Therefore, among many guests of Kopački rit one must recognise those, for whom it was their primary destination, and establish a relationship with them. To achieve a targeted tourist offer, the Nature Park must implement relationship marketing by means of Customer Relationship Management (CRM. The aim of this research is to explore and define an optimum model of the CRM system that would offer a long-term solution to the problem of customer relationship development with visitors to Kopački rit. The research will be carried out deductively, and the methods used to realize the research aim are to be systematic analysis, causal reasoning, descriptive modelling, and logical experiment. The result is a framework model of a marketing database and a descriptive conceptual model of the CRM system for Kopački rit, both of which will use the potentials of mobile and information and communication technologies.

    The MADIT-RIT trial demonstrated reduction of inappropriate and appropriate ICD therapies and mortality by high-rate cut-off and 60-second-delayed VT therapy ICD programming in patients with a primary prophylactic ICD indication. The aim of this analysis was to study effects of MADIT-RIT ICD programming in patients with ischemic and nonischemic cardiomyopathy. First and total occurrences of both inappropriate and appropriate ICD therapies were analyzed by multivariate Cox models in 791 (53%) patients with ischemic and 707 (47%) patients with nonischemic cardiomyopathy. Patients with ischemic and nonischemic cardiomyopathy had similar incidence of first inappropriate (9% and 11%, P = 0.21) and first appropriate ICD therapy (11.6% and 14.1%, P = 0.15). Patients with ischemic cardiomyopathy had higher mortality rate (6.1% vs. 3.3%, P = 0.01). MADIT-RIT high-rate cut-off (arm B) and delayed VT therapy ICD programming (arm C) compared with conventional (arm A) ICD programming were associated with a significant risk reduction of first inappropriate and appropriate ICD therapy in patients with ischemic and nonischemic cardiomyopathy (HR range 0.11-0.34, P programming and delayed VT therapy ICD programming in both ischemic and nonischemic cardiomyopathy patients. High-rate cut-off and delayed VT therapy ICD programming are associated with significant reduction in first and total inappropriate and appropriate ICD therapy in patients with ischemic and nonischemic cardiomyopathy. © 2014 Wiley Periodicals, Inc.

    2013-07-01

    Full Text Available This paper represents one of the first measurements of volatile hydrocarbon concentrations within the surface layer of the troposphere in Tikveš, Kopaeki Rit Nature Park. This Nature Park is situated about 20 kilometres from the city of Osijek and represents an interesting example of the interaction of the urban and rural (wetland areas, which is also the reason for selecting the Tikveš site as the measurement station.Volatile organic compounds with two to seven carbon atoms were measured and analysed on a gas chromatograph with flame ionization (FID and mass-selective detector (MSD. The results for the hydrocarbons with 2 to 7 carbon atoms are shown. Ozone volume fractions in the air were also measured. All data obtained are given as hourly averages: for volatile hydrocarbons of concentrations and for ozone of volume fractions. The most significant changes in the concentration were found for ethane, propane and butane. With the exception of isoprene, whose daily concentration changes similarly as found for ozone, the daily variations of the measured hydrocarbons in Tikveš differ from the observed ozone diurnal variation. The Spearman's test showed no significant negative correlation between the measured hydrocarbons.

    The procedure guideline for radioiodine therapy (RIT) of differentiated thyroid cancer (version 3) is the counterpart to the procedure guideline for {sup 131}I whole-body scintigraphy (version 3) and specify the interdisciplinary guideline for thyroid cancer of the Deutsche Krebsgesellschaft concerning the nuclear medicine part. Recommendation for ablative {sup 131}I therapy is given for all differentiated thyroid carcinoma (DTC) >1 cm. Regarding DTC {<=}1 cm {sup 131}I ablation may be helpful in an individual constellation. Preparation for {sup 131}I ablation requires low iodine diet for two weeks and TSH stimulation by withdrawal of thyroid hormone medication or by use of recombinant human TSH (rhTSH). The advantages of rhTSH (no symptoms of hypothyroidism, lowerblood activity) and the advantages of endogenous TSH stimulation (necessary for {sup 131}I-therapy in patients with metastases, higher sensitivity of {sup 131}I whole-body scan) are discussed. In most centers standard activities are used for {sup 131}I ablation. If pretherapeutic dosimetry is planned, the diagnostic administration of {sup 131}I should not exceed 1-10MBq, alternative tracers are {sup 123}I or {sup 124}I. The recommendations for contraception and family planning are harmonized with the recommendation of ATA and ETA. Regarding the best possible protection of salivary glands the evidence is insufficient to recommend a specific setting. To minimize the risk of dental caries due to xerostomia patients should use preventive strategies for dental hygiene. (orig.)

    Full Text Available This study examines the differences among students in terms of self-reported leadership characteristics. It was conducted among all three programs and four generations of undergraduates at RIT Croatia. The goal of this study is to determine the differences among students who report being more and less leadership prone (Potential Future Leaders and Followers, respectively with regard to demographic characteristics, reported self reliance socialization pattern, college level and program choice, career focus attainment and development, and reported attitudes regarding the importance of specific personality traits in leadership, the importance of specific career development factors and success indicators. Research showed that generation and college program are not related to student reported leadership proneness, suggesting that college education’s impact on leadership traits is not significant. Only one socio-demographic factor considered was significantly different between clusters; namely, the respondents who had moved once were significantly more represented in the Potential Future Leaders cluster, suggesting that study-abroad programs might play a role in leadership development. In terms of ranking career development factors, success indicators, the importance of emotional stability and openness to experience as a specific leadership trait, Potential Future Leaders reported higher scores in comparison with Followers cluster, potentially resulting from their forwardlooking, goal-oriented attitude.

    With increasing population displacement and worsening water insecurity after the 2010 earthquake, Haiti experienced a large cholera outbreak. Our goal was to evaluate the strengths and weaknesses of seven community health facilities' ability to respond to a surge in cholera cases. Since 2010, Catholic Relief Services (CRS) with a number of public and private donors has been working with seven health facilities in an effort to reduce morbidity and mortality from cholera infection. In November 2012, CRS through the Centers for Disease Control and Prevention (CDC)'s support, asked the Johns Hopkins Center for Refugee and Disaster Response to conduct a cholera surge simulation tabletop exercise at these health facilities to improve each facility's response in the event of a cholera surge. Using simulation development guidelines from the Pan American Health Organization and others, a simulation scenario script was produced that included situations of differing severity, supply chain, as well as a surge of patients. A total of 119 hospital staff from seven sites participated in the simulation exercise including community health workers, clinicians, managers, pharmacists, cleaners, and security guards. Clinics that had challenges during the simulated clinical care of patients were those that did not appropriately treat all cholera patients according to protocol, particularly those that were vulnerable, those that would need additional staff to properly treat patients during a surge of cholera, and those that required a better inventory of supplies. Simulation-based activities have the potential to identify healthcare delivery system vulnerabilities that are amenable to intervention prior to a cholera surge.

    To evaluate the implementation of a time-driven activity-based costing analysis at five community health facilities in Haiti. Together with stakeholders, the project team decided that health-care providers should enter start and end times of the patient encounter in every fifth patient's medical dossier. We trained one data collector per facility, who manually entered the time recordings and patient characteristics in a database and submitted the data to a cloud-based data warehouse each week. We calculated the capacity cost per minute for each resource used. An automated web-based platform multiplied reported time with capacity cost rate and provided the information to health-facilities administrators. Between March 2014 and June 2015, the project tracked the clinical services for 7162 outpatients. The cost of care for specific conditions varied widely across the five facilities, due to heterogeneity in staffing and resources. For example, the average cost of a first antenatal-care visit ranged from 6.87 United States dollars (US$) at a low-level facility to US$ 25.06 at a high-level facility. Within facilities, we observed similarly variation in costs, due to factors such as patient comorbidities, patient arrival time, stocking of supplies at facilities and type of visit. Time-driven activity-based costing can be implemented in low-resource settings to guide resource allocation decisions. However, the extent to which this information will drive observable changes at patient, provider and institutional levels depends on several contextual factors, including budget constraints, management, policies and the political economy in which the health system is situated.

    On January 12, 2010, a 7.0-magnitude earthquake struck Haiti. The event disrupted infrastructure and was marked by extreme morbidity and mortality. The global response to the disaster was rapid and immense, comprising multiple actors-including academic health centers (AHCs)-that provided assistance in the field and from home. The authors retrospectively examine the multidisciplinary approach that the University of Chicago Medicine (UCM) applied to postearthquake Haiti, which included the application of institutional structure and strategy, systematic deployment of teams tailored to evolving needs, and the actual response and recovery. The university mobilized significant human and material resources for deployment within 48 hours and sustained the effort for over four months. In partnership with international and local nongovernmental organizations as well as other AHCs, the UCM operated one of the largest and more efficient acute field hospitals in the country. The UCM's efforts in postearthquake Haiti provide insight into the role AHCs can play, including their strengths and limitations, in complex disasters. AHCs can provide necessary intellectual and material resources as well as technical expertise, but the cost and speed required for responding to an emergency, and ongoing domestic responsibilities, may limit the response of a large university and hospital system. The authors describe the strong institutional backing, the detailed predeployment planning and logistical support UCM provided, the engagement of faculty and staff who had previous experience in complex humanitarian emergencies, and the help of volunteers fluent in the local language which, together, made UCM's mission in postearthquake Haiti successful.

    The West Indies represent an amalgamation of African, European and in some cases, East Asian sources, but the contributions from each ethnic group remain relatively unexplored from a genetic perspective. In the present study, we report, for the first time, allelic frequency data across the complete set of 15 autosomal STR loci for general collections from Haiti and Jamaica, which were subsequently used to examine the genetic diversity present in each island population. Our results indicate that although both Haiti and Jamaica display genetic affinities with the continental African collections, a stronger African signal is detected in Haiti than in Jamaica. Although only minimal contributions from non-African sources were observed in Haiti, Jamaica displays genetic input from both European and East Asian sources, an admixture profile similar to other New World collections of African descent analyzed in this report. The divergent genetic signatures present in these populations allude to the different migratory events of Africans, Europeans, and East Asians into the New World.

    No strong motion records are available for the 12 January 2010 M7.0 Haiti earthquake. We use aftershock recordings as well as detailed considerations of damage to estimate the severity and distribution of mainshock shaking in Port-au-Prince. Relative to ground motions at a hard - rock reference site, peak accelerations are amplified by a factor of approximately 2 at sites on low-lying deposits in central Port-au-Prince and by a factor of 2.5 - 3.5 on a steep foothill ridge in the southern Port-au-Prince metropolitan region. The observed amplification along the ridge cannot be explained by sediment - induced amplification , but is consistent with predicted topographic amplification by a steep, narrow ridge. Although damage was largely a consequence of poor construction , the damage pattern inferred from analysis of remote sensing imagery provides evidence for a correspondence between small-scale (0.1 - 1.0 km) topographic relief and high damage. Mainshock shaking intensity can be estimated crudely from a consideration of macroseismic effects . We further present detailed, quantitative analysis of the marks left on a tile floor by an industrial battery rack displaced during the mainshock, at the location where we observed the highest weak motion amplifications. Results of this analysis indicate that mainshock shaking was significantly higher at this location (~0.5 g , MMI VIII) relative to the shaking in parts of Port-au-Prince that experienced light damage. Our results further illustrate how observations of rigid body horizontal displacement during earthquakes can be used to estimate peak ground accelerations in the absence of instrumental data .

    The degree to which local health systems contribute to reductions in under-five mortality in severely impoverished settings has not been well documented. The current study compares the under-five mortality in the Hôpital Albert Schweitzer (HAS) Primary Health Care Service Area with that for Haiti in general. HAS provides an integrated system of community-based primary health care services, hospital care and community development. A sample of 10% of the women of reproductive age in the HAS service area was interviewed, and 2390 live births and 149 child deaths were documented for the period 1995-99. Under-five mortality rates were computed and compared with rates for Haiti. In addition, available data regarding inputs, processes and outputs for the HAS service area and for Haiti were assembled and compared. Under-five mortality was 58% less in the HAS service area, and mortality for children 12-59 months of age was 76% less. These results were achieved with an input of fewer physicians and hospital beds per capita than is available for Haiti nationwide, but with twice as many graduate nurses and auxiliary nurses per capita than are available nationwide, and with three cadres of health workers that do not exist nationwide: Physician Extenders, Health Agents and Community Health Volunteers. The population coverage of targeted child survival services was generally 1.5-2 times higher in the HAS service area than in rural Haiti. These findings support the conclusion that a well-developed system of primary health care, with outreach services to the household level, integrated with hospital referral care and community development programmes, can make a strong contribution to reducing infant and child mortality in severely impoverished settings.

    The left-lateral Enriquillo-Plantain Garden Fault (EPGF) is one of two major transform faults that form the North American-Caribbean plate boundary. GPS measurements indicate that relative motion evolves from nearly pure strike-slip in western Haiti to highly transpressional near Lake Azuei in eastern Haiti, where the EPGF may terminate against a south-dipping oblique reverse fault. Lake Azuei, one of the largest lakes in the Caribbean region (10 km x 23 km), is surrounded by two high-elevation sierras (> 2,000 m). Because the lake has no outlet to the sea, its level is sensitive to variations in precipitation and is thought to have fluctuated by 10's of meters during the Holocene. A rise of 5 m over the past 10 years has had a devastating impact, submerging villages, farmland, and roads. A grid of high-resolution ( 10 cm) subbottom seismic (CHIRP) profiles acquired in January 2017 captures the subtle signature of the 5 m-deep shoreline and also images a prominent paleo-shoreline at 10 m water depth. This 10 m paleo-shoreline is well expressed in the CHIRP data suggesting it was occupied for a long period of time. It is buried beneath a thin (water depths of 14 m and 17 m, each bottomed 80-90 cm below the lakebed into a distinctively coarser bed. On-going radiometric dating is expected to constrain the age of this distinctive layer. Should this layer be tied to the perduring 10-m lowstand of the lake, determining its age could help quantify vertical deformation rates around Lake Azuei.

  17. Evidence for higher tropical storm risks in Haiti due to increasing population density in hazard prone urban areas

    International Nuclear Information System (INIS)

    Klose, Christian D

    2011-01-01

    Since the 18th century, the Republic of Haiti has experienced numerous tropical cyclones. In 2011, the United Nations Global Assessment Report on Disaster Risk Reduction outlined that the worldwide physical exposure to natural hazards, which includes tropical storms and hurricanes in Haiti, increased by 192 per cent between 1970 and 2010. Now, it can be hypothesized that the increased physical exposure to cyclones that made landfall in Haiti has affected the country's development path. This study shows that tropical storm risks in Haiti increased due to more physical exposure of the population in urban areas rather than a higher cyclone frequency in the proximity of Hispaniola island. In fact, the population density accelerated since the second half of the 20th century in regions where historically more storms made landfall, such as in the departments Ouest, Artibonite, Nord and Nord-Ouest including Haiti's four largest cities: Port-au-Prince, Gonaïves, Cap-Haïtien and Port-de-Paix. Thus, urbanization in and migration into storm hazard prone areas could be considered as one of the major driving forces of Haiti's fragility.

    Romulus, Elijah Rey Asse

    This paper explores and analyzes energy justice and the stakeholders involved. Energy insecurity, specifically the lack of access to electricity effects over 1.3 billion people worldwide and energy justice is a way to address it. This paper is supported by a case study with data collected in the southern rural regions of Haiti regarding energy justice communities. Three cities were studied: Les Cayes, Anse-a-Veau, and Les Anglais. It examines how solar businesses can aid energy justice communities seeking access to electricity. Stakeholders such as the communities themselves, solar businesses, and nonprofits in the region are studied and analyzed. The paper concludes solar businesses are helping said communities but needs participation from other stakeholders to be successful. Finally, there are five recommendations to build capacity, develop infrastructure in the region, explore the possibility of solar cooperatives, strengthen the solar economy in Haiti, and demand reparations.

    In January 2010, a massive earthquake struck Haiti resulting in unprecedented damage. Little attention, however, has focused on the earthquake's mental health impact in the Haitian diaspora community. As part of an established community-based participatory research initiative in Little Haiti, the predominately Haitian neighborhood in Miami, FL, USA, community health workers conducted surveys with neighborhood residents about earthquake-related losses, coping strategies, and depressive/traumatic symptomology. Findings reveal the earthquake strongly impacted the diaspora community and highlights prominent coping strategies. Following the earthquake, only a small percentage of participants self-reported engaging in any negative health behaviors. Instead, a majority relied on their social networks for support. This study contributes to the discourse on designing culturally-responsive mental health initiatives for the Haitian diaspora and the ability of existing community-academic partnerships to rapidly adapt to community needs.

    The vulnerability of children in Haiti has increased dramatically since the earthquake in January 2010. Prior to the earthquake, the prevalence of orphans and at-risk children was high but since the earthquake, more than 1 million people-with more than 380,000 children remaining displaced and living in over 1200 displacement sites. These existing conditions leave orphans and at-risk children vulnerable to exploitation, abuse, and increased risk of HIV/AIDS. This article will focus on the complex issues affecting orphans and at-risk children and the intersection with HIV/AIDS and human rights. Specific recommendations by United Nations Children's Fund are discussed. Nursing in Haiti must address the policy-related and population-specific approaches for the care of children living with or affected by HIV/AIDS.

    Haiti's 2010 earthquake mobilized mental health and psychosocial interventions from across the globe. However, failure to understand how psychological distress is communicated between lay persons and health workers in rural clinics, where most Haitians access care, has been a major limitation in providing mental health services. The goal of this study was to map idioms of distress onto Haitian ethnopsychologies in a way that promotes improved communication between lay persons and clinicians in rural Haiti. In Haiti's Central Plateau, an ethnographic study was conducted in May and June 2010, utilizing participant observation in rural clinics, 31 key informant interviews, 11 focus groups, and four case studies. Key informants included biomedical practitioners, traditional healers, community leaders, and municipal and religious figures. Deductive and inductive themes were coded using content analysis (inter-rater reliability > 0.70). Forty-four terms for psychological distress were identified. Head (tèt) or heart (kè) terms comprise 55% of all qualitative text segments coded for idioms of distress. Twenty-eight of 142 observed patient-clinician contacts involved persons presenting with tèt terms, while 29 of the 142 contacts were presentations with kè terms. Thus, 40% of chief complaints were conveyed in either head or heart terms. Interpretations of these terms differed between lay and clinical groups. Lay respondents had broad and heterogeneous interpretations, whereas clinicians focused on biomedical concepts and excluded discussion of mental health concerns. This paper outlines preliminary evidence regarding the psychosocial dimensions of tèt and kè-based idioms of distress and calls for further exploration. Holistic approaches to mental healthcare in Haiti's Central Plateau should incorporate local ethnopsychological frameworks alongside biomedical models of healthcare. Copyright © 2012 Elsevier Ltd.

    An estimated 59 000 persons die annually of infection with the rabies virus worldwide, and dog bites are responsible for 95% of these deaths. Haiti has the highest rate of animal and human rabies in the Western Hemisphere. This study describes the status of animal welfare, animal vaccination, human bite treatment, and canine morbidity and mortality in Haiti in order to identify barriers to rabies prevention and control. An epidemiologic survey was used for data collection among dog owners during government-sponsored vaccination clinics at fourteen randomly selected sites from July 2014 to April 2015. A total of 2005 surveys were collected and data were analysed using parametric methods. Over 50% of owned dogs were allowed to roam freely, a factor associated with rabies transmission. More than 80% of dog owners reported experiencing barriers to accessing rabies vaccination for their dogs. Nearly one-third of the dog population evaluated in this study died in the year preceding the survey (32%) and 18% of these deaths were clinically consistent with rabies. Dog bites were commonly reported, with more than 3% of the study population bitten within the year preceding the survey. The incidence of canine rabies in Haiti is high and is exacerbated by low access to veterinary care, free-roaming dog populations and substandard animal welfare practices. Programmes to better understand the dog ecology and development of methods to improve access to vaccines are needed. Rabies deaths are at historical lows in the Western Hemisphere, but Haiti and the remaining canine rabies endemic countries still present a significant challenge to the goal of rabies elimination in the region.

    The present study aims to: (1) estimate the levels of internalizing symptoms and externalizing behaviors among youth affected by HIV in central Haiti; and (2) examine the risk and protective factors associated with these outcomes to identify potential areas of intervention for HIV-affected youth. Baseline data for 492 youth affected by HIV (ages 10-17) and their 330 caregivers were collected for a pilot study of a psychosocial support intervention. Participants were recruited from a list of HIV-positive patients receiving care at Partners In Health/Zanmi Lasante clinic sites. Internalizing and externalizing behaviors were assessed using the Strengths and Difficulties Questionnaire. Demographic, economic, and social indicators were collected using a structured questionnaire administered by trained social workers. Youth affected by HIV in central Haiti displayed high levels of internalizing and, to a lesser degree, externalizing symptoms. Multivariate regression analysis demonstrated risk factors most strongly associated with internalizing symptoms (socioeconomic status, parental depressive symptoms) and externalizing behaviors (household living arrangements, such as living with a stepparent). Social support had a protective effect on externalizing behaviors for both caregiver (β=-0.03, p=0.01) and self-report (β=-0.05, pHaiti and similar resource-limited settings.

    Hepatitis B vaccine administered shortly after birth is highly effective in preventing mother to child transmission (MTCT) of infection. While hepatitis B vaccine was introduced in Haiti as part of a combined pentavalent vaccine in 2012, a birth dose is not yet included in the immunization schedule. Determine the seroprevalence of hepatitis B virus (HBV) infection among pregnant women to evaluate the risk of MTCT. We selected 1364 residual serum specimens collected during a 2012 human immunodeficiency virus (HIV) sentinel serosurvey among pregnant women attending antenatal care clinics. Haiti was stratified into two regions: West, which includes metropolitan Port-au-Prince, and non-West, which includes all other departments. We evaluated the association between demographic and socioeconomic characteristics and HIV infection with HBV infection. Of 1364 selected specimens, 1307 (96%) were available for testing. A total of 422 specimens (32.7%) tested positive for total anti-HBc (38.2% in West vs. 27% in non-West, pHaiti has an intermediate endemicity of chronic HBV infection with high prevalence of positive HBV DNA among chronically infected women.

    Haiti is one of two remaining malaria-endemic countries in the Caribbean. To decrease malaria transmission in Haiti, primaquine was recently added to the malaria treatment public health policy. One limitation of primaquine is that, at certain doses, primaquine can cause hemolytic anemia in individuals with glucose-6-phosphate dehydrogenase (G6PD) deficiency (G6PDd). In this study, we genotyped two mutations (A376G and G202A), which confer the most common G6PDd variant in West African populations, G6PDd A−. We estimated the frequency of G6PDd A− in a sample of febrile patients enrolled in an on-going malaria study who represent a potential target population for a primaquine mass drug administration. We found that 33 of 168 individuals carried the G6PDd A− allele (includes A− hemizygous males, A− homozygous or heterozygous females) and could experience toxicity if treated with primaquine. These data inform discussions on safe and effective primaquine dosing and future malaria elimination strategies for Haiti. PMID:24891465

    The damage to medical facilities resulting form the January 2010 earthquake in haiti necessitated the establishment of field tent hospitals. Much of the local medical infrastructure was destroyed or limited operationally when the Fast Israel Rescue and Search Team (FIRST) arrived in Haiti shortly after the January 2010 earthquake. The FIRST deployed small tent hospitals in Port-au-Prince and in 11 remote areas outside of the city. Each tent was set up in less than a half hour. The tents were staffed with an orthopedic surgeon, gynecologists, primary care and emergency care physicians, a physician with previous experience in tropical medicine, nurses, paramedics, medics, and psychologists. The rapidly deployable and temporary nature of the effort allowed the team to treat and educate, as well as provide supplies for, thousands of refugees throughout Haiti. In addition, a local Haitian physician and his team created a small tent hospital to serve the Petion Refugee Camp and its environs. FIRST personnel also took shifts at this hospital.

    Haiti is regarded as the poorest country of the Western hemisphere. The Hôpital Albert Schweitzer (HAS), founded in 1956 by Larimer Melon, is providing medical care to the Artibonite valley, an area in the centre of Haiti with over 400 000 inhabitants. Until 2001, a three-fold population was without eye care in central Haiti. In 2001, Hans Rudolf Bracher, a retired ophthalmologist from Bern, initiated the eye department at HAS and organised an eye examination unit, a microscope and further surgical equipment. Since then, eye care to the population was provided by short-term visits of ophthalmologists, nurses and orthoptists, mainly from switzerland. Additionally, teaching and surgical training was performed at university hospital in Port-au-Price, the only education centre for ophthalmologists in the country. The actual political and security situation complicates visits of western doctors. A development association for the HAS eye department was founded and with its help, an Haitian ophthalmologist is employed in a full-time position. Furthermore, logistic support is provided with drugs and surgical equipment. Today, under difficult circumstances, the eye department is well established as an effective and cost-covering institution at HAS.

    The devastating 2010 cholera epidemic in Haiti prompted the government to introduce oral cholera vaccine (OCV) in two high-risk areas of Haiti. We evaluated the direct costs associated with the government's first vaccine campaign implemented in August-September 2013. We analyzed data for major cost categories and assessed the efficiency of available campaign resources to vaccinate the target population. For a target population of 107,906 persons, campaign costs totaled $624,000 and 215,295 OCV doses were dispensed. The total vaccine and operational cost was $2.90 per dose; vaccine alone cost $1.85 per dose, vaccine delivery and administration $0.70 per dose, and vaccine storage and transport $0.35 per dose. Resources were greater than needed-our analyses suggested that approximately 2.5-6 times as many persons could have been vaccinated during this campaign without increasing the resources allocated for vaccine delivery and administration. These results can inform future OCV campaigns in Haiti.

    After the 2010 earthquake, Haiti committed to introducing 4 new antigens into its routine immunization schedule, which required improving its cold chain (ie, temperature-controlled supply chain) and increasing vaccine storage capacity by installing new refrigerators. We tested the feasibility of using remote temperature monitoring devices (RTMDs) in Haiti in a sample of vaccine refrigerators fueled by solar panels, propane gas, or electricity. We analyzed data from 16 RTMDs monitoring 24 refrigerators in 15 sites from March through August 2014. Although 5 of the 16 RTMDs exhibited intermittent data gaps, we identified typical temperature patterns consistent with refrigerator door opening and closing, propane depletion, thermostat insufficiency, and overstocking. Actual start-up, annual maintenance, and annual electricity costs for using RTMDs were $686, $179, and $9 per refrigerator, respectively. In Haiti, RTMD use was feasible. RTMDs could be prioritized for use with existing refrigerators with high volumes of vaccines and new refrigerators to certify their functionality before use. Vaccine vial monitors could provide additional useful information about cumulative heat exposure and possible vaccine denaturation.

    Haiti is the poorest country in the Western Hemisphere and is heavily affected by food insecurity and malaria. To find out if these 2 conditions are associated with each other, we studied a convenience sample of 153 women with children 1-5 y old in Camp Perrin, South Haiti. Household food insecurity was assessed with the 16-item Escala Latinoamericana y Caribeña de Seguridad Alimentaria (ELCSA) scale previously validated in the target communities. ELCSA's reference time period was the 3 mo preceding the survey and it was answered by the mother. Households were categorized as either food secure (2%; ELCSA score = 0), food insecure/very food insecure (42.7%; ELCSA score range: 1-10), or severely food insecure (57.3%; ELCSA score range: 11-16). A total of 34.0% of women reported that their children had malaria during the 2 mo preceding the survey. Multivariate analyses showed that severe food insecure was a risk factor for perceived clinical malaria (odds ratio: 5.97; 95% CI: 2.06-17.28). Additional risk factors for perceived clinical malaria were as follows: not receiving colostrum, poor child health (via maternal self-report), a child BMI <17 kg/m(2), and child vitamin A supplementation more than once since birth. Findings suggest that policies and programs that address food insecurity are also likely to reduce the risk of malaria in Haiti.

    The boundary between the Caribbean (CA) and North American (NAM) plates in the Hispaniola region is the western prolongation of the NAM plate subduction evolving from a frontal subduction in the Lesser Antilles to an oblique collision against the Bahamas platform in Cuba. We analyze P-waveforms arriving at 27 broadband seismic temporary stations deployed along a 200 km-long N-S transect across Haiti, during the Trans-Haiti project. We compute teleseismic receiver functions using the ETMTRF method, and determine crustal thickness and bulk composition (Vp/Vs) using the H-k stacking method. Three distinctive crustal domains are imaged. We relate these domains to crustal terranes that have been accreted along the plate boundary during the northeastwards displacement of the CA plate. We propose a N-S crustal profile across Haiti accounting for the surface geology, shallow structural history and these new seismological constraints. Local seismicity recorded by the temporary network from April 2013 to June 2014 is used to relocate the seismicity. A total of 593 events were identified with magnitudes ranging from 1.6 to 4.5. This local seismicity, predominantly shallow (accommodation of an important part of convergence in this area.

  2. High-frequency rugose exopolysaccharide production by Vibrio cholerae strains isolated in Haiti.

    Full Text Available In October, 2010, epidemic cholera was reported for the first time in Haiti in over 100 years. Establishment of cholera endemicity in Haiti will be dependent in large part on the continued presence of toxigenic V. cholerae O1 in aquatic reservoirs. The rugose phenotype of V. cholerae, characterized by exopolysaccharide production that confers resistance to environmental stress, is a potential contributor to environmental persistence. Using a microbiologic medium promoting high-frequency conversion of smooth to rugose (S-R phenotype, 80 (46.5% of 172 V. cholerae strains isolated from clinical and environmental sources in Haiti were able to convert to a rugose phenotype. Toxigenic V. cholerae O1 strains isolated at the beginning of the epidemic (2010 were significantly less likely to shift to a rugose phenotype than clinical strains isolated in 2012/2013, or environmental strains. Frequency of rugose conversion was influenced by incubation temperature and time. Appearance of the biofilm produced by a Haitian clinical rugose strain (altered biotype El Tor HC16R differed from that of a typical El Tor rugose strain (N16961R by confocal microscopy. On whole-genome SNP analysis, there was no phylogenetic clustering of strains showing an ability to shift to a rugose phenotype. Our data confirm the ability of Haitian clinical (and environmental strains to shift to a protective rugose phenotype, and suggest that factors such as temperature influence the frequency of transition to this phenotype.

    To describe the epidemiology of malaria in pregnancy in Haiti. Cross-sectional study among pregnant women in six departments of Haiti. After obtaining informed consent, whole blood samples and demographic surveys were collected to investigate malaria prevalence, anaemia and socio-behavioural risk factors for infection, respectively. A total of 311 pregnant women were screened for Plasmodium falciparum infection using a rapid diagnostic test (RDT), microscopy and a novel, quantitative reverse transcriptase polymerase chain reaction method (qRT-PCR). Overall, 1.2% (4/311) of pregnant women were tested positive for malaria infection by both microscopy and RDT. However, using the qRT-PCR, 16.4% (51/311) of pregnant women were positive. The prevalence of malaria infection varied with geographical locations ranging between 0% and 46.4%. Additionally, 53% of pregnant women had some form of anaemia; however, no significant association was found between anaemia and submicroscopic malaria infection. The socio-behavioural risk factors identified to be protective of malaria infection were marital status (P < 0.05) and travel within one month prior to screening (P < 0.05). This study is the first to document the high prevalence of submicroscopic malaria infections among pregnant women in Haiti and identify social and behavioural risk factors for disease transmission. © 2017 John Wiley & Sons Ltd.

  4. Tsunami waves generated by dynamically triggered aftershocks of the 2010 Haiti earthquake

    Dynamically-triggered aftershocks, thought to be set off by the passage of surface waves, are currently not considered in tsunami warnings, yet may produce enough seafloor deformation to generate tsunamis on their own, as judged from new findings about the January 12, 2010 Haiti earthquake tsunami in the Caribbean Sea. This tsunami followed the Mw7.0 Haiti mainshock, which resulted from a complex rupture along the north shore of Tiburon Peninsula, not beneath the Caribbean Sea. The mainshock, moreover, had a mixed strike-slip and thrust focal mechanism. There were no recorded aftershocks in the Caribbean Sea, only small coastal landslides and rock falls on the south shore of Tiburon Peninsula. Nevertheless, a tsunami was recorded on deep-sea DART buoy 42407 south of the Dominican Republic and on the Santo Domingo tide gauge, and run-ups of ≤3 m were observed along a 90-km-long stretch of the SE Haiti coast. Three dynamically-triggered aftershocks south of Haiti have been recently identified within the coda of the mainshock (stacks, and back-projecting the arrivals to the vicinity of the main shock (50-300 km). Two of the aftershocks, coming 20-40 s and 40-60 s after the mainshock, plot along NW-SE-trending submarine ridges in the Caribbean Sea south of Haiti. The third event, 120-140 s was located along the steep eastern slope of Bahoruco Peninsula, which is delineated by a normal fault. Forward tsunami models show that the arrival times of the DART buoy and tide gauge times are best fit by the earliest of the three aftershocks, with a Caribbean source 60 km SW of the mainshock rupture zone. Preliminary inversion of the DART buoy time series for fault locations and orientations confirms the location of the first source, but requires an additional unidentified source closer to shore 40 km SW of the mainshock rupture zone. This overall agreement between earthquake and tsunami analyses suggests that land-based earthquake ruptures and/or non-thrust main shocks can

    2013-11-01

    The Republic of Haiti is a developing country in the Caribbean region with a history that challenges toxicologists, yet the historical panoply of toxicological hazards in Haiti has received little scholarly attention. The primary objectives of this paper are to review what is known about Haiti's current toxicological hazards, with a focus on chronic food-borne aflatoxin exposure and heavy metal contamination of water resources, and to compare these with previous large-scale, acute exposures to toxic substances: the 1995-1996 diethylene glycol (DEG) intoxications and the 2000-2001 ackee fruit poisonings. MEDLINE/PUBMED and the library website of Cornell University were searched using the terms "Haiti" and either "heavy metals," "aflatoxin", "diethylene glycol", or "ackee". The search was inclusive of articles from 1950 to 2012, and 15 out of the 37 returned were peer-reviewed articles offering original data or comprehensive discussion. One peer-reviewed article in press, two newspaper articles, two personal communications, and one book chapter from the personal databases of the authors were also referenced, making a total of 21 citations. Elevated concentrations of aflatoxins (greater than 20 μg/kg) were documented for staples of the Haitian food supply, most notably peanut butters and maize. Human exposure to aflatoxin was confirmed with analysis of aflatoxin blood biomarkers. The implications of aflatoxin exposure were reviewed in the light of Haiti's age-adjusted liver cancer risk - the highest in the Caribbean region. Measurement of heavy metals in Port-au-Prince ground water showed contamination of lead and chromium in excess of the US Environmental Protection Agency's 15 μg/L Action Level for lead and 100 μg/L Maximum Contamination Level Goal for total chromium. The DEG contamination of paracetamol (acetaminophen) containing products in 1995-1996 claimed the lives of 109 children and the 2000-2001 epidemic of ackee fruit poisoning resulted in 60 cases of

    There are a large number of ways in which the capture of carbon as carbon dioxide (CO{sub 2}) can be integrated into fossil fuel power stations, most being applicable for both gas and coal feedstocks. To add to the choice of technology is the question of whether an existing plant should be retrofitted for capture, or whether it is more attractive to build totally new. This miscellany of choices adds considerably to the commercial risk of investing in a large power station. An intermediate stage between the non-capture and full capture state would be advantageous in helping to determine the best way forward and hence reduce those risks. In recent years the term 'carbon capture ready' or 'capture ready' has been coined to describe such an intermediate stage plant and is now widely used. However a detailed and all-encompassing definition of this term has never been published. All fossil fuel consuming plant produce a carbon dioxide gas byproduct. There is a possibility of scrubbing it with an appropriate CO{sub 2} solvent. Hence it could be said that all fossil fuel plant is in a condition for removal of its CO{sub 2} effluent and therefore already in a 'capture ready' state. Evidently, the practical reality of solvent scrubbing could cost more than the rewards offered by such as the ETS (European Trading Scheme). In which case, it can be said that although the possibility exists of capturing CO{sub 2}, it is not a commercially viable option and therefore the plant could not be described as ready for CO{sub 2} capture. The boundary between a capture ready and a non-capture ready condition using this definition cannot be determined in an objective and therefore universally acceptable way and criteria must be found which are less onerous and less potentially contentious to assess. 16 refs., 2 annexes.

    In a previous publication [K. Gokhberg and L. S. Cederbaum, J. Phys. B 42, 231001 (2009)] we presented the interatomic Coulombic electron capture process--an efficient electron capture mechanism by atoms and ions in the presence of an environment. In the present work we derive and discuss the mechanism in detail. We demonstrate thereby that this mechanism belongs to a family of interatomic electron capture processes driven by electron correlation. In these processes the excess energy released in the capture event is transferred to the environment and used to ionize (or to excite) it. This family includes the processes where the capture is into the lowest or into an excited unoccupied orbital of an atom or ion and proceeds in step with the ionization (or excitation) of the environment, as well as the process where an intermediate autoionizing excited resonance state is formed in the capturing center which subsequently deexcites to a stable state transferring its excess energy to the environment. Detailed derivation of the asymptotic cross sections of these processes is presented. The derived expressions make clear that the environment assisted capture processes can be important for many systems. Illustrative examples are presented for a number of model systems for which the data needed to construct the various capture cross sections are available in the literature.

    Conclusion/significance: These findings demonstrate the value of high-resolution mapping for pinpointing locations most affected by cholera, and in the future could help prioritize the places in need of interventions such as improvement of sanitation and vaccination. The findings also describe spatio-temporal transmission patterns of the epidemic in a cholera-naïve country such as Haiti. By identifying transmission hubs, it is possible to target prevention strategies that, over time, could reduce transmission of the disease and eventually eliminate cholera in Haiti.

    To investigate the debate about South-South cooperation, we conducted an analysis of a course on the Management of Physical and Technological Resources in Health given in Haiti as part of a partnership between Fiocruz and the Brazilian and Haitian ministries of health with the aim of enabling the functioning of the units built by Brazil, contributing to the sustainability of the tripartite cooperation project. The course format - designing interventions to overcome real problems identified by the students - resulted in the development of eight intervention pre-projects geared towards overcoming management problems at the reference community hospitals built by Brazil in Haiti.

    The Multicenter Automatic Defibrillator Implantation Trial-Reduce Inappropriate therapy (MADIT-RIT) trial showed a significant reduction in inappropriate implantable cardioverter defibrillator (ICD) therapy in patients programmed to high-rate cut-off (Arm B) or delayed ventricular tachycardia therapy (Arm C), compared with conventional programming (Arm A). There is limited data on the effect of cardiac resynchronization therapy with a cardioverter defibrillator (CRT-D) on the effect of ICD programming. We aimed to elucidate the effect of CRT-D on ICD programming to reduce inappropriate ICD therapy in patients implanted with CRT-D or an ICD, enrolled in MADIT-RIT. The primary end point of this study was the first inappropriate ICD therapy. Secondary end points were inappropriate anti-tachycardia pacing and inappropriate ICD shock. The study enrolled 742 (49%) patients with an ICD and 757 (51%) patients with a CRT-D. Patients implanted with a CRT-D had 62% lower risk of inappropriate ICD therapy than those with an ICD only (hazard ratio [HR] =0.38, 95% confidence interval: 0.25-0.57; Pprogramming significantly reduced the risk of inappropriate ICD therapy compared with conventional ICD programming in ICD (HR=0.14 [B versus A]; HR=0.21 [C versus A]) and CRT-D patients (HR=0.15 [B versus A]; HR=0.23 [C versus A]; Pprogramming significantly reduces the risk of inappropriate ICD therapy in both ICD and CRT-D patients. http://clinicaltrials.gov; Unique identifier: NCT00947310. © 2016 American Heart Association, Inc.

    Recent calls for reform in healthcare training emphasize using competency-based curricula and information technology-empowered learning. Continuing Medical Education programs are essential in maintaining physician accreditation. Haitian physicians have expressed a lack access to these activities. The Haiti Medical Education Project works in alliance with Haitian medical leadership, faculty and students to support the Country's medical education system. We present the creation, delivery and evaluation of a competency-based continuing medical education curriculum for physicians in rural Haiti. Real time lectures from local and international institutions were teleconferenced to physicians in remote Haitian sites using VidyoConferencing™ technology. With American Academy of Family Physicians (AAFP) and College of Family Physicians Canada (CFPC) guidelines as references, a competency-derived syllabus was created for a Haitian continuing medical education program. The resulting educational goals were reviewed by a committee of Haitian and North American physician/medical education practitioners to reflect local needs. All authors reviewed lectures and then conferred to establish agreement on competencies presented for each lecture. Sixty-seven lectures were delivered. Human immunodeficiency virus/Acquired Immunodeficiency Syndrome, ophthalmologic, infectious diseases, renal and endocrine competencies were well-represented, with more than 50 % of the joint AAFP and CFPC recommended competencies outlined. Areas under-represented included allergy and immunology, cardiology, surgery, pain management, gastroenterology, neurology, pulmonology, men's health and rheumatology; these topics accounted for less than 25 % of AAFP/CFPC recommended competencies. Areas not covered included geriatrics, nutrition, occupational health and women's health. Within practice-based lectures, only disaster medicine, health promotion and information management were included, but only partially

    To assess the prevalence of disability and service needs in post-earthquake Haiti, and to compare the inclusion and living conditions of people with disabilities to those without disabilities. A population-based prevalence survey of disability was undertaken in 2012 in Port-au-Prince region, which was at the centre of the earthquake in 2010. Sixty clusters of 50 people aged 5 + years were selected with probability proportionate to size sampling and screened for disability (Washington Group short set questionnaire). A case-control study was undertaken, nested within the survey, matching cases to controls by age, gender and cluster. There was additional case finding to identify further children with disabilities. Information was collected on: socioeconomic status, education, livelihood, health, activities, participation and barriers. The prevalence of disability was 4.1% (3.4-4.7%) across 3132 eligible individuals. The earthquake was the second leading cause of disability. Disability was more common with increasing age, but unrelated to poverty. Large gaps existed in access of services for people with disabilities. Adults with disabilities were less likely to be literate or work and more likely to visit health services than adults without disabilities. Children with disabilities were less likely to be currently enrolled at school compared to controls. Children and adults with disabilities reported more activity limitations and participation restriction. Further focus is needed to improve inclusion of people with disabilities in post-earthquake Haiti to ensure that their rights are fulfilled. Almost one in six households in this region of Haiti included a person with a disability, and the earthquake was the second leading cause of disability. Fewer than half of people who reported needing medical rehabilitation had received this service. The leading reported barriers to the uptake of health services included financial constraints (50%) and difficulties with

    Full Text Available Abstract Background The seroprevalence of hepatitis C varies substantially between countries and geographic regions. A better understanding of the seroprevalence of this disease, and the risk factors associated with seropositive status, supply data for the development of screening programs and provide insight into the transmission of the disease. The purpose of this investigation was to determine the seroprevalence of hepatitis C and associated risk factors in an urban population in Haiti. Methods A prospective survey for hepatitis C antibodies was conducted among an urban outpatient population in Cap-Haïtien, Haiti, with a sample size of 500 subjects. An anonymous 12 question survey, with inquiries related to demographic characteristics and risk factors for HCV acquisition, was concomitantly administered with testing. These demographic and behavioral risk factors were correlated with HCV antibody status using univariate and multivariate tests. Results The prevalence of positive HCV antibody was 22/500 (4.4%. Subjects that were anti-HCV positive had an average of 7 ± 8.6 lifetime sexual partners, compared to average of 2.5 ± 3.5 lifetime sexual partners among HCV-negative subjects (p = 0.02. In a multiple logistic regression model, intravenous drug use (OR 3.7, 1.52–9.03 95% CI and number of sexual partners (OR 1.1, 1.04–1.20 95% CI were independently associated with a positive HCV antibody result. Conclusions A substantial number of subjects with HCV antibodies were detected in this population in Haiti. Further investigation into the correlation between the number of sexual partners and testing positive for hepatitis C antibodies is indicated.

    Many patients with HIV infection present for care late in the course of their disease, a factor which is associated with poor prognosis. Our objective was to identify factors associated with late presentation for HIV care among patients in central Haiti. Thirty-one HIV-positive adults, approximately 10% of the HIV-infected population followed at a central Haiti hospital, participated in this research study. A two-part research tool that included a structured questionnaire and an ethnographic life history interview was used to collect quantitative as well as qualitative data about demographic factors related to presentation for HIV care. Sixty-five percent of the patients in this study presented late for HIV care, as defined by CD4 cell count below 350 cells/mm3. Factors associated with late presentation included male sex, older age, patient belief that symptoms are not caused by a medical condition, greater distance from the medical clinic, lack of prior access to effective medical care, previous requirement to pay for medical care, and prior negative experience at local hospitals. Harsh poverty was a striking theme among all patients interviewed. Delays in presentation for HIV care in rural Haiti are linked to demographic, socioeconomic and structural factors, many of which are rooted in poverty. These data suggest that a multifaceted approach is needed to overcome barriers to early presentation for care. This approach might include poverty alleviation strategies; provision of effective, reliable and free medical care; patient outreach through community health workers and collaboration with traditional healers.

    Since the beginning of the cholera epidemic in Haiti 5 years ago, the prevalence of this deadly water-borne disease has fallen far below the initial rates registered during its explosive outset. However, cholera continues to cause extensive suffering and needless deaths across the country, particularly among the poor. The urgent need to eliminate transmission of cholera persists: compared to the same period in 2014, the first 4 months of 2015 saw three times the number of cholera cases. Drawing upon epidemiology, clinical work (and clinical knowledge), policy, ecology, and political economy, and informed by ethnographic data collected in a rural area of Haiti called Bocozel, this paper evaluates the progress of the nation's 10-year Plan for the Elimination of Cholera. Bocozel is a rice-producing region where most people live in extreme poverty. The irrigation network is decrepit, the land is prone to environmental shocks, fertilizer is not affordable, and the government's capacity to assist farmers is undermined by resource constraints. When peasants do have rice to sell, the price of domestically grown rice is twice that of US-imported rice. Canal water is not only used to irrigate thousands of acres of rice paddies and sustain livestock, but also to bathe, wash, and play, while water from wells, hand pumps, and the river is used for drinking, cooking, and bathing. Only one out of the three government-sponsored water treatment stations in the research area is still functional and utilized by those who can afford it. Latrines are scarce and often shared by up to 30 people; open defecation remains common. Structural vulnerabilities cut across all sectors - not just water, sanitation, health care, and education, but agriculture, environment, (global and local) commerce, transportation, and governance as well. These are among the hidden sicknesses that impede Haiti and its partners' capacity to eliminate cholera.

    Whole-genome sequencing is an important tool for understanding microbial evolution and identifying the emergence of functionally important variants over the course of epidemics. In October 2010, a severe cholera epidemic began in Haiti, with additional cases identified in the neighboring Dominican Republic. We used whole-genome approaches to sequence four Vibrio cholerae isolates from Haiti and the Dominican Republic and three additional V. cholerae isolates to a high depth of coverage (>2000x); four of the seven isolates were previously sequenced. Using these sequence data, we examined the effect of depth of coverage and sequencing platform on genome assembly and identification of sequence variants. We found that 50x coverage is sufficient to construct a whole-genome assembly and to accurately call most variants from 100 base pair paired-end sequencing reads. Phylogenetic analysis between the newly sequenced and thirty-three previously sequenced V. cholerae isolates indicates that the Haitian and Dominican Republic isolates are closest to strains from South Asia. The Haitian and Dominican Republic isolates form a tight cluster, with only four variants unique to individual isolates. These variants are located in the CTX region, the SXT region, and the core genome. Of the 126 mutations identified that separate the Haiti-Dominican Republic cluster from the V. cholerae reference strain (N16961), 73 are non-synonymous changes, and a number of these changes cluster in specific genes and pathways. Sequence variant analyses of V. cholerae isolates, including multiple isolates from the Haitian outbreak, identify coverage-specific and technology-specific effects on variant detection, and provide insight into genomic change and functional evolution during an epidemic.

    The Republic of Haiti is one of only several countries in the Western Hemisphere in which canine rabies is still endemic. Estimation methods have predicted that 130 human deaths occur per year, yet existing surveillance mechanisms have detected few of these rabies cases. Likewise, canine rabies surveillance capacity has had only limited capacity, detecting only two rabid dogs per year, on average. In 2013, Haiti initiated a community-based animal rabies surveillance program comprised of two components: active community bite investigation and passive animal rabies investigation. From January 2013 –December 2014, 778 rabies suspect animals were reported for investigation. Rabies was laboratory-confirmed in 70 animals (9%) and an additional 36 cases were identified based on clinical diagnosis (5%), representing an 18-fold increase in reporting of rabid animals compared to the three years before the program was implemented. Dogs were the most frequent rabid animal (90%). Testing and observation ruled out rabies in 61% of animals investigated. A total of 639 bite victims were reported to the program and an additional 364 bite victims who had not sought medical care were identified during the course of investigations. Only 31% of people with likely rabies exposures had initiated rabies post-exposure prophylaxis prior to the investigation. Rabies is a neglected disease in-part due to a lack of surveillance and understanding about the burden. The surveillance methods employed by this program established a much higher burden of canine rabies in Haiti than previously recognized. The active, community-based bite investigations identified numerous additional rabies exposures and bite victims were referred for appropriate medical care, averting potential human rabies deaths. The use of community-based rabies surveillance programs such as HARSP should be considered in canine rabies endemic countries. PMID:26600437

  4. Laboratory evaluation of immunochromatographic rapid diagnostic tests for cholera in Haiti.

    Full Text Available Rapid diagnostic tests (RDT for cholera are promising tools for detecting cholera in areas with limited laboratory infrastructure. However, evidence on the characteristics of the many available RDTs is scarce, and their use has been limited by suboptimal performance. We evaluated the performance characteristics of three cholera RDTs from Span Diagnostics, Artron Laboratories, and Standard Diagnostics in a regional laboratory in Haiti.We retrospectively reviewed records from May 2014 to October 2015 of a laboratory-based surveillance program for Vibrio cholerae at Hôpital Saint-Nicolas in Saint-Marc, Haiti. We compared the results of 511 Crystal VC, 129 Artron and 451 SD Bioline RDTs to bacterial culture as the gold standard. Of 905 cultures, 477 (52.7% were positive for V. cholerae O1, of which 27.7% were serotype Inaba. No cultures grew V. cholerae O139. Sensitivity and specificity of Crystal VC were 98.6% (95%CI: 96.5%-99.6% and 71.1% (95%CI: 64.7%-76.9%, respectively. Artron demonstrated a sensitivity of 98.6% (95%CI: 92.7%-100% and specificity of 69.1% (95%CI: 55.2%-80.9%. SD Bioline demonstrated a sensitivity of 81.1% (95%CI: 75.6%-85.8% and specificity of 92.8% (95%CI: 88.4%-95.9%. Crystal VC and Artron frequently showed false positive O139 bands, whereas none were seen with SD Bioline.There is significant variation in the performance of different cholera diagnostic RDTs. Artron and Crystal VC RDTs have high sensitivity and low specificity, while SD Bioline RDT has low to moderate sensitivity and high specificity when performed by laboratory technicians in Haiti. Study limitations included its retrospective design. The suboptimal characteristics of these tests limit their use as clinical point-of-care tests; however, they may be useful in outbreak response, surveillance, and research in resource-limited settings.

  5. Transpressional rupture of an unmapped fault during the 2010 Haiti earthquake

    On 12 January 2010, a Mw7.0 earthquake struck the Port-au-Prince region of Haiti. The disaster killed more than 200,000 people and caused an estimated $8 billion in damages, about 100% of the country?s gross domestic product. The earthquake was initially thought to have ruptured the Enriquillog-Plantain Garden fault of the southern peninsula of Haiti, which is one of two main strike-slip faults inferred to accommodate the 2cmyr -1 relative motion between the Caribbean and North American plates. Here we use global positioning system and radar interferometry measurements of ground motion to show that the earthquake involved a combination of horizontal and contractional slip, causing transpressional motion. This result is consistent with the long-term pattern of strain accumulation in Hispaniola. The unexpected contractional deformation caused by the earthquake and by the pattern of strain accumulation indicates present activity on faults other than the Enriquillog-Plantain Garden fault. We show that the earthquake instead ruptured an unmapped north-dipping fault, called the Léogâne fault. The Léogâne fault lies subparallel tog-but is different fromg-the Enriquillog-Plantain Garden fault. We suggest that the 2010 earthquake may have activated the southernmost front of the Haitian fold-and-thrust belt as it abuts against the Enriquillog-Plantain Garden fault. As the Enriquillog-Plantain Garden fault did not release any significant accumulated elastic strain, it remains a significant seismic threat for Haiti and for Port-au-Prince in particular. © 2010 Macmillan Publishers Limited.

    2014-08-01

    This study uses 2010-2011 Landsat Thematic Mapper (TM) imagery to estimate total forested area in Haiti. The thematic map was generated using radiometric normalization of digital numbers by a modified normalization method utilizing pseudo-invariant polygons (PIPs), followed by supervised classification of the mosaicked image using the Food and Agriculture Organization (FAO) of the United Nations Land Cover Classification System. Classification results were compared to other sources of land-cover data produced for similar years, with an emphasis on the statistics presented by the FAO. Three global land cover datasets (GLC2000, Globcover, 2009, and MODIS MCD12Q1), and a national-scale dataset (a land cover analysis by Haitian National Centre for Geospatial Information (CNIGS)) were reclassified and compared. According to our classification, approximately 32.3% of Haiti's total land area was tree covered in 2010-2011. This result was confirmed using an error-adjusted area estimator, which predicted a tree covered area of 32.4%. Standardization to the FAO's forest cover class definition reduces the amount of tree cover of our supervised classification to 29.4%. This result was greater than the reported FAO value of 4% and the value for the recoded GLC2000 dataset of 7.0%, but is comparable to values for three other recoded datasets: MCD12Q1 (21.1%), Globcover (2009) (26.9%), and CNIGS (19.5%). We propose that at coarse resolutions, the segmented and patchy nature of Haiti's forests resulted in a systematic underestimation of the extent of forest cover. It appears the best explanation for the significant difference between our results, FAO statistics, and compared datasets is the accuracy of the data sources and the resolution of the imagery used for land cover analyses. Analysis of recoded global datasets and results from this study suggest a strong linear relationship (R2 = 0.996 for tree cover) between spatial resolution and land cover estimates.

    To strengthen Haiti's primary health care (PHC) system, the country first piloted performance-based financing (PBF) in 1999 and subsequently expanded the approach to most internationally funded non-government organizations. PBF complements support (training and technical assistance). This study evaluates (a) the separate impact of PBF and international support on PHC's service delivery; (b) the combined impact of PBF and technical assistance on PHC's service delivery; and (c) the costs of PBF implementation in Haiti. To minimize the risk of facilities neglecting potential non-incentivized services, the incentivized indicators were randomly chosen at the end of each year. We obtained quantities of key services from four departments for 217 health centres (15 with PBF and 202 without) from 2008 through 2010, computed quarterly growth rates and analysed the results using a difference-in-differences approach by comparing the growth of incentivized and non-incentivized services between PBF and non-PBF facilities. To interpret the statistical analyses, we also interviewed staff in four facilities. Whereas international support added 39% to base costs of PHC, incentive payments added only 6%. Support alone increased the quantities of PHC services over 3 years by 35% (2.7%/quarter). However, support plus incentives increased these amounts by 87% over 3 years (5.7%/quarter) compared with facilities with neither input. Incentives alone was associated with a net 39% increase over this period, and more than doubled the growth of services (P < 0.05). Interview findings found no adverse impacts and, in fact, indicated beneficial impacts on quality. Incentives proved to be a relatively inexpensive, well accepted and very effective complement to support, suggesting that a small amount of money, strategically used, can substantially improve PHC. Haiti's experience, after more than a decade of use, indicates that incentives are an effective tool to strengthen PHC.

    In the case of IGCC power plants, carbon capture can be carried out before combustion. The carbon monoxide in the syngas is catalytically shifted to carbon dioxide and then captured in a standard gas absorption system. However, the insertion of a shift converter into an existing IGCC plant with no shift would mean a near total rebuild of the gasification waste heat recovery, gas treatment system and HRSG, with only the gasifier and gas turbine retaining most of their original features. To reduce the extent, cost and time taken for the revamping, the original plant could incorporate the shift, and the plant would then be operated without capture to advantage, and converted to capture mode of operation when commercially appropriate. This paper examines this concept of placing a shift converter into an IGCC plant before capture is required, and operating the same plant first without and then later with CO{sub 2} capture in a European context. The advantages and disadvantages of this 'capture ready' option are discussed. 6 refs., 2 figs., 4 tabs.

    In this study we documented unexpected moderate-to-severe iodine deficiency in Haitian schoolchildren although they live in a coastal community where presumably they have access to iodine-containing seafood. This fact combined with the lack of an iodized salt supply and endemic lymphatic filariasis makes community distribution of diethylcarbamazine-fortified, iodized salt an attractive strategy for elimination of lymphatic filariasis and iodine deficiency disorders in this area of Haiti. Combining lymphatic filariasis elimination with other public health interventions is one strategy to increase its public health benefit and maximize the impact of limited public health resources.

    In this study, we perform a case study on imagery from the Haiti earthquake that evaluates a novel object-based approach for characterizing earthquake induced surface effects of liquefaction against a traditional pixel based change technique. Our technique, which combines object-oriented change detection with discriminant/categorical functions, shows the power of distinguishing earthquake-induced surface effects from changes in buildings using the object properties concavity, convexity, orthogonality and rectangularity. Our results suggest that object-based analysis holds promise in automatically extracting earthquake-induced damages from high-resolution aerial/satellite imagery.

    This report provides further analysis of the feasibility of a waste-to-energy (WTE) facility in the area near Port-au-Prince, Haiti. NREL's previous analysis and reports identified anaerobic digestion (AD) as the optimal WTE technology at the facility. Building on the prior analyses, this report evaluates the conceptual financial and technical viability of implementing a combined waste management and electrical power production strategy by constructing a WTE facility at the existing Trutier waste site north of Port-au-Prince.

However, cholera continues to cause extensive suffering and needless deaths across the country, particularly among the poor. The urgent need to eliminate transmission of cholera persists: compared to the same period in 2014, the first 4 months of 2015 saw three times the number of cholera cases. Drawing upon epidemiology, clinical work (and clinical knowledge, policy, ecology, and political economy, and informed by ethnographic data collected in a rural area of Haiti called Bocozel, this paper evaluates the progress of the nation's 10-year Plan for the Elimination of Cholera. Bocozel is a rice-producing region where most people live in extreme poverty. The irrigation network is decrepit, the land is prone to environmental shocks, fertilizer is not affordable, and the government's capacity to assist farmers is undermined by resource constraints. When peasants do have rice to sell, the price of domestically grown rice is twice that of US-imported rice. Canal water is not only used to irrigate thousands of acres of rice paddies and sustain livestock, but also to bathe, wash, and play, while water from wells, hand pumps, and the river is used for drinking, cooking, and bathing.

    The experimental magnetic susceptibility, the temperature-independent component of the magnetic susceptibility, the magnetization, and the Curie constant have been measured for a number of specimens of glass from the K-T boundary found at Beloc, Haiti, and the results are compared with those of similar measurements of tektites. Because the Fe(3+)/Fe(2+) ratio is needed to calculate the magnetic parameters, Moessbauer spectroscopic measurements were also made. The data were consistent with the classification of the Beloc glasses as tektites.

    The North East Department is a resource-limited region of Haiti. Health care is provided by hospitals and community clinics, with no formal Emergency Medical System and undefined emergency services. As a paucity of information exists on available emergency services in the North East Department of Haiti, the objective of this study was to assess systematically the existing emergency care resources in the region. This cross-sectional observational study was carried out at all Ministry of Public Health and Population (MSPP)-affiliated hospitals in the North East Department and all clinics within the Fort Liberté district. A modified version of the World Health Organization (WHO) Tool for Situational Analysis to Assess Emergency and Essential Surgical Care and Generic Essential Emergency Equipment Lists were completed for each facility. Three MSPP hospitals and five clinics were assessed. Among hospitals, all had a designated emergency ward with 24 hour staffing by a medical doctor. All hospitals had electricity with backup generators and access to running water; however, none had potable water. All hospitals had x-ray and ultrasound capabilities. No computed tomography scanners existed in the region. Invasive airway equipment and associated medications were not present consistently in the hospitals' emergency care areas, but they were available in the operating rooms. Pulse oximetry was unavailable uniformly. One hospital had intermittently functioning defibrillation equipment, and two hospitals had epinephrine. Basic supplies for managing obstetrical and traumatic emergencies were available at all hospitals. Surgical services were accessible at two hospitals. No critical care services were available in the region. Clinics varied widely in terms of equipment availability. They uniformly had limited emergency medical equipment. The clinics also had inconsistent access to basic assessment tools (sphygmomanometers 20% and stethoscopes 60%). A protocol for transferring

    In Haiti, routine screening for Chlamydia trachomatis (CT), Neisseria gonorrhoeae (NG), and Trichomonas vaginalis (TV) among pregnant women is not conducted; yet these sexually transmitted infections (STIs) are associated with adverse birth and newborn health outcomes. We aimed to assess the acceptability and feasibility of screening and the prevalence of STIs among pregnant women in Port-au-Prince, Haiti. Pregnant women of at least 18 years of age who attend Haitian Study Group for Kaposi's sarcoma and Opportunistic Infections (GHESKIO) clinics in Port-au-Prince, Haiti provided self-collected vaginal swab specimens. Laboratory testing was done with Xpert® CT/NG and Xpert® TV. The results of this study showed that of the 322 pregnant women who visited GHESKIO for their regular scheduled appointments, 300 (93.2%) consented for CT, NG, and TV testing. Of those, 107 women (35.7%) tested positive for at least one STI. There were 42 (14.7%) cases of CT, 8 (2.8%) NG, and 83 (29.0%) TV infections. Most infections were treated - 122 of 133 (91.7%). In summary, we found that it was highly acceptable and feasible to implement CT, NG, and TV screening among pregnant women in Port-au-Prince, Haiti. We found high prevalence of STIs among pregnant women, which suggest that STI screening in this population may be warranted.

    The Enriquillog-Plantain Garden fault zone is recognized as one of the primary plate-bounding fault systems in Haiti. The strike-slip fault runs adjacent to the city of Port-au-Prince and was initially thought to be the source of the 12 January 2010, M w 7.0 earthquake. Haiti experienced significant earthquakes in 1751 and 1770 (refsA, 3, 4, 5), but the role of the Enriquillog-Plantain Garden fault zone in these earthquakes is poorly known. We use satellite imagery, aerial photography, light detection and ranging (LIDAR) and field investigations to document Quaternary activity on the Enriquillog-Plantain Garden fault. We report late Quaternary, left-lateral offsets of up to 160m, and a set of small offsets ranging from 1.3 to 3.3m that we associate with one of the eighteenth century earthquakes. The size of the small offsets implies that the historical earthquake was larger than M w 7.0, but probably smaller than M w 7.6. We found no significant surface rupture associated with the 2010 earthquake. The lack of surface rupture, coupled with other seismologic, geologic and geodetic observations, suggests that little, if any, accumulated strain was released on the Enriquillog-Plantain Garden fault in the 2010 earthquake. These results confirm that the Enriquillog-Plantain Garden fault remains a significant seismic hazard. ?? 2010 Macmillan Publishers Limited. All rights reserved.

    Full Text Available High neonatal mortality in Haiti is sustained by limited access to essential maternity services, particularly for Haiti’s rural population. We investigated the feasibility of a rural birthing home model to provide basic prenatal, delivery, and neonatal services for women with uncomplicated pregnancies while simultaneously providing triage and transport of women with pregnancy related complications. The model included consideration of the local context, including women’s perceptions of barriers to healthcare access and available resources to implement change. Evaluation methods included the performance of a baseline community census and collection of pregnancy histories from 791 women living in a defined area of rural Haiti. These retrospective data were compared with pregnancy outcome for 668 women subsequently receiving services at the birthing home. Of 764 reported most recent pregnancies in the baseline survey, 663(87% occurred at home with no assistance from skilled health staff. Of 668 women followed after opening of the birthing home, 514 (77% subsequently gave birth at the birthing home, 94 (14% were referred to a regional hospital for delivery, and only 60 (9% delivered at home or on the way to the birthing home. Other measures of clinical volume and patient satisfaction also indicated positive changes in health care seeking. After introduction of the birthing home, fewer neonates died than predicted by historical information or national statistics. The present experience points out the feasibility of a rural birthing home model to increase access to essential maternity services.

    We aimed to examine the relationship between exposure to the 2010 Haiti earthquake and pregnancy wantedness, interpregnancy interval, and birth weight. From the nationally representative Haiti 2012 Demographic and Health Survey, information on "size of child at birth" (too small or not) was available for 7280 singleton births in the previous 5 years, whereas information on birth weight was available for 1607 births. Pregnancy wantedness, short (earthquake and by level of damage. Multiple logistic regression and linear regression analyses were conducted. Post-earthquake births were less likely to be wanted and more likely to be born after a short interpregnancy interval. Earthquake exposure was associated with increased likelihood of a child being born too small: timing of birth (after earthquake vs. before earthquake, adjusted odds ratio [aOR]: 1.27, 95% confidence interval [CI]: 1.12-1.45), region (hardest-hit vs. rest of country; aOR: 1.43, 95% CI: 1.14- 1.80), and house damage (aOR: 1.27 95% CI: 1.02-1.58). Mean birth weight was 150 to 300 g lower in those exposed to the earthquake. Experience with the earthquake was associated with worse reproductive and birth outcomes, which underscores the need to provide reproductive health services as part of relief efforts.

    2011-04-01

    Full Text Available In this paper we study the energy of ULF electromagnetic waves that were recorded by the satellite DEMETER, during its passing over Haiti before and after a destructive earthquake. This earthquake occurred on 12 January 2010, at geographic Latitude 18.46° and Longitude 287.47°, with Magnitude 7.0 R. Specifically, we are focusing on the variations of energy of Ez-electric field component concerning a time period of 100 days before and 50 days after the strong earthquake. In order to study these variations, we have developed a novel method that can be divided in two stages: first we filter the signal, keeping only the ultra low frequencies and afterwards we eliminate its trend using techniques of Singular Spectrum Analysis (SSA, combined with a third-degree polynomial filter. As it is shown, a significant increase in energy is observed for the time interval of 30 days before the earthquake. This result clearly indicates that the change in the energy of ULF electromagnetic waves could be related to strong precursory earthquake phenomena. Moreover, changes in energy associated with strong aftershock activity were also observed 25 days after the earthquake. Finally, we present results concerning the comparison between changes in energy during night and day passes of the satellite over Haiti, which showed differences in the mean energy values, but similar results as far as the rate of the energy change is concerned.

  6. Control of Dog Mediated Human Rabies in Haiti: No Time to Spare.

    Directory of Open Access Journals (Sweden)

    Max F Millien

    Full Text Available The American region has pledged to eliminate dog-mediated human rabies by 2015. As part of these efforts, we describe the findings of a desk and field mission review of Haiti's rabies situation by the end of 2013. While government officials recognize the importance of dog-mediated rabies control, and the national rabies plan adequately contemplates the basic capacities to that effect, regular and sufficient implementation, for example, of dog vaccination, is hampered by limited funding. Compounding insufficient funding and human resources, official surveillance figures do not accurately reflect the risk to the population, as evidenced by the large number of rabid dogs detected by focalized and enhanced surveillance activities conducted by the Ministry of Agriculture, Natural Resources and Rural Development (MARNDR and the Health and Population Ministry (MSPP with the technical assistance of the United States Centers for Disease Control and Prevention. Although international support is common, either in the form of on-the-ground technical support or donations of immunobiologicals, it is not comprehensive. In addition, there is limited coordination with MARNDR/MSPP and with other actors at the strategic or operational level due to human resources limitations. Given these findings, the 2015 elimination goal in the region is compromised by the situation in Haiti where control of the disease is not yet in sight despite the best efforts of the resolute national officials. More importantly, dog-mediated rabies is still a threat to the Haitian population.

    2010-01-01

    This article analyzes the unintended consequences of humanitarian and development interventions in Haiti implemented to facilitate its postconflict transition following the period of military rule between 1991 and 1994. International and national governmental and nongovernmental initiatives to provide redress and healing to victims of human rights abuses from this period inadvertently contributed to the growth of a political economy of trauma. I argue that state-sponsored and non-state interventions aimed at truth seeking, acknowledging past ruptures, and reparations have intersected with the politics of local communities in ways that contribute to the commoditization of suffering in the political economy of trauma. The experience of a woman whose bodily integrity and personal sovereignty were violated by members of Haiti's terror apparatus demonstrates the presence of a terror economy. My witnessing of her interactions with the international and national humanitarian and development aid organizations that assisted her in the aftermath of violation revealed the contours of the compassion economy. It is the compassion economy that is the particular focus of this article. I evaluate whether rendering visible or audible the individual and collective suffering of the past truly aid processes of social reconstruction, democratization, and peace building, especially in states plagued with ongoing social, political, and economic insecurity. I argue that the forms of citizenship that these interventions engender are rarely permanent, especially in fragile or failed states, and may exacerbate the societal cleavages that gave rise to conflict.

  8. ART attrition and risk factors among Option B+ patients in Haiti: A retrospective cohort study.

    Full Text Available In October 2012, the Haitian Ministry of Health endorsed the "Option B+" strategy to eliminate mother-to-child transmission of HIV and achieve HIV epidemic control. The objective of this paper is to assess and identify risk factors for attrition from the national ART program among Option B+ patients in the 12 months after ART initiation.This retrospective cohort study included patients newly initiating ART from October 2012-August 2013 at 68 ART sites covering 45% of all newly enrolled ART patients in all regions of Haiti.With data from electronic medical records, we carried out descriptive analysis of sociodemographic, clinical, and pregnancy-related correlates of ART attrition, and used a modified Poisson regression approach to estimate relative risks in a multivariable model.There were 2,166 Option B+ patients who initiated ART, of whom 1,023 were not retained by 12 months (47.2%. One quarter (25.3% dropped out within 3 months of ART initiation. Protective factors included older age, more advanced HIV disease progression, and any adherence counseling prior to ART initiation, while risk factors included starting ART late in gestation, starting ART within 7 days of HIV testing, and using an atypical ART regimen.Our study demonstrates early ART attrition among Option B+ patients and contributes evidence on the characteristics of women who are most at risk of attrition in Haiti. Our findings highlight the importance of targeted strategies to support retention among Option B+ patients.

    Full Text Available The international response to Haiti's ongoing cholera outbreak has been multifaceted, including health education efforts by community health workers and the distribution of free water treatment products. Artibonite Department was the first region affected by the outbreak. Numerous organizations have been involved in cholera response efforts in Haiti with many focusing on efforts to improve water, sanitation, and hygiene (WASH. Multiple types of water treatment products have been distributed, creating the potential for confusion over correct dosage and water treatment methods. We utilized qualitative methods in Artibonite to determine the population's response to WASH messages, use and acceptability of water treatment products, and water treatment and sanitation knowledge, attitudes and practices at the household level. We conducted eighteen focus group discussions (FGDs: 17 FGDs were held with community members (nine among females, eight among males; one FGD was held with community health workers. Health messages related to WASH were well-retained, with reported improvements in hand-washing. Community health workers were identified as valued sources of health information. Most participants noted a paucity of water-treatment products. Sanitation, specifically the construction of latrines, was the most commonly identified need. Lack of funds was the primary reason given for not constructing a latrine. The construction and maintenance of potable water and sanitation services is needed to ensure a sustainable change.

    Recent studies report that Haitian women are concerned about unmet women's health issues. The Days for Girls (DfG) International program features women's health education and personal hygiene kits to ensure women understand the process of menstruation and sanitary hygiene practices. The aim was to train Haitian seamstresses to produce the DfG kits during an in-country workshop and investigate the perceived benefit of the DfG program in young women who used the DfG kits. Posttest only design was used to measure the effectiveness of DfG workshop and postsurvey to study perception of women using DfG kits. It was found that the workshop participants demonstrated an understanding of the DfG program (90% average). Forty-four young women (89.8%) who used the DfG hygiene kits for 2 months agreed that there is a need for feminine hygiene programs in Haiti and that the kits were easy to use and clean (97.1% and 92.1%, respectively). The DfG program could provide a cost-effective feminine hygiene program for Haiti and decrease waste from traditional hygiene products.

    Worldwide, there is a gap between the burden of mental distress and disorder and access to mental health care. This gap is particularly large in low- and middle-income countries (LMICs). After the 2010 earthquake in Haiti, the international health care organizations Partners in Health and Zanmi Lasante worked to expand local mental health services in rural Haiti. The aims of this study are to describe clinical characteristics of the patients served during a pilot project to deliver community-based psychiatric services in rural Haiti and to show how this experience complements the Mental Health Gap Action Programme ("mhGAP"), a tool developed by the World Health Organization to support mental health care delivery by nonspecialists in LMICs. The pilot was conducted in March 2011. A visiting psychiatrist traveled to rural Haiti and paired with local clinicians to evaluate patients and to support quality improvement practices in psychiatric care. Patients received a standard neuropsychiatric evaluation. mhGAP was an important clinical reference. To assess the experience, we conducted a retrospective chart review of outpatient encounters. Sixty-five patients presented with a wide range of common psychiatric, neurologic, and general medical conditions. Forty-nine of these patients (75%) reported primary problems subsumed by an mhGAP module. Fifteen patients (23%) reported headache as their chief complain, a condition that is not currently covered by mhGAP. Surprisingly, only 3 patients (5%), reported earthquake-related distress. Our clinical data reinforce the need for provision of standard psychiatric and neurologic services in LMICs. Such services ought to accompany interventions targeted specifically at disaster-related problems. Clinical situations falling outside existing mhGAP modules inspired the development of supplemental treatment protocols. These observations informed coordinated efforts at Zanmi Lasante to build a sustainable, integrated mental health system

    The ability to learn from both the mistakes and successes of the past is vital to assuring success in the future. Due to the close physical interaction between spacesuit systems and human beings as users, spacesuit technology and usage lends itself rather uniquely to the benefits realized from the skillful organization of historical information; its dissemination; the collection and identification of artifacts; and the education of those in the field. The National Aeronautics and Space Administration (NASA), other organizations and individuals have been performing United States (U.S.) Spacesuit Knowledge Capture since the beginning of space exploration. Avenues used to capture the knowledge have included publication of reports; conference presentations; specialized seminars; and classes usually given by veterans in the field. More recently the effort has been more concentrated and formalized whereby a new avenue of spacesuit knowledge capture has been added to the archives in which videotaping occurs engaging both current and retired specialists in the field presenting technical scope specifically for education and preservation of knowledge. With video archiving, all these avenues of learning can now be brought to life with the real experts presenting their wealth of knowledge on screen for future learners to enjoy. Scope and topics of U.S. spacesuit knowledge capture have included lessons learned in spacesuit technology, experience from the Gemini, Apollo, Skylab and Shuttle programs, hardware certification, design, development and other program components, spacesuit evolution and experience, failure analysis and resolution, and aspects of program management. Concurrently, U.S. spacesuit knowledge capture activities have progressed to a level where NASA, the National Air and Space Museum (NASM), Hamilton Sundstrand (HS) and the spacesuit community are now working together to provide a comprehensive closed-looped spacesuit knowledge capture system which includes

  13. Adiabatic capture and debunching

    2012-01-01

    In the study of beam preparation for the g-2 experiment, adiabatic debunching and adiabatic capture are revisited. The voltage programs for these adiabbatic processes are derived and their properties discussed. Comparison is made with some other form of adiabatic capture program. The muon g-2 experiment at Fermilab calls for intense proton bunches for the creation of muons. A booster batch of 84 bunches is injected into the Recycler Ring, where it is debunched and captured into 4 intense bunches with the 2.5-MHz rf. The experiment requires short bunches with total width less than 100 ns. The transport line from the Recycler to the muon-production target has a low momentum aperture of ∼ ±22 MeV. Thus each of the 4 intense proton bunches required to have an emittance less than ∼ 3.46 eVs. The incoming booster bunches have total emittance ∼ 8.4 eVs, or each one with an emittance ∼ 0.1 eVs. However, there is always emittance increase when the 84 booster bunches are debunched. There will be even larger emittance increase during adiabatic capture into the buckets of the 2.5-MHz rf. In addition, the incoming booster bunches may have emittances larger than 0.1 eVs. In this article, we will concentrate on the analysis of the adiabatic capture process with the intention of preserving the beam emittance as much as possible. At this moment, beam preparation experiment is being performed at the Main Injector. Since the Main Injector and the Recycler Ring have roughly the same lattice properties, we are referring to adiabatic capture in the Main Injector instead in our discussions.

    Our present knowledge of the nuclear muon capture reactions is surveyed. Starting from the formation of the muonic atom, various phenomena, having a bearing on the nuclear capture, are reviewed. The nuclear reactions are then studied from two angles-to learn about the basic muon+nucleon weak interaction process, and to obtain new insights on the nuclear dynamics. Future experimental prospects with the newer generation muon 'factories' are critically examined. Possible modification of the muon+nucleon weak interaction in complex nuclei remains the most important open problem in this field. (380 refs).

    Although previous studies have characterized the genetic structure of populations from Haiti and Jamaica using classical and autosomal STR polymorphisms, the patrilineal influences that are present in these countries have yet to be explored. To address this lacuna, the current study aims to investigate, for the first time, the potential impact of different ancestral sources, unique colonial histories, and distinct family structures on the paternal profile of both groups. According to previous reports examining populations from the Americas, island-specific demographic histories can greatly impact population structure, including various patterns of sex-biased gene flow. Also, given the contrasting autosomal profiles provided in our earlier study (Simms et al.: Am J Phys Anthropol 142 (2010) 49-66), we hypothesize that the degree and directionality of gene flow from Europeans, Africans, Amerindians, and East Asians are dissimilar in the two countries. To test this premise, 177 high-resolution Y-chromosome binary markers and 17 Y-STR loci were typed in Haiti (n = 123) and Jamaica (n = 159) and subsequently utilized for phylogenetic comparisons to available reference collections encompassing Africa, Europe, Asia (East and South), and the New World. Our results reveal that both studied populations exhibit a predominantly South-Saharan paternal component, with haplogroups A1b-V152, A3-M32, B2-M182, E1a-M33, E1b1a-M2, E2b-M98, and R1b2-V88 comprising 77.2% and 66.7% of the Haitian and Jamaican paternal gene pools, respectively. Yet, European derived chromosomes (i.e., haplogroups G2a*-P15, I-M258, R1b1b-M269, and T-M184) were detected at commensurate levels in Haiti (20.3%) and Jamaica (18.9%), whereas Y-haplogroups indicative of Chinese [O-M175 (3.8%)] and Indian [H-M69 (0.6%) and L-M20 (0.6%)] ancestry were restricted to Jamaica.

    Lymphatic filariasis (LF) and soil-transmitted helminths (STH) have been targeted since 2000 in Haiti, with a strong mass drug administration (MDA) program led by the Ministry of Public Health and Population and its collaborating international partners. By 2012, Haiti's neglected tropical disease (NTD) program had reached full national scale, and with such consistently good epidemiological coverage that it is now able to stop treatment for LF throughout almost all of the country. Essential to this success have been in the detail of how MDAs were implemented. These key programmatic elements included ensuring strong community awareness through an evidence-based, multi-channel communication and education campaign facilitated by voluntary drug distributors; strengthening community trust of the drug distributors by ensuring that respected community members were recruited and received appropriate training, supervision, identification, and motivation; enforcing a "directly observed treatment" strategy; providing easy access to treatment though numerous distribution posts and a strong drug supply chain; and ensuring quality data collection that was used to guide and inform MDA strategies. The evidence that these strategies were effective lies in both the high treatment coverage obtained- 100% geographical coverage reached in 2012, with almost all districts consistently achieving well above the epidemiological coverage targets of 65% for LF and 75% for STH-and the significant reduction in burden of infection- 45 communes having reached the target threshold for stopping treatment for LF. By taking advantage of sustained international financial and technical support, especially during the past eight years, Haiti's very successful MDA campaign resulted in steady progress toward LF elimination and development of a strong foundation for ongoing STH control. These efforts, as described, have not only helped establish the global portfolio of "best practices" for NTD control but

    Malaria is a public health concern in Haiti, although there are limited data on its burden and case management. National malaria guidelines updated in 2012 recommend treatment with chloroquine and primaquine. In December 2012, a nationally-representative cross-sectional survey of health facilities (HFs) was conducted to determine malaria prevalence among febrile outpatients and malaria case management quality at baseline before scale-up of diagnostics and case management training. Among all 833 HFs nationwide, 30 were selected randomly, in proportion to total HFs per region, for 2-day evaluations. Survey teams inventoried HF material and human resources. Outpatients of all ages were screened for temperature >37.5 °C or history of fever; those without severe symptoms were consented and enrolled. Providers evaluated and treated enrolled patients according to HF standards; the survey teams documented provider-ordered diagnostic tests and treatment decisions. Facility-based test results [microscopy and malaria rapid diagnostic tests (RDTs)] were collected from HF laboratories. Blood smears for gold-standard microscopy, and dried blood spots for polymerase chain reaction (PCR) were obtained. Malaria diagnostic capacity, defined as completing a test for an enrolled patient or having adequate resources for RDTs or microscopy, was present in 11 (37 %) HFs. Among 459 outpatients screened, 257 (56 %) were febrile, of which 193 (75 %) were eligible, and 153 (80 %) were enrolled. Among 39 patients with facility-level malaria test results available on the survey day, 11 (28 %) were positive, of whom 6 (55 %) were treated with an anti-malarial. Twenty-seven (95 %) of the 28 patients testing negative were not treated with an anti-malarial. Of 114 patients without test results available, 35 (31 %) were presumptively treated for malaria. Altogether, 42 patients were treated with an anti-malarial, one (2 %) according to Haiti's 2012 guidelines. Of 140 gold-standard smears, none

    Very few reliable clinical data about the use of radioimmunotherapy in aggressive B-cell lymphoma exist. Patients with aggressive B-cell lymphoma registered in the international RIT-Network were analysed with regard to prior treatment, response and side effects. The RIT-Network is a web-based registry that collects observational data from radioimmunotherapy-treated patients with malignant lymphoma across 13 countries. This analysis included 215 with aggressive B-cell lymphoma out of 232 patients registered in the RIT-Network. Histological subtypes were as follows: 190 diffuse large B-cell, 15 primary mediastinal, 9 anaplastic large cell, and 1 intravascular lymphoma. The median age of the patients was 62 years (range 17 - 88), with 27 % above the age of 70 years. Radioimmunotherapy was mainly used as consolidation after first-line or second-line chemotherapy (56.1 %), as part of third-line to eighth-line therapy for relapse (16.4 %), and in refractory disease (12.2 %). Grade IV neutropenia and thrombopenia and grade III anaemia were observed. The median time to recovery of blood count was 81 days (range 0 - 600 days). The overall response rate was 63.3 %. The complete response rate was 76.4 % in patients treated as part of first-line therapy, and 44.3 % in patients with relapse. Mean overall survival in first-line therapy patients was 32.7 months and 14.0 months in patients with relapse or refractory disease, respectively. Most patients with aggressive B-cell lymphoma in the RIT-Network received radioimmunotherapy as consolidation after first-line therapy with excellent complete remission and overall survival rates compared to published data. In relapsed aggressive B-cell lymphoma, radioimmunotherapy is a safe and feasible treatment leading to satisfactory response rates with acceptable toxicity. (orig.)

    Highlights: • A point reactor kinetics code coupled with thermal hydraulics of plate type fuel is developed. • This code is applicable for two phase flow of coolant. • Safety analysis of IAEA benchmark reactor core is carried out. • Results agree well with the results available in literature. - Abstract: A point reactor kinetics code SAC-RIT, acronym of Safety Analysis Code for Reactivity Initiated Transient, coupled with thermal hydraulics of two phase coolant flow for plate type fuel, is developed to calculate reactivity initiated transient analysis of nuclear research and test reactors. Point kinetics equations are solved by fourth order Runge Kutta method. Reactivity feedback effect is included into the code. Solution of kinetics equations gives neutronic power and it is then fed into a thermal hydraulic code where mass, momentum and thermal energy conservation equations are solved by explicit finite difference method to find out fuel, clad and coolant temperatures during transients. In this code, all possible flow regimes including laminar flow, transient flow and turbulent flow have been covered. Various heat transfer coefficients suitable for single liquid, sub-cooled boiling, saturation boiling, film boiling and single vapor phases are incorporated in the thermal hydraulic code

    Haiti, a Caribbean country of 10.5 million people, is estimated to have the highest burden of canine-mediated human rabies deaths in the Western Hemisphere, and one of the highest rates of human rabies deaths in the world. Haiti is also the poorest country in the Western Hemisphere and has numerous economic and health priorities that compete for rabies-control resources. As a result, primary rabies-control actions, including canine vaccination programs, surveillance systems for human and animal rabies, and appropriate postbite treatment, have not been fully implemented at a national scale. After the 2010 earthquake that further hindered the development of public health program infrastructure and services, the U.S. Centers for Disease Control and Prevention worked with the Ministry of Public Health and Population and key health development partners (including the Pan-American Health Organization) to provide technical expertise and funding for general disease surveillance systems, laboratory capacity, and selected disease control programs; including rabies. In 2011, a cross-ministerial rabies consortium was convened with participation from multiple international rabies experts to develop a strategy for successful rabies control in Haiti. The consortium focused on seven pillars: 1) enhancement of laboratory diagnostic capacity, 2) development of comprehensive animal surveillance system, 3) development of comprehensive human rabies surveillance system, 4) educational outreach, 5) sustainable human rabies biologics supply, 6) achievement of sustained canine vaccination rates of ≥ 70%, and 7) finalization of a national rabies control strategy. From 2010 until 2015, Haiti has seen improvements in the program infrastructure for canine rabies control. The greatest improvements were seen in the area of animal rabies surveillance, in support of which an internationally recognized rabies laboratory was developed thereby leading to an 18-fold increase in the detection of

    Using a set of statistical methods and HIV mathematical models applied on nationally representative Demographic and Health Survey data, we characterized HIV serodiscordancy patterns and HIV transmission dynamics in stable couples (SCs) in four countries: Cambodia, the Dominican Republic, Haiti, and India. The majority of SCs affected by HIV were serodiscordant, and about a third of HIV-infected persons had uninfected partners. Overall, nearly two-thirds of HIV infections occurred in individuals in SCs, but only about half of these infections were due to transmissions within serodiscordant couples. The majority of HIV incidence in the population occurred through extra-partner encounters in SCs. There is similarity in HIV epidemiology in SCs between these countries and countries in sub-Saharan Africa, despite the difference in scale of epidemics. It appears that HIV epidemiology in SCs may share similar patterns globally, possibly because it is a natural 'spillover' effect of HIV dynamics in high-risk populations.

    The International Commission on Radiological Protection and the international organizations that co-sponsored the International Basic Safety Standards for the Protection against Ionization Radiation and for the Safety of Radiation Sources (BSS) - among them PAHO and WHO - recommended the use of investigation levels to provide guidance for medical exposures. In this work, entrance surface doses for several common diagnostic radiology procedure have been determined from exposure rate measurements and patient technique factors in seven 'World Health Imaging System - Radiography' (WHIS-RAD) units, installed in public health services facilities of the Republic of Haiti. The results show the entrance surface doses below the guidance levels published in the BSS. Concomitant image quality measurements performed, however, indicate serious artifacts in the film processing, calling for the need of additional training of the technologists. (author)

    Managing the stock and supply of medication is essential for the provision of health care, especially in resource poor areas of the world. We have developed an innovative, web-based stock management system to support nine clinics in rural Haiti. Building on our experience with a web-based EMR system for our HIV patients, we developed a comprehensive stock tracking system that is modeled on the appearance of standardized WHO stock cards. The system allows pharmacy staff at all clinics to enter stock levels and also to request drugs and track shipments. Use of the system over the last 2 years has increased rapidly and we now track 450 products supporting care for 1.78 million patient visits annually. Over the last year drug stockouts have fallen from 2.6% to 1.1% and 97% of stock requests delivered were shipped within 1 day. We are now setting up this system in our clinics in rural Rwanda.

    2010-01-01

    The solid waste management industry in Haiti is comprised of a formal and an informal sector. Many basic activities in the solid waste management sector are being carried out within the context of profound poverty, which exposes the failure of the socioeconomic and political system to provide sufficient job opportunities for the urban population. This paper examines the involvement of workers in the solid waste management industry in Greater Port-au-Prince and the implications for livelihood strategies. The findings revealed that the Greater Port-au-Prince solid waste management system is very inclusive with respect to age, while highly segregated with regard to gender. In terms of earning capacity, the results showed that workers hired by the State agencies were the most economically vulnerable group as more than 50% of them fell below the official nominal minimum wage. This paper calls for better salary scales and work compensation for the solid waste workers.

    The K/T boundary sequence is exposed in uplifted carbonate sediments of the southwest peninsula of Haiti. It is found at 15 localities within the Beloc formation, a sequence of limestone and marls interpreted as a monoclinal nappe structure thrust to the north. This tectonic deformation has affected the K/T boundary deposit to varying degrees. In some cases the less competent K/T deposit has acted as a slip plane leading to extensive shearing of the boundary layer, as well as duplication of the section. The presence of glassy tektites, shocked quartz, and an Ir anomaly directly link the deposit to a bolide impact. Stratigraphic and sedimentological features of the tripartite sequence indicate that it was formed by deposition from ballistic fallout of coarse tektites, emplacement of particle gravity flows and fine grained fallout of widely dispersed impact ejecta.

    Natural disasters in populated areas may result in massive casualties and extensive destruction of infrastructure. Humanitarian aid delegations may have to cope with the complicated issue of patient prioritization under conditions of severe resource scarcity. A triage model, consisting of five principles, is proposed for the prioritization of patients, and it is argued that rational and reasonable agents would agree upon them. The Israel Defense Force's humanitarian mission to Haiti following the 2010 earthquake serves as a case study for the various considerations taken into account when designing the ethical-clinical policy of field hospitals. The discussion focuses on three applications: the decision to include an intensive care unit, the decision to include obstetrics and neonatal units, and the treatment policy for compound fractures. © 2017 John Wiley & Sons Ltd.

    Sharma, Sandeep; Kumari, Nitu

    In this paper, a nonlinear deterministic model is proposed with a saturated treatment function. The expression of the basic reproduction number for the proposed model was obtained. The global dynamics of the proposed model was studied using the basic reproduction number and theory of dynamical systems. It is observed that proposed model exhibits backward bifurcation as multiple endemic equilibrium points exist when R0 cholera in the community. We also obtain a unique endemic equilibria when R0 > 1. The global stability of unique endemic equilibria is performed using the geometric approach. An extensive numerical study is performed to support our analytical results. Finally, we investigate two major cholera outbreaks, Zimbabwe (2008-09) and Haiti (2010), with the help of the present study.

    Cholera, previously unrecognized in Haiti, spread through the country in the fall of 2010. An analysis was performed to understand the epidemiological characteristics, clinical management, and risk factors for disease severity in a population seen at the GHESKIO Cholera Treatment Center in Port-au-Prince. A comprehensive review of the medical records of patients admitted during the period of October 28, 2010-July 10, 2011 was conducted. Disease severity on admission was directly correlated with older age, more prolonged length of stay, and presentation during the two epidemic waves seen in the observation period. Although there was a high seroprevalence of human immunodeficiency virus (HIV), severity of cholera was not greater with HIV infection. This study documents the correlation of cholera waves with rainfall and its reduction in settings with improved sanitary conditions and potable water when newly introduced cholera affects all ages equally so that interventions must be directed throughout the population.

    During disasters, partnerships between public and nonprofit organizations are vital to provide fast relief to affected communities. In this article, we develop a process model to support a performance evaluation of such intersectoral partnerships. The model includes input factors, organizational structures, outputs and the long-term outcomes of public–nonprofit partnerships. These factors derive from theory and a systematic literature review of emergency, public, nonprofit, and network research. To adapt the model to a disaster context, we conducted a case study that examines public and nonprofit organizations that partnered during the 2010 Haiti earthquake. The case study results show that communication, trust, and experience are the most important partnership inputs; the most prevalent governance structure of public–nonprofit partnerships is a lead organization network. Time and quality measures should be considered to assess partnership outputs, and community, network, and organizational actor perspectives must be taken into account when evaluating partnership outcomes.

    Months after a 7.0 magnitude earthquake hit Port-au-Prince, Haiti, over one million remain homeless and living in spontaneous internally displaced person (IDP) camps. Billions of dollars from aid organizations and government agencies have been pledged toward the relief effort, yet many basic human needs, including food, shelter, and sanitation, continue to be unmet. The Sphere Project, "Humanitarian Charter and Minimum Standards in Disaster Response," identifies the minimum standards to be attained in disaster response. From a human rights perspective and utilizing key indicators from the Sphere Project as benchmarks, this article reports on an assessment of the living conditions approximately 12 weeks after the earthquake in Parc Jean Marie Vincent, a spontaneous IDP camp in Port-au-Prince. A stratified random sample of households in the camp, proportionate to the number of families living in each sector, was selected. Interview questions were designed to serve as "key indicators" for the Sphere Project minimum standards. A total of 486 interviews were completed, representing approximately 5% of households in each of the five sectors of the camp. Our assessment identified the relative achievements and shortcomings in the provision of relief services in Parc Jean Marie Vincent. At the time of this survey, the Sphere Project minimum standards for access to health care and quantity of water per person per day were being met. Food, shelter, sanitation, and security were below minimum accepted standard and of major concern. The formal assessment reported here was completed by September 2010, and is necessarily limited to conditions in Haiti before the cholera outbreak in October. Copyright © 2010 Cullen and Ivers.

    Mathematical models can provide key insights into the course of an ongoing epidemic, potentially aiding real-time emergency management in allocating health care resources and possibly anticipating the impact of alternative interventions. Spatially explicit models of waterborne disease are made routinely possible by widespread data mapping of hydrology, road network, population distribution, and sanitation. Here, we study the ex-post reliability of predictions of the ongoing Haiti cholera outbreak. Our model consists of a set of dynamical equations (SIR-like, i.e. subdivided into the compartments of Susceptible, Infected and Recovered individuals) describing a connected network of human communities where the infection results from the exposure to excess concentrations of pathogens in the water, which are, in turn, driven by hydrologic transport through waterways and by mobility of susceptible and infected individuals. Following the evidence of a clear correlation between rainfall events and cholera resurgence, we test a new mechanism explicitly accounting for rainfall as a driver of enhanced disease transmission by washout of open-air defecation sites or cesspool overflows. A general model for Haitian epidemic cholera and the related uncertainty is thus proposed and applied to the dataset of reported cases now available. The model allows us to draw predictions on longer-term epidemic cholera in Haiti from multi-season Monte Carlo runs, carried out up to January 2014 by using a multivariate Poisson rainfall generator, with parameters varying in space and time. Lessons learned and open issues are discussed and placed in perspective. We conclude that, despite differences in methods that can be tested through model-guided field validation, mathematical modeling of large-scale outbreaks emerges as an essential component of future cholera epidemic control.

    Master health facility lists (MHFLs) are gaining attention as a standards-based means to uniquely identify health facilities and to link facility-level data. The ability to reliably communicate information about specific health facilities can support an array of health system functions, such as routine reporting and emergency response operations. MHFLs support the alignment of donor-supported health information systems with county-owned systems. Recent World Health Organization draft guidance promotes the utility of MHFLs and outlines a process for list development and governance. Although the potential benefits of MHFLs are numerous and may seem obvious, there are few documented cases of MHFL construction and use. The international response to the 2010 Haiti earthquake provides an example of how governments, nongovernmental organizations, and others can collaborate within a framework of standards to build a more complete and accurate list of health facilities. Prior to the earthquake, the Haitian Ministry of Health (Ministère de la Santé Publique et de la Population [MSPP]) maintained a list of public-sector health facilities but lacked information on privately managed facilities. Following the earthquake, the MSPP worked with a multinational group to expand the completeness and accuracy of the list of health facilities, including information on post-quake operational status. This list later proved useful in the response to the cholera epidemic and is now incorporated into the MSPP's routine health information system. Haiti's experience demonstrates the utility of MHFL formation and use in crisis as well as in the routine function of the health information system.

    This paper presents clinical data on 41 patients (29 male and 12 female) from Haiti who presented with acquired immunedeficiency syndrome (AIDS). Their mean age was 32 years (range 17-61 years). 4 of thes cases were homosexual or bisexual; none was an illicit drug user or a hemophiliac. In addition, 3 of the female patients had sexual contact with a male partner with AIDS. 4 patients had received blood transfusions before their illness. The most prominent clinical symptom in this series was chronic diarrhea of 2-33 months' duration, which occurrred in 39 patients (95%). Also reporte were marked weight loss (95%), fatigue (95%), prolonger fever (90%), and nodular or maculopapular skin lesions (54%). Opportunistic infections in this series included oroesophageal candidiasis (88%) and intestinal cryptosporidiosis (31%). Tuberculosis developed in 22% of patients. Immunologic evaluation revealed profoundly depressed T-helper cells and an inverted T-helper/T-suppressor cell ratio. Biologic markers included elevated alpha-1 thymosin and beta-2 microglobulin levels, elevated immune complexes, and the presence of acid-labile interferon. Of interest were differences in the clinical expression of AIDS between this series and cases in the US. The Haitian data suggest a higher incidencs of female cases,a predominance of gastrointestinal symptoms rather than respiratory symptoms and lymphadenopathy, a frequent association with tuberculosis, and a relatively low incidence of Kaposi's sarcoma or P. carinii pneumonia compared to the situation in the US. As in the US, where most AIDS cases are concentrated in New York and California, most AIDS cases in Haiti are found in residents of Port-au-Prince and Carrefour, which are centers for male and female prostitution.

    Full Text Available OBJECTIVE: To assess factors associated with utilization of maternal health services (MHS among women giving birth in Haiti from 2007 - 2012. METHODS: Observational data derived from the 2012 Haiti Mortality, Morbidity and Service Use Survey are analyzed. Multilevel analytic methods are used to assess factors associated with use of antenatal services and skilled birth attendance (SBA. RESULTS: The strongest adjusted predictors include child's birth rank, household poverty, and community media saturation. The odds of obtaining four antenatal care visits decrease by 53% (odds ratio (OR = 0.47; 95% confidence interval (CI: 0.37-0.57 with high birth rank and by 37% (OR = 0.63; 95% CI: 0.51-0.78 with household poverty, and increase by 38% (OR = 1.38; 95% CI: 1.01-1.88 with high community media saturation.

Use of antenatal services is strongly associated with SBA (OR = 2.20; 95% CI: 1.85-2.61. Significant clustering of use of MHS exists at the community level. CONCLUSIONS: Factors associated with use of MHS operate at multiple levels. Efforts to promote such services should identify and pay special attention to the needs of multiparous and uneducated women, address the distance-decay phenomenon, and improve access for the poor. Community mobilization efforts designed to change norms hindering the use of MHS are also relevant.

    Oral cholera vaccination was used as part of cholera control in Haiti, but the vaccine does not provide complete protection. We conducted secondary data analyses of a vaccine effectiveness study in Haiti to evaluate risk factors for cholera among cholera vaccine recipients. Individuals vaccinated against cholera that presented with acute watery diarrhea and had a stool sample positive for Vibrio cholerae O1 were included as cases. Up to four vaccinated individuals who did not present for treatment of diarrhea were included as controls for each case, and matched by location of residence, enrollment time, and age. We evaluated sociodemographic characteristics and risk factors for cholera. Univariable and multivariable logistic regression were performed to identify risk factors for cholera among vaccinees. Thirty-three vaccine recipients with culture-confirmed cholera were included as cases. One-hundred-and-seventeen of their matched controls reported receiving vaccine and were included as controls. In a multivariable analysis, self-reporting use of branded household water disinfection products as a means of treating water (adjusted relative risk [aRR] = 44.3, 95% confidence interval [CI] = 4.19-468.05, P = 0.002), and reporting having a latrine as the main household toilet (aRR = 4.22, 95% CI = 1.23-14.43, P = 0.02), were independent risk factors for cholera. Self-reporting always treating water (aRR = 0.09, 95% CI = 0.01-0.57, P = 0.01) was associated with protection against cholera. The field effectiveness of water, sanitation, and hygiene interventions used in combination with cholera vaccination in cholera control should be measured and monitored over time to identify and remediate shortcomings, and ensure successful impact on disease control.

    Expanding coverage of primary healthcare services such as antenatal care and vaccinations is a global health priority; however, many Haitians do not utilize these services. One reason may be that the population avoids low quality health facilities. We examined how facility infrastructure and the quality of primary health care service delivery were associated with community utilization of primary health care services in Haiti. We constructed two composite measures of quality for all Haitian facilities using the 2013 Service Provision Assessment survey. We geographically linked population clusters from the Demographic and Health Surveys to nearby facilities offering primary health care services. We assessed the cross-sectional association between quality and utilization of four primary care services: antenatal care, postnatal care, vaccinations and sick child care, as well as one more complex service: facility delivery. Facilities performed poorly on both measures of quality, scoring 0.55 and 0.58 out of 1 on infrastructure and service delivery quality respectively. In rural areas, utilization of several primary cares services (antenatal care, postnatal care, and vaccination) was associated with both infrastructure and quality of service delivery, with stronger associations for service delivery. Facility delivery was associated with infrastructure quality, and there was no association for sick child care. In urban areas, care utilization was not associated with either quality measure. Poor quality of care may deter utilization of beneficial primary health care services in rural areas of Haiti. Improving health service quality may offer an opportunity not only to improve health outcomes for patients, but also to expand coverage of key primary health care services.

    Haiti has been the locus of a number of large and damaging historical earthquakes. The recent 12 January 2010 Mw 7.0 earthquake affected cities that were largely unprepared, which resulted in tremendous losses. It was initially assumed that the earthquake ruptured the Enriquillo Plantain Garden fault (EPGF), a major active structure in southern Haiti, known from geodetic measurements and its geomorphic expression to be capable of producing M 7 or larger earthquakes. Global Positioning Systems (GPS) and Interferometric Synthetic Aperture Radar (InSAR) data, however, showed that the event ruptured a previously unmapped fault, the Léogâne fault, a north‐dipping oblique transpressional fault located immediately north of the EPGF. Following the earthquake, several groups installed temporary seismic stations to record aftershocks, including ocean‐bottom seismometers on either side of the EPGF. We use data from the complete set of stations deployed after the event, on land and offshore, to relocate all aftershocks from 10 February to 24 June 2010, determine a 1D regional crustal velocity model, and calculate focal mechanisms. The aftershock locations from the combined dataset clearly delineate the Léogâne fault, with a geometry close to that inferred from geodetic data. Its strike and dip closely agree with the global centroid moment tensor solution of the mainshock but with a steeper dip than inferred from previous finite fault inversions. The aftershocks also delineate a structure with shallower southward dip offshore and to the west of the rupture zone, which could indicate triggered seismicity on the offshore Trois Baies reverse fault. We use first‐motion focal mechanisms to clarify the relationship of the fault geometry to the triggered aftershocks.

    Gadolinium neutron capture therapy makes use of photons and electrons produced by nuclear reactions between gadolinium and lower-energy neutrons which occur within the tumor. The results of our studies have shown that its radiation effect is mostly of low LET and that the electrons are the significant component in the over-all dose. The dose from gadolinium neutron capture reactions does not seem to increase in proportion to the gadolinium concentration, and the Gd-157 concentration of about 100 μg/ml appears most optimal for therapy. Close contact between gadolinium and the cell is not necessarily required for cell inactivation, however, the effect of electrons released from intracellular gadolinium may be significant. Experimental studies on tumor-bearing mice and rabbits have shown that this is a very promising modality though further improvements in gadolinium delivery to tumors are needed. (author)

    Mansonella ozzardi (Nematoda: Onchocercidae) is a little studied filarial nematode. This human parasite, transmitted by two families of dipteran vectors, biting midges (most of them members of the genus Culicoides) and blackflies (genus Simulium), is endemic to the Neotropical regions of the New World. With a patchy geographical distribution from southern Mexico to north-western Argentina, human infection with M. ozzardi is highly prevalent in some of the Caribbean islands, along riverine communities in the Amazon Basin, and on both sides of the border between Bolivia and Argentina. Studies conducted in Haiti between 1974 and 1984 allowed the first complete description of the adult worm and permitted clarification of the taxonomic position of this filarial species. This paper reports the known geographical distribution of M. ozzardi in Neotropical regions of the Americas, and focuses on the current situation in Haiti where this filariasis remains a completely neglected public health problem.

    Using calculated stress changes to faults surrounding the January 12, 2010, rupture on the Enriquillo Fault, and the current (January 12 to 26, 2010) aftershock productivity, scientists from the U.S. Geological Survey (USGS), Woods Hole Oceanographic Institution (WHOI), and Disaster Prevention Research Institute, Kyoto University (DPRI) have made rough estimates of the chance of a magnitude (Mw)=7 earthquake occurring during January 27 to February 22, 2010, in Haiti. The probability of such a quake on the Port-au-Prince section of the Enriquillo Fault is about 2 percent, and the probability for the section to the west of the January 12, 2010, rupture is about 1 percent. The stress changes on the Septentrional Fault in northern Haiti are much smaller, although positive.

    Full Text Available Cervical cancer remains a significant cause of morbidity and mortality for women in developing countries, despite the fact that inexpensive, simple and effective screening methods are available. Visual inspection of the cervix with acetic acid (VIA can be used as part of a “screen and treat” program to identify precancerous lesions for cryotherapy treatment. This case report details how the VIA screening test was incorporated into the care of a patient presenting to a maternal health clinic in Thomonde, Haiti which was staffed by doctors and medical students from Emory University School of Medicine in collaboration with Haiti Medishare. As demonstrated here, the VIA test requires minimal materials, can be efficiently incorporated into a physical exams, provides immediate results, and is easily demonstrated to and performed by local healthcare providers. The straightforward and sensitive VIA technique is an ideal cervical cancer screening method for resource poor areas.

    This study aimed to evaluate the clinical and epidemiologic profile of congestive heart failure at the principal free-care hospital in Haiti. Cardiovascular disease represents the most prevalent cause of admissions to the medical service of the University Hospital of the State of Haiti. No previous study has examined the demographics of congestive heart failure in urban Haiti. Two hundred forty-seven patients presented to the inpatient service between May 2011 and May 2013. Evaluation included history and physical, CBC, renal/metabolic profile, serum glucose, anti-HIV antibody, ECG, chest radiograph and echocardiogram. Treatment included angiotensin converting enzyme inhibitors, furosemide and spironolactone, carvedilol, digoxin and anticoagulation. Women (62.4%) outnumbered men; patients were relatively young (mean age 50.1) and from the lowest socio-economic levels of the population. Nearly all (98.8%) presented with NYHA III-IV status, with correspondingly high mortality (23.3%). Echocardiography showed 73% dilated cardiomyopathy; 83% showed moderate to severe LV systolic dysfunction (mean EF 36.5 +/- 15%) and 17% preserved LV systolic function. The three principal etiologies were dilated cardiomyopathy (29%) hypertensive cardiomyopathy (27%) and peripartum cardiomyopathy (20%). Ischemic cardiomyopathy was rare (3.4%). At 27 months follow-up, 76.7% of the patients were alive and well. Among those who died, mean survival time was 113 days. Readmission carried a poor prognosis. This congestive heart failure study from Haiti shows an unusually high proportion of young women, primarily due to peripartum cardiomyopathy. Ischemic cardiomyopathy is rare, as in Africa. Further study is warranted to address the particular problem of the high frequency of peripartum cardiomyopathy in this population. Copyright © 2016 Elsevier Inc. All rights reserved.

    The primary aim was to examine the association of socio-economic factors and diet with overweight (including obesity) among school-aged children in Haiti. The secondary aim was to describe food availability and the physical activity built environment in participating schools. This cross-sectional study examined baseline data from the intervention Mamba study assessing the effectiveness of a fortified peanut butter paste in school-aged children. Logistic regression modelling was used to test hypothesized factors in association with overweight status. Six primary schools in Cap-Haitien, the second largest city in Haiti. Children (n 968) aged 3-13 years, in good health and enrolled in a participating school for the 2012/13 school year. Child age (adjusted OR (AOR); 95 % CI=0·25; 0·12, 0·56), child age squared (1·08; 1·03, 1·13), always purchasing food at school (3·52; 1·12, 11·08), mother's BMI (1·10; 1·04, 1·16) and household ownership of a bicycle (0·28; 0·11, 0·71) were significantly associated with overweight (likelihood ratio=36, Poverweight children in the binary analysis (P=0·033) and improved the fit of the model. Schools had limited time and space for physical activity and foods sold by vendors were predominantly high in sugar or fat. To our knowledge the present study is the first to examine the covariates of childhood overweight or describe school food availability and physical activity built environments in Haiti. Further research is necessary to identify intervention targets and feasible, cost-effective approaches for prevention of obesity in Haiti children.

    Background Introduction of Vibrio cholerae to Haiti during the deployment of United Nations (UN) peacekeepers in 2010 resulted in one of the largest cholera epidemics of the modern era. Following the outbreak, a UN-commissioned independent panel recommended three pre-deployment intervention strategies to minimize the risk of cholera introduction in future peacekeeping operations: screening for V. cholerae carriage, administering prophylactic antimicrobial chemotherapies, or immunizing with oral cholera vaccines. However, uncertainty regarding the effectiveness of these approaches has forestalled their implementation by the UN. We assessed how the interventions would have impacted the likelihood of the Haiti cholera epidemic. Methods and Findings We developed a stochastic model for cholera importation and transmission, fitted to reported cases during the first weeks of the 2010 outbreak in Haiti. Using this model, we estimated that diagnostic screening reduces the probability of cases occurring by 82% (95% credible interval: 75%, 85%); however, false-positive test outcomes may hamper this approach. Antimicrobial chemoprophylaxis at time of departure and oral cholera vaccination reduce the probability of cases by 50% (41%, 57%) and by up to 61% (58%, 63%), respectively. Chemoprophylaxis beginning 1 wk before departure confers a 91% (78%, 96%) reduction independently, and up to a 98% reduction (94%, 99%) if coupled with vaccination. These results are not sensitive to assumptions about the background cholera incidence rate in the endemic troop-sending country. Further research is needed to (1) validate the sensitivity and specificity of rapid test approaches for detecting asymptomatic carriage, (2) compare prophylactic efficacy across antimicrobial regimens, and (3) quantify the impact of oral cholera vaccine on transmission from asymptomatic carriers. Conclusions Screening, chemoprophylaxis, and vaccination are all effective strategies to prevent cholera introduction

    To perform the first prospective survey of neurologic and neurosurgical emergency department (ED) admissions in Haiti. Data of all ED admissions at 3 Haitian hospitals for 90 consecutive days per site were collected prospectively. Patients who were given a diagnosis of a neurologic or neurosurgical disorder by the ED physician were entered in a deidentified database including demographics, presenting symptoms, brain imaging (when available), requests for neurosurgical consultation, and outcome. Of the 7628 patients admitted to the ED during this study, 1243 patients had a neurologic disorder, yielding an ED-based neurologic disease prevalence of 16%. The 3 most common neurologic diseases were cerebrovascular disease (31%), neurotrauma (28%), and altered mental status (12%). Neurosurgical pathologies represented 19% of all neurologic admissions with a combined ED-based disease prevalence of 3%. Mortality rate was 9%. The most common neurosurgical disease was neurotrauma (87%), caused by motor vehicle accidents (59%), falls (20%), and assault (17%). Neurosurgical procedures were performed in 14 of 208 patients with a mortality rate of 33%. This prospective survey represents the first study of neurosurgical or neurologic disease patterns in Haiti. The results suggest specific disease priorities for this population that can guide efforts to improve Haitian health care and conduct more comprehensive epidemiologic studies in Haiti.

    This study examines the links between migration and sexual and reproductive health among rural-to-urban migrant youth in Haiti. It evaluates behavioural, knowledge and attitudinal components from the perspective of three competing explanations for migrants' behaviours: adaptation, disruption and selection. Discrete-time event history analysis is employed to compare these hypotheses using Haiti Demographic and Health Survey data (N=1215 adolescent girls, N=829 adolescent boys). Multi-level models are used to compare changes in knowledge and attitudes in individuals using data from the Haiti Youth Transitions Study (N=223). The findings reveal that disruption is the most plausible explanation for the timing of migration and first sex among girls. However, contrary to the assumption that migrant youth risk experiencing first sex earlier, girls are less likely to experience first sex near the time they migrate, and rural-to-urban migrant boys may experience first sex at later ages. The high aspirations of migrant youth provide a likely explanation for these findings. Furthermore, male migrants accumulate less protective knowledge, which is consistent with the disruption hypothesis, and migrants endorse premarital sex similarly to non-migrants. Sexual and reproductive health curricula should be adapted to the unique needs of migrant youth, and youth should be targeted before they migrate.

    A catastrophic Mw7 earthquake ruptured on 12 January 2010 on a complex fault system near Port-au-Prince, Haiti. Offshore rupture is suggested by aftershock locations and marine geophysics studies, but its extent remains difficult to define using geodetic and teleseismic observations. Here we perform the multitaper multiple signal classification (MUSIC) analysis, a high-resolution array technique, at regional distance with recordings from the Venezuela National Seismic Network to resolve high-frequency (about 0.4 Hz) aspects of the earthquake process. Our results indicate westward rupture with two subevents, roughly 35 km apart. In comparison, a lower-frequency finite source inversion with fault geometry based on new geologic and aftershock data shows two slip patches with centroids 21 km apart. Apparent source time functions from USArray further constrain the intersubevent time delay, implying a rupture speed of 3.3 km/s. The tips of the slip zones coincide with subevents imaged by backprojections. The different subevent locations found by backprojection and source inversion suggest spatial complementarity between high- and low-frequency source radiation consistent with high-frequency radiation originating from rupture arrest phases at the edges of main slip areas. The centroid moment tensor (CMT) solution and a geodetic-only inversion have similar moment, indicating most of the moment released is captured by geodetic observations and no additional rupture is required beyond where it is imaged in our preferred model. Our results demonstrate the contribution of backprojections of regional seismic array data for earthquakes down to M ≈ 7, especially when incomplete coverage of seismic and geodetic data implies large uncertainties in source inversions.

    Full Text Available The paper explores the activities conducted as part of WhoLoDancE: Whole Body Interaction Learning for Dance Education which is an EU-funded Horizon 2020 project. In particular, we discuss the motion capture sessions that took place at Motek, Amsterdam as well as the dancers’ experience of being captured and watching themselves or others as varying visual representations through the HoloLens. HoloLens is Microsoft’s first holographic computer that you wear as you would a pair of glasses. The study embraced four dance genres: Ballet, Contemporary, Flamenco and Greek Folk dance. We are specifically interested in the kinesthetic and emotional engagement with the moving body and what new corporeal awareness may be experienced. Positioning the moving, dancing body as fundamental to technological advancements, we discuss the importance of considering the dancer’s experience in the real and virtual space. Some of the artists involved in the project have offered their experiences, which are included, and they form the basis of the discussion. In addition, we discuss the affect of immersive environments, how these environments expand reality and what effect (emotionally and otherwise that has on the body. The research reveals insights into relationships between emotion, movement and technology and what new sensorial knowledge this evokes for the dancer.

    The Synovectomy by Neutron capture has as purpose the treatment of the rheumatoid arthritis, illness which at present does not have a definitive curing. This therapy requires a neutron source for irradiating the articulation affected. The energy spectra and the intensity of these neutrons are fundamental since these neutrons induce nuclear reactions of capture with Boron-10 inside the articulation and the freely energy of these reactions is transferred at the productive tissue of synovial liquid, annihilating it. In this work it is presented the neutron spectra results obtained with moderator packings of spherical geometry which contains in its center a Pu 239 Be source. The calculations were realized through Monte Carlo method. The moderators assayed were light water, heavy water base and the both combination of them. The spectra obtained, the average energy, the neutron total number by neutron emitted by source, the thermal neutron percentage and the dose equivalent allow us to suggest that the moderator packing more adequate is what has a light water thickness 0.5 cm (radius 2 cm) and 24.5 cm heavy water (radius 26.5 cm).

    In this study we compare the different Google Earth imagery (GEI) available before and after the 01-12-2010 earthquake of Haiti and carry out a detailed analysis of the superficial seismic-related geological deformations in the following sites: 1) the capital Port-Au-Prince and other cities (Carrefour and Gresslier); 2) the mountainous area of the Massif de la Selle which is transected by the "Enriquillo-Plaintain-Garden" (EPG) interplate boundary-fault (that supposedly triggered the seism); 3) some of the most important river channels and their corresponding deltas (Momanche, Grise and Frorse). The initial results of our researches were published in March 2010 in a special web page created by the scientific community to try to mitigate the devastating effects of this catastrophe (http://supersites.earthobservations.org/haiti.php). Six types of superficial geological deformations triggered by the seismic event have been identified with the GEI: liquefaction structures, chaotic rupture zones, coastal and domal uplifts, river-delta turnovers, faults/ruptures and landslides. Potential geological hazards triggered by the Haiti earthquake include landslides, inundations, reactivation of active tectonic elements (e.g., fractures), river-delta turnovers, etc. We analyzed again the GEI after the rain period and, as expected, most of the geological deformations that we initially identified had been erased and/or modified by the water washout or buried by the sediments. In this sense the GEI constitutes an invaluable instrument in the analysis of seismic geological hazards: we still have the possibility to compare all the images before and after the seism that are recorded in its useful "time tool". These are in fact the only witnesses of most of the geological deformations triggered by the Haiti earthquake that remain stored in the virtual archives of the GEI. In fact a field trip to the area today would be useless as most of these structures have disappeared. We will show

    Phylodynamic analysis of genome-wide single-nucleotide polymorphism (SNP) data is a powerful tool to investigate underlying evolutionary processes of bacterial epidemics. The method was applied to investigate a collection of 65 clinical and environmental isolates of Vibrio cholerae from Haiti collected between 2010 and 2012. Characterization of isolates recovered from environmental samples identified a total of four toxigenic V. cholerae O1 isolates, four non-O1/O139 isolates, and a novel nontoxigenic V. cholerae O1 isolate with the classical tcpA gene. Phylogenies of strains were inferred from genome-wide SNPs using coalescent-based demographic models within a Bayesian framework. A close phylogenetic relationship between clinical and environmental toxigenic V. cholerae O1 strains was observed. As cholera spread throughout Haiti between October 2010 and August 2012, the population size initially increased and then fluctuated over time. Selection analysis along internal branches of the phylogeny showed a steady accumulation of synonymous substitutions and a progressive increase of nonsynonymous substitutions over time, suggesting diversification likely was driven by positive selection. Short-term accumulation of nonsynonymous substitutions driven by selection may have significant implications for virulence, transmission dynamics, and even vaccine efficacy. Cholera, a dehydrating diarrheal disease caused by toxigenic strains of the bacterium Vibrio cholerae, emerged in 2010 in Haiti, a country where there were no available records on cholera over the past 100 years. While devastating in terms of morbidity and mortality, the outbreak provided a unique opportunity to study the evolutionary dynamics of V. cholerae and its environmental presence. The present study expands on previous work and provides an in-depth phylodynamic analysis inferred from genome-wide single nucleotide polymorphisms of clinical and environmental strains from dispersed geographic settings in

    Cholera is caused by Vibrio cholerae, and is transmitted through fecal-oral contact. Infection occurs after the ingestion of the bacteria and is usually asymptomatic. In a minority of cases, it causes acute diarrhea and vomiting, which can lead to potentially fatal severe dehydration, especially in the absence of appropriate medical care. Immunity occurs after infection and typically lasts 6-36 months. Cholera is responsible for outbreaks in many African and Asian developing countries, and caused localised and episodic epidemics in South America until the early 1990s. Haiti, despite its low socioeconomic status and poor sanitation, had never reported cholera before the recent outbreak that started in October 2010, with over 720,000 cases and over 8700 deaths (Case fatality rate: 1.2%) through 8 december 2014. So far, this outbreak has seen 3 epidemic peaks, and it is expected that cholera will remain in Haiti for some time. To trace the path of the early epidemic and to identify hot spots and potential transmission hubs during peaks, we examined the spatial distribution of cholera patients during the first two peaks in Artibonite, the second-most populous department of Haiti. We extracted the geographic origin of 84,000 patients treated in local health facilities between October 2010 and December 2011 and mapped these addresses to 63 rural communal sections and 9 urban cities. Spatial and cluster analysis showed that during the first peak, cholera spread along the Artibonite River and the main roads, and sub-communal attack rates ranged from 0.1% to 10.7%. During the second peak, remote mountain areas were most affected, although sometimes to very different degrees even in closely neighboring locations. Sub-communal attack rates during the second peak ranged from 0.2% to 13.7%. The relative risks at the sub-communal level during the second phase showed an inverse pattern compared to the first phase. These findings demonstrate the value of high-resolution mapping

    Background Haiti's cholera epidemic has been devastating partly due to underlying weak infrastructure and limited clean water and sanitation. A comprehensive approach to cholera control is crucial, yet some have argued that oral cholera vaccination (OCV) might result in reduced hygiene practice among recipients. We evaluated the impact of an OCV campaign on knowledge and health practice in rural Haiti. Methodology/Principal Findings We administered baseline surveys on knowledge and practice relevant to cholera and waterborne disease to every 10th household during a census in rural Haiti in February 2012 (N = 811). An OCV campaign occurred from May–June 2012 after which we administered identical surveys to 518 households randomly chosen from the same region in September 2012. We compared responses pre- and post-OCV campaign. Post-vaccination, there was improved knowledge with significant increase in percentage of respondents with ≥3 correct responses on cholera transmission mechanisms (odds ratio[OR] 1.91; 95% confidence interval[CI] 1.52–2.40), preventive methods (OR 1.83; 95% CI 1.46–2.30), and water treatment modalities (OR 2.75; 95% CI 2.16–3.50). Relative to pre-vaccination, participants were more likely post-OCV to report always treating water (OR 1.62; 95% CI 1.28–2.05). Respondents were also more likely to report hand washing with soap and water >4 times daily post-vaccine (OR 1.30; 95% CI 1.03–1.64). Knowledge of treating water as a cholera prevention measure was associated with practice of always treating water (OR 1.47; 95% CI 1.14–1.89). Post-vaccination, knowledge was associated with frequent hand washing (OR 2.47; 95% CI 1.35–4.51). Conclusion An OCV campaign in rural Haiti was associated with significant improvement in cholera knowledge and practices related to waterborne disease. OCV can be part of comprehensive cholera control and reinforce, not detract from, other control efforts in Haiti. PMID:24278498

    Full Text Available Background The United Nations (UN Millennium Developmental Goal #4 addresses needed reductions in childhood mortality. A major cause of death in Haitian children is malnutrition and starvation. Objectives Our primary objective was to identify population characteristics of children living in rural Haiti that may place them at higher risk of malnutrition than others. Armed with this knowledge, community health workers can recognize and attribute resources to those most in need. We will also examine the overall nutrition status in the population of interest and compare to the UN Millennium Goal statistics. Study design The study cohort consisted of 103 children under the age of 5 years, who were consecutively seen in a rural medical clinic from 4 communities in the Thomazeau region of Haiti over a 7-day time period. Families were asked the following five questions: (1 How many children do you have? (2 What is the birth order of this child (1st, 2nd, etc.? (3 What is the distance between your house and clean water? (4 Do you obtain water for your family? (5 What was the highest grade you finished in school? The medical team recorded each child’s gender, age, height, weight, household size, when the last meal was eaten, and last time protein was ingested. Nutritional status was assessed using World Health Organization growth standards. The data was then analyzed to determine each child’s level of malnutrition as measured by weight-for-height Z-score (number of standard deviations [SD] below reference value, percentage of malnutrition for all children surveyed, and whether correlations existed between malnutrition level and number of siblings, household size, or location. Trends were defined as associations significant at p3 SD below normal Z-score. Using a parsimonious multivariable regression model to compare family structure factors to anthropomorphic variables, multiparity was positively associated with Z- score (p<0.05, suggesting that later

    Haiti is considered particularly vulnerable to the effects of climate change, but directly linking climate change to health effects is limited by the lack of robust data and the multiple determinants of health. Worsening storms and rising temperatures in this rugged country with high poverty is likely to adversely affect economic activity, population growth and other determinants of health. For the past two years, the Univ. of Washington has supported the public hospital in the department of Grand'Anse. Grand'Anse, a relatively contained region in SW Haiti with an area of 11,912 km2, is predominantly rural with a population of 350,000 and is bounded to the south by peaks up to 2,347 m. Grand'Anse would serve as an excellent site to assess the interface between climate change and health. The Demographic and Health Survey (DHS) shows health status is low relative to other countries. Estimates of climate change for Jeremie, the largest city in Grand'Anse, predict the mean monthly temperature will increase from 26.1 to 27.3 oC while mean monthly rainfall will decrease from 80.5 to 73.5 mm over the next 60 years. The potential impact of these changes ranges from threatening food security to greater mortality. Use of available secondary data such as indicators of climate change and DHS health status are not likely to offer sufficient resolution to detect positive or negative impacts of climate change on health. How might a mixed methods approach incorporating secondary data and quantitative and qualitative survey data on climate, economic activity, health and determinants of health address the hypothesis: Climate change does not adversely affect health? For example, in Haiti most women deliver at home. Maternal mortality is high at 350 deaths/100,000 deliveries. This compares to deliveries in facilities where the median rate is less than 100/100,000. Thus, maternal mortality is closely linked to access to health care in this rugged mountainous country.

    The 2010 Haiti earthquake and Pakistan floods were similar in their massive human impact. Although the specific events were very different, the humanitarian response to disasters is supposed to achieve the same ends. This paper contrasts the disaster effects and aims to contrast the medium-term response. In January 2011, similarly structured population-based surveys were carried out in the most affected areas using stratified cluster designs (80×20 in Pakistan and 60×20 in Haiti) with probability proportional to size sampling. Displacement persisted in Haiti and Pakistan at 53% and 39% of households, respectively. In Pakistan, 95% of households reported damage to their homes and loss of income or livelihoods, and in Haiti, the rates were 93% and 85%, respectively. Frequency of displacement, and income or livelihood loss, were significantly higher in Pakistan, whereas disaster-related deaths or injuries were significantly more prevalent in Haiti. Given the rise in disaster frequency and costs, and the volatility of humanitarian funding streams as a result of the recent global financial crisis, it is increasingly important to measure the impact of humanitarian response against the goal of a return to normalcy.

    This report summarizes research conducted through the Sandia National Laboratories Robust Automated Knowledge Capture Laboratory Directed Research and Development project. The objective of this project was to advance scientific understanding of the influence of individual cognitive attributes on decision making. The project has developed a quantitative model known as RumRunner that has proven effective in predicting the propensity of an individual to shift strategies on the basis of task and experience related parameters. Three separate studies are described which have validated the basic RumRunner model. This work provides a basis for better understanding human decision making in high consequent national security applications, and in particular, the individual characteristics that underlie adaptive thinking.

    Capturing the Daylight Dividend conducted activities to build market demand for daylight as a means of improving indoor environmental quality, overcoming technological barriers to effective daylighting, and informing and assisting state and regional market transformation and resource acquisition program implementation efforts. The program clarified the benefits of daylight by examining whole building systems energy interactions between windows, lighting, heating, and air conditioning in daylit buildings, and daylighting's effect on the human circadian system and productivity. The project undertook work to advance photosensors, dimming systems, and ballasts, and provided technical training in specifying and operating daylighting controls in buildings. Future daylighting work is recommended in metric development, technology development, testing, training, education, and outreach.

    Full Text Available Viral load (VL assessment is the preferred method for diagnosing and confirming virologic failure for patients on antiretroviral therapy (ART. We conducted a retrospective cross-sectional study to evaluate the virologic suppression rate among patients on ART for ≥6 months in five hospitals around Port-au-Prince, Haiti.Plasma VL was measured and patients with VL <1,000 copies/mL were defined as virologically suppressed. A second VL test was performed within at least six months of the first test. Factors associated with virologic suppression were analyzed using logistic regression models accounting for site-level clustering using complex survey procedures.Data were analyzed for 2,313 patients on ART for six months or longer between July 2013 and February 2015. Among them, 1,563 (67.6% achieved virologic suppression at the first VL test. A second VL test was performed within at least six months for 718 (31.0% of the patients. Of the 459 patients with an initial HIV-1 RNA <1,000 copies/mL who had a second VL performed, 394 (85.8% maintained virologic suppression. Virologic suppression was negatively associated with male gender (adjusted odds ratio [aOR]: 0.80, 95% CI: 0.74-0.0.86, 23 to 35 months on ART (aOR:0.72[0.54-0.96], baseline CD4 counts of 201-500 cells/mm3 and 200 cells/mm3 or lower (aORs: 0.77 [0.62-0.95] and 0.80 [0.66-0.98], respectively, poor adherence (aOR: 0.69 [0.59-0.81], and TB co-infection (aOR: 0.73 [0.55-0.97].This study showed that over two-thirds of the patients in this evaluation achieved virologic suppression after ≥ six months on ART and the majority of them remained suppressed. These results reinforce the importance of expanding access to HIV-1 viral load testing in Haiti for monitoring ART outcomes.

    Full Text Available Zika virus (ZIKV, first isolated in Uganda in 1947, is currently spreading rapidly through South America and the Caribbean. In Brazil, infection has been linked with microcephaly and other serious complications, leading to declaration of a public health emergency of international concern; however, there currently are only limited data on the virus (and its possible sources and manifestations in the Caribbean.From May, 2014-February, 2015, in conjunction with studies of chikungunya (CHIKV and dengue (DENV virus infections, blood samples were collected from children in the Gressier/Leogane region of Haiti who presented to a school clinic with undifferentiated febrile illness. Samples were initially screened by RT-PCR for CHIKV and DENV, with samples negative in these assays further screened by viral culture.Of 177 samples screened, three were positive for ZIKV, confirmed by viral sequencing; DENV-1 was also identified in culture from one of the three positive case patients. Patients were from two different schools and 3 different towns, with all three cases occurring within a single week, consistent with the occurrence of an outbreak in the region. Phylogenetic analysis of known full genome viral sequences demonstrated a close relationship with ZIKV from Brazil; additional analysis of the NS5 gene, for which more sequences are currently available, showed the Haitian strains clustering within a monophyletic clade distinct from Brazilian, Puerto Rican and Guatemalan sequences, with all part of a larger clade including isolates from Easter Island. Phylogeography also clarified that at least three major African sub-lineages exist, and confirmed that the South American epidemic is most likely to have originated from an initial ZIKV introduction from French Polynesia into Easter Island, and then to the remainder of the Americas.ZIKV epidemics in South America, as well as in Africa, show complex dissemination patterns. The virus appears to have been

    To evaluate four household water treatment (HWT) products currently seeking approval for distribution in Haiti, through the application of a recently-developed national HWT product certification process. Four chemical treatment products were evaluated against the certification process validation stage by verifying international product certifications confirming treatment efficacy and reviewing laboratory efficacy data against WHO HWT microbiological performance targets; and against the approval stage by confirming product composition, evaluating treated water chemical content against national and international drinking water quality guidelines and reviewing packaging for dosing ability and usage directions in Creole. None of the four evaluated products fulfilled validation or approval stage requirements. None was certified by an international agency as efficacious for drinking water treatment, and none had data demonstrating its ability to meet WHO HWT performance targets. All product sample compositions differed from labelled composition by >20%, and no packaging included complete usage directions in Creole.

    Health care delivery is particularly problematic in fragile states often connected with increased incidence of communicable diseases, among them tuberculosis. This article draws upon experiences in tuberculosis control in four fragile states from which four lessons learned were derived. A structured inventory to extract common themes specific for TB control in fragile states was conducted among twelve providers of technical assistance who have worked in fragile states. The themes were applied to the TB control programs of Afghanistan, DR Congo, Haiti and Somalia during the years 2000-2006. Case notifications and treatment outcomes have increased in all four countries since 2003 (treatment success rates 81-90%). Access to care and case detection however have remained insufficient (case detection rates 39-62%); There are four lessons learned: 1. TB control programs can function in fragile states. 2. National program leadership and stewardship are essential for quality and sustained TB control. 3. Partnerships with non-governmental providers are vital for continuous service delivery; 4. TB control programs in fragile states require consistent donor support. Despite challenges in management, coordination, security, logistics and funding, TB control programs can function in fragile states, but face considerable problems in access to diagnosis and treatment and therefore case detection.

    Initial 87 Sr/ 86 Sr ratios have been determined for a representative suite of Upper Cretaceous granodiorites and associated rocks from the Above Rocks composite stock in central Jamaica and the Terre-Neuve pluton in northwestern Haiti. The average initial 87 Sr/ 86 Sr ratio for seven samples of the Terre-Neuve intrusion is 0.7036, with a range of 0.7026-0.7047. For two samples of the Above Rocks the initial ratios are 0.7033 and 0.7034. A third sample from this intrusive has an initial ratio of 0.7084, which is tentatively attributed to contamination. The initial 87 Sr/ 86 Sr ratios indicate that neither ancient sialic crust nor sediments carried down a Benioff zone can be the primary source of the granodioritic magma. K/Rb ratios for these rocks range from 178 to 247, which are much lower than the average values (>= 1000) for tholeiitic basalts. It is concluded that the magmas originated primarily by melting of downthrust oceanic crust or adjacent mantle material. (Auth.)

    To examine the nutrition-related factors associated with motor and language development among young children living in a poor urban area of Haiti. Children aged 6-11 months (n = 583) were enrolled and followed monthly for one year. World Health Organization motor developmental milestones and vowel and consonant counts were assessed. Longitudinal regression models were applied to assess the association of anthropometric, dietary intake, infectious disease morbidity and socio-economic and demographic factors on developmental outcomes. At baseline, 9.4% were stunted or length-for-age Z score < -2, and 30.2% were mild-to-moderately stunted or length-for-age Z score < -1. Stunting status was significantly associated with motor and phonetic language acquisition at each time point during infancy. Several nutrition factors significantly predicted earlier achievement of motor and language development outcomes in longitudinal models: child anthropometry; breastfeeding and complementary feeding frequencies; dietary diversity; egg and oil intake; and reduced infectious disease morbidities. Increases in the length-for-age Z score significantly predicted all motor and language outcomes and yielded the best fit models compared to other anthropometric indicators (p < 0.001). Child development interventions may be enhanced by incorporating nutrition strategies such as improved diet quality, breastfeeding promotion and diarrhoeal disease mitigation. ©2016 Foundation Acta Paediatrica.

    A number of studies have examined emotional and belief responses following a disaster, yet there has been limited comparative analysis of responses to disasters in different places. This paper reviews the results of 366 questionnaires that evaluated key emotional and belief concepts in Haiti after the earthquake on 12 January 2010 (n=212) and in Indonesia after the earthquake in Yogyakarta on 27 May 2006 (n=154). The results indicate significant differences between the responses in the two settings, particularly in relation to feelings of impunity, self-blame for the disaster, regret about pre-earthquake behaviour, and a sense of justice in the world. Furthermore, the impacts of age, education, and gender on responses also were different in the two case study sites. Overall, the results suggest that understanding the cultural, religious, and social contexts of different disaster locales is important in comprehending the emotions and beliefs that manifest themselves in the wake of a major disaster. © 2017 The Author(s).

    Globally, two-thirds of child deaths could be prevented by increased provision of health interventions such as vaccines, micronutrient supplements, and water purification tablets. We report the results from a randomized controlled trial in Haiti during 2012 that tested whether microfinance institutions-which reach 200 million households worldwide-can effectively deliver health products. These institutions provide loans to underserved entrepreneurs, primarily poor women in rural areas. In the intervention group, micronutrient powders to improve the nutrition of young children were distributed at regularly occurring microfinance meetings by a trained borrower. In both the control and the intervention groups, nurses led seminars on nutrition and extended breastfeeding during microfinance meetings. At three-month follow-up, the mean difference in hemoglobin concentration between children in the intervention group and those in the control group was 0.28 grams per deciliter (g/dL)-with a subsample of younger children (under two years of age) showing greater relative improvement (0.46 g/dL)-and the odds ratio for children in the intervention group meeting the diagnostic criteria for anemia was 0.64. The results are similar to those of previous studies that evaluated micronutrient powder distribution through dedicated health institutions. Our findings suggest that microfinance institutions are a promising platform for the large-scale delivery of health products in low-income countries.

    Full Text Available This is a report on the experience of implementing a mental health program in a maternity hospital and three mobile clinics in the city of Port-au-Prince. We started by listening to the difficulties faced by the national teams in their daily routines at the hospital and what they expected of a mental health program. The program was planned in a way to contemplate the perceived needs of the hospital teams as well as those of the target population, pre and post-natal women, within a systemic perspective. Thus the program covered the following aspects: training with the hospital team on communication and helping relationships, a series of speeches on mental health at the hospital, psychological treatment of the patients through counseling sessions, involvement of partners and families being assisted, support groups for peri-natal mourning, men's groups with the future fathers, psychoeducation in the mobile clinics, a survey of the social network in the city, psycho-social assistance and the introduction of relaxation strategies at the hospital. We concluded that in the context of a humanitarian crisis, as in the case of Haiti, a mental health program should contemplate different levels of need and take into consideration that health care professionals are also subject to the context of social stress. At the same time, the involvement of hospital teams in the process is fundamental to the success of the program.

    Engagement in sexual activity among Haitian youth is increasing. The present cross-sectional study examined the independent correlates of sexual risk behaviors among 200 (108 male/92 female) 13-18 year-old adolescents in Port-au-Prince, Haiti using face-to-face interviews. The majority (60.0 %) had engaged in sexual intercourse. Multivariate modeling found males to be 3.52 times more likely to have had sex, 5.42 times more likely to report sexual debut before age 14, 9.75 times more likely to have >1 sexual partner, and 3.33 times more likely to not have used a condom during last sex. Adolescents living with parents, grandparents, aunts or uncles were less likely to report having unprotected sex compared with those without adult family members in the home (AOR range 0.26-0.51). The high prevalence of risky sex among males and the protective influence of stable family cohesiveness have important implications for HIV prevention efforts.

    Waveform analysis of aftershocks of the Mw7.0 Haiti earthquake of 12 January 2010 reveals amplification of ground motions at sites within the Cul de Sac valley in which Port-au-Prince is situated. Relative to ground motions recorded at a hard-rock reference site, peak acceleration values are amplified by a factor of approximately 1.8 at sites on low-lying Mio-Pliocene deposits in central Port-au-Prince and by a factor of approximately 2.5–3 on a steep foothill ridge in the southern Port-au-Prince metropolitan region. The observed amplitude, predominant periods, variability, and polarization of amplification are consistent with predicted topographic amplification by a steep, narrow ridge. A swath of unusually high damage in this region corresponds with the extent of the ridge where high weak-motion amplifications are observed. We use ASTER (Advanced Spaceborne Thermal Emission and Reflection Radiometer) imagery to map local geomorphology, including characterization of both near-surface and of small-scale topographic structures that correspond to zones of inferred amplification.

    The U.S. Geological Survey produced 1:24,000-scale post-earthquake image base maps incorporating high- and medium-resolution remotely sensed imagery following the 7.0 magnitude earthquake near the capital city of Port au Prince, Haiti, on January 12, 2010. Commercial 2.4-meter multispectral QuickBird imagery was acquired by DigitalGlobe on January 15, 2010, following the initial earthquake. Ten-meter multispectral ALOS AVNIR-2 imagery was collected by the Japanese Space Agency (JAXA) on January 12, 2010. These data were acquired under the Remote Sensing International Charter, a global team of space and satellite agencies that provide timely imagery in support of emergency response efforts worldwide. The images shown on this map were employed to support earthquake response efforts, specifically for use in determining ground deformation, damage assessment, and emergency management decisions. The raw, unprocessed imagery was geo-corrected, mosaicked, and reproduced onto a cartographic 1:24,000-scale base map. These maps are intended to provide a temporally current representation of post-earthquake ground conditions, which may be of use to decision makers and to the general public.

    Continuing education is an integral part of nursing professional development and improving healthcare delivery, but literature on continuing education initiatives in low-resource settings is limited. To describe the creation and integration of a nurse educator (NE) position in two Haitian hospitals and highlight barriers and facilitators experienced by the NEs in their role. Four NEs and three support staff involved in the creation and integration of the NE positions were interviewed. Supplementary data were gathered through participant observation and document review. Data were compiled and summarized. NEs were hired to assess learning needs, evaluate skills, train and mentor nurses, and provide ongoing support to assure application of new knowledge. Barriers included lack of specialized training and limited informational resources to develop education activities, role confusion and heavy workload, poor attendance and disparate education needs of nurses, and insufficient hospital resources and support to implement practice changes. Facilitators included previous management experience, peer support, and a perception of being valued by patients and colleagues and making a difference regarding nursing care and patient outcomes. The NE is a leadership role and a promising, sustainable initiative for developing the nursing profession in Haiti. © 2018 Wiley Periodicals, Inc.

    Full Text Available Abstract Background Towards the end of 2006 open conflict broke out between United Nations forces and armed militia in Port-au-Prince, Haiti. Fighting was most intense in the district of Cité Soleil. Methods A cross-sectional, random-sample survey among the conflict-affected populations living in Cité Soleil and Martissant was carried out over a 4-week period in 2006 using a semi-structured questionnaire to assess exposure to violence and access to health care. Household heads from 945 households (corresponding to 4,763 people in Cité Soleil and 1,800 household (9,539 people in Martissant provided information on household members. The average recall period was 579 days for Cité Soleil and 601 days for Martissant. Results In Cité Soleil 120 deaths (21 children were reported (CMR 0.4 deaths/10,000 people/day; Discussion Extrapolating to the total population of these two districts some 2,000 violent deaths occurred over the recall period. Among the survivors, violence had lasting effects in terms of physical and mental health and loss of property and possessions.

    Full Text Available The goal of this study was to evaluate the microbial die-off in a latrine waste composting system in Port-au-Prince, Haiti. Temperature data and samples were collected from compost aged 0-12+ months. Samples collected from compost bin centers and corners at two depths were assessed for moisture content, E. coli concentration, and Ascaris spp. viability. Center temperatures in compost bins were all above 58 °C, while corner temperatures were 10 - 20 °C lower. Moisture content was 67 ± 10% in all except the oldest compost. A 4-log reduction in E. coli was observed over the first sixteen weeks of composting at both locations and depths, after which E. coli was undetectable (LOD: 142 MPN g(-1 dry weight. In new compost, 10.4% and 8.3% of Ascaris eggs were viable and fully embryonated, respectively. Percent viability dropped to zero in samples older than six weeks. These findings indicate that the Haitian EcoSan composting process was effective in inactivating E. coli and Ascaris spp. in latrine waste within sixteen weeks. This study is one of the first to document efficacy of an ecological sanitation system under field conditions and provides insight into composting methods and monitoring for other international settings.

    The first oral cholera vaccine (OCV) campaign, since its prequalification by the World Health Organization, in response to an ongoing cholera epidemic (reactive vaccination) was successfully conducted in a poor urban slum of approximately 70,000 inhabitants in Port-au-Prince, Haiti, in 2012. Vaccine coverage was 75% of the target population. This report documents the impact of OCV in reducing the number of culture-confirmed cases of cholera admitted to the Groupe Haïtien d'Etude du Sarcome de Kaposi et des Infections Opportunistes (GHESKIO) cholera treatment center from that community in the 37 months postvaccination (April 2012-April 30, 2015). Of 1,788 patients with culture-confirmed cholera, 1,770 (99%) were either from outside the vaccine area (1,400 cases) or from the vaccinated community who had not received OCV (370 cases). Of the 388 people from the catchment area who developed culture-confirmed cholera, 370 occurred among the 17,643 people who had not been vaccinated (2.1%) and the remaining 18 occurred among the 52,357 people (0.034%) who had been vaccinated (P cholera in outbreak settings. © The American Society of Tropical Medicine and Hygiene.

  13. Mapping to Support Fine Scale Epidemiological Cholera Investigations: A Case Study of Spatial Video in Haiti

    2016-02-01

    Full Text Available The cartographic challenge in many developing world environments suffering a high disease burden is a lack of granular environmental covariates suitable for modeling disease outcomes. As a result, epidemiological questions, such as how disease diffuses at intra urban scales are extremely difficult to answer. This paper presents a novel geospatial methodology, spatial video, which can be used to collect and map environmental covariates, while also supporting field epidemiology. An example of epidemic cholera in a coastal town of Haiti is used to illustrate the potential of this new method. Water risks from a 2012 spatial video collection are used to guide a 2014 survey, which concurrently included the collection of water samples, two of which resulted in positive lab results “of interest” (bacteriophage specific for clinical cholera strains to the current cholera situation. By overlaying sample sites on 2012 water risk maps, a further fifteen proposed water sample locations are suggested. These resulted in a third spatial video survey and an additional “of interest” positive water sample. A potential spatial connection between the “of interest” water samples is suggested. The paper concludes with how spatial video can be an integral part of future fine-scale epidemiological investigations for different pathogens.

    Full Text Available The January 2010 earthquake devastated Haiti’s social, economic and health infrastructure, leaving 2 million persons—one-fifth of Haiti’s population—homeless. Internally displaced persons relocated to camps, where human rights remain compromised due to increased poverty, reduced security, and limited access to sanitation and clean water. This article draws on findings from 3 focus groups conducted with internally displaced young women and 3 focus groups with internally displaced young men (aged 18–24 in Leogane, Haiti to explore post-earthquake tent distribution practices. Focus group findings highlighted that community members were not engaged in developing tent distribution strategies. Practices that distributed tents to both children and parents, and linked food and tent distribution, inadvertently contributed to “chaos”, vulnerability to violence and family network breakdown. Moving forward we recommend tent distribution strategies in disaster contexts engage with community members, separate food and tent distribution, and support agency and strategies of self-protection among displaced persons.

  15. Differential Vulnerability to Hurricanes in Cuba, Haiti, and the Dominican Republic: The Contribution of Education

    Full Text Available The possible impacts of the level of formal education on different aspects of disaster management, prevention, alarm, emergency, or postdisaster activities, were studied in a comparative perspective for three countries with a comparable exposure to hurricane hazards but different capacities for preventing harm. The study focused on the role of formal education in reducing vulnerability operating through a long-term learning process and put particular emphasis on the education of women. The comparative statistical analysis of the three countries was complemented through qualitative studies in Cuba and the Dominican Republic collected in 2010-2011. We also analyzed to what degree targeted efforts to reduce vulnerability were interconnected with other policy domains, including education and science, health, national defense, regional development, and cultural factors. We found that better education in the population had clear short-term effects on reducing vulnerability through awareness about crucial information, faster and more efficient responses to alerts, and better postdisaster recuperation. However, there were also important longer term effects of educational efforts to reduce social vulnerability through the empowerment of women, its effect on the quality of institutions and social networks for mutual assistance creating a general culture of safety and preparedness. Not surprisingly, on all three accounts Cuba clearly did the best; whereas Haiti was worst, and the Dominican Republic took an intermediate position.

    The overall state of the art related with neutron capture therapy(NCT) is surveyed. Since the field related with NCT is very wide, it is not intended to survey all related subjects in depth. The primary objective of this report is to help those working for the installation of a NCT facility and a PGNAA(prompt gamma ray neutron activation analysis) system for the boron analysis understand overall NCT at Hanaro. Therefore, while the parts of reactor neutron source and PGNAA are dealt in detail, other parts are limited to the level necessary to understand related fields. For example, the subject of chemical compound which requires intensive knowledge on chemistry, is not dealt as a separated item. However, the requirement of a compound for NCT, currently available compounds, their characteristics, etc. could be understood through this report. Although the subject of cancer treated by NCT is out of the capability of the author, it is dealt focussing its characteristics related with the success of NCT. Each detailed subject is expected to be dealt more detail by specialists in future. This report would be helpful for the researchers working for the NCT to understand related fields.

    Captured by Aliens is a long and twisted voyage from science to the supernatural and back again. I hung out in Roswell, N.M., spent time with the Mars Society, met a guy who was figuring out the best way to build a spaceship to go to Alpha Centauri. I visited the set of the X-Files and talked to Mulder and Scully. One day over breakfast I was told by NASA administrator Dan Goldin, We live in a fog, man! He wants the big answers to the big questions. I spent a night in the base of a huge radio telescope in the boondocks of West Virginia, awaiting the signal from the aliens. I was hypnotized in a hotel room by someone who suspected that I'd been abducted by aliens and that this had triggered my interest in the topic. In the last months of his life, I talked to Carl Sagan, who believed that the galaxy riots with intelligent civilizations. He's my hero, for his steadfast adherence to the scientific method. What I found in all this is that the big question that needs immediate attention is not what's out THERE, but what's going on HERE, on Earth, and why we think the way we do, and how we came to be here in the first place.

    2008-10-15

    This article presented an innovative way to achieve the efficient capture of atmospheric carbon. A team of scientists from the University of Calgary's Institute for Sustainable Energy, Environment and Economy have shown that it is possible to reduce carbon dioxide (CO{sub 2}) using a simple machine that can capture the trace amount of CO{sub 2} present in ambient air at any place on the planet. The thermodynamics of capturing the small concentrations of CO{sub 2} from the air is only slightly more difficult than capturing much larger concentrations of CO{sub 2} from power plants. The research is significant because it offers a way to capture CO{sub 2} emissions from transportation sources such as vehicles and airplanes, which represent more than half of the greenhouse gases emitted on Earth. The energy efficient and cost effective air capture technology could complement other approaches for reducing emissions from the transportation sector, such as biofuels and electric vehicles. Air capture differs from carbon capture and storage (CCS) technology used at coal-fired power plants where CO{sub 2} is captured and pipelined for permanent storage underground. Air capture can capture the CO{sub 2} that is present in ambient air and store it wherever it is cheapest. The team at the University of Calgary showed that CO{sub 2} could be captured directly from the air with less than 100 kWhrs of electricity per tonne of CO{sub 2}. A custom-built tower was able to capture the equivalent of 20 tonnes per year of CO{sub 2} on a single square meter of scrubbing material. The team devised a way to use a chemical process from the pulp and paper industry to cut the energy cost of air capture in half. Although the technology is only in its early stage, it appears that CO{sub 2} could be captured from the air with an energy demand comparable to that needed for CO{sub 2} capture from conventional power plants, but costs will be higher.

    Leaves show a variety of strategies for maximizing CO{sub 2} and light capture. These are more meaningfully explained if they are considered in the context of maximizing capture relative to the utilization of water, nutrients and carbohydrates reserves. There is considerable variation between crops in their efficiency of CO{sub 2} and light capture at the leaf level. Understanding of these mechanisms indicate some ways in which efficiency of resource capture could be level cannot be meaningfully considered without simultaneous understanding of implications at the canopy level. 36 refs., 5 figs., 1 tab.

  2. Establishment of a High Canine Rabies Burden in Haiti through the Implementation of a Novel Surveillance Program [corrected].

    Full Text Available The Republic of Haiti is one of only several countries in the Western Hemisphere in which canine rabies is still endemic. Estimation methods have predicted that 130 human deaths occur per year, yet existing surveillance mechanisms have detected few of these rabies cases. Likewise, canine rabies surveillance capacity has had only limited capacity, detecting only two rabid dogs per year, on average. In 2013, Haiti initiated a community-based animal rabies surveillance program comprised of two components: active community bite investigation and passive animal rabies investigation. From January 2013 -December 2014, 778 rabies suspect animals were reported for investigation. Rabies was laboratory-confirmed in 70 animals (9% and an additional 36 cases were identified based on clinical diagnosis (5%, representing an 18-fold increase in reporting of rabid animals compared to the three years before the program was implemented. Dogs were the most frequent rabid animal (90%. Testing and observation ruled out rabies in 61% of animals investigated. A total of 639 bite victims were reported to the program and an additional 364 bite victims who had not sought medical care were identified during the course of investigations. Only 31% of people with likely rabies exposures had initiated rabies post-exposure prophylaxis prior to the investigation. Rabies is a neglected disease in-part due to a lack of surveillance and understanding about the burden. The surveillance methods employed by this program established a much higher burden of canine rabies in Haiti than previously recognized. The active, community-based bite investigations identified numerous additional rabies exposures and bite victims were referred for appropriate medical care, averting potential human rabies deaths. The use of community-based rabies surveillance programs such as HARSP should be considered in canine rabies endemic countries.

It was expected that disruption of breastfeeding practices would lead to increased infant morbidity, malnutrition and mortality. Haiti's health ministry and the United Nations Children's Fund, in collaboration with local and international nongovernmental organizations, established baby tents in the areas affected by the earthquake. The tents provided a safe place for mothers to breastfeed and for non-breastfed infants to receive ready-to-use infant formula. Such a large and coordinated baby tent response in an emergency context had never been mounted before anywhere in the world. Baby tents were set up in five cities but mainly in Port-au-Prince, where the majority of Haiti's 1555 camps for displaced persons had been established. Between February 2010 and June 2012, 193 baby tents were set up; 180 499 mother-infant pairs and 52 503 pregnant women were registered in the baby tent programme. Of infants younger than 6 months, 70% were reported to be exclusively breastfed and 10% of the "mixed feeders" moved to exclusive breastfeeding while enrolled. In 2010, 13.5% of registered infants could not be breastfed. These infants received ready-to-use infant formula. Thanks to rapid programme scale-up, breastfeeding practices remained undisrupted. However, better evaluation methods and comprehensive guidance on the implementation and monitoring of baby tents are needed for future emergencies, along with a clear strategy for transitioning baby tent activities into facility and community programmes.

    Full Text Available Studies of the immunogenicity of the killed bivalent whole cell oral cholera vaccine, Shanchol, have been performed in historically cholera-endemic areas of Asia. There is a need to assess the immunogenicity of the vaccine in Haiti and other populations without historical exposure to Vibrio cholerae.We measured immune responses after administration of Shanchol, in 25 adults, 51 older children (6-17 years, and 47 younger children (1-5 years in Haiti, where cholera was introduced in 2010. A≥4-fold increase in vibriocidal antibody titer against V. cholerae O1 Ogawa was observed in 91% of adults, 74% of older children, and 73% of younger children after two doses of Shanchol; similar responses were observed against the Inaba serotype. A≥2-fold increase in serum O-antigen specific polysaccharide IgA antibody levels against V. cholerae O1 Ogawa was observed in 59% of adults, 45% of older children, and 61% of younger children; similar responses were observed against the Inaba serotype. We compared immune responses in Haitian individuals with age- and blood group-matched individuals from Bangladesh, a historically cholera-endemic area. The geometric mean vibriocidal titers after the first dose of vaccine were lower in Haitian than in Bangladeshi vaccinees. However, the mean vibriocidal titers did not differ between the two groups after the second dose of the vaccine.A killed bivalent whole cell oral cholera vaccine, Shanchol, is highly immunogenic in Haitian adults and children. A two-dose regimen may be important in Haiti, and other populations lacking previous repeated exposures to V. cholerae.

    Despite growing effects of human activities on climate change throughout the world, and global South in particular, scientists are yet to understand how poor healthcare waste management practices in an emergency influences the climate change. This article presents new findings on climate change risks of healthcare waste disposal during and after the 2010 earthquake and cholera disasters in Haiti. The researchers analysed quantities of healthcare waste incinerated by the United Nations Mission in Haiti for 60 months (2009 to 2013). The aim was to determine the relationship between healthcare waste incinerated weights and the time of occurrence of the two disasters, and associated climate change effects, if any. Pearson product-moment correlation coefficient indicated a weak correlation between the quantities of healthcare waste disposed of and the time of occurrence of the actual emergencies (r (58) = 0.406, p = 0.001). Correspondingly, linear regression analysis indicated a relatively linear data trend (R 2 = 0.16, F (1, 58) = 11.42, P = 0.001) with fluctuating scenarios that depicted a sharp rise in 2012, and time series model showed monthly and yearly variations within 60 months. Given that the peak healthcare waste incineration occurred 2 years after the 2010 disasters, points at the need to minimise wastage on pharmaceuticals by improving logistics management. The Government of Haiti had no data on healthcare waste disposal and practised smoky open burning, thus a need for capacity building on green healthcare waste management technologies for effective climate change mitigation.

    In 2010, a magnitude 7.0 earthquake struck Haiti, severely damaging the drinking and wastewater infrastructure and leaving millions homeless. Compounding this problem, the introduction of Vibrio cholerae resulted in a massive cholera outbreak that infected over 700,000 people and threatened the safety of Haiti's drinking water. To mitigate this public health crisis, non-government organizations installed thousands of wells to provide communities with safe drinking water. However, despite increased access, Haiti currently lacks the monitoring capacity to assure the microbial safety of any of its water resources. For these reasons, this study was designed to assess the feasibility of using a simple, low-cost method to detect indicators of fecal contamination of drinking water that could be implemented at the community level. Water samples from 358 sources of drinking water in the Léogâne flood basin were screened with a commercially available hydrogen sulfide test and a standard membrane method for the enumeration of thermotolerant coliforms. When compared with the gold standard method, the hydrogen sulfide test had a sensitivity of 65 % and a specificity of 93 %. While the sensitivity of the assay increased at higher fecal coliform concentrations, it never exceeded 88 %, even with fecal coliform concentrations greater than 100 colony-forming units per 100 ml. While its simplicity makes the hydrogen sulfide test attractive for assessing water quality in low-resource settings, the low sensitivity raises concerns about its use as the sole indicator of the presence or absence of fecal coliforms in individual or community water sources.

    Absence of outcome data is a barrier to quality improvement in resource poor settings. To address this challenge, we set out to determine whether follow up for surgical site infections (SSIs) using community health workers (CHWs) and smartphones is feasible in rural Haiti. In this pilot study, all patients from a specific mountain region who received an operation between March 10, and July 1, 2014, at Hôpital Albert Schweitzer in rural Haiti were eligible for inclusion. Patients or guardians of minors were approached for consent. We designed a smartphone application to enable CHWs to screen for SSIs during home visits by administering a questionnaire, obtaining GPS data, and submitting a photograph of an incision. We selected and trained CHWs to use the smartphone application and compensated them based on performance. CHWs completed home visits for 30 days after an operation for all participants. Surgeons examined all participants within 24 h after the second CHW home visit. Primary outcomes included the number of participants completing 30-day follow-up and home visits made on time. Secondary outcomes included the quality of the photographs and the agreement between surgeons and CHWs on the diagnosis of SSI. The Partners Healthcare institutional review board and the Ethics Committee at Hôpital Albert Schweitzer approved the study protocol. Five CHWs completed 30-day follow up for 37 of 39 participants (94·9%) and completed 107 of 117 home visits on time (91·5%). High quality photographs were submitted for 101 of 117 visits (86·3%). Surgeons and CHWs agreed on the diagnosis of SSI in 28 of 33 cases (84·8%). Outpatient follow up for SSIs with CHWs and smartphones is feasible in rural Haiti. Further validation of the programme needs to be done before widespread adoption or advocating for task shifting post-operative follow up to CHWs.

    Limited information is available regarding the causes of under-five mortality in nearly all of the countries in which mortality is the highest. The purpose of this study was to use a standard computerized protocol for defining the leading causes of death among children in a high-mortality rural population of Haiti and to highlight the need for similar studies else-where in Haiti and throughout the high-mortality areas of Latin America and the Caribbean. In 2001 a standardized, closed-ended verbal autopsy questionnaire endorsed by the World Health Organization was administered to a representative, population-based sample of the mothers or other caregivers of 97 children who had died before reaching 5 years of age between 1995 and 1999 in the service area of the Albert Schweitzer Hospital, which is located in the rural Artibonite Valley of Haiti. With the data from the questionnaires we used a computerized algorithm to generate diagnoses of the cause of death; the algorithm made it possible to have more than one cause of death. Acute lower respiratory infection (ALRI) was the leading diagnosis, present in 45% of all under-five deaths, followed by enteric diseases, present in 21% of deaths. Neonatal tetanus, preterm birth, and other early neonatal causes unassociated with ALRI or diarrhea were present in 41% of the neonatal deaths. Among children 1-59 months of age, ALRI was present in 51% of the deaths, and enteric diseases in 30%. Deaths were concentrated during the first few months of life, with 35% occurring during the first month. Among the neonatal deaths, 27% occurred on the first day of life, and 80% occurred during the first 10 days of life. In the Albert Schweitzer Hospital program area--and presumably in other areas of Haiti as well--priority needs to be given to the prevention of and the early, effective treatment of ALRI, diarrhea, and early neonatal conditions. This study points to the need for more, similar standardized assessments to guide local

    Full Text Available Haiti has the highest number of people living with HIV infection in the Caribbean/Latin America region. Medical male circumcision (MMC has been recommended to help prevent the spread of HIV. We sought to assess knowledge, attitudes, practices and beliefs about MMC among a sample of health care providers in Haiti.A convenience sample of 153 health care providers at the GHESKIO Centers in Haiti responded to an exploratory survey that collected information on several topics relevant to health providers about MMC. Descriptive statistics were calculated for the responses and multivariable logistic regression was conducted to determine opinions of health care providers about the best age to perform MMC on males. Bayesian network analysis and sensitivity analysis were done to identify the minimum level of change required to increase the acceptability of performing MMC at age less than 1 year.The sample consisted of medical doctors (31.0%, nurses (49.0%, and other health care professionals (20.0%. Approximately 76% showed willingness to offer MMC services if they received training. Seventy-six percent believed that their male patients would accept circumcision, and 59% believed infancy was the best age for MMC. More than 90% of participants said that MMC would reduce STIs. Physicians and nurses who were willing to offer MMC if provided with adequate training were 2.5 (1.15-5.71 times as likely to choose the best age to perform MMC as less than one year. Finally, if the joint probability of choosing "the best age to perform MMC" as one year or older and having the mistaken belief that "MMC prevents HIV entirely" is reduced by 63% then the probability of finding that performing MMC at less than one year acceptable to health care providers is increased by 35%.Participants demonstrated high levels of knowledge and positive attitudes towards MMC. Although this study suggests that circumcision is acceptable among certain health providers in Haiti, studies

    Data on air quality are remarkably limited in the poorest of the world's countries. This is especially true for post-conflict and disaster zones, where international relief efforts focus largely on more salient public health challenges such as water and sanitation, infectious diseases, and housing. Using post-earthquake Haiti as the example case, this commentary explores air quality challenges in the developing world, highlighting concerns related to infrastructure damage from post-conflict and disaster settings. We contend that there is a growing and presently unmet need for further research and attention from the global health community to address these issues. Copyright © 2014 Elsevier B.V.

    Synthetic aperture radar (SAR) multi-temporal interferometry (MTI) is one of the most promising satellite-based remote sensing techniques for fostering new opportunities in landslide hazard detection and assessment. MTI is attractive because it can provide very precise quantitative information on slow slope displacements of the ground surface over huge areas with limited vegetation cover. Although MTI is a mature technique, we are only beginning to realize the benefits of the high-resolution imagery that is currently acquired by the new generation radar satellites (e.g., COSMO-SkyMed, TerraSAR-X). In this work we demonstrate the potential of high resolution X-band MTI for wide-area detection of slope instability hazards even in tropical environments that are typically very harsh (eg. coherence loss) for differential interferometry applications. This is done by presenting an example from the island of Haiti, a tropical region characterized by dense and rapidly growing vegetation, as well as by significant climatic variability (two rainy seasons) with intense precipitation events. Despite the unfavorable setting, MTI processing of nearly 100 COSMO-SkyMed (CSK) mages (2011-2013) resulted in the identification of numerous radar targets even in some rural (inhabited) areas thanks to the high resolution (3 m) of CSK radar imagery, the adoption of a patch wise processing SPINUA approach and the presence of many man-made structures dispersed in heavily vegetated terrain. In particular, the density of the targets resulted suitable for the detection of some deep-seated and shallower landslides, as well as localized, very slow slope deformations. The interpretation and widespread exploitation of high resolution MTI data was facilitated by Google EarthTM tools with the associated high resolution optical imagery. Furthermore, our reconnaissance in situ checks confirmed that MTI results provided useful information on landslides and marginally stable slopes that can represent a

  14. Iodine neutron capture therapy

    Ahmed, Kazi Fariduddin

    A new technique, Iodine Neutron Capture Therapy (INCT) is proposed to treat hyperthyroidism in people. Present thyroid therapies, surgical removal and 131I treatment, result in hypothyroidism and, for 131I, involve protracted treatment times and excessive whole-body radiation doses. The new technique involves using a low energy neutron beam to convert a fraction of the natural iodine stored in the thyroid to radioactive 128I, which has a 24-minute half-life and decays by emitting 2.12-MeV beta particles. The beta particles are absorbed in and damage some thyroid tissue cells and consequently reduce the production and release of thyroid hormones to the blood stream. Treatment times and whole-body radiation doses are thus reduced substantially. This dissertation addresses the first of the several steps needed to obtain medical profession acceptance and regulatory approval to implement this therapy. As with other such programs, initial feasibility is established by performing experiments on suitable small mammals. Laboratory rats were used and their thyroids were exposed to the beta particles coming from small encapsulated amounts of 128I. Masses of 89.0 mg reagent-grade elemental iodine crystals have been activated in the ISU AGN-201 reactor to provide 0.033 mBq of 128I. This activity delivers 0.2 Gy to the thyroid gland of 300-g male rats having fresh thyroid tissue masses of ˜20 mg. Larger iodine masses are used to provide greater doses. The activated iodine is encapsulated to form a thin (0.16 cm 2/mg) patch that is then applied directly to the surgically exposed thyroid of an anesthetized rat. Direct neutron irradiation of a rat's thyroid was not possible due to its small size. Direct in-vivo exposure of the thyroid of the rat to the emitted radiation from 128I is allowed to continue for 2.5 hours (6 half-lives). Pre- and post-exposure blood samples are taken to quantify thyroid hormone levels. The serum T4 concentration is measured by radioimmunoassay at

    The Mw 7.0 January 12, 2010 Haiti earthquake ended 240 years of relative quiescence following earthquakes that destroyed Port-au-Prince in 1751 and 1770. We place the 2010 rupture in the context of past earthquakes and future hazards by using remote analysis of airborne LiDAR to observe the topographic expression of active faulting and develop a new conceptual model for the earthquake behavior of the eastern Enriquillo fault zone (EFZ). In this model, the 2010 event occupies a long-lived segment boundary at a stepover within the EFZ separating fault segments that likely ruptured in 1751 and 1770, explaining both past clustering and the lack of 2010 surface rupture. Immediately following the 2010 earthquake, an airborne LiDAR point cloud containing over 2.7 billion point measurements of surface features was collected by the Rochester Inst. of Technology. To analyze these data, we capitalize on the human capacity to visually identify meaningful patterns embedded in noisy data by conducting interactive visual analysis of the entire 66.8 GB Haiti terrain data in a 4-sided, 800 ft3 immersive virtual-reality environment at the UC Davis KeckCAVES using the software tools LiDAR Viewer (to analyze point cloud data) and Crusta (for 3D surficial geologic mapping on DEM data). We discovered and measured landforms displaced by past surface-rupturing earthquakes and remotely characterized the regional fault geometry. Our analysis of the ~50 km long reach of EFZ spanning the 2010 epicenter indicates that geomorphic evidence of active faulting is clearer east of the epicenter than to the west. West of the epicenter, and in the region of the 2010 rupture, the fault is poorly defined along an embayed, low-relief range front, with little evidence of recent surface rupture. In contrast, landform offsets of 6 to 50 m along the reach of the EFZ east of the epicenter and closest to Port-au-Prince attest to repeated recent surface-rupturing earthquakes here. Specifically, we found and

The study characterized ART attrition levels and explored the patient demographic, clinical, temporal, and service utilization factors associated with ART attrition, using time-to-event analysis methods. Among the 2 023 patients in the study, ART attrition on average was 17.0 per 100 person-years (95% confidence interval (CI): 15.8-18.3). In adjusted analyses, risk of ART attrition was up to 89% higher for patients living in distant communes compared to patients living in the same commune as the hospital (hazard ratio: 1.89, 95%CI: 1.54-2.33; P Hospital site, earlier year of ART start, spending less time enrolled in HIV care prior to ART initiation, receiving a non-standard ART regimen, lacking counseling prior to ART initiation, and having a higher body mass index were also associated with attrition risk. The findings suggest quality improvement interventions at the two hospitals, including: enhanced retention support and transportation subsidies for patients accessing care from remote areas; counseling for all patients prior to ART initiation; timely outreach to patients who miss ART pick-ups; "bridging services" for patients transferring care to alternative facilities; routine screening for anticipated interruptions in future ART pick-ups; and medical case review for patients placed on non-standard ART regimens. The findings are also relevant for policymaking on decentralization of ART services in Haiti.

    In Haiti, as in several developing countries, the phenomenon of street children has become a major public health issue. These children are often victims of traumas and adverse life events. This article aimed to investigate traumas experienced by street children and their coping and resilience strategies used to deal with adversities in a logic of survival, relying on a mixed method approach. A group of 176 street children, aged 7-18 (n = 21 girls), recruited in Port-au-Prince, completed measures assessing PTSD, social support and resilience. Semi-structured interviews were conducted to document traumatic experiences, factors related to resilience and coping strategies. After performing statistical analyses to evaluate prevalence and predictors associated with PTSD, and level of social support satisfaction and resilience, qualitative analysis using a grounded theory approach was conducted. Results showed that street children experienced multiple traumas such as neglect, maltreatment, psychological, physical and sexual abuse. However, they also showed self-efficacy to face their traumatic experiences and few of them (less than 15%) obtained scores reaching clinical rates of PTSD, while a large majority presented a level of resilience between moderate to very high. A socio-ecological model of multiple traumas and a model of coping, survival and resilience strategies are conceptualized. Data provide a better understanding of the traumas experienced by street children, their coping and resilience strategies. Results underscore ways to develop practices to offer psychological support, social and vocational integration based on the real needs of these children, in a perspective of social justice.

    As a major cholera epidemic progresses in Haiti, and the figures of the infection, up to December 2011, climb to 522,000 cases and 7,000 deaths, the development of general models to track and predict the evolution of the outbreak, so as to guide the allocation of medical supplies and staff, is gaining notable urgency. We propose here a spatially explicit epidemic model that accounts for the dynamics of susceptible and infected individuals as well as the redistribution of Vibrio cholera, the causative agent of the disease, among different human communities. In particular, we model two spreading pathways: the advection of pathogens through hydrologic connections and the dissemination due to human mobility described by means of a gravity-like model. To this end the country has been divided into hydrologic units based on drainage directions derived from a digital terrain model. Moreover the population of each unit has been estimated from census data downscaled to 1 km x 1 km resolution via remotely sensed geomorphological information (LandScan project). The model directly accounts for the role of rainfall patterns in driving the seasonality of cholera outbreaks. The two main outbreaks in fact occurred during the rainy seasons (October and May) when extensive floodings severely worsened the sanitation conditions and, in turn, raised the risk of infection. The model capability to reproduce the spatiotemporal features of the epidemic up to date grants robustness to the foreseen future development. To this end, we generate realistic scenario of future precipitation in order to forecast possible epidemic paths up to the end of the 2013. In this context, the duration of acquired immunity, a hotly debated topic in the scientific community, emerges as a controlling factor for progression of the epidemic in the near future. The framework presented here can straightforwardly be used to evaluate the effectiveness of alternative intervention strategies like mass vaccinations

The purpose of the survey was to understand how the humanitarian aid system adopts or incorporates human rights into its post-natural disaster work and metrics. Data collected from Haiti suggest that humanitarians have embraced a rights-based approach but that they do not agree about how this is defined or about what standards and indicators can be considered rights-based. This disagreement may reveal that humanitarians are aware of a mismatch between the rights-based approach to post-disaster humanitarian work and the legal framework of human rights. Using participation and accountability as examples, this article identifies and examines this mismatch and suggests that the humanitarian aid system should more fully embrace engagement with the human rights framework. To do so, the article concludes, humanitarian actors and the human rights community should have an open dialogue about the development of metrics that accurately reflect and monitor adherence to the legal framework of human rights. This would allow the humanitarian aid system to ensure its interventions enhance the capacity of the disaster-affected state to fulfill its human rights obligations, and would allow humanitarian and human rights actors alike to measure the impact of such interventions on the realization of human rights in post-natural disaster settings.

  3. The Jollywood Manifesto: Trans-local Film Cultures in Haiti's Emerging Cinemas

    2015-10-01

    Full Text Available Taking into account Haiti’s peripheral and/or temporary position within World Cinema’s politics, this paper focuses on a recent phenomenon of cinematographic productions of Haiti’s emerging filmmaker’s generation: Jollywood. The Ciné Institute is the only film school in the French-speaking part of the West Indies that currently provides training to a young generation of filmmakers and videographers. Its Jollywood Manifesto is based on the political, cultural and societal as well as media-related vision of a self-sustaining film market in Haiti. Based on lowest-budget productions made possible by the huge rise of digital film, this recent phenomenon not only asks for new modes of production, circulating distribution and reception. It also stands for a reconsideration of film and media theory for “internationalized” World Cinemas on a discursive level. This level will be approached by interlacing a twofold concept: On the one hand, theories on (Post- Third Cinemas that have been known since their inception in the late 1960s in Latin America and that have subsequently been adapted in the Asian and African Cinemas. On the other hand, today’s assumptions of considering cinema in its political message on a transglobal space are called into question. The global film market, mostly dominated by the triad of Bollywood, Nollywood and Hollywood, also questions the margins of hegemonic centerlines of power relations. Haiti’s cinematic productions are located at the interstices of local and national(ist  imaginaries in line with a (postcolonial independent film industry. This ambiguity stands for the resulting translocal and transcultural attributions of Haiti’s emerging film cultures and the ambiguous formations of the notions of being and belonging. The analysis of the Jollywood phenomenon on transnational/-local/-cultural levels aims at a methodological detangling of geopolitical spaces and temporalities in the media.

    Computational models of cholera transmission can provide objective insights into the course of an ongoing epidemic and aid decision making on allocation of health care resources. However, models are typically designed, calibrated and interpreted post-hoc. Here, we report the efforts of a team from academia, field research and humanitarian organizations to model in near real-time the Haitian cholera outbreak after Hurricane Matthew in October 2016, to assess risk and to quantitatively estimate the efficacy of a then ongoing vaccination campaign. A rainfall-driven, spatially-explicit meta-community model of cholera transmission was coupled to a data assimilation scheme for computing short-term projections of the epidemic in near real-time. The model was used to forecast cholera incidence for the months after the passage of the hurricane (October-December 2016) and to predict the impact of a planned oral cholera vaccination campaign. Our first projection, from October 29 to December 31, predicted the highest incidence in the departments of Grande Anse and Sud, accounting for about 45% of the total cases in Haiti. The projection included a second peak in cholera incidence in early December largely driven by heavy rainfall forecasts, confirming the urgency for rapid intervention. A second projection (from November 12 to December 31) used updated rainfall forecasts to estimate that 835 cases would be averted by vaccinations in Grande Anse (90% Prediction Interval [PI] 476-1284) and 995 in Sud (90% PI 508-2043). The experience gained by this modeling effort shows that state-of-the-art computational modeling and data-assimilation methods can produce informative near real-time projections of cholera incidence. Collaboration among modelers and field epidemiologists is indispensable to gain fast access to field data and to translate model results into operational recommendations for emergency management during an outbreak. Future efforts should thus draw together multi

    Full Text Available John C Jackson, Anthony L Farone, Mary B Farone Biology Department, Middle Tennessee State University, Murfreesboro, Tennessee, USA Purpose: Diarrheal disease is one of the leading causes of morbidity in developing countries. To further understand the epidemiology of diarrheal disease among a rural population surrounding Robillard, Haiti, fecal swabs from patients with diarrhea were screened for the presence of enteropathogenic bacteria. Patients and methods: Fecal swabs were collected from 34 patients with signs and symptoms of diarrhea and stored in BBLTM Cary-Blair transport medium (Becton, Dickinson and Company, Sparks, MD until transit to the USA. Swab material was inoculated on to different enrichment and selective agars for incubation. Fermenting and nonfermenting bacteria that grew on the enteric selection media were identified by the BBLTM CrystalTM Enteric/Nonferementing Identification system (Becton, Dickinson and Company. Organisms identified as Escherichia coli were further screened for the presence of virulence factors by polymerase chain reaction (PCR. Results: Of 34 patients, no Campylobacter, Shigella, Salmonella, or Vibrio spp. were isolated from swabs transported to the USA for culture. Of 73 E. coli isolates cultured from the swabs, one enteropathogenic strain of E. coli was identified by multiplex PCR. Escherichia fergusonii and Cronobacter sakazakii, both potential gastrointestinal pathogens, were also isolated from patient stools. Conclusion: This study was undertaken to determine if bacterial enteropathogens could be detected in the stools of patients suffering from diarrhea or dysentery and, in the absence of sufficient facilities, rectal swabs could be transported to the USA for culture. Although several genera of overt enteropathogens were not detected, one enteropathogenic E. coli and other pathogenic enterobacteriaceae were successfully cultured and identified.

    In the aftermath of the 2010 earthquake in Haiti, St. Luke Hospital was built to help manage the mass casualties and subsequent cholera epidemic. A major problem faced by the hospital system was the lack of an available and sustainable supply of medications. Long-term viability of the hospital system depended largely on developing an uninterrupted medication supply chain. We hypothesized that the implementation of a new Pharmacy Computerized Inventory Program (PCIP) would optimize medication availability and decrease medication shortages. We conducted the research by examining how medications were being utilized and distributed before and after the implementation of PCIP. We measured the number of documented medication transactions in both Phase 1 and Phase 2 as well as user logins to determine if a computerized inventory system would be beneficial in providing a sustainable, long-term solution to their medication management needs. The PCIP incorporated drug ordering, filling the drug requests, distribution, and dispensing of the medications in multiple settings; inventory of currently shelved medications; and graphic reporting of 'real-time' medication usage. During the PCIP initiation and establishment periods, the number of medication transactions increased from 219.6 to 359.5 (p=0.055), respectively, and the mean logins per day increased from 24.3 to 31.5, psupply as well as track usage for future medication needs. The pharmacy and nursing staff found the PCIP to be efficient and a significant improvement in their medication utilization. An efficient, customizable, and cost-sensitive PCIP can improve drug inventory management in a simplified and sustainable manner within a resource-constrained hospital.

    Full Text Available Abstract Background Human monoclonal antibodies (MAbs are needed for colon cancer radioimmunotherapy (RIT to allow for repeated injections. Carcinoembryonic antigen (CEA being the reference antigen for immunotargeting of these tumors, we developed human anti-CEA MAbs. Methods XenoMouse®-G2 animals were immunized with CEA. Among all the antibodies produced, two of them, VG-IgG2κ and VG-IgM, were selected for characterization in vitro in comparison with the human-mouse chimeric anti-CEA MAb X4 using flow cytometry, surface plasmon resonance, and binding to radiolabeled soluble CEA and in vivo in human colon carcinoma LS174T bearing nude mice. Results Flow cytometry analysis demonstrated binding of MAbs on CEA-expressing cells without any binding on NCA-expressing human granulocytes. In a competitive binding assay using five reference MAbs, directed against the five Gold CEA epitopes, VG-IgG2κ and VG-IgM were shown to be directed against the Gold 4 epitope. The affinities of purified VG-IgG2κ and VG-IgM were determined to be 0.19 ± 0.06 × 108 M-1 and 1.30 ± 0.06 × 108 M-1, respectively, as compared with 0.61 ± 0.05 × 108 M-1 for the reference MAb X4. In a soluble phase assay, the binding capacities of VG-IgG2κ and VG-IgM to soluble CEA were clearly lower than that of the control chimeric MAb X4. A human MAb concentration of about 10-7 M was needed to precipitate approximatively 1 ng 125I-rhCEA as compared with 10-9 M for MAb X4, suggesting a preferential binding of the human MAbs to solid phase CEA. In vivo, 24 h post-injection, 125I-VG-IgG2κ demonstrated a high tumor uptake (25.4 ± 7.3%ID/g, close to that of 131I-X4 (21.7 ± 7.2%ID/g. At 72 h post-injection, 125I-VG-IgG2κ was still concentrated in the tumor (28.4 ± 11.0%ID/g whereas the tumor concentration of 131I-X4 was significantly reduced (12.5 ± 4.8%ID/g. At no time after injection was there any accumulation of the radiolabeled MAbs in normal tissues. A pertinent analysis of

    The 2010 earthquake resulted in the breakdown of Haiti's social, economic and health infrastructure. Over one-quarter of a million people remain internally displaced (ID). ID women experience heightened vulnerability to intimate partner violence (IPV) due to increased poverty and reduced community networks. Scant research has examined experiences of IPV among ID women in post-earthquake Haiti. We conducted a qualitative study to explore the impact of participating in Famn an Aksyon Pou Santé Yo (FASY), a small-group HIV prevention intervention, on ID women's agency in Leogane, Haiti. We conducted four focus groups with ID women, FASY participants (n = 40) and in-depth individual interviews with peer health workers (n = 7). Our study was guided by critical ethnography and paid particular attention to power relations. Findings highlighted multiple forms of IPV (e.g., physical, sexual). Participants discussed processes of intrapersonal (confidence), interpersonal (communication), relational (support) and collective (women's rights) agency. Yet structural factors, including patriarchal gender norms and poverty, silenced IPV discussions and constrained women's agency. Findings suggest that agency among ID women is a multi-level, non-linear and incremental process. To effectively address IPV among ID women in Haiti, interventions should address structural contexts of gender inequity and poverty and concurrently facilitate multi-level processes of agency.

    In order, to investigate the function of electron capture in the phenomenon of pre-supernovae gravitacional collapse, an hydrodynamic caculation was carried out, coupling capture, decay and nuclear reaction equation system. A star simplified model (homogeneous model) was adopted using fermi ideal gas approximation for tthe sea of free electrons and neutrons. The non simplified treatment from quasi-static evolution to collapse is presented. The capture and beta decay rates, as wellas neutron delayed emission, were calculated by beta decay crude theory, while the other reaction rates were determined by usual theories. The preliminary results are presented. (M.C.K.) [pt

    In the Kazama-Yang approximation, the lowest monopole-proton bound states have binding energies of 938 MeV, 263 keV, 105 eV, and 0.04 eV. The cross section for radiative capture to these states is for velocities β = 10 -5 - 10 -3 found to be of the order of 10 -28 - 10 -26 cm 2 . For the state that has a binding energy of 263 keV, the capture length in water is 171 x (β/10 -4 )sup(0.48) m. Observation of photons from the capture process would indicate the presence of monopoles. (orig.)

    Full Text Available Natural disasters have inherently social dimensions because they exacerbate preexisting inequalities and disrupt social norms and institutions. Despite a growing interest in the sociological aspects of disasters, few studies have quantitatively explored how disasters alter intrahousehold family dynamics. In this article, we develop and test a conceptual framework that explicates how natural disasters affect an important component of family life: intimate partner violence (IPV. We combine two waves of geocoded Demographic and Health Surveys data, collected before and after the 2010 earthquake in Haiti, with spatial data on variation in the earthquake’s destruction. Our findings indicate that exposure to earthquake devastation increased the probability of both physical and sexual IPV one to two years following the disaster. These increases were accompanied by substantial changes in family functioning, the household economy, and women’s access to their social networks. Select household-level experiences during and after the earthquake, such as displacement, were also positively associated with IPV. These findings provide new insights into the multidimensional effects of disasters on family life and have important theoretical and policy implications that extend beyond the particular case of Haiti.

    Objectives Cervical cancer is the leading cause of cancer deaths among women in Haiti. Given this high disease burden, we sought to better understand women’s knowledge of its causes and the socio-demographic and health correlates of cervical cancer screening. Methods Participants were 410 adult women presenting at clinics in Léogâne and Port-au-Prince, Haiti. We used bivariate and multivariate logic regression to identify correlates of Pap smear receipt. Results Only 29% of respondents had heard of human papillomavirus (HPV), while 98% were aware of cervical cancer. Of those aware of cervical cancer, 12% believed sexually transmitted infections (STIs) cause it, and only 4% identified HPV infection as the cause. Women with a previous STI were more likely to have had Pap smear (34% vs. 71%, OR=3.45; 95% CI: 1.57–7.59). Screening was also more likely among women who were older than age 39, better educated and employed (all p<.05). Almost all women (97%) were willing to undergo cervical cancer screening. Conclusions This sample of Haitian women had limited awareness of HPV and cervical cancer causes; but when provided with health information, they saw the benefits of cancer screening. Future initiatives should provide health education messages, with efforts targeting young and at-risk women. PMID:27906806

    HIV testing serves as the gateway to HIV prevention and treatment. However, research examining men's HIV testing behaviors in the Caribbean remains limited. The Andersen Behavioral Model of Health Services Utilization was used to examine factors associated with HIV testing among 7,354 men who participated in the 2012 Demographic and Health Survey conducted in Haiti. Few men (35%) reported having ever been tested for HIV. Logistic regression analyses revealed that HIV testing increased with education and wealth. Marital status was associated with HIV testing, with married men more likely to have been tested (adjusted odds ratio: 2.57, 95% CI [2.07, 3.19]) than unmarried men. Positive attitudes toward people living with HIV, indicated by willing to care for a relative who has HIV/AIDS, was also correlated with higher odds of having been tested (adjusted odds ratio: 1.28, 95% CI [1.08, 1.51]). Men who reported condom use during last sex were more likely to have been tested (odds ratio: 1.58, 95% CI [1.33, 1.88). The findings indicate that HIV testing rates remain low among men in Haiti and more efforts are needed to increase HIV testing among men who are not married, have low level of education, and engage in unprotected sex.

    On 12 January 2010, a magnitude 7.0 earthquake devastated Haiti killing over 230,000 unsuspecting victims, injuring tens of thousands more and displacing over 1.1 million people. The physical damage was so severe that over 50 percent of buildings in and near the affected areas were completely destroyed or damaged. After struggling for decades with adversity, and besieged by a myriad of social, economic and political challenges, Haiti, its government, and its people were by most accounts already in a state of crisis. The earthquake's devastation and its aftermath shocked the world and prompted a global response. Over 800 institutions and organizations representing the whole of society - governments and their militaries, international organizations, nongovernmental organizations, public institutions, academia, corporations, and private citizens - mobilized to provide aid and relief. However, coordinating and managing their activities seemed a daunting, if not impossible, task. How could a global response achieve "unity of effort" when "unity of command" was not feasible? To provide a solution, US Southern Command (USSOUTHCOM) looked beyond traditional Command and Control systems for collaboration with non-traditional partners and implemented the All Partners Access Network (APAN) in order to "Connect and Collaborate."

    To prevent undernutrition in an urban slum in Haiti, a lipid-based nutrient supplement (LNS) was introduced through a randomised control trial. Food supplementation for young child nutrition has a long history in Haiti, but there is little empirical information regarding the effects of supplementation on young child feeding practices. One of the concerns raised by supplementation is that it may disrupt other positive feeding practices such as breastfeeding and use of other complementary foods, with negative consequences for child nutrition. We conducted 29 in-depth interviews with mother-baby pairs from the three comparison groups: control, 3-month LNS supplementation and 6-month LNS supplementation. Findings from those in the LNS groups indicated high acceptance and satisfaction with LNS and perceptions that it positively affects child health and development. LNS was integrated into and enhanced ongoing complementary feeding practices. The effects of LNS use on duration and perceived quantity of breastfeeding were variable, but generally, breastfeeding was maintained during and after the intervention. Interviews generated insights into beliefs regarding infant and young child feeding practices such as introduction and use of complementary foods, and breastfeeding duration, exclusivity and cessation. Implications for the use of LNS in public health nutrition programmes are discussed. © 2014 John Wiley & Sons Ltd.

    Describing genetic diversity of the Plasmodium falciparum parasite provides important information about the local epidemiology of malaria. In this study, we examined the genetic diversity of P. falciparum isolates from the Artibonite Valley in Haiti using the allelic families of merozoite surface protein 1 and 2 genes (msp-1 and msp-2). The majority of study subjects infected with P. falciparum had a single parasite genotype (56% for msp-1 and 69% for msp-2: n=79); 9 distinct msp-1 genotypes were identified by size differences on agarose gels. K1 was the most polymorphic allelic family with 5 genotypes (amplicons from 100 to 300 base pairs [bp]); RO33 was the least polymorphic, with a single genotype (120-bp). Although both msp-2 alleles (3D7/IC1, FC27) had similar number of genotypes (n=4), 3D7/IC1 was more frequent (85% vs. 26%). All samples were screened for the presence of the K76T mutation on the P. falciparum chloroquine resistance transporter (pfcrt) gene with 10 of 79 samples positive. Of the 2 (out of 10) samples from individuals follow-up for 21 days, P. falciparum parasites were present through day 7 after treatment with chloroquine. No parasites were found on day 21. Our results suggest that the level of genetic diversity is low in this area of Haiti, which is consistent with an area of low transmission. Copyright © 2011 Elsevier B.V. All rights reserved.

    Full Text Available Haity has a notable problem of food security, 48% of people have not sufficient food availability, food prices has doubled from 1980 and 1990 and further increased 5 times between 1991 and 2000. Water availability and quality is another problems to be added to food insufficiency. Food deficiency is mitigated by natural food resources in rural areas where many different species are cultivated together but it can be extreme in the towns. Agricultural systems are not efficient and, at the same time, enhance soil and genetic erosion. A development project has been implemented to increase food security over the long term in the geographical area of Carrefour rural area, this comprises a research aimed to increase national food production introducing complex agro-forestry systems. The project has investigated problems and solutions, actions have been started to increase food production, including agronomic training of local farmers, organization of small farmers including legal protection on land tenure, introduction of low input modern agroforestry systems that can diversify food production through the year and reduce soil and genetic erosion. After these results, an intervention project has been approved and funded by EU, then delayed due to the recent civil war, finally it is giving positive results now. The same approach used for this project can be spread in the rest of the Republic of Haiti and, hopefully, to other world regions that have similar problems.

    No previous published research has examined the applicability of varying methods for identifying young people who are at high risk of experiencing unintended pregnancy and acquiring HIV infection. This study compares three surveys of young people aged 15-24 in Port-au-Prince, Haiti, in terms of their sociodemographic characteristics and sexual behaviors and the surveys'usefulness for identifying young people at high risk and for program planning. The surveys consist of responses from: a representative sample of young people in the 2005-06 Haiti Demographic and Health Survey (HDHS), a 2004 facility-based study, and a 2006-07 venue-based study that used the Priorities for Local AIDS Control Efforts (PLACE) method. The facility-based and PLACE studies included larger proportions of single, sexually experienced young people and people who knew someone with HIV/ AIDS than did the HDHS. More respondents in the PLACE sample had multiple sex partners in the past year and received money or gifts in return for sex, compared with respondents in the facility study. At first and last sex, more PLACE respondents used contraceptives, including condoms. Experience of pregnancy was most commonly reported in the data from the facility-based sample; however, more ever-pregnant PLACE respondents than others reported ever having terminated a pregnancy. Program managers seeking to implement prevention activities should consider using facility- or venue-based methods to identify and understand the behaviors of young people at high risk.

It exist in almost all living organisms and catalyses different important processes like CO2 transport, respiration and the acid-base balances. A new technology in the field...... of carbon capture is the application of enzymes for acceleration of typically slow ternary amines or inorganic carbonates. There is a hidden potential to revive currently infeasible amines which have an interesting low energy consumption for regeneration but too slow kinetics for viable CO2 capture.

  8. Negative meson capture in hydrogen

    The processes of deexcitation and capture of negative mesons and hadrons in atomic hydrogen are investigated. Only slow collisions in which the projectile-atom relative velocity is less than one atomic unit are considered, and the motion of the incident particle is treated classically. For each classical trajectory the probability of ionizing the hydrogen atom is determined, together with the energy spectrum of the emitted electron. Ionization probabilities are calculated using the time-dependent formulation of the perturbed stationary state method. Exact two-center electronic wave functions are used for both bound and continuum states. The total ionization cross section and electron energy spectrum have been calculated for negative muons, kaons and antiprotons at incident relative velocities between 0.04 and 1.0 atomic units. The electron energy spectrum has a sharp peak for electron kinetic energies on the order of 10 -3 Rydbergs. The ionization process thus favors the emission of very slow electrons. The cross section for ionization with capture of the incident particle was calculated for relative kinetic energies greater than 1.0 Rydberg. Since ionization was found to occur with the emission of electrons of nearly zero kinetic energy, the fraction of ionizing collisions which result in capture decreases very rapidly with projectile kinetic energy. The energy distributions of slowed down muons and hadrons were also computed. These distributions were used together with the capture cross section to determine the distribution of kinetic energies at which capture takes place. It was found that most captures occur for kinetic energies slightly less than 1.0 Rydbergs with relatively little capture at thermal energies. The captured particles therefore tend to go into very large and loosely found orbits with binding energies less than 0.1 Rydbergs

    The radiative capture of negative muons by protons can be used to measure the weak induced pseudoscalar form factor. Brief arguments why this method is preferable to ordinary muon capture are given followed by a discussion of the experimental difficulties. The solution to these problems as attempted by experiment no. 452 at TRIUMF is presented together with preliminary results from the first run in August 1990. An outlook on the expected final precision and the experimental schedule is also given. (orig.)

  13. Capture by colour: evidence for dimension-specific singleton capture.

    2015-10-01

    Previous work on attentional capture has shown the attentional system to be quite flexible in the stimulus properties it can be set to respond to. Several different attentional "modes" have been identified. Feature search mode allows attention to be set for specific features of a target (e.g., red). Singleton detection mode sets attention to respond to any discrepant item ("singleton") in the display. Relational search sets attention for the relative properties of the target in relation to the distractors (e.g., redder, larger). Recently, a new attentional mode was proposed that sets attention to respond to any singleton within a particular feature dimension (e.g., colour; Folk & Anderson, 2010). We tested this proposal against the predictions of previously established attentional modes. In a spatial cueing paradigm, participants searched for a colour target that was randomly either red or green. The nature of the attentional control setting was probed by presenting an irrelevant singleton cue prior to the target display and assessing whether it attracted attention. In all experiments, the cues were red, green, blue, or a white stimulus rapidly rotated (motion cue). The results of three experiments support the existence of a "colour singleton set," finding that all colour cues captured attention strongly, while motion cues captured attention only weakly or not at all. Notably, we also found that capture by motion cues in search for colour targets was moderated by their frequency; rare motion cues captured attention (weakly), while frequent motion cues did not.

    Despite the importance of health facility capacity to provide comprehensive care, the most widely used indicators for global monitoring of maternal and child health remain contact measures which assess women's use of services only and not the capacity of health facilities to provide those services; there is a gap in monitoring health facilities' capacity to provide newborn care services in low and middle income countries. In this study we demonstrate a measurable framework for assessing health facility capacity to provide newborn care using open access, nationally-representative Service Provision Assessment (SPA) data from the Demographic Health Surveys Program. In particular, we examine whether key newborn-related services are available at the facility (ie, service availability, measured by the availability of basic emergency obstetric care (BEmOC) signal functions, newborn signal functions, and routine perinatal services), and whether the facility has the equipment, medications, training and knowledge necessary to provide those services (ie, service readiness, measured by general facility requirements, equipment, medicines and commodities, and guidelines and staffing) in five countries with high levels of neonatal mortality and recent SPA data: Bangladesh, Haiti, Malawi, Senegal, and Tanzania. In each country, we find that key services and commodities needed for comprehensive delivery and newborn care are missing from a large percentage of facilities with delivery services. Of three domains of service availability examined, scores for routine care availability are highest, while scores for newborn signal function availability are lowest. Of four domains of service readiness examined, scores for general requirements and equipment are highest, while scores for guidelines and staffing are lowest. Both service availability and readiness tend to be highest in hospitals and facilities in urban areas, pointing to substantial equity gaps in the availability of essential

  15. CHAOTIC CAPTURE OF NEPTUNE TROJANS

    2009-01-01

    Neptune Trojans (NTs) are swarms of outer solar system objects that lead/trail planet Neptune during its revolutions around the Sun. Observations indicate that NTs form a thick cloud of objects with a population perhaps ∼10 times more numerous than that of Jupiter Trojans and orbital inclinations reaching ∼25 deg. The high inclinations of NTs are indicative of capture instead of in situ formation. Here we study a model in which NTs were captured by Neptune during planetary migration when secondary resonances associated with the mean-motion commensurabilities between Uranus and Neptune swept over Neptune's Lagrangian points. This process, known as chaotic capture, is similar to that previously proposed to explain the origin of Jupiter's Trojans. We show that chaotic capture of planetesimals from an ∼35 Earth-mass planetesimal disk can produce a population of NTs that is at least comparable in number to that inferred from current observations. The large orbital inclinations of NTs are a natural outcome of chaotic capture. To obtain the ∼4:1 ratio between high- and low-inclination populations suggested by observations, planetary migration into a dynamically excited planetesimal disk may be required. The required stirring could have been induced by Pluto-sized and larger objects that have formed in the disk.

    The 12 January 2010 earthquake in Haiti demonstrates the necessity of understanding information communication between disciplines during disasters. Armed with data from a variety of sources, from geophysics to construction, water and sanitation to education, decision makers can initiate well-informed policies to reduce the risk from future hazards. At the core of this disaster was a natural hazard that occurred in an environmentally compromised country. The earthquake itself was not solely responsible for the magnitude of the disaster- poor construction practices precipitated by extreme poverty, a two centuries of post-colonial environmental degradation and a history of dysfunctional government shoulder much of the responsibility. Future policies must take into account the geophysical reality that future hazards are inevitable and may occur within the very near future, and how various institutions will respond to the stressors. As the global community comes together in reconstruction efforts, it is necessary for the various actors to take into account what vulnerabilities were exposed by the earthquake, most vividly seen during the initial response to the disaster. Responders are forced to prioritize resources designated for building collapse and infrastructure damage, delivery of critical services such as emergency medical care, and delivery of food and water to those in need. Past disasters have shown that communication lapses between the response and recovery phases results in many of the exposed vulnerabilities not being adequately addressed, and the recovery hence fails to bolster compromised systems. The response reflects the basic characteristics of a Complex Adaptive System, where new agents emerge and priorities within existing organizations shift to deal with new information. To better understand how information is shared between actors during this critical transition, we are documenting how information is communicated between critical sectors during the

    Haiti has the highest human rabies burden in the Western Hemisphere. There is no published literature describing the public's perceptions of rabies in Haiti, information that is critical to developing effective interventions and government policies. We conducted a knowledge, attitudes and practices survey of 550 community members and 116 health professionals in Pétionville, Haiti in 2013 to understand the perception of rabies in these populations. The majority of respondents (85%) knew that dogs were the primary reservoir for rabies, yet only 1% were aware that bats and mongooses could transmit rabies. Animal bites were recognized as a mechanism of rabies transmission by 77% of the population and 76% were aware that the disease could be prevented by vaccination. Of 172 persons reporting a bite, only 37% sought medical treatment. The annual bite incidence rate in respondents was 0·9%. Only 31% of bite victims reported that they started the rabies vaccination series. Only 38% of respondents reported that their dog had been vaccinated against rabies. The majority of medical professionals recognized that dogs were the main reservoir for rabies (98%), but only 28% reported bats and 14% reported mongooses as posing a risk for rabies infection. Bites were reported as a mechanism of rabies transmission by 73% of respondents; exposure to saliva was reported by 20%. Thirty-four percent of medical professionals reported they would wash a bite wound with soap and water and 2·8% specifically mentioned rabies vaccination as a component of post-bite treatment. The majority of healthcare professionals recommended some form of rabies assessment for biting animals; 68·9% recommended a 14-day observation period, 60·4% recommended a veterinary consultation, and 13·2% recommended checking the vaccination status of the animal. Fewer than 15% of healthcare professionals had ever received training on rabies prevention and 77% did not know where to go to procure rabies vaccine for

    A remote sensing technique was developed which combines a Geographic Information System (GIS); Google Earth, and Microsoft Excel to identify home locations for a random sample of households in rural Haiti. The method was used to select homes for ethnographic and water quality research in a region of rural Haiti located within 9 km of a local hospital and source of health education in Deschapelles, Haiti. The technique does not require access to governmental records or ground based surveys to collect household location data and can be performed in a rapid, cost-effective manner. The random selection of households and the location of these households during field surveys were accomplished using GIS, Google Earth, Microsoft Excel, and handheld Garmin GPSmap 76CSx GPS units. Homes were identified and mapped in Google Earth, exported to ArcMap 10.0, and a random list of homes was generated using Microsoft Excel which was then loaded onto handheld GPS units for field location. The development and use of a remote sensing method was essential to the selection and location of random households. A total of 537 homes initially were mapped and a randomized subset of 96 was identified as potential survey locations. Over 96% of the homes mapped using Google Earth imagery were correctly identified as occupied dwellings. Only 3.6% of the occupants of mapped homes visited declined to be interviewed. 16.4% of the homes visited were not occupied at the time of the visit due to work away from the home or market days. A total of 55 households were located using this method during the 10 days of fieldwork in May and June of 2012. The method used to generate and field locate random homes for surveys and water sampling was an effective means of selecting random households in a rural environment lacking geolocation infrastructure. The success rate for locating households using a handheld GPS was excellent and only rarely was local knowledge required to identify and locate households. This

    Antimalarial drugs are a key tool in malaria elimination programs. With the emergence of artemisinin resistance in southeast Asia, an effort to identify molecular markers for surveillance of resistant malaria parasites is underway. Non-synonymous mutations in the kelch propeller domain (K13-propeller) in Plasmodium falciparum have been associated with artemisinin resistance in samples from southeast Asia, but additional studies are needed to characterize this locus in other P. falciparum populations with different levels of artemisinin use. Here, we sequenced the K13-propeller locus in 82 samples from Haiti, where limited government oversight of non-governmental organizations may have resulted in low-level use of artemisinin-based combination therapies. We detected a single-nucleotide polymorphism (SNP) at nucleotide 1,359 in a single isolate. Our results contribute to our understanding of the global genomic diversity of the K13-propeller locus in P. falciparum populations. PMID:25646258

  5. CO2 Capture and Reuse

    CO2 capture and storage including its utilization or reuse presents an opportunity to achieve deep reductions in greenhouse gas emissions from fossil energy use. The development and deployment of this option could significantly assist in meeting a future goal of achieving stabilization of the presently rising atmospheric concentration of greenhouse gases. CO2 capture from process streams is an established concept that has achieved industrial practice. Examples of current applications include the use of primarily, solvent based capture technologies for the recovery of pure CO2 streams for chemical synthesis, for utilization as a food additive, for use as a miscible agent in enhanced oil recovery operations and removal of CO2 as an undesired contaminant from gaseous process streams for the production of fuel gases such as hydrogen and methane. In these applications, the technologies deployed for CO2 capture have focused on gas separation from high purity, high pressure streams and in reducing (or oxygen deficient) environments, where the energy penalties and cost for capture are moderately low. However, application of the same capture technologies for large scale abatement of greenhouse gas emissions from fossil fuel use poses significant challenges in achieving (at comparably low energy penalty and cost) gas separation in large volume, dilute concentration and/or low pressure flue gas streams. This paper will focus on a review of existing commercial methods of CO2 capture and the technology stretch, process integration and energy system pathways needed for their large scale deployment in fossil fueled processes. The assessment of potential capture technologies for the latter purpose will also be based on published literature data that are both 'transparent' and 'systematic' in their evaluation of the overall cost and energy penalties of CO2 capture. In view of the of the fact that many of the existing commercial processes for CO2 capture have seen applications in

    There is unmet contraceptive need among Haitian immigrants and Haitian-American women (Haitian women). The study explored associations of three measures of acculturation with contraceptive/reproductive health history among Haitian women residing in the Little Haiti community of Miami. This was a cross-sectional, exploratory study among 57 Haitian women. We conducted descriptive univariate analyses, then bivariate analyses to investigate the association of acculturation with reproductive health risk behavior including contraceptive use, tampon use, and parity, as well as interest in a female-initiated barrier contraceptive method. The most commonly ever-used contraceptive methods were male condoms (78.9 %) and oral contraceptives (OC 19.3 %). Women who primarily spoke Créole at home were less likely than those who did not to use OC (11.9 vs. 42.9 %, p = .01). Among women who resided in the U.S. ≥10 years, tampon use was 51.9 % compared to 16.7 % among those who were in the U.S. for less time (p = .005). Among U.S. born women, 60 % were tampon users compared to 22.7 % among those born in Haiti (p = .05). Women not speaking primarily Créole at home (p = .06) and those born in U.S. (p = .008) had fewer children. Contraceptive use was low among Haitian women but influenced by acculturation, where greater acculturation was associated with protective reproductive health behavior. Despite traditional norms discouraging contraceptive use, and little experience with female barriers, Haitian women indicated an interest in learning about and using a female-initiated barrier contraceptive. Increasing contraceptive uptake of potential multipurpose technologies is a potential point of intervention for decreasing HIV/STI transmission in this at-risk population.

    The Haiti earthquake in 2010 resulted in 1.5 million internally displaced people (IDP), yet little is known about the impact of displacement on health. In this study, we estimate the impact of displacement on infant and child mortality and key health-behavior mechanisms. We employ a difference-in-differences (DID) design with coarsened exact matching (CEM) to ensure comparability among groups with different displacement status using the 2012 Haiti Demographic and Health Survey (DHS). The participants are 21,417 births reported by a nationally representative sample of 14,287 women aged 15-49. The main independent variables are household displacement status which includes households living in camps, IDP households (not in camps), and households not displaced. The main outcomes are infant and child mortality; health status (height-for-age, anemia); uptake of public health interventions (bed net use, spraying against mosquitoes, and vaccinations); and other conditions (hunger; cholera). Births from the camp households have higher infant mortality (OR = 2.34, 95 % CI 1.15 to 4.75) and child mortality (OR = 2.34, 95 % CI 1.10 to 5.00) than those in non-camp IDP households following the earthquake. These odds are higher despite better access to food, water, bed net use, mosquito spraying, and vaccines among camp households. IDP populations are heterogeneous and households that are displaced outside of camps may be self-selected or self-insured. Meanwhile, even households not displaced by a disaster may face challenges in access to basic necessities and health services. Efforts are needed to identify vulnerable populations to provide targeted assistance in post-disaster relief.

    Since their adoption in 2000 by the United Nations, the Millennium Development Goals set for 2015 appear to have become a part of the policy agenda of all of the member states. Three of these eight objectives deal with health issues. "Combat HIV/AIDS, malaria and other diseases": this is the formulation of the sixth MDG. Observing that in many countries strongly affected by poverty and inequalities, the epidemic continues to spread, without really reversing at all, and that access to antiretrovirals is possible for only a small proportion of the patient who need them, we consider the problems of global governance in the field of health. Our intention is to explain that the failure to deal with the HIV/AIDS epidemic may constitute an obstacle to the achievement of the MDGs by 2015. Proposing a comprehensive sociology of HIV/AIDS, this article pays special attention to the dimension of the meaning of the disease, simultaneously as a policy issue, a social construction, and an object of study in the social sciences. Looking at the two countries most affected by the epidemic in Africa and in the Caribbean, we examine the different aspects that have determined the failure of governance and the effects of this failure on the populations concerned. The excessive conflictuality in South Africa and the biopolitics of "let them die" and the fragmentation of the networks involved in the combat in Haiti are considered to have contributed to a crisis in the epidemic's governance. In both cases, the consequences have been expressed by a reduced life expectancy, insufficient access to antiretroviral drugs, reinforcement of the socioeconomic inequalities of health, the production of new pockets of poverty, more fragile household and national economies, an increase in maternal and child mortality ... The failure of the governance of the HIV/AIDS epidemic in countries such as Haiti and South Africa appears to foretell the impossibility of achieving the MDGs by 2015.

    Haiti has historically vaccinated between 100,000 and 300,000 dogs annually against rabies, however national authorities have not been able to reach and maintain the 70% coverage required to eliminate the canine rabies virus variant. Haiti conducts massive dog vaccination campaigns on an annual basis and utilizes both central point and door-to-door methods. These methods require that dog owners are aware of the dates and locations of the campaign. To improve this awareness among dog owners, 600,000 text messages were sent to phones in two Haitian communes (Gonaives and Saint-Marc) to remind dog owners to attend the campaign. Text messages were delivered on the second day and at the mid-point of the campaign. A post-campaign household survey was conducted to assess dog owner's perception of the text messages and the impact on their participation in the vaccination campaign. Overall, 147 of 160 (91.9%) text-receiving dog owners indicated the text was helpful, and 162 of 187 (86.6%) responding dog owners said they would like to receive text reminders during future rabies vaccination campaigns. In areas hosting one-day central point campaigns, dog owners who received the text were 2.0 (95% CI 1.1, 3.6) times more likely to have participated in the campaign (73.1% attendance among those who received the text vs 36.4% among those who did not). In areas incorporating door-to-door vaccination over multiple days there was no significant difference in participation between dog owners who did and did not receive a text. Text message reminders were well-received and significantly improved campaign attendance, indicating that short message service (SMS) alerts may be a successful strategy in low resource areas with large free roaming dog populations.

    Full Text Available Abstract Background Microsatellite markers have proven useful in genetic studies in many organisms, yet microsatellite-based studies of the dengue and yellow fever vector mosquito Aedes aegypti have been limited by the number of assayable and polymorphic loci available, despite multiple independent efforts to identify them. Here we present strategies for efficient identification and development of useful microsatellites with broad coverage across the Aedes aegypti genome, development of multiplex-ready PCR groups of microsatellite loci, and validation of their utility for population analysis with field collections from Haiti. Results From 79 putative microsatellite loci representing 31 motifs identified in 42 whole genome sequence supercontig assemblies in the Aedes aegypti genome, 33 microsatellites providing genome-wide coverage amplified as single copy sequences in four lab strains, with a range of 2-6 alleles per locus. The tri-nucleotide motifs represented the majority (51% of the polymorphic single copy loci, and none of these was located within a putative open reading frame. Seven groups of 4-5 microsatellite loci each were developed for multiplex-ready PCR. Four multiplex-ready groups were used to investigate population genetics of Aedes aegypti populations sampled in Haiti. Of the 23 loci represented in these groups, 20 were polymorphic with a range of 3-24 alleles per locus (mean = 8.75. Allelic polymorphic information content varied from 0.171 to 0.867 (mean = 0.545. Most loci met Hardy-Weinberg expectations across populations and pairwise FST comparisons identified significant genetic differentiation between some populations. No evidence for genetic isolation by distance was observed. Conclusion Despite limited success in previous reports, we demonstrate that the Aedes aegypti genome is well-populated with single copy, polymorphic microsatellite loci that can be uncovered using the strategy developed here for rapid and efficient

    The cost of traumatic injury is unknown in Haiti. This study aims to examine the burden of traumatic injury of patients treated and evaluated at a trauma hospital in the capital city of Port-au-Prince. A retrospective cross-sectional chart review study was conducted at the Hospital Bernard Mevs Project Medishare for all patients evaluated for traumatic injury from December 2015 to January 2016, as described elsewhere (Zuraik and Sampalis in World J Surg, https://doi.org/10.1007/s00268-017-4088-2 , 2017). Direct medical costs were obtained from patient hospital bills. Indirect and intangible costs were calculated using the human capital approach. A total of 410 patients were evaluated for traumatic injury during the study period. Total costs for all patients were $501,706 with a mean cost of $1224. Indirect costs represented 63% of all costs, direct medical costs 19%, and intangible costs 18%. Surgical costs accounted for the majority of direct medical costs (29%). Patients involved in road traffic accidents accounted for the largest number of injuries (41%) and the largest percentage of total costs (51%). Patients with gunshot wounds had the highest total mean costs ($1566). Mean costs by injury severity ranged from $62 for minor injuries, $1269 for serious injuries, to $13,675 for critical injuries. Injuries lead to a significant economic burden for individuals treated at a semi-private trauma hospital in the capital city of Port-au-Prince, Haiti. Programs aimed at reducing injuries, particularly road traffic accidents, would likely reduce the economic burden to the nation.

    Consumption of drinking water from private vendors has increased considerably in Port-au-Prince, Haiti, in recent decades. A major type of vendor is private kiosks, advertising reverse osmosis-treated water for sale by volume. To describe the scale and geographical distribution of private kiosks in metropolitan Port-au-Prince, an inventory of private kiosks was conducted from July to August 2013. Coordinates of kiosks were recorded with global positioning system units and a brief questionnaire was administered with the operator to document key kiosk characteristics. To assess the quality of water originating from private kiosks, water quality analyses were also conducted on a sample of those inventoried as well as from the major provider company sites. The parameters tested were Escherichia coli , free chlorine residual, pH, turbidity, and total dissolved solids. More than 1,300 kiosks were inventoried, the majority of which were franchises of four large provider companies. Approximately half of kiosks reported opening within 12 months of the date of the inventory. The kiosk treatment chain and sales price was consistent among a majority of the kiosks. Of the 757 kiosks sampled for water quality, 90.9% of samples met World Health Organization (WHO) microbiological guideline at the point of sale for nondetectable E. coli in a 100-mL sample. Of the eight provider company sites tested, all samples met the WHO microbiological guideline. Because of the increasing role of the private sector in drinking water provision in Port-au-Prince and elsewhere in Haiti, this assessment was an important first step for government regulation of this sector.

    The MW 7.0, 12 January 2010, Haiti earthquake triggered more than 7,000 landslides in the mountainous terrain south of Port-au-Prince over an area that extends approximately 50 km to the east and west from the epicenter and to the southern coast. Most of the triggered landslides were rock and soil slides from 25°–65° slopes within heavily fractured limestone and deeply weathered basalt and basaltic breccia. Landslide volumes ranged from tens of cubic meters to several thousand cubic meters. Rock slides in limestone typically were 2–5 m thick; slides within soils and weathered basalt typically were less than 1 m thick. Twenty to thirty larger landslides having volumes greater than 10,000 m3 were triggered by the earthquake; these included block slides and rotational slumps in limestone bedrock. Only a few landslides larger than 5,000 m3 occurred in the weathered basalt. The distribution of landslides is asymmetric with respect to the fault source and epicenter. Relatively few landslides were triggered north of the fault source on the hanging wall. The densest landslide concentrations lie south of the fault source and the Enriquillo-Plantain-Garden fault zone on the footwall. Numerous landslides also occurred along the south coast west of Jacmél. This asymmetric distribution of landsliding with respect to the fault source is unusual given the modeled displacement of the fault source as mainly thrust motion to the south on a plane dipping to the north at approximately 55°; landslide concentrations in other documented thrust earthquakes generally have been greatest on the hanging wall. This apparent inconsistency of the landslide distribution with respect to the fault model remains poorly understood given the lack of any strong-motion instruments within Haiti during the earthquake.

    Human immunodeficiency virus (HIV) infection has been postulated to alter the natural history of cholera, including increased susceptibility to infection, severity of illness, and chronic carriage of Vibrio cholerae Haiti has a generalized HIV epidemic with an adult HIV prevalence of 1.9% and recently suffered a cholera epidemic. We conducted a prospective study at the cholera treatment center (CTC) of GHESKIO in Haiti to characterize the coinfection. Adults admitted at the CTC for acute diarrhea were invited to participate in the study. Vital signs, frequency, and volume of stools and/or vomiting were monitored, and single-dose doxycycline was administered. After counseling, participants were screened for HIV by enzyme-linked immunosorbent assay and for cholera by culture. Of 729 adults admitted to the CTC, 99 (13.6%) had HIV infection, and 457 (63%) had culture-confirmed cholera. HIV prevalence was three times higher in patients without cholera (23%, 63/272) than in those with culture-confirmed cholera (7.9%, 36/457). HIV prevalence in patients with culture-confirmed cholera (7.9%) was four times higher than the adult prevalence in Port-au-Prince (1.9%). Of the 36 HIV-infected patients with cholera, 25 (69%) had moderate/severe dehydration versus 302/421 (72%) in the HIV negative. Of 30 HIV-infected patients with weekly stool cultures performed after discharge, 29 (97%) were negative at week 1. Of 50 HIV-negative patients with weekly stool cultures, 49 (98%) were negative at week 1. In countries with endemic HIV infection, clinicians should consider screening patients presenting with suspected cholera for HIV coinfection. © The American Society of Tropical Medicine and Hygiene.

    The Mw 7.0 January 2010 earthquake in Haiti was one of the deadliest in history. It involved multiple faults along or near the main Enriquillo-Plantain Garden Fault (EPGF). This left-lateral transform is a branch of the northern Caribbean plate boundary across southern Hispaniola. The main rupture was strike-slip but almost all aftershocks had thrust mechanisms, and surface deformation may have been concentrated on anticline forelimbs driven by blind thrust faults. Earthquake generated mass-wasting and turbidity currents were sampled from the Canal du Sud slope (~1000 m water depth), a basin at 1500 m, and the deepest part of the strait at 1700 m. The turbidites were strongly correlated by 234Th with a half-life of 24 days. In the deepest area, a turbidite-homogenite unit (T-H) extends over 50 km2 and is composed of basal sand beds 5 cm thick and 50 cm of mud above. The sedimentary structures in the sand were linked to oscillatory motions by internal seiches. The T-H units recovered from the slope and deep basin are similar in composition. The Leogane Delta, upslope from the sampling sites, is rich in this lithology that has been linked to oceanic basement rocks exposed on the southern Haitian peninsula. In contrast, the T-H unit recovered from the basin at 1500 m is perched behind a thrust anticline and has a greater concentration of Ca derived from Ca rich sources such as the Tapion Ridge on the southern peninsula. The Tapion Ridge is a compressional structure associated with a restraining bend along the EPGF. The T-H unit beneath the 2010 deposit has a 14C age of 2400 cal yrs BP, and interpreted as an earthquake triggered deposit. It is nearly identical in thickness, composition and fine structures to the 2010 T-H. Notably absent from the record are younger turbidites that could have been linked to the historic 1770 AD and other similar earthquakes expected from GPS rates across the EPGF. Two hypotheses are being considered for this long gap in T-H sedimentation

    Since Early Paleogene times, the North Caribbean plate is colliding obliquely with the south continental part of the old N. American Margins, which is represented by various segments from West to East, inherited from Jurassic times. Location, amount of displacement, rotation and the structural deformation of these margin segments, resulting from the dislocation of the continental N American margin, are not clearly yet established. At present, the plate limits are marked either by two left lateral faults west and inside Haiti (OSF in the North and EPGF in the South), oblique collision front (further west in Cuba), oblique subducted segments (to the East, Porto-Rico). From our recent works operated both offshore (Haiti-SIS and Haiti-BGF surveys 2012-2015) and onshore (field campaigns 2013-2017) in Haitian zone, the position of the present-day and paleo major limits have been redefined. These paleolimits have been reconstructed up to early Miocene times, based on: restoration of regional structural cross-sections, sedimentology and on paleoenvironement studies. In a preliminary way, we analyzed the complexity of the tectonic heritage with possible nature, heterogeneity of the crustal fragments and associated margins close to Haiti (age, structure, environment, location of the dislocated blocks through times) which profoundly impact the partitioning of the deformation along this complex transformed margin. The change in the structure wavelength, decollement level variations are primary constraints in the restoration of the main units and do impose a deep connection along specific segments either related to strike-slip or to splay faults. The asymmetry on the repartition of the fault activity tend to prove that the past motion related to "EPGF transfer zone" is mainly partitioned in Haiti to the North of the present-day EPGF position. At present, these results are still coherent with the distribution of the aftershoks registered after 2010, and with the present

    Artibonite Valley, a rural area in Haiti. To evaluate a tuberculosis control program in rural Haiti and to compare two strategies for treatment implemented in two areas that were not chosen at random: treatment delivered at the patients' homes observed by former tuberculosis patients (DOT), and non observed treatment (non-DOT). Retrospective analysis of the clinical records of adult patients diagnosed with tuberculosis at H pital Albert Schweitzer in Deschapelles, Haiti, during 1994-1995. There were 143 patients in the non-DOT group and 138 patients in the DOT group. The results of treatment were significantly different: in the non-DOT group 29% defaulted, 12% died and 58% had a successful outcome; in the DOT group 7% defaulted (P < 0.01), 4% died (P = 0.01) and 87% had a successful outcome (P < 0.01). These differences are also significant when considering only human immunodeficiency virus (HIV) infected patients (defaulted P < 0.01; died P = 0.09; successful outcome P < 0.01). Delivering treatment in patients' homes with direct observation by former tuberculosis patients can achieve good results, even in an area of extreme poverty and high rates of HIV infection. In this population the number of patients who are able to complete their treatment without observed administration is far from optimal.

    Social networking sites provide virtual environments in which individuals and organizations exchange real-time information on a multitude of topics, including health promotion and disease prevention. The January 2010 earthquake in Haiti has been posited as a turning point in the way in which organizations use social media, such as Twitter, for crisis communication. The purpose of this content analysis was to explore whether organizations' use of Twitter changed after the 2010 Haiti earthquake. A team of 13 coders analyzed all English-language tweets (N = 2,616) during the 3 months before and post earthquake from 6 leading organizations in the Haiti disaster relief efforts. Study findings indicate that the ways in which organizations used Twitter changed over time. Chi-square analyses demonstrated that organizations decreased in their use of certain strategies to disseminate information through Twitter, such as the use of links. Organizations did not change in their use of techniques to involve users (e.g., retweet, call to action), with the exception of using tweets as a fundraising mechanism. Study findings highlight missed opportunities among organizations to maximize Twitter in order to encourage more interactive and immediate communication with the global community.

    AbstractHaiti has the highest burden of rabies in the Western hemisphere, with 130 estimated annual deaths. We present the cost-effectiveness evaluation of an integrated bite case management program combining community bite investigations and passive animal rabies surveillance, using a governmental perspective. The Haiti Animal Rabies Surveillance Program (HARSP) was first implemented in three communes of the West Department, Haiti. Our evaluation encompassed all individuals exposed to rabies in the study area ( N = 2,289) in 2014-2015. Costs (2014 U.S. dollars) included diagnostic laboratory development, training of surveillance officers, operational costs, and postexposure prophylaxis (PEP). We used estimated deaths averted and years of life gained (YLG) from prevented rabies as health outcomes. HARSP had higher overall costs (range: $39,568-$80,290) than the no-bite-case-management (NBCM) scenario ($15,988-$26,976), partly from an increased number of bite victims receiving PEP. But HARSP had better health outcomes than NBCM, with estimated 11 additional annual averted deaths in 2014 and nine in 2015, and 654 additional YLG in 2014 and 535 in 2015. Overall, HARSP was more cost-effective (US$ per death averted) than NBCM (2014, HARSP: $2,891-$4,735, NBCM: $5,980-$8,453; 2015, HARSP: $3,534-$7,171, NBCM: $7,298-$12,284). HARSP offers an effective human rabies prevention solution for countries transitioning from reactive to preventive strategies, such as comprehensive dog vaccination.

    We assessed healthcare provider perspectives of international aid four years after the Haiti Earthquake to better understand the impact of aid on the Haitian healthcare system and learn best practices for recovery in future disaster contexts. We conducted 22 semi-structured interviews with the directors of local, collaborative, and aid-funded healthcare facilities in Leogane, Haiti. We coded and analysed the interviews using an iterative method based on a grounded theory approach of data analysis. Healthcare providers identified positive aspects of aid, including acute emergency relief, long-term improved healthcare access, and increased ease of referrals for low-income patients. However, they also identified negative impacts of international aid, including episodes of poor quality care, internal brain drain, competition across facilities, decrease in patient flow to local facilities, and emigration of Haitian doctors to abroad. As Haiti continues to recover, it is imperative for aid institutions and local healthcare facilities to develop a more collaborative relationship to transition acute relief to sustainable capacity building. In future disaster contexts, aid institutions should specifically utilise quality of care metrics, NGO Codes of Conduct, Master Health Facility Lists, and sliding scale payment systems to improve disaster response.

    This thesis discusses the main results of recent experimental studies of electron capture in asymmetric collisions. Most of the results have been published, but the thesis also contains yet unpublished data, or data presented only in unrefereed conference proceedings. The thesis aims at giving a coherent discussion of the understanding of the experimental results, based first on simple qualitative considerations and subsequently on quantitative comparisons with the best theoretical calculations currently available.

    The South African Triage Scale (SATS) has demonstrated good validity in the EDs of Médecins Sans Frontières (MSF)-supported sites in Afghanistan and Haiti; however, corresponding reliability in these settings has not yet been reported on. This study set out to assess the inter-rater and intrarater reliability of the SATS in four MSF-supported EDs in Afghanistan and Haiti (two trauma-only EDs and two mixed (including both medical and trauma cases) EDs). Under classroom conditions between December 2013 and February 2014, ED nurses at each site assigned triage ratings to a set of context-specific vignettes (written case reports of ED patients). Inter-rater reliability was assessed by comparing triage ratings among nurses; intrarater reliability was assessed by asking the nurses to retriage 10 random vignettes from the original set and comparing these duplicate ratings. Inter-rater reliability was calculated using the unweighted kappa, linearly weighted kappa and quadratically weighted kappa (QWK) statistics, and the intraclass correlation coefficient (ICC). Intrarater reliability was calculated according to the percentage of exact agreement and the percentage of agreement allowing for one level of discrepancy in triage ratings. The correlation between years of nursing experience and reliability of the SATS was assessed based on comparison of ICCs and the respective 95% CIs. A total of 67 nurses agreed to participate in the study: In Afghanistan there were 19 nurses from Kunduz Trauma Centre and nine from Ahmed Shah Baba; in Haiti, there were 20 nurses from Martissant Emergency Centre and 19 from Tabarre Surgical and Trauma Centre. Inter-rater agreement was moderate across all sites (ICC range: 0.50-0.60; QWK range: 0.50-0.59) apart from the trauma ED in Haiti where it was moderate to substantial (ICC: 0.58; QWK: 0.61). Intrarater agreement was similar across the four sites (68%-74% exact agreement); when allowing for a one-level discrepancy in triage ratings

    Executive Summary A field reconnaissance in Haiti by a five-member team with expertise in seismology and earthquake engineering has revealed a number of factors that led to catastrophic losses of life and property during the January 12, 2010, Mw 7.0 earthquake. The field study was conducted from January 26 to February 3, 2010, and included investigations in Port-au-Prince and the heavily damaged communities to the west, including Leogane, Grand Goave, Petite Goave, and Oliver. Seismology Despite recent seismic quiescence, Haiti has suffered similar devastating earthquakes in the historical past (1701, 1751, 1770 and 1860). Despite this knowledge of historical seismicity, Haiti had no seismograph stations during the main earthquake, so it is impossible to estimate accurately the intensity of ground motions. Nonetheless, the wide range of buildings damaged by the January 12, 2010, earthquake suggests that the ground motions contained seismic energy over a wide range of frequencies. Another earthquake of similar magnitude could strike at any time on the eastern end of the Enriquillo Fault, directly to the south of Port-au-Prince. Reconstruction must take this hazard into account. The four portable seismographs installed by the team recorded a series of small aftershocks. As expected, the ground motions recorded at a hard-rock site contained a greater proportion of high frequencies than the motions recorded at a soil site. Two of the stations continue to monitor seismic activity. A thorough field investigation of the mapped Enriquillo Fault south of the city of Leogane failed to find any evidence of surface faulting. This led the team to conclude that the earthquake was unlikely to have produced any surface rupture in the study area. Geotechnical Aspects Soil liquefaction, landslides and rockslides in cut slopes, and road embankment failures contributed to extensive damage in Port-au-Prince and elsewhere. A lack of detailed knowledge of the physical conditions of the

    Troester, Joseph W.; Turvey, Michael D.

    Île de la Gonâve is a 750-km2 island off the coast of Haiti. The depth to the water table ranges from less than 30 m in the Eocene and Upper Miocene limestones to over 60 m in the 300-m-thick Quaternary limestone. Annual precipitation ranges from 800-1,400 mm. Most precipitation is lost through evapotranspiration and there is virtually no surface water. Roughly estimated from chloride mass balance, about 4% of the precipitation recharges the karst aquifer. Cave pools and springs are a common source for water. Hand-dug wells provide water in coastal areas. Few productive wells have been drilled deeper than 60 m. Reconnaissance field analyses indicate that groundwater in the interior is a calcium-bicarbonate type, whereas water at the coast is a sodium-chloride type that exceeds World Health Organization recommended values for sodium and chloride. Tests for the presence of hydrogen sulfide-producing bacteria were negative in most drilled wells, but positive in cave pools, hand-dug wells, and most springs, indicating bacterial contamination of most water sources. Because of the difficulties in obtaining freshwater, the 110,000 inhabitants use an average of only 7 L per person per day. L'Île de la Gonâve est une île de 750 km2 au large de la côte d'Haïti. La profondeur de la nappe varie entre moins de 30 m dans les calcaires de l'Éocène et du Miocène supérieur à plus de 60 m dans les calcaires quaternaires épais de 300 m. Les précipitations annuelles sont comprises entre 800-1.400 mm. La plus grande partie des précipitations est perdue par évapotranspiration et il n'y a pratiquement pas d'eau de surface. Le bilan de masse des chlorures permet d'estimer à 4% des précipitations le montant de la recharge de l'aquifère karstique. Des bassins dans les grottes et des sources sont la source d'eau courante. Des puits creusés à la main fournissent de l'eau dans les zones côtières. Quelques puits productifs ont été forés dépassant 60 m de profondeur. L

  12. Realistic costs of carbon capture

    There is a growing interest in carbon capture and storage (CCS) as a means of reducing carbon dioxide (CO2) emissions. However there are substantial uncertainties about the costs of CCS. Costs for pre-combustion capture with compression (i.e. excluding costs of transport and storage and any revenue from EOR associated with storage) are examined in this discussion paper for First-of-a-Kind (FOAK) plant and for more mature technologies, or Nth-of-a-Kind plant (NOAK). For FOAK plant using solid fuels the levelised cost of electricity on a 2008 basis is approximately 10 cents/kWh higher with capture than for conventional plants (with a range of 8-12 cents/kWh). Costs of abatement are found typically to be approximately US$150/tCO2 avoided (with a range of US$120-180/tCO2 avoided). For NOAK plants the additional cost of electricity with capture is approximately 2-5 cents/kWh, with costs of the range of US$35-70/tCO2 avoided. Costs of abatement with carbon capture for other fuels and technologies are also estimated for NOAK plants. The costs of abatement are calculated with reference to conventional SCPC plant for both emissions and costs of electricity. Estimates for both FOAK and NOAK are mainly based on cost data from 2008, which was at the end of a period of sustained escalation in the costs of power generation plant and other large capital projects. There are now indications of costs falling from these levels. This may reduce the costs of abatement and costs presented here may be 'peak of the market' estimates. If general cost levels return, for example, to those prevailing in 2005 to 2006 (by which time significant cost escalation had already occurred from previous levels), then costs of capture and compression for FOAK plants are expected to be US$110/tCO2 avoided (with a range of US$90-135/tCO2 avoided). For NOAK plants costs are expected to be US$25-50/tCO2. Based on these considerations a likely representative range of costs of abatement from CCS

    We address the potential for energy conversions and capture for: energy generation; reduction in energy use; reduction in greenhouse gas emissions; remediation of water and air pollution; protection and enhancement of soil fertility. These processes have the potential to sequester carbon at scales that may have global impact. Energy conversion and capture strategies evaluate energy use and production from agriculture, urban areas and industries, and apply existing and emerging technologies to reduce and recapture energy embedded in waste products. The basis of biocrude production from Micro-algal feedstocks: 1) The nutrients from the liquid fraction of waste streams are concentrated and fed into photo bioreactors (essentially large vessels in which microalgae are grown) along with CO2 from flue gasses from down stream processes. 2) The algae are processed to remove high value products such as proteins and beta-carotenes. The advantage of algae feedstocks is the high biomass productivity is 30-50 times that of land based crops and the remaining biomass contains minimal components that are difficult to convert to biocrude. 3) The remaining biomass undergoes hydrothermal liquefaction to produces biocrude and biochar. The flue gasses of this process can be used to produce electricity (fuel cell) and subsequently fed back into the photobioreactor. The thermal energy required for this process is small, hence readily obtained from solar-thermal sources, and furthermore no drying or preprocessing is required keeping the energy overhead extremely small. 4) The biocrude can be upgraded and refined as conventional crude oil, creating a range of liquid fuels. In principle this process can be applied on the farm scale to the municipal scale. Overall, our primary food production is too dependent on fossil fuels. Energy conversion and capture can make food production sustainable.

    Haiti's national nutrition policy prioritises breastfeeding, but limited data are available to inform strategy. We examined national trends in early initiation of breastfeeding (ErIBF) and exclusive breastfeeding (EBF) over a 10-year period using data from three Haitian Demographic and Health Surveys (1994-1995, 2000 and 2005-2006). We used multivariate regression methods to identify determinants of ErIBF and EBF in the 2005-2006 data set and to examine relationships to growth. There was no change in ErIBF across surveys [1994-1995: 36.6%, 95% confidence interval (CI) 29.9-43.9; 2000: 49.4%, 95% CI 44.1-54.8; 2005-2006: 43.8%, 95% CI 40.5-47.1]. EBF among 0-5-month-olds increased sharply (1994-18995: 1.1%, 95% CI 0.4-3.2; 2000: 22.4%, 95% CI 16.5-29.5; 2005-2006: 41.2%, 95% CI 35.4-47.2). The proportion of breastfeeding children 0-5 months who received soft, solid or semi-solid foods decreased (1994-1995: 68.5%, 95% CI 57.3-77.9; 2000: 46.3%, 95% CI 39.3-53.4; 2005-2006: 30.9%, 95% CI 25.9-36.5). Child age at time of survey [odds ratio (OR) 1.73; P = 0.027], lower maternal education (OR = 2.14, P = 0.004) and residence in the Artibonite Department (OR 0.31; P = 0.001) were associated with ErIBF among children 0-23 months. Age group and department were significant predictors of EBF among children 0-5 months. ErIBF was associated with higher weight-for-age z-scores [effect size (ES) 0.22; P = 0.033] and height-for-age z-scores (ES 0.20; P = 0.044). There was no statistically significant relationship between EBF and growth. The 10-year ErIBF and EBF trends in Haiti echo global and regional trends. ErIBF and EBF are related practices but with different determinants in the Haitian context. These differences have implications for intervention delivery. © 2013 John Wiley & Sons Ltd.

    Public health measures are poised for transition from malaria control to malaria elimination on the island of Hispaniola. Assessment of the reservoir of asymptomatic infections from which acute malaria cases may derive is critical to plan and evaluate elimination efforts. Current field technology is ill suited for detecting sub-microscopic infections, thus highly sensitive survey methods capable of detecting virtually all infections are needed. In this study the prevalence of infection with Plasmodium falciparum was determined in patients seeking medical care primarily for non-febrile conditions in six departments in Haiti using a newly designed qRT-PCR-based assay. Three different methods of parasite detection were compared to assess their utility in approximating the prevalence of P. falciparum infections in the population: malaria rapid diagnostic test (RDT) designed to detect histidine-rich protein 2 (HRP2), thick smear microscopy, and a quantitative reverse transcription polymerase chain reaction (qRT-PCR) assay based upon the small sub-unit ribosomal RNA. The limit of detection of the qRT-PCR assay utilized was 0.0003 parasite/µL of blood. Venous blood was obtained from a total of 563 subjects from six departments in Haiti, all of whom were seeking medical attention without complaints consistent with malaria. Each subject was questioned for knowledge and behaviour using demographic and epidemiological survey to identify risk factors for disease transmission. Among the 563 samples tested, ten and 16 were found positive for malaria by RDT and microscopy, respectively. Using the qRT-PCR test to assess the infection status of these subjects, an additional 92 were identified for a total of 108. Based upon the qRT-PCR assay results, a wide variation in prevalence of infection in asymptomatic subjects was seen between geographic locations ranging from 4-41%. The prevalence of infection was highest in the Grand Anse, Nord and Sud-Est Departments, and demographic

    The Haiti earthquake occurred on tuesday, January 12, 2010 at 21:53:10 UTC. Its epicenter was at 18.46 degrees North, 72.53 degrees West, about 25 km WSW of Haiti's capital, Port-au-Prince. The earthquake was relatively shallow (H=13 km, U.S. Geological Survey) and thus had greater intensity and destructiveness. The earthquake occurred along the tectonic boundary between Caribbean and North America plate. This plate boundary is dominated by left-lateral strike slip motion and compression with 2 cm/year of slip velocity eastward with respect to the North America plate. The moment magnitude was measured to be 7.0 (U.S. Geological Survey) and 7.1 (Harvard Centroid-Moment-Tensor (CMT). More than 10 aftershocks ranging from 5.0 to 5.9 in magnitude (none of magnitude larger than 6.0) struck the area in hours following the main shock. Most of these aftershocks have occurred to the West of the mainshock in the Mirogoane Lakes region and its distribution suggests that the length of the rupture was around 70 km. The Harvard Centroid Moment Tensor (CMT) mechanism solution indicates lefth-lateral strike slip movement with a fault plane trending toward (strike = 251o ; dip = 70o; rake = 28o). In order to obtain the spatiotemporal slip distribution of a finite rupture model we have used teleseismic body wave and the Kikuchi and Kanamori's method [1]. Rupture velocity was constrained by using the directivity effect determined from a set of waveforms well recorded at regional and teleseismic distances [2]. Finally, we compared a map of aftershocks with the Coulomb stress changes caused by the event in the region [3]. [1]- Kikuchi, M., and Kanamori, H., 1982, Inversion of complex body waves: Bull.

    Between April and June, 2012, a reactive cholera vaccination campaign was done in Haiti with an oral inactivated bivalent whole-cell vaccine. We aimed to assess the effectiveness of the vaccine in a case-control study and to assess the likelihood of bias in that study in a bias-indicator study. Residents of Bocozel or Grand Saline who were eligible for the vaccination campaign (ie, age ≥12 months, not pregnant, and living in the region at the time of the vaccine campaign) were included. In the primary case-control study, cases had acute watery diarrhoea, sought treatment at one of three participating cholera treatment units, and had a stool sample positive for cholera by culture. For each case, four control individuals who did not seek treatment for acute watery diarrhoea were matched by location of residence, enrolment time (within 2 weeks of the case), and age (1-4 years, 5-15 years, and >15 years). Cases in the bias-indicator study were individuals with acute watery diarrhoea with a negative stool sample for cholera. Controls were selected in the same manner as in the primary case-control study. Trained staff used standard laboratory procedures to do rapid tests and stool cultures from study cases. Participants were interviewed to collect data on sociodemographic characteristics, risk factors for cholera, and self-reported vaccination. Data were analysed by conditional logistic regression, adjusting for matching factors. From Oct 24, 2012, to March 9, 2014, 114 eligible individuals presented with acute watery diarrhoea and were enrolled, 25 of whom were subsequently excluded. 47 participants were analysed as cases in the vaccine effectiveness case-control study and 42 as cases in the bias-indicator study. 33 (70%) of 47 cholera cases self-reported vaccination versus 167 (89%) of 188 controls (vaccine effectiveness 63%, 95% CI 8-85). 27 (57%) of 47 cases had certified vaccination versus 147 (78%) of 188 controls (vaccine effectiveness 58%, 13-80).

    Poverty and infectious diseases interact in complex ways. Casting destitution as intractable, or epidemics that afflict the poor as accidental, erroneously exonerates us from responsibility for caring for those most in need. Adequately addressing communicable diseases requires a biosocial appreciation of the structural forces that shape disease patterns. Most health interventions in resource-poor settings could garner support based on cost/benefit ratios with appropriately lengthy time horizons to capture the return on health investments and an adequate accounting of externalities; however, such a calculus masks the suffering of inaction and risks eroding the most powerful incentive to act: redressing inequality.

    Full Text Available The Centre Block of Canada’s Parliament buildings, National Historic Site of Canada is set to undergo a major rehabilitation project that will take approximately 10 years to complete. In preparation for this work, Heritage Conservation Services (HCS of Public Services and Procurement Canada has been completing heritage documentation of the entire site which includes laser scanning of all interior rooms and accessible confined spaces such as attics and other similar areas. Other documentation completed includes detailed photogrammetric documentation of rooms and areas of high heritage value. Some of these high heritage value spaces present certain challenges such as accessibility due to the height and the size of the spaces. Another challenge is the poor lighting conditions, requiring the use of flash or strobe lighting to either compliment or completely eliminate the available ambient lighting. All the spaces captured at this higher level of detail were also captured with laser scanning. This allowed the team to validate the information and conduct a quality review of the photogrammetric data. As a result of this exercise, the team realized that in most, if not all cases, the photogrammetric data was more detailed and at a higher quality then the terrestrial laser scanning data. The purpose and motivation of this paper is to present these findings, as well provide the advantages and disadvantages of the two methods and data sets.

    A method is introduced that can directly acquire knowledge-engineered, rule-based logic in an adaptive network. This adaptive representation of the rule system can then replace the rule system in simulated intelligent agents and thereby permit further performance-based adaptation of the rule system. The approach described provides both weight-fitting network adaptation and potentially powerful rule mutation and selection mechanisms. Nonlinear terms are generated implicitly in the mutation process through the emergent interaction of multiple linear terms. By this method it is possible to acquire nonlinear relations that exist in the training data without addition of hidden layers or imposition of explicit nonlinear terms in the network. We smoothed and captured a set of expert rules with an adaptive network. The motivation for this was to (1) realize a speed advantage over traditional rule-based simulations; (2) have variability in the intelligent objects not possible by rule-based systems but provided by adaptive systems: and (3) maintain the understandability of rule-based simulations. A set of binary rules was smoothed and converted into a simple set of arithmetic statements, where continuous, non-binary rules are permitted. A neural network, called the expert network, was developed to capture this rule set, which it was able to do with zero error. The expert network is also capable of learning a nonmonotonic term without a hidden layer. The trained network in feedforward operation is fast running, compact, and traceable to the rule base.

    The technique of capture reaction studies of giant resonance properties is described, and a number of examples are given. Most of the recent work of interest has been in proton capture, in part because of the great utility (and availability) of polarized beams; most of the discussion concerns this reaction. Alpha capture, which has been a useful tool for exploring isoscalar E2 strength, and neutron capture are, however, also treated. 46 references, 14 figures

    The ability to capture hypervelocity projectiles intact opens a new technique available for hypervelocity research. A determination of the reactions taking place between the projectile and the capture medium during the process of intact capture is extremely important to an understanding of the intact capture phenomenon, to improving the capture technique, and to developing a theory describing the phenomenon. The intact capture of hypervelocity projectiles by underdense media generates spectra, characteristic of the material species of projectile and capture medium involved. Initial exploratory results into real-time characterization of hypervelocity intact capture techniques by spectroscopy include ultra-violet and visible spectra obtained by use of reflecting gratings, transmitting gratings, and prisms, and recorded by photographic and electronic means. Spectrometry proved to be a valuable real-time diagnostic tool for hypervelocity intact capture events, offering understanding of the interactions of the projectile and the capture medium during the initial period and providing information not obtainable by other characterizations. Preliminary results and analyses of spectra produced by the intact capture of hypervelocity aluminum spheres in polyethylene (PE), polystyrene (PS), and polyurethane (PU) foams are presented. Included are tentative emission species identifications, as well as gray body temperatures produced in the intact capture process.

    Full Text Available In the context of recent arbovirus epidemics, questions about the frequency of simultaneous infection of patients with different arbovirus species have been raised. In 2014, a major Chikungunya virus (CHIKV epidemic impacted the Caribbean and South America. As part of ongoing screening of schoolchildren presenting with acute undifferentiated febrile illness in rural Haiti, we used RT-PCR to identify CHIKV infections in 82 of 100 children with this diagnosis during May-August 2014. Among these, eight were infected with a second arbovirus: six with Zika virus (ZIKV, one with Dengue virus serotype 2, and one with Mayaro virus (MAYV. These dual infections were only detected following culture of the specimen, suggesting low viral loads of the co-infecting species. Phylogenetic analyses indicated that the ZIKV and MAYV strains differ from those detected later in 2014 and 2015, respectively. Moreover, CHIKV and ZIKV strains from co-infected patients clustered monophyletically in their respective phylogeny, and clock calibration traced back the common ancestor of each clade to an overlapping timeframe of introduction of these arboviruses onto the island.

    Diarrhea in patients with acquired immunodeficiency syndrome (AIDS) may cause malabsorption of medications and failure of antiretroviral therapy (ART). We prospectively evaluated human immunodeficiency virus-1 (HIV-1)-infected patients with and without chronic diarrhea initiating ART in Haiti. We report mean plasma antiretroviral concentrations at 2 and 4 weeks. We measured plasma HIV-1 RNA levels at four points. Fifty-two HIV-1-infected patients (26 matched pairs) were enrolled. No differences in antiretroviral concentrations were detected. At week 24, 18/25 (72%) cases and 16/24 (68%) controls had undetectable plasma HIV-1 RNA levels (P = 0.69). Patients with plasma HIV-1 RNA levels > 50 copies/mL at week 24 had lower early efavirenz concentrations than patients with undetectable HIV-1 RNA (2,621 ng/mL versus 5,278 ng/mL; P = 0.02). Diarrhea at ART initiation does not influence plasma concentrations of the medications evaluated. Virologic outcome at Week 24 does correlate with efavirenz concentrations early in therapy but not with the presence of chronic diarrhea. PMID:21633022

    As part of on-going arboviral surveillance activity in a semi-rural region in Haiti, Chikungunya virus (CHIKV)-positive mosquito pools were identified in 2014 (the peak of the Caribbean Asian-clade epidemic), and again in 2016 by RT-PCR. In 2014, CHIKV was only identified in Aedes aegypti (11 positive pools/124 screened). In contrast, in sampling in 2016, CHIKV was not identified in Ae. aegypti, but, rather, in (a) a female Aedes albopictus pool, and (b) a female Culex quinquefasciatus pool. Genomic sequence analyses indicated that the CHIKV viruses in the 2016 mosquito pools were from the East-Central-South African (ECSA) lineage, rather than the Asian lineage. In phylogenetic studies, these ECSA lineage strains form a new ECSA subgroup (subgroup IIa) together with Brazilian ECSA lineage strains from an isolated human outbreak in 2014, and a mosquito pool in 2016. Additional analyses date the most recent common ancestor of the ECSA IIa subgroup around May 2007, and the 2016 Haitian CHIKV genomes around December 2015. Known CHIKV mutations associated with improved Ae. albopictus vector competence were not identified. Isolation of this newly identified lineage from Ae. albopictus is of concern, as this vector has a broader geographic range than Ae. aegypti, especially in temperate areas of North America, and stresses the importance for continued vector surveillance.

  11. Influence of transportation cost on long-term retention in clinic for HIV patients in rural Haiti.

    With improved access to antiretroviral therapy in resource-constrained settings, long-term retention in HIV clinics has become an important means of reducing costs and improving outcomes. Published data on retention in HIV clinics beyond 24 months are, however, limited. In our clinic in rural Haiti, we hypothesized that individuals residing in locations with higher transportation costs to clinic would have poorer retention than those who had lower costs. We used a retrospective cohort design to evaluate potential predictors of HIV clinic retention. Patient information was abstracted from the electronic medical records. Cox proportional hazards regression was used to identify independent predictors of 4-year clinic retention. There were 410 patients in our cohort, 266 (64.9%) females and 144 (35.1%) males. Forty-five (11%) patients lived in locations with transportation costs >$2. Males were 1.5 times more likely to live in municipalities with transportation costs to clinic of >$2. Multivariate analysis suggested that age transportation cost were independent predictors of loss to follow-up (LTFU): risk ratio of 2.98, 95% confidence interval (CI): 1.73 to 4.96, P transportation costs greater than $2 were 1.9 times more likely to be lost to care compared with those who paid less for transportation. HIV treatment programs in resource-constrained settings may need to pay closer attention to issues related to transportation cost to improve patient retention.

  12. Optimizing Household Chlorination Marketing Strategies: A Randomized Controlled Trial on the Effect of Price and Promotion on Adoption in Haiti.

    Household water treatment can reduce diarrheal morbidity and mortality in developing countries, but adoption remains low and supply is often unreliable. To test effects of marketing strategies on consumers and suppliers, we randomized 1,798 households in rural Haiti and collected data on purchases of a household chlorination product for 4 months. Households received randomly selected prices ($0.11-$0.56 per chlorine bottle), and half received monthly visits from sales agents. Each $0.22 drop in price increased purchases by 0.10 bottles per household per month ( P sales agents increased purchases at mid-range prices; however, the additional revenue did not offset visit cost. Choosing the lowest price and conducting visits maximizes chlorine purchase, whereas slightly raising the retail price and not conducting visits maximizes cost recovery. For the equivalent cost, price discounts increase purchases 4.2 times as much as adding visits at the current retail price. In this context, price subsidies may be a more cost-effective use of resources than household visits, though all marketing strategies tested offer cost-effective ways to achieve incremental health impact. Decisions about pricing and promotion for health products in developing countries affect health impact, cost recovery, and cost-effectiveness, and tradeoffs between these goals should be made explicit in program design.

    This paper details the steps to design and implement a positive deviance-informed, "Hearth" approach for the nutritional rehabilitation of malnourished children in the district of Leogane, Haiti. Groups of four to five children met daily for two weeks at the home of a local volunteer mother for nutritional and health messages and a well-balanced meal. Health messages and meal components were determined using information gathered from interviews with the mothers of positive deviant children in the community who are well nourished despite their family's limited economic resources. Hearth participants were then followed for six months in their own home by the program "monitrices," women hired from each village and intensively trained to supervise the Hearth program, periodically weigh the children to evaluate their progress, and liaise between the hospital and the community. Monitoring from the first cycle indicated that 100% of children in eight villages and 66% of children in the remaining five villages continued to gain weight as fast or faster than the international standard median six months after participating in a Hearth program. At the conclusion of this cycle, programmers interviewed participant and non-participant families and made six modifications to the model, including the addition of a microcredit option for participating mothers.

    2008-12-01

    Full Text Available Examines how sexual and gender values in rural Haiti are expressed through 'téat', theatrical, songs and performances among girls from 10 to 20 years. Author describes how these sexual values relate to a concept of gendered capital, or what he calls a "sexual-moral economy", whereby men who want sex with women need to provide material rewards for this sexual access. He explains how this combines with certain gender socializations and views of men, unlike women, really needing sex, and socialized toward this, also by women, and thus from an early age to aggressively pursue women, and women on the other hand toward restraint, and to require material rewards. Author illustrates, through examples, how téat songs reflect and refer to these values, often through sexual metaphors. In addition, he shows how they relate to the wider social and gender context of matrifocality and subsistence strategies, notably the household, wherein women tend to be dominant over men, who supplied the house as expected price for her sex, manages production and reproduction of her daughters in it, instilling them also with the said sexual values, and with children seen as necessary for household work, as the women also engage in market activities outside of the house.

    Full Text Available Ionospheric perturbations in possible association with the 2010 Haiti earthquake occurred on 12 January 2010 (with a magnitude of 7.0 and depth of 10 km are investigated on the basis of subionospheric propagation data from the NAA transmitter on the east coast of the USA to a VLF receiving station in Peru. The local nighttime VLF amplitude data are extensively investigated during the period from the beginning of October 2009 to the end of March 2010, in which the trend (nighttime average amplitude, dispersion and nighttime fluctuation are analysed. It is found that a clear precursory ionosphere perturbation is detected just around New Years day of 2010, about 12 days before the main shock, which is characterised by the simultaneous decrease in the trend and the increases in dispersion and nighttime fluctuation. An additional finding might be the presence of the effect of the Earth's tide one and two months before the main shock, which can only be seen for a huge EQ.

    Purpose The nonprofit Project Medishare launched a breast cancer treatment program in Port-au-Prince in July 2013 to address the demand for breast cancer care in Haiti. We outline the development of the program, highlight specific challenges, and discuss key considerations for others working in global oncology. Methods We reflected on our experiences in the key areas of developing partnerships, building laboratory capacity, conducting medical training, using treatment algorithms, and ensuring access to safe, low-cost chemotherapy drugs. We also critically reviewed our costs and quality measures. Results The program has treated a total of 139 patients with breast cancer with strong adherence to treatment regimens in 85% of patients. In 273 chemotherapy administrations, no serious exposure or adverse safety events were reported by staff. The mortality rate for 94 patients for whom we have complete data was 24% with a median survival time of 53 months. Our outcome data were likely influenced by stage at presentation, with more than half of patients presenting more than 12 months after first noticing a tumor. Future efforts will therefore focus on continuing to improve the level of care, while working with local partners to spread awareness, increase screening, and get more women into care earlier in the course of their disease. Conclusion Our experiences may inform others working to implement protocol-based cancer treatment programs in resource-poor settings and can provide valuable lessons learned for future global oncology efforts.

    Full Text Available Background. In Haiti, breast cancer patients present at such advanced stages that even modern therapies offer modest survival benefit. Identifying the personal, sociocultural, and economic barriers-to-care delaying patient presentation is crucial to controlling disease. Methods. Patients presenting to the Hôpital Bon Sauveur in Cange were prospectively accrued. Delay was defined as 12 weeks or longer from initial sign/symptom discovery to presentation, as durations greater than this cutoff correlate with reduced survival. A matched case-control analysis with multivariate logistic regression was used to identify factors predicting delay. Results. Of N=123 patients accrued, 90 (73% reported symptom-presentation duration and formed the basis of this study: 52 patients presented within 12 weeks of symptoms, while 38 patients waited longer than 12 weeks. On logistic regression, lower education status (OR = 5.6, P=0.03, failure to initially recognize mass as important (OR = 13.0, P<0.01, and fear of treatment cost (OR = 8.3, P=0.03 were shown to independently predict delayed patient presentation. Conclusion. To reduce stage at presentation, future interventions must educate patients on the recognition of initial breast cancer signs and symptoms and address cost concerns by providing care free of charge and/or advertising that existing care is already free.

    Moringa oleifera is a plant that grows in tropical and subtropical areas of the world. Its leaves are rich of nutrients and bioactive compounds. However, several differences are reported in the literature. In this article we performed a nutritional characterization and a phenolic profiling of M. oleifera leaves grown in Chad, Sahrawi refugee camps, and Haiti. In addition, we investigated the presence of salicylic and ferulic acids, two phenolic acids with pharmacological activity, whose presence in M. oleifera leaves has been scarcely investigated so far. Several differences were observed among the samples. Nevertheless, the leaves were rich in protein, minerals, and β-carotene. Quercetin and kaempferol glycosides were the main phenolic compounds identified in the methanolic extracts. Finally, salicylic and ferulic acids were found in a concentration range of 0.14-0.33 and 6.61-9.69 mg/100 g, respectively. In conclusion, we observed some differences in terms of nutrients and phenolic compounds in M. oleifera leaves grown in different countries. Nevertheless, these leaves are a good and economical source of nutrients for tropical and sub-tropical countries. Furthermore, M. oleifera leaves are a source of flavonoids and phenolic acids, among which salicylic and ferulic acids, and therefore they could be used as nutraceutical and functional ingredients.

    The reconstruction of healthcare systems in developing countries after natural disasters is poorly understood. Using data collected before and after the 2010 Haiti earthquake, we detail the response of aid agencies and their interaction with local healthcare providers in Leogane, the city closest to the epicenter. We find that the period after the earthquake was associated with an increase in the total number of healthcare facilities, inpatient beds, and surgical facilities and that international aid has been a driving force behind this recovery. Aid has funded 12 of 13 new healthcare facilities that have opened since the earthquake as well as the reconstruction of 7 of 8 healthcare facilities that have been rebuilt. Despite increases in free, aid-financed healthcare, private Haitian healthcare facilities have remained at a constant number. The planned phase-out of several aid-financed facilities, however, will leave Leogane with fewer inpatient beds and healthcare services compared with the pre-earthquake period. © The American Society of Tropical Medicine and Hygiene.

    The development of boron-containing compounds which localize selectively in tumor may require a tumor-by-tumor type of approach that exploits any metabolic pathways unique to the particular type of tumor. Melanin-producing melanomas actively transport and metabolize aromatic amino acids for use as precursors in the synthesis of the pigment melanin. It has been shown that the boron-containing amino acid analog p-borono-phenylalanine (BPA) is selectively accumulated in melanoma tissue, producing boron concentrations in tumor that are within the range estimated to be necessary for successful boron neutron capture therapy (BNCT). We report here the results of therapy experiments carried out at the Brookhaven Medical Research Reactor (BMRR). 21 refs., 5 figs., 3 tabs.

    Although other researchers had previously observed the random motion of pollen grains suspended in water through a microscope, Robert Brown's name is associated with this behaviour based on observations he made in 1828. It was not until Einstein's work in the early 1900s however, that the origin of this irregular motion was established to be the result of collisions with molecules which were so small as to be invisible in a light microscope (Einstein A 1965 Investigations on the Theory of the Brownian Movement ed R Furth (New York: Dover) (transl. Cowper A D) (5 papers)). Jean Perrin in 1908 (Perrin J 1923 Atoms (New York: Van Nostrand-Reinhold) (transl. Hammick D)) was able, through a series of painstaking experiments, to establish the validity of Einstein's equation. We describe here the details of a junior level undergraduate physics laboratory experiment where students used a microscope, a video camera and video capture software to verify Einstein's famous calculation of 1905.

    Nowadays, highly-detailed animations of live-actor performances are increasingly easier to acquire and 3D Video has reached considerable attentions in visual media production. In this book, we address the problem of extracting or acquiring and then reusing non-rigid parametrization for video-based animations. At first sight, a crucial challenge is to reproduce plausible boneless deformations while preserving global and local captured properties of dynamic surfaces with a limited number of controllable, flexible and reusable parameters. To solve this challenge, we directly rely on a skin-detached dimension reduction thanks to the well-known cage-based paradigm. First, we achieve Scalable Inverse Cage-based Modeling by transposing the inverse kinematics paradigm on surfaces. Thus, we introduce a cage inversion process with user-specified screen-space constraints. Secondly, we convert non-rigid animated surfaces into a sequence of optimal cage parameters via Cage-based Animation Conversion. Building upon this re...

    Potentially optimal conditions for Neutron Capture Therapy (NCT) may soon be in hand due to the anticipated development of band-pass filtered beams relatively free of fast neutron contaminations, and of broadly applicable biomolecules for boron transport such as porphyrins and monoclonal antibodies. Consequently, a number of groups in the US are now devoting their efforts to exploring NCT for clinical application. The purpose of this Workshop was to bring these groups together to exchange views on significant problems of mutual interest, and to assure a unified and effective approach to the solutions. Several areas of preclinical investigation were deemed to be necessary before it would be possible to initiate clinical studies. As neither the monomer nor the dimer of sulfhydryl boron hydride is unequivocally preferable at this time, studies on both compounds should be continued until one is proven superior.

    In this paper we study the capture of a negative muon by H e 3 in the channel μ-+H e 3 +V. Following Primakoff we use the V-A theory of the weak interactions. We include also first order relativistic terms. To describe the initial and final nuclei we have used the most general wave function allowed by the Paul is exclusion principle, assuming that these nuclei are a mixture of an isospin doublet and quadruplet. For the part of the wave function depending on the inter nucleonic distances, we have taken four different function without hard-core, a gaussian and three kinds of Irving type. We present in several tables the results obtained varying g p /g v and g A /g y as well as the amplitudes of the fourteen terms forming the nuclear wave function. (Author) 35 refs

This is the largest panorama obtained yet by either rover. It was taken in eight segments using six filters per segment, for a total of 558 images and more than 75 megabytes of data. Additional lower elevation tiers were added to ensure that the entire crater was covered in the mosaic. This panorama depicts a story of exploration including the rover's lander, a thorough examination of the outcrop, a study of the soils at the near-side of the lander, a successful exit from Eagle Crater and finally the rover's next desination, the large crater dubbed 'Endurance'.

    Measurements of the Coulomb dissociation of 8 B have been used to infer the rate of the inverse radiative proton capture on 7 Be. The analysis is usually based on the assumptions that the two processes are related by detailed balance and described by E1 transitions. However, there are corrections to this relation. The Coulomb form factors for the two processes, for example, are not identical. There are also E2 transitions and higher-order effects in the Coulomb dissociation, and the nuclear induced breakup cannot always be ignored. While adding first-order E2 transitions enhances the decay energy spectrum, the other mechanisms cause a suppression at low relative energies. The net result may accidentally be close to the conventional first-order E1 calculation, but there are differences which cannot be ignored if accuracies of 10% or better are needed

    Neptune's moon Triton is widely thought to have been captured from heliocentric orbit, most likely through binary dissociation (Agnor and Hamilton, 2006). Triton's original eccentric orbit must have been subsequently circularized by satellite tides (Goldreich et al. 1989). Cuk and Gladman (2005) found that Kozai oscillations make early tidal evolution inefficient, and have proposed that collisions between Triton and debris from pre-existing satellites was the dominant mechanism of shrinking Triton's large post-capture orbit. However, Cuk and Hamilton (DPS 2016), using numerical simulations and results of Stewart and Leinhardt (2012), have found that collisions between regular satellites are unlikely to be destructive, while collisions between prograde moons and Triton are certainly erosive if not catastrophic. An obvious outcome would be pre-existing moon material gradually grinding down Triton and making it reaccrete in the local Laplace plane, in conflict with Triton's large current inclination. We propose that the crucial ingredient for understanding the early evolution of the Neptunian system are the collisions between the moons and the prograde and retrograde debris originating from the pre-existing moons and Triton. In particular, we expect early erosive impact(s) on Triton to generate debris that will, in subsequent collisions, disrupt the regular satellites. If the retrograde material were to dominate at some planetocentric distances, the end result may be a large cloud or disk of retrograde debris that would be accreted by Triton, shrinking Triton's orbit. Some of the prograde debris could survive in a compact disk interior to Triton's pericenter, eventually forming the inner moons of Neptune. We will present results of numerical modeling of these complex dynamical processes at the meeting.

    In the Standard Model, the weak interaction is purely V-A in character. However in semileptonic reactions the strong force induces additional couplings. One of these, the induced pseudoscalar coupling g p , is still very poorly determined experimentally. Using PCAC and the Goldberger-Treiman relation, one can obtain the estimate g p /g a = 6.8 for the nucleon. At present, the world average of 5 measurements of the rate of ordinary muon capture (each with an error in excess of 40%) yields g p /g a = 6.9 ± 1.5. Radiative Muon Capture (RMC) is considerably more sensitive to the pseudoscalar coupling. Due to the extremely small branching ratio (∼ 6 x 10 -8 ), the elementary reaction μ - p→ μnγ has never been measured. Effort to date has concentrated on nuclear RMC where the branching ratio is much larger, but the interpretation of these results is hindered by nuclear structure uncertainties. A measurement is being carried out at TRIUMF to determine the rate of RMC on hydrogen to a precision of 8% leading to a determination of g p with an error of 10%. The detection system is based on a large-volume drift chamber acting as a pair spectrometer. The drift chamber covers a solid angle of about 2π. At a magnetic field of 2.4 kG the acceptance for 70 MeV photons is about 0.9% using a 1.2 mm thick Pb photon converter. The expected photon energy resolution is about 10% FWHM. A detailed discussion of the systematic errors expected in the experiment and the preliminary results on the performance of the detector will be presented

    The Small Particles Intact Capture Experiment (SPICE) will develop technologies and engineering techniques necessary to capture nearly intact, uncontaminated cosmic and interplanetary dust particles (IDP's). Successful capture of such particles will benefit the exobiology and planetary science communities by providing particulate samples that may have survived unaltered since the formation of the solar system. Characterization of these particles may contribute fundamental data to our knowledge of how these particles could have formed into our planet Earth and, perhaps, contributed to the beginnings of life. The term 'uncontaminated' means that captured cosmic and IDP particles are free of organic contamination from the capture process and the term 'nearly intact capture' means that their chemical and elemental components are not materially altered during capture. The key to capturing cosmic and IDP particles that are organic-contamination free and nearly intact is the capture medium. Initial screening of capture media included organic foams, multiple thin foil layers, and aerogel (a silica gel); but, with the exception of aerogel, the requirements of no contamination or nearly intact capture were not met. To ensure no contamination of particles in the capture process, high-purity aerogel was chosen. High-purity aerogel results in high clarity (visual clearness), a useful quality in detection and recovery of embedded captured particles from the aerogel. P. Tsou at the Jet Propulsion Laboratory (JPL) originally described the use of aerogel for this purpose and reported laboratory test results. He has flown aerogel as a 'GAS-can Lid' payload on STS-47 and is evaluating the results. The Timeband Capture Cell Experiment (TICCE), a Eureca 1 experiment, is also flying aerogel and is scheduled for recovery in late April.

    The purpose of this study was to explore the perceptions of violence against women (VAW) held by Haitian men to gain a better understanding of why VAW occurs. Women in Haiti have experienced significant violence, both before and following the 2010 earthquake. Fifteen men aged 26 to 47 participated in a focus group. The data revealed three themes: men's beliefs about VAW and its context, factors influencing VAW, and recommended interventions. When approaching VAW, men must be part of the collective effort. Their insights are valuable when planning and implementing interventions to decrease VAW in Haiti and worldwide.

    The governments of Haiti and the Dominican Republic have a binational agreement to work towards malaria elimination for the island of Hispaniola by the year 2020. Understanding malaria-related knowledge and behaviors can help inform elimination efforts. This study examined the association between social-behavioral factors, like bedtime and bed net ownership, with malaria seroconversion status among people in the Ouest and Sud-Est departments of Haiti. In 2013, cross-sectional survey data (n=377) and blood samples were collected from a convenience sample of individuals within community, clinic and school settings. Logistic regression models were constructed to examine associations between social-behavioral factors and malaria exposure, adjusting for potential confounders. Compared to people going to bed between 6 and 8 pm, those going to bed between 8 and 10 pm were 2.67 (OR, 95% CI: 1.16-6.14) times as likely to have been exposed to malaria. Participants who reported going to bed after 10 pm were 5.96 times as likely to have had previous malaria exposure (OR, 95% CI: 2.26-15.7), compared to 6-8 pm. No significant associations were found between malaria exposure and either insecticide use nor bed net ownership. These findings are consistent with suspected feeding behaviors of Anopheles albimanus, which prefers feeding at night and outdoors. Study findings may improve overall understanding of malaria transmission in Haiti and potentially guide future studies conducted in this region. Copyright © 2017 Elsevier B.V. All rights reserved.

    Although prehospital care is recognized as key in health systems development, it has been largely neglected in Haiti. The North East Department is one of the poorest areas of Haiti, and is a region where no data on out-of-hospital health care exists. This research assessed prehospital characteristics in the North East Department with the aim of providing baseline data to inform prehospital systems development. In this observational study, data were collected from patients presenting at the Fort Liberté Hospital, the public regional referral health center in the North East Department. Data were accrued from April 2, 2012 through June 5, 2012. All patients accessing acute care at the hospital were eligible for enrollment. After obtaining consent, data on demographics, health needs, and prehospital information were gathered via a standardized questionnaire administered by hospital staff trained in study protocols. Data were collected from 441 patient visits. The median age was 24 years, with 62% of the population being female. Medical complaints comprised 75% of visits, with fever and gastrointestinal complaints being the most common reasons for presentation. Traumatic injuries accounted for 25% of encounters, with an equal distribution of blunt and penetrating events. Extremity injuries were the most common traumatic subclassification. The majority of patients (67.2%) were transported by motorcycle taxi and paid transport fees. Trauma patients were more likely to be transported without charge (OR = 9.10; 95% CI, 2.19-37.76; P Haiti. Out-of-hospital care is nearly nonexistent in the region and its development has the potential to yield public health benefits.

    Full text of publication follows. Objectives: we investigated the role of internalizing/non-internalizing monoclonal antibodies (mAbs) on the final outcome (efficacy/toxicity) of mice treated with alpha radioimmunotherapy (α- RIT) using 212 Pb-labeled mAbs. The relationship between distribution of radioactivity at the tissue level and biological parameters was also assessed. Methods: nude mice bearing 2-3 mm peritoneal nodules obtained by xenograft of A-431 tumor cells, expressing low and high level of HER2 and CEA receptors, respectively, were intraperitoneally (i.p.) injected with increasing activities (370-1480 kBq; 37 MBq/mg) of either 35A7 (non-internalising anti-CEA), Trastuzumab (internalizing anti-HER2) or PX (non-specific) 212 Pb-labeled mAbs. Control groups were injected with corresponding amount of unlabeled mAbs or with NaCl. Tumor growth was followed by bioluminescence and median survival (MS) of control and treated mice was determined. 212 Pb-35A7 and 212 Pb-Trastuzumab biodistribution was used to determine the cumulative uptake of radioactivity (UOR) in organs and tumors. Mean absorbed doses were calculated using the MIRD formalism. Haematological, liver and kidney toxicities were also assessed. Distribution of radioactivity at the tissue level was determined by digital micro-autoradiography and the relationship with biological markers of tissue damage was investigated using immunohistochemistry. Results: a mild and transient haematological toxicity in groups treated with the highest amount of activity was observed. MS of the groups treated either with internalizing or non-internalizing 212 Pb-labeled mAbs was significantly improved compared to those treated with non-specific 212 Pb-PX or those only given unlabeled mAbs or just NaCl. MS ranged from 42 days to 94 days using various activity levels of anti-CEA 212 Pb-35A7 while MS was not reached over the follow-up period of 130 days for mice treated with anti-HER2 212 Pb-Trastuzumab. However, UOR and

    The author first highlights the reasons why storing carbon dioxide in geological formations could be a solution in the struggle against global warming and climate change. Thus, he comments various evolutions and prospective data about carbon emissions or fossil energy consumption as well as various studies performed by international bodies and agencies which show the interest of carbon dioxide storage. He comments the evolution of CO 2 contributions of different industrial sectors and activities, notably in France. He presents the different storage modes and methods which concern different geological formations (saline aquifers, abandoned oil or gas fields, not exploitable coal seams) and different processes (sorption, carbonation). He discusses the risks associated with these storages, the storable quantities, evokes some existing installations in different countries. He comments different ways to capture carbon dioxide (in post-combustion, through oxy-combustion, by pre-combustion) and briefly evokes some existing installations. He evokes the issue of transport, and discusses efficiency and cost aspects, and finally has few words on legal aspects and social acceptability

    The concentration of carbon dioxide, one of the most important representatives of greenhouse gases in the atmosphere continues to rise. Fossil fuels burned in thermal power plants currently represent 80% of total energy production around the world and are the largest point sources of CO 2 , accounting for approximately 40% of total CO 2 emissions. There are several options for reducing CO 2 emissions: reducing demand, improving production efficiency and carbon capture and storage (CCS, carbon capture and storage). Capture and storage of carbon dioxide is generally a three-step process: 1 st Capture and compression of combustion products, 2 nd transport (mostly pipeline) and 3 rd utilization (eg. production of urea, beverage industry, production of dry ice, etc.). Technologies for CO 2 capturing used in power plants burning fossil fuels can be divided into four groups, each of which requires a completely different approach to CO 2 capture.

    According to models of attention and emotion, threat captures and holds attention. In behavioral tasks, robust evidence has been found for attentional holding but not for attentional capture by threat. An important explanation for the absence of attentional capture effects is that the visual stimuli used posed no genuine threat. The present study investigated whether visual cues that signal an aversive white noise can elicit attentional capture and holding effects. Cues presented in an attentional task were simultaneously provided with a threat value through an aversive conditioning procedure. Response latencies showed that threatening cues captured and held attention. These results support recent views on attention to threat, proposing that imminent threat captures attention in everyone.

    Purpose: To increase the area of contact between the capturing materials for the radioactive corrosion products contained in the coolants and the coolants by producing stirred turbulent flows in the coolant flow channel of LMFBR type reactors. Constitution: Constituent materials for the nuclear fuel elements or the reactor core structures are activated under the neutron irradiation, corroded and transferred into the coolants. While capturing devices made of pure metal nickel are used for the elimination of the corrosion products, since the coolants form laminar flows due to the viscosity thereof near the surface of the capturing materials, the probability that the corrosion products in the coolants flowing through the middle portion of the channel contact the capturing materials is reduced. In this invention, rotating rolls and flow channels in which the balls are rotated are disposed at the upstream of the capturing device to forcively disturb the flow of the liquid sodium, whereby the radioactive corrosion products can effectively be captured.

    Low lamb recruitment is a major challenge facing managers attempting to mitigate the decline of bighorn sheep (Ovis canadensis), and investigations into the underlying mechanisms are limited because of the inability to readily capture and monitor bighorn sheep lambs. We evaluated 4 capture techniques for bighorn sheep lambs: 1) hand-capture of lambs from radiocollared adult females fitted with vaginal implant transmitters (VITs), 2) hand-capture of lambs of intensively monitored radiocollared adult females, 3) helicopter net-gunning, and 4) hand-capture of lambs from helicopters. During 2010–2012, we successfully captured 90% of lambs from females that retained VITs to ≤1 day of parturition, although we noted differences in capture rates between an area of high road density in the Black Hills (92–100%) of South Dakota, USA, and less accessible areas of New Mexico (71%), USA. Retention of VITs was 78% with pre-partum expulsion the main cause of failure. We were less likely to capture lambs from females that expelled VITs ≥1 day of parturition (range = 80–83%) or females that were collared without VITs (range = 60–78%). We used helicopter net-gunning at several sites in 1999, 2001–2002, and 2011, and it proved a useful technique; however, at one site, attempts to capture lambs led to lamb predation by golden eagles (Aquila chrysaetos). We attempted helicopter hand-captures at one site in 1999, and they also were successful in certain circumstances and avoided risk of physical trauma from net-gunning; however, application was limited. In areas of low accessibility or if personnel lack the ability to monitor females and/or VITs for extended periods, helicopter capture may provide a viable option for lamb capture.

    Large-scale deforestation, intensive land use and unfavourable rainfall conditions are responsible for significant continuous degradation of the Haitian uplands. To develop soil conservation strategies, simple and cost-effective methods are needed to assess rates of soil loss from farmland in Haiti. The fallout radionuclide caesium-137 ( 137 Cs) provides one such means of documenting medium-term soil redistribution rates. In this contribution, the authors report the first use in Haiti of 137 Cs measurements to document soil redistribution rates and the associated pattern of erosion/sedimentation rates along typical hillslopes within a traditional upland Haitian farming area. The local 137 Cs reference inventory, measured at an adjacent undisturbed flat area, was 670 Bq m -2 (SD = 100 Bq m -2 , CV = 15%, n = 7). Within the study area, where cultivation commenced in 1992 after deforestation, three representative downslope transects were sampled. These were characterized by 137 Cs inventories ranging from 190 to 2200 Bq m -2 . Although, the study area was cultivated by the local farmers, the 137 Cs depth distributions obtained from the area differed markedly from those expected from a cultivated area. They showed little evidence of tillage mixing within the upper part of the soil or, more particularly, of the near-uniform activities normally associated with the plough layer or cultivation horizon. They were very similar to that found at the reference site and were characterized by high 137 Cs activities at the surface and much lower activities at greater depths. This situation is thought to reflect the traditional manual tillage practices which cause limited disturbance and mixing of the upper part of the soil. It precluded the use of the conversion models normally used to estimate soil redistribution rates from 137 Cs measurements on cultivated soils and the Diffusion and Migration conversion model frequently used for uncultivated soils was modified for

    Attentional capture by abrupt onsets can be modulated by several factors, including the complexity, or perceptual load, of a scene. We have recently demonstrated that observers are less likely to be captured by abruptly appearing, task-irrelevant stimuli when they perform a search that is high, as opposed to low, in perceptual load (Cosman & Vecera, 2009), consistent with perceptual load theory. However, recent results indicate that onset frequency can influence stimulus-driven capture, with infrequent onsets capturing attention more often than did frequent onsets. Importantly, in our previous task, an abrupt onset was present on every trial, and consequently, attentional capture might have been affected by both onset frequency and perceptual load. In the present experiment, we examined whether onset frequency influences attentional capture under conditions of high perceptual load. When onsets were presented frequently, we replicated our earlier results; attentional capture by onsets was modulated under conditions of high perceptual load. Importantly, however, when onsets were presented infrequently, we observed robust capture effects. These results conflict with a strong form of load theory and, instead, suggest that exposure to the elements of a task (e.g., abrupt onsets) combines with high perceptual load to modulate attentional capture by task-irrelevant information.

    Full Text Available Purpose: This study examines the determinants of ex-ante state capture in Poland. Methodology: In order to establish the determinants of ex-ante state capture a logistic regression is estimated. Findings: The study shows that in Poland the majority of legal acts were passed with the aim to satisfy the interest of particular groups. Furthermore, the regression analysis shows that the likelihood of state capture increases during the period of higher economic growth and local elections. The likelihood of state capture, however, declines during presidential elections. The results we attribute to different interests of political parties in the period of local and presidential elections. Finally, we fi nd that the state capture increased over the years in Poland. Additionally, we show that the EU accession did not prevent state capture in Poland. In contrast, the fi nancial crisis of 2007 resulted in a wake-up effect and the likelihood of state capture declined in Poland. Research limitations: In the study we employ proxies for state capture, yet we assume that corruption is a widespread phenomenon in Poland. However, due to its nature corruption is very diffi cult to assess and measure. Originality: The study uses a unique dataset on ex-ante state capture that was identifi ed in the legal acts that have been passed in the period 1990–2011 in Poland.

    The Haitian National Nutrition Policy identifies the promotion of optimal complementary feeding (CF) practices as a priority action to prevent childhood malnutrition. We analysed data from the nationally representative 2005-2006 Haiti Demographic Health Survey using the World Health Organization 2008 infant and young child feeding indicators to describe feeding practices among children aged 6-23 months and thus inform policy and programme planning. Multivariate regression analyses were used to identify the determinants of CF practices and to examine their association with child growth outcomes. Overall, 87.3% of 6-8-month-olds received soft, solid or semi-solid foods in the previous 24 h. Minimum dietary diversity (MDD), minimum meal frequency (MMF) and minimum acceptable diet (MAD) were achieved in 29.2%, 45.3% and 17.1% of children aged 6-23 months, respectively. Non-breastfed children were more likely to achieve MDD than breastfed children of the same age (37.3% vs. 25.8%; P < 0.001). The proportion of children achieving MMF varied significantly by age (P < 0.001). Children with overweight mothers were more likely to achieve MDD, MMF and MAD [odds ratio (OR) 2.08, P = 0.012; OR 1.81, P = 0.02; and OR 2.4, P = 0.01, respectively] than children of normal weight mothers. Odds of achieving MDD and MMF increased with household wealth. Among mothers with secondary or more education, achieving MDD or MAD was significantly associated with lower mean weight-for-age z-score and height-for-age z-score (P-value <0.05 for infants and young child feeding indicator × maternal education interaction). CF practices were mostly inadequate and contributed to growth faltering among Haitian children 6-23 months old. © 2013 John Wiley & Sons Ltd.

    Full Text Available Seven rounds of mass drug administration (MDA have been administered in Leogane, Haiti, an area hyperendemic for lymphatic filariasis (LF. Sentinel site surveys showed that the prevalence of microfilaremia was reduced to <1% from levels as high as 15.5%, suggesting that transmission had been reduced. A separate 30-cluster survey of 2- to 4-year-old children was conducted to determine if MDA interrupted transmission. Antigen and antifilarial antibody prevalence were 14.3% and 19.7%, respectively. Follow-up surveys were done in 6 villages, including those selected for the cluster survey, to assess risk factors related to continued LF transmission and to pinpoint hotspots of transmission. One hundred houses were mapped in each village using GPS-enabled PDAs, and then 30 houses and 10 alternates were chosen for testing. All individuals in selected houses were asked to participate in a short survey about participation in MDA, history of residence in Leogane and general knowledge of LF. Survey teams returned to the houses at night to collect blood for antigen testing, microfilaremia and Bm14 antibody testing and collected mosquitoes from these communities in parallel. Antigen prevalence was highly variable among the 6 villages, with the highest being 38.2% (Dampus and the lowest being 2.9% (Corail Lemaire; overall antigen prevalence was 18.5%. Initial cluster surveys of 2- to 4-year-old children were not related to community antigen prevalence. Nearest neighbor analysis found evidence of clustering of infection suggesting that LF infection was focal in distribution. Antigen prevalence among individuals who were systematically noncompliant with the MDAs, i.e. they had never participated, was significantly higher than among compliant individuals (p<0.05. A logistic regression model found that of the factors examined for association with infection, only noncompliance was significantly associated with infection. Thus, continuing transmission of LF seems

    To assess the possible impact of a future earthquake in the urban area of Port-au-Prince (Haiti), we have implemented a simulation approach for complex ground motions produced by an earthquake. To this end, we have integrated local site effect in the prediction of strong ground motions in Port-au-Prince using the complex transfer functions method, which takes into account amplitude changes as well as phase changes. This technique is particularly suitable for basins where a conventional 1D digital approach proves inadequate, as is the case in Port-au-Prince. To do this, we use the results of the Standard Spectral Ratio (SSR) approach of St Fleur et al. (2016) to estimate the amplitude of the response of the site to a nearby rock site. Then, we determine the phase difference between sites, interpreted as changes in the phase of the signal related to local site conditions, using the signals of the 2010 earthquake aftershocks records. Finally, the accelerogram of the simulated earthquake is obtain using the technique of the inverse Fourier transform. The results of this study showed that the strongest soil motions are expected in neighborhoods of downtown Port-au-Prince and adjacent hills. In addition, this simulation method by complex transfer functions was validated by comparison with recorded actual data. Our simulated response spectra reproduce very well both the amplitude and the shape of the response spectra of recorded earthquakes. This new approach allowed to reproduce the lengthening of the signal that could be generated by surface waves at certain stations in the city of Port-au-Prince. However, two points of vigilance must be considered: (1) a good signal-to-noise ratio is necessary to obtain a robust estimate of the site-reference phase shift (ratio at least equal to 10); (2) unless the amplitude and phase changes are measured on strong motion records, this technique does not take non-linear effects into account.

    Reliable evidence of the frequency and severity of human rights abuses in Haiti after the departure of the elected president in 2004 was scarce. We assessed data from a random survey of households in the greater Port-au-Prince area. Using random Global Positioning System (GPS) coordinate sampling, 1260 households (5720 individuals) were sampled. They were interviewed with a structured questionnaire by trained interviewers about their experiences after the departure of President Jean-Bertrand Aristide. The response rate was 90.7%. Information on demographic characteristics, crime, and human rights violations was obtained. Our findings suggested that 8000 individuals were murdered in the greater Port-au-Prince area during the 22-month period assessed. Almost half of the identified perpetrators were government forces or outside political actors. Sexual assault of women and girls was common, with findings suggesting that 35,000 women were victimised in the area; more than half of all female victims were younger than 18 years. Criminals were the most identified perpetrators, but officers from the Haitian National Police accounted for 13.8% and armed anti-Lavalas groups accounted for 10.6% of identified perpetrators of sexual assault. Kidnappings and extrajudicial detentions, physical assaults, death threats, physical threats, and threats of sexual violence were also common. Our results indicate that crime and systematic abuse of human rights were common in Port-au-Prince. Although criminals were the most identified perpetrators of violations, political actors and UN soldiers were also frequently identified. These findings suggest the need for a systematic response from the newly elected Haitian government, the UN, and social service organisations to address the legal, medical, psychological, and economic consequences of widespread human rights abuses and crime.

    Full Text Available In 2010 and 2011, Haiti was heavily affected by a large cholera outbreak that spread throughout the country. Although national health structure-based cholera surveillance was rapidly initiated, a substantial number of community cases might have been missed, particularly in remote areas. We conducted a community-based survey in a large rural, mountainous area across four districts of the Nord department including areas with good versus poor accessibility by road, and rapid versus delayed response to the outbreak to document the true cholera burden and assess geographic distribution and risk factors for cholera mortality.A two-stage, household-based cluster survey was conducted in 138 clusters of 23 households in four districts of the Nord Department from April 22nd to May 13th 2011. A total of 3,187 households and 16,900 individuals were included in the survey, of whom 2,034 (12.0% reported at least one episode of watery diarrhea since the beginning of the outbreak. The two more remote districts, Borgne and Pilate were most affected with attack rates up to 16.2%, and case fatality rates up to 15.2% as compared to the two more accessible districts. Care seeking was also less frequent in the more remote areas with as low as 61.6% of reported patients seeking care. Living in remote areas was found as a risk factor for mortality together with older age, greater severity of illness and not seeking care.These results highlight important geographical disparities and demonstrate that the epidemic caused the highest burden both in terms of cases and deaths in the most remote areas, where up to 5% of the population may have died during the first months of the epidemic. Adapted strategies are needed to rapidly provide treatment as well as prevention measures in remote communities.

    The association between cholera in pregnancy and negative fetal outcome has been described since the 19(th) century. However, there is limited published literature on the subject. We describe pregnancy outcomes from a specialized multidisciplinary hospital unit at the onset of a large cholera outbreak in Haiti in 2010 and 2011. Pregnant women with cholera were hospitalized in a specialized unit within the MSF hospital compound in Léogâne and treated using standard cholera treatment guidelines but with earlier, more intense fluid replacement. All women had intravenous access established at admission regardless of their hydration status, and all received antibiotic treatment. Data were collected on patient demographics, pregnancy and cholera status, and pregnancy outcome. In this analysis we calculated risk ratios for fetal death and performed logistic regression analysis to control for confounding factors. 263 pregnant women with cholera were hospitalized between December 2010 and July 2011. None died during hospitalization, 226 (86%) were discharged with a preserved pregnancy and 16 (6%) had live fullterm singleton births, of whom 2 died within the first 5 days postpartum. The remaining 21 pregnancies (8%) resulted in intrauterine fetal death. The risk of fetal death was associated with factors reflecting severity of the cholera episode: after adjusting for confounding factors, the strongest risk factor for fetal death was severe maternal dehydration (adjusted risk ratio for severe vs. mild dehydration was 9.4, 95% CI 2.5-35.3, p = 0.005), followed by severe vomiting (adjusted risk ratio 5.1, 95% 1.1-23.8, p = 0.041). This is the largest cohort of pregnant women with cholera described to date. The main risk factor identified for fetal death was severity of dehydration. Our experience suggests that establishing specialized multidisciplinary units which facilitate close follow-up of both pregnancy and dehydration status due to cholera could be beneficial

    Disaster medicine research generally lacks control groups. This study aims to describe categories of diagnoses encountered by the Belgian First Aid and Support Team after the 2010 Haiti earthquake and extract earthquake-related changes from comparison with comparable baseline data. The hypothesis is that besides earthquake-related trauma, medical problems emerge soon, questioning an appropriate composition of Foreign Medical Teams and Interagency Emergency Health Kits. Using a descriptive cohort study design, diagnoses of patients presenting to the Belgian field hospital were prospectively registered during 4 weeks after the earthquake and compared with those recorded similarly by Médecins Sans Frontières in the same area and time span in previous and later years. Of 7000 triaged postearthquake patients, 3500 were admitted, of whom 2795 were included and analysed. In the fortnight after the earthquake, 90% suffered from injury. In the following fortnight, medical diseases emerged, particularly respiratory (23%) and digestive (14%). More than 53% developed infections within 3 weeks after the event. Médecins Sans Frontières registered 6407 patients in 2009; 6033 in 2011; and 7300 in 2012. A comparison indicates that postearthquake patients suffered significantly less from violence, but more from wounds, respiratory, digestive and ophthalmological diseases. This is the first comparison of postearthquake diagnoses with baseline data. Within 2 weeks after the acute phase of an earthquake, respiratory, digestive and ophthalmological problems will emerge to the prejudice of trauma. This fact should be anticipated when composing Foreign Medical Teams and Interagency Emergency Health Kits to be sent to the disaster site.

  15. Secondary mapping of lymphatic filariasis in Haiti-definition of transmission foci in low-prevalence settings.

    Directory of Open Access Journals (Sweden)

    Naomi Drexler

    Full Text Available To eliminate Lymphatic filariasis (LF as a public health problem, the World Health Organization (WHO recommends that any area with infection prevalence greater than or equal to 1% (denoted by presence of microfilaremia or antigenemia should receive mass drug administration (MDA of antifilarial drugs for at least five consecutive rounds. Areas of low-antigen prevalence (< 1% are thought to pose little risk for continued transmission of LF. Five low-antigen prevalence communes in Haiti, characterized as part of a national survey, were further assessed for transmission in this study. An initial evaluation of schoolchildren was performed in each commune to identify antigen-positive children who served as index cases for subsequent community surveys conducted among households neighboring the index cases. Global positioning system (GPS coordinates and immunochromatographic tests (ICT for filarial antigenemia were collected on approximately 1,600 persons of all ages in the five communes. The relationship between antigen-positive cases in the community and distance from index cases was evaluated using multivariate regression techniques and analyses of spatial clustering. Community surveys demonstrated higher antigen prevalence in three of the five communes than was observed in the original mapping survey; autochthonous cases were found in the same three communes. Regression techniques identified a significantly increased likelihood of being antigen-positive when living within 20 meters of index cases when controlling for age, gender, and commune. Spatial clustering of antigen-positive cases was observed in some, but not all communes. Our results suggest that localized transmission was present even in low-prevalence settings and suggest that better surveillance methods may be needed to detect microfoci of LF transmission.

    This study examined the demographic and epidemiological differences between patient populations presenting to a rural and an urban clinic in Haiti. A primary health clinic was established in urban Leogane, and a once-weekly clinic was established in Magandou, a rural village. Patient data were recorded for all individuals presenting to each clinic. Over 7 months, 6632 patients (median age 25) were seen in the urban clinic, and 567 (median age 47) in the rural clinic. There was a female majority at both sites. Hypertension was diagnosed in 41.9% (238/567) of the rural population over 40 years of age, while 29.5% (1956/6632) of patients in the urban setting had the same diagnosis (pHaiti must address the wide rural prevalence. STDs are a major urban health issue requiring treatment for both patients and their partners. Vector-borne disease was unseen in the rural clinic, despite an altitude insufficient to prevent mosquito-borne illness. © The Author 2014.

    Although men have substantial decision-making power regarding condom use, the majority of HIV knowledge and prevention studies in the general Haitian population have been conducted among youth and women. We investigated attitudes toward intimate partner violence, knowledge of, and use of condoms among 9493 men in Haiti using data from the 2012 nationally representative Demographic and Health Survey. Only 36% of HIV-negative and 44% of HIV-positive men reported using a condom the last time they had had sex. Logistic regression revealed that believing it was justified for a man to hit or beat his wife if she refuses to have sex with him was associated with a lower odds of condom use. The odds of using a condom during last sex was higher among men who reported knowing condoms can prevent HIV and who had been tested for HIV. Given the low rate of condom use among men in Haiti, these findings suggest that interventions promoting HIV knowledge, HIV testing, and gender-violence prevention among men may also increase condom use. © The Author(s) 2014.

    The left-lateral Enriquillo-Plantain Garden Fault (EPGF) is one of two transform systems that define the Northern Caribbean plate boundary zone. Relative motion across its trace ( 10 mm/yr) evolves from nearly pure strike-slip in western Haiti to transpressional in eastern Haiti, where the fault system may terminate against a south-dipping oblique reverse fault. Lake Azuei is a large (10 km x 25 km) and shallow (turbidity currents. The fact that young turbidites pinch out in upward curves suggests that the folds are actively growing, and that active contractional structures (folds and/or blind thrust faults) control much of the periphery of the lake. A few sediment cores were strategically located where beds are pinching out in order to maximize stratigraphic records. Two of these cores successfully penetrated strata imaged by the CHIRP profiles. On-going Pb210 dating of sediment samples from the cores should constrain sedimentation rates and thus help quantify the rates of the tectonic deformation.

    Full Text Available Abstract Background Few data are available to guide programmatic solutions to the overlapping problems of undernutrition and HIV infection. We evaluated the impact of food assistance on patient outcomes in a comprehensive HIV program in central Haiti in a prospective observational cohort study. Methods Adults with HIV infection were eligible for monthly food rations if they had any one of: tuberculosis, body mass index (BMI 2, CD4 cell count 3 (in the prior 3 months or severe socio-economic conditions. A total of 600 individuals (300 eligible and 300 ineligible for food assistance were interviewed before rations were distributed, at 6 months and at 12 months. Data collected included demographics, BMI and food insecurity score (range 0 - 20. Results At 6- and 12-month time-points, 488 and 340 subjects were eligible for analysis. Multivariable analysis demonstrated that at 6 months, food security significantly improved in those who received food assistance versus who did not (-3.55 vs -0.16; P Conclusions Food assistance was associated with improved food security, increased BMI, and improved adherence to clinic visits at 6 and 12 months among people living with HIV in Haiti and should be part of routine care where HIV and food insecurity overlap.

    2010-06-01

    Full Text Available The potential contribution of remote sensing and GIS techniques to earthquake hazard analysis was investigated in SW-Haiti in order to improve the systematic, standardized inventory of those areas that are more susceptible to earthquake ground motions or to earthquake related secondary effects such as landslides, liquefaction, soil amplifications, compaction or even tsunami-waves. Geophysical, topographical, geological data and satellite images were collected, processed, and integrated into a spatial database using Geoinformation Systems (GIS and image processing techniques. The GIS integrated evaluation of satellite imageries, of digital topographic data and of various open-source geodata can contribute to the acquisition of those specific tectonic, geomorphologic/topographic settings influencing local site conditions in Haiti and, thus, to a first data base stock. Using the weighted overlay techniques in GIS susceptibility maps were produced indicating areas where causal factors influencing surface-near earthquake shock occur aggregated and interfering each other and, thus, rise the susceptibility to soil amplification. This approach was used as well to create landslide and flooding susceptibility maps.

  9. Confusion noise from LISA capture sources

    2004-01-01

    Captures of compact objects (COs) by massive black holes (MBHs) in galactic nuclei will be an important source for LISA, the proposed space-based gravitational wave (GW) detector. However, a large fraction of captures will not be individually resolvable - either because they are too distant, have unfavorable orientation, or have too many years to go before final plunge - and so will constitute a source of 'confusion noise', obscuring other types of sources. In this paper we estimate the shape and overall magnitude of the GW background energy spectrum generated by CO captures. This energy spectrum immediately translates to a spectral density S h capt (f) for the amplitude of capture-generated GWs registered by LISA. The overall magnitude of S h capt (f) is linear in the CO capture rates, which are rather uncertain; therefore we present results for a plausible range of rates. S h capt (f) includes the contributions from both resolvable and unresolvable captures, and thus represents an upper limit on the confusion noise level. We then estimate what fraction of S h capt (f) is due to unresolvable sources and hence constitutes confusion noise. We find that almost all of the contribution to S h capt (f) coming from white dwarf and neutron star captures, and at least ∼30% of the contribution from black hole captures, is from sources that cannot be individually resolved. Nevertheless, we show that the impact of capture confusion noise on the total LISA noise curve ranges from insignificant to modest, depending on the rates. Capture rates at the high end of estimated ranges would raise LISA's overall (effective) noise level [fS h eff (f)] 1/2 by at most a factor ∼2 in the frequency range 1-10 mHz, where LISA is most sensitive. While this slightly elevated noise level would somewhat decrease LISA's sensitivity to other classes of sources, we argue that, overall, this would be a pleasant problem for LISA to have: It would also imply that detection rates for CO captures

  10. Capture of Planetesimals into a Circumterrestrial Swarm

    Weidenschilling, S. J.

    1985-01-01

    The lunar origin model considered in this report involves processing of protolunar material through a circumterrestrial swarm of particles. Once such a swarm has formed, it can gain mass by capturing infalling planetesimals and ejecta from giant impacts on the Earth, although the angular momentum supply from these sources remains a problem. The first stage of formation of a geocentric swarm by capture of planetesimals from initially heliocentric orbits is examined. The only plausible capture mechanism that is not dependent on very low approach velocities is the mutual collision of planetesimals passing within Earth's sphere of influence. The dissipation of energy in inelastic collisions or accretion events changes the value of the Jacobi parameter, allowing capture into bound geocentric orbits. This capture scenario was tested directly by many body numerical integration of planetesimal orbits in near Earth space.

    Accurate neutron-capture cross sections on unstable nuclei near the line of beta stability are crucial for understanding the s-process nucleosynthesis. However, neutron-capture cross sections for short-lived radionuclides are difficult to measure due to the fact that the measurements require both highly radioactive samples and intense neutron sources. Essential ingredients for describing the γ decays following neutron capture are the γ-ray strength function and level densities. We will compare different indirect approaches for obtaining the most relevant observables that can constrain Hauser-Feshbach statistical-model calculations of capture cross sections. Specifically, we will consider photon scattering using monoenergetic and 100% linearly polarized photon beams. Challenges that exist on the path to obtaining neutron-capture cross sections for reactions on isotopes near and far from stability will be discussed.

  13. Capture of irregular satellites at Jupiter

    2014-01-01

    The irregular satellites of outer planets are thought to have been captured from heliocentric orbits. The exact nature of the capture process, however, remains uncertain. We examine the possibility that irregular satellites were captured from the planetesimal disk during the early solar system instability when encounters between the outer planets occurred. Nesvorný et al. already showed that the irregular satellites of Saturn, Uranus, and Neptune were plausibly captured during planetary encounters. Here we find that the current instability models present favorable conditions for capture of irregular satellites at Jupiter as well, mainly because Jupiter undergoes a phase of close encounters with an ice giant. We show that the orbital distribution of bodies captured during planetary encounters provides a good match to the observed distribution of irregular satellites at Jupiter. The capture efficiency for each particle in the original transplanetary disk is found to be (1.3-3.6) × 10 –8 . This is roughly enough to explain the observed population of jovian irregular moons. We also confirm Nesvorný et al.'s results for the irregular satellites of Saturn, Uranus, and Neptune.

    Considerable experimental data have been accumulated relative to the emission of photons accompanying electron capture by swift, highly stripped atoms penetrating crystalline matter under channeling conditions. Recent data suggest that the photon energies may be less than that expected from simple considerations of transitions from the valence band of the solid to hydrogenic states on the moving ion. We have studied theoretically the impact parameter dependence of the radiative electron capture (REC) process, the effect of the ion's wake and the effect of capture from inner shells of the solid on the photon emission probability, using a statistical approach. Numerical comparisons of our results with experiment are made. 13 refs., 6 figs

    In resource-limited settings, efficiency is crucial to maximise resources available for patient care. Time driven activity-based costing (TDABC) estimates costs directly from clinical and administrative processes used in patient care, thereby providing valuable information for process improvements. TDABC is more accurate and simpler than traditional activity-based costing because it assigns resource costs to patients based on the amount of time clinical and staff resources are used in patient encounters. Other costing approaches use somewhat arbitrary allocations that provide little transparency into the actual clinical processes used to treat medical conditions. TDABC has been successfully applied in European and US health-care settings to facilitate process improvements and new reimbursement approaches, but it has not been used in resource-limited settings. We aimed to optimise TDABC for use in a resource-limited setting to provide accurate procedure and service costs, reliably predict financing needs, inform quality improvement initiatives, and maximise efficiency. A multidisciplinary team used TDABC to map clinical processes for obstetric care (vaginal and caesarean deliveries, from triage to post-partum discharge) and breast cancer care (diagnosis, chemotherapy, surgery, and support services, such as pharmacy, radiology, laboratory, and counselling) at Hôpital Universitaire de Mirebalais (HUM) in Haiti. The team estimated the direct costs of personnel, equipment, and facilities used in patient care based on the amount of time each of these resources was used. We calculated inpatient personnel costs by allocating provider costs per staffed bed, and assigned indirect costs (administration, facility maintenance and operations, education, procurement and warehouse, bloodbank, and morgue) to various subgroups of the patient population. This study was approved by the Partners in Health/Zanmi Lasante Research Committee. The direct cost of an uncomplicated vaginal
