    HLA-antigens are extremely polymorphic. A calculation of the polymorphism shows a number of 398.476.343 possible HLA-phenotypes, if HLA-A, -B, -C and -DR antigens are taken into account. The compatibility of HLA-antigens of recipient and donor plays a crucial role in transplantation: HLA-antigens are the traits, which are recognized by the immune system of the recipient in the frame of a rejection of the transplant or by the donor in the frame of a graft-versus-host reaction. Large international statistics show that HLA-incompatibility between recipient and donor leads to short transplant function periods, while compatibility brings about good transplant function. Therefore, matching of HLA-antigens plays an important role in transplantation of solid organs, mainly kidneys (3, 4, 5), and is completely necessary in bone marrow transplantation. Also in pregnancy, HLA-antigens are important: If HLA compatibility between mother and child is high, the risk for habitual abortion is higher than in normal pregnancies (6, 7).

    Full Text Available Thyroid autoimmunity (TAI appears to be a determining factor in pregnancy loss. Many studies have confirmed this association, not only in hypo- and hyperthyroid women but also in euthyroid ones. The main risk associated with TAI is the occurrence of maternal hypothyroidism, with its potential deleterious effects for both the mother and fetus. We report a case of a 35-years-old woman with a history of habitual abortion. After diagnosis of TAI with normal thyroid function and treatment with levothyroxine, the patient became pregnant. After a normal pregnancy without problems, she gave birth of normal fetus at 39’ weeks gestation.

    Sudden sensorineural hearing loss (SSNHL) is usually unilateral and can be associated with tinnitus and vertigo. The most common causes of this disease are known to be the vascular and viral agents, but immune disorders are involved in the development of sudden deafness. The antiphospholipid syndrome (APS) is an acquired autoimmune system disorder, which is defined as the presence of antiphospholipid antibodies (APA) in the patient's blood, then cause venous and/or arterial thrombosis in various organs of the body, for example, thrombosis can occur in the placenta and/or the inner ear. As a result, it can cause abortion and/or sudden deafness. Bilateral SSNHL following habitual abortion is a rare clinical event. Here, we report a case of 32-year-old woman who presented with bilateral sudden hearing loss following recurrent pregnancy loss (RPL) as the first manifestation of primary antiphospholipid syndrome. Combine the literature, the diagnosis, clinical implication and treatment are discussed.

    Toxoplasmosis is a zoonosis caused by Toxoplasma gondii, an obligate intracellular parasite. In pregnant women on the worldwide scale, there are seroprevalences from 7% to 51.3% and in women with abnormal pregnancies and abortions the seroprevalences vary from 17.5% to 52.3%. In Mexico, seropositivity has been found to vary from 18.2% to 44.8% in women with abnormal deliveries or abortions. This study's aim was to determine the incidence of IgG and IgM anti-Toxoplasma antibodies in women at the Gineco-Obstetrics Hospital of the Western Medical Center of the Mexican Social Security Institute. Three hundred and fifty women with high-risk pregnancies were studied, and 122 (34.9%) were found to be IgG seropositive and 76 (20.7%) were IgM positive. In one group of women with habitual abortions there were 48 (44.9%) with the presence of IgG antibodies and 33 (33.3%) were IgM seropositive. Seropositivity was analyzed according to age, occupation, socio-economic level, eating raw or poorly cooked meat, and living with cats.

    2016-12-01

    This article explores the sensory dimensions of scientific field research in the only region in the world where free-ranging bonobos ( Pan paniscus) can be studied in their natural environment; the equatorial rainforest of the Democratic Republic of Congo. If, as sensory anthropologists have argued, the senses are developed, grown and honed in a given cultural and environmental milieu, how is it that field scientists come to dwell among familiarity in a world which is, at first, unfamiliar? This article builds upon previous anthropological and philosophical engagements with habituation that have critically examined primatologists' attempts to become 'neutral objects in the environment' in order to habituate wild apes to their presence. It does so by tracing the somatic modes of attention developed by European and North American researchers as they follow bonobos in these forests. The argument is that as environments, beings and their elements become familiar, they do not become 'neutral', but rather, suffused with meaning.

  4. Habituation of reinforcer effectiveness

    Directory of Open Access Journals (Sweden)

    David R Lloyd

    2014-01-01

    Full Text Available In this paper we propose an integrative model of habituation of reinforcer effectiveness (HRE that links behavioral and neural based explanations of reinforcement. We argue that habituation of reinforcer effectiveness (HRE is a fundamental property of reinforcing stimuli. Most reinforcement models implicitly suggest that the effectiveness of a reinforcer is stable across repeated presentations. In contrast, an HRE approach predicts decreased effectiveness due to repeated presentation. We argue that repeated presentation of reinforcing stimuli decreases their effectiveness and that these decreases are described by the behavioral characteristics of habituation (McSweeney and Murphy, 2009;Rankin et al., 2009. We describe a neural model that postulates a positive association between dopamine neurotransmission and HRE. We present evidence that stimulant drugs, which artificially increase dopamine neurotransmission, disrupt (slow normally occurring HRE and also provide evidence that stimulant drugs have differential effects on operant responding maintained by reinforcers with rapid vs. slow HRE rates. We hypothesize that abnormal HRE due to genetic and/or environmental factors may underlie some behavioral disorders. For example, recent research indicates that slow-HRE is predictive of obesity. In contrast ADHD may reflect ‘accelerated-HRE’. Consideration of HRE is important for the development of effective reinforcement based treatments. Finally, we point out that most of the reinforcing stimuli that regulate daily behavior are non-consumable environmental/social reinforcers which have rapid-HRE. The almost exclusive use of consumable reinforcers with slow-HRE in pre-clinical studies with animals may have caused the importance of HRE to be overlooked. Further study of reinforcing stimuli with rapid-HRE is needed in order to understand how habituation and reinforcement interact and regulate behavior.

    Habituation is a filter that optimizes the processing of information by our brain in all sensory modalities. It results in an unconscious reduced responsiveness to continuous or repetitive stimulation. In olfaction, the main question is whether habituation works the same way for any odorant or whether we habituate differently to each odorant? In particular, whether chemical, physical or perceptual cues can limit or increase habituation. To test this, the odour intensity of 32 odorants differing in physicochemical characteristics was rated by 58 participants continuously during 120s. Each odorant was delivered at a constant concentration. Results showed odorants differed significantly in habituation, highlighting the multifactoriality of habituation. Additionally habituation was predicted from 15 physico-chemical and perceptual characteristics of the odorants. The analysis highlighted the importance of trigeminality which is highly correlated to intensity and pleasantness. The vapour pressure, the molecular weight, the Odor Activity Value (OAV) and the number of double bonds mostly contributed to the modulation of habituation. Moreover, length of the carbon chain, number of conformers and hydrophobicity contributed to a lesser extent to the modulation of habituation. These results highlight new principles involved in the fundamental process of habituation, notably trigeminality and the physicochemical characteristics associated.

  7. Abortion ethics.

    Science.gov (United States)

    Fromer, M J

    1982-04-01

    Nurses have opinions about abortion, but because they are health professionals and their opinions are sought as such, they are obligated to understand why they hold certain views. Nurses need to be clear about why they believe as they do, and they must arrive at a point of view in a rational and logical manner. To assist nurses in this task, the ethical issues surrounding abortion are enumerated and clarified. To do this, some of the philosophic and historic approaches to abortion and how a position can be logically argued are examined. At the outset some emotion-laden terms are defined. Abortion is defined as the expulsion of a fetus from the uterus before 28 weeks' gestation, the arbitrarily established time of viability. This discussion is concerned only with induced abortion. Since the beginning of recorded history women have chosen to have abortions. Early Jews and Christians forbade abortion on practical and religious grounds. A human life was viewed as valuable, and there was also the practical consideration of the addition of another person to the population, i.e., more brute strength to do the necessary physical work, defend against enemies, and ensure the continuation of the people. These kinds of pragmatic reasons favoring or opposing abortion have little to do with the Western concept of abortion in genaeral and what is going on in the U.S. today in particular. Discussion of the ethics of abortion must rest on 1 or more of several foundations: whether or not the fetus is a human being; the rights of the pregnant woman as opposed to those of the fetus, and circumstances of horror and hardship that might surround a pregnancy. Viability is relative. Because viability is not a specific descriptive entity, value judgments become part of the determination, both of viability and the actions that might be taken based on that determination. The fetus does not become a full human being at viability. That occurs only at conception or birth, depending on one's view

    1998-10-01

    Infertility is felt nowadays as a personal affront, quite intolerable, and RSA are an emblematic example of that personal and social failure, failure of the woman and of the couple, failure of the doctor too, failure of their common project. No wonder if those recurrences open the way to the problem of cause and/or consequences for those women whose pregnancy regularly begins and as regularly sees its evolution thwarted. The hypothesis of a psychological factor not excluding but rather potentialising a somatic one, should work as an incentive to important predictive studies, the best means for prevention. Whatever our present medical possibilities, the emphasis should always be on attentive listening and counselling, so as to mingle in judicious harmony "hightech" science and "tender love and care".

  10. Habituation and 1/f Noise

    West, Bruce; Grigolini, Paolo

    2010-03-01

    We present a model to explain the psychophysical phenomena of habituation using methods from non-equilibrium statistical physics and complex network theory. Habituation is a ubiquitous and extremely simple from of learning through which animals, including humans; learn to disregard stimuli that are no longer novel, thereby allowing them to attend to new stimuli.Herein we present a statistical habituation model (SHM) based on a generalization of linear response theory and discrete events using renewal theory. The SHM introduces a theory of the effective synaptic weight connecting two neuron networks, with the synaptic weight being described by a time series with inverse power-law statistics. The statistics determine the distribution of time intervals between events, which in a complex neuronal network leads to neuronal avalanches, see e.g., Beggs and Plenz (J. Neurosci 23, 11167, 2003). The SHM establishes that the fundamental mechanism producing habituation in its myriad of forms is the 1/f-nose that is generically produced in individual neurons and in complex neuronal networks. Both simple harmonic and more complicated stimuli are shown to habituate (decay) as inverse power laws with indices determined by the power-law index of the effective synaptic statistical distribution. This is the first theory that directly relates the psychophysical phenomenon of habituation to the dynamics of the brain.

  12. Habituation, sensitization and Pavlovian conditioning

    Directory of Open Access Journals (Sweden)

    Münire Özlem Çevik

    2014-02-01

    Full Text Available In this brief review, I argue that the impact of a stimulus on behavioral control increase as the distance of the stimulus to the body decreases. Habituation, i.e., decrement in response intensity repetition of the triggering stimulus, is the default state for sensory processing, and the likelihood of habituation is higher for distal stimuli. Sensitization, i.e., increment in response intensity upon stimulus repetition, occurs in a state dependent manner for proximal stimuli that make direct contact with the body. In Pavlovian conditioning paradigms, the US is always a more proximal stimulus than the CS. The mechanisms of associative and non-associative learning are not independent. CS-US pairings lead to formation of associations if sensitizing modulation from a proximal US prevents the habituation for a distal anticipatory CS.

  13. Sensitization and habituation regulate reinforcer effectiveness.

    Science.gov (United States)

    McSweeney, Frances K; Murphy, Eric S

    2009-09-01

    We argue that sensitization and habituation occur to the sensory properties of reinforcers when those reinforcers are presented repeatedly or for a prolonged time. Sensitization increases, and habituation decreases, the ability of a reinforcer to control behavior. Supporting this argument, the rate of operant responding changes systematically within experimental sessions even when the programmed rate of reinforcement is held constant across the session. These within-session changes in operant responding are produced by repeated delivery of the reinforcer, and their empirical characteristics correspond to the characteristics of behavior undergoing sensitization and habituation. Two characteristics of habituation (dishabituation, stimulus specificity) are particularly useful in separating habituation from alternative explanations. Arguing that habituation occurs to reinforcers expands the domain of habituation. The argument implies that habituation occurs to biologically important, not just to neutral, stimuli. The argument also implies that habituation may be observed in "voluntary" (operant), not just in reflexive, behavior. Expanding the domain of habituation has important implications for understanding operant and classical conditioning. Habituation may also contribute to the regulation of motivated behaviors. Habituation provides a more accurate and a less cumbersome explanation for motivated behaviors than homeostasis. Habituation also has some surprising, and easily testable, implications for the control of motivated behaviors.

    2015-11-01

    A safe induced abortion has no impact on future fertility. Ovulation may resume as early as 8 days after the abortion. There is no difference in return to fertility after medical or surgical abortion. Most women resume sexual activity soon after an abortion. Contraceptive counseling and provision should therefore be an integrated part of the abortion services to help women avoid another unintended pregnancy and risk, in many cases an unsafe, abortion. Long-acting reversible contraceptive methods that includes implants and intrauterine contraception have been shown to be the most effective contraceptive methods to help women prevent unintended pregnancy following an abortion. However, starting any method is better than starting no method at all. This Special Report will give a short guide to available methods and when they can be started after an induced abortion.

    2009-08-01

    Abortion stigma is widely acknowledged in many countries, but poorly theorised. Although media accounts often evoke abortion stigma as a universal social fact, we suggest that the social production of abortion stigma is profoundly local. Abortion stigma is neither natural nor 'essential' and relies upon power disparities and inequalities for its formation. In this paper, we identify social and political processes that favour the emergence, perpetuation and normalisation of abortion stigma. We hypothesise that abortion transgresses three cherished 'feminine' ideals: perpetual fecundity; the inevitability of motherhood; and instinctive nurturing. We offer examples of how abortion stigma is generated through popular and medical discourses, government and political structures, institutions, communities and via personal interactions. Finally, we propose a research agenda to reveal, measure and map the diverse manifestations of abortion stigma and its impact on women's health.

    2015-06-01

    In two conditioned suppression experiments with a latent inhibition (LI) design, we measured the habituation of rats in preexposure, their LI during conditioning, and then extinction over days. In the first experiment, lick suppression, the preexposed group (PE) showed a significant initial unconditioned response (UR) to the target stimulus and significant long-term habituation (LTH) of that response over days. The significant difference between the PE and nonpreexposed (NPE) groups on the first conditioning trial was due solely to the difference in their URs to the conditioned stimulus (CS)-a habituated response (PE) and an unhabituated response (NPE). In the second experiment, bar-press suppression, little UR to the target stimulus was apparent during preexposure, and no detectable LTH. Thus, there was no difference between the PE and NPE groups on the first conditioning trial. Whether the UR to the CS confounds the interpretation of LI (Exp. 1) or not (Exp. 2) can only be known if the UR is measured. In both experiments, LI was observed in acquisition. Also in both experiments, rats that were preexposed and then conditioned to asymptote were significantly more resistant to extinction than were the rats not preexposed. This result contrasts with the consistently reported finding that preexposure either produces less resistance to extinction or has no effect on extinction. The effect of stimulus preexposure survived conditioning to asymptote and was reflected directly in extinction. These two experiments provide a cautionary procedural note for LI experiments and have shown an unexpected extinction effect that may provide new insights into the interpretation of LI.

  1. Abortion: the continuing controversy.

    Science.gov (United States)

    Behrens, C E

    1972-08-01

    While most countries of the world practice abortion, government policy, medical opinion, private opinion and actual practice vary widely. Although mortality from legal abortions is quite low, complications rise sharply after 12 gestational weeks. No conclusive proof shows adverse postabortion psychological effects. Romania, Japan and the Soviet Union experienced declining birth rates when abortion was made available and New York City saw a decline in illegitimacy of approximately 12% from 1970 to 1971. Throughout the world abortion laws vary from restrictive to moderate to permissive. Where laws are restrictive, as in France and Latin America, illegal abortions are estimated in the millions. The controversy over abortion centers around the arguments of what constitutes a human life, and the rights of the fetus versus the right of a woman to control her reproductive life. A review of state abortion laws as of August 1972 shows pressure on state legislatures to change existing laws. The future of abortion depends upon technological advances in fertility control, development of substitutes like menstral extraction, prostaglandins and reversible sterilization. Development of these techniques will take time. At present only through education and improved delivery of contraceptives can dependence on abortion as a method of fertility control be eased. Citizen education in the United States, both sex education and education for responsbile parenthood, is in a poor state according to the Commission on Population Growth and the American Future. If recourse to abortion is to be moderated, it is the next generation of parents who will have to be educated.

    Diniz, D; Gonzalez Velez, A C

    1998-06-01

    Although abortion has been the most debated of all issues analyzed in bioethics, no moral consensus has been achieved. The problem of abortion exemplifies the difficulty of establishing social dialogue in the face of distinct moral positions, and of creating an independent academic discussion based on writings that are passionately argumentative. The greatest difficulty posed by the abortion literature is to identify consistent philosophical and scientific arguments amid the rhetorical manipulation. A few illustrative texts were selected to characterize the contemporary debate. The terms used to describe abortion are full of moral meaning and must be analyzed for their underlying assumptions. Of the four main types of abortion, only 'eugenic abortion', as exemplified by the Nazis, does not consider the wishes of the woman or couple--a fundamental difference for most bioethicists. The terms 'selective abortion' and 'therapeutic abortion' are often confused, and selective abortion is often called eugenic abortion by opponents. The terms used to describe abortion practitioners, abortion opponents, and the 'product' are also of interest in determining the style of the article. The video entitled "The Silent Scream" was a classic example of violent and seductive rhetoric. Its type of discourse, freely mixing scientific arguments and moral beliefs, hinders analysis. Within writings about abortion three extreme positions may be identified: heteronomy (the belief that life is a gift that does not belong to one) versus reproductive autonomy; sanctity of life versus tangibility of life; and abortion as a crime versus abortion as morally neutral. Most individuals show an inconsistent array of beliefs, and few groups or individuals identify with the extreme positions. The principal argument of proponents of legalization is respect for the reproductive autonomy of the woman or couple based on the principle of individual liberty, while heteronomy is the main principle of

    Sirois, Sylvain; Mareschal, Denis

    2004-10-01

    Habituation and related procedures are the primary behavioral tools used to assess perceptual and cognitive competence in early infancy. This article introduces a neurally constrained computational model of infant habituation. The model combines the two leading process theories of infant habituation into a single functional system that is grounded in functional brain circuitry. The HAB model (for Habituation, Autoassociation, and Brain) proposes that habituation behaviors emerge from the opponent, complementary processes of hippocampal selective inhibition and cortical long-term potentiation. Simulations of a seminal experiment by Fantz [Visual experience in infants: Decreased attention familiar patterns relative to novel ones. Science, 146, 668-670, 1964] are reported. The ability of the model to capture the fine detail of infant data (especially age-related changes in performance) underlines the useful contribution of neurocomputational models to our understanding of behavior in general, and of early cognition in particular.

    1985-09-01

    This article reviews the difficult but complex subject of abortion in adolescents. Methods of abortion are outlined and additional aspects are presented: psychological effects, counseling issues, and legal parameters. It is our conclusion that intense efforts should be aimed at education of youth about sexuality and prevention of pregnancy, utilizing appropriate contraceptive services. When confronted with a youth having an unwanted pregnancy, all legal options need to be carefully explored: delivery, adoption, or abortion. The decision belongs to the youth and important individuals in her environment. Understanding developmental aspects of adolescence will help the clinician deal with the pregnant teenagers. If abortion is selected, a first trimester procedure is best. Finally, physicians are urged to be aware of the specific, ever changing legal dynamics concerning this subject which are present in their states. Abortion is a phenomenon which has become an emotional but undeniably important aspect of adolescent sexuality and adolescent health care, in this country and around the world.

    2000-12-01

    Little information exists on the impact of induced abortion on psychosexuality. Negative psychological effects and psychiatric complications due to termination of pregnancy seem to be rare. The objective of this study was to review the impact of induced abortion on sexuality and couple relationships. A systematic search of the literature was performed. Studies had to report a quantitative or qualitative evaluation of sexuality after pregnancy termination. Four studies were included. In the one prospective study using a control group, no difference in sexual functioning between groups after 1 year was reported. In the remaining observational studies, sexual dysfunction was reported in up to 30% of women after termination. Women undergoing abortion had significantly more conflicts in their partnerships. This was similar in all studies. Separation occurred in about one-quarter of all couples. Some studies report sexual dysfunction after termination of pregnancy. In about half of the couples separated after termination, abortion seemed not to have led to the separation. Psychological factors, together with relationship problems, might have played a role in failed contraception. The impact of induced abortion on sexuality needs to be studied in greater detail with rigorous methodology to draw firm conclusions.

  12. Legal abortion in Georgia, 1980.

    Spitz, A M; Oberle, M; Zaro, S M

    1984-02-01

    According to data reported to the Georgia Department of Human Resources (DHR), the number of induced abortions performedin Georgia in 1980 decreased for the 1st time since 1968 when the state legalized abortion. To verify this reported decrease, the DHR data were compared with statistics obtained by the Alan Guttmacher Institute in a 1980 survey of abortion providers in Georgia. Since the AGI contacts providers directly, its statistics are considered a more accurate reflection of abortions performed. According to the DHR, the number of abortions dropped from 36,579 in 1979 to 33,288 in 1980, a 9% decrease, and the abortion rate fell from 26.6/1000 women ages 15-44 years to 23.9/1000. AGI data indicated a drop from 38,760 abortions in 1979 to 37,890 in 1980, a 2% decrease. Since both sources noted a similar trend despite differences in data collection methods, the 1980 decline in abortion procedures in Georgia is considered to represent a true decline rather than s statistical artifact. The sociodemographic characteristics of women obtaining abortions in Georgia in 1980 were also analyzed on the basis of DHR data. Although the number of abortions in Georgia performed on Georgia residents increased 2.5% from 1979-80 to 90.7%, the abortion ratio for residents decreased from 367.7 to 327.4 abortions/1000 live births. There was little change in the age, race, or marital status distribution of women receiving abortions. The ratio for white women was 317 abortions/1000 live births and that for blacks was 342/1000. The abortion ratio for unmarried women (1166/1000) was 13 times that for married women (88/1000). The number of repeat abortions decreased form 34% in 1979 to 29% in 1980. Moreover, 93% of women obtaining abortions did so in the 1st 12 weeks of gestation compared with 89% in 1979. The percentage of abortions performed in clinics increased from 66.5% in 1979 to 75.3% in 1980, with suction curettage accounting for 85% of all abortions in the 1st 12 weeks of

    The computerized dynamic posturography (CDP) test examines the response pattern to simultaneous, multimodal sensory stimulation. The purpose of this prospective, controlled study was to investigate whether postural dynamics evaluated by CDP are related to seasickness severity and the process of habituation to sea conditions. Subjects included 74 naval personnel assigned to service aboard ship and 29 controls designated for shore-based positions. Study participants performed a baseline CDP test, and subsequent follow-up examinations 6 and 12 months after completion of their training. On those occasions they also completed a seasickness severity questionnaire. Longitudinal changes in postural parameters were examined, as well as a possible correlation between baseline CDP results and final seasickness severity scores. The results indicated longitudinal habituation to seasickness. Reduced scores were found for sensory organization sub-tests 3 and 5 in the first follow-up examination, reflecting increased weighting of visual and somatosensory input in the maintenance of balance. Scores in the second follow-up examination were above baseline values, indicating increased reliance on vestibular cues. These significant bimodal changes were found only in study subjects having the highest degree of habituation to seasickness. A significant decrease in motor response strength was found in parallel with increased habituation to seasickness. Baseline CDP results and postural control dynamics were not correlated with subjects' final seasickness severity score. These results suggest a potential role for CDP in monitoring the process of habituation to unusual motion conditions.

    Shaw, Dorothy

    2010-10-01

    Abortion has been a reality in women's lives since the beginning of recorded history, typically with a high risk of fatal consequences, until the last century when evolutions in the field of medicine, including techniques of safe abortion and effective methods of family planning, could have ended the need to seek unsafe abortion. The context of women's lives globally is an important but often ignored variable, increasingly recognised in evolving human rights especially related to gender and reproduction. International and regional human rights instruments are being invoked where national laws result in violations of human rights such as health and life. The individual right to conscientious objection must be respected and better understood, and is not absolute. Health professional organisations have a role to play in clarifying responsibilities consistent with national laws and respecting reproductive rights. Seeking common ground using evidence rather than polarised opinion can assist the future focus.

    2011-01-01

    In this article we address the issue, with a tentative empirical application to the Italian data, of the relationship, very debated mainly in north America, between abortion legalization and reduction of crime rates of youth. The rationale of this relationship is that there is a causal factor at work: the more unwanted pregnancies aborted, the less unwanted children breeding their criminal attitude in an hostile/deprived family environment. Many methodological and empirical criticisms have been raised against the proof of the existence of such a relationship: our attempt to test if this link is valid for Italy cannot endorse its existence. The data we used made necessary some assumptions and the reliability of official estimates of crime rates was debatable (probably downward biased). We conclude that, at least for Italy, the suggested relationship is unproven: other reasons for the need of legal abortion have been and should be put forward.

    This paper documents some of the evolutionary steps in developing a rigorous Space Shuttle launch abort capability. The paper addresses the abort strategy during the design and development and how it evolved during Shuttle flight operations. The Space Shuttle Program made numerous adjustments in both the flight hardware and software as the knowledge of the actual flight environment grew. When failures occurred, corrections and improvements were made to avoid a reoccurrence and to provide added capability for crew survival. Finally some lessons learned are summarized for future human launch vehicle designers to consider.

  1. Abortion and compelled physician speech.

    Informed consent mandates for abortion providers may infringe the First Amendment's freedom of speech. On the other hand, they may reinforce the physician's duty to obtain informed consent. Courts can promote both doctrines by ensuring that compelled physician speech pertains to medical facts about abortion rather than abortion ideology and that compelled speech is truthful and not misleading.

    Conclusions: Previous history of spontaneous abortion is associated with adverse pregnancy outcome. There is increased risk of abortion, preterm delivery, need for caesarean sections and fetal loss in cases of previous spontaneous abortions. These complications and fetal loss can be reduced by booking the patients and giving due antenatal care. [Int J Reprod Contracept Obstet Gynecol 2015; 4(6.000: 1891-1893

    2001-07-01

    This study was designed to investigate the effect of histaminergic agonists and antagonists on the acquisition of vestibular habituation. The experimental animals, pigeons, were subjected to unilateral rotatory and sway habituation training sessions. The habituation of postural reflexes and post-rotatory head nystagmus was assessed. Vestibular habituation in the control group was achieved by adopting the kinetic reflex posture after approximately 9 training sessions, and after 10 and 14 training sessions, respectively for 50% reduction of the total number of beats (TNB) and the duration of post-rotatory head nystagmus. In the sway adaptation test control pigeons needed nearly 15 training sessions while pigeons receiving betahistine adapted after approximately 8 sessions. Administration of histamine and, most notably, betahistine accelerated the process, while both H1 and H2 antagonists (clemastine, cimetidine) tended to retard it, indicating a less significant contribution of H2 receptors. The cholinergic agent physostigmine strongly retarded habituation while the anticholinergic agent scopolamine markedly accelerated it. In addition the adrenomimetic agent ephedrine also accelerated habituation while the adrenolytic agent droperidol retarded reduction of nystagmus beats. The results indicate that histaminergic receptors play a significant role in the vestibular habituation mechanism but are intricately involved with other types of receptors. Betahistine is clearly the agent of choice for attenuating vestibular effects.

  5. Abortion and contraceptive failure.

    Science.gov (United States)

    1998-01-01

    Persona, marketed by Unipath, is a new method of natural family planning which has been on the market since 1996. It works by measuring the hormone levels in a woman's urine and letting her know when she is not fertile and may have sex without using a barrier method of contraception. The British Pregnancy Advisory Service (BPAS) found that their surveyed clients who reported using Persona had 188 abortions in 3 months and concluded that there was a need for better information and more advice for couples who plan to use the method. The other major non-NHS abortion provider, Marie Stopes International, reported similar findings, with about 60 women per month visiting their clinics for abortions after having used the method. The BPAS survey also showed that 43% of the women who had an abortion after using Persona were aged 24 years or younger even though Persona is intended for use by women aged 25-40 years in stable relationships. A similar proportion also reported having sex on days when the method told them that they were most fertile. These latter women were not asked if they used another method of contraception on fertile days. An additional 13% reported ignoring the instructions to wait for 3 natural periods after terminating pill use before beginning to use Persona.

    Polish laws specify the parties responsible for lawful medical care in the availability of abortion differently than the Resolution of the Council of Europe. According to Polish regulations they include all Polish doctors while according to the Resolution, the state. Polish rules should not discriminate against anyone in connection with his religion or belief, even more so because the issue of abortion is an example of an unresolved ethical dispute. The number of lawful abortion in Poland does not exceed 1000 per year and can be carried out by only a few specialists contracted by the National Health Fund. Sufficient information and assistance should be provided to all pregnant women by the National Health Fund. The participation of all physicians in the informing process is not necessary, as evidenced by the lack of complaints to provide information on where in vitro fertilization treatment can be found - until recently only available when paid for by the individual and performed in much larger numbers than abortion. Entities performing this paid procedure made sure to provide information on their own. The rejection of the right to the conscientious objection clause by negating the right to refuse information may lead some to give up the profession or cause the termination of certain professionals on the basis of the professed worldview. Meanwhile, doctors are not allowed to be discriminated against on the basis of their conscience or religion.

    1993-01-01

    The Swedish abortion legislation of 1975 gave women the right to make a decision about abortion before the end of the 18th week of pregnancy. The number of abortions is rising in Sweden as a chosen method of birth control. The attitudes of students toward abortion were studied in 1986-1987. A questionnaire containing items on how sex education is taught, the anatomy and physiology of reproduction, contraceptives, sexually transmitted diseases, and legal abortion was answered by 421 high school students. Results pertaining to the students' attitudes toward abortion are reported. Two thirds of the students believed that the decision about an abortion should be made by the man and woman together. Nearly all respondents believed that abortion should not be considered a method of birth control. These results may be considered a guide for interventions to prevent the need for abortion. One fourth of all pregnancies in Sweden terminate in abortion. The students in the present study thought of abortion as a solution. Authors studying samples with different cultural backgrounds have reported similar attitudes.

    2008-01-01

    Habituation to frightening stimuli plays an important role in horse training. To investigate the extent to which horses generalise between different visual objects, 2-year-old stallions were habituated to feeding from a container placed inside a test arena and assigned as TEST (n = 12) or REFERENCE...... horses (n = 12). In Experiment 1, TEST horses were habituated to six objects (ball, barrel, board, box, cone, cylinder) presented in sequence in a balanced order. The objects were of similar size but different colour. Each object was placed 0.5 m in front of the feed container, forcing the horses to pass...... the object to get to the food. TEST horses received as many 2 min exposures to each object as required to meet a habituation criterion. We recorded behavioural reactions to the object, latency to feed, total eating time, and heart rate (HR) during all exposures. There was no significant decrease in initial...

  13. The consequences of abortion legislation.

    Science.gov (United States)

    Braude, M

    1983-01-01

    This article examines the consequences of the 1973 US Supreme Court decision legalizing abortion as well as potential implications of proposed legilation aimed at nullifying this decision. In addition to giving women the right to determine their own reproduction, legal abortion had had beneficial health effects for both mothers and infants. The partial reversal of abortion gains due to restrictions on public funding and limitations on how and where abortions can be performed has produced a slight increase in abortion mortality, but the impact has not been dramatic. Moreover, each year since 1973, women have been obtaining abortions earlier in pregnancy. Abortion may be experienced as a loss by the mother, but there is no evidence of serious psychological sequelae. In contrast, a large body of evidence supports the physical, psychological, and social benefits of legal abortion to women, children, and families. However, proponents of the proposed Human Life Amendment place protection of the rights of the fetus over all other considerations. Their antiabortion actions have challenged the medical tradition of privacy and the confidentiality of the doctor-patient relationship. Most supporters of legal abortion would prefer that there be fewer abortions; such a decrease is more likely as a result of better education and contraceptive methods rather than coercion.

    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.

  15. Experimental hemispherectomy and hemicerebellectomy and their influence on vestibular habituation.

    Kazmierczak, H; Pawlak-Osińska, K; Osiński, P

    1998-01-01

    The aim of the study was to estimate the influence of hemispherectomy and hemicerebellectomy on acquisition and retention of vestibular habituation in pigeons. The habituation training was performed using a rotatory test. The frequency of head nystagmus and postural reflexes was examined before and after acquisition of habituation and some days later, for the evaluation of the retention process. Our results suggested that the hemispherectomy did not inhibit the acquisition of habituation but retention of this phenomenon was shorter at that time. The hemicerebellectomy made it impossible to reveal the vestibular habituation.

    Across four decades of political and social action, Nepal changed from a country strongly enforcing oppressive abortion restrictions, causing many poor women's long imprisonment and high rates of abortion-related maternal mortality, into a modern democracy with a liberal abortion law. The medical and public health communities supported women's rights activists in invoking legal principles of equality and non-discrimination as a basis for change. Legislative reform of the criminal ban in 2002 and the adoption of an Interim Constitution recognizing women's reproductive rights as fundamental rights in 2007 inspired the Supreme Court in 2009 to rule that denial of women's access to abortion services because of poverty violated their constitutional rights. The government must now provide services under criteria for access without charge, and services must be decentralized to promote equitable access. A strong legal foundation now exists for progress in social justice to broaden abortion access and reduce abortion stigma.

  17. Abortion in a just society.

    Science.gov (United States)

    Hunt, M E

    1993-01-01

    A female Catholic theologian imagines a just society that does not judge women who decide to undergo an abortion. The Church, practitioners, and the courts must trust that women do make person-enhancing choices about the quality of life. In the last 15 years most progress in securing a woman's right to abortion has been limited to white, well-educated, and middle or upper middle class women. A just society would consider reproductive options a human right. Abortion providers are examples of a move to a just society; they are committed to women's well-being. There are some facts that make one pessimistic about achieving abortion in a just society. The US Supreme Court plans to review important decisions establishing abortion as a civil right. Further, some men insist on suing women who want to make their own reproductive decisions--an anti-choice tactic to wear away women's right to reproductive choice. Bombings of abortion clinics and harassment campaigns by anti-choice groups are common. These behaviors strain pro-choice proponents emotionally, psychically, and spiritually. Their tactics often lead to theologians practicing self-censorship because they fear backlash. Abortion providers also do this. Further, the reaction to AIDS is that sex is bad. Anti-abortion groups use AIDS to further their campaigns, claiming that AIDS is a punishment for sex. Strategies working towards abortion in a just society should be education and persuasion of policymakers and citizens about women's right to choose, since they are the ones most affected by abortion. Moreover, only women can secure their rights to abortion. In a just society, every health maintenance organization, insurance company, and group practice would consider abortion a normal service. A just society provides for the survival needs of the most marginalized.

  18. Psychiatric sequelae of induced abortion.

    Gibbons, M

    1984-03-01

    An attempt is made to identify and document the problems of comparative evaluation of the more recent studies of psychiatric morbidity after abortion and to determine the current consensus so that when the results of the joint RCGP/RCOG study of the sequelae of induced abortion become available they can be viewed in a more informed context. The legalization of abortion has provided more opportunities for studies of subsequent morbidity. New laws have contributed to the changing attitudes of society, and the increasing acceptability of the operation has probably influenced the occurrence of psychiatric sequelae. The complexity of measuring psychiatric sequelae is evident from the many terms used to describe symptomatology and behavioral patterns and from the number of assessment techniques involved. Numerous techniques have been used to quantify psychiatric sequelae. Several authors conclude that few psychiatric problems follow an induced abortion, but many studies were deficient in methodology, material, or length of follow-up. A British study in 1975 reported a favorable outcome for a "representative sample" of 50 National Health Service patients: 68% of these patients had an absence of or only mild feelings of guilt, loss, or self reproach and considered abortion as the best solution to their problem. The 32% who had an adverse outcome reported moderate to severe feelings of guilt, regret, loss, and self reproach, and there was evidence of mental illness. In most of these cases the adverse outcome was related to the patient's environment since the abortion. A follow-up study of 126 women, which compared the overall reaction to therapeutic abortion between women with a history of previous mild psychiatric illness and those without reported that a significantly different emotional reaction could not be demonstrated between the 2 groups. In a survey among women seeking an abortion 271 who were referred for a psychiatric opinion regarding terminations of pregnancy

    Full Text Available All schools of Islamic jurisprudence regard abortion as wrong and forbidden and allow abortion only before the stage of ensoulment, if the continuation of pregnancy would endanger the mother's life or put her into intolerable difficulties. In this article we describe and assess the viewpoint of Shiite jurisprudence toward abortion. "nUsing a selected collection of related references, and discussion describes with experts, this article the abortion in Shiite jurisprudence."nIn the Shiite jurisprudence, the ensoulment occurs after about 4 months. Before this stage, all Shiite authorities regard abortion as forbidden (Hiram unless if continuing the pregnancy would put the mother's life in real danger or will be intolerable for her. But after that, they regard abortion as Hiram, unless in conditions in which continuing the pregnancy results in dying of both mother and fetus, but abortion will save the life of mother. However, the Shiite authorities have not accepted to legitimate abortion in unwanted pregnancies and even in pregnancies resulted from adultery (Zina or rape."nThe debate over abortion is still controversial as ever. There are some important and notable related Fatwas that make jurisprudical basis for some new and problem solving legal acts, showing the inherent and valuable flexibility of the Shiite jurisprudence in dealing with such important issues. Some related issues, such as the priority of saving the life of mother after ensoulment can be referred to jurisprudical authorities for more assessment.

  2. Auditory habituation to simple tones: reduced evidence for habituation in children compared to adults

    2013-07-01

    Full Text Available Habituation – the response decrement to repetitively presented stimulation - is a basic cognitive capability and suited to investigate development and integrity of the human brain. To evaluate the developmental process of auditory habituation, the current study used magnetoencephalography to investigate auditory habituation, dishabituation and stimulus specificity in children and adults and compared the results between age groups. Twenty-nine children (Mage = 9.69 years, SD ± 0.47 and 14 adults (Mage = 29.29 years, SD ± 3.47 participated in the study and passively listened to a habituation paradigm consisting of 100 trains of tones which were composed of five 500Hz tones, one 750Hz tone (dishabituator and another two 500Hz tones, respectively while focusing their attention on a silent movie. Adults showed the expected habituation and stimulus specificity within-trains while no response decrement was found between trains. Sensory adaptation or fatigue as a source for response decrement in adults is unlikely due to the strong reaction to the dishabituator (stimulus specificity and strong mismatch negativity responses. However, in children neither habituation nor dishabituation or stimulus specificity could be found within-trains, response decrement was found across trains. It can be speculated that the differences between children and adults are linked to differences in stimulus processing due to attentional processes. This study shows developmental differences in task-related brain activation and discusses the possible influence of broader concepts such as attention, which should be taken into account when comparing performance in an identical task between age groups.

    Morgenthau, J E

    1984-01-01

    The issue of abortion, except when it is rendered moot because the fetus endangers the life of the mother, is not really a medical issue. The physician's role is to help patients achieve and maintain their maximum potential for physical, mental, and social well-being. To accomplish this, the physician must acquire a constantly evolving database of scientific knowledge, must evaluate this information in a critical and ethical manner, and must be prepared to apply what is learned. In the realm of applied ethics, no particular religion, profession, culture, class, or sex should be thought of as having all the answers in the realm of applied ethics. This physician's actions are predicated on the belief that, to a large extent, ethical precepts reflect the broader social and economic issues of the period in which they are articulated. If this is the case, then in today's world the population explosion, the postindustrial society, the women's rights movement, inequality of access, and the ability to perform prenatal diagnosis are all factors which have molded the approach to the issue of abortion. Only the last 3 of these can in any way be considered as medical. When considering the role of a physician in dealing with the issue of abortion in the adolescent, this individual relies on the concept articulated by the World Health Association (WHA): promoting the physical, emotional, and social well-being of one's patients. Each year in the US over 1 million 15-19 year olds become pregnant, resulting in over 600,000 births. Most of these pregnancies are unintentional, yet approximately 90% of the infants are kept in the home by mothers who are ill prepared to be parents. What is most disturbing is that the pregnancy rate for the younger mother, 16 years or under, is accounting for an ever increasing percentage of the total. Studies at the Adolescent Health Center of the Mount Sinai Hospital in New York City as well as national studies suggest that the younger teens are more

  7. Reducing abortion: the Danish experience.

    Science.gov (United States)

    Risor, H

    1989-01-01

    In 1987, 20,830 legal abortions were performed in Denmark. 2,845 involved women below the age of 20, and 532 involved women terminating pregnancy after the 12th week. Danish law permits all of its female citizens to have an abortion free-of-charge before the 12th week of pregnancy. After the 12th week, the abortion must be applied for through a committee of 3 members, and all counties in Denmark have a committee. It is felt in Denmark that a woman has a right to an abortion if she decides to have one. It she makes that choice, doctors and nurses are supportive. Since 1970, sex education has been mandatory in Danish schools. Teachers often collaborate closely with school doctors and nurses in this education. All counties are required to have at least 1 clinic that provides contraceptive counselling. It was recently found that the lowest number of pregnancies among teenaged girls was found in a county in Jutland where all 9th grade students visit the county clinic to learn about contraceptives, pregnancy, and abortion. Within 1 year after Copenhagen had adopted this practice, the number of abortions among teenagers declined by 20%. One fourth of all pharmacies also collaborate with schools to promote sex education, instructing students about contraceptives and pregnancy tests. The Danish Family Planning Association has produced a film on abortion, and plans to produce videos on abortion for use in schools. The organization also holds training programs for health care personnel on contraception, pregnancy, and abortion. By means of the practices described above, it is hoped that the number of abortions and unwanted pregnancies in Denmark will be reduced.

  8. Temporomandibular disorders: the habitual chewing side syndrome.

    Directory of Open Access Journals (Sweden)

    Urbano Santana-Mora

    Full Text Available BACKGROUND: Temporomandibular disorders are the most common cause of chronic orofacial pain, but, except where they occur subsequent to trauma, their cause remains unknown. This cross-sectional study assessed chewing function (habitual chewing side and the differences of the chewing side and condylar path and lateral anterior guidance angles in participants with chronic unilateral temporomandibular disorder. This is the preliminary report of a randomized trial that aimed to test the effect of a new occlusal adjustment therapy. METHODS: The masticatory function of 21 randomly selected completely dentate participants with chronic temporomandibular disorders (all but one with unilateral symptoms was assessed by observing them eat almonds, inspecting the lateral horizontal movement of the jaw, with kinesiography, and by means of interview. The condylar path in the sagittal plane and the lateral anterior guidance angles with respect to the Frankfort horizontal plane in the frontal plane were measured on both sides in each individual. RESULTS: Sixteen of 20 participants with unilateral symptoms chewed on the affected side; the concordance (Fisher's exact test, P = .003 and the concordance-symmetry level (Kappa coefficient κ = 0.689; 95% confidence interval [CI], 0.38 to 0.99; P = .002 were significant. The mean condylar path angle was steeper (53.47(10.88 degrees versus 46.16(7.25 degrees; P = .001, and the mean lateral anterior guidance angle was flatter (41.63(13.35 degrees versus 48.32(9.53 degrees P = .036 on the symptomatic side. DISCUSSION: The results of this study support the use of a new term based on etiology, "habitual chewing side syndrome", instead of the nonspecific symptom-based "temporomandibular joint disorders"; this denomination is characterized in adults by a steeper condylar path, flatter lateral anterior guidance, and habitual chewing on the symptomatic side.

    Habituation is a common form of non-associative learning in which the organism gradually decreases its response to repeated stimuli. The decrease in exploratory activity of many animal species during exposure to a novel open field arena is a widely studied habituation paradigm. However, a theoretical framework to quantify how the novelty of the arena is learned during habituation is currently missing. Drosophila melanogaster display a high mean absolute activity and a high probability for dir...

  10. The Habituation/Cross-Habituation Test Revisited: Guidance from Sniffing and Video Tracking

    Directory of Open Access Journals (Sweden)

    G. Coronas-Samano

    2016-01-01

    Full Text Available The habituation/cross-habituation test (HaXha is a spontaneous odor discrimination task that has been used for many decades to evaluate olfactory function in animals. Animals are presented repeatedly with the same odorant after which a new odorant is introduced. The time the animal explores the odor object is measured. An animal is considered to cross-habituate during the novel stimulus trial when the exploration time is higher than the prior trial and indicates the degree of olfactory patency. On the other hand, habituation across the repeated trials involves decreased exploration time and is related to memory patency, especially at long intervals. Classically exploration is timed using a stopwatch when the animal is within 2 cm of the object and aimed toward it. These criteria are intuitive, but it is unclear how they relate to olfactory exploration, that is, sniffing. We used video tracking combined with plethysmography to improve accuracy, avoid observer bias, and propose more robust criteria for exploratory scoring when sniff measures are not available. We also demonstrate that sniff rate combined with proximity is the most direct measure of odorant exploration and provide a robust and sensitive criterion.

While abortion is illegal in Ireland, the Supreme Court directed in 1992 that Irish women can go to Britain for abortions when their lives are thought to be at risk. Abortion was a constant feature during the Irish Presidential election campaign in October, while a dispute about the future of a 13-year-old girl's pregnancy dominated the headlines in November. The presidential election on October 30 resulted in a victory for one of the two openly anti-choice candidates, Mary McAleese, a lawyer from Northern Ireland. With a voter turnout of 47.6%, McAleese polled 45.2% of the votes cast. Although the president may refuse to sign bills which have been passed by parliament, McAleese has said that she will sign whatever bill is placed before her, even if it liberalizes abortion law in the republic. As for the case of the 13-year-old pregnant girl, she was taken into the care of Irish health authority officials once the case was reported to the police. However, the health board, as a state agency, is prevented by Irish law from helping anyone travel abroad for abortion. The girl was eventually given leave in a judgement by a High Court Judicial Review on November 28 to travel to England for an abortion.

    1997-09-01

    The Cardinal of Milan and the linguist and writer Umberto Eco maintained a correspondence in the mid-1990s in connection with the Italian magazine ¿Liberal¿. One of the issues discussed was the conflict between belief in the value of human life and existing abortion legislation. Umberto Eco stated that he would do all in his power to dissuade a woman pregnant with his child from having an abortion, regardless of the personal cost to the parents, because the birth of a child is a miracle. He would not, however, feel capable of imposing his ethical position on anyone else. Terrible moments occur in which women have a right to make autonomous decisions concerning their bodies, their feelings, their futures. Those who disagree cite the right to life, a rather vague concept about which even atheists can be enthusiastic. The moment at which a new human being is formed has been brought to the center of Catholic theology, despite its uncertainty; the beginning of a new life may always need to be understood as a process whose end result is the newborn. Only the mother should decide at what moment the process may be interrupted. The cardinal¿s response distinguished between psychic and physical life, on the one hand, and life participating in the life of God on the other. The threshold is the moment of conception, reflecting a continuity of identity. The new being is worthy of respect. Any violation of the affection and care owed to the being can only be experienced as a profound suffering and painful laceration that may never heal. The response of Eco is unknown.

    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.

    2005-07-01

    Complications of induced abortion sadly remain significant causes of maternal mortality and morbidity around the world, but only in countries that do not provide access to safe abortion services. This article presents a brief account of how high maternal mortality from induced abortion became history in the UK and the dire consequences to women's health that unsafe abortion still has in many countries of the world. It gives a brief overview of the methods available to evacuate the uterus, with particular reference to manual vacuum aspiration. The status of the law in different countries is discussed, together with the need for health professionals to interpret repressive laws in ways that enables them to care for women who seek their help. Safe abortion services are cost effective, essential services for women. Men are part and parcel of the reason women resort to terminating a pregnancy, and, together with the countless children whose lives are dependent on a healthy caring mother, are also beneficiaries of safe abortion services. There can be no excuse for continuing to deny these services to so many women around the world.

  1. Contraception and abortion in Romania.

    Johnson, B R; Horga, M; Andronache, L

    1993-04-03

    After the downfall of the Ceausescu regime in December, 1989, the new Government of Romania abolished the law that prohibited abortions on request. Subsequently, the rate of legally induced abortions increased significantly while the rate of maternal mortality declined dramatically. Despite the large number of women who request induced abortions, most women and gynaecologists say that they would prefer to prevent unwanted pregnancies through the use of modern contraception. In this paper we examine factors that contribute to the disparity between women's desire to use modern contraception to prevent unwanted pregnancies and their practice of having induced abortions to prevent unwanted births. The results show that women (and suggest that men) need a wide choice of dependably available high-quality contraceptives; they need to be able to obtain information, counselling, and methods from a wide range of sources/health-care providers; both women's and men's perceptions about, and use of, modern contraception could be positively affected through sexual education started in secondary school; and, to reduce repeat abortions, women's post-abortion family-planning needs must not be neglected.

  2. Habitual physical activity in mitochondrial disease.

    Directory of Open Access Journals (Sweden)

    Shehnaz Apabhai

    Full Text Available PURPOSE: Mitochondrial disease is the most common neuromuscular disease and has a profound impact upon daily life, disease and longevity. Exercise therapy has been shown to improve mitochondrial function in patients with mitochondrial disease. However, no information exists about the level of habitual physical activity of people with mitochondrial disease and its relationship with clinical phenotype. METHODS: Habitual physical activity, genotype and clinical presentations were assessed in 100 patients with mitochondrial disease. Comparisons were made with a control group individually matched by age, gender and BMI. RESULTS: Patients with mitochondrial disease had significantly lower levels of physical activity in comparison to matched people without mitochondrial disease (steps/day; 6883±3944 vs. 9924±4088, p = 0.001. 78% of the mitochondrial disease cohort did not achieve 10,000 steps per day and 48% were classified as overweight or obese. Mitochondrial disease was associated with less breaks in sedentary activity (Sedentary to Active Transitions, % per day; 13±0.03 vs. 14±0.03, p = 0.001 and an increase in sedentary bout duration (bout lengths/fraction of total sedentary time; 0.206±0.044 vs. 0.187±0.026, p = 0.001. After adjusting for covariates, higher physical activity was moderately associated with lower clinical disease burden (steps/day; r(s = -0.49; 95% CI -0.33, -0.63, P<0.01. There were no systematic differences in physical activity between different genotypes mitochondrial disease. CONCLUSIONS: These results demonstrate for the first time that low levels of physical activity are prominent in mitochondrial disease. Combined with a high prevalence of obesity, physical activity may constitute a significant and potentially modifiable risk factor in mitochondrial disease.

  3. Virtue theory and abortion.

    Science.gov (United States)

    Hursthouse, Rosalind

    1991-01-01

    The sort of ethical theory derived from Aristotle, variously described as virtue ethics, virtue-based ethics, or neo-Aristotelianism, is becoming better known, and is now quite widely recognized as at least a possible rival to deontological and utilitarian theories. With recognition has come criticism, of varying quality. In this article I shall discuss nine separate criticisms that I have frequently encountered, most of which seem to me to betray an inadequate grasp either of the structure of virtue theory or of what would be involved in thinking about a real moral issue in its terms. In the first half I aim particularly to secure an understanding that will reveal that many of these criticisms are simply misplaced, and to articulate what I take to be the major criticism of virtue theory. I reject this criticism, but do not claim that it is necessarily misplaced. In the second half I aim to deepen that understanding and highlight the issues raised by the criticisms by illustrating what the theory looks like when it is applied to a particular issue, in this case, abortion.

  4. Habituation and prepulse inhibition of acoustic startle in rodents.

    Science.gov (United States)

    Valsamis, Bridget; Schmid, Susanne

    2011-09-01

    The acoustic startle response is a protective response, elicited by a sudden and intense acoustic stimulus. Facial and skeletal muscles are activated within a few milliseconds, leading to a whole body flinch in rodents(1). Although startle responses are reflexive responses that can be reliably elicited, they are not stereotypic. They can be modulated by emotions such as fear (fear potentiated startle) and joy (joy attenuated startle), by non-associative learning processes such as habituation and sensitization, and by other sensory stimuli through sensory gating processes (prepulse inhibition), turning startle responses into an excellent tool for assessing emotions, learning, and sensory gating, for review see( 2, 3). The primary pathway mediating startle responses is very short and well described, qualifying startle also as an excellent model for studying the underlying mechanisms for behavioural plasticity on a cellular/molecular level(3). We here describe a method for assessing short-term habituation, long-term habituation and prepulse inhibition of acoustic startle responses in rodents. Habituation describes the decrease of the startle response magnitude upon repeated presentation of the same stimulus. Habituation within a testing session is called short-term habituation (STH) and is reversible upon a period of several minutes without stimulation. Habituation between testing sessions is called long-term habituation (LTH)(4). Habituation is stimulus specific(5). Prepulse inhibition is the attenuation of a startle response by a preceding non-startling sensory stimulus(6). The interval between prepulse and startle stimulus can vary from 6 to up to 2000 ms. The prepulse can be any modality, however, acoustic prepulses are the most commonly used. Habituation is a form of non-associative learning. It can also be viewed as a form of sensory filtering, since it reduces the organisms' response to a non-threatening stimulus. Prepulse inhibition (PPI) was originally

  5. [Readers' position against induced abortion].

    Science.gov (United States)

    1981-08-25

    Replies to the request by the Journal of Nursing on readers' positions against induced abortion indicate there is a definite personal position against induced abortion and the assistance in this procedure. Some writers expressed an emotional "no" against induced abortion. Many quoted arguments from the literature, such as a medical dictionary definition as "a premeditated criminally induced abortion." The largest group of writers quoted from the Bible, the tenor always being: "God made man, he made us with his hands; we have no right to make the decision." People with other philosophies also objected. Theosophical viewpoint considers reincarnation and the law of cause and effect (karma). This philosophy holds that induced abortion impedes the appearance of a reincarnated being. The fundamental question in the abortion problem is, "can the fetus be considered a human life?" The German anatomist Professor E. Bleckschmidt points out that from conception there is human life, hence the fertilized cell can only develop into a human being and is not merely a piece of tissue. Professional nursing interpretation is that nursing action directed towards killing of a human being (unborn child) is against the nature and the essence of the nursing profession. A different opinion states that a nurse cares for patients who have decided for the operation. The nurse doesn't judge but respects the individual's decision. Some proabortion viewpoints considered the endangering of the mother's life by the unborn child, and the case of rape. With the arguments against abortion the question arises how to help the woman with unwanted pregnancy. Psychological counseling is emphasized as well as responsible and careful assistance. Referral to the Society for Protection of the Unborn Child (VBOK) is considered as well as other agencies. Further reader comments on this subject are solicited.

  6. Polish parliament liberalizes abortion law.

    Science.gov (United States)

    1996-11-22

    On October 24, the Sejm (Poland's lower house of parliament) voted 228 to 195 (with 16 abstentions) to amend Poland's March 1993 ban on abortions. The amendment legalizes abortion until the 12th week of pregnancy for women who face financial hardship or difficult personal circumstances. Client counseling by a doctor who will not perform the abortion and a 3-day wait are required. Abortions will be permitted in licensed private clinics, as well as in public hospitals. Anyone performing an illegal abortion can receive 2 years' imprisonment. The government will subsidize contraceptive pills, and a sex education curriculum will be developed for schools. Abortion had been legal and widely available under communist rule; however, a Catholic-aligned government limited abortion to cases where a woman's life or health was endangered, where the pregnancy resulted from rape or incest, or where the fetus had a severe anomaly. The Catholic Church opposed the new measure, and the Senat (Poland's upper house), on October 3, had voted 40 to 52 (with 2 abstentions) against the amendment. Although the Sejm had previously voted 208 to 61 (with 15 abstentions) in favor of the amendment, 120 of those opposed to the measure, primarily members of the Polish Peasants Party (part of Poland's ruling coalition), had walked out in protest just before an August tally. The Democratic Left Alliance, the other coalition partner, supports the amendment. The most recent vote in the Sejm overturns the Senat veto; however, before the law can go into effect in 1997, it must be signed by President Aleksandr Kwasniewski (a supporter) after a review by Poland's conservative constitutional tribunal.

    Pooled literatures showed that the induced abortion in China faces many problems:the number of induced abortion remains large; most cases are young and nulliparity women; the frequency of abortion is high; and the interval between one and another abortion is short. Health promotion strategies should be applied to address these problems. It is important to increase the population's awareness of contraception,especially among nulliparity and migrant populations. Routine and effective contraceptive methods should be recommended and emphasized during induced abortion and delivery to lower the rate of induced abortion.

  8. Testing the habituation assumption underlying models of parasitoid foraging behavior

    Science.gov (United States)

    Abram, Katrina; Colazza, Stefano; Peri, Ezio

    2017-01-01

    Background Habituation, a form of non-associative learning, has several well-defined characteristics that apply to a wide range of physiological and behavioral responses in many organisms. In classic patch time allocation models, habituation is considered to be a major mechanistic component of parasitoid behavioral strategies. However, parasitoid behavioral responses to host cues have not previously been tested for the known, specific characteristics of habituation. Methods In the laboratory, we tested whether the foraging behavior of the egg parasitoid Trissolcus basalis shows specific characteristics of habituation in response to consecutive encounters with patches of host (Nezara viridula) chemical contact cues (footprints), in particular: (i) a training interval-dependent decline in response intensity, and (ii) a training interval-dependent recovery of the response. Results As would be expected of a habituated response, wasps trained at higher frequencies decreased their behavioral response to host footprints more quickly and to a greater degree than those trained at low frequencies, and subsequently showed a more rapid, although partial, recovery of their behavioral response to host footprints. This putative habituation learning could not be blocked by cold anesthesia, ingestion of an ATPase inhibitor, or ingestion of a protein synthesis inhibitor. Discussion Our study provides support for the assumption that diminishing responses of parasitoids to chemical indicators of host presence constitutes habituation as opposed to sensory fatigue, and provides a preliminary basis for exploring the underlying mechanisms.

  9. Habituation of LG-mediated tailflip in the crayfish.

    Science.gov (United States)

    Nagayama, Toshiki; Araki, Makoto

    2015-06-01

    Crayfish escape from threatening stimuli by tailflipping. If a stimulus is applied to the rear, crayfish escape up and forwards in a summersault maneuver that is mediated by the activation of lateral giant (LG) interneurons. The occurrence probability of LG-mediated tailflip, however, diminishes and habituates if a stimulus is repeatedly applied. Since crayfish have a relatively simple CNS with many identifiable neurons, crayfish represent a good animal to analyze the cellular basis of habituation. A reduction in the amplitude of the EPSP in the LGs, caused by direct chemical synaptic connection from sensory afferents by repetitive stimulations, is essential to bring about an inactivation of the LGs. The spike response of the LGs recovers within several minutes of habituation, but the LGs subsequently fail to spike when an additional stimulus is applied after specific periods following habituation. These results indicate that a decline in synaptic efficacy from the mechanosensory afferents recovers readily after a short delay, but then the excitability of the LGs themselves decreases. Furthermore, the processes underlying habituation are modulated depending on a social status. When two crayfish encounter each other, a winner-loser relationship is established. With a short interstimulus interval of 5 s, the rate of habituation of the LG in both socially dominant and subordinate crayfish becomes lower than in socially isolated animals. Serotonin and octopamine affect this social status-dependent modulation of habituation by means of activation of downstream second messenger system of cAMP and IP3 cascades, respectively.

    1973-03-01

    The article reports upon the characteristics of 300 abortion applicants in Arkansas manifesting significant stress from unwanted pregnancy between May 1, 1970 and June 30, 1971. The sample is limited by the fact that all of these women had been willing to seek medical aid. Patients ranged from ages 13-47, 131 of them ages 17-21. 35% had had some college education; another 29% were high school graduates. 50.6%, 20.6%, and 27.3% were single, divorced, and married, respectively. 59.6% of the patients were primiparas. 18.3%, 9.6%, and 12.3% were classified as being neurotic, having psychophysiologic tendencies (gastrointestinal problems, obesity, chronic headaches), and having sociopathic features (passive-aggressive, frankly rebellious, delinquent, antisocial, alcoholic), respectively. 12 women had noticeable schizoid features; 4 women had mildly active schizophrenia. Fathers of the women were usually blue-collar workers (55.3%) or white-collar workers (24.6%). The most frequent ordinal sibling position among the women was oldest child (38%). Parental instability (1 or both parents lost through death, divorce, father usually away working, chronic alcoholism, etc.) was reported by 39.6% of the patients. Patients' attitudes toward the unwanted pregnancy included dislike of inexpediency of the situation (82.6%), self-depreciation (55.6%), and aversion (28.6%). Precipitated psychiatric disorders were for the greatest part mild. Manifesting symptoms included depression (66.7%), anxiety (21%), and mixed anxiety and depression (12.2%). Suicidal threats and gestures were made by 22 and 8 patients, respectively. In summary, the study reveals a group of predominantly Caucasian women from unstable, middle-class urban families who were going through an adjustment reaction to adolescence or adult life.

  11. Abortion and the law: the Supreme Court, privacy, and abortion.

    Science.gov (United States)

    Marsh, F H

    1997-01-01

    This article examines the impact of the continuing politicization of the abortion issue in the US on the rights of women and on the emerging concept of fetal rights. The introduction 1) attributes the "final and total politicization" of a woman's right to control her reproduction to the "undue burden" standard introduced by the Supreme Court in its 1992 Casey decision and 2) claims that, if unchecked, the concept of fetal rights may give the state's interest in protecting potential life supremacy over women's rights. The next section presents an in-depth discussion of the politicization of the right to abortion that covers such topics as how the courts before Casey became the forum for debating abortion policy, how the "undue burden" standard fails to set definite parameters of acceptable state behavior, how the Casey decision in effect abandons the trimester-based framework of reference provided in Roe vs. Wade, how Casey allows states to subtly coerce women seeking abortions, how the Casey decision failed to reduce the intense politicization of abortion, and how the court failed to protect individual rights to health care and abortion funding from states. Part 3 of the article begins its exploration of the concept of "fetal rights" with a sketch of the history of this concept in the US courts starting in 1884 when damages for miscarriage were denied. Ways in which fetal rights compete with the rights of a pregnant woman are described, the Supreme Court is blamed for allowing states to develop this concept, and issues of patient confidentiality versus reporting requirements are considered. It is concluded that the Supreme Court will have to act to limit fetal rights.

  12. Global consequences of unsafe abortion.

    Singh, Susheela

    2010-11-01

    Unsafe abortion is a significant cause of death and ill health in women in the developing world. A substantial body of research on these consequences exists, although studies are of variable quality. However, unsafe abortion has a number of other significant consequences that are much less widely recognized. These include the economic consequences, the immediate costs of providing medical care for abortion-related complications, the costs of medical care for longer-term health consequences, lost productivity to the country, the impact on families and the community, and the social consequences that affect women and families. This article will review the scientific evidence on the consequences of unsafe abortion, highlight gaps in the evidence base, suggest areas where future research efforts are needed, and speculate on the future situation regarding consequences and evidence over the next 5-10 years. The information provided is useful and timely given the current heightened interest in the issue of unsafe abortion, growing from the recent focus of national and international agencies on reducing maternal mortality by 75% by 2015 (as one of the Millennium Development Goals established in 2000).

  13. Abortion laws into action: implementing legal reform.

    Science.gov (United States)

    Gerhardt, A J

    1997-01-01

    The worldwide trend towards liberalizing abortion laws has resulted in reduced abortion-related mortality in areas where legal abortion is accessible. In countries considering abortion reform, policy-makers and health care providers have a responsibility to ensure that provisions of any new law can be met. Preparations underway to prepare for South Africa's new abortion law can serve as a guideline for such action. A new abortion law calls for policy changes that may include 1) developing new standards, protocols, and guidelines for abortion care services; 2) ensuring provision of adequate trained staff willing to provide abortions; 3) streamlining administrative regulations to avoid delays; 4) establishing regulations and mechanisms for drug and equipment supply and distribution; 5) restructuring the health system to accommodate provision of abortion services; 6) allocating funds for new abortion services; and 7) reviewing and revising security measures. In addition, health professionals will require training in abortion provision, staff will need information updates about aspects of the legislation, and administrators and providers in a position to impede provision of services must be made aware of the affect of unsafe abortion on maternal health. Researchers should document the effect of the new law on women's health, the provision of reproductive health services, and the community. IEC (information, education, communication) activities will be required to inform the public about the new law and services, establish sex education programs in schools and health facilities, and mobilize family planning organizations and programs to help reduce the incidence of repeat abortions.

    Science.gov (United States)

    1991-02-01

    Abortion is not a medical issue, as the law would like to make it when requesting definitions of when life begins. To medicine, life begins at conception. conception is the 1st step in the miracle of life. It is up to the law and society to determine when life begins legally. Doctors have responsibilities as citizens to do what they can to support laws they believe in. The American Medical Association has remained neutral on the issue. Abortion can be ethical if the mother's life is threatened. But it is unethical and unconstitutional when it is done out of convenience to correct indiscretions.

    1984-04-01

    The relationship of locus of control to deciding on an abortion was investigated by administering Rotter's Locus of Control Scale to 118 women immediately prior to abortion and 2 weeks and 3 months following abortion. Subjects' scores were compared across the 3 time periods, and the abortion group's pretest scores were compared with those of a nonpregnant control, group. As hypothesized, the aborting group scored significantly more internal than the general population but no differences in locus of control were found across the 3 time period. The length of delay in deciding to abort an unwanted pregnancy following confirmation was also assessed. Women seeking 1st trimester abortions were divided into internal and external groups on the Rotter Scale and the lengths of delay were compared. The hypothesis that external scores would delay the decision longer than internal ones was confirmed. The results confirm characteristics of the locus of control construct and add information about personality characteristics of women undergoing abortion.

    In 'After-birth abortion: why should the baby live?', Giubilini and Minerva argue that infanticide should be permitted for the same reasons as abortion. In particular, they argue that infanticide should be permitted even for reasons that do not primarily serve the interests (or would-be best interests) of the newborn. They claim that abortion is permissible for reasons that do not primarily serve the interests (or would-be interests) of the fetus because fetuses lack a right to life. They argue that newborns also lack a right to life, and they conclude that therefore, the same reasons that justify abortion can justify infanticide. This conclusion does not follow. The lack of a right to life is not decisive. Furthermore, the justificatory power of a given reason is a function of moral context. Generalisations about reasons across dissimilar moral contexts are invalid. However, a similar conclusion does follow-that fetus-killing and newborn-killing are morally identical in identical moral contexts-but this conclusion is trivial, since fetuses and newborns are never in identical moral contexts.

  4. [The influence of experimental hemispherectomy and hemicerebellectomy on the acquisition and retention of habituation in pigeon].

    The subject of investigation was the analysis of the acquisition and retention of the vestibular habituation in pigeons after hemispherectomy or hemicerebellectomy. The habituation training was performed using rotatory test. The frequency of head nystagmus and postural reflexes were examined before and after acquisition of habituation and some days later, for evaluation of retention. Our results suggests that hemispherectomy does not inhibit acquisition of habituation but retention of this phenomenon is shorter at that time. The hemicerebellectomy makes impossible the vestibular habituation.

  5. Free abortion has come to stay.

    In Sweden abortion has been free and on demand since 1975. The philosophy behind this law is that the pregnant women is the best judge of whether she should have an abortion. Any attempt to change the legal status of abortion should be strongly fought. Criminalizing abortion has never amounted to any good in any country that has tried it. A critical aspect of abortion is that it must be prevented with effective sexual education and free access to contraception. This is the best way to avoid unwanted pregnancies and thus abortion. Still even in Sweden 25% of all pregnancies end in abortion. Planned parenthood is essential in a country with a high standard of living in order to maintain an adequate level of births. Many countries with high standards of living have very low births rates because they do not offer parental leave, short working hours, or day care.

  6. Mental health and abortion: review and analysis.

    Ney, P G; Wickett, A R

    1989-11-01

    This survey of studies which relate to the emotional sequelae of induced abortion, draws attention to the need for more long-term, in-depth prospective studies. The literature to this point finds no psychiatric indications for abortion, and no satisfactory evidence that abortion improves the psychological state of those not mentally ill; abortion is contra-indicated when psychiatric disease is present, as mental ill-health has been shown to be worsened by abortion. Recent studies are turning up an alarming rate of post-abortion complications such as P.I.D., and subsequent infertility. The emotional impact of these complications needs to be studied. Other considerations looked at are the long-term demographic implications of abortion on demand and the effect on the medical professions.

  7. Abortion--the breath of life.

    Science.gov (United States)

    Joling, R J

    1974-01-01

    A scholarly review of medical-legal and biblical authority on the su bject of abortion supports abortion as a woman's right when it is performed before the fetus has had its "breath of life." Based on biblical evidence, a person becomes a living being when the soul, the "breath of life" is breathed into it. Without the "breath of life" no person exists. A fetus less than 28 weeks old is incapable of breathing alone; thus an aborted fetus that age is not truly a living human being capable of surviving independently of its mother's womb. Legal aspects include supreme, local and state court decisions defining abortion. It is ultimately expected that each person will determine what approach to take towards the abortion question. Abortion is still a personal problem regardless of supreme court decisions or ecclesiastical determinants. Religion and moral concepts should be the guiding conscience involved in the question of abortion.

  8. Induced abortion--a global health problem.

    Every year around 500,000 women are estimated to die from pregnancy-related causes, the majority in the developing world and many as a consequence of unsafe abortion. Around 25 per cent of maternal deaths in Asia and 30-50 per cent of maternal deaths in Africa and Latin America occur as a result of induced abortion. Data on abortion related maternal morbidity is less reliable than mortality but suggests that for every maternal death 10-15 women suffer significant pregnancy-related morbidity, i.e. infertility, genito-urinary problems and/or chronic pain. Induced abortion occurs in practically every society in the world but only 40 per cent of the women in the world live in countries where abortion is legally free. A permissive legislation is an important prerequisite for medically safe and early abortion. Oppositely, with a restrictive law, abortion is difficult to obtain, costly and possibly unsafe, in particular to the least affluent women in the society. Induced abortion in a developed country with legal and easy access to services is a safe procedure with hardly any mortality and very low morbidity. The best strategy to reduce the number of unsafe abortions is prevention of unwanted pregnancy. The consequences of unsafe abortion on women's health need to be acknowledged by everybody in the society in order to improve abortion care. It is necessary to adjust legal and other barriers to medically safe abortion in order to follow the declaration at the UN conference on population in Cairo, 1994, which stated that abortion, wherever legal, should be safe. It is also necessary to introduce preventive measures where abortions are performed, i.e. good and easily accessible family planning services.

  9. Induced abortion and contraception in Italy.

    Spinelli, A; Grandolfo, M E

    1991-09-01

    This article discusses the legal and epidemiologic status of abortion in Italy, and its relationship to fertility and contraception. Enacted in May 1978, Italy's abortion law allows the operation to be performed during the 1st 90 days of gestation for a broad range of health, social, and psychological reasons. Women under 18 must receive written permission from a parent, guardian, or judge in order to undergo an abortion. The operation is free of charge. Health workers who object to abortion because of religious or moral reasons are exempt from participating. Regional differences exist concerning the availability of abortion, easy to procure in some places and difficult to obtain in others. After an initial increase following legalization, the abortion rate was 13.5/1000 women aged 15-44 and the abortion ratio was 309/1000 live births -- an intermediate rate and ratio compared to other countries. By the time the Abortion Act of 1978 was adopted, Italy already had one of the lowest fertility levels in Europe. Thus, the legalization of abortion has had no impact on fertility trends. Contrary to initial fears that the legalization of abortion would make abortion a method of family planning, 80% of the women who sought an abortion in 1983-88 were using birth control at the time (withdrawal being the most common method used by this group). In fact, most women who undergo abortions are married, between the ages of 25-34, and with at least one child. Evidence indicates widespread ignorance concerning reproduction. In a 1989 survey, only 65% of women could identify the fertile period of the menstrual cycle. Italy has no sex education in schools or national family planning programs. Compared to most of Europe, Italy still has low levels of reliable contraceptive usage. This points to the need to guarantee the availability of abortion.

  10. Predator-Resembling Aversive Conditioning for Managing Habituated Wildlife

    2005-06-01

    Full Text Available Wildlife habituation near urban centers can disrupt natural ecological processes, destroy habitat, and threaten public safety. Consequently, management of habituated animals is typically invasive and often includes translocation of these animals to remote areas and sometimes even their destruction. Techniques to prevent or reverse habituation and other forms of in situ management are necessary to balance ecological and social requirements, but they have received very little experimental attention to date. This study compared the efficacy of two aversive conditioning treatments that used either humans or dogs to create sequences resembling chases by predators, which, along with a control category, were repeatedly and individually applied to 24 moderately habituated, radio-collared elk in Banff National Park during the winter of 2001-2002. Three response variables were measured before and after treatment. Relative to untreated animals, the distance at which elk fled from approaching humans, i.e., the flight response distance, increased following both human and dog treatments, but there was no difference between the two treatments. The proportion of time spent in vigilance postures decreased for all treatment groups, without differences among groups, suggesting that this behavior responded mainly to seasonal effects. The average distance between elk locations and the town boundary, measured once daily by telemetry, significantly increased for human-conditioned elk. One of the co-variates we measured, wolf activity, exerted counteracting effects on conditioning effects; flight response distances and proximity to the town site were both lower when wolf activity was high. This research demonstrates that it is possible to temporarily modify aspects of the behavior of moderately habituated elk using aversive conditioning, suggests a method for reducing habituation in the first place, and provides a solution for Banff and other jurisdictions to manage

    In young healthy subjects, initially large stretch responses in leg muscles are progressively attenuated following a series of identical postural perturbations. We have studied whether this habituation of stretch responses is impaired in Parkinson's disease. Ten patients and 10 elderly controls received 10 serial 'toe-up' rotational perturbations (amplitude 10 degrees) while standing on a supporting forceplate. We recorded posturally destabilizing medium latency (ML) stretch responses from the medial gastrocnemius muscle. Functional habituation across the first few trials occurred in patients, but not in elderly controls. The rate of habituation was influenced by the size of the response to the first perturbation. This observation explained the absence of habituation in elderly subjects because their responses during the first few trials were much smaller compared to patients. These results suggest that habituation of lower leg stretch responses is unimpaired in Parkinson's disease. The presence of initially large and 'unpracticed' responses may partially explain why Parkinson patients fall in response to unexpected postural disturbances that commonly occur in daily life.

  12. Sensory habituation of auditory receptor neurons: implications for sound localization.

    Givois, V; Pollack, G S

    2000-09-01

    Auditory receptor neurons exhibit sensory habituation; their responses decline with repeated stimulation. We studied the effects of sensory habituation on the neural encoding of sound localization cues using crickets as a model system. In crickets, Teleogryllus oceanicus, sound localization is based on binaural comparison of stimulus intensity. There are two potential codes at the receptor-neuron level for interaural intensity difference: interaural difference in response strength, i.e. spike rate and/or count, and interaural difference in response latency. These are affected differently by sensory habituation. When crickets are stimulated with cricket-song-like trains of sound pulses, response strength declines for successive pulses in the train, and the decrease becomes more pronounced as the stimulus intensity increases. Response decrement is thus greater for receptors serving the ear ipsilateral to the sound source, where intensity is higher, resulting in a decrease in the interaural difference in response strength. Sensory habituation also affects response latency, which increases for responses to successive sound pulses in the stimulus train. The change in latency is independent of intensity, and thus is similar for receptors serving both ears. As a result, interaural latency difference is unaffected by sensory habituation and may be a more reliable cue for sound localization.

  13. Is Induced Abortion Really Declining in Armenia?

    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.

    Work funded on this grant has explored the mechanisms of long-term habituation, a ubiquitous form of learning that plays a key role in basic cognitive functioning. Specifically, behavioral, physiological, and molecular mechanisms of habituation have been explored using a simple model system, the tail-elicited siphon-withdrawal reflex (T-SWR) in the marine mollusk Aplysia californica. Substantial progress has been made on the first and third aims, providing some fundamental insights into the mechanisms by which memories are stored. We have characterized the physiological correlates of short- and long-term habituation. We found that short-term habituation is accompanied by a robust sensory adaptation, whereas long-term habituation is accompanied by alterations in sensory and interneuron synaptic efficacy. Thus, our data indicates memories can be shifted between different sites in a neural network as they are consolidated from short to long term. At the molecular level, we have accomplished microarray analysis comparing gene expression in both habituated and control ganglia. We have identified a network of putatively regulated transcripts that seems particularly targeted towards synaptic changes (e.g. SNAP25, calmodulin) . We are now beginning additional work to confirm regulation of these transcripts and build a more detailed understanding of the cascade of molecular events leading to the permanent storage of long-term memories. On the third aim, we have fostered a nascent neuroscience program via a variety of successful initiatives. We have funded over 11 undergraduate neuroscience scholars, several of whom have been recognized at national and regional levels for their research. We have also conducted a pioneering summer research program for community college students which is helping enhance access of underrepresented groups to life science careers. Despite minimal progress on the second aim, this project has provided a) novel insight into the network mechanisms by

    Although unsafe abortion continues to be a leading cause of maternal mortality in many countries in Asia, the right to safe abortion remains highly stigmatized across the region. The Asia Safe Abortion Partnership, a regional network advocating for safe abortion, produced an animated short film entitled From Unwanted Pregnancy to Safe Abortion to show in conferences, schools and meetings in order to share knowledge about the barriers to safe abortion in Asia and to facilitate conversations on the right to safe abortion. This paper describes the making of this film, its objectives, content, dissemination and how it has been used. Our experience highlights the advantages of using animated films in addressing highly politicized and sensitive issues like abortion. Animation helped to create powerful advocacy material that does not homogenize the experiences of women across a diverse region, and at the same time emphasize the need for joint activities that express solidarity.

  18. An unusual complication of unsafe abortion

    2011-01-01

    Full Text Available Unsafe abortion is a significant medical and social problem worldwide. In developing countries, most of the unsafe abortions are performed by untrained personnel leading to high mortality and morbidity. Case Report: A 30 year-old female, gravida 7, para 6 underwent uterine evacuation for heavy bleeding per vaginum following intake of abortifacient to abort a 14 weeks gestation. The procedure was performed at a rural setup and her bowel was pulled out of the introitus through the perforated wound, an unusual complication of unsafe abortion. Illiteracy, unawareness about health services, and easy accessibility to untrained abortion providers lead to very high mortality and morbidity in India. There is unmet need to bring awareness among the people about the safe and effective methods of contraception and abortion services to avoid such complications.

  19. Health benefits of legal abortion: an analysis.

    1985-01-01

    The abolition of legal abortion in the US would seriously threaten the health, and even the lives, of women and children. Statistics on the relationship between abortion and health attained before and after abortion was legalized were used to project some of the probable consequences of reversing the US Supreme Court's 1973 Roe v. Wade decision. Abortion has been widely practiced throughout US history, but the actual number of procedures performed before some states legalized abortion is unknown. Few legal procedures were performed for medical reasons, yet many illegal abortions took place. In 1955, a panel of experts could only provide a "best estimate" of between 200,000 and 1,200,000 illegally induced abortions occurring annually in the US. The actual number was most likely closer to the higher figure. The complication rates for illegal abortions, most of which were performed by unskilled practitioners in unsafe settings, were much higher than the rates for legal abortion now. Complications were related to ineffective or unsafe methods, Sepsis, particularly with the bacterium "Clostridium prefringens," which causes gas gangrene, was a major problem that has virtually disappeared. Each year prior to the 1970s, more than 100 women in the US died of abortion complications. Due to the fact that vital statistics reflect an incomplete ascertainment of deaths, the actual number of deaths is probably larger, possibly by as much as 50%. In 1983 more than 1.3 million procedures were performed -- a figure close to the estimated number of illegal abortions performed before 1970. In comparison, 672,000 hysterectomies and 424,000 tonsillectomy operations were performed the same year. The number of abortion-related deaths in the US decreased between 1972 and 1980, from 90 to 16. Most of this decrease resulted from the availability and safety of legal abortion. Legal abortion carries an especially low risk of death, particularly when performed in the 1st trimester. For the 1972

  2. Conscientious refusal to assist with abortion.

    Science.gov (United States)

    Dooley, D

    1994-09-10

    Abortion is a moral issue affecting the identity and integrity of physicians and nurses. Ethical reasoning helps reasonable and sincere people who do not agree on abortion to understand the sources of disagreement and to explore shared principles in the differences. Discussions of abortion cannot be limited to the conflict between the rights of a woman to control her reproduction and the rights of a fetus to live. Religious, cultural, feminist, and political beliefs must also be considered. This complexity must be considered when examining whether physicians and nurses have rights to refuse to assist in abortion on conscientious grounds. People with fundamentally different moral outlooks already determine what is morally right or wrong, good or evil. Health professionals who refuse to assist in abortion base their decision on beliefs about moral duties, injunctions of natural law, and the essentially nonnegotiable rights of people to be protected from intentional harm. They know and regret the adverse effects for pregnant women but there is no compelling motivation to change their opposition to abortion. There is no morally neutral position from which to judge conscientious refusals in abortion. Society should develop a position that respects autonomy of belief and grants the right to physicians and nurses to conscientiously refuse to assist in abortions. In those countries where the abortion law grants physicians the right to refuse but not nurses, society needs to reflect on why nurses have been accorded second class professional and moral status. In those countries which have not yet formulated an abortion law, the government should consider how it can find enough health workers who will in good conscience assist in abortions. Governments must first seriously consider a presumptive right to conscientious refusal in abortion before health systems can redistribute sectors of responsibility among health workers and implement changes in recruitment policies for

    1971-05-15

    To determine the long-range psychological effects of therapeutic abortion, 50 women (aged from 13-44 years), who were granted abortions between 1967 and 1968 Because of possible impairment of mental and/or physical health, were analyzed by use of demographic questionnaires, psychological tests, and interviews. Testing revealed that 44 women had psychiatric problems at time of abortion. 43 patients were followed for 3-6 months. The follow-up interviews revealed that 29 patients reacted positively after abortion, 10 reported no significant change and 4 reacted negatively. 37 would definitely repeat the abortion. Women under 21 years of age felt substantially more ambivalent and guilty than older patients. A study of 36 paired pre- and post-abortion profiles showed that 15 initially abnormal tests had become normal. There was a significant increase in contraceptive use among the patients after the abortion, but 4 again became pregnant and 8 were apparently without consistent contraception. It is concluded that the abortions were therapeutic, but physicians are encouraged to be aware of psychological problems in abortion cases. Strong psychological and contraceptive counselling should be exercised.

    Full Text Available 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.

    Full Text Available Background: Whereas the effects of various socio-demographic determinants on a woman's risk of having an abortion are relatively well-documented, less attention has been given to the effect of previous abortions and births. Objective: To study the effect of previous abortions and births on Danish women's risk of an abortion, in addition to a number of demographic and personal characteristics. Data and methods: From the Fertility of Women and Couples Dataset we obtained data on the number of live births and induced abortions by year (1981-2001, age (16-39, county of residence and marital status. Logistic regression analysis was used to estimate the influence of the explanatory variables on the probability of having an abortion in a relevant year. Main findings and conclusion: A woman's risk of having an abortion increases with the number of previous births and previous abortions. Some interactions were was found in the way a woman's risk of abortion varies with calendar year, age and parity. The risk of an abortion for women with no children decreases while the risk of an abortion for women with children increases over time. Furthermore, the risk of an abortion decreases with age, but relatively more so for women with children compared to childless women. Trends for teenagers are discussed in a separate section.

    2013-06-01

    In Ghana, despite the availability of safe, legally permissible abortion services, high rates of morbidity and mortality from unsafe abortion persist. Through interviews with Ghanaian physicians on the front lines of abortion provision, we begin to describe major barriers to widespread safe abortion. Their stories illustrate the life-threatening impact that stigma, financial restraints, and confusion regarding abortion law have on the women of Ghana who seek abortion. They posit that the vast majority of serious abortion complications arise in the setting of clandestine or self-induced second trimester attempts, suggesting that training greater numbers of physicians to perform second trimester abortion is prerequisite to reducing maternal mortality. They also recognized that an adequate supply of abortion providers alone is a necessary but insufficient step toward reducing death from unsafe abortion. Rather, improved accessibility and cultural acceptability of abortion are integral to the actual utilization of safe services. Their insights suggest that any comprehensive plan aimed at reducing maternal mortality must consider avenues that address the multiple dimensions which influence the practice and utilization of safe abortion, especially in the second trimester.

The American College of Obstetricians and Gynecologists supports the expansion of abortion education and an increase in the number and types of trained abortion providers in order to ensure women's access to safe abortions. Integrated medical education and universal opt-out training policies help to lessen the stigma of abortion provision and improve access by increasing the number of abortion providers. This Committee Opinion reviews the current status of abortion education, describes initiatives to ensure the availability of appropriate and up-to-date abortion training, and recommends efforts for integrating and improving abortion education in medical schools, residency programs, and advanced practice clinician training programs.

  13. Aftershocks: The Impact of Clinic Violence on Abortion Services

    OpenAIRE

    2010-01-01

    Between 1973 and 2003, abortion providers in the United States were the targets of over 300 acts of extreme violence. Using unique data on attacks and on abortions, abortion providers, and births, we examine how anti-abortion violence has affected providers' decisions to perform abortions and women's decisions about whether and where to terminate a pregnancy. We find that clinic violence reduces abortion services in targeted areas. Once travel is taken into account, however, the overall effec...

    Full Text Available Objective. Coffee drinking is the main source of caffeine intake among adult population in the western world. It has been reported that low to moderate caffeine intake has beneficial effect on alertness and cognitive functions in healthy subjects. The aim of this study is to evaluate the impact of habitual coffee consumption on cognitive function in hemodialysis patients. Methods. In a cross-sectional study, 86 patients from a single-dialysis centre underwent assessment by the Montreal Cognitive Assessment tool and evaluation for symptoms of fatigue, mood, and sleep disorders by well-validated questionnaires. The habitual coffee use and the average daily caffeine intake were estimated by participants’ response to a dietary questionnaire. Results. Sixty-seven subjects (78% consumed black coffee daily, mostly in low to moderate dose. Cognitive impairment was found in three-quarters of tested patients. Normal mental performance was more often in habitual coffee users (25% versus 16%. Regular coffee drinkers achieved higher mean scores on all tested cognitive domains, but a significant positive correlation was found only for items that measure attention and concentration (P=0.024. Conclusions. Moderate caffeine intake by habitual coffee consumption could have beneficial impact on cognitive function in hemodialysis patients due to selective enhancement of attention and vigilance.

    2002-01-01

    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

    The 50 states of the US were compared in 1971-72 and 1974-75 with respect to percentage apparent conceptions aborted and infant mortality rates attributed to various causes. Only nonvehicle accidental deaths were consistently related to abortion. The correlation is nonlinear; nonvehicle accidental deaths were especially high in states with little or no abortion. A decline in nonvehicle accidental deaths from before to after the Supreme Court decision was most pronounced in states where there were fewest abortions before the decision and where increases in abortion followed the decision.

    Habituation to repetitive painful stimulation may represent an important protection mechanism against the development of chronic pain states. However, the exact neurobiological mechanisms of this phenomenon remain unclear. In this study we (i) explore the somatotopic specificity of pain attenuation over time and (ii) investigate the role of the endogenous opioid system in its development. We investigated 24 healthy volunteers with a paradigm of daily painful stimulation of the left volar forearm for 1 week. Habituation was assessed by comparing pain-related responses (ratings and thresholds) between days 1 and 8. To test whether a repetition-dependent attenuation of pain is restricted to the site of stimulus application or induces additional systemic effects indicative of a central mechanism, we also measured pain-related responses at the contralateral arm and the left leg. To assess the role of the endogenous opioid system in this mechanism, we used the opioid-receptor antagonist naloxone in a double-blind design. Repetitive painful stimulation over several days resulted in a significant habituation to pain at the site of daily stimulation. In addition, we also observed significant pain attenuation at the non-stimulated limbs. This effect was less pronounced at the untreated arm compared to the treated arm and even weaker in the leg, displaying a significant Stimulation-Site x Time interaction. The development of pain habituation was unaffected by the opioid antagonist naloxone. Taken together, these results strongly support the role of central components in the mechanism of pain habituation that do not directly involve the endogenous opioid system.

    2012-10-01

    Unsafe abortion is one of the main causes of maternal mortality and severe morbidity in countries with restrictive abortion laws. In 2007, the International Federation of Gynecology and Obstetrics (FIGO) created a Working Group on the Prevention of Unsafe Abortion and its Consequences (WGPUA). This led to a FIGO initiative with that aim which has the active participation of 43 FIGO member societies. The WGPUA has recommended that the plans of action of the countries participating in the initiative consider several levels of prevention shown to have the potential to successfully reduce unsafe abortions: (1) primary prevention of unintended pregnancy and induced abortion; (2) secondary prevention to ensure the safety of an abortion procedure that could not be avoided; (3) tertiary prevention of further complications of an unsafe abortion procedure that has taken place already, through high-quality postabortion care; and (4) quaternary prevention of repeated abortion procedures through postabortion family planning counseling and contraceptive services. This paper reviews these levels of prevention and the evidence that they can be effective.

    Roberts, J

    1994-08-13

    In the US, violence against abortion clinics is escalating. In July 1994, a doctor who performed abortions and one of his escorts was gunned down outside of an abortion clinic. In March of 1993, another doctor was killed outside of a clinic. That killing prompted passage of a federal law designed to protect abortion providers and clinics from violence. In addition to the individuals murdered, the number of violent incidents against abortion clinics increased four-fold to 250 in 1993. Some elderly physicians feel compelled to continue to perform the procedure instead of retiring because there are no young practitioners to replace them. These physicians note that the young practitioners have no experience with the deaths and illness which resulted from illegal abortions and have not been properly trained by their medical schools. The US Attorney General has dispatched federal marshalls to guard abortion clinics, and local police are increasing their protection of clinics. Abortion protestors say that the new federal law will cause some formerly peaceful protestors to resort to violence.

  17. Habituation of reflexive and motivated behaviour in mice with deficient BK channel function

    2013-11-01

    Full Text Available Habituation is considered the most basic form of learning. It describes the decrease of a behavioural response to a repeated non-threatening sensory stimulus and therefore provides an important sensory filtering mechanism. While some neuronal pathways mediating habituation are well described, underlying cellular/molecular mechanisms are not yet fully understood. In general, there is an agreement that short-term and long-term habituation are based on different mechanisms. Historically, a distinction has also been made between habituation of motivated versus reflexive behaviour. In recent studies in invertebrates the large conductance voltage- and calcium-activated potassium (BK channel has been implicated to be a key player in habituation by regulating synaptic transmission. Here, we tested mice deficient for the pore forming α-subunit of the BK channel for short-term and long-term habituation of the acoustic startle reflex (reflexive behaviour and of the exploratory locomotor behaviour in the open field box (motivated behaviour. Short-term habituation of startle was completely abolished in the BK knock-out mice, whereas neither long-term habituation of startle nor habituation of motivated behaviour was affected by the BK deficiency. Our results support a highly preserved mechanism for short-term habituation of startle across species that is distinct from long-term habituation mechanisms. It also supports the notion that there are different mechanisms underlying habituation of motivated behaviour versus reflexive behaviour.

  1. The abortion culture issue in Serbia

    2011-01-01

    Full Text Available The problem of a large number of abortions in our country was first pointed out as far back as 1935 at the 17th Congress of Yugoslav Physicians. The abortion problem in Serbia is still present today, even though modern science has provided new methods and means which are a logical solution to the dilemma on birth control methods from the health and social aspect. Namely, total abortion rate in Serbia was estimated at 2.76 in the year 2007. It is very high; double the number of the total fertility rate and among the highest in Europe and the world. The term abortion culture was first used, as far as we know, by Henry David in the introduction of the book From Abortion to Contraception - A Resource to Public Policies and Reproductive Behavior in Central and Eastern Europe from 1917 to the Present in 1999, without specifically determining it. The aim of this paper is to identify the most important factors of the deterministic basis of endemic induced abortions in Serbia together with indirectly estimating their connection with the existence, namely nonexistence, of the abortion culture in our country. In that sense, potential factors of abortion incidence in Serbia which emerge from the social system and those connected to the individual level have been considered. In other words, a series of laws and other legal and political documents have been analyzed which are significant for perceiving the abortion matter, as well as institutional frameworks for family planning, health services, educating the youth regarding reproductive health, including findings of numerous researches carried out among women of various age and doctors from 1990 till present day in Serbia. The following most significant factors for the long duration of the abortion problem have been singled out: insufficient knowledge of modern contraception, a belief that modern contraceptive methods are harmful to health and a number of psychological barriers as well as those arising from

    Clearly, abortion in the US continues to be a major medico-legal issue which will not go away. 5 major abortion cases are scheduled for review by the US Supreme Court during its 1982-83 term. Taken together, these 5 cases challenge several of the key conclusions of the Court's review of the abortion question. The primary focus of the cases is the state's power to regulate the abortion decision during the 1st and 2nd trimester of the pregnancy. 2 cases involve ordinances passed by the City of Akron regulating access to abortion in areas such as consent and notification requirements and the location of abortions after the 1st trimester. 2 of the cases involve a Missouri statute also dealing with the requirement that abortions after the 1st trimester be performed in a hospital. The final case involves a Virginia criminal prosecution of a physician accused of violating the state's requirement of in-hospital performance of a 2nd trimester abortion. In the case of Roe v. Wade, the Court had established the "trimester trilogy" governing state regulation of the abortion procedure. For the stage of the pregnancy prior to the end of the 1st trimester, the Court held that the abortion decision and its effectuation must be left to the medical judgment of the pregnant women's attending physician. For the stage of the pregnancy subsequent to the end of the 1st trimester, the Court ruled that the state may promote its interest in the health of the mother by regulating the abortion procedure in ways reasonably related to maternal health. For the stage of pregnancy subsequent to viability, the state may promote its interest in the potentiality of human life by regulation, even prohibiting abortion, except where it is necessary to preserve the mother's life or health. These 5 cases challenge the role of the Court in determining the scope of appropriate state regulation at various stages of the pregnancy.

    In this very short but fiery and violent paper against abortion the author states that most women seeking abortion are actually lying to themselves, pretending they want something which, in reality, they do not want, i.e. an abortion. The laws regulating abortion in most countries are such that a woman is practically forbidden to make an independent decision, despite, or because of the number of counseling sessions and of meetings with doctors that she must go through. Radio, television, newspapers and magazines, friends and relatives, all contribute to make of abortion a run-of-the-mill operation, while it should be seen as scandal, and as the total negation of any maternal instinct.

    Although abortion for health reasons is not considered a crime in Peru, the State does not allow its inclusion in public policy, thus violating women's right to terminate a pregnancy when it affects their health. When examining the article in the Criminal Code which decriminalizes this type of abortion, provisions are identified which protect women and set the conditions to offer this type of service. This document sets the debate about the arguments used by the Peruvian State for not approving a therapeutic abortion protocol which would regulate the provision and financing of therapeutic abortion in public services, and explains why this obligation should be complied with, based on the conceptual framework of "health exception" In addition, it presents two cases brought before the judicial court in which the Peruvian State was found guilty of violating the human rights of two adolescents to whom a therapeutic abortion was denied.

  5. Major trends in recent abortion research.

    Abortion research continues actively. 1 finding has been that abortion has distinct regional features. In Western Europe the rights of the woman in relation to the rights of the fetus are under study while Eastern European researchers examine the effect of long standing available abortion on birthrates, women's health, subsequent pregnancies, and contraceptive use. The increase in illegal abortion shows that improved health and contraceptive services, better data, and changes in restrictive laws are necessary. Changes in the laws, either from less to more liberal or the opposite, have brought about national studies of subsequent trends in abortion, maternal and infant mortality, service facilities, contraceptive practice and fertility. The technique of menstrual regulation, performed within 14 days of a missed menstrual period and before pregnancy can be determined, has created new research problems. It raises the questions of whether menstrual regulation can legally be considered an abortion and whether effectiveness rates can be reliably determined if a large proportion of the women are not even pregnant. The relative risks of menstrual regulation in very early pregnancy and vacuum aspiration and dilation and curretage at a later stage are now being researched. The World Health Organization is planning research of the psychosocial aspects of the relationship between the users and providers of abortion services. Also receiving research attention is the incidence of repeat abortions and the effects of an abortion refused. The fact that overall birthrates have not been substantially changed by the liberalization of abortion laws in the last 20 years appears to be associated with the improvement of contraceptive methods.

    2015-07-01

    Full Text Available Medical abortion is the use of drugs to induce abortion of a fetus. Due to the advances in the field of research , numerous regimens have been formulated to ensure a fast and complete expulsion of the fetus. These regimens also aim to towards reduced post abortal side effects and to decrease the need for surgical evacuation post medical abortion. The objective of this cros s sectional analysis was to study the effectiveness of the WHO safe abortion regimen in a tertiary care hospital . METHODS: A total of 60 patients with pregnancies of 12 to 30 weeks of gestation and in whom a medical abortion was deemed necessary were chosen . After instituting the WHO SAFE ABORTION regimen they were analysed based on indication for pregnancy termination , onset of pain with WHO regimen and time of expulsion as well as post abortal side effects and the need for surgical evacuation due to failure of the WHO safe abortion regimen. Post abortion an ultrasound was done to confirm the success of the regimen . RESULTS: Majority of patients in our study was multiparous and Mean gestational age for pregnancy termination was 20.6 weeks . The most common indication for medical abortion was incidental diagnosis of fetal demise or fetal anomaly on ultrasonography ( 43.6% . The average duration for onset of pain was 3 hours and the average time needed for expulsion was 6 hours from the start of the Abortion regimen . The most common post abortal side effect was excessive bleeding . Only about 13.3 percent patients needed a surgical evacuation due to failure of the regimen. CONCLUSION: This study showed that the WHO safe abortion regimen is highly effective and a desirable method for medical termination of pregnancy , especially in early pregnancy and in patients in whom a surgical method of abortion could pose as a risk . The WHO SAFE ABORTION regimen has minimal post abortal side effects , need for surgical intervention and the time needed for expulsion is less. Hence it

    Full Text Available Background. Induced abortion contributes significantly to maternal mortality in developing countries yet women still seek repeat induced abortion in spite of availability of contraceptive services. The aim of this study is to determine the rate of abortion and contraceptive use among women seeking repeat induced abortion in Western Nigeria. Method. A prospective cross-sectional study utilizing self-administered questionnaires was administered to women seeking abortion in private hospitals/clinics in four geopolitical areas of Ogun State, Western Nigeria, from January 1 to December 31 2012. Data were analyzed using SPSS 17.0. Results. The age range for those seeking repeat induced abortion was 15 to 51 years while the median age was 25 years. Of 2934 women seeking an abortion, 23% reported having had one or more previous abortions. Of those who had had more than one abortion, the level of awareness of contraceptives was 91.7% while only 21.5% used a contraceptive at their first intercourse after the procedure; 78.5% of the pregnancies were associated with non-contraceptive use while 17.5% were associated with contraceptive failure. The major reason for non-contraceptive use was fear of side effects. Conclusion. The rate of women seeking repeat abortions is high in Nigeria. The rate of contraceptive use is low while contraceptive failure rate is high.

    Suarez, H; Caffa, C; Macadar, O

    1992-01-01

    Vestibular habituation was studied in normal subjects and in patients with cerebellar disease using a stimulation paradigm proposed in this paper. Six caloric stimuli were repeated daily in the same ear during six days and electronystagmographic responses at the beginning and the end of that period were compared. The normal behaviour was a clear reduction of the response across time. Two groups of cerebellar patients were identified by their ability to recover from positional imbalance after treatment. Compensated patients responded to repeated caloric stimulation in the same way as normal subjects. Conversely, uncompensated patients increased their response after the stimulation paradigm. The role played by the cerebellum in vestibular plasticity is discussed together with the observed correlation between vestibular habituation and the ability for postural recovery to occur.

  12. [Medical and social implications of abortion].

    Radu, A; Capra, G

    1988-01-01

    In the course of the evolution of human society the problem or idea of interrupting a pregnancy has been faced many times. Romania has adopted a mixed solution to the termination of pregnancy allowing abortions for medical, eugenic, and social reasons. The 1936 penal code allowed only medical abortion, but recent regulations have offered differing solutions. The old regulation not allowing termination of pregnancy or restricting it was in force with minor modifications until 1957. In 1966 a decree was issued that allowed women with 4 children an abortion for special reasons as determined by an abortion committee, but still therapeutic and strictly medical causes predominated. In 1985 a new regulation of medical law prohibited termination of normal pregnancy up to 28 weeks of gestation and infractions were punishable by law. Illegal induced abortion represents an antisocial manifestation that jeopardizes human relationships in society. Induced abortion occurs often in disintegrated family situations. The social implications of the phenomenon of birth are manyfold. Medical intervention is difficult because of the mutilating effect of abortion. The motives are a matter of reflection for physicians and jurists alike.

  13. A measured response: Koop on abortion.

    Science.gov (United States)

    Koop, C E

    1989-01-01

    The available scientific literature on the health effects of abortion on women in the US neither supports nor refutes the premise that abortion contributes to psychological problems. The 250 studies that have considered the psychological aspects of abortion are all flawed methodologically. Needed to resolve this issue is a prospective study of a cohort of US women of childbearing age focused on the psychological effects of failure to conceive, as well as the physical and mental sequelae of pregnancy whether carried to delivery, miscarried, or terminated by abortion. The most desirable such study could be conducted for about US$100 million over a 5-year period; a less expensive yet satisfactory study could be conducted for $10 million over the same time frame. Before such a study can be undertaken, a survey instrument must be designed to eliminate the discrepancy between the number of abortions on record and the number of women who admit to having an abortion on survey. Another issue is that the health effects of abortion cannot easily be separated from the controversial social issues surrounding pregnancy termination.

  14. Ireland: child rape case undermines abortion ban.

    Science.gov (United States)

    1992-11-01

    Abortion has been illegal in Ireland since 1861. This position was written into the national Constitution in 1963 and reconfirmed by referendum in 1983. Contraception is also illegal in the country. The pregnancy of a 14-year old adolescent due to an alleged rape, however, has caused many in Ireland to voice their support for abortion in limited circumstances. Approximately 5000 pregnant women go from Ireland to the United Kingdom annually for abortions. This 14-year old youth also planned to make the crossing, but was blocked from leaving by the Irish police and later by an injunction of the Attorney-General. The Irish Supreme Court upheld the injunction even though the young woman was reportedly contemplating suicide. A national outcry ensued with thousands of demonstrators marching in Dublin to demand the availability of information on abortion and that Irish women be allowed to travel whenever and wherever they desire. 66% of respondents to recent public opinion polls favor abortion in certain circumstances. Ultimately, the Irish Supreme Court reversed their stance to allow pregnant Irish women to travel internationally and gave suicidal Irish women the right to abortions. These decisions were made shortly within the time frame needed for the young lady in question to received a legal abortion in the United Kingdom.

    This study aimed to identify the levels of, and socioeconomic variations in, income-related inequality in induced abortion among Turkish women. The study included 15,480 ever-married women of reproductive age (15-49) from the 2003 and 2008 waves of the Turkish Demographic and Health Survey. The measured inequalities in abortion levels and their changes over time were decomposed into the percentage contributions of selected socioeconomic factors using ordinary least square analysis and concentration indices were calculated. The inequalities and their first difference (difference in inequalities between 2003 and 2008) were decomposed using the approaches of Wagstaff et al. (2003). Higher socioeconomic characteristics (such as higher levels of wealth and education and better neighbourhood) were found to be associated with higher rates of abortion. Inequality analyses indicated that although deprived women become more familiar with abortion over time, abortion was still more concentrated among affluent women in the 2008 survey. The decomposition analyses suggested that wealth, age, education and level of regional development were the most important contributors to income-related inequality in abortion. Therefore policies that (i) increase the level of wealth and education of deprived women, (ii) develop deprived regions of Turkey, (iii) improve knowledge about family planning and, especially (iv) enhance the accessibility of family planning services for deprived and/or rural women, may be beneficial for reducing socioeconomic variations in abortion in the country.

    Although body awareness and pain perception are considered to be parts of the interoceptive system, the relationship between them is unclear. This study examines the association between body awareness and pain habituation, hypothesizing that this association is moderated by pain catastrophizing and mindfulness. Sixty subjects received a mildly aversive electrical stimulus for 60 s, during which they were requested to rate the amount of perceived pain. Complete habituation was indicated by abolition of pain sensation; partial habituation was indicated by a decrease in pain sensation. Individuals who demonstrated complete habituation had lower levels of pain catastrophizing and lower levels of mindfulness. As hypothesized, the association between body awareness and pain habituation was moderated by pain catastrophizing: Among low pain catastrophizers, the higher the body awareness, the stronger the tendency to exhibit complete habituation. Among high pain catastrophizers, the higher the body awareness, the greater the likelihood to present partial habituation.

    Norris, Alison; Bessett, Danielle; Steinberg, Julia R; Kavanaugh, Megan L; De Zordo, Silvia; Becker, Davida

    2011-01-01

    Stigmatization is a deeply contextual, dynamic social process; stigma from abortion is the discrediting of individuals as a result of their association with abortion. Abortion stigma is under-researched and under-theorized, and the few existing studies focus only on women who have had abortions. We build on this work, drawing from the social science literature to describe three groups whom we posit are affected by abortion stigma: Women who have had abortions, individuals who work in facilities that provide abortion, and supporters of women who have had abortions, including partners, family, and friends, as well as abortion researchers and advocates. Although these groups are not homogeneous, some common experiences within the groups--and differences between the groups--help to illuminate how people manage abortion stigma and begin to reveal the roots of this stigma itself. We discuss five reasons why abortion is stigmatized, beginning with the rationale identified by Kumar, Hessini, and Mitchell: The violation of female ideals of sexuality and motherhood. We then suggest additional causes of abortion stigma, including attributing personhood to the fetus, legal restrictions, the idea that abortion is dirty or unhealthy, and the use of stigma as a tool for anti-abortion efforts. Although not exhaustive, these causes of abortion stigma illustrate how it is made manifest for affected groups. Understanding abortion stigma will inform strategies to reduce it, which has direct implications for improving access to care and better health for those whom stigma affects.

    This paper discusses the Brazilian Supreme Court ruling on the case of anencephaly. In Brazil, abortion is a crime against the life of a fetus, and selective abortion of non-viable fetuses is prohibited. Following a paradigmatic case discussed by the Brazilian Supreme Court in 2004, the use of abortion was authorized in the case of a fetus with anencephaly. The objective of this paper is to analyze the ethical arguments of the case, in particular the strategy of avoiding the moral status of the fetus, the cornerstone thesis of the Catholic Church.

    Two samples of women aborting in New York and Connecticut during 1972 and 1973 were studied. In all, six hundred and fifty eight women about to undergo first and second trimester procedures completed a self-administered questionnaire. Items include: demographic, psychosocial and personality parameters, and a detailed review of the decision process leading to abortion. Analyses of the correlates of delay are organized around four components: acknowledgment of pregnancy; seeing a physician ; deciding to abort; and locating a clinic. Other analyses focus on the role of decisional conflict in delay. Methodological issues, implications for educational practice and for theory of decision-making are discussed.

    Infective complications following induced abortions are still a common cause of morbidity and mortality. This review focusses on defining the strategies to improve care of women seeking an induced abortion and to reduce infective complications. We have considered the evidence for screening and cost-effectiveness for antibiotic prophylaxis. Current evidence suggests that treating all women with prophylactic antibiotics in preference to screening and treating is the most cost-effective way of reducing infective complications following induced abortions. The final strategy to prevent infective complications should be individualized for each region/area depending on the prevalence of organisms causing pelvic infections and the resources available.

  7. Immediate Intrauterine Device Insertion Following Surgical Abortion.

    Patil, Eva; Bednarek, Paula H

    2015-12-01

    Placement of an intrauterine device (IUD) immediately after a first or second trimester surgical abortion is safe and convenient and decreases the risk of repeat unintended pregnancy. Immediate postabortion IUD placement is not recommended in the setting of postprocedure hemorrhage, uterine perforation, infection, or hematometra. Otherwise, there are few contraindications to IUD placement following surgical abortion. Sexually transmitted infection screening should follow US Centers for Disease Control and Prevention guidelines. No additional antibiotics are needed beyond those used for the abortion. Placing immediate postabortion IUDs makes highly-effective long-acting reversible contraception more accessible to women.

    Stewart, G K; Goldstein, P J

    1971-04-01

    The impact of the reformed California abortion law, passed in November 1967, is investigated. The law allows interruption of pregnancy in the presence of substantial risk of grave impairment to the mental or physical health of the mother. Septic abortions (complete or incomplete abortion in a patient whose gestation is less than 20 weeks; duration and whose temperature is greater than 100.4 degrees F for more than 4 hours) per 1000 deliveries at San Francisco General Hospital fell from 69 in 1967 to 22 in 1969. The total number of abortions rose from less than 100 per 1000 births in 1968 to more than 250 in 1969. Maternal deaths due to abortion decreased in California per 100,000 live births from 8 to 5 to 3 in 1967, 1968, and 1969. Maternal deaths due to other causes remained relatively fixed in incidence. Maternal deaths have decreased much more markedly in the San Francisco Bay area, where many more therapeutic abortions have been performed, than in the Los Angeles Area, where relatively few therapeutic abortions have been performed. The decrease in septic abortion seems to represent a trend toward decrease in the number of illegal abortions.

  14. Obstetric performance following an induced abortion.

    Science.gov (United States)

    Lowit, Alison; Bhattacharya, Sohinee; Bhattacharya, Siladitya

    2010-10-01

    Abortion has been legalised in most of the Western world for the past four decades. In areas where abortion practices are legal and easy to access, the risk of short-term complications is very low. As most women requesting induced abortion (IA) are young, potential adverse effects on subsequent reproductive function are important to them. This review investigates obstetric performance following IA and highlights methodological problems associated with research in this area. Some data suggest that IA may be linked with an increased risk of low birth weight, miscarriage and placenta previa but could be protective for pre-eclampsia. Current evidence also suggests an association between IA and pre-term birth. Large prospective cohort studies, which permit meaningful subgroup analyses, are needed to provide definitive answers on outcomes following alternative methods of IA and the impact of gestational age at abortion on future obstetric outcomes.

    Bergallo, Paola; Ramón Michel, Agustina

    2016-11-01

    For most of the 20th Century, restrictive abortion laws were in place in continental Latin America. In recent years, reforms have caused a liberalizing shift, supported by constitutional decisions of the countries' high courts. The present article offers an overview of the turn toward more liberal rules and the resolution of abortion disputes by reference to national constitutions. For such purpose, the main legal changes of abortion laws in the last decade are first surveyed. Landmark decisions of the high courts of Argentina, Bolivia, Colombia, and Mexico are then analyzed. It is shown that courts have accepted the need to balance interests and competing rights to ground less restrictive laws. In doing so, they have articulated limits to protection of fetal interests, and basic ideas of women's dignity, autonomy, and equality. The process of constitutionalization has only just begun. Constitutional judgments are not the last word, but they are important contributions in reinforcing the legality of abortion.

  3. High stimulus specificity characterizes anti-predator habituation under natural conditions.

    Science.gov (United States)

    Hemmi, Jan M; Merkle, Tobias

    2009-12-22

    Habituation is one of the most fundamental learning processes that allow animals to adapt to dynamic environments. It is ubiquitous and often thought of as a simple form of non-associative learning. Very little is known, though, about the rules that govern habituation and their significance under natural conditions. Questions about how animals incorporate habituation into their daily behaviour and how they can assure only to habituate to non-relevant stimuli are still unanswered. Animals under threat of predation should be particularly selective about which stimuli they habituate to, since ignoring a real threat could be fatal. In this study, we tested the response of fiddler crabs, Uca vomeris, to repeatedly approaching dummy predators to find out whether these animals habituate to potential predators and to test the selectivity of the habituation process. The crabs habituated to model predators, even though they were confronted with real predators during the same habituation process. They showed remarkable selectivity towards the stimulus: a simple change in the approach distance of the stimulus led to a recovery in their responses. The results strongly indicate that in the context of predator avoidance, habituation under natural conditions is highly selective and a stimulus is not defined just by its current sensory signature, but also its spatio-temporal history.

  4. Abortion in Vietnam: measurements, puzzles, and concerns.

    Goodkind, D

    1994-01-01

    This report summarizes current knowledge about abortion in Vietnam, drawing upon government statistics, survey data, and fieldwork undertaken by the author in Vietnam throughout 1993 and part of 1994. The official total abortion rate in Vietnam in 1992 was about 2.5 per woman, the highest in Asia and worrisome for a country with a still-high total fertility rate of 3.7 children per woman. Vietnamese provinces exhibited substantial variation in both the rate of abortion and the type of procedures performed. Among the hypotheses explored to explain Vietnam's high rate of abortion are the borrowing of family planning strategies from other poor socialist states where abortion is common; current antinatal population policies that interact with a lack of contraceptive alternatives; and a rise in pregnancies among young and unmarried women in the wake of recent free-market reforms. Because family-size preferences are still declining, abortion rates may continue to increase unless the incidence of unwanted pregnancy can be reduced, a goal that Vietnamese population specialists are seeking to achieve.

    Using data from 1,494 Greeks and 1,993 Americans, this study finds that social abortion attitudes are a separate dimension from physical abortion attitudes. According to our structural equation model, abortion attitudes are influenced significantly by religiosity and sexual liberalism. The model explains social abortion attitudes significantly better than physical abortion attitudes. Although the model is applicable to both countries, there are three major differences between Greece and the United States. First, in Greece religiosity has a smaller impact on sexual liberalism, and sexual liberalism has a much weaker impact on both types of abortion attitudes, particularly social abortion attitudes. Second, in Greece religiosity is more strongly related to abortion attitudes than in the United States, particularly to social abortion attitudes. Third, education has a weaker influence in Greece than in the United States.

    BACKGROUND: Complications of unsafe abortion are a major contributor to maternal deaths in developing countries. This study aimed to evaluate the clinical assessment for life-threatening complications and the following management in women admitted with complications from abortions at a rural...... abortion and by trimester. Actual management was compared to the audit criteria and presented by descriptive statistics. RESULTS: Fifty six per cent of the women were in second trimester. Abortion complications were distributed as follows: 53 % incomplete abortions, 28 % threatened abortions, 12...... % inevitable abortions, 4 % missed abortions and 3 % septic abortions. Only one of 238 cases met all criteria of optimal clinical assessment and management. Thus, vital signs were measured in 3 %, antibiotic criteria was met in 59 % of the cases, intravenous fluid resuscitation was administered to 35...

    Forty percent of the world's women are living in countries with restrictive abortion laws, which prohibit abortion or only allow abortion to protect a woman's life or her physical or mental health. In countries where abortion is restricted, women have to resort to clandestine interventions to have...... an unwanted pregnancy terminated. As a consequence, high rates of unsafe abortion are seen, such as in sub-Saharan Africa where unsafe abortion occurs at rates of 18-39/1 000 women. The circumstances under which women obtain unsafe abortion vary and depend on traditional methods known and type of providers...... present. Health professionals are prone to use instrumental procedures to induce the abortion, whereas traditional providers often make a brew of herbs to be drunk in one or more doses. In countries with restrictive abortion laws, high rates of maternal death must be expected and globally an estimated 66...

  9. Freedom of conscience, professional responsibility, and access to abortion.

    1994-01-01

    The current shortage of US physicians willing to perform induced abortions has created a conflict between women's legal right to access to pregnancy termination and physicians' right to refuse participation in a procedure they regard as morally objectionable. According to a 1993 survey, 84% of US counties (housing 30% of women of reproductive age) had no abortion provider. This situation has been exacerbated by a trend to isolate abortion from other medical procedures; in 1992, only 12% of residency programs in obstetrics and gynecology routinely offered training on first-trimester abortion. Also contributing to physician reluctance to become abortion providers have been the violence, death threats, property damage, and harassment of abortion seekers perpetrated by anti-abortion groups. To ameliorate the abortion access crisis, without intruding on the religious convictions of individual physicians, there must be greater collaboration between professional and community groups. Local community officials and pro-choice supporters are urged to use their influence to protect abortion providers from harassment. Professional organizations should provide both symbolic and practical support, e.g. increased status and remuneration, to physicians who commit to the hardship of abortion provision. Older physicians, most aware of the threat to women's health posed by any erosion of abortion rights, should educate their younger colleagues about the importance of safe abortion. Finally, training on abortion techniques should be integrated into the medical school curriculum and rotations should be established at local abortion clinics.

    Requests to increase military aircraft activity in some training facilities in the United States have raised the need to determine if waterfowl and other wildlife are adversely affected by aircraft disturbance. We hypothesized that habituation was a possible proximate factor influencing the low proportion of free-ranging ducks reacting to military aircraft activities in a training range in coastal North Carolina during winters 1991 and 1992. To test this hypothesis, we subjected captive, wild-strain American black ducks (Anas rubripes) and wood ducks (Aix sponsa) to actual and simulated activities of jet aircraft. In the first experiment, we placed black ducks in an enclosure near the center of aircraft activities on Piney Island, a military aircraft target range in coastal North Carolina. The proportion of times black ducks reacted (e.g., alert posture, fleeing response) to visual and auditory aircraft activity decreased from 38 to 6% during the first 17 days of confinement. Response rates remained stable at 5.8% thereafter. In the second experiment, black ducks and wood ducks were exposed to 6 different recordings of jet noise. The proportion of times black ducks reacted to noise decreased (P 0.05) in time-activity budgets of black ducks between pre-exposure to noise and 24 hr after first exposure. Unlike black ducks, wood duck responses to jet noise did not decrease uniformly among experimental groups following initial exposure to noise (P = 0.01). We conclude that initial exposure to aircraft noise elicits behavioral responses from black ducks and wood ducks. With continued exposure of aircraft noise, black ducks may become habituated. However, wood ducks did not exhibit the same pattern of response, suggesting that the ability of waterfowl to habituate to aircraft noise may be species specific.

    To test whether habituation is specific to the stimulus modality, the authors analyzed cross-habituation between the tactile startle response' (TSR) and the acoustic startle response (ASR). The acoustic artifacts of airpuffs used to elicit the TSR were reduced by using a silencer and were effectively masked by background noise of 90-100 dB sound-pressure level. ASR was elicited by 14-kHz tones. TSR and ASR habituated in DBA and BALB mice: both the TSR and ASR habituated to a greater extent in DBA mice than in BALB mice. In both strains, habituation of the TSR did not generalize to the ASR, and vice versa. From this, the authors concluded that habituation of startle is located in the sensory afferent branches of the pathway.

    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

    Background Maternal mortality due to abortion complications stands among the three leading causes of maternal death in Botswana where there is a restrictive abortion law. This study aimed at assessing the patterns and determinants of post-abortion complications. Methods A retrospective institution based cross-sectional study was conducted at four hospitals from January to August 2014. Data were extracted from patients’ records with regards to their socio-demographic variables, abortion complications and length of hospital stay. Descriptive statistics and bivariate analysis were employed. Result A total of 619 patients’ records were reviewed with a mean (SD) age of 27.12 (5.97) years. The majority of abortions (95.5%) were reported to be spontaneous and 3.9% of the abortions were induced by the patient. Two thirds of the patients were admitted as their first visit to the hospitals and one third were referrals from other health facilities. Two thirds of the patients were admitted as a result of incomplete abortion followed by inevitable abortion (16.8%). Offensive vaginal discharge (17.9%), tender uterus (11.3%), septic shock (3.9%) and pelvic peritonitis (2.4%) were among the physical findings recorded on admission. Clinically detectable anaemia evidenced by pallor was found to be the leading major complication in 193 (31.2%) of the cases followed by hypovolemic and septic shock 65 (10.5%). There were a total of 9 abortion related deaths with a case fatality rate of 1.5%. Self-induced abortion and delayed uterine evacuation of more than six hours were found to have significant association with post-abortion complications (p-values of 0.018 and 0.035 respectively). Conclusion Abortion related complications and deaths are high in our setting where abortion is illegal. Mechanisms need to be devised in the health facilities to evacuate the uterus in good time whenever it is indicated and to be equipped to handle the fatal complications. There is an indication for

    Full Text Available Abstract Abortion is legally restricted in most of Latin America where 95% of the 4.4 million abortions performed annually are unsafe. Medical abortion (MA refers to the use of a drug or a combination of drugs to terminate pregnancy. Mifepristone followed by misoprostol is the most effective and recommended regime. In settings where mifepristone is not available, misoprostol alone is used. Medical abortion has radically changed abortion practices worldwide, and particularly in legally restricted contexts. In Latin America women have been using misoprostol for self-induced home abortions for over two decades. This article summarizes the findings of a literature review on women’s experiences with medical abortion in Latin American countries where voluntary abortion is illegal. Women’s personal experiences with medical abortion are diverse and vary according to context, age, reproductive history, social and educational level, knowledge about medical abortion, and the physical, emotional, and social circumstances linked to the pregnancy. But most importantly, experiences are determined by whether or not women have the chance to access: 1 a medically supervised abortion in a clandestine clinic or 2 complete and accurate information on medical abortion. Other key factors are access to economic resources and emotional support. Women value the safety and effectiveness of MA as well as the privacy that it allows and the possibility of having their partner, a friend or a person of their choice nearby during the process. Women perceive MA as less painful, easier, safer, more practical, less expensive, more natural and less traumatic than other abortion methods. The fact that it is self-induced and that it avoids surgery are also pointed out as advantages. Main disadvantages identified by women are that MA is painful and takes time to complete. Other negatively evaluated aspects have to do with side effects, prolonged bleeding, the possibility that it

    Habituation of looking time has become the standard method for studying cognitive processes in infancy. This method has a long history and derives from the study of memory and habituation itself. Often, however, it is not clear how researchers make decisions about how to implement habituation as a tool to study processes such as categorization, object representation, and memory. This article describes the challenges for implementing this tool, and describes a set of best practices for its use...

    Individuals with anxiety disorders have previously demonstrated abnormal habituation to aversiveness over time. As anxiety sensitivity (AS), or an individuals’ propensity to fear anxiety-related sensations, has been shown to be a risk factor for anxiety disorders (particularly panic disorder), the present study examined whether AS was also associated with abnormal habituation. This association was examined in two independent samples of undergraduates (total N=178). Habituation was operational...

    Habituation, or the relatively permanent waning of a response as a result of repeated stimulation, is a form of behavioural plasticity that allows animals to filter out irrelevant stimuli and to focus selectively on important stimuli. Individuals that fail to habituate might be at a disadvantage if they continue to respond to irrelevant stimuli; therefore, habituation can have adaptive significance. In this study we compared rates of behaviour over time toward three different ecologically-rel...

  1. Induction of fetal demise before abortion.

    Diedrich, Justin; Drey, Eleanor

    2010-06-01

    For decades, the induction of fetal demise has been used before both surgical and medical second-trimester abortion. Intracardiac potassium chloride and intrafetal or intra-amniotic digoxin injections are the pharmacologic agents used most often to induce fetal demise. In the last several years, induction of fetal demise has become more common before second-trimester abortion. The only randomized, placebo-controlled trial of induced fetal demise before surgical abortion used a 1 mg injection of intra-amniotic digoxin before surgical abortion at 20-23 weeks' gestation and found no difference in procedure duration, difficulty, estimated blood loss, pain scores or complications between groups. Inducing demise before induction terminations at near viable gestational ages to avoid signs of life at delivery is practiced widely. The role of inducing demise before dilation and evacuation (D&E) remains unclear, except for legal considerations in the United States when an intact delivery is intended. There is a discrepancy between the one published randomized trial that used 1 mg intra-amniotic digoxin that showed no improvement in D&E outcomes and observational studies using different routes, doses and pre-abortion intervals that have made claims for its use. Additional randomized trials might provide clearer evidence upon which to make further recommendations about any role of inducing demise before surgical abortion. At the current time, the Society of Family Planning recommends that pharmacokinetic studies followed by randomized controlled trials be conducted to assess the safety and efficacy of feticidal agents to improve abortion safety.

    The habituation of cell cultures to cellulose biosynthesis inhibitors such as dichlobenil (DCB) represents a valuable tool to improve our knowledge of the mechanisms involved in plant cell wall structural plasticity.Maize cell lines habituated to lethal concentrations of DCB were able to grow through the acquisition of a modified cell wall in which cellulose was partially replaced by a more extensive network of arabinoxylans.The aim of this work was to investigate the phenolic metabolism of non-habituated and DCB-habituated maize cell cultures.Maize cell cultures were fed [14C]cinnamate and the fate of the radioactivity in different intra-protoplasmic and wall-localized fractions throughout the culture cycle was analyzed by autoradiography and scintillation counting.Non-habituated and habituated cultures did not markedly differ in their ability to uptake exogenous [14C]cinnamic acid.However,interesting differences were found in the radiolabeling of low- and high-Mr metabolites.Habituated cultures displayed a higher number and amount of radiolabeled low-Mr compounds,which could act as reserves later used for polysaccharide feruloylation.DCB-habituated cultures were highly enriched in esterified [14C]dehydrodiferulates and larger coupling products.In conclusion,an extensive and early cross-linking of hydroxycinnamates was observed in DCB-habituated cultures,probably strengthening their cellulose-deficient walls.

    Repeated presentation of food cues results in habituation in adults, as demonstrated by a decrement in salivary responding that is reversed by presenting a new food cue in adults. Food reinforced behavior in animals shows the same pattern of responding, with a decrease in responding to obtain the food, followed by a recovery of responding when a new food is presented. The present study assessed whether children would show the same pattern of a decrement of food reinforced responding followed by recovery of responding when a new food is presented for both salivation and food reinforcement tasks. Subjects were assigned to one of two groups that differed in the trial that the new food stimulus was presented to ensure recovery was specific to the introduction of the new food stimulus. In the salivation task, subjects were provided repeated olfactory presentations of a cheeseburger with apple pie as the new food stimulus, while in the food reinforcement task subjects worked for the opportunity to consume a cheeseburger, followed by the opportunity to work for consumption of apple pie. Subjects in both groups showed a decrement in salivary and food reinforced responding to repeated food cues followed by immediate recovery of responding on the trial when a new food was presented. Subjects increased their energy intake by over 30% in the food reinforcement task when a new food was presented. These results are consistent with the general process theory of motivation that suggests that changes in food reinforced responding may be due in part to habituation.

    2015-01-01

    Despite a common perception that fruit juice is healthy, fruit juice contains high amounts of naturally occurring sugar without the fibre content of the whole fruit. Frequent fruit juice consumption may therefore contribute to excessive sugar consumption typical of the Western society. Although excess sugar intake is associated with high blood pressure (BP), the association between habitual fruit juice consumption and BP is unclear. The present study investigated the association of fruit juice consumption with brachial and central (aortic) BP in 160 community dwelling adults. Habitual fruit juice consumption was measured using a 12 month dietary recall questionnaire. On the same day, brachial BP was measured and central (aortic) BP was estimated through radial artery applanation. Frequency of fruit juice consumption was classified as rare, occasional or daily. Those who consumed fruit juice daily, versus rarely or occasionally, had significantly higher central systolic BP (F (2, 134) = 6.09, p fruit juice daily rather than rarely or occasionally. In conclusion, more frequent fruit juice consumption was associated with higher central BPs.

    Bovine abortion of unknown infectious aetiology still remains a major economic problem. In this study, we focused on a new possible abortigenic agent called Parachlamydia acanthamoebae. Retrospective samples (n=235) taken from late-term abortions in cattle were investigated by real-time diagnostic PCR for Chlamydiaceae and Parachlamydia spp., respectively. Histological sections of cases positive by real-time PCR for any Chlamydia-related agent were further examined by immunohistochemistry using specific antibodies. Chlamydophila abortus was detected only in three cases (1.3%) by real-time PCR and ArrayTube Microarray playing a less important role in bovine abortion compared to the situation in small ruminants in Switzerland. By real-time PCR as many as 43 of 235 (18.3%) cases turned out to be positive for Parachlamydia. The presence of Parachlamydia within placental lesions was confirmed in 35 cases (81.4%) by immunohistochemistry. The main histopathological feature in parachlamydial abortion was purulent to necrotizing placentitis (25/43). Parachlamydia should be considered as a new abortigenic agent in Swiss cattle. Since Parachlamydia may be involved in lower respiratory tract infections in humans, bovine abortion material should be handled with care given the possible zoonotic risk.

    2000-11-01

    Abortion is illegal in Brazil except when performed to save the woman's life or in cases of rape. This paper gives a brief history of parliamentary and extra-parliamentary efforts to change abortion-related legislation in Brazil in the past 60 years, the contents of some of the 53 bills that have been tabled in that time, the non-governmental stakeholders involved and the debate itself in recent decades. The authorities in Brazil have never assumed full public responsibility for reproductive health care or family planning, let alone legal abortion; the ambivalence of the medical profession is an important obstacle. Most politicians avoid getting involved in the abortion debate, but the majority of bills in the 1990s have favoured less restrictive legislation. Incremental legislative and health service changes could help to improve the situation for women. Advocacy is probably the most important action, to promote an environment conducive to change. Clandestine abortion is a serious public health problem in Brazil, and the inadequacy of family planning services is one of the causes of this problem. The solutions should be made a priority for the Brazilian public health system.

    Abortion is not only a major cause of obstetric hospitalization in poor countries, but it also represents the failure of the public health system to provide enough information about contraceptive methods and thus prevent pregnancies. In Brazil, the high utilization rates of health facilities due to abortions reflect the ongoing difficulties with family planning and contraception. In addition, mortality resulting from abortions serves as an indicator of the quality of abortion procedures, an important point in a country where the practice is illegal and therefore done clandestinely. In this study, we analyzed the rates of mortality resulting from abortions among women 10 to 54 years old, including women who died from spontaneous and induced abortion, from 1980 to 1995, for the various regions of the country. The information we used came from the mortality data bank of the public health system of the Ministry of Health. Population data were obtained from the Brazilian Institute for Geography and Statistics. We studied 2,602 deaths, 15% of which were due to missed abortion, spontaneous abortion, or legally permitted induced abortion. The other 85% of the deaths were due to illegal induced abortions or to nonspecified abortions. The mortality rates from abortion-related causes have steadily decreased in all the regions of Brazil, but this improvement has been unevenly distributed in the country. The region with the smallest decrease in this rate (38% over 15 years) was the Northeast. The age of women dying from abortions progressively declined over the period studied.

  9. Constructing abortion as a social problem: “Sex selection” and the British abortion debate

    Science.gov (United States)

    2017-01-01

    Between February 2012 and March 2015, the claim that sex selection abortion was taking place in Britain and that action needed to be taken to stop it dominated debate in Britain about abortion. Situating an analysis in sociological and social psychological approaches to the construction of social problems, particularly those considering “feminised” re-framings of anti-abortion arguments, this paper presents an account of this debate. Based on analysis of media coverage, Parliamentary debate and official documents, we focus on claims about grounds (evidence) made to sustain the case that sex selection abortion is a British social problem and highlight how abortion was problematised in new ways. Perhaps most notable, we argue, was the level of largely unchallenged vilification of abortion doctors and providers, on the grounds that they are both law violators and participants in acts of discrimination and violence against women, especially those of Asian heritage. We draw attention to the role of claims made by feminists in the media and in Parliament about “gendercide” as part of this process and argue that those supportive of access to abortion need to critically assess both this aspect of the events and also consider arguments about the problems of “medical power” in the light of what took place.

    Objective To investigate the effects of allograft inflammatory factor-1(AIF-1)and (RANTES) in sera and deciduas on unexplained early spontaneous abortion.Methods AIF-1 and RANTES were examined in sera and deciduas/endometria of 43 unexplained early spontaneous abortion women (group A),40 healthy women with early pregnancy(group B)and 20 healthy women with no pregnancy (group C). Immunohistochemistry and enzyme linked immunosorbent assay (ELISA) were used in this study. Results AIF-1 protein was expressed both in deciduas of group A and in endometria of group C.In group A, H scores in the recurrent abortion deciduas specimens were significantly greater than those in the first abortion;in endometrium,expression of AIF-1 was greater in the secretory than in proliferative phase of group C.In group B,concentrations of RANTES in sera were higher in 7th-8th week of pregnancy than in 6th-7th and >8th week of pregnancy;expression of AIF-1 protein showed a negative correlation with RASNTES concentration;a significant increase of the RANTES levels in sera and tissue was observed in group B. Conclusion These results demonstrate, for the first time,that AIF-1 are expressed in deciduas of unexplained spontaneous abortion suggesting that AIF-1 involve in alloimmune abortion; RANTES might act as a novel blocking antibody;AIF-1 and RANTES might act as reliable markers for diagnosis of early alloimmune abortion.

    Since the decriminalisation of abortion in 2006, women in Colombia have continued to seek clandestine abortions, endangering their health and contributing to maternal mortality and morbidity. The goal of this study was to explore physicians' opinions towards and knowledge about legal abortion in Bogotá, Colombia, and key barriers to the legal abortion access. We conducted 13 key informant interviews followed by a survey with a probability sample of 49 doctors working in public hospitals in Bogotá. Interview and survey data showed lack of technical experience in the provision of abortion and nuanced opinions towards its practice. Key informants described ignorance and lack of abortion training in medical schools as key barriers to provision. In the survey, 16/49 respondents had performed an abortion, 24/49 had referred a woman for an abortion and only 33/49 showed correct knowledge of the law.

  18. Ethical considerations on methods used in abortions.

    Science.gov (United States)

    Kluge, Eike-Henner W

    2015-03-01

    There is a fundamental inconsistency in Western society's treatment of non-human animals on the one hand, and of human foetuses on the other. While most Western countries allow the butchering of animals and their use in experimentation, this must occur under carefully controlled conditions that are intended to minimize their pain and suffering as much as possible. At the same time, most Western countries permit various abortion methods without similar concerns for the developing fetus. The only criteria for deciding which abortion method is used centre in the stage of the pregnancy, the size of the fetus, the health of the pregnant woman and the physician's preference. This is out of step with the underlying ethos of animal cruelty legislation, cannot be justified ethically and should be rectified by adjusting abortion methods to the capacity of the fetus to experience nociception and/or pain.

  19. The politics of abortion and contraception

    Directory of Open Access Journals (Sweden)

    Drezgić Rada

    2004-01-01

    Full Text Available In this article the author challenges several dominant positions that are relevant for understanding demographic trends and contraceptive practices as well as their mutual relationship. First, the author rejects the assumed direct connection between high abortion rates and low fertility. Second, the author challenges the thesis according to which abortions come about because of the lack of contraception and proposes that high abortion rates result from failing contraception i.e. from high failing rates of coitus interruptus which is a preferred method of birth control by men and women in Serbia. Finally, the author argues that giving control over reproductive risk to men does not make women passive victims of male domination. Rather women are, it is argued, active agents in reproducing hegemonic gender roles and relations. In addition, the author shows how gender power relations formed at the micro level may be consequential for macro level politics.

  20. Basal body temperature recordings in spontaneous abortion.

    Cohen, J; Iffy, L; Keyser, H H

    1976-01-01

    Basal body temperature (BBT) charts taken during the cycle of conception in cases that resulted in spontaneous abortion appear to provide the best available information concerning events associated with time of fertilization in doomed gestations. This study is based on a series of 227 patients who had early spontaneous abortion occurring between January 1967 and December 1974. A diagnosis of pregnancy initiated regular assays of urinary estrogen and pregnanediol excretion. Patients were instructed to report any bleeding episode which might occur, and to preserve all tissues that might be expelled. A total of 11 basal body temperature charts were obtained from patients who had subsequent early spontaneous abortion. Chromosome studies and histologic investigations were conducted. Another group of 11 consecutive BBT records were obtained from patients who had normal deliveries. The study shows that women with normal cycles experience a midcycle temperature rise requiring 1 to 3 days. In subsequent patients, this time limit was exceeded in 7 out of 11 cases of early abortion, and in 4 of 11 fertilization that resulted in an apparently normal gestation and infant. As temperature rise resulted from vigorous progesterone secretion by the corpus luteum, subnormal levels indicate inadequate steroidogenesis in the early luteal phase, and falling estrogen and progesterone levels predicted fetal demise in all cases. These findings are useful in the management of early pregnancy that follows repeated spontaneous first trimester abortions or a prolonged period of infertility. They also confirm experimental and clinical evidence regarding the role of ovulation defects in the occurrence of various types of reproductive wastage, including early abortion, anatomic and chromosome defects of the embryo and others. Prospective studies of cycles of conception through BBT recordings/hormone assays may shed light in the understanding of defects of human reproduction.

  1. Abortion laws in African Commonwealth countries.

    Science.gov (United States)

    Cook, R J; Dickens, B M

    1981-01-01

    This paper provides an overview of the range of current (1981) abortion laws in the African Commonwealth countries, traces the origins of the laws to their colonial predecessors, and discusses legal reform that would positively provide for legal termination of pregnancy. The authors claim that the range of these laws demonstrates an evolution that leads from customary/common law (Lesotho and Swaziland) to basic law (Botswana, The Gambia, Malawi, Mauritius, Nigeria's Northern States and Seychelles) to developed law (Ghana, Kenya, Nigeria's Southern States, Sierra Leone, and Uganda), and, finally, to advanced law (Zambia and Zimbabwe). The authors call for treating abortion as an issue of health and welfare as opposed to one of crime and punishment. Since most of the basic law de jure is treated and administered as developed law de facto, the authors suggest decriminalizing abortion and propose ways in which to reform the law: clarifying existing law; liberalizing existing law to allow abortion based upon certain indications; limiting/removing women's criminal liability for seeking an abortion; allowing hindsight contraception; protecting providers treating women in good faith; publishing recommended fees for services to protect poor women; protecting providers who treat women with incomplete abortion; and punishing providers who fail to provide care to women in need, with the exception of those seeking protection under a conscience clause. The authors also suggest clarifying the means by which health services involving pregnancy termination may be delivered, including: clarification of the qualifications of practitioners who may treat women; specification of the facilities that may treat women, perhaps broken down by gestational duration of the pregnancy; specifying gestational limits during which the procedure can be performed; clarifying approval procedures and consents; and allowing for conscientious objections to performing the procedure.

  2. Catholic options in the abortion debate.

    Science.gov (United States)

    Maguire, D C

    1990-01-01

    The little-known Roman Catholic theological doctrine of probabilism, an ethical system explicated in all manuals of moral theology, is explained using as an example the dilemma of abortion. Probabilism is based on the notion that a doubtful moral obligation may not be imposed as though it were certain. "Ubi dubium, ibi libertas," means where there is doubt, there is freedom. There are 2 types of moral probability, intrinsic probability, where the individual, without the help of moral theologians, perceives the inapplicability of a particular moral teaching; and extrinsic probability, which involves reliance on the findings of 5 or 6 reputable moral theologians, who may hold a liberal view. Probabilism implies a reasonable doubt, and one's reasons must be cogent, but not necessarily conclusive. Today's abortion debate is an example of a respectable debate, where the liberal view has been endorsed by a number of reputable religious or other humanitarian bodies that in some cases abortion is not always immoral. Other examples in history are the view once taught by the church that taking interest on loans was immoral, that depriving slaves and women of civil rights on non-Catholics of religious or political freedom was moral. For today's legislators, there is a precedent throughout theological history for the state permitting an evil: both St. Augustine and St. Thomas Aquinas wrote that prostitution, although evil, should not be outlawed, because worse evils would occur with prohibition. Legislators who personally find abortion always immoral can support a Roe V. Wade decision because 1) it does not require anyone to have an abortion, and 2) the abortion debate, among Catholics, and non-Catholics is not settled.

    This study describes the pattern of decision as reported by women undergoing elective abortion. The results are based on interviews with 45 of 67 women admitted to the Department of Obstetrics and Gynecology, University Hospital of Tromsø, during a two month period in 1988. All women had informed, and most often consulted, at least one person before making the decision, usually their partner and/or a female friend. The majority of the persons consulted supported her, whatever her decision. According to the women, they made the women, the final decision themselves. Two women were persuaded by their partner to decide to have an elective abortion.

    In countries of the CCEE region (Countries of Central and Eastern Europe) the very high incidence of pregnancy termination is characteristic of family planning and the notion 'contraception instead of abortion' has not yet been achieved. The causes and consequences of this unfortunate situation will be reviewed: the reproductive health indicators in the area; the status of contraceptive use and of abortion; the impact of legislation in the different countries; and the efforts to achieve changes. The conclusions of the 'Szeged Declaration' which led to an increase in contraceptive prevalence will be discussed.

    VO2max is associated with many factors, including age, gender, physical activity, and body composition. It is popularly believed that habitual smoking lowers aerobic fitness. PURPOSE: to determine the effect of habitual smoking on VO2max after controlling for age, gender, activity and BMI. METHODS: 2374 men and 375 women employed at the NASA/Johnson Space Center were measured for VO2max by indirect calorimetry (RER>=1.1), activity by the 11 point (0-10) NASA Physical Activity Status Scale (PASS), BMI and smoking pack-yrs (packs day*y of smoking). Age was recorded in years and gender was coded as M=1, W=0. Pack.y was made a categorical variable consisting of four levels as follows: Never Smoked (0), Light (1-10), Regular (11-20), Heavy (>20). Group differences were verified by ANOVA. A General Linear Models (GLM) was used to develop two models to examine the relationship of smoking behavior on VO2max. GLM #1(without smoking) determined the combined effects of age, gender, PASS and BMI on VO2max. GLM #2 (with smoking) determined the added effects of smoking (pack.y groupings) on VO2max after controlling for age, gender, PASS and BMI. Constant errors (CE) were calculated to compare the accuracy of the two models for estimating the VO2max of the smoking subgroups. RESULTS: ANOVA affirmed the mean VO2max of each pack.y grouping decreased significantly (psmoking exposure increased. GLM #1 showed that age, gender, PASS and BMI were independently related with VO2max (R2 = 0.642, SEE = 4.90, pSmoked, the effects on VO2max from Light and Regular smoking habits were -0.83 and -0.85 ml.kg- 1.min-1 respectively (psmoking on VO2max was -2.56 ml.kg- 1.min-1 (psmoking group in GLM #2 was smaller than the CE s of the smoking group counterparts in GLM #1. CONCLUSIONS: After accounting for the effects of gender, age, PASS and BMI the effect of habitual smoking on reducing VO2max is minimal, about 0.85 ml/kg/min, until the habit exceeds 20 pack.y at which point an additional decrease

    This paper communicates the presence of aberrant microscopic forms of Histoplasma capsulatum in a sample ob-tained by scrapping of the skin lesion and stained with a rapid modification of the Grocott technique.The AIDS patient was treated with cream contained corticoids and antifungal and antibacterial antibiotics by an erroneous diagnosis.Once the etiologic diagnosis was achieved,oral itraconazol was administrated at the daily dose of 400 mg during at least six months.These non habitual forms described in the literature as"aberrant variants", can be interpreted as an"adaptive phenomenon"of this termodimorphic fungal specie,as response of the eco-logic alterations produced by antibiotic on the local antagonic bacterial microbiota,the deleterous activity of antifungal on the fungal cells and the local inmunodepression produced by the corticoids.

  10. Using sensor habituation in mobile robots to reduce oscillatory movements in narrow corridors.

    Science.gov (United States)

    Chang, Carolina

    2005-11-01

    Habituation is a form of nonassociative learning observed in a variety of species of animals. Arguably, it is the simplest form of learning. Nonetheless, the ability to habituate to certain stimuli implies plastic neural systems and adaptive behaviors. This paper describes how computational models of habituation can be applied to real robots. In particular, we discuss the problem of the oscillatory movements observed when a Khepera robot navigates through narrow hallways using a biologically inspired neurocontroller. Results show that habituation to the proximity of the walls can lead to smoother navigation. Habituation to sensory stimulation to the sides of the robot does not interfere with the robot's ability to turn at dead ends and to avoid obstacles outside the hallway. This paper shows that simple biological mechanisms of learning can be adapted to achieve better performance in real mobile robots.

  11. Joint loads in marsupial ankles reflect habitual bipedalism versus quadrupedalism.

    Directory of Open Access Journals (Sweden)

    Kristian J Carlson

    Full Text Available Joint surfaces of limb bones are loaded in compression by reaction forces generated from body weight and musculotendon complexes bridging them. In general, joints of eutherian mammals have regions of high radiodensity subchondral bone that are better at resisting compressive forces than low radiodensity subchondral bone. Identifying similar form-function relationships between subchondral radiodensity distribution and joint load distribution within the marsupial postcranium, in addition to providing a richer understanding of marsupial functional morphology, can serve as a phylogenetic control in evaluating analogous relationships within eutherian mammals. Where commonalities are established across phylogenetic borders, unifying principles in mammalian physiology, morphology, and behavior can be identified. Here, we assess subchondral radiodensity patterns in distal tibiae of several marsupial taxa characterized by different habitual activities (e.g., locomotion. Computed tomography scanning, maximum intensity projection maps, and pixel counting were used to quantify radiodensity in 41 distal tibiae of bipedal (5 species, arboreal quadrupedal (4 species, and terrestrial quadrupedal (5 species marsupials. Bipeds (Macropus and Wallabia exhibit more expansive areas of high radiodensity in the distal tibia than arboreal (Dendrolagus, Phascolarctos, and Trichosurus or terrestrial quadrupeds (Sarcophilus, Thylacinus, Lasiorhinus, and Vombatus, which may reflect the former carrying body weight only through the hind limbs. Arboreal quadrupeds exhibit smallest areas of high radiodensity, though they differ non-significantly from terrestrial quadrupeds. This could indicate slightly more compliant gaits by arboreal quadrupeds compared to terrestrial quadrupeds. The observed radiodensity patterns in marsupial tibiae, though their statistical differences disappear when controlling for phylogeny, corroborate previously documented patterns in primates and

    Full Text Available Introduction : Mobile phone usage is widespread and concerns have been raised on the safety of its long-term usage. The electromagnetic fields emitted from mobile can penetrate skull and deposit energy 4-6 cm into the brain resulting in heating of the tissue. In this study, we explore a possible relationship between prolonged mobile phone usage and sensorineural deafness. Materials and Methods: The study was conducted in a medical college situated in rural India. A total of 100 persons between the age group of 20-45years using mobile phone for at least 5 years are selected and screened for sensorineural deafness. Use of cellular phones was assessed by a questionnaire. Mean number of daily calls and minutes were asked for to calculate the cumulative use in hours for all years. The most frequently used ear during cellular phone calls was noted, or whether both ears were used equally. Otoscopic examinations were performed by an otolaryngologist before testing in order to rule out any external or middle ear pathology that could affect audiometric measurements. The hearing levels of subjects were tested using pure tone audiometry. Results : One hundred subjects who are habitual mobile phone users were screened by pure tone audiometry. It is found that the prevalence of sensorineural deafness was 3% and there is a linear relationship between the duration of mobile phone use and the degree of the severity of deafness. Conclusion : The prevalence of sensorineural deafness in our study in habitual mobile users is 3%. It is not clearly known whether mobile phone use is the direct cause of deafness in these subjects but the absence of other causes might point towards its etiological role.

  13. Algorithm for Determination of Orion Ascent Abort Mode Achievability

    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.

    Full Text Available Background: Spontaneous abortion is the most common adverse pregnancy outcome. We aimed to investigate a possible link between nutrient deficiencies and the risk of spontaneous abortion. Materials and Methods: This case-control study included the case group (n=331 experiencing a spontaneous abortion before 14 weeks of pregnancy and the control group (n=331 who were healthy pregnant women over 14 weeks of pregnancy. The participants filled out Food Frequency Questionnaire (FFQ, in which they reported their frequency of consumption for a given serving of each food item during the past three months, on a daily, weekly or monthly basis. The reported frequency for each food item was converted to a daily intake. Then, consumption of nutrients was compared between the two groups. Results: There are significant differences between the two groups regarding consumed servings/day of vegetables, bread and cereal, meat, poultry, fish, eggs, beans, fats, oils and dairy products (P=0.012, P<0.001, P=0.004, P<0.001, P=0.019, respectively. There are significant differences between the two groups in all micronutrient including folic acid, iron, vitamin C, vitamin B6, vitamin B12 and zinc (P<0.001. Conclusion: Poor nutrientions may be correlated with increased risk of spontaneous abortion

    2016-06-01

    In 2007 abortion was legalized in the Federal District of Mexico, making it the largest jurisdiction in Latin America, outside of Cuba, to allow women to have abortions on request during the first trimester of pregnancy. While the implications of the law for women's health and maternal mortality have been investigated, its potential association with fertility behavior has yet to be assessed. We examine metropolitan-area differences in overall and parity-specific childbearing, as well as the age pattern of childbearing between 2000 and 2010 to identify the contribution of abortion legalization to fertility in Mexico. Our statistical specification applies difference-in-difference regression methods that control for concomitant changes in other socioeconomic predictors of fertility to assess the differential influence of the law across age groups. In addition, we account for prior fertility levels and change to better separate the effect of the law from preceding trends. Overall, the evidence suggests a systematic association between abortion legalization and fertility. The law appears to have contributed to lower fertility in Mexico City compared to other metropolitan areas and prior trends. The influence is mostly visible among women aged 20-34 in connection with the transition to first and second child, with limited impact on teenage fertility. There is some evidence that its effect might be diffusing to the Greater Mexico City Metropolitan area.

    1997-06-01

    Two folk medical conditions, "delayed" (atrasada) and "suspended" (suspendida) menstruation, are described as perceived by poor Brazilian women in Northeast Brazil. Culturally prescribed methods to "regulate" these conditions and provoke menstrual bleeding are also described, including ingesting herbal remedies, patent drugs, and modern pharmaceuticals. The ingestion of such self-administered remedies is facilitated by the cognitive ambiguity, euphemisms, folklore, etc., which surround conception and gestation. The authors argue that the ethnomedical conditions of "delayed" and "suspended" menstruation and subsequent menstrual regulation are part of the "hidden reproductive transcript" of poor and powerless Brazilian women. Through popular culture, they voice their collective dissent to the official, public opinion about the illegality and immorality of induced abortion and the chronic lack of family planning services in Northeast Brazil. While many health professionals consider women's explanations of menstrual regulation as a "cover-up" for self-induced abortions, such popular justifications may represent either an unconscious or artful manipulation of hegemonic, anti-abortion ideology expressed in prudent, unobtrusive and veiled ways. The development of safer abortion alternatives should consider women's hidden reproductive transcripts.

    Abort trajectory is a passage that ensures the astronauts to return safely to the earth when an emergency occurs. Firstly,the essential elements of mission abort are analyzed entirely based on summarizing the existing studies. Then,abort trajectory requirement and rational selection for different flight phases of typical manned lunar mission are discussed specifically. Considering a trade-off between the two primary constrains of an abort,the return time of flight and energy requirement,a general optimizing method for mission abort is proposed. Finally,some suggestions are given for China’s future manned lunar landing mission.

    Background 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’. Discussion However, each of these reasons is based on false premises. Unsafe abortion is a...

    The Esigma70-dependent N25 promoter is rate-limited at promoter escape. Here, RNA polymerase repeatedly initiates and aborts transcription, giving rise to a ladder of short RNAs 2-11 nucleotides long. Certain mutations in the initial transcribed sequence (ITS) of N25 lengthen the abortive initiation program, resulting in the release of very long abortive transcripts (VLATs) 16-19 nucleotides long. This phenomenon is completely dependent on sequences within the first 20 bases of the ITS since altering sequences downstream of +20 has no effect on their formation. VLAT formation also requires strong interactions between RNA polymerase and the promoter. Mutations that change the -35 and -10 hexamers and the intervening 17 base pair spacer away from consensus decrease the probability of aborting at positions +16 to +19. An unusual characteristic of the VLATs is their undiminished levels in the presence of GreB, which rescues abortive RNAs (abortive release at VLAT positions.

    We explored the psychometric properties of 15 survey questions that assessed abortion providers' perceptions of stigma and its impact on providers' professional and personal lives referred to as the Abortion Provider Stigma Survey (APSS). We administered the survey to a sample of abortion providers recruited for the Providers' Share Workshop (N = 55). We then completed analyses using Stata SE/12.0. Exploratory factor analysis, which resulted in 13 retained items and identified three subscales: disclosure management, resistance and resilience, and discrimination. Stigma was salient in abortion provider's lives: they identified difficulties surrounding disclosure (66%) and felt unappreciated by society (89%). Simultaneously, workers felt they made a positive contribution to society (92%) and took pride in their work (98%). Paired t-test analyses of the pre- and post-Workshop APSS scores showed no changes in the total score. However, the Disclosure Management subscale scores were significantly lower (indicating decreased stigma) for two subgroups of participants: those over the age of 30 and those with children. This analysis is a promising first step in the development of a quantitative tool for capturing abortion providers' experiences of and responses to pervasive abortion stigma.

    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.

    Plants and herbs have been used to induce abortions but there is very little published information describing the commonly used ones. The purpose of this report is to describe the herbal products used to induce abortions, and to enhance awareness and understanding of their toxic effects. A descriptive retrospective survey was conducted on the calls received by the Montevideo Poison Centre between 1986 and 1999 concerning the ingestion of herbal infusions with abortive intent. A total of 86 cases involving 30 different plant species were identified. The species most frequently involved were ruda (Ruta chalepensis/graveolens), cola de quirquincho (Lycopodium saururus), parsley (Petroselinum hortense), and an over-the-counter herbal product named Carachipita. The components of Carachipita are pennyroyal (Mentha pulegium), yerba de la perdiz (Margiricarpus pinnatus), oregano (Origanum vulgare), and guaycuri (Statice brasiliensis). Abortion occurred in 23 cases after the ingestion of parsley, ruda, Carachipita, celery, Cedron, francisco alvarez, floripon, espina colorada. Out of the 23 cases, 15 involved the only the ingestion of plants, 4 cases used injected drugs (presumably hormones), and in 4 cases there was associated self-inflicted instrumental manipulation. Multiple organ system failure occurred in those patients who had ingested ruda (alone or in combination with parsley or fennel), Carachipita, arnica, or bardana. Deaths occurred in one case of Carachipita ingestion and in 4 cases of ruda ingestion (2 cases of ruda alone, 2 cases of ruda with parsley and fennel). Self-inflicted instrumental manipulations were found in 4 of the patients with multiple organ system failure and in one of those who died. The results of this report are not conclusive, but it appears that the ingestion of plants to induce abortion involves the risk of severe morbidity and mortality.

Methods: T-suppressor cell activities of 56 pregnant women with H A history were tested with method of short life T-suppressor cell activity (MTT method) during early pregnancy, and were followed-up in middle and late pregna ncy in 20 cases of them. All the 56 patients YXATG treatment. Groups of normal early pregnant, normal non-pregnant women and those non-pregnant but with history of habitual abortion were involv ed in this study as control. Results: T-suppressor cell activity in early pregnancy was lowe r than that of middle and late pregnancy (P<0.01, P<0.001) and also low er than that of the control groups (P<0.01, P<0.001). The successful rate of fetus preservation of YXATG was 98.2%, and 98.0% of the cases got normal delivery. Conclusion: Low T-suppressor cell activity might be the immunologic etiology of HA. The fetus preservative effect of YXATG might be due to its regulatory effect on T-suppressor cell activity.

    With the possibility of the Supreme Court overturning the landmark Roe v. Wade (1973) case legalizing abortion, a review of abortion practices pre-Roe is instructive. Abortion became criminalized in the US around 1870, yet many abortions were performed. While estimates for the yearly number of pre-Roe illegal abortions roughly resemble today's number of legal abortions, the difference between legal and illegal abortion rests in the difference between the large number of women who died or were injured then, and the very few women who now die from illegal abortions. Along with the self-induced abortion, different categories of providers performed illegal abortions: physicians, nonphysicians, nurses, midwives, and lay people; all with varying skill, experience, and motives. While there were "butchers" and sexual exploiters, there were also competent, beloved physicians. There were the financially motivated physicians providing abortions full time, and the occasional providers acting with a sense of conscience, risking successful practices and jail. Within this "conscience" group of 44 interviewees gathered through personal networks, ads, etc., abortions were: performed outside of hospitals, reducing the risk of discovery, but creating greater medical risks; begun outside of a hospital with the intrusion into the uterus of an object, provoking a "spontaneous abortion" (miscarriage) needing completion by D and C (dilation and curettage) within a hospital, but only a limited number of such patients could be referred before arousing suspicion; and in a hospital under disguised circumstances, a very tricky undertaking with severe limitations, available only a few times before risking detection. Avoidance and lack of training by today's physicians and the well organized antiabortion groups will undoubtedly make illegal abortions even more difficult to engage in than the pre-Roe days.

    Strong stimuli applied to the tailfan of the crayfish Procambarus clarkii evoked lateral giant interneurone (LG)-mediated tailflips. When the sensory stimulus was applied repeatedly, the response of the LG habituated until it failed to give rise to a spike. We found that this LG-flip habituation was dependent on social status. With a short interstimulus interval of 5 s, the rate of habituation of the LG in both socially dominant and subordinate crayfish was lower than that in socially isolated animals. By contrast, with a long interstimulus interval of 60 s, the rate of habituation of subordinate animals was lower than that of both socially isolated and dominant animals. The excitability of the LGs following habituation was also dependent on social status. Following habituation, the spike response of LGs recovered within several minutes; however, they showed significant depression with a decrease in excitability. With a 5 or 60 s interstimulus interval, subordinate animals showed longer delays of depression compared with dominant animals. A decrease in the rate of habituation and a delay of depression in subordinate crayfish would be advantageous for maintaining an active escape response to evade repeated attacks of dominant animals and a reduced learning ability to adapt to social status.

    Full Text Available Abstract Background Habitual snoring, a prominent symptom of sleep-disordered breathing, is an important indicator for a number of health problems in children. Compared to adults, large epidemiological studies on childhood habitual snoring and associated predisposing factors are extremely scarce. The present study aimed to assess the prevalence and associated factors of habitual snoring among Chinese school-aged children. Methods A random sample of 20,152 children aged 5.08 to 11.99 years old participated in a cross-sectional survey, which was conducted in eight cities of China. Parent-administrated questionnaires were used to collect information on children's snoring frequency and the possible correlates. Results The prevalence of habitual snoring was 12.0% (14.5% for boys vs. 9.5% for girls in our sampled children. Following factors were associated with an increased risk for habitual snoring: lower family income (adjusted odds ratio [OR] = 1.46, lower father's education (OR = 1.38 and 1.14 for middle school or under and high school of educational level, respectively, breastfeeding duration Conclusion The prevalence of habitual snoring in Chinese children was similar to that observed in other countries. The potential predisposing factors covered socioeconomic characteristics, environmental exposures, chronic health problems, and family susceptibility. Compared to socioeconomic status and family susceptibility, environmental exposures and chronic health problems had greater impact, indicating childhood habitual snoring could be partly prevented by health promotion and environmental intervention.

    2016-11-01

    Neural habituation allows familiar information to be ignored in favor of salient or novel stimuli. In contrast, failure to rapidly habituate likely reflects deficits in the ability to learn that an environment is predictable, familiar and safe. Differences in habituation rate may underlie individual differences in the tendency to approach or avoid novelty; however, many questions remain unanswered. Given the importance of adaptive social functioning, here we tested whether habituation differences to social stimuli are associated with differences in social fearfulness, a trait that ranges from low social fear-the adaptive tendency to approach novel social stimuli-to high social fear-the maladaptive tendency to avoid novel social stimuli. Higher social fearfulness was associated with slower habituation across regions of the social brain, including the hippocampus, amygdala, ventromedial prefrontal cortex, medial orbitofrontal cortex, fusiform face area, primary visual cortex, and extrastriate visual cortex. Interestingly, habituation differences were driven by sustained amygdala-visual cortex interactions, but not deficient amygdala-prefrontal cortex interactions. Together, these findings provide evidence that a failure to filter social stimuli is associated with a key social trait. In light of the link between social fear and dysfunction, individual differences in habituation may provide an important neurobiological marker for risk for psychiatric illness, such as social anxiety disorder.

    The habituation of the acoustic startle reflex (ASR) was examined concerning individual differences in sensitivity to punishment (PUN) and sensitivity to reward (REW), within the general framework of the reinforcement sensitivity theory (RST) of personality. Two hypotheses derived from the RST were evaluated: the separable subsystems hypothesis and the joint subsystems hypothesis. In addition, we examined the direction of the relationship of PUN and REW with the habituation of the ASR. A habituation segment of electromyography recordings of the orbicularis oculi was assessed with an unconditional latent curve model. In accordance with the RST hypotheses, the relationship of PUN and REW on the habituation process was assessed with two conditional latent curve models. There was higher support for the separable subsystems hypothesis. In addition, PUN and REW related with the habituation trajectory of the ASR in the expected directions. Higher levels of PUN and lower levels of REW related with a slower habituation of the ASR, whereas lower levels of PUN and higher levels of REW related with a faster habituation of the ASR.

    The purpose of this study was to examine differences in habituation to heat and cold pain in women with fibromyalgia (FM; n=33) and in women who were healthy controls (HC; n=44). Quantitative sensory testing (QST) was used to assess pain thresholds during five consecutive trials of ascending heat and descending cold stimulation. Anxiety, depression, fatigue, and pain during the previous week were assessed using self-report measures. The overall hypotheses were that there would be differences between groups in pain thresholds and in the rate of habituation to heat and cold pain stimuli. Multilevel modeling was used to test the hypotheses. There were large overall differences in pain thresholds, with the FM group showing greater sensitivity to heat and cold pain stimuli compared with the HC group. While habituation occurred in both of the groups for heat pain, the HC group had stronger habituation across trials than the FM group. Conversely, while the HC group habituated to cold pain stimuli, the FM group showed sensitization and had decreased cold pain thresholds across trials (they felt cold pain at higher temperatures). In addition, anxiety, depression, fatigue, and pain were related to decreased heat and cold pain thresholds in the overall sample. However, when group was controlled, none of these variables were related to thresholds or rates of habituation or sensitization. The differences between women with FM and healthy women in habituation and sensitization may have important implications for the etiology, diagnosis, and treatment of FM and other chronic pain conditions.

  1. Gynecologists and the abortion issue in Serbia

    Full Text Available Traditional inefficient contraception, incorporated to a large extent in the system of values, has become a natural part of sexual relations in Serbia and represents a rational preventive choice from the individual standpoint. However, when pregnancy is unwanted or cannot be accepted out of any reasons abortion is used as a resort. For this reason there is a long history of a large number of abortions in Serbia. Research findings in our country identify the following, as the most important factors for not accepting modern values in this sphere: traditional contraception and abortion have a firm social confirmation; there is a trans-generational transfer of psychological resistance towards the use of combined oral contraception pills and intrauterine devices; sexual education has never become a natural way of growing up in the family, nor is a constituent part of school programs and that distinct obstacles of various nature exist regarding contraception availability. A developed network of various types of family planning counseling is an important determinant of the accessibility of contraceptive means and methods. There are, however, numerous conditions which have to be fulfilled in order for the contraception counseling services to function properly. Among them, motivated personnel who acquired general and specific knowledge for work in this field are an especially important prerequisite. This theoretical assumption opens the question -whether gynecologists represent an important factor of slow transition of birth control in Serbia? We searched for the answer in the research analyses obtained through two in-depth surveys which either had to do with this theme or tried to determine the knowledge, attitude and practice of gynecologists. The first research regarding the determination of the causes for a large number of abortions in our country, was directed towards women who decided on abortion. Gynecologists were the target group in the second

    The transition from goal-directed actions to habitual ethanol seeking models the development of addictive behavior that characterizes alcohol use disorders. The progression to habitual ethanol-seeking behavior occurs more rapidly than for natural rewards, suggesting that ethanol may act on habit circuit to drive the loss of behavioral flexibility. This review will highlight recent research that has focused on the formation and expression of habitual ethanol seeking, and the commonalities and distinctions between ethanol and natural reward-seeking habits, with the goal of highlighting important, understudied research areas that we believe will lead toward the development of novel treatment and prevention strategies for uncontrolled drinking.

    Nearly 40 years after enactment of the Medical Termination of Pregnancy Act of 1971, unsafe abortion continues to be a neglected women's health issue in India. This prospective study of women presenting for post-abortion care in 10 selected hospitals in Madhya Pradesh, India, aimed to understand the incidence, types and severity of post-abortion complications, probable causes of complications and consequences to women in terms of hospitalisation and incurred costs. Among 1565 women presenting for induced abortion-related services between July and November 2007, 381 women with post-abortion complications consented to participate. Data reveal a high prevalence of post-abortion complications (29%). Approximately half of women originally attempted to induce abortion at home using medication, home-made concoctions or traditional methods. Ninety percent sought care from either qualified (37%) or unqualified providers. More than half of the women were hospitalised as a result of post-abortion complications. This study suggests that supporting access to safely induced abortion services and improving community awareness on legal aspects, safe methods and approved providers are all necessary to reduce morbidity associated with unsafe abortion.

    Full Text Available Prostitutes are vulnerable to unplanned pregnancies and abortions. In Brazil, abortion is a crime and there is no data about unsafe abortions for this population. The study describes how prostitutes perform illegal abortions and the health consequences thereof. Semi-structured interviews with 39 prostitutes from three cities in Brazil with previous induced abortion experience were conducted. Sixty-six abortions, with between one and eight occurrences per woman, were recorded. The majority of the cases resulted from sexual activity with clients. The inconsistent use of condoms with regular clients and the consumption of alcohol during work were indicated as the main causes of unplanned pregnancies. The main method to perform abortion was the intravaginal and oral use of misoprostol, acquired in pharmacies or on the black market. Invasive measures were less frequently reported, however with more serious health complications. The fear of complaint to the police meant that most women do not inform the health team regarding induced abortion. The majority of prostitutes aborted with the use of illegally-acquired misoprostol, ending abortion in a public hospital with infection and hemorrhagic complications. The data indicate the need for a public policy focusing on the reproductive health of prostitutes.

    In view of the lack of information regarding abortion attitudes in Mexico, an abortion opinion survey was conducted in Mexico City among 387 women and 338 men. Respondents were asked if they agreed with a woman's abortion decision under seven different circumstances. Affirmative responses were analyzed by respondents' sociodemographic and reproductive health characteristics and a scale was created to measure respondents' overall attitudes toward abortion. Greatest support was expressed for a woman's right to an abortion, and to abortion in cases of fetal defect, threat to the mother's life, and rape. On the attitudinal scale, however, respondents generally disapproved abortion. Male respondents were more likely than female respondents to support a woman's abortion decision. Males in union, females not in union, respondents over thirty years of age, those with more than primary school education, those with fewer pregnancies, those with no history of child mortality, and those with a history of or experience with abortion, were also more likely to support an abortion decision.

    The psychological impact of abortion on the women undergoing the procedure is well researched, but little is known about the potential psychological impact on nurses working in abortion care. The proportion of medical abortions in the UK is rising compared to surgical abortions. A recent research study found that being more directly involved in the procedure places more emotional demands on the nurses. This emotional labour required by nurses working in abortion care may increase their stress levels. This paper examines the potential increase in stress in nurses caused by medical abortions. A model of stress comprising stressors, moderators and stress outcomes was used as a framework for this examination. Research on abortion and mental health nursing was applied to managing stress in abortion care; this included coping mechanisms, prevention and intervention strategies. This showed that stress, burnout and coping are important issues in abortion care. On this basis, recommendations for practice have been formulated to inform practice for nurses and managers in abortion care.

  8. Goal-directed, habitual and Pavlovian prosocial behavior

    2015-05-01

    Full Text Available Although prosocial behaviors have been widely studied across disciplines, the mechanisms underlying them are not fully understood. Evidence from psychology, biology and economics suggests that prosocial behaviors can be driven by a variety of seemingly opposing factors: altruism or egoism, intuition or deliberation, inborn instincts or learned dispositions, and utility derived from actions or their outcomes. Here we propose a framework inspired by research on reinforcement learning and decision making that links these processes and explains characteristics of prosocial behaviors in different contexts. More specifically, we suggest that prosocial behaviors inherit features of up to three decision-making systems employed to choose between self- and other- regarding acts: a goal-directed system that selects actions based on their predicted consequences, a habitual system that selects actions based on their reinforcement history, and a Pavlovian system that emits reflexive responses based on evolutionarily prescribed priors. This framework, initially described in the field of cognitive neuroscience and machine learning, provides insight into the potential neural circuits and computations shaping prosocial behaviors. Furthermore, it identifies specific conditions in which each of these three systems should dominate and promote other- or self- regarding behavior.

    The aim of this study was to examine the immediate effects of barefoot (BF) running on lower limb kinematics and muscle activity in a group of habitually shod runners. Ten male runners with no prior BF or minimalist running experience performed 1-min bouts of treadmill running at 3 velocities in both shod and BF conditions. 2D video data were recorded in order to quantify ankle, knee and hip kinematics. Synchronous kinetic data were recorded from a force plate supporting the treadmill in order to quantify spatiotemporal variables. EMG data were collected from 6 lower limb muscles, quantifying recruitment patterns during discrete phases of the gait cycle. BF running resulted in significantly higher stride frequency and shorter ground contact times (P < .001). Additionally, BF running significantly reduced knee and hip range of motion but increased ankle range of motion during the absorptive phase of the stance. Alterations in ankle kinematics during BF running resulted from increased pre-activation of the medial (P < .05) and lateral (P < .01) gastrocnemius in addition to reductions in pre-activation of the tibialis anterior (P < .05). The results highlight that recruitment patterns and kinematics can change in as little as 30-s of BF running in individuals with no previous BF running experience.

    Full Text Available Johanna M GeleijnseDivision of Human Nutrition, Wageningen University, The NetherlandsAbstract: This paper summarizes the current epidemiological evidence on coffee consumption in relation to blood pressure (BP and risk of hypertension. Data from crosssectional studies suggest an inverse linear or U-shaped association of habitual coffee use with BP in different populations. Prospective studies suggest a protective effect of high coffee intake (4 or more cups per day against hypertension, mainly in women. Furthermore, the risk of hypertension may be lower in coffee abstainers. Randomized controlled trials, which are mostly of short duration (1–12 weeks, have shown that coffee intake around 5 cups per day causes a small elevation in BP (∼2/1 mmHg when compared to abstinence or use of decaffeinated coffee. With regard to underlying biological mechanisms, most research has been devoted to BP-raising effects of caffeine. However, there are many other substances in coffee, such as polyphenols, soluble fi bre and potassium, which could exert a beneficial effect in the cardiovascular system. Although the precise nature of the relation between coffee and BP is still unclear, most evidence suggests that regular intake of caffeinated coffee does not increase the risk of hypertension.

    Organizational change is a particularly emotional event for those being confronted with it. Anger is a frequently experienced emotion under these conditions. This study analyses the influence of employees' habitual anger reactions on their reported behavior during organizational change. It was explored whether anger reactions conducive to recovering or increasing individual well-being will enhance the likelihood of functional change behavior. Dysfunctional regulation strategies in terms of individual well-being are expected to decrease the likelihood of functional change behavior-mediated by the commitment to change. Four hundred and twelve employees of different organizations in Luxembourg undergoing organizational change participated in the study. Findings indicate that the anger regulation strategy venting, and humor increase the likelihood of deviant resistance to change. Downplaying the incident's negative impact and feedback increase the likelihood of active support for change. The mediating effect of commitment to change has been found for humor and submission. The empirical findings suggest that a differentiated conceptualization of resistance to change is required. Specific implications for practical change management and for future research are discussed.

    Item order can bias learners' study decisions and undermine the use of more effective allocation strategies, such as allocating study time to items in one's region of proximal learning. In two experiments, we evaluated whether the influence of item order on study decisions reflects habitual responding based on a reading bias. We manipulated the order in which relatively easy, moderately difficult, and difficult items were presented from left to right on a computer screen and examined selection preference as a function of item order and item difficulty. Experiment 1a was conducted with native Arabic readers and in Arabic, and Experiment 1b was conducted with native English readers and in English. Students from both cultures prioritized items for study in the reading order of their native language: Arabic readers selected items for study in a right-to-left fashion, whereas English readers largely selected items from left to right. In Experiment 2, native English readers completed the same task as participants in Experiment 1b, but for some participants, lines of text were rotated upside down to encourage them to read from right to left. Participants who read upside-down text were more likely to first select items on the right side of an array than were participants who studied right-side-up text. These results indicate that reading habits can bias learners' study decisions and can undermine agenda-based regulation.

  13. Betting on Illusory Patterns: Probability Matching in Habitual Gamblers.

    Why do people gamble? A large body of research suggests that cognitive distortions play an important role in pathological gambling. Many of these distortions are specific cases of a more general misperception of randomness, specifically of an illusory perception of patterns in random sequences. In this article, we provide further evidence for the assumption that gamblers are particularly prone to perceiving illusory patterns. In particular, we compared habitual gamblers to a matched sample of community members with regard to how much they exhibit the choice anomaly 'probability matching'. Probability matching describes the tendency to match response proportions to outcome probabilities when predicting binary outcomes. It leads to a lower expected accuracy than the maximizing strategy of predicting the most likely event on each trial. Previous research has shown that an illusory perception of patterns in random sequences fuels probability matching. So does impulsivity, which is also reported to be higher in gamblers. We therefore hypothesized that gamblers will exhibit more probability matching than non-gamblers, which was confirmed in a controlled laboratory experiment. Additionally, gamblers scored much lower than community members on the cognitive reflection task, which indicates higher impulsivity. This difference could account for the difference in probability matching between the samples. These results suggest that gamblers are more willing to bet impulsively on perceived illusory patterns.

    Within the Swiss legal code, somatic and psychiatric indications for interruption of pregnancy are very well indicated and codified. These days, however, only 8% of indications for abortion are based on purely medical reasons; the great majority of indications are "modern", a clear manifestation of a slipping away from classical indications toward a much more liberal intervention which often has nothing to do with the corporal integrity of the mother, but with that of the child, or which simply takes into consideration the future quality of life of everybody involved. This evolution is a reflection of the new role of women in society, and also the result of the recent progresses of the science of neonatology. Such enlarged indications for abortion are accepted by most doctors concerned with these problems, and they include such different reasons as IUD failure, hormonal contraception failure, very young or too old age, exposure to X-rays, divorce and exposure to chemotherapy.

    The psychodiagnostic indication for abortion was investigated by means of the MMPI in 251 women with unwanted pregnancy. The results showed: 1. that, independently of the MMPI, positive indications exhibited more obvious psychopathological distrubance than the negative indications; 2. that women with negative indications where in some ways psychologically different from women with wanted pregnancy; 3. that after abortion women with positive indication no longer differed from a group of women with wanted pregnancy, so that the former could be identified as psychologically well adjusted; and 4. comparison between women with unwanted pregnancy and a group of neurotic women showed that both groups are phenomenologically very similar although women with unwanted pregnancy should be diagnosed as "reactive". The results are presented without comment as a basis for the medical and political debate now in progress.

    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.

    A reduced habituation of averaged laser-evoked potential (LEP) amplitudes was previously found in migraine patients. The aim of the present study was to assess the habituation of single LEP responses and pain sensation during the interictal phase in migraine patients. Fourteen migraine patients were compared with ten control subjects. The pain stimulus was laser pulses, generated by CO2 laser, delivered to right supraorbital zone. Patients were evaluated during attack-free conditions. The LEP habituation was studied by measuring the changes of LEP amplitudes across and within three consecutive repetitions of 21 non-averaged trials. In migraine patients the N2-P2 wave amplitudes did not show a tendency toward habituation across and, above all, within the three repetitions. Anomalous behaviour of nociceptive cortex during the interictal phase of migraine may predispose patients to headache occurrence and persistence.

    Objective Research shows that slower habituation of salivary responses to food stimuli is related to greater energy intake and that obese (Ob) individuals habituate slower than those of normal weight (NW). No study has examined habituation rates in weight loss maintainers (WLMs) who have reduced from obese to normal weight, relative to those who are Ob or NW. Design Salivation to two baseline water trials and 10 lemon-flavored lollipop trials were studied in 14 WLMs, 15 Ob and 18 NW individuals comparable in age, gender and ethnicity. Linear mixed models were used to compare WLMs with Ob and NW groups. Results Salivation in the WLM and NW groups decreased significantly (for both P obesity, and show quicker habituation than those who are currently obese. These results suggest that physiological responses to food may ‘normalize’ with successful weight loss maintenance. PMID:20010900

    The habituation to sensory stimuli of different modalities is reduced in migraine patients. However, the habituation to pain has never been evaluated. Our aim was to assess the nociceptive pathway function and the habituation to experimental pain in patients with migraine. Scalp potentials were evoked by CO(2) laser stimulation (laser evoked potentials, LEPs) of the hand and facial skin in 24 patients with migraine without aura (MO), 19 patients with chronic tension-type headache (CTTH), and 28 control subjects (CS). The habituation was studied by measuring the changes of LEP amplitudes across three consecutive repetitions of 30 trials each (the repetitions lasted 5 min and were separated by 5-min intervals). The slope of the regression line between LEP amplitude and number of repetitions was taken as an index of habituation. The LEPs consisted of middle-latency, low-amplitude responses (N1, contralateral temporal region, and P1, frontal region) followed by a late, high-amplitude, negative-positive complex (N2/P2, vertex). The latency and amplitude of these responses were similar in both patients and controls. While CS and CTTH patients showed a significant habituation of the N2/P2 response, in MO patients this LEP component did not develop any habituation at all after face stimulation and showed a significantly lower habituation than in CS after hand stimulation. The habituation index of the vertex N2/P2 complex exceeded the normal limits in 13 out of the 24 MO patients and in none of the 19 CTTH patients (P<0.0001; Fisher's exact test). Moreover, while the N1-P1 amplitude showed a significant habituation in CS after hand stimulation, it did not change across repetitions in MO patients. In conclusion, no functional impairment of the nociceptive pathways, including the trigeminal pathways, was found in either MO or CTTH patients. But patients with migraine had a reduced habituation, which probably reflects an abnormal excitability of the cortical areas involved in

    We habituated the dominant time constant of the horizontal vestibuloocular reflex (VOR) of rhesus and cynomolgus monkeys by repeated testing with steps of velocity about a vertical axis and adapted the gain of the VOR by altering visual input with magnifying and reducing lenses. After baseline values were established, the nodulus and ventral uvula of the vestibulocerebellum were ablated in two monkeys, and the effects of nodulouvulectomy and flocculectomy on VOR gain adaptation and habituation were compared. The VOR time constant decreased with repeated testing, rapidly at first and more slowly thereafter. The gain of the VOR was unaffected. Massed trials were more effective than distributed trials in producing habituation. Regardless of the schedule of testing, the VOR time constant never fell below the time constant of the semicircular canals (approximately 5 s). This finding indicates that only the slow component of the vestibular response, the component produced by velocity storage, was habituated. In agreement with this, the time constant of optokinetic after-nystagmus (OKAN) was habituated concurrently with the VOR. Average values for VOR habituation were obtained on a per session basis for six animals. The VOR gain was adapted by natural head movements in partially habituated monkeys while they wore x 2.2 magnifying or x 0.5 reducing lenses. Adaptation occurred rapidly and reached about +/- 30%, similar to values obtained using forced rotation. VOR gain adaptation did not cause additional habituation of the time constant. When the VOR gain was reduced in animals with a long VOR time constant, there were overshoots in eye velocity that peaked at about 6-8 s after the onset or end of constant-velocity rotation. These overshoots occurred at times when the velocity storage integrator would have been maximally activated by semicircular canal input. Since the activity generated in the canals is not altered by visual adaptation, this finding indicates that the gain

    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.

    This paper investigated the attitude toward abortion and other reproductive health services of first- and second-year medical students at the Seattle campus of the University of Washington, a large regional primary care-oriented medical school, in 1996-97. A total of 219 (76.6%) students responded. The majority of the students support the availability of a broad range of reproductive health services including abortion; 58.1% felt that first-trimester abortions should be available to patients under most circumstances. Of the 43.4% of students who anticipated a career in family practice, most expected to provide abortions in their future practices. Moreover, older students and women were more likely to support the provision of abortion services. This study concludes that despite the continuing pressure on abortion providers, most first- and second-year medical students at a fairly state-supported medical school intend to incorporate this procedure into their future practices.

    Full Text Available BACKGROUND: Free radicals and antioxidant exist in balance under normal condition. In prooxidant condition, excessive free radicals can initiate a state of oxidative stress (OS followed by capillary endothelial cell damage, a process involved in the pathophysiology of abortion. CONTENT: Abortion is a common complication of pregnancy and occurs in 25% of women. Many factors can cause abortion including fetal factor, implantation process and hormonal status. Combination those factors with OS influence the entire reproductive life of a woman. Antioxidant can neutralize free radicals and used to reduce OS especially in recurrent abortion. SUMMARY: Antioxidant therapy is a very interesting field in abortion especially used as prevention approach mainly caused by the high cost of infertility treatment methods. KEYWORDS: free radical, antioxidant, abortion.

    The Government of Ghana has taken important steps to mitigate the impact of unsafe abortion. However, the expected decline in maternal deaths is yet to be realized. This literature review aims to present findings from empirical research directly related to abortion provision in Ghana and identify gaps for future research. A total of four (4) databases were searched with the keywords "Ghana and abortion" and hand review of reference lists was conducted. All abstracts were reviewed. The final include sample was 39 articles. Abortion-related complications represent a large component of admissions to gynecological wards in hospitals in Ghana as well as a large contributor to maternal mortality. Almost half of the included studies were hospital-based, mainly chart reviews. This review has identified gaps in the literature including: interviewing women who have sought unsafe abortions and with healthcare providers who may act as gatekeepers to women wishing to access safe abortion services.

    Diagnostic findings in 218 aborted bovine foetuses are reported. The materials were examined in a matched case-control study of 69 Danish dairy herds with a sudden increase in the number of abortions and a corresponding 69 control herds. Foetuses aborted during the subsequent 6-month period were...... examined to identify the cause of abortion if possible. A total of 186 specimens were submitted from case herds and 32 from control herds. A likely cause of abortion was diagnosed in 73 foetuses. The most common cause was bovine viral diarrhoea virus (BVDV: 13%) followed by Neospora caninum infection (10......%), mycosis (5%) and Bacillus licheniformis infection (4%). Foetal and/or placental lesions were found in a further 27 cases. Only BVDV infection and neosporosis were diagnosed in more than one foetus per herd and only protozoal associated abortions occurred significantly more frequently in the case, rather...

    BACKGROUND: Few studies have examined smoking prior to pregnancy and the occurrence of spontaneous abortion, as most studies have addressed the risk of spontaneous abortion in relation to smoking during pregnancy. However, results are not entirely consistent. The aim of the present study...... was to assess the risk of spontaneous abortion considering smoking prior to pregnancy. METHODS: We performed a nested case-control study using prospective data from a population-based cohort comprising 11,088 women aged 20-29 years. From this cohort, women who experienced either a spontaneous abortion (n=343......) or who gave birth (n=1,578) during follow-up were selected. Associations between self-reported smoking at enrollment and subsequent spontaneous abortion were analyzed by means of multiple logistic regression. RESULTS: The risk of spontaneous abortion in relation to pre-pregnancy smoking showed a clear...

    OBJECTIVE: To investigate how Danish citizens evaluate four moral claims related to abortion issues, regarding the moral status of the fetus, autonomy, harm and possible negative consequences of allowing abortion and to explore the association between moral beliefs and attitudes towards abortion...... to at least one moral claim. Two hundred and fifty-eight responded to all four claims without using the option 'neither agree nor disagree' and were classified as 'morally engaged responders'. A majority of these had a pro-abortion moral. The general relationship between moral beliefs and attitudes towards...... abortion was morally sound. Being 'morally engaged' did not increase the likelihood of reaching moral judgement on whether requests for abortion should be permitted. Education, religion and parenthood were statistically associated with the investigated issues. DISCUSSION: The direction of causality...

    STUDY QUESTION: 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? SUMMARY ANSWER: 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.

    1991-01-01

    Sixty-three women students of the health care professions were surveyed about their abortion and post-abortion experiences, feelings, and attitudes. Variables predictive of short- and long-term adjustment, belief in the wisdom of the choice, and right to choose were analysed, as were effects on emotional and attitudinal responses of passage of time and pressure to abort. Most reported mild, transient, short-term negative effects, and generally benign long-term effects. Implications of the findings are discussed.

    Abortion in Brazil provides public health impacts, mainly due to the high rate of maternal morbidity and mortality, because it most often occurs in an illegal practice and / or unsafe, because of the illegality of abortion in certain situations in the country. Therefore, it is an issue that refers to the various reflections, such as legal, moral, cultural, socio-economic and bioethical. Given the above, the study aims to address about abortion in Brazil and the impacts of illegality in pu...

    During 1995-96, 17 of 50 US states used their own resources, either voluntarily or under state court order, to pay for all or most abortions for low-income women. Alaska, Maryland, New York, and Washington are the only states to voluntarily pay for these abortions. Anti-choice legislators in California, Illinois, New York, and West Virginia tried unsuccessfully to cut funding for these abortions. Arkansas is the only state to circumvent direct payment for abortions for low-income women. Alabama, Mississippi, and South Dakota still are not complying with the court order but remain in the Medicaid program. Massachusetts has passed legislation to allow health insurance to cover abortions for state and city employees, thereby undoing a 17-year ban on the use of public funds for abortions for employees or their spouses. On the other hand, Virginia's governor has unilaterally, via an executive order, eliminated health insurance coverage for most abortions for state employees and their dependents. Anti-choice legislators have shepherded legislation that prohibit private insurance coverage for abortion unless women pay an extra premium in Idaho, Kentucky, Missouri, and North Dakota. Legislators in Illinois and Minnesota have passed state subsidized health care reform programs that exclude abortion from coverage except when the mother's life is endangered. There appears to be a loophole in the MinnesotaCare program that allows women to obtain state-financed abortions for other reasons, so antifunding lawmakers will introduce a bill in 1997 to close the loophole. The loophole is a result of a conflict between state and federal laws as a result of a 1995 federal waiver granted to Minnesota. The waiver allows pregnant women who earn up to 275% of the federal poverty level to be eligible for either MinnesotaCare or Medicaid. Abortion-rights legislators find MinnesotaCare's exclusion of abortion coverage to be a violation of the court order. They plan to submit a bill in 1997 to

    The development of drug-seeking habits is implicated in the transition from recreational drug use to addiction. Using a drug seeking/taking chained schedule of intravenous cocaine self-administration and reward devaluation methods in rats, the present studies examined whether drug seeking that is initially goal-directed becomes habitual after prolonged drug seeking and taking. Devaluation of the outcome of the drug seeking link (i.e., the drug taking link of the chained schedule) by extinction significantly decreased drug seeking indicating that behavior is goal-directed rather than habitual. With, however, more prolonged drug experience, animals transitioned to habitual cocaine seeking. Thus, in these animals, cocaine seeking was insensitive to outcome devaluation. Moreover, when the dorsolateral striatum, an area implicated in habit learning, was transiently inactivated, outcome devaluation was effective in decreasing drug seeking indicating that responding was no longer habitual but had reverted to control by the goal-directed system. These studies provide direct evidence that cocaine seeking becomes habitual with prolonged drug experience and describe a rodent model with which to study the neural mechanisms underlying the transition from goal-directed to habitual drug seeking.

    Habituation is considered one of the most basic mechanisms of learning. Habituation deficit to several sensory stimulations has been defined as a trait of migraine brain and also observed in other disorders. On the other hand, analytic information processing style is characterized by the habit of continually evaluating stimuli and it has been associated with migraine. We investigated a possible correlation between lack of habituation of evoked visual potentials and analytic cognitive style in healthy subjects. According to Sternberg-Wagner self-assessment inventory, 15 healthy volunteers (HV) with high analytic score and 15 HV with high global score were recruited. Both groups underwent visual evoked potentials recordings after psychological evaluation. We observed significant lack of habituation in analytical individuals compared to global group. In conclusion, a reduced habituation of visual evoked potentials has been observed in analytic subjects. Our results suggest that further research should be undertaken regarding the relationship between analytic cognitive style and lack of habituation in both physiological and pathophysiological conditions.

    Conclusion: These findings highlight the need to improve rural women's knowledge of fertility and contraception. Media and service providers should use every possible opportunity to educate women regarding the legal status of abortion and to promote contraceptive usage by creating awareness regarding safety and free availability of various contraceptives thereby clearing misconceptions regarding contraception. There is a need to educate rural women that use of a regular contraceptive method is better than undergoing repeated abortions. [Int J Reprod Contracept Obstet Gynecol 2015; 4(4.000: 1153-1157

    In 2008, the Victorian Parliament enacted the Abortion Law Reform Act 2008 (Vic) and amended the Crimes Act 1958 (Vic) to decriminalise terminations of pregnancy while making it a criminal offence for unqualified persons to carry out such procedures. The reform legislation has imposed a civil regulatory regime on the management of abortions, and has stipulated particular statutory duties of care for registered qualified health care practitioners who have conscientious objections to terminations of pregnancy. The background to, and the structure of, this novel statutory regime is examined, with a focus on conscientious objection clauses and liability in the tort of negligence and the tort of breach of statutory duty.

In this study, 168 habitually unshod runners (90 males whose age, weight & height were 23±2.4 years, 66±7.1 kg & 1.68±0.13 m and 78 females whose age, weight & height were 22±1.8 years, 55±4.7 kg & 1.6±0.11 m (Indians and 196 shod runners (130 males whose age, weight & height were 24±2.6 years, 66±8.2 kg & 1.72±0.18 m and 66 females whose age, weight & height were 23±1.5 years, 54±5.6 kg & 1.62±0.15 m (Chinese participated in a foot scanning test using the easy-foot-scan (a three-dimensional foot scanning system to obtain 3D foot surface data and 2D footprint imaging. Foot length, foot width, hallux angle and minimal distance from hallux to second toe were calculated to analyze foot morphological differences. This study found that significant differences exist between groups (shod Chinese and unshod Indians for foot length (female p = 0.001, width (female p = 0.001, hallux angle (male and female p = 0.001 and the minimal distance (male and female p = 0.001 from hallux to second toe.

    The aim was to study mismatch negativity features and habituation during the interictal phase of migraine. In migraine patients, a strong negative correlation has been found between the initial amplitude of long latency auditory-evoked potentials and their amplitude increase during subsequent averaging. We studied 12 outpatients with a diagnosis of migraine without aura recorded in a headache-free interval and 10 gender- and age-matched healthy volunteers not suffering from any recurrent headache. The experiment consisted of two sequential blocks of 2000 stimulations, during which 1800 (90%) recordings for standard tones and 200 (10%) for target tones were selected for averaging. The latency of the N1 component was significantly increased in migraine patients in respect of controls in both the first and second repetitions; the MMN latency was increased in the second repetition. In the control group the MMN amplitude decreased on average by 3.2 +/- 1.4 microV in the second trial, whereas in migraine patients it showed a slight increase of 0.21 +/- 0.11 microV in the second repetition. The MMN latency relieved in the second trial was significantly correlated with the duration of illness in the migraine patients (Spearman correlation coefficient: 0.69; P < 0.05). The increases in N1 latency and MMN latency and amplitude, the latter correlated with duration of illness, seemed to be due to a reduced anticipatory effect of stimulus repetition in migraine patients. This suggests that such hypo-activity of automatic cortical processes, subtending the discrimination of acoustic stimuli, may be a basic abnormality in migraine, developing in the course of the disease.

    Full Text Available This study aimed to assess total energy expenditure (TEE and specific habitual physical activities in adolescent sprint athletes. Two methods used to estimate TEE, an activity diary (AD and SenseWear armband (SWA, were compared. Sixteen athletes (6 girls, 10 boys, mean age 16.5 ± 1.6 yr simultaneously wore a SWA and completed an AD and food diary during one week. Basal energy expenditure as given by the SWA when taken off was corrected for the appropriate MET value using the AD. TEE as estimated by the AD and SWA was comparable (3196 ± 590 kcal and 3012 ± 518 kcal, p = 0.113 without day-to-day variations in TEE and energy expended in activities of high intensity. Daily energy intake (2569 ± 508 kcal did not match TEE according to both the AD and SWA (respectively p < 0.001 and p = 0.007. Athletes were in a supine position for a longer time on weekend days than on week days and slept longer on Sundays. Athletes reported a longer time of high-intensive physical activities in the AD than registered by the SWA on 4 out of 7 days. In addition to specific sprint activities on 3 to 7 days per week, 11 out of 16 athletes actively commuted to school where they participated in sports once or twice per week. The AD and the SWA are comparable in the estimation of TEE, which appears realistic and sustainable. The SWA offers an appropriate and objective method in the assessment of TEE, sleeping and resting in adolescent athletes on the condition that detailed information is given for the times the armband is not worn. The AD offers activity specific information but relies on the motivation, compliance and subjectivity of the individual, especially considering high-intensive intermittent training

  3. Psychological correlates of habitual diet in healthy adults.

    Science.gov (United States)

    Stevenson, Richard J

    2017-01-01

    There are 3 motivations for studying the psychological correlates of habitual diet. First, diet is a major but modifiable cause of morbidity and mortality, and dietary interventions could be improved by knowing the psychological characteristics of consumers of healthy/unhealthy diets. Second, animal studies indicate that diet can impair cognition, stress responsiveness, and affective processing, but it is unclear whether this also happens in humans. Third, certain psychological traits are associated with obesity, but it is not known whether these precede and thus contribute to weight gain. Although many psychological correlates of diet have been identified, the literature is highly dispersed, and there has been no previous comprehensive narrative review. Organized here by psychological domain, studies linking diet with individual differences in perception, cognition, impulsivity, personality, affective processing, mental health, and attitudes, beliefs and values-in healthy adults-are reviewed. Although there is a growing literature on the psychological correlates of fruit/vegetable intake-the core of a healthy diet-consumers of unhealthy diets have characteristics that probably make them less responsive to education-based interventions. Diet may be a causal contributor to depression, and diet is consistently linked to impulsivity and certain personality traits. There are inconsistent and less explored links to perceptual, affective and cognitive processes, with several emerging parallels to the animal literature. Impulsivity and personality traits common to obese individuals also occur in lean consumers of unhealthy diets, suggesting these may contribute to weight gain. Diet-psychology correlates remain understudied even though this could significantly benefit human health. (PsycINFO Database Record

    A 6-month prospective study was conducted among 1739 women who underwent therapeutic abortion at Kandang Kerbau Hospital in Singapore to ascertain the aftereffects of abortion. Results of the study indicate that induced abortion has no observable bad effects on the mental health of the patients. In fact, somatic and psychiatric complaints were reduced and sexual adjustment increased 6 months postoperative. Those who were also sterilized at the time of the abortion showed a slightly lower rate of somatic symptom reduction than the rest of the group.

  6. José Barzelatto lecture: Vision on unsafe abortion.

    Faúndes, Anibal

    2010-04-01

    José Barzelatto first distinguished himself as a leader with a vision in his years as a medical student. Later, principally as Director of the Reproductive Health Program at the World Health Organization and of the Ford Foundation program for women's sexual and reproductive rights, he contributed immensely toward the recognition of women's sexual and reproductive rights as part of their basic human rights. José Barzelatto's vision on abortion reflects his drive to promote social justice and respect individual rights, respect diversity, and promote a social consensus for a peaceful society. He believed that the fetus has moral value and did not accept abortion as a method of fertility control, but understood that abortion is a social phenomenon that cannot be changed with legal or moral condemnation. He accepted that condemning women who abort does not prevent abortion, is unfair, and causes great human suffering at a high social cost. José proposed nine points to form the basis for an overlapping consensus on abortion, on which to base a practical consensus that would allow societies to reduce the number of abortions and minimize their consequences. If we can agree on all or most of those points we would achieve the common objectives of: fewer women confronting the dilemma of how to deal with an unwanted pregnancy; fewer induced abortions; and fewer women suffering the consequences of unsafe abortion.

    Full Text Available Background: The abortion incidence is influenced by many medical and socioeconomic factors. In some way, it indicates the wellbeing of the population, and the abortion statistics can show the ways to improve medical services and to raise the living standards of people. The objective of the study was to estimate the abortion incidence and to describe its current trends in the Republic of Sakha (Yakutia (the RS(Y. Materials and Methods: The study was designed as a population-based descriptive study, based on the results of a longitudinal analysis of national and regional reports of the Yakut healthcare services and an analysis of medical records describing 34,220 abortions among women living in all regions of Yakutia, which occurred between 2010 and 2014 and in the first 9 months of 2015. Results: The absolute number of abortions performed each year, the rate of abortions per 1,000 women of fertile age, and the rate of abortions per 100 deliveries declined (p<0.01 by about 37%, 32% and 37%, respectively, between 2006 and 2014. The rate of abortions per 1000 women of fertile age in the first 9 months of 2015 decreased by 1.3%, compared to the same period of 2014 (p=0.05. Though the number of abortions in primigravida women decreases every year, the percentage of them is still rather high, especially at the age of 20 to 24 and 15 to 19, accounting for approximately 2.4% of all abortions. The relative number of miscarriages before 12 weeks of pregnancy increased. Changes in the relative number of abortions performed between 12 to 21 weeks of pregnancy characterized by a decrease in the percentage of miscarriages from 2012 to 2015 and a dramatic increase in the percentage of therapeutic abortions. Conclusion: The revealed trends of the absolute number of abortions and the rates of occurrence in the RS(Y can be considered in total as favorable, but compared to the data obtained in Russia in total, the dynamics of these trends cannot be regarded as

    1998-09-01

    Despite its social, legal and medical importance, termination of pregnancy (TOP) (induced abortion) has rarely been the focus of psychosocial research. Of a total of 1329 women who consecutively attended the antenatal clinic of a general hospital in Japan, 635 were expecting their first baby. Of these 635 women, 103 (16.2%) had experienced TOP once previously (first aborters), while 47 (7.4%) had experienced TOP two or more times (repeated aborters). Discriminant function analysis was performed using psychosocial variables found to be significantly associated with either first abortion or repeated abortion in bivariate analyses. This revealed that both first and repeated aborters could be predicted by smoking habits and an unwanted current pregnancy while the repeated aborters appear to differ from first aborters in having a longer pre-marital dating period, non-arranged marriages, smoking habits, early maternal loss experience or a low level of maternal care during childhood. These findings suggest that both the frequency of abortion and its repetition have psychosocial origins.

    2016-09-12

    Conscientious objection to abortion - a clinician's refusal to perform abortions because of moral or religious beliefs - is a limited right, intended to protect clinicians' convictions while maintaining abortion access. This paper argues that conscientious objection policies and debates around the world generally do not take into account the social, political, and economic pressures that profoundly influence clinicians who must decide whether to claim objector status. Lack of clarity about abortion policies, high workload, low pay, and stigma towards abortion providers can discourage abortion provision. As the only legal way to refuse to provide abortions that are permitted by law, conscientious objection can become a safety valve for clinicians under pressure and may be claimed by clinicians who do not have moral or religious objections. Social factors including stigma also shape how stakeholders and policy-makers approach conscientious objection. To appropriately limit the scope of conscientious objection and make protection of conscience more meaningful, more information is needed about how conscientious objection is practised. Additionally, abortion trainings should include information about conscientious objection and its limits, reproductive rights, and creating an enabling environment for abortion provision. Policy-makers and all stakeholders should also focus on creating an enabling environment and reducing stigma.

    Full Text Available Unsafe abortions represent a preventable yet major cause of maternal mortality and morbidity in India. Intestinal perforation is a rare dreaded complication of unsafe abortion. It is commonly seen in countries in which abortions are performed by people without proper training and proper instruments. Bowel perforation occurs when the posterior vaginal wall or the uterine wall is perforated. The ileum and the sigmoid colon are the most commonly injured portion of the bowel. Here, we report a case of ileal perforation following induced unsafe abortion which was managed successfully. [Int J Reprod Contracept Obstet Gynecol 2016; 5(9.000: 3223-3225

    Politics, public discourse, and legislation restricting abortion has settled on a moderate orthodoxy: restrict abortion, but leave exceptions for pregnancies that result from rape and incest. I challenge that consensus and suggest it may be much harder to defend than those who support the compromise think. From both Pro-Life and Pro-Choice perspectives, there are good reasons to treat all abortions as equal.

As a result women were given access to safe pregnancy termination in first and second trimester. This study aims to describe socio-economic characteristics and contraceptive...... experience among women seeking abortion in Jimma, Ethiopia and to describe determinants of second trimester abortion. Methods: A cross-sectional study conducted October 2011 - April 2012 in Jimma Town, Ethiopia among women having safely induced abortion and women having unsafely induced abortion. In all 808...... safe abortion cases and 21 unsafe abortion cases were included in the study. Of the 829 abortions, 729 were first trimester and 100 were second trimester abortions. Bivariate and multivariate logistic regressions were used to determine risk factors associated with second trimester abortion...

  14. Effects of abortion legalization in Nepal, 2001-2010.

    Full Text Available 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

    "Abortion practiced under conditions of risk" is a phrase used to refer to illegal abortion. The phrase does not highlight the disappearance of risk when legislation changes. Rather, it calls attention to the fact that legal restrictions significantly increase dangers while failing to discourage women determined to terminate pregnancies. The International Planned Parenthood Federation defines abortion under conditions of risk as the use of nonoptimal technology, lack of counseling and services to orient the woman's decision and provide postabortion counseling, and the limitation of freedom to make the decision. The phrase encompasses concealment, illegality, corruption, and negligence. It is designed to impose a reproductive health perspective in response to an unresolved social conflict. Steps have been developed to improve the situation of women undergoing abortion even without a change in its legal status. Such steps include training and purchase of equipment for treatment of incomplete abortions and development of counseling and family planning services. The central difficulty of abortion induced in conditions of risk derives from the laws imposing the need for secrecy. In Mexico, the abortion decision belongs to the government and the society, while individual absorb the consequences of the practice of abortion. Public decision making about abortion is dominated by the concept that the female has an obligation to carry any pregnancy to term. Women who interfere with male descendency and practice a sexuality distinct from reproduction are made to pay a price in health and emotional balance. Resolution of the problem of abortion will require new concepts in terms of legal status, public health issues, and the rights of women. The problem becomes more pressing as abortion becomes more common in a country anxious to advance in the demographic transition. Only a commitment to the reproductive health of women and the full development of their rights as citizens will

    Without ambivalence, psychotherapy would be unnecessary; however there is a great deal of ambivalence about abortion so it is a therapy issue. In our society abortion decision are made in an ambivalent environment. Even when a woman makes a free decision to have a legal abortion, an emotional sequelae can ensue. This article reviews literature and relates professional experience about the psychological problems and treatment of women before and after having an abortion. A feeling of relief is the typical reaction to an abortion for the woman. The issues involved in the decision process are the woman's own health and happiness as well as that of her future family. The issues include medical and interpersonal ones and often present a moral crisis. Issues such as education, occupation, and relationships must be considered. Three major types of reactions seem to follow an abortion. The 1st is a positive feeling of happiness and relief. The 2nd and 3rd are negative, one being socially based guilt and the other being individually based guilt. Identifying abortion related issues in psychotherapy is not always easy, since they are no usually directly presented to the therapist. They often manifest themselves as symptoms of other problems. Research suggests that unmarried young women without children have a harder time resolving all the issues involved in making an abortion decision. One effective method of discovering emotional problems is to determine the reasons for delaying an abortion. If a woman is having problems making the decision is must be for an important reason. Just as important is the aftermath of the abortion. Attempts should be made to discover as much information about the procedure itself, the recovery time and any repercussions of the procedure. Neither research nor clinical experience has shown that abortion related psychotherapy is different than other forms of treatment. Griefwork, educational approaches, reviews of the decision making process and

    The isolation and identification of a chlamydial agent from an equine fetus is reported. The fetus was aborted by a mare with respiratory disease and fever in the 9th month of pregnancy. The serum of the mare was investigated by the compliment fixation test. Specific antibodies were detected for chlamydial antigen in a titer of > 1:40 and for equine herpes virus 1 antigen in a titer of 1:32. Pathological lesions were not found in the organs of the fetus. Chlamydiae were detected in the placenta by ELISA and subsequently isolated by cell culture. Using PCR technique the agent was identified as Chlamydophila psittaci.

    A 20-year-old female patient, 14 weeks pregnant, was admitted to hospital with anamnestic and clinical features of acute pyelonephritis. Clinical signs of septic abortion developed and after obstetric examination the therapy was changed to ampicillin, gentamicin and clindamycin. Campylobacter jejuni was isolated from blood cultures. Pathohistological findings confirmed diagnosis of purulent chorioamnionitis. After 2 weeks of ciprofloxacin administration the patient fully recovered. Campylobacter jejuni was not isolated from stool culture and no signs of acute enteritis were registered during the illness. Invasive forms of Campylobacter disease without enteritis are not unusual in immunocompromised hosts but they are restricted to C. fetus rather than C. jejuni isolates.

Due to its inherent dignity and value, human life must be protected from the moment of conception to that of natural death.

    This study aimed to assess total energy expenditure (TEE) and specific habitual physical activities in adolescent sprint athletes. Two methods used to estimate TEE, an activity diary (AD) and SenseWear armband (SWA), were compared. Sixteen athletes (6 girls, 10 boys, mean age 16.5 ± 1.6 yr) simultaneously wore a SWA and completed an AD and food diary during one week. Basal energy expenditure as given by the SWA when taken off was corrected for the appropriate MET value using the AD. TEE as estimated by the AD and SWA was comparable (3196 ± 590 kcal and 3012 ± 518 kcal, p = 0.113) without day-to-day variations in TEE and energy expended in activities of high intensity. Daily energy intake (2569 ± 508 kcal) did not match TEE according to both the AD and SWA (respectively p < 0.001 and p = 0.007). Athletes were in a supine position for a longer time on weekend days than on week days and slept longer on Sundays. Athletes reported a longer time of high-intensive physical activities in the AD than registered by the SWA on 4 out of 7 days. In addition to specific sprint activities on 3 to 7 days per week, 11 out of 16 athletes actively commuted to school where they participated in sports once or twice per week. The AD and the SWA are comparable in the estimation of TEE, which appears realistic and sustainable. The SWA offers an appropriate and objective method in the assessment of TEE, sleeping and resting in adolescent athletes on the condition that detailed information is given for the times the armband is not worn. The AD offers activity specific information but relies on the motivation, compliance and subjectivity of the individual, especially considering high-intensive intermittent training. Key pointsThe activity diary and Sensewear armband provide comparable estimates of TEE in adolescent sprint athletes.A high inter-individual variation was observed in time spent in high-intensity physical activities, advocating an individual based assessment when coaching

    The World Health Organization defines unsafe abortion as a procedure for terminating an unintended pregnancy carried out by people lacking the necessary skills or in an environment that does not conform to minimal medical standards, or both. The Programme of Action of the International Conference on Population and Development recommends that 'In circumstances where abortion is not against the law, such abortion should be safe'. However, millions of women still risk their lives by undergoing unsafe abortion even if they comply with the law. This is a serious violation of women's human rights, and obstetricians and gynaecologists have a fundamental role in breaking the administrative and procedural barriers to safe abortion. This chapter reviews the magnitude of the problem, its consequences for women's health, the barriers to access to safe abortion, including its legal status, the effect of the law on the rate and the consequences of abortion, the human rights implications and the current evidence on methods to perform safe abortion. This chapter concludes with an analysis of what can be done to change the current situation.

    1991-01-01

    The American Association of Pro-Life Obstetricians and Gynecologists is an 18 year old coalition of 960 doctors who refuse to perform abortions. In addition, they are committed to aggressively counseling women with unintended pregnancies to continue to full term. Today there are so many pressures on doctors not to perform abortions that they are turning away from the procedure. Financial, peer, an activist pressure all contribute to this change. A 1986 study found that 66% of gynecologists would not perform abortions. A National Abortion Federation study found that only 50% of training programs in medical schools offer abortion training. Further, the majority of these are optional so a great many doctors are leaving medical school with no training in abortion. Currently in 83% of the counties in the US there are no abortion providers. Utah has only 2, North and South Dakota each have 1. Women may still have the right to have abortions, but there is no Constitutional provision to ensure their doctor will be willing to perform one.

    2009-01-01

    The objective of this review is to identify and illustrate methodological issues in studies used to support claims that induced abortion results in an "abortion trauma syndrome" or a psychiatric disorder. After identifying key methodological issues to consider when evaluating such research, we illustrate these issues by critically examining recent empirical studies that are widely cited in legislative and judicial testimony in support of the existence of adverse psychiatric sequelae of induced abortion. Recent studies that have been used to assert a causal connection between abortion and subsequent mental disorders are marked by methodological problems that include, but not limited to: poor sample and comparison group selection; inadequate conceptualization and control of relevant variables; poor quality and lack of clinical significance of outcome measures; inappropriateness of statistical analyses; and errors of interpretation, including misattribution of causal effects. By way of contrast, we review some recent major studies that avoid these methodological errors. The most consistent predictor of mental disorders after abortion remains preexisting disorders, which, in turn, are strongly associated with exposure to sexual abuse and intimate violence. Educating researchers, clinicians, and policymakers how to appropriately assess the methodological quality of research about abortion outcomes is crucial. Further, methodologically sound research is needed to evaluate not only psychological outcomes of abortion, but also the impact of existing legislation and the effects of social attitudes and behaviors on women who have abortions.

    Cho, N H; Ahn, N

    1993-12-01

    Study results suggested that Korea's family planning program must shift to the promotion of a balanced sex ratio and prevention of induced abortion. The abortion rate increased markedly until the mid-1980s and then stabilized. The number of abortions almost equalled the number of live births. Retrospective data from the 1991 National Fertility and Family Health Survey of Korea were used to examine the determinants of pregnancy outcomes. The sample included 8475 pregnancies at parity 0, 7947 at parity 1, 5358 at parity 2, and 3437 at parity 3 or higher. An interesting finding was that families with 2 girls reported a very high number of spontaneous abortions since 1985: over 10% (41/389). The number of spontaneous abortions among families with 1-2 male children was only 3% (22/718). Among childless parents only 27% of pregnancies were aborted, while among one-child families 46% were aborted and among two-child families 81% were aborted. From before 1975 until after 1985, abortions among childless parents increased from 10% to 30%. This increase was accounted for by the increased number of premarital pregnancies, which were greater among middle and high school graduates. The abortion rate was high for pregnancies occurring at least 8 months before marriage and for pregnancies of more highly educated recent cohorts occurring earlier than 7 months before marriage. The probability of abortion was 3% for cohorts prior to 1974 with one son and 9% for the recent cohort (1985 and later). This shift may reflect a changed preference for smaller families and son preference. About 40% of pregnancies resulted in a live birth among families with 2 daughters in the most recent cohort. The probability of abortion was 33% higher among families with 2 boys in the earliest cohort than families without a son. The effect of education on pregnancy outcome varied with parity and time period. The abortion rate was higher among educated women, which meant less effective contraceptive

  15. Abortion and Catholic thought. The little-known history.

    Science.gov (United States)

    1996-01-01

    This article traces the history of the abortion policy of the Roman Catholic Church. The introductory section notes that the Church has consistently opposed abortion as evidence of sexual sin but has not always regarded it as homicide because Church teaching has never been definitive about the nature of the fetus. In addition, the prohibition of abortion has never been declared an infallible teaching. The chronology starts with a sketch of events in the first six Christian centuries when Christians sought ways to distinguish themselves from pagans who accepted contraception and abortion. During this period, Christians also decided that sexual pleasure was evil. Early Church leaders began the debate about when a fetus acquired a rational soul, and St. Augustine declared that abortion is not homicide but was a sin if it was intended to conceal fornication or adultery. During the period of 600-1500, illicit intercourse was deemed by the Irish Canons to be a greater sin than abortion, Church leaders considered a woman's situation when judging abortion, and abortion was listed in Church canons as homicide only when the fetus was formed. St. Thomas Aquinas declared that a fetus first has a vegetative soul, then an animal soul, and finally a rational soul when the body was developed. The next period, 1500-1750, found anyone who resorted to contraception or abortion subject to excommunication (1588), saw these rules relaxed in 1591, and banned abortion even for those who would be murdered because of a pregnancy (1679). From 1750 to the present, excommunication was the punishment for all abortions (1869). This punishment was extended to medical personnel in 1917, but the penalty had exceptions if the woman was young, ignorant, or operating under duress or fear. In 1930, therapeutic abortions were condemned, and, in 1965, abortion was condemned as the taking of life rather than as a sexual sin. By 1974, the right to life argument had taken hold and became part of a theory of

    Within-session habituation and extinction learning co-occur as do subsequent consolidation of habituation (i.e., between-session habituation) and extinction memory. We sought to determine whether, as we predicted: (1) between-session habituation is greater across a night of sleep versus a day awake; (2) time-of-day accounts for differences; (3) between-session habituation predicts consolidation of extinction memory; (4) sleep predicts between-session habituation and/or extinction memory. Participants (N = 28) completed 4-5 sessions alternating between mornings and evenings over 3 successive days (2 nights) with session 1 in either the morning (N = 13) or evening (N = 15). Twelve participants underwent laboratory polysomnography. During 4 sessions, participants completed a loud-tone habituation protocol, while skin conductance response (SCR), blink startle electromyography (EMG), heart-rate acceleration and heart-rate deceleration (HRD) were recorded. For sessions 1 and 2, between-session habituation of EMG, SCR and HRD was greater across sleep. SCR and HRD were generally lower in the morning. Between-session habituation of SCR for sessions 1 and 2 was positively related to intervening (first night) slow wave sleep. In the evening before night 2, participants also underwent fear conditioning and extinction learning phases of a second protocol. Extinction recall was tested the following morning. Extinction recall was predicted only by between-session habituation of SCR across the same night (second night) and by intervening REM. We conclude that: (1) sleep augments between-session habituation, as does morning testing; (2) extinction recall is predicted by concurrent between-session habituation; and (3) both phenomena may be influenced by sleep.

  17. Beyond abortion: the potential reach of a human life amendment.

    Science.gov (United States)

    Westfall, D

    1982-01-01

    In Roe v. Wade, the Supreme Court held that the constitutionally protected right to privacy includes a woman's right to terminate pregnancy. Following the decision, anti-abortion groups turned to Congress to limit or negate that right. As a result of their efforts, several "human life" statutes and constitutional amendments have been proposed. This Article focuses on the implications of proposed amendments that seek to ban or limit the availability of abortions indirectly by broadening the definition of "person" to include unborn individuals. The Article discusses the potentially serious effects such an amendment would have in areas unrelated to abortion. It finds that the resulting chaos and uncertainty would have great social costs, and concludes that if abortions are to be banned or restricted, a human life amendment that directly deals with abortion is preferable to one that defines "person" to include the unborn.

    1993-01-01

    Data from a 1989 CBS News/New York Times survey are used to examine the effect that the framing of questions on abortion has on estimates of what proportions of the population support various legal positions. The nationwide data and results from six state polls show that general questions with only two or three options overestimate the proportions of respondents who either favor a ban on all abortion or who would allow abortion under all circumstances. Questions that pose specific circumstances result in movement of respondents out of extreme categories and into more moderate ones. Even respondents who indicate they would favor abortion in all specific circumstances and those who favor abortion in none are likely to moderate their views when asked if they support restrictions that have been proposed in a number of states.

    2012-01-01

    Full Text Available Problem statement: incidence of abortion in the United States has steadily declined since 1990. The question is why? Approach: This study, using multiple linear regression, examines whether women’s unprotected sexual activity is deterred by the risk of contracting AIDS as reflected in decreased abortion rates. Results: The empirical evidence consistently finds that the prevalence of AIDS reduces the risky (unprotected sexual activity of women of childbearing ages 15-44 as reflected in their abortion rates. The empirical results remain robust for the abortion rates of teens ages 15-17 and for teens ages 15-19. Conclusion: The empirical results suggest that the behavioral modification induced by the prevalence of AIDS accounted for 21% of the decrease in abortion rates over the time period 1992-2005.

  1. Conscientious objection to provision of legal abortion care.

    2013-12-01

    Despite advances in scientific evidence, technologies, and human rights rationale for providing safe abortion, a broad range of cultural, regulatory, and health system barriers that deter access to abortion continues to exist in many countries. When conscientious objection to provision of abortion becomes one of these barriers, it can create risks to women's health and the enjoyment of their human rights. To eliminate this barrier, states should implement regulations for healthcare providers on how to invoke conscientious objection without jeopardizing women's access to safe, legal abortion services, especially with regard to timely referral for care and in emergency cases when referral is not possible. In addition, states should take all necessary measures to ensure that all women and adolescents have the means to prevent unintended pregnancies and to obtain safe abortion.

  2. Abortion law around the world: progress and pushback.

    Science.gov (United States)

    Finer, Louise; Fine, Johanna B

    2013-04-01

    There is a global trend toward the liberalization of abortion laws driven by women's rights, public health, and human rights advocates. This trend reflects the recognition of women's access to legal abortion services as a matter of women's rights and self-determination and an understanding of the dire public health implications of criminalizing abortion. Nonetheless, legal strategies to introduce barriers that impede access to legal abortion services, such as mandatory waiting periods, biased counseling requirements, and the unregulated practice of conscientious objection, are emerging in response to this trend. These barriers stigmatize and demean women and compromise their health. Public health evidence and human rights guarantees provide a compelling rationale for challenging abortion bans and these restrictions.

    2015-12-01

    Contraception following delivery or an induced abortion reduces the risk of an early unintended pregnancy and its associated adverse health consequences. Unmet need for contraception during the postpartum period and contraceptive counseling and services following abortion have been the focus of efforts for the last several decades. This article provides an introduction to the more focused contributions that follow in this special issue. We discuss the validity and measurement of the concept of unmet need for family planning during the postpartum period. We then present key findings on postpartum contraceptive protection, use dynamics, and method mix, followed by an assessment of interventions to improve postpartum family planning. The evidence on postabortion contraceptive uptake and continuation of use remains thin, although encouraging results are noted for implementation of comprehensive abortion care and for the impact of post-abortion contraceptive counseling and services. Drawing on these studies, we outline policy and program implications for improving postpartum and post-abortion contraceptive use.

    The authors evaluated the usefulness of prostaglandin F2 alpha in inducing second trimester abortions in two consecutive groups of patients. Progressive and fractionated intracervical instillation of 10 ml of Tylose gel containing 10 mg of Prostine F2 alpha is the least traumatic method of uterine evacuation in the majority of cases (18 out of 24 cases). Advantages of this method consist of the ease with which it can be performed, that it may be repeated on subsequent days, and that there have been no serious complications. In case of failure, the authors recommend using an intraamnionic injection (usually performed only once) of 40 mg of Prostine F2 alpha diluted in 20 ml of normal saline solution. This more involved method requires an experienced physician and ultrasonography, but is very effective (31 cases out of 3). Exceptionally, this can be repeated after a several day interval if the initial injection fails (2 out of 3). These methods avoid recourse to surgery (except in the case of uterine scarring) in the induction of second trimester abortions.

    The issue of conscientious objection (CO) arises in healthcare when doctors and nurses refuse to have any involvement in the provision of treatment of certain patients due to their religious or moral beliefs. Most commonly CO is invoked when it comes to induced abortion. Of the EU member states where induced abortion is legal, invoking CO is granted by law in 21 countries. The same applies to the non-EU countries Norway and Switzerland. CO is not legally granted in the EU member states Sweden, Finland, Bulgaria and the Czech Republic. The Icelandic legislation provides no right to CO either. European examples prove that the recommendation that CO should not prevent women from accessing services fails in a number of cases. CO puts women in an unequal position depending on their place of residence, socio-economic status and income. CO should not be presented as a question that relates only to health professionals and their rights. CO mainly concerns women as it has very real consequences for their reproductive health and rights. European countries should assess the laws governing CO and its effects on women's rights. CO should not be used as a subtle method for limiting the legal right to healthcare.

    In spite of the mosquito Aedes aegypti being a vector of several infectious diseases, a limited number of studies has been undertaken on learning in this species. Moreover, larval stages have been neglected as model organisms, although they are active, aquatic and perform stereotyped behavioural responses, e.g. the escape response when disturbed. To study the learning abilities of mosquito larvae, we focused on habituation, a form of non-associative learning widely studied in vertebrates and invertebrates. Habituation was defined as the progressive and reversible decrease in response to a reiterative stimulus. We first aimed at confirming habituation of the escape response in mosquito larvae (4th instar). Then, we determined whether a mnesic trace was established. Larvae were individually stimulated with a visual danger stimulus inducing the escape response. We set up a protocol for testing larvae individually, allowing the control of different parameters that are crucial for the study of cognitive abilities. After 15 trials, the escape response of mosquitoes was significantly lower. A disturbance stimulus presented after the 15th trial, induced the escape response and reversed habituation. Retention was confirmed up to 1h after the last habituation trial. This original bioassay can be adapted for studying the physiology of learning and memory in mosquito larvae, for analysing the effects of chemicals in the water, the characterisation of the cognitive abilities related to the life history of different mosquito species across preimaginal stages.

    When the Berlin Wall crumbled on November 9, 1989, few Germans could foresee the coming dramatic changes. But by 1992 Germany faced deep internal divisions as it attempted to merge 2 very different societies. One such division was over abortion. In the West, women had access to abortion services only when they met very specific criteria. In the East, access to abortion within the first trimester had been unhindered since 1972. As agreed to under unification treaty terms, the Federal Republic had until the end of 1992 to design and enact new legislation that would create a legal basis for abortion within united Germany. Under West Germany's criminal code, abortion was allowed only 1) when the physical health of the mother was in danger; 2) when abnormalities in the fetus existed; 3) in cases of rape or incest; or 4) if serious social, psychological, or economic factors made the raising of a child difficult. In the primarily Catholic southern and southwestern portions of West Germany, state governments strictly regulated the use of the social indicator clause. In East Germany abortion costs were covered by social security, and the government guaranteed access to abortion services. The widespread use of contraception kept abortion levels comparatively low to moderate in the East (350 per 1000 births). During the 1970s, as population growth rates in the East shrank to negative levels, a pronatalist policy extended maternity leaves in 1976, and women rearing 2 or more children at home received 90% of their salaries for 1 year. In the West, changes in women's status and levels of income and education have led to a decrease in the size of families. All 5 parties have reform proposals ranging from the further restriction of abortion to the complete removal of existing restrictions. A sizable majority of Germans support a liberalization of the West German criminal codes regarding abortion.

  8. [Historical background of the acceptance of induced abortion].

    1982-12-01

    Japanese attitude toward induced abortion with its historical background is examined. There is a record of induced abortion as early as the beginning of the 12th century. Abortion was practiced frequently as a means of family planning during Edo Period (1603-1867), especially among the poor. Shogunate and feudal lords were aware of the problem but generally acquiesced. Some Buddhist priest preached on the vice of abortion from a humanitarian point of view and suggested that each community should cooperate and regulate the practice. In 1842 Shogunate at last banned induced abortion in the capital, Edo, but left the rest of the country alone. Ironically this practice of voluntary abortion among the poor and the killing of newborns among peasants controlled the size of population of the nation throughout Edo Period, which saw 35 famines and undue taxation on peasants. In 1868 the new government of Meiji announced to have a tight control over midwives who performed abortion in most cases. In modernizing the nation the government advocated enlarged population under the slogan: rich nation with strong soldiers. This trend persisted till the end of World War II. Overpopulation and shortage of food after World War II with soldiers and people from lost colonies returning home prompted Japan to control her population and adopt a eugenic law. It was not until 1970's in the midst of women's liberation movement that Japanese women became aware of their own right to the reproductive aspect of their life. In comparison, in the United States Supreme Court decision in 1973 virtually legalized abortion and each state has responded to it differently. Prior to 1900 induced abortion was accepted as a means of birth control in the United States, and midwives had monopolized that area of medicine. Crusaders of anti-abortion from the turn of the century were not necessarily well publicized Catholics but "licensed" doctors who joined forces in their attempt to shut out midwives from

    Objective To understand the characteristics of induced abortion in China in the 1990s,and to find out the influential factors.Methods The overall number of induced abortions, calculate cohort induced abortion frequency, explore the impact of a child's sex and the number of previous children on induced abortions were estimated by using the data from the "National Population and Reproductive Health Survey" conducted by the National Family Planning Commission in November 1997.Results Induced abortions in China had their own characteristics, which were far different from other countries. The main difference was led by the fact that the country was driven by an implemented family planning program and nationwide population policies. The key cause of induced abortions was due to an inconsistency with the requirements of the family planning policy. However, as a result of effective and prevalent contraception, the rates of induced abortions were not quite high in the 1990s,when compared with other countries. Even though, in the early 1990s, the government had reinforced the family planning program through administration and legislation,unlike during the early 1980s when the one-child policy was implemented, the induced abortion rate and the number of induce abortions did not increase as the fertility rate substantially decreased.Concltsion This finding implies that the fertility declines in the 1990s were not caused by the number of induced abortions. The transition of the fertility ideology of the people has played an important role in the fertility decline, as institutional reform and socioeconomic development are implemented.

    The purpose of this study was to examine associations between abortion history and a wide range of anxiety (panic disorder, panic attacks, PTSD, Agoraphobia), mood (bipolar disorder, mania, major depression), and substance abuse disorders (alcohol and drug abuse and dependence) using a nationally representative US sample, the national comorbidity survey. Abortion was found to be related to an increased risk for a variety of mental health problems (panic attacks, panic disorder, agoraphobia, PTSD, bipolar disorder, major depression with and without hierarchy), and substance abuse disorders after statistical controls were instituted for a wide range of personal, situational, and demographic variables. Calculation of population attributable risks indicated that abortion was implicated in between 4.3% and 16.6% of the incidence of these disorders. Future research is needed to identify mediating mechanisms linking abortion to various disorders and to understand individual difference factors associated with vulnerability to developing a particular mental health problem after abortion.

    influence on her offspring’s behaviour. This study investigated whether fearfulness in foals can be reduced through weekly exposure to usually frightening objects with a habituated mother during the first 8 weeks of life. Prior to foaling, mares (N = 22) were habituated to five initially fear......-partum. Control mares were inside the empty test arena with their foals for the same amount of time. The foals were tested at 8 weeks and 5 months of age in four standardised fear tests. Demonstration foals showed significantly reduced fear responses (behaviour and heart rate) and increased exploratory behaviour...... at both 8 weeks and 5 months of age. The effect was likely achieved through a combination of maternal transmission and individual learning. It is concluded that fearfulness in foals may be reduced through exposure to frightening objects together with their habituated mother during the first 8 weeks...

    In this paper, a novel non-stationary model of functional Magnetic Resonance Imaging (fMRI) time series is proposed. It allows us to account for some putative habituation effect arising in event-related fMRI paradigms that involves the so-called repetition-suppression phenomenon and induces decreasing magnitude responses over successive trials. Akin, this model is defined over functionally homogeneous regions-of-interest (ROIs) and embedded in a joint detection-estimation approach of brain activity. Importantly, its non-stationarity character is embodied in the trial-varying nature of the BOLD response magnitude. Habituation and activation maps are then estimated within the Bayesian framework in a fully unsupervised MCMC procedure. On artificial fMRI datasets, we show that habituation effects can be accurately recovered in activating voxels. (authors)

    Habituation is a highly conserved phenomenon that remains poorly understood at the molecular level. Invertebrate model systems, like Caenorhabditis elegans, can be a powerful tool for investigating this fundamental process. Here we established a high-throughput learning assay that used real-time computer vision software for behavioral tracking and optogenetics for stimulation of the C. elegans polymodal nociceptor, ASH. Photoactivation of ASH with ChR2 elicited backward locomotion and repetitive stimulation altered aspects of the response in a manner consistent with habituation. Recording photocurrents in ASH, we observed no evidence for light adaptation of ChR2. Furthermore, we ruled out fatigue by demonstrating that sensory input from the touch cells could dishabituate the ASH avoidance circuit. Food and dopamine signaling slowed habituation downstream from ASH excitation via D1-like dopamine receptor, DOP-4. This assay allows for large-scale genetic and drug screens investigating mechanisms of nociception modulation.

    Kernels cultured in vitro were induced to abort by high temperature (35 degrees C) and by culturing six kernels/cob piece. Aborting kernels failed to enter a linear phase of dry mass accumulation and had a final mass that was less than 6% of nonaborting field-grown kernels. Kernels induced to abort by high temperature failed to synthesize starch in the endosperm and had elevated sucrose concentrations and low fructose and glucose concentrations in the pedicel during early growth compared to nonaborting kernels. Kernels induced to abort by high temperature also had much lower pedicel soluble acid invertase activities than did nonaborting kernels. These results suggest that high temperature during the lag phase of kernel growth may impair the process of sucrose unloading in the pedicel by indirectly inhibiting soluble acid invertase activity and prevent starch synthesis in the endosperm. Kernels induced to abort by culturing six kernels/cob piece had reduced pedicel fructose, glucose, and sucrose concentrations compared to kernels from field-grown ears. These aborting kernels also had a lower pedicel soluble acid invertase activity compared to nonaborting kernels from the same cob piece and from field-grown ears. The low invertase activity in pedicel tissue of the aborting kernels was probably caused by a lack of substrate (sucrose) for the invertase to cleave due to the intense competition for available assimilates. In contrast to kernels cultured at 35 degrees C, aborting kernels from cob pieces containing all six kernels accumulated starch in a linear fashion. These results indicate that kernels cultured six/cob piece abort because of an inadequate supply of sugar and are similar to apical kernels from field-grown ears that often abort prior to the onset of linear growth.

  16. Neural Correlates of Empathy with Pain Show Habituation Effects. An fMRI Study.

    Mira A Preis

    Full Text Available Neuroimaging studies have demonstrated that the actual experience of pain and the perception of another person in pain share common neural substrates, including the bilateral anterior insular cortex and the anterior midcingulate cortex. As many fMRI studies include the exposure of participants to repeated, similar stimuli, we examined whether empathic neural responses were affected by habituation and whether the participants' prior pain experience influenced these habituation effects.In 128 trials (four runs, 62 participants (31 women, 23.0 ± 4.2 years were shown pictures of hands exposed to painful pressure (pain pictures and unexposed (neutral pictures. After each trial, the participants rated the pain of the model. Prior to the experiment, participants were either exposed to the same pain stimulus (pain exposure group or not (touch exposure group. In order to assess possible habituation effects, linear changes in the strength of the BOLD response to the pain pictures (relative to the neutral pictures and in the ratings of the model's pain were evaluated across the four runs.Although the ratings of the model's pain remained constant over time, we found neural habituation in the bilateral anterior/midinsular cortex, the posterior midcingulate extending to dorsal posterior cingulate cortex, the supplementary motor area, the cerebellum, the right inferior parietal lobule, and the left superior frontal gyrus, stretching to the pregenual anterior cingulate cortex. The participant's prior pain experience did neither affect their ratings of the model's pain nor their maintenance of BOLD activity in areas associated with empathy. Interestingly, participants with high trait personal distress and fantasy tended to show less habituation in the anterior insula.Neural structures showed a decrease of the BOLD signal, indicating habituation over the course of 45 minutes. This can be interpreted as a neuronal mechanism responding to the repeated exposure to

    The Yellowstone grizzly bear (Ursus arctos horribilis) population may be extirpated during the next 100-200 years unless mortality rates stabilize and remain at acceptable low levels. Consequently, we analyzed relationships between Yellowstone grizzly bear mortality and frequency of human habituation among bears and size of the whitebark pine (Pinus albicaulis) seed crop. During years of large seed crops, bears used areas within 5 km of roads and 8 km of developments half as intensively as during years of small seed crops because whitebark pine's high elevation distribution is typically remote from human facilities. On average, management trappings of bears were 6.2 times higher, mortality of adult females 2.3 times higher, and mortality of subadult males 3.3 times higher during years of small seed crops. We hypothesize that high mortality of adult females and subadult males during small seed crop years was a consequence of their tendency to range closest (of all sex-age cohorts) to human facilities; they also had a higher frequency of human habituation compared with adult males. We also hypothesize that low morality among subadult females during small seed crop years was a result of fewer energetic stressors compared with adult females and greater familiarity with their range compared with subadult males; mortality was low even though they ranged close to humans and exhibited a high frequency of human habituation. Human-habituated and food-conditioned bears were 2.9 times as likely to range within 4 km of developments and 3.1 times as often killed by humans compared with nonhabituated bears. We argue that destruction of habituated bears that use native foods near humans results in a decline in the overall ability of bears to use available habitat; and that the number and extent of human facilities in occupied grizzly bear habitat needs to be minimized unless habituated bears are preserved and successful ways to manage the associated risks to humans are developed.

    This study examined the links between desensitization to violent media stimuli and habitual media violence exposure as a predictor and aggressive cognitions and behavior as outcome variables. Two weeks after completing measures of habitual media violence exposure, trait aggression, trait arousability, and normative beliefs about aggression, undergraduates (N = 303) saw a violent film clip and a sad or a funny comparison clip. Skin conductance level (SCL) was measured continuously, and ratings of anxious and pleasant arousal were obtained after each clip. Following the clips, participants completed a lexical decision task to measure accessibility of aggressive cognitions and a competitive reaction time task to measure aggressive behavior. Habitual media violence exposure correlated negatively with SCL during violent clips and positively with pleasant arousal, response times for aggressive words, and trait aggression, but it was unrelated to anxious arousal and aggressive responding during the reaction time task. In path analyses controlling for trait aggression, normative beliefs, and trait arousability, habitual media violence exposure predicted faster accessibility of aggressive cognitions, partly mediated by higher pleasant arousal. Unprovoked aggression during the reaction time task was predicted by lower anxious arousal. Neither habitual media violence usage nor anxious or pleasant arousal predicted provoked aggression during the laboratory task, and SCL was unrelated to aggressive cognitions and behavior. No relations were found between habitual media violence viewing and arousal in response to the sad and funny film clips, and arousal in response to the sad and funny clips did not predict aggressive cognitions or aggressive behavior on the laboratory task. This suggests that the observed desensitization effects are specific to violent content.

    A ubiquitous feature of an animal's response to an odorant is that it declines when the odorant is frequently or continuously encountered. This decline in olfactory response, termed olfactory habituation, can have temporally or mechanistically different forms. The neural circuitry of the fruit fly Drosophila melanogaster's olfactory system is well defined in terms of component cells, which are readily accessible to functional studies and genetic manipulation. This makes it a particularly useful preparation for the investigation of olfactory habituation. In addition, the insect olfactory system shares many architectural and functional similarities with mammalian olfactory systems, suggesting that olfactory mechanisms in insects may be broadly relevant. In this chapter, we discuss the likely mechanisms of olfactory habituation in context of the participating cell types, their connectivity, and their roles in sensory processing. We overview the structure and function of key cell types, the mechanisms that stimulate them, and how they transduce and process odor signals. We then consider how each stage of olfactory processing could potentially contribute to behavioral habituation. After this, we overview a variety of recent mechanistic studies that point to an important role for potentiation of inhibitory synapses in the primary olfactory processing center, the antennal lobe, in driving the reduced response to familiar odorants. Following the discussion of mechanisms for short- and long-term olfactory habituation, we end by considering how these mechanisms may be regulated by neuromodulators, which likely play key roles in the induction, gating, or suppression of habituated behavior, and speculate on the relevance of these processes for other forms of learning and memory.

    The prevalence of oral malodor and association of habitual mouth breathing with oral malodor were investigated in children residing in rural areas. One hundred and nineteen children participated in this study. A sulfide monitor and organoleptic method were used to evaluate oral malodor. About 8% of children had a sulfide level in mouth air above the socially acceptable limit (75 ppb). Habitual mouth breathing was a factor contributing to oral malodor. Oral malodor was not significantly correlated with plaque index, history of caries or frequency of toothbrushing.

    Full Text Available OBJECTIVE: To assess the Outcome of pregnancy in patients with threatened abortion. METHODS: A Prospective observational study was done on 106 pregnant women with threatened abortion. Out comes in the form of antenatal complications, mode of delivery and postnatal co mplications were noted. Analysis of the data was done using SPSS version 13. RESULTS: In the study of 106 patients 18% had spontaneous abortion. Pre - labour rupture of membranes were seen in 20% of patients and 21% had preterm labour. Threatened abortion di d not affect mode of delivery. PPROM, preterm births were more in women presenting with first trimester bleeding; PIH, PROM, and postpartum complications were more in women presenting beyond 20 weeks gestation though statistically not significant. 13.2% of women had heavy bleeding at admission out of which 50% aborted subsequently – significantly higher than the light bleeding group. CONCLUSION: The overall maternal and perinatal outcome in women with threatened abortion is suboptimal. Women with heavy blee ding are more likely to abort than women with light bleeding. Among the prognostic factors, only the amount of bleeding had significant prognostic accuracy

    In Hohoe, Ghana, induced abortion is the second highest cause of hospital admissions. We aimed to describe factors influencing induced abortion among 408 randomly selected women aged 15-49 years. 21% of the women had had an abortion; of those, 36% said they did not want to disrupt their education or employment; 66% of the abortions were performed by doctors. Bivariate logistic regression showed that compared with women with secondary education, women with basic education (OR = 0.31, 95% CI: 0.18-0.54) and uneducated women (OR = 0.24, 95% CI: 0.07-0.70) were significantly less likely to have had an abortion. Women who were married (OR = 1.83, 95% CI: 1.10-3.04), peri-urban residents (OR = 1.88, 95% CI: 0.95-3.94), and women with formal employment (OR = 2.22, 95% CI: 0.86-5.45) were more likely to have had an abortion. Stakeholders should improve access to effective contraception to lower the chance of needing an abortion and target education programmes at those with unmet need for contraception.

  6. Abort Trigger False Positive and False Negative Analysis Methodology for Threshold-Based Abort Detection

    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.

    Researchers have established that individuals' abortion knowledge is positively associated with their support of abortion rights. However, social workers' personal beliefs regarding abortion are under-researched, even though social workers are often employed in health promotion and education roles in which the topic of abortion is encountered. The current study examines the results of a nationwide survey of social work students (N = 504) and explores the relationship between social work students' abortion knowledge and abortion attitudes. Less abortion knowledge was significantly associated with antichoice attitude endorsement. Implications for social work research, training, and education are subsequently discussed.

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

    In Brazil, induced abortion is considered a crime in the majority of cases, the result being that there is little official data on the subject. Little is known about the conditions under which abortions are induced This research was designed to shed light on the characteristics of the women who had had an abortion and to study the reasons why and conditions under which it occurred. The sample consisted of all employees (7,359) and students (2,231) in a university program in S o Paulo who were mailed a self-administered survey. Accompanying the questionnaire was a letter and self-addressed stamped envelope. 27% of the employees and 42% of the students returned the questionnaires. Of these, 1,314 employees and 138 students had had at least one pregnancy. The results presented in this study show that 465 of the employees and students ar some point had thought of having an abortion. They were divided into two groups: those who had had an abortion and those who had nos. The objective was to analyze the association of some characteristics of the women with their decision to have/not have an abortion and how they felt when faced with this decision. The proportion of women who had had an abortion was significantly lower among married women than singles. A larger percentage of women who had talked with a friend and/or husband/partner/boyfriend had decided to have an abortion than those who had talked to a parent or had not talked to anyone. More women who said they were not prepared to raise/educate a child had had an abortion as compared to those giving other reasons. Almost half of the women undergoing an abortion said that they felt bad emotionally and physically afterwards. Among those who had not had an abortion, almost two-fifths reported that they felt good, were happy, relieved, and did not regret their decision. The conclusion drawn from the population studied was that emotional and social factors played a significant role in the decision-making process for women

  11. Abortion denied--outcome of mothers and babies.

    A consistent argument favoring therapeutic abortions has been that mothers who are denied abortions will seek "illegal" help elsewhere, often in less than optimal conditions. Yet, a review of published reports on women who had been denied abortion and were followed up shows that 70.67% of the 6298 women completed their pregnancies and only 13.2% had an abortion elsewhere. Several studies have shown that the incidence of Complications of pregnancy is no greater in mothers denied abortion than in paired controls. The results of a prospective study by Laukaran and Van Den Berg showed a higher incidence of maternal accidental injury, a borderline increase of maternal accidental injury, a borderline increase in the prevalence of congenital anomalies, and a higher incidence of infection and hemorrhage during the puerperium in women who had been denied abortion. They concluded that maternal attitude and psychosocial stress had little effect on the progress of the pregnancy and labor. Published reports on the psychological effects on the children of women who had been denied abortion are few, mainly because longterm follow-up is required. In 1966 Forssman and Thuwe described the results of their study of 120 children whose mothers had been denied abortion. The children had been followed up until their 21st birthdays. The controls had been carefully paired. The proportion of children who had been placed in foster and children's homes was significantly higher among the "unwanted" children than among the controls (50% versus 18%). There was no statistically significant difference in the rates of drunken misconduct, crime, or "educational mental subnormality" between the 2 groups, but the incidence rates of delinquency and psychiatric consultation were 10% and 13% higher respectively among the unwanted children than among the controls. There have been virtually no objective studies on the psychologic and social well-being of women who have been denied abortion. The literature

    Nowadays, the issue of abortion poses an ethical problem and the society is divided into two camps whose opinions vary considerably. On the one hand there are those who support the right to abortion, and on the other hand there are antiabortionists who believe that already at the moment of conception, a human individual who has the right to life is starting to form, and they consider abortion murder.

    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 and improved stability of the RHIC operation.

    The state of Texas began enforcement of the Woman's Right to Know (WRTK) Act on January 1, 2004. The law requires that all abortions at 16 weeks gestation or later be performed in an ambulatory surgical center (ASC). In the month the law went into effect, not one of Texas's 54 non-hospital abortion providers met the requirements of a surgical center. The effect was immediate and dramatic. The number of abortions performed in Texas at 16 weeks gestation or later dropped 88 %, from 3642 in 2003...

    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.

    Because sex-selective abortions are generally conducted during the second term of the pregnancy, timing of abortion can be used as an indirect way of studying sex-selection by abortion. We examined the likelihood of having a first-trimester vs. second-trimester abortion among a group of 885 married women who had an abortion in an obstetric hospital in Hanoi in 2003. In the absence of sex-selection by abortion, the number and sex of living children should not affect the timing of abortion. Results indicate that women with more children, particularly those with more daughters or without a son, were more likely to undergo a second-term abortion than a first-term abortion. We estimate that, in 2003, 2 per cent of all abortions to women with at least one living child were intended to avoid the birth of a female.

    2009-01-01

    This paper provides a review of abortion studies produced in the field of public health in Brazil, highlighting current research gaps and challenges. Most studies focus on women admitted to public hospitals for treatment of incomplete abortion, so their scope is limited to abortions presenting complications. Women's profiles, abortion methods, motives, and immediate consequences for women's physical health are also included. However, there remains a need for studies on the following aspects: measuring abortion incidence; investigating cases of post-abortion complications and death; analyzing the relationship between abortion and contraception; investigating the impact of abortion on women's mental health; and incorporating men's perspectives. There is an urgent need for evaluative research on abortion care in public services. Research results should be disseminated widely, so as to help overcome any ideological bias in the current debate on abortion rights in the country.

    Unsafe abortions remain a major public health problem in countries with very restrictive abortion laws. In Brazil, parliamentarians - who have the power to change the law - are influenced by "public opinion", often obtained through surveys and opinion polls. This paper presents the findings from two studies. One was carried out in February-December 2010 among 1,660 public servants and the other in February-July 2011 with 874 medical students from three medical schools, both in São Paulo State, Brazil. Both groups of respondents were asked two sets of questions to obtain their opinion about abortion: 1) under which circumstances abortion should be permitted by law, and 2) whether or not women in general and women they knew who had had an abortion should be punished with prison, as Brazilian law mandates. The differences in their answers were enormous: the majority of respondents were against putting women who have had abortions in prison. Almost 60% of civil servants and 25% of medical students knew at least one woman who had had an illegal abortion; 85% of medical students and 83% of civil servants thought this person(s) should not be jailed. Brazilian parliamentarians who are currently reviewing a reform in the Penal Code need to have this information urgently.

  20. Influence of Estrogen Receptor α Polymorphisms on Bone Density in Response to Habitual Exercise in Japanese Postmenopausal Women

    Full Text Available Estrogen receptor α (ERα is one of candidate genes for osteoporosis. This study examined the influence of ERα gene, PvuII, and XbaI genotypes on bone density of calcaneus in response to habitual exercise. ERα polymorphisms were detected using PvuII and XbaI restriction enzymes in 316 Japanese postmenopausal women. The bone density was significantly lower in the women carrying PP, pp, or xx genotype without habitual exercise than in the age-matched women without those genotypes. The women carrying Pp genotype without habitual exercise had normal bone density compared to those without Pp genotype. The women carrying PPxx or ppxx polymorphism without habitual exercise had low bone density compared to those with habitual exercise. Thus, the reduction of bone density was attenuated in the women carrying PPxx or ppxx with habitual exercise. In addition, habitual exercise was highly effective for the bone density in the women carrying xx homozygote. These findings indicate that analyses of XbaI and PvuII polymorphisms of ERα may be useful to predict the effect of exercise on bone density, and habitual exercise attenuates the reduction of bone density in women with some genotypes.

    Increasing evidence supports that physical activity promotes mental health; and regular exercise may confer positive effects in neurological disorders. There is growing number of reports that requires the analysis of the impact of physical activity in animal models. Exercise in rodents can be performed under voluntary or forced conditions. The former presents the disadvantage that the volume and intensity of exercise varies from subject to subject. On the other hand, a major challenge of the forced training protocol is the low level of performance typically achieved within a given session. Thus, the aim of the present study was to evaluate the effectiveness of gradual increasing of the volume and intensity (training habituation protocol) to improve the locomotor performance in a forced running-wheel system in rats. Sprague-Dawley rats were randomly assigned to either a group that received an exercise training habituation protocol, or a control group. The locomotor performance during forced running was assessed by an incremental exercise test. The experimental results reveal that the total running time and the distance covered by habituated rats was significantly higher than in control ones. We conclude that the exercise habituation protocol improves the locomotor performance in forced running wheels. PMID:28337132

    The purpose of this study was to examine the effect of barefoot running on initial loading rate (LR), lower extremity joint kinematics and kinetics, and neuromuscular control in habitually shod runners with an emphasis on the individual response to this unfamiliar condition. Kinematics and ground reaction force data were collected from 51 habitually shod runners during overground running in a barefoot and shod condition. Joint kinetics and stiffness were calculated with inverse dynamics. Inter-individual initial LR variability was explored by separating individuals by a barefoot/shod ratio to determine acute responders/non-responders. Mean initial LR was 54.1% greater in the barefoot when compared to the shod condition. Differences between acute responders/non-responders were found at peak and initial contact sagittal ankle angle and at initial ground contact. Correlations were found between barefoot sagittal ankle angle at initial ground contact and barefoot initial LR. A large variability in biomechanical responses to an acute exposure to barefoot running was found. A large intra-individual variability was found in initial LR but not ankle plantar-dorsiflexion between footwear conditions. A majority of habitually shod runners do not exhibit previously reported benefits in terms of reduced initial LRs when barefoot. Lastly, runners who increased LR when barefoot reduced LRs when wearing shoes to levels similar seen in habitually barefoot runners who do adopt a forefoot-landing pattern, despite increased dorsiflexion.

    In some situations, animals seem to ignore stimuli which in other contexts elicit a robust response. This attenuation in behavior, which enables animals to ignore a familiar, unreinforced stimulus, is called habituation. Despite the ubiquity of this phenomenon, it is generally poorly understood in terms of the underlying neural circuitry. Hungry…

    Runners are often categorized as forefoot, midfoot or rearfoot strikers, but how much and why do individuals vary in foot strike patterns when running on level terrain? This study used general linear mixed-effects models to explore both intra- and inter-individual variations in foot strike pattern among 48 Kalenjin-speaking participants from Kenya who varied in age, sex, body mass, height, running history, and habitual use of footwear. High speed video was used to measure lower extremity kinematics at ground contact in the sagittal plane while participants ran down 13 meter-long tracks with three variables independently controlled: speed, track stiffness, and step frequency. 72% of the habitually barefoot and 32% of the habitually shod participants used multiple strike types, with significantly higher levels of foot strike variation among individuals who ran less frequently and who used lower step frequencies. There was no effect of sex, age, height or weight on foot strike angle, but individuals were more likely to midfoot or forefoot strike when they ran on a stiff surface, had a high preferred stride frequency, were habitually barefoot, and had more experience running. It is hypothesized that strike type variation during running, including a more frequent use of forefoot and midfoot strikes, used to be greater before the introduction of cushioned shoes and paved surfaces.

    Schizophrenic patients exhibit deficits in indices of sensorimotor gating, such as habituation and prepulse inhibition (PPI) of the startle reflex. Hallucinogenic drug-induced states are putative models for the early and acute stages of schizophrenic and schizophrenia-spectrum disorders. Hallucinogenic drugs have been shown to disrupt PPI and/or retard habituation of the startle reflex in animal models of schizophrenia, consistent with the view of hallucinogen-induced states as 'model psychoses'. We evaluated the effects of the hallucinogen psilocybin on PPI and habituation of the startle reflex in a double-blind, placebo-controlled human study with 12 healthy subjects. In contrast to animal studies, in our small human sample, psilocybin increased PPI, while having no clear effect on habituation (n = 6). These findings must be considered preliminary because several factors, including dose regimens and experimental parameters, may influence the results of studies on startle plasticity. Further investigations both with psychotic patients in different stages of the disease and with human and animal models of schizophrenia are needed in order to explore the effects of hallucinogens on sensorimotor gating and the relationship between information processing in hallucinogenic drug-induced states and the naturally occurring psychoses.

    Full Text Available An outbreak of abortion by Toxoplasma gondii in goats on a farm in the Brazilian Midwest is reported. Gross lesions were not observed in seven aborted fetuses submitted to the Veterinary Pathology Laboratory, Federal University of Mato Grosso, for necropsy investigation. The main histologic lesions were mononuclear cell pneumonia and necrotizing encephalitis in varying degrees of intensity. PCR for Brucella abortus and Neospora caninum and aerobic cultures were negative in all cases. Antibody titles against T. gondii varying from 1:1024 to 1:32.768 were detected in serum samples from four aborted goats. Nested-PCR assay for T. gondii were positive in brain samples of all cases submitted. These findings indicate that T. gondii infection should be considered in the diagnosis of abortion in goats in Midwest Brazil.

    The clinical value has been assessed of circulating placental lactogen levels as a pointer to the outcome in a patient with vaginal bleeding in early pregnancy. By using a semiautomated radioimmunoassay the normal range of values for the first and second trimesters has been established. In patients admitted with vaginal bleeding after the eighth week of gestation estimation of plasma human placental lactogen showed that patients with low levels were those in whom the abortion was completed during the first admission. Women whose pregnancies continued normally or who aborted after their first discharge from hospital had normal levels. In a small group sampled before the onset of bleeding but who later aborted the mean levels were lower than normal. This simple and inexpensive test can indicate those women in whom abortion is inevitable and could be used to reduce substantially the length of hospital stay in this common complication of early pregnancy.

    Boyle, Elizabeth H; Kim, Minzee; Longhofer, Wesley

    2015-11-01

    Controversy sets abortion apart from other issues studied by world society theorists, who consider the tendency for policies institutionalized at the global level to diffuse across very different countries. The authors conduct an event history analysis of the spread (however limited) of abortion liberalization policies from 1960 to 2009. After identifying three dominant frames (a women's rights frame, a medical frame, and a religious, natural family frame), the authors find that indicators of a scientific, medical frame show consistent association with liberalization of policies specifying acceptable grounds for abortion. Women's leadership roles have a stronger and more consistent liberalizing effect than do countries' links to a global women's rights discourse. Somewhat different patterns emerge around the likelihood of adopting an additional policy, controlling for first policy adoption. Even as support for women's autonomy has grown globally, with respect to abortion liberalization, persistent, powerful frames compete at the global level, preventing robust policy diffusion.

    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.

    Full Text Available 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.

    The hypothesis that the legalisation of abortion contributed significantly to the reduction of crime in the United States in 1990s is one of the most prominent ideas from the recent 'economics-made-fun' movement sparked by the book Freakonomics. This paper expands on the existing literature about the computational stability of abortion-crime regressions by testing the sensitivity of coefficients' estimates to small amounts of data perturbation.

    Ethics is the science of human behavior in society. Ethical discussions are daily inserted within a new social dimension, such as abortion and embryo reduction. Abortion is the interruption of pregnancy spontaneously or intentionally, resulting in the death of the still-to-be-born child. The Brazilian Federal Constitution and Civil Law guarantee the right to life from conception and provides the right of personality to the born child. However, the juridical ordering does not pinpoint the time...

  7. Piriformis pyomyositis with sciatica: an unrecognized complication of "unsafe" abortions.

    Colmegna, Ines; Justiniano, Maria; Espinoza, Luis R; Gimenez, Carlos R

    2007-04-01

    We report the case of a patient who presented with right sciatic pain as a manifestation of piriformis muscle syndrome 1 month after a clandestine- induced abortion. MRI revealed the presence of a piriformis abscess. Staphylococcus aureus was isolated from blood cultures and from the purulent material obtained by CT-guided aspiration. Piriformis pyomyositis should be recognized as a potential complication of "unsafe" abortions that if left untreated could progress to sepsis and death.

  8. "After birth" abortion: a biomedical and conceptual nonsense.

    Recently, two authors suggested that killing a healthy newborn might be morally permissible, subsuming it under the heading of 'after birth abortion'. Their proposed new definition implies that infanticide should be permitted whenever II trimester abortion for social reasons is. The suggestion stirred public outcry; nonetheless it needs to be analyzed since some 20% of countries allow II trimester abortion for social reasons and 5% do this on demand. A proper delimitation of the definition of "abortion" is thus very important to ensure careful application; for this reason we have attempted a critical analysis of their arguments. In the area of pregnancy termination different moral standards are apparently applied in different countries, but many reasons exist why the equation between II trimester abortion for social reasons and the killing of healthy neonates is to be morally rejected in all cases. The "inversed reification" of the concept of infanticide as a more abstract, euphemistic 'after birth abortion' blurs the fundamental difference between a non-viable fetus and a viable neonate. The best-known and most widely utilized (although illegal) "social reason" for "late abortion" and "infanticide" is a pregnancy with a female fetus or neonate. If infanticide for neonates were to be considered morally permissible, specifically it is this practice that would be applied. And this should be rejected on two levels: conceptual, through a critique of the exclusive use of one specific notion of personhood, and pragmatic through refusal of gender-discriminatory forms of infanticide (the killing of female neonates). In conclusion, having investigated the new concept we have concluded that the term "after birth abortion" is biologically and conceptually nonsensical.

    Full Text Available Abstract Background Previous studies have demonstrated a profound lack of habituation in 129P3 mice compared to the habituating, but initially more anxious, BALB/c mice. The present study investigated whether this non-adaptive phenotype of 129P3 mice is primarily based on anxiety-related characteristics. Methods To test this hypothesis and extend our knowledge on the behavioural profile of 129P3 mice, the effects of the anxiolyticdiazepam (1, 3 and 5 mg/kg and the putative anxiolytic metabotropic glutamate receptor 5 (mGlu5R antagonist 2-methyl-6-(phenylethynylpyridine (MPEP, 3, 10 and 30 mg/kg treatment on within-trial (intrasession habituation, object recognition (diazepam: 1 mg/kg; MPEP 10 mg/kg and on the central-nervous expression of the immediate early gene c-Fos (diazepam: 1 mg/kg; MPEP 10 mg/kg were investigated. Results Behavioural findings validated the initially high, but habituating phenotype of BALB/c mice, while 129P3 mice were characterized by impaired intrasession habituation. Diazepam had an anxiolytic effect in BALB/c mice, while in higher doses caused behavioural inactivity in 129P3 mice. MPEP revealed almost no anxiolytic effects on behaviour in both strains, but reduced stress-induced corticosterone responses only in 129P3 mice. These results were complemented by reduced expression of c-Fos after MPEP treatment in brain areas related to emotional processes, and increased c-Fos expression in higher integrating brain areas such as the prelimbic cortex compared to vehicle-treated 129P3 mice. Conclusions These results suggest that the strain differences observed in (nonadaptive anxiety behaviour are at least in part mediated by differences in gamma-aminobutyric acid- A and mGluR5 mediated transmission.

  12. Modification of Male Courtship Motivation by Olfactory Habituation via the GABAA Receptor in Drosophila melanogaster.

    Directory of Open Access Journals (Sweden)

    Shin-Ichiro Tachibana

    Full Text Available A male-specific component, 11-cis-vaccenyl acetate (cVA works as an anti-aphrodisiac pheromone in Drosophila melanogaster. The presence of cVA on a male suppresses the courtship motivation of other males and contributes to suppression of male-male homosexual courtship, while the absence of cVA on a female stimulates the sexual motivation of nearby males and enhances the male-female interaction. However, little is known how a male distinguishes the presence or absence of cVA on a target fly from either self-produced cVA or secondhand cVA from other males in the vicinity. In this study, we demonstrate that male flies have keen sensitivity to cVA; therefore, the presence of another male in the area reduces courtship toward a female. This reduced level of sexual motivation, however, could be overcome by pretest odor exposure via olfactory habituation to cVA. Real-time imaging of cVA-responsive sensory neurons using the neural activity sensor revealed that prolonged exposure to cVA decreased the levels of cVA responses in the primary olfactory center. Pharmacological and genetic screening revealed that signal transduction via GABAA receptors contributed to this olfactory habituation. We also found that the habituation experience increased the copulation success of wild-type males in a group. In contrast, transgenic males, in which GABA input in a small subset of local neurons was blocked by RNAi, failed to acquire the sexual advantage conferred by habituation. Thus, we illustrate a novel phenomenon in which olfactory habituation positively affects sexual capability in a competitive environment.

  13. Testing the influence of habituation on genetic structure of brown bear (Ursus arctos

    Full Text Available Adult bear individuals live solitary and haveprolonged parent–offspring relationships, therefore the share of learned skills compared to the inherited ones is much larger than in other carnivores. This promotes acquisition of deviated behavior and simultaneously establishment of a kinship structure. However, deviated bear behavior and human food conditioning are the symptoms of habituation. The aim of this paper is to test the genetic structuring of habituated and non-habituated individuals located in the central region of Romania (Braşov and Prahova districts, a hotspot in terms of human-bear conflicts. Seven microsatellites were used to genotype 145 samples (ear clips and tissue, out of which 82 were classified as habituated and 63 as wild individuals, respectively. Our results suggest the presence of kinship structures in habituated bear group and a reduction of genetic diversity (He = 0.75, while the group located in the wild registered a higher genetic diversity (He = 0.78 and more private alleles. The genetic differentiation suggested by the Neighbor joining cluster analysis has been strengthened by the two percent (AMOVA differences between the two groups and highlights the negative impact of brown bear kinship structure, caused by the human expansion on wilderness. The genetic analyses indicated that the two groups share genetic variants due to the dispersal and breeding patterns of male adult bears. The emergence of genetic differences between the two groups can be avoided by preventing bears to become human-food conditioned; over time, kinship structure can pose a threat to genetic diversity.

    Endurance running may have a long evolutionary history in the hominin clade but it was not until very recently that humans ran wearing shoes. Research on modern habitually unshod runners has suggested that they utilize a different biomechanical strategy than runners who wear shoes, namely that barefoot runners typically use a forefoot strike in order to avoid generating the high impact forces that would be experienced if they were to strike the ground with their heels first. This finding suggests that our habitually unshod ancestors may have run in a similar way. However, this research was conducted on a single population and we know little about variation in running form among habitually barefoot people, including the effects of running speed, which has been shown to affect strike patterns in shod runners. Here, we present the results of our investigation into the selection of running foot strike patterns among another modern habitually unshod group, the Daasanach of northern Kenya. Data were collected from 38 consenting adults as they ran along a trackway with a plantar pressure pad placed midway along its length. Subjects ran at self-selected endurance running and sprinting speeds. Our data support the hypothesis that a forefoot strike reduces the magnitude of impact loading, but the majority of subjects instead used a rearfoot strike at endurance running speeds. Their percentages of midfoot and forefoot strikes increased significantly with speed. These results indicate that not all habitually barefoot people prefer running with a forefoot strike, and suggest that other factors such as running speed, training level, substrate mechanical properties, running distance, and running frequency, influence the selection of foot strike patterns.

    There is evidence supporting that habitual barefoot runners are able to disperse impact loading rates by landing pattern modification. Yet, case studies suggested that barefoot running may result in severe running injuries, such as metatarsal and calcaneal stress fractures. Injuries may be due to a difference in biomechanical response between habitual and novice barefoot runners. This study investigated the initial effects of barefoot running in habitual shod runners in terms of landing pattern modification and vertical loading rates. Thirty habitual shod runners (mean age 25.5±5.2years; 18 men; with a minimum running mileage of 30km per week for at least one year) ran on an instrumented treadmill at 10km/h shod and barefoot in a randomized order. Vertical average (VALR) and instantaneous loading rates (VILR) were obtained by established methods. Landing pattern was presented as a ratio between the number of footfalls with a heelstrike and the total step number. Twenty participants demonstrated an automatic transition to a non-heelstrike landing during barefoot running, whereas a mixed landing pattern was observed in 10 participants. Compared to shod running, both VALR and VILR were significantly reduced during barefoot running (pbarefoot running, regardless of the landing pattern. VALR for the non-heelstrike pattern during barefoot running was significantly lower than participants with a mixed landing pattern. Conversely, we observed two participants who completely altered their landing patterns, presented high VALR and VILR values. Habitual shod runners presented lower loading rates during barefoot running but their landing pattern transitions were not uniform. Novice barefoot runners with a mixed landing pattern may sustain higher loading rates, compared with those who completely avoided heelstrike pattern. However, a complete landing pattern modification may not guarantee lower loading rates.

    When exposed to a cold environment, a barehanded person experiences pain, cold sensation, and reduced manual dexterity. Both acute (e.g. exercise) and chronic (e.g. cold acclimatization or habituation) processes might lessen these negative effects. The purpose of this experiment was to determine the effect of cold habituation on physiology, perception, and manual dexterity during rest, exercise, and recovery in 5 °C. Six cold weather athletes (CWA) and eight non habituated men (NON) volunteered to participate in a repeated measures cross-over design. The protocol was conducted in 5 °C and was 90 min of resting cold exposure, 30 min of cycle ergometry exercise (50 % VO2 peak), and 60 min of seated recovery. Core and finger skin temperature, metabolic rate, Purdue Pegboard dexterity performance, hand pain, thermal sensation, and mood were quantified. Exercise-induced finger rewarming (EIFRW) was calculated for each hand. During 90 min of resting exposure to 5 °C, the CWA had a smaller reduction in finger temperature, a lower metabolic rate, less hand pain, and less negative mood. Despite this cold habituation, dexterity performance was not different between groups. In response to cycle ergometry, EIFRW was greater in CWA (~12 versus 7 °C) and occurred at lower core temperatures (37.02 versus 37.31 °C) relative to NON but dexterity was not greater during post-exercise recovery. The current data indicate that cold habituated men (i.e., CWA) do not perform better on the Purdue Pegboard during acute cold exposure. Furthermore, despite augmented EIFRW in CWA, dexterity during post-exercise recovery was similar between groups.

    Psychostimulants have many effects on visual function, from adverse following acute and prenatal exposure to therapeutic on attention deficit. To determine the impact of prenatal and acute cocaine exposure on visual processing, we studied neuronal responses to visual stimuli in two brain regions of a transgenic larval zebrafish expressing the calcium indicator GCaMP-HS. We found that both red light (LF) and dark (DF) flashes elicited similar responses in the optic tectum neuropil (TOn), while the dorsal telencephalon (dTe) responded only to LF. Acute cocaine (0.5 μM) reduced neuronal responses to LF in both brain regions but did not affect responses to DF. Repeated stimulus presentation (RSP) led to habituation of dTe neurons to LF. Acute cocaine prevented habituation. TOn habituated to DF, but not LF, and DF habituation was not modified by cocaine. Remarkably, prenatal cocaine exposure (PCE) prevented the effects of acute cocaine on LF response amplitude and habituation later in development in both brain regions, but did not affect DF responses. We discovered that, in spite of similar neural responses to LF and DF in the TO (superior colliculus in mammals), responses to LF are more complex, involving dTe (homologous to the cerebral cortex), and are more vulnerable to cocaine. Our results demonstrate that acute cocaine exposure affects visual processing differentially by brain region, and that PCE modifies zebrafish visual processing in multiple structures in a stimulus-dependent manner. These findings are in accordance with the major role that the optic tectum and cerebral cortex play in sustaining visual attention, and support the hypothesis that modification of these areas by PCE may be responsible for visual deficits noted in humans. This model offers new methodological approaches for studying the adverse and therapeutic effects of psychostimulants on attention, and for the development of new pharmacological interventions.

    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.

  1. Abortion in Chile: the practice under a restrictive regime.

    Casas, Lidia; Vivaldi, Lieta

    2014-11-01

    This article examines, from a human rights perspective, the experience of women, and the practices of health care providers regarding abortion in Chile. Most abortions, as high as 100,000 a year, are obtained surreptitiously and clandestinely, and income and connections play a key role. The illegality of abortion correlates strongly with vulnerability, feelings of guilt and loneliness, fear of prosecution, physical and psychological harm, and social ostracism. Moreover, the absolute legal ban on abortion has a chilling effect on health care providers and endangers women's lives and health. Although misoprostol use has significantly helped to prevent greater harm and enhance women's agency, a ban on sales created a black market. Against this backdrop, feminists have taken action in aid of women. For instance, a feminist collective opened a telephone hotline, Linea Aborto Libre (Free Abortion Line), which has been crucial in informing women of the correct and safe use of misoprostol. Chile is at a crossroads. For the first time in 24 years, abortion law reform seems plausible, at least when the woman's life or health is at risk and in cases of rape and fetal anomalies incompatible with life. The political scenario is unfolding as we write. Congressional approval does not mean automatic enactment of a new law; a constitutional challenge is highly likely and will have to be overcome.

    Despite widespread awareness of and access to modern contraception, high rates of unwanted pregnancies and abortions still persist in many parts of the world, even where abortion is legally restricted. This article explores perspectives on contraception and abortion, contraceptive decision-making within relationships, and the management of unplanned pregnancies. It presents findings from an exploratory qualitative study based on 17 in-depth interviews and 6 focus group discussions conducted in 2 locations in Nigeria in 2006. The results suggest that couples do not practice contraception consistently because of perceived side effects and partner objections. Abortion is usually resorted to because pregnancy was unwanted due to incomplete educational attainment, economic hardship, immaturity, close pregnancy interval, and social stigma. Males usually have greater influence in contraceptive-decision making than females. Though induced abortion is negatively viewed in the community, it is still common, and women usually patronise quacks to obtain such services. An abortion experience can change future views and decisions towards contraception. Family planning interventions should include access to and availability of adequate family planning information. Educational campaigns should target males since they play an important role in contraceptive decision-making.

    Full Text Available In a historical cohort study we evaluated the effects of spontaneous abortion on subsequent pregnancy outcome. 1693 pregnant women were classifield in three groups: 1100: without any prior pregnancy, group 1; 550: with history of one spontaneous abortion (G2A1, group 2; 43: with two or more prior spontaneous abortions and no other prior pregnancies, group 3. We collected data through interview, patient's records and physical examination. We matched the patients according to their age subgroups, history of chronic disease, drug administration and radiation during current pregnancy and familial marriage. Then we compared adverse outcome of present pregnancy in group 1 and 2 with the women without prior pregnancy. We analysed the data with Chi-square and Fisher's exact methods. In this study we concluded that history of one spontaneous abortion had no effect on subsequent pregnancy except on prolonged ROM (P<0.000, but history of two or more abortions significantly affects occurrence of stillbirth (RR=29, P=0.003 and placenta previa (RR=8.5, P=0.03. These findings suggest that pregnant women with history of two or more spontaneous abortion need special prenatal care.

    The history of fertility regulation in Romania illustrates the complex interactions between politics, women's reproductive health and rights and access to high quality care. This paper describes the current situation of abortion and contraception in Romania, based on national statistics, recent reproductive health surveys and the findings of a strategic assessment led by the Ministry of Health in late 2001. This rapid assessment employed a participatory, qualitative methodology. Over 500 people were interviewed from 145 institutions in 25 cities, towns and villages in Romania, about the range of actions needed to prevent unwanted pregnancies, reduce abortion-related morbidity and mortality and improve the quality, accessibility and availability of abortion and contraceptive services. Although much progress has been made in contraceptive services over the past ten years, improvements in abortion care have lagged considerably The assessment played an important role in raising team members' awareness and motivation to take action. Some of the issues identified are already being addressed by the institutions that took part. National standards and guidelines for comprehensive abortion care have been developed, contraceptive services have been expanded at primary health care level, sexual and reproductive health education provided by classroom teachers has been introduced in schools, and a study to test a model of comprehensive abortion care services for Romania is planned.

    Pregnant mice, guinea pigs, rats, and rabbits responded to injections of Moraxella bovis strain EPP-63(300) with abortion, death, embryo resorption, and production of small litters. The nature of response appeared to depend primarily on the number of viable cells injected and to some extent on the species of animal and stage of pregnancy. Intraperitoneal injection of mice with 3 X 10(5) viable cells induced 100% abortion and no deaths. Embryo resorption and smaller litters were induced with injection of lower doses of M. bovis. None of the rats used in this study aborted; however, resorption rates were higher in rats than mice. Bacteria-free filtrates prepared from aqueous extracts of blood agar on which M. bovis had been grown induced abortion in mice and guinea pigs, at a rate similar to that caused by viable cells. The lyophilized filtrate could be diluted to produce 100% abortion with no death of injected mice. Abortion-inducing, nonlethal doses of M. bovis and lyophilized filtrates appeared to have no effect on nonpregnant female or male mice.

    Objective:To observe the effect of lidocaine in the application of induced abortion.Methods:A total of 120 pregnant women with 6-10 week gestational age and ASA I-II level who were volunteered to receive induced abortions from January, 2010 to January, 2013 were included in the study, among which 60 cases were given lidocaine during the operation and served as the observation group, while 60 cases were not given lidocaine during the operation and served as the control group. The heart rate, blood pressure, the change of oxygen saturation, pain, and the occurrence of abortion syndrome before and after operation between the two groups were compared.Results:The fineness rates of analgesia and anesthesia evaluation in the observation group were significantly higher than those in the control group (P0.05). The postoperative heart rate and blood pressure in the control group were significantly lower than those before operation and in the observation group with a slow recovery (P0.05). The occurrence rate of abortion syndrome in the observation group was significantly lower than that in the control group (P<0.05). Conclusions:Application of lidocaine in the induced abortion can relieve the pain and reduce the occurrence rate of abortion syndrome with a simple and safe operation; therefore, it deserves to be widely recommended.

    Conclusions: All MTP seekers should be provided information and counseling for post abortal contraceptive use and enable these women and their spouse to make an informed and voluntary choice and thus avoid the need of a repeat abortion. Contraceptive services should also include emergency contraception to prevent unwanted pregnancy due to unprotected sex. [Int J Reprod Contracept Obstet Gynecol 2016; 5(10.000: 3491-3495

  8. Towards comprehensive early abortion service delivery in high income countries: insights for improving universal access to abortion in Australia

    OpenAIRE

    2016-01-01

    Background Improving access to safe abortion is an essential strategy in the provision of universal access to reproductive health care. Australians are largely supportive of the provision of abortion and its decriminalization. However, the lack of data and the complex legal and service delivery situation impacts upon access for women seeking an early termination of pregnancy. There are no systematic reviews from a health services perspective to help direct health planners and policy makers to...

    4 maternal deaths from abortion that took place during the 6-year period from March 1968 to February 1974 in the University Hospital, Kuala Lumpur are reviewed with focus on the avoidable causes and preventive aspects. The total maternal deaths from all causes for the 1699 admission was 13. The mortality rate from abortion during this period was 0.241/1000 pregnancies. The number of abortion cases admitted into the hospital during the 6-year period increased steadily. Of the 4 abortion deaths, 3 patients admitted to attempts at inducing abortion. 1 patient denied having induced abortion, although her husband felt that it could have occurred. All 4 cases of abortion deaths occurred in patients with septic abortions and were, theoretically, avoidable deaths. It is most important to prevent sepsis in a case of abortion. Patients with endotoxic shock are often given intravenous steroids in pharmacological doses every 4-6 hours.

  10. Decriminalization of abortion in Mexico City: the effects on women's reproductive rights.

    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.

    Complications of an unsafe abortion are a major contributor to maternal deaths and morbidity in Africa. When abortions are performed in safe environments, such complications are almost all preventable. This paper reports results from a nationally representative health facility study conducted in Ethiopia in 2008. The safe abortion care (SAC) model, a monitoring approach to assess the amount, distribution, use and quality of abortion services, provided a framework. Data collection included key informant interviews with 335 health care providers, prospective data on 8911 women seeking treatment for abortion complications or induced abortion and review of facility logbooks. Although the existing hospitals perform most basic abortion care functions, the number of facilities providing basic and comprehensive abortion care for the population size fell far short of the recommended levels. Almost one-half (48%) of women treated for obstetric complications in the facilities had abortion complications. The use of appropriate abortion technologies in the first trimester and the provision of post-abortion contraception overall were reasonably strong, especially in private sector facilities. Following abortion law reform in 2005 and subsequent service expansion and improvements, Ethiopia remains committed to reducing complications from an unsafe abortion. This study provides the first national snapshot to measure changes in a dynamic abortion care environment.

    Abortion has been available legally in Moldova since 1955, and since then the abortion rate has gradually declined. The quality of abortion care remains low, however, and there is a high level of maternal mortality related to unsafe abortion. The goals of the 2005-2015 National Reproductive Health Strategy are to reduce unwanted pregnancy, reduce abortion-related morbidity and mortality, improve access to and quality of abortion care, including the methods of vacuum aspiration and medical abortion. This paper presents information on the current abortion law, policy and services in Moldova. It describes a project whose aim is to improve the quality of abortion services, including the introduction of medical abortion through training of service providers and community education. Manual vacuum aspiration has also recently been introduced. The drugs for medical abortion are officially approved, a clinical study evaluating the efficacy and acceptability of medical abortion in a low-resource setting has been completed, and training of providers has been carried out. However, institutionalisation of medical abortion faces many problems in relation to organisation of service delivery, the higher cost of medical than aspiration abortion, and doctors' reluctance to use new methods.

    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.

    A recent study in the US showed that abortion was achieved in 171/178 women aged 18 to 47 with pregnancies of 63 days or less duration through the administration of an intramuscular injection of methotrexate (a drug used to treat cancer) followed five to seven days later with a dose of misoprostol (used to treat ulcers). The report of this study prompted the founder of the anti-abortion group Operation Rescue to threaten the report's author with being "hunted down and tried for genocide" should abortion ever be made illegal. While the National Abortion Rights Action League urged that the procedure be judged on medical not political terms, a spokesperson for the National Right to Life Committee expressed concern for the reproductive and psychological health of women undergoing medical abortions. The Population Council is currently completing clinical trials of the regimen which employs RU-486 to achieve medical abortion and expects to file a new drug application with the US Food and Drug Administration (FDA) in 1996. The methotrexate/misoprostol combination would be much less expensive than RU-486 (approximately $10 compared to $250 at current prices), and a pharmaceutical company is currently attempting to raise the six million dollars necessary to fund the large-scale clinical trials which must precede FDA approval. While the availability of medical abortions would make the procedure much more accessible and private for women, proper counseling must be given to the women to avoid unwanted side effects and so that the women know what to expect.

  15. Abortion and moral development theory: listening with different ears.

    Listening to the reasons used by women to justify their action of having an abortion is a good way of determining its moral status. However, it must be remembered that the opinions one has about abortion cannot be separated from the manner in which questions are asked of these women. In fact the moral opinion of the researcher is interwoven with the methodology and questions used to interview women. This examination of the above mentioned issue takes place in the context of analyzing Carol Gilligan's book, In a Different Voice. This work will be used to illustrate how a researchers own opinions about abortion can be seen in the process of setting up a study to interview women to determine the moral value of abortion based on the moral justification of abortion seekers. There seems to be a difference of opinion about the use of the terms caring, responsible and non-violent by the women being interviewed. Gilligan states that the moral development of women occurs in 3 stages. Part of the transformation process involves women realizing the good does not necessarily involve self-sacrifice. Gilligan's treatment of the interviews is not always consistent with her own philosophical views; however, she routinely fails to ask rather obvious questions of women that may suggest that they did not reason well about their abortion decision. This ultimately is the weak link in Gilligan's analysis and theories. If you assume that women are the pivotal decision makers in determining the moral status of abortion, you must assume that they always reason correctly, which is of course not the case.

  16. Study quantifies problem of abortion in the region.

    Findings of a multicenter study that was discussed during the 1993 Health Ministers' Conference showed that about 30% of maternal deaths in east, central, and southern Africa were associated with complications of unsafe abortion. The Commonwealth Regional Health Community Secretariat in collaboration with the Support for Analysis and Research in Africa, a project funded by USAID and the Johns Hopkins Program on Training in Reproductive Health, has coordinated a study that will help guide the development of better policies on unsafe abortion. One phase involved the collection and analysis of all published and unpublished information from computer data bases dealing with the problem. The other phase involved interviews with health care workers, patients, and managers of health care facilities in Zambia, Malawi, and Uganda. In each of the 3 countries primary data was collected from a tertiary care hospital in the capital city, a provincial hospital, and 2 rural district hospitals. The results of the primary data component showed that services for the prevention of unwanted pregnancy and treatment of complications of abortion in this region are inadequate. Unsafe abortion was also a major public health problem in the region, costing national governments a lot of resources. Findings revealed that unsafe abortion is an enormous public health problem with staggering consequences for women and the health care system, which spend an inordinate amount of money, time, and other resources to treat the consequences of unsafe abortion. Complications leading to acute and chronic injuries and sometimes death, as a result of unsafe abortion, affect women at the prime of their lives. Postabortion family planning services, health care facilities, and counseling are lacking. The Recommendations and Policy Implications of the study will be discussed by the 22nd Conference of Health Ministers with a view to developing specific actions to avert the problem.

  17. A Proposed Ascent Abort Flight Test for the Max Launch Abort System

    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.

    modulation is currently inconsistent. In a double-blind placebo-controlled crossover design, 18 healthy male volunteers received either placebo or a dose of 10 mg of escitalopram (SSRI), after which they were tested in both PPI and habituation of the startle reflex paradigms. No significant differences...... between the two treatments were observed on PPI, although escitalopram was found to significantly delay habituation of the ASR. In the current study, escitalopram was found to delay habituation, but it did not affect PPI in healthy male volunteers. As escitalopram is a highly specific SSRI, the results...

    been attributed to neuronal dysexcitability. FHM and the common forms of migraine are thought to belong to a spectrum of migraine phenotypes with similar pathophysiology, and we therefore examined whether an abnormal habituation pattern would also be found in FHM patients.......Familial hemiplegic migraine (FHM) is a rare, dominantly inherited subtype of migraine with transient hemiplegia during the aura phase. Mutations in at least three different genes can produce the FHM phenotype. The mutated FHM genes code for ion transport proteins that animal and cellular studies...... have associated with disturbed ion homeostasis, altered cellular excitability, neurotransmitter release, and decreased threshold for cortical spreading depression. The common forms of migraine are characterized interictally by a habituation deficit of cortical and subcortical evoked responses that has...

  20. Habituation-based mechanism for encoding temporal information in artificial neural networks

    Stiles, Bryan W.; Ghosh, Joydeep

    1995-04-01

    A novel neural network is proposed for the dynamic classification of spatio-temporal signals. The network is designed to classify signals of different durations, taking into account correlations among different signal segments. Such a network is applicable to SONAR and speech signal classification problems, among others. Network parameters are adapted based on the biologically observed habituation mechanism. This allows the storage of contextual information, without a substantial increase in network complexity. Experiments on classification of high dimensional feature vectors obtained from Banzhaf sonograms, demonstrate that the proposed network performs better than time delay neural networks while using a less complex structure. A mathematical justification of the capabilities of the habituation based mechanism is also provided.
