The National Aeronautics and Space Administration (NASA) Engineering and Safety Center (NESC) designed, developed and flew the alternative Max Launch Abort System (MLAS) as risk mitigation for the baseline Orion spacecraft launch abort system (LAS) already in development. The NESC was tasked with both formulating a conceptual objective system (OS) design of this alternative MLAS as well as demonstrating this concept with a simulated pad abort flight test. The goal was to obtain sufficient flight test data to assess performance, validate models/tools, and to reduce the design and development risks for a MLAS OS. Less than 2 years after Project start the MLAS simulated pad abort flight test was successfully conducted from Wallops Island on July 8, 2009. The entire flight test duration was 88 seconds during which time multiple staging events were performed and nine separate critically timed parachute deployments occurred as scheduled. Overall, the as-flown flight performance was as predicted prior to launch. This paper provides an overview of the guidance navigation and control (GN&C) technical approaches employed on this rapid prototyping activity. This paper describes the methodology used to design the MLAS flight test vehicle (FTV). Lessons that were learned during this rapid prototyping project are also summarized.

Shreves, Christopher M.

2011-01-01

The Landing Parachute Demonstrator (LPD) was conceived as a low-cost, rapidly-developed means of providing soft landing for the Max Launch Abort System (MLAS) crew module (CM). Its experimental main parachute cluster deployment technique and off-the-shelf hardware necessitated a full-scale drop test prior to the MLAS mission in order to reduce overall mission risk. This test was successfully conducted at Wallops Flight Facility on March 6, 2009, with all vehicle and parachute systems functioning as planned. The results of the drop test successfully qualified the LPD system for the MLAS flight test. This document captures the design, concept of operations and results of the drop test.

NASA has tested the Max Launch Abort System (MLAS) as a risk-mitigation design should problems arise with the baseline Orion spacecraft launch abort design. The Max in MLAS is not Maximum, but rather dedicated to Max Faget, The renowned NASA Spacecraft designer. In the fall of 2009, the mission was flown, with great success, from the NASA Wallops Flight Facility. The MLAS flight test vehicle prototype consists of a boost ring, coast ring, and the MLAS fairing itself, which houses an Orion Command Module (CM) boilerplate. The objective of the MLAS flight test is to reorient the fairing with the CM, weighing approximately 29,000 lbs and traveling 290 fps, 180 degrees to an orientation suitable for the release of the CM during a pad abort and low altitude abort. Although multiple parachute deployments are used in the MLAS flight test vehicle to complete its objective, there are only two parachute types employed in the flight test. Five of the nine parachutes used for MLAS are 27.6 ft DO ribbon parachutes, and the remaining four are standard G-12 cargo parachutes. This paper presents an overview of the 27.6 ft DO ribbon parachute system employed on the MLAS flight test vehicle for coast ring separation, fairing reorientation, and as drogue parachutes for the CM after separation from the fairing. Discussion will include: the process used to select this design, previously proven as a spin/stall recovery parachute; descriptions of all components of the parachute system; the minor modifications necessary to adapt the parachute to the MLAS program; the techniques used to analyze the parachute for the multiple roles it performs; a discussion of the rigging techniques used to interface the parachute system to the vehicle; a brief description of how the evolution of the program affected parachute usage and analysis; and a summary of the results of the flight test, including video of the flight test and subsequent summary analysis. . A discussion of the flight test which was highly successful as well as the flight test observations will be a significant portion of the review.

In 2007, the NASA Exploration Systems Mission Directorate (ESMD) chartered the NASA Engineering Safety Center (NESC) to demonstrate an alternate launch abort concept as risk mitigation for the Orion project's baseline "tower" design. On July 8, 2009, a full scale and passively, aerodynamically stabilized MLAS launch abort demonstrator was successfully launched from Wallops Flight Facility following nearly two years of development work on the launch abort concept: from a napkin sketch to a flight demonstration of the full-scale flight test vehicle. The MLAS flight test vehicle was instrumented with a suite of aerodynamic sensors. The purpose was to obtain sufficient data to demonstrate that the vehicle demonstrated the behavior predicted by Computational Fluid Dynamics (CFD) analysis and wind tunnel testing. This paper describes development of the Air Data Boom (ADB) component of the aerodynamic sensor suite.

The NASA Engineering and Safety Center (NESC) is developing the Max Launch Abort System (MLAS) as a risk-mitigation design should problems arise with the baseline Orion spacecraft launch abort design. The Max in MLAS is dedicated to Max Faget, the renowned NASA spacecraft designer. The MLAS flight test vehicle consists of boost skirt, coast skirt and the MLAS fairing which houses a full scale boilerplate Orion Crew Module (CM). The objective of the flight test is to prove that the CM can be released from the MLAS fairing during pad abort conditions without detrimental recontact between the CM and fairing, achieving performance similar to the Orion launch abort system. The boost and coast skirts provide the necessary thrust and stability to achieve the flight test conditions and are released prior to the test -- much like the Little Joe booster was used in the Apollo Launch Escape System tests. To achieve the test objective, two parachutes are deployed from the fairing to reorient the CM/fairing to a heatshield first orientation. The parachutes then provide the force necessary to reduce the total angle of attack and body angular rates required for safe release of the CM from the fairing. A secondary test objective after CM release from the fairing is to investigate the removal of the CM forward bay cover (FBC) with CM drogue parachutes for the purpose of attempting to synchronously deploying a set of CM main parachutes. Although multiple parachute deployments are used in the MLAS flight test vehicle to complete its objective, there are only two parachute types employed in the flight test. Five of the nine parachutes used for MLAS are 27.6 ft D(sub 0) ribbon parachutes, and the remaining four are standard G-12 cargo parachutes. This paper presents an overview of the 27.6 ft D(sub 0) ribbon parachute system employed on the MLAS flight test vehicle for coast skirt separation, fairing reorientation, and as drogue parachutes for the CM after separation from the fairing. Discussion will include: the process used to select this design, previously proven as a spin/stall recovery parachute; descriptions of all components of the parachute system; the minor modifications necessary to adapt the parachute to the MLAS program; the techniques used to analyze the parachute for the multiple roles it performs; a discussion of the rigging techniques used to interface the parachute system to the vehicle; and a brief description of how the evolution of the program affected parachute usage and analysis. An overview of the Objective system, rationale for the MLAS approach and the future of the program will also be presented. We hope to have flight test results to report at the time of the Conference Presentation.

In 2007, the NASA Exploration Systems Mission Directorate (ESMD) chartered the NASA Engineering Safety Center (NESC) to demonstrate an alternate launch abort concept as risk mitigation for the Orion project's baseline "tower" design. On July 8, 2009, a full scale, passive aerodynamically stabilized Max Launch Abort System (MLAS) pad abort demonstrator was successfully launched from NASA Goddard Space Flight Center's Wallops Flight Facility. Aerodynamic close-outs were required to cover openings on the MLAS fairing to prevent aerodynamic flow-through and to maintain the MLAS OML surface shape. Two-ply duct tape covers were designed to meet these needs. The duct tape used was a high strength fiber reinforced duct tape with a rubberized adhesive that demonstrated 4.6 lb/in adhesion strength to the unpainted fiberglass fairing. Adhesion strength was observed to increase as a function of time. The covers were analyzed and experimentally tested to demonstrate their ability to maintain integrity under anticipated vehicle ascent pressure loads and to not impede firing of the drogue chute mortars. Testing included vacuum testing and a mortar fire test. Tape covers were layed-up on thin Teflon sheets to facilitate installation on the vehicle. Custom cut foam insulation board was used to fill mortar hole and separation joint cavities and provide support to the applied tape covers. Flight test results showed that the tape covers remained adhered during flight.

2011-01-01

In order to mitigate catastrophic failures on future generation space vehicles, engineers at the National Aeronautics and Space Administration have begun to integrate a novel crew abort systems that could pull a crew module away in case of an emergency at the launch pad or during ascent. The Max Launch Abort System (MLAS) is a recent test vehicle that was designed as an alternative to the baseline Orion Launch Abort System (LAS) to demonstrate the performance of a "tower-less" LAS configuration under abort conditions. The MLAS II test vehicle will execute a propulsive coast stabilization maneuver during abort to control the vehicles trajectory and thrust. To accomplish this, the spacecraft will integrate an Attitude Control System (ACS) with eight hypergolic monomethyl hydrazine liquid propulsion engines that are capable of operating in a quick pulsing mode. Two main elements of the ACS include a propellant distribution subsystem and a pressurization subsystem to regulate the flow of pressurized gas to the propellant tanks and the engines. The CAD assembly of the Attitude Control System (ACS) was configured and integrated into the Launch Abort Vehicle (LAV) design. A dynamic random vibration analysis was conducted on the Main Propulsion System (MPS) helium pressurization panels to assess the response of the panel and its components under increased gravitational acceleration loads during flight. The results indicated that the panels fundamental and natural frequencies were farther from the maximum Acceleration Spectral Density (ASD) vibrations which were in the range of 150-300 Hz. These values will direct how the components will be packaged in the vehicle to reduce the effects high gravitational loads.

The National Aeronautics and Space Administration (NASA) Engineering and Safety Center (NESC) was tasked to develop an alternate, tower-less launch abort system (LAS) as risk mitigation for the Orion Project. The successful pad abort flight demonstration test in July 2009 of the "Max" launch abort system (MLAS) provided data critical to the design of future LASs, while demonstrating the Agency s ability to rapidly design, build and fly full-scale hardware at minimal cost in a "virtual" work environment. Limited funding and an aggressive schedule presented a challenge for testing of the complex MLAS system. The successful pad abort flight demonstration test was attributed to the project s systems engineering and integration process, which included: a concise definition of, and an adherence to, flight test objectives; a solid operational concept; well defined performance requirements, and a test program tailored to reducing the highest flight test risks. The testing ranged from wind tunnel validation of computational fluid dynamic simulations to component ground tests of the highest risk subsystems. This paper provides an overview of the testing/risk management approach and methodologies used to understand and reduce the areas of highest risk - resulting in a successful flight demonstration test.

The NASA Engineering and Safety Center (NESC) is an independent engineering analysis and test organization providing support across the range of NASA programs. In 2007 NASA was developing the launch escape system for the Orion spacecraft that was evolved from the traditional tower-configuration escape systems used for the historic Mercury and Apollo spacecraft. The NESC was tasked, as a programmatic risk-reduction effort to develop and flight test an alternative to the Orion baseline escape system concept. This project became known as the Max Launch Abort System (MLAS), named in honor of Maxime Faget, the developer of the original Mercury escape system. Over the course of approximately two years the NESC performed conceptual and tradeoff analyses, designed and built full-scale flight test hardware, and conducted a flight test demonstration in July 2009. Since the flight test, the NESC has continued to further develop and refine the MLAS concept.
Comparison of Two Recent Launch Abort Platforms

2011-01-01

The development of new and safer manned space vehicles is a top priority at NASA. Recently two different approaches of how to accomplish this mission of keeping astronauts safe was successfully demonstrated. With work already underway on an Apollo-like launch abort system for the Orion Crew Exploration Vehicle (CEV), an alternative design concept named the Max Launch Abort System, or MLAS, was developed as a parallel effort. The Orion system, managed by the Constellation office, is based on the design of a single solid launch abort motor in a tower positioned above the capsule. The MLAS design takes a different approach placing the solid launch abort motor underneath the capsule. This effort was led by the NASA Engineering and Safety Center (NESC). Both escape systems were designed with the Ares I Rocket as the launch vehicle and had the same primary requirement to safely propel a crew module away from any emergency event either on the launch pad or during accent. Beyond these two parameters, there was little else in common between the two projects, except that they both concluded in successful launches that will further promote the development of crew launch abort systems. A comparison of these projects from the standpoint of technical requirements; program management and flight test objectives will be done to highlight the synergistic lessons learned by two engineers who worked on each program. This comparison will demonstrate how the scope of the project architecture and management involvement in innovation should be tailored to meet the specific needs of the system under development.

A new measurement technique for determination of the center of gravity (CG) for large scale objects has been demonstrated. The experimental method was conducted as part of an LS-DYNA model validation program for the Max Launch Abort System (MLAS) crew module. The test was conducted on the full scale crew module concept at NASA Langley Research Center. Multi-camera photogrammetry was used to measure the test article in several asymmetric configurations. The objective of these measurements was to provide validation of the CG as computed from the original mechanical design. The methodology, measurement technique, and measurement results are presented.

The NASA Engineering and Safety Center initiated the Max Launch Abort System (MLAS) Project to investigate alternate crew escape system concepts that eliminate the conventional launch escape tower by integrating the escape system into an aerodynamic fairing that fully encapsulates the crew capsule and smoothly integrates with the launch vehicle. This paper proposes an ascent abort flight test for an all-propulsive towerless escape system concept that is actively controlled and sized to accommodate the Orion Crew Module. The goal of the flight test is to demonstrate a high dynamic pressure escape and to characterize jet interaction effects during operation of the attitude control thrusters at transonic and supersonic conditions. The flight-test vehicle is delivered to the required test conditions by a booster configuration selected to meet cost, manufacturability, and operability objectives. Data return is augmented through judicious design of the boost trajectory, which is optimized to obtain data at a range of relevant points, rather than just a single flight condition. Secondary flight objectives are included after the escape to obtain aerodynamic damping data for the crew module and to perform a high-altitude contingency deployment of the drogue parachutes. Both 3- and 6-degree-of-freedom trajectory simulation results are presented that establish concept feasibility, and a Monte Carlo uncertainty assessment is performed to provide confidence that test objectives can be met.
Evaluation of Two Crew Module Boilerplate Tests Using Newly Developed Calibration Metrics

Horta, Lucas G.; Reaves, Mercedes C.

2012-01-01

The paper discusses a application of multi-dimensional calibration metrics to evaluate pressure data from water drop tests of the Max Launch Abort System (MLAS) crew module boilerplate. Specifically, three metrics are discussed: 1) a metric to assess the probability of enveloping the measured data with the model, 2) a multi-dimensional orthogonality metric to assess model adequacy between test and analysis, and 3) a prediction error metric to conduct sensor placement to minimize pressure prediction errors. Data from similar (nearly repeated) capsule drop tests shows significant variability in the measured pressure responses. When compared to expected variability using model predictions, it is demonstrated that the measured variability cannot be explained by the model under the current uncertainty assumptions.

2015-10-01

We demonstrate a simple route to fabricate closed-packed infrared (IR) silicon microlens arrays (MLAs) based on femtosecond laser irradiation assisted by wet etching method. The fabricated MLAs show high fill factor, smooth surface and good uniformity. They can be used as optical devices for IR applications. The exposure and etching parameters are optimized to obtain reproducible microlens with hexagonal and rectangular arrangements. The surface roughness of the concave MLAs is only 56 nm. This presented method is a maskless process and can flexibly change the size, shape and the fill factor of the MLAs by controlling the experimental parameters. The concave MLAs on silicon can work in IR region and can be used for IR sensors and imaging applications.
An E3 Ligase Affects the NLR Receptor Stability and Immunity to Powdery Mildew1

2016-01-01

Following the detection of pathogen cognate effectors, plant Nod-like receptors (NLRs) trigger isolate-specific immunity that is generally associated with cell death. The regulation of NLR stability is important to ensure effective immunity. In barley (Hordeum vulgare), the allelic Mildew locus A (MLA) receptors mediate isolate-specific disease resistance against powdery mildew fungus (Blumeria graminis f. sp. hordei). Currently, how MLA stability is controlled remains unknown. Here, we identified an MLA-interacting RING-type E3 ligase, MIR1, that interacts with several MLAs. We showed that the carboxyl-terminal TPR domain of MIR1 mediates the interaction with the coiled-coil domain-containing region of functional MLAs, such as MLA1, MLA6, and MLA10, but not with that of the nonfunctional MLA18-1. MIR1 can ubiquitinate the amino-terminal region of MLAs in vitro and promotes the proteasomal degradation of MLAs in vitro and in planta. Both proteasome inhibitor treatment and virus-induced gene silencing-mediated MIR1 silencing significantly increased MLA abundance in barley transgenic lines. Furthermore, overexpression of MIR1 specifically compromised MLA-mediated disease resistance in barley, while coexpression of MIR1 and MLA10 attenuated MLA10-induced cell death signaling in Nicotiana benthamiana. Together, our data reveal a mechanism for the control of the stability of MLA immune receptors and for the attenuation of MLA-triggered defense signaling by a RING-type E3 ligase via the ubiquitin proteasome system.

2017-05-18

The relationships between the fatigue crack growth rate ( d a / d N ) and stress intensity factor range ( Δ K ) are not always linear even in the Paris region. The stress ratio effects on fatigue crack growth rate are diverse in different materials. However, most existing fatigue crack growth models cannot handle these nonlinearities appropriately. The machine learning method provides a flexible approach to the modeling of fatigue crack growth because of its excellent nonlinear approximation and multivariable learning ability. In this paper, a fatigue crack growth calculation method is proposed based on three different machine learning algorithms (MLAs): extreme learning machine (ELM), radial basis function network (RBFN) and genetic algorithms optimized back propagation network (GABP). The MLA based method is validated using testing data of different materials. The three MLAs are compared with each other as well as the classical two-parameter model ( K * approach). The results show that the predictions of MLAs are superior to those of K * approach in accuracy and effectiveness, and the ELM based algorithms show overall the best agreement with the experimental data out of the three MLAs, for its global optimization and extrapolation ability.

Minimum Ages of Legal Access for Tobacco in the United States From 1863 to 2015

PubMed Central

Glantz, Stanton A.

2016-01-01

In the United States, state laws establish a minimum age of legal access (MLA) for most tobacco products at 18 years. We reviewed the history of these laws with internal tobacco industry documents and newspaper archives from 1860 to 2014. The laws appeared in the 1880s; by 1920, half of states had set MLAs of at least 21 years. After 1920, tobacco industry lobbying eroded them to between 16 and 18 years. By the 1980s, the tobacco industry viewed restoration of higher MLAs as a critical business threat. The industry’s political advocacy reflects its assessment that recruiting youth smokers is critical to its survival. The increasing evidence on tobacco addiction suggests that restoring MLAs to 21 years would reduce smoking initiation and prevalence, particularly among those younger than 18 years. PMID:27196658

Multi-wavelength semiconductor laser arrays (MLAs) have wide applications in wavelength multiplexing division (WDM) networks. In spite of their tremendous potential, adoption of the MLA has been hampered by a number of issues, particularly wavelength precision and fabrication cost. In this paper, we report high channel count MLAs in which the wavelengths of each channel can be determined precisely through low-cost standard μm-level photolithography/holographic lithography and the reconstruction-equivalent-chirp (REC) technique. 60-wavelength MLAs with good wavelength spacing uniformity have been demonstrated experimentally, in which nearly 83% lasers are within a wavelength deviation of ±0.20 nm, corresponding to a tolerance of ±0.032 nm in the period pitch. As a result of employing the equivalent phase shift technique, the single longitudinal mode (SLM) yield is nearly 100%, while the theoretical yield of standard DFB lasers is only around 33.3%.

Acute pancreatitis (AP) is a complex disease with multiple aetiological factors, wide ranging severity, and multiple challenges to effective triage and management. Databases, data mining and machine learning algorithms (MLAs), including artificial neural networks (ANNs), may assist by storing and interpreting data from multiple sources, potentially improving clinical decision-making. 1) Identify database technologies used to store AP data, 2) collate and categorise variables stored in AP databases, 3) identify the MLA technologies, including ANNs, used to analyse AP data, and 4) identify clinical and non-clinical benefits and obstacles in establishing a national or international AP database. Comprehensive systematic search of online reference databases. The predetermined inclusion criteria were all papers discussing 1) databases, 2) data mining or 3) MLAs, pertaining to AP, independently assessed by two reviewers with conflicts resolved by a third author. Forty-three papers were included. Three data mining technologies and five ANN methodologies were reported in the literature. There were 187 collected variables identified. ANNs increase accuracy of severity prediction, one study showed ANNs had a sensitivity of 0.89 and specificity of 0.96 six hours after admission--compare APACHE II (cutoff score ≥8) with 0.80 and 0.85 respectively. Problems with databases were incomplete data, lack of clinical data, diagnostic reliability and missing clinical data. This is the first systematic review examining the use of databases, MLAs and ANNs in the management of AP. The clinical benefits these technologies have over current systems and other advantages to adopting them are identified. Copyright © 2013 IAP and EPC. Published by Elsevier B.V. All rights reserved.

2018-06-01

This work presents an economic and controllable fabricating method of high numerical aperture (NA) polymer microlens array (MLA) based on ink-jetting technology. The MLAs are ink-jetted to align on micro platforms patterned flexible PDMS substrate. The shape of a sole lens is constructed by the ink-jetted pre-cured polymer volume confined on a micro platform. In this way, MLAs with targeted geometries-as well as tailored optical characteristics-can be printed, leading to freely designed optical properties. High NA from 0.446 to 0.885 and focal lengths between 99.26 μm and 39.45 μm are demonstrated, confirming theoretical predictions. Particularly, both the simulations and experimental measurements in optical properties are carried out, demonstrating that microlenses with shapes beyond a hemisphere (CA > 90°) exhibits higher light utilization efficiency and wider viewing angle. Meanwhile, the MLAs are fabricated on flexible PDMS substrates and can be attached to other curved surfaces for wider field of view imaging and higher sensitivity.
Prediction of Aerosol Optical Depth in West Asia: Machine Learning Methods versus Numerical Models

2017-04-01

Dust-prone areas of West Asia are releasing increasingly large amounts of dust particles during warm months. Because of the lack of ground-based observations in the region, this phenomenon is mainly monitored through remotely sensed aerosol products. The recent development of mesoscale Numerical Models (NMs) has offered an unprecedented opportunity to predict dust emission, and, subsequently Aerosol Optical Depth (AOD), at finer spatial and temporal resolutions. Nevertheless, the significant uncertainties in input data and simulations of dust activation and transport limit the performance of numerical models in dust prediction. The presented study aims to evaluate if machine-learning algorithms (MLAs), which require much less computational expense, can yield the same or even better performance than NMs. Deep blue (DB) AOD, which is observed by satellites but also predicted by MLAs and NMs, is used for validation. We concentrate our evaluations on the over dry Iraq plains, known as the main origin of recently intensified dust storms in West Asia. Here we examine the performance of four MLAs including Linear regression Model (LM), Support Vector Machine (SVM), Artificial Neural Network (ANN), Multivariate Adaptive Regression Splines (MARS). The Weather Research and Forecasting model coupled to Chemistry (WRF-Chem) and the Dust REgional Atmosphere Model (DREAM) are included as NMs. The MACC aerosol re-analysis of European Centre for Medium-range Weather Forecast (ECMWF) is also included, although it has assimilated satellite-based AOD data. Using the Recursive Feature Elimination (RFE) method, nine environmental features including soil moisture and temperature, NDVI, dust source function, albedo, dust uplift potential, vertical velocity, precipitation and 9-month SPEI drought index are selected for dust (AOD) modeling by MLAs. During the feature selection process, we noticed that NDVI and SPEI are of the highest importance in MLAs predictions. The data set was divided into a training (2003-2010) and a testing (2011-2013) subset. The evaluation using the two subsets shows that ANN outperformed all other MLAs and NMs. Verified to monthly mean MODIS DB AOD, ANN yielded a Spearman correlation coefficient (SCC) of 0.74, whereas SCC of 0.71 was allotted to WRF-chem simulations, as the most successful NM. In terms of simulation accuracy, SVM and MARS have yielded the lowest bias (-0.001) and RMSE (0.16). DREAM showed the poorest performance with a SCC of 0.52, a bias of -0.17 and a RMSE of 0.29.
Fabrication of microlens array and bifocal microlens using the methods of laser ablation and solvent reflow

Based on the techniques of laser microdrilling and solvent reflow, this study reports on a straightforward approach for fabricating plastic microlens arrays (MLAs). First, we use the ArF excimer laser to drill microholes on a polymethylmethacrylate plate for defining the lens number, initial depth, and diameter. The propylene glycol monomethyl ether acetate solvent is then employed to regulate the surface profile that leads to a resulting negative (concave) MLA. The corresponding positive (convex), polydimethyl-siloxane MLA is obtained by the soft-replica-molding technique. Through varying the pattern size and period on the mask and the light intensity for laser drilling and regulating the solvent in the reflow process, we exhibit the feasibility of making MLAs with various sizes and shapes. By modifying the laser ablation step to drill two microholes with different diameters and depths at two levels, we fabricate a bifocal microlens. The obtained microlenses have excellent surface and optical properties: surface roughness down to several nanometers and focal lengths varying from hundreds to thousands of micrometers. This approach is flexible for constructing microlenses with various sizes and shapes and can fabricate MLAs with a high fill factor.

The sensitivity of searches for astrophysical transients in data from the Laser Interferometer Gravitationalwave Observatory (LIGO) is generally limited by the presence of transient, non-Gaussian noise artifacts, which occur at a high-enough rate such that accidental coincidence across multiple detectors is non-negligible. Furthermore, non-Gaussian noise artifacts typically dominate over the background contributed from stationary noise. These "glitches" can easily be confused for transient gravitational-wave signals, and their robust identification and removal will help any search for astrophysical gravitational-waves. We apply Machine Learning Algorithms (MLAs) to the problem, using data from auxiliary channels within the LIGO detectors that monitor degrees of freedom unaffected by astrophysical signals. Terrestrial noise sources may manifest characteristic disturbances in these auxiliary channels, inducing non-trivial correlations with glitches in the gravitational-wave data. The number of auxiliary-channel parameters describing these disturbances may also be extremely large; high dimensionality is an area where MLAs are particularly well-suited. We demonstrate the feasibility and applicability of three very different MLAs: Artificial Neural Networks, Support Vector Machines, and Random Forests. These classifiers identify and remove a substantial fraction of the glitches present in two very different data sets: four weeks of LIGO's fourth science run and one week of LIGO's sixth science run. We observe that all three algorithms agree on which events are glitches to within 10% for the sixth science run data, and support this by showing that the different optimization criteria used by each classifier generate the same decision surface, based on a likelihood-ratio statistic. Furthermore, we find that all classifiers obtain similar limiting performance, suggesting that most of the useful information currently contained in the auxiliary channel parameters we extract is already being used. Future performance gains are thus likely to involve additional sources of information, rather than improvements in the MLAs themselves.

Optical and electronic processes in organic photovoltaic devices

NASA Astrophysics Data System (ADS)

Myers, Jason David

Organic photovoltaic devices (OPVs) have become a promising research field. OPVs have intrinsic advantages over conventional inorganic technologies: they can be produced from inexpensive source materials using high-throughput techniques on a variety of substrates, including glass and flexible plastics. However, organic semiconductors have radically different operation characteristics which present challenges to achieving high performance OPVs. To increase the efficiency of OPVs, knowledge of fundamental operation principles is crucial. Here, the photocurrent behavior of OPVs with different heterojunction architectures was studied using synchronous photocurrent detection. It was revealed that photocurrent is always negative in planar and planar-mixed heterojunction devices as it is dominated by photocarrier diffusion. In mixed layer devices, however, the drift current dominates except at biases where the internal electric field is negligible. At these biases, the diffusion current dominates, exhibiting behavior that is correlated to the optical interference patterns within the device active layer. Further, in an effort to increase OPV performance without redesigning the active layer, soft-lithographically stamped microlens arrays (MLAs) were developed and applied to a variety of devices. MLAs refract and reflect incident light, giving light a longer path length through the active layer compared to a device without a MLA; this increases absorption and photocurrent. The experimentally measured efficiency enhancements range from 10 to 60%, with the bulk of this value coming from increased photocurrent. Additionally, because the enhancement is dependent on the substrate/air interface and not the active layer, MLAs are applicable to all organic material systems. Finally, novel architectures for bifunctional organic optoelectronic devices (BFDs), which can function as either an OPV or an organic light emitting device (OLED), were investigated. Because OPVs and OLEDs have inherently opposing operation principles, BFDs suffer from poor performance. A new architecture was developed to incorporate the phosphorescent emitter platinum octaethylporphine (PtOEP) into a rubrene/C60 bilayer BFD to make more efficient use of injected carriers. While the emission was localized to a PtOEP emitter layer by an electron permeable exciton blocking layer of N, N'-bis(naphthalen-1-yl)-N,N'-bis(phenyl)-benzidine (NPB), total performance was not improved. From these experiments, a new understanding of the material requirements for BFDs was obtained.

In this paper, 3 types of laser beam scanner are introduced. One is transmissive beam scanner, which is composed of convex and concave microlens arrays (MLAs). By moving the concave lens in the plane vertical to the optical axis, the incident beam can be deflected in two dimensions. Those two kinds of MLAs are fabricated by thermal reflow and replication process. A set of mechanical scanner frame is fabricated with the two MLAs assembling in it. The testing result shown that the beam deflection angles are 9.5° and 9.6°, in the 2 dimension(2D) with the scanning frequency of 2 HZ and 8 HZ, respectively. The second type of laser beam scanner is actuated by voice coil actuators (VCAs). Based on ANSOFT MAXWELL software, we have designed VCAs with small size and large force which have optimized properties. The model of VCAs is built using AutoCAD and is analyzed by Ansoft maxwell. According to the simulation results, high performance VCAs are fabricated and tested. The result is that the force of the VCAs is 6.39N/A, and the displacement is +/-2.5mm. A set up of beam scanner is fabricated and actuated by the designed VCAs. The testing result shown that the two dimensional scanning angle is 15° and 10° respectively at the frequency of 60HZ. The two dimensional scanning angle is 8.3° and 6° respectively at the frequency of 100HZ. The third type of scanner is actuated by amplified piezoelectric actuators (APAs). The scanning mirror is actuated by the piezoelectric (PZ) actuators with the scanning frequency of 700HZ, 250HZ and 87HZ respectively. The optical scanning angle is +/-0.5° at the three frequencies.

The majority of abortions in Colombia continue to take place outside the formal health system under a range of conditions, with the majority of women obtaining misoprostol from a thriving black market for the drug and self-administering the medication. We conducted a cost analysis to compare the costs to the health system of three approaches to the provision of abortion care in Colombia: post-abortion care for complications of unsafe abortions, and for legal abortions in a health facility, misoprostol-only medical abortion and vacuum aspiration abortion. Hospital billing records from three institutions, two large maternity hospitals and one specialist reproductive health clinic, were analysed for procedure and complication rates, and costs by diagnosis. The majority of visits (94%) were to the two hospitals for post-abortion care; the other 6% were for legal abortions. Only one minor complication was found among the women having legal abortions, a complication rate of less than 1%. Among the women presenting for post-abortion care, 5% had complications during their treatment, mainly from infection or haemorrhage. Legal abortions were associated not only with far fewer complications for women, but also lower costs for the health system than for post-abortion care. We calculated based on our findings that for every 1,000 women receiving post-abortion care instead of a legal abortion within the health system, 16 women experienced avoidable complications, and the health system spent US $48,000 managing them. Increasing women's access to safe abortion care would not only reduce complications for women, but would also be a cost-saving strategy for the health system.

Rapid 2D-to-3D conversion

NASA Astrophysics Data System (ADS)

Harman, Philip V.; Flack, Julien; Fox, Simon; Dowley, Mark

2002-05-01

The conversion of existing 2D images to 3D is proving commercially viable and fulfills the growing need for high quality stereoscopic images. This approach is particularly effective when creating content for the new generation of autostereoscopic displays that require multiple stereo images. The dominant technique for such content conversion is to develop a depth map for each frame of 2D material. The use of a depth map as part of the 2D to 3D conversion process has a number of desirable characteristics: 1. The resolution of the depth may be lower than that of the associated 2D image. 2. It can be highly compressed. 3. 2D compatibility is maintained. 4. Real time generation of stereo, or multiple stereo pairs, is possible. The main disadvantage has been the laborious nature of the manual conversion techniques used to create depth maps from existing 2D images, which results in a slow and costly process. An alternative, highly productive technique has been developed based upon the use of Machine Leaning Algorithm (MLAs). This paper describes the application of MLAs to the generation of depth maps and presents the results of the commercial application of this approach.

This suggests that most of the useful information currently extracted from the auxiliary channels is already described by this model. Future performance gains are thus likely to involve additional sources of information, rather than improvements in the classification algorithms themselves. We discuss several plausible sources of such new information as well as the ways of propagating it through the classifiers into gravitational-wave searches.

Aborts during the critical ascent flight phase require the design and operation of Orion Crew Exploration Vehicle (CEV) systems to escape from the Crew Launch Vehicle (CLV) and return the crew safely to the Earth. To accomplish this requirement of continuous abort coverage, CEV ascent abort modes are being designed and analyzed to accommodate the velocity, altitude, atmospheric, and vehicle configuration changes that occur during ascent. Aborts from the launch pad to early in the flight of the CLV second stage are performed using the Launch Abort System (LAS). During this type of abort, the LAS Abort Motor is used to pull the Crew Module (CM) safely away from the CLV and Service Module (SM). LAS abort guidance and control studies and design trades are being conducted so that more informed decisions can be made regarding the vehicle abort requirements, design, and operation. This paper presents an overview of the Orion CEV, an overview of the LAS ascent abort mode, and a summary of key LAS abort analysis methods and results.

Machine learning algorithms for the creation of clinical healthcare enterprise systems

Mandal, Indrajit

2017-10-01

Clinical recommender systems are increasingly becoming popular for improving modern healthcare systems. Enterprise systems are persuasively used for creating effective nurse care plans to provide nurse training, clinical recommendations and clinical quality control. A novel design of a reliable clinical recommender system based on multiple classifier system (MCS) is implemented. A hybrid machine learning (ML) ensemble based on random subspace method and random forest is presented. The performance accuracy and robustness of proposed enterprise architecture are quantitatively estimated to be above 99% and 97%, respectively (above 95% confidence interval). The study then extends to experimental analysis of the clinical recommender system with respect to the noisy data environment. The ranking of items in nurse care plan is demonstrated using machine learning algorithms (MLAs) to overcome the drawback of the traditional association rule method. The promising experimental results are compared against the sate-of-the-art approaches to highlight the advancement in recommendation technology. The proposed recommender system is experimentally validated using five benchmark clinical data to reinforce the research findings.
J-2X Abort System Development

NASA Technical Reports Server (NTRS)

Santi, Louis M.; Butas, John P.; Aguilar, Robert B.; Sowers, Thomas S.

2008-01-01

The J-2X is an expendable liquid hydrogen (LH2)/liquid oxygen (LOX) gas generator cycle rocket engine that is currently being designed as the primary upper stage propulsion element for the new NASA Ares vehicle family. The J-2X engine will contain abort logic that functions as an integral component of the Ares vehicle abort system. This system is responsible for detecting and responding to conditions indicative of impending Loss of Mission (LOM), Loss of Vehicle (LOV), and/or catastrophic Loss of Crew (LOC) failure events. As an earth orbit ascent phase engine, the J-2X is a high power density propulsion element with non-negligible risk of fast propagation rate failures that can quickly lead to LOM, LOV, and/or LOC events. Aggressive reliability requirements for manned Ares missions and the risk of fast propagating J-2X failures dictate the need for on-engine abort condition monitoring and autonomous response capability as well as traditional abort agents such as the vehicle computer, flight crew, and ground control not located on the engine. This paper describes the baseline J-2X abort subsystem concept of operations, as well as the development process for this subsystem. A strategy that leverages heritage system experience and responds to an evolving engine design as well as J-2X specific test data to support abort system development is described. The utilization of performance and failure simulation models to support abort system sensor selection, failure detectability and discrimination studies, decision threshold definition, and abort system performance verification and validation is outlined. The basis for abort false positive and false negative performance constraints is described. Development challenges associated with information shortfalls in the design cycle, abort condition coverage and response assessment, engine-vehicle interface definition, and abort system performance verification and validation are also discussed.
Computer-aided modeling and prediction of performance of the modified Lundell class of alternators in space station solar dynamic power systems

The main purpose of this project is the development of computer-aided models for purposes of studying the effects of various design changes on the parameters and performance characteristics of the modified Lundell class of alternators (MLA) as components of a solar dynamic power system supplying electric energy needs in the forthcoming space station. Key to this modeling effort is the computation of magnetic field distribution in MLAs. Since the nature of the magnetic field is three-dimensional, the first step in the investigation was to apply the finite element method to discretize volume, using the tetrahedron as the basic 3-D element. Details of the stator 3-D finite element grid are given. A preliminary look at the early stage of a 3-D rotor grid is presented.
Design of Launch Abort System Thrust Profile and Concept of Operations

NASA Technical Reports Server (NTRS)

Litton, Daniel; O'Keefe, Stephen A.; Winski, Richard G.; Davidson, John B.

2008-01-01

This paper describes how the Abort Motor thrust profile has been tailored and how optimizing the Concept of Operations on the Launch Abort System (LAS) of the Orion Crew Exploration Vehicle (CEV) aides in getting the crew safely away from a failed Crew Launch Vehicle (CLV). Unlike the passive nature of the Apollo system, the Orion Launch Abort Vehicle will be actively controlled, giving the program a more robust abort system with a higher probability of crew survival for an abort at all points throughout the CLV trajectory. By optimizing the concept of operations and thrust profile the Orion program will be able to take full advantage of the active Orion LAS. Discussion will involve an overview of the development of the abort motor thrust profile and the current abort concept of operations as well as their effects on the performance of LAS aborts. Pad Abort (for performance) and Maximum Drag (for separation from the Launch Vehicle) are the two points that dictate the required thrust and shape of the thrust profile. The results in this paper show that 95% success of all performance requirements is not currently met for Pad Abort. Future improvements to the current parachute sequence and other potential changes will mitigate the current problems, and meet abort performance requirements.
Orion Launch Abort System Performance During Exploration Flight Test 1

2015-01-01

The Orion Launch Abort System Office is taking part in flight testing to enable certification that the system is capable of delivering the astronauts aboard the Orion Crew Module to a safe environment during both nominal and abort conditions. Orion is a NASA program, Exploration Flight Test 1 is managed and led by the Orion prime contractor, Lockheed Martin, and launched on a United Launch Alliance Delta IV Heavy rocket. Although the Launch Abort System Office has tested the critical systems to the Launch Abort System jettison event on the ground, the launch environment cannot be replicated completely on Earth. During Exploration Flight Test 1, the Launch Abort System was to verify the function of the jettison motor to separate the Launch Abort System from the crew module so it can continue on with the mission. Exploration Flight Test 1 was successfully flown on December 5, 2014 from Cape Canaveral Air Force Station's Space Launch Complex 37. This was the first flight test of the Launch Abort System preforming Orion nominal flight mission critical objectives. The abort motor and attitude control motors were inert for Exploration Flight Test 1, since the mission did not require abort capabilities. Exploration Flight Test 1 provides critical data that enable engineering to improve Orion's design and reduce risk for the astronauts it will protect as NASA continues to move forward on its human journey to Mars. The Exploration Flight Test 1 separation event occurred at six minutes and twenty seconds after liftoff. The separation of the Launch Abort System jettison occurs once Orion is safely through the most dynamic portion of the launch. This paper will present a brief overview of the objectives of the Launch Abort System during a nominal Orion flight. Secondly, the paper will present the performance of the Launch Abort System at it fulfilled those objectives. The lessons learned from Exploration Flight Test 1 and the other Flight Test Vehicles will certainly contribute to the vehicle architecture of a human-rated space launch vehicle.

New York City (NYC) mandates reporting of all abortion procedures. These reports enable tracking of abortion incidence and underpin programs, policy, and research. Since January 2011, the majority of abortion facilities must report electronically. We conducted an evaluation of NYC's abortion reporting system and its transition to electronic reporting. We summarize the evaluation methodology and results and draw lessons relevant to other vital statistics and public health reporting systems. The evaluation followed Centers for Disease Control and Prevention guidelines for evaluating public health surveillance systems. We interviewed key stakeholders and conducted a data provider survey. In addition, we compared the system's abortion counts with external estimates and calculated the proportion of missing and invalid values for each variable on the report form. Finally, we assessed the process for changing the report form and estimated system costs. NYC Health Department's Bureau of Vital Statistics. Usefulness, simplicity, flexibility, data quality, acceptability, sensitivity, timeliness, and stability of the abortion reporting system. Ninety-five percent of abortion data providers considered abortion reporting important; 52% requested training regarding the report form. Thirty percent reported problems with electronic biometric fingerprint certification, and 18% reported problems with the electronic system's stability. Estimated system sensitivity was 88%. Of 17 variables, education and ancestry had more than 5% missing values in 2010. Changing the electronic reporting module was costly and time-consuming. System operating costs were estimated at $80 136 to $89 057 annually. The NYC abortion reporting system is sensitive and provides high-quality data, but opportunities for improvement include facilitating biometric certification, increasing electronic platform stability, and conducting ongoing outreach and training for data providers. This evaluation will help data users determine the degree of confidence that should be placed on abortion data. In addition, the evaluation results are applicable to other vital statistics reporting and surveillance systems.
OPERATIONAL EXPERIENCE WITH BEAM ABORT SYSTEM FOR SUPERCONDUCTING UNDULATOR QUENCH MITIGATION*

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

Harkay, Katherine C.; Dooling, Jeffrey C.; Sajaev, Vadim

A beam abort system has been implemented in the Advanced Photon Source storage ring. The abort system works in tandem with the existing machine protection system (MPS), and its purpose is to control the beam loss location and, thereby, minimize beam loss-induced quenches at the two superconducting undulators (SCUs). The abort system consists of a dedicated horizontal kicker designed to kick out all the bunches in a few turns after being triggered by MPS. The abort system concept was developed on the basis of single- and multi-particle tracking simulations using elegant and bench measurements of the kicker pulse. Performance ofmore » the abort system—kick amplitudes and loss distributions of all bunches—was analyzed using beam position monitor (BPM) turn histories, and agrees reasonably well with the model. Beam loss locations indicated by the BPMs are consistent with the fast fiber-optic beam loss monitor (BLM) diagnostics described elsewhere [1,2]. Operational experience with the abort system, various issues that were encountered, limitations of the system, and quench statistics are described.« less

The RHIC Beam Abort Kicker Power Supply Systems commissioning experience and the remaining issues will be reported in this paper. The RHIC Blue Ring Beam Abort Kicker Power Supply System initial commissioning took place in June 1999. Its identical system in Yellow Ring was brought on line during Spring 2000. Each of the RHIC Beam Abort Kicker Power Supply Systems consists of five high voltage modulators and subsystems. These systems are critical devices for RHIC machine protection and environmental protection. They are required to be effective, reliable and operating with sufficient redundancy to safely abort the beam to its beammore » dump at the end of accumulation or at any time when they are commanded. To deflect 66 GeV ion beam to the beam absorbers, the RHIC Beam Abort Kicker Power Supply Systems were operated at 22 kV level. The RHIC 2000 commissioning run was very successful.« less

We assessed the effect of a telemedicine model providing medical abortion on service delivery in a clinic system in Iowa. We reviewed Iowa vital statistic data and billing data from the clinic system for all abortion encounters during the 2 years prior to and after the introduction of telemedicine in June 2008 (n = 17,956 encounters). We calculated the distance from the patient's residential zip code to the clinic and to the closest clinic providing surgical abortion. The abortion rate decreased in Iowa after telemedicine introduction, and the proportion of abortions in the clinics that were medical increased from 46% to 54%. After telemedicine was introduced, and with adjustment for other factors, clinic patients had increased odds of obtaining both medical abortion and abortion before 13 weeks' gestation. Although distance traveled to the clinic decreased only slightly, women living farther than 50 miles from the nearest clinic offering surgical abortion were more likely to obtain an abortion after telemedicine introduction. Telemedicine could improve access to medical abortion, especially for women living in remote areas, and reduce second-trimester abortion.

Legal restrictions on abortion access impact the safety and timing of abortion. Women affected by these laws face barriers to safe care that often result in abortion being delayed. Second-trimester abortion affects vulnerable groups of women disproportionately and is often more difficult to access. In Argentina, where abortion is legally restricted except in cases of rape or threat to the health of the woman, the Socorristas en Red, a feminist network, offers a model of accompaniment wherein they provide information and support to women seeking second-trimester abortions. This qualitative analysis aimed to understand Socorristas' experiences supporting women who have second-trimester medication abortion outside the formal health care system. We conducted 2 focus groups with 16 Socorristas in total to understand experiences accompanying women having second-trimester medication abortion who were at 14-24 weeks' gestational age. We performed a thematic analysis of the data and present key themes in this article. The Socorristas strived to ensure that women had the power of choice in every step of their abortion. These cases required more attention and logistical, legal and medical risks than first-trimester care. The Socorristas learned how to help women manage the possibility of these risks and were comfortable providing this support. They understood their work as activism through which they aim to destigmatize abortion and advocate against patriarchal systems denying the right to abortion. Socorrista groups have shown that they can provide supportive, women-centered accompaniment during second-trimester medication abortions outside the formal health care system in a setting where abortion access is legally restricted. Second-trimester self-use of medication abortion outside of the formal health system supported by feminist activist groups could provide an alternative model for second-trimester care worldwide. More research is needed to document the safety and effectiveness of this accompaniment service-provision model. Copyright © 2017 The Authors. Published by Elsevier Inc. All rights reserved.
Health system reform and safe abortion: a case study of Mongolia.

Unsafe abortion serves as a marker of global inequity as it is concentrated in the developing world where the poorest and most vulnerable women live. While liberalisation of abortion law is essential to the reduction of unsafe abortion, a number of challenges exist beyond this important step. This paper investigates how popular health system reforms consonant with neoliberal agendas can challenge access to safe abortion. We use Mongolia, a country that has liberalised abortion law, yet, limited access to safe abortion, as a case study. Mongolia embraced market reforms in 1990 and subsequently reformed its health system. We document how common reforms in the areas of finance and regulation can compromise the safety of abortions as they foster challenges that include inconsistencies in service delivery that further foment health inequities, adoption of reproductive health programmes that are incompatible with the local sociocultural context, unregulated growth of the private sector and poor enforcement of standards and technical guidelines for safe abortion. We then discuss how this case study suggests the conversations that reproductive health policy-makers must have with those engineering health sector reform to ensure access to safe abortion in a liberalised environment.

During the ascent flight phase of NASA s Constellation Program, the Ares launch vehicle propels the Orion crew vehicle to an agreed to insertion target. If a failure occurs at any point in time during ascent then a system must be in place to abort the mission and return the crew to a safe landing with a high probability of success. To achieve continuous abort coverage one of two sets of effectors is used. Either the Launch Abort System (LAS), consisting of the Attitude Control Motor (ACM) and the Abort Motor (AM), or the Service Module (SM), consisting of SM Orion Main Engine (OME), Auxiliary (Aux) Jets, and Reaction Control System (RCS) jets, is used. The LAS effectors are used for aborts from liftoff through the first 30 seconds of second stage flight. The SM effectors are used from that point through Main Engine Cutoff (MECO). There are two distinct sets of Guidance and Control (G&C) algorithms that are designed to maximize the performance of these abort effectors. This paper will outline the necessary inputs to the G&C subsystem, the preliminary design of the G&C algorithms, the ability of the algorithms to predict what abort modes are achievable, and the resulting success of the abort system. Abort success will be measured against the Preliminary Design Review (PDR) abort performance metrics and overall performance will be reported. Finally, potential improvements to the G&C design will be discussed.

Induced abortion has been legal in India on a broad range of medical and social grounds since 1980s. Often, induced abortion is resorted to as a means for contraception, and has a potential to be misused for sex selective feticide. We assessed the rates, trends, causes and determinants of induced abortions from 2008-12 in a rural community of northern India. Present study is a secondary data analysis of pregnancy outcomes at Ballabgarh Health and Demographic Surveillance System from 2008-12. The data was retrieved from the Health and Management Information System maintained at Ballabgarh. Cause of abortion was self-reported by the women who underwent abortion. Of the 11,102 pregnancies, 1,226 (11%) culminated as abortions of which 425 (3.8%) were induced abortions. Spontaneous abortion rate (7.2%) was twice that of induced abortion rate (3.8%). Both abortion rates had an increasing trend during the course of the study period. Self-reported reasons for opting for induced abortions were bleeding per vaginum (23%), unwanted pregnancy (16%), and unviable fetus diagnosed by ultrasonography (11%). Eight percent of the induced abortions were due to the female sex of the fetus. About 11% of the abortions were performed beyond 20 weeks of gestation which was the upper legal permissible gestational age for performing induced abortions in India. About 10% of the abortions were performed by unqualified practitioners. Caste, wealth index, birth order and size of the village population were the factors that were significantly associated with induced abortion. Though the abortion rate was low, the proportionate contribution of induced abortion was more than what could be expected. Unsafe and sex selective abortion, though illegal, was prevalent. Upper caste and higher socio-economic status families were more likely to opt for induced abortion.

The Crew Exploration Vehicle (CEV) is required to maintain continuous abort capability from lift off through destination arrival. This requirement is driven by the desire to provide the capability to safely return the crew to Earth after failure scenarios during the various phases of the mission. This paper addresses abort trajectory design considerations, concept of operations and guidance algorithm prototypes for the portion of the ascent trajectory following nominal jettison of the Launch Abort System (LAS) until safe orbit insertion. Factors such as abort system performance, crew load limits, natural environments, crew recovery, and vehicle element disposal were investigated to determine how to achieve continuous vehicle abort capability.

Analysis of abortion in Mexico from a juridical perspective requires recognition that Mexico as a national community participates in a double system of values. Politically it is defined as a liberal, democratic, and secular state, but culturally the Judeo-Christian ideology is dominant in all social strata. This duality complicates all juridical-penal decisions regarding abortion. Public opinion on abortion is influenced on the 1 hand by extremely conservative groups who condemn abortion as homicide, and on the other hand by groups who demand legislative reform in congruence with characteristics that define the state: an attitude of tolerance toward the different ideological-moral positions that coexist in the country. The discussion concerns the rights of women to voluntary maternity, protection of health, and to making their own decisions regarding their bodies vs. the rights of the fetus to life. The type of analysis is not objective, and conclusions depend on the ideology of the analyst. Other elements must be examined for an objective consideration of the social problem of abortion. For example, aspects related to maternal morbidity and mortality and the demographic, economic, and physical and mental health of the population would all seem to support the democratic juridical doctrine that sees the clandestine nature of abortion as the principal problem. It is also observed that the illegality of abortion does not guarantee its elimination. Desperate women will seek abortion under any circumstances. The illegality of abortion also impedes health and educational policies that would lower abortion mortality. There are various problems from a strictly juridical perspective. A correct definition of the term abortion is needed that would coincide with the medical definition. The discussion must be clearly centered on the protected juridical right and the definition of reproductive and health rights and rights to their own bodies of women. The experiences of other countries with decriminalization of abortion should also be assessed. Factors considered should include the true impunity of abortion, public health problems and socioeconomic problems generated by the state through criminalization of abortion, and the psychological and economic implications for women of the criminal status of abortion. Systems of decriminalization should be examined to decide which would be appropriate for Mexico. These systems include authorizing complete freedom of choice for the 1st trimester and permitting abortion only for specific indications. All penal codes in Mexico now use the system of abortion for specific indications. Few cases are accepted for legal pregnancy termination.

Pregnancy and the 40-Year Prison Sentence: How "Abortion Is Murder" Became Institutionalized in the Salvadoran Judicial System.

Viterna, Jocelyn; Bautista, Jose Santos Guardado

2017-06-01

Using the case of El Salvador, this article demonstrates how the anti-abortion catchphrase "abortion is murder" can become embedded in the legal practice of state judicial systems. In the 1990s, a powerful anti-abortion movement in El Salvador resulted in a new legal context that outlawed abortion in all circumstances, discouraged mobilization for abortion rights, and encouraged the prosecution of reproduction-related "crimes." Within this context, Salvadoran women initially charged with the crime of abortion were convicted of "aggravated homicide" and sentenced to up to 40 years in prison. Court documents suggest that many of these women had not undergone abortions, but had suffered naturally occurring stillbirths late in their pregnancies. Through analysis of newspaper articles and court cases, this article documents how El Salvador came to prosecute obstetrical emergencies as "murder," and concludes that activism on behalf of abortion rights is central to protecting poor pregnant women from prosecution for reproduction-related "crimes."

To describe the epidemiology of abortion in Ecuador from 2004 to 2014 and compare the prevalence between the public and the private health care systems. This is a cross-sectional analysis of the overall mortality and morbidity rate due to abortion in Ecuador, based on public health records and other government databases. From 2004 to 2014, a total of 431,614 spontaneous abortions, miscarriage and other types of abortions were registered in Ecuador. The average annual rate of abortion was 115 per 1,000 live births. The maternal mortality rate was found to be 43 per 100,000 live births. Abortion is a significant and wide-ranging problem in Ecuador. The study supports the perception that in spite of legal restrictions to abortion in Ecuador, women are still terminating pregnancies when they feel they need to do so. The public health system reported >84% of the national overall prevalence.
Vented Launch Vehicle Adaptor for a Manned Spacecraft with "Pusher" Launch Abort System

Vandervort, Robert E. (Inventor)

2017-01-01

A system, method, and apparatus for a vented launch vehicle adaptor (LVA) for a manned spacecraft with a "pusher" launch abort system are disclosed. The disclosed LVA provides a structural interface between a commercial crew vehicle (CCV) crew module/service module (CM/SM) spacecraft and an expendable launch vehicle. The LVA provides structural attachment of the module to the launch vehicle. It also provides a means to control the exhaust plume from a pusher-type launch abort system that is integrated into the module. In case of an on-pad or ascent abort, which requires the module to jettison away from the launch vehicle, the launch abort system exhaust plume must be safely directed away from critical and dangerous portions of the launch vehicle in order to achieve a safe and successful jettison.
Orion Launch Abort System Jettison Motor Performance During Exploration Flight Test 1

McCauley, Rachel J.; Davidson, John B.; Winski, Richard G.

2015-01-01

This paper presents an overview of the flight test objectives and performance of the Orion Launch Abort System during Exploration Flight Test-1. Exploration Flight Test-1, the first flight test of the Orion spacecraft, was managed and led by the Orion prime contractor, Lockheed Martin, and launched atop a United Launch Alliance Delta IV Heavy rocket. This flight test was a two-orbit, high-apogee, high-energy entry, low-inclination test mission used to validate and test systems critical to crew safety. This test included the first flight test of the Launch Abort System performing Orion nominal flight mission critical objectives. Although the Orion Program has tested a number of the critical systems of the Orion spacecraft on the ground, the launch environment cannot be replicated completely on Earth. Data from this flight will be used to verify the function of the jettison motor to separate the Launch Abort System from the crew module so it can continue on with the mission. Selected Launch Abort System flight test data is presented and discussed in the paper. Through flight test data, Launch Abort System performance trends have been derived that will prove valuable to future flights as well as the manned space program.
Abortion training at multiple sites: an unexpected curriculum for teaching systems-based practice.

In 1999, the Accreditation Council for Graduate Medical Education endorsed systems-based practice as one of six general competencies. The objective is to explore the paradigm of teaching residents systems-based practice during a women's health rotation that included abortion training in multiple settings. During a routine women's health rotation, residents from two urban family medicine residency programs received early abortion training at a high-volume abortion clinic and their continuity clinic. Thirty-min semistructured interviews were conducted with all 26 residents who rotated between July 2005 and August 2006. Transcripts were analyzed using thematic codes. Through exposure to different healthcare delivery systems, residents learned about systems-based practice, including understanding the failure of the larger system to meet patients' reproductive healthcare needs, differences between two systems, and potential systems barriers they might face as providers. Abortion training in multiple settings may serve as a paradigm for teaching systems-based practice during other rotations that include training in multiple sites.

Bovine abortion is the main clinical sign of bovine brucellosis, a disease of which France has been declared officially free since 2005. To ensure the early detection of any brucellosis outbreak, event-driven surveillance relies on the mandatory notification of bovine abortions and the brucellosis testing of aborting cows. However, the under-reporting of abortions appears frequent. Our objectives were to assess the aptitude of the bovine abortion surveillance system to detect each and every bovine abortion and to identify factors influencing the system's effectiveness. We evaluated five attributes defined by the U.S. Centers for Disease Control with a method suited to each attribute: (1) data quality was studied quantitatively and qualitatively, as this factor considerably influences data analysis and results; (2) sensitivity and representativeness were estimated using a unilist capture-recapture approach to quantify the surveillance system's effectiveness; (3) acceptability and simplicity were studied through qualitative interviews of actors in the field, given that the surveillance system relies heavily on abortion notifications by farmers and veterinarians. Our analysis showed that (1) data quality was generally satisfactory even though some errors might be due to actors' lack of awareness of the need to collect accurate data; (2) from 2006 to 2011, the mean annual sensitivity - i.e. the proportion of farmers who reported at least one abortion out of all those who detected such events - was around 34%, but was significantly higher in dairy than beef cattle herds (highlighting a lack of representativeness); (3) overall, the system's low sensitivity was related to its low acceptability and lack of simplicity. This study showed that, in contrast to policy-makers, most farmers and veterinarians perceived the risk of a brucellosis outbreak as negligible. They did not consider sporadic abortions as a suspected case of brucellosis and usually reported abortions only to identify their cause rather than to reject brucellosis. The system proved too complex, especially for beef cattle farmers, as they may fail to detect aborting cows at pasture or have difficulties catching them for sampling. By investigating critical attributes, our evaluation highlighted the surveillance system's strengths and needed improvements. We believe our comprehensive approach can be used to assess other event-driven surveillance systems. In addition, some of our recommendations on increasing the effectiveness of event-driven brucellosis surveillance may be useful in improving the notification rate for suspected cases of other exotic diseases.

The mandatory bovine abortion notification system in France aims to detect as soon as possible any resurgence of bovine brucellosis. However, under-reporting seems to be a major limitation of this system. We used a unilist capture-recapture approach to assess the sensitivity, i.e. the proportion of farmers who reported at least one abortion among those who detected such events, and representativeness of the system during 2006-2011. We implemented a zero-inflated Poisson model to estimate the proportion of farmers who detected at least one abortion, and among them, the proportion of farmers not reporting. We also applied a hurdle model to evaluate the effect of factors influencing the notification process. We found that the overall surveillance sensitivity was about 34%, and was higher in beef than dairy cattle farms. The observed increase in the proportion of notifying farmers from 2007 to 2009 resulted from an increase in the surveillance sensitivity in 2007/2008 and an increase in the proportion of farmers who detected at least one abortion in 2008/2009. These patterns suggest a raise in farmers' awareness in 2007/2008 when the Bluetongue Virus (BTV) was detected in France, followed by an increase in the number of abortions in 2008/2009 as BTV spread across the country. Our study indicated a lack of sensitivity of the mandatory bovine abortion notification system, raising concerns about the ability to detect brucellosis outbreaks early. With the increasing need to survey the zoonotic Rift Valley Fever and Q fever diseases that may also cause bovine abortions, our approach is of primary interest for animal health stakeholders to develop information programs to increase abortion notifications. Our framework combining hurdle and ZIP models may also be applied to estimate the completeness of other clinical surveillance systems.

Full-Envelope Launch Abort System Performance Analysis Methodology

Aubuchon, Vanessa V.

2014-01-01

The implementation of a new dispersion methodology is described, which dis-perses abort initiation altitude or time along with all other Launch Abort System (LAS) parameters during Monte Carlo simulations. In contrast, the standard methodology assumes that an abort initiation condition is held constant (e.g., aborts initiated at altitude for Mach 1, altitude for maximum dynamic pressure, etc.) while dispersing other LAS parameters. The standard method results in large gaps in performance information due to the discrete nature of initiation conditions, while the full-envelope dispersion method provides a significantly more comprehensive assessment of LAS abort performance for the full launch vehicle ascent flight envelope and identifies performance "pinch-points" that may occur at flight conditions outside of those contained in the discrete set. The new method has significantly increased the fidelity of LAS abort simulations and confidence in the results.

The Orion Crew Exploration Vehicle is America s next generation of human rated spacecraft. The Orion Launch Abort System will take the astronauts away from the exploration vehicle in the event of an aborted launch. The pad abort mode of the Launch Abort System will be flight-tested in 2009 from the White Sands Missile Range in New Mexico. This paper examines some of the efforts currently underway at the NASA Dryden Flight Research Center by the Controls & Dynamics group in preparation for the flight test. The concept of operation for the pad abort flight is presented along with an overview of the guidance, control and navigation systems. Preparations for the flight test, such as hardware testing and development of the real-time displays, are examined. The results from the validation and verification efforts for the aerodynamic and atmospheric models are shown along with Monte Carlo analysis results.

The Constellation program is an organization within NASA whose mission is to create the new generation of spacecraft that will replace the Space Shuttle after its planned retirement in 2010. In the event of a catastrophic failure on the launch pad or launch vehicle during ascent, the successful use of the launch abort system will allow crew members to escape harm. The Flight Test Office is the organization within the Constellation project that will flight-test the launch abort system on the Orion crew exploration vehicle. The Flight Test Office has proposed six tests that will demonstrate the use of the launch abort system. These flight tests will be performed at the White Sands Missile Range in New Mexico and are similar in nature to the Apollo Little Joe II tests performed in the 1960s. An overview of the launch abort system flight tests for the Orion crew exploration vehicle is given. Details on the configuration of the first pad abort flight test are discussed. Sample flight trajectories for two of the six flight tests are shown.
Ascent abort capability for the HL-20

The HL-20 has been designed with the capability for rescue of the crew during all phases of powered ascent from on the launch pad until orbital injection. A launch-escape system, consisting of solid rocket motors located on the adapter between the HL-20 and the launch vehicle, provides the thrust that propels the HL-20 to a safe distance from a malfunctioning launch vehicle. After these launch-escape motors have burned out, the adapter is jettisoned and the HL-20 executes one of four abort modes. In three abort modes - return-to-launch-site, transatlantic-abort-landing, and abort-to-orbit - not only is the crew rescued, but the HL-20 is recovered intact. In the ocean-landing-by-parachute abort mode, which occurs in between the return-to-launch-site and the transatlantic-abort-landing modes, the crew is rescued, but the HL-20 would likely sustain damage from the ocean landing. This paper describes the launch-escape system and the four abort modes for an ascent on a Titan III launch vehicle.

Although Colombia partially liberalized its abortion law in 2006, many abortions continue to occur outside the law and result in complications. Assessing the costs to the health care system of safe, legal abortions and of treating complications of unsafe, illegal abortions has important policy implications. The Post-Abortion Care Costing Methodology was used to produce estimates of direct and indirect costs of postabortion care and direct costs of legal abortions in Colombia. Data on estimated costs were obtained through structured interviews with key informants at a randomly selected sample of facilities that provide abortion-related care, including 25 public and private secondary and tertiary facilities and five primary-level private facilities that provide specialized reproductive health services. The median direct cost of treating a woman with abortion complications ranged from $44 to $141 (in U.S. dollars), representing an annual direct cost to the health system of about $14 million per year. A legal abortion at a secondary or tertiary facility was costly (medians, $213 and $189, respectively), in part because of the use of dilation and curettage, as well as because of administrative barriers. At specialized facilities, where manual vacuum aspiration and medication abortion are used, the median cost of provision was much lower ($45). Provision of postabortion care and legal abortion services at higher-level facilities results in unnecessarily high health care costs. These costs can be reduced significantly by providing services in a timely fashion at primary-level facilities and by using safe, noninvasive and less costly abortion methods.
Optimal Mission Abort Policy for Systems Operating in a Random Environment.

Levitin, Gregory; Finkelstein, Maxim

Many real-world critical systems, e.g., aircrafts, manned space flight systems, and submarines, utilize mission aborts to enhance their survivability. Specifically, a mission can be aborted when a certain malfunction condition is met and a rescue or recovery procedure is then initiated. For systems exposed to external impacts, the malfunctions are often caused by the consequences of these impacts. Traditional system reliability models typically cannot address a possibility of mission aborts. Therefore, in this article, we first develop the corresponding methodology for modeling and evaluation of the mission success probability and survivability of systems experiencing both internal failures and external shocks. We consider a policy when a mission is aborted and a rescue procedure is activated upon occurrence of the mth shock. We demonstrate the tradeoff between the system survivability and the mission success probability that should be balanced by the proper choice of the decision variable m. A detailed illustrative example of a mission performed by an unmanned aerial vehicle is presented. © 2017 Society for Risk Analysis.

Unsafe abortion is a significant but preventable cause of maternal mortality. Although induced abortion has been legal in Zambia since 1972, many women still face logistical, financial, social, and legal obstacles to access safe abortion services, and undergo unsafe abortion instead. This study provides the first estimates of costs of post abortion care (PAC) after an unsafe abortion and the cost of safe abortion in Zambia. In the absence of routinely collected data on abortions, we used multiple data sources: key informant interviews, medical records and hospital logbooks. We estimated the costs of providing safe abortion and PAC services at the University Teaching Hospital, Lusaka and then projected these costs to generate indicative cost estimates for Zambia. Due to unavailability of data on the actual number of safe abortions and PAC cases in Zambia, we used estimates from previous studies and from other similar countries, and checked the robustness of our estimates with sensitivity analyses. We found that PAC following an unsafe abortion can cost 2.5 times more than safe abortion care. The Zambian health system could save as much as US$0.4 million annually if those women currently treated for an unsafe abortion instead had a safe abortion.

The theory of System Health Management (SHM) and of its operational subset Fault Management (FM) states that FM is implemented as a "meta" control loop, known as an FM Control Loop (FMCL). The FMCL detects that all or part of a system is now failed, or in the future will fail (that is, cannot be controlled within acceptable limits to achieve its objectives), and takes a control action (a response) to return the system to a controllable state. In terms of control theory, the effectiveness of each FMCL is estimated based on its ability to correctly estimate the system state, and on the speed of its response to the current or impending failure effects. This paper describes how this theory has been successfully applied on the National Aeronautics and Space Administration's (NASA) Space Launch System (SLS) Program to quantitatively estimate the effectiveness of proposed abort triggers so as to select the most effective suite to protect the astronauts from catastrophic failure of the SLS. The premise behind this process is to be able to quantitatively provide the value versus risk trade-off for any given abort trigger, allowing decision makers to make more informed decisions. All current and planned crewed launch vehicles have some form of vehicle health management system integrated with an emergency launch abort system to ensure crew safety. While the design can vary, the underlying principle is the same: detect imminent catastrophic vehicle failure, initiate launch abort, and extract the crew to safety. Abort triggers are the detection mechanisms that identify that a catastrophic launch vehicle failure is occurring or is imminent and cause the initiation of a notification to the crew vehicle that the escape system must be activated. While ensuring that the abort triggers provide this function, designers must also ensure that the abort triggers do not signal that a catastrophic failure is imminent when in fact the launch vehicle can successfully achieve orbit. That is, the abort triggers must have low false negative rates to be sure that real crew-threatening failures are detected, and also low false positive rates to ensure that the crew does not abort from non-crew-threatening launch vehicle behaviors. The analysis process described in this paper is a compilation of over six years of lessons learned and refinements from experiences developing abort triggers for NASA's Constellation Program (Ares I Project) and the SLS Program, as well as the simultaneous development of SHM/FM theory. The paper will describe the abort analysis concepts and process, developed in conjunction with SLS Safety and Mission Assurance (S&MA) to define a common set of mission phase, failure scenario, and Loss of Mission Environment (LOME) combinations upon which the SLS Loss of Mission (LOM) Probabilistic Risk Assessment (PRA) models are built. This abort analysis also requires strong coordination with the Multi-Purpose Crew Vehicle (MPCV) and SLS Structures and Environments (STE) to formulate a series of abortability tables that encapsulate explosion dynamics over the ascent mission phase. The design and assessment of abort conditions and triggers to estimate their Loss of Crew (LOC) Benefits also requires in-depth integration with other groups, including Avionics, Guidance, Navigation and Control(GN&C), the Crew Office, Mission Operations, and Ground Systems. The outputs of this analysis are a critical input to SLS S&MA's LOC PRA models. The process described here may well be the first full quantitative application of SHM/FM theory to the selection of a sensor suite for any aerospace system.

The NASA Orion Flight Test Office was tasked with conducting a series of flight tests in several launch abort scenarios to certify that the Orion Launch Abort System is capable of delivering astronauts aboard the Orion Crew Module to a safe environment, away from a failed booster. The first of this series was the Orion Pad Abort 1 Flight-Test Vehicle, which was successfully flown on May 6, 2010 at the White Sands Missile Range in New Mexico. This paper provides a brief overview of the three propulsive subsystems used on the Pad Abort 1 Flight-Test Vehicle. An overview of the propulsive systems originally planned for future flight-test vehicles is also provided, which also includes the cold gas Reaction Control System within the Crew Module, and the Peacekeeper first stage rocket motor encased within the Abort Test Booster aeroshell. Although the Constellation program has been cancelled and the operational role of the Orion spacecraft has significantly evolved, lessons learned from Pad Abort 1 and the other flight-test vehicles could certainly contribute to the vehicle architecture of many future human-rated space launch vehicles.

Implementation of legal abortion in Nepal: a model for rapid scale-up of high-quality care

PubMed Central

2012-01-01

Unsafe abortion's significant contribution to maternal mortality and morbidity was a critical factor leading to liberalization of Nepal's restrictive abortion law in 2002. Careful, comprehensive planning among a range of multisectoral stakeholders, led by Nepal's Ministry of Health and Population, enabled the country subsequently to introduce and scale up safe abortion services in a remarkably short timeframe. This paper examines factors that contributed to rapid, successful implementation of legal abortion in this mountainous republic, including deliberate attention to the key areas of policy, health system capacity, equipment and supplies, and information dissemination. Important elements of this successful model of scaling up safe legal abortion include: the pre-existence of postabortion care services, through which health-care providers were already familiar with the main clinical technique for safe abortion; government leadership in coordinating complementary contributions from a wide range of public- and private-sector actors; reliance on public-health evidence in formulating policies governing abortion provision, which led to the embrace of medical abortion and authorization of midlevel providers as key strategies for decentralizing care; and integration of abortion care into existing Safe Motherhood and the broader health system. While challenges remain in ensuring that all Nepali women can readily exercise their legal right to early pregnancy termination, the national safe abortion program has already yielded strong positive results. Nepal's experience making high-quality abortion care widely accessible in a short period of time offers important lessons for other countries seeking to reduce maternal mortality and morbidity from unsafe abortion and to achieve Millennium Development Goals.

[Complications of induced abortion].

PubMed

Kretowicz, J

1984-03-26

The abortion problem has been a major topic of debate for many years. Polish legislation permitting abortion has both supporters and opponents. It appears that both groups fail to fully recognize the risks of the various medical complications of induced abortion. A literature review of the complications of abortion shows that these complications are often underestimated by the public and the medical community. The review clearly demonstrates that abortion adversely affects women's health. Inflammation of the genital system is the most frequent complication. The ocurrence of complications increases as the term of the pregnancy advances. It is concluded that the public is not fully aware of the immediate danger and aftereffects of induced abortion. Wider popularization of the extensive body of scientific information regarding the risks of induced abortion might change current perceptions about the "safety" of abortion.
The Affordable Care Act and Abortion Comparing the U.S. and Western Europe.

PubMed

McFarlane, Deborah R

2015-01-01

The 2010 Affordable Health Care Act (ACA) treats abortion differently than any other health service, precluding public funding for abortion and imposing other restrictions on American states. To determine whether the ACA's abortion restrictions are uniquely American or have counterparts in other national health systems, this study employs a cross-sectional design comparing abortion restrictions in the ACA with those in 17 Western European countries. Using a six-item scale, the intensity of abortion restrictions is compared across Western European nations. A similar scale is employed for a five-state sample of state-level abortion restrictions. Although the United States is not alone in having abortion restrictions, how abortion is proscribed in the ACA has no counterpart in Western Europe. Unlike many Western European countries, the ACA's restrictions focus on abortion funding, not the length of gestation or the health of the pregnant woman.

One of the primary design drivers for NASA's Crew Exploration Vehicle (CEV) is to ensure crew safety. Aborts during the critical ascent flight phase require the design and operation of CEV systems to escape from the Crew Launch Vehicle and return the crew safely to the Earth. To accomplish this requirement of continuous abort coverage, CEV ascent abort modes are being designed and analyzed to accommodate the velocity, altitude, atmospheric, and vehicle configuration changes that occur during ascent. The analysis involves an evaluation of the feasibility and survivability of each abort mode and an assessment of the abort mode coverage. These studies and design trades are being conducted so that more informed decisions can be made regarding the vehicle abort requirements, design, and operation. This paper presents an overview of the CEV, driving requirements for abort scenarios, and an overview of current ascent abort modes. Example analysis results are then discussed. Finally, future areas for abort analysis are addressed.

CAPE CANAVERAL, Fla. - The second set of two Ogive panels for the Orion Launch Abort System have arrived at the Launch Abort System Facility, or LASF, at NASA’s Kennedy Space Center in Florida. One of the Ogive panels has been uncrated and is being moved by crane for placement on a work stand. The launch abort system is positioned on a work stand. During processing, the panels will be secured around the Orion crew module and attached to the Launch Abort System. Orion is the exploration spacecraft designed to carry astronauts to destinations not yet explored by humans, including an asteroid and Mars. It will have emergency abort capability, sustain the crew during space travel and provide safe re-entry from deep space return velocities. The first unpiloted test flight of Orion is scheduled to launch in 2014 atop a Delta IV rocket and in 2017 on NASA’s Space Launch System rocket. For more information, visit www.nasa.gov/orion.

Reducing abortion-related mortality in South Asia: a review of constraints and a road map for change.

Ganatra, Bela; Johnston, Heidi Bart

2002-01-01

South Asia (Bangladesh, India, Nepal, Pakistan, and Sri Lanka) is home to 28% of the world's people and accounts for about a third (30%) of the world's maternal deaths. Thirteen percent of all maternal deaths in South Asia are attributed to complications of unsafe abortion and are almost entirely preventable. This article reviews the legal, health system, and sociocultural barriers to safe abortion and suggests strategies to reduce abortion-related morbidity and mortality. Restrictive laws hamper safe abortion in most of the region, but even where laws are more liberal, limited awareness of the law has been a barrier to access. Such health system barriers as an insufficient number of trained providers, inequitable distribution of services, and excessive costs have contributed to death from unsafe abortion. Sociocultural attitudes, including the right of male relatives to make reproductive decisions, the emphasis on male heirs, and the strong social stigma against extramarital pregnancy also put women at risk. Government and other institutions must strive to prevent abortion-related death and disability by making safe abortion services accessible to the fullest extent of the law. Health systems need to provide emergency care for complications and postabortion contraceptive counseling, use appropriate technology, and allow nonphysician providers to deliver care. Safe abortion care programs need to address the needs of the local community, particularly the needs of socially and economically vulnerable subgroups, such as the unmarried and adolescents.

Abortion rights down under.

State and federal governments in Australia fear actively trying to ensure access to abortion. No federal abortion law in Australia exists. Abortion is a state matter. The federal government's health care system does reimburse women for abortion services, however. State laws prohibit unlawful abortions but they do not define what they mean by unlawful abortion. Victoria, New South Wales, and Queensland have had common law interpretations of their Crimes Acts, which allow greater access to abortion. Tasmania and Western Australia have not had common law interpretations. Thus, even though abortion is available, women and providers are not secure. Abortion reform in South Australia and the Northern Territory has made access to abortion more difficult. A woman must be a resident in South Australia for 2 months before she can obtain an abortion. Abortions are allowed only in a clinic or a hospital. Women in metropolitan Melbourne and Sydney have good access to abortion services, while those in the country or in an isolated part of NSW or Victoria may have an antiabortion physician serving their area. Women in Queensland, Tasmania, and Western Australia pay a lot for an abortion because they also have to pay for airfare to a large city. Only a gynecologist can perform abortions in the Northern Territory. Social workers often coerce Aboriginal women into an abortion. The few antiabortion physicians have a big impact on whether women receive abortion information or not. Research at Adelaide and Flinders Universities show that abortion-related trauma is linked to obtaining information and access to abortion services. Physicians are nervous about performing abortions because abortion is still in the Crimes Acts and Criminal Codes, making it difficult to recruit high quality and empathetic practitioners. Antiabortion groups are small and tend not to adopt extreme tactics. The Abortion Rights Network of Australia has recently been formed.
Accounting for abortion: Accomplishing transnational reproductive governance through post-abortion care in Senegal.

PubMed

Suh, Siri

2018-06-01

Reproductive governance operates through calculating demographic statistics that offer selective truths about reproductive practices, bodies, and subjectivities. Post-abortion care, a global reproductive health intervention, represents a transnational reproductive regime that establishes motherhood as women's primary legitimate reproductive status. Drawing on ethnographic fieldwork conducted in Senegal between 2010 and 2011, I illustrate how post-abortion care accomplishes reproductive governance in a context where abortion is prohibited altogether and the US is the primary bilateral donor of population aid. Reproductive governance unfolds in hospital gynecological wards and the national health information system through the mobilization and interpretation of post-abortion care data. Although health workers search women's bodies and behavior for signs of illegal abortion, they minimize police intervention in the hospital by classifying most post-abortion care cases as miscarriage. Health authorities deploy this account of post-abortion care to align the intervention with national and global maternal health policies that valorize motherhood. Although post-abortion care offers life-saving care to women with complications of illegal abortion, it institutionalizes abortion stigma by scrutinizing women's bodies and masking induced abortion within and beyond the hospital. Post-abortion care reinforces reproductive inequities by withholding safe, affordable obstetric care from women until after they have resorted to unsafe abortion.
Orion Launch Abort System (LAS) Propulsion on Pad Abort 1 (PA-1)

Jones, Daniel S.

2015-01-01

This presentation provides a concise overview of the highly successful Orion Pad Abort 1 (PA-1) flight test, and the three rocket motors that contributed to this success. The primary purpose of the Orion PA-1 flight was to help certify the Orion Launch Abort System (LAS), which can be utilized in the unlikely event of an emergency on the launchpad or during mission vehicle ascent. The PA-1 test was the first fully integrated flight test of the Orion LAS, one of the primary systems within the Orion Multi-Purpose Crew Vehicle (MPCV). The Orion MPCV is part of the architecture within the Space Launch System (SLS), which is being designed to transport astronauts beyond low-Earth orbit for future exploration missions. Had the Orion PA-1 flight abort occurred during launch preparations for a real human spaceflight mission, the PA-1 LAS would have saved the lives of the crew. The PA-1 flight test was largely successful due to the three solid rocket motors of the LAS: the Attitude Control Motor (ACM); the Jettison Motor (JM); and the Abort Motor (AM). All three rocket motors successfully performed their required functions during the Orion PA-1 flight test, flown on May 6, 2010 at the White Sands Missile Range in New Mexico, culminating in a successful demonstration of an abort capability from the launchpad.
Safe abortion: WHO technical and policy guidance.

In 2003, the World Health Organization published its well referenced handbook Safe Abortion: Technical and Policy Guidance for Health Systems to address the estimated almost 20 million induced abortions each year that are unsafe, imposing a burden of approximately 67 thousand deaths annually. It is a global injustice that 95% of unsafe abortions occur in developing countries. The focus of guidance is on abortion procedures that are lawful within the countries in which they occur, noting that in almost all countries, the law permits abortion to save a woman's life. The guidance treats unsafe abortion as a public health challenge, and responds to the problem through strategies concerning improved clinical care for women undergoing procedures, and the appropriate placement of necessary services. Legal and policy considerations are explored, and annexes present guidance to further reading, international consensus documents on safe abortion, and on manual vacuum aspiration and post-abortion contraception.

The first flight test of the Orion Abort Flight Test project is scheduled to launch in Spring 2010. This flight test is known as Pad Abort 1 (PA-1) and it is intended to accomplish a series of flight test objectives, including demonstrating the capability of the Launch Abort System (LAS) to propel the Crew Module (CM) to a safe distance from a launch vehicle during a pad abort. The PA-1 Flight Test Article (FTA) is actively controlled by a guidance, navigation, and control (GN&C) system for much of its flight. The purpose of this paper is to describe the design, development, and analysis of the PA-1 GN&C system. A description of the technical solutions that were developed to meet the challenge of satisfying many competing requirements is presented. A historical perspective of how the Orion LAV compares to the Apollo Launch Escape Vehicle (LEV) design will also be included.

With changing patterns and increasing use of medical abortion in the United States, it is important to have accurate statistics on the use of this method regularly available. This study assesses the accuracy of medical abortion data reported annually to the Centers for Disease Control and Prevention (CDC) and describes trends over time in the use of medical abortion relative to other methods. This analysis included data reported to CDC for 2001-2008. Year-specific analyses included all states that monitored medical abortion for a given year, while trend analyses were restricted to states that monitored medical abortion continuously from 2001 to 2008. Data quality and completeness were assessed by (a) examining abortions reported with an unspecified method type within the gestational age limit for medical abortion (med-eligible abortions) and (b) comparing the percentage of all abortions and med-eligible abortions reported to CDC as medical abortions with estimates based on published mifepristone sales data for the United States from 2001 to 2007. During 2001-2008, the percentage of med-eligible abortions reported to CDC with an unspecified method type remained low (1.0%-2.2%); CDC data and mifepristone sales estimates for 2001-2007 demonstrated strong agreement [all abortions: intraclass correlation coefficient (ICC)=0.983; med-eligible abortions: ICC=0.988]. During 2001-2008, the percentage of abortions reported to CDC as medical abortions increased (p<.001 for all abortions and for med-eligible abortions). Among states that reported medical abortions for 2008, 15% of all abortions and 23% of med-eligible abortions were reported as medical abortions. CDC's Abortion Surveillance System provides an important annual data source that accurately describes the use of medical abortion relative to other methods in the United States.

RB-ARD: A proof of concept rule-based abort

The Abort Region Determinator (ARD) is a console program in the space shuttle mission control center. During shuttle ascent, the Flight Dynamics Officer (FDO) uses the ARD to determine the possible abort modes and make abort calls for the crew. The goal of the Rule-based Abort region Determinator (RB/ARD) project was to test the concept of providing an onboard ARD for the shuttle or an automated ARD for the mission control center (MCC). A proof of concept rule-based system was developed on a LMI Lambda computer using PICON, a knowdedge-based system shell. Knowdedge derived from documented flight rules and ARD operation procedures was coded in PICON rules. These rules, in conjunction with modules of conventional code, enable the RB-ARD to carry out key parts of the ARD task. Current capabilities of the RB-ARD include: continuous updating of the available abort mode, recognition of a limited number of main engine faults and recommendation of safing actions. Safing actions recommended by the RB-ARD concern the Space Shuttle Main Engine (SSME) limit shutdown system and powerdown of the SSME Ac buses.
A simulation model for probabilistic analysis of Space Shuttle abort modes

Hage, R. T.

1993-01-01

A simulation model which was developed to provide a probabilistic analysis tool to study the various space transportation system abort mode situations is presented. The simulation model is based on Monte Carlo simulation of an event-tree diagram which accounts for events during the space transportation system's ascent and its abort modes. The simulation model considers just the propulsion elements of the shuttle system (i.e., external tank, main engines, and solid boosters). The model was developed to provide a better understanding of the probability of occurrence and successful completion of abort modes during the vehicle's ascent. The results of the simulation runs discussed are for demonstration purposes only, they are not official NASA probability estimates.

This article gives an overview of what is known about second trimester abortions in India, including the reasons why women seek abortions in the second trimester, the influence of abortion law and policy, surgical and medical methods used, both safe and unsafe, availability of services, requirements for second trimester service delivery, and barriers women experience in accessing second trimester services. Based on personal experiences and personal communications from other doctors since 1993, when I began working as an abortion provider, the practical realities of second trimester abortion and case histories of women seeking second trimester abortion are also described. Recommendations include expanding the cadre of service providers to non-allopathic clinicians and trained nurses, introducing second trimester medical abortion into the public health system, replacing ethacridine lactate with mifepristone-misoprostol, values clarification among providers to challenge stigma and poor treatment of women seeking second trimester abortion, and raising awareness that abortion is legal in the second trimester and is mostly not requested for reasons of sex selection.
Abortion and maternal mortality in the developing world.

PubMed

Okonofua, Friday

2006-11-01

Unsafe abortion is an important public health problem, accounting for 13% of maternal mortality in developing countries. Of an estimated annual 70,000 deaths from unsafe abortion worldwide, over 99% occur in the developing countries of sub-Saharan Africa, Central and Southeast Asia, and Latin America and the Caribbean. Factors associated with increased maternal mortality from unsafe abortion in developing countries include inadequate delivery systems for contraception needed to prevent unwanted pregnancies, restrictive abortion laws, pervading negative cultural and religious attitudes towards induced abortion, and poor health infrastructures for the management of abortion complications. The application of a public health approach based on primary, secondary, and tertiary prevention can reduce morbidity and mortality associated with unsafe abortion in developing countries. Primary prevention includes the promotion of increased use of contraception by women (and by men) at risk for unwanted pregnancy; secondary prevention involves the liberalization of abortion laws and the development of programs to increase access to safe abortion care in developing countries. In contrast, tertiary prevention includes the integration and institutionalization of post-abortion care for incomplete abortion and the early and appropriate treatment of more severe complications of abortion. Efforts to address these problems will contribute both to reducing maternal mortality associated with induced abortion and to achieving the Millennium Development Goals in developing countries.

The purpose of NASA's Constellation project is to create the new generation of spacecraft for human flight to the International Space Station in low-earth orbit, the lunar surface, as well as for use in future deep-space exploration. One portion of the Constellation program was the development of the Orion crew exploration vehicle (CEV) to be used in spaceflight. The Orion spacecraft consists of a crew module, service module, space adapter and launch abort system. The crew module was designed to hold as many as six crew members. The Orion crew exploration vehicle is similar in design to the Apollo space capsules, although larger and more massive. The Flight Test Office is the responsible flight test organization for the launch abort system on the Orion crew exploration vehicle. The Flight Test Office originally proposed six tests that would demonstrate the use of the launch abort system. These flight tests were to be performed at the White Sands Missile Range in New Mexico and were similar in nature to the Apollo Little Joe II tests performed in the 1960s. The first flight test of the launch abort system was a pad abort (PA-1), that took place on 6 May 2010 at the White Sands Missile Range in New Mexico. Primary flight test objectives were to demonstrate the capability of the launch abort system to propel the crew module a safe distance away from a launch vehicle during a pad abort, to demonstrate the stability and control characteristics of the vehicle, and to determine the performance of the motors contained within the launch abort system. The focus of the PA-1 flight test was engineering development and data acquisition, not certification. In this presentation, a high level overview of the PA-1 vehicle is given, along with an overview of the Mobile Operations Facility and information on the White Sands tracking sites for radar & optics. Several lessons learned are presented, including detailed information on the lessons learned in the development of wind placards for flight. PA-1 flight data is shown, as well as a comparison of PA-1 flight data to nonlinear simulation Monte Carlo data.
Launch Vehicle Abort Analysis for Failures Leading to Loss of Control

Hanson, John M.; Hill, Ashley D.; Beard, Bernard B.

2013-01-01

Launch vehicle ascent is a time of high risk for an onboard crew. There is a large fraction of possible failures for which time is of the essence and a successful abort is possible if the detection and action happens quickly enough. This paper focuses on abort determination based on data already available from the Guidance, Navigation, and Control system. This work is the result of failure analysis efforts performed during the Ares I launch vehicle development program. The two primary areas of focus are the derivation of abort triggers to ensure that abort occurs as quickly as possible when needed, but that false aborts are avoided, and evaluation of success in aborting off the failing launch vehicle.
Abortion in Iranian legal system: a review.

Abortion traditionally means, "to miscarry" and is still known as a problem which societies has been trying to reduce its rate by using legal means. Despite the pregnant women and fetuses have being historically supported; abortion was firstly criminalized in 1926 in Iran, 20 years after establishment of modern legal system. During next 53 years this situation changed dramatically, so in 1979, the time of Islamic Revolution, aborting fetuses before 12 weeks and therapeutic abortion (TA) during all the pregnancy length was legitimate, based on regulations that used medical justification. After 1979 the situation changed into a totally conservative and restrictive approach and new Islamic concepts as "Blood Money" and "Ensoulment" entered the legal debates around abortion. During the next 33 years, again a trend of decriminalization for the act of abortion has been continuing. Reduction of punishments and omitting retaliation for criminal abortions, recognizing fetal and maternal medical indications including some immunologic problems as legitimate reasons for aborting fetuses before 4 months and omitting the fathers' consent as a necessary condition for TA are among these changes. The start point for this decriminalization process was public and professional need, which was responded by religious government, firstly by issuing juristic rulings (Fatwas) as a non-official way, followed by ratification of "Therapeutic Abortion Act" (TAA) and other regulations as an official pathway. Here, we have reviewed this trend of decriminalization, the role of public and professional request in initiating such process and the rule-based language of TAA.

Despite the implementation of prospective payment approach in France, induced legal abortion are still paid by capitation. Our aim was to evaluate the real cost of induced abortion in a public hospital in France. This study took place during the year 2008 in a public health hospital. Induced abortion cost was calculated according to national study cost's recommendations. The cost drawn from this was compared to what is paid by the medical insurance for spontaneous abortion. Induced abortion calculated cost was 562 €, the capitation amount was 286.86 €, the spontaneous abortion compensation amount was 645 €. Induced abortion should be paid by a prospective payment evaluation similar to diagnosis related groups approaches rather than a capitation payment, in order to reduce misstatements.

Dynamic Modeling of Ascent Abort Scenarios for Crewed Launches

NASA Technical Reports Server (NTRS)

Bigler, Mark; Boyer, Roger L.

2015-01-01

For the last 30 years, the United States's human space program has been focused on low Earth orbit exploration and operations with the Space Shuttle and International Space Station programs. After nearly 50 years, the U.S. is again working to return humans beyond Earth orbit. To do so, NASA is developing a new launch vehicle and spacecraft to provide this capability. The launch vehicle is referred to as the Space Launch System (SLS) and the spacecraft is called Orion. The new launch system is being developed with an abort system that will enable the crew to escape launch failures that would otherwise be catastrophic as well as probabilistic design requirements set for probability of loss of crew (LOC) and loss of mission (LOM). In order to optimize the risk associated with designing this new launch system, as well as verifying the associated requirements, NASA has developed a comprehensive Probabilistic Risk Assessment (PRA) of the integrated ascent phase of the mission that includes the launch vehicle, spacecraft and ground launch facilities. Given the dynamic nature of rocket launches and the potential for things to go wrong, developing a PRA to assess the risk can be a very challenging effort. Prior to launch and after the crew has boarded the spacecraft, the risk exposure time can be on the order of three hours. During this time, events may initiate from either of the spacecraft, the launch vehicle, or the ground systems, thus requiring an emergency egress from the spacecraft to a safe ground location or a pad abort via the spacecraft's launch abort system. Following launch, again either the spacecraft or the launch vehicle can initiate the need for the crew to abort the mission and return to the home. Obviously, there are thousands of scenarios whose outcome depends on when the abort is initiated during ascent as to how the abort is performed. This includes modeling the risk associated with explosions and benign system failures that require aborting a spacecraft under very dynamic conditions, particularly in the lower atmosphere, and returning the crew home safely. This paper will provide an overview of the PRA model that has been developed of this new launch system, including some of the challenges that are associated with this effort.

The public funding of abortion in Canada: going beyond the concept of medical necessity.

PubMed

Kaposy, Chris

2009-08-01

This article defends the public funding of abortion in the Canadian health care system in light of objections by opponents of abortion that the procedure should be denied public funding. Abortion opponents point out that women terminate their pregnancies most often for social reasons, that the Canadian health care system only requires funding for medically necessary procedures, and that abortion for social reasons is not medically necessary care. I offer two lines of response. First, I briefly present an argument that characterizes abortion sought for social reasons as medically necessary care, directly contesting the anti-abortion position. Second, and more substantially, I present a justice argument that shows that even if abortion is not regarded as medically necessary care, the reasons that typically motivate women to seek abortion are sufficiently weighty from the moral perspective that it would be unjust to deny them public funding. I finish by drawing the more general conclusion that health care funding decisions should be guided by a broader concept of necessary care, rather than by a narrow concept of specifically medical necessity. A broad concept of necessary care has been debated in health care policy in the Netherlands, and I suggest that such a concept would be a more just and defensible guide for funding decisions than the concept of medical necessity.
Death after legally induced abortion. A comprehensive approach for determination of abortion-related deaths based on record linkage.

PubMed Central

Shelton, J D; Schoenbucher, A K

1978-01-01

The sources for determination of abortion-related deaths in Georgia are the cause of death listed on the death certificate and reports from informal reporting channels. Although Georgia residents 10-44 years of age obtained 19,877 induced abortions in 1975, no deaths related to abortion were found through these two usual sources. To determine the sensitivity of this system, all abortion certificates for 1975 were compared with all death certificates of Georgia females aged 10-44 who died in 1975 and the first 2 months of 1976. Based on the age and racial distribution of the women who received abortions, approximately 13 deaths (from all causes) would be expected to have subsequently occurred during the period of time studied. The authors found only 10. From national death-to-case rates for legal abortion, the expected number actually atrributable to abortion was 0.78 death. Of the 10 deaths, 2 were potentially related to the previous abortion, but a causal relationship to the preceding abortion was not clearly evident for any of the 10 deaths. The data, therefore, tend to support the assertion that no large numbers of deaths related to abortion are undiscovered and that current measurements of abortion mortality are accurate.

An optimal cut-off point for the calving interval may be used as an indicator of bovine abortions.

The bovine abortion surveillance system in France aims to detect as early as possible any resurgence of bovine brucellosis, a disease of which the country has been declared free since 2005. It relies on the mandatory notification and testing of each aborting cow, but under-reporting is high. This research uses a new and simple approach which considers the calving interval (CI) as a "diagnostic test" to determine optimal cut-off point c and estimate diagnostic performance of the CI to identify aborting cows, and herds with multiple abortions (i.e. three or more aborting cows per calving season). The period between two artificial inseminations (AI) was considered as a "gold standard". During the 2006-2010 calving seasons, the mean optimal CI cut-off point for identifying aborting cows was 691 days for dairy cows and 703 days for beef cows. Depending on the calving season, production type and scale at which c was computed (individual or herd), the average sensitivity of the CI varied from 42.6% to 64.4%; its average specificity from 96.7% to 99.7%; its average positive predictive value from 27.6% to 65.4%; and its average negative predictive value from 98.7% to 99.8%. When applied to the French bovine population as a whole, this indicator identified 2-3% of cows suspected to have aborted, and 10-15% of herds suspected of multiple abortions. The optimal cut-off point and CI performance were consistent over calving seasons. By applying an optimal CI cut-off point to the cattle demographics database, it becomes possible to identify herds with multiple abortions, carry out retrospective investigations to find the cause of these abortions and monitor a posteriori compliance of farmers with their obligation to report abortions for brucellosis surveillance needs. Therefore, the CI could be used as an indicator of abortions to help improve the current mandatory notification surveillance system. Copyright © 2015 Elsevier B.V. All rights reserved.
Modeling, Analysis and Simulation Approaches Used in Development of the National Aeronautics and Space Administration Max Launch Abort System

Yuchnovicz, Daniel E.; Dennehy, Cornelius J.; Schuster, David M.

2011-01-01

The National Aeronautics and Space Administration (NASA) Engineering and Safety Center was chartered to develop an alternate launch abort system (LAS) as risk mitigation for the Orion Project. Its successful flight test provided data for the design of future LAS vehicles. Design of the flight test vehicle (FTV) and pad abort trajectory relied heavily on modeling and simulation including computational fluid dynamics for vehicle aero modeling, 6-degree-of-freedom kinematics models for flight trajectory modeling, and 3-degree-of-freedom kinematics models for parachute force modeling. This paper highlights the simulation techniques and the interaction between the aerodynamics, flight mechanics, and aerodynamic decelerator disciplines during development of the Max Launch Abort System FTV.

Health services fail women who suffer unsafe abortion.

PubMed

1994-02-01

Physicians, medical schools, and health systems are failing, respectively, to provide the treatment, training, and facilities necessary for proper care of women suffering from the complications of unsafe abortions. Family planning services, also, are failing to reach the women at risk. Thousands of women are dying because of this. In some countries, unsafe abortions may account for as many as half of maternal deaths; however, due to social attitudes, information is hard to obtain. The report of the World Health Organization Technical Working Group on the Prevention and Management of Unsafe Abortion has been released. This report states that treatment of these complications should be extended throughout the health care system; more training and facilities, especially at the primary care level, are necessary; physicians should give higher priority to complications due to unsafe abortions; "punitive attitudes" or health care workers should not effect treatment; more research on the management of complications of unsafe abortions and on the use of contraception after abortion is necessary; family planning advice and assistance should be offered after treatment for complications; and family planning services should be designed with women's preferences in mind. The report also lists tests, treatments, and services necessary at primary care and first referral levels for women with complications from unsafe abortions.

Background Rural induced abortion service has declined in Canada. Factors influencing abortion provision by rural physicians are unknown. This study assessed distribution, practice, and experiences among rural compared to urban abortion providers in the Canadian province of British Columbia (BC). Methods We used mixed methods to assess physicians on the BC registry of abortion providers. In 2011 we distributed a previously-published questionnaire and conducted semi-structured interviews. Results Surveys were returned by 39/46 (85%) of BC abortion providers. Half were family physicians, within both rural and urban cohorts. One-quarter (17/67) of rural hospitals offer abortion service. Medical abortions comprised 14.7% of total reported abortions. The three largest urban areas reported 90% of all abortions, although only 57% of reproductive age women reside in the associated health authority regions. Each rural physician provided on average 76 (SD 52) abortions annually, including 35 (SD 30) medical abortions. Rural physicians provided surgical abortions in operating rooms, often using general anaesthesia, while urban physicians provided the same services primarily in ambulatory settings using local anaesthesia. Rural providers reported health system barriers, particularly relating to operating room logistics. Urban providers reported occasional anonymous harassment and violence. Conclusions Medical abortions represented 15% of all BC abortions, a larger proportion than previously reported (under 4%) for Canada. Rural physicians describe addressable barriers to service provision that may explain the declining accessibility of rural abortion services. Moving rural surgical abortions out of operating rooms and into local ambulatory care settings has the potential to improve care and costs, while reducing logistical challenges facing rural physicians.

Unsafe and illegal abortions are the third leading cause of maternal death. It affects physical, emotional and social health of women and their families. Abortion is a multi-dimensional phenomenon with several social, legal, and religious implications. The views of policy-makers affect the approach to abortion in every society. Understanding the attitudes and knowledge of high-ranking decision makers towards abortion was the purpose of this study. A qualitative research was implemented by carrying out individual interviews with 29 out of a selection of 80 presidents of medical sciences universities, senior executive managers in the legal system, forensic medicine and decision-makers in the health system and a number of top Muslim clerics, using a semi-structured questionnaire for data gathering. Content analysis revealed the results. There were considerable unwillingness and reluctance among the interviewees to participate in the study. The majority of participants fairly knew about the prevalence of illegal abortions and their complications. There was strong agreement on abortion when health of the mother or the fetus was at risk. Abortion for reproductive health reasons was supported by a minority of the respondents. The majority of them disagreed with abortion when pregnancy was the result of a rape, temporary marriage or out of wedlock affairs. Making decision for abortion by the pregnant mother, as a matter of her right, did not gain too much approval. It seemed that physical health of the mother or the fetus was of more importance to the respondents than their mental or social health. The mother's hardship was not any indication for induced abortion in the viewpoints of the interviewed policy-makers. Strengthening family planning programs, making appropriate laws in lines with religious orders and advocacy programs targeting decision makers are determined as strategies for improving women's health rights.
Spontaneous abortion is associated with elevated systemic C5a and reduced mRNA of complement inhibitory proteins in placenta

Spontaneous abortion in early pregnancy due to unknown reasons is a common problem. The excess complement activation and consequent placental inflammation and anti-angiogenic milieu is emerging as an important associated factor in many pregnancy-related complications. In the present study we sought to examine the expression of complement inhibitory proteins at the feto–maternal interface and levels of complement split products in the circulation to understand their role in spontaneous abortion. Consenting pregnant women who either underwent elective abortion due to non-clinical reasons (n = 13) or suffered miscarriage (n = 14) were recruited for the study. Systemic levels of complement factors C3a and C5a were measured by enzyme-linked immunosorbent assay (ELISA). Plasma C5 and C3 protein levels were examined by Western blot. Expressions of complement regulatory proteins such as CD46 and CD55 in the decidua were investigated by quantitative polymerase chain reaction (PCR) and Western blot. The median of plasma C3a level was 82·83 ng/ml and 66·17 ng/ml in elective and spontaneous abortion patients, respectively. Medians of plasma C5a levels in elective and spontaneous abortion patients were 0·96 ng/ml and 1·14 ng/ml, respectively. Only plasma C5a levels but not C3a levels showed significant elevation in spontaneous abortion patients compared to elective abortion patients. Further, there was a threefold decrease in the mRNA expressions of complement inhibitory proteins CD46 and CD55 in the decidua obtained from spontaneous abortion patients compared to that of elective abortion patients. These data suggested that dysregulated complement cascade may be associated with spontaneous abortion. PMID:24802103
Velocity Requirements for Abort From the Boost Trajectory of a Manned Lunar Mission

NASA Technical Reports Server (NTRS)

Slye, Robert E.

1961-01-01

An investigation is made of the abort velocity requirements associated with failure of a propulsion system for a manned lunar mission. Two cases are considered: abort at less than satellite speed, which results in maximum decelerations in the following entry, and abort at greater than satellite speed with immediate return to earth. The velocity requirements associated with the latter problem are found to be substantial (several thousand feet per second) and are found to be even more severe if boost trajectories which lead to burnout at high altitudes or large flight-path angles are used. The velocity requirements associated with abort at less than satellite speed are found to be less severe than those for abort at greater than satellite speed except for nonlifting vehicles. It is found that abort rockets sufficient for abort at greater than satellite speed can be used to reduce maximum decelerations in entries following an abort at lower speeds. This reduction is accomplished by use of the abort rockets to decrease entry angle immediately prior to entry into the atmosphere.
Risk factors and the choice of long-acting reversible contraception following medical abortion: effect on subsequent induced abortion and unwanted pregnancy.

2018-04-01

To analyse the post-abortion effect of long-acting reversible contraception (LARC) plans and initiation on the risk of subsequent unwanted pregnancy and abortion. retrospective cohort study of 666 women who underwent medical abortion between January-May 2013 at Helsinki University Hospital, Finland. Altogether 159 (23.8%) women planning post-abortion use of levonorgestrel-releasing intrauterine system (LNG-IUS) participated in a randomized study and had an opportunity to receive the LNG-IUS free-of-charge from the hospital. The other 507 (76.2%) women planned and obtained their contraception according to clinical routine. Demographics, planned contraception, and LARC initiation at the time of the index abortion were collected. Data on subsequent abortions were retrieved from the Finnish Abortion Register and electronic patient files until the end of 2014. During the 21 months ([median], IQR 20-22) follow-up, 54(8.1%) women requested subsequent abortions. When adjusted for age, previous pregnancies, deliveries, induced abortions and gestational-age, planning LARC for post-abortion contraception failed to prevent subsequent abortion (33 abortions/360 women, 9.2%) compared to other contraceptive plans (21/306, 6.9%) (HR 1.22, 95% CI 0.68-2.17). However, verified LARC initiation decreased the abortion rate (4 abortions/177 women, 2.3%) compared to women with uncertain LARC initiation status (50/489, 10.2%) (HR 0.17, 95% CI 0.06-0.48). When adjusted for LARC initiation status, age <25 years was a risk factor for subsequent abortion (27 abortions/283 women, 9.5%) compared to women ≥25 years (27/383, 7.0%, HR1.95, 95% CI 1.04-3.67). Initiation of LARC as part of abortion service at the time of medical abortion is an important means to prevent subsequent abortion, especially among young women.

CAPE CANAVERAL, Fla. - The second set of two Ogive panels for the Orion Launch Abort System arrives by truck at the Launch Abort System Facility, or LASF, at NASA’s Kennedy Space Center in Florida. The Ogive panels will be uncrated inside the LASF. During processing, the panels will be secured around the Orion crew module and attached to the Launch Abort System. Orion is the exploration spacecraft designed to carry astronauts to destinations not yet explored by humans, including an asteroid and Mars. It will have emergency abort capability, sustain the crew during space travel and provide safe re-entry from deep space return velocities. The first unpiloted test flight of Orion is scheduled to launch in 2014 atop a Delta IV rocket and in 2017 on NASA’s Space Launch System rocket. For more information, visit www.nasa.gov/orion.

This paper will present an overview of the flight test objectives and performance of the Orion Launch Abort System during Exploration Flight Test-1. Exploration Flight Test-1, the first flight test of the Orion spacecraft, was managed and led by the Orion prime contractor, Lockheed Martin, and launched atop a United Launch Alliance Delta IV Heavy rocket. This flight test was a two-orbit, high-apogee, high-energy entry, low-inclination test mission used to validate and test systems critical to crew safety. This test included the first flight test of the Launch Abort System preforming Orion nominal flight mission critical objectives. NASA is currently designing and testing the Orion Multi-Purpose Crew Vehicle (MPCV). Orion will serve as NASA's new exploration vehicle to carry astronauts to deep space destinations and safely return them to earth. The Orion spacecraft is composed of four main elements: the Launch Abort System, the Crew Module, the Service Module, and the Spacecraft Adapter (Fig. 1). The Launch Abort System (LAS) provides two functions; during nominal launches, the LAS provides protection for the Crew Module from atmospheric loads and heating during first stage flight and during emergencies provides a reliable abort capability for aborts that occur within the atmosphere. The Orion Launch Abort System (LAS) consists of an Abort Motor to provide the abort separation from the Launch Vehicle, an Attitude Control Motor to provide attitude and rate control, and a Jettison Motor for crew module to LAS separation (Fig. 2). The jettison motor is used during a nominal launch to separate the LAS from the Launch Vehicle (LV) early in the flight of the second stage when it is no longer needed for aborts and at the end of an LAS abort sequence to enable deployment of the crew module's Landing Recovery System. The LAS also provides a Boost Protective Cover fairing that shields the crew module from debris and the aero-thermal environment during ascent. Although the Orion Program has tested a number of the critical systems of the Orion spacecraft on the ground, the launch environment cannot be replicated completely on Earth. A number of flight tests have been conducted and are planned to demonstrate the performance and enable certification of the Orion Spacecraft. Exploration Flight Test 1, the first flight test of the Orion spacecraft, was successfully flown on December 5, 2014 from Cape Canaveral Air Force Station's Space Launch Complex 37. Orion's first flight was a two-orbit, high-apogee, high-energy entry, low-inclination test mission used to validate and test systems critical to crew safety, such as heat shield performance, separation events, avionics and software performance, attitude control and guidance, parachute deployment and recovery operations. One of the key separation events tested during this flight was the nominal jettison of the LAS. Data from this flight will be used to verify the function of the jettison motor to separate the Launch Abort System from the crew module so it can continue on with the mission. The LAS nominal jettison event on Exploration Flight Test 1 occurred at six minutes and twenty seconds after liftoff (See Fig. 3). The abort motor and attitude control motors were inert for Exploration Flight Test 1, since the mission did not require abort capabilities. A suite of developmental flight instrumentation was included on the flight test to provide data on spacecraft subsystems and separation events. This paper will focus on the flight test objectives and performance of the LAS during ascent and nominal jettison. Selected LAS subsystem flight test data will be presented and discussed in the paper. Exploration Flight Test -1 will provide critical data that will enable engineering to improve Orion's design and reduce risk for the astronauts it will protect as NASA continues to move forward on its human journey to Mars. The lessons learned from Exploration Flight Test 1 and the other Flight Test Vehicles will certainly contribute to the vehicle architecture of a human-rated space launch vehicle.
International commitments and guidance on unsafe abortion.

Most of Africa's 54 countries have restrictive abortion laws, outdated remnants of former colonial laws that result in nearly five million unsafe abortions annually. To stem maternal mortality and morbidity, it is essential to look beyond strictly medical or health system approaches to solving this critical public health problem. The issue must be approached from a human rights perspective that emphasises the individual's right to self-determination. This article examines ways in which advocates can use established human rights standards, international consensus documents, and the World Health Organization's new technical and policy guidance for health systems to press for safer abortion care for African women.
Why do farmers and veterinarians not report all bovine abortions, as requested by the clinical brucellosis surveillance system in France?

PubMed Central

2014-01-01

Background Since 2005, France has been officially free of brucellosis, an infectious disease that causes abortion in cattle and can be transmitted from cattle to humans. Recent animal and human cases have drawn attention to the need to prevent infection of humans and animals from any primary outbreaks. In order to detect any new outbreaks as soon as possible, a clinical surveillance system requires farmers and veterinarians to report each abortion and to test the aborting cow for brucellosis. However, under-reporting limits the sensitivity of this system. Our objective was to identify the barriers and motivations influencing field actors in their decision to report or not to report bovine abortions. We used a qualitative approach with semi-structured interviews of 12 cattle farmers and their eight veterinarians. Results Our analysis showed that four main themes influence the decision-making process of farmers and veterinarians: 1) the perceived risk of brucellosis and other abortive diseases; 2) the definition of a suspected case of brucellosis and other abortive diseases adopted by field actors, which is less sensitive than the mandatory definition; 3) the cost-benefit analysis conducted by actors, taking into account regulatory and health aspects, economic and financial losses, technical and practical factors; 4) the level of cooperation within the socio-technical network. We discussed how early detection may be improved by revising the definition of abortion, extending the time frame for notification and generalising the differential diagnosis of the causes of abortion. Conclusions In contrast to quantitative approaches, qualitative studies can identify the factors (including unknown factors) influencing the decision-making process of field actors and reveal why they take those factors into consideration. Our qualitative study sheds light on the factors underlying the poor sensitivity of clinical brucellosis surveillance system for cattle in France, and suggests that early detection may be improved by considering actors’ perceptions. We believe our findings may provide further insight into ways of improving other clinical surveillance systems and thus reduce the risk of disease. PMID:24762103

Prenatal mortality is an important cause of production losses in the livestock industry. This study estimates the prevalences of abortion and stillbirth in a beef cattle system and determines the significance of some risk factors, in the tropics of Mexico. Data were obtained from a Zebu cattle herd and their crosses with Bos taurus breeds, in Yucatan, Mexico. The logit of the probability of an abortion or stillbirth was modeled using binary logistic regression. The risk factors tested were: year of abortion (or calving), season of abortion (or calving), parity number and dam breed group. The effect of twins on stillbirth was tested using Fisher exact test. Of the 4175 calvings studied 49 were abortions (1.17%). Significant factors in the logistic regression analysis for abortions were season of abortion and parity number. The risk of abortion was lower in the dry seasons compared to the rainy and windy seasons (P = 0.009). The risk of abortion was higher in second parity cows followed by the third and first parity cows, as compared to older cows (P = 0.015). Of the 4126 births, 87 were stillbirths (2.11%). Significant factors in the logistic regression analysis for stillbirth were year of calving (P = 0.0001) and parity number (P < 0.001). The risk of stillbirth in first parity cows was 2.6 times that of old cows. Of the total births, 15 were twins (0.36%) of which 7 were born dead calves. Herd owners must focus on the significant risk factors under their control to reduce the prevalence of prenatal mortality.
Algorithm for Determination of Orion Ascent Abort Mode Achievability

NASA Technical Reports Server (NTRS)

Tedesco, Mark B.

2011-01-01

For human spaceflight missions, a launch vehicle failure poses the challenge of returning the crew safely to earth through environments that are often much more stressful than the nominal mission. Manned spaceflight vehicles require continuous abort capability throughout the ascent trajectory to protect the crew in the event of a failure of the launch vehicle. To provide continuous abort coverage during the ascent trajectory, different types of Orion abort modes have been developed. If a launch vehicle failure occurs, the crew must be able to quickly and accurately determine the appropriate abort mode to execute. Early in the ascent, while the Launch Abort System (LAS) is attached, abort mode selection is trivial, and any failures will result in a LAS abort. For failures after LAS jettison, the Service Module (SM) effectors are employed to perform abort maneuvers. Several different SM abort mode options are available depending on the current vehicle location and energy state. During this region of flight the selection of the abort mode that maximizes the survivability of the crew becomes non-trivial. To provide the most accurate and timely information to the crew and the onboard abort decision logic, on-board algorithms have been developed to propagate the abort trajectories based on the current launch vehicle performance and to predict the current abort capability of the Orion vehicle. This paper will provide an overview of the algorithm architecture for determining abort achievability as well as the scalar integration scheme that makes the onboard computation possible. Extension of the algorithm to assessing abort coverage impacts from Orion design modifications and launch vehicle trajectory modifications is also presented.

Health systems could obtain substantial cost savings by providing safe abortion care rather than providing expensive treatment for complications of unsafely performed abortions. This study estimates current health system costs of treating unsafe abortion complications and compares these findings with newly-projected costs for providing safe abortion in Malawi. We conducted in-depth surveys of medications, supplies, and time spent by clinical personnel dedicated to postabortion care (PAC) for three treatment categories (simple, severe non-surgical, and severe surgical complications) and three uterine evacuation (UE) procedure types (manual vacuum aspiration (MVA), dilation and curettage (D&C) and misoprostol-alone) at 15 purposively-selected public health facilities. Per-case treatment costs were calculated and applied to national, annual PAC caseload data. The median cost per D&C case ($63) was 29% higher than MVA treatment ($49). Costs to treat severe non-surgical complications ($63) were almost five times higher than those of a simple PAC case ($13). Severe surgical complications were especially costly to treat at $128. PAC treatment in public facilities cost an estimated $314,000 annually. Transition to safe, legal abortion would yield an estimated cost reduction of 20%-30%. The method of UE and severity of complications have a large impact on overall costs. With a liberalized abortion law and implementation of induced abortion services with WHO-recommended UE methods, current PAC costs to the health system could markedly decrease.
Post abortion syndrome?

PubMed

1987-12-01

There is general agreement that uncertainty persists regarding the psychological sequelae of abortion. Inconsistencies of interpretation stem from a lack of consensus about the symptoms, severity, and duration of mental disorder. In addition, opinions differ based on individual case studies and there is no national reporting system or adequate follow up system. Frequently, reviews combine studies conducted prior to and after the 1973 Supreme Court decision, mix elective abortion with those induced for medical reasons, or fail to distinguish between abortions performed early or late in gestation. The literature reveals methodological problems, a lack of controls, and sampling inadequacies. A review of the available literature and the files of "Abortion Research Notes" suggests that women at particular risk for postabortion stress reactions are those who terminate an originally wanted pregnancy, are strongly ambivalent, come very late in their pregnancy, or lack the support of significant others.
Youth often risk unsafe abortions.

PubMed

Barnett, B

1993-10-01

The topic of this article is the use of unsafe abortion for unwanted pregnancies among adolescents. The significance of unsafe abortion is identified as a high risk of serious health problems, such as infection, hemorrhage, infertility, and mortality, and as a strain on emergency room services. The World Health Organization estimates that at least 33% of all women seeking hospital care for abortion complications are aged under 20 years. 50 million abortions are estimated to be induced annually, of which 33% are illegal and almost 50% are performed outside the health care system. Complications are identified as occurring due to the procedure itself (perforation of the uterus, cervical lacerations, or hemorrhage) and due to incomplete abortion or introduction of bacteria into the uterus. Long-term complications include an increased risk of ectopic pregnancy, chronic pelvic infection, and infertility. Mortality from unsafe abortion is estimated at 1000/100,000 procedures. Safe abortion mortality is estimated at 0.6/100,000. When infertility results, some cultures ascribe an outcast status or marriages are prevented or prostitution is assured. The risk of complications is considered higher for adolescents. Adolescents tend to delay seeking an abortion, lack knowledge on where to go for a safe procedure, and delay seeking help for complications. Peer advice may be limited or inadequate knowledge. Five studies are cited that illustrate the impact of unsafe abortion on individuals and health care systems. Abortions may be desired due to fear of parental disapproval of the pregnancy, abandonment by the father, financial and emotional responsibilities of child rearing, expulsion from school, or inability to marry if the child is out of wedlock. Medical, legal, and social barriers may prevent women and girls from obtaining safe abortion. Parental permission is sometimes a requirement for safe abortion. Fears of judgmental or callous health personnel may be barriers to seeking safe abortion. Some countries lack adequately trained medical personnel and supplies. Mortality and morbidity declines are considered possible with legalization, more trained health personnel, and family planning programs for youth and education for parents.

FASTEMP analyzes the steady state or transient temperature response of a thermal model defined in rectangular, cylindrical, conical and/or spherical coordinate system. FASTEMP provides the user with a large selection of subroutines for heat transfer calculations. The various modes of heat transfer available from these subroutines are: heat storage, conduction, radiation, heat addition or generation, convection, and fluid flow.
A Dynamic Risk Model for Evaluation of Space Shuttle Abort Scenarios

NASA Technical Reports Server (NTRS)

Henderson, Edward M.; Maggio, Gaspare; Elrada, Hassan A.; Yazdpour, Sabrina J.

2003-01-01

The Space Shuttle is an advanced manned launch system with a respectable history of service and a demonstrated level of safety. Recent studies have shown that the Space Shuttle has a relatively low probability of having a failure that is instantaneously catastrophic during nominal flight as compared with many US and international launch systems. However, since the Space Shuttle is a manned. system, a number of mission abort contingencies exist to primarily ensure the safety of the crew during off-nominal situations and to attempt to maintain the integrity of the Orbiter. As the Space Shuttle ascends to orbit it transverses various intact abort regions evaluated and planned before the flight to ensure that the Space Shuttle Orbiter, along with its crew, may be returned intact either to the original launch site, a transoceanic landing site, or returned from a substandard orbit. An intact abort may be initiated due to a number of system failures but the highest likelihood and most challenging abort scenarios are initiated by a premature shutdown of a Space Shuttle Main Engine (SSME). The potential consequences of such a shutdown vary as a function of a number of mission parameters but all of them may be related to mission time for a specific mission profile. This paper focuses on the Dynamic Abort Risk Evaluation (DARE) model process, applications, and its capability to evaluate the risk of Loss Of Vehicle (LOV) due to the complex systems interactions that occur during Space Shuttle intact abort scenarios. In addition, the paper will examine which of the Space Shuttle subsystems are critical to ensuring a successful return of the Space Shuttle Orbiter and crew from such a situation.

Emergency preparedness relies on the ability to detect patterns in rare incidents in an early stage of an outbreak in order to implement relevant actions. Early warning of an abortion storm as a result of infection with a notifiable disease, e.g. brucellosis, bovine viral diarrhea (BVD) or infectious bovine rhinotracheitis (IBR), is a significant surveillance tool. This study used data from 507 large Danish dairy herds. A modified two-stage method for detecting an unusual increase in the abortion incidence was applied to the data. An alarm was considered true if an abortion were detected in the month following the alarm month, otherwise false. The total number of abortions that could potentially be avoided if effective action were taken ranged from 769 (22.9%) to 10 (0.3%), as the number of abortions required to set the alarm increased from 1 to 6. The vast majority of abortions could, however, not be predicted, much less prevented, given this early-warning system. The false to true alarm ratio was reduced when the number of abortions that set the alarm increased. The financial scenarios evaluated demonstrated that the value of an abortion, the cost of responding to an alarm and the efficiency of the actions are important for decision making when reporting an alarm. The presented model can readily be extended to other disease problems and multiple-time periods.

Background Abortion was legalized in Nepal in 2002, following advocacy efforts highlighting high maternal mortality from unsafe abortion. We sought to assess whether legalization led to reductions in the most serious maternal health consequences of unsafe abortion. Methods We conducted retrospective medical chart review of all gynecological cases presenting at four large public referral hospitals in Nepal. For the years 2001–2010, all cases of spontaneous and induced abortion complications were identified, abstracted, and coded to classify cases of serious infection, injury, and systemic complications. We used segmented Poisson and ordinary logistic regression to test for trend and risks of serious complications for three time periods: before implementation (2001–2003), early implementation (2004–2006), and later implementation (2007–2010). Results 23,493 cases of abortion complications were identified. A significant downward trend in the proportion of serious infection, injury, and systemic complications was observed for the later implementation period, along with a decline in the risk of serious complications (OR 0.7, 95% CI 0.64, 0.85). Reductions in sepsis occurred sooner, during early implementation (OR 0.6, 95% CI 0.47, 0.75). Conclusion Over the study period, health care use and the population of reproductive aged women increased. Total fertility also declined by nearly half, despite relatively low contraceptive prevalence. Greater numbers of women likely obtained abortions and sought hospital care for complications following legalization, yet we observed a significant decline in the rate of serious abortion morbidity. The liberalization of abortion policy in Nepal has benefited women’s health, and likely contributes to falling maternal mortality in the country. The steepest decline was observed after expansion of the safe abortion program to include midlevel providers, second trimester training, and medication abortion, highlighting the importance of concerted efforts to improve access. Other countries contemplating changes to abortion policy can draw on the evidence and implementation strategies observed in Nepal. PMID:23741391

Reverse Launch Abort System Parachute Architecture Trade Study

Litton, Daniel K.; O'Keefe, Stephen A.; Winski, Richard G.

2011-01-01

This study investigated a potential Launch Abort System (LAS) Concept of Operations and abort parachute architecture. The purpose of the study was to look at the concept of jettisoning the LAS tower forward (Reverse LAS or RLAS) into the free-stream flow rather than after reorienting to a heatshield forward orientation. A hypothesized benefit was that due to the compressed timeline the dynamic pressure at main line stretch would be substantially less. This would enable the entry parachutes to be designed and sized based on entry loading conditions rather than the current stressing case of a Pad Abort. Ultimately, concerns about the highly dynamic reorientation of the CM via parachutes, and the additional requirement of a triple bridle attachment for the RLAS parachute system, overshadowed the potential benefits and ended this effort.
Moving from legality to reality: how medical abortion methods were introduced with implementation science in Zambia.

Although abortion is technically legal in Zambia, the reality is far more complicated. This study describes the process and results of galvanizing access to medical abortion where abortion has been legal for many years, but provision severely limited. It highlights the challenges and successes of scaling up abortion care using implementation science to document 2 years of implementation. An intervention between the Ministry of Health, University Teaching Hospital and the international organization Ipas, was established to introduce medical abortion and to address the lack of understanding and implementation of the country's abortion law. An implementation science model was used to evaluate effectiveness and glean lessons for other countries about bringing safe and legal abortion services to scale. The intervention involved the provision of Comprehensive Abortion Care services in 28 public health facilities in Zambia for a 2 year period, August 2009 to September 2011. The study focused on three main areas: building health worker capacity in public facilities and introducing medical abortion, working with pharmacists to provide improved information on medical abortion, and community engagement and mobilization to increase knowledge of abortion services and rights through stronger health system and community partnerships. After 2 years, 25 of 28 sites provided abortion services, caring for more than 13,000 women during the intervention. For the first time, abortion was decentralized, 19% of all abortion care was performed in health centers. At the end of the intervention, all providing facilities had managers supportive of continuing legal abortion services. When asked about the impact of medical abortion provision, a number of providers reported that medical abortion improved their ability to provide affordable safe abortion. In neighboring pharmacies only 19% of mystery clients visiting them were offered misoprostol for purchase at baseline, this increased to 47% after the intervention. Despite progress in attitudes towards abortion clients, such as empathy, and improved community engagement, the evaluation revealed continuing stigma on both provider and client sides. These findings provide a case study of the medical abortion introduction in Zambia and offer important lessons for expanding safe and legal abortion access in similar settings across Africa.

CAPE CANAVERAL, Fla. - The second set of two Ogive panels for the Orion Launch Abort System have arrived at the Launch Abort System Facility, or LASF, at NASA’s Kennedy Space Center in Florida. One of the Ogive panels has been uncrated and is being lifted by crane for placement on a work stand. During processing, the panels will be secured around the Orion crew module and attached to the Launch Abort System. Orion is the exploration spacecraft designed to carry astronauts to destinations not yet explored by humans, including an asteroid and Mars. It will have emergency abort capability, sustain the crew during space travel and provide safe re-entry from deep space return velocities. The first unpiloted test flight of Orion is scheduled to launch in 2014 atop a Delta IV rocket and in 2017 on NASA’s Space Launch System rocket. For more information, visit www.nasa.gov/orion.

Two tests supporting development of the launch abort system for the Orion MultiPurpose Crew Vehicle were run in the NASA Ames Unitary Plan wind tunnel last year. The first test used a fully metric model to examine the stability and controllability of the Launch Abort Vehicle during potential abort scenarios for Mach numbers ranging from 0.3 to 2.5. The aerodynamic effects of the Abort Motor and Attitude Control Motor plumes were simulated using high-pressure air flowing through independent paths. The aerodynamic effects of the proximity to the launch vehicle during the early moments of an abort were simulated with a remotely actuated Service Module that allowed the position relative to the Crew Module to be varied appropriately. The second test simulated the acoustic environment around the Launch Abort Vehicle caused by the plumes from the 400,000-pound thrust, solid-fueled Abort Motor. To obtain the proper acoustic characteristics of the hot rocket plumes for the flight vehicle, heated Helium was used. A custom Helium supply system was developed for the test consisting of 2 jumbo high-pressure Helium trailers, a twelve-tube accumulator, and a 13MW gas-fired heater borrowed from the Propulsion Simulation Laboratory at NASA Glenn Research Center. The test provided fluctuating surface pressure measurements at over 200 points on the vehicle surface that have now been used to define the ground-testing requirements for the Orion Launch Abort Vehicle.

Through more than a decade of operation, we have noticed the phenomena of beam loss induced kicker instability in the RHIC beam abort systems. In this study, we analyze the short term beam loss before abort kicker pre-fire events and operation conditions before capacitor failures. Beam loss has caused capacitor failures and elevated radiation level concentrated at failed end of capacitor has been observed. We are interested in beam loss induced radiation and heat dissipation in large oil filled capacitors and beam triggered thyratron conduction. We hope the analysis result would lead to better protection of the abort systems andmore » improved stability of the RHIC operation.« less
Pitch Guidance Optimization for the Orion Abort Flight Tests

NASA Technical Reports Server (NTRS)

Stillwater, Ryan Allanque

2010-01-01

The National Aeronautics and Space Administration created the Constellation program to develop the next generation of manned space vehicles and launch vehicles. The Orion abort system is initiated in the event of an unsafe condition during launch. The system has a controller gains schedule that can be tuned to reduce the attitude errors between the simulated Orion abort trajectories and the guidance trajectory. A program was created that uses the method of steepest descent to tune the pitch gains schedule by an automated procedure. The gains schedule optimization was applied to three potential abort scenarios; each scenario tested using the optimized gains schedule resulted in reduced attitude errors when compared to the Orion production gains schedule.

Turkey has maintained liberal contraception and abortion policies since the 1980s. In 2012, the government proposed to restrict abortion; a bill limiting abortion was later drafted but never passed into law. Since the proposed restriction, women have reported difficulty accessing abortion services across Turkey. We aimed to better understand the current availability of abortion and reproductive health services in Istanbul and explore whether access to services has changed since 2012. In 2015, we completed 14 in-depth interviews with women and 11 semi-structured interviews with key informants. We transcribed all interviews and completed content and thematic analyses of the data. Key informants had good knowledge about the political discourse and the current abortion law. In contrast, women were familiar with the political discourse but had mixed information about the current status of abortion and were unsure about the legality of their own abortions. There was consensus that access to services has become more limited in the last five years due to the political climate, thus advocacy to prioritize reproductive health services, and abortion care in particular, in the public health system are needed.

Integrated Flight Performance Analysis of a Launch Abort System Concept

NASA Technical Reports Server (NTRS)

Tartabini, Paul V.

2007-01-01

This paper describes initial flight performance analyses conducted early in the Orion Project to support concept feasibility studies for the Crew Exploration Vehicle s Launch Abort System (LAS). Key performance requirements that significantly affect abort capability are presented. These requirements have implications on sizing the Abort Motor, tailoring its thrust profile to meet escape requirements for both launch pad and high drag/high dynamic pressure ascent aborts. Additional performance considerations are provided for the Attitude Control Motor, a key element of the Orion LAS design that eliminates the need for ballast and provides performance robustness over a passive control approach. Finally, performance of the LAS jettison function is discussed, along with implications on Jettison Motor sizing and the timing of the jettison event during a nominal mission. These studies provide an initial understanding of LAS performance that will continue to evolve as the Orion design is matured.
Pregnancy and the 40-Year Prison Sentence

Abstract Using the case of El Salvador, this article demonstrates how the anti-abortion catchphrase “abortion is murder” can become embedded in the legal practice of state judicial systems. In the 1990s, a powerful anti-abortion movement in El Salvador resulted in a new legal context that outlawed abortion in all circumstances, discouraged mobilization for abortion rights, and encouraged the prosecution of reproduction-related “crimes.” Within this context, Salvadoran women initially charged with the crime of abortion were convicted of “aggravated homicide” and sentenced to up to 40 years in prison. Court documents suggest that many of these women had not undergone abortions, but had suffered naturally occurring stillbirths late in their pregnancies. Through analysis of newspaper articles and court cases, this article documents how El Salvador came to prosecute obstetrical emergencies as “murder,” and concludes that activism on behalf of abortion rights is central to protecting poor pregnant women from prosecution for reproduction-related “crimes.” PMID:28630543
Dynamic Modeling of Ascent Abort Scenarios for Crewed Launches

For the last 30 years, the United States' human space program has been focused on low Earth orbit exploration and operations with the Space Shuttle and International Space Station programs. After over 40 years, the U.S. is again working to return humans beyond Earth orbit. To do so, NASA is developing a new launch vehicle and spacecraft to provide this capability. The launch vehicle is referred to as the Space Launch System (SLS) and the spacecraft is called Orion. The new launch system is being developed with an abort system that will enable the crew to escape launch failures that would otherwise be catastrophic as well as probabilistic design requirements set for probability of loss of crew (LOC) and loss of mission (LOM). In order to optimize the risk associated with designing this new launch system, as well as verifying the associated requirements, NASA has developed a comprehensive Probabilistic Risk Assessment (PRA) of the integrated ascent phase of the mission that includes the launch vehicle, spacecraft and ground launch facilities. Given the dynamic nature of rocket launches and the potential for things to go wrong, developing a PRA to assess the risk can be a very challenging effort. Prior to launch and after the crew has boarded the spacecraft, the risk exposure time can be on the order of three hours. During this time, events may initiate from either the spacecraft, the launch vehicle, or the ground systems, thus requiring an emergency egress from the spacecraft to a safe ground location or a pad abort via the spacecraft's launch abort system. Following launch, again either the spacecraft or the launch vehicle can initiate the need for the crew to abort the mission and return home. Obviously, there are thousands of scenarios whose outcome depends on when the abort is initiated during ascent and how the abort is performed. This includes modeling the risk associated with explosions and benign system failures that require aborting a spacecraft under very dynamic conditions, particularly in the lower atmosphere, and returning the crew home safely. This paper will provide an overview of the PRA model that has been developed of this new launch system, including some of the challenges that are associated with this effort.
Why don't humanitarian organizations provide safe abortion services?

PubMed

McGinn, Therese; Casey, Sara E

2016-01-01

Although sexual and reproductive health services have become more available in humanitarian settings over the last decade, safe abortion services are still rarely provided. The authors' observations suggest that four reasons are typically given for this gap: 'There's no need'; 'Abortion is too complicated to provide in crises'; 'Donors don't fund abortion services'; and 'Abortion is illegal'. However, each of these reasons is based on false premises. Unsafe abortion is a major cause of maternal mortality globally, and the collapse of health systems in crises suggests it likely increases in humanitarian settings. Abortion procedures can be safely performed in health centers by mid-level providers without sophisticated equipment or supplies. Although US government aid does not fund abortion-related activities, other donors, including many European governments, do fund abortion services. In most countries, covering 99 % of the world's population, abortion is permitted under some circumstances; it is illegal without exception in only six countries. International law supports improved access to safe abortion. As none of the reasons often cited for not providing these services is valid, it is the responsibility of humanitarian NGOs to decide where they stand regarding their commitment to humanitarian standards and women's right to high quality and non-discriminatory health services. Providing safe abortion to women who become pregnant as a result of rape in war may be a more comfortable place for organizations to begin the discussion. Making safe abortion available will improve women's health and human rights and save lives.

This paper discusses the implementation of abort gap beam intensity monitoring at the Tevatron collider at Fermilab. There are two somewhat independent monitors which measure the intensity of the synchrotron light emitted by particles in the abort gaps. One system uses a gated Photomultiplier Tube (PMT) to measure the light intensity, and the other system uses a single lens telescope, gated image intensifier, and Charge Injection Device (CID) camera to image the beam.

Introduction Unsafe and illegal abortions are the third leading cause of maternal death. It affects physical, emotional and social health of women and their families. Abortion is a multi-dimensional phenomenon with several social, legal, and religious implications. The views of policy-makers affect the approach to abortion in every society. Understanding the attitudes and knowledge of high-ranking decision makers towards abortion was the purpose of this study. Materials and Methods A qualitative research was implemented by carrying out individual interviews with 29 out of a selection of 80 presidents of medical sciences universities, senior executive managers in the legal system, forensic medicine and decision-makers in the health system and a number of top Muslim clerics, using a semi-structured questionnaire for data gathering. Content analysis revealed the results. Results There were considerable unwillingness and reluctance among the interviewees to participate in the study. The majority of participants fairly knew about the prevalence of illegal abortions and their complications. There was strong agreement on abortion when health of the mother or the fetus was at risk. Abortion for reproductive health reasons was supported by a minority of the respondents. The majority of them disagreed with abortion when pregnancy was the result of a rape, temporary marriage or out of wedlock affairs. Making decision for abortion by the pregnant mother, as a matter of her right, did not gain too much approval. Conclusion It seemed that physical health of the mother or the fetus was of more importance to the respondents than their mental or social health. The mother's hardship was not any indication for induced abortion in the viewpoints of the interviewed policy-makers. Strengthening family planning programs, making appropriate laws in lines with religious orders and advocacy programs targeting decision makers are determined as strategies for improving women's health rights.

Spontaneous abortion in early pregnancy due to unknown reasons is a common problem. The excess complement activation and consequent placental inflammation and anti-angiogenic milieu is emerging as an important associated factor in many pregnancy-related complications. In the present study we sought to examine the expression of complement inhibitory proteins at the feto-maternal interface and levels of complement split products in the circulation to understand their role in spontaneous abortion. Consenting pregnant women who either underwent elective abortion due to non-clinical reasons (n = 13) or suffered miscarriage (n = 14) were recruited for the study. Systemic levels of complement factors C3a and C5a were measured by enzyme-linked immunosorbent assay (ELISA). Plasma C5 and C3 protein levels were examined by Western blot. Expressions of complement regulatory proteins such as CD46 and CD55 in the decidua were investigated by quantitative polymerase chain reaction (PCR) and Western blot. The median of plasma C3a level was 82·83 ng/ml and 66·17 ng/ml in elective and spontaneous abortion patients, respectively. Medians of plasma C5a levels in elective and spontaneous abortion patients were 0·96 ng/ml and 1·14 ng/ml, respectively. Only plasma C5a levels but not C3a levels showed significant elevation in spontaneous abortion patients compared to elective abortion patients. Further, there was a threefold decrease in the mRNA expressions of complement inhibitory proteins CD46 and CD55 in the decidua obtained from spontaneous abortion patients compared to that of elective abortion patients. These data suggested that dysregulated complement cascade may be associated with spontaneous abortion. © 2014 British Society for Immunology.
Study of fail-safe abort system for an actively cooled hypersonic aircraft, volume 2

Peeples, M. E.; Herring, R. L.

1976-01-01

Conceptual designs of a fail-safe abort system for hydrogen fueled actively cooled high speed aircraft are examined. The fail-safe concept depends on basically three factors: (1) a reliable method of detecting a failure or malfunction in the active cooling system, (2) the optimization of abort trajectories which minimize the descent heat load to the aircraft, and (3) fail-safe thermostructural concepts to minimize both the weight and the maximum temperature the structure will reach during descent. These factors are examined and promising approaches are evaluated based on weight, reliability, ease of manufacture and cost.
Key Role of Capsular Polysaccharide in the Induction of Systemic Infection and Abortion by Hypervirulent Campylobacter jejuni

ABSTRACT Campylobacter jejuni is a zoonotic pathogen, and a hypervirulent clone, named clone SA, has recently emerged as the predominant cause of ovine abortion in the United States. To induce abortion, orally ingested Campylobacter must translocate across the intestinal epithelium, spread systemically in the circulation, and reach the fetoplacental tissue. Bacterial factors involved in these steps are not well understood. C. jejuni is known to produce capsular polysaccharide (CPS), but the specific role that CPS plays in systemic infection and particularly abortion in animals remains to be determined. In this study, we evaluated the role of CPS in bacteremia using a mouse model and in abortion using a pregnant guinea pig model following oral challenge. Compared with C. jejuni NCTC 11168 and 81-176, a clone SA isolate (IA3902) resulted in significantly higher bacterial counts and a significantly longer duration of bacteremia in mice. The loss of capsule production via gene-specific mutagenesis in IA3902 led to the complete abolishment of bacteremia in mice and abortion in pregnant guinea pigs, while complementation of capsule expression almost fully restored these phenotypes. The capsule mutant strain was also impaired for survival in guinea pig sera and sheep blood. Sequence-based analyses revealed that clone SA possesses a unique CPS locus with a mosaic structure, which has been stably maintained in all clone SA isolates derived from various hosts and times. These findings establish CPS as a key virulence factor for the induction of systemic infection and abortion in pregnant animals and provide a viable candidate for the development of vaccines against hypervirulent C. jejuni.

OBJECTIVE To analyze temporal trends and distribution patterns of unsafe abortion in Brazil. METHODS Ecological study based on records of hospital admissions of women due to abortion in Brazil between 1996 and 2012, obtained from the Hospital Information System of the Ministry of Health. We estimated the number of unsafe abortions stratified by place of residence, using indirect estimate techniques. The following indicators were calculated: ratio of unsafe abortions/100 live births and rate of unsafe abortion/1,000 women of childbearing age. We analyzed temporal trends through polynomial regression and spatial distribution using municipalities as the unit of analysis. RESULTS In the study period, a total of 4,007,327 hospital admissions due to abortions were recorded in Brazil. We estimated a total of 16,905,911 unsafe abortions in the country, with an annual mean of 994,465 abortions (mean unsafe abortion rate: 17.0 abortions/1,000 women of childbearing age; ratio of unsafe abortions: 33.2/100 live births). Unsafe abortion presented a declining trend at national level (R2: 94.0%, p < 0.001), with unequal patterns between regions. There was a significant reduction of unsafe abortion in the Northeast (R2: 93.0%, p < 0.001), Southeast (R2: 92.0%, p < 0.001) and Central-West regions (R2: 64.0%, p < 0.001), whereas the North (R2: 39.0%, p = 0.030) presented an increase, and the South (R2: 22.0%, p = 0.340) remained stable. Spatial analysis identified the presence of clusters of municipalities with high values for unsafe abortion, located mainly in states of the North, Northeast and Southeast Regions. CONCLUSIONS Unsafe abortion remains a public health problem in Brazil, with marked regional differences, mainly concentrated in the socioeconomically disadvantaged regions of the country. Qualification of attention to women’s health, especially to reproductive aspects and attention to pre- and post-abortion processes, are necessary and urgent strategies to be implemented in the country.

Bovine abortion surveillance is essential for human and animal health because it plays an important role in the early warning of several diseases. Due to the limited sensitivity of traditional surveillance systems, there is a growing interest for the development of syndromic surveillance. Our objective was to assess whether, routinely collected, artificial insemination (AI) data could be used, as part of a syndromic surveillance system, to devise an indicator of mid-term abortions in dairy cattle herds in France. A mid-term abortion incidence rate (MAIR) was computed as the ratio of the number of mid-term abortions to the number of female-weeks at risk. A mid-term abortion was defined as a return-to-service (i.e., a new AI) taking place 90 to 180 days after the previous AI. Weekly variations in the MAIR in heifers and parous cows were modeled with a time-dependent Poisson model at the département level (French administrative division) during the period of 2004 to 2010. The usefulness of monitoring this indicator to detect a disease-related increase in mid-term abortions was evaluated using data from the 2007-2008 episode of bluetongue serotype 8 (BT8) in France. An increase in the MAIR was identified in heifers and parous cows in 47% (n = 24) and 71% (n = 39) of the departements. On average, the weekly MAIR among heifers increased by 3.8% (min-max: 0.02-57.9%) when the mean number of BT8 cases that occurred in the previous 8 to 13 weeks increased by one. The weekly MAIR among parous cows increased by 1.4% (0.01-8.5%) when the mean number of BT8 cases occurring in the previous 6 to 12 weeks increased by one. These results underline the potential of the MAIR to identify an increase in mid-term abortions and suggest that it is a good candidate for the implementation of a syndromic surveillance system for bovine abortions.

[Comparison between lymphocytic infiltration in early spontaneous abortions and in elective abortions with signs of disruption at the chorio-decidual interface].

PubMed

Caliendo, L

2007-12-01

The aim of the study was to compare lymphocytic infiltrations in early spontaneous abortions with those with signs of disruption at the chorio-decidual interface in elective abortions. Determinations were performed on preparations received at the Anatomy-Pathology Services of Ospedale San Paolo, Savona (Italy) in 2005. Immunohistochemistry studies were performed using antisera CD3, CD4 and CD14 with a DAB detection kit on a Ventana BenchMark automated slide staining system. The material was grouped into three classes: early spontaneous abortions (class 1); elective abortions with signs of disruption at the chorio-decidual interface (class 2); elective abortions without such signs (class 3). Preparations from classes 1 and 2 shared a similar picture of lymphocytic activation and the presence of macrophagic elements. The test results demonstrated that the proportion of the T cell population increased with the rise in CD8+ lymphocytes in both class 1 and class 2 preparations. The results indicate that T-cell-mediated immune activation may the cause or one of the causes of spontaneous abortion and that the effects of disruption at the chorio-decidual interface observed in elective abortion provide a clue to initial signs of loss of pregnancy. From the discovery of a population without evident signs of active abortion (elective abortion with a disturbed chorio-decidual interface) but with evidence of initial lymphocytic activation compared with that devoid of such signs (elective abortion) one can conjecture that lymphocytic activation is a major factor in the process leading to early spontaneous abortion.

Allowing a broader range of trained health workers to deliver services can be an important way of improving access to safe abortion care. However, the expansion of health worker roles may be challenging to implement. This study aimed to explore factors influencing the implementation of role expansion strategies for non-physician providers to include the delivery of abortion care. We conducted a multi-country case study synthesis in Bangladesh, Ethiopia, Nepal, South Africa and Uruguay, where the roles of non-physician providers have been formally expanded to include the provision of abortion care. We searched for documentation from each country related to non-physician providers, abortion care services and role expansion through general internet searches, Google Scholar and PubMed, and gathered feedback from 12 key informants. We carried out a thematic analysis of the data, drawing on categories from the SURE Framework of factors affecting the implementation of policy options. Several factors appeared to affect the successful implementation of including non-physician providers to provide abortion care services. These included health workers' knowledge about abortion legislation and services; and health workers' willingness to provide abortion care. Health workers' willingness appeared to be influenced by their personal views about abortion, the method of abortion and stage of pregnancy and their perceptions of their professional roles. While managers' and co-workers' attitudes towards the use of non-physician providers varied, the synthesis suggests that female clients focused less on the type of health worker and more on factors such as trust, privacy, cost, and closeness to home. Health systems factors also played a role, including workloads and incentives, training, supervision and support, supplies, referral systems, and monitoring and evaluation. Strategies used, with varying success, to address some of these issues in the study countries included values clarification workshops, health worker rotation, access to emotional support for health workers, the incorporation of abortion care services into pre-service curricula, and in-service training strategies. To increase the likelihood of success for role expansion strategies in the area of safe abortion, programme planners must consider how to ensure motivation, support and reasonable working conditions for affected health workers.

Despite recent studies showing evidence that the organisation of the French health care system raises some problems concerning access to abortion, far little is known on the reality of access conditions and the views of women on the difficulties they experience when they attend an abortion clinic. In this article, we discuss the complementarity of materials from two surveys one qualitative, the other quantitative in the study of patterns of care for an abortion. The qualitative survey included 51 women who reported a history of induced abortion, selected from a qualitative study on unintended pregnancy in France. The quantitative survey included 480 women, who had an abortion in the past 10 years. These women were selected from a representative sample of 2863 women aged 18 to 44, who participated in a study on contraception and abortion. The variety of patterns of care for an abortion, the rareness of dysfunctions in the health care system and the importance of the first professional women contacted, demonstrated in the qualitative survey, were confirmed in the quantitative survey. The quantitative survey enabled quantifying the distribution of the different patterns of care. It also permitted to identify factors associated with the choice of first professional contacted and with the type of subsequent patterns of care. The qualitative survey permitted to explore these patterns of care and to highlight the interaction between the women's request and the representation of the legitimacy of their request. Difficulties of access seemed to be linked to the lack of support women experienced in the process of finding an abortion clinic. Results suggest that general practitioners are less well informed of the procedures required for an abortion than other professionals. However, the qualitative survey also shows that problems of access cannot be reduced to the lack of information of professionals, as their practice was also linked to their own representation of abortion, and their perception of the legitimacy of the women's request. Our results underline the need for the definition of a clear health policy that should include two priorities: the improvement of the visibility of health care supply for an abortion and the promotion of information delivered to health care professionals.

Unsafe abortion: a cruel way of birth control.

Unsafe abortion refers to a procedure for terminating an unintended pregnancy performed either by persons lacking the necessary skills or in an environment that does not conform to minimal medical standards, or both. The objectives of the study are to assess the factors attributing to practice of unsafe abortion and to suggest feasible and cost-effective measures to counter the same. An extensive search of all materials related to the topic was made using library sources including Pubmed, Medline and World Health Organization. Keywords used in the search include unsafe abortion and unintended pregnancy. Multiple socio-demographic determinants and barriers such as illiterate women, poor socio-economic status, poor awareness about abortion services, associated stigma, and untrained health professionals have been identified resulting in restricted utilization/access of women to safe abortion services. Consequences of unsafe abortion have been alarming, seriously questioning the quality of health care delivery system. Concerted and dedicated efforts of government in collaboration with the private sector, community members and non-governmental organizations are needed to ensure that women have a better access to contraceptives, abortion services, and post-abortion care that are safe, affordable, and free from stigma.
Psychosocial aspects of abortion

PubMed Central

Illsley, Raymond; Hall, Marion H.

The literature on psychosocial aspects of abortion is confusing. Individual publications must be interpreted in the context of cultural, religious, and legal constraints obtaining in a particular society at a given time, with due attention to the status and availability of alternatives to abortion that might be chosen by a woman with an “unwanted” pregnancy. A review of the literature shows that, where careful pre- and post-abortion assessments are made, the evidence is that psychological benefit commonly results, and serious adverse emotional sequelae are rare. The outcome of refused abortion seems less satisfactory, with regrets and distress frequently occurring. Research on the administration of abortion services suggests that counselling is often of value, that distress is frequently caused by delays in deciding upon and in carrying out abortions, and by unsympathetic attitudes of service providers. The phenomenon of repeated abortion seeking should be seen in the context of the availability and cost of contraception and sterilization. The place of sterilization with abortion requires careful study. A recommendation is made for observational descriptive research on populations of women with potentially unwanted pregnancies in different cultures, with comparisons of management systems and an evaluation of their impact on service users.

Crew Exploration Vehicle Launch Abort Controller Performance Analysis

NASA Technical Reports Server (NTRS)

Sparks, Dean W., Jr.; Raney, David L.

2007-01-01

This paper covers the simulation and evaluation of a controller design for the Crew Module (CM) Launch Abort System (LAS), to measure its ability to meet the abort performance requirements. The controller used in this study is a hybrid design, including features developed by the Government and the Contractor. Testing is done using two separate 6-degree-of-freedom (DOF) computer simulation implementations of the LAS/CM throughout the ascent trajectory: 1) executing a series of abort simulations along a nominal trajectory for the nominal LAS/CM system; and 2) using a series of Monte Carlo runs with perturbed initial flight conditions and perturbed system parameters. The performance of the controller is evaluated against a set of criteria, which is based upon the current functional requirements of the LAS. Preliminary analysis indicates that the performance of the present controller meets (with the exception of a few cases) the evaluation criteria mentioned above.
"These things are dangerous": Understanding induced abortion trajectories in urban Zambia.

PubMed

Coast, Ernestina; Murray, Susan F

2016-03-01

Unsafe abortion is a significant but preventable cause of global maternal mortality and morbidity. Zambia has among the most liberal abortion laws in sub-Saharan Africa, however this alone does not guarantee access to safe abortion, and 30% of maternal mortality is attributable to unsafe procedures. Too little is known about the pathways women take to reach abortion services in such resource-poor settings, or what informs care-seeking behaviours, barriers and delays. In-depth qualitative interviews were conducted in 2013 with 112 women who accessed abortion-related care in a Lusaka tertiary government hospital at some point in their pathway. The sample included women seeking safe abortion and also those receiving hospital care following unsafe abortion. We identified a typology of three care-seeking trajectories that ended in the use of hospital services: clinical abortion induced in hospital; clinical abortion initiated elsewhere, with post-abortion care in hospital; and non-clinical abortion initiated elsewhere, with post-abortion care in hospital. Framework analyses of 70 transcripts showed that trajectories to a termination of an unwanted pregnancy can be complex and iterative. Individuals may navigate private and public formal healthcare systems and consult unqualified providers, often trying multiple strategies. We found four major influences on which trajectory a woman followed, as well as the complexity and timing of her trajectory: i) the advice of trusted others ii) perceptions of risk iii) delays in care-seeking and receipt of services and iv) economic cost. Even though abortion is legal in Zambia, girls and women still take significant risks to terminate unwanted pregnancies. Levels of awareness about the legality of abortion and its provision remain low even in urban Zambia, especially among adolescents. Unofficial payments required by some providers can be a major barrier to safe care. Timely access to safe abortion services depends on chance rather than informed exercise of entitlement.

Abortion in a Progressive Legal Environment: The Need for Vigilance in Protecting and Promoting Access to Safe Abortion Services in South Africa

The importance of South Africa as a model for reproductive self-determination in Africa cannot be underestimated. Abortion has been legal since 1996, and the country has some of the most developed government systems for the provision of abortion care on the continent. Yet in the same way opponents of abortion in the United States have whittled away at access with increased bureaucracy, South Africa faces similar assaults that leave women without safe care and threaten to turn back achievements made during the past 16 years. I explore the history of the law, subsequent legal challenges, and new threats to women’s access to abortion services, including service delivery issues that may influence the future of public health in the country.

The Orion Pad Abort 1 (PA-1) Flight Test: A Propulsion Success

NASA Technical Reports Server (NTRS)

Jones, Daniel S.

2015-01-01

This poster provides a concise overview of the highly successful Orion Pad Abort 1 (PA-1) flight test, and the three rocket motors that contributed to this success. The primary purpose of the Orion PA-1 flight was to help certify the Orion Launch Abort System (LAS), which can be utilized in the unlikely event of an emergency on the launchpad or during mission vehicle ascent. The PA-1 test was the first fully integrated flight test of the Orion LAS, one of the primary systems within the Orion Multi-Purpose Crew Vehicle (MPCV). The Orion MPCV is part of the architecture within the Space Launch System (SLS), which is being designed to transport astronauts beyond low-Earth orbit for future exploration missions. Had the Orion PA-1 flight abort occurred during launch preparations for a real human spaceflight mission, the PA-1 LAS would have saved the lives of the crew. The PA-1 flight test was largely successful due to the three solid rocket motors of the LAS: the Attitude Control Motor (ACM); the Jettison Motor (JM); and the Abort Motor (AM). All three rocket motors successfully performed their required functions during the Orion PA-1 flight test, flown on May 6, 2010 at the White Sands Missile Range in New Mexico, culminating in a successful demonstration of an abort capability from the launchpad.
Medical opinion on abortion in Jamaica: a national Delphi survey of physician, nurses, and midwives.

A national sample of 120 Jamaican physicians, public health nurses, and licensed midwives participated in a two-stage Delphi survey to identify medical opinion on proposed liberlization of Jamaica's abortion law, and to predict the likely impact of such legislative action on existing health and family planning services. More than 80 percent of the respondents favored legalization of abortion, and most supported changes in the health service delivery system to accommodate the expected demand. They believed that clandestine abortion, involving pharmacists and physicians, is already widely practiced.

Since 1969, CDC has conducted abortion surveillance to document the number and characteristics of women obtaining legal induced abortions in the United States. 2006. Each year, CDC requests abortion data from the central health agencies of 52 reporting areas (the 50 states, New York City, and the District of Columbia); these data are provided to CDC voluntarily. In 2006, data were received from 49 reporting areas. For the purpose of trend analysis, data were evaluated from the 46 areas that reported data every year during 1996-2006. For 2006, a total of 846,181 abortions were reported to CDC. Among the 46 areas that provided data consistently during 1996-2006, a total of 835,134 abortions (98.7% of the total) were reported; the abortion rate was 16.1 abortions per 1,000 women aged 15-44 years, and the abortion ratio was 236 abortions per 1,000 live births. During the previous decade (1997-2006), reported abortion numbers, rates, and ratios decreased 5.7%, 8.8%, and 14.8%, respectively; most of these declines occurred before 2001. During the previous year (2005-2006), the total number of abortions increased 3.1%, and the abortion rate increased 3.2%; the abortion ratio was stable. In 2006, as during the previous decade (1997-2006), women aged 20-29 years accounted for the majority (56.8%) of abortions and had the highest abortion rates (29.9 abortions per 1,000 women aged 20-24 years and 22.2 abortions per 1,000 women aged 25-29 years); by contrast, abortion ratios were highest at the extremes of reproductive age. Adolescents aged 15-19 years accounted for 16.5% of all abortions in 2006 and had an abortion rate of 14.8 abortions per 1,000 adolescents aged 15-19 years; women aged >or=35 years accounted for a smaller percentage (12.1%) of abortions and had lower abortion rates (7.8 abortions per 1,000 women aged 35-39 years and 2.6 abortions per 1,000 women aged >or=40 years). During 1997-2006, the percentage of abortions and the abortion rate increased among women aged >or=35 years but declined among adolescents aged or=21 weeks' gestation (1.3%).

Pirello, C. J.; Herring, R. L.

1976-01-01

Conceptual designs of a fail-safe abort system for hydrogen fueled actively cooled high speed aircraft are examined. The fail-safe concept depends on basically three factors: (1) a reliable method of detecting a failure or malfunction in the active cooling system, (2) the optimization of abort trajectories which minimize the descent heat load to the aircraft, and (3) fail-safe thermostructural concepts to minimize both the weight and the maximum temperature the structure will reach during descent. These factors are examined and promising approaches are evaluated based on weight, reliability, ease of manufacture and cost.

The aim of the study was to investigate the experiences linked to the post-abortion syndrome in mothers who have had a voluntary abortion. A phenomenological qualitative approach to collect the experiences of mothers who had voluntarily interrupted their pregnancy was used. The research technique was the semistructured interviews with women who had contacted different association's help of the Murcia region for support after experiencing symptoms consistent with post-abortion syndrome. The testimonies show feminist or utilitarian arguments to justify the decision to abort, they talk about a system, to some extent, mercantilist that has no real intention of giving real life choices. Experience shows that far from lived as an act of female freedom is experienced traumatically, developed symptoms following the sense of loss. In this context, the resource spiritual becomes the best tool to expiate guilt. The experience of abortion does not improve the lives of women; far from it is a trauma that can be avoided with proper advice to avoid the tragedy of abortion.

Even given the liberal abortion law in Ghana, abortion complications are a large contributor to maternal morbidity and mortality. This study sought to understand why young women seeking an abortion in a legally enabling environment chose to do this outside the formal healthcare system. Women being treated for complications arising from a self-induced abortion as well as for elective abortions at three hospitals in Ghana were interviewed. Community-based focus groups were held with women as well as men, separately. Interviews and focus group discussions were conducted until saturation was reached. A total of 18 women seeking care for complications from a self-induced abortion and 11 seeking care for an elective abortion interviewed. The women ranged in age from 13 to 35 years. There were eight focus groups; two with men and six with women. The reasons women self-induce are: (1) abortion is illegal; (2) attitudes of the healthcare workers; (3) keeping the pregnancy a secret; and (4) social network influence. The meta-theme of normalisation of self-inducing' an abortion was identified. When women are faced with an unplanned and unwanted pregnancy, they consult individuals in their social network whom they know have dealt with a similar situation. Misoprostol is widely available in Ghanaian cities and is successful at inducing an abortion for many women. In this way, self-inducing abortions using medication procured from pharmacists and chemical sellers has become normalised for women in Kumasi, Ghana. © Faculty of Sexual and Reproductive Healthcare of the Royal College of Obstetricians and Gynaecologists (unless otherwise stated in the text of the article) 2017.

In Papua New Guinea abortion is restricted under the Criminal Code Act. While safe abortions should available in certain situations, frequently they are not available to the majority of women. Sepsis from unsafe abortion is a leading cause of maternal mortality. Our findings form part of a wider, mixed methods study designed to identify complications requiring hospital treatment for post abortion care and to explore the circumstances surrounding unsafe abortion. Through a six month prospective study we identified all women presenting to the Eastern Highlands Provincial Hospital following spontaneous and induced abortions. We undertook semi-structured interviews with women and reviewed individual case notes, extracting demographic and clinical information. Case notes were reviewed for 56% (67/119) of women presenting for post abortion care. At least 24% (28/119) of these admissions were due to induced abortion. Women presenting following induced abortions were significantly more likely to be younger, single, in education at the time of the abortion and report that the baby was unplanned and unwanted, compared to those reporting spontaneous abortion. Obtained illegally, misoprostol was the method most frequently used to end the pregnancy. Physical and mechanical means and traditional herbs were also widely reported. In a country with a low contraceptive prevalence rate and high unmet need for family planning, all reproductive age women need access to contraceptive information and services to avoid, postpone or space pregnancies. In the absence of this, women are resorting to unsafe means to end an unwanted pregnancy, putting their lives at risk and putting an increased strain on an already struggling health system. Women in this setting need access to safe, effective means of abortion.

Women in this setting need access to safe, effective means of abortion. PMID:25329982

To determine the opinions and current practice of obstetricians and gynaecologists and trainees in the specialty with regard to induced abortion. A voluntary, anonymous survey of Australian Fellows and specialist trainees of the Royal Australian and New Zealand College of Obstetricians and Gynaecologists was conducted between 23 June and 31 July 2009 using an email invitation to proceed to an online questionnaire. Attitudes to abortion; self-reported usual practice of induced abortion. Of 1498 Fellows and trainees invited to complete the questionnaire, 740 (49%) did so. Of these respondents, 632 (85%) stated that they did not hold religious or conscientious views that would make them totally opposed to abortion; 463 of these (73%) reported performing abortion as part of their personal practice, with 204 (44%) doing so only for severe fetal abnormality or serious maternal medical conditions. 108 respondents reported holding views that made them totally opposed to abortion - 60 (56%) opposed it in any situation at all and 48 (44%) opposed it with limited exceptions. Of those opposed, 34 (32%) added comment that they perform abortion for severe fetal abnormality or serious maternal medical conditions, and a further 17 (16%) commented that they refer women requesting abortion in these circumstances to colleagues. Of the respondents not opposed to abortion, 89% supported the availability of induced abortion within the public health system, and half felt that national availability of mifepristone would modify their practice of induced abortion. There was broad support among responding specialist obstetricians and gynaecologists and trainees for the availability of induced abortion in Australia. This study highlights the difficulties of accurately reporting a wide range of views on a contentious issue.
Post-abortion care: a women's health initiative to combat unsafe abortion.

Improving postabortion care can reduce the negative impact of unsafe abortion. Of the 53 million estimated induced abortions occurring annually about two out of five involve unsafe procedures. About one abortion occurs for every three births annually. 96% of abortions in Africa and 85% of abortions in Latin America are unsafe. About 100,000 to 200,000 women die every year from unsafe abortion, or 1 out of 400 women. Family planning is unavailable to over 120 million women in developing countries who desire contraception. Past moral and political controversies divert attention away from death and injury. The international community can take the opportunity to change affairs by adopting a women's health initiative globally. Improvements are needed in quality of care and accessibility of emergency treatment services. Emergency treatment services are usually only available at the tertiary level of care in urban areas. Poor transportation systems limit access. Access is also impaired by women's attitudes toward treatment centers. Availability of services needs to increased through decentralized centers. Clear protocols and comprehensive, systematic training must be accomplished in tandem with improvements in quality. Provision of technology such as manual vacuum aspiration is cost effective and an easy way to improve quality in primary care or outpatient settings. Unsafe abortion is a byproduct of the failure to provide adequate family planning for prevention of unwanted pregnancy. The obstacles, that interfere with provision of family planning to abortion users, should be removed. These obstacles include providers' lack of understanding of women's needs and motivations, separation between abortion and family planning services, misinformation about contraception following abortion, lack of acknowledgement about unsafe abortion, and women's low status. National and international policies also interfere with provision of contraception. Complete reproductive health care is a necessity for improvement in maternal health and mortality.
Clandestine abortions are not necessarily illegal.

PubMed

Cook, R J

1991-01-01

It is common to find the term illegal abortion misused. Often times this misuse is perpetrated by antiabortion advocates who wish to reinforce negative stereotypes and thus apply pressure on doctors to refrain from performing abortions. Until a practitioner is prosecuted and convicted of performing an abortion contrary to the law, the procedure should not be referred to as illegal. Instead the legally neutral term, abortion, should be used instead. This would better serve the interests of women's reproductive health. There is no legal system that makes abortion illegal in all circumstances. For example, abortion is often legal if the life of the mother in danger. This includes a perception on behalf of the practitioner that the women may be suicidal or attempt to terminate the pregnancy by herself. A practitioner performing an abortion in such circumstances is not doing so illegally. The use of the term illegal abortion ignores the fact that in criminal law one is presumed innocent until proven guilty. A prosecutor must prove 1st that an intervention was performed and 2nd that a criminal intent accompanied the intervention. It is this 2nd criterion that is often the hardest to prove, since the practitioner must only testify that the intervention was indicated by legally allowed circumstances to be innocent. The prosecutor must show bad faith in order to gain a justified conviction. Even abortion by unqualified practitioners may not be illegal if doctors refuse to perform the intervention because it is still indicated. Accurate description of abortions would clarify situations in which abortion can be legally provided.

The Commonwealth Regional Health Community Secretariat undertook a study in 1994 to document the magnitude of abortion complications in Commonwealth member countries. The results of the literature review component of that study, and research gaps identified as a result of the review, are presented in this article. The literature review findings indicate a significant public health problem in the region, as measured by a high proportion of incomplete abortion patients among all hospital gynaecology admissions. The most common complications of unsafe abortion seen at health facilities were haemorrhage and sepsis. Studies on the use of manual vacuum aspiration for treating abortion complications found shorter lengths of hospital stay (and thus, lower resource costs) and a reduced need for a repeat evacuation. Very few articles focused exclusively on the cost of treating abortion complications, but authors agreed that it consumes a disproportionate amount of hospital resources. Studies on the role of men in supporting a woman's decision to abort or use contraception were similarly lacking. Articles on contraceptive behaviour and abortion reported that almost all patients suffering from abortion complications had not used an effective, or any, method of contraception prior to becoming pregnant, especially among the adolescent population; studies on post-abortion contraception are virtually nonexistent. Almost all articles on the legal aspect of abortion recommended law reform to reflect a public health, rather than a criminal, orientation. Research needs that were identified include: community-based epidemiological studies; operations research on decentralization of post-abortion care and integration of treatment with post-abortion family planning services; studies on system-wide resource use for treatment of incomplete abortion; qualitative research on the role of males in the decision to terminate pregnancy and use contraception; clinical studies on pain control medications and procedures; and case studies on the provision of safe abortion services where legally allowed.

Since 1969, CDC has conducted abortion surveillance to document the number and characteristics of women obtaining legal induced abortions in the United States. 2007. Each year, CDC requests abortion data from the central health agencies of 52 reporting areas (the 50 states, the District of Columbia, and New York City). This information is provided voluntarily. For 2007, data were received from 49 reporting areas. For the purpose of trend analysis, data were evaluated from the 45 areas that reported data every year during the preceding decade (1998-2007). Abortion rates (number of abortions per 1,000 women) and ratios (number of abortions per 1,000 live births) were calculated using census and natality data, respectively. A total of 827,609 abortions were reported to CDC for 2007. Among the 45 reporting areas that provided data every year during 1998-2007, a total of 810,582 abortions (97.9% of the total) were reported for 2007; the abortion rate was 16.0 abortions per 1,000 women aged 15-44 years, and the abortion ratio was 231 abortions per 1,000 live births. Compared with 2006, the total number and rate of reported abortions decreased 2%, and the abortion ratio decreased 3%. Reported abortion numbers, rates, and ratios were 6%, 7%, and 14% lower, respectively, in 2007 than in 1998. Women aged 20-29 years accounted for 56.9% of all abortions in 2007 and for the majority of abortions during the entire period of analysis (1998-2007). In 2007, women aged 20-29 years also had the highest abortion rates (29.4 abortions per 1,000 women aged 20-24 years and 21.4 abortions per 1,000 women aged 25-29 years). Adolescents aged 15-19 years accounted for 16.5% of all abortions in 2007 and had an abortion rate of 14.5 abortions per 1,000 adolescents aged 15-19 years; women aged ≥35 years accounted for a smaller percentage (12.0%) of abortions and had lower abortion rates (7.7 abortions per 1,000 women aged 35-39 years and 2.6 abortions per 1,000 women aged ≥40 years). During 1998-2007, the abortion rate increased among women aged ≥35 years but decreased among adolescents aged ≤19 years and among women aged 20-29 years. In contrast to the percentage distribution of abortions and abortion rates, abortion ratios were highest at the extremes of reproductive age, both in 2007 and throughout the entire period of analysis. During 1998-2007 abortion ratios decreased among women in all age groups except for those aged <15 years. In 2007, most (62.3%) abortions were performed at ≤8 weeks' gestation, and 91.5% were performed at ≤13 weeks' gestation. Few abortions (7.2%) were performed at 14-20 weeks' gestation, and 1.3% were performed at ≥21 weeks' gestation. During 1998-2007, the percentage of abortions performed at ≤13 weeks' gestation remained stable; however, abortions performed at ≥16 weeks' gestation decreased by 13%-14%, and among the abortions performed at ≤13 weeks' gestation, the percentage performed at ≤6 weeks' gestation increased 65%. In 2007, 78.1% of abortions were performed by curettage at ≤13 weeks' gestation, and 13.1% were performed by early medical abortion (a nonsurgical abortion at ≤8 weeks' gestation); 7.9% of abortions were performed by curettage at >13 weeks' gestation. Among the 62.3% of abortions that were performed at ≤8 weeks' gestation, and thus were eligible for early medical abortion, 20.3% were completed by this method. Deaths of women associated with complications from abortions for 2007 are being investigated under CDC's Pregnancy Mortality Surveillance System. In 2006, the most recent year for which data were available, six women were reported to have died as a result of complications from known legal induced abortions. No reported deaths were associated with known illegal induced abortions. Among the 45 areas that reported data every year during 1998-2007, the total number, rate, and ratio of reported abortions decreased during 2006-2007. This decrease reversed the increase in reported abortion numbers and rates that occurred during 2005-2006; however, reported abortion numbers and rates for 2007 still were higher than they had been previously in 2005. In 2006, as in previous years, reported deaths related to abortion were rare. Abortion surveillance in the United States continues to provide the data needed to examine trends in the number and characteristics of women obtaining abortions. Policymakers and program planners can use these data to guide and evaluate efforts to prevent unintended pregnancies.

CONTEXT Abortion availability and accessibility vary by state. Especially in areas where services are restricted or limited, some women travel to obtain abortion services in other states. Little is known about the experience of travel to obtain abortion. METHODS In January and February 2015, in-depth interviews were conducted with 29 patients seeking abortion services at six facilities in Michigan and New Mexico. Eligible women were 18 or older, spoke English, and had traveled either across state lines or more than 100 miles within the state. Respondents were asked to describe their experience from pregnancy discovery to the day of the abortion procedure. Barriers to accessing abortion care and consequences of these barriers were identified through inductive and deductive analysis. RESULTS Respondents described 15 barriers to abortion care while traveling to obtain services, and three major consequences of experiencing those barriers. Barriers were grouped into five categories: travel-related logistical issues, system navigation issues, limited clinic options, financial issues, and state or clinic restrictions. Consequences were delays in care, negative mental health impacts and considering self-induction. The experience of barriers complicated the process of obtaining an abortion, but the effect of any individual barrier was unclear. Instead, the experience of multiple barriers appeared to have a compounding effect, resulting in negative consequences for women traveling for abortion. CONCLUSION The amalgamation of barriers to abortion care experienced simultaneously can have significant consequences for patients. PMID:28394463

Unsafe abortion is affecting a lot, in health, socio-economic and health care cost of many countries. Despite invention of simple technology and scientifically approved safe abortion methods, women and girls are still using unsafe abortion practices. Since 2002, Nepal has achieved remarkable progress in developing policies, guidelines, task shifting, training human resources and increasing access to services. However, more than half of abortion in Nepal are performed clandestinely by untrained or unapproved providers or induced by pregnant woman herself. Knowledge on legalization and availability of safe abortion service among women is still very poor. Stigma on abortion still persists among community people, service providers, managers, and policy makers. Access to safe abortion, especially in remote and rural areas, is still far behind as compared to their peers from urban areas. The existing law is not revised in the spirit of current Constitution of Nepal and rights-based approach. The existence of abortion stigma and the shifting of the government structure from unitary system to federalism in absence of a complete clarity on how the safe abortion service gets integrated into the local government structure might create challenge to sustain existing developments. There is, therefore, a need for all stakeholders to make a lot of efforts and allocate adequate resources to sustain current achievements and ensure improvements in creating a supportive social environment for women and girls so that they will be able to make informed decisions and access to safe abortion service in any circumstances.

To report our experience on the value of transcatheter arterial embolization (TAE) or transcatheter arterial chemoembolization (TACE) for the uterus-preserving management of retained placenta accreta with marked vascularity after abortion or delivery. Thirty-eight consecutive women with retained placenta accreta were retrospectively analyzed over a 5-year period. When elevated levels of serum β-hCG (> 25 mIU/mL) were detected, TACE with dactinomycin was chosen for devascularization along with cytotoxic effects on active trophoblasts; in contrast, if the serum β-hCG level was low (≤ 25 mIU/mL), TAE was chosen. After confirming devascularization, the additional need for hysteroscopic resection and systemic methotrexate administration was individually determined. The most frequent sign and symptom in the abortion group was significant hemorrhaging, while a hypervascular mass detected at a regular check-up was the most frequent in the delivery group. The median time elapsed between abortion and endovascular management was 36 days, and the median time elapsed after delivery was 31.5 days. TACE was performed more frequently than TAE in the abortion group, while TAE was the more frequent procedure in the delivery group. In 10 and 11 cases, after abortion and delivery, respectively, hysteroscopic resection was performed. Systemic methotrexate administration was additionally done in three and one cases after abortion and delivery, respectively. Uterine preservation was achieved in all cases. This case series emphasizes that endovascular embolization is an effective key intervention with or without additional therapies for uterus-preserving management of retained placenta accreta with marked vascularity after abortion or delivery.

In a well-established murine abortion model, stress is thought to trigger fetal rejection by inducing a proinflammatory immune response via substance P (SP), being tumour necrosis factor (TNF)-alpha-producing CD8+ T cells involved. Interestingly, the SP metabolite SP5-11 also binds to SP receptors and mediates SP-like effects on immune cells at sites of inflammation. No data were available regarding the effects of SP5-11 on pregnancy outcome in the CBA/J x DBA/2J abortion-prone combination. We investigated the influence of SP5-11 in contrast to stress or SP on the abortion rate and the cytokine production by lymphocytes as well as on the levels of CD8+ T cells. Stress and SP boosted the abortion rate and increased the percentage of type 1 [TNF-alpha, interferon-gamma, interleukin (IL)-12] and type 2 (IL-4 and IL-10) cytokine-producing lymphocytes in blood and decidua, predominantly CD8+ T cells. Interestingly, SP5-11 did not significantly affect the abortion rate or cytokine production in the decidua, while increasing the Th1 and Th2 cytokine production systemically. Our data suggest that stress and SP induce abortion by augmenting the local levels of TNF-alpha, which seems therefore to be a potent trigger of miscarriage. On the contrary, the SP metabolite SP5-11 only affects the systemic cytokine production without boosting the abortion rate in this experimental model.

The implementation of a pre- and post-abortion health care strategy, adopted in 2004 in Uruguay within a restrictive legal context prior to the decriminalization of abortion in 2012, opened a window of opportunity to link women facing unwanted pregnancies and abortion to health services in order to prevent unsafe abortion practices. This article looks into the tensions generated by the change of focus from maternal-child health to health and sexual and reproductive rights, and how those tensions operate. Using semi-structured interviews and focus groups, the practices and perception and assessment frameworks of professionals in their care of women facing unwanted pregnancy and abortion in the National Integrated Health System in Montevideo are analyzed. The results offer insights into some of the barriers and difficulties that can currently be observed in the implementation of the new law.

We discuss the history of the World Health Organization's (WHO's) development of guidelines for governments on providing safe abortion services, which WHO published as Safe Abortion: Technical and Policy Guidance for Health Systems in 2003 and updated in 2012. We show how the recognition of the devastating impact of unsafe abortion on women's health and survival, the impetus of the International Conference on Population and Development and its five-year follow-up, and WHO's progressive leadership at the end of the century enabled the organization to elaborate guidance on providing safe abortion services. Guideline formulation involved extensive review of published evidence, an international technical expert meeting to review the draft document, and a protracted in-house review by senior WHO management.
Was the French clinical surveillance system of bovine brucellosis influenced by the occurrence and surveillance of other abortive diseases?

The bovine brucellosis clinical surveillance system implemented in France aims to detect early any case of bovine brucellosis, a disease of which the country has been declared free since 2005. It relies on the mandatory notification of every bovine abortion. Following the spread of the Schmallenberg virus (SBV) in France in 2012 and 2013, and the implementation in 2012 of a clinical surveillance programme of Q fever based on abortion notifications in ten pilot départements, our objective was to study whether these two events influenced the brucellosis clinical surveillance system. The proportion of notifying farmers was analyzed over each semester from June 1, 2009 to June 30, 2013 according to the size and production type of herds, SBV status of départements and the implementation of the Q fever surveillance. Our analysis showed a slight increase in the proportion of notifying farmers as départements became infected by SBV, and after the implementation of Q fever surveillance (during the first semester of 2013). These variations might be explained by an increase in abortion occurrence (congenital deformities in newborns, due to SBV) and/or by an increase in farmers' and veterinarians' awareness (due to the spread of SBV and the implementation of the Q fever surveillance). These results highlight the difficulties in interpreting variations in the proportion of notifying farmers as a consequence of an increase in abortion occurrence. As bovine abortion surveillance can play an important role in the early warning for several diseases, there is a need to explore other ways to monitor abortions in cattle, such as syndromic surveillance using the dates of artificial insemination or calving data.

Open-Loop Pitch Table Optimization for the Maximum Dynamic Pressure Orion Abort Flight Test

NASA Technical Reports Server (NTRS)

Stillwater, Ryan A.

2009-01-01

NASA has scheduled the retirement of the space shuttle orbiter fleet at the end of 2010. The Constellation program was created to develop the next generation of human spaceflight vehicles and launch vehicles, known as Orion and Ares respectively. The Orion vehicle is a return to the capsule configuration that was used in the Mercury, Gemini, and Apollo programs. This configuration allows for the inclusion of an abort system that safely removes the capsule from the booster in the event of a failure on launch. The Flight Test Office at NASA's Dryden Flight Research Center has been tasked with the flight testing of the abort system to ensure proper functionality and safety. The abort system will be tested in various scenarios to approximate the conditions encountered during an actual Orion launch. Every abort will have a closed-loop controller with an open-loop backup that will direct the vehicle during the abort. In order to provide the best fit for the desired total angle of attack profile with the open-loop pitch table, the table is tuned using simulated abort trajectories. A pitch table optimization program was created to tune the trajectories in an automated fashion. The program development was divided into three phases. Phase 1 used only the simulated nominal run to tune the open-loop pitch table. Phase 2 used the simulated nominal and three simulated off nominal runs to tune the open-loop pitch table. Phase 3 used the simulated nominal and sixteen simulated off nominal runs to tune the open-loop pitch table. The optimization program allowed for a quicker and more accurate fit to the desired profile as well as allowing for expanded resolution of the pitch table.
Decriminalization and Women’s Access to Abortion in Australia

PubMed Central

2017-01-01

Abstract This article considers the relationship between the decriminalization of abortion and women’s access to abortion services. It focuses on the four Australian jurisdictions which are, with Canada, the only jurisdictions in the world where abortion has been removed from the criminal law. This paper draws on documentary evidence and an oral history project to give a “before and after” account of each jurisdiction. The paper assumes that the meaning and impact of decriminalization must be assessed in each local context. Understanding the conditions that shape access must incorporate analysis of the broader social, political and economic environment as well as the law. The article finds that decriminalization does not necessarily deliver any improvement in women’s access to abortion, at least in the short term. Further, it is not inconsistent with the neoliberal policy environment that characterizes the provision of abortion care in Australia, where most abortions are provided through the private sector at financial cost to women. If all women are to enjoy their human rights to full reproductive health care, the public health system must take responsibility for the adequate provision of abortion services; ongoing and vigilant activism is central if this is to be achieved.

2007-01-01

An important element in the design of NASA's Crew Exploration Vehicle (CEV) is the consideration given to crew safety during various ascent phase failure scenarios. To help ensure crew safety during this critical and dynamic flight phase, the CEV requirements specify that an abort capability must be continuously available from lift-off through orbit insertion. To address this requirement, various CEV ascent abort modes are analyzed using 3-DOF (Degree Of Freedom) and 6-DOF simulations. The analysis involves an evaluation of the feasibility and survivability of each abort mode and an assessment of the abort mode coverage using the current baseline vehicle design. Factors such as abort system performance, crew load limits, thermal environments, crew recovery, and vehicle element disposal are investigated to determine if the current vehicle requirements are appropriate and achievable. Sensitivity studies and design trades are also completed so that more informed decisions can be made regarding the vehicle design. An overview of the CEV ascent abort modes is presented along with the driving requirements for abort scenarios. The results of the analysis completed as part of the requirements validation process are then discussed. Finally, the conclusions of the study are presented, and future analysis tasks are recommended.
Shuttle Abort Flight Management (SAFM) - Application Overview

One of the most demanding tasks that must be performed by the Space Shuttle flight crew is the process of determining whether, when and where to abort the vehicle should engine or system failures occur during ascent or entry. Current Shuttle abort procedures involve paging through complicated paper checklists to decide on the type of abort and where to abort. Additional checklists then lead the crew through a series of actions to execute the desired abort. This process is even more difficult and time consuming in the absence of ground communications since the ground flight controllers have the analysis tools and information that is currently not available in the Shuttle cockpit. Crew workload specifically abort procedures will be greatly simplified with the implementation of the Space Shuttle Cockpit Avionics Upgrade (CAU) project. The intent of CAU is to maximize crew situational awareness and reduce flight workload thru enhanced controls and displays, and onboard abort assessment and determination capability. SAFM was developed to help satisfy the CAU objectives by providing the crew with dynamic information about the capability of the vehicle to perform a variety of abort options during ascent and entry. This paper- presents an overview of the SAFM application. As shown in Figure 1, SAFM processes the vehicle navigation state and other guidance information to provide the CAU displays with evaluations of abort options, as well as landing site recommendations. This is accomplished by three main SAFM components: the Sequencer Executive, the Powered Flight Function, and the Glided Flight Function, The Sequencer Executive dispatches the Powered and Glided Flight Functions to evaluate the vehicle's capability to execute the current mission (or current abort), as well as more than IS hypothetical abort options or scenarios. Scenarios are sequenced and evaluated throughout powered and glided flight. Abort scenarios evaluated include Abort to Orbit (ATO), Transatlantic Abort Landing (TAL), East Coast Abort Landing (ECAL) and Return to Launch Site (RTLS). Sequential and simultaneous engine failures are assessed and landing footprint information is provided during actual entry scenarios as well as hypothetical "loss of thrust now" scenarios during ascent.

In settings where abortion is legally restricted, or permitted but not widely accessible, women face significant barriers to abortion access, sometimes leading them to seek services outside legal facilities. The advent of medication abortion has further increased the prevalence of informal sector abortion. This study investigates the reasons for attempting self-induction, methods used, complications, and sources of information about informal sector abortion, and tests a specific recruitment method which could lead to improved estimates of informal sector abortion prevalence among an at-risk population. We recruited women who have sought informal sector abortion services in Cape Town, South Africa using respondent driven sampling (RDS). An initial seed recruiter was responsible for initiating recruitment using a structured coupon system. Participants completed face-to-face questionnaires, which included information about demographics, informal sector abortion seeking, and safe abortion access needs. We enrolled 42 women, nearly one-third of whom reported they were sex workers. Thirty-four women (81%) reported having had one informal sector abortion within the past 5 years, 14% reported having had two, and 5% reported having had three. These women consumed home remedies, herbal mixtures from traditional healers, or tablets from an unregistered provider. Twelve sought additional care for potential warning signs of complications. Privacy and fear of mistreatment at public sector facilities were among the main reported reasons for attempting informal sector abortion. Most women (67%) cited other community members as their source of information about informal sector abortion; posted signs and fliers in public spaces also served as an important source of information. Women are attempting informal sector abortion because they seek privacy and fear mistreatment and stigma in health facilities. Some were unaware how or where to seek formal sector services, or believed the cost was too high. Many informal methods are ineffective and unsafe, leading to potential warning signs of complications and continued pregnancy. Sex workers may be at particular risk of unsafe abortion. Based on these results, it is essential that future studies sample women outside of the formal health sector. The use of innovative sampling methods would greatly improve our knowledge about informal sector abortion in South Africa.

The objectives of this study were (1) to estimate the frequency and dynamics of bovine abortion syndrome; (2) to identify groups of cows affected by abortion; and (3) to assess the characteristics of herd management and lactation associated with abortion rates. The study was performed using farmers' historical records for 77 dairy herds in the south of Chile (Bio-Bio, Los Lagos and Los Ríos Regions) collected between 2001 and 2005. These records included 44,959 lactations from 20,977 cows. In addition, farm management practices were assessed through a questionnaire involving 127 herds. The herds were selected according to the farmers' willingness to participate and the existence of high-quality electronic records assessed by the practitioners advising the farms. The frequency distribution of observed, inferred and general abortions was estimated by the incidence rate (IR). A hierarchical logistic regression analysis with random intercept was performed to assess the association between herd management and lactation characteristics and the occurrence of abortion. An IR of 1.74 per 100 cow-months at risk was estimated. General abortions were highest in first-parity cows (IR: 1.85 per 100 cow-months at risk). Abortion cases inferred from individual records were most frequent in the first trimester of gestation and decreased over time, whereas observed abortions increased in accordance with gestation time. The period of highest risk for abortion was around 82 days of gestation. Management practices such as a tap drinking system for cows, a closed herd, vaccination against leptospirosis, exclusive use of pasture for cows, animal density, the time that a calf stays with its dam and breed type were associated with the risk of abortion. The results of this study demonstrate that there is a large underestimation of abortion rates when only farmers' abortion records are analysed, and there are several factors associated with the risk of abortion.

SpaceX and Boeing have been selected to develop and operate crew vehicles to transport astronauts to and from the International Space Station. Their design work is to be analyzed to ensure that they are meeting all of the safety and operational requirements put forth by NASA. Throughout my time here, I worked familiarized myself with the SpaceX Dragon Abort system, as well as the NASA Human-Systems Integration Requirements (HSIR). This included understanding the different abort scenarios, and how each one could potentially impact the astronaut crew. In addition, I familiarized myself with the simulation developed my NASA to test and analyze the Guidance Navigation and Control (GN&C) systems developed by SpaceX and Boeing.

Concern has been expressed about potential harm to women's mental health in association with having an induced abortion, but it remains unclear whether induced abortion is associated with an increased risk of subsequent psychiatric problems. We conducted a population-based cohort study that involved linking information from the Danish Civil Registration system to the Danish Psychiatric Central Register and the Danish National Register of Patients. The information consisted of data for girls and women with no record of mental disorders during the 1995-2007 period who had a first-trimester induced abortion or a first childbirth during that period. We estimated the rates of first-time psychiatric contact (an inpatient admission or outpatient visit) for any type of mental disorder within the 12 months after the abortion or childbirth as compared with the 9-month period preceding the event. The incidence rates of first psychiatric contact per 1000 person-years among girls and women who had a first abortion were 14.6 (95% confidence interval [CI], 13.7 to 15.6) before abortion and 15.2 (95% CI, 14.4 to 16.1) after abortion. The corresponding rates among girls and women who had a first childbirth were 3.9 (95% CI, 3.7 to 4.2) before delivery and 6.7 (95% CI, 6.4 to 7.0) post partum. The relative risk of a psychiatric contact did not differ significantly after abortion as compared with before abortion (P = 0.19) but did increase after childbirth as compared with before childbirth (P < 0.001). The finding that the incidence rate of psychiatric contact was similar before and after a first-trimester abortion does not support the hypothesis that there is an increased risk of mental disorders after a first-trimester induced abortion.

Background Safe and legal abortions are rarely practiced in the public health sector in Kenya, and rates of maternal mortality and morbidity from unsafe abortion is high. Little is known about women’s experiences seeking and accessing abortion in informal settlements in Nairobi, Kenya. Methods Seven focus group discussions were conducted with a total of 71 women and girls recruited from an informal settlement in Nairobi. The interview guide explored participants’ perceptions of unplanned pregnancy, abortion, and access to sexual and reproductive health information in their community. Thematic analysis of the focus group transcripts was conducted using MAX QDA Release 12. Results Participants described a variety of factors that influence women’s experiences with abortion in their communities. According to participants, limited knowledge of sexual and reproductive health information and lack of access to contraception led to unplanned pregnancy among women in their community. Participants cited stigma and loss of opportunities that women with unplanned pregnancies face as the primary reasons why women seek abortions. Participants articulated stigma as the predominant barrier women in their communities face to safe abortion. Other barriers, which were often interrelated to stigma, included lack of education about safe methods of abortion, perceived illegality of abortion, as well as limited access to services, fear of mistreatment, and mistrust of health providers and facilities. Conclusions Women in informal settlements in Nairobi, Kenya face substantial barriers to regulating their fertility and lack access to safe abortion. Policy makers and reproductive health advocates should support programs that employ harm reduction strategies and increase women’s knowledge of and access to medication abortion outside the formal healthcare system.

Abortion availability and accessibility vary by state. Especially in areas where services are restricted or limited, some women travel to obtain abortion services in other states. Little is known about the experience of travel to obtain abortion. In January and February 2015, in-depth interviews were conducted with 29 patients seeking abortion services at six facilities in Michigan and New Mexico. Eligible women were 18 or older, spoke English, and had traveled either across state lines or more than 100 miles within the state. Respondents were asked to describe their experience from pregnancy discovery to the day of the abortion procedure. Barriers to accessing abortion care and consequences of these barriers were identified through inductive and deductive analysis. Respondents described 15 barriers to abortion care while traveling to obtain services, and three major consequences of experiencing those barriers. Barriers were grouped into five categories: travel-related logistical issues, system navigation issues, limited clinic options, financial issues, and state or clinic restrictions. Consequences were delays in care, negative mental health impacts and considering self-induction. The experience of barriers complicated the process of obtaining an abortion, but the effect of any individual barrier was unclear. Instead, the experience of multiple barriers appeared to have a compounding effect, resulting in negative consequences for women traveling for abortion. The amalgamation of barriers to abortion care experienced simultaneously can have significant consequences for patients. © 2017 The Authors.

Background Unsafe abortion contributes to a significant portion of maternal mortality in India. Access to safe abortion care is known to reduce maternal mortality. Availability and distribution of abortion care facilities can influence women's access to these services, especially in rural areas. Objectives To assess the availability and distribution of abortion care at facilities providing childbirth care in three districts of Madhya Pradesh (MP) province of India. Design Three socio demographically heterogeneous districts of MP were selected for this study. Facilities conducting at least 10 deliveries a month were surveyed to assess availability and provision of abortion services using UN signal functions for emergency obstetric care. Geographical Information System was used for visualisation of the distribution of facilities. Results The three districts had 99 facilities that conducted >10 deliveries a month: 74 in public and 25 in private sector. Overall, 48% of facilities reported an ability to provide safe surgical abortion service. Of public centres, 32% reported the ability compared to 100% among private centres while 18% of public centres and 77% of private centres had performed an abortion in the last 3 months. The availability of abortion services was higher at higher facility levels with better equipped and skilled personnel availability, in urban areas and in private sector facilities. Conclusions Findings showed that availability of safe abortion care is limited especially in rural areas. More emphasis on providing safe abortion services, particularly at primary care level, is important to more significantly dent maternal mortality in India. PMID:25797220
Optimal control theory determination of feasible return-to-launch-site aborts for the HL-20 Personnel Launch System vehicle

Dutton, Kevin E.

1994-01-01

The personnel launch system (PLS) being studied by NASA is a system to complement the space shuttle and provide alternative access to space. The PLS consists of a manned spacecraft launched by an expendable launch vehicle (ELV). A candidate for the manned spacecraft is the HL-20 lifting body. In the event of an ELV malfunction during the initial portion of the ascent trajectory, the HL-20 will separate from the rocket and perform an unpowered return to launch site (RTLS) abort. This work details an investigation, using optimal control theory, of the RTLS abort scenario. The objective of the optimization was to maximize final altitude. With final altitude as the cost function, the feasibility of an RTLS abort at different times during the ascent was determined. The method of differential inclusions was used to determine the optimal state trajectories, and the optimal controls were then calculated from the optimal states and state rates.

CAPE CANAVERAL, Fla. – Inside the Launch Abort System Facility at NASA’s Kennedy Space Center in Florida, the launch abort system, or LAS, components are horizontally stacked as processing continues for the Orion Exploration Flight Test-1 mission. Components of the LAS are the launch abort motor, the attitude control motor, the jettison motor and the fairing. Orion is the exploration spacecraft designed to carry crews to space beyond low Earth orbit. It will provide emergency abort capability, sustain the crew during the space travel and provide safe re-entry from deep space return velocities. The LAS is designed to safely pull the Orion crew module away from the launch vehicle in the event of an emergency on the launch pad or during the initial ascent of NASA’s Space Launch System, or SLS, rocket. Orion’s first unpiloted test flight is scheduled to launch in 2014 atop a Delta IV rocket. A second uncrewed flight test is scheduled for 2017 on the SLS rocket.

[Abortion in Colombia. Medical, legal and socioeconomic aspects].

Umaña, A O

1973-01-01

Abortion is a social problem and criminal sanctions are very ineffective in limiting it and are seldom applied (133 legal actions vs. 65,600 cases of induced abortion in 1965). Abortion is a social disease, as are prostitution, juvenile delinquency, drug abuse, and so far has been an insoluble problem. Colombian laws should be modified to reflect reality. Sex education must be emphasized, because ignorance is one of the main causes of abortion. Leniency should be applied toward women who cooperate with the authorities in identifying the person who performed an abortion. Legalization of abortion and enforcement of strict laws against it are considered as possible solutions, but both are rejected. The former is regarded as morally unacceptable and as imposing an excessive burden on scarce health services, the latter as even worse, imposing an equivalent burden on the court system, without s olving either health or social problems. The best and probably only solution is to improve education in family planning, to promote knowledge and motivation to enable the population to make sound and responsible decisions.
Contraceptive use among migrant women with a history of induced abortion in Finland.

Women's contraceptive choices may change after an induced abortion, due to contraceptive counselling or a behavioural change prompted by the experience. The effect may vary between women; sociocultural background, for example, may affect their subsequent reproductive choices. We examined whether women's current contraceptive use was differently associated with a history of induced abortion among immigrant groups in Finland (Russian, Kurdish and Somali) and the general Finnish population. We analysed data from two surveys, the Migrant Health and Wellbeing study and the Health 2011 study, linked to the Finnish register of induced abortions. Propensity score weighted logistic regression was used to analyse the data. The likelihood of using contraceptives after an abortion varied depending on women's sociocultural background. A history of induced abortion increased contraceptive use among all groups, except Russian women, in whom there was no effect. The effect was particularly strong for Kurdish women. Sociocultural background was an important determinant of post-abortion contraceptive use. Some immigrants may struggle to navigate the Finnish health care system due to language or literacy issues. Attention should be paid to improving access to family planning among these groups.
Fail-safe system for activity cooled supersonic and hypersonic aircraft. [using liquid hydrogen fuel

Jones, R. A.; Braswell, D. O.; Richie, C. B.

1975-01-01

A fail-safe-system concept was studied as an alternative to a redundant active cooling system for supersonic and hypersonic aircraft which use the heat sink of liquid-hydrogen fuel for cooling the aircraft structure. This concept consists of an abort maneuver by the aircraft and a passive thermal protection system (TPS) for the aircraft skin. The abort manuever provides a low-heat-load descent from normal cruise speed to a lower speed at which cooling is unnecessary, and the passive TPS allows the aircraft skin to absorb the abort heat load without exceeding critical skin temperature. On the basis of results obtained, it appears that this fail-safe-system concept warrants further consideration, inasmuch as a fail-safe system could possibly replace a redundant active cooling system with no increase in weight and would offer other potential advantages.

Abortion and subsequent excretion of chlamydiae from the reproductive tract of sheep during estrus.

PubMed Central

Papp, J R; Shewen, P E; Gartley, C J

1994-01-01

Chlamydia psittaci serovar 1 infection in pregnant sheep typically causes abortion or the birth of weak lambs. Eight sheep that experienced chlamydia-induced abortion during their first pregnancy were successfully rebred yearly for the past 2 years. Chlamydia-specific lipopolysaccharide was detectable for approximately 3 weeks in vaginal swabs taken from the experimentally infected sheep following abortion. There was no evidence of chlamydiae in vaginal, placental, or neonatal samples obtained immediately after each subsequent successful pregnancy. Sera collected from the experimentally infected sheep had persistent, high antibody levels to C. psittaci, suggesting continued exposure of the immune system to the organism. Examination of vaginal specimens obtained during various stages of the estrus cycle revealed detectable levels of chlamydiae only when the animal was near ovulation. Chlamydiae were not detected in swabs from sheep that did not experience abortion. Enhanced chlamydial excretion during the periovulation period of sheep may provide sufficient stimulation of the immune system to account for the persistent antibody response. Furthermore, the association between estrus and chlamydial shedding has important implications for transmission of infection to other ewes during breeding. PMID:8063395

We discuss the history of the World Health Organization’s (WHO’s) development of guidelines for governments on providing safe abortion services, which WHO published as Safe Abortion: Technical and Policy Guidance for Health Systems in 2003 and updated in 2012. We show how the recognition of the devastating impact of unsafe abortion on women’s health and survival, the impetus of the International Conference on Population and Development and its five-year follow-up, and WHO’s progressive leadership at the end of the century enabled the organization to elaborate guidance on providing safe abortion services. Guideline formulation involved extensive review of published evidence, an international technical expert meeting to review the draft document, and a protracted in-house review by senior WHO management.

Barriers and facilitators in the provision of post-abortion care at district level in central Uganda – a qualitative study focusing on task sharing between physicians and midwives

PubMed Central

2014-01-01

Background Abortion is restricted in Uganda, and poor access to contraceptive methods result in unwanted pregnancies. This leaves women no other choice than unsafe abortion, thus placing a great burden on the Ugandan health system and making unsafe abortion one of the major contributors to maternal mortality and morbidity in Uganda. The existing sexual and reproductive health policy in Uganda supports the sharing of tasks in post-abortion care. This task sharing is taking place as a pragmatic response to the increased workload. This study aims to explore physicians’ and midwives’ perception of post-abortion care with regard to professional competences, methods, contraceptive counselling and task shifting/sharing in post-abortion care. Methods In-depth interviews (n = 27) with health care providers of post-abortion care were conducted in seven health facilities in the Central Region of Uganda. The data were organized using thematic analysis with an inductive approach. Results Post-abortion care was perceived as necessary, albeit controversial and sometimes difficult to provide. Together with poor conditions post-abortion care provoked frustration especially among midwives. Task sharing was generally taking place and midwives were identified as the main providers, although they would rarely have the proper training in post-abortion care. Additionally, midwives were sometimes forced to provide services outside their defined task area, due to the absence of doctors. Different uterine evacuation skills were recognized although few providers knew of misoprostol as a method for post-abortion care. An overall need for further training in post-abortion care was identified. Conclusions Task sharing is taking place, but providers lack the relevant skills for the provision of quality care. For post-abortion care to improve, task sharing needs to be scaled up and in-service training for both doctors and midwives needs to be provided. Post-abortion care should further be included in the educational curricula of nurses and midwives. Scaled-up task sharing in post-abortion care, along with misoprostol use for uterine evacuation would provide a systematic approach to improving the quality of care and accessibility of services, with the aim of reducing abortion-related mortality and morbidity in Uganda.

Since 1969, CDC has conducted abortion surveillance to document the number and characteristics of women obtaining legal induced abortions in the United States. 2013. Each year, CDC requests abortion data from the central health agencies of 52 reporting areas (the 50 states, the District of Columbia, and New York City). The reporting areas provide this information voluntarily. For 2013, data were received from 49 reporting areas. For trend analysis, abortion data were evaluated from 47 areas that reported data every year during 2004-2013. Census and natality data, respectively, were used to calculate abortion rates (number of abortions per 1,000 women) and ratios (number of abortions per 1,000 live births). A total of 664,435 abortions were reported to CDC for 2013. Of these abortions, 98.2% were from the 47 reporting areas that provided data every year during 2004-2013. Among these 47 reporting areas, the abortion rate for 2013 was 12.5 abortions per 1,000 women aged 15-44 years, and the abortion ratio was 200 abortions per 1,000 live births. From 2012 to 2013, the total number, rate, and ratio of reported abortions decreased 5%. From 2004 to 2013, the total number, rate, and ratio of reported abortions decreased 20%, 21%, and 17%, respectively. In 2013, all three measures reached their lowest level for the entire period of analysis (2004-2013). In 2013 and throughout the period of analysis, women in their 20s accounted for the majority of abortions and had the highest abortion rates; women in their 30s and older accounted for a much smaller percentage of abortions and had lower abortion rates. In 2013, women aged 20-24 and 25-29 years accounted for 32.7% and 25.9% of all abortions, respectively, and had abortion rates of 21.8 and 18.2 abortions per 1,000 women aged 20-24 and 25-29 years, respectively. In contrast, women aged 30-34, 35-39, and ≥40 years accounted for 16.8%, 9.2%, and 3.6% of all abortions, respectively, and had abortion rates of 11.8, 7.0, and 2.5 abortions per 1,000 women aged 30-34 years, 35-39 years, and ≥40 years, respectively. During 2004-2013, the decrease in abortion rates among adult women aged 20-39 years ranged from 8% to 27% across these age groups, whereas the abortion rate was stable for women aged ≥40 years. In 2013, adolescents aged <15 and 15-19 years accounted for 0.3% and 11.4% of all abortions, respectively, and had abortion rates of 0.6 and 8.2 abortions per 1,000 adolescents aged <15 and 15-19 years, respectively. From 2004 to 2013, the percentage of abortions accounted for by adolescents aged 15-19 years decreased 31% and their abortion rate decreased 46%. These decreases were greater than the decreases for women in any older age group. In contrast to the percentage distribution of abortions and abortion rates by age, abortion ratios in 2013 and throughout the entire period of analysis were highest among adolescents and lowest among women aged 30-39 years. Abortion ratios decreased from 2004 to 2013 for women in all age groups, except for adolescents aged <15 years. In 2013, the majority (66.0%) of abortions were performed by ≤8 weeks' gestation, and nearly all (91.6%) were performed by ≤13 weeks' gestation. Few abortions were performed between 14 and 20 weeks' gestation (7.1%) or at ≥21 weeks' gestation (1.3%). From 2004 to 2013, the percentage of all abortions performed at ≤13 weeks' gestation remained consistently high (≥91.5%) and among those performed at ≤13 weeks' gestation, the percentage performed at ≤6 weeks' gestation increased 16%. In 2013, among the 43 reporting areas that included medical (nonsurgical) abortion on their reporting form, a total of 67.9% of abortions were performed by curettage at ≤13 weeks' gestation, 22.2% were performed by early medical abortion (a nonsurgical abortion at ≤8 weeks' gestation), and 8.6% were performed by curettage at >13 weeks' gestation; all other methods were uncommon. Among abortions performed at ≤8 weeks' gestation that were eligible for early medical abortion on the basis of gestational age, 32.8% were completed by this method. From 2012 to 2013, the percentage of abortions reported as early medical abortions increased 5%. Deaths of women associated with complications from abortion for 2013 are being investigated as part of CDC's Pregnancy Mortality Surveillance System. In 2012, the most recent year for which data were available, four women were identified to have died as a result of complications from known legal induced abortion. No reported deaths were associated with known illegal induced abortion. Among the 47 areas that reported data every year during 2004-2013, the decreases in the total number, rate, and ratio of reported abortions that occurred during 2009-2012 continued from 2012 to 2013, resulting in historic lows for all three measures of abortion. The data in this report can help program planners and policymakers identify groups of women with highest rates of abortion. Unintended pregnancy is the major contributor to abortion. Increasing access to and use of contraception, including the most effective methods, can reduce unintended pregnancies and further reduce the number of abortions performed in the United States.

Census and natality data, respectively, were used to calculate abortion rates (number of abortions per 1,000 women) and ratios (number of abortions per 1,000 live births). A total of 699,202 abortions were reported to CDC for 2012. Of these abortions, 98.4% were from the 47 reporting areas that provided data every year during 2003-2012. Among these same 47 reporting areas, the abortion rate for 2012 was 13.2 abortions per 1,000 women aged 15-44 years, and the abortion ratio was 210 abortions per 1,000 live births. From 2011 to 2012, the total number and ratio of reported abortions decreased 4% and the abortion rate decreased 5%. From 2003 to 2012, the total number, rate, and ratio of reported abortions decreased 17%, 18%, and 14%, respectively, and reached their lowest level in 2012 for the entire period of analysis (2003-2012). In 2012 and throughout the period of analysis, women in their 20s accounted for the majority of abortions and had the highest abortion rates; women in their 30s and older accounted for a much smaller percentage of abortions and had lower abortion rates. In 2012, women aged 20-24 and 25-29 years accounted for 32.8% and 25.4% of all abortions, respectively, and had abortion rates of 23.3 and 18.9 abortions per 1,000 women aged 20-24 and 25-29 years, respectively. In contrast, women aged 30-34, 35-39, and ≥40 years accounted for 16.4%, 9.1%, and 3.7% of all abortions, respectively, and had abortion rates of 12.4, 7.3, and 2.8 abortions per 1,000 women aged 30-34 years, 35-39 years, and ≥40 years, respectively. Throughout the period of analysis, abortion rates decreased among women aged 20-24, 25-29, and 30-34 years by 24%, 18%, and 10%, respectively, whereas they increased among women aged ≥40 years by 8%. In 2012, adolescents aged <15 and 15-19 years accounted for 0.4% and 12.2% of all abortions, respectively, and had abortion rates of 0.8 and 9.2 abortions per 1,000 adolescents aged <15 and 15-19 years, respectively. From 2003 to 2012, the percentage of abortions accounted for by adolescents aged 15-19 years decreased 27% and their abortion rate decreased 40%. These decreases were greater than the decreases for women in any older age group. In contrast to the percentage distribution of abortions and abortion rates by age, abortion ratios in 2012 and throughout the entire period of analysis were highest among adolescents aged ≤19 years and lowest among women aged 30-39 years. Abortion ratios decreased from 2003 to 2012 for women in all age groups. In 2012, the majority (65.8%) of abortions were performed by ≤8 weeks' gestation, and nearly all (91.4%) were performed by ≤13 weeks' gestation. Few abortions (7.2%) were performed between 14-20 weeks' gestation or at ≥21 weeks' gestation (1.3%). From 2003 to 2012, the percentage of all abortions performed at ≤8 weeks' gestation increased 7%; the percentage performed at >13 weeks remained consistently low (≤9.0%). In 2012, among the 40 reporting areas that included medical (nonsurgical) abortion on their reporting form, a total of 69.4% of abortions were performed by curettage at ≤13 weeks' gestation, 20.8% were performed by early medical abortion (a nonsurgical abortion at ≤8 weeks' gestation), and 8.7% were performed by curettage at >13 weeks' gestation; all other methods were uncommon. Among abortions performed at ≤8 weeks' gestation that were eligible on the basis of gestational age for early medical abortion, 30.8% were completed by this method. The percentage of abortions reported as early medical abortions increased 10% from 2011 to 2012. Deaths of women associated with complications from abortions for 2012 are being investigated as part of CDC's Pregnancy Mortality Surveillance System. In 2011, the most recent year for which data were available, two women were identified to have died as a result of complications from known legal induced abortions. No reported deaths were associated with known illegal induced abortions. Among the 47 areas that reported data every year during 2003-2012, the notable decreases that occurred during 2008-2011 in the total number, rate, and ratio of reported abortions continued from 2011 to 2012 and resulted in historic lows for all three measures of abortion. The data in this report can help to identify groups of women at greatest risk for abortion and can be used to guide and evaluate prevention efforts. Because unintended pregnancy is the major contributor to abortion, and unintended pregnancies are rare among women who use the most effective methods of contraception, increasing access to and use of these methods can help further reduce the number of unintended pregnancies, and therefore abortions, performed in the United States.

Since 1969, CDC has conducted abortion surveillance to document the number and characteristics of women obtaining legal induced abortions in the United States. 2014. Each year, CDC requests abortion data from the central health agencies of 52 reporting areas (the 50 states, the District of Columbia, and New York City). The reporting areas provide this information voluntarily. For 2014, data were received from 49 reporting areas. For trend analysis, abortion data were evaluated from 48 areas that reported data every year during 2005-2014. Census and natality data, respectively, were used to calculate abortion rates (number of abortions per 1,000 women aged 15-44 years) and ratios (number of abortions per 1,000 live births). A total of 652,639 abortions were reported to CDC for 2014. Of these abortions, 98.4% were from the 48 reporting areas that provided data every year during 2005-2014. Among these 48 reporting areas, the abortion rate for 2014 was 12.1 abortions per 1,000 women aged 15-44 years, and the abortion ratio was 186 abortions per 1,000 live births. From 2013 to 2014, the total number and rate of reported abortions decreased 2%, and the ratio decreased 7%. From 2005 to 2014, the total number, rate, and ratio of reported abortions decreased 21%, 22%, and 21%, respectively. In 2014, all three measures reached their lowest level for the entire period of analysis (2005-2014). In 2014 and throughout the period of analysis, women in their 20s accounted for the majority of abortions and had the highest abortion rates; women in their 30s and older accounted for a much smaller percentage of abortions and had lower abortion rates. In 2014, women aged 20-24 and 25-29 years accounted for 32.2% and 26.7% of all reported abortions, respectively, and had abortion rates of 21.3 and 18.4 abortions per 1,000 women aged 20-24 and 25-29 years, respectively. In contrast, women aged 30-34, 35-39, and ≥40 years accounted for 17.1%, 9.7%, and 3.6% of all reported abortions, respectively, and had abortion rates of 11.9, 7.2, and 2.6 abortions per 1,000 women aged 30-34 years, 35-39 years, and ≥40 years, respectively. From 2005 to 2014, the abortion rate decreased among women aged 20-24, 25-29, 30-34, and 35-39 years by 27%, 16%, 12%, and 5%, respectively, but increased 4% among women aged ≥40 years. In 2014, adolescents aged <15 and 15-19 years accounted for 0.3% and 10.4% of all reported abortions, respectively, and had abortion rates of 0.5 and 7.5 abortions per 1,000 adolescents aged <15 and 15-19 years, respectively. From 2005 to 2014, the percentage of abortions accounted for by adolescents aged 15-19 years decreased 38%, and their abortion rate decreased 49%. These decreases were greater than the decreases for women in any older age group. In contrast to the percentage distribution of abortions and abortion rates by age, abortion ratios in 2014 and throughout the entire period of analysis were highest among adolescents and lowest among women aged 30-39 years. Abortion ratios decreased from 2005 to 2014 for women in all age groups. In 2014, the majority (67.0%) of abortions were performed at ≤8 weeks' gestation, and nearly all (91.5%) were performed at ≤13 weeks' gestation. Few abortions were performed between 14 and 20 weeks' gestation (7.2%) or at ≥21 weeks' gestation (1.3%). During 2005-2014, the percentage of all abortions performed at ≤13 weeks' gestation remained consistently high (≥91.4%). Among abortions performed at ≤13 weeks' gestation, there was a shift toward earlier gestational ages, as the percentage performed at ≤6 weeks' gestation increased 21%, and the percentage of all other gestational ages at ≤13 weeks' gestation decreased 7%-20%. In 2014, among reporting areas that included medical (nonsurgical) abortion on their reporting form, 22.6% of all abortions were performed by early medical abortion (a nonsurgical abortion at ≤8 weeks' gestation), 67.4% were performed by surgical abortion at ≤13 weeks' gestation, and 8.6% were performed by surgical abortion at >13 weeks' gestation; all other methods were uncommon (<2%). Among abortions performed at ≤8 weeks' gestation that were eligible for early medical abortion on the basis of gestational age, 32.2% were completed by this method. In 2014, women with one or more previous live births accounted for 59.5% of abortions, and women with no previous live births accounted for 40.4%. Women with one or more previous induced abortions accounted for 44.9% of abortions, and women with no previous abortion accounted for 55.1%. Women with three or more previous births accounted for 13.8% of abortions, and women with three or more previous abortions accounted for 8.6% of abortions. Deaths of women associated with complications from abortion for 2014 are being assessed as part of CDC's Pregnancy Mortality Surveillance System. In 2013, the most recent year for which data were available, four women were identified to have died as a result of complications from legal induced abortion. Among the 48 areas that reported data every year during 2005-2014, the decreases in the total number, rate, and ratio of reported abortions that occurred during 2010-2013 continued from 2013 to 2014, resulting in historic lows for all three measures of abortion. The data in this report can help program planners and policymakers identify groups of women with the highest rates of abortion. Unintended pregnancy is the major contributor to induced abortion. Increasing access to and use of effective contraception can reduce unintended pregnancies and further reduce the number of abortions performed in the United States.

Complications of unsafe abortion are a significant cause of maternal morbidity and mortality in Myanmar, and are recognised by the Ministry of Health as a priority. The Department of Health developed a strategy to address the problem of abortion complications by integrating post-abortion care and contraceptive services into the existing township health system. The quality of post-abortion care was assessed by the Department of Health in 2000, using a baseline survey of health providers and post-abortion women in Bago Division. The integration of post-abortion care was led by the Township Medical Officers, who provided monthly in-service training and supervision of health care workers in each township. Hospital-based doctors and nurses, clinic midwives, village midwives and other volunteer health providers, including traditional birth attendants, were all trained. The role of the local clinic midwife was extended to make follow-up home visits to the women with post-abortion complications and provide them with contraception when requested. Preliminary results show positive outcomes. However, donor-funded projects may have a destabilizing effect on township services by diverting attention and resources; donors need to work with government to support its priorities for health care. The future nationwide integration of post-abortion care services into township services should be planned in consultation with Township Medical Officers and midwives, the key providers of these services.
First Stage Solid Propellant Multiply Debris Thermal Analysis

NASA Technical Reports Server (NTRS)

Toleman, Benjamin M.

2011-01-01

Destruction of a solid rocket stage of a launch vehicle can create a thermal radiation hazard for an aborting crew module. This hazard was assessed for the Constellation Program (Cx) crew and launch vehicle concept. For this concept, if an abort was initiated in first stage flight, the Crew Module (CM) will separate and be pulled away from the malfunctioning launch vehicle via a Launch Abort System (LAS). Having aborted the mission, the launch vehicle will likely be destroyed via a Flight Termination System (FTS) in order to prevent it from errantly traversing back over land and posing a risk to the public. The resulting launch vehicle debris field, composed primarily of first stage solid propellant, poses a threat to the CM. The harsh radiative thermal environment, caused by surrounding burning propellant debris, may lead to CM parachute failure. A methodology, detailed herein, has been developed to address this concern and to quantify the risk of first stage propellant debris leading to the thermal demise of the CM parachutes. Utilizing basic thermal radiation principles, a software program was developed to calculate parachute temperature as a function of time for a given abort trajectory and debris piece trajectory set. Two test cases, considered worst case aborts with regard to launch vehicle debris environments, were analyzed using the simulation: an abort declared at Mach 1 and an abort declared at maximum dynamic pressure (Max Q). For both cases, the resulting temperature profiles indicated that thermal limits for the parachutes were not exceeded. However, short duration close encounters by single debris pieces did have a significant effect on parachute temperature. Therefore while these two test cases did not indicate exceedance of thermal limits, in order to quantify the risk of parachute failure due to radiative effects from the abort environment, a more thorough probability-based analysis using the methodology demonstrated herein must be performed.
The Range Safety Debris Catalog Analysis in Preparation for the Pad Abort One Flight Test

The Pad Abort One flight test of the Orion Abort Flight Test Program is currently under development with the goal of demonstrating the capability of the Launch Abort System. In the event of a launch failure, this system will propel the Crew Exploration Vehicle to safety. An essential component of this flight test is range safety, which ensures the security of range assets and personnel. A debris catalog analysis was done as part of a range safety data package delivered to the White Sands Missile Range in New Mexico where the test will be conducted. The analysis discusses the consequences of an overpressurization of the Abort Motor. The resulting structural failure was assumed to create a debris field of vehicle fragments that could potentially pose a hazard to the range. A statistical model was used to assemble the debris catalog of potential propellant fragments. Then, a thermodynamic, energy balance model was applied to the system in order to determine the imparted velocity to these propellant fragments. This analysis was conducted at four points along the flight trajectory to better understand the failure consequences over the entire flight. The methods used to perform this analysis are outlined in detail and the corresponding results are presented and discussed.
Improvement in Capsule Abort Performance Using Supersonic Aerodynamic Interaction by Fences

Koyama, Hiroto; Wang, Yunpeng; Ozawa, Hiroshi; Doi, Katsunori; Nakamura, Yoshiaki

The space transportation system will need advanced abort systems to secure crew against serious accidents. Here this study deals with the capsule-type space transportation systems with a Launch Abort System (LAS). This system is composed of a conic capsule as a Launch Abort Vehicle (LAV) and a cylindrical rocket as a Service Module (SM), and the capsule is moved away from the rocket by supersonic aerodynamic interactions in an emergency. We propose a method to improve the performance of the LAV by installing fences at the edges of surfaces on the rocket and capsule sides. Their effects were investigated by experimental measurements and numerical simulations. Experimental results show that the fences on the rocket and capsule surfaces increase the aerodynamic thrust force on the capsule by 70% in a certain clearance between the capsule and rocket. Computational results show the detailed flow fields where the centripetal flow near the surface on the rocket side is induced by the fence on the rocket side and the centrifugal flow near the surface on the capsule side is blocked by the fence on the capsule side. These results can confirm favorable effects of the fences on the performance of the LAS.

Since 1969, CDC has conducted abortion surveillance to document the number and characteristics of women obtaining legal induced abortions in the United States. 1999-2008. Each year, CDC requests abortion data from the central health agencies of 52 reporting areas (the 50 states, the District of Columbia, and New York City). This information is provided voluntarily. For 2008, data were received from 49 reporting areas. For the purpose of trend analysis, data were evaluated from the 45 areas that reported data every year during 1999-2008. Abortion rates (number of abortions per 1,000 women) and ratios (number of abortions per 1,000 live births) were calculated using census and natality data, respectively. A total of 825,564 abortions were reported to CDC for 2008. Of these, 808,528 abortions (97.9% of the total) were from the 45 reporting areas that provided data every year during 1999-2008. Among these same 45 reporting areas, the abortion rate for 2008 was 16.0 abortions per 1,000 women aged 15-44 years, and the abortion ratio was 234 abortions per 1,000 live births. Compared with 2007, the total number and rate of reported abortions for these 45 reporting areas essentially were unchanged, although the abortion ratio was 1% higher. Reported abortion numbers, rates, and ratios remained 3%, 4%, and 10% lower, respectively, in 2008 than they had been in 1999. Women aged 20-29 years accounted for 57.1% of all abortions reported in 2008 and for the majority of abortions during the entire period of analysis (1999-2008). In 2008, women aged 20-29 years also had the highest abortion rates (29.6 abortions per 1,000 women aged 20-24 years and 21.6 abortions per 1,000 women aged 25-29 years). Adolescents aged 15-19 years accounted for 16.2% of all abortions in 2008 and had an abortion rate of 14.3 abortions per 1,000 adolescents aged 15-19 years; women aged ≥35 years accounted for a smaller percentage (11.9%) of abortions and had lower abortion rates (7.8 abortions per 1,000 women aged 35-39 years and 2.7 abortions per 1,000 women aged ≥40 years). Throughout the period of analysis, abortion rates decreased among adolescents aged ≤19 years, whereas they increased among women aged ≥35 years. Among women aged 20-24 years abortion rates decreased during 1999-2003 and then leveled off during 2004-2008. In contrast to the percentage distribution of abortions and abortion rates by age, abortion ratios in 2008 and throughout the entire period of analysis were highest among adolescents aged ≤19 years and lowest among women aged 30-39 years. Abortion ratios decreased during 1999-2008 for women in all age groups except for those aged <15 years; however, the steady decrease was interrupted from 2007 to 2008 when abortion ratios increased among women in all age groups except for those aged ≥40 years. In 2008, most (62.8%) abortions were performed at ≤8 weeks' gestation, and 91.4% were performed at ≤13 weeks' gestation. Few abortions (7.3%) were performed at 14-20 weeks' gestation, and even fewer (1.3%) were performed at ≥21 weeks' gestation. During 1999-2008, the percentage of abortions performed at ≤13 weeks' gestation remained stable, whereas abortions performed at ≥16 weeks' gestation decreased 13%-17%. Moreover, among the abortions performed at ≤13 weeks' gestation, the distribution shifted toward earlier gestational ages, with the percentage of abortions performed at ≤6 weeks' gestation increasing 53%. In 2008, 75.9% of abortions were performed by curettage at ≤13 weeks' gestation, and 14.6% were performed by early medical abortion (a nonsurgical abortion at ≤8 weeks' gestation); 8.5% of abortions were performed by curettage at >13 weeks' gestation. Among the 62.8% of abortions that were performed at ≤8 weeks' gestation and thus were eligible for early medical abortion, 22.5% were completed by this method. The use of medical abortion increased 17% from 2007 to 2008. Deaths of women associated with complications from abortions for 2008 are being investigated under CDC's Pregnancy Mortality Surveillance System. In 2007, the most recent year for which data were available, six women were reported to have died as a result of complications from known legal induced abortions. No reported deaths were associated with known illegal induced abortions. Among the 45 areas that reported data every year during 1999-2008, the total number and rate of reported abortions essentially did not change from 2007 to 2008. This finding is consistent with the recent leveling off from steady decreases that had been observed in the past. In contrast, the abortion ratio increased from 2007 to 2008 after having decreased steadily. In 2007, as in previous years, reported deaths related to abortion were rare. This report provides the data for examining trends in the number and characteristics of women obtaining abortions. This information is needed to better understand the reasons why efforts to reduced unintended pregnancy have stalled and can be used by policymakers and program planners to guide and evaluate efforts to prevent unintended pregnancy.

A total of 730,322 abortions were reported to CDC for 2011. Of these abortions, 98.3% were from the 46 reporting areas that provided data every year during 2002-2011. Among these same 46 reporting areas, the abortion rate for 2011 was 13.9 abortions per 1,000 women aged 15-44 years, and the abortion ratio was 219 abortions per 1,000 live births. From 2010 to 2011, the total number and rate of reported abortions decreased 5% and the abortion ratio decreased 4%, and from 2002 to 2011, the total number, rate, and ratio of reported abortions decreased 13%, 14%, and 12%, respectively. In 2011, all three measures reached their lowest level for the entire period of analysis (2002-2011).

In 2011, women aged 20-24 and 25-29 years accounted for 32.9% and 24.9% of all abortions, respectively, and had abortion rates of 24.9 and 19.4 abortions per 1,000 women aged 20-24 and 25-29 years, respectively. In contrast, women aged 30-34, 35-39, and ≥40 years accounted for 15.8%, 8.9%, and 3.6% of all abortions, respectively, and had abortion rates of 12.7, 7.5, and 2.8 abortions per 1,000 women aged 30-34 years, 35-39 years, and ≥40 years, respectively. Throughout the period of analysis, abortion rates decreased among women aged 20-24 and 25-29 years by 21% and 16%, respectively, whereas they increased among women aged ≥40 years by 8%. In 2011, adolescents aged <15 and 15-19 years accounted for 0.4% and 13.5% of all abortions, respectively, and had abortion rates of 0.9 and 10.5 abortions per 1,000 adolescents aged <15 and 15-19 years, respectively. From 2002 to 2011, the percentage of abortions accounted for by adolescents aged 15-19 years decreased 21% and their abortion rate decreased 34%.

Among abortions performed at ≤8 weeks' gestation that were eligible for early medical abortion on the basis of gestational age, 28.5% were completed by this method. The percentage of abortions reported as early medical abortions increased 3% from 2010 to 2011. Deaths of women associated with complications from abortions for 2011 are being investigated as part of CDC's Pregnancy Mortality Surveillance System. In 2010, the most recent year for which data were available, 10 women were identified to have died as a result of complications from known legal induced abortions.

Do State-Based Policies Have an Impact on Teen Birth Rates and Teen Abortion Rates in the United States?

The United States has one of the highest teen birth rates among developed countries. Interstate birth rates and abortion rates vary widely, as do policies on abortion and sex education. The objective of our study is to assess whether US state-level policies regarding abortion and sexual education are associated with different teen birth and teen abortion rates. We carried out a state-level (N = 51 [50 states plus the District of Columbia]) retrospective observational cross-sectional study, using data imported from the National Vital Statistics System. State policies were obtained from the Guttmacher Institute. We used descriptive statistics and regression analysis to study the association of different state policies with teen birth and teen abortion rates. The state-level mean birth rates, when stratifying between policies protective and nonprotective of teen births, were not statistically different-for sex education policies, 39.8 of 1000 vs 45.1 of 1000 (P = .2187); for mandatory parents' consent to abortion 45 of 1000, vs 38 of 1000 when the minor could consent (P = .0721); and for deterrents to abortion, 45.4 of 1000 vs 37.4 of 1000 (P = .0448). Political affiliation (35.1 of 1000 vs 49.6 of 1000, P < .0001) and ethnic distribution of the population were the only variables associated with a difference between mean teen births. Lower teen abortion rates were, however, associated with restrictive abortion policies, specifically lower in states with financial barriers, deterrents to abortion, and requirement for parental consent. While teen birth rates do not appear to be influenced by state-level sex education policies, state-level policies that restrict abortion appear to be associated with lower state teen abortion rates.

Since 1969, CDC has conducted abortion surveillance to document the number and characteristics of women obtaining legal induced abortions in the United States. 2009. Each year, CDC requests abortion data from the central health agencies of 52 reporting areas (the 50 states, the District of Columbia, and New York City). The reporting areas provide this information voluntarily. For 2009, data were received from 48 reporting areas. For the purpose of trend analysis, abortion data were evaluated from the 45 areas that reported data every year during 2000-2009. Census and natality data, respectively, were used to calculated abortion rates (number of abortions per 1,000 women) and ratios (number of abortions per 1,000 live births). A total of 784,507 abortions were reported to CDC for 2009. Of these abortions, 772,630 (98.5%) were from the 45 reporting areas that provided data every year during 2000-2009. Among these same 45 reporting areas, the abortion rate for 2009 was 15.1 abortions per 1,000 women aged 15-44 years, and the abortion ratio was 227 abortions per 1,000 live births. Compared with 2008, the total number and rate of reported abortions for 2009 decreased 5%, representing the largest single year decrease for the entire period of analysis. The abortion ratio decreased 2%. From 2000 to 2009, the total number, rate, and ratio of reported abortions decreased 6%, 7%, and 8%, respectively, to the lowest levels for 2000-2009. In 2009 and throughout the period of analysis, women in their 20s accounted for the majority of abortions and had the highest abortion rates, whereas women aged ≥30 years accounted for a much smaller percentage of abortions and had lower abortion rates. In 2009, women aged 20-24 and 25-29 years accounted for 32.7% and 24.4% of all abortions, respectively, and had an abortion rate of 27.4 abortions per 1,000 women aged 20-24 years and 20.4 abortions per 1,000 women aged 25-29 years. In contrast, women aged 30-34, 35-39, and ≥40 years accounted for 14.7%, 8.8%, and 3.3% of all abortions, respectively, and had an abortion rate of 13.3 abortions per 1,000 women aged 30-34 years, 7.6 abortions per 1,000 women aged 35-39 years, and 2.7 abortions per 1,000 women aged ≥40 years. Throughout the period of analysis, abortion rates decreased among women aged 20-24 and 25-29 years, whereas they increased among women aged ≥40 years. In 2009, adolescents aged 15-19 years accounted for 15.5% of all abortions and had an abortion rate of 13.0 abortions per 1,000 adolescents aged 15-19 years. Throughout the period of analysis, the percentage of all abortions accounted for by adolescents and the adolescent abortion rate decreased. In contrast to the percentage distribution of abortions and abortion rates by age, abortion ratios in 2009 and throughout the entire period of analysis were highest among adolescents and lowest among women aged 30-39 years. Abortion ratios decreased from 2000 to 2009 for women in all age groups except for those aged <15 years, for whom they increased. In 2009, most (64.0%) abortions were performed at ≤8 weeks' gestation, and 91.7% were performed at ≤13 weeks' gestation. Few abortions (7.0%) were performed at 14-20 weeks' gestation, and even fewer (1.3%) were performed at ≥21 weeks' gestation. From 2000 to 2009, the percentage of all abortions performed at ≤8 weeks' gestation increased 12%, whereas the percentage performed at >13 weeks' decreased 12%. Moreover, among abortions performed at ≤13 weeks' gestation, the distribution shifted toward earlier gestational ages, with the percentage of these abortions performed at ≤6 weeks' gestation increasing 47%. In 2009, 74.2% of abortions were performed by curettage at ≤13 weeks' gestation, 16.5% were performed by early medical abortion (a nonsurgical abortion at ≤8 weeks' gestation), and 8.1% were performed by curettage at >13 weeks' gestation. Among abortions that were performed at ≤8 weeks' gestation and thus were eligible for early medical abortion, 25.2% were completed by this method. The use of early medical abortion increased 10% from 2008 to 2009. Deaths of women associated with complications from abortions for 2009 are being investigated under CDC's Pregnancy Mortality Surveillance System. In 2008, the most recent year for which data were available, 12 women were reported to have died as a result of complications from known legal induced abortions. No reported deaths were associated with known illegal induced abortions. Among the 45 areas that reported data every year during 2000-2009, the gradual decrease that had occurred during previous decades in the total number and rate of reported abortions continued through 2005, whereas year-to-year variation from 2006 to 2008 resulted in no net change during this later period. However, the change from 2008 to 2009 for both the total number of abortions and the abortion rate was the largest single year decrease during 2000-2009, and all three measures of abortion (total numbers, rates, and ratios) decreased to the lowest level observed during this period. Unintended pregnancy is the major contributor to abortion. Because unintended pregnancies are rare among women who use the most effective methods of reversible contraception, increasing access to and use of these methods can help further reduce the number of abortions performed in the United States. The data in this report can help program planners and policy makers identify groups of women at greatest risk for unintended pregnancy and help guide and evaluate prevention efforts.
Conscientious objection and abortion: rights and duties of public sector physicians.

PubMed

Diniz, Debora

2011-10-01

The paper analyzes conscientious objection by physicians, through the concrete situation of legal abortion in Brazil. It reviews the two main ethical frameworks about conscientious objection in public health, the incompatibility thesis and the integrity thesis, to analyze the reality of legal abortion services in the referral services of the Brazilian public health care system. From these two perspectives, a third perspective is proposed - the justification thesis, to manage the right to conscientious objection among physicians in referral services. This analysis may contribute to the organization of services for legal abortion and to the education of future physicians working in emergency obstetric care.

To minimize the beam losses at the moment of an LHC beam dump the 3 μs long abort gap should contain as few particles as possible. Its population can be minimised by abort gap cleaning using the LHC transverse damper system. The LHC Run 1 experience is briefly recalled; changes foreseen for the LHC Run 2 are presented. They include improvements in the observation of the abort gap population and the mechanism to decide if cleaning is required, changes to the hardware of the transverse dampers to reduce the detrimental effect on the luminosity lifetime and proposed changes to themore » applied cleaning algorithms.« less

To investigate factors associated with self-reported pregnancy termination in Ghana and thereby appreciate the correlates of abortion-seeking in order to understand safe abortion care provision. In a retrospective study, data from the Ghana 2008 Demographic and Health Survey were used to investigate factors associated with self-reported pregnancy termination. Variables on an individual and household level were examined by both bivariate analyses and multivariate logistic regression. A five-point autonomy scale was created to explore the role of female autonomy in reported abortion-seeking behavior. Among 4916 women included in the survey, 791 (16.1%) reported having an abortion. Factors associated with abortion-seeking included being older, having attended school, and living in an urban versus a rural area. When entered into a logistic regression model with demographic control variables, every step up the autonomy scale (i.e. increasing autonomy) was associated with a 14.0% increased likelihood of reporting the termination of a pregnancy (P < 0.05). Although health system barriers might play a role in preventing women from seeking safe abortion services, autonomy on an individual level is also important and needs to be addressed if women are to be empowered to seek safe abortion services.

It has been speculated that the beam may cause instability of the RHIC Beam Abort Kickers. In this study, we explore the available data of past beam operations, the device history of key modulator components, and the radiation patterns to examine the correlations. The RHIC beam abort kicker system was designed and built in the 90's. Over last decade, we have made many improvements to bring the RHIC beam abort kicker system to a stable operational state. However, the challenge continues. We present the analysis of the pre-fire, an unrequested discharge of kicker, issues which relates to the RHIC machinemore » safety and operational stability.« less
A framework for analyzing sex-selective abortion: the example of changing sex ratios in Southern Caucasus

PubMed Central

Hohmann, Sophie A; Lefèvre, Cécile A; Garenne, Michel L

2014-01-01

The paper proposes a socioeconomic framework of supply, demand, and regulation to explain the development of sex-selective abortion in several parts of the world. The framework is then applied to three countries of southern Caucasus (Armenia, Azerbaijan, and Georgia) where sex-selective abortion has developed since the collapse of the Soviet Union. The authors argue that sex-selective abortion cannot be explained simply by patriarchal social systems, sex discrimination, or son preference. The emphasis is put on the long-term acceptability of abortion in the region, on acceptability of sex-screening by both the medical establishment and by the population, on newly imported techniques of sex-screening, and on the changing demand for children associated with the major economic and social changes that followed the dismantlement of the Soviet Union.

RISKS, REASONS AND RIGHTS: THE EUROPEAN CONVENTION ON HUMAN RIGHTS AND ENGLISH ABORTION LAW

PubMed Central

Scott, Rosamund

2016-01-01

Although there is no right to abort in English law but rather abortion is a crime, the lawful grounds for which are instantiated in the Abortion Act 1967 (as amended by the Human Fertilisation and Embryology Act 1990), the regulation of abortion is sometimes perceived as being fairly ‘liberal’. Accordingly, the idea that aspects of English law could be criticised under the European Convention on Human Rights, with which the UK must comply following the Human Rights Act 1998, may seem unlikely. Indeed, English law is compatible with the consensus amongst contracting states that abortion should be available on maternal health grounds. However, analysis of the UK's negative obligations under Article 8 shows that section 1(1)(a) of the Act is problematic as it operates in the first trimester. Further, given the European Court of Human Rights' emphasis on the reduced margin of appreciation once a state has legalised abortion to some degree and its jurisprudence relating to a state's positive obligations, the analysis shows that, while English law may not be problematic in relation to the lack of guidelines relating to the lawful grounds for abortion, it may well be in relation to the lack of a formal system for the review of any two doctors' decision not to grant a termination. Notwithstanding the morally serious nature of the decision to abort, the analysis overall raises questions about the need for at least some degree of abortion law reform, particularly in relation to the first trimester, towards a more autonomy-focused, though time-limited, rights-based approach.

OBJECTIVE To examine characteristics and causes of legal induced abortion–related deaths in the United States between 1998 and 2010. METHODS Abortion-related deaths were identified through the national Pregnancy Mortality Surveillance System with enhanced case-finding. We calculated the abortion mortality rate by race, maternal age, and gestational age and the distribution of causes of death by gestational age and procedure. RESULTS During the period from 1998–2010, of approximately 16.1 million abortion procedures, 108 women died, for a mortality rate of 0.7 deaths per 100,000 procedures overall, 0.4 deaths for non-Hispanic white women, 0.5 deaths for Hispanic women, and 1.1 deaths for black women. The mortality rate increased with gestational age, from 0.3 to 6.7 deaths for procedures performed at 8 weeks or less and at 18 weeks or greater, respectively. A majority of abortion-related deaths at 13 weeks of gestation or less were associated with anesthesia complications and infection, whereas a majority of abortion-related deaths at more than 13 weeks of gestation were associated with infection and hemorrhage. In 20 of the 108 cases, the abortion was performed as a result of a severe medical condition where continuation of the pregnancy threatened the woman’s life. CONCLUSION Deaths associated with legal induced abortion continue to be rare events—less than 1 per 100,000 procedures. Primary prevention of unintended pregnancy, including those in women with serious pre-existing medical conditions, and increased access to abortion services at early gestational ages may help to further decrease abortion-related mortality in the United States.

Background The purpose of this study was to investigate attributes of public service providers associated with the provision of medical abortion in Vietnam. Methods We conducted a cross-sectional study via interviewer-administered questionnaire among abortion providers from public health facilities in Hanoi, Khanh Hoa, and Ho Chi Minh City in Vietnam between August 2011 and January 2012. We recruited abortion providers at all levels of Vietnam’s public health service delivery system. Participants were questioned about their medical abortion provision practices and perspectives regarding abortion methods. Results A total of 905 providers from 62 health facilities were included, comprising 525 (58.0%) from Hanoi, 122 (13.5%) from Khanh Hoa, and 258 (28.5%) from Ho Chi Minh City. The majority of providers were female (96.7%), aged ≥25 years (94%), married (84.4%), and had at least one child (89%); 68.9% of providers offered only manual vacuum aspiration and 31.1% performed both medical abortion and manual vacuum aspiration. Those performing both methods included physicians (74.5%), midwives (21.7%), and nurses (3.9%). Unadjusted analyses showed that female providers (odds ratio 0.1; 95% confidence interval 0.01–0.30) and providers in rural settings (odds ratio 0.3; 95% confidence interval 0.08–0.79) were less likely to provide medical abortion than their counterparts. Obstetricians and gynecologists were more likely to provide medical abortion than providers with nursing/midwifery training (odds ratio 22.2; 95% confidence interval 3.81–129.41). The most frequently cited advantages of medical abortion for providers were that no surgical skills are required (61.7%) and client satisfaction is better (61.0%). Conclusion Provision of medical abortion in Vietnam is lower than provision of manual vacuum aspiration. While the majority of abortion providers are female midwives in Vietnam, medical abortion provision is concentrated in urban settings among physicians. Individuals providing medical abortion found that the method yields high client satisfaction. PMID:25152635
Overview of C/C-SiC Composite Development for the Orion Launch Abort System

2012-01-01

Past and present efforts by the authors to further understanding of the ceramic matrix composite (CMC) material used in the valve components of the Orion Launch Abort System (LAS) Attitude Control Motor (ACM) will be presented. The LAS is designed to quickly lift the Orion Crew Exploration Vehicle (CEV) away from its launch vehicle in emergency abort scenarios. The ACM is a solid rocket motor which utilizes eight throttleable nozzles to maintain proper orientation of the CEV during abort operations. Launch abort systems have not been available for use by NASA on manned launches since the last Apollo ]Saturn launch in 1975. The CMC material, carbon-carbon/silicon-carbide (C/C-SiC), is manufactured by Fiber Materials, Inc. and consists of a rigid 4-directional carbon-fiber tow weave reinforced with a mixed carbon plus SiC matrix. Several valve and full system (8-valve) static motor tests have been conducted by the motor vendor. The culmination of these tests was the successful flight test of the Orion LAS Pad Abort One (PA ]1) vehicle on May 6, 2010. Due to the fast pace of the LAS development program, NASA Marshall Space Flight Center assisted the LAS community by performing a series of material and component evaluations using fired hardware from valve and full ]system development motor tests, and from the PA-1 flight ACM motor. Information will be presented on the structure of the C/C-SiC material, as well as the efficacy of various non ]destructive evaluation (NDE) techniques, including but not limited to: radiography, computed tomography, nanofocus computed tomography, and X-ray transmission microscopy. Examinations of the microstructure of the material via scanning electron microscopy and energy dispersive spectroscopy will also be discussed. The findings resulting from the subject effort are assisting the LAS Project in risk assessments and in possible modifications to the final ACM operational design.
Factors affecting delays in first trimester pregnancy termination services in New Zealand.

To identify the factors affecting the timeliness of services in first trimester abortion service in New Zealand. Primary data were collected from all patients attending nine abortion clinics between February and May 2009. The outcome measured was delay between the first visit with a referring doctor and the date of the abortion procedure. Patient records (n=2,950) were audited to determine the timeline between the first point of entry to the health system and the date of abortion. Women were also invited to fill out a questionnaire identifying personal factors affecting access to services (n=1,086, response rate = 36.8%). Women who went to private clinic had a significantly shorter delay compared to public clinics. Controlling for clinic type, women who went to clinics that offered medical abortions or clinics that offered single day services experienced less delay. Also, women who had more than one visit with their referring doctor experienced a greater delay than those who had a single visit. The earlier in pregnancy women sought services the longer the delay. Women's decision-making did not have a significant effect on delay. Several clinic level and systemic factors are significantly associated with delay in first trimester abortion services. In order to ensure the best physical and emotional outcomes, timeliness of services must improve. © 2011 The Authors. ANZJPH © 2011 Public Health Association of Australia.
Sneaky Submarine Landslides, and how to Quantify them: A Case Study from the Mississippi River Delta Front Contrasting Geophysical and Machine Learning Techniques

The highly publicized subsidence and decline of the Mississippi River Delta Front's (MRDF) subaerial section has recently precipitated studies of the subaqueous MRDF to assess whether it too is subsiding and regressing landward. These studies have largely focused on the area offshore the most active current distributary of the Mississippi River, Southwest Pass, during a decade (post-Hurricane Rita 2005-2014) of relatively quiescent Gulf of Mexico hurricane activity. Utilizing repeat swath bathymetric surveys, it was determined that submarine landslides not associated with major (category ≥ 3) passage are important drivers of downslope sediment transport on the MRDF. Volumetrically, sediment flux downslope without major hurricane influence is approximately half that during a given hurricane-influenced year (5.5 x 105 and 1.1 x 106 m3, respectively). This finding is notable and warrants comparison with other settings to assess the global impact on the source-to-sink budget of small but frequent landslides, but the resource-intensive repeat geophysical surveys required make it a prohibitive option at the margin and global scale. One option to quantify small-scale submarine slope failures while reducing required data acquisition is to utilize machine learning algorithms (MLAs) to intelligently estimate the occurrence and magnitude of submarine landslides based on correlated physical and geological parameters. Here, the MRDF volumetric changes described above are parsed into training and validation data, and physical and geological parameters associated with slope failure (such as porosity, steep slopes, high rates of sedimentation, and presence of gas in pore water) known from prior coring and seafloor mapping expeditions serve as potential predictive variables. The resulting submarine landslide spatial distribution and magnitude maps output by the MLAs are compared to those obtained through geophysical surveys, providing a proof of concept that machine learning can complement and expand the reach of previously acquired geophysical and geological data.

2002-01-01

The Five Segment Booster (FSB) concept has been evolving for a number of years as a means to enhance the overall safety and reliability of the Space Shuttle system by minimizing the need to fly the more challenging Return to Launch Site (RTLS) and Transoceanic Abort Landing (TAL) abort profiles. The initial evaluation of the FSB concept was conducted in 1996 to determine the feasibility of the FSB in achieving transatlantic abort leading TAL from the pad, thus eliminating the return to launch site (RTLS) abort mode. The initial study was conducted by ATK Thiokol and did show the potential for the FSB to eliminate the RTLS abort mode. Later Rockwell (now Boeing) conducted a similar study utilizing FSB performance characteristics and verified that the FSB could indeed achieve TAL from the pad, thereby eliminating the necessity for the RTLS abort. The purpose of this paper is to discuss the details of the enhancements achieved through the internally funded study conducted by Boeing and ATK Thiokol. To better understand the enhancements that were addressed as part of this follow-on study, some background on what was achieved in the Phase A study is appropriate.
After After Tiller: the impact of a documentary film on understandings of third-trimester abortion.

Sisson, Gretchen; Kimport, Katrina

2016-01-01

Onscreen pseudo-experiences have been shown to influence public perceptions of contested social issues. However, research has not considered whether such experiences have limits in their influence and/or vary in their impact. Using the case of third-trimester abortion, an issue subject to high amounts of misinformation, low public support and low occurrence in the general population, we investigate how the pseudo-experience of viewing After Tiller, a documentary film showing stories of third-trimester abortion, providers and patients, might serve as a counterpoint to misinformation and myth. We interviewed 49 viewers to assess how viewing the film interacted with viewers' previously held understandings of later abortion. Participants reported that viewing made them feel more knowledgeable about later-abortion patients and providers and increased their support for legal third-trimester abortion access, suggesting the efficacy of this pseudo-experience in changing belief. Nonetheless, respondents' belief systems were not entirely remade and the effects of the film varied, particularly in regards to gatekeeping around the procedure and the reasons why women seek later abortion. Findings show the potential of onscreen pseudo-experiences as a means for social change, but also reveal their limits and varying impacts.

A descriptive study was undertaken on 595 dairy cattle abortion submissions to the California Veterinary Diagnostic Laboratory System from July 1, 1987, to December 31, 1989, to determine the etiologic nature and distribution (seasonal and geographical) of dairy cattle abortion in California as reflected by laboratory submissions. Univariate analysis was performed to characterize abortion-related submissions by farm and laboratory variables, and logistic regression analysis was performed to determine factors that may influence success of abortion diagnosis in the laboratory. The proportions of dairies that submitted abortion-related specimens from northern, central, and southern milksheds during the 2.5-year period were 20.3%, 15.7%, and 13.1%, respectively, and 60% of submissions were from medium-sized (200-999 cows) dairies. Submissions consisted of fetus (58%), placenta (2%), fetus and placenta (12%), and fetus, placenta, and maternal blood (0.84%); fetal tissues and uterine fluid constituted the rest. An apparent pattern in abortion submissions was indicated by a peak in submissions during the winter and summer of 1988 and 1989. Infectious agents were associated with 37.1% of submissions; noninfectious causes, 5.5%, and undetermined etiology, 57.3%. Bacterial abortion accounted for 18% of etiologic diagnoses; protozoal, 14.6%; viral, 3.2%; and fungal, 1.3%. Submissions comprising fetus, placenta, maternal blood, or their combinations were associated with a higher likelihood of definitive diagnosis for abortion than tissues, as were fresher specimens and submissions associated with the second trimester of fetal gestation.

CONTINUOUS ABORT GAP CLEANING AT RHIC.

2004-07-05

Since the RHIC Au-Au run in the year 2001 the 200 MHz cavity system was used at storage and a 28 MHz system during injection and acceleration. The rebucketing procedure potentially causes a higher debunching rate of heavy ion beams in addition to amplifying debunching due to other mechanisms. At the end of a four hour store, debunched beam can easily account for more than 50% of the total beam intensity. This effect is even stronger with the achieved high intensities of the RHIC Au-Au run in 2004. A beam abort at the presence of a lot of debunched beammore » bears the risk of magnet quenching and experimental detector damage due to uncontrolled beam losses. Thus it is desirable to avoid any accumulation of debunched beam from the beginning of each store, in particular to anticipate cases of unscheduled beam aborts due to a system failure. A combination of a fast transverse kickers and the new 2-stage copper collimator system are used to clean the abort gap continuously throughout the store with a repetition rate of 1 Hz. This report gives. an overview of the new gap cleaning procedure and the achieved performance.« less

This article presents estimates based on the research conducted in 2010 of the cost to the Ugandan health system of providing post-abortion care (PAC), filling a gap in knowledge of the cost of unsafe abortion. Thirty-nine public and private health facilities were sampled representing three levels of health care, and data were collected on drugs, supplies, material, personnel time and out-of-pocket expenses. In addition, direct non-medical costs in the form of overhead and capital costs were also measured. Our results show that the average annual PAC cost per client, across five types of abortion complications, was $131. The total cost of PAC nationally, including direct non-medical costs, was estimated to be $13.9 million per year. Satisfying all demand for PAC would raise the national cost to $20.8 million per year. This shows that PAC consumes a substantial portion of the total expenditure in reproductive health in Uganda. Investing more resources in family planning programmes to prevent unwanted and mistimed pregnancies would help reduce health systems costs. PMID:23274438

2010-01-01

NASA s next manned launch platform for missions to the moon and Mars are the Orion and Ares systems. Many critical aspects of the launch system performance are being verified using computational fluid dynamics (CFD) predictions. The Orion Launch Abort Vehicle (LAV) consists of a tower mounted tractor rocket tasked with carrying the Crew Module (CM) safely away from the launch vehicle in the event of a catastrophic failure during the vehicle s ascent. Some of the predictions involving the launch abort system flow fields produced conflicting results, which required further investigation through ground test experiments. Ground tests were performed to acquire data from a hot supersonic jet in cross-flow for the purpose of validating CFD turbulence modeling relevant to the Orion Launch Abort Vehicle (LAV). Both 2-component axial plane Particle Image Velocimetry (PIV) and 3-component cross-stream Stereo Particle Image Velocimetry (SPIV) measurements were obtained on a model of an Abort Motor (AM). Actual flight conditions could not be simulated on the ground, so the highest temperature and pressure conditions that could be safely used in the test facility (nozzle pressure ratio 28.5 and a nozzle temperature ratio of 3) were used for the validation tests. These conditions are significantly different from those of the flight vehicle, but were sufficiently high enough to begin addressing turbulence modeling issues that predicated the need for the validation tests.

Since 1969, CDC has conducted abortion surveillance to document the number and characteristics of women obtaining legal induced abortions in the United States. 2010. Each year, CDC requests abortion data from the central health agencies of 52 reporting areas (the 50 states, the District of Columbia, and New York City). The reporting areas provide this information voluntarily. For 2010, data were received from 49 reporting areas. For the purpose of trend analysis, abortion data were evaluated from the 46 areas that reported data every year during 2001-2010. Census and natality data, respectively, were used to calculate abortion rates (number of abortions per 1,000 women) and ratios (number of abortions per 1,000 live births). A total of 765,651 abortions were reported to CDC for 2010. Of these abortions, 753,065 (98.4%) were from the 46 reporting areas that provided data every year during 2001-2010. Among these same 46 reporting areas, the abortion rate for 2010 was 14.6 abortions per 1,000 women aged 15-44 years, and the abortion ratio was 228 abortions per 1,000 live births. Compared with 2009, the total number and rate of reported abortions for 2010 decreased 3% and reached the lowest levels for the entire period of analysis (2001-2010); the abortion ratio was stable, changing only 0.4%. From 2001 to 2010, the total number, rate, and ratio of reported abortions decreased 9%, 10%, and 8%, respectively. Given the 3% decrease from 2009 to 2010 in the total number and rate of reported abortions, in combination with the 5% decrease that had occurred in the previous year from 2008 to 2009, the overall decrease for both measures was greater during 2006-2010 than during 2001-2005, despite the annual variations that resulted in no net decrease during 2006-2008. In 2010 and throughout the period of analysis, women in their 20s accounted for the majority of abortions and had the highest abortion rates, whereas women in their 30s and older accounted for a much smaller percentage of abortions and had lower abortion rates. In 2010, women aged 20-24 and 25-29 years accounted for 32.9% and 24.5% of all abortions, respectively, and had abortion rates of 26.7 and 20.2 abortions per 1,000 women aged 20-24 and 25-29 years, respectively. In contrast, women aged 30-34, 35-39, and ≥40 years accounted for 15.3%, 8.9%, and 3.4% of all abortions, respectively, and had abortion rates of 13.2, 7.6, and 2.8 abortions per 1,000 women aged 30-34 years, 35-39 years, ≥40 years, respectively. Throughout the period of analysis, abortion rates decreased among women aged 20-24 and 25-29 years, whereas they increased among women aged ≥40 years. In 2010, adolescents aged 15-19 years accounted for 14.6% of all abortions and had an abortion rate of 11.7 abortions per 1,000 adolescents aged 15-19 years. Throughout the period of analysis, the percentage of all abortions accounted for by adolescents and the adolescent abortion rate decreased. In contrast to the percentage distribution of abortions and abortion rates by age, abortion ratios in 2010 and throughout the entire period of analysis were highest among adolescents and lowest among women aged 30-39 years. Abortion ratios decreased from 2001 to 2010 for women in all age groups except for those aged <15 years, for whom they increased. In 2010, most (65.9%) abortions were performed at ≤8 weeks' gestation, and 91.9% were performed at ≤13 weeks' gestation. Few abortions (6.9%) were performed at 14-20 weeks' gestation, and even fewer (1.2%) were performed at ≥21 weeks' gestation. From 2001 to 2010, the percentage of all abortions performed at ≤8 weeks' gestation increased 10%, whereas the percentage performed at >13 weeks' decreased 10%. Moreover, among abortions performed at ≤13 weeks' gestation, the distribution shifted toward earlier gestational ages, with the percentage of these abortions performed at ≤6 weeks' gestation increasing 36%. In 2010, a total of 72.4% of abortions were performed by curettage at ≤13 weeks' gestation, 17.7% were performed by early medical abortion (a nonsurgical abortion at ≤8 weeks' gestation), and 8.3% were performed by curettage at >13 weeks' gestation. Among abortions that were performed at ≤8 weeks' gestation, and thus were eligible for early medical abortion on the basis of gestational age, 26.5% were completed by this method. From 2009 to 2010, the use of early medical abortion increased 13%. Deaths of women associated with complications from abortions for 2010 are being investigated under CDC's Pregnancy Mortality Surveillance System. In 2009, the most recent year for which data were available, eight women were identified to have died as a result of complications from known legal induced abortions. No reported deaths were associated with illegal induced abortions. Among the 46 areas that reported data every year during 2001-2010, the gradual decrease that had occurred during previous decades in the total number and rate of reported abortions continued through 2005, whereas year-to-year variation from 2006 to 2008 resulted in no net change during this later period. However, the large decreases that occurred both from 2008 to 2009 and from 2009 to 2010 resulted in a greater overall decrease during 2006-2010 as compared with 2001-2005 and the lowest number and rate of reported abortions for the entire period of analysis. Unintended pregnancy is the major contributor to abortion. Because unintended pregnancies are rare among women who use the most effective methods of reversible contraception, increasing access to and use of these methods can help further reduce the number of abortions performed in the United States. The data in this report can help program planners and policy makers identify groups of women at greatest risk for unintended pregnancy and help guide and evaluate prevention efforts.
Legacies of 1917 in Contemporary Russian Public Health: Addiction, HIV, and Abortion

I examine the legacies of Soviet public health policy and the socialist health care system and trace how the Soviet past figures in contemporary Russian policymaking and debates about drug use, HIV, and abortion. Drug policies and mainstream views of HIV reflect continuities with key aspects of Soviet-era policies, although political leaders do not acknowledge these continuities in justifying their policies. In abortion policy, by contrast, which is highly debated in the public realm, advocates represent themselves as differing from Soviet-era policies to justify their positions. Yet abortion activists’ views of the past differ tremendously, reminding us that the Soviet past is symbolically productive for arguments about Russia’s present and future. I describe key aspects of the Soviet approach to health and compare how current drug policy (and the related management of HIV/AIDS) and abortion policies are discursively shaped in relation to the Soviet historical and cultural legacy.

Unintended pregnancy among adolescents (10-19years) and young women (20-24years) is a global public health problem. Adolescents face challenges in accessing safe abortion care. To determine, via a systematic data review, whether abortion care for adolescent and young women differs clinically from that for older women. In a comprehensive data review, the Cochrane Central Register of Controlled Trials, MEDLINE, and POPLINE databases were searched from the earliest data entered until November 2012. Randomized controlled trials and observational studies comparing effectiveness, safety, acceptability, and long-term sequelae of abortion care between adolescent/young women and older women were identified. Two reviewers independently extracted data, and the Cochrane guidelines and Newcastle-Ottawa Scale were used for quality assessment. In total, there were 25 studies including 346 000 women undergoing first- and second-trimester medical abortion, vacuum aspiration, or dilation and evacuation. Effectiveness and overall complications were similar among age groups. However, younger women had an increased risk for cervical laceration and a decreased risk of uterine perforation and mortality. Satisfaction and long-term depression were similar between age groups. Except for less uptake of intrauterine devices among adolescents, age did not affect post-abortion contraception. Evidence from various healthcare systems indicates that abortion is safe and efficacious among adolescent and young women. Clinical services should promote access to safe abortion for adolescents. © 2013.

The purpose of this study was to analyze risk factors for abortion among female teenagers from 12 to 19 years of age in the city of Maceió, Brazil. This is a cross-sectional study, conducted in ten schools. The sample was calculated by considering the number of admissions for postabortion curettage, obtained from the Information System of Hospitalization. Data were obtained through a semi-structured questionnaire divided into three basic blocks of data: sociodemographic, sexual life, and pregnancy/abortion. To analyze the data, the logistic regression model was used. The Forward Method was chosen to set the final model that minimizes the number of variables and maximizes the accuracy of the model. The significant analysis between the dichotomous variables provided eight significant variables. Two of them are protective for abortion: the ages 12-14 years and talking with parents about sex. After the logistic regression, the receipt of support for abortion was the most significant variable of all. The adolescent with an active sexual life, a previous pregnancy, who is married, and has received support for an abortion has a 99.74% probability for an abortion. The results of this study, demonstrating the importance of the group in adolescence, and the statistical significance of having a partner to support and approve the pregnancy appears as a preventive factor for abortion. It shows the importance of support and companionship for adolescent women.

Objectives The abortion rate varies greatly within the French overseas territories including the Caribbean island of Guadeloupe and La Réunion in the Indian Ocean. We compare women’s contraceptive paths surrounding an abortion in both territories. Methods The data for this study are part of a nationally representative survey of women undergoing abortion in France in 2007. The analysis included 1211women from Guadeloupe and 1531 from La Réunion. Results Results show differences in women’s use of contraception before the abortion by study location. Women in Guadeloupe were more likely not to have used contraception in the month they conceived (40% vs. 32%, p < 001). Among those using no contraception or less effective contraception before the abortion, 74% in Guadeloupe and 86% in La Réunion received a prescription for a very effective method such as a hormonal method or intrauterine device after the procedure. In both settings, women with no health insurance or a government health plan were 70% less likely to have received a prescription for a very effective method. Conclusions While this study shows a significant increase in the prescription of very effective methods, it also indicates the ineffectiveness of the health care system in closing the gap in the pre-abortion contraceptive disparities observed between Guadeloupe and La Réunion.

Mental health problems are associated with women's reproductive decisions and predict poor mental health outcomes after abortion and childbirth. To study whether having a first-trimester induced abortion influenced the risk of psychiatric readmission and compare findings with readmission risk in women with mental disorders giving birth. Survival analyses were performed in a population-based cohort study merging data from the Danish Civil Registration System, the Danish Psychiatric Central Register, and the Danish National Hospital Register from January 1,1994, to December 31, 2007. Denmark. All women born in Denmark between 1962 and 1992 with a record of 1 or more psychiatric admissions at least 9 months before a first-time first-trimester induced abortion or childbirth. Main Outcome Measure Readmission at a psychiatric hospital with any type of mental disorder from 9 months before to 12 months after a first-time first-trimester induced abortion or childbirth. Relative risk (RR) for readmission risk 9 to 0 months before a first-trimester induced abortion was 0.95 (95% CI, 0.73-1.23) compared with the first year after the abortion. This contrasts with a reduced risk of readmission before childbirth (RR, 0.56; 95% CI, 0.42-0.75) compared with the first year post partum. Proximity to previous psychiatric admission in particular predicted rehospitalization risks in both the abortion and the childbirth group. Risk of readmission is similar before and after first-time first-trimester abortion, contrasting with a marked increased in risk of readmission post partum. We speculate that recent psychiatric episodes may influence women's decisions to have an induced abortion; however, this decision does not appear to influence the illness course in women with a history of treated mental disorders.
Healthcare students' knowledge and opinions about the Argentinean abortion law.

Abortion is legally restricted in Argentina. Although this law is almost 100 years old, most women who meet the criteria for legal abortion are not informed of or offered this possibility within the healthcare system. Healthcare students' knowledge and opinions on abortion may influence their future practice. They may deny a woman with an unwanted pregnancy a practice to which she is legally entitled, resulting in an unsafe abortion. This study assessed knowledge and personal opinions on the abortion law among first year healthcare students in order to design adequate educational strategies. In this descriptive, analytical, cross-sectional study, structured self-administered questionnaires were administered to 781 first year medical, nursing, midwifery, and other healthcare students from the Faculty of Medicine, University of Buenos Aires from 2011 to 2013. Data were recorded anonymously in SPSS 20. Student samples were adjusted for gender and fields of study using the University statistics. Of the students, 48.8% did not know the current regulations. Most of the students thought abortion was legally restricted and failed to recognize the circumstances in which it is allowed. Over 75% of the students were pro-abortion, especially those with sexual experience. Students lack sound knowledge on the abortion law that may affect their personal lives and influence their future professional practice. It is crucial that medical schools include sexual and reproductive health issues in their curricula in order to ensure better quality healthcare services in the future. In Argentina, approximately 400,000 abortions are performed every year, many under unsafe conditions, resulting in one third of the maternal deaths for the past decade. High quality sexual and reproductive healthcare services are a key strategy to improve adolescents' and women's health, thereby lowering maternal mortality. Copyright © 2015 Elsevier B.V.

RISKS, REASONS AND RIGHTS: THE EUROPEAN CONVENTION ON HUMAN RIGHTS AND ENGLISH ABORTION LAW.

PubMed

Scott, Rosamund

2016-01-01

Although there is no right to abort in English law but rather abortion is a crime, the lawful grounds for which are instantiated in the Abortion Act 1967 (as amended by the Human Fertilisation and Embryology Act 1990), the regulation of abortion is sometimes perceived as being fairly 'liberal'. Accordingly, the idea that aspects of English law could be criticised under the European Convention on Human Rights, with which the UK must comply following the Human Rights Act 1998, may seem unlikely. Indeed, English law is compatible with the consensus amongst contracting states that abortion should be available on maternal health grounds. However, analysis of the UK's negative obligations under Article 8 shows that section 1(1)(a) of the Act is problematic as it operates in the first trimester. Further, given the European Court of Human Rights' emphasis on the reduced margin of appreciation once a state has legalised abortion to some degree and its jurisprudence relating to a state's positive obligations, the analysis shows that, while English law may not be problematic in relation to the lack of guidelines relating to the lawful grounds for abortion, it may well be in relation to the lack of a formal system for the review of any two doctors' decision not to grant a termination. Notwithstanding the morally serious nature of the decision to abort, the analysis overall raises questions about the need for at least some degree of abortion law reform, particularly in relation to the first trimester, towards a more autonomy-focused, though time-limited, rights-based approach. © The Author 2015.

First Stage Solid Propellant Multi Debris Thermal Analysis

NASA Technical Reports Server (NTRS)

Toleman, Benjamin M.

2011-01-01

The crew launch vehicle considered for the Constellation (Cx) Program utilizes a first stage solid rocket motor. If an abort is initiated in first stage flight the Crew Module (CM) will separate and be pulled away from the launch vehicle via a Launch Abort System (LAS) in order to safely and quickly carry the crew away from the malfunction launch vehicle. Having aborted the mission, the launch vehicle will likely be destroyed via a Flight Termination System (FTS) in order to prevent it from errantly traversing back over land and posing a risk to the public. The resulting launch vehicle debris field, composed primarily of first stage solid propellant, poses a threat to the CM. The harsh radiative thermal environment induced by surrounding burning propellant debris may lead to CM parachute failure. A methodology, detailed herein, has been developed to address this concern and quantify the risk of first stage propellant debris leading to radiative thermal demise of the CM parachutes. Utilizing basic thermal radiation principles, a software program was developed to calculate parachute temperature as a function of time for a given abort trajectory and debris piece trajectory set. Two test cases, considered worst-case aborts with regard to launch vehicle debris environments, were analyzed using the simulation: an abort declared at Mach 1 and an abort declared at maximum dynamic pressure (Max Q). For both cases, the resulting temperature profiles indicated that thermal limits for the parachutes were not exceeded. However, short duration close encounters by single debris pieces did have a significant effect on parachute temperature, with magnitudes on the order of 10 s of degrees Fahrenheit. Therefore while these two test cases did not indicate exceedance of thermal limits, in order to quantify the risk of parachute failure due to radiative effects from the abort environment, a more thorough probability-based analysis using the methodology demonstrated herein must be performed.

Identification of the causes of abortion among the huge population of small ruminants in Algeria (≈31 millions heads), is an important task for the control of livestock productivity and viability scourges to the small ruminants industry. Optimal production and utilization is constrained by a number of factors: disease, poor feeding and low management skills. Therefore, in the present study the prevalence of abortion in Algerian small ruminant's flocks was estimated and its possible association was correlated with infectious (PPR, BT and Brucellosis seropositivity) and managerial (flock size, grazing system, type of farming, and contact with other flocks) risk factors. The present study showed an overall flock prevalence of small ruminant's abortion as 75.33% (113/150) [95% CI 71.72-78.94%]. The risk factor analysis using multivariable logistic regression recognized the north-western and the steppe region as well as PPR positivity as a risk factor for abortion in Algerian small ruminant's flocks. The odds of flock abortion was 11.47 [95% CI 2.39-54.88; P=0.002] and 10.31 [95% CI 1.28-82.88; P=0.028] times higher in north-western and steppe regions respectively compared to other region. Also the presence of PPRV infection in small ruminant flocks amplified the odds by 6 times [95% CI 2.221-17.427; P=0.001].Surprisingly, the univariate analysis for the other risk factors associated with abortions in Algerian small ruminant flocks indicated no statistically significant links with bluetongue (P=1.000) and brucellosis seropositivity (P=0.334). Flock size (P=0.574), type of farming (P=0.443), grazing system (P=0.117) and contact with other flocks (P=0.245) was also not statistically significant. Our results revealed that abortion in small ruminants is a challenge to farmers and PPR was chiefly linked to it. Therefore an effective vaccination and control programme is advocated for small ruminants in Algeria. Copyright © 2015 Elsevier B.V. All rights reserved.
Strengthening health systems capacity to monitor and evaluate programmes targeted at reducing abortion-related maternal mortality in Jessore district, Bangladesh.

Abortion related deaths as a proportion of maternal mortality appears to have fallen dramatically in Bangladesh from 5 % in 2001 to 1 % in 2010. Yet complications from menstrual regulation (MR) and unsafe abortion continue to cause deleterious health, economic and social consequences for women in the country. This quasi experimental design study with a baseline (January to December 2008) and an endline survey (August to October 2009) was conducted in 69 public, private, and NGO sector health facilities in Jessore district of Bangladesh with the objective of adapting and implementing a set of process indicators, specifically to supplement the indicators for monitoring emergency obstetric care interventions. At the baseline, we collected retrospective data from all 69 health facilities that provided MR, legal abortion or post-abortion care (PAC), by reviewing their last one year's records. Three months after introducing the safe menstrual regulation and abortion care (SMRAC) model, endline data was collected. Signal function (critical services that facilities must perform in order to prevent and treat abortion complications) analysis was used to characterize facilities as providing basic care, comprehensive care, or neither. Facility mapping, and records on services provided and complications treated were used to further characterize service availability and to describe service use and quality. No facilities fulfilled criteria for 'comprehensive' care at either the baseline or end line while only one met the 'basic' criteria during the endline of the project. Recommended uterine evacuation technology, manual vacuum aspiration (MVA) was used for 100.0 % of MR clients but only for 8.0 % or fewer PAC patients. MR clients were 37.5 times more likely than PAC patients to leave facilities with a contraceptive method (75.0 % vs. 2.0 %). Persistent use of older uterine evacuation technologies was observed when recommended techniques were widely available in the facilities. Notable gaps were identified in providing post-abortion contraceptive services for women treated for PAC. By systematic implementation of the SMRAC model, health systems can track and measure progress and gaps in their implementation and identify strategies for further reduction of abortion-related morbidity and mortality in Bangladesh.

The aim of this paper is to provide a panoramic view of laws and policies on abortion around the world, giving a range of country-based examples. It shows that the plethora of convoluted laws and restrictions surrounding abortion do not make any legal or public health sense. What makes abortion safe is simple and irrefutable-when it is available on the woman's request and is universally affordable and accessible. From this perspective, few existing laws are fit for purpose. However, the road to law reform is long and difficult. In order to achieve the right to safe abortion, advocates will need to study the political, health system, legal, juridical, and socio-cultural realities surrounding existing law and policy in their countries, and decide what kind of law they want (if any). The biggest challenge is to determine what is possible to achieve, build a critical mass of support, and work together with legal experts, parliamentarians, health professionals, and women themselves to change the law-so that everyone with an unwanted pregnancy who seeks an abortion can have it, as early as possible and as late as necessary.

Transversely modulated electron beams can be formed in photo injectors via microlens array (MLA) UV laser shap- ing technique. Microlenses can be arranged in polygonal lattices, with resulting transverse electron beam modula- tion mimicking the lenses pattern. Conventionally, square MLAs are used for UV laser beam shaping, and generated electron beam patterns form square beamlet arrays. The MLA setup can be placed on a rotational mount, thereby rotating electron beam distribution. In combination with transverse-to-longitudinal emittance exchange (EEX) beam line, it allows to vary beamlets horizontal projection and tune electron bunch train.

Shared risk aversion in spontaneous and induced abortion.

2016-05-01

Does the incidence of spontaneous abortion correlate positively over conception cohorts with the incidence of non-clinically indicated induced abortion as predicted by shared risk aversion? We find that the number of spontaneous and non-clinically indicated induced abortions correlates in conception cohorts, suggesting that risk aversion affects both the conscious and non-conscious mechanisms that control parturition. Much literature speculates that natural selection conserved risk aversion because the trait enhanced Darwinian fitness. Risk aversion, moreover, supposedly influences all decisions including those that individuals can and cannot report making. We argue that these circumstances, if real, would manifest in conscious and non-conscious decisions to invest in prospective offspring, and therefore affect incidence of induced and spontaneous abortion over time. Using data from Denmark, we test the hypothesis that monthly conception cohorts yielding unexpectedly many non-clinically indicated induced abortions also yield unexpectedly many spontaneous abortions. The 180 month test period (January 1995 through December 2009), yielded 1 351 800 gestations including 156 780 spontaneous as well as 233 280 induced abortions 9100 of which were clinically indicated. We use Box-Jenkins transfer functions to adjust the incidence of spontaneous and non-clinically indicated induced abortions for autocorrelation (including seasonality), cohort size, and fetal as well as gestational anomalies over the 180-month test period. We use cross-correlation to test our hypothesized association. We find a positive association between spontaneous and non-clinically indicated induced abortions. This suggests, consistent with our theory, that mothers of conception cohorts that yielded more spontaneous abortions than expected opted more frequently than expected for non-clinically indicated induced abortion. Limitations of our work include that even the world's best registration system will not capture all spontaneous abortions and that results may not generalize beyond Denmark. Our findings imply that abortion, intentional or 'spontaneous,' follows from a woman's estimate, made consciously or otherwise, of the costs and benefits of extending gestation given characteristics of the prospective offspring, likely environmental circumstances at birth, and maternal resources.

A Muslim woman in her sixteenth week of pregnancy was informed that her ultrasound scan showed spina bifida, and laboratory results confirmed the diagnosis. The child would have various complications and, most probably, would need medical care for life. With the consent of her husband she decided to terminate the pregnancy. Her decision sparked controversy among Muslim clerics in her community, sparking debate between those who would allow abortion for medical reasons and those who oppose abortion for any reason. This paper will review the philosophical and theological arguments of the pro-life and pro-choice groups as well as the Islamic perspective concerning a woman’s autonomy over her reproductive system, the sanctity of the fetus and the embryo, therapeutic abortion, and ensoulment.

Evaluation of bovine abortion cases and tissue suitability for identification of infectious agents in California diagnostic laboratory cases from 2007 to 2012.

Establishing a definitive cause of bovine abortion is a challenging problem faced by veterinary practitioners and diagnosticians. Detection of an infectious or noninfectious source for abortion may facilitate interventions that mitigate future fetal loss in the herd. The purposes of this study were to identify the most common causes of bovine abortion in cases submitted to the California Animal Health and Food Safety Laboratory System, Davis (CAHFS) from 2007 to 2013 and to determine if detection of infectious pathogens differed with the fetal tissue evaluated. Records of 665 bovine abortion cases of 709 animals were reviewed for pathologic diagnoses, test methods used to identify causative conditions, and which tissues yielded successful identification of infectious agents associated with abortion. Over 58% of abortions were attributed to an infectious cause and 46.9% had an infectious agent identified. The most common infectious conditions were Epizootic Bovine Abortion (EBA) (16.2% of all fetuses), other fetal bacterial infections (14.7% of all fetuses), and Neospora caninum (9.3% of all fetuses.) The bacterium associated with EBA (currently named Pajaroellobacter abortibovis) was most commonly identified by immunohistochemistry (IHC) in lymphoid organs (thymus and spleen); N. caninum IHC was most frequently positive in brain, kidney, and placenta. In cases of pathogenic and opportunistic bacterial infections, abomasal samples yielded a significantly greater proportion of definitive aerobic culture results than lung or liver tissues. Direct fluorescent antibody test results for Bovine Viral Diarrhea Virus testing were identical between lung and kidney tissues and nearly identical (96.0%) for Bovine Herpesvirus I. Noninfectious abortive conditions included fetal stress (10.5%), dystocia (3.9%), congenital defects (3.3%), toxicological or mineral problems (1.8%), and death of the cow (1.1%). Just over 20% of the aborted fetuses had no gross or histopathological lesions to explain the abortion. This review highlights the need for submission of critical samples including abomasal contents, lymphoid tissues (thymus, spleen, and lymph nodes), and brain to maximize the diagnosticians' ability to identify causes of abortion.

Based on research conducted in 2012, we estimate the cost to the Rwandan health-care system of providing post-abortion care (PAC) due to unsafe abortions, a subject of policy importance not studied before at the national level. Thirty-nine public and private health facilities representing three levels of health care were randomly selected for data collection from key care providers and administrators for all five regions. Using an ingredients approach to costing, data were gathered on drugs, supplies, material, personnel time and hospitalization. Additionally, direct non-medical costs such as overhead and capital costs were also measured. We found that the average annual PAC cost per client, across five types of abortion complications, was $93. The total cost of PAC nationally was estimated to be $1.7 million per year, 49% of which was expended on direct non-medical costs. Satisfying all demands for PAC would raise the national cost to $2.5 million per year. PAC comprises a significant share of total expenditure in reproductive health in Rwanda. Investing more resources in provision of contraceptive services to prevent unwanted or mistimed pregnancies would likely reduce health systems costs. PMID:24548846

Incorrect knowledge of laws may affect how women enter the health system or seek services, and it likely contributes to the disconnect between official laws and practical applications of the laws that influence women's access to safe, legal abortion services. To provide a synthesis of evidence of women's awareness and knowledge of the legal status of abortion in their country, and the accuracy of women's knowledge on specific legal grounds and restrictions outlined in a country's abortion law. A systematic search was carried for articles published between 1980-2015. Quantitative, mixed-method data collection, and objectives related to women's awareness or knowledge of the abortion law was included. Full texts were assessed, and data extraction done by a single reviewer. Final inclusion for analysis was assessed by two reviewers. The results were synthesised into tables, using narrative synthesis. Of the original 3,126 articles, and 16 hand searched citations, 24 studies were included for analysis. Women's correct general awareness and knowledge of the legal status was less than 50% in nine studies. In six studies, knowledge of legalization/liberalisation ranged between 32.3%-68.2%. Correct knowledge of abortion on the grounds of rape ranged from 12.8%-98%, while in the case of incest, ranged from 9.8%-64.5%. Abortion on the grounds of fetal impairment and gestational limits, varied widely from 7%-94% and 0%-89.5% respectively. This systematic review synthesizes literature on women's awareness and knowledge of the abortion law in their own context. The findings show that correct general awareness and knowledge of the abortion law and legal grounds and restrictions amongst women was limited, even in countries where the laws were liberal. Thus, interventions to disseminate accurate information on the legal context are necessary.

One hundred and forty Cheviot and 100 Suffolk cross Mule primiparous 1-2-year-old ewes, from a flock of about 700 ewes, were vaccinated with an attenuated live 1B strain Chlamydia abortus vaccine about 4 weeks before ram introduction (September 2011). Between 08 March and 01 April 2012, 50 2-year-old ewes aborted and 29 of these died, despite antimicrobial and anti-inflammatory treatment and supportive care. Seven fetuses and three placentae from five 2-year-old ewes were submitted for pathological investigation. The aborted fetuses showed stages of autolysis ranging from being moderately fresh to putrefaction. Unusual, large multifocal regions of thickened membranes, with a dull red granular surface and moderate amounts of grey-white surface exudate were seen on each of the placentae. Intracellular, magenta-staining, acid fast inclusions were identified in Ziehl Neelsen-stained placental smears. Immunohistochemistry for Chlamydia-specific lipopolysaccharide showed extensive positive labelling of the placental epithelia. Molecular analyses of the aborted placentae demonstrated the presence of the 1B vaccine-type strain of C. abortus and absence of any wild-type field strain. The vaccine strain bacterial load of the placental tissue samples was consistent with there being an association between vaccination and abortion. Initial laboratory investigations resulted in a diagnosis of chlamydial abortion. Further investigations led to the identification of the 1B vaccine strain of C. abortus in material from all three of the submitted aborted placentae. Timely knowledge and understanding of any potential problems caused by vaccination against C. abortus are prerequisites for sustainable control of chlamydial abortion. This report describes the investigation of an atypical abortion storm in sheep, and describes the identification of the 1B vaccine strain of C. abortus in products of abortion. The significance of this novel putative association between the vaccine strain of C. abortus and severe clinical disease is unknown. Aspects of the approach that is described are relevant to the investigation of all outbreaks of ovine abortion, irrespective of the diagnosis. Awareness of the changing role of C. abortus as a major global cause of abortion ought to reinforce the importance of monitoring of adequate biosecurity in those countries which are currently free from chlamydial abortion.
Evaluation of a multi-pronged intervention to improve access to safe abortion care in two districts in Jharkhand

2014-01-01

Background Despite the adoption of the Medical Termination of Pregnancy Act in 1972, access to safe abortion services remains limited in India. Awareness of the legality of abortion also remains low, leading many women to seek services outside the health system. Medical abortion (MA) is an option that has the potential to expand access to safe abortion services. A multi-pronged intervention covering a population of 161,000 in 253 villages in the Silli and Khunti blocks of Jharkhand was conducted between 2007 and 2009, seeking to improve medical abortion services and create awareness at the community level by providing information through community intermediaries and creating an enabling environment through a behavior change communication campaign. The study evaluates the changes in knowledge about abortion-related issues, changes in abortion care-seeking, and service utilization as a result of this intervention. Methods A baseline cross-sectional survey was conducted pre-intervention (n = 1,253) followed by an endline survey (n = 1,290) one year after the completion of the intervention phase. In addition, monitoring data from intervention facilities was collected monthly over the study period. Results Nearly 85% of respondents reported being exposed to safe abortion messaging as a result of the intervention. Awareness of the legality of abortion increased significantly from 19.7% to 57.6% for women, as did awareness of the specific conditions for which abortion is allowed. Results were similar for men. There was also a significant increase in the proportion of men and women who knew of a legal and safe provider and place from where abortion services could be obtained. Multivariate analysis showed positive associations between exposure to any component of the intervention and increased knowledge about legality and gestational age limits, however only interpersonal communication was associated with a significant increase in knowledge of where to obtain safe services (OR 4.8, SE 0.67). Utilization of safe abortion services, and in particular MA, increased at all intervention sites over the duration of the intervention with a shift towards women seeking care earlier in pregnancy. Conclusion The evaluation demonstrates the success of the intervention and its potential for replication in similar contexts within India. PMID:24886273

Modern secular bioethics has focused on developing a set of universal principles to guide clinical decision making. However, this ignores the important role of religion in resolving bioethical questions. It is imperative that health-care providers understand these belief systems in order to traverse value conflicts and provide the highest quality care to a diverse population. This paper focuses on the process of bioethical deliberation in Judaism, Catholicism, and Islam. Abortion is normatively prohibited in each faith and through examining how each ethical code allows for abortion when the mother’s life is in peril due to the fetus, we highlight the value of unborn life in each faith. Orthodox Judaism uses the concept of rodef, or pursuer, to permit abortion in this scenario, Catholicism uses the moral concept of “double effect,” while Islamic law cites the maqāṣid, higher objectives of the law, to permit abortion in this scenario.

Abortion is the interruption of a dynamic process in a final and irreversible form. The legalization of abortion is applied to human ontogenesis, that is, the development of the human being. However, the embryo that is growing in the uterus is not a human being because a human being is a complex organism with differentiated systems, its own identity and intrinsic autonomy in its process of development. There are basically four levels of the analysis of the problem of abortion: 1) fundamental emotional arguments; 2) profound ignorance of technical and scientific facts; 3) rational positions obfuscated by the dramatic intensity of everyday situations; and 4) the conjunction of deliberated position where culpability is avoided with solidarity for all subjects of the process with a socially oriented view. The phenomenon of abortion from an epidemiological point of view summons the facts with which it is associated: poverty, illiteracy, shortage or lack of community health resources, absence of centers for adolescents, degradation of the environment, and precariousness of employment.

While several studies have documented the prevalence of unprotected pre-marital sex among young people in India, little work has explored one of its likely consequences, unintended pregnancy and abortion. This paper examines the experiences of 26 unmarried young abortion-seekers (aged 15-24) interviewed in depth as part of a larger study of unmarried abortion-seekers at clinics run by an NGO in Bihar and Jharkhand. Findings reveal that recognition of the unintended pregnancy was delayed for many and many who suspected so further delayed acknowledging it. Once recognised, most confided in the partner and, for the most part, partners were supportive; a significant minority, including those who had experienced forced sex, did not have partner support and delayed the abortion until the second trimester of pregnancy. Family support was absent in most cases; where provided, it was largely to protect the family reputation. Finally, unsuccessful attempts to terminate the pregnancy were made by several young women, often with the help of partners or family member. Findings call for programmes for young women and men, their potential partners, parents and families and the health system that will collectively enable unmarried young women to obtain safe abortions in a supportive environment.

Crew Exploration Vehicle Ascent Abort Trajectory Analysis and Optimization

The Orion Crew Exploration Vehicle is the first crewed capsule design to be developed by NASA since Project Apollo. Unlike Apollo, however, the CEV is being designed for service in both Lunar and International Space Station missions. Ascent aborts pose some issues that were not present for Apollo, due to its launch azimuth, nor Space Shuttle, due to its cross range capability. The requirement that a North Atlantic splashdown following an abort be avoidable, in conjunction with the requirement for overlapping abort modes to maximize crew survivability, drives the thrust level of the service module main engine. This paper summarizes 3DOF analysis conducted by NASA to aid in the determination of the appropriate propulsion system for the service module, and the appropriate propellant loading for ISS missions such that crew survivability is maximized.

Can the need of subsequent abortion be reduced by providing intrauterine contraception as a part of the abortion service? Provision of intrauterine devices (IUDs) in association with first trimester abortion more than halved the incidence of repeat abortion during the first year of follow-up. Following abortion, the incidence of subsequent abortion is high, up to 30-40%. In cohort studies, intrauterine contraception has reduced the need of repeat abortion by 60-70%. A randomized controlled trial. The main outcome measure was the incidence of subsequent induced abortions during the follow-up. Altogether 751 women seeking first trimester induced abortion were recruited and randomized into two groups. Randomization was accomplished by computer-assisted permuted-block randomization with random block sizes of four to six. The investigators did not participate in randomization, which was done before commencing the study. The participants were recruited between 18 October 2010 and 21 January 2013. The inclusion criteria were age ≥18 years, duration of pregnancy ≤12 weeks, accepting intrauterine contraception, residence in Helsinki and signing the informed consent form. Women with contraindications to intrauterine contraception, such as uterine anomaly, acute genital infection or pap-smear change requiring surgical treatment were ineligible to participate.This study was conducted in collaboration between the Department of Obstetrics and Gynaecology, University of Helsinki and Helsinki University Hospital, and Centralized family planning of the City of Helsinki.The intervention group (n = 375) was provided with intrauterine contraception (either the levonorgestrel-releasing intrauterine system or copper-releasing intrauterine device) immediately following surgical abortion (18.1%) or at a follow-up 2-4 weeks after medical abortion (81.9%). Women in the control group were prescribed oral contraceptives and advised to contact their primary healthcare unit for a follow-up visit and further contraceptive services according to national guidelines. The women were followed-up to 28 February 2014 by using the Finnish National Abortion Registry, Helsinki University Hospital electronic database and clinical follow-up visit at 1 year. The median age of the whole study group was 27 years and 44% had a history of induced abortion(s). During the follow-up year the number of women requesting subsequent abortion was significantly lower in the intervention than in the control group (9/375 [2.4%] versus 20/373 [5.4%], difference -3.0 [95% CI -6.0 to -0.2] percentage points, P = 0.038, according to intention-to-treat analysis and 5/346 [1.4%] versus 20/357 [5.6%], difference -4.2(-7.2 to -1.4) percentage points, P = 0.003, according to per-protocol analysis, respectively). Provision of intrauterine contraception was safe with rate of infection and expulsion similar to those reported previously. The power calculation was calculated for a 5-year follow-up. However, significant differences between the two groups were already seen after 1 year. The present study was performed in a single clinic, where, ∼15% of all abortions in Finland are performed. In order to decrease the need of subsequent abortions, IUDs should be provided at the time of abortion. The study was registered at www.clinicaltrials.gov (NCT01223521). 18 October 2010. 18 October 2010. © The Author 2015.

Recurrent miscarriage is defined as the loss of 3 or more consecutive pregnancies; however, the underlying immunologic mechanisms that trigger pregnancy loss remain largely unelucidated. Galectin-9 (Gal-9) may modulate a variety of biologic functions and play an important role in Th1/Th2 immune deviation. To analyze the mechanism of Gal-9 in abortion, we used the classical abortion-prone mouse model (DBA/2-mated CBA/J mice) to detect the expression of Gal-9 at the maternal-fetal interface. We also mimicked the immune environment of pregnancy by culturing trophoblast cells with peripheral blood mononuclear cells (PBMCs) to explore how Gal-9 might be involved in the pathogenesis of abortion. We found that the expression levels of Gal-9 in abortion-prone matings were lower than that for controls. Using a coculture system, we detected a Th1 preponderance in the coculture from abortion-prone matings. Furthermore, Gal-9 blockade augmented the imbalance of Th1/Th2 immunity in abortion-prone matings by promoting the secretion of Th1-derived cytokines in coculture, while there was a Th2 preponderance when we administered recombinant Gal-9. In conclusion, our results suggest that the Gal-9 signal is important for the regulation of PBMC function toward a Th2 bias at the maternal-fetal interface, which is beneficial for the maintenance of a normal pregnancy.

2013-01-01

A new Differential and errant Beam Current Monitor (DBCM) is being implemented for both the Spallation Neutron Source's Medium Energy Beam Transport (MEBT) and the Super Conducting Linac (SCL) accelerator sections. These new current monitors will abort the beam when the difference between two toroidal pickups exceeds a threshold. The MEBT DBCM will protect the MEBT chopper target, while the SCL DBCM will abort beam to minimize fast beam losses in the SCL cavities. The new DBCM will also record instances of errant beam, such as beam dropouts, to assist in further optimization of the SNS Accelerator. A software Errantmore » Beam Monitor was implemented on the regular BCM hardware to study errant beam pulses. The new system will take over this functionality and will also be able to abort beam on pulse-to-pulse variations. Because the system is based on the FlexRIO hardware and programmed in LabVIEW FPGA, it will be able to abort beam in about 5 us. This paper describes the development, implementation, and initial test results of the DBCM, as well as errant beam examples.« less

The development and use of an interactive environment to perform control system design and analysis of the proposed Crew Exploration Vehicle Launch Abort System is described. The environment, built using a commercial dynamic systems design package, includes use of an open-source configuration control software tool and a collaborative wiki to coordinate between the simulation developers, control law developers and users. A method for switching between multiple candidate control laws and vehicle configurations is described. Aerodynamic models, especially in a development program, change rapidly, so a means for automating the implementation of new aerodynamic models is described.
The Orion Pad Abort 1 Flight Test A Highly Successful Test

NASA Technical Reports Server (NTRS)

Sinclair, Robert; Taylor, Anthony P. (Tony); Johnston, Justin

2011-01-01

The Orion Pad Abort 1 (PA-1) flight test was designed as an early demonstration of the Launch Abort System (LAS) for the Orion capsule. The LAS was designed developed and manufactured by the Lockheed Martin/Orbital Sciences team. At inception it was realized that recovery of the Orion Capsule simulator would be useful from an engineering analysis and data recovery point of view. Additionally this test represented a flight opportunity for the Orion parachute system, which in a real abort would provide final landing deceleration. The Orion parachute program is named CPAS (CEV Parachute Assembly System). Thus CPAS became a part of the PA-1 flight, as a secondary test objective. At program kick off, the CPAS system was in the design state described below. Airbag land landing of the spacecraft was the program baseline. This affected the rigging of the parachutes. The system entry deployment conditions and vehicle mass have both evolved since that original design. It was decided to use the baseline CPAS Generation 1 (Gen 1) parachute system for the recovery of the PA-1 flight. As CPAS was a secondary test objective, the system would be delivered in its developmental state. As the PA-1 program evolved, the parachute recovery system (CPAS) moved from a secondary objective to a more important portion of the program. Tests were added, weights and deployment conditions changed and some hardware portions of the CPAS configuration were not up to the new challenges. Additional tests were added to provide confidence in the developmental system. This paper will review a few of these aspects with the goal of showing some preliminary and qualitative results from what we believe was a highly successful test.

Based on research conducted in 2012, we estimate the cost to the Rwandan health-care system of providing post-abortion care (PAC) due to unsafe abortions, a subject of policy importance not studied before at the national level. Thirty-nine public and private health facilities representing three levels of health care were randomly selected for data collection from key care providers and administrators for all five regions. Using an ingredients approach to costing, data were gathered on drugs, supplies, material, personnel time and hospitalization. Additionally, direct non-medical costs such as overhead and capital costs were also measured. We found that the average annual PAC cost per client, across five types of abortion complications, was $93. The total cost of PAC nationally was estimated to be $1.7 million per year, 49% of which was expended on direct non-medical costs. Satisfying all demands for PAC would raise the national cost to $2.5 million per year. PAC comprises a significant share of total expenditure in reproductive health in Rwanda. Investing more resources in provision of contraceptive services to prevent unwanted or mistimed pregnancies would likely reduce health systems costs.

First amendment challenges to the use of mandatory student fees for abortion services have not reached federal courts, and the only pertinent state decision upheld the mandatory fee system. However, recent decisions and historical analysis suggest the court must grant relief to students whose right to free worship is violated. (Author/MSE)
Misperceptions about the risks of abortion in women presenting for abortion.

Misinformation about the risks and sequelae of abortion is widespread. The purpose of this study was to examine whether women having an abortion who believe that there should be restrictions to abortion (i.e., that some other women should not be allowed to have an abortion) also believe this misinformation about the health risks associated with abortion. We carried out a cross-sectional survey of women presenting consecutively for an abortion at an urban abortion clinic in Vancouver, British Columbia, between February and September 2012. Of 1008 women presenting for abortion, 978 completed questionnaires (97% response rate), and 333 of these (34%) favoured abortion restrictions. More women who favoured restrictions believed that the health risk of an abortion was the same as or greater than the health risk of childbirth (84.2% vs. 65.6%, P < 0.001), that abortion caused mental health problems (39.1% vs. 28.3%, P < 0.001), and that abortion caused infertility (41.7% vs. 21.9%, P < 0.001). Using multivariate logistic regression analyses, believing that abortion should not be restricted was found to be a significantly correlated with correct answers about health risks, mental health problems, and infertility. Misinformed beliefs about the risks of abortion are common among women having an abortion. Women presenting for abortion who favoured restrictions to abortion have more misperceptions about abortion risks than women who favour no restrictions.
Sensitivity Analysis of Launch Vehicle Debris Risk Model

NASA Technical Reports Server (NTRS)

Gee, Ken; Lawrence, Scott L.

2010-01-01

As part of an analysis of the loss of crew risk associated with an ascent abort system for a manned launch vehicle, a model was developed to predict the impact risk of the debris resulting from an explosion of the launch vehicle on the crew module. The model consisted of a debris catalog describing the number, size and imparted velocity of each piece of debris, a method to compute the trajectories of the debris and a method to calculate the impact risk given the abort trajectory of the crew module. The model provided a point estimate of the strike probability as a function of the debris catalog, the time of abort and the delay time between the abort and destruction of the launch vehicle. A study was conducted to determine the sensitivity of the strike probability to the various model input parameters and to develop a response surface model for use in the sensitivity analysis of the overall ascent abort risk model. The results of the sensitivity analysis and the response surface model are presented in this paper.
Abortion rate during the second half of gestation of cows undergoing surgery in lateral recumbency as compared with cows of a control population.

Hirsbrunner, G; Knutti, B; Eicher, R

1999-01-01

In a retrospective study, we compared the abortion rates of 59 cows in the second half of gestation, admitted to the Clinic for Food Animals and Horses (1993-1996) with a strictly focal problem (head region, udder and teats, locomotor system) requiring surgery in lateral recumbency, to the abortion rate of a control cow population. Before surgery, a uterus relaxant was given in 42 cases, and 17 cows were untreated as to pregnancy. Cows included in the reproduction health program of the Department of Fertility and Reproduction were used as a control population. Data of 1,736 cows pregnant in the second half of gestation per year were available for the same time period (1993-1996). Abortion rate was 5.08% for the cows undergoing surgery in lateral recumbency as compared with 5.18% for the cows of the control population. There was no significant difference between the two populations (P > 0.05). Thus, the risk for abortion in the cows in question is not elevated as compared with the control population.

Unsafe abortion is one of the greatest neglected problems of health care in developing countries like Pakistan. In countries where abortions are restricted women have to resort to clandestine interventions to have an unwanted pregnancy terminated. The study was conducted to find out the prevalence of septic induced abortion and the associated morbidity and mortality and to highlight the measures to reduce it. This cross-sectional descriptive study was carried out in Obs/Gyn B Unit, Ayub Teaching Hospital, Abbottabad from January 2007 to December 2011. During this period all the patients presenting with pyrexia lower abdominal pain, vaginal bleeding, acute abdomen, septic or hypovolaemic shock after undergoing some sort of intervention for abortion outside the hospital were included. After thorough history, examination and detailed investigations including high vaginal and endocervical swabs for culture and sensitivity and pelvic ultrasound supportive management was given followed by antibiotics, surgical evacuation of uterus/ major laparotomy in collaboration with surgeon as required. Patients with DIC or multiple system involvement were managed in High Dependency Unit (HDU) by multidisciplinary team. During the study period out of a total 6,906 admissions 968 presented with spontaneous abortion. There were 110 cases (11.36%) of unsafe abortion, 56.4% presented with vaginal discharge, 34.5% with vaginal bleeding, 21.8% with acute abdomen, while 18.9% in shock and 6.8% with DIC. Forty-nine percent patients used termination as a method of contraception. Mortality rate was 16.36%, leading cause being septicaemia. Death and severe morbidity from unsafe abortions and its complications is avoidable through health education, effective contraception, early informed recognition and management of the problem once it occurs.

Demand for abortion and post abortion care in Ibadan, Nigeria.

PubMed

Awoyemi, Bosede O; Novignon, Jacob

2014-01-01

While induced abortion is considered to be illegal and socially unacceptable in Nigeria, it is still practiced by many women in the country. Poor family planning and unsafe abortion practices have daunting effects on maternal health. For instance, Nigeria is on the verge of not meeting the Millennium development goals on maternal health due to high maternal mortality ratio, estimated to be about 630 maternal deaths per 100,000 live births. Recent evidences have shown that a major factor in this trend is the high incidence of abortion in the country. The objective of this paper is, therefore, to investigate the factors determining the demand for abortion and post-abortion care in Ibadan city of Nigeria. The study employed data from a hospital-based/exploratory survey carried out between March to September 2010. Closed ended questionnaires were administered to a sample of 384 women of reproductive age from three hospitals within the Ibadan metropolis in South West Nigeria. However, only 308 valid responses were received and analysed. A probit model was fitted to determine the socioeconomic factors that influence demand for abortion and post-abortion care. The results showed that 62% of respondents demanded for abortion while 52.3% of those that demanded for abortion received post-abortion care. The findings again showed that income was a significant determinant of abortion and post-abortion care demand. Women with higher income were more likely to demand abortion and post-abortion care. Married women were found to be less likely to demand for abortion and post-abortion care. Older women were significantly less likely to demand for abortion and post-abortion care. Mothers' education was only statistically significant in determining abortion demand but not post-abortion care demand. The findings suggest that while abortion is illegal in Nigeria, some women in the Ibadan city do abort unwanted pregnancies. The consequence of this in the absence of proper post-abortion care is daunting. There is the need for policymakers to intensify public education against indiscriminate abortion and to reduce unwanted pregnancies. In effect, there is need for effective alternative family planning methods. This is likely to reduce the demand for abortion. Further, with income found as a major constraint, post abortion services should be made accessible to both the rich and poor alike so as to prevent unnecessary maternal deaths as a result of abortion related complications.
Women’s Awareness and Knowledge of Abortion Laws: A Systematic Review

2016-01-01

Background Incorrect knowledge of laws may affect how women enter the health system or seek services, and it likely contributes to the disconnect between official laws and practical applications of the laws that influence women’s access to safe, legal abortion services. Objective To provide a synthesis of evidence of women’s awareness and knowledge of the legal status of abortion in their country, and the accuracy of women’s knowledge on specific legal grounds and restrictions outlined in a country’s abortion law. Methods A systematic search was carried for articles published between 1980–2015. Quantitative, mixed-method data collection, and objectives related to women’s awareness or knowledge of the abortion law was included. Full texts were assessed, and data extraction done by a single reviewer. Final inclusion for analysis was assessed by two reviewers. The results were synthesised into tables, using narrative synthesis. Results Of the original 3,126 articles, and 16 hand searched citations, 24 studies were included for analysis. Women’s correct general awareness and knowledge of the legal status was less than 50% in nine studies. In six studies, knowledge of legalization/liberalisation ranged between 32.3% - 68.2%. Correct knowledge of abortion on the grounds of rape ranged from 12.8% – 98%, while in the case of incest, ranged from 9.8% - 64.5%. Abortion on the grounds of fetal impairment and gestational limits, varied widely from 7% - 94% and 0% - 89.5% respectively. Conclusion This systematic review synthesizes literature on women’s awareness and knowledge of the abortion law in their own context. The findings show that correct general awareness and knowledge of the abortion law and legal grounds and restrictions amongst women was limited, even in countries where the laws were liberal. Thus, interventions to disseminate accurate information on the legal context are necessary. PMID:27010629

In Peru, abortion is legal only to preserve the life and health of the woman. A non-profit clinic system in Peru implemented a harm-reduction model for women with unwanted pregnancy that included pre-abortion care with instructions about misoprostol use and post-abortion care; they started offering telephone follow-up for clients in 2011. This study aimed to evaluate the effectiveness and safety of the harm-reduction model, and to compare outcomes by type of follow-up obtained. Between January 2012 and March 2013, 500 adult women seeking harm-reduction services were recruited into the study. Telephone surveys were conducted approximately four weeks after their initial harm-reduction counseling session with 262 women (response rate 52%); 9 participants were excluded. The survey focused on whether women pursued an abortion, and if so, what their experience was. Demographic and clinical data were also extracted from clinic records. Eighty-six percent of participants took misoprostol; among those taking misoprostol, 89% reported a complete abortion at the time of the survey. Twenty-two percent obtained an aspiration after taking misoprostol and 8% self-reported adverse events including hemorrhage without transfusion, infection, or severe pain. Among women who took misoprostol, 46% reported receiving in-person follow-up (in some cases both telephone and in-person), 34% received telephone only, and 20% did not report receiving any form of follow-up. Those who had in-person follow-up with the counselor were most likely to report a complete abortion (<0.001). Satisfaction with both types of follow-up was very high, with 81%-89% reporting being very satisfied. Liberalization of restrictive abortion laws is associated with improvements in health outcomes, but the process of legal reform is often lengthy. In the interim, giving women information about evidence-based regimens of misoprostol, as well as offering a range of follow-up options to ensure high quality post-abortion care, may reduce the risks associated with unsafe abortion.
Use of Heated Helium to Simulate Surface Pressure Fluctuations on the Launch Abort Vehicle During Abort Motor Firing

Panda, Jayanta; James, George H.; Burnside, Nathan J.; Fong, Robert; Fogt, Vincent A.

2011-01-01

The solid-rocket plumes from the Abort motor of the Multi-Purpose Crew Vehicle (MPCV, also know as Orion) were simulated using hot, high pressure, Helium gas to determine the surface pressure fluctuations on the vehicle in the event of an abort. About 80 different abort situations over a wide Mach number range, (0.3< or =M< or =1.2) and vehicle attitudes (+/-15deg) were simulated inside the NASA Ames Unitary Plan, 11-Foot Transonic Wind Tunnel. For each abort case, typically two different Helium plume and wind tunnel conditions were used to bracket different flow matching critera. This unique, yet cost-effective test used a custom-built hot Helium delivery system, and a 6% scale model of a part of the MPCV, known as the Launch Abort Vehicle. The test confirmed the very high level of pressure fluctuations on the surface of the vehicle expected during an abort. In general, the fluctuations were found to be dominated by the very near-field hydrodynamic fluctuations present in the plume shear-layer. The plumes were found to grow in size for aborts occurring at higher flight Mach number and altitude conditions. This led to an increase in the extent of impingement on the vehicle surfaces; however, unlike some initial expectations, the general trend was a decrease in the level of pressure fluctuations with increasing impingement. In general, the highest levels of fluctuations were found when the outer edges of the plume shear layers grazed the vehicle surface. At non-zero vehicle attitudes the surface pressure distributions were found to become very asymmetric. The data from these wind-tunnel simulations were compared against data collected from the recent Pad Abort 1 flight test. In spite of various differences between the transient flight situation and the steady-state wind tunnel simulations, the hot-Helium data were found to replicate the PA1 data fairly reasonably. The data gathered from this one-of-a-kind wind-tunnel test fills a gap in the manned-space programs, and will be used to establish the acoustic environment for vibro-acoustic qualification testing of the MPCV.

2015-05-03

In recent RHIC operational runs, planned and unplanned pre-fire triggered beam aborts have been observed that resulted in quenches of SC main ring magnets, indicating a weakened magnet kick strength due to beam-induced ferrite heating. An improvement program was initiated to reduce the longitudinal coupling impedance with changes to the ferrite material and the eddy-current strip geometry. Results of the impedance measurements and of magnet heating tests with CMD10 ferrite up to 190°C are reported. All 10 abort kickers in the tunnel have been modified and were provided with a cooling system for the RUN 15.
Patient Information Websites About Medically Induced Second-Trimester Abortions: A Descriptive Study of Quality, Suitability, and Issues

Axelsson, Ove

2017-01-01

Background Patients undergoing medically induced second-trimester abortions feel insufficiently informed and use the Web for supplemental information. However, it is still unclear how people who have experience with pregnancy termination appraise the quality of patient information websites about medically induced second-trimester abortions, whether they consider the websites suitable for patients, and what issues they experience with the websites. Objective Our objective was to investigate the quality of, suitability of, and issues with patient information websites about medically induced second-trimester abortions and potential differences between websites affiliated with the health care system and private organizations. Methods We set out to answer the objective by using 4 laypeople who had experience with pregnancy termination as quality assessors. The first 50 hits of 26 systematic searches were screened (N=1300 hits) using search terms reported by the assessors. Of these hits, 48% (628/1300) were irrelevant and 51% (667/1300) led to websites about medically induced second-trimester abortions. After correcting for duplicate hits, 42 patient information websites were included, 18 of which were affiliated with the health care system and 24 with private organizations. The 4 assessors systematically assessed the websites with the DISCERN instrument (total score range 16-80), the Ensuring Quality Information for Patients (EQIP) tool (total score range 0-100), as well as questions concerning website suitability and perceived issues. Results The interrater reliability was 0.8 for DISCERN and EQIP, indicating substantial agreement between the assessors. The total mean score was 36 for DISCERN and 40 for EQIP, indicating poor overall quality. Websites from the health care system had greater total EQIP (45 vs 37, P>.05) and reliability scores (22 vs 20, P>.05). Only 1 website was recommended by all assessors and 57% (24/42) were rated as very unsuitable by at least one assessor. The most reported issues with the websites involved lack of information (76%, 32/42), and poor design (36%, 15/42). Conclusions The high number of irrelevant hits and poor quality of patient information websites are considerable issues that must be addressed and considered when consulting patients awaiting medically induced second-trimester abortions. In clinical encounters, health professionals should initiate discussions concerning websites about medically induced second-trimester abortions and inform patients about the issues and quality deficits associated with these websites.

Demand for abortion and post abortion care in Ibadan, Nigeria

PubMed Central

2014-01-01

Background While induced abortion is considered to be illegal and socially unacceptable in Nigeria, it is still practiced by many women in the country. Poor family planning and unsafe abortion practices have daunting effects on maternal health. For instance, Nigeria is on the verge of not meeting the Millennium development goals on maternal health due to high maternal mortality ratio, estimated to be about 630 maternal deaths per 100,000 live births. Recent evidences have shown that a major factor in this trend is the high incidence of abortion in the country. The objective of this paper is, therefore, to investigate the factors determining the demand for abortion and post-abortion care in Ibadan city of Nigeria. Methods The study employed data from a hospital-based/exploratory survey carried out between March to September 2010. Closed ended questionnaires were administered to a sample of 384 women of reproductive age from three hospitals within the Ibadan metropolis in South West Nigeria. However, only 308 valid responses were received and analysed. A probit model was fitted to determine the socioeconomic factors that influence demand for abortion and post-abortion care. Results The results showed that 62% of respondents demanded for abortion while 52.3% of those that demanded for abortion received post-abortion care. The findings again showed that income was a significant determinant of abortion and post-abortion care demand. Women with higher income were more likely to demand abortion and post-abortion care. Married women were found to be less likely to demand for abortion and post-abortion care. Older women were significantly less likely to demand for abortion and post-abortion care. Mothers’ education was only statistically significant in determining abortion demand but not post-abortion care demand. Conclusion The findings suggest that while abortion is illegal in Nigeria, some women in the Ibadan city do abort unwanted pregnancies. The consequence of this in the absence of proper post-abortion care is daunting. There is the need for policymakers to intensify public education against indiscriminate abortion and to reduce unwanted pregnancies. In effect, there is need for effective alternative family planning methods. This is likely to reduce the demand for abortion. Further, with income found as a major constraint, post abortion services should be made accessible to both the rich and poor alike so as to prevent unnecessary maternal deaths as a result of abortion related complications.

Malaysia has relatively liberal abortion laws in that they permit abortions for both physical and mental health cases. However, abortion remains a taboo subject. The stagnating contraceptive prevalence rate combined with the plunging fertility rate suggests that abortion might be occurring clandestinely. This qualitative study aimed to explore the experiences of women and their needs with regard to abortion. Women from diverse backgrounds were purposively selected from an urban family planning clinic in Penang, Malaysia based on inclusion criteria of being aged 21 and above and having experienced an induced abortion. A semi-structured interview guide consisting of open ended questions eliciting women's experiences and needs with regard to abortion were utilized to facilitate the interviews. Audio recordings were transcribed verbatim and analyzed thematically. Thirty-one women, with ages ranging from 21-43 years (mean 30.16 ± 6.41), who had induced surgical/medical abortions were recruited from an urban family planning clinic. Ten women reported only to have had one previous abortion while the remaining had multiple abortions ranging from 2-8 times. The findings revealed that although women had abortions, nevertheless they faced problems in seeking for abortion information and services. They also had fears about the consequences and side effects of abortion and wish to receive more information on abortion. Women with post-abortion feelings ranged from no feelings to not wanting to think about the abortion, relief, feeling of sadness and loss. Abortion decisions were primarily theirs but would seek partner/husband's agreement. In terms of the women's needs for abortion, or if they wished for more information on abortion, pre and post abortion counseling and post-abortion follow up. The existing abortion laws in Malaysia should enable the government to provide abortion services within the law. Unfortunately, the study findings show that this is generally not so, most probably due to social stigma. There is an urgent need for the government to review its responsibility in providing accessible abortion services within the scope of the law and to look into the regulatory requirements for such services in Malaysia. This study also highlighted the need for educational efforts to make women aware of their reproductive rights and also to increase their reproductive knowledge pertaining to abortion. Besides the government, public education on abortion may also be improved by efforts from abortion providers, advocacy groups and related NGOs.

A gas discharge switch EEV HX3002 is being evaluated at Brookhaven National Laboratory as a possible candidate of RHIC Beam Abort Kicker modulator main switch. At higher beam energy and higher beam intensity, the switch stability becomes very crucial. The hollow anode thyratron used in the existing system is not rated for long reverse current conduction. The reverse voltage arcing caused thyratron hold-off voltage de-rating has been the main limitation of the system operation. To improve the system reliability, a new type of gas discharge switch has been suggested by Marconi Applied Technology for its reverse conducting capability.

Abortion is the termination of pregnancy that occurs spontaneously or purposely. In the most developed world, abortion is legally allowed for women seeking safe termination of pregnancies. Particularly, when access to legal abortion is restricted, abortion is the resort to unsafe methods. The aim of this review is to necessitate safe abortion and to accentuate the consequences of illegal abortion in case of legal prohibition. We used Pubmed, MedLine and Scopus databases to review previous literatures of safe, unsafe, legal and illegal abortions. Research work and reports from organizations such as World Health Organization (WHO), World Bank (WB) and United Nations (UN) were included. Snowball sampling was used to obtain relevant journals. Abortion is conventional whether it is safe, unsafe, legal or illegal. The intention of the antiabortion policy was to reduce the number of abortions globally. However, instead of decreasing rates, evidences show significant increase in abortions. When abortion is legal, the preconditions to be ensured are availability, accessibility, affordability and acceptability for the safe abortion facilities. When abortion is illegal, risk reduction strategies are needed to decrease maternal morbidity and mortality. We can reduce abortion related morbidity and mortality, whether it is legal or illegal if we can ensure the appropriate access to health care, including abortion services, education on sexuality, access to contraceptives, post abortion care, and suitable interventions and liberalization of laws. The paper reviewed the Mexico City Policy and the US foreign aid strategies and highlighted the evidence based analysis for policy reform. The liberalized abortion law can save pregnant women from abortion related complications and death.
The incidence of abortion worldwide.

Accurate measurement of induced abortion levels has proven difficult in many parts of the world. Health care workers and policymakers need information on the incidence of both legal and illegal induced abortion to provide the needed services and to reduce the negative impact of unsafe abortion on women's health. Numbers and rates of induced abortions were estimated from four sources: official statistics or other national data on legal abortions in 57 countries; estimates based on population surveys for two countries without official statistics; special studies for 10 countries where abortion is highly restricted; and worldwide and regional estimates of unsafe abortion from the World Health Organization. Approximately 26 million legal and 20 million illegal abortions were performed worldwide in 1995, resulting in a worldwide abortion rate of 35 per 1,000 women aged 15-44. Among the subregions of the world, Eastern Europe had the highest abortion rate (90 per 1,000) and Western Europe to the lowest rate (11 per 1,000). Among countries where abortion is legal without restriction as to reason, the highest abortion rate, 83 per 1,000, was reported for Vietnam and the lowest, seven per 1,000, for Belgium and the Netherlands. Abortion rates are no lower overall in areas where abortion is generally restricted by law (and where many abortions are performed under unsafe conditions) than in areas where abortion is legally permitted. Both developed and developing countries can have low abortion rates. Most countries, however, have moderate to high abortion rates, reflecting lower prevalence and effectiveness of contraceptive use. Stringent legal restrictions do not guarantee a low abortion rate.

Characterization of the launch abort system of the Multi-purpose Crew Vehicle (MPCV) for control design and accurate simulation has provided a significant challenge to aerodynamicists and design engineers. The design space of the launch abort vehicle (LAV) includes operational altitudes from ground level to approximately 300,000 feet, Mach numbers from 0-9, and peak dynamic pressure near 1300psf during transonic flight. Further complicating the characterization of the aerodynamics and the resultant vehicle controllability is the interaction of the vehicle flowfield with the plumes of the two solid propellant motors that provide attitude control and the main propulsive impulse for the LAV. These interactions are a function of flight parameters such as Mach number, altitude, dynamic pressure, vehicle attitude, as well as parameters relating to the operation of the motors themselves - either as a function of time for the AM, or as a result of the flight control system requests for control torque from the ACM. This paper discusses the computational aerodynamic modeling of the aerodynamic interaction caused by main abort motor and the attitude control motor of the MPCV LAV, showing the effects of these interactions on vehicle controllability.

Biochemical research of biological systems is highly developed, and it has disclosed a spectrum of chemical reactions, genetic processes, and the pathological development of various diseases. The fundamental hypothesis of physical processes in biological systems, in particular of coherent electrically polar vibrations and electromagnetic activity, was formulated by H. Fröhlich he assumed connection of cancer process with degradation of coherent electromagnetic activity. But the questions of cellular structures capable of the coherent electrical polar oscillation, mechanisms of energy supply, and the specific role of the endogenous electromagnetic fields in transport, organisation, interactions, and information transfer remained open. The nature of physical disturbances caused by some diseases (including the recurrent abortion in humans and the cancer) was unknown. We have studied the reasons of recurrent abortions in humans by means of the cell mediated immunity (using immunologic active RNA prepared from blood of inbred laboratory mice strain C3H/H2K, infected with the lactate dehydrogenase elevating virus-LD V) and the cytogenetic examination from karyotype pictures. The recurrent abortion group contained women with dg. spontaneous abortion (n = 24) and the control group was composed of 30 healthy pregnant women. Our hypothesis was related to quality of endometrium in relation to nidation of the blastocyst. The energetic insufficiency (ATP) inhibits normal development of fetus and placenta. We hope that these ideas might have impact on further research, which could provide background for effective interdisciplinary cooperation of malignant and non-malignant diseases.

Unwed pregnancy among adolescents is a disturbing event in Indian belief-systems, and very young motherhood limits girls' social, economic and educational prospects. Girls who seek abortions are always at higher risk for delay in care seeking; this paper looks at the reasons why. It reports the experiences of 34 unmarried adolescent girls and young women, aged 10-24 years, who obtained induced abortion from a tertiary care abortion clinic over a period of seven months in 2004. Ten were below 19 years of age, the rest were 20-24 years. Only eight of the 34 pregnancies were <12 weeks. The reasons for delay were fear of disclosure, lack of any support system and scarcity of resources. In 30 cases, the decision to terminate was made jointly with family members, especially the mother. Only half knew about contraception, of whom two used condoms. Only two of the partners accompanied the girl to the abortion clinic and another two offered some financial support. Because of the conflict between wanting to have sex and feeling guilty about it, these young people experienced terrible distress in the course of unwanted pregnancy. Comparing the adolescents who attended the clinic in 2004 with those we have seen in 2012-2013, the paper shows that as regards the essentials, much has remained the same.

2015-01-01

This paper describes a quantitative methodology for bounding the false positive (FP) and false negative (FN) probabilities associated with a human-rated launch vehicle abort trigger (AT) that includes sensor data qualification (SDQ). In this context, an AT is a hardware and software mechanism designed to detect the existence of a specific abort condition. Also, SDQ is an algorithmic approach used to identify sensor data suspected of being corrupt so that suspect data does not adversely affect an AT's detection capability. The FP and FN methodologies presented here were developed to support estimation of the probabilities of loss of crew and loss of mission for the Space Launch System (SLS) which is being developed by the National Aeronautics and Space Administration (NASA). The paper provides a brief overview of system health management as being an extension of control theory; and describes how ATs and the calculation of FP and FN probabilities relate to this theory. The discussion leads to a detailed presentation of the FP and FN methodology and an example showing how the FP and FN calculations are performed. This detailed presentation includes a methodology for calculating the change in FP and FN probabilities that result from including SDQ in the AT architecture. To avoid proprietary and sensitive data issues, the example incorporates a mixture of open literature and fictitious reliability data. Results presented in the paper demonstrate the effectiveness of the approach in providing quantitative estimates that bound the probability of a FP or FN abort determination.

To evaluate Chinese healthcare providers' knowledge regarding medical abortion, to understand provider preferences for abortion methods, and to investigate the role of remuneration on providers' decision making. Between November 2009 and May 2010, 658 abortion service providers from family-planning service centers and hospitals in Shenzhen and Henan, China, were surveyed via self-administered questionnaires. The knowledge score (out of a maximum of 32) regarding medical abortion was 16-20 for 60.9% of the providers; 20.4% of the providers preferred medical abortion to surgical abortion, whereas 35.0% preferred surgical abortion. Overall, 72.2% of providers stated that they did not receive any commission for providing medical abortion or surgical abortion. Most healthcare providers believed that surgical abortion was preferable to medical abortion. Efforts should be made to overcome the perceived disadvantages of medical abortion.

Leahy, Frank B.

2003-01-01

A study was conducted to determine the quality of thermodynamic and wind data measured by or derived from the Transatlantic Abort Landing (TAL) Atmospheric Sounding System (TASS). The system has Global Positioning System (GPS) tracking capability and includes a helium-filled latex balloon that carries an instrument package (sonde) and various ground equipment that receives and processes the data from the sonde. TASS is used to provide vertical profiles of thermodynamic and low-resolution wind data in support of Shuttle abort landing operations at TAL sites. TASS uses GPS to determine height, wind speed, and wind direction. The TASS sonde has sensors that directly measure air temperature and relative humidity. These are then used to derive air pressure and density. Test flights were conducted where a TASS sonde and a reference sonde were attached to the same balloon and the two profiles were compared. The objective of the testing was to determine if TASS thermodynamic and wind data met Space Shuttle Program (SSP) accuracy requirements outlined in the Space Shuttle Launch and Landing Program Requirements Document (PRD).

Economic hardship accompanying large recessions can lead families to terminate unplanned pregnancies. To assess whether abortions have risen during the recession, we collected crude abortion data from 2000 to 2012 from Eurostat for countries that had legal abortions and complete data. Declining trends in abortion ratios between 2000 and 2009 have been reversing. Excess abortions between 2010 and 2012 totaled 10.6 abortions per 1000 pregnancies ending in abortion or birth or 6701 additional abortions (95% CI 1190–9240) with stronger effects in younger ages. Economic shocks may increase recourse to abortion. Further research should explore causal pathways and protective factors. PMID:27009038

The individual level cost of pregnancy termination in Zambia: a comparison of safe and unsafe abortion.

2016-09-01

Zambia has one of the most liberal abortion laws in sub-Saharan Africa. However, rates of unsafe abortion remain high with negative health and economic consequences. Little is known about the economic burden on women of abortion care-seeking in low income countries. The majority of studies focus on direct costs (e.g. hospital fees). This article estimates the individual-level economic burden of safe and unsafe abortion care-seeking in Zambia, incorporating all indirect and direct costs. It uses data collected in 2013 from a tertiary hospital in Lusaka, (n = 112) with women who had an abortion. Three treatment routes are identified: (1) safe abortion at the hospital, (2) unsafe clandestine medical abortion initiated elsewhere with post-abortion care at the hospital and (3) unsafe abortion initiated elsewhere with post-abortion care at the hospital. Based on these three typologies, we use descriptive analysis and linear regression to estimate the costs for women of seeking safe and unsafe abortion and to establish whether the burden of abortion care-seeking costs is equally distributed across the sample. Around 39% of women had an unsafe abortion, incurring substantial economic costs before seeking post-abortion care. Adolescents and poorer women are more likely to use unsafe abortion. Unsafe abortion requiring post-abortion care costs women 27% more than a safe abortion. When accounting for uncertainty this figure increases dramatically. For safe and unsafe abortions, unofficial provider payments represent a major cost to women.This study demonstrates that despite a liberal legislation, Zambia still needs better dissemination of the law to women and providers and resources to ensure abortion service access. The policy implications of this study include: the role of pharmacists and mid-level providers in the provision of medical abortion services; increased access to contraception, especially for adolescents; and elimination of demands for unofficial provider payments. © The Author 2016.

The incidence of induced abortion in Kinshasa, Democratic Republic of Congo, 2016.

2017-01-01

In the Democratic Republic of Congo, the penal code prohibits the provision of abortion. In practice, however, it is widely accepted that the procedure can be performed to save the life of a pregnant woman. Although abortion is highly restricted, anecdotal evidence indicates that women often resort to clandestine abortions, many of which are unsafe. However, to date, there are no official statistics or reliable data to support this assertion. Our study provides the first estimates of the incidence of abortion and unintended pregnancy in Kinshasa. We applied the Abortion Incidence Complications Method (AICM) to estimate the incidence of abortion and unintended pregnancy. We used data from a Health Facilities Survey and a Prospective Morbidity Survey to determine the annual number of women treated for abortion complications at health facilities. We also employed data from a Health Professionals Survey to calculate a multiplier representing the number of abortions for every induced abortion complication treated in a health facility. In 2016, an estimated 37,865 women obtained treatment for induced abortion complications in health facilities in Kinshasa. For every woman treated in a facility, almost four times as many abortions occurred. In total, an estimated 146,713 abortions were performed, yielding an abortion rate of 56 per 1,000 women aged 15-49. Furthermore, more than 343,000 unintended pregnancies occurred, resulting in an unintended pregnancy rate of 147 per 1,000 women aged 15-49. Increasing contraceptive uptake can reduce the number of women who experience unintended pregnancies, and as a consequence, result in fewer women obtaining unsafe abortions, suffering abortion complications, and dying needlessly from unsafe abortion. Increasing access to safe abortion and improving post-abortion care are other measures that can be implemented to reduce unsafe abortion and/or its negative consequences, including maternal mortality.

Although abortion care has been an established routine since decades in India, 8% of maternal mortality is attributed to unsafe abortion. Increased knowledge and improved attitudes among health care providers have a potential to reduce barriers to safe abortion care by reducing stigma and reluctance to provide abortion. Previous research has shown that medical students' attitudes can predict whether they will perform abortions. The objective of our study was to explore attitudes toward abortion among medical interns in Maharastra, India. A cross-sectional survey was carried out among 1996 medical interns in Maharastra, India. Descriptive and analytical statistics were used to interpret the study instrument. Almost one quarter of the respondents considered abortion to be morally wrong, one fifth did not find abortions for unmarried women acceptable and one quarter falsely believed that a woman needs her partner or spouse's approval to have an abortion. Most participants agreed that unsafe abortion is a serious health problem in India. A majority of the respondents rated their knowledge of sexual and reproductive health as good, but only 13% had any clinical practice in abortion care services. Disallowing attitudes toward abortion and misconceptions about the legal regulations were common among the surveyed medical students. Knowledge and attitudes toward abortion among future physicians could be improved by amendments to the medical education, potentially increasing the number of future providers delivering safe and legal abortion services. Abortion is legal in India since decades, but maternal mortality due to unsafe abortions remains high. This survey of attitudes toward abortion among medical interns in Maharastra indicates that disallowing views prevail. Improved knowledge and clinical training can increase numbers of potential abortion providers, thus limit unsafe abortion. Copyright © 2014 Elsevier Inc. All rights reserved.

Abstract Background: Medical abortion with mifepristone and misoprostol was introduced in Norway in 1998, and since then there has been an almost complete change from predominantly surgical to medical abortions. We aimed to describe the medical abortion implementation process, and to compare characteristics of women obtaining medical and surgical abortion. Methods: Information from all departments of obstetrics and gynaecology in Norway on the time of implementation of medical abortion and abortion procedures in use up to 12 weeks of gestation was assessed by surveys in 2008 and 2012. We also analysed data from the National Abortion Registry comprising 223 692 women requesting abortion up to 12 weeks of gestation during 1998–2013. Results: In 2012, all hospitals offered medical abortion, 84.4% offered medical abortion at 9–12 weeks of gestation and 92.1% offered home administration of misoprostol. The use of medical abortion increased from 5.9% of all abortions in 1998 to 82.1% in 2013. Compared with women having a surgical abortion, women obtaining medical abortion had higher odds for undergoing an abortion at 4–6 weeks (adjusted OR 2.33; 95% confidence interval 2.28-2.38). Waiting time between registered request for an abortion until termination was reduced from 11.3 days in 1998 to 7.3 days in 2013. Conclusions: Norwegian women have gained access to more treatment modalities and simplified protocols for medical abortion. At the same time they obtained abortions at an earlier gestational age and the waiting time has been reduced. PMID:28031316

Factors such as poverty, stigma, lack of knowledge about the legal status of abortion, and geographical distance from a provider may prevent women from accessing safe abortion services, even where abortion is legal. Data on the consequences of abortion denial outside of the US, however, are scarce. In this article we present data from studies among women seeking legal abortion services in four countries (Colombia, Nepal, South Africa and Tunisia) to assess sociodemographic characteristics of legal abortion seekers, as well as the frequency and reasons that women are denied abortion care. The proportion of women denied abortion services and the reasons for which they were denied varied widely by country. In Colombia, 2% of women surveyed did not receive the abortions they were seeking; in South Africa, 45% of women did not receive abortions on the day they were seeking abortion services. In both Tunisia and Nepal, 26% of women were denied their wanted abortions. The denial of legal abortion services may have serious consequences for women's health and wellbeing. Additional evidence on the risk factors for presenting later in pregnancy, predictors of seeking unsafe illegal abortion, and the health consequences of illegal abortion and childbirth after an unwanted pregnancy is needed. Such data would assist the development of programmes and policies aimed at increasing access to and utilisation of safe abortion services where abortion is legal, and harm reduction models for women who are unable to access legal abortion services.

2017-01-01

CONTEXT National and state-level information about abortion incidence can help inform policies and programs intended to reduce levels of unintended pregnancy. METHODS In 2015–2016, all U.S. facilities known or expected to have provided abortion services in 2013 or 2014 were surveyed. Data on the number of abortions were combined with population data to estimate national and state-level abortion rates. The number of abortion-providing facilities and changes since a similar 2011 survey were also assessed. The number and type of new abortion restrictions were examined in the states that had experienced the largest proportionate changes in clinics providing abortion services. RESULTS In 2014, an estimated 926,200 abortions were performed in the United States, 12% fewer than in 2011; the 2014 abortion rate was 14.6 abortions per 1,000 women aged 15–44, representing a 14% decline over this period. The number of clinics providing abortions declined 6% between 2011 and 2014, and declines were steepest in the Midwest (22%) and the South (13%). Early medication abortions accounted for 31% of nonhospital abortions, up from 24% in 2011. Most states that experienced the largest proportionate declines in the number of clinics providing abortions had enacted one or more new restrictions during the study period, but reductions were not always associated with declines in abortion incidence. CONCLUSIONS The relationship between abortion access, as measured by the number of clinics, and abortion rates is not straightforward. Further research is needed to understand the decline in abortion incidence. PMID:28094905

The aim of this study was to describe and compare contraceptive use, fertility, birth, and abortion rates in the Nordic countries. National data on births, abortions, fertility rate (1975-2013), redeemed prescriptions of hormonal contraceptives and sales figures of copper intrauterine devices (2008-2013) among women 15-49 years of age in the Nordic countries were collected and analyzed. Use of hormonal contraceptives and copper intrauterine devices varied between 31 and 44%. The highest use was in Denmark (39-44%) and Sweden (40-42%). Combined hormonal contraception followed by the levonorgestrel-releasing intrauterine system were the most common methods. During 1975-2013 abortion rates decreased in Denmark (from 27/1000 women to 15/1000 women aged 15-44/1000 women) and Finland (from 20 to 10/1000 women), remained stable in Norway (≈16) and Sweden (≈20) and increased in Iceland (from 6 to 15/1000 women). Birth rates remained stable around 60/1000 women aged 15-44 in all countries except for Iceland where the birth rate decreased from 95 to 65/1000 women. Abortion rates were highest in the age group 20-24 years. In the same age group, Sweden had a lower contraceptive use (51%) compared with Denmark (59%) and Norway (56%) and a higher abortion rate 33/1000 compared with Denmark (25/1000) and Norway (27/1000). In contrast to the declining average fertility and birth rates in Europe, rates in the Nordic countries remain high and stable despite high contraceptive use and liberal access to abortion on women's request. © 2017 Nordic Federation of Societies of Obstetrics and Gynecology.
Estimating the probability of spontaneous abortion in the presence of induced abortion and vice versa.

Hammerslough, C R

1992-01-01

An integrated approach to estimate the total number of pregnancies that begin in a population during one calendar year and the probability of spontaneous abortion is described. This includes an indirect estimate of the number of pregnancies that result in spontaneous abortions. The method simultaneously takes into account the proportion of induced abortions that are censored by spontaneous abortions and vice versa in order to estimate the true annual number of spontaneous and induced abortions for a population. It also estimates the proportion of pregnancies that women intended to allow to continue to a live birth. The proposed indirect approach derives adjustment factors to make indirect estimates by combining vital statistics information on gestational age at induced abortion (from the 12 States that report to the National Center for Health Statistics) with a life table of spontaneous abortion probabilities. The adjustment factors are applied to data on induced abortions from the Alan Guttmacher Institute Abortion Provider Survey and data on births from U.S. vital statistics. For the United States in 1980 the probability of a spontaneous abortion is 19 percent, given the presence of induced abortion. Once the effects of spontaneous abortion are discounted, women in 1980 intended to allow 73 percent of their pregnancies to proceed to a live birth. One medical benefit to a population practicing induced abortion is that induced abortions avert some spontaneous abortions, leading to a lower mean gestational duration at the time of spontaneous abortion.

Prior to legalization of abortion, induced abortions were performed in an illegal manner and that resulted in many complications hence abortion was legalized in India in 1971 and the number of induced abortions has been gradually increasing since then. One way of preventing abortions is to provide family planning services to these abortion seekers so that same is not repeated. The study was performed to find out the acceptance of contraception after abortion. A prospective study was performed over a period of five years from 2010 to 2014. The study group included all the cases reporting for abortion. A proforma was filled in detail to find out the type of contraception being used before pregnancy and acceptance of contraception after abortion. The existing facilities were also evaluated. 1228 abortions were performed over a period of five years. 94.5% of abortions were during the first trimester. 39.9% had not used any contraceptive before, contraceptives used were natural and barrier which had high failure. The main indication for seeking abortion was failure of contraception and completion of family. 39.6% of patients accepted sterilization as a method of contraception. The existing post abortion family planning services are inadequate. Post abortion period is one which is important to prevent subsequent abortions and family planning services after abortion need to be strengthened.

Although abortion has been legal under broad criteria in Nepal since 2002, a significant proportion of women continue to obtain illegal, unsafe abortions, and no national estimates exist of the incidence of safe and unsafe abortions. Data were collected in 2014 from a nationally representative sample of 386 facilities that provide legal abortions or postabortion care and a survey of 134 health professionals knowledgeable about abortion service provision. Facility caseloads and indirect estimation techniques were used to calculate the national and regional incidence of legal and illegal abortion. National and regional levels of abortion complications and unintended pregnancy were also estimated. In 2014, women in Nepal had 323,100 abortions, of which 137,000 were legal, and 63,200 women were treated for abortion complications. The abortion rate was 42 per 1,000 women aged 15-49, and the abortion ratio was 56 per 100 live births. The abortion rate in the Central region (59 per 1,000) was substantially higher than the national average. Overall, 50% of pregnancies were unintended, and the unintended pregnancy rate was 68 per 1,000 women of reproductive age. Despite legalization of abortion and expansion of services in Nepal, unsafe abortion is still common and exacts a heavy toll on women. Programs and policies to reduce rates of unintended pregnancy and unsafe abortion, increase access to high-quality contraceptive care and expand safe abortion services are warranted.

Exploring pregnancy termination experiences and needs among Malaysian women: A qualitative study

PubMed Central

2012-01-01

Background Malaysia has relatively liberal abortion laws in that they permit abortions for both physical and mental health cases. However, abortion remains a taboo subject. The stagnating contraceptive prevalence rate combined with the plunging fertility rate suggests that abortion might be occurring clandestinely. This qualitative study aimed to explore the experiences of women and their needs with regard to abortion. Methods Women from diverse backgrounds were purposively selected from an urban family planning clinic in Penang, Malaysia based on inclusion criteria of being aged 21 and above and having experienced an induced abortion. A semi-structured interview guide consisting of open ended questions eliciting women’s experiences and needs with regard to abortion were utilized to facilitate the interviews. Audio recordings were transcribed verbatim and analyzed thematically. Results Thirty-one women, with ages ranging from 21–43 years (mean 30.16 ±6.41), who had induced surgical/medical abortions were recruited from an urban family planning clinic. Ten women reported only to have had one previous abortion while the remaining had multiple abortions ranging from 2–8 times. The findings revealed that although women had abortions, nevertheless they faced problems in seeking for abortion information and services. They also had fears about the consequences and side effects of abortion and wish to receive more information on abortion. Women with post-abortion feelings ranged from no feelings to not wanting to think about the abortion, relief, feeling of sadness and loss. Abortion decisions were primarily theirs but would seek partner/husband’s agreement. In terms of the women’s needs for abortion, or if they wished for more information on abortion, pre and post abortion counseling and post-abortion follow up. Conclusions The existing abortion laws in Malaysia should enable the government to provide abortion services within the law. Unfortunately, the study findings show that this is generally not so, most probably due to social stigma. There is an urgent need for the government to review its responsibility in providing accessible abortion services within the scope of the law and to look into the regulatory requirements for such services in Malaysia. This study also highlighted the need for educational efforts to make women aware of their reproductive rights and also to increase their reproductive knowledge pertaining to abortion. Besides the government, public education on abortion may also be improved by efforts from abortion providers, advocacy groups and related NGOs. PMID:22950371
Population Group Abortion Rates and Lifetime Incidence of Abortion: United States, 2008-2014.

To assess the prevalence of abortion among population groups and changes in rates between 2008 and 2014. We used secondary data from the Abortion Patient Survey, the American Community Survey, and the National Survey of Family Growth to estimate abortion rates. We used information from the Abortion Patient Survey to estimate the lifetime incidence of abortion. Between 2008 and 2014, the abortion rate declined 25%, from 19.4 to 14.6 per 1000 women aged 15 to 44 years. The abortion rate for adolescents aged 15 to 19 years declined 46%, the largest of any group. Abortion rates declined for all racial and ethnic groups but were larger for non-White women than for non-Hispanic White women. Although the abortion rate decreased 26% for women with incomes less than 100% of the federal poverty level, this population had the highest abortion rate of all the groups examined: 36.6. If the 2014 age-specific abortion rates prevail, 24% of women aged 15 to 44 years in that year will have an abortion by age 45 years. The decline in abortion was not uniform across all population groups.

Unsafe abortion has been a significant cause of maternal morbidity and mortality in Nepal. Since legalization in 2002, more than 1,200 providers have been trained and 487 sites have been certified for the provision of safe abortion services. Little is known about health care workers' views on abortion legalization, such as their perceptions of women seeking abortion and the implications of legalization for abortion-related health care. To complement a quantitative study of the health effects of abortion legalization in Nepal, we conducted 35 in-depth interviews with physicians, nurses, counsellors and hospital administrators involved in abortion care and post-abortion complication treatment services at four major government hospitals. Thematic analysis techniques were used to analyze the data. Overall, participants had positive views of abortion legalization - many believed the severity of abortion complications had declined, contributing to lower maternal mortality and morbidity in the country. A number of participants indicated that the proportion of women obtaining abortion services from approved health facilities was increasing; however, others noted an increase in the number of women using unregulated medicines for abortion, contributing to rising complications. Some providers held negative judgments about abortion patients, including their reasons for abortion. Unmarried women were subject to especially strong negative perceptions. A few of the health workers felt that the law change was encouraging unmarried sexual activity and carelessness around pregnancy prevention and abortion, and that repeat abortion was becoming a problem. Many providers believed that although patients were less fearful than before legalization, they remained hesitant to disclose a history of induced abortion for fear of judgment or mistreatment. Providers were generally positive about the implications of abortion legalization for the country and for women. A focus on family planning and post-abortion counselling may be welcomed by providers concerned about multiple abortions. Some of the negative judgments of women held by providers could be tempered through values-clarification training, so that women are supported and comfortable sharing their abortion history, improving the quality of post-abortion treatment of complications.

60% of more than 2000 women surveyed by the Picker Institute who underwent induced abortion procedures rated the quality of their care as excellent. Another third reported their care as being either very good or good. The survey also found that the quality of abortion care is comparable to other outpatient surgery. However, the high quality of care women receive from abortion providers is lost in the hostile anti-abortion climate created by threatening protesters outside of clinics and the murder of 7 clinic workers and physicians who performed abortions. Abortion opponents fail to acknowledge that legal abortion is a medical procedure which protects women's health and saves their lives. Before abortion was legalized in the US, countless women were either rendered unable to reproduce or died from abortion-related complications. Efforts to outlaw abortion persist despite it being widely recognized by medical experts as one of the most safe medical procedures currently performed in the US. When state legislatures target abortion providers with unduly strict regulations, abortion becomes prohibitively expensive and difficult to obtain.
Abortion trends from 1996 to 2011 in Estonia: special emphasis on repeat abortion

2014-01-01

Background The study aimed to describe the overall and age-specific trends of induced abortions from 1996 to 2011 with an emphasis on socio-demographic characteristics and contraceptive use of women having had repeat abortions in Estonia. Methods Data were retrieved from the Estonian Medical Birth and Abortion Registry and Statistics Estonia. Total induced abortion numbers, rates, ratios and age-specific rates are presented for 1996–2011. The percentage change in the number of repeat abortions within selected socio-demographic subgroups, contraception use and distribution of induced abortions among Estonians and non-Estonians for the first, second, third, fourth and subsequent abortions were calculated for the periods 1996–2003 and 2004–2011. Results Observed trends over the 16-year study period indicated a considerable decline in induced abortions with a reduction in abortion rate of 57.1%, which was mainly attributed to younger cohorts. The percentage of women undergoing repeat abortions fell steadily from 63.8% during 1996–2003 to 58.0% during 2004–2011. The percentage of women undergoing repeat abortions significantly decreased over the 16 years within all selected socio-demographic subgroups except among women with low educational attainment and students. Within each time period, a greater percentage of non-Estonians than Estonians underwent repeat abortions and obtained third and subsequent abortions. Most women did not use any contraceptive method prior to their first or subsequent abortion. Conclusion A high percentage of women obtaining repeat abortions reflects a high historical abortion rate. If current trends continue, a rapid decline in repeat abortions may be predicted. To decrease the burden of sexual ill health, routine contraceptive counselling, as standard care in the abortion process, should be seriously addressed with an emphasis on those groups - non-Estonians, women with lower educational attainment, students and women with children - vulnerable with respect to repeat abortion.

Background In 2010–2014, approximately 86% of abortions took place in low- and middle-income countries (LMICs). Although abortion incidence varies minimally across geographical regions, it varies widely by subregion and within countries by subgroups of women. Differential abortion levels stem from variation in the level of unintended pregnancies and in the likelihood that women with unintended pregnancies obtain abortions. Objectives To examine the characteristics of women obtaining induced abortions in LMICs. Methods We use data from official statistics, population-based surveys, and abortion patient surveys to examine variation in the percentage distribution of abortions and abortion rates by age at abortion, marital status, parity, wealth, education, and residence. We analyze data from five countries in Africa, 13 in Asia, eight in Europe, and two in Latin America and the Caribbean (LAC). Results Women across all sociodemographic subgroups obtain abortions. In most countries, women aged 20–29 obtained the highest proportion of abortions, and while adolescents obtained a substantial fraction of abortions, they do not make up a disproportionate share. Region-specific patterns were observed in the distribution of abortions by parity. In many countries, a higher fraction of abortions occurred among women of high socioeconomic status, as measured by wealth status, educational attainment, and urban residence. Due to limited data on marital status, it is unknown whether married or unmarried women make up a larger share of abortions. Conclusions These findings help to identify subgroups of women with disproportionate levels of abortion, and can inform policies and programs to reduce the incidence of unintended pregnancies; and in LMICs that have restrictive abortion laws, these findings can also inform policies to minimize the consequences of unsafe abortion and motivate liberalization of abortion laws. Program planners, policymakers, and advocates can use this information to improve access to safe abortion services, postabortion care, and contraceptive services. PMID:28355285
An overview of medical abortion for clinical practice.

Medical abortion is a safe, convenient, and effective method for terminating an early unintended pregnancy. Medical abortion can be performed up to 63 days from the last menstrual period and may even be used up to 70 days for women who prefer medical abortion over surgical abortion. Counseling on the adverse effects and expectations for medical abortion is critical to success. Medical abortion can be performed in a clinic without special equipment, and it is perceived as more "natural" than a surgical abortion by many women. Follow-up for medical abortion can be simplified to include only serum human chorionic gonadotropin measurements when necessary, although obtaining an ultrasound remains the criterion standard. Pain associated with medical abortion is best treated with nonsteroidal anti-inflammatory medications, possibly in combination with opioid analgesics. Medical abortion can contribute to continuity of care for women who wish to remain with their primary care providers for management of their abortion.
'It's a very complicated issue here': understanding the limited and declining use of manual vacuum aspiration for postabortion care in Malawi: a qualitative study.

Malawi has one of the highest maternal mortality ratios in the world. Unsafe abortions are an important contributor to Malawi's maternal mortality and morbidity, where abortion is illegal except to save the woman's life. Postabortion care (PAC) aims to reduce adverse consequences of unsafe abortions, in part by treating incomplete abortions. Although global and national PAC policies recommend manual vacuum aspiration (MVA) for treatment of incomplete abortion, usage in Malawi is low and appears to be decreasing, with sharp curettage being used in preference. There is limited evidence regarding what influences rejection of recommended PAC innovations. Hence, drawing on Greenhalgh et al. 's (2004. Diffusion of innovations in service organizations: systematic review and recommendations. Milbank Quarterly 82: 581-629.) diffusion of healthcare innovation framework, this qualitative study aimed to investigate factors contributing to the limited and declining use of MVA in Malawi. Semi-structured interviews with 17 PAC providers in a central hospital and a district hospital indicate that a range of factors coalesce and influence PAC and MVA use in Malawi. Factors pertain to four main domains: the system (shortages of material and human resources; lack of training, supervision and feedback), relationships (power dynamics; expected job roles), the health workers (attitudes towards abortion and PAC; prioritization of PAC) and the innovation (perceived risks and benefits of MVA use). Effective and sustainable PAC policy must adopt a broader people-centred health systems approach which considers all these factors, their interactions and the wider socio-cultural, legal and political context of abortion and PAC. The study showed the value of using Greenhalgh et al. 's (2004. Diffusion of innovations in service organizations: systematic review and recommendations. Milbank Quarterly 82: 581-629.) framework to consider the complex interaction of factors surrounding innovation use (or lack of), but provided more insights into rejections of innovations and, particularly, a low- and middle-income country perspective. © The Author 2016.

The 2005 expansion of the Ethiopian abortion law provided minors access to legal abortions, yet little is known about abortion among adolescents. This paper estimates the incidence of legal and clandestine abortions and the severity of abortion-related complications among adolescent and nonadolescent women in Ethiopia in 2014. This paper uses data from three surveys: a Health Facility Survey (n = 822) to collect data on legal abortions and postabortion complications, a Health Professionals Survey (n = 82) to estimate the share of clandestine abortions that resulted in treated complications, and a Prospective Data Survey (n = 5,604) to collect data on abortion care clients. An age-specific variant of the Abortion Incidence Complications Method was used to estimate abortions by age-group. Adolescents have the lowest abortion rate among all women below age 35 (19.6 per 1,000 women). After adjusting for lower levels of sexual activity among adolescents however, we find that adolescents have the highest abortion rate among all age-groups. Adolescents also have the highest proportion (64%) of legal abortions compared with other age-groups. We find no differences in the severity of abortion-related complications between adolescent and nonadolescent women. We find no evidence that adolescents are more likely than older women to have clandestine abortions. However, the higher abortion and pregnancy rates among sexually active adolescents suggest that they face barriers in access to and use of contraceptive services. Further work is needed to address the persistence of clandestine abortions among adolescents in a context where safe and legal abortion is available.

Abortion surveillance--United States, 1992.

From 1980 through 1992, the number of legal induced abortions reported to the CDC remained stable, varying each year by < or = 5%. This report summarizes and reviews information reported to CDC regarding legal induced abortions obtained in the United States during 1992. This report also includes recently reported abortion-related deaths for 1988-1991 and an update on abortion-related deaths for 1985-1987. For each year since 1969, CDC has compiled abortion data received from 52 reporting areas (i.e., the 50 states, the District of Columbia, and New York City). In 1992, 1,359,145 abortions were reported--a 2.1% decrease from 1991. The abortion ratio was 335 legal induced abortions per 1,000 live births, and the abortion rate was 23 per 1,000 women 15-44 years of age. Women who were undergoing an abortion were more likely to be young, white, and unmarried; most had had no previous live births and were obtaining an abortion for the first time. More than half (51%) of all abortions were performed at or before the 8th week of gestation, and 87% were before the 13th week. Approximately 14% of abortions were performed at < or = 6 weeks of gestation, 15% were performed at 7 weeks of gestation, and 22% at 8 weeks of gestation. Younger women (i.e., women < or = 19 years of age) were more likely to obtain abortions later in pregnancy than were older women. Sixteen deaths in 1988, 12 deaths in 1989, and five deaths in 1990 were associated with legal induced abortion. The case-fatality rates for 1988, 1989, and 1990, respectively, were 1.2, 0.9, and 0.3 abortion-related deaths per 100,000 legal induced abortions. Since 1980, the number and rate of abortions have remained relatively stable, with only small year-to-year fluctuations of < or = 5%. However, since 1987, the abortion-to-live-birth ratio has declined; in 1992, the abortion ratio was the lowest recorded since 1977. More pregnant women have been opting to carry their pregnancies to term rather than choosing to have an abortion. As in previous years, deaths associated with legal induced abortions occurred rarely (i.e., one or fewer deaths per 100,000 legal induced abortions). The number and characteristics of women who obtain abortions in the United States should continue to be monitored so that efforts to prevent unintended pregnancy can be assessed and the preventable causes of morbidity and mortality associated with abortions can be identified and reduced.

ComGeom2, a tool developed to generate Common Geometry representation for multidisciplinary analysis, has been used to create a large set of geometries for use in a design study requiring analysis by two computational codes. This paper describes the process used to generate the large number of configurations and suggests ways to further automate the process and make it more efficient for future studies. The design geometry for this study is the launch abort system of the NASA Crew Launch Vehicle.

The detailed abort sequence trees for the reference zirconium hydride (ZrH) reactor power module that have been generated for each phase of the reference Space Base program mission are presented. The trees are graphical representations of causal sequences. Each tree begins with the phase identification and the dichotomy between success and failure. The success branch shows the mission phase objective as being achieved. The failure branch is subdivided, as conditions require, into various primary initiating abort conditions.
Destigmatising abortion: expanding community awareness of abortion as a reproductive health issue in Ghana.

PubMed

Lithur, Nana Oye

2004-04-01

Traditional and cultural values, social perceptions, religious teachings and criminalisation have facilitated stigmatisation of abortion in Ghana. Abortion is illegal in Ghana except in three instances. Though the law allows for performance of abortion in three circumstances, the Ghana reproductive health service policy did not have any induced legal abortion services component to cover the three exceptions until it was revised in 2003. The policy only had 'unsafe and post-abortion' care components, and abortions performed in health facilities operated by the Ghana Health Service were performed under this component. Though the policy has been revised, women and girls who need abortion services in Ghana more often resort to the backstreet dangerous methods and procedures. Criminalisation of abortion and those who perform abortions has contributed to unsafe abortion, the second leading cause of maternal deaths in Ghana. Most of these are performed outside the formal health service structures. Traditionally, abortion is perceived as a shameful act and the community may shun and give a woman who has caused anabortion derogatory names. Would provision of legal abortion services be culturally acceptable within a Ghanaian community? Yes, if they are made aware of the reproductive health benefits of providing safe abortion services. Three major strategies that would help to destigmatise abortion in the community are (1) the liberal interpretation of the three exceptions to the law on abortion; (2) expanding community awareness of its reproductive health benefits; and (3) improving and increasing access to legal abortion services within the formal health facilities.

Rationale Most research in mental health and abortion has examined factors associated with post-abortion psychological health. However, research that follows women from before to after their abortion consistently finds that depressive, anxiety, and stress symptoms are highest just before an abortion compared to any time afterwards. Objective This finding suggests that studies investigating psychosocial factors related to pre-abortion mental health are warranted. Methods The current study uses data from 353 women seeking abortions at three community reproductive health clinics to examine predictors of pre-abortion psychological health. Drawing from three perspectives in the abortion and mental health literature, common risks, stress and coping, and sociocultural context, we conducted multivariable analyses to examine the contribution of important factors on depressive, anxiety, and stress symptoms just before an abortion, including sociodemographics, abortion characteristics, childhood adversities, recent adversities with an intimate partner, relationship context, future pregnancy desires, and perceived abortion stigma. Results Childhood and partner adversities, including reproductive coercion, were associated with negative mental health symptoms, as was perceived abortion stigma. Before perceived abortion stigma was entered into the model, 18.6 %, 20.7 %, and 16.8% of the variance in depressive, anxiety, and stress symptoms respectively, was explained. Perceived abortion stigma explained an additional 13.2 %, 9.7 %, and 10.7 % of the variance in depressive, anxiety, and stress symptoms pre-abortion. Conclusion This study, one of the first to focus on pre-abortion mental health as an outcome, suggests that addressing stigma among women seeking abortions may significantly lower their psychological distress.

Aerodynamic Testing of the Orion Launch Abort Tower Separation with Jettison Motor Jet Interactions

NASA Technical Reports Server (NTRS)

Rhode, Matthew N.; Chan, David T.; Niskey, Charles J.; Wilson, Thomas M.

2011-01-01

The aerodynamic database for the Orion Launch Abort System (LAS) was developed largely from wind tunnel tests involving powered jet simulations of the rocket exhaust plumes, supported by computational fluid dynamics (CFD) simulations. The LAS contains three solid rocket motors used in various phases of an abort to provide propulsion, steering, and Launch Abort Tower (LAT) jettison from the Crew Module (CM). This paper describes a pair of wind tunnel experiments performed at transonic and supersonic speeds to determine the aerodynamic effects due to proximity and jet interactions during LAT jettison from the CM at the end of an abort. The tests were run using two different scale models at angles of attack from 150deg to 200deg , sideslip angles from -10deg to +10deg , and a range of powered thrust levels from the jettison motors to match various jet simulation parameters with flight values. Separation movements between the CM and LAT included axial and vertical translations as well as relative pitch angle between the two bodies. The paper details aspects of the model design, nozzle scaling methodology, instrumentation, testing procedures, and data reduction. Sample data are shown to highlight trends seen in the results.
Launch Vehicle Failure Dynamics and Abort Triggering Analysis

2011-01-01

Launch vehicle ascent is a time of high risk for an on-board crew. There are many types of failures that can kill the crew if the crew is still on-board when the failure becomes catastrophic. For some failure scenarios, there is plenty of time for the crew to be warned and to depart, whereas in some there is insufficient time for the crew to escape. There is a large fraction of possible failures for which time is of the essence and a successful abort is possible if the detection and action happens quickly enough. This paper focuses on abort determination based primarily on data already available from the GN&C system. This work is the result of failure analysis efforts performed during the Ares I launch vehicle development program. Derivation of attitude and attitude rate abort triggers to ensure that abort occurs as quickly as possible when needed, but that false positives are avoided, forms a major portion of the paper. Some of the potential failure modes requiring use of these triggers are described, along with analysis used to determine the success rate of getting the crew off prior to vehicle demise.

Tanzania has one of the highest maternal mortality ratios in the world, and unsafe abortion is one of its leading causes. Yet little is known about its incidence. To provide the first ever estimates of the incidence of unsafe abortion in Tanzania, at the national level and for each of the 8 geopolitical zones (7 in Mainland plus Zanzibar). A nationally representative survey of health facilities was conducted to determine the number of induced abortion complications treated in facilities. A survey of experts on abortion was conducted to estimate the likelihood of women experiencing complications and obtaining treatment. These surveys were complemented with population and fertility data to obtain abortion numbers, rates and ratios, using the Abortion Incidence Complications Methodology. In Tanzania, women obtained just over 405,000 induced abortions in 2013, for a national rate of 36 abortions per 1,000 women age 15-49 and a ratio of 21 abortions per 100 live births. For each woman treated in a facility for induced abortion complications, 6 times as many women had an abortion but did not receive care. Abortion rates vary widely by zone, from 10.7 in Zanzibar to 50.7 in the Lake zone. The abortion rate is similar to that of other countries in the region. Variations by zone are explained mainly by differences in fertility and contraceptive prevalence. Measures to reduce the incidence of unsafe abortion and associated maternal mortality include expanding access to post-abortion care and contraceptive services to prevent unintended pregnancies.

Contraception and induced abortion in the West Indies: a review.

Most islands in the West Indies do not have liberal laws on abortion, nor laws on pregnancy prevention programmes (contraception). We present results of a literature review about the attitude of healthcare providers and women toward (emergency) contraception and induced abortion, prevalence, methods and juridical aspects of induced abortion and prevention policies. Articles were obtained from PubMed, EMBASE, MEDLINE, PsychlNFO and Soclndex (1999 to 2010) using as keywords contraception, induced abortion, termination of pregnancy, medical abortion and West Indies. Thirty-seven articles met the inclusion criteria: 18 on contraception, 17 on induced abortion and two on both subjects. Main results indicated that healthcare providers' knowledge of emergency contraception was low. Studies showed a poor knowledge of contraception, but counselling increased its effective use. Exact numbers about prevalence of abortion were not found. The total annual number of abortions in the West Indies is estimated at 300 000; one in four pregnancies ends in an abortion. The use of misoprostol diminished the complications of unsafe abortions. Legislation of abortion varies widely in the different islands in the West Indies: Cuba, Puerto Rico, Martinique, Guadeloupe and St Martin have legal abortions. Barbados was the first English-speaking island with liberal legislation on abortion. All other islands have restrictive laws. Despite high estimated numbers of abortion, research on prevalence of abortion is missing. Studies showed a poor knowledge of contraception and low use among adolescents. Most West Indian islands have restrictive laws on abortion.

Data of abortion incidence and trends are needed to monitor progress toward improvement of maternal health and access to family planning. To date, estimates of safe and unsafe abortion worldwide have only been made for 1995 and 2003. We used the standard WHO definition of unsafe abortions. Safe abortion estimates were based largely on official statistics and nationally representative surveys. Unsafe abortion estimates were based primarily on information from published studies, hospital records, and surveys of women. We used additional sources and systematic approaches to make corrections and projections as needed where data were misreported, incomplete, or from earlier years. We assessed trends in abortion incidence using rates developed for 1995, 2003, and 2008 with the same methodology. We used linear regression models to explore the association of the legal status of abortion with the abortion rate across subregions of the world in 2008. The global abortion rate was stable between 2003 and 2008, with rates of 29 and 28 abortions per 1000 women aged 15-44 years, respectively, following a period of decline from 35 abortions per 1000 women in 1995. The average annual percent change in the rate was nearly 2·4% between 1995 and 2003 and 0·3% between 2003 and 2008. Worldwide, 49% of abortions were unsafe in 2008, compared to 44% in 1995. About one in five pregnancies ended in abortion in 2008. The abortion rate was lower in subregions where more women live under liberal abortion laws (p<0·05). The substantial decline in the abortion rate observed earlier has stalled, and the proportion of all abortions that are unsafe has increased. Restrictive abortion laws are not associated with lower abortion rates. Measures to reduce the incidence of unintended pregnancy and unsafe abortion, including investments in family planning services and safe abortion care, are crucial steps toward achieving the Millennium Development Goals.

Schiavon, Raffaela; Collado, Maria Elena; Troncoso, Erika; Soto Sánchez, José Ezequiel; Zorrilla, Gabriela Otero; Palermo, Tia

2010-11-01

In 2007, first trimester abortion was legalized in Mexico City, and the public sector rapidly expanded its abortion services. In 2008, to obtain information on the effect of the law on private sector abortion services, we interviewed 135 physicians working in private clinics, located through an exhaustive search. A large majority of the clinics offered a range of reproductive health services, including abortions. Over 70% still used dilatation and curettage (D&C); less than a third offered vacuum aspiration or medical abortion. The average number of abortions per facility was only three per month; few reported more than 10 abortions monthly. More than 90% said they had been offering abortion services for less than 20 months. Many women are still accessing abortion services privately, despite the availability of free or low-cost services at public facilities. However, the continuing use of D&C, high fees (mean of $157-505), poor pain management practices, unnecessary use of ultrasound, general anaesthesia and overnight stays, indicate that private sector abortion services are expensive and far from optimal. Now that abortions are legal, these results highlight the need for private abortion providers to be trained in recommended abortion methods and quality of private abortion care improved.

In 1969, CDC began abortion surveillance to document the number and characteristics of women obtaining legal induced abortions, to monitor unintended pregnancy, and to assist efforts to identify and reduce preventable causes of morbidity and mortality associated with abortions. This report summarizes and reviews information reported to CDC regarding legal induced abortions obtained in the United States in 1997. For each year since 1969, CDC has compiled abortion data by state where the abortion occurred. The data are received from 52 reporting areas in the United States: 50 states, the District of Columbia, and New York City. In 1997, a total of 1,186,039 legal abortions were reported to CDC, representing a 3% decrease from the number reported for 1996. The abortion ratio was 306 legal induced abortions per 1,000 live births, and since 1995, the abortion rate has remained at 20 per 1,000 women aged 15-44 years. The availability of information about characteristics of women who obtained an abortion in 1997 varied by state and by the number of states reporting each characteristic. The total number of legal induced abortions by state is reported by state of residence and state of occurrence; characteristics of women obtaining abortions in 1997 are reported by state of occurrence. Women who were undergoing an abortion were more likely to be young (i.e., aged < 25 years), white, and unmarried; approximately one half were obtaining an abortion for the first time. More than one half of all abortions for which gestational age was reported (55%) were performed at < or = 8 weeks of gestation, and 88% were performed before 13 weeks. Overall, 18% of abortions were performed at the earliest weeks of gestation (< or = 6 weeks), 18% at 7 weeks of gestation, and 20% at 8 weeks of gestation. From 1992 through 1997, increases have occurred in the percentage of abortions performed at the very early weeks of gestation. Few abortions were provided after 15 weeks of gestation--4% of abortions were obtained at 16-20 weeks, and 1.4% were obtained at > or = 21 weeks. A total of 19 reporting areas submitted information regarding abortions performed by medical (nonsurgical) procedures, comprising < 1% of procedures reported by all states. Younger women (i.e., aged < or = 24 years) were more likely to obtain abortions later in pregnancy than were older women. From 1990 through 1995, the number of abortions declined each year; in 1996, the number increased slightly, and in 1997, the number of abortions in the United States declined to it lowest level since 1978. The number and characteristics of women who obtain abortions in the United States should continue to be monitored so that trends in induced abortion can be assessed and efforts to prevent unintended pregnancy can be evaluated.

In 1969, CDC began abortion surveillance to document the number and characteristics of women obtaining legal induced abortions, to monitor unintended pregnancy, and to assist efforts to identify and reduce preventable causes of morbidity and mortality associated with abortions. This report summarizes and reviews information reported to CDC regarding legal induced abortions obtained in the United States in 1998. For each year since 1969, CDC has compiled abortion data by occurrence. From 1973 to 1997, data were received from or estimated for 52 reporting areas in the United States: 50 states, the District of Columbia, and New York City. In 1998, CDC compiled abortion data from only 48 reporting areas; Alaska, California, New Hampshire, and Oklahoma did not report. In 1998, 884,273 legal induced abortions were reported to CDC, representing a 2% decrease from the 900,171 legal induced abortions reported by the same 48 reporting areas for 1997. The abortion ratio, defined as the number of abortions per 1,000 live births, was 264, compared with 274 in 1997 (for the same 48 areas); the abortion rate for these 48 areas was 17 per 1,000 women aged 15-44 years for both 1997 and 1998. The availability of information about characteristics of women who obtained an abortion in 1998 varied by state and by the number of states reporting each characteristic. The total number of legal induced abortions by state is reported by state of residence and state of occurrence; characteristics of women obtaining abortions in 1998 are reported by state of occurrence. Women undergoing an abortion were likely to be young (i.e., age < 25 years), white, and unmarried; slightly more than one half were obtaining an abortion for the first time. Of all abortions for which gestational age was reported, 56% were performed at < or = 8 weeks of gestation, and 88% were performed before 13 weeks. Overall, 19% of abortions were performed at the earliest weeks of gestation (< or = 6 weeks), 18% at 7 weeks, and 19% at 8 weeks. From 1992 (when this information was first collected) through 1998, an increasing percentage of abortions were performed at the very early weeks of gestation. Few abortions were provided after 15 weeks of gestation; 4% were obtained at 16-20 weeks, and 1.4% were obtained at > or = 21 weeks. A total of 24 reporting areas submitted information stating that they performed medical (nonsurgical) procedures (two of these areas categorized medical abortions with "other" procedures), making up < 1% of all procedures reported from all states. From 1993 through 1997 (years for which data have not been published previously and the most recent years for which such data are available), 36 women died as a result of complications from known legal induced abortion, and three deaths were associated with known illegal abortion. The annual case-fatality rate of legal induced abortion ranged from 0.3 to 0.8 abortion-related deaths per 100,000 reported legal induced abortions. From 1990 through 1995, the number of abortions declined each year; in 1996, the number increased slightly, but in 1997, it declined to its lowest level since 1978. In 1998, the number of abortions continued to decrease when comparing the 48 reporting areas. In 1997, as in previous years, deaths related to legal induced abortions occurred rarely. PUBLIC HEALTH ACTIONS TAKEN: The number and characteristics of women who obtain abortions in the United States should continue to be monitored so that trends in induced abortion can be assessed and efforts to prevent unintended pregnancy can be evaluated.
The incidence of induced abortion in Kinshasa, Democratic Republic of Congo, 2016

Background In the Democratic Republic of Congo, the penal code prohibits the provision of abortion. In practice, however, it is widely accepted that the procedure can be performed to save the life of a pregnant woman. Although abortion is highly restricted, anecdotal evidence indicates that women often resort to clandestine abortions, many of which are unsafe. However, to date, there are no official statistics or reliable data to support this assertion. Objectives Our study provides the first estimates of the incidence of abortion and unintended pregnancy in Kinshasa. Methods We applied the Abortion Incidence Complications Method (AICM) to estimate the incidence of abortion and unintended pregnancy. We used data from a Health Facilities Survey and a Prospective Morbidity Survey to determine the annual number of women treated for abortion complications at health facilities. We also employed data from a Health Professionals Survey to calculate a multiplier representing the number of abortions for every induced abortion complication treated in a health facility. Results In 2016, an estimated 37,865 women obtained treatment for induced abortion complications in health facilities in Kinshasa. For every woman treated in a facility, almost four times as many abortions occurred. In total, an estimated 146,713 abortions were performed, yielding an abortion rate of 56 per 1,000 women aged 15–49. Furthermore, more than 343,000 unintended pregnancies occurred, resulting in an unintended pregnancy rate of 147 per 1,000 women aged 15–49. Conclusions Increasing contraceptive uptake can reduce the number of women who experience unintended pregnancies, and as a consequence, result in fewer women obtaining unsafe abortions, suffering abortion complications, and dying needlessly from unsafe abortion. Increasing access to safe abortion and improving post-abortion care are other measures that can be implemented to reduce unsafe abortion and/or its negative consequences, including maternal mortality.

Telling stories about abortion: abortion-related plots in American film and television, 1916-2013.

PubMed

Sisson, Gretchen; Kimport, Katrina

2014-05-01

Popular discourse on abortion in film and television assumes that abortions are under- and misrepresented. Research indicates that such representations influence public perception of abortion care and may play a role in the production of social myths around abortion, with consequences for women's experience of abortion. To date, abortion plotlines in American film and television have not been systematically tracked and analyzed. A comprehensive online search was conducted to identify all representations of pregnancy decision making and abortion in American film and television through January 2013. Search results were coded for year, pregnancy decision and mortality outcome. A total of 310 plotlines were identified, with an overall upward trend over time in the number of representations of abortion decision making. Of these plotlines, 173 (55.8%) resulted in abortion, 80 (25.8%) in parenting, 13 (4.2%) in adoption and 21 (6.7%) in pregnancy loss, and 16 (5.1%) were unresolved. A total of 13.5% (n=42) of stories ended with the death of the woman who considered an abortion, whether or not she obtained one. Abortion-related plotlines occur more frequently than popular discourse assumes. Year-to-year variation in frequency suggests an interactive relationship between media representations, cultural attitudes and policies around abortion regulation, consistent with cultural theory of the relationship between media products and social beliefs. Patterns of outcomes and rates of mortality are not representative of real experience and may contribute to social myths around abortion. The narrative linking of pregnancy termination with mortality is of particular note, supporting the social myth associating abortion with death. This analysis empirically describes the number of abortion-related plotlines in American film and television. It contributes to the systematic evaluation of the portrayal of abortion in popular culture and provides abortion care professionals and advocates with an initial accurate window into cultural stories being told about abortion.

Medical method of abortion (MMA) is a safe, efficient, and affordable method of abortion. However, incomplete abortion is a known side effect. To study incomplete abortion due to medication abortion and compare to spontaneous incomplete abortion and to study referral practices and prescriptions in cases of incomplete abortion following MMA. Prospective observational study of 100 women with first trimester incomplete abortion, divided into two groups (spontaneous or following MMA), was administered a questionnaire which included information regarding onset of bleeding, treatment received, use of medications for abortion, its prescription, and administration. Comparison of two groups was done using Fisher exact test (SPSS 21.0 software). Thirty percent of incomplete abortions were seen following MMA; possible reasons being self-administration or prescription by unregistered practitioners, lack of examination, incorrect dosage and drugs, and lack of follow-up. Complications such as collapse, blood requirement, and fever were significantly higher in these patients compared to spontaneous abortion group. The side effects of incomplete abortions following MMA can be avoided by the following standard guidelines. Self medication, over- the-counter use, and prescription by unregistered doctors should be discouraged and reported, and need of follow-up should be emphasized.

Summary Background Reliable information on the incidence of induced abortion in India is lacking. Official statistics and national surveys provide incomplete coverage. Since the early 2000s, medication abortion has become increasingly available, improving the way women obtain abortions. The aim of this study was to estimate the national incidence of abortion and unintended pregnancy for 2015. Methods National abortion incidence was estimated through three separate components: abortions (medication and surgical) in facilities (including private sector, public sector, and non-governmental organisations [NGOs]); medication abortions outside facilities; and abortions outside of facilities and with methods other than medication abortion. Facility-based abortions were estimated from the 2015 Health Facilities Survey of 4001 public and private health facilities in six Indian states (Assam, Bihar, Gujarat, Madhya Pradesh, Tamil Nadu, and Uttar Pradesh) and from NGO clinic data. National medication abortion drug sales and distribution data were obtained from IMS Health and six principal NGOs (DKT International, Marie Stopes International, Population Services International, World Health Partners, Parivar Seva Santha, and Janani). We estimated the total number of abortions that are not medication abortions and are not obtained in a health facility setting through an indirect technique based on findings from community-based study findings in two states in 2009, with adjustments to account for the rapid increase in use of medication abortion since 2009. The total number of women of reproductive age and livebirth data were obtained from UN population data, and the proportion of births from unplanned pregnancies and data on contraceptive use and need were obtained from the 2015–16 National Family Health Survey-4. Findings We estimate that 15·6 million abortions (14·1 million–17·3 million) occurred in India in 2015. The abortion rate was 47·0 abortions (42·2–52·1) per 1000 women aged 15–49 years. 3·4 million abortions (22%) were obtained in health facilities, 11·5 million (73%) abortions were medication abortions done outside of health facilities, and 0·8 million (5%) abortions were done outside of health facilities using methods other than medication abortion. Overall, 12·7 million (81%) abortions were medication abortions, 2·2 million (14%) abortions were surgical, and 0·8 million (5%) abortions were done through other methods that were probably unsafe. We estimated 48·1 million pregnancies, a rate of 144·7 pregnancies per 1000 women aged 15–49 years, and a rate of 70·1 unintended pregnancies per 1000 women aged 15–49 years. Abortions accounted for one third of all pregnancies, and nearly half of pregnancies were unintended. Interpretation Health facilities can have a greater role in abortion service provision and provide quality care, including post-abortion contraception. Interventions are needed to expand access to abortion services through better equipping existing facilities, ensuring adequate and continuous supplies of medication abortion drugs, and by increasing the number of trained providers. In view of how many women rely on self-administration of medication abortion drugs, interventions are needed to provide women with accurate information on these drugs and follow-up care when needed. Research is needed to test interventions that improve knowledge and practice in providing medication abortion, and the Indian Government at the national and state level needs to prioritise improving policies and practice to increase access to comprehensive abortion care and quality contraceptive services that prevent unintended pregnancy.

Ntontis, Evangelos; Hopkins, Nick

2018-02-27

Social psychological research on activism typically focuses on individuals' social identifications. We complement such research through exploring how activists frame an issue as a social problem. Specifically, we explore anti-abortion activists' representation of abortion and the abortion debate's protagonists so as to recruit support for the anti-abortion cause. Using interview data obtained with UK-based anti-abortion activists (N = 15), we consider how activists characterized women having abortions, pro-abortion campaigners, and anti-abortion campaigners. In particular, we consider the varied ways in which emotion featured in the representation of these social actors. Emotion featured in different ways. Sometimes, it was depicted as constituting embodied testament to the nature of reality. Sometimes, it was depicted as blocking the rational appraisal of reality. Our analysis considers how such varied meanings of emotion shaped the characterization of abortion and the abortion debate's protagonists such that anti-abortion activists were construed as speaking for women and their interests. We discuss how our analysis of the framing of issues as social problems complements and extends social psychological analyses of activism. © 2018 The British Psychological Society.
Induced abortion in Italy: levels, trends and characteristics.

Bettarini, S S; D'Andrea, S S

1996-01-01

Subsequent to the legalization of abortion in Italy in 1978, abortion; rates among Italian women first rose and then declined steadily, from a peak of 16.9 abortions per 1,000 women of reproductive age in 1983 to 9.8 per 1,000 in 1993. Abortion rates vary considerably by geographic region, with rates typically highest in the more secular and modernized regions and lowest in regions where traditional values predominate. Data from 1981 and 1991 indicate that age-specific abortion rates decreased during the 1980s for all age-groups, with the largest declines occurring in regions with the highest levels of abortion. Moreover, a shift in the age distribution of abortion rates occurred during the 1980s, with women aged 30-34 registering the highest abortion rate in 1991, whereas in 1981 the highest level of abortion occurred among those aged 25-29. The abortion rate among adolescent women was low at both times (7.6 per 1,000 in 1981 and 4.6 per 1,000 in 1991). These data are based only on reported legal abortions; the number of clandestine abortions remains unknown.

To conduct a retrospective observational cohort study to estimate the abortion complication rate, including those diagnosed or treated at emergency departments (EDs). Using 2009-2010 abortion data among women covered by the fee-for-service California Medicaid program and all subsequent health care for 6 weeks after having an abortion, we analyzed reasons for ED visits and estimated the abortion-related complication rate and the adjusted relative risk. Complications were defined as receiving an abortion-related diagnosis or treatment at any source of care within 6 weeks after an abortion. Major complications were defined as requiring hospital admission, surgery, or blood transfusion. A total of 54,911 abortions among 50,273 fee-for-service Medi-Cal beneficiaries were identified. Among all abortions, 1 of 16 (6.4%, n=3,531) was followed by an ED visit within 6 weeks but only 1 of 115 (0.87%, n=478) resulted in an ED visit for an abortion-related complication. Approximately 1 of 5,491 (0.03%, n=15) involved ambulance transfers to EDs on the day of the abortion. The major complication rate was 0.23% (n=126, 1/436): 0.31% (n=35) for medication abortion, 0.16% (n=57) for first-trimester aspiration abortion, and 0.41% (n=34) for second-trimester or later procedures. The total abortion-related complication rate including all sources of care including EDs and the original abortion facility was 2.1% (n=1,156): 5.2% (n=588) for medication abortion, 1.3% (n=438) for first-trimester aspiration abortion, and 1.5% (n=130) for second-trimester or later procedures. Abortion complication rates are comparable to previously published rates even when ED visits are included and there is no loss to follow-up. II.
Decriminalization of abortion in Mexico City: the effects on women's reproductive rights.

PubMed

Becker, Davida; Díaz Olavarrieta, Claudia

2013-04-01

In April 2007, the Mexico City, Mexico, legislature passed landmark legislation decriminalizing elective abortion in the first 12 weeks of pregnancy. In Mexico City, safe abortion services are now available to women through the Mexico City Ministry of Health's free public sector legal abortion program and in the private sector, and more than 89 000 legal abortions have been performed. By contrast, abortion has continued to be restricted across the Mexican states (each state makes its own abortion laws), and there has been an antichoice backlash against the legislation in 16 states. Mexico City's abortion legislation is an important first step in improving reproductive rights, but unsafe abortions will only be eliminated if similar abortion legislation is adopted across the entire country.
Earth reencounter probabilities for aborted space disposal of hazardous nuclear waste

1977-01-01

A quantitative assessment is made of the long-term risk of earth reencounter and reentry associated with aborted disposal of hazardous material in the space environment. Numerical results are presented for 10 candidate disposal options covering a broad spectrum of disposal destinations and deployment propulsion systems. Based on representative models of system failure, the probability that a single payload will return and collide with earth within a period of 250,000 years is found to lie in the range .0002-.006. Proportionately smaller risk attaches to shorter time intervals. Risk-critical factors related to trajectory geometry and system reliability are identified as possible mechanisms of hazard reduction.
Effect of mifepristone on abortion access in the United States.

PubMed

Finer, Lawrence B; Wei, Junhow

2009-09-01

To examine the pattern of mifepristone uptake in the United States and whether the introduction of this drug has facilitated access to abortion services. Using data from a national census of abortion providers and from the U.S. distributor of mifepristone, we assessed the number and proportion of abortions performed using mifepristone, the distribution of mifepristone providers by provider type and medical specialty, and the geographic distribution of mifepristone and surgical providers. The number of mifepristone providers increased from 208 in the last 2 months of 2000 to 700 in 2001, the first full year of availability, and to 902 in 2007. Some 158,000 mifepristone abortions were performed in 2007, representing an estimated 14% of all abortions and 21% of eligible early abortions. Physicians represented 51% of mifepristone providers but accounted for just 11% of abortions; most were obstetrician-gynecologists. The proportion of abortions in each state performed using mifepristone ranged from 0% to 80%. Most mifepristone abortions were performed at or near facilities that also provided surgical abortion. Only five mifepristone-only providers of 10 or more abortions were located farther than 50 miles from any surgical provider of 400 or more abortions. Mifepristone has become an integral part of abortion provision in the United States and likely has contributed to a trend toward very early abortions. However, expectations that approval of mifepristone would result in a wider range of providers offering abortion have not yet been met, and mifepristone has not brought a major improvement in the geographic availability of abortion.

Medical abortion was introduced in Nepal in 2009, but rural women's access to medical abortion services remained limited. We conducted a district-level operations research study to assess the effectiveness of training 13 auxiliary nurse-midwives as medical abortion providers, and 120 female community health volunteers as communicators and referral agents for expanding access to medical abortion for rural women. Interviews with service providers and women who received medical abortion were undertaken and service statistics were analysed. Compared to a neighbouring district with no intervention, there was a significant increase in the intervention area in community health volunteers' knowledge of the legal conditions for abortion, the advantages and disadvantages of medical abortion, safe places for an abortion, medical abortion drugs, correct gestational age for home use of medical abortion, and carrying out a urine pregnancy test. In a one-year period in 2011-12, the community health volunteers did pregnancy tests for 584 women and referred 114 women to the auxiliary nurse-midwives for abortion; 307 women in the intervention area received medical abortion services from auxiliary nurse-midwives. There were no complications that required referral to a higher-level facility except for one incomplete abortion. Almost all women who opted for medical abortion were happy with the services provided. The study demonstrated that auxiliary nurse-midwives can independently and confidently provide medical abortion safely and effectively at the sub-health post level, and community health volunteers are effective change agents in informing women about medical abortion.

Anti-legal attitude toward abortion among abortion patients in the United States.

Thomas, Rachel G; Norris, Alison H; Gallo, Maria F

2017-11-01

To measure the prevalence of believing that abortion should be illegal in all or most cases among women obtaining an abortion in the United States and to identify correlates of holding this belief. Study population was drawn from the nationally-representative 2008 Abortion Patient Survey. The primary outcome was having an anti-legal abortion attitude, defined as agreeing that abortion should be illegal in all or most cases. We assessed potential correlates in bivariable and multivariable analyses using weights to account for the complex sampling. A total of 4769 abortion patients completed the survey module containing the question on abortion legality, of which 4492 (94.2%) had non-missing data for the outcome. Overall, 4.1% of patients (N=183) reported an anti-legal abortion attitude. Correlates of having anti-legal attitude included being married, at <200% federal poverty level, fundamentalist, contraception non-use, no abortion history, perceiving the pregnancy with ambivalence or as unintended, and using misoprostol or another product on their own to bring back their period or end the pregnancy. Abortion patients who do not believe abortion should be legal appear to differ substantially from women who are more supportive of legality. Findings raise important questions about this subset of patients, including whether possible discordance between patient beliefs and behavior could influence their use of medical abortion or other products. Some abortion patients do not agree with abortion legality, and this subset could experience a degree of cognitive dissonance, which could influence the method by which they seek to abort.

Factors associated with repeat induced abortion in Kenya.

Maina, Beatrice W; Mutua, Michael M; Sidze, Estelle M

2015-10-12

Over six million induced abortions were reported in Africa in 2008 with over two million induced abortions occurring in Eastern Africa. Although a significant proportion of women in the region procure more than one abortion during their reproductive period, there is a dearth of research on factors associated with repeat abortion. Data for this study come from the Magnitude and Incidence of Unsafe Abortion Study conducted by the African Population and Health Research Center in Kenya in 2012. The study used a nationally-representative sample of 350 facilities (level II to level VI) that offer post-abortion services for complications following induced and spontaneous abortions. A prospective morbidity survey tool was used by health providers in 328 facilities to collect information on socio-demographic charateristics, reproductive health history and contraceptive use at conception for all patients presenting for post-abortion services. Our analysis is based on data recorded on 769 women who were classified as having had an induced abortion. About 16 % of women seeking post abortion services for an induced abortion reported to have had a previous induced abortion. Being separated or divorced or widowed, having no education, having unwanted pregnancy, having 1-2 prior births and using traditional methods of contraception were associated with a higher likelihood of a repeat induced abortion. The findings point to the need to address the reasons why women with first time induced abortion do not have the necessary information to prevent unintended pregnancies and further induced abortions. Possible explanations linked to the quality of post-abortion family planning and coverage of long-acting methods should be explored.

Background Tanzania has one of the highest maternal mortality ratios in the world, and unsafe abortion is one of its leading causes. Yet little is known about its incidence. Objectives To provide the first ever estimates of the incidence of unsafe abortion in Tanzania, at the national level and for each of the 8 geopolitical zones (7 in Mainland plus Zanzibar). Methods A nationally representative survey of health facilities was conducted to determine the number of induced abortion complications treated in facilities. A survey of experts on abortion was conducted to estimate the likelihood of women experiencing complications and obtaining treatment. These surveys were complemented with population and fertility data to obtain abortion numbers, rates and ratios, using the Abortion Incidence Complications Methodology. Results In Tanzania, women obtained just over 405,000 induced abortions in 2013, for a national rate of 36 abortions per 1,000 women age 15–49 and a ratio of 21 abortions per 100 live births. For each woman treated in a facility for induced abortion complications, 6 times as many women had an abortion but did not receive care. Abortion rates vary widely by zone, from 10.7 in Zanzibar to 50.7 in the Lake zone. Conclusions The abortion rate is similar to that of other countries in the region. Variations by zone are explained mainly by differences in fertility and contraceptive prevalence. Measures to reduce the incidence of unsafe abortion and associated maternal mortality include expanding access to post-abortion care and contraceptive services to prevent unintended pregnancies.

1992-01-01

This article grew out of a keynote address prepared for the conference, "From Abortion to Contraception: Public Health Approaches to Reducing Unwanted Pregnancy and Abortion Through Improved Family Planning Services," held in Tbilisi, Georgia, USSR in October 1990. The article reviews the legal, religious, and medical situation of induced abortion in Europe in historical perspective, and considers access to abortion services, attitudes of health professionals, abortion incidence, morbidity and mortality, the new antiprogestins, the characteristics of abortion seekers, late abortions, postabortion psychological reactions, effects of denied abortion, and repeat abortion. Special attention is focused on the changes occurring in Romania, Albania, and the former Soviet Union, plus the effects of the new conservatism elsewhere in the formerly socialist countries of central and eastern Europe, particularly Poland. Abortion is a social reality that can no more be legislated out of existence than the controversy surrounding it can be stilled. No matter how effective family planning services and practices become, there will always be a need for access to safe abortion services.
Effects of Legislation Regulating Abortion in Arizona.

Abortion is a common and safe procedure in the United States, the regulation of which varies by state. Since 2011, hundreds of state-level abortion restrictions have been enacted by legislatures across the country. This study describes the effects of two such regulations enacted in 2011 in Arizona, (A.R.S.) 36-2153 and 36-2155, that imposed a 24-hour waiting period requiring two separate in-person clinic visits before obtaining an abortion and banned advanced practice clinicians such as physician assistants, nurse practitioners, and nurse midwives from inducing medication abortions by prescribing mifepristone. We conducted a pre-post study to describe the effect of Arizona's scope of practice law on abortion provision by county. Using publicly available data, we compared patterns of abortion provision in 2009 and 2010 (before the laws) with 2012 and 2013. Our primary objective was to compare the proportion of abortions performed with medication by prescription of mifepristone (versus abortions performed surgically, known as aspiration abortions) before and after the laws were enacted. Our secondary objectives were to report the number of counties that lost an abortion provider and the change in the proportion of abortions performed before 14 weeks' gestation of pregnancy after the enactment of the laws. After enactment of the laws, the proportion of Arizona's 15 counties with abortion clinics decreased from 33% to 13%. Over this time, the proportion of abortions performed with medication in Arizona decreased by 17.4% (95% CI, 16.6%-18.3%; p = .0002), from 47.6% to 30.2%. Similarly, the proportion of abortions performed before 14 weeks' gestation in Arizona decreased by 3.3% (95% CI, 2.8%-3.8%; p = .0002) after the enactment of these laws. The proportion of abortions performed with medication and the proportion of abortion performed before 14 weeks' gestation in Arizona were negatively affected by the enactment of these laws. These findings are not explained by national temporal trends in abortion, because the proportion of abortions performed with medication increased and early abortions remained stable over the same time period in the United States as a whole. Proponents of laws restricting the provision of abortion such as these claim to improve the safety of abortion, but they actually seem to decrease access to abortion, as defined by the number of counties with abortion providers, and subsequently lead to delays in abortion. These data should inform future policies by providing an example of how such laws affect women seeking abortion. Copyright © 2018 Jacobs Institute of Women's Health. Published by Elsevier Inc.

Unsafe abortion is a leading cause of death among young women aged 10-24 years in sub-Saharan Africa. Although having multiple induced abortions may exacerbate the risk for poor health outcomes, there has been minimal research on young women in this region who have multiple induced abortions. The objective of this study was therefore to assess the prevalence and correlates of reporting a previous induced abortion among young females aged 12-24 years seeking abortion-related care in Kenya. We used data on 1,378 young women aged 12-24 years who presented for abortion-related care in 246 health facilities in a nationwide survey conducted in 2012. Socio-demographic characteristics, reproductive and clinical histories, and physical examination assessment data were collected from women during a one-month data collection period using an abortion case capture form. Nine percent (n = 98) of young women reported a previous induced abortion prior to the index pregnancy for which they were receiving care. Statistically significant differences by previous history of induced abortion were observed for area of residence, religion and occupation at bivariate level. Urban dwellers and unemployed/other young women were more likely to report a previous induced abortion. A greater proportion of young women reporting a previous induced abortion stated that they were using a contraceptive method at the time of the index pregnancy (47 %) compared with those reporting no previous induced abortion (23 %). Not surprisingly, a greater proportion of young women reporting a previous induced abortion (82 %) reported their index pregnancy as unintended (not wanted at all or mistimed) compared with women reporting no previous induced abortion (64 %). Our study results show that about one in every ten young women seeking abortion-related care in Kenya reports a previous induced abortion. Comprehensive post-abortion care services targeting young women are needed. In particular, post-abortion care service providers must ensure that young clients receive contraceptive counseling and effective pregnancy prevention methods before discharge from the health care facility to prevent unintended pregnancies that may result in subsequent induced abortions.

Background The Medical Termination of Pregnancy (MTP) Act of 1971 liberalized abortion laws in India. This study examines changes in abortion service provision and characteristics of abortion providers in Bihar and Jharkhand states, India between 2004 and 2013. Methods We used state-representative data from cross-sectional surveys of reproductive health service providers we conducted in 2004 (N = 1,323) and 2012/2013 (N = 1,020). We employed chi-squared tests to examine and compare abortion providers’ characteristics, and fitted separate multivariate logistic regression models for provision of surgical, medical, and any abortion services, respectively, adjusting for potential confounders to identify factors associated with abortion service provision at the two survey time points. Results Of providers interviewed in 2004 and 2012/2013, 63.7% and 84.5%, respectively, offered abortion services. Among abortion providers, 21.1% offered surgical and 10.7% offered medical abortions in 2004; 15.8% and 94.1% did so, respectively, in 2012/2013. Private providers were more likely than public providers to offer abortion services at both time points. Compared to female providers, male providers were significantly less likely to provide both surgical and medical abortions in 2004, and significantly less likely to provide surgical abortions in 2012/2013. Pharmacists and community health workers played increasingly important roles in abortion service provision, especially medical abortion, during the period. Conclusion This study documents important changes in abortion provision in the two Indian states during 2004–2013. PMID:29879132
The role of oxidative stress in spontaneous abortion and recurrent pregnancy loss: a systematic review.

2007-05-01

Human reproduction is not considered a highly efficient biological process. Before the end of the first trimester, 30%-50% of conceptions end in spontaneous abortion. Most losses occur at the time of implantation. 15%-20% of clinical pregnancies end in spontaneous abortions. Recurrent pregnancy loss is a frustrating clinical problem both for clinicians and patients. Recurrent pregnancy loss affects 0.5%-3% of women in the reproductive age group, and between 50%-60% of recurrent pregnancy losses are idiopathic. Oxidative stress-induced damage has been hypothesized to play a role in spontaneous abortion, idiopathic recurrent pregnancy loss, hydatidiform mole, defective embryogenesis, and drug-induced teratogenicity. Some studies implicate systemic and placental oxidative stress in the pathophysiology of abortion and recurrent pregnancy loss. Oxidant-induced endothelial damage, impaired placental vascularization and immune malfunction have all been proposed to play a role in the pathophysiology of idiopathic recurrent pregnancy loss. Oxidative stress-induced placental dysfunction may be a common cause of the multifactorial and polygenic etiologies of abortion, recurrent pregnancy loss, defective embryogenesis, hydatidiform mole, and drug-induced teratogenic effects. Oxidative stress-induced modification of phospholipids has been linked to the formation of antiphospholipid antibodies in the antiphospholipid syndrome. The objective of this review was to examine the association between oxidative stress, spontaneous abortion and recurrent pregnancy loss, based on the published literature. We conducted an extensive literature search utilizing the databases of Medline, CINAHL, and Cochrane from 1986 to 2005. The following keywords were used: oxidative stress, abortion, recurrent pregnancy loss, reactive oxygen species, antioxidants, fetal development, and embryopathies. We conducted an electronic search, as well as a manual search of cross-references. We have included all studies in the English language found in the literature focusing on oxidative stress and its association with abortions, recurrent pregnancy loss and drug-induced teratogenicity. The role of antioxidant vitamins for primary prevention of oxidative stress-induced pathologies needs to be investigated further. Obstetricians & Gynecologists, Family Physicians. After completion of this article, the reader should be able to state that the causes of spontaneous and recurrent abortion are multifaceted, however, some of the causes may be preventable and also explain that the role of oxidative stress during pregnancy and adverse pregnancy outcomes has a basis in pathophysiology, although the role of oxidative stress and the treatment of oxidative stress during or before pregnancy remains speculative.

Due to increasing usage of chemicals in various industries, occupational exposure of women with these materials is unavoidable. Nowadays, some studies indicate adverse effects of exposure to these chemicals, especially organic solvents on the reproductive system of females. This study aimed to assess the relationship between spontaneous abortion and occupational exposure to organic solvents mixture in pharmaceutical industry. This study was carried out in a pharmaceutical factory located in the suburb of Tehran in 2010. During the study, married women who were working in the factory laboratory units and had exposure to mixed organic solvents were compared with married women who were working in the packing units of the factory without occupational exposure to organic solvents in terms of spontaneous abortion frequency and duration of pregnancy using statistical methods. In this study, the frequency of spontaneous abortion in employees with and without exposure to organic solvents mixture was 10.7 and 2.9% respectively. This study showed that even after adjustment for confounding factors, there was a significant correlation between spontaneous abortion and occupational exposure to organic solvents mixture and this correlation increased with increasing levels of exposure to organic solvents. Also, a significant correlation was observed between occupational exposure to mixed organic solvents and waiting time to become pregnant (TTP). Furthermore, this study showed that even after adjustment for confounding variables, shift workers were significantly more affected by spontaneous abortion compared to daytime workers (P < 0.001). Also, in our study, synergistic effect between shift working and occupational exposure to organic solvents mixture on spontaneous abortion was seen. According to the results of this study, since there is probability of spontaneous abortion resulting from occupational exposure to various chemicals including organic solvents, recommendation to review the status of occupational exposure of workers can be helpful in improving fertility consultations and reproductive health.

To describe the social characteristics of women seeking a medical abortion, and the conditions of that abortion, according to whether they had one or more previous induced abortions. An observational study was carried out in 11 French units in 2013-2014, among women 18 years or older. A self-administered questionnaire on the abortion context and social situation was given to them, as well as a diary to record the pain level for each of five days following the mifepristone intake. The sample included 453 women. Among the respondents, 22% had had one previous abortion and 8% had had two or more. Women having had a previous voluntary abortion were more often isolated and in a poorer social situation than women having their first abortion. Better support for contraception after abortion could reduce the number of repeated abortions. Copyright © 2017 Elsevier Masson SAS. All rights reserved.
Medical abortion reversal: science and politics meet.

2018-03-01

Medical abortion is a safe, effective, and acceptable option for patients seeking an early nonsurgical abortion. In 2014, medical abortion accounted for nearly one third (31%) of all abortions performed in the United States. State-level attempts to restrict reproductive and sexual health have recently included bills that require physicians to inform women that a medical abortion is reversible. In this commentary, we will review the history, current evidence-based regimen, and regulation of medical abortion. We will then examine current proposed and existing abortion reversal legislation. The objective of this commentary is to ensure physicians are armed with rigorous evidence to inform patients, communities, and policy makers about the safety of medical abortion. Furthermore, given the current paucity of evidence for medical abortion reversal, physicians and policy makers can dispel bad science and misinformation and advocate against medical abortion reversal legislation.

2009-01-01

Unsafe abortion remains a huge problem in Nepal even after legalization of abortion. Various myths and misconceptions persist which prompt women towards unsafe abortive practices. A qualitative study was conducted among different groups of women using focus group discussions and in depth interviews. Perception and understanding of the participants on abortion, methods and place of abortion were evaluated. A number of misconceptions were prevalent like drinking vegetable and herbal juices, and applying hot pot over the abdomen could abort pregnancy. However, many participants also believed that health care providers should be consulted for abortion. Although majority of the women knew that they should seek medical aid for abortion, they were still possessed with various misconceptions. Merely legalizing abortion services is not enough to reduce the burden of unsafe abortion. Focus has to be given on creating awareness and proper advocacy in this issue.
Situating stigma in stratified reproduction: Abortion stigma and miscarriage stigma as barriers to reproductive healthcare.

To examine whether race and reported history of abortion are associated with abortion stigma and miscarriage stigma, both independently and comparatively. Self-administered surveys with 306 new mothers in Boston and Cincinnati, United States. Abortion stigma perception (ASP); miscarriage stigma perception (MSP); and comparative stigma perception (CSP: abortion stigma perception net of miscarriage stigma perception). Regardless of whether or not they reported having an abortion, white women perceived abortion (ASP) to be more stigmatizing than Black and Latina women. Perceptions of miscarriage stigma (MSP), on the other hand, were dependent on reporting an abortion. Among those who reported an abortion, Black women perceived more stigma from miscarriage than white women, but these responses were flipped for women who did not report abortion. Reporting abortion also influenced our comparative measure (CSP). Among those who did report an abortion, white women perceived more stigma from abortion than miscarriage, while Black and Latina women perceived more stigma from miscarriage than abortion. By measuring abortion stigma in comparison to miscarriage stigma, we can reach a more nuanced understanding of how perceptions of reproductive stigmas are stratified by race and reported reproductive history. Clinicians should be aware that reproductive stigmas do not similarly affect all groups. Stigma from specific reproductive outcomes is more or less salient dependent upon a woman's social position and lived experience. Copyright © 2016 Elsevier B.V. All rights reserved.

We sought to examine knowledge, attitudes and practices regarding legal abortion among a group of Peruvian physicians. A pre-conference survey was mailed to Peruvian physicians invited to a workshop on legal abortion. A post-conference survey was distributed following the event. Eighty-six percent of 35 respondents correctly indicated that abortion is legal in Peru when a pregnancy endangers a woman's life while less than 50% knew it is also legal when necessary to protect a woman's health. Knowledge about abortion techniques was lower for induced abortion than for management of incomplete abortions. Dilation and curettage was used more frequently than manual vacuum aspiration and medications. Half of physicians reported having performed a legal abortion. The vast majority of physicians surveyed thought legal indications for abortion should be expanded to include cases of rape or fetal malformations. Most considered their abortion training to be inadequate. They identified lack of training and administrative and professional support as barriers to legal abortion provision. Physicians surveyed were willing to provide legal abortions but lacked the knowledge, skills, and support to do so. Improved training of health professionals, increasing institutional support, and developing administrative and legal procedures to guide management of women seeking abortions could increase women's access to legal abortion services and diminish the occurrence of unsafe abortion in Peru.
The political economy of abortion in India: cost and expenditure patterns.

Duggal, Ravi

2004-11-01

Access to abortion services is not difficult in India, even in remote areas. Providers of abortion range from traditional birth attendants to auxiliary nurse midwives and pharmacists, unqualified and qualified private doctors, to gynaecologists. Despite a well-defined law, there is a lack of regulation of abortion services or providers, and the cost to women is determined by supply side economics. The state is not a leading provider of abortions; services remain predominantly in the private sector. Abortions in the public sector are free only if the woman accepts some form of contraception; other fees may also be charged. The cost of abortion varies considerably, depending on the number of weeks of pregnancy, the woman's marital status, the method used, type of anaesthesia, whether it is a sex-selective abortion, whether diagnostic tests are carried out, whether the provider is registered and whether hospitalisation is required. A review of existing studies indicates that abortions cost a substantial amount--first trimester abortion averages Rs.500- 1000 and second trimester abortion Rs.2000-3000. Given the number of unqualified providers and with 15-20% of maternal deaths due to unsafe abortions, the costs of unsafe abortions must also be counted. It is imperative for the state to regulate the abortion economy in India, both to rationalise costs and assure safe abortions for women.

Background Abortion is a serious public health issue, and it poses high risks to the health and life of women. Yet safe abortion services are not readily available because few doctors are trained to provide such services. Many doctors are unaware of laws pertaining to abortion. This article reports survey findings on Malaysian medical students’ attitudes toward abortion education and presents a case for including abortion education in medical schools. Methods and Results A survey on knowledge of and attitudes toward abortion among medical students was conducted in two public universities and a private university in Malaysia in 2011. A total of 1,060 students returned the completed questionnaires. The survey covered about 90% of medical students in Years 1, 3, and 5 in the three universities. About 90% of the students wanted more training on the general knowledge and legal aspects of abortion, and pre-and post-abortion counseling. Overall, 75.9% and 81.0% of the students were in favor of including in medical education the training on surgical abortion techniques and medical abortion, respectively. Only 2.4% and 1.7% were opposed to the inclusion of training of these two methods in the curriculum. The remaining respondents were neutral in their stand. Desire for more abortion education was associated with students’ pro-choice index, their intention to provide abortion services in future practice, and year of study. However, students’ attitudes toward abortion were not significantly associated with gender, type of university, or ethnicity. Conclusions Most students wanted more training on abortion. Some students also expressed their intention to provide abortion counseling and services in their future practice. Their desire for more training on abortion should be taken into account in the new curriculum. Abortion education is an important step towards making available safe abortion services to enable women to exercise their reproductive rights. PMID:23300600

To identify and compare the time dynamics of artificial abortions in two (Czech and Slovak) ethnically, historically and socially closely related populations. Data have been taken separately for 12-15 and 16-18 year age girls from official exhaustive statistical sources and processed by advanced procedures of time series analysis. Czech and Slovak Republics. All girls of the given age. Legislative liberalization of abortions 1987. Estimated starting values of relative numbers of abortions by 1971, increasing linear trends, period lengths of fluctuation, coefficients of determination and those of cross-correlation. Level of significance alpha = 0.05. The Czech figures are significantly higher than the Slovak. Thus, estimated abortion percentage (from pregnancies) for 1971 was for younger Czech girls 53%, and for those from Slovakia 29%. All estimated trends were increasing significantly in all cases for the Czech population (by 1.5% per year in the younger group) and in one case for Slovakia. The estimated period lengths were usually 10-12 years. Czech and Slovak data display significant positive mutual cross-correlation, the delay being 1-3 years in Slovak girls. Surprisingly, all data significantly cross-correlate with the geomagnetic index value Ap, acting as lead-lag, with 3-6-year delay for abortions. Despite living in the same federal state--the former Czechoslovak Republic, both Czech and Slovak populations do differ in starting values and general trends of abortions in teenagers. This can be due to historical, racial and religious peculiarities as well as a more advanced process of industrialization in the western part--the Czech Republic. The latter hypothesis is corroborated by strong dynamism of changes and by the time delay in Slovakia. The periodicity exhibits a frequency resembling that known for solar motion round barycenter of solar system, for sunspots and geomagnetism.
Roe v. Wade and the lesson of the pre-Roe case law.

PubMed

Morgan, R G

1979-08-01

The attempt is made in this discussion to demonstrate that the Supreme Court in deciding the Roe v. Wade case should not have decided an abortion case when it did and that the opinion was almost destined to be bad in that the Court could find no persuasive rationale in the pre-Roe cases for each of the points in its decision. In 1973 political forces were actively debating abortion. Abortions had been prohibited by most states, except to save a woman's life, since the 19th century. In the 5 years immediately preceding Roe, 13 states had revised their statutes to resemble the Model Penal Code's provisions, which permitted abortions if the pregnancy threatened the woman's life, if it would gravely impair her physical or mental health, if it resulted from rape or incest, or if the child would be born with grave physical or mental defects. 4 states had removed all restrictions on the permissible reasons for seeking an abortion before a pregnancy passed specified lengths. In short, in many states the political process had yet to decide on abortion, but Roe's rejection of Texas's statute voided almost every other state's statutes as well. Between 1970 and 1972, a flurry of constitutional challenges hit the courts. 3 years was hardly sufficient time for the judicial system to evolve sound analysis for such an emotionally charged issue as abortion. The Court could justifiably have allowed the dispute to simmer longer in the lower courts. There is some indication that a sounder case law might evolved if given time, but that was prevented by Roe. The Court could not find a rationale in 1973, but it decided anyway, suggesting a legislative rather than a judicial process.
Safety of Medical Abortion Provided Through Telemedicine Compared With In Person.

Grossman, Daniel; Grindlay, Kate

2017-10-01

To compare the proportion of medical abortions with a clinically significant adverse event among telemedicine and in-person patients at a clinic system in Iowa during the first 7 years of the service. We conducted a retrospective cohort study. We analyzed data on clinically significant adverse events (hospital admission, surgery, blood transfusion, emergency department treatment, and death) for all medical abortions performed by telemedicine or in person at a clinic system in Iowa between July 1, 2008, and June 30, 2015. Data on adverse events came from required reporting forms submitted to the mifepristone distributor. We calculated the prevalence of adverse events and 95% CIs comparing telemedicine with in-person patients. The analysis was designed as a noninferiority study. Assuming the prevalence of adverse events to be 0.3%, telemedicine provision was considered to be inferior to in-person provision if the prevalence were 0.6% or higher. The required sample size was 6,984 in each group (one-sided α=0.025, power 90%). To explore whether patients with adverse events presented to emergency departments and were not reported, we conducted a survey of the 119 emergency departments in Iowa, asking whether they had treated a woman with an adverse event in the prior year. During the study period, 8,765 telemedicine and 10,405 in-person medical abortions were performed. Forty-nine clinically significant adverse events were reported (no deaths or surgery; 0.18% of telemedicine patients with any adverse event [95% CI 0.11-0.29%] and 0.32% of in-person patients [95% CI 0.23-0.45%]). The difference in adverse event prevalence was 0.13% (95% CI -0.01% to 0.28%, P=.07). Forty-two emergency departments responded to the survey (35% response rate); none reported treating a woman with an adverse event after medical abortion. Adverse events are rare with medical abortion, and telemedicine provision is noninferior to in-person provision with regard to clinically significant adverse events.
Decriminalization of Abortion in Mexico City: The Effects on Women’s Reproductive Rights

PubMed Central

Díaz Olavarrieta, Claudia

2013-01-01

In April 2007, the Mexico City, Mexico, legislature passed landmark legislation decriminalizing elective abortion in the first 12 weeks of pregnancy. In Mexico City, safe abortion services are now available to women through the Mexico City Ministry of Health’s free public sector legal abortion program and in the private sector, and more than 89 000 legal abortions have been performed. By contrast, abortion has continued to be restricted across the Mexican states (each state makes its own abortion laws), and there has been an antichoice backlash against the legislation in 16 states. Mexico City’s abortion legislation is an important first step in improving reproductive rights, but unsafe abortions will only be eliminated if similar abortion legislation is adopted across the entire country.

Provision of safe abortion is widely recognized as vital to addressing the health and wellbeing of populations. Research on abortion is essential to meet the UN Sustainable Development Goals. Researchers in population health from university, policy, and practitioner contexts working on two multidisciplinary projects on family planning and safe abortion in Africa and Asia were brought together for a workshop to discuss the future research agenda on induced abortion. Research on care-seeking behavior, supply of abortion care services, and the global and national policy context will help improve access to and experiences of safe abortion services. A number of areas have potential in designing intervention strategies, including clinical innovations, quality improvement mechanisms, community involvement, and task sharing. Research on specific groups, including adolescents and young people, men, populations affected by conflict, marginalized groups, and providers could increase understanding of provision, access to and experiences of induced abortion. Methodological and conceptual advances, for example in the measurement of induced abortion incidence, complications, and client satisfaction, conceptualizations of induced abortion access and care, and methods for follow-up of patients who have induced abortions, will improve the accuracy of measurements of induced abortion, and add to understanding of women's experiences of induced abortions and abortion care. © 2018 International Federation of Gynecology and Obstetrics.
Late-Term Elective Abortion and Susceptibility to Posttraumatic Stress Symptoms

Coleman, Priscilla K.; Coyle, Catherine T.; Rue, Vincent M.

2010-01-01

The primary aim of this study was to compare the experience of an early abortion (1st trimester) to a late abortion (2nd and 3rd trimester) relative to Posttraumatic Stress Disorder (PTSD) symptoms after controlling for socio-demographic and personal history variables. Online surveys were completed by 374 women who experienced either a 1st trimester abortion (up to 12 weeks gestation) or a 2nd or 3rd trimester abortion (13 weeks gestation or beyond). Most respondents (81%) were U.S. citizens. Later abortions were associated with higher Intrusion subscale scores and with a greater likelihood of reporting disturbing dreams, reliving of the abortion, and trouble falling asleep. Reporting the pregnancy was desired by one's partner, experiencing pressure to abort, having left the partner prior to the abortion, not disclosing the abortion to the partner, and physical health concerns were more common among women who received later abortions. Social reasons for the abortion were linked with significantly higher PTSD total and subscale scores for the full sample. Women who postpone their abortions may need more active professional intervention before securing an abortion based on the increased risks identified herein. More research with diverse samples employing additional measures of mental illness is needed. PMID:21490737

Making abortions safe: a matter of good public health policy and practice.

PubMed Central

Berer, M.

2000-01-01

Globally, abortion mortality accounts for at least 13% of all maternal mortality. Unsafe abortion procedures, untrained abortion providers, restrictive abortion laws and high mortality and morbidity from abortion tend to occur together. Preventing mortality and morbidity from abortion in countries where these remain high is a matter of good public health policy and medical practice, and constitutes an important part of safe motherhood initiatives. This article examines the changes in policy and health service provision required to make abortions safe. It is based on a wide-ranging review of published and unpublished sources. In order to be effective, public health measures must take into account the reasons why women have abortions, the kind of abortion services required and at what stages of pregnancy, the types of abortion service providers needed, and training, cost and counselling issues. The transition from unsafe to safe abortions demands the following: changes at national policy level; abortion training for service providers and the provision of services at the appropriate primary level health service delivery points; and ensuring that women access these services instead of those of untrained providers. Public awareness that abortion services are available is a crucial element of this transition, particularly among adolescent and single women, who tend to have less access to reproductive health services generally.

Abortion clinic patients' opinions about obtaining abortions from general women's health care providers.

Most U.S. women obtain abortions at specialty clinics. This qualitative study explores abortion clinic patients' opinions about receiving abortions from general women's health care providers. We conducted 20 h-long, semi-structured interviews with diverse women who had abortions in the U.S. Heartland. Each described her usual health care provider and how she accessed abortion care. We used qualitative analytic methods to organize and interpret the data. Despite having a general provider, most women sought clinic abortions. Some women offered reasons for preferring specialty care and others for preferring abortion from their general provider. Most women assumed their general provider did not "do abortion" and many believed those providers were opposed to abortion. Women who had delivered a baby were concerned with their image in their general provider's eyes. Two women were denied care by their general providers. Women's preferences for abortion care centered on privacy, cost, empathy, ability to control their image, and desire for safe quality care. Two women who sought abortions through their general providers experienced negative repercussions. General providers should proactively make patients aware of their positions on abortion and if supportive indicate that they can provide that care and/or a referral.

Can stories reduce abortion stigma? Findings from a longitudinal cohort study.

PubMed

Cockrill, Kate; Biggs, Antonia

2018-03-01

Women often hide or selectively disclose abortion experiences due to stigma. Secrecy can help women avoid stigma but may also result in isolation and a lack of social support and contribute to broader social silence. This study assesses whether a book-club intervention can support abortion disclosure among book club participants and improve participants' affective responses towards women who have abortions and abortion providers. A total of 109 women from 13 all-female book clubs located in 9 US states read and discussed a non-fiction book that included stories about pregnancy and abortion, participated in a book club discussion and completed baseline, immediate post-intervention and endline surveys. In 10 out of the 13 book club discussions, at least one member disclosed having had a previous abortion. Overall, 15 of the 19 women who privately reported having a previous abortion self-disclosed one or more abortions during the book club discussion. Following the book club intervention, women reported having more positive feelings toward women who have abortions and abortion providers. Greater improvement and longer lasting effects were seen in groups where there was also an in-person disclosure of abortion experience. Findings suggest that exposure to the stories of women who have had abortions can reduce abortion stigma.

Patient Information Websites About Medically Induced Second-Trimester Abortions: A Descriptive Study of Quality, Suitability, and Issues.

PubMed

Carlsson, Tommy; Axelsson, Ove

2017-01-10

Patients undergoing medically induced second-trimester abortions feel insufficiently informed and use the Web for supplemental information. However, it is still unclear how people who have experience with pregnancy termination appraise the quality of patient information websites about medically induced second-trimester abortions, whether they consider the websites suitable for patients, and what issues they experience with the websites. Our objective was to investigate the quality of, suitability of, and issues with patient information websites about medically induced second-trimester abortions and potential differences between websites affiliated with the health care system and private organizations. We set out to answer the objective by using 4 laypeople who had experience with pregnancy termination as quality assessors. The first 50 hits of 26 systematic searches were screened (N=1300 hits) using search terms reported by the assessors. Of these hits, 48% (628/1300) were irrelevant and 51% (667/1300) led to websites about medically induced second-trimester abortions. After correcting for duplicate hits, 42 patient information websites were included, 18 of which were affiliated with the health care system and 24 with private organizations. The 4 assessors systematically assessed the websites with the DISCERN instrument (total score range 16-80), the Ensuring Quality Information for Patients (EQIP) tool (total score range 0-100), as well as questions concerning website suitability and perceived issues. The interrater reliability was 0.8 for DISCERN and EQIP, indicating substantial agreement between the assessors. The total mean score was 36 for DISCERN and 40 for EQIP, indicating poor overall quality. Websites from the health care system had greater total EQIP (45 vs 37, P>.05) and reliability scores (22 vs 20, P>.05). Only 1 website was recommended by all assessors and 57% (24/42) were rated as very unsuitable by at least one assessor. The most reported issues with the websites involved lack of information (76%, 32/42), and poor design (36%, 15/42). The high number of irrelevant hits and poor quality of patient information websites are considerable issues that must be addressed and considered when consulting patients awaiting medically induced second-trimester abortions. In clinical encounters, health professionals should initiate discussions concerning websites about medically induced second-trimester abortions and inform patients about the issues and quality deficits associated with these websites. ©Tommy Carlsson, Ove Axelsson.

2016-03-01

To assess the association of clinician referral with decision-to-abortion time. We conducted a cross-sectional survey of women seeking abortion at all three Nebraska abortion clinics. We defined referral as direct (information for an abortion clinic), inappropriate (information for a clinic that does not provide abortions) or no referral. Women reported when they recognized their pregnancy, decided to seek abortion and contacted a clinician. The primary outcome - decision-to-abortion time - was time from certain decision to abortion. We used multivariate linear regression analysis, controlling for potential confounders. Participants (n=356) were a mean of 26.8±5.3years old, primarily white (62%), unmarried (88%) and urban (87%), with a mean gestational duration of 8(2/7)weeks (S.D.±20days). Forty-six percent (164) had contacted a clinician and 30% (104) had discussed abortion with one before their abortion. Of those, 30% received a direct referral, 6% received an inappropriate referral and 64% received no referral. Decision-to-abortion time did not vary by referral type [mean difference compared with direct referral: inappropriate referral, 1.1days, 95% confidence interval (CI) -13.4 to 15.6, p=.88; no referral, -0.4days, 95% CI -7.0 to 6.3]. The most common reasons cited for delay in obtaining an abortion were an inability to get an earlier appointment (105/263, 40%) and time needed to raise money to pay for the abortion (73/263, 28%). While neither occurrence of referral nor type was associated with decision-to-abortion times, women in Nebraska continue to face barriers to timely abortion care. Additional research is needed to explore whether quality clinician referral improves abortion access and whether increased resources should be dedicated to improving referral patterns.

Later abortions and mental health: psychological experiences of women having later abortions--a critical review of research.

PubMed

Steinberg, Julia R

2011-01-01

Some abortion policies in the U.S. are based on the notion that abortion harms women's mental health. The American Psychological Association (APA) Task Force on Abortion and Mental Health concluded that first-trimester abortions do not harm women's mental health. However, the APA task force does not make conclusions regarding later abortions (second trimester or beyond) and mental health. This paper critically evaluates studies on later abortion and mental health in order to inform both policy and practice. Using guidelines outlined by Steinberg and Russo (2009), post 1989 quantitative studies on later abortion and mental health were evaluated on the following qualities: 1) composition of comparison groups, 2) how prior mental health was assessed, and 3) whether common risk factors were controlled for in analyses if a significant relationship between abortion and mental health was found. Studies were evaluated with respect to the claim that later abortions harm women's mental health. Eleven quantitative studies that compared the mental health of women having later abortions (for reasons of fetal anomaly) with other groups were evaluated. Findings differed depending on the comparison group. No studies considered the role of prepregnancy mental health, and one study considered whether factors common among women having later abortions and mental health problems drove the association between later abortion and mental health. Policies based on the notion that later abortions (because of fetal anomaly) harm women's mental health are unwarranted. Because research suggests that most women who have later abortions do so for reasons other than fetal anomaly, future investigations should examine women's psychological experiences around later abortions.

Abortion surveillance--United States, 1991.

Koonin, L M; Smith, J C; Ramick, M

1995-05-05

From 1980 through 1991, the number of legal induced abortions reported to CDC remained stable, varying each year by < or = 5%. This report summarizes and reviews information reported to CDC regarding legal induced abortions obtained in the United States during 1991. For each year since 1969, CDC has compiled abortion data received from 52 reporting areas: 50 states, the District of Columbia, and New York City. In 1991, 1,388,937 abortions were reported--a 2.8% decrease from 1990. The abortion ratio was 339 legal induced abortions per 1,000 live births, and the abortion rate was 24 per 1,000 women 15-44 years of age. Women who were undergoing an abortion were more likely to be young, white, and unmarried; most had had no previous live births and had been obtaining an abortion for the first time. More than half (52%) of all abortions were performed at or before the 8th week of gestation, and 88% were before the 13th week. Younger women (i.e., women < 19 years of age) were more likely to obtain abortions later in pregnancy than were older women. Since 1980, the number and rate of abortions have remained relatively stable, with only small year-to-year fluctuations of < or = 5%. However, since 1987, the abortion-to-live-birth ratio has declined; in 1991, the abortion ratio was the lowest recorded since 1977. An increasing rate of childbearing may partially account for this decline. An accurate assessment of the number and characteristics of women who obtain abortions in the United States is necessary both to monitor efforts to prevent unintended pregnancy and to identify and reduce preventable causes of morbidity and mortality associated with abortions.

Teenage abortions predispose women to adverse pregnancy outcomes in subsequent pregnancies such as anemia, stillbirths, preterm deliveries and low birth weight babies. We aim to profile the women presenting for abortions in our institution and determine risk factors for late presentation for abortions. In this retrospective cohort study, all women who underwent an abortion at the National University Hospital, Singapore, from 2005 to 2009 were recruited. Data was obtained from a prepared questionnaire during the mandatory pre-abortion counseling sessions. Profiles of women aged <20 years were compared with those ≥ 20 years old using Chi-square test if the assumptions for Chi-square test were met; otherwise, Fisher's exact test was carried out. Logistic regression was used to investigate the risk factors for second trimester termination of pregnancy. 2109 women presented for induced abortions, of which 1998 had single abortion throughout the course of the study. The mean age of women with single abortion was 29.1 years (sd 7). In the group of women with single abortion, 182 (9.1%) were teenage abortions. In contrast to women ≥ 20 years of age, pregnant teenagers were more likely not to have used any contraception (51.1% vs. 25.2%) and more likely to present late for abortions (39.6% vs. 15.9%). Other risk factors for late presentation for abortions include Malay ethnicity, singlehood, nulliparity and lack of prior usage of contraception. Teenagers are more likely to have no prior contraceptive usage and to present late for abortions. Lack of proper sexual education and awareness of contraceptive measures may have a major contributory factor to such a trend in teenage abortions. Recommendations have been made in order to curb this societal problem. Copyright © 2011 Elsevier Ireland Ltd. All rights reserved.

The Ogive panels will smooth the airflow over the conical spacecraft to limit sound and vibration, which will make for a much smoother ride for the astronauts who will ride inside Orion in the future. The work marked the final major assembly steps for the spacecraft before it is transported to Space Launch Complex 37 at Cape Canaveral Air Force Station in November. Orion is the exploration spacecraft designed to carry astronauts to destinations not yet explored by humans, including an asteroid and Mars. It will have emergency abort capability, sustain the crew during space travel and provide safe re-entry from deep space return velocities.

CSM SCS hardware are highlighted, including translation control, rotation controls, gyro assemblies, a gyro display coupler and flight director attitude indicators. The LM AGS hardware are also highlighted and include the abort electronics assembly and the abort sensor assembly; while the LM CES hardware includes the attitude controller assembly, thrust/translation controller assemblies and the ascent engine arming assemble. Other common hardware including the Orbital Rate Display - Earth and Lunar (ORDEAL) and the Crewman Optical Alignment Sight (COAS), a docking aid, are also highlighted.
Why resort to illegal abortion in Zambia? Findings of a community-based study in Western Province.

PubMed

Koster-Oyekan, W

1998-05-01

This article presents part of the findings of a community-based study on the causes and effects of unplanned pregnancies in four districts of Western Province, Zambia. The study broke the silence around abortion in Western Province and revealed that induced abortion poses a public health problem. Using innovative methodology of recording and analyzing histories of deaths from induced abortion, the abortion mortality ratio was calculated for the study districts. Findings reveal all extremely high induced abortion mortality ratio of 120 induced abortion-related deaths per 100,000 live births. More than half the deaths were of schoolgirls. Although abortion in Zambia is legal on medical and social grounds, most women in Western Province resort to illegal abortions because legal abortion services are inaccessible and unacceptable. The main reasons women resort to abortion is for fear of being expelled from school, their unwillingness to reveal a secret relationship, to protect the health of their previous baby and common knowledge that postpartum sexual taboos have been transgressed. An inventory was made of abortion methods, taboos and abortion-providers. The article describes how health staff were involved throughout the study, and shows how recommendations were made by involving all parties concerned.
Abortion-related maternal mortality in the Russian Federation.

2004-09-01

This study examines characteristics and determinants of maternal mortality associated with induced and spontaneous abortion in the Russian Federation. In addition to national statistical data, the study uses the original medical files of 113 women, representing 74 percent of all women known to have died after undergoing an abortion in 1999. The number of abortions and abortion-related maternal deaths fell fairly steadily during the 1991-2000 decade to levels of 56 percent and 52 percent of the 1991 base, respectively. Regional and urban-rural variation is limited. Nine percent of abortion-related maternal mortality is due to spontaneous abortion; 24 percent is related to induced abortions performed inside and 67 percent to those performed outside a medical institution. In the latter group, older women, usually with a history of several pregnancies, are overrepresented. The high rate of abortion-related maternal mortality is due largely to the number of abortions performed at 13-21 weeks' and 22-27 weeks' gestation both inside and outside medical institutions. Improving access to safe second-trimester abortion, preventing delays during the abortion procedure, and adequate treatment of complications are key strategies for reducing abortion-related maternal mortality.
A review of abortion laws in Western-European countries. A cross-national comparison of legal developments between 1960 and 2010.

PubMed

Levels, Mark; Sluiter, Roderick; Need, Ariana

2014-10-01

The extent to which women have had access to legal abortions has changed dramatically in Western-Europe between 1960 and 2010. In most countries, abortion laws developed from completely banning abortion to allowing its availability on request. Both the timing and the substance of the various legal developments differed dramatically between countries. Existing comparative studies on abortion laws in Western-European countries lack detail, usually focus either on first-trimester abortions or second trimester abortions, cover a limited time-span and are sometimes inconsistent with one another. Combining information from various primary and secondary sources, we show how and when the conditions for legally obtaining abortion during the entire gestation period in 20 major Western-European countries have changed between 1960 and 2010. We also construct a cross-nationally comparable classification of procedural barriers that limit abortion access. Our cross-national comparison shows that Western-Europe witnessed a general trend towards decreased restrictiveness of abortion laws. However, legal approaches to regulating abortion are highly different in detail. Abortion access remains limited, sometimes even in countries where abortion is legally available without restrictions relating to reasons. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.
Update on abortion policy.

To review the status of antiabortion restrictions enacted over the last 5 years in the United States and their impact on abortion services. In recent years, there has been an alarming rise in the number of antiabortion laws enacted across the United States. In total, various states in the union enacted 334 abortion restrictions from 2011 to July 2016, accounting for 30% of all abortion restrictions since the legalization of abortion in 1973. Data confirm, however, that more liberal abortion laws do not increase the number of abortions, but instead greatly decrease the number of abortion-related deaths. Several countries including Romania, South Africa and Nepal have seen dramatic decreases in maternal mortality after liberalization of abortion laws, without an increase in the total number of abortions. In the United States, abortions are incredibly safe with very low rates of complications and a mortality rate of 0.7 per 100 000 women. With increasing abortion restrictions, maternal mortality in the United States can be expected to rise over the coming years, as has been observed in Texas recently. Liberalization of abortion laws saves women's lives. The rising number of antiabortion restrictions will ultimately harm women and their families.

Examine the feasibility of introducing mifepristone-misoprostol medication abortion into existing public sector surgical abortion services in KwaZulu-Natal, South Africa. Cohort study of women offered medication or surgical abortion in a larger medication abortion introduction study. The sample included 1167 women seeking first-trimester abortion at four public sector facilities; 923 women at ≤9 weeks' gestation were eligible for medication abortion. Women who chose medication abortion took 200 mg of mifepristone orally at the facility and 800 mcg of misoprostol buccally (or vaginally if they anticipated or experienced problems with buccal administration) 48 h later at home, based on international research and global safe abortion guidelines. Women who chose surgical abortion received 600 mg of misoprostol sublingually or vaginally on the day of their procedure followed by manual vacuum aspiration 4 h later. Main outcome measures included proportion of eligible women who chose each method, proportion with complete abortion and proportion reporting adverse events. Ninety-four percent of eligible women chose medication abortion. No adverse events were reported by women who chose surgical abortion; 3% of women in the medication abortion group reported adverse events and 0.4% reported a serious adverse event. Seventy-six percent of women received a family planning method at the facility where their received their abortion, with no difference based on procedure type. Medication abortion patients were significantly more likely to report they would choose this method again (94% vs. 78%, p<.001) and recommend the method to a friend (98% vs. 84%, p<.001). Medication abortion was successfully introduced with low and acceptable rates of adverse events; most women at study facilities chose this option. Mifepristone-misoprostol medication abortion was successfully integrated into public sector surgical abortion services in South Africa and was chosen by a large majority of women who were eligible and offered choice of early termination method; access to medication abortion should be expanded in South Africa and other similar settings.

We aimed to assess the effect of an educational intervention on the interest in and support for abortion training among family medicine residents. We conducted a cross-sectional survey before and after an educational lecture on medical and surgical abortion in primary care among 89 residents in 10 New Jersey family medicine programs. Before the lecture, there was more interest in medical abortion training than surgical abortion. Resident interest in surgical abortion and overall support for abortion training increased after the educational intervention (p<.01). Efforts to develop educational programs on early abortion care may facilitate the integration of abortion training in family medicine.

Abortion is highly restricted by law in Senegal. Although women seek care for abortion complications, no national estimate of abortion incidence exists. Data on postabortion care and abortion in Senegal were collected in 2013 using surveys of a nationally representative sample of 168 health facilities that provide postabortion care and of 110 professionals knowledgeable about abortion service provision. Indirect estimation techniques were applied to the data to estimate the incidence of induced abortion in the country. Abortion rates and ratios were calculated for the nation and separately for the Dakar region and the rest of the country. The distribution of pregnancies by planning status and by outcome was estimated. In 2012, an estimated 51,500 induced abortions were performed in Senegal, and 16,700 (32%) resulted in complications that were treated at health facilities. The estimated abortion rate was 17 per 1,000 women aged 15-44 and the abortion ratio was 10 per 100 live births. The rate was higher in Dakar (21 per 1,000) than in the rest of the country (16 per 1,000). Poor women were far more likely to experience abortion complications, and less likely to receive treatment for complications, than nonpoor women. About 31% of pregnancies were unintended, and 24% of unintended pregnancies (8% of all pregnancies) ended in abortion. Unsafe abortion exacts a heavy toll on women in Senegal. Reducing the barriers to effective contraceptive use and ensuring access to postabortion care without the risk of legal consequences may reduce the incidence of and complications from unsafe abortion.

In 2005, Ethiopia's parliament amended the penal code to expand the circumstances in which abortion is legal. Although the country has expanded access to abortion and postabortion care, the last estimates of abortion incidence date from 2008. Data were collected in 2014 from a nationally representative sample of 822 facilities that provide abortion or postabortion care, and from 82 key informants knowledgeable about abortion services in Ethiopia. The Abortion Incidence Complications Methodology and the Prospective Morbidity Methodology were used to estimate the incidence of abortion in Ethiopia and assess trends since 2008. An estimated 620,300 induced abortions were performed in Ethiopia in 2014. The annual abortion rate was 28 per 1,000 women aged 15-49, an increase from 22 per 1,000 in 2008, and was highest in urban regions (Addis Ababa, Dire Dawa and Harari). Between 2008 and 2014, the proportion of abortions occurring in facilities rose from 27% to 53%, and the number of such abortions increased substantially; nonetheless, an estimated 294,100 abortions occurred outside of health facilities in 2014. The number of women receiving treatment for complications from induced abortion nearly doubled between 2008 and 2014, from 52,600 to 103,600. Thirty-eight percent of pregnancies were unintended in 2014, a slight decline from 42% in 2008. Although the increases in the number of women obtaining legal abortions and postabortion care are consistent with improvements in women's access to health care, a substantial number of abortions continue to occur outside of health facilities, a reality that must be addressed.

Access to safe abortion: progress and challenges since the 1994 International Conference on Population and Development (ICPD).

PubMed

Shah, Iqbal H; Åhman, Elisabeth; Ortayli, Nuriye

2014-12-01

The 1994 International Conference on Population and Development (ICPD) viewed access to safe abortion as imperative for public health. Globally, the number of induced abortions (safe and unsafe) per 1000 women aged 15-44 years declined from 35 in 1995 to 28 in 2008. The number of deaths due to unsafe abortion declined from 69,000 in 1990 to 47,000 in 2008, as safe and effective methods of abortion, including manual vacuum aspiration and medical abortion, became more widely available. During the same period, there was a slight increase in the number of countries where abortion is permitted on request, and 70 countries made grounds for abortion more liberal. Since ICPD, the decline in unsafe abortion was slower than that in safe abortion, and unsafe-abortion-related mortality continued to be a problem. Nearly all unsafe abortions and mortality occur in developing countries. While more must be done to ensure universal access to safe, acceptable and affordable contraception to reduce the need for abortion, this need will always exist. Information on grounds for safe abortion should be made widely available for women to access services to which they are legally entitled to. As recommended by ICPD, quality postabortion care including contraception counseling and provision should be available to all women, regardless of the legal grounds for abortion. The paper provides the evidence on unsafe abortion, a reproductive health issue that is entirely preventable but has been largely neglected or tarnished by emotional and contentious debates.

Induced abortion: an overview for internists.

PubMed

Grimes, David A; Creinin, Mitchell D

2004-04-20

Internists care for many women who have had abortions and many who will seek abortions in the future. Each year, about 2% of all women of reproductive age have an abortion. Women having abortions tend to be young, white, unmarried, and early in pregnancy. Most abortions are done by suction curettage under local anesthesia in a freestanding clinic. However, medical abortion is growing in popularity as a nonsurgical alternative. The regimen approved by the U.S. Food and Drug Administration specifies mifepristone, 600 mg orally, followed 2 days later by misoprostol, 400 microg orally (within 49 days from last menses). Recent studies have recommended alternative approaches, such as mifepristone, 200 mg orally, followed in 1 to 3 days by misoprostol, 800 microg vaginally (up to 63 days). Medical abortion can be provided by a broader variety of physicians than can surgical abortion. The overall case-fatality rate for abortion is less than 1 death per 100,000 procedures. Infection, hemorrhage, acute hematometra, and retained tissue are among the more common complications. Referral back to the original abortion provider for management is advisable. Overall, induced abortion does not lead to late sequelae, either medical or psychiatric. Of importance, no link exists between induced abortion and later breast cancer. For physicians who are asked to help with a referral, the National Abortion Federation and Planned Parenthood Federation of America have helpful Web sites and networks of high-quality clinics. The cost of abortion (currently about 372 dollars at 10 weeks) has decreased in recent decades. Provision of ongoing contraception and encouragement of emergency contraception can reduce unintended pregnancies and the need for abortion.
Analysis and Results from a Flush Airdata Sensing (FADS) System in Close Proximity to Firing Rocket Nozzles

This presentation presents information regarding the nose-cap flush airdata sensing (FADS) system on Orion's Pad Abort 1 (PA-1) vehicle. The purpose of the nose-cap FADS system was to test whether or not useful data could be obtained from a FADS system if it was placed in close proximity to firing rockets nozzles like the attitude control motor (ACM) nozzles on the PA-1 launch abort system (LAS). The nose-cap FADS systems use pressure measurements from a series of pressure ports which are arranged in a cruciform pattern and flush with the surface of the vehicle to estimate values of angle of attack, angle of side-slip, Mach number, impact pressure and free-stream static pressure.

An on-going debate of whether or not to legalize abortion has not stopped the number of abortion cases decreases. New practices of abortion such as online abortion has been a growing trend among teenagers. This study aims to determine how teenagers use social media such as Facebook, YouTube and Wikipedia for the practice of abortion. This study adopted online research methods (ORMs), a qualitative approach 2.0 by hacking analytical perspective developed. This study establishes online teen abortion as a research subject. This study finds patterns of online abortions among teenagers covering characteristics of teenagers as perpetrators, styles of communication, and their implication toward policy, particularly Electronic Transaction Information (ETI) regulation. Implications for online abortion behavior among teenagers through social media. The potential abortion client especially girls find practical, fast, effective, and efficient solutions that keep their secret. One of prevention patterns that has been done by some people who care about humanity and anti-abortion in the online world is posting a anti-abortion text, video or picture, anti-sex-free (anti -free intercourse before marriage) in an interesting, educative, and friendly ways.
Trying to prevent abortion.

PubMed

Bromham, D R; Oloto, E J

1997-06-01

It is known that, since antiquity, women confronted with an unwanted pregnancy have used abortion as a means of resolving their dilemma. Although undoubtedly widely used in all historical ages, abortion has come to be regarded as an event preferably avoided because of the impact on the women concerned as well as considerations for fetal life. Policies to reduce numbers and rates of abortion must acknowledge certain observations. Criminalization does not prevent abortion but increases maternal risks. A society's 'openness' in discussing sexual matters inversely correlates with abortion rates. Correlation between contraceptive use and abortion is also inverse but relates most closely to the efficacy of contraceptive methods used. 'Revolution' in the range of contraceptive methods used will have an equivalent impact on abortion rates. Secondary or emergency contraceptive methods have a considerable role to play in the reduction of abortion numbers. Good sex (and 'relationships') education programs may delay sexual debut, increase contraceptive usage and be associated with reduced abortion. Finally, interaction between socioeconomic factors and the choice between abortion and ongoing pregnancy are complex. Abortion is not necessarily chosen by those least able to support a child financially.
Access to Medication Abortion Among California's Public University Students.

Upadhyay, Ushma D; Cartwright, Alice F; Johns, Nicole E

2018-06-09

A proposed California law will require student health centers at public universities to provide medication abortion. To understand its potential impact, we sought to describe current travel time, costs, and wait times to access care at the nearest abortion facilities. We projected total medication abortion use based on campus enrollment figures and age- and state-adjusted abortion rates. We calculated distance and public transit time from campuses to the nearest abortion facility. We contacted existing abortion-providing facilities to determine costs, insurance acceptance, and wait times. We estimate 322 to 519 California public university students seek medication abortions each month. As many as 62% of students at these universities were more than 30 minutes from the closest abortion facility via public transportation. Average cost of medication abortion was $604, and average wait time to the first available appointment was one week. College students face cost, scheduling, and travel barriers to abortion care. Offering medication abortion on campus could reduce these barriers. Copyright © 2018 Society for Adolescent Health and Medicine. Published by Elsevier Inc. All rights reserved.
Trends of abortion complications in a transition of abortion law revisions in Ethiopia.

Evidence from developed countries has shown that abortion-related mortality and morbidity has decreased with the liberalization of the abortion law. This study aimed to assess the trend of hospital-based abortion complications during the transition of legalization in Ethiopia in May 2005. Medical records of women with abortion complications from 2003 to 2007 were reviewed (n = 773). Abortion and its complications with regard to legalization were described by rates and ratios, and predictors of fatal outcomes were analyzed by logistic regression. The overall and abortion-related maternal mortality ratios (AMMRs) showed a non-statistically significant downward trend over the 5-year period. However, the case fatality rate of abortion increased from 1.1% in 2003 to 3.6% in 2007. Late gestational age, history of interference and presenting after new abortion legislation passed have been found to be significant predictors of mortality. Decreased trends of abortion ratio and the AMMR were identified, but the severity of abortion complications and the case fatality rate increased during the transition of legal revision.

Queering abortion rights: notes from Argentina.

PubMed

Sutton, Barbara; Borland, Elizabeth

2018-03-06

In recent years, there have been calls in activist spaces to 'queer' abortion rights advocacy and to incorporate non-normative notions of gender identity and sexuality into abortion struggles and services. Argentina provides an interesting site in which to examine these developments, since there is a longstanding movement for abortion rights in a context of illegal abortion and a recent ground-breaking Gender Identity Law that recognises key trans rights. In this paper, we analyse public documents from the abortion rights movement's main coalition - the National Campaign for the Right to Legal, Safe and Free Abortion - alongside interviews with 19 Campaign activists to examine shifts and tensions in contemporary abortion rights activism. We trace the incorporation of trans-inclusive language into the newly proposed abortion rights bill and conclude by pointing to contextual factors that may limit or enhance the further queering of abortion rights.
A review of evidence for safe abortion care.

The provision of safe abortion services to women who need them has the potential to drastically reduce or eliminate maternal deaths due to unsafe abortion. The World Health Organization recently updated its evidence-based guidance for safe and effective clinical practices using data from systematic reviews of the literature. Systematic reviews pertaining to the evidence for safe abortion services, from pre-abortion care, medical and surgical methods of abortion and post-abortion care were evaluated for relevant outcomes, primarily those relating to safety, effectiveness and women's preference. Sixteen systematic reviews were identified and evaluated. The available evidence does not support the use of pre-abortion ultrasound to increase safety. Routine use of cervical preparation with osmotic dilators, mifepristone or misoprostol after 14 weeks gestation reduces complications; at early gestational ages, surgical abortions have very few complications. Prophylactic antibiotics result in lower rates of post-surgical abortion infection. Pain medication such as non-steroidal anti-inflammatories should be offered to women undergoing abortion procedures; acetaminophen, however, is not effective in reducing pain. Women who are eligible should be offered a choice between surgical (vacuum aspiration or dilation and evacuation) and medical methods (mifepristone and misoprostol) of abortion when possible. Modern methods of contraception can be safely initiated immediately following abortion procedures. Evidence-based guidelines assist health care providers and policymakers to utilize the best data available to provide safe abortion care and prevent the millions of deaths and disabilities that result from unsafe abortion.

Incidence of induced abortion in Malawi, 2015.

In Malawi, abortion is legal only if performed to save a woman's life; other attempts to procure an abortion are punishable by 7-14 years imprisonment. Most induced abortions in Malawi are performed under unsafe conditions, contributing to Malawi's high maternal mortality ratio. Malawians are currently debating whether to provide additional exceptions under which an abortion may be legally obtained. An estimated 67,300 induced abortions occurred in Malawi in 2009 (equivalent to 23 abortions per 1,000 women aged 15-44), but changes since 2009, including dramatic increases in contraceptive prevalence, may have impacted abortion rates. We conducted a nationally representative survey of health facilities to estimate the number of cases of post-abortion care, as well as a survey of knowledgeable informants to estimate the probability of needing and obtaining post-abortion care following induced abortion. These data were combined with national population and fertility data to determine current estimates of induced abortion and unintended pregnancy in Malawi using the Abortion Incidence Complications Methodology. We estimate that approximately 141,044 (95% CI: 121,161-160,928) induced abortions occurred in Malawi in 2015, translating to a national rate of 38 abortions per 1,000 women aged 15-49 (95% CI: 32 to 43); which varied by geographical zone (range: 28-61). We estimate that 53% of pregnancies in Malawi are unintended, and that 30% of unintended pregnancies end in abortion. Given the challenges of estimating induced abortion, and the assumptions required for calculation, results should be viewed as approximate estimates, rather than exact measures. The estimated abortion rate in 2015 is higher than in 2009 (potentially due to methodological differences), but similar to recent estimates from nearby countries including Tanzania (36), Uganda (39), and regional estimates in Eastern and Southern Africa (34-35). Over half of pregnancies in Malawi are unintended. Our findings should inform ongoing efforts to reduce maternal morbidity and mortality and to improve public health in Malawi.

Background In Malawi, abortion is legal only if performed to save a woman’s life; other attempts to procure an abortion are punishable by 7–14 years imprisonment.

Standardizing the classification of abortion incidents: the Procedural Abortion Incident Reporting and Surveillance (PAIRS) Framework.

To develop and validate standardized criteria for assessing abortion-related incidents (adverse events, morbidities, near misses) for first-trimester aspiration abortion procedures and to demonstrate the utility of a standardized framework [the Procedural Abortion Incident Reporting & Surveillance (PAIRS) Framework] for estimating serious abortion-related adverse events. As part of a California-based study of early aspiration abortion provision conducted between 2007 and 2013, we developed and validated a standardized framework for defining and monitoring first-trimester (≤14weeks) aspiration abortion morbidity and adverse events using multiple methods: a literature review, framework criteria testing with empirical data, repeated expert reviews and data-based revisions to the framework. The final framework distinguishes incidents resulting from procedural abortion care (adverse events) from morbidity related to pregnancy, the abortion process and other nonabortion related conditions. It further classifies incidents by diagnosis (confirmatory data, etiology, risk factors), management (treatment type and location), timing (immediate or delayed), seriousness (minor or major) and outcome. Empirical validation of the framework using data from 19,673 women receiving aspiration abortions revealed almost an equal proportion of total adverse events (n=205, 1.04%) and total abortion- or pregnancy-related morbidity (n=194, 0.99%). The majority of adverse events were due to retained products of conception (0.37%), failed attempted abortion (0.15%) and postabortion infection (0.17%). Serious or major adverse events were rare (n=11, 0.06%). Distinguishing morbidity diagnoses from adverse events using a standardized, empirically tested framework confirms the very low frequency of serious adverse events related to clinic-based abortion care. The PAIRS Framework provides a useful set of tools to systematically classify and monitor abortion-related incidents for first-trimester aspiration abortion procedures. Standardization will assist healthcare providers, researchers and policymakers to anticipate morbidity and prevent abortion adverse events, improve care metrics and enhance abortion quality.

The impact of a liberalisation law on legally induced abortion hospitalisations.

Legal abortion based purely in maternal option without fetal/maternal pathology was liberalised in Portugal in 2007 and since then abortion rates have increased substantially. The aim of this paper was to study the impact of the liberalisation of abortion by maternal request on total legal abortion related hospitalisation trends. We considered hospitalisations of legal abortion (ICD-9-CM codes 635.x) with discharges from 2000 to 2014. Data was obtained from a Portuguese administrative database, which contains all registered public hospitalisations in mainland Portugal. Performed legal abortions during the same period were obtained from INE (National Statistics Institute). Hospitalisations per abortion were calculated by dividing the number of legal abortions hospitalisations per the number of legal abortions, mean ages, number of hospitalisations per age group, complications, admission type and length of stay were also analysed, throughout the study period. Hospitalisations rose during the study period, (from 618 episodes in 2000 to 1,259 in 2014, with a peak of 1,603 in 2010). Since the liberalisation law was passed there was a significant decrease in the number of hospitalisations per abortion: from 1.07 in 2000 to 0.11 in 2014 (p<0.001). Furthermore, the mean age maintained stable since liberalisation (30.8 years before 2007 and 31.0 after). Abortion related hospitalisations are more frequent in women aged 25-39. A significant decrease from the emergent to the scheduled type of admission occurred from 2000 to 2014 (from 83.5% to 56.7% of emergent admissions) (p<0.001). Complications remained stable between 2000 and 2014 and delayed or excessive haemorrhage was the most frequent (4.6%). Since the liberalisation, hospitalisations per abortion have decreased, reflecting the major impact that the liberalisation of legal abortion by maternal request had on abortion trends nationwide. Before the liberalisation, each abortion led to approximately one hospitalisation while after the liberalisation this trend shifted to approximately 10% of the number of abortions. Legal abortion related hospitalisations are more frequent in women aged between 25 and 39 years old, an older age group when compared to the one registered in all cases of legal abortions, reflecting the differences between those hospitalised and those who are not. Our study shows the impact that legal abortion by maternal request liberalisation law can bring to abortion and to hospitalisation trends. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

CDC began abortion surveillance in 1969 to document the number and characteristics of women obtaining legal induced abortions. This report summarizes and describes data voluntarily reported to CDC regarding legal induced abortions obtained in the United States in 2001. For each year since 1969, CDC has compiled abortion data by state or area of occurrence. During 1973-1997, data were received from or estimated for 52 reporting areas in the United States: 50 states, the District of Columbia, and New York City. In 1998 and 1999, CDC compiled abortion data from 48 reporting areas. Alaska, California, New Hampshire, and Oklahoma did not report, and data for these states were not estimated. In 2000 and 2001, Oklahoma again reported these data, increasing the number of reporting areas to 49. A total of 853,485 legal induced abortions were reported to CDC for 2001 from 49 reporting areas, representing a 0.5% decrease from the 857,475 legal induced abortions reported by the same 49 reporting areas for 2000. The abortion ratio, defined as the number of abortions per 1,000 live births, was 246 in 2001, compared with 245 reported for 2000. This represents a 0.4% increase in the abortion ratio. The abortion rate was 16 per 1,000 women aged 15-44 years for 2001, the same as for 2000. For both the 48 and 49 reporting areas, the abortion rate remained relatively constant during 1997-2001. The highest percentages of reported abortions were for women who were unmarried (82%), white (55%) and aged <25 years (52%). Of all abortions for which gestational age was reported, 59% were performed at < or =8 weeks' gestation and 88% at <13 weeks. From 1992 (when detailed data regarding early abortions were first collected) through 2001, steady increases have occurred in the percentage of abortions performed at < or =6 weeks' gestation. A limited number of abortions were obtained at >15 weeks' gestation, including 4.3% at 16-20 weeks and 1.4% at > or =21 weeks. A total of 35 reporting areas submitted data stating that they performed medical (nonsurgical) procedures, making up 2.9% of all reported procedures from the 45 areas with adequate reporting on type of procedure. In 2000 (the most recent year for which data are available), 11 women died as a result of complications from known legal induced abortion. No deaths were associated with known illegal abortion. During 1990-1997, the number of legal induced abortions gradually declined. When the same 48 reporting areas are compared, the number of abortions decreased during 1996-2001. In 2000 and 2001, even with one additional reporting state, the number of abortions declined slightly. In 2000, as in previous years, deaths related to legal induced abortions occurred rarely (less than one death per 100,000 abortions). Abortion surveillance in the United States continues to provide the data necessary for examining trends in numbers and characteristics of women who obtain legal induced abortions and to increase understanding of this pregnancy outcome. Policymakers and program planners use these data to improve the health and well-being of women and infants.

CDC began abortion surveillance in 1969 to document the number and characteristics of women obtaining legal induced abortions and to monitor unintended pregnancy. This report summarizes and describes data reported to CDC regarding legal induced abortions obtained in the United States in 1999. For each year since 1969, CDC has compiled abortion data by state or area of occurrence. From 1973 through 1997, data were received from or estimated for 52 reporting areas in the United States: 50 states, the District of Columbia, and New York City. Beginning in 1998, CDC compiled abortion data from 48 reporting areas. Alaska, California, New Hampshire, and Oklahoma did not report, and data for these areas were not estimated. The availability of data regarding the characteristics of women who obtained an abortion in 1999 varied by state and by the number of states reporting each characteristic. The total number of legal induced abortions is reported by state of residence and also by state of occurrence for most areas; characteristics of women obtaining abortions in 1999 are reported by state of occurrence. A total of 861,789 legal induced abortions were reported to CDC for 1999, representing a 2.5% decrease from the 884,273 legal induced abortions reported by the same 48 reporting areas for 1998. The abortion ratio, defined as the number of abortions per 1,000 live births, was 256 in 1999, compared with 264 reported for 1998; the abortion rate for these 48 reporting areas was 17 per 1,000 women aged 15-44 years for 1999, the same as in 1997 and 1998. The highest percentages of abortions were reported for women aged < 25 years, women who were white, and unmarried women; slightly more than half were obtaining an abortion for the first time. Fifty-eight percent of all abortions for which gestational age was reported were performed at < or = 8 weeks of gestation, and 88% were performed before 13 weeks. From 1992 (when these data were first collected) through 1999, increases have occurred in the percentage of abortions performed at < or = 6 weeks of gestation. Few abortions were provided after 15 weeks of gestation; 4.3% were obtained at 16-20 weeks and 1.5% were obtained at > or = 21 weeks. A total of 27 reporting areas submitted data stating that they performed medical (nonsurgical) procedures (two of these areas categorized medical abortions with "other" procedures), making up < 1.0% of all procedures reported from all reporting areas. In 1998 (for which data have not been published previously and the most recent year for which such data are available), nine women died as a result of complications from known legal induced abortion; no deaths were associated with known illegal abortion. From 1990 through 1997, the number of legal induced abortions gradually declined. In 1998 and in 1999, the number of abortions continued to decrease when comparing the same 48 reporting areas. In 1998, as in previous years, deaths related to legal induced abortions occurred rarely. Abortion surveillance in the United States should continue so that trends and characteristics of women who obtain legal induced abortions can be examined and efforts to prevent unintended pregnancy can be enhanced.
Is Induced Abortion Really Declining in Armenia?

PubMed

Jilozian, Ann; Agadjanian, Victor

2016-06-01

As in other post-Soviet settings, induced abortion has been widely used in Armenia. However, recent national survey data point to a substantial drop in abortion rates with no commensurate increase in modern contraceptive prevalence and no change in fertility levels. We use data from in-depth interviews with women of reproductive age and health providers in rural Armenia to explore possible underreporting of both contraceptive use and abortion. While we find no evidence that women understate their use of modern contraception, the analysis suggests that induced abortion might indeed be underreported. The potential for underreporting is particularly high for sex-selective abortions, for which there is growing public backlash, and medical abortion, a practice that is typically self-administered outside any professional supervision. Possible underreporting of induced abortion calls for refinement of both abortion registration and relevant survey instruments. Better measurement of abortion dynamics is necessary for successful promotion of effective modern contraceptive methods and reduction of unsafe abortion practices. © 2016 The Population Council, Inc.

Diniz, Debora; Medeiros, Marcelo

2010-06-01

This study presents the first results of the National Abortion Survey (PNA, Pesquisa Nacional de Aborto), a household random sample survey fielded in 2010 covering urban women in Brazil aged 18 to 39 years. The PNA combined two techniques, interviewer-administered questionnaires and self-administered ballot box questionnaires. The results of PNA show that at the end of their reproductive health one in five women has performed an abortion, with abortions being more frequent in the main reproductive ages, that is, from 18 to 29 years old. No relevant differentiation was observed in the practice of abortion among religious groups, but abortion was found to be more common among people with lower education. The use of medical drugs to induce abortion occurred in half of the abortions, and post-abortion hospitalization was observed among approximately half of the women who aborted. Such results lead to conclude that abortion is a priority in the Brazilian public health agenda.
Doctors or mid-level providers for abortion.

The World Health Organization recommends that abortion can be provided at the lowest level of the healthcare system. Training mid-level providers, such as midwives, nurses and other non-physician providers, to conduct first trimester aspiration abortions and manage medical abortions has been proposed as a way to increase women's access to safe abortion procedures. To assess the safety and effectiveness of abortion procedures administered by mid-level providers compared to doctors. We searched the CENTRAL Issue 7, MEDLINE and POPLINE databases for comparative studies of doctor and mid-level providers of abortion services. We searched for studies published in any language from January 1980 until 15 August 2014. Randomised controlled trials (RCTs) (clustered or not clustered), prospective cohort studies or observational studies that compared the safety or effectiveness (or both) of any type of first trimester abortion procedure, administered by any type of mid-level provider or doctors, were eligible for inclusion in the review. Two independent review authors screened abstracts for eligibility and double-extracted data from the included studies using a pre-tested form. We meta-analysed primary outcome data using both fixed-effect and random-effects models to obtain pooled risk ratios (RR) with 95% confidence intervals (CIs). We carried out separate analyses by study design (RCT or cohort) and type of abortion procedure (medical versus surgical). Eight studies involving 22,018 participants met our eligibility criteria. Five studies (n = 18,962) assessed the safety and effectiveness of surgical abortion procedures administered by mid-level providers compared to doctors. Three studies (n = 3056) assessed the safety and effectiveness of medical abortion procedures. The surgical abortion studies (one RCT and four cohort studies) were carried out in the United States, India, South Africa and Vietnam. The medical abortion studies (two RCTs and one cohort study) were carried out in India, Sweden and Nepal. The studies included women with gestational ages up to 14 weeks for surgical abortion and nine weeks for medical abortion.Risk of selection bias was considered to be low in the three RCTs, unclear in four observational studies and high in one observational study. Concealment bias was considered to be low in the three RCTs and high in all five observational studies. Although none of the eight studies performed blinding of the participants to the provider type, we considered the performance bias to be low as this is part of the intervention. Detection bias was considered to be high in all eight studies as none of the eight studies preformed blinding of the outcome assessment. Attrition bias was low in seven studies and high in one, with over 20% attrition. We considered six studies to have unclear risk of selective reporting bias as their protocols had not been published. The remaining two studies had published their protocols. Few other sources of bias were found.Based on an analysis of three cohort studies, the risk of surgical abortion failure was significantly higher when provided by mid-level providers than when procedures were administered by doctors (RR 2.25, 95% CI 1.38 to 3.68), however the quality of evidence for this outcome was deemed to be very low. For surgical abortion procedures, we found no significant differences in the risk of complications between mid-level providers and doctors (RR 0.99, 95% CI 0.17 to 5.70 from RCTs; RR 1.38, 95% CI 0.70 to 2.72 from observational studies). When we combined the data for failure and complications for surgical abortion we found no significant differences between mid-level providers and doctors in both the observational study analysis (RR 1.36, 95% CI 0.86 to 2.14) and the RCT analysis (RR 3.07, 95% CI 0.16 to 59.08). The quality of evidence of the outcome for RCT studies was considered to be low and for observational studies very low. For medical abortion procedures the risk of failure was not different for mid-level providers or doctors (RR 0.81, 95% CI 0.48 to 1.36 from RCTs; RR 1.09, 95% CI 0.63 to 1.88 from observational studies). The quality of evidence of this outcome for the RCT analysis was considered to be high, although the quality of evidence of the observational studies was considered to be very low. There were no complications reported in the three medical abortion studies. There was no statistically significant difference in the risk of failure for medical abortions performed by mid-level providers compared with doctors. Observational data indicate that there may be a higher risk of abortion failure for surgical abortion procedures administered by mid-level providers, but the number of studies is small and more robust data from controlled trials are needed. There were no statistically significant differences in the risk of complications for first trimester surgical abortions performed by mid-level providers compared with doctors.
Abortion Stigma Among Low-Income Women Obtaining Abortions in Western Pennsylvania: A Qualitative Assessment.

Abortion stigma may cause psychological distress in women who are considering having an abortion or have had one. This phenomenon has been relatively underexplored in low-income women, who may already be at an increased risk for poor abortion-related outcomes because of difficulties accessing timely and safe abortion services. A qualitative study conducted between 2010 and 2013 used semistructured interviews to explore pregnancy intentions among low-income women recruited from six reproductive health clinics in Western Pennsylvania. Transcripts from interviews with 19 participants who were planning to terminate a pregnancy or had had an abortion in the last two weeks were examined through content analysis to identify the range of attitudes they encountered that could contribute to or reflect abortion stigma, the sources of these attitudes and women's responses to them. Women commonly reported that partners, family members and they themselves held antiabortion attitudes. Such attitudes communicated that abortion is morally reprehensible, a rejection of motherhood, rare and thus potentially deviant, detrimental to future fertility and an irresponsible choice. Women reacted to external and internal negative attitudes by distinguishing themselves from other women who obtain abortions, experiencing negative emotions, and concealing or delaying their abortions. Women's reactions to antiabortion attitudes may perpetuate abortion stigma. Further research is needed to inform interventions to address abortion stigma and improve women's abortion experiences.

Biggs, M. Antonia; Ralph, Lauren; Gerdts, Caitlin; Roberts, Sarah; Glymour, M. Maria

2018-01-01

Objectives. To determine the socioeconomic consequences of receipt versus denial of abortion. Methods. Women who presented for abortion just before or after the gestational age limit of 30 abortion facilities across the United States between 2008 and 2010 were recruited and followed for 5 years via semiannual telephone interviews. Using mixed effects models, we evaluated socioeconomic outcomes for 813 women by receipt or denial of abortion care. Results. In analyses that adjusted for the few baseline differences, women denied abortions who gave birth had higher odds of poverty 6 months after denial (adjusted odds ratio [AOR] = 3.77; P < .001) than did women who received abortions; women denied abortions were also more likely to be in poverty for 4 years after denial of abortion. Six months after denial of abortion, women were less likely to be employed full time (AOR = 0.37; P = .001) and were more likely to receive public assistance (AOR = 6.26; P < .001) than were women who obtained abortions, differences that remained significant for 4 years. Conclusions. Women denied an abortion were more likely than were women who received an abortion to experience economic hardship and insecurity lasting years. Laws that restrict access to abortion may result in worsened economic outcomes for women. PMID:29345993

Background This study prospectively assesses the mental health outcomes among women seeking abortions, by comparing women having later abortions to women denied abortions, up to two years post-abortion seeking. Methods We present the first two years of a 5-year telephone interview study that is following 956 women who sought an abortion from 30 facilities throughout the U.S. We use adjusted linear mixed effects regression analyses to assess whether symptoms of depression and anxiety, as measured by the BSI-short form and Prime-MD, differ over time among women denied an abortion due to advanced gestational age, compared to women who received abortions. Results Baseline predicted mean depressive symptom scores for women denied abortion (3.07) were similar to women receiving an abortion just below the gestational limit (2.86). Depressive symptoms declined over time with no difference between groups. Initial predicted mean anxiety symptoms were higher among women denied care (2.59) than among women who had an abortion just below the gestational limit (1.91). Anxiety levels in the two groups declined and converged after one year. Conclusions Women who received an abortion had similar or lower levels of depression and anxiety than women denied an abortion. Our findings do not support the notion that abortion is a cause of mental health problems. PMID:25628123

We use adjusted linear mixed-effects regression analyses to assess whether symptoms of depression and anxiety, as measured by the Brief Symptom Inventory-short form and the Primary Care Evaluation of Mental Disorders Patient Health Questionnaire, differ over time among women denied an abortion due to advanced gestational age, compared with women who received abortions. Baseline predicted mean depressive symptom scores for women denied abortion (3.07) were similar to women receiving an abortion just below the gestational limit (2.86). Depressive symptoms declined over time, with no difference between groups. Initial predicted mean anxiety symptoms were higher among women denied care (2.59) than among women who had an abortion just below the gestational limit (1.91). Anxiety levels in the two groups declined and converged after 1 year. Women who received an abortion had similar or lower levels of depression and anxiety than women denied an abortion. Our findings do not support the notion that abortion is a cause of mental health problems.
